IsObject Function


Returns a Boolean value indicating whether an expression references a valid Automation object.


The expression argument can be any expression.

IsObject returns True if expression is a variable of Object subtype or a user-defined object; otherwise, it returns False.

The following example uses the IsObject function to determine if an identifier represents an object variable:

Dim MyInt, MyCheck, MyObject
Set MyObject = Me
MyCheck = IsObject(MyObject)   ' Returns True.
MyCheck = IsObject(MyInt)   ' Returns False.
