Mark Strawmyer Presents: .NET Nuts & Bolts

Environment: VC6 This article explains how multiple inheritance (MI) can be used in MFC (Microsoft Foundation Classes library) applications, why MFC does not support MI, and how to overcome this limitation by using C++ templates. If you are writing object oriented-code, you frequently use a concept of inheritance by creating more specialized objects (components) from […]

Environment: Visual C++ 7.0, Windows XP sp1, Windows 2000 sp3 Abstract This project tries to simulate the property behavior that exists in C# (and other languages…) in C++, without using any extensions. Most libraries or compilers that implement properties in C++ use extensions, as in Managed C++ or C++ Builder, or they use the set […]

Environment: MFC I wrote this class when I needed to extract separate bits of data from an array, one by one. After some calculations, I found I needed to put modified bits in another array of data. I think this class may be useful, so here it is. This class operates with data located in […]

I am a factoid junky. I derive tremendous joy from exploring the nuts and bolts of languages. For example, did you know that the FrameworkSDK folder (usually at C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Tool Developers Guide\docs) contains the Common Language Infrastructure (CLI) specification. If you want to know exactly what is and is not part of […]

Environment: VC++6, Win32 Overview The OpenGL API has been available to PC programmers who wanted to display rendered 3D graphics since Windows NT 3.51 came out in the mid-1990s. It’s a terrific platform for 3D visualization for two primary reasons: 1) it exposes some very advanced rendering features, and 2) it is very easy to […]

. Environment: VC6, VC7, Windows 9x/NT/2000/XP In the given article, practically all operations on moving a group of files from one application to another are described. Considered are both the reception of files by the given application and transfer of files from the given application in other programs. In the article, the operations drag and […]

This is a series of articles that will cover various techniques supported by Inter Process Communication (IPC) IPC is a mechanism by which the various processes share data among themselves. The application that uses the IPC mechanism can be placed in two categories: client and server application. A client is an application or a process […]

Environment: VC6 Introduction I searched for a DNS Resolver for quite a long time. I got the solution, but it was too uncomfortable to use it. Thus, I made my own DNS Resolver; it’s is very compact in size and is free from the exceptions and errors we usually encounter with CSocket. DNS Protocol Explanation […]

Environment: VC6 This is a very simple way to detect the running instance of an application. It can be achieved by declaring a data variable in the compiler’s own data section called shared. #pragma data_seg(“Shared”) LONG g_Counter = -1; #pragma data_seg() After this, the Linker will be noticed to make the Shared section readable, writable, […]

Environment: Windows 98, Microsoft Visual Basic 6 This projects provides three main functions, each with its own window, as you can see in the image above. Ico, Exe, Dll—you can consider this window as a icon browser/extractor. Make Icon Group—enables you to create icons, with different versions of an icon (small/large, 16/256 colors, …) in […]

Introduction Many applications, such as navigation and radio frequency engineering, require a thorough understanding of geographic calculations. Some very natural questions seem to come up in a variety of disciplines: How far apart are two points on the Earth? What direction do I need to go to reach a particular point? If I go in […]
