If you are targeting Windows XP (v140_xp), try installing Windows XP Support for C++.

Starting with Visual Studio 2012, the default toolset (v110) dropped support for Windows XP. As a result, a Windows.h error can occur if your project is targeting Windows XP with the default C++ packages.

Check which Windows SDK version is specified in your project's Platform Toolset. (Project ? Properties ? Configuration Properties ? General). If your Toolset ends in _xp, you'll need to install XP support.

Open the Visual Studio Installer and click Modify for your version of Visual Studio. Open the Individual Components tab and scroll down to Compilers, build tools, and runtimes. Near the bottom, check Windows XP support for C++ and click Modify to begin installing.

for making uppercase from lowercase to upper just use

"string".upper()

where "string" is your string that you want to convert uppercase

for this question concern it will like this:

s.upper()

for making lowercase from uppercase string just use

"string".lower()

where "string" is your string that you want to convert lowercase

for this question concern it will like this:

s.lower()

If you want to make your whole string variable use

s="sadf"
# sadf

s=s.upper()
# SADF

What did the trick for me was to update CYGWIN environment variable with: "tty nodosfilewarning". Didn't even need to chmod the key.

The output file needs to be opened in binary mode:

f = open('varstor.txt','w')

needs to be:

f = open('varstor.txt','wb')

Use parentheses to group the individual branches:

IF EXIST D:\RPS_BACKUP\backups_to_zip\ (goto zipexist) else goto zipexistcontinue

In your case the parser won't ever see the else belonging to the if because goto will happily accept everything up to the end of the command. You can see a similar issue when using echo instead of goto.

Also using parentheses will allow you to use the statements directly without having to jump around (although I wasn't able to rewrite your code to actually use structured programming techniques; maybe it's too early or it doesn't lend itself well to block structures as the code is right now).

The gist is that the foreign method uses ALTER_TABLE to make a pre-existing field into a foreign key. So you have to define the table type before you apply the foreign key. However, it doesn't have to be in a separate Schema:: call. You can do both within create, like this:

public function up()
{
    Schema::create('priorities', function($table) {
        $table->increments('id', true);
        $table->integer('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->string('priority_name');
        $table->smallInteger('rank');
        $table->text('class');
        $table->timestamps('timecreated');
    });
}

Also note that the type of user_id is set to unsigned to match the foreign key.

Just download and install "Samsung Kies" from this link. and everything would work as required.

Before installing, uninstall the drivers you have installed for your device.

Update:

Two possible solutions:

1. Try with the Google USB driver which comes with the SDK.
2. Download and install the Samsung USB driver from this link as suggested by Mauricio Gracia Gutierrez

Well, to all who actually can't find the error anywhere in your code, neither "undefined as it says in local storage nor null"..simply just comment out your code and write another one that actually removes the item in local storage ..after that ,u can comment or delet the current code and reset again the previous one by simply uncommenting it out (if u dint delet t ...if u did u can write it again:))

LocalStorage.setItem('Previous' , "removeprevious");  


LocalStorage.removeItem('Previous');   
 Console.log(LocalStorage.getItem('Previous'));

Console will show null and that it ..reset your code again if t doesn't work, dude!you got errors.

sorry for my English!

I think who the best mix for html & Css for quick and clean mod is :

<table class="table text-center">

        <tr>                    
        <th class="text-center">Uno</th>
        <th class="text-center">Due</th>
        <th class="text-center">Tre</th>
        <th class="text-center">Quattro</th>
    </tr>
</thead>
<tbody>
    <tr>

        <td>2</td>
        <td>3</td>
        <td>4</td>
    </tr>
</tbody>
</table>

close the <table> init tag then copy where you want :) I hope it can be useful Have a good day w stackoverflow

All previous examples will raise an exception in case your string is not long enough.

Another approach is to use 'yourstring'.ljust(100)[:100].strip().

This will give you first 100 chars. You might get a shorter string in case your string last chars are spaces.

This error is also thrown when your User does not have the expected Role delegated in User definition(Set role for the Realm in drop down).

Here is the code you need:

start cmd.exe @cmd /k "Command"

I wrote a little query to find permission of a user on a specific database.

    SELECT * FROM   
    (
    SELECT 
    perm.permission_name AS 'PERMISSION'
    ,perm.state_desc AS 'RIGHT'
    ,perm.class_desc AS 'RIGHT_ON'
    ,p.NAME AS 'GRANTEE'
    ,m.NAME AS 'USERNAME'
    ,s.name AS 'SCHEMA'
    ,o.name AS 'OBJECT'
    ,IIF(perm.class = 0, db_name(), NULL) AS 'DATABASE'
    FROM
    sys.database_permissions perm
    INNER JOIN sys.database_principals p ON p.principal_id = perm.grantee_principal_id
    LEFT JOIN sys.database_role_members rm ON rm.role_principal_id = p.principal_id
    LEFT JOIN sys.database_principals m ON rm.member_principal_id = m.principal_id
    LEFT JOIN sys.schemas s ON perm.class = 3 AND perm.major_id = s.schema_id
    LEFT JOIN sys.objects AS o ON perm.class = 1 AND perm.major_id = o.object_id
    UNION ALL
    SELECT 
    perm.permission_name AS 'PERMISSION'
    ,perm.state_desc AS 'RIGHT'
    ,perm.class_desc AS 'RIGHT_ON'
    ,'SELF-GRANTED' AS 'GRANTEE'
    ,p.NAME AS 'USERNAME'
    ,s.name AS 'SCHEMA'
    ,o.name AS 'OBJECT'
    ,IIF(perm.class = 0, db_name(), NULL) AS 'DATABASE'
    FROM
    sys.database_permissions perm
    INNER JOIN sys.database_principals p ON p.principal_id = perm.grantee_principal_id
    LEFT JOIN sys.schemas s ON perm.class = 3 AND perm.major_id = s.schema_id
    LEFT JOIN sys.objects AS o ON perm.class = 1 AND perm.major_id = o.object_id
    ) AS [union]
    WHERE [union].USERNAME = 'Username' -- Username you will search for
    ORDER BY [union].RIGHT_ON, [union].PERMISSION, [union].GRANTEE

The permissions of fixed database roles do not appear in sys.database_permissions. Therefore, database principals may have additional permissions not listed here.

I does not prefer

    EXECUTE AS USER = 'userName';
    SELECT * FROM fn_my_permissions(NULL, 'DATABASE') 

Because it's just retrieving which permissions the user has not where they come from!

Maybe i find out how to join the fixed database roles permission granted for the user one day...

Pls enjoy Life and hate the Users :D

I faced a similar situation:

I was trying to read raw response in case of an HTTP error consuming a SOAP service, using BasicHTTPBinding.

However, when reading the response using GetResponseStream(), got the error:

Stream not readable

So, this code worked for me:

try
{
    response = basicHTTPBindingClient.CallOperation(request);
}
catch (ProtocolException exception)
{
    var webException = exception.InnerException as WebException;
    var rawResponse = string.Empty;

    var alreadyClosedStream = webException.Response.GetResponseStream() as MemoryStream;
    using (var brandNewStream = new MemoryStream(alreadyClosedStream.ToArray()))
    using (var reader = new StreamReader(brandNewStream))
        rawResponse = reader.ReadToEnd();
}

$mylabel.text( $mylabel.text().replace('-', '') );

Since text() gets the value, and text( "someValue" ) sets the value, you just place one inside the other.

Would be the equivalent of doing:

var newValue = $mylabel.text().replace('-', '');
$mylabel.text( newValue );

EDIT:

I hope I understood the question correctly. I'm assuming $mylabel is referencing a DOM element in a jQuery object, and the string is in the content of the element.

If the string is in some other variable not part of the DOM, then you would likely want to call the .replace() function against that variable before you insert it into the DOM.

Like this:

var someVariable = "-123456";
$mylabel.text( someVariable.replace('-', '') );

or a more verbose version:

var someVariable = "-123456";
someVariable = someVariable.replace('-', '');
$mylabel.text( someVariable );

I had to add packaging, so:

mvn install:install-file \
  -DgroupId=javax.transaction \
  -DartifactId=jta \
  -Dversion=1.0.1B \
  -Dfile=jta-1.0.1B.jar \
  -DgeneratePom=true \
  -Dpackaging=jar

Try using Async instead to avoid blocking the only thread you have with NodeJS. Check this example:

const util = require('util');
const fs = require('fs');
const path = require('path');
const readFileAsync = util.promisify(fs.readFile);

const readContentFile = async (filePath) => {
  // Eureka, you are using good code practices here!
  const content = await readFileAsync(path.join(__dirname, filePath), {
    encoding: 'utf8'
  })
  return content;
}

Later can use this async function with try/catch from any other function:

const anyOtherFun = async () => {
  try {
    const fileContent = await readContentFile('my-file.txt');
  } catch (err) {
    // Here you get the error when the file was not found,
    // but you also get any other error
  }
}

Happy Coding!

This process is somewhat un-orthodox, but would work across all python versions,

Suppose you want to execute a script named 'recommend.py' inside an 'if' condition, then use,

if condition:
       import recommend

The technique is different, but works!

I tried a few options, which were incredibly slow. This split a 360GB dump into its tables in a few minutes:

How do I split the output from mysqldump into smaller files?

Assumed you have data frame as below

df1
     A    B    C    D
4 -1.0 -1.0 -1.0 -1.0
5 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0

When you would like create another df2 which is identical to df1, without copy

df2=df1
df2
     A    B    C    D
4 -1.0 -1.0 -1.0 -1.0
5 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0

And would like modify the df2 value only as below

df2.iloc[0,0]='changed'

df2
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

At the same time the df1 is changed as well

df1
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

Since two df as same object, we can check it by using the id

id(df1)
140367679979600
id(df2)
140367679979600

So they as same object and one change another one will pass the same value as well.

If we add the copy, and now df1 and df2 are considered as different object, if we do the same change to one of them the other will not change.

df2=df1.copy()
id(df1)
140367679979600
id(df2)
140367674641232

df1.iloc[0,0]='changedback'
df2
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

Good to mention, when you subset the original dataframe, it is safe to add the copy as well in order to avoid the SettingWithCopyWarning

 override func viewDidLoad() {

    super.viewDidLoad()       
    locationManager.requestWhenInUseAuthorization();     
    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.startUpdatingLocation()
    }
    else{
        print("Location service disabled");
    }
  }

This is your view did load method and in the ViewController Class also include the mapStart updating method as follows

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var locValue : CLLocationCoordinate2D = manager.location.coordinate;
    let span2 = MKCoordinateSpanMake(1, 1)    
    let long = locValue.longitude;
    let lat = locValue.latitude;
    print(long);
    print(lat);        
    let loadlocation = CLLocationCoordinate2D(
                    latitude: lat, longitude: long            

   )     

    mapView.centerCoordinate = loadlocation;
    locationManager.stopUpdatingLocation();
}

Also do not forget to add CoreLocation.FrameWork and MapKit.Framework in your project (no longer necessary as of XCode 7.2.1)

Here is how you do it:

$http.get("/url/to/resource/", {params:{"param1": val1, "param2": val2}})
    .then(function (response) { /* */ })...

Angular takes care of encoding the parameters.

Maxim Shoustin's answer does not work ({method:'GET', url:'/search', jsonData} is not a valid JavaScript literal) and JeyTheva's answer, although simple, is dangerous as it allows XSS (unsafe values are not escaped when you concatenate them).

There are significant differences. Let's set up some test cases:

var unused; // value will be undefined
Test("test1", "some value");
Test("test2");
Test("test3", unused);
Test("test4", null);
Test("test5", 0);
Test("test6", "");

With the first method you describe, only the second test will use the default value. The second method will default all but the first (as JS will convert undefined, null, 0, and "" into the boolean false. And if you were to use Tom's method, only the fourth test will use the default!

