How to add cut, copy and paste easy

Answer:

After a lot of hair pulling out I stumbled across this method of using the windows 
messages. This is best demonstrated with the following code: 

1   procedure TForm1.Cut1Click(Sender: TObject);
2   begin
3     SendMessage(ActiveControl.Handle, WM_Cut, 0, 0);
4   end;
5   
6   procedure TForm1.Copy1Click(Sender: TObject);
7   begin
8     SendMessage(ActiveControl.Handle, WM_Copy, 0, 0);
9   end;
10  
11  procedure TForm1.Paste1Click(Sender: TObject);
12  begin
13    SendMessage(ActiveControl.Handle, WM_Paste, 0, 0);
14  end;


If you are developing a MDI application, you will need to make sure that the 
message is sent to the active child by using: ActiveMDIChild.ActiveControl.Handle
