This example uses an edit box, a rich edit control, and a button on a form. When the user clicks the button, text is cut from the rich edit control and pasted into the edit box.  Note that only the text is pasted. If the rich edit control includes any formatting information that is not pasted into the edit control.  If the destination where a rich edit control, the formatting information would be copied as well.

  RichEdit1->SelectAll();  
  RichEdit1->CutToClipboard();
