參考 http://groups.google.com/groups?hl=zh-TW&lr=&ie=UTF-8&oe=UTF-8&threadm=3c6480e3_2@dnews&rnum=11&prev=/groups?q="BROADCAST_QUERY_DENY"&hl=zh-TW&lr=&ie=UTF-8&oe=UTF-8&start=10&sa=N 測試了一下,發現雖然可以偵測的到休眠的Message,但是卻仍然無法阻止OS進入 休眠模式,可否請教一下,以下的寫法是否仍有問題,還是得要用HOOK來寫 class TForm1 : public TForm { __published: // IDE-managed Components private: // User declarations TWndMethod OldFormProc; void __fastcall NewFormProc(TMessage &Msg); public: // User declarations __fastcall TForm1(TComponent* Owner); }; __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { OldFormProc=Form1->WindowProc; Form1->WindowProc=NewFormProc; } void __fastcall TForm1::NewFormProc(TMessage &Msg) { switch(Msg.Msg) { case WM_POWERBROADCAST: if((Msg.WParam == PBT_APMQUERYSUSPEND)) { Msg.Result = BROADCAST_QUERY_DENY; Dispatch(&Msg); return; } break; } OldFormProc(Msg); }

NT 應該是 call SetSystemPowerState 進去的. 其中第二個參數: fForce [in] Forced suspension. If TRUE, the function broadcasts a PBT_APMSUSPEND event to each application and driver, then immediately suspends operation. If FALSE, the function broadcasts a PBT_APMQUERYSUSPEND event to each application to request permission to suspend operation. 你可能要去看一下差異. force = true 好像是不能被攔截的... MSDN的說法是, OS給你20秒, 超過了就直接幹掉 process. --- 小葵..小葵有很多的夢想 等待薰下班回家, 並準備晚飯跟洗澡水 薰回家的時候, 對你說一聲 歡迎回家 在休息的日子, 兩個人坐在屋外的走廊上, 品嚐著我親自作的點心 薰如果累了, 替他搥搥肩; 冷了, 和薰一起擠著被爐 但是, 但是... 小葵最大的心願是...成為薰的..成為薰的妻子
