我有一个outlook addin处理某种类型的已发送电子邮件。对于某种类型的电子邮件,用户必须填写包含一些信息的表单,然后应用程序将电子邮件作为MSG导出到文件系统中的目录树
我有一个带有按钮的功能区,该按钮为发送的电子邮件设置标记(userproperty),以便addin知道必须保存哪个电子邮件:
Private Sub Button1_Click(sender As Object, e As RibbonControlEventArgs) Handles Button1.Click
Dim oProperties As Outlook.UserProperties
Dim oProperty As Outlook.UserProperty
oMail = Globals.ThisAddIn.Application.ActiveInspector.CurrentItem
If Not oMail Is Nothing Then
oProperties = oMail.UserProperties
oProperty = oProperties.Add("SALVARAPIGES", Microsoft.Office.Interop.Outlook.OlUserPropertyType.olYesNo)
oProperty.Value = True
oMail.Save()
oMail.Send()
Else
MsgBox("Err")
Exit Sub
End If
End Sub
在插件启动中,我有(代码段):
Private Sub ThisAddIn_Startup() Handles Me.Startup
Dim sentItems As Outlook.Items
Dim sentFolder As Outlook.Folder
Dim paisapiges As String
Dim aux As String()
Dim ns As Microsoft.Office.Interop.Outlook.NameSpace
apigesIsLoaded = True
'adiciono um trigger para que sempre que for enviado um email e for do tipo SALVARAPIGES, ele fará o tratamento de salvar o email.
sentFolder = Application.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
sentItems = sentFolder.Items
AddHandler sentItems.ItemAdd, AddressOf itemadd
和我的itemadd例程:
Sub itemadd(ByVal NewEmailItem As Object)
Dim oProperties As Outlook.UserProperties
Dim salvaApiges As Boolean
Dim sentMessageItem As Outlook.MailItem = CType(NewEmailItem, Outlook.MailItem)
Dim mainForm As New formSalvarApiges()
salvaApiges = False
If Not sentMessageItem Is Nothing Then
oProperties = sentMessageItem.UserProperties
For Each pr As Outlook.UserProperty In oProperties
If pr.Name = "SALVARAPIGES" Then
salvaApiges = True
Exit For
End If
Next
If salvaApiges Then
mainForm.txtAssunto.Text = sentMessageItem.Subject
mainForm.sAction = "Acao01"
mainForm.sEntryId = sentMessageItem.EntryID
mainForm.ShowDialog()
mainForm.Close()
End If
End If
End Sub
正如您所看到的,只要电子邮件具有此“SALVARAPIGES”用户属性,就必须将其保存到目录树中的MSG。但有一半的用户说这不起作用(表格不是POPPED),但每当我测试它时,它都有效。我对VSTO及其背后的所有概念都很陌生......任何人都能指出方向吗?
我尝试过使用NameSpace.SendAndReceive方法,但他们一直在抱怨。
提前感谢!

引发事件的对象(sentItems)被声明为局部变量。一旦GC启动,它就会被释放,不会再引发任何事件。在类级别声明变量以确保它保持活动状态。

您需要在类级别声明源对象,以防止它被垃圾回收器滑动:
Dim sentItems As Outlook.Items
Private Sub ThisAddIn_Startup() Handles Me.Startup
Dim sentFolder As Outlook.Folder
Dim paisapiges As String
Dim aux As String()
Dim ns As Microsoft.Office.Interop.Outlook.NameSpace
apigesIsLoaded = True
'adiciono um trigger para que sempre que for enviado um email e for do tipo SALVARAPIGES, ele fará o tratamento de salvar o email.
sentFolder = Application.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
sentItems = sentFolder.Items
AddHandler sentItems.ItemAdd, AddressOf itemadd
