heyho, earlier today ran issues shell command in vba using excel2010 64bit. have fixed them hardcoded workaround, know why stopped working. here code snipped: dim mypath string dim myfolder string mypath = "d:\somefolder\" myfolder = "somesubfolder\" shell mypath & myfolder & "some.bat" until 2 weeks ago, consistently executing bat, stopped working. i have played around bit , checked other syntaxes using shell command , have yet make sense of it. whenever tried execute snipped "runtime error 5, invalid procedure call or argument" however, working 2 weeks ago, , haven't touched file. according ms documentation other arguments shell optional cannot problem. in end, instead of looping through directories, hardcoded paths in multiple commands this: shell """fullpath_to_.bat-files""" funny thing is, have multiple other vba scripts use old syntax described further up, meaning combining

i learning java , came accross code example. personbean mybean =(personbean)request.getattribute("mybean"); if(mybean=null) { mybean = new personbean(); request.setattribute("mybean",mybean); } here personbean mybean =(personbean)request.getattribute("mybean"); doing? mean in if statement there statement constructs object of class . purpose of first line here? can break down me ? this code gets "mybean" attribute request object (which contains incoming objects) , casts personbean. if not successful creates new personbean object name "mybean" , sets "mybean" object in request.

i'm working on native mobile app spans ios, android, , windowsphone platforms. google analytics being leveraged track screen views , custom events (mostly based on user taps). there typo in screen names sent google analytics on 1 of platforms. as hypothetical example, let's there registration page in app, , 2 of platforms sent "registration" screen name , other platform sent "registraton" screen name. typo corrected on client app, data in google analytics still shows incorrect brief time period. does know if possible correct simple typos this? if so, can point me in right direction? i've researched talks sending data google analytics rather correcting existing data in google analytics. it's not possible @ moment you're asking. i've felt pain myself before, , in case happens capitalization mistakes (e.g. sending both "click" , "click"). you can use filter target both variations, there's no way go , ch

this question has answer here: asking user input until give valid response 10 answers i need python keep asking raw_input if answer different 1 or 2. here example: print """what want me do? 1) press 1 if want ..... 2) press 2 if want .....""" while true: answer1 = raw_input(" => ") if (answer1 == 1): .... .... elif (answer1 == 2): .... .... elif (answer1 != 1 or 2) or answer1.isalpha(): print "i need 1 or 2" the problem python keeping asking raw_input if user enter 1 or 2. wrong? you should put break statement in if , elif block if answer 1 or 2 break out of while loop. example - if (answer1 == 1): .... .... break elif (answer1 == 2): .... .... break

i have managed output text using following line: fmt.fprintf(w, "<p>some text</p>") but literally output html tags. how output can safely included in html echo in php? fmt.fprintf() has no knowledge of html syntax: outputs raw data without escaping (it may formatting not escaping). you don't use correctly though: second parameter format string, should call rather this: fmt.fprintf(w, "%s", "<p>some text</p>") else if text contains format-specific special characters, not expected result. what want escape html code can safely included in html documents/pages. excellent support html/template package provides powerful template engine automatic escaping functionality being 1 feature. here's simple example how achieve want: w := os.stdout text := "<p>some text</p>" fmt.fprintf(w, "%s\n", text) tt := `{{.}}` t := template.must(template.new("test").parse(tt)

i play video file on local pc (path: " http://192.168.1.5:9000/assets/uploadedfiles/4.mp4 "). iphone , pc both in same network. following code works fine if play videos on iphone. otherwise displays black screen. self.objmovieplayercontroller = mpmovieplayercontroller(contenturl: url!) self.objmovieplayercontroller.moviesourcetype = mpmoviesourcetype.unknown self.objmovieplayercontroller.view.frame = self.videoview.bounds self.objmovieplayercontroller.scalingmode = mpmoviescalingmode.aspectfill self.objmovieplayercontroller.controlstyle = mpmoviecontrolstyle.embedded self.objmovieplayercontroller.contenturl = url! self.objmovieplayercontroller.shouldautoplay = true self.videoview.addsubview(self.objmovieplayercontroller.view) self.objmovieplayercontroller.preparetoplay() self.objmovieplayercontroller.play() i don't want download video file iphone. there way stream video file pc? thanks

i have existing <svg> , have defined groups <g> each group has own unique id. <g id="id_1"><text>...</text></g> <g id="id_2"><text>...</text></g> <g id="id_3"><text>...</text></g> <g id="id_4"><text>...</text></g> similarly have data formatted as data = { "id_2" : { "name" : value1, "description" : value2, ... }, "id_4" : { "name" : value1, "description" : value2, ... }, "id_9" : { "name" : value1, "description" : value2, ... } }; for each row. notice not id's match! i not wish replace <g> , instead bind each data row correct <g> tag id's match. default behavior of d3.select('g').data(d3.values(data)) not support bind index. how can this? i have sample code @ jsbin indexed data binding

