The Win32 API provides no direct method for obtaining the
window handle associated with a console application. However, you can
obtain the window handle by calling FindWindow(). This function retrieves a
window handle based on a class name or window name. Call GetConsoleTitle() to determine the
current console title. Then supply the current console title to FindWindow().
Because multiple windows may have the same title, you should change
the current console window title to a unique title. This will help prevent the
wrong window handle from being returned.

Function GetConsoleHwnd:hWnd;
Const Title='unique_title'#0;
Var hwndFound:hWnd;
   Sleep(40);             { <- let Windows update the title }
