that it looks as if my data adapter is trying to update the Scratchpad3, but what I need it to update is ExceptionsEdit. My question is, how do I get my data to post to the ExceptionsEdit table in my database rather than trying to post back to the Scratchpad3?

is there a way to update a database row with the update command by first defining all parameters and then all values just like you can in the insert command? "insert into table1 (parameter1,parameter2,....) values (value1, value2,....)"something like "set table1 (parameter1, parameter2) values (value1,value 2,...) where ...."?because I only know the syntax to define each parameters value "set table parameter1=value, parameter2=value2... where"

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

Okay, I've never used "THROW NEW EXCEPTION" before, and I'm having a hard time understanding it completely.
When a handled error occurs (in a try..catch block), what should I do?
I display a message to the user already in the catch block.
I want to be able to log all errors to a SQL database.
Previously, I would always write a method called LogError, pass the exception into the sub, and it would log it to a SQL database. I'm not sure if there's a built in function for this or not.This will tell the user that there is an error. If I put a call out to LogError(ex) above the dim d as new dlgexception line, then it could log it in the SQL server.
I just feel that I am not doing this the right way.And I am very confused about the THROW NEW EXCEPTION. Why would you ever ned to throw an exception? Wouldn't you just handle it? What is the point?And, why would you throw an error inside of a Catch statement? I seen this done in examples. If the error was already thrown (which sends it to the Catch block), why would you throw it a second time?

An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex)
dr.Delete()
dbAdp.Update(dbDset.Tables("addresses"))
