Programs & Examples On #Datetime conversion

int day = 5;
long dayInMilliseconds = day * org.apache.commons.lang.time.DateUtils.MILLIS_PER_DAY

This answer is quite similar to the accepted answer, but doesn't override the Date prototype, and only uses one function call to check if Daylight Savings Time is in effect, rather than two.

The idea is that, since no country observes DST that lasts for 7 months^[1], in an area that observes DST the offset from UTC time in January will be different to the one in July.

While Daylight Savings Time moves clocks forwards, JavaScript always returns a greater value during Standard Time. Therefore, getting the minimum offset between January and July will get the timezone offset during DST.

We then check if the dates timezone is equal to that minimum value. If it is, then we are in DST; otherwise we are not.

The following function uses this algorithm. It takes a date object, d, and returns true if daylight savings time is in effect for that date, and false if it is not:

function isDST(d) {
    let jan = new Date(d.getFullYear(), 0, 1).getTimezoneOffset();
    let jul = new Date(d.getFullYear(), 6, 1).getTimezoneOffset();
    return Math.max(jan, jul) != d.getTimezoneOffset(); 
}

The accepted answer did not work for me. The Date returned is always the local Date and not the Date for the original Time Zone. I live in UTC+2.

//This did not work for me
Date.from(java.time.ZonedDateTime.now().toInstant()); 

I have come up with two alternative ways to get the correct Date from a ZonedDateTime.

Say you have this ZonedDateTime for Hawaii

LocalDateTime ldt = LocalDateTime.now();
ZonedDateTime zdt = ldt.atZone(ZoneId.of("US/Hawaii"); // UTC-10

or for UTC as asked originally

Instant zulu = Instant.now(); // GMT, UTC+0
ZonedDateTime zdt = zulu.atZone(ZoneId.of("UTC"));

Alternative 1

We can use java.sql.Timestamp. It is simple but it will probably also make a dent in your programming integrity

Date date1 = Timestamp.valueOf(zdt.toLocalDateTime());

Alternative 2

We create the Date from millis (answered here earlier). Note that local ZoneOffset is a must.

ZoneOffset localOffset = ZoneOffset.systemDefault().getRules().getOffset(LocalDateTime.now());
long zonedMillis = 1000L * zdt.toLocalDateTime().toEpochSecond(localOffset) + zdt.toLocalDateTime().getNano() / 1000000L;
Date date2 = new Date(zonedMillis);

For Compare two date like MM/DD/YYYY to MM/DD/YYYY . Remember First thing column type of Field must be dateTime. Example : columnName : payment_date dataType : DateTime .

after that you can easily compare it. Query is :

select  *  from demo_date where date >= '3/1/2015' and date <=  '3/31/2015'.

It very simple ...... It tested it.....

The List<> class does guarantee ordering - things will be retained in the list in the order you add them, including duplicates, unless you explicitly sort the list.

According to MSDN:

...List "Represents a strongly typed list of objects that can be accessed by index."

The index values must remain reliable for this to be accurate. Therefore the order is guaranteed.

You might be getting odd results from your code if you're moving the item later in the list, as your Remove() will move all of the other items down one place before the call to Insert().

Can you boil your code down to something small enough to post?

This is concise enough, I guess:

scala> import java.io._
import java.io._

scala> val w = new BufferedWriter(new FileWriter("output.txt"))
w: java.io.BufferedWriter = java.io.BufferedWriter@44ba4f

scala> w.write("Alice\r\nBob\r\nCharlie\r\n")

scala> w.close()

Well if I understood correctly your question. The Solution for setting the value for a given dropdownlist will be:

dropdownlist1.Text="Your Value";

This will work only if the value is existing in the data-source of the dropdownlist.

Usually I use Lodash JavaScript utility library with a pre-built groupBy() method. It is pretty easy to use, see more details here.

OnRequestPermissionResult-free and shouldShowRequestPermissionRationale-free method:

public static void requestDangerousPermission(AppCompatActivity activity, String permission) {
        if (hasPermission(activity, permission)) return;
        requestPermission();

        new Handler().postDelayed(() -> {
            if (activity.getLifecycle().getCurrentState() == Lifecycle.State.RESUMED) {
                Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                intent.setData(Uri.parse("package:" + context.getPackageName()));
                context.startActivity(intent);
            }
        }, 250);
    }

Opens device settings after 250ms if no permission popup happened (which is the case if 'Never ask again' was selected.

According to Google Maps' own help:

In your menu folder make a .menu xml file and add this xml

<item
    android:id="@+id/action_search"
    android:icon="@android:drawable/ic_menu_search"
    android:title="@string/action_search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="always|collapseActionView" />

In your fragment class overide this method and

implement SearchView.OnQueryTextListener    in your fragment class



@Override
 public void onViewCreated(View view, Bundle savedInstanceState) {    
  super.onViewCreated(view, savedInstanceState);
  setHasOptionsMenu(true);

}

Now just setup your menu xml file in fragment class

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_main, menu);

    final MenuItem item = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView)    
    MenuItemCompat.getActionView(item);


    MenuItemCompat.setOnActionExpandListener(item,
            new MenuItemCompat.OnActionExpandListener() {
                @Override
                public boolean onMenuItemActionCollapse(MenuItem item) {
                    // Do something when collapsed

                    return true; // Return true to collapse action view
                }

                @Override
                public boolean onMenuItemActionExpand(MenuItem item) {
                    // Do something when expanded
                    return true; // Return true to expand action view
                }
            });

}

You can either go the LoadLibrary/GetProcAddress route (as Harper mentioned in his answer, here's link to the run-time dynamic linking MSDN sample again) or you can link your console application to the .lib produced from the DLL project and include the hea.h file with the declaration of your function (as described in the load-time dynamic linking MSDN sample)

In both cases, you need to make sure your DLL exports the function you want to call properly. The easiest way to do it is by using __declspec(dllexport) on the function declaration (as shown in the creating a simple dynamic-link library MSDN sample), though you can do it also through the corresponding .def file in your DLL project.

For more information on the topic of DLLs, you should browse through the MSDN About Dynamic-Link Libraries topic.

this worked best for me:

        Cells(partcount + 5, "N").Value = Date + Time
        Cells(partcount + 5, "N").NumberFormat = "mm/dd/yy hh:mm:ss AM/PM"

import com.google.common.collect.Streams;

and use Streams.stream(iterator) :

Streams.stream(iterator)
       .map(v-> function(v))
       .collect(Collectors.toList());

That sounds pretty bad and weird. But reinstalling isn't that hard - download, unzip, change the default memory allocation, run Eclipse, install necessary plugins and features.

And almost all of the important preferences are in your workspace. The only important one I can think of outside of the workspace is the aforementioned memory allocation, which you can set on the command line or in the ECLIPSE.INI file.

Define a style in UserControl.Resources or Window.Resources

 <Window.Resources>
        <Style x:Key="MyButton" TargetType="Button">
            <Setter Property="OverridesDefaultStyle" Value="True" />
            <Setter Property="Cursor" Value="Hand" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Border Name="border" BorderThickness="0" BorderBrush="Black" Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Opacity" Value="0.8" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>

Then add the style to your button this way Style="{StaticResource MyButton}"

<Button Name="btnSecond" Width="350" Height="120" Margin="15" Style="{StaticResource MyButton}">
    <Button.Background>
        <ImageBrush ImageSource="/Remove_Default_Button_Effect;component/Images/WithStyle.jpg"></ImageBrush>
    </Button.Background>
</Button>

Here is the solution which worked for me.

OUTPUT: State of Cart Widget is updated, upon addition of items.

Create a globalKey for the widget you want to update by calling the trigger from anywhere

final GlobalKey<CartWidgetState> cartKey = GlobalKey();

Make sure it's saved in a file have global access such that, it can be accessed from anywhere. I save it in globalClass where is save commonly used variables through the app's state.

class CartWidget extends StatefulWidget {

  CartWidget({Key key}) : super(key: key);
  @override
  CartWidgetState createState() => CartWidgetState();
}

class CartWidgetState extends State<CartWidget> {
  @override
  Widget build(BuildContext context) {
    //return your widget
    return Container();
  }
}

Call your widget from some other class.

class HomeScreen extends StatefulWidget {

  HomeScreen ({Key key}) : super(key: key);
  @override
  HomeScreenState createState() => HomeScreen State();
}

class HomeScreen State extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return ListView(
              children:[
                 ChildScreen(), 
                 CartWidget(key:cartKey)
              ]
            );
  }
}



class ChildScreen extends StatefulWidget {

  ChildScreen ({Key key}) : super(key: key);
  @override
  ChildScreenState createState() => ChildScreen State();
}

class ChildScreen State extends State<ChildScreen> {
  @override
  Widget build(BuildContext context) {
    return InkWell(
              onTap: (){
                // This will update the state of your inherited widget/ class
                if (cartKey.currentState != null)
                    cartKey.currentState.setState(() {});
              },
              child: Text("Update The State of external Widget"),
           );
  }
}

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

In Powershell 5 escaping double quotes can be done by backtick (`). But sometimes you need to provide your double quotes escaped which can be done by backslash + backtick (\`). Eg in this curl call:

Moment.js now supports TypeScript in v2.14.1.

See: https://github.com/moment/moment/pull/3280

Directly

Might not be the best answer, but this is the brute force way, and it works for me.

