    Where do I put the file to parse it in Visual Studio '08

    I'm trying to make a command line parser, but I'm not exactly sure
    where to put my file.txt file so that this thing can read it. The most
    logical place seemed to be the directory the project was in, but that
    didn't work.


    #include <fstream>
    #include <iostream>
    #include <string>
    #include <cstdlib>
    using namespace std;

    int main(){
    ifstream file;
    string fileName ="file.txt";
    file.open(fileN ame.c_str());
    if (!file){
    cout << "Failed to open file" << endl;
    return -1;
    }
    string newLine;
    while(std::getl ine(file, newLine)) {
    cout<<newLine<< endl;
    }
    return 1;
    }

      If you do not specify an absolute pathname to the file, the filename
      is relative to the current working directory when you start the
      project. I believe that in VS, by default, this is the directory the
      EXE ends up in -- which is your output directory (like "Release" or
      "Debug"), not the project directory. You could try putting it there.

      You could also go to your Project Properties -Configuration
      Properties -Debugging and change "Working Directory" to the
      directory that contains your file. VS will then change to that
      directory before starting your program if you run it from the IDE.

      Another option is to call SetCurrentDirec tory() before opening the
      file to set the current working directory to whatever.

      Yet another option is to specify the absolute path to the file in your
      program:

      string fileName ="c:\\wherever\ \file.txt";

      In any case, if the filename is a relative path it must be in the
      current working directory. Upon starting the program, VS sets the
      current working directory to the output path by default (I think). So
      pick any solution that puts the file in the current working directory.

      That said, this question is not on topic for comp.lang.c++. In the
      future you'll probably want to head to one of the microsoft.publi c.*
      newsgroups instead. This newsgroup is for specific questions about the
      syntax and semantics of the C++ language itself.

          Ya, I've tried most of those methods. I don't think this is a VS
          issue, the code might have some problems or something.

              Maybe. Your code looks relatively simple, though. I don't know what
              else to tell you. Perhaps as a test, try:

              #include <stdio.h>
              #include <string.h>
              #include <string>
              using namespace std;

              int main () {
              FILE *file;
              string fileName ="file.txt";
              file = fopen(fileName. c_str(), "rt");
              if (!file) {
              perror("Could not open file");
              return -1;
              }
              // ...
              }

              At least with fopen() you can get a reasonable error message (if it
              says "file not found", then you know the problem is that it's not in
              the path you think it is in).

              Incidently, if anybody knows how to get a reliable error message from
              an ifstream after a failed operation, I'd love to know. It's always
              kind of bothered me.
