Environment: Developed and tested on Win2000 using VC6 Recently, I needed to present a user interface incorporating a large number of buttons. Each button caused an activity to start and would run for an indeterminate length of time. I wanted to indicate this activity and associate it with the button that started it. I came […]

Environment: Visual Studio, All Windows platforms –> The Code typedef class _MyCriticalSection { long count; HANDLE Eventhandle; public : _MyCriticalSection(); void Enter(); void Leave(); }MyCriticalSection; That’s it; everything is in the class!!!!! The constructor creates an automatically resetting event and assigns it to EventHandle. Let us look at what goes on inside a general thread. […]

Environment: .NET / C# One of the benefits of implementing interfaces instead of inheriting from a class is that you can implement more than one interface at a time. This gives you the power to do multiple inheritance without some of the downside. To implement multiple interfaces in C#, you separate each included interface with […]

From Kate Gregory’s Codeguru column, “Using Visual C++ .NET“.–> With the release of Visual Studio .NET 2003 (formerly known as Everett) on April 24th, many developers are now willing to consider using the new technology known as managed code. But especially for C++ developers, it can be a bit confusing. That’s because C++, as I […]

Environment: Visual Studio, All Windows platforms The Matrix, in its simplest form, simplifies working with arrays. This is the third of several articles that explains how to use the different features of the Matrix. In the previous article, I described how to use the Matrix to simplify COM marshalling with VARIANTs and SAFEARRAYS. In this […]

Environment: VC6, VC7, MFC Description This article describes a CStatic-derived Progress bar that allows “busy” times with no defined end to be indicated with more than just an hourglass cursor. Adding the Code to Your project The CKCBusyProgress control can be subclassed within a dialog by following these steps: Insert the .h and .cpp files […]

Environment: C#, .NET In this column, we’ll explore how to communicate with COM ports of your computer. We will cover how to send commands to the port and how to read information from ports. Background The whole idea behind this work was to access a GPRS/GSM modem connected to COM port to send and receive […]

Environment: .NET Framework, C# License: GNU PUBLIC LICENSE (GPL) This control implements a well-styled navigation control for your MDI, SDI, or dialog-based application. I created this control because I love it. The goal was to create an exact copy of the Visual Studio Navigation Control. I think that the target has been nearly reached. In […]

Environment: Visual C++ To start with, the program is a small-time animation in VC++. What does an image look like when it is dipped in a tub of water when the tub is subjected to a constant vibration? The more difficult part is to produce the ripple effect, as when a pebble is thrown in […]

Click here for a larger image. Environment: .NET Framework, CSharp (C#) License: GNU PUBLIC LICENSE (GPL) The control seems like the Microsoft Outlook Address Register Control (under Contacts) with a little bit more .NET-Style. I created this control due to my own need. I don’t have enough time to create a big article about this […]
