You probably know them already, but if you're new to Win32, here are some key window messages. I would normally suggest that you commit them to memory, but if you do enough debugging, you'll end up memorizing them anyway because you see them all the time. I include in the list even though it is a low-traffic message because you do see it a lot w...

There was much speculation as to how the "Ignore other applications that use Dynamic Data Exchange" setting got set. Well, one possibility is that somebody used global state to manage a local problem. "Why on earth does this setting exist?" I don't know, but there appear to be scripts which rely on it. The setting is exposed to scripts, and pe...

Yes, it's an advertisement for Volkswagen, but still, it's a fun video, and it features Scarlatti's keyboard sonata in C (K159) as a bonus. Even the old guy who shuffles along slowly at 1:23 tries the stairs. Double bonus: You can watch the original Swedish version.

This happens to me, too. I once got so distracted by the process of purchasing some tickets in person, choosing the performance date and the seats, fumbling for my credit card, signing the receipt, and when I was done, I left the ticket booth without my tickets! Here is a question that came in from a customer. The details have been changed but t...

I've tried all sorts of miniature headphones, and the only ones that I like are the ones that come with my Zune. What makes them special? They fit and don't fall out. I try not to be too demanding. But the other day, I was getting out of my car, and due to a badly-stowed Zune, the headphones dangled out of my pocket and got caught in the door. Be...

Last time we looked at the classical model for linking as groundwork for answering Adam's question why do we need import libraries? Why can't all the type information be encoded in the export table? At the time the model for DLLs was being developed, the classical model still was the primary means by which linking was performed. Men were men and...

Commenter Adam wonders why we need import libraries anyway. Why can't all the type information be encoded in the export table? This goes back to the classical model for linking. This model existed for decades before Microsoft was even founded, so at least this time you don't have Bill Gates to kick around. (Though I'm sure you'll find a way any...

Whenever somebody reports that the function or the member of the structure is not working, my psychic powers tell me that they failed to manage the double-null-terminated strings. Since string resources take the form of a counted string, they can contain embedded null characters, since the null character is not being used as the string term...

In Hawaiʻi, you see the word Mahalo on signs everywhere. In theory, the word means Thank you, but my friend Joe Beda pointed out that in practice the word has a completely different meaning. Here are some examples: In practice, the word mahalo means You're screwed. Obligatory clarification: This was a joke, an attempt at observational hum...

One of the data formats peculiar to Windows is the double-null-terminated string. If you have a bunch of strings and you want to build one of these elusive double-null-terminated strings out of it, it's no big deal. But what about the edge cases? What if you want to build a double-null-terminated string with no strings? Let's step back and lo...
