2005 Help center is it complete or is it the wrong file..?

Ihave just downloaded the 2005 sdk help Center to get some information abou the UserQueries Object and the downloaded file (b1_sdk.zip) starts off with the homepage titled

'SAP Business One SDK 2004' !! and no ref at all to the UserQueries Object.

so question is twofold

is the 2005 SDK helpcenter incorrect(ie Wrong file linked)

and 2 where can I get some detail about the UserQueries Object

thanks..
