std::pair<int, int> divide(int dividend, int divisor)
{
   // :
   return std::make_pair(quotient, remainder);
}

std::pair<int, int> answer = divide(5,2);
 // answer.first == quotient
 // answer.second == remainder

std::pair is essentially your struct solution, but already defined for you, and ready to adapt to any two data types.

How about this?

for (let [key, value] of Object.entries(obj)) {
    ...
}

Drop the parentheses and commas:

 myBackupFunction ".." "..." "xx"

And the function should look like this:

function myBackupFunction() {
    # Here $1 is the first parameter, $2 the second, etc.
}

m59's answer is pretty good. The one thing I don't like about it is that it uses divs for what could potentially be data for a table.

So in conjunction with m59's filter (answer somewhere above), here is how to display it in a table.

<table>
    <tr class="" ng-repeat="rows in foos | chunk:2">
        <td ng-repeat="item in rows">{{item}}</td>
    </tr>
</table>

How about:

string s = orig.Replace("\n","").Replace("\r","");

which should handle the common line-endings.

Alternatively, if you have that string hard-coded or are assembling it at runtime - just don't add the newlines in the first place.

This topic provides basic information about deploying and configuring a registry

Run a local registry

Before you can deploy a registry, you need to install Docker on the host.

Use a command like the following to start the registry container:

start_registry.sh

#!/bin/bash

docker run -d \
  -p 5000:5000 \
  --restart=always \
  --name registry \
  -v /data/registry:/var/lib/registry \
  registry:2

Copy an image from Docker Hub to your registry

1. Pull the ubuntu:16.04 image from Docker Hub.

   $ docker pull ubuntu:16.04
   

2. Tag the image as localhost:5000/my-ubuntu. This creates an additional tag for the existing image. When the first part of the tag is a hostname and port, Docker interprets this as the location of a registry, when pushing.

   $ docker tag ubuntu:16.04 localhost:5000/my-ubuntu
   

3. Push the image to the local registry running at localhost:5000:

   $ docker push localhost:5000/my-ubuntu
   

4. Remove the locally-cached images. This does not remove the localhost:5000/my-ubuntu image from your registry.

   $ docker image remove ubuntu:16.04
   $ docker image remove localhost:5000/my-ubuntu
   

5. Pull the localhost:5000/my-ubuntu image from your local registry.

   $ docker pull localhost:5000/my-ubuntu
   

According to docs.docker.com, this is very insecure and is not recommended.

1. Edit the daemon.json file, whose default location is /etc/docker/daemon.json on Linux or C:\ProgramData\docker\config\daemon.json on Windows Server. If you use Docker for Mac or Docker for Windows, click Docker icon -> Preferences -> Daemon, add in the insecure registry.

   If the daemon.json file does not exist, create it. Assuming there are no other settings in the file, it should have the following contents:

   {
     "insecure-registries" : ["myregistrydomain.com:5000"]
   }
   

   With insecure registries enabled, Docker goes through the following steps:

   • First, try using HTTPS.
     • If HTTPS is available but the certificate is invalid, ignore the error about the certificate.
     • If HTTPS is not available, fall back to HTTP.

2. Restart Docker for the changes to take effect.

I would stack generator expressions:

with open(filename) as f_in:
    lines = (line.rstrip() for line in f_in) # All lines including the blank ones
    lines = (line for line in lines if line) # Non-blank lines

Now, lines is all of the non-blank lines. This will save you from having to call strip on the line twice. If you want a list of lines, then you can just do:

with open(filename) as f_in:
    lines = (line.rstrip() for line in f_in) 
    lines = list(line for line in lines if line) # Non-blank lines in a list

You can also do it in a one-liner (exluding with statement) but it's no more efficient and harder to read:

with open(filename) as f_in:
    lines = list(line for line in (l.strip() for l in f_in) if line)

Update:

I agree that this is ugly because of the repetition of tokens. You could just write a generator if you prefer:

def nonblank_lines(f):
    for l in f:
        line = l.rstrip()
        if line:
            yield line

Then call it like:

with open(filename) as f_in:
    for line in nonblank_lines(f_in):
        # Stuff

update 2:

with open(filename) as f_in:
    lines = filter(None, (line.rstrip() for line in f_in))

and on CPython (with deterministic reference counting)

lines = filter(None, (line.rstrip() for line in open(filename)))

In Python 2 use itertools.ifilter if you want a generator and in Python 3, just pass the whole thing to list if you want a list.

inside the Form, You can use this code. Replace your variable name (i use $variable)

<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">

Many times you want to identify the row that has that column with the longest length, especially if you are troubleshooting to find out why the length of a column on a row in a table is so much longer than any other row, for instance. This query will give you the option to list an identifier on the row in order to identify which row it is.

select ID, [description], len([description]) as descriptionlength
FROM [database1].[dbo].[table1]
where len([description]) = 
 (select max(len([description]))
  FROM [database1].[dbo].[table1]

If you have a valid dtd file for the xml then you can easily transform json to xml and xml to json using the eclipselink jar binary.

Refer this: http://www.cubicrace.com/2015/06/How-to-convert-XML-to-JSON-format.html

The article also has a sample project (including the supporting third party jars) as a zip file which can be downloaded for reference purpose.

like this: put intro outside your document ready, Good discussion here: http://forum.jquery.com/topic/how-do-i-declare-a-global-variable-in-jquery @thecodeparadox is awesomely fast :P anyways!

 var intro;

$(document).ready(function() {



    if ($('.intro_check').is(':checked')) {
        intro = true;
        $('.intro').wrap('<div class="disabled"></div>');
    };

    $('.intro_check').change(function(){
        if(this.checked) {
            intro = false;
            $('.enabled').removeClass('enabled').addClass('disabled');
        } else {
            intro = true;
            if($('.intro').exists()) {
                $('.disabled').removeClass('disabled').addClass('enabled'); 
            } else {
                $('.intro').wrap('<div class="disabled"></div>');
            }
        }
    });
});

Java 7 one line solution

List<String> lines = Files.readAllLines(Paths.get("file"), StandardCharsets.UTF_8);

or

 String text = new String(Files.readAllBytes(Paths.get("file")), StandardCharsets.UTF_8);

This will work everywhere.

<body>
  <table style="table-layout:fixed;">
  <tr>
    <td><div style="word-wrap: break-word; width: 100px" > gdfggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg</div></td>
  </tr>
  </table>
 </body>

All the above answers might work. But Below is what worked for me. I had multiple vagrant host: host1, host2. I wanted to copy file from ~/Desktop/file.sh to host: host1 I did:

    $vagrant upload ~/Desktop/file.sh host1

This will copy ~/Desktop/file.sh under /home/xxxx where xxx is your vagrant user under host1

Try using this code:

var datetime = 1383066000000; // anything
var date = new Date(datetime);
var options = {
        year: 'numeric', month: 'numeric', day: 'numeric',
    };

var result = date.toLocaleDateString('en', options); // 10/29/2013

As of July 2016, the Download ZIP button has moved under Clone or download to extreme-right of header under the Code tab:

If you don't see the button:

• Make sure you've selected <> Code tab from right side navigation menu, or

• Repo may not have a zip prepared. Add /archive/master.zip to the end of the repository URL and to generate a zipfile of the master branch.

  http://github.com/user/repository/

-to-

http://github.com/user/repository/archive/master.zip

to get the master branch source code in a zip file. You can do the same with tags and branch names, by replacing master in the URL above with the name of the branch or tag.

Same as John's answer, but a slightly less verbose extension method.

public static string GetDirectoryPath(this Assembly assembly)
{
    string filePath = new Uri(assembly.CodeBase).LocalPath;
    return Path.GetDirectoryName(filePath);            
}

Now you can do:

var localDir = Assembly.GetExecutingAssembly().GetDirectoryPath();

or if you prefer:

var localDir = typeof(DaoTests).Assembly.GetDirectoryPath();

You will to have to set header content type in your php like this:

 <?php

 header('Content-type:application/json');

 ?>

Watch these Video for better understanding....

Reference: http://www.youtube.com/watch?v=EvFXWqEqh6o

Java's parser in java.net.URI is going to fail if the URI isn't fully encoded to its standards. For example, try to parse: http://www.google.com/search?q=cat|dog. An exception will be thrown for the vertical bar.

urllib makes it easy to convert a string to a java.net.URI. It will pre-process and escape the URL.

assertEquals("http://www.google.com/search?q=cat%7Cdog",
    Urls.createURI("http://www.google.com/search?q=cat|dog").toString());

If your parameter happens to be a complex object, this solves the problem. The key is the RouteValueDictionary constructor.

return RedirectToAction("Action", new RouteValueDictionary(Model))

If you happen to have collections, it makes it a bit trickier, but this other answer covers this very nicely.

Well, a for or while loop differs from a do while loop. A do while executes the statements atleast once, even if the condition turns out to be false.

The for loop you specified is absolutely correct.

Although i will do all the loops for you once again.

int sum = 0;
// for loop

for (int i = 1; i<= 100; i++){
    sum = sum + i;
}
System.out.println(sum);

// while loop

sum = 0;
int j = 1;

while(j<=100){
    sum = sum + j;
    j++;
}

System.out.println(sum);

// do while loop

sum = 0;
j = 1;

do{
    sum = sum + j;
    j++;
}
while(j<=100);

System.out.println(sum);

In the last case condition j <= 100 is because, even if the condition of do while turns false, it will still execute once but that doesn't matter in this case as the condition turns true, so it continues to loop just like any other loop statement.

If someone is looking for an alternative for old java versions, you can try this one I wrote:

/**
 * Strong typed Lambda to return NULL or DEFAULT VALUES instead of runtime errors. 
 * if you override the defaultValue method, if the execution result was null it will be used in place
 * 
 * 
 * Sample:
 * 
 * It won't throw a NullPointerException but null.
 * <pre>
 * {@code
 *  new RuntimeExceptionHandlerLambda<String> () {
 *      @Override
 *      public String evaluate() {
 *          String x = null;
 *          return x.trim();
 *      }  
 *  }.get();
 * }
 * <pre>
 * 
 * 
 * @author Robson_Farias
 *
 */

public abstract class RuntimeExceptionHandlerLambda<T> {

    private T result;

    private RuntimeException exception;

    public abstract T evaluate();

    public RuntimeException getException() {
        return exception;
    }

    public boolean hasException() {
        return exception != null;
    }

    public T defaultValue() {
        return result;
    }

    public T get() {
        try {
            result = evaluate();
        } catch (RuntimeException runtimeException) {
            exception = runtimeException;
        }
        return result == null ? defaultValue() : result;
    }

}

A more direct way would be:

myvar=$(mysql mydatabase -u $user -p$password -se "SELECT a, b, c FROM table_a")

You just have to parse the string using JSON.parse like this :

var json_result = {"AuthenticateUserResult":"{\"PKPersonId\":1234,\"Salutation\":null,\"FirstName\":\"Miqdad\",\"LastName\":\"Kumar\",\"Designation\":null,\"Profile\":\"\",\"PhotoPath\":\"\/UploadFiles\/\"}"};

var parsed = JSON.parse(json_result.AuthenticateUserResult);
console.log(parsed);

Here you will have something like this :

Designation
null

FirstName
"Miqdad"

LastName
"Kumar"

PKPersonId
1234

PhotoPath
"/UploadFiles/"

Profile
""

Salutation
null

And for the request, don't forget to set dataType:'jsonp' and to add a file in the root directory of your site called crossdomain.xml and containing :

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<!-- Read this: www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html -->

<!-- Most restrictive policy: -->
<site-control permitted-cross-domain-policies="none"/>

<!-- Least restrictive policy: -->
<!--
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" secure="false"/>
<allow-http-request-headers-from domain="*" headers="*" secure="false"/>
-->
</cross-domain-policy>

EDIT to take care of Sanjay Kumar POST

So you can set the callback function to be called in the JSONP using jsonpCallback!

