=if(a1="","1","0")

In this formula if the cell is empty then the result would be 1 else it would be 0

If you need to have the script keep working on python2 and 3 as I did, this might help someone

import sys
if sys.version_info[0] >= 3:
    unicode = str

and can then just do for example

foo = unicode.lower(foo)

sysname is used by sp_send_dbmail, a stored procedure that "Sends an e-mail message to the specified recipients" and located in the msdb database.

According to Microsoft,

[ @profile_name = ] 'profile_name'  

Is the name of the profile to send the message from. The profile_name is of type sysname, with a default of NULL. The profile_name must be the name of an existing Database Mail profile. When no profile_name is specified, sp_send_dbmail uses the default private profile for the current user. If the user does not have a default private profile, sp_send_dbmail uses the default public profile for the msdb database. If the user does not have a default private profile and there is no default public profile for the database, @profile_name must be specified.

If you are getting this error on GitLab CI like me: Just change from latest to 5.7 version ;)

# .gitlab-ci.yml

rspec:
  services:
    # - mysql:latest (I'm using latest version and it causes error)
    - mysql:5.7 #(then I've changed to this specific version and fix!)

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

Easy code, if 'indexOf' returns '-1' it means that element is not inside the array then the condition '=== -1' retrieve true/false.

The '&&' operator means 'and', so if the first condition is true we push it to the array.

array.indexOf(newItem) === -1 && array.push(newItem);

In interface Builder set table view separator "None"

and those separator lines which are shown after the last cell can be remove by following approach. Best approach is to assign Empty View to tableView FooterView in viewDidLoad

self.tableView.tableFooterView = UIView()

student_user = User.objects.get(id=user_id)
available_subjects = Subject.objects.exclude(subject_grade__student__user=student_user) # My ans
enrolled_subjects = SubjectGrade.objects.filter(student__user=student_user)
context.update({'available_subjects': available_subjects, 'student_user': student_user, 
                'request':request, 'enrolled_subjects': enrolled_subjects})

In my application above, i assume that once a student is enrolled, a subject SubjectGrade instance will be created that contains the subject enrolled and the student himself/herself.

Subject and Student User model is a Foreign Key to the SubjectGrade Model.

In "available_subjects", i excluded all the subjects that are already enrolled by the current student_user by checking all subjectgrade instance that has "student" attribute as the current student_user

PS. Apologies in Advance if you can't still understand because of my explanation. This is the best explanation i Can Provide. Thank you so much

I found an alternative that works.

None of these answers worked for me (currently testing in FireFox 22.0), and after a lot of research I found, what seems to be, a much cleaner and straight forward solution.

Implemented solution:

function IsScrollbarAtBottom() {
    var documentHeight = $(document).height();
    var scrollDifference = $(window).height() + $(window).scrollTop();
    return (documentHeight == scrollDifference);
}

As per node js doc process.cwd()

cwd is a method of global object process, returns a string value which is the current working directory of the Node.js process.

As per node js doc __dirname

The directory name of current script as a string value. __dirname is not actually a global but rather local to each module.

Let me explain with example,

suppose we have a main.js file resides inside C:/Project/main.js and running node main.js both these values return same file

or simply with following folder structure

Project 
+-- main.js
+--lib
   +-- script.js

main.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

suppose we have another file script.js files inside a sub directory of project ie C:/Project/lib/script.js and running node main.js which require script.js

main.js

require('./lib/script.js')
console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

script.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project\lib
console.log(__dirname===process.cwd())
// false

 $(document).on('change', '.check-all', function () {
   if($(this).prop('checked')) {
      $('.check-box').prop('checked', true)
   }else {
      $('.check-box').prop('checked', false);
   }

Step To Use AutoMapper with ASP.NET Core.

Step 1. Installing AutoMapper.Extensions.Microsoft.DependencyInjection from NuGet Package.

Step 2. Create a Folder in Solution to keep Mappings with Name "Mappings".

Step 3. After adding Mapping folder we have added a class with Name "MappingProfile" this name can anything unique and good to understand.

In this class, we are going to Maintain all Mappings.

Step 4. Initializing Mapper in Startup "ConfigureServices"

In Startup Class, we Need to Initialize Profile which we have created and also Register AutoMapper Service.

  Mapper.Initialize(cfg => cfg.AddProfile<MappingProfile>());

  services.AddAutoMapper();

Code Snippet to show ConfigureServices Method where we need to Initialize and Register AutoMapper.

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }


    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });


        // Start Registering and Initializing AutoMapper

        Mapper.Initialize(cfg => cfg.AddProfile<MappingProfile>());
        services.AddAutoMapper();

        // End Registering and Initializing AutoMapper

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

    }}

Step 5. Get Output.

To Get Mapped result we need to call AutoMapper.Mapper.Map and pass Proper Destination and Source.

AutoMapper.Mapper.Map<Destination>(source);

CodeSnippet

    [HttpPost]
    public void Post([FromBody] SchemeMasterViewModel schemeMaster)
    {
        if (ModelState.IsValid)
        {
            var mappedresult = AutoMapper.Mapper.Map<SchemeMaster>(schemeMaster);
        }
    }

Just put it between center tags:

<center>><Your text here>></center>

provided I understood correctly, you should look for binascii.unhexlify

import binascii
a='45222e'
s=binascii.unhexlify(a)
b=[ord(x) for x in s]

you could also specify multiple style values like this

$('#navigation ul li').css({'display': 'inline-block','background-color': '#ff0000', 'color': '#ffffff'});

I'm using json lib from http://json-lib.sourceforge.net/
json-lib-2.1-jdk15.jar

import net.sf.json.JSONObject;
...

public void send()
{
    //put attributes
    Map m = New HashMap();
    m.put("send_to","[email protected]");
    m.put("email_subject","this is a test email");
    m.put("email_content","test email content");

    //generate JSON Object
    JSONObject json = JSONObject.fromObject(content);
    String message = json.toString();
    ...
}

public void receive(String jsonMessage)
{
    //parse attributes
    JSONObject json = JSONObject.fromObject(jsonMessage);
    String to = (String) json.get("send_to");
    String title = (String) json.get("email_subject");
    String content = (String) json.get("email_content");
    ...
}

I installed HandyCache, in them install link on my general proxy.

In IE set proxy 127.0.0.1.

In Eclipse, Window > Preferences > General > Network Connections, set Active Provider = Native.

Do you want to do it automatically or manually? If manually, a JAR file is really just a ZIP file, so you should be able to open it with any ZIP reader. (You may need to change the extension first.) If you want to update the JAR file automatically via Eclipse, you may want to look into Ant support in Eclipse and look at the zip task.

I got similar issue. The mistake i made was I did not add service in the providers array in app.module.ts. Hope this helps, Thank You.

You almost have it, you just left out 0 and forgot the quantifier.

word.matches("^[0-9,;]+$")

For anyone else stuck with this, it's probably not working because the ajax call is interpreting your returned data as text - i.e. it's not yet a JSON object.

You can convert it to a JSON object by manually using the parseJSON command or simply adding the dataType: 'json' property to your ajax call. e.g.

jQuery.ajax({
    type: 'POST',
    url: '<?php echo admin_url('admin-ajax.php'); ?>',
    data: data, 
    dataType: 'json', // ** ensure you add this line **
    success: function(data) {
        jQuery.each(data, function(index, item) {
            //now you can access properties using dot notation
        });
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert("some error");
    }
});

Using Flexbox in my solution I've used the justify-content property for the parent element (container) and I've specified the margins inside the flex-basis property of the items. Check the code snippet below:

.container {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
  justify-content: space-around;_x000D_
  margin-bottom: 10px;_x000D_
}_x000D_
_x000D_
.item {_x000D_
  height: 50px;_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  background-color: #999;_x000D_
}_x000D_
_x000D_
.item-1-4 {_x000D_
  flex-basis: calc(25% - 10px);_x000D_
}_x000D_
_x000D_
.item-1-3 {_x000D_
  flex-basis: calc(33.33333% - 10px);_x000D_
}_x000D_
_x000D_
.item-1-2 {_x000D_
  flex-basis: calc(50% - 10px);_x000D_
}

<div class="container">_x000D_
  <div class="item item-1-4">1</div>_x000D_
  <div class="item item-1-4">2</div>_x000D_
  <div class="item item-1-4">3</div>_x000D_
  <div class="item item-1-4">4</div>_x000D_
</div>_x000D_
<div class="container">_x000D_
  <div class="item item-1-3">1</div>_x000D_
  <div class="item item-1-3">2</div>_x000D_
  <div class="item item-1-3">3</div>_x000D_
</div>_x000D_
<div class="container">_x000D_
  <div class="item item-1-2">1</div>_x000D_
  <div class="item item-1-2">2</div>_x000D_
</div>

Or you could use the "correct" method, similar to your original atoi approach, but with std::stringstream instead. That should work with chars as input as well as strings. (boost::lexical_cast is another option for a more convenient syntax)

(atoi is an old C function, and it's generally recommended to use the more flexible and typesafe C++ equivalents where possible. std::stringstream covers conversion to and from strings)

select method > right click > References > Workspace/Project (your preferred context ) 

or

(Ctrl+Shift+G) 

This will show you a Search view containing the hierarchy of class and method which using this method.

This can become kind of a serious issue if you're using a JS framework with hashbang (/#!/) URLs, e.g. Angular. Indeed, Angular will consider URLs with a non-hashbang fragment as invalid and throw an error :

Error: Invalid url "http://example.com/#_=_", missing hash prefix "#!".

If you're in such a case (and redirecting to your domain root), instead of doing :

window.location.hash = ''; // goes to /#, which is no better

Simply do :

window.location.hash = '!'; // goes to /#!, which allows Angular to take care of the rest

If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}" should do the trick.

String.prototype.padZero= function(len, c){
    var s= this, c= c || '0';
    while(s.length< len) s= c+ s;
    return s;
}

dispite the name, you can left-pad with any character, including a space. I never had a use for right side padding, but that would be easy enough.

The integer passed to the constructor represents its initial capacity, i.e., the number of elements it can hold before it needs to resize its internal array (and has nothing to do with the initial number of elements in the list).

To initialize an list with 60 zeros you do:

List<Integer> list = new ArrayList<Integer>(Collections.nCopies(60, 0));

If you want to create a list with 60 different objects, you could use the Stream API with a Supplier as follows:

List<Person> persons = Stream.generate(Person::new)
                             .limit(60)
                             .collect(Collectors.toList());

To address specific scenario in question:

@Test
public void Test1() {

}

@Test (dependsOnMethods={"Test1"})
public void Test2() {

}

@Test (dependsOnMethods={"Test2"})
public void Test3() {

}

Example from the numpy documentation:

>>> a = numpy.array([[ 0,  1,  2,  3],
               [ 4,  5,  6,  7],
               [ 8,  9, 10, 11],
               [12, 13, 14, 15]])

>>> numpy.delete(a, numpy.s_[1:3], axis=0)                       # remove rows 1 and 2

array([[ 0,  1,  2,  3],
       [12, 13, 14, 15]])

>>> numpy.delete(a, numpy.s_[1:3], axis=1)                       # remove columns 1 and 2

array([[ 0,  3],
       [ 4,  7],
       [ 8, 11],
       [12, 15]])

Type safety is not just a compile time constraint, but a run time constraint. I feel even after all this time, we can add further clarity to this.

