Try this

link_to "+ Service", my_services_new_path(:account_id => acct.id)

it will pass the account_id as you want.

In addition to the answers here...

if you are using jquery on the client side, this worked for me:

Java:

@RequestMapping(value = "/ajax/search/sync") 
public String sync(@RequestBody Foo json) {

Jquery (you need to include Douglas Crockford's json2.js to have the JSON.stringify function):

$.ajax({
    type: "post",
    url: "sync", //your valid url
    contentType: "application/json", //this is required for spring 3 - ajax to work (at least for me)
    data: JSON.stringify(jsonobject), //json object or array of json objects
    success: function(result) {
        //do nothing
    },
    error: function(){
        alert('failure');
    }
});

newTitle is a local variable where you create the fields. So when that functions ends, the variable newTitle, does not exist anymore. (The JTextField that was referenced by newTitle does still exist however.)

Thus, increase the scope of the variable, so that you can access it another method.

public SomeFrame extends JFrame {
   JTextField myTitle;//can be used anywhere in this class

   creationOfTheFields()
   {
   //other code
      myTitle = new JTextField("spam");  
      myTitle.setBounds(80, 40, 225, 20);
      options.add(myTitle);
   //blabla other code
   }

   private void New_Name()  
   {  
      this.setTitle(myTitle.getText());  
   } 
}

If your div rule is just div {...}, then #a {...} will be sufficient. If it is more complicated, you need a "more specific" selector, as defined by the CSS specification on specificity. (#a being more specific than div is just single aspect in the algorithm.)

A big part of the REST philosophy is to exploit as many standard features of the HTTP protocol as possible when designing your API. Applying that philosophy to authentication, client and server would utilize standard HTTP authentication features in the API.

Login screens are great for human user use cases: visit a login screen, provide user/password, set a cookie, client provides that cookie in all future requests. Humans using web browsers can't be expected to provide a user id and password with each individual HTTP request.

But for a REST API, a login screen and session cookies are not strictly necessary, since each request can include credentials without impacting a human user; and if the client does not cooperate at any time, a 401 "unauthorized" response can be given. RFC 2617 describes authentication support in HTTP.

TLS (HTTPS) would also be an option, and would allow authentication of the client to the server (and vice versa) in every request by verifying the public key of the other party. Additionally this secures the channel for a bonus. Of course, a keypair exchange prior to communication is necessary to do this. (Note, this is specifically about identifying/authenticating the user with TLS. Securing the channel by using TLS / Diffie-Hellman is always a good idea, even if you don't identify the user by its public key.)

An example: suppose that an OAuth token is your complete login credentials. Once the client has the OAuth token, it could be provided as the user id in standard HTTP authentication with each request. The server could verify the token on first use and cache the result of the check with a time-to-live that gets renewed with each request. Any request requiring authentication returns 401 if not provided.

There is a style that I've created based on dark style from VS 2015 to use on my VS 2010. You can download this style from Dark Style from VS 2015.

After download it, just import through menu Tools -> Import and Export Settings...

something like this :

sudo locate error.log | xargs -IX grep -iH "errorlog" X

or

sudo locate error_log | xargs -IX grep -iH "errorlog" X

or

sudo find / -iname "error?log" 2>/dev/null | xargs -IX grep -iH "errorlog" X

import glob
cv_img = []
for img in glob.glob("Path/to/dir/*.jpg"):
    n= cv2.imread(img)
    cv_img.append(n)`

You seem to be emphasizing the need for a positional association with your data, so wouldn't an associative array be more fitting?

Dictionary<int, string> foo = new Dictionary<int, string>();
foo[2] = "string";

You can run this command for making a factory reset:

killall dropbear uhttpd; sleep 1; mtd -r erase rootfs_data

As of Laravel 5.7 you can pass an array of options to Auth::routes(). You can then disable the register routes with:

Auth::routes(['register' => false]);

You can see how this works from the source code: src/Illuminate/Routing/Router.php.

It depends on what you're trying to achieve after changing the Java file. Until you want to test the maven process, you never need to do anything. Eclipse/MyEclipse will build what is necessary and put the output in the appropriate place within your project. You can also run or deploy it (if it's a web project, for example), without your needing to explicitly do anything with maven. In the end, to install your project in the maven repository, you will need to do a maven install. You may also have other maven goals that you wish to execute, which MyEclipse won't do automatically.

As I say, it depends on what you want to do.

If you haven't created migrations, there are 2 options

1.create the database and tables from application Main:

var context = services.GetRequiredService<YourRepository>();
context.Database.EnsureCreated();

2.create the tables if the database already exists:

var context = services.GetRequiredService<YourRepository>();
context.Database.EnsureCreated();
RelationalDatabaseCreator databaseCreator =
(RelationalDatabaseCreator)context.Database.GetService<IDatabaseCreator>();
databaseCreator.CreateTables();

Thanks to Bubi's answer

No, there isn't.

The closest you can get is:

public static <T> T coalesce(T ...items) {
    for(T i : items) if(i != null) return i;
    return null;
}

For efficient reasons, you can handle the common cases as follows:

public static <T> T coalesce(T a, T b) {
    return a == null ? b : a;
}
public static <T> T coalesce(T a, T b, T c) {
    return a != null ? a : (b != null ? b : c);
}
public static <T> T coalesce(T a, T b, T c, T d) {
    return ...
}

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

I have faced same issue but copying the xampp\mysql\data\ibdata1 was not solved my problem, because I install new version of xampp, if you upgrading your xampp first make backup from all htdocs and mysql folder, in my case I just backup the all xampp to the new folder like old-xampp then install new xampp and then you need do the following steps before starting your new xampp servers:

1. Backup the phpmyadmin folder and ibdata1 from your new installation form this location xampp\mysql\data.
2. Then Go to your old xampp folder old-xampp\mysql\data and copy the ibdata1 file and phpmyadmin from old location.
3. Then open your new xampp folder xampp\mysql\data and past them there.
4. Start the xampp servers.

How about

<button onclick="window.open('http://www.google.com','name','width=200,height=200');">Open</button>

While it's true that id(object) gets the object's address in the default CPython implementation, this is generally useless... you can't do anything with the address from pure Python code.

The only time you would actually be able to use the address is from a C extension library... in which case it is trivial to get the object's address since Python objects are always passed around as C pointers.

In preparation before working offline just run mvn dependency:go-offline

You do not need {{}} in when conditions. What you are searching for is:

- fail: msg="unsupported version"
  when: version not in acceptable_versions

Now I've found the problem.

Removing the obj_exception_throw from my breakpoints solved this. Now it's caught by the @try block and also, NSSetUncaughtExceptionHandler will handle this if a @try block is missing.

The thing on the right of <- is a formula object. It is often used to denote a statistical model, where the thing on the left of the ~ is the response and the things on the right of the ~ are the explanatory variables. So in English you'd say something like "Species depends on Sepal Length, Sepal Width, Petal Length and Petal Width".

The myFormula <- part of that line stores the formula in an object called myFormula so you can use it in other parts of your R code.

Other common uses of formula objects in R

The lattice package uses them to specify the variables to plot.
The ggplot2 package uses them to specify panels for plotting.
The dplyr package uses them for non-standard evaulation.

plt.tick_params(axis='both', which='minor', labelsize=12)

I've used this tool before- although it seems like there needs to be an issue open first, it is super useful and really streamlines workflow if you use github issue tracking. git open-pull and then a pull request is submitted from whatever branch you are on or select. https://github.com/jehiah/git-open-pull

EDIT: Looks like you can create issues on the fly, so this tool is a good solution.

Best way to add custom drawable is:

<RadioButton
    android:id="@+id/radiocar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="@android:color/transparent"
    android:button="@drawable/yourbuttonbackground"
    android:checked="true"
    android:drawableRight="@mipmap/car"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:text="yourtexthere"/>

Shadow overlay by custom drawable is removed here.

@Kwang-Chun Kang Thanks Kang a lot! I found the solution is working and very helpful, it really save my day. For me I am trying to create a React.js component that convert *.xlsx to json object when user upload the excel file to a html input tag. First I need to install XLSX package with:

npm install xlsx --save

Then in my component code, import with:

import XLSX from 'xlsx'

The component UI should look like this:

<input
  accept=".xlsx"
  type="file"
  onChange={this.fileReader}
/>

It calls a function fileReader(), which is exactly same as the solution provided. To learn more about fileReader API, I found this blog to be helpful: https://blog.teamtreehouse.com/reading-files-using-the-html5-filereader-api

You can use break which jumps out of the closest enclosing loop, or you can just directly return true

The advantage of a wordier approach comes when your code is inside a 300,000 line project.

Using the action, as you have, there is no way to tell me what bool, int, and Blah are. If your action passed an object that defined the parameters then ok.

Using an EventHandler that wanted an EventArgs and if you would complete your DiagnosticsArgs example with getters for the properties that commented their purpose then you application would be more understandable. Also, please comment or fully name the arguments in the DiagnosticsArgs constructor.

For small functions like this you could just count by hand how many hops it is to the target, from the instruction under the branch instruction. If it branches backwards make that hop number negative. if that number doesn't require all 16 bits, then for every number to the left of the most significant of your hop number, make them 1's, if the hop number is positive make them all 0's Since most branches are close to they're targets, this saves you a lot of extra arithmetic for most cases.

Ajax call error handler will be triggered if the call itself fails.

