Thanks so much for that explanation. Now, before I put fingers to keyboard with what I have, on a 64 bit machine, when I covert to 32 bit Office, will I be able to convert what I have , or are we talking rewrite. I just checked the web and there are a lot of hits on how to convert 32 bit Office apps to 64 bit Office, but not the other way. However, I just watched a video by Richard Rost, who says that ACCESS will run on either 32 or 64 bit Office, if you don't have Active X controls or API calls, the app will run on both versions of Windows. The app I am creating uses neither, and is dirt simple. There is minimal data, and everything is self contained in the app, except for Word documents. Do you agree with that?
