How to use an external dll file in a managed visual c++ project generated through firebreath -

-

i have use functions of external dll file in firebreath project. project managed c++ project. want know how refer or include external file in project.i not getting add reference option in visual studio 2010 (because managed c++ project). please tell me way this..

assuming know names of functions want call within dll, mechanism have use following:

// these examples of functions --> change return values , params needed typedef char (winapi *dll_func1) (ushort, ushort); typedef char (winapi *dll_func2) (ushort, uchar*, uchar*, ushort, uchar*, ushort*, uchar*); typedef char (winapi *dll_func3) (ushort);  // load library hmodule hdll = loadlibrary( l"\\path\\to\\your.dll" );  // check if dll loaded  if (hdll == null) {     // error      return; }  // assign functions dll_func1 func1 = (dll_func1) getprocaddress( hdll, "name_of_func1" ); dll_func2 func2 = (dll_func2) getprocaddress( hdll, "name_of_func2" ); dll_func3 func3 = (dll_func3) getprocaddress( hdll, "name_of_func3" );  // use functions --> here func1 example if( func1( 1, 2 ) != ok ) { // or whatever return value     // error     freelibrary( hdll );      return; }  // --> go on working dll functions  // not forget call @ end freelibrary( hdll );

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.
