Re: [twsocket] header too long HTTP_MIME_TOO_LONG
I will try my best to describe the problem I am experiencing a bit better;
My PHP side I have this:
On Dlephi side I have this:
var
aString1,aString2 : String;
begin
aString1 := HttpCli1.RcvdHeader.Values[xx: xx'];
aString2 := HttpCli1.RcvdHeader.Values[yy: yy'];
aLongString1 is very long, and using the document/content is not an option
in my case;
and this would require some parsing.
I am not sure how one should pass the data from PHP to Delphi;
Should I be setting some HTTP HEADERS on the PHP SIDE, or maybe some
setting I can make to the APACHE server to get past this ERROR.
Maybe I must specify some MIME TYPE? or is this done by the APACHE SERVER ?
I used WireShark to get the "HTTP_MIME_TOO_LONG" error by watching the
network traffic.
I did not receive any error on the APACHE server nor on the Delphi side;
I have also noticed that as soon as the data becomes too large, then no data
is returned from
the PHP at all;
Any ideas are welcome please.
$alist does hold a long list of SQL data.

[twsocket] ThrdSrvV2_1 and ICS V7
We have an application that is based on ThrdSrvV2_1, the example makes use of Two Threads, Client and Server; ThrdSrvV2_1 was part of the ICS for Delphi 7. We use the ThrdSrvV2_1 as a base, with ICS V7 and Delphi 2009. What we are experiencing is a thread Detach error, (Can not Detach from another Thread), this is when the Client Disconnects. This does not happen all the TIME, we can run up to 10 tests before the application will bomb with this error; I am not sure what is causing this, but it "seems" that it depends on the sequence that threads are finishing; I have notices that the ThrdSrvV2_1 is dated 2001; is there a NEW one ? Is there any ICS V7 sample that uses two Threads ? thanking you Wayne Forrest. -- 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] 'Cannot detach from another thread'
I am having a problem that I do not understand, what It means,
The Error message I receive is: *'Cannot detach from another thread'*
Here is my code, based on some example I got from ICS, the code below is in
my Main Unit.
{*
We have to attach client socket to this thread's context and then
process messages so that TWSocket events works.
}
procedure TClientThread.Execute;
begin
if not Assigned(WSocket) then
Exit;
{ Attach client socket to this thread
}
WSocket.ThreadAttach;
{ Signal main thread that we've attached socket to this thread
}
ThreadAttached := TRUE;
{ Now let main thread continue starting the connection.
}
{ This little avoid race condition.
}
Sleep(0);
{ Let's block on critical section already owned by main thread
}
EnterCriticalSection(FCritSect);
LeaveCriticalSection(FCritSect);
{ Then process messages until WM_QUIT message is posted.
}
{ TWSocket is event-driven. So even when used within a thread, we
}
{ have to have a "message pump". Any message pump will do and there
}
{ is one built in TWSocket, so use it !
}
WSocket.MessageLoop;
{ Be sure to have main thread waiting for termination before
terminating}
Sleep(0);
{ Detach the hidden window from within the thread
}
WSocket.ThreadDetach; //<<< ERROR Event Raised.

Re: [twsocket] HttpCli extract Header Variable together with php
Hello Francois, you are right, it is header lines that I am referring to, "Header-Name: value", ending with CRLF. I find it strange that If I use the above format, I am unable to extract the value using HttpCli1.RcvdHeader.Values['Header-Name']; If I use the following format, I am able to extract the value. *"Header-Name: Header-Name=aValue"* HttpCli1.RcvdHeader.Values['*Header-Name: Header-Name*']; Maybe my understanding is incorrect.

[twsocket] ICS and D2009 - Chinese data in Buffer.
Hello, I am experiencing a problem with ICS where the Receive buffer is an
array of char,
When I receive the data it is not what I expected, maybe my data sent is
wrong or the receiver end.
The code worked perfect with Delphi 7 but with Delphi 2009 it is failing;
In my Code I have replaced all occurrences of String with AnsiString, but
this has not solved my problem.
var
Buffer : array [0..1023] of char; //reception buffer of 1024 characters
begin
Len:= WSocket.ReceiveFrom(@Buffer, SizeOf(Buffer), Src, SrcLen);
Memo1.Lines.Add(' Data Received from'+StrPas(inet_ntoa(Src.sin_addr))+
':'+ IntToStr(ntohs(Src.sin_port))+'>>'+StrPas(Buffer));
The Buffer Contains this: Data Received from x.y.z:6109>>汣敩瑮举䵁E
I am expecting ASCII text yet I get the Chinese
Any help please.

