Hi Bob,

thanks for the reply!
The application code is shown below. the exception is cached by 
try/catch statement. all necessary error handling is done - no errors in 
linking of dll. The function pointer (DLL offset) is correct. Other 
(tested) functions of dll are fine.

In MSVC code VCL objects are exchanged for MFC, nothing else changed.
Regards,
Boris

.cpp:

     else

        Memo1->Lines->Add(AnsiString().sprintf("Task '%s' is beeng 
loaded...", Edit1->Text.c_str()));
