I wrote a SDI application where I switch bewteen views.
The problem is now it seems I don't receive windows message after having
switched from mainview to another view.For instance I cannot enter text
in edit box.

Here is the code used to switch :

LRESULT CMainFrame::OnSwitchView( WPARAM wParam, LPARAM lParam )
    CViewMgr* pViewMgr = CViewMgr::GetInstance();
    CViewMgr::ViewInfo viewInfo = pViewMgr->GetViewInfo( (CViewMgr::ViewID)
wParam );

    CRuntimeClass* pNewViewClass = viewInfo.pViewClassName;

    CView* pOldActiveView = STATIC_DOWNCAST( CView, GetActiveView() );

    // If we're already displaying this kind of view, no need to go further.
    if ( pOldActiveView->IsKindOf(pNewViewClass) ) {
        return 0L;

    // Set the child window ID of the active view to AFX_IDW_PANE_FIRST.
    // This is necessary so that CFrameWnd::RecalcLayout will allocate
    // this "first pane" to that portion of the frame window's client
    // area not allocated to control bars. Set the child ID of
    // the previously active view to some other ID.
    ::SetWindowLong( pOldActiveView->m_hWnd, GWL_ID, 0 );

    // create the new view
    CCreateContext context;
    context.m_pNewViewClass = pNewViewClass;
    context.m_pCurrentDoc = GetActiveDocument();
    //pCurrentDoc->m_bAutoDelete = FALSE;
    CView* pNewView = STATIC_DOWNCAST(CView, CreateView( &context ));
    if ( pNewView != NULL ) {
        // set the commandBar
        CreateCommandBar( viewInfo.nCmdBarId );
        // the new view is there, but invisible and not active...
        pNewView->ShowWindow( SW_SHOW );


        // redim
        SetActiveView( pNewView );

#ifdef _DEBUG
    else {
        ASSERT(FALSE); // big problem !!!!

    return 0L;
Any idea ?
