tcp client and sslstream in .net

[nevviin]

Hi,


I have developed a VB.NET windows application to read mails from the server.

I am using tcpclient object to read mail from mail server. I am uisng the IMAP and POP protocols for reading the mails. For this i used to send command using write command of ssl stream and read the response using the reader



Dim sslstream As Net.Security.Ss lStream
Dim reader As StreamReader = Nothing
Dim objTCP As New TcpClient


objTCP.Connect( POPserver, Port)
sslstream = New Net.Security.Ss lStream(objTCP. GetStream())
reader = New StreamReader(ss lstream)

writing data(commands)
Data = strCmd & vbCrLf
SzData = System.Text.Enc oding.ASCII.Get Bytes(Data.ToCh arArray())
sslstream.Write (SzData, 0, SzData.Length)



reading the response


tmpString = reader.ReadLine ()
If tmpString.Subst ring(0, 4) <> "-ERR" Then
While (tmpString <> "." )
tmpString = reader.ReadLine
End While
End If

The application has to run 24/7 and 365 days with out any stopping.
Problem i am facing i am getting the exceptions while writing and reading
some times application hangs also

Applications is almost done and in the final stage I am stuck with this issue.

I am pasting the exception i am getting while writing and reading

writing exception
Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sock ets.SocketExcep tion: An existing connection was forcibly closed by the remote host
at System.Net.Sock ets.Socket.Send (Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
at System.Net.Sock ets.NetworkStre am.Write(Byte[] buffer, Int32 offset, Int32 size)


reading exception
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

can anybody please suggest me a solution to fix this

thanks & regards

If you use .NET, I highly recommend this IMAP component. I found it after I had spent the whole day to try almost available components on the internet. It's better than the others. Other mail components can be found here: POP3 Component, SMTP Component. If you need mail merge (my project needs it), check out this Mail Merge component.
