Though it is not necessary to include current local time in your website, it might be pretty attracting and mesmerizing.

Now lets begin with the tutorial.

First of all we’ll be creating images of numbers “0-9” colon “:” and “AM/PM”. You can create the separate images in any image editing software or you can download the bundle of images directly from here.

Now all the images needed for a digital clock is ready. Next, we’ll be assigning each image for each digits and colons. For instance, refer to the following example:

dgt1 = new Image;

dgt1.src = “dgt1.gif”;

In above sample, we defined that dgt1 will have the new image in the first line. Now, since dgt1 carries an image with it, in second line we again defined the location of source of image that dgt1 will be holding. We’ll be doing this to all of them.

dgt1 = new Image;

dgt1.src = “dgt1.gif”;

dgt2 = new Image;

dgt2.src = “dgt2.gif”;

dgt3 = new Image;

dgt3.src = “dgt3.gif”;

dgt4 = new Image;

dgt4.src = “dgt4.gif”;

dgt5 = new Image;

dgt5.src = “dgt5.gif”;

dgt6 = new Image;

dgt6.src = “dgt6.gif”;

dgt7 = new Image;

dgt7.src = “dgt7.gif”;

dgt8 = new Image;

dgt8.src = “dgt8.gif”;

dgt9 = new Image;

dgt9.src = “dgt9.gif”;

dgt0 = new Image;

dgt0.src = “dgt0.gif”;

dgtam = new Image;

dgtam.src = “dgtam.gif”;

dgtpm = new Image;

dgtpm.src = “dgtpm.gif”;

dgtcolon = new Image;

dgtcolon.src = “dgtcolon.gif”;

dgtblank = new Image;

dgtblank.src = “dgtblank.gif”;

Note: “dgt1” is just a naming and variable, you can replace it anything you want. However numbering is recommended, for example, num1, digit1, symbol1, etc.

Now we’ve assigned images to each of the values in digital clock.

Next, we’ll be creating a function that does the main work of a digital clock.

Let’s name the new function as UpdateClock. And set the needed variables to get the digital values from clock.

function UpdateClock(){

var time= new Date();

hours = time.getHours();

mins = time.getMinutes();

if (!document.images) return;

dgt = mins % 10;

document.images.minsones.src=eval(“dgt”+dgt+”.src”);

dgt = (mins – (mins % 10))/10;

document.images.minstens.src=eval(“dgt”+dgt+”.src”);

if (hours > 12)

document.images.ampm.src=dgtpm.src;

else

document.images.ampm.src=dgtam.src;

if (hours > 12) hours = hours – 12;

dgt = hours % 10;

document.images.hoursones.src=eval(“dgt”+dgt+”.src”);

dgt = (hours – (hours % 10))/10;

document.images.hourstens.src=eval(“dgt”+dgt+”.src”);

document.images.colon.src=dgtcolon.src;

setTimeout(“UpdateClock()”,30000);

}

The script part highlighted in red will determine to replace AM with PM or PM with AM. If the time hour value is greater than 12 then it will load image with PM written in it, else it will return AM image.

This JavaScript function actually shows you the digital clock with 24 hours time format. But we’ve AM/PM image which means that we’ll be showing clock in 12 hours format. Since we’ll need only 12 hours we’ll be substracting each of the value greater than 12 from 12.

Now, if it is 13 hour it will return 13-12 = 1. This is defined in code in orange color. And rest of the codes are used for setting up clock.

And at the end of the code, we’ll be calling the function:

UpdateClock();

Now we’ve created the backend of a digital clock. You’ll have to arrange all the codes above in similar format below:

<SCRIPT>

if (document.images) {

dgt1 = new Image;

dgt1.src = “dgt1.gif”;

dgt2 = new Image;

dgt2.src = “dgt2.gif”;

dgt3 = new Image;

dgt3.src = “dgt3.gif”;

dgt4 = new Image;

dgt4.src = “dgt4.gif”;

dgt5 = new Image;

dgt5.src = “dgt5.gif”;

dgt6 = new Image;

dgt6.src = “dgt6.gif”;

dgt7 = new Image;

dgt7.src = “dgt7.gif”;

dgt8 = new Image;

dgt8.src = “dgt8.gif”;

dgt9 = new Image;

dgt9.src = “dgt9.gif”;

dgt0 = new Image;

dgt0.src = “dgt0.gif”;

dgtam = new Image;

dgtam.src = “dgtam.gif”;

dgtpm = new Image;

dgtpm.src = “dgtpm.gif”;

dgtcolon = new Image;

dgtcolon.src = “dgtcolon.gif”;

dgtblank = new Image;

dgtblank.src = “dgtblank.gif”;

