JavaScript Tricks: Edit Websites in Browser (Live)

Imagine a world where you are a God and have ultimate control on what happens and more importantly, how it happens. Seems too good a dream. Now it has come true, at least for the online world.

Edit Websites Browser

Using this trick, you will be able to edit any webpage live in your browser as if it was a Wiki and change the details according to your wish. Yes, you read that right. You can edit Google or even Facebook for that matter right in your browser and that too without requiring any technical know-how or getting deep into hacking and cracking.

Here is an example picture demonstrating the Google Homepage edited by me to say that I own Google.

This is just an example. You can use it for anything like showing wrong traffic stats or for fooling people by showing that someone said something about them on Facebook or Twitter. It depends only on your creativity. But I would advise you to stay ethical and use it for entertainment purposes only.

(Mozilla Firefox does not support this. If you use Firefox, you can use the bookmarklets given at the end of this post. If you use Google Chrome and the code does not seem to work, precede it with "javascript:" without quotes.)

To use this trick, all you need to do is just copy the code given below and paste it in your address bar [make sure its in single line] after you have opened the website you wish to edit. And start editing.

javascript:document.body.contentEditable%20=%20'true';
%20document.designMode='on';%20void%200

You can capture a screenshot by pressing the Print Screen key or by using the Snipping Tool if you use Windows 7 or Windows Vista. If you wish to again make the website non-editable to give a more authentic look, copy and paste the code given below in the address bar [make sure its in single line] after you are done editing (does not work in Firefox).

javascript:document.body.contentEditable%20=%20'false'; 
%20document.designMode='off';%20void%200

Or, alternatively you can use the following bookmarklets by dragging them to your Bookmarks bar.
The editing that you do will however be temporary as it is not server-sided. You can also save the modified website through your browser by File>Save. This works on all common web browsers including Chrome, Firefox, Opera and Internet Explorer.

Transfer Files Between Devices & Your Windows 7 PC via Bluetooth

Bluetooth devices are very common nowadays. By using this technology it is so easy to share files between very different devices. If your computer or laptop has a Bluetooth dongle or built-in module, Windows 7 can use it for exchanging files with other Bluetooth enabled devices such as mobile phones, iPods, iPhones, PSP devices, etc. In this guide I will show you how to verify that your dongle or built-in module works, how to connect your computer to another Bluetooth enabled device and how to exchange files between them.


Verify that Bluetooth is Working Correctly

The first thing you should do before starting a Bluetooth connection is to make sure that the Bluetooth dongle or integrated module is inserted in the computer and turned on.
Windows 7 will then install the drivers needed for the Bluetooth device. It has drivers for most Bluetooth dongles and built-in devices but, if it's not able to find any suitable drivers for it, then you should install those which are bundled by the manufacturer of your product via an install disc or on its official website.
Next, you will see a Bluetooth icon in the system tray or notification area which means that Bluetooth is active.

Bluetooth

If it is not active, you'll have to enable Bluetooth on your computer. By default, the wireless and Bluetooth connections are active. If, for some reason, they're not, look for a button on the surface of your laptop that should enable both wireless and Bluetooth connections. If you can't find that button please read the laptop's manual to find it and learn how to turn on Bluetooth.
Now, you need to make sure that the Bluetooth works properly. Type in the Start menu search box the word bluetooth and click on the 'View devices and printers' search result. Another way is to go to 'Control Panel -> Hardware and Sound -> Devices and Printers'.

Bluetooth

In the new window you will see a list with all devices and printers that are connected to your computer. The Bluetooth dongle or integrated module will be on that list as well. If your Bluetooth device has a yellow exclamation point on its icon it means that there is a problem with it. Otherwise it means that the device is working properly.

Bluetooth

If the device has problems, select it and then click on the Troubleshoot button from the top menu. Follow the wizard's instructions and hopefully, Windows will find a solution to the problem.

Bluetooth

NOTE: If the device that you want to connect via Bluetooth to your computer has specific software applications made exactly for this kind of task, I recommend you to use that software. For example, if you have a phone with Bluetooth support it is a good idea to use that phone's "PC Suite" application on your computer.

