I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

You need to enclose your <parent> elements in a surrounding element as XML Documents can have only one root node:

<parents> <!-- I've added this tag -->
    <parent>
        <child>
            Text
        </child>
    </parent>
    <parent>
        <child>
            <grandchild>
                Text
            </grandchild>
            <grandchild>
                Text
            </grandchild>
        </child>
        <child>
            Text
        </child>
    </parent>
</parents> <!-- I've added this tag -->

As you're receiving this markup from somewhere else, rather than generating it yourself, you may have to do this yourself by treating the response as a string and wrapping it with appropriate tags, prior to attempting to parse it as XML.

So, you've a couple of choices:

1. Get the provider of the web service to return you actual XML that has one root node
2. Pre-process the XML, as I've suggested above, to add a root node
3. Pre-process the XML to split it into multiple chunks (i.e. one for each <parent> node) and process each as a distinct XML Document

I had a scenario where nested JSON had to be serialised in a linear fashion while form data is constructed, since this is how server expects values. So, I wrote a small recursive function which translates the JSON which is like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress":{
      "city":"Wonderland",
      "code":"8796682911767",
      "firstname":"Raj Pawan",
      "lastname":"Gumdal",
      "line1":"Addr Line 1",
      "line2":null,
      "state":"US-AS",
      "region":{
         "isocode":"US-AS"
      },
      "zip":"76767-6776"
   }
}

Into something like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress.city":"Wonderland",
   "billingAddress.code":"8796682911767",
   "billingAddress.firstname":"Raj Pawan",
   "billingAddress.lastname":"Gumdal",
   "billingAddress.line1":"Addr Line 1",
   "billingAddress.line2":null,
   "billingAddress.state":"US-AS",
   "billingAddress.region.isocode":"US-AS",
   "billingAddress.zip":"76767-6776"
}

The server would accept form data which is in this converted format.

Here is the function:

function jsonToFormData (inJSON, inTestJSON, inFormData, parentKey) {
    // http://stackoverflow.com/a/22783314/260665
    // Raj: Converts any nested JSON to formData.
    var form_data = inFormData || new FormData();
    var testJSON = inTestJSON || {};
    for ( var key in inJSON ) {
        // 1. If it is a recursion, then key has to be constructed like "parent.child" where parent JSON contains a child JSON
        // 2. Perform append data only if the value for key is not a JSON, recurse otherwise!
        var constructedKey = key;
        if (parentKey) {
            constructedKey = parentKey + "." + key;
        }

        var value = inJSON[key];
        if (value && value.constructor === {}.constructor) {
            // This is a JSON, we now need to recurse!
            jsonToFormData (value, testJSON, form_data, constructedKey);
        } else {
            form_data.append(constructedKey, inJSON[key]);
            testJSON[constructedKey] = inJSON[key];
        }
    }
    return form_data;
}

Invocation:

        var testJSON = {};
        var form_data = jsonToFormData (jsonForPost, testJSON);

I am using testJSON just to see the converted results since I would not be able to extract the contents of form_data. AJAX post call:

        $.ajax({
            type: "POST",
            url: somePostURL,
            data: form_data,
            processData : false,
            contentType : false,
            success: function (data) {
            },
            error: function (e) {
            }
        });

cleaner way to do this is using foreach

foreach(var item in li.Where(w => w.name =="di"))
{
   item.age=10;
}

To check the database connection state you can just simple do the following

if(con.State == ConnectionState.Open){}

<select name="typeFather"
    [(ngModel)]="type.typeFather">
        <option *ngFor="let type of types" [ngValue]="type">{{type.title}}</option>
</select>

that approach always gonna work, however If you have a dynamic list, make sure you load it before the model

Add the code below in the PageLoad Event:

ScriptManager.RegisterStartupScript(Page, this.GetType(), "myScript", "alert('OK Done.');", true);

In Terminal:

nano ~/.bash_profile 

Add lines:

export ANDROID_HOME=/YOUR_PATH_TO/android-sdk
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools:$PATH

Check it worked:

source ~/.bash_profile
echo $ANDROID_HOME

I was looking for a really simple way to get PHP to send a socket.io message to clients.

This doesn't require any additional PHP libraries - it just uses sockets.

Instead of trying to connect to the websocket interface like so many other solutions, just connect to the node.js server and use .on('data') to receive the message.

Then, socket.io can forward it along to clients.

Detect a connection from your PHP server in Node.js like this:

//You might have something like this - just included to show object setup
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

server.on("connection", function(s) {
    //If connection is from our server (localhost)
    if(s.remoteAddress == "::ffff:127.0.0.1") {
        s.on('data', function(buf) {
            var js = JSON.parse(buf);
            io.emit(js.msg,js.data); //Send the msg to socket.io clients
        });
    }
});

Here's the incredibly simple php code - I wrapped it in a function - you may come up with something better.

Note that 8080 is the port to my Node.js server - you may want to change.

function sio_message($message, $data) {
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    $result = socket_connect($socket, '127.0.0.1', 8080);
    if(!$result) {
        die('cannot connect '.socket_strerror(socket_last_error()).PHP_EOL);
    }
    $bytes = socket_write($socket, json_encode(Array("msg" => $message, "data" => $data)));
    socket_close($socket);
}

You can use it like this:

sio_message("chat message","Hello from PHP!");

You can also send arrays which are converted to json and passed along to clients.

sio_message("DataUpdate",Array("Data1" => "something", "Data2" => "something else"));

This is a useful way to "trust" that your clients are getting legitimate messages from the server.

You can also have PHP pass along database updates without having hundreds of clients query the database.

I wish I'd found this sooner - hope this helps!

Try this instead:

sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumall = str(sumall) # add this line
sumln = (int(sumall[0])+int(sumall[1]))
print "Your lucky number is", sumln

sumall is a number, and you can't access its digits using the subscript notation (sumall[0], sumall[1]). For that to work, you'll need to transform it back to a string.

Just a pure javascript version (without jquery) of the great amirnissim's solution:

listener = function(event) {
      var suggestion_selected = document.getElementsByClassName('.pac-item-selected').length > 0;
      if (event.which === 13 && !suggestion_selected) {
        var e = JSON.parse(JSON.stringify(event));
        e.which = 40;
        e.keyCode = 40;
        orig_listener.apply(input, [e]);
      }
      orig_listener.apply(input, [event]);
    };

It is possible to SSH to Travis CI environment via a bounce host. The feature isn't built in Travis CI, but it can be achieved by the following steps.

1. On the bounce host, create travis user and ensure that you can SSH to it.

2. Put these lines in the script: section of your .travis.yml (e.g. at the end).

   - echo travis:$sshpassword | sudo chpasswd
   - sudo sed -i 's/ChallengeResponseAuthentication no/ChallengeResponseAuthentication yes/' /etc/ssh/sshd_config
   - sudo service ssh restart
   - sudo apt-get install sshpass
   - sshpass -p $sshpassword ssh -R 9999:localhost:22 -o StrictHostKeyChecking=no travis@$bouncehostip
   

   ^{Where $bouncehostip is the IP/host of your bounce host, and $sshpassword is your defined SSH password. These variables can be added as encrypted variables.}

3. Push the changes. You should be able to make an SSH connection to your bounce host.

Source: Shell into Travis CI Build Environment.

Here is the full example:

# use the new container infrastructure
sudo: required
dist: trusty

language: python
python: "2.7"

script:
- echo travis:$sshpassword | sudo chpasswd
- sudo sed -i 's/ChallengeResponseAuthentication no/ChallengeResponseAuthentication yes/' /etc/ssh/sshd_config
- sudo service ssh restart
- sudo apt-get install sshpass
- sshpass -p $sshpassword ssh -R 9999:localhost:22 -o StrictHostKeyChecking=no travisci@$bouncehostip

Im not a java developer but was using a java app to test a RESTful API. In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.

• CA.crt
• UTNAddTrustServer_CA.crt
• AddTrustExternalCARoot.crt

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>

Look at java.lang.BigDecimal, may solve your problem.

What is an enum

• enum is a keyword defined for Enumeration a new data type. Typesafe enumerations should be used liberally. In particular, they are a robust alternative to the simple String or int constants used in much older APIs to represent sets of related items.

Why to use enum

• enums are implicitly final subclasses of java.lang.Enum
• if an enum is a member of a class, it's implicitly static
• new can never be used with an enum, even within the enum type itself
• name and valueOf simply use the text of the enum constants, while toString may be overridden to provide any content, if desired
• for enum constants, equals and == amount to the same thing, and can be used interchangeably
• enum constants are implicitly public static final

Note

• enums cannot extend any class.
• An enum cannot be a superclass.
• the order of appearance of enum constants is called their "natural order", and defines the order used by other items as well: compareTo, iteration order of values, EnumSet, EnumSet.range.
• An enumeration can have constructors, static and instance blocks, variables, and methods but cannot have abstract methods.

To set it programmatically in Activity.java:

public void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setTheme(R.style.MyTheme); // (for Custom theme)
  setTheme(android.R.style.Theme_Holo); // (for Android Built In Theme)

  this.setContentView(R.layout.myactivity);

To set in Application scope in Manifest.xml (all activities):

 <application
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To set in Activity scope in Manifest.xml (single activity):

  <activity
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To build a custom theme, you will have to declare theme in themes.xml file, and set styles in styles.xml file.

A submodule may be marked as dirty if filemode settings is enabled and you changed file permissions in submodule subtree.

To disable filemode in a submodule, you can edit /.git/modules/path/to/your/submodule/config and add

[core]
  filemode = false

If you want to ignore all dirty states, you can either set ignore = dirty property in /.gitmodules file, but I think it's better to only disable filemode.

It does appear red on Firefox and IE 8. But perhaps you need to change the border-style too.

.field_set{_x000D_
  border-color: #F00;_x000D_
  border-style: solid;_x000D_
}

<fieldset class="field_set">_x000D_
  <legend>box</legend>_x000D_
  <table width="100%" border="0" cellspacing="0" cellpadding="0">_x000D_
    <tr>_x000D_
      <td>&nbsp;</td>_x000D_
    </tr>_x000D_
  </table>_x000D_
</fieldset>

Start by turning the text into a list of lists. That will take care of the parsing part:

lol = list(csv.reader(open('text.txt', 'rb'), delimiter='\t'))

The rest can be done with indexed lookups:

d = dict()
key = lol[6][0]      # cell A7
value = lol[6][3]    # cell D7
d[key] = value       # add the entry to the dictionary
 ...

With coming in of Java NIO, below is a possible solution too

With Java 9:

private static void copyDir(String src, String dest, boolean overwrite) {
    try {
        Files.walk(Paths.get(src)).forEach(a -> {
            Path b = Paths.get(dest, a.toString().substring(src.length()));
            try {
                if (!a.toString().equals(src))
                    Files.copy(a, b, overwrite ? new CopyOption[]{StandardCopyOption.REPLACE_EXISTING} : new CopyOption[]{});
            } catch (IOException e) {
                e.printStackTrace();
            }
        });
    } catch (IOException e) {
        //permission issue
        e.printStackTrace();
    }
}

With Java 7:

import java.io.IOException;
import java.nio.file.FileAlreadyExistsException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.function.Consumer;
import java.util.stream.Stream;

public class Test {

    public static void main(String[] args) {
        Path sourceParentFolder = Paths.get("/sourceParent");
        Path destinationParentFolder = Paths.get("/destination/");

        try {
            Stream<Path> allFilesPathStream = Files.walk(sourceParentFolder);
            Consumer<? super Path> action = new Consumer<Path>(){

                @Override
                public void accept(Path t) {
                    try {
                        String destinationPath = t.toString().replaceAll(sourceParentFolder.toString(), destinationParentFolder.toString());
                        Files.copy(t, Paths.get(destinationPath));
                    } 
                    catch(FileAlreadyExistsException e){
                        //TODO do acc to business needs
                    }
                    catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                }

            };
            allFilesPathStream.forEach(action );

        } catch(FileAlreadyExistsException e) {
            //file already exists and unable to copy
        } catch (IOException e) {
            //permission issue
            e.printStackTrace();
        }

    }

}

Here it is in C# (lat and long in radians):

double CalculateGreatCircleDistance(double lat1, double long1, double lat2, double long2, double radius)
{
    return radius * Math.Acos(
        Math.Sin(lat1) * Math.Sin(lat2)
        + Math.Cos(lat1) * Math.Cos(lat2) * Math.Cos(long2 - long1));
}

If your lat and long are in degrees then divide by 180/PI to convert to radians.

