SharePoint 2010 Sneak Peak
I guess this will be blogged extensivly the coming hours and days: Microsoft has released official documentation about the next version of SharePoint. Read all about it here: http://sharepoint.microsoft.com/2010/Sneak_Peek/Pages/default.aspx. From that site:

SharePoint Search-as-You-Type with jQuery
Already since a long time I’ve been thinking about a web part that would search-as-you-type using SharePoint’s search engine. The idea behind this concept is that while you’re typing a query in the search box, asynchronously the query is already executed and the results are being displayed. Every time the query is changed, the results will be updated dynamically. This will allow users to see the results without going to the Search Results page, and even more: they don’t have to go back to alter their query. In such a scenario you want to avoid full page postbacks of course, so AJAX-techniques have to be used to accomplish this. A while back my first approach would be to make use of ASP.NET AJAX to build the necessary functionality in a web part for example. But during the last couple of weeks I’ve become a really big fan of using jQuery Javascript Library in SharePoint sites, and it happens to be that the search-as-you-type functionality can be created with the help of jQuery very easily. The beauty of this solution is that everything is happening on the client (in the web browser), so there is absolutely no requirement to deploy something to the server (nowadays this seems to be called ‘Assembly Free’).

My SharePoint Sessions at the Dutch DevDays
Later on this week, on Friday May 29th, I will be presenting two sessions at the Developer Days in The Hague (The Netherlands). I'm pretty excited to be there, not only because it's always lots of fun to speak at this event; but there's lots of cool SharePoint 2007 stuff (IMHO) packed in my presentations:

"The security validation for this page is invalid" when calling the SharePoint Web Services
When working with the out-of-the-box SharePoint web services, it may have happened to you that the Web Service response contained the following exception embedded in the XML:

Determine the URL of SharePoint Web Services using jQuery/Javascript
If you have read some of the previous posts on this blog related to using jQuery in SharePoint 2007 sites, you probably know that it’s perfectly possible to make call the out-of-the-box SharePoint web services by making use of Javascript running in the client’s browser. This opens up a huge stream of possibilities from which I already covered some of them on my blog. A very important piece of information you need if you want to make a call to a web service is of course the URL of the web service. Figuring out this URL seems to be more trivial than it actually is. My first idea was to use the URL of the page in which the call to a web service actually happened; e.g. you’ve got a Site Page accessible in SharePoint using the URL http://mysite/mypage.aspx, so you strip the /mypage.suffix and add /_vti_bin/lists.asmx (if you’d like to call the Lists web service of course). The thing is, this will only work if your mypage.aspx file is setting in the Root Folder of your SharePoint site. For example: when you would put the Site Page in a Document Library instead, the URL of the page would be http://mysite/Shared Documents/mypage.aspx, so you’d have to strip the /Shared Documents/mypage.aspx and replace it with the Web Service suffix. This can get very complicated when you don’t know upfront in what kind of location the page will be stored (a Site Page in the Root Folder or a Document Library, an Application Page in _layouts, ...). It’s possible to write a bunch of code to figure that out, or you can make use of the following technique!
A very easy and quick way to get a reference is to make use of the alternate link SharePoint will but by default in the head section of every rendered page: -
Using jQuery in SharePoint to Display Notifications for Open Tasks
In my previous post I explained how you can make use of the Lists.asmx web service of SharePoint, to load list items by using the jQuery Javascript library. The example discussed in that post is simple and easy to understand, but very, very boring. Let’s try to do something useful with that technique: display fancy, unobtrusive notifications for open tasks, when a user visits a SharePoint site. The screenshot below shows the result, but it’s static. In real life the user would see the yellow boxes popping up, and after a couple of seconds they would disappear again (they don’t block the user interface at all).

Querying SharePoint List Items using jQuery
Due to popular demand I’ve created another sample of how you can make use of the jQuery Javascript library in your SharePoint sites. This example uses SharePoint’s Lists.asmx web service to retrieve all the list items of a specific list. In my previous posts I showed how you could use jQuery in SharePoint Site Pages (regular .aspx pages uploaded to a Document Library), so let’s do something different now; let’s use jQuery in a plain Content Editor Web Part.

Creating List Items with jQuery and the SharePoint Web Services
In my previous post I showed how to make a call to SharePoint’s Lists.asmx web service with the jQuery library to retrieve information about the Lists and Document Libraries that are available on a specific SharePoint Site. In the comments of that post, one of the readers asked if it would be possible to create a new item in a List using the same technique. Of course this is possible, you just need to make use of the UpdateListItems web method (yeah, the name of that method is not very intuitive). Here is a quick example!
