For other beginners like me, who didn't find any suitable solution for this error, check the node version installed (x32, x64, x86). I have a 64-bit CPU and I've installed x86 node version, which caused the CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory error.

you don't need to pass the entire encoded string to atob method, you need to split the encoded string and pass the required string to atob method

const token= "eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJob3NzYW0iLCJUb2tlblR5cGUiOiJCZWFyZXIiLCJyb2xlIjoiQURNSU4iLCJpc0FkbWluIjp0cnVlLCJFbXBsb3llZUlkIjoxLCJleHAiOjE2MTI5NDA2NTksImlhdCI6MTYxMjkzNzA1OX0.8f0EeYbGyxt9hjggYW1vR5hMHFVXL4ZvjTA6XgCCAUnvacx_Dhbu1OGh8v5fCsCxXQnJ8iAIZDIgOAIeE55LUw"
console.log(atob(token.split(".")[1]));

If you are using six, you can try this, by which utilizing the latest Python 3 API and can run in both Python 2/3:

import six

if six.PY2:
    # FileNotFoundError is only available since Python 3.3
    FileNotFoundError = IOError
    from io import open

fname = 'index.rst'
try:
    with open(fname, "rt", encoding="utf-8") as f:
        pass
        # do_something_with_f ...
except FileNotFoundError:
    print('Oops.')

And, Python 2 support abandon is just deleting everything related to six.

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

The number one suggestion of Invalidate Caches/Restart... did not work for me nor did any of the other solutions. It ended up being that my maven repos were incorrectly set up, I fixed this by manually overriding the settings.xml and repository directory:

File -> Settings... -> Build, Execution, Deployment -> Build Tools -> Maven

Then for User settings file and Local repository, check the Override and point it to the correct settings.xml and repository directory.

Just add the following rules to the parent element:

display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */

Here's a sample demo (Resize window to see the image align)

Browser support for Flexbox nowadays is quite good.

For cross-browser compatibility for display: flex and align-items, you can add the older flexbox syntax as well:

display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

Answer from Nykakin at AskUbuntu:

You can also check Python version from code itself using platform module from standard library.

There are two functions:

• platform.python_version() (returns string).
• platform.python_version_tuple() (returns tuple).

The Python code

Create a file for example: version.py)

Easy method to check version:

import platform

print(platform.python_version())
print(platform.python_version_tuple())

You can also use the eval method:

try:
  eval("1 if True else 2")
except SyntaxError:
  raise ImportError("requires ternary support")

Run the Python file in a command line:

$ python version.py 
2.7.11
('2', '7', '11')

Copy Schema (Generate DDL) through SSMS UI

In SSMS expand your database in Object Explorer, go to Tables, right click on the table you're interested in and select Script Table As, Create To, New Query Editor Window. Do a find and replace (CTRL + H) to change the table name (i.e. put ABC in the Find What field and ABC_1 in the Replace With then click OK).

Copy Schema through T-SQL

The other answers showing how to do this by SQL also work well, but the difference with this method is you'll also get any indexes, constraints and triggers.

Copy Data

If you want to include data, after creating this table run the below script to copy all data from ABC (keeping the same ID values if you have an identity field):

set identity_insert ABC_1 on
insert into ABC_1 (column1, column2) select column1, column2 from ABC
set identity_insert ABC_1 off

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

Push Data

import android.content.Intent;

    ...

    Intent intent = 
        new Intent( 
            this, 
            MyActivity.class );
    intent.putExtra( "paramName", "paramValue" );
    startActivity( intent );

The above code might be inside the main activity. "MyActivity.class" is the second Activity we want to launch; it must be explicitly included in your AndroidManifest.xml file.

<activity android:name=".MyActivity" />

Pull Data

import android.os.Bundle;

    ...

    Bundle extras = getIntent().getExtras();
    if (extras != null)
    {
        String myParam = extras.getString("paramName");
    }
    else
    {
        //..oops!
    }

In this example, the above code would be inside your MyActivity.java file.

Gotchas

This method can only pass strings. So let's say you need to pass an ArrayList to your ListActivity; a possible workaround is to pass a comma-separated-string and then split it on the other side.

Alternative Solutions

Use SharedPreferences

Previous answers are good, I'd just like to share a utility function I wrote to select Tensors from a graph:

def get_graph_op(graph, and_conds=None, op='and', or_conds=None):
    """Selects nodes' names in the graph if:
    - The name contains all items in and_conds
    - OR/AND depending on op
    - The name contains any item in or_conds

    Condition starting with a "!" are negated.
    Returns all ops if no optional arguments is given.

    Args:
        graph (tf.Graph): The graph containing sought tensors
        and_conds (list(str)), optional): Defaults to None.
            "and" conditions
        op (str, optional): Defaults to 'and'. 
            How to link the and_conds and or_conds:
            with an 'and' or an 'or'
        or_conds (list(str), optional): Defaults to None.
            "or conditions"

    Returns:
        list(str): list of relevant tensor names
    """
    assert op in {'and', 'or'}

    if and_conds is None:
        and_conds = ['']
    if or_conds is None:
        or_conds = ['']

    node_names = [n.name for n in graph.as_graph_def().node]

    ands = {
        n for n in node_names
        if all(
            cond in n if '!' not in cond
            else cond[1:] not in n
            for cond in and_conds
        )}

    ors = {
        n for n in node_names
        if any(
            cond in n if '!' not in cond
            else cond[1:] not in n
            for cond in or_conds
        )}

    if op == 'and':
        return [
            n for n in node_names
            if n in ands.intersection(ors)
        ]
    elif op == 'or':
        return [
            n for n in node_names
            if n in ands.union(ors)
        ]

So if you have a graph with ops:

['model/classifier/dense/kernel',
'model/classifier/dense/kernel/Assign',
'model/classifier/dense/kernel/read',
'model/classifier/dense/bias',
'model/classifier/dense/bias/Assign',
'model/classifier/dense/bias/read',
'model/classifier/dense/MatMul',
'model/classifier/dense/BiasAdd',
'model/classifier/ArgMax/dimension',
'model/classifier/ArgMax']

Then running

get_graph_op(tf.get_default_graph(), ['dense', '!kernel'], 'or', ['Assign'])

returns:

['model/classifier/dense/kernel/Assign',
'model/classifier/dense/bias',
'model/classifier/dense/bias/Assign',
'model/classifier/dense/bias/read',
'model/classifier/dense/MatMul',
'model/classifier/dense/BiasAdd']

This is what finally worked for me:

DisplayMetrics metrics = this.getResources().getDisplayMetrics();
int width = metrics.widthPixels;
int height = metrics.heightPixels;

Different version similar to the one offered by Maxim Shoustin

I liked the answer but the part that bothered me was the use of <script id="..."> as a container for the modal's template.

I wanted to place the modal's template in a hidden <div> and bind the inner html with a scope variable called modal_html_template mainly because i think it more correct (and more comfortable to process in WebStorm/PyCharm) to place the template's html inside a <div> instead of <script id="...">

this variable will be used when calling $modal({... 'template': $scope.modal_html_template, ...})

in order to bind the inner html, i created inner-html-bind which is a simple directive

check out the example plunker

<div ng-controller="ModalDemoCtrl">

    <div inner-html-bind inner-html="modal_html_template" class="hidden">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
            <ul>
                <li ng-repeat="item in items">
                    <a ng-click="selected.item = item">{{ item }}</a>
                </li>
            </ul>
            Selected: <b>{{ selected.item }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </div>

    <button class="btn" ng-click="open()">Open me!</button>
    <div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>

inner-html-bind directive:

app.directive('innerHtmlBind', function() {
  return {
    restrict: 'A',
    scope: {
      inner_html: '=innerHtml'
    },
    link: function(scope, element, attrs) {
      scope.inner_html = element.html();
    }
  }
});

If you have been making commits on your main branch while you coded, but you now want to move those commits to a different branch, this is a quick way:

1. Copy your current history onto a new branch, bringing along any uncommitted changes too:

    git checkout -b <new-feature-branch>
   

2. Now force the original "messy" branch to roll back: (without switching to it)

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

   For example:

    git branch -f master origin/master
   

   or if you had made 4 commits:

    git branch -f master HEAD~4
   

Warning: git branch -f master origin/master will reset the tracking information for that branch. So if you have configured your master branch to push to somewhere other than origin/master then that configuration will be lost.

Warning: If you rebase after branching, there is a danger that some commits may be lost, which is described here. The only way to avoid that is to create a new history using cherry-pick. That link describes the safest fool-proof method, although less convenient. (If you have uncommitted changes, you may need to git stash at the start and git stash pop at the end.)

One difference is for r+ if the files does not exist, it'll not be created and open fails. But in case of a+ the file will be created if it does not exist.

If the case is accessing the IFrame via console, e. g. Chrome Dev Tools then you can just select the context of DOM requests via dropdown (see the picture).

To use in Eloquent. Add on top of your model

protected $table = 'table_name as alias'

//table_name should be exact as in your database

..then use in your query like

ModelName::query()->select(alias.id, alias.name)

You are catching the error but then you are re throwing it. You should try and handle it more gracefully, otherwise your user is going to see 500, internal server, errors.

You may want to send back a response telling the user what went wrong as well as logging the error on your server.

I am not sure exactly what errors the request might return, you may want to return something like.

router.get("/emailfetch", authCheck, async (req, res) => {
  try {
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
      emailFetch = emailFetch.data
      res.send(emailFetch)
   } catch(error) {
      res.status(error.response.status)
      return res.send(error.message);
    })

})

This code will need to be adapted to match the errors that you get from the axios call.

I have also converted the code to use the try and catch syntax since you are already using async.

>>> r = re.compile("([a-zA-Z]+)([0-9]+)")
>>> m = r.match("foobar12345")
>>> m.group(1)
'foobar'
>>> m.group(2)
'12345'

So, if you have a list of strings with that format:

import re
r = re.compile("([a-zA-Z]+)([0-9]+)")
strings = ['foofo21', 'bar432', 'foobar12345']
print [r.match(string).groups() for string in strings]

Output:

[('foofo', '21'), ('bar', '432'), ('foobar', '12345')]

You need add parameter errors='coerce' to function to_numeric:

ID = pd.to_numeric(ID, errors='coerce')

If ID is column:

df.ID = pd.to_numeric(df.ID, errors='coerce')

but non numeric are converted to NaN, so all values are float.

For int need convert NaN to some value e.g. 0 and then cast to int:

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)

Sample:

df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)
              ID
0  4806105017087
1  4806105017087
2       CN414149

print (pd.to_numeric(df.ID, errors='coerce'))
0    4.806105e+12
1    4.806105e+12
2             NaN
Name: ID, dtype: float64

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
print (df)
              ID
0  4806105017087
1  4806105017087
2              0

EDIT: If use pandas 0.25+ then is possible use integer_na:

df.ID = pd.to_numeric(df.ID, errors='coerce').astype('Int64')
print (df)
              ID
0  4806105017087
1  4806105017087
2            NaN

Don’t Repeat Your CSS

 a.abc, a.xyz{
    margin-left:20px;
 }

OR

 a{
    margin-left:20px;
 }

I use something like this function I created...

Object.getKeys = function(obj, add) {
    if(obj === undefined || obj === null) {
        return undefined;
    }
    var keys = [];
    if(add !== undefined) {
        keys = jQuery.merge(keys, add);
    }
    for(key in obj) {
        if(obj.hasOwnProperty(key)) {
                keys.push(key);
        }
    }
    return keys;
};

I think you could set obj to self or something better in the first test. It seems sometimes I'm checking if it's empty too so I did it that way. Also I don't think {} is Object.* or at least there's a problem finding the function getKeys on the Object that way. Maybe you're suppose to put prototype first, but that seems to cause a conflict with GreenSock etc.

If your VM already came with VMware Tools pre-installed, but this still isn't working for you--or if you install and still no luck--make sure you run Workstation or Player as Administrator. That fixed the issue for me.

