You can use the SetCursorPos Api function. It accepts two parameters. These are the x position and the y position in screen pixel coordinates. You can get the size of the screen by calling GetSystemMetrics function with the correct constants. This example puts the mouse cursor in the top left hand corner. t& = SetCursorPos(0,0) This will only work if the formula has bee declared in the declarations section: Declare Function SetCursorPosition& Lib "user32" _ (ByVal x as long, ByVal y as long)