Which method you choose really depends on your intended behavior. If values other than undefined are allowable for argument2, then you'll probably want some variation on the first; if a non-zero, non-null, non-empty value is desired, then the second method is ideal - indeed, it is often used to quickly eliminate such a wide range of values from consideration.

I am reading the Pro ASP.NET MVC 4 book as well, and ran into the same problem you were having. For me, I started having the problem after making the changes prescribed in the 'Adding Model Validation' section of the book. The way I resolved the problem is by moving my database from the localdb to the full-blown SQL Server 2012 server. (BTW, I know that I am lucky I could switch to the full-blown version, so don't hate me. ;-))) There must be something with the communication to the db that is causing the problem.

I think the previous answers are correct, but here is another example (just a f.y.i, success() and error() are deprecated according to AngularJS Main page:

$http
    .get('http://someendpoint/maybe/returns/JSON')
    .then(function(response) {
        return response.data;
    }).catch(function(e) {
        console.log('Error: ', e);
        throw e;
    }).finally(function() {
        console.log('This finally block');
    });

Servlets :

The Java Servlet API enables Java developers to write server-side code for delivering dynamic Web content. Like other proprietary Web server APIs, the Java Servlet API offered improved performance over CGI; however, it has some key additional advantages. Because servlets were coded in Java, they provides an object-oriented (OO) design approach and, more important, are able to run on any platform. Thus, the same code was portable to any host that supported Java. Servlets greatly contributed to the popularity of Java, as it became a widely used technology for server-side Web application development.

JSP :

JSP is built on top of servlets and provides a simpler, page-based solution to generating large amounts of dynamic HTML content for Web user interfaces. JavaServer Pages enables Web developers and designers to simply edit HTML pages with special tags for the dynamic, Java portions. JavaServer Pages works by having a special servlet known as a JSP container, which is installed on a Web server and handles all JSP page view requests. The JSP container translates a requested JSP into servlet code that is then compiled and immediately executed. Subsequent requests to the same page simply invoke the runtime servlet for the page. If a change is made to the JSP on the server, a request to view it triggers another translation, compilation, and restart of the runtime servlet.

JSF :

JavaServer Faces is a standard Java framework for building user interfaces for Web applications. Most important, it simplifies the development of the user interface, which is often one of the more difficult and tedious parts of Web application development.
Although it is possible to build user interfaces by using foundational Java Web technologies(such as Java servlets and JavaServer Pages) without a comprehensive framework designedfor enterprise Web application development, these core technologies can often lead to avariety of development and maintenance problems. More important, by the time the developers achieve a production-quality solution, the same set of problems solved by JSF will have been solved in a nonstandard manner. JavaServer Faces is designed to simplify the development of user interfaces for Java Web applications in the following ways:
• It provides a component-centric, client-independent development approach to building Web user interfaces, thus improving developer productivity and ease of use.
• It simplifies the access and management of application data from the Web user interface.
• It automatically manages the user interface state between multiple requests and multiple clients in a simple and unobtrusive manner.
• It supplies a development framework that is friendly to a diverse developer audience with different skill sets.
• It describes a standard set of architectural patterns for a web application.

Let's see both the options:

1.) Use PHP inside Javascript

<script>
    <?php $temp = 'hello';?>
    console.log('<?php echo $temp; ?>');

Note: File name should be in .php only.

2.) Use Javascript variable inside PHP

<script>
  var res = "success";
</script>
<?php
   echo "<script>document.writeln(res);</script>";

Today I filed a JEP draft to OpenJDK about this aliasing feature. I hope they will reconsider it.

If you want numbers to be uniformly distributed over the range, you should break your range up into a number of equal sections that represent the number of points you need. Then get a random number with a min/max for each section.

As another note, you should probably not use rand() as it's not very good at actually generating random numbers. I don't know what platform you're running on, but there is probably a better function you can call like random().

select * 
from sysobjects 
where xtype='pk' and 
   parent_obj in (select id from sysobjects where name='tablename')

this will work in sql 2005

Of course you can, in the sense that your RDBMS will let you do it. The answer to a question of whether or not you should do it is different, though: in most situations, values that have a meaning outside your database system should not be chosen to be a primary key.

If you know that the value is unique in the system that you are modeling, it is appropriate to add a unique index or a unique constraint to your table. However, your primary key should generally be some "meaningless" value, such as an auto-incremented number or a GUID.

The rationale for this is simple: data entry errors and infrequent changes to things that appear non-changeable do happen. They become much harder to fix on values which are used as primary keys.

This function will convert a UTC time to EST time with DST adjustment. You can change your designed time zone name in this function, or get it from registry:

Create Function fnConvertUTCTimetoESTTime(
    @UTCTime as datetime
)
returns datetime
as
begin
    return convert(datetime, convert(varchar(23), @UTCTime AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time', 121), 121)
end
go

select dbo.fnConvertUTCTimetoESTTime ('2020-3-8 5:00:00.000')
    , dbo.fnConvertUTCTimetoESTTime ('2020-3-8 6:00:00.000')
    , dbo.fnConvertUTCTimetoESTTime ('2020-3-8 7:00:00.000')
    , dbo.fnConvertUTCTimetoESTTime ('2020-3-8 8:00:00.000')

--returns 0:00am, 1:00am, 3:00am, 4:00am

select dbo.fnConvertUTCTimetoESTTime ('2020-11-1 4:00:00.000')
    , dbo.fnConvertUTCTimetoESTTime ('2020-11-1 5:00:00.000')
    , dbo.fnConvertUTCTimetoESTTime ('2020-11-1 6:00:00.000')
    , dbo.fnConvertUTCTimetoESTTime ('2020-11-1 7:00:00.000')

--returns 0:00am, 1:00am, 1:00am, 2:00am

Note you can not just return "@UTCTime AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time'" as the result because this result is actually a UTC time in EST format (when you compare this "fake" EST time or include it in an order clause it will be converted back to a UTC time).

History.

The earliest versions of Unix time had a 32-bit integer incrementing at a rate of 60 Hz, which was the rate of the system clock on the hardware of the early Unix systems. The value 60 Hz still appears in some software interfaces as a result. The epoch also differed from the current value. The first edition Unix Programmer's Manual dated November 3, 1971 defines the Unix time as "the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second".

I had the same issue and none of the other answers worked. It seems to occur frequently when you connect to the device using the wifi mode (running command 'adb tcpip 5555'). I found this solution, its sort of a workaround but it does work.

1. Disconnect the usb (or turn off devices wifi if your connected over wifi)
2. Close eclipse/other IDE
3. Check your running programs for adb.exe (Task manager in Windows). If its running, Terminate it.
4. Restart your android device
5. After your device restarts, connect it via USB and run 'adb devices'. This should start the adb daemon. And you should see your device online again.

This process is a little lengthy but its the only one that has worked everytime for me.

To read one byte:

file.read(1)

8 bits is one byte.

Lightsail VPSs are bundles of existing AWS products, offered through a significantly simplified interface. The difference is that Lightsail offers you a limited and fixed menu of options but with much greater ease of use. Other than the narrower scope of Lightsail in order to meet the requirements for simplicity and low cost, the underlying technology is the same.

The pre-defined bundles can be described:

% aws lightsail --region us-east-1 get-bundles
{
    "bundles": [
        {
            "name": "Nano",
            "power": 300,
            "price": 5.0,
            "ramSizeInGb": 0.5,
            "diskSizeInGb": 20,
            "transferPerMonthInGb": 1000,
            "cpuCount": 1,
            "instanceType": "t2.nano",
            "isActive": true,
            "bundleId": "nano_1_0"
        },
        ...
    ]
}

It's worth reading through the Amazon EC2 T2 Instances documentation, particularly the CPU Credits section which describes the base and burst performance characteristics of the underlying instances.

Importantly, since your Lightsail instances run in VPC, you still have access to the full spectrum of AWS services, e.g. S3, RDS, and so on, as you would from any EC2 instance.

Cleaner and more reusable approach is

define text size in dimens.xml file inside res/values/ directory:

</resources>
   <dimen name="text_medium">14sp</dimen>
</resources>

and then apply it to the TextView:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, context.getResources().getDimension(R.dimen.text_medium));

Why not you try REGEXP. Try it like this:

SELECT * FROM table WHERE interests REGEXP 'sports|pub'

For me the only working solution was to add the android-support-v7-appcompat library as well. It seems that this library is also needed in order to get rid of that message. Since then my applications have been working fine!

I hope it helps!

I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.

Like @Sunkas wrote, performSelector:withObject:afterDelay: is the pendant to the dispatch_after just that it is shorter and you have the normal objective-c syntax. If you need to pass arguments to the block you want to delay, you can just pass them through the parameter withObject and you will receive it in the selector you call:

[self performSelector:@selector(testStringMethod:) 
           withObject:@"Test Test" 
           afterDelay:0.5];

- (void)testStringMethod:(NSString *)string{
    NSLog(@"string  >>> %@", string);
}

If you still want to choose yourself if you execute it on the main thread or on the current thread, there are specific methods which allow you to specify this. Apples Documentation tells this:

If you want the message to be dequeued when the run loop is in a mode other than the default mode, use the performSelector:withObject:afterDelay:inModes: method instead. If you are not sure whether the current thread is the main thread, you can use the performSelectorOnMainThread:withObject:waitUntilDone: or performSelectorOnMainThread:withObject:waitUntilDone:modes: method to guarantee that your selector executes on the main thread. To cancel a queued message, use the cancelPreviousPerformRequestsWithTarget: or cancelPreviousPerformRequestsWithTarget:selector:object: method.

I have made a node module to read large file asynchronously text or JSON. Tested on large files.

var fs = require('fs')
, util = require('util')
, stream = require('stream')
, es = require('event-stream');

module.exports = FileReader;

function FileReader(){

}

FileReader.prototype.read = function(pathToFile, callback){
    var returnTxt = '';
    var s = fs.createReadStream(pathToFile)
    .pipe(es.split())
    .pipe(es.mapSync(function(line){

        // pause the readstream
        s.pause();

        //console.log('reading line: '+line);
        returnTxt += line;        

        // resume the readstream, possibly from a callback
        s.resume();
    })
    .on('error', function(){
        console.log('Error while reading file.');
    })
    .on('end', function(){
        console.log('Read entire file.');
        callback(returnTxt);
    })
);
};

FileReader.prototype.readJSON = function(pathToFile, callback){
    try{
        this.read(pathToFile, function(txt){callback(JSON.parse(txt));});
    }
    catch(err){
        throw new Error('json file is not valid! '+err.stack);
    }
};

Just save the file as file-reader.js, and use it like this:

var FileReader = require('./file-reader');
var fileReader = new FileReader();
fileReader.readJSON(__dirname + '/largeFile.json', function(jsonObj){/*callback logic here*/});

Here's a method using display:flex:

.container {_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  display: flex;_x000D_
  position: fixed;_x000D_
  align-items: center;_x000D_
  justify-content: center;_x000D_
}

<div class="container">_x000D_
  <div>centered text!</div>_x000D_
</div>

This is because your data sending column type is integer and your are sending a string value to it.

So, the following way worked for me. Try with this one.

$insertQuery = "INSERT INTO workorders VALUES (
                    null,
                    '$priority',
                    '$requestType',
                    '$purchaseOrder',
                    '$nte',
                    '$jobSiteNumber'
                )";

Don't use 'null'. use it as null without single quotes.

The idea is to send a callback to the child which will be called to give the data back

A complete and minimal example using functions:

App will create a Child which will compute a random number and send it back directly to the parent, which will console.log the result

const Child = ({ handleRandom }) => {
  handleRandom(Math.random())

  return <span>child</span>
}

const App = () => <Child handleRandom={(num) => console.log(num)}/>

1. Open Postman.
2. Enter URL in the URL bar http://{server:port}/json/metallica/post.
3. Click Headers button and enter Content-Type as header and application/json in value.
4. Select POST from the dropdown next to the URL text box.
5. Select raw from the buttons available below URL text box.
6. Select JSON from the following dropdown.

