Re: call a COM DLL from C# application

Harish,

I'm assuming that one of the dlls is a native COM dll. The other dll is
the interop dll, and you need both to run your app. You will have to have
the original DLL registered (or not, if you are using no-reg COM) and then
the interop dll for your .NET code to use.
