EN_KILLFOCUS Overview  Group

The EN_KILLFOCUS notification message is sent when an edit control loses the keyboard focus. The parent window of the edit control receives this notification message through the WM_COMMAND message.

EN_KILLFOCUS 

idEditCtrl = (int) LOWORD(wParam); // identifier of edit control 

wNotifyCode = HIWORD(wParam);      // notification code 

hwndEditCtrl = (HWND) lParam;      // handle of edit control 

 

Remarks

In previous versions of Windows, the notification code was in HIWORD(lParam).
