Hi,
     We are facing some problems in using  Crystal reports
 over remoting.
 	We have middle tier class  which has method to
create ReportDocument object. The windows client creates the object of
middle tier class using remoting. Then executes the method of same , to
get the ReportDocument object.
 	But when we bind the object to ReportSource property
of Report viewer it threw the 
exception "CrystalReports.Engine.Formatengine is
not marked as serializable. ". One obervation made was
the return object is of type transparentproxy instead of
ReportDocument
 	If u knew anything of this, please let us
know.(Aleternative solution will be welcome)
 	Please note that we donot have IIS on middle tier
hence web service cannot be used.
 
 thanx,
 Vishal
