A mainstay of software engineering is a concept called tracing. The first time I encountered the trace capability was in the C programming language, implemented as a macro. The basic idea is that you insert statements into your code that provide information about your application while it is running. This is referred to as tracing. […]

Introduction Microsoft Intermediate Language (MSIL) is a language used as the output of a number of compilers (C#, VB, .NET, and so forth). The ILDasm (Intermediate Language Disassembler) program that ships with the .NET Framework SDK (FrameworkSDKBinildasm.exe) allows the user to see MSIL code in human-readable format. By using this utility, we can open any […]

It wakes up every X times, and checks the following: Is myApp running? If not, it turns it on. Is myApp hanging? (This is decided by myApp not consuming any CPU usage during the last X […]

. Environment: C6, Win32 Overview The ability to draw an image on the screen that is a different size than the original source image is incredibly easy with Win32’s GDI StretchBlt function and its variants. However, using StretchBlt with large images, especially with a large amount of stretch, is very slow. Also, shrinking images with […]

Environment: .NET, C# Introduction In this article we will learn how to achieve late binding and how to create and execute code on the fly (during runtime) by using the Refection namespace of C Sharp in .NET.
