I think the annotation you are looking for is:

public class CompanyName implements Serializable {
//...
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", insertable = false, updatable = false)
private Company company;

And you should be able to use similar mappings in a hbm.xml as shown here (in 23.4.2):

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/example-mappings.html

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

Your function is just fine but isn't working because you put the () after the last }. If you move the () to the top just next to new List<string>() the error stops.

Sample below:

List<string> optionList = new List<string>()
{
    "AdditionalCardPersonAdressType","AutomaticRaiseCreditLimit","CardDeliveryTimeWeekDay"
};

Try:

psql -U role_name -d database -h hostname..com -W

The first line moves the cursor to the last non-empty row in the column. The second line prints that columns row.

Selection.End(xlDown).Select
MsgBox(ActiveCell.Row)

There is one subtle but very important difference between == and the String.Equals methods:

class Program
{
    static void Main(string[] args)
    {
        CheckEquality("a", "a");
        Console.WriteLine("----------");
        CheckEquality("a", "ba".Substring(1));
    }

    static void CheckEquality<T>(T value1, T value2) where T : class
    {
        Console.WriteLine("value1: {0}", value1);
        Console.WriteLine("value2: {0}", value2);

        Console.WriteLine("value1 == value2:      {0}", value1 == value2);
        Console.WriteLine("value1.Equals(value2): {0}", value1.Equals(value2));

        if (typeof(T).IsEquivalentTo(typeof(string)))
        {
            string string1 = (string)(object)value1;
            string string2 = (string)(object)value2;
            Console.WriteLine("string1 == string2:    {0}", string1 == string2);
        }
    }
}

Produces this output:

value1: a
value2: a
value1 == value2:      True
value1.Equals(value2): True
string1 == string2:    True
----------
value1: a
value2: a
value1 == value2:      False
value1.Equals(value2): True
string1 == string2:    True

You can see that the == operator is returning false to two obviously equal strings. Why? Because the == operator in use in the generic method is resolved to be the op_equal method as defined by System.Object (the only guarantee of T the method has at compile time), which means that it's reference equality instead of value equality.

When you have two values typed as System.String explicitly, then == has a value-equality semantic because the compiler resolves the == to System.String.op_equal instead of System.Object.op_equal.

So to play it safe, I almost always use String.Equals instead to that I always get the value equality semantics I want.

And to avoid NullReferenceExceptions if one of the values is null, I always use the static String.Equals method:

bool true = String.Equals("a", "ba".Substring(1));

Possibly also check the sessionState tag in Web.config

Believe it or not, some projects I've worked on will set a connection string here as well.

Setting this config to:

<sessionState mode="InProc" />

Fixed this issue in my case after checking all other connection strings were correct.

'data' should be a stringified JavaScript object:

data: JSON.stringify({ "userName": userName, "password" : password })

To send your formData, pass it to stringify:

data: JSON.stringify(formData)

Some servers also require the application/json content type:

contentType: 'application/json'

There's also a more detailed answer to a similar question here: Jquery Ajax Posting json to webservice

Although answer is provided I found simpler solution:

Date:

01/20/2017

By doing replace

CurrentDate = replace(date, "/", "-")

It will output:

01-20-2017

well, the term "url encoded" is a bit vague, perhaps simple regex check will do the trick

$is_encoded = preg_match('~%[0-9A-F]{2}~i', $string);

VB.NET:

If(someBool, "true", "false")

C#

someBool ? "true" : "false";

The ISO 7000 / IEC 60417 Symbol for Pause; Interruption is #5111B. See Media_Controls

The 8086 has a large family of instructions that accept a register operand and an effective address, perform some computations to compute the offset part of that effective address, and perform some operation involving the register and the memory referred to by the computed address. It was fairly simple to have one of the instructions in that family behave as above except for skipping that actual memory operation. Thus, the instructions:

mov ax,[bx+si+5]
lea ax,[bx+si+5]

were implemented almost identically internally. The difference is a skipped step. Both instructions work something like:

temp = fetched immediate operand (5)
temp += bx
temp += si
address_out = temp  (skipped for LEA)
trigger 16-bit read  (skipped for LEA)
temp = data_in  (skipped for LEA)
ax = temp

As for why Intel thought this instruction was worth including, I'm not exactly sure, but the fact that it was cheap to implement would have been a big factor. Another factor would have been the fact that Intel's assembler allowed symbols to be defined relative to the BP register. If fnord was defined as a BP-relative symbol (e.g. BP+8), one could say:

mov ax,fnord  ; Equivalent to "mov ax,[BP+8]"

If one wanted to use something like stosw to store data to a BP-relative address, being able to say

mov ax,0 ; Data to store
mov cx,16 ; Number of words
lea di,fnord
rep movs fnord  ; Address is ignored EXCEPT to note that it's an SS-relative word ptr

was more convenient than:

mov ax,0 ; Data to store
mov cx,16 ; Number of words
mov di,bp
add di,offset fnord (i.e. 8)
rep movs fnord  ; Address is ignored EXCEPT to note that it's an SS-relative word ptr

Note that forgetting the world "offset" would cause the contents of location [BP+8], rather than the value 8, to be added to DI. Oops.

This is probably slower than what you want, but you can do:

>>> tostring = vectorize(lambda x: str(x))
>>> numpy.where(tostring(phis).astype('float64') != phis)
(array([], dtype=int64),)

It looks like it rounds off the values when it converts to str from float64, but this way you can customize the conversion however you like.

Sometimes you don't want to join multiple filters together like this:

def your_dynamic_query_generator(self, event: Event):
    qs \
    .filter(shiftregistrations__event=event) \
    .filter(shiftregistrations__shifts=False)

And the following code would actually not return the correct thing.

def your_dynamic_query_generator(self, event: Event):
    return Q(shiftregistrations__event=event) & Q(shiftregistrations__shifts=False)

What you can do now is to use an annotation count-filter.

In this case we count all shifts which belongs to a certain event.

qs: EventQuerySet = qs.annotate(
    num_shifts=Count('shiftregistrations__shifts', filter=Q(shiftregistrations__event=event))
)

Afterwards you can filter by annotation.

def your_dynamic_query_generator(self):
    return Q(num_shifts=0)

This solution is also cheaper on large querysets.

Hope this helps.

There is no need for using NSAttributedString. All you need is a simple label with the proper textColor. Plus this simple solution will work with all versions of iOS, not just iOS 6.

But if you needlessly wish to use NSAttributedString, you can do something like this:

UIColor *color = [UIColor redColor]; // select needed color
NSString *string = ... // the string to colorize
NSDictionary *attrs = @{ NSForegroundColorAttributeName : color };
NSAttributedString *attrStr = [[NSAttributedString alloc] initWithString:string attributes:attrs];
self.scanLabel.attributedText = attrStr;

You can use CSS3 RGBA in this way:

rgba(255, 0, 0, 0.7);

0.7 means 70% opacity.

give polpetta a try ...

npm install -g polpetta

then you can

and you are ready to go :-)

The answer posted above/earlier that was reported to replace CHAR(13)CHAR(10) carriage return:

REPLACE(REPLACE(REPLACE(MyField, CHAR(13) + CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(10), 'something else')

Will never get to the REPLACE(MyField, CHAR(13) + CHAR(10), 'something else') portion of the code and will return the unwanted result of:

'something else''something else'

And NOT the desired result of a single:

'something else'

That would require the REPLACE script to be rewritten as such:

REPLACE(REPLACE(REPLACE(MyField, CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(13) + CHAR(10), 'something else')

As the flow first tests the 1st/Furthest Left REPLACE statement, then upon failure will continue to test the next REPLACE statement.

base64 encode/decode example:

import base64

mystr = 'O João mordeu o cão!'

# Encode
mystr_encoded = base64.b64encode(mystr.encode('utf-8'))
# b'TyBKb8OjbyBtb3JkZXUgbyBjw6NvIQ=='

# Decode
mystr_encoded = base64.b64decode(mystr_encoded).decode('utf-8')
# 'O João mordeu o cão!'

Just to complement m59's correct answer, here is a working jsfiddle:

<body ng-app='myApp'>
    <div>
        <button my-directive>Click Me!</button>
    </div>
     <h1>{{2+3}}</h1>

</body>

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())

Velocity is a good candidate for writing this kind of stuff.
It allows you to keep your html and data-generation code as separated as possible.

Try:

Iterator<Map.Entry<String,String>> iter = testMap.entrySet().iterator();
while (iter.hasNext()) {
    Map.Entry<String,String> entry = iter.next();
    if("Sample".equalsIgnoreCase(entry.getValue())){
        iter.remove();
    }
}

With Java 1.8 and onwards you can do the above in just one line:

testMap.entrySet().removeIf(entry -> "Sample".equalsIgnoreCase(entry.getValue()));

Using current browsers you can use it like this:

img {
  -webkit-filter: grayscale(100%); /* Chrome, Safari, Opera */
  filter: grayscale(100%);
}

and to remedy it:

img:hover{
   -webkit-filter: grayscale(0%); /* Chrome, Safari, Opera */
   filter: grayscale(0%);
}

worked with me and is much shorter. There is even more one can do within the CSS:

filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() |
        hue-rotate() | invert() | opacity() | saturate() | sepia() | url();

For more information and supporting browsers see this: http://www.w3schools.com/cssref/css3_pr_filter.asp

AngularJS docs - ngController
Note that you can also attach controllers to the DOM by declaring it in a route definition via the $route service. A common mistake is to declare the controller again using ng-controller in the template itself. This will cause the controller to be attached and executed twice.

When you use ngRoute with the ng-view directive, the controller gets attached to that dom element by default (or ui-view if you use ui-router). So you will not need to attach it again in the template.

