[twsocket] Update the browse
I just started to use ICS components and they appear very simple to use and powerfull, the sample help a lot for me that have a small knowlegment in HTTP protocol. I built a HTTP server using the ISC HTTPSever component and I have a question, I need update the browse by the server side without the browse send a request to me Is it possible? If yes how can I do this?

Technically, it is possible except the HTTP protocol has no provison for doing that. Usially, it is done using differents ways: 1) The browser request a periodic refresh because he received a HTML document containing the line: The number "2" above is the number of seconds the browse wait before requesting the given URL. 2) The server reply to some normal request with a never ending document. You either omit Conten-Length or use a huge value. Most browser analyse received document on the fly and display as it comes in. 3) Use a Java Applet or ActiveX object that establish a secondary connection to your server and do whatever they like with that connection. -- [EMAIL PROTECTED] http://www.overbyte.be -- 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
[twsocket] Twsocketserver
Hi guys, I do have a realtime application communicates to one side by USB and to the other acts as http server and/or TCPserver. I am trying to use ICS http server and everything seems OK. I use another free component of TCP server that has to run in different thread because of not event driven. Synchronizing makes me a lot of problems so I decided to use TCP server from ICS. My TCP communication isn't line oriented. Could I find any documentation to Twsocketserver or some example how to handle binary and maybe fragmented packets? I am already late with my project so I would prefer quick, maybe dirty help :-( Thanks in advance Igor -- 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

First, I mention record but I mean object. Usually I don't use anymore a set for a property mainly for two reasons. The first is that set are limited in the number of members. The second, and more important for me, is that sets doesn't works well with VFI, because you cannot "switch" a member without affecting the others. But last word is yours. >b.2) No opinion now.

We should think about a real scenario. I think that it is better for the moment that it remain as is, and then make a change when/if it is real needed to handle a real situation. Opinion from others reader? >d) I do not master the topic. Could you elaborate ? I know only what I red from RFC. This is what I understood. You can specify in the header what kind of encoding you can handle. This doesn't mean that you cannot receive a body encoded with a method not included in the Accept-Encoding. A second form is to specify the econding with a quality parameter, for example "gzip:1 deflate:0.9". With this you inform the server that you can handle both gzip and deflate but you prefer gzip. If you specify 0 as quality then it mean that you don't accept the encoding. Two particular encoding are "identity" and "*". You will never see this in the answer, only in the Accept-Encoding header. The first mean "no encoding" and the second "all others". So if you write "gzip:1 identity:0.2 *:0" should mean "I prefer gzip over identity, but doesn't accept any other encoding". Even this should be possible: "gzip:1 identity:0 *:0" i.e. "send me only encoded with gzip". This is the theory. Practically I made some test with IIS 5.1 and it seems ignore completly the quality. Actually I made some changes to disable the quality by default and use 0 as default quality for indentity and *. Coding with quality = 0 will not specified in Accept-Encoding if quality is not used.

Re: [twsocket] Twsocketserver
You could use a custom small header on every packet you send, i.e. first 2-4 bytes being the packet size, so when you receive data you add to a buffer and check if it reached the total size of the packet. If it has not, do nothing, if it has, complete the buffer and send the data packet to a processing routine. If the last data amount received exceeds the packet lenght you specified in the header, you can cut it and move it into a new clean buffer. I have some sources for that if you need - Original Message - From: "Igor Pokorny" <[EMAIL PROTECTED]> To: Sent: Monday, August 15, 2005 00:50 Subject: [twsocket] Twsocketserver > Hi guys, > > I do have a realtime application communicates to one side by USB and to > the other acts as http server and/or TCPserver.

[twsocket] Installing ICS under windows 3.11
Please help: I need to establish a program to program connection between two computers; one running windows XP, the other running Windows 3.11. I have Delphi 7 on the XP and Delphi 1 on the 3.11. I was going to install the ICS suite on the 3.11, but ICS uses long filenames which are not legal in 3.11. Is this the easiest way to establish this comms or is there a better way? The purpose of the link is, the 3.11 machine will be connected to a flight simulator cockpit I am building as the hardware interface, the XP machine will host MS flightsim and send/receive data to/from the hardware via the 3.11 machine. I am an absolute newby with programming sockets and TCP/IP, but I am an experienced delphi apps programmer. Many thanks in advance...

Re: [twsocket] Installing ICS under windows 3.11
If you can compile C++, you could check if you can use something out of the ptypes library. Since you only need communication and not all the overhead... How about setting up the communication thru SOAP? There *should* be a DOS implementation of SOAP out there somewhere... (perl on DOS? perl can do it). This is actually a good question to ask on experts-exchange.com. --Merijn On 8/15/05, Carl Hendry <[EMAIL PROTECTED]> wrote: > Please help: > I need to establish a program to program connection between two computers; > one running windows XP, the other running Windows 3.11.
