Enums are simply integers so try using this when defining the StreamInfo structure with Struct. The first enumeration is 0 with each successive element incremented by 1.

It looks like you should be able to handle this with VFP. There are no complex structures (e.g. pointers to structures within structures). For that, I would recommend Ed Rauh's ClsHeap class.

HTH.
