VBA check if object is set

Question

I have a global variable that is an instance of my custom class.

How do I check if the object is set or if I need to initialize it?

Answer 1

If obj Is Nothing Then     ' need to initialize obj: '     Set obj = ... Else     ' obj already set / initialized. ' End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then     ' obj already set / initialized. ' Else     ' need to initialize obj: '     Set obj = ... End If