There are 2 main issues related to type safety. Memory** and data type (with its corresponding operations).

Memory**

A char typically requires 1 byte per character, or 8 bits (depends on language, Java and C# store unicode chars which require 16 bits). An int requires 4 bytes, or 32 bits (usually).

Visually:

char: |-|-|-|-|-|-|-|-|

int : |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-|

A type safe language does not allow an int to be inserted into a char at run-time (this should throw some kind of class cast or out of memory exception). However, in a type unsafe language, you would overwrite existing data in 3 more adjacent bytes of memory.

int >> char:

|-|-|-|-|-|-|-|-| |?|?|?|?|?|?|?|?| |?|?|?|?|?|?|?|?| |?|?|?|?|?|?|?|?|

In the above case, the 3 bytes to the right are overwritten, so any pointers to that memory (say 3 consecutive chars) which expect to get a predictable char value will now have garbage. This causes undefined behavior in your program (or worse, possibly in other programs depending on how the OS allocates memory - very unlikely these days).

** While this first issue is not technically about data type, type safe languages address it inherently and it visually describes the issue to those unaware of how memory allocation "looks".

Data Type

The more subtle and direct type issue is where two data types use the same memory allocation. Take a int vs an unsigned int. Both are 32 bits. (Just as easily could be a char[4] and an int, but the more common issue is uint vs. int).

|-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-|

|-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-| |-|-|-|-|-|-|-|-|

A type unsafe language allows the programmer to reference a properly allocated span of 32 bits, but when the value of a unsigned int is read into the space of an int (or vice versa), we again have undefined behavior. Imagine the problems this could cause in a banking program:

"Dude! I overdrafted $30 and now I have $65,506 left!!"

...'course, banking programs use much larger data types. ;) LOL!

As others have already pointed out, the next issue is computational operations on types. That has already been sufficiently covered.

Speed vs Safety

Most programmers today never need to worry about such things unless they are using something like C or C++. Both of these languages allow programmers to easily violate type safety at run time (direct memory referencing) despite the compilers' best efforts to minimize the risk. HOWEVER, this is not all bad.

One reason these languages are so computationally fast is they are not burdened by verifying type compatibility during run time operations like, for example, Java. They assume the developer is a good rational being who won't add a string and an int together and for that, the developer is rewarded with speed/efficiency.

It is important to clearly differentiate the idea behind using factory or factory method. Both are meant to address mutually exclusive different kind of object creation problems.

Let's be specific about "factory method":

First thing is that, when you are developing library or APIs which in turn will be used for further application development, then factory method is one of the best selections for creation pattern. Reason behind; We know that when to create an object of required functionality(s) but type of object will remain undecided or it will be decided ob dynamic parameters being passed.

Now the point is, approximately same can be achieved by using factory pattern itself but one huge drawback will introduce into the system if factory pattern will be used for above highlighted problem, it is that your logic of crating different objects(sub classes objects) will be specific to some business condition so in future when you need to extend your library's functionality for other platforms(In more technically, you need to add more sub classes of basic interface or abstract class so factory will return those objects also in addition to existing one based on some dynamic parameters) then every time you need to change(extend) the logic of factory class which will be costly operation and not good from design perspective. On the other side, if "factory method" pattern will be used to perform the same thing then you just need to create additional functionality(sub classes) and get it registered dynamically by injection which doesn't require changes in your base code.

interface Deliverable 
{
    /*********/
}

abstract class DefaultProducer 
{

    public void taskToBeDone() 
    {   
        Deliverable deliverable = factoryMethodPattern();
    }
    protected abstract Deliverable factoryMethodPattern();
}

class SpecificDeliverable implements Deliverable 
{
 /***SPECIFIC TASK CAN BE WRITTEN HERE***/
}

class SpecificProducer extends DefaultProducer 
{
    protected Deliverable factoryMethodPattern() 
    {
        return new SpecificDeliverable();
    }
}

public class MasterApplicationProgram 
{
    public static void main(String arg[]) 
    {
        DefaultProducer defaultProducer = new SpecificProducer();
        defaultProducer.taskToBeDone();
    }
}

Say we have two date select fields, field1, and field2. field2 date depends on field1

$('#field2').datepicker();
$('#field1').datepicker({
  onSelect: function(dateText, inst) {
    $('#field2').val("");
    $('#field2').datepicker("option", "minDate", new Date(dateText));
  }
});

One possible simplification would be to subclass AuthorizeAttribute:

public class RolesAttribute : AuthorizeAttribute
{
    public RolesAttribute(params string[] roles)
    {
        Roles = String.Join(",", roles);
    }
}

Usage:

[Roles("members", "admin")]

Semantically it is the same as Jim Schmehil's answer.

Also,

monthly_mean.plot(x=df.index, y='A')

[Update: Although I discovered this trick independently, I’ve since learned that Thierry Koblentz beat me to it. You can find his 2009 article on A List Apart. Credit where credit is due.]

I know this is an old question, but I encountered a similar problem that I did solve only with CSS. Here is my blog post that discusses the solution. Included in the post is a live example. Code is reposted below.

#container {
  display: inline-block;
  position: relative;
  width: 50%;
}

#dummy {
  margin-top: 75%;
  /* 4:3 aspect ratio */
}

#element {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: silver/* show me! */
}

<div id="container">
  <div id="dummy"></div>
  <div id="element">
    some text
  </div>
</div>

SELECT column1 FROM table WHERE column1 not like '%[0-9]%'

Removing the '^' did it for me. I'm looking at a varchar field and when I included the ^ it excluded all of my non-numerics which is exactly what I didn't want. So, by removing ^ I only got non-numeric values back.

I think you can use JSON.stringify:

// after your each loop
JSON.stringify(values);

I am assuming you want to pass the database name as a parameter and not just run:

SELECT  *
FROM    DBName.sys.tables
WHERE   Name LIKE '%XXX%'

If so, you could use dynamic SQL to add the dbname to the query:

DECLARE @DBName NVARCHAR(200) = 'YourDBName',
        @TableName NVARCHAR(200) = 'SomeString';

IF NOT EXISTS (SELECT 1 FROM master.sys.databases WHERE Name = @DBName)
    BEGIN
        PRINT 'DATABASE NOT FOUND';
        RETURN;
    END;

DECLARE @SQL NVARCHAR(MAX) = '  SELECT  Name
                                FROM    ' + QUOTENAME(@DBName) + '.sys.tables
                                WHERE   Name LIKE ''%'' + @Table + ''%''';

EXECUTE SP_EXECUTESQL @SQL, N'@Table NVARCHAR(200)', @TableName;

if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):

count before dedupe:

df.count()

do the de-dupe (convert the column you are de-duping to string type):

from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))

df.drop_duplicates(subset=['colName']).count()

can use a sorted groupby to check to see that duplicates have been removed:

df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)

getdate() 

is the direct equivalent, but you should always use UTC datetimes

getutcdate()

whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions

$('#elementid').css('border-bottom', 'solid 1px red');

If you're serious about handling all of the invalid characters (not just the few "html" ones), and you have access to System.Xml, here's the simplest way to do proper Xml encoding of value data:

string theTextToEscape = "Something \x1d else \x1D <script>alert('123');</script>";
var x = new XmlDocument();
x.LoadXml("<r/>"); // simple, empty root element
x.DocumentElement.InnerText = theTextToEscape; // put in raw string
string escapedText = x.DocumentElement.InnerXml; // Returns:  Something &#x1D; else &#x1D; &lt;script&gt;alert('123');&lt;/script&gt;

// Repeat the last 2 lines to escape additional strings.

It's important to know that XmlConvert.EncodeName() is not appropriate, because that's for entity/tag names, not values. Using that would be like Url-encoding when you needed to Html-encode.

This solution worked for me:

• go to tsconfig.json and add "strictNullChecks":false

It should be pretty obvious from your question that you're actually just asking about the difference between git merge and git rebase.

So let's suppose you're in the common case - you've done some work on your master branch, and you pull from origin's, which also has done some work. After the fetch, things look like this:

- o - o - o - H - A - B - C (master)
               \
                P - Q - R (origin/master)

If you merge at this point (the default behavior of git pull), assuming there aren't any conflicts, you end up with this:

- o - o - o - H - A - B - C - X (master)
               \             /
                P - Q - R --- (origin/master)

If on the other hand you did the appropriate rebase, you'd end up with this:

- o - o - o - H - P - Q - R - A' - B' - C' (master)
                          |
                          (origin/master)

The content of your work tree should end up the same in both cases; you've just created a different history leading up to it. The rebase rewrites your history, making it look as if you had committed on top of origin's new master branch (R), instead of where you originally committed (H). You should never use the rebase approach if someone else has already pulled from your master branch.

Finally, note that you can actually set up git pull for a given branch to use rebase instead of merge by setting the config parameter branch.<name>.rebase to true. You can also do this for a single pull using git pull --rebase.

If there is XML file with 2 different tables then will:

LOAD XML LOCAL INFILE 'table1.xml' INTO TABLE table1 
LOAD XML LOCAL INFILE 'table1.xml' INTO TABLE table2

work

Its not really a way to quit the program, but a way to force people to quit.

UIAlertView *anAlert = [[UIAlertView alloc] initWithTitle:@"Hit Home Button to Exit" message:@"Tell em why they're quiting" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
[anAlert show];

Although this might sounds like an easy issue, but it's actually not!

I've tried many things to achieve what you're trying to do with pure CSS, and all my tries were failure. But.. there's a possible solution if you use javascript or jquery!

Assuming you have this CSS:

#myheader {
    width: 100%;
}
#mybody {
    width: 100%;
}
#myfooter {
    width: 100%;
}

Assuming you have this HTML:

<div id="myheader">HEADER</div>
<div id="mybody">BODY</div>
<div id="myfooter">FOOTER</div>

Try this with jquery:

<script>
    $(document).ready(function() {
        var windowHeight = $(window).height();/* get the browser visible height on screen */
        var headerHeight = $('#myheader').height();/* get the header visible height on screen */
        var bodyHeight = $('#mybody').height();/* get the body visible height on screen */
        var footerHeight = $('#myfooter').height();/* get the footer visible height on screen */
        var newBodyHeight = windowHeight - headerHeight - footerHeight;
        if(newBodyHeight > 0 && newBodyHeight > bodyHeight) {
            $('#mybody').height(newBodyHeight);
        }
    });
</script>

Note: I'm not using absolute positioning in this solution, as it might look ugly in mobile browsers

There are two ways to approach this.

Option 1: Update the Android Manifest If the settings Activity is always called from the same activity, you can make the relationship in the Android Manifest. Android will automagically show the 'back' button in the ActionBar

<activity
    android:name=".SettingsActivity"
    android:label="Setting Activity">
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.example.example.MainActivity" />
</activity>

Option 2: Change a setting for the ActionBar If you don't know which Activity will call the Settings Activity, you can create it like this. First in your activity that extends ActionBarActivity (Make sure your @imports match the level of compatibility you are looking for).

