1.创建一个MFC对话框，改变static背景色，字体颜色

BOOL CteststaticcolorDlg::OnInitDialog()
{
    CDialogEx::OnInitDialog();
 
    // 将“关于...”菜单项添加到系统菜单中。
 
    // IDM_ABOUTBOX 必须在系统命令范围内。
    ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
    ASSERT(IDM_ABOUTBOX < 0xF000);
 
    CMenu* pSysMenu = GetSystemMenu(FALSE);
    if (pSysMenu != nullptr)
    {
        BOOL bNameValid;
        CString strAboutMenu;
        bNameValid = strAboutMenu.LoadString(IDS_ABOUTBOX);
        ASSERT(bNameValid);
        if (!strAboutMenu.IsEmpty())
        {
            pSysMenu->AppendMenu(MF_SEPARATOR);
            pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
        }
    }
 
    // 设置此对话框的图标。  当应用程序主窗口不是对话框时，框架将自动
    //  执行此操作
    SetIcon(m_hIcon, TRUE);         // 设置大图标
    SetIcon(m_hIcon, FALSE);        // 设置小图标
 
    // TODO: 在此添加额外的初始化代码
    m_font1.CreatePointFont(120, TEXT("Impact"));
    m_font2.CreatePointFont(120, TEXT("Arial"));
 
    return TRUE;  // 除非将焦点设置到控件，否则返回 TRUE
}

HBRUSH CteststaticcolorDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    HBRUSH hbr = CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);
 
    // TODO:  在此更改 DC 的任何特性
    if (nCtlColor == CTLCOLOR_STATIC)
    {
        switch (pWnd->GetDlgCtrlID())
        {
        case IDC_STATIC1:
            pDC->SetTextColor(RGB(255, 0, 0));
            pDC->SetBkColor(RGB(255, 255, 255));
        //  pDC->SetBkMode(TRANSPARENT);
            pDC->SelectObject(&m_font1);
            return (HBRUSH)::GetStockObject(BLACK_BRUSH);
            break;
        case IDC_STATIC2:
            pDC->SetTextColor(RGB(255, 255, 0));
            pDC->SetBkColor(RGB(255, 255, 255));
            pDC->SelectObject(&m_font2);
            pDC->SetBkMode(TRANSPARENT);
            return (HBRUSH)::GetStockObject(BLACK_BRUSH);
            break;
        default:
            break;
        }
    }
 
    // TODO:  如果默认的不是所需画笔，则返回另一个画笔
    return hbr;
}
