Some help with regional settings needed

Question

Hello... I need to change the regional settings used by my application but leaving the system regional settings intact to be used by other applications. I have tried changing Application.CurrentCulture property to use my custom regional setting on my C# application and almost everything I need works ok, but the problem comes when I create a new thread because it takes the original system regional settings. I need to know if there is a way to make new threads and everything created by the main application take automatically my custom regional settings or if there is a way to make my application detect when a new thread is created and execute some code then... Please, can anybody help me? Thank you all in advance. Xavier
