Hi DH,
I won't begin to answer all of your questions, but vb .net is here to stay;
it's robust, cutting edge, capable of anything, provides data access and oop
features as effective as found in any language, and MS will be supporting it
for a long, long time. It's not only in itself feature rich, but the 3rd
party support is remarkable. It is the future, no less than any of the
visual studio languages, namely c#.
HTH,
Bernie Yaeger
