c# - Repeat a listbox that opens files -

-

hello want listbox playlist repeat after last file played. how reset index repeats start of listbox? shownextimage handles media 1 one show on mediaelement. dispatchertimer shows images 20 seconds , continues.

this got.

    dictionary<string, string> listbox1dict = new dictionary<string, string>();     public static list<string> images = new list<string> { ".jpg", ".jpe", ".bmp", ".gif", ".png" }; // bildtyper som stöds     public static list<string> movies = new list<string> { ".wmv", ".wav", ".swf", ".mp4", ".mpg", ".avi" };     list<string> paths = new list<string>();     dispatchertimer dispatchertimer = new dispatchertimer();     dispatchertimer nextimagetimer = new dispatchertimer();     int x = 20;     private int currentsongindex = -1;     private void shownextimage()     {         if (currentsongindex == -1)         {             currentsongindex = listbox1.selectedindex;         }         currentsongindex++;          var selected = listbox1.items[currentsongindex];         string s = selected.tostring();         if (listbox1dict.containskey(s))         {              if (images.contains(system.io.path.getextension(s).toupperinvariant()))             {                  if (currentsongindex < listbox1.items.count)                 {                     mediaelement1.source = new uri(listbox1dict[s]);                  }             }             else if (movies.contains(system.io.path.getextension(s).toupperinvariant()))             {                 if (currentsongindex < listbox1.items.count)                 {                     dispatchertimer.stop();                     mediaelement1.source = new uri(listbox1dict[s]);                 }             }         }     }

the timers:

    private void dispatchertimer_tick(object sender, eventargs e)     {             shownextimage();     }     private void dispatch()     {         dispatchertimer.tick += new eventhandler(dispatchertimer_tick);         dispatchertimer.interval = new timespan(0, 0, 0, x);     }

maybe want:

<stackpanel>     <listbox selectedindex="{binding elementname=index, path=value}">         <listboxitem>first</listboxitem>         <listboxitem>second</listboxitem>         <listboxitem>third</listboxitem>     </listbox>     <slider x:name="index" minimum="0" maximum="2" value="2" tickfrequency="1" issnaptotickenabled="true" tickplacement="bottomright"/> </stackpanel>

in sample selected index of listbox bound value of slider. slider should replaced indexproperty in viewmodel notifies when changed. index prop should increment after finishing playing song , set 0 if song last. think should handled in vm.

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.
