It looks like the 'flush' answer will work for some, but not all cases. I needed not just to flush the values in the database, but to recreate the tables properly. I'm not using migrations yet (early days) so I really needed to drop all the tables.

Two ways I've found to drop all tables, both require something other than core django.

If you're on Heroku, drop all the tables with pg:reset:

heroku pg:reset DATABASE_URL
heroku run python manage.py syncdb

If you can install Django Extensions, it has a way to do a complete reset:

python ./manage.py reset_db --router=default

I would also highly recommend the SnowsPenultimateNormalityTest in the TeachingDemos package. The documentation of the function is far more useful to you than the test itself, though. Read it thoroughly before using the test.

I don't recommend the use of this to remember the two:

My use case: I am going to the city.

includes -> drive the car

extends -> fill the petrol

I would rather you use: My use case: I am going to the city.

extends -> driving the car

includes -> fill the petrol

Am taught that extend relationship continues the behaviour of a base class. The base class functionalities have to be there. The include relationship on the other hand, are akin to functions that may be called. May is in bold.

This can be seen from agilemodeling Reuse in Use-Case Models

Try this code:

String strProc =
         "DECLARE \n" +
         "   sys_date DATE;"+
         "" +
         "BEGIN\n" +
         "" +
         "   SELECT SYSDATE INTO sys_date FROM dual;\n" +
         "" +
         "END;\n";

try{
    DriverManager.registerDriver ( new oracle.jdbc.driver.OracleDriver () );
    Connection connection = DriverManager.getConnection ("jdbc:oracle:thin:@your_db_IP:1521:your_db_SID","user","password");  
    PreparedStatement psProcToexecute = connection.prepareStatement(strProc);
    psProcToexecute.execute();
}catch (Exception e) {
    System.out.println(e.toString());  
}

Try replacing your last line of gulpfile.js

gulp.task('default', ['server', 'watch']);

with

gulp.task('default', gulp.series('server', 'watch'));

I may be late but actual code for react-create-app for react > 16 ver. After each change state is saved in sessionStorage (not localStorage) and is crypted via crypto-js. On refresh (when user demands refresh of the page by clicking refresh button) state is loaded from the storage. I also recommend not to use sourceMaps in build to avoid readablility of the key phrases.

my index.js

import React from "react";
import ReactDOM from "react-dom";
import './index.css';
import App from './containers/App';
import * as serviceWorker from './serviceWorker';
import {createStore} from "redux";
import {Provider} from "react-redux"
import {BrowserRouter} from "react-router-dom";
import rootReducer from "./reducers/rootReducer";
import CryptoJS from 'crypto-js';

const key = CryptoJS.enc.Utf8.parse("someRandomText_encryptionPhase");
const iv = CryptoJS.enc.Utf8.parse("someRandomIV");
const persistedState = loadFromSessionStorage();

let store = createStore(rootReducer, persistedState,
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__());

function loadFromSessionStorage() {
    try {
        const serializedState = sessionStorage.getItem('state');
        if (serializedState === null) {
            return undefined;
        }
        const decrypted = CryptoJS.AES.decrypt(serializedState, key, {iv: iv}).toString(CryptoJS.enc.Utf8);
        return JSON.parse(decrypted);
    } catch {
        return undefined;
    }
}

function saveToSessionStorage(state) {
        try {
            const serializedState = JSON.stringify(state);
            const encrypted = CryptoJS.AES.encrypt(serializedState, key, {iv: iv});
            sessionStorage.setItem('state', encrypted)
        } catch (e) {
            console.log(e)
        }
}

ReactDOM.render(
    <BrowserRouter>
        <Provider store={store}>
            <App/>
        </Provider>
    </BrowserRouter>,
    document.getElementById('root')
);

store.subscribe(() => saveToSessionStorage(store.getState()));

serviceWorker.unregister();

When getting "File not found", my problem was that there was no symlink in the folder where was pointing this line in ngix config:

root /var/www/claims/web;

I was facing this problem while trying to compile OpenCV 3 on a Xubuntu 14.04 Thrusty Tahr system. With all the dev packages of Python installed, the configuration process was always returning the message:

Could NOT found PythonInterp: /usr/bin/python2.7 (found suitable version "2.7.6", minimum required is "2.7")
Could NOT find PythonLibs (missing: PYTHON_INCLUDE_DIRS) (found suitable exact version "2.7.6")
Found PythonInterp: /usr/bin/python3.4 (found suitable version "3.4", minimum required is "3.4")
Could NOT find PythonLibs (missing: PYTHON_LIBRARIES) (Required is exact version "3.4.0")

The CMake version available on Thrusty Tahr repositories is 2.8. Some posts inspired me to upgrade CMake. I've added a PPA CMake repository which installs CMake version 3.2.

After the upgrade everything ran smoothly and the compilation was successful.

    public void invokeShare(Activity activity, String quote, String credit) {
    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, activity.getString(R.string.share_subject));
    shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Example text");    
    shareIntent.putExtra("com.facebook.platform.extra.APPLICATION_ID", activity.getString(R.string.app_id));                        
    activity.startActivity(Intent.createChooser(shareIntent, activity.getString(R.string.share_title)));
}

I used it as a callback in an event handler. When I raise the event, I pass in a method taking a string a parameter. This is what the raising of the event looks like:

SpecialRequest(this,
    new BalieEventArgs 
    { 
            Message = "A Message", 
            Action = UpdateMethod, 
            Data = someDataObject 
    });

The Method:

   public void UpdateMethod(string SpecialCode){ }

The is the class declaration of the event Args:

public class MyEventArgs : EventArgs
    {
        public string Message;
        public object Data;
        public Action<String> Action;
    }

This way I can call the method passed from the event handler with a some parameter to update the data. I use this to request some information from the user.

Just write this simple line of code :-

button.performClick();

where button is the reference variable of Button class and defined as follows:-

private Button buttonToday ;
buttonToday = (Button) findViewById(R.id.buttonToday);

That's it.

A really simple solution is to edit /etc/phpmyadmin/config.inc.php and put

$cfg['Servers'][$i]['table_uiprefs'] = '';

It just manages the UI and who needs the UI if its interfering with display of actual data.

cheers

Now that most people use Kotlin instead of Java, here is the code in Kotlin for converting a bitmap into a base64 string.

import java.io.ByteArrayOutputStream

private fun encodeImage(bm: Bitmap): String? {
        val baos = ByteArrayOutputStream()
        bm.compress(Bitmap.CompressFormat.JPEG, 100, baos)
        val b = baos.toByteArray()
        return Base64.encodeToString(b, Base64.DEFAULT)
    }

AFAIK, the only way is to use

 

If you can use CSS then you can use padding or margin. See Box model, and for Internet Explorer, also read Internet Explorer box model bug.

you are calling a script file not a command so you have to use -file eg :

powershell -executionPolicy bypass -noexit -file "c:\temp\test.ps1" "c:\test with space"

for PS V2

powershell.exe -noexit &'c:\my scripts\test.ps1'

(check bottom of this technet page http://technet.microsoft.com/en-us/library/ee176949.aspx )

My version for kotlin looks like the following:

PreferenceManager.getDefaultSharedPreferences(this).apply {
        // Check if we need to display our OnboardingSupportFragment
        if (!getBoolean("wasAppStartedPreviously", false)) {
            // The user hasn't seen the OnboardingSupportFragment yet, so show it
            startActivity(Intent(this@SplashScreenActivity, AppIntroActivity::class.java))
        } else {
            startActivity(Intent(this@SplashScreenActivity, MainActivity::class.java))
        }
    }

Using the deployment profiles introduced in VS 2012, you can publish with the following command line:

msbuild MyProject.csproj /p:DeployOnBuild=true /p:PublishProfile=<profile-name> /p:Password=<insert-password> /p:VisualStudioVersion=11.0

For more information on the parameters see this.

The values for the /p:VisualStudioVersion parameter depend on your version of Visual Studio. Wikipedia has a table of Visual Studio releases and their versions.

I have fixed this issue by logging in using Xorg. By default, I have used Wayland. It looks like Wayland eliminates most of the design flaws of the Xorg it has its own issues.

I was facing similar problem on Windows 7 x64 professional edition. Please note following steps to fix this problem.

1. tools.jar is missing from required path if you are using jdk1.7 x64 bit version.

2. Please install x86 version of jdk1.7

3. Set JDK_HOME="C:\Program Files (x86)\Java\jdk1.7.0_67" and update path environment variable as path="C:\Program Files (x86)\Java\jdk1.7.0_67\bin" Note: Linux put the proper path.

4. Launch 32 bit application from /android-studio\bin folder.

I tested and verified these steps on windows 7 with 32 bit jdk1.7

try this package, works wonders, and was made for date/time...

library(lubridate)
Portfolio$Date2 <- mdy(Portfolio.all$Date2)

Try with this:

long abc=convertString2Hex("1A2A3B");

private  long  convertString2Hex(String numberHexString)
{
    char[] ChaArray = numberHexString.toCharArray();
    long HexSum=0;
    long cChar =0;

    for(int i=0;i<numberHexString.length();i++ )
    {
        if( (ChaArray[i]>='0') && (ChaArray[i]<='9') )
            cChar = ChaArray[i] - '0';
        else
            cChar = ChaArray[i]-'A'+10;
        HexSum = 16 * HexSum + cChar;
    }
    return  HexSum;
}

As the previous answers exhaustively covered the theory behind the value categories, there is just another thing I'd like to add: you can actually play with it and test it.

For some hands-on experimentation with the value categories, you can make use of the decltype specifier. Its behavior explicitly distinguishes between the three primary value categories (xvalue, lvalue, and prvalue).

Using the preprocessor saves us some typing ...

Primary categories:

#define IS_XVALUE(X) std::is_rvalue_reference<decltype((X))>::value
#define IS_LVALUE(X) std::is_lvalue_reference<decltype((X))>::value
#define IS_PRVALUE(X) !std::is_reference<decltype((X))>::value

Mixed categories:

#define IS_GLVALUE(X) (IS_LVALUE(X) || IS_XVALUE(X))
#define IS_RVALUE(X) (IS_PRVALUE(X) || IS_XVALUE(X))

Now we can reproduce (almost) all the examples from cppreference on value category.

Here are some examples with C++17 (for terse static_assert):

void doesNothing(){}
struct S
{
    int x{0};
};
int x = 1;
int y = 2;
S s;

static_assert(IS_LVALUE(x));
static_assert(IS_LVALUE(x+=y));
static_assert(IS_LVALUE("Hello world!"));
static_assert(IS_LVALUE(++x));

static_assert(IS_PRVALUE(1));
static_assert(IS_PRVALUE(x++));
static_assert(IS_PRVALUE(static_cast<double>(x)));
static_assert(IS_PRVALUE(std::string{}));
static_assert(IS_PRVALUE(throw std::exception()));
static_assert(IS_PRVALUE(doesNothing()));

static_assert(IS_XVALUE(std::move(s)));
// The next one doesn't work in gcc 8.2 but in gcc 9.1. Clang 7.0.0 and msvc 19.16 are doing fine.
static_assert(IS_XVALUE(S().x)); 

The mixed categories are kind of boring once you figured out the primary category.

For some more examples (and experimentation), check out the following link on compiler explorer. Don't bother reading the assembly, though. I added a lot of compilers just to make sure it works across all the common compilers.

This rule

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o producer.o consumer.o AddRemove.o

is wrong. It says to create a file named producer.o (with -o producer.o), but you want to create a file named main. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET:

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o $@ producer.o consumer.o AddRemove.o

As Shahbaz rightly points out, the gmake professionals would also use $^ which expands to all the prerequisites in the rule. In general, if you find yourself repeating a string or name, you're doing it wrong and should use a variable, whether one of the built-ins or one you create.

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o $@ $^

Here is one way to “untrack” any files that are would otherwise be ignored under the current set of exclude patterns:

(GIT_INDEX_FILE=some-non-existent-file \
git ls-files --exclude-standard --others --directory --ignored -z) |
xargs -0 git rm --cached -r --ignore-unmatch --

This leaves the files in your working directory but removes them from the index.

The trick used here is to provide a non-existent index file to git ls-files so that it thinks there are no tracked files. The shell code above asks for all the files that would be ignored if the index were empty and then removes them from the actual index with git rm.

