I recently learned that you can ship COM as either an .EXE or a .DLL (nobody has yet let me know why). You don't have a traditional .DLL that you would use ctypes to call methods in, you have a COM .DLL. COM methods need to be access with Win32com obj=win32com.client.Dispatch("typelib name"). You need to find out the COM dispatch typelib name and make sure the DLL is registered (regsvr32 your.dll). -Larry -- http://mail.python.org/mailman/listinfo/python-list
