I want VB to verify that the typed username already exists in a text file hosted on a site. I want something like this:

Dim Findstring = IO.File.ReadAllText("C:\Program Files (x86)\EasyPHP-12.1\www\server\users.txt")
Dim Lookfor As String = FlatTextBox1.Text

if Findstring.Contains(Lookfor) Then
   ErroUserExist.ShowDialog()

But instead of looking for txt on my pc, I want it to search on a website. Thank you in advance.
