[twsocket] Http - access table or tabular sheet
Hi to all, Is it possible to make - access a table or tabular sheet to access an http site with ics components. Http sheet should have a very simple list, and should hold about 200 records, it is not needed to show this site like a regular http sheet: CurstNr OrderNr - 110 222 315 I would like to: 1. update this table 2. consult this table Thanks for any suggestions or reading material Greetings Werner -- 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] Http - access table or tabular sheet
Hello Werner, Sorry but your question is not clear, where is this tabbed data located ? if it is on a web page then simply download the page and read the tabs inside, ics will have nothing to do with this data analyzing. regards.

Re: [twsocket] Server problem (leaking memory)
Ok here is the core of the problem: The waitforsinglemessage solution worked
for the single thread for each connection case but since it is blocking,
cannot be used for the 32 clients per thread proxy. Here is the problem:
This is the worker thread:
void __fastcall THTTPThread::processServerThreadMessage(const MSG msg)
{
if(msg.message == WM_HTTP_CLIENT_THREAD_ATTACH)
{
httpServerClientClass *clientObject =
(httpServerClientClass*)msg.wParam;
clientObject-ThreadAttach();
PostThreadMessage(clientObject-serverThread-ThreadID,
WM_SYNCED, (WPARAM)clientObject, 0);
}
...
} // this function is called for every GetMessage
And this is the server thread:
void __fastcall httpServerThread::HTTPServerClientConnected(TObject *Sender,
TObject *Client, WORD Error)
{
httpServerClientClass *clientObject =
(httpServerClientClass*)Client;
clientObject-serverPermissions = serverPermissions;
clientObject-FServer = HTTPServer;
clientObject-URLPermissions =
serverPermissions-seekURLPermission(DEFAULTDOMAIN, true);
clientObject-affinityThread =
httpServerClientThreadManager-getHTTPThread();
clientObject-ThreadDetach();
while(!PostThreadMessage(clientObject-affinityThread-ThreadID,
WM_HTTP_CLIENT_THREAD_ATTACH, (WPARAM)clientObject, 0))
::Sleep(1);
MSG msg;
try
{
while(!Terminated GetMessage(msg, NULL, 0, 0))
{
if(msg.message == WM_SYNCED msg.wParam ==
(WPARAM)clientObject)
break; // NEVER COMES HERE!!
else
processServerThreadMessage(msg);
}
}
catch(ESocketException e)
{
}
catch(...)
{
}
//WaitForSingleObject(clientObject-attachedEvent, INFINITE);
HTTPServerClientPostConnect(clientObject);
}
//---
What I want is simple: I first want to have the thread attached before
exiting the function and moreover, I need other client run smoothly.
Hope you can help.
Best Regards,
SZ

This may not be your current problem, but it is a problem.
- destroy the client object fully
- have the FClientList routine run in the listener thread as it is
unprotected!
- Could you advise a shut down destruction routine (Pascal now ok).
Currently I've no idea how to do that, but I'm pretty sure it is
possible.
This stuff is rather tricky, my solution is in TWSocketThrdServer, but
of course many other solutions are possible.
Forgot to mention that I would derive a MT TWsocketServer first that
behaves
as I like. It often helps a lot to reduce the problem to the basics.
THttpServer is derived from TWSocketServer.

What do you suggest? What should I do? Would SendMessage work? But
there is no SendThreadMessage!
If you have one thread per connection you post your message, then
in a loop check a boolean flag that is set from within the worker
thread when ThreadAttach returned. If you have multiple connections
per thread you could use messages combined with Windows events or
other
sync-objects.
The latter design is demonstrated with TWSocketThrdServer that I made
to test ICS SSL in a multi-threaded environment. One connection per
thread
is demonstrated in demo ThrdSrv.
I saw your waitformultiplemessages design and it works with attach. But
there is a big problem with detach: In my code, triggersessionclosed
runs in
the context of worker thread!!! What I want:
- destroy the client object fully
- have the FClientList routine run in the listener thread as it is
unprotected!

Re: [twsocket] Http - access table or tabular sheet
This have nothing to do with ICS, ICS is here to get web page and put web page, the way your web server produce the document or retrieve it is not an ICS concern, this is more PHP/ASP. But everything you do with ASP/PHP can be done probably more easily with ICS HTTP server component and some Delphi code ! -- Contribute to the SSL Effort.

Re: [twsocket] Http - access table or tabular sheet
I have x webspace with my service provider. I want to create 1 dynamic page on it. - can I put an ics Http Server on it? You have to ask your service provider if you are allowed to run an executable and have it use publicly available TCP port (obviously different than the sandradt port 80 which is already in use by the webserver). or do I need to create other stuff first If you can't run your ICS/Delphi program, then you msut use whatever your provider allow. Probably something like ASP or PHP. - or do I need to create this Http Server on my computer, but then I need to run it my computer all the time, so users can access it? Yes you can. do that. You can easily be your own service provider. Not a big deal. You buy a fixed IP with DNS service and the required bandwidth and connect your own server. Then you do whatever you like, including writing your own server using Delphi and ICS components. You can also frequently drop your own computer in you provider computer room, using his network. You access it remotely to configure and maintain it. btw: This mailing list is for discussing ICS component. So you'are welcome to ask questions related to ICS use. For example questions about how to write your dynamic website with ICS or questions about how to access any website using ICS. Please keep on topic when asking. -- Contribute to the SSL Effort.

