How could it be?

A customer reported a problem showing an icon on their dialog box. We verified that this code does execute during the handling of the message. No assertion fires, yet no icon appears either. Our dialog template says The customer did some helpful preliminary troubleshooting: Verify that the code does indeed execute. It sounds obvio...

Today's Little Program enumerates bit sequences of a particular length subject to the constraint that you cannot have consecutive 0-bits. This may sound kind of arbitrary, but it is important in magnetic media storage, because you cannot go too long without a flux reversal (traditionally represented by a 1); otherwise, the read head's clock start...

Commenter Medinoc was baffled by the statement that the decision to use the visual-styles-enabled version of the common controls library is done on a window-by-window basis. " Isn't it rather on a per-module basis, depending on each module's manifest? If it is indeed on a per-window basis, how does one choose?" Whether a particular call to (or ...

Many people have noticed that the and functions (and therefore their BCL equivalent and WinRT equivalent ) fire multiple events when you save a file in Notepad. Why is that? Because multiple things were modified. Notepad opens the file for writing, writes the new data, calls to truncate any excess data (in case the new file is shorter than t...

Today's Little Program locates the × button in the corner of the window and, just to show that it found it, displays a balloon tip pointing at it. Let's start with the program from last week, the one that displays a balloon tip, then make these changes: Instead of positioning the balloon at the cursor position, we put it at the center ...

Commenter Ivo notes that if you ask to extract an icon at a particular size, the function can return which means "Go jump in a lake do it yourself." But how can you do it yourself? The and functions don't let you specify a custom size, and doesn't work with icon indices (only resource IDs). The function comes to the rescue. This takes all...

Today's Little Program shows a balloon tip at a specific position, then manually removes it. Start with our scratch program and make these changes: When our main window is created, we also create a balloon-style tooltip and add a tracking tool. Normally, the tooltip control appears and disappears automatically, at a position of the tooltip's ...

Simon Cooke dug back into his memory and asked, "Doesn't calling with cause a recreate and re-apply of the styles?" The flag does not recreate anything, but it does reapply the styles, as far as it knows. Recall that the bits in the window style break into two parts. There are the styles managed by the window manager, which are in the upper ...

A corporate customer had a problem with their employees accidentally deleting folders like Videos and Pictures and are looking for a way to restore them, short of blowing away the entire user profile and starting over. They found some techniques on the Internet but they don't always work consistently or completely. What is the recommended way of r...
