Hi Alex, thanks for your response, but I have to be more precise:
I do have the total developper suite installed on my computer, but:
The LABVIEW examples work perfekt with the IVI- drivers, the CVI- examples do it as well,
but: the VB examples do not!
Checking the configuration always shows the error message mentioned above. (BFFA002E )
So meanwhile I have a slight guess, that VB is not as much supported as LABVIEW resp. CVI.
Do you have any idea?
