如何將應用程序變成內核模式運行代碼？

Question

我有C應用程序，用於確定何時電源接通\關我筆記本上。 當我打開該.exe文件

有沒有一種方法，使之在內核模式下工作，它的工作原理而已？ 意思我不想運行.exe，但只要打開筆記本電腦，並免費獲贈味精有關電源時，功率低。

這裏是我的.exe：

#include <windows.h> 

const char g_szClassName[] = "myWindowClass"; 




// Step 4: the Window Procedure 
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) 
{ 
short x ; 

SYSTEM_POWER_STATUS status; 


switch(msg) 
{ 
case WM_CLOSE: 
    DestroyWindow(hwnd); 
    break; 
case WM_DESTROY: 
    PostQuitMessage(0); 
    break; 

case WM_POWERBROADCAST: 
       switch (wParam) 
        { 
         case PBT_APMPOWERSTATUSCHANGE : 
          x = GetSystemPowerStatus(&status); 
          if (x > 0) // function succeeded 
           { 
            if (status.ACLineStatus == 1) 
            { 
             printf("power is off"); 
             MessageBox(NULL, "power is on" , "NOTICE" ,MB_OK); 
            } 
            else if (status.ACLineStatus == 0) 
            { 
             printf("power is on"); 
             MessageBox(NULL, "power is off" , "NOTICE" ,MB_OK); 
            } 
            else 
            { 
             printf("unknown"); 
             MessageBox(NULL, "unknown status" , "ERROR" ,MB_OK); 
            } 
           } 
          else 
           { 
           LPSTR str = "function failed in providing information"; 
           MessageBox(NULL , str, "ERROR", MB_OK); 
           } 
          break; 
         case PBT_POWERSETTINGCHANGE: 
          x = GetSystemPowerStatus(&status); 
          if (x > 0) // function succeeded 
          { 
           if (status.ACLineStatus == 1) 
           { 
            printf("power is off"); 
            MessageBox(NULL, "power is on" , "NOTICE" ,MB_OK); 
           } 
           else if (status.ACLineStatus == 0) 
           { 
            printf("power is on"); 
            MessageBox(NULL, "power is off" , "NOTICE" ,MB_OK); 
           } 
           else 
           { 
            printf("unknown"); 
            MessageBox(NULL, "unknown status" , "ERROR" ,MB_OK); 
           } 
          } 

          break; 
         default: 
          MessageBox (NULL , "nothing" , "------" , MB_OK); 
        } 
       break; 
case WM_MOUSEMOVE: 
    if (wParam == MK_LBUTTON) 
     MessageBox(NULL, "mouse was clicked", "check", MB_OK); 
    break; 
default: 
    return DefWindowProc(hwnd, msg, wParam, lParam); 
} 
return 0; 
} 

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,

我不明白你爲什麼要運行在內核模式下的代碼...是不夠作爲服務運行？

你應該收拾你的程序作爲Windows服務，然後在系統上安裝的服務。沒有必要去內核級別。
