Private Sub LoadScore()
    
        Dim sql As String = "SELECT names,score FROM HighScore"
        sql &= " Where (level ='" & Level & "')"
        sql &= " ORDER BY score DESC"
        Dim cmd As New OleDbCommand(sql, conn)
        Dim da As New OleDbDataAdapter(cmd)
        Dim datascore As New DataSet

        da.Fill(datascore, "HighScore")
        ScoreLoad(1) = data.Tables("HighScore").Rows(0)("score")
        ScoreLoad(2) = data.Tables("HighScore").Rows(1)("score")
        ScoreLoad(3) = data.Tables("HighScore").Rows(2)("score")
        ScoreLoad(4) = data.Tables("HighScore").Rows(3)("score")
        ScoreLoad(5) = data.Tables("HighScore").Rows(4)("score")
