XPCOM: Cross Platform Component Object Modeling Tool

XPCOM or Cross Platform Component Object Model is a multi-faceted computing Web & Software Development model intended by Mozilla. XPCOM is analogous to Component Object Model (COM) which is an interface standard set for software componentry files; it was introduced by Microsoft in the year 1993. XPCOM also satisfies COBRA (Common Object Requesting Broker Architecture) technology standards that enable software components written in multiple computer languages running on multiple computers to work together.

It is a concept that is implemented as well as inter-operated on multiple Computer Interfaces. It has multiple language bindings along with IDL (Interface Defined Languages) which allows programmers to plug their custom functionality into a framework which can be connected further with other components too.

Web application development is the process or can be called as practice of developing application that is accessed via web browser over a network such as the Internet or an intranet. XPCOM is a similar kind of Web Application Development tools that encompasses both Business-to-Customer (B2C) and both Business-to-Business (B2B), solutions. It is one of the leading technologies for web development in India. XPCOM development covers multiple technologies moreover with different verticals helping us in delivering quality offshore services for web site development.

XPCOM is the only thing that makes Mozilla loaded software application environment into an actual framework where people can work upon. It is a web and software development application that provides following subsequent features to all cross-platform software developers:

 

    • It allows Administration of different Components

 

    • It allows easy abstraction of files from various sources

 

    • It makes Object message passing an easy task

 

    • Gives adequate options to Manage Memory Allocation

 

  • On the whole gives affordable web development

The flexibility provided by XPCOM to reuse various Cross Platform Components from Gecko library for development of new components which run on diverse platforms facilitates rapid Web Application Development. This flexible option on the whole makes web and software development a simplified task. Application based on XPCOM is productive as well as easy to maintain and work over.

C and C++ Easy way up

C: Middle -Level Language
If you are a C,C++ programmer than you are in the right place.
We are here to program in C and C++ but we will more vocus on C++. This is not because C isnt an important language, C is a language from which C++ is built. C++ is a language in which you can make write programs for Windows 95/98/NT/2000 and DOS envirioment a program which has been forgotten by many. DOS come with Wiindows.
We will start on what C++ is built from C.
Quick facts of C:
>>C was first invented by Dennis Ritchieusing a UNIX OS.
>>C started from an older language called BCPL DEVELOPED BY Martin Richards.
>>Ken Thompsons invented a language called B, from which C was developed in the 1970s
>>With C you can manipulate bits,bytes and addresses
>>C is a portable language
>>C is a structures language. Structured in a distiguished manner in that it is Compermentalized- The ability of a language to section off and hide information and instruction that perform a specific task.
>>C was first used for system programming -class of programs that form a portion of an operating system or it utilities.
Examples: OS, Interpreters, Editors, Compilers,File Utilities,Performance enhancers, Real-time executives

Position of C’s in the language of Programming
Higest Level->Ada, Modula-2, Pascal, COBOL, FORTRAN, BASIC,
Middle Level ->C#, Java,C++,C, FORTH,Macro-assembly language
Lowest level->Assembly
The Subsets of C (Note this is the foundation of C++)
Data Types: Set of values that a variable can store along with any operations that be carried out with that variable
Char -Holds ACSII characters, or any 8-bit quantity.
Integer-Holds integer quantites
Float -Holds real numbers
Double -Holds real numbers
Type Modifiers: signed
unsigned
long
short
Defaukt interger assumes a signed number.Diffrence between signed and unsigned is the high-oder bit.
Access Modifiers: Constant-not changed during execution
and Volatile- indicates that the variable in a diffrent manner not known to the program.
Declaration of Variables:
type variable_list; where type is either char, int etc
variable_list any identifier separated by commas
Hope you’re getting the idea, you must get the idea. Lets continue you getting there

One of the most popular programming language.

Java is a complex and object oriented computer programming language, which was by developed by James Gosling, Sun Micro System and released in the market in 1995. Java is the most versatile programming language which is made after including the concepts of C, C++ and some other languages used in computer programming. This language can be used in application development for any platform including the computers as well as the mobile phones. Android relies completely on Java platform for its application development tasks.

Here are some basic reasons for popularity of Java application development platform:

• Platform Independency and Portability: Java is mostly preferred for its platform independent and portable behavior. It provides users the facility to “Write once, run anywhere” as the programs are need to be written once and that program can be used at any platform or operating system.

• Security: Java is the most secured language. It was made under the consideration of being secure in every field. Java allows the non-trustable codes to get downloaded and run without harming the entire system. It resists the viruses and disables them so that they cannot affect the system files. It does not allow the virus codes to read or write the program files so the program remains unaffected from the misuse of the codes.

• Usability (Allocation and Accessibility): Java uses stack allocation system which provides better allocation to the files. The stack allocation means LIFO (Last In First Out). This allows the last file saved to be open first and the APIs of the Java makes it very easy to use for the developers.

• Reusability of Codes: The codes used in the programming of Java applications can be reused in developing any other application. A feature of Java allows for this reusability to provide an independency to the developers in creating modular programs.

• Quick development: The application development process of Java applications is very quick and very easy to build. The sets of APIs used for the development are very well designed and powerful by the help of which the development process saves time as well as money.

• International: The Java language uses a 16 bit Unicode Characters which presents the phonetic alphabets of the whole world. It is the only type of language having these kinds of features which make it international at its very essence.

It is not the end of the features and the reasons of popularity of Java application development. There so more features like its dynamic and extensible nature, network based apps, open-sourcing which makes it free to use for the development purpose, etc.

All these above reasons for its popularity are given by the expert team of market analysts to serve you the information about the Java application development.

Programming Solutions

You know why it’s difficult to begin to learn a programming language? If you are reading this you ought to have noticed that it’s becoming difficult to merge out as a professional developer of any programming language. I happen to save many students from the sad news that you have to learn a language for at least six years to understand it. My girl friend learnt Chinese language within eleven month as opposed to the twenty four months.
Here is how to get a grip to any language you desire to learn.
Get sites that illustrate simple example rather than those that throw a complex coded application that you hardly can find out the beginning and the ending. By using simple examples, they tend to ease your abortion level and guide you step by step up the ladder. You may come to discover that you will have learnt a lot in a very short period of time.
Simple examples explain what variables do and how they do it. You can even go to an extent and discovery why.
In the process of learning do not receive blows you cant block, I mean try to learn what you can accommodate, it would be better to learn in short intervals of two hours maximum. By choosing a topic for example, introduction to C++, Fundamentals of C++, you can divide your learning to portions you can swallow. This allows the brain to grasp more. Believe me I used to learn five pages and that was it.
As you proceed you will extend your time with the rate you are absorbing the language. Some topics need more time to grasp and running through the topics means that you’d have to come back to the same topic. This will really consume your time.
Learning varies among us. My classmates were wizards, simply because they used to cram. I came to understand later that they had little understanding on what they crammed. Listen, avoid cramming. Instead, understand why and how the program is working. By doing so you not only improve your understanding but up create opportunities and chance of your brain been more flexible to create new programs. Programming is putting down your imagination down and modifying it to become a more real event by programming it. So don’t restrict your mind from thinking.
We live in a mixed community; we have all sorts of people. I particularly choose the masters of all and doers of none. Get these tough masters of the programming language you want to learn. They know each corner of the language but they don’t program, let them pass the knowledge to you and you’ll be surprised by what you can do. This saves you from going far searching for details.