You can get all keys in the Request.Form and then compare and get your desired values.

Your method body will look like this: -

List<int> listValues = new List<int>();
foreach (string key in Request.Form.AllKeys)
{
    if (key.StartsWith("List"))
    {
        listValues.Add(Convert.ToInt32(Request.Form[key]));
    }
}

You can use the -notmatch operator to get the lines that don't have the characters you are interested in.

     Get-Content $FileName | foreach-object { 
     if ($_ -notmatch $arrayofStringsNotInterestedIn) { $) }

Slightly faster version of the implementation (If you know that most couples lists will have different lengths):

def checkEqual(L1, L2):
    return len(L1) == len(L2) and sorted(L1) == sorted(L2)

Comparing:

>>> timeit(lambda: sorting([1,2,3], [3,2,1]))
2.42745304107666
>>> timeit(lambda: lensorting([1,2,3], [3,2,1]))
2.5644469261169434 # speed down not much (for large lists the difference tends to 0)

>>> timeit(lambda: sorting([1,2,3], [3,2,1,0]))
2.4570400714874268
>>> timeit(lambda: lensorting([1,2,3], [3,2,1,0]))
0.9596951007843018 # speed up

Pagination queries with ordering are really tricky in Oracle.

Oracle provides a ROWNUM pseudocolumn that returns a number indicating the order in which the database selects the row from a table or set of joined views.

ROWNUM is a pseudocolumn that gets many people into trouble. A ROWNUM value is not permanently assigned to a row (this is a common misunderstanding). It may be confusing when a ROWNUM value is actually assigned. A ROWNUM value is assigned to a row after it passes filter predicates of the query but before query aggregation or sorting.

What is more, a ROWNUM value is incremented only after it is assigned.

This is why the followin query returns no rows:

 select * 
 from (select *
       from some_table
       order by some_column)
 where ROWNUM <= 4 and ROWNUM > 1; 

The first row of the query result does not pass ROWNUM > 1 predicate, so ROWNUM does not increment to 2. For this reason, no ROWNUM value gets greater than 1, consequently, the query returns no rows.

Correctly defined query should look like this:

select *
from (select *, ROWNUM rnum
      from (select *
            from skijump_results
            order by points)
      where ROWNUM <= 4)
where rnum > 1;

If you want to link, say, libapplejuice statically, but not, say, liborangejuice, you can link like this:

gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary

There's a caveat -- if liborangejuice uses libapplejuice, then libapplejuice will be dynamically linked too.

You'll have to link liborangejuice statically alongside with libapplejuice to get libapplejuice static.

And don't forget to keep -Wl,-Bdynamic else you'll end up linking everything static, including libc (which isn't a good thing to do).

I think you are not asking the right question--

A string in python has no property corresponding to 'ascii', utf-8, or any other encoding. The source of your string (whether you read it from a file, input from a keyboard, etc.) may have encoded a unicode string in ascii to produce your string, but that's where you need to go for an answer.

Perhaps the question you can ask is: "Is this string the result of encoding a unicode string in ascii?" -- This you can answer by trying:

try:
    mystring.decode('ascii')
except UnicodeDecodeError:
    print "it was not a ascii-encoded unicode string"
else:
    print "It may have been an ascii-encoded unicode string"

I would suggest Jquery:

$("#log").html("Type what you want to be shown to the user");

There is no standard, so there is no guarantee. With that said, its common for the sitemap to be self labeled and on the root, like this:

example.com/sitemap.xml

Case is sensitive on some servers, so keep that in mind. If its not there, look in the robots file on the root:

example.com/robots.txt

If you don't see it listed in the robots file head to Google and search this:

site:example.com filetype:xml

This will limit the results to XML files on your target domain. At this point its trial-and-error and based on the specifics of the website you are working with. If you get several pages of results from the Google search phrase above then try to limit the results further:

filetype:xml site:example.com inurl:sitemap

You can do this with XSLT but I'm not sure about straight XPath.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" encoding="utf-8" indent="yes" 
              omit-xml-declaration="yes"/>
  <xsl:template match="a/*[text()='tsr']">
    <xsl:number value-of="position()"/>
  </xsl:template>
  <xsl:template match="text()"/>

Your idea to use enumerate() was correct.

indices = []
for i, elem in enumerate(mylist):
    if 'aa' in elem:
        indices.append(i)

Alternatively, as a list comprehension:

indices = [i for i, elem in enumerate(mylist) if 'aa' in elem]

You can iterate over a dictionary and grab an index with for-in and enumerate (like others have said, there is no guarantee it will come out ordered like below)

let dict = ["c": 123, "d": 045, "a": 456]

for (index, entry) in enumerate(dict) {
    println(index)   // 0       1        2
    println(entry)   // (d, 45) (c, 123) (a, 456)
}

If you want to sort first..

var sortedKeysArray = sorted(dict) { $0.0 < $1.0 }
println(sortedKeysArray)   // [(a, 456), (c, 123), (d, 45)]

var sortedValuesArray = sorted(dict) { $0.1 < $1.1 }
println(sortedValuesArray) // [(d, 45), (c, 123), (a, 456)]

then iterate.

for (index, entry) in enumerate(sortedKeysArray) {
    println(index)    // 0   1   2
    println(entry.0)  // a   c   d
    println(entry.1)  // 456 123 45
}

If you want to create an ordered dictionary, you should look into Generics.

This worked for me:

var message = new HttpRequestMessage(method, url);
message.Headers.TryAddWithoutValidation("user-agent", "<user agent header value>");
var client = new HttpClient();
var response = await client.SendAsync(message);

Here you can find the documentation for TryAddWithoutValidation

(function ($) {
  $.fn.inputFilter = function (inputFilter) {
    return this.on('input keydown keyup mousedown mouseup select contextmenu drop', function () {
      if (inputFilter(this.value)) {
        this.oldValue = this.value;
        this.oldSelectionStart = this.selectionStart;
        this.oldSelectionEnd = this.selectionEnd;
      } else if (this.hasOwnProperty('oldValue')) {
        this.value = this.oldValue;
        //this.setSelectionRange(this.oldSelectionStart, this.oldSelectionEnd);
      } else {
        this.value = '';
      }
    });
  };
})(jQuery);

$('.positive_int').inputFilter(function (value) {
  return /^\d*[.]?\d{0,2}$/.test(value);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="number" class="positive_int"/>

Above code works fine for all !!! And it will also prevent inserting more than 2 decimal points. And if you don't need this just remove\d{0,2} or if need more limited decimal point just change number 2

Just stumbled upon the same problem, I believe the final solution used by the author consisted in using a custom ContainerFactory:

public static Values parseJSONToMap(String msgData) {
    JSONParser parser = new JSONParser();
    ContainerFactory containerFactory = new ContainerFactory(){
        @Override
        public Map createObjectContainer() {
            return new LinkedHashMap();
        }

        @Override
        public List creatArrayContainer() {
            return null;
        }
    };
    try {
        return (Map<String,Object>)parser.parse(msgData, containerFactory);
    } catch (ParseException e) {
        log.warn("Exception parsing JSON string {}", msgData, e);
    }
    return null;
}  

see http://juliusdavies.ca/json-simple-1.1.1-javadocs/org/json/simple/parser/JSONParser.html#parse(java.io.Reader,org.json.simple.parser.ContainerFactory)

You need to use control characters as backslash (\b) and carriage return (\r). It come disabled by default, but the Console view can interpret these controls.

Windows>Preferences and Run/Debug > Console and select Interpret ASCII control characteres to enabled it

After these configurations, you can manage your console with control characters like:

\t - tab.

\b - backspace (a step backward in the text or deletion of a single character).

\n - new line.

\r - carriage return. ()

\f - form feed.

you can still use

String Item = getIntent().getExtras().getString("name");

in the fragment, you just need call getActivity() first:

String Item = getActivity().getIntent().getExtras().getString("name");

This saves you having to write some code.

If you are planing to use the same image for retina and non-retina screen then here is the solution. Say that you have a image of 200x200 and have two icons in top row and two icon in bottom row. So, it's four quadrants.

.sprite-of-icons {
  background: url("../images/icons-in-four-quad-of-200by200.png") no-repeat;
  background-size: 100px 100px /* Scale it down to 50% rather using 200x200 */
}

.sp-logo-1 { background-position: 0 0; }

/* Reduce positioning of the icons down to 50% rather using -50px */
.sp-logo-2 { background-position: -25px 0 }
.sp-logo-3 { background-position: 0 -25px }
.sp-logo-3 { background-position: -25px -25px }

Scaling and positioning of the sprite icons to 50% than actual value, you can get the expected result.

I hope I understand your question, but the ng-model directive creates a two-way binding between the selected item in the control and the value of item.selectedVariant. This means that changing item.selectedVariant in JavaScript, or changing the value in the control, updates the other. If item.selectedVariant has a value of 0, that item should get selected.

If variants is an array of objects, item.selectedVariant must be set to one of those objects. I do not know which information you have in your scope, but here's an example:

JS:

$scope.options = [{ name: "a", id: 1 }, { name: "b", id: 2 }];
$scope.selectedOption = $scope.options[1];

HTML:

<select data-ng-options="o.name for o in options" data-ng-model="selectedOption"></select>

This would leave the "b" item to be selected.

You could require the type to be a reference type :

 private static T ReadData<T>(XmlReader reader, string value) where T : class
 {
     reader.MoveToAttribute(value);
     object readData = reader.ReadContentAsObject();
     return (T)readData;
 }

And then do another that uses value types and TryParse...

 private static T ReadDataV<T>(XmlReader reader, string value) where T : struct
 {
     reader.MoveToAttribute(value);
     object readData = reader.ReadContentAsObject();
     int outInt;
     if(int.TryParse(readData, out outInt))
        return outInt
     //...
 }

Consider this:

std::string str = "Hello " + "world"; // bad!

Both the rhs and the lhs for operator + are char*s. There is no definition of operator + that takes two char*s (in fact, the language doesn't permit you to write one). As a result, on my compiler this produces a "cannot add two pointers" error (yours apparently phrases things in terms of arrays, but it's the same problem).

Now consider this:

std::string str = "Hello " + std::string("world"); // ok

There is a definition of operator + that takes a const char* as the lhs and a std::string as the rhs, so now everyone is happy.

You can extend this to as long a concatenation chain as you like. It can get messy, though. For example:

std::string str = "Hello " + "there " + std::string("world"); // no good!

This doesn't work because you are trying to + two char*s before the lhs has been converted to std::string. But this is fine:

std::string str = std::string("Hello ") + "there " + "world"; // ok

Because once you've converted to std::string, you can + as many additional char*s as you want.

If that's still confusing, it may help to add some brackets to highlight the associativity rules and then replace the variable names with their types:

((std::string("Hello ") + "there ") + "world");
((string + char*) + char*)

The first step is to call string operator+(string, char*), which is defined in the standard library. Replacing those two operands with their result gives:

((string) + char*)

Which is exactly what we just did, and which is still legal. But try the same thing with:

((char* + char*) + string)

And you're stuck, because the first operation tries to add two char*s.

Moral of the story: If you want to be sure a concatenation chain will work, just make sure one of the first two arguments is explicitly of type std::string.

I used Christian's Feb 12 solution and I'm also just beginning to learn PowerShell. As far as attachments, I was poking around with Get-Member learning how it works and noticed that Send() has two definitions... the second definition takes a System.Net.Mail.MailMessage object which allows for Attachments and many more powerful and useful features like Cc and Bcc. Here's an example that has attachments (to be mixed with his above example):

# append to Christian's code above --^
$emailMessage = New-Object System.Net.Mail.MailMessage
$emailMessage.From = $EmailFrom
$emailMessage.To.Add($EmailTo)
$emailMessage.Subject = $Subject
$emailMessage.Body = $Body
$emailMessage.Attachments.Add("C:\Test.txt")
$SMTPClient.Send($emailMessage)

If you're processing a large amount of data (many megabytes) then you want to be using XmlReader to stream parse the XML.