7. In the textarea available below, post your request object:

   {
    "title" : "test title",
    "singer" : "some singer"
   }
   

8. Hit Send.

9. Refer to screenshot below:

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

To find all including empty lines of code try @Neil's solution:

Open Find in Path (Ctrl+Shift+F)

Search for the following regular expression: \n'

For lines with at least one character use following expression:

(.+)\n

For lines with at least one word character or digit use following expression:

`(.*)([\w\d]+)(.*)\n`

Notice: But the last line of file is just counted if you have a line break after it.

This is a well-known issue and based on this answer you could add setLenient:

Gson gson = new GsonBuilder()
        .setLenient()
        .create();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .client(client)
        .addConverterFactory(GsonConverterFactory.create(gson))
        .build();

Now, if you add this to your retrofit, it gives you another error:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

This is another well-known error you can find answer here (this error means that your server response is not well-formatted); So change server response to return something:

{
    android:[
        { ver:"1.5", name:"Cupcace", api:"Api Level 3" }
        ...
    ]
}

For better comprehension, compare your response with Github api.

Suggestion: to find out what's going on to your request/response add HttpLoggingInterceptor in your retrofit.

Based on this answer your ServiceHelper would be:

private ServiceHelper() {
        httpClient = new OkHttpClient.Builder();
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        httpClient.interceptors().add(interceptor);
        Retrofit retrofit = createAdapter().build();
        service = retrofit.create(IService.class);
    }

Also don't forget to add:

compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'

Either in SQL or in report code (as per adolf garlic's function suggestion)

At this moment in time, I'd do it in the report. I have very few reports against a busy OLTP server and an underwhelmed report server. If I had a different mix I'd do it in SQL.

Either way is acceptable...

I had the same issue, and I can fix this with this solution:

select a.*, rownum 
from (select Fname from MyTbl order by Fname DESC) a
where
rownum = 1

You can order your result before to have the first value on top.

Good luck

OfType Linq method can be used exactly for this kind of scenarios:

https://docs.microsoft.com/fr-fr/dotnet/api/system.linq.enumerable.oftype?view=netframework-4.8

This worked for me in Eclipse Oxygen (4.7.0):

Right click Project -> Maven -> Select Maven Profiles... then check the Repository Proxy box, press OK.

By chance, is this occurring on a directory using OverlayFS (or some other special file system type)?

I just had this issue where my cross-compiled version of bash would use an internal implementation of getcwd which has issues with OverlayFS. I found information about this here:

It seems that this can be traced to an internal implementation of getcwd() in bash. When cross-compiled, it can't check for getcwd() use of malloc, so it is cautious and sets GETCWD_BROKEN and uses an internal implementation of getcwd(). This internal implementation doesn't seem to work well with OverlayFS.

http://permalink.gmane.org/gmane.linux.embedded.yocto.general/25204

You can configure and rebuild bash with bash_cv_getcwd_malloc=yes (if you're actually building bash and your C library does malloc a getcwd call).

...none of the other answers seem to do what the asker asked.

For table named 'things' with column 'group':

SELECT
  things.*, counter.count
FROM
  things
LEFT JOIN (
  SELECT
    things.group, count(things.group) as count
  FROM
    things
  GROUP BY
    things.group
) counter ON counter.group = things.group
ORDER BY
  counter.count ASC;

which gives:

id | name  | group | count 
---------------------------
3  | Cat   | B     | 1
1  | Apple | A     | 2
2  | Boy   | A     | 2

5  | Elep  | C     | 3
6  | Fish  | C     | 3

tl;dr

Duration.ofMinutes( 260L )
        .toString()

PT4H20M

… or …

LocalTime.MIN.plus( 
    Duration.ofMinutes( 260L ) 
).toString()

04:20

Duration

The java.time classes include a pair of classes to represent spans of time. The Duration class is for hours-minutes-seconds, and Period is for years-months-days.

Duration d = Duration.ofMinutes( 260L );

Duration parts

Access each part of the Duration by calling to…Part. These methods were added in Java 9 and later.

long days = d.toDaysPart() ;
int hours = d.toHoursPart() ;
int minutes = d.toMinutesPart() ;
int seconds = d.toSecondsPart() ;
int nanos = d.toNanosPart() ;

You can then assemble your own string from those parts.

ISO 8601

The ISO 8601 standard defines textual formats for date-time values. For spans of time unattached to the timeline, the standard format is PnYnMnDTnHnMnS. The P marks the beginning, and the T separates the years-month-days from the hours-minutes-seconds. So an hour and a half is PT1H30M.

The java.time classes use ISO 8601 formats by default for parsing and generating strings. The Duration and Period classes use this particular standard format. So simply call toString.

String output = d.toString(); 

PT4H20M

For alternate formatting, build your own String in Java 9 and later (not in Java 8) with the Duration::to…Part methods. Or see this Answer for using regex to manipulate the ISO 8601 formatted string.

LocalTime

I strongly suggest using the standard ISO 8601 format instead of the extremely ambiguous and confusing clock format of 04:20. But if you insist, you can get this effect by hacking with the LocalTime class. This works if your duration is not over 24 hours.

LocalTime hackUseOfClockAsDuration = LocalTime.MIN.plus( d );
String output = hackUseOfClockAsDuration.toString();

04:20

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

The pattern must have delimiters. Delimiters can be a forward slash (/) or any non alphanumeric characters(#,$,*,...). Examples

$pattern = "/My name is '(.*)' and im fine/"; 
$pattern = "#My name is '(.*)' and im fine#";
$pattern = "@My name is '(.*)' and im fine@";  

please chceck the type of file growth of the database, if its restricted make it unrestricted

Only use Popen kill method

process = subprocess.Popen(
    task.getExecutable(), 
    stdout=subprocess.PIPE, 
    stderr=subprocess.PIPE, 
    shell=True
)
process.kill()

To read messages you should use:

kafka-console-consumer.sh --bootstrap-server kafka1:9092,kafka2:9092,kafka3:9092 --topic messages --from-beginning

--bootstrap-server is required attribute. You can use only single kafka1:9020 node.

In case of NULL columns it is better to use IF clause like this which combine the two functions of : CONCAT and COALESCE and uses special chars between the columns in result like space or '_'

SELECT FirstName , LastName , 
IF(FirstName IS NULL AND LastName IS NULL, NULL,' _ ',CONCAT(COALESCE(FirstName ,''), COALESCE(LastName ,''))) 
AS Contact_Phone FROM   TABLE1

You could use SET ANSI_NULLS in order to specify the behavior of the Equals (=) and Not Equal To (<>) comparison operators when they are used with null values.

i faced this problem and solved it by using following codes. I was beginning fragment transaction by using childfragment manager.

layout:

                  <fragment
                    class="com.google.android.youtube.player.YouTubePlayerSupportFragment"
                    android:id="@+id/youtube_fragment"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

this is how i began fragment transaction:

   youTubePlayerFragment = (YouTubePlayerSupportFragment) getChildFragmentManager().findFragmentById(R.id.youtube_fragment);

the following codes explains how i removed the fragment which added by using childfragmentmanger.

@Override
    public void onDestroyView() {
        super.onDestroyView();

        youTubePlayerFragment = (YouTubePlayerSupportFragment) getChildFragmentManager().findFragmentById(R.id.youtube_fragment);

        if (youTubePlayerFragment != null)
        {
            getChildFragmentManager().beginTransaction().remove(youTubePlayerFragment).commitAllowingStateLoss();
        }

        youTubePlayer = null;
    }

JQuery Cookies

or plain Javascript:

function setCookie(c_name,value,exdays)
{
   var exdate=new Date();
   exdate.setDate(exdate.getDate() + exdays);
   var c_value=escape(value) + ((exdays==null) ? "" : ("; expires="+exdate.toUTCString()));
   document.cookie=c_name + "=" + c_value;
}

function getCookie(c_name)
{
   var i,x,y,ARRcookies=document.cookie.split(";");
   for (i=0; i<ARRcookies.length; i++)
   {
      x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
      y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
      x=x.replace(/^\s+|\s+$/g,"");
      if (x==c_name)
      {
        return unescape(y);
      }
   }
}

There is a attribute on every HTMLElement, "previousElementSibling".

Ex:

<div id="a">A</div>
<div id="b">B</div>
<div id="c">c</div>

<div id="result">Resultado: </div>

var b = document.getElementById("c").previousElementSibling;

document.getElementById("result").innerHTML += b.innerHTML;

I second Dave's idea. I'm not always fond of pivot tables, but in this case they are pretty straightforward to use.

Here are my results:

It was so simple to create it that I have even recorded a macro in case you need to do this with VBA:

Sub Macro2()
'
' Macro2 Macro
'

'
    Range("Table1[[#All],[DATA]]").Select
    ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
        "Table1", Version:=xlPivotTableVersion14).CreatePivotTable TableDestination _
        :="Sheet3!R3C7", TableName:="PivotTable4", DefaultVersion:= _
        xlPivotTableVersion14
    Sheets("Sheet3").Select
    Cells(3, 7).Select
    With ActiveSheet.PivotTables("PivotTable4").PivotFields("DATA")
        .Orientation = xlRowField
        .Position = 1
    End With
    ActiveSheet.PivotTables("PivotTable4").AddDataField ActiveSheet.PivotTables( _
        "PivotTable4").PivotFields("DATA"), "Count of DATA", xlCount
End Sub

For saving the original stdout and stderr you can use:

exec [fd number]<&1 
exec [fd number]<&2

For example, the following code will print "walla1" and "walla2" to the log file (a.txt), "walla3" to stdout, "walla4" to stderr.

#!/bin/bash

exec 5<&1
exec 6<&2

exec 1> ~/a.txt 2>&1

echo "walla1"
echo "walla2" >&2
echo "walla3" >&5
echo "walla4" >&6

there is no built-in feature to check that - what you would do is write your own tld function which takes a list and an item, and calls the list's contains() method. e.g.

//in your own WEB-INF/custom-functions.tld file add this
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
        PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
        "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib
        xmlns="http://java.sun.com/xml/ns/j2ee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
        version="2.0"
        >
    <tlib-version>1.0</tlib-version>
    <function>
        <name>contains</name>
        <function-class>com.Yourclass</function-class>
        <function-signature>boolean contains(java.util.List,java.lang.Object)
        </function-signature>
    </function>
</taglib>

Then create a class called Yourclass, and add a static method called contains with the above signature. I m sure the implementation of that method is pretty self explanatory:

package com; // just to illustrate how to represent the package in the tld
public class Yourclass {
   public static boolean contains(List list, Object o) {
      return list.contains(o);
   }
}

Then you can use it in your jsp:

<%@ taglib uri="/WEB-INF/custom-functions.tld" prefix="fn" %>
<c:if test="${  fn:contains( mylist, myValue ) }">style='display:none;'</c:if>

The tag can be used from any JSP in the site.

edit: more info regarding the tld file - more info here

There's an Abstract Class Dictionary

http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html

However this requires implementation.

Java gives us a nice implementation called a Hashtable

http://docs.oracle.com/javase/6/docs/api/java/util/Hashtable.html

I had the same problem. You probably haven't saved the file yet. Make sure to save your code with .py extension and it should work.

If you want to start coding Java to XML and XML to Java in less than 5 minutes, try Simple XML Serialization. Don't spend hours learning the JAXB API http://simple.sourceforge.net/download/stream/doc/tutorial/tutorial.php

However, if you are really keen on learning JAXB, here's an excellent tutorial http://blogs.oracle.com/teera/entry/jaxb_for_simple_java_xml

Contents of tutorial:

JAXB for simple Java-XML serialization

There're a number of way to do XML serialization in Java. If you want fine-grained control over parsing and serialization you can go for SAX, DOM, or Stax for better performance. Yet, what I often want to do is a simple mapping between POJOs and XML. However, creating Java classes to do XML event parsing manually is not trivial. I recently found JAXB to be a quick and convenient Java-XML mapping or serialization.

