There is a GUI tool available, ASoft .NET Version Detector, which has always proven highly reliable. It can create XML files by specifying the file name of the XML output on the command line.

You could use this for automation. It is a tiny program, written in a non-.NET dependent language and does not require installation.

All of todays browsers use at least version 1.5:
http://en.wikipedia.org/wiki/ECMAScript#Dialect

Concerning your tutorial site, the information there seems to be extremely outdated, I beg you to head over to MDC and read their Guide:
https://developer.mozilla.org/en/JavaScript/Guide

You may still want to watch out for features which require version 1.6 or above, as this might give Internet Explorer some troubles.

Hey I got this error resolved by following the steps

• first I uninstalled python 3.8.6 (latest version)
• then I installed python 2.7.1 (any Python 2 version will work, but not much older and this is recommended)
• then I added c:\python27 to environment variables
• my OS is windows, so I followed this link
• It worked

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

You need to pass your data in the request body as a raw string rather than FormUrlEncodedContent. One way to do so is to serialize it into a JSON string:

var json = JsonConvert.SerializeObject(data); // or JsonSerializer.Serialize if using System.Text.Json

Now all you need to do is pass the string to the post method.

var stringContent = new StringContent(json, UnicodeEncoding.UTF8, "application/json"); // use MediaTypeNames.Application.Json in Core 3.0+ and Standard 2.1+

var client = new HttpClient();
var response = await client.PostAsync(uri, stringContent);

I got into a really silly state, I doubt anyone else will find this useful.... but just in case

git ls-remote origin
0d2ab882d0dd5a6db93d7ed77a5a0d7b258a5e1b        HEAD
6f96ad0f97ee832ee16007d865aac9af847c1ef6        refs/heads/HEAD
0d2ab882d0dd5a6db93d7ed77a5a0d7b258a5e1b        refs/heads/master

which I eventually fixed with

git push origin :HEAD

You can find an introduction to file dialogs in the Java Tutorials. Java2s also has some example code.

Try printing out this way

printf("%%");

Sometimes when we do these steps:

 alter table my_table drop constraint my_pk; 
 alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

The last statement fails with

ORA-00955 "name is already used by an existing object"

Oracle usually creates an unique index with the same name my_pk. In such a case you can drop the unique index or rename it based on whether the constraint is still relevant.

You can combine the dropping of primary key constraint and unique index into a single sql statement:

alter table my_table drop constraint my_pk drop index; 

check this: ORA-00955 "name is already used by an existing object"

'JavaType' works !! I was trying to unmarshall (deserialize) a List in json String to ArrayList java Objects and was struggling to find a solution since days.
Below is the code that finally gave me solution. Code:

JsonMarshallerUnmarshaller<T> {
    T targetClass;

    public ArrayList<T> unmarshal(String jsonString) {
        ObjectMapper mapper = new ObjectMapper();

        AnnotationIntrospector introspector = new JacksonAnnotationIntrospector();
        mapper.getDeserializationConfig()
            .withAnnotationIntrospector(introspector);

        mapper.getSerializationConfig()
            .withAnnotationIntrospector(introspector);
        JavaType type = mapper.getTypeFactory().
            constructCollectionType(
                ArrayList.class, 
                targetclass.getClass());

        try {
            Class c1 = this.targetclass.getClass();
            Class c2 = this.targetclass1.getClass();
            ArrayList<T> temp = (ArrayList<T>) 
                mapper.readValue(jsonString,  type);
            return temp ;
        } catch (JsonParseException e) {
            e.printStackTrace();
        } catch (JsonMappingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null ;
    }  
}

This is an old question, but is still regularly viewed/needed. I want to post to caution readers like me that whitespace as mentioned in the OP's question is not the same as Regex's definition, to include newlines, tabs, and space characters -- Git asks you to be explicit. See some options here: https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration

As stated, git diff -b or git diff --ignore-space-change will ignore spaces at line ends. If you desire that setting to be your default behavior, the following line adds that intent to your .gitconfig file, so it will always ignore the space at line ends:

git config --global core.whitespace trailing-space

In my case, I found this question because I was interested in ignoring "carriage return whitespace differences", so I needed this:

git diff --ignore-cr-at-eol or git config --global core.whitespace cr-at-eol from here.

You can also make it the default only for that repo by omitting the --global parameter, and checking in the settings file for that repo. For the CR problem I faced, it goes away after check-in if warncrlf or autocrlf = true in the [core] section of the .gitconfig file.

Note This answer only applies to version 2.x of Vue. Version 3 has lifted this restriction.

You have two root elements in your template.

<div class="form-group">
  ...
</div>
<div class="col-md-6">
  ...
</div>

And you need one.

<div>
    <div class="form-group">
      ...
    </div>

    <div class="col-md-6">
      ...
    </div>
</div>

Essentially in Vue you must have only one root element in your templates.

mysqli is the enhanced version of mysql.

PDO extension defines a lightweight, consistent interface for accessing databases in PHP. Each database driver that implements the PDO interface can expose database-specific features as regular extension functions.

npm --depth 9999 update fixed the issue for me--apparently because package-lock.json was insisting on the outdated versions.

SqlConnection c = new SqlConnection(@"Data Source=localhost; 
                           Initial Catalog=Northwind; Integrated Security=True");

I struggled with this for a few hours today because all of these answers are kind of out of date now what with MDC and the new theming capabilities I just could not see how to override app:titleTextColor app wide as a style.

The answer is that titleTextColor is available in the styles.xml is you are overriding something that inherits from Widget.AppCompat.Toolbar. Today I think the best choice is supposed to be Widget.MaterialComponents.Toolbar:

<style name="Widget.LL.Toolbar" parent="@style/Widget.MaterialComponents.Toolbar">
     <item name="titleTextAppearance">@style/TextAppearance.LL.Toolbar</item>
     <item name="titleTextColor">@color/white</item>
     <item name="android:background">?attr/colorSecondary</item>
</style>

<style name="TextAppearance.LL.Toolbar" parent="@style/TextAppearance.Widget.AppCompat.Toolbar.Title">
     <item name="android:textStyle">bold</item>
</style>

And in your app theme, specify the toolbarStyle:

<item name="toolbarStyle">@style/Widget.LL.Toolbar</item>

Now you can leave the xml where you specify the tool bar unchanged. For a long time I thought changing the android:textColor in the toolbar title text appearance should be working, but for some reason it does not.

The 'C network library' offers functions to handle endian'ness. Namely htons(), htonl(), ntohs() and ntohl() ...where n is "network" (ie. big-endian) and h is "host" (ie. the endian'ness of the machine running the code).

These apparent 'functions' are (commonly) defined as macros [see <netinet/in.h>], so there is no runtime overhead for using them.

The following macros use these 'functions' to evaluate endian'ness.

#include <arpa/inet.h>
#define  IS_BIG_ENDIAN     (1 == htons(1))
#define  IS_LITTLE_ENDIAN  (!IS_BIG_ENDIAN)

In addition:

The only time I ever need to know the endian'ness of a system is when I write-out a variable [to a file/other] which may be read-in by another system of unknown endian'ness (for cross-platform compatability) ...In cases such as these, you may prefer to use the endian functions directly:

#include <arpa/inet.h>

#define JPEG_MAGIC  (('J'<<24) | ('F'<<16) | ('I'<<8) | 'F')

// Result will be in 'host' byte-order
unsigned long  jpeg_magic = JPEG_MAGIC;

// Result will be in 'network' byte-order (IE. Big-Endian/Human-Readable)
unsigned long  jpeg_magic = htonl(JPEG_MAGIC);

Using like might take longer time so use full_text_search:

SELECT * FROM items WHERE MATCH(items.xml) AGAINST ('your_search_word')

WORKING:

$("#ContentPlaceHolder1_txtNombre").keyup(function () {
    var txt = $(this).val();
        $('.column').each(function () {
            $(this).show();
            if ($(this).text().toUpperCase().indexOf(txt.toUpperCase()) == -1) {
                $(this).hide();
            }
        });
    //}
});

Unicode Property Escapes are among the features of ES2018.

Basic Usage

With Unicode Property Escapes, you can match a letter from any language with the following simple regular expression:

/\p{Letter}/u

Or with the shorthand, even terser:

/\p{L}/u

Matching Words

Regarding the question's concrete use case (matching words), note that you can use Unicode Property Escapes in character classes, making it easy to match letters together with other word-characters like hyphens:

/[\p{L}-]/u

Stitching it all together, you could match words of all^[1] languages with this beautifully short RegEx:

/[\p{L}-]+/ug

Example (shamelessly plugged from the answer above):

'Düsseldorf, Köln, ??????, ???, ??????? !@#$'.match(/[\p{L}-]+/ug)

// ["Düsseldorf", "Köln", "??????", "???", "???????"]

^[1] Note that I'm not an expert on languages. You may still want to do your own research regarding other characters that might be parts of words besides letters and hyphens.

Browser Support

This feature is available in all major evergreen browsers.

Transpiling

If support for older browsers is needed, Unicode Property Escapes can be transpiled to ES5 with a tool called regexpu. There's an online demo available here. As you can see in the demo, you can in fact match non-latin letters today with the following (horribly long) ES5 regular expression:

If you're using Babel, there's also a regexpu-powered plugin for that (Babel v6 plugin, Babel v7 plugin).

Please care to update the answer as all of the above fails to impress google pagespeed insights now.

According to Google this is how you should implement async loading of Css

 < noscript id="deferred-styles" >
        < link rel="stylesheet" type="text/css" href="small.css"/ >
    < /noscript >

<script>
  var loadDeferredStyles = function() {
    var addStylesNode = document.getElementById("deferred-styles");
    var replacement = document.createElement("div");
    replacement.innerHTML = addStylesNode.textContent;
    document.body.appendChild(replacement)
    addStylesNode.parentElement.removeChild(addStylesNode);
  };
  var raf = window.requestAnimationFrame || window.mozRequestAnimationFrame ||
      window.webkitRequestAnimationFrame || window.msRequestAnimationFrame;
  if (raf) raf(function() { window.setTimeout(loadDeferredStyles, 0); });
  else window.addEventListener('load', loadDeferredStyles);
</script>

I have the same error the result of command :

file hadoop-2.7.2.tar.gz

is hadoop-2.7.2.tar.gz: HTML document, ASCII text

the reason that the file is not gzip format due to problem in download or other.

Starting from freemarker 2.3.7, you can use this syntax :

${(object.attribute)!}

or, if you want display a default text when the attribute is null :

${(object.attribute)!"default text"}

The JVM will start with memory useage at the initial heap level. If the maxheap is higher, it will grow to the maxheap size as memory requirements exceed it's current memory.

So,

• -Xms512m -Xmx512m

JVM starts with 512 M, never resizes.

• -Xms64m -Xmx512m

JVM starts with 64M, grows (up to max ceiling of 512) if mem. requirements exceed 64.

If you already have a table pre_loaded_tbl with some data. You can use a trick to load the data into your table with following query

INSERT INTO TABLE tweet_table 
  SELECT  "my_data" AS my_column 
    FROM   pre_loaded_tbl 
   LIMIT   5;

Also please note that "my_data" is independent of any data in the pre_loaded_tbl. You can select any data and write any column name (here my_data and my_column). Hive does not require it to have same column name. However structure of select statement should be same as that of your tweet_table. You can use limit to determine how many times you can insert into the tweet_table.

