Ini File

Try this.

void CMyAppUi::ReadIniFileL ()
{
  CDictionaryStore* iniFile=CDictionaryFileStore::SystemLC (iEikonEnv->FsSession ());
  if (iniFile->IsPresentL (KUidUserApp)) {
    RDictionaryReadStream stream;
    stream.OpenLC (*iniFile, KUidUserApp);

    idata=stream.ReadInt32L ();

    CleanupStack::PopAndDestroy ( /* stream */ );
  }
  CleanupStack::PopAndDestroy ( /* iniFile */ );
}

void CMyAppUi::WriteIniFileL ()
{
  CDictionaryStore* iniFile=CDictionaryFileStore::SystemLC (iEikonEnv->FsSession ());
  RDictionaryWriteStream stream;
  stream.AssignLC (*iniFile, KUidUserApp);

  stream.WriteInt32L (iData);

  stream.CommitL ();
  CleanupStack::PopAndDestroy ( /* stream */ );
  iniFile->CommitL ();
  CleanupStack::PopAndDestroy ( /* iniFile */ );
}

: Doesn't this save your data to the system ini file?! That's supposed to be
: banned (see KB at Symbiandevnet).

You are right - it does save it as a stream in the system.ini file.

For ER5, this was the prefered technique.  IIRC, this is how the Word
application does it (source code was supplied with the SDK).
I don't remember for ER6.0, but I think it was still allowed then.

: Instead you should open the ini file using CEikApplication::OpenIniFileLC.

For ER6.1, the functionality was removed from CAknAppUi, so you need
to use CEikAppUi to get it.

For ER7.0 it is there again.

So, it may/may not be the preferred technique, depending on what
platform you are using.

I use it on all platforms, but only to save 16 bytes of data (registration code
and GUI prefs).  It is not the place to store large amounts of data.  This
would need to go into a application specific config file.
