If above solutions not work just one time comment the getter and setter methods of entity class and do not set the value of id.(Primary key) Then this will work.

You may have come here for advice on when to use persist and when to use merge. I think that it depends the situation: how likely is it that you need to create a new record and how hard is it to retrieve persisted data.

Let's presume you can use a natural key/identifier.

• Data needs to be persisted, but once in a while a record exists and an update is called for. In this case you could try a persist and if it throws an EntityExistsException, you look it up and combine the data:

  try { entityManager.persist(entity) }

  catch(EntityExistsException exception) { /* retrieve and merge */ }

• Persisted data needs to be updated, but once in a while there is no record for the data yet. In this case you look it up, and do a persist if the entity is missing:

  entity = entityManager.find(key);

  if (entity == null) { entityManager.persist(entity); }

  else { /* merge */ }

If you don't have natural key/identifier, you'll have a harder time to figure out whether the entity exist or not, or how to look it up.

The merges can be dealt with in two ways, too:

1. If the changes are usually small, apply them to the managed entity.
2. If changes are common, copy the ID from the persisted entity, as well as unaltered data. Then call EntityManager::merge() to replace the old content.

Going forward, for graphical elements that are purely decorative, the best solution is to use:

android:importantForAccessibility="no"

This makes sense if your min SDK version is at least 16, since devices running lower versions will ignore this attribute.

If you're stuck supporting older versions, you should use (like others pointed out already):

android:contentDescription="@null"

You are not creating datetime index properly,

format = '%Y-%m-%d %H:%M:%S'
df['Datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'], format=format)
df = df.set_index(pd.DatetimeIndex(df['Datetime']))

false != 'false'

For good measures, put the result of validate into a variable to avoid double validation and use that in the IF statement. Like this:

var result = ValidateForm();
if(result == false) {
...
}

You cannot use simple jquery's Animate to do that as it involves 2 values.

To solve it just include Background Position Plugin and you can animate Backgrounds at will.

Go to Environment variable and add

JAVA_HOME=C:\Program Files (x86)\Java\jdk1.6.0_37

till jdk path (exclude bin folder)
now set JAVA_HOME into path as PATH=%JAVA_HOME%\bin;
This will set java path to all the applications which are using java.

For ANT use,

ANT_HOME=C:\Program Files (x86)\apache-ant-1.8.2\bin;

and include ANT_HOME into PATH, so path will look like PATH=%JAVA_HOME%\bin;%ANT_HOME%;

The OP's questions about canonical form and how it can improve performance of the equals method can both be answered by extending the example provided in Effective Java.

Consider the following class:

public final class CaseInsensitiveString {

  private final String s;

  public CaseInsensitiveString(String s) {
    this.s = Objects.requireNonNull(s);
  }

  @Override 
  public boolean equals(Object o) {
    return o instanceof CaseInsensitiveString && ((CaseInsensitiveString) o).s.equalsIgnoreCase(s);
  }
}

The equals method in this example has added cost by using String's equalsIgnoreCase method. As mentioned in the text

you may want to store a canonical form of the field so the equals method can do a cheap exact comparison on canonical forms rather than a more costly nonstandard comparison.

What does Joshua Bloch mean when he says canonical form? Well, I think Dónal's concise answer is very appropriate. We can store the underlying String field in the CaseInsensitiveString example in a standard way, perhaps the uppercase form of the String. Now, you can reference this canonical form of the CaseInsensitiveString, its uppercase variant, and perform cheap evaluations in your equals and hashcode methods.

I did some development with Mifare Classic (ISO 14443A) cards about 7-8 years ago. You can read and write to all sectors of the card, IIRC the only data you can't change is the serial number. Back then we used a proprietary library from Philips Semiconductors. The command interface to the card was quite alike the ISO 7816-4 (used with standard Smart Cards).

I'd recomment that you look at the OpenPCD platform if you are into development.

This is also of interest regarding the cryptographic functions in some RFID cards.

int number = Question.Role.GetHashCode();

number should have the value 2.

XMLHttpRequest is a standard object in the JavaScript Object model.

According to Wikipedia, XMLHttpRequest first appeared in Internet Explorer 5 as an ActiveX object, but has since been made into a standard and has been included for use in JavaScript in the Mozilla family since 1.0, Apple Safari 1.2, Opera 7.60-p1, and IE 7.0.

The open() method on the object takes the HTTP Method as an argument - and is specified as taking any valid HTTP method (see the item number 5 of the link) - including GET, POST, HEAD, PUT and DELETE, as specified by RFC 2616.

As a side note IE 7–8 only permit the following HTTP methods: "GET", "POST", "HEAD", "PUT", "DELETE", "MOVE", "PROPFIND", "PROPPATCH", "MKCOL", "COPY", "LOCK", "UNLOCK", and "OPTIONS".

Javascript does not support two dimensional arrays, instead we store an array inside another array and fetch the data from that array depending on what position of that array you want to access. Remember array numeration starts at ZERO.

Code Example:

/* Two dimensional array that's 5 x 5 

       C0 C1 C2 C3 C4 
    R0[1][1][1][1][1] 
    R1[1][1][1][1][1] 
    R2[1][1][1][1][1] 
    R3[1][1][1][1][1] 
    R4[1][1][1][1][1] 
*/

var row0 = [1,1,1,1,1],
    row1 = [1,1,1,1,1],
    row2 = [1,1,1,1,1],
    row3 = [1,1,1,1,1],
    row4 = [1,1,1,1,1];

var table = [row0,row1,row2,row3,row4];
console.log(table[0][0]); // Get the first item in the array

(ES5) I use forEach to iterate on the collection returned by querySelectorAll and it works well :

document.querySelectorAll('your_selector').forEach(item => { /* do the job with item element */ });

1. Enter into SETTING
2. Choose"Apps" & All
3. Select Google Services Framework
4. Clear data
5. Force stop
6. Go to Apps and download without error

Give this a try:

success: function(json) {
   console.log(JSON.stringify(json.topics));
   $.each(json.topics, function(idx, topic){
     $("#nav").html('<a href="' + topic.link_src + '">' + topic.link_text + "</a>");
   });
},

Use onkeypress . Check if the pressed key is enter (keyCode = 13). if yes, call the searching() function.

HTML

<input name="keywords" type="text" id="keywords" size="50"  onkeypress="handleKeyPress(event)">

JAVASCRIPT

function handleKeyPress(e){
 var key=e.keyCode || e.which;
  if (key==13){
     searching();
  }
}

Here is a snippet showing it in action:

document.getElementById("msg1").innerHTML = "Default";_x000D_
function handle(e){_x000D_
 document.getElementById("msg1").innerHTML = "Trigger";_x000D_
 var key=e.keyCode || e.which;_x000D_
  if (key==13){_x000D_
     document.getElementById("msg1").innerHTML = "HELLO!";_x000D_
  }_x000D_
}

<input type="text" name="box22" value="please" onkeypress="handle(event)"/>_x000D_
<div id="msg1"></div>

In plain terms, short-circuiting means stopping evaluation once you know that the answer can no longer change. For example, if you are evaluating a chain of logical ANDs and you discover a FALSE in the middle of that chain, you know the result is going to be false, no matter what are the values of the rest of the expressions in the chain. Same goes for a chain of ORs: once you discover a TRUE, you know the answer right away, and so you can skip evaluating the rest of the expressions.

You indicate to Java that you want short-circuiting by using && instead of & and || instead of |. The first set in your post is short-circuiting.

Note that this is more than an attempt at saving a few CPU cycles: in expressions like this

if (mystring != null && mystring.indexOf('+') > 0) {
    ...
}

short-circuiting means a difference between correct operation and a crash (in the case where mystring is null).

Like all other had said above, you need to add path. But not sure for what reason if I add C:\xampp\php in path of System Variable won't work but if I add it in path of User Variable work fine.

Although I had added and using other command line tools by adding in system variables work fine

So just in case if someone had same problem as me. Windows 10

Demo :

<connectionStrings>
<add name="myConnectionString" connectionString="server=localhost;database=myDb;uid=myUser;password=myPass;" />
</connectionStrings>

Based on your question:

<connectionStrings>
    <add name="itmall" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True" />
    </connectionStrings>

Refer links:

http://www.connectionstrings.com/store-connection-string-in-webconfig/

Retrive connection string from web.config file:

write the below code in your file where you want;

string connstring=ConfigurationManager.ConnectionStrings["itmall"].ConnectionString;

SqlConnection con = new SqlConnection(connstring);

or you can go in your way like

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["itmall"].ConnectionString);

Note:

The "name" which you gave in web.config file and name which you used in connection string must be same(like "itmall" in this solution.)

This is one way to do it (in Python 3.x):

escaped = a_string.translate(str.maketrans({"-":  r"\-",
                                          "]":  r"\]",
                                          "\\": r"\\",
                                          "^":  r"\^",
                                          "$":  r"\$",
                                          "*":  r"\*",
                                          ".":  r"\."}))

For reference, for escaping strings to use in regex:

import re
escaped = re.escape(a_string)

if it is a RSA key

openssl rsa  -pubout -in my_rsa_key.pem

if you need it in a format for openssh , please see Use RSA private key to generate public key?

Note that public key is generated from the private key and ssh uses the identity file (private key file) to generate and send public key to server and un-encrypt the encrypted token from the server via the private key in identity file.

Rotation Object programmatically.

// clockwise rotation :

    public void rotate_Clockwise(View view) {
        ObjectAnimator rotate = ObjectAnimator.ofFloat(view, "rotation", 180f, 0f);
//        rotate.setRepeatCount(10);
        rotate.setDuration(500);
        rotate.start();
    }

// AntiClockwise rotation :

 public void rotate_AntiClockwise(View view) {
        ObjectAnimator rotate = ObjectAnimator.ofFloat(view, "rotation", 0f, 180f);
//        rotate.setRepeatCount(10);
        rotate.setDuration(500);
        rotate.start();
    } 

view is object of your ImageView or other widgets.

rotate.setRepeatCount(10); use to repeat your rotation.

