Programs & Examples On #Jsonschema

JSON Schema is not intended to be feature equivalent with XML Schema. There are features in one but not in the other.

In general you can create a mapping from XML to JSON and back again, but that is not the case for XML schema and JSON schema.

That said, if you have mapped a XML file to JSON, it is quite possible to craft an JSON Schema that validates that JSON in nearly the same way that the XSD validates the XML. But it isn't a direct mapping. And it is not possible to guarantee that it will validate the JSON exactly the same as the XSD validates the XML.

For this reason, and unless the two specs are made to be 100% feature compatible, migrating a validation system from XML/XSD to JSON/JSON Schema will require human intervention.

There are a lot of tools mentioned, but one more called JSON Schema inferencer for the record:

(it's not a library or a product, but a Python script)

I had a similar problem getting scrollTop to work after reload of div content. The content scrolled to top each time the procedure below was run. I found that a little delay before setting the new scrolltop solved the issue.

This is cut from wdCalendar where I modified this procedure:

 function BuildDaysAndWeekView(startday, l, events, config)
   ....
        var scrollpos = $("#dvtec").scrollTop();
        gridcontainer.html(html.join(""));
        setTimeout(function() {
            $("#dvtec").scrollTop(scrollpos);
        }, 25);
   ....

Without the delay, it simply did not work.

Goto window+R and type services.msc and press enter.

Then start SQL server manually if not automatically started.

Then you try to login, it must be works.

The data series names are defined by the column headers. Add the names to the column headers that you would like to use as titles for each of your data series, select all of the data (including the headers), then re-generate your graph. The names in the headers should then appear as the names in the legend for each series.

The following constructor, JLabel(String, int), allow you to specify the horizontal alignment of the label.

JLabel label = new JLabel("The Label", SwingConstants.CENTER);

The problem is in your pod files deployment target iOS Version not in your project deployment target iOS Version, so you need to change the deployment iOS version for your pods as well to anything higher than 8.0 to do so open your project workspace and do this:

1- Click on pods.

2- Select each project and target and click on build settings.

3- Under Deployment section change the iOS Deployment Target version to anything more than 8.0 (better to try the same project version).

4- Repeat this for every other project in your pods then run the app.

Docker for Mac I want to connect from a container to a service on the host

The host has a changing IP address (or none if you have no network access). From 18.03 onwards our recommendation is to connect to the special DNS name host.docker.internal, which resolves to the internal IP address used by the host.

The gateway is also reachable as gateway.docker.internal. https://docs.docker.com/docker-for-mac/networking/#use-cases-and-workarounds

This error could also be because you are not subscribing to the Observable.

Example, instead of:

this.products = this.productService.getProducts();

do this:

   this.productService.getProducts().subscribe({
    next: products=>this.products = products,
    error: err=>this.errorMessage = err
   });

You can add 'debugger' in your code and reload the app, which puts the breakpoint there and you can 'step over' , or run.

var service = {
user_id: null,
getCurrentUser: function() {
  debugger; // Set the debugger inside 
            // this function
  return service.user_id;
}

Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!

If you're asking how to click a link via jQuery then assuming you have markup which looks like:

<a id="my-link" href="/relative/path.html">Click Me!</a>

You could click() it by executing:

$('#my-link').click();

public class SomeClass
{
    public void SomeMethod()
    {
        StackFrame frame = new StackFrame(1);
        var method = frame.GetMethod();
        var type = method.DeclaringType;
        var name = method.Name;
    }
}

Now let's say you have another class like this:

public class Caller
{
   public void Call()
   {
      SomeClass s = new SomeClass();
      s.SomeMethod();
   }
}

name will be "Call" and type will be "Caller"

UPDATE Two years later since I'm still getting upvotes on this

In .Net 4.5 there is now a much easier way to do this. You can take advantage of the CallerMemberNameAttribute

Going with the previous example:

public class SomeClass
{
    public void SomeMethod([CallerMemberName]string memberName = "")
    {
        Console.WriteLine(memberName); //output will be name of calling method
    }
}

Here is the complete procedure for IDEA IntelliJ 2019.3:

1. File > Project Structure

2. Under Project Settings > Modules

3. Under 'Sources' tab, right-click on 'src' folder and select 'Sources'.

4. Apply changes.

On EF6.2, you can use HasIndex() to add indexes for migration through fluent API.

https://github.com/aspnet/EntityFramework6/issues/274

Example

modelBuilder
    .Entity<User>()
    .HasIndex(u => u.Email)
        .IsUnique();

On EF6.1 onwards, you can use IndexAnnotation() to add indexes for migration in your fluent API.

http://msdn.microsoft.com/en-us/data/jj591617.aspx#PropertyIndex

You must add reference to:

using System.Data.Entity.Infrastructure.Annotations;

Basic Example

Here is a simple usage, adding an index on the User.FirstName property

modelBuilder 
    .Entity<User>() 
    .Property(t => t.FirstName) 
    .HasColumnAnnotation(IndexAnnotation.AnnotationName, new IndexAnnotation(new IndexAttribute()));

Practical Example:

Here is a more realistic example. It adds a unique index on multiple properties: User.FirstName and User.LastName, with an index name "IX_FirstNameLastName"

modelBuilder 
    .Entity<User>() 
    .Property(t => t.FirstName) 
    .IsRequired()
    .HasMaxLength(60)
    .HasColumnAnnotation(
        IndexAnnotation.AnnotationName, 
        new IndexAnnotation(
            new IndexAttribute("IX_FirstNameLastName", 1) { IsUnique = true }));

modelBuilder 
    .Entity<User>() 
    .Property(t => t.LastName) 
    .IsRequired()
    .HasMaxLength(60)
    .HasColumnAnnotation(
        IndexAnnotation.AnnotationName, 
        new IndexAnnotation(
            new IndexAttribute("IX_FirstNameLastName", 2) { IsUnique = true }));

The second way is the preferred option.

private readonly int MyVal = 5;

public int MyProp { get { return MyVal;}  }

This will ensure that MyVal can only be assigned at initialization (it can also be set in a constructor).

As you had noted - this way you are not exposing an internal member, allowing you to change the internal implementation in the future.

Tried to add this as a comment to Rob Prouse's posting, but the lack of formatting made it unintelligible.

In Visual Studio 2010, the "Tools | Options | Projects and Solutions | VC++ Directories" dialog reports that "VC++ Directories editing in Tools > Options has been deprecated", proposing that you use the rather counter-intuitive Property Manager.

If you really, really want to update the default $(IncludePath), you have to hack the appropriate entry in one of the XML files:

\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\PlatformToolsets\v100\Microsoft.Cpp.Win32.v100.props

or

\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\x64\PlatformToolsets\v100\Microsoft.Cpp.X64.v100.props

(Probably not Microsoft-recommended.)

You might want to modify your jQuery code a bit to '#demolist li a' so it specifically selects the text that is in the link rather than the text that is in the li element. That would allow you to have a sub-menu without causing issues. Also since your are specifically selecting the a tag you can access it with $(this).text();.

$('#datebox li a').on('click', function(){
    //$('#datebox').val($(this).text());
    alert($(this).text());
});

You should try something like this

List xx= (List) list.get(0)
String id = (String) xx.get(0)

or if you have a House value object the result of the query is of the same type, then

House myhouse = (House) list.get(0);

var val = $('input:checkbox:checked, input:radio:checked, \
   select option:selected, textarea, input:text',
   $('#container')).val();

Comments:

1. I assume, that there is exactly one form element, that can be either a textarea, input field, select form, a set of radio buttons or a single checkbox (you will have to update my code if you need more checkboxes).

2. The element in question lives inside an element with ID container (to remove ambiguences with other elements on the page).

3. The code will then return the value of the first matching element it finds. Since I use :checked and so on, this should always be exactly the value of what you're looking for.

Neither of answers worked for me even though I had my resources put in resources folders and followed the above answers. What did make a trick was:

@Value("file:*/**/resources/**/schema/*.json")
private Resource[] resources;

Make sure your iframe is already loaded. Old but reliable way without jQuery:

<iframe src="samedomain.com/page.htm" id="iframe" onload="access()"></iframe>

<script>
function access() {
   var iframe = document.getElementById("iframe");
   var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
   console.log(innerDoc.body);
}
</script>

If you are not giving any modifier to your method then as default it will be Default modifier which has scope within package.
for more info you can refer http://wiki.answers.com/Q/What_is_default_access_specifier_in_Java

Or you can just include the SELECT statement in the SQL that's invoking the trigger, so its passed in as one of the columns in the trigger row(s). As long as you're certain it will infallibly return only one row (hence one value). (And, of course, it must not return a value that interacts with the logic in the trigger, but that's true in any case.)

There are 4 main factors into why you would want to use synchronized or java.util.concurrent.Lock.

Note: Synchronized locking is what I mean when I say intrinsic locking.

1. When Java 5 came out with ReentrantLocks, they proved to have quite a noticeble throughput difference then intrinsic locking. If youre looking for faster locking mechanism and are running 1.5 consider j.u.c.ReentrantLock. Java 6's intrinsic locking is now comparable.

2. j.u.c.Lock has different mechanisms for locking. Lock interruptable - attempt to lock until the locking thread is interrupted; timed lock - attempt to lock for a certain amount of time and give up if you do not succeed; tryLock - attempt to lock, if some other thread is holding the lock give up. This all is included aside from the simple lock. Intrinsic locking only offers simple locking

3. Style. If both 1 and 2 do not fall into categories of what you are concerned with most people, including myself, would find the intrinsic locking semenatics easier to read and less verbose then j.u.c.Lock locking.
4. Multiple Conditions. An object you lock on can only be notified and waited for a single case. Lock's newCondition method allows for a single Lock to have mutliple reasons to await or signal. I have yet to actually need this functionality in practice, but is a nice feature for those who need it.

You can prevent printing a stack trace for KeyboardInterrupt, without try: ... except KeyboardInterrupt: pass (the most obvious and propably "best" solution, but you already know it and asked for something else) by replacing sys.excepthook. Something like

def custom_excepthook(type, value, traceback):
    if type is KeyboardInterrupt:
        return # do nothing
    else:
        sys.__excepthook__(type, value, traceback)

Maven lets you specify either goals or lifecycle phases on the command line (or both).

clean and install are two different phases of two different lifecycles, to which different plugin goals are bound (either per default or explicitly in your pom.xml)

The clean phase, per convention, is meant to make a build reproducible, i.e. it cleans up anything that was created by previous builds. In most cases it does that by calling clean:clean, which deletes the directory bound to ${project.build.directory} (usually called "target")

Using the latest versions of Subclipse, you can actually view them without using the cmd prompt. On the file, simply right-click => Team => Switch to another branch/tag/revision. Besides the revision field, you click select, and you'll see all the versions of that file.

ghostdog74's example provided the core of what I needed, since I've never written any vbs before and needed to do that. It's not perfect, but I fleshed out the example into a full script in case anyone finds it useful.

https://github.com/abdmob/x2js - my own library (updated URL from http://code.google.com/p/x2js/):

This library provides XML to JSON (JavaScript Objects) and vice versa javascript conversion functions. The library is very small and doesn't require any other additional libraries.

