Have you ever come up with an idea and you think “Wow.. this is either brilliant or a total hack that no one under any circumstances should consider!"? That’s the situation I find myself in today. I either did something so monumentally stupid that Eric Shupps and Andrew Connell would love nothing more than slap me upside the head (which they probably want to do anyway) or it wasn’t totally stupid and you’ll think “Hey… that’s not a bad idea.”. So… which is it? Well… allow me to explain the situation ...
This is the second in a series on architecting software solutions where I discuss items that need to be discussed, addressed, resolved, etc. prior to finalizing any system designs.. Part I of this series “Know Your Audience” can be found here. One of the easiest pits to fall in when architecting software solutions is to attempt to design the solution to be all things to all people. Unless the application is incredibly simple and/or has a very narrow use, it is possible to spend substantially more ...
Quick Link: download ASP.NET MVC Preview 1 It is a an exciting time to be a web developer. There are lots of new technologies from Microsoft coming out for the browser (IE9 changes everything), in the area of tooling (the brand new WebMatrix) and for the server – with ASP.NET MVC 3 Preview 1 released today (27th July 2010). Download and install side by side with MVC 2 If you have Visual Studio 2010 (The FREE Web Developer edition is fine) then you can safely download ASP.NET MVC Preview 1 (download ...

"VWG was designed to solve what might be the most painful issues for enterprise IT; reproducing client/server richness and user experience on Web and Cloud, in a simple cost effective way and with standard Web, no-plug-in accessibility and absolutely secured ...
First of all, sorry for not posting for a quite long time. I have started working on designing and developing a charity website for blood donation. So all my leisure time was diverted into that. I will ensure that going forward, I post at least one post every week. Lets get into the topic of this week, without delaying any more time. I have always been using asp:Menu and asp:Treeview for transforming the sitemaps to super cool menu which are auto generated by ASP.NET for us. But I wanted more and ...
Most simple forms we write, especially in LOB applications, are repetitive sections of inputs and/or displays. Take a look at an exmaple from the MVC Music Store sample, the album editor template, notice anything repetitive? <%@ Import Namespace="MvcMusicStore"%> <%@ Control Language="C#" Inherits="System.Web.Mvc.Vi... %> <script src="/Scripts/MicrosoftAjax... type="text/javascript">&... <script src="/Scripts/MicrosoftMvcA... ...
http://www.microsofttransla... tool from Microsoft allows you to convert the language of your content on the fly. It is very intutive, effective and can be used for various locale generation requirements. It emits the below given <div> with the javascript:- <div id="MicrosoftTranslatorWidget" style="width: 200px; min-height: 83px; border-color: #3A5770; background-color: #78ADD0;"><noscript&g... href="http://www.microsoftt... ...
Two posts ago, I talked about the C# enum and some of its pitfalls (here). This post continues with a discussion of the fundamentals of enums by continuing with using enums and bit-flags. Defining a [Flags] Enum Now, we’ve seen previously that enums are typically used when you want to represent a type that can be one of a distinct set of values. But they can also be used to store a combination of discrete values. That is, the standard use of an enumeration is to support mutex options - such as an ...
Recruitment and interview process usually becomes complicated and very hard to follow with massive exchange of emails, bulky attachments and several people involved. So it was decided to develop a system that would simplify that process by allowing to find required information at a touch of a key - a web-based workflow-based application to automate the process without any need to install software on the client. The solution also needed to provide automated workflow to route tasks to the relevant ...
An article was published at JupiterJS.com (titled “JavaScript vs Silverlight”) arguing that JavaScript is better than Silverlight. Unfortunately, there is no way to post comments on that page (weird, really) so I decided I would post my answer here. First let me state that I do not think that Silverlight is an opponent, nor a threat to JavaScript. I love both, I write both, and both are helping me to create better experiences. Also, Silverlight has grown to be much more than “just” a web plug-in. ...
In my last fundamentals post, Chuck had requested an example of how to translate between enum and int without resorting to casting or other hard-coded mechanisms that depend on the actual values of the enum. One of the problems, of course, with casting between enum and int (for example to represent the enum as an int in database) is that it is a very tightly-coupled bond. Any changes to the underlying data or to the enum could have disastrous consequences. Thus, it is often more desirable to have ...
If you are working with iframe in which the content takes time to load, you may want to display a simple loading indicator to the end users instead of letting the users see a blank screen in the page. To do this, here's one way on how to implemet it using javascript. <html xmlns="http://www.w3.org/19... > <head runat="server"> <title></title> <script type="text/javascript"> function hideLoading() { document.getElementById('di... = "none"; document.getElementById('di... ...
