Change UI culture programmatically in WinCE 5 / .NET CF 2

Question

In a standard .NET framework application (not CF), I can change the user UI culture with:

System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.CreateSpecificCulture("es-AR");
System.Threading.Thread.CurrentThread.CurrentUICulture = System.Threading.Thread.CurrentThread.CurrentCulture;

but the .NET CF 2 doesn't support CurrentUICulture for CurrentThread.

So far, I found here that maybe the UI culture can be changed by setting

[HKEY_LOCAL_MACHINE\nls\overrides]\LCID
[HKEY_CURRENT_USER\MUI]\CurLang

but it requires rebooting the device after the change. Is there any other way to do it?

TIA, Pablo

Yes, there is. Instead of hacking the registry, use the documented SetUserDefaultUILanguage() API function. From the remarks section of that API:

The new LANGID will not take effect until the device is reset.

Can't get around that. Shouldn't be a problem, users don't change their native language frequently.
