Many thanks for all the insight. I may just go back to Delphi to do
this as a DLL ... The VB.Net program has about a year's worth of code
now and so it's too late to go back. I assume Delphi can do all that
C++ Builder can do. I was a devoted Delphi programmer until about 3
years ago, but my clients could not accept Delpi. Again many thanks.

Will.
