Setting application's culture

I want to have the culture set in app.exe.config, and it should be used throughout the application. I think I need not change the UICUlture, my application will not be localised; I only want the number and date string presentations in one particular way.

What exactally are you wanting to do? Are you wanting to set your app to the default culture of your clients OS or are you wanting to specify it explicitly? If it's the first, then you don't have to do anything. The .NET Framework automatically defaults to the culture. If it's the second, then you will have to provide the culture code for the CurrentCulture property. Are you wanting to change the UI culture also? Let me know.
