Upgrade your Visual
Basic 6.0 applications to Visual Basic .NET with programming tips, tricks, and
side-by-side code comparisons direct from the source—Microsoft.
Microsoft Visual Basic .NET offers remarkable power and
flexibility, with richer object models for data, forms, transactions, and more.
But you must upgrade applications before they’ll compile and run in the
Microsoft .NET environment. Get the in-depth technical details you need to
upgrade Visual Basic applications efficiently with this upgrade-specific
reference. Learn about advanced Visual Basic .NET functionality such as
inheritance, multithreading, drag-and-drop XML Web services, RAD programmability
for servers, the forms package, and more. Examine side-by-side code examples,
and learn to evaluate which projects can benefit from an upgrade and which might
function best in a mixed-code environment. And get programming tips and tricks
