The CBN_EDITCHANGE notification message is sent after the user has taken an action that may have altered the text in the edit control portion of a combo box. Unlike the CBN_EDITUPDATE notification message, this notification message is sent after Windows updates the screen. The parent window of the combo box receives this notification message through the WM_COMMAND message.
CBN_EDITCHANGE
idComboBox = (int) LOWORD(wParam); // identifier of combo box
hwndComboBox = (HWND)lParam; // handle of combo box
Remarks
If the combo box has the CBS_DROPDOWNLIST style, this notification message does not occur.
