Different approaches and different strategies. In my case I could not find the window of my dialog either through using VisualTreeHelper or extension methods from Telerik to find parent of given type. Instead, I found my my dialog view which accepts custom injection of contents using Application.Current.Windows.

public Window GetCurrentWindowOfType<TWindowType>(){
 return Application.Current.Windows.OfType<TWindowType>().FirstOrDefault() as Window;
}

Just putting it in your input field : onkeypress='return event.charCode >= 48 && event.charCode <= 57'

To avoid that issue, when incrementing time you should convert back to UTC and then add or subtract.

This way you will be able to walk through any periods where hours or minutes happen twice.

If you converted to UTC, add each second, and convert to local time for display. You would go through 11:54:08 p.m. LMT - 11:59:59 p.m. LMT and then 11:54:08 p.m. CST - 11:59:59 p.m. CST.

Just use list comprehension.

Half line solution:

common_elements = [x for x in list1 if x in list2]

If that helped, consider upvoting my answer.

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:

struct {                   11
    char a;      012345678901
    short b;     ------------
    char c;      axbbcxxxdddd
    int d;
};

This structure will occupy 12 bytes of memory (x being pad bytes).

Python works similarly (see the struct documentation):

>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12

Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:

>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'

Beware of letting struct handle padding. In C, these structures:

struct A {       struct B {
    short a;         int a;
    char b;          char b;
};               };

are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:

>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'

Here's a solution similar to the currently accepted answer (https://stackoverflow.com/a/925630/95989), except that it uses the internal HTMLParser class directly (i.e. no subclassing), thereby making it significantly more terse:

def strip_html(text):
    parts = []                                                                      
    parser = HTMLParser()                                                           
    parser.handle_data = parts.append                                               
    parser.feed(text)                                                               
    return ''.join(parts)

You can use the following SQL to compare both date and time -

Select * From temp where mydate > STR_TO_DATE('2009-06-29 04:00:44', '%Y-%m-%d %H:%i:%s');

Attached mysql output when I used same SQL on same kind of table and field that you mentioned in the problem-

It should work perfect.

`pip -v` or `pip --v` 

However note, if you are using macos catelina which has the zsh (z shell) it might give you a whole bunch of things, so the best option is to try install the version or start as -- pip3

This can be done by creating a .pgpass file in the home directory of the (Linux) User. .pgpass file format:

<databaseip>:<port>:<databasename>:<dbusername>:<password>

You can also use wild card * in place of details.

Say I wanted to run tmp.sql without prompting for a password.

With the following code you can in *.sh file

echo "192.168.1.1:*:*:postgres:postgrespwd" > $HOME/.pgpass
echo "` chmod 0600 $HOME/.pgpass `"

echo " ` psql -h 192.168.1.1 -p 5432  -U postgres  postgres  -f tmp.sql `        

dotnet now includes a command for gitignore.

Open cmd.exe from your project folder and type:

dotnet new gitignore

The default behavior of Commit PL/SQL block:

You should explicitly commit or roll back every transaction. Whether you issue the commit or rollback in your PL/SQL program or from a client program depends on the application logic. If you do not commit or roll back a transaction explicitly, the client environment determines its final state.

For example, in the SQLPlus environment, if your PL/SQL block does not include a COMMIT or ROLLBACK statement, the final state of your transaction depends on what you do after running the block. If you execute a data definition, data control, or COMMIT statement or if you issue the EXIT, DISCONNECT, or QUIT command, Oracle commits the transaction. If you execute a ROLLBACK statement or abort the SQLPlus session, Oracle rolls back the transaction.

I'm not a java expert but I solve your problem like this:

@FunctionalInterface
public interface AutoCompleteCallable<T> {
  String call(T model) throws Exception;
}

I define the parameter in my special Interface

public <T> void initialize(List<T> entries, AutoCompleteCallable getSearchText) {.......
//call here
String value = getSearchText.call(item);
...
}

Finally, I implement getSearchText method while calling initialize method.

initialize(getMessageContactModelList(), new AutoCompleteCallable() {
          @Override
          public String call(Object model) throws Exception {
            return "custom string" + ((xxxModel)model.getTitle());
          }
        })

I actually like MY JavaScript files to be validated, but I definitely don't want to validate and deal with trivial warnings with third party libraries.

That's why I think that turning off validation all together is too drastic. Fortunately with Eclipse, you can selectively remove some JavaScript sources from validation.

1. Right-click your project.
2. Navigate to: Properties ? JavaScript ? Include Path
3. Select Source tab. (It looks identical to Java Build Path Source tab.)
4. Expand JavaScript source folder.
5. Highlight Excluded pattern.
6. Press the Edit button.
7. Press the Add button next to Exclusion patterns box.
8. You may either type Ant-style wildcard pattern, or click Browse button to mention the JavaScript source by name.

The information about JavaScript source inclusion/exclusion is saved into .settings/.jsdtscope file. Do not forget to add it to your SCM.

Here is how configuration looks with jQuery files removed from validation:

The hidden-* and visible-* classes no longer exist in Bootstrap 4. The same fucntion can be achieved in Bootstrap 4 by using the d-* for the specific tiers.

for me works this two commands:

git checkout commit_id
git push origin +name_of_branch

Yes, I understood your problem. If is difficult to identify cell has Numeric or Data value.

If you want data in format that shows in Excel, you just need to format cell using DataFormatter class.

DataFormatter dataFormatter = new DataFormatter();
String cellStringValue = dataFormatter.formatCellValue(row.getCell(0));
System.out.println ("Is shows data as show in Excel file" + cellStringValue);  // Here it automcatically format data based on that cell format.
// No need for extra efforts 

I had a situation where I needed to update or insert on a table according to two fields (both foreign keys) on which I couldn't set a UNIQUE constraint (so INSERT ... ON DUPLICATE KEY UPDATE won't work). Here's what I ended up using:

replace into last_recogs (id, hasher_id, hash_id, last_recog) 
  select l.* from 
    (select id, hasher_id, hash_id, [new_value] from last_recogs 
     where hasher_id in (select id from hashers where name=[hasher_name])
     and hash_id in (select id from hashes where name=[hash_name]) 
     union 
     select 0, m.id, h.id, [new_value] 
     from hashers m cross join hashes h 
     where m.name=[hasher_name] 
     and h.name=[hash_name]) l 
  limit 1;

This example is cribbed from one of my databases, with the input parameters (two names and a number) replaced with [hasher_name], [hash_name], and [new_value]. The nested SELECT...LIMIT 1 pulls the first of either the existing record or a new record (last_recogs.id is an autoincrement primary key) and uses that as the value input into the REPLACE INTO.

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

if all things were said didn't work, go back to basics and test if this is working:

<html>
  <head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
  </head>
  <body>
    <script type="text/javascript">
      $('body').click(function() {
        // do something here like:
        alert('hey! The body click is working!!!')
      });
    </script>
  </body>
</html>

then tell me if its working or not.

String.prototype.charCodeAt() can convert string characters to ASCII numbers. For example:

"ABC".charCodeAt(0) // returns 65

For opposite use String.fromCharCode(10) that convert numbers to equal ASCII character. This function can accept multiple numbers and join all the characters then return the string. Example:

String.fromCharCode(65,66,67); // returns 'ABC'

Here is a quick ASCII characters reference:

In my case there was a problem with a git pre-push hook.

Run git push --verbose to see if there are any errors.

Double check your git-hooks in the directory .git/hooks or move them temporarily to another place and see if everything works after that.

Here is an example using css3:

CSS:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    padding: 10px;
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}
.footer {
    position: relative;
    clear:both;
}

HTML:

<div id="wrap">
    body content....
</div>
<footer class="footer">
    footer content....
</footer>

jsfiddle

Update
As @Martin pointed, the ´position: relative´ is not mandatory on the .footer element, the same for clear:both. These properties are only there as an example. So, the minimum css necessary to stick the footer on the bottom should be:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}

Also, there is an excellent article at css-tricks showing different ways to do this: https://css-tricks.com/couple-takes-sticky-footer/

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

I wanted a more permanent and quicker way. Because I tend to forget to add extra lines before writing my actual Update/Insert queries.

I did it by checking SET IMPLICIT_TRANSACTIONS check-box from Options. To navigate to Options Select Tools>Options>Query Execution>SQL Server>ANSI in your Microsoft SQL Server Management Studio.

Just make sure to execute commit or rollback after you are done executing your queries. Otherwise, the table you would have run the query will be locked for others.

Use map::find

if ( m.find("f") == m.end() ) {
  // not found
} else {
  // found
}

If it is asking you for a username and password, your origin remote is pointing at the HTTPS URL rather than the SSH URL.

Change it to ssh.

For example, a GitHub project like Git will have an HTTPS URL:

https://github.com/<Username>/<Project>.git

And the SSH one:

[email protected]:<Username>/<Project>.git

You can do:

git remote set-url origin [email protected]:<Username>/<Project>.git

to change the URL.

You can do this concisely using the toolbelt vg. It's a light layer on top of numpy and it supports single values and stacked vectors.

import numpy as np
import vg

x = np.array([1, 2, 3, 4, 5])
mag1 = np.linalg.norm(x)
mag2 = vg.magnitude(x)
print mag1 == mag2
# True

If you want to use a plain javascript API, there is a good example at https://github.com/hongkiat/js-rss-reader/

The complete description at https://www.hongkiat.com/blog/rss-reader-in-javascript/

It uses fetch method as a global method that asynchronously fetches a resource. Below is a snap of code:

fetch(websiteUrl).then((res) => {
  res.text().then((htmlTxt) => {
    var domParser = new DOMParser()
    let doc = domParser.parseFromString(htmlTxt, 'text/html')
    var feedUrl = doc.querySelector('link[type="application/rss+xml"]').href
  })
}).catch(() => console.error('Error in fetching the website'))

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

In the java project, open .settings folder. there locate the file named "org.eclipse.wst.common.component" . Change tag <wb-module deploy-name="NEW_NAME"> .

