Visual Basic NET Is Used for Writing Windows Applications

While the "Basic" in Visual Basic goes back to 1964, the "Visual" has far more recent origins. Nowadays, the majority of applications are written for at least one if not more of the Windows operating systems, which include Windows 3.x, 9 x, NT 4.0, ME, 2000, and XP. Figure 1 -1 shows a familiar Windows application, Notepad, which is included by default in the installation of all Windows operating systems.

Although the Windows operating system has virtually taken over the computer world, it has not been with us that long. Windows was not introduced until 1985, more than 20 years after the introduction of BASIC. Prior to then, applications were displayed and ran in a console, or text, mode. As Figure 1 -2 shows, applications in a console or text mode have a decidedly different and less rich appearance than Windows applications.

The difference between console and Windows applications is more than skin deep. They also behave very differently. Let's now look at both differences.