500 is your animation time duration.

You must specify the type of the column before the auto_increment directive, i.e. ALTER TABLE document MODIFY COLUMN document_id INT AUTO_INCREMENT.

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

I had the same issue as @Gravity Grave whereby scrolling doesn't work if you use

data-toggle="modal" data-target="TARGET-2" 

in conjunction with

data-dismiss="modal"

The scroll doesn't work correctly and reverts to scrolling the page rather than the modal. This is due to data-dismiss removing the modal-open class from the tag.

My solution in the end was to set the html of the inner component on the modal and use css to fade the text in/out.

I use Redgate backup pro 7 tools for this purpose. you can create mirror from backup file in create tile on other location. and can copy backup file after create on network and on host storage automatically.

A string literal is delimited by quotation marks and is of type char* not char.

Example: "hello"

So when you compare a char to a char* you will get that same compiling error.

char c = 'c';
char *p = "hello";

if(c==p)//compiling error
{
} 

To fix use a char literal which is delimited by single quotes.

Example: 'c'

For me I had to make sure the the program I was coping file to was not running at the time. There weren't any errors in the syntax. Hope this helps someone.

This answer is not related to the above question, but I faced a similar issue, and maybe this will be useful to someone. I am trying to merge my feature branch to master like below:

$ git merge fix-load

for this got the following error message:

merge: fix-load - not something we can merge

I looked into above all solutions, but not none of the worked.

Finally, I realized the issue cause is a spelling mistake on my branch name (actually, the merge branch name is fix-loads).

You should not attempt to parse HTML with regex. HTML is not a regular language, so any regex you come up with will likely fail on some esoteric edge case. Please refer to the seminal answer to this question for specifics. While mostly formatted as a joke, it makes a very good point.

The following examples are Java, but the regex will be similar -- if not identical -- for other languages.

String target = someString.replaceAll("<[^>]*>", "");

Assuming your non-html does not contain any < or > and that your input string is correctly structured.

If you know they're a specific tag -- for example you know the text contains only <td> tags, you could do something like this:

String target = someString.replaceAll("(?i)<td[^>]*>", "");

Edit: Omega brought up a good point in a comment on another post that this would result in multiple results all being squished together if there were multiple tags.

For example, if the input string were <td>Something</td><td>Another Thing</td>, then the above would result in SomethingAnother Thing.

In a situation where multiple tags are expected, we could do something like:

String target = someString.replaceAll("(?i)<td[^>]*>", " ").replaceAll("\\s+", " ").trim();

This replaces the HTML with a single space, then collapses whitespace, and then trims any on the ends.

How to update the current menu in order to enable or disable the items when an AsyncTask is done.

In my use case I needed to disable my menu while my AsyncTask was loading data, then after loading all the data, I needed to enable all the menu again in order to let the user use it.

This prevented the app to let users click on menu items while data was loading.

First, I declare a state variable , if the variable is 0 the menu is shown, if that variable is 1 the menu is hidden.

private mMenuState = 1; //I initialize it on 1 since I need all elements to be hidden when my activity starts loading.

Then in my onCreateOptionsMenu() I check for this variable , if it's 1 I disable all my items, if not, I just show them all

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_galeria_pictos, menu);

        if(mMenuState==1){
            for (int i = 0; i < menu.size(); i++) {
                menu.getItem(i).setVisible(false);
            }
        }else{
             for (int i = 0; i < menu.size(); i++) {
                menu.getItem(i).setVisible(true);
            }
        }

        return super.onCreateOptionsMenu(menu);
    }

Now, when my Activity starts, onCreateOptionsMenu() will be called just once, and all my items will be gone because I set up the state for them at the start.

Then I create an AsyncTask Where I set that state variable to 0 in my onPostExecute()

This step is very important!

When you call invalidateOptionsMenu(); it will relaunch onCreateOptionsMenu();

So, after setting up my state to 0, I just redraw all the menu but this time with my variable on 0 , that said, all the menu will be shown after all the asynchronous process is done, and then my user can use the menu.

 public class LoadMyGroups extends AsyncTask<Void, Void, Void> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            mMenuState = 1; //you can set here the state of the menu too if you dont want to initialize it at global declaration. 

        }

        @Override
        protected Void doInBackground(Void... voids) {
           //Background work

            return null;
        }

        @Override
        protected void onPostExecute(Void aVoid) {
            super.onPostExecute(aVoid);

            mMenuState=0; //We change the state and relaunch onCreateOptionsMenu
            invalidateOptionsMenu(); //Relaunch onCreateOptionsMenu

        }
    }

I'm going to suggest the non-obvious. There is a fantastic (and often under-used) tool called the Immediate Window in Visual Basic Editor. Basically, you can write out commands in VBA and execute them on the spot, sort of like command prompt. It's perfect for cases like this.

Press ALT+F11 to open VBE, then Control+G to open the Immediate Window. Type the following and hit enter:

for each v in range("K2:K5000") : v.value = "'" & v.value : next

And boom! You are all done. No need to create a macro, declare variables, no need to drag and copy, etc. Close the window and get back to work. The only downfall is to undo it, you need to do it via code since VBA will destroy your undo stack (but that's simple).

Its an old question I know but I did stumble across it so for future reference you can now do this:

pip uninstall [options] <package> ...
pip uninstall [options] -r <requirements file> ...

-r, --requirement file

Uninstall all the packages listed in the given requirements file. This option can be used multiple times.

from the pip documentation version 8.1

Very late answer :( but for someone who is in need, this works Angular js works too :) URLSearchParams Let's have a look at how we can use this new API to get values from the location!

// Assuming "?post=1234&action=edit"

var urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.has('post')); // true
console.log(urlParams.get('action')); // "edit"
console.log(urlParams.getAll('action')); // ["edit"]
console.log(urlParams.toString()); // "?post=1234&action=edit"
console.log(urlParams.append('active', '1')); // "?

post=1234&action=edit&active=1"

FYI: IE is not supported

use this function from instead of URLSearchParams

urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)')
                      .exec(window.location.search);

    return (results !== null) ? results[1] || 0 : false;
}

console.log(urlParam('action')); //edit

give the user $whoami to create somethin in those folder

sudo chown -R user /Library/Ruby/Gems/2.0.0

Try putting your text in another div inside your span:

i.e.

<span><div>some text</div></span>

UPDATE: As TimK pointed out, this isn't needed with jquery 1.5.2 any more. But if you want to add custom headers or allow the use of credentials (username, password, or cookies, etc), read on.

I think I found the answer! (4 hours and a lot of cursing later)

//This does not work!!
Access-Control-Allow-Headers: *

You need to manually specify all the headers you will accept (at least that was the case for me in FF 4.0 & Chrome 10.0.648.204).

jQuery's $.ajax method sends the "x-requested-with" header for all cross domain requests (i think its only cross domain).

So the missing header needed to respond to the OPTIONS request is:

//no longer needed as of jquery 1.5.2
Access-Control-Allow-Headers: x-requested-with

If you are passing any non "simple" headers, you will need to include them in your list (i send one more):

//only need part of this for my custom header
Access-Control-Allow-Headers: x-requested-with, x-requested-by

So to put it all together, here is my PHP:

// * wont work in FF w/ Allow-Credentials
//if you dont need Allow-Credentials, * seems to work
header('Access-Control-Allow-Origin: http://www.example.com');
//if you need cookies or login etc
header('Access-Control-Allow-Credentials: true');
if ($this->getRequestMethod() == 'OPTIONS')
{
  header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
  header('Access-Control-Max-Age: 604800');
  //if you need special headers
  header('Access-Control-Allow-Headers: x-requested-with');
  exit(0);
}

No need functions

For example to give color to a container using colorcode

Container (

color:Color(0xff000000)

)

Here the 0xff is the format followed by color code

Another approach to breaking out of a nested loop is to factor out both loops into a separate function, and return from that function when you want to exit.

Of course, this brings up the other argument of whether you should ever explicitly return from a function anywhere other than at the end.

Your additional threads must be initiated from the same app that is called by the WSGI server.

The example below creates a background thread that executes every 5 seconds and manipulates data structures that are also available to Flask routed functions.

import threading
import atexit
from flask import Flask

POOL_TIME = 5 #Seconds

# variables that are accessible from anywhere
commonDataStruct = {}
# lock to control access to variable
dataLock = threading.Lock()
# thread handler
yourThread = threading.Thread()

def create_app():
    app = Flask(__name__)

    def interrupt():
        global yourThread
        yourThread.cancel()

    def doStuff():
        global commonDataStruct
        global yourThread
        with dataLock:
        # Do your stuff with commonDataStruct Here

        # Set the next thread to happen
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()   

    def doStuffStart():
        # Do initialisation stuff here
        global yourThread
        # Create your thread
        yourThread = threading.Timer(POOL_TIME, doStuff, ())
        yourThread.start()

    # Initiate
    doStuffStart()
    # When you kill Flask (SIGTERM), clear the trigger for the next thread
    atexit.register(interrupt)
    return app

app = create_app()          

Call it from Gunicorn with something like this:

I my case I'd manually moved a .war file to /var/lib/tomcat9/webapps and unzipped it, then did "chown -R tomcat:tomcat *" in that directory and it resolved it.

If it works fine on your local environment, probably your remote server's IP is being blocked by the server at the target URL you've set for cURL to use. You need to verify that your remote server is allowed to access the URL you've set for CURLOPT_URL.

