Environment: Visual C++ 6 You may have noticed that for example CString instaces do not show up as `{…}4 in debug windows (watch, variable, etc. and in tooltip when you move the pointer on a variable). Rather, CString “smartly” shows up as `{“string”}4. This feature can be customized to make your own classes appear smartly […]

Environment: Visual C++ 6 Ever got frustrated with only being able to use 16 colours in the developer studio IDE? A solution to the problem was posted to codeguru recently (in the tips section) that addressed this by hacking the registry, but this required restarting the IDE to update the colours. DevTrueColour is an addin […]

Environment: The code in this article was developed using Visual C++ 4.0 This code is used to make a round dialog for various Apps. This could be good for use with an MP3 or CDPLAYER or any other. Surprisingly it’s not that hard! [I looked but nobody had written anything for a round dialog. I […]

Randy More’s previous article (posted on March 8, 1998) provided a solution to solve the problem of using one extension dll in another. Basically, he suggested that we redefine the macro AFX_EXT_CLASS in one dll’s header file before including a header file for classes exported by a second dll , and restore the previous macro […]

Environment: The source is UNICODE compliant and was tested with both Visual C++ 5 SP3 and Visual C++ 6 SP2. The demo is a Visual C++ 6 project. In a few of my projects I have to deal with processes. To protect me from implementing all of the hard bits again and again, I developed […]

The main module and sub-modules commonly are Document-View window frame. This design is similar to COM mechanism, but directly and simply use DLL to realize the sub-module. The method to put Document-View child […]

Last week I had to create a toolbar on a dialog. I have never done this before and I was in too much of a hurry to want to figure it all out for myself. I turned to the code guru for help. I did find a lot of good information, but what I really […]

Shown here is the application that generates CObject and CObList derived classes for Object-Oriented database management. Some of the projects I have been working on lately have made extensive use of CObject derived classes for encapulated data management (Object-Oriented Databases). After creating only a few data objects, you begin to realize that the production of […]

I think it is fairly self explaining. I have added calls to put and get numerical entries into the string class by Zafir Anjum. This, with the parsing routines already included, have proven quite usefull at least to me. The following extentions add numerical reading and writting to the CStringEx Class. The default field length […]
