VFP has been able to pass an array of VT_UI1s since VFP 6 at least, but only in VFP 8 can you pass these to a COM server BY_REF. This was required by a business partner of my client that wrote COM servers that had to run and pass data streams on all Windows language versions. The VB and C++ clients and servers forced a conversion to Unicode which screwed up the data stream if passed as a string. COMARRAY just didn't work as advertised for these arrays until now. This one lack caused the client to ditch VFP a couple of years ago as evidence that VFP was a "weaker" tool than VB. This was in spite of VB's poor data handling capabilities. Management didn't have the technical expertise to properly evaluate the tools. Oh well, better late than never.