You are probably trying to get the error from server in case login credentials do not go through. In that case, you need to inspect the server response json object and display appropriate message.

e.preventDefault();
$.ajax(
{
    type: 'POST',
    url: requestURI,
    data: $(formLogin).serialize(),
    dataType: 'json',
    success: function(result){
        if(result.hasError == true)
        {
            if(result.error_code == 'AUTH_FAILURE')
            {
                //wrong password
                console.log('Recieved authentication error');
                $('#login_errors_auth').fadeIn();
            }
            else
            {
                //generic error here
                $('#login_errors_unknown').fadeIn();
            }
        }
    }
});

Here, "result" is the json object returned form the server which could have a structure like:

$return = array(
        'hasError' => !$validPassword,
        'error_code' => 'AUTH_FAILURE'
);
die(jsonEncode($return));

You can disable certificate checking globally - no matter which package you are using for making requests - like this:

// Disable certificate errors globally
// (ES6 imports (eg typescript))
//
import * as https from 'https'
https.globalAgent.options.rejectUnauthorized = false

Or

// Disable certificate errors globally
// (vanilla nodejs)
//
require('https').globalAgent.options.rejectUnauthorized = false

Of course you shouldn't do this - but it's certainly handy for debugging and/or very basic scripting where you absolutely don't care about certificates being validated correctly.

Change the start field in package.json from

"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" "

to

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "

A quick grep of the libstd++ code base revealed the following two usages of __gx_personality_v0:

In libsupc++/unwind-cxx.h

// GNU C++ personality routine, Version 0.                                      
extern "C" _Unwind_Reason_Code __gxx_personality_v0
     (int, _Unwind_Action, _Unwind_Exception_Class,
      struct _Unwind_Exception *, struct _Unwind_Context *);

In libsupc++/eh_personality.cc

#define PERSONALITY_FUNCTION    __gxx_personality_v0
extern "C" _Unwind_Reason_Code
PERSONALITY_FUNCTION (int version,
                      _Unwind_Action actions,
                      _Unwind_Exception_Class exception_class,
                      struct _Unwind_Exception *ue_header,
                      struct _Unwind_Context *context)
{
  // ... code to handle exceptions and stuff ...
}

(Note: it's actually a little more complicated than that; there's some conditional compilation that can change some details).

So, as long as your code isn't actually using exception handling, defining the symbol as void* won't affect anything, but as soon as it does, you're going to crash - __gxx_personality_v0 is a function, not some global object, so trying to call the function is going to jump to address 0 and cause a segfault.

Convert your number to a Numeric or Decimal.

Replace your query with the following.

Sql server

Select Convert(Numeric(38, 2), Minutes/60.0) from ....

MySql:

Select Convert(Minutes/60.0, Decimal(65, 2)) from ....

The Cast function is a wrapper for the Convert function. Couple that with SQL being an interpreted language and the result is that even though the two functions produce the same results, there is slightly more going on behind the scenes in the Cast function. Using the Convert function is a small saving, but small savings multiply. The parameters for Numeric and Decimal (38, 2) and (65, 2) represent the maximum precision level and decimal places to use.

There are two main differences.

Accessing the association sides

The first one is related to how you will access the relationship. For a unidirectional association, you can navigate the association from one end only.

So, for a unidirectional @ManyToOne association, it means you can only access the relationship from the child side where the foreign key resides.

If you have a unidirectional @OneToMany association, it means you can only access the relationship from the parent side which manages the foreign key.

For the bidirectional @OneToMany association, you can navigate the association in both ways, either from the parent or from the child side.

You also need to use add/remove utility methods for bidirectional associations to make sure that both sides are properly synchronized.

Performance

The second aspect is related to performance.

1. For @OneToMany, unidirectional associations don't perform as well as bidirectional ones.
2. For @OneToOne, a bidirectional association will cause the parent to be fetched eagerly if Hibernate cannot tell whether the Proxy should be assigned or a null value.
3. For @ManyToMany, the collection type makes quite a difference as Sets perform better than Lists.

Referencing Qwerty's answer, if the destRow isnot null, sheet.shiftRows() will change the destRow's reference to the next row; so we should always create a new row:

if (destRow != null) {
  sheet.shiftRows(destination, sheet.getLastRowNum(), 1);
}
destRow = sheet.createRow(destination);

You can use RecyclerView in the support library. RecyclerView is a generalized version of ListView that supports:

• A layout manager for positioning items
• Default animations for common item operations

"On Windows and Mac OS X, the CPython installers now default to installing pip along with CPython itself (users may opt out of installing it during the installation process). Window users will need to opt in to the automatic PATH modifications to have pip available from the command line by default, otherwise it can still be accessed through the Python launcher for Windows as py -m pip."

Have you tried it?

MarkerImage has been deprecated for Icon

Until version 3.10 of the Google Maps JavaScript API, complex icons were defined as MarkerImage objects. The Icon object literal was added in 3.10, and replaces MarkerImage from version 3.11 onwards. Icon object literals support the same parameters as MarkerImage, allowing you to easily convert a MarkerImage to an Icon by removing the constructor, wrapping the previous parameters in {}'s, and adding the names of each parameter.

Phillippe's code would now be:

 var icon = {
     url: "../res/sit_marron.png", // url
     scaledSize: new google.maps.Size(width, height), // size
     origin: new google.maps.Point(0,0), // origin
     anchor: new google.maps.Point(anchor_left, anchor_top) // anchor 
 };

 position = new google.maps.LatLng(latitud,longitud)
 marker = new google.maps.Marker({
  position: position,
  map: map,
  icon: icon
 });

I face the same issue. After debug I fixed the same. if the column name in your sql query has multiple times then this issue occur. Hence use alias in sql query to differ the column name. Ex: The below query will work proper in sql query but create issue in SSRS report:

Select P.ID, P.FirstName, P.LastName, D.ID, D.City, D.Area, D.Address From PersonalDetails P Left Join CommunicationDetails D On P.ID = D.PersonalDetailsID

Reason : ID has mentioned twice (Multiple Times)

Correct Query:

Select P.ID As PersonalDetailsID, P.FirstName, P.LastName, D.ID, D.City, D.Area, D.Address From PersonalDetails P Left Join CommunicationDetails D On P.ID = D.PersonalDetailsID

This answer was written in 2010. The API it uses has since been retired. It is kept for historical interest only.

Search for it.

Make sure include_entities is set to true to get hashtag results. See Tweet Entities

Returns 5 mixed results with Twitter.com user IDs plus entities for the term "blue angels":

GET http://search.twitter.com/search.json?q=blue%20angels&rpp=5&include_entities=true&with_twitter_user_id=true&result_type=mixed

Essentially, and as-noted by @kevin-b:

// find('#id')
angular.element(document.querySelector('#id'))

//find('.classname'), assumes you already have the starting elem to search from
angular.element(elem.querySelector('.classname'))

Note: If you're looking to do this from your controllers you may want to have a look at the "Using Controllers Correctly" section in the developers guide and refactor your presentation logic into appropriate directives (such as <a2b ...>).

That's the HTML data attribute. See this for more detail: http://html5doctor.com/html5-custom-data-attributes/

Basically it's just a container of your custom data while still making the HTML valid. It's data- plus some unique identifier.

There is a new function in C standard for getting a line without specifying its size. getline function allocates string with required size automatically so there is no need to guess about string's size. The following code demonstrate usage:

#include <stdio.h>
#include <stdlib.h>


int main(void)
{
    char *line = NULL;
    size_t len = 0;
    ssize_t read;

    while ((read = getline(&line, &len, stdin)) != -1) {
        printf("Retrieved line of length %zu :\n", read);
        printf("%s", line);
    }

    if (ferror(stdin)) {
        /* handle error */
    }

    free(line);
    return 0;
}

Dot is a dereference operator and used to connect the structure variable for a particular record of structure. Eg :

struct student
    {
      int s.no;
      Char name [];
      int age;
    } s1,s2;

main()
    {
      s1.name;
      s2.name;
    }

In such way we can use a dot operator to access the structure variable

I hope following program will solve your problem

String dateStr = "Mon Jun 18 00:00:00 IST 2012";
DateFormat formatter = new SimpleDateFormat("E MMM dd HH:mm:ss Z yyyy");
Date date = (Date)formatter.parse(dateStr);
System.out.println(date);        

Calendar cal = Calendar.getInstance();
cal.setTime(date);
String formatedDate = cal.get(Calendar.DATE) + "/" + (cal.get(Calendar.MONTH) + 1) + "/" +         cal.get(Calendar.YEAR);
System.out.println("formatedDate : " + formatedDate);    

After checking all of these answers above without luck, the folling code worked for me to solve the problem:

$(".ui-dialog").dialog("close");

Maybe this will be also a good try if you seek for alternatives.

Here are the steps to install JSToolNPP plugin on your Notepad++.

1. Download 64bit version from Sourceforge or the 32bit version if you are on a 32-bit OS.

   64bit - JSToolNPP.1.21.0.uni.64.zip: Download from SourceForget.net
   

2. Notepad++ before installation

3. Unzip the downloaded JSToolNPP.1.21.0.uni.64 and copy the JSMinNPP.dll and place it under C:\Program Files\Notepad++\plugins.

4. Close Notepad++ and reopen it. If you have downloaded an incompatible dll, then it will complain, else it will open successfully. If it complains about incompatibility, go back to STEP 1 and download the correct bit version as per your OS. Check Plugins in Notepad++.

5. Paste a sample unformatted but valid JSON data in Notepad++.

6. Select all text in Notepad++ (CTRL+A) and format using Plugins -> JSTool -> JSFormat.

NOTE: On side note, if you do not want to install any plugins like this, I would recommend using the following 2 best online formatters.

• https://jsonformatter.curiousconcept.com/
• https://jsonformatter.org/

With cache(), you use only the default storage level :

• MEMORY_ONLY for RDD
• MEMORY_AND_DISK for Dataset

With persist(), you can specify which storage level you want for both RDD and Dataset.

From the official docs:

• You can mark an RDD to be persisted using the persist() or cache() methods on it.
• each persisted RDD can be stored using a different storage level
• The cache() method is a shorthand for using the default storage level, which is StorageLevel.MEMORY_ONLY (store deserialized objects in memory).

Use persist() if you want to assign a storage level other than :

• MEMORY_ONLY to the RDD
• or MEMORY_AND_DISK for Dataset

Interesting link for the official documentation : which storage level to choose

both your conditions are the same:

if(s < f) {     calc = f - s;     n = s; }else if(f > s){     calc =  s - f;     n = f;  } 

so

if(s < f)   

and

}else if(f > s){ 

are the same

change to

}else if(f < s){ 

I also faced the similar problem. I googled but couldn't find the solution. So I tried on my own and here is my solution.

