bit bucket

Explore GIT

There is main problem in uploading the project on GIT.
Many Technical student face problem to

how to upload
how to create repository
how to push
how to pull

Log into Bitbucket under your individual account.
Click Repositories > Create repository or the Create new repository link.
Choose a repository Owner.
This only appears if you are creating under an account with membership in one or more teams.
Enter a Name and Description for your repository.
Tick Private if you want to hide your repository from the general public, so that only selected people can see it.
Select the Repository type.
Click Create repository.

step1 :

Download GIT

Step 2:

create Account on GIT
bitbucket
github

step 3:

use these commands on CMD of Git

$ cd /C/ PATH TO FOLDER

$ git init

$ git add --all

$ git commit -m "adding repo instructions"

commands >.>

mkdir /path/to/your/project

cd /path/to/your/project

git init

git remote add origin ssh://git@bitbucket.org/username/bbreponame.git

Create a project with some code:

$ mkdir my_project
$ cd my_project
$ echo "foobar" > some_file

Then, while inside the project's folder, do an initial commit:

$ git init
$ git add some_file
$ git commit -m "Initial commit"

then for using bitbucket or such you add a remote and push up

$ git remote add some_name user@host:repo
$ git push some_name

you also might then want to configure tracking branches etc. see git remote set-branches and related commands for that.

Implementation of Captcha in Javascript

captcha helps us in understanding and logical implentation of captcha on entirely client side.

Generating Captcha using client side scripting is quite a simple but make sure that the javascript is enabled. Anyways lets move towards the code details.
the source code is quite simple and straight forward.

Source Code

<html>
<head>
<title>Captcha</title>
    
    <script type="text/javascript">

   //Created / Generates the captcha function    
    function DrawCaptcha()
    {
        var a = Math.ceil(Math.random() * 10)+ '';
        var b = Math.ceil(Math.random() * 10)+ '';       
        var c = Math.ceil(Math.random() * 10)+ '';  
        var d = Math.ceil(Math.random() * 10)+ '';  
        var e = Math.ceil(Math.random() * 10)+ '';  
        var f = Math.ceil(Math.random() * 10)+ '';  
        var g = Math.ceil(Math.random() * 10)+ '';  
        var code = a + ' ' + b + ' ' + ' ' + c + ' ' + d + ' ' + e + ' '+ f + ' ' + g;
        document.getElementById("txtCaptcha").value = code
    }

    // Validate the Entered input aganist the generated security code function   
    function ValidCaptcha(){
        var str1 = removeSpaces(document.getElementById('txtCaptcha').value);
        var str2 = removeSpaces(document.getElementById('txtInput').value);
        if (str1 == str2) return true;        
        return false;
        
    }

    // Remove the spaces from the entered and generated code
    function removeSpaces(string)
    {
        return string.split(' ').join('');
    }
    
 
    </script>
    
    
    
</head>
<body onload="DrawCaptcha();">
<table>
<tr>
    <td>
        Welcome To Captcha<br />
    </td>
</tr>
<tr>
    <td>
        <input type="text" id="txtCaptcha" 
            style="background-image:url(1.jpg); text-align:center; border:none;
            font-weight:bold; font-family:Modern" />
        <input type="button" id="btnrefresh" value="Refresh" onclick="DrawCaptcha();" />
    </td>
</tr>
<tr>
    <td>
        <input type="text" id="txtInput"/>    
    </td>
</tr>
<tr>
    <td>
        <input id="Button1" type="button" value="Check" onclick="alert(ValidCaptcha());"/>
    </td>
</tr>
</table>
</body>

create a calandar using PHP

In this tutorial you will learn how to build your own web based calendar using PHP. This calendar is made you can use a plain text editing software such as Notepad.

calandar.php

<?php

$monthNames = Array("January", "February", "March", "April", "May", "June", "July", 

"August", "September", "October", "November", "December");

?>


First we need to check if we have set up our parameters already. If we have not, we set them to the current month and year. (For detailed explanation of date() function please refer to PHP Manual ).

<?php

if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");

if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");

?>


Lets also set the variables that we are going to use in our calandar:

<?php

$cMonth = $_REQUEST["month"];

$cYear = $_REQUEST["year"];



$prev_year = $cYear;

$next_year = $cYear;

$prev_month = $cMonth-1;

$next_month = $cMonth+1;



if ($prev_month == 0 ) {

 $prev_month = 12;

 $prev_year = $cYear - 1;

}

if ($next_month == 13 ) {

 $next_month = 1;

 $next_year = $cYear + 1;

}

?>

<table width="200">

<tr align="center">

<td bgcolor="#999999" style="color:#FFFFFF">

<table width="100%" border="0" cellspacing="0" cellpadding="0">

<tr>

<td width="50%" align="left">  <a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $prev_month . "&year=" . $prev_year; ?>" style="color:#FFFFFF">Previous</a></td>

<td width="50%" align="right"><a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $next_month . "&year=" . $next_year; ?>" style="color:#FFFFFF">Next</a>  </td>

</tr>

</table>

</td>

</tr>

<tr>

<td align="center">

<table width="100%" border="0" cellpadding="2" cellspacing="2">

<tr align="center">

<td colspan="7" bgcolor="#999999" style="color:#FFFFFF"><strong><?php echo $monthNames[$cMonth-1].' '.$cYear; ?></strong></td>

</tr>

<tr>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>S</strong></td>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>M</strong></td>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>T</strong></td>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>W</strong></td>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>T</strong></td>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>F</strong></td>

<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>S</strong></td>

</tr>


// because we don't want our dates to start from 0.

 

<?php 

$timestamp = mktime(0,0,0,$cMonth,1,$cYear);

$maxday = date("t",$timestamp);

$thismonth = getdate ($timestamp);

$startday = $thismonth['wday'];

for ($i=0; $i<($maxday+$startday); $i++) {

 if(($i % 7) == 0 ) echo "<tr>n";

 if($i < $startday) echo "<td></td>n";

 else echo "<td align='center' valign='middle' height='20px'>". ($i - $startday + 1) . "</td>n";

 if(($i % 7) == 6 ) echo "</tr>n";

}

?>


// Now we add just the finishing touches of the html and we have finished the calendar.

</table>

</td>

</tr>
