寝室有一哥们是夜猫子，白天睡得不起来，晚上龙精虎猛，熬夜上网，虽然没开音箱，但是耳机漏音严重，而本人睡觉对环境要求很高，没办法，弄了个这玩弄放到他电脑里，再弄个settimer，每秒循环一次，从此世界清净很多了

调用如下，最好弄个settimer
program minvol;

uses
Windows,funVolume;


begin
SetVolume(Master,10000);
SetVolume(WaveOut,20000);
SetVolume(Microphone,20000);
end.

我们寝室也有个额啊！
电脑有密码怎么搞啊！嘎嘎····

oopww 发表于 2010-9-25 13:18:24

我觉得最好是把Windows Audio这个服务给他停止了！哈哈·····
世界安静了，河蟹了！
哈哈·····

设了密码？只要不是开机密码，就用pe进去，如果是开机密码，就强行放电呗
