    Stanley B. Lippman - Visual Studio 2005 Guided Tour 2006
    C++/CLI is a self-contained, component-based dynamic programming language that, like C# or Java, is derived from C++. In fact, you can look at it as a natural step in the evolution of C. Stanley Lippman, who was there from the beginning, provides some insight.

  • Pure C++: Reflecting on Generic Types
    Stanley B. Lippman - December 2005
    A funny thing happened to templates on their way to the common language runtime (CLR)—they lost their {type} identity. This is analogous to what happens with macros under native programs. Just as the C/C++ compilers have no awareness of macro preprocessor expansions, the CLR has no awareness of template instantiations.

  • OpenMP and C++: Reap the Benefits of Multithreading without All the Work
    Kang Su Gatlin and Pete Isensee - October 2005
    Having more than one CPU core on a single chip makes a system with a processor with two cores operate just like a dual-processor computer, and a system with a processor with four cores operate like a quad-processor computer, so you get much better performance. But if your application does not take advantage of these multiple cores, you may not reap the benefits. OpenMP helps you create multithreaded C++ applications more quickly so the benefits of multithreading can be realized.

  • Debugging: Root Out Elusive Production Bugs with These Effective Techniques
    Matt Adamson - July 2005
    Errors happen. But in production, error logs often provide little or no help in pinpointing the exact line of code in which the problem originates. You can't usually isolate the root cause by modifying code in a production environment because recreating the exact same environment is very difficult due to the large number of potential software and hardware configurations. This article provides some concrete steps you can take to get at the heart of the problems in your production code.

  • Wrappers: Use Our ManWrap Library to Get the Best of .NET in Native C++ Code
    Paul DiLascia - April 2005
    By now you're probably used to reaching into the .NET Framework using Managed Extensions with your C++ code. But what do you do if you have legacy apps that use older versions of the compiler, or if you want to avoid some of the CLR requirements? Well, you can wrap Framework classes in a native way so you can use them in any C++/MFC app without /clr. Paul DiLascia shows you how.

  • Escape DLL Hell: Simplify App Deployment with ClickOnce and Registration-Free COM
    Dave Templin - April 2005
    DLL Hell that results from versioning conflicts is generally not a problem in .NET because components do not require registration, and are either totally isolated to an application or are managed in a well-defined side-by-side way with the help of the Global Assembly Cache. But if you're still using COM, wouldn't it be great if you could deploy your existing COM components using a model similar to the .NET Framework? In Windows XP, you can, and this article explains how.

  • Pure C++: Generic Programming Under .NET
    Stanley B. Lippman - April 2005
    Visual Studio® 2005 brings the type parameter model of generic programming to the Microsoft® . NET Framework. Parameterized types are, of course, standard fare for C++ programmers. So, for those who are unfamiliar with them, I'll give a brief introduction to generic programming in my next few columns.

  • C++ Rules: Power Your App with the Programming Model and Compiler Optimizations of Visual C++
    Kang Su Gatlin - January 2005
    Many programmers think that C++ gets good performance because it generates native code, but even if your code is completely managed you'll still get superior performance. In Visual Studio 2005, the C++ syntax itself has been greatly improved to make it faster to write. In addition, a flexible language framework is provided for interacting with the common language runtime (CLR) to write high-performance programs. Read about it here.

  • Timers: Implement a Continuously Updating, High-Resolution Time Provider for Windows
    Johan Nilsson - March 2004
    The timestamps that you can obtain from Windows NT are limited to a maximum resolution of 10 or 15 milliseconds, depending on the underlying hardware. At times, such as when you need to timetag frequent events, it is desirable to achieve a higher resolution. For example, what if you want to be able to contact a thread or perform some other task at intervals more frequent than 10 milliseconds? Suggested ways of achieving better resolution include using performance counters in conjunction with the sytem time to calculate smaller time increments. But using performance counters is a technique that presents its own problems. This article shows one possible way of overcoming limitations inherent in this approach.

