Firefox 64 adds support for the spec draft CSS Scrollbars Module Level 1, which adds two new properties of scrollbar-width and scrollbar-color which give some control over how scrollbars are displayed.

You can set scrollbar-color to one of the following values (descriptions from MDN):

• auto Default platform rendering for the track portion of the scrollbar, in the absence of any other related scrollbar color properties.
• dark Show a dark scrollbar, which can be either a dark variant of scrollbar provided by the platform, or a custom scrollbar with dark colors.
• light Show a light scrollbar, which can be either a light variant of scrollbar provided by the platform, or a custom scrollbar with light colors.
• <color> <color> Applies the first color to the scrollbar thumb, the second to the scrollbar track.

Note that dark and light values are not currently implemented in Firefox.

macOS notes:

The auto-hiding semi-transparent scrollbars that are the macOS default cannot be colored with this rule (they still choose their own contrasting color based on the background). Only the permanently showing scrollbars (System Preferences > Show Scroll Bars > Always) are colored.

Visual Demo:

.scroll {_x000D_
  width: 20%;_x000D_
  height: 100px;_x000D_
  border: 1px solid grey;_x000D_

</div>

You can set scrollbar-width to one of the following values (descriptions from MDN):

• auto The default scrollbar width for the platform.
• thin A thin scrollbar width variant on platforms that provide that option, or a thinner scrollbar than the default platform scrollbar width.
• none No scrollbar shown, however the element will still be scrollable.

You can also set a specific length value, according to the spec. Both thin and a specific length may not do anything on all platforms, and what exactly it does is platform-specific. In particular, Firefox doesn't appear to be currently support a specific length value (this comment on their bug tracker seems to confirm this). The thin keywork does appear to be well-supported however, with macOS and Windows support at-least.

It's probably worth noting that the length value option and the entire scrollbar-width property are being considered for removal in a future draft, and if that happens this particular property may be removed from Firefox in a future version.

Visual Demo:

.scroll {_x000D_
  width: 30%;_x000D_
  height: 100px;_x000D_

Here is the simple example which you can use for initial learning:

import java.util.Comparator;
import java.util.PriorityQueue;
import java.util.Queue;
import java.util.Random;

public class PQExample {

    public static void main(String[] args) {
        //PriorityQueue with Comparator
        Queue<Customer> cpq = new PriorityQueue<>(7, idComp);
        addToQueue(cpq);
        pollFromQueue(cpq);
    }

    public static Comparator<Customer> idComp = new Comparator<Customer>(){

        @Override
        public int compare(Customer o1, Customer o2) {
            return (int) (o1.getId() - o2.getId());
        }

    };

    //utility method to add random data to Queue
    private static void addToQueue(Queue<Customer> cq){
        Random rand = new Random();
        for(int i=0;i<7;i++){
            int id = rand.nextInt(100);
            cq.add(new Customer(id, "KV"+id));
        }
    }


    private static void pollFromQueue(Queue<Customer> cq){
        while(true){
            Customer c = cq.poll();
            if(c == null) break;
            System.out.println("Customer Polled : "+c.getId() + " "+ c.getName());
        }
    }

}

JetBrains has a new application called the Toolbox App which quickly and easily installs any JetBrains software you want, assuming you have the license. It also manages your login once to apply across all JetBrains software, a very useful feature.

To use it, download the tar.gz file here, then extract it and run the included executable jetbrains-toolbox. Then sign in, and press install next to IntelliJ IDEA:

If you want to move the executable to /usr/bin/ feel free, however it works fine out of the box wherever you extract it to.

This will also make the appropriate desktop entries upon install.

You can use either of the following:

include "class.twitter.php";

or

require "class.twitter.php";

Using require (or require_once if you want to ensure the class is only loaded once during execution) will cause a fatal error to be raised if the file doesn't exist, whereas include will only raise a warning. See http://php.net/require and http://php.net/include for more details

While probably not as clean looking as the IConvertible approach, you could always use the straightforward checking typeof(T) to return a T:

public static T ReturnType<T>(string stringValue)
{
    if (typeof(T) == typeof(int))
        return (T)(object)1;
    else if (typeof(T) == typeof(FooBar))
        return (T)(object)new FooBar(stringValue);
    else
        return default(T);
}

public class FooBar
{
    public FooBar(string something)
    {}
}

Application.Exit() kills your application but there are some instances that it won't close the application.

End is better than Application.Exit().

I just ran into this same problem, it seems like Yaroslav Bulatov's suggestion doesn't cover SSE4.2 support, adding --copt=-msse4.2 would suffice. In the end, I successfully built with

bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both --copt=-msse4.2 --config=cuda -k //tensorflow/tools/pip_package:build_pip_package

without getting any warning or errors.

Probably the best choice for any system is:

bazel build -c opt --copt=-march=native --copt=-mfpmath=both --config=cuda -k //tensorflow/tools/pip_package:build_pip_package

(Update: the build scripts may be eating -march=native, possibly because it contains an =.)

-mfpmath=both only works with gcc, not clang. -mfpmath=sse is probably just as good, if not better, and is the default for x86-64. 32-bit builds default to -mfpmath=387, so changing that will help for 32-bit. (But if you want high-performance for number crunching, you should build 64-bit binaries.)

I'm not sure what TensorFlow's default for -O2 or -O3 is. gcc -O3 enables full optimization including auto-vectorization, but that sometimes can make code slower.

What this does: --copt for bazel build passes an option directly to gcc for compiling C and C++ files (but not linking, so you need a different option for cross-file link-time-optimization)

x86-64 gcc defaults to using only SSE2 or older SIMD instructions, so you can run the binaries on any x86-64 system. (See https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html). That's not what you want. You want to make a binary that takes advantage of all the instructions your CPU can run, because you're only running this binary on the system where you built it.

-march=native enables all the options your CPU supports, so it makes -mavx512f -mavx2 -mavx -mfma -msse4.2 redundant. (Also, -mavx2 already enables -mavx and -msse4.2, so Yaroslav's command should have been fine). Also if you're using a CPU that doesn't support one of these options (like FMA), using -mfma would make a binary that faults with illegal instructions.

TensorFlow's ./configure defaults to enabling -march=native, so using that should avoid needing to specify compiler options manually.

-march=native enables -mtune=native, so it optimizes for your CPU for things like which sequence of AVX instructions is best for unaligned loads.

This all applies to gcc, clang, or ICC. (For ICC, you can use -xHOST instead of -march=native.)

As the error notes, the problem is in the line:

if guess[i] == winning_numbers[i]

The error is that your list indices are out of range--that is, you are trying to refer to some index that doesn't even exist. Without debugging your code fully, I would check the line where you are adding guesses based on input:

for i in range(tickets):
    bubble = input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split(" ")
    guess.append(bubble)
print(bubble)

The size of how many guesses you are giving your user is based on

# Prompts the user to enter the number of tickets they wish to play.
tickets = int(input("How many lottery tickets do you want?\n"))

So if the number of tickets they want is less than 5, then your code here

for i in range(5):

if guess[i] == winning_numbers[i]:
    match = match+1

return match

will throw an error because there simply aren't that many elements in the guess list.

Comparing Java 7 and C# 3

(Some features of Java 7 aren't mentioned here, but the using statement advantage of all versions of C# over Java 1-6 has been removed.)

Not all of your summary is correct:

• In Java methods are virtual by default but you can make them final. (In C# they're sealed by default, but you can make them virtual.)
• There are plenty of IDEs for Java, both free (e.g. Eclipse, Netbeans) and commercial (e.g. IntelliJ IDEA)

Beyond that (and what's in your summary already):

• Generics are completely different between the two; Java generics are just a compile-time "trick" (but a useful one at that). In C# and .NET generics are maintained at execution time too, and work for value types as well as reference types, keeping the appropriate efficiency (e.g. a List<byte> as a byte[] backing it, rather than an array of boxed bytes.)
• C# doesn't have checked exceptions
• Java doesn't allow the creation of user-defined value types
• Java doesn't have operator and conversion overloading
• Java doesn't have iterator blocks for simple implemetation of iterators
• Java doesn't have anything like LINQ
• Partly due to not having delegates, Java doesn't have anything quite like anonymous methods and lambda expressions. Anonymous inner classes usually fill these roles, but clunkily.
• Java doesn't have expression trees
• C# doesn't have anonymous inner classes
• C# doesn't have Java's inner classes at all, in fact - all nested classes in C# are like Java's static nested classes
• Java doesn't have static classes (which don't have any instance constructors, and can't be used for variables, parameters etc)
• Java doesn't have any equivalent to the C# 3.0 anonymous types
• Java doesn't have implicitly typed local variables
• Java doesn't have extension methods
• Java doesn't have object and collection initializer expressions
• The access modifiers are somewhat different - in Java there's (currently) no direct equivalent of an assembly, so no idea of "internal" visibility; in C# there's no equivalent to the "default" visibility in Java which takes account of namespace (and inheritance)
• The order of initialization in Java and C# is subtly different (C# executes variable initializers before the chained call to the base type's constructor)
• Java doesn't have properties as part of the language; they're a convention of get/set/is methods
• Java doesn't have the equivalent of "unsafe" code
• Interop is easier in C# (and .NET in general) than Java's JNI
• Java and C# have somewhat different ideas of enums. Java's are much more object-oriented.
• Java has no preprocessor directives (#define, #if etc in C#).
• Java has no equivalent of C#'s ref and out for passing parameters by reference
• Java has no equivalent of partial types
• C# interfaces cannot declare fields
• Java has no unsigned integer types
• Java has no language support for a decimal type. (java.math.BigDecimal provides something like System.Decimal - with differences - but there's no language support)
• Java has no equivalent of nullable value types
• Boxing in Java uses predefined (but "normal") reference types with particular operations on them. Boxing in C# and .NET is a more transparent affair, with a reference type being created for boxing by the CLR for any value type.

This is not exhaustive, but it covers everything I can think of off-hand.

Mike; Everytime I need to modify an XML document I work it this way:

//Here is the variable with which you assign a new value to the attribute
string newValue = string.Empty;
XmlDocument xmlDoc = new XmlDocument();

xmlDoc.Load(xmlFile);

XmlNode node = xmlDoc.SelectSingleNode("Root/Node/Element");
node.Attributes[0].Value = newValue;

xmlDoc.Save(xmlFile);

//xmlFile is the path of your file to be modified

I hope you find it useful

EDIT: I would appreciate it if you do not downvote this answer further. This answer is wrong, but I would rather retain it as a historical note. While it is arguable whether the pytz interface is error-prone, it can do things that dateutil.tz cannot do, especially regarding daylight-saving in the past or in the future. I have honestly recorded my experience in an article "Time zones in Python".

If you are on a Unix-like platform, I would suggest you avoid pytz and look just at /usr/share/zoneinfo. dateutil.tz can utilize the information there.

The following piece of code shows the problem pytz can give. I was shocked when I first found it out. (Interestingly enough, the pytz installed by yum on CentOS 7 does not exhibit this problem.)

import pytz
import dateutil.tz
from datetime import datetime
print((datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('Asia/Shanghai'))
     - datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('UTC')))
     .total_seconds())
print((datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.gettz('Asia/Shanghai'))
     - datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.tzutc()))
     .total_seconds())

-29160.0
-28800.0

I.e. the timezone created by pytz is for the true local time, instead of the standard local time people observe. Shanghai conforms to +0800, not +0806 as suggested by pytz:

pytz.timezone('Asia/Shanghai')
<DstTzInfo 'Asia/Shanghai' LMT+8:06:00 STD>

EDIT: Thanks to Mark Ransom's comment and downvote, now I know I am using pytz the wrong way. In summary, you are not supposed to pass the result of pytz.timezone(…) to datetime, but should pass the datetime to its localize method.

Despite his argument (and my bad for not reading the pytz documentation more carefully), I am going to keep this answer. I was answering the question in one way (how to enumerate the supported timezones, though not with pytz), because I believed pytz did not provide a correct solution. Though my belief was wrong, this answer is still providing some information, IMHO, which is potentially useful to people interested in this question. Pytz's correct way of doing things is counter-intuitive. Heck, if the tzinfo created by pytz should not be directly used by datetime, it should be a different type. The pytz interface is simply badly designed. The link provided by Mark shows that many people, not just me, have been misled by the pytz interface.

