Recent Microsoft certification exams as a differentiator

paulwhit — Tue, 07 Jul 2009 02:12:17 GMT

I’m coming off of a stint of a few exams in a row to earn my Microsoft Certified Professional Developer (MCPD) credentials for ASP.NET 3.5, which I obtained last week!

In the past year, I have also passed a few Microsoft Certified Technical Specialist (MCTS) exams for SharePoint, and today I failed (eep!) the MB2-634 CRM 4.0 Extending Microsoft Dynamics exam (but plan to re-take it).

Throughout this experience I’ve been considering the impact having these “titles” might have on my employer’s confidence in me and how I’m presented to customers. I refer to the certifications as titles because they’re often displayed in email signatures, including mine:

In my limited experience as an interviewer (I’ve interviewed a dozen or so candidates for various positions within and outside of Microsoft), I have found that the old certifications weren’t terribly useful as a distinguisher. Most of the senior-level candidates had a pile of them (MCSD, MCAD, MCDBA, etc), and they were usually old versions of tests that showed they took a bunch of tests at some point in their career. It was nice to be able to fill in the certification check box, but didn’t always indicate relevant exposure or experience.

Things are slightly different for me now that there are more clearly versioned exams (such as the ASP.NET Developer 3.5 or SQL Server 2008 exams), and I feel that the titles can be helpful to distinguish developers on a few factors:

Active in Microsoft Learning community

With the version-specific exams, I think the most obvious and clear conclusion about someone who takes newer exams is that they make a conscious and committed effort to Microsoft training. Everyone committed to a career that touches Microsoft software (or any other vendor for that matter) may want to pay attention to what the company itself feels is important to learn.

While the learning community is a clear marketing tool for Microsoft to push earlier adoption and drive product sales, it also serves the purpose of producing better Microsoft developers.

In interviews, I usually ask what resources candidates use to keep up on the latest happenings. I like to hear things like blogs, newsgroups, and email distribution lists. Being conscientious of what Microsoft itself pushes out for training shows an additional level of commitment.
Up-to-speed on the latest technologies, to some extent

I feel strongly that Microsoft focuses its exams on showing the power of its technologies, and mentioning common pain points.

Especially with the developer exams, it’s clearly in Microsoft’s best interest to point out gaps and have developers make the best use of its technologies. If ISVs and business application developers can make Microsoft technologies scream, the company will sell more software.

There are limitations to what can be gleaned from a certification list, of course. In my experience it’s helpful to take practice tests to pass exams, but these sometimes seem to promote memorization of question types rather than actual learning. In the end, though, I’ve always learned valuable lessons from the exams and at least have been exposed to much of the power and pain points of the various technologies covered by the tests.
Has specialized or broad knowledge

It seems like the impetus of changes to the title structure for exams in the past few years is to help people indicate what they’ve focused on.

Although I’ve not yet realized the impact of my own certifications, I consider it a bonus for my marketability as a consultant to list the titles on my email signature and on my internal résumé. I think it will help the partners and customers I work with to see my focus areas, and help my management to allocate me appropriately in the future.

Additionally, I want to indicate that I’m focused on being knowledgeable in a variety of areas, so I will continue to take exams in .NET development, SQL Server, SharePoint, CRM, and any other technology that I feel will help me solve customer problems in a more effective manner. I’m hoping my employer will see this commitment and allow me to grow into a more senior role as a consultant and/or architect.

Conclusion

There’s no doubt that Microsoft benefits monetarily when people become certified. Passing active and recent exams helps developers and allows employers to distinguish ones who stay current. It’s not a foolproof method, since passing an exam doesn’t always indicate practical knowledge or experience, but the titles can effectively communicate commitment to learning and staying current.

Disclosure: I work for Microsoft. I get exams, study materials, and practice tests for Microsoft exams for free. I also have access to free exam prep classes (schedule and budget permitting) at internal training events (such as TechReady, an internal training conference) and instructor-led training. However, I still have the same test standards as everyone else and no insight into exam answers.

