The actual type returned by HttpWebRequest.Create() is a BrowserHttpWebRequest,
but it's internal (not sure why). Anyway, it has a ProgressFailed event you can
hook.
Ok - I'll try that. Thanks Jimmy.
PS. If you REALLY want synchronous downloading, just hack on XMLHttpRequest
def download(url):
request = HtmlPage.Window.CreateInstance("XMLHttpRequest")
request.Invoke("open", "GET", url, false) # false means synchronous
request.Invoke("send", "")
return request.GetProperty("responseText")
:)
Is that cross-browser?
Thanks

Subject: [IronPython] Silverlight and Catching HttpWebRequest Errors
Hello guys,
I have a problem with catching network errors raised by HttpWebRequest
in Silverlight. (Not necessarily an IronPython specific question - but
you guys are so intelligent you are always the first place I turn...)
HttpWebRequest uses an async model for fetching resources. If there is a
problem (triggered usually by a slow response from the server), then it
can happen *after* I have made the request - but before my callback is
invoked. This gives me nowhere to catch the exception, as effectively it
happens 'inside Silverlight'. I wondered if there was a solution... ?
def callback(asyncResult):
...
uri = Uri(some_url)
req = HttpWebRequest.Create(uri)
req.BeginGetResponse(AsyncCallback(callback), object())
The error occurs after BeginGetResponse, but before calback. Any ideas
for catching it?