$.Ajax({
    jsonpCallback : 'your_function_name',
    //OR with anonymous function
    jsonpCallback : function(data) {
        //do stuff
    },
    ...
});

The reason I used a + instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.

word[Aa]\s+word[Bb]\s+word[Cc]

will match:

wordA wordB     wordC
worda wordb wordc
wordA   wordb   wordC

The words, in this expression, will have to be specific, and also in order (a, b, then c)

JavaScript is a dynamic language. You could just add it to the object itself.

var marker = new google.maps.Marker(markerOptions);
marker.metadata = {type: "point", id: 1};

Also, because all v3 objects extend MVCObject(). You can use:

marker.setValues({type: "point", id: 1});
// or
marker.set("type", "point");
marker.set("id", 1);
var val = marker.get("id");

If you look at this bug 224128, it appears that MergeSort is being used by Mozilla.

Under some circumstances (if you get "ERROR 1064 (42000): You have an error in your SQL syntax;...") you need to do

ALTER TABLE mytable MODIFY mytable.mycolumn varchar(255);

You could just do ...

(.*?)\.txt

tested here..

The Original poster didn't mean to write:

  char* str = "blablabla";

but

  char str[128] = "blablabla";

Now, adding a single character would seem more efficient than adding a whole string with strcat. Going the strcat way, you could:

  char tmpstr[2];
  tmpstr[0] = c;
  tmpstr[1] = 0;
  strcat (str, tmpstr);

but you can also easily write your own function (as several have done before me):

  void strcat_c (char *str, char c)
  {
    for (;*str;str++); // note the terminating semicolon here. 
    *str++ = c; 
    *str++ = 0;
  }

In sake of readability it should be something like

<?php 
  $countries = $myaddress->get_countries();
  foreach($countries as $value) {
    $selected ='';
    if($value=='United States') $selected ='selected="selected"'; 
    echo '<option value="'.$value.'"'.$selected.'>'.$value.'</option>';
  }
?>

desire to stuff EVERYTHING in a single line is a decease, man. Write distinctly.

But there is another way, a better one. There is no need to use echo at all. Learn to use templates. Prepare your data first, and display it only then ready.

Business logic part:

$countries = $myaddress->get_countries();
$selected_country = 1;    

Template part:

<? foreach($countries as $row): ?>
<option value="<?=$row['id']?>"<? if ($row['id']==$current_country):> "selected"><? endif ?>
  <?=$row['name']?>
</option>
<? endforeach ?>

I always use something like the following:

public static String GetTimestamp(this DateTime value)
{
    return value.ToString("yyyyMMddHHmmssfff");
}

This will give you a string like 200905211035131468, as the string goes from highest order bits of the timestamp to lowest order simple string sorting in your SQL queries can be used to order by date if you're sticking values in a database

I would use tel: (as recommended). But to have a better fallback/not display error pages I would use something like this (using jquery):

// enhance tel-links
$("a[href^='tel:']").each(function() {
    var target = "call-" + this.href.replace(/[^a-z0-9]*/gi, "");
    var link = this;

    // load in iframe to supress potential errors when protocol is not available
    $("body").append("<iframe name=\"" + target + "\" style=\"display: none\"></iframe>");
    link.target = target;

    // replace tel with callto on desktop browsers for skype fallback
    if (!navigator.userAgent.match(/(mobile)/gi)) {
        link.href = link.href.replace(/^tel:/, "callto:");
    }
});

The assumption is, that mobile browsers that have a mobile stamp in the userAgent-string have support for the tel: protocol. For the rest we replace the link with the callto: protocol to have a fallback to Skype where available.

To suppress error-pages for the unsupported protocol(s), the link is targeted to a new hidden iframe.

Unfortunately it does not seem to be possible to check, if the url has been loaded successfully in the iframe. It's seems that no error events are fired.

the Microsoft XSD inference tool is a good, free solution. Many XML editing tools, such as XmlSpy (mentioned by @Garth Gilmour) or OxygenXML Editor also have that feature. They're rather expensive, though. BizTalk Server also has an XSD inferring tool as well.

edit: I just discovered the .net XmlSchemaInference class, so if you're using .net you should consider that

Some people recommend using HTTP status codes, but I rather despise that practice. e.g. If you're doing a search engine and the provided keywords have no results, the suggestion would be to return a 404 error.

However, I consider that wrong. HTTP status codes apply to the actual browser<->server connection. Everything about the connect went perfectly. The browser made a request, the server invoked your handler script. The script returned 'no rows'. Nothing in that signifies "404 page not found" - the page WAS found.

Instead, I favor divorcing the HTTP layer from the status of your server-side operations. Instead of simply returning some text in a json string, I always return a JSON data structure which encapsulates request status and request results.

e.g. in PHP you'd have

$results = array(
   'error' => false,
   'error_msg' => 'Everything A-OK',
   'data' => array(....results of request here ...)
);
echo json_encode($results);

Then in your client-side code you'd have

if (!data.error) {
   ... got data, do something with it ...
} else {
   ... invoke error handler ...
}

If we want to not use include? this also works:

['cat','dog','horse'].select{ |x| x == 'dog' }.any?

I had a similiar problem and the only solution was rebooting vagrant which I use as dev enviroment. Beside that, not a single artisan and composer command didn't help.

I've created a module called cors-bypass, that allows you to do this without the need for a server. It uses postMessage to send cross-domain events, which is used to provide mock HTTP APIs (fetch, WebSocket, XMLHTTPRequest etc.).

It fundamentally does the same as the answer by Endless, but requires no code changes to use it.

Example usage:

import { Client, WebSocket } from 'cors-bypass'

const client = new Client()

await client.openServerInNewTab({
  serverUrl: 'http://random-domain.com/server.html',
  adapterUrl: 'https://your-site.com/adapter.html'
})

const ws = new WebSocket('ws://echo.websocket.org')
ws.onopen = () => ws.send('hello')
ws.onmessage = ({ data }) => console.log('received', data)

To extend Rodrigo's solution a little - for requests that are executed frequently, you may only want to display the loading image if the request takes more than a minimum time interval, otherwise the image will be continually popping up and quickly disappearing

var loading = false;

$.ajaxSetup({
    beforeSend: function () {
        // Display loading icon if AJAX call takes >1 second
        loading = true;
        setTimeout(function () {
            if (loading) {
                // show loading image
            }
        }, 1000);            
    },
    complete: function () {
        loading = false;
        // hide loading image
    }
});

You can't. All you can do is to make that image as small as possible and set some cache invalidation headers (Expires, Cache-Control) far in the future. Here's what Yahoo! has to say about favicon.ico requests.

Maybe not integers but small unique keys, anyway shorter then guids:

This explains better: Postman docs

Request body

While constructing requests, you would be dealing with the request body editor a lot. Postman lets you send almost any kind of HTTP request (If you can't send something, let us know!). The body editor is divided into 4 areas and has different controls depending on the body type.

form-data

multipart/form-data is the default encoding a web form uses to transfer data. This simulates filling a form on a website, and submitting it. The form-data editor lets you set key/value pairs (using the key-value editor) for your data. You can attach files to a key as well. Do note that due to restrictions of the HTML5 spec, files are not stored in history or collections. You would have to select the file again at the time of sending a request.

urlencoded

This encoding is the same as the one used in URL parameters. You just need to enter key/value pairs and Postman will encode the keys and values properly. Note that you can not upload files through this encoding mode. There might be some confusion between form-data and urlencoded so make sure to check with your API first.

raw

A raw request can contain anything. Postman doesn't touch the string entered in the raw editor except replacing environment variables. Whatever you put in the text area gets sent with the request. The raw editor lets you set the formatting type along with the correct header that you should send with the raw body. You can set the Content-Type header manually as well. Normally, you would be sending XML or JSON data here.

binary

binary data allows you to send things which you can not enter in Postman. For example, image, audio or video files. You can send text files as well. As mentioned earlier in the form-data section, you would have to reattach a file if you are loading a request through the history or the collection.

UPDATE

As pointed out by VKK, the WHATWG spec say urlencoded is the default encoding type for forms.

The invalid value default for these attributes is the application/x-www-form-urlencoded state. The missing value default for the enctype attribute is also the application/x-www-form-urlencoded state.

Personally, I really think the ternary expressions show in (JSX In Depth) are the most natural way that conforms with the ReactJs standards.

See the following example. It's a little messy at first sight but works quite well.

<div id="page">
  {this.state.banner ? (
    <div id="banner">
     <div class="another-div">
       {this.state.banner}
     </div>
    </div>
  ) : 
  null} 
  <div id="other-content">
    blah blah blah...
  </div>
</div>

You can use on input event like this:

$(document).on("input", ".numeric", function() {
    this.value = this.value.replace(/\D/g,'');
});

But, what's this code privilege?

• It works on mobile browsers(keydown and keyCode have problem).
• It works on AJAX generated content too, because We're using "on".
• Better performance than keydown, for example on paste event.

The simple solution is to avoid creating an array before piping to Out-File. Rule #1 of PowerShell is that the comma is a special delimiter, and the default behavior is to create an array. Concatenation is done like this.

$computer + "," + $Speed + "," + $Regcheck | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

This creates an array of three items.

$computer,$Speed,$Regcheck
FYKJ
100
YES

vs. concatenation of three items separated by commas.

$computer + "," + $Speed + "," + $Regcheck
FYKJ,100,YES

I downloaded a different installer "SQL Server 2014 Express with Advanced Services" and found Instance Features in it. Thanks for Alberto Solano's answer, it was really helpful.

My first installer was "SQL Server 2014 Express". It installed only SQL Management Studio and tools without Instance features. After installation "SQL Server 2014 Express with Advanced Services" my LocalDB is now alive!!!