However if you haven't' created any table, you will have to load the data using file copy or load data commands in above answers.

Prefer <appSettings> to <customUserSetting> section. It is much easier to read AND write with (Web)ConfigurationManager. ConfigurationSection, ConfigurationElement and ConfigurationElementCollection require you to derive custom classes and implement custom ConfigurationProperty properties. Way too much for mere everyday mortals IMO.

Here is an example of reading and writing to web.config:

using System.Web.Configuration;
using System.Configuration;

Configuration config = WebConfigurationManager.OpenWebConfiguration("/");
string oldValue = config.AppSettings.Settings["SomeKey"].Value;
config.AppSettings.Settings["SomeKey"].Value = "NewValue";
config.Save(ConfigurationSaveMode.Modified);

Before:

<appSettings>
  <add key="SomeKey" value="oldValue" />
</appSettings>

After:

<appSettings>
  <add key="SomeKey" value="newValue" />
</appSettings>

There is no Text property in the WPF RichTextBox control. Here is one way to get all of the text out:

TextRange range = new TextRange(myRTB.Document.ContentStart, myRTB.Document.ContentEnd);

string allText = range.Text;

I would recommend using the visual designer built into VS2008, as updating the dbml also updates the code that is generated for you. Modifying the dbml outside of the visual designer would result in the underlying code being out of sync.

Your code is correct. Kindly mark small correction.

#rightcolumn {
     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;
}

I assume (heh) you meant --assume-unchanged, since I don't see any --assume-changed option. The inverse of --assume-unchanged is --no-assume-unchanged.

window.onresize = function() {
    // your code
};

You can use the spread operator to convert Map.keys() iterator in an Array.

let myMap = new Map().set('a', 1).set('b', 2).set(983, true)_x000D_
let keys = [...myMap.keys()]_x000D_
console.log(keys)

Scanner's buffer full when we take a input string through scan.nextLine(); so it skips the input next time . So solution is that we can create a new object of Scanner , the name of the object can be same as previous object......

Angular only points to src/assets folder, nothing else is public to access via url so you should use full path

 this.fullImagePath = '/assets/images/therealdealportfoliohero.jpg'

Or

 this.fullImagePath = 'assets/images/therealdealportfoliohero.jpg'

This will only work if the base href tag is set with /

You can also add other folders for data in angular/cli. All you need to modify is angular-cli.json

"assets": [
 "assets",
 "img",
 "favicon.ico",
 ".htaccess"
]

Note in edit : Dist command will try to find all attachments from assets so it is also important to keep the images and any files you want to access via url inside assets, like mock json data files should also be in assets.

I use redbot, a great tool to see php version, but also many other useful infos like headers, encoding, keepalive and many more, try it on

I loveit !

I also upvote Neil answer : curl -I http://websitename.com

Going back to the original question (4 years later), rather than rebuilding your own section header, iOS can simply call you (with willDisplayHeaderView:forSection:) right after it's built the default one. For example, I wanted to add a graph button on right edge of section header:

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    UITableViewHeaderFooterView * header = (UITableViewHeaderFooterView *) view;
    if (header.contentView.subviews.count >  0) return; //in case of reuse
    CGFloat rightEdge = CGRectGetMaxX(header.contentView.bounds);
    UIButton * button = [[UIButton alloc] initWithFrame:CGRectMake(rightEdge - 44, 0, 44, CGRectGetMaxY(header.contentView.bounds))];
    [button setBackgroundImage:[UIImage imageNamed:@"graphIcon"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(graphButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [view addSubview:button];
}

Open below file C:\xampp\htdocs\project\common\config\params-local.php

Before your code:

<?php

return [


];

after your code:

<?php
yii::setAlias('@path1', 'localhost/foodbam/backend/web');

return [


];

I agree with John on wrapping the sleep function. You could also use this wrapped sleep function to implement a pause function in lua (which would simply sleep then check to see if a certain condition has changed every so often). An alternative is to use hooks.

I'm not exactly sure what you mean with your third bulletpoint (don't commands usually complete before the next is executed?) but hooks may be able to help with this also.

See: Question: How can I end a Lua thread cleanly? for an example of using hooks.

yes, %c will print a single char:

printf("%c", 'h');

also, putchar/putc will work too. From "man putchar":

#include <stdio.h>

int fputc(int c, FILE *stream);
int putc(int c, FILE *stream);
int putchar(int c);

* fputc() writes the character c, cast to an unsigned char, to stream.
* putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once.
* putchar(c); is equivalent to putc(c,stdout).

EDIT:

Also note, that if you have a string, to output a single char, you need get the character in the string that you want to output. For example:

const char *h = "hello world";
printf("%c\n", h[4]); /* outputs an 'o' character */

The main point of the differences as pointed out @BizApps is that Load event happens right after the ViewState is populated while PreRender event happens later, right before Rendering phase, and after all individual children controls' action event handlers are already executing. Therefore, any modifications done by the controls' actions event handler should be updated in the control hierarchy during PreRender as it happens after.

Actually speaking, when I tried this, it worked only when I set the action and method value for the form. Funny how it works though!

This is my solution for the problem. You can 'implement' multiple interfaces by overriding one Interface with another.

class MyInterface {
    // Declare your JS doc in the Interface to make it acceable while writing the Class and for later inheritance
    /**
     * Gives the sum of the given Numbers
     * @param {Number} a The first Number
     * @param {Number} b The second Number
     * @return {Number} The sum of the Numbers
     */
    sum(a, b) { this._WARNING('sum(a, b)'); }


    // delcare a warning generator to notice if a method of the interface is not overridden
    // Needs the function name of the Interface method or any String that gives you a hint ;)
    _WARNING(fName='unknown method') {
        console.warn('WARNING! Function "'+fName+'" is not overridden in '+this.constructor.name);
    }
}

class MultipleInterfaces extends MyInterface {
    // this is used for "implement" multiple Interfaces at once
    /**
     * Gives the square of the given Number
     * @param {Number} a The Number
     * @return {Number} The square of the Numbers
     */
    square(a) { this._WARNING('square(a)'); }
}

class MyCorrectUsedClass extends MyInterface {
    // You can easy use the JS doc declared in the interface
    /** @inheritdoc */
    sum(a, b) {
        return a+b;
    }
}
class MyIncorrectUsedClass extends MyInterface {
    // not overriding the method sum(a, b)
}

class MyMultipleInterfacesClass extends MultipleInterfaces {
    // nothing overriden to show, that it still works
}


let working = new MyCorrectUsedClass();

let notWorking = new MyIncorrectUsedClass();

let multipleInterfacesInstance = new MyMultipleInterfacesClass();

// TEST IT

console.log('working.sum(1, 2) =', working.sum(1, 2));
// output: 'working.sum(1, 2) = 3'

console.log('notWorking.sum(1, 2) =', notWorking.sum(1, 2));
// output: 'notWorking.sum(1, 2) = undefined'
// but also sends a warn to the console with 'WARNING! Function "sum(a, b)" is not overridden in MyIncorrectUsedClass'

console.log('multipleInterfacesInstance.sum(1, 2) =', multipleInterfacesInstance.sum(1, 2));
// output: 'multipleInterfacesInstance.sum(1, 2) = undefined'
// console warn: 'WARNING! Function "sum(a, b)" is not overridden in MyMultipleInterfacesClass'

console.log('multipleInterfacesInstance.square(2) =', multipleInterfacesInstance.square(2));
// output: 'multipleInterfacesInstance.square(2) = undefined'
// console warn: 'WARNING! Function "square(a)" is not overridden in MyMultipleInterfacesClass'

EDIT:

I improved the code so you now can simply use implement(baseClass, interface1, interface2, ...) in the extend.

/**
* Implements any number of interfaces to a given class.
* @param cls The class you want to use
* @param interfaces Any amount of interfaces separated by comma
* @return The class cls exteded with all methods of all implemented interfaces
*/
function implement(cls, ...interfaces) {
    let clsPrototype = Object.getPrototypeOf(cls).prototype;
    for (let i = 0; i < interfaces.length; i++) {
        let proto = interfaces[i].prototype;
        for (let methodName of Object.getOwnPropertyNames(proto)) {
            if (methodName!== 'constructor')
                if (typeof proto[methodName] === 'function')
                    if (!clsPrototype[methodName]) {
                        console.warn('WARNING! "'+methodName+'" of Interface "'+interfaces[i].name+'" is not declared in class "'+cls.name+'"');
                        clsPrototype[methodName] = proto[methodName];
                    }
        }
    }
    return cls;
}

// Basic Interface to warn, whenever an not overridden method is used
class MyBaseInterface {
    // declare a warning generator to notice if a method of the interface is not overridden
    // Needs the function name of the Interface method or any String that gives you a hint ;)
    _WARNING(fName='unknown method') {
        console.warn('WARNING! Function "'+fName+'" is not overridden in '+this.constructor.name);
    }
}


// create a custom class
/* This is the simplest example but you could also use
*
*   class MyCustomClass1 extends implement(MyBaseInterface) {
*       foo() {return 66;}
*   }
*
*/
class MyCustomClass1 extends MyBaseInterface {
    foo() {return 66;}
}

// create a custom interface
class MyCustomInterface1 {
     // Declare your JS doc in the Interface to make it acceable while writing the Class and for later inheritance

    /**
     * Gives the sum of the given Numbers
     * @param {Number} a The first Number
     * @param {Number} b The second Number
     * @return {Number} The sum of the Numbers
     */
    sum(a, b) { this._WARNING('sum(a, b)'); }
}

// and another custom interface
class MyCustomInterface2 {
    /**
     * Gives the square of the given Number
     * @param {Number} a The Number
     * @return {Number} The square of the Numbers
     */
    square(a) { this._WARNING('square(a)'); }
}

// Extend your custom class even more and implement the custom interfaces
class AllInterfacesImplemented extends implement(MyCustomClass1, MyCustomInterface1, MyCustomInterface2) {
    /**
    * @inheritdoc
    */
    sum(a, b) { return a+b; }

    /**
    * Multiplies two Numbers
    * @param {Number} a The first Number
    * @param {Number} b The second Number
    * @return {Number}
    */
    multiply(a, b) {return a*b;}
}


// TEST IT

let x = new AllInterfacesImplemented();

console.log("x.foo() =", x.foo());
//output: 'x.foo() = 66'

console.log("x.square(2) =", x.square(2));
// output: 'x.square(2) = undefined
// console warn: 'WARNING! Function "square(a)" is not overridden in AllInterfacesImplemented'

console.log("x.sum(1, 2) =", x.sum(1, 2));
// output: 'x.sum(1, 2) = 3'

console.log("x.multiply(4, 5) =", x.multiply(4, 5));
// output: 'x.multiply(4, 5) = 20'

Since bootstrap 4 will be out soon I thought I would share a function that supports it (xl is now a thing) and performs minimal jQuery to get the job done.

/**
 * Get the Bootstrap device size
 * @returns {string|boolean} xs|sm|md|lg|xl on success, otherwise false if Bootstrap is not working or installed
 */
function findBootstrapEnvironment() {
    var environments = ['xs', 'sm', 'md', 'lg', 'xl'];
    var $el = $('<span />');
    $el.appendTo($('body'));
    for (var i = environments.length - 1; i >= 0; i--) {
        var env = environments[i];
        $el.addClass('hidden-'+env);
        if ($el.is(':hidden')) {
            $el.remove();
            return env;
        }
    }
    $el.remove();
    return false;
}

Here's how to fix this error when launching Eclipse:

Version 1.6.0_65 of the JVM is not suitable for this product. Version: 1.7 or greater is required.