Dreamhost now includes SoapClient in their PHP 5.3 builds. You can switch your version of php in the domain setup section of the dreamhost control panel.

Had the exact same problem and none of the answers here helped me. Till I find this thread and post

Short: win32 modules are not guaranted to install correctly with pip. Install them directly from packages provided by developpers on github. It works like a charm.

The easiest way is to install the latest Git from here. And while installing, make sure you are enabling the option Windows Explorer Integration.

Once you are done, you will get those options in whenever you right click on any folder.

Hope it helps.

Recently I had similar problem, I solved it by importing a HTML file, the baseline example would be like this:

<html xmlns:v="urn:schemas-microsoft-com:vml"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">
  <head>
    <style>
      <!--
      br {mso-data-placement:same-cell;}
      -->
    </style>
  </head>
  <body>
    <table>
      <tr>
        <td>first line<br/>second line</td>
        <td style="white-space:normal">first line<br/>second line</td>
      </tr>
    </table>
  </body>
</html>

I know, it is not a CSV, and might work differently for various versions of Excel, but I think it is worth a try.

I hope this helps ;-)

You can use a named function on the constructor.

MyClass1 = function foo(id, member) {
    this.id = id;
    this.member = member;
}

var myobject = new MyClass1("5678999", "text");

console.log( myobject.constructor );

//function foo(id, member) {
//    this.id = id;
//    this.member = member;
//}

You could use a regex to parse out 'foo' from myobject.constructor and use that to get the name.

Using JQuery : http://api.jquery.com/hide/

$('li.two').hide()

In :

<ul class="lul">
    <li class="one">a</li>
    <li class="two">b</li>
    <li class="three">c</li>
</ul>

If you want to return from an outer function with an error without exiting you can use this trick:

do-something-complex() {
  # Using `return` here would only return from `fail`, not from `do-something-complex`.
  # Using `exit` would close the entire shell.
  # So we (ab)use a different feature. :)
  fail() { : "${__fail_fast:?$1}"; }

  nested-func() {
      try-this || fail "This didn't work"
      try-that || fail "That didn't work"
  }
  nested-func
}

Trying it out:

$ do-something-complex
try-this: command not found
bash: __fail_fast: This didn't work

This has the added benefit/drawback that you can optionally turn off this feature: __fail_fast=x do-something-complex.

Note that this causes the outermost function to return 1.

find / -print will do this

There are different ways to do that.

• I created the data frame to showcase the different techniques to filter your data.

df = pd.DataFrame({'Date':['01-Jun-13','03-Jun-13', '15-Aug-13', '20-Jan-14', '21-Feb-14'],

'abc':[100,-20,40,25,60],'xyz':[200,50,-5,15,80] })

• I separated months/year/day and seperated month-year as you explained.

def getMonth(s):
  return s.split("-")[1]

def getDay(s):
  return s.split("-")[0]

def getYear(s):
  return s.split("-")[2]

def getYearMonth(s):
  return s.split("-")[1]+"-"+s.split("-")[2]

• I created new columns: year, month, day and 'yearMonth'. In your case, you need one of both. You can group using two columns 'year','month' or using one column yearMonth

df['year']= df['Date'].apply(lambda x: getYear(x))
df['month']= df['Date'].apply(lambda x: getMonth(x))
df['day']= df['Date'].apply(lambda x: getDay(x))
df['YearMonth']= df['Date'].apply(lambda x: getYearMonth(x))

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
3  20-Jan-14   25   15   14   Jan  20    Jan-14
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• You can go through the different groups in groupby(..) items.

In this case, we are grouping by two columns:

for key,g in df.groupby(['year','month']):
    print key,g

Output:

('13', 'Jun')         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
('13', 'Aug')         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
('14', 'Jan')         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
('14', 'Feb')         Date  abc  xyz year month day YearMonth

In this case, we are grouping by one column:

for key,g in df.groupby(['YearMonth']):
    print key,g

Output:

Jun-13         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
Aug-13         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
Jan-14         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
Feb-14         Date  abc  xyz year month day YearMonth
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• In case you wanna access to specific item, you can use get_group

print df.groupby(['YearMonth']).get_group('Jun-13')

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

• Similar to get_group. This hack would help to filter values and get the grouped values.

This also would give the same result.

print df[df['YearMonth']=='Jun-13'] 

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

You can select list of abc or xyz values during Jun-13

print df[df['YearMonth']=='Jun-13'].abc.values
print df[df['YearMonth']=='Jun-13'].xyz.values

Output:

[100 -20]  #abc values
[200  50]  #xyz values

You can use this to go through the dates that you have classified as "year-month" and apply cretiria on it to get related data.

for x in set(df.YearMonth): 
    print df[df['YearMonth']==x].abc.values
    print df[df['YearMonth']==x].xyz.values

• With Jenkins CLI you do not have to reload everything - you just can load the job (update-job command). You can't use tokens with CLI, AFAIK - you have to use password or password file.

• Token name for user can be obtained via http://<jenkins-server>/user/<username>/configure - push on 'Show API token' button.

• Here's a link on how to use API tokens (it uses wget, but curl is very similar).

DUAL is necessary in PL/SQL development for using functions that are only available in SQL

e.g.

DECLARE
x XMLTYPE;
BEGIN
SELECT xmlelement("hhh", 'stuff')
INTO x
FROM dual;
END;

you can follow BaseAdapter and create your custome Xml file and bind it with you BaseAdpter and populate it with Listview see here need to change xml file as Require.

$("#test").hide(100, function() {
    $(this).html("......").show(100);
});

Updated:

Another easy way:

$("#test").fadeOut(400, function() {
    $(this).html("......").fadeIn(400);
});

This is all you need, no wrapper needed:

.login-icon{
    display:inline-block;
    font-size: 40px;
    line-height: 50px;
    background-color:black;
    color:white;
    width: 50px;
    height: 50px;
    text-align: center;
    vertical-align: bottom;
}

You can take keys or values per index:

int value = _dict.Values.ElementAt(5);//ElementAt value should be <= _dict.Count - 1
string key = _dict.Keys.ElementAt(5);//ElementAt value should be  < =_dict.Count - 1

You can also use the following syntax for the strongly typed version:

<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(), 
          FormMethod.Post, 
          new { enctype = "multipart/form-data" })) 
   { %>

line=$(head -1 file)

Will work fine. (As previous answer). But

line=$(read -r FIRSTLINE < filename)

will be marginally faster as read is a built-in bash command.

Try by changing X[:,3] to X.iloc[:,3] in label encoder

I have fixed the problem, just need to check:

open_mode from v$database

and then check:

check account_status to get mode information

and then use:

alter user myuser identified by mynewpassword account unlock;

You can create a function:

function changeInputType(oldObj, oTyp, nValue) {
  var newObject = document.createElement('input');
  newObject.type = oTyp;
  if(oldObj.size) newObject.size = oldObj.size;
  if(oldObj.value) newObject.value = nValue;
  if(oldObj.name) newObject.name = oldObj.name;
  if(oldObj.id) newObject.id = oldObj.id;
  if(oldObj.className) newObject.className = oldObj.className;
  oldObj.parentNode.replaceChild(newObject,oldObj);
  return newObject;
}

And you do a call like:

changeInputType(document.getElementById('DATE_RANGE_VALUE'), 'checkbox', 7);

The prompt you're getting doesn't look like Subversion asking you for a password, it looks like ssh asking for a password. So my guess is that you have checked out an svn+ssh:// checkout, not an svn:// or http:// or https:// checkout.

IIRC all the options you're trying only work for the svn/http/https checkouts. Can you run svn info to confirm what kind of repository you are using ?

If you are using ssh, you should set up key-based authentication so that your scripts will work without prompting for a password.

Another improvement on large files with identical length, might be to not read the files sequentially, but rather compare more or less random blocks.

You can use multiple threads, starting on different positions in the file and comparing either forward or backwards.

This way you can detect changes at the middle/end of the file, faster than you would get there using a sequential approach.

From the title of this question I was expecting to find something like range(), that would let me specify two dates and create a list with all the dates in between. That way one does not need to calculate the number of days between those two dates, if one does not know it beforehand.

So with the risk of being slightly off-topic, this one-liner does the job:

import datetime
start_date = datetime.date(2011, 01, 01)
end_date   = datetime.date(2014, 01, 01)

dates_2011_2013 = [ start_date + datetime.timedelta(n) for n in range(int ((end_date - start_date).days))]

Set the UINavigationControllerDelegate and implement this delegate func (Swift):

func navigationController(navigationController: UINavigationController, willShowViewController viewController: UIViewController, animated: Bool) {
    if viewController is <target class> {
        //if the only way to get back - back button was pressed
    }
}

My suggestion, if you are still using const XXX = require('library or path./') when using module.exports to export multiple functions use an ES6 arrow function

for example:

module.exports = () => {

const  getPosts = (req, res ) =>{
    res.send('THIS WORKS!');
}

const getPost = async (req, res) => { 
    const { id } = req.params;

    try {
        const post = await PostMessage.findById(id);
        
        res.status(200).json(post);
    } catch (error) {
        res.status(404).json({ message: error.message });
    }
}

}

then Import: const getPosts = require('../controllers/posts.js');

Hope this helps... Cheers! www.miyamotto.net

If you are using Visual Studio then yes, you can do this.

The library builder tool that comes with Visual Studio allows you to join libraries together on the command line. I don't know of any way to do this in the visual editor though.

lib.exe /OUT:compositelib.lib  lib1.lib lib2.lib

def my_sort(lst):
    a = []
    for i in range(len(lst)):
        a.append(min(lst))
        lst.remove(min(lst))
    return a

def my_revers_sort(lst):#in revers!!!!!
    a = []
    for i in range(len(lst)):
        a.append(max(lst))
        lst.remove(max(lst))
    return a

Pandas 0.24.0+ solution

In Pandas 0.24.0 a new feature was introduced specifically designed for fast writes to Postgres. You can learn more about it here: https://pandas.pydata.org/pandas-docs/stable/user_guide/io.html#io-sql-method

import csv
from io import StringIO

from sqlalchemy import create_engine

def psql_insert_copy(table, conn, keys, data_iter):
    # gets a DBAPI connection that can provide a cursor
    dbapi_conn = conn.connection
    with dbapi_conn.cursor() as cur:
        s_buf = StringIO()
        writer = csv.writer(s_buf)
        writer.writerows(data_iter)
        s_buf.seek(0)

        columns = ', '.join('"{}"'.format(k) for k in keys)
        if table.schema:
            table_name = '{}.{}'.format(table.schema, table.name)
        else:
            table_name = table.name

        sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(

I needed to process the entire line as a whole. Here is what I found to work.

for /F "tokens=*" %%A in (myfile.txt) do [process] %%A

The tokens keyword with an asterisk (*) will pull all text for the entire line. If you don't put in the asterisk it will only pull the first word on the line. I assume it has to do with spaces.

For Command on TechNet

If there are spaces in your file path, you need to use usebackq. For example.

for /F "usebackq tokens=*" %%A in ("my file.txt") do [process] %%A

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()

Nope. That can't be done. The best 'way' of doing that is just making the expiration date be like 2100.

Thank god, this solved. After setting a text to the button, you can retrieve intrinsicContentSize which is the natural size from an UIView (the official document is here). For UIButton, you can use it like below.

button.intrinsicContentSize.width

For your information, I adjusted the width to make it look properly.

button.frame = CGRect(fx: xOffset, y: 0.0, width: button.intrinsicContentSize.width + 18, height: 40)

Fixed!

The reason was the dbpath variable in /etc/mongodb.conf. Previously, I was using mongodb 1.8, where the default value for dbpath was /data/db. The upstart job mongodb(which comes with mongodb-10gen package) invokes the mongod with --config /etc/mongodb.conf option.

As a solution, I only had to change the owner of the /data/db directory recursively.

