VBA Type Mismatch on CustomOrder

Question

I have this code which works great:

Sub NewSortTest()
    ActiveWorkbook.Worksheets(\"Sheet1\").Sort.SortFields.Clear
    ActiveWorkbook.Worksheets(\"Sheet1\         


        

Answer 1

Glad you figured it out. The following also works (per this post):

Sub NewSortTest()
ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Clear
ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Add Key:=Range("A1:A20"), _
                                                        SortOn:=xlSortOnValues, _
                                                        Order:=xlAscending, _
                                                        CustomOrder:=keyRange, _
                                                        DataOption:=xlSortNormal
With ActiveWorkbook.Worksheets("Sheet1").Sort
    .SetRange Range("A1:B20")
    .Header = xlGuess
    .MatchCase = False
    .Orientation = xlTopToBottom
    .SortMethod = xlPinYin
    .Apply
End With
End Sub

Function keyRange() As String

keyRange = "alpha,bravo,charlie,delta,echo,foxtrot,golf,hotel,india,juliet"

End Function

Edit: Even easier

CustomOrder:=CVar(keyRange)

Edit: Why Does This Work?

I've been trying to figure that out myself. The help documentation on the CustomOrder property lacks any meat, as you found out in your search. I've been experimenting with different things to see if I could get at an answer, and I haven't had much luck. I think CustomOrder is doing some magic in the background. It does just fine with a String literal or a Long, as you found out. And it has no poblem with a String properly cast as Variant. But it doesn't like String variables. It must have something to do with String variables being reference types. I have no idea why it wouldn't be able to handle that, but I also don't know how it creates a custom list on the fly from a String literal. If you find anything that explains it, I'd love to know.
