Re: [twsocket] Hi, I've a question
Hi Wilfried,
The problem is present because I test of data in the sent machine and the
data not is the same in Receive machine.
If I send 30Kb of data, in the other machine receive 7Kb only; and I don't
know what is the problem.
Send you part of code of application, but I know that information is sent
and not all receive.
Thanks again.
Bye.
Juan Pablo Franco
SENT MACHINE
overlaySocket.SendStr(Msg);
RECEIVE MACHINE:
procedure TFVisor.overlayListenDataAvailable(Sender: TObject; ErrCode: Word);
var
Buffer : array [0..5] of char;
Src: TSockAddrIn;
Len, SrcLen: Integer;
s:string;
begin
overlayListen.BufSize := 16384;
SrcLen := SizeOf(Src);
overlayListen.Receive(@Buffer, SizeOf(Buffer));
s:=StrPas(Buffer);
processMessage(s);
...
end;

[twsocket] Transfer with UDP
Hi Guillaume, I am using Tsocket UDP because I need transfer high speed data, but is more complicated because the sent machine send 720 strings in 4 seconds, and a string maybe contained large data. The most important in the application is the time, then receive data and process it must be fastest. Thanks. -- 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] Hi, I've a question
Francois, processMessage is used to parsing the receive string and put the data in an public array, this array is used for an other process that paint on the screen. Then I need full data in the string, if not is complete the paint process do incorrect picture. Thanks again and I will investigate this.

Re: [twsocket] Transfer with UDP
Again, If I use TCP, the time is over. I need transfer important data in little time. SENT MACHINE overlaySocket.SendStr(Msg); RECEIVE MACHINE: procedure TFVisor.overlayListenDataAvailable(Sender: TObject; ErrCode: Word); var Buffer : array [0..5] of char; Src: TSockAddrIn; Len, SrcLen: Integer; s:string; begin overlayListen.BufSize := 16384; SrcLen := SizeOf(Src); overlayListen.Receive(@Buffer, SizeOf(Buffer)); s:=StrPas(Buffer); processMessage(s); ... end; procedure processMessage(s: string); begin parsing message and save in array[]; end; in other process of RECEIVE MACHINE: begin while (don't stop application) do begin paint(array[])> pass throught end; end; IF I USE TCP IS PROBABLY THAT BUFFER COLAPSE THANKS AGAIN At 11:53 19/08/2005, you wrote: >Hello Juan, > >This can explain wy you loose data.

Re: [twsocket] Hi, I've a question
Hi Dan, I understand you, but the problem is that the paint process in Receive machine must paint at the same time that the paint process in the Sent machine. Here is the central point because the UDP protocol is asyncronous and I need two process in the same time in both machines. Juan At 13:33 19/08/2005, you wrote: >Yes, it looks that way.
