Detecting Pocket Internet Explorer Server-side
VBScript

• 'Check for Windows CE
• if (InStr(Request.ServerVariables("HTTP_USER_AGENT
  "), "Windows CE")) then
• add Windows CE specific code
• else
• add code for other platforms
• end if
• 'Check for Pocket PC
• if (InStr(Request.ServerVariables("HTTP_UA_OS"),
  "POCKET PC")) then
• add Pocket PC specific code
• else
• add code for other platforms
• end if

19
Detecting Pocket Internet Explorer Client-side
JScript

• var strNav navigator.userAgent
• var isCE strNav.indexOf("Windows CE")
• if(isCE gt -1)
• add Windows CE specific code
• else
• add code for other platforms
• var isPPC strNav.indexOf("240x320")
• if(isPPC gt -1)
• add Pocket PC specific code
• else
• add code for other platforms

20
Scenario 2 Dynamic data display

• More complex demo
• Pocket Internet Explorer connected
• XML-based Web application
• Enables dynamic data filtering without
  reconnecting to server
• Takes advantage of
• Frames, JScript
• Microsoft XML Engine

21
XML Capabilities

• Same XML component as Internet Explorer 5.0
• Markup and transfer of data as XML
• How it works
• Data-as-XML delivered from server embedded in
  HTML page - an XML Data Island
• Data read out of page, parsed, and placed into a
  data tree
• JScript accesses the XML OMand manipulates the
  data

22
XML Capabilities

• Render the XML data in the browser
• Use XSL to transform XML into HTML
• Describe appearance of HTML page with XML
• Instead of CSS, markup page with XSL
• Minimize round-trips to the server
• Easy support for multiplebrowser types

23
Example SolutionInventory control/Enterprise
resource management

• Demonstration
• Activating Web applications with XML

24
Using The XMLHTTP ObjectThe request

• ltSCRIPT LANGUAGEJSCRIPTgt
• var xmlhttp new ActiveXObject
  ("Microsoft.XMLHTTP")
• xmlhttp.Open("POST", "XMLlog.asp", false)
• var strXML "ltchangeprice SKU'" ?
  document.forms0.SKU.value "' ? Price'"
  iNewPrice "'/gt"
• // Send request to logging page
• xmlhttp.Send(strXML)
• // Show response (success or failure)
• alert(xmlhttp.responsetext)
• lt/SCRIPTgt

25
Using The XMLHTTP ObjectThe response

• lt_at_ LANGUAGE"VBSCRIPT" gt
• lt Response.ContentType "text/xml"
• set XMLReq Server.CreateObject("Microsoft.XMLDOM
  ")
• XMLReq.load(Request)
• set xmlAction XMLReq.selectSingleNode("//changep
  rice")
• iSKU xmlAction.GetAttribute("SKU")
• iPrice xmlAction.GetAttribute("Price")
• open recordset containing the requested SKU
• if not rsData.eof then
• rsData("Price") iPrice
• rsData.update
• response.write "Price changed successfully to "
  iPrice "."