1. Just download the actual moment.js file and include it in your project.
2. For example, my project looks like this:

$ tree . +-- main.js +-- main.js.map +-- main.ts +-- moment.js

3. And here's a sample source code:

```

import * as moment from 'moment';

class HelloWorld {
    public hello(input:string):string {
        if (input === '') {
            return "Hello, World!";
        }
        else {
            return "Hello, " + input + "!";
        }
    }
}

let h = new HelloWorld();
console.log(moment().format('YYYY-MM-DD HH:mm:ss'));

4. Just use node to run main.js.

Check out this snippet:

Private Sub openDialog()
    Dim fd As Office.FileDialog

    Set fd = Application.FileDialog(msoFileDialogFilePicker)

   With fd

      .AllowMultiSelect = False

      ' Set the title of the dialog box.
      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear
      .Filters.Add "Excel 2003", "*.xls"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the
      ' user picked at least one file. If the .Show method returns
      ' False, the user clicked Cancel.
      If .Show = True Then
        txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox

      End If
   End With
End Sub

I think this is what you are asking for.

If using on Windows

Process process = new Process();
process.StartInfo.Filename = "Test.txt";
process.Start();

Works for .Net Framework but for Net core 3.1 also need to set UseShellExecute to true

Process process = new Process();
process.StartInfo.Filename = "Test.txt";
process.StartInfo.UseShellExecute = true;
process.Start();

Very often you have no option to setup the sending server so what I did I changed the XMLHttpRequest.open call in my javascript to a local get-file.php file where I have the following code in it:

<?php_x000D_
  $file = file($_GET['url']);_x000D_
  echo implode('', $file);_x000D_
?>

javascript is doing this:

var xhttp = new XMLHttpRequest();_x000D_
xhttp.onreadystatechange = function() {_x000D_
  if (this.readyState == 4 && this.status == 200) {_x000D_
    // File content is now in the this.responseText_x000D_
  }_x000D_
};_x000D_
xhttp.open("GET", "get-file.php?url=http://site/file", true);_x000D_
xhttp.send();

In my case this solved the restriction/situation just perfectly. No need to hack Firefox or servers. Just load your javascript/html file with that small php file into the server and you're done.

I encountered issues where Safari wasn't firing "onchange" events on a text input field. I used a jQuery 1.7.2 "change" event and it didn't work either. I ended up using ZURB's textchange event. It works with mouseevents and can fire without leaving the field:
http://www.zurb.com/playground/jquery-text-change-custom-event

$('.inputClassToBind').bind('textchange', function (event, previousText) {
    alert($(this).attr('id'));
});

Spaces in a folder name in your header search path can cause this problem. Make sure the folders in your project do not have spaces in their names.

Like @Vonc said, there is no possibility to add a command like as of now. The only workaround is to mention the folder, to create it and add contents to it.

# add contents to folder
ADD src $HOME/src

Would create a folder called src in your directory and add contents of your folder src into this.

i had regeneratorRuntime is not defined error when i used 'async' and 'await' in my react app 'async' and 'await' is a new keywords in ES7 for that you should use babel-preset-es2017 install this devDependencies:

`

"babel-preset-es2017": "^6.24.1",
"babel-preset-react": "^6.24.1",
"babel-preset-stage-0": "^6.24.1", `

and use this

"presets": [ "es2017" , "stage-0" , "react" ]

This worked for me in every case:

ng test --include='**/dealer.service.spec.ts'

However, I usually got "TypeError: Cannot read property 'ngModule' of null" for this:

ng test --main src/app/services/dealer.service.spec.ts

Version of @angular/cli 10.0.4

This is an angular provider that I wrote, which makes use of @profitehlolz 's answer but employs memoization so that commonly used pad length-pad character combinations will not invoke the array build join needlessly:

angular.module('stringUtilities', [])
    .service('stringFunctions', [function() {
        this.padMemo={ };
        this.padLeft=function(inputString,padSize,padCharacter) {

            var memoKey=padSize+""+padCharacter;

            if(!this.padMemo[memoKey]) {

                this.padMemo[memoKey]= new Array(1 + padSize).join(padCharacter);
            }

           var pad=this.padMemo[memoKey];
           return (pad + inputString).slice(-pad.length);
       };
}]);

EDIT: As noted in comments, these days I'm happy to use Interlocked for the cases of a single variable where it's obviously okay. When it gets more complicated, I'll still revert to locking...

Using volatile won't help when you need to increment - because the read and the write are separate instructions. Another thread could change the value after you've read but before you write back.

Personally I almost always just lock - it's easier to get right in a way which is obviously right than either volatility or Interlocked.Increment. As far as I'm concerned, lock-free multi-threading is for real threading experts, of which I'm not one. If Joe Duffy and his team build nice libraries which will parallelise things without as much locking as something I'd build, that's fabulous, and I'll use it in a heartbeat - but when I'm doing the threading myself, I try to keep it simple.

INSERT INTO Destination SELECT * FROM Source;

Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.

Simple code example for observing display:none switching:

// Start observing visbility of element. On change, the
//   the callback is called with Boolean visibility as
//   argument:

function respondToVisibility(element, callback) {
  var options = {
    root: document.documentElement,
  };

  var observer = new IntersectionObserver((entries, observer) => {
    entries.forEach(entry => {
      callback(entry.intersectionRatio > 0);
    });
  }, options);

  observer.observe(element);
}

I have tried to do it this way, but it is very flickery

I think your problem is your version numbers. Try making 8.1 --> 8.01, and so forth. That should put the points in the right order.

Alternatively, you could plot using X, where X is the column number you want, instead of using 1:X. That will plot those values on the y axis and integers on the x axis. Try:

plot "ls.dat" using 2 title 'Removed' with lines, \
     "ls.dat" using 3 title 'Added' with lines, \
     "ls.dat" using 4 title 'Modified' with lines

Cheap trick:

Convert.ToString((object)stringVar) == “”

This works because Convert.ToString(object) returns an empty string if object is null. Convert.ToString(string) returns null if string is null.

(Or, if you're using .NET 2.0 you could always using String.IsNullOrEmpty.)

If you're using Bash you could also use one of the following commands:

printf '%(%Y%m%d%H%M%S)T'       # prints the current time
printf '%(%Y%m%d%H%M%S)T' -1    # same as above
printf '%(%Y%m%d%H%M%S)T' -2    # prints the time the shell was invoked

You can use the Option -v varname to store the result in $varname instead of printing it to stdout:

printf -v varname '%(%Y%m%d%H%M%S)T'

While the date command will always be executed in a subshell (i.e. in a separate process) printf is a builtin command and will therefore be faster.

This has been mentioned, but somehow nobody managed to actually get it right.

On O(n) solution would be:

indices = {0, 2}
somelist = [i for j, i in enumerate(somelist) if j not in indices]

This is really close to SilentGhost's version, but adds two braces.

Combination of @[macbirdie] and @[Adrian Borchardt] answer. Which proves to be very useful in production environment (not messing up previously existing warning, especially during cross-platform compile)

#if (_MSC_VER >= 1400)         // Check MSC version
#pragma warning(push)
#pragma warning(disable: 4996) // Disable deprecation
#endif 
//...                          // ...
strcat(base, cat);             // Sample depreciated code
//...                          // ...
#if (_MSC_VER >= 1400)         // Check MSC version
#pragma warning(pop)           // Renable previous depreciations
#endif

it worked for me after deleting and adding the server back.

The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.

When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.

Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:

http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database

Update Collation of all fields in database on the fly

http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx

If you need to have different collation on two objects or can't change collations - you can still JOIN between them using COLLATE command, and choosing the collation you want for join.

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS 

or using default database collation:

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT

If you don't have access to the classes to change the properties, or don't want to always use the same rename property, renaming can also be done by creating a custom resolver.

For example, if you have a class called MyCustomObject, that has a property called LongPropertyName, you can use a custom resolver like this…

public class CustomDataContractResolver : DefaultContractResolver
{
  public static readonly CustomDataContractResolver Instance = new CustomDataContractResolver ();

  protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
  {
    var property = base.CreateProperty(member, memberSerialization);
    if (property.DeclaringType == typeof(MyCustomObject))
    {
      if (property.PropertyName.Equals("LongPropertyName", StringComparison.OrdinalIgnoreCase))
      {
        property.PropertyName = "Short";
      }
    }
    return property;
  }
}

Then call for serialization and supply the resolver:

 var result = JsonConvert.SerializeObject(myCustomObjectInstance,
                new JsonSerializerSettings { ContractResolver = CustomDataContractResolver.Instance });

And the result will be shortened to {"Short":"prop value"} instead of {"LongPropertyName":"prop value"}

Dan Abramov wrote an article on this topic:

And the gist of it is that it's helpful to have a habit of passing it to avoid this scenario, that honestly, I don't see it unlikely to happen:

class Component {
  constructor(props) {
    this.props = props;
    // ...
  }
}

// Inside your code
class Button extends React.Component {
  constructor(props) {
    super(); //  We forgot to pass props
    console.log(props);      // ? {}
    console.log(this.props); //  undefined 
  }
  // ...
}

A possible solution:

import pandas as pd
import numpy as np

df=pd.DataFrame(['ONE','Two', np.nan],columns=['x']) 
xLower = df["x"].map(lambda x: x if type(x)!=str else x.lower())
print (xLower)

And a result:

0    one
1    two
2    NaN
Name: x, dtype: object

Not sure about the efficiency though.

Either fully avoid null in DB via NOT NULL and in Hibernate entity via @Column(nullable = false) accordingly or use Long wrapper instead of you long primitives.

A primitive is not an Object, therefore u can't assign null to it.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

ax[0, 0].plot(range(10), 'r') #row=0, col=0
ax[1, 0].plot(range(10), 'b') #row=1, col=0
ax[0, 1].plot(range(10), 'g') #row=0, col=1
ax[1, 1].plot(range(10), 'k') #row=1, col=1
plt.show()

A clean and functional solution

const combineFilters = (...filters) => (item) => {
    return filters.map((filter) => filter(item)).every((x) => x === true);
};

then you use it like so:

const filteredArray = arr.filter(combineFilters(filterFunc1, filterFunc2));

and filterFunc1 for example might look like this:

const filterFunc1 = (item) => {
  return item === 1 ? true : false;
};

For folks who find this posting through the search engines, another possible cause of this problem is from importing the wrong package version of @Transient. Make sure that you import javax.persistence.transient and not some other package.

As this Spring's Jira ticket, it is an intentional design. But the following code works for me.

public static Map<String, Object> getAllKnownProperties(Environment env) {
    Map<String, Object> rtn = new HashMap<>();
    if (env instanceof ConfigurableEnvironment) {
        for (PropertySource<?> propertySource : ((ConfigurableEnvironment) env).getPropertySources()) {
            if (propertySource instanceof EnumerablePropertySource) {
                for (String key : ((EnumerablePropertySource) propertySource).getPropertyNames()) {
                    rtn.put(key, propertySource.getProperty(key));
                }
            }
        }
    }
    return rtn;
}

I'm not 100% sure on this, but I think that adding a view to the view hierarchy directly means calling -addSubview: on the view controller's view (e.g., [viewController.view addSubview:anotherViewController.view]) instead of pushing a new view controller onto the navigation controller's stack.

Automated Tasks: Cron

Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically. You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.

Configuring Cron Tasks

In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:

*/10 * * * * /usr/bin/php /opt/test.php

In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.

* is a wildcard, meaning "every time".

Start with finding out your PHP binary by typing in command line:

whereis php

The output should be something like:

php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz

Specify correctly the full path in your command.

Type the following command to enter cronjob:

crontab -e

To see what you got in crontab.

EDIT 1:

To exit from vim editor without saving just click:

Shift+:

And then type q!

You can redirect stdout to nul to hide it.

COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >nul

Just add >nul to the commands you want to hide the output from.

Here you can see all the different ways of redirecting the std streams.

if you have an object you can define it as @property so you can get results without a call, e.g.

class Item:
    @property
    def results(self):
        return something

then in the template:

<% for result in item.results %>
...
<% endfor %>

If multiple types are possible, the method itself does not know the type to cast, but the caller does, you might use something like this:

void TheObliviousHelperMethod<T>(object obj) {
    (T)obj.ThatClassMethodYouWantedToInvoke();
}

// Meanwhile, where the method is called:
TheObliviousHelperMethod<ActualType>(obj);

Restrictions on the type could be added using the where keyword after the parentheses.

I usually send the text I want to copy as an sms message through telnet and then copy the text from the sms message. Here's how:

Connect through telnet:

• Syntax: telnet localhost <port>
• Example: telnet localhost 5554

(5554 is the default port. The title bar of the emulator shows the port that is being used, so you can see if it's different).

Send message:

• Syntax: sms send <senders phone number> <message>
• Example: sms send 1231231234 This is the message you want to send

(You can just make up the senders phone number)

This works really well for links as the message is automatically converted into a hyperlink which you can click without having to copy / paste it into the browser.

Once the emulator receives the message you can copy it and paste it wherever you like.

Just to clarify why :set list won't show CR's as ^M without e ++ff=unix and why :set list has nothing to do with ^M's.

Internally when Vim reads a file into its buffer, it replaces all line-ending characters with its own representation (let's call it $'s). To determine what characters should be removed, it firstly detects in what format line endings are stored in a file. If there are only CRLF '\r\n' or only CR '\r' or only LF '\n' line-ending characters, then the 'fileformat' is set to dos, mac and unix respectively.

When list option is set, Vim displays $ character when the line break occurred no matter what fileformat option has been detected. It uses its own internal representation of line-breaks and that's what it displays.

Now when you write buffer to the disc, Vim inserts line-ending characters according to what fileformat options has been detected, essentially converting all those internal $'s with appropriate characters. If the fileformat happened to be unix then it will simply write \n in place of its internal line-break.

The trick is to force Vim to read a dos encoded file as unix one. The net effect is that it will remove all \n's leaving \r's untouched and display them as ^M's in your buffer. Setting :set list will additionally show internal line-endings as $. After all, you see ^M$ in place of dos encoded line-breaks.

Also notice that :set list has nothing to do with showing ^M's. You can check it by yourself (make sure you have disabled list option first) by inserting single CR using CTRL-V followed by Enter in insert mode. After writing buffer to disc and opening it again you will see ^M despite list option being set to 0.

You can find more about file formats on http://vim.wikia.com/wiki/File_format or by typing:help 'fileformat' in Vim.

Alternatively YUI has http://yuilibrary.com/yui/docs/api/classes/QueryString.html#method_stringify.

For example:

var data = { one: 'first', two: 'second' };
var result = Y.QueryString.stringify(data);

After a fight with this issue, I finally end up with this workaround:

/**
 * Dismiss {@link ProgressDialog} with check for nullability and SDK version
 *
 * @param dialog instance of {@link ProgressDialog} to dismiss
 */
public void dismissProgressDialog(ProgressDialog dialog) {
    if (dialog != null && dialog.isShowing()) {

            //get the Context object that was used to great the dialog
            Context context = ((ContextWrapper) dialog.getContext()).getBaseContext();

            // if the Context used here was an activity AND it hasn't been finished or destroyed
            // then dismiss it
            if (context instanceof Activity) {

                // Api >=17
                if (!((Activity) context).isFinishing() {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                        if (!((Activity) context).isDestroyed()) {
                            dismissWithExceptionHandling(dialog);
                        }
                    } else { 
                        // Api < 17. Unfortunately cannot check for isDestroyed()
                        dismissWithExceptionHandling(dialog);
                    }
                }
            } else
                // if the Context used wasn't an Activity, then dismiss it too
                dismissWithExceptionHandling(dialog);
        }
        dialog = null;
    }
}

/**
 * Dismiss {@link ProgressDialog} with try catch
 *
 * @param dialog instance of {@link ProgressDialog} to dismiss
 */
public void dismissWithExceptionHandling(ProgressDialog dialog) {
    try {
        dialog.dismiss();
    } catch (final IllegalArgumentException e) {
        // Do nothing.
    } catch (final Exception e) {
        // Do nothing.
    } finally {
        dialog = null;
    }
}

Sometimes, good exception handling works well if there wasn't a better solution for this issue.

You shouldn't use flag e (or eval in general).

You can also use T-Regx library

pattern('(^|_)([a-z])')->replace($word)->by()->group(2)->callback('strtoupper');

First make sure the PHP files themselves are UTF-8 encoded.

The meta tag is ignored by some browser. If you only use ASCII-characters, it doesn't matter anyway.

http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

header('Content-Type: text/html; charset=utf-8');

function writeCookie(name,value,days) {
    var date, expires;
    if (days) {
        date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        expires = "; expires=" + date.toGMTString();
            }else{
        expires = "";
    }
    document.cookie = name + "=" + value + expires + "; path=/";
}

When I face this problem I just edit the file and save it... works like charm

As @Renich suggests (but with an important typo that has not been fixed unfortunately), you can also use extended globbing for pattern matching. So you can use the same patterns you use to match files in command arguments (e.g. ls *.pdf) inside of bash comparisons.

For your particular case you can do the following.

if [[ "${cms}" != @(wordpress|magento|typo3) ]]

The @ means "Matches one of the given patterns". So this is basically saying cms is not equal to 'wordpress' OR 'magento' OR 'typo3'. In normal regular expression syntax @ is similar to just ^(wordpress|magento|typo3)$.

Mitch Frazier has two good articles in the Linux Journal on this Pattern Matching In Bash and Bash Extended Globbing.

For more background on extended globbing see Pattern Matching (Bash Reference Manual).

After you clone repository repo, you can edit repo/.git/config and add some configuration like below:

[user]
    name = you_name
    password = you_password
[credential]
    helper = store

Then you won't be asked for username and password again.

Would the following Macro help you?

Sub activateSheet(sheetname As String)
'activates sheet of specific name
    Worksheets(sheetname).Activate
End Sub

Basically you want to make use of the .Activate function. Or you can use the .Select function like so:

Sub activateSheet(sheetname As String)
'selects sheet of specific name
    Sheets(sheetname).Select
End Sub

In my case the issue turned out to be the alias name I had given to the table. "oa" seems to be not acceptable for SQL Server.

FB recommends to add the async all.js include right after body, so that FB object get prepared when you use it in page.

You can also have artificial delay using setTimeout to make sure FB object is loaded. e.g.

<script>setTimeout(function(){
FB.Event.subscribe('edge.create',
function (response) {
    alert('msg via fb');
});},2000);
</script>

Usually, only the endpoint that issues an 'active close' should go into TIME_WAIT state. So, if possible, have your clients issue the active close which will leave the TIME_WAIT on the client and NOT on the server.

See here: http://www.serverframework.com/asynchronousevents/2011/01/time-wait-and-its-design-implications-for-protocols-and-scalable-servers.html and http://www.isi.edu/touch/pubs/infocomm99/infocomm99-web/ for details (the later also explains why it's not always possible due to protocol design that doesn't take TIME_WAIT into consideration).

As referenced in my answer to Applying rounded corners to paths/polygons, I have written a routine in javascript for generically rounding corners of SVG paths, with examples, here: http://plnkr.co/edit/kGnGGyoOCKil02k04snu.

It will work independently from any stroke effects you may have. To use, include the rounding.js file from the Plnkr and call the function like so:

roundPathCorners(pathString, radius, useFractionalRadius)

The result will be the rounded path.

The results look like this:

How to use a clock and do assertions

This example shows how to generate a clock, and give inputs and assert outputs for every cycle. A simple counter is tested here.

The key idea is that the process blocks run in parallel, so the clock is generated in parallel with the inputs and assertions.

library ieee;
use ieee.std_logic_1164.all;

entity counter_tb is
end counter_tb;

architecture behav of counter_tb is
    constant width : natural := 2;
    constant clk_period : time := 1 ns;

    signal clk : std_logic := '0';
    signal data : std_logic_vector(width-1 downto 0);
    signal count : std_logic_vector(width-1 downto 0);

    type io_t is record
        load : std_logic;
        data : std_logic_vector(width-1 downto 0);
        count : std_logic_vector(width-1 downto 0);
    end record;
    type ios_t is array (natural range <>) of io_t;
    constant ios : ios_t := (
        ('1', "00", "00"),
        ('0', "UU", "01"),
        ('0', "UU", "10"),
        ('0', "UU", "11"),

        ('1', "10", "10"),
        ('0', "UU", "11"),
        ('0', "UU", "00"),
        ('0', "UU", "01")
    );
begin
    counter_0: entity work.counter port map (clk, load, data, count);

    process
    begin
        for i in ios'range loop
            load <= ios(i).load;
            data <= ios(i).data;
            wait until falling_edge(clk);
            assert count = ios(i).count;
        end loop;
        wait;
    end process;

    process
    begin
        for i in 1 to 2 * ios'length loop
            wait for clk_period / 2;
            clk <= not clk;
        end loop;
        wait;
    end process;
end behav;

The counter would look like this:

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all; -- unsigned

entity counter is
    generic (
        width : in natural := 2
    );
    port (
        clk, load : in std_logic;
        data : in std_logic_vector(width-1 downto 0);
        count : out std_logic_vector(width-1 downto 0)
    );
end entity counter;

architecture rtl of counter is
    signal cnt : unsigned(width-1 downto 0);
begin
    process(clk) is
    begin
        if rising_edge(clk) then
            if load = '1' then
                cnt <= unsigned(data);
            else
                cnt <= cnt + 1;
            end if;
        end if;
    end process;
    count <= std_logic_vector(cnt);
end architecture rtl;

This is how I solved the problem

ssh -i <key> ec2-user@<ec2 ip>

1 Step - Install a required extension

sudo apt-get install libz-dev -y

2 Step - Install the PHP extension

pecl install zlib zip

3 Step - Restart your Apache

sudo /etc/init.d/apache2 restart

If does not work you can check if the zip.ini is called in your phpinfo, to check if the zip.so was included.

If you looking for something short and simple, maybe it will be enough for you:

class A(object):
    def __init__(self, l):
        self.data = l

    def __iter__(self):
        return iter(self.data)

example of usage:

In [3]: a = A([2,3,4])

In [4]: [i for i in a]
Out[4]: [2, 3, 4]

The closest thing in C# 3.0, is that you can use a constructor to initialize properties:

Stuff.Elements.Foo foo = new Stuff.Elements.Foo() {Name = "Bob Dylan", Age = 68, Location = "On Tour", IsCool = true}

combining 3 answers together: (because a select statement does not execute the DDL)

set pagesize 0

alter session set skip_unusable_indexes = true;
spool c:\temp\disable_indexes.sql
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;
spool off
@c:\temp\disable_indexes.sql

Do import...

select 'alter index ' || u.index_name || 
' rebuild online;' from user_indexes u;

Note this assumes that the import is going to happen in the same (sqlplus) session.
If you are calling "imp" it will run in a separate session so you would need to use "ALTER SYSTEM" instead of "ALTER SESSION" (and remember to put the parameter back the way you found it.

As a picture is worth a thousand words..

When you find the IIS6 manager (I have found that searching for IIS may return 2 results) go to the SMTP server properties then 'Access' then press the relay button.

Then you can either select all or only allow certain ip's like 127.0.0.1

with Apache PDFBox it goes like this:

PDDocument document = PDDocument.load(new File("test.pdf"));
if (!document.isEncrypted()) {
    PDFTextStripper stripper = new PDFTextStripper();
    String text = stripper.getText(document);
    System.out.println("Text:" + text);
}
document.close();

Here is an excellent treatment on the Mozilla Development Network (MDN) of this issue for standard JavaScript (if you do not wish to rely on jQuery or understand it better in general):

https://developer.mozilla.org/en-US/docs/DOM/element.addEventListener

Here is a discussion of event flow from a link in the above treatment:

http://www.w3.org/TR/DOM-Level-3-Events/#event-flow

Some key points are:

• It allows adding more than a single handler for an event
• It gives you finer-grained control of the phase when the listener gets activated (capturing vs. bubbling)
• It works on any DOM element, not just HTML elements
• The value of "this" passed to the event is not the global object (window), but the element from which the element is fired. This is very convenient.
• Code for legacy IE browsers is simple and included under the heading "Legacy Internet Explorer and attachEvent"
• You can include parameters if you enclose the handler in an anonymous function

I believe Double.NaN might be able to cover this. That is the only 'null' value double contains.

If Java is installed on the target machine, there is no need to create an .exe file. A .jar file should be sufficient.

I want to update the answer for exception handling in Psr-7 Guzzle, Guzzle7 and HTTPClient(expressive, minimal API around the Guzzle HTTP client provided by laravel).

Guzzle7 (same works for Guzzle 6 as well)

