c# - How to capture logoff cancelled in windows server 2003 -

-

i'm working on terminal services based system running on windows 2003. consists of desktop replacement application user starts programs. has logoff-button. when user logs off 2 things must happen. first off, logged out of windows. stored procedure called cleaning users database state. works fine, 1 situation, , when user cancels logoff event. typical scenario: 1- user logs in, starts ms word, edits document, not save. 2 - user presses logoff button. 3- ms word reacts asking user save changes. 4 - user presses cancel.

at point desktop application might have called stored procedure cleaning database state. how catch behaviour in desktop application? there message saying end session operation cancelled?

does question make sense @ all?

oh, of applications written in delphi 7, work in c, c++ , c# well, answers in languages appreciated well.

if user state logic inside shell replacement think of application redesign: decouple custom shell session management.

for example: move user state logic in service. within service register rds notifications: wts_session_logon/wts_session_logoff.

i think wts_session_logoff sent only when actual logoff occurs i.e. if user clicks cancel button in word windows know user hasn't logged off , os not send wts_session_logoff (this untested, sounds logical).

this way don't deal wm_endsession/wm_queryendsession stuff.

recently wrote guidance on rds notifications topic.

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.
