I believe you'll have to do this the old way, using GetSystemMenu and
AppendMenu or InsertMenuItem API Calls, then overide WndProc for the
messages. The following is a very basic VB.Net example:
<DllImport("user32", CallingConvention:=CallingConvention.Cdecl)> _
Private Shared Function GetSystemMenu( _
ByVal hwnd As IntPtr, _
ByVal bRevert As Boolean) As IntPtr
End Function
<DllImport("user32", CallingConvention:=CallingConvention.Cdecl)> _
Private Shared Function AppendMenu( _
ByVal hMenu As IntPtr, _
ByVal uFlags As Integer, _
ByVal uIDNewItem As Integer, _
ByVal lpNewItem As String) As Boolean
End Function
Private Const WM_SYSCOMMAND As Integer = &H112
Private Const MF_SEPARATOR As Integer = &H800&
Private Const MyMenuItemID As Integer = 1001
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
MyBase.WndProc(m)
If m.Msg = WM_SYSCOMMAND Then
If m.WParam.ToInt32 = MyMenuItemID Then
MessageBox.Show("MyMenuItem Clicked", "System Menu")
End If
End If
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
_
Handles MyBase.Load
Dim SysMenu As IntPtr = GetSystemMenu(Me.Handle, False)
AppendMenu(SysMenu, MF_SEPARATOR, 0, Nothing)
AppendMenu(SysMenu, 0, MyMenuItemID, "MyNewItem")
End Sub
