mobile ASP.NET issues

Discussion in 'ASP .Net' started by Wiktor Zychla, Dec 23, 2004.

  1. Hi there,

    I've just started to dig into mobile ASP.NET and I'd really wish to
    clarify few things. I have the experience with ASP.NET.

    1) Some tutorials mention something called Microsoft Mobile Internet Toolkit
    to be installed over .NET Framework 1.0. Is this Toolkit required when using
    ..NET Framework 1.1? At this moment my research indicate that MMIT is an
    integral part of .NET 1.1 and DOES NOT to be installed. Can anyone confirm

    2) [related to 1.] What about so called "Updates" to MMIT? [the last update
    is number 4] Should I download and run the update package in the host
    machine? If yes then is this Update a part of .NET 1.1 SP 1?

    3) lists several
    mobile phones that are compatible with mobile ASP.NET. What does it mean to
    "be compatible"? I need a clarification because I've tested my Noki a 3410
    (it is NOT on the list) and it works with my test ASP.NET page! Does it mean
    that the list is incomplete? It is possible that much more mobile phones can
    read mobile ASP.NET pages?

    4) After I'd noticed that the simple test page
    [, source provided at the end of this
    message] works with N3410, I've started to test other mobile phones. To my
    surprize, the test page does not work with Siemen s ME45 (and two other
    Siemen ses). I've started to dig into that issue and found a page where several emulators are available. The test page works
    with most of emulators but, indeed, it does not work with Siemen ses).
    However, the emulators says (you can see it by yourself) that

    "No WML page found. It's probably a HTML file..."

    and further

    "The page at is not a WML page! It's a
    ordinary HTML page.
    We know this because the server responded with the content type text/html
    when we made a request for
    This would been OK if it was a HTML page we where looking for, but it's not.
    What we want is a WML page."

    This is a big concern to me. Does it mean that the mobile ASP.NET does not
    produce WML page to a mobile device? Most tutorials claim that it does! Or
    does it mean that Siemen s has a faulty or incompatible WML processor? Can I
    address this issue somehow and fix the page to be compatible with this
    particular browser or is it impossible?

    5) what is the purpose of this <deviceFilters> section in web.config file?
    why it is important to define filters? Is it to block some mobiles from
    accessing pages or rather to enable some mobiles to access the page?

    big thanks for the clarification of at least some of these issues