Using RequestException, RequestException catches any exception that can be thrown while transferring requests.

try{
  $client = new \GuzzleHttp\Client(['headers' => ['Authorization' => 'Bearer ' . $token]]);
  
  $guzzleResponse = $client->get('/foobar');
  // or can use
  // $guzzleResponse = $client->request('GET', '/foobar')
    if ($guzzleResponse->getStatusCode() == 200) {
         $response = json_decode($guzzleResponse->getBody(),true);
         //perform your action with $response 
    } 
}
catch(\GuzzleHttp\Exception\RequestException $e){
   // you can catch here 400 response errors and 500 response errors
   // You can either use logs here use Illuminate\Support\Facades\Log;
   $error['error'] = $e->getMessage();
   $error['request'] = $e->getRequest();
   if($e->hasResponse()){
       if ($e->getResponse()->getStatusCode() == '400'){
           $error['response'] = $e->getResponse(); 
       }
   }
   Log::error('Error occurred in get request.', ['error' => $error]);
}catch(Exception $e){
   //other errors 
}

Psr7 Guzzle

use GuzzleHttp\Psr7;
use GuzzleHttp\Exception\RequestException;

try {
    $client->request('GET', '/foo');
} catch (RequestException $e) {
    $error['error'] = $e->getMessage();
    $error['request'] = Psr7\Message::toString($e->getRequest());
    if ($e->hasResponse()) {
        $error['response'] = Psr7\Message::toString($e->getResponse());
    }
    Log::error('Error occurred in get request.', ['error' => $error]);
}

For HTTPClient

use Illuminate\Support\Facades\Http;
try{
    $response = Http::get('http://api.foo.com');
    if($response->successful()){
        $reply = $response->json();
    }
    if($response->failed()){
        if($response->clientError()){
            //catch all 400 exceptions
            Log::debug('client Error occurred in get request.');
            $response->throw();
        }
        if($response->serverError()){
            //catch all 500 exceptions
            Log::debug('server Error occurred in get request.');
            $response->throw();
        }
        
    }
 }catch(Exception $e){
     //catch the exception here
 }

The APK file is in the /workspace/PROJECT_FOLDER/bin directory. To install the APK file in a real device:

1. Connect your real device with a PC/laptop.

2. Go to sdk/tools/ using a terminal or command prompt.

3. adb install <FILE PATH OF .APK FILE>

That's it...

I used astyle to re-indent all my C/C++ code after finding mixed tabs and spaces. It also has options to force a particular brace style if you'd like.

Here is what backup in this sense really means:

Android's backup service allows you to copy your persistent application data to remote "cloud" storage, in order to provide a restore point for the application data and settings. If a user performs a factory reset or converts to a new Android-powered device, the system automatically restores your backup data when the application is re-installed. This way, your users don't need to reproduce their previous data or application settings.

~Taken from http://developer.android.com/guide/topics/data/backup.html

You can register for this backup service as a developer here: https://developer.android.com/google/backup/signup.html

The type of data that can be backed up are files, databases, sharedPreferences, cache, and lib. These are generally stored in your device's /data/data/[com.myapp] directory, which is read-protected and cannot be accessed unless you have root privileges.

UPDATE: You can see this flag listed on BackupManager's api doc: BackupManager

I've changed the recursion to iteration.

def MovingTheBall(listOfBalls,position,numCell):
while 1:
    stop=1
    positionTmp = (position[0]+choice([-1,0,1]),position[1]+choice([-1,0,1]),0)
    for i in range(0,len(listOfBalls)):
        if positionTmp==listOfBalls[i].pos:
            stop=0
    if stop==1:
        if (positionTmp[0]==0 or positionTmp[0]>=numCell or positionTmp[0]<=-numCell or positionTmp[1]>=numCell or positionTmp[1]<=-numCell):
            stop=0
        else:
            return positionTmp

Works good :D

If you like the pipe mode, this is the most clean solution:

tar c some-dir | xz > some-dir.tar.xz

It's not necessary to put the f option in order to deal with files and then to use - to specify that the file is the standard input. It's also not necessary to specify the -z option for xz, because it's default.

It works with gzip and bzip2 too:

tar c some-dir | gzip > some-dir.tar.gz

or

tar c some-dir | bzip2 > some-dir.tar.bz2

Decompressing is also quite straightforward:

xzcat tarball.tar.xz | tar x
bzcat tarball.tar.bz2 | tar x
zcat tarball.tar.gz | tar x

If you have only tar archive, you can use cat:

cat archive.tar | tar x

If you need to list the files only, use tar t.

Before you begin to curse your application you need to check this:

1. Is your application the only one using that instance of SQL Server. a. If the answer to that is NO then you need to investigate how the other applications are consuming resources on your SQl Server.run b. If the answer is yes then you must investigate your application.

2. Run SQL Server Profiler and check what activity is happening in other applications (1a) using SQL Server and check your application as well (1b).

3. If indeed your application is starved off of resources then you need to make farther investigations. For more read on this http://sqlserverplanet.com/troubleshooting/sql-server-slowness

bmail. Just install the EXE and run a line like this:

bmail -s myMailServer -f [email protected] -t [email protected] -a "Production Release Performed"

dmidecode -t 17 | grep  Size:

Adding all above values displayed after "Size: " will give exact total physical size of all RAM sticks in server.

16 bit installer will not work on windows 7 it's no longer supported by win 7 the most recent supported version of windows that can run 16 bit installer is vista 32-bit even vista 64-bit doesn't support 16-bit installer.... reference http://support.microsoft.com/kb/946765

Use the -O file option.

E.g.

wget google.com
...
16:07:52 (538.47 MB/s) - `index.html' saved [10728]

vs.

wget -O foo.html google.com
...
16:08:00 (1.57 MB/s) - `foo.html' saved [10728]

I'm not sure why the simplest way has been ignored/omitted in the answers above:

SELECT FORMAT(GetDate(),'yyyy-MM-dd');--= 2020-01-02

SELECT FORMAT(GetDate(),'dd MMM yyyy HH:mm:ss');-- = 02 Jan 2020 08:08:08

I prefer the second one because whichever language you speak, you will understand what date it is!

Also SQL Server always 'understands' it when you send that to your save procedure, regardless of which regional formats are set in the computers - I always use full year (yyyy), month name (MMM) and 24 hour format (capital HH) for hour in my programming.

You need to add a dataType - http://api.jquery.com/jQuery.ajax/

$(document).ready(function() {
    $("#lesen").click(function() {
        $.ajax({
            url : "helloworld.txt",
            dataType: "text",
            success : function (data) {
                $(".text").html(data);
            }
        });
    });
}); 

ini_set('max_execution_time', 0); or create file name called php.ini and enter the first line max_execution_time=0 then save it and put the file in your root folder of your application.

That's it. Good luck.

I think I know the reason for this exception. You might be running this code snippet in multiple threads.

HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.

The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.

If you just want the date:

SELECT MIN(date) as EarliestDate
FROM YourTable
WHERE id = 2

If you want all of the information:

SELECT TOP 1 id, name, score, date
FROM YourTable
WHERE id = 2
ORDER BY Date

Prevent loops when you can. Loops often lead to cursors, and cursors are almost never necessary and very often really inefficient.

Basically you have two ways to iterate over all elements:

1. Using recursion (the most common way I think):

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
        .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));
    doSomething(document.getDocumentElement());
}

public static void doSomething(Node node) {
    // do something with the current node instead of System.out
    System.out.println(node.getNodeName());

    NodeList nodeList = node.getChildNodes();
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentNode = nodeList.item(i);
        if (currentNode.getNodeType() == Node.ELEMENT_NODE) {
            //calls this method for all the children which is Element
            doSomething(currentNode);
        }
    }
}

2. Avoiding recursion using getElementsByTagName() method with * as parameter:

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
            .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));

    NodeList nodeList = document.getElementsByTagName("*");
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node node = nodeList.item(i);
        if (node.getNodeType() == Node.ELEMENT_NODE) {
            // do something with the current element
            System.out.println(node.getNodeName());
        }
    }
}

I think these ways are both efficient.
Hope this helps.

Java does not have such feature. Instead you can either create regular subclass of your list implementation or create anonymous inner class:

List<String> list = new ArrayList<String>() {
   public String getData() {
       return ""; // add your implementation here. 
   }
};

The problem is to call this method. You can do it "in place":

new ArrayList<String>() {
   public String getData() {
       return ""; // add your implementation here. 
   }
}.getData();

Please check if you are were passing method as POST instead as GET. if so you will get same error as a you posted above.

$http({               
 method: 'GET',

The request entity's media type 'text/plain' is not supported for this resource.

Edit: New article by Dave Abrahams on cpp-next:

Want speed? Pass by value.

Pass by value for structs where the copying is cheap has the additional advantage that the compiler may assume that the objects don't alias (are not the same objects). Using pass-by-reference the compiler cannot assume that always. Simple example:

foo * f;

void bar(foo g) {
    g.i = 10;
    f->i = 2;
    g.i += 5;
}

the compiler can optimize it into

g.i = 15;
f->i = 2;

since it knows that f and g doesn't share the same location. if g was a reference (foo &), the compiler couldn't have assumed that. since g.i could then be aliased by f->i and have to have a value of 7. so the compiler would have to re-fetch the new value of g.i from memory.

For more pratical rules, here is a good set of rules found in Move Constructors article (highly recommended reading).

• If the function intends to change the argument as a side effect, take it by non-const reference.
• If the function doesn't modify its argument and the argument is of primitive type, take it by value.
• Otherwise take it by const reference, except in the following cases
  • If the function would then need to make a copy of the const reference anyway, take it by value.

"Primitive" above means basically small data types that are a few bytes long and aren't polymorphic (iterators, function objects, etc...) or expensive to copy. In that paper, there is one other rule. The idea is that sometimes one wants to make a copy (in case the argument can't be modified), and sometimes one doesn't want (in case one wants to use the argument itself in the function if the argument was a temporary anyway, for example). The paper explains in detail how that can be done. In C++1x that technique can be used natively with language support. Until then, i would go with the above rules.

Examples: To make a string uppercase and return the uppercase version, one should always pass by value: One has to take a copy of it anyway (one couldn't change the const reference directly) - so better make it as transparent as possible to the caller and make that copy early so that the caller can optimize as much as possible - as detailed in that paper:

my::string uppercase(my::string s) { /* change s and return it */ }

However, if you don't need to change the parameter anyway, take it by reference to const:

bool all_uppercase(my::string const& s) { 
    /* check to see whether any character is uppercase */
}

However, if you the purpose of the parameter is to write something into the argument, then pass it by non-const reference

bool try_parse(T text, my::string &out) {
    /* try to parse, write result into out */
}

Just incase u didnt understand

e.g is that lets say i have a JSON STRING ..NOT YET A JSON OBJECT OR ARRAY.

so if in javascript u parse the string as

var body={
  "id": 1,
  "deleted_at": null,
  "open_order": {
    "id": 16,
    "status": "open"}

var jsonBody = JSON.parse(body.open_order); //HERE THE ERROR NOW APPEARS BECAUSE THE STRING IS NOT A JSON OBJECT YET!!!! 
//TODO SO
var jsonBody=JSON.parse(body)//PASS THE BODY FIRST THEN LATER USE THE jsonBody to get the open_order

var OpenOrder=jsonBody.open_order;

Great answers above

Starting from material-components-android 1.2.0-alpha01, you can use new slider component

ex:

Modify thumbSize, thumbColor, trackColor accordingly.

<com.google.android.material.slider.Slider
        android:id="@+id/slider"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:valueFrom="20f"
        android:valueTo="70f"
        android:stepSize="10"
        app:thumbRadius="20dp"
        app:thumbColor="@color/colorAccent"
        app:trackColor="@android:color/darker_gray"
        />

Note: Track corners are not round.

You can't effectively use Distinct on a collection of objects (without additional work). I will explain why.

The documentation says:

It uses the default equality comparer, Default, to compare values.

For objects that means it uses the default equation method to compare objects (source). That is on their hash code. And since your objects don't implement the GetHashCode() and Equals methods, it will check on the reference of the object, which are not distinct.

ButterKnife is probably the best solution for the clutter problem. It uses annotation processors to generate the so called "old method" boilerplate code.

But the onClick method can still be used, with a custom inflator.

How to use

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup cnt, Bundle state) {
    inflater = FragmentInflatorFactory.inflatorFor(inflater, this);
