Avoid Database Login prompt when using CrystalReportViewer

Question

Is there a way to keep the Database Login prompt from coming up when using Crystal Reports runtime 2008 SP2? I'm using that plus Visual Studio 2008 to develop a Windows Form application to view reports on a client machine that accesses data on a seperate SQL Server 2005 machine. My customer would like to avoid having users manually enter anything everytime a report is opened with the Crystal Reports viewer.
I've used the following code with ODBC and OLE DB report connections. When I use ODBC, the prompt comes up with Integrated Security checked which must be cleared. When I use OLE DB, the prompt comes up with Database Name blank and greyed out so I cannot manually enter it.
Am I missing something here?
Imports CrystalDecisions.Shared
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Windows.Forms
Public Class Form1
    Private Sub setDatabaseLogon(ByVal myConnectionInfo As ConnectionInfo)
        Dim logOnInfos As TableLogOnInfos = CrystalReportViewer1.LogOnInfo
        For Each logOnInfo As TableLogOnInfo In logOnInfos
            logOnInfo.ConnectionInfo = myConnectionInfo
        Nex
    End Sub
    Private Sub ConfigureCrystalReports()
        Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo()
        setDatabaseLogon(myConnectionInfo)
        myConnectionInfo.DatabaseName = "ClearView"
        myConnectionInfo.UserID = "reports"
        myConnectionInfo.Password = "dstreports"
        myConnectionInfo.IntegratedSecurity = False
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ConfigureCrystalReports()
    End Sub
End Class

Thanks Jonathan for the tip. I tried it before and after the setDatabaseLogin call yesterday, but got the same results. I'm still going to follow your suggestion because that makes more sense.
Turns out it was the configuration of my ODBC/System DSN that was causing the problem. I reconfigured the System DSN by clearing the check box to provide username/password and now I don't get the Database Login anymore.
I found a different blog post that answered the OLE DB issue I was seeing where the DatabaseName was coming up blank:
Login Error Database at Runtime
Haven't tried it yet and probably won't because I got the Viewer to work with ODBC the way I like it.
Thanks for the help!
