A better, more modern, answer to this question is to use the %pip magic, like:

%pip install scipy

That will automatically use the correct Python version. Using !pip might be tied to a different version of Python, and then you might not find the package after installing it.

And in colab, the magic gives a nice message and button if it detects that you need to restart the runtime if pip updated a packaging you have already imported.

BTW, there is also a %conda magic for doing the same with conda.

You've got the right idea, but for /f is designed to work on multi-line files or commands, not individual strings.

In its simplest form, for is like Perl's for, or every other language's foreach. You pass it a list of tokens, and it iterates over them, calling the same command each time.

for %a in (hello world) do @echo %a

The extensions merely provide automatic ways of building the list of tokens. The reason your current code is coming up with nothing is that ';' is the default end of line (comment) symbol. But even if you change that, you'd have to use %%g, %%h, %%i, ... to access the individual tokens, which will severely limit your batch file.

The closest you can get to what you ask for is:

set TabbedPath=%PATH:;= %
for %%g in (%TabbedPath%) do echo %%g

But that will fail for quoted paths that contain semicolons.

In my experience, for /l and for /r are good for extending existing commands, but otherwise for is extremely limited. You can make it slightly more powerful (and confusing) with delayed variable expansion (cmd /v:on), but it's really only good for lists of filenames.

I'd suggest using WSH or PowerShell if you need to perform string manipulation. If you're trying to write whereis for Windows, try where /?.

== operator compares two object references to check whether they refer to same instance. This also, will return true on successful match.for example

public class Example{
public static void main(String[] args){
String s1 = "Java";
String s2 = "Java";
String s3 = new string ("Java");
test(Sl == s2)     //true
test(s1 == s3)      //false
}}

above example == is a reference comparison i.e. both objects point to the same memory location

String equals() is evaluates to the comparison of values in the objects.

   public class EqualsExample1{
   public static void main(String args[]){
   String s = "Hell";
   String s1 =new string( "Hello");
   String s2 =new string( "Hello");
   s1.equals(s2);    //true
    s.equals(s1) ;   //false
    }}

above example It compares the content of the strings. It will return true if string matches, else returns false.

Adding class using element's classList property:

element.classList.add('my-class-name');

Removing:

element.classList.remove('my-class-name');

I suppose repr function can help you:

s = 't\n'
repr(s)
"'t\\n'"
repr(s)[1:-1]
't\\n'

you can use $.param to assign data :

 $http({
  url: "http://example.appspot.com/rest/app",
  method: "POST",
  data: $.param({"foo":"bar"})
  }).success(function(data, status, headers, config) {
   $scope.data = data;
  }).error(function(data, status, headers, config) {
   $scope.status = status;
 });

• Open the PDF in MacOS´ Preview App
• Chose File menu –> Export as PDF
• In the export dialog klick the Details button an select your page size
• Click save

All pages of the resulting document will be scaled to that size. The resulting file size is nearly identical to the original PDF, so I conclude, that image resolutions/compressions are not changed.

Hints:

1. I am not sure whether the "Export as PDF" menu item is available by default or only if Adobe Acrobat is installed.

2. My first trial was to use Preview App and print (!) into a new PDF, but this leads to additional margins around the page content.

I think this is the kind of question only a core developer could/should answer. I've researched and found the core ticket #17048: URLs delivered to the browser should be root-relative. Where we can find the reasons explained by Andrew Nacin, lead core developer. He also links to this [wp-hackers] thread. On both those links, these are the key quotes on why WP doesn't use relative URLs:

Core ticket:

• Root-relative URLs aren't really proper. /path/ might not be WordPress, it might be outside of the install. So really it's not much different than an absolute URL.

• Any relative URLs also make it significantly more difficult to perform transformations when the install is moved. The find-replace is going to be necessary in most situations, and having an absolute URL is ironically more portable for those reasons.

• absolute URLs are needed in numerous other places. Needing to add these in conditionally will add to processing, as well as introduce potential bugs (and incompatibilities with plugins).

[wp-hackers] thread

• Relative to what, I'm not sure, as WordPress is often in a subdirectory, which means we'll always need to process the content to then add in the rest of the path. This introduces overhead.

• Keep in mind that there are two types of relative URLs, with and without the leading slash. Both have caveats that make this impossible to properly implement.

• WordPress should (and does) store absolute URLs. This requires no pre-processing of content, no overhead, no ambiguity. If you need to relocate, it is a global find-replace in the database.

And, on a personal note, more than once I've found theme and plugins bad coded that simply break when WP_CONTENT_URL is defined.
They don't know this can be set and assume that this is true: WP.URL/wp-content/WhatEver, and it's not always the case. And something will break along the way.

The plugin Relative URLs (linked in edse's Answer), applies the function wp_make_link_relative in a series of filters in the action hook template_redirect. It's quite a simple code and seems a nice option.

Column letter from column number can be extracted using formula by following steps
1. Calculate the column address using ADDRESS formula
2. Extract the column letter using MID and FIND function

Example:
1. ADDRESS(1000,1000,1)
results $ALL$1000
2. =MID(F15,2,FIND("$",F15,2)-2)
results ALL asuming F15 contains result of step 1

In one go we can write
MID(ADDRESS(1000,1000,1),2,FIND("$",ADDRESS(1000,1000,1),2)-2)

U can use javascript to achive that like this:

    this.clientContext = new SP.ClientContext.get_current();
    this.oWeb = clientContext.get_web();
    currentUser = this.oWeb.get_currentUser();  
    this.clientContext.load(currentUser);
      completefunc:this.clientContext.executeQueryAsync(Function.createDelegate(this,this.onQuerySucceeded), Function.createDelegate(this,this.onQueryFailed));


}

//U must set a timeout to recivie the exactly user u want:

function onQuerySucceeded(sender, args) {

    window.setTimeout("ttt();",1000);
}
function onQueryFailed(sender, args) {

    console.log(args.get_message());
}

//By using a proper timeout, u can get current user :

function ttt(){ 

    var clientContext = new SP.ClientContext.get_current();
    var groupCollection = clientContext.get_web().get_siteGroups();
    visitorsGroup = groupCollection.getByName('OLAP Portal Members');

    t=this.currentUser .get_loginName().toLowerCase();

    console.log ('this.currentUser .get_loginName() : '+ t);

/!\ socket.gethostbyname is depricated, prefer socket.getaddrinfo

from man gethostbyname:

The gethostbyname*(), gethostbyaddr*(), [...] functions are obsolete. Applications should use getaddrinfo(3), getnameinfo(3),

You need to add the python.exe in C://.../Anaconda3 installation file as well as C://.../Anaconda3/Scripts to PATH.

First go to your installation directory, in my case it is installed in C://Users/user/Anaconda3 and shift+right click and press "Open command window here" or it might be "Open powershell here", if it is powershell, just write cmd and hit enter to run command window. Then run the following command setx PATH %cd%

Then go to C://Users/user/Anaconda3/Scripts and open the command window there as above, then run the same command "setx PATH %cd%"

If you don't care about the difference between an unset variable or a variable with an empty value, you can use the default-value parameter expansion:

foo=${DEPLOY_ENV:-default}

If you do care about the difference, drop the colon

foo=${DEPLOY_ENV-default}

You can also use the -v operator to explicitly test if a parameter is set.

if [[ ! -v DEPLOY_ENV ]]; then
    echo "DEPLOY_ENV is not set"
elif [[ -z "$DEPLOY_ENV" ]]; then
    echo "DEPLOY_ENV is set to the empty string"
else
    echo "DEPLOY_ENV has the value: $DEPLOY_ENV"
fi

Memory in SunHotSpot JVM is organized into three generations: young generation, old generation and permanent generation.

• Young Generation : the newly created objects are allocated to the young gen.
• Old Generation : If the new object requests for a larger heap space, it gets allocated directly into the old gen. Also objects which have survived a few GC cycles gets promoted to the old gen i.e long lived objects house in old gen.
• Permanent Generation : The permanent generation holds objects that the JVM finds convenient to have the garbage collector manage, such as objects describing classes and methods, as well as the classes and methods themselves.

FYI: The permanent gen is not considered a part of the Java heap.

How does the three generations interact/relate to each other? Objects(except the large ones) are first allocated to the young generation. If an object remain alive after x no. of garbage collection cycles it gets promoted to the old/tenured gen. Hence we can say that the young gen contains the short lived objects while the old gen contains the objects having a long life. The permanent gen does not interact with the other two generations.

You would basically want something along the lines of:

SELECT e.*, v.Score
  FROM Evaluation e
LEFT JOIN Value v
ON v.CaseNum = e.CaseNum AND
v.FileNum = e.FileNum AND
v.ActivityNum = e.ActivityNum;

In C++11, you can do this as a one-liner with a call to regex_replace:

#include <string>
#include <regex>

using std::string;

string do_replace( string const & in, string const & from, string const & to )
{
  return std::regex_replace( in, std::regex(from), to );
}

string test = "Remove all spaces";
std::cout << do_replace(test, " ", "") << std::endl;

output:

From the Javadoc:

Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those the current class.

In the tutorial the todo.all returns a callback object. This is required for the router.get syntax.

