No problems occurred in BCB 1.0 but BCB 3.0 gives the following error while running: "Project raised exception class EOleSysError with message 'CoInitialize has not been called.' " This problem even occurrs when using the ActiveX delivered with BCB 3.0. Answer: Try the following: - Add '#include' at the top of you application's main .CPP file (the one with WinMain) - Declare a global instance of the TInitOle class: #include TInitOle initOle; 7/2/98 10:32:32 AM
