anybody maybe found workaround bug: https://bugzilla.xamarin.com/show_bug.cgi?id=30513 ? it drives me crazy... screenshoot exception report got async method. here 1 solution worked me. add handler in application or main activity androidenvironment.unhandledexceptionraiser += delegate(object sender, raisethrowableeventargs args){ typeof (system.exception).getfield("stack_trace", bindingflags.nonpublic | bindingflags.instance) .setvalue(args.exception, null); throw args.exception; }; the explanation here in last post https://forums.xamarin.com/discussion/45219/stack-trace-not-captured-properly

so let have form id #form has 2 input fields, namely title & price. i click on edit button somewhere in application has data attributes (e.g data-title="apple" data-price="10")that assigned #form upon clicking button. the obvious solution works $("#name").val($(this).data('name')); $("#price").val($(this).data('price')); this looks bad when have many fields. trying work $('#form').data($(this).data()); , more or less in single like have tried many ways no success any appreciated you create jquery plugin can call element contains data points , have apply data based on key elements within form of same name. example below $.fn.applydata = function(form) { $form = $(form); $.each($(this).data(), function(i, key) { $form.find('#' + i).val(key); }); }; jsfiddle: http://jsfiddle.net/lcm8s/43/

the definition of c library function memmove following: void* memmove(void *s1, const void *s2, size_t n) { char *sc1; const char *sc2; sc1 = s1; sc2 = s2; ... } i'm wondering why need use void* , const void* parameters' type. why not directly char* , const char* ? update int test_case[] = {1, 2, 3, 4, 5, 6, 7, 8, 10}; memmove(test_case+4, test_case+2, sizeof(int)*4); output: test_case = {1, 2, 3, 4, 3, 4, 5, 6, 10} void * generic pointer type. memmove supposed manipulate memory regardless of type of objects in memory. similarly memcpy . compare strcpy uses char * parameters because it's supposed manipulate strings.

i've been looking through site haven't found answer 1 yet. it easiest (for me @ least) explain question example. i don't understand why valid: #include <stdio.h> int main(int argc, char* argv[]) { char *mystr = "hello"; } but produces compiler warning ("initialization makes pointer integer without cast"): #include <stdio.h> int main(int argc, char* argv[]) { int *myint = 5; } my understanding of first program creates variable called mystr of type pointer-to-char, value of address of first char ('h') of string literal "hello". in other words initialization not pointer, define object ("hello" in case) pointer points to. why, then, int *myint = 5; seemingly not achieve analogous this, i.e. create variable called myint of type pointer-to-int, value of address of value '5'? why doesn't initialization both give me pointer , define object pointer points to? in fact, can using ...

i'm using method of fetching data sqlite3 database: while(1){ rc = sqlite3_step(stmt); if(rc == sqlite_row){ ... } else if(rc == sqlite_done){ break; } } what not if else construct, looks rather clunky here. , besides, knows if else evil. so, there method of fetching data sqlite , like: while(sqlite3_step(stmt)){ ... } or, probably, there fetch method or similar that. i want know other people in real world projects. something should job, though sure check errors after exiting loop. while((rc = sqlite3_step(stmt)) == sqlite_row) { ... } edit: note doesn't account if database busy, can correct either conditional goto after loop, or outside loop continues while rc it's not equal sqlite_done .

i displaying number of tiles vary in height see below image , thought had solved issue without using masonry using css columns. tiles: my code : -moz-column-count: 2; -moz-column-gap: 4px; -webkit-column-count: 2; -webkit-column-gap: 4px; column-count: 2; column-gap: 4px; each tile has ng-click runs function - passing exercise object function. the column css offsetting tiles one. example if click on tip toe line walking - passed object side step across beam - offset 1 place in grid. if run normal css functions perfectly. why column css display correctly pass incorrect variable? edit works fine in safari on ipad.

i have function parameter takes object , if of correct type need access last element in option[list[int]] . have working solution seems clumsy. in case there not items in obj.listofthings need have i have value 0. there better way achieve this? val = foo match { case obj: bar => obj.listofints match { case some(ints) => ints.last case _ => 0 } case _ => 0 } technically return option[int] . i'm still pretty new scala , learn better approaches sort of problems. in case seems ende neu suggested right way go: val = foo match { case obj: bar => obj.listofints.map(_.last /* throws exception when list empty*/).getorelse(0) case _ => 0 } but if you'll see have bug in code, in case that obj.listofints some(nil) , because in case nosuchelementexception trying call last on empty list. try code foo = bar(some(nil)) , see yourself. when use option[list] think if want. after thinking scrap ...