In C# 7:

(startAngle, stopAngle) = (stopAngle, startAngle);

Your approach was not too far off, but you are only checking whether long and int are of the same size. Theoretically, they could both be 64 bits, in which case your check would fail, assuming both to be 32 bits. Here is a check that actually checks the size of the types themselves, not their relative size:

#if ((UINT_MAX) == 0xffffffffu)
    #define INT_IS32BIT
#else
    #define INT_IS64BIT
#endif
#if ((ULONG_MAX) == 0xfffffffful)
    #define LONG_IS32BIT
#else
    #define LONG_IS64BIT
#endif

In principle, you can do this for any type for which you have a system defined macro with the maximal value.

Note, that the standard requires long long to be at least 64 bits even on 32 bit systems.

Iterate through "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" keys and check their "DisplayName" values.

you can always use memset:

int myArray[10];
memset( myArray, 0, 10 * sizeof( int ));

In case anyone is wondering how to use Marionette in C#.

FirefoxProfile profile = new FirefoxProfile(); // Your custom profile
var service = FirefoxDriverService.CreateDefaultService("DirectoryContainingTheDriver", "geckodriver.exe");
// Set the binary path if you want to launch the release version of Firefox.
service.FirefoxBinaryPath = @"C:\Program Files\Mozilla Firefox\firefox.exe";
var option = new FirefoxProfileOptions(profile) { IsMarionette = true };
var driver = new FirefoxDriver(
    service,
    option,
    TimeSpan.FromSeconds(30));

Overriding FirefoxOptions to provide the function to add additional capability and set Firefox profile because selenium v53 doesn't provide that function yet.

public class FirefoxProfileOptions : FirefoxOptions
{
    private DesiredCapabilities _capabilities;

    public FirefoxProfileOptions()
        : base()
    {
        _capabilities = DesiredCapabilities.Firefox();
        _capabilities.SetCapability("marionette", this.IsMarionette);
    }

    public FirefoxProfileOptions(FirefoxProfile profile)
        : this()
    {
        _capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile.ToBase64String());
    }

    public override void AddAdditionalCapability(string capabilityName, object capabilityValue)
    {
        _capabilities.SetCapability(capabilityName, capabilityValue);
    }

    public override ICapabilities ToCapabilities()
    {
        return _capabilities;
    }
}

Note: Launching with profile doesn't work with FF 47, it works with FF 50 Nightly.

However, we tried to convert our test to use Marionette, and it's just not viable at the moment because the implementation of the driver is either not completed or buggy. I'd suggest people downgrade their Firefox at this moment.

I just solved this kind of a problem. What I've learned is:

1. you'll have to edit the my.cnf and set the bind-address = your.mysql.server.address under [mysqld]
2. comment out skip-networking field
3. restart mysqld

4. check if it's running

   mysql -u root -h your.mysql.server.address –p 
   

5. create a user (usr or anything) with % as domain and grant her access to the database in question.

   mysql> CREATE USER 'usr'@'%' IDENTIFIED BY 'some_pass';
   mysql> GRANT ALL PRIVILEGES ON testDb.* TO 'monty'@'%' WITH GRANT OPTION;
   

6. open firewall for port 3306 (you can use iptables. make sure to open port for eithe reveryone, or if you're in tight securety, then only allow the client address)

7. restart firewall/iptables

you should be able to now connect mysql server form your client server php script.

You can also run VS Code from the terminal by typing code after adding it to the path:

Launch VS Code. Open the Command Palette (??P) and type shell command to find the Shell Command: Install code command in PATH command. Mac shell commands

Restart the terminal for the new $PATH value to take effect. You'll be able to type code . in any folder to start editing files in that folder.

There are a lot of good answers but so far none of them allow a customizable character pool and work as a default value for a column. I wanted to be able to do something like this:

alter table MY_TABLE add MY_COLUMN char(20) not null
  default dbo.GenerateToken(crypt_gen_random(20))

So I came up with this. Beware of the hard-coded number 32 if you modify it.

-- Converts a varbinary of length N into a varchar of length N.
-- Recommend passing in the result of CRYPT_GEN_RANDOM(N).
create function GenerateToken(@randomBytes varbinary(max))
returns varchar(max) as begin

-- Limit to 32 chars to get an even distribution (because 32 divides 256) with easy math.
declare @allowedChars char(32);
set @allowedChars = 'abcdefghijklmnopqrstuvwxyz012345';

declare @oneByte tinyint;
declare @oneChar char(1);
declare @index int;
declare @token varchar(max);

set @index = 0;
set @token = '';

while @index < datalength(@randomBytes)
begin
    -- Get next byte, use it to index into @allowedChars, and append to @token.
    -- Note: substring is 1-based.
    set @index = @index + 1;
    select @oneByte = convert(tinyint, substring(@randomBytes, @index, 1));
    select @oneChar = substring(@allowedChars, 1 + (@oneByte % 32), 1); -- 32 is the number of @allowedChars
    select @token = @token + @oneChar;
end

return @token;

end

When using the checkbox HtmlHelper, I much prefer to work with the posted checkbox form data as an array. I don't really know why, I know the other methods work, but I think I just prefer to treat comma separated strings as an array as much as possible.

So doing a 'checked' or true test would be:

//looking for [true],[false]
bool isChecked = form.GetValues(key).Contains("true"); 

Doing a false check would be:

//looking for [false],[false] or [false]
bool isNotChecked = !form.GetValues(key).Contains("true"); 

The main difference is to use GetValues as this returns as an array.

I used this code and it works just fine

const int margin = 5;
        Rectangle rect = new Rectangle(
            Screen.PrimaryScreen.WorkingArea.X + margin,
            Screen.PrimaryScreen.WorkingArea.Y + margin,
            Screen.PrimaryScreen.WorkingArea.Width - 2 * margin,
            Screen.PrimaryScreen.WorkingArea.Height - 2 * (margin - 7));
        this.Bounds = rect;

You need the ip of the other pc and do:

scp user@ip_of_remote_pc:/home/user/stuff.php /Users/djorge/Desktop

it will ask you for 'user's password on the other pc.

You are searching/reading the file "fiel.txt" in the execution directory (where the class are stored, i think).

If you whish to read the file in a given directory, you have to says so :

File file = new File(System.getProperty("user.dir")+"/"+"file.txt");

You could also give the directory with a relative path, eg "./images/photo.gif) for a subdirecory for example.

Note that there is also a property for the separator (hard-coded to "/" in my exemple)

regards Guillaume

This is for latest iOS Versions(Modified with Xcode 9.3, Swift 4.1). Below are all the stages which makes the lifecycle of a UIViewController complete.

• loadView()

• loadViewIfNeeded()

• viewDidLoad()

• viewWillAppear(_ animated: Bool)

• viewWillLayoutSubviews()

• viewDidLayoutSubviews()

• viewDidAppear(_ animated: Bool)

• viewWillDisappear(_ animated: Bool)

• viewDidDisappear(_ animated: Bool)

Let me explain all those stages.

1. loadView

This event creates/loads the view that the controller manages. It can load from an associated nib file or an empty UIView if null was found. This makes it a good place to create your views in code programmatically.

This is where subclasses should create their custom view hierarchy if they aren't using a nib. Should never be called directly. Only override this method when you programmatically create views and assign the root view to the view property Don't call super method when you override loadView

2. loadViewIfNeeded

If incase the view of current viewController has not been set yet then this method will load the view but remember, this is only available in iOS >=9.0. So if you are supporting iOS <9.0 then don't expect it to come into the picture.

Loads the view controller's view if it has not already been set.

3. viewDidLoad

The viewDidLoad event is only called when the view is created and loaded into memory but the bounds for the view are not defined yet. This is a good place to initialise the objects that the view controller is going to use.

Called after the view has been loaded. For view controllers created in code, this is after -loadView. For view controllers unarchived from a nib, this is after the view is set.

4. viewWillAppear

This event notifies the viewController whenever the view appears on the screen. In this step the view has bounds that are defined but the orientation is not set.

Called when the view is about to made visible. Default does nothing.

5. viewWillLayoutSubviews

This is the first step in the lifecycle where the bounds are finalised. If you are not using constraints or Auto Layout you probably want to update the subviews here. This is only available in iOS >=5.0. So if you are supporting iOS <5.0 then don't expect it to come into the picture.

Called just before the view controller's view's layoutSubviews method is invoked. Subclasses can implement as necessary. The default is a nop.

6. viewDidLayoutSubviews

This event notifies the view controller that the subviews have been setup. It is a good place to make any changes to the subviews after they have been set. This is only available in iOS >=5.0. So if you are supporting iOS <5.0 then don't expect it to come into the picture.

Called just after the view controller's view's layoutSubviews method is invoked. Subclasses can implement as necessary. The default is a nop.

7. viewDidAppear

The viewDidAppear event fires after the view is presented on the screen. Which makes it a good place to get data from a backend service or database.

Called when the view has been fully transitioned onto the screen. Default does nothing

8. viewWillDisappear

The viewWillDisappear event fires when the view of presented viewController is about to disappear, dismiss, cover or hide behind other viewController. This is a good place where you can restrict your network calls, invalidate timer or release objects which is bound to that viewController.

Called when the view is dismissed, covered or otherwise hidden.

9. viewDidDisappear

This is the last step of the lifecycle that anyone can address as this event fires just after the view of presented viewController has been disappeared, dismissed, covered or hidden.

Called after the view was dismissed, covered or otherwise hidden. Default does nothing

Now as per Apple when you are implementing this methods you should remember to call super implementation of that specific method.

If you subclass UIViewController, you must call the super implementation of this method, even if you aren't using a NIB. (As a convenience, the default init method will do this for you, and specify nil for both of this methods arguments.) In the specified NIB, the File's Owner proxy should have its class set to your view controller subclass, with the view outlet connected to the main view. If you invoke this method with a nil nib name, then this class' -loadView method will attempt to load a NIB whose name is the same as your view controller's class. If no such NIB in fact exists then you must either call -setView: before -view is invoked, or override the -loadView method to set up your views programatically.

Hope this helped. Thanks.

UPDATE - As @ThomasW pointed inside comment viewWillLayoutSubviews and viewDidLayoutSubviews will also be called at other times when subviews of the main view are loaded, for example when cells of a table view or collection view are loaded.

UPDATE - As @Maria pointed inside comment, description of loadView was updated

As per Android official Blogs : https://android-developers.googleblog.com/2011/06/things-that-cannot-change.html

We can say that:

• If the manifest package name has changed, the new application will be installed alongside the old application, so they both co-exist on the user’s device at the same time.

• If the signing certificate changes, trying to install the new application on to the device will fail until the old version is uninstalled.

As per Google App Update check list : https://support.google.com/googleplay/android-developer/answer/113476?hl=en

Update your apps

Prepare your APK

When you're ready to make changes to your APK, make sure to update your app’s version code as well so that existing users will receive your update.

