I have used C++ DLLs ( with user interface ). I sent a task, as a string to the DLL and periodicaly checked for acknoledge from the DLL. so i had 2 function within the DDL: SETTASK and GETACK.
this worked fine with FPW but crush with VFP3.0
my next step is to upgrade from VC++ 1.52 we are using to VC++ 2.0 witch is 32 bit version.
