An analysis report on payroll system with diagrams is the 2nd most visited article. As per visitor’s interest I am writing this article to help you technically design your own payroll system.
I am not aware what computer language you prefer. So attaching source code for sample payroll system in maximum of languages. This is just for your reference and ideas. So you don’t leave any functionality by mistake while designing the whole system. It’ll also help you to complete your payroll system project in less time. And will give you an idea about screen designing.

Please rescan the downloaded files because I afraid from hackers before GOD

Let me know by your comments if you need more screen shots, source code or something else that can help you.

You’ll find many posts over wordpress security plug-ins. But I had excluded all plug-ins which do less work that you can do by changing some settings. Like creating .htaccess file etc.

I also not mentioned plug-ins related to SSL. SSL certificates let you connect to your server with encrypted channel which is very secure. You need to buy SSL certificate. You can use shared or private certificates. But in both cases you need to payment. Since most of the bloggers doesn’t go for buying SSL certificates. So I avoided them.

You can achieve full security by using very less number of plug-ins. Some of them are;

Akismet - It helps you to protect from SPAM. In simple words you can say. If someone comments on a post just for advertisement or uses offensive word then Akismet can stop them.

Block Bad Queries (BBQ) - I hope all of you are aware with SQL injection. SQL injections are nothing but some complex SQL queries written with the aim of breaking your site security. And to get internal information of your site database as much as possible. This plug-in can control SQL injection & base64 attacks till some extension.

Login LockDown - Login LockDown controls number of unsuccessful login attempts. So you ever be safe from brute force & dictionary attack.

WordPress File Monitor - As its name suggest, it monitors all files on your server. This plug-in tells you about what files are changed on your server. So that you can identify whether the mentioned files are changed by you or by some script.

Don’t you ever find any software which can keep records of your software or applications?

Mr das has a huge library of movies and software. But he ever fails to find out the exact software when he needs. He can’t keep everything in his computer because of memory and virus infection. So he is supposed to burn CD, DVDs. But finding out one DVD out of 100, is really time consuming and frustrating job. Finally, he labeled every DVD. And he maintained a database to manage software and movies. He stored all information about which CD keeps which software, in a MS Access file.

Here I am sharing Mr das’s database with you. It contains enough sample data for practice, if you are solving some SQL exercise or building any database project. Otherwise you can use it for use personal use. You can download more database files from here.

It is MS Access file. Either you can burn it with CD/DVD itself. Or you can keep a central copy saved on your PC. In second case, you would have to increase one more column in attached database file for CD/DVD label entry. So you’ll become able to search your important software.

Let’s start

Develop your plugin and test it locally.

Notify WordPress team about your work

a. Create you account on wordpress .
b. Select “Add your plugin” from left menu. Fil basic information about your plugin or theme. So that wordpress team can access it and test it.

Wait for mail
Once your plugin is submitted to and tested by wordpress team you will get a mail. like this

    Your plugin hosting request has been approved.
    Within one hour, you will have access to your SVN repository at 

http://plugins.svn.wordpress.org/YOUR-PLUGIN-NAME/

    with your WordPress.org/bbPress.org username and password (the same one you use on the forums).
    Here's some handy links to help you get started.
    Using Subversion with the WordPress Plugins Directory 

http://wordpress.org/extend/plugins/about/svn/

    FAQ about the WordPress Plugins Directory 

http://wordpress.org/extend/plugins/about/faq/

    WordPress Plugins Directory readme.txt standard 

http://wordpress.org/extend/plugins/about/readme.txt

    readme.txt validator: 

http://wordpress.org/extend/plugins/about/validator/

    Enjoy!

It may confuse you little bit. But forget it

4. Download “Tortoise SVN” from http://subversion.tigris.org/. [you may have to login to download it]

5. Once the installation is done.

1. Create a folder somewhere on your hard disk.
2. Right click on the folder. And select “Create repository here”.
3. Some folders will be created inside the folder you opted for repository.
4. Again right click on the same folder. And select “SVN Checkout”. [To know more in detail you may visit wordpress]
5. It will ask for login ID & Password. Use the id you use to login on wordpress plugin site.

