I am seeing the same behaviour on mod_mono & Apache ,but I can't find where to change the settings.Read the article

Get just the hour of day from DateTime using either 12 or 24 hour format as defined by the current c
- by InvisibleBacon
.Net has the built in ToShortDateString() function for DateTime that uses the CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern format. It returns something like this for en-US: "5:00 pm". For a 24 hour culture such as de-DE it would return "17:00". What I want is a way to just return just the hour (So "5 pm" and "17" in the cases above) that works with every culture. What's the best/cleanest way to do this? Thanks!Read the article

QueryString From Shared Function
- by Kezzer
I'm trying to get a query string from a shared function in a code-behind model using VB.NET. You have to use HttpContext.Current.Request.QueryString("Query") in order to get it from a shared function, however doing HttpContext.Current.Request.QueryString.Count gives back 0, which obviously isn't right in my case as there's many that exist. Is there some sort of issue with using this static call from a shared function?Read the article

Keeping an application on top and in focus - always