  • Review It: Expert Tips for Finding Security Defects in Your Code
    Michael Howard - November 2003
    Reviewing code for security defects is a key ingredient in the software creation process, ranking alongside planning, design, and testing. Here the author reflects over his years of code security reviews to identify patterns and best practices that all developers can follow when tracking down potential security loopholes. The process begins by examining the environment the code runs in, considering the roles of the users who will run it, and studying the history of any security issues the code may have had. After gaining an understanding of these background issues, specific vulnerabilities can be hunted down, including SQL injection attacks, cross-site scripting, and buffer overruns. In addition, certain red flags, such as variable names like "password", "secret," and other obvious but common security blunders, can be searched for and remedied.

    Aleksandr Mikunov - September 2003
    In this article, the author shows how to dynamically rewrite Microsoft Intermediate Language code on the fly using the Profiling API of the CLR. Unlike approaches based on Reflection.Emit, this scheme works with the existing assemblies and doesn't require the creation of proxy or dynamic assemblies. The need for IL code rewriting emerges when you want to make your changes transparent to the client and preserve the identity of classes. This technique can be used for creation of interceptors, pre- and post-processing method calls, and code instrumentation and verification.

  • Coroutines: Implementing Coroutines for .NET by Wrapping the Unmanaged Fiber API
    Ajai Shankar - September 2003
    Coroutines are a powerful feature of many programming languages including CLU, Scheme, Python, Ruby, and ICON. Coroutines can save processor overhead and reduce redundancy because they allow you to stop execution of a procedure midstream, return a value, and resume exactly where the procedure left off.This article shows how coroutines can be implemented for the .NET Framework by using the Fiber API and Managed Extensions for C++, and how they can be easily used with other .NET-compliant languages. This article also shows a sophisticated use of the runtime host for running multiple managed threads on a single OS thread.

  • Visual C++ 6.0: Don't Let Memory Allocation Failures Crash Your Legacy STL Application
    James Hebben - September 2003
    Most C++ developers make extensive use of the Standard Template Library (STL) in their code. If you are one of them and are using STL and Visual C++ 6.0 directly out of the box, your application is at high risk of crashing under low memory conditions. The problem arises because checking for failure of operator new is such an uncommon practice. To make things worse, when new does fail, the response is not standard. Some language compilers return NULL while others throw an exception.In addition, if you are using STL in an MFC project, be aware that MFC has its own set of rules. This article discusses these problems, explains how the default behavior has changed in Visual C++ .NET 2003, and outlines the changes you must make if you're using Visual C++ 6.0 so that you can safely use the STL when operator new fails.

  • DCOM Interop: Generate Custom Managed C++ Wrappers for Easier COM Interoperation Using DCOMSuds
    Vishwas Lele - August 2003
    Now that you're writing managed code, you'll certainly want to use your existing COM components, but you can't simply call them directly. Instead, you have to wrap the COM component in a runtime-callable wrapper that acts as a proxy between the component and your managed code. While the CLR provides wrapper classes for this purpose, there will be times when you'll want custom objects to wrap your COM components. One way to get the low-level access you need to precisely control resource cleanup, pass security information, and get access to CLR features is to write your own wrapper class in managed C++. This article shows you how.

  • Smart Cleanup: Achieve More Reliable Resource Management with Our Custom C++ Classes
    Eric Niebler - June 2003
    Managing resources in C++ is not easy. When you're unsuccessful, your app can leak all kinds of resources including file system handles, database connections, and, of course, memory. Even in garbage-collected languages like Managed C++, resource management is difficult because garbage collection only deals with memory management, not the other resources that cause performance problems.In this article, the author describes the SmartAny template library he created, which uses a policy-based approach to dynamic resource management. Readers will learn how to use the SmartAny classes and policies to ensure the proper cleanup of their resources, be they files, OS handles, or native and unmanaged objects.

  • Design: Inspect and Optimize Your Program's Memory Usage with the .NET Profiler API
    Jay Hilyard - January 2003
    Developers using .NET often make memory leak tracking a low priority because the common language runtime takes care of garbage collection. What few developers realize, however, is that their objects' lifespans, along with their size and what other objects have been instantiated, all affect how they are cleaned up. Depending on the particular circumstances, these combinations can negatively affect performance, especially over the lifetime of an application. This article presents a way for developers to see memory usage and understand garbage collection using the .NET Profiler API. Along the way, a sample application to demonstrate these principles is built.