Anything else (XPathNavigator, XElement, XmlDocument and even XmlSerializer if you keep the full generated object graph) will result in high memory usage and also a very slow load time.

Of course, if you need all the data in memory anyway, then you may not have much choice.

In your case, because of the constraint you need to delete the duplicated records.

1. Find the duplicated rows
2. Organize them by created_at date - in this case I'm keeping the oldest
3. Delete the records with USING to filter the right rows

WITH duplicated AS ( 
    SELECT id,
        count(*) 
    FROM products 
    GROUP BY id 
    HAVING count(*) > 1), 
ordered AS ( 
    SELECT p.id, 
        created_at, 
        rank() OVER (partition BY p.id ORDER BY p.created_at) AS rnk 
    FROM products o 
    JOIN     duplicated d ON d.id = p.id ), 
products_to_delete AS ( 
    SELECT id, 
        created_at 
    FROM   ordered 
    WHERE  rnk = 2
) 
DELETE 
FROM products 
USING products_to_delete 
WHERE products.id = products_to_delete.id 
    AND products.created_at = products_to_delete.created_at;

Note (primarily, to potential downvoters). Presently, this may not be as efficient as other suggestions. Still, I leave it as an alternative, and a one, too, that can serve in seeing how faster other solutions are. (For you can't really tell fast from slow until you see the difference.) Also, as time goes on, changes could be made to MySQL's engine with regard to optimisation so as to make this solution, at some (perhaps, not so distant) point in future, to become quite comparable in efficiency with most others.

If you are using AWS Lambda with SprintBoot, then you must declare the following under environment variables:

key: JAVA_TOOL_OPTIONS & value: -Dspring.profiles.active=dev

From http://www.tech-recipes.com/rx/1475/save-mysql-query-results-into-a-text-or-csv-file/

SELECT order_id,product_name,qty
FROM orders
WHERE foo = 'bar'
INTO OUTFILE '/var/lib/mysql-files/orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';

Using this command columns names will not be exported.

Also note that /var/lib/mysql-files/orders.csv will be on the server that is running MySQL. The user that the MySQL process is running under must have permissions to write to the directory chosen, or the command will fail.

If you want to write output to your local machine from a remote server (especially a hosted or virtualize machine such as Heroku or Amazon RDS), this solution is not suitable.

Set a system variable named http_proxy with the value of ProxyServer:Port. That is the simplest solution. Respectively, use https_proxy as daefu pointed out in the comments.

Setting gitproxy (as sleske mentions) is another option, but that requires a "command", which is not as straightforward as the above solution.

References: http://bardofschool.blogspot.com/2008/11/use-git-behind-proxy.html

You might want to consider the difference between:

class A:
    def foo():  # no self parameter, no decorator
        pass

and

class B:
    @staticmethod
    def foo():  # no self parameter
        pass

This has changed between python2 and python3:

python2:

>>> A.foo()
TypeError
>>> A().foo()
TypeError
>>> B.foo()
>>> B().foo()

python3:

>>> A.foo()
>>> A().foo()
TypeError
>>> B.foo()
>>> B().foo()

So using @staticmethod for methods only called directly from the class has become optional in python3. If you want to call them from both class and instance, you still need to use the @staticmethod decorator.

The other cases have been well covered by unutbus answer.

If you are trying to access a server which is behind a NAT - you will most probably have to start your server with the option

-Djava.rmi.server.hostname=<public/NAT address>

so that the RMI stubs sent to the client contain the server's public address allowing it to be reached by the clients from the outside.

First, choosing a data structure(xml,json,yaml) usually includes only a readability/size problem. For example

Json is very compact, but no human being can read it easily, very hard do debug,

Xml is very large, but everyone can easily read/debug it,

Yaml is in between Xml and json.

But if you want to work with Javascript heavily and/or your software makes a lot of data transfer between browser-server, you should use Json, because it is pure javascript and very compact. But don't try to write it in a string, use libraries to generate the code you needed from an object.

Hope this helps.

It is terrible, but you can try to use

select
SUBSTRING(Table1.Col1,0,PATINDEX('%|%=',Table1.Col1)) as myString
from
Table1

This code is probably not 100% right though. need to be adjusted

If you still want a date instead of a string like the other answers, just add this extension method.

public static DateTime ToMillisecondPrecision(this DateTime d) {
    return new DateTime(d.Year, d.Month, d.Day, d.Hour, d.Minute,
                        d.Second, d.Millisecond, d.Kind);
}

There is a great library for it ts-json-object

In your case you would need to run the following code:

import {JSONObject, required} from 'ts-json-object'

class Response extends JSONObject {
    @required
    name: string;

    @required
    error: boolean;
}

let resp = new Response({"name": "Bob", "error": false});

This library will validate the json before parsing

I had a similar issue, but it didn't help to add extension=mysql.so in my php.ini. It turned out that the mysql.so file was not in my extension folder nor anywhere else on my machine. Solved this by downloading the php source and building the extension manually and then copying it into the extension folder.

As mentioned in the comments height:100% relies on the height of the parent container being explicitly defined. One way to achieve what you want is to use absolute/relative positioning, and specifying the left/right/top/bottom properties to "stretch" the content out to fill the available space. I have implemented what I gather you want to achieve in jsfiddle. Try resizing the Result window and you will see the content resizes automatically.

The limitation of this approach in your case is that you have to specify an explicit margin-top on the parent container to offset its contents down to make room for the header content. You can make it dynamic if you throw in javascript though.

You can use glob:

import glob, os
os.chdir("/mydir")
for file in glob.glob("*.txt"):
    print(file)

or simply os.listdir:

import os
for file in os.listdir("/mydir"):
    if file.endswith(".txt"):
        print(os.path.join("/mydir", file))

or if you want to traverse directory, use os.walk:

import os
for root, dirs, files in os.walk("/mydir"):
    for file in files:
        if file.endswith(".txt"):
             print(os.path.join(root, file))

Use GUID constructor standard functionality

Public Function IsValid(pString As String) As Boolean

    Try
        Dim mGuid As New Guid(pString)
    Catch ex As Exception
        Return False
    End Try
    Return True

End Function

eryksun has answered question #1, and I've answered question #3 (the original #4), but now let's answer question #2:

Why does it release 50.5mb in particular - what is the amount that is released based on?

What it's based on is, ultimately, a whole series of coincidences inside Python and malloc that are very hard to predict.

First, depending on how you're measuring memory, you may only be measuring pages actually mapped into memory. In that case, any time a page gets swapped out by the pager, memory will show up as "freed", even though it hasn't been freed.

Or you may be measuring in-use pages, which may or may not count allocated-but-never-touched pages (on systems that optimistically over-allocate, like linux), pages that are allocated but tagged MADV_FREE, etc.

If you really are measuring allocated pages (which is actually not a very useful thing to do, but it seems to be what you're asking about), and pages have really been deallocated, two circumstances in which this can happen: Either you've used brk or equivalent to shrink the data segment (very rare nowadays), or you've used munmap or similar to release a mapped segment. (There's also theoretically a minor variant to the latter, in that there are ways to release part of a mapped segment—e.g., steal it with MAP_FIXED for a MADV_FREE segment that you immediately unmap.)

But most programs don't directly allocate things out of memory pages; they use a malloc-style allocator. When you call free, the allocator can only release pages to the OS if you just happen to be freeing the last live object in a mapping (or in the last N pages of the data segment). There's no way your application can reasonably predict this, or even detect that it happened in advance.

CPython makes this even more complicated—it has a custom 2-level object allocator on top of a custom memory allocator on top of malloc. (See the source comments for a more detailed explanation.) And on top of that, even at the C API level, much less Python, you don't even directly control when the top-level objects are deallocated.

So, when you release an object, how do you know whether it's going to release memory to the OS? Well, first you have to know that you've released the last reference (including any internal references you didn't know about), allowing the GC to deallocate it. (Unlike other implementations, at least CPython will deallocate an object as soon as it's allowed to.) This usually deallocates at least two things at the next level down (e.g., for a string, you're releasing the PyString object, and the string buffer).

If you do deallocate an object, to know whether this causes the next level down to deallocate a block of object storage, you have to know the internal state of the object allocator, as well as how it's implemented. (It obviously can't happen unless you're deallocating the last thing in the block, and even then, it may not happen.)

If you do deallocate a block of object storage, to know whether this causes a free call, you have to know the internal state of the PyMem allocator, as well as how it's implemented. (Again, you have to be deallocating the last in-use block within a malloced region, and even then, it may not happen.)

If you do free a malloced region, to know whether this causes an munmap or equivalent (or brk), you have to know the internal state of the malloc, as well as how it's implemented. And this one, unlike the others, is highly platform-specific. (And again, you generally have to be deallocating the last in-use malloc within an mmap segment, and even then, it may not happen.)

So, if you want to understand why it happened to release exactly 50.5mb, you're going to have to trace it from the bottom up. Why did malloc unmap 50.5mb worth of pages when you did those one or more free calls (for probably a bit more than 50.5mb)? You'd have to read your platform's malloc, and then walk the various tables and lists to see its current state. (On some platforms, it may even make use of system-level information, which is pretty much impossible to capture without making a snapshot of the system to inspect offline, but luckily this isn't usually a problem.) And then you have to do the same thing at the 3 levels above that.

So, the only useful answer to the question is "Because."

Unless you're doing resource-limited (e.g., embedded) development, you have no reason to care about these details.

And if you are doing resource-limited development, knowing these details is useless; you pretty much have to do an end-run around all those levels and specifically mmap the memory you need at the application level (possibly with one simple, well-understood, application-specific zone allocator in between).

SLaks has the right answer... but let me be a bit more specific for people, like me, who are annoyed by this and can't find it right away :

Project -> Properties -> Application -> Target Framework -> select ".Net Framework 4"

the project will then save and reload.

The accepted answer didn't work in my situation, not sure why. I switched from JRE1.7 to JRE1.8 and that resolved the issue automatically. JRE1.8 uses TLS1.2 by default

Here is a plotrix solution:

set.seed(0815)
x <- 1:10
F <- runif(10,1,2) 
L <- runif(10,0,1)
U <- runif(10,2,3)

require(plotrix)
plotCI(x, F, ui=U, li=L)

And here is a ggplot solution:

set.seed(0815)
df <- data.frame(x =1:10,
                 F =runif(10,1,2),
                 L =runif(10,0,1),
                 U =runif(10,2,3))

require(ggplot2)
ggplot(df, aes(x = x, y = F)) +
  geom_point(size = 4) +
  geom_errorbar(aes(ymax = U, ymin = L))

UPDATE: Here is a base solution to your edits:

set.seed(1234)
x <- rnorm(20)
df <- data.frame(x = x,
                 y = x + rnorm(20))

plot(y ~ x, data = df)

# model
mod <- lm(y ~ x, data = df)

# predicts + interval
newx <- seq(min(df$x), max(df$x), length.out=100)
preds <- predict(mod, newdata = data.frame(x=newx), 
                 interval = 'confidence')

# plot
plot(y ~ x, data = df, type = 'n')
# add fill
polygon(c(rev(newx), newx), c(rev(preds[ ,3]), preds[ ,2]), col = 'grey80', border = NA)
# model
abline(mod)
# intervals
lines(newx, preds[ ,3], lty = 'dashed', col = 'red')
lines(newx, preds[ ,2], lty = 'dashed', col = 'red')

If you are trying to open a file in the same directory it would be:

./PROGRAM TRYING TO OPEN
./FILE NAME/PROGRAM TRYING TO OPEN (or this)

Or, if trying to backtrack from the same directory it would be:

../PROGRAM TRYING TO OPEN
../FILE NAME/PROGRAM TRYING TO OPEN (or this)

Else, if you need a straight one from start, it would be:

(DIRECTORY TYPE)\Users\%username%\(FILE DIRECTORY)
(ex) C:\Users\ajste\Desktop\Henlo.cmd

Simple copy & paste example with subqueries, Note, that both queries should return 1 row:

For .NET Core 2.2 you can publish the application and set the target to be a self-contained executable.

