Passing parameters to external Crystal 2008 report

Question

I have to invoke the viewer.reportsource twice in order for the parmeters to a Crystal Report to take effect.
Here is my environment:
CR 2008
VS 2005
VB
SQL Server 2008
External Crystal Report
I am using the Report Document Object.  Here is the code I am using
' The following is a Class used to configure a Crystal report Document
'    Structure struRptParms '
        ' This structure will be used to hold Crystal Reports Parameter Keys and Parmeter Values
        Public strRptParmKey As String
        Public aryRptParmValues As ArrayList
    End Structure
    ' aryRptParms is an ArrayList property of this class that contains the ParmKeysAndValues for the report
        ' Step 1 - Instantiate a Crystal report document for the Report and then
        '           load the report into the report document
        '   a) instantiate the ReportDocument class.      
        docCrystalReportDocument = New ReportDocument
        '   b) Load the report by a Call to the Load() method of the ReportDocument instance
        '       and pass it the reportPath string variable.
        docCrystalReportDocument.Load(strRptPathAndName)
        ' Step 2 - Create the links to the Data Source for the Report
        '   a)instantiate the ConnectionInfo class
        Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo()
        '   b) set the ServerName property of the ConnectionInfo instance.
        myConnectionInfo.ServerName = strRptDataSource.ToString
        '   c) Set the DatabaseName and IntegratedSecurity properties of the ConnectionInfo instance.
        myConnectionInfo.DatabaseName = strRptDataBase.ToString
        myConnectionInfo.IntegratedSecurity = True
        ' Step 3) Connect the report to the datasource by entering a call to the
        '           SetDBLogonForReport() method, by passing in the ConnectionInfo instance and the Crystal report.
        SetDBLogonAndDataSourceForReport(myConnectionInfo, docCrystalReportDocument)
        ' Step 3a) Connect subreports to the datasource by entering a call to the
        '           SetDBLogonForReport() method, by passing in the ConnectionInfo instance and the Crystal report.
        Dim mySubReportDocument As ReportDocument
        For Each mySubReportDocument In docCrystalReportDocument.Subreports
            SetDBLogonAndDataSourceForReport(myConnectionInfo, mySubReportDocument)
        Next
        ' Step 4) Pass the parameter keys and parameter values to the report by calling
        '           the SetParameterValue() method from the Report Document class. Do this for
        '           each instance of parameter keys and values passed in via aryRptParms property
        Dim struMyRptParms As New struRptParms
        For Each struMyRptParms In aryRptParms
            docCrystalReportDocument.SetParameterValue(struMyRptParms.strRptParmKey.ToString, struMyRptParms.aryRptParmValues.ToArray())
        Next
        ' Step 5) Connect the Crystal Report to the report viewer by binding the ReportSource property of the
        '       CrystalReportViewer to the ReportDocument instance
        Me.vwrCrystalReport.ReportSource = docCrystalReportDocument
        Me.vwrCrystalReport.ReportSource = docCrystalReportDocument

Jonathon,
Thank you for reading my post and taking the time to reply. 
The report design does not have Save Data turned on.
I moved the parameter passing before logging on to the data base - that did not fix the problem.
Thank you again for taking the time.