1. Go and install latest JDK

2. Make sure you have installed 64 bit Eclipse

You need to make sure that you add forward slash before your link to socket.io:

<script src="/socket.io/socket.io.js"></script>

Then in the view/controller just do:

var socket = io.connect()

That should solve your problem.

for example try this :

<a href="http://www.google.com" id="myLink1">open link 1</a><br/> <a href="http://www.youtube.com" id="myLink2">open link 2</a>

    document.getElementById("myLink1").onclick = function() {
    window.open(
    "http://www.facebook.com"
        );
        return false;
      };

      document.getElementById("myLink2").onclick = function() {
    window.open(
    "http://www.yahoo.com"
        );
        return false;
      };

For *nix users who are using SSH:

Make sure the username for your account on your local machine does not differ from the username for the account on the server. Apparently, eGit does not seem to be able to handle this. For example, if your username on your local machine is 'john', and the account you are using on the server is named 'git', egit simply fails to connect (for me anyways). The only work around I have found is to make sure you have identical usernames in both the local machine and the server.

In the current order? I'd say array_slice(). Since it's a built in function it will be faster than looping through the array while keeping track of an incrementing index until N.

1. Click on the Network button
2. Enable capture of network traffic by clicking on the green triangular button in top toolbar
3. Capture some network traffic by interacting with the page
4. Click on DETAILS/Cookies
5. Step through each captured traffic segment; detailed information about cookies will be displayed

You need to check put method in Hash map first as HashSet is backed up by HashMap

1. When you add duplicate value say a String "One" into HashSet,
2. An entry ("one", PRESENT) will get inserted into Hashmap(for all the values added into set, the value will be "PRESENT" which if of type Object)
3. Hashmap adds the entry into Map and returns the value, which is in this case "PRESENT" or null if Entry is not there.
4. Hashset's add method then returns true if the returned value from Hashmap equals null otherwise false which means an entry already exists...

I had a need for an extended version of this: instead of embedding a single number in a string, I needed to generate a series of file names of the form 'file1.pdf', 'file2.pdf' etc. This is how it worked:

['file' + str(i) + '.pdf' for i in range(1,4)]

echo -n 5a | perl -pe 's/([0-9a-f]{2})/chr hex $1/gie'

Note that this won't skip non-hex characters. If you want just the hex (no whitespace from the original string etc):

echo 5a | perl -ne 's/([0-9a-f]{2})/print chr hex $1/gie'

Also, zsh and bash support this natively in echo:

echo -e '\x5a'

for me one case was I just missed to maven update project which caused the same issue

maven update project and try if you see any errors in POM.xml

If for some reason you don't want to use the break instruction (if you think it will disrupt your reading flow next time you will read your programm, for example), you can try the following :

boolean test = true;
for (int i = 0; i < 1220 && test; i++) {
    System.out.println(i);
    if (i == 20) {
        test = false;
    }
 }

The second arg of a for loop is a boolean test. If the result of the test is true, the loop will stop. You can use more than just an simple math test if you like. Otherwise, a simple break will also do the trick, as others said :

for (int i = 0; i < 1220 ; i++) {
    System.out.println(i);
    if (i == 20) {
        break;
    }
 }

I realise I'm late to the party, but I wanted a solution for this that properly handled digit grouping as well as different decimal separators for currencies. As none of these fully covered my use case I wrote my own solution which may be useful to others:

function parsePotentiallyGroupedFloat(stringValue) {
    stringValue = stringValue.trim();
    var result = stringValue.replace(/[^0-9]/g, '');
    if (/[,\.]\d{2}$/.test(stringValue)) {
        result = result.replace(/(\d{2})$/, '.$1');
    }
    return parseFloat(result);
}

This should strip out any non-digits and then check whether there was a decimal point (or comma) followed by two digits and insert the decimal point if needed.

It's worth noting that I aimed this specifically for currency and as such it assumes either no decimal places or exactly two. It's pretty hard to be sure about whether the first potential decimal point encountered is a decimal point or a digit grouping character (e.g., 1.542 could be 1542) unless you know the specifics of the current locale, but it should be easy enough to tailor this to your specific use case by changing \d{2}$ to something that will appropriately match what you expect to be after the decimal point.

check this out: http://hayageek.com/docs/jquery-upload-file.php I've found it accidentally on the net.

Well, yet another option. A typical use case is where you need constant for the HTTP verbs as well as using is string version values.

The example:

int main () {

  VERB a = VERB::GET;
  VERB b = VERB::GET;
  VERB c = VERB::POST;
  VERB d = VERB::PUT;
  VERB e = VERB::DELETE;


  std::cout << a.toString() << std::endl;

  std::cout << a << std::endl;

  if ( a == VERB::GET ) {
    std::cout << "yes" << std::endl;
  }

  if ( a == b ) {
    std::cout << "yes" << std::endl;
  }

  if ( a != c ) {
    std::cout << "no" << std::endl;
  }

}

The VERB class:

// -----------------------------------------------------------
// -----------------------------------------------------------
class VERB {

private:

  // private constants
  enum Verb {GET_=0, POST_, PUT_, DELETE_};

  // private string values
  static const std::string theStrings[];

  // private value
  const Verb value;
  const std::string text;

  // private constructor
  VERB (Verb v) :
  value(v), text (theStrings[v])
  {
    // std::cout << " constructor \n";
  }

public:

  operator const char * ()  const { return text.c_str(); }

  operator const std::string ()  const { return text; }

  const std::string toString () const { return text; }

  bool operator == (const VERB & other) const { return (*this).value == other.value; }

  bool operator != (const VERB & other) const { return ! ( (*this) == other); }

  // ---

  static const VERB GET;
  static const VERB POST;
  static const VERB PUT;
  static const VERB DELETE;

};

const std::string VERB::theStrings[] = {"GET", "POST", "PUT", "DELETE"};

const VERB VERB::GET = VERB ( VERB::Verb::GET_ );
const VERB VERB::POST = VERB ( VERB::Verb::POST_ );
const VERB VERB::PUT = VERB ( VERB::Verb::PUT_ );
const VERB VERB::DELETE = VERB ( VERB::Verb::DELETE_ );
// end of file

I came accross the same problem and solved.

As said before you need to create your custom WebViewClient and override the shouldInterceptRequest method.

WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request)

That method should issue a webView.loadUrl while returning an "empty" WebResourceResponse.

Something like this:

@Override
public boolean shouldInterceptRequest(WebView view, WebResourceRequest request) {

    // Check for "recursive request" (are yor header set?)
    if (request.getRequestHeaders().containsKey("Your Header"))
        return null;

    // Add here your headers (could be good to import original request header here!!!)
    Map<String, String> customHeaders = new HashMap<String, String>();
    customHeaders.put("Your Header","Your Header Value");
    view.loadUrl(url, customHeaders);

    return new WebResourceResponse("", "", null);
}

You can use useHistory hook since react-router v5.1.0.

The useHistory hook gives you access to the history instance that you may use to navigate.

import React from 'react'
import { useHistory } from 'react-router-dom'

export default function SomeComponent() {
  const { push } = useHistory()
  ...
  <button
    type="button"
    onClick={() => push('/some-link')}
  >
    Some link
  </button>
  ...
}

Here's what I use and will only take a few seconds to run:

ffmpeg -i input.mp4 -ss 01:19:27 -to 02:18:51 -c:v copy -c:a copy output.mp4

Reference: https://www.arj.no/2018/05/18/trimvideo

Generated mp4 files could also be used in iMovie. More info related to get the full duration using get_duration(input_video) modele.

If you want to concatenate multiple cut scenes you can use following Python script:

#!/usr/bin/env python3

import subprocess


def get_duration(input_video):
    cmd = ["ffprobe", "-i", input_video, "-show_entries", "format=duration",
           "-v", "quiet", "-sexagesimal", "-of", "csv=p=0"]
    return subprocess.check_output(cmd).decode("utf-8").strip()


if __name__ == "__main__":
    name = "input.mkv"

    times = []
    times.append(["00:00:00", "00:00:10"])
    times.append(["00:06:00", "00:07:00"])

    # times = [["00:00:00", get_duration(name)]]

    if len(times) == 1:
        time = times[0]
        cmd = ["ffmpeg", "-i", name, "-ss", time[0], "-to", time[1], "-c:v", "copy", "-c:a", "copy", "output.mp4"]
        subprocess.check_output(cmd)
    else:
        open('concatenate.txt', 'w').close()
        for idx, time in enumerate(times):
            output_filename = f"output{idx}.mp4"
            cmd = ["ffmpeg", "-i", name, "-ss", time[0], "-to", time[1], "-c:v", "copy", "-c:a", "copy", output_filename]
            subprocess.check_output(cmd)

            with open("concatenate.txt", "a") as myfile:
                myfile.write(f"file {output_filename}\n")

        cmd = ["ffmpeg", "-f", "concat", "-i", "concatenate.txt", "-c", "copy", "output.mp4"]
        output = subprocess.check_output(cmd).decode("utf-8").strip()

Example script will cut and merge scenes in between 00:00:00 - 00:00:10 and 00:06:00 - 00:07:00.

If you want to cut the complete video (in case if you want to convert mkv format into mp4) just uncomment the following line:

# times = [["00:00:00", get_duration(name)]]

Walkthrough: Using Multiple Programming Languages in a Web Site Project http://msdn.microsoft.com/en-us/library/ms366714.aspx

By default, the App_Code folder does not allow multiple programming languages. However, in a Web site project you can modify your folder structure and configuration settings to support multiple programming languages such as Visual Basic and C#. This allows ASP.NET to create multiple assemblies, one for each language. For more information, see Shared Code Folders in ASP.NET Web Projects. Developers commonly include multiple programming languages in Web applications to support multiple development teams that operate independently and prefer different programming languages.

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

same browsers may return string for border width, in this parseInt will return NaN so make sure you parse value to int properly.

        var getInt = function (string) {
            if (typeof string == "undefined" || string == "")
                return 0;
            var tempInt = parseInt(string);

            if (!(tempInt <= 0 || tempInt > 0))
                return 0;
            return tempInt;
        }

        var liWidth = $(this).width();
        liWidth += getInt($(this).css("padding-left"));
        liWidth += getInt($(this).css("padding-right"));
        liWidth += getInt($(this).css("border-left-width"));
        liWidth += getInt($(this).css("border-right-width"));

Since it seems like nobody has pointed this on out yet:

url = "www.example.com"
new_url = url[:url.rfind(".")]

This should be more efficient than the methods using split() as no new list object is created, and this solution works for strings with several dots.

There's a oneliner for this one.

You can simply run,

docker run -v /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war:/usr/local/tomcat/webapps/myapp.war -it -p 8080:8080 tomcat

This will copy the war file to webapps directory and get your app running in no time.

You can find === and !== operators in several other dynamically-typed languages as well. It always means that the two values are not only compared by their "implied" value (i.e. either or both values might get converted to make them comparable), but also by their original type.

That basically means that if 0 == "0" returns true, 0 === "0" will return false because you are comparing a number and a string. Similarly, while 0 != "0" returns false, 0 !== "0" returns true.

Following will give you the selected content as well as updating the clipboard.

