Open Command Prompt in any folder in windows

We all know that Command Prompt is essential in performing many tasks in our day to day life.For example we have seen previously that to retrieve hidden files from USB Drives,we are using command prompt and also for removing write protection in USB Drives and also for hiding text in notepad.

But every time opening command prompt through run command (Win + R -> cmd) and navigating to our necessary folder by typing commands like cd for changing directories,md or mkdir for creating directories.Also,if someone is doing project,they want to shift to that directory using command prompt for execution.

Hold shift key and right click the mouse in the folder in which one want to open command prompt,then one can see the option of  open command window here.

You don't need any software or registry edits to perform this task.



Another way to open COMMAND PROMPT is to Go to address bar in any folder and type CMD and hit enter. You are done, Command prompt opens there.

This way one can save time in typing the commands or it will be helpful to those who are not familiar with cmd commands. You can also look like computer geek by using keyboard and working fastly with keyboard shortcuts.

Have your work completed faster.... :)

Useful Notepad Tricks

Know System time using notepad :

Many of us use notepad to write programs or write some to-do lists. Some people hide their taskbars in order to reduce the distraction.We might want to know the current time as we have been coding from a long time.Also suppose we dont want to move our hands from the keyboard or we operate the computer using shortcuts or keyboard only.

You need not worry about moving your mouse upto taskbar and let it pop up. You can simply press FunctionKey (F5) while you are in notepad to know the system time.



Hide text in notepad :

Sometimes we may want to send some confidential data to our friends.Previously we have seen a post how to send it using privnote.

But sometimes we want to send some important matter and we prefer sending it through notepad.But others can easily see it by just opening it.

Here is a method by which you can hide the contents of notepad.


  • Open command prompt (Win + R -> cmd)
  • Go to your select directory
  • type notepad filename.txt: hidden
  • Save the file
There should be no space between filename.txt and :
Now open the file and you can see that the content is hidden and also the properties show the file size as 0 Bytes

To open the file,follow the same steps by going to command prompt.

ThankYou :)

Send Files or Messages to any computer in a network

Many of us have computers with us and also with our friends.Most of us share music,movies,photos from tour with each other.

Each time we are going to copy them to a USB Drive and give it to other people for them to copy even if they are adjacent to us.But some times they get affected by virus and gets converted into shortcuts.We have already discussed how to retrieve files from USB drive with shortcuts.

But each time copying them to USB Drive and giving to other person takes lot of time.Instead we can share the files to a particular computer in a network with a single click.

IP Messenger is a software that lets you share files in a network with very high speed as similar to USB Drives.It has a very simple interface and best performance.







Click on reply to give reply message





 Suppose you and your friends are on your college wifi,you can send the files to your friends wherever they are.Even this software lets you send messages to chat with people on your network.The messages will be directly delivered to the computer.

Suppose you are on you Home Wifi connection then also you can share the files or send messages.

  • Highlight a computer name and type text and lick on send to send message to computer
  • Click on screen icon at left bottom to capture screen area and send it to another computer
  • Click on dropdown button below refresh button to get options for file transfer
  • It also has the capability to directly send prtscn (Print Screen) screenshots by directly pasting screenshot in text area
Both the parties need to have the software to send the messages or file transfer.

The software size is very less around 592KB.

NOTE : Press Refresh button for every transfer of file (before sending) to avoid Sending Failed message.



Happy File Sharing....!

Pwn2Own : The greatest Hackers Reward Program

Pwn2Own is a computer hacking contest held annually at the CanSecWest security conference, beginning in 2007. Contestants are challenged to exploit widely used software and mobile devices with previously unknown vulnerabilities. Winners of the contest receive the device that they exploited, a cash prize, and a “Masters” jacket celebrating the year of their win. The name “Pwn2Own” is derived from the fact that contestants must “pwn” or hack the device in order to “own” or win it. The Pwn2Own contest serves to demonstrate the vulnerability of devices and software in widespread use while also providing a checkpoint on the progress made in security since the previous year.



Contest dates for the year 2014:

The contest will take place March 12-13 in Vancouver, British Columbia, at the CanSecWest 2014 conference. The schedule of contestants and platforms will be determined by random drawing at the conference venue and posted at Pwn2Own.com  prior to the start of competition.

Prank to Restart your Windows Computer repititively

We all know that we can shutdown or restart any computer by executing simple run commands.
But how would it be if we are going to use the same commands to do something unnatural altering your computer's performance.

We are going to use the run commands to play a prank on a computer to automatically shutdown after booting or restart after booting.

We achieve this by writing a simple batch file. A Batch file (filename.bat) is a file  containing instructions that are directly executed on command prompt. So we keep the instructions that we want to execute in a simple notepad file and going to save it with some file name. Now our work is to place the file into startup folder of your windows operating system.

Steps to follow:

  1. Open notepad
  2. copy and paste the follow the following code in bold letters
@echooff
shutdown -r -f -t 300 -c "Message"

In the above code -r stands for restarting, -f for force shutting down the computer, -t for time in seconds, -c for comments where in you can embed your own message to surprise your friend.

Instead of -r attribute, -s can be used to shutdown the computer.

Now save the file as shutdown.bat and place it in the startup folder of your computer. The items in startup items will be run automatically whenever the computer starts.

DOWNLOAD THE FILE FROM HERE

Startup item locations:

  • WINDOWS XP : C:\Documents and Settings\(user)\Start Menu\Programs\Startup
  • WINDOWS 7 & 8 : C:\Users\(User-Name)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

To remove that startup item you may have to go to same folder and delete it. So, be careful when giving the time attribute and give appropriate time so that you can navigate to that folder and remove it. Else you have to restart your computer in safe mode and remove that file.

Thank You :)

Improve Web Browsing Experience with OneTab for Chrome

We all browse internet everyday for exploring information and we go through a lot of websites and in addition we are logged into our social network accounts like Facebook , Google + .

After opening a no of tabs in our browser the memory used by it increases and the browser slows down. But actually we will be on a single tab any instance of time.

OneTab is an extension for chrome that groups all the opened tabs into a single tab in a list form. By this it reduces almost 95% of memory used by web-browser.

As tabs are grouped into a single page as list , no scripts will be running when in background. This also improves the performance of your system when it is resuming from sleep mode.

You can also share all the links as a webpage instead of copying and pasting each and every link !!!!!!

It is free and no signup is required. Your data is not sent anywhere. So you need not worry about privacy.


OneTab Extension for Chrome



Hope this post helps improving your browsing experience... :)

Euclidean Algorithm to compute GCD of 2 numbers

Euclidean Algorithm

Here we assume that a is greater than b

(a>b)

gcd_euclid(int a, int b)
{
         if( b is 0) return a
     
        else
            {
              set value of a as b
              set value of b as a modulo b
            }
}

When 2 prime no's are taken,GCD is usually 1 and it can be seen from below example.... 

  1. gcd_euclid(19,5)
  2. gcd_euclid(5,19%5)
  3. gcd_euclid(5,4)
  4. gcd_euclid(4,5%4)
  5. gcd_euclid(4,1)
  6. gcd_euclid(1,4%1)
  7. gcd_euclid(1,0)
return 1; //as b is 0.



GCD when 2 non prime no's are taken.....

  1. gcd_euclid(30,5)
  2. gcd_euclid(5,30%5)
  3. gcd_euclid(5,0)
return 5; // as b is 0


Programmatic Implementation:

int euclid(int a, int b)
{
   while (b!=0)
   {
       int temp = b;
       int b = a%b;
       int a = temp;
   }

return a;
}

Thank You :)
