DATABASE opens in vb 2010

I have an open  database statement that seems to work when the first window is opened. I thought that this would keep the database open throughout the application.

        Dim dbconn As New SqlConnection
        Dim sqlConn As SqlConnection = New SqlConnection("MCLE_SQL2008\MCLE_SQL2008;Initial Catalog=iMIS_MCLE_Prod;User ID=sa;Password=**********")
        dbconn.Open()

I have a form that contains a Crystal viewer and a Crystal Report.  The report will run correctly, but it prompts for the sa password when you refresh the report manually. If the database is open already, why does it prompt again, and is there a way to eliminate this?

Crystal uses its own database connection not the one that is in the application,

There is a method you can use to create the recordset in the application then pass it to the report.

I'm not using ADO.  The Crystal report as it exists runs quite nicely from VB6... Iknow, Iknow old technology....but it work with minimal pain.

Does this mean the report has to be re-written to accommodate VB 2010?

I just can't see giving the sa password to staff.

Is there a way to pas the database access method to the CR?

Missed it was on the refresh.

The refresh causes a postback which you have to handle.
I don't know how to handle it but I know you have to save the user/password in session variables.