Walkthrough: Quick Start with SharePoint Web Services

paulwhit — Wed, 08 Apr 2009 11:10:00 GMT

Introduction

Integrating external applications with SharePoint data and functionality is pretty easy, but the documentation is scattered, so I thought it might be helpful to provide a complete solution that covers a few main scenarios.

I’ve used the SharePoint web services to provide a custom search interface and to populate lookup tables. I’ve also seen it used as a workaround in a few scenarios where the SharePoint Object Model was behaving erratically.

This post will focus on how to quickly get started with the web services interface in WSS, and particularly how to access SharePoint data and search results quickly, in a new project. It’s not very polished, but it gets the job done.

Does this apply to me?

First, when communicating with WSS and MOSS, you have to decide which remote access tool best fits your needs.

The SharePoint Object Model (i.e. from the WSS SDK) is great when your application is written in .NET and is deployed to a server running MOSS or WSS,
RPC over HTTP is apparently good for large file uploads,
WebDAV allows for browsing via Windows Explorer and drive mapping, and
The web services interface is best when you need a connection that doesn’t depend on the WSS/MOSS SDK, when you need to connect from outside .NET code (such as via JavaScript).

As Alvin Bruney points out in his book Programming Excel Services (Safari), the web services interface is also “a way to access the resources of the server with reduced risk of instability to the server resources.”

Secondly, figure out if you need to do this from scratch at all.

Check into LINQ to SharePoint, which can use either the SharePoint Object model or the web services interface. It looks like a really slick and robust way to interface with your existing SharePoint data. On the down side, it appears to not have been updated since November 2007 and Bart De Smet, the project’s author (blog), notes that it is an alpha release and not ready for production. I’ve steered clear of it for that reason and due to client restrictions, but you might save yourself a lot of time if you can use it!

Check out this video, from the project’s CodePlex page, for a good quick start:

LINQ to SharePoint quick start video (5:37, 3.18MB, WMV)

If you decide against LINQ to SharePoint, you can still easily add web references and consume the SharePoint web services in your custom code.

Walkthrough: Accessing List data

As it turns out, the web host for Hands on DC (a volunteer organization with which I work) does some hokey things with NTLM authentication that aren’t supported by WCF. Namely, it seems like they’re doing Transport level authentication over plaintext HTTP instead of HTTP over SSL. I can see why this isn’t supported, for security reasons. Despite Dan Rigby’s excellent post about impersonation in WCF, I couldn’t get anything to work.

But alas, with no slight of hand whatsoever, the scenario works in VS2005 and a regular old-school ASMX-based web service proxy (web reference). Here’s a quick (and quite dirty) example, initially based on Ishai Sagi’s (blog) response on MSDN:

Video hint: Click the full screen icon (looks like a TV)

Download source code (39KB, ZIP file)

The query that we send to the list service is written in CAML. When we want to get more complex in our query, such as only pulling back certain columns, check out the U2U CAML Query Builder. It provides an awesome interface into creating your CAML queries.

In the WCF world, Kirk Evans has an awesome walkthrough, Calling SharePoint Lists Web Service using WCF, which includes how to streamline the XML access by using an XPathNavigator, and later using a DataTable that reads from an XmlNodeReader. Better than querying the fields directly for sure!

Walkthrough: Querying WSS Search Results

Search is a little more challenging. As is the case with every other web service, we send the query service XML, and it returns XML. We can take a shortcut and generate the request XML with a tool such as the Search Query Web Service Test Tool for MOSS (or we could also import the schema and generate a C# class from it).

Since I’m a big fan of using XSD.EXE to generate a C# class, I chose to do so with the search result support classes. It was mostly productive, although the Results node is free-form (can take any node type) and the generator doesn’t seem to support that. In the end, we can use the generated classes to get statistics about the data set, and can navigate the Documents using regular XML methods.

