As said Will Wagner, in old version of jsp you should always use c:out to output dynamic text.

Moreover, using this syntax:

<c:out value="${person.name}">No name</c:out>

you can display the text "No name" when name is null.

Do you have control over running the transformation? If so, you could pass in the current date to the XSL and use $current-date from inside your XSL. Below is how you declare the incoming parameter, but with knowing how you are running the transformation, I can't tell you how to pass in the value.

<xsl:param name="current-date" />

For example, from the bash script, use:

xsltproc --stringparam current-date `date +%Y-%m-%d` -o output.html path-to.xsl path-to.xml

Then, in the xsl you can use:

<xsl:value-of select="$current-date"/>

Check if it's visible.

$("#singlechatpanel-1").is(':visible');

Check if it's hidden.

$("#singlechatpanel-1").is(':hidden');

SELECT CONVERT(uniqueidentifier,STUFF(STUFF(STUFF(STUFF('B33D42A3AC5A4D4C81DD72F3D5C49025',9,0,'-'),14,0,'-'),19,0,'-'),24,0,'-'))

I would use something like x.substring(0, x.lastIndexOf('.')). If you're going for performance, don't go for javascript at all :-p No, one more statement really doesn't matter for 99.99999% of all purposes.

MFMailComposeViewController is the way to go after the release of iPhone OS 3.0 software. You can look at the sample code or the tutorial I wrote.

I had to investigate an endless recursion in smartgwt with IE11, so in order to investigate deeper, I needed a stack trace. The problem was, that I was unable to use the dev console, because the reproduction was more difficult that way.
Use the following in a javascript method:

try{ null.toString(); } catch(e) { alert(e.stack); }

By the time the image is loaded, the renderer has already drawn the scene, hence it is too late. The solution is to change

texture = THREE.ImageUtils.loadTexture('crate.gif'),

into

texture = THREE.ImageUtils.loadTexture('crate.gif', {}, function() {
    renderer.render(scene);
}),

you could search with aptitude search intl after you can choose the right one, for example sudo aptitude install php-intl and finally sudo service apache2 restart

good Luck!

I suggest creating an additional connection for the second command, would solve it. Try to combine both queries in one query. Create a subquery for the count.

while (dr3.Read())
{
    dados_historico[4] = dr3["QT"].ToString(); //quantidade de emails lidos naquela verificação
}

Why override the same value again and again?

if (dr3.Read())
{
    dados_historico[4] = dr3["QT"].ToString(); //quantidade de emails lidos naquela verificação
}

Would be enough.

Just Create a directive and add below hostlistener:

@HostListener('input', ['$event'])
    onInput(event: Event) {
        this.elementRef.nativeElement.value = (<HTMLInputElement>event.currentTarget).value.replace(/[^0-9]/g, '');
    }

Replace invalid text with empty. All keys and key combinations will now work across all browsers till IE9.

Its as simple as if([myString isEqual:@""]) or if([myString isEqualToString:@""])

change Date to Object which is between parenthesis

I know this question is already been answered but for new comers those two solutions may help:

1. Make sure your gmail is allowing low secure apps to sign in, you can turn it on here: https://www.google.com/settings/security/lesssecureapps.
2. Change your password.

Your implementation must like:

public boolean equals2(Object object2) {
    if(a.equals(object2.a)) {
        return true;
    }
    else return false;
}

With this implementation your both methods would work.

Your selector is retrieving the text box's surrounding <div class='textBoxEmployeeNumber'> instead of the input inside it.

// Access the input inside the div with this selector:
$(function () {
  $('.textBoxEmployeeNumber input').val("fgg");
});

Update after seeing output HTML

If the ASP.NET code reliably outputs the HTML <input> with an id attribute id='EmployeeId', you can more simply just use:

$(function () {
  $('#EmployeeId').val("fgg");
});

Failing this, you will need to verify in your browser's error console that you don't have other script errors causing this to fail. The first example above works correctly in this demonstration.

There's a technique called Immersive Full-Screen Mode available in KitKat.

Example

I was having the same problem with the fetch command. A quick look at the docs from here tells us this:

If the server you are requesting from doesn't support CORS, you should get an error in the console indicating that the cross-origin request is blocked due to the CORS Access-Control-Allow-Origin header being missing.

You can use no-cors mode to request opaque resources.

fetch('https://bar.com/data.json', {
  mode: 'no-cors' // 'cors' by default
})
.then(function(response) {
  // Do something with response
});

You can get every file, then filter the array:

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dirInfo, params string[] extensions)
{
    var allowedExtensions = new HashSet<string>(extensions, StringComparer.OrdinalIgnoreCase);

    return dirInfo.EnumerateFiles()
                  .Where(f => allowedExtensions.Contains(f.Extension));
}

This will be (marginally) faster than every other answer here.
In .Net 3.5, replace EnumerateFiles with GetFiles (which is slower).

And use it like this:

var files = new DirectoryInfo(...).GetFilesByExtensions(".jpg", ".mov", ".gif", ".mp4");

For AWS users.

I had to use the following steps to get there.

1) Ensure that pip and django are installed at the sudo level

• sudo apt-get install python-pip
• sudo pip install django

2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0

• configured through AWS console

3) Add Public IP and DNS to ALLOWED_HOSTS

• ALLOWED_HOSTS is a list object that you can find in settings.py
• ALLOWED_HOSTS = ["75.254.65.19","ec2-54-528-27-21.compute-1.amazonaws.com"]

4) Launch development server with sudo on port 80

• sudo python manage.py runserver 0:80

Site now available at either of the following (no need for :80 as that is default for http):

• [Public DNS] i.e. ec2-54-528-27-21.compute-1.amazonaws.com
• [Public IP] i.e 75.254.65.19

[v[0] for v in sorted(foo.items(), key=lambda(k,v): (v,k))]

you can use native javascript like this

<script>_x000D_
function myFunction() {_x000D_
  var input, filter, table, tr, td, i;_x000D_
  input = document.getElementById("myInput");_x000D_
  filter = input.value.toUpperCase();_x000D_
  table = document.getElementById("myTable");_x000D_
  tr = table.getElementsByTagName("tr");_x000D_
  for (i = 0; i < tr.length; i++) {_x000D_
    td = tr[i].getElementsByTagName("td")[0];_x000D_
    if (td) {_x000D_
      if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {_x000D_
        tr[i].style.display = "";_x000D_
      } else {_x000D_
        tr[i].style.display = "none";_x000D_
      }_x000D_
    }       _x000D_
  }_x000D_
}_x000D_
</script>

You can also use PDCurses library. (http://pdcurses.sourceforge.net/)

you can try implementing this ForkJoinWorkerThreadFactory and inject it to Fork-Join class.

public ForkJoinPool(int parallelism,
                        ForkJoinWorkerThreadFactory factory,
                        UncaughtExceptionHandler handler,
                        boolean asyncMode) {
        this(checkParallelism(parallelism),
             checkFactory(factory),
             handler,
             asyncMode ? FIFO_QUEUE : LIFO_QUEUE,
             "ForkJoinPool-" + nextPoolId() + "-worker-");
        checkPermission();
    }

you can use this constructor of Fork-Join pool to do this.

notes:-- 1. if you use this, take into consideration that based on your implementation of new threads, scheduling from JVM will be affected, which generally schedules fork-join threads to different cores(treated as a computational thread). 2. task scheduling by fork-join to threads won't get affected. 3. Haven't really figured out how parallel stream is picking threads from fork-join(couldn't find proper documentation on it), so try using a different threadNaming factory so as to make sure, if threads in parallel stream are being picked from customThreadFactory that you provide. 4. commonThreadPool won't use this customThreadFactory.

I'm usually using

var dictionary:[String:String] = [:]
dictionary.removeAll()

Minor changes required for Kafka 0.10 and the new consumer compared to laughing_man's answer:

• Broker: No changes, you still need to increase properties message.max.bytes and replica.fetch.max.bytes. message.max.bytes has to be equal or smaller(*) than replica.fetch.max.bytes.
• Producer: Increase max.request.size to send the larger message.
• Consumer: Increase max.partition.fetch.bytes to receive larger messages.

(*) Read the comments to learn more about message.max.bytes<=replica.fetch.max.bytes

In Android Studio 3.1.2 I have faced the same issue. I resolved this issue by click on "File->Sync Project with Gradle Files".This works for me. :)

Any data type which is lower than "int" (except Boolean) is implicitly converts to "int".

In your case:

short a = 2;
short b = 3;
short c = a + b;

The result of (a+b) is implicitly converted to an int. And now you are assigning it to "short".So that you are getting the error.

short,byte,char --for all these we will get same error.

As doc says also keep in mind the correct value combination:

The setting must be one of the values listed in the following table, or a combination of one "state..." value plus one "adjust..." value. Setting multiple values in either group — multiple "state..." values, for example — has undefined results. Individual values are separated by a vertical bar (|). For example:

<activity android:windowSoftInputMode="stateVisible|adjustResize" . . . >

Sometime missing "jasmine" from tsconfig.json may cause this error. (TypeScript 2.X)

So add

"types": [
  "node",
  "jasmine"
]

to your tsconfig.json file.

Use Assembly.GetTypes. For example:

Assembly mscorlib = typeof(string).Assembly;
foreach (Type type in mscorlib.GetTypes())
{
    Console.WriteLine(type.FullName);
}

If you don't mind importing the sklearn library, I would recommend the method talked on this blog.

import pandas as pd
from sklearn import preprocessing

data = {'score': [234,24,14,27,-74,46,73,-18,59,160]}
cols = data.columns
df = pd.DataFrame(data)
df

min_max_scaler = preprocessing.MinMaxScaler()
np_scaled = min_max_scaler.fit_transform(df)
df_normalized = pd.DataFrame(np_scaled, columns = cols)
df_normalized

f = open('hi.txt', 'w')
f.write('0123456789abcdef')
f.close()
f = open('hej.txt', 'r')
f.seek(12)
print f.read(1) # This will read just "c"

You could also use

$(this).find('img');

which would return all imgs that are descendants of the div

[^\s-]

should work and so will

[^-\s]

• [] : The char class
• ^ : Inside the char class ^ is the negator when it appears in the beginning.
• \s : short for a white space
• - : a literal hyphen. A hyphen is a meta char inside a char class but not when it appears in the beginning or at the end.

