At LvS (the opensource application of LeViS), I’ve been using this (VB.net) code to set the UI language (for example to Greek): Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("el") Others seem to have been using (C# – that’s why there is a trailing semicolon): Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("el"); assuming System.Globalization and System.Threading namespaces have been imported. However, now that I’m [...]

I’ve managed to combine http://www.codeproject.com/Articles/85603/A-WPF-custom-control-for-zooming-and-panning and a cut-down version of it for Silverlight that was out there: http://www.codeproject.com/Articles/167453/A-Silverlight-custom-control-for-zooming-and-panni I did it in a way that the Silverlight version is source-code compatible with the WPF version (via a WPF compatibility layer that even implements value coercion), so that both the WPF and the Silverlight projects share [...]

System.IO.IsolatedStorageSettings doesn’t exist in WPF (only in Silverlight) but can easily be ported from Mono project’s Moonlight implementation (the Moonlight project home is at http://www.mono-project.com/Moonlight), as suggested at: http://groups.google.com/group/wpf-disciples/browse_thread/thread/4ed6c009f3fb7d69 I found that implementation at the following URL: http://vega.frugalware.org/tmpgit/moon/class/System.Windows/System.IO.IsolatedStorage/IsolatedStorageSettings.cs Did some modifications to IsolatedStorageSettings.cs to make it work with WPF (whether the application is deployed via [...]

Copying here my answer at: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/11a42336-8d87-4656-91a3-275413d3cc19 What seems to work for me is the following (copying from the source code of http://ClipFlair.codeplex.com [currently under development]) note I’m using Build Action = "Page" and Custom Tool="MSBuild:Compile" at the properties of Themes\DropDownTheme.xml and Themes\RotateHorizontalTheme.xaml, as was for Themes\Generic.xaml. Seems to work OK (probably this is faster at [...]

Just came across http://wangmo.wordpress.com/2007/09/27/themesgenericxaml/ which gave me a hint on why a WPF control wasn’t getting instantiated correctly when loaded from an external assembly (dll): to load generic.xaml for WPF, at the start of Properties\AssemblyInfo.cs you need (note this isn’t used/needed in Silverlight): using System.Windows; and at the end of Properties\AssemblyInfo.cs you need: [assembly: ThemeInfo( [...]

To sum up the discussion at http://stackoverflow.com/questions/1360113/is-java-regex-thread-safe/, you can reuse (keep in static variables) the compiled Pattern(s) and tell them to give you new Matchers when needed to validate those regex pattens against some string: import java.util.regex.Matcher; import java.util.regex.Pattern; /** * Validation helpers */ public final class Validators { private static final String EMAIL_PATTERN = [...]
