You're all concentrating on the word 'get' in the question. Try the 'elements' property of any form which is a collection that you can iterate through i.e. you write your own 'get' function.

Example:

function getFormElelemets(formName){
  var elements = document.forms[formName].elements;
  for (i=0; i<elements.length; i++){
    some code...
  }
}

Hope that helps.

You can do it by using Arrays.sort and Recursion. The same wine but in a different bottle....

import java.util.Arrays;

public class ArrayTest {
public static int mainCount=0;

public static void main(String[] args) {
    String prevItem = "";
    String[] array = {"name1","name1","name2","name2", "name2"};
    Arrays.sort(array);

    for(String item:array){
        if(! prevItem.equals(item)){
            mainCount = 0;
            countArray(array, 0, item);
            prevItem = item;
        }
    }
}

private static void countArray(String[] arr, int currentPos, String item) {
    if(currentPos == arr.length){
        System.out.println(item + " " +  mainCount);
        return;
    }
    else{
        if(arr[currentPos].toString().equals(item)){
            mainCount += 1;
        }
        countArray(arr, currentPos+1, item);
    }
  }
}

In ES6 this could be accomplished with a reduce() call in O(n) complexity as opposed to solutions using sort() which is O(nlogn):

const getLongestText = (arr) => arr.reduce(_x000D_
  (savedText, text) => (text.length > savedText.length ? text : savedText),_x000D_
  '',_x000D_
);_x000D_
_x000D_
console.log(getLongestText(['word', 'even-longer-word', 'long-word']))

I think you have to define the timestamp column like this

CREATE TABLE t1 
(
    ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

See here

just for fun...

$array_a = array('0'=>'foo', '1'=>'bar');
$array_b = array('foo'=>'0', 'bar'=>'1');

$array_c = array_merge($array_a,$array_b);

$i = 0; $j = 0;
foreach ($array_c as $key => $value) {
    if (is_numeric($key)) {$array_d[$i] = $value; $i++;}
    if (is_numeric($value)) {$array_e[$j] = $key; $j++;}
}

print_r($array_d);
print_r($array_e);

I use standard HTML tags, like

<!---
your comment goes here
and here
-->

Note the triple dash. The advantage is that it works with pandoc when generating TeX or HTML output. More information is available on the pandoc-discuss group.

Quick and dirty, and store it in a variable:

USER=somebody
USER_HOME="$(echo -n $(bash -c "cd ~${USER} && pwd"))"

CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.

=Sumifs(B:B,A:A,">=1/1/2013",A:A,"<=1/31/2013")

The beauty of this formula is you can add more data to columns A and B and it will just recalculate.

My solution, using if..else statement. It is always a good practice if you want to avoid unnecessary frustrations, to check that your variable exists and is set. Otherwise, provide a backup image in case; You can also specify multiple style properties, like background-position: center, etc.

<div [ngStyle]="{'background-image': this.photo ? 'url(' + this.photo + ')' : 'https://placehold.it/70x70', 'background-position': 'center' }"></div>

You can use the _.deburr() method from the Lodash library.

It's available as a stand-alone NPM package lodash.deburr, or as part of the lodash package.

const myStringWithAccent = 'Mon café est plein de caféïne';
const myStringWithoutAccent = _.deburr( myStringWithAccent, );

The result will be : "Mon cafe est plein de cafeine"

String dt = Date.Now.ToString("yyyy-MM-dd");

Now you got this for dt, 2010-09-09

To get the Color from Hex.

using System.Windows.Media;

Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");

and then set the foreground

textBlock.Foreground = new System.Windows.Media.SolidColorBrush(color); 

I came across this question, and the answers here didn't work for me; i couldn't figure out why i can't login and got the above error.

It turns out that postgresql saves usernames lowercase, but during authentication it uses both upper- and lowercase.

CREATE USER myNewUser WITH PASSWORD 'passWord';

will create a user with the username 'mynewuser' and password 'passWord'.

This means you have to authenticate with 'mynewuser', and not with 'myNewUser'. For a newbie in pgsql like me, this was confusing. I hope it helps others who run into this problem.

The solution is to run an NTP client , just run the command as below

#ntpdate 172.16.12.100

172.16.12.100 is the ntp server

You need to use WebConfigurationManager.OpenWebConfiguration(): For Example:

Dim myConfiguration As Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")
myConfiguration.ConnectionStrings.ConnectionStrings("myDatabaseName").ConnectionString = txtConnectionString.Text
myConfiguration.AppSettings.Settings.Item("myKey").Value = txtmyKey.Text
myConfiguration.Save()

I think you might also need to set AllowLocation in machine.config. This is a boolean value that indicates whether individual pages can be configured using the element. If the "allowLocation" is false, it cannot be configured in individual elements.

Finally, it makes a difference if you run your application in IIS and run your test sample from Visual Studio. The ASP.NET process identity is the IIS account, ASPNET or NETWORK SERVICES (depending on IIS version).

Might need to grant ASPNET or NETWORK SERVICES Modify access on the folder where web.config resides.

Try this one:

function show_sub(cat) {
    var parent = cat,
    sub = parent.getElementsByClassName('sub');
    if (sub[0].style.display == 'inline'){
        sub[0].style.display = 'none';
    }
    else {
        sub[0].style.display = 'inline';
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this);
};?

and use this for IE6 & 7

if (typeof document.getElementsByClassName!='function') {
    document.getElementsByClassName = function() {
        var elms = document.getElementsByTagName('*');
        var ei = new Array();
        for (i=0;i<elms.length;i++) {
            if (elms[i].getAttribute('class')) {
               ecl = elms[i].getAttribute('class').split(' ');
                for (j=0;j<ecl.length;j++) {
                    if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
                        ei.push(elms[i]);
                    }
                }
            } else if (elms[i].className) {
                ecl = elms[i].className.split(' ');
                for (j=0;j<ecl.length;j++) {
                    if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
                        ei.push(elms[i]);
                    }
                }
            }
        }
        return ei;
    }
}

In the your first journey in spring boot project I recommend you to start with Spring Starter Try this link here.

It will auto generate the project structure for you like this.application.perperties it will be under /resources.

application.properties important change,

server.port = Your PORT(XXXX) by default=8080
server.servlet.context-path=/api (SpringBoot version 2.x.)
server.contextPath-path=/api (SpringBoot version < 2.x.)

Any way you can use application.yml in case you don't want to make redundancy properties setting.

Example
application.yml

server:
   port: 8080 
   contextPath: /api

application.properties

server.port = 8080
server.contextPath = /api

Using table-layout: fixed as a property for table and width: calc(100%/3); for td (assuming there are 3 td's). With these two properties set, the table cells will be equal in size.

Refer to the demo.

With .split:

var arr = str.split( /(?<=^(?:.{3})+)(?!$)/ )  // [ 'abc', 'def', 'ghi', 'jkl' ]

and .replace will be:

var replaced = str.replace( /(?<=^(.{3})+)(?!$)/g, ' || ' )  // 'abc || def || ghi || jkl'

/(?!$)/ is to to stop before end/$/, without is:

var arr      = str.split( /(?<=^(?:.{3})+)/ )        // [ 'abc', 'def', 'ghi', 'jkl' ]     // I don't know why is not [ 'abc', 'def', 'ghi', 'jkl' , '' ], comment?
var replaced = str.replace( /(?<=^(.{3})+)/g, ' || ')  // 'abc || def || ghi || jkl || '

ignoring group /(?:...)/ is no need in .replace but in .split is adding groups to arr:

var arr = str.split( /(?<=^(.{3})+)(?!$)/ )  // [ 'abc', 'abc', 'def', 'abc', 'ghi', 'abc', 'jkl' ]

If you are using react-redux for your application and if you want to show data which is in the redux store, you can set "checked" option as below.

<label>Male</label>

 <input
   type="radio"
   name="gender"
   defaultChecked={this.props.gender == "0"}
 />



 <label>Female</label>
 <input
   type="radio"
   name="gender"
   defaultChecked={this.props.gender == "1"}
 />

The OSHI project provides platform-independent hardware utilities.

Maven dependency:

<dependency>
    <groupId>com.github.oshi</groupId>
    <artifactId>oshi-core</artifactId>
    <version>LATEST</version>
</dependency>

For instance, you could use something like the following code to identify a machine uniquely:

import oshi.SystemInfo;
import oshi.hardware.CentralProcessor;
import oshi.hardware.ComputerSystem;
import oshi.hardware.HardwareAbstractionLayer;
import oshi.software.os.OperatingSystem;

class ComputerIdentifier
{
    static String generateLicenseKey()
    {
        SystemInfo systemInfo = new SystemInfo();
        OperatingSystem operatingSystem = systemInfo.getOperatingSystem();
        HardwareAbstractionLayer hardwareAbstractionLayer = systemInfo.getHardware();
        CentralProcessor centralProcessor = hardwareAbstractionLayer.getProcessor();
        ComputerSystem computerSystem = hardwareAbstractionLayer.getComputerSystem();

        String vendor = operatingSystem.getManufacturer();
        String processorSerialNumber = computerSystem.getSerialNumber();
        String processorIdentifier = centralProcessor.getIdentifier();
        int processors = centralProcessor.getLogicalProcessorCount();

        String delimiter = "#";

        return vendor +
                delimiter +
                processorSerialNumber +
                delimiter +
                processorIdentifier +
                delimiter +
                processors;
    }

    public static void main(String[] arguments)
    {
        String identifier = generateLicenseKey();
        System.out.println(identifier);
    }
}

Output for my machine:

Microsoft#57YRD12#Intel64 Family 6 Model 60 Stepping 3#8

Your output will be different since at least the processor serial number will differ.

My issue is that I ran git diff, then ran git reset --hard HEAD, then realized I wanted to undo, so I tried copying the output from git diff into a file and using git apply, but I got an error that "patch does not apply". After switching to patch and trying to use it, I realized that a chunk of the diff was repeated for some reason, and after removing the duplicate, patch (and presumably also git apply) worked.

It is also used for debugging purposes.

Here is a handy list of some of these values:

http://en.wikipedia.org/wiki/Magic_number_%28programming%29#Magic_debug_values

Right, many alternatives are listed. The easiest and cleanest would be just using the enhanced for statement as below. The Expression is of some type that is iterable.

for ( FormalParameter : Expression ) Statement

For example, to iterate through, List<String> ids, we can simply so,

for (String str : ids) {
    // Do something
}

A stack overflow is usually called by nesting function calls too deeply (especially easy when using recursion, i.e. a function that calls itself) or allocating a large amount of memory on the stack where using the heap would be more appropriate.

Best way to do what you want is to add another server block:

server {
        #implemented by default, change if you need different ip or port
        #listen *:80 | *:8000;
        server_name test.com;
        return 301 $scheme://www.test.com$request_uri;
}

And edit your main server block server_name variable as following:

server_name  www.test.com;

Important: New server block is the right way to do this, if is evil. You must use locations and servers instead of if if it's possible. Rewrite is sometimes evil too, so replaced it with return.

ngModel listens for "input" event, so to "fix" your code you'd need to trigger that event after setting the value:

$('button').click(function(){
    var input = $('input');
    input.val('xxx');
    input.trigger('input'); // Use for Chrome/Firefox/Edge
    input.trigger('change'); // Use for Chrome/Firefox/Edge + IE11
});

For the explanation of this particular behaviour check out this answer that I gave a while ago: "How does AngularJS internally catch events like 'onclick', 'onchange'?"

