The situation is that.

Right now I have the VBA code as below:

Dim test
Sub macro1()
On Error Resume Next
Dim x As Variant
If test < Empty And test < Null Then
x = test.end()
Set test = Nothing
End If
On Error GoTo 0
Set test = CreateObject("Place.interface")
End Sub

And there is also a customized appllication programm is with
title"Place". And this one a user interface that you could see the
detail progress of the data processing.

But where I could find the definition of the object "Place", and also
class "interface". And also the class of "test".

I am confused.
