This demonstrates the importance of showing example code. 
Everyone who tried to help you in this thread was going on the 
assumption that you were using a library that does not deviate 
from standard practice. Personally, I had no idea that there were 
"COM" libraries that do that. When I did ask for example code, 
you still didn't post anything relevant, i.e. something that 
shows your interface declarations or how you were obtaining the 
COM pointer.

Generally, you want to give as much info as possible with these 
sorts of problems, including compiler, command line options, 
error messages, and anything you can think of that is relevant. 
That you were using ASIO should have been in your very first 
post. Please keep that in mind the next time you have an issue. 
It may save you a lot of grief.
