I believe I included the source code to the comparison utilities in the downloads that I sent to you earlier. The comparison tools allows comparisons of PRG, VCX, SCX, DBC, and DBF. The VCX tool allows comparison of VCX to VCX or class to class (within a single VCX).

If you do not have it, please reply and I will send you a link to download the project. Note that the project relies on CodeMax and BBListView active-x components.
