I'm trying to localise a simple winform. I've succeeded in creating a .resx for, as it happens, Croation but I can't get it to replace the English text of a label or button with the Croation equivalent. My understanding is that this should happen without any additional code.

As far as I can make out the approriate .resx is chosen on the basis of the Culture or UICulture setting. UICulture would seem to be the more likely. I can change Culture via Regional and Language Options but I can't find anyway to change UICulture which resolutely stays as English(US). I've tried R&LO Advanced options and rebooted but it made no difference.

Am I heading in the right direction with this and if so how do I change UICulture?
