Change The Default Location For Installing Application

2010-01-30T05:28:00.000-08:00

As the size of hardrives increase, more people are using partitions to seperate and store groups of files.

XP uses the C:\Program Files directory as the default base directory into which new programs are installed. However, you can change the default installation drive and/ or directory by using a Registry hack.

Run the Registry Editor (regedit)and go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

Look for the value named ProgramFilesDir. by default,this value will be C:\Program Files. Edit the value to any valid drive or folder and XP will use that new location as the default installation directory for new programs.

How to customise your start button

2010-01-30T05:24:00.000-08:00

First you need a tool called "Resource Hacker". This free program allows you to change resources in any .exe file such as "Explorer.exe", which includes the [Start] button's Label. You can visit Download.com and search there for "Resource Hacker".
After you download it, follow the guide here:

Step 1:

A - Run "Resource Hacker" and open the file "%windir%\Explorer.exe".
B - You see a Tree of all Resources in this file, expand the "String Table"
C - Find the "start" and replace it with your own text. then press the [Compile Script] button.
D - Save "Explorer.exe" as "MyStart.exe" DONT save it as Explorer.exe, do "save as.." and give it a new name.
E - Quit "Resource Hacker".

Step 2:

A - Click on the [Start] button and choose the "Run..." item from the start menu. (Or use the shortcut key WinKey+R)
B - Type "RegEdit" in the Run "Dialog Box". And then press the [Ok] buton to run the "Registry Editor" program.
C - Go to: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon" and find the "Shell" property.
D - Replace value of the "Shell" property to "MyStart.exe".
E - Quit "Registry Editor".
F - Restart your system.

Note about Registry Editor:
if you did not find the key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon", you can search the Registry for the "Explorer.exe", to do this use the Edit Menu | Find Next (Ctrl+F).

10 reasons why computers crash you must Know

2010-01-30T05:07:00.000-08:00

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

4 Hard disk drives

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5 Fatal OE exceptions and VXD errors

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6 Viruses

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

7 Printers

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.

8 Software

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9 Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.

10 Power supply problems

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

Computer programming is at the core of any computer operation. Unlike usual electro mechanical devices, a computer requires software to carry out instructions. At the lowest level, machine code is used to control the hardware and operations of a computer. The machine language is a set of zeros and ones and rather tedious to handle. Therefore the instructions are coded in a higher level language called a computer program. The conversion of a higher level language into a machine code is carried out by assembly level languages or assemblers. The transformation is completed without any human interface.

During the initial days when computer programs were still at a nascent stage of development, languages such as COBOL and BASIC were highly popular. As the computing power of computers increased ,the demand for more efficient programs emerged. The third generation programs had better portability and efficiency compared to the earlier generations. The need to handle enormous amount of data gave rise to specialized software called database management software or more specifically relational database management software. Companies like Oracle, IBM and Microsoft have developed their own version of RDBMS. On the processing front ,Mainframes were using COLOL for business applications and FORTRAN ( Formula Translation ) for scientific applications.

The concept of modularity became popular when hundreds of software programmers worked simultaneously on a single large project. Object oriented programs like C++ gathered popularity. The code used in these higher level languages was reusable and the techniques could provide for better efficiency.

Microsoft meanwhile brought out its own operating system which could be used on personal computers. In a matter of years the Windows OS became a unprecedented success. The OS2 operating system used by Apple computers was relegated to a second position. IBM has been providing other system software but none could reach the popularity levels of Windows. The only problem with Windows is the issue of security breaches. Though Microsoft has been striving hard to plug the security holes, it has not been entirely successful.

Modern computer programs strive more and more to behave like human language. Technologists believe that a day would come when one could program a computer by given verbal instructions. Surely that's not going to happen in a hurry. Artificial intelligence, expert systems, fuzzy logic and many more state of the art technologies are changing the face of programming.

Computers unlike any other machine require a software program to operate. It speaks in machine language which is gibberish to the human mind. Higher level languages are used to translate recognizable instructions into machine language. As we progress, the higher level languages would resemble human languages.

At the beginning of the computer era, a single program used to execute different functions. Today, specialized programs are tailor made for different applications. Complex programs require many programmers to work simultaneously on a single project. Modular languages are well suited for such large projects. Object oriented programming has become popular due to their modularity and ease of use.

