Ha iniziato a imparare a lavorare con i file. Mi sono imbattuto nel termine maniglia. La domanda è sorta dopo aver scritto il codice:

Dopo aver aperto il primo file news.csv, il programma imposta la variabile filehandle a 1. Successivamente, il programma ha aperto il secondo file news150901.csv e ha impostato la variabile filehandle a 2. Si scopre che il programma è ora lasciato con un valore di handle solo dall'apertura del secondo file. In altre parole, ho ucciso il valore dell'handle del primo file aperto. Cioè posso solo accedere ai dati/contenuti e chiudere il secondo file? Usare una variabile per memorizzare l'handle del file aperto è un errore? È necessario creare una variabile per l'handle per ogni file da aprire?

Quando si apre un file, si ottiene un "codice di accesso" ad esso - un handle. Finché non l'avete chiuso, potete lavorare con il file attraverso la sua maniglia, indipendentemente dal fatto che gli altri file siano aperti o meno.

P.S. Non dimenticate di chiudere i file (non sono chiusi nell'esempio).

Ho bisogno di uno script per una ricerca su Excel.
Descrizione.
Per 30 giorni dalle 8.00 alle 12.00 ogni giorno per stampare in file csv stampa apertura e prezzo di chiusura delle candele in questo intervallo di tempo.Periodo - su cui l'indicatore messo ma non più di un'ora.Indicatore stesso non dovrebbe visualizzare nulla e salvare in buffer.

Come rendere i cicli corretti?

            }
          }
      }      
  }

   string fileName=StringConcatenate(Symbol()," M",Period()," Tyrimas");
   string FileType=".csv";
   int handle;
   handle=FileOpen(fileName+FileType,FILE_WRITE|FILE_READ,";");
   if(handle!=INVALID_HANDLE)
   {
      FileSeek(handle,0,SEEK_END);
      FileWrite(handle,f_DayOfWeek,f_TimeCurrent,f_Open,f_Close,f_c_o,f_ABS_o_c);

   }
}

Ho dei dubbi sulla linea, quindi forse il ciclo non capisce l'inizio del giorno, ma funziona da zero bar.

for(int h=0;h<60/per*24;h++)

Aiutami.

Potete dirmi per favore come cancellare un oggetto da un grafico dei prezzi da un indicatore installato in una finestra del grafico?

La finestra del grafico ha sempre un indice di 0.

È difficile allegare il codice correttamente. C'è un pulsante speciale SRC nell'editor
