I didn't try the code and didn't really read it.

K is for form's only. I also added V for VCX.

FOR EACH oFile in _VFP.ActiveProject.Files 
  IF oFile.Type $ "KV" && form
     USE (oFile.Name) ALIAS __FORM
     SCAN FOR __FORM.Class = 'ccombobox'
         =MESSAGEBOX(__Form.Objname)
     ENDSCAN

     USE IN select("__FORM")
  ENDIF
ENDFOR