Update: As Roko C.Bulijan pointed out.. you need to use .insertAfter to insert it after the selected div. Also see updated code if you want it appended to the end instead of beginning when cloned multiple times. DEMO

Code:

   var cloneCount = 1;;
   $("button").click(function(){
      $('#id')
          .clone()
          .attr('id', 'id'+ cloneCount++)
          .insertAfter('[id^=id]:last') 
           //            ^-- Use '#id' if you want to insert the cloned 
           //                element in the beginning
          .text('Cloned ' + (cloneCount-1)); //<--For DEMO
   }); 

Try,

$("#id").clone().attr('id', 'id1').after("#id");

If you want a automatic counter, then see below,

   var cloneCount = 1;
   $("button").click(function(){
      $("#id").clone().attr('id', 'id'+ cloneCount++).insertAfter("#id");
   }); 

if your using sqlsrv_connect you have to download and install MS sql driver for your php. download it here http://www.microsoft.com/en-us/download/details.aspx?id=20098 extract it to your php folder or ext in xampp folder then add this on the end of the line in your php.ini file

extension=php_pdo_sqlsrv_55_ts.dll
extension=php_sqlsrv_55_ts.dll

im using xampp version 5.5 so its name php_pdo_sqlsrv_55_ts.dll & php_sqlsrv_55_ts.dll

if you are using xampp version 5.5 dll files is not included in the link...hope it helps

Use isinstance, nothing else:

if isinstance(x, pd.DataFrame):
    ... # do something

PEP8 says explicitly that isinstance is the preferred way to check types

No:  type(x) is pd.DataFrame
No:  type(x) == pd.DataFrame
Yes: isinstance(x, pd.DataFrame)

And don't even think about

if obj.__class__.__name__ = 'DataFrame':
    expect_problems_some_day()

isinstance handles inheritance (see What are the differences between type() and isinstance()?). For example, it will tell you if a variable is a string (either str or unicode), because they derive from basestring)

if isinstance(obj, basestring):
    i_am_string(obj)

Specifically for pandas DataFrame objects:

import pandas as pd
isinstance(var, pd.DataFrame)

use this method from everywhere with a context

private static String getCallDetails(Context context) {
    StringBuffer stringBuffer = new StringBuffer();
    Cursor cursor = context.getContentResolver().query(CallLog.Calls.CONTENT_URI,
            null, null, null, CallLog.Calls.DATE + " DESC");
    int number = cursor.getColumnIndex(CallLog.Calls.NUMBER);
    int type = cursor.getColumnIndex(CallLog.Calls.TYPE);
    int date = cursor.getColumnIndex(CallLog.Calls.DATE);
    int duration = cursor.getColumnIndex(CallLog.Calls.DURATION);       
    while (cursor.moveToNext()) {
        String phNumber = cursor.getString(number);
        String callType = cursor.getString(type);
        String callDate = cursor.getString(date);
        Date callDayTime = new Date(Long.valueOf(callDate));
        String callDuration = cursor.getString(duration);
        String dir = null;
        int dircode = Integer.parseInt(callType);
        switch (dircode) {
        case CallLog.Calls.OUTGOING_TYPE:
            dir = "OUTGOING";
            break;
        case CallLog.Calls.INCOMING_TYPE:
            dir = "INCOMING";
            break;

        case CallLog.Calls.MISSED_TYPE:
            dir = "MISSED";
            break;

Can you write virtual functions in Java?

Yes. In fact, all instance methods in Java are virtual by default. Only certain methods are not virtual:

• Class methods (because typically each instance holds information like a pointer to a vtable about its specific methods, but no instance is available here).
• Private instance methods (because no other class can access the method, the calling instance has always the type of the defining class itself and is therefore unambiguously known at compile time).

Here are some examples:

"Normal" virtual functions

The following example is from an old version of the wikipedia page mentioned in another answer.

import java.util.*;

public class Animal 
{
   public void eat() 
   { 
      System.out.println("I eat like a generic Animal."); 
   }

   public static void main(String[] args) 
   {
      List<Animal> animals = new LinkedList<Animal>();

      animals.add(new Animal());
      animals.add(new Fish());
      animals.add(new Goldfish());
      animals.add(new OtherAnimal());

      for (Animal currentAnimal : animals) 
      {
         currentAnimal.eat();
      }
   }
}

class Fish extends Animal 
{
   @Override
   public void eat() 
   { 
      System.out.println("I eat like a fish!"); 
   }
}

class Goldfish extends Fish 
{
   @Override
   public void eat() 
   { 
      System.out.println("I eat like a goldfish!"); 
   }
}

class OtherAnimal extends Animal {}

Output:

I eat like a generic Animal.
I eat like a fish!
I eat like a goldfish!
I eat like a generic Animal.

Example with virtual functions with interfaces

Java interface methods are all virtual. They must be virtual because they rely on the implementing classes to provide the method implementations. The code to execute will only be selected at run time.

For example:

interface Bicycle {         //the function applyBrakes() is virtual because
    void applyBrakes();     //functions in interfaces are designed to be 
}                           //overridden.

class ACMEBicycle implements Bicycle {
    public void applyBrakes(){               //Here we implement applyBrakes()
       System.out.println("Brakes applied"); //function
    }
}

Example with virtual functions with abstract classes.

Similar to interfaces Abstract classes must contain virtual methods because they rely on the extending classes' implementation. For Example:

abstract class Dog {                   
    final void bark() {               //bark() is not virtual because it is 
        System.out.println("woof");   //final and if you tried to override it
    }                                 //you would get a compile time error.

    abstract void jump();             //jump() is a "pure" virtual function 
}                                     
class MyDog extends Dog{
    void jump(){
        System.out.println("boing");    //here jump() is being overridden
    }                                  
}
public class Runner {
    public static void main(String[] args) {
        Dog dog = new MyDog();       // Create a MyDog and assign to plain Dog variable
        dog.jump();                  // calling the virtual function.
                                     // MyDog.jump() will be executed 
                                     // although the variable is just a plain Dog.
    }
}

This will give you an array of the starting indices for matches to yourstring:

import re
indices = [s.start() for s in re.finditer(':', yourstring)]

Then your nth entry would be:

n = 2
nth_entry = indices[n-1]

Of course you have to be careful with the index bounds. You can get the number of instances of yourstring like this:

num_instances = len(indices)

This is working fine for me:

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
            int rawContactInsertIndex = ops.size();

            ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
                    .withValue(RawContacts.ACCOUNT_TYPE, null)
                    .withValue(RawContacts.ACCOUNT_NAME, null).build());
            ops.add(ContentProviderOperation
                    .newInsert(Data.CONTENT_URI)
                    .withValueBackReference(Data.RAW_CONTACT_ID,rawContactInsertIndex)
                    .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
                    .withValue(StructuredName.DISPLAY_NAME, "Vikas Patidar") // Name of the person
                    .build());
            ops.add(ContentProviderOperation
                    .newInsert(Data.CONTENT_URI)
                    .withValueBackReference(
                            ContactsContract.Data.RAW_CONTACT_ID,   rawContactInsertIndex)
                    .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
                    .withValue(Phone.NUMBER, "9999999999") // Number of the person
                    .withValue(Phone.TYPE, Phone.TYPE_MOBILE).build()); // Type of mobile number                    
            try
            {
                ContentProviderResult[] res = getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
            }
            catch (RemoteException e)
            { 
                // error
            }
            catch (OperationApplicationException e) 
            {
                // error
            }       

KEYS pattern

Available since 1.0.0.

Time complexity: O(N) with N being the number of keys in the database, under the assumption that the key names in the database and the given pattern have limited length.

Returns all keys matching pattern.

Warning : This command is not recommended to use because it may ruin performance when it is executed against large databases instead of KEYS you can use SCAN or SETS.

Example of KEYS command to use :

redis> MSET firstname Jack lastname Stuntman age 35
"OK"
redis> KEYS *name*
1) "lastname"
2) "firstname"
redis> KEYS a??
1) "age"
redis> KEYS *
1) "lastname"
2) "age"
3) "firstname"

You can use SpicyTaco.AutoGrid - a modified version of StackPanel:

<st:StackPanel Orientation="Horizontal" MarginBetweenChildren="10" Margin="10">
   <Button Content="Info" HorizontalAlignment="Left" st:StackPanel.Fill="Fill"/>
   <Button Content="Cancel"/>
   <Button Content="Save"/>
</st:StackPanel>

First button will be fill.

You can install it via NuGet:

Install-Package SpicyTaco.AutoGrid

I recommend taking a look at SpicyTaco.AutoGrid. It's very useful for forms in WPF instead of DockPanel, StackPanel and Grid and solve problem with stretching very easy and gracefully. Just look at readme on GitHub.

<st:AutoGrid Columns="160,*" ChildMargin="3">
    <Label Content="Name:"/>
    <TextBox/>

    <Label Content="E-Mail:"/>
    <TextBox/>

    <Label Content="Comment:"/>
    <TextBox/>
</st:AutoGrid>

Add property ViewStateMode="Enabled" and EnableViewState="true" And AutoPostBack="true" in drop DropDownList

Not sure if this is what you were looking for, but this worked for me:

$query = query("DESC YourTable");  
$col_names = array_column($query, 'Field');

That returns a simple array of the column names / variable names in your table or array as strings, which is what I needed to dynamically build MySQL queries. My frustration was that I simply don't know how to index arrays in PHP very well, so I wasn't sure what to do with the results from DESC or SHOW. Hope my answer is helpful to beginners like myself!

To check result: print_r($col_names);

Escape your HTML tags ...

<resources>
    <string name="somestring">
        &lt;B&gt;Title&lt;/B&gt;&lt;BR/&gt;
        Content
    </string>
</resources>

is it possible to extend query results with literals like this?

Yes.

Select Name
From Customers
UNION ALL
Select 'Jason'

• Use UNION to add Jason if it isn't already in the result set.
• Use UNION ALL to add Jason whether or not he's already in the result set.

I'm surprised nobody has mentioned the Yeoman generator angular-fullstack. It is the number one Yeoman community generator, with currently 1490 stars on the generator page vs Mean.js' 81 stars (admittedly not a fair comparison given how new MEANJS is). It is appears to be actively maintained and is in version 2.05 as I write this. Unlike MEANJS, it doesn't use Swig for templating. It can be scaffolded with passport built in.

