How to detect the socket's status of the remote side?

i am writting my own winsock component use the system.net namespace. i have done the connection, getdata and send data section. but when i try to write a property that allow user to retrieve the status of the connection... i stucked! i have a difficulty to acquire the status of the remote socket.. that means how i going to know the remote socket that connect to my socket is drop out or etc.. can someone give me any idea on how to do this. thanks

you really just have to roll your own state property code. It is just a matter of setting it in your class to whatever value is appropriate when appropriate.

From some code I got, if the server receives data at 0 length then it is disconnected. It looked like this

Code:

---

Private Sub DoStreamReceive(ByVal ar As IAsyncResult)
    Dim intCount As Integer

    Try
      SyncLock mobjClient.GetStream
        intCount = mobjClient.GetStream.EndRead(ar)
      End SyncLock
      If intCount < 1 Then
        ' Socket has disconnected
        Exit Sub
      End If

I hope that helps you out