After the files have been “untracked”, use git status to verify that nothing important was removed (if so adjust your exclude patterns and use git reset -- path to restore the removed index entry). Then make a new commit that leaves out the “crud”.

The “crud” will still be in any old commits. You can use git filter-branch to produce clean versions of the old commits if you really need a clean history (n.b. using git filter-branch will “rewrite history”, so it should not be undertaken lightly if you have any collaborators that have pulled any of your historical commits after the “crud” was first introduced).

First, you cannot achieve this without using a client side capability. This is where the javascript runs.

Secondly, if you are trying to control what an end user can consume from your site, then you need to rethink how you display that information. An image has a public url that can be fetched via HTTP without the need for a browser.

Authentication can control who has access to what resources.

Embedded watermarking in images can prove that the image was from a specific person/company.

At the end of the day, resource management is really user/guest managment.

The first rule of the Internet, if you dont want it taken, dont make it public!

The second rule of the Internet, if you dont want it taken, dont put it on the Internet!

I don't understand how to apply your solution :( – kalmanIsAGameChanger

Working with Arduino Sketch, I had a function causing my warnings.

Original function: char StrContains(char *str, char *sfind)

To stop the warnings I added the const in front of the char *str and the char *sfind.

Modified: char StrContains(const char *str, const char *sfind).

All warnings went away.

Basically your code is okay, thats the right way to do this. Anyhow, there are some misunderstandings:

1. fetchUserData.cfm does not contain key/value pairs. So it doesn't make sense to address keys in mData. Just use mData[index]

2. dataTables expects some more info from your serverside. At least you should tell datatables how many items in total are on your serverside and how many are filtered. I just hardcoded this info to your data. You should get the right values from counts in your server sided script.

   {
    "iTotalRecords":"6",
    "iTotalDisplayRecords":"6",
     "aaData": [
   [
       "1",
       "sameek",
       "sam",
       "sam",
       "[email protected]",
       "1",
       ""
   ],...
   

3. If you have the column names already set in the html part, you don't need to add sTitle.

4. The mRender Function takes three parameters:

   • data = The data for this cell, as defined in mData
   • type = The datatype (can be ignored mostly)
   • full = The full data array for this row.

So your mRender function should look like this:

  "mRender": function(data, type, full) {
    return '<a class="btn btn-info btn-sm" href=#/' + full[0] + '>' + 'Edit' + '</a>';
  }

Setting isBodyHtml to true allows you to use HTML tags in the message body:

msg = new MailMessage("[email protected]",
                "[email protected]", "Message from PSSP System",
                "This email sent by the PSSP system<br />" +
                "<b>this is bold text!</b>");

msg.IsBodyHtml = true;

Mongo dump and restore with uri to local

mongodump --uri "mongodb://USERNAME:PASSWORD@IP_OR_URL:PORT/DB_NAME" --collection COLLECTION_NAME -o LOCAL_URL

Omitting --collection COLLECTION_NAME will dump entire DB.

If you are using Boost 1.65 or higher, you can use boost::stacktrace:

#include <boost/stacktrace.hpp>

// ... somewhere inside the bar(int) function that is called recursively:
std::cout << boost::stacktrace::stacktrace();

There are 4 methods you can use:

1. DISTINCT
2. GROUP BY
3. Subquery
4. Common Table Expression (CTE) with ROW_NUMBER()

Consider the following sample TABLE with test data:

/** Create test table */
CREATE TEMPORARY TABLE dupes(word text, num int, id int);

/** Add test data with duplicates */
INSERT INTO dupes(word, num, id)
VALUES ('aaa', 100, 1)
      ,('bbb', 200, 2)
      ,('ccc', 300, 3)
      ,('bbb', 400, 4)
      ,('bbb', 200, 5)     -- duplicate
      ,('ccc', 300, 6)     -- duplicate
      ,('ddd', 400, 7)
      ,('bbb', 400, 8)     -- duplicate
      ,('aaa', 100, 9)     -- duplicate
      ,('ccc', 300, 10);   -- duplicate

Option 1: SELECT DISTINCT

This is the most simple and straight forward, but also the most limited way:

SELECT DISTINCT word, num 
FROM    dupes
ORDER BY word, num;

/*
word|num|
----|---|
aaa |100|
bbb |200|
bbb |400|
ccc |300|
ddd |400|
*/

Option 2: GROUP BY

Grouping allows you to add aggregated data, like the min(id), max(id), count(*), etc:

SELECT  word, num, min(id), max(id), count(*)
FROM    dupes
GROUP BY word, num
ORDER BY word, num;

/*
word|num|min|max|count|
----|---|---|---|-----|
aaa |100|  1|  9|    2|
bbb |200|  2|  5|    2|
bbb |400|  4|  8|    2|
ccc |300|  3| 10|    3|
ddd |400|  7|  7|    1|
*/

Option 3: Subquery

Using a subquery, you can first identify the duplicate rows to ignore, and then filter them out in the outer query with the WHERE NOT IN (subquery) construct:

/** Find the higher id values of duplicates, distinct only added for clarity */
    SELECT  distinct d2.id
    FROM    dupes d1
        INNER JOIN dupes d2 ON d2.word=d1.word AND d2.num=d1.num
    WHERE d2.id > d1.id

/*
id|
--|
 5|
 6|
 8|
 9|
10|
*/

/** Use the previous query in a subquery to exclude the dupliates with higher id values */
SELECT  *
FROM    dupes
WHERE   id NOT IN (
    SELECT  d2.id
    FROM    dupes d1
        INNER JOIN dupes d2 ON d2.word=d1.word AND d2.num=d1.num
    WHERE d2.id > d1.id
)
ORDER BY word, num;

/*
word|num|id|
----|---|--|
aaa |100| 1|
bbb |200| 2|
bbb |400| 4|
ccc |300| 3|
ddd |400| 7|
*/

Option 4: Common Table Expression with ROW_NUMBER()

In the Common Table Expression (CTE), select the ROW_NUMBER(), partitioned by the group column and ordered in the desired order. Then SELECT only the records that have ROW_NUMBER() = 1:

WITH CTE AS (
    SELECT  *
           ,row_number() OVER(PARTITION BY word, num ORDER BY id) AS row_num
    FROM    dupes
)
SELECT  word, num, id 
FROM    cte
WHERE   row_num = 1
ORDER BY word, num;

/*
word|num|id|
----|---|--|
aaa |100| 1|
bbb |200| 2|
bbb |400| 4|
ccc |300| 3|
ddd |400| 7|
*/

SELECT (column name) FROM (table name) WHERE (column name) < DATEADD(Day,-30,GETDATE());

Example.

SELECT `name`, `phone`, `product` FROM `tbmMember` WHERE `dateofServicw` < (Day,-30,GETDATE()); 

You might want to use Scanner to parse through and find the specific sections you want to modify. There's also Split and StringTokenizer that may work, but at the level you're working at Scanner might be what's needed.

Here's some additional info on what the difference is between them: Scanner vs. StringTokenizer vs. String.Split

You should put your model class before create_all() call, like this:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, username, email):
        self.username = username
        self.email = email

    def __repr__(self):
        return '<User %r>' % self.username

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

If your models are declared in a separate module, import them before calling create_all().

Say, the User model is in a file called models.py,

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

# See important note below
from models import User

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

Important note: It is important that you import your models after initializing the db object since, in your models.py _you also need to import the db object from this module.

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

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

Quoting from Conda: Myths and Misconceptions (a comprehensive description):

...

Myth #3: Conda and pip are direct competitors

Reality: Conda and pip serve different purposes, and only directly compete in a small subset of tasks: namely installing Python packages in isolated environments.

Pip, which stands for Pip Installs Packages, is Python's officially-sanctioned package manager, and is most commonly used to install packages published on the Python Package Index (PyPI). Both pip and PyPI are governed and supported by the Python Packaging Authority (PyPA).

In short, pip is a general-purpose manager for Python packages; conda is a language-agnostic cross-platform environment manager. For the user, the most salient distinction is probably this: pip installs python packages within any environment; conda installs any package within conda environments. If all you are doing is installing Python packages within an isolated environment, conda and pip+virtualenv are mostly interchangeable, modulo some difference in dependency handling and package availability. By isolated environment I mean a conda-env or virtualenv, in which you can install packages without modifying your system Python installation.

Even setting aside Myth #2, if we focus on just installation of Python packages, conda and pip serve different audiences and different purposes. If you want to, say, manage Python packages within an existing system Python installation, conda can't help you: by design, it can only install packages within conda environments. If you want to, say, work with the many Python packages which rely on external dependencies (NumPy, SciPy, and Matplotlib are common examples), while tracking those dependencies in a meaningful way, pip can't help you: by design, it manages Python packages and only Python packages.

Conda and pip are not competitors, but rather tools focused on different groups of users and patterns of use.

For those who need save objects like {foo: 'bar'}, I share my edited version of @KevinBurke's answer. I've added JSON.stringify and JSON.parse, that's all.

cookie = {

    set: function (name, value, days) {
        if (days) {
            var date = new Date();
            date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
            var expires = "; expires=" + date.toGMTString();
        }
        else
            var expires = "";
        document.cookie = name + "=" + JSON.stringify(value) + expires + "; path=/";
    },

    get : function(name){
        var nameEQ = name + "=",
            ca = document.cookie.split(';');

        for(var i=0;i < ca.length;i++) {
          var c = ca[i];
          while (c.charAt(0)==' ') c = c.substring(1,c.length);
            if (c.indexOf(nameEQ) == 0) 
              return  JSON.parse(c.substring(nameEQ.length,c.length));
        }

        return null;
    }

}

So, now you can do things like this:

cookie.set('cookie_key', {foo: 'bar'}, 30);

cookie.get('cookie_key'); // {foo: 'bar'}

cookie.set('cookie_key', 'baz', 30);

cookie.get('cookie_key'); // 'baz'

What files are you importing into the files getting the R error?

My understanding of the R file are that they are automatically generated reference lists to all attributes within the Android app. Therefore, you can't change it yourself.

Are you using Eclipse to build this project? Were the older projects getting these errors made before updating Eclipse? What are the references that are getting errors?

Check to make sure that you've not imported another R file from other copied code in another app.

Use JQuery. You need to set-up a click event on your button which will toggle the visibility of your wizard div.

$('#btn').click(function() {
    $('#wizard').toggle();
});

Refer to the JQuery website for more information.

This can also be done without JQuery. Using only standard JavaScript:

<script type="text/javascript">
   function toggle_visibility(id) {
       var e = document.getElementById(id);
       if(e.style.display == 'block')
          e.style.display = 'none';
       else
          e.style.display = 'block';
   }
</script>

Then add onclick="toggle_visibility('id_of_element_to_toggle');" to the button that is used to show and hide the div.

I was searching to get a result for this either and I ended up with;

const MyObject = {
    SubObject: {
        'eu': [0, "asd", true, undefined],
        'us': [0, "asd", false, null],
        'aus': [0, "asd", false, 0]
    }
};

For those who wanted the result as a string:

Object.keys(MyObject.SubObject).toString()

output: "eu,us,aus"

For those who wanted the result as an array:

Array.from(Object.keys(MyObject))

output: Array ["eu", "us", "aus"]

For those who are looking for a "contains" type method: as numeric result:

console.log(Object.keys(MyObject.SubObject).indexOf("k"));

output: -1

console.log(Object.keys(MyObject.SubObject).indexOf("eu"));

output: 0

console.log(Object.keys(MyObject.SubObject).indexOf("us"));

output: 3

as boolean result:

console.log(Object.keys(MyObject.SubObject).includes("eu"));

output: true

In your case;

var myVar = { typeA: { option1: "one", option2: "two" } }_x000D_
_x000D_
    // Example 1_x000D_
    console.log(Object.keys(myVar.typeA).toString()); // Result: "option1, option2"_x000D_
_x000D_
    // Example 2_x000D_
    console.log(Array.from(Object.keys(myVar.typeA))); // Result: Array ["option1", "option2" ]_x000D_
    _x000D_
    // Example 3 as numeric_x000D_
    console.log((Object.keys(myVar.typeA).indexOf("option1")>=0)?'Exist!':'Does not exist!'); // Result: Exist!_x000D_
    _x000D_
    // Example 3 as boolean_x000D_
    console.log(Object.keys(myVar.typeA).includes("option2")); // Result: True!_x000D_
    _x000D_
    // if you would like to know about SubObjects_x000D_
    for(var key in myVar){_x000D_
      // do smt with SubObject_x000D_
      console.log(key); // Result: typeA_x000D_
    }_x000D_
_x000D_
    // if you already know your "SubObject"_x000D_
    for(var key in myVar.typeA){_x000D_
      // do smt with option1, option2_x000D_
      console.log(key); // Result: option1 // Result: option2_x000D_
    }

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

You can install and use the pip-autoremove utility to remove a package plus unused dependencies.

