Crystal Reports配置工具

Question

我有一个包含50个奇数子报表的Crystal报表,每个子报表都有大量参数.将其从一个数据库切换到另一个数据库需要很长时间,因为Crystal Reports IDE坚持要为每个子报表输入所有参数.

我想知道是否可以在C#中编写一个快速工具来查看rpt文件中所有子报告的当前数据库配置,理想情况下切换到不同的数据库.

不幸的是(或幸运的是)我对Crystal对象模型没有多少经验 - 任何人都知道从哪里开始？

谢谢,乔恩.

这应该做的工作.显然需要替换必要的密码和用户名.

Private Sub ProcessFile(ByVal FileName As String)
        Dim CR As Engine.ReportDocument = Nothing
        Try
            CR = New Engine.ReportDocument
            CR.Load(FileName, CrystalDecisions.Shared.OpenReportMethod.OpenReportByDefault)

            'Recurse thru Report
            RecurseAndRemap(CR)
            'Save File
            CR.SaveAs("OutPutFilePath")

        Catch ex As Exception
            MessageBox.Show(ex.Message)
        Finally
            If Not CR Is Nothing Then
                CR.Close()
                CR.Dispose()
            End If
        End Try
    End Sub

    Private Sub RecurseAndRemap(ByVal CR As Engine.ReportDocument)
        For Each DSC As CrystalDecisions.Shared.IConnectionInfo In CR.DataSourceConnections
            DSC.SetLogon("YourUserName", "YourPassword")
            DSC.SetConnection("YouServerName", "YourDatabaseName", False)
        Next

        CR.SetDatabaseLogon("YourUserName", "YourPassword")

        For Each Table As Engine.Table In CR.Database.Tables
            Table.LogOnInfo.ConnectionInfo.UserID = "YourUserName"
            Table.LogOnInfo.ConnectionInfo.Password = "YourPassword"
        Next

        If Not CR.IsSubreport Then
            For Each SR As Engine.ReportDocument In CR.Subreports
                RecurseAndRemap(SR)
            Next
        End If
    End Sub