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_settings_test);
    ActionBar actionBar = getSupportActionBar();
    actionBar.setHomeButtonEnabled(true);
    actionBar.setDisplayHomeAsUpEnabled(true);
}

Then, detect the 'back button' press and tell Android to close the currently open Activity.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            // app icon in action bar clicked; goto parent activity.
            this.finish();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

That should do it!

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

The result will be:

To literally change the color, you could incorporate a CSS transition with a -webkit-filter where when something happens you would invoke the -webkit-filter of your choice. For example:

img {
    -webkit-filter:grayscale(0%);
    transition: -webkit-filter .3s linear;
    }
img:hover 
    {
    -webkit-filter:grayscale(75%);
    }

In addition to the examples by DigitalRoss, here's another form that you can use if you prefer $() instead of backticks `

echo abc $(: comment) \
     def $(: comment) \
     xyz

Of course, you can use the colon syntax with backticks as well:

echo abc `: comment` \
     def `: comment` \
     xyz

Additional Notes

The reason $(#comment) doesn't work is because once it sees the #, it treats the rest of the line as comments, including the closing parentheses: comment). So the parentheses is never closed.

Backticks parse differently and will detect the closing backtick even after a #.

The Java Virtual Machine takes two command line arguments which set the initial and maximum heap sizes: -Xms and -Xmx. You can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there.
For example if you want a 512Mb initial and 1024Mb maximum heap size you could use:

under Windows:

SET _JAVA_OPTIONS = -Xms512m -Xmx1024m

under Linux:

export _JAVA_OPTIONS="-Xms512m -Xmx1024m"

It is possible to read the default JVM heap size programmatically by using totalMemory() method of Runtime class. Use following code to read JVM heap size.

public class GetHeapSize {
    public static void main(String[]args){

        //Get the jvm heap size.
        long heapSize = Runtime.getRuntime().totalMemory();

        //Print the jvm heap size.
        System.out.println("Heap Size = " + heapSize);
    }
}

If it's for debugging, just add a css class for hovering (since elements can have more than one class):

a.hovertest:hover
{
text-decoration:underline;
}

<a href="http://example.com" class="foo bar hovertest">blah</a>

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

• Install M2E plugin.
• Right click your project and select Configure -> Convert to Maven project.

• Then a pom.xml file will show up in your project. Double click the pom.xml, select Dependency tab to add the jars your project depends on.

you can use CSharpProvider:

var code = @"
    public class Abc {
       public string Get() { return ""abc""; }
    }
";

var options = new CompilerParameters();
options.GenerateExecutable = false;
options.GenerateInMemory = false;

var provider = new CSharpCodeProvider();
var compile = provider.CompileAssemblyFromSource(options, code);

var type = compile.CompiledAssembly.GetType("Abc");
var abc = Activator.CreateInstance(type);

var method = type.GetMethod("Get");
var result = method.Invoke(abc, null);

Console.WriteLine(result); //output: abc

for OrderedDict() you can access the elements by indexing by getting the tuples of (key,value) pairs as follows or using '.values()'

>>> import collections
>>> d = collections.OrderedDict()
>>> d['foo'] = 'python'
>>> d['bar'] = 'spam'
>>> d.items()
[('foo', 'python'), ('bar', 'spam')]
>>>d.values()
odict_values(['python','spam'])
>>>list(d.values())
['python','spam']

From Wikipedia:

Applications implementing common services often use specifically reserved, well-known port numbers for receiving service requests from client hosts. This process is known as listening and involves the receipt of a request on the well-known port and reestablishing one-to-one server-client communications on another private port, so that other clients may also contact the well-known service port. The well-known ports are defined by convention overseen by the Internet Assigned Numbers Authority (IANA).

So as others mentioned, it's a convention.

We had a similar problem with BIRT reports in that we wanted to report on those days that had no data. Since there were no entries for those dates, the easiest solution for us was to create a simple table that stored all dates and use that to get ranges or join to get zero values for that date.

We have a job that runs every month to ensure that the table is populated 5 years out into the future. The table is created thus:

create table all_dates (
    dt date primary key
);

No doubt there are magical tricky ways to do this with different DBMS' but we always opt for the simplest solution. The storage requirements for the table are minimal and it makes the queries so much simpler and portable. This sort of solution is almost always better from a performance point-of-view since it doesn't require per-row calculations on the data.

The other option (and we've used this before) is to ensure there's an entry in the table for every date. We swept the table periodically and added zero entries for dates and/or times that didn't exist. This may not be an option in your case, it depends on the data stored.

If you really think it's a hassle to keep the all_dates table populated, a stored procedure is the way to go which will return a dataset containing those dates. This will almost certainly be slower since you have to calculate the range every time it's called rather than just pulling pre-calculated data from a table.

But, to be honest, you could populate the table out for 1000 years without any serious data storage problems - 365,000 16-byte (for example) dates plus an index duplicating the date plus 20% overhead for safety, I'd roughly estimate at about 14M [365,000 * 16 * 2 * 1.2 = 14,016,000 bytes]), a minuscule table in the scheme of things.

Apple already includes a DEBUG flag in debug builds, so you don't need to define your own.

You might also want to consider just redefining NSLog to a null operation when not in DEBUG mode, that way your code will be more portable and you can just use regular NSLog statements:

//put this in prefix.pch

#ifndef DEBUG
#undef NSLog
#define NSLog(args, ...)
#endif

In Eclipse, select preferences.

In preferences, look for Java/Editor/Templates.

Here you will see a list of all of them. And you can even add your own.

Have you tried http://www.dpriver.com/pp/sqlformat.htm?

I'd do this one of two ways. Since you're setting your start and end dates in your t-sql code, i wouldn't ask for parameters in the stored proc

Option 1

Create Procedure [Test] AS
    DECLARE @StartDate varchar(10)
    DECLARE @EndDate varchar(10)
    Set @StartDate = '201620' --Define start YearWeek
    Set @EndDate  = (SELECT CAST(DATEPART(YEAR,getdate()) AS varchar(4)) + CAST(DATEPART(WEEK,getdate())-1 AS varchar(2)))

SELECT 
*
FROM
    (SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
    LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)

Option 2

Create Procedure [Test] @StartDate varchar(10),@EndDate varchar(10) AS

SELECT 
*
FROM
    (SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
    LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)

Then run exec test '2016-01-01','2016-01-25'

For Angular 2.0.0-rc.0 adding node_modules/angular2/typings/browser.d.ts won't work. First add typings.json file to your solution, with this content:

{
    "ambientDependencies": {
        "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
    }
}

And then update the package.json file to include this postinstall:

"scripts": {
    "postinstall": "typings install"
},

Now run npm install

Also now you should ignore typings folder in your tsconfig.json file as well:

 "exclude": [
        "node_modules",
        "typings/main",
        "typings/main.d.ts"
    ]

Update

Now AngularJS 2.0 is using core-js instead of es6-shim. Follow its quick start typings.json file for more info.

According to the documentation you need to specify the key store:

Protocol authhttps = new Protocol("https",  
      new AuthSSLProtocolSocketFactory(
          new URL("file:my.keystore"), "mypassword",
          new URL("file:my.truststore"), "mypassword"), 443); 

 HttpClient client = new HttpClient();
 client.getHostConfiguration().setHost("localhost", 443, authhttps);

And there it is... right under my nose:

From the react docs themselves: https://facebook.github.io/react/docs/reusable-components.html

// An array of a certain type
    optionalArrayOf: React.PropTypes.arrayOf(React.PropTypes.number),

You can use the in operator:

if "blah" not in somestring: 
    continue

let image = UIImage(systemName: "envelope")
let textField = UITextField()
textField.leftView = UIImageView(image: image)
textField.leftView?.frame = CGRect(x: 5, y: 5, width: 20 , height:20)
textField.leftViewMode = .always

I know this topic is old but I think my answer can be useful for a lot of people.

Here is jQuery plugin made from Pointy's answer using ES6:

/**
 * Sort values alphabetically in select
 * source: http://stackoverflow.com/questions/12073270/sorting-options-elements-alphabetically-using-jquery
 */
$.fn.extend({
    sortSelect() {
        let options = this.find("option"),
            arr = options.map(function(_, o) { return { t: $(o).text(), v: o.value }; }).get();

        arr.sort((o1, o2) => { // sort select
            let t1 = o1.t.toLowerCase(), 
                t2 = o2.t.toLowerCase();
            return t1 > t2 ? 1 : t1 < t2 ? -1 : 0;
        });

        options.each((i, o) => {
            o.value = arr[i].v;
            $(o).text(arr[i].t);
        });
    }
});

Use is very easy

$("select").sortSelect();

NPM is a package manager, you can install node.js packages using NPM

NPX is a tool to execute node.js packages.

It doesn't matter whether you installed that package globally or locally. NPX will temporarily install it and run it. NPM also can run packages if you configure a package.json file and include it in the script section.

So remember this, if you want to check/run a node package quickly without installing locally or globally use NPX.

npM - Manager

npX - Execute - easy to remember

What is a lambda function?

The C++ concept of a lambda function originates in the lambda calculus and functional programming. A lambda is an unnamed function that is useful (in actual programming, not theory) for short snippets of code that are impossible to reuse and are not worth naming.

In C++ a lambda function is defined like this

[]() { } // barebone lambda

or in all its glory

[]() mutable -> T { } // T is the return type, still lacking throw()

[] is the capture list, () the argument list and {} the function body.

The capture list

The capture list defines what from the outside of the lambda should be available inside the function body and how. It can be either:

1. a value: [x]
2. a reference [&x]
3. any variable currently in scope by reference [&]
4. same as 3, but by value [=]

You can mix any of the above in a comma separated list [x, &y].

The argument list

The argument list is the same as in any other C++ function.

The function body

The code that will be executed when the lambda is actually called.

Return type deduction

If a lambda has only one return statement, the return type can be omitted and has the implicit type of decltype(return_statement).

Mutable

If a lambda is marked mutable (e.g. []() mutable { }) it is allowed to mutate the values that have been captured by value.

Use cases

The library defined by the ISO standard benefits heavily from lambdas and raises the usability several bars as now users don't have to clutter their code with small functors in some accessible scope.

C++14

In C++14 lambdas have been extended by various proposals.

Initialized Lambda Captures

An element of the capture list can now be initialized with =. This allows renaming of variables and to capture by moving. An example taken from the standard:

int x = 4;
auto y = [&r = x, x = x+1]()->int {
            r += 2;
            return x+2;
         }();  // Updates ::x to 6, and initializes y to 7.

and one taken from Wikipedia showing how to capture with std::move:

auto ptr = std::make_unique<int>(10); // See below for std::make_unique
auto lambda = [ptr = std::move(ptr)] {return *ptr;};

Generic Lambdas

Lambdas can now be generic (auto would be equivalent to T here if T were a type template argument somewhere in the surrounding scope):

auto lambda = [](auto x, auto y) {return x + y;};

Improved Return Type Deduction

C++14 allows deduced return types for every function and does not restrict it to functions of the form return expression;. This is also extended to lambdas.

If you would like to work with a textbox, be aware that setting the TextMode property to "Date" will not work on Internet Explorer 11, because it does not currently support the "Date", "DateTime", nor "Time" values.

