[Guest_imported]

hello:
I use CR4.6,when I want print one record from database,
I will write :
crystalreport1.SelectionFormula="{abase.idcode} = 2001"

Now I begin to use CR8 ,so the old version's *.rpt is changed to Form1 and crystalreport1 , how can i do just as top example ?and how to use
report.Database.AddADOCommand (pconnection,pcommand)?

thanks.
