TBC Macros and Extensions

Hi guys,

does any of you have experience with supporting proxy server settings in your TBC macros?

I´ve used several TML built-in functions in some of my macros to check internet connection and get the current datum from the internet (instead of from the local system) such us:

public static System.Threading.Tasks.Task<bool> IsInternetConnectionAvailableAsync()
    Member von Trimble.Vce.TbcLicense.HardenedManager

public static System.DateTime GetCurrentDate()
    Member von Trimble.Vce.TbcLicense.HardenedManager

However from TBC version to version, these was moved to other places etc, and even there were other functions such us IsInternetConnectionAvailable() that no longer exist, but the new one does not work and gives back always True although there is no internet connection or there is but due to the proxy settings, no real "connection" to the "ouside world" is possible. As this built-in function finish to work properly a couple of TBC versions ago, I changed the internet connection check by using sockets.

Furthermore since 2023.10 some customers who have been using proxy server settings and my macros worked with the own internet connection check via sockets i.e., it does not work any more:

## see if we can resolve the host name -- tells us if there is
## a DNS listening
host = socket.gethostbyname("http://google.com")
## connect to the host -- tells us if the host is actually reachable

s = socket.create_connection((host, 80), 2)
s.close()

So basically, there are a lot of Python functions to check the internet connection or read the current date from the internet, however not working for IronPython, so my question would be if some of you knows how to check the internet connection and current date from the internet (obviously if there is an internet connection) from IronPython or if there is any other (working ;-) ) TML built-in function for that. The GetCurrentDate() one works indeed, however not the other one for the internet connection.

For example, I would like to use the urllib module, however it does not work from the Macro itself although the module and its function is recognized in the code:

, but giving "ImportError: No module named 'urllib'" error when launching the macro inside TBC.

Any help or recommendation would be highly appreciated.

Thanks.

Regards,

Fernando

Hi again,

26 days waiting (as usual as with many other threads and direct questions ) for an answer by the TBC development team, at least to say that it is not possible or whatever, but nothing happens.

Is it really the goal of this forum to create it and leave the developers alone and if no answer from other TML developer (unfortunately max. 5-10 worldwide), then you can be waiting for years for an answer?

Is it so difficult to invest 30 Minutes of your time (TBC team) per week or month to check the questions and issue in this forum? There are just 3-5 threads per month, so it´s not a major time investment from your side.

Thanks.

Regards,

Fernando

Hello Fernando,

Sorry for the delay in our response to your question. Gary Lantaff is no longer with Trimble so the monitoring of this community wasn't a high priority. We have put a plan in place to actively monitor and reply to questions in a more timely manor. Your question is currently being researched. We hope to have an answer soon.

Hi Fernando,

Sorry for the late reply - I meant to reply to your post a couple weeks ago...

Since the public TBC command extension mechanism uses IronPython, you have 3 different sources for coding solutions:
1) Python (like you are trying above)
2) .NET Framework 4.8 (this is the .NET version that TBC v5.50+ uses)
3) TBC API libraries (like the HardenedManager you mentioned above)

So if you're having trouble with 1) or 3), you can always Google for answers from .NET Framework 4.8 - there should be a large pool of posts (or debates!) since that is a longstanding platform.

I did a 10-minute browse and found numerous answers - several examples were "pinging" something well-known like Google.com.  Like many code searches, it seemed there was not a quick answer.  It seemed like most people were asking this question (how to check for an internet connection) because they wanted to avoid making a web call and waiting for a timeout.

In my case, I am starting out with using HttpClient (from System.Net.Http) and using the PostAsync() and GetAsync() methods, and using Task.Wait(5000) for a 5-second timeout.  I appreciate that I'll need fancier code to display a cancelable progress bar in the UI, etc., but this is OK just to get things working (for now).  Your web code may be well beyond this basic usage...

Also, sort of a side comment, but thanks for sharing (over the years) some of your exploration into using the HardenedManager!

I had a customer request to be able to associate command license checks with the hardware and software key IDs used by TBC and was able to use it successfully.  I also updated my code to use HardenedManager.GetCurrentDate(), so my license check uses the same date that TBC uses (whatever strategy it uses to determine the date).

Hope some of that helps,

Hi Quan,

thanks so much for your answer and whole recommendations, and please, you don´t need to apologize, it´s not your job as you are like myself a 3rd party developer, so special thanks for dedicating time to help me.

I tried indeed dozens of ways that I found on the internet but I didn´t find a way to get it working, especially when working with proxies, although I guess TBC should also support proxies in any way as hundreds or thousands of customers, especially public administration, only work via VPN and/or proxy, however I don´t see any setting inside TBC to set the IP and port as I see in other software packages. Some other solutions ask if they should use the already available proxy settings from Windows.

As Paul Garno also replied and they are researching it, let´s wait what they say and hopefully there is any function from the sdk that we can easily use similar to the GetCurrentDate but also supporting proxies etc.

Thanks.