# install pip-autoremove
pip install pip-autoremove
# remove "somepackage" plus its dependencies:
pip-autoremove somepackage -y

980 is not the "defacto standard", you'll generally see most people targeting a size a little bit less than 1024px wide to account for browser chrome such as scrollbars, etc.

Usually people target between 960 and 990px wide. Often people use a grid system (like 960.gs) which is opinionated about what the default width should be.

Also note, just recently the most common screen size now averages quite a bit bigger than 1024px wide, ranking in at 1366px wide. See http://techcrunch.com/2012/04/11/move-over-1024x768-the-most-popular-screen-resolution-on-the-web-is-now-1366x768/

I had the same problem. My project layout looked like

\---super
    \---thirdparty
        +---mod1-root
        |   +---mod1-linux32
        |   \---mod1-win32
        \---mod2-root
            +---mod2-linux32
            \---mod2-win32

In my case, I had a mistake in my pom.xmls at the modX-root-level. I had copied the mod1-root tree and named it mod2-root. I incorrectly thought I had updated all the pom.xmls appropriately; but in fact, mod2-root/pom.xml had the same group and artifact ids as mod1-root/pom.xml. After correcting mod2-root's pom.xml to have mod2-root specific maven coordinates my issue was resolved.

One technique I utilize is to redirect output to an ASCII file using the Out-File cmdlet.

For example, I often run SQL scripts that create another SQL script to execute in Oracle. With simple redirection (">"), the output will be in UTF-16 which is not recognized by SQLPlus. To work around this:

sqlplus -s / as sysdba "@create_sql_script.sql" |
Out-File -FilePath new_script.sql -Encoding ASCII -Force

The generated script can then be executed via another SQLPlus session without any Unicode worries:

sqlplus / as sysdba "@new_script.sql" |
tee new_script.log

An IDE is an integrated development environment - a suped-up text editor with additional support for developing (such as forms designers, resource editors, etc), compiling and debugging applications. e.g Eclipse, Visual Studio.

A Library is a chunk of code that you can call from your own code, to help you do things more quickly/easily. For example, a Bitmap Processing library will provide facilities for loading and manipulating bitmap images, saving you having to write all that code for yourself. Typically a library will only offer one area of functionality (processing images or operating on zip files)

An API (application programming interface) is a term meaning the functions/methods in a library that you can call to ask it to do things for you - the interface to the library.

An SDK (software development kit) is a library or group of libraries (often with extra tool applications, data files and sample code) that aid you in developing code that uses a particular system (e.g. extension code for using features of an operating system (Windows SDK), drawing 3D graphics via a particular system (DirectX SDK), writing add-ins to extend other applications (Office SDK), or writing code to make a device like an Arduino or a mobile phone do what you want). An SDK will still usually have a single focus.

A toolkit is like an SDK - it's a group of tools (and often code libraries) that you can use to make it easier to access a device or system... Though perhaps with more focus on providing tools and applications than on just code libraries.

A framework is a big library or group of libraries that provides many services (rather than perhaps only one focussed ability as most libraries/SDKs do). For example, .NET provides an application framework - it makes it easier to use most (if not all) of the disparate services you need (e.g. Windows, graphics, printing, communications, etc) to write a vast range of applications - so one "library" provides support for pretty much everything you need to do. Often a framework supplies a complete base on which you build your own code, rather than you building an application that consumes library code to do parts of its work.

There are of course many examples in the wild that won't exactly match these descriptions though.

Maybe consider an "INSTEAD OF" trigger and do the check yourself? With a non-clustered (non-unique) index on the column to enable the lookup.

I got a version based on what I saw previously. It helped me a lot to create export files as CSV or TXT. I'm storing a table into a ## Temp Table:

    IF OBJECT_ID('tempdb..##TmpExportFile') IS NOT NULL
DROP TABLE ##TmpExportFile;


DECLARE @columnHeader VARCHAR(8000)
DECLARE @raw_sql nvarchar(3000)

SELECT
              * INTO ##TmpExportFile
              ------ FROM THE TABLE RESULTS YOU WANT TO GET
              ------ COULD BE A TABLE OR A TEMP TABLE BASED ON INNER JOINS
              ------ ,ETC.

FROM TableName -- optional WHERE ....


DECLARE @table_name  VARCHAR(50) = '##TmpExportFile'
SELECT
              @columnHeader = COALESCE(@columnHeader + ',', '') + '''[' + c.name + ']''' + ' as ' + '' + c.name + ''
FROM tempdb.sys.columns c
INNER JOIN tempdb.sys.tables t
              ON c.object_id = t.object_id
WHERE t.NAME = @table_name

print @columnheader

                DECLARE @ColumnList VARCHAR(max)
SELECT
              @ColumnList = COALESCE(@ColumnList + ',', '') + 'CAST([' + c.name + '] AS CHAR(' + LTRIM(STR(max_length)) + '))'
FROM tempdb.sys.columns c
INNER JOIN tempdb.sys.tables t
              ON c.object_id = t.object_id
WHERE t.name = @table_name
print @ColumnList

--- CSV FORMAT                                       
SELECT
              @raw_sql = 'bcp "SELECT ' + @columnHeader + ' UNION all SELECT ' + @ColumnList + ' FROM ' + @table_name + ' " queryout \\networkdrive\networkfolder\datafile.csv -c -t, /S' + ' SQLserverName /T'
--PRINT @raw_sql
EXEC xp_cmdshell @raw_sql

  --- TXT FORMAT
       SET @raw_sql = 'bcp "SELECT ' + @columnHeader + ' UNION all SELECT ' + @ColumnList + ' FROM ' + @table_name + ' " queryout \\networkdrive\networkfolder\MISD\datafile.txt /c /S'+ ' SQLserverName /T'
       EXEC xp_cmdshell @raw_sql



DROP TABLE ##TmpExportFile

Avoid using companion objects. Behind the hood, getter and setter instance methods are created for the fields to be accessible. Calling instance methods is technically more expensive than calling static methods.

public class DbConstants {
    companion object {
        val TABLE_USER_ATTRIBUTE_EMPID = "_id"
        val TABLE_USER_ATTRIBUTE_DATA = "data"
    }

Instead define the constants in object.

Recommended practice :

object DbConstants {
        const val TABLE_USER_ATTRIBUTE_EMPID = "_id"
        const val TABLE_USER_ATTRIBUTE_DATA = "data"
}

and access them globally like this: DbConstants.TABLE_USER_ATTRIBUTE_EMPID

A very elegant way is to use ng-controller to run a single controller outside of the ng-view:

<div class="collapse navbar-collapse" ng-controller="HeaderController">
    <ul class="nav navbar-nav">
        <li ng-class="{ active: isActive('/')}"><a href="/">Home</a></li>
        <li ng-class="{ active: isActive('/dogs')}"><a href="/dogs">Dogs</a></li>
        <li ng-class="{ active: isActive('/cats')}"><a href="/cats">Cats</a></li>
    </ul>
</div>
<div ng-view></div>

and include in controllers.js:

function HeaderController($scope, $location) 
{ 
    $scope.isActive = function (viewLocation) { 
        return viewLocation === $location.path();
    };
}

Using parameters in batch files: %0 and %9

Batch files can refer to the words passed in as parameters with the tokens: %0 to %9.

%0 is the program name as it was called.
%1 is the first command line parameter
%2 is the second command line parameter
and so on till %9.

parameters passed in on the commandline must be alphanumeric characters and delimited by spaces. Since %0 is the program name as it was called, in DOS %0 will be empty for AUTOEXEC.BAT if started at boot time.

Example:

Put the following command in a batch file called mybatch.bat:

@echo off
@echo hello %1 %2
pause

Invoking the batch file like this: mybatch john billy would output:

hello john billy

Get more than 9 parameters for a batch file, use: %*

The Percent Star token %* means "the rest of the parameters". You can use a for loop to grab them, as defined here:

http://www.robvanderwoude.com/parameters.php

Notes about delimiters for batch parameters

Some characters in the command line parameters are ignored by batch files, depending on the DOS version, whether they are "escaped" or not, and often depending on their location in the command line:

commas (",") are replaced by spaces, unless they are part of a string in 
double quotes

semicolons (";") are replaced by spaces, unless they are part of a string in 
double quotes

"=" characters are sometimes replaced by spaces, not if they are part of a 
string in double quotes

the first forward slash ("/") is replaced by a space only if it immediately 
follows the command, without a leading space

multiple spaces are replaced by a single space, unless they are part of a 
string in double quotes

tabs are replaced by a single space

leading spaces before the first command line argument are ignored

<meta http-equiv="refresh" content="5; url=http://example.com/">

1. Create a folder in sdcard :

adb shell "su 0 mkdir /sdcard/com.test"

2. Move your files to the new folder :

adb shell "su 0 mv -F /data/data/com.test/files/ /sdcard/com.test/"

3. You can now use adb pull :

adb pull /sdcard/com.test

#div {
    top: 50%;
    left: 50%;
    position:fixed;
}

just set the above three properties any of your element and there you Go!

Your div is exactly at the center of the screen

Push annotated tags, keep lightweight local

man git-tag says:

Annotated tags are meant for release while lightweight tags are meant for private or temporary object labels.

And certain behaviors do differentiate between them in ways that this recommendation is useful e.g.:

• annotated tags can contain a message, creator, and date different than the commit they point to. So you could use them to describe a release without making a release commit.

  Lightweight tags don't have that extra information, and don't need it, since you are only going to use it yourself to develop.

• git push --follow-tags will only push annotated tags
• git describe without command line options only sees annotated tags

Internals differences

• both lightweight and annotated tags are a file under .git/refs/tags that contains a SHA-1

• for lightweight tags, the SHA-1 points directly to a commit:

  git tag light
  cat .git/refs/tags/light
  

  prints the same as the HEAD's SHA-1.

  So no wonder they cannot contain any other metadata.

• annotated tags point to a tag object in the object database.

  git tag -as -m msg annot
  cat .git/refs/tags/annot
  

  contains the SHA of the annotated tag object:

  c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  and then we can get its content with:

  git cat-file -p c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  sample output:

  object 4284c41353e51a07e4ed4192ad2e9eaada9c059f
  type commit
  tag annot
  tagger Ciro Santilli <[email protected]> 1411478848 +0200
  
  msg
  -----BEGIN PGP SIGNATURE-----
  Version: GnuPG v1.4.11 (GNU/Linux)
  
  <YOUR PGP SIGNATURE>
  -----END PGP SIGNAT
  

  And this is how it contains extra metadata. As we can see from the output, the metadata fields are:

  • the object it points to
  • the type of object it points to. Yes, tag objects can point to any other type of object like blobs, not just commits.
  • the name of the tag
  • tagger identity and timestamp
  • message. Note how the PGP signature is just appended to the message

  A more detailed analysis of the format is present at: What is the format of a git tag object and how to calculate its SHA?

Bonuses

• Determine if a tag is annotated:

  git cat-file -t tag
  

  Outputs

  • commit for lightweight, since there is no tag object, it points directly to the commit
  • tag for annotated, since there is a tag object in that case

• List only lightweight tags: How can I list all lightweight tags?