Technorati Tags: jQuery,JavaScript I'm using the jQuery UI Autocomplete plug-in on my current intranet project, and am impressed with how powerful and easy to use it is. It works great on my development PC with Internet Explorer 8, and I was very pleased with myself. …until I tested on one of our "thin client" machines, and my beautiful autocomplete dropdown looked like Swiss cheese: The browser on the thin-client is, you guessed it - everybody's favorite browser - IE6. IE6 has z-index issues that ...
This week, Scott Guthrie, Corporate Vice President at Microsoft’s Developer Division, announced, via blog post, the early Beta release of a new tool called WebMatrix. WebMatrix is a free developer tool that enables Web development geared toward what might I might call Markup-and-Script developers (more on that in a minute). And although WebMatrix draws upon technologies already, or soon to be, present in the fuller ASP.NET Web development platform and the Visual Studio integrated development environment ...
Here is the function function getQuerystring(key, default_) { if (default_ == null) default_ = ""; key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"); var qs = regex.exec(window.location.... if (qs == null) return default_; else return qs[1]; } *taken from http://www.bloggingdevelope... ...
Continuing on the same vein as my last topic where I discussed differences between C# const and readonly keywords (here) and their uses, today I’m going to look at C# enums and their pitfalls. I will only be discussing the basic enums today (the post got kind of long so I’ll discuss enums marked with the [Flags] attribute next post). Quick Recap of Enums First, a quick recap of enums for those who are brand new or less familiar with them. Basically, enums a great way to declare a variable of a type ...
I've spent the last few weeks trying to comprehend OOP and inheritance in JavaScript. After that amount of time I've come to the conclusion that harly anyone really understands it and everyone implements it a different way. Just look at this question someone posted about the best library to use for JS inheritance. I thought it was funny because although there were a lot of answers, I think everyone proved his point, that there are many of them and no one could agree on the best. stackoverflow.com/questions... ...
First of all, I must apologize for letting my blog go fallow… pretty good use of ‘fallow’ though, right? I mean how often do you get to throw that word around? I guess playing ‘Farmville’ wasn’t a total waste of time! Anyway, I’ve been up to my elbows in projects and family time and have just not had a chance to blog lately. So… where to start… oh yeah… Stop copying files directly to the 12 hive! Seriously.. I don’t care what the file is… custom controls? java script files? images? web parts? If ...
I was recently tasked with coming up with a way to keep the session alive in ASP.NET as long as the user had the web page open. That way if they started filling out a form, then went to lunch and came back, they wouldn't lose all of the information just because their session timed out. The concept is actually pretty simple. You just need to make a call back to the server every once in a while before the session expires to update the session timeout. We figured as long as the user has the browser ...
When MVC 2 was released, there was a last minute change to use Model Validation instead of Input Validation. Essentially, Model validation means that your entire view model will be validated regardless of which values actually got posted to the server. On the other hand, with Input validation, only the values that get posted to the server will get validated. While this was the right decision by the MVC team for the most mainstream cases, there are still some cases where the previous behavior of Input ...
Technorati Tags: JavaScript Did you know that there are two equality operators in JavaScript? The one that's used most often is the double equal sign ("==") operator. The "==" operator does type coercion. The following example returns true, even though we're comparing a string and a number: if ('5' == 5) That's not too bad, but you probably wouldn't expect the following examples to return true: if (0 == '') if (0 == false) if (false == undefined) if ("\r\n" == 0) They all do though, thanks to JavaScript's ...
Once again we delve into the world of C# Fundamentals. Those hints and gotchas that tend to bite folks newer to the language. Today I take another look about the differences between const and readonly and the uses for each. For the purposes of this entry, whenever I say constant i mean a const or readonly. Const – Compile-Time Constant Values First of all, for those of you who came from the C++ and C# world, const in C# is not the same as const in that language. A const in C# can be closest considered ...
I was playing around with ASPNET AJAX MaskEditExtender control and ASPNET Validation controls when I was working with a profile page and doing some input validations. Everything seems to be fine until I was told to always retain the phone mask format in the TextBox. Here’s my code for Phone number masking: <asp:TextBox ID="TXTPhoneNumber" runat="server" MaxLength="13" ValidationGroup="GroupA" /> <asp:MaskedEditExtender ID="MaskedEditExtender1" runat="server" TargetControlID="TXTPhoneNu... ...
Technorati Tags: jQuery,JavaScript I'm sure I've "invented" a technique that's been done by many others (and I don't doubt that there's a slicker way to do it), but… Sometimes I'll want to have an identical chunk of HTML repeated more than once on a web page, for example: a search page with "Search" and "Clear Fields" buttons both above and below the search field inputs. I'd like to just render that HTML once on the server, than "clone" it on the client. For my site, I established a convention where ...
