This method is called during message preprocessing to handle dialog box keys, such as TAB, RETURN, ESCAPE, and arrow keys. This method is called only if the IsInputKey method indicates that the control is not processing the key. The simply sends the character to the parent's Control.ProcessDialogKey method, or returns false if the control has no parent. The Form class overrides this method to perform actual processing of dialog box keys. This method is only called when the control is hosted in a Windows Forms application or as an ActiveX control.