  • Security Tips: Defend Your Code with Top Ten Security Tips Every Developer Must Know
    Michael Howard and Keith Brown - September 2002
    There are many ways to get into trouble when it comes to security. You can trust all code that runs on your network, give any user access to important files, and never bother to check that code on your machine has not changed. You can run without virus protection software, not build security into your own code, and give too many privileges to too many accounts. You can even use a number of built-in functions carelessly enough to allow break-ins, and you can leave server ports open and unmonitored. Obviously, the list continues to grow. What are some of the really important issues, the biggest mistakes you should watch out for right now so that you don't compromise your data or your system? Security experts Michael Howard and Keith Brown present 10 tips to keep you out of hot water.

  • ASP.NET: Intercept, Monitor, and Modify Web Requests with HTTP Filters in ISAPI and ASP.NET
    Panos Kougiouris - August 2002
    There can be many reasons to reroute incoming Web requests. For instance, sometimes it's necessary to redirect a browser to a page based on user criteria without passing long lists of parameters in the URL. In the past, the only way to intercept such page requests and send them elsewhere was with ISAPI. Now, in ASP.NET, the IHttpModule interface provides notification of server requests, and lets you easily reroute them based on criteria other than browser type or version. Here the author demonstrates the use of IHttpModule for interception and explains the use of ISAPI filters for anyone who isn't yet using ASP.NET.

There are three tools included as samples: LoadLibrarySpy, which monitors an application and detects which DLLs are really loaded; WindowDump, which retrieves the content and a detailed description of any window; and FileUsage, which redirects console-mode applications to tell you which process is using any opened file.

  • SENS: System Event Notification Services and WMI Enable Flexible, Efficient Mobile Network Computing
    Aspi Havewala - August 2002
    Networked applications must deal with a host of connection problems ranging from timeouts to congestion to unavailability. If these applications can check the current connection status and, when disconnected, cache transmissions, they become more efficient. Fortunately, both the System Event Notification System (SENS) and Windows Management Instrumentation (WMI) can send notifications to keep applications informed of network status. In this article, the author explains the use of several SENS interfaces, including ISensNetwork and ISensLogon, which trigger events for connects/disconnects and logons/logoffs, respectively. The author then shows how you can subscribe to each of these events, and follows with a discussion of when you might use WMI events instead.

  • ISAPI Extensions: Creating a DLL to Enable HTTP-based File Uploads with IIS
    Panos Kougiouris - October 2001
    The MIME-compliant content type, called multipart/form-data, makes writing HTML that uploads files almost trivial. On the server side though, ASP does not have a way to access data in the multipart/form-data format. The most flexible way to access the uploaded file is through a C++ ISAPI Extension DLL. This article describes a reusable ISAPI extension DLL that allows you to upload images and files without writing C++ code. It is coupled with a few COM components that make it readily reusable for ASP development. With .NET, this whole process is much easier, and this article shows preliminary code that uploads files using ASP.NET features.

This article describes a way to programmatically identify the current cursor's ID and bitmap at any point in time. The first technique described is based on polling for information and shows how to get the handle of the current global cursor. This handle will then allow you to get information about the cursor. You can also monitor WinEvents for changes to the global cursor.

  • ISAPI Filters: Designing SiteSentry, an Anti-Scraping Filter for IIS
    Rodney Bennett - October 2001
    The Microsoft Internet API for IIS, ISAPI, sits between the client and the Web server. Therefore, you can access the HTTP data stream before IIS gets to see it. The project in this article takes advantage of the ISAPI architecture to create a filter that monitors access to a Web site to determine if visits are from typical users or from automated processes designed to pilfer information from your site. The author tracks the regularity of visits to the site to determine the likely source. Once the determination is made, the app either redirects the user or continues to track information about those hits.

    Windows Management Instrumentation (WMI) is based on an industry-wide standard for notifications used to manage objects and devices across a network. By receiving WMI events, an application can be notified of changes to data in WMI itself. This allows the developer to notify the consuming application that certain system configuration data has changed, without the application having to poll WMI continuously for this data. The author presents an explanation of the different types of events in WMI, then goes on to develop an event provider.