Ran into a similar issue today. In my case, it was the shade plugin that was the culprit, in addition to springframework.org having an outage. The following snippet cleared things up:

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
   <resource>META-INF/spring.schemas</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
    <resource>META-INF/spring.handlers</resource>
</transformer>

HTH someone

Try this. Just add an empty option. This will solve your problem.

<select onchange="jsFunction()">
    <option></option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
</select>?

There are various methods to get an input textbox value directly (without wrapping the input element inside a form element):

Method 1:

document.getElementById('textbox_id').value to get the value of desired box

For example, document.getElementById("searchTxt").value;

Note: Method 2,3,4 and 6 returns a collection of elements, so use [whole_number] to get the desired occurrence. For the first element, use [0], for the second one use 1, and so on...

Method 2:

Use document.getElementsByClassName('class_name')[whole_number].value which returns a Live HTMLCollection

For example, document.getElementsByClassName("searchField")[0].value; if this is the first textbox in your page.

Method 3:

Use document.getElementsByTagName('tag_name')[whole_number].value which also returns a live HTMLCollection

For example, document.getElementsByTagName("input")[0].value;, if this is the first textbox in your page.

Method 4:

document.getElementsByName('name')[whole_number].value which also >returns a live NodeList

For example, document.getElementsByName("searchTxt")[0].value; if this is the first textbox with name 'searchtext' in your page.

Method 5:

Use the powerful document.querySelector('selector').value which uses a CSS selector to select the element

For example, document.querySelector('#searchTxt').value; selected by id
document.querySelector('.searchField').value; selected by class
document.querySelector('input').value; selected by tagname
document.querySelector('[name="searchTxt"]').value; selected by name

Method 6:

document.querySelectorAll('selector')[whole_number].value which also uses a CSS selector to select elements, but it returns all elements with that selector as a static Nodelist.

For example, document.querySelectorAll('#searchTxt')[0].value; selected by id
document.querySelectorAll('.searchField')[0].value; selected by class
document.querySelectorAll('input')[0].value; selected by tagname
document.querySelectorAll('[name="searchTxt"]')[0].value; selected by name

You can also use this extension method to easily register a handler for item property change in relevant collections. This method is automatically added to all the collections implementing INotifyCollectionChanged that hold items that implement INotifyPropertyChanged:

public static class ObservableCollectionEx
{
    public static void SetOnCollectionItemPropertyChanged<T>(this T _this, PropertyChangedEventHandler handler)
        where T : INotifyCollectionChanged, ICollection<INotifyPropertyChanged> 
    {
        _this.CollectionChanged += (sender,e)=> {
            if (e.NewItems != null)
            {
                foreach (Object item in e.NewItems)
                {
                    ((INotifyPropertyChanged)item).PropertyChanged += handler;
                }
            }
            if (e.OldItems != null)
            {
                foreach (Object item in e.OldItems)
                {
                    ((INotifyPropertyChanged)item).PropertyChanged -= handler;
                }
            }
        };
    }
}

How to use:

public class Test
{
    public static void MyExtensionTest()
    {
        ObservableCollection<INotifyPropertyChanged> c = new ObservableCollection<INotifyPropertyChanged>();
        c.SetOnCollectionItemPropertyChanged((item, e) =>
        {
             //whatever you want to do on item change
        });
    }
}

Just remove the line toggle.toggle(); from your click listener toggle() method will always reset your toggle button value.

And as you are trying to take the value of EditText in string variable which always remains same as you are getting value in onCreate() so better directly use the EditText to get the value of it in your onClick listener.

Just change your code as below its working fine now.

  btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
                       //toggle.toggle();
            if ( ed.getText().toString().equalsIgnoreCase("1")) {

                toggle.setTextOff("TOGGLE ON");
                toggle.setChecked(true);
            } else if ( ed.getText().toString().equalsIgnoreCase("0")) {

                toggle.setTextOn("TOGGLE OFF");
                toggle.setChecked(false);

            }
        }
    });

Here is the solution I found on Hibernate 4.1.9. I had to pass a parameter to my query that can have value NULL sometimes. So I passed the using:

setParameter("orderItemId", orderItemId, new LongType())

After that, I use the following where clause in my query:

where ((:orderItemId is null) OR (orderItem.id != :orderItemId))

As you can see, I am using the Query.setParameter(String, Object, Type) method, where I couldn't use the Hibernate.LONG that I found in the documentation (probably that was on older versions). For a full set of options of type parameter, check the list of implementation class of org.hibernate.type.Type interface.

Hope this helps!

The interviewer might have be looking for a circular reference solution:

    public static void main(String[] args) {
        while (true) {
            Element first = new Element();
            first.next = new Element();
            first.next.next = first;
        }
    }

This is a classic problem with reference counting garbage collectors. You would then politely explain that JVMs use a much more sophisticated algorithm that doesn't have this limitation.

You can use arguments with default values.

def someMethod(def mandatory,def optional=null){}

if argument "optional" not exist, it turns to "null".

Late to the party, but I think this addition might be useful for people working with rmarkdown. In rmarkdown there is built-in support for references to headers in your document.

Any header defined by

# Header

can be referenced by

get me back to that [header](#header)

The following is a minimal standalone .rmd file that shows this behavior. It can be knitted to .pdf and .html.

title: "references in rmarkdown"
output:
  html_document: default
  pdf_document: default
---

# Header

Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. 

Go back to that [header](#header).

Collection is a high-level interface describing Java objects that can contain collections of other objects. It's not very specific about how they are accessed, whether multiple copies of the same object can exist in the same collection, or whether the order is important. List is specifically an ordered collection of objects. If you put objects into a List in a particular order, they will stay in that order.

And deciding where to use these two interfaces is much less important than deciding what the concrete implementation you use is. This will have implications for the time and space performance of your program. For example, if you want a list, you could use an ArrayList or a LinkedList, each of which is going to have implications for the application. For other collection types (e.g. Sets), similar considerations apply.

Use the python3-style print function for python2.6+ (will also break any existing keyworded print statements in the same file.)

# for python2 to use the print() function, removing the print keyword
from __future__ import print_function
for x in xrange(10):
    print('.', end='')

To not ruin all your python2 print keywords, create a separate printf.py file

# printf.py

from __future__ import print_function

def printf(str, *args):
    print(str % args, end='')

Then, use it in your file

from printf import printf
for x in xrange(10):
    printf('.')
print 'done'
#..........done

More examples showing printf style

printf('hello %s', 'world')
printf('%i %f', 10, 3.14)
#hello world10 3.140000

REPEAT

or:

$(this).text()

The val() is for form fields only.

You can use a simple regex like this:

public static string StripHTML(string input)
{
   return Regex.Replace(input, "<.*?>", String.Empty);
}

Be aware that this solution has its own flaw. See Remove HTML tags in String for more information (especially the comments of @mehaase)

Another solution would be to use the HTML Agility Pack.
You can find an example using the library here: HTML agility pack - removing unwanted tags without removing content?

try to change your method if you need to loop!

within the parent stored procedure, create a #temp table that contains the data that you need to process. Call the child stored procedure, the #temp table will be visible and you can process it, hopefully working with the entire set of data and without a cursor or loop.

this really depends on what this child stored procedure is doing. If you are UPDATE-ing, you can "update from" joining in the #temp table and do all the work in one statement without a loop. The same can be done for INSERT and DELETEs. If you need to do multiple updates with IFs you can convert those to multiple UPDATE FROM with the #temp table and use CASE statements or WHERE conditions.

When working in a database try to lose the mindset of looping, it is a real performance drain, will cause locking/blocking and slow down the processing. If you loop everywhere, your system will not scale very well, and will be very hard to speed up when users start complaining about slow refreshes.

Post the content of this procedure you want call in a loop, and I'll bet 9 out of 10 times, you could write it to work on a set of rows.

This worked for me:

PowerShell.exe -Command "& ""C:\Some Script\Path With Spaces.ps1"""

The key seems to be that the whole command is enclosed in outer quotes, the "&" ampersand is used to specify another child command file is being executed, then finally escaped (doubled-double-) quotes around the path/file name with spaces in you wanted to execute in the first place.

This is also completion of the only workaround to the MS connect issue that -File does not pass-back non-zero return codes and -Command is the only alternative. But until now it was thought a limitation of -Command was that it didn't support spaces. I've updated that feedback item too.

Simple way to remove drop down arrow from select

select {_x000D_

}

<select>_x000D_
  <option>2000</option>_x000D_
  <option>2001</option>_x000D_
  <option>2002</option>_x000D_
</select>

It's because Arrays.asList(array) return List<int[]>. array argument is treated as one value you want to wrap (you get list of arrays of ints), not as vararg.

Note that it does work with object types (not primitives):

public boolean contains(final String[] array, final String key) {
    return Arrays.asList(array).contains(key);
}

or even:

public <T>  boolean contains(final T[] array, final T key) {
    return Arrays.asList(array).contains(key);
}

But you cannot have List<int> and autoboxing is not working here.

Running adb commands on all connected devices

Create a bash (adb+)

adb devices | while read line
do
if [ ! "$line" = "" ] && [ `echo $line | awk '{print $2}'` = "device" ]
then
    device=`echo $line | awk '{print $1}'`
    echo "$device $@ ..."
    adb -s $device $@
fi

done use it with

adb+ //+ command

Just another solution using underscore.js:

_.extend({}, obj1, obj2);

You can get the id of the last transaction by running lastInsertId() method on the connection object($conn).

Like this $lid = $conn->lastInsertId();

• F# Has Better Performance than C# in Math
• You could use F# projects in the same solution with C# (and call from one to another)
• F# is really good for complex algorithmic programming, financial and scientific applications
• F# logically is really good for the parallel execution (it is easier to make F# code execute on parallel cores, than C#)

Hit F4 and you'll get what you are looking for.

