Environment: Visual Studio.NET 2002, Visual Studio.NET 2003 Introduction The most convenient method I find for automatically incrementing project build numbers for Visual C++ projects is through an add-in that modifies the build number on each successful release build. I found an add-in for doing that at CodeGuru, but it only works for Visual Studio 6.0. […]

Environment: Any flavour of MFC (Doc/View) including VC6 and VC7 (demo is VC7) Introduction I had a project in the company where I work that needed different forms for different customers, so the team decided to create a runtime form editor that can enable editing the forms for each customer. To do that, I needed […]

Environment: –> Well, a lot has been said already about message maps and how the handler you wrote in your derived Wnd class gets called. Here I present a simulation on how to understand it from a C++ viewpoint. What the C++ code takes to achieve this is presented below. Of course, I present only […]

by Dino Esposito of Wintellect It’s known that the .NET Framework version 1.1 is a minor upgrade with a relatively limited set of changes and updates. The stars in the what’s-new list of version 1.1 are technologies that were already available as separate downloads such as the Oracle and ODBC .NET data providers and the […]

Environment: VC6 SP5, Windows XP SP1p Based on the article “Encrypting and Decrypting Sensitive Data Using CryptoAPI” by Jorge Lodos in the Miscellaneous/CryptoAPI section and many questions in the forum (how to encrypt/decrypt a string—also from me), I have adapted this project for this purpose. My project doesn’t use the Registry; the string is returned […]

Environment:Internet, networking TCP Ping is necessary when measuring server functionality from different IP networks (mirror sites). As you see, it uses a TCP transport protocl instead of ICMP. To ping the remote (or local) server, it should be able to provide “NOOP” command (NO OPeration) followed by CRLF. Such user-defined protocols can be: SMTP/25; FTP/21; […]

Getting a docking toolbar in a dialog is not easy. When I asked Jeff Prosise, he replied that it comes with an SDI app, and Microsoft gives you the code. It is not easy, but it is doable. I did not see Microsoft’s code, but went on to write my own. I do a small […]

Environment: VC6 + Microsoft SDK, VC7, Windows 98/ME/NT/2000/XP This article describes the program that shows the information about different network interfaces operating at the current moment. The basis of this utility is the use of such API functions as GetAdaptersInfo(), inet_addr(), and gethostbyaddr(). The program displays the adapters’ names in the system, protocol type (PPP, […]

Environment: This control was developed with VC6 and ATL. –> I have seen a lot of code on the Internet about round buttons but none on Round SysMenu buttons, so here it is. The code also explains how to do flicker-free painting in the caption and throws light how to do the same in other […]

Environment: .NET Framework V1.0, Win 2K, XP Introduction The common language runtime allows programmers to add descriptive declarations to programming elements called Attributes. Attributes are like annotations that can be applied to assemblies, types, methods, or properties. Attributes are emitted into the assembly metadata and they can be extracted by using Reflection services of the […]

Click here for larger image Environment: VC++, WIN32 x86 I have seen MANY people ask for ways to determine different types of system information. Some people want to know the OS version; some want to know memory information; others want to know detailed information about the processor. All of this information, and more, is easily […]

Environment: Visual C++, Windows NT, and Windows 2000 The runasv program offers execution commands for every user running Windows NT and Windows 2000. This program allows the execution of every command with the user specified. The runserv.exe program runs as a service (with localsystem user) and listens by using Windows sockets (port 8000) as a […]
