help needed......

[joanntsc]

I have the following codes in my program to write data to file and read from file......

_LIT(KTestFile,"C:\\System\\apps\\testdata\\testdata.dat");
const TUint8* KTestData=_S8("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ\n");
const TInt KTestLength=36;
const TPtrC8 KTestDes(KTestData,KTestLength);


TBuf8<KTestLength+1> buf;
RFs TheFs;
RFile file;

User::LeaveIfError(TheFs.Connect());
User::LeaveIfError(file.Open(TheFs,KTestFile,EFileWrite));
RFile f=file;
RFileWriteStream out(f);
out.WriteL(KTestDes);
out.CommitL();

TInt iFileSize;
file.Size(iFileSize); // get the size of the file
out.Attach(file, iFileSize);
out.WriteL(KTestDes);
out.Close();

User::LeaveIfError(file.Open(TheFs,KTestFile,EFileRead));
RFile f=file;
RFileReadStream in(f);
in.ReadL(buf);
in.Close();
TheFs.Close();


Anyone know how to display the data inside the file on the screen if I want to?


million thanks in advance.......

Add this line in cpp file:

include <utf.h>

and this line in the mmp file:

LIBRARY charconv.lib

=|=|=|=|=|=|=|=|=|=|=|=|=|=|=|=|

After this line in your cpp file:

in.ReadL(buf);

write:

PrintOnScreen(buf)

now in your cpp file create this:

void CYourClassName::PrintOnScreen(TDes8& buf)
{
CnvUtfConverter::ConvertToUnicodeFromUtf8(text,buf);
iLog.LogL(text);
}

=|=|=|=|=|=|=|=|=|=|=|=|=|=|=|=|

Of course you need to inizialize iLog function in your project.
