Strongly Typed Datasets

by Sander Gerz August 27, 2003 22:09

I'll be writing an article on strongly typed dataset for .NET Magazine. For those who don't know this magazine, that's quite understandable. Microsoft Netherlands publishes this magazine that started out as a one-time intro into .NET development, but turned into a publication that has almost half the readers of MSDN magazine. It doesn't come out every month, in fact, the article is for the 4th one.

Most of you, and the readers of the magazine will have no problem creating a typed dataset. And if not, it's easy to find samplecode on the web. Besides, the xsd.exe tool does most of the work (or VS takes care of it). Not so much to talk about right? So, to make it a bit more interesting my angle will be on the theory behind this type of dataset, when not to use a typed dataset, more advanced features etc. If you have any suggestions, things that are interesting to know, I'm open to anything.

The article will be in Dutch, but I'll try to post my progress here, so there'll be some interesting stuff to read in my weblog as well (at least I hope...).

Crash :-(

by Sander Gerz August 26, 2003 22:18

During an unexpected reboot of my webserver, it did not recover. So my site and this blog went down for the better part of today. I managed to get most of it going, turns out one of the harddisks crashed. I thought this was no problem, until I found out that only my C: drive was mirrored and not the D:-drive. Ok, we have backups... or so you would think. Most backups were somehow corrupted, so D: has only partly been recovered. Most importantly, the date was not lost, since the database is located on a different server (phew). I'll call it a night soon.

Converting sourcecode to html

by Sander Gerz August 26, 2003 10:12

Here's some interesting code. Although it's not documented, it's pretty obvious what it does. It converts sourcecode to html, that is, it appears to do some code coloring that makes it easier to read. This will be very usefull for my site, were I recently added a section on useful codesnippets. I hope to implement this soon.

Passed 70-320!

by Sander Gerz August 25, 2003 15:49

Yep, I passed 70-320 (Xml Webservices and Server Components with Visual C#) today. The exam wasn't too hard, but could have been simpler if I had studied for the right exam! After registering for the exam with Sylvan Prometric, I was under the impression that it was 70-310 (the VB.NET version of the same exam) and I never bothered to check twice.

So you can imagine my surprise when the pre-test questions asked me if Visual C# was my primary development language. Anyway, it's a good thing that the exam mostly covers the .NET framework, and no so much the syntax of C#. Besides, I do most of my home development in C#, so any damage was limited.

Anyway, I'm an MCAD now, but I'm going for MCSD .NET. Only need to pass 70-300 which every MCSD on the older platforms received a free voucher for.

SCO is down?

by Sander Gerz August 24, 2003 13:21

We'll all heard about the fight around Linux that SCO initiated. Maybe it's just me, but it seems SCO is down. I tried www.sco.com, but that results in a DNS error. Did SCO fold?

[edit]
Oh, an update here. It appears that someone attacked the SCO website with a DOS.

The C# design process and checked exceptions

by Sander Gerz August 21, 2003 08:34

You may have seen this article before, but if you haven't, here's two links to an interview with Anders Hejlsberg on the design process of C# and the absence of Checked Exceptions. So far, Java is the only mainstream language that enforces the use of specifications with Checked Exceptions, and some believe there is no real use for it. Anders discusses the trouble with checked exceptions in part two.

Part 1:  The C# Design Process

Part 2:  The Trouble with Checked Exceptions

Another reason why not to use checked exceptions

Crash Different

Scoble points us at a hilarious Apple ad parodyOther bloggers already posted on this video, but this is something I want to show others (and myself) every now and again. So to keep me from forgetting where I put it, here it is. Unfortunalely, I don't know that many Mac-users.

Unable to reach Microsoft.com

by Sander Gerz August 15, 2003 11:07

I'm unable to reach the www.microsoft.com website. Would this have something to do with the much talked about Blaster worm, or with the recent power outage? Or perhaps both? Fortunately msdn.microsoft.com is available. It is curious though that I have not seen any mention of this on news websites. It has nothing to do with our local network, since people from Italy seem to experience the same problem.

VB.NET with generics

by Sander Gerz August 14, 2003 10:14

According to Robert Hurlbut's blog Don Box has said that VB.NET will support generics. Now I thinks this is great. Coming from a typical VB background (started with VB2 in the early nineties), it's great to see a language evolve to become as mature as C++. Alright, this may be a bit too long a stretch, but generics does seem like a great feature. I doubt whether most vb-developers will use it, and that's the basic problem I guess between VB vs. all other languages.

VB is very popular, but mainly because it's relatively easy to learn. Especially VBA, which most people learn by recording a macro and then manipulate the code.  This, of course, has little to do with programming, but a lot of people seem to think they are developers just by manipulating recorded code and maybe copying someone else's code to perform a specific function. So many times, I've been asked to look at some code, be it VB or VBA, that didn't work properly. Just looking at what they were trying to accomplish made my stomach hurt. How do you deal with that? Do you suggest a solution or did try to convince them to give up this exercise and get back to what they were hired to do? I work with financial people mainly.

Back to generics. I'm grateful that this will be available. Switching back and forth between C# and VB.NET (C# at home, VB.NET at work) will be easier.

According to this 1000's of  Xboxes have been stolen. Now, I received an e-mail last week that I've won an Xbox in the TechEd Barcelona prize draw. Surely I hope that my Xbox was not one of these...
