Hi,

A question about the method getCardCount() in the interface nsIAddressBook.
It needs a PRUint32 param but if I create a nsISupportsPRUint32 variable and 
pass it to the function, there is an error which says : can't set the "value" 
attribute.
This is normal because the nsISupportsPRUint32 has only a "data" attribute.

Is this normal ? What kind of object should I pass to the function ?

Thanks,

Cimballi