But unfortunately, this is not the only problem you have. As pointed out with other post comments, your jQuery-centric approach is plain wrong. For more info take a look at this post: How do I “think in AngularJS” if I have a jQuery background?).

1. What is the difference between Git and GitHub?

   Git is a distributed version control system. It usually runs at the command line of your local machine. It keeps track of your files and modifications to those files in a "repository" (or "repo"), but only when you tell it to do so. (In other words, you decide which files to track and when to take a "snapshot" of any modifications.)

   In contrast, GitHub is a website that allows you to publish your Git repositories online, which can be useful for many reasons (see #3).

2. Is Git saving every repository locally (in the user's machine) and in GitHub?

   Git is known as a "distributed" (rather than "centralized") version control system because you can run it locally and disconnected from the Internet, and then "push" your changes to a remote system (such as GitHub) whenever you like. Thus, repo changes only appear on GitHub when you manually tell Git to push those changes.

3. Can you use Git without GitHub? If yes, what would be the benefit for using GitHub?

   Yes, you can use Git without GitHub. Git is the "workhorse" program that actually tracks your changes, whereas GitHub is simply hosting your repositories (and provides additional functionality not available in Git). Here are some of the benefits of using GitHub:

   • It provides a backup of your files.
   • It gives you a visual interface for navigating your repos.
   • It gives other people a way to navigate your repos.
   • It makes repo collaboration easy (e.g., multiple people contributing to the same project).
   • It provides a lightweight issue tracking system.

4. How does Git compare to a backup system such as Time Machine?

   Git does backup your files, though it gives you much more granular control than a traditional backup system over what and when you backup. Specifically, you "commit" every time you want to take a snapshot of changes, and that commit includes both a description of your changes and the line-by-line details of those changes. This is optimal for source code because you can easily see the change history for any given file at a line-by-line level.

5. Is this a manual process, in other words if you don't commit you won't have a new version of the changes made?

   Yes, this is a manual process.

6. If are not collaborating and you are already using a backup system why would you use Git?

   • Git employs a powerful branching system that allows you to work on multiple, independent lines of development simultaneously and then merge those branches together as needed.
   • Git allows you to view the line-by-line differences between different versions of your files, which makes troubleshooting easier.
   • Git forces you to describe each of your commits, which makes it significantly easier to track down a specific previous version of a given file (and potentially revert to that previous version).
   • If you ever need help with your code, having it tracked by Git and hosted on GitHub makes it much easier for someone else to look at your code.

For getting started with Git, I recommend the online book Pro Git as well as GitRef as a handy reference guide. For getting started with GitHub, I like the GitHub's Bootcamp and their GitHub Guides. Finally, I created a short videos series to introduce Git and GitHub to beginners.

Add some inline css to the anchor tag

<li><a style = "color:blue" href="#"><span class="glyphicon glyphicon-user"></span> About</a></li>

This should add the color blue to the anchor tag text.

Just for the sake of completeness, appending values to a vector in a for loop is not really the philosophy in R. R works better by operating on vectors as a whole, as @BrodieG pointed out. See if your code can't be rewritten as:

ouput <- sapply(values, function(v) return(2*v))

Output will be a vector of return values. You can also use lapply if values is a list instead of a vector.

Run these:

$ cd /usr/local/mysql/bin
$ ./mysqladmin -u root password 'password'

Then run

./mysql -u root

It should log in. Now run FLUSH privileges;

Then exit the MySQL console and try logging in. If that doesn't work run these:

$ mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET authentication_string=PASSWORD("XXXXXXX") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit

Change xxxxxx to ur new password. Then try logging in again.

Update. See this http://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html

It should solve your problem.

If you are on oracle try this

ALTER USER username IDENTIFIED BY password

I'm debugging an issue I'm having with SSL connecting to a database (MySQL RDS) using an ORM called, Prisma. The database connection string requires a PKCS12 (.p12) file (if interested, described here), which brought me here.

I know the question has been answered, but I found the following steps (in Github Issue#2676) to be helpful for creating a .p12 file and wanted to share. Good luck!

1. Generate 2048-bit RSA private key:

   openssl genrsa -out key.pem 2048

2. Generate a Certificate Signing Request:

   openssl req -new -sha256 -key key.pem -out csr.csr

3. Generate a self-signed x509 certificate suitable for use on web servers.

   openssl req -x509 -sha256 -days 365 -key key.pem -in csr.csr -out certificate.pem

4. Create SSL identity file in PKCS12 as mentioned here

   openssl pkcs12 -export -out client-identity.p12 -inkey key.pem -in certificate.pem

I had the same error in a report query. I had columns from different tables with the same name and the prefix for each table (eg: select a.description, b.description, c.description) that runs ok in Oracle, but for the report you must have an unique alias for each column so simply add alias to the fields with the same name (select a.description a_description, b.description b_description and so on)

For my case, none of other solutions worked. I had to do a backup of new modified files (shown with git status), and run a git reset --hard. This allowed me to realign with the remote server. Adding new modified files, and running

git add .
git commit -am "my comment"
git push

Did the trick. I hope this helps someone, as a "last chance" solution.

okay it solved, here is my final code

if($(this).width() > $(this).height()) { 
 $(this).css('width',MaxPreviewDimension+'px');
 $(this).css('height','auto');
} else {
 $(this).css('height',MaxPreviewDimension+'px');
 $(this).css('width','auto');
}

Thanks guys

You can use a 1 pixel per 1 pixel Java applet embedded in the page and use that for compression.

It's not JavaScript and the clients will need a Java runtime but it will do what you need.

This should also work (even in SQL-Server 2005):

SELECT *
FROM dbo.MyTable
WHERE Created >= DATEADD(hh,23,DATEADD(day, DATEDIFF(day, 0, Created - 1), 0))
  AND Created <  DATEADD(hh,7,DATEADD(day, DATEDIFF(day, 0, Created), 0))

DEMO

I solved by following these steps:

• Right click in the project > Configure > Convert to Maven project
• After the conversion, right click in the project > Maven > Update project

This fixes the "Deployment Assembly" settings of the project.

Some others figured out that this is wrong. In the meantime i share their opinion. I'm sorry.

Old WRONG answer:

In my opinion this is barely possible.

Your Computer identifies any USB device with the USB device descriptor or the usb interface descriptor. To be able to use your android device as a keyboard, you would have to change these. Actually i think these are saved on a ROM in the device, so you would have to change hardware. The device needs to identifiy itself with the host even if its only charging in turned off state (has to tell usb host about the power consumption, otherwise only a few mA max). For me this points into the direction, that you would have to change hardware

"Easiest" way would proabably be assemble an adapter containing a usb host chip with a µC that converts the received data (which you still had to send via usb) to ps/2 or usb-client signals that u send to the computer.

In my opinion the easiest way would be: Buy one of these Keyboards you can roll and put them in your bag too.

1. Click on Change Connection icon
2. Click Options<<
3. Select the db from Connect to database drop down

This could be updated to ES6 with arrow functions and look like:

getFeed().then(data => vm.feed = data);

If you wish to use the async function, you could also do like that:

async function myFunction(){
    vm.feed = await getFeed();
    // do whatever you need with vm.feed below
 }

I solved it by changing the "lock" property from "shared" to "exclusive":

ALTER TABLE `table` 
CHANGE COLUMN `ID` `ID` INT(11) NOT NULL AUTO_INCREMENT COMMENT '' , LOCK = EXCLUSIVE;

I had a similar problem with Ant build (started by hand from IDEA GUI). In my case there was the right solution to right click on the Ant task, choose properties and set a higher value to "Maximum heap space (Mb):" and "Maximum stack space (Mb):" input fields.

The existing answers are outdated. This is now doable from the menu:

Window -> Restore Default Layout (shift+f12)

Make sure nothing is currently running, as the Run/Debug window layout will not be reset otherwise.

Trying to upload a GoDaddy certificate to AWS I failed several times, but in the end it was pretty simple. No need to convert anything to .pem. You just have to be sure to include the GoDaddy bundle certificate in the chain parameter, e.g.

aws iam upload-server-certificate
    --server-certificate-name mycert
    --certificate-body file://try2/40271b1b25236fd1.crt
    --private-key file://server.key
    --path /cloudfront/production/
    --certificate-chain file://try2/gdig2_bundle.crt

And to delete your previous failed upload you can do

aws iam delete-server-certificate --server-certificate-name mypreviouscert

If 2 decimal places is your level of precision, then a "smallint" would handle this in the smallest space (2-bytes). You store the percent multiplied by 100.

EDIT: The decimal type is probably a better match. Then you don't need to manually scale. It takes 5 bytes per value.

Just Do like this

view.animate()
            .translationY(-((root.height - (view.height)) / 2).toFloat())
            .setInterpolator(AccelerateInterpolator()).duration = 1500

Here, view is your View which is animating from its origin position. root is root View of your XML file.

Calculation inside translationY is made for moving your view to the top but keeping it inside the screen, otherwise, it will go partially outside of the screen if you keep its value 0.

Sometimes, you just want to have a look at previous copies of files without the rigmarole of going through the diffs.

In such a case, it's just as easy to make a clone of a repository and checkout the specific commit that you are interested in and have a look at the subdirectory in that cloned repository. Because everything is local you can just delete this clone when you are done.

Take a look at section 9.2.: Maven Properties of the free online book Maven: The Complete Reference.

Can I try? ;)

based on Dirk's solution

final int digits = number==0?1:(1 + (int)Math.floor(Math.log10(Math.abs(number))));

Late one but gives more details that might be useful…

Here is a list of things you can do with advantages and disadvantages

Generate scripts using SSMS

• Pros: extremely easy to use and supported by default
• Cons: scripts might not be in the correct execution order and you might get errors if stored procedure already exists on secondary database. Make sure you review the script before executing.

Third party tools

• Pros: tools such as ApexSQL Diff (this is what I use but there are many others like tools from Red Gate or Dev Art) will compare two databases in one click and generate script that you can execute immediately
• Cons: these are not free (most vendors have a fully functional trial though)

System Views

• Pros: You can easily see which stored procedures exist on secondary server and only generate those you don’t have.
• Cons: Requires a bit more SQL knowledge

Here is how to get a list of all procedures in some database that don’t exist in another database

select *
from DB1.sys.procedures P
where P.name not in 
 (select name from DB2.sys.procedures P2)

Edit: Don't miss Stefan's solution above, which uses the very handy http_build_query() function: https://stackoverflow.com/a/1764199/179125

knittl is right on about escaping. However, there's a simpler way to do this:

$url = 'http://example.com/index.php?';
$url .= 'aValues[]=' . implode('&aValues[]=', array_map('urlencode', $aValues));

If you want to do this with an associative array, try this instead:

PHP 5.3+ (lambda function)

$url = 'http://example.com/index.php?';
$url .= implode('&', array_map(function($key, $val) {
    return 'aValues[' . urlencode($key) . ']=' . urlencode($val);
  },
  array_keys($aValues), $aValues)
);

PHP <5.3 (callback)

function urlify($key, $val) {
  return 'aValues[' . urlencode($key) . ']=' . urlencode($val);
}

$url = 'http://example.com/index.php?';
$url .= implode('&', array_map('urlify', array_keys($aValues), $aValues));

This might work for you (GNU sed):

sed ':a;$!N;1,4ba;P;$d;D' file

In my case Anaconda3 was not installed in home directory. Instead, it was installed in root. Therefore, I had to do the following to get it uninstalled:

sudo rm -rf /anaconda3/bin/python

It is possible. Have a look at JSch.addIdentity(...)

