Yes I see your point.

Compiling for every customer might be a good idea.  If I had a "good copy"
of the VB6 project, and only changed one line for the serial number, then
compiled it for that customer, this might be the best way.  I may be able to
automate the line change and compiling, to make things quicker.

Thanks Ken! :)

On a side note, do you know if it's possible to do a "response.end" in a
ActiveX DLL?  I can get response.write and everything else working, but
response.end doesn't seem to "end" the script processing, and it continues
