Greetings.
I recently inherited an addin designed for VS2003.
I was asked to get it running and update it in VS2005.
It is written in native C++.

I made sure to update the .rgs file so that it points to 8.0 instead of 7.1
. The addin compiles and displays in the Addin Manager. When enabled, it adds
in item to the Tools menu. Next, it is supposed to add a submenu to that.
This is where it fails.
I have tracked down the exact point at which it fails. Below is the relavent
code.

// Private field
POfcCommandBarControl m_pControlXMPopup;

// Inside a method to setup menu
POfcCommandBar pToolsBar;
POfcCommandBarControls pControls;
POfcCommandBars pBars;

// Get command bar interface
m_pDTE->get_CommandBars( (EnvDTE::_CommandBars**) &pBars);
// Acquire Tools menubar
pBars->get_Item( CComVariant( "Tools" ), &pToolsBar);
// Get controls
pToolsBar->get_Controls( &pControls);

// Create popup menu
pControls->Add( CComVariant( Office::msoControlPopup ), CComVariant(1),
CComVariant(), CComVariant(1), varFalse, &m_pControlXMPopup);

// !!! This fails in VS2005 !!!
// returns NULL
// QueryInterface returns E_NOINTERFACE
POfcQICCommandBarPopup pPopup = m_pControlXMPopup;

m_pControlXMPopup is non-null. The typedef resolves to
ATL::CComPtrBase<Office::CommandBarControl>. The assignment results in an
automatic call to CComQIPtr(__in_opt IUnknown* lp) {...} in atlcomcli.h. This
method calls QueryInterface and results in E_NOINTERFACE.

I need the POfcQICCommandBarPopup to call get_CommandBar() and then add new
items to it.

The code worked fine in VS2003, which is a little puzzling.
What is wrong here?
Are there any alternatives or workarounds?

Regards.
