This should be simple, but I am stuck.

I have a SDI application which has a winToolbar which has a menu with cut, copy, and paste (with associated shortcuts).

The interface always has two controls visible at any time.  The control on the right is mostly infragistics textbox controls and a few QWhale editor controls.  The control on the left changes based on user selection, but is also primarly infragistics textbox controls but also includes grid controls, checkboxes, radio buttons, etc.

How do I add cut, copy, and past support for the textbox, grid, and QWhale controls?  When the keyboard is called, the menubar should trap it and I should be able to tell which control made the call (hopefully, though it's not working now), but if the menu item is clicked, how do I determine which control last had the focus (does my main form have to track this with an object)?

FYI, this code did not work:

                    If TypeOf ActiveControl Is TextBoxBase Then
                        CType(ActiveControl, TextBoxBase).Paste()
                    End If

Thanks,

Andrew