Also you may want to change context root in project properties

I have been working on Swagger equivalent documentation library called Springfox nowadays and I found that in the Spring 5.0.8 (running at present), interface WebMvcConfigurer has been implemented by class WebMvcConfigurationSupport class which we can directly extend.

import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

public class WebConfig extends WebMvcConfigurationSupport { }

And this is how I have used it for setting my resource handling mechanism as follows -

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
            .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

You might check out the substr function in php and grab the first character that way:

http://php.net/manual/en/function.substr.php

if (substr('_abcdef', 0, 1) === '_') { ... }

Try this:

string text = "My text that I want to display";
MessageBox.Show(text);

The other answers assume that the array contains strings. My method is better, because it will work even if the array contains null, undefined, or other non-strings.

var notdefined;
var myarray = ['a', 'c', null, notdefined, 'nulk', 'BYE', 'nulm'];

myarray.sort(ignoreCase);

alert(JSON.stringify(myarray));    // show the result

function ignoreCase(a,b) {
    return (''+a).toUpperCase() < (''+b).toUpperCase() ? -1 : 1;
}

The null will be sorted between 'nulk' and 'nulm'. But the undefined will be always sorted last.

If you are using Visual Studio, there is an easy way to setup and enable SSL using IIS Express explained here

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

Spark 2.2+

Spark 2.2 introduces typedLit to support Seq, Map, and Tuples (SPARK-19254) and following calls should be supported (Scala):

import org.apache.spark.sql.functions.typedLit

df.withColumn("some_array", typedLit(Seq(1, 2, 3)))
df.withColumn("some_struct", typedLit(("foo", 1, 0.3)))
df.withColumn("some_map", typedLit(Map("key1" -> 1, "key2" -> 2)))

Spark 1.3+ (lit), 1.4+ (array, struct), 2.0+ (map):

The second argument for DataFrame.withColumn should be a Column so you have to use a literal:

from pyspark.sql.functions import lit

df.withColumn('new_column', lit(10))

If you need complex columns you can build these using blocks like array:

from pyspark.sql.functions import array, create_map, struct

df.withColumn("some_array", array(lit(1), lit(2), lit(3)))
df.withColumn("some_struct", struct(lit("foo"), lit(1), lit(.3)))
df.withColumn("some_map", create_map(lit("key1"), lit(1), lit("key2"), lit(2)))

Exactly the same methods can be used in Scala.

import org.apache.spark.sql.functions.{array, lit, map, struct}

df.withColumn("new_column", lit(10))
df.withColumn("map", map(lit("key1"), lit(1), lit("key2"), lit(2)))

To provide names for structs use either alias on each field:

df.withColumn(
    "some_struct",
    struct(lit("foo").alias("x"), lit(1).alias("y"), lit(0.3).alias("z"))
 )

or cast on the whole object

df.withColumn(
    "some_struct", 
    struct(lit("foo"), lit(1), lit(0.3)).cast("struct<x: string, y: integer, z: double>")
 )

It is also possible, although slower, to use an UDF.

Note:

The same constructs can be used to pass constant arguments to UDFs or SQL functions.

Had problems even when init.py existed in subfolder and all that was missing was adding 'as' after import

from folder.file import Class as Class
import folder.file as functions

You are also able to do some text manipulation inside the braces:

STRING="./folder/subfolder/file.txt"
echo ${STRING} ${STRING%/*/*}

Result:

./folder/subfolder/file.txt ./folder

or

STRING="This is a string"
echo ${STRING// /_}

Result:

This_is_a_string

You are right in "regular variables" are not needed... But it is more helpful for the debugging and to read a script.

I've used Quick Highlighter a lot. Works great for a huge list of languages.

One thing i've noticed is: spring CronTrigger is not cron. You may end up with 7 parameters in a valid cron expression (wich you can validate on cronmaker.com) and then spring not accept it. Most of cases you just delete the last parameter and everything works fine.

Enumerable.SequenceEqual Method

Determines whether two sequences are equal according to an equality comparer. MS.Docs

Enumerable.SequenceEqual(list1, list2);

This works for all primitive data types. If you need to use it on custom objects you need to implement IEqualityComparer

Defines methods to support the comparison of objects for equality.

IEqualityComparer Interface

Defines methods to support the comparison of objects for equality. MS.Docs for IEqualityComparer

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

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

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

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

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

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

If it only happens on mapped drives it might be bug https://bitbucket.org/tortoisehg/thg/issue/889/cant-commit-file-over-network-share. Using UNC path instead of drive letter seems to sidestep the issue.

You can use the "vh" length unit for the min-height property of the element itself and its parents. It's supported since IE9:

<body class="full-height">
    <form id="form1">
    <div id="header">
        <a title="Home" href="index.html" />
    </div>

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

    <div id="content" class="full-height">
    </div>
</body>

CSS:

.full-height {
    min-height: 100vh;
    box-sizing: border-box;
}

Using docker-compose, you can inherit env variables in docker-compose.yml and subsequently any Dockerfile(s) called by docker-compose to build images. This is useful when the Dockerfile RUN command should execute commands specific to the environment.

(your shell has RAILS_ENV=development already existing in the environment)

docker-compose.yml:

version: '3.1'
services:
  my-service: 
    build:
      #$RAILS_ENV is referencing the shell environment RAILS_ENV variable
      #and passing it to the Dockerfile ARG RAILS_ENV
      #the syntax below ensures that the RAILS_ENV arg will default to 
      #production if empty.
      #note that is dockerfile: is not specified it assumes file name: Dockerfile
      context: .
      args:
        - RAILS_ENV=${RAILS_ENV:-production}
    environment: 
      - RAILS_ENV=${RAILS_ENV:-production}

Dockerfile:

FROM ruby:2.3.4

#give ARG RAILS_ENV a default value = production
ARG RAILS_ENV=production

#assign the $RAILS_ENV arg to the RAILS_ENV ENV so that it can be accessed
#by the subsequent RUN call within the container
ENV RAILS_ENV $RAILS_ENV

#the subsequent RUN call accesses the RAILS_ENV ENV variable within the container
RUN if [ "$RAILS_ENV" = "production" ] ; then echo "production env"; else echo "non-production env: $RAILS_ENV"; fi

This way, I don't need to specify environment variables in files or docker-compose build/up commands:

docker-compose build
docker-compose up

As this error comes when you are trying to insert non-numeric value into a numeric column in db it seems that your last field might be numeric and you are trying to send it as a string in database. check your last value.

I wrote all about tabs in vim, which gives a few interesting things you didn't ask about. To automatically indent braces, use:

:set cindent

To indent two spaces (instead of one tab of eight spaces, the vim default):

:set shiftwidth=2

To keep vim from converting eight spaces into tabs:

:set expandtab

If you ever want to change the indentation of a block of text, use < and >. I usually use this in conjunction with block-select mode (v, select a block of text, < or >).

(I'd try to talk you out of using two-space indentation, since I (and most other people) find it hard to read, but that's another discussion.)

Try negation operator ! before $(this):

if (!$(this).parent().next().is('ul')){

You can use percent values:

background: yellow url("arrow1.gif") no-repeat 95% 50%;

Not pixel perfect, but…

Such thing is easy with ggplot2

library(ggplot2)
dataset <- data.frame(X = c(rep(65, times=5), rep(25, times=5), 
                            rep(35, times=10), rep(45, times=4)))
ggplot(dataset, aes(x = X)) + 
  geom_histogram(aes(y = ..density..)) + 
  geom_density()

or to mimic the result from Dirk's solution

ggplot(dataset, aes(x = X)) + 
  geom_histogram(aes(y = ..density..), binwidth = 5) + 
  geom_density()

Add builtin COPY in project.csproj file:

  <Project>
    ...
    <Target Name="AfterBuild">
      <Copy SourceFiles="$(ProjectDir)..\..\Lib\*.dll" DestinationFolder="$(OutDir)Debug\bin" SkipUnchangedFiles="false" />
      <Copy SourceFiles="$(ProjectDir)..\..\Lib\*.dll" DestinationFolder="$(OutDir)Release\bin" SkipUnchangedFiles="false" />
    </Target>
  </Project>

Try doing it the other way around.

$('<link rel="stylesheet" href="css/style2.css" type="text/css" />').appendTo('head');

I had similar issue, trying to load data from Excel spreadsheet; and was running on WinX64. So I went VS BI`s project properties: Configuration Properties \ Dbugging and Switch Run64BitRuntime from True to False. It worked.

something like that?

'nearest
 n = 5
 'n = 10

 'value
 v = 496
 'v = 499 
 'v = 2348 
 'v = 7343

 'mod
 m = (v \ n) * n

 'diff between mod and the val
 i = v-m


 if i >= (n/2) then     
      msgbox m+n
 else
      msgbox m
 end if

Met this problem when I created a branch based on branch A by

git checkout -b a

and then I set the up stream of branch a to origin branch B by

git branch -u origin/B

Then I got the error message above.

One way to solve this problem for me was,

• Delete the branch a
• Create a new branch b by

git checkout -b b origin/B

I've used something else (I think better...) and want to share it:

I created a VIEW that has a "group" clause

CREATE VIEW vCountries AS SELECT * PROVINCES GROUP BY country_code

SELECT * FROM client INNER JOIN vCountries on client_province = province_id

I want to say yet, that I think that we need to do this solution BECAUSE WE DID SOMETHING WRONG IN THE ANALYSIS... at least in my case... but sometimes it's cheaper to do this that to redesign everything...

I hope it helps!

You can also use:

import re

def sort_human(l):
    convert = lambda text: float(text) if text.isdigit() else text
    alphanum = lambda key: [convert(c) for c in re.split('([-+]?[0-9]*\.?[0-9]*)', key)]
    l.sort(key=alphanum)
    return l

This is very similar to other stuff that you can find on the internet but also works for alphanumericals like [abc0.1, abc0.2, ...].

Modification of @Ilya_Gazman answer

    private void callJavaScript(WebView view, String methodName, Object...params){
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("javascript:try{");
        stringBuilder.append(methodName);
        stringBuilder.append("(");
        String separator = "";
        for (Object param : params) {               
            stringBuilder.append(separator);
            separator = ",";
            if(param instanceof String){
                stringBuilder.append("'");
            }
                stringBuilder.append(param.toString().replace("'", "\\'"));
            if(param instanceof String){
                stringBuilder.append("'");
            }

        }
        stringBuilder.append(")}catch(error){console.error(error.message);}");
        final String call = stringBuilder.toString();
        Log.i(TAG, "callJavaScript: call="+call);


        view.loadUrl(call);
    }

will correctly create JS calls e.g.

callJavaScript(mBrowser, "alert", "abc", "def");
//javascript:try{alert('abc','def')}catch(error){console.error(error.message);}
callJavaScript(mBrowser, "alert", 1, true, "abc");
//javascript:try{alert(1,true,'abc')}catch(error){console.error(error.message);}

Note that objects will not be passed correctly - but you can serialize them before passing as an argument.