In Java 7 and higher you can use listdir

Path dir = ...;
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir)) {
    for (Path file: stream) {
        System.out.println(file.getFileName());
    }
} catch (IOException | DirectoryIteratorException x) {
    // IOException can never be thrown by the iteration.
    // In this snippet, it can only be thrown by newDirectoryStream.
    System.err.println(x);
}

You can also create a filter that can then be passed into the newDirectoryStream method above

DirectoryStream.Filter<Path> filter = new DirectoryStream.Filter<Path>() {
    public boolean accept(Path file) throws IOException {
        try {
            return (Files.isRegularFile(path));
        } catch (IOException x) {
            // Failed to determine if it's a file.
            System.err.println(x);
            return false;
        }
    }
};

For other filtering examples, [see documentation].(http://docs.oracle.com/javase/tutorial/essential/io/dirs.html#glob)

I know this was quite a while ago, however I have a little extra to add:

This is not possible in HTML5 or any previous specs, nor is it proposed in HTML5.1 yet. I have made a request to the public-html-comments mailing list, but we'll see if anything comes of it.

Regardless, whilst this is not possible using <select> yet, you can achieve a similar effect with the following HTML, plus some CSS for prettiness:

As an extra added benefit, this also means you can allow selection of the <optgroups> themselves. This might be useful if you had, for example, nested categories where the categories go into heavy detail and you want to allow users to select higher up in the hierarchy.

This will all work without JavaScript, however you might wish to add some to hide the radio buttons and then change the background color of the selected item or something.

Bear in mind, this is far from a perfect solution, but if you absolutely need a nested select with reasonable cross-browser compatibility, this is probably as close as you're going to get.

JUnit 5 now has a @BeforeAll annotation:

Denotes that the annotated method should be executed before all @Test methods in the current class or class hierarchy; analogous to JUnit 4’s @BeforeClass. Such methods must be static.

The lifecycle annotations of JUnit 5 seem to have finally gotten it right! You can guess which annotations available without even looking (e.g. @BeforeEach @AfterAll)

Benny's answer on Windows with the Linux subsystem:

code --list-extensions | wsl xargs -L 1 echo code --install-extension

EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value syntax is incorrect.

I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. error message. In 2008, the modified script is still successful.

declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)

add following in your pom.xml .it works for me.

Use the constructor for appending material to the file:

FileOutputStream(File file, boolean append)
Creates a file output stream to write to the file represented by the specified File object.

So to append to a file say "abc.txt" use

FileOutputStream fos=new FileOutputStream(new File("abc.txt"),true);

Any MD5 will produce a good checksum to verify the file. Any of the files listed at the bottom of this page will work fine. http://en.wikipedia.org/wiki/Md5sum

Modified from this link. This will return as string, but you can modify as needed to return your datetime data type.

SELECT CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(GetDate())-1),GetDate()),101) 

You can easily create a timer functionality by using setInterval.Below is the code which you can use it to create the timer.

http://jsfiddle.net/ayyadurai/GXzhZ/1/

window.onload = function() {_x000D_

  var sec = 60;_x000D_
  setInterval(function() {_x000D_
    document.getElementById("timer").innerHTML = minute + " : " + sec;_x000D_
    sec--;_x000D_
    if (sec == 00) {_x000D_
      minute --;_x000D_
      sec = 60;_x000D_
      if (minute == 0) {_x000D_
        minute = 5;_x000D_
      }_x000D_
    }_x000D_
  }, 1000);_x000D_
}

Registration closes in <span id="timer">05:00<span> minutes!

If you are working from a windows forms application this worked for me

"server=localhost; user id=dbuser; password=password; database=dbname; Use Procedure Bodies=false;"

Just add the "Use Procedure Bodies=false" at the end of your connection string.

Why is gets() dangerous

The first internet worm (the Morris Internet Worm) escaped about 30 years ago (1988-11-02), and it used gets() and a buffer overflow as one of its methods of propagating from system to system. The basic problem is that the function doesn't know how big the buffer is, so it continues reading until it finds a newline or encounters EOF, and may overflow the bounds of the buffer it was given.

You should forget you ever heard that gets() existed.

The C11 standard ISO/IEC 9899:2011 eliminated gets() as a standard function, which is A Good Thing™ (it was formally marked as 'obsolescent' and 'deprecated' in ISO/IEC 9899:1999/Cor.3:2007 — Technical Corrigendum 3 for C99, and then removed in C11). Sadly, it will remain in libraries for many years (meaning 'decades') for reasons of backwards compatibility. If it were up to me, the implementation of gets() would become:

char *gets(char *buffer)
{
    assert(buffer != 0);
    abort();
    return 0;
}

Given that your code will crash anyway, sooner or later, it is better to head the trouble off sooner rather than later. I'd be prepared to add an error message:

fputs("obsolete and dangerous function gets() called\n", stderr);

Modern versions of the Linux compilation system generates warnings if you link gets() — and also for some other functions that also have security problems (mktemp(), …).

Alternatives to gets()

fgets()

As everyone else said, the canonical alternative to gets() is fgets() specifying stdin as the file stream.

char buffer[BUFSIZ];

while (fgets(buffer, sizeof(buffer), stdin) != 0)
{
    ...process line of data...
}

What no-one else yet mentioned is that gets() does not include the newline but fgets() does. So, you might need to use a wrapper around fgets() that deletes the newline:

char *fgets_wrapper(char *buffer, size_t buflen, FILE *fp)
{
    if (fgets(buffer, buflen, fp) != 0)
    {
        size_t len = strlen(buffer);
        if (len > 0 && buffer[len-1] == '\n')
            buffer[len-1] = '\0';
        return buffer;
    }
    return 0;
}

Or, better:

char *fgets_wrapper(char *buffer, size_t buflen, FILE *fp)
{
    if (fgets(buffer, buflen, fp) != 0)
    {
        buffer[strcspn(buffer, "\n")] = '\0';
        return buffer;
    }
    return 0;
}

Also, as caf points out in a comment and paxdiablo shows in his answer, with fgets() you might have data left over on a line. My wrapper code leaves that data to be read next time; you can readily modify it to gobble the rest of the line of data if you prefer:

        if (len > 0 && buffer[len-1] == '\n')
            buffer[len-1] = '\0';
        else
        {
             int ch;
             while ((ch = getc(fp)) != EOF && ch != '\n')
                 ;
        }

The residual problem is how to report the three different result states — EOF or error, line read and not truncated, and partial line read but data was truncated.

This problem doesn't arise with gets() because it doesn't know where your buffer ends and merrily tramples beyond the end, wreaking havoc on your beautifully tended memory layout, often messing up the return stack (a Stack Overflow) if the buffer is allocated on the stack, or trampling over the control information if the buffer is dynamically allocated, or copying data over other precious global (or module) variables if the buffer is statically allocated. None of these is a good idea — they epitomize the phrase 'undefined behaviour`.

There is also the TR 24731-1 (Technical Report from the C Standard Committee) which provides safer alternatives to a variety of functions, including gets():

§6.5.4.1 The gets_s function

Synopsis

#define __STDC_WANT_LIB_EXT1__ 1
#include <stdio.h>
char *gets_s(char *s, rsize_t n);

Runtime-constraints

s shall not be a null pointer. n shall neither be equal to zero nor be greater than RSIZE_MAX. A new-line character, end-of-file, or read error shall occur within reading n-1 characters from stdin.²⁵⁾

3 If there is a runtime-constraint violation, s[0] is set to the null character, and characters are read and discarded from stdin until a new-line character is read, or end-of-file or a read error occurs.

Description

4 The gets_s function reads at most one less than the number of characters specified by n from the stream pointed to by stdin, into the array pointed to by s. No additional characters are read after a new-line character (which is discarded) or after end-of-file. The discarded new-line character does not count towards number of characters read. A null character is written immediately after the last character read into the array.

5 If end-of-file is encountered and no characters have been read into the array, or if a read error occurs during the operation, then s[0] is set to the null character, and the other elements of s take unspecified values.

Recommended practice

6 The fgets function allows properly-written programs to safely process input lines too long to store in the result array. In general this requires that callers of fgets pay attention to the presence or absence of a new-line character in the result array. Consider using fgets (along with any needed processing based on new-line characters) instead of gets_s.

²⁵⁾ The gets_s function, unlike gets, makes it a runtime-constraint violation for a line of input to overflow the buffer to store it. Unlike fgets, gets_s maintains a one-to-one relationship between input lines and successful calls to gets_s. Programs that use gets expect such a relationship.

The Microsoft Visual Studio compilers implement an approximation to the TR 24731-1 standard, but there are differences between the signatures implemented by Microsoft and those in the TR.

The C11 standard, ISO/IEC 9899-2011, includes TR24731 in Annex K as an optional part of the library. Unfortunately, it is seldom implemented on Unix-like systems.

getline() — POSIX

POSIX 2008 also provides a safe alternative to gets() called getline(). It allocates space for the line dynamically, so you end up needing to free it. It removes the limitation on line length, therefore. It also returns the length of the data that was read, or -1 (and not EOF!), which means that null bytes in the input can be handled reliably. There is also a 'choose your own single-character delimiter' variation called getdelim(); this can be useful if you are dealing with the output from find -print0 where the ends of the file names are marked with an ASCII NUL '\0' character, for example.

I guess you had an error in the inline code of your image. Try this :

var image = document.createElement('img');_x000D_
    _x000D_
image.src="data:image/gif;base64,R0lGODlhDwAPAKECAAAAzMzM/////wAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4MLwWACH+H09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw==";_x000D_

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed). Use one of those.

You need to add a 640x1136 pixels PNG image ([email protected]) as a 4 inch default splash image of your project, and it will use extra spaces (without efforts on simple table based applications, games will require more efforts).

I've created a small UIDevice category in order to deal with all screen resolutions. You can get it here, but the code is as follows:

File UIDevice+Resolutions.h:

enum {
    UIDeviceResolution_Unknown           = 0,
    UIDeviceResolution_iPhoneStandard    = 1,    // iPhone 1,3,3GS Standard Display  (320x480px)
    UIDeviceResolution_iPhoneRetina4    = 2,    // iPhone 4,4S Retina Display 3.5"  (640x960px)
    UIDeviceResolution_iPhoneRetina5     = 3,    // iPhone 5 Retina Display 4"       (640x1136px)
    UIDeviceResolution_iPadStandard      = 4,    // iPad 1,2,mini Standard Display   (1024x768px)
    UIDeviceResolution_iPadRetina        = 5     // iPad 3 Retina Display            (2048x1536px)
}; typedef NSUInteger UIDeviceResolution;

@interface UIDevice (Resolutions)

- (UIDeviceResolution)resolution;

NSString *NSStringFromResolution(UIDeviceResolution resolution);

@end

File UIDevice+Resolutions.m:

#import "UIDevice+Resolutions.h"

@implementation UIDevice (Resolutions)

- (UIDeviceResolution)resolution
{
    UIDeviceResolution resolution = UIDeviceResolution_Unknown;
    UIScreen *mainScreen = [UIScreen mainScreen];
    CGFloat scale = ([mainScreen respondsToSelector:@selector(scale)] ? mainScreen.scale : 1.0f);
    CGFloat pixelHeight = (CGRectGetHeight(mainScreen.bounds) * scale);

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if (scale == 2.0f) {
            if (pixelHeight == 960.0f)
                resolution = UIDeviceResolution_iPhoneRetina4;
            else if (pixelHeight == 1136.0f)
                resolution = UIDeviceResolution_iPhoneRetina5;

        } else if (scale == 1.0f && pixelHeight == 480.0f)
            resolution = UIDeviceResolution_iPhoneStandard;

    } else {
        if (scale == 2.0f && pixelHeight == 2048.0f) {
            resolution = UIDeviceResolution_iPadRetina;

        } else if (scale == 1.0f && pixelHeight == 1024.0f) {
            resolution = UIDeviceResolution_iPadStandard;
        }
    }

    return resolution;
 }

 @end

This is how you need to use this code.

1) Add the above UIDevice+Resolutions.h & UIDevice+Resolutions.m files to your project

2) Add the line #import "UIDevice+Resolutions.h" to your ViewController.m

3) Add this code to check what versions of device you are dealing with

int valueDevice = [[UIDevice currentDevice] resolution];

    NSLog(@"valueDevice: %d ...", valueDevice);

    if (valueDevice == 0)
    {
        //unknow device - you got me!
    }
    else if (valueDevice == 1)
    {
        //standard iphone 3GS and lower
    }
    else if (valueDevice == 2)
    {
        //iphone 4 & 4S
    }
    else if (valueDevice == 3)
    {
        //iphone 5
    }
    else if (valueDevice == 4)
    {
        //ipad 2
    }
    else if (valueDevice == 5)
    {
        //ipad 3 - retina display
    }

I found this page after doing some sample exercises and having the exact same puzzlement.

