In many cases, the programmer needs to understand what a value means. It’s about window styles. For him 0x500000C2 means nothing as window styles. Of course, Spy++ solve this problem, but you must lookup for a window with that styles. It’s easy, to drag a cursor over the window, and then windows style can be […]

What it is: This Grid Control (CGridCtrl) allows you to display a 2-Dimensional grid with check marks in it. It can be used to show associations of the two columns. For example the Screen Shot is a grid of NFL football teams. Each check mark represents a game which will be played. In the example […]

NOTE: You must also have the new COMCTL32.DLL (version 4.7 or later). This is installed with Internet Explorer 3 and will come standard with the new Windows 98. So if you are using VC++ 5 then you probably already have this DLL. The API support is available in VC++ 5.0. Otherwise, you need to download […]

The original program and article was written by Shekar Narayanan. It allowed for the month and the date to be selected. In the updated version, the date, month and year can be selected (from the year 1583 onwards; yes it is Year 2000 compliant!!). What is this? This is a custom control which allows you […]

Download demo project. The Calendar Control 8.0 (mscal.ocx) shipping with Visual Studio 5.0 looks very nice. It can be very simple incorporate in your application as a date picker control. It has two combo box to quickly change a month and a year. Unfortunetly, when you try to change the month or the year the […]

Download Source Code and Example The idea is for drawing the button and pop-up window is taken from Chris Maunder‘s contributions! What is this? This is a custom control which allows you to select a month and year from a drop down window. This custom control actually consists of two classes – one derived from […]

I just read the article “Use the Date/Time Picker common control (IE3+)” and now I’ll try to explain my code. I want to use only MFC interface for all my applications,then when MFC doesn’t wrap some API and I want to use it,I write a MFC class. In the article I just read,I see a […]

Download Source and Demo project: avl.zip I have implemented the binary tree’s of Addison-Velski and Landis (AVL-Tree’s), which allow Standard-operation like Insert, Search and Delete in logarithmical time. Ordinary binary trees can become very obscure. They can become a linear structure and the basic operations take linear and not logarithmical time. The advantage of the […]

This WaveFile manipulation control provides a  basic interface for displaying and editing wave files within a commercial audio-processing application. The app contains code on displaying the graphical data, using button logic and rudimentary mouse input to manipulate the waveform data. Thanks go to Ken C. Len’s Histogram Control for providing much of the underlying control code. […]

Intro MFC implements a convenient feature called a most recently used list, or MRU. In SDI and MDI apps generated by AppWizard, the MRU list appears on the File menu. However, another handy place where MRUs are used is in comboboxes. For example, the Start/Run dialog lists the last few programs that you’ve run in […]

StackUp is an old logical 2D game. First I saw it on C-64 and  I very enjoyed it (2D games are my favourites). I programmed it on Amiga (assembler / hardware chipsets addressing) few years ago. I think that C++ / DirectX / MFC is one of the easiest and fastest ways to do this […]

Occasionally, your program may need more low-level information about the computer it’s running on than is readily available with MFC. Usually, this can be solved by a simple API call, which, with a small amount of practice and patience, can become as easy to deal with as MFC. This appears to be the case with […]