This example illustrates how to implement it using a textbox, including validation of the dates (since the user could enter just numbers). It will work on Internet Explorer 11 as well other web browsers.

With the perspective of the OS X v10.7 and iOS 5 launches, probably the first thing to recommend now is NSJSONSerialization, Apple's supplied JSON parser. Use third-party options only as a fallback if you find that class unavailable at runtime.

So, for example:

NSData *returnedData = ...JSON data, probably from a web request...

// probably check here that returnedData isn't nil; attempting
// NSJSONSerialization with nil data raises an exception, and who
// knows how your third-party library intends to react?

if(NSClassFromString(@"NSJSONSerialization"))
{
    NSError *error = nil;
    id object = [NSJSONSerialization
                      JSONObjectWithData:returnedData
                      options:0
                      error:&error];

    if(error) { /* JSON was malformed, act appropriately here */ }

    // the originating poster wants to deal with dictionaries;
    // assuming you do too then something like this is the first
    // validation step:
    if([object isKindOfClass:[NSDictionary class]])
    {
        NSDictionary *results = object;
        /* proceed with results as you like; the assignment to
        an explicit NSDictionary * is artificial step to get 
        compile-time checking from here on down (and better autocompletion
        when editing). You could have just made object an NSDictionary *
        in the first place but stylistically you might prefer to keep
        the question of type open until it's confirmed */
    }
    else
    {
        /* there's no guarantee that the outermost object in a JSON
        packet will be a dictionary; if we get here then it wasn't,
        so 'object' shouldn't be treated as an NSDictionary; probably
        you need to report a suitable error condition */
    }
}
else
{
    // the user is using iOS 4; we'll need to use a third-party solution.
    // If you don't intend to support iOS 4 then get rid of this entire
    // conditional and just jump straight to
    // NSError *error = nil;
    // [NSJSONSerialization JSONObjectWithData:...
}

Replace

var result= string.search(/searchstring/i);

with

var result= string.search(new RegExp(searchstring, "i"));

SELECT MAX(col) +1 is not safe -- it does not ensure that you aren't inserting more than one customer with the same customer_id value, regardless if selecting from the same table or any others. The proper way to ensure a unique integer value is assigned on insertion into your table in MySQL is to use AUTO_INCREMENT. The ANSI standard is to use sequences, but MySQL doesn't support them. An AUTO_INCREMENT column can only be defined in the CREATE TABLE statement:

CREATE TABLE `customers` (
  `customer_id` int(11) NOT NULL AUTO_INCREMENT,
  `firstname` varchar(45) DEFAULT NULL,
  `surname` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`customer_id`)
)

That said, this worked fine for me on 5.1.49:

CREATE TABLE `customers` (

You can add an empty value such as:

ddlmonths.Items.Insert(0, new ListItem("Select Month", ""))

And just add a validation to prevent chosing empty option such as asp:RequiredFieldValidator.

Working code in jsfiddle due to some security issue of stackoverflow: http://jsfiddle.net/k2vwqoyp/

Since creating a tag per version is the best practice, you may want to partition your changelog per version. In that case, this command could help you:

git log YOUR_LAST_VERSION_TAG..HEAD --no-merges --format=%B

Addressing cases that some of the other answers don't handle well:

• Responsive: direct execution of keypress handling code; avoids the vagaries of polling or blocking delays
• Optionality: global keypress is opt-in; otherwise the app should exit normally
• Separation of concerns: less invasive listening code; operates independently of normal console app code.

Many of the solutions on this page involve polling Console.KeyAvailable or blocking on Console.ReadKey. While it's true that the .NET Console is not very cooperative here, you can use Task.Run to move towards a more modern Async mode of listening.

The main issue to be aware of is that, by default, your console thread isn't set up for Async operation--meaning that, when you fall out of the bottom of your main function, instead of awaiting Async completions, your AppDoman and process will end. A proper way to address this would be to use Stephen Cleary's AsyncContext to establish full Async support in your single-threaded console program. But for simpler cases, like waiting for a keypress, installing a full trampoline may be overkill.

The example below would be for a console program used in some kind of iterative batch file. In this case, when the program is done with its work, normally it should exit without requiring a keypress, and then we allow an optional key press to prevent the app from exiting. We can pause the cycle to examine things, possibly resuming, or use the pause as a known 'control point' at which to cleanly break out of the batch file.

static void Main(String[] args)
{
    Console.WriteLine("Press any key to prevent exit...");
    var tHold = Task.Run(() => Console.ReadKey(true));

    // ... do your console app activity ...

    if (tHold.IsCompleted)
    {
#if false   // For the 'hold' state, you can simply halt forever...
        Console.WriteLine("Holding.");
        Thread.Sleep(Timeout.Infinite);
#else                            // ...or allow continuing to exit
        while (Console.KeyAvailable)
            Console.ReadKey(true);     // flush/consume any extras
        Console.WriteLine("Holding. Press 'Esc' to exit.");
        while (Console.ReadKey(true).Key != ConsoleKey.Escape)
            ;
#endif
    }
}

This will give you DD MM YYYY YY HH Min Sec variables and works on any Windows machine from XP Pro and later.

set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"

I've recently been struggling with a related issue, discussed at length here: Order of legend entries in ggplot2 barplots with coord_flip() .

As it happens, the reason I had a hard time explaining my issue clearly, involved the relation between (the order of) factors and coord_flip(), as seems to be the case here.

I get the desired result by adding + xlim(rev(levels(x$variable))) to the ggplot statement:

ggplot(x, aes(x=variable,y=value)) + geom_bar() + 
scale_y_continuous("",formatter="percent") + coord_flip() 
+  xlim(rev(levels(x$variable)))

This reverses the order of factors as found in the original data frame in the x-axis, which will become the y-axis with coord_flip(). Notice that in this particular example, the variable also happen to be in alphabetical order, but specifying an arbitrary order of levels within xlim() should work in general.

When working with HTTP it's almost always more useful to refer to HttpURLConnection rather than the base class URLConnection (since URLConnection is an abstract class when you ask for URLConnection.openConnection() on a HTTP URL that's what you'll get back anyway).

Then you can instead of relying on URLConnection#setDoOutput(true) to implicitly set the request method to POST instead do httpURLConnection.setRequestMethod("POST") which some might find more natural (and which also allows you to specify other request methods such as PUT, DELETE, ...).

It also provides useful HTTP constants so you can do:

int responseCode = httpURLConnection.getResponseCode();

if (responseCode == HttpURLConnection.HTTP_OK) {

This demo is returning correctly for me in Chrome 14, FF3 and FF5 (with Firebug):

var mytextvalue = document.getElementById("mytext").value;
console.log(mytextvalue == ''); // true
console.log(mytextvalue == null); // false

and changing the console.log to alert, I still get the desired output in IE6.

5000 lines isn't big (well, depends on how long the lines are...)

Anyway: assuming the string will be a word and will be seperated by whitespace...

lines=open(file_path,'r').readlines()
str_wanted="whatever_youre_looking_for"


    for i in range(len(lines)):
        l1=lines.split()
        for p in range(len(l1)):
            if l1[p]==str_wanted:
                #found
                # i is the file line, lines[i] is the full line, etc.

Check whether its the jpg, png, bmp file that you are providing and write the extension accordingly.

Since HTTP Params class is immutable therefore you need to chain the set method:

const params = new HttpParams()
.set('aaa', '111')
.set('bbb', "222");

Form my point of view, below is my suggestions:

1. Store phone number into a single field as varchar and if you need to split then after retrieve split accordingly.
2. If you store as number then preceding 0 will truncate, so always store as varchar
3. Validate users phone number before inserting into your table.

#!/usr/bin/python2
import sys, subprocess, threading
proc = subprocess.Popen(sys.argv[2:])
timer = threading.Timer(float(sys.argv[1]), proc.terminate)
timer.start()
proc.wait()
timer.cancel()
exit(proc.returncode)

Among the other well-explained answers about memory alignment and structure padding/packing, there is something which I have discovered in the question itself by reading it carefully.

"Why isn't sizeof for a struct equal to the sum of sizeof of each member?"

"Why does the sizeof operator return a size larger for a structure than the total sizes of the structure's members"?

Both questions suggest something what is plain wrong. At least in a generic, non-example focused view, which is the case here.

The result of the sizeof operand applied to a structure object can be equal to the sum of sizeof applied to each member separately. It doesn't have to be larger/different.

If there is no reason for padding, no memory will be padded.

One most implementations, if the structure contains only members of the same type:

struct foo {
   int a;   
   int b;
   int c;     
} bar;

Assuming sizeof(int) == 4, the size of the structure bar will be equal to the sum of the sizes of all members together, sizeof(bar) == 12. No padding done here.

Same goes for example here:

struct foo {
   short int a;   
   short int b;
   int c;     
} bar;

Assuming sizeof(short int) == 2 and sizeof(int) == 4. The sum of allocated bytes for a and b is equal to the allocated bytes for c, the largest member and with that everything is perfectly aligned. Thus, sizeof(bar) == 8.

This is also object of the second most popular question regarding structure padding, here:

• Memory alignment in C-structs

IEnumerable<Book> _Book_IE;
List<Book> _Book_List;

If it's the generic variant:

_Book_IE = _Book_List;

If you want to convert to the non-generic one:

IEnumerable ie = (IEnumerable)_Book_List;

If you use Python from MacPorts, it has it's own easy_install located at: /opt/local/bin/easy_install-2.6 (for py26, that is). It's not the same one as simply calling easy_install directly, even if you used python_select to change your default python command.

You are missing 'json' dataType in the $.post() method:

$.post('http://www.example.com:PORT_NUMBER/MYSERVLET',{MyParam: 'value'})
        .done(function(data){
                  alert(data);
         }, "json");
         //-^^^^^^-------here

Updates:

try with this:

response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));

Python docs has an answer that covers +/-, and exponent notation

scanf() Token      Regular Expression
%e, %E, %f, %g     [-+]?(\d+(\.\d*)?|\.\d+)([eE][-+]?\d+)?
%i                 [-+]?(0[xX][\dA-Fa-f]+|0[0-7]*|\d+)

This regular expression does not support international formats where a comma is used as the separator character between the whole and fractional part (3,14159). In that case, replace all \. with [.,] in the above float regex.

                        Regular Expression
International float     [-+]?(\d+([.,]\d*)?|[.,]\d+)([eE][-+]?\d+)?

There are more than one way to increment a variable in bash, but what you tried is not correct.

You can use for example arithmetic expansion:

i=$((i+1))

or only:

((i=i+1))

or:

((i+=1))

or even:

((i++))

Or you can use let:

let "i=i+1"

or only:

let "i+=1"

or even:

let "i++"

See also: http://tldp.org/LDP/abs/html/dblparens.html.

Or try to check your mainActivity.xml you make sure that this one
xmlns:app="http://schemas.android.com/apk/res-auto"hereis included

$('#_SelectID').change(function () {
        var SelectedText = $('option:selected',this).text();
        var SelectedValue = $('option:selected',this).val();
});

It depends on when the self executing anonymous function is running. It is possible that it is running before window.document is defined.

