I followed the link shared by lisachenko and found another link to this blog: http://guilhembichot.blogspot.co.uk/2013/11/with-recursive-and-mysql.html

The post lays out ways of emulating the 2 uses of SQL WITH. Really good explanation on how these work to do a similar query as SQL WITH.

1) Use WITH so you don't have to perform the same sub query multiple times

CREATE VIEW D AS (SELECT YEAR, SUM(SALES) AS S FROM T1 GROUP BY YEAR);
SELECT D1.YEAR, (CASE WHEN D1.S>D2.S THEN 'INCREASE' ELSE 'DECREASE' END) AS TREND
FROM
 D AS D1,
 D AS D2
WHERE D1.YEAR = D2.YEAR-1;
DROP VIEW D;

2) Recursive queries can be done with a stored procedure that makes the call similar to a recursive with query.

CALL WITH_EMULATOR(
"EMPLOYEES_EXTENDED",
"
  SELECT ID, NAME, MANAGER_ID, 0 AS REPORTS
  FROM EMPLOYEES
  WHERE ID NOT IN (SELECT MANAGER_ID FROM EMPLOYEES WHERE MANAGER_ID IS NOT NULL)
",
"
  SELECT M.ID, M.NAME, M.MANAGER_ID, SUM(1+E.REPORTS) AS REPORTS
  FROM EMPLOYEES M JOIN EMPLOYEES_EXTENDED E ON M.ID=E.MANAGER_ID
  GROUP BY M.ID, M.NAME, M.MANAGER_ID
",
"SELECT * FROM EMPLOYEES_EXTENDED",
0,
""
);

And this is the code or the stored procedure

# Usage: the standard syntax:
#   WITH RECURSIVE recursive_table AS
#    (initial_SELECT
#     UNION ALL
#     recursive_SELECT)
#   final_SELECT;
# should be translated by you to 
# CALL WITH_EMULATOR(recursive_table, initial_SELECT, recursive_SELECT,
#                    final_SELECT, 0, "").

# ALGORITHM:
# 1) we have an initial table T0 (actual name is an argument
# "recursive_table"), we fill it with result of initial_SELECT.
# 2) We have a union table U, initially empty.
# 3) Loop:
#   add rows of T0 to U,
#   run recursive_SELECT based on T0 and put result into table T1,
#   if T1 is empty
#      then leave loop,
#      else swap T0 and T1 (renaming) and empty T1
# 4) Drop T0, T1
# 5) Rename U to T0
# 6) run final select, send relult to client

# This is for *one* recursive table.
# It would be possible to write a SP creating multiple recursive tables.

See Oracle's docs on SELECT to see how subquery factoring works, and Mark's example:

WITH employee AS (SELECT * FROM Employees)
SELECT * FROM employee WHERE ID < 20
UNION ALL
SELECT * FROM employee WHERE Sex = 'M'

Windows:

1. Go to C:\Python27\Lib\site-packages\ find the folder wx-<version>-msw or similar

2. Move the wx from the above folder to C:\Python27\Lib\site-packages\

The values of form elements including type='hidden' are submitted to the server when the form is posted. input type="hidden" values are not visible in the page. Maintaining User IDs in hidden fields, for example, is one of the many uses.

SO uses a hidden field for the upvote click.

<input value="16293741" name="postId" type="hidden">

Using this value, the server-side script can store the upvote.

You can just redirect in your success handler, like this:

window.location.href = "thankyou.php";

Or since you're displaying results, wait a few seconds, for example this would wait 2 seconds:

setTimeout(function() {
  window.location.href = "thankyou.php";
}, 2000);

Here's a simpler way:

a = [-2,1,5,3,8,5,6]
b = [1,2,5]
c = [e for i, e in enumerate(a) if i in b]

\r used for carriage return. (ASCII value is 13) \n used for new line. (ASCII value is 10)

SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.

1. BEGIN TRANSACTION;
2. CREATE TEMPORARY TABLE t1_backup(a,b);
3. INSERT INTO t1_backup SELECT a,b FROM t1;
4. DROP TABLE t1;
5. CREATE TABLE t1(a,b);
6. INSERT INTO t1 SELECT a,b FROM t1_backup;
7. DROP TABLE t1_backup;
8. COMMIT

For more detail you can refer the link.

$(function() {
 $("#MyTextBox").blur();
});

Advantages of a PreparedStatement:

• Precompilation and DB-side caching of the SQL statement leads to overall faster execution and the ability to reuse the same SQL statement in batches.

• Automatic prevention of SQL injection attacks by builtin escaping of quotes and other special characters. Note that this requires that you use any of the PreparedStatement setXxx() methods to set the values

  preparedStatement = connection.prepareStatement("INSERT INTO Person (name, email, birthdate, photo) VALUES (?, ?, ?, ?)");
  preparedStatement.setString(1, person.getName());
  preparedStatement.setString(2, person.getEmail());
  preparedStatement.setTimestamp(3, new Timestamp(person.getBirthdate().getTime()));
  preparedStatement.setBinaryStream(4, person.getPhoto());
  preparedStatement.executeUpdate();
  

  and thus don't inline the values in the SQL string by string-concatenating.

  preparedStatement = connection.prepareStatement("INSERT INTO Person (name, email) VALUES ('" + person.getName() + "', '" + person.getEmail() + "'");
  preparedStatement.executeUpdate();
  

• Eases setting of non-standard Java objects in a SQL string, e.g. Date, Time, Timestamp, BigDecimal, InputStream (Blob) and Reader (Clob). On most of those types you can't "just" do a toString() as you would do in a simple Statement. You could even refactor it all to using PreparedStatement#setObject() inside a loop as demonstrated in the utility method below:

  public static void setValues(PreparedStatement preparedStatement, Object... values) throws SQLException {
      for (int i = 0; i < values.length; i++) {
          preparedStatement.setObject(i + 1, values[i]);
      }
  }
  

  Which can be used as below:

  preparedStatement = connection.prepareStatement("INSERT INTO Person (name, email, birthdate, photo) VALUES (?, ?, ?, ?)");
  setValues(preparedStatement, person.getName(), person.getEmail(), new Timestamp(person.getBirthdate().getTime()), person.getPhoto());
  preparedStatement.executeUpdate();
  

You need to wrap your form processing code in a conditional so it doesn't run when you first open the page. Something like so:

if($_POST['num1'] > 0 && $_POST['num2'] > 0 && $_POST['num3'] > 0 && $_POST['num4'] > 0){

  $itemQty = $_POST['num1'];
  $itemCost = $_POST['num2'];
  $itemSale = $_POST['num3'];
  $shipMat = $_POST['num4'];

  $diffPrice = $itemSale - $itemCost;
  $actual = ($diffPrice - $shipMat) * $itemQty;
  $diffPricePercent = (($actual * 100) / $itemCost) / $itemQty ;
}

Spring have the IoC container which carry the Bag of Bean ; creation maintain and deletion are the responsibilities of Spring Container. We can put the bean in to Spring by Wiring and Auto Wiring. Wiring mean we manually configure it into the XML file and "Auto Wiring" mean we put the annotations in the Java file then Spring automatically scan the root-context where java configuration file, make it and put into the bag of Spring.

Here is the detail URI where you got more information about Beans

This is how you do it:

function view($view)
{
    $ms = Person::where('name', '=', 'Foo Bar')->first();

    $persons = Person::order_by('list_order', 'ASC')->get();

    return $view->with('persons', $persons)->with('ms', $ms);
}

You can also use compact():

function view($view)
{
    $ms = Person::where('name', '=', 'Foo Bar')->first();

    $persons = Person::order_by('list_order', 'ASC')->get();

    return $view->with(compact('persons', 'ms'));
}

Or do it in one line:

function view($view)
{
    return $view
            ->with('ms', Person::where('name', '=', 'Foo Bar')->first())
            ->with('persons', Person::order_by('list_order', 'ASC')->get());
}

Or even send it as an array:

function view($view)
{
    $ms = Person::where('name', '=', 'Foo Bar')->first();

    $persons = Person::order_by('list_order', 'ASC')->get();

    return $view->with('data', ['ms' => $ms, 'persons' => $persons]));
}

But, in this case, you would have to access them this way:

{{ $data['ms'] }}

Found transport-attribute in binding-element which tells us that this is the WSDL 1.1 binding for the SOAP 1.1 HTTP binding.

ex.

<wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

1)event.stopPropagation(): =>It is used to stop executions of its corresponding parent handler only.

2) event.stopImmediatePropagation(): => It is used to stop the execution of its corresponding parent handler and also handler or function attached to itself except the current handler. => It also stops all the handler attached to the current element of entire DOM.

Here is the example: Jsfiddle!

If there is an interface anywhere in the ThreadProvider hierarchy try putting the name of the Interface as the type of your service provider, eg. if you have say this structure:

public class ThreadProvider implements CustomInterface{
...
}

Then in your controller try this:

@Controller
public class ChiusuraController {

    @Autowired
    private CustomInterface chiusuraProvider;
}

The reason why this is happening is, in your first case when you DID NOT have ChiusuraProvider extend ThreadProvider Spring probably was underlying creating a CGLIB based proxy for you(to handle the @Transaction).

When you DID extend from ThreadProvider assuming that ThreadProvider extends some interface, Spring in that case creates a Java Dynamic Proxy based Proxy, which would appear to be an implementation of that interface instead of being of ChisuraProvider type.

If you absolutely need to use ChisuraProvider you can try AspectJ as an alternative or force CGLIB based proxy in the case with ThreadProvider also this way:

<aop:aspectj-autoproxy proxy-target-class="true"/>

Here is some more reference on this from the Spring Reference site: http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/classic-aop-spring.html#classic-aop-pfb

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";

If this example can help, adds a "custom confirm popin" on some links (I keep the code of "$.ui.Modal.confirm", it's just an exemple for the callback that executes the original action) :

//Register "custom confirm popin" on click on specific links
$(document).on(
    "click", 
    "A.confirm", 
    function(event){
        //prevent default click action
        event.preventDefault();
        //show "custom confirm popin"
        $.ui.Modal.confirm(
            //popin text
            "Do you confirm ?", 
            //action on click 'ok'
            function() {
                //Unregister handler (prevent loop)
                $(document).off("click", "A.confirm");
                //Do default click action
                $(event.target)[0].click();
            }
        );
    }
);

You're saying you want a "serverless" solution. But that means you have no ability to put any of "your" code in the loop. (NOTE: Once you give your code to a client, it's "their" code now.) Locking down CORS is not going to help: People can easily write a non-web-based tool (or a web-based proxy) that adds the correct CORS header to abuse your system.