This allows you to use key either as byte array or to read it from file.

            String user = "tjill";
            String host = "192.18.0.246";
            int port = 10022;
            String privateKey = ".ssh/id_rsa";

            jsch.addIdentity(privateKey);
            System.out.println("identity added ");

            Session session = jsch.getSession(user, host, port);

This functionality has been added to the IDE now (working Pycharm 2018.3)

Just click the EnvFile tab in the run configuration, click Enable EnvFile and click the + icon to add an env file

Update: Essentially the same as the answer by @imguelvargasf but the the plugin was enabled by default for me.

I usually insert a blockquote and add a Unicode character(memo which is(U+1F4DD)) inside it.

...

Emoji

Of course, if you do not like you can search you like. I am sure there will be one in it is your satisfaction!

• find more emoji: https://emojipedia.org/

  just search you like icon and copy-paste then done(since it is a character, so it suitable for every device)

• find Code

  If you don't like copy paste and want to type yourself, you can consider searching the Unicode.

  

p.s. You can also pay attention to the emoji version (usually it is the same as the Unicode version), and more icons may appear in the future to your satisfaction.

• Unicode Version 14.0
• Emoji Version 14.0

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

Steps to start Apache Tomcat using cmd:
1. Firstly check that the JRE_HOME or JAVA_HOME is a variable available in environment variables.(If it is not create a new variable JRE_HOME or JAVA_HOME)
2. Goto cmd and change your working directory to bin path where apache is installed (or extracted).
3. Type Command -> catalina.bat start to start the server.
4. Type Command -> catalina.bat stop to stop the server.

Use the format() method for objects of class "yearmon". Here is your example date (properly created!)

date1 <- as.yearmon("Mar 2012", "%b %Y")

Then we can extract the date parts as required:

> format(date1, "%b") ## Month, char, abbreviated
[1] "Mar"
> format(date1, "%Y") ## Year with century
[1] "2012"
> format(date1, "%m") ## numeric month
[1] "03"

These are returned as characters. Where appropriate, wrap in as.numeric() if you want the year or numeric month as a numeric variable, e.g.

> as.numeric(format(date1, "%m"))
[1] 3
> as.numeric(format(date1, "%Y"))
[1] 2012

See ?yearmon and ?strftime for details - the latter explains the placeholder characters you can use.

What I have noticed apart from next() scans only upto space where as nextLine() scans the entire line is that next waits till it gets a complete token where as nextLine() does not wait for complete token, when ever '\n' is obtained(i.e when you press enter key) the scanner cursor moves to the next line and returns the previous line skipped. It does not check for the whether you have given complete input or not, even it will take an empty string where as next() does not take empty string

public class ScannerTest {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        int cases = sc.nextInt();
        String []str = new String[cases];
        for(int i=0;i<cases;i++){
            str[i]=sc.next();
        }
     }

}

Try this program by changing the next() and nextLine() in for loop, go on pressing '\n' that is enter key without any input, you can find that using nextLine() method it terminates after pressing given number of cases where as next() doesnot terminate untill you provide and input to it for the given number of cases.

Sometimes I wish it were possible to write a function in MSIL inline in C#, similar to how you can write inline assembler in C.

For the record, I once wrote a helper library for C# with various functions for things that were impossible to write in C# but can be written in MSIL (non-zero-based arrays for example). I had this function:

.method public hidebysig static void Swap<T> (
        !!T& a,
        !!T& b
    ) cil managed 
{
    .maxstack 4

    ldarg.1      // push a& reference
    ldarg.2      // push b& reference
    ldobj !!T    // pop b&, push b
    ldarg.2      // push b& reference
    ldarg.1      // push a& reference
    ldobj !!T    // pop a&, push a
    stobj !!T    // store a in b&
    stobj !!T    // store b in a&
    ret
}

And no locals needed. Of course this was just me being silly...

I can think of one unfortunate side-effect. In java embedded databases, the number of ids you can have with a 32bit id field is 2^31, not 2^32 (~2billion, not ~4billion).

That is because Low is a string.

.toFixed() only works with a number.

Try doing:

Low = parseFloat(Low).toFixed(..);

The easiest way to do this in one command is to use which command and also need not to change the factors into character by doing this:

junk$nm[which(junk$nm=="B")]<-"b"

You're resetting the margin on all elements in the second css block. Default margin is 40px - this should solve the problem:

.my_container ul {list-style:disc outside none; margin-left:40px;}

Abstract:

The reason why you are getting this error message is because you are trying to call a method on an int type of a variable. This would work if would have called len() function on a list type of a variable. Let's examin the two cases:

Fail:

num = 10

print(len(num))

The above will produce an error similar to yours due to calling len() function on an int type of a variable;

Success:

data = [0, 4, 8, 9, 12]

print(len(data))

The above will work since you are calling a function on a list type of a variable;

you can try this.

data_you_need=pd.DataFrame()
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    data_you_need=data_you_need.append(data,ignore_index=True)

I hope it can help.

I generally subscribe to the following convention:

• Trace - Only when I would be "tracing" the code and trying to find one part of a function specifically.
• Debug - Information that is diagnostically helpful to people more than just developers (IT, sysadmins, etc.).
• Info - Generally useful information to log (service start/stop, configuration assumptions, etc). Info I want to always have available but usually don't care about under normal circumstances. This is my out-of-the-box config level.
• Warn - Anything that can potentially cause application oddities, but for which I am automatically recovering. (Such as switching from a primary to backup server, retrying an operation, missing secondary data, etc.)
• Error - Any error which is fatal to the operation, but not the service or application (can't open a required file, missing data, etc.). These errors will force user (administrator, or direct user) intervention. These are usually reserved (in my apps) for incorrect connection strings, missing services, etc.
• Fatal - Any error that is forcing a shutdown of the service or application to prevent data loss (or further data loss). I reserve these only for the most heinous errors and situations where there is guaranteed to have been data corruption or loss.

I have a situation where I want data from up to two days ago and up until the end of today. I arrived at the following.

WHERE dateTimeRecorded between date('now', 'start of day','-2 days') 
                           and date('now', 'start of day', '+1 day') 

Ok, technically I also pull in midnight on tomorrow like the original poster, if there was any data, but my data is all historical.

The key thing to remember, the initial poster excluded all data after 2009-11-15 00:00:00. So, any data that was recorded at midnight on the 15th was included but any data after midnight on the 15th was not. If their query was,

select * 
  from table_1 
  where mydate between Datetime('2009-11-13 00:00:00') 
                   and Datetime('2009-11-15 23:59:59')

Use of the between clause for clarity.

It would have been slightly better. It still does not take into account leap seconds in which an hour can actually have more than 60 seconds, but good enough for discussions here :)

From the asar documentation

In Kotlin,

You have to override getHeaders() method like :

val volleyEnrollRequest = object : JsonObjectRequest(GET_POST_PARAM, TARGET_URL, PAYLOAD_BODY_IF_YOU_WISH,
            Response.Listener {
                // Success Part  
            },

            Response.ErrorListener {
                // Failure Part
            }
        ) {
            // Providing Request Headers

            override fun getHeaders(): Map<String, String> {
               // Create HashMap of your Headers as the example provided below

                val headers = HashMap<String, String>()
                headers["Content-Type"] = "application/json"
                headers["app_id"] = APP_ID
                headers["app_key"] = API_KEY

                return headers
            }
        }

Use the Linux split command:

split -l 20 file.txt new    

Split the file "file.txt" into files beginning with the name "new" each containing 20 lines of text each.

Type man split at the Unix prompt for more information. However you will have to first remove the header from file.txt (using the tail command, for example) and then add it back on to each of the split files.

I have gone through some basic javascript example using onkeypress and onchange event handlers for making binding view to our js and js to view

Here example plunker http://plnkr.co/edit/7hSOIFRTvqLAvdZT4Bcc?p=preview

<!DOCTYPE html>
<html>
<body>

    <p>Two way binding data.</p>

    <p>Binding data from  view to JS</p>

    <input type="text" onkeypress="myFunction()" id="myinput">
    <p id="myid"></p>
    <p>Binding data from  js to view</p>
    <input type="text" id="myid2" onkeypress="myFunction1()" oninput="myFunction1()">
    <p id="myid3" onkeypress="myFunction1()" id="myinput" oninput="myFunction1()"></p>

    <script>

        document.getElementById('myid2').value="myvalue from script";
        document.getElementById('myid3').innerHTML="myvalue from script";
        function myFunction() {
            document.getElementById('myid').innerHTML=document.getElementById('myinput').value;
        }
        document.getElementById("myinput").onchange=function(){

            myFunction();

        }
        document.getElementById("myinput").oninput=function(){

            myFunction();

        }

        function myFunction1() {

            document.getElementById('myid3').innerHTML=document.getElementById('myid2').value;
        }
    </script>

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

You need to pass optimized: false.

E.g.

var img = { url: 'img/puff.svg', scaledSide: new google.maps.Size(5, 5) };
new google.maps.Marker({position: this.mapOptions.center, map: this.map, icon: img, optimized: false,});

Without passing optimized: false, my svg appeared as a static image.

Using true/false removes some bracket clutter...

#! /bin/bash    
#  true_or_false.bash

[ "$(basename $0)" == "bash" ] && sourced=true || sourced=false

$sourced && echo "SOURCED"
$sourced || echo "CALLED"

# Just an alternate way:
! $sourced  &&  echo "CALLED " ||  echo "SOURCED"

$sourced && return || exit

The optimal solution for this is provide it as '0' and while using string use it as 'null' when using integer.

ex:

INSERT INTO table_name(column_name) VALUES(NULL);

For me, the simplest way to use ALIAS in WHERE class is to create a subquery and select from it instead.

Example:

WITH Q1 AS (
    SELECT LENGTH(name) AS name_length,
    id,
    name
    FROM any_table
)

SELECT id, name, name_length form Q1 where name_length > 0

Cheers, Kel

Yes, if such precision is required use System.nanoTime(), but be aware that you are then requiring a Java 5+ JVM.

On my XP systems, I see system time reported to at least 100 microseconds 278 nanoseconds using the following code:

private void test() {
    System.out.println("currentTimeMillis: "+System.currentTimeMillis());
    System.out.println("nanoTime         : "+System.nanoTime());
    System.out.println();

    testNano(false);                                                            // to sync with currentTimeMillis() timer tick
    for(int xa=0; xa<10; xa++) {
        testNano(true);
        }
    }

private void testNano(boolean shw) {
    long strMS=System.currentTimeMillis();
    long strNS=System.nanoTime();
    long curMS;
    while((curMS=System.currentTimeMillis()) == strMS) {
        if(shw) { System.out.println("Nano: "+(System.nanoTime()-strNS)); }
        }
    if(shw) { System.out.println("Nano: "+(System.nanoTime()-strNS)+", Milli: "+(curMS-strMS)); }
    }

This question is a bit old, but here's another way in C++11 of "doing more work" in the constructor before initialising your member variables:

BigMommaClass::BigMommaClass(int numba1, int numba2)
    : thingOne([](int n1, int n2){return n1+n2;}(numba1,numba2)),
      thingTwo(numba1, numba2) {}

The lambda function above will be invoked and the result passed to thingOnes constructor. You can of course make the lambda as complex as you like.

