A Small Class to Read INI File


A small class to read INI File, only has 4 methods: ReadInteger, ReadFloat, ReadBoolean, ReadString.

Introduction

I have written two classes CIniReader and CIniWriter. They are used to read and write .Ini files. They only have four methods, and are very simple and useful.

IniReader.h

#ifndef INIREADER_H
#define INIREADER_H
class CIniReader
{
public:
 CIniReader(char* szFileName); 
 int ReadInteger(char* szSection, char* szKey, int iDefaultValue);
 float ReadFloat(char* szSection, char* szKey, float fltDefaultValue);
 bool ReadBoolean(char* szSection, char* szKey, bool bolDefaultValue);
 char* ReadString(char* szSection, char* szKey, const char* szDefaultValue);
private:
  char m_szFileName[255];
};
#endif//INIREADER_H

IniReader.cpp

#include "IniReader.h"
#include <iostream>
#include <Windows.h>

CIniReader::CIniReader(char* szFileName)
{
 memset(m_szFileName, 0x00, 255);
 memcpy(m_szFileName, szFileName, strlen(szFileName));
}
int CIniReader::ReadInteger(char* szSection, char* szKey, int iDefaultValue)
{
 int iResult = GetPrivateProfileInt(szSection,  szKey, iDefaultValue, m_szFileName); 
 return iResult;
}
float CIniReader::ReadFloat(char* szSection, char* szKey, float fltDefaultValue)
{
 char szResult[255];
 char szDefault[255];
 float fltResult;
 sprintf(szDefault, "%f",fltDefaultValue);
 GetPrivateProfileString(szSection,  szKey, szDefault, szResult, 255, m_szFileName); 
 fltResult =  atof(szResult);
 return fltResult;
}
bool CIniReader::ReadBoolean(char* szSection, char* szKey, bool bolDefaultValue)
{
 char szResult[255];
 char szDefault[255];
 bool bolResult;
 sprintf(szDefault, "%s", bolDefaultValue? "True" : "False");
 GetPrivateProfileString(szSection, szKey, szDefault, szResult, 255, m_szFileName); 
 bolResult =  (strcmp(szResult, "True") == 0 || 
		strcmp(szResult, "true") == 0) ? true : false;
 return bolResult;
}
char* CIniReader::ReadString(char* szSection, char* szKey, const char* szDefaultValue)
{
 char* szResult = new char[255];
 memset(szResult, 0x00, 255);
 GetPrivateProfileString(szSection,  szKey, 
		szDefaultValue, szResult, 255, m_szFileName); 
 return szResult;
}

IniWriter.h

#ifndef INIWRITER_H
#define INIWRITER_H
class CIniWriter
{
public:
 CIniWriter(char* szFileName); 
 void WriteInteger(char* szSection, char* szKey, int iValue);
 void WriteFloat(char* szSection, char* szKey, float fltValue);
 void WriteBoolean(char* szSection, char* szKey, bool bolValue);
 void WriteString(char* szSection, char* szKey, char* szValue);
private:
 char m_szFileName[255];
};
#endif //INIWRITER_H

IniWriter.cpp

#include "IniWriter.h"
#include <iostream>
#include <Windows.h> 
CIniWriter::CIniWriter(char* szFileName)
{
 memset(m_szFileName, 0x00, 255);
 memcpy(m_szFileName, szFileName, strlen(szFileName));
}
void CIniWriter::WriteInteger(char* szSection, char* szKey, int iValue)
{
 char szValue[255];
 sprintf(szValue, "%d", iValue);
 WritePrivateProfileString(szSection,  szKey, szValue, m_szFileName); 
}
void CIniWriter::WriteFloat(char* szSection, char* szKey, float fltValue)
{
 char szValue[255];
 sprintf(szValue, "%f", fltValue);
 WritePrivateProfileString(szSection,  szKey, szValue, m_szFileName); 
}
void CIniWriter::WriteBoolean(char* szSection, char* szKey, bool bolValue)
{
 char szValue[255];
 sprintf(szValue, "%s", bolValue ? "True" : "False");
 WritePrivateProfileString(szSection,  szKey, szValue, m_szFileName); 
}
void CIniWriter::WriteString(char* szSection, char* szKey, char* szValue)
{
 WritePrivateProfileString(szSection,  szKey, szValue, m_szFileName);
}

Main.cpp

#include "iostream"
#include "IniWriter.h"
#include "IniReader.h"
int main(int argc, char * argv[])
{
 CIniWriter iniWriter(".\\Logger.ini");
 iniWriter.WriteString("Setting", "Name", "jianxx");   
 iniWriter.WriteInteger("Setting", "Age", 27); 
 iniWriter.WriteFloat("Setting", "Height", 1.82f); 
 iniWriter.WriteBoolean("Setting", "Marriage", false);  
 CIniReader iniReader(".\\Logger.ini");
 char *szName = iniReader.ReadString("Setting", "Name", "");   
 int iAge = iniReader.ReadInteger("Setting", "Age", 25); 
 float fltHieght = iniReader.ReadFloat("Setting", "Height", 1.80f); 
 bool bMarriage = iniReader.ReadBoolean("Setting", "Marriage", true); 
 
 std::cout<<"Name:"<<szName<<std::endl
   <<"Age:"<<iAge<<std::endl 
   <<"Height:"<<fltHieght<<std::endl 
   <<"Marriage:"<<bMarriage<<std::endl; 
 delete szName;  
 return 1;   
}