API functions

• new X2JS() - to create your instance to access all library functionality. Also you could specify optional configuration options here
• X2JS.xml2json - Convert XML specified as DOM Object to JSON
• X2JS.json2xml - Convert JSON to XML DOM Object
• X2JS.xml_str2json - Convert XML specified as string to JSON
• X2JS.json2xml_str - Convert JSON to XML string

Online Demo on http://jsfiddle.net/abdmob/gkxucxrj/1/

var x2js = new X2JS();
function convertXml2JSon() {
    $("#jsonArea").val(JSON.stringify(x2js.xml_str2json($("#xmlArea").val())));
}

function convertJSon2XML() {
    $("#xmlArea").val(x2js.json2xml_str($.parseJSON($("#jsonArea").val())));
}

convertXml2JSon();
convertJSon2XML();
$("#convertToJsonBtn").click(convertXml2JSon);
$("#convertToXmlBtn").click(convertJSon2XML);

I tried EVERY answer in this thread to no avail. Finally resolved my issue by matching the "Pre-Configuration Build Products Path" in my target project with the value in the Pods project. Turns out they were building to two different output locations. None of the other suggestions in this thread were relevant for me. Would be great if XCode gave a useful error description (like WHY it can't use the lib - File Not Found, No matching architecture found, etc.).

In handlebar version 4.0 onwards,

{{#list array}}
  {{@index}} 
{{/list}}

1 : if you are interested only in the static block of the class , the loading the class only would do , and would execute static blocks then all you need is:

Class.forName("Somthing");

2 : if you are interested in loading the class , execute its static blocks and also want to access its its non static part , then you need an instance and then you need:

Class.forName("Somthing").newInstance();

If you remove directives attribute it should work.

@Component({
    selector: 'parent',
    template: `
            <h1>Parent Component</h1>
            <child></child>
        `
    })
    export class ParentComponent{}


@Component({
    selector: 'child',    
    template: `
            <h4>Child Component</h4>
        `
    })
    export class ChildComponent{}

Directives are like components but they are used in attributes. They also have a declarator @Directive. You can read more about directives Structural Directives and Attribute Directives.

There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.

A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.

Also if you are open the glossary you can find that components are also directives.

Directives fall into one of the following categories:

• Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.

• Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.

• Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.

The difference that components have a template. See Angular Architecture overview.

A directive is a class with a @Directive decorator. A component is a directive-with-a-template; a @Component decorator is actually a @Directive decorator extended with template-oriented features.

The @Component metadata doesn't have directives attribute. See Component decorator.

If you need to store null characters in text fields and don't want to change your data type other than text then you can follow my solution too:

Before insert:

myValue = myValue.replaceAll("\u0000", "SomeVerySpecialText")

After select:

myValue = myValue.replaceAll("SomeVerySpecialText","\u0000")

I've used "null" as my SomeVerySpecialText which I am sure that there will be no any "null" string in my values at all.

Yes, the Map constructor takes an array of key-value pairs.

Object.entries is a new Object static method available in ES2017 (19.1.2.5).

const map = new Map(Object.entries({foo: 'bar'}));

map.get('foo'); // 'bar'

It's currently implemented in Firefox 46+ and Edge 14+ and newer versions of Chrome

If you need to support older environments and transpilation is not an option for you, use a polyfill, such as the one recommended by georg:

Object.entries = typeof Object.entries === 'function' ? Object.entries : obj => Object.keys(obj).map(k => [k, obj[k]]);

For me, it was Maps Embed API that I had to enable.

In the Google Cloud Console

Go to API tab, look through the Additional APIs section and try to enable any map-related APIs.

This worked for me...

If you're going to be doing this search frequently, consider changing the format of your object so dinner actually is a key. This is kind of like assigning a primary clustered key in a database table. So, for example:

Obj = { 'pizza' : { 'name' : 'bob' }, 'sushi' : { 'name' : 'john' } }

You can now easily access it like this: Object['sushi']['name']

Or if the object really is this simple (just 'name' in the object), you could just change it to:

Obj = { 'pizza' : 'bob', 'sushi' : 'john' }

And then access it like: Object['sushi'].

It's obviously not always possible or to your advantage to restructure your data object like this, but the point is, sometimes the best answer is to consider whether your data object is structured the best way. Creating a key like this can be faster and create cleaner code.

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

By default, Sublime Text set 'UTF8 without BOM', but that wasn't specified.

The only specicified things is 'UTF8 with BOM'.

Hope this help :)

Apply following style to carousel listbox.

<div class="carousel-inner" role="listbox" style=" width:100%; height: 500px !important;">_x000D_
_x000D_
..._x000D_
_x000D_
</div

my way is this

subjcts is

[{"id":"1","title":"GFATM"},{"id":"2","title":"Court Case"},{"id":"3","title":"Renewal\/Validity"},{"id":"4","title":"Change of Details"},{"id":"5","title":"Student Query"},{"id":"6","title":"Complains"}]

sub is a Input field or whatever you like

Displaying like this

<div ng-if="x.id === sub" ng-repeat=" x in subjcts">{{x.title}}</div>

I found InfoBox perfect for advanced styling.

An InfoBox behaves like a google.maps.InfoWindow, but it supports several additional properties for advanced styling. An InfoBox can also be used as a map label. An InfoBox also fires the same events as a google.maps.InfoWindow.

Include http://code.google.com/p/google-maps-utility-library-v3/source/browse/trunk/infobox/src/infobox.js in your page

One of the reasons of your problem could be the password policy you are using.

And if there is no such policy of yours then check your settings for the password properties in the DEFAULT profile with the following query:

SELECT resource_name, limit
FROM dba_profiles 
WHERE profile = 'DEFAULT'
AND resource_type = 'PASSWORD';

And If required, you just need to change the PASSWORD_LIFE_TIME to unlimited with the following query:

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

Another way to detect device orientations is with the function traitCollectionDidChange(_:). The system calls this method when the iOS interface environment changes.

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?)
{
    super.traitCollectionDidChange(previousTraitCollection)
    //...
}

Furthermore, you can use function willTransition(to:with:) ( which is called before traitCollectionDidChange(_:) ), to get information just before the orientation is applied.

 override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator)
{
    super.willTransition(to: newCollection, with: coordinator)
    //...
}

For Apache Spark 2+, in order to save dataframe into single csv file. Use following command

query.repartition(1).write.csv("cc_out.csv", sep='|')

Here 1 indicate that I need one partition of csv only. you can change it according to your requirements.

To state the obvious, the cup represents outerScopeVar.

Asynchronous functions be like...

To change the connect mode selection try Settings -> Wireless & Networks -> USB Connection. You can shoose to Charging, Mass Storage, Tethered, and ask on connection.

This is what is suggested by JeffreyWay in this Laracasts Discussion.

1. Within your app/Http directory, create a helpers.php file and add your functions.
2. Within composer.json, in the autoload block, add "files": ["app/Http/helpers.php"].
3. Run composer dump-autoload.

As mentioned in "Polling must die: triggering Jenkins builds from a git hook", you can notify Jenkins of a new commit:

With the latest Git plugin 1.1.14 (that I just release now), you can now do this more >easily by simply executing the following command:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>

This will scan all the jobs that’s configured to check out the specified URL, and if they are also configured with polling, it’ll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.)

This allows a script to remain the same when jobs come and go in Jenkins.
Or if you have multiple repositories under a single repository host application (such as Gitosis), you can share a single post-receive hook script with all the repositories. Finally, this URL doesn’t require authentication even for secured Jenkins, because the server doesn’t directly use anything that the client is sending. It runs polling to verify that there is a change, before it actually starts a build.

As mentioned here, make sure to use the right address for your Jenkins server:

since we're running Jenkins as standalone Webserver on port 8080 the URL should have been without the /jenkins, like this:

http://jenkins:8080/git/notifyCommit?url=git@gitserver:tools/common.git

To reinforce that last point, ptha adds in the comments:

It may be obvious, but I had issues with:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>. 

The url parameter should match exactly what you have in Repository URL of your Jenkins job.
When copying examples I left out the protocol, in our case ssh://, and it didn't work.

You can also use a simple post-receive hook like in "Push based builds using Jenkins and GIT"

#!/bin/bash
/usr/bin/curl --user USERNAME:PASS -s \

http://jenkinsci/job/PROJECTNAME/build?token=1qaz2wsx

Configure your Jenkins job to be able to “Trigger builds remotely” and use an authentication token (1qaz2wsx in this example).

However, this is a project-specific script, and the author mentions a way to generalize it.
The first solution is easier as it doesn't depend on authentication or a specific project.

I want to check in change set whether at least one java file is there the build should start.
Suppose the developers changed only XML files or property files, then the build should not start.

Basically, your build script can:

• put a 'build' notes (see git notes) on the first call
• on the subsequent calls, grab the list of commits between HEAD of your branch candidate for build and the commit referenced by the git notes 'build' (git show refs/notes/build): git diff --name-only SHA_build HEAD.
• your script can parse that list and decide if it needs to go on with the build.
• in any case, create/move your git notes 'build' to HEAD.

May 2016: cwhsu points out in the comments the following possible url:

you could just use curl --user USER:PWD http://JENKINS_SERVER/job/JOB_NAME/build?token=YOUR_TOKEN if you set trigger config in your item

June 2016, polaretto points out in the comments:

I wanted to add that with just a little of shell scripting you can avoid manual url configuration, especially if you have many repositories under a common directory.
For example I used these parameter expansions to get the repo name

repository=${PWD%/hooks}; 
repository=${repository##*/} 

and then use it like:

curl $JENKINS_URL/git/notifyCommit?url=$GIT_URL/$repository

Here is another version of regex to match any of the following date formats and allow leading zeros to be omitted:

Regex: ^[0-3]?[0-9].[0-3]?[0-9].(?:[0-9]{2})?[0-9]{2}$

Matches:

1/1/11 or 1.1.11 or 1-1-11 : true 01/01/11 or 01.01.11 or 01-01-11 : true 01/01/2011 or 01.01.2011 or 01-01-2011 : true 01/1/2011 or 01.1.2011 or 01-1-2011 : true 1/11/2011 or 1.11.2011 or 1-11-2011 : true 1/11/11 or 1.11.11 or 1-11-11 : true 11/1/11 or 11.1.11 or 11-1-11 : true

Debuggex Demo

This is totally valid, I do it all the time. I usually use IllegalArguemntException if it is a result of parameter checking.