C# Fundamentals Genesis I’ve decided to begin a line of back-to-basics blogs that I hope to post regularly. I used to teach C++ Programming, Algorithms, and Data Structures courses at Webster University in the evenings here locally, and have missed those teaching and mentoring moments when I had to stop teaching after the birth of my twins (no more free time for me!). While some of these fundamentals will be obvious to those who know the languages well (I hope to post C# and C++ tidbits), I’m hoping ...
June 21st, 2010 The Importance of Open Government Data To all those present, good afternoon. My name is Andrew Brust. I help run a consulting firm, twentysix New York, here in Manhattan. I am also a technology columnist and blogger, and serve on the New York Technology Council’s Advisory Board. As I have explained in previous testimony, I am a lifelong New Yorker, and began my IT career in the employ of the government of the City of New York. I’ve testified to this Committee before, voicing my support ...
Many times in the Career advice section at http://www.dotnetfunda.com/... we are asked this question What are the essential skills for a web developer? Rather than posting/reposting time and again, thought of writing a post about it. This post details what according to me and some of the well established people I know think about essential skills that a web developer should posses. You can find similar entry at Essential Skills for Web Developer in 2010 HTTP/TCP protocol from a very high overview ...
Technorati Tags: .NET,Kansas City Thanks to the KC development community for a great free event. The Johnson County Community College provided very nice facilities. I’m the sort of guy who would willingly drive 4+ hours each way for a free XL (or “developer medium”, as Richard Campbell calls it) T-shirt, but got a lot more than that out of the event. Here's a recap of the sessions I attended: Why Kanban? speaker: Troy Tuttle Troy is a “pragmatic agilist” at AdventureTech (not AdventureWorks – I was ...
I have just tried the Solar Winds IP address tracker. One comment about their download process - it does require JavaScript enabled for their site. It detected the machines on my LAN. Here is the marketing blurb from their web site. FREE IP Address Tracker scans, tracks, and consolidates your IP address information in one easy place, saving you time, eliminating errors, spreadsheets and headaches! Its simple-to-use features allow you to: Track IP addresses for a unified, at-a-glance view of your ...
When Microsoft rolled out Visual Studio 2010 with C# 4, I was very excited to learn how I could apply all the new features and enhancements to help make me and my team more productive developers. Default parameters have been around forever in C++, and were intentionally omitted in Java in favor of using overloading to satisfy that need as it was though that having too many default parameters could introduce code safety issues. To some extent I can understand that move, as I’ve been bitten by default ...

Smooth Streaming provides a high-quality viewing experience that scales massively on content distribution networks, making true HD 1080p media experiences a reality. The player integrates leading social networks such as Microsoft Live Messenger, Twitter ...
After more time than I care to admit I have finally released a rudimentary Http Handler for serving compiled CoffeeScript from Asp.Net applications. It was a long and painful road but I am glad to finally have a usable strategy for client-side scripting in CoffeeScript. Why CoffeeScript? As Douglas Crockford discussed in detail, Javascript is a mixture of good and bad features. The genius of CoffeeScript is to treat javascript in the browser as a virtual machine. By compiling to javascript CoffeeScript ...
While ASP.NET provides an event base approach it is completely dismissed when working with AJAX and the richness of the server is lost and replaced with JavaScript programming and couple with a very high security risk. Visual WebGui reinstates the power of the server to AJAX development and provides a statefull yet scalable, server centric architecture that provides the benefits and user productivity of AJAX with the security and developer productivity we had before AJAX stormed into our lives. "When ...
Update: I revised some of my initial thoughts after taking bit of my own advice and thinking about the less-tangible benefits of a ConcurrentDictionary. This leads me to believe that ay time you use a Dictionary in a read/write manner in a multi-threaded environment, you should use ConcurrentDictionary instead for the simplicity and safety. It's easier to read and more maintainable, and even if you are write-heavy, it's not orders-of-magnitude slower so I think it's worth it for the safety and maintainability ...
I am working on a Javascript app (CloudGraph) that uses HTML5 canvas and JQuery. I'm using ExplorerCanvas to support canvas in IE. I recently came across an interesting problem. What I was trying to do is restore the user's settings when the page is loaded by reading some information from a cookie that I set the last time the user accessed the application. One of these settings is the size of the canvas. I decided that the best place to do this would be when the document is ready using JQuery $(document).ready(). ...
Technorati Tags: ASP.NET,ASP.NET MVC,T4MVC I’m working on my first ASP.NET MVC project, and I really, really like MVC. I hate all of the “magic strings”, though: <div id="logindisplay"> <% Html.RenderPartial("LogOnUs... %> </div> <div id="menucontainer"> <ul id="menu"> <li><%=Html.Action...

