Dear Aspose-Team,

we are evaluating your Networking-Components.

We want to fetch e-Mails from an exchange server,
Unfortunately we are getting exceptions from your component:

Object Reference not set to an instance:

{"Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt."}
    System.NullReferenceException: {"Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt."}
    Data: {System.Collections.ListDictionaryInternal}
    HelpLink: Nothing
    InnerException: Nothing
    Message: "Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt."
    Source: "Aspose.Network"
    StackTrace: "   bei Aspose.Network.xb48d0c971e5c9051.get_Length()    bei Aspose.Network.xb48d0c971e5c9051.Read(Byte[] buffer, Int32 offset, Int32 count)    bei Aspose.Network.x465598d3637eaed7.x3ad8e53785c39acd(Stream x50a18ad2656e7181, Stream x6b8e154b42d5c1e3)    bei Aspose.Network.Imap.ImapClient.SaveMessage(String uniqueId, Stream output)    bei Aspose.Network.Imap.ImapClient.SaveMessage(String uniqueId, String fileName)    bei IMAP_Queue_Aspose.getMailQueue(Collection& inQueue, XmlDocument objXML, String strLicencePath) in C:\IMAP\E-MAIL-SERVICETEST-IMAP\E-MAIL-SERVICETEST-IMAP\Modules\IMAP_Queue_ASPOSE.vb:Zeile 123."
    TargetSite: {System.Reflection.RuntimeMethodInfo}


This is the code we are using:

Do While i < list.Count
                            'save the eml file locally
                            Try
                                objASPOSEIMAP.SaveMessage(list(i).UniqueId, "c:\temp\" & list(i).UniqueId & ".eml")
                                i += 1

                                'Threading.Thread.Sleep(100)
                                'Application.DoEvents()

                            Catch ex As Exception
                                Stop
                            End Try
 Loop

If we uncomment the Sleep-Statement then it works ...

Kind regards,

Peter

Hi Peter,

1. Could you please tell me what version of Aspose.Network are you using?

2. You are running on .NET 2.0 or .NET 3.5?

3. What exchange server version?

thanks,
