CDN_FOLDERCHANGE

The CDN_FOLDERCHANGE notification message is sent by an Explorer-style Open or Save As common dialog box when a new folder is opened. Your OFNHookProc hook procedure receives this message in the form of a WM_NOTIFY message.

CDN_FOLDERCHANGE 
lpon = (LPOFNOTIFY) lParam; 
 

Parameters

lpon

Pointer to an OFNOTIFY structure.

The OFNOTIFY structure contains an NMHDR structure whose code member indicates the CDN_FOLDERCHANGE notification code.

Return Values

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 path of the newly opened folder, the hook procedure can send the CDM_GETFOLDERPATH message to the dialog box.
