Visual Studio 'Orcas' Sept CTP download getting confused

Posted Tuesday, October 10, 2006 10:19 AM by Jean-Paul Smit

I've seen other reports of IE getting confused on the download of the VS 'Orcas' September CTP. I had a simular experience with it. It first counts up to 100% within a minute and then counts down to about -1000% (??).

This is the first time I see such behaviour, but since other people also experience it must be something with the download. Probably the size?

Dennis Vroegop had the same experience while downloading Orcas as you can see here: http://www.dotned.nl/blogs/dennis_blog/archive/2006/10/07/266.aspx

Strange that I've only seen this behaviour with Orcas downloads.

Well, actually there is an explaination for this, but i don't know if it's accurate.

If the IE download manager is using a signed Int32 (which has a maximum value of 2147483647) to store the filesize in bytes, the progressbar would not be accurate when the filesize is larger than 2147483647, which is applicable to the download of Orcas (which is 3,6 GB = 3865470566 bytes in size)

As a result, the stored filesize becomes a negative number.

This is one way to explain the negative number, i think.