I think os.environ.copy() is better if you don't intend to modify the os.environ for the current process:

import subprocess, os
my_env = os.environ.copy()
my_env["PATH"] = "/usr/sbin:/sbin:" + my_env["PATH"]
subprocess.Popen(my_command, env=my_env)

Using the answers above, I created a quick static method that can easily be re-used. It only aims at tinting the progress color for the activated stars. The stars that are not activated remain grey.

    public static RatingBar tintRatingBar (RatingBar ratingBar, int progressColor)if (ratingBar.getProgressDrawable() instanceof LayerDrawable) {
        LayerDrawable progressDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
        Drawable drawable = progressDrawable.getDrawable(2);
        Drawable compat = DrawableCompat.wrap(drawable);
        DrawableCompat.setTint(compat, progressColor);
        Drawable[] drawables = new Drawable[3];
        drawables[2] = compat;

        drawables[0] = progressDrawable.getDrawable(0);
        drawables[1] = progressDrawable.getDrawable(1);

        LayerDrawable layerDrawable = new LayerDrawable(drawables);

        ratingBar.setProgressDrawable(layerDrawable);

        return ratingBar;
    }
    else {
        Drawable progressDrawable =  ratingBar.getProgressDrawable();
        Drawable compat = DrawableCompat.wrap(progressDrawable);
        DrawableCompat.setTint(compat, progressColor);
        ratingBar.setProgressDrawable(compat);
        return ratingBar;
    }
}

Just pass your rating bar and a Color using getResources().getColor(R.color.my_rating_color)

As you can see, I use DrawableCompat so it's backward compatible.

EDIT : This method does not work on API21 (go figure why). You end up with a NullPointerException when calling setProgressBar. I ended up disabling the whole method on API >= 21.

For API >= 21, I use SupperPuccio solution.

I don't know about expanding the information bar.

But you can get the timings set as a default for all queries showing in the "Messages" tab.

When in a Query window, go to the Query Menu item, select "query options" then select "advanced" in the "Execution" group and check the "set statistics time" / "set statistics IO" check boxes. These values will then show up in the messages area for each query without having to remember to put in the set stats on and off.

You could also use Shift + Alt + S to enable client statistics at any time

VAR=$(scan)

Exactly the same way as for programs.

You can add .a file in the linking command:

  gcc yourfiles /path/to/library/libLIBRARY.a

But this is not talking with gcc driver, but with ld linker as options like -Wl,anything are.

When you tell gcc or ld -Ldir -lLIBRARY, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose). To change order of library types checked you can use -Wl,-Bstatic and -Wl,-Bdynamic. Here is a man page of gnu LD: http://linux.die.net/man/1/ld

To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:

gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3

Assuming that default setting of ld is to use dynamic libraries (it is on Linux).

Using this.props.children is the idiomatic way to pass instantiated components to a react component

const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>

When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div or span):

const Label = props => <span>{props.children}</span>
const Button = props => {
    const Inner = props.inner; // Note: variable name _must_ start with a capital letter 
    return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>

If what you want to do is to pass a children-like parameter as a prop, you can do that:

const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />

After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.

The operators || and && are called conditional operators, while | and & are called bitwise operators. They serve different purposes.

Conditional operators works only with expressions that statically evaluate to boolean on both left- and right-hand sides.

Bitwise operators works with any numeric operands.

If you want to perform a logical comparison, you should use conditional operators, since you will add some kind of type safety to your code.

what have you tried? it's very simple:

String s = "/abc/def/ghfj.doc";
s.substring(s.lastIndexOf("/") + 1)

You can run several copies of your script in parallel, each copy for different input data, e.g. to process all *.cfg files on 4 cores:

    ls *.cfg | xargs -P 4 -n 1 read_cfg.sh

The read_cfg.sh script takes just one parameters (as enforced by -n)

Its wrong to do that in refer to referential integrity, because once its broken its not easy to turn it on again without having to go through the records and delete the ones which breaks the constraints.

Anyway the Syntax is as follows:

ALTER TABLE Tablename DROP CONSTRAINT ContName;

You can use plt.rcParams["font.size"] for setting font_size in matplotlib and also you can use plt.rcParams["font.family"] for setting font_family in matplotlib. Try this example:

import matplotlib.pyplot as plt
plt.style.use('seaborn-whitegrid')

label = [1,2,3,4,5,6,7,8]
x = [0.001906,0.000571308,0.0020305,0.0037422,0.0047095,0.000846667,0.000819,0.000907]
y = [0.2943301,0.047778308,0.048003167,0.1770876,0.532489833,0.024611333,0.157498667,0.0272095]


plt.ylabel('eigen centrality')
plt.xlabel('betweenness centrality')
plt.text(0.001906, 0.2943301, '1 ', ha='right', va='center')
plt.text(0.000571308, 0.047778308, '2 ', ha='right', va='center')
plt.text(0.0020305, 0.048003167, '3 ', ha='right', va='center')
plt.text(0.0037422, 0.1770876, '4 ', ha='right', va='center')
plt.text(0.0047095, 0.532489833, '5 ', ha='right', va='center')
plt.text(0.000846667, 0.024611333, '6 ', ha='right', va='center')
plt.text(0.000819, 0.157498667, '7 ', ha='right', va='center')
plt.text(0.000907, 0.0272095, '8 ', ha='right', va='center')
plt.rcParams["font.family"] = "Times New Roman"
plt.rcParams["font.size"] = "50"
plt.plot(x, y, 'o', color='blue')

I add the region option and everything works then fine for me:

aws ecr get-login --no-include-email --region eu-west-3

you have error in your code unexpected token.use:

  $('#purpose').on('change', function () {
   if (this.value == '1') {
    $("#business").show();
    } else {
    $("#business").hide();
   }

   });

Demo

Update: You can narrow down the code using .toggle()

 $('#purpose').on('change', function () {
   $("#business").toggle(this.value == '1');
 });

List<EmailParameterClass> parameterList = new List<EmailParameterClass>{param1, param2, param3...};

parameterList = parameterList.Where(param => param != null).ToList();

Alternatively, if you just want to convert one particular row to uppercase, use the code below:

df[[1]] <- toupper(df[[1]])

How to post file using an object in memory (like a JSON object):

import axios from 'axios';
import * as FormData  from 'form-data'

async function sendData(jsonData){
    // const payload = JSON.stringify({ hello: 'world'});
    const payload = JSON.stringify(jsonData);
    const bufferObject = Buffer.from(payload, 'utf-8');
    const file = new FormData();

    file.append('upload_file', bufferObject, "b.json");

    const response = await axios.post(
        lovelyURL,
        file,
        headers: file.getHeaders()
    ).toPromise();


    console.log(response?.data);
}

I saw another question on just this topic recently (streaming pdf into iframe using dataurl only works in chrome).

I've constructed pdfs in the ast and streamed them to the browser. I was creating them first with fdf, then with a pdf class I wrote myself - in each case the pdf was created from data retrieved from a COM object based on a couple of of GET params passed in via the url.

From looking at your data sent recieved in the ajax call, it looks like you're nearly there. I haven't played with the code for a couple of years now and didn't document it as well as I'd have cared to, but - I think all you need to do is set the target of an iframe to be the url you get the pdf from. Though this may not work - the file that oututs the pdf may also have to outut a html response header first.

In a nutshell, this is the output code I used:

//We send to a browser
header('Content-Type: application/pdf');
if(headers_sent())
    $this->Error('Some data has already been output, can\'t send PDF file');
header('Content-Length: '.strlen($this->buffer));
header('Content-Disposition: inline; filename="'.$name.'"');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
ini_set('zlib.output_compression','0');
echo $this->buffer;

So, without seeing the full response text fro the ajax call I can't really be certain what it is, though I'm inclined to think that the code that outputs the pdf you're requesting may only be doig the equivalent of the last line in the above code. If it's code you have control over, I'd try setting the headers - then this way the browser can just deal with the response text - you don't have to bother doing a thing to it.

I simply constructed a url for the pdf I wanted (a timetable) then created a string that represented the html for an iframe of the desired sie, id etc that used the constructed url as it's src. As soon as I set the inner html of a div to the constructed html string, the browser asked for the pdf and then displayed it when it was received.

function  showPdfTt(studentId)
{
    var url, tgt;
    title = byId("popupTitle");
    title.innerHTML = "Timetable for " + studentId;
    tgt = byId("popupContent");
    url = "pdftimetable.php?";
    url += "id="+studentId;
    url += "&type=Student";
    tgt.innerHTML = "<iframe onload=\"centerElem(byId('box'))\" src='"+url+"' width=\"700px\" height=\"500px\"></iframe>";
}

EDIT: forgot to mention - you can send binary pdf's in this manner. The streams they contain don't need to be ascii85 or hex encoded. I used flate on all the streams in the pdf and it worked fine.

This is old but as it is the first result in Google,

Please note that this also happens when your MySql service is down,

I fixed this by simply restarting MySQL Server using:

/etc/init.d/mysql restart

in SSH (Command is for a CentOS/CPanel server)

The Java Language Specification, section 15.10, states:

An array creation expression creates an object that is a new array whose elements are of the type specified by the PrimitiveType or ClassOrInterfaceType. It is a compile-time error if the ClassOrInterfaceType does not denote a reifiable type (§4.7).

and

The rules above imply that the element type in an array creation expression cannot be a parameterized type, other than an unbounded wildcard.

The closest you can do is use an unchecked cast, either from the raw type, as you have done, or from an unbounded wildcard:

 HashMap<String, String>[] responseArray = (Map<String, String>[]) new HashMap<?,?>[games.size()];

Your version is clearly better :-)

Adding to the answer of stackoverflowuser2010, in the general case you can just use

data = np.array([[1,1,1],[2,2,2],[3,3,3]])

vector = np.array([1,2,3])

data / vector.reshape(-1,1)

This will turn your vector into a column matrix/vector. Allowing you to do the elementwise operations as you wish. At least to me, this is the most intuitive way going about it and since (in most cases) numpy will just use a view of the same internal memory for the reshaping it's efficient too.

To update records, you need to write changes to .mdb file on disk. If your web/shared application can't write to disk, you can't update existing or add new records. So, enable read/write access in database folder or move database to other folder where your application has write permission....for more detail please check:

http://www.beansoftware.com/ASP.NET-FAQ/Operation-Must-Use-An-Updateable-Query.aspx

You can use css:

 style="margin-left: 5px;"

If you open the php.ini file in wamp, you will find these two lines:

smtp_server
smtp_port

Add the server and port number for your host (you may need to contact them for details)

The following two lines don't exist:

auth_username
auth_password

So you will need to add them to be able to send mail from a server that requires authentication. So an example may be:

smtp_server = mail.example.com
smtp_port = 26
auth_username = [email protected]
auth_password = example_password

You'd be much better off using the same array with both lists, and creating angular filters to achieve your goal.

http://docs.angularjs.org/guide/dev_guide.templates.filters.creating_filters

Rough, untested code follows:

appModule.filter('checked', function() {
    return function(input, checked) {
        if(!input)return input;
        var output = []
        for (i in input){
            var item = input[i];
            if(item.checked == checked)output.push(item);
        }
        return output
    }
});

and the view (i added an "uncheck" button too)

<div id="AddItem">
     <h3>Add Item</h3>

    <input value="1" type="number" placeholder="1" ng-model="itemAmount">
    <input value="" type="text" placeholder="Name of Item" ng-model="itemName">
    <br/>
    <button ng-click="addItem()">Add to list</button>
</div>
<!-- begin: LIST OF CHECKED ITEMS -->
<div id="CheckedList">
     <h3>Checked Items: {{getTotalCheckedItems()}}</h3>

     <h4>Checked:</h4>

    <table>
        <tr ng-repeat="item in items | checked:true" class="item-checked">
            <td><b>amount:</b> {{item.amount}} -</td>
            <td><b>name:</b> {{item.name}} -</td>
            <td> 
               <i>this item is checked!</i>
               <button ng-click="item.checked = false">uncheck item</button>

            </td>
        </tr>
    </table>
</div>
<!-- end: LIST OF CHECKED ITEMS -->
<!-- begin: LIST OF UNCHECKED ITEMS -->
<div id="UncheckedList">
     <h3>Unchecked Items: {{getTotalItems()}}</h3>

     <h4>Unchecked:</h4>

    <table>
        <tr ng-repeat="item in items | checked:false" class="item-unchecked">
            <td><b>amount:</b> {{item.amount}} -</td>
            <td><b>name:</b> {{item.name}} -</td>
            <td>
                <button ng-click="item.checked = true">check item</button>
            </td>
        </tr>
    </table>
</div>
<!-- end: LIST OF ITEMS -->

Then you dont need the toggle methods etc in your controller

It does not sound like you imported the library right especially when you say at the point Add the library to your application project: I felt lost .. basically because I don't have the "add" option by itself .. however I clicked on "add library" and moved on ..

in eclipse you need to right click on the project, go to Properties, select Android in the list then Add to add the library

follow this tutorial in the docs

There is a better way to write polar(), here it is:

Here is an article with live working demo Class Animation In JQuery

You can try this,

$(function () {
   $("#btnSubmit").click(function () {
   $("#btnClass").removeClass("btnDiv").addClass("btn");
   });
});

you can also use switchClass() method - it allows you to animate the transition of adding and removing classes at the same time.