You must assign it, like this:-

df['id']= df['id'].astype(str)

Generics solution to covert any List<Type> to String []:

public static  <T> String[] listToArray(List<T> list) {
    String [] array = new String[list.size()];
    for (int i = 0; i < array.length; i++)
        array[i] = list.get(i).toString();
    return array;
}

Note You must override toString() method.

class Car {
  private String name;
  public Car(String name) {
    this.name = name;
  }
  public String toString() {
    return name;
  }
}
final List<Car> carList = new ArrayList<Car>();
carList.add(new Car("BMW"))
carList.add(new Car("Mercedes"))
carList.add(new Car("Skoda"))
final String[] carArray = listToArray(carList);

git reset --hard make changes, then do

git add -A
git commit --amend --no-edit 

git add -A
git commit --amend -m "commit_message"

git push origin master --force

--force will rewrite that commit you've reseted to in the first step.

Don't do this, because you're about to go against the whole idea of VCS systems and git in particular. The only good method is to create new and delete unneeded branch. See git help branch for info.

How about:

Random generator = new Random();
int i = 10 - generator.nextInt(10);

It checks to see whether the specific object is contained in the list.

You might be better using the Find method on the list.

Here's an example

List<CartProduct> lst = new List<CartProduct>();

CartProduct objBeer;
objBeer = lst.Find(x => (x.Name == "Beer"));

Hope that helps

You should also look at LinQ - overkill for this perhaps, but a useful tool nonetheless...

I looked everywhere for an answer and finally this worked for me:

SELECT Lower(Substring(MASTER.dbo.Fn_varbintohexstr(0x21232F297A57A5A743894A0E4A801FC3), 3, 8000))

Outputs to (string):

21232f297a57a5a743894a0e4a801fc3

You can use it in your WHERE or JOIN conditions as well in case you want to compare/match varbinary records with strings

It's better to avoid unnecessary autoboxing for 2 reasons.

For one thing, it's a bit slower than int < int, as you're (sometimes) creating an extra object;

void doSomethingWith(Integer integerObject){ ...
  int i = 1000;
  doSomethingWith(i);//gets compiled into doSomethingWith(Integer.valueOf(i));

The bigger issue is that hidden autoboxing can hide exceptions:

void doSomethingWith (Integer count){
  if (count>0)  // gets compiled into count.intValue()>0

Calling this method with null will throw a NullPointerException.

The split between primitives and wrapper objects in java was always described as a kludge for speed. Autoboxing almost hides this, but not quite - it's cleaner just to keep track of the type. So if you've got an Integer object, you can just call compare() or intValue(), and if you've got the primitive just check the value directly.

In addition to the accepted answer (https://stackoverflow.com/a/4501084/6276704):

Since Java 1.7, if you want to compare two Objects which might be null, I recommend this function:

Objects.equals(onePossibleNull, twoPossibleNull)

java.util.Objects

This class consists of static utility methods for operating on objects. These utilities include null-safe or null-tolerant methods for computing the hash code of an object, returning a string for an object, and comparing two objects.

Since: 1.7

Working on the same idea as above , but generalizing a bit . Since the backspace should work fine on the input elements , but should not work if the focus is a paragraph or something , since it is there where the page tends to go back to the previous page in history .

$('html').on('keydown' , function(event) {

        if(! $(event.target).is('input')) {
            console.log(event.which);
           //event.preventDefault();
           if(event.which == 8) {
            //  alert('backspace pressed');
            return false;
         }
        }
});

returning false => both event.preventDefault and event.stopPropagation are in effect .

Don't forget DataFrame.tail! e.g. df1.tail(10)

In a single database - yes:

USE your_database
SELECT name FROM sys.tables

Getting all tables across all databases - only with a hack.... see this SO question for several approaches how to do that: How do I list all tables in all databases in SQL Server in a single result set?

I ran to a similar error running Excel in VBA, what I've learned is that when I pull data from MSSQL, and then using get_range and .Value2 apply it's out of the range, any value that was of type uniqueidentifier (GUID) resulted in this error. Only when I cast the value to nvarcahr(max) it worked.

Yes, you can put arrays in sessions, example:

$_SESSION['name_here'] = $your_array;

Now you can use the $_SESSION['name_here'] on any page you want but make sure that you put the session_start() line before using any session functions, so you code should look something like this:

 session_start();
 $_SESSION['name_here'] = $your_array;

Possible Example:

 session_start();
 $_SESSION['name_here'] = $_POST;

Now you can get field values on any page like this:

 echo $_SESSION['name_here']['field_name'];

As for the second part of your question, the session variables remain there unless you assign different array data:

 $_SESSION['name_here'] = $your_array;

Session life time is set into php.ini file.

public static final <T> List<T> getList(final Class<T[]> clazz, final String json)
{
    final T[] jsonToObject = new Gson().fromJson(json, clazz);

    return Arrays.asList(jsonToObject);
}

Example:

getList(MyClass[].class, "[{...}]");

Here is a copy of code which works fine for me

import json

with open("test.json") as json_file:
    json_data = json.load(json_file)
    print(json_data)

with the data

{
    "a": [1,3,"asdf",true],
    "b": {
        "Hello": "world"
    }
}

you may want to wrap your json.load line with a try catch because invalid JSON will cause a stacktrace error message.

You can use List as a classifier for many fields, but you need wrap null values into Optional:

Function<String, List> classifier = (item) -> List.of(
    item.getFieldA(),
    item.getFieldB(),
    Optional.ofNullable(item.getFieldC())
);

Map<List, List<Item>> grouped = items.stream()
    .collect(Collectors.groupingBy(classifier));

Your HTML should include quotes for attributes : http://jsfiddle.net/dKWnb/4/

Not required when using a HTML5 doctype - thanks @bazmegakapa

You create the array each time and add a value to it ... its working as expected ?

Moving the array outside of the live() function works fine :

var myarray = []; // more efficient than new Array()
$("#test").live("click",function() {
        myarray.push($("#drop").val());
        alert(myarray);
});

http://jsfiddle.net/dKWnb/5/

Also note that in later versions of jQuery v1.7 -> the live() method is deprecated and replaced by the on() method.

Here's the answer to my question I got back from Apple support.

Hi XXX,

I am following up with you about the deletion of your app, “XXX”. Recent changes have been made to the App Delete feature. In order to delete your app from iTunes Connect, you must now have one approved version before the delete button becomes available. For more information on the recent changes, please see the "Deleting an App" section of the iTunes Connect Guide (page 96-97):

You can only delete an app from the App Store if it was previously approved (meaning has one approved version).

From iTunes Connect Developer Guide - Transferring and Deleting Apps:

Apps that have not been approved yet can’t be deleted; instead, reject the app.

As of 2016, new changes have been made to iTunes Connect. Here are the screenshots of deleting an approved app from your account.

Hi @Hayden Stites I faced the same issue, but after some tries I found it was happening because I was trying to create build in git bash , instead of CMD with admin access. If you create build with Command prompt run as administrator build will get create.

Another alternative is the following, although not the cleanest as it assumes the image to be the only element in a container, such as in this case:

<header class="siteHeader">
  <img src="img" class="siteLogo" />
</header>

You can then use the container as a mask with the desired size, and surround the image with a negative margin to move it into the right position:

.siteHeader{
    width: 50px;
    height: 50px;
    overflow: hidden;
}

.siteHeader .siteLogo{
    margin: -100px;
}

Demo can be seen in this JSFiddle.

Only seems to work in IE>9, and probably all significant versions of all other browsers.

I don't know when exactly the tokens expire, but they do, otherwise there wouldn't be an option to give offline permissions.

Anyway, sometimes requiring the user to give offline permissions is an overkill. Depending on your needs, maybe it's enough that the token remains valid as long as the website is opened in the user's browser. For this there may be a simpler solution - relogging the user in periodically using an iframe: facebook auto re-login from cookie php

Worked for me...

Android Cloud to Device Messaging Framework

Important: C2DM has been officially deprecated as of June 26, 2012. This means that C2DM has stopped accepting new users and quota requests. No new features will be added to C2DM. However, apps using C2DM will continue to work. Existing C2DM developers are encouraged to migrate to the new version of C2DM, called Google Cloud Messaging for Android (GCM). See the C2DM-to-GCM Migration document for more information. Developers must use GCM for new development.

Kindly check the following link:

easier & shorter via indirect: INDIRECT("'..\..\..\..\Supply\SU\SU.ods'#$Data.$A$2:$AC$200")

however indirect() has performance drawbacks if lot of links in workbook

I miss construct like: ['../Data.ods']#Sheet1.A1 in LibreOffice. The intention is here: if I create a bunch of master workbooks and depending report workbooks in limited subtree of directories in source file system, I can zip whole directory subtree with complete package of workbooks and send it to other cooperating person per Email or so. It will be saved in some other absolute pazth on target system, but linkage works again in new absolute path because it was coded relatively to subtree root.

I think the load event is right. What is not right is the way you use to retreive the content from iframe content dom.

What you need is the html of the page loaded in the iframe not the html of the iframe object.

What you have to do is to access the content document with iFrameObj.contentDocument. This returns the dom of the page loaded inside the iframe, if it is on the same domain of the current page.

I would retreive the content before removing the iframe.

I've tested in firefox and opera.

Then i think you can retreive your data with $(childDom).html() or $(childDom).find('some selector') ...

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:

• Start your intellij from terminal /Applications/IntelliJ IDEA 14.app/Contents/MacOS (this will pick your bash env variables)
• Add login env variable by executing: launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"

To directly answer your question, you can add launchctl line in your ~/.bash_profile

As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.

When using guava (See doc) there is Iterators.forEnumeration. Given an Enumeration x you can do the following:

to get a immutable Set:

ImmutableSet.copyOf(Iterators.forEnumeration(x));

to get a immutable List:

ImmutableList.copyOf(Iterators.forEnumeration(x));

to get a hashSet:

Sets.newHashSet(Iterators.forEnumeration(x));

user6779899's answer is neat and more generic However, based on the request by Imad El Hitti, a light weight solution is proposed here. This can be used when a child component is tightly connected to one parent only.

