In the previous post, I have already described about "How to Loop Through JavaScript Array". Along with accessing an element of an array using looping statements, you can also concatenate, join and sort an array in JavaScript. In this post you will learn about How to Concatenate, Join and Sort Array in JavaScript.

Using concat() method, you can join to arrays array1 and array2 as below.

Here the method array1.concat(array2) concentrates two arrays array1 and array2.

You can use the join() method to put all the elements of an array into a string as the following script.

<script>

var array1=new Array(3);

array1[0]="Yamaha"

array1[1]="Honda"

array1[2]="Bajaj"

document.write(array1.join()+"<br/>");

document.write (array1.join("."));

</script>

Using sort() method, you can sort the elements of string array as given below.

<script>

var array1=new Array(6);

array1[0]="Saab"

array1[1]="Volvo"

array1[2]="BMW"

array1[3]="Yamaha"

array1[4]="Honda"

array1[5]="Bajaj"

document.write(array1+"<br/>");

document.write (array1.sort());

</script>

Using sort() method, you can sort the elements of numeric array as given below.

<script>

var array2=new Array(6);

array2[0]=10

array2[1]=5

array2[2]=40

array2[3]=25

array2[4]=35

array2[5]=95

function sortNumber(a,b) {return a - b;}

document.write(array2+"<br/>");

document.write (array2.sort(sortNumber));

</script>

There are also other more methods for manipulating array elements, which are listed below along with their description. You can use them as the methods given above.

Windows 7 operating system supports multiple user accounts creation, either as administrator or standard user account type that can be allocated in addition to a guest account.

But after an account is created, it can only be deleted or removed and administrator can not disable or turn off the user account from the Control Panel user interface. Administrator must disable may be temporarily or permanently, or disable a user account without deleting it or removing the user’s account completely from the system.

To turn off or disable user account, follow the following instructions. Disable a user account, you can activate or reactivate the account again in the future without loss of data.

Tip: Uncheck the Account is disabled option to re-enable the user.

Alternative method is to use command line syntax of “net user”. To disable and make a user account inactive, open an elevated command prompt with administrator rights, and type the following command:

Replace user name with the actual user name of the account to disable. Note that user name with space in between must be enclosed with quotation mark (“).

To reactivate the account to active status, just use the following command, as similar to enable the built-in super administrator account in Windows 7 and Vista:

Searching feature in windows is one of the greatest advantage.It lets you access your files quickly and easily without you peeping into different folders one by one.It very useful when you have forgot the place of the file or the exact name of the file.Have you ever wondered how this search option is powered or built.It is actually built or powered by Indexing in Windows just like an index of a book.But here in windows you can choose the location to include or exclude in indexing.Or you can delete or add entry or remove old unavailable entry or rebuild the whole index to optimize the search feature for enabling the fast searching.

What is Index? 

A collection of detailed information about the files on your computer.
Windows uses the index to perform very fast searches on your computer. Here are some advanced indexing settings you can change.

What files are indexed?

By default, all of the most common files on your computer are indexed. Indexed locations include all folders included in libraries (anything you see in the Documents library, for example), e?mail, and offline files. Files that arent indexed include program files and system files—files that most people rarely need to search.

Can I index my entire computer so all searches are fast?

You shouldnt do this. If you make the index too large, or if you include system file locations (such as the Program Files folder), your routine searches will slow down. For best search results, we recommend that you only add folders that you search frequently to enable fast searching.

How to fix Searching and Indexing issue

1. To add a file type to the index

3. To index encrypted files for searching encrypted files too

Before you add encrypted files to the index, we recommend that you have Windows BitLocker (or a non-Microsoft encryption program) enabled on your system drive (the drive that Windows is installed on).

Note:Windows BitLocker is only included in Windows 7 Enterprise and Windows 7 Ultimate.

Note that the index will automatically rebuild each time this setting is changed. This can take a long time, and might cause searches to be incomplete until the process is complete.

• Go to Control panel and then open Indexing Options.
• Click Advanced.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 
• In the Advanced Options dialog box, click the Index Settings tab, select the Index encrypted files check box, and then click OK.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 

Notes
Although you can use a non-Microsoft program to encrypt your system drive, non-Microsoft file encryption programs are not supported. Windows only supports files encrypted using Encrypting File System (EFS).

EFS is only included in Windows 7 Enterprise, Windows 7 Professional, and Windows 7 Ultimate.


If you add encrypted files to the index and youre not using full-volume encryption for the location of the index, encrypted data from your files for example, text from an encrypted Microsoft Word document will be added to the index and will be available for searching. The index is obscured so that its not easily readable if someone tries to open the index files, but it doesnt have strong data encryption. If someone were to gain access to your computer, they could extract your data from the index. Therefore, the location of the index should also be encrypted to help protect your indexed data.

4. To index words with and without diacritics as different words

If you commonly use diacritics (small signs added to letters to change the pronunciation of words) in your file and folder names, you can configure the index to recognize words with diacritics differently. By default, Windows recognizes diacritics according to the language version you are using. If you change this setting, all diacritics will be recognized.

The index will automatically be rebuilt each time this setting is changed. This can take a long time and might cause searches to be incomplete until the process is complete.

• Click to open Indexing Options. 
• Click Advanced.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 
• In the Advanced Options dialog box, click the Index Settings tab. 
• Under File Settings, select the Treat similar words with diacritics as different words check box, click OK, and then click OK again.

5. To change the location where the index is stored

If you need to free up space on a hard disk, you can change the location of the index. If you change this location, the Windows Search service will automatically be restarted, and the change will not go into effect until the restart is complete.

• Click to open Indexing Options. 
• Click Advanced.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 
• In the Advanced Options dialog box, click the Index Settings tab.

• Under Index location, click Select new, click a new location, click OK, and then click OK again.

Note
When you change the index location, you should choose a location on a non-removable hard disk that is formatted using the NTFS file system.

What does it mean when I see a message that search results might be incomplete?

It means that the files are still being indexed. To perform fast and accurate searches, Windows collects information about files on your computer. This information is stored in the index. Periodically, Windows needs to update the index. If you perform a search while the index is being updated, the results might be out of date.

What does it mean when I see a message that a location cant be searched or theres no media present in the search location?

Theres a problem searching one or more of your selected locations. Usually thats because youve selected a network location or a device thats not currently connected to your computer. Its also possible that youve selected a removable media device with no media (such as a memory card or a CD) in the device. Check your locations, and then try the search again.

How do I troubleshoot problems with searching and indexing?

If you are experiencing problems with searching, such as unusually slow searches or incomplete search results,or no search results at all run the Search and Indexing troubleshooter to see if it can diagnose the problem.

• Go to control panel and open Troubleshooting.
• Click on System and Security.

• Now Click on Search and Indexing.
• Its gonna ask the problem you are facing so select the problems and click next to troubleshoot and fix.
