An introduction to Microsoft Mobile Internet Toolkit (MMIT)MMIT or .NET mobile extends the functionality of .NET framework and enables to develop mobile applications for mobile devices like cell phones and PDA’s. Actually with the use of .net framework we can create two types of mobile applications: web based or local. For web
based mobile applications where applications are executed on the server
and can be accessed from the mobile device via Internet we need MMIT.
Local applications are those which run on the mobile devices.
There are
some software requirements while developing these MMIT based mobile applications.
Firstly we need Windows 2000 coupled with its all service packs and IIS
5. Also there is requirement of Internet explorer 5.5 or more advanced
version, MMIT and ASP.NET framework. By using
.NET mobile we can create a single application for a variety of mobile
devices. Actually MMIT translates the code of application according to
the target device like it will produce WML code for the cell phones with
WAP support. As we have web controls in ASP.NET framework, there are mobile
controls in .NET mobile specification. Along with mobile controls, there
are three other things in .NET Mobile specification which should be discussed.
First is mobile page which contains the mobile application. Next are mobile
forms which are the building blocks of page. Third one is mobile panel
which constitutes the mobile form. Mobile controls
can be divided into three groups: User Interface, utility and validation.
First are User Interface controls which are contained in the user’s
screen or user interface. Examples of this type are Form (represents the
container for other controls), Image (represents an image), TextBox (represents
a single line text box), TextView (multi line text box), Link (represents
a hyperlink) and List (represents a list). Second category
of mobile controls is of utility controls which are also displayed on
the user interface but are more complicated. One of the examples in this
category is AdRotator which displays an advertisement. Also there are
Calendar and PhoneCall controls which represent a calendar and phone call
utility respectively. Third group
is of validation controls which are used to validate the information entered
by the user. In this category we have controls like CompareValidator which
compares the input provided by user to a fixed value or any other input.
There is RangeValidator which checks the range of the input. Another example
is RegularExpressionValidator which checks whether the input satisfy the
specified pattern or not. So with the
development of MMIT based mobile applications user can access information
from anywhere and this has made these mobile devices more popular.