============== I went from this code as provide by the sample ===============

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

    Map wordMap = new HashMap();
    if (args.length > 0) {
        for (int i = 0; i < args.length; i++) {
            countWord(wordMap, args[i]);
        }
    } else {
        getWordFrequency(System.in, wordMap);
    }
    for (Iterator i = wordMap.entrySet().iterator(); i.hasNext();) {
        Map.Entry entry = (Map.Entry) i.next();
        System.out.println(entry.getKey() + " :\t" + entry.getValue());
    }

====================== To This code ========================

public static void main(String[] args) throws IOException {
    // replace with TreeMap to get them sorted by name
    Map<String, Integer> wordMap = new HashMap<String, Integer>();
    if (args.length > 0) {
        for (int i = 0; i < args.length; i++) {
            countWord(wordMap, args[i]);
        }
    } else {
        getWordFrequency(System.in, wordMap);
    }
    for (Iterator<Entry<String, Integer>> i = wordMap.entrySet().iterator(); i.hasNext();) {
        Entry<String, Integer> entry =   i.next();
        System.out.println(entry.getKey() + " :\t" + entry.getValue());
    }

}

It may be safer but took 4 hours to demuddle the philosophy...

Yes:

Another good way to serialize json into c# is below:

RootObject ro = new RootObject();
     try
    {

        StreamReader sr = new StreamReader(FileLoc);
        string jsonString = sr.ReadToEnd();
        JavaScriptSerializer ser = new JavaScriptSerializer();
        ro = ser.Deserialize<RootObject>(jsonString);


   }

you need to add a reference to system.web.extensions in .net 4.0 this is in program files (x86) > reference assemblies> framework> system.web.extensions.dll and you need to be sure you're using just regular 4.0 framework not 4.0 client

Answer:

Your traceback is telling you that int() takes integers, you are trying to give a decimal, so you need to use float():

a = float(a)

This should work as expected:

>>> int(input("Type a number: "))
Type a number: 0.3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '0.3'
>>> float(input("Type a number: "))
Type a number: 0.3
0.3

Computers store numbers in a variety of different ways. Python has two main ones. Integers, which store whole numbers (Z), and floating point numbers, which store real numbers (R). You need to use the right one based on what you require.

(As a note, Python is pretty good at abstracting this away from you, most other language also have double precision floating point numbers, for instance, but you don't need to worry about that. Since 3.0, Python will also automatically convert integers to floats if you divide them, so it's actually very easy to work with.)

Previous guess at answer before we had the traceback:

Your problem is that whatever you are typing is can't be converted into a number. This could be caused by a lot of things, for example:

>>> int(input("Type a number: "))
Type a number: -1
-1
>>> int(input("Type a number: "))
Type a number: - 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '- 1'

Adding a space between the - and 1 will cause the string not to be parsed correctly into a number. This is, of course, just an example, and you will have to tell us what input you are giving for us to be able to say for sure what the issue is.

Advice on code style:

y = [int(a)**(-2),int(a)**(-1.75),int(a)**(-1.5),int(a)**(-1.25),
            int(a)**(-1),int(a)**(-0.75),int(a)**(-0.5),int(a)**(-0.25),
            int(a)**(0),int(a)**(0.25),int(a)**(0.5),int(a)**(0.75),
            int(a)**1,int(a)**(1.25),int(a)**(1.5),int(a)**(1.75), int(a)**(2)]

This is an example of a really bad coding habit. Where you are copying something again and again something is wrong. Firstly, you use int(a) a ton of times, wherever you do this, you should instead assign the value to a variable, and use that instead, avoiding typing (and forcing the computer to calculate) the value again and again:

a = int(a)

In this example I assign the value back to a, overwriting the old value with the new one we want to use.

y = [a**i for i in x]

This code produces the same result as the monster above, without the masses of writing out the same thing again and again. It's a simple list comprehension. This also means that if you edit x, you don't need to do anything to y, it will naturally update to suit.

Also note that PEP-8, the Python style guide, suggests strongly that you don't leave spaces between an identifier and the brackets when making a function call.

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

print(datetime.strftime('%b %d,%Y'))

Remove constraint not null to null

ALTER TABLE 'test' CHANGE COLUMN 'testColumn' 'testColumn' datatype NULL;

It is interesting but as for me help this:

 File -> Setting -> Gradle -> disable offline work

I've got a really simple chat example as part of slosh.

Edit: (since everyone's pasting their code in here)

This is the complete JSON-based multi-user chat using long-polling and slosh. This is a demo of how to do the calls, so please ignore the XSS problems. Nobody should deploy this without sanitizing it first.

Notice that the client always has a connection to the server, and as soon as anyone sends a message, everyone should see it roughly instantly.

For python 3

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)

You need to specify the minimum width of the field.

String.format("%" + numberOfSpaces + "s", ""); 

Why do you want to generate a String of spaces of a certain length.

If you want a column of this length with values then you can do:

String.format("%" + numberOfSpaces + "s", "Hello"); 

which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

Old post but this is exactly what I needed, simple question, how to change it to count column rather than Row. Thankyou in advance. Novice to Excel.

=SUM(A1:INDIRECT(CONCATENATE("A",C5)))

I.e My data is A1 B1 C1 D1 etc rather then A1 A2 A3 A4.

Firstly, the Instagram API endpoint "tags" required OAuth authentication.

You can query results for a particular hashtag (snowy in this case) using the following url

It is rate limited to 5000 (X-Ratelimit-Limit:5000) per hour

You can play around here :

You need to use "Authentication" as OAuth 2 and will be prompted to signin via Instagram. Post that you might have to reneter the "tag-name" in "Template" section.

All the pagination related data is available in the "pagination" parameter in the response and use it's "next_url" to query for the next set of result.

As of Django 1.10, the patterns module has been removed (it had been deprecated since 1.8).

Luckily, it should be a simple edit to remove the offending code, since the urlpatterns should now be stored in a plain-old list:

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    # ... your url patterns
]

Process GET parameters

The <f:viewParam> manages the setting, conversion and validation of GET parameters. It's like the <h:inputText>, but then for GET parameters.

The following example

<f:metadata>
    <f:viewParam name="id" value="#{bean.id}" />
</f:metadata>

does basically the following:

• Get the request parameter value by name id.
• Convert and validate it if necessary (you can use required, validator and converter attributes and nest a <f:converter> and <f:validator> in it like as with <h:inputText>)
• If conversion and validation succeeds, then set it as a bean property represented by #{bean.id} value, or if the value attribute is absent, then set it as request attribtue on name id so that it's available by #{id} in the view.

So when you open the page as foo.xhtml?id=10 then the parameter value 10 get set in the bean this way, right before the view is rendered.

As to validation, the following example sets the param to required="true" and allows only values between 10 and 20. Any validation failure will result in a message being displayed.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
</f:metadata>
<h:message for="id" />

Performing business action on GET parameters

You can use the <f:viewAction> for this.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
    <f:viewAction action="#{bean.onload}" />
</f:metadata>
<h:message for="id" />

with

public void onload() {
    // ...
}

The <f:viewAction> is however new since JSF 2.2 (the <f:viewParam> already exists since JSF 2.0). If you can't upgrade, then your best bet is using <f:event> instead.

<f:event type="preRenderView" listener="#{bean.onload}" />

This is however invoked on every request. You need to explicitly check if the request isn't a postback:

public void onload() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // ...
    }
}

When you would like to skip "Conversion/Validation failed" cases as well, then do as follows:

public void onload() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.isPostback() && !facesContext.isValidationFailed()) {
        // ...
    }
}

Using <f:event> this way is in essence a workaround/hack, that's exactly why the <f:viewAction> was introduced in JSF 2.2.

Pass view parameters to next view

You can "pass-through" the view parameters in navigation links by setting includeViewParams attribute to true or by adding includeViewParams=true request parameter.

<h:link outcome="next" includeViewParams="true">
<!-- Or -->
<h:link outcome="next?includeViewParams=true">

which generates with the above <f:metadata> example basically the following link

<a href="next.xhtml?id=10">

with the original parameter value.

This approach only requires that next.xhtml has also a <f:viewParam> on the very same parameter, otherwise it won't be passed through.

Use GET forms in JSF

The <f:viewParam> can also be used in combination with "plain HTML" GET forms.

<f:metadata>
    <f:viewParam id="query" name="query" value="#{bean.query}" />
    <f:viewAction action="#{bean.search}" />
</f:metadata>
...
<form>
    <label for="query">Query</label>
    <input type="text" name="query" value="#{empty bean.query ? param.query : bean.query}" />
    <input type="submit" value="Search" />
    <h:message for="query" />
</form>
...
<h:dataTable value="#{bean.results}" var="result" rendered="#{not empty bean.results}">
     ...
</h:dataTable>

With basically this @RequestScoped bean:

private String query;
private List<Result> results;

public void search() {
    results = service.search(query);
}

Note that the <h:message> is for the <f:viewParam>, not the plain HTML <input type="text">! Also note that the input value displays #{param.query} when #{bean.query} is empty, because the submitted value would otherwise not show up at all when there's a validation or conversion error. Please note that this construct is invalid for JSF input components (it is doing that "under the covers" already).

• ViewParam vs @ManagedProperty(value = "#{param.id}")

I have the same problem. I noticed from the git web page that the SSH clone URL have the next structure:

[email protected]:user/project.git

I could resolve my problem just changing the ":" by "/", as follows:

[email protected]/user/project.git

may be this can be helpful.

Another approach to add the class to element using pure JavaScript

For adding class:

document.getElementById("div1").classList.add("classToBeAdded");

For removing class:

document.getElementById("div1").classList.remove("classToBeRemoved");

Note: but not supported in IE <= 9 or Safari <=5.0

I had some problem getting the other examples to work.

EPPlus and other libraries produces OpenDocument Xml format, which is not the same as you get when you save from Excel as xlsx.

macks example with open CSV and just re-saving didn't work, I never managed to get the ',' delimiter to be used correctly.

Ansgar Wiechers example has some slight error which I found the answer for in the commencts.

Anyway, this is a complete working example. Save this in a File CsvToExcel.ps1

param (
[Parameter(Mandatory=$true)][string]$inputfile,
[Parameter(Mandatory=$true)][string]$outputfile
)

$excel = New-Object -ComObject Excel.Application
$excel.Visible = $false

$wb = $excel.Workbooks.Add()
$ws = $wb.Sheets.Item(1)

$ws.Cells.NumberFormat = "@"

write-output "Opening $inputfile"

$i = 1
Import-Csv $inputfile | Foreach-Object { 
    $j = 1
    foreach ($prop in $_.PSObject.Properties)
    {
        if ($i -eq 1) {
            $ws.Cells.Item($i, $j) = $prop.Name
        } else {
            $ws.Cells.Item($i, $j) = $prop.Value
        }
        $j++
    }
    $i++
}

$wb.SaveAs($outputfile,51)
$wb.Close()
$excel.Quit()
write-output "Success"

Execute with:

.\CsvToExcel.ps1 -inputfile "C:\Temp\X\data.csv" -outputfile "C:\Temp\X\data.xlsx"

Another option is to set the control param ClientID="Static" in .net and then you can access the object in JQuery by the ID you set.

Yes when i try it with View it provides the result of 25px. Here is the whole code :

public class SpinActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout lySpin = new LinearLayout(this);
        lySpin.setOrientation(LinearLayout.VERTICAL);       
        lySpin.post(new Runnable()
        {
            public void run()
            {
                Rect rect = new Rect();
                Window window = getWindow();
                window.getDecorView().getWindowVisibleDisplayFrame(rect);
                int statusBarHeight = rect.top;
                int contentViewTop = 
                    window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
                int titleBarHeight = contentViewTop - statusBarHeight;
                System.out.println("TitleBarHeight: " + titleBarHeight 
                    + ", StatusBarHeight: " + statusBarHeight);
            }
        }
    }
}

SELECT id, user_id, video_name
FROM sa_created_videos
ORDER BY LENGTH(id) ASC, LENGTH(user_id) DESC

This is for longs, but you can modify it easily to work with ints.

private static long[] ConvertStringArrayToLongArray(string str)
{
    return str.Split(",".ToCharArray()).Select(x => long.Parse(x.ToString())).ToArray();
}

I realise this is an old post, but in case it helps, you can apply this CSS to have IE11 draw a dotted outline for the focus indication of a <select> element so that it resembles Firefox's focus indication: select:focus::-ms-value { background: transparent; color: inherit; outline-style: dotted; outline-width: thin; }

each passes into your function index and element. Check index against the length of the set and you're good to go:

var set = $('.requiredText');
var length = set.length;
set.each(function(index, element) {
      thisVal = $(this).val();
      if(parseInt(thisVal) !== 0) {
          console.log('Valid Field: ' + thisVal);
          if (index === (length - 1)) {
              console.log('Last field, submit form here');
          }
      }
});

You can try adding action="#{yourBean.function1}" on each button (changing of course the method function2, function3, or whatever you need). If that does not work, you can try the same with the onclick event.

