Well in my DataArrival on my bot it seems to be having a problem splitting the packets that are sent combined or when i reach &HF chat packet and was seeing if anyone could see where it may be going out of bounds?
Dunno if this is the right forum or not but I thought it would be the best since it's dealing with Battle.net Packets


Heres the Code:

[code]
    Private Sub wSock_onDataArrival(ByVal sData() As Byte, ByVal iTotalBytes As Integer, ByVal sNow As String) Handles wSock.onDataArrival
        Dim tempBuff(iTotalBytes - 1) As Byte, pLen As Integer
        Array.Copy(sData, 0, tempBuff, 0, iTotalBytes)
        pLen = tempBuff(2)
        While pLen > 4
            Dim p1(pLen - 1) As Byte
            Array.Copy(tempBuff, 0, p1, 0, pLen)
            Parsep(wSock, p1)
            Array.Copy(tempBuff, pLen, tempBuff, 0, tempBuff.Length)
            pLen = tempBuff(2)
        End While
    End Sub
[/code]

Anyone see the error? Thanks in advance!

[code]
'check the temp buffer and see if you have more then 2 bytes..
if TempBuff.Length > 2 then
'get your packet length and test the rest
if pLen > TempBuff.Length then
'your packet is not all in the buffer yet wait for the rest of it
else
'you have the packet, process it.
end if
else
'your packet is incomplete wait for the rest of it.
end if
[/code]
Sloppy quick write up, might give you an idea of the posable problem.

Let me see if im getting what your saying. Check if the tempBuff length is greather then 2 before i parse.

Like this?

[code]
    Private Sub wSock_onDataArrival(ByVal sData() As Byte, ByVal iTotalBytes As Integer, ByVal sNow As String) Handles wSock.onDataArrival
        Dim tempBuff(iTotalBytes - 1) As Byte, pLen As Integer, used As Integer
        Array.Copy(sData, 0, tempBuff, 0, iTotalBytes)
        pLen = tempBuff(2)
        While pLen > 4
            If tempBuff.Length > 2 Then
                Dim p1(pLen - 1) As Byte
                Array.Copy(tempBuff, 0, p1, 0, pLen)
                Parsep(wSock, p1)
                Array.Copy(tempBuff, pLen, tempBuff, 0, tempBuff.Length)
                pLen = tempBuff(2)
            End If
        End While
    End Sub
[/code]

Still going out of bounds.

no no lol check the temp buffer befor you try getting the pLen.

Same thing.

[code]
    Private Sub wSock_onDataArrival(ByVal sData() As Byte, ByVal iTotalBytes As Integer, ByVal sNow As String) Handles wSock.onDataArrival
        Dim tempBuff(iTotalBytes - 1) As Byte, pLen As Integer, used As Integer
        Array.Copy(sData, 0, tempBuff, 0, iTotalBytes)
        If tempBuff.Length > 2 Then
            pLen = tempBuff(2)
            While pLen > 4
                If tempBuff.Length > 2 Then
                    Dim p1(pLen - 1) As Byte
                    Array.Copy(tempBuff, 0, p1, 0, pLen)
                    Parsep(wSock, p1)
                    Array.Copy(tempBuff, pLen, tempBuff, 0, tempBuff.Length)
                    pLen = tempBuff(2)
                End If
            End While
        End If
    End Sub
[/code]

Any more ideas?

Same thing.

I would suggest maybe building an incoming buffer class so you could do your while loop like.
[code]
while class.dowehaveafullpacket()
Parse(class.GetPacket())
end while
[/code]
Only thing I can think of right now is that your forgetting to store your temp buffer and add the previous data to it.

hrmm... but is a incoming buffer class really needed? if i can get this while loop working it would be much less code and just as efficient =\

Edit:

I have re-written my dataarrival and I still seem to be getting an error...

[code]
    Private Sub wSock_onDataArrival(ByVal sData() As Byte, ByVal iTotalBytes As Integer, ByVal sNow As String) Handles wSock.onDataArrival
        Dim tempBuff(iTotalBytes - 1) As Byte, pLen As Integer, used As Integer
        used = 0
        Array.Copy(sData, 0, tempBuff, 0, iTotalBytes)
        pLen = tempBuff(2)

        While used <> iTotalBytes
            Dim p1(pLen - 1) As Byte
            Array.Copy(tempBuff, used, p1, 0, pLen)
            Parsep(wSock, p1)
            used = used + pLen
            If used <> iTotalBytes Then
                pLen = used + 2
            End If
        End While
    End Sub
[/code]

I use the Step-Into Debugger to follow it, it exits the loop when used = itotalbytes and getings to 'End Sub' then errors...

Heres my DataArrival for my System.net.Socket:

[code]
    Private Sub sockDataArrival(ByVal ar As IAsyncResult)
        Dim bytesRead As Integer

        Try
            bytesRead = tcpClient.EndReceive(ar)
        Catch
            Exit Sub
        End Try

        Try
            Dim Data() As Byte = sBuffer
            If bytesRead = 0 Then
                tcpClient.Shutdown(SocketShutdown.Both)
                tcpClient.Close()
                RaiseEvent onDisconnect(dDate.Now)
                Exit Sub
            End If
            ReDim sBuffer(256)

            tcpClient.BeginReceive(sBuffer, 0, iBuffer, 0, AddressOf sockDataArrival, tcpClient)
            RaiseEvent onDataArrival(Data, bytesRead, dDate.Now)
        Catch
            RaiseEvent onError(Err.Description, Err.Number, dDate.Now)
            Exit Sub
        End Try
    End Sub
[/code]

It raises the error right here...

[code]
RaiseEvent onError(Err.Description, Err.Number, dDate.Now)
[/code]

Any ideas guys? im lost...

Sorry about the double post but coudl this have something to do with a Thread ending? I got an error message about a thread stopping but I dont remember to full error...
