WavesurroundDEMO程序我一直都没怎么看，抱歉。——你说的过期判断不知怎么回事，DSP_WA3D.DLL里面找不到getsytstemtime或者getlocaltime等类似的时间函数，我也搞不清它是怎样判断时间过期的。倒是那个NAG窗口很吸引人，本来还不知怎么入手的，后来找了个resource hacker可以修改资源的那种工具，把winamp的plug-in目录下的那个dsp_wa3d.dll的NAG对话框资源给删除就万事大吉了，好笑不好笑？不过这不是正儿八经的方法。你寄给我的那个patch中对DSSP_WA3D.DLL进行了两处改动，一个是去掉DEMO的nag，一个是解除时间过期。改的地方分别是：
去NAG窗口（其实就是跳过MESSAGEBOXA）：

至于这种浮点指令和时间判断有什么关系，就不清楚了。你所说的下文部分只是根据过期标志而作出的界面修改部分，光改它们只会引起界面的变化，内在功能即限制还是不变。
