WPF: Change the culture when application runs.

[=?Utf-8?B?RW1pbA==?=]

Hi all,

I’m very very new in C#/WPF world, but this fascinates me more and more. Now
I must find a way how our future application will use the localization /
globalization. I did all the steps I found in MSDN to create this (UID,
LocBaml, satellite, etc.) and I it works perfect (a little bit complicated
but anyway it works). The application starts in the OS culture starts, also
if I put at the beginning this code:
public App()
{
Thread.CurrentThread.CurrentUICulture = new CultureInfo("de-DE");
//Thread.CurrentThread.CurrentUICulture = new
CultureInfo("en-US");
}
It works perfect.
Now I try (and I spent too much time for this issue) to change the culture
online, when the application runs. Something like:
private void CheckLanguage(object sender, RoutedEventArgs e)
{
Thread.CurrentThread.CurrentUICulture = new CultureInfo((german)
? "de-DE" : "en-US", true);
}
When the user clicks a button to change from german to English. I guess I’m
too naive to believe that, but I don’t know what should I write so to get my
current main window show all stuff in other language?
For any idea thank you in advance!

Best regards,
Emanuil
