With a Maven build, you can add the @XmlRootElement annotation

with the "jaxb2-basics-annotate" plug-in.

Template literals may solve your issue as it will allow writing multi-line strings and string interpolation features. You can use variables or expression inside string (as given below). It's easy to insert bulk html in a reader friendly way.

I have modified the example given in question and please see it below. I am not sure how much browser compatible Template literals are. Please read about Template literals here.

var a = 1, b = 2;_x000D_
var div = document.createElement('div');_x000D_
div.setAttribute('class', 'post block bc2');_x000D_
div.innerHTML = `_x000D_
    <div class="parent">_x000D_
        <div class="child">${a}</div>_x000D_
        <div class="child">+</div>_x000D_
        <div class="child">${b}</div>_x000D_
        <div class="child">=</div>_x000D_
        <div class="child">${a + b}</div>_x000D_
    </div>_x000D_
`;_x000D_
document.getElementById('posts').appendChild(div);

Old question but I think it lacked an answer. I would use an adjacent siblings selector. This way we only write "one" line of CSS and take into consideration the space at the end or beginning, which most of the answers lacks.

li + li {
  margin-top: 10px;
}

There is a way to achieve this without type assertion, by using generics instead, which are generally a bit nicer and safer to use.

Unfortunately, getElementById is not generic, but querySelector is:

const inputValue = document.querySelector<HTMLInputElement>('#greet')!.value;

Similarly, you can use querySelectorAll to select multiple elements and use generics so TS can understand that all selected elements are of a particular type:

const inputs = document.querySelectorAll<HTMLInputElement>('.my-input');

This will produce a NodeListOf<HTMLInputElement>.

In some distributives(CentOS/OpenSuSe,...) will work only if you set JAVA_HOME in the /etc/environment.

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

ES6 way:

I use destructuring assignment for array to get first and remaining rest elements and then I'll take last five of the rest with slice method:

const cutOffFirstAndLastFive = (array) => {_x000D_
  const [first, ...rest] = array;_x000D_
  return rest.slice(-5);_x000D_
}_x000D_
_x000D_
cutOffFirstAndLastFive([1, 55, 77, 88]);_x000D_
_x000D_
console.log(_x000D_
  'Tests:',_x000D_
  JSON.stringify(cutOffFirstAndLastFive([1, 55, 77, 88])),_x000D_
  JSON.stringify(cutOffFirstAndLastFive([1, 55, 77, 88, 99, 22, 33, 44])),_x000D_
  JSON.stringify(cutOffFirstAndLastFive([1]))_x000D_
);

Is the name of your service class really IService (on the Service namespace)? What you probably had originally was a mismatch in the name of the service class in the name attribute of the <service> element.

Ultimately figured out the root of the problem.

When I create the security context manually no session object is created. Only when the request finishes processing does the Spring Security mechanism realize that the session object is null (when it tries to store the security context to the session after the request has been processed).

At the end of the request Spring Security creates a new session object and session ID. However this new session ID never makes it to the browser because it occurs at the end of the request, after the response to the browser has been made. This causes the new session ID (and hence the Security context containing my manually logged on user) to be lost when the next request contains the previous session ID.

I know this is an old post. However, I observed another instance where in the project already has Tomcat added but we still get this error. Did this to resolve that:
Alt + Enter
Project Facets
On the right, next to details, is another tab "Runtimes". The installed tomcat server will be listed there. Select it.
Save the configuration and DONE!

Hope this helps someone.

This worked for me - just changed INSERT to UPDATE for my table.

INSERT INTO Yourtable (Field1, YourDateField) VALUES('val1', (select now()))

Now my Xcode version is 6.1. But I got this warning too. it annoys me a lot . after search again and again.I found the solution.

Reason:You must have set your UILabel Lines > 1 in your Storyboard.

Solution: set your UILabel Lines attribute to 1 in Storyboard. restart your Xcode. It works for me, hope it can help more people.

If you really need to show your words more than 1 line. you should do it in the code.

//the words will show in UILabel
NSString *testString = @"Today I wanna set the line to multiple lines. bla bla ......  Today I wanna set the line to multiple lines. bla bla ......"
[self.UserNameLabel setNumberOfLines:0];
self.UserNameLabel.lineBreakMode = NSLineBreakByWordWrapping;
UIFont *font = [UIFont systemFontOfSize:12];
//Here I set the Label max width to 200, height to 60
CGSize size = CGSizeMake(200, 60);
CGRect labelRect = [testString boundingRectWithSize:size options:NSStringDrawingUsesLineFragmentOrigin attributes:[NSDictionary dictionaryWithObject:font forKey:NSFontAttributeName] context:nil];
self.UserNameLabel.frame = CGRectMake(self.UserNameLabel.frame.origin.x, self.UserNameLabel.frame.origin.y, labelRect.size.width, labelRect.size.height);
self.UserNameLabel.text = testString;

Pros

• Fixed-width layouts are much easier to use and easier to customize in terms of design.
• Widths are the same for every browser, so there is less hassle with images, forms, video and other content that are fixed-width.
• There is no need for min-width or max-width, which isn’t supported by every browser anyway.
• Even if a website is designed to be compatible with the smallest screen resolution, 800×600, the content will still be wide enough at a larger resolution to be easily legible.

Cons

• A fixed-width layout may create excessive white space for users with larger screen resolutions, thus upsetting “divine proportion,” the “Rule of Thirds,” overall balance and other design principles.
• Smaller screen resolutions may require a horizontal scroll bar, depending the fixed layout’s width.
• Seamless textures, patterns and image continuation are needed to accommodate those with larger resolutions.
• Fixed-width layouts generally have a lower overall score when it comes to usability.

I install the Oracle server and it allows to connect from the local machine with no problem. But from another Maclaptop on my home network, it can't connect using either Sql Developer or Sql Plus. After doing some research, I figured out there is this additional step you have to do:

Use the Oracle net manager. Select the Listener. Add the IP address (in my case it is 192.168.1.12) besides of the 127.0.0.1 or localhost.

This will end up add an entry to the [OracleHome]\product\11.2.0\dbhome_1\network\admin\listener.ora

• restart the listener service. (note: for me I reboot machine once to make it work)

• Use lsnrctl status to verify
  Notice the additional HOST=192.168.1.12 shows up and this is what to make remote connection to work.

Starting with Node.js 11, the url.parse and other methods of the Legacy URL API were deprecated (only in the documentation, at first) in favour of the standardized WHATWG URL API. The new API does not offer parsing the query string into an object. That can be achieved using tthe querystring.parse method:

// Load modules to create an http server, parse a URL and parse a URL query.
const http = require('http');
const { URL } = require('url');
const { parse: parseQuery } = require('querystring');

// Provide the origin for relative URLs sent to Node.js requests.
const serverOrigin = 'http://localhost:8000';

// Configure our HTTP server to respond to all requests with a greeting.
const server = http.createServer((request, response) => {
  // Parse the request URL. Relative URLs require an origin explicitly.
  const url = new URL(request.url, serverOrigin);
  // Parse the URL query. The leading '?' has to be removed before this.
  const query = parseQuery(url.search.substr(1));
  response.writeHead(200, { 'Content-Type': 'text/plain' });
  response.end(`Hello, ${query.name}!\n`);
});

// Listen on port 8000, IP defaults to 127.0.0.1.
server.listen(8000);

// Print a friendly message on the terminal.
console.log(`Server running at ${serverOrigin}/`);

If you run the script above, you can test the server response like this, for example:

curl -q http://localhost:8000/status?name=ryan
Hello, ryan!

Your function declares a constant reference to a string:

int foo(const string &myname) {
  cout << "called foo for: " << myname << endl;
  return 0;
}

A reference has some special properties, which make it a safer alternative to pointers in many ways:

• it can never be NULL
• it must always be initialised
• it cannot be changed to refer to a different variable once set
• it can be used in exactly the same way as the variable to which it refers (which means you do not need to deference it like a pointer)

How does the function signature differ from the equivalent C:

int foo(const char *myname)

There are several differences, since the first refers directly to an object, while const char* must be dereferenced to point to the data.

Is there a difference between using string *myname vs string &myname?

The main difference when dealing with parameters is that you do not need to dereference &myname. A simpler example is:

int add_ptr(int *x, int* y)
{
    return *x + *y;
}
int add_ref(int &x, int &y)
{
    return x + y;
}

which do exactly the same thing. The only difference in this case is that you do not need to dereference x and y as they refer directly to the variables passed in.

const string &GetMethodName() { ... }

What is the & doing here? Is there some website that explains how & is used differently in C vs C++?

This returns a constant reference to a string. So the caller gets to access the returned variable directly, but only in a read-only sense. This is sometimes used to return string data members without allocating extra memory.

There are some subtleties with references - have a look at the C++ FAQ on References for some more details.

• Using global static variables is not good software engineering practice.
• Converting an object's fields into primitive data types can be a hectic job.
• Using serializable is OK, but it's not performance-efficient on the Android platform.
• Parcelable is specifically designed for Android and you should use it. Here is a simple example: Passing custom objects between Android activities

You can generate Parcelable code for you class using this site.

Distinct method returns distinct elements from a sequence.

If you take a look on its implementation with Reflector, you'll see that it creates DistinctIterator for your anonymous type. Distinct iterator adds elements to Set when enumerating over collection. This enumerator skips all elements which are already in Set. Set uses GetHashCode and Equals methods for defining if element already exists in Set.

How GetHashCode and Equals implemented for anonymous type? As it stated on msdn:

Equals and GetHashCode methods on anonymous types are defined in terms of the Equals and GetHashcode methods of the properties, two instances of the same anonymous type are equal only if all their properties are equal.

So, you definitely should have distinct anonymous objects, when iterating on distinct collection. And result does not depend on how many fields you use for your anonymous type.

Create your own class. This seems odd, but a .Net type is inadequate to cover different currencies.

One important reason for creating a DLL/LIB rather than just compiling the code into an executable is reuse and relocation. The average Java or .NET application (for example) will most likely use several 3rd party (or framework) libraries. It is much easier and faster to just compile against a pre-built library, rather than having to compile all of the 3rd party code into your application. Compiling your code into libraries also encourages good design practices, e.g. designing your classes to be used in different types of applications.

A modern approach using STRING_SPLIT, requires SQL Server 2016 and above.

DECLARE @string varchar(100) = 'Hello John Smith'

SELECT
    ROW_NUMBER() OVER (ORDER BY value) AS RowNr,
    value
FROM string_split(@string, ' ')

Result:

RowNr   value
1       Hello
2       John
3       Smith

Now it is possible to get th nth element from the row number.