Also I've changed where the error goes, I've diverted it to the console log which can be listened by:

    webView.setWebChromeClient(new CustomWebChromeClient());

and client

class CustomWebChromeClient extends WebChromeClient {
    private static final String TAG = "CustomWebChromeClient";

    @Override
    public boolean onConsoleMessage(ConsoleMessage cm) {
        Log.d(TAG, String.format("%s @ %d: %s", cm.message(),
                cm.lineNumber(), cm.sourceId()));
        return true;
    }
}

Tested alone, <select class=input-xxlarge> sets the content width of the element to 530px. (The total width of the element is slightly smaller than that of <input class=input-xxlarge> due to different padding. If this a a problem, set the paddings in your own style sheet as desired.)

So if it does not work, the effect is prevented by some setting in your own style sheet or maybe in the use other settings for the element.

Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:

<xsl:template match="class">
  <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  <xsl:variable name="subexists">
    <xsl:choose>
      <xsl:when test="joined-subclass">true</xsl:when>
      <xsl:otherwise>false</xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

And if you need the variable to have "global" scope then declare it outside of the template:

<xsl:variable name="subexists">
  <xsl:choose>
     <xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
     <xsl:otherwise>false</xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<xsl:template match="class">
   subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

From Effective Go:

Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.

Slices and arrays are always evaluated during runtime:

var TestSlice = []float32 {.03, .02}
var TestArray = [2]float32 {.03, .02}
var TestArray2 = [...]float32 {.03, .02}

[...] tells the compiler to figure out the length of the array itself. Slices wrap arrays and are easier to work with in most cases. Instead of using constants, just make the variables unaccessible to other packages by using a lower case first letter:

var ThisIsPublic = [2]float32 {.03, .02}
var thisIsPrivate = [2]float32 {.03, .02}

thisIsPrivate is available only in the package it is defined. If you need read access from outside, you can write a simple getter function (see Getters in golang).

You can do it in two ways:

First:

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    const listItems = data.map((d) => <li key={d.name}>{d.name}</li>);

    return (
      <div>
      {listItems }
      </div>
    );
  }

Second: Directly write the map function in the return

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    return (
      <div>
      {data.map(function(d, idx){
         return (<li key={idx}>{d.name}</li>)
       })}
      </div>
    );
  }

/* array literal */
var aData = [];

/* object constructur */
function Person(firstname, lastname) {
  this.firstname = firstname;
  this.lastname = lastname;
  this.fullname = function() {
    return (this.firstname + " " + this.lastname);
  };
}

/* store object into array */
aData[aData.length] = new Person("Java", "Script"); // aData[0]

aData.push(new Person("Jhon", "Doe"));
aData.push(new Person("Anna", "Smith"));
aData.push(new Person("Black", "Pearl"));

aData[aData.length] = new Person("stack", "overflow"); // aData[4]

/* loop array */
for (var i in aData) {
  alert(aData[i].fullname());
}

/* convert array of object into string json */
var jsonString = JSON.stringify(aData);
document.write(jsonString);

Push object into array

I was also facing same kind of problem on my Macbook Pro. I took these very simple steps and freshly installed Android Studio.

** Link Contains Images, look if facing any problem.

These Very Simple Steps Can Solve Your Problem.

1. Type "Command+option+Space Bar"
2. Type "Android Studio"
3. Click '+' button just below search box.
4. A new bar will come up "Kind" is "any" click on "kind" --> Others --> search for "system file" and select that by putting a tick mark.! And click on Ok.
5. Then select "are included" from the drop down menu !
6. Then you get a lot of system file that need to be deleted to complete the fully un-installation of any app.
7. Click "command+A" to select all files and take a look on the file remove is some video files are also included. And click "command + Delete"
8. Empty your trash. Done

The answer by Alasdair covers the basics

• Identify the migrations you want by ./manage.py showmigrations
• migrate using the app name and the migration name

But it should be pointed out that not all migrations can be reversed. This happens if Django doesn't have a rule to do the reversal. For most changes that you automatically made migrations by ./manage.py makemigrations, the reversal will be possible. However, custom scripts will need to have both a forward and reverse written, as described in the example here:

https://docs.djangoproject.com/en/1.9/ref/migration-operations/

How to do a no-op reversal

If you had a RunPython operation, then maybe you just want to back out the migration without writing a logically rigorous reversal script. The following quick hack to the example from the docs (above link) allows this, leaving the database in the same state that it was after the migration was applied, even after reversing it.

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import migrations, models

def forwards_func(apps, schema_editor):
    # We get the model from the versioned app registry;
    # if we directly import it, it'll be the wrong version
    Country = apps.get_model("myapp", "Country")
    db_alias = schema_editor.connection.alias
    Country.objects.using(db_alias).bulk_create([
        Country(name="USA", code="us"),
        Country(name="France", code="fr"),
    ])

class Migration(migrations.Migration):

    dependencies = []

    operations = [
        migrations.RunPython(forwards_func, lambda apps, schema_editor: None),
    ]

This works for Django 1.8, 1.9

Update: A better way of writing this would be to replace lambda apps, schema_editor: None with migrations.RunPython.noop in the snippet above. These are both functionally the same thing. (credit to the comments)

Looking at the "effective POM" will probably help too. For instance, if you wanted to know what the path is for ${project.build.sourceDirectory}

you would find the related XML in the effective POM, such as: <project> <build> <sourceDirectory>/my/path</sourceDirectory>

Also helpful - you can do a real time evaluation of properties via the command line execution of mvn help:evaluate while in the same dir as the POM.

In my case I had a problem with nodejs and 'npm i' from a remote repository. I fixed it added 'node' user to nodejs container and 700 to ~/.ssh in container.

Dockerfile:

USER node #added the part
COPY run.sh /usr/local/bin/
CMD ["run.sh"]

run.sh:

#!/bin/bash
chmod 700 -R ~/.ssh/; #added the part

docker-compose.yml:

nodejs:
      build: ./nodejs/10/
      container_name: nodejs
      restart: always
      ports:
        - "3000:3000"
      volumes:
        - ../www/:/var/www/html/:delegated
        - ./ssh:/home/node/.ssh #added the part
      links:
        - mailhog
      networks:
        - work-network

after that it started works

I use SwitchToThisWindow to bring the application to the forefront as in this example:

static class Program

    [DllImport("User32.dll", SetLastError = true)]
    static extern void SwitchToThisWindow(IntPtr hWnd, bool fAltTab);



    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        bool createdNew;
        int iP;
        Process currentProcess = Process.GetCurrentProcess();
        Mutex m = new Mutex(true, "XYZ", out createdNew);
        if (!createdNew)
        {
            // app is already running...
            Process[] proc = Process.GetProcessesByName("XYZ");

            // switch to other process
            for (iP = 0; iP < proc.Length; iP++)
            {
                if (proc[iP].Id != currentProcess.Id)
                    SwitchToThisWindow(proc[0].MainWindowHandle, true);
            }

            return;
        }

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new form());
        GC.KeepAlive(m);

    }

I was able to overcome this issue with the following Visual Studio 2017 change:

1. In Team Explorer, go to Settings. Go to Global Settings to configure this option at the global level; go to Repository Settings to configure this option at the repo level.
2. Set Rebase local branch when pulling to the desired setting (for me it was True), and select Update to save.

See: https://docs.microsoft.com/en-us/vsts/git/concepts/git-config?view=vsts&tabs=visual-studio#rebase-local-branch-when-pulling

The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *, ?, [...].

To get the output of a command in an array, with one line per element, there are essentially 3 ways:

1. With Bash=4 use mapfile—it's the most efficient:

   mapfile -t my_array < <( my_command )
   

2. Otherwise, a loop reading the output (slower, but safe):

   my_array=()
   while IFS= read -r line; do
       my_array+=( "$line" )
   done < <( my_command )
   

3. As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:

   IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
   

   Please make sure you use exactly this form, i.e., make sure you have the following:

   • IFS=$'\n' on the same line as the read statement: this will only set the environment variable IFS for the read statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read to break the stream at the EOL character \n.
   • -r: this is important. It tells read to not interpret the backslashes as escape sequences.
   • -d '': please note the space between the -d option and its argument ''. If you don't leave a space here, the '' will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read to stop reading at the nil byte. Some people write it as -d $'\0', but it is not really necessary. -d '' is better.
   • -a my_array tells read to populate the array my_array while reading the stream.
   • You must use the printf '\0' statement after my_command, so that read returns 0; it's actually not a big deal if you don't (you'll just get an return code 1, which is okay if you don't use set -e – which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf '', which doesn't output anything. printf '\0' prints a null byte, needed by read to happily stop reading there (remember the -d '' option?).

If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.

If you want to use read, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]} in the example I gave).

Note that mapfile provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile and the options -C and -c therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).

Now I'm going to tell you why the following method:

my_array=( $( my_command) )

is broken when there are spaces:

$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!

Then some people will then recommend using IFS=$'\n' to fix it:

$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!

But now let's use another command, with globs:

$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?

That's because I have a file called t in the current directory… and this filename is matched by the glob [three four]… at this point some people would recommend using set -f to disable globbing: but look at it: you have to change IFS and use set -f to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.

$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'

here we're working with the shell!

As nobody seems to have mentioned it...

svn propedit svn:ignore .

Then edit the contents of the file to specify the patterns to ignore, exit the editor and you're all done.

This should be understood in the context of GitHub forks (where you fork a GitHub repo on GitHub before cloning that fork locally).

• upstream generally refers to the original repo that you have forked
  (see also "Definition of “downstream” and “upstream”" for more on upstream term)
• origin is your fork: your own repo on GitHub, clone of the original repo of GitHub

From the GitHub page:

When a repo is cloned, it has a default remote called origin that points to your fork on GitHub, not the original repo it was forked from.
To keep track of the original repo, you need to add another remote named upstream

git remote add upstream git://github.com/<aUser>/<aRepo.git>

(with aUser/aRepo the reference for the original creator and repository, that you have forked)

You will use upstream to fetch from the original repo (in order to keep your local copy in sync with the project you want to contribute to).

git fetch upstream

(git fetch alone would fetch from origin by default, which is not what is needed here)

You will use origin to pull and push since you can contribute to your own repository.

git pull
git push

(again, without parameters, 'origin' is used by default)

You will contribute back to the upstream repo by making a pull request.

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.

seems fairly clear-cut: your OS can't find enough RAM to start a new Java process, which is in this case the Gradle builder. Perhaps you don't have enough RAM, or not enough swap, or you have too many other memory-hungry processes running at the same time.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

Given

std::vector<Rule>& topPriorityRules;

The correct way to remove the first element of the referenced vector is

topPriorityRules.erase(topPriorityRules.begin());

which is exactly what you suggested.