Well, if you know where your user lives in the AD hierarchy (e.g. quite possibly in the "Users" container, if it's a small network), you could also bind to the user account directly, instead of searching for it.

DirectoryEntry deUser = new DirectoryEntry("LDAP://cn=John Doe,cn=Users,dc=yourdomain,dc=com");

if (deUser != null)
{
  ... do something with your user
}

And if you're on .NET 3.5 already, you could even use the vastly expanded System.DirectorySrevices.AccountManagement namespace with strongly typed classes for each of the most common AD objects:

// bind to your domain
PrincipalContext pc = new PrincipalContext(ContextType.Domain, "LDAP://dc=yourdomain,dc=com");

// find the user by identity (or many other ways)
UserPrincipal user = UserPrincipal.FindByIdentity(pc, "cn=John Doe");

There's loads of information out there on System.DirectoryServices.AccountManagement - check out this excellent article on MSDN by Joe Kaplan and Ethan Wilansky on the topic.

In Quora, somebody says:

First of all, it is totally possible to write apps with React without Flux.

Also this visual diagram which I've created to show a quick view of both, probably a quick answer for the people who don't want to read the whole explanation:

But if you still interested knowing more, read on.

I believe you should start with pure React, then learn Redux and Flux. After you will have some REAL experience with React, you will see whether Redux is helpful for you or not.

Maybe you will feel that Redux is exactly for your app and maybe you will find out, that Redux is trying to solve a problem you are not really experiencing.

If you start directly with Redux, you may end up with over-engineered code, code harder to maintain and with even more bugs and than without Redux.

From Redux docs:

Motivation
As the requirements for JavaScript single-page applications have become increasingly complicated, our code must manage more state than ever before. This state can include server responses and cached data, as well as locally created data that has not yet been persisted to the server. UI state is also increasing in complexity, as we need to manage active routes, selected tabs, spinners, pagination controls, and so on.

Managing this ever-changing state is hard. If a model can update another model, then a view can update a model, which updates another model, and this, in turn, might cause another view to update. At some point, you no longer understand what happens in your app as you have lost control over the when, why, and how of its state. When a system is opaque and non-deterministic, it's hard to reproduce bugs or add new features.

As if this wasn't bad enough, consider the new requirements becoming common in front-end product development. As developers, we are expected to handle optimistic updates, server-side rendering, fetching data before performing route transitions, and so on. We find ourselves trying to manage a complexity that we have never had to deal with before, and we inevitably ask the question: Is it time to give up? The answer is No.

This complexity is difficult to handle as we're mixing two concepts that are very hard for the human mind to reason about: mutation and asynchronicity. I call them Mentos and Coke. Both can be great when separated, but together they create a mess. Libraries like React attempt to solve this problem in the view layer by removing both asynchrony and direct DOM manipulation. However, managing the state of your data is left up to you. This is where Redux comes in.

Following in the footsteps of Flux, CQRS, and Event Sourcing, Redux attempts to make state mutations predictable by imposing certain restrictions on how and when updates can happen. These restrictions are reflected in the three principles of Redux.

Also from Redux docs:

Core Concepts
Redux itself is very simple.

Imagine your app's state is described as a plain object. For example, the state of a todo app might look like this:

{
  todos: [{
    text: 'Eat food',
    completed: true
  }, {
    text: 'Exercise',
    completed: false
  }],
  visibilityFilter: 'SHOW_COMPLETED'
}

This object is like a "model" except that there are no setters. This is so that different parts of the code can’t change the state arbitrarily, causing hard-to-reproduce bugs.

To change something in the state, you need to dispatch an action. An action is a plain JavaScript object (notice how we don't introduce any magic?) that describes what happened. Here are a few example actions:

{ type: 'ADD_TODO', text: 'Go to swimming pool' }
{ type: 'TOGGLE_TODO', index: 1 }
{ type: 'SET_VISIBILITY_FILTER', filter: 'SHOW_ALL' }

Enforcing that every change is described as an action lets us have a clear understanding of what’s going on in the app. If something changed, we know why it changed. Actions are like breadcrumbs of what has happened. Finally, to tie state and actions together, we write a function called a reducer. Again, nothing magic about it — it's just a function that takes state and action as arguments, and returns the next state of the app. It would be hard to write such a function for a big app, so we write smaller functions managing parts of the state:

function visibilityFilter(state = 'SHOW_ALL', action) {
  if (action.type === 'SET_VISIBILITY_FILTER') {
    return action.filter;
  } else {
    return state;
  }
}

function todos(state = [], action) {
  switch (action.type) {
  case 'ADD_TODO':
    return state.concat([{ text: action.text, completed: false }]);
  case 'TOGGLE_TODO':
    return state.map((todo, index) =>
      action.index === index ?
        { text: todo.text, completed: !todo.completed } :
        todo
   )
  default:
    return state;
  }
}

And we write another reducer that manages the complete state of our app by calling those two reducers for the corresponding state keys:

function todoApp(state = {}, action) {
  return {
    todos: todos(state.todos, action),
    visibilityFilter: visibilityFilter(state.visibilityFilter, action)
  };
}

This is basically the whole idea of Redux. Note that we haven't used any Redux APIs. It comes with a few utilities to facilitate this pattern, but the main idea is that you describe how your state is updated over time in response to action objects, and 90% of the code you write is just plain JavaScript, with no use of Redux itself, its APIs, or any magic.

Just a quick power set refresher !

Power set of a set X, is simply the set of all subsets of X including the empty set

Example set X = (a,b,c)

Power Set = { { a , b , c } , { a , b } , { a , c } , { b , c } , { a } , { b } , { c } , { } }

Here is another way of finding power set:

def power_set(input):
    # returns a list of all subsets of the list a
    if (len(input) == 0):
        return [[]]
    else:
        main_subset = [ ]
        for small_subset in power_set(input[1:]):
            main_subset += [small_subset]
            main_subset += [[input[0]] + small_subset]
        return main_subset

print(power_set([0,1,2,3]))

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

 var span = TimeSpan.FromMinutes(2);
 var t = Task.Factory.StartNew(async delegate / () =>
   {
        this.SomeAsync();
        await Task.Delay(span, source.Token);
  }, source.Token, TaskCreationOptions.LongRunning, TaskScheduler.Default);

source.Cancel(true/or not);

// or use ThreadPool(whit defaul options thread) like this
Task.Start(()=>{...}), source.Token)

if u like use some loop thread inside ...

public async void RunForestRun(CancellationToken token)
{
  var t = await Task.Factory.StartNew(async delegate
   {
       while (true)
       {
           await Task.Delay(TimeSpan.FromSeconds(1), token)
                 .ContinueWith(task => { Console.WriteLine("End delay"); });
           this.PrintConsole(1);
        }
    }, token) // drop thread options to default values;
}

// And somewhere there
source.Cancel();
//or
token.ThrowIfCancellationRequested(); // try/ catch block requred.

This will let Git authenticate on HTTPS using .netrc:

• The file should be named _netrc and located in c:\Users\<username>.
• You will need to set an environment variable called HOME=%USERPROFILE% (set system-wide environment variables using the System option in the control panel. Depending on the version of Windows, you may need to select "Advanced Options".).
• The password stored in the _netrc file cannot contain spaces (quoting the password will not work).

It also happens if you're trying to access an instance when you have a pointer, and vice versa:

struct foo
{
  int x, y, z;
};

struct foo a, *b = &a;

b.x = 12;  /* This will generate the error, should be b->x or (*b).x */

As pointed out in a comment, this can be made excruciating if someone goes and typedefs a pointer, i.e. includes the * in a typedef, like so:

typedef struct foo* Foo;

Because then you get code that looks like it's dealing with instances, when in fact it's dealing with pointers:

Foo a_foo = get_a_brand_new_foo();
a_foo->field = FANTASTIC_VALUE;

Note how the above looks as if it should be written a_foo.field, but that would fail since Foo is a pointer to struct. I strongly recommend against typedef:ed pointers in C. Pointers are important, don't hide your asterisks. Let them shine.

You may like to first create a dialogue by right clicking the project in solution explorer and in the code file type

dialogue1.show()

that's all !!!

>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> [x for x in L if x is not None]
[0, 23, 234, 89, 0, 35, 9]

Just for fun, here's how you can adapt filter to do this without using a lambda, (I wouldn't recommend this code - it's just for scientific purposes)

>>> from operator import is_not
>>> from functools import partial
>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> filter(partial(is_not, None), L)
[0, 23, 234, 89, 0, 35, 9]

I have not found suitable answer, so here goes my take, which builds upon @toszter answer, but does not use system Python (and you may know, it is not always good idea to install setuptools and virtualenv at system level when dealing with many Python configurations):

#!/bin/sh

mkdir python_ve
cd python_ve

MYROOT=`pwd`
mkdir env pyenv dep

cd ${MYROOT}/dep
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-15.2.tar.gz#md5=a9028a9794fc7ae02320d32e2d7e12ee
wget https://raw.github.com/pypa/virtualenv/master/virtualenv.py
wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
xz -d Python-2.7.9.tar.xz

cd ${MYROOT}/pyenv
tar xf ../dep/Python-2.7.9.tar
cd Python-2.7.9
./configure --prefix=${MYROOT}/pyenv && make -j 4 && make install

cd ${MYROOT}/pyenv

tar xzf ../dep/setuptools-15.2.tar.gz

cd ${MYROOT}

pyenv/bin/python dep/virtualenv.py --no-setuptools --python=${MYROOT}/pyenv/bin/python --verbose env
env/bin/python pyenv/setuptools-15.2/setup.py install
env/bin/easy_install pip

echo "virtualenv in ${MYROOT}/env"

The trick of breaking chicken-egg problem here is to make virtualenv without setuptools first, because it otherwise fails (pip can not be found). It may be possible to install pip / wheel directly, but somehow easy_install was the first thing which came to my mind. Also, the script can be improved by factoring out concrete versions.

NB. Using xz in the script.