Two things to do:

1. Project Settings > Project compiler output > Set it as "Project path(You actual project's path)”+”\out”.

2. Project Settings > Module > Path > Choose "Inherit project compile path"

Take below reference to convert a JSON into POJO and vice-versa

Let's suppose your JSON schema looks like:

{
  "type":"object",
  "properties": {
    "dataOne": {
      "type": "string"
    },
    "dataTwo": {
      "type": "integer"
    },
    "dataThree": {
      "type": "boolean"
    }
  }
}

Then to covert into POJO, your need to decleare some classes as explained in below style:

==================================
package ;
public class DataOne
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class DataTwo
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class DataThree
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class Properties
{
    private DataOne dataOne;

    private DataTwo dataTwo;

    private DataThree dataThree;

    public void setDataOne(DataOne dataOne){
        this.dataOne = dataOne;
    }
    public DataOne getDataOne(){
        return this.dataOne;
    }
    public void setDataTwo(DataTwo dataTwo){
        this.dataTwo = dataTwo;
    }
    public DataTwo getDataTwo(){
        return this.dataTwo;
    }
    public void setDataThree(DataThree dataThree){
        this.dataThree = dataThree;
    }
    public DataThree getDataThree(){
        return this.dataThree;
    }
}

==================================
package ;
public class Root
{
    private String type;

    private Properties properties;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
    public void setProperties(Properties properties){
        this.properties = properties;
    }
    public Properties getProperties(){
        return this.properties;
    }
}

I was unable to import a Maven project with the steps suggested above until I figured out why it was not importing:

A maven project will not import if you have another Maven project with the same artifact id. Make sure that your project's artifact ID is unique in your eclipse workspace.

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

There is a new (sometime pre April 2013) option on the site that says "Clone in Windows".

This works very nicely if you already have the Windows GitHub Client as mentioned by @Tommy in his answer on this related question (How to download source in ZIP format from GitHub?).

So this question is nearly 10 years old, but it popped up on one of my searches, and I think that there are better solutions when programming in Qt: Signals & slots, timers, and finite state machines. The delays that are required can be implemented without sleeping the application in a way that interrupts other functions, and without concurrent programming and without spinning the processor - the Qt application will sleep when there are no events to process.

A hack for this is to have a sequence of timers with their timeout() signal connected to the slot for the event, which then kicks off the second timer. This is nice because it is simple. It's not so nice because it quickly becomes difficult to troubleshoot and maintain if there are logical branches, which there generally will be outside of any toy example.

QTimer

A better, more flexible option is the State Machine infrastructure within Qt. There you can configure an framework for an arbitrary sequence of events with multiple states and branches. An FSM is much easier to define, expand and maintain over time.

Qt State Machine

Just add an .htaccess file to the root folder of your site (for example, /home/domains/domain.com/htdocs/) with the following content:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

More about how this works in these pages: mod_rewrite guide (introduction, using it), reference documentation

The free and open-source program called cabextract will list and extract the contents of not just .cab-files, but Macrovision's archives too:

% cabextract /tmp/QLWREL.EXE
Extracting cabinet: /tmp/QLWREL.EXE
  extracting ikernel.dll
  extracting IsProBENT.tlb
  ....
  extracting IScript.dll
  extracting iKernel.rgs

All done, no errors.

In addition to the steps you have already taken, you will need to set the recovery mode to simple before you can shrink the log.

THIS IS NOT A RECOMMENDED PRACTICE for production systems... You will lose your ability to recover to a point in time from previous backups/log files.

See example B on this DBCC SHRINKFILE (Transact-SQL) msdn page for an example, and explanation.

< img style="vertical-align: bottom" src="blah.png" >

Works for me. Inside a parallax div as well.

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

Here is a runnable example using the mentioned indeterminate attribute:

const indeterminates = document.getElementsByClassName('indeterminate');_x000D_
indeterminates['0'].indeterminate  = true;

<form>_x000D_
  <div>_x000D_
    <input type="checkbox" checked="checked" />True_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" />False_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" class="indeterminate" />Indeterminate_x000D_
  </div>_x000D_
</form>

Just run the code snippet to see how it looks like.

Use a comma to specify two (or more) different rules:

@media screen and (max-width: 995px), 
       screen and (max-height: 700px) {
  ...
}

From https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries

Commas are used to combine multiple media queries into a single rule. Each query in a comma-separated list is treated separately from the others. Thus, if any of the queries in a list is true, the entire media statement returns true. In other words, lists behave like a logical or operator.

you have to call set and add functions on chart object before calling redraw.

chart.xAxis[0].setCategories([2,4,5,6,7], false);

chart.addSeries({
    name: "acx",
    data: [4,5,6,7,8]
}, false);

chart.redraw();

Adding a shell script e.g. run.sh makes it much more easier:

#!/usr/bin/env bash
export JAVA_PROGRAM_ARGS=`echo "$@"`
mvn exec:java -Dexec.mainClass="test.Main" -Dexec.args="$JAVA_PROGRAM_ARGS"

Then you are able to execute:

./run.sh arg1 arg2 arg3

You need to create Object for the class.

$obj = new Functions();
$var = $obj->filter($_GET['params']);

document.getElementById() only takes one argument. You can give them a class name and use getElementsByClassName() .

The modulemap solutions can be good, and are robust against SDK changes, but I've found them awkward to use in practice, and not as reliable as I'd like when handing things out to others. To try to make it all more foolproof, I went a different way:

Just copy the headers.

I know, fragile. But Apple almost never makes significant changes to CommonCrypto and I'm living the dream that they will not change it in any significant way without also finally making CommonCrypto a modular header.

By "copy the headers" I mean "cut and paste all of the headers you need into one massive header in your project just like the preprocessor would do." As an example of this that you can copy or adapt, see RNCryptor.h.

Note that all of these files are licensed under APSL 2.0, and this approach intentionally maintains the copyright and license notices. My concatenation step is licensed under MIT, and that only applies up to the next license notice).

I am not saying this is a beautiful solution, but so far it seems to have been an incredibly simple solution to both implement and support.

In order to execute multiple programs, I also needed a profiles section:

<profiles>
  <profile>
    <id>traverse</id>
    <activation>
      <property>
        <name>traverse</name>
      </property>
    </activation>
    <build>
      <plugins>
        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <configuration>
            <executable>java</executable>
            <arguments>
              <argument>-classpath</argument>
              <argument>org.dhappy.test.NeoTraverse</argument>
            </arguments>
          </configuration>
        </plugin>
      </plugins>
    </build>
  </profile>
</profiles>

This is then executable as:

mvn exec:exec -Ptraverse

You can build your own contextmanager to check if the exception was raised.

import contextlib

@contextlib.contextmanager
def raises(exception):
    try:
        yield 
    except exception as e:
        assert True
    else:
        assert False

And then you can use raises like this:

with raises(Exception):
    print "Hola"  # Calls assert False

with raises(Exception):
    raise Exception  # Calls assert True

If you are using pytest, this thing is implemented already. You can do pytest.raises(Exception):

Example:

def test_div_zero():
    with pytest.raises(ZeroDivisionError):
        1/0

And the result:

pigueiras@pigueiras$ py.test
================= test session starts =================

If you're looking for short answer:

In the case of using java.util.Date, Java doesn't really know how to directly relate to SQL types. This is when @Temporal comes into play. It's used to specify the desired SQL type.

Source: Baeldung

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

Here is a handy function you can use to help with identifying your opencv matrices at runtime. I find it useful for debugging, at least.

string type2str(int type) {
  string r;

  uchar depth = type & CV_MAT_DEPTH_MASK;
  uchar chans = 1 + (type >> CV_CN_SHIFT);

  switch ( depth ) {
    case CV_8U:  r = "8U"; break;
    case CV_8S:  r = "8S"; break;
    case CV_16U: r = "16U"; break;
    case CV_16S: r = "16S"; break;
    case CV_32S: r = "32S"; break;
    case CV_32F: r = "32F"; break;
    case CV_64F: r = "64F"; break;
    default:     r = "User"; break;
  }

  r += "C";
  r += (chans+'0');

  return r;
}

If M is a var of type Mat you can call it like so:

string ty =  type2str( M.type() );
printf("Matrix: %s %dx%d \n", ty.c_str(), M.cols, M.rows );

Will output data such as:

Matrix: 8UC3 640x480 
Matrix: 64FC1 3x2 

Its worth noting that there are also Matrix methods Mat::depth() and Mat::channels(). This function is just a handy way of getting a human readable interpretation from the combination of those two values whose bits are all stored in the same value.

If your subplots also have titles, you may need to adjust the main title size:

I use Windows 10 machine working with PHP 8 and Lavarel 8 and I got the same error, I used the following command :-

composer update --ignore-platform-reqs

to update all the packages regardless of the version conflicts.

Although the other answers are quite helpful, just wanted to share my experience as well.

I faced the issue when I had deleted a table whose id was already being referenced as foreign key in other tables (with data) and tried to recreate/import the table with some additional columns.

The query for recreation (generated in phpMyAdmin) looked like the following:

CREATE TABLE `the_table` (
  `id` int(11) NOT NULL,            /* No PRIMARY KEY index */  
  `name` varchar(255) NOT NULL,
  `name_fa` varchar(255) NOT NULL,
  `name_pa` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

... /* SOME DATA DUMP OPERATION */

ALTER TABLE `the_table`
  ADD PRIMARY KEY (`id`), /* PRIMARY KEY INDEX */
  ADD UNIQUE KEY `uk_acu_donor_name` (`name`);

As you may notice, the PRIMARY KEY index was set after the creation (and insertion of data) which was causing the problem.

Solution

The solution was to add the PRIMARY KEY index on table definition query for the id which was being referenced as foreign key, while also removing it from the ALTER TABLE part where indexes were being set:

CREATE TABLE `the_table` (
  `id` int(11) NOT NULL PRIMARY KEY,            /* <<== PRIMARY KEY INDEX ON CREATION */  
  `name` varchar(255) NOT NULL,
  `name_fa` varchar(255) NOT NULL,
  `name_pa` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

If you want an executable to run, use Windows Scheduled Tasks. I'm going to assume (perhaps erroneously) that you want a method to run in your current program.

Why not just have a thread running continuously storing the last date that the method was called?

Have it wake up every minute (for example) and, if the current time is greater than the specified time and the last date stored is not the current date, call the method then update the date.

Dumping a database with a specific encoding and try to restore it on another database with a different encoding could result in data corruption. Data encoding must be set BEFORE any data is inserted into the database.

Check this : When copying any other database, the encoding and locale settings cannot be changed from those of the source database, because that might result in corrupt data.

And this : Some locale categories must have their values fixed when the database is created. You can use different settings for different databases, but once a database is created, you cannot change them for that database anymore. LC_COLLATE and LC_CTYPE are these categories. They affect the sort order of indexes, so they must be kept fixed, or indexes on text columns would become corrupt. (But you can alleviate this restriction using collations, as discussed in Section 22.2.) The default values for these categories are determined when initdb is run, and those values are used when new databases are created, unless specified otherwise in the CREATE DATABASE command.

