write and read a TInt data from the file

How to write and read a TInt data from the file with symbian c++ code.

I want to write a TInt data to a file, then read the data from the file with c++.

My code below, but them error, who can tell me how to do that,thank you very much.


// Open file1
TInt tiDay;
tiDay = 1;
RFs fs;
TInt err;
fs.Connect();
_LIT(KMyFile,"c:\\file1");
RFile myFile;
//myFile.Open(fs,KMyFile,EFileShareExclusive|EFileWrite);
err = myFile.Open(fs,KMyFile,EFileShareExclusive|EFileWrite);
if (err == KErrNotFound) // file does not exist - create it
{
err=myFile.Create(fs,KMyFile,EFileShareExclusive|EFileWrite);
// Write to current file position: start of file
_LIT8(KWriteBuf,tiDay);
myFile.Write(KWriteBuf);

}

// Read from position 0: start of file
TBuf8<6> readBuf1;
myFile.Read(0,readBuf1); // readBuf1 is now "write "

TLex8 tlexData(readBuf1);
err = tlexData.Val(tiFromFile);
fs.Close();

I hope that take tiDay to file, then read it from the file.

Who can teach me.

Thank you very much.

        CDictionaryStore* iniFile = Application()->OpenIniFileLC(iEikonEnv->FsSession());
        RDictionaryWriteStream writeStream;
        writeStream.AssignLC(*iniFile, Application()->AppDllUid());

        writeStream.WriteInt16L( 0x666 );

        writeStream.CommitL();
        writeStream.Release();

        CleanupStack::PopAndDestroy(&writeStream);

        iniFile->CommitL();
        CleanupStack::PopAndDestroy(iniFile);

    CDictionaryStore* iniFile = Application()->OpenIniFileLC (iEikonEnv->FsSession());
    RDictionaryReadStream readStream;

    readStream.OpenLC (*iniFile,Application()->AppDllUid());

    badNumber = readStream.ReadInt16L();

    readStream.Close();

    CleanupStack::PopAndDestroy(&readStream); 
    CleanupStack::PopAndDestroy(iniFile);