In this case I wouldn't suggest asserts because they are turned off in a deployment build and you always want to stop this from happening, but they are valid if your group does ALL it's testing with asserts turned on and you think the chance of missing a parameter problem at runtime is more acceptable than throwing an exception that is maybe more likely to cause a runtime crash.

Also, an assert would be more difficult for the caller to trap, this is easy.

You probably want to list it as a "throws" in your method's javadocs along with the reason so that callers aren't surprised.

  is the numeric reference for the entity reference   — they are the exact same thing. It's likely your editor is simply inserting the numberic reference instead of the named one.

See the Wikipedia page for the non-breaking space.

Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:

sep=,

Now open it with excel again.

This will set the separator as a comma, or you can change it to whatever you need.

i supposed you uploaded your photo in your drive all what you need to do is while you are opening your google drive just open your dev tools in chrome and head to your img tag and copy the link beside the src attribute and use it

Create the reference of image....

UIImage *rainyImage = [UIImage imageNamed:@"rainy.jpg"];

displaying image in image view... imagedisplay is reference of imageview:

imagedisplay.image = rainyImage;

convert it into NSData by passing UIImage reference and provide compression quality in float values:

NSData *imgData = UIImageJPEGRepresentation(rainyImage, 0.9);

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

You could also do it like this, not sure if it's a good plan :D

class Parent extends Component {
  handleClick() {
    if (this._getAlert !== null) {
      this._getAlert()
    }
  }

  render() {
    return (
      <div>
        <Child>
        {(getAlert, childScope) => (
          <span> {!this._getAlert ? this._getAlert = getAlert.bind(childScope) : null}</span>
        )}
        </Child>
        <button onClick={() => this.handleClick()}> Click me</button>
      </div>
      );
    }
  }

class Child extends Component {
  constructor() {
    super();
    this.state = { count: 0 }
  }

  getAlert() {
    alert(`Child function called state: ${this.state.count}`);
    this.setState({ count: this.state.count + 1 });
  }

  render() {
    return this.props.children(this.getAlert, this)
  }
}

I used the above rule to fwd www to no www and it works fine for the homepage, however on the internal pages they are forwarding to /index.php

I found this other rule in my .htaccess file which is causing this but not sure what to do about it. Any suggestions would be great:

############################################
## always send 404 on missing files in these folders

    RewriteCond %{REQUEST_URI} !^/(media|skin|js)/

############################################
## never rewrite for existing files, directories and links

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l

############################################
## rewrite everything else to index.php

    RewriteRule .* index.php [L]

SELECT DECODE(REGEXP_COUNT(:value,'\d'),LENGTH(:value),'Y','N') AS is_numeric FROM dual;

There are many ways but this one works perfect for me.

Use this:

    public void ShowAllPostBackData()
    {
        if (IsPostBack)
        {
            string[] keys = Request.Form.AllKeys;
            Literal ctlAllPostbackData = new Literal();
            ctlAllPostbackData.Text = "<div class='well well-lg' style='border:1px solid black;z-index:99999;position:absolute;'><h3>All postback data:</h3><br />";
            for (int i = 0; i < keys.Length; i++)
            {
                ctlAllPostbackData.Text += "<b>" + keys[i] + "</b>: " + Request[keys[i]] + "<br />";
            }
            ctlAllPostbackData.Text += "</div>";
            this.Controls.Add(ctlAllPostbackData);
        }
    }

Andrew had a great response but I wanted to tweek it a little. The way this is different is that I like my ModelViews to not have overhead data in them. Just the data for the object. It seem that ViewData fits the bill for over head data, but of course I'm new at this. I suggest doing something like this.

Controller

virtual public ActionResult DisplaySomeWidget(int id)
{
    SomeModelView returnData = someDataMapper.getbyid(1);
    var serializer = new JavaScriptSerializer();
    ViewData["JSON"] = serializer.Serialize(returnData);
    return View(myview, returnData);
}

View

//create base js object;
var myWidget= new Widget(); //Widget is a class with a public member variable called data.
myWidget.data= <%= ViewData["JSON"] %>;

What This does for you is it gives you the same data in your JSON as in your ModelView so you can potentially return the JSON back to your controller and it would have all the parts. This is similar to just requesting it via a JSONRequest however it requires one less call so it saves you that overhead. BTW this is funky for Dates but that seems like another thread.

You can use in this way using bootstrap css. Just remove the active class if already assinged to any row and reassign to the current row.

    $(".table tr").each(function () {
        $(this).attr("class", "");
    });
    $(this).attr("class", "active");

As of 2018 and beyond, you have a more modern option which is to incorporate async/await in your ReactJS application. A promise-based HTTP client library such as axios can be used. The sample code is given below:

import axios from 'axios';
...
class Login extends Component {
    constructor(props, context) {
        super(props, context);
        this.onLogin = this.onLogin.bind(this);
        ...
    }
    async onLogin() {
        const { email, password } = this.state;
        try {
           const response = await axios.post('/login', { email, password });
           console.log(response);
        } catch (err) {
           ...
        }
    }
    ...
}

#include <unistd.h>
#include <termios.h>

char getch(void)
{
    char buf = 0;
    struct termios old = {0};
    fflush(stdout);
    if(tcgetattr(0, &old) < 0)
        perror("tcsetattr()");
    old.c_lflag &= ~ICANON;
    old.c_lflag &= ~ECHO;
    old.c_cc[VMIN] = 1;
    old.c_cc[VTIME] = 0;
    if(tcsetattr(0, TCSANOW, &old) < 0)
        perror("tcsetattr ICANON");
    if(read(0, &buf, 1) < 0)
        perror("read()");
    old.c_lflag |= ICANON;
    old.c_lflag |= ECHO;
    if(tcsetattr(0, TCSADRAIN, &old) < 0)
        perror("tcsetattr ~ICANON");
    printf("%c\n", buf);
    return buf;
 }

Remove the last printf if you don't want the character to be displayed.

Please note that MVC 3 onwards the persistence behavior of TempData has changed, now the value in TempData is persisted until it is read, and not just for the next request.

The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request. https://msdn.microsoft.com/en-in/library/dd394711%28v=vs.100%29.aspx

UPDATE

You can use document.location.reload(true) as mentioned below instead of the forced trick below.

Replace your HTML with this:

<!DOCTYPE html>
<html>
    <head>
        <style type="text/css">
            body { 
                background-image: url('../Images/Black-BackGround.gif');
                background-repeat: repeat;
            }
            body td {
               font-Family: Arial; 
               font-size: 12px; 
            }
            #Nav a { 
                position:relative; 
                display:block; 
                text-decoration: none; 
                color:black; 
            }
        </style>
        <script type="text/javascript">
            function refreshPage () {
                var page_y = document.getElementsByTagName("body")[0].scrollTop;
                window.location.href = window.location.href.split('?')[0] + '?page_y=' + page_y;
            }
            window.onload = function () {
                setTimeout(refreshPage, 35000);
                if ( window.location.href.indexOf('page_y') != -1 ) {
                    var match = window.location.href.split('?')[1].split("&")[0].split("=");
                    document.getElementsByTagName("body")[0].scrollTop = match[1];
                }
            }
        </script>
    </head>
    <body><!-- BODY CONTENT HERE --></body>

For System.Timers.Timer:

See Brian Gideon's answer below

For System.Threading.Timer:

MSDN Documentation on Timers states:

The System.Threading.Timer class makes callbacks on a ThreadPool thread and does not use the event model at all.

So indeed the timer elapses on a different thread.

If anyone is running into this issue with Typescript, the key to solving it for me was changing

    "target": "esnext",
    "module": "esnext",

to

    "target": "esnext",
    "module": "commonjs",

In my tsconfig.json. I was under the impression "esnext" was the "best", but that was just a mistake.

I am wondering why you cannot put this in a batch file. Example:

cd D:\VBS\
WSCript Converter.vbs

Put the above code in a text file and save the text file with .bat extension. Now you have to simply run this .bat file.

You could (but you shouldn't) use reflection for the job:

import java.lang.reflect.Field;

public class Outer {
    public class Inner {
    }

    public static void main(String[] args) throws Exception {

        // Create the inner instance
        Inner inner = new Outer().new Inner();

        // Get the implicit reference from the inner to the outer instance
        // ... make it accessible, as it has default visibility
        Field field = Inner.class.getDeclaredField("this$0");
        field.setAccessible(true);

        // Dereference and cast it
        Outer outer = (Outer) field.get(inner);
        System.out.println(outer);
    }
}

Of course, the name of the implicit reference is utterly unreliable, so as I said, you shouldn't :-)

In addition to all answers above:

If updating the cacerts file in JRE directory doesn't help, try to update it in JDK.

C:\Program Files\Java\jdk1.8.0_192\jre\lib\security

If you want to get the latest changes in a directory without entering it, you can do:

$ git -C <Path to directory> pull

File.Create returns a FileStream object that you can call Close() on.

@Query("SELECT distinct new com.model.referential.Asset(firefCode,firefDescription) FROM AssetClass ")
List<AssetClass> findDistinctAsset();

First of all, it is a waste of an executor slot to wrap the build step in node. Your upstream executor will just be sitting idle for no reason.

Second, from a multibranch project, you can use the environment variable BRANCH_NAME to make logic conditional on the current branch.

Third, the job parameter takes an absolute or relative job name. If you give a name without any path qualification, that would refer to another job in the same folder, which in the case of a multibranch project would mean another branch of the same repository.

Thus what you meant to write is probably

if (env.BRANCH_NAME == 'master') {
    build '../other-repo/master'
}

There are a couple of ways to accomplish this using the Arrays utility class.

If the array is not sorted and is not an array of primitives:

java.util.Arrays.asList(theArray).indexOf(o)

If the array is primitives and not sorted, one should use a solution offered by one of the other answers such as Kerem Baydogan's, Andrew McKinlay's or Mishax's. The above code will compile even if theArray is primitive (possibly emitting a warning) but you'll get totally incorrect results nonetheless.

If the array is sorted, you can make use of a binary search for performance:

java.util.Arrays.binarySearch(theArray, o)

1. literal_eval, a somewhat safer version of eval (will only evaluate literals ie strings, lists etc):

   from ast import literal_eval
   
   python_dict = literal_eval("{'a': 1}")
   

2. json.loads but it would require your string to use double quotes:

   import json
   
   python_dict = json.loads('{"a": 1}')
   

Simple one without rank :

rum[order(rum$I1, -rum$I2, decreasing = TRUE), ]

Try that;

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

Try something like this (on a test table first):

USE your_database_name
GO
WHILE (SELECT COUNT(*) FROM your_table WHERE your_id_field IS NULL) > 0
BEGIN
    SET ROWCOUNT 1
    UPDATE your_table SET your_id_field = MAX(your_id_field)+1
END
PRINT 'ALL DONE'

I have not tested this at all, so be careful!