In that case, try adding a listener

window.addEventListener('load', yourFunction, false);
// ..... or 
window.addEventListener('DOMContentLoaded', yourFunction, false);

yourFunction () {
  // some ocde

}

Update: (after the update of the question and inclusion of the code)

Try to use redoc-cli.

I was using bootprint-openapi by which I was generating a bunch of files (bundle.js, bundle.js.map, index.html, main.css and main.css.map) and then you can convert it into a single .html file using html-inline to generate a simple index.html file.

Then I found redoc-cli very easy to to use and output is really-2 awesome, a single and beautiful index.html file.

Installation:

npm install -g redoc-cli

Usage:

redoc-cli bundle -o index.html swagger.json

that's all you need

childView.frame = parentView.bounds

I just use whatever strikes my fancy at the time; it's convenient to be able to switch between the two at a whim!

Of course, when quoting quote characetrs, switching between the two might not be so whimsical after all...

If you sort the outer array, you can use _.isEqual() since the inner array is already sorted.

var array1 = [['a', 'b'], ['b', 'c']];
var array2 = [['b', 'c'], ['a', 'b']];
_.isEqual(array1.sort(), array2.sort()); //true

Note that .sort() will mutate the arrays. If that's a problem for you, make a copy first using (for example) .slice() or the spread operator (...).

Or, do as Daniel Budick recommends in a comment below:

_.isEqual(_.sortBy(array1), _.sortBy(array2))

Lodash's sortBy() will not mutate the array.

From http://psoug.org/reference/roles.html, create a procedure on your database for your user to do it:

CREATE OR REPLACE PROCEDURE GRANT_SELECT(to_user in varchar2) AS

  CURSOR ut_cur IS SELECT table_name FROM user_tables;

  RetVal  NUMBER;
  sCursor INT;
  sqlstr  VARCHAR2(250);

BEGIN
    FOR ut_rec IN ut_cur
    LOOP
      sqlstr := 'GRANT SELECT ON '|| ut_rec.table_name || ' TO ' || to_user;
      sCursor := dbms_sql.open_cursor;
      dbms_sql.parse(sCursor,sqlstr, dbms_sql.native);
      RetVal := dbms_sql.execute(sCursor);
      dbms_sql.close_cursor(sCursor);

    END LOOP;
END grant_select;

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

IfLoop's answer (and MatToufoutu's comment) work great for standalone variables, but I wanted to provide an answer for anyone trying to do something similar for individual entries in lists, tuples, or dictionaries.

Dictionaries

existing_dict = {"spam": 1, "eggs": 2}
existing_dict["foo"] = existing_dict["foo"] if "foo" in existing_dict else 3

Returns {"spam": 1, "eggs": 2, "foo": 3}

Lists

existing_list = ["spam","eggs"]
existing_list = existing_list if len(existing_list)==3 else 
                existing_list + ["foo"]

Returns ["spam", "eggs", "foo"]

Tuples

existing_tuple = ("spam","eggs")
existing_tuple = existing_tuple if len(existing_tuple)==3 else 
                 existing_tuple + ("foo",)

Returns ("spam", "eggs", "foo")

(Don't forget the comma in ("foo",) to define a "single" tuple.)

The lists and tuples solution will be more complicated if you want to do more than just check for length and append to the end. Nonetheless, this gives a flavor of what you can do.

Understanding how to access multi-indexed pandas DataFrame can help you with all kinds of task like that.

Copy paste this in your code to generate example:

# hierarchical indices and columns
index = pd.MultiIndex.from_product([[2013, 2014], [1, 2]],
                                   names=['year', 'visit'])
columns = pd.MultiIndex.from_product([['Bob', 'Guido', 'Sue'], ['HR', 'Temp']],
                                     names=['subject', 'type'])

# mock some data
data = np.round(np.random.randn(4, 6), 1)
data[:, ::2] *= 10
data += 37

# create the DataFrame
health_data = pd.DataFrame(data, index=index, columns=columns)
health_data

Will give you table like this:

You can make the entire DIV function as a link by adding an onclick="window.location='TARGET URL'" and by setting its style to "cursor:pointer". But it's often a bad idea to do this because search engines won't be able to follow the resulting link, readers won't be able to open in tabs or copy the link location, etc. Instead, you can create a regular anchor tag and then set its style to display:block , and then style this as you would a DIV.

This is an old question, but this may help Mac users.

If you are copying files from Time Machine manually, instead of restoring them through Time Machine, it'll add ACLs to everything, which can mess up your permissions.

For example, the section in this article that says "How to Fix Mac OS X File Permissions" shows that "everyone" has custom permissions, which messes it all up:

You need to remove the ACLs from those directories/files. This Super User answer goes into it, but here's the command:

sudo chmod -RN .

Then you can make sure your directories and files have the proper permissions. I use 750 for directories and 644 for files.

To do this in any ES5-compatible environment

Object.keys(obj).length

(Browser support from here)
(Doc on Object.keys here, includes method you can add to non-ECMA5 browsers)

The solution of driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS) will work on the pages with synch loading. This does not solve, however, the problem on pages loading stuff in async, then the tests will fail all the time if we set the pageLoadTimeOut.

The semantics of C# differs slightly from Java here. In C# assignment in declaration is performed before calling the superclass constructor. In Java it is done immediately after which allows 'this' to be used (particularly useful for anonymous inner classes), and means that the semantics of the two forms really do match.

If you can, make the fields final.

You've correctly diagnosed your problem, so good job. Once you call into your search code, the for loop just keeps right on going.

I'm a big fan of https://github.com/caolan/async, and it serves me well. Basically with it you'd end up with something like:

var async = require('async')
async.eachSeries(Object.keys(config), function (key, next){ 
  search(config[key].query, function(err, result) { // <----- I added an err here
    if (err) return next(err)  // <---- don't keep going if there was an error

    var json = JSON.stringify({
      "result": result
    });
    results[key] = {
      "result": result
    }
    next()    /* <---- critical piece.  This is how the forEach knows to continue to
                       the next loop.  Must be called inside search's callback so that
                       it doesn't loop prematurely.*/
  })
}, function(err) {
  console.log('iterating done');
}); 

I hope that helps!

IMO, you should have a look at the Observer Pattern, and this is how most of the listeners work

What I do for abstract classes and interfaces is the following: I write a test, that uses the object as it is concrete. But the variable of type X (X is the abstract class) is not set in the test. This test-class is not added to the test-suite, but subclasses of it, that have a setup-method that set the variable to a concrete implementation of X. That way I don't duplicate the test-code. The subclasses of the not used test can add more test-methods if needed.

For all those facing a similar issue, I came across this same issue when i was trying to run a particular code snippet, shown below.

<html>
    <head>
        <script>
                var div, container = document.getElementById("container")
                for(var i=0;i<5;i++){
                    div = document.createElement("div");
                    div.onclick = function() { 
                        alert("This is a box #"+i);
                    };
                    container.appendChild(div);
                }
            </script>

    </head>
    <body>
        <div id="container"></div>
    </body>
 </html>

Looking at the error in the console for the above code.

Since the document.getElementById is returning a null and as null does not have a attribute named appendChild, therefore a error is thrown. To solve the issue see the code below.

<html>
    <head>
        <style>
        #container{
            height: 200px;
            width: 700px;
            background-color: red;
            margin: 10px;
        }


        div{
            height: 100px;
            width: 100px;
            background-color: purple;
            margin: 20px;
            display: inline-block;
        }
        </style>
    </head>
    <body>
        <div id="container"></div>
        <script>
                var div, container = document.getElementById("container")
                for(let i=0;i<5;i++){
                    div = document.createElement("div");
                    div.onclick = function() { 
                        alert("This is a box #"+i);
                    };
                    container.appendChild(div);
                }
            </script>
    </body>

I hope this helps. :)

Using Storyboard-

Create-

• Go to main.storyboard (This can be found in theProject Navigator on the left hand side of your Xcode) and drag and drop the "Activity Indicator View" from the Object Library.

• Go to the header file and create an IBOutlet for the UIActivityIndicatorView-

   @interface ViewController : UIViewController
  
       @property (nonatomic,strong) IBOutlet UIActivityIndicatorView *activityIndicatorView;
  
   @end
  

• Establish the connection from the Outlets to the UIActivityIndicatorView.

Start:

Use the following code when you need to start the activity indicator using following code in your implementation file(.m)-

 [self.activityIndicatorView startAnimating];

Stop:

Use the following code when you need to stop the activity indicator using following code in your implementation file(.m)-

 [self.activityIndicatorView stopAnimating];

For checking using a Python shell, do the following.

>>>from django import get_version
>>> get_version()

If you wish to do it in Unix/Linux shell with a single line, then do

python -c 'import django; print(django.get_version())'

Once you have developed an application, then you can check version directly using the following.

python manage.py runserver --version

you can also try with this answer :

 <img src="~/Content/img/@Html.DisplayFor(model =>model.ImagePath)" style="height:200px;width:200px;"/>

In my situation, I needed to retain unique keys with the array values, so I just used a second array:

$arr1 = array("alpha"=>"bravo","charlie"=>"delta","echo"=>"foxtrot");
unset($arr1);

$arr2 = array();
foreach($arr1 as $key=>$value) $arr2[$key] = $value;
$arr1 = $arr2
unset($arr2);

You can also solve this problem via Apache configuration using mod_remoteip, by adding the following to a conf.d file:

RemoteIPHeader X-Forwarded-For
RemoteIPInternalProxy 172.16.0.0/12
LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

I changed my website and app bindings to a new port and it worked for me. This error might occur because the port the website uses is not available. Hence sometimes the problem is solved by simply restarting the machine

-Edit-

Alternative (and easier) solution:reference

1. Get PID of process which is using the port CMD command- netstat -aon | findstr 0.0:80

2. Use the PID to get process name -

tasklist /FI "PID eq "

3. Open task manager, find this process and stop it.

(Note- Make sure you do not stop Net.tcp services)

I have created my own iterator to iterate over Outlook objects via python. The issue is that python tries to iterates starting with Index[0], but outlook expects for first item Index[1]... To make it more Ruby simple, there is below a helper class Oli with following methods:

.items() - yields a tuple(index, Item)...

