Environment: VC6 I had to make a project last month for the Compiler Techniques course at the university where I study.  This project was to make a simple Pascal compiler for an imaginary virtual machine.  I also work for a software company so I had to make the project in my free time after university […]

Environment: VC5, NT4 SP3 CRichEditCtrlEx is derived from CRichEditCtrl and contains two methods for create the control. The background of a rich control could be changed using SetBackgroundColor() method. When the display has 256 colors the RGB value from SetBackgroundColor() method is converted into an apropiate color from system palette. So I created a pattern […]

Have you ever wanted the CCombobox class to display "readable" text when it is disabled? No matter whether it is a drop-down or a drop-list type of combobox! Here’s a class that’ll do that (and much more, although the rest is not visually related)! For example, in the pictures below, you can see the "before" […]

This article was contributed by Tom Archer and Rick Leinecker. Preface This class is meant as a very simple alternative to the more robust, feature-rich CSerialPort class presented by Remon Spekreijse. In other words, if you need a very simple class to read or write data to the serial port, then this class might be […]

Environment: VC6 SP2, NT4, 9x During some long data processing, it is useful to let the user know that "something is happening, honest!" Many programs (such as Outlook Express) do this by the neat trick of showing an animation within one of the status bar panes. This article shows how this can be achieved by […]

The method CreateDragImage is used during drag’n drop to create a drag image. The problem is that it only works for a CTreeCtrl with images. The following method, CreateDragImageEx, checks whether the CTreeCtrl has a valid normal CImageList. If so, it just calls the standard CreateDragImage method and returns. If, on the other hand, no […]

[This assumes the user has installed the necessary DAO files, included on the Visual C++ CD, and that you are using VC++ version 5.0 or later] Overview: Occasionally on the discussion board there are requests for examples of how to access database information. One common method is a dialog-based retrieval of data from a record, […]

Environment: Visual C++ 6, IE 5 This example program and code show you one of the ways to use the new, mostly undocumented, FilterBar feature of the ListView control that is available with IE5.0 (or greater). While the example application works, it is by no means an optimal example of how to use this new […]
