i had function below working convert seconds hh:mm:ss in ssrs. needs work seconds in excess of 86400 i.e. total time greater 24 hours. function below returning strange values 00:00:.2 or 00:00:75 public function convertsecondstohourminsec(byval inttotalseconds) string dim hours string =int(inttotalseconds/3600) if len(hours) < 2 hours = right(("0" & hours), 2) end if dim mins string = right("0" & int((inttotalseconds mod 3600)/60), 2) dim secs string = right("0" & ((inttotalseconds mod 3600) mod 60), 2) convertsecondstohourminsec = hours & ":" & mins & ":" & secs end function passing function value of 227.16666 gives 00:03:67, example. any idea how can fix function give hh:mm:ss? realized wasn't converting seconds int on bottom. works now.

so know how convert string utf8 format for character in strings.utf8 { // example converted 65 var utf8value = character } i read guide can't find how convert unicode code point represented integer string. example: converting 65 a. tried use "\u"+utf8value still failed. is there way this? if @ enum definition character can see following initializer: init(_ scalar: unicodescalar) if @ struct unicodescalar, see initializer: init(_ v: uint32) we can put them together, , whole character character(unicodescalar(65)) and if want in string, it's initializer away... 1> string(character(unicodescalar(65))) $r1: string = "a" or (although can't figure out why 1 works) can do string(unicodescalar(65))

i trying pull out entities text, , have simple mechanism (until deploy nlp solution) avoid negation. e.g: i'd find patient has history of cynicisimitis but avoid no history of cynicisimitis and avoid family history of cynicisimitis to end using multiple lookbehinds make regex this: ((?<!(?i)no.{1,25}|denies.{1,35}|family.{1,35}|father.{1,10}|mother.{1,10})(?-i)${stringtomatch}) i tried adding \b negative lookbehind, thinking reduce entry points processor have, made performance worse. problem - appears performing badly. what can do: using \b avoid false matches (in particular word "no") removing useless (?-i) (an inline modifier applies group is.) factorizing when possible reduce performance impact of .{m,n} you obtain: (?<!(?i)\b(?:no\b.{1,25}|(?:denies|family)\b.{1,35}|(?:fa|mo)ther\b.{1,10})\b)history of cynicisimitis\b what can try: using lazy quantifiers instead of greedy quantifiers: \bno\b.{1,25}? p

this super simple maths can't working. trying add 1 int every 100 stored in dynamic int. for example if myint = 350 intnumber = 3 . or myint = 570 intnumber = 5 to clarify don't want remainder hence why don't want x/100 i know similar obvious not: for (int = 0; < 100; i++) { } this trivial: int myint = 350; int intnumber = myint / 100; // 3

in php, i'm saving date record string in order make conditions "more than", "less than"; know how decode it. want this: the moment record being saved 2014, 08/06 1:30 in 24-hours format, integer should 201408060130 , of course use date() function. but when comes decoding show 2014, 08/06 1:30 or format 08/06 2014, 1:30 stuck thinking on solution this. i thought like: $date = date('ydmhm'); //saving 201408060130 $this->savetodatabase($save, $mytable); $datedecoded = $this->getfromdatabase($mytable, $id, $thedateinteger); $result = date::getformat($datedecoded, 'ydmhm'); //decode date format echo $result->date('y d/m, h:m'); //show 2014 08/06, 1:30 this simple & works. use strtotime : $test_value = '201408060130'; echo date('y d/m, h:i', strtotime($test_value)); the output is: 2014 06/08, 01:30

the title pretty it. if standard c++ string utf-8 characters has no 0 bytes scanning terminate @ end of string defined it's size? conversely, if string has 0 byte scanning stop @ byte, or continue full length of string? i've @ re2.h file , not seem address issue. a std::string containing utf-8 characters can´t have 0-bytes part of text (only termination), because utf-8 doesn´t allow 0´s anywhere. and given you´re using c++11-compliant, terminating 0 guaranteed (doesn´t matter if use data() or c_str() . , data original data, so...). see http://en.cppreference.com/w/cpp/string/basic_string/data or standard (21.4.7.1/1 etc.). => processing of string stop @ 0

i'm developing application iterates on dom elements, , performs ajax request each 1 of elements. problem cannot access each dom element inside callback function. $('.class').each(function() { $.getjson(url, function(data) { $(this).attr('id', data.id); // $(this) not accessible }); }); is there way solve this? you should use variable, value of this changes each function call, , inside callback $.getjson this no longer element. $('.class').each(function() { var self = this; $.getjson(url, function(data) { self.id = data.id; }); }); another option built in arguments in each() $('.class').each(function(index, element) { $.getjson(url, function(data) { element.id = data.id; }); });

while printing address , value of 'x' in function foo1 , address , value of y in foo2, why showing same values both of functions? #include <stdio.h void foo1(int xval) { int x; x = xval; /* print address , value of x here */ } void foo2(int dummy) { int y; /* print address , value of y here */ } int main() { foo1(7); foo2(11); return 0; } output of program is address of x is: 65518 value of x is: 7 address of y is: 65518 value of y is: 7 it's because they're created on stack, unwound after each function call. are created @ same memory address.

i have no idea wrong here. problem array accessing last element contains terminating code. when use i <= sizeof(arr) limiter in for loop, 4 element list works, 3 element list crashes. if replace i < sizeof(arr) , 3 element list works last element in 4 element list ignored. int arraylist(string arr[]) { int choice; (unsigned int = 1; <= sizeof(arr); i++) { cout << << ".