From the documentation:

router.METHOD(path, [callback, ...] callback)

The router.METHOD() methods provide the routing functionality in Express, where METHOD is one of the HTTP methods, such as GET, PUT, POST, and so on, in lowercase. Thus, the actual methods are router.get(), router.post(), router.put(), and so on.

You still need to define the array of callback objects in your todo files so you can access the proper callback object for your router.

You can see from your tutorial that todo.js contains the array of callback objects (this is what you are accessing when you write todo.all):

module.exports = {
    all: function(req, res){
        res.send('All todos')
    },
    viewOne: function(req, res){
        console.log('Viewing ' + req.params.id);
    },
    create: function(req, res){
        console.log('Todo created')
    },
    destroy: function(req, res){
        console.log('Todo deleted')
    },
    edit: function(req, res){
        console.log('Todo ' + req.params.id + ' updated')
    }
};

Make children divs inline-block and they will position side by side:

#content {
   width: 500px;
   height: 500px;
}

#left, #right {
    display: inline-block;
    width: 45%;
    height: 100%;
}

You have added vendor/plugins/open_flash_chart_2 as “gitlink” entry, but never defined it as a submodule. Effectively you are using the internal feature that git submodule uses (gitlink entries) but you are not using the submodule feature itself.

You probably did something like this:

git clone git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2
git add vendor/plugins/open_flash_chart_2

This last command is the problem. The directory vendor/plugins/open_flash_chart_2 starts out as an independent Git repository. Usually such sub-repositories are ignored, but if you tell git add to explicitly add it, then it will create an gitlink entry that points to the sub-repository’s HEAD commit instead of adding the contents of the directory. It might be nice if git add would refuse to create such “semi-submodules”.

Normal directories are represented as tree objects in Git; tree objects give names, and permissions to the objects they contain (usually other tree and blob objects—directories and files, respectively). Submodules are represented as “gitlink” entries; gitlink entries only contain the object name (hash) of the HEAD commit of the submodule. The “source repository” for a gitlink’s commit is specified in the .gitmodules file (and the .git/config file once the submodule has been initialized).

What you have is an entry that points to a particular commit, without recording the source repository for that commit. You can fix this by either making your gitlink into a proper submodule, or by removing the gitlink and replacing it with “normal” content (plain files and directories).

Turn It into a Proper Submodule

The only bit you are missing to properly define vendor/plugins/open_flash_chart_2 as a submodule is a .gitmodules file. Normally (if you had not already added it as bare gitlink entry), you would just use git submodule add:

git submodule add git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2

As you found, this will not work if the path already exists in the index. The solution is to temporarily remove the gitlink entry from the index and then add the submodule:

git rm --cached vendor/plugins/open_flash_chart_2
git submodule add git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2

This will use your existing sub-repository (i.e. it will not re-clone the source repository) and stage a .gitmodules file that looks like this:

[submodule "vendor/plugins/open_flash_chart_2"]
    path = vendor/plugins/open_flash_chart_2
    url = git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2

It will also make a similar entry in your main repository’s .git/config (without the path setting).

Commit that and you will have a proper submodule. When you clone the repository (or push to GitHub and clone from there), you should be able to re-initialize the submodule via git submodule update --init.

Replace It with Plain Content

The next step assumes that your sub-repository in vendor/plugins/open_flash_chart_2 does not have any local history that you want to preserve (i.e. all you care about is the current working tree of the sub-repository, not the history).

If you have local history in the sub-repository that you care about, then you should backup the sub-repository’s .git directory before deleting it in the second command below. (Also consider the git subtree example below that preserves the history of the sub-repository’s HEAD).

git rm --cached vendor/plugins/open_flash_chart_2
rm -rf vendor/plugins/open_flash_chart_2/.git # BACK THIS UP FIRST unless you are sure you have no local changes in it
git add vendor/plugins/open_flash_chart_2

This time when adding the directory, it is not a sub-repository, so the files will be added normally. Unfortunately, since we deleted the .git directory there is no super-easy way to keep things up-to-date with the source repository.

You might consider using a subtree merge instead. Doing so will let you easily pull in changes from the source repository while keeping the files “flat” in your repository (no submodules). The third-party git subtree command is a nice wrapper around the subtree merge functionality.

git rm --cached vendor/plugins/open_flash_chart_2
git commit -m'converting to subtree; please stand by'
mv vendor/plugins/open_flash_chart_2 ../ofc2.local
git subtree add --prefix=vendor/plugins/open_flash_chart_2 ../ofc2.local HEAD
#rm -rf ../ofc2.local # if HEAD was the only tip with local history

Later:

git remote add ofc2 git://github.com/korin/open_flash_chart_2_plugin.git
git subtree pull --prefix=vendor/plugins/open_flash_chart_2 ofc2 master

git subtree push --prefix=vendor/plugins/open_flash_chart_2 [email protected]:me/my_ofc2_fork.git changes_for_pull_request

git subtree also has a --squash option that lets you avoid incorporating the source repository’s history into your history but still lets you pull in upstream changes.

document.location.constructor === window.location.constructor is true.

It's because it's exactly the same object as you can see from document.location===window.location.

So there's no need to compare the constructor or any other property.

Actually, on 32-bit computers a word is 32-bit, but the DWORD type is a leftover from the good old days of 16-bit.

In order to make it easier to port programs to the newer system, Microsoft has decided all the old types will not change size.

You can find the official list here: http://msdn.microsoft.com/en-us/library/aa383751(VS.85).aspx

All the platform-dependent types that changed with the transition from 32-bit to 64-bit end with _PTR (DWORD_PTR will be 32-bit on 32-bit Windows and 64-bit on 64-bit Windows).

As the documentation states, 'replace' determines whether the current element is replaced by the directive. The other option is whether it is just added to as a child basically. If you look at the source of your plnkr, notice that for the second directive where replace is false that the div tag is still there. For the first directive it is not.

First result:

<span myd1="">directive template1</span>

Second result:

<div myd2=""><span>directive template2</span></div>

This is commonly reported as an error due to using the wrong version of SSMS(Sql Server Management Studio). Use the version designed for your database version. You can use the command select @@version to check which version of sql server you are actually using. This version is reported in a way that is easier to interpret than that shown in the Help About in SSMS.

Using a newer version of SSMS than your database is generally error-free, i.e. backward compatible.

date() itself is only for formatting, but it accepts a second parameter.

date("F j, Y", time() - 60 * 60 * 24);

To keep it simple I just subtract 24 hours from the unix timestamp.

A modern oop-approach is using DateTime

$date = new DateTime();
$date->sub(new DateInterval('P1D'));
echo $date->format('F j, Y') . "\n";

Or in your case (more readable/obvious)

$date = new DateTime();
$date->add(DateInterval::createFromDateString('yesterday'));
echo $date->format('F j, Y') . "\n";

(Because DateInterval is negative here, we must add() it here)

If you are using Linux OS:

1. Remove matplotlib==1.3.1 from requirements.txt
2. Try to install with sudo apt-get install python-matplotlib
3. Run pip install -r requirements.txt (Python 2), or pip3 install -r requirements.txt (Python 3)
4. pip freeze > requirements.txt

If you are using Windows OS:

1. python -m pip install -U pip setuptools
2. python -m pip install matplotlib

Try to organize by folder:

baseTypes.ts

export class Animal {

}

export class Plant {
    photosynthesize() { /* ... */ }
}

import b = require('./baseTypes');

export class Dog extends b.Animal {
    woof() { }
}   

tree.ts

import b = require('./baseTypes');

class Tree extends b.Plant {
}

LivingThings.ts

import dog = require('./dog')
import tree = require('./tree')

export = {
    dog: dog,
    tree: tree
}

main.ts

import LivingThings = require('./LivingThings');
console.log(LivingThings.Tree)
console.log(LivingThings.Dog)

The idea is that your module themselves shouldn't care / know they are participating in a namespace, but this exposes your API to the consumer in a compact, sensible way which is agnostic to which type of module system you are using for the project.

At least for the GitHub Flavoured Markdown, you can give the illusion by making all the non-header row entries bold with the regular __ or ** formatting:

|Regular | text | in header | turns bold |
|-|-|-|-|
| __So__ | __bold__ | __all__ | __table entries__ |
| __and__ | __it looks__ | __like a__ | __"headerless table"__ |

Here's a short one:

const base = new URL('/', location.href).href;

console.log(base);

Abstract example with clearer table and column names:

UPDATE tableName t1
INNER JOIN tableName t2 ON t2.ref_column = t1.ref_column
SET t1.column_to_update = t2.column_desired_value

As suggested by @Nico

Hope this help someone.

No, you cannot insert a div directly inside of a table. It is not correct html, and will result in unexpected output.

