Environment: [VC6 SP4, Win9X, Win2k, Win NT 4.0] Looking at the publishing date of Robert E. Peters’ article I decided to write a new and updated POP3 Wrapper Class. Fixed or Changed: I restructured the class and replaced the #define constants through enums. I also figured out a few accidentally made bugs in the old […]

Visual Studio.Net has added an expanded extensibility model and macros to the unified Visual Studio IDE. The macro tools allow you to quickly record repetitive tasks, enhancing productivity. The productivity gain you get depends on the weight of the repetitive tasks. Small automatic tasks, small gains. Bigger tasks, bigger gains. When you have automated the […]

I needed to get an UNC path from a local path. I was searching the MSDN and the Internet to get information about this, but I didn’t find anything. I did find posts requesting a procedure to solve this problem, so maybe this code can be useful. The solution I found is tricky, perhaps too […]

Switch on String Literals in C++ There was a time – not so long ago – when you could not switch on or over string literals in C++. In fact, this was the case case prior to the release of C++11. To be fair, it is still technically the case, in that the C++ standard states that you […]

Environment: VC6 SP5, Win98SE Many programmers need to optimize some algorithms for speed from time to time. You cannot always afford to buy expensive code timing tools. This is mostly the case when learning to program. The poor man’s approach for timing a piece of code is to bracket the code with GetTickCount() and subtract […]

Environment: Windows 2000 This simple SDI Notepad-like application demonstrates how, taking advantage of the MFC support for Unicode, to Turkmenize labels of the specified menu items. Actually, Turkmen is not supported by Windows 2000, therefore, to create such resources as menu so that strings in Turkmen could be displayed I had to invent an additional […]

Environment: VS.NET (beta 1), NT 4.0, Win95/98/2000 Introduction Accessing databases is a common part of most applications and with the introduction of C# and ADO.NET, has become quite simple. This article will demonstrate the four most basic database operations.  Reading data. This includes various data types such as integers, strings and dates. Writing data. As […]

Environment: [.NET] The managed world is beautiful. I have all classes I could want in FrameWork. What happens if I want to call some unmanaged code–such as existing C++ code? For instance, I have DLL written in C++, and want use it from C#. Let’s look some code. I have a DLL that exports a […]

Environment: VC6 SP4, NT4, Win2000, Win9x Abstract These are days where almost everything can be skinned or customized. If you have taken a look at Windows XP you will have noticed that even buttons can have a look far away from what we know. Even if I don’t like hard customizations very much, I’ve noticed […]

Environment: VC6, NT4 SP3 This is a simple Windows application, which creates and reproduces 3D-image (surface) of a function plot using OpenGL rendering context. Graphics data may be arbitrary (specified by the user). Data format becomes obvious if you consider (look up the codes of) the function COGView::DefaultGraphic. The application makes it convenient to inspect […]

The power and expressiveness of Visual Basic.Net represents a marked difference between versions 6 and 7 (VB.NET). The fundamental idioms have change moderately on the surface. The basic grammar has changed only a little making VB.NET code recognizable as Visual Basic. However, it is the more advanced idioms that have changed significantly, making VB.NET an […]

Design Patterns are intended to provide solutions to recurring design problems. Design Patterns play a major role in the design of complex systems using object-oriented methods. Patterns help designers to decompose the system into set of co-operating objects instead of decomposing objects and trying to find relationships between them. In fact, most of us are […]
