Why eat Toast, when you can have the entire Snackbar: https://developer.android.com/reference/android/support/design/widget/Snackbar.html

Snackbar > Toast, Custom Toast, Crouton

Something shorter version based off Yermo Lamers' suggestion, this seems to work alright. Even with basic animations like fade in/out and even crazy batman newspaper rotate. http://jsfiddle.net/ketwaroo/mXy3E/

$('.modal').on('show.bs.modal', function(event) {
    var idx = $('.modal:visible').length;
    $(this).css('z-index', 1040 + (10 * idx));
});
$('.modal').on('shown.bs.modal', function(event) {
    var idx = ($('.modal:visible').length) -1; // raise backdrop after animation.
    $('.modal-backdrop').not('.stacked').css('z-index', 1039 + (10 * idx));
    $('.modal-backdrop').not('.stacked').addClass('stacked');
});

You can use Reflection to obtain the actual names of the properties.

http://www.csharp-examples.net/reflection-property-names/

If you need a way to assign a "String Name" to a property, why don't you write an attribute that you can reflect over to get the string name?

[StringName("MyStringName")]
private string MyProperty
{
    get { ... }
}

Use query selectors, examples:

document.querySelectorAll(' input[name], [id|=view], [class~=button] ')

input[name] Inputs elements with name property.

[id|=view] Elements with id that start with view-.

[class~=button] Elements with the button class.

There are essentially three different ways how to express something like if-then-else in Prolog. To compare them consider char_class/2. For a and b the class should be ab and other for all other terms. One could write this clumsily like so:

char_class(a, ab).
char_class(b, ab).
char_class(X, other) :-
   dif(X, a),
   dif(X, b).

?- char_class(Ch, Class).
   Ch = a, Class = ab
;  Ch = b, Class = ab
;  Class = other,
   dif(Ch, a), dif(Ch, b).

To write things more compactly, an if-then-else construct is needed. Prolog has a built-in one:

?- ( ( Ch = a ; Ch = b ) -> Class = ab ; Class = other ).
   Ch = a, Class = ab.

While this answer is sound, it is incomplete. Just the first answer from ( Ch = a ; Ch = b ) is given. The other answers are chopped away. Not very relational, indeed.

A better construct, often called a "soft cut" (don't believe the name, a cut is a cut is a cut), gives slightly better results (this is in YAP):

?- ( ( Ch = a ; Ch = b ) *-> Class = ab ; Class = other ).
   Ch = a, Class = ab
;  Ch = b, Class = ab.

Alternatively, SICStus has if/3 with very similar semantics:

?- if( ( Ch = a ; Ch = b ), Class = ab , Class = other ).
   Ch = a, Class = ab
;  Ch = b, Class = ab.

So the last answer is still suppressed. Now enter library(reif) for SICStus, YAP, and SWI. Install it and say:

?- use_module(library(reif)).

?- if_( ( Ch = a ; Ch = b ), Class = ab , Class = other ).
   Ch = a, Class = ab
;  Ch = b, Class = ab
;  Class = other,
   dif(Ch, a), dif(Ch, b).

Note that all the if_/3 is compiled away to a wildly nested if-then-else for

char_class(Ch, Class) :-
   if_( ( Ch = a ; Ch = b ), Class = ab , Class = other ).

which expands in YAP 6.3.4 to:

char_class(A,B) :-
   ( A\=a
   ->
     ( A\=b
     ->
       B=other
     ;
       ( A==b
       ->
         B=ab
       )
     ;
       A=b,
       B=ab
     ;
       dif(A,b),
       B=other
     )
   ;
     ( A==a
     ->
       B=ab
     )
   ;
     A=a,
     B=ab
   ;
     dif(A,a),
     ( A\=b
     ->
       B=other
     ;
       ( A==b
       ->
         B=ab
       )
     ;
       A=b,
       B=ab
     ;
       dif(A,b),
       B=other
     )
   ).

its an implementation of anonymouse class object creation to give ease of writing less code and to save time

Because a string variable is a reference, not an instance.

Initializing it to Empty by default would have been possible but it would have introduced a lot of inconsistencies all over the board.

I happened to try this so I could see the list of files first:

git status | grep "modified:" | awk '{print "git add  " $2}' > file.sh

cat ./file.sh

execute:

chmod a+x file.sh
./file.sh 

Edit: (see comments) This could be achieved in one step:

git status | grep "modified:" | awk '{print $2}' | xargs git add && git status

Let's go in reverse order:

• Log.e: This is for when bad stuff happens. Use this tag in places like inside a catch statement. You know that an error has occurred and therefore you're logging an error.

• Log.w: Use this when you suspect something shady is going on. You may not be completely in full on error mode, but maybe you recovered from some unexpected behavior. Basically, use this to log stuff you didn't expect to happen but isn't necessarily an error. Kind of like a "hey, this happened, and it's weird, we should look into it."

• Log.i: Use this to post useful information to the log. For example: that you have successfully connected to a server. Basically use it to report successes.

• Log.d: Use this for debugging purposes. If you want to print out a bunch of messages so you can log the exact flow of your program, use this. If you want to keep a log of variable values, use this.

• Log.v: Use this when you want to go absolutely nuts with your logging. If for some reason you've decided to log every little thing in a particular part of your app, use the Log.v tag.

And as a bonus...

• Log.wtf: Use this when stuff goes absolutely, horribly, holy-crap wrong. You know those catch blocks where you're catching errors that you never should get...yeah, if you wanna log them use Log.wtf

If your docker.service enabled on system startup

$ sudo systemctl enable docker

and your services in your docker-compose.yml has

restart: always

all of the services run when you reboot your system if you run below command only once

The error for me was:

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:percent:26.0.2] AndroidManifest.xml:25:13-35
    is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
    Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:23:9-25:38 to override.

The solution for me was in my project Gradle file I needed to bump my com.google.gms:google-services version.

I was using version 3.1.1:

classpath 'com.google.gms:google-services:3.1.1

And the error resolved after I bumped it to version 3.2.1:

classpath 'com.google.gms:google-services:3.2.1

I had just upgraded all my libraries to the latest including v27.1.1 of all the support libraries and v15.0.0 of all the Firebase libraries when I saw the error.

Update Answer (after wwdc 2016):

IOS apps will require secure HTTPS connections by the end of 2016

App Transport Security, or ATS, is a feature that Apple introduced in iOS 9. When ATS is enabled, it forces an app to connect to web services over an HTTPS connection rather than non secure HTTP.

However, developers can still switch ATS off and allow their apps to send data over an HTTP connection as mentioned in above answers. At the end of 2016, Apple will make ATS mandatory for all developers who hope to submit their apps to the App Store. link

If you're using Java 9, there's an easy way with less number of lines without needing to initialize or add method.

List<String> list = List.of("first", "second", "third");

Instead of using divider in dialog, use the view in the custom layout and set the layout as custom layout in dialog.

        android:paddingBottom="10dp"
        android:paddingTop="10dp"
        android:text="AlertDialog"

    </ScrollView>
</RelativeLayout>

activity.java:

public void showPopUp(String title, String text) {

    LayoutInflater inflater = getLayoutInflater();
    View alertLayout = inflater.inflate(R.layout.custom_popup, null);

    TextView txtContent = alertLayout.findViewById(R.id.txtPopup);
    txtContent.setText(text);

    TextView txtTitle = alertLayout.findViewById(R.id.txtTitle);
    txtTitle.setText(title);

The base dn is dc=example,dc=com.

I don't know about openca, but I will try this answer since you got very little traffic so far.

A base dn is the point from where a server will search for users. So I would try to simply use admin as a login name.

If openca behaves like most ldap aware applications, this is what is going to happen :

1. An ldap search for the user admin will be done by the server starting at the base dn (dc=example,dc=com).
2. When the user is found, the full dn (cn=admin,dc=example,dc=com) will be used to bind with the supplied password.
3. The ldap server will hash the password and compare with the stored hash value. If it matches, you're in.

Getting step 1 right is the hardest part, but mostly because we don't get to do it often. Things you have to look out for in your configuraiton file are :

• The dn your application will use to bind to the ldap server. This happens at application startup, before any user comes to authenticate. You will have to supply a full dn, maybe something like cn=admin,dc=example,dc=com.
• The authentication method. It is usually a "simple bind".
• The user search filter. Look at the attribute named objectClass for your admin user. It will be either inetOrgPerson or user. There will be others like top, you can ignore them. In your openca configuration, there should be a string like (objectClass=inetOrgPerson). Whatever it is, make sure it matches your admin user's object Class. You can specify two object class with this search filter (|(objectClass=inetOrgPerson)(objectClass=user)).

Download an LDAP Browser, such as Apache's Directory Studio. Connect using your application's credentials, so you will see what your application sees.

For me, what worked on Windows was running Command Prompt as administrator and then installing pipenv globally: python -m pip install pipenv.

Here are screenshots for SQL Server 2008 R2, using SSRS Report Designer in Visual Studio 2010.

I have done screenshots as some of the dialogs are not easy to find.

1: Add the group

2: Specify the field you want to group on

3: Now click on the group in the 'Row Groups' selector, directly below the report designer

4: F4 to select property pane; expand 'Group' and set Group > PageBreak > BreakLocation = 'Between', then enter the expression you want for Group > PageName

5: Here is an example expression

Here is the result of the report exported to Excel, with tabs named according to the PageName expression

Very easy:

handleSubmit(e){_x000D_
    e.preventDefault();_x000D_
    e.target.reset();_x000D_
}

<form onSubmit={this.handleSubmit.bind(this)}>_x000D_
  ..._x000D_
</form>

Good luck :)

Short answer: download Linux Device Drivers and read the chapter on memory management.

Seriously, there are a lot of subtle issues related to kernel memory management that you need to understand - I spend a lot of my time debugging problems with it.

vmalloc() is very rarely used, because the kernel rarely uses virtual memory. kmalloc() is what is typically used, but you have to know what the consequences of the different flags are and you need a strategy for dealing with what happens when it fails - particularly if you're in an interrupt handler, like you suggested.

This will work like a charm.

background-image:url("http://assets.toptal.io/uploads/blog/category/logo/4/php.png");
background-repeat: no-repeat;
background-size: contain;

$('div').attr('class', function(i, c){
    return c.replace(/(^|\s)color-\S+/g, '');
});

Sometimes I just append an empty string to an object that might be null.

object x = null;
string y = (x + "").ToString();

This will never throw an exception and always return an empty string if null and doesn't require if then logic.

var data = {_x000D_
  "items": [{_x000D_
    "id": 1,_x000D_

//Filter an array of numbers to include numbers that are not bigger than zero._x000D_
//Exact Data you don't want..._x000D_
var returnedOppositeData = $.grep(data.items, function(element) {_x000D_
  return element.category === "cat1";_x000D_
}, true);_x000D_
console.log(returnedOppositeData);

The $.grep() method eliminates items from an array as necessary so that only remaining items carry a given search. The test is a function that is passed an array item and the index of the item within the array. Only if the test returns true will the item be in the result array.

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

For those who need the input file to open directly the camera, you just have to declare capture parameter to the input file, like this :

<input type="file" accept="image/*" capture>

awk 'BEGIN {FS=" "} {printf "\047%s\047 ", $1}'

As DPA says, the easiest way to generate a war file of your project is through the IDE. Open the Files tab from your left hand panel, right click on the build.xml file and tell it what type of ant target you want to run.