I would rather rebuild everything from the begining properly with a correct local encoding on your debian OS as explained here :

su root

Reconfigure your local settings :

dpkg-reconfigure locales

Choose your locale (like for instance for french in Switzerland : fr_CH.UTF8)

Uninstall and clean properly postgresql :

apt-get --purge remove postgresql\*
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

Re-install postgresql :

aptitude install postgresql-9.1 postgresql-contrib-9.1 postgresql-doc-9.1

Now any new database will be automatically be created with correct encoding, LC_TYPE (character classification), and LC_COLLATE (string sort order).

It can be done through "Import/Export Data..." in SQL Server Management Studio

You could use moment.js with Postman to give you that timestamp format.

You can add this to the pre-request script:

const moment = require('moment');
pm.globals.set("today", moment().format("MM/DD/YYYY"));

Then reference {{today}} where ever you need it.

If you add this to the Collection Level Pre-request Script, it will be run for each request in the Collection. Rather than needing to add it to all the requests individually.

For more information about using moment in Postman, I wrote a short blog post: https://dannydainton.com/2018/05/21/hold-on-wait-a-moment/

I actually wrote a function recently that would check for a substring within an array that will come in handy in this situation.

function strInArray($haystack, $needle) {
    $i = 0;
    foreach ($haystack as $value) {
        $result = stripos($value,$needle);
        if ($result !== FALSE) return TRUE;
        $i++;
    }
    return FALSE;
}

$array = array(12,43,66,21,56,43,43,78,78,100,43,43,43,21);

for ($i = 0; $i < count($array); $i++) {
    if (strInArray($array,$array[$i])) {
        unset($array[$i]);
    }
}
var_dump($array);

Below code is nice.. It was given by somebody else named aaronbd in this forum

<?php

$conn = new mysqli('localhost', 'username', 'password', 'database') 
or die ('Cannot connect to db');

    $result = $conn->query("select id, name from table");

    echo "<html>";
    echo "<body>";
    echo "<select name='id'>";

    while ($row = $result->fetch_assoc()) {

                  unset($id, $name);
                  $id = $row['id'];
                  $name = $row['name']; 
                  echo '<option value="'.$id.'">'.$name.'</option>';

}

    echo "</select>";
    echo "</body>";
    echo "</html>";
?> 

You can use the Axes.set_yscale method. That allows you to change the scale after the Axes object is created. That would also allow you to build a control to let the user pick the scale if you needed to.

The relevant line to add is:

ax.set_yscale('log')

You can use 'linear' to switch back to a linear scale. Here's what your code would look like:

import pylab
import matplotlib.pyplot as plt
a = [pow(10, i) for i in range(10)]
fig = plt.figure()
ax = fig.add_subplot(2, 1, 1)

line, = ax.plot(a, color='blue', lw=2)

ax.set_yscale('log')

pylab.show()

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

to also check blank string, I suggest following

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:if test="${empty fn:trim(var1)}">

</c:if>

It also handles nulls

Context

If you

1. want to force all users to have LF line endings for text files and
2. you cannot ensure that all users change their git config,

you can do that starting with git 2.10. 2.10 or later is required, because 2.10 fixed the behavior of text=auto together with eol=lf. Source.

Solution

Put a .gitattributes file in the root of your git repository having following contents:

* text=auto eol=lf

Commit it.

Optional tweaks

You can also add an .editorconfig in the root of your repository to ensure that modern tooling creates new files with the desired line endings.

# EditorConfig is awesome: http://EditorConfig.org

# top-most EditorConfig file
root = true

# Unix-style newlines with a newline ending every file
[*]
end_of_line = lf
insert_final_newline = true

Here is something that i have been trying.(Insertion sort- not the best way to sort but does the work)

def sort(list):
    for index in range(1,len(list)):
        value = list[index]
        i = index-1
        while i>=0:
            if value < list[i]:
                list[i+1] = list[i]
                list[i] = value
                i -= 1
            else:
                break

I know it's an old question, but it's a good one, so how about this?

unsigned short int x = 65529U;
short int y = *(short int*)&x;

printf("%d\n", y);

Just look up the files you deleted, inside Recycle Bin. Right click on it and do restore as you do normally with other deleted files. It is similar as you do normally because VS code also uses normal trash of your system.

from delorean import Delorean
now = datetime.datetime.now()
d = Delorean(now, timezone='US/Pacific')

>>> now    
datetime.datetime(2015, 3, 26, 19, 46, 40, 525703)

>>> d.truncate('second')
Delorean(datetime=2015-03-26 19:46:40-07:00, timezone='US/Pacific')

>>> d.truncate('minute')
Delorean(datetime=2015-03-26 19:46:00-07:00, timezone='US/Pacific')

>>> d.truncate('hour')
Delorean(datetime=2015-03-26 19:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('day')
Delorean(datetime=2015-03-26 00:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('month')
Delorean(datetime=2015-03-01 00:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('year')
Delorean(datetime=2015-01-01 00:00:00-07:00, timezone='US/Pacific')

and if you want to get datetime value back:

>>> d.truncate('year').datetime
datetime.datetime(2015, 1, 1, 0, 0, tzinfo=<DstTzInfo 'US/Pacific' PDT-1 day, 17:00:00 DST>)

$listOfUsernames = @("user1", "user2", "etc", "and so on")
Get-EventLog -LogName Security | 
    where { $_.Username -notmatch (
        '(' + [string]::Join(')|(', $listOfUsernames) + ')') }

It's a little crazy I'll grant you, and it fails to escape the usernames (in the unprobable case a username uses a Regex escape character like '\' or '(' ), but it works.

As "slipsec" mentioned above, use -notcontains if possible.

A String is a type of Object. So any method that accepts Object as parameter will surely accept String also. Please provide more of your code if you still do not find a solution.

I think you are looking for the Jquery Load function. You would just use that function with an onclick function tied to the a tag or a button if you like.

parseInt(value) or parseFloat(value)

This will work nicely.

after writing the jquery code perform this validation in your route or in controller.

$.ajax({
url: "/id/edit",
data:
name:name,
method:'get',
success:function(data){
  console.log(data);}
});

Route::get('/', function(){
if(Request::ajax()){
  return 'it's ajax request';}
});

The exec built-in command mirrors functions in the kernel, there are a family of them based on execve, which is usually called from C.

exec replaces the current program in the current process, without forking a new process. It is not something you would use in every script you write, but it comes in handy on occasion. Here are some scenarios I have used it;

1. We want the user to run a specific application program without access to the shell. We could change the sign-in program in /etc/passwd, but maybe we want environment setting to be used from start-up files. So, in (say) .profile, the last statement says something like:

    exec appln-program
   

   so now there is no shell to go back to. Even if appln-program crashes, the end-user cannot get to a shell, because it is not there - the exec replaced it.

2. We want to use a different shell to the one in /etc/passwd. Stupid as it may seem, some sites do not allow users to alter their sign-in shell. One site I know had everyone start with csh, and everyone just put into their .login (csh start-up file) a call to ksh. While that worked, it left a stray csh process running, and the logout was two stage which could get confusing. So we changed it to exec ksh which just replaced the c-shell program with the korn shell, and made everything simpler (there are other issues with this, such as the fact that the ksh is not a login-shell).

3. Just to save processes. If we call prog1 -> prog2 -> prog3 -> prog4 etc. and never go back, then make each call an exec. It saves resources (not much, admittedly, unless repeated) and makes shutdown simplier.

You have obviously seen exec used somewhere, perhaps if you showed the code that's bugging you we could justify its use.

Edit: I realised that my answer above is incomplete. There are two uses of exec in shells like ksh and bash - used for opening file descriptors. Here are some examples:

exec 3< thisfile          # open "thisfile" for reading on file descriptor 3
exec 4> thatfile          # open "thatfile" for writing on file descriptor 4
exec 8<> tother           # open "tother" for reading and writing on fd 8
exec 6>> other            # open "other" for appending on file descriptor 6
exec 5<&0                 # copy read file descriptor 0 onto file descriptor 5
exec 7>&4                 # copy write file descriptor 4 onto 7
exec 3<&-                 # close the read file descriptor 3
exec 6>&-                 # close the write file descriptor 6

Note that spacing is very important here. If you place a space between the fd number and the redirection symbol then exec reverts to the original meaning:

  exec 3 < thisfile       # oops, overwrite the current program with command "3"

There are several ways you can use these, on ksh use read -u or print -u, on bash, for example:

read <&3
echo stuff >&4

The lean option tells Mongoose to skip hydrating the result documents. This makes queries faster and less memory intensive, but the result documents are plain old JavaScript objects (POJOs), not Mongoose documents.

const leanDoc = await MyModel.findOne().lean();

not necessary to use JSON.parse() method

That because your csv file is in invalid format, maybe the line break in your text file is not the \n or \r

and, using c/c++ to parse text is not a good idea. try awk:

 $awk -F"," '{print "ID="$1"\tName="$2"\tAge="$3"\tGender="$4}' 1.csv
 ID=0   Name=Filipe Age=19  Gender=M
 ID=1   Name=Maria  Age=20  Gender=F
 ID=2   Name=Walter Age=60  Gender=M

<script type="text/javascript">
$(document).ready(function(){
  refreshTable();
});

function refreshTable(){
    $('#tableHolder').load('getTable.php', function(){
       setTimeout(refreshTable, 5000);
    });
}
</script>

The second answer (at the time of writing) gives :

var values = keys.map(function(v) { return myHash[v]; });

But I prefer using jQuery's own $.map :

var values = $.map(myHash, function(v) { return v; });

Since jQuery takes care of cross-browser compatibility. Plus it's shorter :)

At any rate, I always try to be as functional as possible. One-liners are nicers than loops.

in ts

 isArray(obj: any) 
{
    return Array.isArray(obj)
  }

in html

(photos == undefined || !(isArray(photos) && photos.length > 0) )

Imread uses PIL library, if the library is installed use : "from scipy.ndimage import imread"

Source: http://docs.scipy.org/doc/scipy-0.17.0/reference/generated/scipy.ndimage.imread.html

-Ldir
Add directory dir to the list of directories to be searched for -l.

SELECT
  category,
  COUNT(*) AS `num`
FROM
  posts
GROUP BY
  category

Usually, you expand the parameters passed to a sub using the @_ variable:

sub test{
  my ($a, $b, $c) = @_;
  ...
}

# call the test sub with the parameters
test('alice', 'bob', 'charlie');

That's the way claimed to be correct by perlcritic.

No. Actually it's the "same" as

char array[] = {'O', 'n', 'e', ..... 'i','c','\0');

Every character is a separate element, with an additional \0 character as a string terminator.

