Help: Excel sort from VB.Net - How?

Hi,

Any ideas of the syntax required to perform an Excel sort from VB.Net?

Are there any Imports statements required, etc.?



Also, if I want the data in Column B centered, I use:

oSheet.Columns("B:B").HorizontalAlignment = 2

How can I relate this to xlCenter rather than using the number 2?



Thanks,

Greg.
