This article will show you basic user agent / mobile capabilities (mobile model, vendors etc.,) profiling using simple VBScript.

Introduction

This article will show you basic user agent / mobile capabilities (mobile model, vendors etc.,) profiling using simple VBScript.

Background

I created a WAP application for getting information about mobile hand set models and their vendors and store it in a simple text file. At first, I decided to create an application using Java, but the problem is that people need to download and install the application; finally, I decided to create a simple WML encoding ASP page.

Using the code

We will now discuss about the ways you can store the handset models and their vendors. At first, I would like to show you the basic UAProfile attribute fetching routine where I use Msxml2.dll, and it has no internal dependencies. The sample code is given below:


'Function GetValue(): used for HTTP POST/Get and XML parsing 

Function GetValue(ByVal url, ByVal name)

    Dim http
    Dim document
    Dim namespaces
    Dim node
    Dim xpath

    Set http = Server.CreateObject("Msxml2.XMLHTTP")
    http.Open "GET", url, False
    http.Send
    
    
    If http.Status <> "200" Then
         GetValue = Nothing
         Exit Function
    End If

    Set document = Server.CreateObject("Msxml2.DOMDocument")
    document.async = False
    document.validateOnParse = False
    document.resolveExternals = False
    document.load http.responseBody

    If document.parseError.errorCode <> 0 Then
         GetValue = Nothing
         Exit Function
    End If
         
    document.setProperty "SelectionLanguage","XPath"
    xpath = "//*[local-name() = '" & name & "']"

    Set node = document.selectSingleNode(xpath)

    If Not node Is Nothing Then
         GetValue = node.Text
    Else
         GetValue = Nothing
    End If

    Set document = Nothing
    Set http = Nothing


End Function

    if profile= "" then
         vProf = split(xwapprofile,",")
         profileurl= vProf(0)
    end if
        
            
    //-----------------------------------------------------------
    retval = GetValue(profileurl,"ScreenSize")
    if retval <> "" then
        screenpara = split(retval,"x") //ok 
        GetWidth= screenpara(lbound(screenpara)) //OK
    else
        GetWidth= 144 //<------- the default width
    end if

End Function

         profileurl= vProf(0)

    else
        GetHeight= 176 //<---- the default height 
    end if
    //--------------

End Function

'Function Is_PDA(): Return true if the request from Windows PDA browser.

                Is_PDA = True
                Exit Function
            else
                Is_PDA = False
            end if

  Dim fs,fname
  Dim varVendor,varHandSetModel,varData
  Dim varProf,varWapProfile
  Dim varProfile 
    
  varProfile=replace(Request.ServerVariables("HTTP_PROFILE"),chr(34),"")
  varWapProfile=replace(Request.ServerVariables("HTTP_X_WAP_PROFILE"),chr(34),"")

  profileurl = varProfile

    if varProfile= "" then

    set fs=Server.CreateObject("Scripting.FileSystemObject")
    set fname=fs.OpenTextFile(Server.MapPath("HandSetList.txt"),8,true)
    // 8 = ForAppending

    fname.WriteLine(varData)

    fname.Close
    
    set fname=nothing
    set fs=nothing

End Function

Sample code of ASP page with WML encoding:

// Include the header file UAProfiling.in (VBScript files)





<% ' Call the VBScript function %>

In thr above function GetValue(), I create two objects:

  1. Msxml2.XMLHTTP, used for the HTTP GET.
  2. Msxml2.DOMDocument, used for the XML parsing.

Conclusion

I hope that it might be helpful to you. Enjoy!
