i'm trying make app can save lot of structured objects in database. using spring data jpa (with hibernate + mysql (myisam tables + foreign keys)) write code data services easy , pleasant using spring data repositories performance slow. for example, tried insert 100 records in 1 table , takes 8,5 sec. i've try same insert operations straight in mysql cmd (using hardcoded "insert strings" in procedure) , shows me time - 0,85 sec. such result me slow, problem of mysql reading forum have found post says spring data jpa can't bulk insert properly. how can make app more faster? want use bulk insert operations size 1000 or more. the situation complicated fact can't store object db in 1 bulk (despite size of bulk) to make clearer: the objectgame contains list of objectround objectgame contains list of objectgameplayer objectround contains list of objectroundcard objectgameplayer contains list of objectplayercard objectgameplayer contains list of o

my app should start landscape mode. change orientation of phone. how manually.i tried doesn't work. shouldautorotatetointerfaceorientation: is there other way?? in project settings, can set orientations app permits. set landscapeleft , landscaperight. prevent app going potrait mode, irrespective of orientation of device before app started. manually force change orientation in ios, cannot directly set device orientation manually. however, can use method work done. [[uiapplication sharedapplication] setstatusbarorientation:uiinterfaceorientationlandscapeleft animated:no]; the usual way alternatively, can goto implementation file can specify allowed orientations in method: - (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation { //return yes if want allow orientations return uiinterfaceorientationlandscaperight; //if want allow landscape right &c }

consider code: public int downloadsoundfile() { using (var x= new x()) { return x.value; } } and code: public int downloadsoundfile() { if (x!=null) { return x.value; } } the first code doesn't give compile time errors in second code error: not code paths return value this means should return value outside of if scope. why have return value outside of if scope don't need return value outside of using scope? why should return value out of if scope don't need return value out of using scope? because if scope might not execute (if condition not satisfied) whereas body of using scope guaranteed execute (it either return result or throw exception acceptable compiler). if scope method undefined if condition not satisfied , compiler refuses that. so should decide value return if condition wrote not satisfied: public int downloadsoundfile() { if (x != null) { return x.value; }

i trying .delay() , .fadeout() .remove() but delay , fadeout has no effect in remove here code: jquery("#container").delegate(".remove", "click", function (e) { e.preventdefault(); var parent = jquery(this).data('parent'); jquery(this).closest('.' + parent).fadeout(1000).delay(1000).remove(); }) why not jquery(this).closest('.' + parent).fadeout(1000, function(){ $(this).remove() }); you should make use of complete callback provided .fadeout() in case jquery("#container").on("click", ".remove", function (e) { e.preventdefault(); var $this = jquery(this), parent = $this.data('parent'); $this.closest('.' + parent).fadeout(1000).delay(1000).remove(); })
