This article was contributed by Anand Narayanaswamy. In this article, we will analyze COM components and their application in C#. These components became popular among developers after Microsoft released Active Server Pages. However, the whole scenario changed when Microsoft released its Windows 2000 operating system and subsequent COM+ technology. In this article, we will examine […]

Environment: MSVC6, Borland C++ 5.02, Borland C++ Builder 6, NT4, Win2000 In this essay, I am going to show you how the most commonly used C++ compilers (MSVC and Borland) use the stack. Beginners will learn how the stack is used, what the function stack frame is, what the stack frame pointer is, and how […]

Environment: VC6 Win9x For an application that consists of more than one file, it is often more convenient to distribute it as a single executable. This article demonstrates how to embed any file as a resource and how to turn that resource back into a file. For each file you want to include, add a […]

. Environment: VC6, NT4/Win2K—should work on any 32-bit Windows operating system that has Winsock2 libraries. Overview Sample code for a network “ping” is relatively easy to find. CodeGuru has several good examples and the SDK sample code has another good example. So what about trace route? With a little research I discovered that doing a […]

Environment: C# Introduction Using enumeration types is the best way to store data such as days, months, account types, genders, and so forth. Using this technique for data exchange, I decided to use enumerations for external representation as well. There is no problem converting an enumeration type value to a string. You only have to […]

Environment: Windows 95/NT The GetLongPathName API call is only available on Windows 98/ME and Windows 2000/XP. It is not available on Windows 95 & NT. This code example emulates the function for use on 95 & NT and will work on the other systems as well. This example uses MFC and CString, but could be […]

Environment: VC6, Win-9X/2000 (hasn’t been tested on other OS) Displaying a large bitmap file on a dialog box, in its original size, is quite difficult in the VC++ environment. However, it is possible to display a large bitmap to a predefined area of the dialog by using the StretchBlt( ) function.The major disadvantage of this […]

Click here for a larger image. Environment: VC6 SP4, NT4 SP3, Win2K Currently, I am working towards building an omni-directional autonomous mobile robot. Omni-directional refers to a vehicle that could translate (or move) and spin (or rotate) simultaneouly. Just for an example, your car is not an omni-directional vehicle. As part of this ongoing project, […]

Environment: .Net SDK Beta 2 or Visual Studio .Net beta 2 Introduction: Before we try out something with the Buffer class, you should understand the Buffer class and its Members. The first question that comes to mind is how they are different from the Array class and how they work as compared to the Array […]

Mike Borromeo’s “Debugging Techniques in C#” presented a useful Debug class that can log debug or trace messages with caller and code location information automatically. (See: https://www.codeguru.com/net_general/Debugging.html) It was a great idea and it helped my project tremendously. There is one assumption made by the Debug class that was presented that is not always true. […]

Debugging GUI applications for me mostly consists of printing out debug statements in the form of a dialog box with some text. While this technique was helpful for small to medium size apps I find writing large apps with a dialog box popping up after every other statement is counterproductive. With this in mind, I […]

Transform any static text control: Into an active hyperlink: Environment: VC6, VC7, and likely others In need of a quick hyperlink control in an About box, I noticed that CodeGuru had a couple of options available to MFC users. Unfortunately, I needed a solution that dealt directly with the Win32 API. Because I have benefited […]
