Testing a website with a root path

This post is really a reminder to myself, so that I can find the information quickly for the next time I reformat my hard drive! To run a website with a root path in Visual Studio 2005 follow these steps: Tools->External tools menu Click Add Title = Webserver Command = C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\WebDev.WebServer.EXE Arguments = /port:8080 /path:$(ProjectDir) Tick "Use output window" Whenever you need the webserver running just open your project and go to Tools->Webserver.

Calling base constructors in C#

I occasionally find it annoying that I cannot specify at which point in a class's constructor I wish to invoke the base constructor. Having C# always invoke it before any of the code in my descendant constructor is executed sometimes causes me problems. Considering .NET is capable of calling the ancestor constructor at any point I wondered why C# wont allow it. I contacted Anders Hejlsberg and he was kind enough to reply, unfortunately he seems to have answered a question I didn't ask :-) Anyway, I have been deleting some old emails today and I came across his response, which he gave me permission to publish: The problem with Delphi's model (allowing constructors to be called on an already constructed object) is that it makes it impossible to have provably immutable objects. Immutability is an important concept because it allows applications to hand objects to an external party without first copying those objects and still have a guarantee that the objects won't

SQL Server amazes me!

Well, SQL Server amazes me, but not because I am impressed! Today I wrote an application that does the following: 01) Find all ZIP files in a specific folder 02) Open each ZIP file in turn 03) Extract an XML file from the ZIP into an array of bytes 04) Insert that data into a table There are 1,978 files in this folder and the XML within each ZIP file is around 2MB in size. I ran this app and was really surprised at how soon my PC started to crawl, it was so slow that it was taking over 10 seconds to switch between MSN and a Skype text-chat window. So I decided to monitor the process..... Importing the zip data into SQL Server took a total of 19 minutes and 15 seconds (this includes unzip time). What concerns me is that SQL Server's RAM usage went up to 830MB at its peak, this is what was crippling my PC. Twenty minutes after my app had finished SqlSevr.exe was still holding over 700MB of RAM, I then restarted my PC. SQL Server was using more RAM than I had avail


Today my baby girl looked at me, said "DaDa" for the first time ever, and then giggled. What a great day! :-)
