Hi,

I have been researching this myself - here are a few bits of info I have found

1) search MSDN express free download

2) http://www.codeproject.com/KB/database/VB_DGV_UpdatingBoundDB.aspx  -- this maybe helpful

3) http://www.itwriting.com/pcw/vbdotnetdata.php  -- first link is to a simple database code download

Hope this might help.

Ok, but do you will delete the records in the datagridview directly OR you have some textbox's, checkbox's, etc, to fill the information and then you have an insert button ?
If you will use the datagridview for that, the code I showed you will be enough. It saves also the add, delete and update actions.

Then you just have to insert in the mySQL table. Here's an example for SQL and you only need to change the classes (SqlConnection to mySQLCommand, etc)
        ' Add this Imports to the top of the page
        Imports System.Data.SqlClient
 
        Dim myConnectionString As String = _
              "Data Source=.\SQLEXPRESS;AttachDbFilename='C:\myDatabase.mdf';" & _
              ";Integrated Security=True;User Instance=True"
 
        ' Defines the T-SQL command
        Dim SQL As String = "INSERT INTO myTable([username], [date]) VALUES (@username, @date);"
 
        ' Create a new connectio class
        Using connection As New SqlConnection(myConnectionString)
 
            ' Creates the command that will do the T-SQL
            Using command As New SqlCommand(SQL, connection)
 
                ' Add's the parameters that will be inserted
                command.Parameters.Add("@username", SqlDbType.VarChar).Value = "jpaulino"
                command.Parameters.Add("@date", SqlDbType.DateTime).Value = DateTime.Now
 
                connection.Open()
 
                ' Executes the command
                Dim x As Integer = command.ExecuteNonQuery()
                If x < 1 Then
                    MessageBox.Show("No records inserted.")
                End If
 
            End Using
 
        End Using
