Answer 1

return CFormView::OnCtlColor(pDC, pWnd, nCtlColor);
这里替换成break试试

Answer 2

HBRUSH CFaceView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
    HBRUSH hbr = CFormView::OnCtlColor(pDC, pWnd, nCtlColor);
    
// 1. 测试直接返回 默认情况
// 2. 测试仅运行第一部分 if()
    if(pWnd-> GetDlgCtrlID()   ==  IDC_text)
    {
        pDC->SetBkMode(TRANSPARENT);
        pDC-> SetTextColor(RGB(250,0,0)); 
        pDC->SelectObject(&m_font);
        HBRUSH B = CreateSolidBrush(RGB(255,255,255));
        return (HBRUSH) B;
    }    
// 3. 测试仅运行第二部分 switch()
    switch(pWnd-> GetDlgCtrlID()) 
    {
             case IDC_RADIO1:
             case IDC_RADIO2:
             case IDC_RADIO3:
             case IDC_RADIO4:
             case IDC_RADIO5:
             case IDC_RADIO6:
             case IDC_RADIO7:
                 {
                     pDC->SetBkMode(TRANSPARENT);
                     pDC->SetTextColor(RGB(100,20,0));
                     pWnd->SetFont(&m_font);
                     HBRUSH B = CreateSolidBrush(RGB(200,100,50));
                     return (HBRUSH) B;
                 }
             default:
// 4. 测试执行两次CFormView::OnCtlColor() 没问题
                 return CFormView::OnCtlColor(pDC, pWnd, nCtlColor);
                 
         }        // TODO: Change any attributes of the DC here
    
    // TODO: Return a different brush if the default is not desired
    return hbr;
}
