WinForms - How to call the Window Documents Context Menu

Question

On every windows app there is that context menu that you can access with CTRL+Space bar:

I believe this menu is called the "Window Control Menu", but I am not sure.

It has the following options:

• Restore

• Move

• Size

• Minimize

• Maximize

• Close Alt+F4

Here is a pic:

How can I call this using win forms? My goal is to provide a keyboard shortcut to this menu by hitting alt+spacebar

Thanks.

Send a message to your own window so that the system menu appears.

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, int lParam);

    private void callSysMenu()
    {
        int point = ((this.Location.Y << 16) | ((this.Location.X) & 0xffff));
        SendMessage(this.Handle, 0x313, IntPtr.Zero, point);
    }
