Adding WMI interface to storminiport driver.

Hi All,

I am working on adding wmi interface to storminiport driver.As of now , i have implemented QueryWmiDataBlock and SetWmiDataBlock.I am testing it by using the wbemtest utility.
when i issue the query "select * from ,it is calling querywmidatablock in my miniport driver.It is fetching the proper values and same is showing in wbemtest.
but when i make an attempt to change the values,it is not calling SetWmiDataBlock routine.i played arround with the object properties and tried to change the values.But , it is not invoking my SetWmiDataBlock in my miniport driver.Can anyone please tell me how to change/edit the values using wbemtest.

with thanks,
