MFC Example:Store and read with Ini file


Screenshot of notepad with some ini properties


I mostly use INI files to store program settings. For this, I use a properties class very often. Lately, I optimized it a little bit and I thought that maybe somebody else could also benefit from this class.

The properties class reads the INI file when its object is created. When no INI file exists, it creates it in the same location as where the main application exe is located. The INI file is named the same as the main exe but with the .ini extension. When the object is destroyed, the destructor makes sure that the data is stored in the INI file.

The reason I use INI files more than the registry is because when I have to give support, it is easier for the end user to mail me the INI file with all the settings than have him look into the registry. Sometimes end users are able to make changes to the settings in the INI file themselves. Having users editing the registry is more dangerous than editing an INI file in my opinion.

Using the code

To use this class, you have to add these lines to the stdafx.h:

Collapse Copy Code
#include "Properties.h"
extern CProperties prop;

Then add this line to the main application CPP file (myapp.cpp, for example) under the line "CMyApp theApp;":

Collapse Copy Code
CProperties prop;

Adding data to the INI file is easy. Just add a public member of type CString, int, or double to the header of CProperties (properties.h) and then add a line like the following in the constructor of CProperties (properties.cpp):

Collapse Copy Code
class CProperties  
    CString m_serverIp;
      t_props("Connection", "ServerIp", "", &m_serverIp));
                  ^             ^              ^               ^
      key name ___|value name __|default val __| data member __|

To compile the properties class, add the properties.(cpp/h) and inifile.(cpp/h) files to your project.

To access a property from your source code, you can type something like this.

Collapse Copy Code
void MyFunction()
    CString server = prop.m_serverIp;       // Get value
    prop.m_serverIp = "";           // Store value
