Car Loan Calculator – Php Basic Programming

First we will have to create a new PHP file: simplecarloancalculator.php. A PHP file is rated by the web server as a normal HTML file except for the code written inside a php tag.
We start off by creating the car loan calculator HTML form submitting data back to this web page.

Car price: Term: Interest rate: The code above will create a form containing three text boxes and a button.

 Car price: ___
 Term: ___
 Interest rate: ___

Can be translated to:
When the calculate button is pressed the data in the text boxes will be sent to the page named: simplecarloancalculator.php (the page we have all ready have loaded in our web browser). Our current page simplecarloancalculator.php will be reloaded and we will have access to the data entered into the form in an array named $ _POST.
To be able to use the data entered into the car price text box we use $ _POST [carPrice], where carPrice is the name used in the form above. Since we in reality are using the PHP code before the form is created we will place the code above the form.

PHP coding

We will start off with two functions and one variable.

Isset () – function to test if variable is set [returns true / false].
Empty () – function to test if the variable is empty [returns true / false].
$ CarPrice – variable to store the car price in.

Looks like isset () and empty () are doing pretty much the same but I will soon explain the slightly but very important difference.
Let us examine a code snippet.

If (isset ($ _ POST ['carPrice']) &&! Empty ($ _ POST ['carPrice']))

$ CarPrice = check_input ($ _ POST ['carPrice']);


$ CarPrice = 0;

Isset ($ _ POST ['carPrice']) -> If something was posted in texbox named carPrice (will return true even if an empty box was posted).
Empty ($ _ POST ['carPrice']) -> If nothing is in $ _POST ['carPrice'] (will return true first time the page is loaded).

Combined together the expressions (please notice the! Before empty function) will be evaluated as:
If something was typed in the text box named carPrice and the box was not empty. Variable $ carPrice
Will be set to that something, otherwise set variable $ carPrice to 0.

The same procedure will need for term and interestRate as well, creating variables $ term and $ interestRate, but that code will not be repeated here.
Time to do the mathematical work.
We will next create a function taking the three input parameters $ totalLoan, $ years and $ interest. The function will then return the cost per month rounded off to whole dollars.

Function calculateMonthlyAmortizingCost ($ totalLoan, $ years, $ interest)

$ Tmp = pow ((1 + ($ interest / 1200)), ($ years * 12));
Return round (($ totalLoan * $ tmp) * ($ interest / 1200) / ($ tmp – 1));

Next step will be using our newly …

Guidelines for Writing Software Copyright

Software copyright is an important issue nowdays, with all the companies that invest serious amounts of money in developing applications that are meant to ease people's work. Therefore, if human and financial efforts are involved, it is only natural that any piece of software should be protected against unlawful use.

The solution for this thorny problem is writing the software copyright. Fail to do this, leave your product unprotected, and you may find sooner or later some other person featuring with all your hard work and taking all the credit (including, most likely, financial benefits).

A Definition

Copyright Practically indicating the right of a certain individual or business entity to make copies of a particular work and use these copies according to wish or necessity. When it comes to software, it refers to the right to copy and use the relative software, or portions of it, according to some very well defined rules, while respecting the software author's intellectual rights on its work.

Software copyright is backed by the EULA (End User License Agreement), in which the user's rights regarding the software are strictly specified, as opposed to the rights of the legal and rightful owner of that particular software. The software copyright laws indicate that it is illegal for any other individual or business entity to run, copy, modify in any way or distribute a program without the express consent of the rightful owner.

Most of the times, this consent comes under the form of licenses, which mainly grant the right to use, with certain limitations, the software in cause. Copyright issues are usually stated within the EULA.

What You Need to Know About Software Copyright

The first and most important thing to know about copyright is that it only applies to script software and not to ideas behind it. Just because you had an idea or said something does not mean you are entitled to copyright. But, when you put your pen on the paper, (fingers on the keyboard, in our case) the result automatically becomes your property.

Technically, the author of the software code is the rightful owner of the copyright. When software is created by a company's employee during the official work hours and in keeping with the job description, the copyright automatically goes to the company.

But when software is created as a result to commissioned, specifically ordered work, or by a company's employee outside the normal work hours or at a special request, additional documents have to be created in which it is right owner of the software, and, therefore, who can raise copyright claims.

If your software will be distributed (ie sold by retailers), then make sure you give the licensing section of the EULA as much attention as possible. This is where the information about software copyright is included. …

Why A Mobile App Is Needed

Due to growing mobile app development, companies, irrespective of size & function are making their move towards the development of their own business app. We are living in an era influenced by technology and the latest technology to connect with the target customers is a Smartphone. These phones have become very powerful after the introduction of mobile applications.

These applications are doing wonders for businesses of all types and are efficient enough to develop a long-lasting relationship with audience. Today, companies are making fantastic profits by the help of mobile applications. Similarly, those companies which have not yet taken step towards mobile app development, are surely losing out on opportunities.

If you are running any business and have not yet thought about application development, make sure you know the following;

Apps make businesses highly visible to target audience

According to recent studies and researches, mobile devices are being used in the world almost 6 times more than desktops/laptops. Today, the biggest medium of online shopping is mobile because they are instantly available.

