CBN_CLOSEUP

CBN_CLOSEUP

idComboBox = LOWORD(wParam);

hwndComboBox = (HWND)lParam;

The CBN_CLOSEUP notification message is sent when the list box of a combo box is hidden. The control's parent window receives this notification message through a WM_COMMAND message.

Parameters

idComboBox

Value of low word of wParam. Specifies the combo-box ID.

hwndComboBox

Value of lParam. Specifies the combo-box window handle.

Comments

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

An application should not make assumptions about the order in which notifications are sent. In particular, a CBN_SELCHANGE notification may occur either before or after a CBN_CLOSEUP notification.