Use the following checklist to make sure your new APK is ready to update your existing users:

• The package name of the updated APK needs to be the same as the current version.
• The version code needs to be greater than that current version. Learn more about versioning your applications.
• The updated APK needs to be signed with the same signature as the current version.

To verify that your APK is using the same certification as the previous version, you can run the following command on both APKs and compare the results:

$ jarsigner -verify -verbose -certs my_application.apk

If the results are identical, you’re using the same key and are ready to continue. If the results are different, you will need to re-sign the APK with the correct key.

Learn more about signing your applications

Upload your APK Once your APK is ready, you can create a new release.

More Suggestive answer supporting rmaddy's answer as our primary purpose is to delete unnecessary file and folder:

1. Delete this folder after every few days interval. Most of the time, it occupy huge space!

     ~/Library/Developer/Xcode/DerivedData
   

2. All your targets are kept in the archived form in Archives folder. Before you decide to delete contents of this folder, here is a warning - if you want to be able to debug deployed versions of your App, you shouldn’t delete the archives. Xcode will manage of archives and creates new file when new build is archived.

     ~/Library/Developer/Xcode/Archives
   

3. iOS Device Support folder creates a subfolder with the device version as an identifier when you attach the device. Most of the time it’s just old stuff. Keep the latest version and rest of them can be deleted (if you don’t have an app that runs on 5.1.1, there’s no reason to keep the 5.1.1 directory/directories). If you really don't need these, delete. But we should keep a few although we test app from device mostly.

   ~/Library/Developer/Xcode/iOS DeviceSupport
   

4. Core Simulator folder is familiar for many Xcode users. It’s simulator’s territory; that's where it stores app data. It’s obvious that you can toss the older version simulator folder/folders if you no longer support your apps for those versions. As it is user data, no big issue if you delete it completely but it’s safer to use ‘Reset Content and Settings’ option from the menu to delete all of your app data in a Simulator.

     ~/Library/Developer/CoreSimulator 
   

(Here's a handy shell command for step 5: xcrun simctl delete unavailable )

5. Caches are always safe to delete since they will be recreated as necessary. This isn’t a directory; it’s a file of kind Xcode Project. Delete away!

   ~/Library/Caches/com.apple.dt.Xcode
   

6. Additionally, Apple iOS device automatically syncs specific files and settings to your Mac every time they are connected to your Mac machine. To be on safe side, it’s wise to use Devices pane of iTunes preferences to delete older backups; you should be retaining your most recent back-ups off course.

    ~/Library/Application Support/MobileSync/Backup

I got back about 40GB!

You can define sScrollX : "100%" to force dataTables to keep the column widths :

..
 sScrollX: "100%", //<-- here
 aoColumns : [
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
    ],
...

I think that it's around 2GB. While the answer by Pete Kirkham is very interesting and probably holds truth, I have allocated upwards of 3GB without error, however it did not use 3GB in practice. That might explain why you were able to allocate 2.5 GB on 2GB RAM with no swap space. In practice, it wasn't using 2.5GB.

Wrap time and the command you are timing in a set of brackets.

For example, the following times ls and writes the result of ls and the results of the timing into outfile:

$ (time ls) > outfile 2>&1

Or, if you'd like to separate the output of the command from the captured output from time:

$ (time ls) > ls_results 2> time_results

It reads Hello World (cat), replaces all (g) occurrences of % by $ and (over)writes it to /etc/init.d/dropbox as root.

Eclipse Juno has a good way for it. You just do the cmd+/

Yes, you'll need arrays.

var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

var day = days[ now.getDay() ];
var month = months[ now.getMonth() ];

Or you can use the date.js library.

EDIT:

If you're going to use these frequently, you may want to extend Date.prototype for accessibility.

(function() {
    var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];

    var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

    Date.prototype.getMonthName = function() {
        return months[ this.getMonth() ];
    };
    Date.prototype.getDayName = function() {
        return days[ this.getDay() ];
    };
})();

var now = new Date();

var day = now.getDayName();
var month = now.getMonthName();

If anybody is looking for Java firestore sdk solution to add items in array field:

List<String> list = java.util.Arrays.asList("A", "B");
Object[] fieldsToUpdate = list.toArray();
DocumentReference docRef = getCollection().document("docId");
docRef.update(fieldName, FieldValue.arrayUnion(fieldsToUpdate));

To delete items from array user: FieldValue.arrayRemove()

You could use:

import os
path = 'the path you want'
os.environ['PATH'] += ':'+path

You can use git stash to save the current repository before doing the commit you want to make (after merging the changes from the upstream repo with git stash pop). I had to do this yesterday when I had the same problem.

If you VS solution contains several projects, select all of them in the right pane, and press "properties". Then go to C++ -> Code Generation and chose one Run Time library option for all of them

It is typically not what you want to do. You want to run your compilation in an editor that has support for reading the output of the compiler and going to the file/line char that has the problems. It works in all editors worth considering. Here is the emacs setup:

@Alex aw that's a bummer. What if in your iframe you had an html document that looked like:

  <head>
    <meta http-equiv="refresh" content="0;url=/pdfs/somepdf.pdf" />
  </head>
  <body>

Definitely a hack, but it might work for Firefox. Although I wonder if the load event would fire too soon in that case.

Generally constructors are for initializing non-static members of particular class with respect to object.

There is no object creation for interface as there is only declared methods but not defined methods. Why we can’t create object to declared methods is-object creation is nothing but allocating some memory (in heap memory) for non-static members.

JVM will create memory for members which are fully developed and ready to use.Based on those members , JVM calculates how much of memory required for them and creates memory.

Incase of declared methods, JVM is unable to calculate the how much memory will required to these declared methods as the implementation will be in future which is not done by this time. so object creation is not possible for interface.

conclusion:

without object creation, there is no chance to initialize non-static members through a constructor.That is why constructor is not allowed inside a interface.(as there is no use of constructor inside a interface)

Kotlin Solution

The base way to handle it in Kotlin is:

edittext.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        callback.invoke()
        true
    }
    false
}

Kotlin Extension

Use this to just call edittext.onDone{/*action*/} in your main code. Makes your code far more readable and maintainable

fun EditText.onDone(callback: () -> Unit) {
    setOnEditorActionListener { _, actionId, _ ->
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            callback.invoke()
            true
        }
        false
    }
}

Don't forget to add these options to your edittext

<EditText ...
    android:imeOptions="actionDone"
    android:inputType="text"/>

If you need inputType="textMultiLine" support, read this post

Use Access's VBA function Replace(text, find, replacement):

result = Replace("Some sentence containing Avenue in it.", "Avenue", "Ave")

I needed to have a button handler that created a form post to another application within the client's browser. I landed on this question but didn't see an answer that suited my scenario. This is what I came up with:

      protected void Button1_Click(object sender, EventArgs e)
        {

            var formPostText = @"<html><body><div>
<form method=""POST"" action=""OtherLogin.aspx"" name=""frm2Post"">
  <input type=""hidden"" name=""field1"" value=""" + TextBox1.Text + @""" /> 
  <input type=""hidden"" name=""field2"" value=""" + TextBox2.Text + @""" /> 
</form></div><script type=""text/javascript"">document.frm2Post.submit();</script></body></html>
";
            Response.Write(formPostText);
        }

Try this code:

$('#iframe').attr('src', $('#iframe').attr('src'));

• Kotlin Version via Extension Property

If you are using kotlin, it's pretty easy to format file size by these extension properties. It is loop-free and completely based on pure math.

HumanizeUtils.kt

import java.io.File
import kotlin.math.log2
import kotlin.math.pow

/**
 * @author aminography
 */

val File.formatSize: String
    get() = length().formatAsFileSize

val Int.formatAsFileSize: String
    get() = toLong().formatAsFileSize

val Long.formatAsFileSize: String
    get() = log2(if (this != 0L) toDouble() else 1.0).toInt().div(10).let {
        val precision = when (it) {
            0 -> 0; 1 -> 1; else -> 2
        }
        val prefix = arrayOf("", "K", "M", "G", "T", "P", "E", "Z", "Y")
        String.format("%.${precision}f ${prefix[it]}B", toDouble() / 2.0.pow(it * 10.0))
    }

Usage:

println("0:          " + 0.formatAsFileSize)
println("170:        " + 170.formatAsFileSize)
println("14356:      " + 14356.formatAsFileSize)
println("968542985:  " + 968542985.formatAsFileSize)
println("8729842496: " + 8729842496.formatAsFileSize)

println("file: " + file.formatSize)

Result:

0:          0 B
170:        170 B
14356:      14.0 KB
968542985:  923.67 MB
8729842496: 8.13 GB

Simply you can use this..

$("ul li a").click(function() {
  $(this).parent().find(">ul")...Something;
}

Super dated, but certainly good ways to accomodate this. Just wrote this up for a project and figured I'd share. Similar to some of the others, varied in style.

var ObjectListener = function(prop, value) {

  if (value === undefined) value = null;

  var obj = {};    
  obj.internal = value;
  obj.watcher = (function(x) {});
  obj.emit = function(fn) {
    obj.watch = fn;
  };

  var setter = {};
  setter.enumerable = true;
  setter.configurable = true;
  setter.set = function(x) {
    obj.internal = x;
    obj.watcher(x);
  };

  var getter = {};
  getter.enumerable = true;
  getter.configurable = true;
  getter.get = function() {
    return obj.internal;
  };

  return (obj,
    Object.defineProperty(obj, prop, setter),
    Object.defineProperty(obj, prop, getter),
    obj.emit, obj);

};


user._licenseXYZ = ObjectListener(testProp);
user._licenseXYZ.emit(testLog);

function testLog() {
  return function() {
    return console.log([
        'user._licenseXYZ.testProp was updated to ', value
    ].join('');
  };
}


user._licenseXYZ.testProp = 123;

   .search-table-outter {border:2px solid red; overflow-x:scroll;}
   .search-table{table-layout: fixed; margin:40px auto 0px auto;   }
   .search-table, td, th{border-collapse:collapse; border:1px solid #777;}
   th{padding:20px 7px; font-size:15px; color:#444; background:#66C2E0;}
   td{padding:5px 10px; height:35px;}

You should provide scroll in div.

There is a shortcut in Visual Studio, because it supports Git out of the box in 2015 or above. For new solutions (or some which don't have .git folder) use source control features in Solution Explorer:

Right-click on your solution and select Add Solution to Source Control... item in the popup menu.

It automatically initializes .git repository, adds .gitignore with necessary things to your solution and even .gitattributes file (line endings, etc.).

The text will appeared in the VS console:

A new Git repository has been created for you in C:\<path to your solution>
Commit ______ created locally in repository.

Done!

Sorting in an ORDER BY is done by the first column, and then by each additional column in the specified statement.

