X_Coordinate = e.X;
Y_Coordinate = e.Y;
Mouse_Cord_Stored = true;
break;
}
case true:
{
//Move the Form using ActiveForm.Location if mouse coordinates are stored
Form1.ActiveForm.Location =
new Point(Form1.ActiveForm.Location.X + e.X - X_Coordinate,
Form1.ActiveForm.Location.Y + e.Y - Y_Coordinate);
break;
}
}

{
switch (Mouse_Cord_Stored)