}

function UpdateClock(){

var time= new Date();

hours = time.getHours();

mins = time.getMinutes();

if (!document.images) return;

dgt = mins % 10;

document.images.minsones.src=eval(“dgt”+dgt+”.src”);

dgt = (mins – (mins % 10))/10;

document.images.minstens.src=eval(“dgt”+dgt+”.src”);

if (hours > 12)

document.images.ampm.src=dgtpm.src;

else

document.images.ampm.src=dgtam.src;

if (hours > 12) hours = hours – 12;

dgt = hours % 10;

document.images.hoursones.src=eval(“dgt”+dgt+”.src”);

dgt = (hours – (hours % 10))/10;

document.images.hourstens.src=eval(“dgt”+dgt+”.src”);

document.images.colon.src=dgtcolon.src;

setTimeout(“UpdateClock()”,30000);

}

UpdateClock();

</SCRIPT>

The above codes goes inside the <head> tag of your html template.

Again we’ll need to arrange the placement of the images. Following code will do it.

<IMG SRC=”dgtblank.gif” border=0 name=”hourstens”>

<IMG SRC=”dgtblank.gif” border=0 name=”hoursones”>

<IMG SRC=”dgtblank.gif” border=0 name=”hoursones”>

<IMG SRC=”dgtblank.gif” border=0 name=”minstens”>

<IMG SRC=”dgtblank.gif” border=0 name=”minsones”>

<IMG SRC=”dgtblank.gif” border=0 name=”ampm”>

Orange colored HTML code will place two image sources for hour format in ones and tens numbers.

The brown colored code will place one colon image in it.

The green colored will have ones and tens minute.

The red colored will define AM/PM.

Copy the above code wherever you want inside the <body> of your webpage or blog.

Upload all the images that you’ve created or downloaded to the root directory of your webpage.

If you are having a digital clock in index.html then put the images where index.html is located.

If everything went well, you’ll have a working digital clock.

If you still have a problem, refer to following illustrations on placement of JavaScript and HTML code.

Hope this was helpful.

We can get a hyperlink to open more than two pages via several methods. One of them might be creating a link to a page that will open a pop-up window from it. But this may not sound practical as most of the browser have pop-up blocker enabled in it. Using pop-up cannot be good idea to open multiple pages.

Another best method can be using iframes. Iframes enables us to add two or more different pages to a single page. We can create a single page with two iframes in it and hence can add two different pages in it. Again, this idea becomes flop because; the iframes are not commonly used. Plus, it adds confusion to the visitor because of multiple information in a single page.

If you have been trying to open two pages using hyperlink and searching around the web but unable to find then you are here at right place.

I am going to teach you how you can accomplish this by just a single careful and tricky step.

We all know JavaScript, it can do lots of magic that html cannot do. If you are déjà vu at JavaScripting then you I hope you started getting hint.

Yes, we’ll be using OnClick method and window.open() function.

The default code to open a link from html is:

Onclick=”window.open(‘http://www.google.com’)”

The above code is a JavaScript code that will open Google HomePage. This is a basic code for hyperlinking using javascript.

Now let’s see at the HTML version of hyperlinking:

<a href=”http://www.google.com”>Page link</a>

We all know what that does.

Now when we add onclick parameter to the above HTML hyperlink then we can do any JavaScript magic we want.

See the example below to know what I mean exactly.

<a href=”http://www.example.com” onclick=”window.open(‘http://www.google.com’);”>Page link </a>

In above code, we added onclick parameter to <a> tag. This will enable Page link to carry multiple function. One is default HTML hyperlinking function and another is any javascript function. OnClick is event loader, i.e. when any part of the object between this tag, <a>, is clicked new event will be loaded which will be predefined.

In simple terms, it will load two different links.

Try the above code and play with it.

Not only can two you open unlimited number of different pages just by single click by applying this javascript tweak.

<a href=”#link1″ onclick=”window.open(‘#link2′); window.open(‘#link3′)”>Page link </a>

You can open multipage using the above pattern.

Hope this tutorial was helpful.

Besides changing cookies (in my previous tutorial), you can change other things as well. One of them is changing form values.

Consider the following text field in a money transfer form:

<form action=”submit.php” method=”post”>

<input name=”amount” type=”hidden” value=”1? />

</form>

Assume that above code is the source code extract from a form which sends $1 to your account every time the form is submitted. Lets say that you want to receive $100, how would you do that? The problem in this form is that this form remains invisible since its type is set hidden and neither can you change the value of the invisible field.

By using javascript injection technique you can change the form value easily.

