Error closing LabVIEW 6.0 program with DLLs

[Dermot1000]

Hi all,
I have a program in LabVIEW 6.0.2 that uses DLLs to control a Laser Extensometer. Since I put the DLLs in the code, LabVIEW crashes most of the time when closing LabVIEW (LabVIEW.exe has generated errors and will be closed. Restart application).
What could that be?
Greetings Dermot

Hi Dermot,

I can only assume that you are using the "Call Library Function", right?

Check your parameters versus their types (ie: are you using pointers, is it the appropriate type or format, etc). Also check the calling convention (C or stdcall).

Sometimes the smallest oversight creates the biggest headaches.

Cheers,
