Facebook : beyond the great api they give for extra stuff they are the only ones still allowing title, description and image via href so the code is like this function OpenFacebookShare(title, summary, url, imageUrl) {   var url = 'http://www.facebook.com/sharer.php?s=100&p[title]=' +         encodeURIComponent(title) +     '&p[summary]=' + encodeURIComponent(summary) +     '&p[url]=' + encodeURIComponent(url) +     '&p[images][0]=' + encodeURIComponent(imageUrl);     window.open(url,  'mywindow' , 'menubar=1,resizable=1,width=650,height=450' ); }; as simple as that.

there is a nice trick in XSL that allows us to Create XLS documents. therefor taking any object, serializing it to XML and then using the right XSL we will get our XLS just as we want it, so there is the XSL. notice that if you serialize objects that comes from services the usually come with some [System.Xml.Serialization. XmlTypeAttribute (Namespace= "http://xmlns.bla/bla/yourType" )] and if so the XML nodes will look like this < node  xmlns = " http://xmlns.bla/bla/yourType " > 20:52:00 </ node > and for some reason it wont read the nodes, so the solution is allXmlStr = allXmlStr.Replace( "xmlns=\" http://xmlns.bla/bla/yourType \"" , "" ); < xsl:stylesheet version = " 1.0 "  xmlns = " urn:schemas-microsoft-com:office:spreadsheet "  xmlns:xsl = " http://www.w3.org/1999/XSL/Transform "  xmlns:msxsl = " urn:schemas-microsoft-com:xslt "  xmlns:user = " urn:my-scri