An import is required, import scipy.io...

import scipy.io
mat = scipy.io.loadmat('file.mat')

I gone through all the tools mentioned as answer here. But they give repeated, dirty HTML CSS with beautiful face you were staring up on. They don't give you JS.

What I do:

1. First I filter ads which are not require on the page
2. Then , save complete webpage along with linking resources.
3. Remove unnecessary HTML, CSS and JS
4. keep unlinking resources one-by-one carefully.

In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

I think System.Math.Truncate is what you're looking for.

I do not like use pure "a" tag, too much typing. So I come with solution. In view it look

<%: Html.ActionLink(node.Name, "Show", "Browse", 
                    Dic.Route("id", node.Id), Dic.New("data-nodeId", node.Id)) %>

Implementation of Dic class

public static class Dic
{
    public static Dictionary<string, object> New(params object[] attrs)
    {
        var res = new Dictionary<string, object>();
        for (var i = 0; i < attrs.Length; i = i + 2)
            res.Add(attrs[i].ToString(), attrs[i + 1]);
        return res;
    }

    public static RouteValueDictionary Route(params object[] attrs)
    {
        return new RouteValueDictionary(Dic.New(attrs));
    }
}

I use this code:

show-hide button

 <a @click.stop="visualSwitch()"> show hide </a>

show-hide element

<div class="dialog-popup" v-if="visualState" @click.stop=""></div>

script

data () { return {
    visualState: false,
}},
methods: {
    visualSwitch() {
        this.visualState = !this.visualState;
        if (this.visualState)
            document.addEventListener('click', this.visualState);
        else
            document.removeEventListener('click', this.visualState);
    },
},

Update: remove watch; add stop propagation

Your Java file is compiled with a different version (higher compiler version) than the version (lower runtime version) you are trying to run it with.

It is basic understanding that classes compiled with lower versions are expected to run in the later higher versions. But the opposite (compiled with higher compiler version and trying to run it with lower runtime version) is quite not possible sometimes.

Hence you are shown this error, when trying to execute your program. Unsupported major.minor version x.x

Q: I have created an application in Java 7, but when my users try to run it they get an Unsupported major.minor version 51.0 error. What does this mean and what can I do about it?

A: If you compile an application using javac in Java 7, the resulting classfiles will have the 51.0 version number. Versions of Java prior to 7 do not recognize this number, so your users will have to upgrade to Java 7 prior to running your application. If you are not using any Java 7 APIs you can try to compile your application using javac -target 1.6 to create a 1.6-compatible classfile. If your application is deployed using webstart you can specify the minimum version required. For more information, see the docs on Java Web Start and JNLP here. This issue will go away once we trigger autoupdate to Java 7 for end-users currently having Java 6 on their desktops. The timeline for this is not yet determined, we want to give developers time to work out any issues between their code and JDK 7 first.

The existing answers will suit most people, but for those who are looking to add shadows under the fixed header and to the right of the first (fixed) column, here's a working example (pure css):

http://jsbin.com/nayifepaxo/1/edit?html,output

The main trick in getting this to work is using ::after to add shadows to the right of each of the first td in each tr:

tr td:first-child:after {
  box-shadow: 15px 0 15px -15px rgba(0, 0, 0, 0.05) inset;
  content: "";
  position:absolute;
  top:0;
  bottom:0;
  right:-15px;
  width:15px;
}

Took me a while (too long...) to get it all working so I figured I'd share for those who are in a similar situation.

The dependencies must be applied as shown below to solve this issue :

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'

implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support:recyclerview-v7:27.1.0'
}

I render context path to attribute of link tag with id="contextPahtHolder" and then obtain it in JS code. For example:

<html>
    <head>
        <link id="contextPathHolder" data-contextPath="${pageContext.request.contextPath}"/>
    <body>
        <script src="main.js" type="text/javascript"></script>
    </body>
</html>

main.js

var CONTEXT_PATH = $('#contextPathHolder').attr('data-contextPath');
$.get(CONTEXT_PATH + '/action_url', function() {});

If context path is empty (like in embedded servlet container istance), it will be empty string. Otherwise it contains contextPath string

pip itself is just a normal python package. Thus you can install pip with pip.

Of cource, you don't want to affect the system's pip, install it inside a virtualenv.

pip install pip==1.2.1

I was struggling with the same problem and stumbled upon this page. Another solution I came up with would be this :

In your html, echo the session variable (mine here is $_SESSION['origin']) to any element of your choosing : <p id="sessionOrigin"><?=$_SESSION['origin'];?></p>

In your js, using jQuery you can access it like so : $("#sessionOrigin").text();

EDIT: or even better, put it in a hidden input

<input type="hidden" name="theOrigin" value="<?=$_SESSION['origin'];?>"></input>

This question is almost a year old but I have found that if you make a custom comparator for objects you can use Collections.max for an array list of objects.

import java.util.Comparator;

public class compPopulation implements Comparator<Country> {
    public int compare(Country a, Country b) {
        if (a.getPopulation() > b.getPopulation())
            return -1; // highest value first
        if (a.getPopulation() == b.Population())
            return 0;
        return 1;
    }
}
ArrayList<Country> X = new ArrayList<Country>();
// create some country objects and put in the list
Country ZZ = Collections.max(X, new compPopulation());

View the source of the login page. Look for the form HTML tag. Within that tag is something that will look like action= Use that value as $url, not the URL of the form itself.

Also, while you are there, verify the input boxes are named what you have them listed as.

For example, a basic login form will look similar to:

<form method='post' action='postlogin.php'>
    Email Address: <input type='text' name='email'>
    Password: <input type='password' name='password'>
</form>

Using the above form as an example, change your value of $url to:

$url="http://www.myremotesite.com/postlogin.php";

Verify the values you have listed in $postdata:

$postdata = "email=".$username."&password=".$password;

and it should work just fine.

on sql 2008 this is valid

DECLARE @myVariable nvarchar(Max) = 'John said to Emily "Hey there Emily"'
select @myVariable

on sql server 2005, you need to do this

DECLARE @myVariable nvarchar(Max) 
select @myVariable = 'John said to Emily "Hey there Emily"'
select @myVariable

'some+multi+word+string'.replace(/\+/g, ' ');
                                   ^^^^^^

'g' = "global"

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package

import sun.misc.BASE64Encoder;

import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;

and then,

String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );

 public String getAuthantication(String username, String password) {
   String auth = new String(Base64.encode(username + ":" + password));
   return auth;
 }

For VS2019 I was able to signup with my github account:

Then it will send password to your email and you will be able to sign.

If you have to work with file-stream (so no physically saved PDF) like we do and you want to download the PDF without page-reload, the following function works for us:

HTML

<div id="download-helper-hidden-container" style="display:none">
     <form id="download-helper-form" target="pdf-download-output" method="post">
            <input type="hidden" name="downloadHelperTransferData" id="downloadHelperTransferData" />
     </form>
     <iframe id="pdf-helper-output" name="pdf-download-output"></iframe>
</div>

Javascript

var form = document.getElementById('download-helper-form');
$("#downloadHelperTransferData").val(transferData);
form.action = "ServerSideFunctionWhichWritesPdfBytesToResponse";
form.submit();

Due to the target="pdf-download-output", the response is written into the iframe and therefore no page reload is executed, but the pdf-response-stream is output in the browser as a download.

I really like cottsaks solution and think its very clearly explained. my only addition was to alter step 2 as follows

public abstract class MyController : Controller
{

    #region Http404 handling

    protected override void HandleUnknownAction(string actionName)
    {
        //if controller is ErrorController dont 'nest' exceptions
        if(this.GetType() != typeof(ErrorController))
        this.InvokeHttp404(HttpContext);
    }

    public ActionResult InvokeHttp404(HttpContextBase httpContext)
    {
        IController errorController = ObjectFactory.GetInstance<ErrorController>();
        var errorRoute = new RouteData();
        errorRoute.Values.Add("controller", "Error");
        errorRoute.Values.Add("action", "Http404");
        errorRoute.Values.Add("url", httpContext.Request.Url.OriginalString);
        errorController.Execute(new RequestContext(
             httpContext, errorRoute));

        return new EmptyResult();

Basically this stops urls containing invalid actions AND controllers from triggering the exception routine twice. eg for urls such as asdfsdf/dfgdfgd

That is for removing any space that is when you getting text from any text field but if you want to remove space between string you can use

xyz =[xyz.text stringByReplacingOccurrencesOfString:@" " withString:@""];

It will replace empty space with no space and empty field is taken care of by below method:

searchbar.text=[searchbar.text stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceCharacterSet]];

Use CopyOnWriteArrayList
and if you want to remove it, do the following:

for (Iterator<String> it = userList.iterator(); it.hasNext() ;)
{
    if (wordsToRemove.contains(word))
    {
        it.remove();
    }
}

This function will tell you if your string contains ONLY the characters 0123456789.

private bool IsInt(string sVal)
{
    foreach (char c in sVal)
    {
         int iN = (int)c;
         if ((iN > 57) || (iN < 48))
            return false;
    }
    return true;
}

This is different from int.TryParse() which will tell you if your string COULD BE an integer.
eg. " 123\r\n" will return TRUE from int.TryParse() but FALSE from the above function.

...Just depends on the question you need to answer.

 dataType:'jsonp',

You are making a JSONP request, but the server is responding with JSON.

The browser is refusing to try to treat the JSON as JSONP because it would be a security risk. (If the browser did try to treat the JSON as JSONP then it would, at best, fail).

See this question for more details on what JSONP is. Note that is a nasty hack to work around the Same Origin Policy that was used before CORS was available. CORS is a much cleaner, safer, and more powerful solution to the problem.

It looks like you are trying to make a cross-origin request and are throwing everything you can think of at it in one massive pile of conflicting instructions.

You need to understand how the Same Origin policy works.

See this question for an in-depth guide.

Now a few notes about your code:

contentType: 'application/json',

• This is ignored when you use JSONP
• You are making a GET request. There is no request body to describe the type of.
• This will make a cross-origin request non-simple, meaning that as well as basic CORS permissions, you also need to deal with a pre-flight.

Remove that.

 dataType:'jsonp',

• The server is not responding with JSONP.

Remove this. (You could make the server respond with JSONP instead, but CORS is better).

responseType:'application/json',

This is not an option supported by jQuery.ajax. Remove this.

xhrFields: { withCredentials: false },

This is the default. Unless you are setting it to true with ajaxSetup, remove this.

  headers: {
    'Access-Control-Allow-Credentials' : true,
    'Access-Control-Allow-Origin':'*',
    'Access-Control-Allow-Methods':'GET',
    'Access-Control-Allow-Headers':'application/json',
  },

• These are response headers. They belong on the response, not the request.
• This will make a cross-origin request non-simple, meaning that as well as basic CORS permissions, you also need to deal with a pre-flight.

This error is related to web.config file. When web.config is not proper or using some features which is not available in IIS, then this issue will come. In my case, I forgot to install URLRewrite module and was referencing it in web.config. It took some time to find the root cause. I started removing sections one by one and checked, only then i was able to find out the actual issue.

You can generate easily with livegap charts
Select Mulicolors from Bar menu

_{(source: livegap.com)}

** chart library used is chartnew.js modified version of chart.js library
with chartnew.js code will be something like this

var barChartData = {
        labels: ["001", "002", "003", "004", "005", "006", "007"],
        datasets: [
            {
                label: "My First dataset",
                fillColor: ["rgba(0,10,220,0.5)","rgba(220,0,10,0.5)","rgba(220,0,0,0.5)","rgba(120,250,120,0.5)" ],
                strokeColor: "rgba(220,220,220,0.8)", 
                highlightFill: "rgba(220,220,220,0.75)",
                highlightStroke: "rgba(220,220,220,1)",
                data: [20, 59, 80, 81, 56, 55, 40]
            }
        ]
    };

You can easily convert the string data type to numerical data type.
Don't forget to change collectionName & FieldName.
for ex : CollectionNmae : Users & FieldName : Contactno.

Try this query..

db.collectionName.find().forEach( function (x) {
x.FieldName = parseInt(x.FieldName);
db.collectionName.save(x);
});

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

if (   ($name eq "tom" and $password eq "123!")
    or ($name eq "frank" and $password eq "321!")) {

    print "You have gained access.";
}
else {
    print "Access denied!";
}

You should probably use either DateTime.ParseExact or DateTime.TryParseExact instead. They allow you to specify specific formats. I personally prefer the Try-versions since I think they produce nicer code for the error cases.

