When software developers started to write a lot of programs, they started to realize that the programmer’s job is not finished when he has written the code. There are many things that can go wrong in the future and the programmer will have to be able to detect them. This is where error checking comes into play. It’s basically an automated tool designed to do that for you.
The basic idea behind error checking is that all the programs on your computer should be able to do their job by checking whether a particular command sent to them by the user is valid or not. If it’s not valid, they will give you a message telling you that the command was invalid and you have to restart the program.
As you would expect, it’s a very useful feature for anyone who uses a computer every day. The programs that use error checking are mostly the ones that you run on a daily basis such as your email programs and your web browser.
You might be thinking that the use of error checking on your computer is only useful if you have problems with your program’s functionality. The truth is that even if your computer works perfectly, there could be a good reason why your program is not functioning the way it should. For instance, if you install a new program into your computer, you might forget to uninstall the old program from your computer. Now, you have two programs running simultaneously, each trying to do its own thing – one of them might be missing some files and the other might be having some problems.
This is something that can be very problematic if the old program is a good program. If you want to make sure that everything is working as expected, error checking is what you need.
Errors in error checking are usually caused when you do something to your computer that it can’t handle. For instance, when you install new software on your computer, you might also install a program that doesn’t support Windows XP. If you try to start this new software, it will fail to start because it has an older version of Windows installed on your computer. When you try to uninstall this program, Windows will not be able to delete it properly because it has a newer version of Windows installed on your computer.
After the program gets deleted, the registry will still contain traces of it in the registry. As a result, the registry database is not in good condition and you might find that your software is not able to run properly again. Error checking is therefore one important aspect of the Windows operating system, which can cause your software to fail.
If you use a program which is designed to run on Windows XP, you will be surprised to know that a lot of these programs have an option called an uninstall option. If you try to uninstall a program but you don’t have the right software, you might get stuck without having a program to uninstall. Error checking is then a feature which is required to make sure that the program has been properly uninstalled before you can uninstall it.
Error checking is also useful if you’re trying to keep track of changes to your computer or its files. You might make a mistake when you save your data or install a program, and this mistake might cause problems with your computer if it is not fixed immediately.
Users who use Vista have an option in their computer called the Vista Safe Mode to allow you to run any software as an administrator without being logged on to the computer. If the software has an uninstall option, you can run the uninstaller by clicking on the “run” button.
With error checking, you’ll get an automatic message when something goes wrong with your program or with the program’s installation. It will also inform you if the program has been successfully uninstalled. If you don’t have error checking installed in your computer, you may end up installing programs that will cause a lot of problems.
