10 Quick Fixes to Make your Windows Computer Faster

Quick Fixes to Make your Windows Computer Faster Your computer running Windows isn’t running in the same speed that it used to run when you first used it. It’s slower, crappy, takes a while to start and tests your patience like anything. There are many reasons for this, let’s try fixing up a few things on your slow Windows PC: Slow Start Up There can be a variety of reasons to Windows loading slow during start up. Go to Run, type msconfig and hit enter. Under the ‘Start Up’ tab, uncheck the unwanted programs and press OK. Things should be a bit fine the next time Windows boots. Another program worth mentioning here is StartUp Delayer which will help in setting after how much time programs should be loaded after Windows boots. For instance, you could set your instant messenger program to load 50 seconds after Windows starts up. Slow Loading Start Menu If the Start Menu items are loading slowly, you can open the Registry Editor by typing in the Run menu ‘regedit.exe’ and pressing Enter. Go to HKEY_CURRENT_USERControl PanelDesktop. Look for MenuShowDelay, and double click to edit the value. The lower the number specified, the faster the Start Menu will load. Slow Right Click Context Menu Probably the Windows Right Click menu on your computer is loading slow because too many programs added unwanted entries there. Just download this program called Mmm, install it and then modify your context menu to remove unwanted items to speed it up. Slow Send To Menu If the Send To menu loads slowly, you can type ‘sendto’ in the Run Dialog, and remove unwanted items in the Explorer Window that appears. This should add some speed to it. Slow Defragmentation The Windows Defragmenter can’t get any slower. You need to have an alternative to the Windows Defragmenter, and Defraggler is just one of the best ones available in the market. It’s free, and works like a charm and can speed up defragmentation manifold. For some alternatives, see Five Free Programs to Defragment your PC. Slow loading My Computer Window If the My Computer Window loads slowly, in the Explorer Window, go to Tools >> Folder Options >> View and uncheck ‘Automatically search for network folders and printers” Slow loading Add or Remove Programs Applet This is one of the most annoying piece of programs present in Windows, it takes ages to load if you have a considerable number of programs installed on your computer. You can either use the all-in-one CCleaner for this purpose, or get MyUninstaller that comes as a speedy replacement for Add or Remove Programs. Slow Ending of Unresponsive Programs If you’ve clicked on ‘End Task’ if any program is running unresponsive, you might have noticed that the program is not terminated immediately. You can alter this by going to Run >> regedit.exe >> HKEY_LOCAL_MACHINESystemCurrentControlSetControl and change this value to 1000. Disable Animations and Appearance Overhauls to maximize performance If you’re a serious performance junkie, you probably won’t bother about eyecandy. Go to System Properties in the Control Panel. Click ‘Advanced’, then ‘Performance’ and click ‘Adjust for best performance’. This might boost your PC’s performance up a bit. Additional Tips: - Always keep your computer clean. Remove Junk and Unnecessary registry entries. Use CCleaner for this purpose, one excellent tool that just does what it says. - Don’t keep installing software. Install a program only if it really serves you a purpose. - Keep as less programs as possible running on the System Tray. This essentially means reducing the

Introduction to JavaScript

Get acquainted with JavaScript Outcome: Students will learn what JavaScript is, where to put scripts in an HTML document and how to write simple scripts. Objectives: 1.1 JavaScript vs Java vs HTML, automatic & triggered scripts 1.2 Where to put your scripts in an HTML document 1.3 How to hide scripts from old web browsers 1.4 How to put comments in scripts 1.5 Alert boxes 1.6 Confirm & Prompt boxes 1.7 Calling functions with a button - MCQ assignment 1. What is JavaScript and how is different from JAVA and HTML? see table 2. Types of JavaScript Client side - runs in browser Server side - runs on server - embeded in web page but processed on server 3. Scripts can run automatically or be user triggered 4. Placing Scripts a) in Head tag - this prevents user triggered errors during downloading b) in body - including within body tag as an attribute c) within forms as Event handlers - script tag not required 5. Can be copied from web page code can be copyrighted JAVA Developed by Sun Microsystems James Gosling 199(originally called Oak changed to Java 1993) True programming compiled to bytecode (not machine code) platform independent Object oriented - can create their own classes Currently version 1.2 Requires machine specific interpretor or can use a web browser fully extensible i.e. has unlimited no of objects including classes with inheritance case sensitive can be used for client server interaction In web pages - Applets can not be copied from web page - user must make program available code can be copyrighted 6. Comment TAGS HTML JavaScript // single line comment /* multiple line comments */ Adding comments to your script is very important so that you and others know what the various components do especially if you examine the script after several months. Netscape 1.0 does not support JavaScript Internet Explorer 2.0 earlier does not support JavaScript Some other browsers including most WYSIWYG HTML editors do not support JavaScript Make sure you view scripts in both major browsers to see if it works! 7. Dot Syntax document.write() document = object write() = method something the object does object. property.method() Hierachy window is the top not necessary to include window.document.write() window.alert() Note JavaScript is case sensitive! 8. Parenthesis " " or ' ' double or single can mix " ' " " always pair properly "" says treat as a literal value 9. Braces - Chicken lips - used with functions { { } } 10. Outputting to Screen (Can not send to printer) document.write("Hello World") document.writeln("Hello World") l is small letter L need

