Disadvantages of Visual Basic
Like other programming languages, Visual Basic (VB) has also its own advantages and limitations. Visual Basic is powerful language but it is not suit for programming, It is much slower than other languages. It is a proprietary programming language written by Microsoft so programs written in Visual basic cannot, easily, be transferred to other operating systems. The applications which are doveloped in Visual Basic are working only on Windows Operating systems only. Visual Basic is not very useful for making programs that use a lot of processing time such as the games
Following are the disadvantage of Visual Basic:
1. VB is still much slower than most other programming languages ;
2. VB was not a type-safe language;
3. VB does not allow developing the multithreaded applications;
4. VB is powerfull language ,but it’s not suit for programming really sophisticated games;
5. VB is only for the application programing;
6. It is Completely Graphical in Nature , So it Requires more Memory to Store the Package;
7. VB is not object oriented;
8. Deployment is time consuming as all the components must be registered in the Windows registry;
9. VB DLL does not support side-by-side execution;
10. The VB support OOP concepts,but not support fully;
11. No multithreading mechanism;
12. VB does not support exception handling;
13. The dlls of the VB is mapped with the Registry so the overhead on the registry is increased;
14. VB is not Object oriented bcoz it don’t hv classes it hv only the functions so we hv to learn the functions for the programing we can’t import the classs.