JAXB contains a lot of useful features, you can check out the reference implementation here. Kohsuke's Blog is also a good resource to learn more about JAXB. For this blog entry, I'll show you how to do a simple Java-XML serialization with JAXB.

POJO to XML

Let's say I have an Item Java object. I want to serialize an Item object to XML format. What I have to do first is to annotate this POJO with a few XML annotation from javax.xml.bind.annotation.* package. See code listing 1 for Item.java

From the code

• @XmlRootElement(name="Item") indicates that I want to be the root element.
• @XmlType(propOrder = {"name", "price"}) indicates the order that I want the element to be arranged in XML output.
• @XmlAttribute(name="id", ...) indicates that id is an attribute to root element.
• @XmlElement(....) indicates that I want price and name to be element within Item.

My Item.java is ready. I can then go ahead and create JAXB script for marshaling Item.

//creating Item data object
Item item = new Item();
item.setId(2);
item.setName("Foo");
item.setPrice(200);
.....

JAXBContext context = JAXBContext.newInstance(item.getClass());
Marshaller marshaller = context.createMarshaller();
//I want to save the output file to item.xml
marshaller.marshal(item, new FileWriter("item.xml"));

For complete code Listing please see Code Listing 2 main.java. The output Code Listing 3 item.xml file is created. It looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns1:item ns1:id="2" xmlns:ns1="http://blogs.sun.com/teera/ns/item">
  <ns1:itemName>Foo</ns1:itemName>
  <ns1:price>200</ns1:price>
</ns1:item>

Easy right? You can alternatively channel the output XML as text String, Stream, Writer, ContentHandler, etc by simply change the parameter of the marshal(...) method like

...
JAXBContext context = JAXBContext.newInstance(item.getClass());
Marshaller marshaller = context.createMarshaller();
// save xml output to the OutputStream instance
marshaller.marshal(item, <java.io.OutputStream instance>);

...
JAXBContext context = JAXBContext.newInstance(item.getClass());
Marshaller marshaller = context.createMarshaller();
StringWriter sw = new StringWriter();
//save to StringWriter, you can then call sw.toString() to get java.lang.String
marshaller.marshal(item, sw);

XML to POJO

Let's reverse the process. Assume that I now have a piece of XML string data and I want to turn it into Item.java object. XML data (Code listing 3) looks like

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns1:item ns1:id="2" xmlns:ns1="http://blogs.sun.com/teera/ns/item">
  <ns1:itemName>Bar</ns1:itemName>
  <ns1:price>80</ns1:price>
</ns1:item>

I can then unmarshal this xml code to Item object by

...
ByteArrayInputStream xmlContentBytes = new ByteArrayInputStream (xmlContent.getBytes());
JAXBContext context = JAXBContext.newInstance(Item.getClass());
Unmarshaller unmarshaller = context.createUnmarshaller();
//note: setting schema to null will turn validator off
unmarshaller.setSchema(null);
Object xmlObject = Item.getClass().cast(unmarshaller.unmarshal(xmlContentBytes));
return xmlObject;
...

For complete code Listing please see Code Listing 2 (main.java). The XML source can come in many forms both from Stream and file. The only difference, again, is the method parameter:

...
unmarshaller.unmarshal(new File("Item.xml")); // reading from file
...
// inputStream is an instance of java.io.InputStream, reading from stream
unmarshaller.unmarshal(inputStream);

Validation with XML Schema

Last thing I want to mention here is validating input XML with schema before unmarshalling to Java object. I create an XML schema file called item.xsd. For complete code Listing please see Code Listing 4 (Item.xsd). Now what I have to do is register this schema for validation.

...
Schema schema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI)
.newSchema(new File("Item.xsd"));
unmarshaller.setSchema(schema); //register item.xsd shcema for validation
...

When I try to unmarshal XML data to POJO, if the input XML is not conformed to the schema, exception will be caught. For complete code Listing please see Code Listing 5 (invalid_item.xml).

javax.xml.bind.UnmarshalException
- with linked exception:
javax.xml.bind.JAXBException caught: null
[org.xml.sax.SAXParseException: cvc-datatype-valid.1.2.1: 'item1' is
                                not a valid value for 'integer'.]

Here I change the 'id' attribute to string instead of integer.

If XML input is valid against the schema, the XML data will be unmarshalled to Item.java object successfully.

You can do it like this:

printf("%.6f", myFloat);

6 represents the number of digits after the decimal separator.

Remember that a single = is always an assignment in C or C++.

Your test should be if ( match == 0 && k == M )you made a typo on the k == M test.

If you really mean k=M (i.e. a side-effecting assignment inside a test) you should for readability reasons code if (match == 0 && (k=m) != 0) but most coding rules advise not writing that.

BTW, your mistake suggests to ask for all warnings (e.g. -Wall option to g++), and to upgrade to recent compilers. The next GCC 4.8 will give you:

 % g++-trunk -Wall -c ederman.cc
 ederman.cc: In function ‘void foo()’:
 ederman.cc:9:30: error: lvalue required as left operand of assignment
          if ( match == 0 && k = M )
                               ^

and Clang 3.1 also tells you ederman.cc:9:30: error: expression is not assignable

So use recent versions of free compilers and enable all the warnings when using them.

I had similar symptoms recently. Turned out it was caused by the Subversion server being unavailable - once that was restarted I was able to right-click. My environment was Eclipse Luna with Subclipse.

So worth checking that any connected source control systems are operational. Hope that helps.

Using a timespan would solve the problems as it has many attributes:

DateTime strt_date = DateTime.Now;
DateTime end_date = Convert.ToDateTime("10/1/2017 23:59:59");
//DateTime add_days = end_date.AddDays(1);
TimeSpan nod = (end_date - strt_date);

For code mirror divs refer to the manual, these sections might be useful to you:

http://codemirror.net/demo/fullscreen.html

var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
  lineNumbers: true,
  theme: "night",
  extraKeys: {
    "F11": function(cm) {
      cm.setOption("fullScreen", !cm.getOption("fullScreen"));
    },
    "Esc": function(cm) {
      if (cm.getOption("fullScreen")) cm.setOption("fullScreen", false);
    }
  }
});

And also take a look at:

http://codemirror.net/demo/resize.html

Also a comment:

Inline styling is horrible you should avoid this at all costs, not only will it confuse you, it's poor practice.

The scroll speed CAN be changed, adjusted, reversed, all of the above - via javascript (or a js library such as jQuery).

WHY would you want to do this? Parallax is just one of the reasons. I have no idea why anyone would argue against doing so -- the same negative arguments can be made against hiding DIVs, sliding elements up/down, etc. Websites are always a combination of technical functionality and UX design -- a good designer can use almost any technical capability to improve UX. That is what makes him/her good.

Toni Almeida of Portugal created a brilliant demo, reproduced below:

jsFiddle Demo

HTML:

<div id="myDiv">
    Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. <span class="boldit">Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. </span>
</div>

javascript/jQuery:

  function wheel(event) {
      var delta = 0;
      if (event.wheelDelta) {(delta = event.wheelDelta / 120);}
      else if (event.detail) {(delta = -event.detail / 3);}

      handle(delta);
      if (event.preventDefault) {(event.preventDefault());}
      event.returnValue = false;
  }

  function handle(delta) {
      var time = 1000;
      var distance = 300;

      $('html, body').stop().animate({
          scrollTop: $(window).scrollTop() - (distance * delta)
      }, time );
  }

  if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false);}
    window.onmousewheel = document.onmousewheel = wheel;

How to change default scrollspeed,scrollamount,scrollinertia of a webpage

Ideally you would use an ashx to send XML although I do allow code in an ASPX to intercept normal execution.

Response.Clear()

I don't use this if you not sure you've dumped anything in the response already the go find it and get rid of it.

Response.ContentType = "text/xml"

Definitely, a common client will not accept the content as XML without this content type present.

 Response.Charset = "UTF-8";

Let the response class handle building the content type header properly. Use UTF-8 unless you have a really, really good reason not to.

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(true);

If you don't send cache headers some browsers (namely IE) will cache the response, subsequent requests will not necessarily come to the server. You also need to AllowResponseInBrowser if you want this to work over HTTPS (due to yet another bug in IE).

To send content of an XmlDocument simply use:

dom.Save(Response.OutputStream);

dom.Save(Response.Output);

Just be sure the encodings match, (another good reason to use UTF-8).

The XmlDocument object will automatically adjust its embedded encoding="..." encoding to that of the Response (e.g. UTF-8)

Response.End()

If you really have to in an ASPX but its a bit drastic, in an ASHX don't do it.

I worked through this solution that accommodates a published, draft and historical versions of the data:

{
  published: {},
  draft: {},
  history: {
    "1" : {
      metadata: <value>,
      document: {}
    },
    ...
  }
}

I explain the model further here: http://software.danielwatrous.com/representing-revision-data-in-mongodb/

For those that may implement something like this in Java, here's an example:

http://software.danielwatrous.com/using-java-to-work-with-versioned-data/

Including all the code that you can fork, if you like

https://github.com/dwatrous/mongodb-revision-objects

The simplest way is to convert Date to POSIXlt format. Then perform the arithmetic operation as follows:

date_1m_fwd     <- as.POSIXlt("2010-01-01")
date_1m_fwd$mon <- date_1m_fwd$mon +1

Moreover, incase you want to deal with Date columns in data.table, unfortunately, POSIXlt format is not supported.

Still you can perform the add month using basic R codes as follows:

library(data.table)  
dt <- as.data.table(seq(as.Date("2010-01-01"), length.out=5, by="month"))  
dt[,shifted_month:=tail(seq(V1[1], length.out=length(V1)+3, by="month"),length(V1))]

Hope it helps.

I find this format the most useful as it includes the host field which is important in MySQL to distinguish between user records.

select User,Host from mysql.user;

Create your list before your loop, else it will be created at each loop.

>>> list1 = []
>>> for i in range(10) :
...   list1.append( range(i,10) )
...
>>> list1
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [1, 2, 3, 4, 5, 6, 7, 8, 9], [2, 3, 4, 5, 6, 7, 8, 9], [3, 4, 5, 6, 7, 8, 9], [4, 5, 6, 7, 8, 9], [5, 6, 7, 8, 9], [6, 7, 8, 9], [7, 8, 9], [8, 9], [9]]

best bet is targeting features not devices unless you have to, bootstrap do well and you can extend on their breakpoints, for instance targeting pixel density and larger screens above 1920

Updated for Swift 3

This worked for SQL Server 2005, 2008, and 2012. I found that the sys.identity_columns did not contain all my tables with identity columns.

SELECT a.name AS TableName, b.name AS IdentityColumn
FROM sys.sysobjects a 
JOIN sys.syscolumns b 
ON a.id = b.id
WHERE is_identity = 1
ORDER BY name;

Looking at the documentation page the status column can also be utilized. Also you can add the four part identifier and it will work across different servers.

SELECT a.name AS TableName, b.name AS IdentityColumn
FROM [YOUR_SERVER_NAME].[YOUR_DB_NAME].sys.sysobjects a 
JOIN [YOUR_SERVER_NAME].[YOUR_DB_NAME].sys.syscolumns b 
ON a.id = b.id
WHERE is_identity = 1
ORDER BY name;

After doing some research, this was happening in Ruby's XMLRPC::Client library - which uses NET::HTTP. The client uses the start() method in NET::HTTP which keeps the connection open for future requests.

This happened precisely at 30 seconds after the last requests - so my assumption here is that the server it's hitting is closing requests after that time. I'm not sure what the default is for NET::HTTP to keep the request open - but I'm about to test with 60 seconds to see if that solves the issue.

