something wrong with collections

Why doesn't Visual Basic let me add a user defined type structure variable to a collection?
Whenever i try to do that it gives me this compile error message:

"Only user-defined types defined in public object modules can be coerced to or from a variant or pressed to late-bound functions."

Please note that I defined my type strcture in public module. This error happens on this statement

Notes.Add Item:=newnote, Key:=Str(CurNote)

'newnote' is the variable that is declared as type structure. And 'Notes' is my collection.

Any idea?

Erick37,

I read that page but it doesn't quite help me because it deals more with activex servers you create. In my case, i am dealing with Collection. I can't possible modify that because it's built in Visual Basic.

so what do you think i should do?

Anybody?

Hi
What's about making class module Note with Public variables (or Properties) same as in your UDT. Then:
Dim Notes As New Collection
Dim newnote as Note
......
Set newnote = New Note
Notes.Add Item:=newnote, Key:=Str(CurNote)

Cheers

The standard Collection object will accept any value that can be stored in a Variant. Unfortunately you cannot store a UDT in a Variant.

If you must use the standard Collection object the only alternative is to convert your UDT to a Class as suggested by Ark.