Regards,

Fernando

Hi Fernando,

It's tricky being an extension developer - you have to figure out whether the issue you're wrestling with is a Python issue, a .NET issue, or a TBC API issue.

Issues with the TBC API (like "HardenedManager.IsInternetConnectionAvailableAsync() doesn't work with proxies") are clearly TBC dev team issues.

However, "how do I make Python web calls work with proxies" sure sounds like a Python education issue.

But... as we see from Virginia's response, it looks like TBC has a Python installation error... hopefully they can get that resolved for 2024.00 - and you can get your code working again.

Hi Fernando,

To address the urllib import error that you are seeing, please navigate to the library of IronPython files included in your TBC installation (this should be something like C:\Program Files\Trimble\Trimble Business Center\IronPython 3.4\Lib), and rename the urlib folder to urllib.

This issue should be resolved for future releases.

Thank you for your patience!

Hi Virgina,

thanks so much for your reply and information ! Really appreciate it !

It´s working now after changing the folder name. I think I found something similar during my dozens of tests of different workarounds or ways but I think it was not the folder but the name itself as in former python versions it was called urlib and in newers urllib and also some references to urllib2 vs urllib3 or similar.

I´ll try much deeper but at the first sight, I have now access to the urllib.requests and can even read the proxy settings etc, so trying to make my internet checks bypassing the proxies, etc. BTW is TBC simply checking the current Windows proxy settings and using them to make the internet license checks etc? or is there any other function inside the SDK to ge an easier access to it such us GetCurrentDate ? However GetCurrentDate needs a "proper" internet connection without checking anything, so if no "real" internet connection, then you get a date of 1999 or so and the builg-in "IsInternetConnection...." does not work as it always gives back True although no internet available.

Thanks again for your valuable support !

Regards,

Fernando

To address the urllib import error that you are seeing, please navigate to the library of IronPython files included in your TBC installation (this should be something like C:\Program Files\Trimble\Trimble Business Center\IronPython 3.4\Lib), and rename the urlib folder to urllib.

This issue should be resolved for future releases.

Thank you for your patience!

Subject: Supporting proxy settings and checking date from the internet

Hi guys,

does any of you have experience with supporting proxy server settings in your TBC macros?

I´ve used several TML built-in functions in some of my macros to check internet connection and get the current datum from the internet (instead of from the local system) such us:

public static System.Threading.Tasks.Task<bool> IsInternetConnectionAvailableAsync()
    Member von Trimble.Vce.TbcLicense.HardenedManager

public static System.DateTime GetCurrentDate()
    Member von Trimble.Vce.TbcLicense.HardenedManager

However from TBC version to version, these was moved to other places etc, and even there were other functions such us IsInternetConnectionAvailable() that no longer exist, but the new one does not work and gives back always True although there is no internet connection or there is but due to the proxy settings, no real "connection" to the "ouside world" is possible. As this built-in function finish to work properly a couple of TBC versions ago, I changed the internet connection check by using sockets.

Furthermore since 2023.10 some customers who have been using proxy server settings and my macros worked with the own internet connection check via sockets i.e., it does not work any more:

## see if we can resolve the host name -- tells us if there is
## a DNS listening
host = socket.gethostbyname("http://google.com")
## connect to the host -- tells us if the host is actually reachable

s = socket.create_connection((host, 80), 2)
s.close()

So basically, there are a lot of Python functions to check the internet connection or read the current date from the internet, however not working for IronPython, so my question would be if some of you knows how to check the internet connection and current date from the internet (obviously if there is an internet connection) from IronPython or if there is any other (working ;-) ) TML built-in function for that. The GetCurrentDate() one works indeed, however not the other one for the internet connection.

For example, I would like to use the urllib module, however it does not work from the Macro itself although the module and its function is recognized in the code:

, but giving "ImportError: No module named 'urllib'" error when launching the macro inside TBC.

Any help or recommendation would be highly appreciated.

Thanks.

Regards,

Fernando

Hi again, 

just a quick correction when using GetCurrentDate, so if no internet connection or not able to go through the proxies, we get back 31.12.9999 as you can see in the following screenshot and the first row showing the date via urllib:

Thanks.

Hi Virgina,

thanks so much for your reply and information ! Really appreciate it !

It´s working now after changing the folder name. I think I found something similar during my dozens of tests of different workarounds or ways but I think it was not the folder but the name itself as in former python versions it was called urlib and in newers urllib and also some references to urllib2 vs urllib3 or similar.

I´ll try much deeper but at the first sight, I have now access to the urllib.requests and can even read the proxy settings etc, so trying to make my internet checks bypassing the proxies, etc. BTW is TBC simply checking the current Windows proxy settings and using them to make the internet license checks etc? or is there any other function inside the SDK to ge an easier access to it such us GetCurrentDate ? However GetCurrentDate needs a "proper" internet connection without checking anything, so if no "real" internet connection, then you get a date of 1999 or so and the builg-in "IsInternetConnection...." does not work as it always gives back True although no internet available.

Thanks again for your valuable support !