In Visual Studio right click your console application project. Select publish to folder and set the profile settings like so:

You'll find your compiled code with the .exe in the publish folder.

select t.data_type 
  from user_tab_columns t 
 where t.TABLE_NAME = 'xxx' 
   and t.COLUMN_NAME='aaa'

Since Java 1.5 we can use the method java.lang.String.format(String, Object...) and use printf like format.

The format string "%1$15s" do the job. Where 1$ indicates the argument index, s indicates that the argument is a String and 15 represents the minimal width of the String. Putting it all together: "%1$15s".

For a general method we have:

public static String fixedLengthString(String string, int length) {
    return String.format("%1$"+length+ "s", string);
}

Maybe someone can suggest another format string to fill the empty spaces with an specific character?

For the EditText if we specify,

android:inputType="number"

only numbers can be got. But if you use,

android:inputType="phone"

along with the numbers it can accept special characters like ;,/". etc.

We encountered similar errors in a testing environment on a virtual machine. If the machine name changes due to VM cloning from a template, you can get this error.

If the computer name changed from OLD to NEW.

A job uses this stored procedure:

msdb.dbo.sp_sqlagent_has_server_access @login_name = 'OLD\Administrator'

Which uses this one:

EXECUTE master.dbo.xp_logininfo 'OLD\Administrator'

Which gives this SQL error 15404

select text from sys.messages where message_id = 15404;
Could not obtain information about Windows NT group/user '%ls', error code %#lx.

Which I guess is correct, under the circumstances. We added a script to the VM cloning/deployment process that re-creates the SQL login.

As a summary

import sys
import re

f = sys.argv[1]
find = sys.argv[2]
replace = sys.argv[3]
with open (f, "r") as myfile:
     s=myfile.read()
ret = re.sub(find,replace, s)   # <<< This is where the magic happens
print ret

SqlPubWiz.exe (for me, it's in C:\Program Files (x86)\Microsoft SQL Server\90\Tools\Publishing\1.2>)

Run it with no arguments for a wizard. Give it arguments to run on commandline.

SqlPubWiz.exe script -C "<ConnectionString>" <OutputFile>

class Node {
    Object data;
    Node next;
    Node(Object d,Node n) {
        data = d ;
        next = n ;
       }

   public static Node addLast(Node header, Object x) {
       // save the reference to the header so we can return it.
       Node ret = header;

       // check base case, header is null.
       if (header == null) {
           return new Node(x, null);
       }

       // loop until we find the end of the list
       while ((header.next != null)) {
           header = header.next;
       }

       // set the new node to the Object x, next will be null.
       header.next = new Node(x, null);
       return ret;
   }
}

This should give you the current date minus 1 year:

anaconda prompt -->pip install opencv-python

Try this:

SELECT s.NAME + '.' + t.NAME AS TableName
FROM sys.tables t
INNER JOIN sys.schemas s
    ON t.schema_id = s.schema_id

it will display the schema+table name for all tables in the current database.

Here is a version that will list every table in every database on the current server. it allows a search parameter to be used on any part or parts of the server+database+schema+table names:

SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
DECLARE @Search nvarchar(4000)
       ,@SQL   nvarchar(4000)
SET @Search=null --all rows
SET @SQL='select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id WHERE @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name LIKE ''%'+ISNULL(@SEARCH,'')+'%'''

INSERT INTO @AllTables (CompleteTableName)
    EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1

set @Search to NULL for all tables, set it to things like 'dbo.users' or 'users' or '.master.dbo' or even include wildcards like '.master.%.u', etc.

You can alter a foreign key constraint with delete cascade option as shown below. This will delete chind table rows related to master table rows when deleted.

ALTER TABLE MasterTable
ADD CONSTRAINT fk_xyz 
FOREIGN KEY (xyz) 
REFERENCES ChildTable (xyz) ON DELETE CASCADE 

Since Java 7 this is very easy and intuitive to do.

List<String> fileContent = new ArrayList<>(Files.readAllLines(FILE_PATH, StandardCharsets.UTF_8));

for (int i = 0; i < fileContent.size(); i++) {
    if (fileContent.get(i).equals("old line")) {
        fileContent.set(i, "new line");
        break;
    }
}

Files.write(FILE_PATH, fileContent, StandardCharsets.UTF_8);

Basically you read the whole file to a List, edit the list and finally write the list back to file.

FILE_PATH represents the Path of the file.

You can use a lambda with an input parameter, like so:

.Returns((string myval) => { return myval; });

Or slightly more readable:

.Returns<string>(x => x);

As others have said you are "tainting" the canvas by loading from a cross origins domain.

https://developer.mozilla.org/en-US/docs/HTML/CORS_Enabled_Image

However, you may be able to prevent this by simply setting:

img.crossOrigin = "Anonymous";

This only works if the remote server sets the following header appropriately:

Access-Control-Allow-Origin "*"

The Dropbox file chooser when using the "direct link" option is a great example of this. I use it on oddprints.com to hoover up images from the remote dropbox image url, into my canvas, and then submit the image data back into my server. All in javascript

Try this one:

var data = [{id: 1, text: 'First'}, {id: 2, text: 'Second'}, {...}];
$('select[name="my_select"]').empty().select2({
    data: data
});

You can only access final variables from the containing class when using an anonymous class. Therefore you need to declare the variables being used final (which is not an option for you since you are changing lastPrice and price), or don't use an anonymous class.

So your options are to create an actual inner class, in which you can pass in the variables and use them in a normal fashion

or:

There is a quick (and in my opinion ugly) hack for your lastPrice and price variable which is to declare it like so

final double lastPrice[1];
final double price[1];

and in your anonymous class you can set the value like this

price[0] = priceObject.getNextPrice(lastPrice[0]);
System.out.println();
lastPrice[0] = price[0];

This query should work for you:

SELECT *
FROM table
WHERE MONTH(columnName) = MONTH(CURRENT_DATE())
AND YEAR(columnName) = YEAR(CURRENT_DATE())

I just tried the same and came up with following solution:

public enum Countries {
    TEXAS,
    FLORIDA,
    OKLAHOMA,
    KENTUCKY;

    private static Countries[] list = Countries.values();

    public static Countries getCountry(int i) {
        return list[i];
    }

    public static int listGetLastIndex() {
        return list.length - 1;
    }
}

The class has it's own values saved inside an array, and I use the array to get the enum at indexposition. As mentioned above arrays begin to count from 0, if you want your index to start from '1' simply change these two methods to:

public static String getCountry(int i) {
    return list[(i - 1)];
}

public static int listGetLastIndex() {
    return list.length;
}

Inside my Main I get the needed countries-object with

public static void main(String[] args) {
   int i = Countries.listGetLastIndex();
   Countries currCountry = Countries.getCountry(i);
}

which sets currCountry to the last country, in this case Countries.KENTUCKY.

Just remember this code is very affected by ArrayOutOfBoundsExceptions if you're using hardcoded indicies to get your objects.

BUILD_NUMBER is the current build number. You can use it in the command you execute for the job, or just use it in the script your job executes.

In my case, migrating a Spring 3.1 app up to 3.2.7, my solution was similar to Matthias's but a bit different -- thus why I'm documenting it here:

In my POM I found this dependency and changed it from 6.0 to 7.0:

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>7.0</version>
        <scope>provided</scope>
    </dependency>

Then later in the POM I upgraded this plugin from 6.0 to 7.0:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>
                    ...
                    <configuration>
                        ...
                        <artifactItems>
                            <artifactItem>
                                <groupId>javax</groupId>
                                <artifactId>javaee-endorsed-api</artifactId>
                                <version>7.0</version>
                                <type>jar</type>
                            </artifactItem>
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>

You need just to delete your older connector and download new version (mysql-connector-java-5.1.46)

Here is how do it with single statement

WITH deleted_rows AS (
DELETE FROM source_table WHERE id = 1
RETURNING *
) 
INSERT INTO destination_table 
SELECT * FROM deleted_rows;

EXAMPLE:

    postgres=# select * from test1 ;
 id |  name
----+--------
  1 | yogesh
  2 | Raunak
  3 | Varun
(3 rows)


postgres=# select * from test2;
 id | name
----+------
(0 rows)


postgres=# WITH deleted_rows AS (
postgres(# DELETE FROM test1 WHERE id = 1
postgres(# RETURNING *
postgres(# )
postgres-# INSERT INTO test2
postgres-# SELECT * FROM deleted_rows;
INSERT 0 1


postgres=# select * from test2;
 id |  name
----+--------
  1 | yogesh
(1 row)

postgres=# select * from test1;
 id |  name
----+--------
  2 | Raunak
  3 | Varun

Late answer (8 yrs), but for someone looking to join multiple files into one, the following function may be of help:

def multi_open(_list):
    out=""
    for x in _list:
        try:
            with open(x) as f:
                out+=f.read()
        except:
            pass
            # print(f"Cannot open file {x}")
    return(out)

fl = ["C:/bdlog.txt", "C:/Jts/tws.vmoptions", "C:/not.exist"]
print(multi_open(fl))

This is an reality example when customize folder structure: Folder structure, and initialize class HibernateUtil

with:

return new Configuration().configure("/config/hibernate.cfg.xml").buildSessionFactory();

mapping:

with customize entities mapping files:

        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <mapping class="com.vy.entities.Users"/>
        <mapping class="com.vy.entities.Post"/>
        <mapping resource="config/Users.hbm.xml"/>      
        <mapping resource="config/Post.hbm.xml"/>               
    </session-factory>
</hibernate-configuration>

(Note: Simplest way, if you follow default way, it means put all xml config files inside src folder, when build sessionFactory, only:

return new Configuration().configure().buildSessionFactory();

)

You use RAISE_APPLICATION_ERROR in order to create an Oracle style exception/error that is specific to your code/needs. Good use of these help to produce code that is clearer, more maintainable, and easier to debug.

For example, if I have an application calling a stored procedure that adds a user and that user already exists, you'll usually get back an error like:

ORA-00001: unique constraint (USERS.PK_USER_KEY) violated

Obviously this error and associated message are not unique to the task you were trying to do. Creating your own Oracle application errors allow you to be clearer on the intent of the action and the cause of the issue.

raise_application_error(-20101, 'User ' || in_user || ' already exists!');

Now your application code can write an exception handler in order to process this specific error condition. Think of it as a way to make Oracle communicate error conditions that your application expects in a "language" (for lack of a better term) that you have defined and is more meaningful to your application's problem domain.

Note that user defined errors must be in the range between -20000 and -20999.

The following link provides lots of good information on this topic and Oracle exceptions in general.

To access "Host Manager" you have to configure "admin-gui" user inside the tomcat-users.xml

Just add the below lines[change username & pwd] :

<role rolename="admin-gui"/>
<user username="admin" password="password" roles="admin-gui"/>

Restart tomcat 7 server and you are done.

It seems like the visibility problem - the parent controller doesn't see the Component you are trying to wire.

Try to add

@ComponentScan("path to respective Component") 

to the parent controller.

The default behaviour is false:

By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup.

I suggest reading up

If anyone cares I found this post initially, but I use ASP.NET's build in Validation on the page. The solutions work, but disable the button even if its been validated. You can use this following code in order to make it so it only disables the button if it passes page validation.

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Submit" OnClientClick=" if ( Page_ClientValidate() ) { this.value='Submitting..'; this.disabled=true; }" UseSubmitBehavior="false" />

The .pde file extension is the one used by the Processing, Wiring, and the Arduino IDE.

Processing is not C-based but rather Java-based and with a syntax derived from Java. It is a Java framework that can be used as a Java library. It includes a default IDE that uses .pde extension. Just wanted to rectify @kersny's answer.