Bind the element id with copy event and then get the selected text. You could replace or modify the text. Get the clipboard and set the new text. To get the exact formatting you need to set the type as "text/hmtl". You may also bind it to the document instead of element.

document.querySelector('element').bind('copy', function(event) {
  var selectedText = window.getSelection().toString(); 
  selectedText = selectedText.replace(/\u200B/g, "");

  clipboardData = event.clipboardData || window.clipboardData || event.originalEvent.clipboardData;
  clipboardData.setData('text/html', selectedText);

  event.preventDefault();
});

To supplement other answers, it could also be due to the auto-minification of your php script if you are using an ftp client like FileZilla. Ensure that the transfer type is set to Binary and not ASCII or auto. The ASCII or auto transfer type can minify your php code leading to this error.

Or, if you need to access the element that has that property and it does not use an id, you could go this route:

$("img").each(function () {
        if ($(this).css("float") == "left") { $(this).addClass("left"); }
        if ($(this).css("float") == "right") { $(this).addClass("right"); }
    })

Here is my solution I use for my app.

I have several asset folder with css / js / img anf font files.

The application gets all filenames and looks if a file with this name is requested. If yes, it loads it from asset folder.

//get list of files of specific asset folder
        private ArrayList listAssetFiles(String path) {

            List myArrayList = new ArrayList();
            String [] list;
            try {
                list = getAssets().list(path);
                for(String f1 : list){
                    myArrayList.add(f1);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            return (ArrayList) myArrayList;
        }

        //get mime type by url
        public String getMimeType(String url) {
            String type = null;
            String extension = MimeTypeMap.getFileExtensionFromUrl(url);
            if (extension != null) {
                if (extension.equals("js")) {
                    return "text/javascript";
                }
                else if (extension.equals("woff")) {
                    return "application/font-woff";
                }
                else if (extension.equals("woff2")) {
                    return "application/font-woff2";
                }
                else if (extension.equals("ttf")) {
                    return "application/x-font-ttf";
                }
                else if (extension.equals("eot")) {
                    return "application/vnd.ms-fontobject";
                }
                else if (extension.equals("svg")) {
                    return "image/svg+xml";
                }
                type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
            }
            return type;
        }

        //return webresourceresponse
        public WebResourceResponse loadFilesFromAssetFolder (String folder, String url) {
            List myArrayList = listAssetFiles(folder);
            for (Object str : myArrayList) {
                if (url.contains((CharSequence) str)) {

For those experimenting with this in phpMyAdmin, just a word:

phpMyAdmin appears to have a few problems with USING. For the record this is phpMyAdmin run on Linux Mint, version: "4.5.4.1deb2ubuntu2", Database server: "10.2.14-MariaDB-10.2.14+maria~xenial - mariadb.org binary distribution".

I have run SELECT commands using JOIN and USING in both phpMyAdmin and in Terminal (command line), and the ones in phpMyAdmin produce some baffling responses:

1) a LIMIT clause at the end appears to be ignored.
2) the supposed number of rows as reported at the top of the page with the results is sometimes wrong: for example 4 are returned, but at the top it says "Showing rows 0 - 24 (2503 total, Query took 0.0018 seconds.)"

Logging on to mysql normally and running the same queries does not produce these errors. Nor do these errors occur when running the same query in phpMyAdmin using JOIN ... ON .... Presumably a phpMyAdmin bug.

In Python 3.6

If you want to always prune when you fetch, I can suggest to use Aliases.

Just type git config -e to open your editor and change the configuration for a specific project and add a section like

[alias]
pfetch = fetch --prune   

the when you fetch with git pfetch the prune will be done automatically.

On Firefox for Ubuntu, just using

    input[type='number'] {
    -moz-appearance:textfield;
}

did the trick for me.

Adding

input::-webkit-outer-spin-button,
input::-webkit-inner-spin-button {
    -webkit-appearance: none;
}

Would lead me to

Unknown pseudo-class or pseudo-element ‘-webkit-outer-spin-button’. Ruleset ignored due to bad selector.

everytime I tried. Same for the inner spin button.

Took me a while to read through the above. This was the answer for me:

import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

g = sns.lmplot(
    x="total_bill", 
    y="tip", 
    hue="smoker", 
    data=tips,  
    legend=False
)

plt.legend(title='Smoker', loc='upper left', labels=['Hell Yeh', 'Nah Bruh'])
plt.show(g)

Reference this for more arguments: matplotlib.pyplot.legend

Do you want to roll back your repo to that state, or you just want your local repo to look like that?

If you reset --hard, it will make your local code and local history be just like it was at that commit. But if you wanted to push this to someone else who has the new history, it would fail:

git reset --hard c14809fa

And if you reset --soft, it will move your HEAD to where they were , but leave your local files etc. the same:

git reset --soft c14809fa

So what exactly do you want to do with this reset?

Edit -

You can add "tags" to your repo.. and then go back to a tag. But a tag is really just a shortcut to the sha1.

You can tag this as TAG1.. then a git reset --soft c14809fa, git reset --soft TAG1, or git reset --soft c14809fafb08b9e96ff2879999ba8c807d10fb07 would all do the same thing.

you can load images in your html somewhere using css display:none; rule, then show them when you want with js or jquery

don't use js or jquery functions to preload is just a css rule Vs many lines of js to be executed

example: Html

<img src="someimg.png" class="hide" alt=""/>

Css:

.hide{
display:none;
}

jQuery:

//if want to show img 
$('.hide').show();
//if want to hide
$('.hide').hide();

Preloading images by jquery/javascript is not good cause images takes few milliseconds to load in page + you have milliseconds for the script to be parsed and executed, expecially then if they are big images, so hiding them in hml is better also for performance, cause image is really preloaded without beeing visible at all, until you show that!

You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.

Split Function Works Great when you are getting One String containing multiple values but when you are passing Multiple values you need to do something like this....

TABLE TYPE

CREATE TYPE dbo.TYPENAME AS TABLE   (     arg int    )  GO 

Stored Procedure to Accept That Type Param

 CREATE PROCEDURE mainValues   @TableParam TYPENAME READONLY  AS     BEGIN     SET NOCOUNT ON;   --Temp table to store split values   declare @tmp_values table (   value nvarchar(255) not null);        --function splitting values     INSERT INTO @tmp_values (value)    SELECT arg FROM @TableParam      SELECT * FROM @tmp_values  --<-- For testing purpose END 

EXECUTE PROC

Declare a variable of that type and populate it with your values.

 DECLARE @Table TYPENAME     --<-- Variable of this TYPE   INSERT INTO @Table                --<-- Populating the variable   VALUES (331),(222),(876),(932)  EXECUTE mainValues @Table   --<-- Stored Procedure Executed  

Result

╔═══════╗ ║ value ║ ╠═══════╣ ║   331 ║ ║   222 ║ ║   876 ║ ║   932 ║ ╚═══════╝

You can use the Y-combinator: (Wikipedia)

// ES5 syntax
var Y = function Y(a) {
  return (function (a) {
    return a(a);
  })(function (b) {
    return a(function (a) {
      return b(b)(a);
    });
  });
};

// ES6 syntax
const Y = a=>(a=>a(a))(b=>a(a=>b(b)(a)));

// If the function accepts more than one parameter:
const Y = a=>(a=>a(a))(b=>a((...a)=>b(b)(...a)));

And you can use it as this:

// ES5
var fn = Y(function(fn) {
  return function(counter) {
    console.log(counter);
    if (counter > 0) {
      fn(counter - 1);
    }
  }
});

// ES6
const fn = Y(fn => counter => {
  console.log(counter);
  if (counter > 0) {
    fn(counter - 1);
  }
});

Can't comment the last answer but the fix is relatively easy. Just set the background color of your opaque canvas:

#canvas1 { background-color: black; } //opaque canvas
#canvas2 { ... } //transparent canvas

I'm not sure but it looks like that the background-color is inherited as transparent from the body.

It depends on which version of Oracle? Older versions require exp (export), newer versions use expdp (data pump); exp was deprecated but still works most of the time.

Before starting, note that Data Pump exports to the server-side Oracle "directory", which is an Oracle symbolic location mapped in the database to a physical location. There may be a default directory (DATA_PUMP_DIR), check by querying DBA_DIRECTORIES:

  SQL> select * from dba_directories;

... and if not, create one

  SQL> create directory DATA_PUMP_DIR as '/oracle/dumps';
  SQL> grant all on directory DATA_PUMP_DIR to myuser;    -- DBAs dont need this grant

Assuming you can connect as the SYSTEM user, or another DBA, you can export any schema like so, to the default directory:

 $ expdp system/manager schemas=user1 dumpfile=user1.dpdmp

Or specifying a specific directory, add directory=<directory name>:

 C:\> expdp system/manager schemas=user1 dumpfile=user1.dpdmp directory=DUMPDIR

With older export utility, you can export to your working directory, and even on a client machine that is remote from the server, using:

 $ exp system/manager owner=user1 file=user1.dmp

Make sure the export is done in the correct charset. If you haven't setup your environment, the Oracle client charset may not match the DB charset, and Oracle will do charset conversion, which may not be what you want. You'll see a warning, if so, then you'll want to repeat the export after setting NLS_LANG environment variable so the client charset matches the database charset. This will cause Oracle to skip charset conversion.

Example for American UTF8 (UNIX):

 $ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Windows uses SET, example using Japanese UTF8:

 C:\> set NLS_LANG=Japanese_Japan.AL32UTF8

More info on Data Pump here: http://docs.oracle.com/cd/B28359_01/server.111/b28319/dp_export.htm#g1022624

One more little tidbit that I just discovered. (This may be so basic that some haven't mentioned it, but it was important for my solution.) The "packages" folder ends up in the same folder as your .sln file.

We moved our .sln file and then fixed all of the paths inside to find the various projects and voila! Our packages folder ended up where we wanted it.

Just use negative margins, in the second div say:

<div style="margin-top: -25px;">

And make sure to set the z-index property to get the layering you want.

This is slightly modified version of Mark Ransom's answer that works if ch could be more than one character in length.

def find(term, ch):
    """Find all places with ch in str
    """
    for i in range(len(term)):
        if term[i:i + len(ch)] == ch:
            yield i

You can also use below code which helps me:

select convert(numeric(10,2), column_name) as Total from TABLE_NAME

where Total is alias of the field you 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]

The solution is mentioned here: iPhone WebKit CSS animations cause flicker.

For your element, you need to set

-webkit-backface-visibility: hidden;

As JavaScript is a client-side language and PHP is a server-side language you would need to physically push the variable to the PHP script, by either including the variable on the page load of the PHP script (script.php?var=test), which really has nothing to do with JavaScript, or by passing the variable to the PHP via an AJAX/AHAH call each time the variable is changed.

If you did want to go down the second path, you'd be looking at XMLHttpRequest, or my preference, jQuerys Ajax calls: http://docs.jquery.com/Ajax

I have something like this :

public static boolean deleteDirectory(File directory) {
    if(directory.exists()){
        File[] files = directory.listFiles();
        if(null!=files){
            for(int i=0; i<files.length; i++) {
                if(files[i].isDirectory()) {
                    deleteDirectory(files[i]);
                }
                else {
                    files[i].delete();
                }
            }
        }
    }
    return(directory.delete());
}

It is the area of the marker. I mean if you have s1 = 1000 and then s2 = 4000, the relation between the radius of each circle is: r_s2 = 2 * r_s1. See the following plot:

plt.scatter(2, 1, s=4000, c='r')
plt.scatter(2, 1, s=1000 ,c='b')
plt.scatter(2, 1, s=10, c='g')

I had the same doubt when I saw the post, so I did this example then I used a ruler on the screen to measure the radii.

