仅针对某些 Outlook 宏触发 ItemSend

Question

如何修改下面的代码来触发myMailItem_ItemSend事件，只有当邮件是myMacro1发送的，而其他情况下（比如myMacro2）不触发？

应该特别为那些使用 myMailItem 对象的宏触发事件。

Public WithEvents myMailItem As Outlook.MailItem

Public Sub Initialize_handler() 
    Set myMailItem = Outlook.MailItem
End Sub 

Private Sub myMailItem_ItemSend(ByVal Item As Object, Cancel As Boolean) 
    Dim prompt As String 
    prompt = "Are you sure you want to send " & Item.Subject & "?" 
    If MsgBox(prompt, vbYesNo + vbQuestion, "Send confirmation") = vbNo Then 
        Cancel = True 
    End If 
End Sub

'Should trigger the send confirmation msgbox
Private Sub myMacro1()
    Dim objApp As Outlook.Application
    Set objApp = Application
    Set myMailItem = objApp.ActiveInspector.CurrentItem.ReplyAll
    myMailItem.Display
End Sub

'Should NOT trigger the send confirmation msgbox
Private Sub myMacro2()
    Dim objApp As Outlook.Application
    Set objApp = Application
    Dim oEmail As Outlook.mailItem
    Set oEmail = objApp.ActiveInspector.CurrentItem.ReplyAll
    oEmail.Display
End Sub

我们将不胜感激。

我会这样做：

1. 在您的模块中定义一个全局变量，例如Dim TriggerMsgBox As Boolean。默认情况下，该变量将为 false。
2. 在myMacro1() 中将其初始化为True。只有在这种情况下，它才会变成True。否则，它将是False。
3. 在myMailItem_ItemSend事件中使用：如果变量是True（意思是我们刚刚经过myMacro1()），那么需要提示MsgBox。否则，您将只是路过。当然，不要忘记在MsgBox 被命中后将变量重置为False，否则您将在以后继续显示它。

在你的代码中是：

Public WithEvents myMailItem As Outlook.MailItem
Dim TriggerMsgBox As Boolean '<-- NEW LINE OF CODE

Public Sub Initialize_handler() 
    Set myMailItem = Outlook.MailItem
End Sub 

Private Sub myMailItem_ItemSend(ByVal Item As Object, Cancel As Boolean) 
    Dim prompt As String 
    If TriggerMsgBox Then '<-- NEW LINE OF CODE
        TriggerMsgBox = False '<-- NEW LINE OF CODE
        prompt = "Are you sure you want to send " & Item.Subject & "?" 
        If MsgBox(prompt, vbYesNo + vbQuestion, "Send confirmation") = vbNo Then 
            Cancel = True 
        End If
    End If '<-- NEW LINE OF CODE
End Sub

'Should trigger the send confirmation msgbox
Private Sub myMacro1()
    Dim objApp As Outlook.Application
    Set objApp = Application
    Set myMailItem = objApp.ActiveInspector.CurrentItem.ReplyAll
    TriggerMsgBox = True '<-- NEW LINE OF CODE
    myMailItem.Display
End Sub

'Should NOT trigger the send confirmation msgbox
Private Sub myMacro2()
    Dim objApp As Outlook.Application
    Set objApp = Application
    Dim oEmail As Outlook.mailItem
    Set oEmail = objApp.ActiveInspector.CurrentItem.ReplyAll
    oEmail.Display
End Sub