Parent.component.ts

export class Notifier {
    valueChanged: (data: number) => void = (d: number) => { };
}

export class Parent {
    notifyObj = new Notifier();
    tellChild(newValue: number) {
        this.notifyObj.valueChanged(newValue); // inform child
    }
}

Parent.component.html

<my-child-comp [notify]="notifyObj"></my-child-comp>

Child.component.ts

export class ChildComp implements OnInit{
    @Input() notify = new Notifier(); // create object to satisfy typescript
    ngOnInit(){
      this.notify.valueChanged = (d: number) => {
            console.log(`Parent has notified changes to ${d}`);
            // do something with the new value 
        };
    }
 }

I've tried using that 'UniversalBrowswerRead' thing too and it didn't work. You might be able to add an 'allow' header, but I haven't actually tried doing it yet. It's pretty new.

You can find more information here

import json
def writeToFile(logData, fileName, openOption="w"):
  file = open(fileName, openOption)
  file.write(json.dumps(json.loads(logData), indent=4)) 
  file.close()  

    public String reverse(String s) {

        String reversedString = "";
        for(int i=s.length(); i>0; i--) {
            reversedString += s.charAt(i-1);
        }   

        return reversedString;
    }

I'm not sure these are the best options but they'll definitely get the job done:

declare @durations table
(
    Duration int
)

Insert into @durations(Duration)
values(60),(80),(90),(150),(180),(1000)

--Option 1 - Manually concatenate the values together
select right('0' + convert(varchar,Duration / 60),2) + ':' + right('0' + convert(varchar,Duration % 60),2)
from @Durations

--Option 2 - Make use of the time variable available since SQL Server 2008
select left(convert(time,DATEADD(minute,Duration,0)),5)
from @durations

GO

One option if the number of keys is small is to use chained gets:

value = myDict.get('lastName', myDict.get('firstName', myDict.get('userName')))

But if you have keySet defined, this might be clearer:

value = None
for key in keySet:
    if key in myDict:
        value = myDict[key]
        break

The chained gets do not short-circuit, so all keys will be checked but only one used. If you have enough possible keys that that matters, use the for loop.

You can just type these 3 commands from command prompt:

1. start

2. start cmd

3. start cmd.exe

@SolutionYogi's answer works like a charm, but it seems that using $.each is less straightforward and efficient than directly appending listitems :

var mylist = $('#list');
var listitems = mylist.children('li').get();

listitems.sort(function(a, b) {
   return $(a).text().toUpperCase().localeCompare($(b).text().toUpperCase());
})

mylist.empty().append(listitems);

as per the Chart js documentation page tick configuration section. you can format the value of each tick using the callback function. for example I wanted to change locale of displayed dates to be always German. in the ticks parts of the axis options

ticks: {
    callback: function(value) { 
        return new Date(value).toLocaleDateString('de-DE', {month:'short', year:'numeric'}); 
    },
},

ul {
      text-align: center;
      list-style: inside;
    }

just in case someone comes with this question, this is how I do it, please forget about the repository object, I'm using the Repository Pattern, you can use your object context to retrieve the entities. And also don't pay attention to my entity names, my entity type Action has nothing to do with an MVC Action.

Controller:

ViewBag.ActionStatusId = new SelectList(repository.GetAll<ActionStatus>(), "ActionStatusId", "Name", myAction.ActionStatusId);

Pay attention that the last variable of the SelectList constructor is the selected value (object selectedValue)

Then this is my view to render it:

<div class="editor-label">
   @Html.LabelFor(model => model.ActionStatusId, "ActionStatus")
</div>
<div class="editor-field">
   @Html.DropDownList("ActionStatusId")
   @Html.ValidationMessageFor(model => model.ActionStatusId)
</div> 

I think it is pretty simple, I hope this helps! :)

Java jar files are the same format as zip files - so if you have a zip file utility that would let you modify an archive, you have your foot in the door. Second problem is, if you want to recompile a class or something, you probably will just have to re-build the jar; but a text file or something (xml, for instance) should be easily enough modified.

Try this:

String output = response.getEntity(String.class);

EDIT

Thanks to @Martin Spamer to mention that it will work for Jersey 1.x jars only. For Jersey 2.x use

String output = response.readEntity(String.class);

I believe the author was looking for an equivalent method via the IDE that would generate the code behind and make sure all parameters were in place, etc. Found this from MS:

Creating Event Handlers on the Windows Forms Designer

Coming from a VB background myself, this is what I was looking for, here is the brief version for the click adverse:

1. Click the form or control that you want to create an event handler for.
2. In the Properties window, click the Events button
3. In the list of available events, click the event that you want to create an event handler for.
4. In the box to the right of the event name, type the name of the handler and press ENTER

To list all available versions and choose from them :

sudo update-alternatives --config php

Or do manually

sudo a2dismod php7.1 // disable
sudo a2enmod php5.6  // enable

I also encountered the same issue. The best way to resolve is (for windows):

1. Go to the Task Manager.

2. Scroll and find a task process named. Node.js: Server-side JavaScript

3. End this particular task.

There you go! Now do npm start and it will work as before!

This is what worked for me...

import cv2
import numpy as np

#Created an image (really an ndarray) with three channels 
new_image = np.ndarray((3, num_rows, num_cols), dtype=int)

#Did manipulations for my project where my array values went way over 255
#Eventually returned numbers to between 0 and 255

#Converted the datatype to np.uint8
new_image = new_image.astype(np.uint8)

#Separated the channels in my new image
new_image_red, new_image_green, new_image_blue = new_image

#Stacked the channels
new_rgb = np.dstack([new_image_red, new_image_green, new_image_blue])

#Displayed the image
cv2.imshow("WindowNameHere", new_rgbrgb)
cv2.waitKey(0)

You should let the user do that if they want (and you can't stop them anyway).

Your problem is that you need to know that they have and then assume that they mean OK, not cancel. Replace confirm(x) with myConfirm(x):

function myConfirm(message) {
    var start = Number(new Date());
    var result = confirm(message);
    var end = Number(new Date());
    return (end<(start+10)||result==true);
}

While it may be completely valid HTML to not include an href, especially with an onclick handler, there are some things to consider: it will not be keyboard-focusable without having a tabindex value set. Furthermore, this will be inaccessible to screenreader software using Internet Explorer, as IE will report through the accessibility interfaces that any anchor element without an href attribute as not-focusable, regardless of whether the tabindex has been set.

So while the following may be completely valid:

<a class="arrow">Link content</a>

It's far better to explicitly add a null-effect href attribute

<a href="javascript:void(0);" class="arrow">Link content</a>

For full support of all users, if you're using the class with CSS to render an image, you should also include some text content, such as the title attribute to provide a textual description of what's going on.

<a href="javascript:void(0);" class="arrow" title="Go to linked content">Link content</a>

Other alternative, perhaps not as elegant as the use of bind, but it is valid for events in a loop

for (var key in catalog){
    document.getElementById(key).my_id = key
    document.getElementById(key).addEventListener('click', function(e) {
        editorContent.loadCatalogEntry(e.srcElement.my_id)
    }, false);
}

It has been tested for google chrome extensions and maybe e.srcElement must be replaced by e.source in other browsers

I found this solution using the comment posted by Imatoria but I cannot mark it as useful because I do not have enough reputation :D

$route: This is used for deep-linking URLs to controllers and views (HTML partials) and watches $location.url() in order to map the path from an existing definition of route.

When we use ngRoute, the route is configured with $routeProvider and when we use ui-router, the route is configured with $stateProvider and $urlRouterProvider.

<div ng-view></div>
    $routeProvider
        .when('/contact/', {
            templateUrl: 'app/views/core/contact/contact.html',
            controller: 'ContactCtrl'
        });


<div ui-view>
    <div ui-view='abc'></div>
    <div ui-view='abc'></div>
   </div>
    $stateProvider
        .state("contact", {
            url: "/contact/",
            templateUrl: '/app/Aisel/Contact/views/contact.html',
            controller: 'ContactCtrl'
        });

As far as I remember there is an xml element for the image data. You can use this website to encode a file (use the upload field). Then just copy and paste the data to the XML element.

You could also use PHP to do this like so:

 <?php
        $im = file_get_contents('filename.gif');
        $imdata = base64_encode($im);      
?> 

Use Mozilla's guide for help on creating OpenSearch plugins. For example, the icon element is used like this:

<img width="16" height="16">data:image/x-icon;base64,imageData</>

Where imageData is your base64 data.

To further work with array of maps, the followings could help:

@RequestMapping(value = "/process", method = RequestMethod.POST, headers = "Accept=application/json")
public void setLead(@RequestBody Collection<? extends Map<String, Object>> payload) throws Exception {

  List<Map<String,Object>> maps = new ArrayList<Map<String,Object>>();
  maps.addAll(payload);

}

This can also be a file that contains images or charts, see this: http://kb.tableausoftware.com/articles/knowledgebase/resolving-error-external-table-is-not-in-expected-format

The recommendation is to save as Excel 2003

== operator compares two object references to check whether they refer to same instance. This also, will return true on successful match.for example

public class Example{
public static void main(String[] args){
String s1 = "Java";
String s2 = "Java";
String s3 = new string ("Java");
test(Sl == s2)     //true
test(s1 == s3)      //false
}}

above example == is a reference comparison i.e. both objects point to the same memory location

String equals() is evaluates to the comparison of values in the objects.

   public class EqualsExample1{
   public static void main(String args[]){
   String s = "Hell";
   String s1 =new string( "Hello");
   String s2 =new string( "Hello");
   s1.equals(s2);    //true
    s.equals(s1) ;   //false
    }}

above example It compares the content of the strings. It will return true if string matches, else returns false.

var logged_in = false;
logged_in = !logged_in;

Here is some hacketi hack code. I wanted to maintain a row template in an HTML page. Table rows 0...n are rendered at request time, and this example has one hardcoded row and a simplified template row. The template table is hidden, and the row tag must be within a valid table or browsers may drop it from the DOM tree. Adding a row uses counter+1 identifier, and the current value is maintained in the data attribute. It guarantees each row gets unique URL parameters.

I have run tests on Internet Explorer 8, Internet Explorer 9, Firefox, Chrome, Opera, Nokia Lumia 800, Nokia C7 (with Symbian 3), Android stock and Firefox beta browsers.