i trying determine if database update performed in model successful, pass status of (successful or not successful) view can display div appropriately. far, it's worked long model update worked, not working when it's not. i'm using flashdata pass data through controller. my model: public function editticket($ticket) { $q = $this->db->where('ticketid', $ticket['ticketid']); $q = $this->db->update('tickets', $ticket); $results = $this->db->affected_rows(); return $results; } my controller: public function editexistingticket() { $this->load->model('tickets'); $date = date("y-m-d h:i:s"); $ticket = array( 'ticketid' => $this->input->post('ticketid'), 'category' => $this->input->post('category'), 'headline' => $this->input->post('headline'), 'description&

i'm trying use python mock library mock few methods zipfile module. example source want test: def zipstuff(listofpathtofiles): zipfile(fname, 'w') archive: each in listofpathtofiles: archive.write(each, strippedfname) return archive the "archive" above ignored normal execution, list of files during tests. example unittest code: emptylist=[] def mockwrite(fname): emptylist.append(fname) return mockzip.__enter__ = mock(return_value=emptylist) mockzip.__exit__ = mock(return_value=true) now, want mock archive.write instead of actual write call, replaced mockwrite function can list of files supposed zipped. i've tried: mockzip.write = mock(side_effect=mockwrite) but wasn't being called. debugging shows function calling mockzip. enter ().write. if try: mockzip.__enter__().write = mock(side_effect=mockwrite) python issues error 'list' has no attribute write (which correct). i'm new mock

i'm trying write simple string enum. i'd use standard enum need spaces in strings. i've tried prevent construction of other instances making constructor private. however, wanted implicit conversion make static declarations easier/neater (last line) public class stringenum { public static stringenum foo = "a foo"; public static stringenum bar = "a bar"; public static stringenum wibble = "a wibble"; public static stringenum crotchet = "a crotchet"; //etc... //implicit cast string public static implicit operator string(stringenum s) { return s.privatestring; } //private construction private string privatestring; private stringenum(string s) { this.privatestring = s; } private static implicit operator stringenum(string s) { return new stringenum(s); } } this implicit operator fails compile "the modifier private not valid item". make public other code can

i've been messing quite time now, can't work. i'm trying make ; a clickable table header, once clicked switches row order ascending descending , when clicked again. the attempts did far didn't loop, , got stuck after 1 click. just add link table header cell contains parameter, e.g. <tr><th> <a href="currentpage.php?order=<?php echo isset($_get['order'])?!$_get['order']:1; ?>"> name </a> </th></tr> what happens here? link added, containing order parameter set opposite of current order value(1/true or 0/false) or 1 default. in php script can decide how order table using order value: $isasc = isset($_get['order'])? (bool) $_get['order']: 1; now can use $isasc boolean: if ($isasc) { // sort data ascending } else { // sort data descending } or in query: $sql = "select * tabe order name ".($isasc?"asc":"desc")

we have ios (iphone , ipad) b2b application working specific name. want use same name in ios app or convert b2b application public one. we have been searching in internet , have seen 2 alternatives, have doubts both: 1-delete b2b application. if delete app, able use app name other app in other developer account? will current users' installations of app deleted mobiles automatically once delete app b2b? 2-convert b2b public. by making changes , uploading update itunes connect, can release app normal public, moving b2b?. firstly, if delete app, indeed able use app name again. secondly, current users installations won't delete. have manually delete apps devices, cannot delete them remotely. not 100% sure converting app b2b public, believe if upload itunes connect , select stores you'd sell in, pricing , submit review without problem release sale in select stores. hope helps, julian

i know browsers block cross domain cookies security reasons. i'm wondering if there way around it? have wp website , url shortener, url shortener tracking grabbing wp username cookie, if set. i've moved url shortener new short domain , tracking system has stopped grabbing username cookie. there way can reintroduce functionality? cross domain can allowed header access-control-allow-origin: * . but cannot share cookies through domains. an alternative solution this anwser : you this: centrilize cokies in single domain, let's cookiemaker.com when user makes request example.com redirect him cookimaker.com cookiemaker.com redirects him example.com information need of course, it's not completelly secure, , have create kind of internal protocol between apps that.

here code lecture note stack using array implementation. in specification: template <typename t> class stack { public: stack(); bool pop (t& stacktop); //there still other code private: int maxsize; int* arr; int _size; } in implementation: bool stack<t>::pop(t& stacktop){ if (isempty()){ return false; }else{ --_size; stacktop=arr[_size]; return true; } } and example of user program: stack<int> st; int k; st.push(1);st.push(2);st.push(3);//will add element 1 ,2, , 3. st.pop(k);cout<<"pop"<<k<<endl; //will pop last element 3 , print pop 3 i understand in pop implementation , update( reduce one) size of array. don't seem erase element! so, element still there, , reduce size top of array shifted? e.g. maximum size 100 in code push 1, 2 , 3. top on 3. , rest 97 elements still unassigned. pop (which last element 3). when pop, "move" top