Regards,

Fernando

Hi Fernando, 

Sorry for all your troubles.

For the HardenedManager, I am confused why you believe that IsInternetConnectAvailableAsync always returns true. I can confirm we ping multiple locations to determine if we have a connection. If any succeed, we return true, otherwise false. If you are offline, those calls will fail and return false. 

I have taken a screenshot below demonstrating IsInternetConnectionAvailableAsync (see wifi connection in toolbar to confirm offline) and see the call working as expected. 

GetCurrentDate is similar in we ping multiple servers to get the correct location. If this fails (ie offline), we return the DateTime.MaxValue (12/31/9999) as you have demonstrated in your screenshot above. I believe you misread the year value as 1999, not 9999. 

I hope this helps in understanding what is happening in these calls. You are more than welcome to try to use the HardenedManager or roll your own solution with the python libraries. I do not see any glaring issues at this time with the HardenedManager and its responses. 

Good Luck!

Hi Bryce,

thanks a lot for your reply and infos !

Regarding IsInternetConnectionAvailableAsync(), I have tried now even some "stupid" code (especially the else as it makes no sense but just to see what comes as I got False although I had now an internet connection), that I would never use, but just to see what happens:

And without a current internet connection:

So as my original code was assuming I´m getting back either True or False, my else was for getting False and therefore getting always False, however we are getting neither True nor False...Sorry if I´m missing or overseeing anything but  I don´t understand it.

Furthermore, in my own case without proxies, if I use the GetCurrentDate(), I automatically get within 1 second the maximum date with year=9999 which is fine, however when using Proxies, it takes around 2 minutes while I can´t do anything inside TBC and apparently no timeout or too long set, and after that, I get the corresponding message.

I´m now supporting proxies by setting IP and Port, and additionally User and Password if also needed, and it works fine using the urllib, so I´ll continue from now using my own code, however it would be highly appreciated if you can check the IsInternetAvailable.. and GetCurrentDate as mentioned above.

Thanks again for your support.

IsInternetConnectionAvailableAsync is a Task<bool>, not a boolean. You need to await the task for the response. The response of "nothing" makes sense because it is neither true or false, it is a Task<bool>. 

GetCurrentDate is a synchronous call (not a Task), so it will block the calling thread in this case until it completes. The default timeout for this request is 100 seconds, which makes sense why it returns ~2 minutes later. The call tries for that time period and eventually gives up and returns the DateTime.MaxValue. 

I would recommend that whatever solution you come up with, you make the HTTP request calls on a background thread and do not block the UI for a better user experience. 

Hope this helps!

Hi Bryce,

thanks again for your response, especially because I´m not used to get any response at all, so I highly appreciate it ! ;-)

I´m pretty sure I used the function in the past in former TBC versions and I got a boolean back and probably this is the reason why it didn´t work in my macros any longer from a special TBC version, or I used another IsInternetConnection...without asynchronus in the past or similar, not sure, now, but anyway now I know that it´s a task and I can check it properly (for sure it can be checked in the object catalogue, however as I say, I´m pretty sure it was a boolean in the past, but through my thousands of tests and changes to get my macros working from version to version due to the changes, I cannot guarantee now without checking all code and all macros skd´s, if it was a boolean or not).

As I now have access to urllib, I´ll do my internet connection and date checks using it, but thanks for your recommendation for using a background thread, I´ll try it ;-)

So thanks again for your fantastic support !

Regards,

Fernando

I think I found something similar during my dozens of tests of different workarounds or ways but I think it was not the folder but the name itself as in former python versions it was called urlib and in newers urllib and also some references to urllib2 vs urllib3 or similar.

I´ll try much deeper but at the first sight, I have now access to the urllib.requests and can even read the proxy settings etc, so trying to make my internet checks bypassing the proxies, etc. BTW is TBC simply checking the current Windows proxy settings and using them to make the internet license checks etc? or is there any other function inside the SDK to ge an easier access to it such us GetCurrentDate ? However GetCurrentDate needs a "proper" internet connection without checking anything, so if no "real" internet connection, then you get a date of 1999 or so and the builg-in "IsInternetConnection...." does not work as it always gives back True although no internet available.

Thanks again for your valuable support !

Hi Fernando,

To address the urllib import error that you are seeing, please navigate to the library of IronPython files included in your TBC installation (this should be something like C:\Program Files\Trimble\Trimble Business Center\IronPython 3.4\Lib), and rename the urlib folder to urllib.

This issue should be resolved for future releases.

Thank you for your patience!

Subject: Supporting proxy settings and checking date from the internet

Hi guys,

does any of you have experience with supporting proxy server settings in your TBC macros?

