之前有問一篇，尚未有明確的答案，最近一直覺得ForegroundIdleProc這隻func可能可行，終於有空自已try了一下，不過無法成功，完全是照著ForegroundIdleProc、SetWindowsHookEx上的說明照表操課寫的，不知道是那裏有錯還是概念完全不對，大家有空幫我看一下，謝謝! >< class="code"> ~~~ #pragma resource "*.dfm" TForm1 *Form1; HHOOK HIdleHook; DWORD MyIdleHookProc(int code,DWORD wParam,LONG lParam); <---自訂的ForegroundIdleProc function HINSTANCE TestAppIns; DWORD TestAppThreadId; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- void __fastcall TForm1::FormCreate(TObject *Sender) { //開啟另一隻ap，並希望監控它是否變成idle TestAppIns=ShellExecute(NULL,NULL,"C:\\testidle.exe",NULL,NULL,SW_SHOW); Sleep(500); HWND hwnd=FindWindow(NULL,"fuckdead"); <---由這隻ap的Form->Caption抓Form的hwnd if (hwnd==NULL) ShowMessage("Can't find the program!"); DWORD xx; TestAppThreadId=GetWindowThreadProcessId(hwnd,&xx); } //--------------------------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) { HIdleHook=SetWindowsHookEx(WH_FOREGROUNDIDLE,(HOOKPROC)MyIdleHookProc,TestAppIns,TestAppThreadId); if (HIdleHook==NULL) ShowMessage("Can't Hook in!"); } //--------------------------------------------------------------------------- void __fastcall TForm1::FormClose(TObject *Sender, TCloseAction &Action) { UnhookWindowsHookEx(HIdleHook); } //--------------------------------------------------------------------------- DWORD MyIdleHookProc(int code,DWORD wParam,LONG lParam) { Form1->Memo1->Lines->Add("This App is idle now"); if(code < 0) { return CallNextHookEx(HIdleHook,code,wParam,lParam); } return 1; <---實在不知道要return什麼 } //---------------------------------------------------------------------------