    return inflater.inflate(R.layout.fragment_main, cnt, false);
}

Implementation

public class FragmentInflatorFactory implements LayoutInflater.Factory {

    private static final int[] sWantedAttrs = { android.R.attr.onClick };

    private static final Method sOnCreateViewMethod;
    static {
        // We could duplicate its functionallity.. or just ignore its a protected method.
        try {
            Method method = LayoutInflater.class.getDeclaredMethod(
                    "onCreateView", String.class, AttributeSet.class);
            method.setAccessible(true);
            sOnCreateViewMethod = method;
        } catch (NoSuchMethodException e) {
            // Public API: Should not happen.
            throw new RuntimeException(e);
        }
    }

    private final LayoutInflater mInflator;
    private final Object mFragment;

    public FragmentInflatorFactory(LayoutInflater delegate, Object fragment) {
        if (delegate == null || fragment == null) {
            throw new NullPointerException();
        }
        mInflator = delegate;
        mFragment = fragment;
    }

    public static LayoutInflater inflatorFor(LayoutInflater original, Object fragment) {
        LayoutInflater inflator = original.cloneInContext(original.getContext());
        FragmentInflatorFactory factory = new FragmentInflatorFactory(inflator, fragment);
        inflator.setFactory(factory);
        return inflator;
    }

    @Override
    public View onCreateView(String name, Context context, AttributeSet attrs) {
        if ("fragment".equals(name)) {
            // Let the Activity ("private factory") handle it
            return null;
        }

        View view = null;

        if (name.indexOf('.') == -1) {
            try {
                view = (View) sOnCreateViewMethod.invoke(mInflator, name, attrs);
            } catch (IllegalAccessException e) {
                throw new AssertionError(e);
            } catch (InvocationTargetException e) {
                if (e.getCause() instanceof ClassNotFoundException) {
                    return null;
                }
                throw new RuntimeException(e);
            }
        } else {
            try {
                view = mInflator.createView(name, null, attrs);
            } catch (ClassNotFoundException e) {
                return null;
            }
        }

        TypedArray a = context.obtainStyledAttributes(attrs, sWantedAttrs);
        String methodName = a.getString(0);
        a.recycle();

        if (methodName != null) {
            view.setOnClickListener(new FragmentClickListener(mFragment, methodName));
        }
        return view;
    }

    private static class FragmentClickListener implements OnClickListener {

        private final Object mFragment;
        private final String mMethodName;
        private Method mMethod;

        public FragmentClickListener(Object fragment, String methodName) {
            mFragment = fragment;
            mMethodName = methodName;
        }

        @Override
        public void onClick(View v) {
            if (mMethod == null) {
                Class<?> clazz = mFragment.getClass();
                try {
                    mMethod = clazz.getMethod(mMethodName, View.class);
                } catch (NoSuchMethodException e) {
                    throw new IllegalStateException(
                            "Cannot find public method " + mMethodName + "(View) on "
                                    + clazz + " for onClick");
                }
            }

            try {
                mMethod.invoke(mFragment, v);
            } catch (InvocationTargetException e) {
                throw new RuntimeException(e);
            } catch (IllegalAccessException e) {
                throw new AssertionError(e);
            }
        }

}

Whenever you have a module followed by a variable on the same line in ansible the parser will treat the reference variable as the beginning of an in-line dictionary. For example:

- name: some example
  command: {{ myapp }} -a foo

The default here is to parse the first part of {{ myapp }} -a foo as a dictionary instead of a string and you will get an error.

So you must quote the argument like so:

- name: some example
  command: "{{ myapp }} -a foo"

I use it when, in a function that accepts a reference to an object of the same type, I want to make it perfectly clear which object I'm referring to, where.

For example

class AABB
{
  // ... members
  bool intersects( AABB other )
  {
    return other.left() < this->right() &&
           this->left() < other.right() &&

           // +y increases going down
           other.top() < this->bottom() &&
           this->top() < other.bottom() ;
  }
} ;

(vs)

class AABB
{
  bool intersects( AABB other )
  {
    return other.left() < right() &&
           left() < other.right() &&

           // +y increases going down
           other.top() < bottom() &&
           top() < other.bottom() ;
  }
} ;

At a glance which AABB does right() refer to? The this adds a bit of a clarifier.

I like this page.

Starts with simple example and moves onto a multi-threaded version. Works out of the box. No 3rd party packages required.

The code will look something like this:

import time
import sys

def do_task():
    time.sleep(1)

def example_1(n):
    for i in range(n):
        do_task()
        print '\b.',
        sys.stdout.flush()
    print ' Done!'

print 'Starting ',
example_1(10)

Or here is example to use threads in order to run the spinning loading bar while the program is running:

import sys
import time
import threading

class progress_bar_loading(threading.Thread):

    def run(self):
            global stop
            global kill
            print 'Loading....  ',
            sys.stdout.flush()
            i = 0
            while stop != True:
                    if (i%4) == 0: 
                        sys.stdout.write('\b/')
                    elif (i%4) == 1: 
                        sys.stdout.write('\b-')
                    elif (i%4) == 2: 
                        sys.stdout.write('\b\\')
                    elif (i%4) == 3: 
                        sys.stdout.write('\b|')

                    sys.stdout.flush()
                    time.sleep(0.2)
                    i+=1

            if kill == True: 
                print '\b\b\b\b ABORT!',
            else: 
                print '\b\b done!',


kill = False      
stop = False
p = progress_bar_loading()
p.start()

try:
    #anything you want to run. 
    time.sleep(1)
    stop = True
except KeyboardInterrupt or EOFError:
         kill = True
         stop = True

string temp = mystring.Replace("\n", " ");

Try

use an id for hidden field and use id of checkbox in javascript.

and change the ClientIDMode="static" too

<input type="hidden" ClientIDMode="static" id="label1" name="label206451" value="0" />

   <script type="text/javascript">

If you want to scroll automatic without show scroll motion then you need to write following code:

mRecyclerView.getLayoutManager().scrollToPosition(position);

If you want to display scroll motion then you need to add following code. =>Step 1: You need to declare SmoothScroller.

RecyclerView.SmoothScroller smoothScroller = new
                LinearSmoothScroller(this.getApplicationContext()) {
                    @Override
                    protected int getVerticalSnapPreference() {
                        return LinearSmoothScroller.SNAP_TO_START;
                    }
                };

=>step 2: You need to add this code any event you want to perform scroll to specific position. =>First you need to set target position to SmoothScroller.

smoothScroller.setTargetPosition(position);

=>Then you need to set SmoothScroller to LayoutManager.

mRecyclerView.getLayoutManager().startSmoothScroll(smoothScroller);

I've encountered this error when my Transaction is nested within another. Is it possible that the stored procedure declares its own transaction or that the calling function declares one?

I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):

aptitude install debian-archive-keyring

In case it is some other keyring you need, check out

apt-cache search keyring | grep debian

My squeeze system shows all these:

debian-archive-keyring       - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring   - GnuPG archive keys of the Debian Edu archive
debian-keyring               - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring     - GnuPG archive keys for the emdebian repository

Had the same problem. I my case the build.gradel(app) was missing buildToolsVersion "27.0.0". So I open a previously working project to determine the version and added this line buildToolsVersion "27.0.0". Now it works fine. Hope this helps.

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

Blocking call: Control returns only when the call completes.

Non blocking call: Control returns immediately. Later OS somehow notifies the process that the call is complete.

Synchronous program: A program which uses Blocking calls. In order not to freeze during the call it must have 2 or more threads (that's why it's called Synchronous - threads are running synchronously).

Asynchronous program: A program which uses Non blocking calls. It can have only 1 thread and still remain interactive.

To elaborate on previous answers about the "every x units" part, here is what I came up with:

# Draw 5 vertical lines
n = 5

# ... evenly spaced between x0 and x1
x0 = 1.0
x1 = 2.0
dx = (x1-x0)/(n-1.0)

# ... each line going from y0 to y1
y0 = 0
y1 = 10

do for [i = 0:n-1] {
    x = x0 + i*dx

}

You can pass it as Action<string> - which means it is a method with a single parameter of type string that doesn't return anything (void) :

public void DoRequest(string request, Action<string> callback)
{
    // do stuff....
    callback("asdf");
}

Using parameter binding is definitely the way to go here. Not only is it very quick to write (just add [Parameter(Mandatory=$true)] above your mandatory parameters), but it's also the only option that you won't hate yourself for later.

More below:

[Console]::ReadLine is explicitly forbidden by the FxCop rules for PowerShell. Why? Because it only works in PowerShell.exe, not PowerShell ISE, PowerGUI, etc.

Read-Host is, quite simply, bad form. Read-Host uncontrollably stops the script to prompt the user, which means that you can never have another script that includes the script that uses Read-Host.

You're trying to ask for parameters.

You should use the [Parameter(Mandatory=$true)] attribute, and correct typing, to ask for the parameters.

If you use this on a [SecureString], it will prompt for a password field. If you use this on a Credential type, ([Management.Automation.PSCredential]), the credentials dialog will pop up, if the parameter isn't there. A string will just become a plain old text box. If you add a HelpMessage to the parameter attribute (that is, [Parameter(Mandatory = $true, HelpMessage = 'New User Credentials')]) then it will become help text for the prompt.

You just want to set the field separator as . using the -F option and print the first field:

$ echo aaa0.bbb.ccc | awk -F'.' '{print $1}'
aaa0

Same thing but using cut:

$ echo aaa0.bbb.ccc | cut -d'.' -f1
aaa0

Or with sed:

$ echo aaa0.bbb.ccc | sed 's/[.].*//'
aaa0

Even grep:

$ echo aaa0.bbb.ccc | grep -o '^[^.]*'
aaa0

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable

jQuery(function(){
    //here it is a closure variable
    var a_href;
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

To make the variable global, one solution is to declare the variable in global scope

var a_href;
jQuery(function(){
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

another is to set the variable as a property of the window object

window.a_href = $(this).attr('href')

Why console printing undefined

You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError

If you want to replace the entire Fragment1 with Fragment2, you need to do it inside MainActivity, by using:

Fragment2 fragment2 = new Fragment2();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(android.R.id.content, fragment2);
fragmentTransaction.commit();

Just put this code inside a method in MainActivity, then call that method from Fragment1.

Works - Add Spacing To Table

#options table {
  border-spacing: 8px;
}

it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.

 btnDate.setOnClickListener(new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                              DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager(), "datePicker");
                            }
                        });

            public static class DatePickerFragment extends DialogFragment
                        implements DatePickerDialog.OnDateSetListener {

                    @Override
                    public Dialog onCreateDialog(Bundle savedInstanceState) {
                        final Calendar c = Calendar.getInstance();
                        int year = c.get(Calendar.YEAR);
                        int month = c.get(Calendar.MONTH);
                        int day = c.get(Calendar.DAY_OF_MONTH);
                        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
                        dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
                        return  dialog;
                    }

                    public void onDateSet(DatePicker view, int year, int month, int day) {
                       btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
                    }
                }

I'd say you're only limited by the total amount of RAM available. Obviously the larger the array the longer operations on it will take.

I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {} statements.

Each time the switch function is the same but the command we supply changes.

do.this <- "T1"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
#########################################################
do.this <- "T2"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
########################################################
do.this <- "T3"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)

Here it is inside a function:

FUN <- function(df, do.this){
    switch(do.this,
        T1={X <- t(df)
            P <- colSums(df)%*%X
        },
        T2={X <- colMeans(df)
            P <- outer(X, X)
        },
        stop("Enter something that switches me!")
