[vb6] Use the IS operator to compare objects

With ordinary variables you would use the = operator to compare different variables. This does not work with object variables. Instead you have to use the IS operator, e.g.:

    Dim MyObject as MyClass
    Dim MyOtherObject as MyClass
  
    Set MyObject = New MyClass
    Set MyOtherObject = MyObject
  
    'Now, the two object variables reference the same object. 
  
    If MyOtherObject Is MyObject Then
      'The message box should pop up:
      MsgBox "Yes, MyObject points to the same object as MyOtherObject and vice versa" 
    End If 

The IS operator must be used within an If - Then statement.