For example to change the value of the above form, you can inject following javascript code:

Javascript: void(document.forms[0].amount.value="100");

The value of the input named amount will change to 100 by applying above injection. The syntax to change form is,

The Green colored text must contain numerical value, the numerical value is the form number where 0 means the first form and 1 means the second form. The orange colored text must contain the name of the input type. For example, in the above form we’ve input name of first form as amount. The blue colored form contains the value to be kept in the input form.

Have a look at following image demo:

You have the form that cannot be modified directly but it is visible.

Now when you look at the source code, you’ll see that it is disabled and you cannot edit the value of this form. This is where you’ll plan and study for javascript injection. Find which form is it, first second or third. If it is first then you must input 0 in the forms[#]. Find out the name of the form and enter the value you want.

Now after everything is planned and fixed, you’ll prepare the javascript injection code and inject it from your browser’s address bar.

Now alert box will show up, this will confirm that the javascript injection went successfully.

Now when you press OK button, you’ll have the form value changed eventually.

In this way you can change the form value easily.

And for some extra fun you can change the title of the website by using following code:

Javascript: alert(document.title = "title name");

This will change the title of the website.

For example,

In Google.com, javascript: alert(document.title); will load the following alert bod.

And when you inject page title javascript injection, you’ll get following result.

Hope you had fun reading this tutorial.

In Javascript injection, javascript codes are injected from address bar of the browser window. In this tutorial we’ll go through the basics of javascript injection, if you are javascript expert then it might be below your knowledge. However freshers might find it interesting and informative.

To command any javascript code to your browser you must inform it that its javascript. It can be done by adding “Javascript:”(without quotes) just before your code.

Below is the sample code to input in your browser.

Javascript: alert("Welcome to HacksPC.com");

The above code is to be typed in browser address bar similar to image below:

After you complete the code, press enter, you’ll see the something similar to below:

In the code typed above, Javascript: is the protocol which you must type before initiating any javascript code snippet. Alert is just the javascript function that gives alert box on the screen. ; is the end of statement command that you have in every programming language, like C, C++, PHP etc.

To have more clear vision about statement end symbol, refer to following example,

javascript: alert("First message"); alert("second message"); alert("Third message");

It gives three separate windows with three different messages.

The alert() function is only used to get information from the website. For example to get form value, cookies etc.

Javascript:alert(document.cookie);

Above code example shows the cookies that are set in your browser by your current website.

This can be very useful if you are trying to hack basic websites. Cookies are set most in page login systems that might be helpful to get illegal access to the website’s administrator page.

For example in above image,  you can see username and password set in cookies section which was revealed with the help of javascript injection.

If the website is not strong enough you can modify the username to administrator’s username and gain full access to the website.

To change the cookie value you can follow the syntax similar to below:

javascript:void(document.cookie="Cookie_name=Cookie_value");

“void” in simple terms applies the function without refreshing the page. Literally, it means that the function won’t return any result.

javascript:void(document.cookie="username=user123"); alert(document.cookie);

The above code will change the cookie value and show the changed value.

You can change any cookie value by applying syntax like above.

To change multiple cookies following pattern will help.

javascript:void(document.cookie="username=user123"); void(document.cookie="password=pass123"); alert(document.cookie);

You can add multiple statements to do multiple tasks at once.

Changing cookie value allows you to confuse the website about your real details like username, log in status, and other dynamic values that are cookied.

Similarly you can change the form value and types. I’ll posting tutorial about form values using Javascript injection shortly. Meanwhile, you can practice with injections in several websites.

Hope this tutorial was informative.

Step 1

Go to python.org , download latest version and install it.

Step 2

Run IDLE (Python GUI)

Step 3

You can run program via python shell or you can run program as python module . py extension.

Step 3.1

Run program via python shell

In Python shell type
Code:
variable = 'Hello World'

and press enter

then type
Code:
print variable

and press enter, output will be Hello World

This is simple example where we store string “Hello World” into variable and then print it out.

Step 3.2

Run as python script . py

Open notepad and type your code

variable = 'Hello World'
print variable

save as HelloWorld.py

Open IDLE and go to File -> Open and open file with .py extension

After this will appear windows where you’ll able to run module, just press F5 or go to Run -> Run Module

Now let’s begin. In order to open a text file in php, we need to call the function fopen(). This will open the file, if it exists, and return a file pointer. Instead of using the file name, you pass a file pointer to functions. Here is the beginning of our code:

<?php
function count_hit()
{
$file_pointer= fopen("hit.txt", "r+");

In the above script, we declared a function by using the keyword function followed by the name of our function. Next, we used fopen() passing the name of a file in the same directory as the script where the page visits data will be stored as the first parameter; we then passed the second parameter r+, this tells the server that we want to open the hit.txt file for reading and writing. For more details about text file handling parameters, please review my previous tutorial about PHP and txt file interaction.
We must create a blank text file named as hit.txt in the directory where the current script is situated.
fopen() can take one more parameter: 1. If you pass the third parameter as 1, the file you passed the name of in the first parameter will be searched for in the include path. We store the result of fopen() in a variable named $file_pointer. If the file does not exist, fopen() will return false. Therefore we’ll need hit.txt initially.

if ($file_pointer == false)
{
return "Error:File not found or could not be opened!";
exit;
}


Now since file is opened, we’ll need to read the file, to do so, we’ll use function fread().

