QuestionIoleUndoManager with Excel application Pin

Hi all,
First of all, I would like to apologize for posting this question in the C++ forum as it deals with Classic VB (VBA) ... The reason I posted here is because I can't get an answer (not even a hint) in the VB/VBA foums ... I searched the web extensively but without any luck

I hope you guys can ,at least, point me in the right direction

Problem:

I am trying to control the Undo/Redo Stack in excel but I can't seem to get a pointer to the UndoManager Interface in the ppv out argument when calling the QueryService Method .. it always returns Nothing ..

I hope someone can tell me what I am doing wrong .. I think the "SID_SApplicationObject" is not the right SID for what I am trying to achieve

Note : I am using the olelib.tlb

Code :
Sub Test()
    Dim pUnk As olelib.IUnknown
    Dim IServiceProvider As olelib.IServiceProvider
    Dim IID_IServiceProvider  As olelib.UUID
    Dim IID_IOleUndoManager As olelib.UUID
    Dim SID_SApplicationObject As olelib.UUID
    Dim ppv As IUnknown
    CLSIDFromString IIDSTR_IServiceProvider, IID_IServiceProvider
    CLSIDFromString "{0C539790-12E4-11CF-B661-00AA004CD6D8}", SID_SApplicationObject
    Set pUnk = Excel.Application
    pUnk.QueryInterface IID_IServiceProvider, IServiceProvider
    IServiceProvider.QueryService SID_SApplicationObject, IID_IOleUndoManager, ppv 
End Sub

Any help will be much appreciated
Regards.