The big problem is that you can't differentiate between the different users. You can't allow one user to list/access his files, but prevent others from doing so. If you detect abuse, there is nothing you can do about it except change the key. (Which the attacker can presumably just get again.)

Your best bet is to create an "IAM user" with a key for your javascript client. Only give it write access to just one bucket. (but ideally, do not enable the ListBucket operation, that will make it more attractive to attackers.)

If you had a server (even a simple micro instance at $20/month), you could sign the keys on your server while monitoring/preventing abuse in realtime. Without a server, the best you can do is periodically monitor for abuse after-the-fact. Here's what I would do:

1) periodically rotate the keys for that IAM user: Every night, generate a new key for that IAM user, and replace the oldest key. Since there are 2 keys, each key will be valid for 2 days.

2) enable S3 logging, and download the logs every hour. Set alerts on "too many uploads" and "too many downloads". You will want to check both total file size and number of files uploaded. And you will want to monitor both the global totals, and also the per-IP address totals (with a lower threshold).

These checks can be done "serverless" because you can run them on your desktop. (i.e. S3 does all the work, these processes just there to alert you to abuse of your S3 bucket so you don't get a giant AWS bill at the end of the month.)

This can now be done as of docker-compose v2+ as part of the build object;

docker-compose.yml

version: '2'
services:
    my_image_name:
        build:
            context: . #current dir as build context
            args:
                var1: 1
                var2: c

See the docker compose docs.

In the above example "var1" and "var2" will be sent to the build environment.

Note: any env variables (specified by using the environment block) which have the same name as args variable(s) will override that variable.

Use SimpleDateFormat class. Take a look on its javadoc: it explains how to use format switches.

Step1

In your Dockerfile, you can use the verb EXPOSE to expose multiple ports.
e.g.

EXPOSE 3000 80 443 22

Step2

You then would like to build an new image based on above Dockerfile.
e.g.

docker build -t foo:tag .

Step3

Then you can use the -p to map host port with the container port, as defined in above EXPOSE of Dockerfile.
e.g.

docker run -p 3001:3000 -p 23:22

In case you would like to expose a range of continuous ports, you can run docker like this:

docker run -it -p 7100-7120:7100-7120/tcp 

Follow these steps:

1. Git stash save will save all your changes even if you switch between branches.

git stash save

2. Git checkout any other branch, now since you saved your changes you can move around any branch. The above command will make sure that your changes are saved.

git checkout branch

3. Now when you come back to the branch use this command to get all your changes back.

git stash pop

Use np.select if you have multiple conditions to be checked from the dataframe and output a specific choice in a different column

conditions=[(condition1),(condition2)]
choices=["choice1","chocie2"]

df["new column"]=np.select=(condtion,choice,default=)

Note: No of conditions and no of choices should match, repeat text in choice if for two different conditions you have same choices

Also worth noting that WinFlexBison has been packaged for the Chocolatey package manager. Install that and then go:

choco install winflexbison

...which at the time of writing contains Bison 2.7 & Flex 2.6.3.

There is also winflexbison3 which (at the time of writing) has Bison 3.0.4 & Flex 2.6.3.

Working encode/decode functions in python3 (adapted very little from qneill's answer):

def encode(key, clear):
    enc = []
    for i in range(len(clear)):
        key_c = key[i % len(key)]
        enc_c = (ord(clear[i]) + ord(key_c)) % 256
        enc.append(enc_c)
    return base64.urlsafe_b64encode(bytes(enc))

def decode(key, enc):
    dec = []
    enc = base64.urlsafe_b64decode(enc)
    for i in range(len(enc)):
        key_c = key[i % len(key)]
        dec_c = chr((256 + enc[i] - ord(key_c)) % 256)
        dec.append(dec_c)
    return "".join(dec)

Select-Object returns a custom PSObject with just the properties specified. Even with a single property, you don't get the ACTUAL variable; it is wrapped inside the PSObject.

Instead, do:

Get-Date | Select-Object -ExpandProperty DayOfWeek

That will get you the same result as:

(Get-Date).DayOfWeek

The difference is that if Get-Date returns multiple objects, the pipeline way works better than the parenthetical way as (Get-ChildItem), for example, is an array of items. This has changed in PowerShell v3 and (Get-ChildItem).FullPath works as expected and returns an array of just the full paths.

        string nameOfString = (string.Join(",", name.Select(x => x.ToString()).ToArray()));

New answer to old question

None of the existing answers to this old question address the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD. The fix is to use xs:simpleContent first. Details follow...

Your XML,

<price currency="euros">20000.00</price>

will be valid against either of the following corrected XSDs:

Locally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency">
            <xs:simpleType>
              <xs:restriction base="xs:string">
                <xs:enumeration value="pounds" />
                <xs:enumeration value="euros" />
                <xs:enumeration value="dollars" />
              </xs:restriction>
            </xs:simpleType>
          </xs:attribute>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Globally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:simpleType name="currencyType">
    <xs:restriction base="xs:string">
      <xs:enumeration value="pounds" />
      <xs:enumeration value="euros" />
      <xs:enumeration value="dollars" />
    </xs:restriction>
  </xs:simpleType>

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency" type="currencyType"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Notes

• As commented by @Paul, these do change the content type of price from xs:string to xs:decimal, but this is not strictly necessary and was not the real problem.
• As answered by @user998692, you could separate out the definition of currency, and you could change to xs:decimal, but this too was not the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD; xs:simpleContent is needed first.

A related matter (that wasn't asked but may have confused other answers):

How could price be restricted given that it has an attribute?

In this case, a separate, global definition of priceType would be needed; it is not possible to do this with only local type definitions.

The problem is that you are trying to insert data into the database without using columns. Sql server gives you that error message.

error: insert into users values('1', '2','3') - this works fine as long you only have 3 columns

if you have 4 columns but only want to insert into 3 of them

correct: insert into users (firstName,lastName,city) values ('Tom', 'Jones', 'Miami')

hope this helps

From the manual:

To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:

SELECT * FROM tbl LIMIT 95,18446744073709551615;

Obviously, you should replace 95 by 10. The large number they use is 2^64 - 1, by the way.

 <td rowspan="2" style="text-align:left;vertical-align:top;padding:0">Save a lot</td>

That should do it.

Try export PYTHONHOME=/usr/local. Python should be installed in /usr/local on OS X.

This answer has received a little more attention than I anticipated, I'll add a little bit more context.

Normally, Python looks for its libraries in the paths prefix/lib and exec_prefix/lib, where prefix and exec_prefix are configuration options. If the PYTHONHOME environment variable is set, then the value of prefix and exec_prefix are inherited from it. If the PYTHONHOME environment variable is not set, then prefix and exec_prefix default to /usr/local (and I believe there are other ways to set prefix/exec_prefix as well, but I'm not totally familiar with them).

Normally, when you receive the error message Could not find platform independent libraries <prefix>, the string <prefix> would be replaced with the actual value of prefix. However, if prefix has an empty value, then you get the rather cryptic messages posted in the question. One way to get an empty prefix would be to set PYTHONHOME to an empty string. More info about PYTHONHOME, prefix, and exec_prefix is available in the official docs.

Do not use this code; whoever wrote it clearly has a fundamental misunderstanding of the language and is not trustworthy. The expression:

j >= 0, i <= 5

evaluates "j >= 0", then throws it away and does nothing with it. Then it evaluates "i <= 5" and uses that, and only that, as the condition for ending the loop. The comma operator can be used meaningfully in a loop condition when the left operand has side effects; you'll often see things like:

for (i = 0, j = 0; i < 10; ++i, ++j) . . .

in which the comma is used to sneak in extra initialization and increment statements. But the code shown is not doing that, or anything else meaningful.

Clean way which I found useful

git revert --no-commit HEAD~3..

This command reverts last 3 commits with only one commit.

Also doesn't rewrite history.

The .. helps create a range. Meaning HEAD~3.. is the same as HEAD~3..HEAD

its simple go to the folder where your all java code is saved say E:/javaFolder and then javadoc *.java

I wanted an "expand/collapse" container with a plus and minus button to open and close it. This uses the standard bootstrap event and has animation. This is BS3.

HTML:

<button id="button" type="button" class="btn btn-primary" 
  data-toggle="collapse" data-target="#demo">
  <span class="glyphicon glyphicon-collapse-down"></span> Show
</button>

<div id="demo" class="collapse">
  <ol class="list-group">
      <li class="list-group-item">Warrior</li>
      <li class="list-group-item">Adventurer</li>
      <li class="list-group-item">Mage</li>
  </ol>
</div>

JS:

$(function(){
  $('#demo').on('hide.bs.collapse', function () {
    $('#button').html('<span class="glyphicon glyphicon-collapse-down"></span> Show');
  })
  $('#demo').on('show.bs.collapse', function () {
    $('#button').html('<span class="glyphicon glyphicon-collapse-up"></span> Hide');
  })
})

Example:

The following function will work in JDK version 1.5 and above.

public String getSimpleName()

As per Object oriented concept Interface implemented by classes and have contract to access these implemented function(or methods) using object.

So if you want to access Interface Contract methods you have to create object. It is always must that is not allowed in case of Static methods. Static classes ,method and variables never require objects and load in memory without creating object of that area(or class) or you can say do not require Object Creation.

I have on several projects.

The biggest difference in my opinion

• jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old

• Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding

• jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)

So what to choose?

That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?

I always end up using both, so I can use the best of both worlds.

Here are the links to both frameworks, if you decide to use them.

1. jQuery UI
2. Bootstrap

In Javascript I would use /.*_/, meaning: match everything until _ (including)

Example:

console.log( 'hello_world'.replace(/.*_/,'') ) // 'world'

This one helped me:

To hide the prompt set xls.DisplayAlerts = False

ConflictResolution is not a true or false property, it should be xlLocalSessionChanges

Note that this has nothing to do with displaying the Overwrite prompt though!