Here is a complete walkthrough of adding very basic search results, including a total result count and the first page of results, to our application:

Conclusion

Use SharePoint web services when you have the need to separate concerns and reduce risk inherent with new code deployments to the SharePoint farm, you want remote access to SharePoint from a non-SharePoint server, or you need to access SharePoint from something other than .NET (such as JavaScript).

This post and associated videos walked you through creating a Windows Forms application, from scratch, that pulls data in from SharePoint, including List-based data and search results. The process is similar to any other web service, but there are a few gotchas and pain points that I hope have been cleared up in this resource.

I collected some additional links in the process of putting this post together, and added them on delicious with the tag “sharepoint-webservices”.

Walkthrough: full example of using MvcContrib grid with jQuery datatable

paulwhit — Sun, 29 Mar 2009 06:57:00 GMT

Note: This walkthrough is based on the 1.0 release of ASP.NET MVC, MvcContrib version 1.0.0.916 with a minor code change, jQuery 1.2.6 (included in the MVC release) and jQuery datatables 1.4.

Introduction

For the past few months (and 100+ volunteer hours!) I’ve been creating a web application for Hands on DC that calculates volunteers, gallons of paint, and materials for work projects for their annual Work-a-Thon event. After the encouragement of a few coworkers who did some initial work on the project, I committed to using ASP.NET MVC, technology which has been out over a year but just reached a production 1.0 release at Mix 09 this year.

Getting up and running with MVC wasn’t an easy task. The project was also my first foray into LINQ to SQL, and really .NET 3.5 in general, so it was a little intimidating at first! There’s not much documentation and it’s split across the many release versions of MVC. The main site will get you up doing very basic things (but is seriously lacking content), though Phil Haack’s webcast and Scott Hanselman, et. al.’s free e-Book are helpful.

In the process, I discovered some important companion pieces in MvcContrib and jQuery, including the validation plugin and the datatable plugin. I want to highlight work that I did to combine the MvcContrib data grid with the datatable for sorting, paging and filtering. This was something I struggled with for several hours, so I’m hoping there is some value in posting the full example.

Figure 1. Example of using MvcContrib with jQuery datatable plugin.

Walkthrough

Here is a complete from-scratch example.

Create a new ASP.NET MVC Web Application. Press F5 to make sure it runs.
Drag and drop the “media” folder from the datatable project directory (where you unzipped the project) into the new Solution, like so:

Figure 2. Solution after copying the datatable media folder.

Add a reference to the MvcContrib.dll.
Open the Views/Home/Index.aspx file and add the following under the page directive:

<%@ Import Namespace="MvcContrib.UI.Grid" %>
<%@ Import Namespace="MvcContrib.UI.Grid.ActionSyntax" %>

Open the Views/Shared/Site.Master file and add references to jquery, jquery.dataTables and the demos.css file, like so:

Hide Code [-]

<%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
<title>
<asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title> 
<link href="../../Content/Site.css" rel="stylesheet" type="text/css" /> 
<link href="../../media/css/demos.css" rel="stylesheet" type="text/css" /> 
<script src="../../media/js/jquery.js" type="text/javascript"></script> 
<script src="../../media/js/jquery.dataTables.js" type="text/javascript"></script> 
</head>

Now set up some dummy data in the HomeController.cs file like so (add to the body of the class):

