labwindows 2013 not responding

Solved!
Go to solution

I am using Labwindows 2013 SP1 on Windows 7

 

This morning I made some code changes to my project when I clicked on the "Debug Project" Icon, the project build succeeded and then Labwindows just hangs up, saying "Not Responding". I killed the project and relaunched labwindows and tried again and it does the same thing. I backed off all changes I did today to what it was yesterday when I did not have this problem and tried again and it is still hanging with "not responding".

 

I went to labwindows 2013 about 4 months ago and I have never had this problem until today and now it wont go away.

 

I am completely at a standstill. Can anyone help me fix this problem?

 

Thanks

John W.

Try going into Start Menu -> Control Panel -> Programs and select National Instruments Software and do a Repair

Hi, John—

 

Can you provide a LabWindows/CVI log for this behavior? Please follow the steps under the Environment section of this article: https://decibel.ni.com/content/people/nickb/blog/2010/08/02/generating-debug-logs-for-labwindowscvi-... .

 

Did you try repairing LabWindows/CVI? If so, what was the outcome?

 

Thanks,

Thanks for the response.

I did a repair, and same thing happens when I try and run. The project builds and then just hangs saying (Not Responding) at the top. I click the x to close the session, windows says it's not responding and then I clcik close program.

 

I tried to attach the CVIDebugLog.txt file that you requested but it is too large. It is over 10 meg and the limit to attach a file says 6 meg . Please let me know what I need to do next.

 

Thanks!

John W.

Hi, John,

Can you name the file something obvious and upload it to ftp://ftp.ni.com/incoming ?

Thanks for the response.

 

I just put the debug file up on the NI FTP site;

The file name is:

Thanks!

Hi, John.

 

The log you sent in seems to indicate you have over 750 watch expressions in your current workspace. This hang you are experiencing is likely a result of LabWindows/CVI attempting to update all of those watch expressions. 

 

I reproduced a considerable hang by adding only 700 watch expressions, all for a single int value in my application. 

To fix this issue, you can remove the watch expressions. If you cannot access them interactively from the LabWindows/CVI environment, you can delete them from the bottom of your CWS file. You can do this in a text editor.

 

Let me know if this works for you.


Thanks,

Wow, I went into the .cws file and there were over 2000 watch expressions!

 

I deleted them like you said and now the project builds and launches fine.

 

Not quite sure how I got that many watch expressions but I will be more careful in the future.

 

Thank you very much for your help!
