[dba-VB] ADO.Net Update SQL Server

Does ANYBODY know how to write a table back out to SQL Server?

All of my books show cute little examples of building up a data table 
manually then BINDING it to a control or whatever.  I am not finding 
anything with code example that shows how to WRITE changed data back to 
SQL Server.

I have managed to load a data table, write changes to the rows and 
now... I have to write it back out to SQL Server.  The table has the PK, 
NameToSplit, LName, FName etc etc.  What am I missing?

I desperately need help (yea, yea, not MENTAL help) and I need it 
quickly.  I have been trying to do this last piece for DAYS and I am not 
succeeding.