We do all our enums like this when it comes to Rest/Json etc. It has the advantage that the error is human readable and also gives you the accepted value list. We are using a custom method MyEnum.fromString instead of MyEnum.valueOf, hope it helps.

public enum MyEnum {

    A, B, C, D;

    private static final Map<String, MyEnum> NAME_MAP = Stream.of(values())
            .collect(Collectors.toMap(MyEnum::toString, Function.identity()));

    public static MyEnum fromString(final String name) {
        MyEnum myEnum = NAME_MAP.get(name);
        if (null == myEnum) {
            throw new IllegalArgumentException(String.format("'%s' has no corresponding value. Accepted values: %s", name, Arrays.asList(values())));
        }
        return myEnum;
    }
}

so for example if you call

MyEnum value = MyEnum.fromString("X");

you'll get an IllegalArgumentException with the following message:

'X' has no corresponding value. Accepted values: [A, B, C, D]

you can change the IllegalArgumentException to a custom one.

Without the main sentinel, the code would be executed even if the script were imported as a module.

You have to execute request in background. A simple way could be using an Executors :

Executors.newSingleThreadExecutor().execute { 
   yourDb.yourDao.yourRequest() //Replace this by your request
}

Some good answers here. Especially the one by @torek. I thought I'd add this work-around with a little explanation for those in a rush.

To summarize, what happens is that when you move a tag locally, it changes the tag from a non-Null commit value to a different value. However, because git (as a default behavior) doesn't allow changing non-Null remote tags, you can't push the change.

The work-around is to delete the tag (and tick remove all remotes). Then create the same tag and push.

I know it's "a bit late" but just in case if anybody needs to do this in LINQ Method syntax (which is why I found this post initially), this would be how to do that:

var results = context.Periods
    .GroupJoin(
        context.Facts,
        period => period.id,
        fk => fk.periodid,
        (period, fact) => fact.Where(f => f.otherid == 17)
                              .Select(fact.Value)
                              .DefaultIfEmpty()
    )
    .Where(period.companyid==100)
    .SelectMany(fact=>fact).ToList();

Python opens files almost in the same way as in C:

• r+ Open for reading and writing. The stream is positioned at the beginning of the file.

• a+ Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file, but output is appended to the end of the file (but in some Unix systems regardless of the current seek position).

This answer seems quite outdated and not adapt for nowadays single page applications. In my case I found the solution thank to this aricle where a simple but effective solution is proposed:

html,
body {
  position: fixed;
  overflow: hidden;
}

This solution it's not applicable if your body is your scroll container.

Using javascript function it is easier to get all the attributes of an element in NamedArrayFormat.

$("#myTestDiv").click(function(){_x000D_
  var attrs = document.getElementById("myTestDiv").attributes;_x000D_
  $.each(attrs,function(i,elem){_x000D_
    $("#attrs").html(    $("#attrs").html()+"<br><b>"+elem.name+"</b>:<i>"+elem.value+"</i>");_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>_x000D_
<div id="myTestDiv" ekind="div" etype="text" name="stack">_x000D_
click This_x000D_
</div>_x000D_
<div id="attrs">Attributes are <div>

Do the following :

"CREATE APPLICATION" having the same name which you want to upload before.

Considering React Function Components and using Hooks are getting more popular these days , I will give a simple example of how to Passing data from child to parent component

in Parent Function Component we will have :

import React, { useState, useEffect } from "react";

then

const [childData, setChildData] = useState("");

and passing setChildData (which do a job similar to this.setState in Class Components) to Child

return( <ChildComponent passChildData={setChildData} /> )

in Child Component first we get the receiving props

function ChildComponent(props){ return (...) }

then you can pass data anyhow like using a handler function

const functionHandler = (data) => {

props.passChildData(data);

}

Here is one case that caught me out, using a global as a default value of a parameter.

globVar = None    # initialize value of global variable

def func(param = globVar):   # use globVar as default value for param
    print 'param =', param, 'globVar =', globVar  # display values

def test():
    global globVar
    globVar = 42  # change value of global
    func()

test()
=========
output: param = None, globVar = 42

I had expected param to have a value of 42. Surprise. Python 2.7 evaluated the value of globVar when it first parsed the function func. Changing the value of globVar did not affect the default value assigned to param. Delaying the evaluation, as in the following, worked as I needed it to.

def func(param = eval('globVar')):       # this seems to work
    print 'param =', param, 'globVar =', globVar  # display values

Or, if you want to be safe,

def func(param = None)):
    if param == None:
        param = globVar
    print 'param =', param, 'globVar =', globVar  # display values

Set alignment: Alignment.centerRight in Container:

Container(
    alignment: Alignment.centerRight,
    child:Text(
       "Hello",
    ),
)

Start your script with the following line. The script will first run and then you will get the python command prompt. At this point all variables and functions will be available for interactive use and invocations.

#!/usr/bin/env python -i

Try this, it's working for me.

Sender:

byte[] message = ...
Socket socket = ...
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

dOut.writeInt(message.length); // write length of the message
dOut.write(message);           // write the message

Receiver:

Socket socket = ...
DataInputStream dIn = new DataInputStream(socket.getInputStream());

int length = dIn.readInt();                    // read length of incoming message
if(length>0) {
    byte[] message = new byte[length];
    dIn.readFully(message, 0, message.length); // read the message
}

I've been using the Regex.IsMatch().

First of all you need to add the next statement:

using System.Text.RegularExpressions;

Then the method looks like:

private bool EmailValidation(string pEmail)
{
                 return Regex.IsMatch(pEmail,
                 @"^(?("")("".+?(?<!\\)""@)|(([0-9a-z]((\.(?!\.))|[-!#\$%&'\*\+/=\?\^`\{\}\|~\w])*)(?<=[0-9a-z])@))" +
                 @"(?(\[)(\[(\d{1,3}\.){3}\d{1,3}\])|(([0-9a-z][-\w]*[0-9a-z]*\.)+[a-z0-9][\-a-z0-9]{0,22}[a-z0-9]))$",
                 RegexOptions.IgnoreCase, TimeSpan.FromMilliseconds(250));
}

It's a private method because of my logic but you can put the method as static in another Layer such as "Utilities" and call it from where you need.

Just reimport project. :) I tried cleaning up the cache and refreshing dependencies doesn't work but failed.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

I solved similar problem this way:

@Component
public class DataLoader {

    @Autowired
    private UserRepository userRepository;

    //method invoked during the startup
    @PostConstruct
    public void loadData() {
        userRepository.save(new User("user"));
    }

    //method invoked during the shutdown
    @PreDestroy
    public void removeData() {
        userRepository.deleteAll();
    }
}

A very common issue not described yet that front-end coders often run into is the scope that is visible to an inline event handler in the HTML - for example, with

<button onclick="foo()"></button>

The scope of the variables that an on* attribute can reference must be either:

• global (working inline handlers almost always reference global variables)
• a property of the document (eg, querySelector as a standalone variable will point to document.querySelector; rare)
• a property of the element the handler is attached to (like above; rare)

Otherwise, you'll get a ReferenceError when the handler is invoked. So, for example, if the inline handler references a function which is defined inside window.onload or $(function() {, the reference will fail, because the inline handler may only reference variables in the global scope, and the function is not global:

window.addEventListener('DOMContentLoaded', () => {_x000D_
  function foo() {_x000D_
    console.log('foo running');_x000D_
  }_x000D_
});

<button onclick="foo()">click</button>

Properties of the document and properties of the element the handler is attached to may also be referenced as standalone variables inside inline handlers because inline handlers are invoked inside of two with blocks, one for the document, one for the element. The scope chain of variables inside these handlers is extremely unintuitive, and a working event handler will probably require a function to be global (and unnecessary global pollution should probably be avoided).

Since the scope chain inside inline handlers is so weird, and since inline handlers require global pollution to work, and since inline handlers sometimes require ugly string escaping when passing arguments, it's probably easier to avoid them. Instead, attach event handlers using Javascript (like with addEventListener), rather than with HTML markup.

function foo() {_x000D_
  console.log('foo running');_x000D_
}_x000D_
document.querySelector('.my-button').addEventListener('click', foo);

<button class="my-button">click</button>

On a different note, unlike normal <script> tags, which run on the top level, code inside ES6 modules runs in its own private scope. A variable defined at the top of a normal <script> tag is global, so you can reference it in other <script> tags, like this:

<script>_x000D_
const foo = 'foo';_x000D_
</script>_x000D_
<script>_x000D_
console.log(foo);_x000D_
</script>

But the top level of an ES6 module is not global. A variable declared at the top of an ES6 module will only be visible inside that module, unless the variable is explicitly exported, or unless it's assigned to a property of the global object.

<script type="module">_x000D_
const foo = 'foo';_x000D_
</script>_x000D_
<script>_x000D_
// Can't access foo here, because the other script is a module_x000D_
console.log(typeof foo);_x000D_
</script>

The top level of an ES6 module is similar to that of the inside of an IIFE on the top level in a normal <script>. The module can reference any variables which are global, and nothing can reference anything inside the module unless the module is explicitly designed for it.

You can use

@PostConstruct
public void init() {
   // ...
}

you can use command line query and execute in mssql:

exec xp_cmdshell 'ipconfig'

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

>>> [1]

PowerShell has aliases for several common commands like echo. Type the following in PowerShell:

Get-Alias echo

to get a response:

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           echo -> Write-Output

Even Get-Alias has an alias gal -> Get-Alias. You could write gal echo to get the alias for echo.

gal echo

Other aliases are listed here: https://docs.microsoft.com/en-us/powershell/scripting/learn/using-familiar-command-names?view=powershell-6

cat dir mount rm cd echo move rmdir chdir erase popd sleep clear h ps sort cls history pushd tee copy kill pwd type del lp r write diff ls ren

If you would like to replace white spaces in a particular column value, you can use the following script to do the job for you,

UPDATE TableName TN
   SET TN.Column_Name   = TRIM (TN.Column_Name);

SELECT * FROM employees WHERE name NOT IN (SELECT name FROM eotm_dyn)

OR

SELECT * FROM employees WHERE NOT EXISTS (SELECT * FROM eotm_dyn WHERE eotm_dyn.name = employees.name)

OR

SELECT * FROM employees LEFT OUTER JOIN eotm_dyn ON eotm_dyn.name = employees.name WHERE eotm_dyn IS NULL

My issue started when I tried to change the server from IIS Express to Local IIS (while using LocalDB).

I was using LocalDB (for dev purposes), and when I went to revert from Local IIS to IIS Express, Visual Studio had switched my data source from Data Source=(LocalDb)\MSSQLLocalDB to Data Source=.\SQLEXPRESS

Incorrect connection string

<add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\SurveyTestsDB.mdf;Initial Catalog=SurveyTestsDB;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />

Correct connection string

<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\SurveyTestsDB.mdf;Initial Catalog=SurveyTestsDB;Integrated Security=True" providerName="System.Data.SqlClient" />

Hope this helps someone out there.

