CDM_GETFOLDERIDLIST 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[Starting with Windows Vista, the Open and Save As common dialog boxes have been superseded by the Common Item Dialog.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 address of the item identifier list corresponding to the folder that an Explorer-style Open or Save As dialog box currently has open. 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_GETFOLDERIDLIST (CDM_FIRST + 0x0003)
Parameters
-
wParam
-
The size, in bytes, of the lParam buffer.
-
lParam
-
A pointer to the buffer that receives the list of item identifiers.
Return value
If the message succeeds, the return value is the size, in bytes, of the list of item identifiers. This is either the number of bytes 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_GetFolderIDList(hwnd, lparam, wparam);
