The CDN_SELCHANGE notification message is 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.

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.
