使用win32com设置属性

问题描述

我正在尝试自动创建一堆Outlook规则.我正在使用Python 2.7，win32com和Outlook2007.为此，我必须创建一个新的Rule对象并为其移动操作指定一个文件夹.但是，我无法成功设置Folder属性-尽管我提供了正确类型的对象，但它仍然保持None.

I'm trying to create a bunch of Outlook rules automatically. I'm using Python 2.7, win32com, and Outlook 2007. To do this I must create a new Rule object and specify a folder for its move action. However, I can't set the Folder property successfully -- it just stays None despite me giving an object of the right type.

import win32com.client
from win32com.client import constants as const

o = win32com.client.gencache.EnsureDispatch("Outlook.Application")
rules = o.Session.DefaultStore.GetRules()

rule = rules.Create("Python rule test", const.olRuleReceive)
condition = rule.Conditions.MessageHeader
condition.Text = ('Foo', 'Bar')
condition.Enabled = True

root_folder = o.GetNamespace('MAPI').Folders.Item(1)
foo_folder = root_folder.Folders['Notifications'].Folders['Foo']

move = rule.Actions.MoveToFolder
print foo_folder
print move.Folder
move.Folder = foo_folder
print move.Folder

# move.Enabled = True
# rules.Save()

打印

<win32com.gen_py.Microsoft Outlook 12.0 Object Library.MAPIFolder instance at 0x51634584>
None
None

我已经研究了在非动态模式下使用win32com时由makepy生成的代码.类_MoveOrCopyRuleAction在其_prop_map_put_字典中具有'Folder'的条目，但除此之外，我感到很困惑.

I've looked at the code generated by makepy when using win32com in non-dynamic mode. The class _MoveOrCopyRuleAction has an entry for 'Folder' in its _prop_map_put_ dict, but other than that I'm stumped.

推荐答案

使用comtypes.client代替win32com.client，您可以执行以下操作:

With comtypes.client instead of win32com.client you can do:

import comtypes.client

o = comtypes.client.CreateObject("Outlook.Application")
rules = o.Session.DefaultStore.GetRules()

rule = rules.Create("Python rule test", 0 ) # 0 is the value for the parameter olRuleReceive
condition = rule.Conditions.Subject # I guess MessageHeader works too
condition.Text = ('Foo', 'Bar')
condition.Enabled = True

root_folder = o.GetNamespace('MAPI').Folders.Item(1)
foo_folder = root_folder.Folders['Notifications'].Folders['Foo']

move = rule.Actions.MoveToFolder
move.__MoveOrCopyRuleAction__com__set_Enabled(True) # Need this line otherwise
                                                    # the folder is not set in outlook
move.__MoveOrCopyRuleAction__com__set_Folder(foo_folder) # set the destination folder

rules.Save() # to save it in Outlook

我知道不是win32com.client，也不是IronPython！

I know it's not with win32com.client, but not with IronPython either!
