php - Block system commands in a C program -

-

i compiling , executing c program uses php system command on windows xp server.

if c program contains system command system("shutdown -a") or system command, turns system down.

i want these kinds of commands denied. how show "permission denied" output when program tries run system command?

here code.

php script contains-

system(gcc code.c -o out);    system(out.exe);

if c program contains-

int main()     {      system("shutdown -r");   }

is there way block commands being run?

windows runas command

you might able use windows runas command run command specific user. , in user's profile, set list of white listed commands. https://superuser.com/questions/42537/is-there-any-sudo-command-for-windows

roll own command white list

create list of commands in php or c allowed run through c program, , if command isn't on approved list, denied. or of live dangerously, create black list, , define bunch of things don't want run.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
