Hi Siva,
I think there are two separated topics in your question:
How to synchronize views:"Synchronization" usually means the subjects should be completely the same and in this mean the synchronization is "easy". But if you want to synchronize different views (different camera position etc.), you and nobody else have to define how the synchronization should work. It can be e.g. zoom will change in the same ratio, but probably not to the same absolute value ... it depends completely on what the final result should be.
What language should be used: To work with view events, MicroStation VBA is not a good choice. As interpreted language running outside MicroStation with limited API, it will be always slow and probably fragile, some information about view are accessible using wrappers to MDL only, which is another complication. MicroStationAPI or MDL compiled into native code is much better.
With regards,
Jan