<table id="properties">
<tbody>
  <tr>
    <th>Name</th>
    <th>Value</th>
    <th>&nbsp;</th>
  </tr>
  <tr>
    <td nowrap>key1</td>
    <td><input type="text" name="property_key1" value="value1" size="70"/></td>
    <td class="data_item_options">
       <a class="buttonicon" href="javascript:deleteRow()" title="Delete row" onClick="deleteRow(this); return false;"></a>
    </td>
  </tr>
</tbody>
</table>

<table id="properties_rowtemplate" style="display:none" data-counter="0">
<tr>
 <td><input type="text" name="newproperty_name_\${counter}" value="" size="35"/></td>
 <td><input type="text" name="newproperty_value_\${counter}" value="" size="70"/></td>
 <td><a class="buttonicon" href="javascript:deleteRow()" title="Delete row" onClick="deleteRow(this); return false;"></a></td>
</tr>
</table>
<a class="action" href="javascript:addRow()" onclick="addRow('properties'); return false" title="Add new row">Add row</a><br/>
<br/>

- - - - 
// add row to html table, read html from row template
function addRow(sTableId) {
    // find destination and template tables, find first <tr>
    // in template. Wrap inner html around <tr> tags.
    // Keep track of counter to give unique field names.
    var table  = $("#"+sTableId);
    var template = $("#"+sTableId+"_rowtemplate");
    var htmlCode = "<tr>"+template.find("tr:first").html()+"</tr>";
    var id = parseInt(template.data("counter"),10)+1;
    template.data("counter", id);
    htmlCode = htmlCode.replace(/\${counter}/g, id);
    table.find("tbody:last").append(htmlCode);
}

// delete <TR> row, childElem is any element inside row
function deleteRow(childElem) {
    var row = $(childElem).closest("tr"); // find <tr> parent
    row.remove();
}

PS: I give all credits to the jQuery team; they deserve everything. JavaScript programming without jQuery - I don't even want think about that nightmare.

I wrote a simple jQuery plugin that lets you use a custom 'singleclick' event to differentiate a single-click from a double-click:

https://github.com/omriyariv/jquery-singleclick

$('#someDiv').on('singleclick', function(e) {
    // The event will be fired with a small delay.
    console.log('This is certainly a single-click');
}

For Kotlin:

Create two extensions, one for EditText and one for TextView

EditText:

fun EditText.clear() { text.clear() }

TextView:

fun TextView.clear() { text = "" }

and use it like

myEditText.clear()

myTextView.clear()

I don't know what qualifies as best but zxing has a qr code generator for java, is actively developed, and is liberally licensed.

I had the same issue on my debian server as the disk is full. No temp file could be created as no space left on device. After cleaning some files, it worked out fine.

C:\Users\\AppData\Roaming\Microsoft\Microsoft SQL Server\100\Tools\Shell

x86 is a 32 bit instruction set, x86_64 is a 64 bit instruction set... the difference is simple architecture. in case of windows os you better use the x86/32bit version for compatibility issues. in case of Linux you will not be able to use a 64 bit s/w if the os does not have the long mode flag.

Whatever I recommend if you have a windows 7 32 bit OS then go for 32bit or x86 binaries and as for Ubuntu 12.04 use command uname -a or grep lm /proc/cpuinfo (grep lm /proc/cpuinfo does not return value for 32 bit as 32 bit os does not has the cpuinfo flag) to know the architecture OS your OS then use the binaries according to your OS.

** Note. Remember you can always install 64 bit os in 32 bit system as long as it supports enhanced 64 bit.. 64 bit os works better some times for multi purpose work and also supports more ram than 32bits. also you can install 32bit s/w in 64 bit os..

** OS = Operating system.

Replace [ with nothing, then ] with nothing.

Since it's an external resource you'd need to go with JSONP because of the Same origin policy.
To do that you need to add the querystring parameter callback:

$.getJSON("http://myjsonsource?callback=?", function(data) {
    // Get the element with id summary and set the inner text to the result.
    $('#summary').text(data.result);
});

A common idiom to change every element of a list looks like this:

for i in range(len(L)):
    item = L[i]
    # ... compute some result based on item ...
    L[i] = result

This can be rewritten using enumerate() as:

for i, item in enumerate(L):
    # ... compute some result based on item ...
    L[i] = result

See enumerate.

If anyone want to use only number from 0 to 9 with imeOptions enable then use below line in your EditText

android:inputType="number|none"

This will only allow number and if you click on done/next button of keyboard your focus will move to next field.

Add the input values to a List and when you are done use List.ToArray() to get an array with the values.

How about using sort?

dir /b /s | sort

Here's an example I tested with:

dir /s /b /o:gn

d:\root0
d:\root0\root1
d:\root0\root1\folderA
d:\root0\root1\folderB
d:\root0\root1\file00.txt
d:\root0\root1\file01.txt
d:\root0\root1\folderA\fileA00.txt
d:\root0\root1\folderA\fileA01.txt
d:\root0\root1\folderB\fileB00.txt
d:\root0\root1\folderB\fileB01.txt

dir /s /b | sort

d:\root0
d:\root0\root1
d:\root0\root1\file00.txt
d:\root0\root1\file01.txt
d:\root0\root1\folderA
d:\root0\root1\folderA\fileA00.txt
d:\root0\root1\folderA\fileA01.txt
d:\root0\root1\folderB
d:\root0\root1\folderB\fileB00.txt
d:\root0\root1\folderB\fileB01.txt

To just get directories, use the /A:D parameter:

dir /a:d /s /b | sort

Alert boxes in JavaScript can only display pure text. You could use a JavaScript library like jQuery to display a modal instead?

This might be useful: http://jqueryui.com/dialog/

You can do it like this:

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
  <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
  <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
  <script>
  body {
    font-family: "Trebuchet MS", "Helvetica", "Arial",  "Verdana", "sans-serif";
    font-size: 62.5%;
}

  </script>
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

<div id="dialog" title="Basic dialog">
  <p>Image:</p>
  <img src="http://placehold.it/50x50" alt="Placeholder Image" />

</div>


</body>
</html>

I'd use this approach:

String randomString(final int length) {
    Random r = new Random(); // perhaps make it a class variable so you don't make a new one every time
    StringBuilder sb = new StringBuilder();
    for(int i = 0; i < length; i++) {
        char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
        sb.append(c);
    }
    return sb.toString();
}

If you want a byte[] you can do this:

byte[] randomByteString(final int length) {
    Random r = new Random();
    byte[] result = new byte[length];
    for(int i = 0; i < length; i++) {
        result[i] = r.nextByte();
    }
    return result;
}

Or you could do this

byte[] randomByteString(final int length) {
    Random r = new Random();
    StringBuilder sb = new StringBuilder();
    for(int i = 0; i < length; i++) {
        char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
        sb.append(c);
    }
    return sb.toString().getBytes();
}

You can use Perl::Tidy for Perl.

Download this Sqlite manager its the easiest one to use Sqlite manager

and drag and drop your fetched file on its running instance

only drawback of this Sqlite Manager it stop responding if you run some SQL statement that has Syntax Error in it.

So i Use Firefox Plugin Side by side also which you can find at FireFox addons

I tried to generate a form dynamically because the amount of questions depend on an object and for me the error was fixed when I added ngDefaultControl to my mat-form-field.

    <form [formGroup]="questionsForm">
        <ng-container *ngFor="let question of questions">
            <mat-form-field [formControlName]="question.id" ngDefaultControl>
                <mat-label>{{question.questionContent}}</mat-label>
                <textarea matInput rows="3" required></textarea>
            </mat-form-field>
        </ng-container>
        <button mat-raised-button (click)="sendFeedback()">Submit all questions</button>
    </form>

In sendFeedback() I get the value from my dynamic form by selecting the formgroup's value as such

  sendFeedbackAsAgent():void {
    if (this.questionsForm.valid) {
      console.log(this.questionsForm.value)
    }
  }

With WinForms you can use the ErrorProvider in conjunction with the Validating event to handle the validation of user input. The Validating event provides the hook to perform the validation and ErrorProvider gives a nice consistent approach to providing the user with feedback on any error conditions.

It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.

But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.

To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.

Define somewhere the consts :

private static final int BUTTON_LOCATION_X = 300;  // location x 
private static final int BUTTON_LOCATION_Y = 50;   // location y 
private static final int BUTTON_SIZE_X = 140;      // size height
private static final int BUTTON_SIZE_Y = 50;       // size width

and then below :

                JButton startButton = new JButton("Click Me To Start!");
                // startButton.setBounds(300, 50,140, 50 );
                startButton.setBounds(BUTTON_LOCATION_X
                                    , BUTTON_LOCATION_Y,
                                      BUTTON_SIZE_X, 
                                      BUTTON_SIZE_Y );
                contentPane.add(startButton);

where contentPane is the Container object that holds the entire frame :

 JFrame frame = new JFrame("Some name goes here");
 Container contentPane = frame.getContentPane();

I hope this helps , works great for me ...

From Oracle (but works in most SQL DBs):

SELECT LASTNAME, COUNT(*)
FROM STUDENTS
GROUP BY LASTNAME
HAVING COUNT(*) >= 3

P.S. it's faster one, because you have no Select withing Select methods here

I faced a similar issue. It seems correcting the path to XML makes this error to go away.

You can double.Parse("41.00027357629127");

According to mozilla:

A Map object can iterate its elements in insertion order - a for..of loop will return an array of [key, value] for each iteration.

and

Objects are similar to Maps in that both let you set keys to values, retrieve those values, delete keys, and detect whether something is stored at a key. Because of this, Objects have been used as Maps historically; however, there are important differences between Objects and Maps that make using a Map better.

An Object has a prototype, so there are default keys in the map. However, this can be bypassed using map = Object.create(null). The keys of an Object are Strings, where they can be any value for a Map. You can get the size of a Map easily while you have to manually keep track of size for an Object.

Use maps over objects when keys are unknown until run time, and when all keys are the same type and all values are the same type.

Use objects when there is logic that operates on individual elements.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

The iterability-in-order is a feature that has long been wanted by developers, in part because it ensures the same performance in all browsers. So to me that's a big one.