$hit= fread($file_pointer, filesize("hit.txt"));

The syntax for fread is (file open, filesize). To get the file open we’ll be using $file_pointer string and to get the size of the file we use the filesize(“filename.txt”) function. Now the contents of the file are stored in a variable with the name $hit. We will use the trim() function to strip any whitespace from the beginning and ending of the string.

$hit= trim($hit);

Trim will remove all the blank white spaces if exists, this will be helpful to maintain the file size and unexpected results. Now we have read the contents of the file into a variable and trimed up the variable, we will increase it’s value by 1 per hit, and write it back into the file. Before we write to the file, we need to go back to the begining of the file so we can write over the current count. We do this by using fseek().

$his++;
fseek($file_pointer, 0);
$result= fwrite($file_pointer, $hit);
if ($result == false)
{
return "Error: could unable to write file!";
exit;
}
else {
return $hit;
}

We use the increment operator (++) to add 1 to the hit count, then we use fwrite() function to write to the file. We then pass the file pointer and the hit count to fwrite(). If it returns false, the it will show error message. Lastly, we return the value of $hit, which holds the hit count.
Now we’ll need to close the file after reading and writing it. To do that we use fclose() and pass it the file pointer, and also we’ll add some error checking.

$close= fclose($file_pointer);
if ($close == false)
{
return "Error: could not close the file!";
exit;
}

And that’s all, we’re done! Here is the complete script for a hit counter:

<?php

function count_hit()

{

$file_pointer= fopen("hits.txt", "r+");

if ($file_pointer == false)

{

return "Error: could not open the file! It may not exist!";

exit;

}

$hits= fread($file_pointer, filesize("hits.txt"));

$hits= trim($hits);

$hits++;

fseek($file_pointer, 0);

$result= fwrite($file_pointer, $hits);

if ($result == false)

{

return "Error: could not write to the file!";

exit;

}

else {

return $hits;

}

$close= fclose($file_pointer);

if ($close == false)

{

echo "Error: could not close the file!";

exit;

}

}

?>

Now to display the hit on a webpage by adding following code snippet:

<?php echo count_hit( ); ?>

Windows unknowingly supplies the following virtual folders:

Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}

Fonts.{BD84B380-8CA2-1069-AB1D-08000948F534}

Whenever you rename your folder with any of the above name and supply hidden and system folder attributes to it, it becomes completely invisible and inaccessible also in index-able by windows search.

For example rename NEW FOLDER to “’Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” (without quotes).

Now open Command prompt and open the currently renamed New Folder. Set the attributes to +h +s +i

H=Hidden

S=System File

I=Un-indexed

To set attributes input the following syntax (see the image).

There you go, your folder is invisible now and inaccessible.

The above tutorial was just for demonstration. Now I am going to show you how you can arrange it in batch file so that you show and hide the folder just by double clicking a secret icon.

Follow and learn this step by step tutorial.

NOTE:  Just copying and pasting codes won’t make you a good batch scripter, you’ll have to learn and modify the techniques used in them.

First of all let’s plan for the script. What the script must do is check if folder named “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” exists or not. If it exists then we’ll have to direct our program such a way that it will prompt to show or hide the folder. Otherwise if the folder doesn’t exists let the program create new folder with any name (say “Secured”)

The above idea can be formulated in this way:

if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK

if NOT EXIST secured goto MDLOCKER

If there is no matching folder then as soon as the program is executed secured folder will be created. Where MDLOCKER is the separate case (block of code) to create new folder named secured. This time the folder named secured will be visible to everyone. The program will instantly close as creating new folder won’t take much time.

Now you can copy your secret files and documents in the folder named Secured.

After copying we’ll have to hide it and make it invisible. To do so, we’ll rename secured folder to Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D} and supply the attributes to it. This is the main aim of this script.

ren secured "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"

attrib +h +s +r +i "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"

The above code is nothing but our friendly DOS command. When you execute it, you know what it will do.

Now we’ll have to code something to make it visible again. We can do this by reversing the above script. To remove attributes from the folder “-“ is used instead of “+”. And the Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D} folder will be renamed to secured again.

attrib -i  -r -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"

ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" secured</code