Unless you are in a strict console application, I wouldn't use it, because you can't really see it. I would use Trace.WriteLine() for debugging-type information that can be turned on and off in production.

I think it's better to use the chrome toggle device toolbar with the chrome inspector. It provides you a user agent switch along with responsive mode.

If you are using NodeJS, you can use the build-in util function:

import * as util from "util";
util.format('My string: %s', 'foo');

                </div>
            </li>
<script>
$(function(){
$('#thumbnail').on('change', function() {
    var file = $(this).get(0).files;
    var reader = new FileReader();
    reader.readAsDataURL(file[0]);
    reader.addEventListener("load", function(e) {
    var image = e.target.result;
$("#imgthumbnail").attr('src', image);

Building on top of Tomas's answer, this is the best approach of finding the location tap position as an integer I found:

adb shell getevent -l | grep ABS_MT_POSITION --line-buffered | awk '{a = substr($0,54,8); sub(/^0+/, "", a); b = sprintf("0x%s",a); printf("%d\n",strtonum(b))}'

Use adb shell getevent -l to get a list of events, the using grep for ABS_MT_POSITION (gets the line with touch events in hex) and finally use awk to get the relevant hex values, strip them of zeros and convert hex to integer. This continuously prints the x and y coordinates in the terminal only when you press on the device.

You can then use this adb shell command to send the command:

adb shell input tap x y

Maybe something like this?

UPDATE [MyTable]
SET [SomeField] = NULL
WHERE [SomeField] is not NULL
AND LEN(LTRIM(RTRIM([SomeField]))) = 0

You can find out something like this in C#.

This is what I used in JUnit - Selenium

WebDriverWait wait = new WebDriverWait(driver, 100);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("submit")));

Do import related packages.

easy way to do it: To get the actual user count:

$ADInfo = Get-ADGroup -Identity '<groupname>' -Properties Members
$AdInfo.Members.Count

and you get the count easily, it is pretty fast as well for 20k+ users too

An overview of the const and constexpr keywords

In C ++, if a const object is initialized with a constant expression, we can use our const object wherever a constant expression is required.

const int x = 10;
int a[x] = {0};

For example, we can make a case statement in switch.

constexpr can be used with arrays.

constexpr is not a type.

The constexpr keyword can be used in conjunction with the auto keyword.

constexpr auto x = 10;

struct Data {   // We can make a bit field element of struct.   
    int a:x;
 };

If we initialize a const object with a constant expression, the expression generated by that const object is now a constant expression as well.

Constant Expression : An expression whose value can be calculated at compile time.

x*5-4 // This is a constant expression. For the compiler, there is no difference between typing this expression and typing 46 directly.

Initialize is mandatory. It can be used for reading purposes only. It cannot be changed. Up to this point, there is no difference between the "const" and "constexpr" keywords.

NOTE: We can use constexpr and const in the same declaration.

constexpr const int* p;

Constexpr Functions

Normally, the return value of a function is obtained at runtime. But calls to constexpr functions will be obtained as a constant in compile time when certain conditions are met.

NOTE : Arguments sent to the parameter variable of the function in function calls or to all parameter variables if there is more than one parameter, if C.E the return value of the function will be calculated in compile time. !!!

constexpr int square (int a){
return a*a;
}

constexpr int a = 3;
constexpr int b = 5;

int arr[square(a*b+20)] = {0}; //This expression is equal to int arr[35] = {0};

In order for a function to be a constexpr function, the return value type of the function and the type of the function's parameters must be in the type category called "literal type".

The constexpr functions are implicitly inline functions.

An important point :

None of the constexpr functions need to be called with a constant expression.It is not mandatory. If this happens, the computation will not be done at compile time. It will be treated like a normal function call. Therefore, where the constant expression is required, we will no longer be able to use this expression.

The conditions required to be a constexpr function are shown below;

1 ) The types used in the parameters of the function and the type of the return value of the function must be literal type.

2 ) A local variable with static life time should not be used inside the function.

3 ) If the function is legal, when we call this function with a constant expression in compile time, the compiler calculates the return value of the function in compile time.

4 ) The compiler needs to see the code of the function, so constexpr functions will almost always be in the header files.

5 ) In order for the function we created to be a constexpr function, the definition of the function must be in the header file.Thus, whichever source file includes that header file will see the function definition.

Bonus

Normally with Default Member Initialization, static data members with const and integral types can be initialized within the class. However, in order to do this, there must be both "const" and "integral types".

If we use static constexpr then it doesn't have to be an integral type to initialize it inside the class. As long as I initialize it with a constant expression, there is no problem.

class Myclass  {
         const static int sx = 15;         // OK
         constexpr static int sy = 15;     // OK
         const static double sd = 1.5;     // ERROR
         constexpr static double sd = 1.5; // OK
 };

In C language, objects with static storage duration have to be initialized with constant expressions, or with aggregate initializers containing constant expressions.

A "large" object is never a constant expression in C, even if the object is declared as const.

Moreover, in C language, the term "constant" refers to literal constants (like 1, 'a', 0xFF and so on), enum members, and results of such operators as sizeof. Const-qualified objects (of any type) are not constants in C language terminology. They cannot be used in initializers of objects with static storage duration, regardless of their type.

For example, this is NOT a constant

const int N = 5; /* `N` is not a constant in C */

The above N would be a constant in C++, but it is not a constant in C. So, if you try doing

static int j = N; /* ERROR */

you will get the same error: an attempt to initialize a static object with a non-constant.

This is the reason why, in C language, we predominantly use #define to declare named constants, and also resort to #define to create named aggregate initializers.

A static variable declared in a header file outside of the class would be file-scoped in every .c file which includes the header. That means separate copy of a variable with same name is accessible in each of the .c files where you include the header file.

A static class variable on the other hand is class-scoped and the same static variable is available to every compilation unit that includes the header containing the class with static variable.

I used this format - but...I found I had to run it three or more times to get it to actually change every instance which I found extremely strange. Running it once would change some in each file but not all. Running exactly the same string two-four times would catch all instances.

find . -type f -name '*.txt' -exec sed -i '' s/thistext/newtext/ {} +

If all you want is to invoke foo, and you prefer to propagate the exception as is (without wrapping), you can also just use Java's for loop instead (after turning the Stream into an Iterable with some trickery):

for (A a : (Iterable<A>) as::iterator) {
   a.foo();
}

This is, at least, what I do in my JUnit tests, where I don't want to go through the trouble of wrapping my checked exceptions (and in fact prefer my tests to throw the unwrapped original ones)

Assuming Column A contains the values you want to find single unique instance of, and has a Heading row I used the following formula. If you wanted it to scale with an unpredictable number of rows, you could replace A772 (where my data ended) with =ADDRESS(COUNTA(A:A),1).

=IF(COUNTIF(A5:$A$772,A5)=1,A5,"")

This will display the unique value at the LAST instance of each value in the column and doesn't assume any sorting. It takes advantage of the lack of absolutes to essentially have a decreasing "sliding window" of data to count. When the countif in the reduced window is equal to 1, then that row is the last instance of that value in the column.

You will not able to test the app using the Google-Play-Service library in emulator. In order to test that app in emulator you need to install some system framework in your emulator to make it work.

Refer the above answer to install Google play service on your emulator.

If you want to know the location of you NPM packages, you should:

which npm // locate a program file in the user's path SEE man which
// OUTPUT SAMPLE
/usr/local/bin/npm
la /usr/local/bin/npm // la: aliased to ls -lAh SEE which la THEN man ls
lrwxr-xr-x  1 t04435  admin    46B 18 Sep 10:37 /usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js

So given that npm is a NODE package itself, it is installed in the same location as other packages(EUREKA). So to confirm you should cd into node_modules and list the directory.

cd /usr/local/lib/node_modules/
ls
#SAMPLE OUTPUT
@angular npm .... all global npm packages installed

OR

npm root -g

As per @anthonygore 's comment

Assuming the submodule's repository does contain a commit you want to use (unlike the commit that is referenced from current state of the super-project), there are two ways to do it.

The first requires you to already know the commit from the submodule that you want to use. It works from the “inside, out” by directly adjusting the submodule then updating the super-project. The second works from the “outside, in” by finding the super-project's commit that modified the submodule and then reseting the super-project's index to refer to a different submodule commit.

Inside, Out

If you already know which commit you want the submodule to use, cd to the submodule, check out the commit you want, then git add and git commit it back in the super-project.

Example:

$ git submodule update
fatal: reference is not a tree: e47c0a16d5909d8cb3db47c81896b8b885ae1556
Unable to checkout 'e47c0a16d5909d8cb3db47c81896b8b885ae1556' in submodule path 'sub'

Oops, someone made a super-project commit that refers to an unpublished commit in the submodule sub. Somehow, we already know that we want the submodule to be at commit 5d5a3ee314476701a20f2c6ec4a53f88d651df6c. Go there and check it out directly.

Checkout in the Submodule

$ cd sub
$ git checkout 5d5a3ee314476701a20f2c6ec4a53f88d651df6c
Note: moving to '5d5a3ee314476701a20f2c6ec4a53f88d651df6c' which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 5d5a3ee... quux
$ cd ..

Since we are checking out a commit, this produces a detached HEAD in the submodule. If you want to make sure that the submodule is using a branch, then use git checkout -b newbranch <commit> to create and checkout a branch at the commit or checkout the branch that you want (e.g. one with the desired commit at the tip).

Update the Super-project

A checkout in the submodule is reflected in the super-project as a change to the working tree. So we need to stage the change in the super-project's index and verify the results.

$ git add sub

Check the Results

$ git submodule update
$ git diff
$ git diff --cached
diff --git c/sub i/sub

+Subproject commit 5d5a3ee314476701a20f2c6ec4a53f88d651df6c

The submodule update was silent because the submodule is already at the specified commit. The first diff shows that the index and worktree are the same. The third diff shows that the only staged change is moving the sub submodule to a different commit.

Commit

git commit

This commits the fixed-up submodule entry.

Outside, In

If you are not sure which commit you should use from the submodule, you can look at the history in the superproject to guide you. You can also manage the reset directly from the super-project.

$ git submodule update
fatal: reference is not a tree: e47c0a16d5909d8cb3db47c81896b8b885ae1556

This is the same situation as above. But this time we will focus on fixing it from the super-project instead of dipping into the submodule.

