Need help with notes field for database application - VB.NET and SQL 2000

I need to be able to insert notes in a database application using VB.NET front end and SQL 2000 as the database backend. Here is how I would like to be able to insert notes.

I have a richtextbox, textbox and button on a form. I would like to be able to enter text into the textbox and have it add a new line to the richtextbox when I click on the button. I know this can be done, but I'm pulling a blank on getting the notes to show up in the richtextbox line by line and then be update in the varbinary notes field in sql. Please help! Thanks in advance!!!

Perform the following actions in OnClick event handler of your button
1. Open connection to the database
2. Create INSERT query with appropriate parameters: from the richtextbox and the textbox
3. Execute the above query
4. Close connection

HTH,

it was load / save blob (streams etc.), from that, I worked this out for the db side, as for the line by line into a rich text box, try

            Me.RichTextBox1.Text = Me.RichTextBox1.Text & Me.TextBox1.Text & ControlChars.CrLf

db load / save

            ' load data from sql dataset
            Try
                  Dim cnn As SqlClient.SqlConnection
                  Dim strConn As String = "Integrated Security=true;initial catalog=Northwind"
                  Dim sql As String = "SELECT * FROM Employees WHERE EmployeeID=1"
                  cnn = New SqlClient.SqlConnection(strConn)
                  cnn.Open()
                  Dim cmd As SqlClient.SqlCommand = cnn.CreateCommand

                  cmd.CommandText = sql
                  cmd.CommandType = CommandType.Text
                  Dim ds As DataSet = New DataSet
                  Dim da As New SqlClient.SqlDataAdapter
                  da.SelectCommand = New SqlClient.SqlCommand(sql, cnn)
                  da.Fill(ds)

                  Dim stream As New IO.FileStream("c:\temp2.rtf", IO.FileMode.OpenOrCreate, IO.FileAccess.Write)
                  Dim encoding As New System.Text.ASCIIEncoding
                  Dim rtf As [Byte]() = encoding.GetBytes(ds.Tables(0).Rows(0).Item("Notes").ToString)
                  stream.Write(rtf, 0, rtf.Length)
                  stream.Close()
                  Me.RichTextBox1.LoadFile("c:\temp2.rtf")

                  cnn.Close()
            Catch ex As Exception
                  MessageBox.Show(ex.Message)
            End Try



            ' save data to sql using dataset
            Try
                  Dim connect As New SqlClient.SqlConnection("Initial Catalog = Northwind;Data Source =(local);User ID=sa;password=;Connect Timeout = 20")

                  connect.Open()

                  Dim command As String = "SELECT * from employees WHERE EmployeeID=1"
                  Dim ds As New DataSet

                  Dim adaptor As SqlClient.SqlDataAdapter = New SqlClient.SqlDataAdapter(command, connect)
                  Dim cmdBuilder As SqlClient.SqlCommandBuilder = New SqlClient.SqlCommandBuilder(adaptor)

                  adaptor.Fill(ds)

                  Me.RichTextBox1.SaveFile("c:\temp.rtf")
                  Dim fs As New IO.FileStream("c:\temp.rtf", IO.FileMode.Open, IO.FileAccess.Read)
                  Dim rtf(255) As Byte
                  fs.Read(rtf, 0, CType(fs.Length, Integer))
                  Dim i As Integer
                  Dim encoding As New System.Text.ASCIIEncoding
                  ds.Tables(0).Rows(0).Item("Notes") = encoding.GetString(rtf, 0, Convert.ToInt32(fs.Length))
                  fs.Close()

                  adaptor.UpdateCommand = cmdBuilder.GetUpdateCommand()
                  Debug.WriteLine(cmdBuilder.GetUpdateCommand.CommandText)

                  Dim intUpdated As Integer
                  intUpdated = adaptor.Update(ds.Tables(0))

                  MessageBox.Show("Updated: " & intUpdated.ToString)

            Catch ex As Exception
                  MessageBox.Show(ex.Message)
            End Try
