如何将自定义属性添加到Shockwave Flash对象？

Question

Dim AllElementes As HtmlElementCollection = WebBrowser1.Document.All
For Each webpageelement As HtmlElement In AllElementes
    If webpageelement.GetAttribute("name") = "myvars" Then
        Dim login = webpageelement.GetAttribute("value")
        Label2.Text = login.ToString
    End If
Next 

我可以获取或绘制这些数据，但是我不知道如何在Flash Object中添加或导入它？
