Question

I am working with an application in C# that need to send a message to a C++ application.

I imported

[DllImport("user32.dll")]
        public static extern IntPtr SendMessage(
              int hWnd,      // handle to destination window
              uint Msg,       // message
              IntPtr wParam,  // first message parameter
              IntPtr lParam   // second message parameter
              );

but now, my problem is that I need to passe string to wParam and lParam. I tried unsafe code, but it seems string just doesnt work like the rest of variables. How can I achieve that? Thanks.

We ended up using “WmCpyDta_d.dll” to deal with all that.
