Hi,
My problem: Merging two datasets deletes parent elements, preserves
all children.
I've created two dataSets. Each use the same schema, parent-child
nested tables.
The first dataSet is loaded with historical data read from an XML
file. The second dataSet has current data filled from a dataGrid.

Why does this code work?
I am new to C# and have been studying this piece of code. It loops
through an Adjacency Matrix table to populate a tree view. I have two
questions about why this code works.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