Here is a little research that explored RDBMS vs NoSQL using MySQL vs Mongo, the conclusions were inline with @Sean Reilly's response. In short, the benefit comes from the design, not some raw speed difference. Conclusion on page 35-36:

RDBMS vs NoSQL: Performance and Scaling Comparison

The project tested, analysed and compared the performance and scalability of the two database types. The experiments done included running different numbers and types of queries, some more complex than others, in order to analyse how the databases scaled with increased load. The most important factor in this case was the query type used as MongoDB could handle more complex queries faster due mainly to its simpler schema at the sacrifice of data duplication meaning that a NoSQL database may contain large amounts of data duplicates. Although a schema directly migrated from the RDBMS could be used this would eliminate the advantage of MongoDB’s underlying data representation of subdocuments which allowed the use of less queries towards the database as tables were combined. Despite the performance gain which MongoDB had over MySQL in these complex queries, when the benchmark modelled the MySQL query similarly to the MongoDB complex query by using nested SELECTs MySQL performed best although at higher numbers of connections the two behaved similarly. The last type of query benchmarked which was the complex query containing two JOINS and and a subquery showed the advantage MongoDB has over MySQL due to its use of subdocuments. This advantage comes at the cost of data duplication which causes an increase in the database size. If such queries are typical in an application then it is important to consider NoSQL databases as alternatives while taking in account the cost in storage and memory size resulting from the larger database size.

As stated by pnt you can have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.

Taking it further from there: Here's how it might be possible to set any runtime parameters for each of those installations:

You can run javacpl.exe or javacpl.cpl of the respective Java-version itself (bin-folder). The specific control panel opens fine. Adding parameters there is possible.

Another solution would be to use table aliases, like so:

SELECT p1.id, p2.id, p1.address
FROM list AS p1, list AS p2
WHERE p1.address = p2.address
AND p1.id != p2.id

All you're really doing in this case is taking the original list table, creating two pretend tables -- p1 and p2 -- out of that, and then performing a join on the address column (line 3). The 4th line makes sure that the same record doesn't show up multiple times in your set of results ("duplicate duplicates").

In my situation, the Oracle 11.2 32-bit client was installed on my 64-bit Windows 2008 R2 OS.

My solution: In the Advanced Settings for the Application Pool assigned to my ASP.NET application, I set Enable 32-Bit Applications to True.

Please see below for the standalone .ashx test script that I used to test the ability to connect to Oracle. Before making the Application Pool change, its response was:

[Running as 64-bit] Connection failed.

...and after the Application Pool change:

[Running as 32-bit] Connection succeeded.

WScript.exe exists in two versions, one in C:\Windows\System32\ and the other in C:\Windows\SysWOW64\ directories. They run respectively in 64 bits and 32 bits (against immediate logic but true).

You may add the following code at the beginning of your script so that it automatically starts again in 32 bits if it detects that it's called in 64 bits.

Note that it transmits the arguments if it calls itself to switch to 64 bits.

' C:\Windows\System32\WScript.exe = WScript.exe
Dim ScriptHost : ScriptHost = Mid(WScript.FullName, InStrRev(WScript.FullName, "\") + 1, Len(WScript.FullName))

Dim oWs : Set oWs = CreateObject("WScript.Shell")
Dim oProcEnv : Set oProcEnv = oWs.Environment("Process")

' Am I running 64-bit version of WScript.exe/Cscript.exe? So, call script again in x86 script host and then exit.
If InStr(LCase(WScript.FullName), LCase(oProcEnv("windir") & "\System32\")) And oProcEnv("PROCESSOR_ARCHITECTURE") = "AMD64" Then
    ' rebuild arguments
    If Not WScript.Arguments.Count = 0 Then
        Dim sArg, Arg
        sArg = ""
        For Each Arg In Wscript.Arguments
              sArg = sArg & " " & """" & Arg & """"
        Next
    End If

    Dim sCmd : sCmd = """" &  oProcEnv("windir") & "\SysWOW64\" & ScriptHost & """" & " """ & WScript.ScriptFullName & """" & sArg
    'WScript.Echo "Call " & sCmd
    oWs.Run sCmd
    WScript.Quit
End If

It is a 32bit declaration. If you type at the top of an assembly file the statement [bits 32], then you don't need to type DWORD PTR. So for example:

[bits 32]
.

and  [ebp-4], 0

Hello every one thanks for the help below is the working code for my question

$("#TableView tr.item").each(function() { 
    var quantity1=$(this).find("input.name").val(); 
    var quantity2=$(this).find("input.id").val(); 
});

To take input " long int " and output " long int " in C is :

long int n;
scanf("%ld", &n);
printf("%ld", n);

To take input " long long int " and output " long long int " in C is :

long long int n;
scanf("%lld", &n);
printf("%lld", n);

Hope you've cleared..

I know that my answer is kind of overlapping with some of the other answer, but this is a complete solution that has some advantages. This works on Tomcat 8:

1. The main application is served from the root
2. The deployment of war files through the web interface is maintained.
3. The main application will run on port 80 while only the admins have access to the managment folders (I realize that *nix systems require superuser for binding to 80, but on windows this is not an issue).

This means that you only have to restart the tomcat once, and after updated war files can be deployed without a problem.

Step 1: In the server.xml file, find the connector entry and replace it with:

<Connector 
    port="8080"
    protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8443" />

<Connector
    port="80"
    protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8443" />

Step 2: Define contexts within the <Host ...> tag:

<Context path="/" docBase="CAS">
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
<Context path="/ROOT" docBase="ROOT">
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
<Context path="/manager" docBase="manager" privileged="true">
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
<Context path="/host-manager" docBase="host-manager" privileged="true">
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>

Note that I addressed all apps in the webapp folder. The first effectively switch the root and the main app from position. ROOT is now on http://example.com/ROOT and the the main application is on http://example.com/. The webapps that are password protected require the privileged="true" attribute.

When you deploy a CAS.war file that matches with the root (<Context path="/" docBase="CAS"> you have to reload that one in the admin panel as it does not refresh with the deployment.

Do not include the <Context path="/CAS" docBase="CAS"> in your contexts as it disables the manager option to deploy war files. This means that you can access the app in two ways: http://example.com/ and http://example.com/APP/

Step 3: In order to prevent unwanted access to the root and manager folder, add a valve to those context tags like this:

<Context path="/manager" docBase="manager" privileged="true">
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
        addConnectorPort="true"
        allow="143\.21\.2\.\d+;8080|127\.0\.0\.1;8080|::1;8080|0:0:0:0:0:0:0:1;8080"/>
</Context>

This essentially limits access to the admin web app folder to people from my own domain (fake IP address) and localhost when they use the default port 8080 and maintains the ability to dynamically deploy the war files through the web interface.

If you want to use this for multiple apps that are using different IP addresses, you can add the IP address to the connector (address="143.21.2.1").

If you want to run multiple web apps from the root, you can duplicate the Service tag (use a different name for the second) and change the docbase of the <Context path="/" docBase="CAS"> to for example <Context path="/" docBase="ICR">.

A Collection is not a necessarily ordered set of elements so there may not be a concept of the "last" element. If you want something that's ordered, you can use a SortedSet which has a last() method. Or you can use a List and call mylist.get(mylist.size()-1);

If you really need the last element you should use a List or a SortedSet. But if all you have is a Collection and you really, really, really need the last element, you could use toArray() or you could use an Iterator and iterate to the end of the list.

For example:

public Object getLastElement(final Collection c) {
    final Iterator itr = c.iterator();
    Object lastElement = itr.next();
    while(itr.hasNext()) {
        lastElement = itr.next();
    }
    return lastElement;
}

For a time difference, note that the calendar starts at 01.01.1970, 01:00, not at 00:00. If you're using java.util.Date and java.text.SimpleDateFormat, you will have to compensate for 1 hour:

long start = System.currentTimeMillis();
long end = start + (1*3600 + 23*60 + 45) * 1000 + 678; // 1 h 23 min 45.678 s
Date timeDiff = new Date(end - start - 3600000); // compensate for 1h in millis
SimpleDateFormat timeFormat = new SimpleDateFormat("H:mm:ss.SSS");
System.out.println("Duration: " + timeFormat.format(timeDiff));

This will print:

Duration: 1:23:45.678

The following code creates a control which you will be able to use like a normal TextBox however it will only take a positive double as an input:

In the XAML you'll be able to use this control like so:

<local:UnsignedDoubleBox/>

In the C# code add the following inside the current namespace:

public class UnsignedDoubleBox : TextBox
    {
        public UnsignedDoubleBox()
        {
            this.PreviewTextInput += defaultPreviewTextInput;
            DataObject.AddPastingHandler(this, defaultTextBoxPasting);
        }

        private bool IsTextAllowed(TextBox textBox, String text)
        {
            //source: https://stackoverflow.com/questions/23397195/in-wpf-does-previewtextinput-always-give-a-single-character-only#comment89374810_23406386
            String newText = textBox.Text.Insert(textBox.CaretIndex, text);
            double res;
            return double.TryParse(newText, out res) && res >= 0;
        }
        //source: https://stackoverflow.com/a/1268648/13093413
        private void defaultTextBoxPasting(object sender, DataObjectPastingEventArgs e)
        {
            if (e.DataObject.GetDataPresent(typeof(String)))
            {
                String text = (String)e.DataObject.GetData(typeof(String));

                if (!IsTextAllowed((TextBox)sender, text))
                {
                    e.CancelCommand();
                }
            }
            else
            {
                e.CancelCommand();
            }
        }

        private void defaultPreviewTextInput(object sender, TextCompositionEventArgs e)
        {

            if (IsTextAllowed((TextBox)sender, e.Text))
            {
                e.Handled = false;
            }
            else
            {
                e.Handled = true;
            }
        }

    }

For me below worked:

Step 1: Downloaded and installed the web Installer exe from https://www.microsoft.com/en-us/download/details.aspx?id=48137 on the application server. Rebooted the application server after installation was completed.

Step 2: Added below changes in the web.config

<system.web>
    <compilation targetFramework="4.6"/> <!-- Changed framework 4.0 to 4.6 -->
    <!--Added this httpRuntime -->
    <httpRuntime targetFramework="4.6" />
</system.web>

Step 3: After completing step 1 and 2, it gave an error, "WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive)" and to resolve this error, I added below key in appsettings in my web.config file

<appSettings>
      <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

The long boring solution, which is not involved with CLI, you can manually navigate to:

your local repo folder ? .git folder (hidden) ? config file

then choose your text editor to open it and look for url located under the [remote "origin"] section.

the default encoding of a HTTP POST is ISO-8859-1.

else you have to look at the Content-Type header that will then look like

Content-Type: application/x-www-form-urlencoded ; charset=UTF-8

You can maybe declare your form with

<form enctype="application/x-www-form-urlencoded;charset=UTF-8">

or

<form accept-charset="UTF-8">

to force the encoding.

Is your link to another web page? If so, perhaps you could put the variable in the query string and set the session variable when the page being linked to is loaded.

So the link looks like this:

<a href="home.php?variable=value" name="home">home</a>

And the homge page would parse the query string and set the session variable.

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

The simplest way using ClosedXml.

Imports ClosedXML.Excel

var dataList = new List<string>() { "a", "b", "c" };
var workbook = new XLWorkbook();     //creates the workbook
var wsDetailedData = workbook.AddWorksheet("data"); //creates the worksheet with sheetname 'data'
wsDetailedData.Cell(1, 1).InsertTable(dataList); //inserts the data to cell A1 including default column name
workbook.SaveAs(@"C:\data.xlsx"); //saves the workbook

A static variable inside a function has a lifespan as long as your program runs. It won't be allocated every time your function is called and deallocated when your function returns.

This will add a global function to access to the queryString variables as a map.

// -------------------------------------------------------------------------------------
// Add function for 'window.location.query( [queryString] )' which returns an object
// of querystring keys and their values. An optional string parameter can be used as
// an alternative to 'window.location.search'.