  • Windows XP: Make Your Components More Robust with COM+ 1.5 Innovations
    Juval Lowy - August 2001
    The next version of COM+, COM+ 1.5, offers many improvements over COM+ 1.0. A comprehensive user interface that displays more data for each application as well as complete support for legacy components make the management of existing applications easier and more efficient. Enhanced queueing support provides more flexibility for managing queued calls, and pooling and recycling means better application lifetime management. Application partitioning in COM+ 1.5 surpasses that offered in COM+ 1.0, and transaction isolation can be configured for safer transactions. COM+ 1.5 also allows you to expose any COM+ component as a Web service, as long as it meets certain criteria. This article discusses these and other new features in COM+ 1.5 that take care of much of the plumbing code, allowing developers to concentrate on business components.

  • Fax Services: Send Any Printable File From Your Program in Windows 2000
    Marcin Kaluza - August 2001
    All versions of Windows 2000 have fax services built in, so sending faxes manually is as easy as setting fax options from the control panel. Faxes can also be sent programmatically in Windows 2000 using either COM Automation or the standard C API. The example in this article uses COM Automation with Visual Basic and MFC to programmatically manage faxing. The objects used for fax transmission, such as the FaxServer and FaxDoc objects, as well as their properties and methods, are explained. Because faxing of files you can't print can be problematic, this process is explained. Finally, this article implements a fax routing extension-a plug-in that exports standard functions and implements routing methods for processing received faxes.

  • Multiprocessor Optimizations: Fine-Tuning Concurrent Access to Large Data Collections
    Ian Emmons - August 2001
    Application performance involves more than just speed. In a Web server environment, top performance also means ensuring that the maximum numbers of users can be served concurrently. This can be accomplished through efficient use of multiprocessor machines and thread management. This article presents techniques that can solve a number of concurrency problems. One approach, using thread management, controls access to a database on a per-thread basis, which protects the integrity of the data. In the article, reusable thread classes are built and presented. The classes are then tested and their performance in a live environment is examined.

  • .NET Delegates: Making Asynchronous Method Calls in the .NET Environment
    Richard Grimes - August 2001
    One of the many great features of the .NET Framework is that it has asynchronous infrastructure built in. In .NET you can call any method asynchronously by defining a delegate for the method and calling the delegate's asynchronous methods. This is beneficial to your application because when a synchronous call is made, the calling thread is blocked until the method completes whereas an asynchronous call is made on a different thread, and this allows the original thread to continue its work while the asynchronous call is in progress.This article explains delegates in .NET and how to use them to perform asynchronous calls, eliminating age-old threading problems.

    Jesse Liberty - July 2001
    C# builds on the syntax and semantics of C++, allowing C programmers to take advantage of .NET and the common language runtime. While the transition from C++ to C# should be a smooth one, there are a few things to watch out for including changes to new, structs, constructors, and destructors. This article explores the language features that are new to C# such as garbage collection, properties, foreach loops, and interfaces. Following a discussion of interfaces, there's a discussion of properties, arrays, and the base class libraries. The article concludes with an exploration of asynchronous I/O, attributes and reflection, type discovery, and dynamic invocation.

  • Windows UI: Our WinMgr Sample Makes Custom Window Sizing Simple
    Paul DiLascia - July 2001
    Programmers using Visual Basic have always had an advantage over C++ programmers when it comes to component and window sizing. There are many third-party Visual Basic-based solutions to this age-old problem, but unfortunately, there are few elegant alternatives for the C++ crowd, short of using a full-fledged windowing toolkit. This article explains how to circumvent the tedious task of hardcoded pixel arithmetic. It starts by introducing a window sizing rules system, and then moves on to show how CWinMgr, a data-driven class, can intelligently manage an MFC application's window sizing.

  • Visual Studio .NET: Managed Extensions Bring .NET CLR Support to C++
    Chris Sells - July 2001
    If you're a longtime C++ programmer, the thought of migrating to Visual Studio .NET might make you wary at first. However, a new feature of Visual C++, the managed extensions for C++, allows you to build apps with the .NET Framework. When you use managed C++, your code is handled by the common language runtime (CLR). This provides advanced features like garbage collection, interoperability, and more. This article explains why you'd want to use the managed extensions, how to use them, how to mix managed and unmanaged code, and how your managed code can interoperate with programs written in other languages.

