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[Starting with Windows Vista, the Open and Save As common dialog boxes have been superseded by the Common Item Dialog.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

Sets the default file name extension for an Explorer-style Open or Save As dialog box. The dialog box must have been created with the OFN_EXPLORER flag; otherwise, the message fails.

#define CDM_FIRST               (WM_USER + 100)
#define CDM_SETDEFEXT           (CDM_FIRST + 0x0006)