Looks like i need to do iterator overloading.

There is no need to overload an iterator in order to erase first element of std::vector.

P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

You can subset using a vector of column names. I strongly prefer this approach over those that treat column names as if they are object names (e.g. subset()), especially when programming in functions, packages, or applications.

# data for reproducible example
# (and to avoid confusion from trying to subset `stats::df`)
df <- setNames(data.frame(as.list(1:5)), LETTERS[1:5])
# subset
df[c("A","B","E")]

Note there's no comma (i.e. it's not df[,c("A","B","C")]). That's because df[,"A"] returns a vector, not a data frame. But df["A"] will always return a data frame.

str(df["A"])
## 'data.frame':    1 obs. of  1 variable:
## $ A: int 1
str(df[,"A"])  # vector
##  int 1

Thanks to David Dorchies for pointing out that df[,"A"] returns a vector instead of a data.frame, and to Antoine Fabri for suggesting a better alternative (above) to my original solution (below).

# subset (original solution--not recommended)
df[,c("A","B","E")]  # returns a data.frame
df[,"A"]             # returns a vector

Try to use document.createEvent described here https://developer.mozilla.org/en-US/docs/Web/API/document.createEvent

The code for function that simulates click should look something like this:

function simulateClick() {
  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
  var a = document.getElementById("gift-close"); 
  a.dispatchEvent(evt);      
}

I hate the PostBuild step, it allows for too much stuff to happen outside of the build tool's purview. I believe that its better to let MSBuild manage the copy process, and do the updating. You can edit the .csproj file like this:

  <Target Name="AfterBuild" Inputs="$(TargetPath)\**">
    <Copy SourceFiles="$(TargetPath)\**" DestinationFiles="$(SolutionDir)Prism4Demo.Shell\$(OutDir)Modules\**" OverwriteReadOnlyFiles="true"></Copy>
  </Target>

I've been playing around with ways to overcome this issue, and believe I have found a solution:

If you can write your application for Internet Explorer 9 (and later) and all other modern browsers that support CSS calc(), rem units, and vmin units. You can use this to achieve scalable text without media queries:

body {
  font-size: calc(0.75em + 1vmin);
}

Here it is in action: http://codepen.io/csuwldcat/pen/qOqVNO

You can parse the geolocation through the addresses. Create an Array with jquery like this:

//follow this structure
var addressesArray = [
  'Address Str.No, Postal Area/city'
]

//loop all the addresses and call a marker for each one
for (var x = 0; x < addressesArray.length; x++) {
  $.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addressesArray[x]+'&sensor=false', null, function (data) {
    var p = data.results[0].geometry.location
    var latlng = new google.maps.LatLng(p.lat, p.lng);
    //it will place marker based on the addresses, which they will be translated as geolocations.
    var aMarker= new google.maps.Marker({
      position: latlng,
      map: map
    });
  });
}

Also please note that Google limit your results if you don't have a business account with them, and you my get an error if you use too many addresses.

Actually, although I blogged (see Luke's answer), I think this is better than my IDisposable wrapper. Typical code:

Service<IOrderService>.Use(orderService=>
{
  orderService.PlaceOrder(request);
}); 

(edit per comments)

Since Use returns void, the easiest way to handle return values is via a captured variable:

int newOrderId = 0; // need a value for definite assignment
Service<IOrderService>.Use(orderService=>
  {
    newOrderId = orderService.PlaceOrder(request);
  });
Console.WriteLine(newOrderId); // should be updated

SQL Server uses Julian dates so your 30 means "30 calendar days". getdate() - 0.02083 means "30 minutes ago".

I am always used DateDiff(day,date1,date2) to compare two date.

Checkout following example. Just copy that and run in Ms sql server. Also, try with change date by 31 dec to 30 dec and check result

BEGIN

declare @firstDate datetime
declare @secondDate datetime


declare @chkDay int

set @firstDate ='2010-12-31 15:13:48.593'
set @secondDate ='2010-12-31 00:00:00.000'

set @chkDay=Datediff(day,@firstDate ,@secondDate )

if @chkDay=0
    Begin
        Print 'Date is Same'
    end
else
    Begin
        Print 'Date is not Same'
    end
End

start wgnplot.exe "c:\path to file to open\foo.dat"

Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)

Do it the other way around:

$a = "1,435";
$b = str_replace( ',', '', $a );

if( is_numeric( $b ) ) {
    $a = $b;
}

The easiest would be:

$var = intval(preg_replace('/[^\d.]/', '', $var));

or if you need float:

$var = floatval(preg_replace('/[^\d.]/', '', $var));

My previous answer was not enough accurate. As truly it was horrible :D But now I can post much more useful and correct answer.

I did some additional tests. You can find it's source by the following link and reCheck it on your environment by your own: https://github.com/ukushu/DataStructuresTestsAndOther.git

Short results:

• Array need to use:

  • So often as possible. It's fast and takes smallest RAM range for same amount information.
  • If you know exact count of cells needed
  • If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
  • If needed high Random Access speed

• List need to use:

  • If needed to add cells to the end of list (often)
  • If needed to add cells in the beginning/middle of the list (NOT OFTEN)
  • If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
  • If needed high Random Access speed

• LinkedList need to use:

  • If needed to add cells in the beginning/middle/end of the list (often)
  • If needed only sequential access (forward/backward)
  • If you need to save LARGE items, but items count is low.
  • Better do not use for large amount of items, as it's use additional memory for links.

More details:

Interesting to know:

1. LinkedList<T> internally is not a List in .NET. It's even does not implement IList<T>. And that's why there are absent indexes and methods related to indexes.

2. LinkedList<T> is node-pointer based collection. In .NET it's in doubly linked implementation. This means that prior/next elements have link to current element. And data is fragmented -- different list objects can be located in different places of RAM. Also there will be more memory used for LinkedList<T> than for List<T> or Array.

3. List<T> in .Net is Java's alternative of ArrayList<T>. This means that this is array wrapper. So it's allocated in memory as one contiguous block of data. If allocated data size exceeds 85000 bytes, it will be moved to Large Object Heap. Depending on the size, this can lead to heap fragmentation(a mild form of memory leak). But in the same time if size < 85000 bytes -- this provides a very compact and fast-access representation in memory.

4. Single contiguous block is preferred for random access performance and memory consumption but for collections that need to change size regularly a structure such as an Array generally need to be copied to a new location whereas a linked list only needs to manage the memory for the newly inserted/deleted nodes.

I searched and searched and finally found that ie needs to know the map size. Set the map size to match the div size.

map = new GMap2(document.getElementById("map_canvas2"), { size: new GSize(850, 600) });

<div id="map_canvas2" style="width: 850px; height: 600px">
</div>

You can do this conversion with the OpenSSL library

http://www.openssl.org/

Windows binaries can be found here:

http://www.slproweb.com/products/Win32OpenSSL.html

Once you have the library installed, the command you need to issue is:

openssl x509 -in mycert.crt -out mycert.pem -outform PEM

Replace all latters from any language in 'A', and if you wish for example all digits to 0:

return str.replace(/[^\s!-@[-`{-~]/g, "A").replace(/\d/g, "0");

In Typescript with relative path to the icon:

import path from 'path';

route.get('/favicon.ico', (_req, res) => res.sendFile(path.join(__dirname, '../static/myicon.png')));

I was also getting the same error, the WCF was working properly for me when i was using it in the Dev Environment with my credentials, but when someone else was using it in TEST, it was throwing the same error. I did a lot of research, and then instead of doing config updates, handled an exception in the WCF method with the help of fault exception. Also the identity for the WCF needs to be set with the same credentials which are having access in the database, someone might have changed your authority. Please find below the code for the same:

 [ServiceContract]
public interface IService1
{
    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    ForDataset GetCCDBdata();

    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    string GetCCDBdataasXMLstring();


    //[OperationContract]
    //string GetData(int value);

    //[OperationContract]
    //CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}

  [DataContract]
public class ServiceData
{
    [DataMember]
    public bool Result { get; set; }
    [DataMember]
    public string ErrorMessage { get; set; }
    [DataMember]
    public string ErrorDetails { get; set; }
}

in your service1.svc.cs you can use this in the catch block:

 catch (Exception ex)
        {
            myServiceData.Result = false;
            myServiceData.ErrorMessage = "unforeseen error occured. Please try later.";
            myServiceData.ErrorDetails = ex.ToString();
            throw new FaultException<ServiceData>(myServiceData, ex.ToString());
        }

And use this in the Client application like below code:

  ConsoleApplicationWCFClient.CCDB_HIG_service.ForDataset ds = obj.GetCCDBdata();

            string str = obj.GetCCDBdataasXMLstring();

        }

        catch (FaultException<ConsoleApplicationWCFClient.CCDB_HIG_service.ServiceData> Fex)
      {
          Console.WriteLine("ErrorMessage::" + Fex.Detail.ErrorMessage + Environment.NewLine);
          Console.WriteLine("ErrorDetails::" + Environment.NewLine + Fex.Detail.ErrorDetails);
          Console.ReadLine();
      }

Just try this, it will help for sure to get the exact issue.

The low-level way would be to access the matrix data directly. In an RGB image (which I believe OpenCV typically stores as BGR), and assuming your cv::Mat variable is called frame, you could get the blue value at location (x, y) (from the top left) this way:

frame.data[frame.channels()*(frame.cols*y + x)];

Likewise, to get B, G, and R:

uchar b = frame.data[frame.channels()*(frame.cols*y + x) + 0];    
uchar g = frame.data[frame.channels()*(frame.cols*y + x) + 1];
uchar r = frame.data[frame.channels()*(frame.cols*y + x) + 2];

Note that this code assumes the stride is equal to the width of the image.

