Martin,

below you will find the code I am using to localize my application.
Just replace my defined types by standard MFC (boolean_t = BOOL)

void CMainApp::LoadUIResources()
{
    vlwGetLangResName( _T("Foo.dll"), m_hResourceInstance);
    ASSERT( m_hResourceInstance );
}

Once an resource instance has been loaded
you can do CString sTmp.LoadString(hResourceInstance , IDS_YOUR_ID);
So I know it works for String resources.

About Other type of resources icon, bmp, you can use win32 calls:

HBITMAP hBmp = ::LoadBitmap(hResourceInstance , IDB_FOO);
