Answer 1

Have you added :

this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.frmMain_FormClosing);

(automatically added when you double-click in the Designer)

Answer 2

Try the following

Paste into form

const int WM_CONTEXTMENU = 0x007B;  
protected override void WndProc(ref Message m)  
{  
    if (m.Msg == WM_CONTEXTMENU)  
    {  
        m.Result = IntPtr.Zero;  
        Close();  
    }  
    else  
    {  
        base.WndProc(ref m);  
    }  
}  

In the form constructor

Type Closing += press TAB which should give you an event e.g. where I added a MessageBox

Once you have right clicked the MessageBox is shown then the form closes.
