Re: [twsocket] TWsocket server client list Error

Hello Miguel, BGException is background exception. It comes from the message pump. This means it can come also from your code in one of the TWSocket events. To test put them all in a exception block until you found the error (if it is over there of course). Socket operation on a non socket means

Re: [twsocket] TWsocket server client list Error

Thank you for the answer Wilfried Im following your suggestios and I will test the Wsockets events today with try .. except blocks to try to find the error. However I want to ask something to, Is there a theory for the connections without IP and PORT that shows the TWsocketServer.client[i]?

Re: [twsocket] TWsocket server client list Error

Yes we have the same problem even though no exceptions are raised. This occurs with high traffic--especially sockets disconnecting with errors/abort. Regards, SZ - Original Message - From: Miguel Cañas [EMAIL PROTECTED] To: twsocket@elists.org Sent: Thursday, October 05, 2006 4:37 PM

Hello Fastream, But if a client disconnect with an error in high traffic, which events are you logging ? Seems a wierd problem to me... --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket

Re: [twsocket] TWsocket server client list Error

It seems the Client[] is not up to date. Perhaps we should remove the client from there when the disconnect signal is received? (not when the object is destroyed?) Best Regards, SubZero - Original Message - From: Wilfried Mestdagh [EMAIL PROTECTED] To: ICS support mailing

[twsocket] MD5 check needed ?

Hello, I'm writting a small C/S protocol. It includes sending/receiving database records. Would you suggest to send and check a MD5 checksum? May be it is OK to live with this overhead only upon database write requests? Arno Garrels -- To unsubscribe or change your settings for TWSocket

Hello Arno, AFAIK TCP already does CRC per packet so MD5 may be a bit expensive (doing additionally). Regards, SZ On 10/5/06, Arno Garrels [EMAIL PROTECTED] wrote: Hello, I'm writting a small C/S protocol. It includes sending/receiving database records. Would you suggest to send and check

Hello Arno, What happens in ICS when a corrupted packet has been received? Is DataAvailable being triggered with an error 0 ? I assume you use TCP. No need for additional check. I never have seen a corrupt packet in TCP. Even not on radio networks where there is planty of noise. If I recall

Re: [twsocket] MD5 check needed ?

Hello Arno, I wasn't sure about how Winsock/ICS handles simple data corruption. What would happen if it happens? Packets are resent. The amount of packets is depending the size of the receive window. If memory serve the receive window (where TCP send ACK) can be till 8 kb. --- Rgds, Wilfried
