Following are the disadvantage of VB :
1. VB is not object oriented.
2. VB DLL does not support side-by-side execution
3. Deployment is time consuming as all the components must 
be registered in the Windows registry.

1.The VB support OOP concepts,but not support fully.

2.VB does not support exception handling.

3.No multithreading mechanism.

kamal....

The dlls of the VB is mapped with the Registry so the 
overhead on the registry is increased.
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.
vb is only for the application programing but nw the 
scenario is for web applications?

VB dosent use magic
