Time Management Tips #9 - Pair Up

AddThis Social Bookmark Button
What's the best way to do it? Together. Pair up. Time management tips #9 is pair up.  Paring up simply means find somebody that will work with you on something, rather than go it alone.   When you pair up, you create a team of capabilities and you learn how to love the things you might otherwise hate.  Worst case, you at least make doing what you don’t enjoy, more fun.  Best case, you find a new passion for something you didn’t know you had. We
all have things to do that we're not great at, or slow us down.  Maybe it's because we don't have talent for it.  Maybe it's because we hate doing it.  Maybe it's because we just don't know a few tricks of the trade. (Sadly, I find the that it’s missing the tricks of the trade, that holds us back the most … and learning the tricks, actually unleashes a passion in us, because we no longer suck at it … it’s such a chicken and an egg scenario time and time again.) Chances are you know somebody who is...(Read whole news on source site)

Building Single Page Apps with Knockout, jQuery, and Web API - Part 1 - The Story Begins

AddThis Social Bookmark Button
I’m currently recording a course for Pluralsight with a working title of “Building Single Page Apps (SPA) with ASP.NET Web API, Knockout and jQuery” targeting to be out by August 31. This is an end to end course that hits hundreds (ok, not quite) of technologies that work together to create a SPA that works across multiple devices and screen sizes. As I’m recording the videos, I thought it might be fun to occasionally blog about the experience as there were many good tips (and trips) I hit along the way. I really wanted to share an end to
end demo that doesn’t cover every feature of every technology, but rather how they all work together in symbiosis. So the first module starts out by talking about what is a SPA, why you should be interested even if you aren’t building a SPA, and what the story is for the end to end demo. Basically, it’s the lead in to the entire course. And thus, that’s where this post starts. One of the coolest parts of this course is the tremendous number of people who influenced it. The developer community we work in is amazing and I try not take you...(Read whole news on source site)

Building Single Page Apps with HTML5, Knockout, jQuery, and Web API - Part 3 - Server Technologies

AddThis Social Bookmark Button
Some skills never go out of fashion. Managing data and serving it up to a client is one of those skills. Sure, the technologies change and the way we use them, but we’re still gathering and delivering data. Recently I wrote about how my new course is progressing for Pluralsight. The course, titled “Building Single Page Apps (SPA) with HTML5, ASP.NET Web API, Knockout and jQuery” , is an end to end course. This means I cover the app and how it uses all of the technologies to produce the SPA. You can read the previous posts in this
series here: Part 1 - The Story Begins (What is the Code Camper SPA?) Part 2 - Client Technologies Today I’ll share some insights on the server technologies I am using in Code Camper SPA. The diagram below shows the key ingredients I used to create the server technologies. One of the goals of this architecture is to surface the data in an simple way so I can add new ways to get to the data or even add new data fairly quickly. The main idea was to keep the Web API’s methods simple, which...(Read whole news on source site)

How to enable Delete Confirmation Dialog in Windows 8?

AddThis Social Bookmark Button
I have been trying the Windows 8 Consumer Preview and here’s one thing that I noticed about the Confirmation Dialog. By default, the Windows 8 doesn’t ask you for the confirmation when deleting a file or a folder. So, when you press a delete key on selecting a file or a folder, the file/folder is deleted straight away and moved to the Recycle bin. If you want to enable the “Delete ConfirmationR Read More....

Few days I have written a blog post about Multiple file upload with asp.net 4.5 and Visual studio 2012. It was greatly appreciated by the community and also been part of www.asp.net community daily spot light.  On that post one of my reader Ciwan Kurd has requested the asp.net mvc version of that post. So in this post I will explain how we can do multiple file upload with HTML5. For this post I am going to use asp.net mvc 3 with HTML5 template and visual studio 2012
but you can use same techniques in any version of asp.net mvc.  First things we needs to do create a HTML form for the uploading file in asp.net mvc view so following is a code for that. @using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" })) { } In above code that I have use @HTML.BeginForm to create a HTML form with multipart as this attribute is required to upload any kind of files on the server.