$(function () {
        $("#btnSubmit").click(function () {
            $("#btnClass").switchClass("btn", "btnReset", 1000, "easeInOutQuad");
        });
    });

A nice complete solution that keeps a map of your class labels:

labels = features['col1'].unique()
labels_dict = dict(zip(labels, range(len(labels))))
features = features.replace({"col1": labels_dict})

This way, you can at any point refer to the original class label from labels_dict.

Adding @WebAppConfiguration (org.springframework.test.context.web.WebAppConfiguration) annotation to your DemoApplicationTests class will work.

I agree with Charles Duffy that a proper XML parser is the right way to go.

But as to what's wrong with your sed command (or did you do it on purpose?).

• $data was not quoted, so $data is subject to shell's word splitting, filename expansion among other things. One of the consequences being that the spacing in the XML snippet is not preserved.

So given your specific XML structure, this modified sed command should work

title=$(sed -ne '/title/{s/.*<title>\(.*\)<\/title>.*/\1/p;q;}' <<< "$data")

Basically for the line that contains title, extract the text between the tags, then quit (so you don't extract the 2nd <title>)

You can use jquery-validate.js . The following is the code snippet from jquery-validate.js.

// ajax mode: abort
// usage: $.ajax({ mode: "abort"[, port: "uniqueport"]});
// if mode:"abort" is used, the previous request on that port (port can be undefined) is aborted via XMLHttpRequest.abort()

var pendingRequests = {},
    ajax;
// Use a prefilter if available (1.5+)
if ( $.ajaxPrefilter ) {
    $.ajaxPrefilter(function( settings, _, xhr ) {
        var port = settings.port;
        if ( settings.mode === "abort" ) {
            if ( pendingRequests[port] ) {
                pendingRequests[port].abort();
            }
            pendingRequests[port] = xhr;
        }
    });
} else {
    // Proxy ajax
    ajax = $.ajax;
    $.ajax = function( settings ) {
        var mode = ( "mode" in settings ? settings : $.ajaxSettings ).mode,
            port = ( "port" in settings ? settings : $.ajaxSettings ).port;
        if ( mode === "abort" ) {
            if ( pendingRequests[port] ) {
                pendingRequests[port].abort();
            }
            pendingRequests[port] = ajax.apply(this, arguments);
            return pendingRequests[port];
        }
        return ajax.apply(this, arguments);
    };
}

So that you just only need to set the parameter mode to abort when you are making ajax request.

Couldn't you just add it as an environment variable in Jenkins settings:

Manage Jenkins -> Global properties > Environment variables: And then click "Add" to add a property PATH and its value to what you need.

I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

SELECT wpoi.order_id As No_Commande
FROM  wp_woocommerce_order_items AS wpoi
LEFT JOIN wp_postmeta AS wpp ON wpoi.order_id = wpp.post_id 
                            AND wpp.meta_key = '_shipping_first_name'
WHERE  wpoi.order_id =2198 

{{ }} tells the template to print the value, this won't work in expressions like you're trying to do. Instead, use the {% set %} template tag and then assign the value the same way you would in normal python code.

{% set testing = 'it worked' %}
{% set another = testing %}
{{ another }}

Result:

it worked

Here is a complete screenshot example that works with chrome in 2021. The end result is a blob ready to be transmitted. Flow is: request media > grab frame > draw to canvas > transfer to blob. If you want to do it more memory efficient explore OffscreenCanvas or possibly ImageBitmapRenderingContext

https://jsfiddle.net/v24hyd3q/1/

// Request media
navigator.mediaDevices.getDisplayMedia().then(stream => 
{
  // Grab frame from stream
  let track = stream.getVideoTracks()[0];
  let capture = new ImageCapture(track);
  capture.grabFrame().then(bitmap => 
  {
    // Stop sharing
    track.stop();
      
    // Draw the bitmap to canvas
    canvas.width = bitmap.width;
    canvas.height = bitmap.height;
    canvas.getContext('2d').drawImage(bitmap, 0, 0);
      
    // Grab blob from canvas
    canvas.toBlob(blob => {
        // Do things with blob here
        console.log('output blob:', blob);
    });
  });
})
.catch(e => console.log(e));

A more modern way is to use flexbox:

ul{_x000D_
  list-style-type:none;_x000D_
  display:flex;_x000D_
  justify-content: center;_x000D_
_x000D_

}

<div>_x000D_

To prevent this, make sure every BEGIN TRANSACTION has COMMIT

The following will say successful but will leave uncommitted transactions:

BEGIN TRANSACTION
BEGIN TRANSACTION
<SQL_CODE?
COMMIT

Closing query windows with uncommitted transactions will prompt you to commit your transactions. This will generally resolve the Error 1222 message.

I think it is the autoboxing that is throwing you off.

This part of your code:

   public static Integer inc(Integer i) {
        i = i+1;    // I think that this must be **sneakally** creating a new integer...  
        System.out.println("Inc: "+i);
        return i;
    }

Really boils down to code that looks like:

  public static Integer inc(Integer i) {
        i = new Integer(i) + new Integer(1);      
        System.out.println("Inc: "+i);
        return i;
    }

Which of course.. will not changes the reference passed in.

You could fix it with something like this

  public static void main(String[] args) {
        Integer integer = new Integer(0);
        for (int i =0; i<10; i++){
            integer = inc(integer);
            System.out.println("main: "+integer);
        }
    }

For me, simple install of certificates helped:

sudo apt-get install ca-certificates

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.

You can't add a class directly to the LIs very easily, but is there any reason not to target them in a slightly different but equally specific way (by their parent ul)?

You can set the class or ID of the menu with the menu_class and menu_id parameters (affixed to the UL parent of the LIs) and then target the li's via CSS that way, like so:

<?php wp_nav_menu('menu_id=mymenu'); ?>

And for CSS:

ul#mymenu li {
    /* your styles here */
}

Edit: At the time of writing in 2013 this was the easiest way to add it, but updates since then have added the feature to add CSS classes directly in the admin navigation editor. See more recent answers for details.

You can also have several workspaces - so you can connect to one and have set "A" of projects - and then connect to a different set when ever you like.

resourcesloader.class.getClass()

Can be broken down to:

Class<resourcesloader> clazz = resourceloader.class;
Class<Class> classClass = clazz.getClass();

Which means you're trying to load the resource using a bootstrap class.

Instead you probably want something like:

resourcesloader.class.getResource("repository/SSL-Key/cert.jks").toString()

If only javac warned about calling static methods on non-static contexts...

If you do not want to mess with what should be the primary key, I recommend:

1. Incorporate ROW_NUMBER into your selection
2. Set it as primary key
3. Set all other columns/members as non-primary in the model

You can do it with strtol, like this:

char *str = "ab234cid*(s349*(20kd", *p = str;
while (*p) { // While there are more characters to process...
    if ( isdigit(*p) || ( (*p=='-'||*p=='+') && isdigit(*(p+1)) )) {
        // Found a number
        long val = strtol(p, &p, 10); // Read number
        printf("%ld\n", val); // and print it.
    } else {
        // Otherwise, move on to the next character.
        p++;
    }
}

One reason: the literal 0 has a bad tendency to acquire the type int, e.g. in perfect argument forwarding or more in general as argument with templated type.

Another reason: readability and clarity of code.

@Jay Mooney: A generic Dictionary class in .NET is actually a hash table, just with fixed types.

The code you've shown shouldn't convince anyone to use Hashtable instead of Dictionary, since both code pieces can be used for both types.

For hashtable:

foreach(object key in h.keys)
{
     string keyAsString = key.ToString(); // btw, this is unnecessary
     string valAsString = h[key].ToString();

     System.Diagnostics.Debug.WriteLine(keyAsString + " " + valAsString);
}

For dictionary:

foreach(string key in d.keys)
{
     string valAsString = d[key].ToString();

     System.Diagnostics.Debug.WriteLine(key + " " + valAsString);
}

And just the same for the other one with KeyValuePair, just use the non-generic version for Hashtable, and the generic version for Dictionary.

So it's just as easy both ways, but Hashtable uses Object for both key and value, which means you will box all value types, and you don't have type safety, and Dictionary uses generic types and is thus better.

I think using UPDATE ... WHERE as explained here and here is a lean approach

Project.update(
      { title: 'a very different title no' } /* set attributes' value */, 
      { where: { _id : 1 }} /* where criteria */
).then(function(affectedRows) {
Project.findAll().then(function(Projects) {
     console.log(Projects) 
})

some applications will treat "localhost" specially. the mysql client will treat localhost as a request to connect to the local unix domain socket instead of using tcp to connect to the server on 127.0.0.1. This may be faster, and may be in a different authentication zone.

I don't know of other apps that treat localhost differently than 127.0.0.1, but there probably are some.

Passing data forward to the next View Controller

The following is an example based on the video. The idea is to pass a string from the text field in the First View Controller to the label in the Second View Controller.

Create the storyboard layout in the Interface Builder. To make the segue, you just Control click on the button and drag over to the Second View Controller.

First View Controller

The code for the First View Controller is

import UIKit

class FirstViewController: UIViewController {

    @IBOutlet weak var textField: UITextField!

    // This function is called before the segue
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        // Get a reference to the second view controller
        let secondViewController = segue.destination as! SecondViewController

        // Set a variable in the second view controller with the String to pass
        secondViewController.receivedString = textField.text!
    }

}

Second View Controller

And the code for the Second View Controller is

import UIKit

class SecondViewController: UIViewController {

    @IBOutlet weak var label: UILabel!

    // This variable will hold the data being passed from the First View Controller
    var receivedString = ""

    override func viewDidLoad() {
        super.viewDidLoad()

        // Used the text from the First View Controller to set the label
        label.text = receivedString
    }

}

Don't forget

• Hook up the outlets for the UITextField and the UILabel.
• Set the first and second View Controllers to the appropriate Swift files in Interface Builder.

Passing data back to the previous View Controller

To pass data back from the second view controller to the first view controller, you use a protocol and a delegate. This video is a very clear walk though of that process:

• YouTube tutorial: iOS Swift Basics Tutorial: Protocols and Delegates But also read this post to make sure you don't get into a strong reference cycle.

The following is an example based on the video (with a few modifications).

Create the storyboard layout in the Interface Builder. Again, to make the segue, you just Control drag from the button to the Second View Controller. Set the segue identifier to showSecondViewController. Also, don't forget to hook up the outlets and actions using the names in the following code.

First View Controller

The code for the First View Controller is

import UIKit

class FirstViewController: UIViewController, DataEnteredDelegate {

    @IBOutlet weak var label: UILabel!

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "showSecondViewController" {
            let secondViewController = segue.destination as! SecondViewController
            secondViewController.delegate = self
        }
    }

    func userDidEnterInformation(info: String) {
        label.text = info
    }
}

Note the use of our custom DataEnteredDelegate protocol.

Second View Controller and Protocol

The code for the second view controller is

import UIKit

// Protocol used for sending data back
protocol DataEnteredDelegate: AnyObject {
    func userDidEnterInformation(info: String)
}

class SecondViewController: UIViewController {

    // Making this a weak variable, so that it won't create a strong reference cycle
    weak var delegate: DataEnteredDelegate? = nil

    @IBOutlet weak var textField: UITextField!

    @IBAction func sendTextBackButton(sender: AnyObject) {

        // Call this method on whichever class implements our delegate protocol
        delegate?.userDidEnterInformation(info: textField.text!)

        // Go back to the previous view controller
        _ = self.navigationController?.popViewController(animated: true)
    }
}

Note that the protocol is outside of the View Controller class.

That's it. Running the app now, you should be able to send data back from the second view controller to the first.

