Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.

JDK vs OpenJDK

try this

@NgModule({
  imports: [RouterModule.forRoot(routes,{
    scrollPositionRestoration: 'top'
  })],
  exports: [RouterModule]
})

this code supported angular 6<=

To get started with dotnet core, SqlServer and EF core the below DBContextOptionsBuilder would sufice and you do not need to create App.config file. Do not forget to change the sever address and database name in the below code.

protected override void OnConfiguring(DbContextOptionsBuilder options)
        => options.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Database=TestDB;Trusted_Connection=True;");

To use the EF core SqlServer provider and compile the above code install the EF SqlServer package

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

After compilation before running the code do the following for the first time

dotnet tool install --global dotnet-ef
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet ef migrations add InitialCreate
dotnet ef database update

To run the code

dotnet run

For a local File in case of ReactJS. Try

import Image from "../../assets/image.jpg";

<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
>Hello
</div>

This is the case of ReactJS with inline styling where Image is a local file that you must have imported with a path.

Notifications appear to have changed again (October 2016).

// Register to receive notification

NotificationCenter.default.addObserver(self, selector: #selector(yourClass.yourMethod), name: NSNotification.Name(rawValue: "yourNotificatioName"), object: nil)

// Post notification

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "yourNotificationName"), object: nil)

You simply need to add that line legend: { display: false }

Use attribute binding syntax instead

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    [attr.data-sectionvalue]="section.value">{{ section.text }}</li>  
</ol>

or

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    attr.data-sectionvalue="{{section.value}}">{{ section.text }}</li>  
</ol>

Just restart your AS, then Rebuild your app!

Most IIS sections are locked by default but you can "unlock" them by setting the attribute overrideModeDefault from "Deny" to "Allow" for the relevant section group by modifying the ApplicationHost.config file located in %windir%\system32\inetsrv\config in Administrator mode

The difference between absolute and relative imports come into play only when you import a module from a package and that module imports an other submodule from that package. See the difference:

$ mkdir pkg
$ touch pkg/__init__.py
$ touch pkg/string.py
$ echo 'import string;print(string.ascii_uppercase)' > pkg/main1.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pkg/main1.py", line 1, in <module>
    import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
>>> 
$ echo 'from __future__ import absolute_import;import string;print(string.ascii_uppercase)' > pkg/main2.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 

In particular:

$ python2 pkg/main2.py
Traceback (most recent call last):
  File "pkg/main2.py", line 1, in <module>
    from __future__ import absolute_import;import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 
$ python2 -m pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ

Note that python2 pkg/main2.py has a different behaviour then launching python2 and then importing pkg.main2 (which is equivalent to using the -m switch).

If you ever want to run a submodule of a package always use the -m switch which prevents the interpreter for chaining the sys.path list and correctly handles the semantics of the submodule.

Also, I much prefer using explicit relative imports for package submodules since they provide more semantics and better error messages in case of failure.

None of the above answers is currently working for me. It turns out that .scrollTo is not as widely compatible as .scrollIntoView.

In our App.js, in componentWillMount() we added

this.props.history.listen((location, action) => {
        setTimeout(() => { document.getElementById('root').scrollIntoView({ behavior: "smooth" }) }, 777)
    })

This is the only solution that is working universally for us. root is the ID of our App. The "smooth" behavior doesn't work on every browser / device. The 777 timeout is a bit conservative, but we load a lot of data on every page, so through testing this was necessary. A shorter 237 might work for most applications.

My App.config looks as below:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
</configuration>

I noticed that there is localDB in the path that you mentioned above and has the version v11.0. So I entered (LocalDB\V11.0) in Add Connection dialogue and it worked for me.

Inherit the tableview delegate and datasource. Implement delegates what you need.

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self
    }

And Finally implement this delegate

     func tableView(_ tableView: UITableView, didSelectRowAt  
     indexPath: IndexPath) {
     print("row selected : \(indexPath.row)")
  }

I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???

1. Add dependencies inside your build.gradle file:

   dependencies {
       compile 'com.android.support:design:23.1.1'
   }
   

2. Add TabLayout inside your layout

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:orientation="vertical">
   
       <android.support.v7.widget.Toolbar
           android:id="@+id/toolbar"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:background="?attr/colorPrimary"/>
   
       <android.support.design.widget.TabLayout
           android:id="@+id/tab_layout"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"/>
   
       <android.support.v4.view.ViewPager
           android:id="@+id/pager"
           android:layout_width="match_parent"
           android:layout_height="match_parent"/>
   
   </LinearLayout>
   

3. Setup your Activity like this:

   import android.os.Bundle;
   import android.support.design.widget.TabLayout;
   import android.support.v4.app.Fragment;
   import android.support.v4.app.FragmentManager;
   import android.support.v4.app.FragmentPagerAdapter;
   import android.support.v4.view.ViewPager;
   import android.support.v7.app.AppCompatActivity;
   import android.support.v7.widget.Toolbar;
   
   public class TabLayoutActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_pull_to_refresh);
   
           Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
           TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
           ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
   
           if (toolbar != null) {
               setSupportActionBar(toolbar);
           }
   
           viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
           tabLayout.setupWithViewPager(viewPager);
       }
   
       public class SectionPagerAdapter extends FragmentPagerAdapter {
   
           public SectionPagerAdapter(FragmentManager fm) {
               super(fm);
           }
   
           @Override
           public Fragment getItem(int position) {
               switch (position) {
                   case 0:
                       return new FirstTabFragment();
                   case 1:
                   default:
                       return new SecondTabFragment();
               }
           }
   
           @Override
           public int getCount() {
               return 2;
           }
   
           @Override
           public CharSequence getPageTitle(int position) {
               switch (position) {
                   case 0:
                       return "First Tab";
                   case 1:
                   default:
                       return "Second Tab";
               }
           }
       }
   
   }
   

v1.42 is adding some nice refinements to how folds look and function. See https://github.com/microsoft/vscode-docs/blob/vnext/release-notes/v1_42.md#folded-range-highlighting:

Folded Range Highlighting

Folded ranges now are easier to discover thanks to a background color for all folded ranges.

Fold highlight color Theme: Dark+

The feature is controled by the setting editor.foldingHighlight and the color can be customized with the color editor.foldBackground.

"workbench.colorCustomizations": { "editor.foldBackground": "#355000" }

Folding Refinements

Shift + Click on the folding indicator first only folds the inner ranges. Shift + Click again (when all inner ranges are already folded) will also fold the parent. Shift + Click again unfolds all.

When using the Fold command (kb(editor.fold))] on an already folded range, the next unfolded parent range will be folded.

In Swift 3.0, register a class for your UITableViewCell like this :

tableView.register(UINib(nibName: "YourCellXibName", bundle: nil), forCellReuseIdentifier: "Cell")

In Certain situations, Setting the UICollectionViewFlowLayout in viewDidLoador ViewWillAppear may not effect on the collectionView.

Setting the UICollectionViewFlowLayout in viewDidAppear may cause see the changes of the cells sizes in runtime.

Another Solution, in Swift 3 :

extension YourViewController : UICollectionViewDelegateFlowLayout{

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
        return UIEdgeInsets(top: 20, left: 0, bottom: 10, right: 0)
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        let collectionViewWidth = collectionView.bounds.width
        return CGSize(width: collectionViewWidth/3, height: collectionViewWidth/3)
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
        return 0
    }
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 20
    }
}

I had faced same problem while trying to create decision tree through pydotplus and graphviz. And used the path variable method to resolve this issue.

Below are the exact steps I used:

1. Although I already had graphviz through conda install command , I re-downloaded the latest package from below path. https://graphviz.gitlab.io/_pages/Download/Download_windows.html Downloaded : graphviz-2.38.zip (Stable Release)

2. Copied the extracted folder under following path on C: Drive. C:\Program Files (x86)\

3. Modified the system path variable and added following path to it. Path Variable : Control Panel > System and Security > System > Advance system Setting > Environment Variable > Path C:\Program Files (x86)\graphviz-2.38\release\bin;

4. After adding above path to environment variable , restarted the system.

5. It worked fine , and I was able to create Decision tree into png.

If you don't care about this question being specifically about a tableview, and you'd just like to center one view on top of another view here's to do it:

    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0)
    parentView.addConstraint(horizontalConstraint)

    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)
    parentView.addConstraint(verticalConstraint)

In the initialization chunk I define a function

pagebreak <- function() {
  if(knitr::is_latex_output())
    return("\\newpage")
  else
    return('<div style="page-break-before: always;" />')
}

In the markdown part where I want to insert a page break, I type

`r pagebreak()`

Short answer: I think tgbaggio is right. You hit HDFS throughput limits on your executors.

I think the answer here may be a little simpler than some of the recommendations here.

The clue for me is in the cluster network graph. For run 1 the utilization is steady at ~50 M bytes/s. For run 3 the steady utilization is doubled, around 100 M bytes/s.

From the cloudera blog post shared by DzOrd, you can see this important quote:

I’ve noticed that the HDFS client has trouble with tons of concurrent threads. A rough guess is that at most five tasks per executor can achieve full write throughput, so it’s good to keep the number of cores per executor below that number.

So, let's do a few calculations see what performance we expect if that is true.

Run 1: 19 GB, 7 cores, 3 executors

• 3 executors x 7 threads = 21 threads
• with 7 cores per executor, we expect limited IO to HDFS (maxes out at ~5 cores)
• effective throughput ~= 3 executors x 5 threads = 15 threads

Run 3: 4 GB, 2 cores, 12 executors

• 2 executors x 12 threads = 24 threads
• 2 cores per executor, so hdfs throughput is ok
• effective throughput ~= 12 executors x 2 threads = 24 threads

If the job is 100% limited by concurrency (the number of threads). We would expect runtime to be perfectly inversely correlated with the number of threads.

ratio_num_threads = nthread_job1 / nthread_job3 = 15/24 = 0.625
inv_ratio_runtime = 1/(duration_job1 / duration_job3) = 1/(50/31) = 31/50 = 0.62

So ratio_num_threads ~= inv_ratio_runtime, and it looks like we are network limited.

This same effect explains the difference between Run 1 and Run 2.

Run 2: 19 GB, 4 cores, 3 executors

• 3 executors x 4 threads = 12 threads
• with 4 cores per executor, ok IO to HDFS
• effective throughput ~= 3 executors x 4 threads = 12 threads

Comparing the number of effective threads and the runtime:

ratio_num_threads = nthread_job2 / nthread_job1 = 12/15 = 0.8
inv_ratio_runtime = 1/(duration_job2 / duration_job1) = 1/(55/50) = 50/55 = 0.91

It's not as perfect as the last comparison, but we still see a similar drop in performance when we lose threads.

Now for the last bit: why is it the case that we get better performance with more threads, esp. more threads than the number of CPUs?

A good explanation of the difference between parallelism (what we get by dividing up data onto multiple CPUs) and concurrency (what we get when we use multiple threads to do work on a single CPU) is provided in this great post by Rob Pike: Concurrency is not parallelism.

The short explanation is that if a Spark job is interacting with a file system or network the CPU spends a lot of time waiting on communication with those interfaces and not spending a lot of time actually "doing work". By giving those CPUs more than 1 task to work on at a time, they are spending less time waiting and more time working, and you see better performance.

All the calls to UI should be asynchronous, anything you change on the UI like updating table or changing text label should be done from main thread. using DispatchQueue.main will add your operation to the queue on the main thread.

Swift 4

DispatchQueue.main.async{
    self.tableView.reloadData()
}

There are Three options to add #pragma_mark in Swift:

1) // MARK: - your text here -

2) // TODO: - your text here -

3) // FIXME: - your text here -

Note: Uses - for add separators

I wanted to share another solution working with the ui router 1.0.0.X

As you may know, stateChangeStart and stateChangeSuccess are now deprecated. https://github.com/angular-ui/ui-router/issues/2655

Instead you should use $transitions http://angular-ui.github.io/ui-router/1.0.0-alpha.1/interfaces/transition.ihookregistry.html

This is how I achieved it:

First I have and AuthService with some useful functions

angular.module('myApp')

        .factory('AuthService',
                ['$http', '$cookies', '$rootScope',
                    function ($http, $cookies, $rootScope) {
                        var service = {};

                        // Authenticates throug a rest service
                        service.authenticate = function (username, password, callback) {

                            $http.post('api/login', {username: username, password: password})
                                    .success(function (response) {
                                        callback(response);
                                    });
                        };

                        // Creates a cookie and set the Authorization header
                        service.setCredentials = function (response) {
                            $rootScope.globals = response.token;

                            $http.defaults.headers.common['Authorization'] = 'Bearer ' + response.token;
                            $cookies.put('globals', $rootScope.globals);
                        };

                        // Checks if it's authenticated
                        service.isAuthenticated = function() {
                            return !($cookies.get('globals') === undefined);
                        };

                        // Clear credentials when logout
                        service.clearCredentials = function () {
                            $rootScope.globals = undefined;
                            $cookies.remove('globals');
                            $http.defaults.headers.common.Authorization = 'Bearer ';
                        };

                        return service;
                    }]);

Then I have this configuration:

angular.module('myApp', [
    'ui.router',
    'ngCookies'
])
        .config(['$stateProvider', '$urlRouterProvider',
            function ($stateProvider, $urlRouterProvider) {
                $urlRouterProvider.otherwise('/resumen');
                $stateProvider
                        .state("dashboard", {
                            url: "/dashboard",
                            templateUrl: "partials/dashboard.html",
                            controller: "dashCtrl",
                            data: {
                                authRequired: true
                            }
                        })
                        .state("login", {
                            url: "/login",
                            templateUrl: "partials/login.html",
                            controller: "loginController"
                        })
            }])

        .run(['$rootScope', '$transitions', '$state', '$cookies', '$http', 'AuthService',
            function ($rootScope, $transitions, $state, $cookies, $http, AuthService) {

                // keep user logged in after page refresh
                $rootScope.globals = $cookies.get('globals') || {};
                $http.defaults.headers.common['Authorization'] = 'Bearer ' + $rootScope.globals;

                $transitions.onStart({
                    to: function (state) {
                        return state.data != null && state.data.authRequired === true;
                    }
                }, function () {
                    if (!AuthService.isAuthenticated()) {
                        return $state.target("login");
                    }
                });
            }]);

You can see that I use

data: {
   authRequired: true
}

to mark the state only accessible if is authenticated.

then, on the .run I use the transitions to check the autheticated state

$transitions.onStart({
    to: function (state) {
        return state.data != null && state.data.authRequired === true;
    }
}, function () {
    if (!AuthService.isAuthenticated()) {
        return $state.target("login");
    }
});

I build this example using some code found on the $transitions documentation. I'm pretty new with the ui router but it works.

Hope it can helps anyone.

Just to add a bit of extra info over the right solution. Be aware that you'll need this class org.apache.catalina.filters.CorsFilter. So in order to have it, if your tomcat is not 7.0.41 or higher, download 'tomcat-catalina.7.0.41.jar' or higher ( you can do it from http://mvnrepository.com/artifact/org.apache.tomcat/tomcat-catalina ) and put it in the 'lib' folder inside Tomcat installation folders. I actually used 7.0.42 Hope it helps!

You need to remove the object from your data array before you call deleteRowsAtIndexPaths:withRowAnimation:. So, your code should look like this:

// Editing of rows is enabled
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {

        //when delete is tapped
        [currentCart removeObjectAtIndex:indexPath.row];

        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

You can also simplify your code a little by using the array creation shortcut @[]:

[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

I have solved the issue using below code in my DBContext

 
public partial class Q4Sandbox : DbContext
    {
        public Q4Sandbox()
            : base("name=Q4Sandbox")
        {
        }

        public virtual DbSet Employees { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {           
           var instance = System.Data.Entity.SqlServer.SqlProviderServices.Instance;
        }
    }

Thanks to a SO member.

How your URLs look have nothing to do with REST. Anything goes. It actually is an "implementation detail". So just like how you name your variables. All they have to be is unique and durable.

Don't waste too much time on this, just make a choice and stick to it/be consistent. For example if you go with hierarchies then you do it for all your resources. If you go with query parameters...etc just like naming conventions in your code.

Why so ? As far as I know a "RESTful" API is to be browsable (you know..."Hypermedia as the Engine of Application State"), therefore an API client does not care about what your URLs are like as long as they're valid (there's no SEO, no human that needs to read those "friendly urls", except may be for debugging...)

How nice/understandable a URL is in a REST API is only interesting to you as the API developer, not the API client, as would the name of a variable in your code be.

The most important thing is that your API client know how to interpret your media type. For example it knows that :

• your media type has a links property that lists available/related links.
• Each link is identified by a relationship (just like browsers know that link[rel="stylesheet"] means its a style sheet or rel=favico is a link to a favicon...)
• and it knowns what those relationships mean ("companies" mean a list of companies,"search" means a templated url for doing a search on a list of resource, "departments" means departments of the current resource )

Below is an example HTTP exchange (bodies are in yaml since it's easier to write):

Request

GET / HTTP/1.1
Host: api.acme.io
Accept: text/yaml, text/acme-mediatype+yaml

Response: a list of links to main resource (companies, people, whatever...)

HTTP/1.1 200 OK
Date: Tue, 05 Apr 2016 15:04:00 GMT
Last-Modified: Tue, 05 Apr 2016 00:00:00 GMT
Content-Type: text/acme-mediatype+yaml

# body: this is your API's entrypoint (like a homepage)  
links:
  # could be some random path https://api.acme.local/modskmklmkdsml
  # the only thing the API client cares about is the key (or rel) "companies"
  companies: https://api.acme.local/companies
  people: https://api.acme.local/people

Request: link to companies (using previous response's body.links.companies)

GET /companies HTTP/1.1
Host: api.acme.local
Accept: text/yaml, text/acme-mediatype+yaml

Response: a partial list of companies (under items), the resource contains related links, like link to get the next couple of companies (body.links.next) an other (templated) link to search (body.links.search)

HTTP/1.1 200 OK
Date: Tue, 05 Apr 2016 15:06:00 GMT
Last-Modified: Tue, 05 Apr 2016 00:00:00 GMT
Content-Type: text/acme-mediatype+yaml

# body: representation of a list of companies
links:
  # link to the next page
  next: https://api.acme.local/companies?page=2
  # templated link for search
  search: https://api.acme.local/companies?query={query} 
# you could provide available actions related to this resource
actions:
  add:
    href: https://api.acme.local/companies
    method: POST
items:
  - name: company1
    links:
      self: https://api.acme.local/companies/8er13eo
      # and here is the link to departments
      # again the client only cares about the key department
      department: https://api.acme.local/companies/8er13eo/departments
  - name: company2
    links:
      self: https://api.acme.local/companies/9r13d4l
      # or could be in some other location ! 
      department: https://api2.acme.local/departments?company=8er13eo

So as you see if you go the links/relations way how you structure the path part of your URLs does't have any value to your API client. And if your are communicating the structure of your URLs to your client as documentation, then your are not doing REST (or at least not Level 3 as per "Richardson's maturity model")

The following solved my problem of converting string into date

package main

import (
    "fmt"
    "time"
)

func main() {
    value  := "Thu, 05/19/11, 10:47PM"
    // Writing down the way the standard time would look like formatted our way
    layout := "Mon, 01/02/06, 03:04PM"
    t, _ := time.Parse(layout, value)
    fmt.Println(t)
}

// => "Thu May 19 22:47:00 +0000 2011"

Consider a more pragmatic approach to the question of "doing it correctly".

console.log("about to bind scroll fx");

$(window).scroll(function() {

       console.log("scroll bound, loop through div's");

       $('div').each(function(){

If both of those logs output correctly, then its likely the problem exists in your var declaration. To debug that, consider breaking it out into several lines:

var id='#'+$(this).attr('id');

console.log(id);

var off=$(id).offset().top;
var hei=$(id).height();
var winscroll=$(window).scrollTop();
var dif=hei+off-($(window).height());

By doing this, at least during debugging, you may find that the var id is undefined, causing errors throughout the rest of the code. Is it possible some of your div tags do not have id's?