// Add function for 'window.location.query.makeString( object, [addQuestionMark] )'
// which returns a queryString from an object. An optional boolean parameter can be
// used to toggle a leading question mark.
// -------------------------------------------------------------------------------------
if (!window.location.query) {
    window.location.query = function (source) {

In[1]: def myfunc(a=1, b=2):
In[2]:    print(a, b)

In[3]: mydict = {'a': 100, 'b': 200}

In[4]: myfunc(**mydict)
100 200

A few extra details that might be helpful to know (questions I had after reading this and went and tested):

1. The function can have parameters that are not included in the dictionary
2. You can not override a parameter that is already in the dictionary
3. The dictionary can not have parameters that aren't in the function.

Examples:

Number 1: The function can have parameters that are not included in the dictionary

In[5]: mydict = {'a': 100}
In[6]: myfunc(**mydict)
100 2

Number 2: You can not override a parameter that is already in the dictionary

In[7]: mydict = {'a': 100, 'b': 200}
In[8]: myfunc(a=3, **mydict)

TypeError: myfunc() got multiple values for keyword argument 'a'

Number 3: The dictionary can not have parameters that aren't in the function.

In[9]:  mydict = {'a': 100, 'b': 200, 'c': 300}
In[10]: myfunc(**mydict)

TypeError: myfunc() got an unexpected keyword argument 'c'

As requested in comments, a solution to Number 3 is to filter the dictionary based on the keyword arguments available in the function:

In[11]: import inspect
In[12]: mydict = {'a': 100, 'b': 200, 'c': 300}
In[13]: filtered_mydict = {k: v for k, v in mydict.items() if k in [p.name for p in inspect.signature(myfunc).parameters.values()]}
In[14]: myfunc(**filtered_mydict)
100 200

Another option is to accept (and ignore) additional kwargs in your function:

In[15]: def myfunc2(a=None, **kwargs):
In[16]:    print(a)

In[17]: mydict = {'a': 100, 'b': 200, 'c': 300}

In[18]: myfunc2(**mydict)
100

Notice further than you can use positional arguments and lists or tuples in effectively the same way as kwargs, here's a more advanced example incorporating both positional and keyword args:

In[19]: def myfunc3(a, *posargs, b=2, **kwargs):
In[20]:    print(a, b)
In[21]:    print(posargs)
In[22]:    print(kwargs)

In[23]: mylist = [10, 20, 30]
In[24]: mydict = {'b': 200, 'c': 300}

In[25]: myfunc3(*mylist, **mydict)
10 200
(20, 30)
{'c': 300}

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

The type of expression

" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'"

is std::string. However function system has declaration

int system(const char *s);

that is it accepts an argumnet of type const char *

There is no conversion operator that would convert implicitly an object of type std::string to object of type const char *.

Nevertheless class std::string has two functions that do this conversion explicitly. They are c_str() and data() (the last can be used only with compiler that supports C++11)

So you can write

string name = "john";

system( (" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str() );

There is no need to use an intermediate variable for the expression.

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

To ignore a field, annotate it with @Transient so it will not be mapped by hibernate.

but then jackson will not serialize the field when converting to JSON.

If you need mix JPA with JSON(omit by JPA but still include in Jackson) use @JsonInclude :

@JsonInclude()
@Transient
private String token;

TIP:

You can also use JsonInclude.Include.NON_NULL and hide fields in JSON during deserialization when token == null:

@JsonInclude(JsonInclude.Include.NON_NULL)
@Transient
private String token;

These problems are caused by the use of the same object at the same two classes. Objects used does not contain new method has been added that the new object class contains.

There is a free and easy to use PDF class to create PDF documents. It's called FPDF. In combination with FPDI (http://www.setasign.de/products/pdf-php-solutions/fpdi) it is even possible to edit PDF documents. The following code shows how to use FPDF and FPDI to fill an existing gift coupon with the user data.

require_once('fpdf.php'); 
require_once('fpdi.php'); 
$pdf = new FPDI();

$pdf->AddPage(); 

$pdf->setSourceFile('gift_coupon.pdf'); 
// import page 1 
$tplIdx = $this->pdf->importPage(1); 
//use the imported page and place it at point 0,0; calculate width and height
//automaticallay and ajust the page size to the size of the imported page 
$this->pdf->useTemplate($tplIdx, 0, 0, 0, 0, true); 

// now write some text above the imported page 
$this->pdf->SetFont('Arial', '', '13'); 
$this->pdf->SetTextColor(0,0,0);
//set position in pdf document
$this->pdf->SetXY(20, 20);
//first parameter defines the line height
$this->pdf->Write(0, 'gift code');
//force the browser to download the output
$this->pdf->Output('gift_coupon_generated.pdf', 'D');

In SWT you need not be in a listener to get at the mouse location. The Display object has the method getCursorLocation().

In vanilla SWT/JFace, call Display.getCurrent().getCursorLocation().

In an RCP application, call PlatformUI.getWorkbench().getDisplay().getCursorLocation().

For SWT applications, it is preferable to use getCursorLocation() over the MouseInfo.getPointerInfo() that others have mentioned, as the latter is implemented in the AWT toolkit that SWT was designed to replace.

Using CLI:

Server version:

$ postgres -V  # Or --version.  Use "locate bin/postgres" if not found.
postgres (PostgreSQL) 9.6.1
$ postgres -V | awk '{print $NF}'  # Last column is version.
9.6.1
$ postgres -V | egrep -o '[0-9]{1,}\.[0-9]{1,}'  # Major.Minor version
9.6

If having more than one installation of PostgreSQL, or if getting the "postgres: command not found" error:

$ locate bin/postgres | xargs -i xargs -t '{}' -V  # xargs is intentionally twice.
/usr/pgsql-9.3/bin/postgres -V 
postgres (PostgreSQL) 9.3.5
/usr/pgsql-9.6/bin/postgres -V 
postgres (PostgreSQL) 9.6.1

If locate doesn't help, try find:

$ sudo find / -wholename '*/bin/postgres' 2>&- | xargs -i xargs -t '{}' -V  # xargs is intentionally twice.
/usr/pgsql-9.6/bin/postgres -V 
postgres (PostgreSQL) 9.6.1

Although postmaster can also be used instead of postgres, using postgres is preferable because postmaster is a deprecated alias of postgres.

Client version:

As relevant, login as postgres.

$ psql -V  # Or --version
psql (PostgreSQL) 9.6.1

If having more than one installation of PostgreSQL:

$ locate bin/psql | xargs -i xargs -t '{}' -V  # xargs is intentionally twice.
/usr/bin/psql -V 
psql (PostgreSQL) 9.3.5
/usr/pgsql-9.2/bin/psql -V 
psql (PostgreSQL) 9.2.9
/usr/pgsql-9.3/bin/psql -V 
psql (PostgreSQL) 9.3.5

Using SQL:

Server version:

=> SELECT version();
                                                   version                                                    
--------------------------------------------------------------------------------------------------------------
 PostgreSQL 9.2.9 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4), 64-bit

=> SHOW server_version;
 server_version 
----------------
 9.2.9

=> SHOW server_version_num;
 server_version_num 
--------------------
 90209

If more curious, try => SHOW all;.

Client version:

For what it's worth, a shell command can be executed within psql to show the client version of the psql executable in the path. Note that the running psql can potentially be different from the one in the path.

=> \! psql -V
psql (PostgreSQL) 9.2.9

Be aware that this property isn't as useful as many people think it is. Just because your app is running on a Windows machine, for example, doesn't mean the file it's reading will be using Windows-style line separators. Many web pages contain a mixture of "\n" and "\r\n", having been cobbled together from disparate sources. When you're reading text as a series of logical lines, you should always look for all three of the major line-separator styles: Windows ("\r\n"), Unix/Linux/OSX ("\n") and pre-OSX Mac ("\r").

When you're writing text, you should be more concerned with how the file will be used than what platform you're running on. For example, if you expect people to read the file in Windows Notepad, you should use "\r\n" because it only recognizes the one kind of separator.

Press Ctrl+C

When you start the server it mentions this in the startup text.

You need to create your own converter and implement it before making a GET request.

RestTemplate  restTemplate = new RestTemplate();

List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();        

MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));         
messageConverters.add(converter);  
restTemplate.setMessageConverters(messageConverters);    

Just use var = var1 var2 and it will automatically concatenate the vars var1 and var2:

awk '{new_var=$1$2; print new_var}' file

You can put an space in between with:

awk '{new_var=$1" "$2; print new_var}' file

Which in fact is the same as using FS, because it defaults to the space:

awk '{new_var=$1 FS $2; print new_var}' file

Test

$ cat file
hello how are you
i am fine
$ awk '{new_var=$1$2; print new_var}' file
hellohow
iam
$ awk '{new_var=$1 FS $2; print new_var}' file
hello how
i am

You can play around with it in ideone: http://ideone.com/4u2Aip

You can use Len(StrFile) > 0 in loop check statement !

Sub openMyfile()

    Dim Source As String
    Dim StrFile As String

    'do not forget last backslash in source directory.
    Source = "E:\Planning\03\"
    StrFile = Dir(Source)

    Do While Len(StrFile) > 0                        
        Workbooks.Open Filename:=Source & StrFile
        StrFile = Dir()
    Loop
End Sub

The same as in JavaScript, using Array.prototype.indexOf():

console.log(channelArray.indexOf('three') > -1);

Or using ECMAScript 2016 Array.prototype.includes():

console.log(channelArray.includes('three'));

Note that you could also use methods like showed by @Nitzan to find a string. However you wouldn't usually do that for a string array, but rather for an array of objects. There those methods were more sensible. For example

const arr = [{foo: 'bar'}, {foo: 'bar'}, {foo: 'baz'}];
console.log(arr.find(e => e.foo === 'bar')); // {foo: 'bar'} (first match)
console.log(arr.some(e => e.foo === 'bar')); // true
console.log(arr.filter(e => e.foo === 'bar')); // [{foo: 'bar'}, {foo: 'bar'}]

Reference

Array.find()

Array.some()

Array.filter()

If your application has minimum sdk version 16 then you can use finishAffinity()

Finish this activity as well as all activities immediately below it in the current task that have the same affinity.

This is work for me In Top Payment screen remove all back-stack activits,

 @Override
public void onBackPressed() {
         finishAffinity();
        startActivity(new Intent(PaymentDoneActivity.this,Home.class));
    } 

http://developer.android.com/reference/android/app/Activity.html#finishAffinity%28%29

There are many answers and all are correct as well. But unfortunately none of them have a clear explanation.

The following works for a non-primary key mapping as well.

Let's say we have parent table A with column 1 and another table, B, with column 2 which references column 1:

@ManyToOne
@JoinColumn(name = "TableBColumn", referencedColumnName = "TableAColumn")
private TableA session_UserName;

@ManyToOne
@JoinColumn(name = "bok_aut_id", referencedColumnName = "aut_id")
private Author bok_aut_id;

server.session.timeout in the application.properties file is now deprecated. The correct setting is:

server.servlet.session.timeout=60s

Also note that Tomcat will not allow you to set the timeout any less than 60 seconds. For details about that minimum setting see https://github.com/spring-projects/spring-boot/issues/7383.

the over partition keyword is as if we are partitioning the data by client_id creation a subset of each client id

select client_id, operation_date,
       row_number() count(*) over (partition by client_id order by client_id ) as operationctrbyclient
from client_operations e
order by e.client_id;

this query will return the number of operations done by the client_id

Using ES6 Map (pretty well supported), you can try this:

var arr = [_x000D_
    { key: 'foo', val: 'bar' },_x000D_
    { key: 'hello', val: 'world' }_x000D_
];_x000D_
_x000D_
var result = new Map(arr.map(i => [i.key, i.val]));_x000D_
_x000D_
// When using TypeScript, need to specify type:_x000D_
// var result = arr.map((i): [string, string] => [i.key, i.val])_x000D_
_x000D_
// Unfortunately maps don't stringify well.  This is the contents in array form._x000D_
console.log("Result is: " + JSON.stringify([...result])); _x000D_
// Map {"foo" => "bar", "hello" => "world"}

Simpler yet:

idx = (-arr).argsort()[:n]

where n is the number of maximum values.

Look out for conflicting references. Even after a clean and rebuild, conflicting references will still cause a problem. My problem was between AForge and Accord. I removed both of the references, and re-added the references re-choosing the particular reference (particular to my case, just Accord).

I'm using the following function for that; it's an adaptation from one of the man entries in the fputscsv comments. And you'll probably want to flatten that array; not sure what happens if you pass in a multi-dimensional one.