Hide Code [-]

public enum Medal
{
    Gold,
    Silver,
    Bronze
}

public class MedalWinner
{
    public string Location { get; set; }
    public string Year { get; set; }
    public string Sport { get; set; }
    public Medal Medal { get; set; }
    public string Country { get; set; }
    public string Name { get; set; }

    public MedalWinner(string l, string y, string s, Medal m, string c, string n)
    {
        Location = l;
        Year = y;
        Sport = s;
        Medal = m;
        Country = c;
        Name = n;
    }
}

public ActionResult Index()
{
    ViewData["Message"] = "Welcome to ASP.NET MVC!";

    var medalWinners = new List<MedalWinner>();
    medalWinners.Add(
        new MedalWinner("Athens", "2004", "Handball",
            Medal.Gold, "Croatia", "LOSERT, Veni"));
    medalWinners.Add(
        new MedalWinner("Athens", "2004", "Handball",
            Medal.Gold, "Croatia", "BALIC, Ivano"));
    medalWinners.Add(
        new MedalWinner("Athens", "2004", "Handball",
            Medal.Gold, "Croatia", "ZRNIC, Vedran"));
    medalWinners.Add(
        new MedalWinner("Athens", "2004", "Handball",
            Medal.Silver, "Germany", "JANSEN, Torsten"));
    medalWinners.Add(
        new MedalWinner("Athens", "2004", "Handball",
            Medal.Silver, "Germany", "KRETZSCHMAR, Stefan"));
    medalWinners.Add(
        new MedalWinner("Athens", "2004", "Handball",
            Medal.Silver, "Germany", "VON BEHREN, Frank "));

    ViewData["MedalWinners"] = medalWinners;

    return View();
}

Now we have some data to work with. In the view (ViewData[“MedalWinners”]). Test that theory by adding the following code to the “indexContent” content block in Views/Home/Index.aspx:

Hide Code [-]

<ol>
<% foreach (HomeController.MedalWinner winner 
       in (List<HomeController.MedalWinner>)ViewData["MedalWinners"] )
{ %>
    <li><%= winner.Name %>, <%= winner.Country %></li>
<% } %>
</ol>

You should see output like this:

Assuming that worked, we’re ready to do some grid work! Once you get the basic syntax, the MvcContrib grid makes display a cinch. This is the “action syntax” so make sure your imports are right (shown at the top of the walkthrough.

Hide Code [-]

<% Html.Grid((List<HomeController.MedalWinner>)ViewData["MedalWinners"])
       .Columns(column =>
       {
           column.For(c => c.Year);
           column.For(c => c.Location);
           column.For(c => c.Name);
           column.For(c => c.Country);
           column.For(c => c.Medal.ToString());
           column.For(c => c.Sport);
       }).Render();
%>

Run the application; you should see output like so:
That’s pretty easy, but not terribly useful yet. For fun, let’s add a Live search on the name field so we can see who these athletes are. The “Action Syntax” makes it simple to do powerful clean custom code for each cell. Pretty slick! Note that you need to specify the table cell tags or you’ll get messed up output.

Hide Code [-]

<% Html.Grid((List<HomeController.MedalWinner>)ViewData["MedalWinners"])
       .Columns(column =>
       {
           column.For(c => c.Year);
           column.For(c => c.Location);
           column.For(c => c.Name).Named("Athlete Name").Action(a => {%>
               <td><a href=
               "http://search.live.com/results.aspx?q=<%= HttpUtility.UrlEncode(a.Name) %>&form=QBLH">
               <%= HttpUtility.HtmlEncode(a.Name) %></a></td>
           <%
           });
           column.For(c => c.Country);
           column.For(c => c.Medal.ToString());
           column.For(c => c.Sport);
       }).Render();
%>

So now our output name is linked to a Live Search.
Now we’re ready to incorporate the jquery datatable stuff. If you see in the directory that you unzipped the datatable project to, there is an “eaxmple_zero_config.html” file. Let’s steal the code from the top of that.

In order to get this to work, we need to add an id attribute to the grid, as is shown below.