Old days have gone when companies used to inform their audience about their events and special offers through print media. Today, apps are doing everything and it has become extremely easy to convey business message to the potential customers in terms of latest offers, new arrivals, special deals etc.

Apps recognize business in target markets

Undoubtedly, mobile presence in this age helps businesses to get recognized among target markets. But the application must be well designed and functionally controlled so that it can help users find the instant solution of their respective queries. Whatever app you develop, make sure it has something interesting and unique for the audience.

Applications help develop effective communication

It is very important that you have a strong communication with your target audience and this is what a mobile app does efficiently. If you have a successful application and it communicates well, nothing will stop your customers to purchase from you.

However, mobile app development can be beneficial for your business in another way. Although, the app development is becoming common but still there are companies which have not yet given a thought to it. If your competitors have no app, you can take an advantage and your services can stand out.…

Common Errors in Metatrader 4

Metatrader has a built-in error identification mechanism within its terminal. Like most software, errors detected are expressed in numerical codes. The errors can usually be found under the experts or journal tab of your Metatrader terminal window. If you are using custom software for trading, such as an expert advisor or script, you may also ask your programmer to display the errors on the screen. This articles lists the most common errors experienced by traders while using the trading terminal.

Error 3 "Invalid Trade Parameters"

It means that one or more of the trade parameters of your most recent order was unacceptable to the broker. If the order was sent by a human trader, check the lot size, stoploss, and takeprofit values ​​and see if they meet the requirements of your broker. If it's an expert advisor, you should also check on the comment variable, as giving a null value or double quotation marks ("") to the variable are sometimes rejected by the server.

If the last order sent was for a pending order, check if your broker allows pending order expiration. Some brokers disable this feature, and would only accept a zero value for the variable.

Error 6 "No connection with trade server"

It simply means that the terminal is unable to connect to the server. This could be a server fault, but it's often a local internet connection problem.

If your internet connection is fine, check the internet connection status at the lower right-hand portion of your Metatrader terminal. If the status says either "No connection" or 0/0, then your terminal experiencing a problem in using your internet. Restart Metatrader immediately. This does not happen often, but could be an alarming issue if left unnoticed.

Error 8 "Too Frequent Requests"

This error can also be encountered by human traders, but expert advisers are more likely to experience it. Each broker has a limit on the number of requests it can take for any given account. This error appears when an account has reached that limit. This is often a sign of bad expert advisor programming or bad EA logic. Reconsider the rules on the EA.

Error 65 "Invalid Account"

This error often happens in demo accounts. Most demo accounts have a date of expiration, and when they reached it, such accounts are considered "invalid." No one, not even an expert advisor, can trade using an invalid account. Just create a new demo account.

If it's a real account, then you have a real problem. Contact your broker immediately.

Error 129 "Invalid Price"

For expert advisors, if encountered a lot and consistently, it's a sign of bad programming. For human traders, it's a sign that the market currently being traded is highly volatile. It could have been purely caused by market factors, such as trading news.

Error 130 "Invalid Stops"

Invalid stops means that the stoploss, or takeprofit, or both, are unacceptable to the broker. Brokers often set limits to stops to limit their risk. Make sure that your …

Three Ways to Make Money By Selling Domain Names

Some of the domain name speculators wouldn’t bat an eye when someone mentions the words “Selling Domain names.” This is because domain name speculators consider domain names to be of value and they’re already used to selling domain names online. Do you know that you can still make money online from domain names?

There are at least 3 ways you can use to make money with domain names. Let us discuss each way in details below:

1.) Domain Name Flipping

Domain name flipping involves the practice of buying domain names and thereafter reselling them for a profit. It is like the business of real estate. An investor purchases a home or land and then turns it around. Later on, he sells it to someone else for a higher price. In this case, it’s a domain name that is bought and sold at an amount that is higher than the cost price. How do you flip a domain name?

It is not all that difficult but you should do your research well so as to avoid making losses. Remember your aim is to make a profit. The first thing to do is buy one domain name or more domain names. Be sure to make a wise choice. The domain name needs to be short, easy to remember and possibly contain a keyword phrase. If possible get a dot-com, however, you can settle for a dot-net when the dot-com is not available (already registered).

Now, you have to resell the domain names you have purchased. You can easily do this by using a third party website like Sedo, eBay or Flippa. You can create a listing for the domain names you’re selling alongside their prices. Those interested will be able to contact you with their offers.

Bidding websites can be of advantage or disadvantage to use when selling domain names. They’re advantageous in that you can sell at higher amount than the price you had paid for that domain name hence making big profits. The disadvantage is that you may be obligated to sell to the highest bidder, even if the final amount is very low than what you were expecting.

2.) Using the Domain Name

Another way for earning money with a domain name is to use it. You’ll need to purchase a web hosting service in order to use your domain name. This service allows you to upload content, images, and videos to the internet so that they’re published on your website. This means that you’ll need to build a website.

When building your website, forgo trying to make it too pretty and instead create it to be easier to navigate its pages. Next, you’ll want to find a money-making opportunity so as to monetize your website. Choose a website concept that is profitable in order to monetize your domain name. Such examples include Christmas gifts, wedding gifts, gifts for friends etc. Create content about the topic you have chosen and publish it on your website. Note that the content …