For instance, consider the following data:

Column1    Column2
=======    =======
1          Smith
2          Jones
1          Anderson
3          Andrews

The query

SELECT Column1, Column2 FROM thedata ORDER BY Column1, Column2

would first sort by all of the values in Column1

and then sort the columns by Column2 to produce this:

Column1    Column2
=======    =======
1          Anderson
1          Smith
2          Jones
3          Andrews

In other words, the data is first sorted in Column1 order, and then each subset (Column1 rows that have 1 as their value) are sorted in order of the second column.

The difference between the two statements you posted is that the rows in the first one would be sorted first by prod_price (price order, from lowest to highest), and then by order of name (meaning that if two items have the same price, the one with the lower alpha value for name would be listed first), while the second would sort in name order only (meaning that prices would appear in order based on the prod_name without regard for price).

You can try

echo "<SCRIPT>alert(\"Login Successful Redirecting To Previous Page \");history.go(-2)</SCRIPT>";

Or

echo "<SCRIPT>alert(\"Login Successful Redirecting To Previous Page \");history.go(-1)</SCRIPT>";

I am just adding example here because I think examples make it easier to understand.

In printf() they behave identically so you can use any either %d or %i. But they behave differently in scanf().

For example:

int main()
{
    int num,num2;
    scanf("%d%i",&num,&num2);// reading num using %d and num2 using %i

    printf("%d\t%d",num,num2);
    return 0;
}

Output:

You can see the different results for identical inputs.

num:

We are reading num using %d so when we enter 010 it ignores the first 0 and treats it as decimal 10.

num2:

We are reading num2 using %i.

That means it will treat decimals, octals, and hexadecimals differently.

When it give num2 010 it sees the leading 0 and parses it as octal.

When we print it using %d it prints the decimal equivalent of octal 010 which is 8.

I did not see any reference to Raphael.js. So I thought I'd include it here. Raphael.js is backwards compatible all the way back to IE5 and a very early Firefox as well as all of the rest of the browsers. It uses SVG when it can and VML when it can not. What you do with it is to draw onto a canvas. Some browsers will even let you select the text that is generated. Raphael.js can be found here:

http://raphaeljs.com/

It can be as simple as creating your paper drawing area, specifying the font, font-weight, size, etc... and then telling it to put your string of text onto the paper. I am not sure if it gets around the licensing issues or not but it is drawing the text so I'm fairly certain it does circumvent the licensing issues. But check with your lawyer to be sure. :-)

With countries, languages or currency you may use emojis.

Works with pretty much every browser/OS that supports the use of emojis.

In C, if time efficiency is crucial and integer overflows will wrap, one could do if ((unsigned)(value-min) <= (max-min)) .... If 'max' and 'min' are independent variables, the extra subtraction for (max-min) will waste time, but if that expression can be precomputed at compile time, or if it can be computed once at run-time to test many numbers against the same range, the above expression may be computed efficiently even in the case where the value is within range (if a large fraction of values will be below the valid range, it may be faster to use if ((value >= min) && (value <= max)) ... because it will exit early if value is less than min).

Before using an implementation like that, though, benchmark one one's target machine. On some processors, the two-part expression may be faster in all cases since the two comparisons may be done independently whereas in the subtract-and-compare method the subtraction has to complete before the compare can execute.

The answer depends upon the degree of confidence you place in the data and how your data is being used. For example, if you're using it for mailing or shipping, you'll want to be be confident that the data is correct. If you're just using it as another fraud-prevention mechanism then you could potentially allow a degree of error to creep into the data.

If you want any degree of real accuracy, you're need to go with a service that does real address verification and you're going to have to pay for it. As has been mentioned by Adam, address verification and validation at first seems simple and easy, but it's a black hole fraught with challenges and, unless you've some underlying data to work with, virtually impossible to do by yourself. Trust me, you're actually saving money by using a service. You're welcome to go down this road yourself to experience what I mean, but I can guarantee you'll see the light, so to speak, after even a few hours (or days) of spinning your wheels.

I should mention that I'm the founder of SmartyStreets. We do address validation and verification addresses and we offer this for the USA and international as well. I'm more than happy to personally answer any questions you have on the topic of address cleansing, standardization, and validation.

I couldn't find a single answer or a section in the official Django docs that had all the information I needed to override/extend the default admin templates, so I'm writing this answer as a complete guide, hoping that it would be helpful for others in the future.

Assuming the standard Django project structure:

mysite-container/         # project container directory
    manage.py
    mysite/               # project package
        __init__.py
        admin.py
        apps.py
        settings.py
        urls.py
        wsgi.py
    app1/
    app2/
    ...
    static/
    templates/

Here's what you need to do:

1. In mysite/admin.py, create a sub-class of AdminSite:

   from django.contrib.admin import AdminSite
   
   
   class CustomAdminSite(AdminSite):
       # set values for `site_header`, `site_title`, `index_title` etc.
       site_header = 'Custom Admin Site'
       ...
   
       # extend / override admin views, such as `index()`
       def index(self, request, extra_context=None):
           extra_context = extra_context or {}
   
           # do whatever you want to do and save the values in `extra_context`
           extra_context['world'] = 'Earth'
   
           return super(CustomAdminSite, self).index(request, extra_context)
   
   
   custom_admin_site = CustomAdminSite()
   

   Make sure to import custom_admin_site in the admin.py of your apps and register your models on it to display them on your customized admin site (if you want to).

2. In mysite/apps.py, create a sub-class of AdminConfig and set default_site to admin.CustomAdminSite from the previous step:

   from django.contrib.admin.apps import AdminConfig
   
   
   class CustomAdminConfig(AdminConfig):
       default_site = 'admin.CustomAdminSite'
   

3. In mysite/settings.py, replace django.admin.site in INSTALLED_APPS with apps.CustomAdminConfig (your custom admin app config from the previous step).

4. In mysite/urls.py, replace admin.site.urls from the admin URL to custom_admin_site.urls

   from .admin import custom_admin_site
   
   
   urlpatterns = [
       ...
       path('admin/', custom_admin_site.urls),
       # for Django 1.x versions: url(r'^admin/', include(custom_admin_site.urls)),
       ...
   ]
   

5. Create the template you want to modify in your templates directory, maintaining the default Django admin templates directory structure as specified in the docs. For example, if you were modifying admin/index.html, create the file templates/admin/index.html.

   All of the existing templates can be modified this way, and their names and structures can be found in Django's source code.

6. Now you can either override the template by writing it from scratch or extend it and then override/extend specific blocks.

   For example, if you wanted to keep everything as-is but wanted to override the content block (which on the index page lists the apps and their models that you registered), add the following to templates/admin/index.html:

   {% extends 'admin/index.html' %}
   
   {% block content %}
     <h1>
       Hello, {{ world }}!
     </h1>
   {% endblock %}
   

   To preserve the original contents of a block, add {{ block.super }} wherever you want the original contents to be displayed:

   {% extends 'admin/index.html' %}
   
   {% block content %}
     <h1>
       Hello, {{ world }}!
     </h1>
     {{ block.super }}
   {% endblock %}
   

   You can also add custom styles and scripts by modifying the extrastyle and extrahead blocks.

Just put

export HOME=/blah/whatever

at the point in the script where you want the change to happen. Since each process has its own set of environment variables, this definition will automatically cease to have any significance when the script terminates (and with it the instance of bash that has a changed environment).

The real problem is that the variable line always has a value. The test for "no matches found" is whether there is a match so the code "if line == None:" should be replaced with "else:"

Yes, it's possible to use inline if-expressions:

{{ 'Update' if files else 'Continue' }}

I've been able to input values within the character ":

db_user="postgresql"
db_passwd="this,is,my,password"

You can try something like this:

HSSFSheet summarySheet = wb.createSheet();
summarySheet.setColumnWidth(short column, short width);

Here params are:column number in sheet and its width But,the units of width are pretty small, you can try 4000 for example.

To provide some timing figures behind the different approaches, consider the following code. The get() is my custom addition to Python's setobject.c, being just a pop() without removing the element.

from timeit import *

stats = ["for i in xrange(1000): iter(s).next()   ",
         "for i in xrange(1000): \n\tfor x in s: \n\t\tbreak",
         "for i in xrange(1000): s.add(s.pop())   ",
         "for i in xrange(1000): s.get()          "]

for stat in stats:
    t = Timer(stat, setup="s=set(range(100))")
    try:
        print "Time for %s:\t %f"%(stat, t.timeit(number=1000))
    except:
        t.print_exc()

The output is:

$ ./test_get.py
Time for for i in xrange(1000): iter(s).next()   :       0.433080
Time for for i in xrange(1000):
        for x in s:
                break:   0.148695
Time for for i in xrange(1000): s.add(s.pop())   :       0.317418
Time for for i in xrange(1000): s.get()          :       0.146673

This means that the for/break solution is the fastest (sometimes faster than the custom get() solution).

Use String.substring(beginIndex, endIndex)

str.substring(0, str.length() - 2);

The substring begins at the specified beginIndex and extends to the character at index (endIndex - 1)

You can use Drawable instead of Uri.

   ImageView iv=(ImageView)findViewById(R.id.imageView1);
   String pathName = "/external/images/media/470939"; 
   Drawable image = Drawable.createFromPath(pathName);
   iv.setImageDrawable(image);

This would work.

Do you have _timestamp enabled in your doc mapping?

{
    "doctype": {
        "_timestamp": {
            "enabled": "true",
            "store": "yes"
        },
        "properties": {
            ...
        }
    }
}

You can check your mapping here:

http://localhost:9200/_all/_mapping

If so I think this might work to get most recent:

{
  "query": {
    "match_all": {}
  },
  "size": 1,
  "sort": [
    {
      "_timestamp": {
        "order": "desc"
      }
    }
  ]
}

Or:

SELECT SUM(foo), DATE(mydate) mydate FROM a_table GROUP BY mydate;

More efficient (I think.) Because you don't have to cast mydate twice per row.

Another possibility is too many threads. We just ran into this error message when running a test harness against an app that uses a thread pool. We used

watch -n 5 -d "ps -eL <java_pid> | wc -l"

to watch the ongoing count of Linux native threads running within the given Java process ID. After this hit about 1,000 (for us--YMMV), we started getting the error message you mention.

Found another solution for the same. It will be more helpful.

START C:\"Program Files (x86)"\Test\"Test Automation"\finger.exe ConfigFile="C:\Users\PCName\Desktop\Automation\Documents\Validation_ZoneWise_Default.finger.Config"

finger.exe is a parent program that is calling config solution. Note: if your path folder name consists of spaces, then do not forget to add "".

To find the version of the java in the classfiles I used:

javap -verbose <classname>

which announces the version at the start as

minor version: 0
major version: 49

which corresponds to Java 1.5

Okay, it took me a while to see this, but there's no way this compiles:

return String.(ConfigurationManager.AppSettings[paramName]);

You're not even calling a method on the String type. Just do this:

return ConfigurationManager.AppSettings[paramName];

The AppSettings KeyValuePair already returns a string. If the name doesn't exist, it will return null.