Let’s also style it a little by putting it in a container. Otherwise the search box doesn’t align with the table and looks a little wonky:

Hide Code [-]

<script type="text/javascript" charset="utf-8">
    $(document).ready(function() {
        $('#example').dataTable();
    });
</script>

<style>
#example { width: 100%; }
#container { width: 600px; }
</style>
    
<div id="container">
<% Html.Grid((List<HomeController.MedalWinner>)ViewData["MedalWinners"])
       .Columns(column =>
       {
           column.For(c => c.Year);
           column.For(c => c.Location);
           column.For(c => c.Name).Named("Athlete Name").Action(a => {%>
               <td><a href=
               "http://search.live.com/results.aspx?q=<%= HttpUtility.UrlEncode(a.Name) %>&form=QBLH">
               <%= HttpUtility.HtmlEncode(a.Name) %></a></td>
           <%
           });
           column.For(c => c.Country);
           column.For(c => c.Medal.ToString());
           column.For(c => c.Sport);
       }).Attributes(id => "example").Render();
%>
</div>

Now we can do sorting by clicking the column names, filtering by entering text in the search box, and pagination by selecting the drop-down for “show X entries”.

That’s pretty much it! Before we part, let’s make a quick foray into the syntax of making changes to the datatable initialization code. We can disable columns so they can’t be sorted, create a custom sort order, and change the default length by setting some properties. Let’s disable sorting by the first and sixth columns, sort by name by default, and set the default paging to 25. Just change the javascript block to this:

Hide Code [-]

$(document).ready(function() {
    $('#example').dataTable({
        "iDisplayLength": 25,
        "aaSorting": [[2, "asc"]],
        "aoColumns": [{ "bSortable": false }, null,
            null, null, null, { "bSortable": false}]
    });
});

And voilá!

Get common dates in T-SQL

paulwhit — Wed, 25 Jun 2008 21:10:00 GMT

A few years ago I created an article around Reporting Services and dates. It could have been written more generically, because I reference this quite a bit to get common dates like "the beginning of this week", "midnight last night", etc, in my SQL queries. It's a fairly comprehensive list of relative dates that one might want to get in T-SQL for reporting, scheduling, etc.

It can get pretty complex, such as this function for getting the end of the current week

CREATE FUNCTION get_week_end (@date datetime)
RETURNS datetime AS
BEGIN
   return dateadd(yyyy, datepart(yyyy,
      dateadd(weekday,7-datepart(weekday, @date),@date))-1900, 0)
    + dateadd(ms, -3,
      dateadd(dy, datepart(dy,
     dateadd(weekday,7-datepart(weekday, @date),@date)),0) )
END

If you don't find what you need, you can typically use the dateadd function to tweak one of these. Here is the complete list outlined in the article:

Start of this week
End of this week
Start of last week
End of last week
Start of this month
End of this month
Start of last month
End of last month
Start of the day yesterday
End of the day yesterday
Start of the day today
End of the day today
Start of the day this Monday
End of the day this Monday
Start of the year
Tomorrow at noon
Today at noon

New SharePoint Developer Resource

paulwhit — Sat, 14 Jun 2008 19:00:00 GMT

As part of the Capital Area .NET's new SharePoint SIG, I led a discussion group last week which worked together to create a WSS/MOSS Developer Productivity Wiki Page. Check it out on WSSWiki.com, and please feel free to add to it!

Personal Twitter Client Counter

paulwhit — Wed, 30 Apr 2008 06:10:00 GMT

Get a count and percentage of how many updates you've had with each twitter tool.

Download C# 3.5 WPF Source Code
Note: This source code is mostly a quick hack to get the data I wanted. Also, if you run this on your own data, note that you may need to wait a few minutes for results to come back.