Ok, this might be weird. Anyway one of my colleagues had this error and we tried the edit VBA compile whatever. But the thing is, just copy the excel file to the desktop. And it worked. The Excel file was originally in a network drive. This worked, this is my answer to this issue.

Just so for people doing it in SQL server: use STRING_AGG to get similar results.

You might notice using class selector to get value of ASP.NET RadioButton controls is always empty and here is the reason.

You create RadioButton control in ASP.NET as below:

<asp:RadioButton runat="server" ID="rbSingle" GroupName="Type" CssClass="radios" Text="Single" />
<asp:RadioButton runat="server" ID="rbDouble" GroupName="Type" CssClass="radios" Text="Double" />
<asp:RadioButton runat="server" ID="rbTriple" GroupName="Type" CssClass="radios" Text="Triple" />

And ASP.NET renders following HTML for your RadioButton

<span class="radios"><input id="Content_rbSingle" type="radio" name="ctl00$Content$Type" value="rbSingle" /><label for="Content_rbSingle">Single</label></span>
<span class="radios"><input id="Content_rbDouble" type="radio" name="ctl00$Content$Type" value="rbDouble" /><label for="Content_rbDouble">Double</label></span>
<span class="radios"><input id="Content_rbTriple" type="radio" name="ctl00$Content$Type" value="rbTriple" /><label for="Content_rbTriple">Triple</label></span>

For ASP.NET we don't want to use RadioButton control name or id because they can change for any reason out of user's hand (change in container name, form name, usercontrol name, ...) as you can see in code above.

The only remaining feasible way to get the value of the RadioButton using jQuery is using css class as mentioned in this answer to a totally unrelated question as following

$('span.radios input:radio').click(function() {
    var value = $(this).val();
});

rebellion's answer above won't actually work, because to CSS, 'background-position' is actually shorthand for 'background-position-x' and 'background-position-y' so the correct version of his code would be:

$(document).ready(function(){
    $('#submenu li').hover(function(){
        $('#carousel').css('background-position-x', newValueX);
        $('#carousel').css('background-position-y', newValue);
    }, function(){
        $('#carousel').css('background-position-x', oldValueX);
        $('#carousel').css('background-position-y', oldValueY);
    });
});

It took about 4 hours of banging my head against it to come to that aggravating realization.

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:

You will need to use reflection to get the type "TestRunner". Use the Assembly.GetType method.

class Program
{
    static void Main(string[] args)
    {
        Assembly assembly = Assembly.LoadFile(@"C:\dyn.dll");
        Type type = assembly.GetType("TestRunner");
        var obj = (TestRunner)Activator.CreateInstance(type);
        obj.Run();
    }
}

You can achieve this also by using JavaScripts's native method. Its pretty simple and doesn't require any extra library to import.

<input type="text" name="date" placeholder="yyyy-mm-dd" onkeyup="
  var date = this.value;
  if (date.match(/^\d{4}$/) !== null) {
     this.value = date + '-';
  } else if (date.match(/^\d{4}\-\d{2}$/) !== null) {
     this.value = date + '-';
  }" maxlength="10">

There's an Excel OLEDB data provider built into Windows; you can use this to 'query' the Excel sheet via ADO.NET and write the results to a CSV file. There's a small amount of coding required, but you shouldn't need to install anything on the machine.

Using the length of the list would be the fastest solution to check if an index exists:

def index_exists(ls, i):
    return (0 <= i < len(ls)) or (-len(ls) <= i < 0)

This also tests for negative indices, and most sequence types (Like ranges and strs) that have a length.

If you need to access the item at that index afterwards anyways, it is easier to ask forgiveness than permission, and it is also faster and more Pythonic. Use try: except:.

try:
    item = ls[i]
    # Do something with item
except IndexError:
    # Do something without the item

This would be as opposed to:

if index_exists(ls, i):
    item = ls[i]
    # Do something with item
else:
    # Do something without the item

You can change your text or Content or Attribute depend on Screen size: HTML:

<p class="change">Frequently Asked Questions (FAQ)</p>
<p class="change">Frequently Asked Questions </p>

Javascript:

<script>
const changeText = document.querySelector('.change');
function resize() {
  if((window.innerWidth<500)&&(changeText.textContent="Frequently Asked Questions (FAQ)")){
    changeText.textContent="FAQ";
  } else {
    changeText.textContent="Frequently Asked Questions (FAQ)";
  }
}
window.onresize = resize;
</script>

Give Safe User Permission To Use Port 80

Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/

Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port - where port number > 1024.

A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:

sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``

Now, when you tell a Node application that you want it to run on port 80, it will not complain.

There is no direction one way or the other. Not good. gawk implies subtraction, other awks imply field number or subtraction. hmm.

It took a few permutations to get meld working on windows for me. This is my current .gitconfig:

[merge]
    conflictstyle = diff3
    tool = meld
[mergetool "meld"]
    cmd = \"C:\\Program Files (x86)\\Meld\\Meld.exe\" --auto-merge \"$LOCAL\" \"$BASE\" \"$REMOTE\" --output \"$MERGED\"

Linux:

[merge]
    conflictstyle = diff3
    tool = meld
[mergetool "meld"]
    cmd = meld --auto-merge $LOCAL $BASE $REMOTE --output=$MERGED --diff $BASE $LOCAL --diff $BASE $REMOTE

I believe adding conflictstyle = diff3 changes the inline text to include BASE contents in the output file before meld gets to it, which might give it a head start. Not sure.

Now, since I already noted Meld supports three-way merging, there is another option. When “diff3” git conflict style is set, Meld prints “(??)” on the line showing the content from BASE. source

A few meld command line features I really like:

• --auto-merge does a great job at choosing the right thing for you (it's not bulletproof, but I consider the time saved to be worth any risk).

• You can add extra diff windows in the same command. E.g.:

  --diff $BASE $LOCAL --diff $BASE $REMOTE

  will add two more tabs with the local and incoming patch diffs. These can be quite useful to see separately from the 3 way view to see separate diffs from the base in each branch. I could't get this working on windows though.

• Some version of meld allow you to label tabs with --label. This was more important before git fixed the names of the files passed to meld to include local/base/remote.

• The order of --diff can affect the tab order. I had trouble in some older versions that were putting the additional diffs first, when the main 3 way diff is far more frequently used.

public class MainTwo{
    public static void main(String[] arguments) {
        double[] Average = new double[5];
        Average[0] = 4;
        Average[1] = 5;
        Average[2] = 2;
        Average[3] = 4;
        Average[4] = 5;
        double sum = 0;
        if (Average.length > 0) {
            for (int x = 0; x < Average.length; x++) {
                sum+=Average[x];
                System.out.println(Average[x]);
            }
            System.out.println("Sum is " + sum);
            System.out.println("Average is " + sum/Average.length);
      }
   }
}

There is no direct method to draw a triangle. You can use drawPolygon() method for this. It takes three parameters in the following form: drawPolygon(int x[],int y[], int number_of_points); To draw a triangle: (Specify the x coordinates in array x and y coordinates in array y and number of points which will be equal to the elements of both the arrays.Like in triangle you will have 3 x coordinates and 3 y coordinates which means you have 3 points in total.) Suppose you want to draw the triangle using the following points:(100,50),(70,100),(130,100) Do the following inside public void paint(Graphics g):

int x[]={100,70,130};
int y[]={50,100,100};
g.drawPolygon(x,y,3);

Similarly you can draw any shape using as many points as you want.

On Windows: if you had to mount two directories E:\data\dev & E:\data\dev2

Use:

docker run -v E:\data\dev:c:/downloads -v E:\data\dev2 c:/downloads2 -i --publish 1111:80 -P SomeBuiltContainerName:SomeLabel

Once you used

stmt->execute();

You MAY close it to use another query.

stmt->close();

This problem was hunting me for hours. Hopefully, it will fix yours.

You want to check whether Examples exists in Range("A1").Value If it fails then to check Example right? I think mycode will work perfect. Please check.

Sub test()
Dim string1 As String, string2 As String
string1 = "Examples"
string2 = "Example"
If InStr(1, Range("A1").Value, string1) > 0 Then
    x = 1
ElseIf InStr(1, Range("A1").Value, string2) > 0 Then
    x = 2
End If

End Sub

At the most basic level, something of the form (function(){...})() is a function literal that is executed immediately. What this means is that you have defined a function and you are calling it immediately.

This form is useful for information hiding and encapsulation since anything you define inside that function remains local to that function and inaccessible from the outside world (unless you specifically expose it - usually via a returned object literal).

A variation of this basic form is what you see in jQuery plugins (or in this module pattern in general). Hence:

(function($) {
  ...
})(jQuery);

Which means you're passing in a reference to the actual jQuery object, but it's known as $ within the scope of the function literal.

Type 1 isn't really a plugin. You're simply assigning an object literal to jQuery.fn. Typically you assign a function to jQuery.fn as plugins are usually just functions.

Type 2 is similar to Type 1; you aren't really creating a plugin here. You're simply adding an object literal to jQuery.fn.

Type 3 is a plugin, but it's not the best or easiest way to create one.

To understand more about this, take a look at this similar question and answer. Also, this page goes into some detail about authoring plugins.

This is the solution in Swift 3 that works in iOS 10:

Firstly, you create your own tab bar controller subclass and add it to your tab controller in your storyboard. In the viewDidLoad() method you can then customize the tab bar. It should be stated here that the tintColor attribute of the tabBar represents the color of the selected item not the color of the unselected ones! In order to change the color of the unselected items, I recommend looping through each item and use the original colors of your images, so they are not rendered as grey automatically.

class CustomTabBarVC: UITabBarController
{
    override func viewDidLoad()
    {
        super.viewDidLoad()

        self.tabBar.tintColor = AppColor.normalRed
        self.tabBar.barTintColor = .white
        self.tabBar.isTranslucent = true

        if let items = self.tabBar.items
        {
            for item in items
            {
                if let image = item.image
                {
                    item.image = image.withRenderingMode( .alwaysOriginal )
                }
            }
        }
    }
}

The only downside with this approach is that your item images must already have the desired color you aim for.

Beej's famous network programming guide gives a nice explanation:

In some documentation, you'll see mention of a mystical "PF_INET". This is a weird etherial beast that is rarely seen in nature, but I might as well clarify it a bit here. Once a long time ago, it was thought that maybe a address family (what the "AF" in "AF_INET" stands for) might support several protocols that were referenced by their protocol family (what the "PF" in "PF_INET" stands for).
That didn't happen. Oh well. So the correct thing to do is to use AF_INET in your struct sockaddr_in and PF_INET in your call to socket(). But practically speaking, you can use AF_INET everywhere. And, since that's what W. Richard Stevens does in his book, that's what I'll do here.

Nothing stops you from doing the above, but hold up!

There are some gotchas. Assignment in Javascript is from right to left so when you write:

var moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

it effectively translates to:

var moveUp = (moveDown = (moveLeft = (moveRight = (mouseDown = (touchDown = false)))));

which effectively translates to:

var moveUp = (window.moveDown = (window.moveLeft = (window.moveRight = (window.mouseDown = (window.touchDown = false)))));

Inadvertently, you just created 5 global variables--something I'm pretty sure you didn't want to do.

