i have class has property of type sqlconnection . sqlconnection implements idisposable . have following questions: should class implement idisposable because has property of type idisposable ? if yes, need dispose property explicitly when disposing instance of class? e.g. public class helper : idisposable { // assume it's other idisposable type. sqlconnection example. public sqlconnection sqlconnection { get; set; } public void dispose() { if (sqlconnection!= null) { sqlconnection.dispose(); } } } note : know there pattern followed while implementing idisposable question specific case mentioned above. it depends . if class creates , owns idisposable must dispose (so, both answers "yes" ). if class uses idisposable must not dispose (so first answer is, usually, "no" , second answer "no" ). in case, seems helper class public class helper { // note, c

i have jquery dynamically created form need able edit , change in option, code below picks selected value because second line of code sets default value defined selected, on changing drop-down, no matter select keeps original value - , presume because it's been selected second line, how break on changing option text (i have no values, text). $('#msgbox4').html($('#msgbox4').html() + '<div class="table-row"><div class="table-col-l">type:</div><div class="table-col-r"><select id="type2" required="required"><option selected value="" disabled> -- select option -- </option><option>holiday</option><option>sick</option><option>working off site</option></select></div></div>') $("#type2 > option:contains('"+calevent.description+"')").attr("selected", "selected&qu

this question has answer here: is possible change values of array when doing foreach in javascript? 7 answers i have array of objects , foreach() , one: $scope.things = [ {x: 2}, {x: 4}, {x: 5} ]; angular.foreach($scope.things, function(thing) { //pick 1 of lines @ time //thing.x += 10; // <--- works //thing.k = thing.x + 1; // <--- works //thing = {k: thing.x + 10, o: thing.x - 1}; // <--- doesn't work // }); console.log($scope.things); and "works", "works" , "doesn't work" mean: x added 10, , final array looks {x: 12}, {x: 14}, {x: 15} k created, , final array looks {x: 2, k: 3}, {x: 4, k: 5}, {x: 5, k: 6} thing isn't replaced, , array of things looks @ beginning. my questions are: why happening? is expected behavior? how can replace each thing ?

i have following regex: 1|2|3|4|5|6 it's sql part, , want match 6 ids. problem regex matches integers 11, 12, 13, 14, 15, 16, 23, etc. how can form regex match 6 specific integers? in order use "shorter" queries, can use alternation character class regexp : select * table id regexp '^([1-6]|23)$' the character class [1-6] matches numbers 1 6 , , | used list other alternatives. grouping (...) makes anchors ^ (beginning of string) , $ (end of string) apply possible alternatives. if ids passed separately , regex created dynamically, use alternation: ^(23|6|5|4|3|2|1)$ however, if have small subset of ids, you'd better use or syntax list alternatives since non-regex solutions less resource-consuming.
