Execute a Shell command silently and get the Output
Hello everyone,
I was looking for a way to execute a shell command (e.g. "ping localhost") without the user seeing a command shell(Win XP)
and recieve its output. Any ideas on that?
Thank you in advance,
Lord.

You can use _popen to open the command as a FILE *, and then use the standard fgets/fscanf/etc. functions to read the result, then use _pclose to close the stream. Hope this helps.
Call ShellExecute() with the SW_HIDE flag. Or call CreateProcess() with the DETACHED_PROCESS flag.

This code:
#include <stdio.h>
void main(void) {
FILE* cons;
char s[999];
cons = _popen("ping localhost","r");
while(fscanf(cons,"%s",s))
printf("%s",s);
_pclose(cons);
scanf("%s",s);
}
Provides me this(excuse my german Windows)