I´ve used several TML built-in functions in some of my macros to check internet connection and get the current datum from the internet (instead of from the local system) such us:

public static System.Threading.Tasks.Task<bool> IsInternetConnectionAvailableAsync()
    Member von Trimble.Vce.TbcLicense.HardenedManager

public static System.DateTime GetCurrentDate()
    Member von Trimble.Vce.TbcLicense.HardenedManager

However from TBC version to version, these was moved to other places etc, and even there were other functions such us IsInternetConnectionAvailable() that no longer exist, but the new one does not work and gives back always True although there is no internet connection or there is but due to the proxy settings, no real "connection" to the "ouside world" is possible. As this built-in function finish to work properly a couple of TBC versions ago, I changed the internet connection check by using sockets.

Furthermore since 2023.10 some customers who have been using proxy server settings and my macros worked with the own internet connection check via sockets i.e., it does not work any more:

## see if we can resolve the host name -- tells us if there is
## a DNS listening
host = socket.gethostbyname("http://google.com")
## connect to the host -- tells us if the host is actually reachable

s = socket.create_connection((host, 80), 2)
s.close()

So basically, there are a lot of Python functions to check the internet connection or read the current date from the internet, however not working for IronPython, so my question would be if some of you knows how to check the internet connection and current date from the internet (obviously if there is an internet connection) from IronPython or if there is any other (working ;-) ) TML built-in function for that. The GetCurrentDate() one works indeed, however not the other one for the internet connection.

For example, I would like to use the urllib module, however it does not work from the Macro itself although the module and its function is recognized in the code:

, but giving "ImportError: No module named 'urllib'" error when launching the macro inside TBC.

Any help or recommendation would be highly appreciated.

Thanks.

Regards,

Fernando

Hi @Virginia Hutchinson and @Bryce Haire,

so far it´s working fine all that I did with urllib, however struggling for older versions such us TBC v5.81 and older.

As you mentioned, for v5.90 or 2023, the urllib is placed on:

C:\Program Files\Trimble\TBC v2023.10\IronPython 3.4\Lib\urllib

and the correction of the folder name was done for TBC v2024, which is fine, thanks for that ;-)

For TBC v5.80 the corresponding folder is:

C:\Program Files\Trimble\TBC v5.81\IronPython2.7\Lib

so I see on that folder urllib.py and urllib2.py but the macro fails when trying to load them. Is there anything we need to change to get them loaded on launch?

At least backwards up to v5.41 I can see that folder and both urllib´s .py

Thanks.

Regards,

Fernando

Hi Bryce,

thanks again for your response, especially because I´m not used to get any response at all, so I highly appreciate it ! ;-)

I´m pretty sure I used the function in the past in former TBC versions and I got a boolean back and probably this is the reason why it didn´t work in my macros any longer from a special TBC version, or I used another IsInternetConnection...without asynchronus in the past or similar, not sure, now, but anyway now I know that it´s a task and I can check it properly (for sure it can be checked in the object catalogue, however as I say, I´m pretty sure it was a boolean in the past, but through my thousands of tests and changes to get my macros working from version to version due to the changes, I cannot guarantee now without checking all code and all macros skd´s, if it was a boolean or not).

As I now have access to urllib, I´ll do my internet connection and date checks using it, but thanks for your recommendation for using a background thread, I´ll try it ;-)

So thanks again for your fantastic support !

Regards,

Fernando

IsInternetConnectionAvailableAsync is a Task<bool>, not a boolean. You need to await the task for the response. The response of "nothing" makes sense because it is neither true or false, it is a Task<bool>. 

GetCurrentDate is a synchronous call (not a Task), so it will block the calling thread in this case until it completes. The default timeout for this request is 100 seconds, which makes sense why it returns ~2 minutes later. The call tries for that time period and eventually gives up and returns the DateTime.MaxValue. 

I would recommend that whatever solution you come up with, you make the HTTP request calls on a background thread and do not block the UI for a better user experience. 

Hope this helps!

Hi Bryce,

thanks a lot for your reply and infos !

Regarding IsInternetConnectionAvailableAsync(), I have tried now even some "stupid" code (especially the else as it makes no sense but just to see what comes as I got False although I had now an internet connection), that I would never use, but just to see what happens:

And without a current internet connection:

So as my original code was assuming I´m getting back either True or False, my else was for getting False and therefore getting always False, however we are getting neither True nor False...Sorry if I´m missing or overseeing anything but  I don´t understand it.

Furthermore, in my own case without proxies, if I use the GetCurrentDate(), I automatically get within 1 second the maximum date with year=9999 which is fine, however when using Proxies, it takes around 2 minutes while I can´t do anything inside TBC and apparently no timeout or too long set, and after that, I get the corresponding message.

I´m now supporting proxies by setting IP and Port, and additionally User and Password if also needed, and it works fine using the urllib, so I´ll continue from now using my own code, however it would be highly appreciated if you can check the IsInternetAvailable.. and GetCurrentDate as mentioned above.

Thanks again for your support.

Regards,

Fernando

Hi Fernando, 

Sorry for all your troubles.

For the HardenedManager, I am confused why you believe that IsInternetConnectAvailableAsync always returns true. I can confirm we ping multiple locations to determine if we have a connection. If any succeed, we return true, otherwise false. If you are offline, those calls will fail and return false. 

