Database local cache
You are developing a desktop application for managing a fitness center. The members information is of course to be stored in a database, so you define a "Members" table with fields such as name, birth date, telephone, and the like. But your happiness ends when you are faced with the requirement of recording the member's photo together with the rest of the data. Then the second most trascendental question in human history (right after the meaning of life) comes to your mind: Should I store the photo in the database for the sake of data consistency, or in the local filesystem for the sake of performance?

A New Task Scheduler Class Library for .NET
Task Scheduler is the Windows service that schedules and automatically starts programs. Windows Explorer presents a user interface to the service when you browse the %WINDIR%\TASKS folder, typically from the shortcut in the control panel. From the command line, the
schtaskscommand and the oldatcommand do the same. Programmers have a well-documented COM interface, but the .NET framework does not offer any wrapper for it. The present library provides that .NET wrapper. -

Dissecting ASP.NET Version 3.5's Web.config File
In November, Microsoft released the final version of ASP.NET 3.5 and Visual Studio 2008. As discussed in An Overview of ASP.NET 3.5 and Visual Studio 2008, version 3.5 is not a major reworking of the .NET Framework. Rather, it adds new classes and functionality on top of the existing core.

Creating a Data Access Layer for Paging in SQL Server 2005
Visual Studio 2005 introduced a number of tools that allow web developers to create dynamic web pages more easily than ever. The GridView encapsulates most of the functionality needed for displaying and editing tabular data efficiently, and can bind to several types of data sources. The DetailsView is a sibling to the GridView, supporting most of the same functionality but displaying a single record at a time. While these controls can bind to databases through simple DataSets and SqlDataSources, the ObjectDataSource control provides a more clearly defined, more sophisticated -- but potentially more complicated -- connection. For developers looking to model their SQL data within the application through custom classes, the ObjectDataSource allows them to bind their strongly-typed classes to user controls and add a discrete Business Logic Layer to ensure user interactions follow defined rules of behavior.

MyFriends : A simple contact keeper using XLINQ/LINQ/WPF
The other week I was surfing the web and I came across something that perked my interest, and this article is kind of a result of what I found. Basically, I come from a database type of background, so am used to seeing forms with grids, list and listviews which were functional, but looked pretty boring. This is kind of why I like WPF so much, as you can make functional apps, but make them look really sexy. Anyone that has done any WPF will probably know, that there are a couple of data type controls, such a
ListBoxand aListView, and with some clever binding and some templating/styling we could probably make these look like a grid. But the truth is that there simply is noDataGridor anything like that. -

Understanding Code Access Security in .NET
In Microsoft .NET you have two types of security, Code Access Security and Role Based Security. In this article we will explore what the latter implies, how it can be used, etc. So, what is Code Access Security then? Code Access Security (CAS) is a security feature of .NET that enables the code that is to be executed to be properly verified and different levels of trust granted accordingly. It actually provides the flexibility to define what the code could perform and what not to perform. This article discusses CAS, the functions and benefits of CAS, permissions and permission sets.

Creating and Consuming ASP.NET AJAX Page Methods
Web services provide a great way to exchange data between ASP.NET AJAX pages and a server using lightweight JSON messages (see my previous articles for examples of integrating Web services into ASP.NET AJAX applications). However, creating a separate .ASMX Web service file and adding the ScriptService attribute to the service class may feel like overkill in situations where a single page consumes the service's methods. In some cases, it's more convenient to simply add the functionality provided by the Web service directly into an ASP.NET code-beside page. In these cases, ASP.NET AJAX page methods can be used instead of Web Services.

Authenticating Users with ASP.NET AJAX
However, each time a user logs in to your application, a postback operation occurs which, in some situations, may not be desirable. In cases where you'd like to log users into a Web site without performing a complete postback of a page, you can use the ASP.NET AJAX authentication service instead.

DataTableReader in ADO.NET 2.0
In this fast and furious world, everyone needs everything to be faster. Once upon a time Pentium MMX was considered as faster system, but now we don’t accept even Pentium Dual core as the fastest system. If this is the situation for a computer system, then what will be the situation for the data we managed in our web application? Readers need data to be load faster into their webpage irrespective of the size of data that page contains. So someone in someway needs a solution to overcome this problem. Let us go straight to the concept.