Wiring is a microcontroller that uses the same IDE. Arduino uses a modified version, but also with .pde. The OpenProcessing page where you found it is a website to exhibit some Processing work.

If you know Java, it should be fairly easy to convert the Processing code to Java AWT.

• This code compiles and runs smoothly.
• It uses no iterator so more readable.
• list is your collection.
• result is filtered form (no null no empty).

public static void listRemove() {
    List<String> list = Arrays.asList("", "Hi", "", "How", "are", "you");
    List<String> result = new ArrayList<String>();

    for (String str : list) {
        if (str != null && !str.isEmpty()) {
            result.add(str);
        }
    }

    System.out.println(result);
}

Is Button1 visible? I mean, from the server side. Make sure Button1.Visible is true.

Controls that aren't Visible won't be rendered in HTML, so although they are assigned a ClientID, they don't actually exist on the client side.

EDIT : this answer used to claim that it isn't possible to center an absolutely positioned element with margin: auto;, but this simply isn't true. Because this is the most up-voted and accepted answer, I guessed I'd just change it to be correct.

When you apply the following CSS to an element

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;

And then give the element a fixed width and height, such as 200px or 40%, the element will center itself.

Here's a Fiddle that demonstrates the effect.

If you are a mac user this worked for me:

1. open Keychain Access.
2. Search for Bitbucket accounts.
3. Delete them.

Then it will ask you for the password again.

I could not made your code to do the desired query, the AS is an alias only for the table abc, not for the derived table. Laravel Query Builder does not implicitly support derived table aliases, DB::raw is most likely needed for this.

The most straight solution I could came up with is almost identical to yours, however produces the query as you asked for:

$sql = Abc::groupBy('col1')->toSql();
$count = DB::table(DB::raw("($sql) AS a"))->count();

The produced query is

select count(*) as aggregate from (select * from `abc` group by `col1`) AS a;

How about PlantUML? It's not for reverse engineering!!! It's for engineering before you code.

You are doing Integer division, so you will lose the correct length if the user happens to put in an odd number of inputs - that is one problem I noticed. Because of this, when I run the code with an input of '1,2,3,4,5,6,7' my last value is ignored...

Here, the '\n' left by cin, is creating issues.

do {
    system("cls");
    manageCustomerMenu();
    cin >> choice;               #This cin is leaving a trailing \n
    system("cls");

    switch (choice) {
        case '1':
            createNewCustomer();
            break;

This \n is being consumed by next getline in createNewCustomer(). You should use getline instead -

do {
    system("cls");
    manageCustomerMenu();
    getline(cin, choice)               
    system("cls");

    switch (choice) {
        case '1':
            createNewCustomer();
            break;

I think this would resolve the issue.

There should be

$('.send_upload')

but not $('.upload')

Similar to unutbu's answer, you can use numpy's arange function, which is analog to Python's intrinsic function range. Notice that the end point is not included, as in range:

>>> import numpy as np
>>> a = np.arange(0,5, 0.5)
>>> a
array([ 0. ,  0.5,  1. ,  1.5,  2. ,  2.5,  3. ,  3.5,  4. ,  4.5])
>>> a = np.arange(0,5, 0.5) # returns a numpy array
>>> a
array([ 0. ,  0.5,  1. ,  1.5,  2. ,  2.5,  3. ,  3.5,  4. ,  4.5])
>>> a.tolist() # if you prefer it as a list
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5]

I would suggest the use of exists instead of in because in some scenarios that implies null values the behavior is different, so

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    DELETE FROM database2.dbo.table2 childTable
    WHERE bar = 4 AND exists (SELECT id FROM deleted where deleted.id = childTable.id)
GO

<p>
    @Html.ActionLink("Create New", "Create")
</p>
@using (Html.BeginForm("Index", "Company", FormMethod.Get))
{
    <p>
        Find by Name: @Html.TextBox("SearchString", ViewBag.CurrentFilter as string)
        <input type="submit" value="Search" />
        <input type="button" value="Clear" onclick="location.href='@Url.Action("Index","Company")'"/>
    </p>
}

In the above example you can see that If I specifically need a button to do some action, I have to do it with @Url.Action whereas if I just want a link I will use @Html.ActionLink. The point is when you have to use some element(HTML) with action url is used.

            <li class="place-right" data-ng-if="!topMenuData.showSmall" data-ng-click="toggleFullScreen()">Full Screen</li>
            <li class="place-right" data-ng-if="topMenuData.showSmall" data-ng-click="toggleFullScreen()">Back</li>
        </ul>

Add Validate Connection=true to your connection string.

Look at this blog to find more about.

DETAILS: After OracleConnection.Close() the real database connection does not terminate. The connection object is put back in connection pool. The use of connection pool is implicit by ODP.NET. If you create a new connection you get one of the pool. If this connection is "yet open" the OracleConnection.Open() method does not really creates a new connection. If the real connection is broken (for any reason) you get a failure on first select, update, insert or delete.

With Validate Connection the real connection is validated in Open() method.

Ben Nadel has written a good article about this, he points out the difference in the parameters to these functions:

String.slice( begin [, end ] )
String.substring( from [, to ] )
String.substr( start [, length ] )

He also points out that if the parameters to slice are negative, they reference the string from the end. Substring and substr doesn't.

Here is his article about this.

If I check with Count() Linq executes a "SELECT COUNT(*).." in the database, but I need to check if the results contains data, I resolved to introducing FirstOrDefault() instead of Count();

Before

var cfop = from tabelaCFOPs in ERPDAOManager.GetTable<TabelaCFOPs>()

if (cfop.Count() > 0)
{
    var itemCfop = cfop.First();
    //....
}

After

var cfop = from tabelaCFOPs in ERPDAOManager.GetTable<TabelaCFOPs>()

var itemCfop = cfop.FirstOrDefault();

if (itemCfop != null)
{
    //....
}

You can still use installutil without visual studio, it is included with the .net framework

On your server, open a command prompt as administrator then:

CD C:\Windows\Microsoft.NET\Framework\v4.0.version (insert your version)

installutil "C:\Program Files\YourWindowsService\YourWindowsService.exe" (insert your service name/location)

To uninstall:

installutil /u "C:\Program Files\YourWindowsService\YourWindowsService.exe" (insert your service name/location)

an easiest way which i used and worked well

date('Y-m-d', strtotime('-1 year'));

this worked perfect.. hope this will help someone else too.. :)

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

A cookie is just another HTTP header. You can always set it while making a HTTP call with the apache library or with HTTPUrlConnection. Either way you should be able to read and set HTTP cookies in this fashion.

You can read this article for more information.

I can share my peace of code to demonstrate how easy you can make it.

public static String getServerResponseByHttpGet(String url, String token) {

        try {
            HttpClient client = new DefaultHttpClient();
            HttpGet get = new HttpGet(url);
            get.setHeader("Cookie", "PHPSESSID=" + token + ";");
            Log.d(TAG, "Try to open => " + url);

            HttpResponse httpResponse = client.execute(get);
            int connectionStatusCode = httpResponse.getStatusLine().getStatusCode();
            Log.d(TAG, "Connection code: " + connectionStatusCode + " for request: " + url);

            HttpEntity entity = httpResponse.getEntity();
            String serverResponse = EntityUtils.toString(entity);
            Log.d(TAG, "Server response for request " + url + " => " + serverResponse);

            if(!isStatusOk(connectionStatusCode))
                return null;

            return serverResponse;

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

This Regex let you avoid wrong result with digits which consits only from zeroes "0000" and work on digits of any length:

using System.Text.RegularExpressions;

/*
00123 => 123
00000 => 0
00000a => 0a
00001a => 1a
00001a => 1a
0000132423423424565443546546356546454654633333a => 132423423424565443546546356546454654633333a
*/

Regex removeLeadingZeroesReg = new Regex(@"^0+(?=\d)");
var strs = new string[]
{
    "00123",
    "00000",
    "00000a",
    "00001a",
    "00001a",
    "0000132423423424565443546546356546454654633333a",
};
foreach (string str in strs)
{
    Debug.Print(string.Format("{0} => {1}", str, removeLeadingZeroesReg.Replace(str, "")));
}

And this regex will remove leading zeroes anywhere inside string:

new Regex(@"(?<!\d)0+(?=\d)");
//  "0000123432 d=0 p=002 3?0574 m=600"
//     => "123432 d=0 p=2 3?574 m=600"

this seems to work fine :

dataframe.axes[0].tolist()

While Docker for Windows is perfectly able to run Linux containers, the converse, while theoretically possible, is not implemented due to practical reasons.

The most obvious one is, while Docker for Windows can run a Linux VM freely, Docker for Linux would require a Windows license in order to run it inside a VM.

Also, Linux is completely customizable, so the Linux VM used by Docker for Windows has been stripped down to just a few MB, containing only the bare minimum needed to run the containers, while the smallest Windows distribution available is about 1.5 GB. It may not be an impracticable size, but it is much more cumbersome than the Linux on Windows counterpart.

While it is certainly possible for someone to sell a Docker for Linux variation bundled with a Windows license and ready to run Windows containers under Linux (and I don't know if such product exists), the bottom line is that you can't avoid paying Windows vendor lock-in price: both in money and storage space.

In C# you cannot define true global variables (in the sense that they don't belong to any class).

This being said, the simplest approach that I know to mimic this feature consists in using a static class, as follows:

public static class Globals
{
    public const Int32 BUFFER_SIZE = 512; // Unmodifiable
    public static String FILE_NAME = "Output.txt"; // Modifiable
    public static readonly String CODE_PREFIX = "US-"; // Unmodifiable
}

You can then retrieve the defined values anywhere in your code (provided it's part of the same namespace):

String code = Globals.CODE_PREFIX + value.ToString();

In order to deal with different namespaces, you can either:

• declare the Globals class without including it into a specific namespace (so that it will be placed in the global application namespace);
• insert the proper using directive for retrieving the variables from another namespace.

In addition to what has been said, prior to returning your error code, fire off an assert or similar diagnostic when an error is returned, as it will make tracing a lot easier. The way I do this is to have a customised assert that still gets compiled in at release but only gets fired when the software is in diagnostics mode, with an option to silently report to a log file or pause on screen.

I personally return error codes as negative integers with no_error as zero , but it does leave you with the possible following bug

if (MyFunc())
 DoSomething();

An alternative is have a failure always returned as zero, and use a LastError() function to provide details of the actual error.

PKCS#1 OAEP is an asymmetric cipher based on RSA and the OAEP padding

from Crypto.PublicKey import RSA
from Crypto import Random
from Crypto.Cipher import PKCS1_OAEP


def rsa_encrypt_decrypt():
    key = RSA.generate(2048)
    private_key = key.export_key('PEM')
    public_key = key.publickey().exportKey('PEM')
    message = input('plain text for RSA encryption and decryption:')
    message = str.encode(message)

    rsa_public_key = RSA.importKey(public_key)
    rsa_public_key = PKCS1_OAEP.new(rsa_public_key)
    encrypted_text = rsa_public_key.encrypt(message)
    #encrypted_text = b64encode(encrypted_text)

    print('your encrypted_text is : {}'.format(encrypted_text))


    rsa_private_key = RSA.importKey(private_key)
    rsa_private_key = PKCS1_OAEP.new(rsa_private_key)
    decrypted_text = rsa_private_key.decrypt(encrypted_text)

    print('your decrypted_text is : {}'.format(decrypted_text))

The message error means that you have a self referencing loop.

The json you produce is like this example (with a list of one employee) :

[
employee1 : {
    name: "name",
    department : {
        name: "departmentName",
        employees : [
            employee1 : {
                name: "name",
                department : {
                    name: "departmentName",
                    employees : [
                        employee1 : {
                            name: "name",
                            department : {
                                and again and again....
                            }
                    ]
                }
            }
        ]
    }
}

]

You have to tell the db context that you don't want to get all linked entities when you request something. The option for DbContext is Configuration.LazyLoadingEnabled

The best way I found is to create a context for serialization :

public class SerializerContext : LabEntities 
{
    public SerializerContext()
    {
        this.Configuration.LazyLoadingEnabled = false;
    }
}

Here's an example that puts the Now() value in column A.