The myMap.has(key) method will be especially handy, and also the myMap.size property.

if you just want to show the file itself:

header('Content-Type: text/plain');
header('Content-Disposition: inline; filename="filename.txt"');
readfile(path);

REST is just a software architecture style for exposing resources.

• Use HTTP methods explicitly.
• Be stateless.
• Expose directory structure-like URIs.
• Transfer XML, JavaScript Object Notation (JSON), or both.

A typical REST call to return information about customer 34456 could look like:

http://example.com/customer/34456

Have a look at the IBM tutorial for REST web services

In ES6, you can do like this.

var key = "name";
var person = {[key]:"John"}; // same as var person = {"name" : "John"}
console.log(person); // should print  Object { name="John"}

    var key = "name";_x000D_
    var person = {[key]:"John"};_x000D_
    console.log(person); // should print  Object { name="John"}

Its called Computed Property Names, its implemented using bracket notation( square brackets) []

Example: { [variableName] : someValue }

Starting with ECMAScript 2015, the object initializer syntax also supports computed property names. That allows you to put an expression in brackets [], that will be computed and used as the property name.

For ES5, try something like this

var yourObject = {};

yourObject[yourKey] = "yourValue";

console.log(yourObject );

example:

var person = {};
var key = "name";

person[key] /* this is same as person.name */ = "John";

console.log(person); // should print  Object { name="John"}

    var person = {};_x000D_
    var key = "name";_x000D_
    _x000D_
    person[key] /* this is same as person.name */ = "John";_x000D_
    _x000D_
    console.log(person); // should print  Object { name="John"}

A short example to sort dictionary is desending order for Python3.

a1 = {'a':1, 'b':13, 'd':4, 'c':2, 'e':30}
a1_sorted_keys = sorted(a1, key=a1.get, reverse=True)
for r in a1_sorted_keys:
    print(r, a1[r])

Following will be the output

e 30
b 13
d 4

If you're using Python 2.6 or newer you can use the grouper recipe from the itertools module:

from itertools import izip_longest

def grouper(n, iterable, fillvalue=None):
    "grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
    args = [iter(iterable)] * n
    return izip_longest(fillvalue=fillvalue, *args)

Call like this:

for item1, item2 in grouper(2, l):
    # Do something with item1 and item2

Note that in Python 3.x you should use zip_longest instead of izip_longest.

It looks like you are using the HttpClient API, which I know nothing about, but you could write something similar to this using core Java.

try {

   HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
   con.setRequestMethod("HEAD");
   con.setConnectTimeout(5000); //set timeout to 5 seconds
   return (con.getResponseCode() == HttpURLConnection.HTTP_OK);

} catch (java.net.SocketTimeoutException e) {
   return false;
} catch (java.io.IOException e) {
   return false;
}

I think the problem is with the way you designed your data. To me in terms of semantics, it just doesn't make sense. What exactly is steps for?

Does it store the information of one company?

If that's the case steps should be an object (see KayakDave's answer) and each "step" should be an object property.

Does it store the information of multiple companies?

If that's the case, steps should be an array of objects.

$scope.steps=[{companyName: true, businessType: true},{companyName: false}]

In either case you can easily iterate through the data with one (two for 2nd case) ng-repeats.

start-all.sh & stop-all.sh : Used to start and stop hadoop daemons all at once. Issuing it on the master machine will start/stop the daemons on all the nodes of a cluster. Deprecated as you have already noticed.

start-dfs.sh, stop-dfs.sh and start-yarn.sh, stop-yarn.sh : Same as above but start/stop HDFS and YARN daemons separately on all the nodes from the master machine. It is advisable to use these commands now over start-all.sh & stop-all.sh

hadoop-daemon.sh namenode/datanode and yarn-deamon.sh resourcemanager : To start individual daemons on an individual machine manually. You need to go to a particular node and issue these commands.

Use case : Suppose you have added a new DN to your cluster and you need to start the DN daemon only on this machine,

bin/hadoop-daemon.sh start datanode

Note : You should have ssh enabled if you want to start all the daemons on all the nodes from one machine.

Hope this answers your query.

Some of the other examples (and even the documentation at the time of this writing) use outdated onAttach methods. Here is a full updated example.

Notes

• You don't want the Fragments talking directly to each other or to the Activity. That ties them to a particular Activity and makes reuse difficult.
• The solution is to make an callback listener interface that the Activity will implement. When the Fragment wants to send a message to another Fragment or its parent activity, it can do it through the interface.
• It is ok for the Activity to communicate directly to its child fragment public methods.
• Thus the Activity serves as the controller, passing messages from one fragment to another.

Solved this issue by increasing swap size:

https://askubuntu.com/questions/1075505/how-do-i-increase-swapfile-in-ubuntu-18-04

This property:

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", false);

...can be used to have no:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

However, I wouldn't consider this best practice.

Look out for this pitfal: http://www.vertstudios.com/blog/avoiding-ajax-newline-pitfall/

Searched several houres before I found there were some linebreaks in the included files.

To answer a little more conceptually:

SelectedValuePath defines which property (by its name) of the objects bound to the ListBox's ItemsSource will be used as the item's SelectedValue.

For example, if your ListBox is bound to a collection of Person objects, each of which has Name, Age, and Gender properties, SelectedValuePath=Name will cause the value of the selected Person's Name property to be returned in SelectedValue.

Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, SelectedValuePath cannot be used.

SelectedItem, meanwhile, returns the entire Person object currently selected.

(Here's a further example from MSDN, using TreeView)

Update: As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:

Note that these values are distinct from DisplayMemberPath (which is defined on ItemsControl, not Selector), but that property has similar behavior to SelectedValuePath: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

EXEC (@SQL)

No, there is no way for an webapp to receive push notification. What you could do is to wrap your webapp into a native app which has push notifications.

$("**:**input[type=text], :input[type='textarea']").css({width: '90%'});

Improvement to @madprops answer - solution as a django management command:

import MySQLdb
from django.conf import settings

from django.core.management.base import BaseCommand


class Command(BaseCommand):

    def handle(self, *args, **options):
        host = settings.DATABASES['default']['HOST']
        password = settings.DATABASES['default']['PASSWORD']
        user = settings.DATABASES['default']['USER']
        dbname = settings.DATABASES['default']['NAME']

        db = MySQLdb.connect(host=host, user=user, passwd=password, db=dbname)
        cursor = db.cursor()

        cursor.execute("ALTER DATABASE `%s` CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci'" % dbname)

        sql = "SELECT DISTINCT(table_name) FROM information_schema.columns WHERE table_schema = '%s'" % dbname
        cursor.execute(sql)

        results = cursor.fetchall()
        for row in results:
            print(f'Changing table "{row[0]}"...')
            sql = "ALTER TABLE `%s` convert to character set DEFAULT COLLATE DEFAULT" % (row[0])
            cursor.execute(sql)
        db.close()

Hope this helps anybody but me :)

To avoid deprecated opts and theme_rect use:

myplot + theme(panel.background = element_rect(fill='green', colour='red'))

To define your own custom theme, based on theme_gray but with some of your changes and a few added extras including control of gridline colour/size (more options available to play with at ggplot2.org):

theme_jack <- function (base_size = 12, base_family = "") {
    theme_gray(base_size = base_size, base_family = base_family) %+replace% 
        theme(
            axis.text = element_text(colour = "white"),
            axis.title.x = element_text(colour = "pink", size=rel(3)),
            axis.title.y = element_text(colour = "blue", angle=45),
            panel.background = element_rect(fill="green"),
            panel.grid.minor.y = element_line(size=3),
            panel.grid.major = element_line(colour = "orange"),
            plot.background = element_rect(fill="red")
    )   
}

To make your custom theme the default when ggplot is called in future, without masking:

theme_set(theme_jack())

If you want to change an element of the currently set theme:

theme_update(plot.background = element_rect(fill="pink"), axis.title.x = element_text(colour = "red"))

To store the current default theme as an object:

theme_pink <- theme_get()

Note that theme_pink is a list whereas theme_jack was a function. So to return the theme to theme_jack use theme_set(theme_jack()) whereas to return to theme_pink use theme_set(theme_pink).

You can replace theme_gray by theme_bw in the definition of theme_jack if you prefer. For your custom theme to resemble theme_bw but with all gridlines (x, y, major and minor) turned off:

theme_nogrid <- function (base_size = 12, base_family = "") {
    theme_bw(base_size = base_size, base_family = base_family) %+replace% 
        theme(
            panel.grid = element_blank()
    )   
}

Finally a more radical theme useful when plotting choropleths or other maps in ggplot, based on discussion here but updated to avoid deprecation. The aim here is to remove the gray background, and any other features that might distract from the map.

theme_map <- function (base_size = 12, base_family = "") {
    theme_gray(base_size = base_size, base_family = base_family) %+replace% 
        theme(
            axis.line=element_blank(),
            axis.text.x=element_blank(),
            axis.text.y=element_blank(),
            axis.ticks=element_blank(),
            axis.ticks.length=unit(0.3, "lines"),
            axis.ticks.margin=unit(0.5, "lines"),
            axis.title.x=element_blank(),
            axis.title.y=element_blank(),
            legend.background=element_rect(fill="white", colour=NA),
            legend.key=element_rect(colour="white"),
            legend.key.size=unit(1.2, "lines"),
            legend.position="right",
            legend.text=element_text(size=rel(0.8)),
            legend.title=element_text(size=rel(0.8), face="bold", hjust=0),
            panel.background=element_blank(),
            panel.border=element_blank(),
            panel.grid.major=element_blank(),
            panel.grid.minor=element_blank(),
            panel.margin=unit(0, "lines"),
            plot.background=element_blank(),
            plot.margin=unit(c(1, 1, 0.5, 0.5), "lines"),
            plot.title=element_text(size=rel(1.2)),
            strip.background=element_rect(fill="grey90", colour="grey50"),
            strip.text.x=element_text(size=rel(0.8)),
            strip.text.y=element_text(size=rel(0.8), angle=-90) 
        )   
}

Neer to specify exit code here so php not execute further

if ((isset($_POST['cancel'])) && ($_POST['cancel'] == 'cancel'))
{
    header('Location: page1.php');        
    exit(0); // require to exit here 
}

The Prototype creates new object by cloning existing object. So really when we think about prototype we can really think cloning or making a copy of something instead of making it up.