I would be happy to be more insightful, but you haven't said what you are attempting, so I can't really offer an alternative.

you can use JsonConvert.SerializeObject()

JsonConvert.SerializeObject(myObject) // myObject is returned by JObject.Parse() method

JsonConvert.SerializeObject()

JObject.Parse()

You could do something like this: order your table by e.g. CustomerID (using the AdventureWorks Sales.Customer sample table), and iterate over those customers using a WHILE loop:

-- define the last customer ID handled
DECLARE @LastCustomerID INT
SET @LastCustomerID = 0

-- define the customer ID to be handled now
DECLARE @CustomerIDToHandle INT

-- select the next customer to handle    
SELECT TOP 1 @CustomerIDToHandle = CustomerID
FROM Sales.Customer
WHERE CustomerID > @LastCustomerID
ORDER BY CustomerID

-- as long as we have customers......    
WHILE @CustomerIDToHandle IS NOT NULL
BEGIN
    -- call your sproc

    -- set the last customer handled to the one we just handled
    SET @LastCustomerID = @CustomerIDToHandle
    SET @CustomerIDToHandle = NULL

    -- select the next customer to handle    
    SELECT TOP 1 @CustomerIDToHandle = CustomerID
    FROM Sales.Customer
    WHERE CustomerID > @LastCustomerID
    ORDER BY CustomerID
END

That should work with any table as long as you can define some kind of an ORDER BY on some column.

Stream is just an abstraction (or a wrapper) over a physical stream of bytes. This physical stream is called the base stream. So there is always a base stream over which a stream wrapper is created and thus the wrapper is named after the base stream type ie FileStream, MemoryStream etc.

The advantage of the stream wrapper is that you get a unified api to interact with streams of any underlying type usb, file etc.

Why would you treat data as stream - because data chunks are loaded on-demand, we can inspect/process the data as chunks rather than loading the entire data into memory. This is how most of the programs deal with big files, for eg encrypting an OS image file.

Just add profile to session configuration before client call. boto3.session.Session(profile_name='YOUR_PROFILE_NAME').client('cloudwatch')

I'm using Windows 10 and had the same problem. I resolved it updating the VirtualBox to version 5.1.5. I hope it can help.

What should happen in the case of overflow? If you want it to just get to the bottom of the window, use absolute positioning:

div {
  position: absolute;
  top: 300px;
  bottom: 0px;
  left: 30px;
  right: 30px;
}

This will put the DIV 30px in from each side, 300px from the top of the screen, and flush with the bottom. Add an overflow:auto; to handle cases where the content is larger than the div.

I'm not aware of anything in the Python standard library (or elsewhere) that implements Dawson's AlmostEqual2sComplement function. If that's the sort of behaviour you want, you'll have to implement it yourself. (In which case, rather than using Dawson's clever bitwise hacks you'd probably do better to use more conventional tests of the form if abs(a-b) <= eps1*(abs(a)+abs(b)) + eps2 or similar. To get Dawson-like behaviour you might say something like if abs(a-b) <= eps*max(EPS,abs(a),abs(b)) for some small fixed EPS; this isn't exactly the same as Dawson, but it's similar in spirit.

I solved the issue by following this link

namespace System.Web.Mvc
{
public sealed class JsonDotNetValueProviderFactory : ValueProviderFactory
{
    public override IValueProvider GetValueProvider(ControllerContext controllerContext)
    {
        if (controllerContext == null)
            throw new ArgumentNullException("controllerContext");

        if (!controllerContext.HttpContext.Request.ContentType.StartsWith("application/json", StringComparison.OrdinalIgnoreCase))
            return null;

        var reader = new StreamReader(controllerContext.HttpContext.Request.InputStream);
        var bodyText = reader.ReadToEnd();

        return String.IsNullOrEmpty(bodyText) ? null : new DictionaryValueProvider<object>(JsonConvert.DeserializeObject<ExpandoObject>(bodyText, new ExpandoObjectConverter()), CultureInfo.CurrentCulture);
    }
}

}

protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);

        //Remove and JsonValueProviderFactory and add JsonDotNetValueProviderFactory
        ValueProviderFactories.Factories.Remove(ValueProviderFactories.Factories.OfType<JsonValueProviderFactory>().FirstOrDefault());
        ValueProviderFactories.Factories.Add(new JsonDotNetValueProviderFactory());
    }

FWIW, here is the Java code we use to validate email addresses. The Regexp's are very similar:

public static final Pattern VALID_EMAIL_ADDRESS_REGEX = 
    Pattern.compile("^[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,6}$", Pattern.CASE_INSENSITIVE);

public static boolean validate(String emailStr) {
        Matcher matcher = VALID_EMAIL_ADDRESS_REGEX.matcher(emailStr);
        return matcher.find();
}

Works fairly reliably.

There are lots of free tools that can do this.

I use PDFTK (a open source cross-platform command-line tool) for things like that.

I know this is really old, but if you are copying and pasting anyway, you can just use:

read.csv(readClipboard())

readClipboard() escapes the back-slashes for you. Just remember to make sure the ".csv" is included in your copy, perhaps with this:

read.csv(paste0(readClipboard(),'.csv'))

And if you really want to minimize your typing you can use some functions:

setWD <- function(){
  setwd(readClipboard())
}


readCSV <- function(){
  return(readr::read_csv(paste0(readClipboard(),'.csv')))
} 

#copy directory path
setWD()

#copy file name
df <- readCSV()

Have you tried os.mkdir?

You might also try this little code snippet:

mypath = ...
if not os.path.isdir(mypath):
   os.makedirs(mypath)

makedirs creates multiple levels of directories, if needed.

You can vertically align a floated element in a way which works on IE 6+. It doesn't need full table markup either. This method isn't perfectly clean - includes wrappers and there are a few things to be aware of e.g. if you have too much text outspilling the container - but it's pretty good.

Short answer: You just need to apply display: table-cell to an element inside the floated element (table cells don't float), and use a fallback with position: absolute and top for old IE.

Long answer: Here's a jsfiddle showing the basics. The important stuff summarized (with a conditional comment adding an .old-ie class):

    .wrap {
        float: left;
        height: 100px; /* any fixed amount */
    }
    .wrap2 {
        height: inherit;
    }
    .content {
        display: table-cell;
        height: inherit;
        vertical-align: middle;
    }

    .old-ie .wrap{
        position: relative;
    }
    .old-ie .wrap2 {
        position: absolute;
        top: 50%;
    }
    .old-ie .content {
        position: relative;
        top: -50%;
        display: block;
    }

Here's a jsfiddle that deliberately highlight the minor faults with this method. Note how:

• In standards browsers, content that exceeds the height of the wrapper element stops centering and starts going down the page. This isn't a big problem (probably looks better than creeping up the page), and can be avoided by avoiding content that is too big (note that unless I've overlooked something, overflow methods like overflow: auto; don't seem to work)
• In old IE, the content element doesn't stretch to fill the available space - the height is the height of the content, not of the container.

Those are pretty minor limitations, but worth being aware of.

Code and idea adapted from here

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

Open httpd.conf file in your text editor. Find this line:

and change it

After change, save it and restart apache.

string s= string.Empty

for (int i = 0; i < Chkboxlist.Items.Count; i++)

{

    if (Chkboxlist.Items[i].Selected)
    {
        s+= Chkboxlist.Items[i].Value + ";"; 
    }

}

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

for this question we can also use this method :

I created a container and set it the desired height of the view port (depending on the number of charts or chart specific sizes):

.graph-container {
width: 100%;
height: 30vh;
}

To be dynamic to screen sizes I set the container as follows:

*Small media devices specific styles*/
@media screen and (max-width: 800px) {
.graph-container {
        display: block;
        float: none;
        width: 100%;
        margin-top: 0px;
        margin-right:0px;
        margin-left:0px;
        height: auto;
    }
}

Of course very important (as have been referred to numerous times) set the following option properties of your chart:

options:{
    maintainAspectRatio: false,
    responsive: true,
}

It's easy,this is my solution using objects!

My POJO

public class Person implements Serializable{

    private String name;
    private int age;

    //get & set

}

Method Notification

  Person person = new Person();
  person.setName("david hackro");
  person.setAge(10);

    Intent notificationIntent = new Intent(this, Person.class);
    notificationIntent.putExtra("person",person);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.notification_icon)
                .setAutoCancel(true)
                .setColor(getResources().getColor(R.color.ColorTipografiaAdeudos))
                .setPriority(2)
                .setLargeIcon(bm)
                .setTicker(fotomulta.getTitle())
                .setContentText(fotomulta.getMessage())
                .setContentIntent(PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT))
                .setWhen(System.currentTimeMillis())
                .setContentTitle(fotomulta.getTicketText())
                .setDefaults(Notification.DEFAULT_ALL);

New Activity

 private Person person;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_notification_push);
    person = (Person) getIntent().getSerializableExtra("person");
}

Good Luck!!

In the header file define a base class:

class BaseClass {
public:
    BaseClass(params);
};

Then define a derived class as inheriting the BaseClass:

class DerivedClass : public BaseClass {
public:
    DerivedClass(params);
};

In the source file define the BaseClass constructor:

BaseClass::BaseClass(params)
{
     //Perform BaseClass initialization
}

By default the derived constructor only calls the default base constructor with no parameters; so in this example, the base class constructor is NOT called automatically when the derived constructor is called, but it can be achieved simply by adding the base class constructor syntax after a colon (:). Define a derived constructor that automatically calls its base constructor:

DerivedClass::DerivedClass(params) : BaseClass(params)
{
     //This occurs AFTER BaseClass(params) is called first and can
     //perform additional initialization for the derived class
}

The BaseClass constructor is called BEFORE the DerivedClass constructor, and the same/different parameters params may be forwarded to the base class if desired. This can be nested for deeper derived classes. The derived constructor must call EXACTLY ONE base constructor. The destructors are AUTOMATICALLY called in the REVERSE order that the constructors were called.

