Well, this doesn’t really deal with MFC, but its useful knowledge if you don’t know how.. Parts of this code I ripped from VC++ 4.1 help, but it was outdated and didn’t come close to working. First of all you need to add the wave files to the .rc file manually like so: WAVE […]

This is a new an improved version of the Audio Mixer Control Classes. The whole family of classes has undergone a major overhaul since this article was first posted. Bugs have been eliminated, code reuse through inheritance has been improved, one new class was added, and, yes, one class even disappeared! The CMixerSelector class has […]

Introduction Public Interface Overridables Usage Download Comments   Introduction (back to top) This class is a slightly modified “spin off” from the CGTetris application. It is based on a sample in the DirectX sdk (called mstream). The conversion into a C++ class makes it much easier to use. The CMIDI class makes it easy to […]

The reason why I deal with AVI-Files is the following: I have a program that does any (long) calculation, and the output is immediately displayed (a function graph). After each step I can save the current window content as bitmap, and after the calculation I added all the bitmaps to an AVI (using VFD.EXE). But […]

First I ‘d like to write some reason how I come up with this idea, probably that will help future user of this code understand the power and flexibility which these functions provide. Everybody understands the benefits of writing component software and COM comes very handy to help in implementation of components. One of great […]

Line tracker class (KLineTracker) that I present here performs dragging and resizing of lines with left mouse button. It does for lines the same thing CRectTracker does for rectangles. When I needed to add to my application possibility to draw, move and resize lines using mouse, I looked for line tracker class in MFC. Because […]

–> CMappedFile was created after some users complained that my apps were storing too much data in the Registry. I needed a way to preserve the multilevel data heirarchy that the Registry provides, but I needed to do it in external files. In addition, I wanted some protection from curious eyes. CMappedFile is essentially a […]

CRadioGroup: A group box class that handles radio buttons as an array Sometimes when you have a number of radio buttons in a group you don’t want to deal with them individually. CRadioGroup is a simple class that allows you to access any radios bounded by a groupbox as a […]

Object creation is an important step in any Object Oriented Application. An application can use the services of a class only after creating an object of it. In most applications, creating an object of a class is very straight forward, that is, by declaring the instance of the class. For example, to create an object […]

CHHCtrl is an MFC class designed for placing an embedded help window inside of a dialog, property sheet, or window. The CHHCtrl class hosts shdocvw directly rather then using the HtmlHelp API. This bypasses the bugs in embedded help introduced with the version of HTML Help released with Visual Studio 6. It also gives you […]

–>  If you have a dialog-based application, to which you have added a menu, any OnUpdate handlers that you included in the dialog’s message map will never be called.  (Note that the corresponding OnCommand handlers work fine). By handling the dialog’s WM_KICKIDLE message, and mimicking MFC’s routing of its UPDATE_UI messages, you can implement this […]