Uncaught TypeError: undefined is not a function example_app.js:7

This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined.

So what's on example_app.js line 7? Looks like this:

var tasks = new ExampleApp.Collections.Tasks(data.tasks);

There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks is undefined.

So lets look at where that is declared:

var Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks. But you never add it to the ExampleApp.Collections object, a place you later expect it to be.

Change that to this, and I bet you'd be good.

ExampleApp.Collections.Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.

In Javascript, when you execute a function, it's evaluated like:

expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does

That expression can be complex. So when you see undefined is not a function it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.

And in this case, it was because you didn't put something where you thought you did.

Delegated Alternative

In case anyone is using the delegated approach for their listener, use e.target (it will refer to the select element).

$('#myform').on('change', 'select', function (e) {
    var val = $(e.target).val();
    var text = $(e.target).find("option:selected").text(); //only time the find is required
    var name = $(e.target).attr('name');
}

JSFiddle Demo

Came here looking for an answer to this question myself. The slice answer is probably best, but I went ahead and created a "last" function just to practice extending prototypes, so I thought I would go ahead and share it. It has the added benefit over some other ones of letting you optionally count backwards through the array, and pull out, say, the second to last or third to last item. If you don't specify a count it just defaults to 1 and pulls out the last item.

Array.prototype.last = Array.prototype.last || function(count) {
    count = count || 1;
    var length = this.length;
    if (count <= length) {
        return this[length - count];
    } else {
        return null;
    }
};

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
arr.last(); // returns 9
arr.last(4); // returns 6
arr.last(9); // returns 1
arr.last(10); // returns null

I think it is much more simple solution:

window.location = (""+window.location).replace(/#[A-Za-z0-9_]*$/,'')+"#myAnchor"

This method does not reload the website, and sets the focus on the anchors which are needed for screen reader.

If you ever wondered how to do it using the new BDD style of Mockito:

willThrow(new Exception()).given(mockedObject).methodReturningVoid(...));

And for future reference one may need to throw exception and then do nothing:

willThrow(new Exception()).willDoNothing().given(mockedObject).methodReturningVoid(...));

The code below reads for any text files available in the directory which contains the script we are running. Then it opens every text file and stores the words of the text line into a list. After store the words we print each word line by line

import os, fnmatch

listOfFiles = os.listdir('.')
pattern = "*.txt"
store = []
for entry in listOfFiles:
    if fnmatch.fnmatch(entry, pattern):
        _fileName = open(entry,"r")
        if _fileName.mode == "r":
            content = _fileName.read()
            contentList = content.split(" ")
            for i in contentList:
                if i != '\n' and i != "\r\n":
                    store.append(i)

for i in store:
    print(i)

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

In any case, you can override height with max-height.

list(data_set.itertuples(index=False))

As of 17.1, the above will return a list of namedtuples.

If you want a list of ordinary tuples, pass name=None as an argument:

list(data_set.itertuples(index=False, name=None))

I have placed the following script on my system & I call it as a bash alias for when I want to quickly grab the full path to a file in the current dir:

#!/bin/bash
/usr/bin/find "$PWD" -maxdepth 1 -mindepth 1 -name "$1"

I am not sure why, but, on OS X when called by a script "$PWD" expands to the absolute path. When the find command is called on the command line, it doesn't. But it does what I want... enjoy.

You can do:

git log -S <whatever> --source --all

To find all commits that added or removed the fixed string whatever. The --all parameter means to start from every branch and --source means to show which of those branches led to finding that commit. It's often useful to add -p to show the patches that each of those commits would introduce as well.

Versions of git since 1.7.4 also have a similar -G option, which takes a regular expression. This actually has different (and rather more obvious) semantics, explained in this blog post from Junio Hamano.

As thameera points out in the comments, you need to put quotes around the search term if it contains spaces or other special characters, for example:

git log -S 'hello world' --source --all
git log -S "dude, where's my car?" --source --all

Here's an example using -G to find occurrences of function foo() {:

git log -G "^(\s)*function foo[(][)](\s)*{$" --source --all

It does not make sense to put your business layer in the Model for an MVC project.

Say that your boss decides to change the presentation layer to something else, you would be screwed! The business layer should be a separate assembly. A Model contains the data that comes from the business layer that passes to the view to display. Then on post for example, the model binds to a Person class that resides in the business layer and calls PersonBusiness.SavePerson(p); where p is the Person class. Here's what I do (BusinessError class is missing but would go in the BusinessLayer too):

Do you actually need more information than plain IEnumerable gives you? Just cast it to that and use foreach with it. I face exactly the same situation in some bits of Protocol Buffers, and I've found that casting to IEnumerable (or IList to access it like a list) works very well.

Add this to a static string utility class:

public static Stream ToStream(this string str)
{
    MemoryStream stream = new MemoryStream();
    StreamWriter writer = new StreamWriter(stream);
    writer.Write(str);
    writer.Flush();
    stream.Position = 0;
    return stream;
}

This adds an extension function so you can simply:

using (var stringStream = "My string".ToStream())
{

git revert -m allows to un-merge still keeping the history of both merge and un-do operation. Might be good for documenting probably.

control-shift-L should open the log(s) for you. this will by default be the messages log, but if you create the item that is creating the error the Compiler Log will show up (for me the box shows up in the bottom middle left).

if the messages log is the only log that shows up, simply re-execute the item that was causing the failure and the compiler log will show up

for instance, hit Control-shift-L then execute this

CREATE OR REPLACE FUNCTION TEST123() IS
BEGIN
VAR := 2;
end TEST123;

and you will see the message "Error(1,18): PLS-00103: Encountered the symbol ")" when expecting one of the following: current delete exists prior "

(You can also see this in "View--Log")

One more thing, if you are having a problem with a (function || package || procedure) if you do the coding via the SQL Developer interface (by finding the object in question on the connections tab and editing it the error will be immediately displayed (and even underlined at times)

Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.

Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/

This is definitely not the best way to do this but, I got it done by doing something like following.

String imageName = "my_image.png";
String replace = imageName.replace('.','~');
String[] split = replace.split("~");

System.out.println("Image name : " + split[0]);
System.out.println("Image extension : " + split[1]);

Output,

Image name : my_image
Image extension : png

Here I what I did to have an ImageButton which always have a width equals to its height (and avoid stupid empty margins in one direction...which I consider a as a bug of the SDK...):

I defined a SquareImageButton class which extends from ImageButton:

package com.myproject;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.ImageButton;

    public class SquareImageButton extends ImageButton {

        public SquareImageButton(Context context) {
        super(context);


        // TODO Auto-generated constructor stub
    }

    public SquareImageButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub

    }

    public SquareImageButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub

    }

    int squareDim = 1000000000;

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);


        int h = this.getMeasuredHeight();
        int w = this.getMeasuredWidth();
        int curSquareDim = Math.min(w, h);
        // Inside a viewholder or other grid element,
        // with dynamically added content that is not in the XML,
        // height may be 0.
        // In that case, use the other dimension.
        if (curSquareDim == 0)
            curSquareDim = Math.max(w, h);

        if(curSquareDim < squareDim)
        {
            squareDim = curSquareDim;
        }

        Log.d("MyApp", "h "+h+"w "+w+"squareDim "+squareDim);


        setMeasuredDimension(squareDim, squareDim);

    }

}

Here is my xml:

<com.myproject.SquareImageButton
            android:id="@+id/speakButton"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:scaleType="centerInside"
            android:src="@drawable/icon_rounded_no_shadow_144px"
            android:background="#00ff00"
            android:layout_alignTop="@+id/searchEditText"
            android:layout_alignBottom="@+id/searchEditText"
            android:layout_alignParentLeft="true"
           />

Works like a charm !

When want to get row size with size() function, below code can be used:

size(A,1)

Another usage for it:

[height, width] = size(A)

So, you can get 2 dimension of your matrix.

you need to assign the mysql_query to a variable (eg $result), then display this variable as you would a normal result from the database.

Another interesing way is to use $redact, which is one of the new aggregation features of MongoDB 2.6. If you are using 2.6, you don't need an $unwind which might cause you performance problems if you have large arrays.

db.test.aggregate([
    { $match: { 
         shapes: { $elemMatch: {color: "red"} } 
    }},
    { $redact : {
         $cond: {
             if: { $or : [{ $eq: ["$color","red"] }, { $not : "$color" }]},
             then: "$$DESCEND",
             else: "$$PRUNE"
         }
    }}]);

$redact "restricts the contents of the documents based on information stored in the documents themselves". So it will run only inside of the document. It basically scans your document top to the bottom, and checks if it matches with your if condition which is in $cond, if there is match it will either keep the content($$DESCEND) or remove($$PRUNE).

In the example above, first $match returns the whole shapes array, and $redact strips it down to the expected result.

Note that {$not:"$color"} is necessary, because it will scan the top document as well, and if $redact does not find a color field on the top level this will return false that might strip the whole document which we don't want.

You can get the names from the schema by doing

spark_df.schema.names

Printing the schema can be useful to visualize it as well

spark_df.printSchema()

s = s.Replace( """", "" )

Two quotes next to each other will function as the intended " character when inside a string.

I think you forgot the generic type definition:

public T GetEnumValue<T>(int intValue) where T : struct, IConvertible // <T> added

and you can improve it to be most convinient like e.g.:

public static T ToEnum<T>(this string enumValue) : where T : struct, IConvertible
{
    return (T)Enum.Parse(typeof(T), enumValue);
}

then you can do:

TestEnum reqValue = "Value1".ToEnum<TestEnum>();

You can assign one color to every functionality to make it more useful.

#define Color_Red "\33[0:31m\\]" // Color Start
#define Color_end "\33[0m\\]" // To flush out prev settings
#define LOG_RED(X) printf("%s %s %s",Color_Red,X,Color_end)

foo()
{
LOG_RED("This is in Red Color");
}

Like wise you can select different color codes and make this more generic.