Wrap the name in a span, give it a class and assign a style to that class:

<td><span class="names">Name text you want bold</span> rest of your text</td>

style:

.names { font-weight: bold; }

<input id="inputFileToLoad" type="file" onchange="encodeImageFileAsURL();" />
<div id="imgTest"></div>
<script type='text/javascript'>
  function encodeImageFileAsURL() {

    var filesSelected = document.getElementById("inputFileToLoad").files;
    if (filesSelected.length > 0) {
      var fileToLoad = filesSelected[0];

      var fileReader = new FileReader();

      fileReader.onload = function(fileLoadedEvent) {
        var srcData = fileLoadedEvent.target.result; // <--- data: base64

        var newImage = document.createElement('img');
        newImage.src = srcData;

        document.getElementById("imgTest").innerHTML = newImage.outerHTML;
        alert("Converted Base64 version is " + document.getElementById("imgTest").innerHTML);
        console.log("Converted Base64 version is " + document.getElementById("imgTest").innerHTML);
      }
      fileReader.readAsDataURL(fileToLoad);
    }
  }
</script>

Based on Why does FtpWebRequest download files from the root directory? Can this cause a 553 error?, I wrote a PowerShell script that enabled to download a file from a FTP-Server via explicit FTP over TLS:

try{ 
    # Create a FTPWebRequest
    $FTPRequest = [System.Net.FtpWebRequest]::Create($RemoteFile)
    $FTPRequest.Credentials = New-Object System.Net.NetworkCredential($Username,$Password)
    $FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile
    $FTPRequest.UseBinary = $true

    # Loop through the download

    do {
        $ReadLength = $ResponseStream.Read($ReadBuffer,0,1024)
        $LocalFileFile.Write($ReadBuffer,0,$ReadLength)

My Git Bash shortcut on Windows complained when I put the cd to my work directory into ~/.bashrc

WARNING: Found ~/.bashrc but no ~/.bash_profile, ~/.bash_login or ~/.profile.

This looks like an incorrect setup.
A ~/.bash_profile that loads ~/.bashrc will be created for you.

So git created this .bash_profile:

$ cat ~/.bash_profile
# generated by Git for Windows
test -f ~/.profile && . ~/.profile
test -f ~/.bashrc && . ~/.bashrc

Which does the job.

Alternatively, you can just remove the .bashrc again and put the cd command into .bash_profile:

$ rm ~/.bashrc
$ echo "cd Source/Repos" >~/.bash_profile

$ cat ~/.bash_profile
cd Source/Repos

Once this is done you can close the Window and re-open it using your desktop shortcut and the prompt will tell you that your location is now where you wanted it - looks like this is my case:

Administrator@raptor1 MINGW64 ~/Source/Repos
$

I got the "hunks failed" message when I wasn't applying the patch in the top directory of the associated git project. I was applying the patch (where I created it) in a subdirectory.

It seems patches can be created from subdirectories within a git project, but not applied.

I came up with a specific solution that should be much more efficient than the cloning and modifying of the clone. This solution only works with the following two reservations, but should be more efficient than the currently accepted solution:

1. You are getting only the text
2. The text you want to extract is before the child elements

With that said, here is the code:

// 'element' is a jQuery element
function getText(element) {
  var text = element.text();
  var childLength = element.children().text().length;
  return text.slice(0, text.length - childLength);
}

When you call setAdapter, that does not immediately lay out and position items on the screen (that takes a single layout pass) hence your scrollToPosition() call has no actual elements to scroll to when you call it.

Instead, you should register a ViewTreeObserver.OnGlobalLayoutListener (via addOnGlobalLayoutListner() from a ViewTreeObserver created by conversationView.getViewTreeObserver()) which delays your scrollToPosition() until after the first layout pass:

conversationView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
  public void onGlobalLayout() {
    conversationView.scrollToPosition(GENERIC_MESSAGE_LIST.size();
    // Unregister the listener to only call scrollToPosition once
    conversationView.getViewTreeObserver().removeGlobalOnLayoutListener(this);

    // Use vto.removeOnGlobalLayoutListener(this) on API16+ devices as 
    // removeGlobalOnLayoutListener is deprecated.
    // They do the same thing, just a rename so your choice.
  }
});

If you dont want to use any module for age calculation

var age = Math.floor((new Date() - new Date(date_of_birth)) / 1000 / 60 / 60 / 24 / 365.25)

This is an easy way to split string by comma,

import java.util.*;

public class SeparatedByComma{
public static void main(String []args){
     String listOfStates = "Hasalak, Mahiyanganaya, Dambarawa, Colombo";
     List<String> stateList = Arrays.asList(listOfStates.split("\\,"));
     System.out.println(stateList);
 }
}

Constant initializer allowed by C++ Standard only for integral or enumeration types. See 9.4.2/4 for details:

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a name- space scope if it is used in the program and the namespace scope definition shall not contain an initializer.

And 9.4.2/7:

Static data members are initialized and destroyed exactly like non-local objects (3.6.2, 3.6.3).

So you should write somewhere in cpp file:

const char* SomeClass::SOMETHING = "sommething";

I had the same issue. Using MySQL 6.1 Workbench.

After a while (2 mins), it just crashed. Reported bug, saved files and reopened. It works now.

I guess I would suggest if that happens again, to immediately save the open scripts, close MySQL and restart it.

try "configuration properties -> debugging -> environment" and set the PATH variable in run-time

You can also try:

function getTagValue($string, $tag)
{
    $pattern = "/<{$tag}>(.*?)<\/{$tag}>/s";
    preg_match($pattern, $string, $matches);
    return isset($matches[1]) ? $matches[1] : '';
}

It returns empty string in case of no match.

From C#3.5 I assume you're using WPF.

Just make a two-way data binding from an integer property to your text-box. WPF will show the validation error for you automatically.

For the email case, make a two-way data binding from a string property that does Regexp validation in the setter and throw an Exception upon validation error.

Look up Binding on MSDN.

The easiest way is:

var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");

Try to avoid using null in Scala. It's really there only for interoperability with Java. In Scala, use Option for things that might be empty. If you're calling a Java API method that might return null, wrap it in an Option immediately.

def getObject : Option[QueueObject] = {
  // Wrap the Java result in an Option (this will become a Some or a None)
  Option(someJavaObject.getResponse)
}

Note: You don't need to put it in a val or use an explicit return statement in Scala; the result will be the value of the last expression in the block (in fact, since there's only one statement, you don't even need a block).

def getObject : Option[QueueObject] = Option(someJavaObject.getResponse)

Besides what the others have already shown (for example calling foreach on the Option, which might be slightly confusing), you could also call map on it (and ignore the result of the map operation if you don't need it):

getObject map QueueManager.add

This will do nothing if the Option is a None, and call QueueManager.add if it is a Some.

I find using a regular if however clearer and simpler than using any of these "tricks" just to avoid an indentation level. You could also just write it on one line:

if (getObject.isDefined) QueueManager.add(getObject.get)

or, if you want to deal with null instead of using Option:

if (getObject != null) QueueManager.add(getObject)

edit - Ben is right, be careful to not call getObject more than once if it has side-effects; better write it like this:

val result = getObject
if (result.isDefined) QueueManager.add(result.get)

or:

val result = getObject
if (result != null) QueueManager.add(result)

I cannot help you much without a small (possibly reduced) snippit of the problem. If the problem is what I think it is then it's because a div by default takes up 100% width, and as such cannot be aligned.

What you may be after is to align the inline elements inside the div (such as text) with text-align:center; otherwise you may consider setting the div to display:inline-block;

If you do go down the inline-block route then you may have to consider my favorite IE hack.

width:100px;
display:inline-block;
zoom:1; //IE only
*display:inline; //IE only

Happy Coding :)

when you use postfix it instantiates on more object in memory. Some people say that it is better to use suffix operator in for loop

For .NET 4.5 SystemCommands class will do the trick (.NET 4.0 users can use WPF Shell Extension google - Microsoft.Windows.Shell or Nicholas Solution).

    <Window.CommandBindings>
        <CommandBinding Command="{x:Static SystemCommands.CloseWindowCommand}" 
                        CanExecute="CloseWindow_CanExec" 
                        Executed="CloseWindow_Exec" />
    </Window.CommandBindings>
    <!-- Binding Close Command to the button control -->
    <Button ToolTip="Close Window" Content="Close" Command="{x:Static SystemCommands.CloseWindowCommand}"/>

In the Code Behind you can implement the handlers like this:

    private void CloseWindow_CanExec(object sender, CanExecuteRoutedEventArgs e)
    {
        e.CanExecute = true;
    }

    private void CloseWindow_Exec(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.CloseWindow(this);
    }

Disclaimer : I've created fast-xml-parser

I have created fast-xml-parser to parse a XML string into JS/JSON object or intermediate traversal object. It is expected to be compatible in all the browsers (however tested on Chrome, Firefox, and IE only).

Usage

var options = { //default
    attrPrefix : "@_",
    attrNodeName: false,
    textNodeName : "#text",
    ignoreNonTextNodeAttr : true,
    ignoreTextNodeAttr : true,
    ignoreNameSpace : true,
    ignoreRootElement : false,
    textNodeConversion : true,
    textAttrConversion : false,
    arrayMode : false
};

if(parser.validate(xmlData)){//optional
    var jsonObj = parser.parse(xmlData, options);
}

//Intermediate obj
var tObj = parser.getTraversalObj(xmlData,options);
:
var jsonObj = parser.convertToJson(tObj);

Note: It doesn't use DOM parser but parse the string using RE and convert it into JS/JSON object.

Try it online, CDN

Simple you can use bellow class.

.nopadmar {_x000D_
   padding: 0 !important;_x000D_
   margin: 0 !important;_x000D_
}

<div class="container-fluid">_x000D_
  <div class="row">_x000D_
    <div class="col-md-6 nopadmar">Your Content<div>_x000D_
       <div class="col-md-6 nopadmar">Your Content<div>_x000D_
  </div>_x000D_
</div>

The simple answer is that arrays are ALWAYS passed by reference and the int arg[] simply lets the compiler know to expect an array

If you want to turn off app verification programmatically, you can do so with the following code:

boolean success = true;
boolean enabled = Settings.Secure.getInt(context.getContentResolver(), "package_verifier_enable", 1) == 1;
if (enabled) {
    success = Settings.Secure.putString(context.getContentResolver(), "package_verifier_enable", "0");
}

You will also need the following system permissions:

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

Also worth noting is that the "package_verifier_enable" string comes from the Settings.Glabal.PACKAGE_VERIFIER_ENABLE member which seems to be inaccessible.

$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

To understand get and set, it's all related to how variables are passed between different classes.

The get method is used to obtain or retrieve a particular variable value from a class.

A set value is used to store the variables.

The whole point of the get and set is to retrieve and store the data values accordingly.

What I did in this old project was I had a User class with my get and set methods that I used in my Server class.

