Outlook加载项事件问题

您好，我正在使用VSTO 2005 SE创建outllok加载项。我正面临一个问题。我的展望事件没有被解雇。我也使用System Tray Icon类在任务栏中创建Icon。如果我评论创建托盘图标的代码，那么它工作正常。这是我的代码

Hello
  I am using VSTO 2005 SE for creating outllok add-in. I am facing a problem. My outlook events are not getting fired. I am also using System Tray Icon class for creating Icon in Task bar. If i comment the code for creating Tray Icon then it is working fine. Here is my code

    Public Class AddIn

    Private Sub ThisAddIn_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup
        Call initializeValue()
        Call initializeEvent()
        Call initializeTimer()

    Private Sub initializeValue()
        olApp = DirectCast(Application, Outlook.Application)
        olNS = olApp.GetNamespace("MAPI")
        olExplorer = olApp.ActiveExplorer
    End Sub
   
    Private Sub initializeEvent()
        Dim olFolder As Outlook.Folder = Nothing
        Dim olCalendarFolder As Outlook.MAPIFolder
        Dim olItems As Items
        olCalendarFolder = olNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar)
        olFolder = DirectCast(olCalendarFolder, Outlook.Folder)
        olItems = olCalendarFolder.Items

AddHandler olItems.ItemAdd，AddressOf ApptAdded
AddHandler olItems.ItemChange，AddressOf ApptModified
AddHandler olItems.ItemRemove，AddressOf ApptDelete
olFolder = Nothing
olCalendarFolder =无结束子

请大家告诉我为什么会这样？

      Public Sub loadTrayIcon()

          objValues(1) = My.Resources.icon2

          objValues(4) = My.Resources.icon5
          Call objTrayIcon.SetIconRange(objValues)
          objValues = Nothing
      End Sub
    End Module

Please can anyone tell me why this is happing?
