How do I prevent the context menu from showing up on certain keyboard keys (like Keys.Apps)?

Platform: WinForms| Category: Menus

Override WndProc in your Control and do the following. You should then listen to keyup and show the context menu yourself.


[C#]
protected override void WndProc(ref Message m)
{
	if(m.Msg == 0x7b /*WM_CONTEXTMENU*/ )
	{
		return;
	}
	if(m.Msg == 0x101 /*WM_KEYUP*/)
	{
		Keys keys = (Keys)m.WParam.ToInt32();
		// Prevent this key from being processed.
		if(keys == Keys.Apps)
			return;
	}
	base.WndProc(ref m);
}

[VB.Net]
Protected Overrides  Sub WndProc(ByRef m As Message)
	If m.Msg = 0x7b Then ’WM_CONTEXTMENU
		Return
	End If
	If m.Msg = 0x101 Then ’WM_KEYUP
		Dim keys As Keys = CType(m.WParam.ToInt32(), Keys)
		’ Prevent this key from being processed.
		If keys = Keys.Apps Then
			Return
		End If
	End If
	MyBase.WndProc( m)
End Sub