The JPA @Column Annotation

The nullable attribute of the @Column annotation has two purposes:

• it's used by the schema generation tool
• it's used by Hibernate during flushing the Persistence Context

Schema Generation Tool

The HBM2DDL schema generation tool translates the @Column(nullable = false) entity attribute to a NOT NULL constraint for the associated table column when generating the CREATE TABLE statement.

As I explained in the Hibernate User Guide, it's better to use a tool like Flyway instead of relying on the HBM2DDL mechanism for generating the database schema.

Persistence Context Flush

When flushing the Persistence Context, Hibernate ORM also uses the @Column(nullable = false) entity attribute:

new Nullability( session ).checkNullability( values, persister, true );

If the validation fails, Hibernate will throw a PropertyValueException, and prevents the INSERT or UPDATE statement to be executed needesly:

if ( !nullability[i] && value == null ) {
    //check basic level one nullablilty
    throw new PropertyValueException(
            "not-null property references a null or transient value",
            persister.getEntityName(),
            persister.getPropertyNames()[i]
        );    
}

The Bean Validation @NotNull Annotation

The @NotNull annotation is defined by Bean Validation and, just like Hibernate ORM is the most popular JPA implementation, the most popular Bean Validation implementation is the Hibernate Validator framework.

When using Hibernate Validator along with Hibernate ORM, Hibernate Validator will throw a ConstraintViolation when validating the entity.

Not enough rep for a comment.

The getElementById() based method in the selected answer won't work if the anchor has name but not id set (which is not recommended, but does happen in the wild).

Something to bare in mind if you don't have control of the document markup (e.g. webextension).

The location based method in the selected answer can also be simplified with location.replace:

function jump(hash) { location.replace("#" + hash) }

You can also use:

var obj = {
    alert: alert.bind(window)
};
obj.alert('I´m an alert!!');

Suppose originally there were 3 commits, A,B,C:

Then developer Dan created commit D, and developer Ed created commit E:

Obviously, this conflict should be resolved somehow. For this, there are 2 ways:

MERGE:

Both commits D and E are still here, but we create merge commit M that inherits changes from both D and E. However, this creates diamond shape, which many people find very confusing.

REBASE:

We create commit R, which actual file content is identical to that of merge commit M above. But, we get rid of commit E, like it never existed (denoted by dots - vanishing line). Because of this obliteration, E should be local to developer Ed and should have never been pushed to any other repository. Advantage of rebase is that diamond shape is avoided, and history stays nice straight line - most developers love that!

A simpler way is

ggplot(data=df, aes(x=xvar, y=yvar)) + 
geom_point()

ggsave(path = path, width = width, height = height, device='tiff', dpi=700)

I had the same problem with the laravel initiation. The solution was as follows.

1st - I checked the version of my PHP. That it was 5.6 would soon give problem with the laravel.

2nd - I changed the version of my PHP to PHP 7.1.1. ATTENTION, in my case I changed my environment variable that was getting Xampp's PHP version 5.6 I changed to 7.1.1 for laragon.

3rd - I went to the terminal / console and navigated to my folder where my project was and typed the following command: php artisan serves. And it worked! In my case it started at the port: 8000 see example below.

C: \ laragon \ www \ first> php artisan serves Laravel development server started: http://127.0.0.1:8000

I hope I helped someone who has been through the same problem as me.

Suppose you have a tree like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]

First, checkout a temp branch:

git checkout -b temp

On temp branch, reset --hard to a commit that you want to change its message (for example, that commit is 946992):

git reset --hard 946992

Use amend to change the message:

git commit --amend -m "<new_message>"

After that the tree will look like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
           \
            b886a0 [temp]

Then, cherry-pick all the commit that is ahead of 946992 from master to temp and commit them, use amend if you want to change their messages as well:

git cherry-pick 9143a9
git commit --amend -m "<new_message>
...
git cherry-pick 5a6057
git commit --amend -m "<new_message>

The tree now looks like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
               \
                b886a0 - 41ab2c - 6c2a3s - 7c88c9 [temp]

Now force push the temp branch to remote:

git push --force origin temp:master

The final step, delete branch master on local, git fetch origin to pull branch master from the server, then switch to branch master and delete branch temp.

Now both your local and remote will have all the messages updated.

Despite the danger of stating the obvious: With a unit test you want to test the correct behaviour of the object - and this is defined in terms of its public interface. You are not interested in how the object accomplishes this task - this is an implementation detail and not visible to the outside. This is one of the things why OO was invented: That implementation details are hidden. So there is no point in testing private members. You said you need 100% coverage. If there is a piece of code that cannot be tested by using the public interface of the object, then this piece of code is actually never called and hence not testable. Remove it.

If the list is sorted, you can use the Get-Unique cmdlet:

 $a | Get-Unique

Using formula from: https://en.wikipedia.org/wiki/Line%E2%80%93line_intersection

 def findIntersection(x1,y1,x2,y2,x3,y3,x4,y4):
        px= ( (x1*y2-y1*x2)*(x3-x4)-(x1-x2)*(x3*y4-y3*x4) ) / ( (x1-x2)*(y3-y4)-(y1-y2)*(x3-x4) ) 
        py= ( (x1*y2-y1*x2)*(y3-y4)-(y1-y2)*(x3*y4-y3*x4) ) / ( (x1-x2)*(y3-y4)-(y1-y2)*(x3-x4) )
        return [px, py]

Modern BASH has support for regular expressions:

while read -r line; do
  if [[ $line =~ ^potato:\ ([0-9]+) ]]; then
    echo "${BASH_REMATCH[1]}"
  fi
done

If working with data, many times pandas is the simple key

This particular code will put the raw into one column, then normalize by column per row. (But we can put it into a row and do it by row per column, too! Just have to change the axis values where 0 is for row and 1 is for column.)

import pandas as pd


raw = [0.07, 0.14, 0.07]  

raw_df = pd.DataFrame(raw)
normed_df = raw_df.div(raw_df.sum(axis=0), axis=1)
normed_df

where normed_df will display like:

    0
0   0.25
1   0.50
2   0.25

and then can keep playing with the data, too!

This is a very partial answer to your question, but I hope still useful.

Microsoft SQL Server 2008 implements two features that are extremely useful for managing hierarchical data:

• the HierarchyId data type.
• common table expressions, using the with keyword.

Have a look at "Model Your Data Hierarchies With SQL Server 2008" by Kent Tegels on MSDN for starts. See also my own question: Recursive same-table query in SQL Server 2008

I ever met some pitfalls about lexical declarations in Perl that messed me up, which are also related to this question, so I just add my summary here:

1. Definition or declaration?

local $var = 42;
print "var: $var\n";

The output is var: 42. However we couldn't tell if local $var = 42; is a definition or declaration. But how about this:

use strict;
use warnings;

local $var = 42;
print "var: $var\n";

The second program will throw an error:

Global symbol "$var" requires explicit package name.

$var is not defined, which means local $var; is just a declaration! Before using local to declare a variable, make sure that it is defined as a global variable previously.

But why this won't fail?

use strict;
use warnings;

local $a = 42;
print "var: $a\n";

The output is: var: 42.

That's because $a, as well as $b, is a global variable pre-defined in Perl. Remember the sort function?

2. Lexical or global?

I was a C programmer before starting using Perl, so the concept of lexical and global variables seems straightforward to me: it just corresponds to auto and external variables in C. But there're small differences:

In C, an external variable is a variable defined outside any function block. On the other hand, an automatic variable is a variable defined inside a function block. Like this:

int global;

int main(void) {
    int local;
}

While in Perl, things are subtle:

sub main {
    $var = 42;
}

&main;

print "var: $var\n";

The output is var: 42. $var is a global variable even if it's defined in a function block! Actually in Perl, any variable is declared as global by default.

The lesson is to always add use strict; use warnings; at the beginning of a Perl program, which will force the programmer to declare the lexical variable explicitly, so that we don't get messed up by some mistakes taken for granted.

The .Date answer is misleading since you get the error mentioned before. Another way to compare, other than mentioned DbFunctions.TruncateTime, may also be:

DateTime today = DateTime.Now.date;
var q = db.Games.Where(t => SqlFunctions.DateDiff("dayofyear", today, t.StartDate) <= 0
      && SqlFunctions.DateDiff("year", today, t.StartDate) <= 0)

It looks better(more readable) in the generated SQL query. But I admit it looks worse in the C# code XD. I was testing something and it seemed like TruncateTime was not working for me unfortunately the fault was between keyboard and chair, but in the meantime I found this alternative.

Without Random solution:

   static void randomArrTimest(int[] some){
        long startTime = System.currentTimeMillis();
        for (int i = 0; i < some.length; i++) {
            long indexToSwap = startTime%(i+1);
            long tmp = some[(int) indexToSwap];
            some[(int) indexToSwap] = some[i];
            some[i] = (int) tmp;
        }
        System.out.println(Arrays.toString(some));
    }

An example of making an array from HTMLCollection

<ul id="myList">
    <li>0</li>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
</ul>

<script>
var tagList = [];

var ulList = document.getElementById("myList");

var tags   = ulList.getElementsByTagName("li");

//Dump elements into Array
while( tagList.length != tags.length){
    tagList.push(tags[tagList.length])
};

tagList.forEach(function(item){
        item.addEventListener("click", function (event){ 
            console.log(tagList.indexOf( event.target || event.srcElement));
        });
}); 
</script>

Find a parent of current element that has vertical scrolling or body.

$.fn.scrollableParent = function() {
    var $parents = this.parents();

    var $scrollable = $parents.filter(function(idx) {
        return this.scrollHeight > this.offsetHeight && this.offsetWidth !== this.clientWidth;
    }).first();

    if ($scrollable.length === 0) {
        $scrollable = $('html, body');
    }
    return $scrollable;
};

It may be used to autoscroll to current element via:

var $scrollable = $elem.scrollableParent();
$scrollable.scrollTop($elem.position().top);

There are two ways:

1. Use the axes methods of the subplot object (e.g. ax.set_xticks and ax.set_xticklabels) or
2. Use plt.sca to set the current axes for the pyplot state machine (i.e. the plt interface).

As an example (this also illustrates using setp to change the properties of all of the subplots):

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=3, ncols=4)

# Set the ticks and ticklabels for all axes
plt.setp(axes, xticks=[0.1, 0.5, 0.9], xticklabels=['a', 'b', 'c'],
        yticks=[1, 2, 3])

# Use the pyplot interface to change just one subplot...
plt.sca(axes[1, 1])
plt.xticks(range(3), ['A', 'Big', 'Cat'], color='red')

fig.tight_layout()
plt.show()

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

Fastest and simpliest way is to save XLS as ODS (open document spreasheet) and import it from PhpMyAdmin

After doing some more googling I came across the float package which lets you prevent LaTeX from repositioning the tables.

In the preamble:

\usepackage{float}
\restylefloat{table}

Then for each table you can use the H placement option (e.g. \begin{table}[H]) to make sure it doesn't get repositioned.

