I’ve heard several misconceptions about the use of CStrings and thought it would be beneficial to some of you to clear these up. In this document I will describe how CString works and address 3 key misconceptions: Passing CString by value is bad Using CString causes memory fragmentation CString is slow Inside CString The CString […]

Environment: ****** –> In the MFC architecture CDialogBar can provide more flexible ways to create a control bar in the application than traditional toolbars using CToolBar. Apart from standard button like controls of toolbar, a dialog bar can include other windows controls (such as combobox ) and OCX controls as well. They also provide very […]

Environment: ****** –> Default system menu for standard MFC toolbar has maximize/minimize/restore ability. I didn’t like the way the Maximized toolbar looked. Ben Summers and Sushil Saxena already submited some ways to fix MFC bars, however, I found another one: MFC removes SC_SIZE from toolbar frame each time when it appears. BOOL CMiniDockFrameWnd::Create(CWnd* pParent, DWORD […]

These functionality can be achieved by a small modification to the […]

My intention was to create an hyperlink that could be used not only with text but also with icons and bitmaps, and […]

Download source files (5.5K) or Download sample project (30K) This is a simple hyperlink control that can be plugged into any dialog. There are already a few examples of this in circulation (PJ Naughter, and one from Paul DiLascia from MSJ) but none had all the features that I wanted. I have used the “GotoURL” […]

Abstract: The TOutputWnd class was written originally as an IRC-style Output window. By this, I mean a window where the first line that is entered appears at the bottom, and the contents are scrolled upwards, ala mIRC. This is actually alot more difficult than writing text starting at the top of the window. But, forgetting […]

The Header Common Control has a lot of functionality but can still be improved quite a bit. One thing I’ve always missed is to be able to automatically resize it’s columns so that they occupy the entire width of the control. The following class inherits from CHeaderCtrl and adds exactly this feature to the Header […]

If you have ever used a CHeader the first thing you notice that it isn’t as nice as the one that appears at the top of list controls. What I mean by this is that when you resize the control all you get is a resizing line.  When you move this line the header does […]
