This article describes how to get the callstack for memory leaks in a certain component (EXE or DLL) of your Visual C++ program. The code provided with this article works on WindowsNT. It should work on Windows9x systems as well, although it has not been tested on such systems. There is another restriction, that it […]

This sample server demonstraites a server that can handle multiple TCP/IP connections. It also shows how to make a simple telnet server that could be used for things like administrating a server, making a chat room, or even creating a MUD. The project that I chose was a chess server that could handle multiple games […]

This time is about to shut down a network machine. Of course, we have to use InitiateSystemShutdown routine. The job is done in the sample dialog by pressing Shutdown button. Also the dialog with Cancel event armed can be useful sometimes (think at stored procedures, transactions, etc.). #include void CShutdownDlg::OnShutdown() { HTREEITEM hSel = […]

Full Screen mode is widely used in programs such as Word, VisualC, Corel Draw etc. If you take a closer look on the these implementations you will notice that they solve this problem differently. Below you will find an example for this problem. I have used it in my editor program ( MyLight ) for […]

So you finally got your hands on this awesome piece of C/C++ code that promises to solve your burning problem! You download it and open it inside DevStudio to see how it works and guess what? It looks like crap! I mean, the person who wrote the code used the Martian convention to write it. […]

I recently needed a wizard that could be resized by the user. After looking around on CodeGuru I found nothing that would do this completely so I created my own (since I have taken so much code and ideas from CodeGuru, I felt that the time had come to give something back). After a while […]