The below code works for me -:

jQuery('[id^=select_] > option').each(function(){
        if (this.text.toLowerCase()=='text'){
            jQuery('[id^=select_]').val(this.value);
        }
});

jQuery('[id^=select_]') - This allows you to select drop down where ID of the drop down starts from select_

Hope the above helps!

I wrote a version that works using only numpy. I hope it helps you.

While formatting is likely that most Pythonic way, here is an alternate solution using the more_itertools.rstrip tool.

import more_itertools as mit


def fmt(num, pred=None):
    iterable = str(num)
    predicate = pred if pred is not None else lambda x: x in {".", "0"}
    return "".join(mit.rstrip(iterable, predicate))

assert fmt(3) == "3"
assert fmt(3.) == "3"
assert fmt(3.0) == "3"
assert fmt(3.1) == "3.1"
assert fmt(3.14) == "3.14"
assert fmt(3.140) == "3.14"
assert fmt(3.14000) == "3.14"
assert fmt("3,0", pred=lambda x: x in set(",0")) == "3"

The number is converted to a string, which is stripped of trailing characters that satisfy a predicate. The function definition fmt is not required, but it is used here to test assertions, which all pass. Note: it works on string inputs and accepts optional predicates.

See also details on this third-party library, more_itertools.

----------------WARM server.

step 1: go to cmd go to directory C:\wamp\bin\mysql\mysql5.6.17 hold Shift + right click (choose "open command window here")

step 2: C:\wamp\bin\mysql\mysql5.6.17\bin>mysql -u root -p SellProduct < D:\file.sql

in this case
+ Root is username database  
+ SellProduct is name database.
+ D:\file.sql is file you want to import

Subject is the certificate's common name and is a critical property for the certificate in a lot of cases if it's a server certificate and clients are looking for a positive identification.

As an example on an SSL certificate for a web site the subject would be the domain name of the web site.

<style name="progressColor" parent="Widget.AppCompat.ProgressBar">
    <item name="colorControlActivated">@color/colorPrimary</item>
</style>

You don't have jdk1.7.0_17 in your PATH - check again. There is only JRE which may not contain 'javac' compiler.

Besides it is best to set JAVA_HOME variable, and then include it in PATH.

There's a simpler way to do this:

$(newHtml).appendTo('#myDiv').effects(...);

This turns things around by first creating newHtml with jQuery(html [, ownerDocument ]), and then using appendTo(target) (note the "To" bit) to add that it to the end of #mydiv.

Because you now start with $(newHtml) the end result of appendTo('#myDiv') is that new bit of html, and the .effects(...) call will be on that new bit of html too.

Do it the jQuery way (and fix the errors):

$('#stop').click(function() {
     $('#next').click(stopMoving);
     // ^-- missing #
});  // <-- missing );

If the element already has a click handler attached via the onclick attribute, you have to remove it:

$('#next').attr('onclick', '');

Update: As @Drackir pointed out, you might also have to call $('#next').unbind('click'); in order to remove other click handlers attached via jQuery.

But this is guessing here. As always: More information => better answers.

You can make a json object like:

globalVariable={example_attribute:"SomeValue"}; 

in fileA.js

And access it from fileB.js like: globalVariable.example_attribute

Can be done on the same line using date.replace:

from datetime import datetime

datetime.today().replace(day=1)

I use PHP-ExcelReader to read xls files, and works great.

You start a thread which runs the static method SumData. However, SumData calls SetTextboxText which isn't static. Thus you need an instance of your form to call SetTextboxText.

cat foo.txt | strings -n 8 > bar.txt

will do the job.

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

#include <unistd.h>

int usleep(useconds_t useconds); //pass in microseconds

Calling length property on undefined or a null object will cause IE and webkit browsers to fail!

Instead try this:

if($("#something") !== null){
  // do something
}

or

if($("#something") === null){
  // don't do something
}

I am only using console.log in my code. So I include a very short 2 liner

var console = console || {};
console.log = console.log || function(){};

This was alluded to in another comment, but you could try something like this.

Sub FilterAndDelete()

Application.DisplayAlerts = False 

     With Sheet1 'Change this to your sheet name

         .AutoFilterMode = False   
         .Range("A3:K3").AutoFilter
         .Range("A3:K3").AutoFilter Field:=5, Criteria1:="none"
         .UsedRange.Offset(1, 0).Resize(ActiveSheet.UsedRange.Rows.Count - 1).Rows.Delete 

     End With

Application.DisplayAlerts = True

End Sub

I haven't tested this and it is from memory, so it may require some tweaking but it should get the job done without looping through thousands of rows. You'll need to remove the 11-Jul so that UsedRange is correct or change the offset to 2 rows instead of 1 in the .Offset(1,0).

Generally, before I do .Delete I will run the macro with .Select instead of the Delete that way I can be sure the correct range will be deleted, that may be worth doing to check to ensure the appropriate range is being deleted.

python_test.py

import subprocess
a = subprocess.check_output("batch_1.bat")
print a

This gives output from batch file to be print on the python IDLE/running console. So in batch file you can echo the result in each step to debug the issue. This is also useful in automation when there is an error happening in the batch call, to understand and locate the error easily.(put "echo off" in batch file beginning to avoid printing everything)

batch_1.bat

echo off    
echo "Hello World" 
md newdir 
echo "made new directory"

it allows you to kill a task based on the image name like taskkill /im iexplore.exe or taskkill /im notepad.exe

You can restart your current activity like this:

Fragment :

activity?.recreate()

Activity :

recreate()

Options:

• Use data.Seek as suggested by ken2k

• Use the somewhat simpler Position property:

  data.Position = 0;
  

• Use the ToArray call in MemoryStream to make your life simpler to start with:

  byte[] buf = data.ToArray();
  

The third option would be my preferred approach.

Note that you should have a using statement to close the file stream automatically (and optionally for the MemoryStream), and I'd add a using directive for System.IO to make your code cleaner:

byte[] buf;
using (MemoryStream data = new MemoryStream())
{
    using (Stream file = TestStream())
    {
        file.CopyTo(data);
        buf = data.ToArray();
    }
}

// Use buf

You might also want to create an extension method on Stream to do this for you in one place, e.g.

public static byte[] CopyToArray(this Stream input)
{
    using (MemoryStream memoryStream = new MemoryStream())
    {
        input.CopyTo(memoryStream);
        return memoryStream.ToArray();
    }
}

Note that this doesn't close the input stream.

The message you're getting isn't an error; it's just letting you know that you're not using a Network Security Configuration. If you want to add one, take a look at this page on the Android Developers website: https://developer.android.com/training/articles/security-config.html.

If you're using Node, you can try running the serve command directly in the console. In my case I'm running an angular application, so I tried with:

heroku run npm start

This showed me the exact error during the application startup.

@Eddie Loeffen's answer seems to be the most popular answer to this question, but it has some bad long term effects. If you review the documentation page for System.Net.ServicePointManager.SecurityProtocol here the remarks section implies that the negotiation phase should just address this (and forcing the protocol is bad practice because in the future, TLS 1.2 will be compromised as well). However, we wouldn't be looking for this answer if it did.

Researching, it appears that the ALPN negotiation protocol is required to get to TLS1.2 in the negotiation phase. We took that as our starting point and tried newer versions of the .Net framework to see where support starts. We found that .Net 4.5.2 does not support negotiation to TLS 1.2, but .Net 4.6 does.

So, even though forcing TLS1.2 will get the job done now, I recommend that you upgrade to .Net 4.6 instead. Since this is a PCI DSS issue for June 2016, the window is short, but the new framework is a better answer.

UPDATE: Working from the comments, I built this:

ServicePointManager.SecurityProtocol = 0;    
foreach (SecurityProtocolType protocol in SecurityProtocolType.GetValues(typeof(SecurityProtocolType)))
    {
        switch (protocol)
        {
            case SecurityProtocolType.Ssl3:
            case SecurityProtocolType.Tls:
            case SecurityProtocolType.Tls11:
                break;
            default:
                ServicePointManager.SecurityProtocol |= protocol;
            break;
        }
    }

In order to validate the concept, I or'd together SSL3 and TLS1.2 and ran the code targeting a server that supports only TLS 1.0 and TLS 1.2 (1.1 is disabled). With the or'd protocols, it seems to connect fine. If I change to SSL3 and TLS 1.1, that failed to connect. My validation uses HttpWebRequest from System.Net and just calls GetResponse(). For instance, I tried this and failed:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls11;
        request.GetResponse();

while this worked:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
        request.GetResponse();

This has an advantage over forcing TLS 1.2 in that, if the .Net framework is upgraded so that there are more entries in the Enum, they will be supported by the code as is. It has a disadvantage over just using .Net 4.6 in that 4.6 uses ALPN and should support new protocols if no restriction is specified.

Edit 4/29/2019 - Microsoft published this article last October. It has a pretty good synopsis of their recommendation of how this should be done in the various versions of .net framework.

You could say

 $name ne ""

instead of

 length $name > 0

Through the UI in SQL Server 2005 manager, change the column remove the autonumber (identity) property of the column (select the table by right clicking on it and choose "Design").

Then run your query:

UPDATE table SET Id = Id + 1

Then go and add the autonumber property back to the column.

If you need a function or a property to be tied to a class rather than to instances of it, you can declare it inside a companion object:

class Car(val horsepowers: Int) {
    companion object Factory {
        val cars = mutableListOf<Car>()

        fun makeCar(horsepowers: Int): Car {
            val car = Car(horsepowers)
            cars.add(car)
            return car
        }
    }
}

The companion object is a singleton, and its members can be accessed directly via the name of the containing class

val car = Car.makeCar(150)
println(Car.Factory.cars.size)

I came up with this:

import re

regex = re.compile("[A-Za-z]") # find a alpha
str = "1st str"
s = regex.search(str).group() # find the first alpha
str = str.replace(s, s.upper(), 1) # replace only 1 instance
print str

Here comes a solution with XSLT:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="//element3">
    <xsl:value-of select="element4/text()" />.<xsl:value-of select="element5/text()" />
</xsl:template>
</xsl:stylesheet>

I have created an answer for this post that might help: https://stackoverflow.com/a/63816822/2399164

Summary:

I am a little late to the game but I believe I found a simple solution to this problem...

1. Create a "NuGet.Config" file in the same directory as your .sln

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="{{CUSTOM NAME}}" value="{{CUSTOM SOURCE}}" />
  </packageSources>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
</configuration>

2. That is it! Create your "Dockerfile" here as well

3. Run docker build with your Dockerfile and all will get resolved

Most of the time, the best solution is using distinct() from dplyr, as has already been suggested.

However, here's another approach that uses the slice() function from dplyr.

