When defining your oleserver.vfp8, add a mycollection property in the clas definition. That way the property will be built into the interface. When you attempt to access the mycollection property, you should be able to. Because of VFP's late binding in this case, you should then be able to access the properties of whatever is stored in that property (in this case, a collection).
