Hi,
I am trying to use the function "CreateStreamOn HGlobal" from python code
(I need to pass an IStream object to MSXML, like I do in C++ code).
I was able to retrieve a pointer on the IStream object in this way:
from ctypes import *
stream = c_int()
windll.ole32.Cr eateStreamOnHGl obal(c_long(0), c_long(1), byref(stream))
print "%x"%stream.val ue
The problem is that I would like to attach this pointer to a python
IDispatch object (in Python only, not using a C++ DLL to do the stuff).
Do you know a way to do it ?
Thanks for your attention. 3 2779

What do you want to do with this pointer? Pass it to a function called
via ctypes?

Once it is a IDispatch object (like the IDispatch object returned by
"win32com.clien t.Dispatch"), I will call the IStream methods on it and
pass it to a DOMDocument of MSXML. It should look like that:
stream = c_int()
windll.ole32.Cr eateStreamOnHGl obal(c_long(0), c_long(1), byref(stream))
stream_obj = some_conversion (stream)
# IDispatch call
stream_obj.Writ e("some data", 9)
doc = win32com.client .Dispatch("MSXM L2.DOMDocument. 4.0")
doc.load(stream _obj)

I am working with the MSHTML editor control. I used

I have just implemented some of the necessary custom COM

I'm a js newbie trying to use some very simple js to call an ActiveX
object's methods.
I need to use a pointer to call an embedded ActiveX object's method to
receive a number.
As I understand it, js is typeless so how can I get a variable to be a
pointer type?
Passing var i as the parameter gets an undefined value in return.
Thanks IA, Simon

Controlling Download and Execution
The WebBrowser Control gives you control over what it downloads, displays,

IDispatch so it handles DISPID_AMBIENT_DLCONTROL. When the WebBrowser
Control is instantiated, it will call your IDispatch::Invoke with this ID.

I have a C++ application that creates a collection of COM objects.
I would like to give the Python interpreter access to these interfaces that were
created in C++ land.
Stated another way, how can I have Python consume a IDispatch pointer from C++
and wrap it with one of those nice Python classes automatically?
Thanks in advance.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
