    Dim currentculture As String = My.Application.Culture.Name
    MsgBox("Current culture is " & currentculture)

    Dim jan1 As New Date(2005, 1, 1, 15, 15, 15)

    My.Application.ChangeCulture("en-US")
    MsgBox("Date represented in en-US culture: " & jan1)
    ' 1/1/2005 3:15:15 PM

    My.Application.ChangeCulture("")
    MsgBox("Date represented in invariant culture" & jan1)
    ' 01/01/2005 15:15:15

    ' Restore the culture.
    My.Application.ChangeCulture(currentculture)
End Sub

Remarks

The My.Application.ChangeCulture method changes the current thread's CurrentCulture property. CurrentCulture determines the default formats for dates, times, currency, numbers, sorting order of text, string comparisons, and casing for all computations on that thread.

To retrieve the current culture, you can use the Culture property or the CurrentCulture property.

The CurrentCulture setting is different from a language setting. It contains only data related to the standard settings for a geographical region. Therefore, the CurrentCulture property can only be set to a specific culture or to the InvariantCulture.

Use the My.Application.ChangeUICulture method to change the culture that the current thread uses for retrieving culture-specific resources.