# Generate fake data for the example
  library(dplyr)
  set.seed(123)
  df <- data.frame(
    x = sample(0:1, 10, replace = T),
    y = sample(0:1, 10, replace = T),
    z = 1:10
  )

# In each group of rows formed by combinations of x and y
# retain only the first row

    df %>%
      group_by(x, y) %>%
      slice(1)

Difference from using the distinct() function

The advantage of this solution is that it makes it explicit which rows are retained from the original dataframe, and it can pair nicely with the arrange() function.

Let's say you had customer sales data and you wanted to retain one record per customer, and you want that record to be the one from their latest purchase. Then you could write:

customer_purchase_data %>%
   arrange(desc(Purchase_Date)) %>%
   group_by(Customer_ID) %>%
   slice(1)

On Bootsrap 4.0.0-beta.2, none of the answers listed here worked for me. Finally, the Bootstrap site gave me the solution, not via its doc but via its page source code...

Getbootstrap.com align their right navbar-nav to the right with the help of the following class: ml-md-auto.

Bootstrap 4 alpha, for margin-top: shorthand CSS class names mt-1, mt-2 ( mt-lg-5, mt-sm-2) same for the bottom, right, left, and you have also auto class ml-auto

    <div class="mt-lg-1" ...>

Units are from 1 to 5 : in the variables.scss which means if you set mt-1 it gives .25rem of margin top.

$spacers: (
  0: (
    x: 0,
    y: 0
  ),
  1: (
    x: ($spacer-x * .25),
    y: ($spacer-y * .25)
  ),
  2: (
    x: ($spacer-x * .5),
    y: ($spacer-y * .5)
  ),
  3: (
    x: $spacer-x,
    y: $spacer-y
  ),
  4: (
    x: ($spacer-x * 1.5),
    y: ($spacer-y * 1.5)
  ),
  5: (
    x: ($spacer-x * 3),
    y: ($spacer-y * 3)
  )
) !default;

You can create fully custom spinner design like as

Step1: In drawable folder make background.xml for a border of the spinner.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/transparent" />
<corners android:radius="5dp" />
<stroke
android:width="1dp"
   android:color="@android:color/darker_gray" />
</shape>

Step2: for layout design of spinner use this drop-down icon or any image drop.png

 <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginRight="3dp"
    android:layout_weight=".28"
    android:background="@drawable/spinner_border"
    android:orientation="horizontal">

    <Spinner
        android:id="@+id/spinner2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_gravity="center"
        android:background="@android:color/transparent"
        android:gravity="center"
        android:layout_marginLeft="5dp"
        android:spinnerMode="dropdown" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_gravity="center"
        android:src="@mipmap/drop" />

</RelativeLayout>

Finally looks like below image and it is everywhere clickable in round area and no need to write click Lister for imageView.

Step3: For drop-down design, remove the line from Dropdown ListView and change the background color, Create custom adapter like as

Spinner spinner = (Spinner) findViewById(R.id.spinner1);
String[] years = {"1996","1997","1998","1998"};
ArrayAdapter<CharSequence> langAdapter = new ArrayAdapter<CharSequence>(getActivity(), R.layout.spinner_text, years );
langAdapter.setDropDownViewResource(R.layout.simple_spinner_dropdown);
mSpinner5.setAdapter(langAdapter);

In layout folder create R.layout.spinner_text.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layoutDirection="ltr"
android:id="@android:id/text1"
style="@style/spinnerItemStyle"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:paddingLeft="2dp"
/>

In layout folder create simple_spinner_dropdown.xml

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="@style/spinnerDropDownItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="5dp"
android:singleLine="true" />

In styles, you can add custom dimensions and height as per your requirement.

<style name="spinnerItemStyle" parent="android:Widget.TextView.SpinnerItem">
</style>

<style name="spinnerDropDownItemStyle" parent="android:TextAppearance.Widget.TextView.SpinnerItem">
</style>

Finally looks like as

According to the requirement, you can change background color and text of drop-down color by changing the background color or text color of simple_spinner_dropdown.xml

A binary tree is a tree whose children are never more than two. A binary search tree follows the invariant that the left child should have a smaller value than the root node's key, while the right child should have a greater value than the root node's key.

I have a Joomla Module that displays stuff... and I want to be able to share that stuff on facebook and not the Page's Title Meta Description... so my workaround is to have a secret .php file on the server that gets executed when it detects the FB's

$_SERVER['HTTP_USER_AGENT']

if($_SERVER['HTTP_USER_AGENT'] != 'facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)') {
    echo 'Direct Access';
} else {
    echo 'FB Accessed';
}

and pass variables with the URL that formats that particular page with the title and meta desciption of the item I want to share from my joomla module...

a name="fb_share" share_url="MYURL/sharer.php?title=TITLE&desc=DESC"

hope this helps...

Non-python data is best bundled inside your Python modules using the package_data support in setuptools. One thing I strongly recommend is using namespace packages to create shared namespaces which multiple projects can use -- much like the Java convention of putting packages in com.yourcompany.yourproject (and being able to have a shared com.yourcompany.utils namespace).

Re branching and merging, if you use a good enough source control system it will handle merges even through renames; Bazaar is particularly good at this.

Contrary to some other answers here, I'm +1 on having a src directory top-level (with doc and test directories alongside). Specific conventions for documentation directory trees will vary depending on what you're using; Sphinx, for instance, has its own conventions which its quickstart tool supports.

Please, please leverage setuptools and pkg_resources; this makes it much easier for other projects to rely on specific versions of your code (and for multiple versions to be simultaneously installed with different non-code files, if you're using package_data).

You are looking for the request history.

The response.history attribute is a list of responses that led to the final URL, which can be found in response.url.

response = requests.get(someurl)
if response.history:
    print("Request was redirected")
    for resp in response.history:
        print(resp.status_code, resp.url)
    print("Final destination:")
    print(response.status_code, response.url)
else:
    print("Request was not redirected")

Demo:

>>> import requests
>>> response = requests.get('http://httpbin.org/redirect/3')
>>> response.history
(<Response [302]>, <Response [302]>, <Response [302]>)
>>> for resp in response.history:
...     print(resp.status_code, resp.url)
... 
302 http://httpbin.org/redirect/3
302 http://httpbin.org/redirect/2
302 http://httpbin.org/redirect/1
>>> print(response.status_code, response.url)
200 http://httpbin.org/get

You should be able to use

An id in a route should be viewed the same as an index to a list, and naming should proceed accordingly.

numbers = [1, 2, 3]

numbers            GET /numbers
numbers[1]         GET /numbers/1
numbers.push(4)    POST /numbers
numbers[1] = 23    UPDATE /numbers/1

But some resources don't use ids in their routes because there's either only one, or a user never has access to more than one, so those aren't lists:

GET /dashboard
DELETE /session
POST /login
GET /users/{:id}/profile
UPDATE /users/{:id}/profile

var x = $(this).attr("name");
$("#" + x).hide();

I have noticed that selecting the method name and pressing F2(Quick Documentation) dispalys it's JavaDoc. I am using Intellij 2016, and Eclipse Keymap

isfar<-load("C:/Users/isfar.RData") 
if(is.data.frame(isfar)){
   names(isfar)
}

If isfar is a dataframe, this will print out the names of its columns.

Run the following to get the right NVIDIA driver :

sudo ubuntu-drivers devices

Then pick the right and run:

I modified one of examples below description function array_search. Function searchItemsByKey return all value(s) by $key from multidimensional array ( N levels). Perhaps , it would be useful for somebody. Example:

 $arr = array(
     'XXX'=>array(
               'YYY'=> array(
                    'AAA'=> array(
                          'keyN' =>'value1'
                   )
               ),
              'ZZZ'=> array(
                    'BBB'=> array(
                          'keyN' => 'value2'
                   )
               )
              //.....
           )
);


$result = searchItemsByKey($arr,'keyN');

print '<pre>';
print_r($result);
print '<pre>';
// OUTPUT
Array
(
  [0] => value1
  [1] => value2
)

Function code:

function searchItemsByKey($array, $key)
{
   $results = array();

  if (is_array($array))
  {
    if (isset($array[$key]) && key($array)==$key)
        $results[] = $array[$key];

    foreach ($array as $sub_array)
        $results = array_merge($results, searchItemsByKey($sub_array, $key));
  }

 return  $results;
}

I think you've missed the point of access control.

A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.

Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.

In your specific case, it seems that paste.ee doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).

Note that re.match(pattern, string, flags=0) only returns matches at the beginning of the string. If you want to locate a match anywhere in the string, use re.search(pattern, string, flags=0) instead (https://docs.python.org/3/library/re.html). This will scan the string and return the first match object. Then you can extract the matching string with match_object.group(0) as the folks suggested.

I too was looking for this for Facebook reasons and none of the answers given so far worked as needed or are too complicated.

@Request.Url.GetLeftPart(UriPartial.Path)

Gets the full protocol, host and path "without" the querystring. Also includes the port if you are using something other than the default 80.

Start Activity2 with startActivityForResult and use setResult method for sending data back from Activity2 to Activity1. In Activity1 you will need to override onActivityResult for updating TextView with EditText data from Activity2.

For example:

In Activity1, start Activity2 as:

Intent i = new Intent(this, Activity2.class);
startActivityForResult(i, 1);

In Activity2, use setResult for sending data back:

Intent intent = new Intent();
intent.putExtra("editTextValue", "value_here")
setResult(RESULT_OK, intent);        
finish();

And in Activity1, receive data with onActivityResult:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1) {
         if(resultCode == RESULT_OK) {
             String strEditText = data.getStringExtra("editTextValue");
         }     
    }
} 

If you can, also use SharedPreferences for sharing data between Activities.

Element, Pseudo Element: d = 1 – (0,0,0,1)
Class, Pseudo class, Attribute: c = 1 – (0,0,1,0)
Id: b = 1 – (0,1,0,0)
Inline Style: a = 1 – (1,0,0,0)

Inline css ( html style attribute ) overrides css rules in style tag and css file

A more specific selector takes precedence over a less specific one.

Rules that appear later in the code override earlier rules if both have the same specificity.

Command:

foo >> output.txt 2>&1

appends to the output.txt file, without replacing the content.

You just need to put your war file in webapps and then start your server.

it will get deployed.

otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.

string result = myList.FirstOrDefault(x => x == myString)
if(result != null)
{
  //found
}

Just to give a short, working example to see an effect of their difference

new Thread(foo).Start();

private void foo()
{
  this.Dispatcher.BeginInvoke(DispatcherPriority.Normal,
    (ThreadStart)delegate()
    {
        myTextBox.Text = "bing";
        Thread.Sleep(TimeSpan.FromSeconds(3));
    });
  MessageBox.Show("done");
}

If use BeginInvoke, MessageBox pops simultaneous to the text update. If use Invoke, MessageBox pops after the 3 second sleep. Hence, showing the effect of an asynchronous (BeginInvoke) and a synchronous (Invoke) call.

With Java 8, there are more elegant and functional ways to solve this.