Based on your edit you have not yet added a Reference to the System.Configuration assembly for the project you're working in.

Let us add this workaround that works on my laptop!

Mac with Osx Mojave 10.14.5

Mysql 8.0.17 was installed with homebrew

• I run the following command to locate the path of mysql

  brew info mysql

• Once the path is known, I run this :

  /usr/local/Cellar/mysql/8.0.17/bin/mysqld_safe --skip-grant-table

• In another terminal I run :

  mysql -u root

• Inside that terminal, I changed the root password using :

  update mysql.user set authentication_string='NewPassword' where user='root';

• and to finish I run :

  FLUSH PRIVILEGES;

And voila the password was reset.

Index types

It is possible to denote obj as any, but that defeats the whole purpose of using typescript. obj = {} implies obj is an Object. Marking it as any makes no sense. To accomplish the desired consistency an interface could be defined as follows.

interface LooseObject {
    [key: string]: any
}

var obj: LooseObject = {};

OR to make it compact:

var obj: {[k: string]: any} = {};

LooseObject can accept fields with any string as key and any type as value.

obj.prop = "value";
obj.prop2 = 88;

The real elegance of this solution is that you can include typesafe fields in the interface.

interface MyType {
    typesafeProp1?: number,
    requiredProp1: string,
    [key: string]: any
}

var obj: MyType ;
obj = { requiredProp1: "foo"}; // valid
obj = {} // error. 'requiredProp1' is missing
obj.typesafeProp1 = "bar" // error. typesafeProp1 should be a number

obj.prop = "value";
obj.prop2 = 88;

Record<Keys,Type> utility type

Update (August 2020): @transang brought this up in comments

Record<Keys,Type> is a Utility type in typescript. It is a much cleaner alternative for key-value pairs where property-names are not known. It's worth noting that Record<Keys,Type> is a named alias to {[k: Keys]: Type} where Keys and Type are generics. IMO, this makes it worth mentioning here

For comparison,

var obj: {[k: string]: any} = {};

becomes

var obj: Record<string,any> = {}

MyType can now be defined by extending Record type

interface MyType extends Record<string,any> {
    typesafeProp1?: number,
    requiredProp1: string,
}

While this answers the Original question, the answer here by @GreeneCreations might give another perspective on how to approach the problem.

1. You seem to be including one C file from anther. #include should normally be used with header files only.

2. Within the definition of struct ast_node you refer to struct AST_NODE, which doesn't exist. C is case-sensitive.

Use the mkdtemp() function from the tempfile module:

import tempfile
import shutil

dirpath = tempfile.mkdtemp()
# ... do stuff with dirpath
shutil.rmtree(dirpath)

Try this:

if (!emailRegistration.matches("[a-zA-Z0-9._-]+@[a-z]+\.[a-z]+")) {
 editTextEmail.setError("Invalid Email Address");
}

2.51 * 100 = 250.999999999997

The int() function simply truncates the number at the decimal point, giving 250. Use

int(round(2.51*100)) 

to get 251 as an integer. In general, floating point numbers cannot be represented exactly. One should therefore be careful of round-off errors. As mentioned, this is not a Python-specific problem. It's a recurring problem in all computer languages.

There may be confusion between class privates and module privates.

A module private starts with one underscore
Such a element is not copied along when using the from <module_name> import * form of the import command; it is however imported if using the import <moudule_name> syntax (see Ben Wilhelm's answer)
Simply remove one underscore from the a.__num of the question's example and it won't show in modules that import a.py using the from a import * syntax.

A class private starts with two underscores (aka dunder i.e. d-ouble under-score)
Such a variable has its name "mangled" to include the classname etc.
It can still be accessed outside of the class logic, through the mangled name.
Although the name mangling can serve as a mild prevention device against unauthorized access, its main purpose is to prevent possible name collisions with class members of the ancestor classes. See Alex Martelli's funny but accurate reference to consenting adults as he describes the convention used in regards to these variables.

>>> class Foo(object):
...    __bar = 99
...    def PrintBar(self):
...        print(self.__bar)
...
>>> myFoo = Foo()
>>> myFoo.__bar  #direct attempt no go
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Foo' object has no attribute '__bar'
>>> myFoo.PrintBar()  # the class itself of course can access it
99
>>> dir(Foo)    # yet can see it
['PrintBar', '_Foo__bar', '__class__', '__delattr__', '__dict__', '__doc__', '__
format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__
', '__subclasshook__', '__weakref__']
>>> myFoo._Foo__bar  #and get to it by its mangled name !  (but I shouldn't!!!)
99
>>>

// First Get DataTable as dt
// DataRowComparer Compare columns numbers in each row & data in each row

IEnumerable<DataRow> Distinct = dt.AsEnumerable().Distinct(DataRowComparer.Default);

foreach (DataRow row in Distinct)
{
    Console.WriteLine("{0,-15} {1,-15}",
        row.Field<int>(0),
        row.Field<string>(1)); 
}

From the definition in objc.h:

#if (TARGET_OS_IPHONE && __LP64__)  ||  TARGET_OS_WATCH
typedef bool BOOL;
#else
typedef signed char BOOL; 
// BOOL is explicitly signed so @encode(BOOL) == "c" rather than "C" 
// even if -funsigned-char is used.
#endif

#define YES ((BOOL)1)
#define NO  ((BOOL)0)

So, yes, you can assume that BOOL is a char. You can use the (C99) bool type, but all of Apple's Objective-C frameworks and most Objective-C/Cocoa code uses BOOL, so you'll save yourself headache if the typedef ever changes by just using BOOL.

Uncommon but may help some.

ensure you're using [HttpPut] from System.Web.Http

We were getting a 'Method not allowed' 405, on a HttpPut decorrated method.

Our problem would seem to be uncommon, as we accidentally used the [HttpPut] attribute from System.Web.Mvc and not System.Web.Http

The reason being, resharper suggested the .Mvc version, where-as usually System.Web.Http is already referenced when you derive directly from ApiController we were using a class that extended ApiController.

If i understand correctly, can't you simply use:

foreach($arr as $key=>$value)
{
  echo $key;
}

See PHP manual

To quickly find a meaningful error message by inspecting the error during debugging:

• Add a quick watch for:

  ((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors
  

• Drill down into EntityValidationErrors like this:

  (collection item e.g. [0]) > ValidationErrors > (collection item e.g. [0]) > ErrorMessage

Why not use insertAdjacentHTML

for example:

// <div id="one">one</div> 
var d1 = document.getElementById('one'); 
d1.insertAdjacentHTML('afterend', '<div id="two">two</div>');

// At this point, the new structure is:
// <div id="one">one</div><div id="two">two</div>here

At the time the compiler encounters the call to swapCase in main(), it does not know about the function swapCase, so it reports an error. You can either move the definition of swapCase above main, or declare swap case above main:

void swapCase(char* name);

Also, the 32 in swapCase causes the reader to pause and wonder. The comment helps! In this context, it would add clarity to write

if ('A' <= name[i] && name[i] <= 'Z')
    name[i] += 'a' - 'A';
else if ('a' <= name[i] && name[i] <= 'z')
    name[i] += 'A' - 'a';

The construction in my if-tests is a matter of personal style. Yours were just fine. The main thing is the way to modify name[i] -- using the difference in 'a' vs. 'A' makes it more obvious what is going on, and nobody has to wonder if the '32' is actually correct.

Good luck learning!

If your main objective is doing math, SymPy provides an excellent approach to functional latex expressions that look great.

You could also look at using OpenRowSet with the CSV text file data provider.

This should be possible with any version of SQL Server >= 2005 although you need to enable the feature.

In your view template, set a default value:

f.text_field :password, :value => "password"

In your Javascript (assuming jquery here):

$(document).ready(function() {
  //add a handler to remove the text
});

The first way is the older standard. The second method was introduced in SQL-92, http://en.wikipedia.org/wiki/SQL. The complete standard can be viewed at http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt .

It took many years before database companies adopted the SQL-92 standard.

So the reason why the second method is preferred, it is the SQL standard according the ANSI and ISO standards committee.

You can use -O- (uppercase o) to redirect content to the stdout (standard output) or to a file (even special files like /dev/null /dev/stderr /dev/stdout )

wget -O- http://yourdomain.com

Or:

wget -O- http://yourdomain.com > /dev/null

Or: (same result as last command)

wget -O/dev/null http://yourdomain.com

In IIS you can declare the mime type for WOFF2 font files by adding the following to your project's web.config:

<system.webServer>
  <staticContent>
    <remove fileExtension=".woff2" />
    <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
  </staticContent>
</system.webServer>

Update: The mime type may be changing according to the latest W3C Editor's Draft WOFF2 spec. See Appendix A: Internet Media Type Registration section 6.5. WOFF 2.0 which states the latest proposed format is font/woff2

Just extend your formula out a little bit:

dateadd(day, -1,
    dateadd(month, 1,
        cast(month('5/15/2009') as varchar(2)) + 
        '/1/' + 
        cast(year('5/15/2009') as varchar(4)))

If you are using any spreadsheet application there is a basic function if() with syntax:

if(<condition>, <yes>, <no>)

Syntax is exactly the same for ifelse() in R:

ifelse(<condition>, <yes>, <no>)

The only difference to if() in spreadsheet application is that R ifelse() is vectorized (takes vectors as input and return vector on output). Consider the following comparison of formulas in spreadsheet application and in R for an example where we would like to compare if a > b and return 1 if yes and 0 if not.

