I am trying to make calls to my new NI GPIB-PCI board using an application that was developed using MSVC++ 1.52 on a Windows 98 OS. Using MAX I can see the board and communication to instruments on the GPIB works fine but when I try to use my application it keeps telling me that it can't find the device. I think the problem is that the application can't find the GPIB board. I decided to rebuild the application using the new API but then I realized that the new API is for 32 bit environments. MSVC++ 1.52 is a 16 bit environments. Any ideas how I can make this happen? Thanks

Erich, Almost forgot, the 1.70 driver cannot be downloaded from the web site. You must request the driver using the Legacy NI-488.2 Driver Request form. While it is a bit of an inconvenience to get the 1.70 driver, it still might be worth it if you want to do GPIB Win16 applications on Windows 98. gpibtester

Solved!

Erich,

That is great news that you are able to use the 1.70 driver to work with your Win16 app on Windows 98 and that you won't have to spend any time rewriting the app to make it work as either a Win32 or DOS app!

And thank you again for your patience and help in getting to the root of the problem!