6. Inside your plugin directory you will get three more folders

1. trunk
2. tags
3. branches

7. Copy your plugin files in “trunk” folder.(dont archive them)

8. Make a readme.txt to tell something about your plugin or theme. refer its format.

Note
To check whether contents of your readme.txt are valid or not. Go to read me validator. Here you can paste contents of readme.txt. And can validate it.

Extra files
Providing screenshots to viewers of your plugin is really a good idea. It may fascinate users to use your plugin. Take some screenshot. And place them into “tags” folder of your repository folder. And specify their path into readme.txt.

Note
tags folder contain a version folder like “/2.0/”. All files are placed only inside version folder. This version must be similar to the version specified in you readme.txt

Save your work

What else. Just right click on your repository folder and select “SVN Commit”. Your work will be uploaded to wordpress server. You may check it by following http://plugins.svn.wordpress.org/YOUR-PLUGIN-NAME/

You may also refer my repository directory structure for further help.

Most of the video chat program requires webcam at both sides. If your friend wanna chat with you then both of you require webcam. Many of the chat programs let you chat but many of them limit you. This trick is just to bypass all limitations. For this you must have to learn how to share your PC with your friend over internet.

Now you can share your files with our friend. You can watch movie on his PC (require good speed internet connection) or can see him through his webcam itself.

It is very easy to share your PC with your friend without doing any settings. You just need to download Teamviewer on your PC. Once you had downloaded it.

1

Run Teamviewer installer file. It’ll ask you whether you want to install it or want to run it directly. Select RUN > Next. And Accept their agreement. See in below image.

2

Once you select RUN, it’ll give you an ID & Password that you can share with your friend. Otherwise ask your friend for the same. Take his ID and enter it into blanked ID box (appears in right side of below screenshot). You can notice into below screen shot. Click on “Connect to Partner” button.

Trouble shoot:

1. If TeamViewer is not generating ID & Password then might be your firewall, installed on your PC, has denied it to connect over internet. You’ll have to remove it from firewall’s entry. Or You will have to set its rule to ALLOW.
2. Might be Teamviewer is still trying to connect. Check whether you can see RIGHT sign symbol in left bottom of above screen shot. If not then have patient.

I seen people searching software or plug-in to save more than once images from a web page in one short. Or they manually right click on the image and save it. But if you are using Firefox then this tip can save your time & effort both. It’ll also help you to save embedded videos and background image of that page.

Generally, Background images are not saved when you save a web page.

Well!! First you need to visit that page from Firefox browser. Once it is opened. Go to TOOLS menu & select Page Info.
You’ll get a dialog box on your screen. This will give you some information about opened web page. You can see four tabs in that dialog box. GENERAL tab fetches information from page header. It arranges information and displays them properly. So you can read & understand it properly.

Next is MEDIA Tab. All embedded contents and images are listed here. You can select anyone of them to see their preview. You’ll find a “Save As” button o the preview area, to save selected item. You also can select multiple items from the list. And save them.

This is a very good example of visual basic macro. If you use outlook in your office or at home this code will surely save your time. This code is suggested by my friend Prathamesh Raorane.

This area is protected to registered users only.

To use above code.

Open Outlook [I tested the above code in Outlook 2003 & 2007]
Press Alt + F11. Otherwise go to Tools menu and select macro option.
Open the macro editor.
Copy paste above code. And save it.
You may add a toolbar button. So from the next time you can run the code directly from the toolbar. Otherwise you’ll have to go to Tools > macro every time.

Once everything done then every time when you run the code will open separate window similarly when you click on “reply to all” button. List of attachments will be retained this time.

Special Thanks to Prathamesh Raorane

Well!! You’ll find many of valid invalid circumstances where you need to open locked folder & files. Here I am explaining how can you break any folder/ file security software without having any technical or hacking knowledge. Most of the techniques are applicable only on PC SECURITY software. But some of them you can apply on other locking software as well.

Yesterday while writing an article over how to hack PC Security? & How to hack winzip? i committed spelling mistake. I found that MS Office 2007 was not having any perfect solution for that spelling as you can find in given screen shot. But when i searched for right word in wordweb, i found single & correct spelling.
