Duplicate data with Getdata

[reado]

I currently have a winsock control on a form listen for connection, once a connection has been established it starts to receive data from another application sending the data.
My problem is I send a large amount of data split up into chunks through to the listening winsock control, one after the other.
At the listening winsock control I sometimes get duplicate chunks of data and so receive more data than was actually sent.

I have checked this by writing the output to a file..please see below.

pstrData = ""
   sckTransactionServer(Index).GetData pstrData, vbString
 
  Open "D:\development\WebeXchange2\AuthXLoadBalancer\tcpipinput.txt" For Append As #2
      Print #2, pstrData
   Close #2

It looks as though the GetData buffer is not being emptied on the GetData call before the next DataArrival event is fired??

Help???

When sending data quickly, it gets 'stuck' together so lest say you sent the following

1
2
3
4
5
6
7

in a loop, the client may recieve this as

12
3
4
567

as you can see its merged together, you can combat this by using Packet Delimeters

Hope that helps

Hi,
First of all thanks for your reply. I dont think your answer isnt quite the answer to my problem, I am sending XML data and I know that the data can arrive seperate or all together so I handle that further in the program.
My problem is that I GetData on the DataArrival event and sometimes on the next DataArrival event I GetData again and some of the previous data is still in there.
So I send the following as part of say a 300 entry XML record at once

<DATA><NAME>Paul</NAME></DATA>
<DATA><NAME>Fred</NAME></DATA>
<DATA><NAME>Jo</NAME></DATA>

At the receiving end I sometimes get

<DATA><NAME>Paul</NAME></DATA>
<DATA><NAME>Fred</NAME></DATA>
<DATA><NAME>Fred</NAME></DATA>
<DATA><NAME>Jo</NAME></DATA>

Any ideas
Thanks for your help so far...