I quoted "same", because there are some differences between char * array and char array[]. If you want to read more, take a look at C: differences between char pointer and array

If you need to duplicate more than a few redirects, you might consider using a map:

# map is outside of server block
map $uri $redirect_uri {
    ~^/issue1/?$    http://example.com/shop/issues/custom_isse_name1;
    ~^/issue2/?$    http://example.com/shop/issues/custom_isse_name2;
    ~^/issue3/?$    http://example.com/shop/issues/custom_isse_name3;
    # ... or put these in an included file
}

location / {
    try_files $uri $uri/ @redirect-map;
}

location @redirect-map {
    if ($redirect_uri) {  # redirect if the variable is defined
        return 301 $redirect_uri;
    }
}

It was not working for me when tried to use:

JOptionPane.showConfirmDialog(...)

But - I found a solution ! Very primitive, but works.

Just jump to the field by java.awt.Robot using key "Tab". For example:

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_TAB);
robot.delay(100);
robot.keyRelease(KeyEvent.VK_TAB);

If you should press multiple times on "Tab" to get your Component you can use below method:

GUIUtils.pressTab(3);

Definition:

public static void pressTab(int amountOfClickes)
{
    SwingUtilities.invokeLater(new Runnable()
    {
        public void run()
        {
            try
            {
                Robot robot = new Robot();
                int i = amountOfClickes;
                while (i-- > 0)
                {
                    robot.keyPress(KeyEvent.VK_TAB);
                    robot.delay(100);
                    robot.keyRelease(KeyEvent.VK_TAB);
                }
            }
            catch (AWTException e)
            {
                System.out.println("Failed to use Robot, got exception: " + e.getMessage());
            }
        }
    });
}

If your Component location is dynamic, you can run over the while loop without limitation, but add some focus listener on the component, to stop the loop once arrived to it.

Inspired by Jon's answer, how about this one

word = 'hello'
q = deque(word)
''.join(q.pop() for _ in range(len(word)))

In case you want to pass error strings, here is an example from Errors and Exceptions (Python 2.6)

>>> try:
...    raise Exception('spam', 'eggs')
... except Exception as inst:
...    print type(inst)     # the exception instance
...    print inst.args      # arguments stored in .args
...    print inst           # __str__ allows args to printed directly
...    x, y = inst          # __getitem__ allows args to be unpacked directly
...    print 'x =', x
...    print 'y =', y
...
<type 'exceptions.Exception'>
('spam', 'eggs')
('spam', 'eggs')
x = spam
y = eggs

Use utcOffset function.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).utcOffset(10 * 60); //set timezone offset in minutes
console.log(localDate.format()); //2015-01-30T20:00:00+10:00

An alterntive is to use an enum and a component class that extends the standard RadioButton.

public enum Genders
{
    Male,
    Female
}

[ToolboxBitmap(typeof(RadioButton))]
public partial class GenderRadioButton : RadioButton
{
    public GenderRadioButton()
    {
        InitializeComponent();
    }

    public GenderRadioButton (IContainer container)
    {
        container.Add(this);

        InitializeComponent();
    }

    public Genders gender{ get; set; }
}

Use a common event handler for the GenderRadioButtons

private void Gender_CheckedChanged(Object sender, EventArgs e)
{
    if (((RadioButton)sender).Checked)
    {
        //get selected value
        Genders myGender = ((GenderRadioButton)sender).Gender;
        //get the name of the enum value
        string GenderName = Enum.GetName(typeof(Genders ), myGender);
        //do any work required when you change gender
        switch (myGender)
        {
            case Genders.Male:
                break;
            case Genders.Female:
                break;
            default:
                break;
        }
    }
}

SHTML is a file extension that lets the web server know the file should be processed as using Server Side Includes (SSI).

(HTML is...you know what it is, and DHTML is Microsoft's name for Javascript+HTML+CSS or something).

You can use SSI to include a common header and footer in your pages, so you don't have to repeat code as much. Changing one included file updates all of your pages at once. You just put it in your HTML page as per normal.

It's embedded in a standard XML comment, and looks like this:

<!--#include virtual="top.shtml" -->

It's been largely superseded by other mechanisms, such as PHP includes, but some hosting packages still support it and nothing else.

You can read more in this Wikipedia article.

Use of the String.toString:

Whenever you require to explore the constructor called value in the String form, you can simply use String.toString... for an example...

package pack1;

import java.util.*;

class Bank {

    String n;
    String add;
    int an;
    int bal;
    int dep;

    public Bank(String n, String add, int an, int bal) {

        this.add = add;
        this.bal = bal;
        this.an = an;
        this.n = n;

    }

    public String toString() {
        return "Name of the customer.:" + this.n + ",, "
                + "Address of the customer.:" + this.add + ",, " + "A/c no..:"
                + this.an + ",, " + "Balance in A/c..:" + this.bal;
    }
}

public class Demo2 {

    public static void main(String[] args) {

        List<Bank> l = new LinkedList<Bank>();

        Bank b1 = new Bank("naseem1", "Darbhanga,bihar", 123, 1000);
        Bank b2 = new Bank("naseem2", "patna,bihar", 124, 1500);
        Bank b3 = new Bank("naseem3", "madhubani,bihar", 125, 1600);
        Bank b4 = new Bank("naseem4", "samastipur,bihar", 126, 1700);
        Bank b5 = new Bank("naseem5", "muzafferpur,bihar", 127, 1800);
        l.add(b1);
        l.add(b2);
        l.add(b3);
        l.add(b4);
        l.add(b5);
        Iterator<Bank> i = l.iterator();
        while (i.hasNext()) {
            System.out.println(i.next());
        }
    }

}

... copy this program into your Eclipse, and run it... you will get the ideas about String.toString...

In general, CSS properties are converted to JavaScript by making them camelCase without any dashes. So background-color becomes backgroundColor.

function setColor(element, color)
{
    element.style.backgroundColor = color;
}

// where el is the concerned element
var el = document.getElementById('elementId');
setColor(el, 'green');

Why not using: SELECT home, MAX(datetime) AS MaxDateTime,player,resource FROM topten GROUP BY home Did I miss something?

system("COLOR 0A");'

where 0A is a combination of background and font color 0

This question is very similar to:

Capture console exit C#

Here is how I solved this problem, and dealt with the user hitting the X as well as Ctrl-C. Notice the use of ManualResetEvents. These will cause the main thread to sleep which frees the CPU to process other threads while waiting for either exit, or cleanup. NOTE: It is necessary to set the TerminationCompletedEvent at the end of main. Failure to do so causes unnecessary latency in termination due to the OS timing out while killing the application.

I'm just starting some string manipulations and found this question. I was probably trying to do something like the OP, "usual me". The previous answers did not clear up my confusion, but after thinking a little about it I finally "got it".

As long as a, b, c, d, and e have the same value, they reference to the same place. Memory is saved. As soon as the variable start to have different values, they get start to have different references. My learning experience came from this code:

import copy
a = 'hello'
b = str(a)
c = a[:]
d = a + ''
e = copy.copy(a)

print map( id, [ a,b,c,d,e ] )

print a, b, c, d, e

e = a + 'something'
a = 'goodbye'
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e

The printed output is:

[4538504992, 4538504992, 4538504992, 4538504992, 4538504992]

hello hello hello hello hello

[6113502048, 4538504992, 4538504992, 4538504992, 5570935808]

goodbye hello hello hello hello something

yourList = ["a", "b", "a", "c", "c", "a", "c"]

expected outputs {a: 3, b: 1,c:3}

duplicateFrequencies = {}
for i in set(yourList):
    duplicateFrequencies[i] = yourList.count(i)

Cheers!! Reference

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

I'd use:

var stringNumber = "1234"
var numberFromString = stringNumber.toInt()
println(numberFromString)

Note toInt():

If the string represents an integer that fits into an Int, returns the corresponding integer.

This worked for me, returns the timestamp in GMT!

    Date currDate;
    SimpleDateFormat dateFormatGmt = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss");
    dateFormatGmt.setTimeZone(TimeZone.getTimeZone("GMT"));
    SimpleDateFormat dateFormatLocal = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss");

    long currTime = 0;
    try {

        currDate = dateFormatLocal.parse( dateFormatGmt.format(new Date()) );
        currTime = currDate.getTime();
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

You can use Q objects for this. They can be negated with the ~ operator and combined much like normal Python expressions:

from myapp.models import Entry
from django.db.models import Q

Entry.objects.filter(~Q(id=3))

will return all entries except the one(s) with 3 as their ID:

[<Entry: Entry object>, <Entry: Entry object>, <Entry: Entry object>, ...]

To get 'dataX = urllib.urlopen(url).read()' working in python3 (this would have been correct for python2) you must just change 2 little things.

1: The urllib statement itself (add the .request in the middle):

dataX = urllib.request.urlopen(url).read()

2: The import statement preceding it (change from 'import urlib' to:

import urllib.request

And it should work in python3 :)

I encountered the same problem when I was trying to compile a sample project provided by Apple. In the end I figured out that apparently they pre-compiled the sample code before shipping them to developers, so the binary had their signature.

The way to solve it is simple, just delete all the built binaries and re-compile using your own bundle identifier and you should be fine.

Just go to the menu bar, click on [Product] -> [Clean Build Folder] to delete all compiled binaries

Clean Build Folder

Here is another concrete example.It is for a shared library. The shared library's main function is to communicate with a smart card reader. But it can also receive 'configuration information' at runtime over udp. The udp is handled by a thread which MUST be started at init time.

__attribute__((constructor))  static void startUdpReceiveThread (void) {
    pthread_create( &tid_udpthread, NULL, __feigh_udp_receive_loop, NULL );
    return;

  }

The library was written in c.

You can use devicecheck (in Swift 4) Apple documentation

func sendEphemeralToken() {
        //check if DCDevice is available (iOS 11)

        //get the **ephemeral** token
        DCDevice.current.generateToken {
        (data, error) in
        guard let data = data else {
            return
        }

        //send **ephemeral** token to server to 
        let token = data.base64EncodedString()
        //Alamofire.request("https://myServer/deviceToken" ...
    }
}

Typical usage:

Typically, you use the DeviceCheck APIs to ensure that a new user has not already redeemed an offer under a different user name on the same device.

Server action needs:

See WWDC 2017 — Session 702 (24:06)

more from Santosh Botre article - Unique Identifier for the iOS Devices

Your associated server combines this token with an authentication key that you receive from Apple and uses the result to request access to the per-device bits.

Why do we have to write that 5 line code ?

public class EnumTest {
public enum MyEnum {
    A, B, C, D;
}

@Test
public void test() throws Exception {
    MyEnum.valueOf("A"); //gives you A
    //this throws ILlegalargument without having to do any lookup
    MyEnum.valueOf("RADD"); 
}
}

int main()
{
    unsigned long long d;
    scanf("%llu",&d);
    printf("%llu",d);
    getch();
}

This will be helpful . . .

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

I don't think any of the current answers really do what you said you want. (Correction: I now see that @Gareth Latty / @Lattyware has incorporated my answer into his own as an "Edit" near the end.)

