crud - Insert/Delete/Update With ZK MDB Microsoft Access database File Not work -

-

i cant insert/update/delete access mdb file on file mdb saw readonly, reason cant use command it?

note: mdb file readonly note: software come zk fingerprint product code: 'b3-c/usb' "attendance management system" can work database.mdb, think can too.

i try this:

    try         cn.open()          commandtext = "insert userinfo(userid,name) values(2,'madaraz')"         sqldataadapter = new oledbdataadapter(commandtext, cn)         sqlcombuilder = new oledbcommand(commandtext, cn)         sqlcombuilder.executenonquery()      catch er mysqlexception         messagebox.show("error connecting database: " & er.message)             cn.dispose()     end try

when try run above code not error has nothing happens don know going on.

i hope expert can me thx guy in advance.

if database file read only, won't work. remove read attribute mdb file.

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.
