If you have already created your classes, the _INCLUDE system variable won't work because it is not retroactive. It will work on newly created classes. To retrofit your existing classes, do the following:

1. Open your VCXs as a table (i.e. use myclasslib.vcx alias insrc)
2. Execute the following SQL statement: update incsrc set reserved8 = "MyIncludeFile.H" where !empty(class) and !empty(baseclass)
3. Close the VCX.
4. Compile the VCX (compile classlib myclasslib all)

You should be good to go.

HTH.

FWIW, I will be posting a utility that does this for class libraries, forms and menus in a specified directory today sometime.
