ibrd crashing application and VisualBasic compiler

[cgantz2000]

I wrote an application to control several instruments in VB6. I have XP and a PCM-CIA Gpib card.

The application will read correctly for about 50 cycles, then stops, locking up not only the application, but the VisualBasic compiler. Running a stand-alone version also crashes (just itself, obviously not the VB compiler.

Any ideas.

What version of NI-488.2 are you using? Does this lock up the entire system as well? Does the crash reference any address location in a specific component?

Hi Craig,

It looks like 2.1.0.3158. That's what I get when I do properties on the gpib-32.dll file in System32

Sorry Craig,

I only answered one of your questions.

The crash does not effect the system. Only the application and the VisualStudio ide are effected. I can stop the program by clicking on the close icon at the top right of the form. When I do this, I get the message that the application is not responding, and do I want to close it. When I say yes, both the application and the Visual Studio ide are closed. Also, when the application freezes, so does Visual Studio. I have never seen this before, since the VisualStudio debugger is supposed to prevent this.

Also, I don't get any error messages.