EDIT: There is an exception to this rule if you are inheriting from any virtual classes, typically to achieve multiple inheritance or diamond inheritance. Then you MUST explicitly call the base constructors of all virtual base classes and pass the parameters explicitly, otherwise it will only call their default constructors without any parameters. See: virtual inheritance - skipping constructors

You can also use the following code :

package com.agileinfotech.bsviewer.ldap;

import java.util.Hashtable;
import java.util.ResourceBundle;

import javax.naming.Context;
import javax.naming.NamingException;
import javax.naming.directory.DirContext;

public class LDAPLoginAuthentication {
    public LDAPLoginAuthentication() {

    }

    ResourceBundle resBundle = ResourceBundle.getBundle("settings");

    @SuppressWarnings("unchecked")
    public String authenticateUser(String username, String password) {
        String strUrl = "success";
        Hashtable env = new Hashtable(11);
        boolean b = false;
        String Securityprinciple = "cn=" + username + "," + resBundle.getString("UserSearch");
        env.put(Context.INITIAL_CONTEXT_FACTORY, resBundle.getString("InitialContextFactory"));
        env.put(Context.PROVIDER_URL, resBundle.getString("Provider_url"));
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, Securityprinciple);
        env.put(Context.SECURITY_CREDENTIALS, password);

        try {
            // Create initial context
            DirContext ctx = new InitialDirContext(env);
            // Close the context when we're done
            b = true;
            ctx.close();

        } catch (NamingException e) {
            b = false;
        } finally {
            if (b) {
                strUrl = "success";
            } else {
                strUrl = "failer";
            }
        }
        return strUrl;
    }
}

I am assuming that we are dealing with a JFrame? The visible portion in the content pane - you have to use jframe.getContentPane().setBackground(...);

in javascript return statement only used inside function block. if you try to use return statement inside independent if else block it trigger syntax error : Illegal return statement in JavaScript

Here is my example code to avoid such error :

<script type = 'text/javascript'>
(function(){
    var ss= 'no';
    if(getStatus(ss)){
        alert('Status return true');   
    }else{
        alert('Status return false'); 
    }

    function getStatus(ask){
        if(ask=='yes')
        {
        return true;     
        }
        else
        {
        return false;
        }
    }
})();
</script>

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

For me, when typing the url, a user accidentally used a / instead of a ? to start the query parameters

e.g.:

url.com/endpoint/parameter=SomeValue&otherparameter=Another+value

which should have been:

url.com/endpoint?parameter=SomeValue&otherparameter=Another+value

Nowadays, Java 8 allows for a one-line functional solution that is cleaner, faster, and a whole lot simpler than the accepted solution:

List<String> list = new ArrayList<>();
list.add("behold");
list.add("bend");
list.add("bet");
list.add("bear");
list.add("beat");
list.add("become");
list.add("begin");

List<String> matches = list.stream().filter(it -> it.contains("bea")).collect(Collectors.toList());

System.out.println(matches); // [bear, beat]

And even easier in Kotlin:

val matches = list.filter { it.contains("bea") }

Use database column nullble() in Laravel. You can choose the default value or nullable value in database.

If you want to select particular element use below code

var gridRowData = $("<your grid name>").data("kendoGrid");
var selectedItem = gridRowData.dataItem(gridRowData.select());
var quote = selectedItem["<column name>"];

When I tried these steps I kept getting error:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Then i looked at event viewer and saw this error:Unable to install counter strings because the SYSTEM\CurrentControlSet\Services\ASP.NET_64\Performance key could not be opened or accessed. The first DWORD in the Data section contains the Win32 error code.

To fix the issue i manually created following entry in registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Performance

and followed these steps:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

In my case i was missing dll in bin folder which was referenced in web.config file. So check whether you were using any setting in web.config but actually don't have dll.

Thanks

this code worked for me:

window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId');

I could get to your expected result just by doing this in mysql:

 SELECT id, min(record_date), other_cols 
  FROM mytable
  GROUP BY id

Does this work for you?

One more for loop variant, looks cleaner to me than one with enumerate():

for idx in range(len(list)):
    list[idx]=... # set a new value
    # some other code which doesn't let you use a list comprehension

For fixing this issue from Eclipse:

1) Add below dependency in Maven pom.xml and save the pom.xml file.

Dos commands in my batch file were running only when I type EXIT in command/DOS window. This problem solved when I removed CMD from batch file. No need of it.

I am very late to this but I want to mention that that new is actually unsafe in the Obj-C with Swift world. Swift will only create a default init method if you do not create any other initializer. Calling new on a swift class with a custom initializer will cause a crash. If you use alloc/init then the compiler will properly complain that init does not exist.

You can even add the size of the terms (indexed terms). Have a look at Elastic Search: how to see the indexed data

Unique Approach

(Will work for Dialog, Fragment, Even Util class etc...)

ApplicationContext.getInstance().toast("I am toast");

Add below code in Application class accordingly.

public class ApplicationContext extends Application {

private static ApplicationContext instance;

@Override
public void onCreate() {
    super.onCreate();
    instance = this;
}

public static void toast(String message) {
    Toast.makeText(getContext(), message, Toast.LENGTH_SHORT).show();
}
}

GitHub have changed their recommendation several times (example).

It appears that they currently recommend HTTPS because it is the easiest to set up on the widest range of networks and platforms, and by users who are new to all this.

There is no inherent flaw in SSH (if there was they would disable it) -- in the links below, you will see that they still provide details about SSH connections too:

1. HTTPS is less likely to be blocked by a firewall.

   https://help.github.com/articles/which-remote-url-should-i-use/

   The https:// clone URLs are available on all repositories, public and private. These URLs work everywhere--even if you are behind a firewall or proxy.

2. An HTTPS connection allows credential.helper to cache your password.

   https://help.github.com/articles/set-up-git

   Good to know: The credential helper only works when you clone an HTTPS repo URL. If you use the SSH repo URL instead, SSH keys are used for authentication. While we do not recommend it, if you wish to use this method, check out this guide for help generating and using an SSH key.

Is JSTL's join(), what you searched for?

<c:set var="myVar" value="${fn:join(myParams.items, ' ')}" />

Use Scalable DP

Although making a different layout for different screen sizes is theoretically a good idea, it can get very difficult to accommodate for all screen dimensions, and pixel densities. Having over 20+ different dimens.xml files as suggested in the above answers, is not easy to manage at all.

How To Use:

To use sdp:

1. Include implementation 'com.intuit.sdp:sdp-android:1.0.5' in your build.gradle,

2. Replace any dp value such as 50dp with a @dimen/50_sdp like so:

   <TextView
    android:layout_width="@dimen/_50sdp"
    android:layout_height="@dimen/_50sdp"
    android:text="Hello World!" />
   

How It Works:

sdp scales with the screen size because it is essentially a huge list of different dimens.xml for every possible dp value.

See It In Action:

Here it is on three devices with widely differing screen dimensions, and densities:

Note that the sdp size unit calculation includes some approximation due to some performance and usability constraints.

There have been previous answers that showed the trick. In essence:

• you must retain POSIXct types to take advantage of all the existing plotting functions

• if you want to 'overlay' several days worth on a single plot, highlighting the intra-daily variation, the best trick is too ...

• impose the same day (and month and even year if need be, which is not the case here)

which you can do by overriding the day-of-month and month components when in POSIXlt representation, or just by offsetting the 'delta' relative to 0:00:00 between the different days.

So with times and val as helpfully provided by you:

## impose month and day based on first obs
ntimes <- as.POSIXlt(times)    # convert to 'POSIX list type'
ntimes$mday <- ntimes[1]$mday  # and $mon if it differs too
ntimes <- as.POSIXct(ntimes)   # convert back

par(mfrow=c(2,1))
plot(times,val)   # old times
plot(ntimes,val)  # new times

yields this contrasting the original and modified time scales:

        }

    }

Note that you can also expand part of argument list:

myfun(1, *("foo", "bar"))

public function search()
{
    if (isset($_GET) && !empty($_GET))
    {
        $prepareQuery = '';
        foreach ($_GET as $key => $data)
        {
            if ($data)
            {
                $prepareQuery.=$key . ' = "' . $data . '" OR ';
            }
        }
        $query = substr($prepareQuery, 0, -3);
        if ($query)
            $model = Businesses::whereRaw($query)->get();
        else
            $model = Businesses::get();

        return view('pages.search', compact('model', 'model'));
    }
}

There is no such function; the easiest way to do this is to use a dict comprehension:

my_dictionary = {k: f(v) for k, v in my_dictionary.items()}

In python 2.7, use the .iteritems() method instead of .items() to save memory. The dict comprehension syntax wasn't introduced until python 2.7.

Note that there is no such method on lists either; you'd have to use a list comprehension or the map() function.

As such, you could use the map() function for processing your dict as well:

my_dictionary = dict(map(lambda kv: (kv[0], f(kv[1])), my_dictionary.iteritems()))

but that's not that readable, really.

For me

Adding this line

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>

Before this line.

