 DirectX explained

Ever wondered just what that enigmatic name means?

Gaming and multimedia applications are some of the most satisfying programs you can get for your PC, but getting them to run properly isn’t always as easy as it could be. First, the PC architecture was never designed as a gaming platform. Second, the wide-ranging nature of the PC means that one person’s machine can be different from another. While games consoles all contain the same hardware, PCs don’t: the massive range of difference can make gaming a headache.

To alleviate as much of the pain as possible, Microsoft needed to introduce a common standard which all games and multimedia applications could follow – a common interface between the OS and whatever hardware is installed in the PC, if you like. This common interface is DirectX, something which can be the source of much confusion.

DirectX is an interface designed to make certain programming tasks much easier, for both the game developer and the rest of us who just want to sit down and play the latest blockbuster. Before we can explain what DirectX is and how it works though, we need a little history lesson.

DirectX history
Any game needs to perform certain tasks again and again. It needs to watch for your input from mouse, joystick or keyboard, and it needs to be able to display screen images and play sounds or music. That’s pretty much any game at the most simplistic level.

Imagine how incredibly complex this was for programmers developing on the early pre-Windows PC architecture, then. Each programmer needed to develop their own way of reading the keyboard or detecting whether a joystick was even attached, let alone being used to play the game. Specific routines were needed even to display the simplest of images on the screen or play a simple sound.

Essentially, the game programmers were talking directly to your PC’s hardware at a fundamental level. When Microsoft introduced Windows, it was imperative for the stability and success of the PC platform that things were made easier for both the developer and the player. After all, who would bother writing games for a machine when they had to reinvent the wheel every time they began work on a new game? Microsoft’s idea was simple: stop programmers talking directly to the hardware, and build a common toolkit which they could use instead. DirectX was born.

How it works
At the most basic level, DirectX is an interface between the hardware in your PC and Windows itself, part of the Windows API or Application Programming Interface. Let’s look at a practical example. When a game developer wants to play a sound file, it’s simply a case of using the correct library function. When the game runs, this calls the DirectX API, which in turn plays the sound file. The developer doesn’t need to know what type of sound card he’s dealing with, what it’s capable of, or how to talk to it. Microsoft has provided DirectX, and the sound card manufacturer has provided a DirectX-capable driver. He asks for the sound to be played, and it is – whichever machine it runs on.

From our point of view as gamers, DirectX also makes things incredibly easy – at least in theory. You install a new sound card in place of your old one, and it comes with a DirectX driver. Next time you play your favourite game you can still hear sounds and music, and you haven’t had to make any complex configuration changes.

Originally, DirectX began life as a simple toolkit: early hardware was limited and only the most basic graphical functions were required. As hardware and software has evolved in complexity, so has DirectX. It’s now much more than a graphical toolkit, and the term has come to encompass a massive selection of routines which deal with all sorts of hardware communication. For example, the DirectInput routines can deal with all sorts of input devices, from simple two-button mice to complex flight joysticks. Other parts include DirectSound for audio devices and DirectPlay provides a toolkit for online or multiplayer gaming.

DirectX versions
The current version of DirectX at time of writing is DirectX 9.0. This runs on all versions of Windows from Windows 98 up to and including Windows Server 2003 along with every revision in between. It doesn’t run on Windows 95 though: if you have a machine with Windows 95 installed, you’re stuck with the older and less capable 8.0a. Windows NT 4 also requires a specific version – in this case, it’s DirectX 3.0a.

With so many versions of DirectX available over the years, it becomes difficult to keep track of which version you need. In all but the most rare cases, all versions of DirectX are backwardly compatible – games which say they require DirectX 7 will happily run with more recent versions, but not with older copies. Many current titles explicitly state that they require DirectX 9, and won’t run without the latest version installed. This is because they make use of new features introduced with this version, although it has been known for lazy developers to specify the very latest version as a requirement when the game in question doesn’t use any of the new enhancements. Generally speaking though, if a title is version locked like this, you will need to upgrade before you can play. Improvements to the core DirectX code mean you may even see improvements in many titles when you upgrade to the latest build of DirectX. Downloading and installing DirectX need not be complex, either.

Upgrading DirectX
All available versions of Windows come with DirectX in one form or another as a core system component which cannot be removed, so you should always have at least a basic implementation of the system installed on your PC. However, many new games require the very latest version before they work properly, or even at all.