The initialize method is called after all @FXML annotated members have been injected. Suppose you have a table view you want to populate with data:

class MyController { 
    @FXML
    TableView<MyModel> tableView; 

    public MyController() {
        tableView.getItems().addAll(getDataFromSource()); // results in NullPointerException, as tableView is null at this point. 
    }

    @FXML
    public void initialize() {
        tableView.getItems().addAll(getDataFromSource()); // Perfectly Ok here, as FXMLLoader already populated all @FXML annotated members. 
    }
}

All your problems derive from this

byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;

Which are enclosed in a try, catch block, the problem is that in case the program found an exception you are not returning anything. Put it like this (modify it as your program logic stands):

public static byte[] encrypt(String toEncrypt) throws Exception{
    try{
        String plaintext = toEncrypt;
        String key = "01234567890abcde";
        String iv = "fedcba9876543210";

        SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
        IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

        Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
        cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
        byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());

        return encrypted;
    } catch(Exception e){
        return null;            // Always must return something
    }
}

For the second one you must catch the Exception from the encrypt method call, like this (also modify it as your program logic stands):

public void actionPerformed(ActionEvent e)
  .
  .
  .
    try {
        byte[] encrypted = encrypt(concatURL);
        String encryptedString = bytesToHex(encrypted);
        content.removeAll();
        content.add(new JLabel("Concatenated User Input -->" + concatURL));

        content.add(encryptedTextField);
    setContentPane(content);
    } catch (Exception exc) {
        // TODO: handle exception
    }
}

The lessons you must learn from this:

• A method with a return-type must always return an object of that type, I mean in all possible scenarios
• All checked exceptions must always be handled

Another way to check the target platform of a .NET assembly is inspecting the assembly with .NET Reflector...

@#~#€~! I've just realized that the new version is not free! So, correction, if you have a free version of .NET reflector, you can use it to check the target platform.

nullptr is always a pointer type. 0 (aka. C's NULL bridged over into C++) could cause ambiguity in overloaded function resolution, among other things:

f(int);
f(foo *);

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

Try this...

Calendar calendar = Calendar.getInstance();
String currentDate24Hrs = (String) DateFormat.format(
            "MM/dd/yyyy kk:mm:ss", calendar.getTime());
Log.i("DEBUG_TAG", "24Hrs format date: " + currentDate24Hrs);

Its Very simple

variable.GetType().Name

it will return your datatype of your variable

You can use ARG - see https://docs.docker.com/engine/reference/builder/#arg

The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag. If a user specifies a build argument that was not defined in the Dockerfile, the build outputs an error.

Regarding coding style:

Most coding standards no matter language ban multiple return statements from a single function as bad practice.

(Although personally I would say there are several cases where multiple return statements do make sense: text/data protocol parsers, functions with extensive error handling etc)

The consensus from all those industry coding standards is that the expression should be written as:

int result;

if(A > B)
{
  result = A+1;
}
else
{
  result = A-1;
}
return result;

Regarding efficiency:

The above example and the two examples in the question are all completely equivalent in terms of efficiency. The machine code in all these cases have to compare A > B, then branch to either the A+1 or the A-1 calculation, then store the result of that in a CPU register or on the stack.

The Chrome team has recently implemented a feature that tells the browser to launch the page fullscreen when the user has added it to the home screen. It is similar to the iOS Safari model.

<meta name="mobile-web-app-capable" content="yes">

Try to see if it works in Incognito Mode. If it does, then it's a bug in recent Chrome. On my computer the following fix worked:

1. Quit Chrome
2. Delete your full Chrome cache folder
3. Restart Chrome

You can also use the tab character '\t' to represent a tab, instead of "\t".

char c ='t';
char c =(char)9;

Can we see your import block? because it seems that you have imported the wrong Iterator class.

The one you should use is java.util.Iterator

To make sure, try:

java.util.Iterator iter = hm.keySet().iterator();

I personally suggest the following:

Map Declaration using Generics and declaration using the Interface Map<K,V> and instance creation using the desired implementation HashMap<K,V>

Map<Integer, String> hm = new HashMap<>();

and for the loop:

for (Integer key : hm.keySet()) {
    System.out.println("Key = " + key + " - " + hm.get(key));
}

UPDATE 3/5/2015

Found out that iterating over the Entry set will be better performance wise:

for (Map.Entry<Integer, String> entry : hm.entrySet()) {
    Integer key = entry.getKey();
    String value = entry.getValue();

}

UPDATE 10/3/2017

For Java8 and streams, your solution will be (Thanks @Shihe Zhang)

 hm.forEach((key, value) -> System.out.println(key + ": " + value))

npm uninstall yarn removes the yarn packages that are installed via npm but what yarn does underneath the hood is, it installs a software named yarn in your PC. If you have installed in Windows, Go to add or remove programs and then search for yarn and uninstall it then you are good to go.

set echo off
spool c:\test.csv 
select /*csv*/ username, user_id, created from all_users;
spool off;

if you right click on any of the rows you can export the item or the entire data set as HAR which appears to be a JSON format.

It shouldn't be terribly difficult to script up something to transform that to a csv if you really need it in excel, but if you're already scripting you might as well just use the script to ask your questions of the data.

If anyone knows how to drive the "load page, export data" part of the process from the command line I'd be quite interested in hearing how

Nor Kelsey, nor Brendan solutions does not works for me in Visual Studio 2015 Community.

Here is my brief steps how to create service with installer:

1. Run Visual Studio, Go to File->New->Project
2. Select .NET Framework 4, in 'Search Installed Templates' type 'Service'
3. Select 'Windows Service'. Type Name and Location. Press OK.
4. Double click Service1.cs, right click in designer and select 'Add Installer'
5. Double click ProjectInstaller.cs. For serviceProcessInstaller1 open Properties tab and change 'Account' property value to 'LocalService'. For serviceInstaller1 change 'ServiceName' and set 'StartType' to 'Automatic'.

6. Double click serviceInstaller1. Visual Studio creates serviceInstaller1_AfterInstall event. Write code:

   private void serviceInstaller1_AfterInstall(object sender, InstallEventArgs e)
   {
       using (System.ServiceProcess.ServiceController sc = new 
       System.ServiceProcess.ServiceController(serviceInstaller1.ServiceName))
       {
           sc.Start();
       }
   }
   

7. Build solution. Right click on project and select 'Open Folder in File Explorer'. Go to bin\Debug.

8. Create install.bat with below script:

   :::::::::::::::::::::::::::::::::::::::::
   :: Automatically check & get admin rights
   :::::::::::::::::::::::::::::::::::::::::
   @echo off
   CLS 
   ECHO.
   ECHO =============================
   ECHO Running Admin shell
   ECHO =============================
   
   :checkPrivileges 
   NET FILE 1>NUL 2>NUL
   if '%errorlevel%' == '0' ( goto gotPrivileges ) else ( goto getPrivileges ) 
   
   :getPrivileges 
   if '%1'=='ELEV' (shift & goto gotPrivileges)  
   ECHO. 
   ECHO **************************************
   ECHO Invoking UAC for Privilege Escalation 
   ECHO **************************************
   
   setlocal DisableDelayedExpansion
   set "batchPath=%~0"
   setlocal EnableDelayedExpansion
   ECHO Set UAC = CreateObject^("Shell.Application"^) > "%temp%\OEgetPrivileges.vbs" 
   ECHO UAC.ShellExecute "!batchPath!", "ELEV", "", "runas", 1 >> "%temp%\OEgetPrivileges.vbs" 
   "%temp%\OEgetPrivileges.vbs" 
   exit /B

   cd /d %~dp0
   %windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil /i "WindowsService1.exe"
   pause
   

9. Create uninstall.bat file (change in pen-ult line /i to /u)
10. To install and start service run install.bat, to stop and uninstall run uninstall.bat

$("input[@name='<%=test2.ClientID%>']:checked");

use this and here ClientID fetch random id created by .net.

I'm using VerboseRunnable class from jcabi-log, which swallows all exceptions and logs them. Very convenient, for example:

import com.jcabi.log.VerboseRunnable;
scheduler.scheduleWithFixedDelay(
  new VerboseRunnable(
    Runnable() {
      public void run() { 
        // the code, which may throw
      }
    },
    true // it means that all exceptions will be swallowed and logged
  ),
  1, 1, TimeUnit.MILLISECONDS
);

Angular will automatically update a component when it detects a variable change .

So all you have to do for it to "refresh" is ensure that the header has a reference to the new data. This could be via a subscription within header.component.ts or via an @Input variable...

an example...

main.html

<app-header [header-data]="headerData"></app-header>

main.component.ts

public headerData:int = 0;

ngOnInit(){
    setInterval(()=>{this.headerData++;}, 250);
}

header.html

<p>{{data}}</p>

header.ts

@Input('header-data') data;

In the above example, the header will recieve the new data every 250ms and thus update the component.

Follow the below steps in Eclipse.

1. Goto -> AVD Manager
2. Create/Edit the AVD.
3. Hardware > New:
4. Configures camera facing back
5. Click on the property value and choose = "webcam0".
6. Once done all the above the webcam should be connected. If it doesnt then you need to check your WebCam drivers.

If you would like to do your filtering in LINQ, you can do it like this:

var ext = new List<string> { "jpg", "gif", "png" };
var myFiles = Directory
    .EnumerateFiles(dir, "*.*", SearchOption.AllDirectories)
    .Where(s => ext.Contains(Path.GetExtension(s).TrimStart(".").ToLowerInvariant()));

Now ext contains a list of allowed extensions; you can add or remove items from it as necessary for flexible filtering.

You should add yourself to the Developer Tools group. The general syntax for adding a user to a group in OS X is as follows:

sudo dscl . append /Groups/<group> GroupMembership <username>

I believe the name for the DevTools group is _developer.

Step: 1 Create Properties declare class

export class Task {
    title: string;
    priority: Array<any>;
    comment: string;

    constructor() {
        this.title      = '';
        this.priority   = [];
        this.comment    = '';
     }
}

Stem: 2 Your Component Class

import { Task } from './task';

export class TaskComponent implements OnInit {
  priorityList: Array<any> = [
    { value: 0, label: '?' },
    { value: 1, label: '?' },
    { value: 2, label: '??' },
    { value: 3, label: '???' },
    { value: 4, label: '????' },
    { value: 5, label: '?????' }
  ];
  taskModel: Task           = new Task();

  constructor(private taskService: TaskService) { }
  ngOnInit() {
    this.taskModel.priority     = [3]; // index number
  }
}

Step: 3 View File .html

<select class="form-control" name="priority" [(ngModel)]="taskModel.priority"  required>
    <option *ngFor="let list of priorityList" [value]="list.value">
      {{list.label}}
    </option>
</select>

  return lambda input: responses[input] if input in responses else default_response

Now:

1. Speed. There is a difference between the two, but speed-wise it should be irrelevant which one you use. echo is marginally faster since it doesn't set a return value if you really want to get down to the nitty gritty.

2. Expression. print() behaves like a function in that you can do: $ret = print "Hello World"; And $ret will be 1. That means that print can be used as part of a more complex expression where echo cannot. An example from the PHP Manual:

$b ? print "true" : print "false";

print is also part of the precedence table which it needs to be if it is to be used within a complex expression. It is just about at the bottom of the precedence list though. Only , AND OR XOR are lower.

3. Parameter(s). The grammar is: echo expression [, expression[, expression] ... ] But echo ( expression, expression ) is not valid. This would be valid: echo ("howdy"),("partner"); the same as: echo "howdy","partner"; (Putting the brackets in that simple example serves no purpose since there is no operator precedence issue with a single term like that.)

