Christian Weyer (Who? You mean THE Christian Weyer? Yes, THAT Christian Weyer) has made WSDL and VS.NET get along better with his Contract First VS.NET Add-In.

I talked about this in my TechEd: Learning to Love WSDL presentation (which is apparently still up at http://microsoft.sitestream.com/DEV/DEV389_files/default.htm) and many folks smarter than I have said the same thing. 

One of the things that's slick about Christian's imp is that he used his DynWSLib library and handles external schema imports better than the usually obtuse WSDL.EXE.

My quest for the ultimate TabletPC

November 7, '03 Comments [0] Posted in Musings

Matthieu Guyonnet-Duluc wrote me to tell me that a french Geek Site (apparently Geek is Geek everywhere) has a story on a mysterious Toshiba TabletPC M200 [Spéculations et vérités sur le M200 de Toshiba].  Use the Fish if you want to translate it to English, or ask Rory what it says.

Here's the juicy parts of a my lousy translation.  Note this strange news that doesn't jive with my previous scoop about Video RAM.  If this is true, it sucks, and I wonder if it's a heat thing?  I wonder if the Avalon team reads this and has a comment?

Can anyone confirm the release date on this baby?

...you know that Toshiba will leave its new generation TabletPC...used by Bill Gates to show OneNote 2003...

...a little more about the specifications of this Portegé M200...

- have a range of significant power in this model...
- the resolution would seem to be SXGA+ compared with the traditional XGA . In fact the two resolutions are announced in rumour on the Web also it is difficult to have an idea
- the 80 Gb will be with 5400 RPM, while the 60 Gb will be with 7200 RPM
- the video is a nVIDIA last generation with only 32 Mb of Video RAM  -the model with 128 Mb was a non-marketed prototype (Scott: bad news for Longhorn?)
- hardware button to automatically to launch OneNote
- the battery of almost 4 hours
- the bluetooth seems to be integrated
- a Secure Digital Slot

HDD - 40, 60, 80GB (5400rpm) 60GB (7200rpm) (Scott: Definitely the 60GB)

Today's Minor Complaint...

November 6, '03 Comments [5] Posted in XML

Why is this OK:

using (StringReader sr = new StringReader(response))
{
   try
   {
      retVal = xs.Deserialize(sr);
   }
    //yada yada yada

}

Why and this isnt?

using (XmlTextReader xr = new XmlTextReader(new StringReader(response), /*...yada yada...*/)
{
   try
   {
      retVal = xs.Deserialize(sr);
   }
    //yada yada yada

}

Because StringReaders derive from System.IO.TextReader which implements IDisposable and that's what the using keywords cares about.  XmlTextReader derives from the abstract XmlReader, and noone implements IDisposable. I suppose this has something to do with closing streams in the right order, blah blah.  Either way, it was a minor sadness today.

Poop.

Code Generation

Patrick has made CodeSmith sing.  He used it to 'rewrite xsd.exe' to our ends.  Not to mention generate test data, weave in a few AOP-y things, and numerous other goodnesses. I've updated the Ultimate Tools List to reflect CodeSmith's new place in my heart.  Hyperbolic? Maybe, but that's just my style:

Oh, yes, it's much more than just a Strongly Typed Collection Generator. It's a complete code-generation engine with an ASP.NET-like syntax. Very extendable, very powerful, very free. And, only $199 for the source. And all is right with the world. I've used it to generate THOUSANDS of lines of code. There's a learning curve, but the benefits are immense. It's worth the download just for the Strongly Typed Collection code from Chris Nahr.

I'm thinking of drafting Patrick to join me in giving a presentation on said tool at an upcoming PADNUG.  Hm...

Tablet PCs and Math

There's so much potential around the TabletPC and Math.  Folks were buzzing after the keynote where ink was converted into physics animations and equations.  I ever heard people ask “Is it real“ and others insist that clearly it was faked.  Seems to me that while handwriting recognition is a little iffy these days, recognizing numbers and symbols that tend to be a) more varied in shape and therefore easier to recognize and b) used in a more finite domain like Math (as opposed to 100s of languages) would be easier.  The possibilities are endless.  Here's a great app called xThink Calculator (link in French).  Here's something that Loren did for his niece for practice long division.
