• Deploy all files in a website or just the ones required to run it?

  - by Haroon

  Hi.. Just wondering is there any drawbacks to publishing a ASP .NET web application by copying all the files in it? (That means all the .cs, .csproj files will be included in the published folder) So far I can think that the published folder's total size may become a little bigger (but that a negligible issue for me).

• 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?

• 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!

• Base32 Decoding

  - by trampster

  I have a base32 string which I need to convert to a byte array. And I'm having trouble finding a conversion method in the .net framework. I can find methods for base64 but not for base32. Convert.FromBase64String – something like this for base32 would be perfect. Is there such a method in the framework or do I have to roll my own?

• Custom description page for the WCF endpoint?

  - by Joannes Vermorel

  I am migrating an ASP.NET Web Service toward WCF. The old Web Service endpoint had a nice extensive description page generated from the comment of the underlying class exposed as a service endpoint. In particular, all available web methods were listed. Is there a way to emulate somehow this behavior with WCF? At least, how can I customize the HTML content of the WCF endpoint?

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