PCI-GPIB Card with Visual Basic gives blue screen and re-boots PC

[tonyg]

The application makes the "ibsic" call then "ibln" to find devices on the bus. Running the VB program the first time is fine, but if you end the program and re-run a second time, you get a blue screen and the PC reboots when the program reaches the lines that make the first call to the NI-488 functions. If you close out of VB and then restart VB, everything is OK again.

What is wrong?

Hi,

Here's an article that describes the most common blue screen when using VB:

Hope this helps
