Project References

how can I include references to objects with the same name. At the moment I use the users outlook account to send emails from my application . This is done by including a reference to the outlook dll. The problem comes if the user has a different version of outlook on there pc to mine on the compilation pc. What I want is to be able to email from my application using outlook express,97,2000,2002 dependent on what they have installed but I can't include references to more than 1 as they have the same name any ideas?

Maybe you could use late binding and CreateObject("Outlook8") or whatever its called to just use the version on that machine. You'd have to declare it as a generic object and it would lose some performance but....
