    reading properties of uploaded files

    I was wondering if anyone had been playing around with reading the properties of uploaded files (ie. geo-codes, dates, etc. of uploaded image files).

    Dear mulmad,
     
    Please refer to the highlighted code:

    <%@ Page Language="C#" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <script runat="server">
        void InsertMsg(string msg)
        {
            ListBoxEvents.Items.Insert(0, msg);
            ListBoxEvents.SelectedIndex = 0;
        }

        void Attachments1_AttachmentAdded(object sender, AttachmentItemEventArgs args)
        {
            InsertMsg(args.Item.FileName + " has been uploaded.");
        }

        void ButtonDeleteAll_Click(object sender, EventArgs e)
        {
            InsertMsg("Attachments1.DeleteAllAttachments();");
            Attachments1.DeleteAllAttachments();
        }
        void ButtonTellme_Click(object sender, EventArgs e)
        {
            ListBoxEvents.Items.Clear();
            foreach (AttachmentItem item in Attachments1.Items)
            {
                InsertMsg(item.FileName + ", " + item.FileSize + " bytes.");
                //Copies the uploaded file to a new location.
                //item.CopyTo("c:\\temp\\"+item.FileName);
                //You can also open the uploaded file's data stream.
                //System.IO.Stream data = item.OpenStream();
            }
        }
    </script>

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">

                <p>
                    Google's GMail has a nice way of allowing you to upload multiple files. Rather than
                    showing you 10 file upload boxes at once, the user attaches a file, you can click
                    a button to add another attachment.
                </p>

                </CuteWebUI:UploadAttachments>
                <br />

    Thank you for asking