  • DirectX 8.0: Enhancing Real-Time Character Animation with Matrix Palette Skinning and Vertex Shaders
    Benjamin Freidlin - June 2001
    DirectX 8.0 allows the creation of smooth and realistic character movements that are more life-like than simple articulated structure animations. This is made possible by its improved support for vertex tweening and blended vertex deformations, also known as soft-skinning. After a brief history of the use of these techniques in DirectX, soft-skinning using the fixed function pipeline is discussed. This is followed by the use of matrix palettes from within vertex shaders to create a customized soft-skinning solution that takes advantage of the benefits of vertex shaders, such as hardware acceleration and custom lighting algorithms without the limitations of fixed-function solutions.

  • C++ Attributes: Make COM Programming a Breeze with New Feature in Visual Studio .NET
    Richard Grimes - April 2001
    C++ attributes in Visual Studio .NET are used to generate C++ code through attribute providers. Attribute providers generate code for COM classes, and the code is injected by the C++ compiler at compile time. This has the effect of reducing the amount of code that you need to write. In addition, with C++ attributes you no longer need to maintain separate IDL and RGS files, which makes project management simpler. This article explains C++ attributes, the process used by the attribute provider to generate code, and the code that is automatically generated. It also covers how attributes affect the registration process, how attributes can be used to generate code module entry points, and how connection points can be implemented using C++ attributes. Also explained is how these features contribute to the Unified Event Model for the .NET platform.

  • Winsock 2: QoS API Fine-Tunes Networked App Throughput and Reliability
    Wei Hua - April 2001
    The Generic Quality of Service (GQoS) API is a subset of the Winsock 2 API that allows a Winsock application to inform the network of its traffic requirements, enabling entitled applications to receive preferential treatment for their traffic. Existing Winsock applications can be GQoS-enabled by adding or modifying Winsock calls at appropriate places. An application's sending and receiving traffic needs can also be defined by specifying parameters within the QualityOfService (QOS) structure. This article discusses how traffic information is conveyed throughout the network, what kind of QOS structure should be used in your app, and how to set up network configurations for testing GQoS applications.

  • C++ and STL: Take Advantage of STL Algorithms by Implementing a Custom Iterator
    Samir Bajaj - April 2001
    There are many benefits to using the Standard Template Library (STL) for C++ development, including the ability to use generic data structures and algorithms. To use the STL algorithms, an STL-conforming container is required. Iterating through the Internet Explorer cache is an informative exercise, but the cache is not an STL-conforming container. So, to use the STL algorithms to search and enumerate the Internet Explorer cache, an adapter is needed. Building such an adapter-an STL-conforming iterator-is the topic of this article. Also provided is an overview of the components of the STL and the Win32 Internet APIs used.

  • SOAP Toolkit 2.0: New Definition Languages Expose Your COM Objects to SOAP Clients

    In SOAP Toolkit 2.0, the Services Description Language (SDL) has been replaced with the Web Services Description Language (WSDL) and the Web Services Meta Language (WSML). WSDL and WSML files describe the interfaces to a service and expose COM objects to SOAP clients. This article describes a custom tool, IDL2SDL, which takes an IDL file and produces WSDL and WSML files without waiting for a DLL or TLB file to be generated. Also shown is a customized development environment in which WSDL and WSML files automatically reflect the changes to IDL files.

  • Windows Script Host: New Code-Signing Features Protect Against Malicious Scripts
    Eric Lippert - April 2001
    Downloading scripts from the Web or e-mail leaves users vulnerable to security risks because scripts can't be signed. But now developers can use Windows Script Host (WSH) to hash scripts so users can verify their source and safety. With WSH, scripts can be signed or verified using all the same tools ordinarily used to sign EXE, CAB, DLL, and OCX files. This article discusses public-key cryptosystems, the process of signing and verifying scripts in WSH, and several warnings about attacks that could potentially be made against cryptographically secured scripts and ways in which to avoid them.

    Microsoft Management Console (MMC) 2.0 provides a host of exciting new features for MMC users and snap-in developers. The new MMC 2.0 automation object model allows much of the user interface of MMC 2.0 to be accessed through script, and exposes events so that many tasks can now easily be automated. The new view extension model uses HTML to enable extensions to seamlessly integrate new user interfaces with those of existing snap-ins. MMC 2.0 also includes a specific view extension snap-in, the Extended View snap-in, which provides an interface similar to Web folders. Drag and drop support has been expanded, and console files now use the XML file format. Enhancements to console taskpads make it easier to accomplish tasks.

