Crystal Reports displaying problem

I've included a Crystal Reports object into a project, and I need to control it and to display it in CrystalReportViewer component. When I've tryed to bind it in design for ReportSource property were no option although the report was in the project and its object was defined. I've tryed to it runtime but a line
crystalReport1 = new CrystalReport1 ();
makes an error with message "Invalid report file path". Tell me please how to make the component show the report.