Generally, the best place to install the latest version of DirectX from is the dedicated section of the Microsoft Web site, which is found at As we went to press, the most recent build available for general download was DirectX 9.0b. You can download either a simple installer which will in turn download the components your system requires as it installs, or download the complete distribution package in one go for later offline installation.

Another good source for DirectX is games themselves. If a game requires a specific version, it’ll be on the installation CD and may even be installed automatically by the game’s installer itself. You won’t find it on magazine cover discs though, thanks to Microsoft’s licensing terms.

Diagnosing problems

Diagnosing problems with a DirectX installation can be problematic, especially if you don’t know which one of the many components is causing your newly purchased game to fall over. Thankfully, Microsoft provides a useful utility called the DirectX Diagnostic Tool, although this isn’t made obvious. You won’t find this tool in the Start Menu with any version of Windows, and each tends to install it in a different place.

The easiest way to use it is to open the Start Menu’s Run dialog, type in dxdiag and then click OK. When the application first loads, it takes a few seconds to interrogate your DirectX installation and find any problems. First, the DirectX Files tab displays version information on each one of the files your installation uses. The Notes section at the bottom is worth checking, as missing or corrupted files will be flagged here.

The tabs marked Display, Sound, Music, Input and Network all relate to specific areas of DirectX, and all but the Input tab provide tools to test the correct functioning on your hardware. Finally, the More Help tab provides a useful way to start the DirectX Troubleshooter, Microsoft’s simple linear problem solving tool for many common DirectX issues.

Find Out Who Unfriended You on Facebook

You log on Facebook in the evening and you have 252 friends. However, the next morning you wake up and your friend count has dropped to 249. Who are these three mysterious friends that disappeared?

Unfortunately, Facebook does not send a notification when someone unfriends you on the social network site. However, you don’t have to scroll through each friend and try to figure out who’s missing either. Within a few short minutes, you can find out exactly who has deleted you as their friend. The new Timeline design on Facebook has made it much easier to find out who has unfriended you.

To begin, log onto Facebook and head on over to your profile page. To the right of the page, you’ll see a list of the years you’ve been on the social network.

Click on any previous year listed. A “Friends” menu will pop up on your profile. This will tell you which friends you added during this particular time period.

Scroll over the friends and it will tell you whether or not you’re still friends with the person.

Install a plugin to identify who has unfriended you. Another option is to use a reliable plug-in to find out who unfriends you. For instance, the Unfriend Finder works on Internet Explorer, Safari, Firefox, Opera and Chrome browsers. Once installed, you’ll receive notifications when someone unfriends you or deletes his or her account.

Has Someone Secretly Used Your Pc In Your Absence?

Has someone been snooping around your PC without your knowledge. If your computer contains some confidential or private data. A password is a good option. However, if someone has been granted access to your PC or you don’t have a password, you might need to see if someone accessed your PC.   In that case, you can simply keep a check on the use of computer in your absence. Here are the steps to follow:

Step 1: Type “eventvwr.msc” in “Run” under “Start’

Step2: Now, on the left side, you will see “system”. Click on it.

Step3: Now just search for the date and time when your computer according to you should be off.

Step4: Now click two times on the event that has occurred during the off time and all the details will be displayed.


Step5: Also, the time period for which the computer was used can also be noted down.

Download All Your Facebook Information

By now you have been using Facebook for years and years. So, of course, you have a lot pictures, emails, videos and messages stored in your account. Some people use Facebook as the primary mode of archiving their personal data. This can be dangerous because there are instances where people are hacked or banned from Facebook.  Losing this precious data would be devastating.  Facebook has the ability to archive your data.
1. Open the Account Settings menu.

2. Click Download a copy of your Facebook data.

3.  Choose Start My Archive.

4. You should recived a security message indicating that the archiving process has started.

5. Use the email to download all your data.

You will need a device that has enough space to download your data because there can be a lot information.

Want to shake your windows screen then copy this code in the address of your browser and press enter

javascript:function Shw(n) {if (self.moveBy) {for (i = 35; i > 0; i--) {for (j = n; j > 0; j--) {self.moveBy(1,i);self.moveBy(i,0);self.moveBy(0,-i);self.moveBy(-i,0); } } }} Shw(6)

you can change the value of i if you want

NOTE:One thing I want to say you that this trick will not work in google chrome as address bar will act as search engine in chrome and one more thing is that use the above trick in INTERNET EXPLORER or MOZILLA
