SPARQL Query Tool

SPARQL is an RDF query language, it able you to retrieve results set based on your conditions from an RDF file (such as Tuertle file(s)) or from a SPARQL endpoint (such dbpedia which stores data from Wikipedia web site).
You can imagine what can you retrieve from a rich data web site such as Wikipedia, for example the following SPARQL query will retrieve all triples from Wikipedia web site where "Jordan" is the subject for all these triples:

select ?xlabel ?ylabel
:Jordan ?x ?y.
?x rdfs:label ?xlabel.
?y rdfs:label ?ylabel.
FILTER(lang(?xlabel) = "en")
FILTER(lang(?ylabel) = "en")

you can try this example or other examples on the dbpedia endpoint web query explorer at the following link:

There are several SPARQL query tool to execute SPARQL queries and retrieve the results set such as Twinkle and Jena. Each of these tools has a lot of advantages and some disadvantages, we have developed a new SPARQL query tool that combines the advantages for these tools and avoid the disadvantages.

you can find more about our SPARQL query tool here:

HtmlEditorExtender (ASP 4.5)

This Tutorial  about using HtmlEditorExtender in your aspx pages.
Frst of all  HtmlEditorExtender  can be added as extender for a regular textbox control for example :

<asp:TextBox ID="txtMessageBody" runat="server" TextMode="MultiLine" Rows="10" Width="100%"></asp:TextBox>
<ajaxToolkit:HtmlEditorExtender ID="txtMessageBody_HtmlEditorExtender" runat="server" Enabled="True" TargetControlID="txtMessageBody">

but if you try to run your web site the following error will be appeared  : 
"Sanitizer provider is not configured in the web.config file. If you are using the HtmlEditorExtender with a public website then please configure a Sanitizer provider. Otherwise, set the EnableSanitization property to false."

So you have two choices to solve it  : 
First choice :
If your page is not public you can set the EnableSanitization property to false in your HtmlEditorExtender

Second Choice :
  1. Add "HtmlAgilityPack.dll" and  "SanitizerProviders.dll" in your "Bin" Folder
  2. Add The following in Your Web.Config file :
Under Configuration tag  add


<sectionGroup name="system.web">

<section name="sanitizer" requirePermission="false"

type="AjaxControlToolkit.Sanitizer.ProviderSanitizerSection, AjaxControlToolkit" />




<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">


<assemblyIdentity name="HtmlAgilityPack" publicKeyToken="bd319b19eaf3b43a" culture="neutral" />

<bindingRedirect oldVersion="" newVersion="" />




Under System.Web  tag add 
<sanitizer defaultProvider="HtmlAgilityPackSanitizerProvider">


<add name="HtmlAgilityPackSanitizerProvider" type="AjaxControlToolkit.Sanitizer.HtmlAgilityPackSanitizerProvider"></add>
