Just as Microsoft has been adding more and more features to Windows and the Windows API over the past decade ,Visual Basic and C++ have undergone expansion. Although Visual Basic and C++ have ended up as hugely powerful languages as a result of this, both languages also suffer form problems due to the legacies of how they have evolved. In the case of Visual Basic 6 and earlier, the main strength of the language was the fact that it was simple to understand and didn’t make many programming tasks easy,largely hiding the details of the Windows API and the COM component infrastructure from the developer.The downside to this was that Visual Basic was never truly object-oriented, so that large applications quickly become disorganized and hard to maintain .As well as this ,because Visual Basic `s syntax was inherited from early versions of BASIC(which ,in turn, was designed to be intuitively simple for beginning programmers to understand,rather than to write large commercial applications), it didn’t really lend itself to well-structured or object-oriented programs. C++,on the other and, has its roots in the ANSI C++ language definition. It isn’t completely ANSI compliant for the simple reason that Microsoft first wrote its C++ compiler before the ANSI definition had become official, but it comes close. Unfortunately, this has led to two problems.First, ANSI C++ has its roots in a decade-old state of technology, and this shows up in a lack of support for modern concep
