Retrieving client account properties for data processing

Hi guys,

I have a company project I need completed and I am very new to network VB programming and could use help. I have been given an already existing company ASP Annual Leave system from which I need to add classes involving Outlook Calendar Automation. I have already designed/tested the Outlook Automation code on a local, non-server level and it worked fine. My challenge is tweaking that code to retrieve a specific account detail from a company user who has requested A/L via the system and approved by manager. I understand this sounds very complex and may take time and alot of replies to get sorted but I'd be grateful for your help. One class code I have for Outlook Automation is adding calendar appointments as shown below:

Code:

---

Public Sub AddOutlookAppointment()
            Dim oOutlook As New Outlook.Application
            Dim oOutlookNamespace As Microsoft.Office.Interop.Outlook.NameSpace = oOutlook.GetNamespace("MAPI")
            Dim oAppItem As Outlook.AppointmentItem = oOutlook.CreateItem(OlItemType.olAppointmentItem)
            Dim startDate As Date = CDate(StartDate1.Text)
            Dim endDate As Date = CDate(EndDate1.Text)


            oAppItem.Subject = "Annual Leave"

            oAppItem.Start = startDate
            oAppItem.End = endDate

            oAppItem.ReminderSet = True

            oAppItem.BusyStatus = Outlook.OlBusyStatus.olOutOfOffice


            Marshal.FinalReleaseComObject(oOutlookNamespace)
            oOutlookNamespace = Nothing
            oAppItem.Save()
            Marshal.FinalReleaseComObject(oAppItem)
            oAppItem = Nothing

            oOutlook.Quit()
            Marshal.FinalReleaseComObject(oOutlook)
            oOutlook = Nothing

            'Cleanup
            GC.Collect()
            GC.WaitForPendingFinalizers()
            GC.Collect()
            GC.WaitForPendingFinalizers()

        End Sub

Thanks.
