>Does anyone have code that can test for the existence of a class object from within a method of another class object? For example lets say that I create a LAST command button as an independent button. I want it to perform its normal function of going to the last record, this is easy, but I also want it to test for the existence of a NEXT button and If it exists disable it. I know this is easy if you create a container and let the container control what happens. But for purposes of theory, lets say we cant or wont use a container. Since theoretically, these two buttons will be used alot they are to be created as classes. So again, how do I test for the existence of another class object?

if 2 objects are not contained together in a container of some sort
they shouldn't know anything about eachother
let say u can check if another object exist (I think this shouldn't be a problem using the TYPE command btw) what would be the path you would search it in
also disabling another nonrelated object violates encapsulation
