Using Delphi to quickly create applications
Mar 28th
This following article is a guest post by Sam Tyler
There are lots and lots of quick application builder programs that emerge constantly. Its hard to keep up with them all. You may have the need to create some great applications and then quickly package and turn them into a product that can be sold on a marketplace. In this regard, one software package that always hits the home run for me is Delphi. It first came out as the rapid application builder, then many early adopters were able to quickly see their returns investing on it. Creating a simple hello world is cheerful process that you can do it even on your first day programming delphi. Delphi to me is the visual pascal, or technically its the object pascal. Though a simple hello world application is around 300 kb, complex applications are much more less than what it would consume on other programming platforms.
So whenever i need a widget to promote and market my website, i resort to delphi, which is my fastest way of churning out applications. You may worry about the lack of extensions, never be. Delphi extensions or components by which they are called, are available in large. Those come with a package bundled together referred to as Visual component library. Now, you may have heard of VCL before in Visual C++, this is similar to that. If you can name a component you can get it online, for free or for a little price. One such freely available component is from a team, JEDI project. JEDI's Windows API library makes WinAPI much more accessible. Be it you need to fetch the multiple cpu's processing power or getting a bios version, its possible with a function, nothing could be better than this.
If you feel to try it out before you pay for it, get turbo delphi, which is free and let you see what delphi can really do for you. Like many programming packages, delphi progresses through versions. The one i have is Delphi 7, and still use it to date. Once you test drive with turbo delphi, you can confidently invest in the latest Delphi, which is Delphi 2010. After you have decided that delphi is for you, there are great places to learn this language completely. Places like delphi.about.com is all the meat and potatoes for learning the art of delphi with examples and free source code projects. Its when my learning curve picked up real quick and i became really better at this. Now after a month programming on delphi, im really excited to share my knowledge with you. Be it for creating a rapid application or just playing with it creating toys to expand my creative horizons i go to delphi. Oh i almost forgot, if you want to see the first application i created with delphi, just google, smartsys monitor and happy programming in delphi!

Note that this is for Windows only!
Some people have been experiencing this problem lately: You plugin in your iPhone, the Camera detected window pops up, iTunes may even open, but the iPhone doesn't sync or even show in the sidebar!
Here is how to fix it:
- With the iPhone plugged it, close iTunes
- Go to your Control Panel
- Open up Administrative Tools (This name may vary depending on your language. The icon shows a folder, a computer and a hummer)
- Open up Services
- Locate the service "Apple Mobile Device"
Now open up iTunes, and your iPhone should show up! I have tested this on Windows XP only, if it works for you on other versions please let me know to update the post
Understanding Computer Error Codes And How To Resolve Them
Jan 27th
The error codes that accompany various computer errors are not just random numbers. They denote something and are your first step toward identifying the cause of the error. For example, based on the error code, you may determine whether an error is a software error or a hardware error.
To successfully resolve error codes, you first need to ascertain the cause of the error. Understanding the cause of an error code immensely helps in troubleshooting the error.
In this article, we will discuss common causes of computer error codes and steps you can perform to resolve them.
Malware Infection
Malware infection is the root cause of many computer errors, such as error 0x80040702. Malware programs, such as viruses, rootkits, and trojans are known to modify or delete important files. As a result, an error occurs every time a program tries to access the infected file.
To resolve errors occurring due to malware infections, perform a malware scan of your entire computer using reliable and advanced antivirus tool and antispyware tool.
Incorrect installation/uninstallation of programs
Incorrect or incomplete installation of programs or software also causes various errors. To resolve errors that are a result of incorrect installation, uninstall the program and reinstall it. When installing the program, ensure that the installation setup files are healthy and undamaged. Furthermore, if you are installing the new program using an installation disc, make sure that the installation CD or DVD is unscratched.
Furthermore, do not install programs that are incompatible with your operating system. Conflicting software may alter or replace important Windows files and cause errors, such as the stop error c000021a. To resolve such errors, remove the software that is causing the error.
Incomplete unisntallation of programs also leads to various errors. The leftover files or processes of the removed program may interfere with other running processes and cause errors. To ensure complete removal of programs, you may use an advanced and reliable third-party uninstaller tool.
Outdated Windows, software and driver files
You may also receive various errors if your Windows or driver files are outdated. This is why it is imperative that you regularly install new updates pertaining to your operating system and drivers.
To automatically install new Windows updates, enable the Automatic Update feature that is available in Windows XP and later versions of Windows computers. To ensure that your drivers are regularly updated, you may use a reliable and easy to use third-party driver scanner tool. Such tools automatically install new drivers, as and when they are released by their manufacturers.
Furthermore, also ensure that all your third-party software programs are also regularly updated. Outdated software may slow down your computer or cause errors due to compatibility issues with other computer components or programs.
Corrupt or damaged registry
A corrupt or damaged registry may cause innumerable errors, such as error 2739. To fix your damaged registry and errors caused by it, schedule regular registry scans using efficient registry cleaning software.
