use visa32.dll for vba

[RaymondCheung]

I want to use visa32.dll in VBA to build some test routines for com port access. How can I make visa32.dll to work with VBA? Where can I find the files for the visa32.dll reference (or declaration)?

Hi Raymond,

You can refer to the NI-VISA Help installed with the driver for function information.  There is an entry in the help file called Function Reference which should contain all the information that you are looking for.

Hi Raymond,

If you are not familiar with calling .dlls in VBA, you may want to start with the MSDN Article: Calling DLL Functions in Microsoft Office.
