Thanks for your tips, Mark!
By looking at what win32com.client.dynamic._getitem_() does, and handling a
call in my invoke_item method, I was able to get the values of the cookie. I
haven’t ventured into _setitem_() yet, but at least this is a break-through and
hope this helps someone else on a similar path.
<% @Language="Python"%>

from win32com.client.dynamic import LCID
def invoke_item(self, index):
# partially taken from code in win32com.client.dynamic._getitem_()
if self.__dict__["_enum_"] is None:
self.__dict__["_enum_"] = self._NewEnum()
if self.__dict__["_enum_"] is not None:
invkind, dispid = self._find_dispatch_type_("Item")
if invkind is not None:
return self._get_good_object_(
self._oleobj_.Invoke(dispid, LCID, invkind, 1, index)
)
else:
return None
# don’t output anything in your ASP code prior to this or it will fail
Response.AddHeader("Set-Cookie", "MYCOOKIE=TYPE1=sugar&TYPE2=ginger+snap") #
correctly sets a cookie
for cookie in Request.Cookies:
# correctly reads the overall cookie --> TYPE2=ginger+snap&TYPE1=sugar
Response.Write(f" all cookie data = {Request.Cookies(cookie)}<BR><BR>")
# tells us there are 2 items in the cookie
Response.Write(f"cookie count = {Request.Cookies(cookie).Count}<BR><BR>")
# Shows "TYPE2"
Response.Write(f"cookie ITEM 1 =
{Request.Cookies(cookie).__getitem__(0)}<BR><BR>")
# Shows "TYPE1"
Response.Write(f"cookie ITEM 2 =
{Request.Cookies(cookie).__getitem__(1)}<BR><BR>")
# Shows "TYPE2"
Response.Write(f"cookie Key(1) = {Request.Cookies(cookie).Key(1)}<BR><BR>")
# Shows "TYPE1"
Response.Write(f"cookie Key(2) = {Request.Cookies(cookie).Key(2)}<BR><BR>")
testing = invoke_item(Request.Cookies(cookie), 1)
# Shows "ginger snap"
Response.Write(f"cookie TEST 1 using my special invoke_item =
{testing}<BR><BR>")
testing = invoke_item(Request.Cookies(cookie), 2)
# Shows "sugar"
Response.Write(f"cookie TEST 2 using my special invoke_item =
{testing}<BR><BR>")
this = Request.Cookies("THIS")
methods = ["AddRef", "GetTypeInfo", "GetTypeInfoCount", "HasKeys", "Invoke",
"Item", "Key", "QueryInterface"]
for method in methods:
invkind, dispid = this._find_dispatch_type_(method)
Response.Write(f" method dispatch type: {method} = {invkind},
{dispid}<BR><BR>")

Response.Write(f"DEFAULT DISPATCH NAME =

# displays all the methods/attributes of the object and helped me create the
“method” for loop above
Response.Write(f"this.__dir__() = {this.__dir__()}<BR><BR>")
Response.Write("DONE<BR>")

Thanks for the response!
Dir gives me this:
dir = ['AddRef', '_oleobj_', '__hash__', 'GetTypeInfo', '_username_',

'Item', '__getitem__', '__init_subclass__', '_UpdateWithITypeInfo_']
I’ll continue to play with the parameters!

I’m not sure if this is implemented or not in the Python ASP code or not, but I
am trying to duplicate some VBS code in Python, and use the URL below as a
primer as I couldn’t find any info on the internet about how Python might
implement this kind of ASP code.
I know the link is SUPER OLD but it’s the best docs I have been able to find on
the subject.

I am trying to create cookies similar to how the Microsoft Certificate
Authority Website on Windows Server 2016/2019/2022 does.
Here’s my Python ASP code
<% @Language="Python"%>
<%
Response.Write("Here<BR>")
for cookie in Response.Cookies:
Response.Write(Response.Cookies(cookie)["expires"])
Response.Write(f"dir = {Response.Cookies.__dir__()}")
if not "Type" in Response.Cookies:
cookie = Response.Cookies["type"] = "peanut-butter" # simplistic example of
trying to create one
Response.Write("Past Cookie Creation code<BR>")
%>
Here’s my error:
Python ActiveX Scripting Engine error '80020009'
Traceback (most recent call last): File "<Script Block >", line 3, in <module>
cookie = Response.Cookies["type"] = "peanut-butter" File
"C:\Python310\lib\site-packages\win32com\client\dynamic.py", line 348, in
__setitem__ self._oleobj_.Invoke(*allArgs), self._olerepr_.defaultDispatchName,
None COM Error: OLE error 0x80020101
/testcookies.asp, line 5
cookie = Response.Cookies["type"] = "peanut-butter"
Any guidance would be appreciated as I’ve scoured google for all it was worth.
Response.Cookies is "just" a dynamic COM object/collection and pywin32 has
never been great with them and "magic" things like properties etc due to
various semantic mismatches. If you are lucky, there might be a method on the
object taking 2 params? I'm guessing `__dir__` didn't help?
Regardless, a last resort would be to unwrap that __setitem__ call and
experiment with the correct "DISPATCH_*" flags (and in particular, trying
"DISPATCH_METHOD", because the examples are all showing function calls to "set"
a value, which python has no concept of!) - the other values are probably
correct.
HTH,
Mark
