How do I get UI text from external app in C#.

public static extern int SendMessage (IntPtr hWnd, int msg, int Param, System.Text.StringBuilder text);

System.Text.StringBuilder text = new System.Text.StringBuilder(255) ;  // or length from call with GETTEXTLENGTH
int RetVal = Win32.SendMessage( hWnd , WM_GETTEXT, text.Capacity, text);
