Re: How to shutdown your computer using C++?

Something like this

C++ Syntax (Toggle Plain Text)
#include <iostream>
using namespace std;
 
int main ()
{
 
system("shut down -s -t 10");
return 0; 
 
}
#include <iostream>
using namespace std;

int main ()
{

system("shut down -s -t 10");
return 0; 

}

Shuts it down in ten seconds this is using dev c++

Re: How to shutdown your computer using C++?

Firstly, don't use sysrtem. use the function given to you by AncientDragon.

Secondly for an example, read the page it has a link to one.
Thirdly, that page tells you what parameters are needed, what they could be and what they do. Also it tells you what headers you need etc.

Please read information when someone points you to it, they don't do it for fun. They do it to try and help.

Re: How to shutdown your computer using C++?

Ok thankyou Chris for that abusive and useless post. (If I didnt need help I wouldnt have posted)

If someone can give me an example using ExitWindowsEx(), like power_computer tried to give me one using system("").

My attemps have included:

cpp Syntax (Toggle Plain Text)
 ExitWindowsEx(EWX_POWEROFF, SHTDN_REASON_MAJOR_OTHER);
 // AND
system("shutdown -s -t 180");
 ExitWindowsEx(EWX_POWEROFF, SHTDN_REASON_MAJOR_OTHER);
 // AND
system("shutdown -s -t 180");

So any ideas?

Thanks, Regards X
Thanks

Re: How to shutdown your computer using C++?

Delete line 3 (system(...) because its not needed. Otherwise, your line #1 looks ok to me, as long as you are running as administrator account.

Re: How to shutdown your computer using C++?

Ya they were just my attemps nothing works, this is my whole code below.
I am assuming that my ExitWindowsEx line is fine? (Whoops my internet is lagging didnt see ur second line)
Am I missing include files? Variables? Etc? I have vista also.
So what looks to be the problem?

cpp Syntax (Toggle Plain Text)
// Include Files
#include <iomanip>
#include <iostream>
#include <stdio.h>
#include <time.h>
#include <windows.h>
using namespace std;
 
int main () {
    // Shutdown
    cout << "Shutdown Complete!" << endl;  
ExitWindowsEx(EWX_POWEROFF, SHTDN_REASON_MAJOR_OTHER);
    //system("shutdown.exe -s -t 180");
 
    // Return Carriage
    return 0;
}
// Include Files
#include <iomanip>
#include <iostream>
#include <stdio.h>
#include <time.h>
#include <windows.h>
using namespace std;

int main () {
    // Shutdown
    cout << "Shutdown Complete!" << endl;  
ExitWindowsEx(EWX_POWEROFF, SHTDN_REASON_MAJOR_OTHER);
    //system("shutdown.exe -s -t 180");

    // Return Carriage
    return 0;
}

Thanks, Regards X
