i have set of radio buttons, , 2 of them need prompt user confirmation dialog before allowing value change. this, handle click event , set autocheck property false on each of these radio buttons. however, selected radiobuttons no longer unchecked when set check property true on clicked radiobutton. right i'm looping through controls on panel , making sure none of other radiobuttons checked, there more efficient way this? you can use variable store last checked radiobutton: //first, have set lastchecked = radiobutton1 (or of radiobuttons) radiobutton lastchecked; //click event handler used radiobuttons private void radiosclick(object sender, eventargs e) { radiobutton radio = sender radiobutton; if (radio != lastchecked){ radio.checked = true; lastchecked.checked = false; lastchecked = radio; } //else radio.checked = !radio.checked; } if want allow user uncheck radio (a strange behavior), remove // before else clause in code

i wanted test webapp geb , grails , come across strange error. when tried enter numbers 2 or 4 input, these numbers ignored , no number entered. other numbers work fine. error occured when used chrome driver, when switched firefox, works ok. have same problem or know solution? much! e.g. def "test numbers"(){ $("input#someid\\.search") = "0123456789" } then in input (text field), have 01356789. regards, lojza try this: $("yourselector") << "0123456789"

i have setinterval running piece of code 30 times second. works great, when select tab (so tab code becomes inactive), setinterval set idle state reason. i made simplified test case ( http://jsfiddle.net/7f6dx/3/ ): var $div = $('div'); var = 0; setinterval(function() { a++; $div.css("left", a) }, 1000 / 30); if run code , switch tab, wait few seconds , go back, animation continues @ point when switched other tab. animation isn't running 30 times second in case tab inactive. can confirmed counting amount of times setinterval function called each second - not 30 1 or 2 if tab inactive. i guess done design improve performance, there way disable behaviour? disadvantage in scenario. on browsers inactive tabs have low priority execution , can affect javascript timers. if values of transition calculated using real time elapsed between frames instead fixed increments on each interval, not workaround issue can achieve smother animation

i loading assembly @ runtime , trying lot of operations @ runtime going far anyways trying achieve: i have class called student in foreign assembly loading @ runtime public class student { public bool isgood { get; set; } public studenttype st { get; set; } public university university { get; set; } } i can dynamically load object assembly doing like: var assembly = assembly.loadfrom("//path"); type type = assembly.gettype("testframework.student"); var student = activator.createinstance(type); now, comes turn set properties type dynamically loaded foreign assembly. type universitytype = assembly.gettype("testframework.university"); type.getproperty("university").setvalue(student, activator.createinstance(universitytype), null); nice part works too!! but here problem starts. when try assign studenttype enum same assembly fails error object of type 'system.reflection.mdfieldinfo' cannot converted to

the add button comes default masterdetail template in xcode displays + symbol. rather have word "add" instead. tried using following line in viewdidload method: self.navigationitem.rightbarbuttonitem.title = @"add"; to no avail. this because bar button has been created uibarbuttonsystemitemadd so: uibarbuttonitem *addbutton = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemadd target:self action:@selector(insertnewobject:)]; you should rewrite line create bar button item title, this: uibarbuttonitem *addbutton = [[uibarbuttonitem alloc] initwithtitle:@"add" style:uibarbuttonitemstylebordered target:self action:@selector(insertnewobject:)]; you can find in viewdidload method of master view controller.

i have program outputs data fpga. since data changes extremely fast, i'm trying increase speed of program. right printing data this for (int = 0; < 100; i++) { printf("data: %d\n",getdata(i)); } i found using 1 printf increases speed printf("data: %d \n data: %d \n data: %d \n",getdata(1),getdata(2),getdata(3)); however, can see, messy , can't use loop. tried concatenating strings first using sprintf , printing out @ once, it's slow first method. suggestions? edit: i'm printing file first, because realized console scrolling issue. still slow. i'm debugging memory controller external fpga, closer real speed better. if writing stdout, might not able influence all. otherwise, set buffering setvbuf http://en.cppreference.com/w/cpp/io/c/setvbuf std::nounitbuf http://en.cppreference.com/w/cpp/io/manip/unitbuf and un tie input output streams (c++) http://en.cppreference.com/w/cpp/io/basic_ios/tie std::ios_base::s
