Re: [twsocket] THttpCli not returning?
Arno, I'm running with V7 here, although possibly not the latest iteration of it. Is there anything recently new to this component that may affect this functionality? Also, I don't have an accessible TimeOut parameter that I can set. Is this internal to the component only? Or is this a new feature?

Re: [twsocket] THttpCli not returning?
I must say what Arno is talking about I experienced too: the built-in timeout doesn't work (and I only do sync calls), this is why I created an external timeout to call the Abort. If the HttpCli component doesn't recieve anything it hangs forever.

Re: [twsocket] THttpCli not returning?
I work with Delphi 7 and the Timeout has never worked for me, I don't know if I was using it incorrectly but I was forced to put an external timeout because of this.

[twsocket] Receive log file text
Hi, Can someone please help me out w ith a sample of how to, send a log (text file) from client to the server? My connection is with ICSSLServer and ICSSSLClient. My client opens the connection and makes sure connection is always on. Log file is just a regular text file and not so big. I just need to receive the log file before closing restarting the client due the daily reboot routine. thanks in advance. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] Receive contents of remote text file over SSL

That works the same way as without SSL. And it depends on your protocol. Typically you send a request to the server telling him that you want to send a file. The request would include filename and filesize in bytes. When the server received the request it opens an filestream, turns off LineMode and sends back an OK-response or any error code. On receipt of the OK-response the client opens the file, reads from it into a small buffer i.e. 4-16 KB and sends the buffer content. The client sends subsequent data chunks from event OnDataSent until the file is completely sent. The server simply receives into a small buffer and writes buffer content to the filestream until filesize has been reached.

[twsocket] TWsocket connection error 10048

I have got to the bottom of the Error 10048 It seems that the order in witch you assign values to the TWSocket properties when you want to open a client is important - so now I can open and close the client heaps of times with out the error 10048 being raised :-) The code I was using looked like this TheTCPClientSocket-Proto = tcp; TheTCPClientSocket-Port= TCP_ClientPort; TheTCPClientSocket-Addr= TCP_ClientAddress; TheTCPClientSocket-LocalPort = TCP_ClientPort; TheTCPClientSocket-LocalAddr = 0.0.0.0; TheTCPClientSocket-Connect(); The correct code that works looks like this TheTCPClientSocket-Addr= TCP_ClientAddress; TheTCPClientSocket-Proto = tcp; TheTCPClientSocket-Port= TCP_ClientPort; TheTCPClientSocket-Connect(); Does anyone know why this is the case ???
