WinForms have a flat structure, not like VFP, where you have the container and other controls being able to contain further controls. That alone makes it impossible. Plus VFP can't create ActiveX controls. You can only make a COM EXE with olepublic VFP Forms and use them from any COM capable language. If you make your olepublic vfp form withoiut a tilebar and borderless and use winapi to make the winform the parent of the vfp form you could embed some vfp "control" into a Winform, haven't tried to do so, and it feels cumbersome, not really worth it.