In spreadsheet:

  A  B C
1 3  1 =if(A1 > B1, 1, 0)
2 2  2 =if(A2 > B2, 1, 0)
3 1  3 =if(A3 > B3, 1, 0)

In R:

> a <- 3:1; b <- 1:3
> ifelse(a > b, 1, 0)
[1] 1 0 0

ifelse() can be nested in many ways:

ifelse(<condition>, <yes>, ifelse(<condition>, <yes>, <no>))

ifelse(<condition>, ifelse(<condition>, <yes>, <no>), <no>)

ifelse(<condition>, 
       ifelse(<condition>, <yes>, <no>), 
       ifelse(<condition>, <yes>, <no>)
      )

ifelse(<condition>, <yes>, 
       ifelse(<condition>, <yes>, 
              ifelse(<condition>, <yes>, <no>)
             )
       )

To calculate column idnat2 you can:

df <- read.table(header=TRUE, text="
idnat idbp idnat2
french mainland mainland
french colony overseas
french overseas overseas
foreign foreign foreign"
)

with(df, 
     ifelse(idnat=="french",
       ifelse(idbp %in% c("overseas","colony"),"overseas","mainland"),"foreign")
     )

R Documentation

What is the condition has length > 1 and only the first element will be used? Let's see:

> # What is first condition really testing?
> with(df, idnat=="french")
[1]  TRUE  TRUE  TRUE FALSE
> # This is result of vectorized function - equality of all elements in idnat and 
> # string "french" is tested.
> # Vector of logical values is returned (has the same length as idnat)
> df$idnat2 <- with(df,
+   if(idnat=="french"){
+   idnat2 <- "xxx"
+   }
+   )
Warning message:
In if (idnat == "french") { :
  the condition has length > 1 and only the first element will be used
> # Note that the first element of comparison is TRUE and that's whay we get:
> df
    idnat     idbp idnat2
1  french mainland    xxx
2  french   colony    xxx
3  french overseas    xxx
4 foreign  foreign    xxx
> # There is really logic in it, you have to get used to it

Can I still use if()? Yes, you can, but the syntax is not so cool :)

test <- function(x) {
  if(x=="french") {
    "french"
  } else{
    "not really french"
  }
}

apply(array(df[["idnat"]]),MARGIN=1, FUN=test)

If you are familiar with SQL, you can also use CASE statement in sqldf package.

As said here and i quote:

just change this line on config.inc.php

$cfg['Servers'][$i]['auth_type'] = 'config'; 

to

$cfg['Servers'][$i]['auth_type'] = 'cookie'; 

then you will be prompted to login when you refreshed the page. Afterwards, the log out icon will appear next to home icon.

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

You can use:

GLfloat coordinates[8] = {1.0f, ..., 0.0f};

but this is a compile-time initialisation - you can't use that method in the current standard to re-initialise (although I think there are ways to do it in the upcoming standard, which may not immediately help you).

The other two ways that spring to mind are to blat the contents if they're fixed:

GLfloat base_coordinates[8] = {1.0f, ..., 0.0f};
GLfloat coordinates[8];
:
memcpy (coordinates, base_coordinates, sizeof (coordinates));

or provide a function that looks like your initialisation code anyway:

void setCoords (float *p0, float p1, ..., float p8) {
    p0[0] = p1; p0[1] = p2; p0[2] = p3; p0[3] = p4;
    p0[4] = p5; p0[5] = p6; p0[6] = p7; p0[7] = p8;
}
:
setCoords (coordinates, 1.0f, ..., 0.0f);

keeping in mind those ellipses (...) are placeholders, not things to literally insert in the code.

If you have the month number, you can first create a date from it with a default date of 1st and default year of the current year, then extract the month name from the date created:

echo date("F", strtotime(date("Y") ."-". $i ."-01"))

This code assumes you have your month number stored in $i

for(int index = 0; index < ((ViewGroup) viewGroup).getChildCount(); index++) {
    View nextChild = ((ViewGroup) viewGroup).getChildAt(index);
}

Will that do?

Add the following to your pom.xml and take out the dependency from asm jars from hibernate and add separate dependency to asm in a separate section. I did the same and it worked in one shot.

    <!-- Hibernate core -->

BalusC gave a good description about the problem but it lacks a good end to end code that users can pick and test it for themselves.

Best practice is to always store date-time in UTC timezone in DB. Sql timestamp type does not have timezone info.

When writing datetime value to sql db

    //Convert the time into UTC and build Timestamp object.
    Timestamp ts = Timestamp.valueOf(LocalDateTime.now(ZoneId.of("UTC")));
    //use setTimestamp on preparedstatement
    preparedStatement.setTimestamp(1, ts);

When reading the value back from DB into java,

1. Read it as it is in java.sql.Timestamp type.
2. Decorate the DateTime value as time in UTC timezone using atZone method in LocalDateTime class.

3. Then, change it to your desired timezone. Here I am changing it to Toronto timezone.

   ResultSet resultSet = preparedStatement.executeQuery();
   resultSet.next();
   Timestamp timestamp = resultSet.getTimestamp(1);
   ZonedDateTime timeInUTC = timestamp.toLocalDateTime().atZone(ZoneId.of("UTC"));
   LocalDateTime timeInToronto = LocalDateTime.ofInstant(timeInUTC.toInstant(), ZoneId.of("America/Toronto"));
   

In this problem, the answer is not updated in a timely. So it's happy to say that in 2020 Migrating to MsSQL into MySQL is that much easy. An online converter like RebaseData will do your job with one click. You can just upload your .bak file which is from MsSQL and convert it into .sql format which is readable to MySQL.

Additional note: This can not only convert your .bak files but also this site is for all types of Database migrations that you want.

When it is matter of mysql how to count or get how many rows in a table with PHP PDO I use this

// count total number of rows
$query = "SELECT COUNT(*) as total_rows FROM sometable";
$stmt = $con->prepare($query);

// execute query
$stmt->execute();

// get total rows
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$total_rows = $row['total_rows'];

If you want to copy the DataTable to another DataTable of different Schema Structure then you can do this:

• Firstly Clone the first DataType so that you can only get the structure.
• Then alter the newly created structure as per your need and then copy the data to newly created DataTable .

So:

Dim dt1 As New DataTable
dt1 = dtExcelData.Clone()
dt1.Columns(17).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(26).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(30).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(35).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(38).DataType = System.Type.GetType("System.Decimal")
dt1 = dtprevious.Copy()

Hence you get the same DataTable but revised structure

If the table is compressed this will work:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES move nocompress;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

alter table EVAPP_FEES compress;

I'm not sure if it's the same in Java, but enum types in C are automatically mapped to integers as well so you can use either the type or integer to access it. Have you tried simply accessing it with integer yet?

Did the error also report that it was missing an application name? I had this issue until I created a project name (e.g. "Project X") in the project settings dialog.

It's definitely an issue with some of the projects being built for x86 compatibility instead of any CPU. If I had to guess I would say that some of the references between your projects are probably referencing the dll's in some of the bin\debug folders instead of being project references.

When a project is compiled for x86 instead of 'Any CPU' the dll's go into the bin\x86\debug folder instead of bin\debug (which is probably where your references are looking).

But in any case, you should be using project references between your projects.

Get UltraMon. Quickly.

http://realtimesoft.com/ultramon/

It doesn't let you specify what monitor an app starts on, but it lets you move an app to the another monitor, and keep its aspect ratio intact, with one mouse click. It is a very handy utility.

Most programs will start where you last left them. So if you have two monitors at work, but only one at home, it's possible to start you laptop at home and not see the apps running on the other monitor (which now isn't there). UltrMon also lets you move those orphan apps back to the main screen quickly and easily.

str.split() without any arguments splits on runs of whitespace characters:

>>> s = 'I am having a very nice day.'
>>> 
>>> len(s.split())
7

From the linked documentation:

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.

Strictly with sed:

I had this problem and I solved with this way:

fieldset.scheduler-border {
    border: solid 1px #DDD !important;
    padding: 0 10px 10px 10px;
    border-bottom: none;
}

legend.scheduler-border {
    width: auto !important;
    border: none;
    font-size: 14px;
}

I'm used "for" operator.

try
{
    string s = textBox2.Text;
    string[] f = s.Split(',');

    for (int i = 0; i < f.Length; i++)
    {
        MailMessage message = new MailMessage(); // Create instance of message
        message.To.Add(f[i]); // Add receiver
        message.From = new System.Net.Mail.MailAddress(c);// Set sender .In this case the same as the username
        message.Subject = label3.Text; // Set subject
        message.Body = richTextBox1.Text; // Set body of message
        client.Send(message); // Send the message
        message = null; // Clean up
    }

}

catch (Exception ex)
{

    MessageBox.Show(ex.Message);

This is very simple if you are not using SQLite:

You can delete the SQLite DLLs from your solution's bin folders, then from the folder where you reference ELMAH. Rebuild, and your app won't try to load this DLL that you are not using.

To select the ith row, use iloc:

In [31]: df_test.iloc[0]
Out[31]: 
ATime     1.2
X         2.0
Y        15.0
Z         2.0
Btime     1.2
C        12.0
D        25.0
E        12.0
Name: 0, dtype: float64

To select the ith value in the Btime column you could use:

In [30]: df_test['Btime'].iloc[0]
Out[30]: 1.2

There is a difference between df_test['Btime'].iloc[0] (recommended) and df_test.iloc[0]['Btime']:

DataFrames store data in column-based blocks (where each block has a single dtype). If you select by column first, a view can be returned (which is quicker than returning a copy) and the original dtype is preserved. In contrast, if you select by row first, and if the DataFrame has columns of different dtypes, then Pandas copies the data into a new Series of object dtype. So selecting columns is a bit faster than selecting rows. Thus, although df_test.iloc[0]['Btime'] works, df_test['Btime'].iloc[0] is a little bit more efficient.

There is a big difference between the two when it comes to assignment. df_test['Btime'].iloc[0] = x affects df_test, but df_test.iloc[0]['Btime'] may not. See below for an explanation of why. Because a subtle difference in the order of indexing makes a big difference in behavior, it is better to use single indexing assignment:

df.iloc[0, df.columns.get_loc('Btime')] = x

df.iloc[0, df.columns.get_loc('Btime')] = x (recommended):

The recommended way to assign new values to a DataFrame is to avoid chained indexing, and instead use the method shown by andrew,

df.loc[df.index[n], 'Btime'] = x

or

df.iloc[n, df.columns.get_loc('Btime')] = x

The latter method is a bit faster, because df.loc has to convert the row and column labels to positional indices, so there is a little less conversion necessary if you use df.iloc instead.

df['Btime'].iloc[0] = x works, but is not recommended:

Although this works, it is taking advantage of the way DataFrames are currently implemented. There is no guarantee that Pandas has to work this way in the future. In particular, it is taking advantage of the fact that (currently) df['Btime'] always returns a view (not a copy) so df['Btime'].iloc[n] = x can be used to assign a new value at the nth location of the Btime column of df.

