Hi,

There's one major problem I missed previously:

This won't work. There's a & too much.

Please consider adding tests for String and Binary types to catch this
kind of thing. GetComponentByName once had the same problem I believe.

Minor stuff:
> +    TRACE("(%p)->(%d %p %p %p %p %p)\n", This, dwComponentID, pwszName, pdwNameLen, pvBuffer, pdwBufferSize, pdwDataType);
pdwNameLen, pvBuffer, pdwBufferSize, pdwDataType);
A DWORD is unsigned, %u is better.

You forgot to add a WARN here.
