Feed Description: Scott Hanselman's ComputerZen.com is a .NET/WebServices/XML Weblog. I offer details of obscurities (internals of ASP.NET, WebServices, XML, etc) and best practices from real world scenarios.
OK, back to programming, as this is not a political blog. Apparently there's
some trouble with the .NET Framework Service Pack 1. I personally have not experienced
this problem, and I have to admin that it's so obviously weird that I am suspicious
that it is in fact a bug. Lots of stuff should/could never have worked if it
is. It's likely an install/permissions related bug. That said, here's
the details from a recent
series of posts on Channel9.
Symptoms
ASP.NET Forms stop posting back when they have validators on them
Errors in Event Viewer like "Failed while copying the ASP.NET client side script files
to directories under D:\Whatever. Error code: 80070005"
Fix/Potential Fix
Copy a PRE-SP1 version of WebUiValidation.js over the one you have in aspnet_client.
Certainly make sure you HAVE an aspnet_client folder either in that directory or mapped
in another VDIR. (This is a common and unrelated problem.)
I'll get the details/diffs on the changes in this file and post them soon.
