Crystal Reports exception

Guest

I am receiving the following exception randomly when printing crystal reports
via a print server application. The server will successfully print a random
number of an identical reports (report.rpt) and then for some reason, the
following exception is logged.

System.InvalidOperationException: Stack empty.
at System.Collections.Stack.Pop()
at SCRStartup.Leave()
at CrystalDecisions.CrystalReports.Engine.ReportObjects..ctor(SCRPrintJob
printJob, Int32 sectionCode)
at CrystalDecisions.CrystalReports.Engine.ReportObjects.GetEnumerator()
clsReports.LogInReport()

The code for LogInReport is as follows

Dim ret As Boolean = False
Dim repDoc As New ReportDocument
Dim subRepDoc As New ReportDocument
Dim crSections As Sections
Dim crSection As Section
Dim crReportObjects As ReportObjects
Dim crReportObject As ReportObject
Dim crSubReportObject As SubreportObject
Dim crDatabase As Database
Dim crTables As Tables
Dim crTable As Table
Dim crConnInfo As New ConnectionInfo
Dim crLogOnInfo As New TableLogOnInfo
Try
repDoc.Load(mstrFile, OpenReportMethod.OpenReportByDefault)

With crConnInfo
.ServerName = mstrServer
.DatabaseName = mstrDatabase
.UserID = mstrUserName
.Password = mstrPassWord
End With

'we iterate through the report database tables and log the user in
crDatabase = repDoc.Database
crTables = crDatabase.Tables
For Each crTable In crTables
crLogOnInfo = crTable.LogOnInfo
crLogOnInfo.ConnectionInfo = crConnInfo
crTable.ApplyLogOnInfo(crLogOnInfo)
Next

crSections = repDoc.ReportDefinition.Sections
For Each crSection In crSections
crReportObjects = crSection.ReportObjects
For Each crReportObject In crReportObjects
If crReportObject.Kind =
ReportObjectKind.SubreportObject Then
crSubReportObject = CType(crReportObject,
SubreportObject)
subRepDoc =
crSubReportObject.OpenSubreport(crSubReportObject.SubreportName)
crDatabase = subRepDoc.Database
crTables = crDatabase.Tables
For Each crTable In crTables
crLogOnInfo = crTable.LogOnInfo
crTable.LogOnInfo.ConnectionInfo = crConnInfo
crTable.ApplyLogOnInfo(crTable.LogOnInfo)
Next
End If
Next
Next
ret = True
Catch ex As Exception
EventLog.WriteEntry(AppName, ex.ToString, EventLogEntryType.Error)
End Try
Return ret

Any ideas?

TIA

This is an issue with Crystal running on dual processor machines. To resolve
the issue you have to bring up Task Manager, select your application, right
click and set affinity. Set your application up to run only on one CPU.

Hi OzSoft,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you're having a CR exception randomly.
If there is any misunderstanding, please feel free to let me know.

As far as I can see, this is a Crystal Report issue. I'm sorry but this
product is currently not supported by Microsoft. Besides posting here, you
can also check the Crystal Report technical support website for more
information. Please check the following KB article which will give you the
link for them.
