    Question telnet server, how to program a backspace

    I have a small, probably poorly coded telnet server. You connect, it shows some ansci art and then you just type to chat and it displays your ip address following your message. The problem I'm having is implementing a backspace. When you use backspace in command prompt it simply just moves the cursor back without deleting the character.

    I'm using network stream streamreader and streamwriter for the streams. Is there something better than that I should be aware of?

    I've pulled some code from a visual basic 6 telnet application and its for a backspace key. My vb is poor now having swapped over to c#.net a long time ago so I don't understand it. Maybe someone just translating it might help me:
    Code:
    DataVal = Asc(DataChar)
    DataValSet = ""
    For t% = 1 To Len(DataChar)
        DataValSet = DataValSet + Str$(Asc(Mid$(DataChar, t%, 1)))
    Next t%
    If (DataVal = 8 Or DataVal = 127) Then
        If Len(LineBuffer(ConnID)) > 0 Then
            'echo it back
            If UserData(ConnID, 7) <> "1" Then SocketPlayerEcho ConnID, DataChar
            LineBuffer(ConnID) = Left$(LineBuffer(ConnID), Len(LineBuffer(ConnID)) - 1)
           If UserData(ConnID, 7) <> "1" Then SocketPlayerEcho ConnID, " "
          If UserData(ConnID, 7) <> "1" Then SocketPlayerEcho ConnID, DataChar
        End If
    I no the Dataval = 8 is refering to the backspace key but thats it. Can someone please help me ouT!

    That's Visual Basic, not C#.

    I think what I want to do is create connection where the buffer is read before its even sent to the server. Are there any other ways instead of networkstream and streamreader?

    Perhaps you should pull your head out of your ass, stop being suck a ........ing jackass and look at the name of the forum in which you posted this, as well as the general name of the URL.

    He is looking for a C# solution. Where else should he post but in a C# forum?

    Watch your language. Consider this a formal warning.

    When in doubt, read the FAQ.
    Then ask a smart question.