Anyway, here's my take:

Say these are the tab-separated values in your input file:

1   2   3   4   5
6   7   8   9   10
11  12  13  14  15
16  17  18  19  20

then this:

with open("tab-separated-values.txt") as inp:
    print( list(zip(*(line.strip().split('\t') for line in inp))) )

would produce the following:

[('1', '6', '11', '16'), 
 ('2', '7', '12', '17'), 
 ('3', '8', '13', '18'), 
 ('4', '9', '14', '19'), 
 ('5', '10', '15', '20')]

As you can see, it put the k-th element of each row into the k-th array.

One more way of running an R script from the command line would be:

R < scriptName.R --no-save  

or with --save.

See also What's the best way to use R scripts on the command line (terminal)?.

A difference in Firefox (12.0) is that on a page rendered from a POST, reload() will pop up a warning and do a re-post, while a URL assignment will do a GET.

Google Chrome does a GET for both.

I solved the problem in june of 2017 changing the play-services versions for the latest firebase versions (9.6.1). When I used the latest play-services version (10.2.4) I got that error. The code in the gradle looks like this:

Before

compile 'com.google.android.gms:play-services-maps:10.2.4'
compile 'com.google.android.gms:play-services-places:10.2.4'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'

After

compile 'com.google.android.gms:play-services-maps:9.6.1'
compile 'com.google.android.gms:play-services-places:9.6.1'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'

Xcode 8 beta 2 • Swift 3

let myString = "Hello World"
let myRange = myString.startIndex..<myString.index(myString.startIndex, offsetBy: 5)
let mySubString = myString.substring(with: myRange)   // Hello

Xcode 7 • Swift 2.0

let myString = "Hello World"
let myRange = Range<String.Index>(start: myString.startIndex, end: myString.startIndex.advancedBy(5))

let mySubString = myString.substringWithRange(myRange)   // Hello

or simply

Sometimes there is some error in the local Maven repo. So please close your eclipse and delete the jar spring-webmvc from your local .m2 then open Eclipse and on the project press Update Maven Dependencies.

Then Eclipse will download the dependency again for you. That how I fixed the same problem.

If you put all your values in an array, at least you can use string.Join.

string[] myValues = new string[] { ... };
string csvString = string.Join(",", myValues);

You can also use the overload of string.Join that takes params string as the second parameter like this:

string csvString = string.Join(",", value1, value2, value3, ...);

The file msrdo20.dll is missing from the installation.

According to the Support Statement for Visual Basic 6.0 on Windows Vista, Windows Server 2008 and Windows 7 this file should be distributed with the application.

I'm not sure why it isn't, but my solution is to place the file somewhere on the machine, and register it using regsvr32 in the command line, eg:

regsvr32 c:\windows\system32\msrdo20.dll

In an ideal world you would package this up with the redistributable.

I've had better luck with calling the gotoDate in the viewRender callback:

$('#calendar').fullCalendar({
  firstDay: 0,
  defaultView: 'basicWeek',
  header: {
    left: '',
    center: 'basicDay,basicWeek,month',
    right:  'today prev,next'
  },
  viewRender: function(view, element) {
    $('#calendar').fullCalendar( 'gotoDate', 2014, 4, 24 );
  }
});

Calling gotoDate outside of the callback didn't have the expected results due to a race condition.

For WPF, there isn't a way. You have to mimic it. See this example. A secondary (flaky solution) is to host a WinForms user control that inherits from TextBox and send the EM_SETCUEBANNER message to the edit control. ie.

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr SendMessage(IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam);

private const Int32 ECM_FIRST = 0x1500;
private const Int32 EM_SETCUEBANNER = ECM_FIRST + 1;

private void SetCueText(IntPtr handle, string cueText) {
    SendMessage(handle, EM_SETCUEBANNER, IntPtr.Zero, Marshal.StringToBSTR(cueText));
}

public string CueText {
    get {
        return m_CueText;
    } 
    set {
        m_CueText = value;
        SetCueText(this.Handle, m_CueText);
}

Also, if you want to host a WinForm control approach, I have a framework that already includes this implementation called BitFlex Framework, which you can download for free here.

Here is an article about BitFlex if you want more information. You will start to find that if you are looking to have Windows Explorer style controls that this generally never comes out of the box, and because WPF does not work with handles generally you cannot write an easy wrapper around Win32 or an existing control like you can with WinForms.

Screenshot:

I recently dealt with this problem, and the cause of the problem turned out to be that the root certificate on the SMTP server that I was connecting to was the Sectigo root certificate that recently expired.

If you're connecting to the SMTP server by SSL/TLS or STARTTLS, and you've not changed anything recently in the environment where your PHPMailer script is running, and this problem suddenly occurred - then you might want to check for an expired or invalid certificate somewhere in the certificate chain on the server.

You can view the server's certificate chain using openssl s_client.

For SSL/TLS on port 465:

openssl s_client -connect server.domain.tld:465 | openssl x509 -text

For STARTTLS on port 587:

openssl s_client -starttls smtp -crlf -connect server.domain.tld:587 | openssl x509 -text

You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.

$data = array(
    array(
        "title" => "Another title",
        "date"  => "Fri, 17 Jun 2011 08:55:57 +0200"
    ),
    array(
        "title" => "My title",
        "date"  => "Mon, 16 Jun 2010 06:55:57 +0200"
    )
);

function sortFunction( $a, $b ) {
    return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);

On your own system, try

install.packages("foo", dependencies=...)

with the dependencies= argument is documented as

dependencies: logical indicating to also install uninstalled packages
      which these packages depend on/link to/import/suggest (and so
      on recursively).  Not used if ‘repos = NULL’.  Can also be a
      character vector, a subset of ‘c("Depends", "Imports",
      "LinkingTo", "Suggests", "Enhances")’.

      Only supported if ‘lib’ is of length one (or missing), so it
      is unambiguous where to install the dependent packages.  If
      this is not the case it is ignored, with a warning.

      The default, ‘NA’, means ‘c("Depends", "Imports",
      "LinkingTo")’.

      ‘TRUE’ means (as from R 2.15.0) to use ‘c("Depends",
      "Imports", "LinkingTo", "Suggests")’ for ‘pkgs’ and
      ‘c("Depends", "Imports", "LinkingTo")’ for added
      dependencies: this installs all the packages needed to run
      ‘pkgs’, their examples, tests and vignettes (if the package
      author specified them correctly).

so you probably want a value TRUE.

In your package, list what is needed in Depends:, see the Writing R Extensions manual which is pretty clear on this.

var a = 10;

myFunction();

function myFunction(){
   a = 20;
}

alert("Value of 'a' outside the function " + a); //outputs 20

Changing Python:Language Server to 'Jedi' worked for me. It was 'Windows' initially.

I created a bit of a hybrid approach between Paul & Adam's approach:

The link that opens the array of links is already in the html. The jquery just creates the array of links and opens each one when the "open-all" button is clicked:

HTML:

<ul class="links">
<li><a href="http://www.google.com/"></a></li>
<li><a href="http://www.yahoo.com/"></a></li>
</ul>

<a id="open-all" href="#">OPEN ALL</a>

JQUERY:

$(function() { // On DOM content ready...
    var hrefs = [];

    $('.links a').each(function() {
        hrefs.push(this.href); // Store the URLs from the links...
    });

    $('#open-all').click(function() {
        for (var i in hrefs) {
            window.open(hrefs[i]); // ...that opens each stored link in its own window when clicked...
        }
    });
});

You can check it out here: https://jsfiddle.net/daveaseeman/vonob51n/1/

what about array_search? seems it quite faster than foreach according to https://gist.github.com/Ocramius/1290076 ..

if( array_search("Irix", $a) === true) 
{
    echo "Got Irix";
}

You could also change resolution of your bluestacks emulator. For example from 800x1280 to 1280x800

Here are instructions for how to change the screen resolution.

To change screen resolution in BlueStacks Android emulator you need to edit two registry items:

1. Run regedit.exe

2. Set new resolution (in decimal):

HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0\Height

and

HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0\Width

Kill all BlueStacks processes.

Restart BlueStacks

From the documentation on expandtab:

To insert a real tab when expandtab is on, use CTRL-V<Tab>. See also :retab and ins-expandtab.
This option is reset when the paste option is set and restored when the paste option is reset.

So if you have a mapping for toggling the paste option, e.g.

set pastetoggle=<F2>

you could also do <F2>Tab<F2>.

The only thing which worked for me is this

fetchData()
  .subscribe(
    (data) => {
       //Called when success
     },
    (error) => {
       //Called when error
    }
  ).add(() => {
       //Called when operation is complete (both success and error)
  });

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

Found an answer here.

So:

• Command key is 55
• Shift is 56
• Caps Lock 57
• Option is 58
• Control is 59.

here is my solution for slide & fade effect:

   // Add slideup & fadein animation to dropdown
   $('.dropdown').on('show.bs.dropdown', function(e){
      var $dropdown = $(this).find('.dropdown-menu');
      var orig_margin_top = parseInt($dropdown.css('margin-top'));
      $dropdown.css({'margin-top': (orig_margin_top + 10) + 'px', opacity: 0}).animate({'margin-top': orig_margin_top + 'px', opacity: 1}, 300, function(){
         $(this).css({'margin-top':''});
      });
   });
   // Add slidedown & fadeout animation to dropdown
   $('.dropdown').on('hide.bs.dropdown', function(e){
      var $dropdown = $(this).find('.dropdown-menu');
      var orig_margin_top = parseInt($dropdown.css('margin-top'));
      $dropdown.css({'margin-top': orig_margin_top + 'px', opacity: 1, display: 'block'}).animate({'margin-top': (orig_margin_top + 10) + 'px', opacity: 0}, 300, function(){
         $(this).css({'margin-top':'', display:''});
      });
   });

This answer solves the problem by creating a duplicate annotated tag — including all tag info such as tagger, message, and tag date — by using the tag info from the existing tag.

SOURCE_TAG=old NEW_TAG=new; deref() { git for-each-ref \
"refs/tags/$SOURCE_TAG" --format="%($1)" ; }; \
GIT_COMMITTER_NAME="$(deref taggername)" \
GIT_COMMITTER_EMAIL="$(deref taggeremail)" \
GIT_COMMITTER_DATE="$(deref taggerdate)" git tag "$NEW_TAG" \
"$(deref "*objectname")" -a -m "$(deref contents)"

git tag -d old

git push origin new :old

Update the SOURCE_TAG and NEW_TAG values to match your old and new tag names.

Motivation

From what I can tell, all the other answers have subtle gotchas, or don't fully duplicate everything about the tag (e.g. they use a new tag date, or the current user's info as the tagger). Many of them call out the re-tagging warning, despite that not applying to this scenario (it's for moving a tag name to a different commit, not for renaming to a differently named tag). I've done some digging, and I believe I've pieced together a solution that addresses these concerns.

