Imports System.Net 
Public Class Form1 
    Private url As String 

    Private Function CheckSite(ByVal url As String) As String 
     Dim Block As Boolean = False 
     Dim blocklist As String = "blocksys.com,abc.com,domain.com,another.com" 
     Dim myList As String() = blocklist.Split(New Char() {","c}) 
     For Each checkBlock As String In myList 
      If url.IndexOf(checkBlock) <> -1 Then Block = True 
     Next 
     Return Block 
    End Function 

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
     url = TextBox1.Text 
     If CheckSite(url) = True Then 
      MessageBox.Show("This application has been blocked by administrator", "Application blocked", MessageBoxButtons.OK, MessageBoxIcon.Error) 
      Exit Sub 
     Else 
      Dim ws As New WebClient 
      ws.DownloadString(url) 
      'Another process........ 
     End If 
    End Sub 
End Class