Try this: B = A ( : ), or try the reshape function.

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/reshape.html

It's easier than it is thought:

my_str = "hello world"
my_str_as_bytes = str.encode(my_str)
type(my_str_as_bytes) # ensure it is byte representation
my_decoded_str = my_str_as_bytes.decode()
type(my_decoded_str) # ensure it is string representation

If you downloaded package that has "setup.py" in root folder, you can install it by running

python setup.py install

Nobody mentioned the limit on the size of the stack frame.

There are two places memory can be allocated:

• On the heap (dynamically allocated memory).
  The size limit here is a combination of available hardware and the OS's ability to simulate space by using other devices to temporarily store unused data (i.e. move pages to hard disk).
• On the stack (Locally declared variables).
  The size limit here is compiler defined (with possible hardware limits). If you read the compiler documentation you can often tweak this size.

Thus if you allocate an array dynamically (the limit is large and described in detail by other posts.

int* a1 = new int[SIZE];  // SIZE limited only by OS/Hardware

Alternatively if the array is allocated on the stack then you are limited by the size of the stack frame. N.B. vectors and other containers have a small presence in the stack but usually the bulk of the data will be on the heap.

int a2[SIZE]; // SIZE limited by COMPILER to the size of the stack frame

This NSString category uses the NSXMLParser to accurately remove any HTML tags from an NSString. This is a single .m and .h file that can be included into your project easily.

https://gist.github.com/leighmcculloch/1202238

You then strip html by doing the following:

Import the header:

#import "NSString_stripHtml.h"

And then call stripHtml:

NSString* mystring = @"<b>Hello</b> World!!";
NSString* stripped = [mystring stripHtml];
// stripped will be = Hello World!!

This also works with malformed HTML that technically isn't XML.

double myDb = 12.3;
int myInt = (int) myDb;

Result is: myInt = 12

My experience:

  var text = $('#myInputField');  
  var myObj = {title: 'Some title', content: text};  
  $.post(myUrl, myObj, callback);

The problem is that I forgot to add .val() to the end of $('#myInputField'); this action makes me waste time trying to figure out what was wrong, causing Illegal Invocation Error, since $('#myInputField') was in a different file than that system pointed out incorrect code. Hope this answer help fellows in the same mistake to avoid to loose time.

loadXMLDoc JS function should return false, otherwise it will result in postback.

UseEnvironment.NewLine instead of vbcrlf

Check your manifest.xml. Make sure you have the category LAUNCHER there.

<activity android:name=".myActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>
    </activity>

regexObject.test( String ) is faster than string.match( RegExp ).

The MDN site describes the format for document.cookie, and has an example regex to grab a cookie (document.cookie.replace(/(?:(?:^|.*;\s*)test2\s*\=\s*([^;]*).*$)|^.*$/, "$1");). Based on that, I'd go for this:

/^(.*;)?\s*cookie1\s*=/.test(document.cookie);

The question seems to ask for a solution which returns false when the cookie is set, but empty. In that case:

/^(.*;)?\s*cookie1\s*=\s*[^;]/.test(document.cookie);

Tests

function cookieExists(input) {return /^(.*;)?\s*cookie1\s*=/.test(input);}
function cookieExistsAndNotBlank(input) {return /^(.*;)?\s*cookie1\s*=\s*[^;]/.test(input);}
var testCases = ['cookie1=;cookie1=345534;', 'cookie1=345534;cookie1=;', 'cookie1=345534;', ' cookie1 = 345534; ', 'cookie1=;', 'cookie123=345534;', 'cookie=345534;', ''];
console.table(testCases.map(function(s){return {'Test String': s, 'cookieExists': cookieExists(s), 'cookieExistsAndNotBlank': cookieExistsAndNotBlank(s)}}));

You can try using JavaScript's Date Object

new Date(year,month).getFullYear()%4==0

This will return true or false.

A jar file is a zip archive. You can extract it using 7zip (a great simple tool to open archives). You can also change its extension to zip and use whatever to unzip the file.

Now you have your class file. There is no easy way to edit class file, because class files are binaries (you won't find source code in there. maybe some strings, but not java code). To edit your class file you can use a tool like classeditor.

You have all the strings your class is using hard-coded in the class file. So if the only thing you would like to change is some strings you can do it without using classeditor.

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

Yes, you can program Android apps in C++ (for the most part), using the Native Development Kit (NDK), although Java is the primary/preferred language for programming Android, and your C++ code will likely have to interface with Java components, and you'll likely need to read and understand the documentation for Java components, as well. Therefore, I'd advise you to use Java unless you have some existing C++ code base that you need to port and that isn't practical to rewrite in Java.

Java is very similar to C++, I don't think you will have any problems picking it up... going from C++ to Java is incredibly easy; going from Java to C++ is a little more difficult, though not terrible. Java for C++ Programmers does a pretty good job at explaining the differences. Writing your Android code in Java will be more idiomatic and will also make the development process easier for you (as the tooling for the Java Android SDK is significantly better than the corresponding NDK tooling)

In terms of setup, Google provides the Android Studio IDE for both Java and C++ Android development (with Gradle as the build system), but you are free to use whatever IDE or build system you want so long as, under the hood, you are using the Android SDK / NDK to produce the final outputs.

If you happen to need this in Android and want to make it work with anything older than FroYo, you can also use EncodingUtils.getAsciiBytes():

byte[] bytes = EncodingUtils.getAsciiBytes("ASCII Text");

Syntax looks like:

$ split [OPTION] [INPUT [PREFIX]] 

where prefix is PREFIXaa, PREFIXab, ...

Just use proper one and youre done or just use mv for renameing. I think $ mv * *.txt should work but test it first on smaller scale.

:)

Important step for Event binding on Ajax loading content...

01. First of all unbind or off the event on selector

$(".SELECTOR").off();

02. Add event listener on document level

$(document).on("EVENT", '.SELECTOR', function(event) { 
    console.log("Selector event occurred");
});

Thank you @Razvan who pointed me in the right direction. I was able to get it in one line and I successfully hunted down the imports for Hamcrest 1.3.

the imports:

import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.Matchers.contains;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.beans.HasPropertyWithValue.hasProperty;

the code:

assertThat( myClass.getMyItems(), contains(
    hasProperty("name", is("foo")), 
    hasProperty("name", is("bar"))
));

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

For more details, see this question: Division in Python 2.7. and 3.3

'continue' is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.

'break' ends execution of the current for, foreach, while, do-while or switch structure.

break accepts an optional numeric argument which tells it how many nested enclosing structures are to be broken out of.

Check out the following links:

http://www.php.net/manual/en/control-structures.break.php

Hope it helps..

Make use of the zfill() helper method to left-pad any string, integer or float with zeros; it's valid for both Python 2.x and Python 3.x.

Sample usage:

print str(1).zfill(3);
# Expected output: 001

Description:

When applied to a value, zfill() returns a value left-padded with zeros when the length of the initial string value less than that of the applied width value, otherwise, the initial string value as is.

Syntax:

str(string).zfill(width)
# Where string represents a string, an integer or a float, and
# width, the desired length to left-pad.

There is also another easy way to check the latest version without going to NPM if you are using VS Code.

In package.json file check for the module you want to know the latest version. Remove the current version already present there and do CTRL + space or CMD + space(mac).The VS code will show the latest versions

Related to your question, you may want to consider limiting the amount of RAM SQL Server has access to if you are using it in a shared environment, i.e., on a server that hosts more than just SQL Server:

1. Start > All Programs > Microsoft SQL Server 2005: SQL Server Management Studio.
2. Connect using whatever account has admin rights.
3. Right click on the database > Properties.
4. Select "Memory" from the left pane and then change the "Server memory options" to whatever you feel should be allocated to SQL Server.

This will help alleviate SQL Server from consuming all the server's RAM.

You can stash your local changes first, then pull, then pop the stash.

git stash
git pull origin master
git stash pop

Anything that overrides changes from remote will have conflicts which you will have to manually resolve.

In python 3, you can use:

import locale
locale.setlocale( locale.LC_ALL, 'English_United States.1252' )
locale.currency( 1234.50, grouping = True )

Output

'$1,234.50'

Another Solution!

If you want to set widgets in center vertical form, you can use ListView for it. for eg: I used three buttons and add them inside ListView which followed by

shrinkWrap: true -> With this ListView only occupies the space which needed.

import 'package:flutter/material.dart';

class List extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final button1 =
        new RaisedButton(child: new Text("Button1"), onPressed: () {});
    final button2 =
        new RaisedButton(child: new Text("Button2"), onPressed: () {});
    final button3 =
        new RaisedButton(child: new Text("Button3"), onPressed: () {});
    final body = new Center(
      child: ListView(
        shrinkWrap: true,
        children: <Widget>[button1, button2, button3],
     ),
    );

    return new Scaffold(
        appBar: new AppBar(
          title: Text("Sample"),
        ),
        body: body);
  }
}    
void main() {
  runApp(new MaterialApp(
    home: List(),
  ));
}

Output:

Fetch id basing on name

 {
    "roles": [
     {
      "id": 1,
      "name": "admin",
     },
     {
      "id": 3,
      "name": "manager",
     }
    ]
    }



    fetchIdBasingOnRole() {
          const self = this;
          if (this.employee.roles) {
            var roleid = _.result(
              _.find(this.getRoles, function(obj) {
                return obj.name === self.employee.roles;
              }),
              "id"
            );
          }
          return roleid;
        },

If you aren't particularly concerned with the length of the key, a pretty tried and true method is the use of public and private key encryption.

Essentially have some kind of nonce and a fixed signature.

For example: 0001-123456789

Where 0001 is your nonce and 123456789 is your fixed signature.

Then encrypt this using your private key to get your CD key which is something like: ABCDEF9876543210

Then distribute the public key with your application. The public key can be used to decrypt the CD key "ABCDEF9876543210", which you then verify the fixed signature portion of.

This then prevents someone from guessing what the CD key is for the nonce 0002 because they don't have the private key.

The only major down side is that your CD keys will be quite long when using private / public keys 1024-bit in size. You also need to choose a nonce long enough so you aren't encrypting a trivial amount of information.

The up side is that this method will work without "activation" and you can use things like an email address or licensee name as the nonce.

I think in this case they are the same, but here is an example where order matters:

const int* cantChangeTheData;
int* const cantChangeTheAddress;

So easy way :

XML:

<android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fff"/>
<android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Java code:

private ViewPager viewPager;

private String[] PAGE_TITLES = new String[]{
        "text1",
        "text1",
        "text3"
};
private final Fragment[] PAGES = new Fragment[]{
        new fragment1(), 
        new fragment2(),
        new fragment3()

};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_a_requests);

    /**TODO ***************tebLayout*************************/
    viewPager = findViewById(R.id.viewpager);
    viewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
    TabLayout tabLayout = findViewById(R.id.tab_layout);
    tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#1f57ff"));
    tabLayout.setSelectedTabIndicatorHeight((int) (4 * 
    getResources().getDisplayMetrics().density));
    tabLayout.setTabTextColors(Color.parseColor("#9d9d9d"), 
    Color.parseColor("#0d0e10"));
    tabLayout.setupWithViewPager(viewPager);
    /***************************************************************************/
    }

Before you run the $object through a foreach loop you have to convert it to an array:

$array = (array) $object;  

 foreach($array as $key=>$val){
      echo "$key: $val";
      echo "<br>";
 }

you can use..