The User class's get set methods:

public int getuserID()
    {
        //getting the userID variable instance
        return userID;
    }
    public String getfirstName()
    {
        //getting the firstName variable instance
        return firstName;
    }
    public String getlastName()
    {
        //getting the lastName variable instance
        return lastName;
    }
    public int getage()
    {
        //getting the age variable instance
        return age;
    }

    public void setuserID(int userID)
    {
        //setting the userID variable value
        this.userID = userID;
    }
    public void setfirstName(String firstName)
    {
        //setting the firstName variable text
        this.firstName = firstName;
    }
    public void setlastName(String lastName)
    {
        //setting the lastName variable text
        this.lastName = lastName;
    }
    public void setage(int age)
    {
        //setting the age variable value
        this.age = age;
    }
}

Then this was implemented in the run() method in my Server class as follows:

//creates user object
                User use = new User(userID, firstName, lastName, age);
                //Mutator methods to set user objects
                use.setuserID(userID);
                use.setlastName(lastName);
                use.setfirstName(firstName);               
                use.setage(age); 

Retype:

$ git config credential.helper store

And then you will be prompted to enter your credentials again.

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

Although your answer has many solutions I think this is a great way to save lines of code. Try using spans which is great for situations like yours.

1. Create a class for making any item bold. So for paragraph text it would be

span.bold(This name can be anything do not include parenthesis) {
   font-weight: bold;
}

1. In your html you can access that class like by using the span tags and adding a class of bold or whatever name you have chosen

See link Installation guide is in ...

https://gist.github.com/julionc/7476620

And run in terminal with this command

phantomjs --webdriver=4444

Old Timer Favorite (it still works):

List<String> list;

for(int i = list.size() - 1; i >= 0; --i) 
{
        if(list.get(i).contains("bad"))
        {
                list.remove(i);
        }
}

Benefits:

1. It only iterates over the list once
2. No extra objects created, or other unneeded complexity
3. No problems with trying to use the index of a removed item, because... well, think about it!

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

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

You can either use

<h:outputText value="#{param['id']}" /> or

<h:outputText value="#{request.getParameter('id')}" />

However if you want to pass the parameters to your backing beans, using f:viewParam is probably what you want. "A view parameter is a mapping between a query string parameter and a model value."

<f:viewParam name="id" value="#{blog.entryId}"/>

This will set the id param of the GET parameter to the blog bean's entryId field. See http://java.dzone.com/articles/bookmarkability-jsf-2 for the details.

Try this

myApp.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }
]);

Just setting useXDomain = true is not enough. AJAX request are also send with the X-Requested-With header, which indicate them as being AJAX. Removing the header is necessary, so the server is not rejecting the incoming request.

I have struggled with this for a long time, until I came across the cppreference.com explanation of the value categories.

It is actually rather simple, but I find that it is often explained in a way that's hard to memorize. Here it is explained very schematically. I'll quote some parts of the page:

Primary categories

The primary value categories correspond to two properties of expressions:

• has identity: it's possible to determine whether the expression refers to the same entity as another expression, such as by comparing addresses of the objects or the functions they identify (obtained directly or indirectly);

• can be moved from: move constructor, move assignment operator, or another function overload that implements move semantics can bind to the expression.

Expressions that:

• have identity and cannot be moved from are called lvalue expressions;
• have identity and can be moved from are called xvalue expressions;
• do not have identity and can be moved from are called prvalue expressions;
• do not have identity and cannot be moved from are not used.

lvalue

An lvalue ("left value") expression is an expression that has identity and cannot be moved from.

rvalue (until C++11), prvalue (since C++11)

A prvalue ("pure rvalue") expression is an expression that does not have identity and can be moved from.

xvalue

An xvalue ("expiring value") expression is an expression that has identity and can be moved from.

glvalue

A glvalue ("generalized lvalue") expression is an expression that is either an lvalue or an xvalue. It has identity. It may or may not be moved from.

rvalue (since C++11)

An rvalue ("right value") expression is an expression that is either a prvalue or an xvalue. It can be moved from. It may or may not have identity.

thanks for the ideas but none works here. So i did that... I am using xampp last version on 2014. go to \xampp\apache\conf\extra\httpd-xampp.conf.

we will find this bit of code:

<IfModule php5_module>
    **<FilesMatch "\.php$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

Focus on second line, so we must to change to:

<IfModule php5_module>
    **<FilesMatch "\.(php|html)$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

And that is it. Works good!

Another silly mistake you can do is copy recursive function from non class environment to class and don`t change inner self calls to $this->method_name()

i`m writing this because couldn`t understand why i got this error and this thread is first in google when you search for this error.

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

Exporting without default means it's a "named export". You can have multiple named exports in a single file. So if you do this,

class Template {}
class AnotherTemplate {}

export { Template, AnotherTemplate }

then you have to import these exports using their exact names. So to use these components in another file you'd have to do,

import {Template, AnotherTemplate} from './components/templates'

Alternatively if you export as the default export like this,

export default class Template {}

Then in another file you import the default export without using the {}, like this,

import Template from './components/templates'

There can only be one default export per file. In React it's a convention to export one component from a file, and to export it is as the default export.

You're free to rename the default export as you import it,

import TheTemplate from './components/templates'

And you can import default and named exports at the same time,

import Template,{AnotherTemplate} from './components/templates'

Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.

The query with the LIKE keyword showed a clustered index scan.

The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.

We can use an optional merger function also in case of same key collision. For example, If two or more persons have the same getLast() value, we can specify how to merge the values. If we not do this, we could get IllegalStateException. Here is the example to achieve this...

Map<String, Person> map = 
roster
    .stream()
    .collect(
        Collectors.toMap(p -> p.getLast(),
                         p -> p,
                         (person1, person2) -> person1+";"+person2)
    );

This query i have generated for inserting the Excel file data into database In this id and price are numeric values and date field as well. This query summarized all the type which I require It may useful to you as well

="insert into  product (product_id,name,date,price) values("&A1&",'" &B1& "','" &C1& "'," &D1& ");"


    Id    Name           Date           price 
    7   Product 7   2017-01-05 15:28:37 200
    8   Product 8   2017-01-05 15:28:37 40
    9   Product 9   2017-01-05 15:32:31 500
    10  Product 10  2017-01-05 15:32:31 30
    11  Product 11  2017-01-05 15:32:31 99
    12  Product 12  2017-01-05 15:32:31 25

This message will appear if you are using a case-insensitive file system (e.g. on a Mac) and you're trying to capitalize the name (or another change of case). In which case you need to rename to a third, dummy, name:

svn mv file-name file-name_
svn mv file-name_ FILE_Name
svn commit

I guess you may have already found the answer, but if not (and for other developers), you can do it like this:

btnMybutton.getBackground().setAlpha(45);

Here I have set the opacity to 45. You can basically set it from anything between 0(fully transparent) to 255 (completely opaque)

I think this sample explains the difference between the styles:

james@bodacious-wired:~$cat test.py 
#!/usr/bin/env python

class MyClass:
    element1 = "Hello"

    def __init__(self):
        self.element2 = "World"

obj = MyClass()

print dir(MyClass)
print "--"
print dir(obj)
print "--"
print obj.element1 
print obj.element2
print MyClass.element1 + " " + MyClass.element2
james@bodacious-wired:~$./test.py 
['__doc__', '__init__', '__module__', 'element1']
--
['__doc__', '__init__', '__module__', 'element1', 'element2']
--
Hello World
Hello
Traceback (most recent call last):
  File "./test.py", line 17, in <module>
    print MyClass.element2
AttributeError: class MyClass has no attribute 'element2'

element1 is bound to the class, element2 is bound to an instance of the class.

The problem is that you are using a lower case v.

You need to set it to Value and it should fix your issue:

@Html.TextBoxFor(model => model.Destination, new { id = "txtPlace", Value= "3" })

Another alternative is to download and install git from here. Then, add the path to Git\bin\ to your PATH variable. This will give you not only diff, but also many other linux commands that you can use from the windows command line.

You can set the PATH variable by right clicking on Computer and selecting Properties. Then you can click on Advanced System Settings on the left side of the screen. In the pop up, click Environment Variables and then either add or update the PATH variable in your user variables with Git\bin\

Git diff documentation

If the database has open connections, this script may help. I use this to create a test database from a backup of the live-production database every night. This assumes that you have an .SQL backup file from the production db (I do this within webmin).

#!/bin/sh

dbname="desired_db_name_of_test_enviroment"
username="user_name"
fname="/path to /ExistingBackupFileOfLive.sql"

dropdbcmp="DROP DATABASE $dbname"
createdbcmd="CREATE DATABASE $dbname WITH OWNER = $username "

export PGPASSWORD=MyPassword



echo "**********"
echo "** Dropping $dbname"
psql -d postgres -h localhost -U "$username" -c "$dropdbcmp"

echo "**********"
echo "** Creating database $dbname"
psql -d postgres -h localhost -U "$username" -c "$createdbcmd"

echo "**********"
echo "** Loading data into database"
psql -d postgres -h localhost -U "$username" -d "$dbname" -a -f "$fname"

end 2017 / 2018: the anothers answers have too much old code to edit, so here my alternative clean answer:

with require

let moment = require('moment');
require('moment/locale/fr.js');
// or if you want to include all locales:
require("moment/min/locales.min");

with imports

import moment from 'moment';
import 'moment/locale/fr';
// or if you want to include all locales:
require("moment/min/locales.min");

Use:

moment.locale('fr');
moment().format('D MMM YY');  // Correct, set default global format 
// moment.locale('fr').format('D MMM YY') //Wrong old versions for global default format

with timezone

*require:

require('moment-range');
require('moment-timezone');

*import:

import 'moment-range';
import 'moment-timezone';

use zones:

const newYork    = moment.tz("2014-06-01 12:00", "America/New_York");
const losAngeles = newYork.clone().tz("America/Los_Angeles");
const london     = newYork.clone().tz("Europe/London");

function to format date

const ISOtoDate = function (dateString, format='') {

 // if date is not string use conversion:
 // value.toLocaleDateString() +' '+ value.toLocaleTimeString();

  if ( !dateString ) {
    return '';
  }

  if (format ) {
    return moment(dateString).format(format);
  } else  {
    return moment(dateString);  // It will use default global format
  }  
};

I don't see any answer with reference to CSS flex property, but it can be very useful too.

This should be working. Please have a look at this fiddle.

$(function() {
   $( "#slider" ).slider();
});//Links to jsfiddle must be accompanied by code

Make sure you're loading the libraries in this order: jQuery, jQuery UI CSS, jQuery UI, AngularJS.

