Db problem in Crystal report

Question

I am trying to build a Crystal report VisualStudio.NET for an VB.NET
application. I would like to build a report that doesn't connect to
any particular database at design time because I am planning to pass a
dataset to the report at runtime. From what I have read, it sounds
like unbound fields might be the answer. However, I am having trouble
figuring out how to bind these unbound fields to my dataset at
runtime.
