well its kind of a given with the amount of changes/improvments they are making to vb that there will be compatibility problems. ive been working with vb since
vb3 when i was a teenager and ive grown up through the changes they have made to vb. but the sacrfices of adjusting to the new, benefits you with the rewards of growth and power. ive read all the prospected capabilities of vb7/net and i for one can't wait for it to come out.
microsoft is pushing c# more because thats where the challenge for them is, java is very widley used an accepted.
its hard to get programmers to drop a language they are good at and like. microsoft isnt worried about anyone dropping vb cause it is so widley used, they know the support for vb is already there. there are so many programmers that live and die by vb that it will probably never go away. so microsoft knows that they will have plenty of support for vb7, thus no need to push it hard.
or thats my take... remember microsoft is in it for the money... so they push where there weak...
