Mone,

is it possible that my GetItens method, recives only an Identification Number (my clientID, for exemple) as parameter? With this clientID, inside GetItens method, i can execute a query that returns all Company's ids that a specific client wants to see.
"Format" this result to be returned as a string array.

Can i do something like this or must i have to pass as parameter the string of companys IDs separeted with spaces ( "CompanyA CompanyB ..." )
