when does crystal.net license counting starts

[janardan]

Hi,
I am using Crystal.net.
I just wanted to know that when exactly the license counting starts in crystal 9.
1. when I declare any variable from CrystalDecisions namespace.
like:
Dim rpt As ReportDocument
2. when I create a new report object.
like:
Dim rpt As ReportDocument = new MYReport()
3. when actually the report gets the data.
CrystalReportViewer1.ReportSource = rpt

and when It releases the license.
Thanks
Janardan
