If I understand your question correctly, you should include your forms in the same EXE as the VCX where your "Do Form..." method is located.

>I have an exe with nothing but classlibs in it (myLibraries.exe)
>I have another exe with no classlibs in it (myMain.exe). It has "set classlib to myClasses in myLibraries.exe".
>
>A class inside myLibraries.exe does a "Do Form ....."
>During Runtime:
>When I run myMain.exe,
>If the form is not in myLibraries.exe, I get an error "...scx does not exist", even though it's inside myMain.exe.
>
>The classes in myLibraries call prgs that are not inside myLibraries.exe and they are found (although they are in a procedure file file with "set procedure" inside myMain.exe).
