Something like this

SELECT * 
FROM MyParts 
LEFT JOIN 
(
SELECT MAX(PriceDate), PartID FROM MyPrice group by PartID
) myprice
 ON MyParts.Partid = MyPrice.Partid 

If you know your partid or can restrict it put it inside the join.

   SELECT myprice.partid, myprice.partdate, myprice2.Price, * 
    FROM MyParts 
    LEFT JOIN 
    (
    SELECT MAX(PriceDate), PartID FROM MyPrice group by PartID
    ) myprice
     ON MyParts.Partid = MyPrice.Partid 
    Inner Join MyPrice myprice2
    on myprice2.pricedate = myprice.pricedate
    and myprice2.partid = myprice.partid

The Pumping lemma for regular languages is the reason why you can't do that.

The generated automaton will have a finite number of states, say k, so a string of k+1 opening braces is bound to have a state repeated somewhere (as the automaton processes the characters). The part of the string between the same state can be duplicated infinitely many times and the automaton will not know the difference.

In particular, if it accepts k+1 opening braces followed by k+1 closing braces (which it should) it will also accept the pumped number of opening braces followed by unchanged k+1 closing brases (which it shouldn't).

You would need to use Javascript for this. You can set the style of the background-image for the body like so.

var body = document.getElementsByTagName('body')[0];
body.style.backgroundImage = 'url(http://localhost/background.png)';

Just make sure you replace the URL with the actual URL.

Loop through the dictionary to find the index and then remove it.

Cecil Curry has a great answer, however his answer only works for multiline regular expressions. Multiline regular expressions are more rarely used, but they are handy sometimes.

Here is an improvement upon his sed_inplace function that allows it to function with multiline regular expressions if asked to do so.

WARNING: In multiline mode, it will read the entire file in, and then perform the regular expression substitution, so you'll only want to use this mode on small-ish files - don't try to run this on gigabyte-sized files when running in multiline mode.

import re, shutil, tempfile

def sed_inplace(filename, pattern, repl, multiline = False):
    '''
    Perform the pure-Python equivalent of in-place `sed` substitution: e.g.,
    `sed -i -e 's/'${pattern}'/'${repl}' "${filename}"`.
    '''
    re_flags = 0
    if multiline:
        re_flags = re.M

    # For efficiency, precompile the passed regular expression.
    pattern_compiled = re.compile(pattern, re_flags)

    # For portability, NamedTemporaryFile() defaults to mode "w+b" (i.e., binary
    # writing with updating). This is usually a good thing. In this case,
    # however, binary writing imposes non-trivial encoding constraints trivially
    # resolved by switching to text writing. Let's do that.
    with tempfile.NamedTemporaryFile(mode='w', delete=False) as tmp_file:
        with open(filename) as src_file:
            if multiline:
                content = src_file.read()
                tmp_file.write(pattern_compiled.sub(repl, content))
            else:
                for line in src_file:
                    tmp_file.write(pattern_compiled.sub(repl, line))

    # Overwrite the original file with the munged temporary file in a
    # manner preserving file attributes (e.g., permissions).
    shutil.copystat(filename, tmp_file.name)
    shutil.move(tmp_file.name, filename)

from os.path import expanduser
sed_inplace('%s/.gitconfig' % expanduser("~"), r'^(\[user\]$\n[ \t]*name = ).*$(\n[ \t]*email = ).*', r'\1John Doe\[email protected]', multiline=True)

I modified @FrinkTheBrave 's answer to also create sub-directories, and resolve relative paths:

$src_root = Resolve-Path("./source/path/")
$target_root = Resolve-Path("./target/path/")
$glob_filter = "*.*"
Get-ChildItem -path $src_root -filter $glob_filter -recurse | 
  ForEach-Object {
        $target_filename=($_.FullName -replace [regex]::escape($src_root),$target_root) 
        $target_path=Split-Path $target_filename
        if (!(Test-Path -Path $target_path)) {
            New-Item $target_path -ItemType Directory
        }
        Copy-Item $_.FullName -destination $target_filename
    }

How about extending a jquery for this?

   (function () {
        var ev = new $.Event('remove'),
            orig = $.fn.remove;
        var evap = new $.Event('append'),
           origap = $.fn.append;
        $.fn.remove = function () {
            $(this).trigger(ev);
            return orig.apply(this, arguments);
        }
        $.fn.append = function () {
            $(this).trigger(evap);
            return origap.apply(this, arguments);
        }
    })();
    $(document).on('append', function (e) { /*write your logic here*/ });
    $(document).on('remove', function (e) { /*write your logic here*/ });

Jquery 1.9+ has built support for this(I have heard not tested).

Please, see oficial encode() and decode() documentation from codecs library. utf-8 is the default encoding for the functions, but there are severals standard encodings in Python 3, like latin_1 or utf_32.

$ adb shell pm dump PACKAGE_NAME | grep -A 1 MAIN

Or with standard Java API you can use java.util.Properties:

Properties props = new Properties();
try (FileInputStream in = new FileInputStream(path)) {
    props.load(in);
}

An easy way to the fix the problem, sans coding, is to use Photoshop's Save for Web export function. In the dialog box one can chose to remove all or most of an image's EXIF data. I usually just keep copyright and contact info. Also, since images coming directly from a digital camera are greatly oversized for web display it is a good idea to downsize them via Save for the Web anyway. For those that are not Photoshop savvy, I have no doubt that there are online resources for resizing an image and stripping it of any unnecessary EXIF data.

Both values can be easily distinguished by using the strict comparison operator:

Working example at:

http://www.thesstech.com/tryme?filename=nullandundefined

Sample Code:

function compare(){
    var a = null; //variable assigned null value
    var b;  // undefined
    if (a === b){
        document.write("a and b have same datatype.");
    }
    else{
        document.write("a and b have different datatype.");
    }   
}

Well, depending on your needs you can choose any of the following. Out put is written against each method

You can choose the one you need

This will round

decimal d = 2.5789m;
Console.WriteLine(d.ToString("#.##")); // 2.58

This will ensure that 2 decimal places are written.

d = 2.5m;
Console.WriteLine(d.ToString("F")); //2.50

if you want to write commas you can use this

d=23545789.5432m;
Console.WriteLine(d.ToString("n2")); //23,545,789.54

if you want to return the rounded of decimal value you can do this

d = 2.578m;
d = decimal.Round(d, 2, MidpointRounding.AwayFromZero); //2.58

As other answers have pointed out, the problem is because of line-end auto correcting. I encountered this issue with *.svg files. I used svg file for icons in my project.

To solve this issue, I let git know that svg files should be treated as binary instead of text by adding the below line to .gitattributes

*.svg binary

I would say that you should only expect users to have a monitor with 800x600 resolution. The Canadian government has standards that list this as one of the requirements. Although that may seem low to somebody with a fancy widescreen monitor, remember that not everybody has a nice monitor. I still know a lot of people running at 1024x768. And it's not at all uncommon to run into someone who's running in 800x600, especially in cheap web cafes while travelling. Also, it's nice to have to make your browser window full screen if you don't want to. You can make the site wider on wider monitors, but don't make the user scroll horizontally. Ever. Another advantage of supporting lower resolutions is that your site will work on mobile phones and Nintendo Wii's a lot easier.

A note on your at least 1280 wide, I would have to say that's way overboard. Most 17 and even my 19 inch non widescreen monitors only support a maximum resolution of 1280x1024. And the 14 inch widescreen laptop I'm typing on right now is only 1280 pixels across. I would say that the largest minimum resolution you should strive for is 1024x768, but 800x600 would be ideal.

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

If you are running windows 7 (professional) and Git for Windows (v 2.15 or above), you can simply run below command to find out what are different diff tools supported by your Git for Windows

git difftool --tool-help

You will see output similar to this

git difftool --tool=' may be set to one of the following:
vimdiff vimdiff2 vimdiff3

it means that your git does not support(can not find) beyond compare as difftool right now.

In order for Git to find beyond compare as valid difftool, you should have Beyond Compare installation directory in your system path environment variable. You can check this by running bcompare from shell(cmd, git bash or powershell. I am using Git Bash). If Beyond Compare does not launch, add its installation directory (in my case, C:\Program Files\Beyond Compare 4) to your system path variable. After this, restart your shell. Git will show Beyond Compare as possible difftool option. You can use any of below commands to launch beyond compare as difftool (for example, to compare any local file with some other branch)

git difftool -t bc branchnametocomparewith -- path-to-file
or 
git difftool --tool=bc branchnametocomparewith -- path-to-file

You can configure beyond compare as default difftool using below commands

   git config --global diff.tool bc

p.s. keep in mind that bc in above command can be bc3 or bc based upon what Git was able to find from your path system variable.

Just wanted to add to Abizern answer. If anyone is using a non-administrator account, you can create a "local" variable instead of a "system" variable which allows access to standard/limited accounts.

When on the "Environmental Variables" window:

1) Select "New..." button within the "User variables for ..." section.

2) Set the "Variable name:" as "path" and "Variable value:" as "[your-git-path]" (usually found at C:\Program Files (x86)\Git\bin).

3) Then click OK.

There is also a difference in indexing.

interface MyInterface {
  foobar: string;
}

type MyType = {
  foobar: string;
}

const exampleInterface: MyInterface = { foobar: 'hello world' };
const exampleType: MyType = { foobar: 'hello world' };

let record: Record<string, string> = {};

record = exampleType;      // Compiles
record = exampleInterface; // Index signature is missing

So please consider this example, if you want to index your object

Take a look on this question

Accepted answer is great, just know that if you are sending a DateTime2 to the frontend - it gets rounded to the normal DateTime equivalent.

This caused a problem for me because in a solution of mine I had to compare what was sent with what was on the database when resubmitted, and my simple comparison '==' didn't allow for rounding. So it had to be added.

type is actually a metaclass -- a class that creates another classes. Most metaclass are the subclasses of type. The metaclass receives the new class as its first argument and provide access to class object with details as mentioned below:

>>> class MetaClass(type):
...     def __init__(cls, name, bases, attrs):
...         print ('class name: %s' %name )
...         print ('Defining class %s' %cls)
...         print('Bases %s: ' %bases)
...         print('Attributes')
...         for (name, value) in attrs.items():
...             print ('%s :%r' %(name, value))
... 

>>> class NewClass(object, metaclass=MetaClass):
...    get_choch='dairy'
... 
class name: NewClass
Bases <class 'object'>: 
Defining class <class 'NewClass'>
get_choch :'dairy'
__module__ :'builtins'
__qualname__ :'NewClass'

Note:

Notice that the class was not instantiated at any time; the simple act of creating the class triggered execution of the metaclass.

