( plugin able read mysettings in override settings area ) the way communicate mysettings plugin via window object question : what correct way configure plugin can have many(!) settings via js file. as don't have code example work i'll give generalized solutions. collect settings object(s) in array , iterate on them within override settings area. expose plugin via window , directly append settings there. example 1 js //file 1.js window.settings = window.settings || []; window.settings.push({a:'11'}); //file2.js window.settings = window.settings || []; windo...

i've visited few sites on iphone/ipad have prompted me install native app first time i've visited site. there standard script somewhere people use or should create own? must have been thousands of times before despite endless googling can't find 'stock' script can use. ideally should use cookies user doesn't prompted more once month or so. apple have got built in way of doing relatively unobtrusively, adds "smart app banner" @ top of browser if app isn't installed: to add smart app banner website, include following meta tag in head of each page you'd banner appear: <meta name="apple-itunes-app" content="app-id=myappstoreid"> for more options, please see full documentation on apple's site: http://developer.apple.com/library/ios/#documentation/appleapplications/reference/safariwebcontent/promotingappswithappbanners/promotingappswithappbanners.html this adds nice looking banner top of page, ca...

this question has answer here: extracting c / c++ function prototypes 7 answers is there kind of tool shows function prototypes of given source file? know doxygen doing such thing, find simple linux command such as $ filter-function-prototypes main.c 1: print_hello() 2: main() where main.c given as #include <stdio.h> void print_hello() { printf("hello, world\n"); } int main() { print_hello(); } apparently ctags can that! ctags -x --c-kinds=f main.c there's stuff in output can handled sed or awk . or cut ctags -x --c-kinds=f cards.c | cut -c 51-

i have following situation, porting piece of app using openssl aes encryption, have compile, linker fails. situation following: 1. wrote jni wrapper : private native string cipherstring(string plaindata, int datasize, string password, int passsize); private native string decipherstring(string ciphereddata, int datasize, string password, int passsize); next have c++ file call has proper jni sintax translates jstring char * , other needed transformations, , makes call cpp file imports openssl headers (present , accounted for) , calls openssl methods ciphering , deciphering. so when call ndk-build, builds thumbs, compiler compiles them correctly. next needed port openssl android, , used openssl android works char simple ndk-build (in root of project, ofcourse) , builds libssl.so , libcrypto.so so need connect two.. find challenge connect build scripts, 1 ndk-build compiles , linkes (i appreciate simple example project if has time it) so copied compiled libssl , libcrypto...

i evaluating possibilities create mobile hybrid apps gwt , apache cordova / phonegap. build small prototype mgwt , liked it, research few other possibilities before starting project. therefore took @ vaadin , addon touchkit. i have following questions: is possible use vaadin touchkit addon in client-side application not need permanent server connection? in mobile chapter of documentation example shown server-side application, far understand , therefore need server connection each ui event. please correct me if i'm wrong, have no experience vaadin. is there difference between "normal" gwt app , client-side vaadin app? does has advantages use vaadin touchkit instead of mgwt? in general vaadin touchkit comparable mgwt , if yes main differences? you can build vaadin touchkit applications work offline.

i have image , mask image image make shape. i want change view background color of masked image. i using [uicolor colorwithpatternimage:maskedimage]; but not working. please suggest me how merge or create masked 2 images in 1 image colorwithpatternimage work. uiimage *originalimage = [uiimage imagenamed:@"original.png"]; //my background image uiimage *maskedimage = [uiimage imagenamed:@"maskedimage.png"]; //my masked image cgsize newsize = cgsizemake(width, height); uigraphicsbeginimagecontext( newsize ); [originalimage drawinrect:cgrectmake(0,0,newsize.width,newsize.height)]; [maskedimage drawinrect:cgrectmake(0,0,newsize.width,newsize.height) blendmode:kcgblendmodenormal alpha:0.6]; uiimage *newmaskedbackgroundimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext(); then use newmaskedbackgroundimage, ex.

my problem "failbit" set directly when trying read textfile. strange thing, me @ least, if build program , run it, works. when try debug failbit sets. the actual error message this: "unhandled exception @ 0x7740c41f in steg1_1a.exe: microsoft c++ exception: std::ios_base::failure @ memory location 0x003bf8e4.." and text console program this: "ios_base::failbit set". the question is, how fix failbit doesn't "crash program" when debugging? here function: void selectedmenuchoice(int choice) { int index = 0, initvalue = 0; const int filenumbercount = 24; double numfromfile = 0.0, sum = 0.0, average = 0.0, max = 0.0, min = 0.0; switch (choice) { // "display temperature values" case 1: cout << "\ndisplaying latest 24 temperature values:\n\n"; break; // "view maximum , minimum temperatures" case 2: cout << "\ncalculating maximum , minimum tem...

i use approach obtain correct relative uri (independent of deployment situation). razor code (asp.net mvc 3): @section javascript { <script type="text/javascript"> var _geturl = "@url.content("~/bla/di/bla")"; </script> } separate js file: $.ajax({ url: _geturl, do reckon there better approach? personally prefer using html5 data-* attributes or including url part of dom element unobtrusively ajaxify. the thing never write $.ajax calls flying around that. write them correspond dom events. example clicking of anchor. in case it's trivial, use html helper generate anchor: @html.actionlink("click me", "someaction", "somecontroller", new { id = "123" }, new { @class = "link" }) and then: $('.link').click(function() { $.ajax({ url: this.href, type: 'get', success: function(result) { ... ...

i'm working on program problem has natural logarithmic scale. so far i'm using base 2, nice implementation of unsigned int log2(uint64_t) (in c/c++), found here . however, found base 2 problem: need use fractional bases, e.g. 3/2. is aware of implementation kind of operation? my current solution round(log(x)/log(base)) round returns integer, hopping, @ least, avoid 2 evaluations of log. log(base) constant, evaluate once , take reciprocal (to turn onto multiply rather expensive divide). const float k = 1.0f / log(base); // init constant once y = round(log(x) * k); // each evaluation requires 1 log, // 1 multiply , 1 round

i'm new c , learning processes. i'm little confused code below doing, it's taken wikipedia i've seen in several books , unsure why, example, pid_t pid; pid = fork(); . reading seem suggest child process returns pid of 0 , however, thought original parent process maintain pid of 0 after seeing tree root pid 0 . what does, example, pid = fork(); parent? doesn't same thing child? , doesn't pid = fork(); put loop each child? basically, explain each step me if were, say, five? maybe younger? thanks! #include <stdio.h> /* printf, stderr, fprintf */ #include <sys/types.h> /* pid_t */ #include <unistd.h> /* _exit, fork */ #include <stdlib.h> /* exit */ #include <errno.h> /* errno */ int main(void) { pid_t pid; /* output both child , parent process * written standard output, * both run @ same time. */ pid = fork(); if (pid == -1) { /* error: * when fork() returns -1, error ha...
