Lock window position

You can override the WndProc method of the form to prevent it from moving. Here is the code.

protected override void WndProc(ref Message m)

{

    const int WM_NCLBUTTONDOWN = 161;

    const int WM_SYSCOMMAND = 274;

    const int HTCAPTION = 2;

    const int SC_MOVE = 61456;

    if ((m.Msg == WM_SYSCOMMAND) && (m.WParam.ToInt32() == SC_MOVE))
    {

        return;

    }

    if ((m.Msg == WM_NCLBUTTONDOWN) && (m.WParam.ToInt32() == HTCAPTION))

    {

        return;

    }

    base.WndProc(ref m);

}