Set xls = CreateObject("Excel.Application")    
xls.DisplayAlerts = False
Set wb = xls.Workbooks.Add
fullFilePath = importFolderPath & "\" & "A.xlsx"

wb.SaveAs fullFilePath, AccessMode:=xlExclusive,ConflictResolution:=Excel.XlSaveConflictResolution.xlLocalSessionChanges    
wb.Close (True)

foo(*ob);

You don't need to cast it because it's the same Object type, you just need to dereference it.

You can dispatch a click event, though this is not the same as a real click. For instance, it can't be used to trick a cross-domain iframe document into thinking it was clicked.

All modern browsers support document.elementFromPoint and HTMLElement.prototype.click(), since at least IE 6, Firefox 5, any version of Chrome and probably any version of Safari you're likely to care about. It will even follow links and submit forms:

document.elementFromPoint(x, y).click();

https://developer.mozilla.org/En/DOM:document.elementFromPoint https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click

The one that I like is HexEdit Quick and easy to use

Curl is a non-java program and must be provided outside your Java program.

You can easily get much of the functionality using Jakarta Commons Net, unless there is some specific functionality like "resume transfer" you need (which is tedious to code on your own)

You have two options for concatenating strings in Oracle:

• CONCAT
• Using ||

CONCAT example:

CONCAT(
  CONCAT(
    CONCAT(
      CONCAT(
        CONCAT('I like ', t.type_desc_column), 
        ' cake with '), 
      t.icing_desc_column),
    ' and a '),
  t.fruit_desc_column)

Using || example:

'I like ' || t.type_desc_column || ' cake with ' || t.icing_desc_column || ' and a ' || t.fruit_desc_column

Hi - I want to write a test to establish that an Exception is not raised in a given circumstance.

That's the default assumption -- exceptions are not raised.

If you say nothing else, that's assumed in every single test.

You don't have to actually write an any assertion for that.

This one works with Firefox 43.0 (older not tested):

dl.js:

function download() {
  var msg="Hello world!";
  var blob = new File([msg], "hello.bin", {"type": "application/octet-stream"});

  var a = document.createElement("a");
  a.href = URL.createObjectURL(blob);

  window.location.href=a;
}

dl.html

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>
    <meta charset="utf-8"/>
    <title>Test</title>
    <script type="text/javascript" src="dl.js"></script>
</head>

<body>
<button id="create" type="button" onclick="download();">Download</button>
</body>
</html>

If button is clicked it offered a file named hello.bin for download. Trick is to use File instead of Blob.

For those of us who did not see -1 by Michal Chaniewski, the complete line of code:

cmd.Parameters.Add("@blah",SqlDbType.VarChar,-1).Value = "some large text";

The only built-in way to "downgrade" a database from one SQL Server version to a lower one is the hard way: Script out the whole database, schema and data, then execute the script on the target server.

This is do-able but tends to be brutal.

Motti is right about the order, but there are some other things to consider:

Compilers typically use a hidden flag variable to indicate if the local statics have already been initialized, and this flag is checked on every entry to the function. Obviously this is a small performance hit, but what's more of a concern is that this flag is not guaranteed to be thread-safe.

If you have a local static as above, and foo is called from multiple threads, you may have race conditions causing plonk to be initialized incorrectly or even multiple times. Also, in this case plonk may get destructed by a different thread than the one which constructed it.

Despite what the standard says, I'd be very wary of the actual order of local static destruction, because it's possible that you may unwittingly rely on a static being still valid after it's been destructed, and this is really difficult to track down.

You need to hook to console exit event and not your process.

Capture console exit C#

Here is an example to run a webdev service in Docker. The image's name is morrisjobke/webdav. You can pull it from Docker Hub.

After you run these images, you can then access the WebDAV instance at http://localhost:8888/webdav. Internally the folder /var/webdav is used as the WebDAV root.

You can run this container in the following way:

$ docker run -d -e USERNAME=test -e PASSWORD=test -p 8888:80 morrisjobke/webdav

For Windows, I've created a build.cmd file:

(replace the keystore path and alias)

For Cordova:

@echo off 
set /P spassw="Store Password: " && set /P kpassw="Key Password: " && cordova build android --release -- --keystore=../../local/my.keystore --storePassword=%spassw% --alias=tmpalias --password=%kpassw%

And for Ionic:

@echo off 
set /P spassw="Store Password: " && set /P kpassw="Key Password: " && ionic build --prod && cordova build android --release -- --keystore=../../local/my.keystore --storePassword=%spassw% --alias=tmpalias --password=%kpassw%

Save it in the ptoject's directory, you can double click or open it with cmd.

If you want to copy your static files you can use the file-loader in this way :

for html files :

in webpack.config.js :

module.exports = {
    ...
    module: {
        loaders: [
            { test: /\.(html)$/,
              loader: "file?name=[path][name].[ext]&context=./app/static"
            }
        ]
    }
};

in your js file :

  require.context("./static/", true, /^\.\/.*\.html/);

./static/ is relative to where your js file is.

You can do the same with images or whatever. The context is a powerful method to explore !!

Construct your method to accept it-

public <T> void printClassNameAndCreateList(Class<T> className){
    //example access 1
    System.out.print(className.getName());

    //example access 2
    ArrayList<T> list = new ArrayList<T>();
    //note that if you create a list this way, you will have to cast input
    list.add((T)nameOfObject);
}

Call the method-

printClassNameAndCreateList(SomeClass.class);

You can also restrict the type of class, for example, this is one of the methods from a library I made-

protected Class postExceptionActivityIn;

protected <T extends PostExceptionActivity>  void  setPostExceptionActivityIn(Class <T> postExceptionActivityIn) {
    this.postExceptionActivityIn = postExceptionActivityIn;
}

For more information, search Reflection and Generics.

Inside your function for the click action use

$( "#tabs" ).tabs({ active: # });

Where # is replaced by the tab index you want to select.

It's not well known that you can also inject a Map of the path variables using the @PathVariable annotation. I'm not sure if this feature is available in Spring 3.0 or if it was added later, but here is another way to solve the example:

@RequestMapping(value={ "/json/{type}", "/json" }, method=RequestMethod.GET)
public @ResponseBody TestBean typedTestBean(
    @PathVariable Map<String, String> pathVariables,
    @RequestParam("track") String track) {

    if (pathVariables.containsKey("type")) {
        return new TestBean(pathVariables.get("type"));
    } else {
        return new TestBean();
    }
}

Nice answers abowe, but don't forget one IMPORTANT thing - they provide different results!

  var idList = new int[1, 2, 2, 2, 2]; // same user is selected 4 times
  var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e)).ToList();

This will return 2 rows from DB (and this could be correct, if you just want a distinct sorted list of users)

BUT in many cases, you could want an unsorted list of results. You always have to think about it like about a SQL query. Please see the example with eshop shopping cart to illustrate what's going on:

  var priceListIDs = new int[1, 2, 2, 2, 2]; // user has bought 4 times item ID 2
  var shoppingCart = _dataContext.ShoppingCart
                     .Join(priceListIDs, sc => sc.PriceListID, pli => pli, (sc, pli) => sc)
                     .ToList();

This will return 5 results from DB. Using 'contains' would be wrong in this case.

Because the compiler needs to see them in order to inline them. And headers files are the "components" which are commonly included in other translation units.

#include "file.h"
// Ok, now me (the compiler) can see the definition of that inline function. 
// So I'm able to replace calls for the actual implementation.

In your connection string replace server=localhost with "server = Paul-PC\\SQLEXPRESS;"

If column is autoincremented in sql server then to see the current autoincremented value, and if you want to edit that value for that column use the following query.

-- to get current value
select ident_current('Table_Name')

-- to update current value
dbcc checkident ('[Table_Name]',reseed,"Your Value")

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

This doesn't seem to have <a> </a> tags so selenium might not be able to detect it as a link.

You may try and use

driver.findElement(By.xpath("//*[@class='ng-binding']")).click();

if this is the only element in that page with this class .

CA's don't ask for your private keys! They only asks for CSR to issue a certificate for you.

If they have your private key, it's possible that your SSL certificate will be compromised and end up being revoked.

Your .key file is generated during CSR generation and, most probably, it's somewhere on your PC where you generated the CSR.

That's why private key is called "Private" - because nobody can have that file except you.

There are four options here:

1. Get virtualenv set up. Each virtual environment you create will automatically have pip.

2. Get pip set up globally.

3. Learn how to install Python packages manually—in most cases it's as simple as download, unzip, python setup.py install, but not always.

4. Use Christoph Gohlke's binary installers.

There's a facility to have a separate style sheet for print, using

 <link type="text/css" rel="stylesheet" media="print" href="print.css">

I don't know if it does what you want though.

This is very simple you are trying to convert an integer to a list object !!! of course it will fail and it should ...

<class 'int'>
>>>

<class 'int'>
>>>

About System.gc()… I just read in Oracle's documentation the following sentence here

The performance effect of explicit garbage collections can be measured by disabling them using the flag -XX:+DisableExplicitGC, which causes the VM to ignore calls to System.gc().

If your VM vendor and version supports that flag you can run your code with and without it and compare Performance.

Also note the previous quoted sentence is preceded by this one:

This can force a major collection to be done when it may not be necessary (for example, when a minor collection would suffice), and so in general should be avoided.

I guess

List<T> CreateEmptyGenericList<T>(T example) {
    return new List<T>();
}

void something() {
    var o = new { Id = 1, Name = "foo" };
    var emptyListOfAnonymousType = CreateEmptyGenericList(o);
}

will work.

You might also consider writing it like this:

void something() {
    var String = string.Emtpy;
    var Integer = int.MinValue;
    var emptyListOfAnonymousType = CreateEmptyGenericList(new { Id = Integer, Name = String });
}

It's really a 6 of one, a half-dozen of the other situation.

The only possible argument against your approach is $_SERVER['REQUEST_METHOD'] == 'POST' may not be populated on certain web-servers/configuration, whereas the $_POST array will always exist in PHP4/PHP5 (and if it doesn't exist, you have bigger problems (-:)

I found this page which tells you how to import a PFX to JKS (Java Key Store):

For me (selectionChange) and the suggested (onSelectionChange) didn't work and I'm not using ReactiveForms. What I ended up doing was using the (valueChange) event like:

<mat-select (valueChange)="someFunction()">

And this worked for me

The most frequent cause of "no debugging symbols found" when -g is present is that there is some "stray" -s or -S argument somewhere on the link line.

