Nowadays, transacting business through E-commerce platform has become an important business trading way in modern society. E-commerce has been applied to literally every aspect of our society. The requirements of users are variable, different methods are in need of realizing E-commerce, even the deployment platforms are different. The JSP, ASP, HTML and other traditional scripting language has become unable to meet the needs of designing a complex system, even if it has been realized, the coupling between codes, the configuration environment and system deployment dependency fall far short of various requirements of users. It is a highly skilled work which demands good conception of beauty and much professional knowledge of the program designers. However, it is difficult to fulfill the needs in reality.

DOT NET is one of the key products that enable application development under the new vision. However, DOT NET is not quite backward compatible with prior versions like visual basic version 6. This makes migration a serious issue. Converting existing source code to DOT NET architecture is not just a matter of loading it to the new version. DOT NET has its built-in migration tool, which performs the vital task of converting the source code syntax. But that’s just half of the work done. But before the converted code is actually compiled, the developer needs to enable it to smoothly fix lot of issues to fit into DOT NET architecture. In present efforts to find out solutions to these migration issues, a re-engineering Migration Model for Legacy Source Code (MMLC) has been proposed in this study. Proposed model has been further validated using a in-house project at one of the leading software development organisation. It is envisaged from the experimental try-out that the model would help the developer community to easily convert their legacy source code to DOT NET framework.

A Word About Secure Database Access
Unfortunately, this database access code exhibits insecurities of its own. For example, you should never use the sa account (or an equivalent) to access databases from Web applications. Instead, use weak accounts that lack permission to drop tables, insert, update, and delete records, and the like. In addition, you should use stored procedures or parameterized commands in lieu of dynamic SQL commands for added protection against malicious input parameters. Finally, consider encrypting database connection strings to minimize the risk of information disclosure if your source code falls into the wrong hands. And note that truly paranoid ASP.NET programmers encrypt connection strings and store them in ACLed registry keys. When it comes to Web security, a little paranoia can be a good thing.

Information and communication technologies continue to pervade our lives in various aspects which include health, education, entertainment and ecommerce. People need to be able to trust computer systems as the dependence on them increases. The Trustworthy Computing vision (CRA, 2003) refers to computer systems that are intuitive, controllable, reliable and predictable and that ensure availability and security. Secure cod- ing is not trivial and poor code security management may leave the developed web application vulnerable to attack or turn the application into a launch pad for serious attacks.

All SimBLOX simulation products employ an agent-based or object-oriented architecture. This allows the user to create very large, complex, macro-level simulation models by connecting together many smaller, easily understandable, micro-level “building block” models. In this simple tutorial, we will show you how to use the Water Resource Planning SimBRIX.

Test-driven development is something that every developer can appreciate once they?ve tried it, and something that I?ve worked hard to enable for Silverlight with the release of the controls source. Scott Guthrie previously posted about the Silverlight 2 Beta 1 release, with a First Look at Silverlight 2 post followed by the First Look at Using Expression Blend with Silverlight 2. If we could take the same application from the Blend post & create a set of unit tests for the components in the app, it would pay dividends once we start adding new features or working with other developers on the project.

As the desire to deliver rich web content and functionality has increased over the last decade, Rich Internet Application (RIA) technologies have become increasingly powerful. Unfortunately, many of these technologies have been out of reach for many client application developers because of the non-trivial learning curve involved. In addition, with the number of RIA technologies available, where do you even begin? In many cases, there was not a “one size fits all” solution, so RIA development would involve a mix of HTML, JavaScript, Adobe Flash, and perhaps a little AJAX thrown in (just to name a few possibilities).

Windows Presentation Foundation (WPF)
WPF provides a unified framework for building applications with rich user interfaces and interactivity. It is built on top of the .Net Framework and makes use of the managed and unmanaged code. WPF programming model allows the developers to write code once and deploy it as a standalone installed application or in a browser.