The Default Expiration Period for Session is 20 Minutes.

You can update sessionstate and configure the minutes under timeout

<sessionState 
timeout="30">
</sessionState>

Just for completeness I would like to add my solution. I ended up doing this with the standard ed:

ed -s sometextfile <<< $'-2,$d\nwq'

This deletes the last 2 lines using in-place editing (although it does use a temporary file in /tmp !!)

In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.

It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.

As a note for the future: if you need a sentence parsed out and tag it as linguistics (and syntax or whatnot, if that's available), someone can probably parse it out for you and guide you through it.

This answer is backing up litb in your comments. I have profound suspicions you are just not displaying the result properly.

I had the exact same thing happen to me once. I spent a whole day trying to figure out why I was getting a bad value into a 64-bit int, only to discover that printf was ignoring the second byte. You can't just pass a 64-bit value into printf like its an int.

It worked i used userdell --force USERNAME Some times eventhough -f and --force is same -f is not working sometimes After i removed the account i exit back to that removed username which i removed from root then what happened is this

You'll want something like this:

$("#next").click(function(){
      var currentElement = currentElement.next();
      $('html, body').animate({scrollLeft: $(currentElement).offset().left}, 800);
      return false;
   }); 

Here's a directive that will add target="_blank" to all <a> tags with an href attribute. That means they will all open in a new window. Remember that directives are used in Angular for any dom manipulation/behavior. Live demo (click).

app.directive('href', function() {
  return {
    compile: function(element) {
      element.attr('target', '_blank');
    }
  };
});

Here's the same concept made less invasive (so it won't affect all links) and more adaptable. You can use it on a parent element to have it affect all children links. Live demo (click).

app.directive('targetBlank', function() {
  return {
    compile: function(element) {
      var elems = (element.prop("tagName") === 'A') ? element : element.find('a');
      elems.attr("target", "_blank");
    }
  };
});

Old Answer

It seems like you would just use "target="_blank" on your <a> tag. Here are two ways to go:

<a href="//facebook.com" target="_blank">Facebook</a>
<button ng-click="foo()">Facebook</button>

JavaScript:

var app = angular.module('myApp', []);

app.controller('myCtrl', function($scope, $window) {
  $scope.foo = function() {
    $window.open('//facebook.com');
  };
});

Live demo here (click).

Here are the docs for $window: http://docs.angularjs.org/api/ng.$window

You could just use window, but it is better to use dependency injection, passing in angular's $window for testing purposes.

The warning comes from the fact that you're dereferencing src in the assignment. The expression *src has type char, which is an integral type. The expression "anotherstring" has type char [14], which in this particular context is implicitly converted to type char *, and its value is the address of the first character in the array. So, you wind up trying to assign a pointer value to an integral type, hence the warning. Drop the * from *src, and it should work as expected:

src = "anotherstring";

since the type of src is char *.

Just add this function and call it, it will convert List to DataTable.

public static DataTable ToDataTable<T>(List<T> items)
{
        DataTable dataTable = new DataTable(typeof(T).Name);

        //Get all the properties
        PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
        foreach (PropertyInfo prop in Props)
        {
            //Defining type of data column gives proper data table 
            var type = (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) ? Nullable.GetUnderlyingType(prop.PropertyType) : prop.PropertyType);
            //Setting column names as Property names
            dataTable.Columns.Add(prop.Name, type);
        }
        foreach (T item in items)
        {
           var values = new object[Props.Length];
           for (int i = 0; i < Props.Length; i++)
           {
                //inserting property values to datatable rows
                values[i] = Props[i].GetValue(item, null);
           }
           dataTable.Rows.Add(values);
      }
      //put a breakpoint here and check datatable
      return dataTable;
}

Late, but relevant to request and hopefully helpful. If using an external service (as suggested in the reply by CommonsWare) then Docmosis has a cloud service that might help - offloading processing to a cloud service that does the heavy processing. That approach is ideal in some circumstances but of course relies on being net-connected.

As mentioned in the comments, the Starting Guide is the place to start with Java 11 and JavaFX 11.

The key to work as you did before Java 11 is to understand that:

• JavaFX 11 is not part of the JDK anymore
• You can get it in different flavors, either as an SDK or as regular dependencies (maven/gradle).
• You will need to include it to the module path of your project, even if your project is not modular.

JavaFX project

If you create a regular JavaFX default project in IntelliJ (without Maven or Gradle) I'd suggest you download the SDK from here. Note that there are jmods as well, but for a non modular project the SDK is preferred.

These are the easy steps to run the default project:

1. Create a JavaFX project
2. Set JDK 11 (point to your local Java 11 version)
3. Add the JavaFX 11 SDK as a library. The URL could be something like /Users/<user>/Downloads/javafx-sdk-11/lib/. Once you do this you will notice that the JavaFX classes are now recognized in the editor.

4. Before you run the default project, you just need to add these to the VM options:

   --module-path /Users/<user>/Downloads/javafx-sdk-11/lib --add-modules=javafx.controls,javafx.fxml

5. Run

Maven

If you use Maven to build your project, follow these steps:

1. Create a Maven project with JavaFX archetype
2. Set JDK 11 (point to your local Java 11 version)

3. Add the JavaFX 11 dependencies.

   <dependencies>
       <dependency>
           <groupId>org.openjfx</groupId>
           <artifactId>javafx-controls</artifactId>
           <version>11</version>
       </dependency>
       <dependency>
           <groupId>org.openjfx</groupId>
           <artifactId>javafx-fxml</artifactId>
           <version>11</version>
       </dependency>
   </dependencies>
   

Once you do this you will notice that the JavaFX classes are now recognized in the editor.

You will notice that Maven manages the required dependencies for you: it will add javafx.base and javafx.graphics for javafx.controls, but most important, it will add the required classifier based on your platform. In my case, Mac.

This is why your jars org.openjfx:javafx-controls:11 are empty, because there are three possible classifiers (windows, linux and mac platforms), that contain all the classes and the native implementation.

In case you still want to go to your .m2 repo and take the dependencies from there manually, make sure you pick the right one (for instance .m2/repository/org/openjfx/javafx-controls/11/javafx-controls-11-mac.jar)

4. Replace default maven plugins with those from here.

5. Run mvn compile javafx:run, and it should work.

Similar works as well for Gradle projects, as explained in detail here.

EDIT

The mentioned Getting Started guide contains updated documentation and sample projects for IntelliJ:

• JavaFX 11 without Maven/Gradle, see non-modular sample or modular sample projects.

• JavaFX 11 with Maven, see non-modular sample or modular sample projects.

• JavaFX 11 with Gradle, see non-modular sample or modular sample projects.

If you're trying to grab a range with a dynamically generated string, then you just have to build the string like this:

Range(firstcol & firstrow & ":" & secondcol & secondrow).Select

Here's a recursive solution that just prints the string in reverse order. It should be educational if you're trying to learn recursion. I've also made it "wrong" by actually having 2 print statements; one of them should be commented out. Try to figure out which mentally, or just run experiments. Either way, learn from it.

static void printReverse(String s) {
    if (!s.isEmpty()) {
        System.out.print(s.substring(0, 1));
        printReverse(s.substring(1));
        System.out.print(s.substring(0, 1));
    }
}

Bonus points if you answer these questions:

• What is its stack requirement? Is it prone to stack overflow?
• Is it a tail recursion?

Read your reference more carefully:

Default Values

It's not always necessary to assign a value when a field is declared. Fields that are declared but not initialized will be set to a reasonable default by the compiler. Generally speaking, this default will be zero or null, depending on the data type. Relying on such default values, however, is generally considered bad programming style.

The following chart summarizes the default values for the above data types.

. . .

Local variables are slightly different; the compiler never assigns a default value to an uninitialized local variable. If you cannot initialize your local variable where it is declared, make sure to assign it a value before you attempt to use it. Accessing an uninitialized local variable will result in a compile-time error.

Use WORKSPACE environment variable to change workspace directory.

If doing using Jenkinsfile, use following code :

dir("${env.WORKSPACE}/aQA"){
    sh "pwd"
}

This can be achieved without body-parser dependency as well, listen to request:data and request:end and return the response on end of request, refer below code sample. ref:https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/#request-body

var express = require('express');
var app = express.createServer(express.logger());

app.post('/', function(request, response) {

    // push the data to body
    var body = [];
    request.on('data', (chunk) => {
      body.push(chunk);
    }).on('end', () => {
      // on end of data, perform necessary action
      body = Buffer.concat(body).toString();
      response.write(request.body.user);
      response.end();
    });
});

The following solution works only for single page reports. Refer to comments for more details.

ReportViewer is a server control and thus can not be used within a razor view. However you can add a ASPX view page, view user control or traditional web form that containing a ReportViewer into the application.

You will need to ensure that you have added the relevant handler into your web.config.

If you use a ASPX view page or view user control you will need to set AsyncRendering to false to get the report to display properly.

Update:

Added more sample code. Note there are no meaningful changes required in Global.asax.

Web.Config

Mine ended up as follows:

Controller

The controller actions are very simple.

As a bonus the File() action returns the output of "TestReport.rdlc" as a PDF file.

using System.Web.Mvc;
using Microsoft.Reporting.WebForms;

...

public class PDFController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public FileResult File()
    {
        ReportViewer rv = new Microsoft.Reporting.WebForms.ReportViewer();
        rv.ProcessingMode = ProcessingMode.Local;
        rv.LocalReport.ReportPath = Server.MapPath("~/Reports/TestReport.rdlc");
        rv.LocalReport.Refresh();

        byte[] streamBytes = null;
        string mimeType = "";
        string encoding = "";
        string filenameExtension = "";
        string[] streamids = null;
        Warning[] warnings = null;

        streamBytes = rv.LocalReport.Render("PDF", null, out mimeType, out encoding, out filenameExtension, out streamids, out warnings);

        return File(streamBytes, mimeType, "TestReport.pdf");
    }

    }
}

ASPXView.apsx

The ASPXView is as follows.

bind report to reportviewer in web mvc2

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Select * from a_table where attribute = 'k' COLLATE Latin1_General_CS_AS 

Did the trick.

On CentOS 7, try running following command:

sudo yum install php72u-gd.x86_64

Generally you can just cast the variable to become a short.

