My first time presenting at DevDays was a great experience with me presenting in the community slot. I told the attendees of my session that they were the smart ones because  being at the end of the day, only the dedicated people were left and those dedicated people got two presentations for the price of one timeslot.

The session itself covered how writing JavaScript easier with jQuery and Visual Studio 2010 which you can see below. Now the slides below are not being done using some special PowerPoint to web tool, but are HTML which uses jQuery. Using the same technology as I was presenting on and building it in Visual Studio 2010 really highlighted how powerful and easy this was to do. To navigate the slides click the grey dots at the top or click on the slide and press = to go forward and – to go back.

They are a little wide for the website, so to see them in a new window click here

The demo used jQuery and Visual Studio 2010 to clean up the page, and then connect to StackOverflow to pull down my stats and display them to the audience. The completed demo code (which is not included above, so the demo page won’t work) is as follows (this goes in the HEAD tags in demo .html page):

<script src="jQuery/jquery-1.4.2.js" type="text/javascript"></script>

<script type="text/javascript"> 
$(document).ready(function () {
  $("#DemoButton").click(gapSO);
});

function gapSO(e) {
///<summary>Gets and parses Stack Overflow Points</summary>
  var sourceDiv = $(this);
  var replacementText = "I have ";
  var stackOverflowURL = "http://stackoverflow.com/users/flair/53236.json";
  sourceDiv.html("Loading...");
  $.getJSON(stackOverflowURL, function (data) {
    replacementText += data.reputation + " points and " + data.badgeHtml + " badges on StackOverflow";
    sourceDiv.html(replacementText);
  });
};
</script>