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

This is for GridView.

 grid.Rows[0].Cells[1].ReadOnly = true;

• A ref variable needs to be initialized before passing it in.
• An out variable needs to be set in your function implementation
• out parameters can be thought of as additional return variables (not input)
• ref parameters can be thought of as both input and output variables.

MyModelVm.cs

public class MyModelVm
{
    public HttpStatusCode StatusCode { get; set; }
}

Index.cshtml

@model MyNamespace.MyModelVm
@functions
{
    string GetErrorMessage()
    {
        var isNotFound = Model.StatusCode == HttpStatusCode.NotFound;
        string errorMessage;
        if (isNotFound)
        {
            errorMessage = Resources.NotFoundMessage;
        }
        else
        {
            errorMessage = Resources.GeneralErrorMessage
        }

        return errorMessage;
    }
}

<div>
    @GetErrorMessage()
</div>

I solved it with my own function. If you want to update specified field in document you need to address it clearly.

Example:

{
    _id : ...,
    some_key: { 
        param1 : "val1",
        param2 : "val2",
        param3 : "val3"
    }
}

If you want to update param2 only, it's wrong to do:

db.collection.update(  { _id:...} , { $set: { some_key : new_info  } }  //WRONG

You must use:

db.collection.update(  { _id:...} , { $set: { some_key.param2 : new_info  } } 

So i wrote a function something like that:

function _update($id, $data, $options=array()){

    $temp = array();
    foreach($data as $key => $value)
    {
        $temp["some_key.".$key] = $value;
    } 

    $collection->update(
        array('_id' => $id),
        array('$set' => $temp)
    );

}

_update('1', array('param2' => 'some data'));

PowerShell 3+

# This is an automatic variable set to the current file's/module's directory
$PSScriptRoot

PowerShell 2

Prior to PowerShell 3, there was not a better way than querying the MyInvocation.MyCommand.Definition property for general scripts. I had the following line at the top of essentially every PowerShell script I had:

$scriptPath = split-path -parent $MyInvocation.MyCommand.Definition

All those results generate garbage in a zealous attempt to handle more than two arguments. I'd be curious to see how they perform compared to good 'ol:

def max (a,b)
  a>b ? a : b
end

which is, by-the-way, my official answer to your question.

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

I prefer way of "Rosdi Kasim" as that's doesn't require detail configuration on the IP.

I will definitely forget it again when I try to up another server again.

Keep It Simple Stupid (KISS) by simply enable the Sql Server Browser service, then add the \SQLEXPRESS behind the IP when you connect the server.

Direct using IP without "\SQLEXPRESS" was my point of failure as it doesn't use the default port.

Thanks.

A try block has just one mandatory clause: The try statement. The except, else and finally clauses are optional and based on user preference.

finally: Before Python leaves the try statement, it will run the code in the finally block under any conditions, even if it's ending the program. E.g., if Python ran into an error while running code in the except or else block, the finally block will still be executed before stopping the program.

FAST way!

A friend of mine has a series of blog posts that provide an illustration for why you can't do this. He creates function that return an IEnumerable where each iteration returns the next prime number, all the way to ulong.MaxValue, and the next item isn't calculated until you ask for it. Quick, pop question: how many items are returned?

Here are the posts, but they're kind of long:

1. Beyond Loops (provides an initial EnumerableUtility class used in the other posts)
2. Applications of Iterate (Initial implementation)
3. Crazy Extention Methods: ToLazyList (Performance optimizations)

This worked for me:

• Go to the project folder in CLI and type npm install.Go for a similar command if using yarn etc.

• Then type npm start if you are using Npm. Go for a similar command if using yarn etc.

• The file starts working

The simplest solution is to define the row limit and execute. This is done for safety purposes.

my_var: the variable declared

VAR: the variable, whose value is to be checked

param_1, param_2: values of the variable VAR

value_1, value_2, value_3: the values to be assigned to my_var according to the values of my_var

my_var: "{{ 'value_1' if VAR == 'param_1' else 'value_2' if VAR == 'param_2' else 'value_3' }}"

Try to set more reasonable logging level. Setting logging level to info means that only log event at info or higher level (warn, error and fatal) are logged, that is debug logging events are ignored.

log4j.logger.org.hibernate=info

or in XML version of log4j config file:

<logger name="org.hibernate">
  <level value="info"/> 
</logger>

$.post does not work if you have CORS (Cross Origin Resource Sharing) issue. Try to use $.ajax in following format:

$.ajax({
        url: someurl,
        contentType: 'application/json',
        data: requestInJSONFormat,
        headers: { 'Access-Control-Allow-Origin': '*' },
        dataType: 'json',
        type: 'POST',
        async: false,
        success: function (Data) {...}
});

Andy E. gave a good answer.

I would add, if you feel to select all the childs in some special selector (this need happened to me recently), you can apply the method "getElementsByTagName()" on any DOM object you want.

For an example, I needed to just parse "visual" part of the web page, so I just made this

var visualDomElts = document.body.getElementsByTagName('*');

This will never take in consideration the head part.

In my case I had to make a POST request, which had information sent through the header, and also a file sent using a FormData object.

I made it work using a combination of some of the answers here, so basically what ended up working was having this five lines in my Ajax request:

 contentType: "application/octet-stream",
 enctype: 'multipart/form-data',
 contentType: false,
 processData: false,
 data: formData,

Where formData was a variable created like this:

 var file = document.getElementById('uploadedFile').files[0];
 var form = $('form')[0];
 var formData = new FormData(form);
 formData.append("File", file);

Just add this npm script to the package.json file in the root folder.

{
  ...
  "scripts": {
    ...
    "start": "react-scripts start", // or whatever else depends on your project
    "dev": "(cd server && npm run start) & (cd ../client && npm run start)"
  }
}

In Django

1 : we have default field with name "id" which is auto increment.
2 : You can define a auto increment field using AutoField field.

class Order(models.Model):
    auto_increment_id = models.AutoField(primary_key=True)
    #you use primary_key = True if you do not want to use default field "id" given by django to your model

In actionPerformed(ActionEvent e) you call encrypt(), which is declared to throw Exception. However, actionPerformed neither catches this Exception (with try/catch around the call to encrypt()) nor declares that it throws Exception itself.

Your encrypt method, however, does not truly throw Exception. It swallows all Exceptions without even as much as logging a complaint. (Bad practice and bad style!)

Also, your encrypt method does the following:

public static byte[] encrypt(String toEncrypt) throws Exception {
  try{
    ....
    return encrypted; // HERE YOU CORRECTLY RETURN A VALUE
  } catch(Exception e) {
  }
  // YOU DO NOT RETURN ANYTHING HERE
}

That is, if you do catch any Exception, you discard it silently and then fall off the bottom of your encrypt method without actually returning anything. This won't compile (as you see), because a method that is declared to return a value must either return a value or throw an Exception for every single possible code path.

One "dimension" of this topic has been left out yet it's very important: there are times when the "best practices" have to come into terms with the plaform we are implementing or augmenting with REST capabilities.

Practical example:

Many web applications nowadays implement the MVC (Model, View, Controller) architecture. They assume a certain standard path is provided, even more so when those web applications come with an "Enable SEO URLs" option.

Just to mention a fairly famous web application: an OpenCart e-commerce shop. When the admin enables the "SEO URLs" it expects said URLs to come in a quite standard MVC format like:

http://www.domain.tld/special-offers/list-all?limit=25

Where

• special-offers is the MVC controller that shall process the URL (showing the special-offers page)

• list-all is the controller's action or function name to call. (*)

• limit=25 is an option, stating that 25 items will be shown per page.

(*) list-all is a fictious function name I used for clarity. In reality, OpenCart and most MVC frameworks have a default, implied (and usually omitted in the URL) index function that gets called when the user wants a default action to be performed. So the real world URL would be:

http://www.domain.tld/special-offers?limit=25

With a now fairly standard application or frameworkd structure similar to the above, you'll often get a web server that is optimized for it, that rewrites URLs for it (the true "non SEOed URL" would be: http://www.domain.tld/index.php?route=special-offers/list-all&limit=25).

Therefore you, as developer, are faced into dealing with the existing infrastructure and adapt your "best practices", unless you are the system admin, know exactly how to tweak an Apache / NGinx rewrite configuration (the latter can be nasty!) and so on.

So, your REST API would often be much better following the referring web application's standards, both for consistency with it and ease / speed (and thus budget saving).

To get back to the practical example above, a consistent REST API would be something with URLs like:

http://www.domain.tld/api/special-offers-list?from=15&limit=25

or (non SEO URLs)

http://www.domain.tld/index.php?route=api/special-offers-list?from=15&limit=25

with a mix of "paths formed" arguments and "query formed" arguments.

I was able to work around it by running mvn install:install-file with -Dpackaging=class. Then adding entry to POM as described here:

In my case, when I'm in an activity that extends from AppCompatActivity, it did not work(Activity) getApplicationContext (), I just putthis in its place.

function abc() {
    var color = document.getElementById("test").style.color;
    color = (color=="red") ? "black" : "red" ;
    document.getElementById("test").style.color= color;
}

You can encapsulate this quite nicely in a func similar to what is below.

package main

import (
        "bufio"
        "fmt"
        "os"
)

func main() {
        fmt.Println(prompt())
}

func prompt(params ...string) string {
        prompt := ": "
        if len(params) > 0 {
                prompt = params[0]
        }
        reader := bufio.NewReader(os.Stdin)
        fmt.Print(prompt)
        text, _ := reader.ReadString('\n')
        return text
}

In this example, the prompt by default has a colon and a space in front of it . . .

: 

. . . however you can override that by supplying a parameter to the prompt function.

prompt("Input here -> ")

This will result in a prompt like below.

Input here ->

use return before calling the function, while you click the submit button, two events(form posting as you used submit button and function call for onclick) will happen, to prevent form posting you have to return false, you have did it, also you have to specify the return i.e, to expect a value from the function,

this is a code:

input type="submit" name="continue" value="submit" onClick="**return** checkform();"

IoC/DI is a design concept, but unfortunately it's often taken as a concept that applies to certain languages (or typing systems). I'd love to see dependency injection containers become far more popular in Python. There's Spring, but that's a super-framework and seems to be a direct port of the Java concepts without much consideration for "The Python Way."

Given Annotations in Python 3, I decided to have a crack at a full featured, but simple, dependency injection container: https://github.com/zsims/dic . It's based on some concepts from a .NET dependency injection container (which IMO is fantastic if you're ever playing in that space), but mutated with Python concepts.

With bootstrap 3 the best way to go about achieving what you want is ...with offsetting columns. Please see these examples for more detail:
http://getbootstrap.com/css/#grid-offsetting

In short, and without seeing your divs here's an example what might help, without using any custom classes. Just note how the "col-6" is used and how half of that is 3 ...so the "offset-3" is used. Splitting equally will allow the centered spacing you're going for:

<div class="container">
<div class="col-sm-6 col-sm-offset-3">
your centered, floating column
</div></div>

$(document).ready(function()
{
    $('#yourtext').keyup(function()
    {
        $(this).val($(this).val().toUpperCase());
    });
});

<textarea id="yourtext" rows="5" cols="20"></textarea>

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

Courtesy of Microsoft Excel: 

That site makes use of the "fragment" part of a url: the stuff after the "#". This is not sent to the server by the browser as part of the GET request, but can be used to store page state. So yes you can change the fragment without causing a page refresh or reload. When the page loads, your javascript reads this fragment and updates the page content appropriately, fetching data from the server via ajax requests as required. To read the fragment in js:

var fragment = location.hash;

but note that this value will include the "#" character at the beginning. To set the fragment:

location.hash = "your_state_data";

Use the apache commons-lang3 lib

import org.apache.commons.lang3.exception.ExceptionUtils;

//...

String[] ss = ExceptionUtils.getRootCauseStackTrace(e);
logger.error(StringUtils.join(ss, System.lineSeparator()));

If u want to Selected text clear then using to this code i will make by my self ;)

If e.KeyCode = Keys.Delete Then
    TextBox1.SelectedText = ""
End If

thats it

Its due to a conflict.

Clear all keys from ssh-agent

ssh-add -d ~/.ssh/id_rsa
ssh-add -d ~/.ssh/github

Add the github ssh key

ssh-add   ~/.ssh/github

It should work now.

