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[Starting with Windows Vista, the Open and Save As common dialog boxes have been superseded by the Common Item Dialog.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

Retrieves the path of the currently open folder or directory 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 WM_USER                  0x0400
#define CDM_FIRST               (WM_USER + 100)
#define CDM_GETFOLDERPATH       (CDM_FIRST + 0x0002)

Parameters

wParam

The size, in characters, of the lParam buffer.

lParam

A pointer to the buffer that receives the path.

Return value

If the message succeeds, the return value is the size, in characters, of the path string, including the terminating null character. This is either the number of bytes or characters copied to the buffer, or the required buffer size if the buffer is too small.

If an error occurs, the return value is less than zero.

Remarks

The corresponding macro is as follows:

int CommDlg_OpenSave_GetFolderPath(hwnd, lparam, wparam);
