This isn't psychic debugging, but it's the sort of dumb mistake everybody makes and which you can't see when re-reading your code because your brain shows you what you want to see, not what's really there. I'm trying to respond to the notification, but it's not working. What am I doing wrong? You can stare at this code for ages and completel...

Serge Wautier asks, "Why are the copy/cut/paste buttons not disabled when there's nothing to copy/cut/paste?", noting that the back/forward buttons do disable themselves when navigation is not possible in that direction. To get to this question, we'll first go back in time a bit to a world without toolbars. In those early days, these dynamic optio...

The documentation for the parameter for the function covers the issue, but since people seem to really like charts and tables, I'll present the same information in tabular form.

I often see people write code that goes something like this: The intent here was to perform the operation on all the windows in a window tree by operating on the root, then operating on each of the children. Operating on the children is in turn performed recursively, so that we eventually see every window in the tree. Except that if you actua...

For some reason, people are really puzzled by rich edit printing. I'm no expert on printing, but even I was able to figure it out. The kernel is the message. Each time you call it, a little bit more of the rich text control is printed, and the message returns the index of the first unprinted character, which you can pass back in to print the next...

Last time we looked at loading an entire file into a rich text control. The code runs great, until you try to use it to display a license agreement provided by your legal department, and then some paranoid user reports that they can't read past page seven. (What, somebody reads those things?) What's going on? If you don't specify otherwise, the...

To load an entire file into a rich text control, you can use the message, which accepts an of data all at once. Once you find the message, it's pretty straightforward how to use it, but I'll write out the code anyway; You pretty much follow your nose. The message wants you to tell it the format of the stream () and provide a pointer to an s...

Hierarchical storage management is one of the taxes software developers have to pay. What can you safely do to an offline file? What will trigger its recall? (First, a note on terminology: Recalling a file means to restore it from remote storage to local storage. A file that has been recalled is online; a file that has been placed on remote stora...

Norman Diamond seems to have made a side career of harping on this topic on a fairly regular basis, although he never comes out and says that this is what he's complaining about. He just assumes everybody knows. (This usually leads to confusion, as you can see from the follow-ups.) Back in the ANSI days, terminology was simpler. Windows opera...

Occasionally, I'll see people having trouble trying to for functions like or . Usually, it's coming from people who are trying to write p/invoke signatures, for p/invoke does a under the covers. Why can't you for these functions? Because they're not really functions. They're function-like macros: In fact, as you can see above is doubly a...
