how link file contains space? possible? have javascript document , have dozens of images contain spaces hoping able still link them. %20 escaped value blank space. use in hyperlink, , you'll file want :) in case test in browser: modern browsers (chrome sure) not visually change space %20 anymore in address bar, still escape characters before making web request. edit generally speaking, you'd html encode strings via accessible method, rather manually escaping needed characters. the following question has elegant solution. if use element not visible user (or not part of dom, case linked answer), won't know.

i can't define object other classes under top class example : class b; class { public: a(){ cout << "a\n"; } ~a(){ cout << "~a\n"; } private: b ob; }; class b { public: b(){ cout << "b\n"; } ~b(){ cout << "~b\n"; } ob; }; int main() { b r; system("pause"); } the problem can't make object in class if write (class b;) above it your problem solved passing b object pointer a constructor. if change b class contain pointer a , recursion solved. is, creating infinite loop, creating object b contains object a , contains object b , , on. class b { public: b(a* _ob) : ob(_ob) { cout << "b\n"; } ~b(){ cout << "~b\n"; } a* ob; }; int main() { _a; b r(_a); system("pause"); }

i have db this: id group drink 1 yes 2 no 3 na 4 b no 5 b no 6 b yes and measure how many people of group drinks , how many people in group b drinks. i using length() , function returns 3 ( na being considered = yes). how can fix it? table() 1 option: db <- read.table(text = "id group drink 1 yes 2 no 3 na 4 b no 5 b no 6 b yes", header = true) with(db, table(drink)) with(db, table(group, drink)) > with(db, table(drink)) drink no yes 3 2 > with(db, table(group, drink)) drink group no yes 1 1 b 2 1 including na class achieved usena argument: with(db, table(drink, usena = "ifany")) > with(db, table(drink, usena = "ifany")) drink no yes <na> 3 2 1 you can of course store objects returned table() , access them other matrix/array: tab <- with(db, table(drink, usena = "ifany...

as far understand raii refers acquire resources in ctor , release them in dtor. ctor acquires resources , can fail, resulting in exception. dtor releases resources , can fail, exception dtors foobar no exception. class { a() throw(ex) { // acquire resources } ~a() throw() { // release resources } } so if user of class should made aware of error happening in a´s uninitialisation can outsource uninitialisation function throws, called dtor swallows exceptions: class { a() throw(ex) { // acquire resources } ~a() throw() { try {release(); } catch(...) {} } void release() throw(ex) { // release resources } } that way user can call exit() if wants feedback release-error or ignore letting dtor it´s job when goes out of scope (e.g. other exception occurs used). to prevent multiple executions of exit() (first explicitly user, later indirect dtor) have add init-status: class { bool init; a() throw(ex) { init = true; // acquire resources } ~a() throw() { try {rel...

among elements of set, want list 3-combinations of set. there way it? if list; for(int i=0; i<list.size()-2; i++) for(int j=i+1; j<list.size()-1; j++) for(int k=j+1; k<list.size(); k++) system.out.println(list.get(i) + " " + list.get(j) + " " + list.get(k)); but how set without converting list? converting list , using logic code first choice. if want without converting list, can iterators, this: set<string> set = ...; (string : set) { boolean bgo = false; (string b : set) { if (bgo) { boolean cgo = false; (string c : set) { if (cgo) { system.out.println(a + " " + b + " " + c); } else if (b.equals(c)) { cgo = true; } } } else if (a.equals(b)) { bgo = true; } } } the logic above freely iterates set in outer loop. when ...

i'm new mfc,and want data in dialog,but doesn't work, ctestdoc* pdoc=getdocument(); pdoc->get(...); i google , find getdocument() used in cview. try , works: cmainframe *pmain=(cmainframe *)afxgetapp()->m_pmainwnd; ctestview *pview=(ctestview *)pmain->getactiveview(); m_name=pview->v_name; but don't think it's solution,so want know there functions solve this?thank you. you didn't dialog may desirable pass data dialog, , not have dialog access document data directly. helps keep dialog more isolated , more usable in other programs. i @ command dialog displayed. in view? if so, can pass document data needed dialog. if not, code posted may still make sense. either way, that's should locate desired document information, , pass dialog. i avoid making dialog directly aware of document if it's not necessary.