Since Pandas makes no explicit guarantees about when indexers return a view versus a copy, assignments that use chained indexing generally always raise a SettingWithCopyWarning even though in this case the assignment succeeds in modifying df:

In [22]: df = pd.DataFrame({'foo':list('ABC')}, index=[0,2,1])
In [24]: df['bar'] = 100
In [25]: df['bar'].iloc[0] = 99
/home/unutbu/data/binky/bin/ipython:1: SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

See the caveats in the documentation: http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy
  self._setitem_with_indexer(indexer, value)

In [26]: df
Out[26]: 
  foo  bar
0   A   99  <-- assignment succeeded
2   B  100
1   C  100

df.iloc[0]['Btime'] = x does not work:

In contrast, assignment with df.iloc[0]['bar'] = 123 does not work because df.iloc[0] is returning a copy:

In [66]: df.iloc[0]['bar'] = 123
/home/unutbu/data/binky/bin/ipython:1: SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

See the caveats in the documentation: http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy

In [67]: df
Out[67]: 
  foo  bar
0   A   99  <-- assignment failed
2   B  100
1   C  100

Warning: I had previously suggested df_test.ix[i, 'Btime']. But this is not guaranteed to give you the ith value since ix tries to index by label before trying to index by position. So if the DataFrame has an integer index which is not in sorted order starting at 0, then using ix[i] will return the row labeled i rather than the ith row. For example,

In [1]: df = pd.DataFrame({'foo':list('ABC')}, index=[0,2,1])

In [2]: df
Out[2]: 
  foo
0   A
2   B
1   C

In [4]: df.ix[1, 'foo']
Out[4]: 'C'

Try

<p>Click on <img src="/storage/help/button2.1.png" width="auto"

It works for me

Source location should be the URL (relative to the css file or full web location), not a file system full path, for example:

background: url("http://localhost/media/css/static/img/sprites/buttons-v3-10.png");
background: url("static/img/sprites/buttons-v3-10.png");

Alternatively, you can try to use file:/// protocol prefix.

Here's a good class :

public class Palindrome {

  public static boolean isPalindrome(String stringToTest) {
    String workingCopy = removeJunk(stringToTest);
    String reversedCopy = reverse(workingCopy);

    return reversedCopy.equalsIgnoreCase(workingCopy);
  }

  protected static String removeJunk(String string) {
    int i, len = string.length();
    StringBuffer dest = new StringBuffer(len);
    char c;

    for (i = (len - 1); i >= 0; i--) {
      c = string.charAt(i);
      if (Character.isLetterOrDigit(c)) {
        dest.append(c);
      }
    }

    return dest.toString();
  }

  protected static String reverse(String string) {
    StringBuffer sb = new StringBuffer(string);

    return sb.reverse().toString();
  }

  public static void main(String[] args) {
    String string = "Madam, I'm Adam.";

    System.out.println();
    System.out.println("Testing whether the following "
        + "string is a palindrome:");
    System.out.println("    " + string);
    System.out.println();

    if (isPalindrome(string)) {
      System.out.println("It IS a palindrome!");
    } else {
      System.out.println("It is NOT a palindrome!");
    }
    System.out.println();
  }
}

Enjoy.

You should check out Losswise (https://losswise.com), it has a plugin for Keras that's easier to use than Tensorboard and has some nice extra features. With Losswise you'd just use from losswise.libs import LosswiseKerasCallback and then callback = LosswiseKerasCallback(tag='my fancy convnet 1') and you're good to go (see https://docs.losswise.com/#keras-plugin).

if you want to find about object name e.g. table name and stored procedure on which particular user has permission, use the following query:

SELECT pr.principal_id, pr.name, pr.type_desc, 
    pr.authentication_type_desc, pe.state_desc, pe.permission_name, OBJECT_NAME(major_id) objectName
FROM sys.database_principals AS pr
JOIN sys.database_permissions AS pe ON pe.grantee_principal_id = pr.principal_id
--INNER JOIN sys.schemas AS s ON s.principal_id =  sys.database_role_members.role_principal_id 
     where pr.name in ('youruser1','youruser2') 

Yes: replace_all is one of the boost string algorithms:

Although it's not a standard library, it has a few things on the standard library:

1. More natural notation based on ranges rather than iterator pairs. This is nice because you can nest string manipulations (e.g., replace_all nested inside a trim). That's a bit more involved for the standard library functions.
2. Completeness. This isn't hard to be 'better' at; the standard library is fairly spartan. For example, the boost string algorithms give you explicit control over how string manipulations are performed (i.e., in place or through a copy).

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

An initial keyword is being added in CSS3 to allow authors to explicitly specify this initial value.

To sum up:

What do you actually want to achieve? What your code does is it tries to connect to a server located at 192.168.1.104:4000. Is this the address of a server that sends the messages (because this looks like a client-side code)? If I run fake server locally:

$ nc -l 4000

...and change socket address to localhost:4000, it will work and try to read something from nc-created server.

What you probably want is to create a ServerSocket and listen on it:

ServerSocket serverSocket = new ServerSocket(4000);
Socket socket = serverSocket.accept();

The second line will block until some other piece of software connects to your machine on port 4000. Then you can read from the returned socket. Look at this tutorial, this is actually a very broad topic (threading, protocols...)

These days something like the following will suffice:

HttpHeaders headers = new HttpHeaders();
headers.setBearerAuth(accessToken);
restTemplate.exchange(RequestEntity.get(new URI(url)).headers(headers).build(), returnType);

In Windows 7 Path Environment Variables I just add at the end of System Variable path

\;C:\Program Files\Git\bin

and it works now!

This worked much better in my case.

Use

$(foo)
EOF

You can trick read into accepting from a pipe like this:

echo "hello world" | { read test; echo test=$test; }

or even write a function like this:

read_from_pipe() { read "$@" <&0; }

But there's no point - your variable assignments may not last! A pipeline may spawn a subshell, where the environment is inherited by value, not by reference. This is why read doesn't bother with input from a pipe - it's undefined.

FYI, http://www.etalabs.net/sh_tricks.html is a nifty collection of the cruft necessary to fight the oddities and incompatibilities of bourne shells, sh.

1. Select columns A:H with A1 as the active cell.
2. Open Home ? Styles ? Conditional Formatting ? New Rule.
3. Choose Use a formula to determine which cells to format and supply one of the following formulas¹ in the Format values where this formula is true: text box.
   • To highlight the Account and Store Manager columns when one of the four dates is blank:
             =AND(LEN($A1), COLUMN()<3, COUNTBLANK($E1:$H1))
   • To highlight the Account, Store Manager and blank date columns when one of the four dates is blank:
             =AND(LEN($A1), OR(COLUMN()<3, AND(COLUMN()>4, COUNTBLANK(A1))), COUNTBLANK($E1:$H1))
4. Click [Format] and select a cell Fill.
5. Click [OK] to accept the formatting and then [OK] again to create the new rule. In both cases, the Applies to: will refer to =$A:$H.

Results should be similar to the following.

¹ _{The COUNTBLANK function was introduced with Excel 2007. It will count both true blanks and zero-length strings left by formulas (e.g. "").}

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

But the thing is that the .chapter class is not dynamic you're declaring a height:1200px

so it's better to use background:cover and set with media queries specific height's for popular resolutions.

Use subprocess.Popen:

import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)

Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.

You can check if your string starts with http or https using the small function below.

function has_prefix($string, $prefix) {
   return substr($string, 0, strlen($prefix)) == $prefix;
}

$url   = 'http://www.google.com';
echo 'the url ' . (has_prefix($url, 'http://')  ? 'does' : 'does not') . ' start with http://';
echo 'the url ' . (has_prefix($url, 'https://') ? 'does' : 'does not') . ' start with https://';

// GET: api/GetStudent

public Response Get() {
    return StoredProcedure.GetStudent();
}

public static Response GetStudent() {
    using (var db = new dal()) {
        var student = db.Database.SqlQuery<GetStudentVm>("GetStudent").ToList();
        return new Response {
            Sucess = true,
            Message = student.Count() + " Student found",
            Data = student
        };
    }
}

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

Reference blog 'story'

I used $form.submit() as it keeps html input validation.

Also I used input type tel as it supported by mobile browsers, only display numeric keypad.

<input type="tel" minlength="10" maxlength="10" id="mobile" name="mobile" title="10 digit mobile number" required>


$('#mob_frm').submit(function(e) {
            e.preventDefault();
            if(!$('#mobile').val().match('[0-9]{10}'))  {
                alert("Please put 10 digit mobile number");
                return;
            }  

        });

You are trying to play a .mp3 as if it were a .wav.

You could try using pydub to convert it to .wav format, and then feed that into pyAudio.

Example:

from pydub import AudioSegment

song = AudioSegment.from_mp3("original.mp3")
song.export("final.wav", format="wav")

Alternatively, use pygame, as mentioned in the other answer.

You can use the spool command (SQL*Plus documentation, but one of many such commands SQL Developer also supports) to write results straight to disk. Each spool can change the file that's being written to, so you can have several queries writing to different files just by putting spool commands between them:

spool "\path\to\spool1.txt"

select /*csv*/ * from employees;

spool "\path\to\spool2.txt"

select /*csv*/ * from locations;

spool off;

You'd need to run this as a script (F5, or the second button on the command bar above the SQL Worksheet). You might also want to explore some of the formatting options and the set command, though some of those do not translate to SQL Developer.

Since you mentioned CSV in the title I've included a SQL Developer-specific hint that does that formatting for you.

A downside though is that SQL Developer includes the query in the spool file, which you can avoid by having the commands and queries in a script file that you then run as a script.

We have to set theme before calling 'super.onCreate()' and 'setContentView()' method.

Check out this link for applying new theme to whole application at runtime.

The Python library pdf2image (used in the other answer) in fact doesn't do much more than just launching pdttoppm with subprocess.Popen, so here is a short version doing it directly:

PDFTOPPMPATH = r"D:\Documents\software\____PORTABLE\poppler-0.51\bin\pdftoppm.exe"
PDFFILE = "SKM_28718052212190.pdf"

import subprocess
subprocess.Popen('"%s" -png "%s" out' % (PDFTOPPMPATH, PDFFILE))

Here is the Windows installation link for pdftoppm (contained in a package named poppler): http://blog.alivate.com.au/poppler-windows/

The solution by Ben Blank wouldn't work in IE8 for me.

However this did work in IE8

function addCss(cssCode) {
var styleElement = document.createElement("style");
  styleElement.type = "text/css";
  if (styleElement.styleSheet) {
    styleElement.styleSheet.cssText = cssCode;
  } else {
    styleElement.appendChild(document.createTextNode(cssCode));
  }
  document.getElementsByTagName("head")[0].appendChild(styleElement);
}

ExecuteScalar will return

• null if there is no result set
• otherwise the first column of the first row of the resultset, which may be DBNull.

If you know that the first column of the resultset is a string, then to cover all bases you need to check for both null and DBNull. Something like:

object accountNumber = ...ExecuteScalar(...);
return (accountNumber == null) ? String.Empty : accountNumber.ToString();

The above code relies on the fact that DBNull.ToString returns an empty string.

If accountNumber was another type (say integer), then you'd need to be more explicit:

object accountNumber = ...ExecuteScalar(...);
return (accountNumber == null || Convert.IsDBNull(accountNumber) ?     
         (int) accountNumber : 0;

If you know for sure that your resultset will always have at least one row (e.g. SELECT COUNT(*)...), then you can skip the check for null.

In your case the error message "Unable to cast object of type ‘System.DBNull’ to type ‘System.String`" indicates that the first column of your result set is a DBNUll value. This is from the cast to string on the first line:

string accountNumber = (string) ... ExecuteScalar(...);

Marc_s's comment that you don't need to check for DBNull.Value is wrong.
