The Top Online Form Builders For Your Website

2015-07-23T15:45:00.001+05:30

In this article you can compare the top online form builders for your website. Here, I have also shown some of the key features you expect to see in a good form builder.

Earlier websites used to have a “contact-us” form with input type fields, validations and a submit button on an HTML web page. These were the essentials of a “contact-us/feedback” form, however certain websites did not have a form. Instead, they had a contact number with live customer service representatives to speak to, or an email address served as a means of contact.

A form is an essential component of a website today and consequently creating a form is not a tedious task and possibly even pleasant. It remains the simplest way to acquire all the necessary information and feedback from a user. Now it's even easier to obtain information on the basis of what a user selects, therefore a form designed correctly could help a website owner identify what type of product and service a user wants.

Several online form builders for a website will be discussed in this article. Before we dig into the common options, let's first look at some of the key features we'd expect to see in a good form builder.

multiplication-of-numbers-using-javascript

2013-08-12T19:23:00.002+05:30

This post will show a simple Code in JavaScript to Multiply Numbers in a particular range.

If you're a beginner, then first try to run your first program in JavaScript.

Write the following code in any text file like Notepad, Notepad++.
Now, save this file as "amitJavascript.html"

<html>
     <head><title>www.techterabyte.com javascript sample</title></head>
<script>
<!-- <script> tag is used to insert JavaScript into html document. -->

function multiplyNum(n) {
   var i, mul = 1; // variable declaration

   // loop to multiply numbers
   for (i = 5; i <= n; i++) {
      mul = mul*i;              
   }

   // this will print the multiplication of numbers from number 5
   alert("The multiplication of digits from 5 to "+ n + " is:\n\n\t " + mul);
}

</script>

<body>
<p style="font-weight: bold;">
www.techterabyte.com<br />
...Multiplication of numbers...</p>
<form name="MultiplicationForm">
   Multiplication of the digits from 5 to
   <input name="enterNum" type="text" />
   <input onclick="multiplyNum(MultiplicationForm.enterNum.value)"

   type="button" value="CalculateResult" />
</form>
</body>

</html>

The above can be explained as:

for HTML tags refer my blog post for html i.e HTML Introduction

<script> : this tag is used to insert JavaScript into html document

!-- --> : these are used for comments

Now. open the above page(amitJavascript.html) under any Web Browser:

Output :(this will shown on the browser as web page)

Enter the maximum value and click on CalculateResult to generate multiplication result:

Through this you can multiply numbers in JavaScript by inserting <script> tag in HTML.

Basic File operations in Ruby

2013-04-16T15:45:00.000+05:30

This post will show different file operations under RUBY. Ruby is an open source programming language developed by Yukihiro Matsumoto.

The file operations shown are:

Reading file data each one by one
Read file data and print it on screen
Read file data using custom delimiter with gets
Reading first 10 bytes from file
Read first 4 bytes and print it under separate lines
Reading file into string data
Finding position withing a file
Writing to a file

The following files are used for below executed program:

file1.txt
Hi, my name is amit
Working at Website

file2.txt
This is second file...

file3.txt
Amit, IT, 24
Ajay, HR, 25

file4.txt (the following content will be written to this file)
This is a test

# code (http://www.techterabyte.com)

puts "Start with reading file data each one by one..."
File.open("file1.txt","r").each { |line| puts line }

puts "-----------"
puts "Now, read file data and print it on screen..."
f = File.new("file2.txt","r")
puts f.gets
f.close

puts "-----------"
puts "Read file data using custom delimiter with gets..."
File.open("file3.txt","r")  do |f|
4.times {puts f.gets}
end

puts "-----------"
puts "Read first 10 bytes from file..."
File.open("file3.txt") do |f|
   puts f.read(10)
end

puts "-----------"
puts "Read first 4 bytes and print it under separate lines..."
File.open("file3.txt") do |f|
3.times {puts f.read(4)}
end

puts "-----------"
puts "Reading file3.txt into string data..."
data =  File.read("file3.txt")
puts data

puts "-----------"
puts "Finding position withing a file..."
f2= File.open("file2.txt","r")
print "Current position:"
puts f2.pos
f2.pos = 8
puts f2.gets
print "Now, Current position:"
puts f2.pos

puts "-----------"
puts "Writing to a file..."
File.open("file4.txt", "w") do |f|
f.puts "This is a test"
end
puts "text written correctly"

puts "-----------"

# code (http://www.techterabyte.com)

The output is shown here i.e $ruby program1.rb

Start with reading file data each one by one...
Hi, my name is amit
Working at Website
-----------
Now, read file data and print it on screen...
This is second file...
-----------
Read file data using custom delimiter with gets...
Amit, IT, 24
Ajay, HR, 25
nil
nil
-----------
Read first 10 bytes from file...
Amit, IT, 
-----------
Read first 4 bytes and print it under separate lines...
Amit
, IT
, 24
-----------
Reading file3.txt into string data...
Amit, IT, 24
Ajay, HR, 25
-----------
Finding position withing a file...
Current position:0
second file...
Now, Current position:23
-----------
Writing to a file...
text written correctly
-----------



This way you can learn different file operations within a single program at beginner level.

Windows7 and Windows8

Windows 8 will launch in October2012.
We can expect some better features from Microsoft regarding Windows 8 like fast boot time etc.
So far what I've read there are some exciting differences:

Automatic applications closing
Windows7 left it up to the user to decide whether he wanted to close the running programs or not. This means that if you started using a lot of programs at once, your system’s speed will slow down and it can hang. Windows 8 tries to help you in managing your programs and your system’s performance as it closes your applications and programs which you haven’t used for a certain time-period so as to help you in keeping your system speed intact.
(windows will auto-save it before closing , but I still think that this feature is not good for
users with Multi-Tasking capabilities.)

Dynamic desktop with dynamic tiles
The Desktop mode in Windows 8 is different from Windows 7, there is no Start menu. Wherever you are in Windows 8, either touching the middle right of your screen or hovering over there brings up a menu, which consists Search, Share, Start, Devices and Settings icons.
Microsoft has replaced the normal shortcut icons with dynamic tiles. There size can be changed and also display information.

Boot time is very fast in Windows8
Microsoft repeated the same before launching Windows7 but now Microsoft has finally made an improvement in boot time which is considered best for users.
(for users too, windowsXP/7 boot time still needs to be fast.)

Interface:
Interface is the default home screen for Windows 8, and features a series of colourful tiles, each offering access to a different application.You can customise your device's Metro interface, adding for instance access apps, web pages, images etc.
Metro is bold and striking and it's colour scheme can be changed to suit your taste. You can also log in to an account, and take your settings and apps with you wherever you roam.It is scalable too.

Built-in Antivirus:
Windows 8 has an antivirus present inside the kernel of the operating system

Mount ISO images without a problem
Windows 8 will mount the image too with Windows 7 feature of burning ISO image to a DVD. This allows you to create a virtual drive to mount the ISO image so that you can easily use it just like a normal DVD.