So, echo without parentheses can take multiple parameters, which get concatenated:

   echo  "and a ", 1, 2, 3;   // comma-separated without parentheses
   echo ("and a 123");        // just one parameter with parentheses

print() can only take one parameter:

   print ("and a 123");
   print  "and a 123";

You can use the response.text to write to a file:

import requests

files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("resp_text.txt", "w")
file.write(response.text)
file.close()
file = open("resp_content.txt", "w")
file.write(response.text)
file.close()

Set a default value for people with ngInit

<div ng-app>
    <div ng-init="people=1" />
        <input type="radio" ng-model="people" value="1"><label>1</label>
        <input type="radio" ng-model="people" value="2"><label>2</label>
        <input type="radio" ng-model="people" value="3"><label>3</label>
    <ul>
        <li>{{10*people}}€</li>
        <li>{{8*people}}€</li>
        <li>{{30*people}}€</li>
    </ul>
</div>

Demo: Fiddle

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

As for now, they are synonyms.

VARCHAR is reserved by Oracle to support distinction between NULL and empty string in future, as ANSI standard prescribes.

VARCHAR2 does not distinguish between a NULL and empty string, and never will.

If you rely on empty string and NULL being the same thing, you should use VARCHAR2.

Disabled elements don't fire mouse events. Most browsers will propagate an event originating from the disabled element up the DOM tree, so event handlers could be placed on container elements. However, Firefox doesn't exhibit this behaviour, it just does nothing at all when you click on a disabled element.

I can't think of a better solution but, for complete cross browser compatibility, you could place an element in front of the disabled input and catch the click on that element. Here's an example of what I mean:

<div style="display:inline-block; position:relative;">
  <input type="text" disabled />
  <div style="position:absolute; left:0; right:0; top:0; bottom:0;"></div>
</div>?

jq:

$("div > div").click(function (evt) {
    $(this).hide().prev("input[disabled]").prop("disabled", false).focus();
});?

Example: http://jsfiddle.net/RXqAm/170/ (updated to use jQuery 1.7 with prop instead of attr).

Following with Oleg answer, if you want to find ALL objects in a List filtered by a property, you could do something like:

//Search into a generic list ALL items with a generic property
public final class SearchTools {
       public static <T> List<T> findByProperty(Collection<T> col, Predicate<T> filter) {
           List<T> filteredList = (List<T>) col.stream().filter(filter).collect(Collectors.toList());
           return filteredList;
     }

//Search in the list "listItems" ALL items of type "Item" with the specific property "iD_item=itemID"
public static final class ItemTools {
         public static List<Item> findByItemID(Collection<Item> listItems, String itemID) {
             return SearchTools.findByProperty(listItems, item -> itemID.equals(item.getiD_Item()));
         }
     }
}

and similarly if you want to filter ALL items in a HashMap with a certain Property

//Search into a MAP ALL items with a given property
public final class SearchTools {
       public static <T> HashMap<String,T> filterByProperty(HashMap<String,T> completeMap, Predicate<? super Map.Entry<String,T>> filter) {
           HashMap<String,T> filteredList = (HashMap<String,T>) completeMap.entrySet().stream()
                                .filter(filter)
                                .collect(Collectors.toMap(map -> map.getKey(), map -> map.getValue()));
           return filteredList;
     }

     //Search into the MAP ALL items with specific properties
public static final class ItemTools {

        public static HashMap<String,Item> filterByParentID(HashMap<String,Item> mapItems, String parentID) {
            return SearchTools.filterByProperty(mapItems, mapItem -> parentID.equals(mapItem.getValue().getiD_Parent()));
        }

        public static HashMap<String,Item> filterBySciName(HashMap<String,Item> mapItems, String sciName) {
            return SearchTools.filterByProperty(mapItems, mapItem -> sciName.equals(mapItem.getValue().getSciName()));
        }
    }

Use .closest() with a selector:

var $div = $('#divid').closest('div[class^="div-a"]');

There is a very easy work around for this problem.

If you run a 10046 trace on your session (google this... too much to explain). You will see that before any DDL operation Oracle does the following:

LOCK TABLE 'TABLE_NAME' NO WAIT

So if another session has an open transaction you get an error. So the fix is... drum roll please. Issue your own lock before the DDL and leave out the 'NO WAIT'.

Special Note:

if you are doing splitting/dropping partitions oracle just locks the partition. -- so yo can just lock the partition subpartition.

So... The following steps fix the problem.

1. LOCK TABLE 'TABLE NAME'; -- you will 'wait' (developers call this hanging). until the session with the open transaction, commits. This is a queue. so there may be several sessions ahead of you. but you will NOT error out.
2. Execute DDL. Your DDL will then run a lock with the NO WAIT. However, your session has aquired the lock. So you are good.
3. DDL auto-commits. This frees the locks.

DML statements will 'wait' or as developers call it 'hang' while the table is locked.

I use this in code that runs from a job to drop partitions. It works fine. It is in a database that is constantly inserting at a rate of several hundred inserts/second. No errors.

if you are wondering. Doing this in 11g. I have done this in 10g before as well in the past.

One simple approach is to check if unicode is a builtin function. If so, you're in Python 2 and your string will be a string. To ensure everything is in unicode one can do:

import builtins

i = 'cats'
if 'unicode' in dir(builtins):     # True in python 2, False in 3
  i = unicode(i)

If you want to append this css file to header you can do it using mounted() function of the vue file. See the example.
Note: Assume you can access the css file as http://www.yoursite/assets/styles/vendor.css in the browser.

mounted() {
        let style = document.createElement('link');
        style.type = "text/css";
        style.rel = "stylesheet";
        style.href = '/assets/styles/vendor.css';
        document.head.appendChild(style);
    }

In case you expect more than one maximum this will work:

_.maxBy(Object.entries(_.groupBy(x, y => y.length)), y => parseInt(y[0]))[1]

It uses lodash and returns an array.

All the solutions above are looks good and elegant, but the FormData() object does not expect any parameter, but use append() after instantiate it, like what one wrote above:

formData.append(val.name, val.value);

• In HTML 4, <foo / (yes, with no > at all) means <foo> (which leads to <br /> meaning <br>> (i.e. <br>&gt;) and <title/hello/ meaning <title>hello</title>). This is an SGML rule that browsers did a very poor job of supporting, and the spec advises authors to avoid the syntax.

• In XHTML, <foo /> means <foo></foo>. This is an XML rule that applies to all XML documents. That said, XHTML is often served as text/html which (historically at least) gets processed by browsers using a different parser than documents served as application/xhtml+xml. The W3C provides compatibility guidelines to follow for XHTML as text/html. (Essentially: Only use self-closing tag syntax when the element is defined as EMPTY (and the end tag was forbidden in the HTML spec)).

• In HTML5, the meaning of <foo /> depends on the type of element.

  • On HTML elements that are designated as void elements (essentially "An element that existed before HTML5 and which was forbidden to have any content"), end tags are simply forbidden. The slash at the end of the start tag is allowed, but has no meaning. It is just syntactic sugar for people (and syntax highlighters) that are addicted to XML.
  • On other HTML elements, the slash is an error, but error recovery will cause browsers to ignore it and treat the tag as a regular start tag. This will usually end up with a missing end tag causing subsequent elements to be children instead of siblings.
  • Foreign elements (imported from XML applications such as SVG) treat it as self-closing syntax.

Did you forget to join some tables? If not then you probably need to use some aliases.

Change secret_string += str(chr(char + 7429146))

To secret_string += chr(ord(char) + 7429146)

ord() converts the character to its Unicode integer equivalent. chr() then converts this integer into its Unicode character equivalent.

Also, 7429146 is too big of a number, it should be less than 1114111

How about:

String.prototype.strcmp = function(s) {
    if (this < s) return -1;
    if (this > s) return 1;
    return 0;
}

Then, to compare s1 with 2:

s1.strcmp(s2)

It depends on the relation between your components (parent / child) but the best / generic way to make communicate components is to use a shared service.

See this doc for more details:

• https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#bidirectional-service

That being said, you could use the following to provide an instance of the com1 into com2:

<div>
  <com1 #com1>...</com1>
  <com2 [com1ref]="com1">...</com2>
</div>

In com2, you can use the following:

@Component({
  selector:'com2'
})
export class com2{
  @Input()
  com1ref:com1;

  function2(){
    // i want to call function 1 from com1 here
    this.com1ref.function1();
  }
}

Starting with Python 3.4, one can use the glob() method of one of the Path classes in the new pathlib module, which supports ** wildcards. For example:

from pathlib import Path

for file_path in Path('src').glob('**/*.c'):
    print(file_path) # do whatever you need with these files

Update: Starting with Python 3.5, the same syntax is also supported by glob.glob().

Indeed, you should use directives, and there is no event tied to the end of a ng-Repeat loop (as each element is constructed individually, and has it's own event). But a) using directives might be all you need and b) there are a few ng-Repeat specific properties you can use to make your "on ngRepeat finished" event.

Specifically, if all you want is to style/add events to the whole of the table, you can do so using in a directive that encompasses all the ngRepeat elements. On the other hand, if you want to address each element specifically, you can use a directive within the ngRepeat, and it will act on each element, after it is created.

Then, there are the $index, $first, $middle and $last properties you can use to trigger events. So for this HTML:

<div ng-controller="Ctrl" my-main-directive>
  <div ng-repeat="thing in things" my-repeat-directive>
    thing {{thing}}
  </div>
</div>

You can use directives like so:

angular.module('myApp', [])
.directive('myRepeatDirective', function() {
  return function(scope, element, attrs) {
    angular.element(element).css('color','blue');
    if (scope.$last){
      window.alert("im the last!");
    }
  };
})
.directive('myMainDirective', function() {
  return function(scope, element, attrs) {
    angular.element(element).css('border','5px solid red');
  };
});

See it in action in this Plunker. Hope it helps!

I believe that using relative selector + for selecting elements placed immediately after, works here the best (as few suggested before).

It is also possible for this case to use this selector

.home p:first-of-type

but this is element selector not the class one.

Here you have nice list of CSS selectors: https://kolosek.com/css-selectors/

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

`

int array[]=new int[3]; array.length;

so here we have created an array with a memory space of 3... this is how it looks actually

0th 1st 2nd ...........> Index 2 4 5 ...........> Number

So as u see the size of this array is 3 but the index of array is only up to 2 since any array starts with 0th index.

second statement' output shall be 3 since the length of the array is 3... Please don't get confused between the index value and the length of the array....

cheers!

you can also have two classes within an element like this

<div class = "item1 item2 item3"></div>

each item in the class is its own class

.item1 {
  background-color:black;
}

.item2 {
  background-color:green;
}

.item3 {
  background-color:orange;
}

This is what worked for me, sets focus and shows keyboard also

EditText userNameText = (EditText) findViewById(R.id.textViewUserNameText);
userNameText.setFocusable(true);
userNameText.setFocusableInTouchMode(true);
userNameText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(userNameText, InputMethodManager.SHOW_IMPLICIT);

Pass arguments from the command line

// npm install --save-dev gulp gulp-if gulp-uglify minimist

var gulp = require('gulp');
var gulpif = require('gulp-if');
var uglify = require('gulp-uglify');

var minimist = require('minimist');

var knownOptions = {
  string: 'env',
  default: { env: process.env.NODE_ENV || 'production' }
};

var options = minimist(process.argv.slice(2), knownOptions);

gulp.task('scripts', function() {
  return gulp.src('**/*.js')
    .pipe(gulpif(options.env === 'production', uglify())) // only minify in production
    .pipe(gulp.dest('dist'));
});

Then run gulp with:

$ gulp scripts --env development

You can close a figure by calling matplotlib.pyplot.close, for example:

from numpy import *
import matplotlib.pyplot as plt
from scipy import *

t = linspace(0, 0.1,1000)
w = 60*2*pi


fig = plt.figure()
plt.plot(t,cos(w*t))
plt.plot(t,cos(w*t-2*pi/3))
plt.plot(t,cos(w*t-4*pi/3))
plt.show()
plt.close(fig)

You can also close all open figures by calling matplotlib.pyplot.close("all")

use curl --resolve 'yada.com:80:127.0.0.1' http://yada.com/something

What's the difference, you ask?

