Steve,
AFAIK, you can't do this nativly in VFP. You may be able to create a Safearray using Ed Rauh's FAQ#7979. If you don't want to delve into the depths of the API, you can simply apply the filter within VFP by explicitly checking the class property within the FOR EACH ... ENDFOR loop.

I haven't done any performance testing to see if one way is faster or not.

HTH.

I have tried various approaches to setting the filter property, but so far nothing works. In the script, the filter is assigned as