.prop() - helping to introspect outlook object exposing available properties (methods and attributes)

from win32com.client import constants
from win32com.client.gencache import EnsureDispatch as Dispatch

outlook = Dispatch("Outlook.Application")
mapi = outlook.GetNamespace("MAPI")

class Oli():
    def __init__(self, outlook_object):
        self._obj = outlook_object

    def items(self):
        array_size = self._obj.Count
        for item_index in xrange(1,array_size+1):
            yield (item_index, self._obj[item_index])

    def prop(self):
        return sorted( self._obj._prop_map_get_.keys() )

for inx, folder in Oli(mapi.Folders).items():
    # iterate all Outlook folders (top level)
    print "-"*70
    print folder.Name

    for inx,subfolder in Oli(folder.Folders).items():
        print "(%i)" % inx, subfolder.Name,"=> ", subfolder

I would like to expand open jfs's answer, which worked great for my problem: sorting two lists by a third, decorated list:

We can create our decorated list in any way, but in this case we will create it from the elements of one of the two original lists, that we want to sort:

# say we have the following list and we want to sort both by the algorithms name 
# (if we were to sort by the string_list, it would sort by the numerical 
# value in the strings)
string_list = ["0.123 Algo. XYZ", "0.345 Algo. BCD", "0.987 Algo. ABC"]
dict_list = [{"dict_xyz": "XYZ"}, {"dict_bcd": "BCD"}, {"dict_abc": "ABC"}]

# thus we need to create the decorator list, which we can now use to sort
decorated = [text[6:] for text in string_list]  
# decorated list to sort
>>> decorated
['Algo. XYZ', 'Algo. BCD', 'Algo. ABC']

Now we can apply jfs's solution to sort our two lists by the third

# create and sort the list of indices
sorted_indices = list(range(len(string_list)))
sorted_indices.sort(key=decorated.__getitem__)

# map sorted indices to the two, original lists
sorted_stringList = list(map(string_list.__getitem__, sorted_indices))
sorted_dictList = list(map(dict_list.__getitem__, sorted_indices))

# output
>>> sorted_stringList
['0.987 Algo. ABC', '0.345 Algo. BCD', '0.123 Algo. XYZ']
>>> sorted_dictList
[{'dict_abc': 'ABC'}, {'dict_bcd': 'BCD'}, {'dict_xyz': 'XYZ'}]

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE 0 END AS YOUR_QUERY_ANSWERED

above will return values

however below query wont work

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE **@INPUT_1** END AS YOUR_QUERY_ANSWERED

as @INPUT_1 actually has varchar in it.

So your output column must have a varchar in it.

When you start a thread, it begins executing a function you give it (if you're extending threading.Thread, the function will be run()). To end the thread, just return from that function.

According to this, you can also call thread.exit(), which will throw an exception that will end the thread silently.

Using fgetc(fp) only to be able to call strcpy(buffer,c); doesn't seem right.

You could simply build this buffer on your own:

char buffer[MAX_SIZE_OF_MY_BUFFER];

int i = 0;
char ch;
while (i < MAX_SIZE_OF_MY_BUFFER - 1 && (ch = fgetc(fp)) != EOF) {
    buffer[i++] = ch;
}
buffer[i] = '\0';  // terminating character

Note that this relies on the fact that you will read less than MAX_SIZE_OF_MY_BUFFER characters

Basically, you need to include the Wordpress loop in your search.php template to loop through the search results and show them as part of the template.

Below is a very basic example from The WordPress Theme Search Template and Page Template over at ThemeShaper.

<?php
/**
 * The template for displaying Search Results pages.
 *
 * @package Shape
 * @since Shape 1.0
 */

get_header(); ?>

        <section id="primary" class="content-area">
            <div id="content" class="site-content" role="main">

            <?php if ( have_posts() ) : ?>

                <header class="page-header">
                    <h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'shape' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
                </header><!-- .page-header -->

                <?php shape_content_nav( 'nav-above' ); ?>

                <?php /* Start the Loop */ ?>
                <?php while ( have_posts() ) : the_post(); ?>

                    <?php get_template_part( 'content', 'search' ); ?>

                <?php endwhile; ?>

                <?php shape_content_nav( 'nav-below' ); ?>

            <?php else : ?>

                <?php get_template_part( 'no-results', 'search' ); ?>

            <?php endif; ?>

            </div><!-- #content .site-content -->
        </section><!-- #primary .content-area -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

@robert-hurst has a cleaner approach.

However, this solution may also be used, in places when you actually want to have a copy of Data Url after copying. For example, when you are building a website that uses lots of image/canvas operations.

    // select canvas elements
    var sourceCanvas = document.getElementById("some-unique-id");
    var destCanvas = document.getElementsByClassName("some-class-selector")[0];

    //copy canvas by DataUrl
    var sourceImageData = sourceCanvas.toDataURL("image/png");
    var destCanvasContext = destCanvas.getContext('2d');

    var destinationImage = new Image;
    destinationImage.onload = function(){
      destCanvasContext.drawImage(destinationImage,0,0);
    };
    destinationImage.src = sourceImageData;

If you've copied this directly, then:

->setCellValue('B2', Ackermann') 

should be

->setCellValue('B2', 'Ackermann') 

In answer to your question:

Get the data that you want from limesurvey, and use setCellValue() to store those data values in the cells where you want to store it.

The Quadratic.php example file in /Tests might help as a starting point: it takes data from an input form and sets it to cells in an Excel workbook.

EDIT

An extremely simplistic example:

// Create your database query
$query = "SELECT * FROM myDataTable";  

// Execute the database query
$result = mysql_query($query) or die(mysql_error());

// Instantiate a new PHPExcel object
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number
$rowCount = 1; 
// Iterate through each result from the SQL query in turn
// We fetch each database result row into $row in turn
while($row = mysql_fetch_array($result)){ 
    // Set cell An to the "name" column from the database (assuming you have a column called name)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $row['name']); 
    // Set cell Bn to the "age" column from the database (assuming you have a column called age)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $row['age']); 
    // Increment the Excel row counter
    $rowCount++; 
} 

// Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); 
// Write the Excel file to filename some_excel_file.xlsx in the current directory
$objWriter->save('some_excel_file.xlsx'); 

EDIT #2

Using your existing code as the basis

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel();  
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0);  
// Initialise the Excel row number 
$rowCount = 1;  

//start of printing column names as names of MySQL fields  
$column = 'A';
for ($i = 1; $i < mysql_num_fields($result); $i++)  
{
    $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, mysql_field_name($result,$i));
    $column++;
}
//end of adding column names  

//start while loop to get data  
$rowCount = 2;  
while($row = mysql_fetch_row($result))  
{  
    $column = 'A';
    for($j=1; $j<mysql_num_fields($result);$j++)  
    {  
        if(!isset($row[$j]))  
            $value = NULL;  
        elseif ($row[$j] != "")  
            $value = strip_tags($row[$j]);  
        else  
            $value = "";  

        $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, $value);
        $column++;
    }  
    $rowCount++;
} 


// Redirect output to a client’s web browser (Excel5) 
header('Content-Type: application/vnd.ms-excel'); 
header('Content-Disposition: attachment;filename="Limesurvey_Results.xls"'); 
header('Cache-Control: max-age=0'); 
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); 
$objWriter->save('php://output');

$("element").filter(function() { return $(this).css("display") == "none" });

It's true that true and false don't represent any numerical values in Javascript.

In some languages (e.g. C, VB), the boolean values are defined as actual numerical values, so they are just different names for 1 and 0 (or -1 and 0).

In some other languages (e.g. Pascal, C#), there is a distinct boolean type that is not numerical. It's possible to convert between boolean values and numerical values, but it doesn't happen automatically.

Javascript falls in the category that has a distinct boolean type, but on the other hand Javascript is quite keen to convert values between different data types.

For example, eventhough a number is not a boolean, you can use a numeric value where a boolean value is expected. Using if (1) {...} works just as well as if (true) {...}.

When comparing values, like in your example, there is a difference between the == operator and the === operator. The == equality operator happily converts between types to find a match, so 1 == true evaluates to true because true is converted to 1. The === type equality operator doesn't do type conversions, so 1 === true evaluates to false because the values are of different types.

RFC 2616, section 14.9.1:

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.

Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.

For me, a more concrete example of Cache-Control: private is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.

FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.

This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.

Use subscripting to access the value for a dictionary key. This will return an Optional:

let apple: String? = companies["AAPL"]

or

if let apple = companies["AAPL"] {
    // ...
}

You can also enumerate over all of the keys and values:

var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"]

for (key, value) in companies {
    print("\(key) -> \(value)")
}

Or enumerate over all of the values:

for value in Array(companies.values) {
    print("\(value)")
}

Please check the directory path whether exists or not. This error comes up if the folder doesn't exists from where you are running the command. Probably you have executed a remove command from same path in command line.

At least in Postgres you can use the following statement:

The correct answer:

$window.location.reload(true);

This is a syntax issue, the jQuery library included with WordPress loads in "no conflict" mode. This is to prevent compatibility problems with other javascript libraries that WordPress can load. In "no-confict" mode, the $ shortcut is not available and the longer jQuery is used, i.e.

jQuery(document).ready(function ($) {

By including the $ in parenthesis after the function call you can then use this shortcut within the code block.

For full details see WordPress Codex

If you are planning on doing any kind of inheritance, then I would recommend this.constructor. This simple example should illustrate why:

class ConstructorSuper {
  constructor(n){
    this.n = n;
  }

  static print(n){
    console.log(this.name, n);
  }

  callPrint(){
    this.constructor.print(this.n);
  }
}

class ConstructorSub extends ConstructorSuper {
  constructor(n){
    this.n = n;
  }
}

let test1 = new ConstructorSuper("Hello ConstructorSuper!");
console.log(test1.callPrint());

let test2 = new ConstructorSub("Hello ConstructorSub!");
console.log(test2.callPrint());

• test1.callPrint() will log ConstructorSuper Hello ConstructorSuper! to the console
• test2.callPrint() will log ConstructorSub Hello ConstructorSub! to the console

The named class will not deal with inheritance nicely unless you explicitly redefine every function that makes a reference to the named Class. Here is an example:

class NamedSuper {
  constructor(n){
    this.n = n;
  }

  static print(n){
    console.log(NamedSuper.name, n);
  }

  callPrint(){
    NamedSuper.print(this.n);
  }
}

class NamedSub extends NamedSuper {
  constructor(n){
    this.n = n;
  }
}

let test3 = new NamedSuper("Hello NamedSuper!");
console.log(test3.callPrint());

let test4 = new NamedSub("Hello NamedSub!");
console.log(test4.callPrint());

• test3.callPrint() will log NamedSuper Hello NamedSuper! to the console
• test4.callPrint() will log NamedSuper Hello NamedSub! to the console

See all the above running in Babel REPL.

You can see from this that test4 still thinks it's in the super class; in this example it might not seem like a huge deal, but if you are trying to reference member functions that have been overridden or new member variables, you'll find yourself in trouble.

while

rd /s /q %systemdrive%\$RECYCLE.BIN

will delete the $RECYCLE.BIN folder from the system drive, which is usually c:, one should consider deleting it from any other available partitions since there's an hidden $RECYCLE.BIN folder in any partition in local and external drives (but not in removable drives, like USB flash drive, which don't have a $RECYCLE.BIN folder). For example, I installed a program in d:, in order to delete the files it moved to the Recycle Bin I should run:

rd /s /q d:\$RECYCLE.BIN

Yess, possible with conditions:

If you have your app installed in the user phone and a server app communicating with this app, and there at last one of location service providers activated in the user phone, and some horrible android permissions!

In most of android phones there 3 location providers that can give exact location (GPS_PROVIDER 1m) or estimated (NETWORK_PROVIDER around 2-20m) and PASSIVE_PROVIDER (more in LocationManager official documentation).

