WavesurroundDEMO程式我一直都沒怎麼看，抱歉。――你說的過期判斷不知怎麼回事，DSP_WA3D.DLL裡面找不到getsytstemtime或者getlocaltime等類似的時間函式，我也搞不清它是怎樣判斷時間過期的。倒是那個NAG視窗很吸引人，本來還不知怎麼入手的，後來找了個resource
hacker可以修改資源的那種工具，把winamp的plug-in目錄下的那個dsp_wa3d.dll的NAG對話方塊資源給刪除就萬事大吉了，好笑不好笑？
不過這不是正兒八經的方法。你寄給我的那個patch中對DSSP_WA3D.DLL進行了兩處改動，一個是去掉DEMO的nag，一個是解除時間過期。改的地方分別是：
去NAG視窗（其實就是跳過MESSAGEBOXA）：

至於這種浮點指令和時間判斷有什麼關係，就不清楚了。你所說的下文部分只是根據過期標誌而作出的介面修改部分，光改它們只會引起介面的變化，內在功能即限制還是不變。
