|The error message is telling you the reason. The DLL created in VC6 is not a .NET assembly.
If you want to use it in your project, you will have to use P/Invoke.
Since this is the C++/CLI forum, I forgot to mention that you can also call the DLL functions directly from C++. But there is no way to add it as a .NET reference.
The difficult we do right away...
...the impossible takes slightly longer.
