function sendRequest(xmlURL, xslURL, xmlHandler, xslHandler) { xmlhttp = setupXMLHR(); if (xmlhttp){ xmlhttp.onreadystatechange=xmlHandler; xmlhttp.open("GET", xmlURL, true); xmlhttp.send(null); } xslhttp = setupXMLHR(); if (xslhttp){ xslhttp.onreadystatechange=xslHandler; xslhttp.open("GET", xslURL, true); xslhttp.send(null); } } You ll notice that the sendRequest() function uses the setupXMLHR() function to generate the XMLHttpRequest objects. This function looks very similar to the code you ve seen earlier in this chapter, except that it returns an XMLHttpRequest object: function setupXMLHR() { var request = null; if (window.XMLHttpRequest){ request=new XMLHttpRequest(); } else if (window.ActiveXObject){ try { request = new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); } catch(e) { request = false; } } } return request; } The functions xmlReady() and xslReady() deal with the loaded XML and XSLT document. Both functions are very similar: function xmlReady() { if (xmlhttp.readyState==4){ if (xmlhttp.status==200) { xmlContacts = xmlhttp.responseXML; doTransform("contactDetails", xmlContacts, xslContacts); } } } vb.net code 39 reader VB .

The data model in Figure 6-1 shows the two relationships between members and teams: members can belong to teams, and members can manage teams When we implement these relationships with foreign keys, the constraints that are placed on the data are quite simple A member can be in only a team that exists in the Team table, and a team can be managed only by someone in the Member table Other constraints are likely to apply in various situations For example, we might have the additional constraints that a team can have no more than four members and/or the manager must be a member of the team (or not) Referential integrity alone cannot address these rules Relational database products will usually provide some way to enforce such constraints Large systems such as SQL Server and Oracle provide triggers. birt pdf 417, word pdf 417, word font code 128, barcode font word 2007 free, birt upc-a, word 2010 ean 128 vb.net code 39 reader read code 39 barcode with vb . net - Stack Overflow

NET , ASP.NET applications. function xslReady() { if (xslhttp.readyState==4){ if (xslhttp.status==200) { xslContacts = xslhttp.responseXML; doTransform("contactDetails", xmlContacts, xslContacts); } } } They both check for a readyState value of 4 and a status of 200. When these conditions are met, both functions call the doTransform() function. The code calls the doTransform() function twice once from the loading of the XML document and once by the XSLT document. The second call is made from the document that loads last. By that time, both documents are loaded and available for scripting. The doTransform() function follows: function doTransform(docElement, xmlDoc, xslDoc) { if (xmlDoc == null || xslDoc == null) return; if (window.ActiveXObject){ document.getElementById(docElement).innerHTML= xmlDoc.transformNode(xslDoc); } else{ var xsltProcessor = new XSLTProcessor(); xsltProcessor.importStylesheet(xslDoc); var fragment =xsltProcessor.transformToFragment(xmlDoc,document); document.getElementById(docElement).innerHTML = ""; document.getElementById(docElement).appendChild(fragment); } } As mentioned, the function starts by testing that both documents are loaded. If not, the function returns. You can see straight away that there are two different stylesheet approaches for IE and Mozilla. For IE, you can use the transformNode() method, passing the XSLT stylesheet as a parameter. In Mozilla, the code needs to create an instance of the xsltProcessor object to transform XML documents with XSLT. I can use importStylesheet() to import the XSLT document. Then, the transformToFragment() method transforms the XML document into a results tree. I can add the results tree to the document using the appendChild() method. Notice that I had to clear the element first by setting the innerHTML property to a zero-length string. If you don t do this, you ll see the old content as well as the new contact. The stylesheet in this example is similar to the one used in the previous chapter: < xml version="1.0" encoding="UTF-8" > <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <div> <table> vb.net code 39 reader Visual Studio .
