为了最大限度的发挥属性页的效用,首先让我们先从 CPropertySheet 继承一个新类,取名为 CMyPropSheet.
接着便可以进行下面的各种操作:

一、隐藏属性页默认按钮
隐藏掉Apply应用按钮:

propsheet.m_psh.dwFlags |= PSH_NOAPPLYNOW;
或隐藏掉Cancel取消按钮:CWnd *pWnd = GetDlgItem( IDCANCEL );
pWnd->ShowWindow( FALSE );

二、移动属性页按钮
首先,要获取按钮的句柄,然后就可以象对待窗体一样处理它们了. 下面代码先隐藏掉Apply和Help铵钮,再把OK和Cancel按移动到右侧。
BOOL CMyPropSheet::OnInitDialog ()
{
     BOOL bResult = CPropertySheet::OnInitDialog();

     int ids [] = {IDOK, IDCANCEL};//, ID_APPLY_NOW, IDHELP };

     // Hide Apply and Help buttons
     CWnd *pWnd = GetDlgItem (ID_APPLY_NOW);
     pWnd->ShowWindow (FALSE);
     pWnd = GetDlgItem (IDHELP);
     pWnd->ShowWindow (FALSE);

     CRect rectBtn;
     int nSpacing = 6; // space between two buttons...

     for( int i =0; i < sizeof(ids)/sizeof(int); i++)
      {
          GetDlgItem (ids [i])->GetWindowRect (rectBtn);

          ScreenToClient (&rectBtn);
          int btnWidth = rectBtn.Width();
          rectBtn.left = rectBtn.left + (btnWidth + nSpacing)* 2;
          rectBtn.right = rectBtn.right + (btnWidth + nSpacing)* 2;

          GetDlgItem (ids [i])->MoveWindow(rectBtn);
       }


    return bResult;
}


下面代码移动所有按钮到右侧,并且重新置属性页为合适的大小.
BOOL CMyPropSheet::OnInitDialog ()
{
     BOOL bResult = CPropertySheet::OnInitDialog();


     int ids[] = { IDOK, IDCANCEL, ID_APPLY_NOW };

     CRect rectWnd;
     CRect rectBtn;

     GetWindowRect (rectWnd);
     GetDlgItem (IDOK)->GetWindowRect (rectBtn);

     int btnWidth = rectBtn.Width();
     int btnHeight = rectBtn.Height();
     int btnOffset = rectWnd.bottom - rectBtn.bottom;
     int btnLeft = rectWnd.right - rectWnd.left;

     rectWnd.bottom = rectBtn.top;
     rectWnd.right = rectWnd.right + btnWidth + btnOffset;
     MoveWindow(rectWnd);

     rectBtn.left = btnLeft;
     rectBtn.right = btnLeft + btnWidth;

     for (int i = 0; i < sizeof (ids) / sizeof (int); i++)
      {
         rectBtn.top = (i + 1) * btnOffset + btnHeight * i;
         rectBtn.bottom = rectBtn.top + btnHeight;
         GetDlgItem (ids [i])->MoveWindow (rectBtn);
       }

    return bResult;
}


三、改变属性页上的标签文字

首先修改TC_ITEM结构,然后用 SetItem 来修改标签文字,如下代码:
TC_ITEM item;
item.mask = TCIF_TEXT;
item.pszText = "New Label";

//Change the label of the first tab (0 is the index of the first tab)...
GetTabControl ()->SetItem (0, &item);

四、改变属性页标签文字的字体属性

代码如下m_NewFont.CreateFont (14, 0, 0, 0, 800, TRUE, 0, 0, 1, 0, 0, 0, 0, _T("Arial") );
GetTabControl()->SetFont (&m_NewFont);

五、在属性页标签上显示位图
可以用 CImageList 建立图像. 用 SetItem 来设置,如下代码所示:
BOOL CMyPropSheet::OnInitDialog ()
{
     BOOL bResult = CPropertySheet::OnInitDialog();

     m_imageList.Create (IDB_MYIMAGES, 13, 1, RGB(255,255,255));
     CTabCtrl *pTabCtrl = GetTabControl ();
     pTabCtrl->SetImageList (&m_imageList);

     TC_ITEM item;
     item.mask = TCIF_IMAGE;
     for (int i = 0; i < NUMBER_OF_TABS; i++)
      {
         item.iImage = i;
         pTabCtrl->SetItem (i, &item );
      }

    return bResult;
}

六、在属性页左下角显示位图
如下代码所示:
void CMyPropSheet::OnPaint ()
{
     CPaintDC dc(this); // device context for painting

     int nOffset = 6;
     // load IDB_BITMAP1 from our resources
     CBitmap bmp;
     if (bmp.LoadBitmap (IDB_BITMAP1))
      {
         // Get the size of the bitmap
         BITMAP bmpInfo;
         bmp.GetBitmap (&bmpInfo);

         // Create an in-memory DC compatible with the
         // display DC we''re using to paint

         CDC dcMemory;
         dcMemory.CreateCompatibleDC (&dc);

