Here is a twist to the problem of a DLL hanging LabView. Our development group sent me a set of vi's that call C functions from a DLL. When I try to open the vi's LabView hangs. I had the vi's changed so the 'Specify path on diagram' was checked. This resolved the problem of the vi's opening. Only problem is they wouldn't run when downloaded to PXI target running LabView RT. Now for the interesting twist. I kept trying to run the vi's with the 'Specify path on diagram' box checked but I never had any luck getting them to run. I then went back to original vi's ('Specify path on diagram' not checked) and they would now load and not hang LabView. On top of that, they downloaded to the target and executed without any problems. My question is what could changed in Labview? I didn't change any options or any parameters in the .ini file. I am trying to run the same vi's on a second machine and I'm having the DLL hang problem on that machine. Again, I've compared .ini files and LabView options and there are no differences. Any ideas? Thanks!

DLL Hangs LabView

Hi

I have solved both my problems. thank you all for spending your time on my problem.

the problem was that : the dependency fiels were not found. I copied them and solved one problem.

the second problem was that dll was hanging because of my event structure! (i dnt realize it for 3 days!!)