You can also get problems like this that can be confusing. This is because the + operator promotes them to an int

Casting the elements won't help:

You need to cast the expression:

Running in a Docker container introduced a whole slew of additional problems for connecting so hopefully this helps someone. I ended up needed to add the following options which I'll explain below:

-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=${DOCKER_HOST_IP}
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.rmi.port=9998

DOCKER_HOST_IP

Unlike using jconsole locally, you have to advertise a different IP than you'll probably see from within the container. You'll need to replace ${DOCKER_HOST_IP} with the externally resolvable IP (DNS Name) of your Docker host.

JMX Remote & RMI Ports

It looks like JMX also requires access to a remote management interface (jstat) that uses a different port to transfer some data when arbitrating the connection. I didn't see anywhere immediately obvious in jconsole to set this value. In the linked article the process was:

• Try and connect from jconsole with logging enabled
• Fail
• Figure out which port jconsole attempted to use
• Use iptables/firewall rules as necessary to allow that port to connect

While that works, it's certainly not an automatable solution. I opted for an upgrade from jconsole to VisualVM since it let's you to explicitly specify the port on which jstatd is running. In VisualVM, add a New Remote Host and update it with values that correlate to the ones specified above:

Then right-click the new Remote Host Connection and Add JMX Connection...

Don't forget to check the checkbox for Do not require SSL connection. Hopefully, that should allow you to connect.

Dictionaries are for look ups. It makes sense to ask if an entry exists or not. Lists are usually iterated. It isn't common to ask if L[10] exists but rather if the length of L is 11.

You could put your text in a select statement such as...

SELECT 'Querying Table1' FROM dual;

Use jquery attr method. It works in all browsers.

var hiddenInput = document.createElement("input");
$(hiddenInput).attr({
    'id':'uniqueIdentifier',
    'type': 'hidden',
    'value': ID,
    'class': 'ListItem'
});

Or you could use folowing code:

var e = $('<input id = "uniqueIdentifier" type="hidden" value="' + ID + '" class="ListItem" />');

Based on kynan's answer, here are the same aliases, modified so they can handle spaces and initial dashes in filenames:

accept-ours = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --ours -- \"$@\"; git add -u -- \"$@\"; }; f"
accept-theirs = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --theirs -- \"$@\"; git add -u -- \"$@\"; }; f"

When you use 'getResource' on a Class, a relative path is resolved based on the package the Class is in. When you use 'getResource' on a ClassLoader, a relative path is resolved based on the root folder.

If you use an absolute path, both 'getResource' methods will start at the root folder.

2 things FYI -

1. For now, they've added a few toggle classes. See what's available in the latest stable release - print toggles in responsive-utilities.less
2. New and improved solution coming in Bootstrap 3.0 - they're adding a separate print.less file. See separate print.less

Try this SELECT DISTINCT 10 * ...

You can use this Eclipse Plugin: http://marketplace.eclipse.org/node/491839#.UIlr8ZDwCUm This is a multi-line string editor popup. Place your caret in a string literal press ctrl-shift-alt-m and paste your text.

They can also provide a kind of naming collision protection for plugin data. For example, the new Change Data Capture feature in SQL Server 2008 puts the tables it uses in a separate cdc schema. This way, they don't have to worry about a naming conflict between a CDC table and a real table used in the database, and for that matter can deliberately shadow the names of the real tables.

Try to Use JSON.stringify

The PRIMARY KEY constraint uniquely identifies each record in a database table. Primary keys must contain UNIQUE values and column cannot contain NULL Values.

  -- DROP current primary key 
  ALTER TABLE tblPersons DROP CONSTRAINT <constraint_name>
  Example:
  ALTER TABLE tblPersons 
  DROP CONSTRAINT P_Id;


  -- ALTER TABLE tblpersion
  ALTER TABLE tblpersion add primary key (P_Id,LastName)

What I did to add to get the files within a symlink into Git (I didn't use a symlink but):

sudo mount --bind SOURCEDIRECTORY TARGETDIRECTORY

Do this command in the Git-managed directory. TARGETDIRECTORY has to be created before the SOURCEDIRECTORY is mounted into it.

It works fine on Linux, but not on OS X! That trick helped me with Subversion too. I use it to include files from an Dropbox account, where a webdesigner does his/her stuff.

if (pictureBox1.Image != null)
{
    pictureBox1.Image.Dispose();
    pictureBox1.Image = null;
}

If you got only one column in the range to clean, just add "(1)" to the end. It indicates in wich column of the range Excel will remove the duplicates. Something like:

 Sub norepeat()

    Range("C8:C16").RemoveDuplicates (1)

End Sub

Edit : See jme's answer for the best way with Python3.

Using pathlib, you have the following solution :

Let's say we want to check if son is a descendant of parent, and both are Path objects. We can get a list of the parts in the path with list(parent.parts). Then, we just check that the begining of the son is equal to the list of segments of the parent.

>>> lparent = list(parent.parts)
>>> lson = list(son.parts)
>>> if lson[:len(lparent)] == lparent:
>>> ... #parent is a parent of son :)

If you want to get the remaining part, you can just do

>>> ''.join(lson[len(lparent):])

It's a string, but you can of course use it as a constructor of an other Path object.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

Address already in use: JVM_Bind

means that some other application is already listening on the port your current application is trying to bind.

what you need to do is, either change the port for your current application or better; just find out the already running application and kill it.

on Linux you can find the application pid by using,

netstat -tulpn

If you change your function definition to use a variable instead:

var get_page = func(url string) string {
    ...
}

You can override it in your tests:

func TestDownloader(t *testing.T) {
    get_page = func(url string) string {
        if url != "expected" {
            t.Fatal("good message")
        }
        return "something"
    }
    downloader()
}

Careful though, your other tests might fail if they test the functionality of the function you override!

The Go authors use this pattern in the Go standard library to insert test hooks into code to make things easier to test:

• https://golang.org/src/net/hook.go
• https://golang.org/src/net/dial.go#L248
• https://golang.org/src/net/dial_test.go#L701

(?<!1\.2\.3\.4).*Has exploded

You need to run this with -P to have negative lookbehind (Perl regular expression), so the command is:

grep -P '(?<!1\.2\.3\.4).*Has exploded' test.log

Try this. It uses negative lookbehind to ignore the line if it is preceeded by 1.2.3.4. Hope that helps!

Basically if you want to set size and make it change then set it to state on layout like this:

import React, { Component } from 'react';
import { AppRegistry, StyleSheet, View } from 'react-native';

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'yellow',
  },
  View1: {
    flex: 2,
    margin: 10,
    backgroundColor: 'red',
    elevation: 1,
  },
  View2: {
    position: 'absolute',
    backgroundColor: 'orange',
    zIndex: 3,
    elevation: 3,
  },
  View3: {
    flex: 3,
    backgroundColor: 'green',
    elevation: 2,
  },
  Text: {
    fontSize: 25,
    margin: 20,
    color: 'white',
  },
});

class Example extends Component {

  constructor(props) {
    super(props);

    this.state = {
      view2LayoutProps: {
        left: 0,
        top: 0,
        width: 50,
        height: 50,
      }
    };
  }

  onLayout(event) {
    const {x, y, height, width} = event.nativeEvent.layout;
    const newHeight = this.state.view2LayoutProps.height + 1;
    const newLayout = {
        height: newHeight ,
        width: width,
        left: x,
        top: y,
      };

    this.setState({ view2LayoutProps: newLayout });
  }

  render() {
    return (
      <View style={styles.container}>
        <View style={styles.View1}>
          <Text>{this.state.view2LayoutProps.height}</Text>
        </View>
        <View onLayout={(event) => this.onLayout(event)} 
              style={[styles.View2, this.state.view2LayoutProps]} />
        <View style={styles.View3} />
      </View>
    );
  }

}


AppRegistry.registerComponent(Example);

You can create many more variation of how it should be modified, by using this in another component which has Another view as wrapper and create an onResponderRelease callback, which could pass the touch event location into the state, which could be then passed to child component as property, which could override onLayout updated state, by placing {[styles.View2, this.state.view2LayoutProps, this.props.touchEventTopLeft]} and so on.

Appearently Browsers still have troubles (although Chrome and Firefox Nightly do fine). I have a hacky approach for the people that really have to use a number field (maybe because of the little arrows that text fields dont have).

My Solution

I added a keyup event Handler to the form input and tracked the state and set the value once it comes valid again.

This will solve the problem =) But I wanted the timeFormat yyyy-mm

Only tried in FF4 though

System.Diagnostics.Process.Start("explorer.exe",@"c:\teste");

Just change the path or declare it in a string

Step1. $ cd [your working path of code]

Step2. $ svn commit [your server path ] -m 'Add commit message'

For help use $ svn help commit

In Spring MVC you get the HtppServletResponce object by default .

   @RequestMapping("/myPath.htm")
    public ModelAndView add(HttpServletRequest request,
         HttpServletResponse response) throws Exception{
            //Do service call passing the response
    return new ModelAndView("CustomerAddView");
    }

//Service code
Cookie myCookie =
  new Cookie("name", "val");
  response.addCookie(myCookie);

People already suggested methods that will try to determine if the program is being compiled in 32-bit or 64-bit.

And I want to add that you can use the c++11 feature static_assert to make sure that the architecture is what you think it is ("to relax").

So in the place where you define the macros:

#if ...
# define IS32BIT
  static_assert(sizeof(void *) == 4, "Error: The Arch is not what I think it is")
#elif ...
# define IS64BIT
  static_assert(sizeof(void *) == 8, "Error: The Arch is not what I think it is")
#else
# error "Cannot determine the Arch"
#endif

You can't access a MySQL DB from Android natively. EDIT: Actually you may be able to use JDBC, but it is not recommended (or may not work?) ... see Android JDBC not working: ClassNotFoundException on driver

See

http://www.helloandroid.com/tutorials/connecting-mysql-database

http://www.basic4ppc.com/forum/basic4android-getting-started-tutorials/8339-connect-android-mysql-database-tutorial.html

Android cannot connect directly to the database server. Therefore we need to create a simple web service that will pass the requests to the database and will return the response.

http://codeoncloud.blogspot.com/2012/03/android-mysql-client.html

For most [good] users this might be fine. But imagine you get a hacker that gets a hold of your program. I've decompiled my own applications and its scary what I've seen. What if they get your username / password to your database and wreak havoc? Bad.

Dim P As String = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().CodeBase)
P = New Uri(P).LocalPath

I don't think it can. When a service is "stopped", it gets totally unloaded.

Well, OK, there's always a way I suppose. For instance, you could create a detached process to stop the service, then restart it, then exit.