Creating Globally Unique Identifiers (GUIDs)
When storing data, either in a database or other storage medium, it is usual to assign an identifying value or key against each item held. There are many ways in which to generate such a key. In an accounting system, the ID for each customer may be entered by the user or generated from other data using a standard that is easy to remember. In this case, the software will perform a validation check to ensure no duplication. In other systems a sequential series of numbers may be used to ensure that the keys remain unique.

Fast Exporting from DataSet to Excel
Exporting data from a .NET application to Excel is a very common requirement. A simple search on the Web results in several examples that show us the method to copy data and put it into the Excel cells. However, there is a payload with this method: each interaction to put a value into an Excel cell requires an InterOp invocation. If the amount of data to transfer is huge, we have a problem with the performance of the method. Is there a better way to accomplish this?

Basic of GDI+
In this article, Handy Chang will explain about GDI+ in .NET Framework. If you haven't heard about GDI+, then GDI+ is a set of classes in .NET framework that deal with graphics. You can use GDI+ to draw custom drawing on the screen. GDI provides a layer of abstraction, hiding the differences between different video cards.
You simply need to call the Windows API function to do the specific task, and internally the GDI figures out how to get to the client's particular video card to do whatever that you want.
Although GDI exposes a relatively high level API to developers, it is still an API that based on the old Windows API with C style functions. GDI+ sits as a layer between GDI and your application providing more intuitive and inheritance based object model.
GDI+ is generally considered a Windows technology. However, some of the new GDI+ features make this technology an excellent choice for Web applications, enabling developers to generate images, graphs, diagrams, and much more. -

Developing a Wiki with ASP.NET
Recently, more and more articles and books have been published on the ASP.NET AJAX framework 1.0 ("MS AJAX" for short).

Can the alt attribute be omitted without hurting accessibility?
In the current editor's draft of HTML 5, it is suggested that the
altattribute forimgelements should no longer be required. The reasoning is that in some cases alt text will be omitted, regardless of whether it is required or not, so it might as well be made optional. Otherwise some authoring tools will automatically insert empty, repeated or meaningless alt text. At least that's how I understand the reasoning explained in Why the Alt Attribute May Be Omitted. -

Monitor your clipboard
Clipboard Text Scrubber is a handy little application that sits in your system tray and monitors your clipboard. When it finds any text on the clipboard it will “scrub” (or “clean”) that text, to remove all formatting. This is great for copying and pasting text into emails, documents or anywhere else. You can also (optionally) remove all HTML tags from the clipboard text, which is excellent for copying and pasting things from the web, without getting all the extra markup. Anyone that uses notepad to scrub their text will love this application. You can have Clipboard Text Scrubber automatically scrub text as it detects it, or you can manually scrub it by right-clicking on the system tray icon. When Clipboard Text Scrubber is scrubbing text the system tray icon will change, just to let you know it’s hard at work.

Creating tabbed dialogs using AJAX
Tabbed dialogs come handy when you have too many controls on your web form. If all the controls are placed at once in front of the user the page may look cluttered. Instead you can logically group the controls using a tabbed user interface making it neat and easy to use. One way to develop such a tabbed user interface is to use MultiView and View server controls. However, being server controls these controls require a post back while switching between the tabs. ASP.NET AJAX and HTML tags can be put to use in developing a client side tabbed dialog. This article is going to show you just that.

Creating an AJAX Rating Widget
Frequent visitors of ajax enabled websites, like ajaxian, have all witnessed them already: ajax rating widgets. They are flashy, animated, you can use them to rate the content (usually without refreshing the page) and if you could, you'd present them to your parents and marry them. Compared to the classic rating system, as on IMDb, they incite people to click them, reducing the effective rating process to only one click.

