使用 VBA 检索截断的 Outlook 电子邮件标头 [英] Truncated Outlook email headers retrieved using VBA

问题描述

我想访问 Outlook 2010 中的电子邮件标头.我使用下面的代码，但不幸的是结果只包含标题的前 252 个字符.对我做错了什么有什么建议吗?

I want to access the email headers in Outlook 2010. I use the code below but unfortunately the result contains only the first 252 characters of the header. Any suggestion on what I'm doing wrong?

Dim strHeader As String
strHeader = GetInetHeaders(olItem)
MsgBox "Truncated string: " & strHeader 

和

Function GetInetHeaders(olkMsg As Outlook.MailItem) As String
    ' Purpose: Returns the internet headers of a message.'
    ' Written: 4/28/2009'
    ' Author:  BlueDevilFan'
    ' Outlook: 2007'
    Const PR_TRANSPORT_MESSAGE_HEADERS = "http://schemas.microsoft.com/mapi/proptag/0x007D001E"
    Dim olkPA As Outlook.PropertyAccessor
    Set olkPA = olkMsg.PropertyAccessor
    GetInetHeaders = olkPA.GetProperty(PR_TRANSPORT_MESSAGE_HEADERS)
    Set olkPA = Nothing
End Function

推荐答案

Msgbox 不是证明截断的好方法.文本可以被合法地截断.

Msgbox is not a good method of proving truncation. Text can be legitimately truncated.

邮件项目中的文本似乎没有被截断.至少我没有注意到切断信息.

Text in a mailitem does not appear to be truncated. At least I do not notice cut off information.

Private Sub Test_GetInetHeaders()

Dim olNewmail As mailItem
Dim strHeader As String
Dim olItem As mailItem

Set olItem = ActiveInspector.currentItem
strHeader = GetInetHeaders(olItem)

Set olNewmail = CreateItem(olMailItem)
olNewmail.body = strHeader
olNewmail.Display

MsgBox "Truncated string if limit exceeded: " & strHeader

ExitRoutine:
    Set olItem = Nothing
    Set olNewmail = Nothing

End Sub

Function GetInetHeaders(olkMsg As outlook.mailItem) As String
    ' Purpose: Returns the internet headers of a message.'
    ' Written: 4/28/2009'
    ' Author:  BlueDevilFan'
    ' Outlook: 2007'
    Const PR_TRANSPORT_MESSAGE_HEADERS = "http://schemas.microsoft.com/mapi/proptag/0x007D001E"
    Dim olkPA As outlook.propertyAccessor
    Set olkPA = olkMsg.propertyAccessor
    GetInetHeaders = olkPA.GetProperty(PR_TRANSPORT_MESSAGE_HEADERS)
    Set olkPA = Nothing
End Function
