SAP Crystal Reports中的数据库登录失败 [英] Database Login Failed In SAP Crystal Reports

问题描述

SAP Crystal Reports中的数据库登录失败

您好！

我正在使用vb.net 2010和SAP Crystal Reports进行项目。

关于报告，一切都很好，但我有一个不寻常的问题。

实际上我必须使用子报告技术进行报告，但是当我调用主报告调用另一个子报告时，Crystal Reports会给出错误数据库登录失败



我在下面显示主报告和子报告的代码。



子报告代码

Database Login Failed In SAP Crystal Reports
Hi !
I am working in a project using vb.net 2010 with SAP Crystal Reports.
Regarding the Reports everything is fine but i had an unusual problem.
Actually i have to make a report using sub report technique but when i call the main report that calls another sub report then Crystal Reports gives an error "Database Login Failed"

I show the code for both Master and sub report below.

"Code for Sub Report"

MyDataAdapter = New SqlDataAdapter("Select * From tbl_view_JC_SUP", SQL_CONNECTION)
MyDataAdapter.TableMappings.Add(0, "tbl_view_JC_SUP")
MyDataSet = New DataSet
MyDataAdapter.Fill(MyDataSet)
MyDataSet.Tables(0).TableName = "tbl_view_JC_SUP"
Dim MyCrystalReport As New rpt_CCC_JobCard_Sup
MyCrystalReport.SetDataSource(MyDataSet)

现在代码为Master报告

"Now Code for the Master Report"

MyDataAdapter = New SqlDataAdapter("Select * From tbl_view_JC_Master", SQL_CONNECTION)
MyDataAdapter.TableMappings.Add(0, "tbl_view_JC_Master")
MyDataSet = New DataSet
MyDataAdapter.Fill(MyDataSet)
MyDataSet.Tables(0).TableName = "tbl_view_JC_Master"
Dim MyCrystalReport As New rpt_CCC_JobCard
MyCrystalReport.SetDataSource(MyDataSet)
frm_r_ReportScreen.crvReportViewer.ReportSource = MyCrystalReport
frm_r_ReportScreen.Show()

注：

rpt_CCC_JobCard_Sup和rpt_CCC_JobCard是水晶报告。

rpt_CCC_JobCard_Sup是rpt_CCC_JobCard的子报告

当我调用主报告然后水晶报告错误来数据库登录失败

任何人都可以帮助我????

i非常担心！



谢谢！

Note:
"rpt_CCC_JobCard_Sup" and "rpt_CCC_JobCard" are the crystal reports.
rpt_CCC_JobCard_Sup is the sub report of rpt_CCC_JobCard
when i call the master report then crystal reports error comes "Database Login Failed"
can anyone help me ????
i am very worried !

thanks !