An incredibly powerful alternative to other answers here:

ng-class="[  { key: resulting-class-expression }[ key-matching-expression ], ..  ]"

Some examples:

1. Simply adds 'class1 class2 class3' to the div:

<div ng-class="[{true: 'class1'}[true], {true: 'class2 class3'}[true]]"></div>

2. Adds 'odd' or 'even' classes to div, depending on the $index:

<div ng-class="[{0:'even', 1:'odd'}[ $index % 2]]"></div>

3. Dynamically creates a class for each div based on $index

<div ng-class="[{true:'index'+$index}[true]]"></div>

If $index=5 this will result in:

<div class="index5"></div>

Here's a code sample you can run:

var app = angular.module('app', []); _x000D_
app.controller('MyCtrl', function($scope){_x000D_
  $scope.items = 'abcdefg'.split('');_x000D_
}); 

.odd  { background-color: #eee; }_x000D_
.even { background-color: #fff; }_x000D_
.index5 {background-color: #0095ff; color: white; font-weight: bold; }_x000D_
* { font-family: "Courier New", Courier, monospace; }

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>_x000D_
_x000D_
<div ng-app="app" ng-controller="MyCtrl">_x000D_
  <div ng-repeat="item in items"_x000D_
    ng-class="[{true:'index'+$index}[true], {0:'even', 1:'odd'}[ $index % 2 ]]">_x000D_
    index {{$index}} = "{{item}}" ng-class="{{[{true:'index'+$index}[true], {0:'even', 1:'odd'}[ $index % 2 ]].join(' ')}}"_x000D_
  </div>_x000D_
</div>

"Is it possible to run this service always as when the application pause and anything else?"

Yes.

1. In the service onStartCommand method return START_STICKY.

   public int onStartCommand(Intent intent, int flags, int startId) {
           return START_STICKY;
   }
   

2. Start the service in the background using startService(MyService) so that it always stays active regardless of the number of bound clients.

   Intent intent = new Intent(this, PowerMeterService.class);
   startService(intent);
   

3. Create the binder.

   public class MyBinder extends Binder {
           public MyService getService() {
                   return MyService.this;
           }
   }
   

4. Define a service connection.

   private ServiceConnection m_serviceConnection = new ServiceConnection() {
           public void onServiceConnected(ComponentName className, IBinder service) {
                   m_service = ((MyService.MyBinder)service).getService();
           }
   
           public void onServiceDisconnected(ComponentName className) {
                   m_service = null;
           }
   };
   

5. Bind to the service using bindService.

           Intent intent = new Intent(this, MyService.class);
           bindService(intent, m_serviceConnection, BIND_AUTO_CREATE);
   

6. For your service you may want a notification to launch the appropriate activity once it has been closed.

   private void addNotification() {
           // create the notification
           Notification.Builder m_notificationBuilder = new Notification.Builder(this)
                   .setContentTitle(getText(R.string.service_name))
                   .setContentText(getResources().getText(R.string.service_status_monitor))
                   .setSmallIcon(R.drawable.notification_small_icon);
   
           // create the pending intent and add to the notification
           Intent intent = new Intent(this, MyService.class);
           PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
           m_notificationBuilder.setContentIntent(pendingIntent);
   
           // send the notification
           m_notificationManager.notify(NOTIFICATION_ID, m_notificationBuilder.build());
   }
   

7. You need to modify the manifest to launch the activity in single top mode.

             android:launchMode="singleTop"
   

8. Note that if the system needs the resources and your service is not very active it may be killed. If this is unacceptable bring the service to the foreground using startForeground.

           startForeground(NOTIFICATION_ID, m_notificationBuilder.build());
   

Taking everything this is how it was solved for me:

- (void)viewDidLoad {
    NSURL *url = [NSURL URLWithString: @"http://www.amazon.com"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setValue:@"Foobar/1.0" forHTTPHeaderField:@"User-Agent"];
    [webView loadRequest:request];
}

Thanks Everyone.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Just use GetDate() not Select GetDate()

DECLARE @LastChangeDate as date 
SET @LastChangeDate = GETDATE() 

but if it's SQL Server, you can also initialize in same step as declaration...

DECLARE @LastChangeDate date = getDate()

The best solution, to me anyway, is buried in the comments of @ephemient's answer. I am just pulling it up here so that it doesn't go unnoticed. The credit for this should go to @FRoZeN (and @ephemient).

git diff --shortstat `git hash-object -t tree /dev/null`

returns the total of files and lines in the working directory of a repo, without any additional noise. As a bonus, only the source code is counted - binary files are excluded from the tally.

The command above works on Linux and OS X. The cross-platform version of it is

git diff --shortstat 4b825dc642cb6eb9a060e54bf8d69288fbee4904

That works on Windows, too.

For the record, the options for excluding blank lines,

• -w/--ignore-all-space,
• -b/--ignore-space-change,
• --ignore-blank-lines,
• --ignore-space-at-eol

don't have any effect when used with --shortstat. Blank lines are counted.

You have to import the following two libraries:

import java.util.*
import kotlin.concurrent.schedule

and after that use it in this way:

Timer().schedule(10000){
    //do something
}

Complete code to disable SSL hostname verifier,

RestTemplate restTemplate = new RestTemplate();
//to disable ssl hostname verifier
restTemplate.setRequestFactory(new SimpleClientHttpRequestFactory() {
   @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        if (connection instanceof HttpsURLConnection) {
            ((HttpsURLConnection) connection).setHostnameVerifier(new NoopHostnameVerifier());
        }
        super.prepareConnection(connection, httpMethod);
    }
});

Default assignments apply to class members, but not to local variables. As Eric Lippert explained it in this answer, Microsoft could have initialized locals by default, but they choose not to do it because using an unassigned local is almost certainly a bug.

From Ruby API:

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

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

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

require_relative "data/customer_data_1" 

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

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

path must respond to to_str.

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

Wordpress uses MD5 Password hashing. Creates a hash of a plain text password. Unless the global $wp_hasher is set, the default implementation uses PasswordHash, which adds salt to the password and hashes it with 8 passes of MD5. MD5 is used by default because it's supported on all platforms. You can configure PasswordHash to use Blowfish or extended DES (if available) instead of MD5 with the $portable_hashes constructor argument or property.

Why does nobody here consider using this simple code?

TCHAR szDir[MAX_PATH] = { 0 };

GetModuleFileName(NULL, szDir, MAX_PATH);
szDir[std::string(szDir).find_last_of("\\/")] = 0;

or even simpler

TCHAR szDir[MAX_PATH] = { 0 };
TCHAR* szEnd = nullptr;
GetModuleFileName(NULL, szDir, MAX_PATH);
szEnd = _tcsrchr(szDir, '\\');
*szEnd = 0;

Updated: Aug 27 2014 - [updateOrCreate Built into core...]

Just in case people are still coming across this... I found out a few weeks after writing this, that this is in fact part of Laravel's Eloquent's core...

Digging into Eloquent’s equivalent method(s). You can see here:

https://github.com/laravel/framework/blob/4.2/src/Illuminate/Database/Eloquent/Model.php#L553

on :570 and :553

    /**
     * Create or update a record matching the attributes, and fill it with values.
     *
     * @param  array  $attributes
     * @param  array  $values
     * @return static
     */
    public static function updateOrCreate(array $attributes, array $values = array())
    {
        $instance = static::firstOrNew($attributes);

        $instance->fill($values)->save();

        return $instance;
    }

Old Answer Below

I am wondering if there is any built in L4 functionality for doing this in some way such as:

$row = DB::table('table')->where('id', '=', $id)->first();
// Fancy field => data assignments here
$row->save();

I did create this method a few weeks back...

// Within a Model extends Eloquent
public static function createOrUpdate($formatted_array) {
    $row = Model::find($formatted_array['id']);
    if ($row === null) {
        Model::create($formatted_array);
        Session::flash('footer_message', "CREATED");
    } else {
        $row->update($formatted_array);
        Session::flash('footer_message', "EXISITING");
    }
    $affected_row = Model::find($formatted_array['id']);
    return $affected_row;
}

I Hope that helps. I would love to see an alternative to this if anyone has one to share. @erikthedev_

I'd probably do something like that :

[int]::Parse("35")

But I'm not really a Powershell guy. It uses the static Parse method from System.Int32. It should throw an exception if the string can't be parsed.

You will have to use cookie to store the value across page refresh. You can use any one of the many javascript based cookie libraries to simplify the cookie access, like this one

If you want to support only html5 then you can think of Storage api like localStorage/sessionStorage

Ex: using localStorage and cookies library

var mode = getStoredValue('myPageMode');

function buttonClick(mode) {
    mode = mode;
    storeValue('myPageMode', mode);
}

function storeValue(key, value) {
    if (localStorage) {
        localStorage.setItem(key, value);
    } else {
        $.cookies.set(key, value);
    }
}

function getStoredValue(key) {
    if (localStorage) {
        return localStorage.getItem(key);
    } else {
        return $.cookies.get(key);
    }
}

The angular documentation for select* does not answer this question explicitly, but it is there. If you look at the script.js, you will see this:

function MyCntrl($scope) {
  $scope.colors = [
    {name:'black', shade:'dark'},
    {name:'white', shade:'light'},
    {name:'red', shade:'dark'},
    {name:'blue', shade:'dark'},
    {name:'yellow', shade:'light'}
  ];
  $scope.color = $scope.colors[2]; // Default the color to red
}

This is the html:

<select ng-model="color" ng-options="c.name for c in colors"></select>

This seems to be a more obvious way of defaulting a selected value on an <select> with ng-options. Also it will work if you have different label/values.

* This is from Angular 1.2.7

I'm not sure if you meant to include scripting languages, but I've seen TCL (which is also annoying), but... the mIRC scripting language annoys me to no end.

Because of some oversight in the parsing, it's whitespace significant when it's not supposed to be. Conditional statements will sometimes be executed when they're supposed to be skipped because of this. Opening a block statement cannot be done on a separate line, etc.

Other than that it's just full of messy, inconsistent syntax that was probably designed that way to make very basic stuff easy, but at the same time makes anything a little more complex barely readable.

