ditto on this, i've been using grisoft for probably 3 years now on all of my machines and it's never let me down.

I agree completely with Shawn's advice.  I would strongly recommend using the Enterprise Libraries.  They are well documented and well tested.  Plus they work together as a package.  It is important for applications to have a solid DAL, Logging, Exception Handling, etc.

I would also suggest taking a look at the Smart Client Software Factory (CAB).  Furthermore, you could investigate ClickOnce as a deployment strategy for your WinForms applications.

For a recent project I needed a Flood Fill Algorithm (see Flood Fill in Wikipedia, http://en.wikipedia.org/wiki/Flood_fill

It's certainly odd that performance differs so greatly.

Maybe this is caused (at least partially) by the weird code you're writing, since it doesn't actually do _anything_ right?  This might just be some small compiler corner case.

Furthermore; you're using long's and that too seems unusual.

I played around with your benchmark and discovered that integer overflow checking is at fault - with that off, VB is just as fast.  I wrote a post about it too :-).

Shawn,

  Thanks for organizing a great meeting.  Talking with Charlie and CO. was definately worth the drive from Jax.  The team was really open to feedback and talk many questions from the group.  Every LINQ presentation I see adds something new to a technology I am really looking foward to.

Shawn, I get an error:

'The name 'directory' does not exist in the current context'

oh *** .. nice!

that was supposed to be "oh sh!t ... nice"

Brilliant.  

It's unfortunate that with all the abstractions and libraries out there, these simple things are often forgotten.

Too bad I can't bump this +5 insightful.

to resolve the error you need to add the following to your cs file:

using System.IO;

If you are using this as an ad rotator or the like, then you really need to alter line 4 as follows:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true">

Without EnablePartialRendering="true" your entire page will refresh which is not very user friendly in most circumstances.

hi,

is it possible to use adrotator wothout update panel & scriptmanager?

Hey Shawn -

It was great meeting you at the CLS. Thanks for joining us and for the great participation!

Hi,

I'm trying to integrate a SAPBW connection into my .net website using a SAPBW xml/a adapter. (I've added a web reference to this so I have a .wdsl).

However, I'm stuck with step 3 which shows how to implement the solution for an application rather then a website so it talks about modify the generated webservice proxy??

"Step 3: Modify the WebService Proxy Class, When .NET generates the proxy class it declares the Execute Mehtod with two arguments the ExecuteCommand and a PropertiesType. The PropertiesType is a base class for the DiscoverProperties object, but has no properties. To fix this we actually want to pass a DiscoverProperties object to the Execute Method. While this compiles fine the XML serializer has a problem serializing the request. To fix this add "[XmlElement(typeof(DiscoverProperties))]" before the PropertiesType argument in the Execute Methods Signature. It should look like this "public System.Xml.XmlElement Execute([System.Xml.Serialization.XmlElementAttribute(IsNul lable=true)] ExecuteCommand Command, [XmlElement(typeof(DiscoverProperties))]PropertiesType Properties) {"

"

How do I make this sort of change in a .net website. Do I need to modify the webreference wdsl file?

Any help would be very much appreciated because I can't seem to get over this... (please find my code below).

Shawn,

Great and helpful article. I have one question on the Xml that comes back from SAP(like below). The problem is that the descriptive column names are in the Schema section and the column names in the actual xml are in a "C00000#" format.

How do I would convert this data into a DataSet or DataTable object that has the columns named with the names in the schema?

Shawn:

Excuse me for interrup you in some way. I didn't find a place for put this message for you. I'm new to C# and I need to validate users on my SQL-Server DataBase using Microsoft FingerPrint Reader. I found your solution and I'd like to ask you if you could send me (please) some "steps" I've to follow in order to see how the solution works. I have in my computer SQL-Server and also MS-Visual Studio 2005.

Thank you for any help, It would be greatly appreciate.

We used the web services to Integrate an existing ASP.NET Web Site with SharePoint. So the ASP.NET sends data to SharePoint and possibly kicks off a workflow.

This is a great review of the book! Thanks. I am halfway through it myself right now.  Now all of the authors, except Shaun, are going to be speaking at the next Orlando Code Camp, in a track dedicated to DotNetNuke. http://www.orlandocodecamp.com

Back in 2008 I blogged about Pivot/Cross Tab Queries in SQL Server ( drowningintechnicaldebt.com

Using the example from my last post ( Cross Tab Queries in SQL Server V2 ) I was asked to figure out

That is very cool! You have come such a long way in the community. It's amazing! Congratulations, and we'll see you here in Orlando later this month.

Today was a good day for questions, got one asking how to query the file system from sql server. See
