true if the key was processed by the control; otherwise, false.
This method is called during message preprocessing to handle dialog characters, such as TAB, RETURN, ESC, 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 method, or returns false if the control has no parent. The Form class overrides this method to perform actual processing of dialog keys. This method is only called when the control is hosted in a Windows Forms application or as an ActiveX control.Notes to Inheritors:
When overriding the method in a derived class, a control should return true to indicate that it has processed the key. For keys that are not processed by the control, the result of calling the base class's ProcessDialogChar method should be returned. Controls will seldom, if ever, need to override this method.
