Net packets out of order problem

Hi,

When I execute this command :

Code: Select all
    Public Sub GetPays(ByVal cbo As Janus.Windows.EditControls.UIComboBox, Optional ByVal cbo2 As Janus.Windows.EditControls.UIComboBox = Nothing, Optional ByVal cbo3 As Janus.Windows.EditControls.UIComboBox = Nothing)
        Dim mySelectQuery As String = "SELECT `ID_Pays`,`Pays`, `Flag` FROM ztbl_country"
        Dim myCommand As New CoreLab.MySql.MySqlCommand(mySelectQuery, MySQLConnexion)
        cbo.Items.Clear()
        If Not cbo2 Is Nothing Then cbo2.Items.Clear()
        If Not cbo3 Is Nothing Then cbo3.Items.Clear()
        Try
            Dim myReader As CoreLab.MySql.MySqlDataReader = myCommand.ExecuteReader()
            ' Always call Read before accessing data.
            While myReader.Read()
                cbo.Items.Add(myReader.GetString(myReader.GetOrdinal("Pays")), myReader.GetString(myReader.GetOrdinal("ID_Pays")))

                If Not cbo2 Is Nothing Then
                    cbo2.Items.Add(myReader.GetString(myReader.GetOrdinal("Pays")), myReader.GetString(myReader.GetOrdinal("ID_Pays")))
                End If

                If Not cbo3 Is Nothing Then
                    cbo3.Items.Add(myReader.GetString(myReader.GetOrdinal("Pays")), myReader.GetString(myReader.GetOrdinal("ID_Pays")))
                End If

                Dim myBlob As CoreLab.MySql.MySqlBlob = myReader.GetMySqlBlob(myReader.GetOrdinal("Flag"))

                If Not myBlob.IsEmpty Then
                    cbo.Items(myReader.GetString(myReader.GetOrdinal("Pays"))).Image = New Bitmap(myBlob)
                    If Not cbo2 Is Nothing Then
                        cbo2.Items(myReader.GetString(myReader.GetOrdinal("Pays"))).Image = New Bitmap(myBlob)
                    End If
                    If Not cbo3 Is Nothing Then
                        cbo3.Items(myReader.GetString(myReader.GetOrdinal("Pays"))).Image = New Bitmap(myBlob)
                    End If
                End If

            End While
            ' always call Close when done reading.
            myReader.Close()
            cbo.SelectedItem = cbo.Items("Belgique")
            If Not cbo2 Is Nothing Then
                cbo2.SelectedItem = cbo.Items("Belgique")
            End If
            If Not cbo3 Is Nothing Then
                cbo3.SelectedItem = cbo.Items("Belgique")
            End If

        Finally
            myCommand.Dispose()
            mySelectQuery = Nothing
        End Try


The first query result an error as :
Net packet out of order : received [0], expected[59]

If I ignore this error an try to recall this fuction this error not appear !

Note:
the number in expected[xxx] is not same each time


Any idea to solve my problem ?

Thanks,

Probably you use MySQLConnexion variable from several threads.
Try to create a new MySQLConnexion each time.
What is your version of MySQL server?
Do you have this error each time when you execute the command?
Add to your Finally section myReader.Close() line.