  • Microsoft .NET: Implement a Custom Common Language Runtime Host for Your Managed App
    Steven Pratschner - March 2001
    While most application developers may not need to write a custom host, understanding what is involved provides a great deal of insight into the architecture of the CLR. After covering how the CLR is started and loaded into a process, how to set the available configuration options, and how a host defines application domains, this article explains how to design a custom host. Important concepts include making the right decisions about the application domain boundaries for the host, configuring them correctly, loading and executing user code, and resolving references to assemblies. Setting security policy and unloading application domains as the application shuts down are also explained.

  • Resource Leaks: Detecting, Locating, and Repairing Your Leaky GDI Code
    Christophe Nasarre - March 2001
    Leaks are possible, even in robust Windows-based applications. As bugs go, leaks are some of the most difficult to find, especially when they occur in graphics device interface (GDI) objects and menus. While free and third-party tools exist to detect such leaks, it is usually difficult to make the connection between the numeric handle value returned by the tool, and a bitmap or menu in your program. This can limit the usefulness of these tools. Custom tools can be built that detect, track down, and eradicate GDI and menu leaks. Here, three such tools are built using well-known and documented APIs.

  • COM: Handle Late-bound Events within Visual Basic Using an ATL Bridge
    Carlo Randone - March 2001
    Since a Visual Basic client doesn't handle events directly from late-bound COM objects, it needs some way to capture all the events and parameters launched by any COM object server instantiated at runtime and not known at design time. This article explains how to build a bridge component that does just that. The bridge component transmits the intercepted event data back to the Visual Basic client using another supporting COM object that is capable of holding event data and attributes. The Visual Basic client receives the notification from the bridge and extracts all the information relative to the event from the supporting object.

    Jeff Prosise - April 2000
    Windows 2000 is the first version of COM to support asynchronous method calls, which permit clients to make nonblocking calls to COM objects and objects to process incoming calls without blocking the calling threads. COM clients benefit from asynchronous method calls because they can continue working while waiting for outbound calls to return. Objects benefit because they can queue incoming calls and service them from a thread pool. Our SieveClient and SieveServer sample apps demonstrate how to create and use asynchronous clients and servers in COM-based distributed applications.

  • Which Framework Should You Use?: Building ActiveX Controls with ATL and MFC
    George Shepherd - April 2000
    Currently MFC and ATL represent two frameworks targeted at different types of Windows-based development. MFC represents a simple and consistent means of creating standalone apps for Windows; ATL provides a framework to implement the boilerplate code necessary to create COM clients and servers. The two frameworks overlap in their usefulness for developing ActiveX controls. We'll take a look at both frameworks as they apply to creating ActiveX controls-highlighting strengths and weaknesses, and walking through the process of creating a control-so you can determine when you might want to use one framework or the other.

  • Software Driving Software: Active Accessibility-Compliant Apps Give Programmers New Tools to Manipulate Software
    Dmitri Klementiev - April 2000
    Active Accessibility was developed to allow people with disabilities to work on PCs-it's used in magnifiers, screen readers, and tactile mice. It can also be used to create applications that drive other software, and its ability to emulate user input is particularly well suited to the design of testing software. Starting from the basics of Active Accessibility, this article leads you through the development of a software testing application. You'll see how this testing application interacts with common controls and other UI elements, then processes the resulting WinEvents.

This is followed by a detailed treatment of the SOAP encoding rules with a focus on how SOAP maps onto existing ORPC concepts.

  • Windows 2000 UI Innovations: Enhance Your User's Experience with New Infotip and Icon Overlay Shell
    Dino Esposito - March 2000
    Windows 2000 includes some helpful new UI features you can customize and implement in your own applications. In this article you'll see how to provide infotips for files, after making the appropriate registry entries. Then create a custom column handler extension, resulting in a new column for the Explorer's Details view. In order to further extend the shell, additional UI goodies will also be examined and implemented including: search handlers, cleanup handlers, folder customizations using property sheet handlers and icon overlays, and context menu shell extensions. All the code samples are rolled up into a handy package which we've named, by tradition, ShellToys.
