Thanks,AliR. I modify my codes according to your suggestion. but there
still the same problem.What I want is like this: when I select the
first page,one dialog is shown up(not automatically) and when I select
the second page the other dialog is up. because I use DLL, it is not
easy to process the message TCN_SELCHANGE. i use the macro
TabCtrl_GetCurSel(), but I don't know why the return value is always
zero. Please help me!

The codes are like:
    //create tab control handler
    hwndTabCtrl=CreateWindow(WC_TABCONTROL,"",
        WS_CHILD|WS_CLIPSIBLINGS|WS_VISIBLE,0,0,rcClient.right,rcClient.bottom,hwndParent,NULL,g_hinst,NULL);
    if(hwndTabCtrl==NULL)
        AfxMessageBox("can't create tab control window");

    //create dialog for file

    pDialog[0]=new CPartDlg();
    pDialog[0]->Create(IDD_DIALOG_FOR_PART,NULL);

    //create dialog for machine
// CMachineDlg *pMachineDlg;
    pDialog[1]=new CMachineDlg();
    pDialog[1]->Create(IDD_DIALOG_FOR_MACHINE,NULL);

    //CREATE dialog for process
// CProcessDlg *pProcessDlg;
    pDialog[2]=new CProcessDlg();
    pDialog[2]->Create(IDD_DIALOG_FOR_PROCESS,NULL);

    //fill tab control's information
    m_tcitem.mask=TCIF_TEXT|TCIF_IMAGE;
    m_tcitem.iImage=-1;

    for(int i=0;i<TAB_PAGE_COUNT;i++)
    {
        m_tcitem.pszText=g_tabName[i];
        if(TabCtrl_InsertItem(hwndTabCtrl,i,&m_tcitem)==-1)
        {
         AfxMessageBox("can't insert");
         DestroyWindow(hwndTabCtrl);
        }
    }
             TabCtrl_AdjustRect(hwndTabCtrl,FALSE,&rcClient);

    TabCtrl_GetItemRect(hwndTabCtrl,0,&rcTab); //Get the tab page
dimension

    hdwp=BeginDeferWindowPos(1);
    DeferWindowPos(hdwp,hwndTabCtrl,NULL,rcClient.left,rcClient.top+100,(rcClient.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,0);
    EndDeferWindowPos(hdwp);
    int i_nPage=TabCtrl_GetCurSel(hwndTabCtrl);
    if(pDialog[i_nPage]->m_hWnd)
        pDialog[i_nPage]->ShowWindow(SW_HIDE);
    for(int j=0;j<3;j++)
    {
        pDialog[j]->SetWindowPos(&pDialog[j]->wndTop,
            rcClient.left,rcClient.top+100+rcTab.bottom-rcTab.top,
            (rcClient.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,SWP_HIDEWINDOW);
    }
    pDialog[i_nPage]->SetWindowPos(&pDialog[j]->wndTop,
            rcClient.left,rcClient.top+100+rcTab.bottom-rcTab.top,
            (rcClient.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,SWP_SHOWWINDOW);
    pDialog[i_nPage]->ShowWindow(SW_SHOW);

Thanks

In order for one dialog to be created as part of another window the Dialog
must have the WS_CHILD style, and by default CFileDialog has the WS_POPUP
style. There are ways around that, you can override the dialog template of
the file dialog and telling CFileDialog to load that instead.

The other thing is that you will have to use CFileDialog::Create method
instead of DoModal.

Hi,I am creating a tab control and want to pop up a file dialog when
clicking one tab page. but now, the file dialog was shown up at the
same time with tab control, not after selecting one page. Could some
guys help me? Thanks
