CBN_EDITUPDATE

The CBN_EDITUPDATE notification message is sent when the edit control portion of a combo box is about to display altered text. This notification message is sent after the control has formatted the text, but before it displays the text. The parent window of the combo box receives this notification message through the WM_COMMAND message.

CBN_EDITUPDATE 
idComboBox = (int) LOWORD(wParam);  // identifier of combo box 
hwndComboBox = (HWND) lParam;       // handle to combo box 
 

Remarks

If the combo box has the CBS_DROPDOWNLIST style, this notification message does not occur.
