>With COM (VFP DLL) it's a bit trickier. You can see for yourself - download the ado query analyzer in the download section (it builds a DLL). Compile it in VFP 6 (i think it works under 8). Then compile it in VFP 9 (it breaks). I wrote Hsia about this issue - but no response. I did not learn about it until I tried to move a VFP IIS COM from 8 to 9. It seems that VFP 9 does not like COM's (DLLs) that issue a CREATEOBJECT .

It's documented change in the behavior in VFP9: "The ability to have a property assignment set to instantiated object is no longer supported in a class definition and will generate an error".
