How to test if an object exist really
 

Hie,
I try (unsuccesfully to test if an object of my own is "Nothing" or not
I created an object class, let's call it MyClass.
Thren I declared an instance of this variable like this:

Dim MyObj as new MyClass
Dim boTest as boolean

Set MyObj = Nothing
boTest = MyObj Is Nothing

Strangely, boTest is false! (I hoped this test retrun was true)
The question is : where did I make a mistake.
Thanks for your help.

Try:

Set MyObj = New myClass
Set MyObj = Nothing
boTest = MyObj Is Nothing

And then read Chip Pearson's explanation:

Instead of

Dim MyObj as new MyClass

use

Dim MyObj as MyClass