Open you solution file in notepad. Make 2 changes

1. Replace "Format Version 12.00" with "Format Version 11.00" (without quotes.)
2. Replace "# Visual Studio 2012" with "# Visual Studio 2010" (without quotes.)

Hope this helps u as well..........

First change the array to a string by using implode() function. E.g $number=array(1,2,3,4,5,...); $stringofnumber=implode("|",$number); then pass the string to a session. e.g $_SESSION['string']=$stringofnumber; so when you go to the page where you want to use the array, just explode your string. e.g $number=explode("|", $_SESSION['string']); finally number is your array but remember to start array on the of each page.

It is possible with CSS3 :

#myDiv {
    -webkit-filter: blur(20px);
    -moz-filter: blur(20px);
    -o-filter: blur(20px);
    -ms-filter: blur(20px);
    filter: blur(20px);
    opacity: 0.4;
}

Example here => jsfiddle

The easiest way is:

File.WriteAllText(path, string.Empty)

However, I recommend you use FileStream because the first solution can throw UnauthorizedAccessException

using(FileStream fs = File.Open(path,FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
     lock(fs)
     {
          fs.SetLength(0);
     }
}

Without knowing the ID of the DIV I think you could select the IMG like this:

$("#"+$(this).attr("id")+" img:first")

Both of these should work:

df.isnull().sum()
df.isna().sum()

DataFrame methods isna() or isnull() are completely identical.

Note: Empty strings '' is considered as False (not considered NA)

KeyedCollection works like dictionary and is serializable.

First create a class containing key and value:

/// <summary>
/// simple class
/// </summary>
/// <remarks></remarks>
[Serializable()]
public class cCulture
{
    /// <summary>
    /// culture
    /// </summary>
    public string culture;

    /// <summary>
    /// word list
    /// </summary>
    public List<string> list;

    /// <summary>
    /// status
    /// </summary>
    public string status;
}

then create a class of type KeyedCollection, and define a property of your class as key.

/// <summary>
/// keyed collection.
/// </summary>
/// <remarks></remarks>
[Serializable()]
public class cCultures : System.Collections.ObjectModel.KeyedCollection<string, cCulture>
{

Usefull to serialize such type of datas.

I accidentally turned on offline mode.

if you did a git add and you haven't pushed anything yet, you just have to do this to unstage it from your commit.

git reset HEAD <file>

if you have multiple parameters use the syntax as below. I have a bat file with script as below:

start "dummyTitle" [/options] D:\path\ProgramName.exe Param1 Param2 Param3 
start "dummyTitle" [/options] D:\path\ProgramName.exe Param4 Param5 Param6 

This will open multiple consoles.

I like Stefan’s answer (Sep 11 ’13) but would like to make it a bit stronger:

If the vector ends with a null terminator, you should not use (v.begin(), v.end()): you should use v.data() (or &v[0] for those prior to C++17).

If v does not have a null terminator, you should use (v.begin(), v.end()).

If you use begin() and end() and the vector does have a terminating zero, you’ll end up with a string "abc\0" for example, that is of length 4, but should really be only "abc".

Taking it further you could even parse on the fly

e.g.

& "my.exe" | %{
    if ($_ -match 'OK')
    { Write-Host $_ -f Green }
    else if ($_ -match 'FAIL|ERROR')
    { Write-Host $_ -f Red }
    else 
    { Write-Host $_ }
}

You will need to subscribe to your observables:

this.CountryService.GetCountries()
    .subscribe(countries => {
        this.myGridOptions.rowData = countries as CountryData[]
    })

And, in your html, wherever needed, you can pass the async pipe to it.

@SafeVarargs does not prevent it from happening, however it mandates that the compiler is stricter when compiling code that uses it.

http://docs.oracle.com/javase/7/docs/api/java/lang/SafeVarargs.html explains this in futher detail.

Heap pollution is when you get a ClassCastException when doing an operation on a generic interface and it contains another type than declared.

A little help:

// an anonymous function_x000D_
  _x000D_
(function () { console.log('allo') });_x000D_
_x000D_
// a self invoked anonymous function_x000D_
_x000D_
(function () { console.log('allo') })();_x000D_
  _x000D_
// a self invoked anonymous function with a parameter called "$"_x000D_
  _x000D_
var jQuery = 'I\'m not jQuery.';_x000D_
_x000D_
(function ($) { console.log($) })(jQuery);

You can also left pad with zeros. For example if you want number to have 9 characters length, left padded with zeros use:

print('{:09.3f}'.format(number))

Thus, if number = 4.656, the output is: 00004.656

For your example the output will look like this:

numbers  = [23.2300, 0.1233, 1.0000, 4.2230, 9887.2000]
for x in numbers: 
    print('{:010.4f}'.format(x))

prints:

00023.2300
00000.1233
00001.0000
00004.2230
09887.2000

One example where this may be useful is when you want to properly list filenames in alphabetical order. I noticed in some linux systems, the number is: 1,10,11,..2,20,21,...

Thus if you want to enforce the necessary numeric order in filenames, you need to left pad with the appropriate number of zeros.

Swift 2.0 version:

func setTorchLevel(torchLevel: Float)
{
    self.captureSession?.beginConfiguration()
    defer {
        self.captureSession?.commitConfiguration()
    }

    if let device = backCamera?.device where device.hasTorch && device.torchAvailable {
        do {
            try device.lockForConfiguration()
            defer {
                device.unlockForConfiguration()
            }

            if torchLevel <= 0.0 {
                device.torchMode = .Off
            }
            else if torchLevel >= 1.0 {
                try device.setTorchModeOnWithLevel(min(torchLevel, AVCaptureMaxAvailableTorchLevel))
            }
        }
        catch let error {
            print("Failed to set up torch level with error \(error)")
            return
        }
    }
}

StringBuilder sb = new StringBuilder();
sb.append("abcdef");
sb.deleteCharAt(sb.length() - 1);
assertEquals("abcde",sb.toString());
// true

Simply set height of the select tag

select{
    height: 30px;

Based on the existing answers, here's a step-by-step guide to sending automated e-mails over SMTP, using a GMail account, from the command line, without disclosing the password.

Requirements

First, install the following software packages:

• Expect
• OpenSSL
• Core Utils (base64)

These instructions assume a Linux operating system, but should be reasonably easy to port to Windows (via Cygwin or native equivalents), or other operating system.

Authentication

Save the following shell script as authentication.sh:

#!/bin/bash

# Asks for a username and password, then spits out the encoded value for
# use with authentication against SMTP servers.

echo -n "Email (shown): "
read email
echo -n "Password (hidden): "
read -s password
echo

TEXT="\0$email\0$password"

echo -ne $TEXT | base64

Make it executable and run it as follows:

chmod +x authentication.sh
./authentication.sh

When prompted, provide your e-mail address and password. This will look something like:

Email (shown): [email protected]
Password (hidden): 
AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==

Copy the last line (AGJ...==), as this will be used for authentication.

Notification

Save the following expect script as notify.sh (note the first line refers to the expect program):

#!/usr/bin/expect

set address "[lindex $argv 0]"
set subject "[lindex $argv 1]"
set ts_date "[lindex $argv 2]"
set ts_time "[lindex $argv 3]"

set timeout 10
spawn openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof 

expect "220" {
  send "EHLO localhost\n"

  expect "250" {
    send "AUTH PLAIN YOUR_AUTHENTICATION_CODE\n"

    expect "235" {
      send "MAIL FROM: <YOUR_EMAIL_ADDRESS>\n"

      expect "250" {
        send "RCPT TO: <$address>\n"

        expect "250" {
          send "DATA\n"

          expect "354" {
            send "Subject: $subject\n\n"
            send "Email sent on $ts_date at $ts_time.\n"
            send "\n.\n"

            expect "250" {
                send "quit\n"
            }
          }
        }
      }
    }
  }
}

Make the following changes:

1. Paste over YOUR_AUTHENTICATION_CODE with the authentication code generated by the authentication script.
2. Change YOUR_EMAIL_ADDRESS with the e-mail address used to generate the authentication code.
3. Save the file.

For example (note the angle brackets are retained for the e-mail address):

send "AUTH PLAIN AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==\n"
send "MAIL FROM: <[email protected]>\n"

Lastly, make the notify script executable as follows:

chmod +x notify.sh

Send E-mail

Send an e-mail from the command line as follows:

./notify.sh [email protected] "Command Line" "March 14" "15:52"

Here I came up with universal method to navigate from any place to root.

1. You create a new Class file with this class, so that it's accessible from anywhere in your project:

   import UIKit
   
   class SharedControllers
   {
       static func navigateToRoot(viewController: UIViewController)
       {
           var nc = viewController.navigationController
   
           // If this is a normal view with NavigationController, then we just pop to root.
           if nc != nil
           {
               nc?.popToRootViewControllerAnimated(true)
               return
           }
   
           // Most likely we are in Modal view, so we will need to search for a view with NavigationController.
           let vc = viewController.presentingViewController
   
           if nc == nil
           {
               nc = viewController.presentingViewController?.navigationController
           }
   
           if nc == nil
           {
               nc = viewController.parentViewController?.navigationController
           }
   
           if vc is UINavigationController && nc == nil
           {
               nc = vc as? UINavigationController
           }
   
           if nc != nil
           {
               viewController.dismissViewControllerAnimated(false, completion:
                   {
                       nc?.popToRootViewControllerAnimated(true)
               })
           }
       }
   }
   

2. Usage from anywhere in your project:

   {
       ...
       SharedControllers.navigateToRoot(self)
       ...
   }
   

Thanks Guillermo Hernandez, I created a variation of your code that works. I added the namespaces in this code for reference.