Just adding for easy implementation. You can simply make a form and then make the submit button hidden:

For example:

<form action="submit.php" method="post">
Name : <input type="text" name="test">
<input type="submit" style="display: none;">
</form>

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

The condition should be,

if number == 10000 and number <= 30000:
     print("5% tax payable")

reason for using number == 10000 is that if number's value is 50000 and if we use number >= 10000 the condition will pass, which is not what you want.

select * from table where name regexp '^word[1-3]$'

For equals, look into Secrets of Equals by Angelika Langer. I love it very much. She's also a great FAQ about Generics in Java. View her other articles here (scroll down to "Core Java"), where she also goes on with Part-2 and "mixed type comparison". Have fun reading them!

You have the alias inside of the case, it needs to be outside of the END:

Insert into TblStuff (FullName,Address,City,Zip)
Select
  Case
    When Middle is Null 
    Then Fname + LName
    Else Fname +' ' + Middle + ' '+ Lname
  End as FullName,
  Case
    When Address2 is Null Then Address1
    else Address1 +', ' + Address2 
  End as  Address,
  City as City,
  Zip as Zip
from tblImport

In Notepad++ you can select few lines and use CTRL+Q which will automaticaly make block comments for selected lines.

Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms.

In the Java context, we first need to make a distinction between "copying a value" and "copying an object".

int a = 1;
int b = a;     // copying a value
int[] s = new int[]{42};
int[] t = s;   // copying a value (the object reference for the array above)

StringBuffer sb = new StringBuffer("Hi mom");
               // copying an object.
StringBuffer sb2 = new StringBuffer(sb);

In short, an assignment of a reference to a variable whose type is a reference type is "copying a value" where the value is the object reference. To copy an object, something needs to use new, either explicitly or under the hood.

Now for "shallow" versus "deep" copying of objects. Shallow copying generally means copying only one level of an object, while deep copying generally means copying more than one level. The problem is in deciding what we mean by a level. Consider this:

public class Example {
    public int foo;
    public int[] bar;
    public Example() { };
    public Example(int foo, int[] bar) { this.foo = foo; this.bar = bar; };
}

Example eg1 = new Example(1, new int[]{1, 2});
Example eg2 = ... 

The normal interpretation is that a "shallow" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to the same array as in the original; e.g.

Example eg2 = new Example(eg1.foo, eg1.bar);

The normal interpretation of a "deep" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to a copy of the original array; e.g.

Example eg2 = new Example(eg1.foo, Arrays.copy(eg1.bar));

(People coming from a C / C++ background might say that a reference assignment produces a shallow copy. However, that's not what we normally mean by shallow copying in the Java context ...)

Two more questions / areas of uncertainty exist:

• How deep is deep? Does it stop at two levels? Three levels? Does it mean the whole graph of connected objects?

• What about encapsulated data types; e.g. a String? A String is actually not just one object. In fact, it is an "object" with some scalar fields, and a reference to an array of characters. However, the array of characters is completely hidden by the API. So, when we talk about copying a String, does it make sense to call it a "shallow" copy or a "deep" copy? Or should we just call it a copy?

Finally, clone. Clone is a method that exists on all classes (and arrays) that is generally thought to produce a copy of the target object. However:

• The specification of this method deliberately does not say whether this is a shallow or deep copy (assuming that is a meaningful distinction).

• In fact, the specification does not even specifically state that clone produces a new object.

Here's what the javadoc says:

"Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression x.clone() != x will be true, and that the expression x.clone().getClass() == x.getClass() will be true, but these are not absolute requirements. While it is typically the case that x.clone().equals(x) will be true, this is not an absolute requirement."

Note, that this is saying that at one extreme the clone might be the target object, and at the other extreme the clone might not equal the original. And this assumes that clone is even supported.

In short, clone potentially means something different for every Java class.

Some people argue (as @supercat does in comments) that the Java clone() method is broken. But I think the correct conclusion is that the concept of clone is broken in the context of OO. AFAIK, it is impossible to develop a unified model of cloning that is consistent and usable across all object types.

Getting the Phone Number, IMEI, and SIM Card ID

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

For SIM card, use the getSimSerialNumber()

    //---get the SIM card ID---
    String simID = tm.getSimSerialNumber();
    if (simID != null)
        Toast.makeText(this, "SIM card ID: " + simID, 
        Toast.LENGTH_LONG).show();

Phone number of your phone, use the getLine1Number() (some device's dont return the phone number)

    //---get the phone number---
    String telNumber = tm.getLine1Number();
    if (telNumber != null)        
        Toast.makeText(this, "Phone number: " + telNumber, 
        Toast.LENGTH_LONG).show();

IMEI number of the phone, use the getDeviceId()

    //---get the IMEI number---
    String IMEI = tm.getDeviceId();
    if (IMEI != null)        
        Toast.makeText(this, "IMEI number: " + IMEI, 
        Toast.LENGTH_LONG).show();

The .ToLowerCase version is not going to be faster - it involves an extra string allocation (which must later be collected), etc.

Personally, I'd use

string.Equals(val, "astringvalue",  StringComparison.OrdinalIgnoreCase)

this avoids all the issues of culture-sensitive strings, but as a consequence it avoids all the issues of culture-sensitive strings. Only you know whether that is OK in your context.

Using the string.Equals static method avoids any issues with val being null.

This is what worked for me.

You can use a CASE statement with an aggregate function. This is basically the same thing as a PIVOT function in some RDBMS:

SELECT distributor_id,
    count(*) AS total,
    sum(case when level = 'exec' then 1 else 0 end) AS ExecCount,
    sum(case when level = 'personal' then 1 else 0 end) AS PersonalCount
FROM yourtable
GROUP BY distributor_id

Ideally you should try not to modify the internal data representation for the purpose of creating the table. Whats the problem with String.format()? It will return you new string with required width.

UPDATE: This answer was originally written in 2008 when nth-of-type support was unreliable at best. Today I'd say you could safely use something like .bar:nth-of-type(2), unless you have to support IE8 and older.

Original answer from 2008 follows (Note that I would not recommend this anymore!):

If you can use Prototype JS you can use this code to set some style values, or add another classname:

// set style:
$$('div.theclassname')[1].setStyle({ backgroundColor: '#900', fontSize: '1.2em' });
// OR add class name:
$$('div.theclassname')[1].addClassName('secondclass'); // pun intentded...

(I didn't test this code, and it doesn't check if there actually is a second div present, but something like this should work.)

But if you're generating the html serverside you might just as well add an extra class on the second item...

It is a basic law that Strings in java are immutable and case sensitive.

To calculate MD5 hash of CLOB content field with my desired encoding without implicitly recoding content to AL32UTF8, I've used this code:

create or replace function clob2blob(AClob CLOB) return BLOB is
  Result BLOB;
  o1 integer;
  o2 integer;
  c integer;
  w integer;
begin
  o1 := 1;
  o2 := 1;
  c := 0;
  w := 0;
  DBMS_LOB.CreateTemporary(Result, true);
  DBMS_LOB.ConvertToBlob(Result, AClob, length(AClob), o1, o2, 0, c, w);
  return(Result);
end clob2blob;
/

update my_table t set t.hash = (rawtohex(DBMS_CRYPTO.Hash(clob2blob(t.content),2)));

As of Xcode 8 Objective-C now supports class properties:

@interface MyClass : NSObject
@property (class, nonatomic, assign, readonly) NSUUID* identifier;
@end

Since class properties are never synthesised you need to write your own implementation.

@implementation MyClass
static NSUUID*_identifier = nil;

+ (NSUUID *)identifier {
  if (_identifier == nil) {
    _identifier = [[NSUUID alloc] init];
  }
  return _identifier;
}
@end

You access the class properties using normal dot syntax on the class name:

MyClass.identifier;

Set your button in normal way and use event.preventDefault like..

   <button onclick="myFunc(e)"> Remove </button>  
   ...
   ...

   In function...

   function myFunc(e){
       e.preventDefault();
   }

You could use hidden input tags. I get no validation errors at w3.org with this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html lang='en' xml:lang='en' xmlns='http://www.w3.org/1999/xhtml'>
  <head>
    <meta content="text/html;charset=UTF-8" http-equiv="content-type" />
    <title>Hello</title>
  </head>
  <body>
    <div>
      <a class="article" href="link/for/non-js-users.html">
        <input style="display: none" name="articleid" type="hidden" value="5" />
      </a>
    </div>
  </body>
</html>

With jQuery you'd get the article ID with something like (not tested):

$('.article input[name=articleid]').val();

But I'd recommend HTML5 if that is an option.

To expand on the answer I came here to get a better understanding so I wrote this that can explain it and helped me too.

It has the setlocal DisableDelayedExpansion in there so you can locally set this as you wish between the setlocal EnableDelayedExpansion and it.

@echo off
title %~nx0
for /f "tokens=*" %%A in ("Some Thing") do (
  setlocal EnableDelayedExpansion
  set z=%%A
  echo !z!        Echoing the assigned variable in setlocal scope.
  echo %%A        Echoing the variable in local scope.
  setlocal DisableDelayedExpansion
  echo !z!        &rem !z!           Neither of these now work, which makes sense.
  echo %z%        &rem ECHO is off.  Neither of these now work, which makes sense.
  echo %%A        Echoing the variable in its local scope, will always work.
  )

I also faced the same issue with Eclipse when I ran the clean build with Maven, but there is a simple solution for this issue. We just need to run Maven update and then build or direct run the application. I hope it will solve the problem.

CSV Files with Custom Delimiters

By default, a comma is used as a delimiter in a CSV file. However, some CSV files can use delimiters other than a comma. Few popular ones are | and \t.

import csv
data_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter='|')
    writer.writerows(data_list)

output:

SN|Name|Contribution
1|Linus Torvalds|Linux Kernel
2|Tim Berners-Lee|World Wide Web
3|Guido van Rossum|Python Programming

Write CSV files with quotes

             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC, delimiter=';')
    writer.writerows(row_list) 

output:

"SN";"Name";"Contribution"
1;"Linus Torvalds";"Linux Kernel"
2;"Tim Berners-Lee";"World Wide Web"
3;"Guido van Rossum";"Python Programming"

As you can see, we have passed csv.QUOTE_NONNUMERIC to the quoting parameter. It is a constant defined by the csv module.

csv.QUOTE_NONNUMERIC specifies the writer object that quotes should be added around the non-numeric entries.

There are 3 other predefined constants you can pass to the quoting parameter:

• csv.QUOTE_ALL - Specifies the writer object to write CSV file with quotes around all the entries.
• csv.QUOTE_MINIMAL - Specifies the writer object to only quote those fields which contain special characters (delimiter, quotechar or any characters in lineterminator)
• csv.QUOTE_NONE - Specifies the writer object that none of the entries should be quoted. It is the default value.

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC,
                        delimiter=';', quotechar='*')
    writer.writerows(row_list)

output:

*SN*;*Name*;*Contribution*
1;*Linus Torvalds*;*Linux Kernel*
2;*Tim Berners-Lee*;*World Wide Web*
3;*Guido van Rossum*;*Python Programming*

Here, we can see that quotechar='*' parameter instructs the writer object to use * as quote for all non-numeric values.

Are we talking about standard java.io.FileReader? Won't work, but it's not hard without it.

/src/main/resources maven directory contents are placed in the root of your CLASSPATH, so you can simply retrieve it using:

InputStream is = getClass().getResourceAsStream("/storedProcedures.sql");

If the result is not null (resource not found), feel free to wrap it in a reader:

Reader reader = new InputStreamReader(is);

You need to add to your PYTHONPATH variable instead of Windows PATH variable.

http://docs.python.org/using/windows.html

One of these should work:

import math
math.trunc(1.5)
> 1
math.trunc(-1.5)
> -1
math.floor(1.5)
> 1
math.floor(-1.5)
> -2

The other way around, if you have problems ADDING the lines to your panel dont forget to add the to your TABLE. By default (http://getbootstrap.com/components/#panels), it is suppose to add the line but It helped me to add the tag so now the row lines are shown.

