Crystal Reports Viewer to handle multiple reports

[Bufedog]

I have created a crystal reports viewer that handles multiple reports, but I have not been able to figure out how to pass the report objects as a parameter in the method. If I want to pass different types of report objects, what is the abstraction?

I want to create a method that accepts as a parameter a crystal report object. This crystal report object will be the reportsource for the viewer. How do I abstract to accept different reports as the parameter?

I'm not sure I have enough information to give you the best answer. There are several way to skin this cat. In the past I set up a string variable to hold a short name of the report selected. Then when it comes time to fill the report viewer, I use a Case/Select or 'IF' statements based on that string.

        If RepString = "MonthlyAcc" Then
            Dim MyReport As New MonthlyReportName
            MyReport.SetParameterValue("ParameterName", ParmValue)
        Else
            If RepString = "YearlyAcc" Then
                Dim MyReport As New YearlyReportName2
                MyReport.SetParameterValue("ParameterName", ParmValue)
            End If
        End If
        CRviewer1.ReportSource = MyReport

or this way...

        Select Case RepString
            Case "MonthlyAcc"
                Dim MyReport As New MonthlyReportName
                MyReport.SetParameterValue("ParameterName", ParmValue)
            Case "YearlyAcc"
                Dim MyReport As New YearlyReportName2
                MyReport.SetParameterValue("ParameterName", ParmValue)
            Case Else
                  'Statements executed if  no Case value is = variable
        End Select
        CRviewer1.ReportSource = MyReport

If that isn't what you want, let me know...

Sorry I've been so long in replying. I finally go this to work by establishing a property that was a ReportDocument object. I passed the reportdocument object to the display form and it worked fine.
