Question

我有C应用程序，用于确定我的笔记本电脑何时打开电源。它仅在我打开此.exe文件时才有效

有没有办法让它在内核模式下工作？意思是我不想运行.exe但只是打开笔记本电脑并在电量不足时接收有关电源的消息。

这是我的.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 );

我不明白你为什么要在内核模式下运行这段代码......是不是作为服务运行了？

您应该将程序打包为Windows服务，然后在您的系统上安装该服务。没有必要进入内核级别。

如何将应用程序转换为内核模式运行代码？
