Are unused CSS images downloaded?
- by Alex
Are unused CSS images downloaded by the browser or ignored?
Eg. in CSS rules which don't match any elements.
.nothingHasThisClass{background:url(hugefile.png);}
Or would this be browser-dependant?

Need a scenario where would fail Array.ConstrainedCopy()
- by Sir Psycho
Hi, Just playing around with some of the APIs in .NET and I can't seem to find a way to cause Array.ConstrainedCopy() fail. According to MSDN, it's treated as an atomic operation. If it fails during the copy, the entire call fails resulting in no elements being copied as opposed to its Array.Copy() counterpart. Can someone demonstrate this or tell me how to do this?Read the article

What's the best way to display a blown-up image using minimal JQuery?
- by TkTech
The Goal: On mouseover (or :hover), enlarge the preview image by about 400% and display it in the center of the page Remove the preview when the mouse leaves The Problem: Solutions like FancyBox are too bloated in FancyBox's case it ignores width and height for image elements, which makes it useless Most of these "lightboxes" steal focus when they're called Really, I'm just looking for a simple, efficient solution.

Combobox seems to reload itself
- by developer
Hi, I have a combo box drop down for fonts in one of the apps. Now when I click on the dropdown to see the available list of fonts, I see a flickering effect. It seems as if the combo box keeps on reloading itself or getting refreshed. Is it because it covers some of the other UI elements like textboxes when I click to expand the list, or is it some kind of known bug with WPF? Is there a workaround for this?Read the article
