Crystal Report now working on second load.

Hello everyone,

I need some advice on the following code

Code:

---

        ds.Clear()

        ConnecttoDatabase()

        SQLCommand = vbNullString
        SQLCommand += "SELECT * FROM producttable p "
        SQLCommand += "WHERE NOT barcodenumber='' AND "
        SQLCommand += "p.useonweb='1' AND p.itemstatus='1' AND NOT "
        SQLCommand += "EXISTS(SELECT '' FROM productimage v "
        SQLCommand += "WHERE v.productcode = p.barcodenumber) "
        SQLCommand += "order by suppliername ASC;"

        MySQLCmd = New MySqlCommand(SQLCommand, dbCon)

        'open connection
        dbCon.Open()

        MySQLCmd.CommandText = SQLCommand

        dr = MySQLCmd.ExecuteReader

        With dr
            Dim t As DataTable = ds.Tables.Add("Items")
            t.Columns.Add("BarcodeNumber", Type.[GetType]("System.String"))
            t.Columns.Add("SupplierCode", Type.[GetType]("System.String"))
            t.Columns.Add("SupplierName", Type.[GetType]("System.String"))
            t.Columns.Add("PoSDescription", Type.[GetType]("System.String"))
            t.Columns.Add("SELDescription", Type.[GetType]("System.String"))

            While .Read
                Dim r As DataRow
                r = t.NewRow()
                r("BarcodeNumber") = .Item("BarcodeNumber")
                r("SupplierCode") = .Item("Supplierproductcode")
                r("SupplierName") = .Item("SupplierName")
                r("PoSDescription") = .Item("PoSDescription")
                r("SELDescription") = .Item("shelfedgelabelDescription")
                t.Rows.Add(r)

            End While
        End With

        Dim report As New ReportDocument()
        Dim reportPath As String = Application.StartupPath & "\Report\ItemWithnoImages.rpt"
        report.Load(reportPath)
        report.SetDataSource(ds.Tables(1))

        With frmReport
            With .CrystalReportViewer1
                .ReportSource = Nothing
                .DisplayGroupTree = False
                .Zoom(2)        ' Full page
                .ReportSource = report
                .Refresh()
            End With

            frmProcessing.Close()
            .Show()
            .Focus()
        End With

The report works first time with no problem but on any other time I get a blank report. What am I missing?

Put the code in a Try/Catch block and see if you get any errors.
