As others have reported, it snowed here in the Seattle area yesterday. One whopping inch. You'd think that Seattle, which gets snow a few times a year, wouldn't go completely apoplectic the moment the flakes starts falling from the sky. Especially since it all melts away in a few hours anyway. I didn't watch the local news last night, but I sus...
The function is used to do various things, among them, displaying a balloon tip to the user. As discussed in the documentation for the structure, the uTimeout member specifies how long the balloon should be displayed. But what if the user is not at the computer when you display your balloon? After 30 seconds, the balloon will time out, and the...

What's the deal with those ...ncpy functions anyway?
I try not to rant, but it happens sometimes. This time, I'm ranting on purpose: to complain about macro-izing flow control. No two people use the same macros, and when you see code that uses them you have to go dig through header files to figure out what they do. This is particularly gruesome when you're trying to debug a problem with some cod...
Last week, I saw a performance of Circus Contraption at The Seattle Center with some friends. We were all left agape by the aerialists as they climbed ropes, hoisted, hung, and balanced themselves high above the ground. I thought back to seeing acrobats as a child at the circus and realized how much more impressive they are as you get older and ...
The function releases one thread (or all threads, if manual-reset) which is/are waiting for the pulsed event, then returns the event to the unset state. If no threads happen to be waiting, then the event goes to the unset state without anything happening. And there's the flaw. How do you know whether the thread that you think is waiting on t...

Another type of higher-order enumeration is composition, where one enumerator actually combines the results of multiple enumerators. (Everybody knows about derivation, but composition is another powerful concept in object-oriented programming. We've seen it before when building context menus.) In a producer-driven enumerator, you would implemen...
One type of higher-order enumeration is filtering, where one enumerator takes the output of another enumerator and removes some elements. In a producer-driven enumerator, you would implement filtering by substituting a new callback function that responds to callbacks on behalf of the client for items that should be filtered, and forwarding callb...