+Subproject commit 5d5a3ee314476701a20f2c6ec4a53f88d651df6c

OK, it looks like it went bad in ce5d37c, so we will restore the submodule from its parent (ce5d37c~).

Alternatively, you can take the submodule's commit from the patch text (5d5a3ee314476701a20f2c6ec4a53f88d651df6c) and use the above “inside, out” process instead.

Checkout in the Super-project

$ git checkout ce5d37c~ -- sub

This reset the submodule entry for sub to what it was at commit ce5d37c~ in the super-project.

Update the Submodule

$ git submodule update
Submodule path 'sub': checked out '5d5a3ee314476701a20f2c6ec4a53f88d651df6c'

The submodule update went OK (it indicates a detached HEAD).

Check the Results

$ git diff ce5d37c~ -- sub
$ git diff
$ git diff --cached
diff --git c/sub i/sub

The first diff shows that sub is now the same in ce5d37c~. The second diff shows that the index and worktree are the same. The third diff shows the only staged change is moving the sub submodule to a different commit.

Commit

git commit

This commits the fixed-up submodule entry.

You can also do it with jQuery:

var options = ["1", "2", "3", "4", "5"];
$('#select').empty();
$.each(options, function(i, p) {
    $('#select').append($('<option></option>').val(p).html(p));
});

"tty" originally meant "teletype" and "pty" means "pseudo-teletype".

In UNIX, /dev/tty* is any device that acts like a "teletype", ie, a terminal. (Called teletype because that's what we had for terminals in those benighted days.)

A pty is a pseudotty, a device entry that acts like a terminal to the process reading and writing there, but is managed by something else. They first appeared (as I recall) for X Window and screen and the like, where you needed something that acted like a terminal but could be used from another program.

I know this is literally a year later, but I figured I'd share. I was trying to do the same thing and came across this solution that worked for me. We set a max width for the entire table, then worked with the cell sizes for the desired effect.

Put the table in its own div, then set the width, min-width, and/or max-width of the div as desired for the entire table. Then, you can work and set width and min-widths for other cells, and max width for the div effectively working around and backwards to achieve the max width we wanted.

#tablediv {
    width:90%;
    min-width:800px
    max-width:1500px;
}

.tdleft {
    width:20%;
    min-width:200px;
}

<div id="tablediv">
  <table width="100%" border="1">
    <tr>
      <td class="tdleft">Test</td>
      <td>A long string blah blah blah</td>
    </tr>
  </table>
</div>

Admittedly, this does not give you a "max" width of a cell per se, but it does allow some control that might work in-lieu of such an option. Not sure if it will work for your needs. I know it worked for our situation where we want the navigation side in the page to scale up and down to a point but for all the wide screens these days.

Yes Jython does this, but it may or may not be what you want

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

Some given answers don't have in consideration the current day!

Here it is my proposal.

$var = "2010-01-21 00:00:00.0"
$given_date = new \DateTime($var);

if ($given_date == new \DateTime('today')) {
  //today
}

if ($given_date < new \DateTime('today')) {
  //past
}

if ($given_date > new \DateTime('today')) {
  //future
}

thePlayers[i] = new Player(i); I just deleted the i inside Player(i); and it worked.

so the code line should be:

thePlayers[i] = new Player9();

If you change your function definition to use a variable instead:

var get_page = func(url string) string {
    ...
}

You can override it in your tests:

func TestDownloader(t *testing.T) {
    get_page = func(url string) string {
        if url != "expected" {
            t.Fatal("good message")
        }
        return "something"
    }
    downloader()
}

Careful though, your other tests might fail if they test the functionality of the function you override!

The Go authors use this pattern in the Go standard library to insert test hooks into code to make things easier to test:

• https://golang.org/src/net/hook.go
• https://golang.org/src/net/dial.go#L248
• https://golang.org/src/net/dial_test.go#L701

spans are by default displayed inline, which means they don't have a height and width.

Try adding a display: block to your span.

You can use a regular expresion to for example replace all non-alphanumeric characters with commas:

s = Regex.Replace(s, "[^0-9A-Za-z]+", ",");

Note: The + after the set will make it replace each group of non-alphanumeric characters with a comma. If you want to replace each character with a comma, just remove the +.

JSmooth .exe wrapper

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your Java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a website.

JSmooth provides a variety of wrappers for your java application, each of them having their own behavior: Choose your flavor!

JarToExe 1.8 Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe on their website:

Can generate “Console”, “Windows GUI”, “Windows Service” three types of .exe files.

Generated .exe files can add program icons and version information. Generated .exe files can encrypt and protect java programs, no temporary files will be generated when the program runs.

Generated .exe files provide system tray icon support. Generated .exe files provide record system event log support. Generated windows service .exe files are able to install/uninstall itself, and support service pause/continue.

• New release of x64 version, can create 64 bits executives. (May 18, 2008)
• Both wizard mode and command line mode supported. (May 18, 2008)
• Download: http://www.brothersoft.com/jartoexe-75019.html

Executor

Package your Java application as a jar, and Executor will turn the jar into a Windows .exe file, indistinguishable from a native application. Simply double-clicking the .exe file will invoke the Java Runtime Environment and launch your application.

Create the Button and add it to Form.Controls list to display it on your form:

Button buttonOk = new Button();
buttonOk.Location = new Point(295, 45);  //or what ever position you want it to give
buttonOk.Text = "OK"; //or what ever you want to write over it
buttonOk.Click += new EventHandler(buttonOk_Click);
this.Controls.Add(buttonOk); //here you add it to the Form's Controls list

Create the button click method here:

void buttonOk_Click(object sender, EventArgs e)
        {
            MessageBox.Show("clicked");
            this.Close(); //all your choice to close it or remove this line
        }

Try this:

& "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe" PCNAME

To PowerShell a string "..." is just a string and PowerShell evaluates it by echoing it to the screen. To get PowerShell to execute the command whose name is in a string, you use the call operator &.

The error is a stack overflow. That should ring a bell on this site, right? It occurs because a call to poruszanie results in another call to poruszanie, incrementing the recursion depth by 1. The second call results in another call to the same function. That happens over and over again, each time incrementing the recursion depth.

Now, the usable resources of a program are limited. Each function call takes a certain amount of space on top of what is called the stack. If the maximum stack height is reached, you get a stack overflow error.

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

If you are using lodash or underscore.js, here is a simple solution:

var obj = {name: 'John', age: null};

var compacted = _.pickBy(obj);

This will only work with lodash 4, pre lodash 4 or underscore.js, use _.pick(obj, _.identity);

You can use org.apache.commons.lang.time.DateUtils to make it cleaner:

(firstDate.getTime() - secondDate.getTime()) / DateUtils.MILLIS_PER_SECOND

Building on Billy Jakes awnser, I made a fully dynamic mock method with an out parameter. I'm posting this here for anyone who finds it usefull.

// Define a delegate with the params of the method that returns void.
delegate void methodDelegate(int x, out string output);

// Define a variable to store the return value.
bool returnValue;

// Mock the method: 
// Do all logic in .Callback and store the return value.
// Then return the return value in the .Returns
mockHighlighter.Setup(h => h.SomeMethod(It.IsAny<int>(), out It.Ref<int>.IsAny))
  .Callback(new methodDelegate((int x, out int output) =>
  {
    // do some logic to set the output and return value.
    output = ...
    returnValue = ...
  }))
  .Returns(() => returnValue);

As Matt has said, use Console.Write. I would also recommend explicitly flushing the output, however - I believe WriteLine does this automatically, but I'd seen oddities when just using Console.Write and then waiting. So Matt's code becomes:

Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();

Here is a trick that some may find useful:

For Select queries (only), you can create Views, especially where you find yourself running the same select queries over and over e.g. in production support scenarios.

The main advantages of creating Views are:

• they are resident within the database and therefore permanent
• they can be shared across sessions and users
• they provide all the usual benefits of working with tables
• they can be queried further, just like tables e.g. to filter down the results further
• as they are stored as queries under the hood, they do not add any overheads.

You can create a view easily by simply clicking the "Create view" link at the bottom of the results table display.

    <activity
        android:name="MyBookActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.ALTERNATIVE" />
        </intent-filter>
    </activity>

where is your dot before MyBookActivity?

For Kotlin users (activity as AppCompatActivity).supportActionBar?.show()

If you're on a shared server like me the host said it was a result of hitting memory limits, so they kill scripts which results in the "Premature end of script headers" seen in this error. They referred me to this:

Given an increase in memory, the issues went. I think a backup plugin Updraft on wordpress was perhaps over zealous in its duty/settings.

Try LinkedHashMap, sample:

Map<String,String> map = new LinkedHashMap<String,String>();    
map.put('1','linked');map.put('1','hash');    
map.put('2','map');map.put('3','java');.. 

output:

keys: 1,1,2,3

values: linked,hash, map, java

The swipe gesture detector code above is very useful! You may however wish to make this solution density agnostic by using the following relative values (REL_SWIPE) rather than the absolute values (SWIPE_)

DisplayMetrics dm = getResources().getDisplayMetrics();

int REL_SWIPE_MIN_DISTANCE = (int)(SWIPE_MIN_DISTANCE * dm.densityDpi / 160.0f);
int REL_SWIPE_MAX_OFF_PATH = (int)(SWIPE_MAX_OFF_PATH * dm.densityDpi / 160.0f);
int REL_SWIPE_THRESHOLD_VELOCITY = (int)(SWIPE_THRESHOLD_VELOCITY * dm.densityDpi / 160.0f);

I've used an empty :after element and decorated one border on it. You can even use CSS transforms to rotate it for a slanted line. Result: pure CSS, no extra HTML elements! Downside: doesn't wrap across multiple lines, although IMO you shouldn't use strikethrough on large blocks of text anyway.

s,_x000D_
strike {_x000D_
  text-decoration: none;_x000D_
  /*we're replacing the default line-through*/_x000D_
  position: relative;_x000D_
  display: inline-block;_x000D_
  /* keeps it from wrapping across multiple lines */_x000D_
}_x000D_
_x000D_
s:after,_x000D_
strike:after {_x000D_
  content: "";_x000D_
  /* required property */_x000D_
  position: absolute;_x000D_
  bottom: 0;_x000D_
  left: 0;_x000D_
  border-top: 2px solid red;_x000D_
  height: 45%;_x000D_
  /* adjust as necessary, depending on line thickness */_x000D_
  /* or use calc() if you don't need to support IE8: */_x000D_
  height: calc(50% - 1px);_x000D_
  /* 1px = half the line thickness */_x000D_
  width: 100%;_x000D_
  transform: rotateZ(-4deg);_x000D_
}

<p>Here comes some <strike>strike-through</strike> text!</p>

As an alternative to using clip you could also use {border-radius: 0.0001px} on a parent element. It works not only with absolute/fixed positioned elements.

