Argument out of range exception: Length cannot be less than zero

[LewE]

I'm just glad it was something simple like a URL change rather than something that affected the scraper.

it was a fairly simple change, but it showed me that I need to put in better exception handling if things like this occur again...

Plus, it brought to my attention a separate bug, which has been fixed

I have a similar problem, I am using the latest version of Weather2, windows xp sp3. Location is Cape Town, no maps selected.
log file extract is-
2010-07-07 13:36:48.765 ERROR [6] FATAL UNHANDLED EXCEPTION:: System.ArgumentOutOfRangeException: Index and length must refer to a location within the string.

I am guessing your regional settings has the year first? i.e. YYYY/MM/DD ?

I have a fix for this, but I haven't made a release yet... As a current workaround, you could change your regional date settings in Windows to something else that doesn't start with a year.

Thanks very much - I changed the short date format as you suggested and Weather2 is working fine.

I uploaded a new version yesterday that fixes this problem (hopefully)