Pekka answered my question in the comments. He didn't post an answer, so I am now. Use the exit() method after the header redirect. For some reason the rest of the code of the page continues to execute after the header() method redirect. When the rest of the code executes, the echo statement is outputted to the page. And you can't redirect using the header function after you output to the page. To avoid rest of the code from executing, use exit(). Thanks Pekka.

UPDATE: When using the web browser Internet Explorer, I have noticed that $_POST['cancel'] is not reliable. I am not exactly sure why this is, but I suspect IE posts additional variables on a form submit, specifically the variable 'cancel' is posted. I solved this by using a variable name other than 'cancel'. The combination of using exit() and a unique variable name is working for me.

Just learned about InitCap().

Here is some sample code:

SELECT ID
      ,InitCap(LastName ||', '|| FirstName ||' '|| Nvl(MiddleName,'')) AS RecipientName
FROM SomeTable

A better way to create SessionFactory object in Latest hibernate release 4.3.0 onward is as follow:

Configuration configuration = new Configuration().configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().
applySettings(configuration.getProperties());
SessionFactory factory = configuration.buildSessionFactory(builder.build());

Controls in the same cell of a Grid are rendered back-to-front. So a simple way to put one control on top of another is to put it in the same cell.

Here's a useful example, which pops up a panel that disables everything in the view (i.e. the user control) with a busy message while a long-running task is executed (i.e. while the BusyMessage bound property isn't null):

<Grid>

    <local:MyUserControl DataContext="{Binding}"/>

    <Grid>
        <Grid.Style>
            <Style TargetType="Grid">
                <Setter Property="Visibility"
                        Value="Visible" />
                <Style.Triggers>
                    <DataTrigger Binding="{Binding BusyMessage}"
                                 Value="{x:Null}">
                        <Setter Property="Visibility"
                                Value="Collapsed" />
                    </DataTrigger>

                </Style.Triggers>
            </Style>
        </Grid.Style>
        <Border HorizontalAlignment="Stretch"
                VerticalAlignment="Stretch"
                Background="DarkGray"
                Opacity=".7" />
        <Border HorizontalAlignment="Center"
                VerticalAlignment="Center"
                Background="White"
                Padding="20"
                BorderBrush="Orange"
                BorderThickness="4">
            <TextBlock Text="{Binding BusyMessage}" />
        </Border>
    </Grid>
</Grid>

Enter services.msc and shutdown anything SQL you have running. The SQL server might be taking over the port.

1. Make a jar file from your applet class and META-INF/MANIFEST.MF file.
2. Sign your jar file with your certificate.
3. Configure your local site permissions as > file:///C:/ or http: //localhost:8080
4. Then run your html document on Intenet Explorer on Windows.(Not Google Chrome !)

re.match is anchored at the beginning of the string. That has nothing to do with newlines, so it is not the same as using ^ in the pattern.

As the re.match documentation says:

If zero or more characters at the beginning of string match the regular expression pattern, return a corresponding MatchObject instance. Return None if the string does not match the pattern; note that this is different from a zero-length match.

Note: If you want to locate a match anywhere in string, use search() instead.

re.search searches the entire string, as the documentation says:

Scan through string looking for a location where the regular expression pattern produces a match, and return a corresponding MatchObject instance. Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string.

So if you need to match at the beginning of the string, or to match the entire string use match. It is faster. Otherwise use search.

The documentation has a specific section for match vs. search that also covers multiline strings:

Python offers two different primitive operations based on regular expressions: match checks for a match only at the beginning of the string, while search checks for a match anywhere in the string (this is what Perl does by default).

Note that match may differ from search even when using a regular expression beginning with '^': '^' matches only at the start of the string, or in MULTILINE mode also immediately following a newline. The “match” operation succeeds only if the pattern matches at the start of the string regardless of mode, or at the starting position given by the optional pos argument regardless of whether a newline precedes it.

Now, enough talk. Time to see some example code:

# example code:
string_with_newlines = """something
someotherthing"""

import re

print re.match('some', string_with_newlines) # matches
print re.match('someother', 
               string_with_newlines) # won't match
print re.match('^someother', string_with_newlines, 
               re.MULTILINE) # also won't match
print re.search('someother', 
                string_with_newlines) # finds something
print re.search('^someother', string_with_newlines, 
                re.MULTILINE) # also finds something

m = re.compile('thing$', re.MULTILINE)

print m.match(string_with_newlines) # no match
print m.match(string_with_newlines, pos=4) # matches
print m.search(string_with_newlines, 
               re.MULTILINE) # also matches

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

You can access the code values for the characters in your string using the ord() built-in function. If you then need to format this in binary, the string.format() method will do the job.

a = "test"
print(' '.join(format(ord(x), 'b') for x in a))

(Thanks to Ashwini Chaudhary for posting that code snippet.)

While the above code works in Python 3, this matter gets more complicated if you're assuming any encoding other than UTF-8. In Python 2, strings are byte sequences, and ASCII encoding is assumed by default. In Python 3, strings are assumed to be Unicode, and there's a separate bytes type that acts more like a Python 2 string. If you wish to assume any encoding other than UTF-8, you'll need to specify the encoding.

In Python 3, then, you can do something like this:

a = "test"
a_bytes = bytes(a, "ascii")
print(' '.join(["{0:b}".format(x) for x in a_bytes]))

The differences between UTF-8 and ascii encoding won't be obvious for simple alphanumeric strings, but will become important if you're processing text that includes characters not in the ascii character set.

I have Windows 10 64 bit, this worked for me, This solution can work for both (Anaconda/MiniConda) distributions.

1. First of all try to uninstall anaconda/miniconda which is causing problem.
2. After that delete '.anaconda' and '.conda' folders from 'C:\Users\'

3. If you have any antivirus software installed then try to exclude all the folders,subfolders inside 'C:\ProgramData\Anaconda3\' from

   • Behaviour detection.
   • Virus detection.
   • DNA scan.
   • Suspicious files scan.
   • Any other virus protection mode.

   *(Note: 'C:\ProgramData\Anaconda3' this folder is default installation folder, you can change it just replace your excluded path at installation destination prompt while installing Anaconda)*

4. Now install Anaconda with admin privileges.
   • Set the installation path as 'C:\ProgramData\Anaconda3' or you can specify your custom path just remember it should not contain any white space and it should be excluded from virus detection.
   • At Advanced Installation Options you can check "Add Anaconda to my PATH environment variable(optional)" and "Register Anaconda as my default Python 3.6"
   • Install it with further default settings. Click on finish after done.
   • Restart your computer.

Now open Command prompt or Anaconda prompt and check installation using following command

conda list

If you get any package list then the anaconda/miniconda is successfully installed.

int elem = 42;
std::vector<int> v;
v.push_back(elem);
if(std::find(v.begin(), v.end(), elem) != v.end())
{
  //elem exists in the vector
} 

This may be fairly obvious, but it tripped me up just now:

If you are taking a tail-log backup, this issue can also be caused by having this option checked in the SSMS Restore wizard - "Leave source database in the restoring state (WITH NORECOVERY)"

First, get the date in UTC -- you've already done that so this step would really just be a database call:

$timezone = "UTC";
date_default_timezone_set($timezone);

$utc = gmdate("M d Y h:i:s A");
print "UTC: " . date('r', strtotime($utc)) . "\n";

Next, set your local time zone in PHP:

$timezone = "America/Guayaquil";
date_default_timezone_set($timezone);

And now get the offset in seconds:

$offset = date('Z', strtotime($utc));
print "offset: $offset \n";

Finally, add the offset to the integer timestamp of your original datetime:

print "LOCAL: " . date('r', strtotime($utc) + $offset) . "\n";

@hai-phan's answer using LEFT JOIN is the key, but it might be a bit hard to follow. I had a complicated query that may also return nothing. I just simplified his answer to my need. It's easy to apply to query with many columns.

;WITH CTE AS (
  -- SELECT S.Id, ...
  -- FROM Sites S WHERE Id = @SiteId
  -- EXCEPT SOME CONDITION.
  -- Whatever your query is
)
SELECT CTE.* -- If you want something else instead of NULL, use COALESCE.
FROM (SELECT @SiteId AS ID) R
LEFT JOIN CTE ON CTE.Id = R.ID

Update: This answer on SqlServerCentral is the best. It utilizes this feature of MAX - "MAX returns NULL when there is no row to select."

SELECT ISNULL(MAX(value), 0) FROM table WHERE Id = @SiteId

If you haven't committed changes

If your changes are compatible with the other branch

This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.

As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:

git checkout -b branch_name
git add <files>
git commit -m "message"

If your changes are incompatible with the other branch

If you get the error:

error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches

Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:

git stash
git checkout -b branch_name
git stash pop

It will be as if you had made those changes after creating the new branch. Then you can commit as usual:

git add <files>
git commit -m "message"

If you have committed changes

If you want to keep the commits in the original branch

See the answer by Carl Norum with cherry-picking, which is the right tool in this case:

git checkout <target name>
git cherry-pick <original branch>

If you don't want to keep the commits in the original branch

See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:

git branch -f <original branch> <earlier commit id>

If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.

You can also do this.

//find the index of the CompanyName column
int columnIndex = thisReader.GetOrdinal("CompanyName"); 
//Get the value of the column. Will throw if the value is null.
string companyName = thisReader.GetString(columnIndex);

Select-Object creates a new psobject and copies the properties you requested to it. You can verify this with GetType():

PS > $a.GetType().fullname
System.DayOfWeek

PS > $b.GetType().fullname
System.Management.Automation.PSCustomObject

Here's a potential solution that will set the width of the bookType column (i.e. format of the bookTypes value) based on the longest bookTypes value.

public class Test {
    public static void main(String[] args) {
        String[] bookTypes = { "Newspaper", "Paper Back", "Hardcover book", "Electronic book", "Magazine" };
        double[] costs = { 1.0, 7.5, 10.0, 2.0, 3.0 };

        // Find length of longest bookTypes value.
        int maxLengthItem = 0;
        boolean firstValue = true;
        for (String bookType : bookTypes) {
            maxLengthItem = (firstValue) ? bookType.length() : Math.max(maxLengthItem, bookType.length());
            firstValue = false;
        }

        // Display rows of data
        for (int i = 0; i < bookTypes.length; i++) {
            // Use %6.2 instead of %.2 so that decimals line up, assuming max
            // book cost of $999.99. Change 6 to a different number if max cost
            // is different
            String format = "%d. %-" + Integer.toString(maxLengthItem) + "s \t\t $%9.2f\n";
            System.out.printf(format, i + 1, bookTypes[i], costs[i]);
        }
    }
}

Modified compman2408's code to be able to iterate through each NetworkInterfaceType.

public static string GetLocalIPv4 (NetworkInterfaceType _type) {
    string output = null;
    foreach (NetworkInterface item in NetworkInterface.GetAllNetworkInterfaces ()) {
        if (item.NetworkInterfaceType == _type && item.OperationalStatus == OperationalStatus.Up) {
            foreach (UnicastIPAddressInformation ip in item.GetIPProperties ().UnicastAddresses) {
                if (ip.Address.AddressFamily == AddressFamily.InterNetwork) {
                    output = ip.Address.ToString ();
                }
            }
        }
    }
    return output;
}

And you can call it like so:

static void Main (string[] args) {
    // Get all possible enum values:
    var nitVals = Enum.GetValues (typeof (NetworkInterfaceType)).Cast<NetworkInterfaceType> ();

    foreach (var nitVal in nitVals) {
        Console.WriteLine ($"{nitVal} => {GetLocalIPv4 (nitVal) ?? "NULL"}");
    }
}

So, I've done some work on family tree software. I think the problem you're trying to solve is that you need to be able to walk the tree without getting in infinite loops - in other words, the tree needs to be acyclical.

However, it looks like you're asserting that there is only one path between a person and one of their ancestors. That will guarantee that there are no cycles, but is too strict. Biologically speaking, descendancy is a directed acyclic graph (DAG). The case you have is certainly a degenerate case, but that type of thing happens all the time on larger trees.

For example, if you look at the 2^n ancestors you have at generation n, if there was no overlap, then you'd have more ancestors in 1000 AD than there were people alive. So, there's got to be overlap.

However, you also do tend to get cycles that are invalid, just bad data. If you're traversing the tree, then cycles must be dealt with. You can do this in each individual algorithm, or on load. I did it on load.

