Modifying DLLs

I designed an application that uses an Active-X dll. The dll has a few classes and a couple template classes. When I change any of the code in the dll, such as modifying a subroutine that may have a bug, and attempt to run a previously compiled version of the main appliction, I get the following error, runtime error 429, ActiveX component can't create object. I thought one of the advantages of "componentizing" an application was that you could update the component without updating the main application. Is there anyway you can do this without recompiling the main application?

This problem was solved by setting that the compatibility for the ActiveX dll project (Project Properties ... compatibility tab) to binary (or none), instead of the default, project.