    )
    return(P)
}

FUN(mtcars, "T1")
FUN(mtcars, "T2")
FUN(mtcars, "T3")

The suggestion to use listdir is a good one. The direct answer to your question in Python 2 is root, dirs, files = os.walk(dir_name).next().

The equivalent Python 3 syntax is root, dirs, files = next(os.walk(dir_name))

Sort of similar to what mattbtay said, but a few changes. needed html:true.
Put this script on bottom of the page towards close body tag.

<script type="text/javascript">
 $(document).ready(function() {
  $("[rel=drevil]").popover({
      placement : 'bottom', //placement of the popover. also can use top, bottom, left or right
      title : '<div style="text-align:center; color:red; text-decoration:underline; font-size:14px;"> Muah ha ha</div>', //this is the top title bar of the popover. add some basic css
      html: 'true', //needed to show html of course
      content : '<div id="popOverBox"><img src="http://www.hd-report.com/wp-content/uploads/2008/08/mr-evil.jpg" width="251" height="201" /></div>' //this is the content of the html box. add the image here or anything you want really.
});
});
</script>

Then HTML is:

<a href="#" rel="drevil">mischief</a>

Use chrome.tabs.query() like this:

chrome.tabs.query({active: true, lastFocusedWindow: true}, tabs => {
    let url = tabs[0].url;
    // use `url` here inside the callback because it's asynchronous!
});

This requires that you request access to the chrome.tabs API in your extension manifest:

"permissions": [ ...
   "tabs"
]

It's important to note that the definition of your "current tab" may differ depending on your extension's needs.

Setting lastFocusedWindow: true in the query is appropriate when you want to access the current tab in the user's focused window (typically the topmost window).

Setting currentWindow: true allows you to get the current tab in the window where your extension's code is currently executing. For example, this might be useful if your extension creates a new window / popup (changing focus), but still wants to access tab information from the window where the extension was run.

I chose to use lastFocusedWindow: true in this example, because Google calls out cases in which currentWindow may not always be present.

You are free to further refine your tab query using any of the properties defined here: chrome.tabs.query

I think you might be looking for an "anchor" given the example you have.

<a href="#jump">This link will jump to the anchor named jump</a>
<a name="jump">This is where the link will jump to</a>

The focus jQuery method does something different from what you're trying to achieve.

Please check this fiddle and let me know if you get an alert of null value. I have copied your code there and added a couple of alerts. Just like others, I also dont see a null being returned, I get an empty string. Which browser are you using?

The accepted answer (use MockitoJUnitRunner and @InjectMocks) is great. But if you want something a little more lightweight (no special JUnit runner), and less "magical" (more transparent) especially for occasional use, you could just set the private fields directly using introspection.

If you use Spring, you already have a utility class for this : org.springframework.test.util.ReflectionTestUtils

The use is quite straightforward :

ReflectionTestUtils.setField(myLauncher, "myService", myService);

The first argument is your target bean, the second is the name of the (usually private) field, and the last is the value to inject.

If you don't use Spring, it is quite trivial to implement such a utility method. Here is the code I used before I found this Spring class :

public static void setPrivateField(Object target, String fieldName, Object value){
        try{
            Field privateField = target.getClass().getDeclaredField(fieldName);
            privateField.setAccessible(true);
            privateField.set(target, value);
        }catch(Exception e){
            throw new RuntimeException(e);
        }
    }

These instructions work for OSX High Sierra and avoid running gdb as root (yuck!). I recently updated from OSX 10.13.2 to 10.3.3. I think this is when gdb 8.0.1 (installed w/ homebrew) started failing for me.

I had difficulty with other people's instructions. After different instructions, everything was a mess. So I started a fresh. I more or less followed these instructions.

Clean the mess :

1. brew uninstall --force gdb # This deletes _all_ versions of gdb on the machine
2. In Applications -> Utilities -> Keychain Access, I deleted all previous gdb certificates and keys (be sure you know what you're doing here!). It's unclear if this is necessary, but since I'd buggered up trying to create those certificates and keys using other instructions I eliminated them anyways. I had keys and certificates in both login and system.

Now reinstall gdb.

3. brew install gdb
4. Within Keychain Access, go to menu Keychain Access-> Certificate Assistant -> Create a Certificate
5. Check "Let me override defaults" and set

Name : gdb-cert
Identity Type: Self Signed Root
Certificate Type : Code Signing

[X] Let me override defaults

6. On 1st Certificate Information page:

Serial Number : 1
Validity Period (days): 3650

7. On 2nd Certificate Information page, I left all fields blank except those already filled in.

8. On Key Pair Information page, I left the defaults

Key Size : 2048
Algorithm : RSA

9. On Key Usage Extension page, I left the defaults checked.

[X] Include Key Usage Extension
[X] This extension is critical
Capabilities:
[X] Signature

10. On Extended Key Usage Extension page, I left the defaults checked.

[X] Include Extended Key Usage Extension
[X] This extension is critical
Capabilities:
[X] Code Signing

11. On Basic Constraints Extension Page, nothing was checked (default).

12. On Subject Alternate Name Extension page, I left the default checked and didn't add anything else.

[X] Include Subject Alternate Name Extension

13. On Specify a Location for the certificate page, I set

Keychain: System

14. I clicked Create and was prompted for my password.

15. Back in the Keychain Access app, I went to System and right clicked on gdb-cert and under dropdown menu Trust, I changed all the fields to Always Trust.

16. Rebooted computer.

17. At the Terminal, I ran codesign -s gdb-cert /usr/local/bin/gdb. I entered my password when prompted.

18. At the Terminal, I ran echo "set startup-with-shell off" >> ~/.gdbinit

19. I ran gdb myprogram and then start within the gdb console. Here, I believe, it prompted for me for my password. After that, all subsequent runs, it did not prompt for my password.

One the elements are added, use the rules method to add the rules

//bug fixed thanks to @Sparky
$('input[name^="fileupload"]').each(function () {
    $(this).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })
})

Demo: Fiddle

Update

var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile
    var $li = $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" required=""/> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");

    $('#FileUpload' + filenumber).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })

    filenumber++;
    return false;
});

For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:

composer require phpseclib/phpseclib

Next, simply use it as follows:

use phpseclib\Net\SSH2;

// Within a controller for example:
$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
    // Login failed, do something
}

$return_value = $ssh->exec('command');

Every time when screen is rotated, opened activity is finished and onCreate() is called again.

1 . You can do one thing save the state of activity when screen is rotated so that, You can recover all old stuff when activity's onCreate() is called again. Refer this link

2 . If you want to prevent restarting of the activity just place following lines in your manifest.xml file.

  <activity android:name=".Youractivity"
  android:configChanges="orientation|screenSize"/>

Problem with xampp in my case is when specifying a different folder other than htdocs are used, especially with multiple domains and dedicated folders. This is because httpd-ssl.conf is also referencing <VirtualHost>.

To do this rem out the entire <VirtualHost> entry under httpd-ssl.conf

From there, any setting you do in your httpd-vhosts.conf will update as expected both http and https references.

Here is a JQuery&JavaScript solutions to print div as it styles(with internal and external css)

$(document).ready(function() {
            $("#btnPrint").live("click", function () {//$btnPrint is button which will trigger print
                var divContents = $(".order_summery").html();//div which have to print
                var printWindow = window.open('', '', 'height=700,width=900');
                printWindow.document.write('<html><head><title></title>');
                printWindow.document.write('<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.0/css/bootstrap.min.css" >');//external styles
                printWindow.document.write('<link rel="stylesheet" href="/css/custom.css" type="text/css"/>');
                printWindow.document.write('</head><body>');
                printWindow.document.write(divContents);
                printWindow.document.write('</body></html>');
                printWindow.document.close();

                printWindow.onload=function(){
                printWindow.focus();                                         
                printWindow.print();
                printWindow.close();
                }
            });
});

This will print your div in new window.

Button to trigger event

<input type="button" id="btnPrint" value="Print This">

Yes it is possible :) In fact let Internet Explorer do the dirty work for you ;)

TRIED AND TESTED

MY ASSUMPTIONS

1. I am assuming that the html text is in Cell A1 of Sheet1. You can also use a variable instead.
2. If you have a column full of html values, then simply put the below code in a loop

CODE (See NOTE at the end)

Sub Sample()
    Dim Ie As Object
    
    Set Ie = CreateObject("InternetExplorer.Application")
    
    With Ie
        .Visible = False
        
        .Navigate "about:blank"
        
        .document.body.InnerHTML = Sheets("Sheet1").Range("A1").Value
        
        .document.body.createtextrange.execCommand "Copy"
        ActiveSheet.Paste Destination:=Sheets("Sheet1").Range("A1")
        
        .Quit
    End With
End Sub

SNAPSHOT

NOTE: Thanks to @tiQu answer below. The above code will work with new IE if you replace .document.body.createtextrange.execCommand "Copy" with .ExecWB 17, 0: .ExecWB 12, 2 as suggested by him.

Note: It seems this is not the preferred solution because of how the extra line was being added on a Windows system. As stated in the python document:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

Windows is one such platform where that makes a difference. While changing the line terminator as I described below may have fixed the problem, the problem could be avoided altogether by opening the file in binary mode. One might say this solution is more "elegent". "Fiddling" with the line terminator would have likely resulted in unportable code between systems in this case, where opening a file in binary mode on a unix system results in no effect. ie. it results in cross system compatible code.

From Python Docs:

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

Original:

As part of optional paramaters for the csv.writer if you are getting extra blank lines you may have to change the lineterminator (info here). Example below adapated from the python page csv docs. Change it from '\n' to whatever it should be. As this is just a stab in the dark at the problem this may or may not work, but it's my best guess.

>>> import csv
>>> spamWriter = csv.writer(open('eggs.csv', 'w'), lineterminator='\n')
>>> spamWriter.writerow(['Spam'] * 5 + ['Baked Beans'])
>>> spamWriter.writerow(['Spam', 'Lovely Spam', 'Wonderful Spam'])

DISCLAMER: Following code creates different threads for each function.

This might be useful for some of the cases as it is simpler to use. But know that it is not async but gives illusion of async using multiple threads, even though decorator suggests that.

To make any function non blocking, simply copy the decorator and decorate any function with a callback function as parameter. The callback function will receive the data returned from the function.

import asyncio
import requests


def run_async(callback):
    def inner(func):
        def wrapper(*args, **kwargs):
            def __exec():
                out = func(*args, **kwargs)
                callback(out)
                return out

            return asyncio.get_event_loop().run_in_executor(None, __exec)

        return wrapper

    return inner


def _callback(*args):
    print(args)


# Must provide a callback function, callback func will be executed after the func completes execution !!
@run_async(_callback)
def get(url):
    return requests.get(url)


get("https://google.com")
print("Non blocking code ran !!")

To insert inline monospace font in Confluence, surround the text in double curly-braces.

This is an {{example}}.

If you're using Confluence 4.x or higher, you can also just select the "Preformatted" option from the paragraph style menu. Please note that will apply to the entire line.

Full reference here.

The System.out.println(cal_Two.getTime()) invocation returns a Date from getTime(). It is the Date which is getting converted to a string for println, and that conversion will use the default IST timezone in your case.

You'll need to explicitly use DateFormat.setTimeZone() to print the Date in the desired timezone.

EDIT: Courtesy of @Laurynas, consider this:

TimeZone timeZone = TimeZone.getTimeZone("UTC");
Calendar calendar = Calendar.getInstance(timeZone);
SimpleDateFormat simpleDateFormat = 
       new SimpleDateFormat("EE MMM dd HH:mm:ss zzz yyyy", Locale.US);
simpleDateFormat.setTimeZone(timeZone);

System.out.println("Time zone: " + timeZone.getID());
System.out.println("default time zone: " + TimeZone.getDefault().getID());
System.out.println();

System.out.println("UTC:     " + simpleDateFormat.format(calendar.getTime()));
System.out.println("Default: " + calendar.getTime());

To open another modal window in a current opened modal window,
you can use bootstrap-modal

bootstrap-modal DEMO

You kan use https instead of ssh for git clone or git pull or git push

