what is the right way to parse JSON returned datetime field?

function updateChat(supplier_id, user_id, spantag) {
    $.ajax({
        type: "POST",
        url: "AjaxService/ChatService.asmx/GetChatBySupplierID",
        data: "{'supplier_id':'" + supplier_id + "', 'user_id':'" + user_id + "'}",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            var result = ($.parseJSON(response.d));

            var str="";
            for (var i = 0; i < result.length; i++) {
                str += "[" + parseJSONDate(result[i].chat_create_dt) + " " + result[i].usr_fname + "] " + result[i].chat_text;
                str += "
";
            }
            $("#" + spantag).html(str);

            setTimeout(function () {
                updateChat(supplier_id,user_id, spantag)
            }, 3500);

        }
    });
}


function parseJSONDate(jsonDate) {
    var d = parseFloat(jsonDate.slice(6, 19) );
    return new Date(d).format("MM/dd/yyyy hh:mm:ss tt");        
}

FileHandler to process binary field

{
    public void ProcessRequest(HttpContext context)
    {

        HttpResponse Response = HttpContext.Current.Response;
        HttpRequest Request=HttpContext.Current.Request;
        Response.Expires = 0;
        Response.Cache.SetCacheability(HttpCacheability.NoCache);

        if (Request.QueryString["fid"] != null)
        {
            ProductItem pi= new ProductItemRepository().GetById(Request.QueryString["fid"]);

            if (pi != null && pi.pi_image != null && pi.pi_file_name != null)
            {
                Response.Clear();
                Response.AddHeader("Content-Disposition", "attachment;filename=" + pi.pi_file_name.Trim());
                Response.ContentType = "application/octet-stream";

                byte[] buffer = pi.pi_image.ToArray() as byte[];

                if (Request.QueryString["t"] != null)
                {
                    string t=Request.QueryString["t"];
                    int n;
                    Int32.TryParse(t, out n);
                    if (n == 1)
                    {
                        //Converts the byte array to memory stream, then resize the image, then convert back
                        using (MemoryStream ms = new MemoryStream(buffer))
                        {
                            using (Image image = Image.FromStream(ms))
                            {

                                    img.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
                                    buffer = stream.ToArray();
                                }

Linq to Sql: Upload binary file

Aneef has a great tutorial on uploading binary files to the db using Linq.  http://www.aneef.net/2009/01/16/uploading-binary-files-or-images-using-linq-to-sql/comment-page-1/#comment-100

Here’s my version using only Linq.

protected void btnUpload_Click(object sender, EventArgs e)
{     
    if (fuFileUploader.HasFile && fuFileUploader.PostedFile.ContentLength > 0)
    {
        string path_file_name = fuFileUploader.PostedFile.FileName;
        string ext = Path.GetExtension(path_file_name).Replace(".", "");
        string file_name = Path.GetFileNameWithoutExtension(path_file_name);
        string file_title = txtFileTitle.Text.Trim();
        HelperDataClassesDataContext db = new HelperDataClassesDataContext();

        try
        {
            byte[] file_byte = fuFileUploader.FileBytes;
            Linq.Binary file_binary = new Linq.Binary(file_byte);

            ControlDocument cd = new ControlDocument
            {
                guid = Guid.NewGuid(),
                file_ext = ext,
                file_nm = file_name.Trim(),
                file_title=file_title,
                file_bin = file_binary,
                is_active = true,
                upload_page_type = rblLocation.SelectedValue,
                upload_dt = DateTime.Now,
                upload_by = UtilUniverse.Common.CurrentUserLogin.Trim()
            };

            db.ControlDocuments.InsertOnSubmit(cd);
        }
        finally
        {

            db.SubmitChanges();
        }
    }

}

Onion and his ways!

My dog Onion barfed on our carpet today.  What am I supposed to do?  I was ready to put him in his cage, but he was so quiet that I left him playing in the sun…more like lying in the sun.

Onion in his killer stance!

On Oct 25 – Ordination “Bouh”

The word “Bouh” means a lot to a family who follows “Theravada Buddhism”.  I did this to thank my parents and oh, were they so proud to be parents.  In my heart I did the best thing any child could do for their parent, family, and friends.  It’s a small sacrifice I’m willing to make.  Here’s my schedule as a monk.  I was there for two weeks-all the vacation I had left.

Schedule

4:30 AM – Wake up and get ready to chant
5:00 AM – Chant
6:00 AM – Meditate
7:00 AM – Breakfast
8:00 AM – Relax, read, meditate, clean, chores
11:00 AM – Lunch