With regards to @CrazyJugglerDrummer second method it would be:

elementsToChange.style.cursor = "http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur";

If you are developing for a modern browser, Instead of parsing the url parameters yourself- you can use the built in URL functions to do it for you like this:

const parser = new URL(url || window.location);
parser.searchParams.set(key, value);
window.location = parser.href;

#if !defined(MANUF) || !defined(SERIAL) || !defined(MODEL)

I suppose the easiest and the best solution is using OUTER APPLY. You only use one field with DISTINCT but to retrieve more data about that record, you utilize OUTER APPLY.

To test the solution, execute following query which firstly creates a temp table then retrieves data:

 DECLARE @tblFruit TABLE (tblFruit_ID int, tblFruit_FruitType varchar(10), tblFruit_FruitName varchar(50))
 SET NOCOUNT ON
 INSERT @tblFruit VALUES (1,'Citrus ','Orange')
 INSERT @tblFruit VALUES (2,'Citrus','Lime')
 INSERT @tblFruit VALUES (3,'Citrus','Lemon')
 INSERT @tblFruit VALUES (4,'Seed','Cherry')
 INSERT @tblFruit VALUES (5,'Seed','Banana')
   
SELECT DISTINCT (f.tblFruit_FruitType), outter_f.tblFruit_ID
FROM @tblFruit AS f
OUTER APPLY (
    SELECT TOP(1) *
    FROM @tblFruit AS inner_f
    WHERE inner_f.tblFruit_FruitType = f.tblFruit_FruitType
) AS outter_f

The result will be:

Citrus 1

Seed 4

I use this this code and works fine for me:

-(void)zoomToFitMapAnnotations:(MKMapView*)aMapView
{
    if([aMapView.annotations count] == 0)
        return;

    CLLocationCoordinate2D topLeftCoord;
    topLeftCoord.latitude = -90;
    topLeftCoord.longitude = 180;

    CLLocationCoordinate2D bottomRightCoord;
    bottomRightCoord.latitude = 90;
    bottomRightCoord.longitude = -180;

    for(MapViewAnnotation *annotation in mapView.annotations)
    {
        topLeftCoord.longitude = fmin(topLeftCoord.longitude, annotation.coordinate.longitude);
        topLeftCoord.latitude = fmax(topLeftCoord.latitude, annotation.coordinate.latitude);

        bottomRightCoord.longitude = fmax(bottomRightCoord.longitude, annotation.coordinate.longitude);
        bottomRightCoord.latitude = fmin(bottomRightCoord.latitude, annotation.coordinate.latitude);
    }

    MKCoordinateRegion region;
    region.center.latitude = topLeftCoord.latitude - (topLeftCoord.latitude - bottomRightCoord.latitude) * 0.5;
    region.center.longitude = topLeftCoord.longitude + (bottomRightCoord.longitude - topLeftCoord.longitude) * 0.5;
    region.span.latitudeDelta = fabs(topLeftCoord.latitude - bottomRightCoord.latitude) * 1.1; // Add a little extra space on the sides
    region.span.longitudeDelta = fabs(bottomRightCoord.longitude - topLeftCoord.longitude) * 1.1; // Add a little extra space on the sides

    region = [aMapView regionThatFits:region];
    [mapView setRegion:region animated:YES];
}

let bottomBorder = CALayer()
        bottomBorder.frame = CGRect(x: 0.0, y: calendarView.frame.size.height-1, width: calendarView.frame.width, height: 1.0)

                          '$poke[answer]')");
}

I don't think any of these answers are quite right/optimal. NameValueCollection not only doesn't distinguish between null values and missing values, it's also case-insensitive with regards to it's keys. Thus, I think a full solution would be:

public static bool ContainsKey(this NameValueCollection @this, string key)
{
    return @this.Get(key) != null 
        // I'm using Keys instead of AllKeys because AllKeys, being a mutable array,
        // can get out-of-sync if mutated (it weirdly re-syncs when you modify the collection).
        // I'm also not 100% sure that OrdinalIgnoreCase is the right comparer to use here.
        // The MSDN docs only say that the "default" case-insensitive comparer is used
        // but it could be current culture or invariant culture
        || @this.Keys.Cast<string>().Contains(key, StringComparer.OrdinalIgnoreCase);
}

mysqladmin -u root -p password

enter your current password

then

enter your new password

the default server name is your computer name, but you can use "." (Dot) instead of local server name.

another thing you should consider is maybe you installed sql server express edition. in this case you must enter ".\sqlexpress" as server name.

internal is for assembly scope (i.e. only accessible from code in the same .exe or .dll)

private is for class scope (i.e. accessible only from code in the same class).

@William Brendel answer provided three different use cases in nice way.

Use case 1:

Offical java documentation page on this provides same use-cases.

Within an instance method or a constructor, this is a reference to the current object — the object whose method or constructor is being called. You can refer to any member of the current object from within an instance method or a constructor by using this.

It covers two examples :

Using this with a Field and Using this with a Constructor

Use case 2:

Other use case which has not been quoted in this post: this can be used to synchronize the current object in a multi-threaded application to guard critical section of data & methods.

synchronized(this){
    // Do some thing. 
}

Use case 3:

Implementation of Builder pattern depends on use of this to return the modified object.

Refer to this post

Keeping builder in separate class (fluent interface)

A cross join produces a cartesian product between the two tables, returning all possible combinations of all rows. It has no on clause because you're just joining everything to everything.

A full outer join is a combination of a left outer and right outer join. It returns all rows in both tables that match the query's where clause, and in cases where the on condition can't be satisfied for those rows it puts null values in for the unpopulated fields.

This wikipedia article explains the various types of joins with examples of output given a sample set of tables.

Fontawesome has a perfect solution to this.

I implemented the same. just on your main .css file add this

.gi-2x{font-size: 2em;}
.gi-3x{font-size: 3em;}
.gi-4x{font-size: 4em;}
.gi-5x{font-size: 5em;}

In your example you just have to do this.

<div class = "jumbotron">
    <span class="glyphicon glyphicon-globe gi-5x"></span>
</div>  

You need to use setLayoutManager in the RecyclerView#onCreate() method. Before adding recyclerView to a view, it must have the LayoutManager set.

 private RecyclerView menuAsList;

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

    menuAsList = (RecyclerView) findViewById(R.id.recyclerView_mainMenu);
    menuAsList.setLayoutManager(new LinearLayoutManager(Home.this));

}

The answer from Dave Van den Eynde is now out of date. There are 2 important changes, from EF 4.1 onwards the ModelBuilder class is now DbModelBuilder and there is now a DecimalPropertyConfiguration.HasPrecision Method which has a signature of:

public DecimalPropertyConfiguration HasPrecision(
byte precision,
byte scale )

where precision is the total number of digits the db will store, regardless of where the decimal point falls and scale is the number of decimal places it will store.

Therefore there is no need to iterate through properties as shown but the can just be called from

public class EFDbContext : DbContext
{
   protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
   {
       modelBuilder.Entity<Class>().Property(object => object.property).HasPrecision(12, 10);

       base.OnModelCreating(modelBuilder);
   }
}

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

As others have said, you can/should prepend the string with @ (though you could also just escape the backslashes), but what they glossed over (that is, didn't bring it up despite making a change related to it) was the fact that, as I recently discovered, using \ at the beginning of a pathname, without . to represent the current directory, refers to the root of the current directory tree.

C:\foo\bar>cd \
C:\>

versus

C:\foo\bar>cd .\
C:\foo\bar>

(Using . by itself has the same effect as using .\ by itself, from my experience. I don't know if there are any specific cases where they somehow would not mean the same thing.)

You could also just leave off the leading .\ , if you want.

C:\foo>cd bar
C:\foo\bar>

In fact, if you really wanted to, you don't even need to use backslashes. Forwardslashes work perfectly well! (Though a single / doesn't alias to the current drive root as \ does.)

C:\>cd foo/bar
C:\foo\bar>

You could even alternate them.

C:\>cd foo/bar\baz
C:\foo\bar\baz>

...I've really gone off-topic here, though, so feel free to ignore all this if you aren't interested.

You can use column indices (letters) like this:

import pandas as pd
import numpy as np
file_loc = "path.xlsx"
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
print(df)

[Corresponding documentation][1]:

usecolsint, str, list-like, or callable default None

• If None, then parse all columns.
• If str, then indicates comma separated list of Excel column letters and column ranges (e.g. “A:E” or “A,C,E:F”). Ranges are inclusive of both sides.
• If list of int, then indicates list of column numbers to be parsed.

• If list of string, then indicates list of column names to be parsed.

  New in version 0.24.0.

• If callable, then evaluate each column name against it and parse the column if the callable returns True.

Returns a subset of the columns according to behavior above.

New in version 0.24.0.

$prompt: /path/to/script and hit enter. Note you need to make sure the script has execute permissions.

As others have pointed out, you can only use werkzeug.server.shutdown from a request handler. The only way I've found to shut down the server at another time is to send a request to yourself. For example, the /kill handler in this snippet will kill the dev server unless another request comes in during the next second:

import requests
from threading import Timer
from flask import request
import time

LAST_REQUEST_MS = 0
@app.before_request
def update_last_request_ms():
    global LAST_REQUEST_MS
    LAST_REQUEST_MS = time.time() * 1000


@app.route('/seriouslykill', methods=['POST'])
def seriouslykill():
    func = request.environ.get('werkzeug.server.shutdown')
    if func is None:
        raise RuntimeError('Not running with the Werkzeug Server')
    func()
    return "Shutting down..."


@app.route('/kill', methods=['POST'])
def kill():
    last_ms = LAST_REQUEST_MS
    def shutdown():
        if LAST_REQUEST_MS <= last_ms:  # subsequent requests abort shutdown
            requests.post('http://localhost:5000/seriouslykill')
        else:
            pass

    Timer(1.0, shutdown).start()  # wait 1 second
    return "Shutting down..."

Method canOpenUrl is in iOS 9 (due to privacy) changed and is not free to use any more. Your banner provider checks for installed apps so that they do not show banners for an app that is already installed.