From man ld:

   -s
   --strip-all
       Omit all symbol information from the output file.

   -S
   --strip-debug
       Omit debugger symbol information (but not all symbols) from the output file.

Try:

$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap

This is because Keypress event is fired before the new character is added. Use 'keyup' event instead,which will work perfectly in your situation.

$(document).ready(function() {
    $("#dSuggest").keyup(function() {
        var dInput = $('input:text[name=dSuggest]').val();
        console.log(dInput);
        $(".dDimension:contains('" + dInput + "')").css("display","block");
    });
});

I want to add to this, if you have many textboxes and you have to do the same thing on their keyup event you can simply give them a common css class(eg commoncss) and apply keyup event like this.

$(document).ready(function() {
    $(".commoncss").keyup(function() {
        //your code
    });
});

this will greatly reduce you code as you don't have to apply keyup event by id for each textboxes.

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

import { HttpClient } from '@angular/common/http';

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

...
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

To put it simply: compute engine gives you a server which you have full control/responsibility for. You have direct access to the operating system, and you install all the software that you want, which is usually a web server, database, etc...

In app engine you don't manage the operating system of any of the underlying software. You only upload code (Java, PHP, Python, or Go) and voila - it just runs...

App engine saves tons of headache, especially for inexperienced people but it has 2 significant drawbacks: 1. more expensive (but it does have a free quota which compute engine doesn't) 2. you have less control, thus certain things are just not possible, or only possible in one specific way (for example saving and writing files).

Officially, ConstraintLayout is much faster

In the N release of Android, the ConstraintLayout class provides similar functionality to RelativeLayout, but at a significantly lower cost.

To "fix" an old commit with a small change, without changing the commit message of the old commit, where OLDCOMMIT is something like 091b73a:

git add <my fixed files>
git commit --fixup=OLDCOMMIT
git rebase --interactive --autosquash OLDCOMMIT^

You can also use git commit --squash=OLDCOMMIT to edit the old commit message during rebase.

See documentation for git commit and git rebase. As always, when rewriting git history, you should only fixup or squash commits you have not yet published to anyone else (including random internet users and build servers).

Detailed explanation

• git commit --fixup=OLDCOMMIT copies the OLDCOMMIT commit message and automatically prefixes fixup! so it can be put in the correct order during interactive rebase. (--squash=OLDCOMMIT does the same but prefixes squash!.)
• git rebase --interactive will bring up a text editor (which can be configured) to confirm (or edit) the rebase instruction sequence. There is info for rebase instruction changes in the file; just save and quit the editor (:wq in vim) to continue with the rebase.
• --autosquash will automatically put any --fixup=OLDCOMMIT commits in the correct order. Note that --autosquash is only valid when the --interactive option is used.
• The ^ in OLDCOMMIT^ means it's a reference to the commit just before OLDCOMMIT. (OLDCOMMIT^ is the first parent of OLDCOMMIT.)

Optional automation

The above steps are good for verification and/or modifying the rebase instruction sequence, but it's also possible to skip/automate the interactive rebase text editor by:

• Setting GIT_SEQUENCE_EDITOR to a script.
• Creating a git alias to automatically autosquash all queued fixups.
• Creating a git alias to automatically fixup a single commit.

var textValue = $("input[type=text]").val()

this will get all values of all text boxes. You can use methods like children, firstchild, etc to hone in. Like by form $('form[name=form1] input[type=text]') Easier to use IDs for targeting elements but if it's purely dynamic you can get all input values then loop through then with JS.

Following code worked for me:

public function jsonSerialize()
{
    return get_object_vars($this);
}

Can you not use AcceptButton in for the Forms Properties Window? This sets the default behaviour for the Enter key press, but you are still able to use other shortcuts.

Since Python 3.5 (PEP 448 -- Additional Unpacking Generalizations) one can use the following literal syntax to convert a tuple to a list:

>>> t = (1,2,3)
>>> lst = [*t]
>>> lst
[1, 2, 3]
>>> *lst,  # back to tuple
(1, 2, 3)

A list comprehension can be use to convert a tuple of tuples to a list of lists:

>>> level1 = (
...      (1,1,1,1,1,1),
...      (1,0,0,0,0,1),
...      (1,0,0,0,0,1),
...      (1,0,0,0,0,1),
...      (1,0,0,0,0,1),
...      (1,1,1,1,1,1))
>>> level1_list = [[*row] for row in level1]
>>> level1_list
[[1, 1, 1, 1, 1, 1], 
 [1, 0, 0, 0, 0, 1], 
 [1, 0, 0, 0, 0, 1], 
 [1, 0, 0, 0, 0, 1], 
 [1, 0, 0, 0, 0, 1], 
 [1, 1, 1, 1, 1, 1]]
>>> *((*row,) for row in level1_list),
((1, 1, 1, 1, 1, 1), 
 (1, 0, 0, 0, 0, 1), 
 (1, 0, 0, 0, 0, 1), 
 (1, 0, 0, 0, 0, 1), 
 (1, 0, 0, 0, 0, 1), 
 (1, 1, 1, 1, 1, 1))
>>> _ == level1
True

You can use a defaultdict for this.

from collections import defaultdict
d = defaultdict(list)
d['key'].append('mykey')

This is slightly more efficient than setdefault since you don't end up creating new lists that you don't end up using. Every call to setdefault is going to create a new list, even if the item already exists in the dictionary.

    string strMytestString("hello world");
    cout << strMytestString;
    return 0;
}

stdafx.h isn't pertinent to the solution, everything else is.

Here is a theoretical answer. That can be found here

A { get set } property cannot be a constant stored property. It should be a computed property and both get and set should be implemented.

It's an array, so you're looking for Count to test for contents.

I'd recommend

$foo.count -gt 0

The "why" of this is related to how PSH handles comparison of collection objects

You should be able to do something along the lines of the following

UPDATE s
SET
    OrgAddress1 = bd.OrgAddress1,
    OrgAddress2 = bd.OrgAddress2,
    ...
    DestZip = bd.DestZip
FROM
    Shipment s, ProfilerTest.dbo.BookingDetails bd
WHERE
    bd.MyID = @MyId AND s.MyID2 = @MyID2

FROM statement can be made more optimial (using more specific joins), but the above should do the trick. Also, a nice side benefit to writing it this way, to see a preview of the UPDATE change UPDATE s SET to read SELECT! You will then see that data as it would appear if the update had taken place.

Why not just use atoi? For example:

char myarray[4] = {'-','1','2','3'};

int i = atoi(myarray);

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

Gives me, as expected:

-123

Update: why not - the character array is not null terminated. Doh!

Even more minimal example (draws "Hello world!" in black and with the default font in the top-left of the image):

...
from PIL import ImageDraw
...
ImageDraw.Draw(
    image  # Image
).text(
    (0, 0),  # Coordinates
    'Hello world!',  # Text
    (0, 0, 0)  # Color
)

I used a technique like this before. I use it for the connector list on http://mybackupbox.com

// clone element1 and put the clone before element2
$('element1').clone().before('element2').end();

// replace the original element1 with element2
// leaving the element1 clone in it's place
$('element1').replaceWith('element2');

@outis's answer is good: concise and correct as regards relations.

However, the situation is slightly more complicated as regards SQL.

Consider the usual suppliers and parts database but implemented in SQL:

SELECT * FROM S NATURAL JOIN SP;

would return a resultset** with columns

SNO, SNAME, STATUS, CITY, PNO, QTY

The join is performed on the column with the same name in both tables, SNO. Note that the resultset has six columns and only contains one column for SNO.

Now consider a theta eqijoin, where the column names for the join must be explicitly specified (plus range variables S and SP are required):

SELECT * FROM S JOIN SP ON S.SNO = SP.SNO;

The resultset will have seven columns, including two columns for SNO. The names of the resultset are what the SQL Standard refers to as "implementation dependent" but could look like this:

SNO, SNAME, STATUS, CITY, SNO, PNO, QTY

or perhaps this

S.SNO, SNAME, STATUS, CITY, SP.SNO, PNO, QTY

In other words, NATURAL JOIN in SQL can be considered to remove columns with duplicated names from the resultset (but alas will not remove duplicate rows - you must remember to change SELECT to SELECT DISTINCT yourself).

** I don't quite know what the result of SELECT * FROM table_expression; is. I know it is not a relation because, among other reasons, it can have columns with duplicate names or a column with no name. I know it is not a set because, among other reasons, the column order is significant. It's not even a SQL table or SQL table expression. I call it a resultset.

In C, there's not much difference when used in the startup function of the program (which can be main(), wmain(), _tmain() or the default name used by your compiler).

If you return in main(), control goes back to the _start() function in the C library which originally started your program, which then calls exit() anyways. So it really doesn't matter which one you use.

I've just run in a similar issue. git diff file showed nothing because I added file to the Git index with some part of its name in uppercase: GeoJSONContainer.js.

Afterwards, I've renamed it to GeoJsonContainer.js and changes stopped being tracked. git diff GeoJsonContainer.js was showing nothing. I had to remove the file from the index with a force flag, and add the file again:

git rm -f GeoJSONContainer.js
git add GeoJSONContainer.js

Nice solutions, but I wonder why nobody is giving the solution for windows.

If you are using windows you just have to "Run as Administrator" the cmd.

i used the code below, it solves my problem to add event in default device calendar in ICS and also on version less that ICS

    if (Build.VERSION.SDK_INT >= 14) {
        Intent intent = new Intent(Intent.ACTION_INSERT)
        .setData(Events.CONTENT_URI)
        .putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, beginTime.getTimeInMillis())
        .putExtra(CalendarContract.EXTRA_EVENT_END_TIME, endTime.getTimeInMillis())
        .putExtra(Events.TITLE, "Yoga")
        .putExtra(Events.DESCRIPTION, "Group class")
        .putExtra(Events.EVENT_LOCATION, "The gym")
        .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY)
        .putExtra(Intent.EXTRA_EMAIL, "[email protected],[email protected]");
         startActivity(intent);
}

    else {
        Calendar cal = Calendar.getInstance();              
        Intent intent = new Intent(Intent.ACTION_EDIT);
        intent.setType("vnd.android.cursor.item/event");
        intent.putExtra("beginTime", cal.getTimeInMillis());
        intent.putExtra("allDay", true);
        intent.putExtra("rrule", "FREQ=YEARLY");
        intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
        intent.putExtra("title", "A Test Event from android app");
        startActivity(intent);
        }

Hope it would help.....

