crd.load("my report place\crystalreport1.rpt")
dim crpfds as parameterfielddefinitions
dim crpfd as parameterfielddefinition
dim crpv as new parametervalues
dim crpdv as new parameterdiscretevalue
crpdv.value=textbox1.text
crpfds=crd.datadefinition.parameterfields
crpfd=crpfds.item("my parameter name")
crpv=crpfd.currentvalues
crpv.clear
crpv.add(crpdv)
crpfd.applycurrentvalues(crpv)
crystalreportviewer1.reportsource=crd
crystalreportviewer1.refresh