You can always create an ArrayList of Objects. But it will not be very useful to you. Suppose you have created the Arraylist like this:

List<Object> myList = new ArrayList<Object>();

and add objects to this list like this:

myList.add(new Integer("5"));

myList.add("object");

myList.add(new Object());

You won't face any problem while adding and retrieving the object but it won't be very useful. You have to remember at what location each type of object is it in order to use it. In this case after retrieving, all you can do is calling the methods of Object on them.

Try this one it will work

public class Third extends ListActivity {
private ArrayAdapter<String> adapter;
private List<String> liste;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);
     String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
     liste = new ArrayList<String>();
     Collections.addAll(liste, values);
     adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, liste);
     setListAdapter(adapter);
}
 @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
     liste.add("Nokia");
     adapter.notifyDataSetChanged();
  }
}

require section This section contains the packages/dependencies which are better candidates to be installed/required in the production environment.

require-dev section: This section contains the packages/dependencies which can be used by the developer to test her code (or to experiment on her local machine and she doesn't want these packages to be installed on the production environment).

When you're doing this

var model = @Html.Raw(Json.Encode(Model));

You're probably getting a JSON string, and not a JavaScript object.

You need to parse it in to an object:

var model = JSON.parse(model); //or $.parseJSON() since if jQuery is included
console.log(model.Sections);

Most distributions have installed the GUI app file-roller which unpacks tar, zip, rpm and many more.

file-roller --extract-here package.rpm

This will extract the contents in the current directory.

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

sed '/^abc$/,/^mno$/!d;//d' file

golfs two characters better than ppotong's {//!b};d

The empty forward slashes // mean: "reuse the last regular expression used". and the command does the same as the more understandable:

sed '/^abc$/,/^mno$/!d;/^abc$/d;/^mno$/d' file

This seems to be POSIX:

If an RE is empty (that is, no pattern is specified) sed shall behave as if the last RE used in the last command applied (either as an address or as part of a substitute command) was specified.

Are you looking for this selector?:

.ui-menu .ui-menu-item a{
    background:red;
    height:10px;
    font-size:8px;
}

Ugly demo:

http://jsfiddle.net/zeSTc/

Just replace with your code:

.ui-menu .ui-menu-item a{
    color: #96f226;
    border-radius: 0px;
    border: 1px solid #454545;
}

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

in my case adding <clear /> just after <connectionStrings> worked like charm

The headers only remain fixed when the UITableViewStyle property of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.

If you used the data-role collapsible e.g.

    <div id="selector" data-role="collapsible" data-collapsed="true">
    html......
    </div>

then it will close the the expanded div

    $("#selector").collapsible().collapsible("collapse");   

I wasn't using Azure, but I got the same error locally. Using <customErrors mode="Off" /> seemed to have no effect, but checking the Application logs in Event Viewer revealed a warning from ASP.NET which contained all the detail I needed to resolve the issue.

I had this issue when i refereed a library project from a console application, and the library project was using a nuget package which is not refereed in the console application. Referring the same package in the console application helped to resolve this issue.

Seeing the Inner exception can help.

Just add a new table in the td you want. Example: http://jsfiddle.net/AbE3Q/

<table border="1">
  <tr>
    <td>ABC</td>
    <td>ABC</td>
    <td>ABC</td>
    <td>ABC</td>
  </tr>
  <tr>
    <td>Item1</td>
    <td>Item2</td>
    <td>
      <table border="1">
        <tr>
          <td>qweqwewe</td>
          <td>qweqwewe</td>
        </tr>
        <tr>
          <td>qweqwewe</td>
          <td>qweqwewe</td>
        </tr>
        <tr>
          <td>qweqwewe</td>
          <td>qweqwewe</td>
        </tr>
      </table>
    </td>
    <td>Item3</td>
  </tr>
  <tr>
  </tr>
  <tr>

  <tr>
  </tr>

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

I think you want to speed up your cell loading at the time of image loading for cell in the background. For that we have done the following steps:

1. Checking the file exists in the document directory or not.

2. If not then loading the image for the first time, and saving it to our phone document directory. If you don't want to save the image in the phone then you can load cell images directlyin the background.

3. Now the loading process:

Just include: #import "ManabImageOperations.h"

The code is like below for a cell:

NSString *imagestr=[NSString stringWithFormat:@"http://www.yourlink.com/%@",[dictn objectForKey:@"member_image"]];

        NSString *docDir=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
        NSLog(@"Doc Dir: %@",docDir);

        NSString  *pngFilePath = [NSString stringWithFormat:@"%@/%@",docDir,[dictn objectForKey:@"member_image"]];

        BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:pngFilePath];
        if (fileExists)
        {
            [cell1.memberimage setImage:[UIImage imageWithContentsOfFile:pngFilePath] forState:UIControlStateNormal];
        }
        else
        {
            [ManabImageOperations processImageDataWithURLString:imagestr andBlock:^(NSData *imageData)
             {
                 [cell1.memberimage setImage:[[UIImage alloc]initWithData: imageData] forState:UIControlStateNormal];
                [imageData writeToFile:pngFilePath atomically:YES];
             }];
}

ManabImageOperations.h:

#import <Foundation/Foundation.h>

    @interface ManabImageOperations : NSObject
    {
    }
    + (void)processImageDataWithURLString:(NSString *)urlString andBlock:(void (^)(NSData *imageData))processImage;
    @end

ManabImageOperations.m:

#import "ManabImageOperations.h"
#import <QuartzCore/QuartzCore.h>
@implementation ManabImageOperations

+ (void)processImageDataWithURLString:(NSString *)urlString andBlock:(void (^)(NSData *imageData))processImage
{
    NSURL *url = [NSURL URLWithString:urlString];

    dispatch_queue_t callerQueue = dispatch_get_main_queue();
    dispatch_queue_t downloadQueue = dispatch_queue_create("com.myapp.processsmagequeue", NULL);
    dispatch_async(downloadQueue, ^{
        NSData * imageData = [NSData dataWithContentsOfURL:url];

        dispatch_async(callerQueue, ^{
            processImage(imageData);
        });
    });
  //  downloadQueue=nil;
    dispatch_release(downloadQueue);

}
@end

Here's another CSS only solution that works with any HTML layout.

It works with any element you need to switch. Whatever your toggle layout is you just put it inside a couple of elements with the if-collapsed and if-not-collapsed classes inside the toggle element.

The only catch is that you have to make sure you put the desired initial state of the toggle. If it's initially closed, then put a collapsed class on the toggle.

It also requires the :not selector, so it doesn't work on IE8.

HTML example:

<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
  <!--You can put any valid html inside these!-->
  <span class="if-collapsed">Open</span>
  <span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

Less version:

[data-toggle="collapse"] {
    &.collapsed .if-not-collapsed {
         display: none;
    }
    &:not(.collapsed) .if-collapsed {
         display: none;
    }
}

CSS version:

[data-toggle="collapse"].collapsed .if-not-collapsed {
  display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
  display: none;
}

I ended up using a variation of Shawn's solution:

Create a custom UITableView class with a delegate:

protocol CustomTableViewDelegate {
    func CustomTableViewDidLayoutSubviews()
}

class CustomTableView: UITableView {

    var customDelegate: CustomTableViewDelegate?

    override func layoutSubviews() {
        super.layoutSubviews()
        self.customDelegate?.CustomTableViewDidLayoutSubviews()
    }
}

Then in my code, I use

class SomeClass: UIViewController, CustomTableViewDelegate {

    @IBOutlet weak var myTableView: CustomTableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.myTableView.customDelegate = self
    }

    func CustomTableViewDidLayoutSubviews() {
        print("didlayoutsubviews")
        // DO other cool things here!!
    }
}

Also make sure you set your table view to CustomTableView in the interface builder:

Just to help someone who get here... You should not use $parent.$index as it's not really safe. If you add an ng-if inside the loop, you get the $index messed!

Right way

  <table>
    <tr ng-repeat="row in rows track by $index" ng-init="rowIndex = $index">
        <td ng-repeat="column in columns track by $index" ng-init="columnIndex = $index">

          <b ng-if="rowIndex == columnIndex">[{{rowIndex}} - {{columnIndex}}]</b>
          <small ng-if="rowIndex != columnIndex">[{{rowIndex}} - {{columnIndex}}]</small>

        </td>
    </tr>
  </table>

Check: plnkr.co/52oIhLfeXXI9ZAynTuAJ

Also, this could make it works:

@{
Html.RenderPartial("your view", your_model, ViewData);
}

or

@{
Html.RenderPartial("your view", your_model);
}

When I inspected the problem, I have noticed that the following dll were missing in the output folder. The simple solution is copy Entityframework.dll and Entityframework.sqlserver.dll with the app.config to the output folder if the application is on debug mode. At the same time change, the build option parameter "Copy to output folder" of app.config to copy always. This will solve your problem.

This kind of layout problem can be solved with flexbox now, avoiding the need to know heights or control layout with absolute positioning, or floats. OP's main question was how to get a parent to contain children of unknown height, and they wanted to do it within a certain layout. Setting height of the parent container to "fit-content" does this; using "display: flex" and "justify-content: space-between" produces the section/column layout I think the OP was trying to create.

<section id="foo">
    <header>Foo</header>
    <article>
        <div class="main one"></div>
        <div class="main two"></div>
    </article>
</section>    

<div style="clear:both">Clear won't do.</div>

<section id="bar">
    <header>bar</header>
    <article>
        <div class="main one"></div><div></div>
        <div class="main two"></div>
    </article>
</section> 

* { text-align: center; }
article {
    height: fit-content ;
    display: flex;
    justify-content: space-between;
    background: whitesmoke;
}
article div { 
    background: yellow;     
    margin:20px;
    width: 30px;
    height: 30px;
    }

.one {
    background: red;
}

.two {
    background: blue;
}

I Just came across to a similar to this question solution with included some performance statistics.

It seems that example below is faster:

InnerHTML vs jQuery 1 vs appendChild vs innerAdjecentHTML.

Reference: 1) Performance stats 2) API - insertAdjacentHTML

I hope this will help.

Nevermind. I was making this way more complicated than it really needed to be.

This was all that I needed. The rename methods just generate a call to the sp_rename system stored procedure and I guess that took care of everything, including the foreign keys with the new column name.

public override void Up()
{
    RenameTable("ReportSections", "ReportPages");
    RenameTable("ReportSectionGroups", "ReportSections");
    RenameColumn("ReportPages", "Group_Id", "Section_Id");
}

public override void Down()
{
    RenameColumn("ReportPages", "Section_Id", "Group_Id");
    RenameTable("ReportSections", "ReportSectionGroups");
    RenameTable("ReportPages", "ReportSections");
}

@section is for defining a content are override from a shared view. Basically, it is a way for you to adjust your shared view (similar to a Master Page in Web Forms).

You might find Scott Gu's write up on this very interesting.

Edit: Based on additional question clarification

The @RenderSection syntax goes into the Shared View, such as:

<div id="sidebar">
    @RenderSection("Sidebar", required: false)
</div>

This would then be placed in your view with @Section syntax:

@section Sidebar{

}

In MVC3+ you can either define the Layout file to be used for the view directly or you can have a default view for all views.

Common view settings can be set in _ViewStart.cshtml which defines the default layout view similar to this:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

You can also set the Shared View to use directly in the file, such as index.cshtml directly as shown in this snippet.

@{
    ViewBag.Title = "Corporate Homepage";
    ViewBag.BodyID = "page-home";
    Layout = "~/Views/Shared/_Layout2.cshtml";
}

There are a variety of ways you can adjust this setting with a few more mentioned in this SO answer.

using json.loads will turn your data into a python dictionary.

Dictionaries values are accessed using ['key']

resp_str = {
  "name" : "ns1:timeSeriesResponseType",
  "declaredType" : "org.cuahsi.waterml.TimeSeriesResponseType",
  "scope" : "javax.xml.bind.JAXBElement$GlobalScope",
  "value" : {
    "queryInfo" : {
      "creationTime" : 1349724919000,
      "queryURL" : "http://waterservices.usgs.gov/nwis/iv/",
      "criteria" : {
        "locationParam" : "[ALL:103232434]",
        "variableParam" : "[00060, 00065]"
      },
      "note" : [ {
        "value" : "[ALL:103232434]",
        "title" : "filter:sites"
      }, {
        "value" : "[mode=LATEST, modifiedSince=null]",
        "title" : "filter:timeRange"
      }, {
        "value" : "sdas01",
        "title" : "server"
      } ]
    }
  },
  "nil" : false,
  "globalScope" : true,
  "typeSubstituted" : false
}

would translate into a python diction

resp_dict = json.loads(resp_str)

resp_dict['name'] # "ns1:timeSeriesResponseType"

resp_dict['value']['queryInfo']['creationTime'] # 1349724919000

Had the same problem, while differently from other answers in my case I use ASP.NET to develop the WebAPI server.

I already had Corps allowed and it worked for GET requests. To make POST requests work I needed to add 'AllowAnyHeader()' and 'AllowAnyMethod()' options to the list of Corp options.

Here are essential parts of related functions in Start class look like:

ConfigureServices method:

    services.AddCors(options =>
    {
        options.AddPolicy(name: MyAllowSpecificOrigins,
                          builder =>
                          {
                              builder
                                  .WithOrigins("http://localhost:4200")
                                  .AllowAnyHeader()
                                  .AllowAnyMethod()
                                  //.AllowCredentials()
                                  ;
                          });
    });

Configure method:

        app.UseCors(MyAllowSpecificOrigins);

Found this from:

One important thing about git config:

git config has --local, --global and --system levels and corresponding files.

So you may use git config --local, git config --global and git config --system.

By default, git config will write to a local level if no configuration option is passed. Local configuration values are stored in a file that can be found in the repository's .git directory: .git/config

Global level configuration is user-specific, meaning it is applied to an operating system user. Global configuration values are stored in a file that is located in a user's home directory. ~/.gitconfig on Unix systems and C:\Users\<username>\.gitconfig on Windows.

System-level configuration is applied across an entire machine. This covers all users on an operating system and all repositories. The system level configuration file lives in a gitconfig file off the system root path. $(prefix)/etc/gitconfig on Linux systems. On Windows this file can be found in C:\ProgramData\Git\config.

So your option is to find that global .gitconfig file and edit it.

Or you can use git config --global --list.

This is exactly the line what you need.

I just coded an extension for python-markdown, which uses its parser to retrieve headings, and outputs a TOC as Markdown-formatted unordered list with local links. The file is

• md_toc.py (was md_toc.py)

... and it should be placed in markdown/extensions/ directory in the markdown installation. Then, all you have to do, is type anchor <a> tags with an id="..." attribute as a reference - so for an input text like this:

$ cat test.md 
Hello
=====

## <a id="sect one"></a>SECTION ONE ##

something here

### <a id='sect two'>eh</a>SECTION TWO ###

something else

#### SECTION THREE

nothing here

### <a id="four"></a>SECTION FOUR

also...

... the extension can be called like this:

$ python -m markdown -x md_toc test.md 
* Hello
    * [SECTION ONE](#sect one)
        * [SECTION TWO](#sect two)
            * SECTION THREE
        * [SECTION FOUR](#four)

... and then you can paste back this toc in your markdown document (or have a shortcut in your text editor, that calls the script on the currently open document, and then inserts the resulting TOC in the same document).

Note that older versions of python-markdown don't have a __main__.py module, and as such, the command line call as above will not work for those versions.

This was helpful for me:

    jQuery('button').click( function(e) {
    jQuery('.in').collapse('hide');
});

It's collapsed already open section. Thnks to GrafiCode Studio

I had the same problem, none of the solutions worked for me, Finally I removed the System.Web.MVC and added again Then everything was back to normal and my problem solved.

I searched for the error in the web and came to this page. I am using Visual Studio 2015 and this is my first MVC project.

If you miss the @ symbol before the render section you will get the same error. I would like to share this for future beginners.

 @RenderSection("headscripts", required: false)

In IIS 8.5/ Windows 2012R2, Nothing mentioned here worked for me. I don't know what is meant by Removing WebDAV but that didn't solve the issue for me.

What helped me is the below steps;

1. I went to IIS manager.
2. In the left panel selected the site.
3. In the left working area, selected the WebDAV, Opened it double clicking.
4. In the right most panel, disabled it.

Now everything is working.

The best way to answer your question is to see it in action.

<a id="test" onclick="alert('test')"> test </a> ?

In the js

var test = document.getElementById('test');
console.log( test.onclick ); 

As you see in the console, if you're using chrome it prints an anonymous function with the event object passed in, although it's a little different in IE.

function onclick(event) {
   alert('test')
}

I agree with some of your points about inline event handlers. Yes they are easy to write, but i don't agree with your point about having to change code in multiple places, if you structure your code well, you shouldn't need to do this.

Another difference between them is the size of the file:

• Mustache.js has 9kb,
• Handlebars.js has 86kb, or 18kb if using precompiled templates.

To see the performance benefits of Handlebars.js we must use precompiled templates.

titleForHeaderInSection is a delegate method of UITableView so to apply header text of section write as follows,

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
              return @"Hello World";
}

For me, what worked was:

BeautifulSoup(html_text,from_encoding="utf-8")

Hope this helps someone.

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

Why don't you use a combination of HTML/CSS instead? Image maps are obsolete.

This btw is Search Engine Optimised as well :)

Source code follows:

.image-map {
  background: url('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');
  width: 272px;
  height: 92px;
  display: block;
  position: relative;
  margin-top:10px;
  float: left;
}

.image-map > a.map {
  position: absolute;
  display: block;
  border: 1px solid green;
}

<div class="image-map">
    <a class="map" rel="G" style="top: 0px; left: 0px; width: 70px; height: 95px;" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 70px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 120px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="g" style="top: 0px; left: 170px; width: 40px; height: 95px" href="#"></a>
    <a class="map" rel="l" style="top: 0px; left: 210px; width: 20px; height: 95px" href="#"></a>
    <a class="map" rel="e" style="top: 0px; left: 230px; width: 40px; height: 95px" href="#"></a>
</div>

EDIT:

After the numerous negative points this answer has received I have to come back and say that I can clearly see that you don't agree with my answer, but I personally still believe that is a better option than image maps.