<script id="microloader" type="text/javascript" src=".sencha/app/microloader/development.js"></script>

worked

>>> L1 = [2,3,4]
>>> L2 = [1,2]
>>> [i for i in L1 if i in L2]
[2]


>>> S1 = set(L1)
>>> S2 = set(L2)
>>> S1.intersection(S2)
set([2])

Both empty lists and empty sets are False, so you can use the value directly as a truth value.

Here is a way to change the owner on ALL DBS (excluding System)

To answer your question. I would say it's fairly common for applications to replace spaces in values that will be used in URLs. The reason for this is ussually to avoid the more difficult to read percent (URI) encoding that occurs.

Check out this wikipedia article about Percent-encoding.

The main difference is that a 8-bit PNG comprises a max. of 256 colours, like GIFs. PNG-24 is a lossless format and can contain up to 16 million colours.

Maybe you can create an array like this:

     var myList = new Array();
     myList.push('Hello');
     myList.push('bye');

     for (var i = 0; i < myList .length; i ++ ){
        window.console.log(myList[i]);
     }

I know I'm a little late tothe party but thisworks pretty neat (our professor gave it to us)

public static byte[] asBytes (String s) {                   
           String tmp;
           byte[] b = new byte[s.length() / 2];
           int i;
           for (i = 0; i < s.length() / 2; i++) {
             tmp = s.substring(i * 2, i * 2 + 2);
             b[i] = (byte)(Integer.parseInt(tmp, 16) & 0xff);
           }
           return b;                                            //return bytes
    }

If you are willing to make use of C++11 std::async and std::future for running your tasks, then you can utilize the wait_for function of std::future to check if the thread is still running in a neat way like this:

#include <future>
#include <thread>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    /* Run some task on new thread. The launch policy std::launch::async
       makes sure that the task is run asynchronously on a new thread. */
    auto future = std::async(std::launch::async, [] {
        std::this_thread::sleep_for(3s);
        return 8;
    });

    // Use wait_for() with zero milliseconds to check thread status.
    auto status = future.wait_for(0ms);

    // Print status.
    if (status == std::future_status::ready) {
        std::cout << "Thread finished" << std::endl;
    } else {
        std::cout << "Thread still running" << std::endl;
    }

    auto result = future.get(); // Get result.
}

If you must use std::thread then you can use std::promise to get a future object:

#include <future>
#include <thread>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    // Create a promise and get its future.
    std::promise<bool> p;
    auto future = p.get_future();

    // Run some task on a new thread.
    std::thread t([&p] {
        std::this_thread::sleep_for(3s);
        p.set_value(true); // Is done atomically.
    });

    // Get thread status using wait_for as before.
    auto status = future.wait_for(0ms);

    // Print status.
    if (status == std::future_status::ready) {
        std::cout << "Thread finished" << std::endl;
    } else {
        std::cout << "Thread still running" << std::endl;
    }

    t.join(); // Join thread.
}

Both of these examples will output:

Thread still running

This is of course because the thread status is checked before the task is finished.

But then again, it might be simpler to just do it like others have already mentioned:

#include <thread>
#include <atomic>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    std::atomic<bool> done(false); // Use an atomic flag.

    /* Run some task on a new thread.
       Make sure to set the done flag to true when finished. */
    std::thread t([&done] {
        std::this_thread::sleep_for(3s);
        done = true;
    });

    // Print status.
    if (done) {
        std::cout << "Thread finished" << std::endl;
    } else {
        std::cout << "Thread still running" << std::endl;
    }

    t.join(); // Join thread.
}

Edit:

There's also the std::packaged_task for use with std::thread for a cleaner solution than using std::promise:

#include <future>
#include <thread>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    // Create a packaged_task using some task and get its future.
    std::packaged_task<void()> task([] {
        std::this_thread::sleep_for(3s);
    });
    auto future = task.get_future();

    // Run task on new thread.
    std::thread t(std::move(task));

    // Get thread status using wait_for as before.
    auto status = future.wait_for(0ms);

    // Print status.
    if (status == std::future_status::ready) {
        // ...
    }

    t.join(); // Join thread.
}

function fetch_comments($ticket_id){
    $this->db->select('tbl_tickets_replies.comments, 
           tbl_users.username,tbl_roles.role_name');
    $this->db->where('tbl_tickets_replies.ticket_id',$ticket_id);
    $this->db->join('tbl_users','tbl_users.id = tbl_tickets_replies.user_id');
    $this->db->join('tbl_roles','tbl_roles.role_id=tbl_tickets_replies.role_id');
    return $this->db->get('tbl_tickets_replies');
}

This tutorial is a very good one for pandas slicing. Make sure you check it out. Onto some snippets... To slice a dataframe with a condition, you use this format:

>>> df[condition]

This will return a slice of your dataframe which you can index using iloc. Here are your examples:

1. Get first row where A > 3 (returns row 2)

   >>> df[df.A > 3].iloc[0]
   A    4
   B    6
   C    3
   Name: 2, dtype: int64
   

If what you actually want is the row number, rather than using iloc, it would be df[df.A > 3].index[0].

2. Get first row where A > 4 AND B > 3:

   >>> df[(df.A > 4) & (df.B > 3)].iloc[0]
   A    5
   B    4
   C    5
   Name: 4, dtype: int64
   

3. Get first row where A > 3 AND (B > 3 OR C > 2) (returns row 2)

   >>> df[(df.A > 3) & ((df.B > 3) | (df.C > 2))].iloc[0]
   A    4
   B    6
   C    3
   Name: 2, dtype: int64
   

Now, with your last case we can write a function that handles the default case of returning the descending-sorted frame:

>>> def series_or_default(X, condition, default_col, ascending=False):
...     sliced = X[condition]
...     if sliced.shape[0] == 0:
...         return X.sort_values(default_col, ascending=ascending).iloc[0]
...     return sliced.iloc[0]
>>> 
>>> series_or_default(df, df.A > 6, 'A')
A    5
B    4
C    5
Name: 4, dtype: int64

As expected, it returns row 4.

warning: the rabbit hole goes deep :).

I don't think emulator and simulator can be compared. Both mimic something, but are not part of the same scope of reasonning, they are not used in the same context.

In short: an emulator is designed to copy some features of the orginial and can even replace it in the real environment. A simulator is not desgined to copy the features of the original, but only to appear similar to the original to human beings. Without the features of the orginal, the simulator cannot replace it in the real environment.

An emulator is a device that mimics something close enough so that it can be substituted to the real thing. E.g you want a circuit to work like a ROM (read only memory) circuit, but also wants to adjust the content until it is what you want. You'll use a ROM emulator, a black box (likely to be CPU-based) with a physical and electrical interfaces compatible with the ROM you want to emulate. The emulator will be plugged into the device in place of the real ROM. The motherboard will not see any difference when working, but you will be able to change the emulated-ROM content easily. Said otherwise the emulator will act exactly as the actual thing in its motherboard context (maybe a little bit slower due to actual internal model) but there will be additional functions (like re-writing) visible only to the designer, out of the motherboard context. So emulator definition would be: something that mimic the original, has all of its functional features, can actually replace it to some extend in the real world, and may have additional features not visible in the normal context.

A simulator is used in another thinking context, e.g a plane simulator, a car simulator, etc. The simulation will take care only of some aspect of the actual thing, usually those related to how a human being will perceive and control it. The simulator will not perform the functions of the real stuff, and cannot be sustituted to it. The plane simulator will not fly or carry someone, it's not its purpose at all. The simulator is not intended to work, but to appear to the pilot somehow like the actual thing for purposes other than its normal ones, e.g. to allow ground training (including in unusual situations like all-engine failure). So simulator definition would be: something that can appear to human, to some extend, like the original, but cannot replace it for actual use. In addition the pilot will know that the simulator is a simulator.

I don't think we'll see any ROM simulator, because ROM are not interacting with human beings, nor we'll see any plane emulator, because planes cannot have a replacement performing the same functions in the real world.

In my view the model inside an emulator or a simulator can be anything, and has not to be similar to the model of the original. A ROM emulator model will likely be software instead of hardware, MS Flight Simulator cannot be more software than it is.

This comparison of both terms will contradict the currently selected answer (from Toybuilder) which puts the difference on the internal model, while my suggestion is that the difference is whether the fake can or cannot be used to perform the actual function in the actual world (to some accepted extend, indeed).

Note that the plane simulator will have also to simulate the earth, the sun, the wind, etc, which are not part of the plane, so a plane simulator will have to mimic some aspects of the plane, as well as the environment of the plane because it is not used in this actual environment, but in a training room.

This is a big difference with the emulator which emulates only the orginal, and its purpose is to be used in the environment of the original with no need to emulate it. Back to the plane context... what could be a plane emulator? Maybe a train that will connect two airports -- actually two plane steps -- carrying passengers, with stewardesses onboard, with car interior looking like an actual plane cabin, and with captain saying "ladies and gentlemen our altitude is currenlty 10 kms and the temperature at our destination is 24°C". Its benefit is difficult to see, hum...

As a conclusion, the emulator is a real thing intended to work, the simulator is a fake intended to trick the user.

Using Java 8 or above you can use an Optional and Java Streams.