I've been having an issue with a CSS3 gradient with -45deg. The background slanted, was badly jagged similar to but worse than the original post. So I started playing with both the background-size. This would stretch out the jaggedness, but it was still there. Then in addition I read that other people are having issues too at 45deg increments so I adjusted from -45deg to -45.0001deg and my problem was solved.

In my CSS below, background-size was initially 30px and the deg for the background gradient was exactly -45deg, and all keyframes were 30px 0.

There are two ways to connect remote redis server using redis-cli:

1. Using host & port individually as options in command

redis-cli -h host -p port

If your instance is password protected

redis-cli -h host -p port -a password

e.g. if my-web.cache.amazonaws.com is the host url and 6379 is the port

Then this will be the command:

redis-cli -h my-web.cache.amazonaws.com -p 6379

if 92.101.91.8 is the host IP address and 6379 is the port:

redis-cli -h 92.101.91.8 -p 6379

command if the instance is protected with password pass123:

redis-cli -h my-web.cache.amazonaws.com -p 6379 -a pass123

2. Using single uri option in command

redis-cli -u redis://password@host:port

command in a single uri form with username & password

redis-cli -u redis://username:password@host:port

e.g. for the same above host - port configuration command would be

redis-cli -u redis://[email protected]:6379

command if username is also provided user123

redis-cli -u redis://user123:[email protected]:6379

This detailed answer was for those who wants to check all options. For more information check documentation: Redis command line usage

Create an XML file named border.xml in the drawable folder and put the following code in it.

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list> 

Then add a background to your linear layout like this:

         android:background="@drawable/border"

EDIT :

This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:

ALSO

tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :

Finally its works perfectly with all APIs

EDIT 2 :

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:left="0dp" android:right="0dp"  android:top="0dp"  
        android:bottom="-10dp"> 
    <shape android:shape="rectangle">
     <stroke android:width="10dp" android:color="#B22222" />
    </shape>
   </item>  
 </layer-list> 

hope this help .

The accepted answer doesn't create a name-only attribute anymore (as of September 2017).

You should use JQuery prop() method to create name-only attributes.

$(body).prop('data-body', true)

Yes, you can!))

Disclaimer: This is not a solution, it is more of a hack to test out something. User-defined functions cannot be used to perform actions that modify the database state.

I found one way to make INSERT, UPDATE or DELETE in function using xp_cmdshell.

So you need just to replace the code inside @sql variable.

CREATE FUNCTION [dbo].[_tmp_func](@orderID NVARCHAR(50))
RETURNS INT
AS
BEGIN
DECLARE @sql varchar(4000), @cmd varchar(4000)
SELECT @sql = 'INSERT INTO _ord (ord_Code) VALUES (''' + @orderID + ''') '
SELECT @cmd = 'sqlcmd -S ' + @@servername +
              ' -d ' + db_name() + ' -Q "' + @sql + '"'
EXEC master..xp_cmdshell @cmd, 'no_output'
RETURN 1
END

Safer way:

a="AAAAAAAAAAAA"
b="BBBBBBBBBBBB"
c="CCCCCCCCCCCC"
d="DD DD"
s="${a}${b}${c}${d}"
echo "$s"
AAAAAAAAAAAABBBBBBBBBBBBCCCCCCCCCCCCDD DD

Strings containing spaces can become part of command, use "$XXX" and "${XXX}" to avoid these errors.

Plus take a look at other answer about +=

The github help link helped me sort out this problem. Looks like the ssh key was not added to the ssh-agent. This is what I ended up doing.

Command 1:

Ensure ssh-agent is enabled. The command starts the ssh-agent in the background:

eval "$(ssh-agent -s)"

Command 2:

Add your SSH key to the ssh-agent:

ssh-add ~/.ssh/id_rsa

I had the same issue: console messages were not appearing in XCode's debug area. In my app I did cmd-d to bring up the debug menu, and remembered I had set "Debug in Safari" on.

I turned this off, and some messages were printed to the output message, but not my console messages. However, one of the log messages said:

__DEV__ === false, development-level warning are OFF, performance optimizations are ON"

This was because I had previously bundled my project for testing on a real device with the command:

react-native bundle --minify

This bundled without "dev-mode" on. To allow dev messages,include the --dev flag:

react-native bundle --dev

And console.log messages are back! If you aren't bundling for a real device, don't forget to re-point jsCodeLocation in AppDelegate.m to localhost (I did!).

To temporarily work around this problem, I found the following to be the quickest way:

export JAVA_TOOL_OPTIONS="-Xmx1024m -Xms1024m"

Initially go to your home and press Ctrl + H it will show you hidden files now look for .bashrc file, open it with any text editor then place below lines at the end of file.

export ANDROID_HOME=/home/varun/Android/Sdk
export PATH=$PATH:/home/varun/Android/Sdk/tools
export PATH=$PATH:/home/varun/Android/Sdk/platform-tools

Please change /home/varun/Android/Sdk path to your SDK path. Do the same for tools and platform-tools.

After this save .bashrc file and close it.

Now you are ready to use ADB commands on terminal.

Don’t Repeat Your CSS

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

OR

 a{
    margin-left:20px;
 }

<h:button>

The <h:button> generates a HTML <input type="button">. The generated element uses JavaScript to navigate to the page given by the attribute outcome, using a HTTP GET request.

E.g.

<h:button value="GET button" outcome="otherpage" />

will generate

<input type="button" onclick="window.location.href='/contextpath/otherpage.xhtml'; return false;" value="GET button" />

Even though this ends up in a (bookmarkable) URL change in the browser address bar, this is not SEO-friendly. Searchbots won't follow the URL in the onclick. You'd better use a <h:outputLink> or <h:link> if SEO is important on the given URL. You could if necessary throw in some CSS on the generated HTML <a> element to make it to look like a button.

Do note that while you can put an EL expression referring a method in outcome attribute as below,

<h:button value="GET button" outcome="#{bean.getOutcome()}" />

it will not be invoked when you click the button. Instead, it is already invoked when the page containing the button is rendered for the sole purpose to obtain the navigation outcome to be embedded in the generated onclick code. If you ever attempted to use the action method syntax as in outcome="#{bean.action}", you would already be hinted by this mistake/misconception by facing a javax.el.ELException: Could not find property actionMethod in class com.example.Bean.

If you intend to invoke a method as result of a POST request, use <h:commandButton> instead, see below. Or if you intend to invoke a method as result of a GET request, head to Invoke JSF managed bean action on page load or if you also have GET request parameters via <f:param>, How do I process GET query string URL parameters in backing bean on page load?

<h:commandButton>

The <h:commandButton> generates a HTML <input type="submit"> button which submits by default the parent <h:form> using HTTP POST method and invokes the actions attached to action, actionListener and/or <f:ajax listener>, if any. The <h:form> is required.

E.g.

<h:form id="form">
    <h:commandButton id="button" value="POST button" action="otherpage" />
</h:form>

will generate

<form id="form" name="form" method="post" action="/contextpath/currentpage.xhtml" enctype="application/x-www-form-urlencoded">
    <input type="hidden" name="form" value="form" />
    <input type="submit" name="form:button" value="POST button" />
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="...." autocomplete="off" />
</form>

Note that it thus submits to the current page (the form action URL will show up in the browser address bar). It will afterwards forward to the target page, without any change in the URL in the browser address bar. You could add ?faces-redirect=true parameter to the outcome value to trigger a redirect after POST (as per the Post-Redirect-Get pattern) so that the target URL becomes bookmarkable.

The <h:commandButton> is usually exclusively used to submit a POST form, not to perform page-to-page navigation. Normally, the action points to some business action, such as saving the form data in DB, which returns a String outcome.

<h:commandButton ... action="#{bean.save}" />

with

public String save() {
    // ...
    return "otherpage";
}

Returning null or void will bring you back to the same view. Returning an empty string also, but it would recreate any view scoped bean. These days, with modern JSF2 and <f:ajax>, more than often actions just return to the same view (thus, null or void) wherein the results are conditionally rendered by ajax.

public void save() {
    // ...
}

A lot of people have mention that "objects cannot be sorted", but after that they are giving you a solution which works. Paradox, isn't it?

No one mention why those solutions are working. They are, because in most of the browser's implementations values in objects are stored in the order in which they were added. That's why if you create new object from sorted list of keys it's returning an expected result.

And I think that we could add one more solution – ES5 functional way:

function sortObject(obj) {
    return Object.keys(obj).sort().reduce(function (result, key) {
        result[key] = obj[key];
        return result;
    }, {});
}

ES2015 version of above (formatted to "one-liner"):

const sortObject = o => Object.keys(o).sort().reduce((r, k) => (r[k] = o[k], r), {})

Short explanation of above examples (as asked in comments):

Object.keys is giving us a list of keys in provided object (obj or o), then we're sorting those using default sorting algorithm, next .reduce is used to convert that array back into an object, but this time with all of the keys sorted.

You may use Map.entrySet() method:

for (Map.Entry entry : objectSet.entrySet())
{
    System.out.println("key: " + entry.getKey() + "; value: " + entry.getValue());
}

You can simply concatnate two lists, e.g:

list1 = [0, 1]
list2 = [2, 3]
list3 = list1 + list2

print(list3)
>> [0, 1, 2, 3]

a reply to @DarinDimitrov for a case where i have used foreach in a razor view.

<li><label for="category">Category</label>
        <select id="category">
            <option value="0">All</option>
            @foreach(Category c in Model.Categories)
            {
                <option title="@c.Description" value="@c.CategoryID">@c.Name</option>
            }
        </select>
</li>

You can try this incase you would like to match parent. The dimensions arrangement is width and height inorder

web = new WebView(this);
        web.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

You want GetAbbreviatedMonthName

a piece of code who work with python to read rs232 just in case somedoby else need it

ser = serial.Serial('/dev/tty.usbserial', 9600, timeout=0.5)
ser.write('*99C\r\n')
time.sleep(0.1)
ser.close()

I've been mislead by this error more than once. After spending hours googling, updating nuget packages, version checking, then after sitting with a completely updated solution I re-realize a perfectly valid, simpler reason for the error.

