>>>I have a container on which I have a crystal reports Active-X control. My idea was to use this container as a member of my application object so that I can reference reports easily throughout my app (something like goapp.oReport.ReportName = 'blah'). However, when I try to instanciate my container ( x=CreateObject('cntReport') )with the active-x control on it I get the error "object class is invalid for this container." I get this same error for any olecontainer control I drop on my container. Has anyone tried something like this and gotten any results? How can I add an active-x control to my container to be instanciated?

Yes, you can exclude container and have 'global' form object with OLEs.
