In an old discussion of why the function modifies its command line, commenter Random832 asked, "What if there is no space between the program name and arguments - like "cmd/?" - where does it put the null then?" The function requires a space between the program name and arguments. If you leave out the space, then the arguments are considered ...

A question arrived from a customer (with the rather unhelpful subject line Question for Microsoft) wondering why, when they call and then ask for the states of the various menu items like , the menu item states don't reflect reality. The menu item states don't synchronize with reality until the user actually opens the system menu. There is no req...

A colleague of mine was having trouble getting the metacharacter in a regular expression to work. Of course, when somebody asks a question like that, you first have to establish what their definition of "work" is. Fortunately, he provided some examples: "The last two entries are just sanity checks to make sure I didn't make some stupid mistake l...

A customer reported a problem with their shell extension: We want to format a floating point number according to the user's default locale. We do this by calling to convert the value from floating point to text with a period (U+002E) as the decimal separator, then using to apply the user's preferred grouping character, decimal separator, etc. W...

Since my original article explaining how to get Windows Media Player to single-step a video, I've learned that there's an even easier way. Backward-stepping is dependent upon the codec; some of them will go backward to the previous keyframe. The person who tipped me off to this feature: The developer who implemented it.

Well, of course you can do that. Why shouldn't it let you do that? When multiple monitors were introduced to Windows, video hardware was nowhere near as advanced as it is toda...

Only an idiot would have parameter validation, and only an idiot would not have it. In an attempt to resolve this paradox, commenter Gabe suggested, "When running for your QA department, it should crash immediately; when running for your customer, it should silently keep going." A similar opinion was expressed by commenter Koro and some others. ...

We saw some time ago that you can't simulate keyboard input with . You may get away with it, depending on how the application you're trying to fake out processes input, but since you're just faking data, the application may discover that it's all a ruse when they try to access information that you didn't fake out, say by calling and discovering t...

Some time ago, I noted the increasing luxurification of camping, where people with more money than sense decide to go through the camping experience without building any of the character that comes with it. But that's not the only direction luxurification has moved. Unwilling to accept that "getting there is half the fun", some people take char...