Anyway, it would be easier to help you if you tell us what kind of buttons are you trying to use, a4j:commandButton or whatever you are using.

to get the last value from a column you can also use MAX function with IF function

=ARRAYFORMULA(INDIRECT("G"&MAX(IF(G:G<>"", ROW(G:G), )), 4)))

Actually it's way easier to use ToolBucket plugin for Notepad++ to multiline replace.

To activate it just go to N++ menu:

Plugins > Plugin Manager > Show Plugin Manager > Check ToolBucket > Install.

Restart N++ and press ALT + SHIFT + F to multiline edit.

Try with:

@Scheduled(cron = "0 1 1 * * ?")

Below you can find the example patterns from the spring forum:

* "0 0 * * * *" = the top of every hour of every day.
* "*/10 * * * * *" = every ten seconds.
* "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
* "0 0 8,10 * * *" = 8 and 10 o'clock of every day.
* "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30 and 10 o'clock every day.
* "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
* "0 0 0 25 12 ?" = every Christmas Day at midnight

Cron expression is represented by six fields:

second, minute, hour, day of month, month, day(s) of week

(*) means match any

*/X means "every X"

? ("no specific value") - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but I don't care what day of the week that happens to be, I would put "10" in the day-of-month field and "?" in the day-of-week field.

PS: In order to make it work, remember to enable it in your application context: https://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/scheduling.html#scheduling-annotation-support

We can use the rank() window function (where you would choose the rank = 1) rank just adds a number for every row of a group (in this case it would be the hour)

here's an example. ( from https://github.com/jaceklaskowski/mastering-apache-spark-book/blob/master/spark-sql-functions.adoc#rank )

val dataset = spark.range(9).withColumn("bucket", 'id % 3)

import org.apache.spark.sql.expressions.Window
val byBucket = Window.partitionBy('bucket).orderBy('id)

scala> dataset.withColumn("rank", rank over byBucket).show
+---+------+----+
| id|bucket|rank|
+---+------+----+
|  0|     0|   1|
|  3|     0|   2|
|  6|     0|   3|
|  1|     1|   1|
|  4|     1|   2|
|  7|     1|   3|
|  2|     2|   1|
|  5|     2|   2|
|  8|     2|   3|
+---+------+----+

some background info on this:

Some changes in libpng version 1.6+ cause it to issue a warning or even not work correctly with the original HP/MS sRGB profile, leading to the following stderr: libpng warning: iCCP: known incorrect sRGB profile The old profile uses a D50 whitepoint, where D65 is standard. This profile is not uncommon, being used by Adobe Photoshop, although it was not embedded into images by default.

(source: https://wiki.archlinux.org/index.php/Libpng_errors)

Error detection in some chunks has improved; in particular the iCCP chunk reader now does pretty complete validation of the basic format. Some bad profiles that were previously accepted are now rejected, in particular the very old broken Microsoft/HP sRGB profile. The PNG spec requirement that only grayscale profiles may appear in images with color type 0 or 4 and that even if the image only contains gray pixels, only RGB profiles may appear in images with color type 2, 3, or 6, is now enforced. The sRGB chunk is allowed to appear in images with any color type.

The plus-symbol in a circle does not denote addition. It is a XOR operation.

If you want to see the default browser errors being displayed, for example, those triggered by HTML attributes (showing up before any client-code JS treatment):

<input name="o" required="required" aria-required="true" type="text">

You should use the submit event instead of the click event. In this case a popup will be automatically displayed requesting "Please fill out this field". Even with preventDefault:

$('form').on('submit', function(event) {
   event.preventDefault();
   my_form_treatment(this, event);
}); // -> this will show up a "Please fill out this field" pop-up before my_form_treatment

As someone mentioned previously, return false would stop propagation (i.e. if there are more handlers attached to the form submission, they would not be executed), but, in this case, the action triggered by the browser will always execute first. Even with a return false at the end.

So if you want to get rid of these default pop-ups, use the click event on the submit button:

$('form input[type=submit]').on('click', function(event) {
   event.preventDefault();
   my_form_treatment(this, event);
}); // -> this will NOT show any popups related to HTML attributes

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

Save the file. For this example, the file will be named C:\mysql-init.txt. it asking administrative permisions for saving the file

Every enum has both a name() and a valueOf(String) method. The former returns the string name of the enum, and the latter gives the enum value whose name is the string. Is this like what you're looking for?

String name = Modes.mode1.name();
Modes mode = Modes.valueOf(name);

There's also a static valueOf(Class, String) on Enum itself, so you could also use

Modes mode = Enum.valueOf(Modes.class, name);

IF you have NOT pushed your changes to remote

git reset HEAD~1

Check if the working copy is clean by git status.

ELSE you have pushed your changes to remote

git revert HEAD

This command will revert/remove the local commits/change and then you can push

This is same as the previous solution but I have defined the function in df.apply itself:

df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

The precision of float is 7 digits. If you want to keep the whole lot, you need to use the double type that keeps 15-16 digits. Regarding formatting, look at a post about formatting doubles. And you need to worry about decimal separators in C#.

Another alternative would be JasperReports: JasperReports Library. It uses iText itself and is more than a PDF library you asked for, but if it fits your needs I'd go for it.

Simply put, it allows you to design reports that can be filled during runtime. If you use a custom datasource, you might be able to integrate JasperReports easily into the existing system. It would save you the whole layouting troubles, e.g. when invoices span over more sites where each side should have a footer and so on.

If you are just targeting specific domains you can try and add this in your application's Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>example.com</key>
        <dict>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

In your XML set the Background attribute to any colour, White(#FFFFFF) shade or Black(#000000) shade. If you want transparency, just put 80 before the actual hash code:

#80000000

This will change any colour you want to a transparent one.. :)

java.time

In Java 8 and later, we have the java.time framework built into Java 8 and later. These new classes supplant the troublesome old java.util.Date/.Calendar classes. The new classes are inspired by the highly successful Joda-Time framework, intended as its successor, similar in concept but re-architected. Defined by JSR 310. Extended by the ThreeTen-Extra project. See the Tutorial.

Be aware that java.time is capable of nanosecond resolution (9 decimal places in fraction of second), versus the millisecond resolution (3 decimal places) of both java.util.Date & Joda-Time. So when formatting to display only 3 decimal places, you could be hiding data.

If you want to eliminate any microseconds or nanoseconds from your data, truncate.

Instant instant2 = instant.truncatedTo( ChronoUnit.MILLIS ) ;

The java.time classes use ISO 8601 format by default when parsing/generating strings. A Z at the end is short for Zulu, and means UTC.

An Instant represents a moment on the timeline in UTC with resolution of up to nanoseconds. Capturing the current moment in Java 8 is limited to milliseconds, with a new implementation in Java 9 capturing up to nanoseconds depending on your computer’s hardware clock’s abilities.

Instant instant = Instant.now (); // Current date-time in UTC.
String output = instant.toString ();

2016-05-06T23:24:25.694Z

Replace the T in the middle with a space, and the Z with nothing, to get your desired output.

String output = instant.toString ().replace ( "T" , " " ).replace( "Z" , "" ; // Replace 'T', delete 'Z'. I recommend leaving the `Z` or any other such [offset-from-UTC][7] or [time zone][7] indicator to make the meaning clear, but your choice of course.

2016-05-06 23:24:25.694

As you don't care about including the offset or time zone, make a "local" date-time unrelated to any particular locality.

String output = LocalDateTime.now ( ).toString ().replace ( "T", " " );

Joda-Time

The highly successful Joda-Time library was the inspiration for the java.time framework. Advisable to migrate to java.time when convenient.

The ISO 8601 format includes milliseconds, and is the default for the Joda-Time 2.4 library.

System.out.println( "Now: " + new DateTime ( DateTimeZone.UTC ) );

When run…

Now: 2013-11-26T20:25:12.014Z

Also, you can ask for the milliseconds fraction-of-a-second as a number, if needed:

int millisOfSecond = myDateTime.getMillisOfSecond ();

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

It's pretty user friendly. Just work with NSFileManager's defaultManager singleton and then use the fileExistsAtPath() method, which simply takes a string as an argument, and returns a Bool, allowing it to be placed directly in the if statement.

let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let documentDirectory = paths[0] as! String
let myFilePath = documentDirectory.stringByAppendingPathComponent("nameOfMyFile")

let manager = NSFileManager.defaultManager()
if (manager.fileExistsAtPath(myFilePath)) {
    // it's here!!
}

Note that the downcast to String isn't necessary in Swift 2.

For me, it worked to use Newtonsoft.Json:

using Newtonsoft.Json;
// ...
var output = JsonConvert.SerializeObject(ListOfMyObject);

Using only .length is not safe and will cause an error in some browsers. Here is a better solution:

if(array && array.length){   
   // not empty 
} else {
   // empty
}

or, we can use:

Object.keys(__array__).length

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.

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

One easy solution is to use delayed expansion, as this doesn't change any special characters.

set "line=<?xml version="1.0" encoding="utf-8" ?>"
setlocal EnableDelayedExpansion
(
  echo !line!
) > myfile.xml

EDIT : Another solution is to use a disappearing quote.

This technic uses a quotation mark to quote the special characters

@echo off
setlocal EnableDelayedExpansion
set ""="
echo !"!<?xml version="1.0" encoding="utf-8" ?>

The trick works, as in the special characters phase the leading quotation mark in !"! will preserve the rest of the line (if there aren't other quotes).
And in the delayed expansion phase the !"! will replaced with the content of the variable " (a single quote is a legal name!).

If you are working with disabled delayed expansion, you could use a FOR /F loop instead.

for /f %%^" in ("""") do echo(%%~" <?xml version="1.0" encoding="utf-8" ?>

But as the seems to be a bit annoying you could also build a macro.

set "print=for /f %%^" in ("""") do echo(%%~""

%print%<?xml version="1.0" encoding="utf-8" ?>
%print% Special characters like &|<>^ works now without escaping

I needed to do the same and had to query a query to get the result

I set my first query up to bring in all IDs from the table and all other information needed to filter:

SELECT tMAIN.tLOTS.NoContract, tMAIN.ID
FROM tMAIN INNER JOIN tLOTS ON tMAIN.ID = tLOTS.id
WHERE (((tLOTS.NoContract)=False));

Save this as Q04_1 -0 this returned 1229 results (there are 63 unique records to query - soime with multiple LOTs)

SELECT DISTINCT ID
FROM q04_1;

Saved that as q04_2

I then wrote another query which brought in the required information linked to the ID

SELECT q04_2.ID, tMAIN.Customer, tMAIN.Category
FROM q04_2 INNER JOIN tMAIN ON q04_2.ID = tMAIN.ID;

Worked a treat and got me exactly what I needed - 63 unique records returned with customer and category details.

This is how I worked around it as I couldn't get the Group By working at all - although I am rather "wet behind the ears" weith SQL (so please be gentle and constructive with feedback)

In servers, you may like to send RST instead of FIN when disconnecting misbehaving clients. That skips FIN-WAIT followed by TIME-WAIT socket states in the server, which prevents from depleting server resources, and, hence, protects from this kind of denial-of-service attack.

Yes, a static class for storing constants would be just fine, except for constants that are related to specific types.

I've heard that Geocoder is on the buggy side. I recently put together an example application that uses Google's http geocoding service to lookup location from lat/long. Feel free to check it out here

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.

Julen solution is kind of hard to read, here's clearer and to-the-point react code for anyone who stumbled him based on title and not the tiny details of the question.

tl;dr version: when you would update to observers send call a schedule method instead and that in turn will actually notify the observers (or perform ajax, etc)

JLS

JLS 7 3.10.5 defines it and gives a practical example:

Moreover, a string literal always refers to the same instance of class String. This is because string literals - or, more generally, strings that are the values of constant expressions (§15.28) - are "interned" so as to share unique instances, using the method String.intern.