That gives all the log statements like

-canOpenURL: failed for URL: "kindle://home" - error: "This app is not allowed to query for scheme kindle"

The providers should update their logic for this.

If you need to query for installed apps/available schemes you need to add them to your info.plist file.

Add the key 'LSApplicationQueriesSchemes' to your plist as an array. Then add strings in that array like 'kindle'.

Of course this is not really an option for the banner ads (since those are dynamic), but you can still query that way for your own apps or specific other apps like Twitter and Facebook.

Documentation of the canOpenUrl: method canOpenUrl:

Simple. When I use it, it's a modern dynamic language, when you use it, it's merely a scripting language!

If you're using OS X and used the standard install, Delete vagrant's old curl and it should now work

If you want to fit other type of models, like a dose-response curve using logistic models you would also need to create more data points with the function predict if you want to have a smoother regression line:

fit: your fit of a logistic regression curve

#Create a range of doses:
mm <- data.frame(DOSE = seq(0, max(data$DOSE), length.out = 100))
#Create a new data frame for ggplot using predict and your range of new 
#doses:
fit.ggplot=data.frame(y=predict(fit, newdata=mm),x=mm$DOSE)

ggplot(data=data,aes(x=log10(DOSE),y=log(viability)))+geom_point()+
geom_line(data=fit.ggplot,aes(x=log10(x),y=log(y)))

Your shell_exec is executed by www-data user, from its directory. You can try

putenv("PATH=/home/user/bin/:" .$_ENV["PATH"]."");

Where your script is located in /home/user/bin Later on you can

$output = "<pre>".shell_exec("scriptname v1 v2")."</pre>";
echo $output;

To display the output of command. (Alternatively, without exporting path, try giving entire path of your script instead of just ./script.sh

I modified the PHP answer of Olivier a bit to:

• print out the results in which the string was found
• omit tables without results
• also show output if column names match the search input

• show total number of results

  function searchAllDB($search){
      global $mysqli;
  
      $out = "";
      $total = 0;
      $sql = "SHOW TABLES";
      $rs = $mysqli->query($sql);
      if($rs->num_rows > 0){
          while($r = $rs->fetch_array()){
              $table = $r[0];
              $sql_search = "select * from ".$table." where ";
              $sql_search_fields = Array();
              $sql2 = "SHOW COLUMNS FROM ".$table;
              $rs2 = $mysqli->query($sql2);
              if($rs2->num_rows > 0){
                  while($r2 = $rs2->fetch_array()){
                      $colum = $r2[0];
                      $sql_search_fields[] = $colum." like('%".$search."%')";
                      if(strpos($colum,$search))
                      {
                          echo "FIELD NAME: ".$colum."\n";
                      }
                  }
                  $rs2->close();
              }
              $sql_search .= implode(" OR ", $sql_search_fields);
              $rs3 = $mysqli->query($sql_search);
              if($rs3 && $rs3->num_rows > 0)
              {
                  $out .= $table.": ".$rs3->num_rows."\n";
                  if($rs3->num_rows > 0){
                      $total += $rs3->num_rows;
                      $out.= print_r($rs3->fetch_all(),1);
                      $rs3->close();
                  }
              }
          }
          $out .= "\n\nTotal results:".$total;
          $rs->close();
      }
      return $out;
  }
  

one way: List.AddRange() depending on the types?

There's a much easier way than recompiling PHP. Just yum install the required mbstring library:

Example: How to install PHP mbstring on CentOS 6.2

yum --enablerepo=remi install php-mbstring

Oh, and don't forget to restart apache afterward.

Using \b can yield surprising results. You would be better off figuring out what separates a word from its definition and incorporating that information into your pattern.

In the docker containers(centos based images) it is located at

Try this set of code to download a CSV file from the server.

byte[] Content= File.ReadAllBytes(FilePath); //missing ;
Response.ContentType = "text/csv";
Response.AddHeader("content-disposition", "attachment; filename=" + fileName + ".csv");
Response.BufferOutput = true;
Response.OutputStream.Write(Content, 0, Content.Length);
Response.End();

This worked for me:

$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(false);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(10);

be sure to add setAuzoSize(false), before the setWidth(); as Rolland mentioned

You have to go into your mySQL settings and change the settings to Legacy authentication. I use mysql community installer and it allows you to go back and reconfigure the settings. Create a new user, and choose standard authentication, choose a password, thats it. Its that simple!!!

Do I have to add an encapsulating <div> or <span>?

I think you do. The only thing that comes to mind is padding, but for that you would have to know the image's dimensions beforehand.

I was looking to find the answer to this question too, but the accepted answer was breaking for me. Apparently using window.innerWidth isn't portable. It does work in some browsers, but I noticed Firefox didn't like it.

Gregg Tavares posted a great resource here that addresses this issue directly: http://webglfundamentals.org/webgl/lessons/webgl-anti-patterns.html (See anti-pattern #'s 3 and 4).

Using canvas.clientWidth instead of window.innerWidth seems to work nicely.

Here's Gregg's suggested render loop:

function resize() {
  var width = gl.canvas.clientWidth;
  var height = gl.canvas.clientHeight;
  if (gl.canvas.width != width ||
      gl.canvas.height != height) {
     gl.canvas.width = width;
     gl.canvas.height = height;
     return true;
  }
  return false;
}

var needToRender = true;  // draw at least once
function checkRender() {
   if (resize() || needToRender) {
     needToRender = false;
     drawStuff();
   }
   requestAnimationFrame(checkRender);
}
checkRender();

You could also use INDEX MATCH, which is more "powerful" than vlookup. This would give you exactly what you are looking for:

What you are describing is actually what FontAwesome is doing already. They apply the FontAwesome font-family to the ::before pseudo element of any element that has a class that starts with "icon-".

[class^="icon-"]:before,
[class*=" icon-"]:before {
  font-family: FontAwesome;
  font-weight: normal;
  font-style: normal;
  display: inline-block;
  text-decoration: inherit;
}

Then they use the pseudo element ::before to place the icon in the element with the class. I just went to http://fortawesome.github.com/Font-Awesome/ and inspected the code to find this:

.icon-cut:before {
  content: "\f0c4";
}

So if you are looking to add the icon again, you could use the ::after element to achieve this. Or for your second part of your question, you could use the ::after pseudo element to insert the bullet character to look like a list item. Then use absolute positioning to place it to the left, or something similar.

i:after{ content: '\2022';}

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

You might mean this:

var unEnumeratedArray = [];
var wtfObject = {
                 key    : 'val', 
                 0      : (undefined = 'Look, I\'m defined'),
                 'new'  : 'keyword', 
                 '{!}'  : 'use bracket syntax',
                 '        ': '8 spaces'
                };

for(var key in wtfObject){
    unEnumeratedArray[key] = wtfObject[key];
}
console.log('HAS KEYS PER VALUE NOW:', unEnumeratedArray, unEnumeratedArray[0], 
             unEnumeratedArray.key, unEnumeratedArray['new'], 
             unEnumeratedArray['{!}'], unEnumeratedArray['        ']);

You can set an enumerable for an Object like: ({})[0] = 'txt'; and you can set a key for an Array like: ([])['myKey'] = 'myVal';

Hope this helps :)

Did you include "Management Tools" as a chosen option during setup?

Ensure this option is selected, and SQL Server Management Studio will be installed on the machine.

Loose coupling is and answer to to old style hardcoded dependencies and related issues issues like frequent recompilation when anything changes and code reuse. It stresses on implementing the worker logic in components and avoiding solution specific wire up code there.

Loose Coupling = IoC See this for easier explanation.

To be quite honest, regular expressions are not the best idea for this type of parsing. The regular expression you posted will probably work great for simple cases, but if things get more complex you are going to have huge problems (same reason why you cant reliably parse HTML with regular expressions). I know you probably don't want to hear this, I know I didn't when I asked the same type of questions, but string parsing became WAY more reliable for me after I stopped trying to use regular expressions for everything.

jTopas is an AWESOME tokenizer that makes it quite easy to write parsers by hand (I STRONGLY suggest jtopas over the standard java scanner/etc.. libraries). If you want to see jtopas in action, here are some parsers I wrote using jTopas to parse this type of file

If you are parsing XML files, you should be using an xml parser library. Dont do it youself unless you are just doing it for fun, there are plently of proven options out there

You can also use this function,

function optionDisable(selectId, optionIndices)
{
    for (var idxCount=0; idxCount<optionIndices.length;idxCount++)
    {
        document.getElementById(selectId).children[optionIndices[idxCount]].disabled="disabled";
        document.getElementById(selectId).children[optionIndices[idxCount]].style.backgroundColor = '#ccc';
        document.getElementById(selectId).children[optionIndices[idxCount]].style.color = '#f00';
    }
}

You can change it in the webpack.dev.js file in config folder.

Your broadcast receiver must specify android:exported="true" to receive broadcasts created outside your own application. My broadcast receiver is defined in the manifest as follows:

<receiver
    android:name=".IncomingSmsBroadcastReceiver"
    android:enabled="true"
    android:exported="true" >
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

As noted below, exported="true" is the default, so you can omit this line. I've left it in so that the discussion comments make sense.

I know this is old but I came upon this post quickly thinking Concat would be my answer. Union worked great for me. Note, it returns only unique values but knowing that I was getting unique values anyway this solution worked for me.

namespace TestProject
{
    public partial class Form1 :Form
    {
        public Form1()
        {
            InitializeComponent();

            List<string> FirstList = new List<string>();
            FirstList.Add("1234");
            FirstList.Add("4567");

            // In my code, I know I would not have this here but I put it in as a demonstration that it will not be in the secondList twice
            FirstList.Add("Three");  

            List<string> secondList = GetList(FirstList);            
            foreach (string item in secondList)
                Console.WriteLine(item);
        }

        private List<String> GetList(List<string> SortBy)
        {
            List<string> list = new List<string>();
            list.Add("One");
            list.Add("Two");
            list.Add("Three");

            list = list.Union(SortBy).ToList();

            return list;
        }
    }
}

The output is:

One
Two
Three
1234
4567
