I can't test it on Nothing and if I assign Nothing
IsNull(MyObject) returns false

From MSDN:

IsNull Function Example
This example uses the IsNull function to determine if a variable contains a Null.

Dim MyVar, MyCheck
MyCheck = IsNull(MyVar)   ' Returns False.

MyVar = ""
MyCheck = IsNull(MyVar)   ' Returns False.

MyVar = Null
MyCheck = IsNull(MyVar)   ' Returns True.

As said by ghimireniraj, you can set
Set MyObject = Nothing

And then check
If MyObject Is Nothing Then
  ' Code
End If

You said that you can't test it on "Nothing". Why?

MyCheck has to be declared as an Object becouse I use its methods later
And if a declare it as an object I can't assign Null to it or i don't know how.