Example 3.10.5-1. String Literals

The program consisting of the compilation unit (§7.3):

package testPackage;
class Test {
    public static void main(String[] args) {
        String hello = "Hello", lo = "lo";
        System.out.print((hello == "Hello") + " ");
        System.out.print((Other.hello == hello) + " ");
        System.out.print((other.Other.hello == hello) + " ");
        System.out.print((hello == ("Hel"+"lo")) + " ");
        System.out.print((hello == ("Hel"+lo)) + " ");
        System.out.println(hello == ("Hel"+lo).intern());
    }
}
class Other { static String hello = "Hello"; }

and the compilation unit:

package other;
public class Other { public static String hello = "Hello"; }

produces the output:

true true true true false true

JVMS

JVMS 7 5.1 says says that interning is implemented magically and efficiently with a dedicated CONSTANT_String_info struct (unlike most other objects which have more generic representations):

A string literal is a reference to an instance of class String, and is derived from a CONSTANT_String_info structure (§4.4.3) in the binary representation of a class or interface. The CONSTANT_String_info structure gives the sequence of Unicode code points constituting the string literal.

The Java programming language requires that identical string literals (that is, literals that contain the same sequence of code points) must refer to the same instance of class String (JLS §3.10.5). In addition, if the method String.intern is called on any string, the result is a reference to the same class instance that would be returned if that string appeared as a literal. Thus, the following expression must have the value true:

("a" + "b" + "c").intern() == "abc"

To derive a string literal, the Java Virtual Machine examines the sequence of code points given by the CONSTANT_String_info structure.

• If the method String.intern has previously been called on an instance of class String containing a sequence of Unicode code points identical to that given by the CONSTANT_String_info structure, then the result of string literal derivation is a reference to that same instance of class String.

• Otherwise, a new instance of class String is created containing the sequence of Unicode code points given by the CONSTANT_String_info structure; a reference to that class instance is the result of string literal derivation. Finally, the intern method of the new String instance is invoked.

Bytecode

Let's decompile some OpenJDK 7 bytecode to see interning in action.

If we decompile:

public class StringPool {
    public static void main(String[] args) {
        String a = "abc";
        String b = "abc";
        String c = new String("abc");
        System.out.println(a);
        System.out.println(b);
        System.out.println(a == c);
    }
}

we have on the constant pool:

#2 = String             #32   // abc
[...]
#32 = Utf8               abc

and main:

 0: ldc           #2          // String abc
 2: astore_1
 3: ldc           #2          // String abc
 5: astore_2
 6: new           #3          // class java/lang/String
 9: dup
10: ldc           #2          // String abc
12: invokespecial #4          // Method java/lang/String."<init>":(Ljava/lang/String;)V
15: astore_3
16: getstatic     #5          // Field java/lang/System.out:Ljava/io/PrintStream;
19: aload_1
20: invokevirtual #6          // Method java/io/PrintStream.println:(Ljava/lang/String;)V
23: getstatic     #5          // Field java/lang/System.out:Ljava/io/PrintStream;
26: aload_2
27: invokevirtual #6          // Method java/io/PrintStream.println:(Ljava/lang/String;)V
30: getstatic     #5          // Field java/lang/System.out:Ljava/io/PrintStream;
33: aload_1
34: aload_3
35: if_acmpne     42
38: iconst_1
39: goto          43
42: iconst_0
43: invokevirtual #7          // Method java/io/PrintStream.println:(Z)V

Note how:

• 0 and 3: the same ldc #2 constant is loaded (the literals)
• 12: a new string instance is created (with #2 as argument)
• 35: a and c are compared as regular objects with if_acmpne

The representation of constant strings is quite magic on the bytecode:

• it has a dedicated CONSTANT_String_info structure, unlike regular objects (e.g. new String)
• the struct points to a CONSTANT_Utf8_info Structure that contains the data. That is the only necessary data to represent the string.

and the JVMS quote above seems to say that whenever the Utf8 pointed to is the same, then identical instances are loaded by ldc.

I have done similar tests for fields, and:

• static final String s = "abc" points to the constant table through the ConstantValue Attribute
• non-final fields don't have that attribute, but can still be initialized with ldc

Conclusion: there is direct bytecode support for the string pool, and the memory representation is efficient.

Bonus: compare that to the Integer pool, which does not have direct bytecode support (i.e. no CONSTANT_String_info analogue).

A way for integers without banal converting to string:

var num = 9999999999; // your number
var length = 1;
while (num >= 10) {
   num /= 10;
   length++;
}
alert(length);

This will do it for you:

=IF(OR(ISNUMBER(SEARCH("Gingrich",C3)),ISNUMBER(SEARCH("Obama",C3))),"1","")

Given this function in the column to the right of the names (which are in column C), the result is:

Romney  
Gingrich    1
Obama       1

Project is not a statement. It is the capability of the select statement. Select statement has three capabilities. They are selection,projection,join. Selection-it retrieves the rows that are satisfied by the given query. Projection-it chooses the columns that are satisfied by the given query. Join-it joins the two or more tables

Don't worry about you should just change .dll from x64 to x86, in the native library.

for example:- you might have selected this (C:\opencv\build\java\x64).

instead you select this for native library(C:\opencv\build\java\x86).

json.dump() will preserve the ordder of your dictionary. Open the file in a text editor and you will see. It will preserve the order regardless of whether you send it an OrderedDict.

But json.load() will lose the order of the saved object unless you tell it to load into an OrderedDict(), which is done with the object_pairs_hook parameter as J.F.Sebastian instructed above.

It would otherwise lose the order because under usual operation, it loads the saved dictionary object into a regular dict and a regular dict does not preserve the oder of the items it is given.

You cannot (except the type of a particular iterator implements some specific methods that make it possible).

Generally, you may count iterator items only by consuming the iterator. One of probably the most efficient ways:

import itertools
from collections import deque

def count_iter_items(iterable):
    """
    Consume an iterable not reading it into memory; return the number of items.
    """
    counter = itertools.count()
    deque(itertools.izip(iterable, counter), maxlen=0)  # (consume at C speed)
    return next(counter)

(For Python 3.x replace itertools.izip with zip).

only use:

cout << dec << 0x;

If anybody encounters this with errors like Error: cannot add duplicate collection entry of type ‘mimeMap’ with unique key attribute and/or other scripts stop working when doing this fix, it might help to remove it first like this:

<staticContent>
  <remove fileExtension=".woff" />
  <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
</staticContent>

At least that solved my problem

I had a similar problem on Windows using Git Bash. I kept getting this error when trying to do a git clone. The repository was on a Linux box with GitLab installed.

git clone git@servername:path/to/repo
fatal: protocol error: bad line length character: git@

I made sure the ssh key was generated. The public key was added on GitLab. The ssh-agent was running and the generated key was added (github link).

I ran out of options and then finally tried closing Git Bash and opening it again by right clicking 'Run as Administrator'. Worked after that.

If you use .NET as your middle tier, check the route attribute clearly, for example,

I had issue when it was like this,

[Route("something/{somethingLong: long}")] //Space.

Fixed it by this,

[Route("something/{somethingLong:long}")] //No space

Change key in Project > Build Setting "typecheck calls to printf/scanf : NO"

Explanation : [How it works]

Check calls to printf and scanf, etc., to make sure that the arguments supplied have types appropriate to the format string specified, and that the conversions specified in the format string make sense.

Hope it work

Seems the answer(s) to this question are outdated with the release of Java 8.

1. Don't use ordinal as ordinal is unstable if persisted outside the JVM such as a database.
2. It is relatively easy to create a static map with the key values.

public enum AccessLevel {
  PRIVATE("private", 0),
  PUBLIC("public", 1),
  DEFAULT("default", 2);

  AccessLevel(final String name, final int value) {
    this.name = name;
    this.value = value;
  }

  private final String name;
  private final int value;

  public String getName() {
    return name;
  }

  public int getValue() {
    return value;
  }

  static final Map<String, AccessLevel> names = Arrays.stream(AccessLevel.values())
      .collect(Collectors.toMap(AccessLevel::getName, Function.identity()));
  static final Map<Integer, AccessLevel> values = Arrays.stream(AccessLevel.values())
      .collect(Collectors.toMap(AccessLevel::getValue, Function.identity()));

  public static AccessLevel fromName(final String name) {
    return names.get(name);
  }

  public static AccessLevel fromValue(final int value) {
    return values.get(value);
  }
}

Swift 5: The Codable protocol can be used instead of NSKeyedArchiever.

struct User: Codable {
    let id: String
    let mail: String
    let fullName: String
}

The Pref struct is custom wrapper around the UserDefaults standard object.

struct Pref {
    static let keyUser = "Pref.User"
    static var user: User? {
        get {
            if let data = UserDefaults.standard.object(forKey: keyUser) as? Data {
                do {
                    return try JSONDecoder().decode(User.self, from: data)
                } catch {
                    print("Error while decoding user data")
                }
            }
            return nil
        }
        set {
            if let newValue = newValue {
                do {
                    let data = try JSONEncoder().encode(newValue)
                    UserDefaults.standard.set(data, forKey: keyUser)
                } catch {
                    print("Error while encoding user data")
                }
            } else {
                UserDefaults.standard.removeObject(forKey: keyUser)
            }
        }
    }
}

So you can use it this way:

Pref.user?.name = "John"

if let user = Pref.user {...

SELECT count(*)
FROM information_schema.columns
WHERE table_name = 'tbl_ifo'

All the answers above are great. Only one thing is missing, be sure to drag the grey buttons to see the table (step number 2):

Your hack of decrementing the count at the end is exactly that -- a hack.

Far better to write your loop correctly in the first place, so it doesn't count the last line twice.

int main() { 
    int number_of_lines = 0;
    std::string line;
    std::ifstream myfile("textexample.txt");

    while (std::getline(myfile, line))
        ++number_of_lines;
    std::cout << "Number of lines in text file: " << number_of_lines;
    return 0;
}

Personally, I think in this case, C-style code is perfectly acceptable:

int main() {
    unsigned int number_of_lines = 0;
    FILE *infile = fopen("textexample.txt", "r");
    int ch;

    while (EOF != (ch=getc(infile)))
        if ('\n' == ch)
            ++number_of_lines;
    printf("%u\n", number_of_lines);
    return 0;
}

Edit: Of course, C++ will also let you do something a bit similar:

int main() {
    std::ifstream myfile("textexample.txt");

    // new lines will be skipped unless we stop it from happening:    
    myfile.unsetf(std::ios_base::skipws);

    // count the newlines with an algorithm specialized for counting:
    unsigned line_count = std::count(
        std::istream_iterator<char>(myfile),
        std::istream_iterator<char>(), 
        '\n');

    std::cout << "Lines: " << line_count << "\n";
    return 0;
}

The following shell script, perhaps?

#!/bin/sh
if [[ -e $1 ]]
then
  if [[ ! -d $2 ]]
  then
    mkdir --parents $2
  fi
fi
mv $1 $2

That's the basic part. You might want to add in a bit to check for arguments, and you may want the behavior to change if the destination exists, or the source directory exists, or doesn't exist (i.e. don't overwrite something that doesn't exist).

The quote PASV command is not a command to the ftp.exe program, it is a command to the FTP server requesting a high order port for data transfer. A passive transfer is one in which the FTP data over these high order ports while control is maintained in the lower ports.

The windows ftp.exe program can be used to send the FTP server commands to make a passive data transfer between two FTP servers. A standard windows installation will not, and probably should not, have FTP server service running as an endpoint for passive transfers. So if passive transfers are needed with a standard windows box, a solution other than ftp.exe is necessary as FTPing to localhost as one of the connections won't work in most windows environments.

You can effect a passive FTP transfer between two different hosts (but not two connections on the same host) as follows:

Open up two prompts, use one to ftp.exe connect to your source FTP server and one to ftp.exe connect to your destination FTP server.

Now establish a passive connection between the servers using the raw commands PASV and PORT. The quote PASV command will respond with an IP/port in ellipsis. Use that data for the quote PORT <data> command. Your passive link is now established assuming that firewalls haven't blocked one or more of the four ports (2 for FTP control, 2 for FTP data)

Next start receive of data with the quote STOR <filename> command to the receiving FTP server then send the control command quote RETR <filename> to the source FTP server.

so for me:

client 1
> ftp.exe server1
ftp> quote PASV
227 Entering Passive Mode (10,0,3,1,54,161)

client 2 
> ftp.exe server2
ftp> quote PORT 10,0,3,1,54,54,161
ftp> quote STOR myFile

client 1
ftp> quote RETR myFile

Cavet: I'm connecting to some old FTP servers YMMV

setInterval sets up a recurring timer. It returns a handle that you can pass into clearInterval to stop it from firing:

var handle = setInterval(drawAll, 20);

// When you want to cancel it:
clearInterval(handle);
handle = 0; // I just do this so I know I've cleared the interval

On browsers, the handle is guaranteed to be a number that isn't equal to 0; therefore, 0 makes a handy flag value for "no timer set". (Other platforms may return other values; NodeJS's timer functions return an object, for instance.)

