Here is an explanation how to implement WYSIWYG text output: First of all, […]

Environment: Visual Studio .NET, managed C++, C#, Visual Basic In one of the applications I have created is a “Send To” menu class using MFC, which displays a list of the user’s “Send To” extensions and sends a file to the extension the user selects.

Environment:VC++6.0 and later Introduction The sample has no executable, so the source would have to be compiled; VC++6.0 automatically registers the control. Below is a list and description of the interfaces and how they may be utilized. The ruler itself consists of one CWnd derived class, CScale. The implementation is about 2000 lines of code, […]

Introduction This article discusses why ATL uses template classes. This is not a discussion of ATL features, but just the principle behind the Template library. Let us start with an implementation of the IUnknown interface. We all know that this is an interface that has to be supported by all COM objects. So, I thought […]

Environment: VC++ 6.0 SP4, Win95/98/NT/Me/2K/XP Introduction One of the many aggravations of Visual Studio is the inflexibility in changing the source code control (SCC) provider. After researching the problem, I found that all SCC provider information is stored in the Registry under HKEY_LOCAL_MACHINE\SOFTWARE\SourceCodeControlProvider. If you open the Registry and go to this key location, you […]

Using Unsafe Code in C# to converting color-keyed bitmaps to custom regions. .

Fortunately, we can change the appearance of our buttons by overriding the DrawItem function of the CButton class. I ‘m going to demonstrate the steps of the owner drawing button. In this article, I will make […]

The subject of this article relates to strongly typed collections, ADO.NET, and XML serialization. Earlier this month I demonstrated how to create a strongly typed collection (see “Implementing Strongly Typed Collection”). A strongly typed collection is a collection that contains a known type of object rather than a generic reference to the object class. Strong […]

. Environment: VC++, DDK Introduction Deleting files can be both a heaven and a hell. Heaven is when you really need some files deleted to gather some extra space or to clean up the system’s disks and you delete them. Hell is when files get deleted because of unforseen instances, such as virus activity. Some […]

Environment: Visual C++ This copy protection scheme first requires you to detect bad sectors in the floppy disks. Then, four of the bad sectors are selected. Pressing the copy protect button will write a secret data file to the floppy disk that is the key disk. Then, to use the copy-protected floppy disk, you have […]

Environment: VC6, MFC, Win95/98/NT/2000/XP Introduction You can always get the font name of one of your installed fonts. But what if the font is still not installed in the system and you want to know its name programmatically? Of course, you can temporarily add it to your system fonts and get its properties then (hmm… […]
