下面兩個按鈕屬性含義?先謝謝!
下面的c語句其中：
“t_record_1","day_1","time_hour_1","time_min_1","time_sec_1","t_code_1","t_valve_1",
共記100條（因為字?jǐn)?shù)限制沒有寫全）

佳答案

數(shù)據(jù)保存按鈕
把700個浮點(diǎn)數(shù)變量aa[i]的數(shù)據(jù)保存到文本文件d:\thj.txt中，同時保存?zhèn)€d:\thj.bak備份
數(shù)據(jù)輸入按鈕
把文本文件d:\thj.txt的記錄取出并寫的變量浮點(diǎn)數(shù)變量aa[i]中（700個數(shù)據(jù)）

說白了數(shù)據(jù)配方的保存和取出功能
