ATL中修改文本控件的文本颜色

1、添加以下宏，处理WM_CTLCOLOR*消息

 

MESSAGE_HANDLER(WM_CTLCOLOR*, OnCtlColor)

 

2、在OnCtlColor中：

LRESULT CAboutDlg::OnCtlColor(UINT /*uMsg*/, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
       CWindow  wndText1 = GetDlgItem(IDC_TEXT1);

       HDC  hdc = (HDC)wParam;

       if ( (HWND)lParam == wndText1 .m_hWnd )
       {

            ::SetTextColor(hdc, RGB(255, 0, 0));
            ::SetBkColor(hdc, ::GetSysColor(CTLCOLOR_DLG));

 

            // 返回一个画刷告知该消息已处理，不用执行默认动作了
            return (LRESULT)::GetSysColorBrush(CTLCOLOR_DLG);       

        }

        return 0;
}
