[ulasoc]

i need to get source of facebook video page. Unfortunately i can't reach whole contents related video links.

page link

"http://www.facebook.com/photo.php?v=360736417354431"

for example i cant get this
" ["video_src","http\u00253A\u00252F\u00252Fvideo.ak.fbcdn.net\u00252Fcfs-ak-snc6\u00252Fv\u00252F232405\u00252F104\u00252F360736417354431_28435.mp4 "

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim sourceString As String = New

System.Net.WebClient().DownloadString("http://www.facebook.com/photo.php?v=360736417354431")
        RichTextBox1.Text = sourceString

End Sub

its possible to view all in Chrome or ie but
i cant also see video content in WebBrowser object.
