        Try
            'Try to open the connection
            conn.Open()
            Return True
        Catch ex As MySqlException

        Dim myCommand As New MySqlCommand

        Dim myData As MySqlDataReader

        Dim SQL As String
        'Our MySQL Query
        Dim Email As String = txtEmail.Text.Replace("'", "\'")

        SQL = "SELECT * FROM `users` WHERE `email` = '" + Email + "' AND `password` = '" + Password + "'"

        myCommand.Connection = conn
        myCommand.CommandText = SQL
        myAdapter.SelectCommand = myCommand
        Try
            'Try to execute the query
            myData = myCommand.ExecuteReader()
            myData.Read()
            If myData.HasRows = 0 Then 'Checkes if a row with the email and password exist.

                myData.Close()
            Else
                'if yes outputs this:
                MsgBox("Welcome " + myData.GetString("fname") + "!.")
                myData.Close()

            End If
        Catch ex As MySqlException
