In fact, if a static wrapper has been built for the object
in question, the usual help (), inspect () stuff will
work, eg:
import win32com.client
#
# Make sure a proxy module is built behind-the-scenes
#
word = win32com.client.gencache.EnsureDispatch ("Word.Application")
help (word.__class__)
class _Application(win32com.client.DispatchBaseClass)
| Methods defined here:
|
| Activate(self)
|
| AddAddress(self, TagID=, Value=)
|
| AutomaticChange(self)
|
| BuildKeyCode(self, Arg1=, Arg2=, Arg3=, Arg4=)
|
| CentimetersToPoints(self, Centimeters=)
|
| ChangeFileOpenDirectory(self, Path=)
|
| CheckGrammar(self, String=)
[snip]
The only thing is that you can't always build a proxy
module. I'm never quite sure why or why not.

RE: Get all attributes of a com object
Hello,
you only get information about a COM object when you have a wrapper.
But you are using the dynamic invoke (Dispatch). So try the typelibrary
browser
in Pythonwin or use the generated wrapper with makepy or
gencache.EnsureDispatch.
But dir will give you only the methods and internal classes. The
properties
you get with OBJ._prop_map_get_.keys().

If I remember correctly (and its a while since I did this), you may be able to use win32com/client/makepy.py to generate a .py file from a type library. If you do this then the python wrapper will have methods to forward the calls, so you can inspect it as above. Unfortunately, not all COM objects have to have type libraries, so it isn't always possible to do this and then you have to fall back on reading the documentation for whatever COM object you are using. You can also embed a call to gencache.EnsureModule() into your code to generate the needed wrappers automatically: the output from makepy tells you this. The easy way to run makepy is to run PythonWin and use 'COM makepy utility' from its tool menu. Then all you have to do is figure out which of the type libraries in the system is the relevant one. -- http://mail.python.org/mailman/listinfo/python-list

Really ?
def dump(obj):
for name in dir(obj):
print getattr(obj, name)

Re: Get all attributes of a com object
Thanks for your tips.
But dir() and inspect did not really help.
dir():
['GetIDsOfNames', 'GetTypeInfo', 'GetTypeInfoCount', 'Invoke',
'InvokeTypes', 'QueryInterface', '_ApplyTypes_', '_FlagAsMethod',
'_LazyAddAttr_', '_NewEnum', '_Release_', '__AttrToID__',
'__LazyMap__', '__call__', '__cmp__', '__doc__', '__getattr__',
'__getitem__', '__init__', '__int__', '__len__', '__module__',
'__nonzero__', '__repr__', '__setattr__', '__setitem__', '__str__',
'_builtMethods_', '_enum_', '_find_dispatch_type_',
'_get_good_object_', '_get_good_single_object_', '_lazydata_',
'_make_method_', '_mapCachedItems_', '_oleobj_', '_olerepr_',
'_print_details_', '_proc_', '_unicode_to_string_', '_username_',
'_wrap_dispatch_']
pprint.pprint(inspect.getmembers(objDom)):
[('GetIDsOfNames',
),
('GetTypeInfo',
),
('GetTypeInfoCount',
),
('Invoke', ),
('InvokeTypes',
),
('QueryInterface',
>>),
('_ApplyTypes_',
>>),
...
Further more this nice method also did not know any more:
objDom._print_details_():
AxDispatch container Dispatch wrapper around
Methods:
Props:
Get Props:
Put Props:
Any additional hint ?
Could it be, that you must know in advance, what to ask a com object;
so there is no dump possibility ?
Thanks

Look at dir() and the inspect module.

Get all attributes of a com object
Without to know the names, is it possible to dump all attributes of a
com object?
from win32com.adsi import *
objDom = ADsOpenObject("LDAP:/ ...
print ???"all attributes"??? of objDom
Thanks
