Need Applescript to lock computer

[Mulan]

Hi, basically i am a Windows Xp user but recently have bought a new pc with Snow Leopard. Am not much familiar with OS yet but liked it. Now as we lock the computer in Windows with the key Win + L, i wanted to do similar in MAC as well. Some friends suggested me to go with Applescript for the same. So, could you guys please let me know where can i get that Applescript ? Also let me know some info about the same. Thanks in advance.

AppleScript is a scripting language created by Apple , and integrated with Mac OS . It is known to possess a rich and elaborate syntax, the closest as possible to a limited pseudo-English. More generally, AppleScript is the word that means the script interface of Mac OS, which is designed to operate in parallel with the graphical environment . It was designed to offer users a smart control applications, information and documents and thus implement an automated management tasks. Automate tasks with AppleScript reduces the time it takes to accomplish these tasks and reduce opportunities for human error.

Here is the Applescript that i have taken from one of my friend using Mac os x:

activate application "SystemUIServer"
tell application "System Events"
    tell process "SystemUIServer"
    	repeat with i from 1 to number of menu bar items of menu bar 1
    		tell menu bar item i of menu bar 1
    			click
    			try
    				if name of menu item 1 of front menu is "Lock Screen" then
    					click menu item "Lock Screen" of front menu
    					exit repeat
    				end if
    			end try
    		end tell
    	end repeat
    end tell
end tell

Hope it works.!

Well, alternatively we can activate the screensaver and set it password to end the same. It is also like locking the screen of your MAC system. Here is how to do that:

do shell script "open /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ScreenSaverEngine.app"

A major concept is that the AppleScript scripts handle applications in a way fundamentally different from the way users interact with them. The user uses the application through the GUI by selecting options in the menus and clicking buttons, so that scripts request and define the values and actions invoked by the application in internal mode. For example, instead of simulating keystrokes to enter text into fields of application, using AppleScript commands directly fixing the values of the desired fields of the record, even without the application

In Mac OS X , AppleScript is easier to implement by the developers, particularly for applications developed in Cocoa . Unlike Mac OS where the events are handled by applications in Cocoa, events are decoded high-level command by the subject NSApplication , and messages addressed directly to the correct object. Every Cocoa application is "refactored" by default, the developer who (normally) to write the code for handling events but only the "methods" that will be called by these events.

To designate which application is referred by the message, AppleScript uses the verb ""tell"" (said):

 tell application ""Microsoft Word""
   quit
 end tell

This same application can be written in one line using the verb in the infinitive:

 tell application ""Microsoft Word"" to quit