Edit and Encrypt Web.Config sections using C# 2.0
ASP.NET 1.x allowed configurations in web.config file to be read from .NET application. But there were no options to manipulate Web.Config contents in programatically. To achieve this we had to consider Web.Config file as a normal file or an xml file. .NET 2.0 fills this gap and also provides many other useful operations to be carried out on Web.Config file; like editing and encrypting sections of Web.Config file. This articles illustrates these functionalities via a sample ASP.NET application.

Some ASP.NET 2.0 Configuration Tips
It is a common scenario for ASP.NET Web developers to want to have different sets of configuration data depending on whether the project is being developed locally within Visual Studio in Debug mode, being tested in QA in Release mode, or is in Release mode in production. Also, settings may differ from machine to machine if the Application is deployed into a web farm scenario.

Distributed Transactions in .NET 2.0
Transactions are commonly used to update data as a batch. If any one operation from the batch is failed the entire batch of operations must be cancelled. Thus either all operations in the batch succeed or all of them are cancelled. ADO.NET 1.x provided SqlTransaction class that in conjunction with SqlConnection class provided to commit or rollback transactions. In .NET 2.0 an additional technique can be used and that is what is the topic of this article.

How to create ProgressBar user control
In any user centric application, we always strive to make application more interactive and user friendly. When ever user performs any heavy or lengthy operation (Uploading/downloading a large file or Installation) he or she expects to know the progress of operation at regular intervals. The user should be made aware of status whether it may be success or failure at each step. We cannot keep user waiting. The user should be informed of percentage of task completed.

Inserting Images into Database and Display it in GridView through Handler.ashx
Introduction This article explicate the method of inserting images and pictures into SQL Server database table and display it in an Asp.Net GridView control with the help of Handler.aspx. Description Have you seen any web application or website without images? No, you cannot. Images played a major role in web application development. Either it’s a static html website or an advanced RAD application, everything is build along with images. If your application is an E-Commerce based or Image Gallery portal, definitely you have to suffer lot on saving the images in different location with different sizes and types. And it’s not an easiest job to manage those unwanted and outdated images to be removed from your file server, then making backup of those images from one server location to another location. So it is clearly time consuming and hectic. -

Building a User Control that displays RSS feeds
Introduction
Displaying data in ASP.NET verison 1.x required writing code to programmatically retrieve the data and then more code to bind the data to a data Web control, such as the DataGrid. ASP.NET 2.0 simplifies the process of working with data through its data source controls, which allow data to be retrieved and even modified through declarative means. In short, ASP.NET 2.0's data source controls permit developers to work with and display data without having to write a line of code. For a more thorough look at working with data in ASP.NET 2.0, be sure to check out my Accessing and Updating Data in ASP.NET 2.0 article series.Different data source controls are designed to work with different types of data. The XmlDataSource control, as its name implies, is designed for working with XML data. By setting a few properties, it is possible to retrieve XML data from a remote URL or local file, transform it using XSLT, and filter it using an XPath expression, all without writing a line of code. This data can then be displayed by binding it to a data Web control and XPath databinding statements can be used to bind specific chunks of the resulting XML to other Web controls.
In this article we will see just how easy it is to display XML data in an ASP.NET 2.0 page. In particular, we will build a User Control that will display the contents of an RSS feed. Once created, this User Control can be dragged onto the Design surface of any ASP.NET page in your project and configured to display the contents of a particular RSS feed by simply setting the control's
Urlproperty to the URL of the RSS feed. -

Working with Transactions
A transaction is a group of operations combined into a logical unit of work that is either guaranteed to be executed as a whole or rolled back. Transactions help the database in satisfying all the ACID (Atomic, Consistent, Isolated, and Durable). Transaction processing is an indispensible part of ADO.NET. It guarantees that a block of statements will either be executed in its entirety or rolled back,( i.e., none of the statements will be executed). Transaction processing has improved a lot in ADO.NET 2.0. This article discusses how we can work with transactions in both ADO.NET 1.1 and 2.0 versions.

