RE: Change Property Sheet Size?

Hi, all:

My MFC application is Dialog based and I need to adjust the dialog
size based on user's screen resolution. (which works fine). I have a
property sheet with 2 property pages on my dialog. I tried to adjust
the property sheet size when the dialog size adjusted, basically just
expand the property sheet to occupy the whole dialog, but I could not
have it done. Following is my code:

/*
CMyPage1, CMyPage2 are classes derived from CPropertyPage
*/

CPropertySheet* m_pMainTabs;
CPropertyPage* m_pMyPage1;
CPropertyPage* m_pMyPage2;

  BOOL CMyDlg::OnInitDialog()
{
    CDialog::OnInitDialog();
    //resize window to maximum screen size
    CSize screenSize;
    screenSize.cx = ::GetSystemMetrics(SM_CXSCREEN);
    screenSize.cy = ::GetSystemMetrics(SM_CYSCREEN);
    MoveWindow(0,0, screenSize.cx, screenSize.cy);

        //create property sheet and pages
        m_pMyPage1 = new CMyPage1();
    m_pMyPage2 = new CMyPage2();

    m_pMainTabs = new CPropertySheet;

    //Resize PropertySheet before add pages
    CRect rcDlg, rcSheet;
    GetWindowRect(&rcDlg);
    ScreenToClient( &rcDlg );

    m_pMainTabs->SetWindowPos( NULL, rcDlg.left, rcDlg.top, rcDlg.Width()
+100, rcDlg.Height()+100,
            SWP_NOZORDER | SWP_NOACTIVATE );

    m_pMainTabs->AddPage(m_pMyPage1);
    m_pMainTabs->AddPage(m_pMyPage2);

    m_pMainTabs->Create(this, WS_CHILD | WS_VISIBLE);
    m_pMainTabs->ModifyStyleEx (0, WS_EX_CONTROLPARENT);
    m_pMainTabs->ModifyStyle( 0, WS_TABSTOP );

        m_pMainTabs->SetActivePage(m_pMyPage1);
}

thanks in advance
