How to change text color in a hotkey using MFC?

Question

The question is like this: define a new class inheritance CHotKeyCtrl, I want to change the text color in hotkey. Using ON_WM_CTLCOLOR_REFLECT,but the test color is not changed.the onctlcolor function cannot run.

MyHotKey.h
class CMyHotKey: public CHotKeyCtrl
{
   DECLARE_DYNAMIC(CMyHotKey)
   protected:
   DECLARE_MESSAGE_MAP()
   public: 
   afx_msg HBRUSH CtlColor(CDC* pDC, UINT nCtlColor);
};
MyHotKey.cpp    
BEGIN_MESSAGE_MAP(CMyHotkey, CHotKeyCtrl) 
   ON_WM_CTLCOLOR_REFLECT()
   ON_WM_ERASEBKGND()
END_MESSAGE_MAP()
HBRUSH CMyHotKey::CtlColor(CDC* pDC, UINT nCtlColor)
{
   if(pDC)
   {
       pDC->SetTextColor(RGB(255,0,0));
       pDC->SetBkMode(TRANSPARENT);
   }
   return (HBRUSH)GetStockObject(NULL_BRUSH);
}

Can anyone suggest what I might be doing wrong?
