Retirement Benefits Package - a small project that I did in office..

I had done a Retirement Benefits Package for my offiice. Please check this link out to take a look at my project.. though it's a small one.. still, hope u'll like it..http://retbenefitshomepage.zymichost.com/ I used PHP/MySql which was basically set up on a standalone server in my machine. Since it was LAN-connected, all branches of my company over the country could access it. But I was thinking of making a repository for the whole lot of thing in a web. Then I started looking for free php web-hosting and found Zymichost which did the wonder! It provides you with the following details:

Here are some snapshots of my project..

Hope u've liked my small work.. I wish one day I'll develop my own website and host it without any cost in Zymic. It's of great help to provide such a helping hand to all budding developers. Thanks Zymic!! :)

Configure BSNL Broadband in Ubuntu

Got the Ubuntu 10.04 free CD from https://shipit.ubuntu.com/ that day.. I was struggling for configuring BSNL broadband connection in it.. These are the steps those helped..


Step 1:
Go to your Network control panel.
Follow steps : Taskbar >> System >> Administration >> Network.

Step 2:
Then click on the Unlock button and then it will ask for Administrative password, Enter your Password. and click Authenticate so that it will unlock the locked features.

Step 3:
Click on Wired connection and then its properties, it will show you “Connection setting tab” select “Automatic configuration (DHCP)” from the list and click OK.

Step 4: 
Select Point to Point connection, and go to its properties. It will pop up the pppo properties.
Check the “Enable this connection”, and select “PPPoE connection type” and Enter the account data (Username and Password)in specified boxes,

Step 5:
Go to Modem tab from same Window, select the Ethernet interface (Generally the eth0)
Go to option tab select all check boxes. and then OK. and close.

Now everytime you want to connect to net, just click on LAN Icon on taskbar and go to Dial Up connections and click on Connect to pppOe via modem and get connectiviy.

So now just start your Firefox and start browsing the internet from your Ubuntu. 

Note: This guide is for LAN connection only, and not for the USB connections as many modem manufacturer doesn't provide drivers for Linux versions.

New Way of Generating URL-shortener using PHP

The most famous URL shortener which I've come across so far is Tinyurl. But recently I've seen another one called "bit.ly". Here you can shorten your long URLs using bit.ly : click. Here we're going to discuss about writing small script using PHP through which you can shorten the long URLs. Though I've come across many, I'd like to share here the weirdest process by making folder..!! Really! I found it in Youtube Video Tutorials.. Please check it out.. It doesn't require any database creation even!

Calculate free space on drive using DOS

Run the following from SQL Server to check out the free space amount on a drive.

1. @echo off >nullfile.txt

2. set Drive=C:
3. for /F "tokens=7" %%a in ('fsutil volume diskfree %Drive% ^find /i  "# of free" ')
4.       do set free=%%a
5. set free=%free:~0,-6%
6. echo c: %free%


Now, the following will run a bat file to get free space on a drive and write the results to a table.

• IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.tables WHERE table_name = 'FreeSpace') DROP TABLE FreeSpace

• CREATE TABLE FreeSpace ( SpaceInMB varchar(100) NULL )

• INSERT INTO FreeSpace EXEC master..xp_CMDShell 'C:\Scripts\FreeSpace.bat'

Simplest File Upload in PHP

In many websites, we need to upload files like: our CVs in different job sites, our profile pictures in different social sites etc. It's very useful, and sometimes it has certain restrictions too.. like: you can upload a picture having maximum upper bound of 25MB size etc. Using php scripts, file uploading can be done easily through the following few steps.

Create an Upload-File Form using plain HTML

Create The Upload Script using PHP 

(click here to view the code)

By using the global PHP $_FILES array you can upload files from a client computer to the remote server.

The first parameter is the form's input name and the second index can be either "name", "type", "size", "tmp_name" or "error". Like this:

• $_FILES["file"]["name"] - the name of the uploaded file
• $_FILES["file"]["type"] - the type of the uploaded file
• $_FILES["file"]["size"] - the size in bytes of the uploaded file
• $_FILES["file"]["tmp_name"] - the name of the temporary copy of the file stored on the server
• $_FILES["file"]["error"] - the error code resulting from the file upload

This is a very simple way of uploading files. For security reasons, you should add restrictions on what the user is allowed to upload.

Restrictions on Upload 

In this script we add some restrictions to the file upload. The user may only upload .gif or .jpeg files and the file size must be < 20 KB

Saving the Uploaded File 

(click here to view the code)

The temporary copied files disappears when the script ends. To store the uploaded file we need to copy it to a different location.

First PHP-Mysql Data-Connectivity Project

A very small project on php-mysql data connectivity I'm going to upload here.. Beginners may find it useful. I had to learn everything from the scratch just by going through different websites on php. W3schools is really a good way to start. I didn't use full Php 5.2 and Apache server installation. I just installed XAMPP. Later, I found another small sized version of it, called "xampplite". It's lightweight. And it works cool.