I recently was given an assignment to create a UX where a user could use the up and down arrow keys, as well as the tab and enter keys to move through a Silverlight datagrid that is going be used as part of a high throughput data entry UI. And to be honest, I’ve not trapped key codes since I coded JavaScript a few years ago. Although the frameworks I’m using made it easy, it wasn’t without some trial and error. The other thing that bothered me was that the customer tossed this into the use case as ...
I was working on my online mathematical graphing application, CloudGraph, and trying to make it work in IE. The app uses the HTML5 canvas element to draw graphs. Since IE doesn't support canvas yet I use ExplorerCanvas to provide that support for IE. However, it seems that when using excanvas, if you try to moveTo or drawTo a point that is not finite it loses it's mind and stops drawing anything else after that. I had no such problems in Firefox or Chrome so it took me awhile to figure out what was ...
The opinions mentioned herein are solely mine and do not reflect those of my employer Wanted to post this for a long time but couldn’t. I have been an ASP.NET Developer for quite sometime and have worked with version 1.1, 2.0, 3.5 as well as the latest 4.0. With ASP.NET 2.0 and Visual Studio 2005, came the era of AJAX and rich UI style web applications. So, ASP.NET AJAX (codenamed “ATLAS”) was released almost an year later. This was called as ASP.NET 2.0 AJAX Extensions. This release was supported ...

Technorati Tags: .NET,WatiN,testing In addition to my automated unit, system and integration tests for ASP.NET projects, I like to give my customers something pretty that they can look at and visually see that the web site is behaving properly. I use the Gallio test runner to produce a pretty HTML report, and WatiN (Web Application Testing In .NET) to test the UI and create screenshots. I have a couple of issues with WatiN’s “CaptureWebPageToFile” method, though: It blew up the first (and only) time ...
Looks and design is becoming more and more important for customers and organizations event when we deal with internal enterprise applications. However, many web developers who work on business apps end up not investing resources on the design. The reason may be that they ran out of time so with their client's pressure there was no choice but to skip past the design process. In some cases, especially in sall software houses, there are no trained professional designers and the developers have to do ...

Unfortunately HTMLEditor component of AJAX Control Toolkit is not compatible with the UpdatePanel. The problem is when we use accents with the Mozilla Firefox browser and HTMLEditor is inside an UpdatePanel. Letters that contain accents are left with an unknown character (so is stored in the database or even returned a PostBack). Can be tested using Mozilla Firefox on the site of the ASP.NET AJAX Control Toolkit. Write a word with accents and go to "Submit Content": http://www.asp.net/AJAX/Aja... ...
A few weeks ago I did the following post asking people – if they used foreign key constraints in their star schemas. The poll is still open if you are interested in adding to it, but here is what the chart looks like as of today. (at the bottom of the poll itself there is a link to the live results, unfortunately I cannot link the live results in here as the blogging platform blocks the required javascript) Interestingly the results are fairly even. Of the 78 respondents, fractionally over half at ...
A few days ago Stacy Draper and I were chatting about what it means to be a SharePoint Developer. That actually turns about to be a conversation with lots of shades of grey. Stacy thought it would make a good blog post… well, I can’t promise this to be a GOOD blog post… So, anyway, I decided to let off a little bomb this morning by posting the following tweet on Twitter: @mrackley: Can someone be considered a SharePoint Developer if all they know how to do is work in SPD? Now, I knew this is a debate ...
The competition between the Web and proprietary rich platforms, including Windows, Mac OS, iPhone/iPad, Adobe’s Flash/AIR and Microsoft’s Silverlight, is not new. But with the emergence of HTML 5 and imminent support for it in the next release of the major Web browsers, the battle is heating up. And with the announcements made Wednesday at Google's I/O conference, it's getting kicked up yet another notch. The impact of this platform battle on companies in the media and advertising world, and the ...
So we've all coded a Singleton at one time or another. It's a really simple pattern and can be a slightly more elegant alternative to global variables. Make no mistake, Singletons can be abused and are often over-used -- but occasionally you find a Singleton is the most elegant solution. For those of you not familiar with a Singleton, the basic Design Pattern is that a Singleton class is one where there is only ever one instance of the class created. This means that constructors must be private to ...
Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan. Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn. How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that. NBC’s Studio 8H, where the Office launch was held yesterday (and from ...
Mostly all who works extensively on SharePoint (including meJ) don’t like to use out-of-box list forms (DispForm.aspx, EditForm.aspx, NewForm.aspx) as interface. Actually these OOB list forms bind hands of developers for the customization. It gives headache to developers to add just one post back event, for a dropdown field and to populate other fields in NewForm.aspx or EditForm.aspx. On top of that clients always ask such stuff. So here I am going to give you guys a flight for SharePoint Customization ...