System.Reflection.Assembly theAsm = Assembly.LoadFrom("My.dll");
// Get a stream to the embedded resource
System.IO.Stream stream = theAsm.GetManifestResourceStream(@"picture.png");

// Here is the most important part:
System.Windows.Media.Imaging.BitmapImage bmi = new BitmapImage();
bmi.BeginInit();
bmi.StreamSource = stream;
bmi.EndInit();

I had the same problem.

In my case, the problem was in public int? CreditLimitBasedOn { get; set; } property I had.

my JSON had the value "CreditLimitBasedOn":true when It should contain an integer. This property prevented the whole object being deserialized on my api method.

I prefer style which allows dry run mode (without | sh) :

cat a.txt | xargs -I % echo "command1; command2; ... " | sh

Works with pipes too:

cat a.txt | xargs -I % echo "echo % | cat " | sh

Type .exit in command prompt window, It terminates the node repl.

I am not sure about the browser compatibility

word-break: break-all;

Also you can use the <wbr> tag

<wbr> (word break) means: "The browser may insert a line break here, if it wishes." It the browser does not think a line break necessary nothing happens.

I would like this in following way:

    def product_list(p):
          total =1 #critical step works for all list
          for i in p:
             total=total*i # this will ensure that each elements are multiplied by itself
          return total
   print product_list([2,3,4,2]) #should print 48

import difflib
f=open('a.txt','r')  #open a file
f1=open('b.txt','r') #open another file to compare
str1=f.read()
str2=f1.read()
str1=str1.split()  #split the words in file by default through the spce
str2=str2.split()
d=difflib.Differ()     # compare and just print
diff=list(d.compare(str2,str1))
print '\n'.join(diff)

You can use parseInt() but, as mentioned, the radix (base) should be specified:

x = parseInt(x, 10);
y = parseInt(y, 10);

10 means a base-10 number.

See this link for an explanation of why the radix is necessary.

Pass java.text.Collator.getInstance() to Collections.sort method ; it will sort Alphabetically while ignoring case sensitive.

        ArrayList<String> myArray = new ArrayList<String>();
        myArray.add("zzz");
        myArray.add("xxx");
        myArray.add("Aaa");
        myArray.add("bb");
        myArray.add("BB");
        Collections.sort(myArray,Collator.getInstance());

You can try:

select(data, matches("search_string"))

It is more general than contains - you can use regex (e.g. "one_string|or_the_other").

For more examples, see: http://rpackages.ianhowson.com/cran/dplyr/man/select.html.

This can happen with a 401 http response if using NSURLConnection.

See NSURLConnection returning error instead of response for 401

Seems like one of your values, with a property key of 'value' is undefined. Test that i1, i2and __i are defined before executing the if statements:

var i1 = document.getElementById('i1');
var i2 = document.getElementById('i2');
var __i = {'user' : document.getElementsByName("username")[0], 'pass' : document.getElementsByName("password")[0] };
if(i1 && i2 && __i.user && __i.pass)
{
    if(  __i.user.value.length >= 1 ) { i1.value = ''; } else { i1.value = 'Acc'; }

    if(  __i.pass.value.length >= 1 ) { i2.value = ''; } else { i2.value = 'Pwd'; }
}

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

You have two root elements in your template.

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

And you need one.

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

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

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

Isolation level defines how the changes made to some data repository by one transaction affect other simultaneous concurrent transactions, and also how and when that changed data becomes available to other transactions. When we define a transaction using the Spring framework we are also able to configure in which isolation level that same transaction will be executed.

@Transactional(isolation=Isolation.READ_COMMITTED)
public void someTransactionalMethod(Object obj) {

}

READ_UNCOMMITTED isolation level states that a transaction may read data that is still uncommitted by other transactions.

READ_COMMITTED isolation level states that a transaction can't read data that is not yet committed by other transactions.

REPEATABLE_READ isolation level states that if a transaction reads one record from the database multiple times the result of all those reading operations must always be the same.

SERIALIZABLE isolation level is the most restrictive of all isolation levels. Transactions are executed with locking at all levels (read, range and write locking) so they appear as if they were executed in a serialized way.

Propagation is the ability to decide how the business methods should be encapsulated in both logical or physical transactions.

Spring REQUIRED behavior means that the same transaction will be used if there is an already opened transaction in the current bean method execution context.

REQUIRES_NEW behavior means that a new physical transaction will always be created by the container.

The NESTED behavior makes nested Spring transactions to use the same physical transaction but sets savepoints between nested invocations so inner transactions may also rollback independently of outer transactions.

The MANDATORY behavior states that an existing opened transaction must already exist. If not an exception will be thrown by the container.

The NEVER behavior states that an existing opened transaction must not already exist. If a transaction exists an exception will be thrown by the container.

The NOT_SUPPORTED behavior will execute outside of the scope of any transaction. If an opened transaction already exists it will be paused.

The SUPPORTS behavior will execute in the scope of a transaction if an opened transaction already exists. If there isn't an already opened transaction the method will execute anyway but in a non-transactional way.

There are three parts to the answer

1. Get the Unicode for each character
2. Determine if it is in the Cyrillic Page
3. Convert to Hexadecimal.

To get each character you can iterate through the String using the charAt() or toCharArray() methods.

for( char c : s.toCharArray() )

The value of the char is the Unicode value.

The Cyrillic Unicode characters are any character in the following ranges:

Cyrillic:            U+0400–U+04FF ( 1024 -  1279)
Cyrillic Supplement: U+0500–U+052F ( 1280 -  1327)
Cyrillic Extended-A: U+2DE0–U+2DFF (11744 - 11775)
Cyrillic Extended-B: U+A640–U+A69F (42560 - 42655)

If it is in this range it is Cyrillic. Just perform an if check. If it is in the range use Integer.toHexString() and prepend the "\\u". Put together it should look something like this:

final int[][] ranges = new int[][]{ 
        {  1024,  1279 }, 
        {  1280,  1327 }, 
        { 11744, 11775 }, 
        { 42560, 42655 },
    };
StringBuilder b = new StringBuilder();

for( char c : s.toCharArray() ){
    int[] insideRange = null;
    for( int[] range : ranges ){
        if( range[0] <= c && c <= range[1] ){
            insideRange = range;
            break;
        }
    }

    if( insideRange != null ){
        b.append( "\\u" ).append( Integer.toHexString(c) );
    }else{
        b.append( c );
    }
}

return b.toString();

Edit: probably should make the check c < 128 and reverse the if and the else bodies; you probably should escape everything that isn't ASCII. I was probably too literal in my reading of your question.

Below Test Init will also do the job.

[TestInitialize]
public void TestInit()
{
  HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
  YourControllerToBeTestedController = GetYourToBeTestedController();
}

I hit this error because I was specifying a label attribute in my geom (geom_text) but was specifying a color in the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# don't do this!
ggplot(df, aes(x=V6, y=V1, color=V1)) +
  geom_text(angle=45, label=df$V1, size=2)

To fix this, I just moved the label attribute out of the geom and into the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# do this!
ggplot(df, aes(x=V6, y=V1, color=V1, label=V1)) +
  geom_text(angle=45, size=2)

You can use Reflector and also use Add-In FileGenerator to extract source code into a project.

What worked for me was:

echo "hello world" | rev | cut -c5- | rev
# hello w

But I used it to trim lines in a file so that's why it looks awkward. The real use was:

cat somefile | rev | cut -c5- | rev

cut only gets you as far as trimming from some starting position, which is bad if you need variable length rows. So this solution reverses (rev) the string and now we relate to its ending position, then uses cut as mentioned, and reverses (again, rev) it back to its original order.

input[required]{
    background-image: radial-gradient(#F00 15%, transparent 16%), radial-gradient(#F00 15%, transparent 16%);
    background-size: 1em 1em;
    background-position: right top;
    background-repeat: no-repeat;
}

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

You have two options:

1) Using String.valueOf() method:

int sdRate=5;
text_Rate.setText(String.valueOf(sdRate));  //faster!, recommended! :)

2) adding an empty string:

int sdRate=5;
text_Rate.setText("" + sdRate)); 

Casting is not an option, will throw a ClassCastException

int sdRate=5;
text_Rate.setText(String.valueOf((String)sdRate)); //EXCEPTION!

For production environments you should use Forever.js

It's so util for start and stop node process, you can list apps running too.

I tried many methods including defined here. What I got is,

• Make sure the name of repository is valid. The best way is to copy the link from repository site and paste in git bash.

• Make sure you have commited the selected files.

  git commit -m "Your commit here"
  

• If both steps don't work, try

  git push -u -f origin master

First give the link of logout.php page in that logout button.In that page make the code which is given below:

Here is the code:

<?php
 session_start();
 session_destroy();
?>

When the session has started, the session for the last/current user has been started, so don't need to declare the username. It will be deleted automatically by the session_destroy method.

The CURL extension ext/curl is not installed or enabled in your PHP installation. Check the manual for information on how to install or enable CURL on your system.

Send a ajax request to your server like this in your js and get your result in success function.

jQuery.ajax({
            url: "/rest/abc",
            type: "GET",

            contentType: 'application/json; charset=utf-8',
            success: function(resultData) {
                //here is your json.
                  // process it

            },
            error : function(jqXHR, textStatus, errorThrown) {
            },

            timeout: 120000,
        });

at server side send response as json type.

And you can use jQuery.getJSON for your application.

Here's a library I forked from CodeMonkeysRU.

The reason I forked was because Google requires exponential backoff. I use a redis server to queue messages and resend after a set time.

I've also updated it to support iOS.

A multiple select is really just a select with a multiple attribute. With that in mind, it should be as easy as...

Form::select('sports[]', $sports, null, array('multiple'))

The first parameter is just the name, but post-fixing it with the [] will return it as an array when you use Input::get('sports').

The second parameter is an array of selectable options.

The third parameter is an array of options you want pre-selected.

The fourth parameter is actually setting this up as a multiple select dropdown by adding the multiple property to the actual select element..

The only solution that worked for me and $.each was definitely causing the error. so i used for loop and it's not throwing error anymore.

