Answer 1

private void Form1_MouseDown(object sender, MouseEventArgs e) { mouse_offset = e.Location; } private void Form1_MouseMove(object sender, MouseEventArgs e) { if (e.Button == System.Windows.Forms.MouseButtons.Left) { Point mousePos = Control.MousePosition; mousePos.Offset(mouse_offset); this.Location = mousePos; } }
