Start Learning Visual Basic

Visual Basic, first programming language I learn. Why do I learn Visual Basic is because of a need. I have to master this programming language, now it is still on progress. My Job orders me to be able programming in Visual Basic. How about you ? I’m sure if you decide to start learning visual basic, it is because you are need or interested in. Ya here we go, start learning Visual Basic. But for beginner, we begin with Visual Basic 6.


INTRODUCTION

Visual Basic is a third-generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming model first released in 1991. Microsoft intended Visual Basic to be relatively easy to learn and use. Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI)applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation ofActiveX controls and objects.

A programmer can create an application using the components provided by the Visual Basic program itself. Over time the community of programmers have developed new third party components, keeping this programming language to modern standards. Programs written in Visual Basic can also use the Windows API, which requires external function declarations. Furthermore, new third party functions (which are open source) using part VB6 source code and part embedded machine code, make the Visual Basic 6.0 applications faster than those designed in C++.

The final release was version 6 in 1998 (now known simply as Visual Basic). Though Visual Basic 6.0 IDE is unsupported as of April 8, 2008, the Visual Basic team is committed to “It Just Works” compatibility for Visual Basic 6.0 applications on Windows Vista,Windows Server 2008 including R2, Windows 7, and Windows 8. In 2014 there are hundreds of thousands of developers who still prefer Visual Basic 6.0 over Visual Basic .NET. Moreover, in recent years both mass media and developers lobbied aggressively for a new version of Visual Basic 6.0.

A dialect of Visual Basic, Visual Basic for Applications (VBA), is used as a macro or scripting language within several Microsoft applications, including Microsoft Office.

My Desktop Shortcut is Broken / Error, How to fix it ?

iconerror

Yesterday, my friend told me that his computer was getting some error, its desktop shortcut changed into another icon symbol. And those shortcut was unable to be executed. I tried to find to fix it, and who knows there was an error in the shortcut registry. If I knew the registry well, I would be able to fix it by myself. But I chose to browse it at the internet and I got a pack of registry to fix them. Don’t be panic, don’t re-install your PC / Laptop, just do this :

  • Open and extract the file you’ve downloaded.

reg1

  • Double klik the registry file.
  • Restart your PC and shortcuts return to be normal.

How Does Antivirus Software Work

How Antivirus Works

Scanning files, identifying and eliminating computer viruses and other malicious software’s are what an antivirus software program does.It is a computer program.

There are mainly two techniques in which the antivirus program accomplishes this process.

1. We need to examine files with the help of virus dictionary in order to look for known viruses so that we can remove them and save all your files and documents from getting deleted.

2. It is also very necessary to identify suspicious behavior from a computer program which can make some kinds of infections.
With an emphasis on the virus dictionary approach, most commercial anti-virus software uses both of these approaches as they are good techniques and can make your computer virus free thereby keeping you tension free..

VIRUS DICTIONARY APPROACH

When the anti-virus software examines a file in the virus dictionary file, it refers to the dictionary of some kind of known viruses that must have been identified by the author of the antivirus software. If a virus identified in the dictionary matches with a piece of code in the file, the antivirus software will either make the file inaccessible to other programs or will completely delete it. It also attempts to repair the file by removing the virus itself from the file and makes the virus unable to spread.

The virus dictionary approach requires periodic online downloads of updated virus dictionary entries in order to be successful in the medium and remain in it for a long term. Infected files or the new antivirus that are found can be sent to the author of the antivirus software who will include all the information of the viruses in their dictionaries.

When the computer’s operating system creates, opens, and closes the files, Dictionary-based anti-virus software typically examines. Accordingly a known virus can be detected immediately upon receipt. The software also schedules itself to examine the file on a regular basis.

In order to not match the virus signatures in the dictionary, the authors modify themselves as a method of disguise. Virus authors have tried to stay a step ahead of such polymorphic viruses even though the dictionary approach is considered effective.

Fluorescent Lamps (TL) Circuit

Diagram Block of TL Lamps
Fluorescent lamps is more commonly known as TL lamps. This type of lighting is more widely used because of the power used is relatively small compared to the light bulb. Besides fluorescent lamp also colder than light bulb with the same power usage.
The use of fluorescent lighting is very broad and very good in general for home lighting or lighting on industries. The advantage of the fluorescent lamp, as mentioned above is to produce light output every watt of power used is higher than ordinary light bulb (incandescent lamp).