My best way to do this is, that i open the Code Definition Window, under View -> Code Definition Window or press Ctrl + W,D .

And then i got it floated and i have the definitions of methods in separate windows.

If anyone wants to debug release build using Android Studio, follow these steps:

1. Set build variant to release mode.

2. Right click on app in left navigation pane, click Open Module Settings.

3. Go to Signing Tab. Add a signing config and fill in information. Select your keychain as well.

4. Go to Build Type tab. Select release mode and set:

-Debuggable to true.

-Signing Config to the config. (The one you just created).

Sync your gradle. Enjoy!

Some compilers support compound literals as an extention, allowing this construct:

Customer customerRecords[2];
customerRecords[0] = (Customer){25, "Bob Jones"};
customerRecords[1] = (Customer){26, "Jim Smith"};

But it's rather unportable.

I have seen IFRAMEs applied very successfully as an easy way to make dynamic context menus, but the target audience of that web-app was only Internet Explorer users.

I would say that it all depends on your requirements. If you wish to make sure your page works equally well on every browser, avoid IFRAMEs. If you are targeting a narrow and well-known audience (eg. on the local Intranet) and you see a benefit in using IFRAMEs then I would say it's OK to do so.

I've found this solution by googling. I have just had this problem and it solved it.

My mistake was to put a project in other location out of the workspace, and share this workspace between several computers, where the paths difer. I learned that, when a project is out of workspace, its location is saved in workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location

Deleting .location and reimporting the project into workspace solved the issue. Hope this helps.

I solved this problem on windows 8 and windows 10 pro with this tutorial. I try a lot of times to solve this problem with many different solutions, but only worked for me with this: http://www.serverpals.com/blog/building-using-node-gyp-with-visual-studio-express-2015-on-windows-10-pro-x64 I notice that i didn't use nodist to control the node version like this tutorial, I use NVM and worked fine, i don't test this tutorial with nodist. I used node 5.2.0.

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

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

Note that double quotes strings escape \'s.

'C:\projects\blah.dll'.split('\\').last

if you are already using jQuery in your build just do this:

$(yourObject).length

It works nicely for me on objects, and I already had jQuery as a dependancy.

It all depends in what you understand as phone number. Phone numbers are country specific. The localflavors packages for several countries contains their own "phone number field". So if you are ok being country specific you should take a look at localflavor package (class us.models.PhoneNumberField for US case, etc.)

Otherwise you could inspect the localflavors to get the maximun lenght for all countries. Localflavor also has forms fields you could use in conjunction with the country code to validate the phone number.

With integers, it's preference.

If the loop variable is a class/object, it can make a difference (only profiling can tell you if it's a significant difference), because the post-increment version requires that you create a copy of that object that gets discarded.

If creating that copy is an expensive operation, you're paying that expense once for every time you go through the loop, for no reason at all.

If you get into the habit of always using ++i in for loops, you don't need to stop and think about whether what you're doing in this particular situation makes sense. You just always are.

Another way: add windowNoTitle and windowFullscreen attributes directly to the theme (you can find styles.xml file in res/values/ directory):

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
</style>

in the manifest file, in application specify your theme

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

You can index into a string in C# like an array, and you get the character at that index.

Example:

In Java, you would say

str.charAt(8);

In C#, you would say

str[8];

Make sure you have the following in both your site Web.config and views directory Web.config in the appSettings section

<add key="webpages:Version" value="2.0.0.0" />

For MVC5 use:

<add key="webpages:Version" value="3.0.0.0" />

(And it only exists in the main Web.config file.)

If user enters 34abc and you pass them to atoi it will return 34. If you want to validate the value entered then you have to use isdigit on the entered string iteratively

This worked in ubuntu 16.04 for python 2.7:

sudo pip install mysql-connector

Add these attributes to your EditText

android:focusable="true"
android:focusableInTouchMode="true"

After this in your code you can simply write

editText.clearFocus()

argument exception.

• System.ArgumentException
• System.ArgumentNullException
• System.ArgumentOutOfRangeException

You can use inline styling to limit the height:

<img src="" class="img-responsive" alt="" style="max-height: 400px;">

Set a breakpoint on malloc_error_break() by opening the Breakpoint Navigator (View->Navigators->Show Breakpoint Navigator or ?8), clicking the plus button in the lower left corner, and selecting "Add Symbolic Breakpoint". In the popup that comes up, enter malloc_error_break in the Symbol field, then click Done.

EDIT: openfrog added a screenshot and indicated that he's already tried these steps without success after I posted my answer. With that edit, I'm not sure what to say. I haven't seen that fail to work myself, and indeed I always keep a breakpoint on malloc_error_break set.

Aside from getting decode and encode backwards, I think part of the answer here is actually don't use the ascii encoding. It's probably not what you want.

To begin with, think of str like you would a plain text file. It's just a bunch of bytes with no encoding actually attached to it. How it's interpreted is up to whatever piece of code is reading it. If you don't know what this paragraph is talking about, go read Joel's The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets right now before you go any further.

Naturally, we're all aware of the mess that created. The answer is to, at least within memory, have a standard encoding for all strings. That's where unicode comes in. I'm having trouble tracking down exactly what encoding Python uses internally for sure, but it doesn't really matter just for this. The point is that you know it's a sequence of bytes that are interpreted a certain way. So you only need to think about the characters themselves, and not the bytes.

The problem is that in practice, you run into both. Some libraries give you a str, and some expect a str. Certainly that makes sense whenever you're streaming a series of bytes (such as to or from disk or over a web request). So you need to be able to translate back and forth.

Enter codecs: it's the translation library between these two data types. You use encode to generate a sequence of bytes (str) from a text string (unicode), and you use decode to get a text string (unicode) from a sequence of bytes (str).

For example:

>>> s = "I look like a string, but I'm actually a sequence of bytes. \xe2\x9d\xa4"
>>> codecs.decode(s, 'utf-8')
u"I look like a string, but I'm actually a sequence of bytes. \u2764"

What happened here? I gave Python a sequence of bytes, and then I told it, "Give me the unicode version of this, given that this sequence of bytes is in 'utf-8'." It did as I asked, and those bytes (a heart character) are now treated as a whole, represented by their Unicode codepoint.

Let's go the other way around:

>>> u = u"I'm a string! Really! \u2764"
>>> codecs.encode(u, 'utf-8')
"I'm a string! Really! \xe2\x9d\xa4"

I gave Python a Unicode string, and I asked it to translate the string into a sequence of bytes using the 'utf-8' encoding. So it did, and now the heart is just a bunch of bytes it can't print as ASCII; so it shows me the hexadecimal instead.

We can work with other encodings, too, of course:

>>> s = "I have a section \xa7"
>>> codecs.decode(s, 'latin1')
u'I have a section \xa7'
>>> codecs.decode(s, 'latin1')[-1] == u'\u00A7'
True

>>> u = u"I have a section \u00a7"
>>> u
u'I have a section \xa7'
>>> codecs.encode(u, 'latin1')
'I have a section \xa7'

('\xa7' is the section character, in both Unicode and Latin-1.)

So for your question, you first need to figure out what encoding your str is in.

• Did it come from a file? From a web request? From your database? Then the source determines the encoding. Find out the encoding of the source and use that to translate it into a unicode.

  s = [get from external source]
  u = codecs.decode(s, 'utf-8') # Replace utf-8 with the actual input encoding
  

• Or maybe you're trying to write it out somewhere. What encoding does the destination expect? Use that to translate it into a str. UTF-8 is a good choice for plain text documents; most things can read it.

  u = u'My string'
  s = codecs.encode(u, 'utf-8') # Replace utf-8 with the actual output encoding
  [Write s out somewhere]
  

• Are you just translating back and forth in memory for interoperability or something? Then just pick an encoding and stick with it; 'utf-8' is probably the best choice for that:

  u = u'My string'
  s = codecs.encode(u, 'utf-8')
  newu = codecs.decode(s, 'utf-8')
  

In modern programming, you probably never want to use the 'ascii' encoding for any of this. It's an extremely small subset of all possible characters, and no system I know of uses it by default or anything.

Python 3 does its best to make this immensely clearer simply by changing the names. In Python 3, str was replaced with bytes, and unicode was replaced with str.

Well, I meant that I need to parse object like this: var jsonObj = {"first name" : "fname"}. But, I don't actually. Because it's already an JSON.

Another option is:

when:

def response = mockMvc.perform(
            get('/path/to/api')
            .header("Content-Type", "application/json"))

then:

response.andExpect(status().isOk())
response.andReturn().getResponse().getContentAsString() == "what you expect"

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%') 
END

The term "clone" is ambiguous (though the Java class library includes a Cloneable interface) and can refer to a deep copy or a shallow copy. Deep/shallow copies are not specifically tied to Java but are a general concept relating to making a copy of an object, and refers to how members of an object are also copied.

As an example, let's say you have a person class:

class Person {
    String name;
    List<String> emailAddresses
}

How do you clone objects of this class? If you are performing a shallow copy, you might copy name and put a reference to emailAddresses in the new object. But if you modified the contents of the emailAddresses list, you would be modifying the list in both copies (since that's how object references work).

A deep copy would mean that you recursively copy every member, so you would need to create a new List for the new Person, and then copy the contents from the old to the new object.

Although the above example is trivial, the differences between deep and shallow copies are significant and have a major impact on any application, especially if you are trying to devise a generic clone method in advance, without knowing how someone might use it later. There are times when you need deep or shallow semantics, or some hybrid where you deep copy some members but not others.

Simple jQuery plugin for delayed window resize event.