Among others, this works with HTTPS. Assuming your local server has a certificate for yada.com, the first example above will fail because the yada.com certificate doesn't match the 127.0.0.1 hostname in the URL.

The second example works correctly with HTTPS.

In essence, passing a "Host" header via -H does hack your Host into the header set, but bypasses all of curl's host-specific intelligence. Using --resolve leverages all of the normal logic that applies, but simply pretends the DNS lookup returned the data in your command-line option. It works just like /etc/hosts should.

Note --resolve takes a port number, so for HTTPS you would use

curl --resolve 'yada.com:443:127.0.0.1' https://yada.com/something

This is a very bothersome question, and I feel contributes to many being opposed to Java despite how useful of a language it is.

The fact that you can't trust "System.gc" to do anything is incredibly daunting and can easily invoke "Fear, Uncertainty, Doubt" feel to the language.

In many cases, it is nice to deal with memory spikes that you cause on purpose before an important event occurs, which would cause users to think your program is badly designed/unresponsive.

Having ability to control the garbage collection would be very a great education tool, in turn improving people's understanding how the garbage collection works and how to make programs exploit it's default behavior as well as controlled behavior.

Let me review the arguments of this thread.

1. It is inefficient:

Often, the program may not be doing anything and you know it's not doing anything because of the way it was designed. For instance, it might be doing some kind of long wait with a large wait message box, and at the end it may as well add a call to collect garbage because the time to run it will take a really small fraction of the time of the long wait but will avoid gc from acting up in the middle of a more important operation.

2. It is always a bad practice and indicates broken code.

I disagree, it doesn't matter what garbage collector you have. Its' job is to track garbage and clean it.

By calling the gc during times where usage is less critical, you reduce odds of it running when your life relies on the specific code being run but instead it decides to collect garbage.

Sure, it might not behave the way you want or expect, but when you do want to call it, you know nothing is happening, and user is willing to tolerate slowness/downtime. If the System.gc works, great! If it doesn't, at least you tried. There's simply no down side unless the garbage collector has inherent side effects that do something horribly unexpected to how a garbage collector is suppose to behave if invoked manually, and this by itself causes distrust.

3. It is not a common use case:

It is a use case that cannot be achieved reliably, but could be if the system was designed that way. It's like making a traffic light and making it so that some/all of the traffic lights' buttons don't do anything, it makes you question why the button is there to begin with, javascript doesn't have garbage collection function so we don't scrutinize it as much for it.

4. The spec says that System.gc() is a hint that GC should run and the VM is free to ignore it.

what is a "hint"? what is "ignore"? a computer cannot simply take hints or ignore something, there are strict behavior paths it takes that may be dynamic that are guided by the intent of the system. A proper answer would include what the garbage collector is actually doing, at implementation level, that causes it to not perform collection when you request it. Is the feature simply a nop? Is there some kind of conditions that must me met? What are these conditions?

As it stands, Java's GC often seems like a monster that you just don't trust. You don't know when it's going to come or go, you don't know what it's going to do, how it's going to do it. I can imagine some experts having better idea of how their Garbage Collection works on per-instruction basis, but vast majority simply hopes it "just works", and having to trust an opaque-seeming algorithm to do work for you is frustrating.

There is a big gap between reading about something or being taught something, and actually seeing the implementation of it, the differences across systems, and being able to play with it without having to look at the source code. This creates confidence and feeling of mastery/understanding/control.

To summarize, there is an inherent problem with the answers "this feature might not do anything, and I won't go into details how to tell when it does do something and when it doesn't and why it won't or will, often implying that it is simply against the philosophy to try to do it, even if the intent behind it is reasonable".

It might be okay for Java GC to behave the way it does, or it might not, but to understand it, it is difficult to truly follow in which direction to go to get a comprehensive overview of what you can trust the GC to do and not to do, so it's too easy simply distrust the language, because the purpose of a language is to have controlled behavior up to philosophical extent(it's easy for a programmer, especially novices to fall into existential crisis from certain system/language behaviors) you are capable of tolerating(and if you can't, you just won't use the language until you have to), and more things you can't control for no known reason why you can't control them is inherently harmful.

function Test(){
    this.prop1 = 'prop1';
    this.prop2 = 'prop2';
    this.func1 = function(){
        return this.prop1 + this.prop2;
    }
};

Test.prototype.protoProp1 = 'protoProp1';
Test.prototype.protoProp2 = 'protoProp2';
var newKeywordTest = new Test();
var objectCreateTest = Object.create(Test.prototype);

/* Object.create   */
console.log(objectCreateTest.prop1); // undefined
console.log(objectCreateTest.protoProp1); // protoProp1 
console.log(objectCreateTest.__proto__.protoProp1); // protoProp1

/* new    */
console.log(newKeywordTest.prop1); // prop1
console.log(newKeywordTest.__proto__.protoProp1); // protoProp1

Summary:

1) with new keyword there are two things to note;

a) function is used as a constructor

b) function.prototype object is passed to the __proto__ property ... or where __proto__ is not supported, it is the second place where the new object looks to find properties

2) with Object.create(obj.prototype) you are constructing an object (obj.prototype) and passing it to the intended object ..with the difference that now new object's __proto__ is also pointing to obj.prototype (please ref ans by xj9 for that)

Though there's a correct answer, I share my answer here and hope that this way will more convenience.

WifiManager wifiMan = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInf = wifiMan.getConnectionInfo();
int ipAddress = wifiInf.getIpAddress();
String ip = String.format("%d.%d.%d.%d", (ipAddress & 0xff),(ipAddress >> 8 & 0xff),(ipAddress >> 16 & 0xff),(ipAddress >> 24 & 0xff));

Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.

Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:

/link/mybackend/?field1=value1&field2=value2&field3=value3

and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET.

So your urlconf would be:

url(r'^link/(?P<backend>\w+?)/$', my_function)

and the view would look like:

def my_function(request, backend):
   data = request.GET

and the reverse would be (after importing urllib):

return "%s?%s" % (redirect('my_function', args=(backend,)),
                  urllib.urlencode(form.cleaned_data))

Edited after comment

The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.

If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.

That said, if all you want to do is store the data, then just put it in the session:

request.session['temp_data'] = form.cleaned_data

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

Original answer

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

Late answer but you can also try this when defining your schema.

/**
 * toJSON implementation
 */
schema.options.toJSON = {
    transform: function(doc, ret, options) {
        ret.id = ret._id;
        delete ret._id;
        delete ret.__v;
        return ret;
    }
};

Note that ret is the JSON'ed object, and it's not an instance of the mongoose model. You'll operate on it right on object hashes, without getters/setters.

And then:

Model
    .findById(modelId)
    .exec(function (dbErr, modelDoc){
         if(dbErr) return handleErr(dbErr);

         return res.send(modelDoc.toJSON(), 200);
     });

Edit: Feb 2015

Because I didn't provide a solution to the missing toJSON (or toObject) method(s) I will explain the difference between my usage example and OP's usage example.

OP:

UserModel
    .find({}) // will get all users
    .exec(function(err, users) {
        // supposing that we don't have an error
        // and we had users in our collection,
        // the users variable here is an array
        // of mongoose instances;

        // wrong usage (from OP's example)
        // return res.end(users.toJSON()); // has no method toJSON

        // correct usage
        // to apply the toJSON transformation on instances, you have to
        // iterate through the users array

        var transformedUsers = users.map(function(user) {
            return user.toJSON();
        });

        // finish the request
        res.end(transformedUsers);
    });

My Example:

UserModel
    .findById(someId) // will get a single user
    .exec(function(err, user) {
        // handle the error, if any
        if(err) return handleError(err);

        if(null !== user) {
            // user might be null if no user matched
            // the given id (someId)

            // the toJSON method is available here,
            // since the user variable here is a 
            // mongoose model instance
            return res.end(user.toJSON());
        }
    });

You can use slice() for this:

>> foo = [1,2,3,4,5,6]
=> [1, 2, 3, 4, 5, 6]
>> bar = [10,20,30,40,50,60]
=> [10, 20, 30, 40, 50, 60]
>> half = foo.length / 2
=> 3
>> foobar = foo.slice(0, half) + bar.slice(half, foo.length)
=> [1, 2, 3, 40, 50, 60]

By the way, to the best of my knowledge, Python "lists" are just efficiently implemented dynamically growing arrays. Insertion at the beginning is in O(n), insertion at the end is amortized O(1), random access is O(1).

Just add this below JS file

<script type="text/javascript">
    $(document).ready(function () {
        $('your input's id or class with # or .').datepicker({
            format: "dd/mm/yyyy"
        });
    });
</script>

If you have the file descriptor fstat() returns a stat structure which contain the file size.

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

// fd = fileno(f); //if you have a stream (e.g. from fopen), not a file descriptor.
struct stat buf;
fstat(fd, &buf);
off_t size = buf.st_size;

Use simple FileStream.Read then print it with Convert.ToString(b, 2)

Starting with PHP 8 (2020-11-24), you can use str_contains:

if (str_contains('www.domain.com/car/', 'car')) {
   echo 'car is exist';
} else {
   echo 'no cars';
}

contains method uses equals internally. So you need to override the equals method for your class as per your need.

Btw this does not look syntatically correct:

new Object().setName("John")

A left rotation operation on an array of size n shifts each of the array's elements unit to the left, check this out!!!!!!

public class Solution {
    private static final Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {
        String[] nd = scanner.nextLine().split(" ");

        int n = Integer.parseInt(nd[0]);  //no. of elements in the array

        int d = Integer.parseInt(nd[1]);  //number of left rotations

        int[] a = new int[n]; 

      for(int i=0;i<n;i++){
          a[i]=scanner.nextInt();
      }

        Solution s= new Solution();     
//number of left rotations
        for(int j=0;j<d;j++){
              s.rotate(a,n);
        }
   //print the shifted array  
        for(int i:a){System.out.print(i+" ");}
    }

//shift each elements to the left by one 
   public static void rotate(int a[],int n){
            int  temp=a[0];
        for(int i=0;i<n;i++){
            if(i<n-1){a[i]=a[i+1];}
            else{a[i]=temp;}
      }}
}

This is correct formula to find integers from i to j where i <= R <= j

FLOOR(min+RAND()*(max-min))

There's another solution that I find useful, especially when I want to plot multiple subsets of the same object:

myplot<-ggplot(df)+geom_line(aes(Value1, Value2, group=ID, colour=ID))
myplot %+% subset(df, ID %in% c("P1","P3"))
myplot %+% subset(df, ID %in% c("P2"))

Food for thought: what would a text-to-speech synthesizer do with <center>?

