Bill,

1. you can open the classlib as a table. Make sure SET DELETED = OFF. Multiple versions of the same class might be there. You might recover the code from there.
2. if you build a working exe from it, you might be able to recover from there.

ON KEY LABEL F9 SELECT * FROM MyClassLIB.VCX INTO DBF MyCopy.VCX