SYNTAX:

Add new function to resize event

jQuery(window).resizeDelayed( func, delay, id ); // delay and id are optional

Remove the function(by declaring its ID) added earlier

jQuery(window).resizeDelayed( false, id );

Remove all functions

jQuery(window).resizeDelayed( false );

USAGE:

// ADD SOME FUNCTIONS TO RESIZE EVENT
jQuery(window).resizeDelayed( function(){ console.log( 'first event - should run after 0.4 seconds'); }, 400,  'id-first-event' );
jQuery(window).resizeDelayed( function(){ console.log('second event - should run after 1.5 seconds'); }, 1500, 'id-second-event' );
jQuery(window).resizeDelayed( function(){ console.log( 'third event - should run after 3.0 seconds'); }, 3000, 'id-third-event' );

// LETS DELETE THE SECOND ONE
jQuery(window).resizeDelayed( false, 'id-second-event' );

// LETS ADD ONE WITH AUTOGENERATED ID(THIS COULDNT BE DELETED LATER) AND DEFAULT TIMEOUT (500ms)
jQuery(window).resizeDelayed( function(){ console.log('newest event - should run after 0.5 second'); } );

// LETS CALL RESIZE EVENT MANUALLY MULTIPLE TIMES (OR YOU CAN RESIZE YOUR BROWSER WINDOW) TO SEE WHAT WILL HAPPEN
jQuery(window).resize().resize().resize().resize().resize().resize().resize();

USAGE OUTPUT:

first event - should run after 0.4 seconds
newest event - should run after 0.5 second
third event - should run after 3.0 seconds

PLUGIN:

If something happens in any browser I'd be surprised. This is one of those outstanding form elements that browsers tend not to let you style that much, and that people usually try to replace with javascript so they can style/code something to look and act like a checkbox.

Coming here from first Google hit:

You can turn off the behavior AND and warning by exporting GIT_DISCOVERY_ACROSS_FILESYSTEM=1.

On heroku, if you heroku config:set GIT_DISCOVERY_ACROSS_FILESYSTEM=1 the warning will go away.

It's probably because you are building a gem from source and the gemspec shells out to git, like many do today. So, you'll still get the warning fatal: Not a git repository (or any of the parent directories): .git but addressing that is for another day :)

My answer is a duplicate of: - comment GIT_DISCOVERY_ACROSS_FILESYSTEM problem when working with terminal and MacFusion

When you look up your php-fpm.conf

example location:
cat /usr/src/php/sapi/fpm/php-fpm.conf

you will see, that you need to configure the PHP FastCGI Process Manager to actually use Unix sockets. Per default, the listen directive` is set up to listen on a TCP socket on one port. If there's no Unix socket defined, you won't find a Unix socket file.

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all IPv4 addresses on a
;                            specific port;
;   '[::]:port'            - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000

You are looking for CHAR_LENGTH() to get the number of characters in a string.

For multi-byte charsets LENGTH() will give you the number of bytes the string occupies, while CHAR_LENGTH() will return the number of characters.

with MySQL version 5.7.28 check by using
SELECT @@sql_mode; and update with

SET @@sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

I dont see anyone mentioning the ClassInitialize attribute method. The attributes are pretty straight forward.

Create methods that are marked with either the [ClassInitialize()] or [TestInitialize()] attribute to prepare aspects of the environment in which your unit test will run. The purpose of this is to establish a known state for running your unit test. For example, you may use the [ClassInitialize()] or the [TestInitialize()] method to copy, alter, or create certain data files that your test will use.

Create methods that are marked with either the [ClassCleanup()] or [TestCleanUp{}] attribute to return the environment to a known state after a test has run. This might mean the deletion of files in folders or the return of a database to a known state. An example of this is to reset an inventory database to an initial state after testing a method that is used in an order-entry application.

• [ClassInitialize()] Use ClassInitialize to run code before you run the first test in the class.

• [ClassCleanUp()] Use ClassCleanup to run code after all tests in a class have run.

• [TestInitialize()] Use TestInitialize to run code before you run each test.

• [TestCleanUp()] Use TestCleanup to run code after each test has run.

If you have a text box to type the file path, just use sendkeys to input the file path and click on submit button. If there is no text box to type the file path and only able to click on browse button and to select the file from windows popup, you can use AutoIt tool, see the step below to use AutoIt for the same,

1. Download and Install Autoit tool from http://www.autoitscript.com/site/autoit/

2. Open Programs -> Autoit tool -> SciTE Script Editor.

3. Paste the following code in Autoit editor and save it as “filename.exe “(eg: new.exe)

   Then compile and build the file to make it exe. (Tools ? Compile)

Autoit Code:

WinWaitActive("File Upload"); Name of the file upload window (Windows Popup Name: File Upload)    
Send("logo.jpg"); File name    
Send("{ENTER}")

Then Compile and Build from Tools menu of the Autoit tool -> SciTE Script Editor.

Paste the below Java code in Eclipse editor and save

Java Code:

driver.findElement(By.id("uploadbutton")).click; // open the Upload window using selenium    
Thread.sleep("20000"); // wait for page load    
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "C:\\Documents and Settings\\new.exe"); // Give  path where the exe is saved.

By default, the runserver command starts the development server on the internal IP at port 8000.

If you want to change the server’s port, pass it as a command-line argument. For instance, this command starts the server on port 8080:

python manage.py runserver 8080

An add-on to the previous answers since I came across this concern:

If you really want to insert something like 24-May-2005 to your DATE column, you could do something like this:

INSERT INTO someTable(Empid,Date_Joined)
VALUES
    ('S710',STR_TO_DATE('24-May-2005', '%d-%M-%Y'));

In the above query please note that if it's May(ie: the month in letters) the format should be %M.

NOTE: I tried this with the latest MySQL version 8.0 and it works!

This

public static bool GetBit(this byte b, int bitNumber) {
   return (b & (1 << bitNumber)) != 0;
}

should do it, I think.

select * from mytable where year(Columnx) = 2010

Regarding index usage (answering Simon's comment):

if you have an index on Columnx, SQLServer WON'T use it if you use the function "year" (or any other function).

There are two possible solutions for it, one is doing the search by interval like Columnx>='01012010' and Columnx<='31122010' and another one is to create a calculated column with the year(Columnx) expression, index it, and then do the filter on this new column

AffineTransform instances can be concatenated (added together). Therefore you can have a transform that combines 'shift to origin', 'rotate' and 'shift back to desired position'.

You can run ruby commands in one line with the -e flag:

ruby -e "puts 'hi'"

Check the man page for more information.

A nice option is to use tar -tvvf <filePath> which adds a line that reports the kind of file.

Example in a valid .tar file:

0 is conditional value when this condition is true, loop will keep executing.10 is the initial value. 1 is the modifier where may be simple decrement.

for number in reversed(range(0,10,1)):
print number;

About this solution, we could just create a directive and attach it to the DOM element that has to get the focus when a given condition is satisfied. By following this approach we avoid coupling controller to DOM element ID's.

Sample code directive:

gbndirectives.directive('focusOnCondition', ['$timeout',
    function ($timeout) {
        var checkDirectivePrerequisites = function (attrs) {
          if (!attrs.focusOnCondition && attrs.focusOnCondition != "") {
                throw "FocusOnCondition missing attribute to evaluate";
          }
        }

        return {            
            restrict: "A",
            link: function (scope, element, attrs, ctrls) {
                checkDirectivePrerequisites(attrs);

                scope.$watch(attrs.focusOnCondition, function (currentValue, lastValue) {
                    if(currentValue == true) {
                        $timeout(function () {                                                
                            element.focus();
                        });
                    }
                });
            }
        };
    }
]);

A possible usage

.controller('Ctrl', function($scope) {
   $scope.myCondition = false;
   // you can just add this to a radiobutton click value
   // or just watch for a value to change...
   $scope.doSomething = function(newMyConditionValue) {
       // do something awesome
       $scope.myCondition = newMyConditionValue;
  };

});

HTML

<input focus-on-condition="myCondition">

T-SQL is not asynchronous, so you really have no choice but to wait until SP2 ends. Luckily, that's what you want.

CREATE PROCEDURE SP1 AS
   EXEC SP2
   PRINT 'Done'

ansible-playbook test.yml --extra-vars "arg1=${var1} arg2=${var2}"

In the yml file you can use them like this

---
arg1: "{{ var1 }}"
arg2: "{{ var2 }}"

Also, --extra-vars and -e are the same, you can use one of them.

Set a local value with the observer

...also, don't forget to initialize the value with dummy data to avoid uninitialized errors.

export class ModelService {
    constructor() {
      this.mode = new Model();

      this._http.get('/api/v1/cats')
      .map(res => res.json())
      .subscribe(
        json => {
          this.model = new Model(json);
        },
        error => console.log(error);
      );
    }
}

This assumes Model, is a data model representing the structure of your data.

Model with no parameters should create a new instance with all values initialized (but empty). That way, if the template renders before the data is received it won't throw an error.

Ideally, if you want to persist the data to avoid unnecessary http requests you should put this in an object that has its own observer that you can subscribe to.

Use a service to achieve this:

MyApp.app.service("xxxSvc", function () {

var _xxx = {};

return {
    getXxx: function () {
        return _xxx;
    },
    setXxx: function (value) {
        _xxx = value;
    }
};

});

Next, inject this service into both controllers.

In Controller1, you would need to set the shared xxx value with a call to the service: xxxSvc.setXxx(xxx)

Finally, in Controller2, add a $watch on this service's getXxx() function like so:

  $scope.$watch(function () { return xxxSvc.getXxx(); }, function (newValue, oldValue) {
        if (newValue != null) {
            //update Controller2's xxx value
            $scope.xxx= newValue;
        }
    }, true);

I had the same doubt, but see the PHP docu:

https://www.php.net/manual/en/function.file-exists.php

https://www.php.net/manual/en/function.is-dir.php

You will see that is_dir() has both properties.

Return Values is_dir Returns TRUE if the filename exists and is a directory, FALSE otherwise.