$name = 'file.pdf';
//file_get_contents is standard function
$content = file_get_contents($name);
header('Content-Type: application/pdf');
header('Content-Length: '.strlen( $content ));
header('Content-disposition: inline; filename="' . $name . '"');
header('Cache-Control: public, must-revalidate, max-age=0');
header('Pragma: public');
header('Expires: Sat, 26 Jul 1997 05:00:00 GMT');
header('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT');
echo $content;

This one is similar to @Wilhelm's solution. The loop automates based on a range created by evaluating the populated date column. This was slapped together based strictly on the conversation here and screenshots.

Please note: This assumes that the headers will always be on the same row (row 8). Changing the first row of data (moving the header up/down) will cause the range automation to break unless you edit the range block to take in the header row dynamically. Other assumptions include that VOL and CAPACITY formula column headers are named "Vol" and "Cap" respectively.

Sub Loop3()

Dim dtCnt As Long
Dim rng As Range
Dim frmlas() As String

Application.ScreenUpdating = False

'The following code block sets up the formula output range
dtCnt = Sheets("Loop").Range("A1048576").End(xlUp).Row              'lowest date column populated
endHead = Sheets("Loop").Range("XFD8").End(xlToLeft).Column         'right most header populated
Set rng = Sheets("Loop").Range(Cells(9, 2), Cells(dtCnt, endHead))  'assigns range for automation

ReDim frmlas(1)      'array assigned to formula strings
    'VOL column formula
frmlas(0) = "VOL FORMULA"
    'CAPACITY column formula
frmlas(1) = "CAP FORMULA"

For i = 1 To rng.Columns.count
If rng(0, i).Value = "Vol" Then         'checks for volume formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula= frmlas(0)    'inserts volume formula
    Next j
ElseIf rng(0, i).Value = "Cap" Then     'checks for capacity formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula = frmlas(1)   'inserts capacity formula
    Next j
End If
Next i

Application.ScreenUpdating = True

End Sub

I'll try to give the benchmark of the three most common way (also mentioned above):

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

Assuming WinForms, the ForeColor property allows to change all the text in the TextBox (not just what you're about to add):

TextBox.ForeColor = Color.Red;

To only change the color of certain words, look at RichTextBox.

If javacpl does not open and gives you Could not find the main class:, it could be that Java is confused because of changes in deployment.properties (can be found in C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment on Win7). Delete that file and everything's fine.

This bug seems to be 6 years old, cf. An app should be able to ignore properties that have become obsolete over time, shouldn't it?

One significant difference between INNER JOIN and NATURAL JOIN is the number of columns returned.

Consider:

TableA                           TableB
+------------+----------+        +--------------------+    
|Column1     | Column2  |        |Column1  |  Column3 |
+-----------------------+        +--------------------+
| 1          |  2       |        | 1       |   3      |
+------------+----------+        +---------+----------+

The INNER JOIN of TableA and TableB on Column1 will return

SELECT * FROM TableA AS a INNER JOIN TableB AS b USING (Column1);
SELECT * FROM TableA AS a INNER JOIN TableB AS b ON a.Column1 = b.Column1;

+------------+-----------+---------------------+    
| a.Column1  | a.Column2 | b.Column1| b.Column3|
+------------------------+---------------------+
| 1          |  2        | 1        |   3      |
+------------+-----------+----------+----------+

The NATURAL JOIN of TableA and TableB on Column1 will return:

SELECT * FROM TableA NATURAL JOIN TableB
+------------+----------+----------+    
|Column1     | Column2  | Column3  |
+-----------------------+----------+
| 1          |  2       |   3      |
+------------+----------+----------+

The repeated column is avoided.

(AFAICT from the standard grammar, you can't specify the joining columns in a natural join; the join is strictly name-based. See also Wikipedia.)

(There's a cheat in the inner join output; the a. and b. parts would not be in the column names; you'd just have column1, column2, column1, column3 as the headings.)

The two most usual choices are GTK+, which has documentation links here, and is mostly used with C; or Qt which has documentation here and is more used with C++.

I posted these two as you do not specify an operating system and these two are pretty cross-platform.

For your first question try

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS); 

(available since API 8)

To access individual files in this directory use either File.list() or File.listFiles(). Seems that reporting download progress is only possible in notification, see here.

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

Queue

Queue is a ordered collection of items.

Items are deleted at one end called ‘front’ end of the queue.

Items are inserted at other end called ‘rear’ of the queue.

The first item inserted is the first to be removed (FIFO).

Stack

Stack is a collection of items.

It allows access to only one data item: the last item inserted.

Items are inserted & deleted at one end called ‘Top of the stack’.

It is a dynamic & constantly changing object.

All the data items are put on top of the stack and taken off the top

This structure of accessing is known as Last in First out structure (LIFO)

I think this answer can also work (it may require a little bit of modification though) :

SELECT * FROM Students AS S1 WHERE EXISTS(SELECT Lastname, count(*) FROM Students AS S2 GROUP BY Lastname HAVING COUNT(*) > 3 WHERE S2.Lastname = S1.Lastname)

For SASS/SCSS user using Bourbon, it has a built-in function.

//main.scss
@import 'bourbon';

input {
  width: 300px;

  @include placeholder {
    color: red;
  }
}

CSS Output, you can also grab this portion and paste into your code.

//main.css

input {
  width: 300px;
}

input::-webkit-input-placeholder {
  color: red;
}
input:-moz-placeholder {
  color: red;
}
input::-moz-placeholder {
  color: red;
}
input:-ms-input-placeholder {
  color: red;
}

Try this is working great with me.

A foreach loop in php will iterate over a copy of the original array, making next() and prev() functions useless. If you have an associative array and need to fetch the next item, you could iterate over the array keys instead:

foreach (array_keys($items) as $index => $key) {
    // first, get current item
    $item = $items[$key];
    // now get next item in array
    $next = $items[array_keys($items)[$index + 1]];
}

Since the resulting array of keys has a continuous index itself, you can use that instead to access the original array.

Be aware that $next will be null for the last iteration, since there is no next item after the last. Accessing non existent array keys will throw a php notice. To avoid that, either:

1. Check for the last iteration before assigning values to $next
2. Check if the key with index + 1 exists with array_key_exists()

Using method 2 the complete foreach could look like this:

foreach (array_keys($items) as $index => $key) {
    // first, get current item
    $item = $items[$key];
    // now get next item in array
    $next = null;
    if (array_key_exists($index + 1, array_keys($items))) {
        $next = $items[array_keys($items)[$index + 1]];
    }
}

I get exactly the reported error if ccache is enabled, when using CMake's Xcode generator. Disabling ccache fixed the problem for me. Below I present a fix/check that works for MacOS, but should work similarly on other platforms.

Apparently, it is possible to use CMake's Xcode generator (and others) also in combination with ccache, as is described here. But I never tried it out myself.

# 1) To check if ccache is enabled:
echo $CC
echo $CXX
# This prints something like the following: 
#     ccache clang -Qunused-arguments -fcolor-diagnostics. 
# CC or CXX are typically set in the `.bashrc` or `.zshrc` file.

# 2) To disable ccache, use the following:
CC=clang
CXX=clang++

# 3) Then regenerate the cmake project
cmake -G Xcode <path/to/CMakeLists.txt>

The only way I can think of for short texts like "MENU" is to put every single letter in a span and justify them in a container afterwards. Like this:

<div class="menu-burger">
  <span></span>
  <span></span>
  <span></span>
  <div>
    <span>M</span>
    <span>E</span>
    <span>N</span>
    <span>U</span>
  </div>
</div>

And then the CSS:

.menu-burger {
  width: 50px;
  height: 50px;
  padding: 5px;
}

...

.menu-burger > div {
  display: flex;
  justify-content: space-between;
}

Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...

So the solution was quite simple - I've just done this grant:

grant userB to userA;

That's all folks ;-)

Another requirement is that the object has to be owned by user userA before altering it...

function validateimg(ctrl) {

        var fileUpload = $("#txtPostImg")[0];


        var regex = new RegExp("([a-zA-Z0-9\s_\\.\-:])+(.jpg|.png|.gif)$");
        if (regex.test(fileUpload.value.toLowerCase())) {

            if (typeof (fileUpload.files) != "undefined") {

                var reader = new FileReader();

                reader.readAsDataURL(fileUpload.files[0]);
                reader.onload = function (e) {

                    var image = new Image();

                    image.src = e.target.result;
                    image.onload = function () {

                        var height = this.height;
                        var width = this.width;
                        console.log(this);
                        if ((height >= 1024 || height <= 1100) && (width >= 750 || width <= 800)) {
                            alert("Height and Width must not exceed 1100*800.");
                            return false;
                        }
                        alert("Uploaded image has valid Height and Width.");
                        return true;
                    };
                }
            } else {
                alert("This browser does not support HTML5.");
                return false;

If you have GDAL/OGR compiled with the against the Expat library, you can use the XLSX driver to read .xlsx files, and run SQL expressions from a command prompt. For example, from a osgeo4w shell in the same directory as the spreadsheet, use the ogrinfo utility:

ogrinfo -dialect sqlite -sql "SELECT name, count(*) FROM sheet1 GROUP BY name" Book1.xlsx

will run a SQLite query on sheet1, and output the query result in an unusual form:

INFO: Open of `Book1.xlsx'
      using driver `XLSX' successful.

Layer name: SELECT
Geometry: None
Feature Count: 36
Layer SRS WKT:
(unknown)
name: String (0.0)
count(*): Integer (0.0)
OGRFeature(SELECT):0
  name (String) = Red
  count(*) (Integer) = 849

OGRFeature(SELECT):1
  name (String) = Green
  count(*) (Integer) = 265
...

Or run the same query using ogr2ogr to make a simple CSV file:

$ ogr2ogr -f CSV out.csv -dialect sqlite \
          -sql "SELECT name, count(*) FROM sheet1 GROUP BY name" Book1.xlsx

$ cat out.csv
name,count(*)
Red,849
Green,265
...

To do similar with older .xls files, you would need the XLS driver, built against the FreeXL library, which is not really common (e.g. not from OSGeo4w).

Output:

Basically you do the counts as sub-queries within a standard select.

An example would be the following, this returns 1 row, two columns

SELECT
 (SELECT COUNT(*) FROM MyTable WHERE MyCol = 'MyValue') AS MyTableCount,
 (SELECT COUNT(*) FROM YourTable WHERE MyCol = 'MyValue') AS YourTableCount,

Pure numpy

numpy.loadtxt(open("test.csv", "rb"), delimiter=",", skiprows=1)

Check out the loadtxt documentation.

You can also use python's csv module:

import csv
import numpy
reader = csv.reader(open("test.csv", "rb"), delimiter=",")
x = list(reader)
result = numpy.array(x).astype("float")

You will have to convert it to your favorite numeric type. I guess you can write the whole thing in one line:

result = numpy.array(list(csv.reader(open("test.csv", "rb"), delimiter=","))).astype("float")

Added Hint:

You could also use pandas.io.parsers.read_csv and get the associated numpy array which can be faster.

Well if you want fully transparent than you can use

border: 5px solid transparent;

If you mean opaque/transparent, than you can use

border: 5px solid rgba(255, 255, 255, .5);

Here, a means alpha, which you can scale, 0-1.

Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.

For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.