Sure it cannot do polygons, it might have issues on manual page zoom, but personally I feel image maps are obsolete although still on the html5 specification. (It makes make more sense nowadays to try and replicate them using html5 canvas instead)

However I guess the target audience for this question does not agree with me.

You could also check this Are HTML Image Maps still used? and see the most highly voted answer just for reference.

DEBUG will show all messages, INFO all besides DEBUG messages, and so on.
Usually one uses either INFO or WARN. This dependens on the company policy.

As complement of this answer you can use $ to get the end matches and * to get matches anywhere in the value name.

Matches anywhere: .col-md, .left-col, .col, .tricolor, etc.

[class*="col"]

Matches at the beginning: .col-md, .col-sm-6, etc.

[class^="col-"]

Matches at the ending: .left-col, .right-col, etc.

[class$="-col"]

You could also organise them into modules. So it would be something like.

./
controllers
    index.js
    indexController.js
app.js

and then in the indexController.js of the controllers export your controllers.

//indexController.js
module.exports = function(){
//do some set up

var self = {
     indexAction : function (req,res){
       //do your thing
}
return self;
};

then in index.js of controllers dir

exports.indexController = require("./indexController");

and finally in app.js

var controllers = require("./controllers");

app.get("/",controllers.indexController().indexAction);

I think this approach allows for clearer seperation and also you can configure your controllers by passing perhaps a db connection in.

Look at the following example, from the HTML5 specification about aside.

It makes clear that what currently is recommended (October 2012) it is to group widgets inside aside elements. Then, each widget is whatever best represents it, a nav, a serie of blockquotes, etc

The following extract shows how aside can be used for blogrolls and other side content on a blog:

<body>
 <header>
  <h1>My wonderful blog</h1>
  <p>My tagline</p>
 </header>
 <aside>
  <!-- this aside contains two sections that are tangentially related
  to the page, namely, links to other blogs, and links to blog posts
  from this blog -->
  <nav>
   <h1>My blogroll</h1>
   <ul>
    <li><a href="http://blog.example.com/">Example Blog</a>
   </ul>
  </nav>
  <nav>
   <h1>Archives</h1>
   <ol reversed>
    <li><a href="/last-post">My last post</a>
    <li><a href="/first-post">My first post</a>
   </ol>
  </nav>
 </aside>
 <aside>
  <!-- this aside is tangentially related to the page also, it
  contains twitter messages from the blog author -->
  <h1>Twitter Feed</h1>

  </blockquote>
  <blockquote cite="http://twitter.example.net/t31219752">
   I'm going to go on vacation soon.
  </blockquote>
 </aside>
 <article>
  <!-- this is a blog post -->
  <h1>My last post</h1>
  <p>This is my last post.</p>
  <footer>

  <h1>My first post</h1>
  <p>This is my first post.</p>
  <aside>
   <!-- this aside is about the blog post, since it's inside the
   <article> element; it would be wrong, for instance, to put the
   blogroll here, since the blogroll isn't really related to this post
   specifically, only to the page as a whole -->
   <h1>Posting</h1>
   <p>While I'm thinking about it, I wanted to say something about

The missing part is:

    display: block;
}

Demo

I had this same problem; I had a master sheet which was a summary of information on other worksheets in my workbook.

If you just want to filter/sort in a worksheet where you have your data stored, and then return it to its original state (no matter what you are filtering/sorting by) just make your first column a Line Item Number.

After your initial filter/sort you can then just resort by the “Line Item Number” to return everything back to normal. NOTE: This only works if you always add new rows to the end of the list in sequence.

Using Mvc Core you can create a tidy TagHelper scripts as seen below. This could easily be morphed into a section tag where you give it a name as well (or the name is taken from the derived type). Note that dependency injection needs to be setup for IHttpContextAccessor.

When adding scripts (e.g. in a partial)

<scripts>
    <script type="text/javascript">
        //anything here
    </script>
</scripts>

When outputting the scripts (e.g. in a layout file)

<scripts render="true"></scripts>

Code

public class ScriptsTagHelper : TagHelper
    {
        private static readonly object ITEMSKEY = new Object();

        private IDictionary<object, object> _items => _httpContextAccessor?.HttpContext?.Items;

        private IHttpContextAccessor _httpContextAccessor;

        public ScriptsTagHelper(IHttpContextAccessor httpContextAccessor)
        {
            _httpContextAccessor = httpContextAccessor;
        }

        public override async Task ProcessAsync(TagHelperContext context, TagHelperOutput output)
        {
            var attribute = (TagHelperAttribute)null;
            context.AllAttributes.TryGetAttribute("render",out attribute);

            var render = false;

            if(attribute != null)
            {
                render = Convert.ToBoolean(attribute.Value.ToString());
            }

            if (render)
            {
                if (_items.ContainsKey(ITEMSKEY))
                {
                    var scripts = _items[ITEMSKEY] as List<HtmlString>;

                    var content = String.Concat(scripts);

                    output.Content.SetHtmlContent(content);
                }
            }
            else
            {
                List<HtmlString> list = null;

                if (!_items.ContainsKey(ITEMSKEY))
                {
                    list = new List<HtmlString>();
                    _items[ITEMSKEY] = list;
                }

                list = _items[ITEMSKEY] as List<HtmlString>;

                var content = await output.GetChildContentAsync();

                list.Add(new HtmlString(content.GetContent()));
            }
        }
    }

My interpretation is: I think of YouTube it has a comment-section, and inside the comment-section there are multiple articles (in this case comments).

So a section is like a div-container that holds articles.

Just keep the following in mind.

In IIS if you have a folder for example called Pages with multiple websites in it. Website will inherit settings from the web.config file from the parent directory. So even if the folder page (in this example Pages) isn't a website but contains a web.config file, all websites listed inside of it will inherit the setting.

If you have main.s file. you can generate object file by GCC and also as

# gcc -c main.s
# as main.s -o main.o

check this link, it will help you learn some binutils of GCC http://www.thegeekstuff.com/2017/01/gnu-binutils-commands/

The section tag provides a more semantic syntax for html. div is a generic tag for a section. When you use section tag for appropriate content, it can be used for search engine optimization also. section tag also makes it easy for html parsing. for more info, refer. http://blog.whatwg.org/is-not-just-a-semantic

For GCC, this is accomplished in two stages:

First compile the data but tell the compiler to separate the code into separate sections within the translation unit. This will be done for functions, classes, and external variables by using the following two compiler flags:

-fdata-sections -ffunction-sections

Link the translation units together using the linker optimization flag (this causes the linker to discard unreferenced sections):

-Wl,--gc-sections

So if you had one file called test.cpp that had two functions declared in it, but one of them was unused, you could omit the unused one with the following command to gcc(g++):

gcc -Os -fdata-sections -ffunction-sections test.cpp -o test -Wl,--gc-sections

(Note that -Os is an additional compiler flag that tells GCC to optimize for size)

Either use window.onload this way

<script>
    window.onload = function() {
        // ...
    }
</script>

or alternatively

<script>
    window.onload = functionName;
</script>

(yes, without the parentheses)

Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.

<body>
    ...

    <script>
        functionName();
    </script>
</body>

Simple: In Visual Studio Report designer
1. Open the report in design mode and delete the dataset from the RDLC File
2. Open solution Explorer and delete the actual (corrupted) XSD file
3. Add the dataset back to the RDLC file.
4. The above procedure will create the new XSD file.
5. More detailed is below.

In Visual Studio, Open your RDLC file Report in Design mode. Click on the report and then Select View and then Report Data from the top line menu. Select Datasets and then Right Click and delete the dataset from the report. Next Open Solution Explorer, if it is not already open in your Visual Studio. Locate the XSD file (It should be the same name as the dataset you just deleted from the report). Now go back and right click again on the report data Datasets, and select Add Dataset . This will create a new XSD file and write the dataset properties to the report. Now your error message will be gone and any missing data will now appear in your reports.

set vimdiff to ignore case

Having started vim diff with

 gvim -d main.sql backup.sql &

I find that annoyingly one file has MySQL keywords in lowercase the other uppercase showing differences on practically every other line

:set diffopt+=icase

this updates the screen dynamically & you can just as easily switch it off again

Binary releases contain computer readable version of the application, meaning it is compiled. Source releases contain human readable version of the application, meaning it has to be compiled before it can be used.

Initially I was just trying the method:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section

but after using this along with:

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section

problem was solved. Sample Program-

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    return 30.0f;
}

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    UIView *sampleView = [[UIView alloc] init];
    sampleView.frame = CGRectMake(SCREEN_WIDTH/2, 5, 60, 4);
    sampleView.backgroundColor = [UIColor blackColor];
    return sampleView;
}

and include UITableViewDelegate protocol.

@interface TestViewController : UIViewController <UITableViewDelegate>

Use This..... You will love it

 <TextView
    android:layout_width="fill_parent"
    android:layout_height="1px"
    android:text=" "
    android:background="#anycolor"
    android:id="@+id/textView"/>

If you are looking for a custom configuration section like following

<CustomApplicationConfig>
        <Credentials Username="itsme" Password="mypassword"/>
        <PrimaryAgent Address="10.5.64.26" Port="3560"/>
        <SecondaryAgent Address="10.5.64.7" Port="3570"/>
        <Site Id="123" />
        <Lanes>
          <Lane Id="1" PointId="north" Direction="Entry"/>
          <Lane Id="2" PointId="south" Direction="Exit"/>
        </Lanes> 
</CustomApplicationConfig>

then you can use my implementation of configuration section so to get started add System.Configuration assembly reference to your project

Look at the each nested elements I used, First one is Credentials with two attributes so lets add it first

Credentials Element

public class CredentialsConfigElement : System.Configuration.ConfigurationElement
    {
        [ConfigurationProperty("Username")]
        public string Username
        {
            get 
            {
                return base["Username"] as string;
            }
        }

        [ConfigurationProperty("Password")]
        public string Password
        {
            get
            {
                return base["Password"] as string;
            }
        }
    }

PrimaryAgent and SecondaryAgent

Both has the same attributes and seem like a Address to a set of servers for a primary and a failover, so you just need to create one element class for both of those like following

public class ServerInfoConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Address")]
        public string Address
        {
            get
            {
                return base["Address"] as string;
            }
        }

        [ConfigurationProperty("Port")]
        public int? Port
        {
            get
            {
                return base["Port"] as int?;
            }
        }
    }

I'll explain how to use two different element with one class later in this post, let us skip the SiteId as there is no difference in it. You just have to create one class same as above with one property only. let us see how to implement Lanes collection

it is splitted in two parts first you have to create an element implementation class then you have to create collection element class

LaneConfigElement

public class LaneConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Id")]
        public string Id
        {
            get
            {
                return base["Id"] as string;
            }
        }

        [ConfigurationProperty("PointId")]
        public string PointId
        {
            get
            {
                return base["PointId"] as string;
            }
        }

        [ConfigurationProperty("Direction")]
        public Direction? Direction
        {
            get
            {
                return base["Direction"] as Direction?;
            }
        }
    }

    public enum Direction
    { 
        Entry,
        Exit
    }

you can notice that one attribute of LanElement is an Enumeration and if you try to use any other value in configuration which is not defined in Enumeration application will throw an System.Configuration.ConfigurationErrorsException on startup. Ok lets move on to Collection Definition

[ConfigurationCollection(typeof(LaneConfigElement), AddItemName = "Lane", CollectionType = ConfigurationElementCollectionType.BasicMap)]
    public class LaneConfigCollection : ConfigurationElementCollection
    {
        public LaneConfigElement this[int index]
        {
            get { return (LaneConfigElement)BaseGet(index); }
            set
            {
                if (BaseGet(index) != null)
                {
                    BaseRemoveAt(index);
                }
                BaseAdd(index, value);
            }
        }

        public void Add(LaneConfigElement serviceConfig)
        {
            BaseAdd(serviceConfig);
        }

        public void Clear()

        protected override ConfigurationElement CreateNewElement()
        {
            return new LaneConfigElement();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((LaneConfigElement)element).Id;
        }

        public void Remove(LaneConfigElement serviceConfig)

        public void Remove(String name)
        {
            BaseRemove(name);
        }

    }

you can notice that I have set the AddItemName = "Lane" you can choose whatever you like for your collection entry item, i prefer to use "add" the default one but i changed it just for the sake of this post.

Now all of our nested Elements have been implemented now we should aggregate all of those in a class which has to implement System.Configuration.ConfigurationSection

CustomApplicationConfigSection

public class CustomApplicationConfigSection : System.Configuration.ConfigurationSection
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(CustomApplicationConfigSection));
        public const string SECTION_NAME = "CustomApplicationConfig";

        [ConfigurationProperty("Credentials")]
        public CredentialsConfigElement Credentials
        {
            get
            {
                return base["Credentials"] as CredentialsConfigElement;
            }
        }

        [ConfigurationProperty("PrimaryAgent")]
        public ServerInfoConfigElement PrimaryAgent
        {
            get
            {
                return base["PrimaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("SecondaryAgent")]
        public ServerInfoConfigElement SecondaryAgent
        {
            get
            {
                return base["SecondaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("Site")]
        public SiteConfigElement Site
        {
            get
            {
                return base["Site"] as SiteConfigElement;
            }
        }

        [ConfigurationProperty("Lanes")]
        public LaneConfigCollection Lanes
        {
            get { return base["Lanes"] as LaneConfigCollection; }
        }
    }

Now you can see that we have two properties with name PrimaryAgent and SecondaryAgent both have the same type now you can easily understand why we had only one implementation class against these two element.

Before you can use this newly invented configuration section in your app.config (or web.config) you just need to tell you application that you have invented your own configuration section and give it some respect, to do so you have to add following lines in app.config (may be right after start of root tag).

<configSections>
    <section name="CustomApplicationConfig" type="MyNameSpace.CustomApplicationConfigSection, MyAssemblyName" />
  </configSections>

NOTE: MyAssemblyName should be without .dll e.g. if you assembly file name is myDll.dll then use myDll instead of myDll.dll

to retrieve this configuration use following line of code any where in your application

CustomApplicationConfigSection config = System.Configuration.ConfigurationManager.GetSection(CustomApplicationConfigSection.SECTION_NAME) as CustomApplicationConfigSection;

I hope above post would help you to get started with a bit complicated kind of custom config sections.

Happy Coding :)

****Edit**** To Enable LINQ on LaneConfigCollection you have to implement IEnumerable<LaneConfigElement>

And Add following implementation of GetEnumerator

public new IEnumerator<LaneConfigElement> GetEnumerator()
        {
            int count = base.Count;
            for (int i = 0; i < count; i++)
            {
                yield return base.BaseGet(i) as LaneConfigElement;
            }
        }

for the people who are still confused about how yield really works read this nice article

Two key points taken from above article are

it doesn’t really end the method’s execution. yield return pauses the method execution and the next time you call it (for the next enumeration value), the method will continue to execute from the last yield return call. It sounds a bit confusing I think… (Shay Friedman)

Yield is not a feature of the .Net runtime. It is just a C# language feature which gets compiled into simple IL code by the C# compiler. (Lars Corneliussen)

• git reset is specifically about updating the index, moving the HEAD.
• git checkout is about updating the working tree (to the index or the specified tree). It will update the HEAD only if you checkout a branch (if not, you end up with a detached HEAD).
  (actually, with Git 2.23 Q3 2019, this will be git restore, not necessarily git checkout)

By comparison, since svn has no index, only a working tree, svn checkout will copy a given revision on a separate directory.
The closer equivalent for git checkout would:

• svn update (if you are in the same branch, meaning the same SVN URL)
• svn switch (if you checkout for instance the same branch, but from another SVN repo URL)

All those three working tree modifications (svn checkout, update, switch) have only one command in git: git checkout.
But since git has also the notion of index (that "staging area" between the repo and the working tree), you also have git reset.

Thinkeye mentions in the comments the article "Reset Demystified ".

For instance, if we have two branches, 'master' and 'develop' pointing at different commits, and we're currently on 'develop' (so HEAD points to it) and we run git reset master, 'develop' itself will now point to the same commit that 'master' does.

On the other hand, if we instead run git checkout master, 'develop' will not move, HEAD itself will. HEAD will now point to 'master'.

So, in both cases we're moving HEAD to point to commit A, but how we do so is very different. reset will move the branch HEAD points to, checkout moves HEAD itself to point to another branch.

On those points, though:

LarsH adds in the comments:

The first paragraph of this answer, though, is misleading: "git checkout ... will update the HEAD only if you checkout a branch (if not, you end up with a detached HEAD)".
Not true: git checkout will update the HEAD even if you checkout a commit that's not a branch (and yes, you end up with a detached HEAD, but it still got updated).

git checkout a839e8f updates HEAD to point to commit a839e8f.

De Novo concurs in the comments:

@LarsH is correct.
The second bullet has a misconception about what HEAD is in will update the HEAD only if you checkout a branch.
HEAD goes wherever you are, like a shadow.
Checking out some non-branch ref (e.g., a tag), or a commit directly, will move HEAD. Detached head doesn't mean you've detached from the HEAD, it means the head is detached from a branch ref, which you can see from, e.g., git log --pretty=format:"%d" -1.

• Attached head states will start with (HEAD ->,
• detached will still show (HEAD, but will not have an arrow to a branch ref.

For me I moved the location of the logfiles and it was only when I changed the name of the file to something else it started again.

It seems if there is a logfile with the same name already existing, nothing happens.

Afterwards I rename the old file and changed the log filename in the config back again to what it was.

With the information provided, I'd model the database to have the following:

POLICIES

• POLICY_ID (primary key)

LIABILITIES

• LIABILITY_ID (primary key)
• POLICY_ID (foreign key)

PROPERTIES

• PROPERTY_ID (primary key)
• POLICY_ID (foreign key)

...and so on, because I'd expect there to be different attributes associated with each section of the policy. Otherwise, there could be a single SECTIONS table and in addition to the policy_id, there'd be a section_type_code...

Either way, this would allow you to support optional sections per policy...

I don't understand what you find unsatisfactory about this approach - this is how you store data while maintaining referential integrity and not duplicating data. The term is "normalized"...

Because SQL is SET based, it's rather alien to procedural/OO programming concepts & requires code to transition from one realm to the other. ORMs are often considered, but they don't work well in high volume, complex systems.