This worked for me

<img src="data:image;base64,@System.Convert.ToBase64String(Model.CategoryPicture.Content)" width="80" height="80"/>     

If i understand you correctly, (i probably don't)

'SELECT @RowCount = COUNT(*)
                   FROM dbo.Comm_Services
                   WHERE CompanyId = ' + CAST(@CompanyId AS CHAR) + '
                   AND ' + @condition

Like this:

numrows = len(input)    # 3 rows in your example
numcols = len(input[0]) # 2 columns in your example

Assuming that all the sublists have the same length (that is, it's not a jagged array).

Personally, I think the icons generated by the Google Charts API look great and are easy to customise dynamically.

I believe we can start from basic to achieve desired result.

For example, I had a situation to extract data after "/". The given excel field had a value of 2rko6xyda14gdl7/VEERABABU%20MATCHA%20IN131621.jpg . I simply wanted to extract the text from "I5" cell after slash symbol. So firstly I want to find where "/" symbol is (FIND("/",I5). This gives me the position of "/". Then I should know the length of text, which i can get by LEN(I5).so total length minus the position of "/" . which is LEN(I5)-(FIND("/",I5)) . This will first find the "/" position and then get me the total text that needs to be extracted. The RIGHT function is RIGHT(I5,12) will simply extract all the values of last 12 digits starting from right most character. So I will replace the above function "LEN(I5)-(FIND("/",I5))" for 12 number in the RIGHT function to get me dynamically the number of characters I need to extract in any given cell and my solution is presented as given below

The approach was

=RIGHT(I5,LEN(I5)-(FIND("/",I5))) will give me out as VEERABABU%20MATCHA%20IN131621.jpg . I think I am clear.

Here's a trick if you want constants and don't care their values:

Just define empty classes.

e.g:

class RED: 
    pass
class BLUE: 
    pass

These links explain it with examples

http://dotnetperls.com/openfiledialog

http://www.geekpedia.com/tutorial67_Using-OpenFileDialog-to-open-files.html

private void button1_Click(object sender, EventArgs e)
{
    int size = -1;
    DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
    if (result == DialogResult.OK) // Test result.
    {
       string file = openFileDialog1.FileName;
       try
       {
          string text = File.ReadAllText(file);
          size = text.Length;
       }
       catch (IOException)
       {
       }
    }
    Console.WriteLine(size); // <-- Shows file size in debugging mode.
    Console.WriteLine(result); // <-- For debugging use.
}

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

Works fine for me with this

    Calendar cal = Calendar.getInstance(TimeZone.getTimeZone());
    cal.set(Calendar.MONTH, month-1);  
    cal.set(Calendar.YEAR, year);  
    cal.add(Calendar.DATE, -1);  
    cal.set(Calendar.DAY_OF_MONTH, 
    cal.getActualMaximum(Calendar.DAY_OF_MONTH));
    cal.set(Calendar.HOUR_OF_DAY, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);
    return cal.getTimeInMillis();

I try all the above, if you did all steps in the above answers, and you not solve the problem, then:

1. on the left menu, hit the "Resources"
2. in the right to "Resources", hit the api method that you want to test, like "POST/GET etc)
3. hit the "ACTION" list (it's above to the API method in step 2
4. select "DEPLOY API" (please do it, even you already deploy yours api)
5. in "deployment stage" select "prod" or what ever you write in yours previous deploy (it will override yours previous deploy
6. hit deploy

I thing that because of, when I create the "METHOD REQUEST" (see step 2 how to go to this menu) , in "Authorization" I select "AWS_IAM" after testing api, in aws test option, I try it in "postman" then I understand the in "METHOD REQUEST" , in "Authorization", I should select "none"

I change it to none, but I thing the AWS, need to deploy it again, as I explain

You have two options,

-If you want the value:

Dim MyValue as Variant ' or string/date/long/...
MyValue = ThisWorkbook.Sheets(1).Range("A1").Value

-if you want the cell object:

Dim oCell as Range  ' or object (but then you'll miss out on intellisense), and both can also contain more than one cell.
Set oCell = ThisWorkbook.Sheets(1).Range("A1")

if [ -n "$PID" -a -e /proc/$PID ]; then
    echo "process exists"
fi

or

if [ -n "$(ps -p $PID -o pid=)" ]

In the latter form, -o pid= is an output format to display only the process ID column with no header. The quotes are necessary for non-empty string operator -n to give valid result.

I had a similar issue and the "nbextensions" pointed out by @Energya worked very well and effortlessly. The install instructions are straight forward (I tried with anaconda on Windows) for the notebook extensions and for their configurator.

That said, I would like to add that the following extensions should be of interest.

• Hide Input | This extension allows hiding of an individual codecell in a notebook. This can be achieved by clicking on the toolbar button:

• Collapsible Headings | Allows notebook to have collapsible sections, separated by headings

• Codefolding | This has been mentioned but I add it for completeness

Using river can present issues when your operation scales up. River will use a ton of memory when under heavy operation. I recommend implementing your own elasticsearch models, or if you're using mongoose you can build your elasticsearch models right into that or use mongoosastic which essentially does this for you.

Another disadvantage to Mongodb River is that you'll be stuck using mongodb 2.4.x branch, and ElasticSearch 0.90.x. You'll start to find that you're missing out on a lot of really nice features, and the mongodb river project just doesn't produce a usable product fast enough to keep stable. That said Mongodb River is definitely not something I'd go into production with. It's posed more problems than its worth. It will randomly drop write under heavy load, it will consume lots of memory, and there's no setting to cap that. Additionally, river doesn't update in realtime, it reads oplogs from mongodb, and this can delay updates for as long as 5 minutes in my experience.

We recently had to rewrite a large portion of our project, because its a weekly occurrence that something goes wrong with ElasticSearch. We had even gone as far as to hire a Dev Ops consultant, who also agrees that its best to move away from River.

UPDATE: Elasticsearch-mongodb-river now supports ES v1.4.0 and mongodb v2.6.x. However, you'll still likely run into performance problems on heavy insert/update operations as this plugin will try to read mongodb's oplogs to sync. If there are a lot of operations since the lock(or latch rather) unlocks, you'll notice extremely high memory usage on your elasticsearch server. If you plan on having a large operation, river is not a good option. The developers of ElasticSearch still recommend you to manage your own indexes by communicating directly with their API using the client library for your language, rather than using river. This isn't really the purpose of river. Twitter-river is a great example of how river should be used. Its essentially a great way to source data from outside sources, but not very reliable for high traffic or internal use.

Also consider that mongodb-river falls behind in version, as its not maintained by ElasticSearch Organization, its maintained by a thirdparty. Development was stuck on v0.90 branch for a long time after the release of v1.0, and when a version for v1.0 was released it wasn't stable until elasticsearch released v1.3.0. Mongodb versions also fall behind. You may find yourself in a tight spot when you're looking to move to a later version of each, especially with ElasticSearch under such heavy development, with many very anticipated features on the way. Staying up on the latest ElasticSearch has been very important as we rely heavily on constantly improving our search functionality as its a core part of our product.

All in all you'll likely get a better product if you do it yourself. Its not that difficult. Its just another database to manage in your code, and it can easily be dropped in to your existing models without major refactoring.

This should work:

$(".hit").click(function(){    
   var value=$(this).closest('tr').children('td:first').text();
   alert(value);    
});

Explanation:

• .closest('tr') gets the nearest ancestor that is a <tr> element (so in this case the row where the <a> element is in).
• .children('td:first') gets all the children of this element, but with the :first selector we reduce it to the first <td> element.
• .text() gets the text inside the element

As you can see from the other answers, there is more than only one way to do this.

I used just "save in zoom", in example:

.my_checkbox {
    width:5vw;
    height:5vh;
}

I know I'm a little late to the party, but I did want to throw some interjections. (I would have commented but not enough reputation points yet, so, here's a full answer).

This requires the latest version of VS Code, Azure Repo Extention, and Git to be installed.

Anyone looking to use the new VS Code (or using the preview like myself), when you go to the Settings (Still File -> Preferences -> Settings or CTRL+, ) you'll be looking under User Settings -> Extensions -> Azure Repos.

Then under Tfvc: Location you can paste the location of the executable.

For 2017 it'll be

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

Or for 2019 (Preview)

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

After adding the location, I closed my VS Code (not sure if this was needed) and went my git repo to copy the git URL.

After that, went back into VS Code went to the Command Palette (View -> Command Palette or CTRL+Shift+P) typed Git: Clone pasted my repo:

Selected the location for the repo to be stored. Next was an error that popped up. I proceeded to follow this video which walked me through clicking on the Team button with the exclamation mark on the bottom of your VS Code Screen

Then chose the new method of authentication

Copy by using CTRL+C and then press enter. Your browser will launch a page where you'll enter the code you copied (CTRL+V).

Click Continue

Log in with your Microsoft Credentials and you should see a change on the bottom bar of VS Code.

Cheers!

That's not a good practice and there is no mechanism to do that because of that. The right way to accomplish what you want is inheritance.

Take a look into the class documentation.

A little example:

class Employee(object):

    def __init__(self, age, sex, siblings=0):
        self.age = age
        self.sex = sex    
        self.siblings = siblings

    def born_on(self):    
        today = datetime.date.today()

        return today - datetime.timedelta(days=self.age*365)


class Boss(Employee):    
    def __init__(self, age, sex, siblings=0, bonus=0):
        self.bonus = bonus
        Employee.__init__(self, age, sex, siblings)

This way Boss has everything Employee has, with also his own __init__ method and own members.

You need to save the PID of the background process at the time you start it:

foo &
FOO_PID=$!
# do other stuff
kill $FOO_PID

You cannot use job control, since that is an interactive feature and tied to a controlling terminal. A script will not necessarily have a terminal attached at all so job control will not necessarily be available.

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

If your data is coming from a model you can do:

App\Http\Controller\SomeController

public function index(MyModel $model)
{
    return view('index', [
        'data' => $model->all()->toJson(),
    ]);
}

index.blade.php

@push('footer-scripts')
  <script>
    (function(global){
      var data = {!! $data !!};
      console.log(data);
      // [{..}]
    })(window);
  </script>
@endpush

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

I think that they should perform generally the same, but there are some differences. START is generally used to start applications or to start the default application for a given file type. That way if you START http://mywebsite.com it doesn't do START iexplore.exe http://mywebsite.com.

START myworddoc.docx would start Microsoft Word and open myworddoc.docx.CALL myworddoc.docx does the same thing... however START provides more options for the window state and things of that nature. It also allows process priority and affinity to be set.

