 Thanx

You have to link to UUID.lib when using most COM stuff (DirectX included). 
Just put it on the commandline and it should link it in.

Hahahaha...cool man, it worked just fine!
What uuid.lib contains, why is it needed for com and directx? I just want to
understand the problem.

It contains all the GUID definitions (you know, those insanely long 
hexadecimal numbers) for a large number of COM interfaces.  It's how Windows 
uniquely identifies those interfaces.  It's a rather extensive list so it's 
easier to keep them all in a library than to have a gigantic header file 
filled with them.
