Thanks for answering. I don't have a specific project in mind, just looking for a templet to build on. Your example is perfect, a small app written in VB to read and write to a pic's ports and modules.

I worry a little, starting projects based on VB6, mister-e and DT's great work. Some of this material is 10 years old now and they are no longer here to answer or modify these routines.

Found this site which sells a DLL for Visual Studio that looks very interesting. It can be used with VS 2015 and examples in MikroC. I have Mikrobasic so this may be the best path. The only reason I have not purchased it, the examples and videos are not in English, so I need a little more time to study.
