Microsoft Imagine Cup 2004 - Slovenia 

I just came back from a final event of choosing the best student team in Microsoft Imagine Cup 2004 - Slovenia, where I participated as one of the jury members.

The winning team developed a solution for optimizing warehouse management (JANUS - Intelligent Warehouse System), which was my favourite throughout the competition.

Congratulations to everybody that participated and especially the winners.

 Serious bug in System.Xml.XmlValidatingReader 

There is a problem with schema validation of xs:anyURI data type in System.Xml.XmlValidatingReader.

The schema spec and especially RFC 2396 state that xs:anyURI instance can be empty, but System.Xml.XmlValidatingReader keeps failing on such an instance.

To reproduce the error use the following schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="AnyURI" type="xs:anyURI">
  </xs:element>
</xs:schema>

And this instance document:

<?xml version="1.0" encoding="UTF-8"?>
<AnyURI/>

There is currently no workaround for .NET FX 1.0/1.1. Actually Whidbey is the only patch that fixes this. :)

The problem is even more troublesome when one does not have direct control over instance document syntax/serialization. For example in case of auto generated XML by Microsoft Office InfoPath during digital signature insertion. Attribute /Signature/SignedInfo/Reference/@URI is (according to XML Signature schema) typed as xs:anyURI.

Validation problem therefore manifests itself as inability to validate any digitally signed InfoPath documents.

 Microsoft RD & MVP 

The year 2004 started good for me.

It's official, since both contracts/NDAs have been signed. I'm now a Microsoft Regional Director for Slovenia and a Microsoft MVP in XML.

Thanks to everyone at a local Microsoft sub that nominated me and supported this decision. I feel honoured to be in RD/MVP company.

 IIS horror story 

During preparation for a work presentation for a complex project (designing transport level secure, distributed, endpoint independent web services) I needed to install some benign certificates to an IIS 6 machine. All hell broke lose when I did it and (production) machine failed completely. IIS Admin service would not start, UDDI Services went down, nothing worked.

After numerous hours of trying to fix at least IIS I got an idea of what was wrong.

Apperently the MachineKeys folder, which holds machine account private keys was screwed. No matter how hard I tried reinstalling IIS nothing worked. The solution was in manually deleting MachineKeys folder, encrypting it and setting appropriate permission set.

So, if you are ever in a situation where IIS Admin service would not start causing one of the following errors and you suspect MachineKeys is the reason for it, consider the steps below:

  • The system cannot find the file specified.
  • The handle is invalid.
  • Not enough storage is available to process this command.

Try this:

  • Uninstall IIS
  • Backup files in MachineKeys folder (c:\documents and settings\all users\application data\microsoft\crypto\rsa\machinekeys)
  • Delete MachineKeys folder
  • Create new MachineKeys folder
  • Assign Administrators group, SYSTEM account full permissions
  • ENCRYPT THE DAMN FOLDER (Properties, Encryption)
  • Copy keys if necessary
  • Reinstall IIS

Good luck.