I lost most of my mIRC scripts, or I could have probably found some good examples of what a horrible mess it forces you to create :(

No alternative method is provided in the method's description because the preferred approach (as of API level 11) is to instantiate PreferenceFragment objects to load your preferences from a resource file. See the sample code here: PreferenceActivity

Yes, there's str_to_date

mysql> select str_to_date("03/02/2009","%d/%m/%Y");

To convert Blob to String in Java:

byte[] bytes = baos.toByteArray();//Convert into Byte array
String blobString = new String(bytes);//Convert Byte Array into String

you can fix problem by:

var canvas = $('#canvas'); 
var b64Text = canvas.toDataURL();
b64Text = b64Text.replace('data:image/png;base64,','');
var base64Data = b64Text;

Either of these 2:

NSString *subString = [dateString subStringWithRange:NSMakeRange(0,2)];
NSString *subString = [[dateString componentsSeparatedByString:@"/"] objectAtIndex:0];

Though keep in mind that sometimes a date string is not formatted properly and a day ( or a month for that matter ) is shown as 8, rather than 08 so the first one might be the worst of the 2 solutions.

The latter should be put into a separate array so you can actually check for the length of the thing returned, so you do not get any exceptions thrown in the case of a corrupt or invalid date string from whatever source you have.

This workaround worked for me...

<td style="white-space: normal; width:300px;">

Answer: Only if you plan to make it a command-line executable script.

Here is the procedure:

Start off by verifying the proper shebang string to use:

which python

Take the output from that and add it (with the shebang #!) in the first line.

On my system it responds like so:

$which python
/usr/bin/python

So your shebang will look like:

#!/usr/bin/python

After saving, it will still run as before since python will see that first line as a comment.

python filename.py

To make it a command, copy it to drop the .py extension.

cp filename.py filename

Tell the file system that this will be executable:

chmod +x filename

To test it, use:

./filename

Best practice is to move it somewhere in your $PATH so all you need to type is the filename itself.

sudo cp filename /usr/sbin

That way it will work everywhere (without the ./ before the filename)

Here is a better solution extend Navigation controller and put in storyboard

class NVC: UINavigationController {

    override var preferredStatusBarStyle: UIStatusBarStyle {
              return .lightContent
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    self.navigationBar.isHidden = true
    self.navigationController?.navigationBar.isTranslucent = false
      
     self.navigationBar.barTintColor = UIColor.white
     setStatusBarColor(view : self.view)
    }

                 let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
              statusBar?.backgroundColor = UIColor.black

status bar color will be black and text will be white

Just separate them by comma, like $email_to = "[email protected], [email protected], John Doe <[email protected]>".

You want to read raw lines to avoid problems with backslashes in the input (use -r):

while read -r line; do
   printf "<%s>\n" "$line"
done < file.txt

This will keep whitespace within the line, but removes leading and trailing whitespace. To keep those as well, set the IFS empty, as in

while IFS= read -r line; do
   printf "%s\n" "$line"
done < file.txt

This now is an equivalent of cat < file.txt as long as file.txt ends with a newline.

Note that you must double quote "$line" in order to keep word splitting from splitting the line into separate words--thus losing multiple whitespace sequences.

Why invent wheels yourself while there is a car ready for you? I just find this tools super easy and intuitive to use: Advanced Installer. This one minute video should be enough to impress you. Here is the illustrative user guide.

Use serialize and deserialize methods in SerializationUtils from commons-lang.

Since the desired page will be called from a different domain you need to return jsonp instead of a json.

$.get("http://theSource", {callback : "?" }, "jsonp",  function(data) {
    $('#summary').text(data.result);
});

A '$' in a variable means nothing special to the interpreter, much like an underscore.

From what I've seen, many people using jQuery (which is what your example code looks like to me) tend to prefix variables that contain a jQuery object with a $ so that they are easily identified and not mixed up with, say, integers.

The dollar sign function $() in jQuery is a library function that is frequently used, so a short name is desirable.

Per the MSDN documentation for sys.database_permissions, this query lists all permissions explicitly granted or denied to principals in the database you're connected to:

SELECT DISTINCT pr.principal_id, pr.name, pr.type_desc, 
    pr.authentication_type_desc, pe.state_desc, pe.permission_name
FROM sys.database_principals AS pr
JOIN sys.database_permissions AS pe
    ON pe.grantee_principal_id = pr.principal_id;

Per Managing Databases and Logins in Azure SQL Database, the loginmanager and dbmanager roles are the two server-level security roles available in Azure SQL Database. The loginmanager role has permission to create logins, and the dbmanager role has permission to create databases. You can view which users belong to these roles by using the query you have above against the master database. You can also determine the role memberships of users on each of your user databases by using the same query (minus the filter predicate) while connected to them.

Use case match for early return purpose. It will force you to declare all return branches explicitly, preventing the careless mistake of forgetting to write return somewhere.

Content types are included in HTTP responses because the same, byte for byte sequence of values in the content could be interpreted in more than one way.(*)

Remember that http can transport more than just HTML (js, css and images are obvious examples), and in some cases, the receiver will not know what type of object it's going to receive.

(*) the obvious one here is XHTML - which is XML. If it's served with a content type of application/xml, the receiver ought to just treat it as XML. If it's served up as application/xhtml+xml, then it ought to be treated as XHTML.

MySQL create function syntax:

DELIMITER //

CREATE FUNCTION GETFULLNAME(fname CHAR(250),lname CHAR(250))
    RETURNS CHAR(250)
    BEGIN
        DECLARE fullname CHAR(250);
        SET fullname=CONCAT(fname,' ',lname);
        RETURN fullname;
    END //

DELIMITER ;

Use This Function In Your Query

SELECT a.*,GETFULLNAME(a.fname,a.lname) FROM namedbtbl as a


SELECT GETFULLNAME("Biswarup","Adhikari") as myname;

You cannot execute php functions from JavaScript.

PHP runs on the server before the browser sees it. PHP outputs HTML and JavaScript.

When the browser reads the html and javascript it executes it.

Use:

var ismatch2 = Wildcard.Match("xmlfsdfsd", "xml*");

The JOIN syntax keeps conditions near the table they apply to. This is especially useful when you join a large amount of tables.

By the way, you can do an outer join with the first syntax too:

WHERE a.x = b.x(+)

Or

WHERE a.x *= b.x

Or

WHERE a.x = b.x or a.x not in (select x from b)

@IBInspectable is working for me on iOS 9 , Swift 2.0

extension UIView {

@IBInspectable var borderWidth: CGFloat {
get {
        return layer.borderWidth
    }
    set(newValue) {
        layer.borderWidth = newValue
    }
}

@IBInspectable var cornerRadius: CGFloat {
    get {
        return layer.cornerRadius
    }
    set(newValue) {
        layer.cornerRadius = newValue
    }
}

@IBInspectable var borderColor: UIColor? {
    get {
        if let color = layer.borderColor {
            return UIColor(CGColor: color)
        }
        return nil
    }
    set(newValue) {
        layer.borderColor = newValue?.CGColor
    }
}

If you want to use the es6 template literals, you need braces around the tick marks as well:

<img className="image" src={`images/${this.props.image}`} />

Check the error_reporting, display_errors and display_startup_errors settings in your php.ini file. They should be set to E_ALL and "On" respectively (though you should not use display_errors on a production server, so disable this and use log_errors instead if/when you deploy it). You can also change these settings (except display_startup_errors) at the very beginning of your script to set them at runtime (though you may not catch all errors this way):

error_reporting(E_ALL);
ini_set('display_errors', 'On');

After that, restart server.

If you have configured navigation property 1-n I would recommend you to use:

var query = db.Categories                                  // source
   .SelectMany(c=>c.CategoryMaps,                          // join
      (c, cm) => new { Category = c, CategoryMaps = cm })  // project result
   .Select(x => x.Category);                               // select result

Much more clearer to me and looks better with multiple nested joins.

The argument to split is a regular expression. The period is a regular expression metacharacter that matches anything, thus every character in line is considered to be a split character, and is thrown away, and all of the empty strings between them are thrown away (because they're empty strings). The result is that you have nothing left.

If you escape the period (by adding an escaped backslash before it), then you can match literal periods. (line.split("\\."))

tl;dr

java.time.temporal.ChronoUnit.DAYS.between( 
    earlier.toLocalDate(), 
    later.toLocalDate() 
)

…or…

java.time.temporal.ChronoUnit.HOURS.between( 
    earlier.truncatedTo( ChronoUnit.HOURS )  , 
    later.truncatedTo( ChronoUnit.HOURS ) 
)

java.time

FYI, the Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

The equivalent of Joda-Time DateTime is ZonedDateTime.

ZoneId z = ZoneId.of( "Pacific/Auckland" ) ;
ZonedDateTime now = ZonedDateTime.now( z ) ;

Apparently you want to count the days by dates, meaning you want to ignore the time of day. For example, starting a minute before midnight and ending a minute after midnight should result in a single day. For this behavior, extract a LocalDate from your ZonedDateTime. The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate localDateStart = zdtStart.toLocalDate() ;
LocalDate localDateStop = zdtStop.toLocalDate() ;

Use the ChronoUnit enum to calculate elapsed days or other units.

long days = ChronoUnit.DAYS.between( localDateStart , localDateStop ) ;

Truncate

As for you asking about a more general way to do this counting where you are interested the delta of hours as hour-of-the-clock rather than complete hours as spans-of-time of sixty minutes, use the truncatedTo method.

Here is your example of 14:45 to 15:12 on same day.

ZoneId z = ZoneId.of( "America/Montreal" ); 
ZonedDateTime start = ZonedDateTime.of( 2017 , 1 , 17 , 14 , 45 , 0 , 0 , z );
ZonedDateTime stop = ZonedDateTime.of( 2017 , 1 , 17 , 15 , 12 , 0 , 0 , z );

long hours = ChronoUnit.HOURS.between( start.truncatedTo( ChronoUnit.HOURS ) , stop.truncatedTo( ChronoUnit.HOURS ) );

1

This does not work for days. Use toLocalDate() in this case.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

open command prompt and type

cd\ (enter)

then type

start chrome "www.google.com"(any website you require)

You need to specify workseet. Change line

If Worksheet.Cells(i, 1).Value = "X" Then

to

If Worksheets("Sheet2").Cells(i, 1).Value = "X" Then

UPD:

Try to use following code (but it's not the best approach. As @SiddharthRout suggested, consider about using Autofilter):

Sub LastRowInOneColumn()
   Dim LastRow As Long
   Dim i As Long, j As Long

   'Find the last used row in a Column: column A in this example
   With Worksheets("Sheet2")
      LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
   End With

   MsgBox (LastRow)
   'first row number where you need to paste values in Sheet1'
   With Worksheets("Sheet1")
      j = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
   End With 

   For i = 1 To LastRow
       With Worksheets("Sheet2")
           If .Cells(i, 1).Value = "X" Then
               .Rows(i).Copy Destination:=Worksheets("Sheet1").Range("A" & j)
               j = j + 1
           End If

   Next i

PSR-5: PHPDoc proposes a form of Generics-style notation.

