SUMMARY
=======

To change the color of text on the selected tab of a property sheet, you need to
subclass the tab control associated with the property sheet and make it owner
drawn.

Override the DrawItem method of your class derived from CTabCtrl and change the
color of text before displaying it.

MORE INFORMATION
================

1. Create a new class called CMyTabCtrl deriving from CTabCtrl. Override the
  DrawItem method for CTabCtrl. Because ClassWizard does not show this method,
  this method needs to be added manually. The sample code below shows how to
  change the color of the text of the selected tab:

  void CMyTabCtrl::DrawItem(LPDRAWITEMSTRUCT lpDIS)
  {
       TC_ITEM tci;
       CDC* pDC = CDC::FromHandle(lpDIS->hDC);
       CRect rect(lpDIS->rcItem);
       char szTabText[256];
       memset(szTabText,'\0',sizeof(szTabText));
       
       tci.mask = TCIF_TEXT;
       tci.pszText = szTabText;
       tci.cchTextMax = sizeof(szTabText) -1;
       GetItem(lpDIS->itemID, &tci);
       
       if (lpDIS->itemAction & ODA_DRAWENTIRE)
       {
           pDC->TextOut(rect.left+5, rect.top+5, tci.pszText);
       }
       
       if ((lpDIS->itemState & ODS_SELECTED) && 
           (lpDIS->itemAction & (ODA_SELECT | ODA_DRAWENTIRE)))
       {
           //Make the color of text of the selected tab to be BLUE.
           pDC->SetTextColor(RGB(0,0,255));
           pDC->TextOut(rect.left+5, rect.top+5, tci.pszText);
       }
  }

2. Create a new class, CMyPropertySheet, derived from CPropertySheet and add a
  member variable m_myTabCtrl of type CMyTabCtrl.

  Add a handler for WM_INITDIALOG message. After the call to the base class
  OnInitDialog, add the code as shown below to subclass the tab control and
  make it an owner-drawn control:

  BOOL CMyPropertySheet::OnInitDialog()
  {
     BOOL bResult = CPropertySheet::OnInitDialog();

     /* Subclass the tab control. */ 
     m_myTabCtrl.SubclassWindow(GetTabControl()->m_hWnd);

     /* Make it owner drawn. */ 
     m_myTabCtrl.ModifyStyle(0,TCS_OWNERDRAWFIXED);

     return bResult;
  }

Now, use CMyPropertySheet instead of CPropertySheet in your application.
