Set a type in VBA to nothing?

Question

I have defined a variable with an own type, say

Dim point As DataPoint

Public Type DataPoint
   list as Collection
   name as String
   number as Integer
End Ty

The standard way is to reset each member to its default value individually. This is one limitation of user-defined types compared to objects.

At the risk of stating the obvious:

With point
    Set .list = Nothing
    .name = ""
    .number = 0
End With

Alternatively, you can create a "blank" variable and assign it to your variable each time you want to "clear" it.

Dim point As DataPoint
Dim blank As DataPoint

With point
    Set .list = New Collection
    .list.Add "carrots"
    .name = "joe"
    .number = 12
End With

point = blank 
' point members are now reset to default values