Connect a Device to Your Computer Using Bluetooth

First you need to make sure that your computer can be seen by the Bluetooth device. In other words, you need to make sure the computer is discoverable via Bluetooth. You can access the Bluetooth settings on your computer by right-clicking the Bluetooth icon in the system tray or notification area, and selecting 'Open Settings'.

Bluetooth

Or you can simply search in the Start Menu's search box for bluetooth and click on the 'Change Bluetooth settings' search result.

Bluetooth

The Bluetooth settings window will now open. In the Options tab, at the Discovery section, check 'Allow Bluetooth devices to find this computer'. This will allow other devices to see your computer. When done, click on OK.
NOTE: Enable this option only if you want the Bluetooth device to find and connect to your computer. The other way around, connecting from the computer to the device, works without having this option enabled.

Bluetooth

Next, you have to activate Bluetooth on your device. Search for discoverable devices, select the computer and pair with it. Then you have to enter a password for this connection. On your computer you will see a system notification about a device that wants to connect with it. Click on that balloon or, if you missed it, double click on the Bluetooth icon from the system tray or notification area.

Bluetooth

In the new 'Add a device' window you have to type the same password as you did in in the device that is connecting to the computer. Then click on Next.

Bluetooth

Now Windows 7 will search for drivers and it will install them for the device that is connecting to your computer. To verify that the device has been properly installed click the Devices and Printers link from the 'Add a device' window.

Bluetooth

There you can also see if the device is working properly or if it requires troubleshooting.
NOTE: If Windows doesn't find suitable drivers for the Bluetooth Peripheral Device, don't worry, you will still be able to send and receive files.

Bluetooth

Now, assuming that there are no problems, let's see how to send a file from the device to the computer through Bluetooth.

Connect the Computer to a Device Using Bluetooth

Turn on the Bluetooth function on the device and make it discoverable so that your computer will find it. Then open up the Bluetooth device window either by double-clicking the Bluetooth icon from the system tray or notification area. Click on the 'Add device' button or simply search in the Start Menu's search box for bluetooth and select the 'Add a Bluetooth device' result.

Bluetooth

Next Windows 7 will search for Bluetooth enabled devices. When it finds your Bluetooth device, select it and click on Next.

Bluetooth

Then Windows 7 will show you a password or PIN that you have to type in the device. After you typed the PIN in your device, click on Next.

Bluetooth

Now you can see the newly added device in the Bluetooth Devices window. There you can also see if the device is working properly or if it requires troubleshooting.

How to Send a File via Bluetooth

In order to send a file either right-click the Bluetooth icon from the system tray/notification area and select the 'Send a file' option or search for bluetooth in the Start Menu's search box and click on 'Bluetooth File Transfer'. Then select the 'Send a file' action.

Bluetooth

Now select the device to which you want to send a file from the computer and click on Next. In the next window, click on Browse to select the file that you want to send and then click on Next.

Bluetooth

Tip: Hold down the Shift or Ctrl key to select multiple files.
You might need to allow the transfer on your device as well, and only then the computer will connect with it and it will send the file. In the next window you will see a summary of the files that were delivered to the device through the Bluetooth connection. Click on Finish to exit the window.

Bluetooth

If you want to send other files, repeat the same steps as above.

How to Receive a File via Bluetooth

In order to receive a file from the device to your computer, you can either right-click the Bluetooth icon from the system tray or notification area and select 'Receive a file' or search for bluetooth in the Start Menu's search box and click on 'Bluetooth File Transfer'. Then select the 'Receive a File' option.

Bluetooth

Windows 7 will wait until you select a file on your device. Select the file to be sent to the computer through the Bluetooth connection, wait until the device finds the computer, select it, and then your computer will receive the file. In the next window you will see the name and the size of the file and you have to possibility to choose where to save it. Click on Browse to choose a different location than the default one and then click on Finish.

Bluetooth

The file is now received and stored in the location you selected.

Conclusion

As you can see, sending or receiving files through a Bluetooth connection is quite easy, even if some problems can happen. The lucky part is that the troubleshooting wizards are definitely better at offering solutions then those from Windows Vista and, when using them, you will get some good solutions to your problems.

The wide range of devices that have support for Bluetooth can be a disadvantage because Microsoft can't collect and deliver driver support for every product that has Bluetooth capabilities. That's why every topic about Bluetooth connections between devices and computers is full of people complaining about problems with the connection, drivers or anything in between. If you have problems, solutions or you know some great tips and tricks about Bluetooth connections don't hesitate to share them with us in a comment.


