How do you prevent a windows from being moved?

Question

How would i go about stopping a form from being moved. I have the form border style set as FixedSingle and would like to keep it this way because it looks good in vista :)

Answer 1

Private Sub MyFormLock() Me.Location = New Point(0, 0) End Sub

Private Sub SearchSDR_LocationChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LocationChanged
    Call MyFormLock()
End Sub

Try to override WndProc:

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);
}

I found this to stop the form from moving (its in c#)

protected override void WndProc(ref Message m)
        {
            const int WM_SYSCOMMAND = 0x0112;
            const int SC_MOVE = 0xF010;

            switch (m.Msg)
            {
                case WM_SYSCOMMAND:
                    int command = m.WParam.ToInt32() & 0xfff0;
                    if (command == SC_MOVE)
                        return;
                    break;
            }
            base.WndProc(ref m);
        }

Answer 4

change the Form property StartPostion to Manual. Then, handle the LocationChanged event:

private void frmMain_LocationChanged(object sender, EventArgs e)
{
Location = new Point(0, 0);
}

Answer 5

You can try:

this.Locked = true;

Answer 6

In Windows, the WS_CAPTION style is the non-client area that allows your window to be moved with a mouse. So the easiest way to do what you want is to remove this style from your window.

However, if you need to have a caption and still achieve what you want, then the next style would be to capture the WM_NCHITTEST message and check for HTCAPTION. If the code is HTCAPTION, return NTNOWHERE instead. This will prevent the default window procedure from executing the default move window thing.
