Yes, you do. If the method took a BSTR **, then you could pass a pointer to a BSTR * which would then get allocated by the callee which knows the number of items in the array, but with the current situation, you need to figure out how to find the number of items in the array. -- Ehsan Akhgari Farda Technology <http://www.farda-tech.com/> In C we had to code our own bugs.