Example code

     $.ajax({
            type: 'GET',
            url: 'https://example.com/api',
            data: { get_param: 'value' },
            success: function (data) {
                for (var i = 0; i < data.length; ++i) {
                    console.log(data[i].NameGerman);
                }
            }
        });

if it's background, use background-size: cover;

body{_x000D_
    background-image: url('http://i.stack.imgur.com/kx8MT.gif');_x000D_
    background-size: cover;_x000D_
    _x000D_
    _x000D_
    _x000D_
    height: 100vh;_x000D_
    padding:0;_x000D_
    margin:0;_x000D_
}

FileStream fileStream = new FileStream("file.txt", FileMode.Open);
using (StreamReader reader = new StreamReader(fileStream))
{
    string line = reader.ReadLine();
}

Using the System.IO.FileStream and System.IO.StreamReader. You can use System.IO.BinaryReader or System.IO.BinaryWriter as well.

It has been asked in the past, apparently it costs a lot to mobile browsers, so it's been disabled.

Check this comment by @PaulIrish:

Fixed-backgrounds have huge repaint cost and decimate scrolling performance, which is, I believe, why it was disabled.

you can see workarounds to this in this posts:

In Swift:

var uuid: String = NSUUID().UUIDString
println("uuid: \(uuid)")

Solution for Webview!

For PhoneGap-iPhone / PhoneGap-iOS applications, you can disable telephone number detection by adding the following to your project’s application delegate:

// ...

- (void)webViewDidStartLoad:(UIWebView *)theWebView 
{
    // disable telephone detection, basically <meta name="format-detection" content="telephone=no" />
    theWebView.dataDetectorTypes = UIDataDetectorTypeAll ^ UIDataDetectorTypePhoneNumber;

    return [ super webViewDidStartLoad:theWebView ];
}

// ...

As people above have noted you'll either have to recalculate an offset to the stroke's path coordinates or double its width and then mask one side or the other, because not only does SVG not natively support Illustrator's stroke alignment, but PostScript doesn't either.

The specification for strokes in Adobe's PostScript Manual 2nd edition states: "4.5.1 Stroking: The stroke operator draws a line of some thickness along the current path. For each straight or curved segment in the path, stroke draws a line that is centered on the segment with sides parallel to the segment." (emphasis theirs)

The rest of the specification has no attributes for offsetting the line's position. When Illustrator lets you align inside or outside, it's recalculating the actual path's offset (because it's still computationally cheaper than overprinting then masking). The path coordinates in the .ai document are reference, not what gets rastered or exported to a final format.

Because Inkscape's native format is spec SVG, it can't offer a feature the spec lacks.

When you call notify() from an object t, java notifies a particular t.wait() method. But, how does java search and notify a particular wait method.

java only looks into the synchronized block of code which was locked by object t. java cannot search the whole code to notify a particular t.wait().

Old question, but still no good up-to-date answer with insight imo.

As jQuery uses Javascript wording for events and handlers, but does its own undocumented, but different interpretation of those, let me first shed light on the difference from the pure Javascript viewpoint:

• both event pairs
  • the mouse can “jump” from outside/outer elements to inner/innermost elements when moved faster than the browser samples its position
  • any enter/over gets a corresponding leave/out (possibly late/jumpy)
  • events go to the visible element below the pointer (invisible elements can’t be target)
• mouseenter/mouseleave
  • does not bubble (event not useful for delegate handlers)
  • the event registration itself defines the area of observation and abstraction
  • works on the target area, like a park with a pond: the pond is considered part of the park
  • the event is emitted on the target/area whenever the element itself or any descendant directly is entered/left the first time
  • entering a descendant, moving from one descendant to another or moving back into the target does not finish/restart the mouseenter/mouseleave cycle (i.e. no events fire)
  • if you want to observe multiple areas with one handler, register it on each area/element or use the other event pair discussed next
  • descendants of registered areas/elements can have their own handlers, creating an independent observation area with its independent mouseenter/mouseleave event cycles
  • if you think about how a bubbling version of mouseenter/mouseleave could look like, you end up with with something like mouseover/mouseout
• mouseover/mouseout
  • events bubble
  • events fire whenever the element below the pointer changes
    • mouseout on the previously sampled element
    • followed by mouseover on the new element
    • the events don’t “nest”: before e.g. a child is “overed” the parent will be “out”
  • target/relatedTarget indicate new and previous element
  • if you want to watch different areas
    • register one handler on a common parent (or multiple parents, which together cover all elements you want to watch)
    • look for the element you are interested in between the handler element and the target element; maybe $(event.target).closest(...) suits your needs

Not-so-trivial mouseover/mouseout example:

$('.side-menu, .top-widget')
  .on('mouseover mouseout', event => {
    const target = event.type === 'mouseover' ? event.target : event.relatedTarget;
    const thing = $(target).closest('[data-thing]').attr('data-thing') || 'default';
    // do something with `thing`
  });

These days, all browsers support mouseover/mouseout and mouseenter/mouseleave natively. Nevertheless, jQuery does not register your handler to mouseenter/mouseleave, but silently puts them on a wrappers around mouseover/mouseout as the code below exposes.

The emulation is unnecessary, imperfect and a waste of CPU cycles: it filters out mouseover/mouseout events that a mouseenter/mouseleave would not get, but the target is messed. The real mouseenter/mouseleave would give the handler element as target, the emulation might indicate children of that element, i.e. whatever the mouseover/mouseout carried.

For that reason I do not use jQuery for those events, but e.g.:

$el[0].addEventListener('mouseover', e => ...);

const list = document.getElementById('log');
const outer = document.getElementById('outer');
const $outer = $(outer);

function log(tag, event) {
  const li = list.insertBefore(document.createElement('li'), list.firstChild);
  // only jQuery handlers have originalEvent
  const e = event.originalEvent || event;
  li.append(`${tag} got ${e.type} on ${e.target.id}`);
}

outer.addEventListener('mouseenter', log.bind(null, 'JSmouseenter'));
$outer.on('mouseenter', log.bind(null, '$mouseenter'));

div {
  margin: 20px;
  border: solid black 2px;
}

#inner {
  min-height: 80px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<body>
  <div id=outer>
    <ul id=log>
    </ul>
  </div>
</body>

Note: For delegate handlers never use jQuery’s “delegate handlers with selector registration”. (Reason in another answer.) Use this (or similar):

$(parent).on("mouseover", e => {
  if ($(e.target).closest('.gold').length) {...};
});

instead of

$(parent).on("mouseover", '.gold', e => {...});

You can use map. Here is an example implementation:

case 'SOME_ACTION':
   return { 
       ...state, 
       contents: state.contents.map(
           (content, i) => i === 1 ? {...content, text: action.payload}
                                   : content
       )
    }

Simple, you just open klik file -> import -> General -> existing project into workspace -> browse file in your directory.

As said in the post, React is a browser based technology. It only renders a view in an HTML document.

To be able to have access to your "React App", you need to:

1. Bundle your React app in a bundle
2. Have Apache pointing to your html file in your server, and allowing access externally.

You might have all the informations here: https://httpd.apache.org/docs/trunk/getting-started.html for the Apache server, and here to make your javascript bundle https://www.codementor.io/tamizhvendan/beginner-guide-setup-reactjs-environment-npm-babel-6-webpack-du107r9zr

Thanks to Devin, I figured out the solution for my SLIM application with multi domain access.

In htaccess:

SetEnvIf Origin "http(s)?://(www\.)?(allowed.domain.one|allowed.domain.two)$" AccessControlAllowOrigin=$0$1
Header set Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header set Access-Control-Allow-Credentials true

in index.php

// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");         

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
}
// instead of mapping:
$app->options('/(:x+)', function() use ($app) {
    //...return correct headers...
    $app->response->setStatus(200);
});

Even if it is a little bit late, i solved the PATH problem by removing every space.

works for me now.

Seems your initial data contains strings and not numbers. It would probably be best to ensure that the data is already of the required type up front.

However, you can convert strings to numbers like this:

pd.Series(['123', '42']).astype(float)

instead of float(series)

This file will serve you as a good sendfile example : http://tldp.org/LDP/LGNET/91/misc/tranter/server.c.txt

You can use names directly in the read_csv

names : array-like, default None List of column names to use. If file contains no header row, then you should explicitly pass header=None

Cov = pd.read_csv("path/to/file.txt", 
                  sep='\t', 
                  names=["Sequence", "Start", "End", "Coverage"])

Had the same problem. I used table layout at first but the layout kept changing after a button press. Found this page very useful though. http://mobile.tutsplus.com/tutorials/android/android-user-interface-design-creating-a-numeric-keypad-with-gridlayout/

Try this:

echo $array[0]->id;

I have got a prime function which works until (2^61)-1 Here:

from math import sqrt
def isprime(num): num > 1 and return all(num % x for x in range(2, int(sqrt(num)+1)))

Explanation:

The all() function can be redefined to this:

def all(variables):
    for element in variables:
        if not element: return False
    return True

The all() function just goes through a series of bools / numbers and returns False if it sees 0 or False.

The sqrt() function is just doing the square root of a number.

For example:

>>> from math import sqrt
>>> sqrt(9)
>>> 3
>>> sqrt(100)
>>> 10

The num % x part returns the remainder of num / x.

Finally, range(2, int(sqrt(num))) means that it will create a list that starts at 2 and ends at int(sqrt(num)+1)

For more information about range, have a look at this website!

The num > 1 part is just checking if the variable num is larger than 1, becuase 1 and 0 are not considered prime numbers.

I hope this helped :)

It seems that CharEscapers from Google GData-java-client has what you want. It has uriPathEscaper method, uriQueryStringEscaper, and generic uriEscaper. (All return Escaper object which does actual escaping). Apache License.

It was giving 415 Http response Code as error,

So I added

httppost.addHeader("Content-Type", "text/xml; charset=utf-8");

Everything alright now, Http: 200

in standard C, you can use INT_MAX as the maximum 'int' value, this constant must be defined in "limits.h". Similar constants are defined for other types (http://www.acm.uiuc.edu/webmonkeys/book/c_guide/2.5.html), as stated, these constant are implementation-dependent but have a minimum value according to the minimum bits for each type, as specified in the standard.