If you don't want to commit, or want to commit later (commit message will still be prepared for you, which you can also edit):

git revert -n <commit>

You can also use org.apache.commons.lang.ArrayUtils.isEquals()

The accepted answer still threw a Javascript error in IE for me (for Angular 1.2 at least). It is a bug but the workaround is to use ngAttr detailed on https://docs.angularjs.org/guide/interpolation

<input type="text" ng-model="inputText" ng-attr-placeholder="{{somePlaceholder}}" />

Issue: https://github.com/angular/angular.js/issues/5025

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

Use a Profiler

Your approach will work nevertheless, but if you are looking for more sophisticated approaches. I'd suggest using a C# Profiler.

The advantages they have is:

• You can even get a statement level breakup
• No changes required in your codebase
• Instrumentions generally have very less overhead, hence very accurate results can be obtained.

There are many available open-source as well.

In the right hand column under your solution explorer, you can see next to the reference to "Science" its marked as a warning. Either that means it cant find it, or its objecting to it for some other reason. While this is the case and your code requires it (and its not just in the references list) it wont compile.

Please post the warning message, we can try help you further.

Just check if response[0] is undefined:

if(response[0] !== undefined) { ... }

If you still need to explicitly check the title, do so after the initial check:

if(response[0] !== undefined && response[0].title !== undefined){ ... }

Do you override .ToString() on all of your objects that are in the properties? Otherwise, that second comparison could come back with null.

Also, in that second comparison, I'm on the fence about the construct of !( A == B) compared to (A != B), in terms of readability six months/two years from now. The line itself is pretty wide, which is ok if you've got a wide monitor, but might not print out very well. (nitpick)

Are all of your objects always using properties such that this code will work? Could there be some internal, non-propertied data that could be different from one object to another, but all exposed data is the same? I'm thinking of some data which could change over time, like two random number generators that happen to hit the same number at one point, but are going to produce two different sequences of information, or just any data that doesn't get exposed through the property interface.

An example of an IF Statement that can be used to add a calculation into the cell you wish to hide if value = 0 but displayed upon another cell value reference.

=IF(/Your reference cell/=0,"",SUM(/Here you put your SUM/))

$sql = "SELECT count(id) as value FROM your_table WHERE your_field = ?";
$your_count = $this->db->query($sql, array($your_field))->row(0)->value;
echo $your_count;

Boolean types are defined in documentation:
http://docs.python.org/library/stdtypes.html#boolean-values

Quoted from doc:

Boolean values are the two constant objects False and True. They are used to represent truth values (although other values can also be considered false or true). In numeric contexts (for example when used as the argument to an arithmetic operator), they behave like the integers 0 and 1, respectively. The built-in function bool() can be used to cast any value to a Boolean, if the value can be interpreted as a truth value (see section Truth Value Testing above).

They are written as False and True, respectively.

So in java code remove braces, change true to True and you will be ok :)

You can add events to objects when you create them. If you are adding the same events to multiple objects at different times, creating a named function might be the way to go.

var mouseOverHandler = function() {
    // Do stuff
};
var mouseOutHandler = function () {
    // Do stuff
};

$(function() {
    // On the document load, apply to existing elements
    $('select').hover(mouseOverHandler, mouseOutHandler);
});

// This next part would be in the callback from your Ajax call
$("<select></select>")
    .append( /* Your <option>s */ )
    .hover(mouseOverHandler, mouseOutHandler)
    .appendTo( /* Wherever you need the select box */ )
;

You can use IN operator as below

select * from dbo.books where isbn IN
(select isbn from dbo.lending where lended_date between @fdate and @tdate)

Your best bet would be to anticipate prefixes, so:

"(|(displayName=SEARCHKEY*)(displayName=ITSM - SEARCHKEY*)(displayName=alt prefix - SEARCHKEY*))"

Clunky, but I'm doing a similar thing within my organization.

I know I'm super late regarding this topic but there's this easy to use library where you can easily get the version numbers of Worpress, PHP, Apache, and MySQL, all-in-one.

It is called the Wordpress Environment (W18T) library

\r is used to point to the start of a line and can replace the text from there, e.g.

main()
{
printf("\nab");
printf("\bsi");
printf("\rha");
}

Produces this output:

hai

\n is for new line.

I had this problem before, and solved it according to React official page isMounted is an Antipattern.

Set a property isMounted flag to be true in componentDidMount , and toggle it false in componentWillUnmount. When you setState() in your callbacks, check isMounted first! It works for me.

state = {
    isMounted: false
  }
  componentDidMount() {
      this.setState({isMounted: true})
  }
  componentWillUnmount(){
      this.setState({isMounted: false})
  }

callback:

if (this.state.isMounted) {
 this.setState({'time': remainTimeInfo});}

You can also get the colors from your resources by using:

dateView.setDivider(new ColorDrawable(_context.getResources().getColor(R.color.textlight)));
dateView.setDividerHeight(1);

1. npm install --save-dev "cross-env" module.
2. modify the code as cross-env NODE_ENV=development node foo.js. Then you can run the like npm run build.

In TortoiseSVN you can configure the proxy server under Settings=> Network

Maven

The Answer by Bhesh Gurung is correct… unless your NetBeans project is Maven based.

Dependency

Under Maven, you add a "dependency". A dependency is a description of a library (its name & version number) you want to use from your code.

Or a dependency could be a description of a library which another library needs ("depends on"). Maven automatically handles this chain, libraries that need other libraries that then need other libraries and so on. For the mathematical-minded, perhaps the phrase "Maven resolves the transitive dependencies" makes sense.

Repository

Maven gets this related-ness information, and the libraries themselves from a Maven repository. A repository is basically an online database and collection of download files (the dependency library).

Easy to Use

Adding a dependency to a Maven-based project is really quite easy. That is the whole point to Maven, to make managing dependent libraries easy and to make building them into your project easy. To get started with adding a dependency, see this Question, Adding dependencies in Maven Netbeans and my Answer with screenshot.

Are you running into this in IE only? If so, try adding this to the FIRST line of your page's HEAD tag:

<meta http-equiv="X-UA-Compatible" content="IE=7" />

I had though that all compatibility issues were fixed in later jQueries, but I ran into this one today.

I had the same error when trying to install on my Mac (using Python 2.7). A similar solution to the one I'm giving here also seemed to work for Python 3 on Windows 8.1 according to a different answer on this page by Yash Kumar Verma

Solution

Step 1: go to The URL of the TensorFlow Python package section of the TensorFlow installation page and copy the URL of the relevant link for your Python installation.

Step 2: open a terminal/command prompt and run the following command:
pip install --upgrade [paste copied url link here]

So for me it was the following:
pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.2.0-py2-none-any.whl

Update (July 21 2017): I tried this with some others who were running on Windows machines with Python 3.6 and they had to change the line in Step 2 to: python -m pip install [paste copied url link here]

Update (26 July 2018): For Python 3.6.2 (not 3.7 because it's in 3.6.2 in TF Documentation), you can also use pip3 install --upgrade [paste copied URL here] in Step 2.

Arrays in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here).

Instead, use a List:

ArrayList<String> mylist = new ArrayList<String>();
mylist.add(mystring); //this adds an element to the list.

Of course, if you know beforehand how many strings you are going to put in your array, you can create an array of that size and set the elements by using the correct position:

String[] myarray = new String[numberofstrings];
myarray[23] = string24; //this sets the 24'th (first index is 0) element to string24.

This solution worked for me:

var rawBodySaver = function (req, res, buf, encoding) {
  if (buf && buf.length) {
    req.rawBody = buf.toString(encoding || 'utf8');
  }
}

app.use(bodyParser.json({ verify: rawBodySaver }));
app.use(bodyParser.urlencoded({ verify: rawBodySaver, extended: true }));
app.use(bodyParser.raw({ verify: rawBodySaver, type: '*/*' }));

When I use solution with req.on('data', function(chunk) { }); it not working on chunked request body.

If you want all the CSS thats on your webpage in your IFrame, try this:

var headClone, iFrameHead;

// Create a clone of the web-page head
headClone = $('head').clone();

// Find the head of the the iFrame we are looking for
iFrameHead = $('#iframe').contents().find('head');

// Replace 'iFrameHead with your Web page 'head'
iFrameHead.replaceWith(headClone);

// You should now have all the Web page CSS in the Iframe

Good Luck.

As Mikkel posted before Collections.rotate is a simple way. I'm using this method for moving items up- and downward in a List.

public static <T> void moveItem(int sourceIndex, int targetIndex, List<T> list) {
    if (sourceIndex <= targetIndex) {
        Collections.rotate(list.subList(sourceIndex, targetIndex + 1), -1);
    } else {
        Collections.rotate(list.subList(targetIndex, sourceIndex + 1), 1);
    }
}

This could also be an issue of port 80 being used by "Web Deployment Agent Service". you can stop it from administrative tools->services and free up that port. as shown here

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

\s is a meta character that covers all white space. You don't need to make it case-insensitive — white space doesn't have case.

Sorting on two date fields and a numeric field example:

var generic_date =  new Date(2070, 1, 1);
checkDate = function(date) {
  return Date.parse(date) ? new Date(date): generic_date;
}

function sortData() {  
  data.sort(function(a,b){
    var deltaEnd = checkDate(b.end) - checkDate(a.end);
    if(deltaEnd) return deltaEnd;

    var deltaRank = a.rank - b.rank;
    if (deltaRank) return deltaRank;

    var deltaStart = checkDate(b.start) - checkDate(a.start);
    if(deltaStart) return deltaStart;

    return 0;
  });
}

The problem with using height:100% is that it will be 100% of the page instead of 100% of the window (as you would probably expect it to be). This will cause the problem that you're seeing, because the non-fixed content is long enough to include the fixed content with 100% height without requiring a scroll bar. The browser doesn't know/care that you can't actually scroll that bar down to see it

You can use fixed to accomplish what you're trying to do.

