Hanging Program CVI

[Joe09]

Hi,

I'm using a CVI 8.0 program  for test a product. It was working well, but now there is not appearing some indicators (LED) in the user interface. I compile again the project, but it didn't work, the problem continues. I verified the program with windows task manager, and the program.exe comsumes 97-99% of the CPU. Is that normal?, because I think it's a lot percentage. I think the program.exe is hanging up the computer.

I investigate and found that to avoid system hangs up in LabVIEW, must be added 1 ms delay inside each while cycle. Is there any similar condition for LabWindow/CVI 8.0? can someone gime some suggestion I'll be grateful.

Hi Joe,

Any tight loops that you have in your code, you should be making calls to ProcessSystemEvents.  Refer to the Improving Performance of LabWindows/CVI Applications KnowledgeBase for other tips.

Let me know if this helps!