 tag before and script tag to work
Can include HTML tags inside
document.write("
Hellow World")
Need to use 
 or 
 tag to move to next line
Can also use \n
see Chapter 2 page 14
11) Alert boxes - see Chapter 2 page 17 - Negrino Book.
alert("message")
automatic alert by placing in  tags
top object is window.alert("message") not necessary to include window
user triggered alert by placing in form button using no script
tags just event Handler onClick="alert('message')" and form
note use of two "" '' parenthesis
Then create a function saySomething() activate with a
button - this will be the basis of homework assignment.
CAUTION: when using notepad to input code do not place a carriage return inside a JavaScript
statement or line of code - it will not work! Also make sure you add the .html extension to the file
name when saving your scripts in web page.
12) Confirm(" Question")

Enable Remote Connection on SQL Server 2008 Express

If you’re trying to connect to SQL Server 2008 Express remotely without enable remote connection first, you may see these error messages:

* “Cannot connect to SQL-Server-Instance-Name
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 28 – Server doesn’t support requested protocol) (Microsoft SQL Server)”

To enable remote connection on SQL Server 2008 Express, see the step below:

1. Start SQL Server Browser service if it’s not started yet. SQL Server Browser listens for incoming requests for Microsoft SQL Server resources and provides information about SQL Server instances installed on the computer.
2. Enable TCP/IP protocol for SQL Server 2008 Express to accept remote connection.
3. (Optional) Change Server Authentication to SQL Server and Windows Authentication. By default, SQL Server 2008 Express allows only Windows Authentication mode so you can connect to the SQL Server with current user log-on credential. If you want to specify user for connect to the SQL Server, you have to change Server Authentication to SQL Server and Windows Authentication.

Note: In SQL Server 2008 Express, there isn’t SQL Server Surface Area Configuration so you have to configure from SQL Server Configuration Manager instead.
Step-by-step

1. Open SQL Server Configuration Manager. Click Start -> Programs -> Microsoft SQL Server 2008 -> Configuration Tools -> SQL Server Configuration Manager.
SQL Server Configuration Manager
2. On SQL Server Configuration Manager, select SQL Server Services on the left window. If the state on SQL Server Browser is not running, you have to configure and start the service. Otherwise, you can skip to step 6.

4. On SQL Server Browser Properties, move to Service tab and change Start Mode to Automatic. Therefore, the service will be start automatically when the computer starts. Click OK to apply changes.
Set Start Mode to Automatic
5. Back to SQL Server Configuration Manager, right-click on SQL Server Bowser on the right window and select Start to start the service.
Start SQL Server Browser Service
6. On the left window, expand SQL Server Network Configuration -> Protocols for SQLEXPRESS. You see that TCP/IP protocol status is disabled.
Protocols for SQL EXPRESS
7. Right-click on TCP/IP and select Enable to enable the protocol.
Enable TCP/IP protocol
8. There is a pop-up shown up that you have to restart the SQL Service to apply changes.
Need to Restart SQL Server Service
9. On the left window, select SQL Server Services. Select SQL Server (SQLEXPRESS) on the right window -> click Restart. The SQL Server service will be restarted.
Restart SQL Server Service
10. Open Microsoft SQL Server Management Studio and connect to the SQL Server 2008 Express.
Open Microsoft SQL Server Management Studio
11. Right-click on the SQL Server Instance and select Properties.
Open Server Properties
12. On Server Properties, select Security on the left window. Then, select SQL Server and Windows Authentication mode.
Change Authentication to SQL Server and Windows Authentication
13. Again, there is a pop-up shown up that you have to restart the SQL Service to apply changes.
