问题描述
下午好，
我正在通过 Table 对象使用来自收件箱 + 子文件夹的所有电子邮件填充列表框。这工作正常。
然后，通过来自 Doubleclick 的 ListBox1 事件，我试图打开被选中的电子邮件。如果循环只通过收件箱文件夹，它是正确的。但是当我尝试从收件箱循环遍历子文件夹时，它不会。因此，我试图将收件箱 + 子文件夹中的所有电子邮件合二为一：
Set InBoxItems = SubFolder.Items
但除此之外它不起作用。可以做什么？
我的代码：
Option Explicit
Private Sub ListBox1_DblClick(ByVal Cancel As MSForms.ReturnBoolean)
Dim objNS As Outlook.namespace: Set objNS = GetNamespace("MAPI")
Dim oFolder As Outlook.MAPIFolder: Set oFolder = objNS.GetDefaultFolder(olFolderInBox)
Dim i As Long
Dim j As Long
Dim InBoxItems As Outlook.Items
Dim thisEmail As Outlook.MailItem
Dim SubFolder As Outlook.MAPIFolder
Dim myArray() As String
Dim Folders As New Collection
Dim entryID As New Collection
Dim StoreID As New Collection
Call GetFolder(Folders,entryID,StoreID,oFolder)
myArray = ConvertToArray(indexEmailInBox)
For j = 1 To Folders.Count
Set SubFolder = Application.Session.GetFolderFromID(entryID(j),StoreID(j))
Set InBoxItems = SubFolder.Items
Next
For i = LBound(myArray) To UBound(myArray)
If Me.ListBox1.Selected(i) = True Then
If TypeName(InBoxItems.Item(onlyDigits(myArray(i)))) = "MailItem" Then ' it's an email
'MsgBox onlyDigits(myArray(UBound(myArray) - i - 1))
Set thisEmail = InBoxItems.Item(onlyDigits(myArray(UBound(myArray) - i - 1)))
Unload Me
thisEmail.display
Exit Sub
End If
End If
Next i
End Sub
Function ConvertToArray(ByVal value As String)
value = StrConv(value,vbUnicode)
ConvertToArray = Split(Left(value,Len(value) - 1),"§")
End Function
Sub GetFolder(folders As Collection,entryID As Collection,StoreID As Collection,fld As MAPIFolder)
Dim SubFolder As MAPIFolder
folders.Add fld.FolderPath
entryID.Add fld.entryID
StoreID.Add fld.StoreID
For Each SubFolder In fld.folders
GetFolder folders,SubFolder
Next SubFolder
ExitSub:
Set SubFolder = nothing
End Sub
解决方法
您可以一次向一个集合中.Add 项。
Option Explicit ' Consider this mandatory
' Tools | Options | Editor tab
' Require Variable Declaration
' If desperate declare as Variant
Private Sub collection_Emails_Folder_And_Subfolders()
Dim objFolder As folder
Dim myItemsCol As New Collection
Dim i As Long
Dim myItems As Items
Set objFolder = Session.PickFolder
If objFolder Is Nothing Then
Exit Sub
End If
'Set objFolder = Session.GetDefaultFolder(olFolderInbox)
processFolder objFolder,myItemsCol
' Methods available are limited to:
' Add,Count,Item and Remove
Debug.Print vbCr & "Final total - myItemsCol.Count: " & myItemsCol.Count
' You may access item properties
For i = 1 To myItemsCol.Count
Debug.Print " " & i & ": " & myItemsCol(i).ReceivedTime,myItemsCol(i).subject
Next i
End Sub
Private Sub processFolder(ByVal objFolder As folder,ByVal myItemsCol As Collection)
' https://stackoverflow.com/questions/2272361/can-i-iterate-through-all-outlook-emails-in-a-folder-including-sub-folders
Dim EmailCount As Long
Dim myItem As Object
Dim myItems As Items
Dim i As Long
Dim oFolder As folder
Debug.Print vbCr & "objFolder: " & objFolder
EmailCount = objFolder.Items.Count
Debug.Print " EmailCount...: " & EmailCount
If EmailCount > 0 Then
Set myItems = objFolder.Items
myItems.Sort "[ReceivedTime]",False ' oldest to newest
For i = 1 To myItems.Count
'Debug.Print " " & i & ": " & myItems(i).ReceivedTime,myItems(i).subject
myItemsCol.Add myItems(i)
Next
End If
Debug.Print " Running total: " & myItemsCol.Count
If (objFolder.Folders.Count > 0) Then
For Each oFolder In objFolder.Folders
processFolder oFolder,myItemsCol
Next
End If
End Sub
您应该可以将 InboxItems 替换为 myItemsCol。
If TypeName(myItemsCol.Item((onlyDigits(myArray(i)))) = "MailItem" Then ' it's an email
Set thisEmail = myItemsCol.Item(onlyDigits(myArray(UBound(myArray) - i - 1)))
似乎您只需要遍历 Outlook 中的所有子文件夹即可获取每个文件夹的项目数。
Sub Test()
Set objOutlook = CreateObject( "Outlook.Application" )
Set objNamespace = objOutlook.GetNamespace( "MAPI" )
Set folders = objNamespace.DefaultStore.GetRootFolder().Folders
EnumFolders folders
End Sub
Dim counter as Long = 0
' recursively invoked function
Sub EnumFolders(folders)
For Each folder In folders
Debug.Print folder.FolderPath
Debug.Print folder.Count
counter = counter + folder.Items.Count
EnumFolders folder.Folders
Next
End Sub
