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.

With Active Directory, Microsoft has provided administrators with a powerful directory service to organize network data and to control access to network resources from a central point. However, “powerful” by necessity also means complex, and the complexity of Active Directory has probably contributed to slowing down the rollout of Windows 2000 and 2003 servers. Initially, many organizations found simply migrating their flat NT4 domain structures into a more sophisticated Active Directory wrapping to be a significant challenge. By now, many have defined their Active Directory Forests, survived an often cumbersome deployment process, and seen their directories mature into efficient tools for centralized administration. Policies have become the levers of network management, and, as a result, Active Directory has become a repository holding extremely sensitive data.

If you work with Microsoft technologies, most likely a portion of your development effort is taking place within Visual Studio, Microsoft’s flagship developer environment. Microsoft products such as SharePoint, Commerce Server, Exchange Server, BizTalk Server, Office, SQL Server, CRM, Windows Mobile Devices, and even the Xbox all support .NET development, and most have deep integration with Visual Studio.

With the release of Visual Studio 2008, Microsoft has further enhanced the environment, and added support for new features. We’ll take a look at these enhancements, broken down into four groups: Environment, Designers, Language, and Products.

The Insider’s Guide to Windows Vista ARTICLE DATE: 12.20.06 By John Clyman Windows Vista is here at last. One of the largest software projects ever undertaken, Vista is indisputably a milestone—despite Microsoft’s having abandoned many of its most ambitious goals for the OS and not just for Microsoft but for the entire PC industry. Of course, Vista is not without its skeptics. PC makers say it will require more processing power, graphics capabilities, and memory than is typical of today’s mainstream machines. Software vendors complain that Vista’s vaunted security features are, in fact, locking them out.