i want retrieve xml element node based on given string value. element node can described @ levels in nested xml, there no specific structure xml has. how in xslt transformation? i use key: <xsl:key name="k1" match="*[not(*)]" use="."/> then can use e.g. <xsl:param name="string-value" select="'foo'"/> and <xsl:variable name="elements" select="key('k1', $string-value)"/> if there can several elements same contents , interested in first use <xsl:variable name="element" select="key('k1', $string-value)[1]"/> that assumes want find elements no child elements string value matches variable, other approaches matching on name of element of course possible: <xsl:key name="k1" match="*" use="local-name()"/> .

i'm aware iframe can't inherit css styles of "main" webpage, if confused. have main page background plain black, white text. iframe doesn't have background colour specified , yet black, same main page. however, other css properties in main page have defined separately iframe if want them used. why this? if not set background of html document (by setting on html element or body element), browser default used, , can expected initial value, transparent . this means page embedded in page iframe element, can expect background of embedding page shine through.

so i'm using r logistic regression, i'm using offsets. mylogit <- glm(y ~ x1 + offset(0.2*x2) + offset(0.4*x3), data = test, family = "binomial") the output, shows single coefficient, intercept , 1 of predictors, x1. coefficients: (intercept) x1 0.5250748 0.0157259 my question: how raw prediction each observation model? more specifically, if use predict function, include features , coefficients, though model coefficients listed containing intercept , x1? prob = predict(mylogit,test,type=c("response")) do have use predict function? "mylogit" object contain can compute directly from? (yes looked @ documentation on glm, still confused). thank patients. i can report results of experiments glm , offset() . not appear (at least experiment) call predict give results take offset account. rather seems summary.glm needed purpose. started rather mangled modification of 1st example in

i'm working on iterator family, iterator classes x have x& operator++() {++x; return *this} in common, seems idea place in common base class. unfortunately, return type changes, since should return reference derived class. the following illustrates problem. f() work, workarounds come g() , h() , not satisfactory: struct { a& f() {return *this;} template <typename t> t& g() {return *(t*)this;} template <typename t> t& h(t& unused) {return *(t*)this;} }; struct b : { int x; b(int x) : x(x) {} }; int main() { b b(12); //b b1 = b.f(); // error: conversion 'a' non-scalar type 'b' requested b b2 = b.g<b>(); // works b b3 = b.h(b); // works } is there way make b b1 = b.f(); work? maybe using c++11 features? use crtp : template<class derived> struct { derived& f() {return static_cast<derived&>(*this);} }; struct b : a<b> {

i want cache arrlist values available in class, define empty arrlist instially , adding values on method , trying global defined arralist values.... class test{ arraylist list=new arraylist(); public void addvalues(){ list.add("one"); list.add("two"); list.add("three"); list.add("four"); list.add("five"); getarrlstvalues(); } public void getarrlstvalues(){ system.out.println("size of cache arralist=" +list.size()); //why showing 0 size } public static void main(string args[]) { test obj=new test(); obj.addvalues(); } } in code add values this.list , check obj.getarrlstvalues() , when this != obj . so never update same list at! you can use this.getarrlstvalues() (or getarrlstvalues() ) , remove line: test obj=new test()

in screen have 2 view horizontally near each other. want width of first view twice of width of second view. i man example, if right view has width=200 second 1 show with=100 . as search , in auto-layout, has options alignments , spaces between views. has option defining such relationships too? you can programmatically adding manual constraints work autolayout. i'm sure using interfacebuilder option. uiview *firstview; uiview *secondview; [firstview addconstraint:[nslayoutconstraint constraintwithitem:secondview attribute:nslayoutattributewidth relatedby:nslayoutrelationequal toitem:firstview attribute:nslayoutattributewidth multiplier:2.0

i have passing experience xargs, don't quite know how this: i have list of archives retrieved tarsnap using tarsnap --list-archives i want delete archives day (there 24 made each day) i can use xargs accomplish this: tarsnap --list-archives | grep 2014-06-09 | xargs -n 1 tarsnap -df however runs tarsnap on , on again 1 argument @ time (which expected): tarsnap -df 2014-06-09-00 tarsnap -df 2014-06-09-01 tarsnap -df 2014-06-09-02 ... etc ... the tarsnap documentation states can delete multiple archives passing in multiple -f flags: tarsnap -d -f 2014-06-09-00 -f 2014-06-09-01 -f 2014-06-09-02 # ... , on is there way accomplish xargs? (aside: might pointless this, since have feeling running tarsnap multiple -f flags causes tarsnap run multiple times, 1 argument @ time... wrong) using idea quite similar @choroba's, can rid of grep altogether , use sed instead: tarsnap --list-archives | sed -n '/2014-06-09/s/^/-f /p' | xargs tarsnap -

in code, use function simple thing: takes records selected given condition , adds give text "errors" column: dterr <- function (dtin, condition, errtext) { if (!is.element('errors', names(dtin))) {dtin[,errors:=""];} dtin[eval(substitute(condition)), errors:={paste0(errors, errtext)}]; invisible(dtin); } (i thankful people helped previous question eval(substitute) ) so, in simple cases function works expected: dt1 <- fread( "id,cola,colb id1,3,xxx id2,0,zzz id3,na,yyy id4,0,aaa ") mynum=0 dterr(dt1, cola>mynum, "positive"); dt1 # id cola colb errors # 1: id1 3 xxx positive # 2: id2 0 zzz # 3: id3 na yyy # 4: id4 0 aaa but when try call function, in combination variable defined inside, error: myfun <- function(){ mynum2=1; dterr(dt1, cola>mynum2, "big!"); } myfun() # error in eval(expr, envir, enclos) : object 'my
