Ribbon: custom control sample?

Create a CDialog class and then do the following:

 

CMyDlg m_MyDlg;

 

CXTPControlPopup *pControlPopup = (CXTPControlPopup *)pRibbonGroup->Add( xtpControlPopup, ID_MY_BUTTON );
pControlPopup->SetBeginGroup( TRUE );

m_AddCustomDlg.Create( MAKEINTRESOURCE( CMyDlg::IDD ), m_pWnd );
 CXTPControlCustom *pControlCustom = CXTPControlCustom::CreateControlCustom( &m_MyDlg );
 (CXTPControlCustom *)pControlPopup->GetCommandBar()->GetControls()->Add( pControlCustom );

Any problems please let me know