If in a threaded enthronement (UI Dispatcher.Invoke for example), System.IO.FileNotFoundException is thrown if the thread manager dll (file) fails to return. So if your main UI thread A, calls the system thread manager dll B, and B calls your thread code C, but C throws for some unrelated reason (such as null Reference as in my case), then C does not return, B does not return, and A only blames B with FileNotFoundException for being lost...

Before going down the dll version path... Check closer to home and verify your thread code is not throwing.

Make sure you plug the Arduino directly into the computer and not through a hub. Using a hub will give you this error.

To support IE11 with auto-placement, I converted grid to table layout every time I used the grid layout in 1 dimension only. I also used margin instead of grid-gap.

Never mind got the way to do it.

It's actually fairly easy, just enter it as a latitude,longitude pair, ie 46.38S,115.36E (which is in the middle of the ocean). You'll want to convert it to decimal though (divide the minutes portion by 60 and add it to the degrees [I've done that with your example]).

I use the CONCATENATE method to take the values of a column and wrap quotes around them with columns in between in order to quickly populate the WHERE IN () clause of a SQL statement.

I always just type =CONCATENATE("'",B2,"'",",") and then select that and drag it down, which creates =CONCATENATE("'",B3,"'",","), =CONCATENATE("'",B4,"'",","), etc. then highlight that whole column, copy paste to a plain text editor and paste back if needed, thus stripping the row separation. It works, but again, just as a one time deal, this is not a good solution for someone who needs this all the time.

We have found Jsmooth to be well-working and easily scriptable with ant under Linux. You may want to use one-jar (also easily scriptable with ant under Linux) to collect a multifile application in a single jar first.

We primarily needed the easy deployment of the EXE combined with the "hey, you need Java version X, go here to download" facilities.

(but what you most likely need is the "Runnable jar" / "Executable jar" facility in standard Java).

If you want to add SSL in your test environment, then you can use mkcert. Below I mentioned the GitHub URL.

And also below I mentioned sample nginx configuration for reverse proxy.

server {
        listen 80;
        server_name test.local;
        return 301 https://test.local$request_uri;
}
server {
  listen 443 ssl;
  server_name test.local;
  ssl_certificate /etc/nginx/ssl/test.local.pem;
  ssl_certificate_key /etc/nginx/ssl/test.local-key.pem;

   location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $remote_addr;
      proxy_set_header X-Client-Verify SUCCESS;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      proxy_pass http://localhost:3000;
      proxy_redirect off;
      proxy_buffering off;
    }
}

for ($s=65; $s<=90; $s++) {
    //echo chr($s);
    $objPHPExcel->getActiveSheet()->getColumnDimension(chr($s))->setAutoSize(true);
}

If you know the height, you can use absolute positioning with a negative margin-top like so:

#Login {
    width:400px;
    height:400px;
    position:absolute;
    top:50%;
    left:50%;
    margin-left:-200px; /* width / -2 */
    margin-top:-200px; /* height / -2 */
}

Otherwise, there's no real way to vertically center a div with just CSS

I shared my experience of using two LEFT JOINS in a single SQL query.

I have 3 tables:

Table 1) Patient consists columns PatientID, PatientName

Table 2) Appointment consists columns AppointmentID, AppointmentDateTime, PatientID, DoctorID

Table 3) Doctor consists columns DoctorID, DoctorName

Query:

SELECT Patient.patientname, AppointmentDateTime, Doctor.doctorname

FROM Appointment 

LEFT JOIN Doctor ON Appointment.doctorid = Doctor.doctorId  //have doctorId column common

LEFT JOIN Patient ON Appointment.PatientId = Patient.PatientId      //have patientid column common

WHERE Doctor.Doctorname LIKE 'varun%' // setting doctor name by using LIKE

AND Appointment.AppointmentDateTime BETWEEN '1/16/2001' AND '9/9/2014' //comparison b/w dates 

ORDER BY AppointmentDateTime ASC;  // getting data as ascending order

I wrote the solution to get date format like "mm/dd/yy" (under my name "VARUN TEJ REDDY")

You can also do it like this:

var tt="88,9827";
tt=tt.replace(",", ".");
alert(tt);

Here is a little refactoring of your function (it does not use "else" or "elif"):

def function(a):
    if a not in (1, 2):
        a = 3
    print(str(a) + "a")

@ghostdog74: Python 3 requires parentheses for "print".

I wrote a little class that is doing what you want, you can test it here.

Only thing that is different from your proposal is that I don't consider

[1,[{c: 1},2,3],{a:'hey'}]

and

[{a:'hey'},1,[3,{c: 1},2]]

to be same, because I think that arrays are not equal if order of their elements is not same. Of course this can be changed if needed. Also this code can be further enhanced to take function as argument that will be used to format diff object in arbitrary way based on passed primitive values (now this job is done by "compareValues" method).

var deepDiffMapper = function () {
  return {
    VALUE_CREATED: 'created',
    VALUE_UPDATED: 'updated',
    VALUE_DELETED: 'deleted',
    VALUE_UNCHANGED: 'unchanged',
    map: function(obj1, obj2) {
      if (this.isFunction(obj1) || this.isFunction(obj2)) {
        throw 'Invalid argument. Function given, object expected.';
      }
      if (this.isValue(obj1) || this.isValue(obj2)) {
        return {
          type: this.compareValues(obj1, obj2),
          data: obj1 === undefined ? obj2 : obj1
        };
      }

      var diff = {};
      for (var key in obj1) {
        if (this.isFunction(obj1[key])) {
          continue;
        }

        var value2 = undefined;
        if (obj2[key] !== undefined) {
          value2 = obj2[key];
        }

        diff[key] = this.map(obj1[key], value2);
      }
      for (var key in obj2) {
        if (this.isFunction(obj2[key]) || diff[key] !== undefined) {
          continue;
        }

        diff[key] = this.map(undefined, obj2[key]);
      }

      return diff;

    },
    compareValues: function (value1, value2) {
      if (value1 === value2) {
        return this.VALUE_UNCHANGED;
      }
      if (this.isDate(value1) && this.isDate(value2) && value1.getTime() === value2.getTime()) {
        return this.VALUE_UNCHANGED;
      }
      if (value1 === undefined) {
        return this.VALUE_CREATED;
      }
      if (value2 === undefined) {
        return this.VALUE_DELETED;
      }
      return this.VALUE_UPDATED;
    },
    isFunction: function (x) {
      return Object.prototype.toString.call(x) === '[object Function]';
    },
    isArray: function (x) {
      return Object.prototype.toString.call(x) === '[object Array]';
    },
    isDate: function (x) {
      return Object.prototype.toString.call(x) === '[object Date]';
    },
    isObject: function (x) {
      return Object.prototype.toString.call(x) === '[object Object]';
    },
    isValue: function (x) {
      return !this.isObject(x) && !this.isArray(x);
    }
  }
}();


var result = deepDiffMapper.map({
  a: 'i am unchanged',
  b: 'i am deleted',
  e: {
    a: 1,
    b: false,
    c: null
  },
  f: [1, {
    a: 'same',
    b: [{
      a: 'same'
    }, {
      d: 'delete'
    }]
  }],
  g: new Date('2017.11.25')
}, {
  a: 'i am unchanged',
  c: 'i am created',
  e: {
    a: '1',
    b: '',
    d: 'created'
  },
  f: [{
    a: 'same',
    b: [{
      a: 'same'
    }, {
      c: 'create'
    }]
  }, 1],
  g: new Date('2017.11.25')
});
console.log(result);

A really good simple ORM is MyActiveRecord. MyActiveRecord documentation. I have been using it a lot and can say it's very simple and well tested.

Since it looks like that you only need this structure for the update() function, don't use a structure for this at all, it will only obfuscate your intention behind that construct. You should maybe rethink why you are changing and updating those fields and define separate functions or macros for this "little" changes.

e.g.

#define set_current_route(id, route) update(id, dont_care, dont_care, route)
#define set_route(id, route) update(id, dont_care, route, dont_care)
#define set_backup_route(id, route) update(id, route, dont_care, dont_care)

Or even better write a function for every change case. As you already noticed you don't change every property at the same time, so make it possible to change only one property at a time. This doesn't only improve the readability, but also helps you handling the different cases, e.g. you don't have to check for all the "dont_care" because you know that only the current route is changed.

please consider .editorconfig overwrites everything, use:

1. 12.25d is your float.
2. You write 12d in binary and remove it from your float. Only the remainder (.25d) will be left.
3. You write the dot.
4. While the remainder (0.25d) is not zero (and/or you want more digits), multiply it with 2 (-> 0.50d), remove and write the digit left of the dot (0), and continue with the new remainder (.50d).

Forking creates an entirely new repository from existing repository (simply doing git clone on gitHub/bitbucket)

Forks are best used: when the intent of the ‘split’ is to create a logically independent project, which may never reunite with its parent.

Branch strategy creates a new branch over the existing/working repository

Branches are best used: when they are created as temporary places to work through a feature, with the intent to merge the branch with the origin.

More Specific :- In open source projects it is the owner of the repository who decides who can push to the repository. However, the idea of open source is that everybody can contribute to the project.

This problem is solved by forks: any time a developer wants to change something in an open source project, they don’t clone the official repository directly. Instead, they fork it to create a copy. When the work is finished, they make a pull request so that the owner of the repository can review the changes and decide whether to merge them to his project.

At its core forking is similar to feature branching, but instead of creating branches a fork of the repository is made, and instead of doing a merge request you create a pull request.

