When you start looping processmessages then your code can be reentered because messages ar pumped. This is also bad design. You can easy change your code event driven, just call Send there with the first record.

[twsocket] Strange
Hi, I'm experiencing a strange behavior of WSocket.Connect - WSocket.OnSessionConnected. I have 2 PC. One on which I develop my applications and a laptop. Both of them are Windows XP Proffesional with SP2 installed. The server my application is connecting is on the same 100 Mbps LAN as the 2 PC's above. From the firs PC, after calling WSocket.Connect, the connection is established very fast and OnSessionConnected is called. On the second PC, after calling Connect, nothing happens for about 30 seconds. The server the application is connecting does no receive any connection for the time specified above. So, to resume, on the first PC the connection is established right after WSocket.Connect and on the second PC the connection is established after an anoying delay. Does someone experience any similar situation? I have tried wsoTcpNoDelay on both server and client. No results.

Re: [twsocket] Strange
TnClient is behaving the same strange way. TnClient displays: Connecting to xxx.xxx.xxx.xxx and then Connected but the welcome banner of the server is displayed with 20-30 secs delay. On the other machine, the welcome banner is displayed right after Connected. My gues is it can be an OS bug, on the specific hardware platform (ethernet NIC, etc.). I've downloaded a packet sniffer, and 3 packets are captured when the connection is initialized: one from the client to the server, one from the server to the client and again, one from the client, and then the data transfer is delayed. The server is build around ucspi-tcp from http://cr.yp.to, on linux. On short, the tcpserver program is listening on a specified port and when a connection is established they launch an external program, rewriting input/output filedescriptors of that program on the incoming socket.