1* App sends SMS to user's phone

Yess, can be server app or you create an android app if you want something automated, so you can do it manually by sending SMS from your default SMS app! I use Kannel: Open Source WAP and SMS Gateway and here (lot of APIs to send SMS )

2* App receives SMS at user's phone from the SMS sender

Yess, you can get all received SMS, and you can filter them by sender phone number! and do some actions when your specified sms received, basic tuto here (i do some actions according to the content of my SMS)

3* App gets location coordinates of the user's phone

Yess, you can get actual user coordinates easily if one of location providers is activated, so you can get last known location when the user have activated one of location providers, if those disabled or the phone don't have GPS hardware you can use Open Cell Id api to get the nearest cell coordinates(10m-10Km) or Loc8 api but those not available in all around the world, and some apps use IP location apis to get the country, city and province, here the simplest way to get current user location.

4* App sends location coordinates to the SMS sender via SMS

Yess, you can get sender phone number and send user location, immediately when SMS received or at specified times in the day.

(Those 4 yesses for you :) )

Viber and other apps that access to users locations, identify there users by there phone numbers by obligating them to send SMS to the server app to create an account and activate the free service (Ex:VOIP) , and lunch a service that can:

• Listen for location changes (GPS, Network or Cell Id)
• Send user location periodically(Ex: each 2 hours) or when user position changed!
• Stock user locations in file and create a map based on daily locations
• Receive SMS and update user location
• Receive server app commend and update user location
• Send events when user go inside or outside of a defined circle
• Listen for what user say and record it or open live voip call :s
• Maybe anything you think or u want to do :) !

And your application users must accept all of that when installing it, of corse i don't gonna install apps like this because i read permissions before installing :) and permissions maybe something like that:

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />    
<uses-permission android:name="android.permission.INTERNET" />
<-- and more if you wanna more -->

The final user will accept for something like that (those permissions of an android app u asked about):

This app has access to these permissions:

Your accounts -create accounts and set passwords -find accounts on the device -add or remove accounts -use accounts on the device -read Google service configuration

Your location -approximate location (network-based) -precise location (GPS and network-based)

Your messages -receive text messages (SMS) -send SMS messages -edit your text messages (SMS or MMS) -read your text messages (SMS or MMS)

Network communication -receive data from Internet -full network access -view Wi-Fi connections -view network connections -change network connectivity

Phone calls -read phone status and identity -directly call phone numbers

Storage -modify or delete the contents of your USB storage

Your applications information -retrieve running apps -close other apps -run at startup

Bluetooth -pair with Bluetooth devices -access Bluetooth settings

Camera -take pictures and videos

Other Application UI -draw over other apps

Microphone -record audio

Lock screen -disable your screen lock

Your social information -read your contacts -modify your contacts -read call log -write call log -read your social stream -write to your social stream

Development tools -read sensitive log data

System tools -modify system settings -send sticky broadcast -test access to protected storage

Affects battery -control vibration -prevent device from sleeping

Audio settings -change your audio settings

Sync Settings -read sync settings -toggle sync on and off -read sync statistics

Wallpaper -set wallpaper

 WebElement p= driver.findElement(By.id("your id name"));
 p.sendKeys(Keys.chord(Keys.CONTROL, "a"), "55");

I added the complete code below to display images in Gmail,Thunderbird and other email clients :

MailMessage mailWithImg = getMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!

private MailMessage getMailWithImg()
{
    MailMessage mail = new MailMessage();
    mail.IsBodyHtml = true;
    mail.AlternateViews.Add(getEmbeddedImage("c:/image.png"));
    mail.From = new MailAddress("yourAddress@yourDomain");
    mail.To.Add("recipient@hisDomain");
    mail.Subject = "yourSubject";
    return mail;
}
private AlternateView getEmbeddedImage(String filePath)
 {
    // below line was corrected to include the mediatype so it displays in all 
    // mail clients. previous solution only displays in Gmail the inline images 
    LinkedResource res = new LinkedResource(filePath, MediaTypeNames.Image.Jpeg);  
    res.ContentId = Guid.NewGuid().ToString();
    string htmlBody = @"<img src='cid:" + res.ContentId + @"'/>";
    AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody,  
     null, MediaTypeNames.Text.Html);
    alternateView.LinkedResources.Add(res);
    return alternateView;
}

You can use LINQ for this

var list = new List<int>();
var sum = list.Sum();

and for a List of strings like Roy Dictus said you have to convert

list.Sum(str => Convert.ToInt32(str));

To add to add to the previous answer, there is even a fourth way that can be used

import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

Since there's no Request context in the pipeline during app start anymore, I can't imagine there's any way to guess what server/port the next actual request might come in on. You have to so it on Begin_Session.

Here's what I'm using when not in Classic Mode. The overhead is negligible.

/// <summary>
/// Class is called only on the first request
/// </summary>
private class AppStart
{
    static bool _init = false;
    private static Object _lock = new Object();

    /// <summary>
    /// Does nothing after first request
    /// </summary>
    /// <param name="context"></param>
    public static void Start(HttpContext context)
    {
        if (_init)
        {
            return;
        }
        //create class level lock in case multiple sessions start simultaneously
        lock (_lock)
        {
            if (!_init)
            {
                string server = context.Request.ServerVariables["SERVER_NAME"];
                string port = context.Request.ServerVariables["SERVER_PORT"];
                HttpRuntime.Cache.Insert("basePath", "http://" + server + ":" + port + "/");
                _init = true;
            }
        }
    }
}

protected void Session_Start(object sender, EventArgs e)
{
    //initializes Cache on first request
    AppStart.Start(HttpContext.Current);
}

Also, I add to do the following steps so that the git repo would be correctly linked with the IDE:

 $ git reset <commit #>

 $ git checkout <file/path>

I hope this was helpful!!

When I modify your code to use a file accessed by an absolute path instead of a resource, I get a different result (for 1 run, 1 iteration, and a 100,000 byte file -- times for a 10 byte file are identical to 100,000 bytes)

LENGTH sum: 33, per Iteration: 33.0

CHANNEL sum: 3626, per Iteration: 3626.0

URL sum: 294, per Iteration: 294.0

Simplest solution

If you only call print without any arguments, it will output a blank line.

print

You can pipe the output to a file like this (considering your example):

f = open('out.txt', 'w')
print 'First line' >> f
print >> f
print 'Second line' >> f
f.close()

Not only is it OS-agnostic (without even having to use the os package), it's also more readable than putting \n within strings.

Explanation

The print() function has an optional keyword argument for the end of the string, called end, which defaults to the OS's newline character, for eg. \n. So, when you're calling print('hello'), Python is actually printing 'hello' + '\n'. Which means that when you're calling just print without any arguments, it's actually printing '' + '\n', which results in a newline.

Alternative

Use multi-line strings.

s = """First line
    Second line
    Third line"""
f = open('out.txt', 'w')
print s >> f
f.close()

Use list(str) to break into chars then import string and use string.ascii_uppercase to compare against.

Check the string module: http://docs.python.org/library/string.html

There is little to be added to Garrett's great answer, but pandas also has a scatter method. Using that, it's as easy as

df = pd.DataFrame(np.random.randn(10,2), columns=['col1','col2'])
df['col3'] = np.arange(len(df))**2 * 100 + 100
df.plot.scatter('col1', 'col2', df['col3'])

Mongoose now support timestamps for collections.

Please consider the answer of @bobbyz below. Maybe this is what you are looking for.

Original answer

Mongoose supports a Date type (which is basically a timestamp):

time : { type : Date, default: Date.now }

With the above field definition, any time you save a document with an unset time field, Mongoose will fill in this field with the current time.

Source: http://mongoosejs.com/docs/guide.html

In addition to the above answers, I would say for columns having no single word name, you may use:-

df[df['Product ID'].str.contains("foo") == True]

Hope this helps.

This simple example for multidimensional array with function pointers":

void one( int a, int b){    printf(" \n[ ONE ]  a =  %d   b = %d",a,b);}
void two( int a, int b){    printf(" \n[ TWO ]  a =  %d   b = %d",a,b);}
void three( int a, int b){    printf("\n [ THREE ]  a =  %d   b = %d",a,b);}
void four( int a, int b){    printf(" \n[ FOUR ]  a =  %d   b = %d",a,b);}
void five( int a, int b){    printf(" \n [ FIVE ]  a =  %d   b = %d",a,b);}
void(*p[2][2])(int,int)   ;
int main()
{
    int i,j;
    printf("multidimensional array with function pointers\n");

    p[0][0] = one;    p[0][1] = two;    p[1][0] = three;    p[1][1] = four;
    for (  i  = 1 ; i >=0; i--)
        for (  j  = 0 ; j <2; j++)
            (*p[i][j])( (i, i*j);
    return 0;
}

Just for completeness, here is a recursive version that would allow tail call optimization. I'm not sure if tail call optimizations are performed in JavaScript though..

function rFact(n, acc)
{
    if (n == 0 || n == 1) return acc; 
    else return rFact(n-1, acc*n); 
}

To call it:

rFact(x, 1);

i created a package. it may meet your needs.

Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:

CSS

#container {
    display: table;
    width: 300px; /* not required, just for example */
    height: 400px; /* not required, just for example */
}

#update {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

HTML

<div id="container">
    <a id="update" href="#">
        <i class="icon-refresh"></i>
    </a>
</div>

JSFiddle

Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell display property works.

For-loops:

For-loop in C:

for(int x = 0; x<=3; x++)
{
    //Do something!
}

The same loop in 8086 assembler:

        xor cx,cx   ; cx-register is the counter, set to 0
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        inc cx      ; Increment
        cmp cx,3    ; Compare cx to the limit
        jle loop1   ; Loop while less or equal

That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:

        mov cx,4    ; 4 iterations
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        loop loop1  ; loop instruction decrements cx and jumps to label if not 0

If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction

times 4 nop

Do-while-loops

Do-while-loop in C:

int x=1;
do{
    //Do something!
}
while(x==1)

The same loop in assembler:

        mov ax,1
loop1   nop         ; Whatever you wanna do goes here
        cmp ax,1    ; Check wether cx is 1
        je loop1    ; And loop if equal

While-loops

While-loop in C:

while(x==1){
    //Do something
}

The same loop in assembler:

        jmp loop1   ; Jump to condition first
cloop1  nop         ; Execute the content of the loop
loop1   cmp ax,1    ; Check the condition
        je cloop1   ; Jump to content of the loop if met

For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.

Swift 3

self.paddingView.layer.masksToBounds = false
self.paddingView.layer.shadowOffset = CGSize(width: -15, height: 10)
self.paddingView.layer.shadowRadius = 5
self.paddingView.layer.shadowOpacity = 0.5

You need to change the constructor of the child class to this:

public child(int i) : base(i)
{
    Console.WriteLine("child");
}

The part : base(i) means that the constructor of the base class with one int parameter should be used. If this is missing, you are implicitly telling the compiler to use the default constructor without parameters. Because no such constructor exists in the base class it is giving you this error.

Use System.DateTime.Now.ToUniversalTime(). That puts your reading in a known reference-based millisecond format that totally eliminates day change, etc.

For global setting, open the terminal (from any where) run the following:

  git config --global user.name "your username"
  git config --global user.password "your password"

By that, any local git repo that you have on your machine will use that information.

You can individually config for each repo by doing:

• open terminal at the repo folder.

• run the following:

  git config user.name "your username"
  git config user.password "your password"
  

It affects only that folder (because your configuration is local).