The following example "probably" wont display the lines between rows:

<div class="panel panel-default">
    <!-- Default panel contents -->
    <div class="panel-heading">Panel heading</div>
    <!-- Table -->
    <table class="table">
        <tr><td> Hi 1! </td></tr>
        <tr><td> Hi 2! </td></tr>
    </table>
</div>

The following example WILL display the lines between rows:

<div class="panel panel-default">
    <!-- Default panel contents -->
    <div class="panel-heading">Panel heading</div>
    <!-- Table -->
    <table class="table">
        <thead></thead>
        <tr><td> Hi 1! </td></tr>
        <tr><td> Hi 2! </td></tr>
    </table>
</div>

The same way you declare any other variable, just use the bit type:

DECLARE @MyVar bit
Set @MyVar = 1  /* True */
Set @MyVar = 0  /* False */

SELECT * FROM [MyTable] WHERE MyBitColumn = @MyVar

This is a bit old, but I came here because I had the same issue. I'm using JUnit but this time in a Kotlin app with mockk. I'm posting a sample here for reference and comparison with the Java counterpart:

@Test
fun demo() {
  // mock a sample function
  val aMock: (String) -> (String) = mockk()

  // make it return the same as the argument on every invocation
  every {
    aMock.invoke(any())
  } answers {
    firstArg()
  }

  // test it
  assertEquals("senko", aMock.invoke("senko"))
  assertEquals("senko1", aMock.invoke("senko1"))
  assertNotEquals("not a senko", aMock.invoke("senko"))
}

If you recently reached here as I did when searching for the same error in vain you may find it to be an update to NSS causing failure on CentOS. Test by running yum update and see if you get errors, curl also creates this error. Solution is simple enough just install NSS manually.

Read on...

If you're like me it threw up an error similar to this:

curl: (77) Problem with the SSL CA cert (path? access rights?)

This took some time to solve but found that it wasn't the CA cert because by recreating them and checking all the configuration I had ruled it out. It could have been libcurl so I went in search of updates.

As mentioned I recreated CA certs. You can do this also but it may be a waste of time. http://wiki.centos.org/HowTos/Https

The next step (probably should of been my first) was to check that everything was up-to-date by simply running yum.

$ yum update
$ yum upgrade

This gave me an affirmative answer that there was a bigger problem at play: Downloading Packages: error: rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: BAD Problem opening package nss-softokn-freebl-3.14.3–19.el6_6.x86_64.rpm I started reading about Certificate Verification with NSS and how this new update may be related to my problems. So yum is broken. This is because nss-softokn-* needs nss-softokn-freebl-* need each other to function. The problem is they don't check each others version for compatibility and in some cases it ends up breaking yum. Lets go fix things:

$ wget http://mirrors.linode.com/centos/6.6/updates/x86_64/Packages/nsssoftokn-freebl-3.14.3-19.el6_6.x86_64.rpm
$ rpm -Uvh nss-softokn-freebl-3.14.3–19.el6_6.x86_64.rpm
$ yum update

You should of course download from your nearest mirror and check for the correct version / OS etc. We basically download and install the update from the rpm to fix yum. As @grumpysysadmin pointed out you can shorten the commands down. @cwgtex contributed that you should install the upgrade using the RPM command making the process even simplier.

To fix things with wordpress you need to restart your http server.

$ service httpd restart

Try again and success!

It depends on your purpose. If you program for the Web, avoid indexOf, it isn't supported by Internet Explorer 6 (lot of them still used!), or do conditional use:

if (yourArray.indexOf !== undefined) result = yourArray.indexOf(target);
else result = customSlowerSearch(yourArray, target);

indexOf is probably coded in native code, so it is faster than anything you can do in JavaScript (except binary search/dichotomy if the array is appropriate). Note: it is a question of taste, but I would do a return false; at the end of your routine, to return a true Boolean...

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

I also put an answer there, but the article @Colonel Panic's update refers to suggests forcing TLS 1.2. In the future, when TLS 1.2 is compromised or just superceded, having your code stuck to TLS 1.2 will be considered a deficiency. Negotiation to TLS1.2 is enabled in .Net 4.6 by default. If you have the option to upgrade your source to .Net 4.6, I would highly recommend that change over forcing TLS 1.2.

If you do force TLS 1.2, strongly consider leaving some type of breadcrumb that will remove that force if you do upgrade to the 4.6 or higher framework.

In recent browsers you can use:

Object.keys(obj.Data).length

See MDN

For older browsers, use the for-in loop in Michael Geary's answer.

The Easy Way™

It turns out that this is such a common and useful practice that the overlords of Git made it really easy, but you have to have a newer version of Git (>= 1.7.11 May 2012). See the appendix for how to install the latest Git. Also, there's a real-world example in the walkthrough below.

0. Prepare the old repo

    cd <big-repo>
    git subtree split -P <name-of-folder> -b <name-of-new-branch>
   

Note: <name-of-folder> must NOT contain leading or trailing characters. For instance, the folder named subproject MUST be passed as subproject, NOT ./subproject/

Note for Windows users: When your folder depth is > 1, <name-of-folder> must have *nix style folder separator (/). For instance, the folder named path1\path2\subproject MUST be passed as path1/path2/subproject

1. Create the new repo

    mkdir ~/<new-repo> && cd ~/<new-repo>
    git init
    git pull </path/to/big-repo> <name-of-new-branch>
   

2. Link the new repo to GitHub or wherever

    git remote add origin <[email protected]:user/new-repo.git>
    git push -u origin master
   

3. Cleanup inside <big-repo>, if desired

    git rm -rf <name-of-folder>
   

Note: This leaves all the historical references in the repository. See the Appendix below if you're actually concerned about having committed a password or you need to decreasing the file size of your .git folder.

Walkthrough

These are the same steps as above, but following my exact steps for my repository instead of using <meta-named-things>.

Here's a project I have for implementing JavaScript browser modules in node:

tree ~/node-browser-compat

node-browser-compat
+-- ArrayBuffer
+-- Audio
+-- Blob
+-- FormData
+-- atob
+-- btoa
+-- location
+-- navigator

I want to split out a single folder, btoa, into a separate Git repository

cd ~/node-browser-compat/
git subtree split -P btoa -b btoa-only

I now have a new branch, btoa-only, that only has commits for btoa and I want to create a new repository.

mkdir ~/btoa/ && cd ~/btoa/
git init
git pull ~/node-browser-compat btoa-only

Next, I create a new repo on GitHub or Bitbucket, or whatever and add it as the origin

git remote add origin [email protected]:node-browser-compat/btoa.git
git push -u origin master

Happy day!

Note: If you created a repo with a README.md, .gitignore and LICENSE, you will need to pull first:

git pull origin master
git push origin master

Lastly, I'll want to remove the folder from the bigger repo

git rm -rf btoa

Appendix

Latest Git on macOS

To get the latest version of Git using Homebrew:

brew install git

Latest Git on Ubuntu

sudo apt-get update
sudo apt-get install git
git --version

If that doesn't work (you have a very old version of Ubuntu), try

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git

If that still doesn't work, try

sudo chmod +x /usr/share/doc/git/contrib/subtree/git-subtree.sh
sudo ln -s \
/usr/share/doc/git/contrib/subtree/git-subtree.sh \
/usr/lib/git-core/git-subtree

Thanks to rui.araujo from the comments.

Clearing your history

By default removing files from Git doesn't actually remove them, it just commits that they aren't there anymore. If you want to actually remove the historical references (i.e. you committed a password), you need to do this:

git filter-branch --prune-empty --tree-filter 'rm -rf <name-of-folder>' HEAD

After that, you can check that your file or folder no longer shows up in the Git history at all

git log -- <name-of-folder> # should show nothing

However, you can't "push" deletes to GitHub and the like. If you try, you'll get an error and you'll have to git pull before you can git push - and then you're back to having everything in your history.

So if you want to delete history from the "origin" - meaning to delete it from GitHub, Bitbucket, etc - you'll need to delete the repo and re-push a pruned copy of the repo. But wait - there's more! - if you're really concerned about getting rid of a password or something like that you'll need to prune the backup (see below).

Making .git smaller

The aforementioned delete history command still leaves behind a bunch of backup files - because Git is all too kind in helping you to not ruin your repo by accident. It will eventually delete orphaned files over the days and months, but it leaves them there for a while in case you realize that you accidentally deleted something you didn't want to.

So if you really want to empty the trash to reduce the clone size of a repo immediately you have to do all of this really weird stuff:

rm -rf .git/refs/original/ && \
git reflog expire --all && \
git gc --aggressive --prune=now

git reflog expire --all --expire-unreachable=0
git repack -A -d
git prune

That said, I'd recommend not performing these steps unless you know that you need to - just in case you did prune the wrong subdirectory, y'know? The backup files shouldn't get cloned when you push the repo, they'll just be in your local copy.

I am posting this answer because none of the other answers given here actually worked for me. I could not use COPY from within Postgres, because I did not have the correct permissions. So I chose "Export grid rows" and saved the output as UTF-8.

The psql version given by @Brian also did not work for me, for a different reason. The reason it did not work is that apparently the Windows command prompt (I was using Windows) was meddling around with the encoding on its own. I kept getting this error:

ERROR: character with byte sequence 0x81 in encoding "WIN1252" has no equivalent in encoding "UTF8"

The solution I ended up using was to write a short JDBC script (Java) which read the CSV file and issued insert statements directly into my Postgres table. This worked, but the command prompt also would have worked had it not been altering the encoding.

From page 106 of the ggplot2 book by Hadley Wickham:

The default colour scheme, scale_colour_hue picks evenly spaced hues around the hcl colour wheel.

With a bit of reverse engineering you can construct this function:

ggplotColours <- function(n = 6, h = c(0, 360) + 15){
  if ((diff(h) %% 360) < 1) h[2] <- h[2] - 360/n
  hcl(h = (seq(h[1], h[2], length = n)), c = 100, l = 65)
}

Demonstrating this in barplot:

y <- 1:3
barplot(y, col = ggplotColours(n = 3))

while condition is True: 
  stuff()
else:
  stuff()

import {Component,ViewChild} from '@angular/core' /*Import View Child*/

@Component({
    selector:'display'
    template:`

     <input #myname (input) = "updateName(myname.value)"/>
     <p> My name : {{myName}}</p>

    `
})
export class DisplayComponent{
  @ViewChild('myname')inputTxt:ElementRef; /*create a view child*/

   myName: string;

    updateName: Function;
    constructor(){

        this.myName = "Aman";
        this.updateName = function(input: String){

            this.inputTxt.nativeElement.value=this.myName; 

            /*assign to it the value*/
        };
    }
}

I found a way to do it without replacing the slashes

select CONVERT(VARCHAR(10), GETDATE(), 112)

This would return: "YYYYMMDD"

Here is a technique I use that has worked well:

<div>_x000D_
    <div style="display: table-cell; width: 100%">&nbsp;</div>_x000D_
    <div style="display: table-cell; white-space: nowrap;">Something Here</div>_x000D_
</div>

I know this is not fully relevant, but since this answer is ranked first many a times when you search 'how to display images in Jupyter', please consider this answer as well.

You could use matplotlib to show an image as follows.

import matplotlib.image as mpimg
image = mpimg.imread("your_image.png")
plt.imshow(image)
plt.show()

Download codeblocks-13.12mingw-setup.exe instead of codeblocks-13.12setup.exe from the official site. Here 13.12 is the latest version so far.

That's a half-open interval.

• A closed interval [a,b] includes the end points.
• An open interval (a,b) excludes them.

In your case the end-point at the start of the interval is included, but the end is excluded. So it means the interval "first1 <= x < last1".

Half-open intervals are useful in programming because they correspond to the common idiom for looping:

for (int i = 0; i < n; ++i) { ... } 

Here i is in the range [0, n).

I hope this answers the intent of the question. Although there are no Booleans in SQL Server, if you have a database that had Boolean types that was translated from Access, the phrase which works in Access was "...WHERE Foo" (Foo is the Boolean column name). It can be replaced by "...WHERE Foo<>0" ... and this works. Good luck!

I have created a filter. The filter can be used in any page.

