Save text from CList into file

Hi, guys;

I found a small problem with this. I thought it wasn't important but to
be honest it's becoming a real pain in the ass.

The question is the following:

I've got a Clist with several lines created in the Dialog. At the end
of the dialog, I want to save that text in a file. The code is this:

void CTranslator::OnEditorEnd()
{
    // TODO: Add your command handler code here

    char szFilter[] = " *.txt";
    CFileDialog FileDlg( TRUE, NULL, NULL, OFN_HIDEREADONLY, szFilter);
    if (FileDlg.DoModal() == IDOK)
    {
        try
        {

            CFile cf(FileDlg.GetPathName() + ".txt", CFile::modeCreate |
CFile::modeWrite);
            CString text;
            cf.Write("\r\n",4);
            for (int a = 0 ; a < line_t ; a++) // line_t is the last line in the
Clist
            {
                m_cLow.GetText(a, text);
                cf.Write(text, text.GetLength());
                cf.Write("\r\n", 4);
            }
            cf.Close();
        }
        catch (CFileException *e)
        {
            e->Delete();
            MessageBox("Error saving file");
        }
    }

}

The big problem is that, I don't know why, two blank spaces are added
at the beginning of each line in the file. It's more than an aesthetic
question because the lines saved are part of a code that the reader
doesn't understand when it finds the blank spaces.

Another less important question is how I can open a "save Dialog"
instead of a "open dialog", because doing it the way I do, the dialog
is an "open dialog".
