Wow Judy. Did the wrapper work yet? I saw your question and just wanted to make sure you have read the following article:

Nice url huh. Anyway, it's just about the wizards used to create instrument drivers for VC++. I thought this would be useful for you but after reading your question the chances look slim at best. Anyway, maybe it will help to know that people really are reading your questions even though we might not have anything useful to say.