Demo

Demo 2 (With a background image for nested div)

Demo 3 (With an img tag instead of a background-image)

body {
    background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);   
}

div.wrap {
    border: 5px solid #fff; /* Fall back, not used in fiddle */
    border: 5px solid rgba(255, 255, 255, .5);
    height: 400px;
    width: 400px;
    margin: 50px;
    border-radius: 50%;
}

div.inner {
    background: #fff; /* Fall back, not used in fiddle */
    background: rgba(255, 255, 255, .5);
    height: 380px;
    width: 380px;
    border-radius: 50%; 
    margin: auto; /* Horizontal Center */
    margin-top: 10px; /* Vertical Center ... Yea I know, that's 
                         manually calculated*/
}

Note (For Demo 3): Image will be scaled according to the height and width provided so make sure it doesn't break the scaling ratio.

Passable for getting multiple values with scanf()

int r,m,v,i,e,k;

scanf("%d%d%d%d%d%d",&r,&m,&v,&i,&e,&k);

I had this issue and found a much simpler solution than using a ByteArrayResource.

Simply do

public void loadInvoices(MultipartFile invoices, String channel) throws IOException {

    init();

    Resource invoicesResource = invoices.getResource();

    LinkedMultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
    parts.add("file", invoicesResource);

    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
    httpHeaders.set("channel", channel);

    HttpEntity<LinkedMultiValueMap<String, Object>> httpEntity = new HttpEntity<>(parts, httpHeaders);

    String url = String.format("%s/rest/inbound/invoices/upload", baseUrl);

    restTemplate.postForEntity(url, httpEntity, JobData.class);
}

It works, and no messing around with the file system or byte arrays.

Your code works fine.

def list = [["c":"d"], ["e":"f"], ["g":"h"]]
Map tmpHM = [1:"second (e:f)", 0:"first (c:d)", 2:"third (g:h)"]

for (objKey in tmpHM.keySet()) {   
    HashMap objHM = (HashMap) list.get(objKey);
    print("objHM: ${objHM}  , ")
}

prints objHM: [e:f] , objHM: [c:d] , objHM: [g:h] ,

I had the same problem while working on an installer script. I took a look at what the bin/activate_this.py did and reversed it.

Example:

#! /usr/bin/python
# -*- coding: utf-8 -*-
import os
import sys

# Path to virtualenv
venv_path = os.path.join('/home', 'sixdays', '.virtualenvs', 'test32')

# Save old values
old_os_path = os.environ['PATH']
old_sys_path = list(sys.path)
old_sys_prefix = sys.prefix


def deactivate():
    # Change back by setting values to starting values
    os.environ['PATH'] = old_os_path
    sys.prefix = old_sys_prefix
    sys.path[:0] = old_sys_path


# Activate the virtualenvironment
activate_this = os.path.join(venv_path, 'bin/activate_this.py')
execfile(activate_this, dict(__file__=activate_this))


# Print list of pip packages for virtualenv for example purpose
import pip
print str(pip.get_installed_distributions())

# Unload pip module
del pip

# Deactivate/switch back to initial interpreter
deactivate()

# Print list of initial environment pip packages for example purpose
import pip
print str(pip.get_installed_distributions())

I am not 100% sure if it works as intended. I may have missed something completely.

Decorate functions with different number of arguments:

def frame_tests(fn):
    def wrapper(*args):
        print "\nStart: %s" %(fn.__name__)
        fn(*args)
        print "End: %s\n" %(fn.__name__)
    return wrapper

@frame_tests
def test_fn1():
    print "This is only a test!"

@frame_tests
def test_fn2(s1):
    print "This is only a test! %s" %(s1)

@frame_tests
def test_fn3(s1, s2):
    print "This is only a test! %s %s" %(s1, s2)

if __name__ == "__main__":
    test_fn1()
    test_fn2('OK!')
    test_fn3('OK!', 'Just a test!')

Result:

Start: test_fn1  
This is only a test!  
End: test_fn1  
  
  
Start: test_fn2  
This is only a test! OK!  
End: test_fn2  
  
  
Start: test_fn3  
This is only a test! OK! Just a test!  
End: test_fn3  

The environment variables displayed in Jenkins (Manage Jenkins -> System information) are inherited from the system (i.e. inherited environment variables)

If you run env command in a shell you should see the same environment variables as Jenkins shows.

These variables are either set by the shell/system or by you in ~/.bashrc, ~/.bash_profile.

There are also environment variables set by Jenkins when a job executes, but these are not displayed in the System Information.

Here's what I've found to work:

f_rd = open(path, 'r')
file_lines = f_rd.readlines()
f_rd.close()

matches = [line for line in file_lines if "chars of Interest" in line]
index = file_lines.index(matches[0])

If your variable is an argument, you can simply use %~dpn (for paths) or %~n (for names only) followed by the argument number, so you don't have to worry for varying extension lengths.

For instance %~dpn0 will return the path of the batch file without its extension, %~dpn1 will be %1 without extension, etc.

Whereas %~n0 will return the name of the batch file without its extension, %~n1 will be %1 without path and extension, etc.

Maybe you should better use a case for such lists:

case "$cms" in
  wordpress|meganto|typo3)
    do_your_else_case
    ;;
  *)
    do_your_then_case
    ;;
esac

I think for long such lists this is better readable.

If you still prefer the if you can do it with single brackets in two ways:

if [ "$cms" != wordpress -a "$cms" != meganto -a "$cms" != typo3 ]; then

or

if [ "$cms" != wordpress ] && [ "$cms" != meganto ] && [ "$cms" != typo3 ]; then

In my case the issue was due to how I build my Nav bar. I was doing it through a jQuery plugin so I can quickly build Bootstrap components through javascript.

To cut a long story short binding the data elements of the button through jQuery .data() resulted in a collapse button that didn't work, doing it via .attr() fixed the issue.

This doesn't work:

$this.addClass("navbar navbar-default")
  .append($("<div />").addClass("container-fluid")
    .append($("<div />").addClass("navbar-header")
      .append($("<button />").addClass("navbar-toggle collapsed")
        .attr("type","button")
        .attr("aria-expanded", "false")
        .data("target","#" + id)
        .data("toggle","collapse")
        .html("<span class='sr-only'>Toggle navigation</span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"))
        .append($("<a href='#' />").addClass("navbar-brand")
          .append(document.createTextNode(settings.label))))
    .append($("<div />").addClass("collapse navbar-collapse").attr("id",id)));

But this does (with the changes left in comments):

$this.addClass("navbar navbar-default")
  .append($("<div />").addClass("container-fluid")
    .append($("<div />").addClass("navbar-header")
      .append($("<button />").addClass("navbar-toggle collapsed")
        .attr("type","button")
        .attr("aria-expanded", "false")
        .attr("data-target", "#" + id) //.data("target","#" + id)
        .attr("data-toggle", "collapse") // .data("toggle","collapse")
        .html("<span class='sr-only'>Toggle navigation</span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"))
        .append($("<a href='#' />").addClass("navbar-brand")
          .append(document.createTextNode(settings.label))))
    .append($("<div />").addClass("collapse navbar-collapse").attr("id",id)));

I can only assume that this is related to the way jQuery binds .data(), it doesn't write the attributes out to the elements, but just attaches them to the jQuery object. Using the .data() version resulted in HTML:

<button class="navbar-toggle collapsed" aria-expanded="false" type="button" >

Where as the .attr() version gives:

<button class="navbar-toggle collapsed" aria-expanded="false" type="button" data-toggle="collapse" data-target="#6a2034fe-8922-4edd-920e-6bd0ea0b2caf">

It seems that Bootstrap needs the data-nnn attribute in the HTML.

You should probably start with a little theory and simple examples such as the midpoint displacement algorithm. You should also learn a little about Perlin Noise if you are interested in generating graphics. I used this to get me started with my final year project on procedural generation.

Fractals are closely related to procedural generation.

Terragen and SpeedTree will show you some amazing possibilities of procedural generation.

Procedural generation is a technique that can be used in any language (it is definitely not restricted to procedural languages such as C, as it can be used in OO languages such as Java, and Logic languages such as Prolog). A good understanding of recursion in any language will strengthen your grasp of Procedural Generation.

As for 'serious' or non-game code, procedural generation techniques have been used to:

• simulate the growth of cities in order to plan for traffic management
• to simulate the growth of blood vessels
• SpeedTree is used in movies and architectural presentations

To change action value of form dynamically, you can try below code:

below code is if you are opening some dailog box and inside that dailog box you have form and you want to change the action of it. I used Bootstrap dailog box and on opening of that dailog box I am assigning action value to the form.

$('#your-dailog-id').on('show.bs.modal', function (event) {
    var link = $(event.relatedTarget);// Link that triggered the modal
    var cURL= link.data('url');// Extract info from data-* attributes
    $("#delUserform").attr("action", cURL);
});

If you are trying to change the form action on regular page, use below code

$("#yourElementId").change(function() { 
  var action = <generate_action>;
  $("#formId").attr("action", action);
});

In the below investigation as API, I use http://example.com instead of http://myApiUrl/login from your question, because this first one working.

I assume that your page is on http://my-site.local:8088.

The reason why you see different results is that Postman:

• set header Host=example.com (your API)
• NOT set header Origin

This is similar to browsers' way of sending requests when the site and API has the same domain (browsers also set the header item Referer=http://my-site.local:8088, however I don't see it in Postman). When Origin header is not set, usually servers allow such requests by default.

This is the standard way how Postman sends requests. But a browser sends requests differently when your site and API have different domains, and then CORS occurs and the browser automatically:

• sets header Host=example.com (yours as API)
• sets header Origin=http://my-site.local:8088 (your site)

(The header Referer has the same value as Origin). And now in Chrome's Console & Networks tab you will see:

When you have Host != Origin this is CORS, and when the server detects such a request, it usually blocks it by default.

Origin=null is set when you open HTML content from a local directory, and it sends a request. The same situation is when you send a request inside an <iframe>, like in the below snippet (but here the Host header is not set at all) - in general, everywhere the HTML specification says opaque origin, you can translate that to Origin=null. More information about this you can find here.

fetch('http://example.com/api', {method: 'POST'});

Look on chrome-console > network tab

If you do not use a simple CORS request, usually the browser automatically also sends an OPTIONS request before sending the main request - more information is here. The snippet below shows it:

fetch('http://example.com/api', {_x000D_
  method: 'POST',_x000D_
  headers: { 'Content-Type': 'application/json'}_x000D_
});

Look in chrome-console -> network tab to 'api' request._x000D_
This is the OPTIONS request (the server does not allow sending a POST request)

You can change the configuration of your server to allow CORS requests.

Here is an example configuration which turns on CORS on nginx (nginx.conf file) - be very careful with setting always/"$http_origin" for nginx and "*" for Apache - this will unblock CORS from any domain.

location ~ ^/index\.php(/|$) {_x000D_
   ..._x000D_
    add_header 'Access-Control-Allow-Origin' "$http_origin" always;_x000D_
    add_header 'Access-Control-Allow-Credentials' 'true' always;_x000D_
    if ($request_method = OPTIONS) {_x000D_
        add_header 'Access-Control-Allow-Origin' "$http_origin"; # DO NOT remove THIS LINES (doubled with outside 'if' above)_x000D_
        add_header 'Access-Control-Allow-Credentials' 'true';_x000D_
        add_header 'Access-Control-Max-Age' 1728000; # cache preflight value for 20 days_x000D_
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';_x000D_
        add_header 'Access-Control-Allow-Headers' 'My-First-Header,My-Second-Header,Authorization,Content-Type,Accept,Origin';_x000D_
        add_header 'Content-Length' 0;_x000D_
        add_header 'Content-Type' 'text/plain charset=UTF-8';_x000D_
        return 204;_x000D_
    }_x000D_
}

Here is an example configuration which turns on CORS on Apache (.htaccess file)

Header always set Access-Control-Allow-Headers "My-First-Header,My-Second-Header,Authorization, content-type, csrf-token"

You can also use array_reduce() if you prefer a more functional approach

For instance:

$userNames = array_reduce($users, function ($carry, $user) {
    array_push($carry, $user['name']);
    return $carry;
}, []);

Or if you like to be fancy,

$userNames = [];
array_map(function ($user) use (&$userNames){
    $userNames[]=$user['name'];
}, $users);

This and all the methods above do loop behind the scenes though ;)

I don't know how you've setup MySQL on your Linux environment but have you checked?

