i newbie , have basic doubt relationship between object creation , constructors. program- 1 #include<iostream> using namespace std; class xxx{ private: int x; public: xxx(){cout<<"constructer called"<<endl;} }; int main(int argc, char *argv[]) { xxx x1; //constructor called return 0; } output- constructor called program- 2 #include<iostream> using namespace std; class xxx{ private: int x; public: xxx(){cout<<"constructer called"<<endl;} }; int main(int argc, char *argv[]) { xxx x1(); //constructor xxx() not called. return 0; } output- blank information helpfule xxx x1; creates object of class xxx , therefore, calls default constructor of class xxx . xxx x1(); declares function returns object of class xxx , function name x1 , takes no parameter. not instantiation of class xxx , therefore, there no constructor being called.

is there way determine if response httpwebrequest in c# contains binary data vs. text? or there class or function should using this? here's sample code. i'd know before reading streamreader if content not text. httpwebrequest request = (httpwebrequest)webrequest.create("http://www.someurl.com"); request.method = webrequestmethods.http.get; using (webresponse response = request.getresponse()) { // check somewhere in here if response binary data , ignore using (streamreader reader = new streamreader(response.getresponsestream())) { string responsedetails = reader.readtoend().trim(); } } in general , web sites tell in content-type header kind of data they're returning. can determine getting contenttype property response. but sites have been known lie. or not anything. i've seen both. if there no content-type header or don't want trust it, way can tell kind of data there, reading it. but then, if don't trus

like in this question , want add .error on form field's parent .control-group when scope.$invalid true. however, hardcoding form name in ng-class="{ error: formname.fieldmodel.$invalid }" means can't reuse in different forms, plus i'd rather not repeat declaration everywhere. i figured directive looks work: <div class="control-group" error-on="model1, model2"> <input ng-model="model1"> <input ng-model="model2"> </div> so when either model1 or model2 not valid, .control-group gets .error added. my attempt here . possible access models directive, given model names? if there's better approach, i'd love hear too. i don't think writing custom directive necessery use-case ng-form directive created situations those. directive's documentation: it useful nest forms, example if validity of sub-group of controls needs determined. taking code exampl

i have array string[] arr={"a","b","c","d","e","f","a","d","m","e"}; i want random 4 different numbers array. how must do? list<string> shuffled = collections.shuffle(arrays.aslist(arr)); list<string> fourrandoms = shuffled.sublist(0, 4); or, if want leave array untouched: list<string> shuffled = collections.shuffle(new arraylist<string>(arrays.aslist(arr))); list<string> fourrandoms = shuffled.sublist(0, 4); edit: remove duplicates array, use set: set<string> uniquevalues = new hashset<string>(arrays.aslist(arr)); list<string> shuffled = collections.shuffle(new arraylist<string>(uniquevalues)); list<string> fourrandoms = shuffled.sublist(0, 4); learn standard java collections, , avoid using arrays completely. should use set beginning if duplicates not allowed.

am trying plot line chart in iphone app using core plot. unable draw graph small size in iphone screen. have set in storyboard (actually want smaller this, since want fit 2 graphs in screen, minimum size started showing plots, though showing 2 plot out of 5) and getting displayed in phone i removed padding graph & tried, in vain. in above scenario, have set padding to: self.graph.plotareaframe.paddingbottom = 2.0; self.graph.plotareaframe.paddingtop = 2.0; self.graph.plotareaframe.paddingleft = 2.0; self.graph.plotareaframe.paddingright = 2.0; and have set graph hosting view's bounds bounds of view in storyboard. kindly help. think should possible draw small graph, not sure why not allowing it. setting wrong? i increased yrange (plotspace.yrange) , worked! shows 5 data plots.

trying better grapple on how public/private keys work. understand sender may add digital signature document using his/her private key obtain hash of document, not understand how public key can used verify signature. understanding public keys encrypt, private keys decrypt... can me understand? your understanding of "public keys encrypt, private keys decrypt" correct... data/message encryption. digital signatures, reverse. digital signature, trying prove document signed came you. that, need use have: private key. a digital signature in simplest description hash (sha1, md5, etc.) of data (file, message, etc.) subsequently encrypted signer's private key. since signer has (or should have) trust comes from. has (or should have) access signer's public key. so, validate digital signature, recipient (1) calculates hash of same data (file, message, etc.), (2) decrypts digital signature using sender's public key, , (3) compares 2 hash values. if match

i have been reading functionals github . 1 suggestion in page use call_function if 1 working list of functions. here code page: call_fun <- function(f, ...) f(...) f <- list(sum, mean, median, sd) lapply(f, call_fun, x = runif(1e3)) the output posted as: # [[1]] # [1] 498 # # [[2]] # [1] 0.498 # # [[3]] # [1] 0.49 # # [[4]] # [1] 0.29 however, not able replicate above results. got error: error in fun(x[[4l]], ...) : not find function "f" am missing here? you have redefined function sd : sd = 2 call_fun <- function(f, ...) f(...) f <- list(sum, mean, median, sd) lapply(f, call_fun, x = runif(1e3)) #error in fun(x[[4l]], ...) : not find function "f" restart session or rm(sd) .

i using below jquery code add , remove class has display:none property , add class has display:block 3 different divs positioned relatively. have side navigation has 3 links that, when clicked, want displays different divs on page, 1 fading out , other fading in. $(document).ready(function () { $('#what-we-do, #location').hide(); $('#who-we-are').show(); }); $(function () { $("#show-main-who").mousedown(function () { $('#what-we-do, #location').fadeout('fast', function () { $(this).addclass('hide-info'); $(this).removeclass('show-info'); }); }); $('#show-main-who').mouseup(function () { $('#who-we-are').fadein('fast', function () { $(this).removeclass('hide-info'); $(this).addclass('show-info'); }); }); }); $(function () { $("#show-main-what").mousedown(function () {

i have written c# windows application form runs on client machine , connects sql server on machine.while building connection in c# have used dlls like 1)microsoft.sqlserver.management.smo. 2)microsoft.sqlserver.management.connectioninfo 3)microsoft.sqlserver.management.sdk.sfc the client machine on aplication built having sql server installed on it. importing , accessing dlls not problem. however on other client machine on going run c# windows application not having sql server installed on it. so cause problem.will connection fail on client machine due absence of sql server. if yes, way around solve problem without installing sql server on client machine. ps: asking beforehand avoid last minute hassle on day of installation. the pieces needed connect sql server built .net framework. long used when coding client piece can connect sql database without mssql installed on client. using system.data; using system.data.sqlclient; sqlclient ps: asking before

edit : quick responses guys - ended switching mysql_fetch_assoc() , using do...while , go. i using same process create , populate tables - works fine except first row skipped in every table . use pair of eyes can't seem pinpoint issue. in advance. $query = "select * members"; $results = mysql_query($query); $row = mysql_fetch_array($results); //echo <table> start , headings; while ($row = mysql_fetch_array($results)) { echo "<tr><td>".$row['last name']."</td>"; echo "<td>".$row['first name']."</td>"; echo "<td>".$row['middle name']."</td>"; echo "<td>".$row['sfx']."</td>"; echo "<td>".$row['prf']."</td>"; echo "<td>".$row['spouse/so']."</td>"; echo "<td>&
