did somebody use Visual C++ for building DLLs which can be used from Origin with the dll command? I would be very much interested, since I ran into problems with my C++ compiler. A colleague coded it with Borland C++ and it works, but VC doesn't do the job. Somehow the names inside the DLL look different. Using "dumpbin /exports mydll.dll" reveals that there is a question mark inserted before the name of the exported functions and also one can find something like "@@YAKZ@DFN" appended. I am not a freak in Windows programming, so I don't know how to sail around this cliff... Did somebody meet such problems? Any hints and tricks are wellcome!

The Borland compilers have an option for turning this off. I am not aware of an option for VC. However, I suspect you are exporting your function with "__declspec( dllexport )" instead of a .DEF file. If your project does not have a .DEF file then adding one should solve your problem. The following is all you should need:

; simple DEF file
EXPORTS
ABELN

Once you have a DEF file you will no longer need "__declspec( dllexport )".
