Hi All,

I want to use the method of IRibbonUI object named "Invalidate" in my c++ code, but in C++ it is just a interface, not a class or other thing can define.

I saw a sample code in vb and which is what I want to get in c++, but I don't know how to do the same thing in c++, the sample code is as below:
Dim MyRibbon As IRibbonUI
Sub MyAddInInitialize(Ribbon As IRibbonUI)
    Set MyRibbon = Ribbon
End Sub
Sub myFunction()
    ‘ Invalidates the caches of all of this add-in’s controls 
End Sub

So the question is:"how to get the instance of IRibbonUI in C++, it is now just a IDISPATCH pointer I get in OnLoad() function".

hi - i had same and solved it :

signature idl file:

HRESULT OnLoad([in] IDispatch* pRibbon);

STDMETHODIMP CConnect::OnLoad(IDispatch* pRibbon)
        pRibbon->QueryInterface(__uuidof(Office::IRibbonUI), (void**)&m_pRibbonUI);
        return S_OK;
CComPtr<office::iribbonui xmlns:office="#unknown">		m_pRibbonUI;</office::iribbonui>

and than just call where you need


and dont forget invalidate refresh all of your custom controls to re-initialize, better if you use
InvalidateControl(string controlID)