Without jQuery-UI accordion, one can simply do this:

<div class="section">
  <div class="section-title">
    Section 1
  </div>
  <div class="section-content">
    Section 1 Content: Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.
  </div>
</div>

<div class="section">
  <div class="section-title">
    Section 2
  </div>
  <div class="section-content">
    Section 2 Content: Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.
  </div>
</div>

And js

$( ".section-title" ).click(function() {
    $(this).parent().find( ".section-content" ).slideToggle();
});

Try using an AppSettingsSection instead of a NameValueCollection. Something like this:

var section = (AppSettingsSection)config.GetSection(sectionName);
string results = section.Settings[key].Value;

First get the position of the div element upto which u want to scroll by jQuery position() method.
Example : var pos = $("div").position();
Then get the y cordinates (height) of that element with ".top" method.
Example : pos.top;
Then get the x cordinates of the that div element with ".left" method.
These methods are originated from CSS positioning.
Once we get x & y cordinates, then we can use javascript's scrollTo(); method.
This method scrolls the document upto specific height & width.
It takes two parameters as x & y cordinates. Syntax : window.scrollTo(x,y);
Then just pass the x & y cordinates of the DIV element in the scrollTo() function.
Refer the example below ↓ ↓

<!DOCTYPE HTML>
    <html>
    <head>
        <title>
            Scroll upto Div with jQuery.
        </title>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
        <script>
            $(document).ready(function () {
                $("#button1").click(function () {
                    var x = $("#element").position(); //gets the position of the div element...
                    window.scrollTo(x.left, x.top); //window.scrollTo() scrolls the page upto certain position....
                    //it takes 2 parameters : (x axis cordinate, y axis cordinate);
                });
            });
            </script>
    </head>
    <body>
        <button id="button1">
            Click here to scroll
        </button>

        <div id="element" style="position:absolute;top:200%;left:0%;background-color:orange;height:100px;width:200px;">
            The DIV element.
            </div>
        </body>
    </html>

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

I find git stash very useful for temporal handling of all 'dirty' states.

Well another possible cause of this can be simple line break at end of each line and shebang line If you have been coding in windows IDE its possible that windows has added its own line break at the end of each line and when you try to run it on linux the line break cause problems

Visual Studio defines _DEBUG when you specify the /MTd or /MDd option, NDEBUG disables standard-C assertions. Use them when appropriate, ie _DEBUG if you want your debugging code to be consistent with the MS CRT debugging techniques and NDEBUG if you want to be consistent with assert().

If you define your own debugging macros (and you don't hack the compiler or C runtime), avoid starting names with an underscore, as these are reserved.

I needed the div to stop when it reach a certain object, so i did it like this:

var el = $('#followdeal');
    var elpos_original = el.offset().top;
    $(window).scroll(function(){
        var elpos = el.offset().top;
        var windowpos = $(window).scrollTop();
        var finaldestination = windowpos;
        var stophere = ( $('#filtering').offset().top ) - 170;
        if(windowpos<elpos_original || windowpos>=stophere) {
            finaldestination = elpos_original;
            el.stop().animate({'top':10});
        } else {
            el.stop().animate({'top':finaldestination-elpos_original+10},500);
        }
    });

I had the same problem.

A tiny tweak to the smallest one here (the filter/indexOf solution), namely creating an index of the values in one of the arrays using a JavaScript object, will reduce it from O(N*M) to "probably" linear time. source1 source2

function intersect(a, b) {
  var aa = {};
  a.forEach(function(v) { aa[v]=1; });
  return b.filter(function(v) { return v in aa; });
}

This isn't the very simplest solution (it's more code than filter+indexOf), nor is it the very fastest (probably slower by a constant factor than intersect_safe()), but seems like a pretty good balance. It is on the very simple side, while providing good performance, and it doesn't require pre-sorted inputs.

You can also take a look at PDFMiner (or for older versions of Python see PDFMiner and PDFMiner).

A particular feature of interest in PDFMiner is that you can control how it regroups text parts when extracting them. You do this by specifying the space between lines, words, characters, etc. So, maybe by tweaking this you can achieve what you want (that depends of the variability of your documents). PDFMiner can also give you the location of the text in the page, it can extract data by Object ID and other stuff. So dig in PDFMiner and be creative!

But your problem is really not an easy one to solve because, in a PDF, the text is not continuous, but made from a lot of small groups of characters positioned absolutely in the page. The focus of PDF is to keep the layout intact. It's not content oriented but presentation oriented.

Eclipse 3.6 allows you to turn off formatting by placing a special comment, like

// @formatter:off
...
// @formatter:on

The on/off features have to be turned "on" in Eclipse preferences: Java > Code Style > Formatter. Click on Edit, Off/On Tags, enable Enable Off/On tags.

It's also possible to change the magic strings in the preferences — check out the Eclipse 3.6 docs here.

More Information

Java > Code Style > Formatter > Edit > Off/On Tags

This preference allows you to define one tag to disable and one tag to enable the formatter (see the Off/On Tags tab in your formatter profile):

You also need to enable the flags from Java Formatting

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

You can use the CSS property page-break-before (or page-break-after). Just set page-break-before: always on those block-level elements (e.g., heading, div, p, or table elements) that should start on a new line.

For example, to cause a line break before any 2nd level heading and before any element in class newpage (e.g., <div class=newpage>...), you would use

h2, .newpage { page-break-before: always }

As stated, use TextView.setText(Html.fromHtml(String))

And use these tags in your Html formatted string:

<a href="...">
<b>
<big>
<blockquote>
<br>
<cite>
<dfn>
<div align="...">
<em>
<font size="..." color="..." face="...">

I don't think this is possible. As far as I know, the only time a browser doesn't scroll to a changed document.location.hash is if the hash doesn't exist within the page.

This article isn't directly related to your question, but it discusses typical browser behavior of changing document.location.hash

Yes it is possible to have multiple $(document).ready() calls. However, I don't think you can know in which way they will be executed. (source)

If i understand what you mean, you have to initialize your controller with that style. Something like:

myTVContoller = [[UITableViewController alloc] initWithStyle:UITableViewStyleGrouped];

In Visual Studio 2017, It seems that this behavior is turned off by default. It can be enabled under Tools > Options > Text Editors > C# > Advanced > Outlining > "Collapse #regions when collapsing to definitions"

It may be helpful to some folks.

With the your file opened, go to command window (menu View ? Other Windows ? Command window, or just Ctrl + Alt + A)

Type:

Window.NewWindow

And then

Window.NewVerticalTabGroup

worked for me (Visual Studio 2017).

Or using menus:

Menu Window ? New Window

Menu Window ? New vertical tap group

Here's an approach using tbody elements that could be the way to do it. You can't set the border on a tbody (same as you can't on a tr) but you can set the background colour. If the effect you're wanting to acheive can be obtained with a background colour on the groups of rows instead of a border this will work.

<table cellspacing="0">  
    <tbody>
        <tr>    
            <td>no border</td>    
            <td>no border here either</td>  
        </tr>  
    <tbody bgcolor="gray">
        <tr>    
            <td>one</td>    
            <td>two</td>  
        </tr>  
        <tr>    
            <td>three</td>    
            <td>four</td>  
        </tr>  
    <tbody>
        <tr>    
             <td colspan="2">once again no borders</td>  
        </tr>  
    <tbody bgcolor="gray">
        <tr>    
             <td colspan="2">hello</td>  
        </tr>
    <tbody>
    <tr>    
         <td colspan="2">world</td>  
    </tr>
</table>

@eljenso : intrafest-servlet.xml webapplication context xml will be used if the application uses SPRING WEB MVC.

Otherwise the @kosoant configuration is fine.

Simple example if you dont use SPRING WEB MVC, but want to utitlize SPRING IOC :

In web.xml:

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:application-context.xml</param-value>
</context-param>

Then, your application-context.xml will contain: <import resource="foo-services.xml"/> these import statements to load various application context files and put into main application-context.xml.

Thanks and hope this helps.

1.

$(this).parent().attr("id");

2.

There must be a large number of ways! One could be to hide an element that contains the answer, e.g.

<div>
    Volume = <input type="text" />
    <button type="button">Check answer</button>
    <span style="display: hidden">3.93e-6&lt;/span>
    <div></div>
</div>

And then have similar jQuery code to the above to grab that:

$("button").click(function () 
{
    var correct = Number($(this).parent().children("span").text());
    validate ($(this).siblings("input").val(),correct);
    $(this).siblings("div").html(feedback);
});

bear in mind that if you put the answer in client code then they can see it :) The best way to do this is to validate it server-side, but for an app with limited scope this may not be a problem.

I'll cover each point separately.

1. Some evil code may steal your lock (very popular this one, also has an "accidentally" variant)

   I'm more worried about accidentally. What it amounts to is that this use of this is part of your class' exposed interface, and should be documented. Sometimes the ability of other code to use your lock is desired. This is true of things like Collections.synchronizedMap (see the javadoc).

2. All synchronized methods within the same class use the exact same lock, which reduces throughput

   This is overly simplistic thinking; just getting rid of synchronized(this) won't solve the problem. Proper synchronization for throughput will take more thought.

3. You are (unnecessarily) exposing too much information

   This is a variant of #1. Use of synchronized(this) is part of your interface. If you don't want/need this exposed, don't do it.

If you want to add your own custom animations to UITableView cells, use

[theTableView reloadData];
[theTableView layoutSubviews];
NSArray* visibleViews = [theTableView visibleCells];

to get an array of visible cells. Then add any custom animation to each cell.

Check out this gist I posted for a smooth custom cell animation. https://gist.github.com/floprr/1b7a58e4a18449d962bd

Have you tried adding a configsection handler to your app.config? e.g.

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>

Towards the second half of Create REST API using ASP.NET MVC that speaks both JSON and plain XML, to quote:

Now we need to accept JSON and XML payload, delivered via HTTP POST. Sometimes your client might want to upload a collection of objects in one shot for batch processing. So, they can upload objects using either JSON or XML format. There's no native support in ASP.NET MVC to automatically parse posted JSON or XML and automatically map to Action parameters. So, I wrote a filter that does it."

He then implements an action filter that maps the JSON to C# objects with code shown.

this:

$('#rblDiv input').click(function(){
    alert($('#rblDiv input').index(this));
});

will get you the index of the radio button that was clicked (i think, untested) (note you've had to wrap your RBL in #rblDiv

you could then use that to display the corresponding div like this:

$('.divCollection div:eq(' + $('#rblDiv input').index(this) +')').show();

Is that what you meant?

Edit: Another approach would be to give the rbl a class name, then go:

$('.rblClass').val();

My solution will work if you apply the ActionFilter to the Subcategory action method, as long as you always want to redirect the user to the same bookmark:

http://spikehd.blogspot.com/2012/01/mvc3-redirect-action-to-html-bookmark.html

It modifies the HTML buffer and outputs a small piece of javascript to instruct the browser to append the bookmark.

You could modify the javascript to manually scroll, instead of using a bookmark in the URL, of course!

Hope it helps :)

use can try this:

$('iframe').load( function() {
     $('iframe').contents().find("head")
     .append($("<style type='text/css'>  .my-class{display:none;}  </style>"));
  });

Another option is Apache Commons Config also has a class for loading from INI files. It does have some runtime dependencies, but for INI files it should only require Commons collections, lang, and logging.

I've used Commons Config on projects with their properties and XML configurations. It is very easy to use and supports some pretty powerful features.

This works on SQL Server 2005 (edited to reflect your clarification):

select *
from Things t
where t.ThingID in (
    select top 10 ThingID
    from Things tt
    where tt.Section = t.Section and tt.ThingDate = @Date
    order by tt.DateEntered desc
    )
    and t.ThingDate = @Date
order by Section, DateEntered desc

+1 on James A. Rosen's suggested solution as it has worked well for me, however for completists this site is a fascinating read and the best attempt I've seen in documenting addresses worldwide: http://www.columbia.edu/kermit/postal.html

This happens when your table structure and model class no longer in sync. You need to update the table structure according to the model class or vice versa -- this is when your data is important and must not be deleted. If your data structure has changed and the data isn't important to you, you can use the DropCreateDatabaseIfModelChanges feature (formerly known as 'RecreateDatabaseIfModelChanges' feature) by adding the following code in your Global.asax.cs:

Database.SetInitializer<MyDbContext>(new DropCreateDatabaseIfModelChanges<MyDbContext>());

Run your application again.

As the name implies, this will drop your database and recreate according to your latest model class (or classes) -- provided you believe the table structure definitions in your model classes are the most current and latest; otherwise change the property definitions of your model classes instead.

When you call setBackgoundColor it overwrites/removes any existing background resource, including any borders, corners, padding, etc. What you want to do is change the color of the existing background resource...

View v;
v.getBackground().setColorFilter(Color.parseColor("#00ff00"), PorterDuff.Mode.DARKEN);

Experiment with PorterDuff.Mode.* for different effects.

I use this script. If you change your XML Comments to display as black text on a yellow background you get the effect of highlighting the text you're looking for in the xml column of the results. (Tools -> Options -> Environment -> Fonts and Colors [Display items: XML Comment]

Metrics and Svens answer deals with the usual situation but for us who work in non-english enviroments if you have exotic characters (å,ä,ö) in your character variable you will get the same result, even if you have multiple factor levels.

Levels <- c("Pri", "För") gives the contrast error, while Levels <- c("Pri", "For") doesn't

This is probably a bug.

You should be able to split your string pretty easily, like so:

aString.Split(Environment.NewLine.ToCharArray());

Or

-like '*'+$nameregex+'*'

if you would like to use wildcards.

Git GUI has a PUSH button - pardon the pun, and the dialog box it opens has a checkbox for tags.

I pushed a branch from the command line, without tags, and then tried again pushing the branch using the --follow-tags option descibed above. The option is described as following annotated tags. My tags were simple tags.

I'd fixed something, tagged the commit with the fix in, (so colleagues can cherry pick the fix,) then changed the software version number and tagged the release I created (so colleagues can clone that release).

Git returned saying everything was up-to-date. It did not send the tags! Perhaps because the tags weren't annotated. Perhaps because there was nothing new on the branch.

When I did a similar push with Git GUI, the tags were sent.

For the time being, I am going to be pushing my changes to my remotes with Git GUI and not with the command line and --follow-tags.

Use MadExcept. Or JclDebug.

In the View, modify the current view or create a new view and make a filter change, select the radio button "Show items only when the following is true", in the below columns type "Created" and in the next dropdown select "is less than" and fill the next column [Today]-7.

The keyword [Today] denotes the current day for the calculation and this view will show as per your requirement

You can do this using OPENROWSET as suggested in this answer. Reposting Slogmeister Extrarodinare answer:

Use T-SQL

INSERT INTO OPENROWSET ('Microsoft.ACE.OLEDB.12.0','Text;Database=D:\;HDR=YES;FMT=Delimited','SELECT * FROM [FileName.csv]')
SELECT Field1, Field2, Field3 FROM DatabaseName

But, there are couple of caveats:

1. You need to have the Microsoft.ACE.OLEDB.12.0 provider available. The Jet 4.0 provider will work, too, but it's ancient, so I used this one instead.

2. The .CSV file will have to exist already. If you're using headers (HDR=YES), make sure the first line of the .CSV file is a delimited list of all the fields.

I got this type question on Django, and My issue is forget to add static to the <script> tag.

Such as in my template:

<script  type="text/javascript"  src="css/layer.js"></script>

I should add the static to it like this:

<script type="text/javascript" src="{% static 'css/layer.js' %}" ></script>

No, you need to handle every statement separately..

UPDATE table1
 Statement1;
 UPDATE table 1
 Statement2;

And so on

This would be the shortest way to sum up int type array (for long array LongStream, for double array DoubleStream and so forth). Not all the primitive integer or floating point types have the Stream implementation though.

IntStream.of(integers).sum();

You can use this library from JSON.org to translate your string into a JSON object.

var var1_obj = JSON.parse(var1);

Or you can use the jquery-json library as well.

var var1_obj = $.toJSON(var1);

To sort dictionary, we could make use of operator module. Here is the operator module documentation.

import operator                             #Importing operator module
dc =  {"aa": 3, "bb": 4, "cc": 2, "dd": 1}  #Dictionary to be sorted

dc_sort = sorted(dc.items(),key = operator.itemgetter(1),reverse = True)
print dc_sort

Output sequence will be a sorted list :

[('bb', 4), ('aa', 3), ('cc', 2), ('dd', 1)]

If we want to sort with respect to keys, we can make use of

dc_sort = sorted(dc.items(),key = operator.itemgetter(0),reverse = True)

Output sequence will be :

[('dd', 1), ('cc', 2), ('bb', 4), ('aa', 3)]

Complete checking of a string for null conditions can be a s follows :<\br>

    if(mystring)
     {
       if([mystring isEqualToString:@""])
        {
          mystring=@"some string";
        }
     }    
    else
     {
        //statements
     }

You didn't say which server you're using. In older versions of SQL Server, you can use this:

select top 1 * from mytable order by newid()

In SQL Server 2005 and up, you can use TABLESAMPLE to get a random sample that's repeatable:

SELECT FirstName, LastName
FROM Contact 
TABLESAMPLE (1 ROWS) ;

Class methods are for when you need to have methods that aren't specific to any particular instance, but still involve the class in some way. The most interesting thing about them is that they can be overridden by subclasses, something that's simply not possible in Java's static methods or Python's module-level functions.

If you have a class MyClass, and a module-level function that operates on MyClass (factory, dependency injection stub, etc), make it a classmethod. Then it'll be available to subclasses.

More a comment than an answer - but I cannot add comments yet: Thanks for your help, the count was the easy part. Just for others that might come here. I hope that it will save you some time.

It took me a while to get the attributes from the rows and to understand how to access them from the data() Object (that the data() is an Array and the Attributes can be read by adding them with a dot and not with brackets:

$('#button').click( function () {
    for (var i = 0; i < table.rows('.selected').data().length; i++) { 
       console.log( table.rows('.selected').data()[i].attributeNameFromYourself);
    }
} );

(by the way: I get the data for my table using AJAX and JSON)

You can bind function as follows, instead of init on load

$("div").css("height", $(window).height());
$(?window?).bind("resize",function() {
    $("div").css("height", $(window).height());
});????

0 values of basic types ⁽¹⁾⁽²⁾map to false.

Other values map to true.

This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.

It's a common error to assume that as function return values, false indicates failure. But in particular from main it's false that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.

There's no need to cast to bool for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x, works nicely. One can read !! as a “convert to bool” operator, much as --> can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)

^{1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true. For direct-initialization (8.5), a prvalue of type std::nullptr_t can be converted to a prvalue of type bool; the resulting value is false.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”}

I to use this type of declaration:

const identity: { <T>(arg: T): T } = (arg) => arg;

It allows defining additional props to your function if you ever need to and in some cases, it helps keeping the function body cleaner from the generic definition.

If you don't need the additional props (namespace sort of thing), it can be simplified to:

const identity: <T>(arg: T) => T = (arg) => arg;

In my case multiple wrong attempts locked the account.To do that I had tried running the below query and it worked: ALTER LOGIN WITH PASSWORD= UNLOCK And make sure to set the option "Enforce Password Security" option for specific user to be unchecked by right click on Sql Server -> Properties.

