Macro that creates a .h / .cpp file pair. It will prompt for a file name and create the .h / .cpp files accordingly. The .h file will be given a small header and the usual #ifndef _FILE_H … sentry. The .cpp file will be given an #include “MyHFile.h”. The technique behind this code generation […]

The CColor class emerged from the need to manipulate color in the HLS modell, this means to directly change attributes like luminance or saturation. The HLS modell makes it very easy, to draw such things as color gradients between any color, too. Perhaps NT 5.0 will support the HLS (or the similary HSB) color modell, […]

In this article, I demonstrate several topics related to Word automation in MFC : How to run Word 97 using automation from an MFC client using the #import compiler directive. How to use the wrapper functions generated by #import to simply add a new document and make Word visible to the user. How to catch […]

In certain situations, there may be a need to programmatically register or unregister a COM server given just the name of the module that actually implements it. The specified server could be an InProcess COM server or an OutOfProcess COM server. As we all know, inprocess COM servers are registered by loading the DLL module […]

Environment: VC6.0 Visual C++ v6.0 is shipped with a very good integrated debugger, but it has even more features then is documented in the online help files. I’ll briefly describe some of these features, so you can use them to make your own programming a little more efficient. Some of these tips were mentioned during […]

Attempting to monitor the serial port can be a frustrating experience. Without buying expensive shrink wrapped software, there’s really nothing available. That was my motivation for creating an MFC program called COMMSPY. COMMSPY is a dialog based, serial port monitor for Windows.  It is a Windows GUI built around the ever popular Visual C++ SDK […]

Resources Explorer was written by me after I’ve spent too much time (as I thought) trying to find some resources I wanted to use in my app. It was an AVI usually shown when you delete some file. So due to my previously written programm (which shows the modules other application uses while running) and […]

Changing the tool tip as the mouse pointer moves along different tree control items is fairly simple. The tree control can be on a dialog, property page or a form view. Assuming that you use a class derived from CFormView called CMyFormView, which has a tree control, the steps to follow are: Declare a member […]

There may be occasions when you inherit a project that does not have the typelibrary compiled as a resource into the module that implements your COM object (be it a COM server, ActiveX etc.). In such a situation, a lot of people are left wondering how to make the typelibrary part of the module’s resource […]

Introduction Did you cheer when you found out that ATL 3.0 would support ActiveX control hosting? I did. This functionality was at the top of my wish list for ATL. ATL 3.0 has finally arrived. What now? In one news group, I saw the following question: "How do I resize ActiveX controls hosted by Composite […]

The singleton pattern given in the book "Design Patterns" [1] has the problem that the memory allocated on the heap is not freed anywhere which results in a memory leak. The C++ class given below is one way of implementing the singleton pattern without a leak. The class given, however, does not address such issues […]
