HWND hwndOwner,
| // Handle to owner window
| UINT cidl,
| // Number of objects specified in apidl
| LPCITEMIDLIST *apidl,
| // Pointer to an array of pointers to an ITEMIDLIST structure

Parameters
hwndOwner
Handle of the owner window that the client should specify if it displays a
dialog box or message box.
cidl
Number of file objects or subfolders specified by apidl.
apidl
Pointer to an array of pointers to ITEMIDLIST structures, each of which uniquely identifies a file object or subfolder
relative to the parent folder. Each item identifier list must contain exactly one SHITEMID structure followed by a terminating zero.
riid
Specifies the type and the interface of the COM object to return. This
parameter can be a pointer to the IID_IExtractIcon, IID_IContextMenu, IID_IDataObject,
or IID_IDropTarget interface identifier.
prgfInOut
Reserved.
ppvOut
Address that receives the interface pointer. If an error occurs, a NULL
pointer is returned in this address.
Return Values
Returns NOERROR if successful or an OLE-defined error value otherwise.
Remarks
GetUIObjectOf creates a UI object to be used for specified objects. Either IID_IDataObject
(transfer operations) or IID_IContextMenu (context menu operations) is passed
in the riid parameter.
