Answer 1

Point mouse_offset;

private void Form2_MouseDown(object sender, MouseEventArgs e)
{
mouse_offset = new Point(-e.X, -e.Y);
}

private void Form2_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
Point mousePos = Control.MousePosition;
mousePos.Offset(mouse_offset.X, mouse_offset.Y);
Location = mousePos;
}
}