This question is a bit old, but for those still arriving here now and using react-router 4.3 it's a bug and got fixed in the beta version 4.4.0. Just upgrade your react-router to version +4.4.0. Be aware that it's a beta version at this moment.

The new version 3.0 of the jQuery Bubble Popup plugin supports jQuery v.1.7.2, currently the latest and stable version of the most famous javascript library.

The most interesting feature of the 3.0 version is that You can use together jQuery & Bubble Popup plugin with any other libraries and javascript frameworks like Script.aculo.us, Mootols or Prototype because the plugin is completely encapsulated to prevent incompatibility problems;

jQuery Bubble Popup was tested and supports a lot of known and “unknown” browsers; see the documentation for the complete list.

Like previous versions, jQuery Bubble Popup plugin continues to be released under the MIT license; You are free to use jQuery Bubble Popup in commercial or personal projects as long as the copyright header is left intact.

download the latest version or visit live demos and tutorials at http://www.maxvergelli.com/jquery-bubble-popup/

Old fashioned and big code but efficient as possible:

function replaceLast(origin,text){
    textLenght = text.length;
    originLen = origin.length
    if(textLenght == 0)
        return origin;

    start = originLen-textLenght;
    if(start < 0){
        return origin;
    }
    if(start == 0){
        return "";
    }
    for(i = start; i >= 0; i--){
        k = 0;
        while(origin[i+k] == text[k]){
            k++
            if(k == textLenght)
                break;
        }
        if(k == textLenght)
            break;
    }
    //not founded
    if(k != textLenght)
        return origin;

    //founded and i starts on correct and i+k is the first char after
    end = origin.substring(i+k,originLen);
    if(i == 0)
        return end;
    else{
        start = origin.substring(0,i) 
        return (start + end);
    }
}

Swift 3 solution:

let singleTap = UITapGestureRecognizer(target: self, action:#selector(self.singleTapAction(_:)))
singleTap.numberOfTapsRequired = 1
view.addGestureRecognizer(singleTap)

let doubleTap = UITapGestureRecognizer(target: self, action:#selector(self.doubleTapAction(_:)))
doubleTap.numberOfTapsRequired = 2
view.addGestureRecognizer(doubleTap)

singleTap.require(toFail: doubleTap)

In the code line singleTap.require(toFail: doubleTap) we are forcing the single tap to wait and ensure that the tap event is not a double tap.

There are a bunch of good solutions here but I'd suggest going the other route with this. If searching is the most important thing and the 'secret' property is not used on the view at all; my approach for this would be to use the built-in angular filter with all its benefits and simply map the model to a new array of objects.

Example from the question:

$scope.people = members.map(function(member) { 
                              return { 
                                name: member.name, 
                                phone: member.phone
                              }});

Now, in html simply use the regular filter to search both these properties.

<div ng-repeat="member in people | filter: searchString">

Follow the next steps:

1. Open the app.config and comment on the connection string (save file)
2. Open the edmx (go to properties, the connection string should be blank), close the edmx file again
3. Open the app.config and uncomment the connection string (save file)
4. Open the edmx, go to properties, you should see the connection string uptated!!

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:

var data = context.MyEntities.AsNoTracking().Where(...).ToList();

As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

1 minute googling gave me this result. See the DEMO!

HTML

<form>
    <label for="username">Username:</label>
    <input id="username" name="username" type="text" placeholder="Username" />
    <label for="password">Password:</label>
    <input id="password" name="password" type="password" placeholder="Password" />
    <input id="submit" name="submit" type="submit" value="Login" />
</form>

jQuery

// ----- Setup: Add dummy text field for password and add toggle link to form; "offPage" class moves element off-screen
$('input[type=password]').each(function () {
    var el = $(this),
        elPH = el.attr("placeholder");
    el.addClass("offPage").after('<input class="passText" placeholder="' + elPH + '" type="text" />');
});
$('form').append('<small><a class="togglePassText" href="#">Toggle Password Visibility</a></small>');

// ----- keep password field and dummy text field in sync
$('input[type=password]').keyup(function () {
    var elText = $(this).val();
    $('.passText').val(elText);
});
$('.passText').keyup(function () {
    var elText = $(this).val();
    $('input[type=password]').val(elText);
});

// ----- Toggle link functionality - turn on/off "offPage" class on fields
$('a.togglePassText').click(function (e) {
    $('input[type=password], .passText').toggleClass("offPage");
    e.preventDefault(); // <-- prevent any default actions
});

CSS

.offPage {
    position: absolute;
    bottom: 100%;
    right: 100%;
}

If you pass 0 as the port number to the constructor of ServerSocket, It will allocate a port for you.

Not sure I completely understand the question but:

$(":button.brown").click(function() {
  $(":button.brown.selected").removeClass("selected");
  $(this).addClass("selected");
});

seems to be along the lines of what you want.

I would certainly recommend using classes instead of directly setting CSS, which is problematic for several reasons (eg removing styles is non-trivial, removing classes is easy) but if you do want to go that way:

$("...").css("background", "brown");

But when you want to reverse that change, what do you set it to?

document.getElementById('id1').bgColor = '#00FF00';

seems to work. I don't think .style.backgroundColor does.

If you are using Kotlin and Material Design, you can change color of your MaterialButton like this:

myButton.background.setTintList(ContextCompat.getColorStateList(context, R.color.myColor))

You can improve it even better by creating an extension function for your MaterialButton in order to make you code more readable and your coding little more convenient:

fun MaterialButton.changeColor(color: Int) {
    this.background.setTintList(ContextCompat.getColorStateList(context, color))
}

Then, you can use your function everywhere like this:

myButton.changeColor(R.color.myColor)

1. Using scrollHeight is not only buggy, but doesn't work when your container has a hardcoded height (which is probably most cases, since you wanna get contents height without doing container.height() itself)
2. @shazboticus-s-shazbot solution is good when you can mess around with the container height temporarily / have a hard-coded height.
3. An alternative solution would be:

$('#outer')_x000D_
    // Get children in array format, as we'll be reducing them into a single number_x000D_
    .contents().toArray()_x000D_
    // Filter out text and comment nodes, only allowing tags_x000D_
    .filter(el => el.nodeType === 1)_x000D_
    // Sum up all the children individual heights_x000D_
    .reduce((accumulator, el) => $(el).outerHeight(true) + accumulator, 0);

Of course, this latter alternative only works when #outer doesn't have immediate text childrens that take up space and you want to measure. Those are my 2 cents.

4. If you want to measure unwrapped text, I'd suggest modifying your DOM tree and having an inner <div> of which you can measure easily by doing $('#outer').children().height()

You can associate directly the function object window.destroy to the command attribute of your button:

button = Button (frame, text="Good-bye.", command=window.destroy)

This way you will not need the function close_window to close the window for you.

It's possibly a 32 - 64 bits mismatch.

If you're running on a 64-bit OS, the Assembly RevitAPI may be compiled as 32-bit and your process as 64-bit or "Any CPU".

Or, the RevitAPI is compiled as 64-bit and your process is compiled as 32-bit or "Any CPU" and running on a 32-bit OS.

            System.out.println(x>y ?(x-y)+"":(y-x)+"");
        }
    }
}

This solution is a bit more efficient than the one above because it takes up the 2.128 and this takes 1.308 seconds to solve the problem.

When you already have all the "pieces" you wish to append, there is no point in using StringBuilder at all. Using StringBuilder and string concatenation in the same call as per your sample code is even worse.

This would be better:

return "select id1, " + " id2 " + " from " + " table";

In this case, the string concatenation is actually happening at compile-time anyway, so it's equivalent to the even-simpler:

return "select id1, id2 from table";

Using new StringBuilder().append("select id1, ").append(" id2 ")....toString() will actually hinder performance in this case, because it forces the concatenation to be performed at execution time, instead of at compile time. Oops.

If the real code is building a SQL query by including values in the query, then that's another separate issue, which is that you should be using parameterized queries, specifying the values in the parameters rather than in the SQL.

I have an article on String / StringBuffer which I wrote a while ago - before StringBuilder came along. The principles apply to StringBuilder in the same way though.

Use the range's NumberFormat property to force the format of the range like this:

Sheet1.Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"

Fragments lives within the Activity and has:

• its own lifecycle
• its own layout
• its own child fragments and etc.

Think of Fragments as a sub activity of the main activity it belongs to, it cannot exist of its own and it can be called/reused again and again. Hope this helps :)

this will help all of you to find your own correct details use

npm ls dist-tag

this will then show the correct info so you don't guess the version file location etc

enjoy :)

Image Layer: Repositories are often referred to as images or container images, but actually they are made up of one or more layers. Image layers in a repository are connected together in a parent-child relationship. Each image layer represents changes between itself and the parent layer.

The docker building pattern uses inheritance. It means the version i depends on version i-1. So, we must delete the version i+1 to be able to delete version i. This is a simple dependency.

If you wanna delete all images except the last one (the most updated) and the first (base) then we can export the last (the most updated one) using docker save command as below.

docker save -o <output_file> <your_image-id> | gzip <output_file>.tgz

Then, now, delete all the images using image-id as below.

docker rm -f <image-id i> | docker rm -f <image i-1> | docker rm -f <image-id i-2> ... <docker rm -f <image-id i-k> # where i-k = 1

Now, load your saved tgz image as below.

gzip -c <output_file.tgz> | docker load

see the image-id of your loaded image using docker ps -q. It doesn't have tag and name. You can simply update tag and name as done below.

docker tag <image_id> group_name/name:tag

import os

path = chap_name

if not os.path.exists(path):
    os.makedirs(path)

filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
    temp_file.write(buff)

Key point is to use os.makedirs in place of os.mkdir. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html

Open the file in binary mode as you are storing binary (jpeg) data.

