to make long story short have program uses qdomdocument class create xml file , uses save() function save text stream object. its qdomdocument somedoc; //create xml file, elements, etc. qfile io(filename); qtextstream out(&io); doc.save(out,4); io.close(); i want able show progress of save using qprogressdialog class, i'm having hard time figuring out. there way can incrementally check see if file through processing , update progress? suggestions? thanks. firstly, thought can find answer in qt source code, not simple, found easier solution, use tostring() method , write usual file. example: qstringlist = doc.tostring(4).split('\n');//4 intent int numfiles = all.size(); qprogressdialog *progress = new qprogressdialog("copying files...", "abort copy", 0, numfiles, this); progress->setwindowmodality(qt::windowmodal); qfile file("path"); file.open(qiodevice::writeonly); progress->show(); qtextstream stream(&

i have file try read contacts simple contactbook using structure. typedef struct contact{ char name[80]; char surname[80]; char cellnumber[20]; float length; int contactid; }contact; i use function , call reads 200 times ( const int maxcontact = 200; ). for(i2=0;i2<maxcontact;i2++) person[i2]=load(i2); this function given id (the variabile i ), returns contact has same i: contact load(int i){ struct contact person; file *data; data=fopen("data.bin","rb"); do{ fread(&person,sizeof(contact),1,data); }while(person.contactid!=i); fclose(data); return person; } the problem kind of code is, when there no 200 contacts, function not return contact because contact id can't found. i had solutions in mind rather complex , wanted know if done better. make installer creates files real installer , create 200 undeclared contacts variabiles equal null. check if program being ran first time

this rust tutorial explains fold() mechanism well, , example code: let sum = (1..4).fold(0, |sum, x| sum + x); works expected. i'd run on vector, based on example, first wrote this: let sum: u32 = vec![1,2,3,4,5,6].iter().fold(0, |sum, val| sum += val); which throwed error: error: binary assignment operation `+=` cannot applied types `_` , `&u32` [e0368] let sum = ratings.values().fold(0, |sum, val| sum += val); ^~~~~~~~~~ i guessed might reference-related error reason, changed fold(0, |sum, &val| sum += val) , resulted with error: mismatched types: expected `u32`, found `()` hm, maybe something's wrong closure? using {sum += x; sum } , got binary assignment operation `+=` cannot applied types `_` , `&u32` again. after further trials , errors, adding mut sum worked: let sum = vec![1,2,3,4,5,6].iter().fold(0, |mut sum, &x| {sum += x; sum}); could explain reason why fold() vector

is possible hide first x character of h4 element via css? for example: <h4>data: random data.</h4> "data: " shall not shown. i tried overflow , moving div contains h4, works, isn't solution me. maybe there's command don't know helps. know javascript , strreplace work well, i'm looking pure css solution. sadly, css can't calculate width of strings , has no access textual content... if using monospace fonts, you'd able calculate width manually, based on font size, still bad solution. negative margins, indents, etc. unreliable have no idea how fonts rendered, meaning break , ugly in different browsers, under different zoom levels, etc... bottom line: css alone can't it

in javascript can do: function foo() { ... return { attr1 : ... , attr2 : ..., }; } but equivalent in java? because want return custom json object controller after ajax call , want create new bean. as java dictates, should create new class , convert json. also, can use map<string,object> accomplish same thing. generate following json: { "attr1":1, "attr2":2 } you can use following code: map<string,object> map = new hashmap<>(3); map.put("attr1", 1); map.put("attr2", 2); and convert json. p.s.: hashmap in java causes heap increase , unnecessary garbage, specified enough size keep 2 elements.

i'm trying post_name attribute wp_query($args) function in wordpress. if i'm using var_dump($wp_query); shows me post_name attribute not empty or null. title of post. but if i'm trying echo using echo $wp_query->post_name; returns empty string. this how define $wp_query : $args = array('posts_per_page' => 5, 'tag' => 'general'); $wp_query = new wp_query( $args ); there posts has tag "general" cannot reason. can please explain behaviour or tell me i'm doing wrong? this because $wp_query isn't single post, posts match query args. means have loop on posts in query result in way. instance, can this: $args = array('posts_per_page' => 5, 'tag' => 'general'); $wp_query = new wp_query( $args ); // posts query $posts = $wp_query->get_posts(); // loop through posts foreach( $posts $post ) { echo $post->post_name; }

i trying understand how compiler views following print statements. simple yet bit intriguing. this prints added value. convincing enough. system.out.println(1+2); //output: 3 the output following looks convincing well: system.out.println(1+2+"3");//output: 33 my question (based on behavior above) here. system.out.println("1"+2+3);//should 15 right? no. 123. i tried few other such statements along same lines. able see 1 2 clear behaviors. if integers @ front, without quotes, added , subsequent integers appended suffix added values front. if statement starts string, under quotes, other subsequent elements appended suffix. is somewhere in java api docs? or obvious string or add operator behavior not seeing. of valuable insights appreciated. here code snippet: public static void main(string[] args) { system.out.println(1+2); system.out.println(1+2+"3"); system.out.println("1"+2+3); system.out.

i made oauth2 server, , want make c client using symfony2 connect (when click login, i'm redirected on site oauth2 server, login, i'm redirected client token). i followed this: http://symfony.com/doc/current/cookbook/security/api_key_authentication.html the problem whem retrieve apikey. if decide use implicit grant oauth2, token sent that: example.com/#token can't retrieve query->get. if send code it's fine, when tried curl server somehow broke (yeah, not specific error, still looking it) so wondering, proper way of doing it? also, when write specific url, why need one, if can check everywhere? thanks :) you can token in php : for known url if have url hash, part after # called fragment. $url=parse_url($yoururl); echo $url["fragment"]; if don't have url in backend, need javascript magic : var token = window.location.hash; then send backend. maybe there other more symfonyc way properly, never used oauth2 yet.. :d