Note: My above example assumes you are running your code in the browser, hence window. If you were to be in a different environment these variables would attach to whatever the global context happens to be for that environment (i.e., in Node.js, it would attach to global which is the global context for that environment).

Now you could first declare all your variables and then assign them to the same value and you could avoid the problem.

var moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown;
moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

Long story short, both ways would work just fine, but the first way could potentially introduce some pernicious bugs in your code. Don't commit the sin of littering the global namespace with local variables if not absolutely necessary.

Sidenote: As pointed out in the comments (and this is not just in the case of this question), if the copied value in question was not a primitive value but instead an object, you better know about copy by value vs copy by reference. Whenever assigning objects, the reference to the object is copied instead of the actual object. All variables will still point to the same object so any change in one variable will be reflected in the other variables and will cause you a major headache if your intention was to copy the object values and not the reference.

"2.7.0_bf4fda703454".split("_") gives a list of strings:

In [1]: "2.7.0_bf4fda703454".split("_")
Out[1]: ['2.7.0', 'bf4fda703454']

This splits the string at every underscore. If you want it to stop after the first split, use "2.7.0_bf4fda703454".split("_", 1).

If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables:

In [8]: lhs, rhs = "2.7.0_bf4fda703454".split("_", 1)

In [9]: lhs
Out[9]: '2.7.0'

In [10]: rhs
Out[10]: 'bf4fda703454'

An alternative is to use partition(). The usage is similar to the last example, except that it returns three components instead of two. The principal advantage is that this method doesn't fail if the string doesn't contain the separator.

If you don't know how to enable php_mbstring extension in windows, open your php.ini and remove the semicolon before the extension:

change this

;extension=php_mbstring.dll

to this

extension=php_mbstring.dll

after modification, you need to reset your php server.

I added the .resx file via Visual Studio. This created a designer.cs file with properties to immediately return the value of any key I wanted. For example, this is some auto-generated code from the designer file.

/// <summary>
///   Looks up a localized string similar to When creating a Commissioning change request, you must select valid Assignees, a Type, a Component, and at least one (1) affected unit..
/// </summary>
public static string MyErrorMessage {
    get {
        return ResourceManager.GetString("MyErrorMessage", resourceCulture);
    }
}

That way, I was able to simply do:

string message = Errors.MyErrorMessage;

Where Errors is the Errors.resx file created through Visual Studio and MyErrorMessage is the key.

Useful to populate dynamic actions list, and listen to selected action:

var categories = ["Science", "History", "Industry", "Agriculture"]

var handlerSelectedCategory: ((Int) -> ())?

func prepareActions(for title: String, index: Int) -> UIAlertAction {

    let alertAction = UIAlertAction(title: title, style: .default) { (action) in
        self.handlerSelectedCategory?(index)
    }

    return alertAction
}

@objc func presentActions() {

    let optionMenu = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
    // add dymamic options
    for (index, element) in self.categories.enumerated() {
         optionMenu.addAction(prepareActions(for: element, index: index))
    }
    // cancel
    let cancelAction = UIAlertAction(title: "Cancel", style: .destructive)
    optionMenu.addAction(cancelAction)

    handlerSelectedCategory = { index in
        print(index, self.categories[index])
    }

    self.present(optionMenu, animated: true, completion: nil)
}

Okay, I'll bite. You want something like this: If you declare a "property" like this:

Update: I'm now pretty sure that Fredrik Mörk answered your question and gave a solution. I'm not really happy with the idea, but it seems to answer exactly what I understood from your question.

public class PropertyFoo {
  public MyProp<String> Name;
}

this ends up as

public class PropertyFoo {
  public string Name {
    get { /* do predefined stuff here */ }
    set { /*other predefined stuff here */ }
  }
}

No. Not possible and not a property, really. Look for template/snippet support in your IDE.

$query = "SELECT col1,col2,col3 FROM table WHERE id > 100"
$result = mysql_query($query);
if(mysql_num_rows($result)>0)
{
 while($row = mysql_fetch_array()) //here you can use many functions such as mysql_fetch_assoc() and other
 {
//It returns 1 row to your variable that becomes array and automatically go to the next result string
  Echo $row['col1']."|".Echo $row['col2']."|".Echo $row['col2'];
 }
}

You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.

When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.

Reference:
C++03 standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:

• To move the definition to the .h file
• Add explicit instantiations in the .cpp file.
• #include the .cpp file defining the template at the .cpp file using the template.

Each of them have their pros and cons,

Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.

Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.

While including cpp files is confusing at the same time shares the problems of both above approaches.

I find first method the easiest to follow and implement and hence advocte using it.

If you are using Visual Studio, there is a GUI solution as well:

1. From Toolbox add a ContextMenuStrip
2. Select the context menu and add the right click items
3. For each item set the click events to the corresponding functions
4. Select the form / button / image / etc (any item) that the right click menu will be connected
5. Set its ContextMenuStrip property to the menu you have created.

Your code will behave strange if 'TZ' is not set properly, e.g. 'UTC' or 'Asia/Kolkata'

So, you need to do below

>>> import time, os
>>> d='2014-12-11 00:00:00'
>>> p='%Y-%m-%d %H:%M:%S'
>>> epoch = int(time.mktime(time.strptime(d,p)))
>>> epoch
1418236200
>>> os.environ['TZ']='UTC'
>>> epoch = int(time.mktime(time.strptime(d,p)))
>>> epoch
1418256000

As stated in an article by Slicehost:

User setup

So let's start by adding the main user to the Apache user group:

sudo usermod -a -G www-data demo

That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.

You will need to log out and log back in again to enable the group change.

Check the groups now:

groups
...
# demo www-data

So now I am a member of two groups: My own (demo) and the Apache group (www-data).

Folder setup

Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).

Let's set that up:

sudo chgrp -R www-data /home/demo/public_html

As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.

If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.

Setgid

Good so far, but remember the command we just gave only affects existing folders. What about anything new?

We can set the ownership so anything new is also in the 'www-data' group.

The first command will change the permissions for the public_html directory to include the "setgid" bit:

sudo chmod 2750 /home/demo/public_html

That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.

If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:

sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads

The permissions only need to be set once as new files will automatically be assigned the correct ownership.

Like this?

 System.out.println(Name + " " + Income);

Yes, you need $(this) for jQuery functions, but when you want to access basic javascript methods of the element that don't use jQuery, you can just use this.

I just wrote array intersection that correctly handles also duplicates

https://gist.github.com/gkucmierz/8ee04544fa842411f7553ef66ac2fcf0

// array intersection that correctly handles also duplicates_x000D_
_x000D_
const intersection = (a1, a2) => {_x000D_
  const cnt = new Map();_x000D_
  a2.map(el => cnt[el] = el in cnt ? cnt[el] + 1 : 1);_x000D_
  return a1.filter(el => el in cnt && 0 < cnt[el]--);_x000D_
};_x000D_
_x000D_
const l = console.log;_x000D_
l(intersection('1234'.split``, '3456'.split``)); // [ '3', '4' ]_x000D_
l(intersection('12344'.split``, '3456'.split``)); // [ '3', '4' ]_x000D_
l(intersection('1234'.split``, '33456'.split``)); // [ '3', '4' ]_x000D_
l(intersection('12334'.split``, '33456'.split``)); // [ '3', '3', '4' ]

In Python 2.*, by far the fastest approach is the .translate method:

>>> x='aaa12333bb445bb54b5b52'
>>> import string
>>> all=string.maketrans('','')
>>> nodigs=all.translate(all, string.digits)
>>> x.translate(all, nodigs)
'1233344554552'
>>> 

string.maketrans makes a translation table (a string of length 256) which in this case is the same as ''.join(chr(x) for x in range(256)) (just faster to make;-). .translate applies the translation table (which here is irrelevant since all essentially means identity) AND deletes characters present in the second argument -- the key part.

.translate works very differently on Unicode strings (and strings in Python 3 -- I do wish questions specified which major-release of Python is of interest!) -- not quite this simple, not quite this fast, though still quite usable.

Back to 2.*, the performance difference is impressive...:

$ python -mtimeit -s'import string; all=string.maketrans("", ""); nodig=all.translate(all, string.digits); x="aaa12333bb445bb54b5b52"' 'x.translate(all, nodig)'
1000000 loops, best of 3: 1.04 usec per loop
$ python -mtimeit -s'import re;  x="aaa12333bb445bb54b5b52"' 're.sub(r"\D", "", x)'
100000 loops, best of 3: 7.9 usec per loop

Speeding things up by 7-8 times is hardly peanuts, so the translate method is well worth knowing and using. The other popular non-RE approach...:

$ python -mtimeit -s'x="aaa12333bb445bb54b5b52"' '"".join(i for i in x if i.isdigit())'
100000 loops, best of 3: 11.5 usec per loop

is 50% slower than RE, so the .translate approach beats it by over an order of magnitude.

In Python 3, or for Unicode, you need to pass .translate a mapping (with ordinals, not characters directly, as keys) that returns None for what you want to delete. Here's a convenient way to express this for deletion of "everything but" a few characters:

import string

class Del:
  def __init__(self, keep=string.digits):
    self.comp = dict((ord(c),c) for c in keep)
  def __getitem__(self, k):
    return self.comp.get(k)

DD = Del()

x='aaa12333bb445bb54b5b52'
x.translate(DD)

also emits '1233344554552'. However, putting this in xx.py we have...:

$ python3.1 -mtimeit -s'import re;  x="aaa12333bb445bb54b5b52"' 're.sub(r"\D", "", x)'
100000 loops, best of 3: 8.43 usec per loop
$ python3.1 -mtimeit -s'import xx; x="aaa12333bb445bb54b5b52"' 'x.translate(xx.DD)'
10000 loops, best of 3: 24.3 usec per loop

...which shows the performance advantage disappears, for this kind of "deletion" tasks, and becomes a performance decrease.

Here's how I do it

var ts = new TimeSpan(DateTime.UtcNow.Ticks - dt.Ticks);
double delta = Math.Abs(ts.TotalSeconds);

if (delta < 60)
{
  return ts.Seconds == 1 ? "one second ago" : ts.Seconds + " seconds ago";
}
if (delta < 60 * 2)
{
  return "a minute ago";
}
if (delta < 45 * 60)
{
  return ts.Minutes + " minutes ago";
}
if (delta < 90 * 60)
{
  return "an hour ago";
}
if (delta < 24 * 60 * 60)
{
  return ts.Hours + " hours ago";
}
if (delta < 48 * 60 * 60)
{
  return "yesterday";
}
if (delta < 30 * 24 * 60 * 60)
{
  return ts.Days + " days ago";
}
if (delta < 12 * 30 * 24 * 60 * 60)
{
  int months = Convert.ToInt32(Math.Floor((double)ts.Days / 30));
  return months <= 1 ? "one month ago" : months + " months ago";
}
int years = Convert.ToInt32(Math.Floor((double)ts.Days / 365));
return years <= 1 ? "one year ago" : years + " years ago";

Suggestions? Comments? Ways to improve this algorithm?

Another solution is to do this:

static float NextFloat(Random random)
{
    float f;
    do
    {
        byte[] bytes = new byte[4];
        random.NextBytes(bytes);
        f = BitConverter.ToSingle(bytes, 0);
    }
    while (float.IsInfinity(f) || float.IsNaN(f));
    return f;
}

You usually use padding to add distance between a border and a content.However, background are spread on padding.

