        Me.Close()
    End Sub

    Private Sub Cancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Me.Close()
    End Sub

        End
    End Sub
Private Sub OK_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click

        MySQLConnection.ConnectionString = "server=db4free.net;Port=3306; User ID=db4freeusername; password=db4freepassword; database=nameofyourdatabase"
        MySQLConnection.Open()

        Dim MyAdapter As New MySqlDataAdapter
        Dim SqlQuary = "SELECT * From nameofthetable WHERE Username='" & UsernameTextBox.Text & "' AND password = '" & PasswordTextBox.Text & "';"
        Dim Command As New MySqlCommand
        Command.Connection = MySQLConnection
        Command.CommandText = SqlQuary
        MyAdapter.SelectCommand = Command
        Dim Mydata As MySqlDataReader
        Mydata = Command.ExecuteReader
        If Mydata.HasRows = 0 Then