i've got embedded derby database in java application, , have multiple table's (that created , deleted, nothing set in stone). wanted able return list of names of tables in database have display list in application information them. easiest way so? don't need code method or methods. i'm terrible google-fu user. currently code works grabbing resultset specific table name entered, it's testing purposes , need able display full list of tables have. edit: current workaround different posted. have table holds table names created , updates when 1 created/deleted. not best approach works me right now. databasemetadata metadata = connection.getmetadata(); resultset resultset = metadata.gettables(null, "schenaname", "%" ,new string[] {"table"} ); while (resultset.next()) { system.out.println(resultset.getstring(3)); } adding new answer: connection connection = getdbconnection(); databasemetadata dbmetadata =...

hopefully question title makes sense. just wondering if possible data record in mysql, remove commas , print each item individually? i have column called tags, , example in 1 of records tags "rock,bass,alternative" what want remove commas , print html code <a href ="/tag name"> before , </a> after each individual tag. so far code : $id = $_get['id']; $station = mysql_query ( "select * `stations` `id` = '$id'" ); $sta = mysql_fetch_object ( $station ); <? echo "$sta->tags";?> explode on , , giving array, print each item , concatenate string encapsulstaion. $tags = explode(',', $sta->tags); foreach($tags $tag): echo "$tag"; endforeach;

i making sumo bot project using arduino. have no experience arduino code, have java experience. said bot has edge detector prevent falling off, l298 driver, , forth. lack of experience, don't know how arduino's code works methods , etc. said, main question how executing methods delays? getting stuck in methods no return? not entering? executing ending later? seems run motors forward without switch on or off. have checked wiring. ( apologize poor questioning- stackedoverflow virgin). int motor_forward = 10; int motor_reverse = 9; int motor2_forward = 13; int motor2_reverse = 12; int edgedec1 = 7; //int edgedec2 = 6; //the setup routine runs once when press reset; void setup(){ //initialize digital pin output. pinmode(motor_forward, output); pinmode(motor_reverse,output); pinmode(motor2_forward,output); pinmode(motor2_reverse,output); pinmode(edgedec1,input); } //the loop routine runs on , on again forever void loop(){ int indicator = random(2); delay(50...

i want prevent installation of ios app in jail broken devices. there checks can done during installation identitfy if device jail broken ? there way stop installation if device jail broken? generally, break down 2 questions: 1) detection of jailbreak device. there plenty of different methods. none of them 100% guaranteed work. @ question: how detect ios app running on jailbroken phone? 2) taking actions on jailbroken device as @paulw11 mentioned, can't stop installation , can't uninstall. the common way exit application (don't provide useful functionality user). however, if application have high value, protection can removed reverse engineer application. generally speaking, there no bulletproof protection, can make enough, won't worthwhile breaking it.

my issue in make file want create directory object code before building , cannot find way whithout having impact output of make. also, want in 1 place , not each , every object file. i have tried this: build: setup exe.i686 setup: mkdir -p obj exe.i686: $(objs) @echo 'building target: $@' @echo 'invoking: gcc c++ linker' ${gcc_location}/linux/i686/bin/i686-pc-linux-gnu-g++ $(objs) -o "exe.i686" -l... @echo 'finished building target: $@' @echo ' ' where objs object code. if don't run setup first , there no ./obj directory present build fail because of missing directory when trying build object code. just clear, here example of how 1 object file built: ./obj/cell.o: ${cell_root}/main/cell/cell/src/cell.cc @echo 'building file: $<' @echo 'invoking: gcc c++ compiler' $(gcc_c++_build) -mf"$(@:%.o=%.d)" -mt"$(@:%.o=%.d)" -o "$@" "$<"...