Syntax

Type[]
Type<Type>
Type<Type[, Type]...>
Type<Type[|Type]...>

Values in a Collection MAY even be another array and even another Collection.

Type<Type<Type>>
Type<Type<Type[, Type]...>>
Type<Type<Type[|Type]...>>

Examples

<?php

$x = [new Name()];
/* @var $x Name[] */

$y = new Collection([new Name()]);
/* @var $y Collection<Name> */

$a = new Collection(); 
$a[] = new Model_User(); 
$a->resetChanges(); 
$a[0]->name = "George"; 
$a->echoChanges();
/* @var $a Collection<Model_User> */

Note: If you are expecting an IDE to do code assist then it's another question about if the IDE supports PHPDoc Generic-style collections notation.

From my answer to this question.

It seems to be (as of 2018.03) in code-insider. A directive has been introduced called python.venvFolders:

  "python.venvFolders": [
    "envs",
    ".pyenv",
    ".direnv"
  ],

All you need is to add your virtualenv folder name.

As per limitations in Java, unsigned byte is almost impossible in the current data-type format. You can go for some other libraries of another language for what you are implementing and then you can call them using JNI.

And there's stty, from coreutils

$ stty size
60 120 # <= sample output

It will print the number of rows and columns, or height and width, respectively.

Then you can use either cut or awk to extract the part you want.

That's stty size | cut -d" " -f1 for the height/lines and stty size | cut -d" " -f2 for the width/columns

// copy /tmp/abc.txt to /tmp/abc.txt (target path)

// username and password of 10.1.1.2 is "username" and "password"

sshpass -p "password" scp /tmp/abc.txt [email protected]:/tmp/abc.txt

// install sshpass (ubuntu)

sudo apt-get install sshpass

You got more preparing [for the exam] to do ;-)

The Stack Pointer is a register which holds the address of the next available spot on the stack.

The stack is a area in memory which is reserved to store a stack, that is a LIFO (Last In First Out) type of container, where we store the local variables and return address, allowing a simple management of the nesting of function calls in a typical program.

See this Wikipedia article for a basic explanation of the stack management.

There are a few alternate ways to figure out the currently used python in Linux is:

1. which python command.
2. command -v python command
3. type python command

Similarly On Windows with Cygwin will also result the same.

kuvivek@HOSTNAME ~
$ which python
/usr/bin/python

kuvivek@HOSTNAME ~
$ whereis python
python: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4        /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gz

kuvivek@HOSTNAME ~
$ which python3
/usr/bin/python3

kuvivek@HOSTNAME ~
$ command -v python
/usr/bin/python

kuvivek@HOSTNAME ~
$ type python
python is hashed (/usr/bin/python)

If you are already in the python shell. Try anyone of these. Note: This is an alternate way. Not the best pythonic way.

>>> import os
>>> os.popen('which python').read()
'/usr/bin/python\n'
>>>
>>> os.popen('type python').read()
'python is /usr/bin/python\n'
>>>
>>> os.popen('command -v python').read()
'/usr/bin/python\n'
>>>
>>>

If you are not sure of the actual path of the python command and is available in your system, Use the following command.

pi@osboxes:~ $ which python
/usr/bin/python
pi@osboxes:~ $ readlink -f $(which python)
/usr/bin/python2.7
pi@osboxes:~ $ 
pi@osboxes:~ $ which python3
/usr/bin/python3
pi@osboxes:~ $ 
pi@osboxes:~ $ readlink -f $(which python3)
/usr/bin/python3.7

This is a bug in the Eclipse Android tools.

To fix: Right click on the project, go to Android tools -> Rename application package.

And also check AndroidManifest.xml if it updated correctly. In my case it didn't, and that should solve this problem.

Typically, you'd use the NODE_ENV variable to take special actions when you develop, test and debug your code. For example to produce detailed logging and debug output which you don't want in production. Express itself behaves differently depending on whether NODE_ENV is set to production or not. You can see this if you put these lines in an Express app, and then make a HTTP GET request to /error:

app.get('/error', function(req, res) {
  if ('production' !== app.get('env')) {
    console.log("Forcing an error!");
  }
  throw new Error('TestError');
});

app.use(function (req, res, next) {
  res.status(501).send("Error!")
})

Note that the latter app.use() must be last, after all other method handlers!

If you set NODE_ENV to production before you start your server, and then send a GET /error request to it, you should not see the text Forcing an error! in the console, and the response should not contain a stack trace in the HTML body (which origins from Express). If, instead, you set NODE_ENV to something else before starting your server, the opposite should happen.

In Linux, set the environment variable NODE_ENV like this:

export NODE_ENV='value'

You seem to want to use a CURSOR. Though most of the times it's best to use a set based solution, there are some times where a CURSOR is the best solution. Without knowing more about your real problem, we can't help you more than that:

DECLARE @PractitionerId int

DECLARE MY_CURSOR CURSOR 
  LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR 
SELECT DISTINCT PractitionerId 
FROM Practitioner

OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @PractitionerId
WHILE @@FETCH_STATUS = 0
BEGIN 
    --Do something with Id here
    PRINT @PractitionerId
    FETCH NEXT FROM MY_CURSOR INTO @PractitionerId
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR

I reset inline transform styles like:

element.style.webkitTransform = "";
element.style.MozTransform = "";
element.style.msTransform = "";
element.style.OTransform = "";
element.style.transform = "";

And like this using jQuery:

$(element).css({
    "webkitTransform":"",
    "MozTransform":"",
    "msTransform":"",
    "OTransform":"",
    "transform":""
});

Depending on the hibernate flush mode that you are using (AUTO is the default) save may or may not write your changes to the DB straight away. When you call saveAndFlush you are enforcing the synchronization of your model state with the DB.

If you use flush mode AUTO and you are using your application to first save and then select the data again, you will not see a difference in bahvior between save() and saveAndFlush() because the select triggers a flush first. See the documention.

We found out that all the standard ways of getting the total memory of the current process have some issues.

• Runtime.getRuntime().totalMemory(): returns JVM memory only
• ActivityManager.getMemoryInfo(), Process.getFreeMemory() and anything else based on /proc/meminfo - returns memory info about all the processes combined (e.g. android_util_Process.cpp)
• Debug.getNativeHeapAllocatedSize() - uses mallinfo() which return information about memory allocations performed by malloc() and related functions only (see android_os_Debug.cpp)
• Debug.getMemoryInfo() - does the job but it's too slow. It takes about 200ms on Nexus 6 for a single call. The performance overhead makes this function useless for us as we call it regularly and every call is quite noticeable (see android_os_Debug.cpp)
• ActivityManager.getProcessMemoryInfo(int[]) - calls Debug.getMemoryInfo() internally (see ActivityManagerService.java)

Finally, we ended up using the following code:

const long pageSize = 4 * 1024; //`sysconf(_SC_PAGESIZE)`
string stats = File.ReadAllText("/proc/self/statm");
var statsArr = stats.Split(new [] {' ', '\t', '\n'}, 3);

if( statsArr.Length < 2 )
    throw new Exception("Parsing error of /proc/self/statm: " + stats);

return long.Parse(statsArr[1]) * pageSize;

It returns VmRSS metric. You can find more details about it here: one, two and three.

P.S. I noticed that the theme still has a lack of an actual and simple code snippet of how to estimate the private memory usage of the process if the performance isn't a critical requirement:

Debug.MemoryInfo memInfo = new Debug.MemoryInfo();
Debug.getMemoryInfo(memInfo);
long res = memInfo.getTotalPrivateDirty();

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) 
    res += memInfo.getTotalPrivateClean(); 

return res * 1024L;

You could also try posix_memalign() (on POSIX platforms, of course).

You have to set to element_blank() in theme() elements you need to remove

ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
  theme(axis.title.x=element_blank(),
        axis.text.x=element_blank(),
        axis.ticks.x=element_blank())

Most of the time we login to remote server using ssh. If you start a shell script and you logout then the process is killed. Nohup helps to continue running the script in background even after you log out from shell.

Nohup command name &
eg: nohup sh script.sh &

Nohup catches the HUP signals. Nohup doesn't put the job automatically in the background. We need to tell that explicitly using &

Note:

Function was written to handle seeding of randomized set creation. You should not rely on set splitting that doesn't randomize the sets.

import numpy as np
import pandas as pd

def train_validate_test_split(df, train_percent=.6, validate_percent=.2, seed=None):
    np.random.seed(seed)
    perm = np.random.permutation(df.index)
    m = len(df.index)
    train_end = int(train_percent * m)
    validate_end = int(validate_percent * m) + train_end
    train = df.iloc[perm[:train_end]]
    validate = df.iloc[perm[train_end:validate_end]]
    test = df.iloc[perm[validate_end:]]
    return train, validate, test

Demonstration

np.random.seed([3,1415])
df = pd.DataFrame(np.random.rand(10, 5), columns=list('ABCDE'))
df

train, validate, test = train_validate_test_split(df)

train

validate

To clarify, the above example does work, my code in the example did not work for unrelated reasons.

If myvar is false, null or has never been used before (i.e. $scope.myvar or $rootScope.myvar never called), the div will not show. Once any value has been assigned to it, the div will show, except if the value is specifically false.

The following will cause the div to show:

$scope.myvar = "Hello World";

or

$scope.myvar = true;

The following will hide the div:

$scope.myvar = null;

or

$scope.myvar = false;

I would like to point out that the solutions given above do not "just work" with non-trivial queries. One issue I came across were more complicated types, such as pgsql ARRAYs causing issues. I did find a solution that for me, did just work even with pgsql ARRAYs:

The linked code seems to be based on an older version of SQLAlchemy. You'll get an error saying that the attribute _mapper_zero_or_none doesn't exist. Here's an updated version that will work with a newer version, you simply replace _mapper_zero_or_none with bind. Additionally, this has support for pgsql arrays:

Personally I use a Perl one-liner:

perl -e "sleep 10;"

for a 10-second wait. Chances are you'll already have Perl installed on a development machine as part of your git installation; if not you will have to install it, for example, from ActiveState or Strawberry, but it's one of those things I install anyway.

Alternatively, you can install a sleep command from GnuWin32.

Try adding WorksheetFunction:

If Not IsError(Application.WorksheetFunction.Match(ValueToSearchFor, RangeToSearchIn, 0)) Then
' String is in range

Add this code into the css file:

input {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}

This will help.

