IsObject( identifier )
The required identifier argument is a variable name.
IsObject is useful only in determining whether a Variant is of VarType vbObject. 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 VarType vbObject, 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.
This example uses the IsObject function to determine if an identifier represents an object variable. MyObject and and YourObject are object variables of the same type. They are generic names used for illustration purposes only.