The use of variables that have yet to been defined or set (implicitly or explicitly) is often a bad thing in any language, since it tends to indicate that the logic of the program hasn't been thought through properly, and is likely to result in unpredictable behaviour.

If you need to do it in Python, the following trick, which is similar to yours, will ensure that a variable has some value before use:

try:
    myVar
except NameError:
    myVar = None      # or some other default value.

# Now you're free to use myVar without Python complaining.

However, I'm still not convinced that's a good idea - in my opinion, you should try to refactor your code so that this situation does not occur.

//for excluding zero
public class SmallestInt {

    public static void main(String[] args) {

        Scanner input= new Scanner(System.in);

        System.out.println("enter number");
        int val=input.nextInt();
        int min=val;

        //String notNull;

        while(input.hasNextInt()==true)
        {
            val=input.nextInt();
            if(val<min)
                min=val;
        }
        System.out.println("min is: "+min);
    }
}

$.params = window.location.href.split("/"); $.params[$.params.length-1];

You can split based on your query string separator

I meet the same questions in 3.7 on ubuntu 12.04. My Os use a proxy 127.0.0.1,and the eclipse use another proxy 192.168.1.1.

I read the .log for info. It says !MESSAGE System property http.proxyHost is set to 127.0.0.1 but should be 192.168.1.1.

so I change the eclipse net work setting to the same as the system . At last,it works.

Use this jQuery extension by James Padoley

In my case the problem was that I started to create an MVC Alloy sample project from scratch in using Visual Studio/Episerver extension and it worked fine when executed using local Visual studio iis express. However by default it points the sql database to LocalDB and when I deployed the site to local IIS it started giving errors some of the initial errors I resolved by: 1.adding the local site url binding to C:/Windows/System32/drivers/etc/hosts 2. Then by editing the application.config found the file location by right clicking on IIS express in botton right corner of the screen when running site using Visual studio and added binding there for local iis url. 3. Finally I was stuck with "unable to access database errors" for which I created a blank new DB in Sql express and changed connection string in web config to point to my new DB and then in package manager console (using Visual Studio) executed Episerver DB commands like - 1. initialize-epidatabase 2. update-epidatabase 3. Convert-EPiDatabaseToUtc

Double check projects .net versions. Projects that referenced each other with different .net versions causes problems.

There are a couple of ways:

If you want to use raw Javascript (without a helper like JQuery), then you could do something like:

var link = "http://google.com";
var element = document.createElement("a");
element.setAttribute("href", link);
element.innerHTML = "your text";

// and append it to where you'd like it to go:
document.body.appendChild(element);

The other method is to write the link directly into the document:

document.write("<a href='" + link + "'>" + text + "</a>");

This depends on the shell you prefer to use.

If you are using the cmd shell on Windows then the following should work:

FOR /F "tokens=*" %%G IN ('DIR /B /AD /S bin') DO RMDIR /S /Q "%%G"
FOR /F "tokens=*" %%G IN ('DIR /B /AD /S obj') DO RMDIR /S /Q "%%G"

If you are using a bash or zsh type shell (such as git bash or babun on Windows or most Linux / OS X shells) then this is a much nicer, more succinct way to do what you want:

find . -iname "bin" | xargs rm -rf
find . -iname "obj" | xargs rm -rf

and this can be reduced to one line with an OR:

find . -iname "bin" -o -iname "obj" | xargs rm -rf

Note that if your directories of filenames contain spaces or quotes, find will send those entries as-is, which xargs may split into multiple entries. If your shell supports them, -print0 and -0 will work around this short-coming, so the above examples become:

find . -iname "bin" -print0 | xargs -0 rm -rf
find . -iname "obj" -print0 | xargs -0 rm -rf

and:

find . -iname "bin" -o -iname "obj" -print0 | xargs -0 rm -rf

If you are using Powershell then you can use this:

Get-ChildItem .\ -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

as seen in Robert H's answer below - just make sure you give him credit for the powershell answer rather than me if you choose to up-vote anything :)

It would of course be wise to run whatever command you choose somewhere safe first to test it!

If I understand correctly, you want only the error for the failing step to show, right?

That should be as simple as changing the failure case of the first promise to this:

step(1).then(function (response) {
    step(2);
}, function (response) {
    stepError(1);
    return response;
}).then( ... )

By returning $q.reject() in the first step's failure case, you're rejecting that promise, which causes the errorCallback to be called in the 2nd then(...).

I use to ZipDiff lib (have both Java and ant API).

The standard mocking frameworks are creating proxy classes. This is the reason why they are technically limited to interfaces and virtual methods.

If you want to mock 'normal' methods as well, you need a tool that works with instrumentation instead of proxy generation. E.g. MS Moles and Typemock can do that. But the former has a horrible 'API', and the latter is commercial.

I used the header("Access-Control-Allow-Origin: *"); method but still received the CORS error. It turns out that the PHP script that was being requested had an error in it (I had forgotten to add a period (.) when concatenating two variables). Once I fixed that typo, it worked!

So, It seems that the remote script being called cannot have errors within it.

1. In the Server's tab in Eclipse, Stop the Tomcat server

2. Right-click the server and select "Clean..."

3. Right-click the server again and select "Clean Tomcat Work Directory..."

4. In the Eclipse, select the top-level menu option, Project > Clean ...

5. Be sure your project is selected and click Ok

6. Restart Eclipse

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

See if you have a file located under /etc/my.cnf. If so, it should tell you where the data directory is.

For example:

[mysqld]
set-variable=local-infile=0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
...

My guess is that your mysql might be installed to /usr/local/mysql-XXX.

You may find these MySQL reference manual links useful:

• Installing MySQL 5.7 on MacOS
• Installing MySQL 5.6 on MacOS

The easiest way for me is doing this:

from unittest.mock import Mock, patch

def test():
    datetime_mock = Mock(wraps=datetime.datetime)
    datetime_mock.now.return_value = datetime.datetime(1999, 1, 1)
    with patch('datetime.datetime', new=datetime_mock):
        assert datetime.datetime.now() == datetime.datetime(1999, 1, 1)

CAUTION for this solution: all functionality from datetime module from the target_module will stop working.

The rvest along with xml2 is another popular package for parsing html web pages.

library(rvest)
theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
file<-read_html(theurl)
tables<-html_nodes(file, "table")
table1 <- html_table(tables[4], fill = TRUE)

The syntax is easier to use than the xml package and for most web pages the package provides all of the options ones needs.

I would recommend using rgba(255,255,255,0) because broken (newest) safari thinks that if you are using transparent or rgba(0,0,0,0) in linear-gradent you really mean gray, For more info please head to - What happens in Safari with the transparent color?

Is there any way to dump the call stack in a running process in C or C++ every time a certain function is called?

You can use a macro function instead of return statement in the specific function.

For example, instead of using return,

int foo(...)
{
    if (error happened)
        return -1;

    ... do something ...

    return 0
}

You can use a macro function.

#include "c-callstack.h"

int foo(...)
{
    if (error happened)
        NL_RETURN(-1);

    ... do something ...

    NL_RETURN(0);
}

Whenever an error happens in a function, you will see Java-style call stack as shown below.

Error(code:-1) at : so_topless_ranking_server (sample.c:23)
Error(code:-1) at : nanolat_database (sample.c:31)
Error(code:-1) at : nanolat_message_queue (sample.c:39)
Error(code:-1) at : main (sample.c:47)

The ThreadPoolExecutor class is the base implementation for the executors that are returned from many of the Executors factory methods. So let's approach Fixed and Cached thread pools from ThreadPoolExecutor's perspective.

ThreadPoolExecutor

The main constructor of this class looks like this:

public ThreadPoolExecutor(
                  int corePoolSize,
                  int maximumPoolSize,
                  long keepAliveTime,
                  TimeUnit unit,
                  BlockingQueue<Runnable> workQueue,
                  ThreadFactory threadFactory,
                  RejectedExecutionHandler handler
)

Core Pool Size

The corePoolSize determines the minimum size of the target thread pool. The implementation would maintain a pool of that size even if there are no tasks to execute.

Maximum Pool Size

The maximumPoolSize is the maximum number of threads that can be active at once.

After the thread pool grows and becomes bigger than the corePoolSize threshold, the executor can terminate idle threads and reach to the corePoolSize again. If allowCoreThreadTimeOut is true, then the executor can even terminate core pool threads if they were idle more than keepAliveTime threshold.

So the bottom line is if threads remain idle more than keepAliveTime threshold, they may get terminated since there is no demand for them.

Queuing

What happens when a new task comes in and all core threads are occupied? The new tasks will be queued inside that BlockingQueue<Runnable> instance. When a thread becomes free, one of those queued tasks can be processed.

There are different implementations of the BlockingQueue interface in Java, so we can implement different queuing approaches like:

1. Bounded Queue: New tasks would be queued inside a bounded task queue.

2. Unbounded Queue: New tasks would be queued inside an unbounded task queue. So this queue can grow as much as the heap size allows.

3. Synchronous Handoff: We can also use the SynchronousQueue to queue the new tasks. In that case, when queuing a new task, another thread must already be waiting for that task.

Work Submission

Here's how the ThreadPoolExecutor executes a new task:

1. If fewer than corePoolSize threads are running, tries to start a new thread with the given task as its first job.
2. Otherwise, it tries to enqueue the new task using the BlockingQueue#offer method. The offer method won't block if the queue is full and immediately returns false.
3. If it fails to queue the new task (i.e. offer returns false), then it tries to add a new thread to the thread pool with this task as its first job.
4. If it fails to add the new thread, then the executor is either shut down or saturated. Either way, the new task would be rejected using the provided RejectedExecutionHandler.

