I had hoped others would continue development on typelib stuff, picking 
up from where I left off after the rewrite to use more of 
VariantChangeType, but unfortunately this isn't the case and I don't 
have enough time to work on this area too much. Fortunately, I don't 
think there are too many issues left to fix and already the new code in 
ITypeInfo::Invoke gets some programs working that wouldn't work with the 
old code.

Does this patch fix both issues for you?
