This article explains the usage of key and mouse events. The following code shows you how you can read mouse position on mouse move.
The MouseEventArgs's X and Y member contains x and y mouse positions.
private void OnMouseMoveEvent(object sender,MouseEventArgs e)
{
//Application.Exit();
if (ixStart == 0 && iyStart == 0)
{
ixStart = e.X;
iyStart = e.Y;
}
else if (e.X != ixStart || e.Y != iyStart)
Application.Exit();
}
// This Article is a simple one to show the usage of KeyEvent and MouseEvent.
// Please move the mouse or press a key to Exit this Program.
