I don’t know how “cool” this class is — it’s not really innovation as much as hard work — but I have found it extremely useful.  I have seen attempts at this in the past that I never really liked very much… Basically, I love the ease of use of MFC’s CString class but I […]

Environment: VC6 SP3, NT4 SP5, Windows 98, MSIE 5.0 This application was implemented for exercise purposes only. However I hope that ideas enclosed in it can be useful since it is sometimes required to get a Common Dialog modeless. Each Common File Dialog window has its style changed during creation and then lives in its […]

Recently I had to create a proprietary communication protocol stack to provide a link to custom hardware. During this task Ive encoutered a problem. I needed a timer. Windows provides you timers through SetTimer() function or through CWnd::SetTimer() function. In both cases, your class must be a window to use the timer. I did not […]

The following classes, CRecordSound and CPlaySound, record sound and play PCM sound simultaneously. An example dialog-based program is provided that records, saves to disk, and then echos sound. This example also contains two more classes, CWriteSoundFile and CPlayMMSound. CWriteSoundFile receives sound buffers from CRecordSound and writes them to a WAV disk file. CPlayMMSound opens these […]

. The inspiration to write this code was to have an easy-to-use parser for functions given as string. You have a string like “cos(x)-7*x/(1+x)” and you want to compute some values, maybe for displaying the graph of the function. You can write code like this: CFunction* fkt = CFunction::Parse(“cos(x)-7*x/(1+x)”); long double y = […]

To add a customized windows dialog to the windows menu, you just have to take only two following steps in the mainframe class… Override InitPopupMenu and replace it with the following code : #define DEFAULT_NUMBER_OF_MDIS 9 void CMainFrame::OnInitMenuPopup(CMenu* pPopupMenu, UINT nIndex, BOOL bSysMenu ) { CMDIFrameWnd::OnInitMenuPopup(pPopupMenu, nIndex, bSysMenu); // If the number of active windows […]

at Definitive Solutions, Inc. Click here to enlarge image Environment: Windows NT4 SP5, Visual C++ 5 This is a very simple (but easily enhanced) CStatic-derived class to do bar, line, and pie graphs. Why create one of these instead of just using the Microsoft-supplied control? Mostly because I want better control over the appearance. The […]

This article includes an updated SYSEX exception class. I would like to thank Dale Nagata for testing out the earlier version with an in-process server (something I had not done) and for pointing some nasty problems. The updated version includes fixes to these as well as some other enhancements. The updated version now propagates error […]

Many new MFC programmers wonder how to ‘replace’ the default icon rather than to change or edit in the resourc editor. Here are two simple ways to do this (actually one method but two versions). 1. There is an ICON statement in the resource (.rc) file that causes the resource compiler to include the icon […]
