i'm working on application in eclipse have 5 tab , have spent time have big problem : when 1 of tabs activated next tab , prev tab loading , oncreated() method called don't need need calling oncreated() method when switching tabs this project files mainactivity.java package info.androidhive.tabsswipe; import info.androidhive.tabsswipe.adapter.tabspageradapter; import ir.zinoo.mankan.r; import android.app.actionbar; import android.app.actionbar.tab; import android.app.fragmenttransaction; import android.graphics.color; import android.graphics.drawable.colordrawable; import android.view.menu; import android.view.menuitem; import android.widget.toast; import android.os.bundle; import android.support.v4.app.fragmentactivity; import android.support.v4.view.viewpager; import android.content.sharedpreferences; public class mainactivity extends fragmentactivity implements actionbar.tablistener { private viewpager viewpager; private tabspageradapter

i have situation there either 4 options or less. options a,b,c,d (or a,c or a,c,d...ect). , each option associated integer value 0 - 4000. , if 4 options a,b,c,d available want represent 0-999, b represent 1000-1999...ect. if options a,c,d want = 0-999, c = 1000-2999 & d = 3000-4000, , on different types of options, can input values depending on options available (not spilt evenly). bunch of if statements seems impractical. if (a & b & c & d) { = 0-999; b = 1000-1999; ... } else if(a & c & d) { ... } //and on , on lot of combinations there must better way set up, , more efficient bunch of if statements, how go doing this? thanks in advance. keep options in array, nsarray *options=@[@"a",@"b",@"c"]; int i=-1; (nsstring *s in options) { // assign options value i++; // s = i+999 stuff assign value option. i=i+999; } if want do.

i'm using laravel findornew() entry 2 parameters, or create new one: $option = \app\option::findornew(['user_id' => $this->id , 'option_name' => $optionname]); i want option user has name in $optionname. problem checks user_id, , not create new 1 when option_name not exist.. instead "finds" 1 not match $optionname value.. can i'm doing wrong? how can achieve this? tl;dr: you're using wrong method. you're looking firstornew() method, not findornew() . explanation: the findornew() extension of find() method, works on ids only. takes 2 parameters, first being id (or array of ids) find, , second being columns retrieve. it's treating array you've passed in array of ids find. the firstornew() method takes 1 parameter: array of attributes search for. turn array clause, , call first() on query builder. if no results returned, returns new instance attributes filled in.

we have 1 vb.net winform application built against .net framework 1.1 uses referenced assemblies (class library) .net 1.1 gac location , works fine. but later have migrated referenced assembly files .net 4.0 , deployed locally in application executable's folder. so manifest file of main application in .net 1.1 has referenced assemblies in .net framewok 4.0 and application works if have .net framework 1.1 installed on client machine , if remove .net framewok 1.1 application crashes while getting data referenced assemblies. client machine has .net framewok 4.0 installed , .net runtime supports backward compatibility why application crashes after removing .net 1.1 framework. please shed light on issue. thanks. first of all, .net backward compatibility not guarantee correct behavior. means later version of runtime (4.0) can run assembly of earlier version (1.1). since correct behavior not guaranteed, 4.0 runtime not implicitly run assemblies built earlier version
