I didn't think this was all that common a request, but it came in twice from two different customers, so I guess there are still people creating toolbars, and creating them with right-aligned buttons (even though it violates Windows user interface guidelines, though I can't find a citation right now). You may have noticed that the toolbar common c...

By default, when you ask to convert a UTF-8 string to UTF-16 that contains illegal sequences (such as overlong sequences), it will try to muddle through as best as it can. If you want it to treat illegal sequences as an error, pass the flag. The MSDN documentation on this subject is, to be honest, kind of hard to follow and even includes a doub...

Commenter doesn't matter proposes a scenario where focus-stealing is necessary: There are two applications A and B, Application B exposes an interface, and Application A connects to application B via that interface, When some sort of even occurs in application B, it notifies application A, which wants to steal fo...

A customer requested assistance with their shell namespace extension, and the request worked its way to me for resolution. The customer was at a loss because the customer's code was nowhere on the stack. What is wrong? The customer didn't provide a dump file or any other information beyond the stack trace. (Hint: When reporting a problem with...

This scenarios is real, but details have been changed to protect the guilty. Consider a window showing the top of a multi-page document. The developers found that when the user clicks the down-arrow button on the scroll bar, the program locks up for 45 seconds, over a dozen threads are created, and then suddenly everything clears up and the wind...

For quite some time, Windows has had a setting officially called active window tracking but which informally goes by the name X-Mouse, because that was the name of the PowerToy which first exposed the feature. (The PowerToy was in turn so-named because it made the mouse behave in a manner similar to many X window managers.) The setting is exposed ...

A customer wanted to prevent users from pinning their application to the taskbar. I have an application that is launched as a helper by a main application. Users shouldn't be launching it directly, but rather should be launching the main application. But since the helper shows up in the taskbar, users may be tempted to right-click on the taskbar...

There are three functions which test very similar things, and sometimes applications pick the wrong one. Here's the rundown: Note that these functions do not answer the question "Is the application using the visual-styles-enabled version of the common controls library?" That question is harder to answer because the decision to use the visual-sty...

is the conventional name for the user-provided entry point in a Win32 program. Just like in 16-bit Windows, where the complicated entry point requirements were converted by language-provided startup code into a call to the the user's function, the language startup code for 32-bit programs also does the work of converting the raw entry point in...

I covered the function in my 2008 PDC presentation, but one thing I didn't mention is that the buffered paint functions are very handy even if you have no intention of painting. Since the buffered paint functions maintain a cache (provided that you remembed to call ), you can use to get a temporary bitmap even if you have no intention of actu...
