Why is this stopping?

I'm trying to write a tool to retrieve all my Outlook 2003 appointments for me.  At this point, I'm just in the start of a test tool.  I've got a form with a listbox on it named ListBox1 into which I want to add all these.  Once I have this working it's on to the next step.

I'm running the following and I'm being told I have > 1000 appointments (which I do).  However, when I run this I get through about a dozen and then it goes off into never land.  The thumbwheel on the ListBox shrinks to nothing and the program doesn't return.  It's appearently gotten into some sort of fatal loop (and yet I'm not getting any exception).

Any thoughts?  I'm just looking for some code that will list all the subjects of all my appointments.

        Dim oApp As Outlook.Application = New Outlook.Application()

        Dim oNS As Outlook.NameSpace = oApp.GetNamespace("mapi")
        oNS.Logon("YourValidProfile", Missing.Value, False, True)

        Dim oCalendar As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar)

        Dim oAppointments As Outlook.Items = oCalendar.Items

        MsgBox("Total : " & oAppointments.Count)

        ListBox1.Items.Clear()

        Dim oAppt As Outlook.AppointmentItem = Nothing

        oAppt = oAppointments.GetFirst

        Try

            While oAppt IsNot Nothing

                If Len(oAppt.Subject) = 0 Then

                    ListBox1.Items.Add("Nothing")

                Else

                    MsgBox(oAppt.Subject)

                    ListBox1.Items.Add(oAppt.Subject)

                    oAppt = oAppointments.GetNext

                End If

            End While

        Catch ex As Exception

            MsgBox(ex.Message & " " & ex.StackTrace)

        End Try

Here's the bug:

           While oAppt IsNot Nothing

                If Len(oAppt.Subject) = 0 Then

                    ListBox1.Items.Add("Nothing")
                    >>>>>>>>> If you get here, you are in an infinite loop since you never update the oAppt object like you do in the Else block.

                Else

                    MsgBox(oAppt.Subject)

                    ListBox1.Items.Add(oAppt.Subject)

>>>>>>>>>> You need to move this line OUTSIDE the If structure and you should be OK.
                    oAppt = oAppointments.GetNext

                End If

            End While

Well, I only had the one to add "nothing" in the event that I had an appointment with no subject, so that I'd have something show up.

Doh!  I see the point about the GetNext.  I'm stuck on a loop on an item with no subject.
