'm_pWndEmptyCB' : undeclared identifier

While trying to convert an eVC++ project to VS2005, when I do a build I get the following error:

error C2065: 'm_pWndEmptyCB' : undeclared identifier      

The line of code is at the bottom of the followig

SHFullScreen( m_hWnd, SHFS_HIDESTARTICON|
                         SHFS_HIDETASKBAR|
                        SHFS_HIDESIPBUTTON );

MoveWindow(15,70,220,180,TRUE);

::CommandBar_Show(m_pWndEmptyCB->m_hWnd, FALSE );
