sending over asynchronous socket connect and disconnect

[trymore]

Hi all,

can anybody help me out there? I am developing a client sockect to send transactions form a DB to a server socket. the way i want is to connect, send, recieve , disconnect, connect, send, recieve and disconnect.... like that until all the transactions are uploaded. my problem is when i send, I am shutting down the socket and when i try to connect and send again i get the following error "Once the socket has been disconnected, you can only reconnect again asynchronously, and only to a different EndPoint. BeginConnect must be called on a thread that won't exit until the operation has been completed."

what do you mean creating a socket fopr each connection? do you mean a different endpoint or just a different socket name but connecting to the same EP(IP addr and port)?
i can see we are getting closer bro.

this is the code i am using. have a look at it. It is in a while loop and r is the looping variable i am using.

Try
If client1.Connect ed = False Then
client1.BeginCo nnect(remoteEP, New AsyncCallback(A ddressOf Async.ConnectCa llback1), client1)
End If
'System.Threadi ng.Thread.Sleep (3000) ' pause for three secs to allow recieving of ENQ

' Wait for connection.
Async.connectDo ne.WaitOne()
'If ReceiveENQ(clie nt) = "05" Then

' Send data to the remote device.
System.Threadin g.Thread.Sleep( 5000) ' pause for three secs to allow recieving of ENQ
Async.Send1(cli ent1, buffer1)
Async.sendDone. WaitOne()
Async.Receive1( client1) ' recieve ack
Async.Receive1( client1) ' recieve resp
System.Threadin g.Thread.Sleep( 3000)
' Receive the response from the remote device.
Async.Send1(cli ent1, Chr(6)) ' send ack
Async.sendDone. WaitOne()
Async.Send1(cli ent1, bufferZone1) ' send CONF REQUEST
Async.sendDone. WaitOne()

Async.Receive1( client1) ' recieve ack
System.Threadin g.Thread.Sleep( 2000)
'receiveDone.Wa itOne()
Async.Send1(cli ent1, Sringer1)
Async.sendDone. WaitOne()
'System.Threadi ng.Thread.Sleep (5000)
' client1.Close()
'System.Threadi ng.Thread.Sleep (2000)
' Write the response to the console.
client1.Disconn ect(True)
Catch e As Exception
Console.WriteLi ne(e.Message)
Console.WriteLi ne("error in the sending region of code ")

Finally
r += 1

End Try

its solved now. cheers,

Hi,

I am getting the same error message with below code. What should I modify to get it working?

Private Sub clnt_reboot()
For n = ipcounterstart To ipcounterend
Dim mySocket = New Socket(AddressF amily.InterNetw ork, SocketType.Stre am, ProtocolType.Tc p)

Try
Do While (i < Reboot.Length)
j = Reboot.IndexOfA ny(reserved, i)
If (j = -1) Then
UrlEncoded.Appe nd(HttpUtility. UrlEncode(Reboo t.Substring(i, (Reboot.Length - i))))
Exit Do
End If
UrlEncoded.Appe nd(HttpUtility. UrlEncode(Reboo t.Substring(i, (j - i))))
UrlEncoded.Appe nd(Reboot.Subst ring(j, 1))
i = (j + 1)
Loop
SomeBytes = Encoding.UTF8.G etBytes(UrlEnco ded.ToString)
Dim ep As New IPEndPoint(IPAd dress.Parse(net & "." & ipcounterstart) , Convert.ToInt16 (startport))
socket.Connect( ep)
socket.SendTo(S omeBytes, ep)
Dim cnt As Integer = 0
Dim bytBuffer As Byte() = New Byte(&H400 - 1) {}
Do
cnt = socket.Receive( bytBuffer)
socket.SetSocke tOption(SocketO ptionLevel.Sock et, SocketOptionNam e.ReceiveTimeou t, 30)
Loop While (cnt <> 0)
Catch ex As Exception
MessageBox.Show (ex.Message)
End Try
mySocket.close( )

Next
MessageBox.Show ("Reboot has been send")
ipcounterstart = startoktett
End Sub
