客户端中的Crystal Report错误 [英] Crystal Report error in client
问题描述
我使用Oracle 11g在C＃4.0中开发了一个桌面应用程序，并在VS 2010中使用了Crystal报表
它在开发机器中执行和运行良好我创建了一个设置文件
在客户端系统中我安装了oracle客户端和我的应用程序的安装文件
能够使用应用程序，直到我生成任何水晶报告
有关调用

在网上搜索时，有想法在编码中声明名称和密码，所以我修改了CrystalReport的Form Load_event编码，如下所示但没有用
private void VisitorIDReportWindow_Load（object sender，EventArgs e）
{
if（this.CON.State.Equals（System.Data.ConnectionState.Open））
{
CON.Close（）;
}
CON.Open（）;
DataTable DTB;
string query1 =从VMS_VISITOR中选择*，其中PASSNUMBER ='+ VisitorCreationWindow.PNBR +';
使用（OLCMND1 =新的OracleCommand（query1，CON））
{
using（OADAP1 = new OracleDataAdapter（OLCMND1））
{
DTB = new DataTable（）;
OADAP1.Fill（DTB）;
}
}
RDT = new ReportDocument（）;
string reportpath = System.Windows.Forms.Application.StartupPath.Substring（0，System.Windows.Forms.Application.StartupPath.Substring（0，System.Windows.Forms.Application.StartupPath.LastIndexOf （\\））。LastIndexOf（\\））;
reportpath + = @\ VisitorIDReport.rpt; // string reportpath =D：\\Visitor Management System \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
RDT.Load（reportpath）;
ConnectionInfo connectioninfo = new ConnectionInfo（）;
connectioninfo.DatabaseName =ORCL;
connectioninfo.UserID =itapps;
connectioninfo.Password =it123;
Logindetailforreport（connectioninfo，RDT）;
VisitorIDCrystalReportViewer.ReportSource = RDT;
RDT.SetDataSource（DTB）;
}
对于异常，我无法理解..
I developed a desktop application in C# 4.0 with Oracle 11g & used Crystal report for VS 2010

2nd even if i click continue its asking me server username & password
when searched in net, there are ideas to declare the name & password in coding so i modified coding for CrystalReport's Form Load_event like below but no use
private void VisitorIDReportWindow_Load(object sender, EventArgs e)
{
if (this.CON.State.Equals(System.Data.ConnectionState.Open))
{
CON.Close();
}
CON.Open();
DataTable DTB;
string query1 = "Select * from VMS_VISITOR where PASSNUMBER ='" + VisitorCreationWindow.PNBR + "'";
using (OLCMND1 = new OracleCommand(query1, CON))
{
using (OADAP1 = new OracleDataAdapter(OLCMND1))
{
DTB = new DataTable();
OADAP1.Fill(DTB);
}
}
RDT = new ReportDocument();
string reportpath = System.Windows.Forms.Application.StartupPath.Substring(0,System.Windows.Forms.Application.StartupPath.Substring(0,System.Windows.Forms.Application.StartupPath.LastIndexOf("\\")).LastIndexOf("\\"));
reportpath += @"\VisitorIDReport.rpt"; //string reportpath = "D:\\Visitor Management System\\Visitor Management System\\VisitorIDReport.rpt";
RDT.Load(reportpath);
ConnectionInfo connectioninfo = new ConnectionInfo();
connectioninfo.DatabaseName = "ORCL";
connectioninfo.UserID = "itapps";
connectioninfo.Password = "it123";
Logindetailforreport(connectioninfo,RDT);
VisitorIDCrystalReportViewer.ReportSource = RDT;
RDT.SetDataSource(DTB);
}
And for exception i am not able to get any idea..
推荐答案
System.ArgumentOutOfRangeException：Length不能小于零。
参数名称：长度
System.ArgumentOutOfRangeException: Length cannot be less than zero.
Parameter name: length
我认为你在这一行搞乱了一些事情，纠正它。
I think you're messing something on this line, correct it.
string reportpath = System.Windows.Forms.Application.StartupPath.Substring(0,System.Windows.Forms.Application.StartupPath.Substring(0,System.Windows.Forms.Application.StartupPath.LastIndexOf("\\")).LastIndexOf("\\"));
2nd即使我点击继续它问我服务器用户名&密码
