title: How to send data to a particular Client from server?
body: <p>I have programmed a chat application in VB but as soon as I send any data from a client the server will send it to all.  It should send a reply only to a particular client.
  This is the function I have used.</p>
  
  <pre><code>Dim objClient As Client
  Dim d As DictionaryEntry
  For Each d In mcolClients
      objClient = d.Value
      objClient.Send(Data &amp; vbLf)
  Next
  </code></pre>
  
  <p>Where <code>mcolClients</code> is a hash table.</p>
