CDN_SELCHANGE notification code

[Starting with Windows Vista, the Open and Save As common dialog boxes have been superseded by the Common Item Dialog.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.]

Sent by an Explorer-style Open or Save As dialog box when the selection changes in the list box that displays the contents of the currently opened folder or directory.

Your OFNHookProc hook procedure receives this message in the form of a WM_NOTIFY message.

#define CDN_SELCHANGE           (CDN_FIRST - 0x0001)
#define CDN_FIRST               (0U-601U)

Parameters

wParam

This parameter is not used.

lParam

A pointer to an OFNOTIFY structure. The OFNOTIFY structure contains an NMHDR structure whose code member indicates the CDN_SELCHANGE notification message.

Return value

The return value is ignored.

Remarks

The system sends this notification only if the dialog box was created using the OFN_EXPLORER value.

To get the name of the newly selected file or folder, the hook procedure can send the CDM_GETFILEPATH or CDM_GETSPEC message to the dialog box.
