EasyConfig C++ Class

 

Config files such as *.ini You'll see it's not hard at all to use it.

Please note that there are 2 constructors, an empty one that doesn't require any argument and another one that takes the file name.

If you declare an object without any file name, you'll have to use the SetFileName method.

 

Here's an exemple:

(cpp):

#include "stdafx.h"

 

using namespace std;

 

int main(int argc, char* argv[])

{

ConfigFile myIni;

 

myIni.SetFileName("C:\\Hax.txt");

 

cout << myIni.ReadStringValue("LOL", "value1").c_str() << endl;

 

    cout << "Writing int into value2..." << endl;

 

    myIni.WriteValue("LOL", "value2", 1337);

    cout << myIni.ReadIntValue("LOL", "value2") << endl;

 

    cout << "Writing float into value3..." << endl;

 

    myIni.WriteValue("LOL", "value3", 3.14f);

    cout << myIni.ReadFloatValue("LOL", "value3") << endl;

 

    return 0;

}

 

WriteValue is an overloaded function that works with float, int and strings which is actually what I needed.

The code launches a ConfigFileException when shit happens.

 

 

For exemple:

(cpp):

ConfigFile myIni;

 

cout << myIni.ReadStringValue("LOL", "value1").c_str() << endl;

 

 

In this code, we didn't set a file name. The code will launch an exception that contains,

The file name (In this case, it's ) And the error description To avoid unhandled...

 

 

Exceptions:

(cpp):

ConfigFile myIni;

 

try

{

cout << myIni.ReadStringValue("LOL", "value1").c_str() << endl;

}

catch( ConfigFileException e )

{

cout << "*** EXCEPTION CAUGHT ***"<< endl;

cout << e.fileName << endl;

cout << e.errMessage<< endl;

}

 

 

I  added the exceptions stuff today, so if you find anything i could add/correct, just say And now, the file you're all waiting for:

 

 

EasyCfg.cpp

(cpp):

#pragma once

 

#define FILE_NOT_EXISTING        "The file you tried to open doesn't exist"

#define FILENAME_NOT_DEFINED    "You didn't declare a file name"

#define NO_FILE_NAME            "<no File Name>"
