Question

我在我的表单上创建了一个名为Inv1和CrystalReportViewer1对象的新Crystal报表,它使用一个强定义的数据集来显示表中完美运行的所有记录.但是我现在正试图将我的结果限制为仅根据下面的SQL SELECT语句显示1条记录.但我在Crystal Reports下面收到运行时错误.

错误收到......

我目前正在使用另一种形式的代码.

Dim objRpt As New Inv1 Dim invoiceDS As New DataSet

    Dim q As String = "select * from inv_data INNER JOIN res_data ON inv_data.inv_res_id = res_data.res_id WHERE inv_res_id = " & EditResID
    GetFromDB(invoiceDS, q)

    objRpt.SetDataSource(invoiceDS.Tables("table"))
    ViewReport.CrystalReportViewer1.ReportSource = objRpt
    ViewReport.CrystalReportViewer1.Refresh()
    ViewReport.Show()

尝试将此添加到.config文件(通常是app.config)

<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