In short, given the additional options provided by start, it should be your tool of choice.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
  [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
  [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
  [command/program] [parameters]

"title"     Title to display in window title bar.
path        Starting directory.
B           Start application without creating a new window. The
            application has ^C handling ignored. Unless the application
            enables ^C processing, ^Break is the only way to interrupt
            the application.
I           The new environment will be the original environment passed
            to the cmd.exe and not the current environment.
MIN         Start window minimized.
MAX         Start window maximized.
SEPARATE    Start 16-bit Windows program in separate memory space.
SHARED      Start 16-bit Windows program in shared memory space.
LOW         Start application in the IDLE priority class.
NORMAL      Start application in the NORMAL priority class.
HIGH        Start application in the HIGH priority class.
REALTIME    Start application in the REALTIME priority class.
ABOVENORMAL Start application in the ABOVENORMAL priority class.
BELOWNORMAL Start application in the BELOWNORMAL priority class.
NODE        Specifies the preferred Non-Uniform Memory Architecture (NUMA)
            node as a decimal integer.
AFFINITY    Specifies the processor affinity mask as a hexadecimal number.
            The process is restricted to running on these processors.

            The affinity mask is interpreted differently when /AFFINITY and
            /NODE are combined.  Specify the affinity mask as if the NUMA
            node's processor mask is right shifted to begin at bit zero.
            The process is restricted to running on those processors in
            common between the specified affinity mask and the NUMA node.
            If no processors are in common, the process is restricted to
            running on the specified NUMA node.
WAIT        Start application and wait for it to terminate.

I fixed this problem.The device system version is older then the sdk minSdkVersion? I just modified the minSdkVersion from android_L to 19 to target my nexus 4.4.4.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.2'
    }
}
apply plugin: 'com.android.application'

repositories {
    jcenter()
}

android {
    **compileSdkVersion 'android-L'** modified to 19
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.antwei.uiframework.ui"
        minSdkVersion 14
        targetSdkVersion 'L'
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    **compile 'com.android.support:support-v4:21.+'** modified to compile 'com.android.support:support-v4:20.0.0'
}

how to modified the value by ide. select file->Project Structure -> Facets -> android-gradle and then modified the compile Sdk Version from android_L to 19

sorry I don't have enough reputation to add pictures

for regular Joins, it doesn't. TableA join TableB will produce the same execution plan as TableB join TableA (so your C and D examples would be the same)

for left and right joins it does. TableA left Join TableB is different than TableB left Join TableA, BUT its the same than TableB right Join TableA

Renaming a worksheet manually in Excel, you hit a limit of 31 chars, so I'd suggest that that's a hard limit.

The alternative and easier solution that i also use is to create custom marker layout and convert it into a bitmap.

view_custom_marker.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/custom_marker_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/marker_mask">

    <ImageView
        android:id="@+id/profile_image"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_gravity="center_horizontal"
        android:contentDescription="@null"
        android:src="@drawable/avatar" />
</FrameLayout>

Convert this view into bitmap by using the code below

 private Bitmap getMarkerBitmapFromView(@DrawableRes int resId) {

        View customMarkerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.view_custom_marker, null);
        ImageView markerImageView = (ImageView) customMarkerView.findViewById(R.id.profile_image);
        markerImageView.setImageResource(resId);
        customMarkerView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
        customMarkerView.layout(0, 0, customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight());
        customMarkerView.buildDrawingCache();
        Bitmap returnedBitmap = Bitmap.createBitmap(customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight(),
                Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(returnedBitmap);
        canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN);
        Drawable drawable = customMarkerView.getBackground();
        if (drawable != null)
            drawable.draw(canvas);
        customMarkerView.draw(canvas);
        return returnedBitmap;
    }

Add your custom marker in on Map ready callback.

@Override
public void onMapReady(GoogleMap googleMap) {
    Log.d(TAG, "onMapReady() called with");
    mGoogleMap = googleMap;
    MapsInitializer.initialize(this);
    addCustomMarker();
}
private void addCustomMarker() {
    Log.d(TAG, "addCustomMarker()");
    if (mGoogleMap == null) {
        return;
    }

    // adding a marker on map with image from  drawable
   mGoogleMap.addMarker(new MarkerOptions()
            .position(mDummyLatLng)
            .icon(BitmapDescriptorFactory.fromBitmap(getMarkerBitmapFromView(R.drawable.avatar))));
}

For more details please follow the link below

How to create custom marker using layout?

Try using safe TryParseExact method

DateTime temp;
string   date = "2011-29-01 12:00 am";

DateTime.TryParseExact(date, "yyyy-dd-MM hh:mm tt", CultureInfo.InvariantCulture, DateTimeStyles.None, out temp);

I think this will bring it back using 3.0

The Accept Ranges header (the bit in writeHead()) is required for the HTML5 video controls to work.

I think instead of just blindly send the full file, you should first check the Accept Ranges header in the REQUEST, then read in and send just that bit. fs.createReadStream support start, and end option for that.

So I tried an example and it works. The code is not pretty but it is easy to understand. First we process the range header to get the start/end position. Then we use fs.stat to get the size of the file without reading the whole file into memory. Finally, use fs.createReadStream to send the requested part to the client.

var fs = require("fs"),
    http = require("http"),
    url = require("url"),
    path = require("path");

http.createServer(function (req, res) {
  if (req.url != "/movie.mp4") {
    res.writeHead(200, { "Content-Type": "text/html" });
    res.end('<video src="http://localhost:8888/movie.mp4" controls></video>');
  } else {
    var file = path.resolve(__dirname,"movie.mp4");
    fs.stat(file, function(err, stats) {
      if (err) {
        if (err.code === 'ENOENT') {
          // 404 Error if file not found
          return res.sendStatus(404);
        }
      res.end(err);
      }
      var range = req.headers.range;
      if (!range) {
       // 416 Wrong range
       return res.sendStatus(416);
      }
      var positions = range.replace(/bytes=/, "").split("-");
      var start = parseInt(positions[0], 10);
      var total = stats.size;
      var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
      var chunksize = (end - start) + 1;

      res.writeHead(206, {
        "Content-Range": "bytes " + start + "-" + end + "/" + total,
        "Accept-Ranges": "bytes",
        "Content-Length": chunksize,
        "Content-Type": "video/mp4"
      });

      var stream = fs.createReadStream(file, { start: start, end: end })
        .on("open", function() {
          stream.pipe(res);
        }).on("error", function(err) {
          res.end(err);
        });
    });
  }
}).listen(8888);

As everyone else is pointing out you should probably just pull and then merge the heads, but if you really want to get rid of your commits without any of the EditingHistory tools then you can just hg clone -r your repo to get all but those changes.

This doesn't delete them from the original repository, but it creates a new clone that doesn't have them. Then you can delete the repo you modified (if you'd like).

-background white -alpha remove -alpha off

Example:

convert image.png -background white -alpha remove -alpha off white.png

Feel free to replace white with any other color you want. Imagemagick documentation says this about the -alpha remove operation:

This operation is simple and fast, and does the job without needing any extra memory use, or other side effects that may be associated with alternative transparency removal techniques. It is thus the preferred way of removing image transparency.

The 8086 has a large family of instructions that accept a register operand and an effective address, perform some computations to compute the offset part of that effective address, and perform some operation involving the register and the memory referred to by the computed address. It was fairly simple to have one of the instructions in that family behave as above except for skipping that actual memory operation. Thus, the instructions:

mov ax,[bx+si+5]
lea ax,[bx+si+5]

were implemented almost identically internally. The difference is a skipped step. Both instructions work something like:

temp = fetched immediate operand (5)
temp += bx
temp += si
address_out = temp  (skipped for LEA)
trigger 16-bit read  (skipped for LEA)
temp = data_in  (skipped for LEA)
ax = temp

As for why Intel thought this instruction was worth including, I'm not exactly sure, but the fact that it was cheap to implement would have been a big factor. Another factor would have been the fact that Intel's assembler allowed symbols to be defined relative to the BP register. If fnord was defined as a BP-relative symbol (e.g. BP+8), one could say:

mov ax,fnord  ; Equivalent to "mov ax,[BP+8]"

If one wanted to use something like stosw to store data to a BP-relative address, being able to say

mov ax,0 ; Data to store
mov cx,16 ; Number of words
lea di,fnord
rep movs fnord  ; Address is ignored EXCEPT to note that it's an SS-relative word ptr

was more convenient than:

mov ax,0 ; Data to store
mov cx,16 ; Number of words
mov di,bp
add di,offset fnord (i.e. 8)
rep movs fnord  ; Address is ignored EXCEPT to note that it's an SS-relative word ptr

Note that forgetting the world "offset" would cause the contents of location [BP+8], rather than the value 8, to be added to DI. Oops.

This method works in 2.x as long as each element in the list is only a single digit. But you shouldn't actually use this. It's horrible.

>>> magic = lambda l:int(`l`[1::3])
>>> magic([3,1,3,3,7])

This is an old question and I'm not sure if the solution I'm going to mention was available by the time you asked, but I think it's worth mentioning. You can achieve what you want by adding a filter to nav_menu_submenu_css_class. See the example below - you can replace my-new-submenu-class by the class(es) you want:

function my_nav_menu_submenu_css_class( $classes ) {
    $classes[] = 'my-new-submenu-class';
    return $classes;
}
add_filter( 'nav_menu_submenu_css_class', 'my_nav_menu_submenu_css_class' );

Register the EventEmitter in your child component as the @Output:

@Output() onDatePicked = new EventEmitter<any>();

Emit value on click:

public pickDate(date: any): void {
    this.onDatePicked.emit(date);
}

Listen for the events in your parent component's template:

<div>
    <calendar (onDatePicked)="doSomething($event)"></calendar>
</div>

and in the parent component:

public doSomething(date: any):void {
    console.log('Picked date: ', date);
}

It's also well explained in the official docs: Component interaction.

Go to Nuget package manager and download Nunit Adapter as follow.

Using sshpass works best. To just include your password in scp use the ' ':

scp user1:'password'@xxx.xxx.x.5:sys_config /var/www/dev/

You can do this as well. Can be faster for quick calculations:

echo $[2+2]

Gson 1.6 now includes a low-level streaming API and a new parser which is actually faster than Jackson.

You just need one line:

ImageViewer1.Source = new BitmapImage(new Uri(@"\myserver\folder1\Customer Data\sample.png"));

\\. is the simple answer. Here is simple code for your help.

while (line != null) {
    //             
    String[] words = line.split("\\.");
    wr = "";
    mean = "";
    if (words.length > 2) {
        wr = words[0] + words[1];
        mean = words[2];

    } else {
        wr = words[0];
        mean = words[1];
    }
}
