    Web scraping

    Morning all,
    Currently have Excel2000.
    Would like to scrape webpage into Excel (ALT_D_D_W) from the URL-
    http://newsite.tab.co.nz/racing/
    It comes back with error message "Returned no data try editing query"
    (ALT_D_D_E)
    Tried editing with no joy, can anyone out there overcome this challenge?

    Regards Mick Barry

    You can try SW Explorer Automation
    (SWEA)http://home.comcast.net/~furmana/SWIEAutomation.htm.

    The following example shows how to get a table from the
    http://newsite.tab.co.nz/racing/ Web site using SWEA. SWEAProject.htp
    was created by SWEA Visual Designer. SWEA designer contains Visual
    Table Extractor. The Table Data Extractor extracts tabular data from
    the Web pages. If a Web page contains repeating information patterns
    than the data can be transformed into ADO.NET DataTable object.

    public static void Main() {
    SWExplorerAutomation.Client.ExplorerManager explorerManager = new
    SWExplorerAutomation.Client.ExplorerManager();
    SWExplorerAutomation.Client.Scene scene;
    explorerManager.Connect(-1);
    explorerManager.LoadProject("SWEAProject.htp");
    explorerManager.Navigate("http://newsite.tab.co.nz/racing/");
    scene = explorerManager["Scene_0"];
    scene.WaitForActive(30000);
    System.Data.DataTable dataTable;
    dataTable =
    ((HtmlContent)(scene["HtmlContent_0"])).TableDataExtractor.DataTable;
    explorerManager.DisconnectAndClose();
    }

    The DataTable can be stored into text file (CSV) and loaded by Excel or
    Excel application can be called directly from the scraping program.

    In IE highlight the tabel you want to extract or click in the frame you
    want to extract the table(s) from and hit Ctrl-A to select all. Then
    hit Ctrl-C. Go to Excel and hit Ctrl-V. That will paste the table or
    all tables into your worksheet. You can work with these tables like
    with any other tables.
