Hi guys,

There are multiple clients connected to my server, but the correct response does not always go to the correct Client, am I doing something wrong or am I suppose to use other components ?

See my code below :

Thanks !!

Pieter



CLIENT :

procedure TfrmMain.Button1Click(Sender: TObject);
var
  sResponse, sService : String;
  PDIni : TIniFile;
  iCounter : Integer;
  AStream : TStringStream;
begin
  {Read from INI File}
  PDIni := TIniFile.Create(ExtractFilePath(ParamStr(0) + 'conf\client.ini');

  iCounter := 1;

  try
    IdTCPClient1.Host := edtHost.Text;

    try
      IdTCPClient1.Port := StrToInt(edtPort.Text);
    except
      IdTCPClient1.Port := 7778;
    end;

    with IdTCPClient1 do
    begin

      Repeat
        sService := PDIni.ReadString('services', 'service_' + IntToStr(iCounter), '');

        Connect;

        while Connected do
        begin
          try
            AStream := TStringStream.Create('');

            WriteLn('service_status');
            WriteLn(sService);

            sResponse := ReadLn;

            mmLog.Lines.Add(sResponse);

            iCounter := iCounter + 1;

            AStream.Free;
          finally
            Disconnect;
          end;
        end;
      Until
        PDIni.ReadString('services', 'service_' + IntToStr(iCounter), '') = '';
    end;
  except
  end;
end;





SERVER :

procedure TMonitor.IdTCPServer1Execute(AThread: TIdPeerThread);
var
  sRequest, sStatus : String;
begin
  try
    with AThread.Connection do
    begin
      try
        Repeat
          sRequest := ReadLn;

          if SRequest = 'service_status' then
          begin
            sServices := ReadLn;

            sStatus := GetServiceStat(PChar(sServices));

            if ((sStatus = 'UNKNOWN') or (sStatus = 'STOPPED')) then
            begin
              sStatus := 'N';
            end
            else if (sStatus = 'PAUSED') then
            begin
              sStatus := 'P';
            end
            else if ((sStatus = 'START/PENDING') or (sStatus = 'STOP/PENDING') or
              (sStatus = 'CONTINUE/PENDING') or (sStatus = 'PAUSE/PENDING')) then
            begin
              sStatus := 'B';
            end
            else
            begin
              sStatus := 'Y';
            end;

            WriteLn('[' + sServices + '][' + sStatus + ']');
          end;
        Until
          sRequest = '';
      finally
        Disconnect;
      end;
    end;
  except
  end;
end;

   On the Server you should have TIdTCPServer component.

   Then add on the form TIdThreadMgrDefault VCL - found on Indy Misc tab. Select the TCP server and it has propery ThreadMgr - select the TIdThreadMgrDefault object there.

Hi Ivanov,

Thanks for the quick reply !!

Sorry, I forgot to mention that I do have a IdThreadMgrDefault Component in my Service, and have selected it in the IdTCPServer's Object Inspector.

Thanks

Pieter