<div style="width: 100%;">
   <div style="float:left; width: 80%">
   </div>
   <div style="float:right;">
   </div>
</div>
<div style="clear:both"></div>

now element below this will not be affected.

Here is one way of doing it.

Without actually doing some debugging, I guess you can't be certain that a debugger is working.

But you can be pretty sure -- I guess one should assume that if some aspects of xDebug are working then it would all be working.

Given that, you can confirm that xDebug is installed and in place by trying the following:

1) phpinfo() -- this will show you all the extensions that are loaded, including xDebug. If it is there, then it's a safe bet that it's working.

2) If that isn't good enough for you, you can try using the var_dump() function. xDebug modifies the output of var_dump() to include additional information. If this is in place, then xDebug is working.

3) xDebug modifies PHP's error output. If your program crashes with xDebug in place, you'll get more information about the failure than with the standard PHP crash output.

4) xDebug also adds a number of helper functions to PHP. You could try any of these to see if it's working. For example, the function xdebug_get_code_coverage() should exist and return an array. If it does, then xDebug is installed. If not, it isn't.

When saving an array of photos, don't use a for loop, do the following

-(void)saveToAlbum{
   [self performSelectorInBackground:@selector(startSavingToAlbum) withObject:nil];
}
-(void)startSavingToAlbum{
   currentSavingIndex = 0;
   UIImage* img = arrayOfPhoto[currentSavingIndex];//get your image
   UIImageWriteToSavedPhotosAlbum(img, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
}
- (void)image: (UIImage *) image didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo{ //can also handle error message as well
   currentSavingIndex ++;
   if (currentSavingIndex >= arrayOfPhoto.count) {
       return; //notify the user it's done.
   }
   else
   {
       UIImage* img = arrayOfPhoto[currentSavingIndex];
       UIImageWriteToSavedPhotosAlbum(img, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
   }
}

Use onchage function

<input type="radio" name="bedStatus" id="allot" checked="checked" value="allot" onchange="my_function('allot')">Allot
<input type="radio" name="bedStatus" id="transfer" value="transfer" onchange="my_function('transfer')">Transfer

<script>
 function my_function(val){
    alert(val);
 }
</script>

You can access the fields by indexing the object array:

foreach (object[] item in selectedValues)
{
  idTextBox.Text = item[0];
  titleTextBox.Text = item[1];
  contentTextBox.Text = item[2];
}

That said, you'd be better off storing the fields in a small class of your own if the number of items is not dynamic:

public class MyObject
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Content { get; set; }
}

Then you can do:

foreach (MyObject item in selectedValues)
{
  idTextBox.Text = item.Id;
  titleTextBox.Text = item.Title;
  contentTextBox.Text = item.Content;
}

Just give your desired path if file does not exist earlier;

        from os.path import abspath
        with open ('C:\\Users\\Admin\\Desktop\\results.txt', mode = 'w') as final1:
            print(final1.write('This is my new file.'))

        print(f'Text has been processed and saved at {abspath(final1.name)}')

Output will be:

Text has been processed and saved at C:\Users\Admin\Desktop\results.txt

It comes from the era of Line Printers and green-striped fan-fold paper.

Trust me, you ain't gonna need it...

Primary keys always need to be unique, foreign keys need to allow non-unique values if the table is a one-to-many relationship. It is perfectly fine to use a foreign key as the primary key if the table is connected by a one-to-one relationship, not a one-to-many relationship.

A FOREIGN KEY constraint does not have to be linked only to a PRIMARY KEY constraint in another table; it can also be defined to reference the columns of a UNIQUE constraint in another table.

It looks like people are doing the Project Euler thing where you code the solution yourself. For everyone else who wants to get work done, there's the primefac module which does very large numbers very quickly:

#!python

import primefac
import sys

n = int( sys.argv[1] )
factors = list( primefac.primefac(n) )
print '\n'.join(map(str, factors))

We developed an iPad app with XCode 4.2.1 and wanted to integrate the build into our continuous integration (Jenkins) for OTA distribution. Here's the solution I came up with:

# Unlock keychain
security unlock-keychain -p jenkins /Users/jenkins/Library/Keychains/login.keychain

# Build and sign app
xcodebuild -configuration Distribution clean build

# Set variables
APP_PATH="$PWD/build/Distribution-iphoneos/iPadApp.app"
VERSION=`defaults read $APP_PATH/Info CFBundleShortVersionString`
REVISION=`defaults read $APP_PATH/Info CFBundleVersion`
DATE=`date +"%Y%m%d-%H%M%S"`
ITUNES_LINK="<a href=\"itms-services:\/\/?action=download-manifest\&url=https:\/\/xxx.xxx.xxx\/iPadApp-$VERSION.$REVISION-$DATE.plist\">Download iPad2-App v$VERSION.$REVISION-$DATE<\/a>"

# Package and verify app
xcrun -sdk iphoneos PackageApplication -v build/Distribution-iphoneos/iPadApp.app -o $PWD/iPadApp-$VERSION.$REVISION-$DATE.ipa

# Create plist
cat iPadApp.plist.template | sed -e "s/\${VERSION}/$VERSION/" -e "s/\${DATE}/$DATE/" -e "s/\${REVISION}/$REVISION/" > iPadApp-$VERSION.$REVISION-$DATE.plist

# Update index.html
curl https://xxx.xxx.xxx/index.html -o index.html.$DATE
cat index.html.$DATE | sed -n '1h;1!H;${;g;s/\(<h3>Aktuelle Version<\/h3>\)\(.*\)\(<h3>&Auml;ltere Versionen<\/h3>.<ul>.<li>\)/\1\
${ITUNES_LINK}\
\3\2<\/li>\
<li>/g;p;}' | sed -e "s/\${ITUNES_LINK}/$ITUNES_LINK/" > index.html

Then Jenkins uploads the ipa, plist and html files to our webserver.

This is the plist template:

To set this up, you have to import the distribution certificate and provisioning profile into the designated user's keychain.

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.

To position an element, a <table> in your case you want to use either padding or margins.

the difference between margins and paddings can be seen as the "box model":

Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.

I highly recommend the article above if you need to learn how to use CSS.

To move the table down and right I would use margins like so:

table{
    margin:25px 0 0 25px;
}

This is in shorthand so the margins are as follows:

margin: top right bottom left;

All of this works for me:

@Echo Off
Echo Directory = %~dp0
Echo Object Name With Quotations=%0
Echo Object Name Without Quotes=%~0
Echo Bat File Drive = %~d0
Echo Full File Name = %~n0%~x0
Echo File Name Without Extension = %~n0
Echo File Extension = %~x0
Pause>Nul

Output:

Directory = D:\Users\Thejordster135\Desktop\Code\BAT\

Object Name With Quotations="D:\Users\Thejordster135\Desktop\Code\BAT\Path_V2.bat"

Object Name Without Quotes=D:\Users\Thejordster135\Desktop\Code\BAT\Path_V2.bat

Bat File Drive = D:

Full File Name = Path.bat

File Name Without Extension = Path

File Extension = .bat

At first link fontwaesome CSS file in your HTML file then create an after or before pseudo class like "font-family: "FontAwesome"; content: "\f101";" then save. I hope this work good.

Or, for less code, inside your click you place:

setTimeout(function(){ 

$('#DIV_ID').scrollTop(0);

}, 500);

To compare arrays, loop through them and compare every value:

Comparing arrays:

// Warn if overriding existing method
if(Array.prototype.equals)
    console.warn("Overriding existing Array.prototype.equals. Possible causes: New API defines the method, there's a framework conflict or you've got double inclusions in your code.");
// attach the .equals method to Array's prototype to call it on any array
Array.prototype.equals = function (array) {
    // if the other array is a falsy value, return
    if (!array)
        return false;

    // compare lengths - can save a lot of time 
    if (this.length != array.length)
        return false;

    for (var i = 0, l=this.length; i < l; i++) {
        // Check if we have nested arrays
        if (this[i] instanceof Array && array[i] instanceof Array) {
            // recurse into the nested arrays
            if (!this[i].equals(array[i]))
                return false;       
        }           
        else if (this[i] != array[i]) { 
            // Warning - two different object instances will never be equal: {x:20} != {x:20}
            return false;   
        }           
    }       
    return true;
}
// Hide method from for-in loops
Object.defineProperty(Array.prototype, "equals", {enumerable: false});

Usage:

[1, 2, [3, 4]].equals([1, 2, [3, 2]]) === false;
[1, "2,3"].equals([1, 2, 3]) === false;
[1, 2, [3, 4]].equals([1, 2, [3, 4]]) === true;
[1, 2, 1, 2].equals([1, 2, 1, 2]) === true;

You may say "But it is much faster to compare strings - no loops..." well, then you should note there ARE loops. First recursive loop that converts Array to string and second, that compares two strings. So this method is faster than use of string.

_{I believe that larger amounts of data should be always stored in arrays, not in objects. However if you use objects, they can be partially compared too.
Here's how:}

Comparing objects:

I've stated above, that two object instances will never be equal, even if they contain same data at the moment:

({a:1, foo:"bar", numberOfTheBeast: 666}) == ({a:1, foo:"bar", numberOfTheBeast: 666})  //false

This has a reason, since there may be, for example private variables within objects.

However, if you just use object structure to contain data, comparing is still possible:

Object.prototype.equals = function(object2) {
    //For the first loop, we only check for types
    for (propName in this) {
        //Check for inherited methods and properties - like .equals itself
        //https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/hasOwnProperty
        //Return false if the return value is different
        if (this.hasOwnProperty(propName) != object2.hasOwnProperty(propName)) {
            return false;
        }
        //Check instance type
        else if (typeof this[propName] != typeof object2[propName]) {
            //Different types => not equal
            return false;
        }
    }
    //Now a deeper check using other objects property names
    for(propName in object2) {
        //We must check instances anyway, there may be a property that only exists in object2
            //I wonder, if remembering the checked values from the first loop would be faster or not 
        if (this.hasOwnProperty(propName) != object2.hasOwnProperty(propName)) {
            return false;
        }
        else if (typeof this[propName] != typeof object2[propName]) {
            return false;
        }
        //If the property is inherited, do not check any more (it must be equa if both objects inherit it)
        if(!this.hasOwnProperty(propName))
          continue;
        
        //Now the detail check and recursion
        
        //This returns the script back to the array comparing
        /**REQUIRES Array.equals**/
        if (this[propName] instanceof Array && object2[propName] instanceof Array) {
                   // recurse into the nested arrays
           if (!this[propName].equals(object2[propName]))
                        return false;
        }
        else if (this[propName] instanceof Object && object2[propName] instanceof Object) {
                   // recurse into another objects
                   //console.log("Recursing to compare ", this[propName],"with",object2[propName], " both named \""+propName+"\"");
           if (!this[propName].equals(object2[propName]))
                        return false;
        }
        //Normal value comparison for strings and numbers
        else if(this[propName] != object2[propName]) {
           return false;
        }
    }
    //If everything passed, let's say YES
    return true;
}  

However, remember that this one is to serve in comparing JSON like data, not class instances and other stuff. If you want to compare mor complicated objects, look at this answer and it's superlong function.
To make this work with Array.equals you must edit the original function a little bit:

...
    // Check if we have nested arrays
    if (this[i] instanceof Array && array[i] instanceof Array) {
        // recurse into the nested arrays
        if (!this[i].equals(array[i]))
            return false;
    }
    /**REQUIRES OBJECT COMPARE**/
    else if (this[i] instanceof Object && array[i] instanceof Object) {
        // recurse into another objects
        //console.log("Recursing to compare ", this[propName],"with",object2[propName], " both named \""+propName+"\"");
        if (!this[i].equals(array[i]))
            return false;
        }
    else if (this[i] != array[i]) {
...

