    How to expose Decorated Names of a DLL to COM?

    I can sucessfully expose functions of a DLL to COM, but in a specific application, it is expecting a decorated name
    Code:
    ?EuroScopePlugInInit@@YAXPAPAVCPlugIn@EuroScopePlugIn@@@Z
    How I can expose a decorated name? I currently have...
    Code:
    void EuroScopePlugInInit(out IntPtr Plugin);

      Hey, that works, thanks Alex! I only had to allocate the structure in memory. However I have a new problem... which I shall start a new thread... regarding callbacks and garbage colllection.

        Hehe you wouldn't believe how long it took to write. I hope its clear enough. I use a similar function without structures, that passes strings and numbers fine. Its just when I pass structures that it comes up with the Exception. Does it have something to do with the way the struct is Marshalled?

        Having made a test program to send an unmanaged struct to a c++ function, it works, but I am still confused as to why it doesnt work in the...

          Well this can be attacked in many different ways, but heres how I would do it;

          Have the function return 'const char*' instead of 'CString'

          CString theString( "This is a test" );
          char* mychar = new char[theString.GetLe ngth()+1];
          _tcscpy(mychar, theString);
          return mychar;

          then in C# use DLLImport to import the function which it will now return a normal C# string that is recognised...

            Those look like debug strings. Build -> Clean Solution. Ensure the Configuration is set to Release. Then Build -> Build Solution

              AccessViolationException - passing Structures between Unmanaged and Managed Code

              I have a problem trying to pass a structure to an unmanaged c++ DLL from C#. When I call PCSBSpecifyPilo tLogon from C#, it throws an AccessViolation Exception

              This is what I have...

              The exported C++ DLL Function;

              Code:
              __declspec(dllexport) void PCSBSpecifyATCLogon(PCSBSessionID, const char * inServer, unsigned short inPort, const char * inID, const char * inPassword, const PCSBATCConnection_t * inInfo);
              ...