You can still do it with nested element.

html :

<div id="outter">
    <div id="inner">
        test
    </div>
</div>

outter div :

border-style: ridge;
border-color: #567498;
border-spacing:10px;
min-width: 100px;
min-height: 100px;
float:left;

inner div :

width: 100px;
min-height: 100px;
margin: 10px;
background-image: -webkit-gradient(
    linear,
    left bottom,
    left top,
    color-stop(0, rgb(39,54,73)),
    color-stop(1, rgb(30,42,54))
);
background-image: -moz-linear-gradient(
    center bottom,
    rgb(39,54,73) 0%,
    rgb(30,42,54) 100%
        );}

Based on @carlosfigueira 's answer, I looked further into WebClient's methods and found UploadValues, which is exactly what I want:

Using client As New Net.WebClient
    Dim reqparm As New Specialized.NameValueCollection
    reqparm.Add("param1", "somevalue")
    reqparm.Add("param2", "othervalue")
    Dim responsebytes = client.UploadValues(someurl, "POST", reqparm)
    Dim responsebody = (New Text.UTF8Encoding).GetString(responsebytes)
End Using

The key part is this:

client.UploadValues(someurl, "POST", reqparm)

It sends whatever verb I type in, and it also helps me create a properly url encoded form data, I just have to supply the parameters as a namevaluecollection.

I would say the best reference is Format for Literal IPv6 Addresses in URL's where usage of [] is defined.

Also, if it is for programming and code, specifically Java, I would suggest this readsClass for Inet6Address java/net/URL definition where usage of Inet4 address in Inet6 connotation and other cases are presented in details. For my case, IPv4-mapped address Of the form::ffff:w.x.y.z, for IPv6 address is used to represent an IPv4 address also solved my problem. It allows the native program to use the same address data structure and also the same socket when communicating with both IPv4 and IPv6 nodes. This is the case on Amazon cloud Linux boxes default setup.

An update:

As of Laravel 5.3 doing this in a single step is possible; the firstOrCreate method now accepts an optional second array as an argument.

The first array argument is the array on which the fields/values are matched, and the second array is the additional fields to use in the creation of the model if no match is found via matching the fields/values in the first array:

Visiblity property has not been implemented on the Tabpages, and there is no Insert method also.

You need to manually insert and remove tab pages.

Here is a work around for the same.

For Intellij IDEA Community 2019.1 you will need to follow these steps :

File -> New -> Edit File Templates.. -> Class -> /* Created by ${USER} on ${DATE} */

You can also do:

obj = ClassModel.get_by_id(object_id)

This works, but there may I'm not sure if it's supported in Django 2.

Here is a working and simple solution for checking existence of a function and triaging that function dynamically by another function;

Trigger function

function runDynmicFunction(functionname){ 

    if (typeof window[functionname] == "function"  ) { //check availability

        window[functionname]("this is from the function it "); //run function and pass a parameter to it
    }
}

and you can now generate the function dynamically maybe using php like this

function runThis_func(my_Parameter){

    alert(my_Parameter +" triggerd");
}

now you can call the function using dynamically generated event

<?php

$name_frm_somware ="runThis_func";

echo "<input type='button' value='Button' onclick='runDynmicFunction(\"".$name_frm_somware."\");'>";

?>

the exact HTML code you need is

<input type="button" value="Button" onclick="runDynmicFunction('runThis_func');">

While this is not a GUI tool, my quick tests indicated that diffxml has some promise. The author appears to have thought about the complexities of representing diffs for nested elements in a standardized way (his DUL - Delta Update Language specification).

Installing and running his tools, I can say that the raw text output is quite clear and concise. It doesn't offer the same degree of immediate apprehension as a GUI tool, but given that the output is standardized as DUL, perhaps you would be able to take that and build a tool to generate a visual representation. I'd certainly love to see one.

The author's "links" section does reference a few other XML differencing tools, but as you mentioned in your post, they're all proprietary.

Here are my solutions with word boundary.

let s = "At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga. Et harum quidem rerum facilis est et expedita distinctio. Nam libero tempore, cum soluta nobis est eligendi optio cumque nihil impedit quo minus id quod maxime placeat facere possimus, omnis voluptas assumenda est, omnis dolor repellendus. Temporibus autem quibusdam et aut officiis debitis aut rerum necessitatibus saepe eveniet ut et voluptates repudiandae sint et molestiae non recusandae.

let s_split = s.split(/\s+/);
let word_count = 0;
let result = "";
//1
for(let i = 0; word_count < 100; i++){
  word_count += s_split[i].length+1;
  result += (s_split[i] + " ");
}
console.log(result);
// 2
word_count = 0;
result = s_split.reduce((x,y)=>{
  word_count+=(y.length+1);
  if(word_count>=100) return x;
  else return x+" "+y;}, "").substring(1);

Google maintains a server infrastructure that grows dynamically with the ever increasing internet demands. This link by google describes the method to remain up to date with their IP address ranges.

When you need the literal IP addresses for Google Apps mail servers, start by using one of the common DNS lookup commands (nslookup, dig, host) to retrieve the SPF records for the domain _spf.google.com, like so:

nslookup -q=TXT _spf.google.com 8.8.8.8

This returns a list of the domains included in Google's SPF record, such as: _netblocks.google.com, _netblocks2.google.com, _netblocks3.google.com

Now look up the DNS records associated with those domains, one at a time, like so:

nslookup -q=TXT _netblocks.google.com 8.8.8.8
nslookup -q=TXT _netblocks2.google.com 8.8.8.8
nslookup -q=TXT _netblocks3.google.com 8.8.8.8

The results of these commands contain the current range of addresses.

Use -1 index (negative indices count backward from the end of the array):

a[-1] # => 5
b[-1] # => 6

or Array#last method:

a.last # => 5
b.last # => 6

In my case that URL is not working in browser also.

I check with https://www.google.com/

webView.loadUrl("https://www.google.com/")

And it worked for me.

And here's how to do it in Swift:

 func registerForKeyboardNotifications() {
    NSNotificationCenter.defaultCenter().addObserver(
        self,
        selector: "keyboardWasShown:",
        name: UIKeyboardDidShowNotification,
        object: nil)

    NSNotificationCenter.defaultCenter().addObserver(
        self,
        selector: "keyboardWillBeHidden:",
        name: UIKeyboardWillHideNotification,
        object: nil)
}

func keyboardWasShown(notification: NSNotification) {
    println("Keyboard was shown");
}

func keyboardWillBeHidden(notification: NSNotification) {
    println("Keyboard was dismissed");
}

Don't forget to unregister:

 override func viewWillDisappear(animated: Bool) {
    NSNotificationCenter.defaultCenter().removeObserver(self,
        name: UIKeyboardDidShowNotification,
        object: nil)

    NSNotificationCenter.defaultCenter().removeObserver(self,
        name: UIKeyboardWillHideNotification,
        object: nil)
}

And if you want to dismiss keyboard on pressing the "Return" button:

class ViewController: UIViewController, UITextFieldDelegate {

@IBOutlet weak var yourTextField: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()
    registerForKeyboardNotifications()
    yourTextField.delegate = self
}

func textFieldShouldReturn(textField: UITextField!) -> Bool {
    self.view.endEditing(true);
    return false;
}

}

Going further with the rev-list option, if you want to find the most recent merge commit from your master branch into your production branch (as a purely hypothetical example):

git checkout `git rev-list -n 1 --merges --first-parent --before="2012-01-01" production`

I needed to find the code that was on the production servers as of a given date. This found it for me.

Read : 101 LINQ Samples in that LINQ - Grouping Operators from Microsoft MSDN site

var x = from t in types  group t by t.Type
         into grp    
         select new { type = grp.key, count = grp.Count() };

forsingle object make use of stringbuilder and append it that will do or convert this in form of dictionary

    // fordictionary 
  var x = (from t in types  group t by t.Type
     into grp    
     select new { type = grp.key, count = grp.Count() })
   .ToDictionary( t => t.type, t => t.count);

  var x = from t in types  group t by t.Type
         into grp    
         select new { type = grp.key, count = grp.Count() };

  {
       //: is separator between to object
       MyStringBuilder.Append(result.Type +" , "+ result.Count + " : ");
  }
  Console.WriteLine(MyStringBuilder.ToString());   

You can simply use $_GET especially if you know the othervar's name. If you want to be on the safe side, use if (isset ($_GET ['varname'])) to test for existence.

Supposing you use sql server:

WHERE StartTime BETWEEN DATEADD(HOUR, -1, GetDate())
                    AND DATEADD(HOUR, 1, GetDate())

use desc tablename from Hive CLI or beeline to get all the column names. If you want the column names in a file then run the below command from the shell.

$ hive -e 'desc dbname.tablename;' > ~/columnnames.txt

where dbname is the name of the Hive database where your table is residing You can find the file columnnames.txt in your root directory.

$cd ~
$ls

curl doesn't have an option to that (without also specifying the filename), but wget does. The directory can be relative or absolute. Also, the directory will automatically be created if it doesn't exist.

wget -P relative/dir "$url"

wget -P /absolute/dir "$url"

Use a combination of Array.prototype.filter and Array.prototype.includes:

const filteredArray = array1.filter(value => array2.includes(value));

For older browsers, with Array.prototype.indexOf and without an arrow function:

var filteredArray = array1.filter(function(n) {
    return array2.indexOf(n) !== -1;
});

NB! Both .includes and .indexOf internally compares elements in the array by using ===, so if the array contains objects it will only compare object references (not their content). If you want to specify your own comparison logic, use .some instead.

I had similar issue, trying to load data from Excel spreadsheet; and was running on WinX64. So I went VS BI`s project properties: Configuration Properties \ Dbugging and Switch Run64BitRuntime from True to False. It worked.

I ran into this issue with Python 3.6 and Python 3.7. The top answer (running pip install --upgrade pip enum34) did not solve the problem.

I don't know why, but the reason why this error happen is because enum.py was missing from .venv/myvenv/lib/python3.7/.

But the file was in /usr/lib/python3.7/.

Following this answer, I just created the symbolic link by myself :

ln -s /usr/lib/python3.7/enum.py .venv/myvenv/lib/python3.7/enum.py

Another approach for same issue may help you Read and write file in private context of application

                 String NOTE = "note.txt";  
                 private void writeToFile() {
        try {
         OutputStreamWriter out = new OutputStreamWriter(openFileOutput(
                NOTES, 0));

         out.write("testing");
         out.close();
         }

        catch (Throwable t) {
        Toast.makeText(this, "Exception: " + t.toString(), 2000).show();

To get all values of all sections from appsettings.json

        public static string[] Sections = { "LogDirectory", "Application", "Email" };
        Dictionary<string, string> sectionDictionary = new Dictionary<string, string>();

        List<string> sectionNames = new List<string>(Sections);
        
        sectionNames.ForEach(section =>
        {
            List<KeyValuePair<string, string>> sectionValues = configuration.GetSection(section)
                    .AsEnumerable()
                    .Where(p => p.Value != null)
                    .ToList();
            foreach (var subSection in sectionValues)
            {
                sectionDictionary.Add(subSection.Key, subSection.Value);
            }
        });
        return sectionDictionary;

The reason for this error is because there is a mismatch of the ABI between your app and the native library you linked against. Another words, your app and your .so is targeting different ABI.

if you create your app using latest Android Studio templates, its probably targeting the arm64-v8a but your .so may be targeting armeabi-v7a for example.

