I'm trying to save the query with DataSet()
As you can see in the part where it says: '
here dataset i dont know how it
That should be what I need is something in OleDB
con.Open()
adaptadordatos.Fill(conjuntoDatos, "Alumnos")
con.Close()
But I am using MYSQL vb.net 2010 I do not find much documentation about. I could use a good guide to good mysql - vb.net
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
Dim Conexion As New MySql.Data.MySqlClient.MySqlConnection
Dim CadenaSQL As String = "SELECT * FROM Alumnos ORDER BY nombre"
Dim CadenaConexion As String = "Data Source=localhost;" & _
"Database=" & "NuevaBD" & ";" & _
"User Id=root;Password="
Dim Comando As New MySql.Data.MySqlClient.MySqlCommand(CadenaSQL)
Conexion = New MySql.Data.MySqlClient.MySqlConnection(CadenaConexion)
Try
Dim conjuntoDatos As New DataSet()
Conexion.Open()
'here dataset i dont know how it
'Comando.Fill(conjuntoDatos, "Alumnos")
Conexion.Close()
Dim tabla As DataTable
tabla = conjuntoDatos.Tables("Alumnos")
Dim fila As DataRow
Me.ListaAlumnos.Items.Clear()
For Each fila In tabla.Rows
' Muestra los datos en un ListBox
Me.ListaAlumnos.Items.Add(fila.Item("Nombre") & " " & fila.Item("Apellidos"))
Next
Catch ex As MySql.Data.MySqlClient.MySqlException
MsgBox("No se ha podido establecer " & vbCrLf & _
"la conexión con la base de datos.", MsgBoxStyle.Critical)
Finally
Select Case Conexion.State
Case ConnectionState.Open
Conexion.Close()
End Select
End Try
End Sub

Fill()
is a method on a Data Adapter, not a Command
. Even with the language barrier, that seems pretty heavily implied here:
adaptadordatos.Fill(conjuntoDatos, "Alumnos")
So create a data adapter...
Dim myAdapter As MySqlDataAdapter = New MySqlDataAdapter(CadenaSQL, Conexion)
myAdapter.Fill(conjuntoDatos, "Alumnos")
