Arnon, Do you know of any reason why a dll written to work with VB, C++, and Delphi won't run with Foxpro. I have tried everything I can think of to get it to work, to no avail. The Regfn() for both dll functions returns a positive integer. The callfn() for the first registered function returns values, but the callfn() to the second does not. Any ideas....
