>Hi Mace:
>No, I'm not familiar with that technique or how to "compile the class libs." (How DO you compile the class lib only?) I only see VCX's and VCT's in my development directory. If I replace the methods in the VCX's with "", where do the method code come from? Help me understand this. Is there supposed to be the equivalent of an MPR from an MNX or FXP from PRG somewhere?

Only empty the Method field of the VCX copy you are providing to the customer. Make a copy of both the VCX and VCT files. Then you just open the VCX like a table, USE MyClass.VCX to replace all the Method fields with "".

All VFP versions, COMPILE FORM MyClass.VCX. In VFP 6 you can issue COMPILE CLASS MyClass.