Author: Suparna

Websites play a significant role in managing an online business and a well-made website can provide you with key to success in the virtual world. To build a perfect websites web programmers play a crucial role. Many people are quite unaware of the fact what web programming entails. The term ‘web programming’ encompasses a series of procedures including planning, conceptualization, modeling of electronic media delivery with the help of internet and through Markup language or software language which are suitable for interpretation by the Web browser as wells as the GUI or the Graphic User Interface.

The purview of web programming is actually quite wide. Web site programming services encompasses a wide array of websites like database driven websites with their huge data banks and archives. Special web programming is also needed for e-shops or e-commerce websites with their own shopping carts and online payment procedure. It is the web programmers who create dynamic as well as static flash websites with loads of animation and interactivity.

Thus, the jurisdiction of web programming is quite huge and it stretches from professional websites owned by business conglomerates, e-commerce websites selling products to informative websites like online libraries and encyclopedias. Even interactive online gaming websites are also the handiwork of adroit web programmers. Once the websites are launched the website maintenance and technical glitches faced by the websites are also handled by the web programmers.

Since web programming involves quite an intricate series of procedures that is why web programmers require technological dexterity and high level of know-how in software languages. Web programmers need to be highly skilled and flexibility so that they can employ their technical know-how as per the needs of the website owner. The proficient web programmers are well acquainted with an array of cutting edge web technology and software languages such as, Windows NT, Java, Servlets, MySQL, MSSQL, Oracle and MSAccess, JavaScript, WAP Applets, EJB, Perl. Not only creating the website with these software programming web programs can also enhance the visual appeal of these websites by working on graphics related software tools such as Photoshop, Corel Draw, Animation S/W, Flash Dreamweaver, Frontpage etc.

Efficient web programmers not merely create the web programs for a website but they also make effective control panels so that the website owners can log into that allows the website owners to and administer the content, application and other aspects of the website. That is why it is crucial that the web programmers decide on the application tools for a website after a detailed interaction with the client.

Whatever may be the size of the project, whether it is a huge e-commerce portal or a small personal blog site, it is the duty of the web programmer to settle on the software programs with a proper discussion with the client so as to ensure 100% satisfaction of the client. If it is an old existing website then new programs should be designed by the web programmers in a way that they are seamlessly integrated with the existing programs. Thus, there are various nuances of web programming.

Now days an array of web programming service providers are available in the market who can provide you with top-notch website programming service at a competitive rate. Since in the cut-throat world of online business reducing overhead costs and expenditure matters a lot that’s why many web programmers are providing excellent service to business owners at an affordable price. India has become a virtual hot bed for web programming since Indian web programming service providers can provide superior service in budget rates.

Direct Success With A Computer Programming Degree

2009-12-22T06:12:00.000-08:00

Author: Andy West

A computer programming degree is one of the most sought after degrees in the field of information technology. While it is often mistaken as one of the easier areas of IT, the truth of the matter is: those who do not have an aptitude for detail or the ability to think in an abstract manner may not find it as easy as they assume it is. A computer programmer is one who, like other hands on vocations, must work with extreme precision and craftsmanship.

At the same time, many people choose computer programming because it is not a deep or multi faceted subject as that of chemistry, physics or other material sciences. While computer science has its own theories, it is not the center of the world for computer programming. Many enjoy computer programming for its physical, hands on approach.

One of the things that can make earning a computer programming degree much easier is a natural tendency for paying attention to detail. Unknown to many, computers are simple machines that will only do as they are instructed. A programmer whose job is to set forth directives knows that leaving out even the smallest part of information can cause major problems.

Another helpful skill to have is that of a good memory. The number of variables that go into a computer program concerning syntax, functions, bugs, solutions and much more can be quite staggering. However, the more information and data one can remember on their own, the more successful their career will be.

Some would say the most crucial skill for this line of work is being able to keep a number of complex working systems in mind all at once. While this will take some time and skill to master, it is one of the great traits of a computer programmer. This ability to think abstractly can help with programs exhibiting up to 1,000,000 or more lines of code.