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

set ORACLE_SID=<YOUR_SID>
sqlplus "/as sysdba"
alter system disable restricted session;

or maybe

shutdown abort;

or maybe

lsnrctl stop

lsnrctl start

Works for me:

grep "\bsearch_word\b" text_file > output.txt  

\b indicates/sets boundaries.

Seems to work pretty fast

Last column in your input file must have some data in it (be it space or char, but not null). I guess, 1st record contains null after last ',' which sqlldr won't recognize unless specifically asked to recognize nulls using TRAILING NULLCOLS option. Alternatively, if you don't want to use TRAILING NULLCOLS, you will have to take care of those NULLs before you pass the file to sqlldr. Hope this helps

Swift 4:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "ExampleSegueIdentifier" {
        if let destinationVC = segue.destination as? ExampleSegueVC {
            destinationVC.exampleString = "Example"
        }
    }
}

Swift 3:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "ExampleSegueIdentifier" {
            if let destinationVC = segue.destinationViewController as? ExampleSegueVC {
                destinationVC.exampleString = "Example"
            }
        }
    }

Check something with echo, print() or printr() in the include file, header.php.

It might be that this is the problem OR if any MVC file, then check the number of spaces after ?>. This could also make a problem.

In order to generate release key hash you need to follow some easy steps.

1) Download Openssl

2) Make a openssl folder in C drive

3) Extract Zip files into this openssl folder created in C Drive.

4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)

5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.7.0_40\bin).

6) Copy the following code and hit enter

keytool -exportcert -alias abcd-keystore D:\Projects\MyAppFolder\keystore.txt | C:\openssl\bin\openssl sha1 - binary | C:\openssl\bin\openssl base64 ex - keytool -exportcert -alias (your sing apk alias name enter here like my sign apk alian name is abcd )-keystore "signed apk generated keystore apth enter here" | "openssl bin folder path enter here" sha1 - binary | "openssl bin folder path enter here" base64

7) Now you need to enter password, Password = (enter your sign keystore password here)

8) you got keystore which are used for release app key hash

You can use the following command to see if a service is running or not:

sc query [ServiceName] | findstr /i "STATE"

When I run it for my NOD32 Antivirus, I get:

STATE                       : 4 RUNNING

If it was stopped, I would get:

STATE                       : 1 STOPPED

You can use this in a variable to then determine whether you use NET START or not.

The service name should be the service name, not the display name.

If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json

Json(someDictionaryObj, JsonRequestBehavior.AllowGet);

Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5

as for your web request...it seems ok at first glance..

I would use something like this..

public void WebRequestinJson(string url, string postData)
    {
    StreamWriter requestWriter;

    var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
    if (webRequest != null)
    {
        webRequest.Method = "POST";
        webRequest.ServicePoint.Expect100Continue = false;
        webRequest.Timeout = 20000;

        webRequest.ContentType = "application/json";
        //POST the data.
        using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }
    }
}

May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.

How about str.split()? Nothing to import.

import os

image_names = [f for f in os.listdir(path) if len(f.split('.jpg')) == 2]

Use ffmpeglib to connect to the stream.

These functions may be useful. But take a look in the docs

av_open_input_stream(...);
av_find_stream_info(...);
avcodec_find_decoder(...);
avcodec_open(...);
avcodec_alloc_frame(...);

You would need a little algo to get a complete frame, which is available here

http://www.dranger.com/ffmpeg/tutorial01.html

Once you get a frame you could copy the video data (for each plane if needed) into a IplImage which is an OpenCV image object.

You can create an IplImage using something like...

IplImage *p_gray_image = cvCreateImage(size, IPL_DEPTH_8U, 1);

Once you have an IplImage, you could perform all sorts of image operations available in the OpenCV lib

This worked for me:
If it's a css file tap

<link href="{{ asset('css/app.css') }}" rel="stylesheet" type="text/css" >

If it's an image tap

<link href="{{ asset('css/img/logo.png') }}" rel="stylesheet" type="text/css" >

Other option:

SELECT CASE
    WHEN EXISTS (
        SELECT 1
        FROM [MyTable] AS [MyRecord])
    THEN CAST(1 AS BIT) ELSE CAST(0 AS BIT)
END

XAMPP comes preloaded with the FileZilla FTP server. Here is how to setup the service, and create an account.

1. Enable the FileZilla FTP Service through the XAMPP Control Panel to make it startup automatically (check the checkbox next to filezilla to install the service). Then manually start the service.

2. Create an ftp account through the FileZilla Server Interface (its the essentially the filezilla control panel). There is a link to it Start Menu in XAMPP folder. Then go to Users->Add User->Stuff->Done.

3. Try connecting to the server (localhost, port 21).

...because the .NET environment is designed to support many languages.

System.Boolean (in mscorlib.dll) is designed to be used internally by languages to support a boolean datatype. C# uses all lowercase for its keywords, hence 'bool', 'true', and 'false'.

VB.NET however uses standard casing: hence 'Boolean', 'True', and 'False'.

Since the languages have to work together, you couldn't have true.ToString() (C#) giving a different result to True.ToString() (VB.NET). The CLR designers picked the standard CLR casing notation for the ToString() result.

The string representation of the boolean true is defined to be Boolean.TrueString.

(There's a similar case with System.String: C# presents it as the 'string' type).

Use https://github.com/kristerkari/react-native-svg-transformer

In this package it is mentioned that .svg files are not supported in React Native v0.57 and lower so use .svgx extension for svg files.

For web or react-native-web use https://www.npmjs.com/package/@svgr/webpack

To render svg files using react-native-svg-uri with react-native version 0.57 and lower, you need to add following files to your root project

Note: change extension svg to svgx

step 1: add file transformer.js to project's root

// file: transformer.js

const cleanupSvg = require('./cleanup-svg');

const upstreamTransformer = require("metro/src/transformer");

// const typescriptTransformer = require("react-native-typescript-transformer");
// const typescriptExtensions = ["ts", "tsx"];

const svgExtensions = ["svgx"]

// function cleanUpSvg(text) {
//   text = text.replace(/width="([#0-9]+)px"/gi, "");
//    text = text.replace(/height="([#0-9]+)px"/gi, "");
//    return text;
// }

function fixRenderingBugs(content) {
  // content = cleanUpSvg(content); // cleanupSvg removes width and height attributes from svg
  return "module.exports = `" + content + "`";
}


module.exports.transform = function ({ src, filename, options }) {
  // if (typescriptExtensions.some(ext => filename.endsWith("." + ext))) {
  //  return typescriptTransformer.transform({ src, filename, options })
  // }

  if (svgExtensions.some(ext => filename.endsWith("." + ext))) {
    return upstreamTransformer.transform({
      src: fixRenderingBugs(src),
      filename,
      options
    })
  }

  return upstreamTransformer.transform({ src, filename, options });
}

step 2: add rn-cli.config.js to project's root

module.exports = {
    getTransformModulePath() {
      return require.resolve("./transformer");
    },
    getSourceExts() {
      return [/* "ts", "tsx", */ "svgx"];
    }
  };

The above mentioned solutions will work in production apps too ?

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

There should be no semicolon here:

class WordGame;

...but there should be one at the end of your class definition:

...
private:
    string theWord;
}; // <-- Semicolon should be at the end of your class definition

Like this?

public static void Test()
{
    using (var image = Image.FromFile(@"c:\logo.png"))
    using (var newImage = ScaleImage(image, 300, 400))
    {
        newImage.Save(@"c:\test.png", ImageFormat.Png);
    }
}

public static Image ScaleImage(Image image, int maxWidth, int maxHeight)
{
    var ratioX = (double)maxWidth / image.Width;
    var ratioY = (double)maxHeight / image.Height;
    var ratio = Math.Min(ratioX, ratioY);

    var newWidth = (int)(image.Width * ratio);
    var newHeight = (int)(image.Height * ratio);

    var newImage = new Bitmap(newWidth, newHeight);

    using (var graphics = Graphics.FromImage(newImage))
        graphics.DrawImage(image, 0, 0, newWidth, newHeight);

    return newImage;
}

There are of course a lot of good solutions based on what you need. If it is just configuration, you should have a look at Jakarta commons-configuration and commons-digester.

You could always use the standard JDK method of getting a document :

import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;

[...]

File file = new File("some/path");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(file);

Why the loop?

You could simply do this:

{% if 'priority' in data %}
    <p>Priority: {{ data['priority'] }}</p>
{% endif %}

When you were originally doing your string comparison, you should have used == instead.

I used the method below which really is a conundrum of all the ones above. I also found that onOptionsItemSelected is never activated.

    mDrawerToggle.setDrawerIndicatorEnabled(false);
    getSupportActionBar().setHomeButtonEnabled(true);

    Toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar);
    if (toolbar != null) {
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });
    }

Austin's answer works for your example case.

More generally, you would do well to look into the regular expression functions when the substring you're splitting on may differ between strings:

$variable = preg_replace('/By.*/', '', $variable);

string = "TEST"
try:
  if str(string):
     print "good string"
except NameError:
     print "bad string"

The "increment" portion of a loop statement has to change the value of the index variable to have any effect. The longhand form of "++j" is "j = j + 1". So, as other answers have said, the correct form of your increment is "j = j + 3", which doesn't have as terse a shorthand as incrementing by one. "j + 3", as you know by now, doesn't actually change j; it's an expression whose evaluation has no effect.

CLOSE_WAIT means your program is still running, and hasn't closed the socket (and the kernel is waiting for it to do so). Add -p to netstat to get the pid, and then kill it more forcefully (with SIGKILL if needed). That should get rid of your CLOSE_WAIT sockets. You can also use ps to find the pid.

SO_REUSEADDR is for servers and TIME_WAIT sockets, so doesn't apply here.

The best presentation for code in documents is in a fixed-width font (as it should appear in an IDE), with either a faint, shaded background or a light border to distinguish the block from other text.

Just make a custom userform that is shown when the "delete" button is pressed, then link the continue button to the actual code that does the deleting. Make the cancel button hide the userform.

It's called a Favicon, have a read.

<link rel="shortcut icon" href="http://www.example.com/myicon.ico"/>

You can use this neat tool to generate cross-browser compatible Favicons.

Steve Souders has already given a definitive answer but...

I wonder whether there's an issue with both Sam's original test and Josh's repeat of it.

Both tests appear to have been performed on low latency connections where setting up the TCP connection will have a trivial cost.

How this affects the result of the test I'm not sure and I'd want to look at the waterfalls for the tests over a 'normal' latency connection but...

The first file downloaded should get the connection used for the html page, and the second file downloaded will get the new connection. (Flushing the early alters that dynamic, but it's not being done here)

In newer browsers the second TCP connection is opened speculatively so the connection overhead is reduced / goes away, in older browsers this isn't true and the second connection will have the overhead of being opened.

Quite how/if this affects the outcome of the tests I'm not sure.

This one works for me

CREATE Function [dbo].[RemoveNumericCharacters](@Temp VarChar(1000))
Returns VarChar(1000)
AS
Begin

    Declare @NumRange as varchar(50) = '%[0-9]%'
    While PatIndex(@NumRange, @Temp) > 0
        Set @Temp = Stuff(@Temp, PatIndex(@NumRange, @Temp), 1, '')

    Return @Temp
End

and you can use it like so

SELECT dbo.[RemoveNumericCharacters](Name) FROM TARGET_TABLE

I am using Laravel 5.6 and the Notifications Facade.

If I set a variable with comma separating the e-mails and try to send it, I get the error: "Address in mail given does not comply with RFC 2822, 3.6.2"

So, to solve the problem, I got the solution idea from @Toskan, coding the following.

        // Get data from Database
        $contacts = Contacts::select('email')
            ->get();

        // Create an array element
        $contactList = [];
        $i=0;

        // Fill the array element
        foreach($contacts as $contact){
            $contactList[$i] = $contact->email;
            $i++;
        }

        .
        .
        .

