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..50000] 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
