About once every two months for the past six months (I stopped checking further back), somebody reports a problem with the function. Often, they don't include very much information at all. They just say, "I call the function and it doesn't work." Here's an example: I'm hitting a problem with when using it to frob files in the gonzo directory ...

In the suggestion box, A. Skrobov asks why it's impossible to superclass , but the example that follows is not actually superclassing. When I register my own class under this atom, and leave NULL in WNDCLASS.hInstance, Windows fills it in for me. Then I have two distinct classes registered: (0,WC_DIALOG) and (hMyInstance,WC_DIALOG), and DialogB...

Functions like and , when asked to provide information about a symbolic link, returns information about the link itself and not the link destination. If you use the function, you can tell that you have a symbolic link because the file attributes will have the flag set, and the member will contain the special value . Okay, great, so now I know ...

A customer was having trouble adding Windows 7 taskbar integration features to their application: I'm trying to use the new Windows 7 taskbar integration features, but am running into a problem. I've made certain that my program has the and [corrected 8am] attributes set, yet I never receive a message in my window procedure. A me...

For some time (I am too lazy to look up when it was introduced), the Visual Studio linker has supported a feature known as delay-loading. But why can't you use this feature to delay-load a function from ? It would be very handy: If you write the program fails to load on versions of Windows which do not support the function because the Win32 ...

A customer asked, Is there a way to turn off Full Window Drag on a single window? I have a resizable control that I would like not update itself while resizing. It so happens that I wrote a sample program ages ago to illustrate how to do this. You can find it in the Platform SDK under . The source code is also reproduced in this Knowledge ...

There seemed to be a great deal of disbelief that anybody would hard-code the path to Notepad. Here's one example and here's another. There's a large class of problems that go like this: I'm running Program X, and when I tell it to view the error log, I get this error message: What is wrong and how do I fix it? Obviously, the file is ...

You may hear an old-timer developer use the verb zap. That proposed fix will work. Until everybody gets the fix, they can just zap the assert. The verb to zap means to replace a breakpoint instruction with an appropriate number of NOP instructions (effectively ignoring it). The name comes from the old Windows 2.x kernel debugger. (Actually, ...

Jonathan Wilson asks why the clipboard APIs still require GlobalAlloc and friends. Why is there not a or something that does what does but without needing to call ? Okay, here's your function: Whoop-dee-doo. Historically, Windows doesn't go out of its way to include functions like this because you can easily write them yourself, or you ...

It turns out that my quick overview of how processes exit on Windows XP was already out of date when I wrote it. Mind you, the information is still accurate for Windows XP (as far as I know), but the rules changed in Windows Vista. What about critical sections? There is no "Uh-oh" return value for critical sections; doesn't have a...
