1661223 - Error: Invalid index - using Crystal Report SDK for Visual Studio .NET

Symptom

  • Attempting to retrieve objects from a report

For i = 0 To crReport.ReportDefinition.ReportObjects.Count
ReportType = crReport.ReportDefinition.ReportObjects(i).GetType.ToString
  • This results in the following error:

Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))

 

Environment

  • Crystal Reports for Visual Studio 2010
  • Visual Studion 2010

Reproducing the Issue

  1. Use the following code block:
Dim ReportType As String = vbNull
Dim ReportTypeCriteria As String = "CrystalDecisions.CrystalReports.Engine.FieldObject"
Dim crReport As CrystalDecisions.CrystalReports.Engine.ReportDocument = New CrystalDecisions.CrystalReports.Engine.ReportDocument
Dim i As Int32
Dim fieldobj As CrystalDecisions.CrystalReports.Engine.FieldObject = Nothing
CrystalReport.Equals(Server.MapPath("JobReport.rpt"))
CrystalReport.FileName = Server.MapPath("JobReport.rpt")
CrystalReportViewer1.ReportSource = Session("CrystalReportViewer.ReportSource")
CrystalReportViewer1.DataBind()

For i = 0 To crReport.ReportDefinition.ReportObjects.Count
    ReportType = crReport.ReportDefinition.ReportObjects(i).GetType.ToString
       If ReportType.Equals(ReportTypeCriteria) Then
           fieldobj = DirectCast(crReport.ReportDefinition.ReportObjects(i), CrystalDecisions.CrystalReports.Engine.FieldObject)
           With fieldobj.ObjectFormat
                        .EnableCanGrow = True
                        .HorizontalAlignment() = CrystalDecisions.Shared.Alignment.LeftAlign
          End With
      End If
Next

 

     2.    Run a report

     3.   The error will be thrown at the following line of code:

ReportType = crReport.ReportDefinition.ReportObjects(i).GetType.ToString

Cause

The index is set incorrectly:

For i = 0 To crReport.ReportDefinition.ReportObjects.Count

ReportType = crReport.ReportDefinition.ReportObjects(i).GetType.ToString

Resolution

  • Rather than using:
For i = 0 To crReport.ReportDefinition.ReportObjects.Count
  • Use:
For i = 0 To crReport.ReportDefinition.ReportObjects.Count - 1
