WU_E_INVALID_OPERATION not defined in wuapi.h file

Hi there,

I'm using the Windows Update Agent APIs to automate the update of the
Windows system. The COM interfaces seems to work correctly however a lot of
constants are missing from the wuapi.h file.

E.g WU_E_INVALID_OPERATION error returned by IUpdateDownloader:ownload is
not defined in wuapi.h.

Any ideas where these WU_E_* constants are defined? The wuapi.h I downloaded
from Microsoft has no defines in it.

Thanks.
