One of the restaurants that opened at the new Microsoft Commons is Spitfire, which opened under its own name instead of one of the many wonderful alternatives proposed. At The Commons, the dining establishments operate in a variety of ways (cafeteria, buffet, fast casual, deli, etc.) but they share the common characteristic that you pay for ...

Commenter sarathc asks, "How do we implement a custom scroll bar as Windows does? What is the logic behind the thumb size and position calculation? How we could dynamically manage it?" Let's look at the three questions in turn. To implement a custom scroll bar... don't do it. It's just not worth the effort, and there will almost always be ...

A few years ago, Larry Osterman explained the famous beeping death. Windows 95 had its own noise-related death, what nobody has called ticking death, but that's what I'm going to call it. (Let's see how long before somebody decide to add it to Wikipedia.) When your machine fell into ticking death, each time you moved the mouse or ...

Commenter Dave jokingly remarked, "I've grown used to handling characters with ASCII. (If it was good enough to represent every character in the US Constitution, it's good enough for me.)" But there's a double-joke in there. You see, not every character in the United States Constitution can be represented in ASCII! If you take a close look...

Why does the Start menu search box autoselect some items but not others?

When you open the Start menu and type into the search box, sometimes the first search result is autoselected (so you just have to hit Enter), whereas sometimes See more results is autoselected. Is there a method to this madness? If an item is found in the Programs and Control Panel sections, then the first such is autoselected. Otherwise, ...

I spent the other night at a relative's house, and I was woken the next morning by my young niece who politely asked me to make her breakfast. (Her technique for waking me up is to come in and call my name. If the door is closed, she pounds on the bedroom door and shouts, "Wake up! Wake up!" If I fail to open the door, she opens it herself. If...

Adrian McCarthy asks, "Can you create an information context for the display? ... I can call CreateDC("DISPLAY"), but perhaps that wouldn't generalize for a multiple-monitor display with different settings on each screen. I'm trying to avoid constantly creating and destroying DCs when all I need to do is measure strings, check color depth, dpi...