I made a little test tool for both of the functions.

Bonus: Nested arrays with indexOf and contains

Samy Bencherif has prepared useful functions for the case you're searching for a specific object in nested arrays, which are available here: https://jsfiddle.net/SamyBencherif/8352y6yw/

It looks like you have to set the option for the format with data-date-*. This example works for me with 24h support.

As well as using lapply or some other looping construct in R you could merge your CSV files into one file.

In Unix, if the files had no headers, then its as easy as:

cat *.csv > all.csv

or if there are headers, and you can find a string that matches headers and only headers (ie suppose header lines all start with "Age"), you'd do:

cat *.csv | grep -v ^Age > all.csv

I think in Windows you could do this with COPY and SEARCH (or FIND or something) from the DOS command box, but why not install cygwin and get the power of the Unix command shell?

You need to wrap all the html into one single element.

<template>
   <div>
        <div class="form-group">
            <label for="avatar" class="control-label">Avatar</label>
            <input type="file" v-on:change="fileChange" id="avatar">
            <div class="help-block">
                Help block here updated 4  ...
            </div>
        </div>

        <div class="col-md-6">
            <input type="hidden" name="avatar_id">
            <img class="avatar" title="Current avatar">
        </div>
   </div>

</template>

<script>
    export default{
        methods: {
            fileChange(){
                console.log('Test of file input change')
            }
        }
    }
</script>

The variable '$$' contains the PID.

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);

Don't export **default** class MyComponentComponent!

Related issue that might fall under the title, if not the specific question:

I accidentally did a...

export default class MyComponentComponent {

... and that screwed things up too.

Why? VS Code added the import to my module when I put it into declarations, but instead of...

import { MyComponentComponent } from '...';

it had

import MyComponentComponent from '...';

And that didn't map up downstream, assumedly since it wasn't "really" named anywhere with the default import.

export class MyComponentComponent {

No default. Profit.

Omit the double quotes from your first query.

... LIKE '%\n%' 

I cannot find such an option either, at least in the Community edition.

I suppose this corresponds to the Reverse Engineering feature, which, unfortunately, is only available in the commercial edition (quoting) :

reverse engineering a database directly from a MySQL server applies to commercial versions of MySQL Workbench only.

Still, you can use plain-SQL to get the create table instruction that will allow you to create a table.

For instance, the following query :

show create table url_alias;

when executed on a drupal database, would give, when using right click > copy field content on the result :

'CREATE TABLE `url_alias` (
  `pid` int(10) unsigned NOT NULL auto_increment,
  `src` varchar(128) NOT NULL default '''',
  `dst` varchar(128) NOT NULL default '''',
  `language` varchar(12) NOT NULL default '''',
  PRIMARY KEY  (`pid`),
  UNIQUE KEY `dst_language` (`dst`,`language`),
  KEY `src_language` (`src`,`language`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8'

Unfortunately (again), MySQL Workbench adds some quotes everywhere when copying this way :-(

EDIT: Using MySQL 8.0, there is an option to right click > copy field (unquoted) on the result to get the desired result without quotes.

In the end, the simplest solution, except from staying with MySQL Query Browser, will most likely be to connect to the database, using the command-line client, and execute the show create table query from there :

mysql> show create table url_alias\G
*************************** 1. row ***************************
       Table: url_alias
Create Table: CREATE TABLE `url_alias` (
  `pid` int(10) unsigned NOT NULL auto_increment,
  `src` varchar(128) NOT NULL default '',
  `dst` varchar(128) NOT NULL default '',
  `language` varchar(12) NOT NULL default '',
  PRIMARY KEY  (`pid`),
  UNIQUE KEY `dst_language` (`dst`,`language`),
  KEY `src_language` (`src`,`language`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8
1 row in set (0.00 sec)

Getting "the right portion" of the output is easier, there : no quote to remove.

And, just for the sake of completness, you could also use mysqldump to get your table's structure :

mysqldump --no-data --user=USERNAME --password=PASSWORD --host=HOST DATABASE_NAME TABLE_NAME

Using the --no-data switch, you'll only get the structure -- in the middle of some mode settings and all that.

If you see table class it has border-spacing: 2px; You could override table class in your css and set its border-spacing: 0px!important in table; I did it like

table {
      border-collapse: separate;
      white-space: normal;
      line-height: normal;
      font-weight: normal;
      font-size: medium;
      font-style: normal;
      color: -internal-quirk-inherit;
      text-align: start;
      border-spacing: 0px!important;
      font-variant: normal;   }

It saved my day.Hope it would be of help. Thanks.

Click in the grid so it has focus.

Ctrl+End

This will force the rest of the records back into the grid.

You should use double slash:

var regex = new RegExp("\\?", "g");

Why? because in JavaScript the \ is also used to escape characters in strings, so: "\?" becomes: "?"

And "\\?", becomes "\?"

if (StartDate>=EndDate)
{
    throw new InvalidOperationException("Ack!  StartDate is not before EndDate!");
}

This confused me for a while until I worked out that the dependencies of the various projects in the solution had been messed up. Get that straight and naturally your assembly appears in the right place.

Does replacing a character in a String with a null character even work in Java? I know that '\0' will terminate a c-string.

That depends on how you define what is working. Does it replace all occurrences of the target character with '\0'? Absolutely!

String s = "food".replace('o', '\0');
System.out.println(s.indexOf('\0')); // "1"
System.out.println(s.indexOf('d')); // "3"
System.out.println(s.length()); // "4"
System.out.println(s.hashCode() == 'f'*31*31*31 + 'd'); // "true"

Everything seems to work fine to me! indexOf can find it, it counts as part of the length, and its value for hash code calculation is 0; everything is as specified by the JLS/API.

It DOESN'T work if you expect replacing a character with the null character would somehow remove that character from the string. Of course it doesn't work like that. A null character is still a character!

String s = Character.toString('\0');
System.out.println(s.length()); // "1"
assert s.charAt(0) == 0;

It also DOESN'T work if you expect the null character to terminate a string. It's evident from the snippets above, but it's also clearly specified in JLS (10.9. An Array of Characters is Not a String):

In the Java programming language, unlike C, an array of char is not a String, and neither a String nor an array of char is terminated by '\u0000' (the NUL character).

Would this be the culprit to the funky characters?

Now we're talking about an entirely different thing, i.e. how the string is rendered on screen. Truth is, even "Hello world!" will look funky if you use dingbats font. A unicode string may look funky in one locale but not the other. Even a properly rendered unicode string containing, say, Chinese characters, may still look funky to someone from, say, Greenland.

That said, the null character probably will look funky regardless; usually it's not a character that you want to display. That said, since null character is not the string terminator, Java is more than capable of handling it one way or another.

Now to address what we assume is the intended effect, i.e. remove all period from a string, the simplest solution is to use the replace(CharSequence, CharSequence) overload.

System.out.println("A.E.I.O.U".replace(".", "")); // AEIOU

The replaceAll solution is mentioned here too, but that works with regular expression, which is why you need to escape the dot meta character, and is likely to be slower.

When I need to chain calls like that, I rely on a helper method I created, TryGet():

    public static U TryGet<T, U>(this T obj, Func<T, U> func)
    {
        return obj.TryGet(func, default(U));
    }

    public static U TryGet<T, U>(this T obj, Func<T, U> func, U whenNull)
    {
        return obj == null ? whenNull : func(obj);
    }

In your case, you would use it like so:

    int value = ObjectA
        .TryGet(p => p.PropertyA)
        .TryGet(p => p.PropertyB)
        .TryGet(p => p.PropertyC, defaultVal);

If your list of words is of substantial length, and you need to do this test many times, it may be worth converting the list to a set and using set intersection to test (with the added benefit that you wil get the actual words that are in both lists):

>>> long_word_list = 'some one long two phrase three about above along after against'
>>> long_word_set = set(long_word_list.split())
>>> set('word along river'.split()) & long_word_set
set(['along'])

just add using System.Linq and see the magic happening when you try to access the available methods in the IEnumerable. Adding this will give you access to method named Count() as simple as that. just remember to check for null value before calling count() :)

For some reason, a question about GET requests was merged with this one, so I'll respond to it here.

This simple function will asynchronously get an HTTP status reply from a CORS-enabled page. If you run it, you'll see that only a page with the proper headers returns a 200 status if accessed via XMLHttpRequest -- whether GET or POST is used. Nothing can be done on the client side to get around this except possibly using JSONP if you just need a json object.

The following can be easily modified to get the data held in the xmlHttpRequestObject object:

function checkCorsSource(source) {_x000D_
  var xmlHttpRequestObject;_x000D_
  if (window.XMLHttpRequest) {_x000D_
    xmlHttpRequestObject = new XMLHttpRequest();_x000D_
    if (xmlHttpRequestObject != null) {_x000D_
      var sUrl = "";_x000D_
      if (source == "google") {_x000D_
        var sUrl = "https://www.google.com";_x000D_
      } else {_x000D_
        var sUrl = "https://httpbin.org/get";_x000D_
      }_x000D_
      document.getElementById("txt1").innerHTML = "Request Sent...";_x000D_
      xmlHttpRequestObject.open("GET", sUrl, true);_x000D_
      xmlHttpRequestObject.onreadystatechange = function() {_x000D_
        if (xmlHttpRequestObject.readyState == 4 && xmlHttpRequestObject.status == 200) {_x000D_
          document.getElementById("txt1").innerHTML = "200 Response received!";_x000D_
        } else {_x000D_
          document.getElementById("txt1").innerHTML = "200 Response failed!";_x000D_
        }_x000D_
      }_x000D_
      xmlHttpRequestObject.send();_x000D_
    } else {_x000D_
      window.alert("Error creating XmlHttpRequest object. Client is not CORS enabled");_x000D_
    }_x000D_
  }_x000D_
}

Much of the Answer here seems to be hacks to the shape drawable, while android in itself supports this with the shapes functionality. This is something that worked perfectly for me.You can do this in two ways

Using a fixed height and width, that would stay the same regardless of the text that you put it as shown below

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">

<solid android:color="@color/alpha_white" />

    <size android:width="25dp" android:height="25dp"/>

<stroke android:color="@color/color_primary" android:width="1dp"/>

</shape>

Using Padding which re-adjusts the shape regardless of the text in the textview it as shown below

<solid android:color="@color/alpha_white" />

<padding
    android:bottom="@dimen/semi_standard_margin"
    android:left="@dimen/semi_standard_margin"
    android:right="@dimen/semi_standard_margin"
    android:top="@dimen/semi_standard_margin" />

<stroke android:color="@color/color_primary" android:width="2dp"/>

semi_standard_margin = 4dp

The first is the original for loop. You initialize a variable, set a terminating condition, and provide a state incrementing/decrementing counter (There are exceptions, but this is the classic)

For that,

for (int i=0;i<myString.length;i++) { 
  System.out.println(myString[i]); 
}

is correct.