Finding true cycles in a tree can be done in a few ways. The wrong way is to mark every ancestor from a given individual, and when traversing, if the person you're going to step to next is already marked, then cut the link. This will sever potentially accurate relationships. The correct way to do it is to start from each individual, and mark each ancestor with the path to that individual. If the new path contains the current path as a subpath, then it's a cycle, and should be broken. You can store paths as vector<bool> (MFMF, MFFFMF, etc.) which makes the comparison and storage very fast.

There are a few other ways to detect cycles, such as sending out two iterators and seeing if they ever collide with the subset test, but I ended up using the local storage method.

Also note that you don't need to actually sever the link, you can just change it from a normal link to a 'weak' link, which isn't followed by some of your algorithms. You will also want to take care when choosing which link to mark as weak; sometimes you can figure out where the cycle should be broken by looking at birthdate information, but often you can't figure out anything because so much data is missing.

You could print the backspace character '\b' as many times as necessary to delete the line before printing the updated progress bar.

I know the question is about trailing slashes but I found this post during my search for trimming slashes (both at the tail and head of a string literal), as people would need this solution I am posting one here :

'///I am free///'.replace(/^\/+|\/+$/g, ''); // returns 'I am free'

UPDATE:

as @Stephen R mentioned in the comments, if you want to remove both slashes and backslashes both at the tail and the head of a string literal, you would write :

'\/\\/\/I am free\\///\\\\'.replace(/^[\\/]+|[\\/]+$/g, '') // returns 'I am free'

The simplest change would be something like this:

public static void main (String[] args) throws Exception {
  testconnect obj = new testconnect();
  obj.con2 = DriverManager.getConnection(obj.getConnectionUrl2());
  obj.con2.close();
}

I saw examples of thread IDs like this:

class myThread(threading.Thread):
    def __init__(self, threadID, name, counter):
        self.threadID = threadID
        ...

The threading module docs lists name attribute as well:

...

A thread has a name. 
The name can be passed to the constructor, 
and read or changed through the name attribute.

...

Thread.name

A string used for identification purposes only. 
It has no semantics. Multiple threads may
be given the same name. The initial name is set by the constructor.

The only thing that worked for me was inspired from here: https://stackoverflow.com/a/35527407/2310544

For pure dd/MM/yyyy, this worked for me, with angular 2 beta 16:

{{ myDate | date:'d'}}/{{ myDate | date:'MM'}}/{{ myDate | date:'y'}}

It's called dependency injection via constructor injection: class A gets the dependency as an argument to its constructor and saves the reference to dependent class as a private variable.

There's an interesting introduction on wikipedia.

For const-correctness I'd write:

using T = int;

class A
{
public:
  A(const T &thing) : m_thing(thing) {}
  // ...

private:
   const T &m_thing;
};

but a problem with this class is that it accepts references to temporary objects:

T t;
A a1{t};    // this is ok, but...

A a2{T()};  // ... this is BAD.

It's better to add (requires C++11 at least):

class A
{
public:
  A(const T &thing) : m_thing(thing) {}
  A(const T &&) = delete;  // prevents rvalue binding
  // ...

private:
  const T &m_thing;
};

Anyway if you change the constructor:

class A
{
public:
  A(const T *thing) : m_thing(*thing) { assert(thing); }
  // ...

private:
   const T &m_thing;
};

Also, since the constructor takes a pointer, it's clearer to users of A that they need to pay attention to the lifetime of the object they pass.

Somewhat related topics are:

• Should I prefer pointers or references in member data?
• Using reference as class members for dependencies
• GotW #88
• Forbid rvalue binding via constructor to member const reference

going off of jan's answer of shallow-copying the object, another clean implementation using map function,

High level of what this solution does: iterate through all the rows and copy the rows as valid js objects.

// function  will be used on every row returned by the query
const objectifyRawPacket = row => ({...row});

// iterate over all items and convert the raw packet row -> js object
const convertedResponse = results.map(objectifyRawPacket);

We leveraged the array map function: it will go over every item in the array, use the item as input to the function, and insert the output of the function into the array you're assigning.

more specifically on the objectifyRawPacket function: each time it's called its seeing the "{ RawDataPacket }" from the source array. These objects act a lot like normal objects - the "..." (spread) operator copies items from the array after the periods - essentially copying the items into the object it's being called in.

The parens around the spread operator on the function are necessary to implicitly return an object from an arrow function.

try something like this

 URL u = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
 InputStream in = u.openStream();

Then use it as any plain old input stream

No, TRUNCATE is all or nothing. You can do a DELETE FROM <table> WHERE <conditions> but this loses the speed advantages of TRUNCATE.

Math.Floor(123456.646 * 100) / 100 Would return 123456.64

As pointed out in Manto's answer, .utcOffset() is the preferred method as of Moment 2.9.0. This function uses the real offset from UTC, not the reverse offset (e.g., -240 for New York during DST). Offset strings like "+0400" work the same as before:

// always "2013-05-23 00:55"
moment(1369266934311).utcOffset(60).format('YYYY-MM-DD HH:mm')
moment(1369266934311).utcOffset('+0100').format('YYYY-MM-DD HH:mm')

The older .zone() as a setter was deprecated in Moment.js 2.9.0. It accepted a string containing a timezone identifier (e.g., "-0400" or "-04:00" for -4 hours) or a number representing minutes behind UTC (e.g., 240 for New York during DST).

// always "2013-05-23 00:55"
moment(1369266934311).zone(-60).format('YYYY-MM-DD HH:mm')
moment(1369266934311).zone('+0100').format('YYYY-MM-DD HH:mm')

To work with named timezones instead of numeric offsets, include Moment Timezone and use .tz() instead:

// determines the correct offset for America/Phoenix at the given moment
// always "2013-05-22 16:55"
moment(1369266934311).tz('America/Phoenix').format('YYYY-MM-DD HH:mm')

Overview of gcm: You send a request to google server from your android phone. You receive a registration id as a response. You will then have to send this registration id to the server from where you wish to send notifications to the mobile. Using this registration id you can then send notification to the device.

Answer:

1. To send a notification you send the data(message) with the registration id of the device to https://android.googleapis.com/gcm/send. (use curl in php).
2. To receive notification and registration etc, thats all you will be requiring.
3. You will have to store the registration id on the device as well as on server. If you use GCM.jar the registration id is stored in preferences. If you wish you can save it in your local database as well.

You need to add an alias for the count to your query and then use the addScalar() method as the default for list() method in Hibernate seams to be BigInteger for numeric SQL types. Here is an example:

List<Long> sqlResult = session.createSQLQuery("SELECT column AS num FROM table")
    .addScalar("num", StandardBasicTypes.LONG).list();

Just use a set. Its semantics are exactly what you want: a collection of unique items.

Technically you'll be iterating through the list twice: once to create the set, once for your actual loop. But you'd be doing just as much work or more with any other approach.

I was having the same problem and could not figure out what I was doing wrong. Turns out, the auto-complete for Android Studio was changing the text to either all caps or all lower case (depending on whether I typed in upper case or lower cast words before the auto-complete). The OS was not registering the name due to this issue and I would get the error regarding a missing permission. As stated above, ensure your permissions are labeled correctly:

Correct:

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

Incorrect:

<uses-permission android:name="ANDROID.PERMISSION.ACCESS_FINE_LOCATION" />

Incorrect:

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

Though this may seem trivial, its easy to overlook.

If there is some setting to make permissions non-case-sensitive, please add a comment with the instructions. Thank you!

You could create an installer for you EXE file by:
1. Press WinKey + R
2. Type "iexpress" (without quotes) into the run window
3. Complete the wizard for creating the installation program.
4. Distribute the completed EXE.

Let's say you have a tar file and you want to uncompress it after placing it in your container, remove it, you can use the COPY command to do this. Butt he various commands would be 1) Copy the tar file to the destination, 2). Uncompress it, 3) Remove the tar file. If you did this in 3 steps then there will be a new image created after each step. You can do this in one step using & but it becomes a hassle.

But you used ADD, then Docker will take care of everything for you and only one intermediate image will be created.

>>> s = "foobar"
>>> list(s)
['f', 'o', 'o', 'b', 'a', 'r']

You need list

This way we can check for an existing file in a particular folder:

 string curFile = @"c:\temp\test.txt";  //Your path
 Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");

For parseInt to work, your string should have only numerical data. Something like this:

 str1 = "123.00";
 str2 = "50.00";
 total = parseInt(str1)+parseInt(str2);
 alert(total);

Can you split the string before you start processing them for a total?

The garbage collector will come around and clean up anything that no longer has references to it. Unless you have unmanaged resources inside Foo, calling Dispose or using a using statement on it won't really help you much.

I'm fairly sure this applies, since it was still in C#. But, I took a game design course using XNA and we spent some time talking about the garbage collector for C#. Garbage collecting is expensive, since you have to check if you have any references to the object you want to collect. So, the GC tries to put this off as long as possible. So, as long as you weren't running out of physical memory when your program went to 700MB, it might just be the GC being lazy and not worrying about it yet.

But, if you just use Foo o outside the loop and create a o = new Foo() each time around, it should all work out fine.

The documentation is here: http://docs.jquery.com/Ajax/jQuery.ajax

But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.

You would call it like this:

$.ajax({
  url: 'mypage.html',
  success: function(){
    alert('success');
  },
  error: function(){
    alert('failure');
  }
});

I have shown the success and error function taking no arguments, but they can receive arguments.

The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.

The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.

For me I had issues with history and location... As the accepted answer using window before history and location (i.e) window.history and window.location solved mine

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

The abort function does this. For example:

Note: the abort message will be written to STDERR as opposed to puts which will write to STDOUT.

Tip: You can also use this method to track certificates that are due to expire soon. This can save your bacon if you discover a cert that is about to expire and can get it fixed in time. Good also for third party companies - for us this is DHL / FedEx. DHL just let a cert expire which is screwing us up 3 days before Thanksgiving. Fortunately I'm around to fix it ... this time!

    private static DateTime? _nextCertWarning;
    private static bool ValidateRemoteCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors error)
    {
        if (error == SslPolicyErrors.None)
        {
            var cert2 = cert as X509Certificate2;
            if (cert2 != null)
            { 
                // If cert expires within 2 days send an alert every 2 hours
                if (cert2.NotAfter.AddDays(-2) < DateTime.Now)
                {
                    if (_nextCertWarning == null || _nextCertWarning < DateTime.Now)
                    {
                        _nextCertWarning = DateTime.Now.AddHours(2);

                        ProwlUtil.StepReached("CERT EXPIRING WITHIN 2 DAYS " + cert, cert.GetCertHashString());   // this is my own function
                    }
                }
            }

I was searching for something similar and came accross something called the Singleton Pattern.

Reference: Singleton Pattern

I am working on a BulkLoader class to load different types of files and wanted to use the Singleton pattern for it. This way I can load files from my main application class and retrieve the loaded files easily from other classes.

Below is a simple example how you can make a score manager for a game with TypeScript and the Singleton pattern.

class SingletonClass {

private static _instance:SingletonClass = new SingletonClass();

private _score:number = 0;

constructor() {
    if(SingletonClass._instance){
        throw new Error("Error: Instantiation failed: Use SingletonDemo.getInstance() instead of new.");
    }
    SingletonClass._instance = this;
}

public static getInstance():SingletonClass
{
    return SingletonClass._instance;
}

public setScore(value:number):void
{
    this._score = value;
}

public getScore():number
{
    return this._score;
}

public addPoints(value:number):void
{
    this._score += value;
}

public removePoints(value:number):void
{
    this._score -= value;
}   }

Then anywhere in your other classes you would get access to the Singleton by:

var scoreManager = SingletonClass.getInstance();
scoreManager.setScore(10); scoreManager.addPoints(1);
scoreManager.removePoints(2); console.log( scoreManager.getScore() );

Please be VERY careful with using the registry key approach. These are machine-wide keys and forcibily migrate ALL applications to .NET 4.0.

Many products do not work if forcibily migrated and this is a testing aid and not a production quality mechanism. Visual Studio 2008 and 2010, MSBuild, turbotax, and a host of websites, SharePoint and so on should not be automigrated.

