LBSELCHSTRING message
[Starting with Windows Vista, the Open and Save As common dialog boxes have been superseded by the Common Item Dialog. We recommended that you use the Common Item Dialog API instead of these dialog boxes from the Common Dialog Box Library.]
An Open or Save As dialog box sends the LBSELCHSTRING registered message to your hook procedure when the selection changes in any of the list boxes or combo boxes of the dialog box.
#define LBSELCHSTRING TEXT("commdlg_LBSelChangedNotify")