        \Mail::send('emails.template', ['templateTitle'=>$templateTitle, 'templateMessage'=>$templateMessage, 'templateSalutation'=>$templateSalutation, 'templateCopyright'=>$templateCopyright], function($message) use($emailReply, $nameReply, $contactList) {
                $message->from('[email protected]', 'Some Company Name')
                        ->replyTo($emailReply, $nameReply)
                        ->bcc($contactList, 'Contact List')
                        ->subject("Subject title");
            });

It worked for me to send to one or many recipients.

Ned Deily's solution works perfectly fine, provided your user is allowed to sudo.

If he's not, you can su to an admin account, then use his dscl . append /Groups/_developer GroupMembership $user, where $user is the username.

However, I mistakenly thought it did not because I wrongly typed in the user's name in the command and it silently fails.

Therefore, after entering this command, you should proof-check it. This will check if $user is in $group, where the variables represent respectively the user name and the group name.

dsmemberutil checkmembership -U $user -G $group

This command will either print the message user is not a member of the group or user is a member of the group.

Vanilla JS solution:

var el = document.getElementById('changeProgramatic');
el.value='New Value'
el.dispatchEvent(new Event('change'));

Note that dispatchEvent doesn't work in old IE (see: caniuse). So you should probably only use it on internal websites (not on websites having wide audience).

So as of 2019 you just might want to make sure your customers/audience don't use Windows XP (yes, some still do in 2019). You might want to use conditional comments to warn customers that you don't support old IE (pre IE 11 in this case), but note that conditional comments only work until IE9 (don't work in IE10). So you might want to use feature detection instead. E.g. you could do an early check for: typeof document.body.dispatchEvent === 'function'.

There is a major gotcha associated with getting an ASCII code of a char value.

In the proper sense, it can't be done.

It's because char has a range of 65535 whereas ASCII is restricted to 128. There is a huge amount of characters that have no ASCII representation at all.

The proper way would be to use a Unicode code point which is the standard numerical equivalent of a character in the Java universe.

Thankfully, Unicode is a complete superset of ASCII. That means Unicode numbers for Latin characters are equal to their ASCII counterparts. For example, A in Unicode is U+0041 or 65 in decimal. In contrast, ASCII has no mapping for 99% of char-s. Long story short:

char ch = 'A';
int cp = String.valueOf(ch).codePointAt(0);

Furthermore, a 16-bit primitive char actually represents a code unit, not a character and is thus restricted to Basic Multilingual Plane, for historical reasons. Entities beyond it require Character objects which deal away with the fixed bit-length limitation.

Itemgetter lets you to sort by multiple criteria / columns:

sorted_list = sorted(list_to_sort, key=itemgetter(2,0,1))

You can do this using the Class.cast() method, which dynamically casts the supplied parameter to the type of the class instance you have. To get the class instance of a particular field, you use the getType() method on the field in question. I've given an example below, but note that it omits all error handling and shouldn't be used unmodified.

public class Test {

    public String var1;
    public Integer var2;
}

public class Main {

    public static void main(String[] args) throws Exception {
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("var1", "test");
        map.put("var2", 1);

        Test t = new Test();

        for (Map.Entry<String, Object> entry : map.entrySet()) {
            Field f = Test.class.getField(entry.getKey());

            f.set(t, f.getType().cast(entry.getValue()));
        }

        System.out.println(t.var1);
        System.out.println(t.var2);
    }
}

Commonly used in UIsegmentedControl, "error" appear when compiling in 64bits instead of 32bits, easy way for not pass it to a new variable is to use this tips, add (int):

[_monChiffre setUnite:(int)[_valUnites selectedSegmentIndex]];

instead of :

[_monChiffre setUnite:[_valUnites selectedSegmentIndex]];

Here's how to do this with java.nio operations:

public static void copyFile(File sourceFile, File destFile) throws IOException {
    if(!destFile.exists()) {
        destFile.createNewFile();
    }

    FileChannel source = null;
    FileChannel destination = null;
    try {
        source = new FileInputStream(sourceFile).getChannel();
        destination = new FileOutputStream(destFile).getChannel();

        // previous code: destination.transferFrom(source, 0, source.size());
        // to avoid infinite loops, should be:
        long count = 0;
        long size = source.size();              
        while((count += destination.transferFrom(source, count, size-count))<size);
    }
    finally {
        if(source != null) {
            source.close();
        }
        if(destination != null) {
            destination.close();
        }
    }
}

Since the methods used in other answers seems quite complicated for such easy task, here is a new answer:

Instead of a ListedColormap, which produces a discrete colormap, you may use a LinearSegmentedColormap. This can easily be created from a list using the from_list method.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors

x,y,c = zip(*np.random.rand(30,3)*4-2)

norm=plt.Normalize(-2,2)
cmap = matplotlib.colors.LinearSegmentedColormap.from_list("", ["red","violet","blue"])

plt.scatter(x,y,c=c, cmap=cmap, norm=norm)
plt.colorbar()
plt.show()

More generally, if you have a list of values (e.g. [-2., -1, 2]) and corresponding colors, (e.g. ["red","violet","blue"]), such that the nth value should correspond to the nth color, you can normalize the values and supply them as tuples to the from_list method.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors

x,y,c = zip(*np.random.rand(30,3)*4-2)

cvals  = [-2., -1, 2]
colors = ["red","violet","blue"]

norm=plt.Normalize(min(cvals),max(cvals))
tuples = list(zip(map(norm,cvals), colors))
cmap = matplotlib.colors.LinearSegmentedColormap.from_list("", tuples)

plt.scatter(x,y,c=c, cmap=cmap, norm=norm)
plt.colorbar()
plt.show()

With django 1.11, simply delete all migration files from the migrations folder of each application (all files except __init__.py). Then

1. Manually drop database.
2. Manually create database.
3. Run python3 manage.py makemigrations.
4. Run python3 manage.py migrate.

And voilla, your database has been completely reset.

Insted of using System.Net.WebClient I would recommend to have a look on System.Net.Http.HttpClient which was introduced with net 4.5 and makes your life much easier.

Also microsoft recommends to use the HttpClient on this article

http://msdn.microsoft.com/en-us/library/system.net.webclient(VS.90).aspx

An example could look like this:

var client = new HttpClient();
var content = new MultipartFormDataContent
{
     { new StringContent("myUserId"), "userid"},
     { new StringContent("myFileName"), "filename"},
     { new StringContent("myPassword"), "password"},
     { new StringContent("myType"), "type"}
};

var responseMessage = await client.PostAsync("some url", content);        
var stream = await responseMessage.Content.ReadAsStreamAsync();

You can also press = while less is open to just display (at the bottom of the screen) information about the current screen, including line numbers, with format:

myfile.txt lines 20530-20585/1816468 byte 1098945/116097872 1%  (press RETURN)

So here for example, the screen was currently showing lines 20530-20585, and the files has a total of 1816468 lines.

You can't do that in Javascript from the browser... If I were you, I would use something like browserify. Write your code using commonjs modules and then compile the javascript file into one.

In your html load the javascript file that you compiled.

MSDeploy can migrate all content, config, etc. that is what the IIS team recommends. http://www.iis.net/extensions/WebDeploymentTool

To create a package, run the following command (replace Default Web Site with your web site name):

msdeploy.exe -verb:sync -source:apphostconfig="Default Web Site" -dest:package=c:\dws.zip > DWSpackage7.log

To restore the package, run the following command:

msdeploy.exe -verb:sync -source:package=c:\dws.zip -dest:apphostconfig="Default Web Site" > DWSpackage7.log

You could set a margin for the table. Alternatively, wrap the table in a div and use the div's padding.

The method argument specifies the parameter of the smooth statistic. You can see stat_smooth for the list of all possible arguments to the method argument.

Java rule : One public class in one file.

I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important property.

HTML

<a href="#" class="selected_btn" data-role="button">Button name</a>

CSS

.selected_btn
{
    border:1px solid red;
    text-decoration:none;
    font-family:helvetica;
    color:red !important;            
    background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}

Here is the demo

The following articles will be useful

After you connect to the database issue the following command:

SET NAMES 'utf8';

Ensure that your web page also uses the UTF-8 encoding:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

PHP also offers several function that will be useful for conversions:

Actually, CheckBoxPreference does have the ability to specify a different summary based on the checkbox value. See the android:summaryOff and android:summaryOn attributes (as well as the corresponding CheckBoxPreference methods).

In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)

You can get the length of any 2nd dimension array as z[n].length where 0 <= n < z.length.

If you're treating your 2D array as a matrix, you can simply get z.length and z[0].length, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).

on os x these are the same for me... could this maybe be extra "\r" in windows?

in any case you may be better of with:

contents = File.read("e.tgz")
newFile = File.open("ee.tgz", "w")
newFile.write(contents)

You can also use sendmail:

/usr/sbin/sendmail [email protected] < /file/to/send

If git was to rename detached HEAD I would have it named as a HEAD that isn’t identified by a branch and will soon be forgotten.

We as people can easily remember branch names. We do git checkout new-button-feature / git checkout main. main and new-button-feature are easy to remember. And we can just do git branch and get a list of all branches. But to do the same with just commits you'd have to do git reflog which is very tedious. Because you have thousands of commits but only very few branches.

A detached commit’s identifier is just its SHA. So suppose you checked out a commit (not a branch) i.e. you did git checkout d747dd10e450871928a56c9cb7c6577cf61fdf31 you'll get:

Note: checking out 'd747dd10e450871928a56c9cb7c6577cf61fdf31'.

You are in 'detached HEAD' state.

...

Then if you made some changes and made a commit, you're still NOT on a branch.

Do you think you'd remember the commit SHA? You won't!

git doesn't want this to happen. Hence it's informing your HEAD is not associated to a branch so you're more inclined to checkout a new branch. As a result below that message it also says:

If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

To go a bit deeper a branch is built in a way that it's smart. It will update its HEAD as you make commits. Tags on the other hand are not meant to be like that. If you checkout a tag, then you're again on a detached HEAD. The main reason is that if you make a new commit from that tag then given that that commit is not referenced by anything (not any branch or tag) then still its considered a detached HEAD.

Attached HEADs can only happen when you're on a branch.

For more see here

HEAD is a pointer, and it points — directly or indirectly — to a particular commit:

Attached HEAD means that it is attached to some branch (i.e. it points to a branch).

Detached HEAD means that it is not attached to any branch, i.e. it points directly to some commit.

To look at from another angle, if you're on a branch and do cat .git/HEAD you'd get:

ref: refs/heads/Your-current-branch-name

Then if you do cat refs/heads/Your-current-branch-name then you'd also see the commit that your branch is pointing/referencing to.

However if you were on a detached HEAD you and cat .git/HEAD you'd just get the SHA of the commit and nothing more:

639ce5dd952a645b7c3fcbe89e88e3dd081a9912

By nothing more I mean the head isn't pointing to any branch. It's just directly pointing to a commit.

As a result of all this, anytime you checkout a commit, even if that commit was the latest commit of your main branch, you're still in a detached HEAD because your HEAD is not pointing to any branches. Hence even checking out a tag is will put you in a detached HEAD

Special thanks to Josh Caswell & Saagar Jha in helping me figure this out.

Yes. But place your "test" after the comma if you want the column...

> A <- matrix(sample(1:12,12,T),ncol=4)

> rownames(A) <- letters[1:3]

> colnames(A) <- letters[11:14]
> A[,"l"]
 a  b  c 
 6 10  1

We can use relative path instead of absolute path:

$assetPath: '~src/assets/images/';
$logo-img: '#{$assetPath}logo.png';
@mixin logo {
  background-image: url(#{$logo-img});
}

.logo {
    max-width: 65px;
    @include logo;
 }

It may seem weird, but I got started writing code by automating the tasks and data analysis at my former job. This was accomplished by recording then studying the code an Excel macro generated. Of course this approach assumes you can learn via VB.