To give a modern approach to this question. This works well, including Ctrl+v. GlobalEventHandlers.oninput.

var onChange = function(evt) {
  console.info(this.value);
  // or
  console.info(evt.target.value);
};
var input = document.getElementById('some-id');
input.addEventListener('input', onChange, false);

import traceback
traceback.print_exc()

When doing this inside an except ...: block it will automatically use the current exception. See http://docs.python.org/library/traceback.html for more information.

time after 30 min, this easiest solution in php

date('Y-m-d H:i:s', strtotime("+30 minutes"));

for DateTime class (PHP 5 >= 5.2.0, PHP 7)

$dateobj = new DateTime();
$dateobj ->modify("+30 minutes"); 

For ASP.NET Core you'll need to spell it out:

@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")

Or you can add a using statement to your view:

@using Microsoft.AspNetCore.Http.Extensions

then

@Context.Request.GetDisplayUrl()

The _ViewImports.cshtml might be a better place for that @using

just use this code in your .m file it will resign the textfield when user tap outside of the textfield.

 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
  [textfield resignFirstResponder];
 }

I got this working by setting the max-height to none, getting the height, re-set the max-height to the calculated height. Works prefectly for me. I got this working for an accordeon menu, with <h5>'s as the toggler expanding the <div> inside the <div>.

JS:

$('h5').click(function(e) {
  $(this).parent('div').addClass('temp_expanded');
  var getheight = ($(this).parent('div').find('div').height());
  $(this).parent('div').removeClass('temp_expanded');
  $(this).parent('div').find('div').css('max-height', getheight);
});

LESS:

div {
> div {
    max-height: 0px;
    overflow: hidden;
    .transition(all 0.3s ease-in-out);
}

&.temp_expanded {
    > div {
        max-height: none;
    }
}

A Unix timestamp is simply the number of seconds since January the first 1970, so to add 24 hours to a Unix timestamp we just add the number of seconds in 24 hours. (24 * 60 *60)

time() + 24*60*60;

Use transparent property

border-color : transparent;

The previous answers are now deprecated, you need to use ContextCompat.getColor to retrieve the color properly:

root.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.white));

Try the UniversalIndentGUI plugin for Notepad++. It re-indents code based on some parameters. It worked well for me.

if you want to custom the error type, a simple thing you can do is to define an error class based on ValueError.

For docker-compose version 2 file format, you can build and tag an image for one service and then use that same built image for another service.

For my case, I want to set up an elasticsearch cluster with 2 nodes, they both need to use the same image, but configured to run differently. I also want to build my own custom elasticsearch image from my own Dockerfile. So this is what I did (docker-compose.yml):

version: '2'

services:
  es-master:
    build: ./elasticsearch
    image: porter/elasticsearch
    ports:
      - "9200:9200"
    container_name: es_master

  es-node:
    image: porter/elasticsearch
    depends_on:
      - es-master
    ports:
      - "9200"
    command: elasticsearch --discovery.zen.ping.unicast.hosts=es_master

You can see that in the first service definition es-master, I use the build option to build an image from the Dockerfile in ./elasticsearch. I tag the image with the name porter/elasticsearch with the image option.
Then, I reference this built image in the es-node service definition with the image option, and also use a depends_on to make sure the other container es-master is built and run first.

The current (as of version 0.20) method for changing column names after a groupby operation is to chain the rename method. See this deprecation note in the documentation for more detail.

Deprecated Answer as of pandas version 0.20

This is the first result in google and although the top answer works it does not really answer the question. There is a better answer here and a long discussion on github about the full functionality of passing dictionaries to the agg method.

These answers unfortunately do not exist in the documentation but the general format for grouping, aggregating and then renaming columns uses a dictionary of dictionaries. The keys to the outer dictionary are column names that are to be aggregated. The inner dictionaries have keys that the new column names with values as the aggregating function.

Before we get there, let's create a four column DataFrame.

df = pd.DataFrame({'A' : list('wwwwxxxx'), 
                   'B':list('yyzzyyzz'), 
                   'C':np.random.rand(8), 
                   'D':np.random.rand(8)})

   A  B         C         D
0  w  y  0.643784  0.828486
1  w  y  0.308682  0.994078
2  w  z  0.518000  0.725663
3  w  z  0.486656  0.259547
4  x  y  0.089913  0.238452
5  x  y  0.688177  0.753107
6  x  z  0.955035  0.462677
7  x  z  0.892066  0.368850

Let's say we want to group by columns A, B and aggregate column C with mean and median and aggregate column D with max. The following code would do this.

df.groupby(['A', 'B']).agg({'C':['mean', 'median'], 'D':'max'})

            D         C          
          max      mean    median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This returns a DataFrame with a hierarchical index. The original question asked about renaming the columns in the same step. This is possible using a dictionary of dictionaries:

df.groupby(['A', 'B']).agg({'C':{'C_mean': 'mean', 'C_median': 'median'}, 
                            'D':{'D_max': 'max'}})

            D         C          
        D_max    C_mean  C_median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This renames the columns all in one go but still leaves the hierarchical index which the top level can be dropped with df.columns = df.columns.droplevel(0).

On Linux, you can use ldconfig, which maintains the ld.so configuration and cache, to print out the directories search by ld.so with

ldconfig -v 2>/dev/null | grep -v ^$'\t'

ldconfig -v prints out the directories search by the linker (without a leading tab) and the shared libraries found in those directories (with a leading tab); the grep gets the directories. On my machine, this line prints out

/usr/lib64/atlas:
/usr/lib/llvm:
/usr/lib64/llvm:
/usr/lib64/mysql:
/usr/lib64/nvidia:
/usr/lib64/tracker-0.12:
/usr/lib/wine:
/usr/lib64/wine:
/usr/lib64/xulrunner-2:
/lib:
/lib64:
/usr/lib:
/usr/lib64:
/usr/lib64/nvidia/tls: (hwcap: 0x8000000000000000)
/lib/i686: (hwcap: 0x0008000000000000)
/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib/sse2: (hwcap: 0x0000000004000000)
/usr/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib64/sse2: (hwcap: 0x0000000004000000)

The first paths, without hwcap in the line, are either built-in or read from /etc/ld.so.conf. The linker can then search additional directories under the basic library search path, with names like sse2 corresponding to additional CPU capabilities. These paths, with hwcap in the line, can contain additional libraries tailored for these CPU capabilities.

One final note: using -p instead of -v above searches the ld.so cache instead.

You can use std::find for this:

#include <algorithm> // for std::find
#include <iterator> // for std::begin, std::end

int main () 
{
  int a[] = {3, 6, 8, 33};
  int x = 8;
  bool exists = std::find(std::begin(a), std::end(a), x) != std::end(a);
}

std::find returns an iterator to the first occurrence of x, or an iterator to one-past the end of the range if x is not found.

"tty" originally meant "teletype" and "pty" means "pseudo-teletype".

In UNIX, /dev/tty* is any device that acts like a "teletype", ie, a terminal. (Called teletype because that's what we had for terminals in those benighted days.)

A pty is a pseudotty, a device entry that acts like a terminal to the process reading and writing there, but is managed by something else. They first appeared (as I recall) for X Window and screen and the like, where you needed something that acted like a terminal but could be used from another program.

Your program is still running. You have to kill it by closing the command line window. If you press control alt delete, task manager, process`s (kill the ones that match your filename).

I have found the above answer to be the best solution, but I don't like the leading space before the percent sign. I have seen somewhat complicated solutions, but I just use this Replace addition to the answer above instead of using other rounding solutions.

String.Format("Value: {0:P2}.", 0.8526).Replace(" %","%") // formats as 85.26% (varies by culture)

Another thing to note is Environment.getExternalStorageDirectory() has been deprecated in API 29, so change this if you're using this to get the database path:

https://developer.android.com/reference/android/os/Environment#getExternalStorageDirectory()

This method was deprecated in API level 29.

To improve user privacy, direct access to shared/external storage devices is deprecated. When an app targets Build.VERSION_CODES.Q, the path returned from this method is no longer directly accessible to apps. Apps can continue to access content stored on shared/external storage by migrating to alternatives such as Context#getExternalFilesDir(String), MediaStore, or Intent#ACTION_OPEN_DOCUMENT.

You could use Timestamp.valueOf(String). The documentation states that it understands timestamps in the format yyyy-mm-dd hh:mm:ss[.f...], so you might need to change the field separators in your incoming string.

Then again, if you're going to do that then you could just parse it yourself and use the setNanos method to store the microseconds.

Yes, it is legal to have a primary key being a foreign key. This is a rare construct, but it applies for:

• a 1:1 relation. The two tables cannot be merged in one because of different permissions and privileges only apply at table level (as of 2017, such a database would be odd).

• a 1:0..1 relation. Profile may or may not exist, depending on the user type.

• performance is an issue, and the design acts as a partition: the profile table is rarely accessed, hosted on a separate disk or has a different sharding policy as compared to the users table. Would not make sense if the underlining storage is columnar.

Dumb question/answer perhaps, but have you tried dd/MM/yyyy? Note the capitalization.

mm is for minutes with a leading zero. So I doubt that's what you want.

{"a":"\u00e1"} and {"a":"á"} are different ways to write the same JSON document; The JSON decoder will decode the unicode escape.

In php 5.4+, php's json_encode does have the JSON_UNESCAPED_UNICODE option for plain output. On older php versions, you can roll out your own JSON encoder that does not encode non-ASCII characters, or use Pear's JSON encoder and remove line 349 to 433.

Check out my answer in this similar question:

python: urllib2 how to send cookie with urlopen request

import urllib2
import urllib
from cookielib import CookieJar

cj = CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
# input-type values from the html form
formdata = { "username" : username, "password": password, "form-id" : "1234" }
data_encoded = urllib.urlencode(formdata)
response = opener.open("https://page.com/login.php", data_encoded)
content = response.read()

EDIT:

I see I've gotten a few downvotes for my answer, but no explaining comments. I'm guessing it's because I'm referring to the urllib libraries instead of requests. I do that because the OP asks for help with requests or for someone to suggest another approach.

I have had the same problem. I am using windows 7 and this should also work for windows 8. The services responsible for the TNS listener and database were stopped when I looked in the Task Manager.

1: Hit Ctrl-Alt-Del and select "Start Task Manager".

From there go to the "Services" tab.

There are 5 services that need to be running for the database to be accessed correctly.

In the list below "databasename" is the database name you assigned during creation without the quotes.

I am also using database 11g, if you are using another type those fields would be different below. the * after home is the home install, if you have more than 1 database there would be home1, and home2

These are the 5 services

1. OracleVssWriter"databasename"
2. OracleService"databasename"
3. OracleOraDb11g_home*TNSListener
4. OracleOraDb11g_home*ClrAgent
5. OracleDBConsole"databasename"

If any of these services are stopped right click on them and start them. After they have all started go back into SQL developer and re-try the connection and it should work.

There's also ShortGuid - A shorter and url friendly GUID class in C#. It's available as a Nuget. More information here.

PM> Install-Package CSharpVitamins.ShortGuid

Usage:

Guid guid = Guid.NewGuid();
ShortGuid sguid1 = guid; // implicitly cast the guid as a shortguid
Console.WriteLine(sguid1);
Console.WriteLine(sguid1.Guid);

This produces a new guid, uses that guid to create a ShortGuid, and displays the two equivalent values in the console. Results would be something along the lines of:

ShortGuid: FEx1sZbSD0ugmgMAF_RGHw 
Guid:      b1754c14-d296-4b0f-a09a-030017f4461f

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

• Overview of the New C++ (C++11/14) (PDF only) (Scott Meyers) (updated for C++14) These are the presentation materials (slides and some lecture notes) of a three-day training course offered by Scott Meyers, who's a highly respected author on C++. Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• The C++ Super-FAQ (Marshall Cline, Bjarne Stroustrup and others) is an effort by the Standard C++ Foundation to unify the C++ FAQs previously maintained individually by Marshall Cline and Bjarne Stroustrup and also incorporating new contributions. The items mostly address issues at an intermediate level and are often written with a humorous tone. Not all items might be fully up to date with the latest edition of the C++ standard yet.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

Fellas, I know this is old but hey I've this solution which I think works better than all. First and foremost overcomes the Case Sensitivity that the jquery :contains() is shipped with:

var text = "text";

var search = $( "ul li label" ).filter( function ()
{
    return $( this ).text().toLowerCase().indexOf( text.toLowerCase() ) >= 0;
}).first(); // Returns the first element that matches the text. You can return the last one with .last()

Hope someone in the near future finds it helpful.

Faster way to create folder:

if (!is_dir('path/to/directory')) {
    mkdir('path/to/directory', 0777, true);
}

The solution provided by ebeneditos works perfectly.

But if you have cv2.imwrite() in several sections of a large code snippet and you want to change the path where the images get saved, you will have to change the path at every occurrence of cv2.imwrite() individually.

As Soltius stated, here is a better way. Declare a path and pass it as a string into cv2.imwrite()

import cv2
import os
img = cv2.imread('1.jpg', 1)
path = 'D:/OpenCV/Scripts/Images'
cv2.imwrite(os.path.join(path , 'waka.jpg'), img)
cv2.waitKey(0)

Now if you want to modify the path, you just have to change the path variable.

Helpful method I created a while ago...

private static double round (double value, int precision) {
    int scale = (int) Math.pow(10, precision);
    return (double) Math.round(value * scale) / scale;
}

.format is a more readable way to handle variable formatting:

'{:.{prec}f}'.format(26.034, prec=2)

To get min/max value in array, you can use:

var _array = [1,3,2];
Math.max.apply(Math,_array); // 3
Math.min.apply(Math,_array); // 1

I see that there are a god-zillion answers already but I don't see any practical solutions. Of course this is a real problem and there is no good reason for excluding this syntax in Java. Since the original question lacks a context where this may be need, I provide both a context and a solution:

Suppose you have a static method in a bunch of classes that are identical. These methods call a static method that is class specific:

class C1 {
    static void doWork() {
        ...
        for (int k: list)
            doMoreWork(k);
        ...
    }
    private static void doMoreWork(int k) {
        // code specific to class C1
    }
}
class C2 {
    static void doWork() {
        ...
        for (int k: list)
            doMoreWork(k);
        ...
    }
    private static void doMoreWork(int k) {
        // code specific to class C2
    }
}

doWork() methods in C1 and C2 are identical. There may be a lot of these calsses: C3 C4 etc. If static abstract was allowed, you'd eliminate the duplicate code by doing something like:

abstract class C {
    static void doWork() {
        ...
        for (int k: list)
            doMoreWork(k);
        ...
    }

    static abstract void doMoreWork(int k);
}

class C1 extends C {
    private static void doMoreWork(int k) {
        // code for class C1
    }
}

class C2 extends C {
    private static void doMoreWork(int k) {
        // code for class C2
    }
}

but this would not compile because static abstract combination is not allowed. However, this can be circumvented with static class construct, which is allowed:

abstract class C {
    void doWork() {
        ...
        for (int k: list)
            doMoreWork(k);
        ...
    }
    abstract void doMoreWork(int k);
}
class C1 {
    private static final C c = new  C(){  
        @Override void doMoreWork(int k) {
            System.out.println("code for C1");
        }
    };
    public static void doWork() {
        c.doWork();
    }
}
class C2 {
    private static final C c = new C() {
        @Override void doMoreWork(int k) {
            System.out.println("code for C2");
        }
    };
    public static void doWork() {
        c.doWork();
    }
}

With this solution the only code that is duplicated is

    public static void doWork() {
        c.doWork();
    }

I think the reason those suggesting using the C:\PROGRA~1 name have received downvotes is because those names are seen as a legacy feature of Windows best forgotten, which may also be unstable, at least between different installations, although probably not on the same machine.

Also, as someone pointed out in a comment to another answer, Windows can be configured not to have the 8.3 legacy names in the filesystem at all.

I just wrote a directive to handle this, so you can simply add the attribute bs-active-link to the parent <ul> element, and any time the route changed, it will find the matching link, and add the active class to the corresponding <li>.

You can see it in action here: http://jsfiddle.net/8mcedv3b/

Example HTML:

<ul class="nav navbar-nav" bs-active-link>
  <li><a href="/home">Home</a></li>
  <li><a href="/contact">Contact</a></li>
</ul>

Javascript:

angular.module('appName')
.directive('bsActiveLink', ['$location', function ($location) {
return {
    restrict: 'A', //use as attribute 
    replace: false,
    link: function (scope, elem) {
        //after the route has changed
        scope.$on("$routeChangeSuccess", function () {
            var hrefs = ['/#' + $location.path(),
                         '#' + $location.path(), //html5: false
                         $location.path()]; //html5: true
            angular.forEach(elem.find('a'), function (a) {
                a = angular.element(a);
                if (-1 !== hrefs.indexOf(a.attr('href'))) {
                    a.parent().addClass('active');
                } else {
                    a.parent().removeClass('active');   
                };
            });     
        });
    }
}
}]);

Better way by using on() with chaining like,

$(document).ready(function(){
    $(".header").on('click',function(){
        $(this).children(".children").toggle();
    }).on('click','a',function(e) {
        e.stopPropagation();
   });
});

The comment by @xicocaio should be highlighted.

tkinter is python version-specific in the sense that sudo apt-get install python3-tk will install tkinter exclusively for your default version of python. Suppose you have different python versions within various virtual environments, you will have to install tkinter for the desired python version used in that virtual environment. For example, sudo apt-get install python3.7-tk. Not doing this will still lead to No module named ' tkinter' errors, even after installing it for the global python version.

Since we have a virtual address space of 2^32 and each page size is 2^12, we can store (2^32/2^12) = 2^20 pages. Since each entry into this page table has an address of size 4 bytes, then we have 2^20*4 = 4MB. So the page table takes up 4MB in memory.

There is both window.onbeforeunload and window.onunload, which are used differently depending on the browser. You can assign them either by setting the window properties to functions, or using the .addEventListener:

window.onbeforeunload = function(){
   // Do something
}
// OR
window.addEventListener("beforeunload", function(e){
   // Do something
}, false);
   

Usually, onbeforeunload is used if you need to stop the user from leaving the page (ex. the user is working on some unsaved data, so he/she should save before leaving). onunload isn't supported by Opera, as far as I know, but you could always set both.

Small additional note to @rmag's answer. If you have empty but required fields that you want to make dirty use this:

$scope.myForm.username.$setViewValue($scope.myForm.username.$viewValue !== undefined 
    ? $scope.myForm.username.$viewValue : '');

to highlight word without moving cursor, plop

" highlight reg. ex. in @/ register
set hlsearch
" remap `*`/`#` to search forwards/backwards (resp.)
" w/o moving cursor
nnoremap <silent> * :execute "normal! *N"<cr>
nnoremap <silent> # :execute "normal! #n"<cr>

into your vimrc.

What's nice about this is g* and g# will still work like "normal" * and #.

To set hlsearch off, you can use "short-form" (unless you have another function that starts with "noh" in command mode): :noh. Or you can use long version: :nohlsearch

For extreme convenience (I find myself toggling hlsearch maybe 20 times per day), you can map something to toggle hlsearch like so:

" search highlight toggle
nnoremap <silent> <leader>st :set hlsearch!<cr>

.:. if your <leader> is \ (it is by default), you can press \st (quickly) in normal mode to toggle hlsearch.

