That means less programming is required when adding functions to complex systems. If a step is added at the bottom of a hierarchy, then only the processing and data associated with that unique step needs to be added.
Everything else about that step is inherited.
The ability to reuse existing objects is considered a major advantage of object technology. Polymorphism Object-oriented programming allows procedures about objects to be created whose exact type is not known until runtime. For example, a screen cursor may change its shape from an arrow to a line depending on the program mode.
The routine to move the cursor on screen in response to mouse movement would be written for cursor, and polymorphism allows that cursor to take on whatever shape is required at runtime. It also allows new shapes to be easily integrated.
VB6 is not a full OOP in the sense that it does not have inheritance capabilities although it can make use of some benefits of inheritance. It is different from the earlier versions of VB because it focuses more on the data itself while the previous versions focus more on the actions.
Previous versions of VB are known as procedural or functional programming language. Some other procedural programming languages are C, Pascal and Fortran. VB allows users to write programs that break down into modules.
These modules will represent the real-world objects and are knows as classes or types. An object can be created out of a class and it is known as an instance of the class. Begin by starting Visual Studio from the Windows Start menu.
Visual Studio will display the "New Project" dialog shown below:. The New Project dialog provides a number of options with regard to the type of project being created.
In this example we are going to build a Windows Application. A Windows Application is a graphical application in other words an application that appears in a window and contains buttons, text fields and all the other graphical items we expect to see when we run Microsoft Windows applications.
Select the Windows Application icon from the New Project dialog and give your new project a name by typing it into the Name: Click on the OK button to create the project.
Once the project is created Visual Studio will display the new project, which at this point consists of a single form, ready for us to start adding visual components:. Now that we have created a new project in Visual Studio it is time to move on to the next chapter and create a simple Visual Basic application.