ex:

git clone https://github.com/user/repo.git

Addition to @MarkR answer - one thing to note would be that many PHP frameworks with ORMs would not recognize or use advanced DB setup (foreign keys, cascading delete, unique constraints), and this may result in unexpected behaviour.

For example if you delete a record using ORM, and your DELETE CASCADE will delete records in related tables, ORM's attempt to delete these related records (often automatic) will result in error.

This is a simple example and try to combine it with yours using some modifications. I prefer you set all the images in one array in order to make your code easier to read and shorter:

var myImage = document.getElementById("mainImage");

var imageArray = ["_images/image1.jpg","_images/image2.jpg","_images/image3.jpg",
  "_images/image4.jpg","_images/image5.jpg","_images/image6.jpg"];

var imageIndex = 0; 

function changeImage() {
  myImage.setAttribute("src",imageArray[imageIndex]);
  imageIndex = (imageIndex + 1) % imageArray.length;
}

setInterval(changeImage, 5000);

This what worked for me. set HeaderStyle-Width="5%", in the footer set textbox width Width="15",also set the width of your gridview to 100%. following is the one of the column of my gridview.

    <asp:TemplateField   HeaderText = "sub" HeaderStyle-ForeColor="White" HeaderStyle-Width="5%">
<ItemTemplate>
    <asp:Label ID="sub" runat="server" Font-Size="small" Text='<%# Eval("sub")%>'></asp:Label>
</ItemTemplate> 
 <EditItemTemplate>
    <asp:TextBox ID="txt_sub" runat="server" Text='<%# Eval("sub")%>'></asp:TextBox>
</EditItemTemplate> 
<FooterTemplate>
    <asp:TextBox ID="txt_sub" runat="server" Width="15"></asp:TextBox>
</FooterTemplate>

Of course for very simple comparisons you can always use ngMin/ngMax.

Otherwise, you can go with a custom directive, and there is no need of doing any $watch or $observe or $eval or this fancy $setValidity back and forth. Also, there is no need to hook into the postLink function at all. Try to stay out of the DOM as much as possible, as it is against the angular spirit.

Just use the lifecycle hooks the framework gives you. Add a validator and $validate at each change. Simple as that.

app.directive('sameAs', function() {
  return {
    restrict: 'A',
    require: {
      ngModelCtrl: 'ngModel'
    },
    scope: {
      reference: '<sameAs'
    },
    bindToController: true,
    controller: function($scope) {
      var $ctrl = $scope.$ctrl;

      //add the validator to the ngModelController
      $ctrl.$onInit = function() {
        function sameAsReference (modelValue, viewValue) {
          if (!$ctrl.reference || !modelValue) { //nothing to compare
            return true;
          }
          return modelValue === $ctrl.reference;
        }
        $ctrl.ngModelCtrl.$validators.sameas = sameAsReference;
      };

      //do the check at each change
      $ctrl.$onChanges = function(changesObj) {
        $ctrl.ngModelCtrl.$validate();
      };
    },
    controllerAs: '$ctrl'
  };
});

Your plunker.

The accepted answer to this question is a wonderfully clever use of interactive rebase, but it unfortunately exhibits conflicts if the commit we are trying to change the author of used to be on a branch which was subsequently merged in. More generally, it does not work when handling messy histories.

Since I am apprehensive about running scripts which depend on setting and unsetting environment variables to rewrite git history, I am writing a new answer based on this post which is similar to this answer but is more complete.

The following is tested and working, unlike the linked answer. Assume for clarity of exposition that 03f482d6 is the commit whose author we are trying to replace, and 42627abe is the commit with the new author.

1. Checkout the commit we are trying to modify.

   git checkout 03f482d6
   

2. Make the author change.

   git commit --amend --author "New Author Name <New Author Email>"
   

   Now we have a new commit with hash assumed to be 42627abe.

3. Checkout the original branch.

4. Replace the old commit with the new one locally.

   git replace 03f482d6 42627abe
   

5. Rewrite all future commits based on the replacement.

   git filter-branch -- --all
   

6. Remove the replacement for cleanliness.

   git replace -d 03f482d6
   

7. Push the new history (only use --force if the below fails, and only after sanity checking with git log and/or git diff).

   git push --force-with-lease
   

Instead of 4-6 you can just rebase onto new commit:

git rebase -i 42627abe

Sometimes you may need to plot color precisely based on the x-value case. For example, you may have a dataframe with 3 types of variables and some data points. And you want to do following,

• Plot points corresponding to Physical variable 'A' in RED.
• Plot points corresponding to Physical variable 'B' in BLUE.
• Plot points corresponding to Physical variable 'C' in GREEN.

In this case, you may have to write to short function to map the x-values to corresponding color names as a list and then pass on that list to the plt.scatter command.

x=['A','B','B','C','A','B']
y=[15,30,25,18,22,13]

# Function to map the colors as a list from the input list of x variables
def pltcolor(lst):
    cols=[]
    for l in lst:
        if l=='A':
            cols.append('red')
        elif l=='B':
            cols.append('blue')
        else:
            cols.append('green')
    return cols
# Create the colors list using the function above
cols=pltcolor(x)

plt.scatter(x=x,y=y,s=500,c=cols) #Pass on the list created by the function here
plt.grid(True)
plt.show()

Notice : in case when you just need to change some specific collation use condition like this :

WHERE c.object_id = OBJECT_ID(@table) AND (t.Name LIKE '%char%' OR t.Name LIKE '%text%') 
    AND c.collation_name = 'collation to change'

e.g. NOT the : AND c.collation_name <> @collate

In my case, I had correct / specified collation of some columns and didn't want to change them.

sync method first lists both source and destination paths and copies only differences (name, size etc.).

cp --recursive method lists source path and copies (overwrites) all to the destination path.

If you have possible matches in the destination path, I would suggest sync as one LIST request on the destination path will save you many unnecessary PUT requests - meaning cheaper and possibly faster.

Python's tuples, dicts, and objects offer the programmer a smooth tradeoff between formality and convenience for small data structures ("things"). For me, the choice of how to represent a thing is dictated mainly by how I'm going to use the structure. In C++, it's a common convention to use struct for data-only items and class for objects with methods, even though you can legally put methods on a struct; my habit is similar in Python, with dict and tuple in place of struct.

For coordinate sets, I'll use a tuple rather than a point class or a dict (and note that you can use a tuple as a dictionary key, so dicts make great sparse multidimensional arrays).

If I'm going to be iterating over a list of things, I prefer unpacking tuples on the iteration:

for score,id,name in scoreAllTheThings():
    if score > goodScoreThreshold:
        print "%6.3f #%6d %s"%(score,id,name)

...as the object version is more cluttered to read:

for entry in scoreAllTheThings():
    if entry.score > goodScoreThreshold:
        print "%6.3f #%6d %s"%(entry.score,entry.id,entry.name)

...let alone the dict.

for entry in scoreAllTheThings():
    if entry['score'] > goodScoreThreshold:
        print "%6.3f #%6d %s"%(entry['score'],entry['id'],entry['name'])

If the thing is widely used, and you find yourself doing similar non-trivial operations on it in multiple places in the code, then it's usually worthwhile to make it a class object with appropriate methods.

Finally, if I'm going to be exchanging data with non-Python system components, I'll most often keep them in a dict because that's best suited to JSON serialization.

After spending some time trying to figure out how to recursively add only some of the files, i thought it would be valid to share what did work for me:

FOR /F %F IN ('dir /s /b /a:d') DO svn add --depth=empty "%F"
FOR /F %F IN ('dir /s /b /a *.cs *.csproj *.rpt *.xsd *.resx *.ico *.sql') DO svn add "%F"

Here goes some explanation.

The first command adds all the directories. The second command adds only the files accordingly to the specifed patterns.

Let me give more details:

• FOR: you know, the loop control.
• /F: means take the files and directories (not sure exactly).
• %F: its a variable; it will assume the value of each of the listed files at a time; it could have another one-character-name.
• IN: no need to explain, right?
• ('dir /s /b /a:d'): the DOS command that will list the directories; in my case /s is recursive, /b is to take only the full path, /a:d means only the directory; change it as you wish keeping the parenthesis and apostrophes.
• DO: means that what comes next in the command is what will be executed for each directory
• svn add --depth=empty: it is the desired SVN commando to be run; the depth definition means to add only the directory and not the files inside them.
• "%F": that's how you use the variable defined earlier.

In the second command, the only differences are the dir command and the svn command, i think it is clear enough.

You can do it in this way with Swift 3.0:

let date = Date()
let calendar = Calendar.current
let components = calendar.dateComponents([.year, .month, .day], from: date)

let year =  components.year
let month = components.month
let day = components.day

print(year)
print(month)
print(day)

Make sure to target x86 on your project in Visual Studio. This should fix your trouble.

What worked for me is using sys.path.insert. Then I specified the directory I needed to go. For example I just needed to go up one directory.

import sys
sys.path.insert(0, '../')

There is a really nice, easy to use, lightweight (uses native browser events for detection) plugin for both basic JavaScript and for jQuery that was released this year. It performs perfectly:

https://github.com/sdecima/javascript-detect-element-resize

Since the last update of the xmlhttprequest module was around 2 years ago, in some cases it does not work as expected.

So instead, you can use the xhr2 module. In other words:

var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();

becomes:

var XMLHttpRequest = require('xhr2');
var xhr = new XMLHttpRequest();

But ... of course, there are more popular modules like Axios, because -for example- uses promises:

// Make a request for a user with a given ID
axios.get('/user?ID=12345').then(function (response) {
    console.log(response);
}).catch(function (error) {
    console.log(error);
});

You can do

 document.querySelector("[Span]").textContent = "content_to_display"; 

Use Enum.GetValues to retrieve an array of all values. Then select a random array item.

static Random _R = new Random ();
static T RandomEnumValue<T> ()
{
    var v = Enum.GetValues (typeof (T));
    return (T) v.GetValue (_R.Next(v.Length));
}

Test:

for (int i = 0; i < 10; i++) {
    var value = RandomEnumValue<System.DayOfWeek> ();
    Console.WriteLine (value.ToString ());
}

->

Tuesday
Saturday
Wednesday
Monday
Friday
Saturday
Saturday
Saturday
Friday
Wednesday

EDIT:

Those three different elements all have different rendering rules.

So for:

table#bar you need to set the width to 100% otherwise it will be only be as wide as it determines it needs to be. However, if the table rows total width is greater than the width of bar it will expand to its needed width. IF i recall you can counteract this by setting display: block !important; though its been awhile since ive had to fix that. (im sure someone will correct me if im wrong).

textarea#bar i beleive is a block level element so it will follow the rules the same as the div. The only caveat here is that textarea take an attributes of cols and rows which are measured in character columns. If this is specified on the element it will override the width specified by the css.

input#bar is an inline element, so by default you cant assign it width. However the similar to textarea's cols attribute, it has a size attribute on the element that can determine width. That said, you can always specifiy a width by using display: block; in your css for it. Then it will follow the same rendering rules as the div.

td#foo will be rendered as a table-cell which has some craziness to it. Bottom line here is that for your purposes its going to act just like div#foo as far as restricting the width of its contents. The only issue here is going to be potential unwrappable text in the column somewhere which would make it ignore your width setting. Also all cells in the column are going to get the width of the widest cell.

Thats the default behavior of block level element - ie. if width is auto (the default) then it will be 100% of the inner width of the containing element. so in essence:

#foo {width: 800px;}
#bar {padding-left: 2px; padding-right: 2px; margin-left: 2px; margin-right: 2px;}

will give you exactly what you want.

I also got the error you mention:

CMake Error: CMake can not determine linker language for target:helloworld
CMake Error: Cannot determine link language for target "helloworld".

In my case this was due to having C++ files with the .cc extension.

If CMake is unable to determine the language of the code correctly you can use the following:

set_target_properties(hello PROPERTIES LINKER_LANGUAGE CXX)

The accepted answer that suggests appending the language to the project() statement simply adds more strict checking for what language is used (according to the documentation), but it wasn't helpful to me:

Optionally you can specify which languages your project supports. Example languages are CXX (i.e. C++), C, Fortran, etc. By default C and CXX are enabled. E.g. if you do not have a C++ compiler, you can disable the check for it by explicitly listing the languages you want to support, e.g. C. By using the special language "NONE" all checks for any language can be disabled. If a variable exists called CMAKE_PROJECT__INCLUDE_FILE, the file pointed to by that variable will be included as the last step of the project command.

