Console App Mouse-Click X Y Coordinate Detection/Comparison

After searching for a long time I finally found this example. Download the example program on the page. It gives you, among other things, the mouse location in the console window (character-based).

EDIT: This is my ConsoleListener class (with part of my NativeMethods class).
You can attach a handler to the MouseEvent (after calling the Start() method).

To make it work properly, you probably want to execute this code first:

IntPtr inHandle = GetStdHandle(STD_INPUT_HANDLE);
uint mode = 0;
GetConsoleMode(inHandle, ref mode);
mode &= ~ENABLE_QUICK_EDIT_MODE; //disable
mode |= ENABLE_WINDOW_INPUT; //enable (if you want)
mode |= ENABLE_MOUSE_INPUT; //enable
SetConsoleMode(inHandle, mode);
