I am baffled. I do have a VFP7 app that is installed on a machine that has no developer version of VFP, no source code, just the APP and the VFP 7 runtime. This app has PRG based classes that use the DEFINE CLASS ... OF ClassName with absolutely no extensions. The app works. Now, I also have no VCX classes with a name the same as any of the PRG classes. There are no error messages in my ErrorLog table either. This is a Word automation app, and those classes are used to create the Word docs. This technique is working great. I do not know what else to say.

>If I build an EXE and put no extenstion, the classlib is not found and the exe fails to run. If I use the FXP extension, the EXE runs fine. However, if I erase my FXPs in developement mode (as I do because I never want stale FXPs around with VSS and SOS), my DO FORM xyz fails because certain ClassLibs aren't automatically compiled. So the solution is to ensure my developement mode not only erases the FXPs, but recompiles the PRGs so I always have good FXPs around. Also, one must use the FXP or VCX extension in the OF clause.
