Remarks The deletion performed by the WM_CLEAR message can be undone by sending the edit control an EM_UNDO message. To delete the current selection and place the deleted content on the clipboard, use the WM_CUT message. When sent to a combo box, the WM_CLEAR message is handled by its edit control. This message has no effect when sent to a combo box with the CBS_DROPDOWNLIST style. See Also EM_UNDO, WM_COPY, WM_CUT, WM_PASTE |
