I am using LabVIEW 2011 SP1.
I have a number of vi's that are exported in a dll and a CVI SFP which i am using to interface to this dll. I am intermittently getting a popup detailing Internal Warning 0xB7C5F12E AppInit.cpp line 250 LabVIEW Version 11.0.1.
Has anyone seen this error before?
I have also seen another issue when i sometimes get a small popup detailing 'Reseting Main.vi'.
You're probably going to have to share a bit of your code to get this figured out. The Resetting Main popup is when a VI is forced to exit when it wasn't ready. This can be caused by a hard VI stop or a VI loaded by reference that doesn't finish before you try to exit.
I do not know WinDev, but the DLL created with LV particularly are sensitive to the threads used to activate them.
Try to force the thread to avoid the UI thread
Program the VI reentrant, it will launch a new instance in case the first is not completely closed.
