I just wanted to post a update. We have discovered the root of our problem.
OurApp::InitInstance::_AtlBaseModule seems to be different from
CWinApp::InitInstance::_AtlBaseModule.

So when we call into CWinApp::InitInstance from our OurApp::InitInstance
the _AtlBaseModule.SetResourceInstance(m_hLangResourceDLL) is not setting the
resource instance on the _AtlBaseModule that our application is actually
using. I'm not sure why this would be. We are running our test on Windows7
x64 using WOW so that could be a factor.

A simple workaround is to call AfxGetResourceHandle() and then
_AtlBaseModule.SetResourceInstance() after then CWinApp::InitInstance all
returns.

So when we call into the base class

We have been diving into this problem and it looks like ATL should be picking
up the same resource only dll that MFC is using.

Here in InitInstance() it is correctly picking up our resource only dll and
calling SetResourceInstance and SetResourceHandle.

BOOL CWinApp::InitInstance()
{
    InitLibId();
    m_hLangResourceDLL = LoadAppLangResourceDLL();
    if(m_hLangResourceDLL != NULL)
    {
        AfxSetResourceHandle(m_hLangResourceDLL);
        _AtlBaseModule.SetResourceInstance(m_hLangResourceDLL);
    }

    return TRUE;
}

The problem is that after InitInstance returns the
_AtlBaseModule.GetResourceInstance is returning a different handle then
AfxGetResourceHanlde. Somehow the _AtlBaseModule.m_hInstResource is being
changed and I have not been able to figure out what is causing it. Setting a
data breakpoint on m_hInstResource did not catch it.