There is also another convention, used by many open source projects including Spring.

interface User {
}

class DefaultUser implements User {
}

class AnotherClassOfUser implements User {
}

I personally do not like the "I" prefix for the simple reason that its an optional convention. So if I adopt this does IIOPConnection mean an interface for IOPConnection? What if the class does not have the "I" prefix, do I then know its not an interface..the answer here is no, because conventions are not always followed, and policing them will create more work that the convention itself saves.

In case you have PyQt4 installed, try the following code:

from PyQt4 import QtGui
import sys

MyApp = QtGui.QApplication(sys.argv)
V = MyApp.desktop().screenGeometry()
h = V.height()
w = V.width()
print("The screen resolution (width X height) is the following:")
print(str(w) + "X" + str(h))

For PyQt5, the following will work:

from PyQt5 import QtWidgets
import sys

MyApp = QtWidgets.QApplication(sys.argv)
V = MyApp.desktop().screenGeometry()
h = V.height()
w = V.width()
print("The screen resolution (width X height) is the following:")
print(str(w) + "X" + str(h))

When running the test use the -s option. All print statements in exampletest.py would get printed on the console when test is run.

py.test exampletest.py -s

I happen to be learning prototype from You Don't Know JS: this & Object Prototypes, which is a wonderful book to understand the design underneath and clarify so many misconceptions (that's why I'm trying to avoid using inheritance and things like instanceof).

But I have the same question as people asked here. Several answers are really helpful and enlightening. I'd also love to share my understandings.

What is a prototype?

Objects in JavaScript have an internal property, denoted in the specification as[[Prototype]], which is simply a reference to another object. Almost all objects are given a non-nullvalue for this property, at the time of their creation.

How to get an object's prototype?

via __proto__or Object.getPrototypeOf

var a = { name: "wendi" };
a.__proto__ === Object.prototype // true
Object.getPrototypeOf(a) === Object.prototype // true

function Foo() {};
var b = new Foo();
b.__proto__ === Foo.prototype
b.__proto__.__proto__ === Object.prototype

What is the prototype ?

prototype is an object automatically created as a special property of a function, which is used to establish the delegation (inheritance) chain, aka prototype chain.

When we create a function a, prototype is automatically created as a special property on a and saves the function code on as the constructor on prototype.

function Foo() {};
Foo.prototype // Object {constructor: function}
Foo.prototype.constructor === Foo // true

I'd love to consider this property as the place to store the properties (including methods) of a function object. That's also the reason why utility functions in JS are defined like Array.prototype.forEach() , Function.prototype.bind(), Object.prototype.toString().

Why to emphasize the property of a function?

{}.prototype // undefined;
(function(){}).prototype // Object {constructor: function}

// The example above shows object does not have the prototype property.
// But we have Object.prototype, which implies an interesting fact that
typeof Object === "function"
var obj = new Object();

So, Arary, Function, Objectare all functions. I should admit that this refreshes my impression on JS. I know functions are first-class citizen in JS but it seems that it is built on functions.

What's the difference between __proto__ and prototype?

__proto__a reference works on every object to refer to its [[Prototype]]property.

prototype is an object automatically created as a special property of a function, which is used to store the properties (including methods) of a function object.

With these two, we could mentally map out the prototype chain. Like this picture illustrates:

function Foo() {}
var b = new Foo();

b.__proto__ === Foo.prototype // true
Foo.__proto__ === Function.prototype // true
Function.prototype.__proto__ === Object.prototype // true

For Xcode 4.1 you can simply add /Developer/usr/bin to the PATH environment variable. This is easily done:

$ export PATH=$PATH:/Developer/usr/bin

Also be certain to update your ~/.bashrc (or ~/.profile or ~/.bash_login) file.

Definitely use Pyglet for this. It's kind of a large package, but it is pure python with no extension modules. That will definitely be the easiest for deployment. It's also got great format and codec support.

import pyglet

music = pyglet.resource.media('music.mp3')
music.play()

pyglet.app.run()

When you run a jar, your Main class itself becomes args[0] and your filename comes immediately after.

I had the same issue: I could locate my file when provided the absolute path from eclipse (because I was referring to the file as args[0]). Yet when I run the same from jar, it was trying to locate my main class - which is when I got the idea that I should be reading my file from args[1].

In python, this is called "unpacking", and you can find a bit about it in the tutorial. The documentation of it sucks, I agree, especially because of how fantasically useful it is.

The first line of a paragraph is indented by default, thus whether or not you have \indent there won't make a difference. \indent and \noindent can be used to override default behavior. You can see this by replacing your line with the following:

Now we are engaged in a great civil war.\\
\indent this is indented\\
this isn't indented


\noindent override default indentation (not indented)\\

...allow use of an ORDER BY in a view definition.

That's not a good idea. A view should never have an ORDER BY defined.

An ORDER BY has an impact on performance - using it a view means that the ORDER BY will turn up in the explain plan. If you have a query where the view is joined to anything in the immediate query, or referenced in an inline view (CTE/subquery factoring) - the ORDER BY is always run prior to the final ORDER BY (assuming it was defined). There's no benefit to ordering rows that aren't the final result set when the query isn't using TOP (or LIMIT for MySQL/Postgres).

Consider:

CREATE VIEW my_view AS
    SELECT i.item_id,
           i.item_description,
           it.item_type_description
      FROM ITEMS i
      JOIN ITEM_TYPES it ON it.item_type_id = i.item_type_id
  ORDER BY i.item_description

...

  SELECT t.item_id,
         t.item_description,
         t.item_type_description
    FROM my_view t
ORDER BY t.item_type_description

...is the equivalent to using:

  SELECT t.item_id,
         t.item_description,
         t.item_type_description
    FROM (SELECT i.item_id,
                 i.item_description,
                 it.item_type_description
            FROM ITEMS i
            JOIN ITEM_TYPES it ON it.item_type_id = i.item_type_id
        ORDER BY i.item_description) t
ORDER BY t.item_type_description

This is bad because:

1. The example is ordering the list initially by the item description, and then it's reordered based on the item type description. It's wasted resources in the first sort - running as is does not mean it's running: ORDER BY item_type_description, item_description
2. It's not obvious what the view is ordered by due to encapsulation. This does not mean you should create multiple views with different sort orders...

I got the error by having multiple tables on the page and trying to initialize them all at once like this:

$('table').DataTable();

After a lot of trial and error, I initialized them separately and the error went away:

$("#table1-id").DataTable();
$("#table2-id").DataTable();

Great solutions here, just one more option that taking into consideration handling of null values:

Map<String,Object> map = new HashMap<>();

Map<String,String> stringifiedMap = map.entrySet().stream()
             .filter(m -> m.getKey() != null && m.getValue() !=null)
             .collect(Collectors.toMap(Map.Entry::getKey, e -> (String)e.getValue()));

Use this query:

DELETE FROM tableName;

Note: To delete some specific record you can give the condition in where clause in the query also.

OR you can use this query also:

truncate tableName;

Also remember that you should not have any relationship with other table. If there will be any foreign key constraint in the table then those record will not be deleted and will give the error.

string(byteslice) will convert byte slice to string, just know that it's not only simply type conversion, but also memory copy.

use Date.prototype.toLocaleTimeString() as documented here

This is what I use, but it is slow on large text files.

get-content $pathToFile | % { $_ -replace $stringToReplace, $replaceWith } | set-content $pathToFile

If you are going to be replacing strings in large text files and speed is a concern, look into using System.IO.StreamReader and System.IO.StreamWriter.

try
{
   $reader = [System.IO.StreamReader] $pathToFile
   $data = $reader.ReadToEnd()
   $reader.close()
}
finally
{
   if ($reader -ne $null)
   {
       $reader.dispose()
   }
}

$data = $data -replace $stringToReplace, $replaceWith

try
{
   $writer = [System.IO.StreamWriter] $pathToFile
   $writer.write($data)
   $writer.close()
}
finally
{
   if ($writer -ne $null)
   {
       $writer.dispose()
   }
}

(The code above has not been tested.)

There is probably a more elegant way to use StreamReader and StreamWriter for replacing text in a document, but that should give you a good starting point.

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)
    }
}

I had a similar issue and found that pandas.get_dummies() solved the problem. Specifically, it splits out columns of categorical data into sets of boolean columns, one new column for each unique value in each input column. In your case, you would replace train_x = test[cols] with:

train_x = pandas.get_dummies(test[cols])

This transforms the train_x Dataframe into the following form, which RandomForestClassifier can accept:

   C  A_Hello  A_Hola  B_Bueno  B_Hi
0  0        1       0        0     1
1  1        0       1        1     0

Class.forName(nameString).newInstance();

If this is happening in a test class, make sure you haven't forgotten to annotate the class.

For example, in Spring Boot:

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyTests {
    ....

Some time elapses...

Spring Boot continues to evolve. It is no longer required to use @RunWith if you use the correct version of JUnit.

For @SpringBootTest to work stand alone, you need to use @Test from JUnit5 instead of JUnit4.

//import org.junit.Test; // JUnit4
import org.junit.jupiter.api.Test; // JUnit5

@SpringBootTest
public class MyTests {
    ....

If you get this configuration wrong your tests will compile, but @Autowired and @Value fields (for example) will be null. Since Spring Boot operates by magic, you may have few avenues for directly debugging this failure.

There is a whole Section in the docs called 16.3.3.4 Mapping the request body with the @RequestBody annotation. And one called 16.3.3.5 Mapping the response body with the @ResponseBody annotation. I suggest you consult those sections. Also relevant: @RequestBody javadocs, @ResponseBody javadocs

Usage examples would be something like this:

Using a JavaScript-library like JQuery, you would post a JSON-Object like this:

{ "firstName" : "Elmer", "lastName" : "Fudd" }

Your controller method would look like this:

// controller
@ResponseBody @RequestMapping("/description")
public Description getDescription(@RequestBody UserStats stats){
    return new Description(stats.getFirstName() + " " + stats.getLastname() + " hates wacky wabbits");
}

// domain / value objects
public class UserStats{
    private String firstName;
    private String lastName;
    // + getters, setters
}
public class Description{
    private String description;
    // + getters, setters, constructor
}

Now if you have Jackson on your classpath (and have an <mvc:annotation-driven> setup), Spring would convert the incoming JSON to a UserStats object from the post body (because you added the @RequestBody annotation) and it would serialize the returned object to JSON (because you added the @ResponseBody annotation). So the Browser / Client would see this JSON result:

{ "description" : "Elmer Fudd hates wacky wabbits" }

See this previous answer of mine for a complete working example: https://stackoverflow.com/a/5908632/342852

Note: RequestBody / ResponseBody is of course not limited to JSON, both can handle multiple formats, including plain text and XML, but JSON is probably the most used format.

