Hi,

I have used WebBrowser in the windows forms and have added it and i want to get the count of all the images, video links and flash in the web page.
i am able to get the count of images and video links. but cant capture if there is a flash present or not.

推荐答案

Dim elements As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("object")
For Each element As HtmlElement In elements
    ' "CLSID:D27CDB6E-AE6D-11cf-96B8-444553540000" is clsid for SWFObject
    ' clsid was confirmed here: http://helpx.adobe.com/flash/kb/object-tag-syntax-flash-professional.html
    Dim attr As String = element.GetAttribute("classid")
    If "clsid:d27cdb6e-ae6d-11cf-96b8-444553540000".Equals(attr, StringComparison.OrdinalIgnoreCase) Then
MessageBox.Show("SWF Object found")
    End If
Next
' Now search for embed tag
elements = WebBrowser1.Document.GetElementsByTagName("embed")
For Each element As HtmlElement In elements
    If element.OuterHtml.IndexOf("application/x-shockwave-flash", StringComparison.OrdinalIgnoreCase) >= 0 Then
MessageBox.Show("Embedded SWF found")
    End If
Next

希望这有帮助。
