CDM_GETFOLDERIDLIST
[New
- Windows NT]
The CDM_GETFOLDERIDLIST
message retrieves the address of the item identifier list corresponding to the
folder that an Explorer-style Open or Save As common dialog box currently has
open. The dialog box must have been created with the OFN_EXPLORER flag;
otherwise, the message fails.

lParam = (LPARAM) (LPVOID) pidl;
// Corresponding macro
int CommDlg_OpenSave_GetFolderIDList(hdlg, pidl,
cbmax);
Parameters
hdlg
Handle of the
common dialog box window to receive the message.
pidl
Pointer to
the buffer that receives the list of item identifiers.
cbmax
Size, in
bytes, of the pidl buffer.
Return Values
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 pidl
buffer, or the required buffer size if the buffer is too small.

occurs, the return value is less than zero.