I have taken a screenshot below demonstrating IsInternetConnectionAvailableAsync (see wifi connection in toolbar to confirm offline) and see the call working as expected. 

GetCurrentDate is similar in we ping multiple servers to get the correct location. If this fails (ie offline), we return the DateTime.MaxValue (12/31/9999) as you have demonstrated in your screenshot above. I believe you misread the year value as 1999, not 9999. 

I hope this helps in understanding what is happening in these calls. You are more than welcome to try to use the HardenedManager or roll your own solution with the python libraries. I do not see any glaring issues at this time with the HardenedManager and its responses. 

Good Luck!

Hi again, 

just a quick correction when using GetCurrentDate, so if no internet connection or not able to go through the proxies, we get back 31.12.9999 as you can see in the following screenshot and the first row showing the date via urllib:

Thanks.

Fernando

s.close()

So basically, there are a lot of Python functions to check the internet connection or read the current date from the internet, however not working for IronPython, so my question would be if some of you knows how to check the internet connection and current date from the internet (obviously if there is an internet connection) from IronPython or if there is any other (working ;-) ) TML built-in function for that. The GetCurrentDate() one works indeed, however not the other one for the internet connection.

For example, I would like to use the urllib module, however it does not work from the Macro itself although the module and its function is recognized in the code:

, but giving "ImportError: No module named 'urllib'" error when launching the macro inside TBC.

Any help or recommendation would be highly appreciated.

Thanks.

Fernando

Hi Fernando,
I found a couple StackOverflow posts on having a Python 2 and Python 3 compatible version of urllib/urllib2. 

https://stackoverflow.com/a/60121758

https://stackoverflow.com/a/17510727

Unfortunately, urllib appears to be a package that had some changes between the Python versions that you need to account for. 

Hi Bryce,

thanks so much for your quick response and infos!

I used so far urllib for my macros and not urllib2, but I´ll have a look at it in case urllib cannot be used for TBC v5.81 or older. Can you confirm that it wouldn´t work with urllib? or if there is any other way to work with urllib instead of urllib2 in order to avoid changing the code again and checking if urllib2 also works on 5.90 and 2023?

Regards,

Fernando

Hi Fernando,

This seems to work for v5.81.

....

Hi @Virginia Hutchinson and @Bryce Haire,

so far it´s working fine all that I did with urllib, however struggling for older versions such us TBC v5.81 and older.

As you mentioned, for v5.90 or 2023, the urllib is placed on:

C:\Program Files\Trimble\TBC v2023.10\IronPython 3.4\Lib\urllib

and the correction of the folder name was done for TBC v2024, which is fine, thanks for that ;-)

For TBC v5.80 the corresponding folder is:

C:\Program Files\Trimble\TBC v5.81\IronPython2.7\Lib

so I see on that folder urllib.py and urllib2.py but the macro fails when trying to load them. Is there anything we need to change to get them loaded on launch?

At least backwards up to v5.41 I can see that folder and both urllib´s .py

Thanks.

Regards,

Fernando

Hi Bryce,

thanks again for your response, especially because I´m not used to get any response at all, so I highly appreciate it ! ;-)

I´m pretty sure I used the function in the past in former TBC versions and I got a boolean back and probably this is the reason why it didn´t work in my macros any longer from a special TBC version, or I used another IsInternetConnection...without asynchronus in the past or similar, not sure, now, but anyway now I know that it´s a task and I can check it properly (for sure it can be checked in the object catalogue, however as I say, I´m pretty sure it was a boolean in the past, but through my thousands of tests and changes to get my macros working from version to version due to the changes, I cannot guarantee now without checking all code and all macros skd´s, if it was a boolean or not).

As I now have access to urllib, I´ll do my internet connection and date checks using it, but thanks for your recommendation for using a background thread, I´ll try it ;-)

So thanks again for your fantastic support !

Regards,

Fernando

IsInternetConnectionAvailableAsync is a Task<bool>, not a boolean. You need to await the task for the response. The response of "nothing" makes sense because it is neither true or false, it is a Task<bool>. 

GetCurrentDate is a synchronous call (not a Task), so it will block the calling thread in this case until it completes. The default timeout for this request is 100 seconds, which makes sense why it returns ~2 minutes later. The call tries for that time period and eventually gives up and returns the DateTime.MaxValue. 

I would recommend that whatever solution you come up with, you make the HTTP request calls on a background thread and do not block the UI for a better user experience. 

Hope this helps!

Hi Bryce,

thanks a lot for your reply and infos !

Regarding IsInternetConnectionAvailableAsync(), I have tried now even some "stupid" code (especially the else as it makes no sense but just to see what comes as I got False although I had now an internet connection), that I would never use, but just to see what happens:

And without a current internet connection:

So as my original code was assuming I´m getting back either True or False, my else was for getting False and therefore getting always False, however we are getting neither True nor False...Sorry if I´m missing or overseeing anything but  I don´t understand it.

