I got a requirement about the pop-up block staff. It is said in MSDN that
developer can implement INewWindowManager interface to handle the case under
your own rules(you can override some or all of the Microsoft Internet
Explorer pop-up blocking logic).
   After installing the XP SP2 SDK, I found the definition of
INewWindowManager in shobjidl.h (which is said to be "shlobj.h" in
documentation), but I could not found the guid of it in registry or by OLE
Viewer.
   I have made some sample codes, how the implemented EvaluateNewWindow
method is not called when new window is popped up(also IDocHostUIHandler is
implemented in the same class). Can anyone help me out?

   Your reply will be great appreciated, :).
   My codes are enclosed below.

    [ComVisible(false), ComImportAttribute()]
    [GuidAttribute("D2BC4C84-3F72-4a52-A604-7BCBF3982CBB")]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    public interface INewWindowManager
    {
        [PreserveSig()]
        void EvaluateNewWindow(String strUrl, String strName, String
strUrlContext, String strFeatures, bool fReplace, Int32 nFlags);
    }