What is the latest version The one on the CD or the Alpha 1 on the web ? 2. Is there any other version that we can use with D2009; our main concern is stability ? 3. What is most likely not to be stable in the V7 for D2009, as we only use the TCP and Http stuff?

[twsocket] ZOMBIE established connections "netstat -a"
Hello, I have "ZOMBIE" connections that remain active for some time. We accomplish this by connecting with a Cell phone to ICS, and remove the battery while we have an active TCP connection. Is there a way that we quickly determine such connections and clean them up.

Re: [twsocket] SMTP Client - Delete Temp files -
Ok that worked by I hit a "BRICK WALL" :-( ;
This is not related to ICS but the way that the Mail-Module Works.
Here is my Problem I am having.
(1'st Email)
(Trigger to Send Email)-->Class Fucntion to Send Email.
Event Mail Sent -->Delete Temp
Files
(2'nd Email)
(Trigger to Send Email)-->Class Fucntion to Send Email.
Event Mail Sent -->Delete Temp
Files
My problem is that the File List (TStrings) is LOST or not initialized since
it is not STATIC;
It seems to me to solve the PRoblem I will have to not use CLASS Functions;
Is there any other way; Like a STATIC Variable in Delphi 7;
I tried the {J+} const aFileList : TStrings = nil; {J-} but it did not WORK;

[twsocket] UDP Hole Punching
Has any one made a UDP Hole puncher with ICS ? Let A and B be the two hosts, each in its own private network; N1 and N2 are the two NAT devices; S is a public server with a well-known globally reachable IP address. 1. A and B each begin a UDP conversation with S; the NAT devices N1 and N2 create UDP translation states and assign temporary external port numbers 2. S relays these port numbers back to A and B 3. A and B contact each others' NAT devices directly on the translated ports; the NAT devices use the previously created translation states and send the packets to A and B If I were to implement the above, is it really that simple? or is there much more to it than that ? Any help appreciated, or alternatives, maybe a plugin / generic solution that can be incorporated. Our current setup is "Server on PC behind nat" and then client on Cell phone. We will have a lot of users not knowing how to do port forwarding. Thank you.

Re: [twsocket] Invalid Window Handle when Application Closed and ActiveConnections
It is a Bit Hard to Find the Exact Location of the Error; The Debugger goes into : Sysutils to Raise the LastOSError; System Error: 1400, invalid window handle. If I hit Ctrl+F3; to get the STACK TRace, there is nothing that is worthwhile to track. I have also tried adding this to the Application OnClose Event: procedure TMainForm.FormClose(Sender: TObject; var Action: TCloseAction); var i : Integer; begin i := WSocketServer1.ClientCount; for i := 0 to i - 1 do begin WSocketServer1.Client[i].Close; end; end; the above made no Difference.

Is there a Way that I can Detect the LastError Code for the Current Thread:
as in
if aThread.ErrorFree then begin
// do my send operations.
end;
Thank you.

[twsocket] Access Violation at Address 00000 - When Client App terminates
I have an Access Violation at address 0, I googled on this and found
that this means a reference to a null.
Basically I have implemented my Application based on "ThrdSrvV2_1" demo
project,
The problem happens as Follows: The Client connects to the Server, then
requests data,
I then Close the Client Application (Terminate / end task).
the server then runs into this Routine: I am not sure where the Error is
precisely, I think it is when the Windows Message gets processed.
inside the "Forms unit" of delphi.
Any Ideas.

Wilfried, thank you for the help,
the Function worked just perfect !

Re: [twsocket] Send Integer ?
I have no joy yet, maybe you can assist a bit more,
On the receiving side I have this in java:
~~
int ch1 = iStrm.read(); //read first byte
int ch2 = iStrm.read(); //read second byte
int ch3 = iStrm.read(); //read third byte
int ch4 = iStrm.read(); //read fourth byte
len = ((ch1 << 24) + (ch2 << 16) + (ch3 << 8) + (ch4));
//convert bytes to integer
System.out.println("LENGHT="+len);
on the Sending Side I have this ( ICS)
var
len,size : Integer;
begin
len := 4;
size := ImageStream.Size;
aThread.Send(@size,len);
~~
My old code with Indy was :
~~
aThread.Connection.WriteInteger(ImageStream.Size, true); // network byte
Order