If you need to use PowerShell with 4.0, this should be done on a per-application basis with a configuration file, you should check with the PowerShell team on the precise recommendation. This is likely to break some existing PowerShell commands.

If you don't want to depend on @@DATEFIRST or use DATEPART(weekday, DateColumn), just calculate the day of the week yourself.

For Monday based weeks (Europe) simplest is:

SELECT DATEDIFF(day, '17530101', DateColumn) % 7 + 1 AS MondayBasedDay

For Sunday based weeks (America) use:

SELECT DATEDIFF(day, '17530107', DateColumn) % 7 + 1 AS SundayBasedDay

This return the weekday number (1 to 7) ever since January 1st respectively 7th, 1753.

Try this function

getQuantileGroupNum <- function(vec, group_num, decreasing=FALSE) {
  if(decreasing) {
    abs(cut(vec, quantile(vec, probs=seq(0, 1, 1 / group_num), type=8, na.rm=TRUE), labels=FALSE, include.lowest=T) - group_num - 1)
  } else {
    cut(vec, quantile(vec, probs=seq(0, 1, 1 / group_num), type=8, na.rm=TRUE), labels=FALSE, include.lowest=T)
  }
}

> t1 <- runif(7)
> t1
[1] 0.4336094 0.2842928 0.5578876 0.2678694 0.6495285 0.3706474 0.5976223
> getQuantileGroupNum(t1, 4)
[1] 2 1 3 1 4 2 4
> getQuantileGroupNum(t1, 4, decreasing=T)
[1] 3 4 2 4 1 3 1

Just change the DropDownStyle to DropDownList. Or if you want it completely read only you can set Enabled = false, or if you don't like the look of that I sometimes have two controls, one readonly textbox and one combobox and then hide the combo and show the textbox if it should be completely readonly and vice versa.

This example based on this trick: https://css-tricks.com/the-checkbox-hack/

I tested it on: chrome, firefox, safari

Option 1: Insert -> Update

If you like to avoid both changes()=0 and INSERT OR IGNORE even if you cannot afford deleting the row - You can use this logic;

First, insert (if not exists) and then update by filtering with the unique key.

Example

-- Table structure
CREATE TABLE players (
    id        INTEGER       PRIMARY KEY AUTOINCREMENT,
    user_name VARCHAR (255) NOT NULL
                            UNIQUE,
    age       INTEGER       NOT NULL
);

-- Insert if NOT exists
INSERT INTO players (user_name, age)
SELECT 'johnny', 20
WHERE NOT EXISTS (SELECT 1 FROM players WHERE user_name='johnny' AND age=20);

-- Update (will affect row, only if found)
-- no point to update user_name to 'johnny' since it's unique, and we filter by it as well
UPDATE players 
SET age=20 
WHERE user_name='johnny';

Regarding Triggers

Notice: I haven't tested it to see the which triggers are being called, but I assume the following:

if row does not exists

• BEFORE INSERT
• INSERT using INSTEAD OF
• AFTER INSERT
• BEFORE UPDATE
• UPDATE using INSTEAD OF
• AFTER UPDATE

if row does exists

• BEFORE UPDATE
• UPDATE using INSTEAD OF
• AFTER UPDATE

Option 2: Insert or replace - keep your own ID

in this way you can have a single SQL command

-- Table structure
CREATE TABLE players (
    id        INTEGER       PRIMARY KEY AUTOINCREMENT,
    user_name VARCHAR (255) NOT NULL
                            UNIQUE,
    age       INTEGER       NOT NULL
);

-- Single command to insert or update
INSERT OR REPLACE INTO players 
(id, user_name, age) 
VALUES ((SELECT id from players WHERE user_name='johnny' AND age=20),
        'johnny',
        20);

Edit: added option 2.

Change this:

EditText editText = (EditText) findViewById(R.id.label_field);

to this:

EditText editText = (EditText)  v.findViewById(R.id.label_field);

This is a way to do it with a while loop:

def reverse(s):
    t = -1
    s2 = ''
    while abs(t) < len(s) + 1: 
        s2 = s2 + s[t]
        t  = t - 1
    return s2

Not for blanks in the middle of a range, but this works for a complex chart from a start date until infinity (ie no need to adjust the chart's data source each time informatiom is added), without showing any lines for dates that have not yet been entered. As you add dates and data to the spreadsheet, the chart expands. Without it, the chart has a brain hemorrhage.

So, to count a complex range of conditions over an extended period of time but only if the date of the events is not blank :

=IF($B6<>"",(COUNTIF($O6:$O6,Q$5)),"") returns “#N/A” if there is no date in column B.

In other words, "count apples or oranges or whatever in column O (as determined by what is in Q5) but only if column B (the dates) is not blank". By returning “#N/A”, the chart will skip the "blank" rows (blank as in a zero value or rather "#N/A").

From that table of returned values you can make a chart from a date in the past to infinity

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

Addition

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/


DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823); 
SET @y2 = @y2 + @y2;
SELECT LEN(@y2), DATALENGTH(@y2)  /*2147483646, 4294967292*/


DECLARE @y3 NVARCHAR(MAX) = @y2 + @y1
SELECT LEN(@y3), DATALENGTH(@y3)   /*6442450940, 12884901880*/

/*This attempt fails*/
SELECT @y1 y1, @y2 y2, @y3 y3

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

The Unsupported major.minor version 51.0 error could mean:

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

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

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

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

for the latest version of the JRE and JDK respectively.

EDIT:

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

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

In the beaten-up MVC pattern, the Servlet is "C" - controller.

Its main job is to do initial request evaluation and then dispatch the processing based on the initial evaluation to the specific worker. One of the worker's responsibilities may be to setup some presentation layer beans and forward the request to the JSP page to render HTML. So, for this reason alone, you need to pass the request object to the service layer.

I would not, though, start writing raw Servlet classes. The work they do is very predictable and boilerplate, something that framework does very well. Fortunately, there are many available, time-tested candidates ( in the alphabetical order ): Apache Wicket, Java Server Faces, Spring to name a few.

It also adds routing using controllers and views with KVO. You'll be able to develop "AJAXy" applications with it.

See it as a lightweight Sproutcore or Cappuccino framework.

To prevent the extra float decimal (i.e. 50.85 - 50 give 0.850000000852), in my case I just need 2 decimals for money cents.

$n = 50.85;
$whole = intval($n);
$fraction = $n * 100 % 100;

Replace:

System.out.println("Enter EmployeeName:");
                 ename=(scanner.next());

with:

System.out.println("Enter EmployeeName:");
                 ename=(scanner.nextLine());

This is because next() grabs only the next token, and the space acts as a delimiter between the tokens. By this, I mean that the scanner reads the input: "firstname lastname" as two separate tokens. So in your example, ename would be set to firstname and the scanner is attempting to set the supervisorId to lastname

I´ve used this:

String currentLanguage = Locale.getDefault().getDisplayLanguage();
if (currentLanguage.toLowerCase().contains("en")) {
   //do something
}

The other answers all use Arrays.asList(), which returns an unmodifiable list (an UnsupportedOperationException is thrown if you try to add or remove an element). To get a mutable list you can wrap the returned list in a new ArrayList as a couple of answers point out, but a cleaner solution is to use Guava's Lists.newArrayList() (available since at least Guava 10, released in 2011).

For example:

Lists.newArrayList("Blargle!");

You can use InitialCatalog Property or builder["Database"] works as well. I tested it with different case and it still works.

1. Migrate your DB "simply make sure the tables and columns exist".
2. Recommended to delete all your data (this freezes MySQL Workbench on my MAC everytime due to "software out of memory..")

1. Open MySQL Workbench
2. click + to make MySQL connection
3. enter credentials and connect
4. go to database tab
5. click reverse engineer
6. follow the wizard Next > Next ….
7. DONE :)
8. now you can click the arrange tab then choose auto-layout (keep clicking it until you are satisfied with the result)

Every Time this has happened, it's been a full disk in my experience.

EDIT

It is also worth noting that this can be caused by a full ramdisk when doing things like altering a large table if you have a ramdisk configured. You can temporarily comment out the ramdisk line to allow such operations if you can't increase the size of it.

You almost have it! The way to do nested list comprehensions is to put the for statements in the same order as they would go in regular nested for statements.

Thus, this

for inner_list in outer_list:
    for item in inner_list:
        ...

corresponds to

[... for inner_list in outer_list for item in inner_list]

So you want

[image for menuitem in list_of_menuitems for image in menuitem]

JAVA_OPTS is not restricted to Tomcat’s Java process, but passed to all JVM processes running on the same machine.

Use CATALINA_OPTS if you specifically want to pass JVM arguments to Tomcat's servlet engine.

It generally occurs when your default port for localhost is being used by another application (like apache tomcat). Easy fix is to stop the application and simply go to localhost/phpmyadmin.

In my case it worked after stopping apache tomcat.

I came to this post looking for a way to have a background color of my ListView Item, yet keep the ripple.

I simply added my color as a background and the selectableItemBackground as a foreground:

<style name="my_list_item">
    <item name="android:background">@color/white</item>
    <item name="android:foreground">?attr/selectableItemBackground</item>
    <item name="android:layout_height">@dimen/my_list_item_height</item>
</style>

and it works like a charm. I guess the same technique could be used for buttons as well. Good luck :)

try this:

function showDiv(divId, element)_x000D_
{_x000D_
    document.getElementById(divId).style.display = element.value == 1 ? 'block' : 'none';_x000D_
}

#hidden_div {_x000D_
    display: none;_x000D_
}

<select id="test" name="form_select" onchange="showDiv('hidden_div', this)">_x000D_
   <option value="0">No</option>_x000D_
   <option value="1">Yes</option>_x000D_
</select>_x000D_
<div id="hidden_div">This is a hidden div</div>

If you want your dependency files to be in some specific folder you can simply use a copy task for it. For Eg.

task copyDepJars(type: Copy) {
  from configurations.compile
  into 'C:\\Users\\athakur\\Desktop\\lib'
}

... or you can wrap you menu div in another:

    <div id="wrapper">
       <div id="menu">
       </div>
    </div>


#wrapper{
         width:800px;
         background: rgba(255, 255, 255, 0.8);
         margin:30px auto;
         border:1px solid red;
    }

    #menu{
        position:fixed;
        border:1px solid green;
        width:300px;
        height:30px;
    }

The NUMBER ONE error is having ANYTHING with the reserved word submit as ID or NAME in your form.

If you plan to call .submit() on the form AND the form has submit as id or name on any form element, then you need to rename that form element, since the form’s submit method/handler is shadowed by the name/id attribute.

Several other things:

As mentioned, you need to submit the form using a simpler event than the jQuery one

BUT you also need to cancel the clicks on the links

Why, by the way, do you have two buttons? Since you use jQuery to submit the form, you will never know which of the two buttons were clicked unless you set a hidden field on click.

<form action="deletprofil.php" id="form_id" method="post">
  <div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
  <button type="submit" value="1" class="ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Anlegen</button>
  <button type="submit" value="2" class="ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Bnlegen</button>
  </div>
</form> 

 $(function(){
    $("#NOlink, #OKlink").on("click", function(e) {
        e.preventDefault(); // cancel default action
        $("#popupDialog").popup('close');
        if (this.id=="OKlink") { 
          document.getElementById("form_id").submit(); // or $("#form_id")[0].submit();
        }
    });

    $('#form_id').on('submit', function(e){
      e.preventDefault();
      $("#popupDialog").popup('open');
    });
});    

Judging from your comments, I think you really want to do this:

<form action="deletprofil.php" id="form_id" method="post">
  <input type="hidden" id="whichdelete" name="whichdelete" value="" />
  <div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
  <button type="button" value="1" class="delete ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Anlegen</button>
  <button type="button" value="2" class="delete ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Bnlegen</button>
  </div>
</form> 

 $(function(){
    $("#NOlink, #OKlink").on("click", function(e) {
        e.preventDefault(); // cancel default action
        $("#popupDialog").popup('close');
        if (this.id=="OKlink") { 
          // trigger the submit event, not the event handler
          document.getElementById("form_id").submit(); // or $("#form_id")[0].submit();
        }
    });
    $(".delete").on("click", function(e) {
        $("#whichdelete").val(this.value);
    });
    $('#form_id').on('submit', function(e){
      e.preventDefault();
      $("#popupDialog").popup('open');
    });
});