Sub move()
    Dim i As Integer
    Dim sh1 As Worksheet
    Dim sh2 As Worksheet
    Dim nextRow As Long
    Dim copyRange As Range
    Dim destRange As Range

    Application.ScreenUpdating = False

        Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
        Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
        Set copyRange = sh1.Range("A1:A5")

        i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4

        Set destRange = sh2.Range("B" & i)

        destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
        destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")

        copyRange.Clear

    Application.ScreenUpdating = True

End Sub

There are better ways of getting the last row in column B than using a While loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3 have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)

I just used a snippet of jquery to solve this problem.

$("input[data-val-length-max]").each(function (index, element) {
   var length = parseInt($(this).attr("data-val-length-max"));
   $(this).prop("maxlength", length);
});

The selector finds all of the elements that have a data-val-length-max attribute set. This is the attribute that the StringLength validation attribute will set.

The each loop loops through these matches and will parse out the value for this attribute and assign it to the mxlength property that should have been set.

Just add this to you document ready function and you are good to go.

An rvalue reference is a type that behaves much like the ordinary reference X&, with several exceptions. The most important one is that when it comes to function overload resolution, lvalues prefer old-style lvalue references, whereas rvalues prefer the new rvalue references:

void foo(X& x);  // lvalue reference overload
void foo(X&& x); // rvalue reference overload

X x;
X foobar();

foo(x);        // argument is lvalue: calls foo(X&)
foo(foobar()); // argument is rvalue: calls foo(X&&)

So what is an rvalue? Anything that is not an lvalue. An lvalue being an expression that refers to a memory location and allows us to take the address of that memory location via the & operator.

It is almost easier to understand first what rvalues accomplish with an example:

 #include <cstring>
 class Sample {
  int *ptr; // large block of memory
  int size;
 public:
  Sample(int sz=0) : ptr{sz != 0 ? new int[sz] : nullptr}, size{sz} 
  {
     if (ptr != nullptr) memset(ptr, 0, sz);
  }
  // copy constructor that takes lvalue 
  Sample(const Sample& s) : ptr{s.size != 0 ? new int[s.size] :\
      nullptr}, size{s.size}
  {
     if (ptr != nullptr) memcpy(ptr, s.ptr, s.size);
     std::cout << "copy constructor called on lvalue\n";
  }

  // move constructor that take rvalue
  Sample(Sample&& s) 
  {  // steal s's resources
     ptr = s.ptr;
     size = s.size;        
     s.ptr = nullptr; // destructive write
     s.size = 0;
     cout << "Move constructor called on rvalue." << std::endl;
  }    
  // normal copy assignment operator taking lvalue
  Sample& operator=(const Sample& s)
  {
   if(this != &s) {
      delete [] ptr; // free current pointer
      size = s.size;

      if (size != 0) {
        ptr = new int[s.size];
        memcpy(ptr, s.ptr, s.size);
      } else 
         ptr = nullptr;
     }
     cout << "Copy Assignment called on lvalue." << std::endl;
     return *this;
  }    
 // overloaded move assignment operator taking rvalue
 Sample& operator=(Sample&& lhs)
 {
   if(this != &s) {
      delete [] ptr; //don't let ptr be orphaned 
      ptr = lhs.ptr;   //but now "steal" lhs, don't clone it.
      size = lhs.size; 
      lhs.ptr = nullptr; // lhs's new "stolen" state
      lhs.size = 0;
   }
   cout << "Move Assignment called on rvalue" << std::endl;
   return *this;
 }
//...snip
};     

The constructor and assignment operators have been overloaded with versions that take rvalue references. Rvalue references allow a function to branch at compile time (via overload resolution) on the condition "Am I being called on an lvalue or an rvalue?". This allowed us to create more efficient constructor and assignment operators above that move resources rather copy them.

The compiler automatically branches at compile time (depending on the whether it is being invoked for an lvalue or an rvalue) choosing whether the move constructor or move assignment operator should be called.

Summing up: rvalue references allow move semantics (and perfect forwarding, discussed in the article link below).

One practical easy-to-understand example is the class template std::unique_ptr. Since a unique_ptr maintains exclusive ownership of its underlying raw pointer, unique_ptr's can't be copied. That would violate their invariant of exclusive ownership. So they do not have copy constructors. But they do have move constructors:

template<class T> class unique_ptr {
  //...snip
 unique_ptr(unique_ptr&& __u) noexcept; // move constructor
};

 std::unique_ptr<int[] pt1{new int[10]};  
 std::unique_ptr<int[]> ptr2{ptr1};// compile error: no copy ctor.  

 // So we must first cast ptr1 to an rvalue 
 std::unique_ptr<int[]> ptr2{std::move(ptr1)};  

std::unique_ptr<int[]> TakeOwnershipAndAlter(std::unique_ptr<int[]> param,\
 int size)      
{
  for (auto i = 0; i < size; ++i) {
     param[i] += 10;
  }
  return param; // implicitly calls unique_ptr(unique_ptr&&)
}

// Now use function     
unique_ptr<int[]> ptr{new int[10]};

// first cast ptr from lvalue to rvalue
unique_ptr<int[]> new_owner = TakeOwnershipAndAlter(\
           static_cast<unique_ptr<int[]>&&>(ptr), 10);

cout << "output:\n";

for(auto i = 0; i< 10; ++i) {
   cout << new_owner[i] << ", ";
}

output:
10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 

static_cast<unique_ptr<int[]>&&>(ptr) is usually done using std::move

// first cast ptr from lvalue to rvalue
unique_ptr<int[]> new_owner = TakeOwnershipAndAlter(std::move(ptr),0);

An excellent article explaining all this and more (like how rvalues allow perfect forwarding and what that means) with lots of good examples is Thomas Becker's C++ Rvalue References Explained. This post relied heavily on his article.

A shorter introduction is A Brief Introduction to Rvalue References by Stroutrup, et. al

xyz.setColumns() method is control the width of TextField.

import java.awt.*;
import javax.swing.*;



class miniproj extends JFrame {

  public static void main(String[] args)
  {
    JFrame frame=new JFrame();
    JPanel panel=new JPanel();
    frame.setSize(400,400);
    frame.setTitle("Registration");


    JLabel lablename=new JLabel("Enter your name");
    TextField tname=new TextField(30);
    tname.setColumns(45);

    JLabel lableemail=new JLabel("Enter your Email");
    TextField email=new TextField(30);
    email.setColumns(45);
    JLabel lableaddress=new JLabel("Enter your address");
    TextField address=new TextField(30);
    address.setColumns(45);
    address.setFont(Font.getFont(Font.SERIF));
    JLabel lablepass=new JLabel("Enter your password");
    TextField pass=new TextField(30);
    pass.setColumns(45);

    JButton login=new JButton();

This worked for me

class _SplashScreenState extends State<SplashScreen> {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: FittedBox(
        child: Image.asset("images/my_image.png"),
        fit: BoxFit.fill,
      ),);
  }
}

I tried to use dplyr::rename and I get an error:

occ_5d <- dplyr::rename(occ_5d, rowname='code_5d')
Error: Unknown column `code_5d` 
Call `rlang::last_error()` to see a backtrace

I instead used the base R function which turns out to be quite simple and effective:

names(occ_5d)[1] = "code_5d"

you can use the following to get all the lines in the file

$handle = @fopen('test.txt', "r");

if ($handle) { 
   while (!feof($handle)) { 
       $lines[] = fgets($handle, 4096); 
   } 
   fclose($handle); 
} 


print_r($lines);

and $lines[1] for your second line

This is the correct answer you can call onResume() providing the fragment is attached to the activity. Alternatively you can use onAttach and onDetach

You need

$('body').click(function(e) {
    if (!$(e.target).closest('.popup').length){
        $(".popup").hide();
    }
});

On linux I cannot set lower_case_table_names to 2 (it reverts to 0), but I can set it to 1.

Before changing this setting, do a complete dump of all databases, and drop all databases. You won't be able to drop them after setting lower_case_table_names to 1, because any uppercase characters in database or table names will prevent them from being referenced.

Then set lower_case_table_names to 1, restart MySQL, and re-load your data, which will convert everything to lowercase, including any subsequent queries made.

I have cuDNN 8.0 and none of the suggestions above worked for me. The desired information was in /usr/include/cudnn_version.h, so

cat /usr/include/cudnn_version.h | grep CUDNN_MAJOR -A 2

did the trick.

And incase you a different delimiter other than comma, you can use that as well.

@Value("#{'${my.config.values}'.split(',')}")
private String[] myValues;   // could also be a List<String>

and

in your application properties you could have

my.config.values=value1, value2, value3

You can also use file_put_contents():

file_put_contents('ids.txt', implode("\n", $gemList) . "\n", FILE_APPEND);

You can use ElementRef as shown below,

DEMO : https://plnkr.co/edit/XZwXEh9PZEEVJpe0BlYq?p=preview check browser's console.

import { Directive,Input,Outpu,ElementRef,Renderer} from '@angular/core';

@Directive({
  selector:"[move]",
  host:{
    '(click)':"show()"
  }
})

export class GetEleDirective{

  constructor(private el:ElementRef){

  }
  show(){
    console.log(this.el.nativeElement);

    console.log('height---' + this.el.nativeElement.offsetHeight);  //<<<===here
    console.log('width---' + this.el.nativeElement.offsetWidth);    //<<<===here
  }
}

Same way you can use it within component itself wherever you need it.

You can use this snippet :-D

using System;
using System.Reflection;

public static class EnumUtils
{
    public static T GetDefaultValue<T>()
        where T : struct, Enum
    {
        return (T)GetDefaultValue(typeof(T));
    }

    public static object GetDefaultValue(Type enumType)
    {
        var attribute = enumType.GetCustomAttribute<DefaultValueAttribute>(inherit: false);
        if (attribute != null)
            return attribute.Value;

        var innerType = enumType.GetEnumUnderlyingType();
        var zero = Activator.CreateInstance(innerType);
        if (enumType.IsEnumDefined(zero))
            return zero;

        var values = enumType.GetEnumValues();
        return values.GetValue(0);
    }
}

Example:

using System;

public enum Enum1
{
    Foo,
    Bar,
    Baz,
    Quux
}
public enum Enum2
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 0
}
public enum Enum3
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4

    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}

public static class Program

    public static void Main() 
    {
        var defaultValue1 = EnumUtils.GetDefaultValue<Enum1>();
        Console.WriteLine(defaultValue1); // Foo

        var defaultValue2 = EnumUtils.GetDefaultValue<Enum2>();
        Console.WriteLine(defaultValue2); // Quux

        var defaultValue3 = EnumUtils.GetDefaultValue<Enum3>();
        Console.WriteLine(defaultValue3); // Foo

        var defaultValue4 = EnumUtils.GetDefaultValue<Enum4>();
        Console.WriteLine(defaultValue4); // Bar
    }
}

You may want to use the jasypt library (Java Simplified Encryption), which is quite easy to use. ( Also, it's recommended to check against the encrypted password rather than decrypting the encrypted password )

To use jasypt, if you're using maven, you can include jasypt into your pom.xml file as follows:

<dependency>
    <groupId>org.jasypt</groupId>
    <artifactId>jasypt</artifactId>
    <version>1.9.3</version>
    <scope>compile</scope>
</dependency>

And then to encrypt the password, you can use StrongPasswordEncryptor

public static String encryptPassword(String inputPassword) {
    StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
    return encryptor.encryptPassword(inputPassword);
}

Note: the encrypted password is different every time you call encryptPassword but the checkPassword method can still check that the unencrypted password still matches each of the encrypted passwords.

