how to Execute application on server side and wait for completion

[carrera]

hi,

Is it possible to execute application (exe or cmd) on service side and wait for finish, before sending the file to client

 

 

Thanks for any advice

If it is a console app you can use CreateProcess. Or see here: http://forums.unigui.com/index.php?/topic/3529-webcmd-start-a-command-line-console-app-in-browser-interactive/?fromsearch=1

eu usso isso:

 

{CHAMA EXECUTAVEL PASSANDO PARAMETROS, ESPERA FINALIZACAO DO MESMO}

function ExecutaeAguarda(const FileName, Params:String; const WindowState: Word): boolean;

var

  SUInfo: TStartupInfo;

  ProcInfo: TProcessInformation;

  CmdLine:String;

begin

result :=false;

if (NOT FILEEXISTS(FileName)) and (pos('\',FileName)>0) then

   BEGIN

     alerta('Arquivo '+FileName+#13+'não foi encontrado!');

     exit;

   END;

 

  CmdLine := '"' + Filename + '"' + Params;

  FillChar(SUInfo, SizeOf(SUInfo), #0);

 

  With SUInfo do

   begin

    cb := SizeOf(SUInfo);

    dwFlags := STARTF_USESHOWWINDOW;

    wShowWindow := WindowState;

   end;

  Result := CreateProcess(nil,

                          PChar(CmdLine),

                          nil,

                          nil,

                          false,

                          CREATE_NEW_CONSOLE or NORMAL_PRIORITY_CLASS,

                          nil,

                          PChar(ExtractFilePath(Filename)),

                          SUInfo,

                          ProcInfo);

  if Result then

    begin

     WaitForSingleObject(ProcInfo.hProcess, INFINITE);

     CloseHandle(ProcInfo.hProcess);

     CloseHandle(ProcInfo.hThread);

    end;

end;

 

 

params :='"PARAM" "PARAM2" "PARAM3"';

ExecutaeAguarda(UniServerModule.ServerRoot+'\yourexe.exe',params,SW_NORMAL)   //SW_MINIMIZE SW_HIDE ....