Furthermore, in my own case without proxies, if I use the GetCurrentDate(), I automatically get within 1 second the maximum date with year=9999 which is fine, however when using Proxies, it takes around 2 minutes while I can´t do anything inside TBC and apparently no timeout or too long set, and after that, I get the corresponding message.

I´m now supporting proxies by setting IP and Port, and additionally User and Password if also needed, and it works fine using the urllib, so I´ll continue from now using my own code, however it would be highly appreciated if you can check the IsInternetAvailable.. and GetCurrentDate as mentioned above.

Thanks again for your support.

Regards,

Fernando

Hi Fernando, 

Sorry for all your troubles.

For the HardenedManager, I am confused why you believe that IsInternetConnectAvailableAsync always returns true. I can confirm we ping multiple locations to determine if we have a connection. If any succeed, we return true, otherwise false. If you are offline, those calls will fail and return false. 

I have taken a screenshot below demonstrating IsInternetConnectionAvailableAsync (see wifi connection in toolbar to confirm offline) and see the call working as expected. 

GetCurrentDate is similar in we ping multiple servers to get the correct location. If this fails (ie offline), we return the DateTime.MaxValue (12/31/9999) as you have demonstrated in your screenshot above. I believe you misread the year value as 1999, not 9999. 

I hope this helps in understanding what is happening in these calls. You are more than welcome to try to use the HardenedManager or roll your own solution with the python libraries. I do not see any glaring issues at this time with the HardenedManager and its responses. 

Good Luck!

Hi again, 

just a quick correction when using GetCurrentDate, so if no internet connection or not able to go through the proxies, we get back 31.12.9999 as you can see in the following screenshot and the first row showing the date via urllib:

Thanks.

Hi Virgina,

thanks so much for your reply and information ! Really appreciate it !

It´s working now after changing the folder name. I think I found something similar during my dozens of tests of different workarounds or ways but I think it was not the folder but the name itself as in former python versions it was called urlib and in newers urllib and also some references to urllib2 vs urllib3 or similar.

I´ll try much deeper but at the first sight, I have now access to the urllib.requests and can even read the proxy settings etc, so trying to make my internet checks bypassing the proxies, etc. BTW is TBC simply checking the current Windows proxy settings and using them to make the internet license checks etc? or is there any other function inside the SDK to ge an easier access to it such us GetCurrentDate ? However GetCurrentDate needs a "proper" internet connection without checking anything, so if no "real" internet connection, then you get a date of 1999 or so and the builg-in "IsInternetConnection...." does not work as it always gives back True although no internet available.

Thanks again for your valuable support !

Hi Fernando,

To address the urllib import error that you are seeing, please navigate to the library of IronPython files included in your TBC installation (this should be something like C:\Program Files\Trimble\Trimble Business Center\IronPython 3.4\Lib), and rename the urlib folder to urllib.

This issue should be resolved for future releases.

Thank you for your patience!

Hi guys,

does any of you have experience with supporting proxy server settings in your TBC macros?

I´ve used several TML built-in functions in some of my macros to check internet connection and get the current datum from the internet (instead of from the local system) such us:

public static System.Threading.Tasks.Task<bool> IsInternetConnectionAvailableAsync()
    Member von Trimble.Vce.TbcLicense.HardenedManager

public static System.DateTime GetCurrentDate()
    Member von Trimble.Vce.TbcLicense.HardenedManager

However from TBC version to version, these was moved to other places etc, and even there were other functions such us IsInternetConnectionAvailable() that no longer exist, but the new one does not work and gives back always True although there is no internet connection or there is but due to the proxy settings, no real "connection" to the "ouside world" is possible. As this built-in function finish to work properly a couple of TBC versions ago, I changed the internet connection check by using sockets.

Furthermore since 2023.10 some customers who have been using proxy server settings and my macros worked with the own internet connection check via sockets i.e., it does not work any more:

## see if we can resolve the host name -- tells us if there is
## a DNS listening
host = socket.gethostbyname("http://google.com")
## connect to the host -- tells us if the host is actually reachable

s = socket.create_connection((host, 80), 2)
s.close()

So basically, there are a lot of Python functions to check the internet connection or read the current date from the internet, however not working for IronPython, so my question would be if some of you knows how to check the internet connection and current date from the internet (obviously if there is an internet connection) from IronPython or if there is any other (working ;-) ) TML built-in function for that.

Hi Bryce,

thanks for your reply. I knew a bit about the differences indeed, but my question was more if there is also any known issue with false naming (such us urlib instead of urllib, or false folder or the need to create a subfolder named "urllib" or similar), as my main issue is that TBC cannot load the "urllib" module, so similar to the issue that I had with v5.90 or higher due to the incorrect naming of the urllib folder during TBC´s installation.

thanks.

