将项目视为邮件项目 [英] Treating Item As MailItem
问题描述
我正在 Outlook 2016 中创建 VBA 应用程序.它分析传入的电子邮件并使用其主题行来搜索重复(或接近重复)的主题行.我使用 for-each 循环来浏览项目列表(收件箱中的电子邮件)并分析每个项目的标准.
I am creating an VBA application in Outlook 2016. It analyzes an incoming email and takes its subject line to search for duplicate (or close to duplicate) subject lines. I use a for-each loop to go through a list of Items (which are emails within the inbox) and analyze each one for the criteria.
一旦需要回复,收到的电子邮件和重复的电子邮件都会被标记,以表明我已经回复了它们.
Once a response is required, both the incoming email and the duplicate email are flagged so show that I have already responded to them.
我知道 Item 和 olItem 都应该是 Item 对象.我遇到的问题是:
I know both Item and olItem should both be Item objects. The problem I am having is in the line:
If InStr(1, GetPreceedingSubject(olItem.Subject), GetPreceedingSubject(SubjectString)) <> 0 _
And olItem.FlagRequest <> "Follow up" Then
它给了我错误
运行时错误‘438’:对象不支持此属性或方法"
"Run-time error '438': Object doesn't support this property or method"
我知道它是 olItem,因为它是我在出现错误之前更改的唯一函数部分.这让我觉得很奇怪,因为以下代码段仍然有效:
I know it is the olItem because it is the only part of the function that I had changed before I got the error. This strikes me as odd because the following snippet still works:
' flag both the emails that prompted the response
With Item
' due this week flag
.MarkAsTask olMarkThisWeek
' sets a specific due date
.TaskDueDate = Now + 3
.FlagRequest = "Follow up"
.FlagStatus = 2
.ReminderSet = False
.Save
End With
With olItem
' due this week flag
.MarkAsTask olMarkThisWeek
' sets a specific due date
.TaskDueDate = Now + 3
.FlagRequest = "Follow up"
.FlagStatus = 2
.ReminderSet = False
.Save
End With
所以在第一个代码片段中,它似乎将 olItem 视为一个对象,但在下一个代码片段中,它允许我将其视为 MailItem 对象.有什么建议?我已经查找了从 Item 转换为 MailItem 的方法,即使只是暂时用于那行代码,但显然无济于事.完整的子程序如下:
So in the first code snippet, it appears that it is treating the olItem as an object, but in the next one it allows me to treat it like a MailItem object. Any suggestions? I have looked up ways to cast from Item to MailItem, even just temporarily for that line of code, but obviously to no avail. Full subroutine below:
Private Sub myOlItems_ItemAdd(ByVal Item As Object)
If ParsingEnabled = False Then
Exit Sub
End If
Dim SubjectString As String ' tracks the control word to search the subject line for
Dim pingCount As Integer ' tracks the number of copies found.
Dim TimeDiff As Double
Dim Protocol As Variant
Dim FlagStatus As Integer
pingCount = 0
SubjectString = Item.Subject ' searches subject line for this word
' If the email is a read receipt, then move it to a different folder
If TypeName(Item) = "ReportItem" Then
NullPrompt = MoveFolders(Item, "Read")
If NullPrompt >= 0 Then
setLblDebug ("Read receipt: " & Mid(SubjectString, 7, Len(SubjectString)))
Item.UnRead = False
Else
NullPrompt = setLblDebug("Error when moving read receipt. Please check inbox and correct", lngRed)
End If
End If
' Check to make sure it is an Outlook mail message, otherwise
' subsequent code will probably fail depending on what type
' of item it is.
If TypeName(Item) = "MailItem" Then
' display the message
setLblDebug ("Incoming Message: " & Item.Subject)
Item.UnRead = False ' mark message as read
' Iterate through each item of the list
For Each olItem In myOlItems
If InStr(1, GetPreceedingSubject(olItem.Subject), GetPreceedingSubject(SubjectString)) <> 0 _
And olItem.FlagRequest <> "Follow up" Then
Protocol = ProtocolCode(Item.Subject)
If Protocol(0) <> 0 Then
' Time difference between the 2 emails
TimeDiff = (Item.ReceivedTime - olItem.ReceivedTime) * 24 ' Gives the hour difference
' If time difference is 0, then it is the same email
If Protocol(0) >= TimeDiff And TimeDiff <> 0 Then
' flag both the emails that prompted the response
With Item
' due this week flag
.MarkAsTask olMarkThisWeek
' sets a specific due date
.TaskDueDate = Now + 3
.FlagRequest = "Follow up"
.FlagStatus = 2
.ReminderSet = False
.Save
End With
With olItem
' due this week flag
.MarkAsTask olMarkThisWeek
' sets a specific due date
.TaskDueDate = Now + 3
.FlagRequest = "Follow up"
.FlagStatus = 2
.ReminderSet = False
.Save
End With
' email and call if required
RenderMail (olItem)
If Protocol(1) = 1 Then
NullPrompt = RenderCallPrompt(olItem.Subject, Item.ReceivedTime)
End If
' set the debug prompt message
NullPrompt = setLblDebug("Response Made: " & Item.Subject & " [" & Item.ReceivedTime & "]", lngBlue)
If True Then Exit For ' Reponse made, stop looking for additional emails
End If
End If
End If
Next olItem
End If
End Sub
推荐答案
您不能将不是 MailItem 的 Object 视为 MailItem.
You cannot treat an Object which is not a MailItem as a MailItem.
MailItem 是 Object 的子集.对象包括 TaskItem、AppointmentItem 等.
MailItem is a subset of Object. Object encompasses TaskItem, AppointmentItem and others.
其他类型不一定具有 MailItem 的属性.
Other types will not necessarily have the properties of a MailItem.
在您的代码中:
' Check to make sure it is an Outlook mail message, otherwise
' subsequent code will probably fail depending on what type
' of item it is.
If TypeName(Item) = "MailItem" Then
添加相同的测试以确保 olItem 是 MailItem.
Add the same test to ensure olItem is a MailItem.
For Each olItem In myOlItems
' Check to make sure it is an Outlook mail message, otherwise
' subsequent code will probably fail depending on what type
' of item it is.
If TypeName(olItem) = "MailItem" Then
'
End If
Next olItem