In testing out various twitter clients, I wanted to get a feel for my personal usage (how much I've used each client), so I decided I'd write some code around it. To begin, here are the results:

web, 1770, 41.549%
im, 1214, 28.498%
txt, 713, 16.737%
SnapFoo, 153, 3.592%
twigadge, 146, 3.427%
Twadget, 128, 3.005%
TwitterFox, 61, 1.432%
Snitter, 21, 0.493%
Jott, 17, 0.399%
TwitBin, 16, 0.376%
twitterfeed, 7, 0.164%
Spaz, 6, 0.141%
Twitter Opera widget, 3, 0.070%
twhirl, 3, 0.070%
Twittearth, 2, 0.047%

I snagged an API code sample and fired up my trusty Visual Studio 2005. Thankfully (so I could step out of my box a bit), the code sample was in C# 3.5! So... I popped open my laptop and set out coding (finally, for the first time outside of dragging some controls around) in Visual Studio 2008.

As part of this, I wrote my first LINQ-to-XML query!

This code makes a request to twitter (you have to be authenticated first) and gets an anonymous type list called sc that has the key (the name of the source, as shown above) and the count from that page. After that I work some magic to aggregate them across all pages, though I'm investigating how to do the aggregation by first combining the XElement-s from each page (though that would take up a lot of memory).

url = "http://twitter.com/account/archive.xml?page=" + x.ToString();

WebRequest Request = HttpWebRequest.Create(url);
Request.Credentials = new NetworkCredential(userName, password);
WebResponse Response = Request.GetResponse();
Stream stream = Response.GetResponseStream();
TextReader reader = new StringReader(new StreamReader(stream).ReadToEnd());
XElement statuses = XElement.Load(reader);

// My first LINQ query!
var sourceNames = from source in statuses.Descendants("source")
                  group source by source.Value into sc
                  orderby sc.Count() descending
                  select new { sc.Key, MyCount = sc.Count() };

I also got to play around in WPF just a little. Nothing fancy at all, but it was nice to see the new IDE in action. It feels much more powerful.

I may play around with this some more, add graphing, toy around with it as a Silverlight 2 app. Or it might just sit there and do nothing ;-)

Latest tool: XPath query field extractor for InfoPath

paulwhit — Wed, 16 Apr 2008 10:55:25 GMT

Update: This tool seems to be only relevant with InfoPath 2003. A co-worker pointed out that due the customer pains around a lack of a feature like this, in InfoPath 2007 you can right-click a node in the data source and choose "Copy XPath". Cool! Thanks to Scott Heim for pointing this out.

So, I love making tools. One-off things that process something. Batch files that lessen monotony. Sexy little WinForm apps for displaying data. XSL transformations that regurgitate and pre-process XML.

My latest tool is a small WinForms app that pulls out a list of fields form an InfoPath document so they can be referenced as XPath. This is pretty neat because my client needed a documentation artifact, and this saved quite a bit of tedium. Getting this data also proved difficult because the Namespace URI for the "my" namespace is always changing because it includes a timestamp (see solution below).

Here's a sample of the output. You can use each of these lines as XPath queries against the document:

my:MyFields/my:secMain my:MyFields/my:secMain/my:secPhysicalDescriptionHeader my:MyFields/my:secMain/my:secDualCitizenshipMain my:MyFields/my:secMain/my:secDualCitizenshipMain/my:secDualCitizenshipName my:MyFields/my:secMain/my:secDualCitizenshipMain/my:secDualCitizenship
.
.
.

The tool uses the CAB SDK's extract.exe via a command shell to pull out the template.xml file from the InfoPath XSN file.

The code for using the SDK was pretty straightforward. In this case (since we want the XML template in the InfoPath, the variable ExtractionFileName is defined as:

private const string ExtractionFileName = "template.xml";

And fileName is the location of the XSN file. The code for the extraction is:

// Use the CAB SDK to grab the template file from the InfoPath XSN package
Process proc = new Process();
proc.StartInfo.FileName = ".\\EXTRACT.EXE";
proc.StartInfo.Arguments = string.Format("\"{0}\" {1}", fileName, ExtractionFileName);
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit();

Dealing with the ever-changing "my" namespace

One particular challenge arose. Since the "my" namespace in InfoPath is defined with a timestamp, every time you change the schema the namespace URI changes. So, I had to do a little preprocessing before I could read the fields (since they're all in the "my" namespace). Thankfully the timestamp is of fixed length.