Goal

The git-tag documentation specifies the parts of an annotated tag. To truly be an indistinguishable rename, these elements should be the same in the new tag.

Tag objects (created with -a, -s, or -u) are called "annotated" tags; they contain a creation date, the tagger name and e-mail, a tagging message, and an optional GnuPG signature.

I'm only addressing unsigned tags in this answer, though it should be a simple matter to extend this solution to signed tags.

Procedure

An annotated tag named old is used in the example, and will be renamed to new.

Step 1: Get existing tag information

First, we need to get the information for the existing tag. This can be achieved using for-each-ref:

Command:

git for-each-ref refs/tags --format="\
Tag name: %(refname:short)
Tag commit: %(objectname:short)
Tagger date: %(taggerdate)
Tagger name: %(taggername)
Tagger email: %(taggeremail)
Tagged commit: %(*objectname:short)
Tag message: %(contents)"

Output:

Tag commit: 88a6169
Tagger date: Mon Dec 14 12:44:52 2020 -0600
Tagger name: John Doe
Tagger email: <[email protected]>
Tagged commit: cda5b4d
Tag name: old
Tag message: Initial tag

Body line 1.
Body line 2.
Body line 3.

Step 2: Create a duplicate tag locally

A duplicate tag with the new name can be created using the info gathered in step 1 from the existing tag.

The commit ID & commit message can be passed directly to git tag.

The tagger information (name, email, and date) can be set using the git environment variables GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL, GIT_COMMITTER_DATE. The date usage in this context is described in the On Backdating Tags documentation for git tag; the other two I figured out through experimentation.

GIT_COMMITTER_NAME="John Doe" GIT_COMMITTER_EMAIL="[email protected]" \
GIT_COMMITTER_DATE="Mon Dec 14 12:44:52 2020 -0600" git tag new cda5b4d -a -m "Initial tag

Body line 1.
Body line 2.
Body line 3."

A side-by-side comparison of the two tags shows they're identical in all the ways that matter. The only thing that's differing here is the commit reference of the tag itself, which is expected since they're two different tags.

Command:

git for-each-ref refs/tags --format="\
Tag commit: %(objectname:short)
Tagger date: %(taggerdate)
Tagger name: %(taggername)
Tagger email: %(taggeremail)
Tagged commit: %(*objectname:short)
Tag name: %(refname:short)
Tag message: %(contents)"

Output:

Tag commit: 580f817
Tagger date: Mon Dec 14 12:44:52 2020 -0600
Tagger name: John Doe
Tagger email: <[email protected]>
Tagged commit: cda5b4d
Tag name: new
Tag message: Initial tag

Body line 1.
Body line 2.
Body line 3.

Tag commit: 30ddd25
Tagger date: Mon Dec 14 12:44:52 2020 -0600
Tagger name: John Doe
Tagger email: <[email protected]>
Tagged commit: cda5b4d
Tag name: old
Tag message: Initial tag

Body line 1.
Body line 2.
Body line 3.

As a single command, including retrieving the current tag data:

SOURCE_TAG=old NEW_TAG=new; deref() { git for-each-ref "refs/tags/$SOURCE_TAG" --format="%($1)" ; }; GIT_COMMITTER_NAME="$(deref taggername)" GIT_COMMITTER_EMAIL="$(deref taggeremail)" GIT_COMMITTER_DATE="$(deref taggerdate)" git tag "$NEW_TAG" "$(deref "*objectname")" -a -m "$(deref contents)"

Step 3: Delete the existing tag locally

Next, the existing tag should be deleted locally. This step can be skipped if you wish to keep the old tag along with the new one (i.e. duplicate the tag rather than rename it).

git tag -d old

Step 4: Push changes to remote repository

Assuming you're working from a remote repository, the changes can now be pushed using git push:

git push origin new :old

This pushes the new tag, and deletes the old tag.

As of Gradle 4.9 Application plugin understands --args option, so passing the arguments is as simple as:

build.gradle

plugins {
    id 'application'
}

mainClassName = "my.App"

src/main/java/my/App.java

public class App {
    public static void main(String[] args) {
        System.out.println(args);
    }
}

bash

./gradlew run --args='This string will be passed into my.App#main arguments'

or in Windows, use double quotes:

gradlew run --args="This string will be passed into my.App#main arguments"

I actually wrote a package called cherrypicker recently to deal with this exact sort of thing since I had to do it so often!

I think the following code would give you exactly what you're after:

from cherrypicker import CherryPicker

dct = {
    'a': 1,
    'c': {
        'a': 2,
        'b': {
            'x': 5,
            'y' : 10
        }
    },
    'd': [1, 2, 3]
}

picker = CherryPicker(dct)
picker.flatten().get()

You can install the package with:

pip install cherrypicker

...and there's more docs and guidance at https://cherrypicker.readthedocs.io.

Other methods may be faster, but the priority of this package is to make such tasks easy. If you do have a large list of objects to flatten though, you can also tell CherryPicker to use parallel processing to speed things up.

So there are few places where terminal looks for commands. This places are stored in your $PATH variable. Think of it as a global variable where terminal iterates over to look up for any command. This are usually binaries look how /bin folder is usually referenced.

/bin folder has lots of executable files inside it. Turns out this are command. This different folder locations are stored inside one Global variable i.e. $PATH separated by :

Now usually programs upon installation takes care of updating PATH & telling your terminal that hey i can be all commands inside my bin folder.

Turns out MySql doesn't do it upon install so we manually have to do it.

We do it by following command,

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

If you break it down, export is self explanatory. Think of it as an assignment. So export a variable PATH with value old $PATH concat with new bin i.e. /usr/local/mysql/bin

This way after executing it all the commands inside /usr/local/mysql/bin are available to us.

There is a small catch here. Think of one terminal window as one instance of program and maybe something like $PATH is class variable ( maybe ). Note this is pure assumption. So upon close we lose the new assignment. And if we reopen terminal we won't have access to our command again because last when we exported, it was stored in primary memory which is volatile.

Now we need to have our mysql binaries exported every-time we use terminal. So we have to persist concat in our path.

You might be aware that our terminal using something called dotfiles to load configuration on terminal initialisation. I like to think of it's as sets of thing passed to constructer every-time a new instance of terminal is created ( Again an assumption but close to what it might be doing ). So yes by now you get the point what we are going todo.

.bash_profile is one of the primary known dotfile.

So in following command,

echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile

What we are doing is saving result of echo i.e. output string to ~/.bash_profile

So now as we noted above every-time we open terminal or instance of terminal our dotfiles are loaded. So .bash_profile is loaded respectively and export that we appended above is run & thus a our global $PATH gets updated and we get all the commands inside /usr/local/mysql/bin.

P.s.

if you are not running first command export directly but just running second in order to persist it? Than for current running instance of terminal you have to,

source ~/.bash_profile

This tells our terminal to reload that particular file.

Date is a simpler class and is mainly there for backward compatibility reasons. If you need to set particular dates or do date arithmetic, use a Calendar. Calendars also handle localization. The previous date manipulation functions of Date have since been deprecated.

Personally I tend to use either time in milliseconds as a long (or Long, as appropriate) or Calendar when there is a choice.

Both Date and Calendar are mutable, which tends to present issues when using either in an API.

I resolved this same problem in python using flask and with this library. flask_cors

Reference: https://flask-cors.readthedocs.io/en/latest/

Instead of using a margin, could you use a border? You should do this with <div>, anyway.

Something like this?

http://jsfiddle.net/GBTHv/

Use this:

var table = $(selector).dataTables();
table.api().draw(false);

or

var table = $(selector).DataTables();
table.draw(false);

Short answer: Fabulous.

Long answer: Something like....

static SomeSingleton *instance = NULL;

@implementation SomeSingleton

+ (id) instance {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        if (instance == NULL){
            instance = [[super allocWithZone:NULL] init];
        }
    });
    return instance;
}

+ (id) allocWithZone:(NSZone *)paramZone {
    return [[self instance] retain];
}

- (id) copyWithZone:(NSZone *)paramZone {
    return self;
}

- (id) autorelease {
    return self;
}

- (NSUInteger) retainCount {
    return NSUIntegerMax;
}

- (id) retain {
    return self;
}

@end

Be sure to read the dispatch/once.h header to understand what's going on. In this case the header comments are more applicable than the docs or man page.

One quick solution that came to mind :-

<input type="checkbox" id="markitem" name="markitem" value="1" onchange="GetMarkedItems(1)">
<label for="markitem" style="position:absolute; top:1px; left:165px;">&nbsp</label>
<!-- Fire the below javascript everytime the page reloads -->
<script type=text/javascript>
  document.getElementById("markitem").checked = false;
</script>
<!-- Tested on Latest FF, Chrome, Opera and IE. -->

I'm aware that this question is a bit old, but I consider that my small update could help other programmers.

I didn't want to modify WhoIsRich's answer because it's really great, but I adapted it to fulfill my needs:

1. If the Automatically Detect Settings is checked then uncheck it.

2. If the Automatically Detect Settings is unchecked then check it.

   On Error Resume Next
   
   Set oReg   = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")
   sKeyPath   = "Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections"
   sValueName = "DefaultConnectionSettings"
   
   ' Get registry value where each byte is a different setting.
   oReg.GetBinaryValue &H80000001, sKeyPath, sValueName, bValue
   
   ' Check byte to see if detect is currently on.
   If (bValue(8) And 8) = 8 Then
       ' To change the value to Off.
       bValue(8) = bValue(8) And Not 8
   ' Check byte to see if detect is currently off.
   ElseIf (bValue(8) And 8) = 0 Then
       ' To change the value to On.
       bValue(8) = bValue(8) Or 8
   End If
   
   'Write back settings value
   oReg.SetBinaryValue &H80000001, sKeyPath, sValueName, bValue
   
   Set oReg = Nothing
   

Finally, you only need to save it in a .VBS file (VBScript) and run it.

You can also use this code to get LayoutInflater:

LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)

It sounds to me as if you actually mean "linux guests" and not "linux hosts".

But in any case, I suspect you did not install the VMWare Tools: doubleclick on that icon on the Desktop that can be seen on your screenshot. It will install some drivers that communicate with VMWare that, among other things, allow to adjust the screen resolution dynamically.

When the installation process is finished, you'll most likely have to reboot the VM.

This is certainly something that has a lot of traps. I was working with Paolo Bergantino's answer, and realising that even that has some limitations. I found working with string representations of dates a good place to quickly find some of the main problems. Start with an input string like this: '12-2-2019 5:1:48.670'

and set up Paolo's function like this:

function count(re, str) {
    if (typeof re !== "string") {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    var cre = new RegExp(re, 'g');
    return ((str || '').match(cre) || []).length;
}

I wanted the regular expression to be passed in, so that the function is more reusable, secondly, I wanted the parameter to be a string, so that the client doesn't have to make the regex, but simply match on the string, like a standard string utility class method.