To schedule a function to only fire once, use setTimeout instead. It won't keep firing. (It also returns a handle you can use to cancel it via clearTimeout before it fires that one time if appropriate.)

setTimeout(drawAll, 20);

One solution is with JQuery:

$(document).ready(
    function () {
        $('#mycheckboxId').click(function () {
               // here the action or function to call
        });
    }
);

It's possible to use a udev rule to let the system decide on the scheduler based on some characteristics of the hw.
An example udev rule for SSDs and other non-rotational drives might look like

# set noop scheduler for non-rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="noop"

inside a new udev rules file (e.g., /etc/udev/rules.d/60-ssd-scheduler.rules). This answer is based on the debian wiki

To check whether ssd disks would use the rule, it's possible to check for the trigger attribute in advance:

for f in /sys/block/sd?/queue/rotational; do printf "$f "; cat $f; done

If you use jquery:

$('head').append('<link rel="stylesheet" type="text/css" href="style.css">');

The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.

When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.

Extending on Bumptious Q Bangwhistle's answer:

$('#select2').append($('<option>', { 
    value: item,
    text : item 
})).select2();

This would add the new options into the <select> tags and lets select2 re-render it.

One of the elements to consider as you design your interface is on what event (when A takes place, B happens...) does the new checkbox end up being added?

Let's say there is a button next to the text box. When the button is clicked the value of the textbox is turned into a new checkbox. Our markup could resemble the following...

<div id="checkboxes">
    <input type="checkbox" /> Some label<br />
    <input type="checkbox" /> Some other label<br />
</div>

<input type="text" id="newCheckText" /> <button id="addCheckbox">Add Checkbox</button>

Based on this markup your jquery could bind to the click event of the button and manipulate the DOM.

$('#addCheckbox').click(function() {
    var text = $('#newCheckText').val();
    $('#checkboxes').append('<input type="checkbox" /> ' + text + '<br />');
});

You should not set ENV variables in package.json. actionhero uses NODE_ENV to allow you to change configuration options which are loaded from the files in ./config. Check out the redis config file, and see how NODE_ENV is uses to change database options in NODE_ENV=test

If you want to use other ENV variables to set things (perhaps the HTTP port), you still don't need to change anything in package.json. For example, if you set PORT=1234 in ENV and want to use that as the HTTP port in NODE_ENV=production, just reference that in the relevant config file, IE:

# in config/servers/web.js
exports.production = { 
  servers: {
    web: function(api){
      return {
       port: process.env.PORT
      }
    }
  }
}

>>> l = raw_input()
1 2 3 4 5 6 7 8 9 10
>>> l = l.split()
>>> l.pop(0)
'1'
>>> sum(map(int, l)) #or simply sum(int(x) for x in l) , you've to convert the elements to integer first, before applying sum()

To expound on darioo's answer with a concrete example. Tomcat 7 installed using homebrew on OS X, using Eclipse:

1. Right click your project folder, select Properties at the bottom of the context menu.
2. Select "Java Build Path"
3. Click Libraries" tab
4. Click "Add Library..." button on right (about halfway down)
5. Select "Server Runtime" click "Next"
6. Select your Tomcat version from the list
7. Click Finish

What? No Tomcat version is listed even though you have it installed via homebrew??

1. Switch to the Java EE perspective (top right)
2. In the "Window" menu select "Show View" -> "Servers"
3. In the Servers tab (typically at bottom) right click and select "New > Server"
4. Add the path to the homebrew tomcat installation in the dialog/wizard (something like: /usr/local/Cellar/tomcat/7.0.14/libexec)

Hope that helps someone who is just getting started out a little.

Implement Login for Devices

Facebook Login for Devices is for devices that directly make HTTP calls over the internet. The following are the API calls and responses your device can make.

1. Enable Login for Devices

Change Settings > Advanced > OAuth Settings > Login from Devices to 'Yes'.

2. Generate a Code which is required for facebook device identification

When the person clicks Log in with Facebook, you device should make an HTTP POST to:

POST https://graph.facebook.com/oauth/device?
       type=device_code
       &amp;client_id=<YOUR_APP_ID>
       &amp;scope=<COMMA_SEPARATED_PERMISSION_NAMES> // e.g.public_profile,user_likes

This response means:

• Display the string “A1NWZ9” on your device
• Tell the person to go to “facebook.com/device” and enter this code
• The code expires in 420 seconds. You should cancel the login flow after that time if you do not receive an access token
• Your device should poll the Device Login API every 5 seconds to see if the authorization has been successful

3. Display the Code

Your device should display the user_code and tell people to visit the verification_uri such as facebook.com/device on their PC or smartphone. See the Design Guidelines.

4. Poll for Authorization

Your device should poll the Device Login API to see if the person successfully authorized your application. You should do this at the interval in the response to your call in Step 1, which is every 5 seconds. Your device should poll to:

POST https://graph.facebook.com/oauth/device?
       type=device_token
       &amp;client_id=<YOUR_APP_ID> 
       &amp;code=<LONG_CODE_FROM_STEP_1> //e.g."92a2b2e351f2b0b3503b2de251132f47"

You will get 200 HTTP code i.e User has successfully authorized the device. The device can now use the access_token value to make authenticated API calls.

5. Confirm Successful Login

Your device should display their name and if available, a profile picture until they click Continue. To get the person's name and profile picture, your device should make a standard Graph API call:

GET https://graph.facebook.com/v2.3/me?
      fields=name,picture&
      access_token=<USER_ACCESS_TOKEN>

Response:

{
  "name": "John Doe", 
  "picture": {
    "data": {
      "is_silhouette": false, 
      "url": "https://fbcdn.akamaihd.net/hmac...ile.jpg"
    }
  }, 
  "id": "2023462875238472"
}

6. Store Access Tokens

Your device should persist the access token to make other requests to the Graph API.

Device Login access tokens may be valid for up to 60 days but may be invalided in a number of scenarios. For example when a person changes their Facebook password their access token is invalidated.

If the token is invalid, your device should delete the token from its memory. The person using your device needs to perform the Device Login flow again from Step 1 to retrieve a new, valid token.

I had same issue using different dependancy what helped me is to set scope to compile.

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>

    </dependency>

Use itext libray:

Here is the sample code. It is working perfectly fine:

        String htmlFilePath = filePath + ".html";
        String pdfFilePath = filePath + ".pdf";

        // create an html file on given file path
        Writer unicodeFileWriter = new OutputStreamWriter(new FileOutputStream(htmlFilePath), "UTF-8");
        unicodeFileWriter.write(document.toString());
        unicodeFileWriter.close();

        ConverterProperties properties = new ConverterProperties();
        properties.setCharset("UTF-8");
        if (url.contains(".kr") || url.contains(".tw") || url.contains(".cn") || url.contains(".jp")) {
            properties.setFontProvider(new DefaultFontProvider(false, false, true));
        }

        // convert the html file to pdf file.
        HtmlConverter.convertToPdf(new File(htmlFilePath), new File(pdfFilePath), properties);

So basically you want to find a file in mounted filesystem (not necessarily in PATH directories only) and check if it is executable. This translates to following plan:

• enumerate all files in locally mounted filesystems
• match results with name pattern
• for each file found check if it is executable

I'd say, doing this in a portable way will require lots of computing power and time. Is it really what you need?

I tried all the proposals to fix the render performance problem in my phonegap app. But nothing realy worked.

Finally, after a whole day of searching, I made it. I set within the tag (not the tag) of my AndroidManifest

<application android:hardwareAccelerated="false" ...

Now the app behaves in the same fast way as my webbrowser. Seems like, if hardware acceleration is not always the best feature...

The detailed problem I had: https://stackoverflow.com/a/24467920/3595386

Lets look at some test cases - try running the following expressions in your JS console:

"a" < "b"

"aa" < "ab"

"aaa" < "aab"

All return true.

JavaScript compares strings character by character and "a" comes before "b" in the alphabet - hence less than.

In your case it works like so -

1 . "a?aaa" < "?a?b"

compares the first two "a" characters - all equal, lets move to the next character.

2 . "a?a??aa" < "a?b??"

compares the second characters "a" against "b" - whoop! "a" comes before "b". Returns true.

I know this is a quite old question, but when you have JavaScript available you could use jQuery and its AJAX methods.

First, create a page with all the navigation bar's HTML content.

Next, use jQuery's $.get method to fetch the content of the page. For example, let's say you've put all the navigation bar's HTML into a file called navigation.html and added a placeholder tag (Like <div id="nav-placeholder">) in your index.html, then you would use the following code:

<script src="//code.jquery.com/jquery.min.js"></script>
<script>
$.get("navigation.html", function(data){
    $("#nav-placeholder").replaceWith(data);
});
</script>

git show <revhash>

Documentation here. Or if that doesn't work, try Google Code's GIT Documentation

first configure routing

import {RouteConfig, Router, ROUTER_DIRECTIVES} from 'angular2/router';

and

@RouteConfig([
  { path: '/addDisplay', component: AddDisplay, as: 'addDisplay' },
  { path: '/<secondComponent>', component: '<secondComponentName>', as: 'secondComponentAs' },
])

then in your component import and then inject Router

import {Router} from 'angular2/router'

export class AddDisplay {
  constructor(private router: Router)
}

the last thing you have to do is to call

this.router.navigateByUrl('<pathDefinedInRouteConfig>');

or

this.router.navigate(['<aliasInRouteConfig>']);

Please note that if you made changes to textarea, after it had rendered; You will get the updated value instead of the initialized value.

<!doctype html>
<html lang="en">
    <head>
        <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
        <script>
            $(function () {
                $('#btnShow').click(function () {
                    alert('text:' + $('#addressFieldName').text() + '\n value:' + $('#addressFieldName').val());
                });
            });
            function updateAddress() {
                $('#addressFieldName').val('District: Peshawar \n');
            }
        </script>
    </head>
    <body>
        <?php
        $address = "School: GCMHSS NO.1\nTehsil: ,\nDistrict: Haripur";
        ?>
        <textarea id="addressFieldName" rows="4" cols="40" tabindex="5" ><?php echo $address; ?></textarea>
        <?php echo '<script type="text/javascript">updateAddress();</script>'; ?>
        <input type="button" id="btnShow" value='show' />
    </body>
</html>

As you can see the value of textarea will be different than the text in between the opening and closing tag of concern textarea.

I think I get what you mean. Let's say for example you want the right-most \ in the following string (which is stored in cell A1):

Drive:\Folder\SubFolder\Filename.ext

To get the position of the last \, you would use this formula:

=FIND("@",SUBSTITUTE(A1,"\","@",(LEN(A1)-LEN(SUBSTITUTE(A1,"\","")))/LEN("\")))

That tells us the right-most \ is at character 24. It does this by looking for "@" and substituting the very last "\" with an "@". It determines the last one by using

(len(string)-len(substitute(string, substring, "")))\len(substring)

In this scenario, the substring is simply "\" which has a length of 1, so you could leave off the division at the end and just use:

=FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))

Now we can use that to get the folder path:

=LEFT(A1,FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\","")))))

Here's the folder path without the trailing \

=LEFT(A1,FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))-1)

And to get just the filename:

=MID(A1,FIND("@",SUBSTITUTE(A1,"\","@",LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))+1,LEN(A1))

However, here is an alternate version of getting everything to the right of the last instance of a specific character. So using our same example, this would also return the file name:

=TRIM(RIGHT(SUBSTITUTE(A1,"\",REPT(" ",LEN(A1))),LEN(A1)))

The upcoming Chrome "Scroll to text" feature is exactly what you are looking for....

https://github.com/bokand/ScrollToTextFragment

You basically add #targetText= at the end of the URL and the browser will scroll to the target text and highlight it after the page is loaded.

It is in the version of Chrome that is running on my desk, but currently it must be manually enabled. Presumably it will soon be enabled by default in the production Chrome builds and other browsers will follow, so OK to start adding to your links now and it will start working then.

