Hi,
Anybody has implemented a IE button COM server in PHP ? I have found a python implementation for this in pywin32 package. My objective is to add a button in ie which will on click save the url in the address bar. I am attatching the iebutton.py with this mail. Also, this is a link in msdn instructing add toolbar buttons:
http://msdn2.microsoft.com/en-us/library/aa753588.aspx
Any code snippet will be extremely useful.
Thanks in advance.

"""
This sample implements a simple IE Button COM server
with access to the IWebBrowser2 interface.
To demonstrate:
* Execute this script to register the server.
* Open Pythonwin's Tools -> Trace Collector Debugging Tool, so you can
see the output of 'print' statements in this demo.
* Open a new IE instance. The toolbar should have a new "scissors" icon,
with tooltip text "IE Button" - this is our new button - click it.
* Switch back to the Pythonwin window - you should see:
IOleCommandTarget::Exec called.
This is the button being clicked. Extending this to do something more
useful is left as an exercise.
Contribtions to this sample to make it a little "friendlier" welcome!
