As long as the COM object is fully compliant with the standards. There are many COM objects that don't follow the standards, but work with VB 6.0 because VB is more forgiving than VFP. When I was writing my book, I was having some problems with Crystal automation on something that worked in 8.5, but not in 9. I asked about it on the MVP forum and it eventually made its way to Calvin who confirmed that Crystal had a bug.

>What does this have to do with VFP? VFP can be used for automating any COM object, but VFP is not going to be listed in every case an example is made for scripting, like VBA or VB. Plus, I don't know many (or any) VFP developers using Great Plains with VFP, they generally use 3rd party accounting applications that are VFP based.
