In Windows 2000, Explorer let you add properties like Summary and Author to nearly any file type. But when you view the files from a machine running Windows XP or later, those properties are lost. Where did they go? Most file types do not have extensibility points for adding metadata. For example, every byte of a plain text files is devo...

There are three functions which test very similar things, and sometimes applications pick the wrong one. Here's the rundown: Note that these functions do not answer the question "Is the application using the visual-styles-enabled version of the common controls library?" That question is harder to answer because the decision to use the visual-sty...

is the conventional name for the user-provided entry point in a Win32 program. Just like in 16-bit Windows, where the complicated entry point requirements were converted by language-provided startup code into a call to the the user's function, the language startup code for 32-bit programs also does the work of converting the raw entry point in...

The game PowerPoint-Karaoke was invented in 2006 by Zentrale Ingelligenz Agentur. In this game, contestants are called upon to give a PowerPoint presentation based on a slide deck they have never seen. (The German spelling uses a hyphen between the two words. When "translated" into English, the hyphen is often omitted.) At Microsoft, the term has...

When the window manager was originally designed, it made it possible for programs to override many standard behaviors. They could handle the message so a window can be dragged by grabbing any part of the window, not just the capt...

B: Have you tried an electric bike? C: If you're going to eliminate pedaling, then you may as well g...

I covered the function in my 2008 PDC presentation, but one thing I didn't mention is that the buffered paint functions are very handy even if you have no intention of painting. Since the buffered paint functions maintain a cache (provided that you remembed to call ), you can use to get a temporary bitmap even if you have no intention of actu...

Looks like that's what the Microsoft C runtime uses for an abort.

I am watching the continuing battle between Facebook and Facebook spammers with detached amusement. When I see a spam link posted to a friend's Facebook wall, I like to go and figure out how they got fooled. Internet Explorer's InPrivate Browsing comes in handy here, because I can switch to InPrivate mode before visiting the site, so that the site ...

We saw some time ago that taskbar notification balloons don't penalize you for being away from the computer. But how long does the balloon stay up when the user is there? Originally, the balloon appeared for whatever amount of time the application specified in the member of the structure, subject to a system-imposed minimum of 10 seconds and ...
