IsObject Function

See Also Example Specifics

Returns a Boolean value indicating whether an identifier represents an object variable.

Syntax

IsObject(identifier)

The required identifier argument is a variable name.

Remarks

IsObject is useful only in determining whether a Variant is of VarTypevbObject. This could occur if the Variant actually references (or once referenced) an object, or if it contains Nothing.

IsObject returns True if identifier is a variable declared with Object type or any valid class type, or if identifier is a Variant of VarTypevbObject, or a user-defined object; otherwise, it returns False. IsObject returns True even if the variable has been set to Nothing.

Use error trapping to be sure that an object reference is valid.
