CBN_CLOSEUP Overview  Group

The CBN_CLOSEUP notification message is sent when the list box of a combo box has been closed. The parent window of the combo box receives this notification message through the WM_COMMAND message.

CBN_CLOSEUP 

idComboBox = (int) LOWORD(wParam);  // identifier of combo box 

hwndComboBox = (HWND) lParam;       // handle of combo box 

 

Remarks

This notification message is not sent to a combo box that has the CBS_SIMPLE style.

In general, you cannot predict the order in which notifications will be sent. In particular, a CBN_SELCHANGE notification message may occur either before or after a CBN_CLOSEUP notification message.