So you can simply use the JdbcTemplate.queryForList() method, create a Stream and use Stream.findFirst() which will return the first value of the Stream or an empty Optional:

public Optional<String> test() {
    String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
    return jdbc.queryForList(sql, String.class)
            .stream().findFirst();
}

To improve the performance of the query you can append LIMIT 1 to your query, so not more than 1 item is transferred from the database.

We have improved our answer with detail explanation.Now it's more easy to understand about extension method

Extension method: It is a mechanism through which we can extend the behavior of existing class without using the sub classing or modifying or recompiling the original class or struct.

We can extend our custom classes ,.net framework classes etc.

Extension method is actually a special kind of static method that is defined in the static class.

As DateTime class is already taken above and hence we have not taken this class for the explanation.

Below is the example

//This is a existing Calculator class which have only one method(Add)

public class Calculator 
{
    public double Add(double num1, double num2)
    {
        return num1 + num2;
    }

}

// Below is the extension class which have one extension method.  
public static class Extension
{
    // It is extension method and it's first parameter is a calculator class.It's behavior is going to extend. 
    public static double Division(this Calculator cal, double num1,double num2){
       return num1 / num2;
    }   
}

// We have tested the extension method below.        
class Program
{
    static void Main(string[] args)
    {
        Calculator cal = new Calculator();
        double add=cal.Add(10, 10);
        // It is a extension method in Calculator class.
        double add=cal.Division(100, 10)

    }
}

Try this code my friend...

#include<stdio.h>
int main(){
   char *s1, *s2;
   char str[10];

   printf("type a string: ");
   scanf("%s", str);

   s1 = &str[0];
   s2 = &str[2];

   printf("%c\n", *s1);   //use %c instead of %s and *s1 which is the content of position 1
   printf("%c\n", *s2);   //use %c instead of %s and *s3 which is the content of position 1

   return 0;
}

Having read this question and the answers a couple of times, all I can do is assume that there's been quite a bit of editing going on, and my suspicion is that you've been given the incorrect answer based on not providing enough information. My clue comes from the use of br tag.

Apologies to Darryl. I read class="inline" as style="display: inline". You have the right answer, even if you do use semantically questionable class names ;-)

The miss use of br to provide structural layout rather than for textual layout is far too prevalent for my liking.

If you're wanting to put more than inline elements inside those divs then you should be floating those divs rather than making them inline.

Floated divs:

===== ======= ==   **** ***** ******   +++++ ++++
===== ==== =====   ******** ***** **   ++ +++++++
=== ======== ===   ******* **** ****   
===== ==== =====                       +++++++ ++
====== == ======

Inline divs:

====== ==== ===== ===== == ==== *** ******* ***** ***** 
**** ++++ +++ ++ ++++ ++ +++++++ +++ ++++

If you're after the former, then this is your solution and lose those br tags:

<div style="float: left;" >
  <p>block level content or <span>inline content</span>.</p>
  <p>block level content or <span>inline content</span>.</p>
</div>
<div style="float: left;" >
  <p>block level content or <span>inline content</span>.</p>
  <p>block level content or <span>inline content</span>.</p>
</div>
<div style="float: left;" >
  <p>block level content or <span>inline content</span>.</p>
  <p>block level content or <span>inline content</span>.</p>
</div>

note that the width of these divs is fluid, so feel free to put widths on them if you want to control the behavior.

Thanks, Steve

If you are trying to accessing config variable into controller than use

$this->config->item('{variable name which you define into config}');

If you are trying to accessing the config variable into outside the controller(helper/hooks) then use

$mms = get_instance();  
$mms->config->item('{variable which you define into config}');

You can use ax.figure.savefig():

import pandas as pd

s = pd.Series([0, 1])
ax = s.plot.hist()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in Philip Cloud's answer, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

To solve this issue more globally, here is another way using a directive:

import { Directive, HostListener, ElementRef } from "@angular/core";

@Directive({
  selector: "[hrefExternalUrl]"
})
export class HrefExternalUrlDirective {
  constructor(elementRef: ElementRef) {}

  @HostListener("click", ["$event"])
  onClick(event: MouseEvent) {
    event.preventDefault();

    let url: string = (<any>event.currentTarget).getAttribute("href");

    if (url && url.indexOf("http") === -1) {
      url = `//${url}`;
    }

    window.open(url, "_blank");
  }
}

then it's as simple as using it like this:

<a [href]="url" hrefExternalUrl> Link </a>

and don't forget to declare the directive in your module.

Here's a list of keycodes that includes a way to look them up interactively.

Neither one of GET and POST is inherently "more secure" than the other, just like neither one of fax and phone is "more secure" than the other. The various HTTP methods are provided so that you can choose the one which is most appropiate for the problem you're trying to solve. GET is more appropiate for idempotent queries while POST is more appropiate for "action" queries, but you can shoot yourself in the foot just as easily with any of them if you don't understand the security architecture for the application you're maintaining.

It's probably best if you read Chapter 9: Method Definitions of the HTTP/1.1 RFC to get an overall idea of what GET and POST were originally envisioned ot mean.

Input: 0 0.1 1000

=FIXED(E5,2)

Output: 0.00 0.10 1,000.00

=TEXT(E5,"0.00")

Output: 0.00 0.10 1000.00

Note: As you can see FIXED add a coma after a thousand, where TEXT does not.

Another (apparently older) option is to use the format: "document.nameOfTheForm.nameOfTheInput.value;" e.g. document.mainForm.rads.value;

document.mainForm.onclick = function(){_x000D_
    var radVal = document.mainForm.rads.value;_x000D_
    result.innerHTML = 'You selected: '+radVal;_x000D_
}

<form id="mainForm" name="mainForm">_x000D_
    <input type="radio" name="rads" value="1" />_x000D_
    <input type="radio" name="rads" value="2" />_x000D_
    <input type="radio" name="rads" value="3" />_x000D_
    <input type="radio" name="rads" value="4" />_x000D_
</form>_x000D_
<span id="result"></span>

You can refer to the element by its name within a form. Your original HTML does not contain a form element though.

Fiddle here (works in Chrome and Firefox): https://jsfiddle.net/Josh_Shields/23kg3tf4/1/

That is not possible. A function that has a non-void return type (even if it's Void) has to return a value. However you could add static methods to Action that allows you to "create" a Action:

interface Action<T, U> {
   U execute(T t);

   public static Action<Void, Void> create(Runnable r) {
       return (t) -> {r.run(); return null;};
   }

   public static <T, U> Action<T, U> create(Action<T, U> action) {
       return action;
   } 
}

That would allow you to write the following:

// create action from Runnable
Action.create(()-> System.out.println("Hello World")).execute(null);
// create normal action
System.out.println(Action.create((Integer i) -> "number: " + i).execute(100));

In PowerShell V2, @ is also the Splat operator.

PS> # First use it to create a hashtable of parameters:
PS> $params = @{path = "c:\temp"; Recurse= $true}
PS> # Then use it to SPLAT the parameters - which is to say to expand a hash table 
PS> # into a set of command line parameters.
PS> dir @params
PS> # That was the equivalent of:
PS> dir -Path c:\temp -Recurse:$true

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/

Check out the apache config files. For Debian/Ubuntu theyre in /etc/apache2/sites-available/ for RedHat/CentOS/etc they're in /etc/httpd/conf.d/. If you've just installed it, the file in there is probably named default.

Make sure that the config file in there is pointing to the correct folder and then make sure your scripts are located there.

The line you're looking for in those files is DocumentRoot /path/to/directory.

For a blank install, your php files most likely needs to be in /var/www/.

What you'll also need to do is find your php.ini file, probably located at /etc/php5/apache2/php.ini or /etc/php.ini and find the entry for display_errors and switch it to On.

To get the current Id on a View:

ViewContext.RouteData.Values["id"].ToString()

To get the current controller:

ViewContext.RouteData.Values["controller"].ToString() 

You could use the following query:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 
            ON table1.id IN (table2.user_one, table2.user_two)
WHERE   table2.user_one IS NULL;

Although, depending on your indexes on table2 you may find that two joins performs better:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 AS t1
            ON table1.id = t1.user_one
        LEFT JOIN table2 AS t2
            ON table1.id = t2.user_two
WHERE   t1.user_one IS NULL
AND     t2.user_two IS NULL;

You should override __repr__ or __unicode__ methods instead of using message, the args you provide when you construct the exception will be in the args attribute of the exception object.

According to CanIUse you should have it with multiple prefixes.

$('div').css({
    "-webkit-transform":"translate(100px,100px)",
    "-ms-transform":"translate(100px,100px)",
    "transform":"translate(100px,100px)"
  });?

Package organization or package structuring is usually a heated discussion. Below are some simple guidelines for package naming and structuring:

• Follow java package naming conventions
• Structure your packages according to their functional role as well as their business role
  • Break down your packages according to their functionality or modules. e.g. com.company.product.modulea
  • Further break down could be based on layers in your software. But don't go overboard if you have only few classes in the package, then it makes sense to have everything in the package. e.g. com.company.product.module.web or com.company.product.module.util etc.
  • Avoid going overboard with structuring, IMO avoid separate packaging for exceptions, factories, etc. unless there's a pressing need.
• If your project is small, keep it simple with few packages. e.g. com.company.product.model and com.company.product.util, etc.
• Take a look at some of the popular open source projects out there on Apache projects. See how they use structuring, for various sized projects.
• Also consider build and distribution when naming ( allowing you to distribute your api or SDK in a different package, see servlet api)

After a few experiments and trials you should be able to come up with a structuring that you are comfortable with. Don't be fixated on one convention, be open to changes.

