Creating Snapshots Passing Parameters with Reporting Services And Controlling Report History

Wayne Larimore — Wed, 13 Dec 2006 15:10:00 GMT

In order to pass parameters to a snapshot report in Reporting Services 2005 via WSDL you must create a linked report first. You can control the history a linked report keeps as well. Here's a code snippet I used recently to accomplish this...

''' Purpose:

''' Handles Creation Of Linked Reports in Microsoft SQL Server Reporting Services 2005

''' required parameters:

''' rs - reporting services web reference

''' reportname - name of linked report

''' rp - report path

''' rplr - report link path

Private Sub CreateLinkedReport(ByRef rs As ReportingService2005, ByVal reportname As String, ByVal rp As String, ByVal rplr As String)

Dim prop As New [Property]()

prop.Name = "Description"

prop.Value = "Linked Report for event code " & m_eventcd

Dim parms As ReportParameter() = Nothing

Dim reportParameterValues As New ArrayList

Dim value As New ParameterValue

value.Name = "EventCd"

value.Value = m_eventcd

value.Label = "EventCd"

reportParameterValues.Add(value)

parms = rs.GetReportParameters(rp & "/" & reportname, Nothing, True, reportParameterValues.ToArray(GetType(ParameterValue)), Nothing)

Dim props(0) As [Property]

props(0) = prop

Try

rs.CreateLinkedReport(reportname & "-" & m_eventcd, _

rplr, _

rp & "/" & reportname, _

props)

rs.SetReportParameters(rplr & "/" & reportname & "-" & m_eventcd, parms)

rs.SetReportHistoryLimit(rplr & "/" & reportname & "-" & m_eventcd, False, 5)

Catch ex As SoapException

ErrorMessageLabel.Text = "The creation of the linked report was not successful."

End Try

End Sub