Re: [twsocket] No download from www.overbyte.be
I can't download anymore from Your WWW when cliking a link.
Eg. 'javascript:top.StartDownload('eng',%20'arch/ics.zip');'
Any idea of why ??
I checked the website. It works from here.
So the problem is probably at your computer. Check if you have cookies and
javascript enabled in
your browser. Check any misconfigured security product which might block
javascript or secondary
browser window.

What I want is simple: I first want to have the thread attached before
exiting the function and moreover, I need other client run smoothly.
Hope you can help.

This may not be your current problem, but it is a problem.
- destroy the client object fully
- have the FClientList routine run in the listener thread as it is
unprotected!
- Could you advise a shut down destruction routine (Pascal now ok).
Currently I've no idea how to do that, but I'm pretty sure it is
possible.
This stuff is rather tricky, my solution is in TWSocketThrdServer, but
of course many other solutions are possible.
Forgot to mention that I would derive a MT TWsocketServer first that
behaves
as I like. It often helps a lot to reduce the problem to the basics.
THttpServer is derived from TWSocketServer.

You say that you post a message to the worker thread to let it

What do you do until the worker thread has attached?? You cannot

What do you suggest? What should I do? Would SendMessage work? But

[twsocket] WSocketTS
Hello,
Assuming this is the official MT implementation for ICS, I am looking at the
below code:
{* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*}
function TWSocketThrdServer.ClientAttachThread(
Client: TWSocketThrdClient): TWsClientThread;
var
WaitRes : Longword;
H : array[0..1] of THandle;
begin
if Client.Handle 0 then
Client.ThreadDetach;
//LogDebug(IntToHex(Integer(Client), 8) + ' Main Thread Detached');
Client.FClientThread := nil;
Client.FServer := Self;
Result := AcquireThread;
H[1] := Result.Handle;
{ Wait until the thread has initialized its message queue }
if not Result.FReadyForMsgs then begin
H[0] := Result.FEventArray[cteiThreadReady];
WaitRes := WaitForMultipleObjects(2, @H, FALSE, Infinite);
if WaitRes = WAIT_FAILED then
raise Exception.Create('Wait failed ' +
SysErrorMessage(GetLastError))
else if WaitRes = WAIT_OBJECT_0 + 1 then
raise Exception.Create('Thread terminated while waiting');
end;
if not PostThreadMessage(Result.ThreadID,
WM_THREAD_ADD_CLIENT, Integer(Client), 0) then
raise Exception.Create('PostThreadMessage ' +
SysErrorMessage(GetLastError));
H[0] := Result.FEventArray[cteiClientAttached];
{ Wait until thread has attached client socket to his own context. }
WaitRes := WaitForMultipleObjects(2, @H, FALSE, Infinite);
if WaitRes = WAIT_FAILED then
raise Exception.Create('Wait client ThreadAttach ' +
SysErrorMessage(GetLastError))
else if WaitRes = WAIT_OBJECT_0 + 1 then begin
{ ThreadAttach failed due to the thread terminated, let's try again }
ClientAttachThread(Client);
Exit;
end;
if Assigned(FOnClientAttached) then
FOnClientAttached(Self, Client, Result);
//LogDebug(IntToHex(Integer(Client), 8) + ' W att ID: ' +
IntToHex(Result.ThreadID, 8));
end;
Now, does the end of this function (FOnClientAttached()) run in the worker
thread context? If not, what's the point in waiting with
waitformultiplemessages? Isn't only the PostThreadMessage enough? Francois,
could you enlight me? I am puzzled!
Best Regards,
SZ

WaitForMultipleOBJECTS, not messages! In my opinion the listener thread needs to be blocked while the client has no window (until the client has the new window allocated in the worker thread). If you would post a message from the worker thread to the listener thread you would need to process messages in the listener thread in order to receive that message which would not block the listener thread. WaitForSingleObject would work also but is dangerous. - First object is an event handle signaled in the worker thread after the Client has called ThreadAttach. - Second object is the thread handle so if the thread thread terminates a new attempt is made to attach to another thread. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Isn't only the PostThreadMessage enough?

In my opinion the listener thread needs to be blocked while the client has no window (until the client has the new window allocated in the worker thread). I cannot do this without modifying Francois' existing code and breaking compatibility. What about detroying the window in constructor? BTW, isn't this what ThreadDetach does?

[twsocket] TWSocket Question
Hi I've been using a TWSocket component successfully in one of my home automation plug-in applications for several weeks now by using line mode with a #13 line end. This was really easy to set up and get working. Now I want to use the TWSocket in another plug-in application, however the TCP server this connects to sends me a set size data block, it always starts with a MPSEND but ends with a checksum value. Could you tell me the best way to deal with this?

Re: [twsocket] TWSocket Question
Hello Philip, TCP server this connects to sends me a set size data block When you receive the size data block, then allocate memory for it, start concatenating data packets until you have received the exact size of the data. You have to save in a variable what is received, and what is left, to not receive more than the size. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Wednesday, March 22, 2006, 20:01, Philip Colley wrote: Hi I've been using a TWSocket component successfully in one of my home automation plug-in applications for several weeks now by using line mode with a #13 line end.

Currently this protocol is supported only in the THttpcli component. If you need it with TWSocket you would have to implement it by yourself. Not so difficult, since in HttpProt.pas you find all you need. Since a HTTP proxy is just another transparent proxy like Socks as well its use is not limited to the HTTP protocol. We already had a discussion about making it available in TWSocket, but nobody has done it so far. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html -- 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