In response to Edit 2, if img_alt sometimes has '/' in it:

img_alt = os.path.basename(img_alt)

In my case, I have Eclipse Maven project. I had the same issue and I posted detailed explanation of the issue and answer here Eclipse Maven - Code Completion fails "This compilation unit is not on the build path of a Java project" and "Failed to Download Index" Error

import subprocess
p = sub.Popen('file yourfile.txt', stdout=sub.PIPE, stderr=sub.PIPE)
output, errors = p.communicate()
print(output)

As Steven pointed out, subprocess is the way. You can get the command output by the way above as this post said

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

Did you try format?

@font-face {
  font-family: 'The name of the Font Family Here';
  src: URL('font.ttf') format('truetype');
}

Read this article: http://css-tricks.com/snippets/css/using-font-face/

Also, might depend on browser as well.

I know this has been answered, but here's mine just because I think case is an under-appreciated tool. (Maybe because people think it is slow, but it's at least as fast as an if, sometimes faster.)

case "$1" in
    0|1) xinput set-prop 12 "Device Enabled" $1 ;;
      *) echo "This script requires a 1 or 0 as first parameter." ;;
esac

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.

However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.

So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.

As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod eliminate information from your input. Suppose you calculate mod 5 and you get 0. What was the input? Was it 0, 5 or 500? You see, you can't really 'go back' in this case.

You could make it into a module and expose your inner function by returning it in an Object.

function outer() { 
    function inner() {
        console.log("hi");
    }
    return {
        inner: inner
    };
}
var foo = outer();
foo.inner();

Just use the method .decode('base64') and go to be happy.

You need, too, to detect the mimetype/extension of the image, as you can save it correctly, in a brief example, you can use the code below for a django view:

def receive_image(req):
    image_filename = req.REQUEST["image_filename"] # A field from the Android device
    image_data = req.REQUEST["image_data"].decode("base64") # The data image
    handler = open(image_filename, "wb+")
    handler.write(image_data)
    handler.close()

And, after this, use the file saved as you want.

Simple. Very simple. ;)

a.button:hover{
    background: #383;  }

works for me but in my case

#buttonClick:hover {
background-color:green;  }

Create the user with a password :

http://www.postgresql.org/docs/current/static/sql-createuser.html

CREATE USER name [ [ WITH ] option [ ... ] ]

where option can be:

      SUPERUSER | NOSUPERUSER
    | CREATEDB | NOCREATEDB
    | CREATEROLE | NOCREATEROLE
    | CREATEUSER | NOCREATEUSER
    | INHERIT | NOINHERIT
    | LOGIN | NOLOGIN
    | REPLICATION | NOREPLICATION
    | CONNECTION LIMIT connlimit
    | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'

    | IN GROUP role_name [, ...]
    | ROLE role_name [, ...]
    | ADMIN role_name [, ...]
    | USER role_name [, ...]
    | SYSID uid

Then grant the user rights on a specific database :

http://www.postgresql.org/docs/current/static/sql-grant.html

Example :

grant all privileges on database db_name to someuser;

There are three approaches

• Use SublimeCodeIntel plug-in

• Use CTags plug-in

• Generate .sublime-completion file manually

Approaches are described in detail in this blog post (of mine): http://opensourcehacker.com/2013/03/04/javascript-autocompletions-and-having-one-for-sublime-text-2/

This

public static bool GetBit(this byte b, int bitNumber) {
   return (b & (1 << bitNumber)) != 0;
}

should do it, I think.

Given just the pointer, you can't. You'll have to keep hold of the length you passed to new[] or, better, use std::vector to both keep track of the length, and release the memory when you've finished with it.

Please click on this link it should work ..

http://www.php-guru.in/2013/html-to-pdf-conversion-in-codeigniter/

Or you can see below

There are number of PHP libraries on the web to convert HTML page to PDF file. They are easy to implement and deploy when you are working on any web application in core PHP. But when we try to integrate this libraries with any framework or template, then it becomes very tedious work if the framework which we are using does not have its own library to integrate it with any PDF library. The same situation came in front of me when there was one requirement to convert HTML page to PDF file and the framework I was using was codeigniter.

I searched on web and got number of PHP libraries to convert HTML page to PDF file. After lot of research and googling I decided to go with TCPDF PHP library to convert HTML page to PDF file for my requirement. I found TCPDf PHP library quite easy to integrate with codeigniter and stated working on it. After successfully completing my integration of codeigniter and TCPDF, I thought of sharing this script on web.

Now, let’s start with implimentation of the code.

Download the TCPDF library code, you can download it from TCPDF website http://www.tcpdf.org/.

Now create “tcpdf” folder in “application/helpers/” directory of your web application which is developed in codeigniter. Copy all TCPDF library files and paste it in “application/helpers/tcpdf/” directory. Update the configuration file “tcpdf_config.php” of TCPDF, which is located in “application/helpers/tcpdf/config” directory, do changes according to your applicatoin requirements. We can set logo, font, font size, with, height, header etc in the cofing file. Give read, write permissions to “cache” folder which is there in tcpdf folder. After defining your directory structure, updating configuration file and assigning permissions, here starts your actual coding part.

Create one PHP helper file in “application/helpers/” directory of codeigniter, say “pdf_helper.php”, then copy below given code and paste it in helper file

Helper: application/helpers/pdf_helper.php

function tcpdf()
{
    require_once('tcpdf/config/lang/eng.php');
    require_once('tcpdf/tcpdf.php');
}

Then in controller file call the above helper, suppose our controller file is “createpdf.php” and it has method as pdf(), so the method pdf() will load the “pdf_helper” helper and will also have any other code.

Controller: application/controllers/createpdf.php

function pdf()
{
    $this->load->helper('pdf_helper');
    /*
        ---- ---- ---- ----
        your code here
        ---- ---- ---- ----
    */
    $this->load->view('pdfreport', $data);
}

Now create one view file, say “pdfreport.php” in “application/views/” directory, which is also loaded in pdf() method in controller. So in view file we can directly call the tcpdf() function which we have defined in “pdf_helper” helper, which will load all required TCPDF classes, functions, variable etc. Then we can directly use the TCPDF example codes as it is in our current controller or view. Now in out current view “pdfreport” copy the given code below:

View: application/views/pdfreport.php

tcpdf();
$obj_pdf = new TCPDF('P', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->SetCreator(PDF_CREATOR);
$title = "PDF Report";
$obj_pdf->SetTitle($title);
$obj_pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $title, PDF_HEADER_STRING);
$obj_pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$obj_pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$obj_pdf->SetDefaultMonospacedFont('helvetica');
$obj_pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$obj_pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$obj_pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$obj_pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$obj_pdf->SetFont('helvetica', '', 9);
$obj_pdf->setFontSubsetting(false);
$obj_pdf->AddPage();
ob_start();
    // we can have any view part here like HTML, PHP etc
    $content = ob_get_contents();
ob_end_clean();
$obj_pdf->writeHTML($content, true, false, true, false, '');
$obj_pdf->Output('output.pdf', 'I');

Thus our HTML page will be converted to PDF using TCPDF in CodeIgniter. We can also embed images,css,modifications in PDF file by using TCPDF library.

If your key has a fixed number of digits, you should probably store as text rather than as numeric data. You can use the converters argument or read_excel for this.

Or, if this does not work, just manipulate your data once it's read into your dataframe:

df['key_zfill'] = df['key'].astype(str).str.zfill(4)

  names   key key_zfill
0   abc     5      0005
1   def  4962      4962
2   ghi   300      0300
3   jkl    14      0014
4   mno    20      0020

Actually I found out that the container of the image tag need to have a height in order to keep the ratio of the image. for example>

.container{display:flex; height:100%;} img{width:100%;height:auto;}

then in your html your container will wrap the tag image

<div class="container"><img src="image.jpg" alt="image" /></div>

this work for IE and other browsers

You can dectect all Internet Explorer (Last Version Tested 12).

<script>
    var $userAgent = '';
    if(/MSIE/i['test'](navigator['userAgent'])==true||/rv/i['test'](navigator['userAgent'])==true||/Edge/i['test'](navigator['userAgent'])==true){
       $userAgent='ie';
    } else {
       $userAgent='other';
    }

    alert($userAgent);
</script>

See here https://jsfiddle.net/v7npeLwe/

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

Forget using plt.title and place the text directly with plt.text. An over-exaggerated example is given below:

import pylab as plt

fig = plt.figure(figsize=(5,10))

figure_title = "Normal title"
ax1  = plt.subplot(1,2,1)

plt.title(figure_title, fontsize = 20)
plt.plot([1,2,3],[1,4,9])

figure_title = "Raised title"
ax2  = plt.subplot(1,2,2)

plt.text(0.5, 1.08, figure_title,
         horizontalalignment='center',
         fontsize=20,
         transform = ax2.transAxes)
plt.plot([1,2,3],[1,4,9])

plt.show()

[[[UIDevice currentDevice] systemVersion] floatValue]

 textBlock.Foreground = new SolidColorBrush(Colors.White);

For me, it was the ZendDebugger that caused the memory leak and cuased the MemoryManager to crash.

I disabled it and I'm currently searching for a newer version. If I can't find one, I'm going to switch to xdebug...

Since globals are module specific, you can add the following function to all imported modules, and then use it to:

• Add singular variables (in dictionary format) as globals for those
• Transfer your main module globals to it .

addglobals = lambda x: globals().update(x)

Then all you need to pass on current globals is:

import module

module.addglobals(globals())

I've found an solution. I use an solution of Steve Gentile, jQuery and ASP.NET MVC – sending JSON to an Action – Revisited.

My ASP.NET MVC view code looks like:

function getplaceholders() {
        var placeholders = $('.ui-sortable');
        var results = new Array();
        placeholders.each(function() {
            var ph = $(this).attr('id');
            var sections = $(this).find('.sort');
            var section;

            sections.each(function(i, item) {
                var sid = $(item).attr('id');
                var o = { 'SectionId': sid, 'Placeholder': ph, 'Position': i };
                results.push(o);
            });
        });
        var postData = { widgets: results };
        var widgets = results;
        $.ajax({
            url: '/portal/Designer.mvc/SaveOrUpdate',
            type: 'POST',
            dataType: 'json',
            data: $.toJSON(widgets),
            contentType: 'application/json; charset=utf-8',
            success: function(result) {
                alert(result.Result);
            }
        });
    };

and my controller action is decorated with an custom attribute

[JsonFilter(Param = "widgets", JsonDataType = typeof(List<PageDesignWidget>))]
public JsonResult SaveOrUpdate(List<PageDesignWidget> widgets

Code for the custom attribute can be found here (the link is broken now).

