Hello,
Which VB version can make 64-bits programs?

Thank you

yxq,

That depends what you mean with 64 bits programs. It is not so that on the
new 64 Windows OS the 32 bits programs don't work.

On many demands from the classic VB developpers has Microsoft decided not to
optimize the 64bit Net version for 64bit use. The integer stays using 32
bits and with that has a slightly lower performance than it could have been.

When you want to optimize it than you have probably to change all integers
to Int64 yourself.

Well i folowed multiple webcasts about 64 bit programming

here is a nice resource :
http://www.route64.net/

And i understood that the .Net framework will handle most of the job ( you
do not have to deploy seperate versions etc etc )
however it is possible in 1 executable to take advantage of the 64 bit
processing power on 64 bit systems while the same program will still run on
a 32 bit system

No currently existing version can compile 64-bit applications.

Well, I was referring to released final versions.
