Need help in Referencing objects in run time

[Venkat Ravi]

HI,

I have two controls of third party with followin names

xyz.dll which references Type libraray of Application 1 and
xyz.dll which references Type libraray of Application 2

Incidentally names of Type libraries of these two applications are same and
i need to work with both of them in run time after creating an executable

Question: Can i add a reference to application1 in runtime and then changing
reference to applicaition 2 in runtime ?

thanks
