win95 (32 bit) thunk gpib.dll(16 bit to 32 bit) using Visual Basic

[mike6131]

I've tried to solve this problem a couple of times. I'm using Win95 (32 bit) and Visual Basic ver 5 (32 bit) with a gpib (PCIIA) with 16 bit drivers (NI-488.2 ver 2.6). I can't update the gpib drivers because other software (Instron) uses the old 16 bit drivers. I guess I need to thunk the dll's from 16 bit to 32 bit (gpib.dll, gpib-16.dll, gpib-32.dll). I'm not sure what the VB code is to thunk dll's and I still cannot load the library (gpib.dll) in my visual basic program. Thanks for your time and effort.

Try using "NI-488.2 (Win32) Version 1.20 for Windows 95/98 -- Compatibility Release Software". This kit provides GPIB-32.DLL thunk driver. The URL is below:

I still recommended to upgrade your NI-488.2 software to the true Win32 version of NI-488.2M that has capabilities to operate classic Win16 and DOS GPIB apps under Win9x.