LCM:

private static int lcm(int numberOne, int numberTwo) {
    final int bigger = Math.max(numberOne, numberTwo);
    final int smaller = Math.min(numberOne, numberTwo);

    return IntStream.rangeClosed(1,smaller)
                    .filter(factor -> (factor * bigger) % smaller == 0)
                    .map(factor -> Math.abs(factor * bigger))
                    .findFirst()
                    .getAsInt();
}

GCD:

private static int gcd(int numberOne, int numberTwo) {
    return (numberTwo == 0) ? numberOne : gcd(numberTwo, numberOne % numberTwo);
}

Of course if one argument is 0, both methods will not work.

The different types of JOINs:

• INNER JOIN
• LEFT and RIGHT OUTER JOIN
• FULL JOIN
• CROSS JOIN

See Jeff Atwood's Visual Explanation of JOINs

• What is a key? A candidate key? A primary key? An alternate key? A foreign key?

• What is an index and how does it help your database?

• What are the data types available and when to use which ones?

This is a circular dependency issue. Golang programs must be acyclic. In Golang cyclic imports are not allowed (That is its import graph must not contain any loops)

Lets say your project go-circular-dependency have 2 packages "package one" & it has "one.go" & "package two" & it has "two.go" So your project structure is as follows

+--go-circular-dependency    
      +--one    
         +-one.go
      +--two        
         +-two.go

This issue occurs when you try to do something like following.

Step 1 - In one.go you import package two (Following is one.go)

package one

import (
    "go-circular-dependency/two"
)

//AddOne is
func AddOne() int {
    a := two.Multiplier()
    return a + 1
}

Step 2 - In two.go you import package one (Following is two.go)

package two

import (
    "fmt"
    "go-circular-dependency/one"
)

//Multiplier is going to be used in package one
func Multiplier() int {
    return 2
}

//Total is
func Total() {
    //import AddOne from "package one"
    x := one.AddOne()
    fmt.Println(x)
}

In Step 2, you will receive an error "can't load package: import cycle not allowed" (This is called "Circular Dependency" error)

Technically speaking this is bad design decision and you should avoid this as much as possible, but you can "Break Circular Dependencies via implicit interfaces" (I personally don't recommend, and highly discourage this practise, because by design Go programs must be acyclic)

Try to keep your import dependency shallow. When the dependency graph becomes deeper (i.e package x imports y, y imports z, z imports x) then circular dependencies become more likely.

Sometimes code repetition is not bad idea, which is exactly opposite of DRY (don't repeat yourself)

So in Step 2 that is in two.go you should not import package one. Instead in two.go you should actually replicate the functionality of AddOne() written in one.go as follows.

package two

import (
    "fmt"
)

//Multiplier is going to be used in package one
func Multiplier() int {
    return 2
}

//Total is
func Total() {
    // x := one.AddOne()
    x := Multiplier() + 1
    fmt.Println(x)
}

There must be already a AssemblyInfo.cs file in the project here:

To solve: - Delete any one AssemblyInfo.cs

SELECT distinct
  group, 
  max_date = MAX(date) OVER (PARTITION BY group), checks
FROM table

Should work.

You can accomplish this in a very back-handed way with the following code:

exports.getStaticCompanies = function () {
    var ids = [46128, 2865, 49569, 1488, 45600, 61991, 1418, 61919, 53326, 61680]
    return Company.findAll({
        where: {
            id: ids
        },
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at'],
        order: sequelize.literal('(' + ids.map(function(id) {
            return '"Company"."id" = \'' + id + '\'');
        }).join(', ') + ') DESC')
    });
};

This is somewhat limited because it's got very bad performance characteristics past a few dozen records, but it's acceptable at the scale you're using.

This will produce a SQL query that looks something like this:

[...] ORDER BY ("Company"."id"='46128', "Company"."id"='2865', "Company"."id"='49569', [...])

Use the Timer class.

public static void Main()
{
    System.Timers.Timer aTimer = new System.Timers.Timer();
    aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
    aTimer.Interval = 5000;
    aTimer.Enabled = true;

    Console.WriteLine("Press \'q\' to quit the sample.");
    while(Console.Read() != 'q');
}

 // Specify what you want to happen when the Elapsed event is raised.
 private static void OnTimedEvent(object source, ElapsedEventArgs e)
 {
     Console.WriteLine("Hello World!");
 }

The Elapsed event will be raised every X amount of milliseconds, specified by the Interval property on the Timer object. It will call the Event Handler method you specify. In the example above, it is OnTimedEvent.

If you wanted to find all the primes in a range you could do this:

def is_prime(num):
"""Returns True if the number is prime
else False."""
if num == 0 or num == 1:
    return False
for x in range(2, num):
    if num % x == 0:
        return False
else:
    return True
num = 0
itr = 0
tot = ''
while itr <= 100:
    itr = itr + 1
    num = num + 1
    if is_prime(num) == True:
        print(num)
        tot = tot + ' ' + str(num)
print(tot)

Just add while its <= and your number for the range.
OUTPUT:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101

One way of achieving this is to make your class implement OnClickListener and then add it to your buttons like this:

Example:

//make your class implement OnClickListener
public class MyClass implements OnClickListener{

        ...

        //Create your buttons and set their onClickListener to "this"
        Button b1 = (Button) findViewById(R.id.buttonplay);   
        b1.setOnClickListener(this);

        Button b2 = (Button) findViewById(R.id.buttonstop);   
        b2.setOnClickListener(this);

        ...

        //implement the onClick method here
        public void onClick(View v) {
           // Perform action on click
          switch(v.getId()) {
            case R.id.buttonplay:
              //Play voicefile
              MediaPlayer.create(getBaseContext(), R.raw.voicefile).start();
              break;
            case R.id.buttonstop:
              //Stop MediaPlayer
              MediaPlayer.create(getBaseContext(), R.raw.voicefile).stop();
              break;
          }
       }
}

Here's an easier way:

sudo apt-get install maven

More details are here.

This stuff comes from ES file explorer

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

In Java or C#, an object cannot change its type once it has been instantiated.

So, if your object need to appear as a different object or behave differently depending on an object state or conditions, then use Composition: Refer to State and Strategy Design Patterns.

If the object need to be of the same type, then use Inheritance or implement interfaces.

try port 25 instead of 456.

I got the same error when using port 456, and changing it to 25 worked for me.

You can use Path.GetFileName to get the filename from the full path

private string[] pdfFiles = Directory.GetFiles("C:\\Documents", "*.pdf")
                                     .Select(Path.GetFileName)
                                     .ToArray();

EDIT: the solution above uses LINQ, so it requires .NET 3.5 at least. Here's a solution that works on earlier versions:

private string[] pdfFiles = GetFileNames("C:\\Documents", "*.pdf");

private static string[] GetFileNames(string path, string filter)
{
    string[] files = Directory.GetFiles(path, filter);
    for(int i = 0; i < files.Length; i++)
        files[i] = Path.GetFileName(files[i]);
    return files;
}

This should work:

data.groupby(lambda x: data['date'][x].year)

arrays:

• are a builtin language construct;
• come almost unmodified from C89;
• provide just a contiguous, indexable sequence of elements; no bells and whistles;
• are of fixed size; you can't resize an array in C++ (unless it's an array of POD and it's allocated with malloc);
• their size must be a compile-time constant unless they are allocated dynamically;
• they take their storage space depending from the scope where you declare them;
• if dynamically allocated, you must explicitly deallocate them;
• if they are dynamically allocated, you just get a pointer, and you can't determine their size; otherwise, you can use sizeof (hence the common idiom sizeof(arr)/sizeof(*arr), that however fails silently when used inadvertently on a pointer);
• automatically decay to a pointers in most situations; in particular, this happens when passing them to a function, which usually requires passing a separate parameter for their size;
• can't be returned from a function;
• can't be copied/assigned directly;
• dynamical arrays of objects require a default constructor, since all their elements must be constructed first;

std::vector:

• is a template class;
• is a C++ only construct;
• is implemented as a dynamic array;
• grows and shrinks dynamically;
• automatically manage their memory, which is freed on destruction;
• can be passed to/returned from functions (by value);
• can be copied/assigned (this performs a deep copy of all the stored elements);
• doesn't decay to pointers, but you can explicitly get a pointer to their data (&vec[0] is guaranteed to work as expected);
• always brings along with the internal dynamic array its size (how many elements are currently stored) and capacity (how many elements can be stored in the currently allocated block);
• the internal dynamic array is not allocated inside the object itself (which just contains a few "bookkeeping" fields), but is allocated dynamically by the allocator specified in the relevant template parameter; the default one gets the memory from the freestore (the so-called heap), independently from how where the actual object is allocated;
• for this reason, they may be less efficient than "regular" arrays for small, short-lived, local arrays;
• when reallocating, the objects are copied (moved, in C++11);
• does not require a default constructor for the objects being stored;
• is better integrated with the rest of the so-called STL (it provides the begin()/end() methods, the usual STL typedefs, ...)

Also consider the "modern alternative" to arrays - std::array; I already described in another answer the difference between std::vector and std::array, you may want to have a look at it.

I needed to print a binary tree in one of my projects, for that I have prepared a java class TreePrinter, one of the sample output is:

                [+]
               /   \
              /     \
             /       \
            /         \
           /           \
        [*]             \
       /   \             [-]
[speed]     [2]         /   \
                    [45]     [12]

Here is the code for class TreePrinter along with class TextNode. For printing any tree you can just create an equivalent tree with TextNode class.

import java.util.ArrayList;

public class TreePrinter {

    public TreePrinter(){
    }

    public static String TreeString(TextNode root){
        ArrayList layers = new ArrayList();
        ArrayList bottom = new ArrayList();

        FillBottom(bottom, root);  DrawEdges(root);

        int height = GetHeight(root);
        for(int i = 0; i  s.length()) min = s.length();

            if(!n.isEdge) s += "[";
            s += n.text;
            if(!n.isEdge) s += "]";

            layers.set(n.depth, s);
        }

        StringBuilder sb = new StringBuilder();

        for(int i = 0; i  temp = new ArrayList();

            for(int i = 0; i  0) temp.get(i-1).left = x;
                temp.add(x);
            }

            temp.get(count-1).left = n.left;
            n.left.depth = temp.get(count-1).depth+1;
            n.left = temp.get(0);

            DrawEdges(temp.get(count-1).left);
        }
        if(n.right != null){
            int count = n.right.x - (n.x + n.text.length() + 2);
            ArrayList temp = new ArrayList();

            for(int i = 0; i  0) temp.get(i-1).right = x;
                temp.add(x);
            }

            temp.get(count-1).right = n.right;
            n.right.depth = temp.get(count-1).depth+1;
            n.right = temp.get(0);  

            DrawEdges(temp.get(count-1).right);
        }
    }

    private static void FillBottom(ArrayList bottom, TextNode n){
        if(n == null) return;

