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();
}

to credit its author.
that would be me :-)