Because the link is broken this is the code for the JsonFilterAttribute

public class JsonFilter : ActionFilterAttribute
{
    public string Param { get; set; }
    public Type JsonDataType { get; set; }
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (filterContext.HttpContext.Request.ContentType.Contains("application/json"))
        {
            string inputContent;
            using (var sr = new StreamReader(filterContext.HttpContext.Request.InputStream))
            {
                inputContent = sr.ReadToEnd();
            }
            var result = JsonConvert.DeserializeObject(inputContent, JsonDataType);
            filterContext.ActionParameters[Param] = result;
        }
    }
}

JsonConvert.DeserializeObject is from Json.NET

Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.

Sometimes using image = array(img).reshape(a,b,c,d) will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is

np.expand_dims(img, axis=0)

It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.

This Worked for me ! For Angular 2 , Call child component method in parent component

Parent.component.ts

    import { Component, OnInit, ViewChild } from '@angular/core';
    import { ChildComponent } from '../child/child'; 
    @Component({ 
               selector: 'parent-app', 
               template: `<child-cmp></child-cmp>` 
              }) 
    export class parentComponent implements OnInit{ 
        @ViewChild(ChildComponent ) child: ChildComponent ; 

        ngOnInit() { 
           this.child.ChildTestCmp(); } 
}

Child.component.ts

import { Component } from '@angular/core';
@Component({ 
  selector: 'child-cmp', 
  template: `<h2> Show Child Component</h2><br/><p> {{test }}</p> ` 
})
export class ChildComponent {
  test: string;
  ChildTestCmp() 
  { 
    this.test = "I am child component!"; 
  }
 }

Another solution but without using ng-click which still works even for other tags than <a>:

<tr [routerLink]="['/about']">

This way you can also pass parameters to your route: https://stackoverflow.com/a/40045556/838494

(This is my first day with angular. Gentle feedback is welcome)

Be wary of this:

//setup 
window.onresize = function(event) {
    window_resize(event);

import pyclbr
print(pyclbr.readmodule(__name__).keys())

Note that the stdlib's Python class browser module uses static source analysis, so it only works for modules that are backed by a real .py file.

A simple solution that works well, is to parse the double from the string representation of the float:

double val = Double.valueOf(String.valueOf(yourFloat));

Not super efficient, but it works!

All your elements should have a unique IDs, so there should not be more than one element with #myid

An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).

Neverthless, try this:

$("span[id=myid]").remove();

There are a several ways of declaring variables in SQL*Plus scripts.

The first is to use VAR, to declare a bind variable. The mechanism for assigning values to a VAR is with an EXEC call:

SQL> var name varchar2(20)
SQL> exec :name := 'SALES'

PL/SQL procedure successfully completed.

SQL> select * from dept
  2  where dname = :name
  3  /

    DEPTNO DNAME          LOC
---------- -------------- -------------
        30 SALES          CHICAGO

SQL>

A VAR is particularly useful when we want to call a stored procedure which has OUT parameters or a function.

Alternatively we can use substitution variables. These are good for interactive mode:

SQL> accept p_dno prompt "Please enter Department number: " default 10
Please enter Department number: 20
SQL> select ename, sal
  2  from emp
  3  where deptno = &p_dno
  4  /
old   3: where deptno = &p_dno
new   3: where deptno = 20

ENAME             SAL
---------- ----------
CLARKE            800
ROBERTSON        2975
RIGBY            3000
KULASH           1100
GASPAROTTO       3000

SQL>

When we're writing a script which calls other scripts it can be useful to DEFine the variables upfront. This snippet runs without prompting me to enter a value:

SQL> def p_dno = 40
SQL> select ename, sal
  2  from emp
  3  where deptno = &p_dno
  4  /
old   3: where deptno = &p_dno
new   3: where deptno = 40

no rows selected

SQL>

Finally there's the anonymous PL/SQL block. As you see, we can still assign values to declared variables interactively:

SQL> set serveroutput on size unlimited
SQL> declare
  2      n pls_integer;
  3      l_sal number := 3500;
  4      l_dno number := &dno;
  5  begin
  6      select count(*)
  7      into n
  8      from emp
  9      where sal > l_sal
 10      and deptno = l_dno;
 11      dbms_output.put_line('top earners = '||to_char(n));
 12  end;
 13  /
Enter value for dno: 10
old   4:     l_dno number := &dno;
new   4:     l_dno number := 10;
top earners = 1

PL/SQL procedure successfully completed.

SQL>

As this is only tagged sql (which does not indicate any specific DBMS), here is a solution for Postgres:

select d::date 
from generate_series(date '1990-01-01', date '1990-01-01' + interval '100' year, interval '1' day) as t(d);

If you need that a lot, it's more efficient to store that in an table (which can e.g. be indexed):

create table calendar 
as
select d::date as the_date
from generate_series(date '1990-01-01', date '1990-01-01' + interval '100' year, interval '1' day) as t(d);

it also available on repository mavenCentral() ...

dependencies {
    // https://mvnrepository.com/artifact/com.android.volley/volley
    api "com.android.volley:volley:1.1.0'
}

You can also use:

@Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\"></script>", "~/bundles/mybundle")

To specify the format of your output in a scenario where you need to use Charset, Type, etc.

Just summarising @libing's answer with a sample that worked for me.

val gson = Gson()
val todoItem: TodoItem = gson.fromJson(this.assets.readAssetsFile("versus.json"), TodoItem::class.java)

private fun AssetManager.readAssetsFile(fileName : String): String = open(fileName).bufferedReader().use{it.readText()}

Without this extension function the same can be achieved by using BufferedReader and InputStreamReader this way:

val i: InputStream = this.assets.open("versus.json")
val br = BufferedReader(InputStreamReader(i))
val todoItem: TodoItem = gson.fromJson(br, TodoItem::class.java)

I had modified my answer tons of times and realized i don't have to say anything, python had explained itself already.

a = 'string'
a.replace('t', '_')
print(a)
>>> 'string'

a = a.replace('t', '_')
print(a)
>>> 's_ring'

b = 100
b + 1
print(b)
>>> 100

b = b + 1
print(b)
>>> 101

def test_id(arg):
    c = id(arg)
    arg = 123
    d = id(arg)
    return

a = 'test ids'
b = id(a)
test_id(a)
e = id(a)

# b = c  = e != d

# this function do change original value
del change_like_mutable(arg):
    arg.append(1)
    arg.insert(0, 9)
    arg.remove(2)
    return

test_1 = [1, 2, 3]
change_like_mutable(test_1)



# this function doesn't 
def wont_change_like_str(arg):
     arg = [1, 2, 3]
     return


test_2 = [1, 1, 1]
wont_change_like_str(test_2)
print("Doesn't change like a imutable", test_2)

This devil is not the reference / value / mutable or not / instance, name space or variable / list or str, IT IS THE SYNTAX, EQUAL SIGN.

I don't think you can at present: see this article on the Postgresql wiki.

The three workarounds from this article are:

1. Recreate the table
2. Add columns and move data
3. Hide the differences with a view.

You must specify :

Response.AppendHeader("content-disposition", "inline; filename=file.pdf");
return new FileStreamResult(stream, "application/pdf")

For the file to be opened directly in the browser instead of being downloaded

Have you tried: http://flori.github.com/json/?

Failing that, you could just parse it out? If it's only arrays you're interested in, something to split the above out will be quite simple.

The clean way is to write your own directive to bind to "change" event. Just to let you know IE9 does not support FormData so you cannot really get the file object from the change event.

You can use ng-file-upload library which already supports IE with FileAPI polyfill and simplify the posting the file to the server. It uses a directive to achieve this.

<script src="angular.min.js"></script>
<script src="ng-file-upload.js"></script>

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directive.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', 'Upload', function($scope, Upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var $file = $files[i];
      Upload.upload({
        url: 'my/upload/url',
        data: {file: $file}
      }).then(function(data, status, headers, config) {
        // file is uploaded successfully
        console.log(data);
      }); 
    }
  }
}];

I was looking for an solution to make an XHR request to a server from a local html file and found a solution using Chrome and PHP. (no Jquery)

Javascripts:

var x = new XMLHttpRequest(); 
if(x) x.onreadystatechange=function(){ 
    if (x.readyState === 4 && x.status===200){
        console.log(x.responseText); //Success
    }else{ 
        console.log(x); //Failed
    }
};
x.open(GET, 'http://example.com/', true);
x.withCredentials = true;
x.send();

My Chrome's request header Origin: null

My PHP response header (Note that 'null' is a string). HTTP_REFERER allow cross-origin from a remote server to another.

header('Access-Control-Allow-Origin: '.(trim($_SERVER['HTTP_REFERER'],'/')?:'null'),true);
header('Access-Control-Allow-Credentials:true',true);

I was able to successfully connect to my server. You can disregards the Credentials headers, but this works for me with Apache's AuthType Basic enabled

I tested compatibility with FF and Opera, It works in many cases such as:

From a VM LAN IP (192.168.0.x) back to the VM'S WAN (public) IP:port
From a VM LAN IP back to a remote server domain name.
From a local .HTML file to the VM LAN IP and/or VM WAN IP:port,
From a local .HTML file to a remote server domain name.
And so on.

If any of your .env variables contains white space, make sure you wrap them in double-quotes. For example:

SITE_NAME="My website"

Don't forget to clear your cache before testing:

php artisan config:cache
php artisan config:clear

using C# 6.0

$"Date-{DateTime.Now:yyyyMMddHHmmss}"
