No one needs to reinvent the wheel. This is a book full of
all shapes and sizes of ASP.NET wheels.
For example "Rendering Images to a Data Grid" or "Performing a
DNS Lookup" with the code to accomplish the task.
Virtually everything you might want to do and some you would be
afraid to try are covered in this well documented code heavy book.
All the examples are in VB.NET but C# code is available on the
companion web site.
Recommendation:
A must own for any ASP.NET coder.