There is no way to avoid inconsistent rounding for prices with x.xx5 as actual value using either multiplication or division. If you need to calculate correct prices client-side you should keep all amounts in cents. This is due to the nature of the internal representation of numeric values in JavaScript. Notice that Excel suffers from the same problems so most people wouldn't notice the small errors caused by this phenomen. However errors may accumulate whenever you add up a lot of calculated values, there is a whole theory around this involving the order of calculations and other methods to minimize the error in the final result. To emphasize on the problems with decimal values, please note that 0.1 + 0.2 is not exactly equal to 0.3 in JavaScript, while 1 + 2 is equal to 3.

I had countless issues doing this but finally came up with a solution that works.

Basically the code below is adding a click handler to the video but ignoring all the clicks on the lower part (0.82 is arbitrary but seems to work on all sizes).

    $("video").click(function(e){

        // get click position 
        var clickY = (e.pageY - $(this).offset().top);
        var height = parseFloat( $(this).height() );

        // avoids interference with controls
        if(y > 0.82*height) return;

        // toggles play / pause
        this.paused ? this.play() : this.pause();

    });

In JS, "+" concatenation works by creating a new String object.

For example, with...

var s = "Hello";

...we have one object s.

Next:

s = s + " World";

Now, s is a new object.

2nd method: String.prototype.concat

While I agree with Jörn's answer if your class conforms to the JavaBeabs spec, here is a good alternative if it doesn't and you use Spring.

Spring has a class named ReflectionUtils that offers some very powerful functionality, including doWithFields(class, callback), a visitor-style method that lets you iterate over a classes fields using a callback object like this:

public void analyze(Object obj){
    ReflectionUtils.doWithFields(obj.getClass(), field -> {

        System.out.println("Field name: " + field.getName());
        field.setAccessible(true);
        System.out.println("Field value: "+ field.get(obj));

    });
}

But here's a warning: the class is labeled as "for internal use only", which is a pity if you ask me

Here was my solution:

In the constructors add these two lines:

this.BackColor = Color.LimeGreen;
this.TransparencyKey = Color.LimeGreen;

In your form, add this method:

protected override void OnPaintBackground(PaintEventArgs e)
{
    e.Graphics.FillRectangle(Brushes.LimeGreen, e.ClipRectangle);
}

Be warned, not only is this form fully transparent inside the frame, but you can also click through it. However, it might be cool to draw an image onto it and make the form able to be dragged everywhere to create a custom shaped form.

You could just change the shebang line. I do this all the time on new systems.

If you want pip to install to a current version of Python installed just update the shebang line to the correct version of pythons path.

For example, to change pip (not pip3) to install to Python 3:

#!/usr/bin/python

To:

#!/usr/bin/python3

Any module you install using pip should install to Python not Python.

Or you could just change the path.

I try with this, no modifications on the css.

I think the answer to this question pretty much sums up the problem with your question.

If what you want to do is find out whether a given host will accept TCP connections on port 80, you can do this:

$host = '193.33.186.70'; 
$port = 80; 
$waitTimeoutInSeconds = 1; 
if($fp = fsockopen($host,$port,$errCode,$errStr,$waitTimeoutInSeconds)){   
   // It worked 
} else {
   // It didn't work 
} 
fclose($fp);

For anything other than TCP it will be more difficult (although since you specify 80, I guess you are looking for an active HTTP server, so TCP is what you want). TCP is sequenced and acknowledged, so you will implicitly receive a returned packet when a connection is successfully made. Most other transport protocols (commonly UDP, but others as well) do not behave in this manner, and datagrams will not be acknowledged unless the overlayed Application Layer protocol implements it.

The fact that you are asking this question in this manner tells me you have a fundamental gap in your knowledge on Transport Layer protocols. You should read up on ICMP and TCP, as well as the OSI Model.

Also, here's a slightly cleaner version to ping to hosts.

// Function to check response time
function pingDomain($domain){
    $starttime = microtime(true);
    $file      = fsockopen ($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

    if (!$file) $status = -1;  // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}

Even after adding -DPYTHON_INCLUDE_DIR and -DPYTHON_LIBRARY as suggested above, I was still facing the error Could NOT find PythonInterp. What solved it was adding -DPYTHON_EXECUTABLE:FILEPATH= to cmake as suggested in https://github.com/pybind/pybind11/issues/99#issuecomment-182071479:

To have deselect (DidDeselectRowAt) fire when clicked the first time because of preloaded data; you need inform the tableView that the row is already selected to begin with, so that an initial click then deselects the row:

//Swift 3:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    if tableView[indexPath.row] == "data value"

        tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none)

    }
}

Generate a github oauth token here and export your github token as an environment variable:

export GITHUB_TOKEN=123

Set git config to use the basic auth url:

git config --global url."https://$GITHUB_TOKEN:[email protected]/".insteadOf "https://github.com/"

Now you can go get your private repo.

I know it's a little off-topic, but following up with the solution presented by Jonas Bøhmer, actually I think that MOD is the best solution to your example.

If your intention was to limit the result to one digit, MOD is the best approach to achieve it.

ie. Let's suppose that VLOOKUP(A1, B:B, 1, 0) returns 23. Your IF formula would simply make this calculation: 23 - 10 and return 13 as the result.

On the other hand, MOD(VLOOKUP(A1, B:B, 1, 0), 10) would divide 23 by 10 and show the remainder: 3.

Back to the main topic, when I need to use a formula that repeats some part, I usually put it on another cell and then hide it as some people already suggested.

The problem with Yossi Shasho's Code is that the page is scrolling to the top every 50 ms. So I have modified that code. Now its working fine on all modern browsers, IE8 and above

var storedHash = window.location.hash;
function changeHashOnLoad() {
    window.location.href += "#";
    setTimeout("changeHashAgain()", "50");
}

function changeHashAgain() {
    window.location.href += "1";
}

function restoreHash() {
    if (window.location.hash != storedHash) {
        window.location.hash = storedHash;
    }
}

if (window.addEventListener) {
    window.addEventListener("hashchange", function () {
        restoreHash();
    }, false);
}
else if (window.attachEvent) {
    window.attachEvent("onhashchange", function () {
        restoreHash();
    });
}
$(window).load(function () { changeHashOnLoad(); });

You are trying to to an Insert (with ExecuteNonQuery()) on a SQL connection that is used by this reader already:

while (myReader.Read())

Either read all the values in a list first, close the reader and then do the insert, or use a new SQL connection.

It is usually a good idea to declare variables as unsigned or size_t if they will be compared to sizes, to avoid this issue. Whenever possible, use the exact type you will be comparing against (for example, use std::string::size_type when comparing with a std::string's length).

Compilers give warnings about comparing signed and unsigned types because the ranges of signed and unsigned ints are different, and when they are compared to one another, the results can be surprising. If you have to make such a comparison, you should explicitly convert one of the values to a type compatible with the other, perhaps after checking to ensure that the conversion is valid. For example:

unsigned u = GetSomeUnsignedValue();
int i = GetSomeSignedValue();

if (i >= 0)
{
    // i is nonnegative, so it is safe to cast to unsigned value
    if ((unsigned)i >= u)
        iIsGreaterThanOrEqualToU();
    else
        iIsLessThanU();
}
else
{
    iIsNegative();
}

Linux, Walkthrough to find a class file among many jars.

Go to the directory that contains the jars underneath.

eric@dev /home/el/kafka_2.10-0.8.1.1/libs $ ls
blah.txt                             metrics-core-2.2.0.jar
jopt-simple-3.2.jar                  scala-library-2.10.1.jar
kafka_2.10-0.8.1.1-sources.jar       zkclient-0.3.jar
kafka_2.10-0.8.1.1-sources.jar.asc   zookeeper-3.3.4.jar
log4j-1.2.15.jar

I'm looking for which jar provides for the Producer class.

Understand how the for loop works:

eric@dev /home/el/kafka_2.10-0.8.1.1/libs $ for i in `seq 1 3`; do
> echo $i
> done
1
2
3

Understand why find this works:

eric@dev /home/el/kafka_2.10-0.8.1.1/libs $ find . -name "*.jar"
./slf4j-api-1.7.2.jar
./zookeeper-3.3.4.jar
./kafka_2.10-0.8.1.1-javadoc.jar
./slf4j-1.7.7/osgi-over-slf4j-1.7.7-sources.jar

You can pump all the jars underneath into the for loop:

eric@dev /home/el/kafka_2.10-0.8.1.1/libs $ for i in `find . -name "*.jar"`; do
> echo $i
> done

./slf4j-api-1.7.2.jar
./zookeeper-3.3.4.jar
./kafka_2.10-0.8.1.1-javadoc.jar
./kafka_2.10-0.8.1.1-sources.jar

Now we can operate on each one:

Do a jar tf on every jar and cram it into blah.txt:

for i in `find . -name "*.jar"`; do echo $i; jar tf $i; done > blah.txt

Inspect blah.txt, it's a list of all the classes in all the jars. You can search that file for the class you want, then look for the jar that came before it, that's the one you want.

This is a universal wrapper for hover written in typescript. The component will apply style passed via props 'hoverStyle' on hover event.

import React, { useState } from 'react';

export const Hover: React.FC<{
  style?: React.CSSProperties;
  hoverStyle: React.CSSProperties;
}> = ({ style = {}, hoverStyle, children }) => {
  const [isHovered, setHovered] = useState(false);
  const calculatedStyle = { ...style, ...(isHovered ? hoverStyle : {}) };
  return (
    <div
      style={calculatedStyle}
      onMouseEnter={() => setHovered(true)}
      onMouseLeave={() => setHovered(false)}
    >
      {children}
    </div>
  );
};    

<?php
ini_set('xdebug.max_nesting_level', 9999);
... your code ...

P.S. Change 9999 to any number you want.

you can use those functions together with iferror as a work around.

try =IFERROR(VALUE(A4),(CONCATENATE(A4)))

The problem in my case was missing component declaration in the module, but even after adding the declaration the error persisted. I had stop the server and rebuild the entire project in VS Code for the error to go away.

If you came across this error while using the command line its because you must be using php 7 to execute whatever it is you are trying to execute. What happened is that the code is trying to use an operator thats only available in php7+ and is causing a syntax error.