And to check the unencrypted password against the encrypted password, you can use the checkPassword method:

public static boolean checkPassword(String inputPassword, String encryptedStoredPassword) {
    StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
    return encryptor.checkPassword(inputPassword, encryptedStoredPassword);
}

The page below provides detailed information on the complexities involved in creating safe encrypted passwords.

http://www.jasypt.org/howtoencryptuserpasswords.html

In some cases this is the best way because your code may have change something and j=i+1 won't check that.

for (int i = 0; i < list.size(); i++){  
    for (int j = 0; j < list.size(); j++) {
                if(i == j) {
               //to do code here
                    continue;
                }

}

}

ES6 syntax

const captilizeAllWords = (sentence) => {
  if (typeof sentence !== "string") return sentence;
  return sentence.split(' ')
    .map(word => word.charAt(0).toUpperCase() + word.slice(1))
    .join(' ');
}


captilizeAllWords('Something is going on here')

From the man read:

#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);

Input parameters:

• int fd file descriptor is an integer and not a file pointer. The file descriptor for stdin is 0

• void *buf pointer to buffer to store characters read by the read function

• size_t count maximum number of characters to read

So you can read character by character with the following code:

char buf[1];

while(read(0, buf, sizeof(buf))>0) {
   // read() here read from stdin charachter by character
   // the buf[0] contains the character got by read()
   ....
}

My version of removing leading chars, one or multiple. For example, String str1 = "01234", when removing leading '0', result will be "1234". For a String str2 = "000123" result will be again "123". And for String str3 = "000" result will be empty string: "". Such functionality is often useful when converting numeric strings into numbers.The advantage of this solution compared with regex (replaceAll(...)) is that this one is much faster. This is important when processing large number of Strings.

 public static String removeLeadingChar(String str, char ch) {
    int idx = 0;
    while ((idx < str.length()) && (str.charAt(idx) == ch))
        idx++;
    return str.substring(idx);
}

Your printf needs a format string:

printf("%d\n", x);

This reference page gives details on how to use printf and related functions.

It could be an accounting issue. The Github account of the upstream (private) repo owner may not be financial. I've seen this where the client's credit card expired.

HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.

More details here.

You can try/catch PDOExceptions (your configs could differ but the important part is the try/catch):

try {
        $dbh = new PDO(
            DB_TYPE . ':host=' . DB_HOST . ';dbname=' . DB_NAME . ';charset=' . DB_CHARSET,
            DB_USER,
            DB_PASS,
            [
                PDO::ATTR_PERSISTENT            => true,
                PDO::ATTR_ERRMODE               => PDO::ERRMODE_EXCEPTION,
                PDO::MYSQL_ATTR_INIT_COMMAND    => 'SET NAMES ' . DB_CHARSET . ' COLLATE ' . DB_COLLATE

            ]
        );
    } catch ( PDOException $e ) {
        echo 'ERROR!';
        print_r( $e );
    }

The print_r( $e ); line will show you everything you need, for example I had a recent case where the error message was like unknown database 'my_db'.

Hi based on this comments ... i create a bash to export a list of URL from file URLS.txt to a URLS_DECODED.txt an used in some accelerator like flashget ( i use cygwin to combine windows & linux )

Command spider was introduced to avoid download and get the final link ( directly )

Command GREP HEAD and CUT, process and get the final link, Is based in spanish language, maybe you could be port to ENGLISH LANGUAGE

echo -e "$URL_TO_DOWNLOAD\r" probably the \r is only cywin and must be replace by a \n (break line)

**********user*********** is the user folder

*******Localización*********** is in spanish language, clear the asterics and let the word in english Location and adapt THE HEAD and the CUT numbers to appropiate approach.

rm -rf /home/**********user***********/URLS_DECODED.txt

    string=$p
    hash="${string#*id=}"
    hash="${hash%&*}"

Check out the open source library PureLayout. It offers a few API methods for distributing views, including variants where the spacing between each view is fixed (view size varies as needed), and where the size of each view is fixed (spacing between views varies as needed). Note that all of these are accomplished without the use of any "spacer views".

From NSArray+PureLayout.h:

// NSArray+PureLayout.h

// ...

/** Distributes the views in this array equally along the selected axis in their superview. Views will be the same size (variable) in the dimension along the axis and will have spacing (fixed) between them. */
- (NSArray *)autoDistributeViewsAlongAxis:(ALAxis)axis
                                alignedTo:(ALAttribute)alignment
                         withFixedSpacing:(CGFloat)spacing;

/** Distributes the views in this array equally along the selected axis in their superview. Views will be the same size (fixed) in the dimension along the axis and will have spacing (variable) between them. */
- (NSArray *)autoDistributeViewsAlongAxis:(ALAxis)axis
                                alignedTo:(ALAttribute)alignment
                            withFixedSize:(CGFloat)size;

// ...

Since it's all open source, if you're interested to see how this is achieved without spacer views just take a look at the implementation. (It depends on leveraging both the constant and multiplier for the constraints.)

Abstraction means to show only the necessary details to the client of the object

Actually that is encapsulation. also see the first part of the wikipedia article in order to not be confused by encapsulation and data hiding. http://en.wikipedia.org/wiki/Encapsulation_(object-oriented_programming)

keep in mind that by simply hiding all you class members 1:1 behind properties is not encapsulation at all. encapsulation is all about protecting invariants and hiding of implementation details.

here a good article about that. http://blog.ploeh.dk/2012/11/27/Encapsulationofproperties/ also take a look at the articles linked in that article.

classes, properties and access modifiers are tools to provide encapsulation in c#.

you do encapsulation in order to reduce complexity.

Abstraction is "the process of identifying common patterns that have systematic variations; an abstraction represents the common pattern and provides a means for specifying which variation to use" (Richard Gabriel).

Yes, that is a good definition for abstraction.

They are different concepts. Abstraction is the process of refining away all the unneeded/unimportant attributes of an object and keep only the characteristics best suitable for your domain.

Yes, they are different concepts. keep in mind that abstraction is actually the opposite of making an object suitable for YOUR domain ONLY. it is in order to make the object suitable for the domain in general!

if you have a actual problem and provide a specific solution, you can use abstraction to formalize a more generic solution that can also solve more problems that have the same common pattern. that way you can increase the re-usability for your components or use components made by other programmers that are made for the same domain, or even for different domains.

good examples are classes provided by the .net framework, for example list or collection. these are very abstract classes that you can use almost everywhere and in a lot of domains. Imagine if .net only implemented a EmployeeList class and a CompanyList that could only hold a list of employees and companies with specific properties. such classes would be useless in a lot of cases. and what a pain would it be if you had to re-implement the whole functionality for a CarList for example. So the "List" is ABSTRACTED away from Employee, Company and Car. The List by itself is an abstract concept that can be implemented by its own class.

Interfaces, abstract classes or inheritance and polymorphism are tools to provide abstraction in c#.

you do abstraction in order to provide reusability.

In a servlet based artifact, such as @WebServlet, @WebFilter and @WebListener, you can grab a "plain vanilla" JSF @ManagedBean @RequestScoped by:

Bean bean = (Bean) request.getAttribute("beanName");

and @ManagedBean @SessionScoped by:

Bean bean = (Bean) request.getSession().getAttribute("beanName");

and @ManagedBean @ApplicationScoped by:

Bean bean = (Bean) getServletContext().getAttribute("beanName");

Note that this prerequires that the bean is already autocreated by JSF beforehand. Else these will return null. You'd then need to manually create the bean and use setAttribute("beanName", bean).

If you're able to use CDI @Named instead of the since JSF 2.3 deprecated @ManagedBean, then it's even more easy, particularly because you don't anymore need to manually create the beans:

@Inject
private Bean bean;

Note that this won't work when you're using @Named @ViewScoped because the bean can only be identified by JSF view state and that's only available when the FacesServlet has been invoked. So in a filter which runs before that, accessing an @Injected @ViewScoped will always throw ContextNotActiveException.

Only when you're inside @ManagedBean, then you can use @ManagedProperty:

@ManagedProperty("#{bean}")
private Bean bean;

Note that this doesn't work inside a @Named or @WebServlet or any other artifact. It really works inside @ManagedBean only.

If you're not inside a @ManagedBean, but the FacesContext is readily available (i.e. FacesContext#getCurrentInstance() doesn't return null), you can also use Application#evaluateExpressionGet():

FacesContext context = FacesContext.getCurrentInstance();
Bean bean = context.getApplication().evaluateExpressionGet(context, "#{beanName}", Bean.class);

which can be convenienced as follows:

@SuppressWarnings("unchecked")
public static <T> T findBean(String beanName) {
    FacesContext context = FacesContext.getCurrentInstance();
    return (T) context.getApplication().evaluateExpressionGet(context, "#{" + beanName + "}", Object.class);
}

and can be used as follows:

Bean bean = findBean("bean");

See also:

• Backing beans (@ManagedBean) or CDI Beans (@Named)?

I tried Fiddler with its reverse proxy ability which is mentioned by @marxidad and it seems to be working fine, since Fiddler is a familiar UI for me and has the ability to show request/responses in various formats (i.e. Raw, XML, Hex), I accept it as an answer to this question. One thing though. I use WCF and I got the following exception with reverse proxy thing:

The message with To 'http://localhost:8000/path/to/service' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree

I have figured out (thanks Google, erm.. I mean Live Search :p) that this is because my endpoint addresses on server and client differs by port number. If you get the same exception consult to the following MSDN forum message:

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2302537&SiteID=1

which recommends to use clientVia Endpoint Behavior explained in following MSDN article:

My favorite way to do this is with a ValueConverter so that the ItemsSource and SelectedValue both bind to the same property. This requires no additional properties to keep your ViewModel nice and clean.

<ComboBox ItemsSource="{Binding Path=ExampleProperty, Converter={x:EnumToCollectionConverter}, Mode=OneTime}"
          SelectedValuePath="Value"
          DisplayMemberPath="Description"
          SelectedValue="{Binding Path=ExampleProperty}" />

And the definition of the Converter:

public static class EnumHelper
{
  public static string Description(this Enum e)
  {
    return (e.GetType()
             .GetField(e.ToString())
             .GetCustomAttributes(typeof(DescriptionAttribute), false)
             .FirstOrDefault() as DescriptionAttribute)?.Description ?? e.ToString();
  }
}

[ValueConversion(typeof(Enum), typeof(IEnumerable<ValueDescription>))]
public class EnumToCollectionConverter : MarkupExtension, IValueConverter
{
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
  {
    return Enum.GetValues(value.GetType())
               .Cast<Enum>()
               .Select(e => new ValueDescription() { Value = e, Description = e.Description()})
               .ToList();
  }
  public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
  {
    return null;
  }
  public override object ProvideValue(IServiceProvider serviceProvider)
  {
    return this;
  }
}

This converter will work with any enum. ValueDescription is just a simple class with a Value property and a Description property. You could just as easily use a Tuple with Item1 and Item2, or a KeyValuePair with Key and Value instead of Value and Description or any other class of your choice as long as it has can hold an enum value and string description of that enum value.

You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:

1. which python
   output: /usr/bin/python
2. which brew
   output: /usr/local/bin/brew     //so they are different
3. cd /usr/local/lib/python2.7/site-packages
4. ls   //you can see PyQt4 and sip are here
5. Now you need to add usr/local/lib/python2.7/site-packages to your python path.
6. open ~/.bash_profile   //you will open your bash_profile file in your editor
7. Add 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' to your bash file and save it
8. Close your terminal and restart it to reload the shell
9. python
10. import PyQt4    // it is ok now

(I am using JupyterLab with Julia)

First thing is that Jupyter lab from my previous use offers more 'themes' which is great on the eyes, and also fontsize changes independent of the browser, so that makes it closer to that of an IDE. There are some specifics I like such as changing the 'code font size' and leaving the interface font size to be the same.

