Hello USBDude,
I am not sure if you are asking about examples for Visual Studio .NET or LabVIEW. We do have at least one example of GPIB usage in C#. Head over to www.ni.com/downloads and look for the example programs link. You should be able to find the examples there. You can also find GPIB examples for LabVIEW in the example programs section as well as included with your installation.
