Answer : It is not easy to achieve this with an if condition inside the helper method because all the below markups will render a disabled chechbox. <input type="checkbox" disabled> <input type="checkbox" disabled="disabled"> <input type="checkbox" disabled="false"> <input type="checkbox" disabled="no"> <input type="checkbox" disabled="enabled"> This should work in the razor. Simple If condition and rendering what you want. @if(item.Selected) { @Html.CheckBoxFor(modelItem => item.Selected) } else { @Html.CheckBoxFor(modelItem => item.Selected, new { @disabled = "disabled"}) } You may consider writing a custom html helper which renders the proper markup for this. This won't work because <input disabled="anything" /> will result in a disabled control. You need to only have a @disabled property when it should be d

This page describes how to install Ansible on different platforms. Ansible is an agentless automation tool that by default manages machines over the SSH protocol. Once installed, Ansible does not add a database, and there will be no daemons to start or keep running. You only need to install it on one machine (which could easily be a laptop) and it can manage an entire fleet of remote machines from that central point. When Ansible manages remote machines, it does not leave software installed or running on them, so there’s no real question about how to upgrade Ansible when moving to a new version. Prerequisites Control node requirements Managed node requirements Selecting an Ansible version to install Installing Ansible on RHEL, CentOS, or Fedora Installing Ansible on Ubuntu Installing Ansible on Debian Installing Ansible on Gentoo with portage Installing Ansible on FreeBSD Installing Ansible on macOS Installing Ansible on Solaris Installing Ansible on Arch Linux In

Example 1: factorial of 8 function getFactorial($int) { $factorial = 1; for ($i = $int; $i > 1; $i--) { $factorial *= $i; } echo "The factorial of " . $int . " is " . $factorial . ' < br > '; } Example 2: Factorial Number // METHOD ONE const factorialNumber = num => { let factorials = [] for(let i = 1; i <= num; i++) factorials.push(i) return factorials.reduce((acc , curr) => acc * curr, 1) } // METHOD TWO const factorialNumber = num => { let factorial = 1, i = 1 while(i <= num){ factorial *= i; i++ } return factorial } // METHOD THREE function factorialNumber(num) { if(num < 1) return 1 else return factorialNumber(num - 1) * num }

Answer : In the final version of Angular (e.g. Angular 2/4), you can do this this.router.events.subscribe((event) => { if(event.url) { console.log(event.url); } }); Every time the route changes, events Observable has the info. Click here for docs . If you are using "@angular/router": "3.0.0-alpha.7", "@angular/router-deprecated": "2.0.0-rc.2", then this.router.events.subscribe((event) => { console.log('route changed'); }); Here's what I use in my app. You can subscribe to a Route instance to track changes. class MyClass { constructor(private router: Router) { router.subscribe((val) => /*detect changes*/) } }

Answer : Remove this permission <uses-permission android:name="android.permission.CAMERA"/> I faced this error executing my app in android 7. After tests I noticed user permission wasn't in project A but it was in project B, that I only tested in android 5 devices. So I remove that permission in project B in order to run it on other device that targets android 7 and it finally could open. In adittion I added the fileprovider code that Android suggests here https://developer.android.com/training/camera/photobasics.html Hope this helps. hi you can use these permission in your manifest file with other permission, <uses-feature android:name="android.hardware.camera.any" android:required="true" /> <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" /> If still it not working then may be you are using android M,SO you need to programmatically add permissio