Hey Fernando,

Upcoming TBC 2024.00 has addressed the naming of the folder to the correct naming (urllib). There should be no need to either rename a folder or use the incorrect module name (urlib).

host = socket.gethostbyname("http://google.com")
## connect to the host -- tells us if the host is actually reachable

s = socket.create_connection((host, 80), 2)
s.close()

So basically, there are a lot of Python functions to check the internet connection or read the current date from the internet, however not working for IronPython, so my question would be if some of you knows how to check the internet connection and current date from the internet (obviously if there is an internet connection) from IronPython or if there is any other (working ;-) ) TML built-in function for that. The GetCurrentDate() one works indeed, however not the other one for the internet connection.

For example, I would like to use the urllib module, however it does not work from the Macro itself although the module and its function is recognized in the code:

, but giving "ImportError: No module named 'urllib'" error when launching the macro inside TBC.

Any help or recommendation would be highly appreciated.

Thanks.

Fernando

Hi Bryce,

thanks, I noticed it already while testing the Beta version, which is great, thanks for fixing it.

The question is if there is anything similar for 5.81 and older as TBC cannot import urllib although the urllib.py exists on the corresponding folder.

Thanks.

Fernando

Hey Fernando,

Upcoming TBC 2024.00 has addressed the naming of the folder to the correct naming (urllib). There should be no need to either rename a folder or use the incorrect module name (urlib). 

Hi Bryce,

thanks for your reply. I knew a bit about the differences indeed, but my question was more if there is also any known issue with false naming (such us urlib instead of urllib, or false folder or the need to create a subfolder named "urllib" or similar), as my main issue is that TBC cannot load the "urllib" module, so similar to the issue that I had with v5.90 or higher due to the incorrect naming of the urllib folder during TBC´s installation.

thanks.

Regards,

Fernando

Hi Fernando,
I found a couple StackOverflow posts on having a Python 2 and Python 3 compatible version of urllib/urllib2. 

https://stackoverflow.com/a/60121758

https://stackoverflow.com/a/17510727

Unfortunately, urllib appears to be a package that had some changes between the Python versions that you need to account for. 

Hi Bryce,

thanks so much for your quick response and infos!

I used so far urllib for my macros and not urllib2, but I´ll have a look at it in case urllib cannot be used for TBC v5.81 or older. Can you confirm that it wouldn´t work with urllib? or if there is any other way to work with urllib instead of urllib2 in order to avoid changing the code again and checking if urllib2 also works on 5.90 and 2023?

Regards,

Fernando

Hi Fernando,

This seems to work for v5.81.

....

Hi @Virginia Hutchinson and @Bryce Haire,

so far it´s working fine all that I did with urllib, however struggling for older versions such us TBC v5.81 and older.

As you mentioned, for v5.90 or 2023, the urllib is placed on:

C:\Program Files\Trimble\TBC v2023.10\IronPython 3.4\Lib\urllib

and the correction of the folder name was done for TBC v2024, which is fine, thanks for that ;-)

For TBC v5.80 the corresponding folder is:

C:\Program Files\Trimble\TBC v5.81\IronPython2.7\Lib

so I see on that folder urllib.py and urllib2.py but the macro fails when trying to load them. Is there anything we need to change to get them loaded on launch?

At least backwards up to v5.41 I can see that folder and both urllib´s .py

Thanks.

Regards,

Fernando

Hi Bryce,

thanks again for your response, especially because I´m not used to get any response at all, so I highly appreciate it ! ;-)

I´m pretty sure I used the function in the past in former TBC versions and I got a boolean back and probably this is the reason why it didn´t work in my macros any longer from a special TBC version, or I used another IsInternetConnection...without asynchronus in the past or similar, not sure, now, but anyway now I know that it´s a task and I can check it properly (for sure it can be checked in the object catalogue, however as I say, I´m pretty sure it was a boolean in the past, but through my thousands of tests and changes to get my macros working from version to version due to the changes, I cannot guarantee now without checking all code and all macros skd´s, if it was a boolean or not).

As I now have access to urllib, I´ll do my internet connection and date checks using it, but thanks for your recommendation for using a background thread, I´ll try it ;-)

So thanks again for your fantastic support !

Regards,

Fernando

IsInternetConnectionAvailableAsync is a Task<bool>, not a boolean. You need to await the task for the response. The response of "nothing" makes sense because it is neither true or false, it is a Task<bool>. 

GetCurrentDate is a synchronous call (not a Task), so it will block the calling thread in this case until it completes. The default timeout for this request is 100 seconds, which makes sense why it returns ~2 minutes later. The call tries for that time period and eventually gives up and returns the DateTime.MaxValue. 

I would recommend that whatever solution you come up with, you make the HTTP request calls on a background thread and do not block the UI for a better user experience. 

Hope this helps!

Hi Bryce,

thanks a lot for your reply and infos !

Regarding IsInternetConnectionAvailableAsync(), I have tried now even some "stupid" code (especially the else as it makes no sense but just to see what comes as I got False although I had now an internet connection), that I would never use, but just to see what happens:

And without a current internet connection:

So as my original code was assuming I´m getting back either True or False, my else was for getting False and therefore getting always False, however we are getting neither True nor False...Sorry if I´m missing or overseeing anything but  I don´t understand it.

