Hi all,
C++ is more efficient and faster than VB, right?
well as I was developing an app, I learned that VB can do things a lot faster than VC++, like Ms word Automation!!!
I wrote an app that populate formfields, many of them, it took quite long in VC++, and all the automation overhead. I then played with VB (I am not a VB programmer) only to find out that it was much faster. someone please help.
thanks
Are you comparing performance or development time?

I am comparing performance
The performance of the VB version i far better.
I don't understand it at all
as I recall and I'm probably talking out my rear since I have not confirmed this via disassembly...but VB is optimized for the above.Quote:

if that is the case, then it makes sense
Its the only logical explanation
Cheers
Yes, but that doesn't mean that it's necessarily slower in C++. You can actually get better speed in C++ for Word automation than in VB, provided that you optimise your code correctly. For example, you can use vtbl calls instead of IDispatch if you know which Office version you're using. In case you don't know, you can cache the dispids of the required functions etc.Quote:
