从Word.Application对象获取Document对象时，其成员不会从gencache缓存中填充，而VBSEdit能够获取它们的成员 [英] When getting Document object from Word.Application object, its members are not filled from gencache cache while VBSEdit is able to get them

问题描述

https://mail.python.org/pipermail /python-win32/2004-October/002582.html 完美地总结了我的问题(只需进行一些修改即可针对我的情况进行更新)

https://mail.python.org/pipermail/python-win32/2004-October/002582.html summarizes my problem perfectly (with slight edits to update it for my case):

我想拥有一个包含所有方法的Word Document实例， 互动会话期间可见的属性.这是我的currnet 方法:

I would like to have a Word Document instance with all methods and properties visible during interactive session. This is my currnet apporach:

>>> from win32com.client import gencache, Dispatch
>>> gencache.EnsureModule('{00020905-0000-0000-C000-000000000046}', 0, 8, 1, bForDemand=True) 
<module 'win32com.gen_py.00020905-0000-0000-C000-000000000046x0x8x1' from
'C:\DOCUME~1\osuchw\LOCALS~1\Temp\gen_py\2.3\00020905-0000-0000-C000-000000000046x0x8x1\__init__.py'>
>>> word = Dispatch('Word.Application')
>>> word 
<win32com.gen_py.Microsoft Word 12.0 Object Library._Application instance at 0x18074720>
>>> doc = word.Documents.Add()
>>> doc 
<win32com.gen_py.None.Document>

如您所见，我正在获取一个不知道其动态对象的对象 方法/属性.我想得到的是这样的:

As you can see I am getting a dynamic object not knowing its methods/properties. What I would like to get is something like:

>>> doc = Dispatch('Word.Document')
>>> doc 
<win32com.gen_py.Microsoft Word 12.0 Object Library._Document instance at 0x37038040>

我想我还需要从另一个类型库(例如，有"Office 12.0 Object Library")生成包装器，但是没有关于它的提示.同样，在HKEY_CLASSES_ROOT\CLSID\{00020906-0000-0000-C000-000000000046}上也没有TypeLib子项，这是doc.CLSID产生的.

I guess I need to also generate a wrapper from another type library (e.g. there is "Office 12.0 Object Library") but there's no hint on which it is. Likewise, there's no TypeLib subkey at HKEY_CLASSES_ROOT\CLSID\{00020906-0000-0000-C000-000000000046} which is what doc.CLSID produces.

该线程中的唯一答案是直接向RTFM咨询有关Word编程的通用书籍，没有任何提示(我非常怀疑它甚至提到了类型库).

The only answer in that thread directs to RTFM a general book on Word programming w/o any hints whatsoever (I seriously doubt it even mentions typelibs).

我最终使用以下代码为计算机上的所有类型库生成了包装器:

I ended up generating wrappers for all the type libraries at the machine with the following code:

import win32com.client.selecttlb    
ii=win32com.client.selecttlb.EnumTlbs()
ii=[i.desc for i in ii]
# one typelib - "Visual Basic runtime objects and procedures [6.0]" - produced an error
for i in ii: subprocess.call(['python','-m','win32com.client.makepy',i])

但是即使在这种情况下，它仍然是win32com.gen_py.None.Document.

but even in this case, it's still win32com.gen_py.None.Document.

最奇怪的是，对象的类 被识别并存在于缓存中:

The strangest thing is that the object's class is recognized and present in the cache:

>>> ad=win32com.client.gencache.EnsureDispatch("Word.Document")
>>> d = w.ActiveDocument
>>> d.__class__
<class win32com.gen_py.00020905-0000-0000-C000-000000000046x0x8x4.Document at 0x02A101B8>
>>> ad.__class__
<class win32com.gen_py.00020905-0000-0000-C000-000000000046x0x8x4._Document at 0x02A07B20>
>>> len(dir(ad.__class__))
141
>>> len(dir(d.__class__))
11

与此同时，VBA编辑器和 VBSEdit 列出了w.ActiveDocument的成员.他们怎么做到的?为什么pythoncom不能做到同样的事情?

At the same time, VBA editor and VBSEdit list w.ActiveDocument's members just fine. How do they do that and why can't pythoncom do the same?

推荐答案

d._dispobj_具有所有成员，因此可以代替d使用.

d._dispobj_ has all the members, so it can be used instead of d.

眼前的问题解决了.

但是我还是不知道发生了什么事.

Yet I've still no idea what is going on.