        FillBottom(bottom, n.left);

        if(!bottom.isEmpty()){            
            int i = bottom.size()-1;
            while(bottom.get(i).isEdge) i--;
            TextNode last = bottom.get(i);

            if(!n.isEdge) n.x = last.x + last.text.length() + 3;
        }
        bottom.add(n);
        FillBottom(bottom, n.right);
    }

    private static boolean isLeaf(TextNode n){
        return (n.left == null && n.right == null);
    }

    private static int GetHeight(TextNode n){
        if(n == null) return 0;

        int l = GetHeight(n.left);
        int r = GetHeight(n.right);

        return Math.max(l, r) + 1;
    }
}


class TextNode {
    public String text;
    public TextNode parent, left, right;
    public boolean isEdge;
    public int x, depth;

    public TextNode(String text){
        this.text = text;
        parent = null; left = null; right = null;
        isEdge = false;
        x = 0; depth = 0;
    }
}

Finally here is a test class for printing given sample:

public class Test {

    public static void main(String[] args){
        TextNode root = new TextNode("+");
        root.left = new TextNode("*");            root.left.parent = root;
        root.right = new TextNode("-");           root.right.parent = root;
        root.left.left = new TextNode("speed");   root.left.left.parent = root.left;
        root.left.right = new TextNode("2");      root.left.right.parent = root.left;
        root.right.left = new TextNode("45");     root.right.left.parent = root.right;
        root.right.right = new TextNode("12");    root.right.right.parent = root.right;

        System.out.println(TreePrinter.TreeString(root));
    }
}

Try using this this work for me

select *  from `table_name` ORDER BY STR_TO_DATE(start_date,"%d-%m-%Y") ASC

where start_date is the field name

I too had the same error in trace logs. My newly created function in API was throwing the same error but to my surprise, the old functions were performing good. The issue was - My contract data members had few variables of type object. soap-xml was not able to handle it well, however, I can see that array of object types (object[]) were getting passed without any issues. Only a simple object type was not getting parsed by soap. This could be one more reason why the services throw the above error.

I think you're looking for the stat function (perldoc -f stat)

In particular, the 9th field (10th, index #9) of the returned list is the last modify time of the file in seconds since the epoch.

So:

my $last_modified = (stat($fh))[9];

The usual way to submit a form in general is to call submit() on the form itself, as described in krtek's answer.

However, if you need to actually click a submit button for some reason (your code depends on the submit button's name/value being posted or something), you can click on the submit button itself like this:

document.getElementById('loginSubmit').click();

In the case where one is using the ADO.NET Entity Framework, EchoStorm's solution also works perfectly. But it took me a few minutes to wrap my head around it. Assuming you have a database context, dc, and want to find rows in table x not linked in table y, the complete answer answer looks like:

var linked =
  from x in dc.X
  from y in dc.Y
  where x.MyProperty == y.MyProperty
  select x;
var notLinked =
  dc.X.Except(linked);

In response to Andy's comment, yes, one can have two from's in a LINQ query. Here's a complete working example, using lists. Each class, Foo and Bar, has an Id. Foo has a "foreign key" reference to Bar via Foo.BarId. The program selects all Foo's not linked to a corresponding Bar.

class Program
{
    static void Main(string[] args)
    {
        // Creates some foos
        List<Foo> fooList = new List<Foo>();
        fooList.Add(new Foo { Id = 1, BarId = 11 });
        fooList.Add(new Foo { Id = 2, BarId = 12 });
        fooList.Add(new Foo { Id = 3, BarId = 13 });
        fooList.Add(new Foo { Id = 4, BarId = 14 });
        fooList.Add(new Foo { Id = 5, BarId = -1 });
        fooList.Add(new Foo { Id = 6, BarId = -1 });
        fooList.Add(new Foo { Id = 7, BarId = -1 });

        // Create some bars
        List<Bar> barList = new List<Bar>();
        barList.Add(new Bar { Id = 11 });
        barList.Add(new Bar { Id = 12 });
        barList.Add(new Bar { Id = 13 });
        barList.Add(new Bar { Id = 14 });
        barList.Add(new Bar { Id = 15 });
        barList.Add(new Bar { Id = 16 });
        barList.Add(new Bar { Id = 17 });

        var linked = from foo in fooList
                     from bar in barList
                     where foo.BarId == bar.Id
                     select foo;
        var notLinked = fooList.Except(linked);
        foreach (Foo item in notLinked)
        {
            Console.WriteLine(
                String.Format(
                "Foo.Id: {0} | Bar.Id: {1}",
                item.Id, item.BarId));
        }
        Console.WriteLine("Any key to continue...");
        Console.ReadKey();
    }
}

class Foo
{
    public int Id { get; set; }
    public int BarId { get; set; }
}

class Bar
{
    public int Id { get; set; }
}

One way to resolve this is to login to your root user in phpmyadmin, go to the users tab, find and select the specific user that can't access the select and other queries . Then tick the all checkboxes and just click go. Now that user can select, update and whatever they want.

Update: I wrote a solution that doesn't require reading the entire file in one go. It's too big for a stackoverflow answer, but can be found here jsonstream.

You can use json.JSONDecoder.raw_decode to decode arbitarily big strings of "stacked" JSON (so long as they can fit in memory). raw_decode stops once it has a valid object and returns the last position where wasn't part of the parsed object. It's not documented, but you can pass this position back to raw_decode and it start parsing again from that position. Unfortunately, the Python json module doesn't accept strings that have prefixing whitespace. So we need to search to find the first none-whitespace part of your document.

from json import JSONDecoder, JSONDecodeError
import re

NOT_WHITESPACE = re.compile(r'[^\s]')

def decode_stacked(document, pos=0, decoder=JSONDecoder()):
    while True:
        match = NOT_WHITESPACE.search(document, pos)
        if not match:
            return
        pos = match.start()
        
        try:
            obj, pos = decoder.raw_decode(document, pos)
        except JSONDecodeError:
            # do something sensible if there's some error
            raise
        yield obj

s = """

{"a": 1}  


   [
1
,   
2
]


"""

for obj in decode_stacked(s):
    print(obj)

prints:

{'a': 1}
[1, 2]

It can be done like this

(function(X, Y) {_x000D_
  _x000D_
  // X is the local name of the 'class'_x000D_
  // Doo is default value if param X is empty_x000D_
  var X = (typeof X == 'string') ? X: 'Doo';_x000D_
  var Y = (typeof Y == 'string') ? Y: 'doo';_x000D_
  _x000D_
  // this refers to the local X defined above_x000D_
  this[X] = function(doo) {_x000D_
    // object variable_x000D_
    this.doo = doo || 'doo it';_x000D_
  }_x000D_
  // prototypal inheritance for methods_x000D_
  // defined by another_x000D_
  this[X].prototype[Y] = function() {_x000D_
    return this.doo || 'doo';_x000D_
  };_x000D_
  _x000D_
  // make X global_x000D_
  window[X] = this[X];_x000D_
}('Dooa', 'dooa')); // give the names here_x000D_
_x000D_
// test_x000D_
doo = new Dooa('abc');_x000D_
doo2 = new Dooa('def');_x000D_
console.log(doo.dooa());_x000D_
console.log(doo2.dooa());

The order is always implied in the structure of the regular expression. To accomplish what you want, you'll have to match the input string multiple times against different expressions.

What you want to do is not possible with a single regexp.

public void javascriptclick(String element)
    { 
        WebElement webElement=driver.findElement(By.xpath(element));
        JavascriptExecutor js = (JavascriptExecutor) driver;

        js.executeScript("arguments[0].click();",webElement);   
        System.out.println("javascriptclick"+" "+ element);

    }

How about this?

var http = require('http'), 
fs = require('fs'), 
options;

options = {
    host: 'www.google.com' , 
    port: 80,
    path: '/images/logos/ps_logo2.png'
}

var request = http.get(options, function(res){

//var imagedata = ''
//res.setEncoding('binary')

var chunks = [];

res.on('data', function(chunk){

    //imagedata += chunk
    chunks.push(chunk)

})

res.on('end', function(){

    //fs.writeFile('logo.png', imagedata, 'binary', function(err){

    var buffer = Buffer.concat(chunks)
    fs.writeFile('logo.png', buffer, function(err){
        if (err) throw err
        console.log('File saved.')
    })

})

You can use pg_terminate_backend() to kill a connection. You have to be superuser to use this function. This works on all operating systems the same.

SELECT 
    pg_terminate_backend(pid) 
FROM 
    pg_stat_activity 
WHERE 
    -- don't kill my own connection!
    pid <> pg_backend_pid()
    -- don't kill the connections to other databases
    AND datname = 'database_name'
    ;

Before executing this query, you have to REVOKE the CONNECT privileges to avoid new connections:

REVOKE CONNECT ON DATABASE dbname FROM PUBLIC, username;

If you're using Postgres 8.4-9.1 use procpid instead of pid

SELECT 
    pg_terminate_backend(procpid) 
FROM 
    pg_stat_activity 
WHERE 
    -- don't kill my own connection!
    procpid <> pg_backend_pid()
    -- don't kill the connections to other databases
    AND datname = 'database_name'
    ;

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

Both syntaxes are correct. But the result would be Array. You probably want to do something like this:

foreach ($tmpArray[1] as $value) {
  echo $value[0];
  foreach($value[1] as $val){
    echo $val;
  }
}

This will print out the string "two" ($value[0]) and the integers 4, 5 and 6 from the array ($value[1]).

Edit 2019 (8 years later), Scala-IO being not very active, if any, Li Haoyi suggests his own library lihaoyi/os-lib, that he presents below.

June 2019, Xavier Guihot mentions in his answer the library Using, a utility for performing automatic resource management.

Edit (September 2011): since Eduardo Costa asks about Scala2.9, and since Rick-777 comments that scalax.IO commit history is pretty much non-existent since mid-2009...

Scala-IO has changed place: see its GitHub repo, from Jesse Eichar (also on SO):

The Scala IO umbrella project consists of a few sub projects for different aspects and extensions of IO.
There are two main components of Scala IO:

• Core - Core primarily deals with Reading and writing data to and from arbitrary sources and sinks. The corner stone traits are Input, Output and Seekable which provide the core API.
  Other classes of importance are Resource, ReadChars and WriteChars.
• File - File is a File (called Path) API that is based on a combination of Java 7 NIO filesystem and SBT PathFinder APIs.
  Path and FileSystem are the main entry points into the Scala IO File API.

import scalax.io._

val output:Output = Resource.fromFile("someFile")

// Note: each write will open a new connection to file and 
//       each write is executed at the begining of the file,
//       so in this case the last write will be the contents of the file.
// See Seekable for append and patching files
// Also See openOutput for performing several writes with a single connection

output.writeIntsAsBytes(1,2,3)
output.write("hello")(Codec.UTF8)
output.writeStrings(List("hello","world")," ")(Codec.UTF8)

Original answer (January 2011), with the old place for scala-io:

If you don't want to wait for Scala2.9, you can use the scala-incubator / scala-io library.
(as mentioned in "Why doesn't Scala Source close the underlying InputStream?")