There is 2 way to solve this problem:

1. build your native libraries for each ABI your app support.
2. change your app to target older ABI that your .so built against.

Choice 2 is dirty but I think you probably have more interested in:

change your app's build.gradle

android {
    defaultConfig {
        ...
        ndk {
            abiFilters 'armeabi-v7a'
        }
   }
}

There are two problems. As in the question, select-string needs to operate on the output string, which can be had from "out-string". Also, select-string doesn't operate linewise on strings that are piped to it. Here is a generic solution

(alias|out-string) -split "`n" | select-string Write 

curl sends POST requests with the default content type of application/x-www-form-urlencoded. If you want to send a JSON request, you will have to specify the correct content type header:

$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"

But that will only work if the server accepts json input. The .json at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.

The reason you get a 401 and not some other error is probably because the server can't extract the auth_token from your request.

Now you can!

7 years later update: This is terrible advice. Please don't do this.

If you just need to pass variables from PHP to the javascript, you can have a tag in the php/html file using the javascript to begin with.

<script type="text/javascript">
    phpVars = new Array();
    <?php foreach($vars as $var) {
        echo 'phpVars.push("' . $var . '");';
    };
    ?>
</script>
<script type="text/javascript" src="yourScriptThatUsesPHPVars.js"></script>

If you're trying to call functions, then you can do this like this

<script type="text/javascript" src="YourFunctions.js"></script>
<script type="text/javascript">
    functionOne(<?php echo implode(', ', $arrayWithVars); ?>);
    functionTwo(<?php echo $moreVars; ?>, <?php echo $evenMoreVars; ?>);
</script>

You can use:

<input (input)="saverange()>

Here is another simple answer

gsub("^.*:","", string)

It's very simple.

1. You add an image.

2. You create a css property to this image.

   img { transition: all 0.3s ease-in-out 0s; }
   

3. You add an animation like that:

   img:hover
   {
       cursor: default;
       transform: rotate(360deg);
       transition: all 0.3s ease-in-out 0s;
   }
   

In a project I did recently, I solved this problem with jQuery's delegated events feature. It looks for certain elements using a jQuery selector, and adds/removes a CSS class to those elements when the mouse is over the element. It seems to work well as far as I've been able to test it, which includes IE10 on a touch-capable notebook running Windows 8.

$(document).ready(
    function()
    {
        // insert your own selector here: maybe '.hoverable'?
        var selector = 'button, .hotspot';

        $('body')
            .on('mouseover', selector, function(){ $(this).addClass('mouseover');    })
            .on('mouseout',  selector, function(){ $(this).removeClass('mouseover'); })
            .on('click',     selector, function(){ $(this).removeClass('mouseover'); });
    }
);

edit: this solution does, of course, require that you alter your CSS to remove the ":hover" selectors, and contemplate in advance on which elements you want to be "hoverable".

If you have very many elements on your page (like several thousand) it may get a bit slow, though, because this solution catches events of three types on all elements in the page, and then does its thing if the selector matches. I named the CSS class "mouseover" instead of "hover", because I didn't want any CSS readers to read ":hover" where I wrote ".hover".

To add a foreign key (grade_id) to an existing table (users), follow the following steps:

ALTER TABLE users ADD grade_id SMALLINT UNSIGNED NOT NULL DEFAULT 0;
ALTER TABLE users ADD CONSTRAINT fk_grade_id FOREIGN KEY (grade_id) REFERENCES grades(id);

If you are just interested in the use of Access-Control-Allow-Origin:*

You can do that with this .htaccess file at the site root.

Header set Access-Control-Allow-Origin "*"

Request Dispatcher is an Interface which is used to dispatch the request or response from web resource to the another web resource. It contains mainly two methods.

1. request.forward(req,res): This method is used forward the request from one web resource to another resource. i.e from one servlet to another servlet or from one web application to another web appliacation.

2. response.include(req,res): This method is used include the response of one servlet to another servlet

NOTE: BY using Request Dispatcher we can forward or include the request or responses with in the same server.

request.sendRedirect(): BY using this we can forward or include the request or responses across the different servers. In this the client gets a intimation while redirecting the page but in the above process the client will not get intimation

If you just want to know about your screen width, you can just search for "smallest screen width" in your developer options. You can even edit it.

substring(int startIndex, int endIndex)

If you don't specify endIndex, the method will return all the characters from startIndex.

startIndex : starting index is inclusive

endIndex : ending index is exclusive

Example:

String str = "abcdefgh"

str.substring(0, 4) => abcd

str.substring(4, 6) => ef

str.substring(6) => gh

I done this, seems to work fine

if grep $SearchTerm $FileToSearch; then
   echo "$SearchTerm found OK"
else
   echo "$SearchTerm not found"

The jQuery.browser options was deprecated earlier and removed in 1.9 release along with a lot of other deprecated items like .live.

For projects and external libraries which want to upgrade to 1.9 but still want to support these features jQuery have release a migration plugin for the time being.

If you need backward compatibility you can use migration plugin.

A much easier way is to go to Data and select Group or Subtotal. Instant collapsible rows without messing with pivot tables or VBA.

When attempting to export data using the accepted answer I got an error:

ERROR 1235 (42000) at line 3367: This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table'

As mentioned above:

mysqldump --no-create-info

Will export the data but it will also export the create trigger statements. If like me your outputting database structure (which also includes triggers) with one command and then using the above command to get the data you should also use '--skip-triggers'.

So if you want JUST the data:

mysqldump --no-create-info --skip-triggers

will I get the same results?

Not really. I don't know of a workaround for PHP 5.2, though.

What is the difference between new self and new static?

self refers to the same class in which the new keyword is actually written.

static, in PHP 5.3's late static bindings, refers to whatever class in the hierarchy you called the method on.

In the following example, B inherits both methods from A. The self invocation is bound to A because it's defined in A's implementation of the first method, whereas static is bound to the called class (also see get_called_class()).

class A {
    public static function get_self() {
        return new self();
    }

    public static function get_static() {
        return new static();
    }
}

class B extends A {}

echo get_class(B::get_self());  // A
echo get_class(B::get_static()); // B
echo get_class(A::get_self()); // A
echo get_class(A::get_static()); // A

I use AquaFold at work on Windows, but it's based on Java and supports Mac OS X.

I would use a change event not a click like this:

$('input[name="name-of-radio-group"]').change( function() {
  alert($(this).val())
})

This is what I used for similar type of use case as yours.

<style type="text/css">
#element1 {display:inline-block; width:45%; padding:10px}
#element2 {display:inline-block; width:45%; padding:10px}
</style>

<div id="element1">
 element 1 markup
</div>
<div id="element2">
 element 2 markup
</div>

Adjust your width and padding as per your requirement. Note - Do not exceed 'width' more than 100% altogether (ele1_width+ ele2_width) to add 'padding', keep it less than 100%.

@zende's answer was the only one that covered columns with a mix of ascii and non ascii characters, but it also had that problematic hex thing. I used this:

SELECT * FROM `table` WHERE NOT `column` REGEXP '^[ -~]+$' AND `column` !=''

The following is works best in my opinion:

Get-Item Env:PATH

1. It's shorter and therefore a little bit easier to remember than Get-ChildItem. There's no hierarchy with environment variables.
2. The command is symmetrical to one of the ways that's used for setting environment variables with Powershell. (EX: Set-Item -Path env:SomeVariable -Value "Some Value")
3. If you get in the habit of doing it this way you'll remember how to list all Environment variables; simply omit the entry portion. (EX: Get-Item Env:)

I found the syntax odd at first, but things started making more sense after I understood the notion of Providers. Essentially PowerShell let's you navigate disparate components of the system in a way that's analogous to a file system.

What's the point of the trailing colon in Env:? Try listing all of the "drives" available through Providers like this:

PS> Get-PSDrive

I only see a few results... (Alias, C, Cert, D, Env, Function, HKCU, HKLM, Variable, WSMan). It becomes obvious that Env is simply another "drive" and the colon is a familiar syntax to anyone who's worked in Windows.

You can navigate the drives and pick out specific values:

Get-ChildItem C:\Windows
Get-Item C:
Get-Item Env:
Get-Item HKLM:
Get-ChildItem HKLM:SYSTEM

You can add the ProgressBar to listview footer:

private ListView listview;
private ProgressBar progressBar;

...

progressBar = (ProgressBar) LayoutInflater.from(this).inflate(R.layout.progress_bar, null);

listview.addFooterView(progressBar);

layout/progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/load_progress"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:indeterminate="true"
     />

when the data is loaded to the adapter view call:

        listview.removeFooterView(progressBar);

I thought you could deploy just your .aspx page without the .aspx.cs so long as the DLL was in your bin. Part of the issue here is how visual studio .net works with .aspx pages.

I know for sure that VS2008 with asp.net MVC RC you don't have code-behind files for your views.

I realized that not using in memory processing, when you have a huge amount of data, is faster than "piping" the commands. So I saved the result to a file and analyzed it afterwards:

ls -1 /path/to/dir > count.txt && cat count.txt | wc -l

Install Inkscape and call it as command line:

${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -j -e ${dest_png}

You can also snap specific rectangular area only using parameter -j, e.g. co-ordinate "0:125:451:217"

${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -j -a ${coordinates} -e ${dest_png}

If you want to show only one object in the SVG file, you can specify the parameter -i with the object id that you have setup in the SVG. It hides everything else.

${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -i ${object} -j -a ${coordinates} -e ${dest_png}

I believe prestomanifesto was on the right track. It depends on what kind of element it is. You would need to use element.get_attribute('value') for input elements and element.text to return the text node of an element.

You could check the WebElement object with element.tag_name to find out what kind of element it is and return the appropriate value.

This should help you figure out:

driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')

element_text = element.text
element_attribute_value = element.get_attribute('value')

print element
print 'element.text: {0}'.format(element_text)
print 'element.get_attribute(\'value\'): {0}'.format(element_attribute_value)
driver.quit()

Tools: Testers and Explainers

(This section contains non-Stack Overflow links.)

The .btn-lg class has the following CSS in Bootstrap 3 (link):

.btn-lg {
  padding: 10px 16px;
  font-size: 18px;
  line-height: 1.33;
  border-radius: 6px;
}

If you apply the same font-size and line-height to your span (either .glyphicon-link or a newly created .glyphicons-lg if you're going to use this effect in more than one instance), you'll get a Glyphicon the same size as the large button.

This will do what you are looking for in C# (WebDriver/Selenium 2.0)

var browser = new FirefoxDriver();
var overallTimeout = Timespan.FromSeconds(10);
var sleepCycle = TimeSpan.FromMiliseconds(50);
var wait = new WebDriverWait(new SystemClock(), browser, overallTimeout, sleepCycle);
var hasTimedOut = wait.Until(_ => /* here goes code that looks for the map */);

And never use Thread.Sleep because it makes your tests unreliable

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

Your find should look like that to avoid sending directory names to sed:

find ./ -type f -exec sed -i -e 's/apple/orange/g' {} \;

Just note to anyone trying the REGEXP to use "LIKE IN" functionality.

IN allows you to do:

field IN (
'val1',
'val2',
'val3'
)

In REGEXP this won't work

REGEXP '
val1$|
val2$|
val3$
'

It has to be in one line like this:

REGEXP 'val1$|val2$|val3$'