Or maybe you just want to have :noh mapped:

" search clear
nnoremap <silent> <leader>sc :nohlsearch<cr>

The above simply runs :nohlsearch so (unlike :set hlsearch!) it will still highlight word next time you press * or # in normal mode.

cheers

Cast the result as TIME and the result will be in time format for duration of the interval.

select CAST(job_end - job_start) AS TIME(0)) from tableA

You can use string.scan(your_regex).flatten. If your regex contains groups, it will return in a single plain array.

string = "A 54mpl3 string w1th 7 numbers scatter3r ar0und"
your_regex = /(\d+)[m-t]/
string.scan(your_regex).flatten
=> ["54", "1", "3"]

Regex can be a named group as well.

string = 'group_photo.jpg'
regex = /\A(?<name>.*)\.(?<ext>.*)\z/
string.scan(regex).flatten

You can also use gsub, it's just one more way if you want MatchData.

str.gsub(/\d/).map{ Regexp.last_match }

The Apache project has a library called POI which can be used to generate MS Office files. It is a Java library but the advantage is that it can run on Linux with no trouble. This library has its limitations but it may do the job for you, and it's probably simpler to use than trying to run Word.

Another option would be OpenOffice but I can't exactly recommend it since I've never used it.

Try to not use setInterval.
You can resend request to server after successful response with timeout.
jQuery:

sendRequest(); //call function

function sendRequest(){
    $.ajax({
        url: "test.php",
        success: 
        function(result){
            $('#links').text(result); //insert text of test.php into your div
            setTimeout(function(){
                sendRequest(); //this will send request again and again;
            }, 5000);
        }
    });
}

Mohammed Radwan, Your solution is elegant. To detect iframe clicks in Firefox and IE, you can use a simple method with document.activeElement and a timer, however... I have searched all over the interwebs for a method to detect clicks on an iframe in Chrome and Safari. At the brink of giving up, I find your answer. Thank you, sir!

Some tips: I have found your solution to be more reliable when calling the init() function directly, rather than through attachOnloadEvent(). Of course to do that, you must call init() only after the iframe html. So it would look something like:

<script>
var isOverIFrame = false;
function processMouseOut() {
    isOverIFrame = false;
    top.focus();
}
function processMouseOver() { isOverIFrame = true; }
function processIFrameClick() {
    if(isOverIFrame) {
    //was clicked
    }
}

function init() {
    var element = document.getElementsByTagName("iframe");
    for (var i=0; i<element.length; i++) {
        element[i].onmouseover = processMouseOver;
        element[i].onmouseout = processMouseOut;
    }
    if (typeof window.attachEvent != 'undefined') {
        top.attachEvent('onblur', processIFrameClick);
    }
    else if (typeof window.addEventListener != 'undefined') {
        top.addEventListener('blur', processIFrameClick, false);
    }
}
</script>

<iframe src="http://google.com"></iframe>

<script>init();</script>

Following solution can be pretty useful in the usual login / main activity scenario or implementing a blocking screen.

To minimize the app rather than going back to previous activity, you can override onBackPressed() like this:

@Override
public void onBackPressed() {
    moveTaskToBack(true);
}

moveTaskToBack(boolean nonRoot) leaves your back stack as it is, just puts your task (all activities) in background. Same as if user pressed Home button.

Parameter boolean nonRoot - If false then this only works if the activity is the root of a task; if true it will work for any activity in a task.

On .Net 4.0:

System.Net.WebUtility.HtmlDecode()

No need to include assembly for a C# project

I haven't tried it from a WebRequest, but both the Windows Media Player ActiveX and the MediaElement (from WPF) components are capable of playing and buffering MP3 streams.

I use it to play data coming from a SHOUTcast stream and it worked great. However, I'm not sure if it will work in the scenario you propose.

Just found out that IE stops supporting trim(), probably after a recent windows update. If you use dojo, you can use dojo.string.trim(), it works cross platform.

This is actually a fairly interesting question. It's not as simple as it looks at first. For reference, I'm going to be basing this off of the latest C11 language grammar defined in N1570

I guess the counter-intuitive part of the question is: if this is correct C:

if (a == 1) {
  int b = 10;
}

then why is this not also correct C?

if (a == 1)
  int b = 10;

I mean, a one-line conditional if statement should be fine either with or without braces, right?

The answer lies in the grammar of the if statement, as defined by the C standard. The relevant parts of the grammar I've quoted below. Succinctly: the int b = 10 line is a declaration, not a statement, and the grammar for the if statement requires a statement after the conditional that it's testing. But if you enclose the declaration in braces, it becomes a statement and everything's well.

And just for the sake of answering the question completely -- this has nothing to do with scope. The b variable that exists inside that scope will be inaccessible from outside of it, but the program is still syntactically correct. Strictly speaking, the compiler shouldn't throw an error on it. Of course, you should be building with -Wall -Werror anyways ;-)

There isn't a system feature to change the height of the table based upon the contents of the tableview. Having said that, it is possible to programmatically change the height of the tableview based upon the contents, specifically based upon the contentSize of the tableview (which is easier than manually calculating the height yourself). A few of the particulars vary depending upon whether you're using the new autolayout that's part of iOS 6, or not.

But assuming you're configuring your table view's underlying model in viewDidLoad, if you want to then adjust the height of the tableview, you can do this in viewDidAppear:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [self adjustHeightOfTableview];
}

Likewise, if you ever perform a reloadData (or otherwise add or remove rows) for a tableview, you'd want to make sure that you also manually call adjustHeightOfTableView there, too, e.g.:

- (IBAction)onPressButton:(id)sender
{
    [self buildModel];
    [self.tableView reloadData];

    [self adjustHeightOfTableview];
}

So the question is what should our adjustHeightOfTableview do. Unfortunately, this is a function of whether you use the iOS 6 autolayout or not. You can determine if you have autolayout turned on by opening your storyboard or NIB and go to the "File Inspector" (e.g. press option+command+1 or click on that first tab on the panel on the right):

Let's assume for a second that autolayout was off. In that case, it's quite simple and adjustHeightOfTableview would just adjust the frame of the tableview:

- (void)adjustHeightOfTableview
{
    CGFloat height = self.tableView.contentSize.height;
    CGFloat maxHeight = self.tableView.superview.frame.size.height - self.tableView.frame.origin.y;

    // if the height of the content is greater than the maxHeight of
    // total space on the screen, limit the height to the size of the
    // superview.

    if (height > maxHeight)
        height = maxHeight;

    // now set the frame accordingly

    [UIView animateWithDuration:0.25 animations:^{
        CGRect frame = self.tableView.frame;
        frame.size.height = height;
        self.tableView.frame = frame;

        // if you have other controls that should be resized/moved to accommodate
        // the resized tableview, do that here, too
    }];
}

If your autolayout was on, though, adjustHeightOfTableview would adjust a height constraint for your tableview:

- (void)adjustHeightOfTableview
{
    CGFloat height = self.tableView.contentSize.height;
    CGFloat maxHeight = self.tableView.superview.frame.size.height - self.tableView.frame.origin.y;

    // if the height of the content is greater than the maxHeight of
    // total space on the screen, limit the height to the size of the
    // superview.

    if (height > maxHeight)
        height = maxHeight;

    // now set the height constraint accordingly

    [UIView animateWithDuration:0.25 animations:^{
        self.tableViewHeightConstraint.constant = height;
        [self.view setNeedsUpdateConstraints];
    }];
}

For this latter constraint-based solution to work with autolayout, we must take care of a few things first:

1. Make sure your tableview has a height constraint by clicking on the center button in the group of buttons here and then choose to add the height constraint:

   

2. Then add an IBOutlet for that constraint:

   

3. Make sure you adjust other constraints so they don't conflict if you adjust the size tableview programmatically. In my example, the tableview had a trailing space constraint that locked it to the bottom of the screen, so I had to adjust that constraint so that rather than being locked at a particular size, it could be greater or equal to a value, and with a lower priority, so that the height and top of the tableview would rule the day:

   

   What you do here with other constraints will depend entirely upon what other controls you have on your screen below the tableview. As always, dealing with constraints is a little awkward, but it definitely works, though the specifics in your situation depend entirely upon what else you have on the scene. But hopefully you get the idea. Bottom line, with autolayout, make sure to adjust your other constraints (if any) to be flexible to account for the changing tableview height.

As you can see, it's much easier to programmatically adjust the height of a tableview if you're not using autolayout, but in case you are, I present both alternatives.

It’s not really answering your question, but just on this part:

[3] requires both an id and a name... having both is somewhat redundant

You’ll most likely need to have an id attribute on each form field anyway, so that you can associate its <label> element with it, like this:

<label for="foo">Foo:</label>
<input type="text" name="foo" id="foo" />

This is required for accessibility (i.e. if you don’t associate form labels and controls, why do you hate blind people so much?).

It is somewhat redundant, although less so when you have checkboxes/radio buttons, where several of them can share a name. Ultimately, id and name are for different purposes, even if both are often set to the same value.

Having trouble wrapping my head around this.

Have a rewrite rule with four conditions.
The first three conditions A, B, C are to be AND which is then OR with D

RewriteCond A       true
RewriteCond B       false
RewriteCond C [OR]  true
RewriteCond D       true
RewriteRule ...

But that seems to be an expression of A and B and (C or D) = false (don't rewrite)

How can I get to the desired expression? (A and B and C) or D = true (rewrite)

Preferably without using the additional steps of setting environment variables.

HELP!!!

I've tried everything but nothing worked, but this did. If you can debug on local IIS instead of Express, change the configurations as shown in the image below. Do not forget to click on "Create virtual directory"

Another scenario, again for the benefit of people searching.

For me this error occurred during the Dispose() method which masked a previous error unrelated to encryption.

Once the other component was fixed, this exception went away.

Wildcards aren't expanded inside quoted strings. And when wildcard is expanded, it's returned unchanged if there are no matches, it doesn't expand into an empty string. Try:

output="$(ls home/edward/bank1/fiche/Test* 2>/dev/null)"
if [ -n "$output" ]
then echo "Found one"
else echo "Found none"
fi

If the wildcard expanded to filenames, ls will list them on stdout; otherwise it will print an error on stderr, and nothing on stdout. The contents of stdout are assigned to output.

if [ -n "$output" ] tests whether $output contains anything.

Another way to write this would be:

if [ $(ls home/edward/bank1/fiche/Test* 2>/dev/null | wc -l) -gt 0 ]

For UNIX:

As Stephen C has suggested, changing the maximum file descriptor value to a higher value avoids this problem.

Try looking at your present file descriptor capacity:

   $ ulimit -n

Then change the limit according to your requirements.

   $ ulimit -n <value>

Note that this just changes the limits in the current shell and any child / descendant process. To make the change "stick" you need to put it into the relevant shell script or initialization file.

Just had the similar error when installing java 8 (jdk & jre) on a system already running Java 7.

Error: Registry key 'Software\JavaSoft\Java Runtime

Environment'\CurrentVersion' has value '1.8', but '1.7' is required.

Error: could not find java.dll Error: Could not find Java SE Runtime Environment.

My environment was set up correctly (Path & java_home correctly defined), but the problem arises from the way pre-8 Java installers worked, which is that they used to copy the three executables (java.exe, javaw.exe & javaws.exe) to the Windows system directory. These remain unless overwritten by a new pre-8 installation.

However the Java 8 installer instead creates symbolic links in a new directory, C:\ProgramData\Oracle\Java\javapath, pointing to the actual JRE 8 location.

This means that you'll actually run the old 7 exes but use the new 8 DLLs.

So, the solution is simply to delete the 3 Java exes, as above, from the windows system directory.

If you are running 32-bit Java on a 64-bit Windows, the exes would be in Windows\SysWOW64, otherwise in Windows\System32.

Here is the focus listener example.

editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean hasFocus) {
        if (hasFocus) {
            Toast.makeText(getApplicationContext(), "Got the focus", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(getApplicationContext(), "Lost the focus", Toast.LENGTH_LONG).show();
        }
    }
});

Worked this out, turns out that android.R.color.black is not the same as Color.BLACK. Changed the code to:

Paint paint = new Paint(); 
paint.setColor(Color.WHITE); 
paint.setStyle(Style.FILL); 
canvas.drawPaint(paint); 

paint.setColor(Color.BLACK); 
paint.setTextSize(20); 
canvas.drawText("Some Text", 10, 25, paint); 

and it all works fine now!!

Take a look at this http://benalman.com/code/projects/jquery-resize/examples/resize/

It has various examples. Try resizing your window and see how elements inside container elements adjusted.

Example with js fiddle to explain how to get it work.
Take a look at this fiddle http://jsfiddle.net/sgsqJ/4/

In that resize() event is bound to an elements having class "test" and also to the window object and in resize callback of window object $('.test').resize() is called.

e.g.

$('#test_div').bind('resize', function(){
            console.log('resized');
});

$(window).resize(function(){
   $('#test_div').resize();
});

for .NET Core console apps you can do this 2 ways - from the launchsettings.json or the properties menu.

Launchsettings.json

or right click the project > properties > debug tab on left

see "Application Arguments:"

• this is " " (space) delimited, no need for any commas. just start typing. each space " " will represent a new input parameter.
• (whatever changes you make here will be reflected in the launchsettings.json file...)

In relative layout you need specify textview height:

android:layout_height="100dp"

Or specify lines attribute:

android:lines="3"

My App.config looks as below:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
</configuration>

I noticed that there is localDB in the path that you mentioned above and has the version v11.0. So I entered (LocalDB\V11.0) in Add Connection dialogue and it worked for me.

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories, and it should work.

The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

To change color of SVG element I have found out a way while inspecting Google search box search icon below:

.search_icon {
  color: red;
  fill: currentColor;
  display: inline-block;
  width: 100px;
  height: 100px;
}

<span class="search_icon">
    <svg focusable="false" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M15.5 14h-.79l-.28-.27A6.471 6.471 0 0 0 16 9.5 6.5 6.5 0 1 0 9.5 16c1.61 0 3.09-.59 4.23-1.57l.27.28v.79l5 4.99L20.49 19l-4.99-5zm-6 0C7.01 14 5 11.99 5 9.5S7.01 5 9.5 5 14 7.01 14 9.5 11.99 14 9.5 14z"></path></svg>
</span>

I have used span element with "display:inline-block", height, width and setting a particular style "color: red; fill: currentColor;" to that span tag which is inherited by the child svg element.

Suppose you have following lines of code

MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)

If you are receiving following error message

AttributeError: module 'urllib' has no attribute 'urlretrieve'

Then you should try following code to fix the issue:

import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)

test -z returns true if the parameter is empty (see man sh or man test).

You can create an inline view or a temporary table, fill it with you values and issue this:

SELECT  *
FROM    fiberbox f
JOIN    (
        SELECT '%1740%' AS cond
        UNION ALL
        SELECT '%1938%' AS cond
        UNION ALL
        SELECT '%1940%' AS cond
        ) ?
ON      f.fiberBox LIKE cond

This, however, can return you multiple rows for a fiberbox that is something like '1740, 1938', so this query can fit you better:

SELECT  *
FROM    fiberbox f
WHERE   EXISTS
        (
        SELECT  1
        FROM    (
                SELECT '%1740%' AS cond
                UNION ALL
                SELECT '%1938%' AS cond
                UNION ALL
                SELECT '%1940%' AS cond
                ) ?
        WHERE   f.fiberbox LIKE cond
        )

I got this error:

System.Net.Sockets.SocketException: An attempt was made to access a socket in a way forbidden by its access permissions

when the port was used by another program.

int value = 1;
string description = Enumerations.GetEnumDescription((MyEnum)value);

The default underlying data type for an enum in C# is an int, you can just cast it.

I always liked this (you could modify as appropriate):

public static IEnumerable<TEnum> GetEnumValues()
{
  Type enumType = typeof(TEnum);

  if(!enumType.IsEnum)
    throw new ArgumentException("Type argument must be Enum type");

  Array enumValues = Enum.GetValues(enumType);
  return enumValues.Cast<TEnum>();
}

You can use the following nginx configuration example:

upstream adminhost {
  server adminhostname:8080;
}

server {
  listen 80;

  location ~ ^/admin/(.*)$ {
    proxy_pass http://adminhost/$1$is_args$args;
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $server_name;
  }
}

find . -name '*.ear' -exec ls -lh {} \;

You can copy this to your eclipse.ini file to have 1024M:

-clean -showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Xms512m
-Xmx1024m
-XX:PermSize=128m
-XX:MaxPermSize=256m 

It took me a while to figure out the solution to this problem - it's in the original question. You need to have a script that calls tsc in your package.json file so that you can run:

npm run tsc 

Include -- before you pass in options (or just include them in the script):

npm run tsc -- -v

Here's an example package.json:

{
  "name": "foo",
  "scripts": {
    "tsc": "tsc"
  },
  "dependencies": {
    "typescript": "^1.8.10"
  }
}

You probably want pop:

a = ['a', 'b', 'c', 'd']
a.pop(1)

# now a is ['a', 'c', 'd']

By default, pop without any arguments removes the last item:

a = ['a', 'b', 'c', 'd']
a.pop()

# now a is ['a', 'b', 'c']

You can also use onBackPressed by following ways using customized Toast:

enter image description here

    android:background="@drawable/curve_edittext"/>

    if (doubleBackToExitPressedOnce) {
        android.os.Process.killProcess(Process.myPid());
        System.exit(1);
        return;
    }

    this.doubleBackToExitPressedOnce = true;
    Toast toast = new Toast(Dashboard.this);
    View view = getLayoutInflater().inflate(R.layout.toast_view,null);
    toast.setView(view);
    toast.setDuration(Toast.LENGTH_SHORT);
    int margin = getResources().getDimensionPixelSize(R.dimen.toast_vertical_margin);
    toast.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL, 0, margin);
    toast.show();

    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            doubleBackToExitPressedOnce=false;
        }
    }, 2000);
}

    editAction.backgroundColor = .blue

    let deleteAction = UITableViewRowAction(style: .normal, title: "Delete") { (rowAction, indexPath) in
        //TODO: Delete the row at indexPath here

    return [editAction,deleteAction]
}

For a one-liner, like migrating a database you can use --dbname followed by a connection string (including the password) as stated in the pg_dump manual

In essence.

pg_dump --dbname=postgresql://username:[email protected]:5432/mydatabase

Note: Make sure that you use the option --dbname instead of the shorter -d and use a valid URI prefix, postgresql:// or postgres://.

The general URI form is:

postgresql://[user[:password]@][netloc][:port][/dbname][?param1=value1&...]