Typically, a Bachelor's degree is required for many entry-level positions in this field. Those who graduate with a Bachelor's degree will have training in analytics and the implementation of computer systems as well as maintenance and even design. With this type of computer programming degree one may find themselves with career opportunities in software programming, network programming or website programming.

A master's degree in computer programming allows graduates to implement high-level software programs. Because of the ever-changing world of technology, they often design software for business environments that greatly rely on technology as well. While being trained in a number of different programs, those with Master's degrees also put their leadership skills into use as the head or director of IT departments.

Whether opting for a Bachelor's or Master's, many in this field find they have the benefit of one of the highest earning powers of any industry available. With such a heavy dependence on computers and technology, the demand for such professionals is in just about every area on the map. There is no doubt that this is a strong profession with a solid future.

This type of degree means always getting to be at the forefront of the latest changes. Programmers must also earn certifications in certain programs and update them regularly to keep up with the newest technologies. Many in this field enjoy the opportunity to continue learning and the ongoing training needed in this fast paced world.

A computer programming degree encompasses so much that many in this field find their career constantly evolving right along with technology. There are so many different areas in which to branch out and grow, there is no worry of ever becoming bored or getting stuck in a rut. Programmers have the fulfillment that comes with seeing their work have a positive effect.

What is jtag and how about arm jtag

2009-12-14T19:29:00.000-08:00

Author: jitkasem

This story is about JTAG for arm microcontroller.

Jtag is an important equipment use for programming (flash) and debugging
various microcontroller series.This story is about jtag for arm microcontroller.
Nowadays normally used jtag is divided in to two interfaces. One is parallel and the
other one is USB.These two kinds of jtag have and advantage and dis-advantage that is
the USB-jtag is faster and it can connect to almost PC of today but of course it is
more expensive than parallel jtag.Parallel-jtag is an old format jtag but it can still
be used upon now with the PC that have a parallel port.

Arm jtag is also can be divided in to two group (USB and parallel).On the
market Arm jtag has a various name that is J-link , U-link , R-link.Thease kinds of
jtag is categorized depend upon the IDE that use for debugging and programming
your current arm microcontroller.As an example , suppose that you use IAR Embedded
Workbench for debugging you LPC2378 development board , in this case you much use
the J-link that is supported by IAR Embedded Workbench.The X-link that I mentioned
above is jtag that is not open-source and was invented by the microcontroller software
tools company. Arm jtag has an open source too. It is call OpenOCD.OpenOCD is one kind
of jtag that can be used to flash and debugging arm microcontroller with the free
software development tool such as Eclipse.OpenOCD also have USB or paraller interface.
To setup the IDE used for OpenOCD must integrate many tools together. Such as Eclipse as
the main IDE, arm-gcc compiler ,arm-gcc linker and the gdb server. To read more about
OpenOCD please visit –>

http://openocd.berlios.de/web/

http://www.yagarto.de/

To select which Arm jtag that is suitable for you is based on the software IDE and
software programming and debugging tools you use to develop that arm project.But the normally Arm jtag
selection is as follow

IAR Embedded Workbench for ARM -> use J-link.
Keil MDK-ARM , Keil uVision for ARM (ARM RealView) -> use U-link.
Ride7 IDE from raisonance -> use R-link (Normally used for STMicroelectronics microcontroller series) .
Open source IDE -> use OpenOCD jtag.

ASP NET programming for beginners

ASP NET programming for beginners

Author: Vikas S

ASP net programming is a web application developed by Microsoft. It is a powerful web application that allows programmers to build dynamic websites, web services and web applications.

There are two important things to note about ASP. It is not a programming language, but a technology that allows a web application development . The action involved in this technology takes place on the server and not the personal computer. When on a server, it can interpret different programming languages including JavaScript, PerlScript and VBScript. It is also possible to mix these languages on the same ASP web page framework in order to obtain better results.

In order to get started with it, you need a web server and a .NET framework. Make sure the web server supports the .NET framework. It can wither be Microsoft IIS (Internet Information Services) or an Apache 2 with mod_aspdotnet in it. Once the web server has bee set up, you need to consider the text editor you would use. Notepad on Windows or Emacs on Linux are good editor choices.
