I see variations on this question occasionally. "Why is my low priority thread consuming 100% CPU?" Setting a thread to low priority doesn't mean that it won't consume lots of CPU. It just means that it doesn't get to run as long as there is a higher-priority thread ready to run. But if there is a CPU looking for something to do, and there is no h...

Specifying whether elevation is required is typically something that is the responsibility of the program. This is done by adding a element to your manifest. (Bart De Smet shows you how. Calvin Hsia does the same for your Visual FoxPro programs.) But if the program you're running doesn't have such a manifest—maybe it's an old program that...

I have no idea why the window manager team added this feature to Windows NT. It basically says, "Hi, use this key to violate all the rules known to mankind about what can legitimately be done in a function. Oh, and be an attractive malware attack vector, too." I've debugged a few crashes that were traced back to the key. What makes them p...

Here's a question that came in from a customer: Is there a way to view all the Windows color schemes at once? We want to display text in the color against a background of , and we want to check that this looks good in all of the themes. A mistake I see from some programs is mixing system colors that are not meant to be mixed. The colors I'm tal...

Hotkeys involving the Windows logo key are reserved by the system. New ones are added over time. For example, Windows 98 added Win+D to show the desktop. Windows 2000 added Win+U to call up the Utility Manager. Windows XP added Win+B to move keyboard focus to the taskbar notification area. And a whole bunch of new hotkeys w...

You can use the message with the flag to indicate that the message number you passed is an error code and that the message should be looked up in the system message table. This is a specific case of the more general case where you are not in control of the message, and when you are not in control of the message, you had better pass the flag. ...

The function is another one in the category of functions that everybody tries to pretend doesn't exist. It's not as bad as , but it's still pretty awful. The idea behind the function is that you have a frame window with a bunch of optional gadgets, such as a status bar or toolbar. The important thing is that these optional gadgets all reside at...

Commenter praful asks what to me is a rather confused question, but I'll try to guess what the real question is. If you drag My Computer to the Start button in XP, you get an expanding menu that lets you see all files and folders as submenus. Is this menu available to applications via an API, or do you have to build it yourself? For example, c...

Apparently some people think my psychic powers extend to being able to steal trade secrets by sheer force of concentration. I've been trying to write an application which allows to drag and drop documents from lotus notes. If I just drag and drop a document from lotus notes to Windows explorer, it creates a .shb file (regular windows document li...

A customer who is writing some sort of code library wants to know how they should implement a function that determines whether a file exists. The usual way of doing this is by calling , but what they've found is that sometimes will report that a file exists, but when they get around to accessing the file, they get the error . The lesser questi...
