This class was developed for the easy accessing of version information from a resource file. It is derived from CWinApp and implements accessor the function you will most likely need to use. As the code is fairly straightforward, I’ll let you look at the source for more information. Here’s all you need to do to […]

Environment: Windows NT 4, Visual C++ 5, Win32 SDK This article demonstrates the development of screen saver using Win32 SDK. This article is very simple. It has 3 routines which are called by Windows 95 during screen saver activation. The first one is where we set up our timer and display a series of bitmaps […]

After I could not locate a method for displaying animated cursors from a resource, I found a way myself. Essentially (with error checking removed), here’s the code path. HCURSOR LoadAnimatedCursor(UINT nID { HINSTANCE hInst=AfxGetInstanceHandle(); HRSRC hRes=FindResource(hInst,MAKEINTRESOURCE(nID),”ANICURSORS”); DWORD dwSize=SizeofResource(hInst,hRes); HGLOBAL hGlob=LoadResource(hInst,hRes); LPBYTE pBytes=(LPBYTE)LockResource(hGlob); return (HCURSOR)CreateIconFromResource(pBytes,dwSize,FALSE,0x00030000); } To import an .ANI file to the resource script: Insert->Resource->Import: […]

What does the code do The ‘LogSystem’ class can be used by developers to add powerful logging capabilites in their MFC applications. It offers the following features: Use of arbitrary number of log levels Use of arbitrary number of log files Fully customizable mappings between log levels and log files Efficient synchronization mechanism for file […]

Environment: VC6, Unicode This is small and usefull C++ class which can encapsulate any windows multimedia mixer control. I wrote a simple class, named CAlexfMixer which can wrap any multimedia mixer control. You can manipulate with Master Volume, Mute or someone else mixer control with this class if control support this operations. You can retrieve […]

I recently needed a class that stored a character array as a circular buffer. If you are unfamiliar with circular buffer, it is a permanently allocated buffer that has both a read and write position. I have done a few of them in the past, but had lost all of my examples. So I wrote […]

Recently, I was in the need of a control that allowed the users the ability to check multiple items in a CListbox type of fashion. I would of used the common MFC control CCheckListBox but I needed the items to be presented in a hierarchy and be totally customizable (font, colors, images, etc.) for each […]

EditPad is free syntax highligting programmer’s editor I’m using heavily at work. And my several friends too :-). Development environment: MS-VC6 SP3, MS-Windows 98 Target environment: Win32 platforms Description EditPad doesn’t bring so much new programming techniques, I’ve just used “the best” of sources at this site and added some my work to make an […]

If you have ever tried to implement structured storage in a MFC application you quickly realize that its not a trival task. Opening, closing, creating and removing storage objects and streams can get very confusing very fast. The COleStreamManager wraps these complicated procedures into a tidy class. The interface’s supplied to use this class is […]

Sometimes Explicit Linking to DLL’s is advantageous over implicit linking. For example, if at runtime the DLL is not found the application can display an error message and still continue. Explicit linking is also useful if you want users to provide a plugin for your application, in which case you could explicitly load the dll […]