Faulty hardware
You may also receive various errors if your hardware components, such as memory modules or hard disk, are damaged or corrupt. To resolve hardware related errors, first identify the hardware component that is causing the error and then get it replaced or repaired.
PC Application Errors and How To Deal With Them
Aug 1st
Your Windows operating system comes packaged with some useful applications such as a word processor, a spreadsheet, a calculator and so on. However, with the passage of time, you end up installing several other applications to meet your specific requirements. If you have a branded PC, there are a number of other applications which come pre-installed, besides your Windows operating system.
Almost all applications on your PC add and use DLL files or Dynamic Link Library Files to perform specific tasks. These DLL files were originally created by Microsoft to improve the efficiency of Windows operating system. Later, a number of other applications started using the same DLL files. Furthermore, many application manufacturers began developing their own DLL files.
Causes of DLL Application Errors
Whether they are core operating system DLL files or DLLs belonging to a certain application, most of the DLL files are stored in the Windows directory. This enables easy access to all applications installed on your computer. With so many DLL files being used simultaneously by a number of applications, it’s quite natural for you to encounter application related DLL errors at one time or other.
A malware infection, a corrupt hard drive, a damaged Windows registry, an accidental deletion of a critical DLL file or overwriting a newer DLL version with an older one are some of the reasons which may generate DLL error messages.
For example, “clb.dll application has failed to start error" and “xprt5.dll application error” may occur if the given DLL file is either corrupt or missing. Here, Clb.dll is one of the Windows operating system’s core files. The xprt5.dll is a part of the XPRT Runtime Library program. This file usually gets installed with AOL instant messenger.
How to Deal With DLL Application Errors
Dealing with DLL errors is not very tough, as long as you take a systematic approach to fix the error. Here are general steps that you may follow to fix these errors:
- If the file gets deleted by mistake, check the Recycle Bin to see if it is there. In case you find the missing DLL file, restore it to resolve the error. You may also use a file recovery software to do the task. Avoid downloading the missing DLL from an online DLL web site. Many such DLLs are known to be malware in disguise. You may end up causing more harm to your PC by using these downloaded DLL files.
- If a system DLL file is missing, replace it by extracting the original file from the Windows setup CD.
- Install the latest version of the software to which the DLL file belongs.
- Update your Windows operating system. You can do this by using the Windows Update tool that comes with Windows.
- Scan and clean your PC from any infections from virus, worms, Trojans, or spyware. Use reliable and efficient antivirus and antispyware tools for this task.
- Scan your registry for invalid and incorrect DLL entries. Registry problems are known to be one of the common causes of several DLL errors. An easy and efficient method to fix registry DLL errors is by using a compatible and genuine registry repair tool.
Deal with registry errors and avoid its inconvenient effects
Feb 16th
For those who are just starting to learn about the many components of the computer's operating system, it's very important to start in familiarizing with the registry. This is because all information that is related to the hardware and software configuration of the computer; the system and network systems as well as user profiles are accessed, modified and stored in it. Every time a change is made to the system, the registry takes note of it all.
Errors are generally caused by the presence of obsolete and outdated entries in the registry. This are entries that are left deleted automatically the moment they are not already useful. After a long time they can accumulate which leads to the production of holes or empty spaces in the registry. Aside from that, these leads to the registry's corruption, damage as well as its fragmentation. If not properly dealt with, it can cause various problems especially in the overall performance of the computer system.
Another common cause of registry errors is the presence of malwares such as viruses, worms, adwares, spywares and Trojans. They add a lot of unwanted data and information, which is often permanent or very difficult to remove at all, within the registry. Not only does it affect the registry, it also damages files and programs as well. This can lead to the freezing of the computer system and even damage to the hardware itself.
In order to get rid of registry errors for good, registry cleaner software is mostly used. It enables you to search and fix any registry error that is present. It searches for obsolete entries, registry holes and fragments in the whole registry. Aside from that, it can also weed out any undesirable keys or data that are brought about by the presence of any type of malware. An efficient registry cleaner can also help in making regular registry backups in case the registry needs to be restored to a certain point in the past. Lastly, a good registry cleaner software can help in ensuring a faster data access as well as defragment the registry.
A proper registry cleaner is widely available from many computer shops both actual and online. However, it doesn't mean that you will just buy any kind of registry cleaner. Excellent user reviews can help a lot in choosing the best kind of registry cleaner. This is because knowing the opinion of other people can already help you know a specific software's advantages and flaws even without trying it personally. Aside from that, it is also important to remember that the version of your operating system is also detrimental to the king of registry cleaner. Also, it must be suited to your specific needs and requirements.
Having a healthy registry can help in avoiding the many inconveniences that can come as a result of registry errors. Why experience the slowing down of your pc, the failure of many program startups as well as the ultimate crashing down of your system if you can take the proper steps in preventing or getting rid of its causes.
