SHBindToParent, get a parent pidl

Question

I'm implementing Windows-Explorer-view-like.

First i get desktop pidl via SHGetSpecialFolderLocation(NULL, CSIDL_DESKTOP, &pidl) and store it in class atribute. After my IShellBrowser::BrowseObject get called, i overwite the atribute with pidl is passed via this method. If i want to go up, i call call SHBindToParent, pass the stored pidl to it, but i got either E_INVALIDARG or desktop pidl. I suspect that i pass wrong PIDL in it.

How should i get parent PIDL right?

Um, `IShellBrowser::BrowseObject` takes a relative pidl, but `SHBindToParent` takes an absolute pidl. — Raymond Chen, Jun 25 '12 at 16:29

// C#
 [System.Runtime.InteropServices.DllImportAttribute("shell32.dll", EntryPoint="ILRemoveLastID")]
    [return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
public static extern  bool ILRemoveLastID(System.IntPtr pidl) ;

}
