动态创建ActiveX控件

竟然可以先在Dialog中画一个Group Box用于定位，程序运行起来后把它的位置信息放到rect中，就把它销毁了！
再后来，动态地创建了一个IE控件，位置呢就用rect。代码：











LRESULT CAboutDlg::OnInitDialog(...)
{
CWindow wndPlaceholder = GetDlgItem ( IDC_IE_PLACEHOLDER );
CRect rc;
CAxWindow wndIE;
 
    // Get the rect of the placeholder group box, then destroy 
    // that window because we don't need it anymore.
    wndPlaceholder.GetWindowRect ( rc );
    ScreenToClient ( rc );
    wndPlaceholder.DestroyWindow();
 
    // Create the AX host window.
    wndIE.Create ( *this, rc, _T(""), 
                   WS_CHILD | WS_VISIBLE | WS_CLIPCHILDREN );
