本文介绍了水晶报表:无效的索引。 (从HRESULT异常:0x8002000B(DISP_E_BADINDEX))的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我不能值传递到报告。

这是我的code:

 公共无效GLRPT()
        {
            尝试
            {                ReportClass rptH =新ReportClass();
                rptH.FileName =使用Server.Mappath(〜/ RPTS / G1.rpt);
                rptH.Load();                字符串DF =会话[寄件者]的ToString()。
                串DT =会话[TODATE]的ToString()。
                日期时间寄件者= DateTime.Parse(DF);
                日期时间TODATE = DateTime.Parse(DT);                rptH.SetParameterValue(Date_From?,寄件者);
                rptH.SetParameterValue(?DATE_TOTODATE);
                rptH.ExportToHtt presponse(ExportFormatType.PortableDocFormat,System.Web.HttpContext.Current.Response,假的,GL);
            }
            赶上(异常前)
            {
                的Response.Write(ex.Message);
            }
        }

我不知道为什么我会看到此错误:
结果
无效的索引。 (从HRESULT异常:0x8002000B(DISP_E_BADINDEX))


解决方案

我们应该传递的参数值是这样的:

  rptH.SetParameterValue(Date_From,寄件者); //正确

不会

  rptH.SetParameterValue(?Date_From,寄件者); //不正确

然后,我们就要给数据库访问以报告,因为没有登录到数据库将无法打开该报告。
这里是code:

 的ReportDocument rptH =新的ReportDocument();
TableLogOnInfos crtableLogoninfos =新TableLogOnInfos();
TableLogOnInfo crtableLogoninfo =新TableLogOnInfo();
ConnectionInfo crConnectionInfo =新ConnectionInfo();
表CrTables;rptH.Load(使用Server.Mappath(〜/ RPTS / G1.rpt));字符串DF =会话[寄件者]的ToString()。
串DT =会话[TODATE]的ToString()。
日期时间寄件者= DateTime.Parse(DF);
日期时间TODATE = DateTime.Parse(DT);rptH.SetParameterValue(Date_From,寄件者);
rptH.SetParameterValue(DATE_TO,TODATE);crConnectionInfo.ServerName =服务器名称;
crConnectionInfo.DatabaseName =数据库名称;
crConnectionInfo.UserID =您的数据库用户名;
crConnectionInfo.Password =你的数据库密码;CrTables = rptH.Database.Tables;
的foreach(CrystalDecisions.CrystalReports.Engine.Table CrTable在CrTables)
{
    crtableLogoninfo = CrTable.LogOnInfo;
    crtableLogoninfo.ConnectionInfo = crConnectionInfo;
    CrTable.ApplyLogOnInfo(crtableLogoninfo);
}rptH.ExportToHtt presponse(ExportFormatType.PortableDocFormat,System.Web.HttpContext.Current.Response,假的,GL);


  

我们必须调用参数的名称没有任何额外的字符
   @ ,仅仅只有参数的名称本身。


I can not pass values to the report.

This is my code:

public void GLRPT()
        {
            try
            {

                ReportClass rptH = new ReportClass();
                rptH.FileName = Server.MapPath("~/Rpts/G1.rpt");
                rptH.Load();

                string df = Session["fromdate"].ToString();
                string dt = Session["todate"].ToString();
                DateTime fromdate = DateTime.Parse(df);
                DateTime todate = DateTime.Parse(dt);

                rptH.SetParameterValue("?Date_From", fromdate);
                rptH.SetParameterValue("?Date_To", todate);
                rptH.ExportToHttpResponse(ExportFormatType.PortableDocFormat, System.Web.HttpContext.Current.Response, false, "GL");
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
        }

I don't know why I see this error:
Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))

解决方案

We should pass the parameter value like this:

rptH.SetParameterValue("Date_From", fromdate); //correct

NOT

rptH.SetParameterValue("?Date_From", fromdate); //incorrect

Then we we must give database access to the report because without login to database the report will not be opened. and here is the code:

ReportDocument rptH = new ReportDocument();
TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
Tables CrTables;

rptH.Load(Server.MapPath("~/Rpts/G1.rpt"));

string df = Session["fromdate"].ToString();
string dt = Session["todate"].ToString();
DateTime fromdate = DateTime.Parse(df);
DateTime todate = DateTime.Parse(dt);

rptH.SetParameterValue("Date_From", fromdate);
rptH.SetParameterValue("Date_To", todate);

crConnectionInfo.ServerName = "YOUR SERVER NAME";
crConnectionInfo.DatabaseName = "YOUR DATABASE NAME";
crConnectionInfo.UserID = "YOUR DATABASE USERNAME";
crConnectionInfo.Password = "YOUR DATABASE PASSWORD";

CrTables = rptH.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
{
    crtableLogoninfo = CrTable.LogOnInfo;
    crtableLogoninfo.ConnectionInfo = crConnectionInfo;
    CrTable.ApplyLogOnInfo(crtableLogoninfo);
}

rptH.ExportToHttpResponse(ExportFormatType.PortableDocFormat, System.Web.HttpContext.Current.Response, false, "GL");

We must call the parameter's name without any additional character such as @ or ?, just only the parameter's name itself.