I had a similar problem with é char... I think the comment "it's possible that the text you're feeding it isn't UTF-8" is probably close to the mark here. I have a feeling the default collation in my instance was something else until I realized and changed to utf8... problem is the data was already there, so not sure if it converted the data or not when i changed it, displays fine in mysql workbench. End result is that php will not json encode the data, just returns false. Doesn't matter what browser you use as its the server causing my issue, php will not parse the data to utf8 if this char is present. Like i say not sure if it is due to converting the schema to utf8 after data was present or just a php bug. In this case use json_encode(utf8_encode($string));

an inline solution combines Groot and Ivaylo suggestions in the format below:

onchange="(function(el){el.value=parseFloat(el.value).toFixed(2);})(this)"

You can install the package gcolor2 for this:

sudo apt-get install gcolor2

Then:

Applications -> Graphics -> GColor2

Method 1: Randomly selected tests. Long and ugly.

python -m pytest test/stress/test_performance.py::TestPerformance::test_continuous_trigger test/integration/test_config.py::TestConfig::test_valid_config

Method 2: Use Keyword Expressions.

Note: I am searching by testcase names. Same is applicable to TestClass names.

Case 1: The below will run whichever is found. Since we have used 'OR' .

python -m pytest -k 'test_password_valid or test_no_configuration'

Lets say the two above are actually correct, 2 tests will be run.

Case 2: Now an incorrect name and another correct name.

python -m pytest -k 'test_password_validzzzzzz or test_no_configuration' 

Only one is found and run.

Case 3: If you want all tests to run or no one, then use AND

python -m pytest -k 'test_password_valid and test_no_configuration'

Both will be run if correct or none.

Case 4: Run test only in one folder:

python -m pytest test/project1/integration -k 'test_password_valid or test_no_configuration'

Case 5: Run test from only one file.

python -m pytest test/integration/test_authentication.py -k 'test_password_expiry or test_incorrect_password'

Case 6: Run all tests except the match.

python -m pytest test/integration/test_authentication.py -k 'not  test_incorrect_password'

This expression 12-4-2005 is a calculated int and the value is -1997. You should do like this instead '2005-04-12' with the ' before and after.

The encodings are spelled out in the buffer documentation.

Buffers and character encodings:

Character Encodings

• utf8: Multi-byte encoded Unicode characters. Many web pages and other document formats use UTF-8. This is the default character encoding.
• utf16le: Multi-byte encoded Unicode characters. Unlike utf8, each character in the string will be encoded using either 2 or 4 bytes.
• latin1: Latin-1 stands for ISO-8859-1. This character encoding only supports the Unicode characters from U+0000 to U+00FF.

Binary-to-Text Encodings

• base64: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.
• hex: Encode each byte as two hexadecimal characters.

Legacy Character Encodings

• ascii: For 7-bit ASCII data only. Generally, there should be no reason to use this encoding, as 'utf8' (or, if the data is known to always be ASCII-only, 'latin1') will be a better choice when encoding or decoding ASCII-only text.
• binary: Alias for 'latin1'.
• ucs2: Alias of 'utf16le'.

I know this is really old, but this is the simplest way to query for Map.

Simply implement the ResultSetExtractor interface to define what type you want to return. Below is an example of how to use this. You'll be mapping it manually, but for a simple map, it should be straightforward.

jdbcTemplate.query("select string1,string2 from table where x=1", new ResultSetExtractor<Map>(){
    @Override
    public Map extractData(ResultSet rs) throws SQLException,DataAccessException {
        HashMap<String,String> mapRet= new HashMap<String,String>();
        while(rs.next()){
            mapRet.put(rs.getString("string1"),rs.getString("string2"));
        }
        return mapRet;
    }
});

This will give you a return type of Map that has multiple rows (however many your query returned) and not a list of Maps. You can view the ResultSetExtractor docs here: http://docs.spring.io/spring-framework/docs/2.5.6/api/org/springframework/jdbc/core/ResultSetExtractor.html

The function returns a static 2D array

const int N = 6;
int (*(MakeGridOfCounts)())[N] {
 static int cGrid[N][N] = {{0, }, {0, }, {0, }, {0, }, {0, }, {0, }};
 return cGrid;
}

int main() {
int (*arr)[N];
arr = MakeGridOfCounts();
}

You need to make the array static since it will be having a block scope, when the function call ends, the array will be created and destroyed. Static scope variables last till the end of program.

Without using external tools, if you are connecting to the server view SSH, this is a relatively easy command:

From a Windows 7+ command prompt:

ssh user@server cat /etc/passwd | clip

This will put the content of the remote file to your local clipboard.

(The command requires running Pageant for the key, or it will ask you for a password.)

Right Click on View > New Query

And Type: EXEC sp_rename 'Table', 'NewName'

Then Click on Run button at the top left corner of the page.

I think you want:

items.GroupBy(item => item.Order.Customer)
     .Select(group => new { Customer = group.Key, Items = group.ToList() })
     .ToList() 

If you want to continue use the overload of GroupBy you are currently using, you can do:

items.GroupBy(item => item.Order.Customer, 
              (key, group) =>  new { Customer = key, Items = group.ToList() })
     .ToList() 

...but I personally find that less clear.

1. Move the cursor to the n in name.
2. Enter visual block mode (Ctrlv).
3. Press j three times (or 3j).
4. Press I (capital i).
5. Type in vendor_. Note: It will only update the screen in the first line - until Esc is pressed (6.), at which point all lines will be updated.
6. Press Esc.

An uppercase I must be used rather than a lowercase i, because the lowercase i is interpreted as the start of a text object, which is rather useful on its own, e.g. for selecting inside a tag block (it):

If possible I would suggest creating the Path directly from the path elements:

Path path = Paths.get("C:", "dir1", "dir2", "dir3");
// if needed
String textPath = path.toString(); // "C:\\dir1\\dir2\\dir3"

There are quite a bit of answers to handle it client side, but you can change the output server side if you desired.

There are a few ways to approach this, I'll start with the basics. You'll have to subclass the JsonResult class and override the ExecuteResult method. From there you can take a few different approaches to change the serialization.

Approach 1: The default implementation uses the JsonScriptSerializer. If you take a look at the documentation, you can use the RegisterConverters method to add custom JavaScriptConverters. There are a few problems with this though: The JavaScriptConverter serializes to a dictionary, that is it takes an object and serializes to a Json dictionary. In order to make the object serialize to a string it requires a bit of hackery, see post. This particular hack will also escape the string.

public class CustomJsonResult : JsonResult
{
    private const string _dateFormat = "yyyy-MM-dd HH:mm:ss";

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }

        HttpResponseBase response = context.HttpContext.Response;

        if (!String.IsNullOrEmpty(ContentType))
        {
            response.ContentType = ContentType;
        }
        else
        {
            response.ContentType = "application/json";
        }
        if (ContentEncoding != null)
        {
            response.ContentEncoding = ContentEncoding;
        }
        if (Data != null)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();

            // Use your custom JavaScriptConverter subclass here.
            serializer.RegisterConverters(new JavascriptConverter[] { new CustomConverter });

            response.Write(serializer.Serialize(Data));
        }
    }
}

Approach 2 (recommended): The second approach is to start with the overridden JsonResult and go with another Json serializer, in my case the Json.NET serializer. This doesn't require the hackery of approach 1. Here is my implementation of the JsonResult subclass:

public class CustomJsonResult : JsonResult
{
    private const string _dateFormat = "yyyy-MM-dd HH:mm:ss";

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }

        HttpResponseBase response = context.HttpContext.Response;

        if (!String.IsNullOrEmpty(ContentType))
        {
            response.ContentType = ContentType;
        }
        else
        {
            response.ContentType = "application/json";
        }
        if (ContentEncoding != null)
        {
            response.ContentEncoding = ContentEncoding;
        }
        if (Data != null)
        {
            // Using Json.NET serializer
            var isoConvert = new IsoDateTimeConverter();
            isoConvert.DateTimeFormat = _dateFormat;
            response.Write(JsonConvert.SerializeObject(Data, isoConvert));
        }
    }
}

Usage Example:

[HttpGet]
public ActionResult Index() {
    return new CustomJsonResult { Data = new { users=db.Users.ToList(); } };
}

If you want to read the first lines quickly and you don't care about performance you can use .readlines() which returns list object and then slice the list.

E.g. for the first 5 lines:

with open("pathofmyfileandfileandname") as myfile:
    firstNlines=myfile.readlines()[0:5] #put here the interval you want

Note: the whole file is read so is not the best from the performance point of view but it is easy to use, fast to write and easy to remember so if you want just perform some one-time calculation is very convenient

print firstNlines

One advantage compared to the other answers is the possibility to select easily the range of lines e.g. skipping the first 10 lines [10:30] or the lasts 10 [:-10] or taking only even lines [::2].

In the popup window, overloads the method Show() with a parameter:

Public Overloads Sub Show(Caller As Window)
    Me.Owner = Caller
    MyBase.Show()
End Sub

Then in the Main window, call your overloaded method Show():

Dim Popup As PopupWindow

Popup = New PopupWindow
Popup.Show(Me)

As of November 30, 2020, AWS now has EC2 Mac instances:

• https://aws.amazon.com/ec2/instance-types/mac/

We previously used and had good experiences with:

• https://MacStadium.com/

Here are some other sites that I am aware of:

• https://flow.swiss/
• https://hostmyapple.com/ (We used them a long time ago, before MacStadium)
• https://macincloud.com/
• https://macminivault.com/
• https://macweb.com/
• https://virtualmacosx.com/
• https://xcloud.me/
• https://zeromac.com/
• http://www.cloud4mac.com/ 404 as of July, 2014
• https://www.macminicloud.net/ (Redirects to macweb.com)
• https://xcloud.me/ (Redirects to flow.swiss)

When we were with MacStadium, we loved them. We had great connectivity/uptime. When I've needed hands-on support to plug in a Time Machine backup, they've been great. They performed a seamless upgrade to better hardware for us over one weekend (when we could afford a bit of downtime), and that went off without a hitch. Highly recommended. (Not affiliated - just happy).

In April of 2020, we stopped using MacStadium, simply because we no longer needed a Mac server. If I need another Mac host, I would be happy to go back to them.

Using the ECMAScript 6 method String#repeat, a pad function is as simple as:

String.prototype.padLeft = function(char, length) { 
    return char.repeat(Math.max(0, length - this.length)) + this;
}

String#repeat is currently supported in Firefox and Chrome only. for other implementation, one might consider the following simple polyfill:

String.prototype.repeat = String.prototype.repeat || function(n){ 
    return n<=1 ? this : (this + this.repeat(n-1)); 
}

I think you missed a key point in the documentation for .add()

Mutates the original moment by adding time.

You appear to be treating it as a function that returns the immutable result. Easy mistake to make. :)

If you use the return value, it is the same actual object as the one you started with. It's just returned as a convenience for method chaining.

You can work around this behavior by cloning the moment, as described here.

Also, you cannot just use == to test. You could format each moment to the same output and compare those, or you could just use the .isSame() method.

Your code is now:

var timestring1 = "2013-05-09T00:00:00Z";
var timestring2 = "2013-05-09T02:00:00Z";
var startdate = moment(timestring1);
var expected_enddate = moment(timestring2);
var returned_endate = moment(startdate).add(2, 'hours');  // see the cloning?
returned_endate.isSame(expected_enddate)  // true

If e.preventDefault(); is not working you must use e.stopImmediatePropagation(); instead.

For further informations take a look at : What's the difference between event.stopPropagation and event.preventDefault?

$("div.subtab_left li.notebook a").click(function(e) {
    e.stopImmediatePropagation();
    return false;
});

You can do it programatically:

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
</activity>

Edit: I added some lines so that you can show it in fullscreen, as it seems that's what you want.

