You might try using the code I posted in FAQ 696 for creating a SafeArray as a memory structure and passing a pointer to it, assuming it wants a SafeArray. If not, you might try stringing together a ULONG for the value 3, followed by the three doubles converted to strings (there's conversionn code for creating doubles in memory in my ClsHeap class.)
