Hi all,
Need help on this. As you know there is PDA-phone like Pocket PC-phone run on Window Mobile 2003 and above. It has Ms Internet Explorer of scale down version.

So, the question is this kind of device is under mobile device category but having IE browser. So, how to detect this kind of MObile device using MobileCapabilities class?  YOu see, SmartPhone also have Ms IE browser. How to tell them apart?? If I serve Pda-html website to SmartPhone, its screen size will be too small for it.

My objective is this : to detect the PDA device and Mobile Phone .

If it is PocketPC-phone, I will serve PDA-html website or Mobile web base on customer selection.
If it is smartphone or WAP 2.0 -base mobile phone, I will serve  Mobile Web.

please help.

What about checking the capability "browser" = "Pocket IE" from the MobileCapabilities?

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not IsPostBack Then
            Dim Browser_obj As System.Web.Mobile.MobileCapabilities = CType(Request.Browser, System.Web.Mobile.MobileCapabilities)
            If Browser_obj.Browser = "Pocket IE" Then
                Label1.Text = "the is Pocket PC"
            ElseIf Browser_obj.Browser = "IE" Then
                Label1.Text = "Microsoft Internet Explorer"
            ElseIf Browser_obj.Browser = "Phone.com" Then
                Label1.Text = "the is Openwave"
            End If
        End If
    End Sub

Hi TrueLove,

I forgot to ask you this question:

1. Smart phone and PDA-phone both share the same PocketPC internet explorer.

So, base on your code, you can not tell which one is smart phone and which one is PDA-phone!!  My objective is that if I detect a PDA-phone, then I will direct the user to Mobile Page which has bigger Page for bigger screen size.

Can you help on this??

Will the capabilities screenPixelsHeight and screenPixelsWidth help in this case?

 Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not IsPostBack Then
            Dim browser As System.Web.Mobile.MobileCapabilities = CType(Request.Browser, System.Web.Mobile.MobileCapabilities)
            If browser.ScreenCharactersWidth < 20 Then
                Label1.Text = "short text message"
            Else
                Label1.Text = "long text message"
            End If
        End If
    End Sub

My English is very poor ,Maybe I can't express my meaning exactly.

Notice:20 is Characters Width in line
Openwave 7.0 only has 19 Characters
you can test browser.screencharacterswidth value for you Smart phone and  you PDA-phone

better is :

if browser.IsMobileDevice = true then ....

Nope. That just handles desktop browsers. The answer is above.

or if you want to know more than just browser type, try using www.handsetdetection.com - it detects the mobile browser, then returns live results on screen size and device capabilities

How does Request.Browser["IsMobileDevice"] do its work?  The only information that the server has still has to come from the HTTP headers and they are retrieveable from Request.ServerVariables["ALL_RAW"].  How does it catch up with new browsers that come up after the .NET Framework has been released?

I scanned through all the browsers that hit my web server, and it looks like all mobile browsers except one has a non-null x-wap-profile in Request.ServerVariables.  Testing for the presence of this would give a good indication that it is a phone browser.  The one exception is the iPhone.  It does not have this field.  The word "iPhone" is in the user agent field.  But it is still hardcoding.

look at this asp code for mobile detection and redirections

Hello,

for my experience the best strategy to detect mobile devices and mobile browsers is to use the HttpBrowserCapabilities and extend the pre-defined capabilities of the .NET Framework with the actual devices and browsers. I use user agent strings and header information to determine which phone is requesting the page.
