I'm in need of yahoo .csv file that has historic prices of stocks....I'm 
bewildered by the array of Indy Objects and their parts....
can anyone get me started...I know how to use indy to send/receive mail 
...but this seems far removed from that issue...
Thanks in advance...here is some \nSoftware code I've been using...but I 
need to do this in Indy...

    HTTPS1->LocalFile = file2Write; 
//tDiskfile->Text;
    urlAddress.sprintf("http://ichart.finance.yahoo.com/table.csv?s=%s&amp;d=%i&amp;e=%i&amp;f=%amp;g=d&amp;a=%i&amp;b=%i&amp;c=%i&amp;ignore=.csv 
",
      m_ticker->Text,
         end.MM(), end.DD(), end.YYYY(),
         start.MM(), start.DD(),start.YYYY()); //tURL->Text);
 SetCursorWait();
    HTTPS1->Get(urlAddress); //this downloads the file

Since you are trying to download a file from an HTTP server, you need to use 
the TIdHTTP component, ie:\

    urlAddress.sprintf("http://ichart.finance.yahoo.com/table.csv?s=%s&d=%i&e=%i&f=%i&g=d&a=%i&b=%i&c=%i&ignore=.csv", 
m_ticker->Text.c_str(), end.MM(), end.DD(), end.YYYY(), start.MM(), 
start.DD(), start.YYYY());

    TFileStream *strm = new TFileStream(file2Write, fmCreate);
    try
    {
        SetCursorWait();
        IdHTTP1->Get(urlAddress, strm); //this downloads the file
    }
    __finally
    {
        delete strm;
    }