The below links provide the difference in a well-explained manner :

I've used a NSDictionary as datasource, this looks like a lot of code, but it's really simple and works very well! how looks here

I created a enum for the sections

typedef NS_ENUM(NSUInteger, TableViewSection) {

    TableViewSection0 = 0,
    TableViewSection1,
    TableViewSection2,
    TableViewSectionCount
};

sections property:

@property (nonatomic, strong) NSMutableDictionary * sectionsDisctionary;

A method returning my sections:

-(NSArray <NSNumber *> * )sections{

    return @[@(TableViewSection0), @(TableViewSection1), @(TableViewSection2)];
}

And then setup my data soruce:

-(void)loadAndSetupData{

    self.sectionsDisctionary = [NSMutableDictionary dictionary];

    NSArray * sections = [self sections];

    for (NSNumber * section in sections) {

    NSArray * sectionObjects = [self objectsForSection:section.integerValue];

    [self.sectionsDisctionary setObject:[NSMutableDictionary dictionaryWithDictionary:@{@"visible" : @YES, @"objects" : sectionObjects}] forKey:section];
    }
}

-(NSArray *)objectsForSection:(NSInteger)section{

    NSArray * objects;

    switch (section) {

        case TableViewSection0:

            objects = @[] // objects for section 0;
            break;

        case TableViewSection1:

            objects = @[] // objects for section 1;
            break;

        case TableViewSection2:

            objects = @[] // objects for section 2;
            break;

        default:
            break;
    }

    return objects;
}

Looks like the NoCoffee Vision Simulator extension for Chrome will also cause this error. Just adding it as a prospective cause for people looking in their own instance.

For me the same exception was thrown when the toString was defined as such:

@Override
public String toString() {
    return "ListElem [next=" + next + ", data=" + data + "]";
}

Where ListElem is a linked list element and I created a ListElem as such:

private ListElem<Integer> cyclicLinkedList = new ListElem<>(3);
ListElem<Integer> cyclicObj = new ListElem<>(4);
...

cyclicLinkedList.setNext(new ListElem<Integer>(2)).setNext(cyclicObj)
    .setNext(new ListElem<Integer>(6)).setNext(new ListElem<Integer>(2)).setNext(cyclicObj);

This effectively caused a cyclic linked list that cannot be printed. Thanks for the pointer.

removeprefix() and removesuffix() string methods added in Python 3.9 due to issues associated with lstrip and rstrip interpretation of parameters passed to them. Read PEP 616 for more details.

# in python 3.9
>>> s = 'python_390a6'

# apply removeprefix()
>>> s.removeprefix('python_')
'390a6'

# apply removesuffix()
>>> s = 'python.exe'
>>> s.removesuffix('.exe')
'python'

# in python 3.8 or before
>>> s = 'python_390a6'
>>> s.lstrip('python_')
'390a6'

>>> s = 'python.exe'
>>> s.rstrip('.exe')
'python'

removesuffix example with a list:

plurals = ['cars', 'phones', 'stars', 'books']
suffix = 's'

for plural in plurals:
    print(plural.removesuffix(suffix))

output:

car
phone
star
book

removeprefix example with a list:

places = ['New York', 'New Zealand', 'New Delhi', 'New Now']

shortened = [place.removeprefix('New ') for place in places]
print(shortened)

output:

['York', 'Zealand', 'Delhi', 'Now']

It depends. You could

string.match(/^abc$/)

But that would not match the following string: 'the first 3 letters of the alphabet are abc. not abc123'

I think you would want to use \b (word boundaries):

var str = 'the first 3 letters of the alphabet are abc. not abc123';_x000D_
var pat = /\b(abc)\b/g;_x000D_
console.log(str.match(pat));

Live example: http://jsfiddle.net/uu5VJ/

If the former solution works for you, I would advise against using it.

That means you may have something like the following:

var strs = ['abc', 'abc1', 'abc2']
for (var i = 0; i < strs.length; i++) {
    if (strs[i] == 'abc') {
        //do something 
    }
    else {
        //do something else
    }
}

While you could use

if (str[i].match(/^abc$/g)) {
    //do something 
}

It would be considerably more resource-intensive. For me, a general rule of thumb is for a simple string comparison use a conditional expression, for a more dynamic pattern use a regular expression.

window.location sets the URL of your current window. To open a new window, you need to use window.open. This should work:

function ToKey(){
    var key = document.tokey.key.value.toLowerCase();
    if (key == "smk") {
        window.open('http://www.smkproduction.eu5.org', '_blank');
    } else {
        alert("Kodi nuk është valid!");
    }
}

This is what worked for me...

#Did manipulations for my project where my array values went way over 255
#Eventually returned numbers to between 0 and 255

#Converted the datatype to np.uint8
new_image = new_image.astype(np.uint8)

#Separated the channels in my new image
new_image_red, new_image_green, new_image_blue = new_image

#Stacked the channels
new_rgb = np.dstack([new_image_red, new_image_green, new_image_blue])

#Displayed the image
cv2.imshow("WindowNameHere", new_rgbrgb)

You can use Request.Url.AbsolutePath to get the page name, and Request.Url.Authority for the host name and port. I don't believe there is a built in property to give you exactly what you want, but you can combine them yourself.

You could use the pickle module in the standard library. Here's an elementary application of it to your example:

import pickle

class Company(object):
    def __init__(self, name, value):
        self.name = name
        self.value = value

with open('company_data.pkl', 'wb') as output:
    company1 = Company('banana', 40)
    pickle.dump(company1, output, pickle.HIGHEST_PROTOCOL)

    company2 = Company('spam', 42)
    pickle.dump(company2, output, pickle.HIGHEST_PROTOCOL)

del company1
del company2

with open('company_data.pkl', 'rb') as input:
    company1 = pickle.load(input)
    print(company1.name)  # -> banana
    print(company1.value)  # -> 40

    company2 = pickle.load(input)
    print(company2.name) # -> spam
    print(company2.value)  # -> 42

You could also define your own simple utility like the following which opens a file and writes a single object to it:

def save_object(obj, filename):
    with open(filename, 'wb') as output:  # Overwrites any existing file.
        pickle.dump(obj, output, pickle.HIGHEST_PROTOCOL)

# sample usage
save_object(company1, 'company1.pkl')

Update

Since this is such a popular answer, I'd like touch on a few slightly advanced usage topics.

cPickle (or _pickle) vs pickle

It's almost always preferable to actually use the cPickle module rather than pickle because the former is written in C and is much faster. There are some subtle differences between them, but in most situations they're equivalent and the C version will provide greatly superior performance. Switching to it couldn't be easier, just change the import statement to this:

import cPickle as pickle

In Python 3, cPickle was renamed _pickle, but doing this is no longer necessary since the pickle module now does it automatically—see What difference between pickle and _pickle in python 3?.

The rundown is you could use something like the following to ensure that your code will always use the C version when it's available in both Python 2 and 3:

try:
    import cPickle as pickle
except ModuleNotFoundError:
    import pickle

Data stream formats (protocols)

pickle can read and write files in several different, Python-specific, formats, called protocols as described in the documentation, "Protocol version 0" is ASCII and therefore "human-readable". Versions > 0 are binary and the highest one available depends on what version of Python is being used. The default also depends on Python version. In Python 2 the default was Protocol version 0, but in Python 3.8.1, it's Protocol version 4. In Python 3.x the module had a pickle.DEFAULT_PROTOCOL added to it, but that doesn't exist in Python 2.

Fortunately there's shorthand for writing pickle.HIGHEST_PROTOCOL in every call (assuming that's what you want, and you usually do), just use the literal number -1 — similar to referencing the last element of a sequence via a negative index. So, instead of writing:

pickle.dump(obj, output, pickle.HIGHEST_PROTOCOL)

You can just write:

pickle.dump(obj, output, -1)

Either way, you'd only have specify the protocol once if you created a Pickler object for use in multiple pickle operations:

pickler = pickle.Pickler(output, -1)
pickler.dump(obj1)
pickler.dump(obj2)
   etc...

Note: If you're in an environment running different versions of Python, then you'll probably want to explicitly use (i.e. hardcode) a specific protocol number that all of them can read (later versions can generally read files produced by earlier ones).

Multiple Objects

While a pickle file can contain any number of pickled objects, as shown in the above samples, when there's an unknown number of them, it's often easier to store them all in some sort of variably-sized container, like a list, tuple, or dict and write them all to the file in a single call:

tech_companies = [
    Company('Apple', 114.18), Company('Google', 908.60), Company('Microsoft', 69.18)
]
save_object(tech_companies, 'tech_companies.pkl')

and restore the list and everything in it later with:

with open('tech_companies.pkl', 'rb') as input:
    tech_companies = pickle.load(input)

The major advantage is you don't need to know how many object instances are saved in order to load them back later (although doing so without that information is possible, it requires some slightly specialized code). See the answers to the related question Saving and loading multiple objects in pickle file? for details on different ways to do this. Personally I like @Lutz Prechelt's answer the best. Here's it adapted to the examples here:

class Company:
    def __init__(self, name, value):
        self.name = name
        self.value = value

def pickled_items(filename):
    """ Unpickle a file of pickled data. """
    with open(filename, "rb") as f:
        while True:
            try:
                yield pickle.load(f)
            except EOFError:
                break

print('Companies in pickle file:')
for company in pickled_items('company_data.pkl'):
    print('  name: {}, value: {}'.format(company.name, company.value))

Without proper language support for thread syncronization, it doesn't even make sense for new implementations to try. Existing complex JS apps (e.g. anything using ExtJS) would most likely crash unexpectedly, but without a synchronized keyword or something similar, it would also be very hard or even impossible to write new programs that behave correctly.

array1.NonIntersect(array2);

Nonintersect such operator is not present in Linq you should do

except -> union -> except

a.except(b).union(b.Except(a));

UTF-8 and UCS-2/UTF-16 can be distinguished reasonably easily via a byte order mark at the start of the file. If this exists then it's a pretty good bet that the file is in that encoding - but it's not a dead certainty. You may well also find that the file is in one of those encodings, but doesn't have a byte order mark.

I don't know much about ISO-8859-2, but I wouldn't be surprised if almost every file is a valid text file in that encoding. The best you'll be able to do is check it heuristically. Indeed, the Wikipedia page talking about it would suggest that only byte 0x7f is invalid.

There's no idea of reading a file "as it is" and yet getting text out - a file is a sequence of bytes, so you have to apply a character encoding in order to decode those bytes into characters.