Connect two Computers using Cross Cable

 
Sharing the high Disk Space file between two computer is littel bit of difficult incase you don’t have high GB pen drive. Many use LAN Cable to connect the two computers but they can’t.

Here I bring you to How to connect two computers/Laptops using LAN Cable. so that you built your own network to share files, play counter strike, and much more…

Basic things required while building up a network are
LAN Cable with rj45 connectors
Computers/Netbook between the networking is to be done.

RJ45 is basically called as Register Jacket. It is a piece of plastic bound with different types of wires in a particular and sequential range for the purpose of running of different of different applications. This jack helps to enable you to ping with the other node.

We do networking by using TCP/IP ports. Each computer have its individual IP address. IP address are basically classified in 3 types A, B, C ranging from 1 to 225.

Class A – 0 to 127
Class B – 128 to 191
Class C – 192 to 223

Here are step which can help you to built a network at your home on your own.
  • The First and the basic step before setting up a network is to check whether LAN drivers are successfully installed on both the computers.
  • Insert the cable in connectors on both computers.
  • Go to Start>Control Panel>Network Connections>right click on Local Area Connection>properties>(TCP/IP)>properties.
  • Click on “use the following IP address“.
  • Remember you have to put IP addresses ranging from 1 to 254 only.
For instance you can put the following setting in first PC
IP address: 192.168.1.1
Subnet mask: 255.255.255.0 (appear default)
Default Gateway: Leave blank



Follow the same steps for the second PC but here you just have to change the IP address, for instance you can keep it 192.168.1.2 and other two kept same.




Save the settings for both the computers. To test whether both computers are connect we ping the each other IP. If you get a reply, then your network is setup successfully.

All are set, know enjoy sharing and gaming.

What ISO Files Are - How to Open and Use Them

Files with the extension ISO are a commonly used file type but I get a lot of inquiries from PC users who do not know what an ISO file is or what to do with one. If you are puzzled by ISO files, here’s what they are all about.

ISO files are simply a way of packaging a lot of files and folders together into a single file with the file extension ISO. They are generally used to create an image of a CD or DVD. Having just one file containing everything is convenient for downloading or for storing on a computer. It is becoming common to distribute programs this way instead of providing physical media. As fewer devices are coming with optical drives, you are likely to encounter ISO files more and more.

A major reason that many average PC users have trouble with ISO files is that Windows XP and Vista do not recognize them natively. If you try to open an ISO file in these older versions of Windows, they do not know what to do with it unless you have installed some third-party software to manage ISO files. However, Windows 7 does have a feature to burn ISO files to a CD or DVD.
Burning ISO files to a CD/DVD

One way to make use of ISO files is to burn the file to a physical CD or DVD disc using a process that extracts all the individual folders and files out of the ISO file and places them on the physical media. Windows 7 comes with the built-in Windows Disc Image Burner (not in earlier versions of Windows). Place a blank CD or DVD in your optical drive and double-click the ISO file. Once the disc is burnt, you can use the files and folders the usual way.

Many PCs also come with third-party software for burning discs. If one of these opens when you double-click an ISO file, choose “Burn disc image” or similar command.

There are also free programs for burning CDs or DVDs. 

Mounting an ISO file to emulate a disc

Often it is not necessary to actually burn a physical disc. It is becoming more common to use ISO files directly. Some older programs will only recognize an external disc and if that is the case you can mount the ISO file so that it appears to be on a separate drive.


Reading the contents of an ISO file without unpacking it


Some applications can read an ISO file as if it were a disc. For example, virtual machines can install Windows operating systems straight from the ISO without unpacking it. It is also possible to read contents of an ISO file with the archive program 7-Zip. It’s analogous to reading the contents of a ZIP file. 


Unpacking an ISO file directly to the hard drive or USB drive


It is also possible to use 7-Zip to extract all the files and folders from an ISO file and place them in a folder on the hard drive or on a USB drive. Just use 7-Zip in the same way as with regular archive files. There are also programs like IsoBuster. 

And there you have it – ISO files don't have to be a mystery any longer.
