Question

我创建水晶报告，询问用户输入... i用户参数字段，询问开始日期和结束日期以获取报告...

一切顺利，直到用户提交他们的开始和结束日期......

水晶报告不断询问数据库的密码，除非我把它写在代码中......这里是我的代码

Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click
    If DropDownList1.SelectedValue = "Jam Masuk" Then
        Dim reportdocument As New ReportDocument()
        reportdocument.Load("D:\MIS Project\Master Project MIS\BSTM\Security\ReportTamuMasuk.rpt")
        reportdocument.SetDatabaseLogon("sa", "P@ssw0rd")
        reportdocument.SetParameterValue("Akhir Jam Masuk", Label2.Text)
        CrystalReportViewer1.ReportSource = reportdocument
        CrystalReportViewer1.Visible = True
    ElseIf DropDownList1.SelectedValue = "Jam Keluar" Then
        Dim reportdocument As New ReportDocument()
        reportdocument.Load(Server.MapPath("ReportTamuKeluar.rpt"))
        reportdocument.SetDatabaseLogon("sa", "P@ssw0rd")

我有同样的问题，但我找到了一个简单的解决方案。你只需要用数据表替换数据集，它就能正常工作..

我使用此代码进行oracle连接，并使用CRAXDRT.dll在c＃中创建报告，也许它可以帮助您：

CRAXDRT.DatabaseTable T;
        for (int i = 1; i <= report1.Database.Tables.Count; i++)
        {
            T = (CRAXDRT.DatabaseTable)report1.Database.Tables[i];
            CRAXDRT.ConnectionProperties cps = T.ConnectionProperties;
            CRAXDRT.ConnectionProperty cp =
                (CRAXDRT.ConnectionProperty)cps["User ID"];
            cp.Value = "Username";//DB.Username;

            cp = (CRAXDRT.ConnectionProperty)cps["Password"];
            cp.Value = "Password";// DB.Password;

            cp = (CRAXDRT.ConnectionProperty)cps["Data Source"];
            cp.Value = "DataSource";//DB.DataSource;

            T.SetLogOnInfo("DataSource", "", "Username", "Password");
        }

您要求的报告需要更多信息
