If you are going to create a project in ATL or some other type, then MFC is often included.  The reason for this is often for a few collection classes and CString.  There will be some overhead in an ATL project if MFC is included and the collection classes is not that hard to rewrite. […]

What’s It All About? This article is an introduction to STL-style iterators, and how by writing your own iterators, the use of certain containers can be simplified and made STL compatible. The containers used in this example are the MFC framework application, document template, and document classes (CWinApp, CDocTemplate, and CDocument), which form a hierarchy […]

In some applications, maintaining a separate MRU list for each document type is needed. This article describes how to do it and includes a sample project. Basically, what I did was to transfer all the MRU functionality from the application class to the document template. The files DocTemplateEx.h and DocTemplateEx.cpp contain the declaration and implementation […]

This function will merge two menues. This can be used for context menus as well as for top level menus. At top level known popup menus will be appended or new popups will be created before or (currently untested). The function calles itself recursivley and does not care about consecutive seperators. void MergeMenu( […]

A lot of people have been asking questions about printing a simple straight multi-page text buffer to a user-selected printer, without using the docView framework. You could use the classes created by Richard Stringer, but quite often, this is a big overkill for what you want to do. A few suggestions have been made and […]

This article was contributed by Pierre Fournier . For my project, I needed to load PCX files and couldn’t find the source code to do it.   I took a documentation about the file format of PCX files and decided to give it a shot.  The effort was worth it!  If you would like to […]

IBM and Dragon have made quite a splash with their voice software enabling users to dictate text to their computers and use voice to control applications. This article presents an MFC class based on the Microsoft Speech SDK which will enable you to make your application work with these engines to accept voice commands. To […]

of . Environment: Unicode, MBCS In order to allow your programs to be used in international markets it is worth making your application Unicode or MBCS aware. The Unicode character set is a "wide character" (2 bytes per character) set that contains every character available in every language, including all technical symbols and special publishing […]

I really love using macros in VC++. They make things highly customizable, like I like them. Not how MS wants me to use it. So, I took the liberty to add to Thomas Mahler’s wonderful macro for increasing build number. I added support for increasing ALL the build numbers avaliable in the .rc file. I […]

other mail Hubert Coupez I also use Visual source safe for more than two years so I wrote a file header macro creator. This macro inserts Visual SourceSafe’s keyword expansion depending of information found in the file. This macro checks for : class Interface class Implementation class Type library The Macro checks for more than […]

Environment: Visual C++ 6.0 I wrote some classes that download ftp files with a status dialog. My classes use the internet service classes included in MFC CInternetSession, CFtpConnection, and CFileFind. The downloading is done in a seperate thread so that the cancel button can cancel a download operation. I want to mention two things up […]