While padding programmatically, convert to density related values by converting pixel to Dp.

Here's a safe way for any iterable of delimiters, using regular expressions:

>>> import re
>>> delimiters = "a", "...", "(c)"
>>> example = "stackoverflow (c) is awesome... isn't it?"
>>> regexPattern = '|'.join(map(re.escape, delimiters))
>>> regexPattern
'a|\\.\\.\\.|\\(c\\)'
>>> re.split(regexPattern, example)
['st', 'ckoverflow ', ' is ', 'wesome', " isn't it?"]

re.escape allows to build the pattern automatically and have the delimiters escaped nicely.

Here's this solution as a function for your copy-pasting pleasure:

def split(delimiters, string, maxsplit=0):
    import re
    regexPattern = '|'.join(map(re.escape, delimiters))
    return re.split(regexPattern, string, maxsplit)

If you're going to split often using the same delimiters, compile your regular expression beforehand like described and use RegexObject.split.

If you'd like to leave the original delimiters in the string, you can change the regex to use a lookbehind assertion instead:

>>> import re
>>> delimiters = "a", "...", "(c)"
>>> example = "stackoverflow (c) is awesome... isn't it?"
>>> regexPattern = '|'.join('(?<={})'.format(re.escape(delim)) for delim in delimiters)
>>> regexPattern
'(?<=a)|(?<=\\.\\.\\.)|(?<=\\(c\\))'
>>> re.split(regexPattern, example)
['sta', 'ckoverflow (c)', ' is a', 'wesome...', " isn't it?"]

(replace ?<= with ?= to attach the delimiters to the righthand side, instead of left)

If you want to remove all the data from all your tables, you might want to try the command python manage.py flush. This will delete all of the data in your tables, but the tables themselves will still exist.

See more here: https://docs.djangoproject.com/en/1.8/ref/django-admin/

I would recommend the call_user_func() or call_user_func_arrayphp methods. You can check them out here (call_user_func_array , call_user_func).

example

class Foo {
static public function test() {
    print "Hello world!\n";
}
}

 call_user_func('Foo::test');//FOO is the class, test is the method both separated by ::
 //or
 call_user_func(array('Foo', 'test'));//alternatively you can pass the class and method as an array

If you have arguments you are passing to the method , then use the call_user_func_array() function.

example.

class foo {
function bar($arg, $arg2) {
    echo __METHOD__, " got $arg and $arg2\n";
}
}

// Call the $foo->bar() method with 2 arguments
call_user_func_array(array("foo", "bar"), array("three", "four"));
//or
//FOO is the class, bar is the method both separated by ::
call_user_func_array("foo::bar"), array("three", "four"));

moment.js FTW!!!

Just convert your date to a moment and manipulate it however you please:

var d = new Date(twDate);
var m = moment(d).format();
console.log(m);
// example output:
// 2016-01-08T00:00:00-06:00

I've been stuck with the same issue, and the preceding answer did not help me (albeit well written).

The solution is here : check your /etc/redis/redis.conf, and make sure to change the default

bind 127.0.0.1

to

bind 0.0.0.0

Then restart your service (service redis-server restart)

You can then now check that redis is listening on non-local interface with

redis-cli -h 192.168.x.x ping

(replace 192.168.x.x with your IP adress)

Important note : as several users stated, it is not safe to set this on a server which is exposed to the Internet. You should be certain that you redis is protected with any means that fits your needs.

Try this:

select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;

Apart from the performance reasons mentioned above, if your class stores references to objects passed as constructor parameters or your class has const variables then you don't have any choice except using initializer lists.

Assuming that windowing works on SQL Server 2008 like it does elsewhere (that I've tried), give this a go:

select testtable.*, sum(somevalue) over(order by somedate)
from testtable
order by somedate;

MSDN says it's available in SQL Server 2008 (and maybe 2005 as well?) but I don't have an instance to hand to try it.

EDIT: well, apparently SQL Server doesn't allow a window specification ("OVER(...)") without specifying "PARTITION BY" (dividing the result up into groups but not aggregating in quite the way GROUP BY does). Annoying-- the MSDN syntax reference suggests that its optional, but I only have SqlServer 2000 instances around at the moment.

The query I gave works in both Oracle 10.2.0.3.0 and PostgreSQL 8.4-beta. So tell MS to catch up ;)

SQLite doesn't support native variable syntax, but you can achieve virtually the same using an in-memory temp table.

I've used the below approach for large projects and works like a charm.

/* Create in-memory temp table for variables */
BEGIN;

PRAGMA temp_store = 2;
CREATE TEMP TABLE _Variables(Name TEXT PRIMARY KEY, RealValue REAL, IntegerValue INTEGER, BlobValue BLOB, TextValue TEXT);

/* Declaring a variable */
INSERT INTO _Variables (Name) VALUES ('VariableName');

/* Assigning a variable (pick the right storage class) */
UPDATE _Variables SET IntegerValue = ... WHERE Name = 'VariableName';

/* Getting variable value (use within expression) */
... (SELECT coalesce(RealValue, IntegerValue, BlobValue, TextValue) FROM _Variables WHERE Name = 'VariableName' LIMIT 1) ...

DROP TABLE _Variables;
END;

It's simpler to use, the -a option :

cat ~/campaigns/release-status.html | mail -s "Release Status [Green]" -a "Content-Type: text/html" [email protected]

I have a similar solution to @Satheesh using React hooks:

State initialization:

const [enteredText, setEnteredText] = useState(''); 

Input tag:

<input type="text" value={enteredText}  (event handler, classNames, etc.) />

Inside the event handler function, after updating the object with data from input form, call:

setEnteredText('');

Note: This is described as 'two-way binding'

try

$conn = mysql_connect($host, $username, $password, $port);

This example will exit after 5 seconds if another instance is already running.

// unique id for global mutex - Global prefix means it is global to the machine
const string mutex_id = "Global\\{B1E7934A-F688-417f-8FCB-65C3985E9E27}";

static void Main(string[] args)
{

    using (var mutex = new Mutex(false, mutex_id))
    {
        try
        {
            try
            {
                if (!mutex.WaitOne(TimeSpan.FromSeconds(5), false))
                {
                    Console.WriteLine("Another instance of this program is running");
                    Environment.Exit(0);
                }
            }
            catch (AbandonedMutexException)
            {
                // Log the fact the mutex was abandoned in another process, it will still get aquired
            }

            // Perform your work here.
        }
        finally
        {
            mutex.ReleaseMutex();
        }
    }
}

Don't loop through a file this way. Instead use a for loop.

for line in f:
    vowel += sum(ch.isvowel() for ch in line)

In fact your whole program is just:

VOWELS = {'A','E','I','O','U','a','e','i','o','u'}
# I'm assuming this is what isvowel checks, unless you're doing something
# fancy to check if 'y' is a vowel
with open('filename.txt') as f:
    vowel = sum(ch in VOWELS for line in f for ch in line.strip())

That said, if you really want to keep using a while loop for some misguided reason:

while True:
    line = f.readline().strip()
    if line == '':
        # either end of file or just a blank line.....
        # we'll assume EOF, because we don't have a choice with the while loop!
        break

You could also use T-Regx library:

pattern('\D')->remove($c)

T-Regx also:

• Throws exceptions on fail (not false, null or warnings)
• Has automatic delimiters (delimiters are not required!)
• Has a lot cleaner api

As of Java 7, java.util.logging.SimpleFormatter supports getting its format from a system property, so adding something like this to the JVM command line will cause it to print on one line:

-Djava.util.logging.SimpleFormatter.format='%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$s %2$s %5$s%6$s%n'

Alternatively, you can also add this to your logger.properties:

java.util.logging.SimpleFormatter.format='%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$s %2$s %5$s%6$s%n'

In my case, my xml had multiple namespaces and attributes. So I used this site to generate the objects - https://xmltocsharp.azurewebsites.net/

And used the below code to deserialize

 XmlDocument doc =  new XmlDocument();
        doc.Load("PathTo.xml");
        User obj;
        using (TextReader textReader = new StringReader(doc.OuterXml))
        {
            using (XmlTextReader reader = new XmlTextReader(textReader))
            {
                XmlSerializer serializer = new XmlSerializer(typeof(User));
                obj = (User)serializer.Deserialize(reader);
            }
        }

Yes, you can get it from the File object by using File.toPath(). Keep in mind that this is only for Java 7+. Java versions 6 and below do not have it.

A YAML sequence is an array. So this is the right way to express it:

key:
  - string1
  - string2      
  - string3
  - string4
  - string5
  - string6

That's identical in meaning to:

key: ['string1', 'string2', 'string3', 'string4', 'string5', 'string6']

It's also legal to split a single-line array over several lines:

key: ['string1', 'string2', 'string3', 
  'string4', 'string5', 
  'string6']

and even have multi-line strings in single-line arrays:

key: ['string1', 'long
  string', 'string3', 'string4', 'string5', 'string6']

The tool ydump is a JSON pretty-printer:

$ ydump my_data.json
{
  "foo": "lorem",
  "bar": "ipsum"
}

Or you can pipe in the JSON:

$ echo '{"foo": "lorem", "bar": "ipsum"}' | ydump
{
  "foo": "lorem",
  "bar": "ipsum"
}

This is probably the shortest solution apart from using the jq tool.

This tool is part of the yojson library for OCaml, and is documented here.

On Debian and derivatives, the package libyojson-ocaml-dev contains this tool. Alternatively, yojson can be installed via OPAM.

I don't think it's possible unless you use a flash, activex or java uploader.

For security reasons ajax / javascript isn't allowed to access the file stream or file properties before or during upload.

Use NSNumberFormatter with maximumFractionDigits as below:

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.maximumFractionDigits = 2;
NSLog(@"%@", [formatter stringFromNumber:[NSNumber numberWithFloat:12.345]]);

And you will get 12.35

You should be able to create a query with this filter here:

(&(objectClass=user)(sAMAccountName=yourUserName)
  (memberof=CN=YourGroup,OU=Users,DC=YourDomain,DC=com))

and when you run that against your LDAP server, if you get a result, your user "yourUserName" is indeed a member of the group "CN=YourGroup,OU=Users,DC=YourDomain,DC=com

Try and see if this works!

If you use C# / VB.Net and System.DirectoryServices, this snippet should do the trick:

DirectoryEntry rootEntry = new DirectoryEntry("LDAP://dc=yourcompany,dc=com");

DirectorySearcher srch = new DirectorySearcher(rootEntry);
srch.SearchScope = SearchScope.Subtree;

srch.Filter = "(&(objectClass=user)(sAMAccountName=yourusername)(memberOf=CN=yourgroup,OU=yourOU,DC=yourcompany,DC=com))";

SearchResultCollection res = srch.FindAll();

if(res == null || res.Count <= 0) {
    Console.WriteLine("This user is *NOT* member of that group");
} else {
    Console.WriteLine("This user is INDEED a member of that group");
}

Word of caution: this will only test for immediate group memberships, and it will not test for membership in what is called the "primary group" (usually "cn=Users") in your domain. It does not handle nested memberships, e.g. User A is member of Group A which is member of Group B - that fact that User A is really a member of Group B as well doesn't get reflected here.

The whole point of a class is that you create an instance, and that instance encapsulates a set of data. So it's wrong to say that your variables are global within the scope of the class: say rather that an instance holds attributes, and that instance can refer to its own attributes in any of its code (via self.whatever). Similarly, any other code given an instance can use that instance to access the instance's attributes - ie instance.whatever.

My BASIC interpreter chops beginning and ending quotes with

str->pop_back();
str->erase(str->begin());

Of course, I always expect well-formed BASIC style strings, so I will abort with failed assert if not:

assert(str->front() == '"' && str->back() == '"');

Just my two cents.
