Many more event videos available at Channel 9 (was: PDC10 – view Microsoft PDC 2010 sessions on your PC)

Posted by jpluimers on 2012/08/28

Dang; I thought this had long left the posting queue, but somehow it ended in the drafts (:

Since then, many more event videos made it to Channel 9, including Build 2011, and TechDays 2012.

Anyway, here it is:

Microsoft’s PDC 2010 was held at the end of October 2010 in Redmond, WA, USA.

For the people that could not attend, it is very nice to view the sessions using the PDC10 player (it seems still people didn’t learn and start stripping the century parts from years again!).

Even if you are not using Visual Studio, .NET Azure or other Microsoft Technologies, there are a lot of interesting sessions showing the directions that Microsoft is taking.
Comparing that to what you do today is always a good thing to do: it helps you reflect, an important part of your personal development.

A few things I found interesting (in no particular order):

  • Asynchrony support in C# 5 and VB.NET 11 based on the Task Parallel Library
  • The choice to favour HTML 5 over SilverLight, even though Internet Explorer 9 and Microsoft’s HTML 5 authoring/development tools are far from ready
  • Azure reporting: is reporting the next big thing on clouds?
  • Offline versus online in the cloud world
  • NuPack – does it bring package management to the same level as Ruby or *nix?
  • XNA for XBox, Windows and Windows Phone

Enjoy!

Great session on how to prevent SQL Injection Myths and Fallacies

Posted by jpluimers on 2012/08/15

A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled  “SQL Injection Myths and Fallacies“.

Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.

He also:

Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.

Watching it you’ll get a better understanding of defending against SQL injection.

A few very valuable points he made: Read the rest of this entry »

Visual Studio 2010: some entries in the Error List are not Errors, Warnings or Messages, but are still indicating a problem

Posted by jpluimers on 2011/04/06

The below message in my Error List is not an error: it has a red exclamation mark, which falls outside the category Error (Red bullit with white cross), Warning (Yellow triangle with black exclamation mark) or Message (White bullet with blue lowercase i).

Bit it is still indicatint something was wrong:

1 Failed to copy project output to file C:\tfs.root\MyServiceApplication\ClientBin\MySilverlight.Client.Test.xap. Access to the path ‘C:\tfs.root\MyServiceApplication\ClientBin\MySilverlight.Client.Test.xap’ is denied. 0 0 MyServices

What it indicates is that the .xap file is readonly, and cannot be overwritten.

The reason is that during checkin in TFS, by accident all the .XAP files were added (by default, .XAP files are not on the binary exclusion list), and I found the answer in this thread.

At the end of the build process, the above message disappeared, but the .XAP file was not replaced, so the project output was not up-to-date.

Ergo: the build should have failed.

The solution was simple:

  1. Remove the .XAP files from TFS
  2. Delete the read-only .XAP files from disk
  3. Rebuild

Now Visual Studio 2010 can regenerate the .XAP files and your project output is correct again.

NB: .XAP files can be in two places, be sure to check both:

  1. The bin\debug or bin\release folder of a SilverLight project
  2. The ClientBin folder of an ASP.NET web project