Let's say our parent Dataframe has 'n' columns

we can create 'x' child DataFrames( Lets consider 2 in our case).

The columns for the child Dataframe can be chosen as per desire from any of the parent Dataframe columns.

Consider source has 10 columns and we want to split into 2 DataFrames that contains columns referenced from the parent Dataframe.

The columns for the child Dataframe can be decided using the select Dataframe API

val parentDF = spark.read.format("csv").load("/path of the CSV file")

val Child1_DF = parentDF.select("col1","col2","col3","col9","col10").show()

val child2_DF = parentDF.select("col5", "col6","col7","col8","col1","col2").show()

Notice that the column count in the child dataframes can differ in length and will be less than the parent dataframe column count.

we can also refer to the column names without mentioning the real names using the positional indexes of the desired column from the parent dataframe

Import spark implicits first which acts as a helper class for usage of $-notation to access the columns using the positional indexes

import spark.implicits._
import org.apache.spark.sql.functions._

val child3_DF  = parentDF.select("_c0","_c1","_c2","_c8","_c9").show()

we can also select column basing on certain conditions. Lets say we want only even numbered columns to be selected in the child dataframe. By even we refer to even indexed columns and index being starting from '0'

val parentColumns = parentDF.columns.toList


res0: List[String] = List(_c0, _c1, _c2, _c3, _c4, _c5, _c6, _c7,_c8,_c9)

val evenParentColumns =  res0.zipWithIndex.filter(_._2 % 2 == 0).map( _._1).toSeq

res1: scala.collection.immutable.Seq[String] = List(_c0, _c2, _c4, _c6,_c8)

Now feed these columns to be selected from the parentDF.Note that the select API need seq type arguments.So we converted the "evenParentColumns" to Seq collection

val child4_DF = parentDF.select(res1.head, res1.tail:_*).show()

This will show the even indexed columns from the parent Dataframe.

| _c0 | _c2 | _c4 |_c6 |_c8 |

|ITE00100554|TMAX|null| E| 1 |

|TE00100554 |TMIN|null| E| 4 |

|GM000010962|PRCP|null| E| 7 |

So Now we are left with the even numbered columns in the dataframe

Similarly we can also apply other operations to the Dataframe column like shown below

val child5_DF = parentDF.select($"_c0", $"_c8" + 1).show()

So by many ways as mentioned we can select the columns in the Dataframe.

In addition to the Python 2 approach here are the equivalents for Python 3:

# Create a range that does not contain 50
for i in [x for x in range(100) if x != 50]:
    print(i)

# Create 2 ranges [0,49] and [51, 100]
from itertools import chain
concatenated = chain(range(50), range(51, 100))
for i in concatenated:
    print(i)

# Create a iterator and skip 50
xr = iter(range(100))
for i in xr:
    print(i)
    if i == 49:
        next(xr)

# Simply continue in the loop if the number is 50
for i in range(100):
    if i == 50:
        continue
    print(i)

Ranges are lists in Python 2 and iterators in Python 3.

Here is the implementation that was mentioned above:

    // string as the one above
    String encodedEncrypted = new String(encoded);

    //we recreate the same salt/encrypt as if its a separate system
    String passDecrypt = "my password";
    byte[] saltDecrypt = "choose a better salt".getBytes();
    int iterationsDecrypt = 10000;
    SecretKeyFactory factoryKeyDecrypt = SecretKeyFactory
            .getInstance("PBKDF2WithHmacSHA1");
    SecretKey tmp2 = factoryKeyDecrypt.generateSecret(new PBEKeySpec(passDecrypt
            .toCharArray(), saltDecrypt, iterationsDecrypt, 128));
    SecretKeySpec decryptKey = new SecretKeySpec(tmp2.getEncoded(), "AES");

    Cipher aesCipherDecrypt = Cipher.getInstance("AES/ECB/PKCS5Padding");
            aesCipherDecrypt.init(Cipher.DECRYPT_MODE, decryptKey);

    //basically we reverse the process we did earlier

    // get the bytes from encodedEncrypted string
    byte[] e64bytes = StringUtils.getBytesUtf8(encodedEncrypted);

    // decode 64, now the bytes should be encrypted
    byte[] eBytes = Base64.decodeBase64(e64bytes);

    // decrypt the bytes
    byte[] cipherDecode = aesCipherDecrypt.doFinal(eBytes);

    // to string
    String decoded = StringUtils.newStringUtf8(cipherDecode);

    System.out.println("d: " + decoded);

I had the same problem with numpy arrays and the solution is to flatten them:

data = {
    'b': array1.flatten(),
    'a': array2.flatten(),
}

df = pd.DataFrame(data)

I am using intellij CE to create the WAR, and deploying the war externally using tomcat deployment manager. This works for testing the application however I still couldnt find the way to debug it.

1. open cmd and current dir to tomcat/bin.
2. you can start and stop the server using the batch files start.bat and shutdown.bat.
3. Now build your app using mvn goal in intellij.
4. Open localhost:8080/ **Your port number may differ.
5. Use this tomcat application to deploy the application, If you get the authentication error, you would need to set the credentials under conf/tomcat-users.xml.

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

The CSS property touch-action may get you what you are looking for, though it may not work in all your target browsers.

html, body {
    width: 100%; height: 100%;
    overflow: hidden;
    touch-action: none;
}

var sizef = document.getElementById('input-file-id').files[0].size;
                if(sizef > 210000){
                    alert('sorry error');
                }else {
                    //action
                }   

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

@Waisky suggested:

You need to use setInterval to trigger the change, but you also need to clear the timer when the component unmounts to prevent it leaving errors and leaking memory:

If you'd like to do the same thing, using Hooks:

const [time, setTime] = useState(Date.now());

useEffect(() => {
  const interval = setInterval(() => setTime(Date.now()), 1000);
  return () => {
    clearInterval(interval);
  };
}, []);

Regarding the comments:

You don't need to pass anything inside []. If you pass time in the brackets, it means run the effect every time the value of time changes, i.e., it invokes a new setInterval every time, time changes, which is not what we're looking for. We want to only invoke setInterval once when the component gets mounted and then setInterval calls setTime(Date.now()) every 1000 seconds. Finally, we invoke clearInterval when the component is unmounted.

Note that the component gets updated, based on how you've used time in it, every time the value of time changes. That has nothing to do with putting time in [] of useEffect.

The existence of that piece of metadata is entirely dependent on the application that wrote the file. It's very common to load up JPG files with metadata (EXIF tags) about the file, such as a timestamp or camera information or geolocation. ID3 tags in MP3 files are also very common. But it's a lot less common to see this kind of metadata in video files.

If you just need a tool to read this data from files manually, GSpot might do the trick: http://www.videohelp.com/tools/Gspot

If you want to read this in code then I imagine each container format is going to have its own standards and each one will take a bit of research and implementation to support.

dictionary's setdefault is a good way to update an existing dict entry if it's there, or create a new one if it's not all in one go:

Looping style:

# This is our sample data
data = [("Milter", "Miller", 4), ("Milter", "Miler", 4), ("Milter", "Malter", 2)]

# dictionary we want for the result
dictionary = {}

# loop that makes it work
for realName, falseName, position in data:
    dictionary.setdefault(realName, {})[falseName] = position

dictionary now equals:

{'Milter': {'Malter': 2, 'Miler': 4, 'Miller': 4}}

SURE: Simply,

This is what you need :

io.to(socket.id).emit("event", data);

whenever a user joined to the server, socket details will be generated including ID. This is the ID really helps to send a message to particular people.

first we need to store all the socket.ids in array,

var people={};

people[name] =  socket.id;

here name is the receiver name. Example:

people["ccccc"]=2387423cjhgfwerwer23;

So, now we can get that socket.id with the receiver name whenever we are sending message:

for this we need to know the receivername. You need to emit receiver name to the server.

final thing is:

 socket.on('chat message', function(data){
io.to(people[data.receiver]).emit('chat message', data.msg);
});

Hope this works well for you.

Good Luck!!

No. Any valid string is a valid key. It can even have " as long as you escape it:

{"The \"meaning\" of life":42}

There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.

I am using this:

<div key={+new Date() + Math.random()}>

Yes, there are a few of them.

• ReDoc [Article on swagger.io] [GitHub] [demo] - Reinvented OpenAPI/Swagger-generated API Reference Documentation (I'm the author)

• OpenAPI GUI [GitHub] [demo] - GUI / visual editor for creating and editing OpenApi / Swagger definitions (has OpenAPI 3 support)

• Responsive Fork of SwaggerUI [GitHub] [demo]

• SwaggerUI-Angular [GitHub] [demo] - An angularJS implementation of Swagger UI

• angular-swagger-ui-material [GitHub] [demo] - Material Design template for angular-swager-ui

Hosted solutions that support swagger:

• Apiary - can import from swagger
• Readme.io - can import from swagger
• Lucybot console - supports swagger natively
• Postman - can import from swagger
• Stoplight - supports swagger natively - editing and reading

If its sufficiently close you can get away with treating them as coordinates on a flat plane. This works on say, street or city level if perfect accuracy isnt required and all you need is a rough guess on the distance involved to compare with an arbitrary limit.

$(this).parent().parent().attr('id');

Is how you would get the id of the parent's parent.

EDIT:

$(this).closest('ul').attr('id');

Is a more foolproof solution for your case.

First, open Device Manager by searching for it in the Windows search bar.

Then, click ports and right click the port the Arduino is connected to. Then, go to Port settings → Advanced. Next, select any port that is not in use and is not the port the Arduino is currently connected to. Then click OK and unplug + replug your Arduino. This works most of the time with any Arduino board.

you mentioned "entire line" , so i assumed mystring is the entire line.

if "token" in mystring:
    print(mystring)

however if you want to just get "token qwerty",

>>> mystring="""
...     qwertyuiop
...     asdfghjkl
...
...     zxcvbnm
...     token qwerty
...
...     asdfghjklñ
... """
>>> for item in mystring.split("\n"):
...  if "token" in item:
...     print (item.strip())
...
token qwerty

A little late to the party, but I think regular expressions are not the right tool for the job.

The problem is that you'll come across edge cases which would add extranous complexity to the regular expression. @est mentioned an example line:

for (int i = 0; i < 10; doSomethingTo("("));

This string literal contains an (unbalanced!) parenthesis, which breaks the logic. Apparently, you must ignore contents of string literals. In order to do this, you must take the double quotes into account. But string literals itself can contain double quotes. For instance, try this:

for (int i = 0; i < 10; doSomethingTo("\"(\\"));

If you address this using regular expressions, it'll add even more complexity to your pattern.

I think you are better off parsing the language. You could, for instance, use a language recognition tool like ANTLR. ANTLR is a parser generator tool, which can also generate a parser in Python. You must provide a grammar defining the target language, in your case C++. There are already numerous grammars for many languages out there, so you can just grab the C++ grammar.

Then you can easily walk the parser tree, searching for empty statements as while or for loop body.

Solutions:

1. List item
2. Check Exports Order
3. Enable Multi Dex
4. Check api level of views in layout. I faced same problem with searchView. I have check api level while adding searchview but added implements SearchView.OnQueryTextListener to class file.