Vue.filter('toCurrency', function (value) {
    if (typeof value !== "number") {
        return value;
    }
    var formatter = new Intl.NumberFormat('en-US', {
        style: 'currency',
        currency: 'USD',
        minimumFractionDigits: 0
    });
    return formatter.format(value);
});

Then I can use this filter like this:

        <td class="text-right">
            {{ invoice.fees | toCurrency }}
        </td>

I used these related answers to help with the implementation of the filter:

• How to format numbers as currency string?
• Check whether variable is number or string in JavaScript

If using Newtonsoft.Json:

using Newtonsoft.Json;
using System.Net.Http;
using System.Text;

public static class Extensions
{
    public static StringContent AsJson(this object o)
        => new StringContent(JsonConvert.SerializeObject(o), Encoding.UTF8, "application/json");
}

Example:

var httpClient = new HttpClient();
var url = "https://www.duolingo.com/2016-04-13/login?fields=";
var data = new { identifier = "username", password = "password" };
var result = await httpClient.PostAsync(url, data.AsJson())

This is a stab in the dark, but maybe do you need to wrap your JSON arguments; like say something like this:

data: "{'Ids':[{'Id1':'2'},{'Id2':'2'}]}"

Make sure your JSON is properly formed?

Maybe you should use a display inline-block too:

.circle {
    display: inline-block;
    height: 25px;
    width: 25px;
    background-color: #bbb;
    border-radius: 50%;
    z-index: -1;
}

If you are installing into local repository, there is no special index/cache update needed.

Make sure that:

1. You have installed the first artifact in your local repository properly. Simply copying the file to .m2 may not work as expected. Make sure you install it by mvn install

2. The dependency in 2nd project is setup correctly. Check on any typo in groupId/artifactId/version, or unmatched artifact type/classifier.

If you just want to select the used range, use

ActiveSheet.UsedRange.Select

If you want to select from A1 to the end of the used range, you can use the SpecialCells method like this

With ActiveSheet
    .Range(.Cells(1, 1), .Cells.SpecialCells(xlCellTypeLastCell)).Select
End With

Sometimes Excel gets confused on what is the last cell. It's never a smaller range than the actual used range, but it can be bigger if some cells were deleted. To avoid that, you can use Find and the asterisk wildcard to find the real last cell.

Dim rLastCell As Range

With Sheet1
    Set rLastCell = .Cells.Find("*", .Cells(1, 1), xlValues, xlPart, , xlPrevious)

    .Range(.Cells(1, 1), rLastCell).Select
End With

Finally, make sure you're only selecting if you really need to. Most of what you need to do in Excel VBA you can do directly to the Range rather than selecting it first. Instead of

.Range(.Cells(1, 1), rLastCell).Select
Selection.Font.Bold = True

You can

.Range(.Cells(1,1), rLastCells).Font.Bold = True

The other answers are generally correct and all outdated. Do use java.time, the modern Java date and time API, for your date and time work. With java.time your job has also become a lot easier compared to the situation when this question was asked in February 2014.

    String dateTimeString = "2014-01-16T10:25:00";
    LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
    LocalDateTime now = LocalDateTime.now(ZoneId.systemDefault());

    if (dateTime.isBefore(now)) {
        System.out.println(dateTimeString + " is in the past");
    } else if (dateTime.isAfter(now)) {
        System.out.println(dateTimeString + " is in the future");
    } else {
        System.out.println(dateTimeString + " is now");
    }

When running in 2020 output from this snippet is:

2014-01-16T10:25:00 is in the past

Since your string doesn’t inform of us any time zone or UTC offset, we need to know what was understood. The code above uses the device’ time zone setting. For a known time zone use like for example ZoneId.of("Asia/Ulaanbaatar"). For UTC specify ZoneOffset.UTC.

I am exploiting the fact that your string is in ISO 8601 format. The classes of java.time parse the most common ISO 8601 variants without us having to give any formatter.

Question: For Android development doesn’t java.time require Android API level 26?

java.time works nicely on both older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In non-Android Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

I don't think there is anything built-in, but you can do it by leaving more space above your axes and using figtext:

axes([.1,.1,.8,.7])
figtext(.5,.9,'Foo Bar', fontsize=18, ha='center')
figtext(.5,.85,'Lorem ipsum dolor sit amet, consectetur adipiscing elit',fontsize=10,ha='center')

ha is short for horizontalalignment.

In the accepted answer you get annoying spacing between the visible rows when the expandable row is hidden. You can get rid of that by adding this to css:

.collapse-row.collapsed + tr {
     display: none;
}

'+' is adjacent sibling selector, so if you want your expandable row to be the next row, this selects the next tr following tr named collapse-row.

Here is updated fiddle: http://jsfiddle.net/Nb7wy/2372/

Just use this : Make sure using nibName otherwise preloaded views of xib will not show :

var vc : ViewController = ViewController(nibName: "ViewController", bundle: nil) //change this to your class name

 self.presentViewController(vc, animated: true, completion: nil)

When you do your #includes in main.c, put the #include reference to the file that contains the referenced function at the top of the include list. e.g. Say this is main.c and your referenced function is in "SSD1306_LCD.h"

#include "SSD1306_LCD.h"    
#include "system.h"        #include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <string.h>
#include <math.h>
#include <libpic30.h>       // http://microchip.wikidot.com/faq:74
#include <stdint.h>
#include <stdbool.h>
#include "GenericTypeDefs.h"  // This has the 'BYTE' type definition

The above will not generate the "implicit declaration of function" error, but below will-

#include "system.h"        
#include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <string.h>
#include <math.h>
#include <libpic30.h>       // http://microchip.wikidot.com/faq:74
#include <stdint.h>
#include <stdbool.h>
#include "GenericTypeDefs.h"     // This has the 'BYTE' type definition
#include "SSD1306_LCD.h"    

Exactly the same #include list, just different order.

Well, it did for me.

There's no magical solution of displaying something outside an overflow hidden container.

A similar effect can be achieved by having an absolute positioned div that matches the size of its parent by positioning it inside your current relative container (the div you don't wish to clip should be outside this div):

#1 .mask {
  width: 100%;
  height: 100%;
  position: absolute;
  z-index: 1;
  overflow: hidden;
}

Take in mind that if you only have to clip content on the x axis (which appears to be your case, as you only have set the div's width), you can use overflow-x: hidden.

in (backend.php) be sure to include include

I believe this answer is cleaner, (based on https://stackoverflow.com/a/3007668/550975)

    public ActionResult GetAttachment(long id)
    {
        FileAttachment attachment;
        using (var db = new TheContext())
        {
            attachment = db.FileAttachments.FirstOrDefault(x => x.Id == id);
        }

        return File(attachment.FileData, "application/force-download", Path.GetFileName(attachment.FileName));
    }

For me, when typing the url, a user accidentally used a / instead of a ? to start the query parameters

e.g.:

url.com/endpoint/parameter=SomeValue&otherparameter=Another+value

which should have been:

url.com/endpoint?parameter=SomeValue&otherparameter=Another+value

Your question almost spells the SQL for this:

DELETE FROM table WHERE id IN (1, 4, 6, 7)

From the Package Manager console window, often whatever command you used to install a package can be used to uninstall that package. Simply replace the INSTALL command with UNINSTALL.

For example, to install PowerTCPTelnet, the command is:

Install-Package PowerTCPTelnet -Version 4.4.9

To uninstall same, the command is:

Uninstall-Package PowerTCPTelnet -Version 4.4.9

1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.

2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):

This rule will do SINGLE EXACT rewrite (internal redirect) /page to /page.html. URL in browser will remain unchanged.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRewrite" stopProcessing="true">
                <match url="^page$" />
                <action type="Rewrite" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page it will check if /page.html exists, and if it does then rewrite occurs):

<system.webServer>
    <rewrite>
        <rules>
            <rule name="DynamicRewrite" stopProcessing="true">
                <match url="(.*)" />
                <conditions>
                    <add input="{REQUEST_FILENAME}\.html" matchType="IsFile" />
                </conditions>
                <action type="Rewrite" url="/{R:1}.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

here is my solution:

$(el).on('touchstart', function(e) {
    var link = $(e.target.parentNode).closest('a')  
    if(link.length > 0) {
        window.location.href = link.attr('href');
    }
});

If you have a javax.net.ssl.SSLSocket class reference in your code, you can set the enabled TLS protocols by a call to SSLSocket.setEnabledProtocols():

import javax.net.ssl.*;
import java.net.*; 
...
Socket socket = SSLSocketFactory.getDefault().createSocket();
...
if (socket instanceof SSLSocket) {
   // "TLSv1.0" gives IllegalArgumentException in Java 8
   String[] protos = {"TLSv1.2", "TLSv1.1"}
   ((SSLSocket)socket).setEnabledProtocols(protos);
}

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

Using foreach loop without key

foreach($array as $item) {
    echo $item['filename'];
    echo $item['filepath'];

    // to know what's in $item
    echo '<pre>'; var_dump($item);
}

Using foreach loop with key

foreach($array as $i => $item) {
    echo $item[$i]['filename'];
    echo $item[$i]['filepath'];

    // $array[$i] is same as $item
}

Using for loop

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

var_dump is a really useful function to get a snapshot of an array or object.

From https://idlebox.net/2010/apidocs/gdb-7.0.zip/gdb_9.html

The values of arguments that were not saved in their stack frames are shown as `value optimized out'.

Im guessing you compiled with -O(somevalue) and are accessing variables a,b,c in a function where optimization has occurred.

Another way to escape quotes (though probably not preferable), which I've found used in certain places is to use multiple double-quotes. For the purpose of making other people's code legible, I'll explain.

Here's a set of basic rules:

1. When not wrapped in double-quoted groups, spaces separate parameters:
   program param1 param2 param 3 will pass four parameters to program.exe:
        param1, param2, param, and 3.
2. A double-quoted group ignores spaces as value separators when passing parameters to programs:
   program one two "three and more" will pass three parameters to program.exe:
        one, two, and three and more.
Now to explain some of the confusion:
3. Double-quoted groups that appear directly adjacent to text not wrapped with double-quotes join into one parameter:
   hello"to the entire"world acts as one parameter: helloto the entireworld.
Note: The previous rule does NOT imply that two double-quoted groups can appear directly adjacent to one another.
4. Any double-quote directly following a closing quote is treated as (or as part of) plain unwrapped text that is adjacent to the double-quoted group, but only one double-quote:
   "Tim says, ""Hi!""" will act as one parameter: Tim says, "Hi!"

Thus there are three different types of double-quotes: quotes that open, quotes that close, and quotes that act as plain-text.
Here's the breakdown of that last confusing line:

"   open double-quote group
T   inside ""s
i   inside ""s
m   inside ""s
    inside ""s - space doesn't separate
s   inside ""s
a   inside ""s
y   inside ""s
s   inside ""s
,   inside ""s
    inside ""s - space doesn't separate
"   close double-quoted group
"   quote directly follows closer - acts as plain unwrapped text: "
H   outside ""s - gets joined to previous adjacent group
i   outside ""s - ...
!   outside ""s - ...
"   open double-quote group
"   close double-quote group
"   quote directly follows closer - acts as plain unwrapped text: "

Thus, the text effectively joins four groups of characters (one with nothing, however):
Tim says,  is the first, wrapped to escape the spaces
"Hi! is the second, not wrapped (there are no spaces)
 is the third, a double-quote group wrapping nothing
" is the fourth, the unwrapped close quote.

As you can see, the double-quote group wrapping nothing is still necessary since, without it, the following double-quote would open up a double-quoted group instead of acting as plain-text.

From this, it should be recognizable that therefore, inside and outside quotes, three double-quotes act as a plain-text unescaped double-quote:

"Tim said to him, """What's been happening lately?""""

will print Tim said to him, "What's been happening lately?" as expected. Therefore, three quotes can always be reliably used as an escape.
However, in understanding it, you may note that the four quotes at the end can be reduced to a mere two since it technically is adding another unnecessary empty double-quoted group.

Here are a few examples to close it off:

program a b                       REM sends (a) and (b)
program """a"""                   REM sends ("a")
program """a b"""                 REM sends ("a) and (b")
program """"Hello,""" Mike said." REM sends ("Hello," Mike said.)
program ""a""b""c""d""            REM sends (abcd) since the "" groups wrap nothing
program "hello to """quotes""     REM sends (hello to "quotes")
program """"hello world""         REM sends ("hello world")
program """hello" world""         REM sends ("hello world")
program """hello "world""         REM sends ("hello) and (world")
program "hello ""world"""         REM sends (hello "world")
program "hello """world""         REM sends (hello "world")

Final note: I did not read any of this from any tutorial - I came up with all of it by experimenting. Therefore, my explanation may not be true internally. Nonetheless all the examples above evaluate as given, thus validating (but not proving) my theory.

I tested this on Windows 7, 64bit using only *.exe calls with parameter passing (not *.bat, but I would suppose it works the same).