In configuration class

@Configuration
@PropertySource("classpath:/com/myco/app.properties")
public class AppConfig {
   @Autowired
   Environment env;

   @Bean
   public TestBean testBean() {
       TestBean testBean = new TestBean();
       testBean.setName(env.getProperty("testbean.name"));
       return testBean;
   }
}

Do it in the code-behind by setting the text color initially to gray and adding event handlers for gaining and losing keyboard focus.

TextBox tb = new TextBox();
tb.Foreground = Brushes.Gray;
tb.Text = "Text";
tb.GotKeyboardFocus += new KeyboardFocusChangedEventHandler(tb_GotKeyboardFocus);
tb.LostKeyboardFocus += new KeyboardFocusChangedEventHandler(tb_LostKeyboardFocus);

Then the event handlers:

private void tb_GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
    if(sender is TextBox)
    {
        //If nothing has been entered yet.
        if(((TextBox)sender).Foreground == Brushes.Gray)
        {
            ((TextBox)sender).Text = "";
            ((TextBox)sender).Foreground = Brushes.Black;
        }
    }
}


private void tb_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
    //Make sure sender is the correct Control.
    if(sender is TextBox)
    {
        //If nothing was entered, reset default text.
        if(((TextBox)sender).Text.Trim().Equals(""))
        {
            ((TextBox)sender).Foreground = Brushes.Gray;
            ((TextBox)sender).Text = "Text";
        }
    }
}

Alternative: Stream.concat()

Stream.concat(map.values().stream(), listContainer.lst.stream())
                             .collect(Collectors.toList()

One more thing - TemplateBindings don't allow value converting. They don't allow you to pass a Converter and don't automatically convert int to string for example (which is normal for a Binding).

Since Hadoop 3.0.0 - Alpha 1 there was a Change in the port configuration:

Try creating a linked server (which you can do with sp_addlinkedserver) and then using OPENQUERY

If you have a for loop such as the one below.

Change @item.StartDate to @item.StartDate.Value.ToShortDateString()

This will remove the time just in case you can't annotate your property in the model like in my case.

<table>
  <tr>
   <th>Type</th>
   <th>Start Date</th>
  </tr>
    @foreach (var item in Model.TestList) {
      <tr>
        <td>@item.TypeName</td>
        <td>@item.StartDate.Value.ToShortDateString()</td>
      </tr>
      }
</table>

Here is the correct way:

import MySQLdb

if __name__ == '__main__':
    connect = MySQLdb.connect(host="localhost", port=3306,
                              user="xxx", passwd="xxx", db='xxx', charset='utf8')

    cursor = connect.cursor()

    cursor.execute("""
       UPDATE tblTableName
       SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
       WHERE Server=%s
    """, (Year, Month, Day, Hour, Minute, ServerID))

    connect.commit()
    connect.close()

P.S. Don't forget connect.commit(), or it won't work

This had no effect for me:

public void changeTheme(int newTheme) {
    setTheme(newTheme);
    recreate();
}

But this worked:

int theme = R.style.default;

protected void onCreate(Bundle savedInstanceState) {
    setTheme(this.theme);
    super.onCreate(savedInstanceState);
}

public void changeTheme(int newTheme) {
    this.theme = newTheme;
    recreate();
}

To add a WHERE clause inside an INSERT statement simply;

INSERT INTO table_name (column1,column2,column3)
SELECT column1, column2, column3 FROM  table_name
WHERE column1 = 'some_value'

For checking existence one can also use (works for both, files and folders):

Not Dir(DirFile, vbDirectory) = vbNullString

_{The result is True if a file or a directory exists.}

Example:

If Not Dir("C:\Temp\test.xlsx", vbDirectory) = vbNullString Then
    MsgBox "exists"
Else
    MsgBox "does not exist"
End If

Works Fine. Try this,

private void addImageButton_Click(object sender, EventArgs e)
{
    OpenFileDialog of = new OpenFileDialog();
    //For any other formats
    of.Filter = "Image Files (*.bmp;*.jpg;*.jpeg,*.png)|*.BMP;*.JPG;*.JPEG;*.PNG"; 
    if (of.ShowDialog() == DialogResult.OK)
    {
        pictureBox1.ImageLocation = of.FileName;

    }
}

You need to calculate UILabel size when you put insets. It can have different number of lines because of text alignment, line break mode.

override func drawText(in rect: CGRect) {

    let size = self.sizeThatFits(UIEdgeInsetsInsetRect(rect, insets).size);
    super.drawText(in: CGRect.init(origin: CGPoint.init(x: insets.left, y: insets.top), size: size));
}

override var intrinsicContentSize: CGSize {

    var size = super.intrinsicContentSize;

    if text == nil || text?.count == 0 {
        return size;
    }

    size = self.sizeThatFits(UIEdgeInsetsInsetRect(CGRect.init(origin: CGPoint.zero, size: size), insets).size);
    size.width  += self.insets.left + self.insets.right;
    size.height += self.insets.top + self.insets.bottom;

    return size;
}

try iEun/InsetLabel

The easiest way i always handle this Where

 $con = mysqli_connect($serverName,$dbusername,$dbpassword);

3 steps replacement in the following order

1. All "mysql_select_db(" with "mysqli_select_db($con,"
2. All "mysql_query(" with "mysqli_query($con," and
3. All "mysql_" with "mysqli_".

This works for me everytime

Python 3.6 gives us f-strings, which are a delight:

var1 = "foo"
var2 = "bar"
var3 = f"{var1}{var2}"
print(var3)                       # prints foobar

You can do most anything inside the curly braces

print(f"1 + 1 == {1 + 1}")        # prints 1 + 1 == 2

static variables are specific to a class . Constructors initialize attributes ESPECIALY for an instance.

I think the secret guru register is the expression = register. It can be used for creative mappings.

:inoremap  \d The current date <c-r>=system("date")<cr>

You can use it in conjunction with your system as above or get responses from custom VimL functions etc.

or just ad hoc stuff like

<c-r>=35+7<cr>

the command to get the effective push remote for the branch, e.g., master, is:

git config branch.master.pushRemote || git config remote.pushDefault || git config branch.master.remote

Here's why (from the "man git config" output):

branch.name.remote [...] tells git fetch and git push which remote to fetch from/push to [...] [for push] may be overridden with remote.pushDefault (for all branches) [and] for the current branch [..] further overridden by branch.name.pushRemote [...]

For some reason, "man git push" only tells about branch.name.remote (even though it has the least precedence of the three) + erroneously states that if it is not set, push defaults to origin - it does not, it's just that when you clone a repo, branch.name.remote is set to origin, but if you remove this setting, git push will fail, even though you still have the origin remote

Before trying anything else in this post, I would do Build >> Clean Project. It solved my problem and it is the simplest solution. Sometimes, the cleaning doesnt get some links, so I also recommend you to restart your devices, either virtual or physical.

If it doesnt work out, try turning of Instant Run by File > Settings > Build,Execution,Deployment > Instant Run > Un-check

Only after trying this two simple solutions, I would try the others.

You could use Linq's Aggregate function:

string s = "the\nquick\tbrown\rdog,jumped;over the lazy fox.";
char[] chars = new char[] { ' ', ';', ',', '\r', '\t', '\n' };
string snew = chars.Aggregate(s, (c1, c2) => c1.Replace(c2, '\n'));

Here's the extension method:

public static string ReplaceAll(this string seed, char[] chars, char replacementCharacter)
{
    return chars.Aggregate(seed, (str, cItem) => str.Replace(cItem, replacementCharacter));
}

Extension method usage example:

string snew = s.ReplaceAll(chars, '\n');

Just putting this here in case it helps someone, my case was different and a bit of an odd mix. I was getting this on a request that was accessed via superagent - the problem had nothing to do with certificates (which were setup properly) and all to do with the fact that I was then passing the superagent result through the async module's waterfall callback. To fix: Instead of passing the entire result, just pass result.body through the waterfall's callback.

Just like Namespace of C# codes.

The simple answer:

• doing a MOV RBX, 3 and MUL RBX is expensive; just ADD RBX, RBX twice

• ADD 1 is probably faster than INC here

• MOV 2 and DIV is very expensive; just shift right

• 64-bit code is usually noticeably slower than 32-bit code and the alignment issues are more complicated; with small programs like this you have to pack them so you are doing parallel computation to have any chance of being faster than 32-bit code

If you generate the assembly listing for your C++ program, you can see how it differs from your assembly.

When you say "by warnings" what exactly do you mean? I've usually seen it giving a hint that you may want to use var, but nothing as harsh as a warning.

There's no performance difference with var - the code is compiled to the same IL. The potential benefit is in readability - if you've already made the type of the variable crystal clear on the RHS of the assignment (e.g. via a cast or a constructor call), where's the benefit of also having it on the LHS? It's a personal preference though.

If you don't want R# suggesting the use of var, just change the options. One thing about ReSharper: it's very configurable :)

Try

//book[title/@lang = 'it']

This reads:

• get all book elements
  • that have at least one title
    • which has an attribute lang
      • with a value of "it"

You may find this helpful — it's an article entitled "XPath in Five Paragraphs" by Ronald Bourret.

But in all honesty, //book[title[@lang='it']] and the above should be equivalent, unless your XPath engine has "issues." So it could be something in the code or sample XML that you're not showing us -- for example, your sample is an XML fragment. Could it be that the root element has a namespace, and you aren't counting for that in your query? And you only told us that it didn't work, but you didn't tell us what results you did get.

I don't know of any way to do this with grep, but it is possible to use awk to achieve the same result:

awk '/blah/ {getline;print}' < logfile

Jersey throws an com.sun.jersey.api.ParamException when it fails to unmarshall the parameters so one solution is to create an ExceptionMapper that handles these types of exceptions:

@Provider
public class ParamExceptionMapper implements ExceptionMapper<ParamException> {
    @Override
    public Response toResponse(ParamException exception) {
        return Response.status(Status.BAD_REQUEST).entity(exception.getParameterName() + " incorrect type").build();
    }
}

Although I agree completely with delnan's answer, it's not impossible:

loop = range(NUM_ITERATIONS+1)
while loop.pop():
    do_stuff()

Note, however, that this will not work for an arbitrary list: If the first value in the list (the last one popped) does not evaluate to False, you will get another iteration and an exception on the next pass: IndexError: pop from empty list. Also, your list (loop) will be empty after the loop.

Just for curiosity's sake. ;)
