I do not know how do you retrieve the line in a text file. I want to recover 1 in this txt file. #include <iostream> #include <string> #include <fstream> #include "sierrachart.h" #include <stdio.h> #include <time.h> using namespace std; SCDLLName("Test"); SCSFExport scsf_DTNS(SCStudyGraphRef sc) { if(sc.SetDefaults){ sc.GraphName="Test"; sc.StudyDescription="Test"; sc.FreeDLL = 1; sc.GraphRegion = 0; }//Fin de la fonction Defaut// ifstream Files("Z:\\Sierra_Chart\\Data\\Val.txt", ios::in);//Z:\\SC_Graphique_rithmic\\Data\\Val.txt" if(Files){ //sc.AddMessageToLog("File Open.", 1); string Lines; while ( getline(Files, Lines) ) { // ..... } Files.close(); return; }//Right else{ sc.AddMessageToLog("File Not Open.", 1); return; }//Wrong }//Fin de fonction// In Val.txt 1 // Line 1 How can i retrieved the line in the WHILE ? I don't Know ! |