See the samples

{ // several examples of writing data
    import scalax.io.{
      FileOps, Path, Codec, OpenOption}
    // the codec must be defined either as a parameter of ops methods or as an implicit
    implicit val codec = scalax.io.Codec.UTF8


    val file: FileOps = Path ("file")

    // write bytes
    // By default the file write will replace
    // an existing file with the new data
    file.write (Array (1,2,3) map ( _.toByte))

    // another option for write is openOptions which allows the caller
    // to specify in detail how the write should take place
    // the openOptions parameter takes a collections of OpenOptions objects
    // which are filesystem specific in general but the standard options
    // are defined in the OpenOption object
    // in addition to the definition common collections are also defined
    // WriteAppend for example is a List(Create, Append, Write)
    file.write (List (1,2,3) map (_.toByte))

    // write a string to the file
    file.write("Hello my dear file")

    // with all options (these are the default options explicitely declared)
    file.write("Hello my dear file")(codec = Codec.UTF8)

    // Convert several strings to the file
    // same options apply as for write
    file.writeStrings( "It costs" :: "one" :: "dollar" :: Nil)

    // Now all options
    file.writeStrings("It costs" :: "one" :: "dollar" :: Nil,
                    separator="||\n||")(codec = Codec.UTF8)
  }

I was having an issue with ellipsis under chrome. Turning on white-space: nowrap seemed to fix it.

max-width: 95px;
max-height: 20px;
overflow: hidden;
display: inline-block;
text-overflow: ellipsis;
border: solid 1px black;
font-size: 12pt;
text-align: right;
white-space: nowrap;

Another way, simpler.

Add your

build.gradle

file to the root of your project. Close the project. Manually remove *.iml file. Then choose "Import Project...", navigate to your project directory, select the build.gradle file and click OK.

It sounds like you need to make use of advanced where clauses.

Given that search in field1 and field2 is constant we will leave them as is, but we are going to adjust your search in datefield a little.

Try this:

$query = Model::where('field1', 1)
    ->whereNull('field2')
    ->where(function ($query) {
        $query->where('datefield', '<', $date)
            ->orWhereNull('datefield');
    }
);

If you ever need to debug a query and see why it isn't working, it can help to see what SQL it is actually executing. You can chain ->toSql() to the end of your eloquent query to generate the SQL.

For (much) more power and flexibility, use a dedicated spellchecking library like PyEnchant. There's a tutorial, or you could just dive straight in:

>>> import enchant
>>> d = enchant.Dict("en_US")
>>> d.check("Hello")
True
>>> d.check("Helo")
False
>>> d.suggest("Helo")
['He lo', 'He-lo', 'Hello', 'Helot', 'Help', 'Halo', 'Hell', 'Held', 'Helm', 'Hero', "He'll"]
>>>

PyEnchant comes with a few dictionaries (en_GB, en_US, de_DE, fr_FR), but can use any of the OpenOffice ones if you want more languages.

There appears to be a pluralisation library called inflect, but I've no idea whether it's any good.

On thing to remember here is that the default param must be the last param in the function definition.

Following code will not compile:

void fun(int first, int second = 10, int third);

Following code will compile:

void fun(int first, int second, int third = 10);

1. Insert a column left to the column in question(adding column A beside column B).
2. Provide the value you want to append in 1st cell of column A
3. Insert a column right to the column in question ( column C)
4. Add this formula -> =CONCATENATE("A1","B1")
5. Drag it down to apply to all values in column
6. You will find concatenated values in column C

This worked for me !

If you want it really easy and a joy to automate, check out Chocolatey.org/install and you can basically copy and paste these commands and tweak it based on what versions of VC++ you need.

This command is taken from https://chocolatey.org/install

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Once you have chocolatey installed you can either close and reopen your Powershell terminal or run this command:

Import-Module "$env:ChocolateyInstall\helpers\chocolateyInstaller.psm1" ; Update-SessionEnvironment

Now you can use Chocolatey to install Python (latest version of 3.x is default).

choco install python

# This next command installs the latest VisualStudio installer that lets you get specific versions of the build
# Microsoft has replaced the 2015 and 2017 installer links with this one, and we can still use it to install the 2015 and 2017 components

choco install visualstudio2019buildtools --package-parameters "--add Microsoft.VisualStudio.Component.VC.140 --passive --locale en-US --add Microsoft.VisualStudio.Component.Windows10SDK.$($PSVersionTable.BuildVersion.Build) --no-includeRecommended" -y --timeout 0

# Usually need the "unlimited" timeout aka "0" because Visual Studio Installer takes forever

# Tool portion
# Microsoft.VisualStudio.Product.BuildTools
# Component portion(s)
# Microsoft.VisualStudio.Component.VC.140
# Win10SDK needs to match your current Win10 build version
# $($PSVersionTable.BuildVersion.Build)
# Microsoft.VisualStudio.Component.Windows10SDK.$($PSVersionTable.BuildVersion.Build)

# Because VS2019 Build Tools are dumb, need to manually link a couple files between the SDK and the VC++ dirs
# You may need to tweak the version here, but it has been updated to be as dynamic as possible 
# Use an elevated Powershell or elevated cmd prompt (if using cmd.exe just use the bits after /c)
cmd /c mklink "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\rc.exe" "C:\Program Files (x86)\Windows Kits\10\bin\$($PSVersionTable.BuildVersion.Major).$($PSVersionTable.BuildVersion.Minor).$($PSVersionTable.BuildVersion.Build).0\x64\rc.exe"

cmd /c mklink "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\rcdll.dll" "C:\Program Files (x86)\Windows Kits\10\bin\$($PSVersionTable.BuildVersion.Major).$($PSVersionTable.BuildVersion.Minor).$($PSVersionTable.BuildVersion.Build).0\x64\rcdll.dll"

Once you have this installed, you should reboot. I've occasionally had things work without a reboot, but your pip install commands will work best if you reboot first.

Now you can pip install pipenv or pip install complex-package and should be good to go.

Array traversal cheatsheet in JavaScript

Given an array, you can traverse it one of the many ways as follows.

1. Classic for loop

const myArray = ['Hello', 'World'];

for (let i = 0; i < myArray.length; i++) {
  console.log(myArray[i]);
}

2. for...of

const myArray = ['Hello', 'World'];

for (const item of myArray) {
  console.log(item);
}

3. Array.prototype.forEach()

const myArray = ['Hello', 'World'];

myArray.forEach(item => {
  console.log(item);
});

4. while loop

const myArray = ['Hello', 'World'];
let i = 0;

while (i < myArray.length) {
  console.log(myArray[i]);
  i++;
}

5. do...while loop

const myArray = ['Hello', 'World'];
let i = 0;

do {
  console.log(myArray[i]);
  i++;
} while (i < myArray.length);

6. Queue style

const myArray = ['Hello', 'World'];


while (myArray.length) {
  console.log(myArray.shift());
}

7. Stack style

Note: The list is printed reverse in this one.

const myArray = ['Hello', 'World'];

while (myArray.length) {
  console.log(myArray.pop());
}

I used the Multiple SCMs Plugin in conjunction with the Git Plugin successfully with Jenkins.

The best bet is to start off with tel: which works on all mobiles

Then put in this code, which will only run when on a desktop, and only when a link is clicked.

I'm using http://detectmobilebrowsers.com/ to detect mobile browsers, you can use whatever method you prefer

if (!jQuery.browser.mobile) {
    jQuery('body').on('click', 'a[href^="tel:"]', function() {
            jQuery(this).attr('href', 
                jQuery(this).attr('href').replace(/^tel:/, 'callto:'));
    });
}

So basically you cover all your bases.

tel: works on all phones to open the dialer with the number

callto: works on your computer to connect to skype from firefox, chrome

Here is a helper class I use often, in case any one ever comes back to this thread (I wanted to share it).

I use this for the simplicity of porting it into projects ready to use:

public class CSVHelper : List<string[]>
{
  protected string csv = string.Empty;
  protected string separator = ",";

  public CSVHelper(string csv, string separator = "\",\"")
  {
    this.csv = csv;
    this.separator = separator;

    foreach (string line in Regex.Split(csv, System.Environment.NewLine).ToList().Where(s => !string.IsNullOrEmpty(s)))
    {
      string[] values = Regex.Split(line, separator);

      for (int i = 0; i < values.Length; i++)
      {
        //Trim values
        values[i] = values[i].Trim('\"');
      }

      this.Add(values);
    }
  }
}

And use it like:

public List<Person> GetPeople(string csvContent)
{
  List<Person> people = new List<Person>();
  CSVHelper csv = new CSVHelper(csvContent);
  foreach(string[] line in csv)
  {
    Person person = new Person();
    person.Name = line[0];
    person.TelephoneNo = line[1];
    people.Add(person);
  }
  return people;
}

[Updated csv helper: bug fixed where the last new line character created a new line]

After viewing and changed the properties to DocumentFormat.OpenXml, I also had to change the Specific Version to false.

it "should call 'bar' with appropriate arguments" do
  expect(subject).to receive(:bar).with("an argument I want")
  subject.foo
end

Well in general:

List<String> names = new ArrayList<String>();
names.add("john");
names.add("ann");

String[] namesArr = new String[names.size()];
for (int i = 0; i < names.size(); i++) {
    namesArr[i] = names.get(i);  
}

Or better yet, using built in:

List<String> names = new ArrayList<String>();
String[] namesArr = names.toArray(new String[names.size()]);

You could just get the input value in the onclick-event like so:

onclick="execute(document.getElementById('textbox1').value);"

You would of course have to add an id to your textbox

Here is the code by AbacusUtil

Map<Integer, String> map = N.asMap(1, "one", 2, "two");
// Or for Immutable map 
ImmutableMap<Integer, String> = ImmutableMap.of(1, "one", 2, "two");

Just came across this message but in c# code. Not sure if it's relevant (exactly the same error message though).

I was debugging the code with breakpoints and expanded some collections through private members while debugger was at a breakpoint. Having re-run the code without digging through structures made the error message go away. It seems like the act of looking into private lazy-loaded collections has made NHibernate load things that were not supposed to be loaded at that time (because they were in private members).

The code itself is wrapped in a fairly complicated transaction that can update large number of records and many dependencies as part of that transaction (import process).

Hopefully a clue to anyone else who comes across the issue.

Just came across this new tool in hacker news.

From their page - "Nuitka is a good replacement for the Python interpreter and compiles every construct that CPython 2.6, 2.7, 3.2 and 3.3 offer. It translates the Python into a C++ program that then uses "libpython" to execute in the same way as CPython does, in a very compatible way."
