I have a listview I want to sort via column click. Problem is, I want it based on content. I am using this right now:

    With lvResults
        .SortKey = ColumnHeader.Index - 1
        .SortOrder = IIf(.SortOrder = lvwAscending, lvwDescending, lvwAscending)
        .Sorted = True
    End With

Which works fine for text, but horribly for numbers.

How do I modify this so that it will sort numbers as numbers instead of a string?
