call library function

[b_lee]

I am using the call library function in a very simple VI. I have simple case structure that has different call functions to choose from. For some reason, after i run the anyone of the cases LabView shuts down completely. The commands are sent out fine but I have to restart LabView after every command. Any idea as to why this is and how i could stop it?

More than likely it's the DLL. Can you verify that the DLL works properly without crashing from another programming environment, like C? I would also check the calling convention you're using.
