You can store crystal report files (*.rpt ) in program directory . On file (rpt) properties in solution explorer, set "Build action" - 'None', "Copy to Output Directory" - 'Copy if newer'.
The code to load report is:
dim rptFileName as string="GR01_rpt.rpt"
Dim rpt as new CrystalDecisions.CrystalReports.Engine.ReportDocument
rpt.Load(rptFileName)
Hope it will help.
