How to marshal interfaces across apartments in Visual C++

When using a STA COM on multi-threaded environment, we maybe got COM errors.
Because a STA COM Interface could not be shared throuth different threads.
If you want share a COM interface among threads, you shoud marshal a COM interface.
And If Application has a UI, we should message pump, so that It could be blocked while marshalling.
Reference this Microsoft KB article.
