file.Close();
// Finished with user interaction: communicate parameters
and return
delete iAppUi->iFileName;
iAppUi->iFileName = fileName;
delete iAppUi->iText;
iAppUi->iText = text;
CleanupStack::Pop(2); // text, fileName
return ETrue;
}
I start by closing the file because that's no longer needed here. I then set the HBufC pointers
in the app UI to refer to the new strings and make sure that whatever was there before is
deleted. Finally, I pop both the new string pointers from the cleanup stack because they are
stored safely as member variables now.
The scene of processing now returns to my WriteFileL() function:
void CExampleAppUi::WriteFileL()
{
// Create a write stream on the file
RFileWriteStream writer;
writer.PushL(); // Writer on cleanup stack
User::LeaveIfError(writer.Replace(iCoeEnv->FsSession(),
// Write the text
writer
