VB.NET, App - How can i close an Outlook Item?

[chrisli]

Hey,
i have written this code to read all Outlook Appointments from another user and fill them into my DGV.

Public Sub ReadOtherUserAppointment(ByVal UserName As String)
        Dim objolApp As New Outlook.Application
        Dim objNS As Outlook.NameSpace
        Dim objRecip As Outlook.Recipient
        Dim objFolder As Outlook.MAPIFolder
        objNS = objolApp.GetNamespace("MAPI")
        objRecip = objNS.CreateRecipient(UserName)
        objRecip.Resolve()
        Dim i As Integer = 0

            If objRecip.Resolved Then
                objFolder = objNS.GetSharedDefaultFolder(objRecip, Outlook.OlDefaultFolders.olFolderCalendar)

                For x As Integer = 1 To objFolder.Items.Count
                        If objFolder.Items.Item(x).categories = "Urlaub" Then
                        dgv.Rows.Add()
                        dgv.Item("clmstart", i).Value = objFolder.Items.Item(x).start
                        dgv.Item("clmend", i).Value = objFolder.Items.Item(x).end
                        dgv.Item("clmsubject", i).Value = objFolder.Items.Item(x).subject
                        dgv.Item("clmcategory", i).Value = objFolder.Items.Item(x).categories
                        i = i + 1
                    End If
objFolder.Items.Item(x).Close(Outlook.OlInspectorClose.olDiscard)                   
 Next

            End If

Now when i read the appointments and fill them into my DataGridView there is an Error after some items:
System.Runtime. InteropServices .COMException (0x80040305): Your server administrator has limited the number of items you can open simultaneously. ..

I tried objFolder.Items .Item(x).Close( Outlook.OlInspe ctorClose.olDis card), but this gievs me the error:
System.Runtime. InteropServices .COMException (0x8002000F) Parameter not optional...

Any ideas?

Greetings

I found a solution :)

After i went through every Item i do this:

If objRecip.Resolved Then
objFolder = objNS.GetSharedDefaultFolder(objRecip, Outlook.OlDefaultFolders.olFolderCalendar)

For x As Integer = 1 To objFolder.Items.Count

'Same code as above...

End If            

'Quit the Session when every item is added.
        
objolApp.Quit()

'Run garbagecollector

GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
GC.WaitForPendingFinalizers()
Next
End If

Simple, huh? :)

Sorry for my bad english.