For Java 5 an alternative was proposed. Any thing that implements iterable can be supported. This is particularly nice in Collections. For example you can iterate the list like this

List<String> list = ....load up with stuff

for (String string : list) {
  System.out.println(string);
}

instead of

for (int i=0; i<list.size();i++) {
  System.out.println(list.get(i));
}

So it's just an alternative notation really. Any item that implements Iterable (i.e. can return an iterator) can be written that way.

What's happening behind the scenes is somethig like this: (more efficient, but I'm writing it explicitly)

Iterator<String> it = list.iterator();
while (it.hasNext()) {
  String string=it.next();
  System.out.println(string);
}

In the end it's just syntactic sugar, but rather convenient.

This error occurs because the transaction log becomes full due to LOG_BACKUP. Therefore, you can’t perform any action on this database, and In this case, the SQL Server Database Engine will raise a 9002 error.

To solve this issue you should do the following

• Take a Full database backup.
• Shrink the log file to reduce the physical file size.
• Create a LOG_BACKUP.
• Create a LOG_BACKUP Maintenance Plan to take backup logs frequently.

I wrote an article with all details regarding this error and how to solve it at The transaction log for database ‘SharePoint_Config’ is full due to LOG_BACKUP

Really great advise, except that the SAME error CAN occur simply by missing the critical script include on your root page

example:

page: index.html

   np-app="saleApp"

Missing

<script src="./ordersController.js"></script>

When a Route is told what controller and view to serve up:

 .when('/orders/:customerId', {
     controller: 'OrdersController',
     templateUrl: 'views/orders.html'
 })

So essential the undefined controller issue CAN occur in this accidental mistake of not even referencing the controller!

<div style="position: absolute; overflow: hidden; left: 0px; top: 0px; border: solid 2px #555; width:594px; height:332px;">
<div style="overflow: hidden; margin-top: -100px; margin-left: -25px;">
</div>
<iframe src="http://example.com/" scrolling="no" style="height: 490px; border: 0px none; width: 619px; margin-top: -60px; margin-left: -24px; ">
</iframe>

I had a similar issue that I couldn't find the answer to. A few Google searches later led me here. Considering I didn't find the simple answer I was hoping for, I stumbled upon a solution that is both elegant and effective.

It turns out the visibility CSS property has a value collapse which is generally used for table items. However, if used on any other elements it effectively renders them as hidden, pretty much the same as display: hidden but with the added ability that the element doesn't take up any space and you can still animate the element in question.

Below is a simple example of this in action.

function toggleVisibility() {_x000D_
  let exampleElement = document.querySelector('span');_x000D_
  if (exampleElement.classList.contains('visible')) {_x000D_
    return;_x000D_
  }_x000D_
  exampleElement.innerHTML = 'I will not take up space!';_x000D_
  exampleElement.classList.toggle('hidden');_x000D_
  exampleElement.classList.toggle('visible');_x000D_
  setTimeout(() => {_x000D_
    exampleElement.classList.toggle('visible');_x000D_
    exampleElement.classList.toggle('hidden');_x000D_
  }, 3000);_x000D_
}

#main {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  width: 300px;_x000D_
  text-align: center;_x000D_
}_x000D_
_x000D_
.hidden {_x000D_
  visibility: collapse;_x000D_
  opacity: 0;_x000D_
  transition: visibility 2s, opacity 2s linear;_x000D_
}_x000D_
_x000D_
.visible {_x000D_
  visibility: visible;_x000D_
  opacity: 1;_x000D_
  transition: visibility 0.5s, opacity 0.5s linear;_x000D_
}

<div id="main">_x000D_
  <button onclick="toggleVisibility()">Click Me!</button>_x000D_
  <span class="hidden"></span>_x000D_
  <span>I will get pushed back up...</span>_x000D_
</div>

You can do it without a directive but i'm not sure it's the best way. To do this you must create array of array from the data you want to display in the table, and after that use 2 ng-repeat to iterate through the array.

to create the array for display use this function like that products.chunk(3)

Array.prototype.chunk = function(chunkSize) {
    var array=this;
    return [].concat.apply([],
        array.map(function(elem,i) {
            return i%chunkSize ? [] : [array.slice(i,i+chunkSize)];
        })
    );
}

and then do something like that using 2 ng-repeat

<div class="row" ng-repeat="row in products.chunk(3)">
  <div class="col-sm4" ng-repeat="item in row">
    {{item}}
  </div>
</div>

The response itself seems to have the size of the records. You can use that to check if records exist. Something like:

if($response->size > 0){
    $role_arr = getRole($response->records);
}

Here's an interesting website that explains how to read complex types in C: http://www.unixwiz.net/techtips/reading-cdecl.html

Sure: svn rm the unwanted folder, and commit.

To avoid this situation in the future, I would follow the recommended layout for SVN projects:

• Put your code in the /someproject/trunk folder (or just /trunk if you want to put only one project in the repository)
• Created branches as /someproject/branches/somebranch
• Put tags under /someproject/tags

Now when you check out a working copy, be sure to check out only trunk or some individual branch. Don't check everything out in one huge working copy containing all branches.¹

¹_{Unless you know what you're doing, in which case you know how to create shallow working copies.}

For this particular problem, why not store up your various results in variables and then when the last of your thread is processed you can print in whatever format you want. This is especially useful if you are gonna be using your work history in other projects.

This is somewhat of an extension to the answer when the comment line is too long to fit on a line (above 80 chars or whatever). If the comment is too long and text needs to wrap, it's better to keep it under control (rather than use the editor's text wrap feature). This plugin Rewrap helps do just that https://marketplace.visualstudio.com/items?itemName=stkb.rewrap&ssr=false#review-details

Install the plugin in VS Code, select the text comment, comment it using one of the right methods described in the answers (Ctrl + / is easiest) and then once it's commented, press Alt + Q and this will split the text to multiple lines and also comment it. Found it pretty useful. Hope this helps someone :)

If you know exactly which frames to extract, eg 1, 200, 400, 600, 800, 1000, try using:

select='eq(n\,1)+eq(n\,200)+eq(n\,400)+eq(n\,600)+eq(n\,800)+eq(n\,1000)' \
       -vsync vfr -q:v 2

I'm using this with a pipe to Imagemagick's montage to get 10 frames preview from any videos. Obviously the frame numbers you'll need to figure out using ffprobe

ffmpeg -i myVideo.mov -vf \
    select='eq(n\,1)+eq(n\,200)+eq(n\,400)+eq(n\,600)+eq(n\,800)+eq(n\,1000)',scale=320:-1 \
    -vsync vfr -q:v 2 -f image2pipe -vcodec ppm - \
  | montage -tile x1 -geometry "1x1+0+0<" -quality 100 -frame 1 - output.png

.

Little explanation:

1. In ffmpeg expressions + stands for OR and * for AND
2. \, is simply escaping the , character
3. Without -vsync vfr -q:v 2 it doesn't seem to work but I don't know why - anyone?

Generally you can do

select * from your_table
order by case when name = 'core' then 1 else 2 end,
         priority 

Especially in MySQL you can also do

select * from your_table
order by name <> 'core',
         priority 

Since the result of a comparision in MySQL is either 0 or 1 and you can sort by that result.

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:
              break

• "Restart" is also deprecated. You can use restart under deploy with on-failure action
• You can use a standalone one node "swarm", v3 most improvements (if not all) are for swarm

Also Note: Networks in Swarm mode do not bridge. If you would like to connect internally only, you have to attach to the network. You can 1) specify an external network within an other compose file, or have to create the network with --attachable parameter (docker network create -d overlay My-Network --attachable) Otherwise you have to publish the port like this:

ports:

You can use:

CurrentDb.Execute "ALTER TABLE yourTable ALTER COLUMN myID COUNTER(1,1)"

I hope you have no relationships that use this table, I hope it is empty, and I hope you understand that all you can (mostly) rely on an autonumber to be is unique. You can get gaps, jumps, very large or even negative numbers, depending on the circumstances. If your autonumber means something, you have a major problem waiting to happen.

You can use the mounted() Vue Lifecycle Hook. This will allow you to call a method before the page loads.

This is an implementation example:

HTML:

<div id="app">
  <h1>Welcome our site {{ name }}</h1>
</div>

JS:

var app = new Vue ({
    el: '#app',
    data: {
        name: ''
    },
    mounted: function() {
        this.askName() // Calls the method before page loads
    },
    methods: {
        // Declares the method
        askName: function(){
            this.name = prompt(`What's your name?`)
        }
    }
})

This will get the prompt method's value, insert it in the variable name and output in the DOM after the page loads. You can check the code sample here.

You can read more about Lifecycle Hooks here.

If you don't/can't keep the connection open you could use screen, if you have the rights to install it.

user@localhost $ screen -t remote-command
user@localhost $ ssh user@target # now inside of a screen session
user@remotehost $ cd /some/directory; program-to-execute &

To detach the screen session: ctrl-a d

To list screen sessions:

screen -ls

To reattach a session:

screen -d -r remote-command

Note that screen can also create multiple shells within each session. A similar effect can be achieved with tmux.

user@localhost $ tmux
user@localhost $ ssh user@target # now inside of a tmux session
user@remotehost $ cd /some/directory; program-to-execute &

To detach the tmux session: ctrl-b d

To list screen sessions:

tmux list-sessions

To reattach a session:

tmux attach <session number>

The default tmux control key, 'ctrl-b', is somewhat difficult to use but there are several example tmux configs that ship with tmux that you can try.

So notice variables are on the stack, the values they refer to are on the heap. So having variables is not too bad but yes they do create references to other entities. However in the simple case you describe it's not really any consequence. If it is never read again and within a contained scope, the compiler will probably strip it out before runtime. Even if it didn't the garbage collector will be able to safely remove it after the stack squashes. If you are running into issues where you have too many stack variables, it's usually because you have really deep stacks. The amount of stack space needed per thread is a better place to adjust than to make your code unreadable. The setting to null is also no longer needed

Maybe you have no Comments record with such primary key, then you should use this code:

try:
    comment = Comment.objects.get(pk=comment_id)
except Comment.DoesNotExist:
    comment = None

You can do:

var buf = Buffer.from(bufStr, 'utf8');

But this is a bit silly, so another suggestion would be to copy the minimal amount of code out of the called function to allow yourself access to the original buffer. This might be quite easy or fairly difficult depending on the details of that library.

No need for mysqladmin:

just use mysql command line

mysql -u [username] -p[password] -e 'drop database db-name;'

This will send the drop command although I wouldn't pass the password this way as it'll be exposed to other users of the system via ps aux

The difference can be illustrated by the following:

std::cout << std::endl;

is equivalent to

std::cout << '\n' << std::flush;

So,

• Use std::endl If you want to force an immediate flush to the output.
• Use \n if you are worried about performance (which is probably not the case if you are using the << operator).

I use \n on most lines.
Then use std::endl at the end of a paragraph (but that is just a habit and not usually necessary).

Contrary to other claims, the \n character is mapped to the correct platform end of line sequence only if the stream is going to a file (std::cin and std::cout being special but still files (or file-like)).
