void __fastcall TMainForm::btSaveClick(TObject *Sender)
{
    TStreamWriter* writer;
 
    /* Create a new stream writer directly. */
    writer = new TStreamWriter("local_file.txt",
        false, TEncoding::UTF8, 1024);
 
    /* Store the title and then the text. */
    writer->WriteLine(edtTitle->Text);
    writer->Write(mmText->Text);
 
    /* Close and Free the writer. */
    delete writer;
}
 
void __fastcall TMainForm::btLoadClick(TObject *Sender)
{
    TStreamReader* reader;
 
    /* Create a new stream writer directly. */
    reader = new TStreamReader("local_file.txt",
        TEncoding::UTF8);
 
    /* Read the title and then the actual text. */
    edtTitle->Text = reader->ReadLine();
    mmText->Text = reader->ReadToEnd();
 
    /* Close and Free the writer. */
    delete reader;