Most mocking frameworks (Moq and RhinoMocks included) generate proxy classes as a substitute for your mocked class, and override the virtual methods with behavior that you define. Because of this, you can only mock interfaces, or virtual methods on concrete or abstract classes. Additionally, if you're mocking a concrete class, you almost always need to provide a parameterless constructor so that the mocking framework knows how to instantiate the class.

Why the aversion to creating interfaces in your code?

One solution to this would be a list comprehension, with pattern matching inside your tuple:

>>> mylist = [(25,7),(26,9),(55,10)]
>>> [age for (age,person_id) in mylist if person_id == 10]
[55]

Another way would be using map and filter:

>>> map( lambda (age,_): age, filter( lambda (_,person_id): person_id == 10, mylist) )
[55]

Example:

my @a = (undef, undef);
my $size = @a;

warn "Size: " . $#a;   # Size: 1. It's not the size
warn "Size: " . $size; # Size: 2

You can just use an a selector in your stylesheet to define all states of an anchor/hyperlink. For example:

a {
    color: blue;
}

Would override all link styles and make all the states the colour blue.

string str = "string ";
List<string> li_str = new List<string>();
    for (int k = 0; k < 100; i++ )
         li_str.Add(str+k.ToString());
string[] arr_str = li_str.ToArray();

WebClient doesn't have a direct support for form data, but you can send a HTTP post by using the UploadString method:

Using client as new WebClient
    result = client.UploadString(someurl, "param1=somevalue&param2=othervalue")

I've found the answer:

You MUST encode your json like this: {"c":21001,"m":"p"} but not {c:21001,m:"p"} or {'c':21001,'m':'p'}

Thus, the key of a dict must be wrapped in double quotes:", then chrome will preview it as json rather than plain text.

in my case, I was not writing reg_url with :8080 . String reg_url = "http://192.168.29.163:8080/register.php";

var space = $(window).height();
var diff = space - HEIGHT;
var margin = (diff > 0) ? (space - HEIGHT)/2 : 0;
$('#container').css({'margin-top': margin});

Surely using array_map and if using a container implementing ArrayAccess to derive objects is just a smarter, semantic way to go about this?

Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.

For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN() clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.

<?php

$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);

vs

<?php

$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
    $arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);

If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr you could always $arr = array_map and be explicit.

You also need to change the DataSource of the connection string. KELVIN-PC is the name of your local machine and the sql server is running on the default instance.

If you are sure the the server is running as the default instance, you can always use . in the DataSource, eg.

connectionString="Data Source=.;Initial Catalog=LMS;User ID=sa;Password=temperament"

otherwise, you need to specify the name of the instance of the server,

connectionString="Data Source=.\INSTANCENAME;Initial Catalog=LMS;User ID=sa;Password=temperament"

You can try x:Reference trick

<Window ... x:Name="myWindow"><ListBox ItemsSource="{Binding Items, Source={x:Reference myWindow}}" /></Window>

In my case the file is a shell script (*.sh file) meant to deploy our project to a local development server, for my developers.

The shell script should work consistently and may be updated; so I tracked it in the same Git project as the code which the script is meant to deploy.

The shell script runs one executable, and then allows that executable to run; so the script is still running; so my shell still has the script open; so it's locked.

I Ctrl+C'd to kill the script (so now my local dev server is no longer accessible), now I can checkout freely.

A "C-program" is not supposed to be run. It is meant to be compiled into an "executable" program which then can be run from your terminal. You need a compiler for that.

Oh, and the answer to your last question ("Why?") is that the file you are trying to execute doesn't have the executable rights set (which a compiler usually does automatically with the binary, which let's infer that you were trying to run the source code as a script, hence the hint at compiling.)

Your data types are mismatched when you are retrieving the field values.

Also check how you store your enums, default is ORDINAL (numeric value stored in database), but STRING (name of enum stored in database) is also an option. Make sure the Entity in your code and the Model in your database are exactly the same.

I had an enum mismatch. It was set to default (ORDINAL) but the database model was expecting a string VARCHAR2(100char). Solution: @Enumerated(EnumType.STRING)

Use Below code:

private void getCallDeatils() {
    StringBuffer stringBuffer = new StringBuffer();
    Cursor managedCursor = getActivity().managedQuery(CallLog.Calls.CONTENT_URI, null, null, null, null);
    int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
    int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
    int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);

    int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
    stringBuffer.append("Call Deatils");
    while (managedCursor.moveToNext()) {
        String phNumber = managedCursor.getString(number);
        String callType = managedCursor.getString(type);
        String callDate = managedCursor.getString(date);
        Date callDayTime = new Date(Long.valueOf(callDate));
        DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
        String reportDate = df.format(callDayTime);
        String callDuration = managedCursor.getString(duration);
        String dir = null;
        int dircode = Integer.parseInt(callType);
        switch (dircode) {
            case CallLog.Calls.OUTGOING_TYPE:
                dir = "OUTGOING";
                break;

            case CallLog.Calls.INCOMING_TYPE:
                dir = "INCOMING";

                break;

            case CallLog.Calls.MISSED_TYPE:
                dir = "MISSED";
                break;

        }
        stringBuffer.append("\nPhone Number:--- " + phNumber + " \nCall Type:--- " + dir + " \nCall Date:--- " +callDate + " \nCall duration in sec :--- " + callDuration);
        stringBuffer.append("\n----------------------------------");

        logs.add(new LogClass(phNumber,dir,reportDate,callDuration));




    }

What you're actually doing is adding rows. To update the content of existing rows use the UPDATE statement:

UPDATE table SET table_column = 'test';

You can select a code snippet and use right click menu to choose the action "Execute Selection in console".

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

How about alias gcc99= gcc -std=c99?

just add

table.setEnabled(false);

it works fine for me.

SOLUTION FOR Mac

Sample problem but I found my solution with brew.
1. Make sure you have the latest Android Studio installed.
2. Confirm from SDK manager that you have the required SDKs installed.
3. (optional)you could have an AVD installed as well.
4. install Homebrew.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

5. Then run brew update to make sure Homebrew is up to date.

brew update

6. Run brew doctor to make sure everything is safe

brew doctor

7. Add Homebrew's location to your $PATH in your .bash_profile or .zshrc file.

export PATH="/usr/local/bin:$PATH"

8. If you don't have Node already installed, add:

brew install node

9. (Optional) To test out your Node and npm install, try installing Grunt (you might be asked to run with sudo)

npm install -g grunt-cli

10. Install Gradle

brew install gradle

Run: cordova run android --device with you device connected on a Mac and you have gradle working this time.

Usually I find create a custom log function able to save on file, store debug info, and eventually re-print on a common footer.

You can also override common Exception class, so that this type of debugging is semi-automated.

If you want to cut the whitespaces before and behind the word, but keep the middle ones.
You could use:

word = '  Hello World  '
stripped = word.strip()
print(stripped)

In my case the problem was that GNOME keyring was holding an invalid passphrase for the ssh key to be used. After spending indecent amount of time troubleshooting this issue I ran seahorse and found the entry to hold empty string. I can only guess that it was caused by mistyping the passphrase at first use some time earlier, and then probably cancelling the requester or so in order to fall back to command line. Updating the entry with correct passphrase immediately solved the problem. Deleting that entry (from "login" keyring) and reentering passphrase at that first prompt (and checking the appropriate checkbox) solves this too. Now agent gets the correct passphrase from the unlocked at login keyring named "login" and neither asks for passphrase nor "refuses operation" anymore. Of course YMMV.

I do not know, maybe this topic is already solved, but when I have tried recently do this on Windows machine, I have faced with lot of difficulties. So my solution was really simple. I have downloaded this soft http://www.lenzg.net/rinetd/rinetd.html followed their instructions about how to make port forwarding and then successfully my android device connected to make asp.net localhost project and stopped on my breaking point.

my rinetd.conf file:

10.1.1.20 1234 127.0.0.1 1234
10.1.1.20 82 127.0.0.1 82

Where 10.1.1.20 is my localhost ip, 82 and 1234 my ports Also I have craeted bath file for easy life yournameofbathfile.bat, put that file inside rinedfolder. My bath file:

rinetd.exe -c rinetd.conf

After starting this soft, start your aps.net server and try to access from android device or any device in your local network(for example Computer ABC starts putty) and you will see that everything works. No need to go to router setting or do any other complicated things. I hope this will help you. Enjoy.

std::vector<int> first;
std::vector<int> second;

first.insert(first.end(), second.begin(), second.end());

My answer may be late but it worked for me. It may help somebody.

I tried above mentioned steps and that didn't solved the issue.

try thisgit config --global http.sslVerify false

FYI: it looks like you might have an infinite loop in your example...

if cnt > 0 and len(aStr) > 1:
    while cnt > 0:                  
        aStr = aStr[1:]+aStr[0]
        cnt += 1

• a condition of entering the loop is that cnt is greater than 0
• the loop continues to run as long as cnt is greater than 0
• each iteration of the loop increments cnt by 1

The net result is that cnt will always be greater than 0 and the loop will never exit.

I think it's important to note here that onBlur() fires regardless.

This is a helpful thread but the only thing it doesn't clarify is that onBlur() will fire every single time.

onChange() will only fire when the value is changed.

I was using CommonCrypto to generate Hash through the code of MihaelIsaev/HMAC.swift from Easy to use Swift implementation of CommonCrypto HMAC. This implementation is without using Bridging-Header, with creation of Module file.

Now to use AESEncrypt and Decrypt, I directly added the functions inside "extension String {" in HAMC.swift.

func aesEncrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? {
    if let keyData = key.dataUsingEncoding(NSUTF8StringEncoding),
        data = self.dataUsingEncoding(NSUTF8StringEncoding),
        cryptData    = NSMutableData(length: Int((data.length)) + kCCBlockSizeAES128) {

            let keyLength              = size_t(kCCKeySizeAES128)
            let operation: CCOperation = UInt32(kCCEncrypt)
            let algoritm:  CCAlgorithm = UInt32(kCCAlgorithmAES128)
            let options:   CCOptions   = UInt32(options)

            var numBytesEncrypted :size_t = 0

            let cryptStatus = CCCrypt(operation,
                algoritm,
                options,
                keyData.bytes, keyLength,
                iv,
                data.bytes, data.length,
                cryptData.mutableBytes, cryptData.length,
                &numBytesEncrypted)

            if UInt32(cryptStatus) == UInt32(kCCSuccess) {
                cryptData.length = Int(numBytesEncrypted)
                let base64cryptString = cryptData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
                return base64cryptString
            }
            else {
                return nil
            }
    }
    return nil
}

func aesDecrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? {
    if let keyData = key.dataUsingEncoding(NSUTF8StringEncoding),
        data = NSData(base64EncodedString: self, options: .IgnoreUnknownCharacters),
        cryptData    = NSMutableData(length: Int((data.length)) + kCCBlockSizeAES128) {

            let keyLength              = size_t(kCCKeySizeAES128)
            let operation: CCOperation = UInt32(kCCDecrypt)
            let algoritm:  CCAlgorithm = UInt32(kCCAlgorithmAES128)
            let options:   CCOptions   = UInt32(options)

            var numBytesEncrypted :size_t = 0

            let cryptStatus = CCCrypt(operation,
                algoritm,
                options,
                keyData.bytes, keyLength,
                iv,
                data.bytes, data.length,
                cryptData.mutableBytes, cryptData.length,
                &numBytesEncrypted)

            if UInt32(cryptStatus) == UInt32(kCCSuccess) {
                cryptData.length = Int(numBytesEncrypted)
                let unencryptedMessage = String(data: cryptData, encoding:NSUTF8StringEncoding)
                return unencryptedMessage
            }
            else {
                return nil
            }
    }
    return nil
}

The functions were taken from RNCryptor. It was an easy addition in the hashing functions and in one single file "HMAC.swift", without using Bridging-header. I hope this will be useful for developers in swift requiring Hashing and AES Encryption/Decryption.

Example of using the AESDecrypt as under.

 let iv = "AA-salt-BBCCDD--" // should be of 16 characters.
 //here we are convert nsdata to String
 let encryptedString = String(data: dataFromURL, encoding: NSUTF8StringEncoding)
 //now we are decrypting
 if let decryptedString = encryptedString?.aesDecrypt("12345678901234567890123456789012", iv: iv) // 32 char pass key
 {                    
      // Your decryptedString
 }

this would hep you
