CRVS2010 Beta - Setting 'SA' password

Hello,

I just installed cr for vs2010, and i found in toolbox the "CrystalReportViewer" i drg it to my form and in the form load i put that code:

str = "C:\PO_Customer.rpt"

        Me.CrystalReportViewer1.ReportSource = str

The report is openning but before it asking me the passwords for 'SA', i enter the passowrd and everything is workiing,

My question is: Where can i set this password in my application to stop asking the password when openning the report?

Thank's a lot
