Calling Web Page from python addin

LarryWhite — Fri, 25 Oct 2013 11:46:08 GMT

I am using either one the following statements to call a url from a python addin using a thread.
#os.startfile(url)
#webbrowser.open(url,new=0)

Both work with default browsers are either chrome or firefox. The problem it crashes ArcMap when MS Explorer 9 is the default browser. Anyone ran across this? Any suggestions?

The uncommented code works:
this works:

     # this works for explorer
     ie = webbrowser.get('c:\\program files\\internet explorer\\iexplore.exe')
     ie.open(url)

os.startfile and webbrowser.open use COM to do their thing, and they expect the COM runtime to be initialized differently from how ArcGIS does it. You can get around it by calling the function in a different thread.

def open_browser(url):
    import threading
    import webbrowser
    threading.Thread(target=webbrowser.open, args=(url,)).start()

I tried several different solutions and this one worked for me! Thanks all.
