Please Help: Transferring from Dictionary to Array
 

Column A in my worksheet contains repetitive values. I have a macro that
creates a dictionary object and loads it with unique values from the column.
When I try to load the dictionary items into an array, its not working out.
The array does not seem to contain any values (as the msgbox function is not
returning anything). The macro is pasted below.

I cant figure out what I'm doing wrong. Any help would be greatly appreciated.

Thank You!

ReDim arr(1 To x.Count)

For Each Item In x.Items
i = 1 + i
arr(i) = Item
Next Item

For t = 1 To UBound(arr, 1)
MsgBox arr(t)
Next t

End Sub

Using a For Each loop on a Dictionary is a little strange.
It is setup differently and the for/each variable must be a variant or object.
Also, the Items method of the Dictionary returns a zero base variant array.
So it can be dumped directly into a Variant variable....