         // Select the bitmap into the in-memory DC

         CBitmap* pOldBitmap = dcMemory.SelectObject (&bmp);

         // Find a bottom-left point for the bitmap in the client area
         CRect rect;
         GetClientRect (&rect);
         int nX = rect.left + nOffset;
         int nY = rect.top + (rect.Height () - bmpInfo.bmHeight) - nOffset;

         // Copy the bits from the in-memory DC into the on-
         // screen DC to actually do the painting. Use the centerpoint
         // we computed for the target offset.

         dc.BitBlt (nX, nY, bmpInfo.bmWidth, bmpInfo.bmHeight, &dcMemory, 0, 0, SRCCOPY);

         dcMemory.SelectObject (pOldBitmap);
        }

    // Do not call CPropertySheet::OnPaint() for painting messages
}


七、在属性页右下角显示3D文字Logo

代码如下:
void CMyPropSheet::OnPaint ()
{
    //在TAB按钮旁边显示3D文字提示,jingzhou xu
    Cstring m_LogoName = “属性页”;
    // if(m_LogoName == "")
    // return;

    GetWindowRect(rect);
    ScreenToClient(rect);

    LOGFONT logFont;
    ZeroMemory((void*)&logFont,sizeof(logFont));
    strcpy(logFont.lfFaceName,"宋体");
    logFont.lfHeight = -12;
    logFont.lfWeight = 400;
    logFont.lfCharSet = GB2312_CHARSET;
    logFont.lfOutPrecision = 3;
    logFont.lfClipPrecision = 2;
    logFont.lfQuality = 1;
    logFont.lfPitchAndFamily = 2;
    m_font.CreateFontIndirect(&logFont);
    SetFont(&m_font);
    CFont *pOldFont = pDC->SelectObject(&m_font);

    rect.left += 6;
    rect.right -= 6;
    rect.bottom -= 1;
    rect.top = rect.bottom - ITEMBUTTON_HEIGHT + 1;


    CFont m_LogoFont;
    CString sLogoString;

    m_LogoFont.CreateFont(rect.Height()*4/5, 0, 0, 0, FW_BOLD, 1, FALSE, FALSE,
    DEFAULT_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY,
    FIXED_PITCH | FF_ROMAN, "楷体_GB2312");

    sLogoString = m_LogoName;

    RECT m_rDataBox;
    CopyRect(&m_rDataBox,&rect);

    TEXTMETRIC tm;
    pDC->GetTextMetrics(&tm);
    CFont* oldFont = pDC->SelectObject(&m_LogoFont);
    CSize sz = pDC->GetTextExtent(sLogoString, sLogoString.GetLength());
    //用GetTextExtent来计算字体logo大小,依靠于设备环境,使用logo位于右下角
    m_rDataBox.left = m_rDataBox.right - sz.cx - tm.tmAveCharWidth/2;
    m_rDataBox.top = m_rDataBox.bottom - sz.cy - tm.tmHeight/5;
    pDC->SetBkMode(TRANSPARENT);
    //用3D字体显示,先黑后白,最后再用默认色
    COLORREF oldColor = pDC->SetTextColor(GetSysColor(COLOR_3DDKSHADOW));
    pDC->DrawText(sLogoString, sLogoString.GetLength(), &m_rDataBox, DT_VCENTER | DT_SINGLELINE |     DT_CENTER);
    m_rDataBox.left -= tm.tmAveCharWidth;
    pDC->SetTextColor(GetSysColor(COLOR_3DHILIGHT));
    pDC->DrawText(sLogoString, sLogoString.GetLength(), &m_rDataBox, DT_VCENTER | DT_SINGLELINE |     DT_CENTER);
    m_rDataBox.left += 3*tm.tmAveCharWidth/5;
    pDC->SetTextColor(RGB(0,0,255));
    pDC->DrawText(sLogoString, sLogoString.GetLength(), &m_rDataBox, DT_VCENTER | DT_SINGLELINE |     DT_CENTER);

    //释放资源

    pDC->SelectObject(oldFont);
    pDC->SetTextColor(oldColor);
    m_LogoFont.DeleteObject();
}

八、在属性页中动态加入其它控件
下面演示如何在左下角加入一Edit控件:
MyPropSheet.h中:
public:
CEdit m_edit;

MyPropSheet.cpp中:BOOL CMyPropSheet::OnInitDialog ()
  {
      BOOL bResult = CPropertySheet::OnInitDialog ();


      CRect rect;

      int nHeight = 24;
      int nWidth = 120;
      int nOffset = 6;

      GetClientRect (&rect);

      // Find a bottom-left point for the edit control in the client area
      int nX = rect.left + nOffset;
      int nY = rect.top + (rect.Height() - nHeight) - nOffset;

      // finally create the edit control
      m_Edit.CreateEx (WS_EX_CLIENTEDGE, _T("EDIT"), NULL,
      WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER,
      nX, nY, nWidth, nHeight, m_hWnd, 0, 0 );

      return bResult;
}