Now, here you can see that I'm dealing with issues with the input. With the following:

if (typeof re !== "string") {
    return 0;
}

I am ensuring that the input isn't anything like the literal 0, false, undefined, or null, none of which are strings. Since these literals are not in the input string, there should be no matches, but it should match '0', which is a string.

With the following:

re = (re === '.') ? ('\\' + re) : re;

I am dealing with the fact that the RegExp constructor will (I think, wrongly) interpret the string '.' as the all character matcher \.\

Finally, because I am using the RegExp constructor, I need to give it the global 'g' flag so that it counts all matches, not just the first one, similar to the suggestions in other posts.

I realise that this is an extremely late answer, but it might be helpful to someone stumbling along here. BTW here's the TypeScript version:

function count(re: string, str: string): number {
    if (typeof re !== 'string') {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    const cre = new RegExp(re, 'g');    
    return ((str || '').match(cre) || []).length;
}

Actually, you have to use the anchor # to play with this. If you reverse engineer the Gmail url system, you'll find

https://mail.google.com/mail/u/0/#inbox
https://mail.google.com/mail/u/0/#inbox?compose=new

Everything after # is the part your want to load in your page, then you just have to chose where to load it.

By the way, using document.location by adding a #something won't refresh your page.

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

1. Run WampServer: Apache->service->test port 80.

2. Find out what application which occupies the port 80(e.g. skype)

3. Shut down and restarts WampServer.

@Zugwait's answer is correct. req.param() is deprecated. You should use req.params, req.query or req.body.

But just to make it clearer:

req.params will be populated with only the route values. That is, if you have a route like /users/:id, you can access the id either in req.params.id or req.params['id'].

req.query and req.body will be populated with all params, regardless of whether or not they are in the route. Of course, parameters in the query string will be available in req.query and parameters in a post body will be available in req.body.

So, answering your questions, as color is not in the route, you should be able to get it using req.query.color or req.query['color'].

Tasks have first class support for cancellation via cancellation tokens. Create your tasks with cancellation tokens, and cancel the tasks via these explicitly.

Have a look at GROUP_CONCAT if your MySQL version (4.1) supports it. See the documentation for more details.

It would look something like:

  SELECT GROUP_CONCAT(hobbies SEPARATOR ', ') 
  FROM peoples_hobbies 
  WHERE person_id = 5 
  GROUP BY 'all';

Most of solutions use static width here. But it can be sometimes wrong for some reasons.

Example: I had table with many columns. Most of them are narrow (static width). But the main column should be as wide as possible (depends on screen size).

HTML:

<table style="width: 100%">
  <tr>
    <td style="width: 60px;">narrow</td>
    <td>
      <span class="cutwrap" data-cutwrap="dynamic column can have really long text which can be wrapped on two rows, but we just need not wrapped texts using as much space as possible">
        dynamic column can have really long text which can be wrapped on two rows
        but we just need not wrapped texts using as much space as possible
      </span>
    </td>
  </tr>
</table>

CSS:

.cutwrap {
  position: relative;
  overflow: hidden;
  display: block;
  width: 100%;
  height: 18px;
  white-space: normal;
  color: transparent !important;
}
.cutwrap::selection {
  color: transparent !important;
}
.cutwrap:before {
  content: attr(data-cutwrap);
  position: absolute;
  left: 0;
  right: 0;
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
  color: #333;
}
/* different styles for links */
a.cutwrap:before {
  text-decoration: underline;
  color: #05c;
}

If you're on a linux system, once you have the file descriptor you can get a lot of information about the file using fstat()

http://linux.die.net/man/2/stat

so you might have

#include  <unistd.h> 
void main()
{
    struct stat stat;
    int fd;
    //get file descriptor
    fstat(fd, &stat);
    //the size of the file is now in stat.st_size
}

This avoids seeking to the beginning and end of the file.

Here is the simplest solution to your query

$date=date_create("2013-03-15"); // or your date string
date_add($date,date_interval_create_from_date_string("40 days"));// add number of days 
echo date_format($date,"Y-m-d"); //set date format of the result

Ok I will suppose a general use, first you have to download apache commons, there you will find an utility class named IOUtils which has a method named copy();

Now the solution is: get the input stream of your CLOB object using getAsciiStream() and pass it to the copy() method.

InputStream in = clobObject.getAsciiStream();
StringWriter w = new StringWriter();
IOUtils.copy(in, w);
String clobAsString = w.toString();

From Ruby API:

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

When you use require to load a file, you are usually accessing functionality that has been properly installed, and made accessible, in your system. require does not offer a good solution for loading files within the project’s code. This may be useful during a development phase, for accessing test data, or even for accessing files that are "locked" away inside a project, not intended for outside use.

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1" 

Since neither "test" nor "test/data" are likely to be in Ruby’s library path (and for good reason), a normal require won’t find them. require_relative is a good solution for this particular problem.

You may include or omit the extension (.rb or .so) of the file you are loading.

path must respond to to_str.

You can find the documentation at http://extensions.rubyforge.org/rdoc/classes/Kernel.html

Also you can position the other window before withdrawing it so that you position your message

from tkinter import *
import tkinter.messagebox

window = Tk()
window.wm_withdraw()

# message at x:200,y:200
window.geometry("1x1+200+200")  # remember its.geometry("WidthxHeight(+or-)X(+or-)Y")
tkinter.messagebox.showerror(title="error", message="Error Message", parent=window)

# center screen message
window.geometry(f"1x1+{round(window.winfo_screenwidth() / 2)}+{round(window.winfo_screenheight() / 2)}")
tkinter.messagebox.showinfo(title="Greetings", message="Hello World!")

Please Note: This is Lewis Cowles' answer just Python 3ified, since tkinter has changed since python 2. If you want your code to be backwords compadible do something like this:

try:
    import tkinter
    import tkinter.messagebox
except ModuleNotFoundError:
    import Tkinter as tkinter
    import tkMessageBox as tkinter.messagebox

scroll at particular position
and this helped me alot. by click listener you can get the position in your adapter

layoutmanager.scrollToPosition(int position);

Modern solution

Flexbox was created for exactly these kind of problems:

#container {_x000D_
    height: 150px;/*Only for the demo.*/_x000D_
    background-color:green;/*Only for the demo.*/_x000D_
    display: flex;_x000D_
    justify-content: center;_x000D_
    align-items: flex-end;_x000D_
}

<div id="container">_x000D_
    <span>Text align to center bottom.</span>_x000D_
</div>

Old school solution

If you don't want to mess with table displays, then you can create a <div> inside a relatively positioned parent container, place it to the bottom with absolute positioning, then make it 100% wide, so you can text-align it to the center:

#container {_x000D_
    height: 150px;/*Only for the demo.*/_x000D_
    background-color:green;/*Only for the demo.*/_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
#text {_x000D_
    position: absolute;_x000D_
    bottom: 0;_x000D_
    width: 100%;_x000D_
    text-align: center;_x000D_
}

<div id="container">_x000D_
    <span id="text">Text align to center bottom.</span>_x000D_
</div>

In my case I was getting the grey background and it turned out to be inclusion of a zoom value in the map options. Yup, makes no sense.

In case of not having the yaml file:

kubectl get pod PODNAME -n NAMESPACE -o yaml | kubectl replace --force -f -

What you really need is a full absolute classPath for the file. So instead of guessing it, try to find out the ROOT and then move the file to a better location base one <.war> file structures...

URL test1 = getClass().getResource("/");
URL test2 = getClass().getClassLoader().getResource("/");            
URL test3 = getClass().getClassLoader().getResource("../");

logger.info(test1.getPath()); 
logger.info(test2.getPath());
logger.info(test3.getPath());

I found that sometimes JavaScript doesn't allow me to click the checkbox because was working with the element by onchange event.

And that sentence helps me to allow the problem:

driver.findElement(By.xpath(".//*[@id='theID']")).sendKeys(Keys.SPACE);

According to this document, add the following code to onCreate

getWindow().getDecorView().setSystemUiVisibility(SYSTEM_UI_FLAG_IMMERSIVE_STICKY |
        SYSTEM_UI_FLAG_FULLSCREEN | SYSTEM_UI_FLAG_HIDE_NAVIGATION   | 
        SYSTEM_UI_FLAG_LAYOUT_STABLE | SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

an EXE file is created as long as you build the project. you can usually find this on the debug folder of you project.

C:\Users\username\Documents\Visual Studio 2012\Projects\ProjectName\bin\Debug

this part :

"Your new price is: $"(float(price)

asks python to call this string:

"Your new price is: $"

just like you would a function: function( some_args) which will ALWAYS trigger the error:

TypeError: 'str' object is not callable

I also got the same error. I've referred to the below mentioned link and ran this commands

gpg --import fails with no valid OpenPGP data found

gpg --import KEYS
sudo apt-get update

It worked.

I'm using Ubuntu version 12.04

To start with git log -1 --pretty='%s'

But the below one covers all the cases,

git log --pretty='format:%Creset%s' --no-merges -1

• No unwanted white spaces
• Discards merge commits
• No commit id, date, Displays only the messages.

Paste & see for yourself

These solutions are working in case when target database is blank. In case when both databases already have some data you need something more complicated http://byalexblog.net/merge-sql-databases

I have a script written in PHP similar to that of @neverpanic that automatically downloads both the CSS and fonts (both hinted and unhinted) from Google. It then serves the correct CSS and fonts from your own server based on the User Agent. It keeps its own cache, so fonts and CSS of a User Agent will only be downloaded once.

It's in a premature stage, but it can be found here: DaAwesomeP / php-offline-fonts

These solutions has bug. When use solutions at below, windows has delay at closing.

Menu.setApplicationMenu(null),
&&
const updateErrorWindow = new BrowserWindow({autoHideMenuBar: true});

I used solution at below. This is better for now.

const window= new BrowserWindow({...});
window.setMenuBarVisibility(false);

Actually speaking, when I tried this, it worked only when I set the action and method value for the form. Funny how it works though!

you could deserialize your json string into a dictionary and then add new properties then serialize it.

 var jsonString = @"{}";

        var jsonDoc = JsonSerializer.Deserialize<Dictionary<string, object>>(jsonString);

        jsonDoc.Add("Name", "Khurshid Ali");

        Console.WriteLine(JsonSerializer.Serialize(jsonDoc));

There is one thing that may be optimized in the suggested solutions. Having many calls to Replace() makes the code to do multiple passes over the same string. With very long strings the solutions may be slow because of CPU cache capacity misses. May be one should consider replacing multiple strings in a single pass.

You can use the code below to solve the problem or download demo here

Create two functions to handle each.

