Why Use Visual J++?,ld. Java is the only language you can use to create WORA (write once run anywhere) applications and applets which can be run on any type of computer. Applets are applications written in Java which can run within a browser environment such as Internet Explorer. They allow you to create dynamic intera

If you have tried some of the examples in the previous chapter, you may have found that your programs did not look exactly the same as the figures. This is because you ma

In addition to Windows.EXE files you can also create ActiveX controls. Visual J++ includes a powerful visual environment for creating these applications, which will look very fa
