You want to use the TAB key to navigate through a non-dialog, so you call in your message loop, but it doesn't work! The problem here is that you are passing the wrong window handle to . The first parameter to is the dialog-like window you want to be able to navigate through. But the code above passes the window that received the message, so...

The takes its stdin and puts it on the clipboard. But how do you get it out? That's today's Little Program. (I guess we could call it .) Okay, what do we have here? We open the clipboard and try to get the Unicode text on it. We then look for the null terminator within the first 0x10000000 bytes. Why do I stop at 256MB? Because I'm lazy and ...

There are two functions that can be used to create one icon that is identical to another. One of them is . The other is . What's the difference? There isn't any difference. Both functions clone an icon. In fact, their implementations are basically line-for-line identical. Originally, there was just one function to clone an icon: . Windows 3...

Last time, we saw how 16-bit Windows converted resources attached to an EXE or DLL file (which I called module resources for lack of a better term) to user interface resources. As a refresher: During the conversion from 16-bit Windows to 32-bit Windows, some of these rules changed. Specifically, icons, cursors, and accelerator tables are no long...

As we saw last time, in 16-bit Windows, resources attached to an EXE or DLL file (which I called module resources for lack of a better term) were recorded in memory as discardable global memory blocks, and the window manager accessed them directly as needed. For example, if you had an icon or a cursor, the or was really a resource handle, and wh...

Today's Little Program plays a little sound every time the foreground window changes. One of my colleagues wondered if such a program was possible, "so that I stop accidentally typing the second halves of paragraphs into windows that pop up and steal focus." It's not clear whether this program will actually solve the bigger problem, but it was fun...

A customer was adding diagnostics to their application and wanted to know if there was a way to detect that the application was being slow in processing its input. These sorts of delays manifest themselves to the end user as a sluggish application which is slow to respond to input events. They already had a watchdog timer that was reset every time...

Consider this simple function: Depending on your screen resolution and font choices, this may end up displaying like this: That line break was awfully unfortunate, stranding the number 2 on a line by itself. (In publishingspeak, this is known as a orphan.) You can't control where the function will insert line breaks, but you can try to i...

Many functions and interfaces provide the option of passing either a string or an integer. The parameter is formally declared as a string, and if you want to pass an integer, you smuggle the integer inside a pointer by using the macro. For example, the function lets you load an resource specified by integer identifier by passing the identifier in...

Today's Little Program shows a custom source for autocomplete. It's nothing exciting, but at least's it's something you can use as a starting point for your own customizations. We start with a dialog template, whose edit control will be the target of a custom autocomplete. Just for fun, I wrote the program in ATL. Instead of complaining that ...