Best practice in your case (repetitive task in cron) this shouldn't be done because of security issues. If it weren't for .pgpass file I would save the connection string as an environment variable.

export MYDB=postgresql://username:[email protected]:5432/mydatabase

then have in your crontab

0 3 * * * pg_dump --dbname=$MYDB | gzip > ~/backup/db/$(date +%Y-%m-%d).psql.gz

Make sure you're doing this for a good reason, a simple function like the following would allow static typing and allows your IDE to do things like "Find References" and Refactor -> Rename.

public Task <T> factory (String name)
{
  Task <T> result;

  if (name.CompareTo ("A") == 0)
  {
    result = new TaskA ();
  }
  else if (name.CompareTo ("B") == 0)
  {
    result = new TaskB ();
  }

  return result;
}

You can make a new SVN repository. Export your Git project (fleshing out the .git files). Add it to the SVN repository (initializing the repository with what you had so far in Git). Then use the instructions for importing SVN repositories in a fresh Git project.

But this will lose your previous Git history.

You can also use something like

<c:if test="${ testObject.testPropert == "testValue" }">...</c:if>

$.ajax({
        url: 'mail3.php',
        type: 'POST',
        data: 'contactName=' + name + '&contactEmail=' + email + '&spam=' + spam,

        success: function(result) {

            //console.log(result);
            $('#results,#errors').remove();
            $('#contactWrapper').append('<p id="results">' + result + '</p>');
            $('#loading').fadeOut(500, function() {
                $(this).remove();

            });

            if(result === "no_errors") location.href = "http://www.example.com/ThankYou.html"

        }
    });

Just add this top of your controller.

use DB;

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

$conn=new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
    // If this is your connection then you have to assign null
    // to your connection variable as follows:
$conn=null;
    // By this way you can close connection in PDO.

CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(1);

See Here for more details.

Or

DateTime dt = DateTime.Now;
Console.WriteLine( dt.ToString( "MMMM" ) );

Or if you want to get the culture-specific abbreviated name.

GetAbbreviatedMonthName(1);

I have a similar case. I need to install openssl via brew and then use pip to install mitmproxy. I get the same complaint from brew link --force. Following is the solution I reached: (without force link by brew)

LDFLAGS=-L/usr/local/opt/openssl/lib 
CPPFLAGS=-I/usr/local/opt/openssl/include
PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig 
pip install mitmproxy

This does not address the question straightforwardly. I leave the one-liner in case anyone uses pip and requires the openssl lib.

Note: the /usr/local/opt/openssl/lib paths are obtained by brew info openssl

Since Horse is a subclass of Animal, you can just change

print(Animal.SIZES[1])

with

print(self.SIZES[1])

Still, you need to remember that SIZES[1] means "big", so probably you could improve your code by doing something like:

class Animal:
    SIZE_HUGE="Huge"
    SIZE_BIG="Big"
    SIZE_MEDIUM="Medium"
    SIZE_SMALL="Small"

class Horse(Animal):
    def printSize(self):
        print(self.SIZE_BIG)

Alternatively, you could create intermediate classes: HugeAnimal, BigAnimal, and so on. That would be especially helpful if each animal class will contain different logic.

If lftp is installed on your machine, use mirror dir. And you are done. See the comment by Ciro below if you want to recursively download a directory.

I assume you don't want leading/trailing space. This means you have to split the regex into "first character", "stuff in the middle" and "last character":

^[a-zA-Z0-9_][a-zA-Z0-9_ ]*[a-zA-Z0-9_]$

or if you use a perl-like syntax:

^\w[\w ]*\w$

Also: If you intentionally worded your regex that it also allows empty Strings, you have to make the entire thing optional:

^(\w[\w ]*\w)?$

If you want to only allow single space chars, it looks a bit different:

^((\w+ )*\w+)?$

This matches 0..n words followed by a single space, plus one word without space. And makes the entire thing optional to allow empty strings.

You can do it with the HTMLWorker class (deprecated) like this:

import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter.getInstance(document, file);
    document.open();
    HTMLWorker htmlWorker = new HTMLWorker(document);
    htmlWorker.parse(new StringReader(k));
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

or using the XMLWorker, (download from this jar) using this code:

import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(k.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

I have been working with Titanium for over a week now and feel like I have a good feel about its weakness.

1) If you hoping you use the same code on multiple platforms good luck! You'll see something like backgroundGradient and be amazed until you find out android version doesn't support it. Then have to revert to using a gradient image, might as well use it for both versions to make the code easier right?

2) A lot of weird behaviors, on the Titanium android sdk you need to understand what a "heavy" window is just to get the back button to work, or even better orientation event tracking. This isn't how the android platform really is, its just how Titanium tries to make their API work.

3) Your thrown in the dark, Things will crash and you have to start to comment code and then when you find it, never use it. There are certain obvious bugs, like orientation and percents on android that have been a problem for over six months.

4) Bugs .... there are a lot of bugs and they will be reported, sit around for months, get fixed in a few days. I am surprised they even are planning to release a black berry mobile sdk when there are so many other problems with android.

5) Titanium Iphone versus Titanium Android javascript engines are completely different. On android version you can download remote javascript files, include and use libraries like mootools, jquery and so on. I was in heaven when I found this out because I didn't have to keep compiling my android app. The android apk installation process takes so long! Iphone none of that is possible, also the iphone version has a much faster javascript engine.

If you stay away from a lot of the native UI parts, i.e instead use setInterval to detect orientation changes, sticking with gradient images, forget about the back button, build your own animations, forget window header, toolbars, and dashboard. You really can make an api that works on both that doesn't require of lot of rewriting. But at that points its just as sluggish as a webapp.

So is it worth it? After all the pain, its worth every minute. You can abstract the logic and just build different UI for each rather then if elseing everywhere. Titanium lets you make fluid applications, that feel fast. You lose the powerful layout abilities of each platform but if you think simple, things can get done under a single language.

Why not a web app? On entry level market android phones its horribly slow to generate a webview and consumes a lot of memory you could be using to do more complex logic.

Each statement has a distinct use case. They are not interchangeable.

SELECT...INTO MyTable... creates a new MyTable where one did not exist before.

INSERT INTO MyTable...SELECT... is used when MyTable already exists.

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

One think you should change is the call $state.go(). As described here:

• $state.go(to [, toParams] [, options])

The param passed should be the state name

$scope.create = function() {
  // instead of this
  //$state.go("/tab/newpost"); 

  // we should use this
  $state.go("tab.newpost"); 
};

Some cite from doc (the first parameter to of the [$state.go(to \[, toParams\] \[, options\]):

to

String Absolute State Name or Relative State Path

The name of the state that will be transitioned to or a relative state path. If the path starts with ^ or . then it is relative, otherwise it is absolute.

Some examples:

$state.go('contact.detail') will go to the 'contact.detail' state
$state.go('^') will go to a parent state.
$state.go('^.sibling') will go to a sibling state.
$state.go('.child.grandchild') will go to a grandchild state.

Buttons like <button>Click to do something</button> are submit buttons.

Set type="button" to change that. type="submit" is the default (as specified by the HTML recommendation).

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

Reference: https://pypi.org/project/chromedriver-binary/

Cheesle is right. There's no way for the classloader to find the embedded jars. If you put enough debug commands on the command line you should be able to see the 'java' command failing to add the jars to a classpath

What you want to make is sometimes called an 'uberjar'. I found one-jar as a tool to help make them, but I haven't tried it. Sure there's many other approaches.

innerHTML is fine and still valid. Use it all the time on projects big and small. I just flipped to an open tab in my IDE and there was one right there.

 document.getElementById("data-progress").innerHTML = "<img src='../images/loading.gif'/>";

Not much has changed in js + dom manipulation since 2005, other than the addition of more libraries. You can easily set other properties such as

   uploadElement.style.width = "100%";

These are the preferred methods:

var item = Items.SingleOrDefault(x => x.Id == 123);

Or

var item = Items.Single(x => x.Id == 123);

I can see at least three options:

1.

df[:10]

2. Using head

df.head(10)

For negative values of n, this function returns all rows except the last n rows, equivalent to df[:-n] [Source].

3. Using iloc

df.iloc[:10]

If-elseif-else can be written as a nested if-else. These are (logically speaking) equivalent:

if (A) 
{
    doA();
}
else if (B)
{
    doB();
}
else if (C)
{
    doC();
}
else
{
    doX();
}

is the same as:

if (A) 
{
    doA();
}
else
{
    if (B)
    {
        doB();
    }
    else
    {
         if (C)
         {
             doC();
         }
         else
         {
             doX();
         }
    }
}

The result is that ultimately only one of doA, doB, doC, or doX will be evaluated.

Before I get to my reiterated answer; I am confessing that the only answer I would accept here is this one by KM. above. I down voted the other answers because none of them actually answered the question asked or they were not adequate. PRINT output does indeed show up in the Message window, but that is not what was asked at all.

Why doesn't the PRINT statement output show during my Stored Procedure execution?
The short version of this answer is that you are sending your sproc's execution over to the SQL server and it isn't going to respond until it is finished with the whole transaction. Here is a better answer located at this external link.

• For even more opinions/observations focus your attention on this SO post here.
• Specifically look at this answer of the same post by Phil_factor (Ha ha! Love the SQL humor)
• Regarding the suggestion of using RAISERROR WITH NOWAIT look at this answer of the same post by JimCarden

Don't do these things

1. Some people are under the impression that they can just use a GO statement after their PRINT statement, but you CANNOT use the GO statement INSIDE of a sproc. So that solution is out.
2. I don't recommend SELECT-ing your print statements because it is just going to muddy your result set with nonsense and if your sproc is supposed to be consumed by a program later, then you will have to know which result sets to skip when looping through the results from your data reader. This is just a bad idea, so don't do it.
3. Another problem with SELECT-ING your print statements is that they don't always show up immediately. I have had different experiences with this for different executions, so don't expect any kind of consistency with this methodology.

Alternative to PRINT inside of a Stored Procedure
Really this is kind of an icky work around in my opinion because the syntax is confusing in the context that it is being used in, but who knows maybe it will be updated in the future by Microsoft. I just don't like the idea of raising an error for the sole purpose of printing out debug info...

It seems like the only way around this issue is to use, as has been explained numerous times already RAISERROR WITH NOWAIT. I am providing an example and pointing out a small problem with this approach:

ALTER
--CREATE 
    PROCEDURE [dbo].[PrintVsRaiseErrorSprocExample]
AS
BEGIN
    SET NOCOUNT ON;

    -- This will print immediately
    RAISERROR ('RE Start', 0, 1) WITH NOWAIT
    SELECT 1;

    -- Five second delay to simulate lengthy execution
    WAITFOR DELAY '00:00:05'

    -- This will print after the five second delay
    RAISERROR ('RE End', 0, 1) WITH NOWAIT
    SELECT 2;
END

GO

EXEC [dbo].[PrintVsRaiseErrorSprocExample]

Both SELECT statement results will only show after the execution is finished and the print statements will show in the order shown above.

Potential problem with this approach
Let's say you have both your PRINT statement and RAISERROR statement one after the other, then they both print. I'm sure this has something to do with buffering, but just be aware that this can happen.

ALTER
--CREATE 
    PROCEDURE [dbo].[PrintVsRaiseErrorSprocExample2]
AS
BEGIN
    SET NOCOUNT ON;

    -- Both the PRINT and RAISERROR statements will show
    PRINT 'P Start';
    RAISERROR ('RE Start', 0, 1) WITH NOWAIT
    SELECT 1;

    WAITFOR DELAY '00:00:05'

    -- Both the PRINT and RAISERROR statements will show
    PRINT 'P End'
    RAISERROR ('RE End', 0, 1) WITH NOWAIT
    SELECT 2;
END

GO

EXEC [dbo].[PrintVsRaiseErrorSprocExample2]

Therefore the work around here is, don't use both PRINT and RAISERROR, just choose one over the other. If you want your output to show during the execution of a sproc then use RAISERROR WITH NOWAIT.

Have a look at this sample:

public class A {
  //statements
}

public class B extends A {
  public void foo() { }
}

A a=new B();

//To execute **foo()** method.

((B)a).foo();

If you know the package name, then this works without using a try-catch block or iterating through a bunch of packages:

public static boolean isPackageInstalled(Context context, String packageName) {
    final PackageManager packageManager = context.getPackageManager();
    Intent intent = packageManager.getLaunchIntentForPackage(packageName);
    if (intent == null) {
        return false;
    }
    List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    return !list.isEmpty();
}

The rubocop gem contributors propose in their Ruby Style Guide:

Prefer alias when aliasing methods in lexical class scope as the resolution of self in this context is also lexical, and it communicates clearly to the user that the indirection of your alias will not be altered at runtime or by any subclass unless made explicit.

class Westerner
  def first_name
   @names.first
  end

 alias given_name first_name
end

Always use alias_method when aliasing methods of modules, classes, or singleton classes at runtime, as the lexical scope of alias leads to unpredictability in these cases

module Mononymous
  def self.included(other)
    other.class_eval { alias_method :full_name, :given_name }
  end
end

class Sting < Westerner
  include Mononymous
end

From MDSN article, Controlling Transactions (Database Engine).

If a run-time statement error (such as a constraint violation) occurs in a batch, the default behavior in the Database Engine is to roll back only the statement that generated the error. You can change this behavior using the SET XACT_ABORT statement. After SET XACT_ABORT ON is executed, any run-time statement error causes an automatic rollback of the current transaction. Compile errors, such as syntax errors, are not affected by SET XACT_ABORT. For more information, see SET XACT_ABORT (Transact-SQL).

In your case it will rollback the complete transaction when any of inserts fail.

The "tiresome way" is standard SQL and how mainstream RDBMS do it.

With a 100+ columns, you mostly likely have a design problem... also, there are mitigating methods in client tools (eg generation UPDATE statements) or by using ORMs

Step To Use AutoMapper with ASP.NET Core.

Step 1. Installing AutoMapper.Extensions.Microsoft.DependencyInjection from NuGet Package.

Step 2. Create a Folder in Solution to keep Mappings with Name "Mappings".

Step 3. After adding Mapping folder we have added a class with Name "MappingProfile" this name can anything unique and good to understand.

In this class, we are going to Maintain all Mappings.

Step 4. Initializing Mapper in Startup "ConfigureServices"

In Startup Class, we Need to Initialize Profile which we have created and also Register AutoMapper Service.

  Mapper.Initialize(cfg => cfg.AddProfile<MappingProfile>());

  services.AddAutoMapper();

Code Snippet to show ConfigureServices Method where we need to Initialize and Register AutoMapper.

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }


    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });


        // Start Registering and Initializing AutoMapper

        Mapper.Initialize(cfg => cfg.AddProfile<MappingProfile>());
        services.AddAutoMapper();

        // End Registering and Initializing AutoMapper

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

    }}

Step 5. Get Output.

To Get Mapped result we need to call AutoMapper.Mapper.Map and pass Proper Destination and Source.

AutoMapper.Mapper.Map<Destination>(source);

CodeSnippet

    [HttpPost]
    public void Post([FromBody] SchemeMasterViewModel schemeMaster)
    {
        if (ModelState.IsValid)
        {
            var mappedresult = AutoMapper.Mapper.Map<SchemeMaster>(schemeMaster);
        }
    }

It should be like this.

In your Component

computed: {
        ...mapGetters({
                nameFromStore: 'name'
            }),
        name: {
           get(){
             return this.nameFromStore
           },
           set(newName){
             return newName
           } 
        }
    }

In your store

export const store = new Vuex.Store({
         state:{
             name : "Stackoverflow"
         },
         getters: {
                 name: (state) => {
                     return state.name;
                 }
         }
}

GO is like the end of a script.

You could have multiple CREATE TABLE statements, separated by GO. It's a way of isolating one part of the script from another, but submitting it all in one block.

BEGIN and END are just like { and } in C/++/#, Java, etc.

They bound a logical block of code. I tend to use BEGIN and END at the start and end of a stored procedure, but it's not strictly necessary there. Where it IS necessary is for loops, and IF statements, etc, where you need more then one step...

IF EXISTS (SELECT * FROM my_table WHERE id = @id)
BEGIN
   INSERT INTO Log SELECT @id, 'deleted'
   DELETE my_table WHERE id = @id
END

First, get the correct opencv version extension which you want to install. If you want to install 3.4.9.20 then run pip install opencv-python==3.4.5.20.

Here is a way to do it without adding an ID to the form elements.

<form method="post">
    ...
    <select name="List">
        <option value="1">Test1</option>
        <option value="2">Test2</option>
    </select>
    <select name="List">
        <option value="3">Test3</option>
        <option value="4">Test4</option>
    </select>
    ...
</form>

public ActionResult OrderProcessor()
{
    string[] ids = Request.Form.GetValues("List");
}

Then ids will contain all the selected option values from the select lists. Also, you could go down the Model Binder route like so:

public class OrderModel
{
    public string[] List { get; set; }
}

public ActionResult OrderProcessor(OrderModel model)
{
    string[] ids = model.List;
}

Hope this helps.

If I understand what you need, try this:

SELECT id, pass, AVG(val) AS val_1 
FROM data_r1 
GROUP BY id, pass;

Or, if you want just one row for every id, this:

SELECT d1.id,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 1) as val_1,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 2) as val_2,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 3) as val_3,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 4) as val_4,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 5) as val_5,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 6) as val_6,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 7) as val_7
from data_r1 d1
GROUP BY d1.id

SELECT * from `user` ORDER BY `user_id`; 

SET @count = 0;

UPDATE `user`  SET `user_id` = @count:= @count + 1;

ALTER TABLE `user_id` AUTO_INCREMENT = 1;

if you want to order by

A bit old question but I found myself needing this also and that the suggestions above were inaduquate - and as such - developed a thin wrapper myself: https://github.com/hofmeister/MatchIt

global $DB;
$status = $DB->query("UPDATE exp_members SET group_id = '$group_id' WHERE member_id = '$member_id'");

if($status == false)
{ 
    die("Didn't Update"); 
}

If you are using mysql_query in the backend (whatever $DB->query() uses to query the database), it will return a TRUE or FALSE for INSERT, UPDATE, and DELETE (and a few others), commands, based on their status.

Just Simply Use

if (System.IO.Directory.Exists(path))
{
    ...
}

Another possibility is using java.nio.ByteBuffer.

Something like

ByteBuffer bb = ByteBuffer.allocate(a.length + b.length + c.length);
bb.put(a);
bb.put(b);
bb.put(c);
byte[] result = bb.array();

// or using method chaining:

byte[] result = ByteBuffer
        .allocate(a.length + b.length + c.length)
        .put(a).put(b).put(c)
        .array();

Note that the array must be appropriately sized to start with, so the allocation line is required (as array() simply returns the backing array, without taking the offset, position or limit into account).

This is probably what you're looking for:

select * from TABLE where COLUMN regexp '[^ -~]';

It should return all rows where COLUMN contains non-ASCII characters (or non-printable ASCII characters such as newline).

You can absolutely do this. Write-Output has a flag called "NoEnumerate" that is essentially the same thing.

preventDefault is a widespread standard; using an adhoc every time you want to be compliant with old IE versions is cumbersome, better to use a polyfill:

if (typeof Event.prototype.preventDefault === 'undefined') {
    Event.prototype.preventDefault = function (e, callback) {
        this.returnValue = false;
    };
}

This will modify the prototype of the Event and add this function, a great feature of javascript/DOM in general. Now you can use e.preventDefault with no problem.

