run bat

[robinhodemorais]

Looking for how to run a stick with a single topic from that topic http://forums.unigui.com/index.php?/topic/3356-how-to-call-a-executable-file-on-server-side-within- unigui / where mhmda passes a procedure to execute, but I'm trying to implement it in my application and I'm not getting it ...
when I'm in the development environment running autonomously, I need to execute a stick that is at the root of the root, this type of stop starts the service node of the service, or what I notice is that it appears quickly or that closes but I I can see something.

in the bat file is in the following configuration

cd E: \ Delphi Projects \ socket
server.js node

bat name startNodeJS.bat

Starting an exe is a purely delphi language solution (no UniGUI).
It all depends on whether you need a return output from running the process.
In the latter case you have to use a semaphores management (also via file).

However I have used it in UNIGUI in this way:

// call
var
   NameExec     : string;
   NameFileJSON : string;
   rc       : word;
begin
    // exec process
    if dmDataset.ExecFile(NameExec, NameFileJSON, rc) then begin
       // timer OnThreadTerminate type TUniTimer for file response
       OnThreadTerminate.Enabled := True;
    end;        
end;

// function in Datamodule
function TdmDataset.ExecFile(const sComand, sParameter : string; var rc : word) : boolean;
var
   SI                        : TStartupInfo;
   PI                        : TProcessInformation;
   sCmd                    : string;
begin
   Result             := True;

   FillChar(SI, SizeOf(SI), 0);
   SI.cb := SizeOf(SI);
   SI.wShowWindow := SW_SHOWMINNOACTIVE;

   sCmd := sComand;
   if sParameter > '') then sCmd := sCmd + ' ' + sParameter;

   if (Not CreateProcess(Nil, PChar(sCmd), Nil, Nil, False,
             Normal_Priority_Class, Nil, Nil, SI, PI)) then begin
      rc     := GetLastError;
      Result     := (rc = 0);
      exit;
   end;

   CloseHandle(PI.hThread);
end;

procedure OnThreadTerminateTimer(Sender: TObject);
var
   FFolder     : string;
   Sr          : TSearchRec;
   FileDownload: string;
   SearchStr   : string;
begin
   // Response dir     
   FFolder := IncludeTrailingPathDelimiter(UniMainModule.Configurazione.PathLocal);

   SearchStr    := '*.json';

   if SysUtils.FindFirst(FFolder + SearchStr, faAnyFile, Sr) = 0 then
   begin
      repeat
         if Sr.Attr and faDirectory = 0 then begin
            if UpperCase(ExtractFileName(ChangeFileExt(Sr.Name, ''))) = 'RESPONSE' then begin
               // fistr disable
               OnThreadTerminate.Enabled := False;

               // action business -- download -- other ---
               UniSession.SendFile(IncludeTrailingPathDelimiter(UniMainModule.Configurazione.PathLocal) + ExtractFileName(Sr.Name), FileDownload);

               // send message
               dmToast.Success('Download. Scarico eseguito.');

               Break;
            end;
         end;
      until SysUtils.FindNext(sr) <> 0;
      SysUtils.FindClose(sr);
   end;

I did the tests with this function but I couldn't make it work, it gives error

 

 

[robinhodemorais]

WinExec ('e:\Robinho\webSocket\startNodeJS.bat', SW_SHOW);

in a test in vcl it executes, but that same command by unigui does not execute the command

how do i call a stick or pass a command with that function you did?

UNIGUI NEED IN EXE MODE, NOT ISAPI DLL , NOT SEVICE MODE,

AND NEED PATH AND FILE  Access rights.
