Idle - Hook - dll

Bonjour,

voila, j'ai trouve le code d'une dll permettant de savoir
depuis combien de temps le PC est inactif.
Mais voila, elle a un probleme, quelque fois elle passe
en idle alors que le pc est actif. Je ne trouve pas de solution, et je ne trouve aucun probleme similaire sur internet.

voila le code de la dll :

#include <windows.h> #include <crtdbg.h> /** * The following global data is SHARED among all instances of the DLL * (processes); i.e., these are system-wide globals. **/ #pragma data_seg(".IdleTrac") // you must define as SHARED in .def HHOOK g_hHkKeyboard = NULL; // handle to the keyboard hook HHOOK g_hHkMouse = NULL; // handle to the mouse hook DWORD g_dwLastTick = 0; // tick time of last input event LONG g_mouseLocX = -1; // x-location of mouse position LONG g_mouseLocY = -1; // y-location of mouse position #pragma data_seg() #pragma comment(linker, "/section:.IdleTrac,rws") HINSTANCE g_hInstance = NULL; // global instance handle /** * Get tick count of last keyboard or mouse event **/ __declspec(dllexport) DWORD IdleTracker_GetLastTickCount() { return g_dwLastTick; } /** * Keyboard hook: record tick count **/ LRESULT CALLBACK KeyboardTracker(int code, WPARAM wParam, LPARAM lParam) { if (code==HC_ACTION) { g_dwLastTick = GetTickCount(); } return ::CallNextHookEx(g_hHkKeyboard, code, wParam, lParam); } /** * Mouse hook: record tick count **/ LRESULT CALLBACK MouseTracker(int code, WPARAM wParam, LPARAM lParam) { if (code==HC_ACTION) { MOUSEHOOKSTRUCT* pStruct = (MOUSEHOOKSTRUCT*)lParam; //we will assume that any mouse msg with the same locations as spurious if (pStruct->pt.x != g_mouseLocX || pStruct->pt.y != g_mouseLocY) { g_mouseLocX = pStruct->pt.x; g_mouseLocY = pStruct->pt.y; g_dwLastTick = GetTickCount(); } else if (wParam==WM_NCLBUTTONDOWN || wParam==WM_NCLBUTTONUP || wParam==WM_NCLBUTTONDBLCLK || wParam==WM_NCMBUTTONDOWN || wParam==WM_NCMBUTTONUP || wParam==WM_NCMBUTTONDBLCLK || wParam==WM_NCRBUTTONDOWN || wParam==WM_NCRBUTTONUP || wParam==WM_NCRBUTTONDBLCLK || wParam==WM_LBUTTONDOWN || wParam==WM_LBUTTONUP || wParam==WM_LBUTTONDBLCLK || wParam==WM_MBUTTONDOWN || wParam==WM_MBUTTONUP || wParam==WM_MBUTTONDBLCLK || wParam==WM_RBUTTONDOWN || wParam==WM_RBUTTONUP || wParam==WM_RBUTTONDBLCLK) { g_dwLastTick = GetTickCount(); } } return ::CallNextHookEx(g_hHkMouse, code, wParam, lParam); } /** * Initialize DLL: install kbd/mouse hooks. **/ __declspec(dllexport) BOOL IdleTracker_Start() { if (g_hHkKeyboard == NULL) { g_hHkKeyboard = SetWindowsHookEx(WH_KEYBOARD, KeyboardTracker, g_hInstance, 0); } if (g_hHkMouse == NULL) { g_hHkMouse = SetWindowsHookEx(WH_MOUSE, MouseTracker, g_hInstance, 0); } _ASSERT(g_hHkKeyboard); _ASSERT(g_hHkMouse); g_dwLastTick = GetTickCount(); // init count if (!g_hHkKeyboard || !g_hHkMouse) return FALSE; else return TRUE; } /** * Terminate DLL: remove hooks. **/ __declspec(dllexport) void IdleTracker_Stop() { BOOL bResult; if (g_hHkKeyboard) { bResult = UnhookWindowsHookEx(g_hHkKeyboard); _ASSERT(bResult); g_hHkKeyboard = NULL; } if (g_hHkMouse) { bResult = UnhookWindowsHookEx(g_hHkMouse); _ASSERT(bResult); g_hHkMouse = NULL; } } /** * DLL's entry point **/ int WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved) { switch(dwReason) { case DLL_PROCESS_ATTACH: DisableThreadLibraryCalls(hInstance); g_hInstance = hInstance; break; case DLL_PROCESS_DETACH: //we do an unhook here just in case the user has forgotten. IdleTracker_Stop(); break; } return TRUE; } /** * This is to prevent the CRT from loading, thus making this a smaller * and faster dll. **/ extern "C" BOOL __stdcall _DllMainCRTStartup( HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) { return DllMain( hinstDLL, fdwReason, lpvReserved ); }

Voila si vous avez une idee, ca m'interresse.

D'avance merci.