The gist is that the foreign method uses ALTER_TABLE to make a pre-existing field into a foreign key. So you have to define the table type before you apply the foreign key. However, it doesn't have to be in a separate Schema:: call. You can do both within create, like this:

public function up()
{
    Schema::create('priorities', function($table) {
        $table->increments('id', true);
        $table->integer('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->string('priority_name');
        $table->smallInteger('rank');
        $table->text('class');
        $table->timestamps('timecreated');
    });
}

Also note that the type of user_id is set to unsigned to match the foreign key.

Short answer: using as.data.frame.matrix(mytable), as @Victor Van Hee suggested.

Long answer: as.data.frame(mytable) may not work on contingency tables generated by table() function, even if is.matrix(your_table) returns TRUE. It will still melt you table into the factor1 factor2 factori counts format.

Example:

> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)

> freq_t
   gear
cyl  3  4  5

I'm arriving a bit late to the party, but I've got three four five:

1. If you poll InvokeRequired on a control that hasn't been loaded/shown, it will say false - and blow up in your face if you try to change it from another thread (the solution is to reference this.Handle in the creator of the control).

2. Another one which tripped me up is that given an assembly with:

   enum MyEnum
   {
       Red,
       Blue,
   }
   

   if you calculate MyEnum.Red.ToString() in another assembly, and in between times someone has recompiled your enum to:

   enum MyEnum
   {
       Black,
       Red,
       Blue,
   }
   

   at runtime, you will get "Black".

3. I had a shared assembly with some handy constants in. My predecessor had left a load of ugly-looking get-only properties, I thought I'd get rid of the clutter and just use public const. I was more than a little surprised when VS compiled them to their values, and not references.

4. If you implement a new method of an interface from another assembly, but you rebuild referencing the old version of that assembly, you get a TypeLoadException (no implementation of 'NewMethod'), even though you have implemented it (see here).

5. Dictionary<,>: "The order in which the items are returned is undefined". This is horrible, because it can bite you sometimes, but work others, and if you've just blindly assumed that Dictionary is going to play nice ("why shouldn't it? I thought, List does"), you really have to have your nose in it before you finally start to question your assumption.

<div style="text-align:center">
    <span>Short text</span><br />
    <span>This is long text</span>
</div>

I'm late to the party, but I had this same issue working with Java 8.

This is what worked for me, on the HttpServletRequest request object.

request.getHeader("origin");

and

request.getHeader("referer");

How I came to that conclusion:

I have a java app running on http://localhost:3000 making a Http Post to another java app I have running on http://localhost:8080.

From the Java code running on http://localhost:8080 I couldn't get the http://localhost:3000 from the HttpServletRequest using the answers above. For me using the getHeader method with the correct string input worked.

request.getHeader("origin") gave me "http://localhost:3000" which is what I wanted.

request.getHeader("referer") gave me "http://localhost:3000/xxxx" where xxxx is full URL I have from the requesting app.

For Ubuntu i use this:

(exec PROG_SH &> /dev/null &)

bar "$@" will be equivalent to bar "$1" "$2" "$3" "$4"

Notice that the quotation marks are important!

"$@", $@, "$*" or $* will each behave slightly different regarding escaping and concatenation as described in this stackoverflow answer.

One closely related use case is passing all given arguments inside an argument like this:

bash -c "bar \"$1\" \"$2\" \"$3\" \"$4\"".

I use a variation of @kvantour's answer to achieve this:

bash -c "bar $(printf -- '"%s" ' "$@")"

UPDATE 2

@Override
    protected void onResume() {
        super.onResume();
        mUserNameEdit.requestFocus();

        mUserNameEdit.postDelayed(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                InputMethodManager keyboard = (InputMethodManager)
                getSystemService(Context.INPUT_METHOD_SERVICE);
                keyboard.showSoftInput(mUserNameEdit, 0);
            }
        },200); //use 300 to make it run when coming back from lock screen
    }

I tried very hard and found out a solution ... whenever a new activity starts then keyboard cant open but we can use Runnable in onResume and it is working fine so please try this code and check...

UPDATE 1

add this line in your AppLogin.java

mUserNameEdit.requestFocus();

and this line in your AppList.java

listview.requestFocus()'

after this check your application if it is not working then add this line in your AndroidManifest.xml file

<activity android:name=".AppLogin" android:configChanges="keyboardHidden|orientation"></activity>
<activity android:name=".AppList" android:configChanges="keyboard|orientation"></activity>

ORIGINAL ANSWER

 InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);

for hide keyboard

 imm.hideSoftInputFromWindow(ed.getWindowToken(), 0); 

for show keyboard

 imm.showSoftInput(ed, 0);

for focus on EditText

 ed.requestFocus();

where ed is EditText

This answer only uses Duration methods and works with Java 8 :

public static String format(Duration d) {
    long days = d.toDays();
    d = d.minusDays(days);
    long hours = d.toHours();
    d = d.minusHours(hours);
    long minutes = d.toMinutes();
    d = d.minusMinutes(minutes);
    long seconds = d.getSeconds() ;
    return 
            (days ==  0?"":days+" jours,")+ 
            (hours == 0?"":hours+" heures,")+ 
            (minutes ==  0?"":minutes+" minutes,")+ 
            (seconds == 0?"":seconds+" secondes,");
}

I had the same problem and it was due to the end of line. I had copied from another document. I put everythng on the same line, then split them again and it worked.

To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:

rpm -qa | grep mariadb

then remove the mariadb packages using (changing to your versions):

rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"

Delete left over files and folders (which also removes any databases):

rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql

Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.

There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL

Try setting the charset on your Content-Type:

httpCon.setRequestProperty( "Content-Type", "multipart/form-data; charset=UTF-8; boundary=" + boundary );

$(window).unbind('scroll');

Even though the documentation says it will remove all event handlers if called with no arguments, it is worth giving a try explicitly unbinding it.

Update

It worked if you used single quotes? That doesn't sound right - as far as I know, JavaScript treats single and double quotes the same (unlike some other languages like PHP and C).

Simplest of all solutions:

filtered_df = df[df['var2'].isnull()]

This filters and gives you rows which has only NaN values in 'var2' column.

It was giving 415 Http response Code as error,

So I added

httppost.addHeader("Content-Type", "text/xml; charset=utf-8");

Everything alright now, Http: 200

In my experience JSON.stringify is slightly faster than util.inspect. I had to save the result object of a DB2 query as a json file, The query returned an object of 92k rows, the conversion took very long to complete with util.inspect, so I did the following test by writing the same 1000 record object to a file with both methods.

1. JSON.Stringify

   fs.writeFile('./data.json', JSON.stringify(obj, null, 2));
   

Time: 3:57 (3 min 57 sec)

Result's format:

[
  {
    "PROB": "00001",
    "BO": "AXZ",
    "CNTRY": "649"
   },
  ...
]

2. util.inspect

   var util = require('util');
   fs.writeFile('./data.json', util.inspect(obj, false, 2, false));
   

Time: 4:12 (4 min 12 sec)

Result's format:

[ { PROB: '00001',
    BO: 'AXZ',
    CNTRY: '649' },
    ...
]

Example to create an array of a custom class

Below is the class definition.

public class DummyUser
{
    public string email { get; set; }
    public string language { get; set; }
}

This is how you can initialize the array:

private DummyUser[] arrDummyUser = new DummyUser[]
{
    new DummyUser{
       email = "[email protected]",
       language = "English"
    },
    new DummyUser{
       email = "[email protected]",
       language = "Spanish"
    }
};

1 Checking for positive value

In javascript simple comparison like: value >== 0 does not provide us with answer due to existence of -0 and +0 (This is concept has it roots in derivative equations) Bellow example of those values and its properties:

var negativeZero = -0;
var negativeZero = -1 / Number.POSITIVE_INFINITY;
var negativeZero = -Number.MIN_VALUE / Number.POSITIVE_INFINITY;

var positiveZero = 0;
var positiveZero = 1 / Number.POSITIVE_INFINITY;
var positiveZero = Number.MIN_VALUE / Number.POSITIVE_INFINITY;

-0 === +0                     // true
1 / -0                        // -Infinity
+0 / -0                       // NaN
-0 * Number.POSITIVE_INFINITY // NaN

Having that in mind we can write function like bellow to check for sign of given number:

function isPositive (number) {
    if ( number > 0 ) { 
        return true;
    }
    if (number < 0) {
        return false;
    }
    if ( 1 / number === Number.POSITIVE_INFINITY ) {
        return true;
    }
    return false;
}

2a Checking for number being an Integer (in mathematical sense)

To check that number is an integer we can use bellow function:

function isInteger (number) {
    return parseInt(number) === number;
}
//* in ECMA Script 6 use Number.isInteger

2b Checking for number being an Integer (in computer science)

In this case we are checking that number does not have any exponential part (please note that in JS numbers are represented in double-precision floating-point format) However in javascript it is more usable to check that value is "safe integer" (http://people.mozilla.org/~jorendorff/es6-draft.html#sec-number.max_safe_integer) - to put it simple it means that we can add/substract 1 to "safe integer" and be sure that result will be same as expected from math lessons. To illustrate what I mean, result of some unsafe operations bellow:

Number.MAX_SAFE_INTEGER + 1 === Number.MAX_SAFE_INTEGER + 2;          // true
Number.MAX_SAFE_INTEGER * 2 + 1 === Number.MAX_SAFE_INTEGER * 2 + 4;  // true

Ok, so to check that number is safe integer we can use Number.MAX_SAFE_INTEGER / Number.MIN_SAFE_INTEGER and parseInt to ensure that number is integer at all.

function isSafeInteger (number) {
    return parseInt(number) === number
    && number <== Number.MAX_SAFE_INTEGER
    && number >== Number.MIN_SAFE_INTEGER
}
//* in ECMA Script 6 use Number.isSafeInteger

I had all my settings covered in the accepted answer. The problem I had was that I was trying to update the Entity Framework entity type "Task" like:

public IHttpActionResult Post(Task task)

What worked for me was to create my own entity "DTOTask" like:

public IHttpActionResult Post(DTOTask task)

The ScrollTo() function doesn't work anymore. This is what I used and it worked fine.

driver.execute_script("document.getElementById('mydiv').scrollIntoView();")

Some thing in the similar vein, I would add one other step.

Note that on npm version > 1.4.9, 'npm install' does install devDependencies. First try removing existing modules and cache:

remove node_modules $ rm -rf node_modules/
run $ npm cache clean

Then try:

npm install --dev
npm update --dev

This at least will resolve the recursive dependency resolution.

If we want output like 'string0123456789' then we can use map function and join method of string.

>>> 'string'+"".join(map(str,xrange(10)))
'string0123456789'

If we want List of string values then use list comprehension method.

>>> ['string'+i for i in map(str,xrange(10))]
['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9']

Note:

Use xrange() for Python 2.x

USe range() for Python 3.x

Use OrderedDicts: http://docs.python.org/2/library/collections.html#collections.OrderedDict

>>> x = OrderedDict((("a", "1"), ("c", '3'), ("b", "2")))
>>> x["d"] = 4
>>> x.keys().index("d")
3
>>> x.keys().index("c")
1

For those using Python 3

>>> list(x.keys()).index("c")
1

In case you are here looking for a fast string concatenation method in Python, then you do not need a special StringBuilder class. Simple concatenation works just as well without the performance penalty seen in C#.

resultString = ""

resultString += "Append 1"
resultString += "Append 2"

See Antoine-tran's answer for performance results

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

works for me from Pardeep Jain

The problem with all of the answers given so far is that on the something borrowed site, the Mac bar remains totally hidden when scrolling up, and the provided answers don't accomplish that.

If you just use scrollTo and then the user later scrolls up, the nav bar is revealed again, so it seems you have to put the whole site inside of a div and force scrolling to happen inside of that div rather than on the body which keeps the nav bar hidden during scrolling in any direction.

You can, however, still reveal the nav bar by touching near the top of the screen on apple devices.

  private Toast mToastToShow;
  public void showToast(View view) {
 // Set the toast and duration
 int toastDurationInMilliSeconds = 10000;
 mToastToShow = Toast.makeText(this, "Hello world, I am a toast.",  Toast.LENGTH_LONG);

 // Set the countdown to display the toast
 CountDownTimer toastCountDown;
 toastCountDown = new CountDownTimer(toastDurationInMilliSeconds, 1000 /*Tick duration*/) {
  public void onTick(long millisUntilFinished) {
     mToastToShow.show();
  }
  public void onFinish() {
     mToastToShow.cancel();
     }
    };

    // Show the toast and starts the countdown
     mToastToShow.show();
     toastCountDown.start();
      }

The following is the right method

$(document).ready(function() {
    $('#btnSun').click(function(){
        $(this).myFunction();
     });
     $.fn.myFunction = function() { 
        alert('hi'); 
     }
});

You shouldn't just turn off verification. Rather you should download a certificate bundle, perhaps the curl bundle will do?

Then you just need to put it on your web server, giving the user that runs php permission to read the file. Then this code should work for you:

$arrContextOptions= [
    'ssl' => [
        'cafile' => '/path/to/bundle/cacert.pem',
        'verify_peer'=> true,
        'verify_peer_name'=> true,
    ],
];

$response = file_get_contents(
    'https://maps.co.weber.ut.us/arcgis/rest/services/SDE_composite_locator/GeocodeServer/findAddressCandidates?Street=&SingleLine=3042+N+1050+W&outFields=*&outSR=102100&searchExtent=&f=json',
    false,
    stream_context_create($arrContextOptions)
);

Hopefully, the root certificate of the site you are trying to access is in the curl bundle. If it isn't, this still won't work until you get the root certificate of the site and put it into your certificate file.

I'd probably use an ImageIcon and set it on a JLabel which I'd add to the JPanel.

Here's Sun's docs on the subject matter.

It sounds like you have a form tag in a Master Page and in the Page that is throwing the error.

You can have only one.

If updating cURL doesn't fix it, updating NSS should do the trick.

X * 2 = 1 bit shift left
X / 2 = 1 bit shift right
X * 3 = shift left 1 bit and then add X

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

Another nice and efficient approach - is to pass rows for insertion as 1 argument, which is array of json objects.

E.g. you passing argument:

[ {id: 18, score: 1}, { id: 19, score: 5} ]

It is array, which may contain any amount of objects inside. Then your SQL looks like:

INSERT INTO links (parent_id, child_id, score) 
SELECT 123, (r->>'id')::int, (r->>'score')::int 
FROM unnest($1::json[]) as r 

Notice: Your postgress must be new enough, to support json

If git pull does not help, then probably you have pushed your changes (A) and after that had used git commit --amend to add some more changes (B). Therefore, git thinks that you can lose the history - it interprets B as a different commit despite it contains all changes from A.

             B
            /
        ---X---A

If nobody changes the repo after A, then you can do git push --force.

However, if there are changes after A from other person:

             B
            /
        ---X---A---C

then you must rebase that persons changes from A to B (C->D).

             B---D
            /
        ---X---A---C

or fix the problem manually. I didn't think how to do that yet.

Actually, for the latest JBOSS 7 AS, we need a .dodeploy marker even for archives. So add a marker to trigger the deployment.

In my case, I added a Hello.war.deployed file in the same directory and then everything worked fine.

Hope this helps someone!

FWIW and though I'm no Python guru I got by with this

>>> class TextParser(HTMLParser):
...    def handle_starttag(self, tag, attrs):
...        if tag == "b":
...            self.all_data.append("bold")
...        else:
...            self.all_data.append("other")
...     
...         
>>> p = TextParser()
>>> p.all_data = []
>>> p.feed(text)
>>> print p.all_data
(...)

Just got me the parse results back as needed.

I would be tempted to use grepl, which should give all the lines with matches and can be generalised for arbitrary strings.

[Edit] However, as pointed out in the comments, this will capture much more than the string 1578 (e.g. it also matches for 21578 etc) and thus should be used only if you are certain that you the length of the values you are searching will not be larger than the four characters or digits shown here.

And subsetting as per the other answer also works fine:

mydata_2[mydata_2$height_seca1 == 1578, ]

If you're looking for several different values, you could put them in a vector and then use the %in% operator:

look.for <- c(1578, 1658, 1616)

   sex age height_seca1 height_chad1 height_DL weight_alog1

You can use a manual sorting algorithm like this

public void ListItemSorter(object sender, ColumnClickEventArgs e)
    {
        ListView list = (ListView)sender;
        int total = list.Items.Count;
        list.BeginUpdate();
        ListViewItem[] items = new ListViewItem[total];
        for (int i = 0; i < total; i++)
        {
            int count = list.Items.Count;
            int minIdx = 0;
            for (int j = 1; j < count; j++)
                if (list.Items[j].SubItems[e.Column].Text.CompareTo(list.Items[minIdx].SubItems[e.Column].Text) < 0)
                    minIdx = j;
            items[i] = list.Items[minIdx];
            list.Items.RemoveAt(minIdx);
        }
        list.Items.AddRange(items);
        list.EndUpdate();
    }

this method uses selection sort in O^2 order and as Ascending. You can change the '>' with '<' for a descending or add an argument for this method. It sorts any column that is clicked and works perfect for small amount of data.

First you add the Navigation back button

   getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);

Then, add the Method in your HostActivity.

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId()==android.R.id.home)
    {
        super.onBackPressed();
        Toast.makeText(this, "OnBAckPressed Works", Toast.LENGTH_SHORT).show();
    }

    return super.onOptionsItemSelected(item);
}

Try this, definitely work.

There is no standard C++ way to do this without resorting to C-style varargs (...).

There are of course default arguments that sort of "look" like variable number of arguments depending on the context:

void myfunc( int i = 0, int j = 1, int k = 2 );

// other code...

myfunc();
myfunc( 2 );
myfunc( 2, 1 );
myfunc( 2, 1, 0 );

All four function calls call myfunc with varying number of arguments. If none are given, the default arguments are used. Note however, that you can only omit trailing arguments. There is no way, for example to omit i and give only j.

This is an adaptation to the accepted answer, but I couldn't get what I needed from the answer, and had to test this worked as it was a hunch, so i'm putting my solution up here.

We needed to verify a local file existed, and only allow the file (a PDF) to open if it existed. If you omit the URL of the website, the browser will automatically determine the host name - making it work in localhost and on the server:

$.ajax({

    url: 'YourFolderOnWebsite/' + SomeDynamicVariable + '.pdf',
    type: 'HEAD',
    error: function () {
        //file not exists
        alert('PDF does not exist');

    },
    success: function () {
        //file exists
        window.open('YourFolderOnWebsite/' + SomeDynamicVariable + '.pdf', "_blank", "fullscreen=yes");

    }
});

Modify your Jquery in following way:

$.ajax({
            url: someurl,
            contentType: 'application/json',
            data: JSONObject,
            headers: { 'Access-Control-Allow-Origin': '*' }, //add this line
            dataType: 'json',
            type: 'POST',                
            success: function (Data) {....}
});

This should do the trick:

date.Subtract(new DateTime(1970, 1,1)).TotalMilliseconds
