. This article replaces my former article "Dynamic child window positioning" (cdxCDynamicControlsManager). See the what’s new section to find our whether it’s worth changing your code. What’s this article about ? I’ll introduce you to some of my code that has will make your windows support automatic repositioning of their child controls. I’ll call such […]

Environment: Windows NT 4 SP6, Visual C++ 6 SP3 For a while, I’ve wished for tool that worked like the csh unix command, where. I.e. a tool to display where an executable is found in the search path. Finally, I wrapped the SearchPath API call in a command-line where utility. I added a couple of […]

Environment: Windows NT4 SP5, Visual C++ 6 SP3 Have you ever made sizing dialog boxes? Well I’ve made some (with my bare hands and a bit MFC support). Well it was quite a hack. Later on, I’ve found some code on CodeGuru that made the whole thing much easier, but I didn’t like the approach: Deriving […]

Web site This code in large borrowed from an article and code sample by Steve Zimmerman "Create Apps That Are Easily Extensible with Our Smart "Snap-Ins" Methodology".   Its been updated to work with ATL 3.0 and VC 6.0, plus a few extra modifications and demonstartions of the coolest technologies :). To see this sample code […]

Environment: Windows NT4 SP5, Visual C++ 6 SP2 Introduction Sometimes you might wish you could use other icons in a message box apart from the ones Windows gives you, or you might want to have more control over how your message box, specify which language to use, etc. Well, there is a way to do […]

Click here to enlarge image Environment: Windows This is the simplest of utilities intended to make UI testing easier by allowing you to change the system colors (as specified in the documentation for GetSysColor) with the click of a button. Simply run the executable and then click on the Tray icon, select the system color […]

Environment: Windows 2000 RC2, Windows NT4 SP6, Visual C++ 6 SP3 Dynamic Dialog class These classes are being used for displaying a modal dialog, on which the controls are dynamically added, without the need of having a dialog template as resource. These classes were developed as base classes for use in a script parser, where […]

Environment: Windows NT4 SP6, Visual C++ 6 SP3 Having a property sheet inside a property page causes some problems: Child CPropertySheet hangs if focus is switched (Q149501). Parent property sheet terminates even if a child page has a Data Exchange failure. OK, Cancel, and QuerySibling messages are not transferred to child sheets. Child sheet has […]

Environment: VC6, NT4 SP4, These three classes are my attempt at recreating the standard buttons on the Macintosh. The normal appearance of the buttons duplicates the 3D look of the more recent MacOS versions, but an old-style “flat” look can also be used by setting the button’s Flat style in the resource editor. The following […]

Environment: Windows NT 4.0 SP5, VC 6 SP3 This is the second in a series of (probably four) articles on context menu extensions. Despite the GUI orientation of Windows programs, it is sometimes necessary to pass command line parameters to a program. The most prominent example of this in my experience has been ATL services: […]

Environment: Windows 95, Visual C++ 6 We had a need for users to not tie up file sharing licenses all day when not needed. Since they only needed the network drive mounted for one app, I embedded routines in the app to automatically check for the drive non-existence, prompt for password, and mount the drive. […]

Environment: Visual C++ 5 Why this code? Suppose you have a number or controls on various windows that you want to drag and drop data between. Now suppose that the data shown in your controls come from your own data objects, so that dragging and dropping is not only required for text by also your […]
