快速遍历 Outlook 约会项目 [英] Iterating quickly through Outlook appointment items

问题描述

我编写了一个宏，它遍历用户日历并对满足特定条件的条目进行修改.

I've written a macro which iterates through a users calendar and makes modifications to entries that fufil a certain critera.

问题是当日历很大时，这需要很长时间才能完成.我似乎无法过滤约会，因为 oAppointmentItems 似乎在创建条目时存储条目 - 这不一定与它们开始时的顺序相同.

The problem is that when the calendar is very big, this takes a long time to do. I don't seem to be able to filter the appointments because oAppointmentItems seems to store entries as they were created - which is not necessarily the same order as when they start.

我使用的代码是这样的:

The code I'm using is this:

Dim oOL As New Outlook.Application
Dim oNS As Outlook.NameSpace
Dim oAppointments As Object
Dim oAppointmentItem As Outlook.AppointmentItem

Set oNS = oOL.GetNamespace("MAPI")
Set oAppointments = oNS.GetDefaultFolder(olFolderCalendar)

For Each oAppointmentItem In oAppointments.Items

    DoEvents
    ' Something here
Next

Set oAppointmentItem = Nothing
Set oAppointments = Nothing
Set oNS = Nothing
Set oOL = Nothing

没有删除 DoEvents (这只意味着 Outlook 似乎锁定了用户)有没有什么方法可以通过应用某种过滤器来加快速度?例如，未来开始的约会.

Short of removing the DoEvents (which only means that Outlook appears to lock up to the user) is there any way I can speed this up by applying some kind of filter? For example, appointments which start in the future.

推荐答案

可以使用 Restrict 进行过滤.请注意，日期的格式为月、日、年，并且它们被过滤为字符串，即使存储为日期:

You can use Restrict to filter. Note that dates are in the format month, day, year and that they are filtered as strings, even though stored as dates:

Set olApp = CreateObject("Outlook.Application")
Set olNS = olApp.GetNamespace("MAPI")

Set olRecItems = olNS.GetDefaultFolder(olFolderTasks)
strFilter = "[DueDate] > '1/15/2009'"
Set olFilterRecItems = olRecItems.Items.Restrict(strFilter)


For i = 1 To olFilterRecItems.Count
  <...>