Update

Ever since Spring 4.x, you usually won't use @ResponseBody on method level, but rather @RestController on class level, with the same effect.

Here is a quote from the official Spring MVC documentation:

@RestController is a composed annotation that is itself meta-annotated with @Controller and @ResponseBody to indicate a controller whose every method inherits the type-level @ResponseBody annotation and, therefore, writes directly to the response body versus view resolution and rendering with an HTML template.

In pyspark DOCS it would be subtract

df1.subtract(df2)

Building on the previous answer by @BadPirate, I experimented a bit further and came up with some clarifications/corrections. I found that layoutSubviews: will be called on a view if and only if:

• Its own bounds (not frame) changed.
• The bounds of one of its direct subviews changed.
• A subview is added to the view or removed from the view.

Some relevant details:

• The bounds are considered changed only if the new value is different, including a different origin. Note specifically that is why layoutSubviews: is called whenever a UIScrollView scrolls, as it performs the scrolling by changing its bounds' origin.
• Changing the frame will only change the bounds if the size has changed, as this is the only thing propagated to the bounds property.
• A change in bounds of a view that is not yet in a view hierarchy will result in a call to layoutSubviews: when the view is eventually added to a view hierarchy.
• And just for completeness: these triggers do not directly call layoutSubviews, but rather call setNeedsLayout, which sets/raises a flag. Each iteration of the run loop, for all views in the view hierarchy, this flag is checked. For each view where the flag is found raised, layoutSubviews: is called on it and the flag is reset. Views higher up the hierarchy will be checked/called first.

I uninstalled it on Genymotion. Then run react-native run-android to build the app. And it worked. Do try this first before running sudo ./gradlew clean, it will save you a lot of time.

FINALLY Got this working after 4 hours of installing, uninstalling, updating, blah blah.

The only thing that did it was to use an older version of node v8.9.1 x64

This was a PC windows 10.

Hope this helps someone.

The first thing to do is to determine your definition of "line of code" (LOC). In both your question

It counts a line with just one } as a line and he doesn't want that to count as "its not a line, its a style choice"

and in the answers, e.g.,

You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want

you can tell that people have different opinions as to what constitutes a line of code. In particular, people are often imprecise about whether they really want the number of lines of code or the number of statements. For example, if you have the following really long line filled with statements, what do you want to report, 1 LOC or hundreds of statements?

{ a = 1; b = 2; if (a==c) b++; /* etc. for another 1000 characters */ }

And when somebody asks you what you are calling a LOC, make sure you can answer, even if it is just "my definition of a LOC is Metrics2's definition". In general, for most commonly formatted code (unlike my example), the popular tools will give numbers fairly similar, so Metrics2, SonarQube, etc. should all be fine, as long as you use them consistently. In other words, don't count the LOC of some code using one tool and compare that value to a later version of that code that was measured with a different tool.

I have to make an application which shows the Contact no of the SIM card that is being used in the cell. For that I need to use Telephony Manager class. Can i get details on its usage?

Yes, You have to use Telephony Manager;If at all you not found the contact no. of user; You can get Sim Serial Number of Sim Card and Imei No. of Android Device by using the same Telephony Manager Class...

Add permission:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Import:

import android.telephony.TelephonyManager;

Use the below code:

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

         // get IMEI
         imei = tm.getDeviceId();

         // get SimSerialNumber
         simSerialNumber = tm.getSimSerialNumber();

You have a few options available. You'll want to get comfortable with python's string iterpolation. Which is a term you might have more success searching for in the future when you want to know stuff like this.

Better for queries:

some_dictionary_with_the_data = {
    'name': 'awesome song',
    'artist': 'some band',
    etc...
}
cursor.execute ("""
            INSERT INTO Songs (SongName, SongArtist, SongAlbum, SongGenre, SongLength, SongLocation)
            VALUES
                (%(name)s, %(artist)s, %(album)s, %(genre)s, %(length)s, %(location)s)

        """, some_dictionary_with_the_data)

Considering you probably have all of your data in an object or dictionary already, the second format will suit you better. Also it sucks to have to count "%s" appearances in a string when you have to come back and update this method in a year :)

One very small nit to pick:

The RFC for email addresses allows the first part to include an "@" sign if it is quoted. Example:

"john@work"@myemployer.com

This is quite uncommon, but could happen. Theoretically, you should split on the last "@" symbol, not the first:

SELECT LEN(EmailField) - CHARINDEX('@', REVERSE(EmailField)) + 1

More information:

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

If you are using c# on the desktop, you can use SimpleMapi. That way it will be sent using the default mail client, and the user has the option of reviewing the message before sending, just like mailto:.

To use it you add the Simple-MAPI.NET package (it's 13Kb), and run:

var mapi = new SimpleMapi();
mapi.AddRecipient(null, address, false);
mapi.Attach(path);
//mapi.Logon(ParentForm.Handle);    //not really necessary
mapi.Send(subject, body, true);

If you want to do multiple commands, you could use:

for I in `ls *.sql`
do
    grep "foo" $I >> foo.log
    grep "bar" $I >> bar.log
done

In Windows 7 it is at the path

C:\Users\[username]\.android

• goto this path and remove debug.keystore
• clean and build your project.

The easiest way is to use the replace method on the column. The arguments are a list of the things you want to replace (here ['ABC', 'AB']) and what you want to replace them with (the string 'A' in this case):

>>> df['BrandName'].replace(['ABC', 'AB'], 'A')
0    A
1    B
2    A
3    D
4    A

This creates a new Series of values so you need to assign this new column to the correct column name:

df['BrandName'] = df['BrandName'].replace(['ABC', 'AB'], 'A')

I'm using the following configuration:

#site.yml:
- name: Example play
  hosts: all
  remote_user: ansible
  become: yes
  become_method: sudo
  vars:
    ansible_ssh_private_key_file: "/home/ansible/.ssh/id_rsa"

HashMap is an array of Entry objects.

Consider HashMap as just an array of objects.

Have a look at what this Object is:

static class Entry<K,V> implements Map.Entry<K,V> {
        final K key;
        V value;
        Entry<K,V> next;
        final int hash;
… 
}

Each Entry object represents a key-value pair. The field next refers to another Entry object if a bucket has more than one Entry.

Sometimes it might happen that hash codes for 2 different objects are the same. In this case, two objects will be saved in one bucket and will be presented as a linked list. The entry point is the more recently added object. This object refers to another object with the next field and so on. The last entry refers to null.

When you create a HashMap with the default constructor

HashMap hashMap = new HashMap();

The array is created with size 16 and default 0.75 load balance.

Adding a new key-value pair

1. Calculate hashcode for the key
2. Calculate position hash % (arrayLength-1) where element should be placed (bucket number)
3. If you try to add a value with a key which has already been saved in HashMap, then value gets overwritten.
4. Otherwise element is added to the bucket.

If the bucket already has at least one element, a new one gets added and placed in the first position of the bucket. Its next field refers to the old element.

Deletion

1. Calculate hashcode for the given key
2. Calculate bucket number hash % (arrayLength-1)
3. Get a reference to the first Entry object in the bucket and by means of equals method iterate over all entries in the given bucket. Eventually we will find the correct Entry. If a desired element is not found, return null

So I added curl AFTER my docker container was running.

(This was for debugging the container...I did not need a permanent addition)

I ran my image

docker run -d -p 8899:8080 my-image:latest

(the above makes my "app" available on my machine on port 8899) (not important to this question)

Then I listed and created terminal into the running container.

docker ps
docker exec -it my-container-id-here /bin/sh

If the exec command above does not work, check this SOF article:

Error: Cannot Start Container: stat /bin/sh: no such file or directory"

then I ran:

apk

just to prove it existed in the running container, then i ran:

apk add curl

and got the below:

apk add curl

Note, to get "out" of the drilled-in-terminal-window, I had to open a new terminal window and stop the running container:

docker ps

APPEND:

If you don't have "apk" (which depends on which base image you are using), then try to use "another" installer. From other answers here, you can try:

Go Windows -> Perspective -> Reset Perspective definetly this one help you.

TLS (Transport Level Security) is the slightly broader term that has replaced SSL (Secure Sockets Layer) in securing HTTP communications. So what you are being asked to do is enable SSL.

Maybe you could try this? I use this in my programs.

Data= open ('data.txt', 'r')
data = Data.readlines()
for i in range(len(data)):
    data[i] = data[i].strip()+ ' '
data = ''.join(data).strip()

Use finishAffinity(); in task C when starting task A to clear backstack activities.

If you are looking for the solution in Android Studio :

1. Right click on your app
2. Open Module Settings
3. Select Dependencies tab
4. Click on green + symbol which is on the right side
5. Select Library Dependency
6. Choose appcompat-v7 from list

Passing an array of items as a collapsed parameter to the WHERE..IN clause will fail since query will take form of WHERE Age IN ("11, 13, 14, 16").

But you can pass your parameter as an array serialized to XML or JSON:

Using nodes() method:

StringBuilder sb = new StringBuilder();

foreach (ListItem item in ddlAge.Items)
  if (item.Selected)
    sb.Append("<age>" + item.Text + "</age>"); // actually it's xml-ish

sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
    SELECT Tab.col.value('.', 'int') as Age from @Ages.nodes('/age') as Tab(col))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = sb.ToString();

Using OPENXML method:

using System.Xml.Linq;
...
XElement xml = new XElement("Ages");

foreach (ListItem item in ddlAge.Items)
  if (item.Selected)
    xml.Add(new XElement("age", item.Text);

sqlComm.CommandText = @"DECLARE @idoc int;
    EXEC sp_xml_preparedocument @idoc OUTPUT, @Ages;
    SELECT * from TableA WHERE Age IN (
    SELECT Age from OPENXML(@idoc, '/Ages/age') with (Age int 'text()')
    EXEC sp_xml_removedocument @idoc";
sqlComm.Parameters.Add("@Ages", SqlDbType.Xml);
sqlComm.Parameters["@Ages"].Value = xml.ToString();

That's a bit more on the SQL side and you need a proper XML (with root).

Using OPENJSON method (SQL Server 2016+):

using Newtonsoft.Json;
...
List<string> ages = new List<string>();

foreach (ListItem item in ddlAge.Items)
  if (item.Selected)
    ages.Add(item.Text);

sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
    select value from OPENJSON(@Ages))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = JsonConvert.SerializeObject(ages);

Note that for the last method you also need to have Compatibility Level at 130+.
