I have a simple form in VB2005.  I added a Binding source that connects to an Access Database and a Binding Navigator.  I dragged the data fields onto the form and can view and navigate the data.  I do not know how to change the data ie. Add Delete or Edit.  I understand that I am only changing the dataset.  I need to also update the database with the changes.  Also if possible can the changed be made w/o clicking an update button.  If not it's OK.  Thank you in advance!

You need to create the command add, delete, update when u selec the database............ E.g..

DaGeneral = New OleDbDataAdapter()
DaGeneral.SelectCommand = New OleDbCommand("SELECT * FROM [TABLENAME]", g_objconn)

Dim CB As OleDbCommandBuilder
CB = New OleDbCommandBuilder(DaGeneral)
DaGeneral.InsertCommand = CB.GetInsertCommand()
DaGeneral.UpdateCommand = CB.GetUpdateCommand()
DaGeneral.DeleteCommand = CB.GetDeleteCommand()
DsGeneral = New DataSet()
DaGeneral.Fill(DsGeneral, "GENERAL")
GeneralTable = DsGeneral.Tables("GENERAL")
GenDatasource = New BindingSource(DsGeneral, "GENERAL")
GenDatasource.DataSource = GeneralTable

After change the data in binding fields (TextBox)
DaGeneral.Update --- update the database
DsGeneral.AcceptChanges()

You can put this code in Form Load.....

2. put the code suggest ....
3. binding the datasource to textbox
4. create a button for update...

**Note :- your table should have primary key define for commandbuilder ...