Major features that are great is

• the drag and drop of cells so that you can easily rearrange the code
• collapsing cells with a single mouse click and a small mark to remind of their placement

What is paramount though is the ability to have split views of the tabs and the terminal. If you use Emacs, then you probably enjoyed having multiple buffers with horizontal and vertical arrangements with one of them running a shell (terminal), and with jupyterlab this can be done, and the arrangement is made with drags and drops which in Emacs is typically done with sets of commands.

(I do not believe that there is a learning curve added to those that have not used the 'notebook' original version first. You can dive straight into this IDE experience)

If you are using Maven, run this command in your project directory

mvn clean package

Virtualenv is your friend

Even if you want to add a package to your primary install, it's still best to do it in a virtual environment first, to ensure compatibility with your other packages. However, if you get familiar with virtualenv, you'll probably find there's really no reason to install anything in your base install.

This is good in the general case:

yourPath.Split(@"\/", StringSplitOptions.RemoveEmptyEntries)

There is no empty element in the returned array if the path itself ends in a (back)slash (e.g. "\foo\bar\"). However, you will have to be sure that yourPath is really a directory and not a file. You can find out what it is and compensate if it is a file like this:

if(Directory.Exists(yourPath)) {
  var entries = yourPath.Split(@"\/", StringSplitOptions.RemoveEmptyEntries);
}
else if(File.Exists(yourPath)) {
  var entries = Path.GetDirectoryName(yourPath).Split(
                    @"\/", StringSplitOptions.RemoveEmptyEntries);
}
else {
  // error handling
}

I believe this covers all bases without being too pedantic. It will return a string[] that you can iterate over with foreach to get each directory in turn.

If you want to use constants instead of the @"\/" magic string, you need to use

var separators = new char[] {
  Path.DirectorySeparatorChar,  
  Path.AltDirectorySeparatorChar  
};

and then use separators instead of @"\/" in the code above. Personally, I find this too verbose and would most likely not do it.

You need to use runat="server" like this:

<textarea id="TextArea1" cols="20" rows="2" runat="server"></textarea>

You can use the runat=server attribute with any standard HTML element, and later use it from codebehind.

The function you're looking for is 'Insert'. It takes as its parameters the index you want to insert at, and an array of values to use for the new row values. Typical usage might include:

myDataGridView.Rows.Insert(4,new object[]{value1,value2,value3});

or something to that effect.

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

From microsoft documentation, you can create file if not exist and append to it in a single call File.AppendAllText Method (String, String)

I spent quite a bit of time also looking to launch a simple Python program at 01:00. For some reason, I couldn't get cron to launch it and APScheduler seemed rather complex for something that should be simple. Schedule (https://pypi.python.org/pypi/schedule) seemed about right.

You will have to install their Python library:

pip install schedule

This is modified from their sample program:

import schedule
import time

def job(t):
    print "I'm working...", t
    return

schedule.every().day.at("01:00").do(job,'It is 01:00')

while True:
    schedule.run_pending()
    time.sleep(60) # wait one minute

You will need to put your own function in place of job and run it with nohup, e.g.:

nohup python2.7 MyScheduledProgram.py &

Don't forget to start it again if you reboot.

This worked on Sublime 3:

To browse html files with default app by Alt+L hotkey:

Add this line to Preferences -> Key Bindings - User opening file:

{ "keys": ["alt+l"], "command": "open_in_browser"}

To browse or open with external app like chrome:

Add this line to Tools -> Build System -> New Build System... opening file, and save with name "OpenWithChrome.sublime-build"

"shell_cmd": "C:\\PROGRA~1\\Google\\Chrome\\APPLIC~1\\chrome.exe $file"

Then you can browse/open the file by selecting Tools -> Build System -> OpenWithChrome and pressing F7 or Ctrl+B key.

C++20 will have "uniform container erasure", and you'll be able to write:

std::erase_if(numbers, [](int n){ return n % 2 == 0 });

And that will work for vector, set, deque, etc. See cppReference for more info.

If you want to do multiple (3+) columns here is a great snippet that works perfectly and validates as valid HTML5:

Use a literal control and write your html like this:

literal1.text = "<h2><p>Notify:</p> alert</h2>";

It's quite easy. Just write this, for example:

npm install -g [email protected]

Or:

npm install -g npm@latest    // For the last stable version
npm install -g npm@next      // For the most recent release

What works for me is that: File > Import > Existing Project into Workspace (under General tab), then choose the project root folder. The importing of Existing Android Code into Workspace somehow does not work on Eclipse for me.

It's Ctrl+Shift+O / Cmd+Shift+O on mac. You can see it if you close all tabs

For me : I have a white space in my path's folder name G:\Other Imp Projects\Mi.....

Solution 1 :

Remove white space from folder

Example: Other Imp Projects ->> Other_Imp_Projects

Solution 2:

add Quote ("") for your path.

Example: mkdir "$(ProjectDir)$(OutDir)Configurations" //see double quotes

Below query seems to work good for me in SQL Server database:

select column, COUNT(column) AS MOST_FREQUENT
from TABLE_NAME
GROUP BY column
ORDER BY COUNT(column) DESC

Result:

column          MOST_FREQUENT
item1           highest count
item2           second highest 
item3           third higest
..
..

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

Reference: https://pypi.org/project/chromedriver-binary/

1st Option

date_trunc('month', timestamp_column)::date

It will maintain the date format with all months starting at day one.

Example:

2016-08-01
2016-09-01
2016-10-01
2016-11-01
2016-12-01
2017-01-01

2nd Option

to_char(timestamp_column, 'YYYY-MM')

This solution proposed by @yairchu worked fine in my case. I really wanted to discard 'day' info.

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

This borrows from a few other answers here but I thought it might help someone. If you define the following function on your custom object, then you have a factory function that you can pass a generic object into and it will return for you an instance of the class.

CustomObject.create = function (obj) {
    var field = new CustomObject();
    for (var prop in obj) {
        if (field.hasOwnProperty(prop)) {
            field[prop] = obj[prop];
        }
    }

    return field;
}

Use like this

var typedObj = CustomObject.create(genericObj);

I have a solution for this but not sure on the reason why this would be different from one environment to the other - although one big difference between the two environments is WSS svc pack 1 was installed on the environment where the error was occurring.

To fix this issue I got a good clue from this link - http://silverlight.net/forums/t/22787.aspx ie to "please check the Xml Schema of your service" and "the sequence in the schema is sorted alphabetically"

Looking at the wsdl generated I noticed that for the serialized class that was causing the error, the properties of this class were not visible in the wsdl.

The Definition of the class had private setters for most of the properties, but not for CustomFields property ie..

[Serializable]
public class FileMetaDataDto
{
    .
    . a constructor...   etc and several other properties edited for brevity
    . 

    public int Id { get; private set; }
    public string Version { get; private set; }
    public List<MetaDataValueDto> CustomFields { get; set; }

}

On removing private from the setter and redeploying the service then looking at the wsdl again, these properties were now visible, and the original error was fixed.

So the wsdl before update was

- <s:complexType name="ArrayOfFileMetaDataDto">
- <s:sequence>
  <s:element minOccurs="0" maxOccurs="unbounded" name="FileMetaDataDto" nillable="true" type="tns:FileMetaDataDto" /> 
  </s:sequence>
  </s:complexType>
- <s:complexType name="FileMetaDataDto">
- <s:sequence>
  <s:element minOccurs="0" maxOccurs="1" name="CustomFields" type="tns:ArrayOfMetaDataValueDto" /> 
  </s:sequence>
  </s:complexType>

The wsdl after update was

- <s:complexType name="ArrayOfFileMetaDataDto">
- <s:sequence>
  <s:element minOccurs="0" maxOccurs="unbounded" name="FileMetaDataDto" nillable="true" type="tns:FileMetaDataDto" /> 
  </s:sequence>
  </s:complexType>
- <s:complexType name="FileMetaDataDto">
- <s:sequence>
  <s:element minOccurs="1" maxOccurs="1" name="Id" type="s:int" /> 
  <s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="Title" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="ContentType" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="Icon" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="ModifiedBy" type="s:string" /> 
  <s:element minOccurs="1" maxOccurs="1" name="ModifiedDateTime" type="s:dateTime" /> 
  <s:element minOccurs="1" maxOccurs="1" name="FileSizeBytes" type="s:int" /> 
  <s:element minOccurs="0" maxOccurs="1" name="Url" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="RelativeFolderPath" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="DisplayVersion" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="Version" type="s:string" /> 
  <s:element minOccurs="0" maxOccurs="1" name="CustomFields" type="tns:ArrayOfMetaDataValueDto" /> 
  <s:element minOccurs="0" maxOccurs="1" name="CheckoutBy" type="s:string" /> 
  </s:sequence>
  </s:complexType>

An example I found somewhere here in the past. Might be of some help:

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

public class Form1 : Form
{
   [DllImport("user32.dll",CharSet=CharSet.Auto, CallingConvention=CallingConvention.StdCall)]
   public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
   //Mouse actions
   private const int MOUSEEVENTF_LEFTDOWN = 0x02;
   private const int MOUSEEVENTF_LEFTUP = 0x04;
   private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
   private const int MOUSEEVENTF_RIGHTUP = 0x10;

   public Form1()
   {
   }

   public void DoMouseClick()
   {
      //Call the imported function with the cursor's current position
      uint X = (uint)Cursor.Position.X;
      uint Y = (uint)Cursor.Position.Y;
      mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
   }

   //...other code needed for the application
}

Can use app:hintTextColor if you use com.google.android.material.textfield.TextInputLayout, try this

 <com.google.android.material.textfield.TextInputLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:hint="@string/app_name" 
     app:hintTextColor="@android:color/white">                   

     <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />
 </com.google.android.material.textfield.TextInputLayout>

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

I have seen such error and i solved it. You may have missing values in your data set. Number of observations in every column must also be the same.

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

I was able to update it with markForCheck()

Import ChangeDetectorRef

import { ChangeDetectorRef } from '@angular/core';

Inject and instantiate it

constructor(private ref: ChangeDetectorRef) { 
}

Finally mark change detection to take place

this.ref.markForCheck();

Here's an example where markForCheck() works and detectChanges() don't.

EDIT: This example doesn't portray the problem anymore :( I believe it might be running a newer Angular version where it's fixed.

(Press STOP/RUN to run it again)

Having looked around a lot including links from this page i found this great article, using moment timezone:

https://www.webniraj.com/2016/11/23/javascript-using-moment-js-to-display-dates-times-in-users-timezone/

To summarise it:

Get the user's timezone

var tz = moment.tz.guess();
console.info('Timezone: ' + tz);

Returns eg: Timezone: Europe/London

Set the default user timezone

moment.tz.setDefault(tz);

Set custom timezone

moment.tz.setDefault('America/Los_Angeles');

Convert date / time to local timezone, assumes original date/time is in UTC

moment.utc('2016-12-25 07:00').tz(tz).format('ddd, Do MMMM YYYY, h:mma');

Returns: Sun, 25th December 2016, 7:00am

Convert date/time to LA Time

moment.utc('2016-12-25 07:00').tz('America/Los_Angeles').format('ddd, Do MMMM YYYY, h:mma');

Returns: Sat, 24th December 2016, 11:00pm

Convert from LA time to London

moment.tz('2016-12-25 07:00', 'America/Los_Angeles').tz('Europe/London').format( 'ddd, Do MMMM YYYY, h:mma' );

Returns: Sun, 25th December 2016, 3:00pm

I would like to add another Bootstrap 4 solution. One that worked for me.

The CSS "Order" property, combined with a media query, can be used to re-order columns when they get stacked in smaller screens.

Something like this:

@media only screen and (max-width: 768px) {
    #first {
        order: 2;
    }
    #second {
        order: 4;
    }
    #third {
        order: 1;
    }
    #fourth {
        order: 3;
    }
}

CodePen Link: https://codepen.io/preston206/pen/EwrXqm

Adjust the screen size and you'll see the columns get stacked in a different order.

I'll tie this in with the original poster's question. With CSS, the navbar, sidebar, and content can be targeted and then order properties applied within a media query.
