Back in Windows 95, there was one bug that was originally filed against the window manager team. Upon closer investigation, the window manager team determined that the bug was really in the video driver and added their analysis to the bug as they reassigned it. I don't know what overcame them, but the analysis was written in iambic ...

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 ...

You just have to accept that the file system can change

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 .

I have only one citation, so it may not become proper Microspeak. Too early to tell. Further discussion will definitely generate a lot of good ideas and help drive them for pre-envisioning. Established Microspeak or not, I still don't know what it means...

When you lock memory with it locks the memory into your process's working set. It doesn't mean that the memory will never be paged out. It just means that the memory won't be paged out as long as there is a thread executing in your process, because a process's working set need be present in memory only when the process is actually executing...

Why do we even have the DefWindowProc function?

Raymond Chen
Some time ago, I looked at two ways of reimplementing the dialog procedure (method 1, method 2). Commenter "8" wondered why we have a function at all. Couldn't window procedures have followed the dialog box model, where they simply return to indicate that they want default processing to occur? Then there would be no need to ...

One customer discovered that viewing the properties of a drive from Explorer shows the amount of disk free space significantly lower than the actual amount of free disk space as resported by the disk management snap-in. The command prompt agrees with Explorer and shows the incorrect result. What's going on? Not surprisingly, both Explorer and...