.fixed-content {
    top: 0;
    bottom:0;
    position:fixed;
    overflow-y:scroll;
    overflow-x:hidden;
}

This fork of your fiddle shows my fix: http://jsfiddle.net/strider820/84AsW/1/

Because the question is not always supposed to be understood as the fastest technical way - I always suggest the most straightforward fastest way to understand/write: a list comprehension, one-liner

[i for i in list_from_which_to_search if i in list_to_search_in]

I had a list_to_search_in with all the items, and wanted to return the indexes of the items in the list_from_which_to_search.

This returns the indexes in a nice list.

There are other ways to check this problem - however list comprehensions are quick enough, adding to the fact of writing it quick enough, to solve a problem.

A less verbose approach:

int number = [dict[@"integer"] intValue];

you can use it directly with $scope instance

     $scope.init=function()
        {
            console.log("entered");
            data={};
            /*do whatever you want such as initialising scope variable,
              using $http instance etcc..*/
        }
       //simple call init function on controller
       $scope.init();

Here are two implementations of itertools.combinations

One that returns a list

def combinations(lst, depth, start=0, items=[]):
    if depth <= 0:
        return [items]
    out = []
    for i in range(start, len(lst)):
        out += combinations(lst, depth - 1, i + 1, items + [lst[i]])
    return out

One returns a generator

def combinations(lst, depth, start=0, prepend=[]):
    if depth <= 0:
        yield prepend
    else:
        for i in range(start, len(lst)):
            for c in combinations(lst, depth - 1, i + 1, prepend + [lst[i]]):
                yield c

Please note that providing a helper function to those is advised because the prepend argument is static and is not changing with every call

print([c for c in combinations([1, 2, 3, 4], 3)])
# [[1, 2, 3], [1, 2, 4], [1, 3, 4], [2, 3, 4]]

# get a hold of prepend
prepend = [c for c in combinations([], -1)][0]
prepend.append(None)

print([c for c in combinations([1, 2, 3, 4], 3)])
# [[None, 1, 2, 3], [None, 1, 2, 4], [None, 1, 3, 4], [None, 2, 3, 4]]

This is a very superficial case but better be safe than sorry

I got it:

string clean = Regex.Replace(q, @"[^a-zA-Z0-9\s]", string.Empty);

Didn't know you could put \s in the brackets

{
    return str.Length <= maxLength ? str : str.Remove(maxLength);
}

I researched on the internet and some answers includes enabling the "access for lesser app" and "unlocking gmail captcha" which sadly didn't work for me until I found the 2-step verification.

What I did the following was:

1. enable the 2-step verification to google HERE

2. Create App Password to be use by your system HERE

3. I selected Others (custom name) and clicked generate

4. Went to my env file in laravel and edited this

   [email protected]

   MAIL_PASSWORD=thepasswordgenerated

5. Restarted my apache server and boom! It works again.

This was my solution. I created this to atleast make other people not go wasting their time researching for a possible answer.

foreach (array('one', 'two', 'three') as $v) {
    switch ($v) {
        case (function ($v) {
            if ($v == 'two') return $v;
            return 'one';
        })($v):
            echo "$v min \n";
            break;


    }
}

You could override it or preferably extend it's implementation like this

parseFloat = (function(_super) {
    return function() {
        // Extend it to log the value for example that is passed
        console.log(arguments[0]);
        // Or override it by always subtracting 1 for example
        arguments[0] = arguments[0] - 1;
        return _super.apply(this, arguments);
    };         

})(parseFloat);

And call it as you would normally call it:

var result = parseFloat(1.345); // It should log the value 1.345 but get the value 0.345

i suspect that your default date format is different than the scripts default settigns. test your script with the 'dateformat' option

$( "#datepicker" ).datepicker({ 
    dateFormat: 'dd-mm-yy'
});

instead of dd-mm-yy, your desired format

No way to do this that I know of, although I'm very curious to read if anyone has a good answer. I have been thinking about adding something like this to one of the apps my company builds, but have found no good way to do it.

The one thing I can think of (although not directly on point) is that I believe you can limit the total memory usage for a COM+ application in Windows. It would require the app to be written to run in COM+, of course, but it's the closest way I know of.

The working set stuff is good (Job Objects also control working sets), but that's not total memory usage, only real memory usage (paged in) at any one time. It may work for what you want, but afaik it doesn't limit total allocated memory.

Here use asp:CompareValidator, and compare the value to "select" option.

Use Operator="NotEqual" ValueToCompare="0" to prevent the user from submitting the "select".

<asp:CompareValidator ControlToValidate="ddlReportType" ID="CompareValidator1"
    ValidationGroup="g1" CssClass="errormesg" ErrorMessage="Please select a type"
    runat="server" Display="Dynamic" 
    Operator="NotEqual" ValueToCompare="0" Type="Integer" />

When you do above, if you select the "select " option from dropdown it will show the ErrorMessage.

• Guava: Google using classes Resources, Files

  static Charset charset = com.google.common.base.Charsets.UTF_8;
  public static String guava_ServerFile( URL url ) throws IOException {
      return Resources.toString( url, charset );
  }
  public static String guava_DiskFile( File file ) throws IOException {

• Java 8 BufferReader using Stream API

  public static String streamURL_Buffer( URL url ) throws IOException {
      java.io.InputStream source = url.openStream();
      BufferedReader reader = new BufferedReader( new InputStreamReader( source ) );

      BufferedReader reader = new BufferedReader( new FileReader( file ) );
      return reader.lines().collect(Collectors.joining(System.lineSeparator()));
  }
  

• Scanner Class with regex \A. which matches the beginning of input.

  static String charsetName = java.nio.charset.StandardCharsets.UTF_8.toString();
  public static String streamURL_Scanner( URL url ) throws IOException {
      java.io.InputStream source = url.openStream();

• Ways to convert an InputStream to a String

Navigate to /tomcat-root/conf folder. Within you will find the server.xml file.

Open the server.xml in your preferred editor. Search the below similar statement (not exactly same as below will differ)

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

Going to give the port number to 9090

     <Connector port="9090" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Save the file and restart the server. Now the tomcat will listen at port 9090

I like overriding jQuery widgets.

(function ($) {
    $.widget("sauti.dialog", $.ui.dialog, {
        options: {
            headerVisible: false
        },
        _create: function () {
            // ready to generate button
            this._super("_create"); // for 18 would be $.Widget.prototype._create.call(this);
            // decide if header is visible
            if(this.options.headerVisible == false)
                this.uiDialogTitlebar.hide();
        },
        _setOption: function (key, value) {
            this._super(key, value); // for 1.8 would be $.Widget.prototype._setOption.apply( this, arguments );
            if (key === "headerVisible") {
                if (key == false)
                    this.uiDialogTitlebar.hide();
                else
                    this.uiDialogTitlebar.show();
                return;
            }
        }
    });
})(jQuery);

So you can now setup if you want to show title bar or not

   $('#mydialog').dialog({
      headerVisible: false // or true
});

According to the API, the headers can all be passed in using requests.get:

import requests
r=requests.get("http://www.example.com/", headers={"content-type":"text"})

You can't do that in JavaScript, since JS is executed in the browser, not in the server, so it didn't know anything about directories or other server resources.

The best option is using a server side script like the one posted by jellyfishtree.

Scenario / Solution 1:
Ensure your Folder / Sub-folder is not in the .gitignore file, by any chance.

Scenario / Solution 2:
By default, git add . works recursively.

Scenario / Solution 3:
git add --all :/ works smoothly, where git add . doesn't (work).
(@JasonHartley's comment)

Scenario / Solution 4:
The issue I personally faced was adding Subfolders or Files, which were common between multiple Folders.

For example:
Folder/Subfolder-L1/Subfolder-L2/...file12.txt
Folder/Subfolder-L1/Subfolder-L2/Subfolder-L3/...file123.txt
Folder/Subfolder-L1/...file1.txt

So Git was recommending me to add git submodule, which I tried but was a pain.

Finally what worked for me was:

1. git add one file that's at the last end / level of a Folder.
For example:
git add Folder/Subfolder-L1/Subfolder-L2/Subfolder-L3/...file123.txt

2. git add --all :/ now.
It'll very swiftly add all the Folders, Subfolders and files.

Piece of cake!

<SCRIPT LANGUAGE="JavaScript" SRC="/clock.js"></SCRIPT>

C didn't use to have consts, so #defines were the only way of providing constant values. Both C and C++ do have them now, so there is no point in using them, except when they are going to be tested with #ifdef/ifndef.

The constructor needs to be like a factory method and return what you want. If you need additional methods/properties, you can add them to the object before returning it.

function NotImplementedError(message) { return new Error("Not implemented", message); }

x = new NotImplementedError();

Though I'm not sure why you'd need to do this. Why not just use new Error... ? Custom exceptions don't really add much in JavaScript (or probably any untyped language).

To unzip all files in a directory just type this cmd in terminal:

unzip '*.zip'

You could find disk intensive full table scans with something like this:

   SQL_FullText SQLFullText 
FROM

   SELECT Disk_Reads, Executions, SQL_ID, LTRIM(SQL_Text) SQL_Text, 
      SQL_FullText, Operation, Options, 
      Row_Number() OVER 
         (Partition By sql_text ORDER BY Disk_Reads * Executions DESC) 
         KeepHighSQL
   FROM
   (
       SELECT Avg(Disk_Reads) OVER (Partition By sql_text) Disk_Reads, 
          Max(Executions) OVER (Partition By sql_text) Executions, 
          t.SQL_ID, sql_text, sql_fulltext, p.operation,p.options
       FROM v$sql t, v$sql_plan p
       WHERE t.hash_value=p.hash_value AND p.operation='TABLE ACCESS' 
       AND p.options='FULL' AND p.object_owner NOT IN ('SYS','SYSTEM')
       AND t.Executions > 1
   ) 
   ORDER BY DISK_READS * EXECUTIONS DESC
)

AND rownum <=5;
