[python-win32] How to get IWebBrowser2 from a HWND

[salvatore ventura]

Hi,
 to make things easier, I have attached two htm files that display 
 my scenario:
 - main.htm has a link, that once clicked will open a modal popup
   dialog.htm) that has an input text box.

 What I would like to achieve is the IWebBrowser2 object of the 
 dialog.htm page. I know I can access anything on the page itself
 via the IHTMLDocument2 (which I already have) but that's not my
 need.

 For testing, to make things easy, for now, I open the web page 
 and click on the link from *outside* of the python script, then 
 have the script go ahead and figure the windows names etc etc...

 In the real scenario, one python script will drive the dialog 
 opening, but I will use a second thread to deal with the dialog. 
 I am using PAMIE, and the thread idea is freely mutuated from 
 the cModalPopUp class that comes with it (which only deals with 
 alert boxes and similar though).

 I have also attached a zip file with the whole ball (python test
 script, htm files, the winAutoGui.py that you may know already, 
 and the tlb file for the service provider, which I found on the
 web.

 Thanks again for the help, I will be experimenting other ways
 around this in the meanwhile.

 regards,
 .salvo
