I see your point - the other day I got the same result over and over again,
today the same code works fine. I'll have to remember to build "retry"
functionality into the system :)
BTW, just to clarify what was happening the other day, the following result
would end up with the variable 'msg' having data:
void __fastcall MyClass::ClientDataAvailable(TObject *Sender, WORD ErrCode)
{
AnsiString msg = ((TWSocketClient*) Sender)->ReceiveStr();
}
Whereas this code would result in the variable msg being empty:
void __fastcall MyClass::ClientDataAvailable(TObject *Sender, WORD ErrCode)
{
TWSocketClient* Client = dynamic_cast(Sender);
AnsiString msg = Client->ReceiveStr();
}

Bevan

In this case I think you're right, and I've been known to do that in the past as well - saves having to worry about implementing timeouts because I believe there's a timeout parameter for the Sync versions of the functions. > It is quite simple: I´m opening a query on a database, iterating through > the result set and have to send one mail for each record (= customer).

Yes, that's right, you can just run one command after the other, possibly with appropriate error checking as well.

[twsocket] FTPClient Upload/download size incorrect?
Using FtpTst demo, I upload a file from c:\dir, size 61,184. After upload, "size" indicates 60995. Download the same file, size is 61,440. Anybody know what's going on?

[twsocket] Need a simple SMTP example
Dear community, a critical situation forces me to implement a quick way for sending mailings with ICS components (all other stuff out there won't work properly, they told me). In fact, it is a rather simple scenario - walking through a customer database and sending SMTP mails to some customers, plain text and no HTML, but with one or two attachments (PDF files). It should be accomplished using Delphi 7, and we've currently installed ICS / SmtpProt v2.38. We'd like to upgrade to the most recent version next week, but work needs to be done right now :-( Can someone point me into the right direction for completing the required tasks by showing an example or directing me to some sample files?

Re: [twsocket] Throughput problem with TWSocket over a "long line"
Hello Tobias, > TCP/IP connection with high round trip times and small packet sizes If packets are < max MCU then Nagle will come in and will wait a while to see if you want to send a packet again. Nagle does this to try to concat packets to a larger one to fit into the max packet size. Specially if you use a command / ack protocol and packets are very small this will slow down a lot. Typically 4..5 packets per second in that case. To improve performance you can make your packets equal to the MTU, or switch Nagle off. There are some notes on Microsoft site about this. If you search for Nagle on MSDN you will find a lots information about that. They dont encourage to switch it off but in some cases (maybe yours) it is better. Note that you have to switch it of at both ends. oh hes: it is the TcpNoDelay option you have to switch on in TWSocket. > ~ 1.18 MB/s when using my application > ~ 1.2 MB/s when using the ICS FTP demo server > ~ 6.5 MB/s when using the Indy10 FTP demo server The ICS demo programs are not specifically written to improve speed. They are written to give a as mutch as possible clear for newcomers.

Re: [twsocket] WinSock error 10035 with TWSocketServer
Hello Bevan, It is normal that you receive an empty string once a while. Just exit the OnDataAvailable event in that case. When data is really ready to receive OnDataAvailable will fire again. About the 10035 yo dont have to worry. This is internally handled by TWSocket. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] udp multicast multiple packages -> TWSocket bug?
Hello, I did a quick look. It seems you start (or resume one from pool) a thread and give the received data to it. Probably you give data again to a thread that is still busy with the previous data.

When using a TWSocket derived application over an TCP/IP connection with high round trip times and small packet sizes (it is an 155 MBit ATM line) the throughput is very low. To check, if there is a general problem in my application I also checked the throughput with the FTP Server example and further with an FTP Server example from the Indy10 component package. The results for delivering a file over the line was: ~ 1.18 MB/s when using my application ~ 1.2 MB/s when using the ICS FTP demo server ~ 6.5 MB/s when using the Indy10 FTP demo server What can I do to improve the throughput in my application? Are there any known tweaks? I'd like to avoid changing to Indy because I like the clear and simple structured sources of ICS.
