Symbian下ini文件操作

Symbian下ini文件的操作

程序中的一些配置信息，可以利用ini文件存储。同时存储到安装程序的私有路径下面。

_LIT(KtxDicFileName ,"settings.ini" );

const TInt KRegistrar = 2;

const TInt KUsername = 3;

const TInt KPassword = 4;

//读取
void LoadSettingValuesL()
{
// load values into iSettings
TFileName path;
TFileName pathWithoutDrive;
CEikonEnv::Static()->FsSession().PrivatePath(pathWithoutDrive);
// Extract drive letter into appDrive:
#ifdef __WINS__
path.Copy(_L("c:"));
#else
RProcess process;
path.Copy( process.FileName().Left(2) );
#endif
path.Append(pathWithoutDrive);
path.Append(KtxDicFileName);
// Open the dictionary store
CDictionaryStore* aDictstore = CDictionaryFileStore::OpenLC(
CCoeEnv::Static()->FsSession(), path, TUid::Uid(0x0001)); //TUid::Uid(0x0001) ini文件标识
RDictionaryReadStream in;
in.OpenLC(*aDictstore, TUid::Uid(KUsername));
TBuf16<100> aLockedString;
aLockedString.Delete(0, aLockedString.Length());
in >> aLockedString;
CleanupStack::PopAndDestroy();
CleanupStack::PopAndDestroy(1);// aDictstore
CAknInformationNote* note = new (ELeave) CAknInformationNote;
note->ExecuteLD(aLockedString);
return EFalse;
}

//存储
void SaveSettingValuesL()
{
// store values from iSettings
TFileName path;
TFileName pathWithoutDrive;
CEikonEnv::Static()->FsSession().PrivatePath(pathWithoutDrive);
// Extract drive letter into appDrive:
#ifdef __WINS__
path.Copy(_L("c:"));
#else
RProcess process;
path.Copy( process.FileName().Left(2) );
if(path.Compare(_L("c")) || path.Compare(_L("C")))
CEikonEnv::Static()->FsSession().CreatePrivatePath(EDriveC);
else if(path.Compare(_L("e")) || path.Compare(_L("E")))
CEikonEnv::Static()->FsSession().CreatePrivatePath(EDriveE);
#endif
path.Append(pathWithoutDrive);
path.Append(KtxDicFileName);
CDictionaryStore* aDictStore = CDictionaryFileStore::OpenLC(
CCoeEnv::Static()->FsSession(), path, TUid::Uid(0x0001));
RDictionaryWriteStream out;
out.AssignLC(*aDictStore, TUid::Uid(KRegistrar));
_LIT( KLOOCKED, "maria" );
out << KLOOCKED();
out.CommitL();
CleanupStack::PopAndDestroy();
RDictionaryWriteStream out2;
out2.AssignLC(*aDictStore, TUid::Uid(KUsername));
_LIT( KLOOCKED2, "zhang" );
out2 << KLOOCKED2();
out2.CommitL();
CleanupStack::PopAndDestroy();
aDictStore->CommitL();
CleanupStack::PopAndDestroy(aDictStore);
}

一些数据通过流方式的读取
// String
TBuf<100> iText;
aStream >> iText;

// Integer
TInt iVolume;
iVolume = aStream.ReadInt32L();

// Boolean
TBool iBinary;
iBinary = aStream.ReadInt16L();

// Ip address
TInetAddr iIpAddress;
iIpAddress.SetAddress(aStream.ReadUint32L());

// Time
TTime iTime;
TInt64 time;
aStream >> time;
iTime = TTime(time);