If you already have php 7+ on your computer try pointing the command line to the higher version of php you want to use.

export PATH=/usr/local/[php-7-folder]/bin/:$PATH

Here is the exact location that worked based off of my setup for reference:

export PATH=/usr/local/php5-7.1.4-20170506-100436/bin/:$PATH

The operator thats actually caused the break is the "null coalesce operator" you can read more about it here:

php7 New Operators

I had the same problem and the following block of code was giving the same error message:

repositories.forEach( repo => {
        const commits = await getCommits(repo);
        displayCommit(commits);
});

The problem is that the method getCommits() was async but I was passing it the argument repo which was also produced by a Promise. So, I had to add the word async to it like this: async(repo) and it started working:

repositories.forEach( async(repo) => {
        const commits = await getCommits(repo);
        displayCommit(commits);
});

Simply add these parameters : In the header option of the request, add Content-Type:application/json

and in the body, select Raw format and put your json params like {'guid':'61791957-81A3-4264-8F32-49BCFB4544D8'}

I've found the solution on http://www.iminfo.in/post/post-json-postman-rest-client-chrome

Here is another solution for adding class definitions to the widgets after declaring the fields in the class.

def __init__(self, *args, **kwargs):
    super(SampleClass, self).__init__(*args, **kwargs)
    self.fields['name'].widget.attrs['class'] = 'my_class'

Using make_axes is even easier and gives a better result. It also provides possibilities to customise the positioning of the colorbar. Also note the option of subplots to share x and y axes.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

fig, axes = plt.subplots(nrows=2, ncols=2, sharex=True, sharey=True)
for ax in axes.flat:
    im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)

cax,kw = mpl.colorbar.make_axes([ax for ax in axes.flat])
plt.colorbar(im, cax=cax, **kw)

plt.show()

     //controller  You can use this way

    public ActionResult Index()
    {
      List<Fund> fundList = db.Funds.ToList();
     ViewBag.Funds = fundList;
        return View();
    }




<--View ; You can use this way html-->

@foreach (var item in (List<Fund>)ViewBag.Funds)
{
    <p>@item.firtname</p>
}

If you provide your JVM the Spring profile there should be no problems:

java -Dspring.profiles.active=development -jar yourApplication.jar 

Also see Spring-Documentation:

http://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html

69.5 Set the active Spring profiles

The Spring Environment has an API for this, but normally you would set a System property (spring.profiles.active) or an OS environment variable (SPRING_PROFILES_ACTIVE). E.g. launch your application with a -D argument (remember to put it before the main class or jar archive):

$ java -jar -Dspring.profiles.active=production demo-0.0.1-SNAPSHOT.jar

In Spring Boot you can also set the active profile in application.properties, e.g.

spring.profiles.active=production

A value set this way is replaced by the System property or environment variable setting, but not by the SpringApplicationBuilder.profiles() method. Thus the latter Java API can be used to augment the profiles without changing the defaults.

See Chapter 25, Profiles in the ‘Spring Boot features’ section for more information.

The 00947 message indicates that the record which you are trying to send to Oracle lacks one or more of the columns which was included at the time the table was created. The 00913 message indicates that the record which you are trying to send to Oracle includes more columns than were included at the time the table was created. You just need to check the number of columns and its type in both the tables ie the tables that are involved in the sql.

Platform NetBeans 7.3, Apache Tomcat 7.0.34 re: Tomcat Manager

I spent 3 days tracking this down because I thought I had a bad install.

On Windows and Linux, NetBeans uses a separate file location for CATALINA_BASE:

http://wiki.netbeans.org/FaqInstallationDefaultTomcatPassword

So you can modify the tomcat_user.xml under CATALINA_HOME: until your face turns blue, to no effect.

It appears that the IDE only requires, manager-script,admin roles under CATALINA_BASE:.

When I tried to add a user to the manager-gui role (to the correct tomcat_user.xml file), required for access to the Tomcat Manager, Tomcat stopped presenting the login dialog and went directly to the 401 access denied splash page.

It appears that the NetBeans package uses a locked-down version of TomCat.

I hope this saves everyone some time.

Windows 10 - TH2 and above:

(a.k.a. Version 1511, build 10586, release 2015-11-10)

At Command Prompt:

echo ^[[32m HI ^[[0m

Using the actual keys:   echo Ctrl+[[32m HI Ctrl+[[0mEnter

You should see a green "HI" below it.

Code numbers can be found here:

• https://en.wikipedia.org/wiki/ANSI_escape_code#Colors

Notepad:

To save this into notepad, you can type ESC into it using: Alt+027 with the numpad, then the [32m part. Another trick when I was on a laptop, redirect the line above into a file to get started, then cut and paste:

echo echo ^[[32m HI ^[[0m >> batch_file.cmd

You'll need to install numpy, scipy and matplotlib to get pylab. In ubuntu you can install them with this command:

sudo apt-get install python-numpy python-scipy python-matplotlib

If you installed python from source you will need to install these packages through pip. Note that you may have to install other dependencies to do this, as well as install numpy before the other two.

That said, I would recommend using the version of python in the repositories as I think it is up to date with the current version of python (2.7.3).

If you can use jQuery, look at load. You could then set your function to run after your element finishes loading.

For example, consider a page with a simple image:

<img src="book.png" alt="Book" id="book" />

The event handler can be bound to the image:

$('#book').load(function() {
  // Handler for .load() called.
});

If you need all elements on the current window to load, you can use

$(window).load(function () {
  // run code
});

If you cannot use jQuery, the plain Javascript code is essentially the same amount of (if not less) code:

window.onload = function() {
  // run code
};

Try this in Swift :

var urlString = myUrl.absoluteString

Objective-C:

NSString *urlString = [myURL absoluteString];

You could also group functions in one main file together with the main function looking like this:

function [varargout] = main( subfun, varargin )
[varargout{1:nargout}] = feval( subfun, varargin{:} ); 

% paste your subfunctions below ....
function str=subfun1
str='hello'

Then calling subfun1 would look like this: str=main('subfun1')

This merge approach will add one commit on top of master which pastes in whatever is in feature, without complaining about conflicts or other crap.

Before you touch anything

git stash
git status # if anything shows up here, move it to your desktop

Now prepare master

git checkout master
git pull # if there is a problem in this step, it is outside the scope of this answer

Get feature all dressed up

git checkout feature
git merge --strategy=ours master

Go for the kill

git checkout master
git merge --no-ff feature

It is the difference between greedy and non-greedy quantifiers.

Consider the input 101000000000100.

Using 1.*1, * is greedy - it will match all the way to the end, and then backtrack until it can match 1, leaving you with 1010000000001.
.*? is non-greedy. * will match nothing, but then will try to match extra characters until it matches 1, eventually matching 101.

All quantifiers have a non-greedy mode: .*?, .+?, .{2,6}?, and even .??.

In your case, a similar pattern could be <([^>]*)> - matching anything but a greater-than sign (strictly speaking, it matches zero or more characters other than > in-between < and >).

See Quantifier Cheat Sheet.

In python, when you have an iterable, usually you iterate without an index:

letters = 'abcdef' # or a list, tupple or other iterable
for l in letters:
    print(l)

If you need to traverse the iterable in reverse order, you would do:

for l in letters[::-1]:
    print(l)

When for any reason you need the index, you can use enumerate:

for i, l in enumerate(letters, start=1): #start is 0 by default
    print(i,l)

You can enumerate in reverse order too...

for i, l in enumerate(letters[::-1])
    print(i,l)

ON ANOTHER NOTE...

Usually when we traverse an iterable we do it to apply the same procedure or function to each element. In these cases, it is better to use map:

If we need to capitilize each letter:

map(str.upper, letters)

Or get the Unicode code of each letter:

map(ord, letters)

This worked for me:

import re
thestring = "text1\ntext2\nhttp://url.com/bla1/blah1/\ntext3\ntext4\nhttp://url.com/bla2/blah2/\ntext5\ntext6"

URLless_string = re.sub(r'\w+:\/{2}[\d\w-]+(\.[\d\w-]+)*(?:(?:\/[^\s/]*))*', '', thestring)
print URLless_string

Result:

text1
text2

text3
text4

text5
text6

This is a big topic. The Spring reference doc devotes multiple chapters to it. I recommend reading the ones on Aspect-Oriented Programming and Transactions, as Spring's declarative transaction support uses AOP at its foundation.

But at a very high level, Spring creates proxies for classes that declare @Transactional on the class itself or on members. The proxy is mostly invisible at runtime. It provides a way for Spring to inject behaviors before, after, or around method calls into the object being proxied. Transaction management is just one example of the behaviors that can be hooked in. Security checks are another. And you can provide your own, too, for things like logging. So when you annotate a method with @Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you're annotating. And when clients make calls into your object, the calls are intercepted and the behaviors injected via the proxy mechanism.

Transactions in EJB work similarly, by the way.

As you observed, through, the proxy mechanism only works when calls come in from some external object. When you make an internal call within the object, you're really making a call through the "this" reference, which bypasses the proxy. There are ways of working around that problem, however. I explain one approach in this forum post in which I use a BeanFactoryPostProcessor to inject an instance of the proxy into "self-referencing" classes at runtime. I save this reference to a member variable called "me". Then if I need to make internal calls that require a change in the transaction status of the thread, I direct the call through the proxy (e.g. "me.someMethod()".) The forum post explains in more detail. Note that the BeanFactoryPostProcessor code would be a little different now, as it was written back in the Spring 1.x timeframe. But hopefully it gives you an idea. I have an updated version that I could probably make available.

Surely you just need:

double seconds = milliseconds / 1000.0;

There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0 (as a double literal) forces. (I'm assuming your milliseconds value is an integer of some form.)

Note that as usual with double, you may not be able to represent the result exactly. Consider using BigDecimal if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double is probably appropriate, but...)

You can just pass it

def my_function(my_data):
    my_data["schoolname"] = "something"
    print my_data

or if you really want to

def my_function(**kwargs):
    kwargs["schoolname"] = "something"
    print kwargs

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

If you want to write the history to a file:

import readline
readline.write_history_file('python_history.txt')

The help function gives:

Help on built-in function write_history_file in module readline:

    The default filename is ~/.history.

Handles either type of line break

str.replace(new RegExp('\r?\n','g'), '<br />');

I had \bin as part of the path. Up one level of the selected directory worked for me.

This is the simplest way:

if(str.Contains("hello"))

If the accepted https://stackoverflow.com/a/33733454/8520387 doesn't work for you, then disable other enabled Ethernet Cards. After this try to run your vagrant script again and it will create a new Network Card for you. For me it was #3

Check out this article. I believe it should help you get what you are wanting. If your table already exists, and it has data in it already, the error you are getting may be due to the auto_increment trying to assign a value that already exists for other records.

In short, as others have already mentioned in comments, sequences, as they are thought of and handled in Oracle, do not exist in MySQL. However, you can likely use auto_increment to accomplish what you want.

Without additional details on the specific error, it is difficult to provide more specific help.

UPDATE

CREATE TABLE ORD (
  ORDID INT NOT NULL AUTO_INCREMENT,
  //Rest of table code
  PRIMARY KEY (ordid)
)
AUTO_INCREMENT = 622;

This link is also helpful for describing usage of auto_increment. Setting the AUTO_INCREMENT value appears to be a table option, and not something that is specified as a column attribute specifically.

Also, per one of the links from above, you can alternatively set the auto increment start value via an alter to your table.

ALTER TABLE ORD AUTO_INCREMENT = 622;

UPDATE 2 Here is a link to a working sqlfiddle example, using auto increment.
I hope this info helps.

You have to give a name attribute on your <select /> element, and then use it from the $_POST or $_GET (depending on how you transmit data) arrays in PHP. Be sure to sanitize user input, though.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

You can also install Fiddler (http://www.fiddler2.com/fiddler2/) which is very easy to install (easier than Apache for example).

After launching it, it will register itself as system proxy. Then open the "Rules" menu, and choose "Customize Rules..." to open a JScript file which allow you to customize requests.

To add a custom header, just add a line in the OnBeforeRequest function:

oSession.oRequest.headers.Add("MyHeader", "MyValue");