TypeA[] array = (TypeA[]) a.toArray();

@BindView(R.id.checkbox_id) // if you are using Butterknife
CheckBox yourCheckBox;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity); 
    yourCheckBox = (CheckBox)findViewById(R.id.checkbox_id);// If your are not using Butterknife (the traditional way)

    yourCheckBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            yourObject.setYourProperty(yourCheckBox.isChecked()); //yourCheckBox.isChecked() is the method to know if the checkBox is checked
            Log.d(TAG, "onClick: yourCheckBox = " + yourObject.getYourProperty() );
        }
    });
}

Obviously you have to make your XML with the id of your checkbox :

<CheckBox
    android:id="@+id/checkbox_id"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Your label"
    />

So, the method to know if the check box is checked is : (CheckBox) yourCheckBox.isChecked() it returns true if the check box is checked.

myElement.innerText = myElement.textContent = "foo";

Edit (thanks to Mark Amery for the comment below): Only do it this way if you know beyond a reasonable doubt that no code will be relying on checking the existence of these properties, like (for example) jQuery does. But if you are using jQuery, you would probably just use the "text" function and do $('#myElement').text('foo') as some other answers show.

Built-in toLocaleDateString() does the job, but it will remove the leading 0s for the day and month, so we will get something like "1/9/1970", which is not perfect in my opinion. To get a proper format MM/DD/YYYY we can use something like:

new Date(dateString).toLocaleDateString('en-US', {
  day: '2-digit',
  month: '2-digit',
  year: 'numeric',
})

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

writexl, without Java requirement:

# install.packages("writexl")
library(writexl)
tempfile <- write_xlsx(iris)

For other future users who do not want to make their controllers asynchronous, or cannot access the HttpContext, or are using dotnet core (this answer is the first I found on Google trying to do this), the following worked for me:

[HttpPut("{pathId}/{subPathId}"),
public IActionResult Put(int pathId, int subPathId, [FromBody] myViewModel viewModel)
{

    var body = new StreamReader(Request.Body);
    //The modelbinder has already read the stream and need to reset the stream index
    body.BaseStream.Seek(0, SeekOrigin.Begin); 
    var requestBody = body.ReadToEnd();
    //etc, we use this for an audit trail
}

I agree with Mutanos and Alecio. Further, one can check as many identical method calls as possible (verifying the subsequent calls in the production code, the order of the verify's does not matter). Here is the code:

import static org.mockito.AdditionalMatchers.*;

    verify(mockObject).myMethod(aryEq(new byte[] { 0 }));
    verify(mockObject).myMethod(aryEq(new byte[] { 1, 2 }));

For those who using version 7.8.5, the Auto-indent settings is now located at "Settings" -> "Preferences..." -> "Auto-Completion".

The first button is always the default; it can't be changed. Whilst you can try to fix it up with JavaScript, the form will behave unexpectedly in a browser without scripting, and there are some usability/accessibility corner cases to think about. For example, the code linked to by Zoran will accidentally submit the form on Enter press in a <input type="button">, which wouldn't normally happen, and won't catch IE's behaviour of submitting the form for Enter press on other non-field content in the form. So if you click on some text in a <p> in the form with that script and press Enter, the wrong button will be submitted... especially dangerous if, as given in that example, the real default button is ‘Delete’!

My advice would be to forget about using scripting hacks to reassign defaultness. Go with the flow of the browser and just put the default button first. If you can't hack the layout to give you the on-screen order you want, then you can do it by having a dummy invisible button first in the source, with the same name/value as the button you want to be default:

<input type="submit" class="defaultsink" name="COMMAND" value="Save" />

.defaultsink {
    position: absolute; left: -100%;
}

(note: positioning is used to push the button off-screen because display: none and visibility: hidden have browser-variable side-effects on whether the button is taken as default and whether it's submitted.)

I've written a class that extends TextView and does this. It just uses measureText as you suggest. Basically it has a maximum text size and minimum text size (which can be changed) and it just runs through the sizes between them in decrements of 1 until it finds the biggest one that will fit. Not particularly elegant, but I don't know of any other way.

Here is the code:

import android.content.Context;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontFitTextView extends TextView {

    public FontFitTextView(Context context) {
        super(context);
        initialise();
    }

    public FontFitTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialise();
    }

    private void initialise() {
        testPaint = new Paint();
        testPaint.set(this.getPaint());
        //max size defaults to the intially specified text size unless it is too small
        maxTextSize = this.getTextSize();
        if (maxTextSize < 11) {
            maxTextSize = 20;
        }
        minTextSize = 10;
    }

    /* Re size the font so the specified text fits in the text box
     * assuming the text box is the specified width.
     */
    private void refitText(String text, int textWidth) { 
        if (textWidth > 0) {
            int availableWidth = textWidth - this.getPaddingLeft() - this.getPaddingRight();
            float trySize = maxTextSize;

            testPaint.setTextSize(trySize);
            while ((trySize > minTextSize) && (testPaint.measureText(text) > availableWidth)) {
                trySize -= 1;
                if (trySize <= minTextSize) {
                    trySize = minTextSize;
                    break;
                }
                testPaint.setTextSize(trySize);
            }

            this.setTextSize(trySize);
        }
    }

    @Override
    protected void onTextChanged(final CharSequence text, final int start, final int before, final int after) {
        refitText(text.toString(), this.getWidth());
    }

    @Override
    protected void onSizeChanged (int w, int h, int oldw, int oldh) {
        if (w != oldw) {
            refitText(this.getText().toString(), w);
        }
    }

    //Getters and Setters
    public float getMinTextSize() {
        return minTextSize;
    }

    public void setMinTextSize(int minTextSize) {
        this.minTextSize = minTextSize;
    }

    public float getMaxTextSize() {
        return maxTextSize;
    }

    public void setMaxTextSize(int minTextSize) {
        this.maxTextSize = minTextSize;
    }

    //Attributes
    private Paint testPaint;
    private float minTextSize;
    private float maxTextSize;

}

To much code, you can use it like this:

#include<array>
#include<functional>

int main()
{
    std::array<int, 10> vec = { 1,2,3,4,5,6,7,8,9 };

    std::sort(std::begin(vec), 
              std::end(vec), 
              [](int a, int b) {return a > b; });

    for (auto item : vec)
      std::cout << item << " ";

    return 0;
}

Replace "vec" with your class and that's it.

Have you tried setting JButton.setOpaque(true)?

JButton button = new JButton("test");
button.setBackground(Color.RED);
button.setOpaque(true);

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

For non-servers this requires Remote Server Administration Tools for Windows __

Following piece of code went easy on my dull brain. Removing the object and replacing with the updated one

    var udpateditem = this.state.items.find(function(item) { 
                   return item.name == "field_1" });
    udpateditem.name= "New updated name"                       
    this.setState(prevState => ({                                   
    items:prevState.dl_name_template.filter(function(item) { 
                                    return item.name !== "field_1"}).concat(udpateditem)
    }));

You can use a turn-around and just deploy the application into tomcat server: just copy/paste under the webapps folder. Once tomcat is started, it will create a folder with the app name and you can access the contents directly

You could probably use while loop instead of foreach:

while ($current = current($array) )
{
    $next = next($array);
    if (false !== $next && $next == $current)
    {
        //do something with $current
    }
}

If you're behind a proxy, you should use X-Forwarded-For: http://en.wikipedia.org/wiki/X-Forwarded-For

It is an IETF draft standard with wide support:

The X-Forwarded-For field is supported by most proxy servers, including Squid, Apache mod_proxy, Pound, HAProxy, Varnish cache, IronPort Web Security Appliance, AVANU WebMux, ArrayNetworks, Radware's AppDirector and Alteon ADC, ADC-VX, and ADC-VA, F5 Big-IP, Blue Coat ProxySG, Cisco Cache Engine, McAfee Web Gateway, Phion Airlock, Finjan's Vital Security, NetApp NetCache, jetNEXUS, Crescendo Networks' Maestro, Web Adjuster and Websense Web Security Gateway.

If not, here are a couple other common headers I've seen:

• X-Client-IP (Apache)
• X-Real-IP (Nginx)

From JPA 2.2, instead of .getResultList() and checking if list is empty or creating a stream you can return stream and take first element.

.getResultStream()
.findFirst()
.orElse(null);

<span style="margin-left:64px"></span>  

Consider it like this: one tab is equal to 64 pixels. So this is the space we can give by CSS.

Guid.NewGuid() will create one

input:focus {
    outline:none;
}

This will do. Orange outline won't show up anymore.

Step 1 : Delete .iml file

Step 2 : Check if your Project Directory Contain any white spaces if so then Rename your project directory leaving space

ex:

Before : My Project

After rename : MyProject

and open Android Studio...