Check whether you have declared the method where this code is executing as static. If it is static there may be some other thread resetting the ResultSet.

String.split seems to be much slower than StringTokenizer. The only advantage with split is that you get an array of the tokens. Also you can use any regular expressions in split. org.apache.commons.lang.StringUtils has a split method which works much more faster than any of two viz. StringTokenizer or String.split. But the CPU utilization for all the three is nearly the same. So we also need a method which is less CPU intensive, which I am still not able to find.

This plugin is documented rather good in https://polylang.wordpress.com/documentation.

Switching post language

The developers documentation states the following logic as a means to generate URL's for different translations of the same post

<?php while ( have_posts() ) : the_post(); ?>
<ul class='translations'><?php pll_the_languages(array('post_id' =>; $post->ID)); ?></ul>
<?php the_content(); ?>
<?php endwhile; ?>

If you want more influence on what is rendered, inspet pll_the_languages function and copy it's behaviour to your own output implementation

Switching site language

As you want buttons to switch language, this page: https://polylang.wordpress.com/documentation/frequently-asked-questions/the-language-switcher/ will give you the required info.

An implementation example:

<ul><?php pll_the_languages();?></ul>

Then style with CSS to create buttons, flags or whatever you want. It is also possible to use a widget for this, provided by te plugin

Getting current language

All plugins functions are explained here: https://polylang.wordpress.com/documentation/documentation-for-developers/functions-reference/

In this case use:

pll_current_language();

className is just a string so you can use the regular indexOf function to see if the list of classes contains another string.

For route controller method we have to define only one route. In get or post method we have to define the route separately.

And the resources method is used to creates multiple routes to handle a variety of Restful actions.

Here the Laravel documentation about this.

While you can have a default page in the MVC project, the more conventional implementation for a default view would be to use a default controller, implememented in the global.asax, through the 'RegisterRoutes(...)' method. For instance if you wanted your Public\Home controller to be your default route/view, the code would be:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Public", action = "Home", id = UrlParameter.Optional } // Parameter defaults
        );

    }

For this to be functional, you are required to have have a set Start Page in the project.

For anyone want to get time elapsed value instead of console output :

use process.hrtime() as @D.Deriso suggestion, below is my simpler approach :

function functionToBeMeasured() {
    var startTime = process.hrtime();
    // do some task...
    // ......
    var elapsedSeconds = parseHrtimeToSeconds(process.hrtime(startTime));
    console.log('It takes ' + elapsedSeconds + 'seconds');
}

function parseHrtimeToSeconds(hrtime) {
    var seconds = (hrtime[0] + (hrtime[1] / 1e9)).toFixed(3);
    return seconds;
}

You just need to change some files. This works for me.

Global.ascx

public class WebApiApplication : System.Web.HttpApplication {
    protected void Application_Start()
    {
        WebApiConfig.Register(GlobalConfiguration.Configuration);
    } }

WebApiConfig.cs

All the requests has to call this code.

public static class WebApiConfig {
    public static void Register(HttpConfiguration config)
    {
        EnableCrossSiteRequests(config);
        AddRoutes(config);
    }

    private static void AddRoutes(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "Default",
            routeTemplate: "api/{controller}/"
        );
    }

    private static void EnableCrossSiteRequests(HttpConfiguration config)
    {
        var cors = new EnableCorsAttribute(
            origins: "*", 
            headers: "*", 
            methods: "*");
        config.EnableCors(cors);
    } }

Some Controller

Nothing to change.

Web.config

You need to add handlers in your web.config

<configuration> 
  <system.webServer>
    <handlers>
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>   
  </system.webServer> 
</configuration>

KeyPress event is invoked only for character (printable) keys, KeyDown event is raised for all including nonprintable such as Control, Shift, Alt, BackSpace, etc.

UPDATE:

The keypress event is fired when a key is pressed down and that key normally produces a character value

Reference.

do it this way

         create table person(
         personid int identity(1,1) primary key,
         firstname varchar(20),
         lastname varchar(20),
         addressindex int,
         sound varchar(10)
         )

and later on create a trigger

         create trigger trigoninsert for dbo.person
         on insert 
         as
         declare @personid int;
         select @personid=personid from inserted;
         update person
         set sound=soundex(firstname) where personid=@personid;

now what i can do is i can create a procedure which looks something like this

         create procedure getfuzzi(@personid int)
          as
         declare @sound varchar(10);
         set @sound=(select sound from person where personid=@personid;
         select personid,firstname,lastname,addressindex from person
         where sound=@sound

this will return you all the names that are nearly in match with the names provided by for a particular personid

Following is the solution which worked for me. The files which I updated are as follows:

1. config.xml (Full Path: /config.xml)
2. network_security_config.xml (Full Path: /resources/android/xml/network_security_config.xml)

Changes in the corresponding files are as follows:

1. config.xml

I have added <application android:usesCleartextTraffic="true" /> tag within <edit-config> tag in the config.xml file

<platform name="android">
    <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
        <application android:usesCleartextTraffic="true" />
        <application android:networkSecurityConfig="@xml/network_security_config" />
    </edit-config>
    ...
<platform name="android">

2. network_security_config.xml

In this file I have added 2 <domain> tag within <domain-config> tag, the main domain and a sub domain as per my project requirement

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">mywebsite.in</domain>
        <domain includeSubdomains="true">api.mywebsite.in</domain>
    </domain-config>
</network-security-config>

Thanks @Ashutosh for the providing the help.

Hope it helps.

I recently needed to spawn processes for unit testing. This post was useful as I created a simple class to do that with either code as a string or code from my project. To build this class, you'll need the ICSharpCode.Decompiler and Microsoft.CodeAnalysis NuGet packages. Here's the class:

using ICSharpCode.Decompiler;
using ICSharpCode.Decompiler.CSharp;
using ICSharpCode.Decompiler.TypeSystem;
using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;

public static class CSharpRunner
{
   public static object Run(string snippet, IEnumerable<Assembly> references, string typeName, string methodName, params object[] args) =>
      Invoke(Compile(Parse(snippet), references), typeName, methodName, args);

   public static object Run(MethodInfo methodInfo, params object[] args)
   {
      var refs = methodInfo.DeclaringType.Assembly.GetReferencedAssemblies().Select(n => Assembly.Load(n));
      return Invoke(Compile(Decompile(methodInfo), refs), methodInfo.DeclaringType.FullName, methodInfo.Name, args);
   }

   private static Assembly Compile(SyntaxTree syntaxTree, IEnumerable<Assembly> references = null)
   {
      if (references is null) references = new[] { typeof(object).Assembly, typeof(Enumerable).Assembly };
      var mrefs = references.Select(a => MetadataReference.CreateFromFile(a.Location));
      var compilation = CSharpCompilation.Create(Path.GetRandomFileName(), new[] { syntaxTree }, mrefs, new CSharpCompilationOptions(OutputKind.DynamicallyLinkedLibrary));

      using (var ms = new MemoryStream())
      {
         var result = compilation.Emit(ms);
         if (result.Success)
         {
            ms.Seek(0, SeekOrigin.Begin);
            return Assembly.Load(ms.ToArray());
         }
         else
         {
            throw new InvalidOperationException(string.Join("\n", result.Diagnostics.Where(diagnostic => diagnostic.IsWarningAsError || diagnostic.Severity == DiagnosticSeverity.Error).Select(d => $"{d.Id}: {d.GetMessage()}")));
         }
      }
   }

   private static SyntaxTree Decompile(MethodInfo methodInfo)
   {
      var decompiler = new CSharpDecompiler(methodInfo.DeclaringType.Assembly.Location, new DecompilerSettings());
      var typeInfo = decompiler.TypeSystem.MainModule.Compilation.FindType(methodInfo.DeclaringType).GetDefinition();
      return Parse(decompiler.DecompileTypeAsString(typeInfo.FullTypeName));
   }

   private static object Invoke(Assembly assembly, string typeName, string methodName, object[] args)
   {
      var type = assembly.GetType(typeName);
      var obj = Activator.CreateInstance(type);
      return type.InvokeMember(methodName, BindingFlags.Default | BindingFlags.InvokeMethod, null, obj, args);
   }

   private static SyntaxTree Parse(string snippet) => CSharpSyntaxTree.ParseText(snippet);
}

To use it, call the Run methods as below:

void Demo1()
{
   const string code = @"
   public class Runner
   {
      public void Run() { System.IO.File.AppendAllText(@""C:\Temp\NUnitTest.txt"", System.DateTime.Now.ToString(""o"") + ""\n""); }
   }";

   CSharpRunner.Run(code, null, "Runner", "Run");
}

void Demo2()
{
   CSharpRunner.Run(typeof(Runner).GetMethod("Run"));
}

public class Runner
{
   public void Run() { System.IO.File.AppendAllText(@"C:\Temp\NUnitTest.txt", System.DateTime.Now.ToString("o") + "\n"); }
}

If you want not to strip, but to actually convert latin accented to non-accented characters, take a look at this question: How do I translate 8bit characters into 7bit characters? (i.e. Ü to U)

For Swift 4.0, it's now changed as:

tabBarItem.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.gray], for: .normal)
tabBarItem.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.blue], for: .selected)

You don't have to subclass the UITabBarItem if your requirement is only to change the text color. Just put the above code inside your view controller's viewDidLoad function.

For global settings change tabBarItem to UITabBarItem.appearance().

For jquery < 1.8 you can use :

$('#selectedId option').slice(index1,index2).remove()

to remove a especific range of the select options.

As of Spring 4.2.x, you can create custom mapping annotations, using @RequestMapping as a meta-annotation. So:

Is there a way to produce a "composite/inherited/aggregated" annotation with default values for consumes and produces, such that I could instead write something like:

@JSONRequestMapping(value = "/foo", method = RequestMethod.POST)

Yes, there is such a way. You can create a meta annotation like following:

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping(consumes = "application/json", produces = "application/json")
public @interface JsonRequestMapping {
    @AliasFor(annotation = RequestMapping.class, attribute = "value")
    String[] value() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "method")
    RequestMethod[] method() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "params")
    String[] params() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "headers")
    String[] headers() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "consumes")
    String[] consumes() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "produces")
    String[] produces() default {};
}

Then you can use the default settings or even override them as you want:

@JsonRequestMapping(method = POST)
public String defaultSettings() {
    return "Default settings";
}

@JsonRequestMapping(value = "/override", method = PUT, produces = "text/plain")
public String overrideSome(@RequestBody String json) {
    return json;
}

You can read more about AliasFor in spring's javadoc and github wiki.

If you have installed ruby separately and installed ruby using rbenv/rvm you budler might point to different versions.

try

gem env home

and

ruby -v

both should point to same version.check you have installed ruby using rbenv/rvm, If so delete the ruby version you installed separately.

In order for gem to work, you must invoke rbenv,

rbenv shell <ruby version> 

and

rbenv global <ruby version>

I am not sure how RVM works. Let me know if this works.

[[ -f $FILE ]] || printf '%s does not exist!\n' "$FILE"

Also, it's possible that the file is a broken symbolic link, or a non-regular file, like e.g. a socket, device or fifo. For example, to add a check for broken symlinks:

if [[ ! -f $FILE ]]; then
    if [[ -L $FILE ]]; then
        printf '%s is a broken symlink!\n' "$FILE"
    else
        printf '%s does not exist!\n' "$FILE"
    fi

Modern version

POSIX 2008 added the + marker to find which means it now automatically groups as many files as are reasonable into a single command execution, very much like xargs does, but with a number of advantages:

1. You don't have to worry about odd characters in the file names.
2. You don't have to worry about the command being invoked with zero file names.

The file name issue is a problem with xargs without the -0 option, and the 'run even with zero file names' issue is a problem with or without the -0 option — but GNU xargs has the -r or --no-run-if-empty option to prevent that happening. Also, this notation cuts down on the number of processes, not that you're likely to measure the difference in performance. Hence, you could sensibly write:

find . -exec grep something {} +

Classic version

find . -print | xargs grep something

If you're on Linux or have the GNU find and xargs commands, then use -print0 with find and -0 with xargs to handle file names containing spaces and other odd-ball characters.

find . -print0 | xargs -0 grep something

Tweaking the results from grep

If you don't want the file names (just the text) then add an appropriate option to grep (usually -h to suppressing 'headings'). To absolutely guarantee the file name is printed by grep (even if only one file is found, or the last invocation of grep is only given 1 file name), then add /dev/null to the xargs command line, so that there will always be at least two file names.
