I've tried to debug a VB com+, but without luck.

I looked at a lot of guides, such as http://support.microsoft.com/kb/919519
but none seem to work. A lot of it is because I'm supposed to attach to or run dllhost.exe, and then I'm told that it doesn't hold any debug info.
Some guides claim I should use visual c++, although I fail to see how that should be able to debug vb code.

Anyone have a bright idea?
