What is Visual Basic?

    Visual Basic is a computer programming system developed and owned by Microsoft. It was originally created to make it easier to write programs for the Windows computer operating system. The basis of Visual Basic is an earlier programming language called BASIC that was invented by Dartmouth College professors John Kemeny and Thomas Kurtz.

Alan Cooper - "Father of Visual Basic"

   Visual Basic, often referred to using just the initials VB, is designed to make software development easy and efficient, while still being powerful enough to create advanced programs. For example, the Visual Basic language is designed to be "human readable," which means the source code can be understood without requiring lots of comments. The Visual Basic program also includes features like "IntelliSense" and "Code Snippets," which automatically generate code for visual objects added by the programmer. Another feature, called "AutoCorrect," can debug the code while the program is running.

  Visual Basic is easily the most widely used computer programming system in the history of software.

Is Visual Basic just a programming language or is it more than that?

   It's more. Visual Basic was one of the first systems that made it practical to write programs for the Windows operating system. This was possible because VB included software tools to automatically create the detailed programming required by Windows. These software tools not only create Windows programs, they also take full advantage of the graphical way that Windows works by letting programmers "draw" their systems with a mouse on the computer. This is why it's called "Visual" Basic.

   Visual Basic also provides a unique and complete software architecture. "Architecture" is the way computer programs, such as Windows and VB programs, work together. One of the major reasons why Visual Basic has been so successful is that it includes everything that is necessary to write programs for Windows.

The advantages of using Visual Basic:

• Visual Basic applications are event-driven which means that the user is in control of the application.
• Visual Basic supports the principles of object-oriented design which means that the user can compartmentalize different aspects of the application as objects and develop and test those objects independently.
• Visual Basic is a complete Windows application development system which means that it will look and behave like other Windows programs.
• Visual Basic is extensible.

Sample "eOwXzZ pfUeOhWxZz!" (Hello World!) program.

To create the Hello World application, follow these steps:

• Click File then click New Project. You might be asked to save changes to the current project if you’ve been experimenting. If so, click the No button. If you want to keep your work, click Yes.
• If it is not already visible, open Form Layout window by selecting View the Form Layout Window.
• Right-click the form in the Form Layout window. Select Startup Position then Center Screen from the pop-up menu.

eOwXzZ pfUeOhWxZz! (alternate way)

• First, double-click the Display eOwXzZ button then enter the following:

Private Sub cmdEOWXZZ_Click()
    ' Execute a simple message box that will say "eOwXzZ pfUeOhWxZz!"    txtDisplay.Text = "eOwXzZ pfUeOhWxZz!"End Sub

Private Sub Form_Load()
    ' Execute a simple message box that will say "eOwXzZ pfUeOhWxZz!"    MsgBox "eOwXzZ pfUeOhWxZz!"End Sub

Presumptions and sentiments

• Opinions of ICS instructors

"Visual Basic? IT SUCKS!"

- Professor Reginald Recario (aka Friend ni Agnes)

"Visual Basic is an object-based programming language, not object-oriented where most literature consider it as such. It's very easy to learn and program using Visual Basic. Actually ayan yung ginamit namin nung highschool. Meron din niyan sa ENSC, yung elective."

- Professor Maan Clariño

• Opinions, by yours truly (Carly Rae Jepsen)

"Visual Basic is one of the most common programming languages one can easily master and utilize at his disposal. It provides a great experience for its users to have a feel of how programming works firsthand. Visual Basic's pièce de résistance is its graphical user interface where users are able to perform tasks with ease. This includes the drag-and-drop features for the user interface." - Ralph Dela Rosa

"Visual Basic? I think it's basic, of course. You can learn it easily." - Roma Rojas

"Visual Basic for me, is BASIC. You can easily make a simple program by using it. I think, programming it is easy to implement because it also has its own interface and you don't need to program it because all you need to do is drag and drop." - Grace Dellosa

"Because of it's point and click system, I think Visual Basic is the easiest to learn of all the programming languages that offers Graphical User Interface. " - Carlo Pinili
