  Preference File Reader
  Submitted by



This Code Of The Day is a preference file reader. I've seen several different implementations of preference readers, but I've never been satisfied with there functionality. So, last year I wrote my own. I wanted to have something that would allow me to read from .reg files, ini files, memory blocks, or any other medium. This utility also needed to work on several platforms PC, Mac, PS2, and others. On top of all this, I wanted some cool features such as type safety, iterators, and abstraction from the storage medium to name a few. So, without further a due here is my implementation.

I provided three different versions of Preference storage objects.
  • CFilePref for reading and writing file based preference data such as .ini and .reg files.

  • CRegistryPref for reading and writing windows registry based preference data.

  • CMemoryPref for reading and writing to preference data in memory (this version is very basic, but one could easily be made to read and write binary data to specific memory locations such as flash memory. I've done it)


  • NOTES:
  • The GetValue methods are type safe, if you try to get a value using the wrong type the call will fail.
  • The SetValue methods will not create a value, they will only set an existing value. The call will fail if the value does not exist.
  • The CreateValue methods will not modify existing values, if the value exists the call will fail.
  • These rules apply to key methods as well.
  • All methods work on the current working key. The only exceptions to this rule are the SetKey method and the Save methods.
  • This is a very simple example of how to use the pref objects, the use of each object is exactly the same except for load and save calls.
    //     create a new preference file
    CFilePref filePref;

    filePref.CreateKey("MyRoot"); filePref.SetKey("MyRoot"); filePref.CreateValue("Some string", "strMyString"); filePref.Save("C:\\example.prf");

    // load an existing preference file CFilePref filePref;

    if(filePref.Load("C:\\example.prf")) { std::string strMyString;

    filePref.GetValue(strMyString, "strMyString"); }

    // open a file and save it to the registry CFilePref filePref;

    if(filePref.Load("C:\\example.prf")) { CRegistryPref regPref;

    regPref.CreateKey("HKEY_CURRENT_USER\\Software\\PreferenceTest"); regPref.SetKey("HKEY_CURRENT_USER\\Software\\PreferenceTest"); regPref.Insert(filePref); regPref.Save("HKEY_CURRENT_USER\\Software\\PreferenceTest"); }

    // Generic use of preference data void LoadPreferences( IPreferenceStore &refPrefData) { if(refPrefData.PushKey("MySubKey")) { refPrefData.GetValue(m_nMyIntVal, "nMyIntVal"); refPrefData.PopKey(); } }



    Feel free to use this source in any way you see fit, just don't forget to credit its author. that would be me :-)
