My starting position:
I have a recursive function, which analyses the meta-structure of a
xml-document.
So far the (recursive) function has a parameter of the object-type
instead of an specified type!

Well, to cut a long story short:
What happens, when a 'object'-type-parameter (as object) is identified
(at runtime) as a concrete type?

An simple example:

Private Sub Form_Load()
Dim recset As ADODB.Recordset
...
' Wich of the two functions is faster?? And why?
Call function1(recset) ' Calls with As Object
Call function2(recset) ' Calls with As ADODB.Recordset
End Sub

Public Function function1(obj As Object)
' make something
End Function

Public Function function2(obj As ADODB.Recordset)
' make the same something as function1
End Function

Is it faster to write the specific type???
And why is it faster???
What happens internal???


thanx in advance...