First, the canvas is drawn and the images are drawn on top of each other from point (0,0)

On button click

public void buttonMerge(View view) {

        Bitmap bigImage = BitmapFactory.decodeResource(getResources(), R.drawable.img1);
        Bitmap smallImage = BitmapFactory.decodeResource(getResources(), R.drawable.img2);
        Bitmap mergedImages = createSingleImageFromMultipleImages(bigImage, smallImage);

        img.setImageBitmap(mergedImages);
    }

Function to create an overlay.

private Bitmap createSingleImageFromMultipleImages(Bitmap firstImage, Bitmap secondImage){

    Bitmap result = Bitmap.createBitmap(firstImage.getWidth(), firstImage.getHeight(), firstImage.getConfig());
    Canvas canvas = new Canvas(result);
    canvas.drawBitmap(firstImage, 0f, 0f, null);
    canvas.drawBitmap(secondImage, 10, 10, null);
    return result;

You can check if the array is empty by retrieving total elements count using JScript's VBArray() object (works with arrays of variant type, single or multidimensional):

Sub Test()

    Dim a() As Variant
    Dim b As Variant
    Dim c As Long

    ' Uninitialized array of variant
    ' MsgBox UBound(a) ' gives 'Subscript out of range' error
    MsgBox GetElementsCount(a) ' 0

    ' Variant containing an empty array
    b = Array()
    MsgBox GetElementsCount(b) ' 0

    ' Any other types, eg Long or not Variant type arrays
    MsgBox GetElementsCount(c) ' -1

End Sub

Function GetElementsCount(aSample) As Long

    Static oHtmlfile As Object ' instantiate once

    If oHtmlfile Is Nothing Then
        Set oHtmlfile = CreateObject("htmlfile")
        oHtmlfile.parentWindow.execScript ("function arrlength(arr) {try {return (new VBArray(arr)).toArray().length} catch(e) {return -1}}"), "jscript"
    End If
    GetElementsCount = oHtmlfile.parentWindow.arrlength(aSample)

End Function

For me it takes about 0.3 mksec for each element + 15 msec initialization, so the array of 10M elements takes about 3 sec. The same functionality could be implemented via ScriptControl ActiveX (it is not available in 64-bit MS Office versions, so you can use workaround like this).

New answer:

In HTML5 you can add the multiple attribute to select more than 1 file.

<input type="file" name="filefield" multiple="multiple">

Old answer:

You can only select 1 file per <input type="file" />. If you want to send multiple files you will have to use multiple input tags or use Flash or Silverlight.

Try this:

def word(string, num)
    string = 'Smith'
    string[0..(num-1)]
end

I think you missed a equal sign at:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);  

Change to:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null); 

Something like this? Takes advantage of short-circuit evaluation. If the file does not exist, the whole conditional cannot be true, so python will not bother evaluation the second part.

os.path.exists("gogogo.php") and os.remove("gogogo.php")

use

SELECT COL_LENGTH('tablename', 'colname')

None of other solution worked for me.

You might want to take a look at a similar question posted on Stack Overflow. It uses the .apply() method to accomplish this.

There's a lot of misunderstanding being displayed here. Unicode isn't an encoding, but the Unicode standard is devoted primarily to encoding anyway.

ISO 10646 is the international character set you (probably) care about. It defines a mapping between a set of named characters (e.g., "Latin Capital Letter A" or "Greek small letter alpha") and a set of code points (a number assigned to each -- for example, 61 hexadecimal and 3B1 hexadecimal for those two respectively; for Unicode code points, the standard notation would be U+0061 and U+03B1).

At one time, Unicode defined its own character set, more or less as a competitor to ISO 10646. That was a 16-bit character set, but it was not UTF-16; it was known as UCS-2. It included a rather controversial technique to try to keep the number of necessary characters to a minimum (Han Unification -- basically treating Chinese, Japanese and Korean characters that were quite a bit alike as being the same character).

Since then, the Unicode consortium has tacitly admitted that that wasn't going to work, and now concentrate primarily on ways to encode the ISO 10646 character set. The primary methods are UTF-8, UTF-16 and UCS-4 (aka UTF-32). Those (except for UTF-8) also have LE (little endian) and BE (big-endian) variants.

By itself, "Unicode" could refer to almost any of the above (though we can probably eliminate the others that it shows explicitly, such as UTF-8). Unqualified use of "Unicode" probably happens the most often on Windows, where it will almost certainly refer to UTF-16. Early versions of Windows NT adopted Unicode when UCS-2 was current. After UCS-2 was declared obsolete (around Win2k, if memory serves), they switched to UTF-16, which is the most similar to UCS-2 (in fact, it's identical for characters in the "basic multilingual plane", which covers a lot, including all the characters for most Western European languages).

If your Service is started by your app then actually your service is running on main process. so when app is killed service will also be stopped. So what you can do is, send broadcast from onTaskRemoved method of your service as follows:

 Intent intent = new Intent("com.android.ServiceStopped");
 sendBroadcast(intent);

and have an broadcast receiver which will again start a service. I have tried it. service restarts from all type of kills.

Think of it this way:

An iterator is just a fancy sounding term for an object that has a next() method. So a yield-ed function ends up being something like this:

Original version:

def some_function():
    for i in xrange(4):
        yield i

for i in some_function():
    print i

This is basically what the Python interpreter does with the above code:

class it:
    def __init__(self):
        # Start at -1 so that we get 0 when we add 1 below.
        self.count = -1

    # The __iter__ method will be called once by the 'for' loop.
    # The rest of the magic happens on the object returned by this method.
    # In this case it is the object itself.
    def __iter__(self):
        return self

    # The next method will be called repeatedly by the 'for' loop
    # until it raises StopIteration.
    def next(self):
        self.count += 1
        if self.count < 4:
            return self.count
        else:
            # A StopIteration exception is raised
            # to signal that the iterator is done.
            # This is caught implicitly by the 'for' loop.
            raise StopIteration

def some_func():
    return it()

for i in some_func():
    print i

For more insight as to what's happening behind the scenes, the for loop can be rewritten to this:

iterator = some_func()
try:
    while 1:
        print iterator.next()
except StopIteration:
    pass

Does that make more sense or just confuse you more? :)

I should note that this is an oversimplification for illustrative purposes. :)

Below I use a temp table to get the minimum of several dates. The first temp table queries several joined tables to get various dates (as well as other values for the query), the second temp table then gets the various columns and the minimum date using as many passes as there are date columns.

This is essentially like the union query, the same number of passes are required, but may be more efficient (based on experience, but would need testing). Efficiency wasn't an issue in this case (8,000 records). One could index etc.

from #temp1 t1 join #temp2 t2 on t1.recordid = t2.recordid
order by t1.recordid

You can combine your counts like you were doing before, but then you could sum them all up a number of ways, one of which is shown below:

SELECT SUM(A) 
FROM
(
    SELECT 1 AS A
    UNION ALL 
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
) AS B

You can use convert from hablar to change a column of the data frame quickly.

library(tidyverse)
library(hablar)

x <- tibble(var = c(1.34, 4.45, 6.98))

x %>% 
  convert(int(var))

gives you:

# A tibble: 3 x 1
    var
  <int>
1     1
2     4
3     6

if you are using mac, proceed with following steps:

1. Move to following directory:

   /sts-bundle/STS.app/Contents/Eclipse
   

2. Add the java home explicitly in STS.ini file:

   -vm
   /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bin
   -vmargs
   

Make sure not to add all the statements in single line

There is also an another actively developed alternative - JSCS — JavaScript Code Style:

JSCS is a code style linter for programmatically enforcing your style guide. You can configure JSCS for your project in detail using over 150 validation rules, including presets from popular style guides like jQuery, Airbnb, Google, and more.

It comes with multiple presets that you can choose from by simply specifying the preset in the .jscsrc configuration file and customize it - override, enable or disable any rules:

{
    "preset": "jquery",
    "requireCurlyBraces": null
}

There are also plugins and extensions built for popular editors.

From your above needs, you will need to use both Python (to export pandas data frame) and VBA (to delete existing worksheet content and copy/paste external data).

With Python: use the to_csv or to_excel methods. I recommend the to_csv method which performs better with larger datasets.

# DF TO EXCEL
from pandas import ExcelWriter

writer = ExcelWriter('PythonExport.xlsx')
yourdf.to_excel(writer,'Sheet5')
writer.save()

# DF TO CSV
yourdf.to_csv('PythonExport.csv', sep=',')

With VBA: copy and paste source to destination ranges.

Fortunately, in VBA you can call Python scripts using Shell (assuming your OS is Windows).

Sub DataFrameImport()
  'RUN PYTHON TO EXPORT DATA FRAME
  Shell "C:\pathTo\python.exe fullpathOfPythonScript.py", vbNormalFocus

  'CLEAR EXISTING CONTENT
  ThisWorkbook.Worksheets(5).Cells.Clear

  'COPY AND PASTE TO WORKBOOK
  Workbooks("PythonExport").Worksheets(1).Cells.Copy
  ThisWorkbook.Worksheets(5).Range("A1").Select
  ThisWorkbook.Worksheets(5).Paste
End Sub

Alternatively, you can do vice versa: run a macro (ClearExistingContent) with Python. Be sure your Excel file is a macro-enabled (.xlsm) one with a saved macro to delete Sheet 5 content only. Note: macros cannot be saved with csv files.

import os
import win32com.client
from pandas import ExcelWriter

if os.path.exists("C:\Full Location\To\excelsheet.xlsm"):
  xlApp=win32com.client.Dispatch("Excel.Application")
  wb = xlApp.Workbooks.Open(Filename="C:\Full Location\To\excelsheet.xlsm")

  # MACRO TO CLEAR SHEET 5 CONTENT
  xlApp.Run("ClearExistingContent")
  wb.Save() 
  xlApp.Quit()
  del xl

  # WRITE IN DATA FRAME TO SHEET 5
  writer = ExcelWriter('C:\Full Location\To\excelsheet.xlsm')
  yourdf.to_excel(writer,'Sheet5')
  writer.save() 

You can use sheet.addMergedRegion(rowFrom,rowTo,colFrom,colTo);

example sheet.addMergedRegion(new CellRangeAddress(1,1,1,4)); will merge from B2 to E2. Remember it is zero based indexing (ex. POI version 3.12).

The SDK is only available on OS X, forcing you to use a mac. If you don't want to purchase a mac you can either run OS X on a virtual machine on your windows box, or you can install OS X on your PC.

In my experience the virtual machine solution is unusably slow (on a core2 duo laptop with 2G ram). If you feel like trying it search for the torrent. It's probably not worthwhile.

The other option is to install OS X on your PC, commonly referred to as a hackintosh. Hackintoshes work quite well - my friend just sold his mac because his Dell quad core hackintosh was actually much faster than the apple hardware (and cost about 1/3). You can find lots of articles on how to do this; here's one on how to install on a Dell Inspirion 1525 laptop: hackbook pro tutorial

Of course both of these options are likely counter to some licensing scheme, so proceed at your own risk.
