MS WinSock Control and receive-buffer...
Posted on 1998-03-03
I'm doing a VB 5.0 app. in wich I'm using a MS WinSock Control. I send queries to an Socket server, wich in its place chew on some data, and send them in a pre-designed format back to me. This is not any problem for my Socket client as long as the record I receive is less than 8192 bytes long (8k).
However, if it is, the tcpClient.DataArrival event stops after getting this amount, and I have to put in a "DoEvents" to get the rest of the record. The problem that arrises when I do this, is that I no longer can check wich recordtype the second "shipment" of data is, as it's the second part of a record.
Could this be a problem on the server-side, or can I somehow alter the receive-buffer? (I don't use any API-calls for my TCP/IP sessions).
On the server-side there is an C-application, running on an Dec Alpha-machine, and the send-buffer seems to be set to 15000 bytes. (The largest record I have is 14828 bytes).
The guys that has implemented this says they send the whole buffer in one go, so I should be getting 14828 bytes.
Does anyone have a clue what could be wrong, and maybe a hint on how to fix it?