Furthermore, in my own case without proxies, if I use the GetCurrentDate(), I automatically get within 1 second the maximum date with year=9999 which is fine, however when using Proxies, it takes around 2 minutes while I can´t do anything inside TBC and apparently no timeout or too long set, and after that, I get the corresponding message.

I´m now supporting proxies by setting IP and Port, and additionally User and Password if also needed, and it works fine using the urllib, so I´ll continue from now using my own code, however it would be highly appreciated if you can check the IsInternetAvailable.. and GetCurrentDate as mentioned above.

Thanks again for your support.

Regards,

Fernando

Hi Fernando, 

Sorry for all your troubles.

For the HardenedManager, I am confused why you believe that IsInternetConnectAvailableAsync always returns true. I can confirm we ping multiple locations to determine if we have a connection. If any succeed, we return true, otherwise false. If you are offline, those calls will fail and return false. 

I have taken a screenshot below demonstrating IsInternetConnectionAvailableAsync (see wifi connection in toolbar to confirm offline) and see the call working as expected. 

GetCurrentDate is similar in we ping multiple servers to get the correct location. If this fails (ie offline), we return the DateTime.MaxValue (12/31/9999) as you have demonstrated in your screenshot above. I believe you misread the year value as 1999, not 9999. 

I hope this helps in understanding what is happening in these calls. You are more than welcome to try to use the HardenedManager or roll your own solution with the python libraries. I do not see any glaring issues at this time with the HardenedManager and its responses. 

Good Luck!

Hi again, 

just a quick correction when using GetCurrentDate, so if no internet connection or not able to go through the proxies, we get back 31.12.9999 as you can see in the following screenshot and the first row showing the date via urllib:

Thanks.

Fernando

Hi Virgina,

thanks so much for your reply and information ! Really appreciate it !

It´s working now after changing the folder name. I think I found something similar during my dozens of tests of different workarounds or ways but I think it was not the folder but the name itself as in former python versions it was called urlib and in newers urllib and also some references to urllib2 vs urllib3 or similar.

I´ll try much deeper but at the first sight, I have now access to the urllib.requests and can even read the proxy settings etc, so trying to make my internet checks bypassing the proxies, etc. BTW is TBC simply checking the current Windows proxy settings and using them to make the internet license checks etc? or is there any other function inside the SDK to ge an easier access to it such us GetCurrentDate ? However GetCurrentDate needs a "proper" internet connection without checking anything, so if no "real" internet connection, then you get a date of 1999 or so and the builg-in "IsInternetConnection...." does not work as it always gives back True although no internet available.

Thanks again for your valuable support !

Hi Fernando,

To address the urllib import error that you are seeing, please navigate to the library of IronPython files included in your TBC installation (this should be something like C:\Program Files\Trimble\Trimble Business Center\IronPython 3.4\Lib), and rename the urlib folder to urllib.

This issue should be resolved for future releases.

Hi guys,

does any of you have experience with supporting proxy server settings in your TBC macros?

I´ve used several TML built-in functions in some of my macros to check internet connection and get the current datum from the internet (instead of from the local system) such us:

public static System.Threading.Tasks.Task<bool> IsInternetConnectionAvailableAsync()
    Member von Trimble.Vce.TbcLicense.HardenedManager

public static System.DateTime GetCurrentDate()
    Member von Trimble.Vce.TbcLicense.HardenedManager

However from TBC version to version, these was moved to other places etc, and even there were other functions such us IsInternetConnectionAvailable() that no longer exist, but the new one does not work and gives back always True although there is no internet connection or there is but due to the proxy settings, no real "connection" to the "ouside world" is possible. As this built-in function finish to work properly a couple of TBC versions ago, I changed the internet connection check by using sockets.

Furthermore since 2023.10 some customers who have been using proxy server settings and my macros worked with the own internet connection check via sockets i.e., it does not work any more:

## see if we can resolve the host name -- tells us if there is
## a DNS listening
host = socket.gethostbyname("http://google.com")
## connect to the host -- tells us if the host is actually reachable

s = socket.create_connection((host, 80), 2)
s.close()

Hey Fernando,

Personally, I've never used the urllib module before. 

https://stackoverflow.com/a/41431794

Looking at this stackoverflow, there is no urllib.request in Python 2. If you want to use the same library, it looks like you should be using urllib2. 

The code I posted should allow you use the same base code of the class, you need add a try/except and use a different import statement if it fails. 

try:    # For Python 3.0 and later    from urllib.request import urlopenexcept ImportError:    # Fall back to Python 2's urllib2    from urllib2 import urlopenhtml = urlopen("http://www.google.com/")print(html.read())

Sorry if this hasn't been helpful, but v5.81- uses Python 2 and therefore you need to handle the Python 2 vs 3 changes for your macros. 

Hi Bryce,

thanks, I noticed it already while testing the Beta version, which is great, thanks for fixing it.

The question is if there is anything similar for 5.81 and older as TBC cannot import urllib although the urllib.py exists on the corresponding folder.
