I did see this error before, i had a program class set to OLEPUBLIC with the same name as a constant if i remember well.

In the Prg:

Define Class MyClass As Session OlePublic

And somewhere else in a .h file

#DEFINE MyClass 1

>That other thread spent most messages talking about compile errors and such. In this case, there are no compiler errors and I can BUILD APP and have it build an APP. But if I try to build EXE or either type of DLL I get the error 11 that I mention above.

>This executable is a COM executable that utilizes a lot of other objects (ADO, Pegasus imaging controls, etc.) Would not having a certain COM object registered on my system cause this type of error? I have no way of knowing what components are built into the executable (I need something like VB's component viewer for the project). How can I tell what I am missing or what is causing the error? Surely, even if I am missing something I shouldn't get a flat-out run-time error while compiling? Is this a bug? Again, this is VFP 7.0 SP1 (Build 9465) running on Windows XP.
