Introduction Most existing applications operate with data that must be stored and loaded in different times and different locations. The data is stored in text or binary files with a well defined format. The Problem Initially, in the first version 1.0, an application operates with data structures that can be stored and loaded. But, next […]

Introduction Due to its peculiar design and semantics, the standard smart pointer class auto_ptr was incompatible with other Standard Library components and was eventually deprecated. Shared_ptr was added to C++ programming in 2003 and has since replaced auto_ptr as the default smart pointer. However, it incurs noticeable performance overhead both in terms of size and […]

Introduction As stated in my previous article titled “Enhancing Windows Presentation Foundation (WPF) XamDataGrid from Infragistics“, Infragistics, one of the leading third-party control providers for the .NET framework has sufficient controls that adhere to my common tasks. Extension methods make C# programming code readable and developer-friendly. UI components generally tend to expose events and common […]

In part 1 we understood what a context menu was and how Visual studio helps to create one at the design time and runtime level on a windows form. In this tutorial we are going touch base on some of the key aspects of Context Menu controlled and generated by the shell explorer with the […]

Introduction Read along as we walk through the Slide Show extender control which is an important control in the Ajax control kit family by creating a small sample. This is an Ajax extender for an image control which will use the image control for performing the slide show. It is also possible to implement slide […]

One of the new ASP.NET controls available with ASP.NET 4 is the QueryExtender control. The QueryExtender is designed to simplify filtering data returned from a LinqDataSource or EntityDataSource by decoupling the filtering logic from the data source control. Using the QueryExtender is easy–simply add a QueryExtender to the page, specify what data source control it […]

A glance of C++0x std::thread False Sharing and Benchmark Some other thoughts, helpful resources A glance of C++0x std::thread One of the major changes with the new C++ Standard is the support of concurrency —- the new C++ thread library, std::thread. It is said [1] that the library is heavily based upon the existing Boost […]

Introduction In a prior article, Constructing your First PowerShell Provider, we covered PowerShell Provider development. In my follow-up article, Debugging and Designing Custom .NET Framework PowerShell Providers, we looked at more advanced PowerShell development topics like Provider design and debugging. Both articles focused mostly on providers. Most solutions, however, will likely include Custom CmdLets that […]

Introduction The Visual C++ 2008 Feature Pack, which ushered in a much-needed and comprehensive refresh of MFC, included a ribbon control that was a custom implementation of the Office 2007 counterpart which inspired it. Windows 7 includes an in-built Ribbon control, and standard applications like WordPad and Paint take advantage of this new control. The […]

Introduction In the previous article we looked at the options for developing cross-platform applications in C# programming. The technology that makes this possible is Mono from Novell. In this article we’ll take an existing Windows C# application and run it on both Mac OS X and Linux. Before we dive into the details it’s important […]

Introduction Unlike a few other object-oriented programming languages, C++ programming doesn’t allow a constructor to call another constructor of the same class. Consequently, programmers are often forced to repeat the same initialization code in every constructor. Such duplicate code introduces maintenance problems and compromises code readability. Fortunately, in 2006 the C++ programming standards committee voted […]