XmlDocument doc = new XmlDocument();
doc.Load(extractionFilePath);

// Use a low-tech way to get the "my:" namespace URI, since it 
// differs by form and when changes are made
string fileContents = File.ReadAllText(extractionFilePath);
int myIndex = fileContents.IndexOf("xmlns:my=") + 10;
string myNamespace = fileContents.Substring(myIndex, 75);

XmlNamespaceManager mgr = new XmlNamespaceManager(doc.NameTable);
mgr.AddNamespace("my", myNamespace);

XmlNode myFieldsNode = doc.SelectSingleNode("//my:myFields", mgr);

After you get the "myFieldsNode" you can recursively iterate through the nodes and output the fields.

Synchronize XSD from an InfoPath document with a SharePoint project for server-side XSD validation

paulwhit — Tue, 15 Apr 2008 10:41:00 GMT

In order to implement server-side XSD validation against an InfoPath form submission, I had to pull the XSD from the InfoPath document archive (XSN file) and use that to update an embedded resource in a SharePoint solution project (including automated checkout/checkin in TFS). I was able to do it using a batch file.

Pretty specialized need, but maybe somebody could make use of it someday ;).

Note: If you want to use this code, you'll have to combine some of the lines that were too long to display.

@echo off 

rem ***********************************************************
rem This batch file is used to extract the XSD files from each

Live Writer: Word+Social media, for bloggers

paulwhit — Tue, 15 Apr 2008 05:28:19 GMT

I just started using Windows Live Writer to update my blogs*. I'm thoroughly impressed with what I see, both from the practical sense and just how much cool seems to surround this thing.

1) My Apartment Building, Washington, DC

Software+Services is Microsoft's answer to the debate about where the future of computing is going in the near future. My take on what this means is a badass WinForms interface with a sexy back-end built around some Web 2.0-ish stuff. That's the technical explanation.

Live Writer epitomizes all of this. It's a lightweight, feature- and graphics-rich editing environment, and it's very closely integrated with a bunch of "Web 2.0" sites, including a pile of blog packages and social media sites.

There are some neat plug-ins "out of the box", including one that took me exactly 12 seconds to show you an image of my apartment building (see image 1).

Plus, there seems to be an active plug-in community developing things to better pretty up source code, integrate with Flickr, Facebook and other sites. Some of em are crap, but the architecture seems like it must be easy enough to be accessible. One cool one is the Amazon Book Lookup plugin (see example below)

Some of the interface features I'm falling in love with include the ability to match the style to the blog's style (so I can switch between the three blogs and see how it'll look in each one), and the ability to pull up old posts from the "Open" menu.

* My blogs:

Use the DescriptionAttribute with an Enum to display status messages.

paulwhit — Tue, 01 Apr 2008 04:29:00 GMT

I've been working on various forms of displaying status messages from enums, and here's the latest preferred iteration of how to do this. Regurgitated and tweaked from WayneHartman.com.

public enum XmlValidationResult
{
    [Description("Success.")]
    Success,
    [Description("Could not load file.")]
    FileLoadError,
    [Description("Could not load schema.")]
    SchemaLoadError,
    [Description("Form XML did not pass schema validation.")]
    SchemaError
}

private string GetEnumDescription(Enum value)
{
    // Get the Description attribute value for the enum value
    FieldInfo fi = value.GetType().GetField(value.ToString());
    DescriptionAttribute[] attributes = 
        (DescriptionAttribute[])fi.GetCustomAttributes(
            typeof(DescriptionAttribute), false);

    if (attributes.Length > 0)
    {
        return attributes[0].Description;
    }
    else
    {
        return value.ToString();
    }
}

It's possible to do something even cooler like cache the values or add a ToDescription() method (in C#3.0), but I just wanted an simple, repeatable way to do this.
