BOEXI3.1 SDK with Visual studio 2005

20 Views

Hi,

I am writing a simple application on BOEXI3.1 using visual studio .net 2005. with the below code.

Imports CrystalDecisions.Enterprise

Imports System.Web.Security

Partial Class _Default

Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim mySessionMgr As New SessionMgr()

Dim myEnterpriseSession As EnterpriseSession

Dim myInfoStore As InfoStore

Dim myEnterpriseService As EnterpriseService

Try

myEnterpriseSession = mySessionMgr.Logon("administrator", "mypwd", "myserver", "SecEnterprise")

Catch ex As Exception

Throw New Exception("Sorry - You could not be logged on. " & ex.Message)

End Try

myEnterpriseService = myEnterpriseSession.GetService("InfoStore")

myInfoStore = New InfoStore(myEnterpriseService)

Session("InfoStore") = myInfoStore

Session("EnterpriseSession") = myEnterpriseSession

End Sub

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim sInfostoreSQL As String = "select * from ci_infoobjects where si_kind='Webi' and SI_Instance=0"

Dim myInfoStore As InfoStore = CType(Session("InfoStore"), InfoStore)

Dim myInfoObjectsReports As InfoObjects

Try

myInfoObjectsReports = myInfoStore.Query(sInfostoreSQL)

Catch ex As Exception

Throw New Exception("Error in Fetching Report Instances" & ex.Message)

End Try

Dim myinfoobject As InfoObject

For Each myinfoobject In myInfoObjectsReports

Dim str As String

str = myinfoobject.Title

Next

End Sub

End Class

This code run fine first time. Second time when I click on button again I get below error.

I am getting error.

Attempted to read or write protected memory. This is often an

indication that other memory is corrupt

This error seems to be generated by

CrystalDecisions.Enterprise.InfoStore.dll. I tried to view in the

output window and find below is the message into that.

A first chance exception of type 'System.AccessViolationException'

occurred in CrystalDecisions.Enterprise.InfoStore.dll.

I can see some more information in the output window.

Same code is working fine with BOEXIR2. I tried building BOEXI3.1 machine with FP1.3 as well.

Also tested with multple patches of Visual studio. Tried to deploy the code to IIS6.0 still same result.

I am not doing anything complex. It's simple infoobjects retrieval and reuse the session thing.

Any help on this will be appreciated.

Thanks,

Abhay
