替按钮添加背景颜色和字体颜色

为按钮添加背景颜色和字体颜色
/设置对话框的背景颜色及字体颜色
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
//为静态文本添加背景颜色和字体颜色
if(nCtlColor==CTLCOLOR_STATIC)
{
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkColor(RGB(255,255,255));//文字背景色
HBRUSH b=CreateSolidBrush(RGB(0,0,0));//控件背景色
return b;
}
//为编辑框添加背景颜色和字体颜色
else if(pWnd->GetDlgCtrlID()==IDC_LIST2)
{
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkColor(RGB(255,255,255));//文字背景色
HBRUSH b=CreateSolidBrush(RGB(0,0,0));//控件背景色
return b;
}
//为按钮添加背景颜色和字体颜色
else if(pWnd->GetDlgCtrlID()==IDC_BUTTON1)
{
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkColor(RGB(255,255,255));//文字背景色
HBRUSH b=CreateSolidBrush(RGB(0,0,0));//控件背景色
return b;
}

return hbr;

}

大神帮忙看看，怎么静态文本和编辑框都可以改变，按钮不行呢。必须要重写Cbutton类吗

------解决方案--------------------
必须重新CButton类，添加处理DrawItem虚函数，MSDN上有个例子代码

C/C++ code


// NOTE: CMyButton is a class derived from CButton. The CMyButton
// object was created as follows:
//
// CMyButton myButton;
// myButton.Create(_T("My button"), 
//      WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON|BS_OWNERDRAW, 
//      CRect(10,10,100,30), pParentWnd, 1);
//

// This example implements the DrawItem method for a CButton-derived 
// class that draws the button's text using the color red.
void CMyButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct) 
{
   UINT uStyle = DFCS_BUTTONPUSH;

   // This code only works with buttons.
   ASSERT(lpDrawItemStruct->CtlType == ODT_BUTTON);

   // If drawing selected, add the pushed style to DrawFrameControl.
   if (lpDrawItemStruct->itemState & ODS_SELECTED)
      uStyle |= DFCS_PUSHED;

   // Draw the button frame.
   ::DrawFrameControl(lpDrawItemStruct->hDC, &lpDrawItemStruct->rcItem, 
      DFC_BUTTON, uStyle);

   // Get the button's text.
   CString strText;
   GetWindowText(strText);

   // Draw the button text using the text color red.
   COLORREF crOldColor = ::SetTextColor(lpDrawItemStruct->hDC, RGB(255,0,0));
   ::DrawText(lpDrawItemStruct->hDC, strText, strText.GetLength(), 
      &lpDrawItemStruct->rcItem, DT_SINGLELINE|DT_VCENTER|DT_CENTER);
   ::SetTextColor(lpDrawItemStruct->hDC, crOldColor);
}

------解决方案--------------------

C/C++ code

class CButton : public CWnd
{
    DECLARE_DYNAMIC(CButton)

// Constructors
public:
    CButton();
    virtual BOOL Create(LPCTSTR lpszCaption, DWORD dwStyle,
                const RECT& rect, CWnd* pParentWnd, UINT nID);

// Attributes
    UINT GetState() const;
    void SetState(BOOL bHighlight);
    int GetCheck() const;
    void SetCheck(int nCheck);
    UINT GetButtonStyle() const;
    void SetButtonStyle(UINT nStyle, BOOL bRedraw = TRUE);

    HICON SetIcon(HICON hIcon);
    HICON GetIcon() const;
    HBITMAP SetBitmap(HBITMAP hBitmap);
    HBITMAP GetBitmap() const;
    HCURSOR SetCursor(HCURSOR hCursor);
    HCURSOR GetCursor();

#if (_WIN32_WINNT >= 0x501)
    BOOL GetIdealSize(SIZE* psize);
    BOOL SetImageList(PBUTTON_IMAGELIST pbuttonImagelist);
    BOOL GetImageList(PBUTTON_IMAGELIST pbuttonImagelist);
    BOOL SetTextMargin(RECT* pmargin);
    BOOL GetTextMargin(RECT* pmargin);
#endif  // (_WIN32_WINNT >= 0x501)

// Overridables (for owner draw only)
    virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);//[color=#FF0000]here[/color]

// Implementation
public:
    virtual ~CButton();
protected:
    virtual BOOL OnChildNotify(UINT, WPARAM, LPARAM, LRESULT*);
};
