The following function ensures that a column is at least partially visible. Rex Myer provided a comparable function in his article “Multiline editable subitems”, but his code relies on the list having an item with index 0, it steps through all columns to find the left border and finally, if a column overlaps the right […]

I wanted to add the title-tip class to the new version of the CListCtrl in Visual C++ 6.0. However, as has previously been pointed out on this site, the code doesn’t quite work for a List Control with the LVS_EX_HEADERDRAGDROP style enabled. The code fix previously posted is more complicated than neccessary with the new […]

. Lot of you may recognize him from the lots of helpful posts on the mfc usenet groups. CDirDialog : this class encapsulates the SHBrowseForFolder API. You can use this class to browse for folders. I had seen many posting asking this question. So, I put together this small wrapper class. In order to use […]

I have extended the CDirDialog class with the following useful features You can specify the parent window of the dialog, so it can act as a modal dialog. You can specify the title of the dialog window The […]

I came across a problem with the VC++ ClassWizard a while ago. If you have a class derived from a standard MFC class, ClassWizard will offer to insert handlers for virtual function overrides. For example, for a class derived from CPropertyPage, you can add handlers for OnWizardNext, OnWizardFinish and so on. However, if you derive […]

 Download Source Code and Example I personally find the Win32 Registry API to be overly complex for performing simple operations. The Win32 Registry API is very "rich". You can do a lot with it, but most of the time you just want to read or write a value. The error checking involved in doing even […]

 Download Source Code and Example To put an icon in the task tray all an application has to do is call Shell_NotifyIcon() to supply the icon, tool tip, callback message and a window to send it to. Making an application that’s just a task tray applet is just a case of creating a hidden window, […]

This menu is another modification of owner draw menus (#2 if you want to know). I have corrected an error I found (use of uninitialized variable in DrawItem), change item measurement (now the height is the bigger from icon height or menu height) and changed the menu concept from using separate icons for each item […]

This simple class gives you a group of three static functions that give you the power to use the clipboard for text. You can now implement cut, copy, and paste in your text-based application with ease, without worrying about the little details of clipboard work. These functions are all static, meaning you don’t need to […]

I’ve always wanted something to do this, but never got around to doing it. Well I found code deep in the mfc that does what i wanted, but i had to cut and paste it cause its not really reusable. Any this is how you use it: CWindowsMessageToString msgConverter; LPSTR lpszMsg = msgConverter.GetStringFromMsg( WM_COMMAND ); […]

For my latest project we needed splitter panes that had proper minimum sizes, in that the user couldn’t physically resize the splitter pane smaller than a specified amount. The standard MFC splitter class allows you to set minimum sizes, but these only affect what is displayed, not how small the panes can be. CMinSplitterWnd is […]

and updated by Michael Martin. Download source files or demo project Adding a CProgressCtrl to the status bar has already been addressed by Brad Mann. His method involved modifying the status bar and messing around with the resource editor. I developed a separate CProgressBar class in order to allow the programmer to just drop in […]