The main difference between the fixed and cached thread pools boils down to these three factors:

1. Core Pool Size
2. Maximum Pool Size
3. Queuing

+-----------+-----------+-------------------+---------------------------------+
| Pool Type | Core Size |    Maximum Size   |         Queuing Strategy        |
+-----------+-----------+-------------------+---------------------------------+
|   Fixed   | n (fixed) |     n (fixed)     | Unbounded `LinkedBlockingQueue` |
+-----------+-----------+-------------------+---------------------------------+
|   Cached  |     0     | Integer.MAX_VALUE |        `SynchronousQueue`       |
+-----------+-----------+-------------------+---------------------------------+

Fixed Thread Pool

public static ExecutorService newFixedThreadPool(int nThreads) {
    return new ThreadPoolExecutor(nThreads, nThreads,
                                  0L, TimeUnit.MILLISECONDS,
                                  new LinkedBlockingQueue<Runnable>());
}

As you can see:

• The thread pool size is fixed.
• If there is high demand, it won't grow.
• If threads are idle for quite some time, it won't shrink.
• Suppose all those threads are occupied with some long-running tasks and the arrival rate is still pretty high. Since the executor is using an unbounded queue, it may consume a huge part of the heap. Being unfortunate enough, we may experience an OutOfMemoryError.

When should I use one or the other? Which strategy is better in terms of resource utilization?

A fixed-size thread pool seems to be a good candidate when we're going to limit the number of concurrent tasks for resource management purposes.

For example, if we're going to use an executor to handle web server requests, a fixed executor can handle the request bursts more reasonably.

For even better resource management, it's highly recommended to create a custom ThreadPoolExecutor with a bounded BlockingQueue<T> implementation coupled with reasonable RejectedExecutionHandler.

Cached Thread Pool

Here's how the Executors.newCachedThreadPool() works:

public static ExecutorService newCachedThreadPool() {
    return new ThreadPoolExecutor(0, Integer.MAX_VALUE,
                                  60L, TimeUnit.SECONDS,
                                  new SynchronousQueue<Runnable>());
}

As you can see:

• The thread pool can grow from zero threads to Integer.MAX_VALUE. Practically, the thread pool is unbounded.
• If any thread is idle for more than 1 minute, it may get terminated. So the pool can shrink if threads remain too much idle.
• If all allocated threads are occupied while a new task comes in, then it creates a new thread, as offering a new task to a SynchronousQueue always fails when there is no one on the other end to accept it!

When should I use one or the other? Which strategy is better in terms of resource utilization?

Use it when you have a lot of predictable short-running tasks.

If you want to stick to just HTML/CSS on a form, another option is to use a button. Style it and set the disabled attribute.

E.g. http://jsfiddle.net/cFTxH/1/

words = x.split("_")
for word in words:
    if word[0] == word[0].upper() and word[1:] == word[1:].lower():
        print word, "is conformant"
    else:
        print word, "is non conformant"

Simply do the following:

1. Open your .sql file with Notepad or Notepad ++

2. Find InnoDB and Replace all (around 87) with MyISAM

3. Save and now you can import your database with out error.

You need to add type assertion .(string). It is necessary because the map is of type map[string]interface{}:

host := arguments["<host>"].(string) + ":" + arguments["<port>"].(string)

Latest version of Docopt returns Opts object that has methods for conversion:

host, err := arguments.String("<host>")
port, err := arguments.String("<port>")
host_port := host + ":" + port

Answers provided here as which camera api to use are wrong. Or better to say they are insufficient.

Some phones (for example Samsung Galaxy S6) could be above api level 21 but still may not support Camera2 api.

CameraCharacteristics mCameraCharacteristics = mCameraManager.getCameraCharacteristics(mCameraId);
Integer level = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
if (level == null || level == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
    return false;
}

CameraManager class in Camera2Api has a method to read camera characteristics. You should check if hardware wise device is supporting Camera2 Api or not.

But there are more issues to handle if you really want to make it work for a serious application: Like, auto-flash option may not work for some devices or battery level of the phone might create a RuntimeException on Camera or phone could return an invalid camera id and etc.

So best approach is to have a fallback mechanism as for some reason Camera2 fails to start you can try Camera1 and if this fails as well you can make a call to Android to open default Camera for you.

This is because Java Generics are implemented with Type Erasure.

Your methods would be translated, at compile time, to something like:

Method resolution occurs at compile time and doesn't consider type parameters. (see erickson's answer)

void add(Set ii);
void add(Set ss);

Both methods have the same signature without the type parameters, hence the error.

I would suggest dateutil:

import dateutil.parser
dateutil.parser.parse("01/12/2011", dayfirst=True).timestamp()

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

Yes, this is possible by using worksheet events:

In the Visual Basic Editor open the worksheet you're interested in (i.e. "BigBoard") by double clicking on the name of the worksheet in the tree at the top left. Place the following code in the module:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Intersect(Target, Me.Range("D2")) Is Nothing Then Exit Sub
        Application.EnableEvents = False 'to prevent endless loop
        On Error Goto Finalize 'to re-enable the events      
        MsgBox "You changed THE CELL!"
    End If
Finalize:        
    Application.EnableEvents = True
End Sub

To find table dependencies you can use the sys.sql_expression_dependencies catalog view:

SELECT 
referencing_object_name = o.name, 
referencing_object_type_desc = o.type_desc, 
referenced_object_name = referenced_entity_name, 
referenced_object_type_desc =so1.type_desc 
FROM sys.sql_expression_dependencies sed 
INNER JOIN sys.views o ON sed.referencing_id = o.object_id 
LEFT OUTER JOIN sys.views so1 ON sed.referenced_id =so1.object_id 
WHERE referenced_entity_name = 'Person'  

You can also try out ApexSQL Search a free SSMS and VS add-in that also has the View Dependencies feature. The View Dependencies feature has the ability to visualize all SQL database objects’ relationships, including those between encrypted and system objects, SQL server 2012 specific objects, and objects stored in databases encrypted with Transparent Data Encryption (TDE)

Disclaimer: I work for ApexSQL as a Support Engineer

The fundamental difference between include and import is that you must use import to refer to declarations or definitions that are in a different target namespace and you must use include to refer to declarations or definitions that are (or will be) in the same target namespace.

Yes, in AndroidManifest.xml, declare your Activity like so: <activity ... android:screenOrientation="landscape" .../>

Use the Pandas library to create a dataframe of the csv data.
Name the fields either by including them in the csv file's first line or in code by using the dataframe's columns method.
Then create a list of model instances.
Finally use the django method .bulk_create() to send your list of model instances to the database table.

The read_csv function in pandas is great for reading csv files and gives you lots of parameters to skip lines, omit fields, etc.

import pandas as pd

tmp_data=pd.read_csv('file.csv',sep=';')
#ensure fields are named~ID,Product_ID,Name,Ratio,Description
#concatenate name and Product_id to make a new field a la Dr.Dee's answer
products = [
    Product(
        name = tmp_data.ix[row]['Name'] 
        description = tmp_data.ix[row]['Description'],
        price = tmp_data.ix[row]['price'],
    )
    for row in tmp_data['ID']
]
Product.objects.bulk_create(products)

I was using the answer by mmrs151 but saving each row (instance) was very slow and any fields containing the delimiting character (even inside of quotes) were not handled by the open() -- line.split(';') method.

Pandas has so many useful caveats, it is worth getting to know

It means: "A class that you use needs another class that is not on the classpath." You should make sure (as Harry Joy suggests) to add the required jar to the classpath.

pass in this in the inline click handler

<a href="123.com" onclick="click123(this);">link</a>

or use event.target in the function (according to the W3C DOM Level 2 Event model)

function click123(event)
{
    var a = event.target;
}

But of course, IE is different, so the vanilla JavaScript way of handling this is

function doSomething(e) {
    var targ;
    if (!e) var e = window.event;
    if (e.target) targ = e.target;
    else if (e.srcElement) targ = e.srcElement;
    if (targ.nodeType == 3) // defeat Safari bug
        targ = targ.parentNode;
}

or less verbose

function doSomething(e) {

    e = e || window.event;
    var targ = e.target || e.srcElement || e;
    if (targ.nodeType == 3) targ = targ.parentNode; // defeat Safari bug
}

where e is the event object that is passed to the function in browsers other than IE.

If you're using jQuery though, I would strongly encourage unobtrusive JavaScript and use jQuery to bind event handlers to elements.

In my case it got fixed by increasing the extended memory of eclipse, by changing the value of -Xmx768m in eclipse.ini

If any background task runs more than 10 minutes,then the task will be suspended and code block specified with beginBackgroundTaskWithExpirationHandler is called to clean up the task. background remaining time can be checked with [[UIApplication sharedApplication] backgroundTimeRemaining]. Initially when the App is in foreground backgroundTimeRemaining is set to bigger value. When the app goes to background, you can see backgroundTimeRemaining value decreases from 599.XXX ( 1o minutes). once the backgroundTimeRemaining becomes ZERO, the background task will be suspended.

        //1)Creating iOS Background Task
        __block UIBackgroundTaskIdentifier background_task;
        background_task = [application beginBackgroundTaskWithExpirationHandler:^ {

               //remaining background time reaches ZERO.
          }];


        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
            //### background task starts

            //#### background task ends
        });

        //2)Making background task Asynchronous

            __block UIBackgroundTaskIdentifier background_task;
            background_task = [application beginBackgroundTaskWithExpirationHandler:^ {

                //Clean up code. Tell the system that we are done.
                [application endBackgroundTask: background_task];
                background_task = UIBackgroundTaskInvalid;
            }];


        **//Putting All together**
            //To make the code block asynchronous
            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

                //### background task starts
                NSLog(@"Running in the background\n");
                while(TRUE)
                {
                    NSLog(@"Background time Remaining: %f",[[UIApplication sharedApplication] backgroundTimeRemaining]);
                    [NSThread sleepForTimeInterval:1]; //wait for 1 sec
                }
                //#### background task ends

                //Clean up code. Tell the system that we are done.
                [application endBackgroundTask: background_task];
                background_task = UIBackgroundTaskInvalid; 
            });

No there actually is no way to prevent a user from doing a particular task. But you can always take measures! The image sharing websites have a huge team of developers working day and night to create such an algorithm where you prevent user from saving the image files.

First way

Try this:

$('img').mousedown(function (e) {
  if(e.button == 2) { // right click
    return false; // do nothing!
  }
}

So the user won't be able to click on the Save Image As... option from the menu and in turn he won't get a chance to save the image.