Refresh module
Most of you are familiar with the feature of all web-browsers that when you press the F5 button, the content of a page is refreshed. After the F5 button is pressed, the browser repeats the previous request to the page. Nothing wrong will actually happen when the previous request is made by the GET method. However, problems appear when the last request is made by the POST method. Let's consider an example where a user is transferring money to a shop to pay for some goods. Having completed this operation, the user refreshes the page and as a result the server code is executed once again with the same data. Thus, the user may accidentally pay twice.

Role of HTTP Modules in .NET Security
Today, one of the important goals is to provide high security to the distributed Web Applications. The security is designed throughout the .NET Framework like Code Access Security, ASP.NET Integrated Security and Cryptography, which can be optimally used to develop Secure Applications.
However, in scenarios where one has to perform Authentication or Authorization by the database and give appropriate privileges to the users (or) the permissions have to be provided at the runtime for specific operations (or) in scenarios like where no web browsers are used , it becomes crucial to develop Custom Security.
The ASP.NET Framework has defined set of Http Modules which takes care of the basic Authentication and Authorization mechanisms. The Custom Security (Custom Authentication or Authorization) can be performed in Forms Authentication or Windows Authentication by coding in the Global.asax file, which is not a reliable (or) reusable solution. The .NET Framework gives the flexibility to develop custom Http Modules and plug them into the ASP.NET Application,hence enabling to develop highly scalable, reusable and reliable .NET Security Components.
This article explains in detail about the HTTP Modules and the steps to create custom Http Module with an example. The article also gives a brief how to create a custom Http Module in developing a custom database authorization module. -

Get All URLs on a Page
In this article, I show a class that can be used to find and display all of the urls on a web page. What for you may ask? Well, in my experience as a web developer, I have found a class like this to be very useful. Sometimes, you may want to use this class a a basis for a more complex application that crawls your site checking for bad or broken links. In other cases, you may simply want to check an individual page to make sure your links are formatted correctly, or don't contain any obsolete pages. You could also easily change this class to look for other items within your page, like specific text or tags. Who knows, this may be the start of a specialized spider that crawls sites on the internet looking for something specific.

There is an impedance mismatch between objects and normalized relational databases. Everyone knows this. Almost everyone has tried to fix it—think object-oriented databases—and some people have gotten famous off of proposed solutions. (Deservedly so or not.)

The issue phrased using my words is getting data from databases into objects makes for better programming but is time consuming, tedious, and not altogether convenient. From what I know of LINQ, LINQ for Data, and the Entity Framework, they may really be on to something.

This article approaches JavaScript from the perspective of an ASP.NET developer who is comfortable with the paradigms and patterns of either C# or Visual Basic.

The article assumes you already know that JavaScript is a loosely-typed language (because you don't have to declare the type of data you store in a variable), and that the syntax is similar to the C family of languages (with charming curly braces and stunningly beautiful semi-colons).

Filtering Custom Paged Results
Introduction
The ASP.NET 2.0 data web controls - the GridView, DetailsView, and FormView - all provide built-in paging support that can be enabled at the tick of a checkbox. Unfortunately, this built-in paging support is very inefficient when paging through large amounts of data since it naively grabs all of the records from the data being paged through even though only a subset of the records are displayed. Consequently, when paging through several hundred or thousands of records, it behooves you to implement custom paging. With custom paging, the data Web control hands over its paging responsibilities to us, the page developer. We are tasked with efficiently grabbing the precise subset of records to display and providing this information to the data Web control. -

Jump start Windows Workflow Foundation
Once a veteran programmer was asked to define his professional developer's career in as few words as possible. His answer was "passion", "excitement" and "learning". And that's absolutely true as new, bleeding edge, exciting technologies/frameworks/languages keep flooding the technology limelight; we programmers fuel our passion of we-can-do-anything by mastering them. One of the newest buzz phrases in the industry is "Windows Workflow Foundation" (WF). This article is aimed at getting a jump start into it to fuel excitement and pump up passion. Basic knowledge of .NET Framework is the only prerequisite for marching on with this jump-start tutorial. Examples are in C#, but VB.NET lovers are also invited to the show as this is all about framework, and if they can understand the pseudo code, programming it in VB.NET must be trivial.
