Hi all,

I figured my own problem out.

I did this:

Public Class MyTextBox
   Inherits TextBox

   Private Const WM_COPY = &H301
   Private Const WM_PASTE = &H302
   Private Const WM_CUT = &H300
   Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)

       'Stop the control from excepting paste commands
       If m.Msg = WM_PASTE Then
           Dim txt As String =
Clipboard.GetDataObject().GetData(GetType(String))

           Return
       End If

       MyBase.WndProc(m)

   End Sub

End Class

This works fine, do you have to always do it this way to add functionality
to the control? Can't you just entercept the
message from the form where the control is located?

One more thing how can I change the selected text color  in a textbox?

Thanks
Gerry
