Hello,

I have a function in a native DLL declared as follows:

__declspec(dllexport)  int  Start( char* Key );

And the declaration in my C# class is as follows:

[DllImport("SockSp10.dll")]
public static extern int Start([MarshalAs(UnmanagedType.LPStr)] string Key);

Yet when I call the function from my C# class, I receive, "Unable to find an
entry point named Start in DLL XXXX"

Does this error message indicate a problem with the calling convention?  the
parameter list? the return type?

I am able to use this DLL with no problems from an MFC application, so I
know the functions are being exported correctly.

Thank you for any pointers,
Rich
