When interfacing to a COM object, is it possible to pump messages in a
thread?
I'm working on an application that automates IE and needs to monitor
IE events (yes I know about Pamie). I'm starting IE as follows:
ie = win32com.client.DispatchWithEvents( object, YamieEvents )
ie.event = w

relatively easy to accomplish. Any thoughts?

I'm working on an application that does some IE automation via the COM
interface. I'm running in a free thread model, sys.coint_flags = 0, and
starting IE with
win32.com.client.DispatchWIthEvents("InternetExplorer.Application",
event_handler_class). Events are arriving as revealed by print state
d the problem is corrected.

My adventures in IE automation continue. I'm now able to start IE, navigate
to a page, and process events as they occur. Unfortunately, when I try to
reference the document after it is loaded and displayed I encounter a number
of problems.
The relevant code is as follows:
self.ie = win32com.

I'm working on an application that automated IE in an apartment threaded
model.
I'm trying to get back the result of ie.Navigate(). According to the MSDN
documentation it should return a HRESULT. It appears to return None. Is
there a way to get the return code from the com interaction?
Thanks.

My misunderstanding.
As far as I know now absent some error all I really expect is S_OK. I'm
adding in the python.com_error checking now and starting careful testing.
If something other than S_OK turns up in the IE interface I'll let you know.
Thanks.

Can pythoncom.PumpWaitingMessages() generate a COM error? In particular if
there is a running instance of IE that is terminated by some external event,
say the user or a script, will pythoncom.PumpWaitingMessages() generate a
COM error since the automation object is gone?
Thanks for any clues.
The GenPY output for IE contains two _dispid_to_func list:
_dispid_to_func_ = {
101 : "OnNavigateComplete",
103 : "OnQuit",
201 : "OnFrameNavigateComplete",
108 : "OnProgressChange",
I'm having trouble using the GetProperty and PutProperty COM interfaces with
IE. Example:
>>> import win32com.client
>>> ie = win32com.client.Dispatch('InternetExplorer.Application')
>>> ie.visible
>>> ie.Navigate('www.google.com')
So there's an IE with a loaded page.

Tim,
You are, of course, completely right as this example which may be useful to
others shows.
>>> import win32com.client
>>> ie=win32com.client.Dispatch('InternetExplorer.Application')
>>> ie.Visible=True
>>> ie.Navigate('www.cnn.com')
>>> ie.PutProperty('aProperty', 'this is the value')
>>> ie.
This group has been very helpful as I've worked on an IE automation class
(yes I know about Pamie). I recently encountered a design issue concerning
how to allow users to 'hook' event routines in the IE automation class.
After a bit of thought and scratching around I decided to look into a user

I'm continuing to work on a class to automate IE in an apartment-threaded
early binding class. The current design is relatively conventional and
looks like this:

however, is NOT the case with OnDocumentComplete. So I'm still a bit
uncertain.
Do you know of any hard test to verify the behavior?