Second way

Other way is to use background-image. This way, the user won't be able to right click and Save the Image As... But he can still see the resources in the Inspector.

Third way

Even I am new to this one, few days ago I was surfing Flickr when I tried to right click, it did not let me do a thing. Which in turn was the first method that I provided you with. Then I tried to go and see the inspector, there I found nothing. Why? Since they were using background-image and at the same time they were using data:imagesource as its location.

Which was amazing for me too. You can precvent user from saving image files this way easily.

It is known as Data URI Scheme: http://en.wikipedia.org/wiki/Data_URI_scheme

Note

Please remember brother, when you're letting a user surf your website you're giving him READ permissions on the server side so he can read all the files without any problem. The same is the issue with image files. He can read the image files, and then he can easily save them. He downloads the images on the first place when he is surfing your website. So there is not an issue for him to save them on his disk.

If splitting very large files, the solution I found is an adaptation from this, with PowerShell "embedded" in a batch file. This works fast, as opposed to many other things I tried (I wouldn't know about other options posted here).

The way to use mysplit.bat below is

mysplit.bat <mysize> 'myfile'

Note: The script was intended to use the first argument as the split size. It is currently hardcoded at 100Mb. It should not be difficult to fix this.

Note 2: The filname should be enclosed in single quotes. Other alternatives for quoting apparently do not work.

Note 3: It splits the file at given number of bytes, not at given number of lines. For me this was good enough. Some lines of code could be probably added to complete each chunk read, up to the next CR/LF. This will split in full lines (not with a constant number of them), with no sacrifice in processing time.

You could also use a block

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [object method]; 
});

Most of time you will want to use dispatch_get_main_queue, although if there is no UI in the method you could use a global queue.

Edit:

Swift 3 version:

DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
    object.method()
}

Equally, DispatchQueue.global().asyncAfter(... might also be a good option.

Excel 2013 can do Count distinct in pivots. If no access to 2013, and it's a smaller amount of data, I make two copies of the raw data, and in copy b, select both columns and remove duplicates. Then make the pivot and count your column b.

You may need to restart your adb via Android Studio (do it twice for good measure).

You can use this to continue using the type Date and a more legible code, if you preffer:

import org.apache.commons.lang.time.DateUtils;
...
Date yourDate = DateUtils.addDays(new Date(), *days here*);

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

Below is the perfect one for mentioned requirement :

^[0-9]{1,3}(,[0-9]{3})*(([\\.,]{1}[0-9]*)|())$

If you have the column and the sequence, you first need to populate a new key for all the existing rows. Assuming you don't care which key is assigned to which row

UPDATE table_name
   SET new_pk_column = sequence_name.nextval;

Once that's done, you can create the primary key constraint (this assumes that either there is no existing primary key constraint or that you have already dropped the existing primary key constraint)

ALTER TABLE table_name
  ADD CONSTRAINT pk_table_name PRIMARY KEY( new_pk_column )

If you want to generate the key automatically, you'd need to add a trigger

CREATE TRIGGER trigger_name
  BEFORE INSERT ON table_name
  FOR EACH ROW
BEGIN
  :new.new_pk_column := sequence_name.nextval;
END;

If you are on an older version of Oracle, the syntax is a bit more cumbersome

CREATE TRIGGER trigger_name
  BEFORE INSERT ON table_name
  FOR EACH ROW
BEGIN
  SELECT sequence_name.nextval
    INTO :new.new_pk_column
    FROM dual;
END;

Python 3.7:

List comprehensions are faster.

Generators are more memory efficient.

As all others have said, if you're looking to scale infinite data, you'll need a generator eventually. For relatively static small and medium-sized jobs where speed is necessary, a list comprehension is best.

You can customize material styles by setting different color properties. For example custom application theme

<style name="CustomAppTheme" parent="Theme.AppCompat">
    <item name="android:textColorPrimaryDisableOnly">#00838f</item>
    <item name="colorAccent">#e91e63</item>
</style>

Custom switch theme

<style name="MySwitch" parent="@style/Widget.AppCompat.CompoundButton.Switch">
    <item name="android:textColorPrimaryDisableOnly">#b71c1c</item>
    <item name="android:colorControlActivated">#1b5e20</item>
    <item name="android:colorForeground">#f57f17</item>
    <item name="android:textAppearance">@style/TextAppearance.AppCompat</item>
</style>

You can customize switch track and switch thumb like below image by defining xml drawables. For more information http://www.zoftino.com/android-switch-button-and-custom-switch-examples

You need to declare the variables outside the function:

Public iRaw As Integer
Public iColumn As Integer

Function find_results_idle()
    iRaw = 1
    iColumn = 1

I you only want to apply the change only for one field, you could try serializing the field

class MyModel < ActiveRecord::Base
  serialize :content

  attr_accessible :content, :title
end

You need to apply DATE_FORMAT in the SELECT clause, not the WHERE clause:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

Also note that CURDATE() returns only the DATE portion of the date, so if you store create_date as a DATETIME with the time portion filled, this query will not select the today's records.

In this case, you'll need to use NOW instead:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()

I would use the numpy library, which would allow you to do this for a list of numbers as well:

from numpy import array
a = array([1, 2, 3, 4, 5, 6,])
a[a < 2]

An update. Dates of the form '2019-08-00' will trigger the same error. Adding the lines:

[mysqld]

sql_mode="NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" 

to mysql.cnf fixes this too. Inserting malformed dates now generates warnings for values out of range but does insert the data.

If you want to force the issue, you can do:

git reset --hard c14809fafb08b9e96ff2879999ba8c807d10fb07

send you back to how your git clone looked like at the time of the checkin

You can use these tools:

• PyChecker
• Pyflakes
• Pylint

Try something like this (use this.url to get the url):

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

You can use the following to pass data to view in Laravel:

public function contact($id) {
    return view('contact',compact('id'));
}

int x;
ifile >> x

while (!iFile.eof())
{  
    cerr << x << endl;        
    iFile >> x;      
}

Adding "relaxedQueryChars" attribute to the server.xml worked for me :

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="443" URIEncoding="UTF-8" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"/>

First of all: Yes you can mix jQuery with common JS :)

Best way to build up an intervall call of a function is to use setTimeout methode:

For example, if you have a function called test() and want to repeat it all 5 seconds, you could build it up like this:

function test(){
    console.log('test called');
    setTimeout(test, 5000);
}

Finally you have to trigger the function once:

$(document).ready(function(){
    test();
});

This document ready function is called automatically, after all html is loaded.

You will find much information about JavaDoc at the Documentation Comment Specification for the Standard Doclet, including the information on the

{@link package.class#member label}

tag (that you are looking for). The corresponding example from the documentation is as follows

For example, here is a comment that refers to the getComponentAt(int, int) method:

Use the {@link #getComponentAt(int, int) getComponentAt} method.

The package.class part can be ommited if the referred method is in the current class.

Other useful links about JavaDoc are:

• JavaDoc Tool Reference
• JavaDoc Guide
• How to Write Doc Comments for the Javadoc Tool

I don't really see a way to do this as-is. I think you might need to remove the overflow:hidden from div#1 and add another div within div#1 (ie as a sibling to div#2) to hold your unspecified 'content' and add the overflow:hidden to that instead. I don't think that overflow can be (or should be able to be) over-ridden.

A trailing comma in a JSON array caused my Perl 5.16 to hang, possibly because it kept backtracking. I had to add a backtrack-terminating directive:

(?<json>   \s* (?: (?&number) | (?&boolean) | (?&string) | (?&array) | (?&object) )(*PRUNE) \s* )
                                                                                   ^^^^^^^^

This way, once it identifies a construct that is not 'optional' (* or ?), it shouldn't try backtracking over it to try to identify it as something else.

Do note that PostgreSQL 9.0 (today in beta testing) will have a simple way to do that:

test=> GRANT SELECT ON ALL TABLES IN SCHEMA public TO joeuser;

Run a test.

   string coerce:          7.42296099663
   string cast:            8.05654597282
   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

$string_cast_fail->Stop();

// -----------------
print "\n";
print "string coerce:          ".$string_coerce->Elapsed()."\n";
print "string cast:            ".$string_cast->Elapsed()."\n";
print "string fail coerce:     ".$string_coerce_fail->Elapsed()."\n";
print "string fail cast:       ".$string_cast_fail->Elapsed()."\n";


class Timer {
    var $ticking = null;
    var $started_at = false;
    var $elapsed = 0;

    function Timer() {
        $this->ticking = null;
    }

    function Start() {
        $this->ticking = true;
        $this->started_at = microtime(TRUE);
    }

    function Stop() {
        if( $this->ticking )
            $this->elapsed = microtime(TRUE) - $this->started_at;
        $this->ticking = false;
    }

    function Elapsed() {
        switch( $this->ticking ) {
            case true: return "Still Running";
            case false: return $this->elapsed;
            case null: return "Not Started";
        }
    }
}

urllib went through some changes in Python3 and can now be imported from the parse submodule

>>> from urllib.parse import quote

'%22'                               

Runtime rt = Runtime.getRuntime();
rt.maxMemory()

value is b

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
am.getMemoryClass()

value is MB

I found the answer... or at least, the easiest answer (if there are multiple). When I installed the printer, I renamed it to "ICS Label Printer". Here's how to change the options to allow pass-through ZPL commands:

1. Right-click on the "ICS Label Printer" and choose "Properties".
2. On the "General" tab, click on the "Printing Preferences..." button.
3. On the "Advanced Setup" tab, click on the "Other" button.
4. Make sure there is a check in the box labeled "Enable Passthrough Mode".
5. Make sure the "Start sequence:" is "${".
6. Make sure the "End sequence:" is "}$".
7. Click on the "Close" button.
8. Click on the "OK" button.
9. Click on the "OK" button.

In my code, I just have to add "${" to the beginning of my ZPL and "}$" to the end and print it as plain text. This is with the "Windows driver for ZDesigner LP 2844-Z printer Version 2.6.42 (Build 2382)". Works like a charm!

It's a working example:

CREATE USER auto_exchange IDENTIFIED BY 123456;
GRANT RESOURCE TO auto_exchange;
GRANT CONNECT TO auto_exchange;
GRANT CREATE VIEW TO auto_exchange;
GRANT CREATE SESSION TO auto_exchange;
GRANT UNLIMITED TABLESPACE TO auto_exchange;
