OwnerDraw CTabView

I want to display the tabs icon with different color font. I created my
class, but there were problems.class CCustomTabView : public
CTabView/*CWindowImpl<CCustomTabView,CTabView>*/,        public
COwnerDraw<CCustomTabView>{public: BEGIN_MSG_MAP(CCustomTabView) 
MESSAGE_HANDLER(WM_CREATE, OnCreate)  //CHAIN_MSG_MAP(CTabView) 
CHAIN_MSG_MAP_ALT(COwnerDraw<CCustomTabView>, 1) 
REFLECT_NOTIFICATIONS() END_MSG_MAP()
HBRUSH hBr; UINT bkColor;
LRESULT OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL&
bHandled) {  CreateTabControl();  return 0; }
bool CreateTabControl() {  m_tab.Create(m_hWnd, rcDefault, NULL,
WS_CHILD | WS_CLIPSIBLINGS | WS_CLIPCHILDREN | TCS_TOOLTIPS, 0,
m_nTabID);  ATLASSERT(m_tab.m_hWnd != NULL);  if(m_tab.m_hWnd == NULL)  
return false;
m_tab.SetFont(AtlGetDefaultGuiFont());
m_tab.SetItemExtra(sizeof(TABVIEWPAGE));
m_cyTabHeight = this->CalcTabHeight();
return true; }
void DrawItem(LPDRAWITEMSTRUCT pDS) {  LPDRAWITEMSTRUCT lpdis =
pDS/*(LPDRAWITEMSTRUCT) lParam*/; // item drawing information
if ( m_hWnd == lpdis->hwndItem)   // is this the tab control?  {   hBr =
CreateSolidBrush(RGB(255, 0, 0));   bkColor = RGB(0, 0, 255);
int cchBuff = 100;   LPTSTR szTabText = NULL;   ATLTRY(szTabText = new
TCHAR[cchBuff]);   if(szTabText == NULL)    return;
SecureHelper::strcpy_x(szTabText, cchBuff, _T(""));
TCITEMEXTRA tcix = { 0 };   tcix.tciheader.mask = TCIF_PARAM;  
tcix.tciheader.pszText = szTabText;   tcix.tciheader.cchTextMax =
sizeof(szTabText)-1;
if(m_tab.GetItem(lpdis->itemID, tcix) == FALSE)    return;
FillRect(lpdis->hDC, &lpdis->rcItem, hBr);   SetBkColor(lpdis->hDC,
bkColor);
TextOut(lpdis->hDC,    lpdis->rcItem.left,    lpdis->rcItem.top,   
tcix.tciheader.pszText,    lstrlen(tcix.tciheader.pszText));  } }};The
object not created. Calls: CCustomTabView::OnCreate ->
