The standard way to test whether two object variables point to the same object is through the Is operator, as in: Click here to copy the following block If obj1 Is obj2 Then ... However, when both object are of the same type, or point to the same secondary interface, you can slightly optimize your code by testing whether the values returned by the ObjPtr() function match: Click here to copy the following block If ObjPtr(obj1) = ObjPtr(obj2) Then ... This second line of code is about 40% faster than the Is operator. However, both statements are so efficient that you should perceive a difference only if the comparison is inside a time-critical loop that is executed some hundreds thousand times.