You can try with filter hack:

.colorize-pink {
  filter: brightness(0.5) sepia(1) hue-rotate(-70deg) saturate(5);
}

.colorize-navy {
  filter: brightness(0.2) sepia(1) hue-rotate(180deg) saturate(5);
}

.colorize-blue {
  filter: brightness(0.5) sepia(1) hue-rotate(140deg) saturate(6);
}

For anyone looking for an answer to remove only the leading whitespaces out of a string (as the question title clearly ask), Here's an answer:

Assuming:

let string = "   Hello, World!   "

To remove all leading whitespaces, use the following code:

var filtered = ""
var isLeading = true
for character in string {
    if character.isWhitespace && isLeading {
        continue
    } else {
        isLeading = false
        filtered.append(character)
    }
}
print(filtered) // "Hello, World!   "

I'm sure there's better code than this, but it does the job for me.

This is the best format. Works in all of those cases:

String.Format( "{0:#,##0.##}", 0 ); // 0
String.Format( "{0:#,##0.##}", 0.5 ); // 0.5 - some of the formats above fail here. 
String.Format( "{0:#,##0.##}", 12314 ); // 12,314
String.Format( "{0:#,##0.##}", 12314.23123 ); // 12,314.23
String.Format( "{0:#,##0.##}", 12314.2 ); // 12,314.2
String.Format( "{0:#,##0.##}", 1231412314.2 ); // 1,231,412,314.2

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

You can iterate over the object to get the keys or values:

function numKeys(obj)
{
    var count = 0;
    for(var prop in obj)
    {
        count++;
    }
    return count;
}

It looks like a "spelling mistake" but just want to point out that your example is invalid syntax, should be

var object = {"key1":"value1","key2":"value2","key3":"value3"};

If ComboBox1.SelectedIndex = -1 Then
    ComboBox1.SelectedIndex = 0    
End If

Use this method:

Process.Start(String, String)

First argument is an application (explorer.exe), second method argument are arguments of the application you run.

For example:

in CMD:

explorer.exe -p

in C#:

Process.Start("explorer.exe", "-p")

You can create your own custom config section in the app.config file. There are quite a few tutorials around to get you started. Ultimately, you could have something like this:

<configSections>
    <section name="backupDirectories" type="TestReadMultipler2343.BackupDirectoriesSection, TestReadMultipler2343" />
  </configSections>

<backupDirectories>
   <directory location="C:\test1" />
   <directory location="C:\test2" />
   <directory location="C:\test3" />
</backupDirectories>

To complement Richard's answer, this is the C# you could use with his sample configuration:

using System.Collections.Generic;
using System.Configuration;
using System.Xml;

namespace TestReadMultipler2343
{
    public class BackupDirectoriesSection : IConfigurationSectionHandler
    {
        public object Create(object parent, object configContext, XmlNode section)
        {
            List<directory> myConfigObject = new List<directory>();

            foreach (XmlNode childNode in section.ChildNodes)
            {
                foreach (XmlAttribute attrib in childNode.Attributes)
                {
                    myConfigObject.Add(new directory() { location = attrib.Value });
                }
            }
            return myConfigObject;
        }
    }

    public class directory
    {
        public string location { get; set; }
    }
}

Then you can access the backupDirectories configuration section as follows:

List<directory> dirs = ConfigurationManager.GetSection("backupDirectories") as List<directory>;

In Mgmt Studio, when you are editing the top 200, you can view the SQL pane - either by right clicking in the grid and choosing Pane->SQL or by the button in the upper left. This will allow you to write a custom query to drill down to the row(s) you want to edit.

But ultimately mgmt studio isn't a data entry/update tool which is why this is a little cumbersome.

In new version of jquery, could done it via following steps:

• get param array via serializeArray()
• call push() or similar methods to add additional params to the array,
• call $.param(arr) to get serialized string, which could be used as jquery ajax's data param.

Example code:

var paramArr = $("#loginForm").serializeArray();
paramArr.push( {name:'size', value:7} );
$.post("rest/account/login", $.param(paramArr), function(result) {
    // ...
}

It's happened to me because I changed the Deployment Target in General but forgot to change the Deployment Target in Pods > General.

Without .join() method you can use this method:

my_list=["this","is","a","sentence"]

concenated_string=""
for string in range(len(my_list)):
    if string == len(my_list)-1:
        concenated_string+=my_list[string]
    else:
        concenated_string+=f'{my_list[string]}-'
print([concenated_string])
    >>> ['this-is-a-sentence']

So, range based for loop in this example , when the python reach the last word of your list, it should'nt add "-" to your concenated_string. If its not last word of your string always append "-" string to your concenated_string variable.

1. Clone your fork:

   • git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

   • cd into/cloned/fork-repo
   • git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
   • git fetch upstream

3. Updating your fork from original repo to keep up with their changes:

   • git pull upstream master
   • git push

Validate the INPUT.

$time = strtotime($_POST['dateFrom']);
if ($time) {
  $new_date = date('Y-m-d', $time);
  echo $new_date;
} else {
   echo 'Invalid Date: ' . $_POST['dateFrom'];
  // fix it.
}

You can just change the reference of input value, as below

<div>
    <input type="text" placeholder="Search..." #reference>
    <button (click)="reference.value=''">Clear</button>
</div>

You could always use something like mktime to create a known time (midnight, last night) and use difftime to get a double-precision time difference between the two. For a platform-independant solution, unless you go digging into the details of your libraries, you're not going to do much better than that. According to the C spec, the definition of time_t is implementation-defined (meaning that each implementation of the library can define it however they like, as long as library functions with use it behave according to the spec.)

That being said, the size of time_t on my linux machine is 8 bytes, which suggests a long int or a double. So I did:

int main()
{
    for(;;)
    {
        printf ("%ld\n", time(NULL));
        printf ("%f\n", time(NULL));
        sleep(1);
    }
    return 0;
}

The time given by the %ld increased by one each step and the float printed 0.000 each time. If you're hell-bent on using printf to display time_ts, your best bet is to try your own such experiment and see how it work out on your platform and with your compiler.

do it like this

objArrayy.sort(function(a, b){
 var nameA=a.name.toLowerCase(), nameB=b.name.toLowerCase()
 if (nameA < nameB) //sort string ascending
  return -1
 if (nameA > nameB)
  return 1
 return 0 //default return value (no sorting)
});
console.log(objArray)

I've solved this error by this way.

$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, 'http://www.someurl/' );
curl_setopt ( $ch, CURLOPT_TIMEOUT, 30);
ob_start();
$response = curl_exec ( $ch );
$data = ob_get_clean();
if(curl_getinfo($ch, CURLINFO_HTTP_CODE) == 200 ) success;

Error still occurs, but I can handle response data in variable.

The reason is that by default the /oauth/token endpoint is protected through Basic Access Authentication.

All you need to do is add the Authorization header to your request.

You can easily test it with a tool like curl by issuing the following command:

curl.exe --user [email protected]:12345678 http://localhost:8081/dummy-project-web/oauth/token?grant_type=client_credentials

One-liner run command:

new Process() { StartInfo = new ProcessStartInfo("echo", "Hello, World") }.Start();

Read output of command in shortest amount of reable code:

    var cliProcess = new Process() {
        StartInfo = new ProcessStartInfo("echo", "Hello, World") {
            UseShellExecute = false,
            RedirectStandardOutput = true
        }
    };
    cliProcess.Start();
    string cliOut = cliProcess.StandardOutput.ReadToEnd();
    cliProcess.WaitForExit();
    cliProcess.Close();

Several GUI tools like Squirrel, SQL Workbench/J, AnySQL, ExecuteQuery can export to Excel files.

Most of those tools are listed in the PostgreSQL wiki:

http://wiki.postgresql.org/wiki/Community_Guide_to_PostgreSQL_GUI_Tools

I believe this is much simpler;

dynamic obj = JObject.Parse(jsonString);
string results  = obj.results;
foreach(string result in result.Split('))
{
//Todo
}

var result = input.GroupBy(x=>x.F1,(key,g)=>g.OrderBy(e=>e.F2).First());

With the following code you can ask an instance for its class. You can also compare two instances, wether having the same class.

// CREATE pure SWIFT class
class MySwiftClass {
    var someString : String = "default"
    var someInt    : Int = 5
}

// CREATE instances
let firstInstance = MySwiftClass()
let secondInstance = MySwiftClass()
secondInstance.someString = "Donald"
secondInstance.someInt = 24

// INSPECT instances
if type(of: firstInstance) === MySwiftClass.self {
    print("SUCCESS with ===")
} else {
    print("PROBLEM with ===")
}

if type(of: firstInstance) == MySwiftClass.self {
    print("SUCCESS with ==")
} else {
    print("PROBLEM with ==")
}

// COMPARE CLASS OF TWO INSTANCES
if type(of: firstInstance) === type(of: secondInstance) {
    print("instances have equal class")
} else {
    print("instances have NOT equal class")
}

You need to use the Spring JUnit runner in order to wire in Spring beans from your context. The code below assumes that you have a application context called testContest.xml available on the test classpath.

import org.hibernate.SessionFactory;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import java.sql.SQLException;

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.startsWith;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:**/testContext.xml"})
@Transactional
public class someDaoTest {

    @Autowired
    protected SessionFactory sessionFactory;

    @Test
    public void testDBSourceIsCorrect() throws SQLException {
        String databaseProductName = sessionFactory.getCurrentSession()
                .connection()
                .getMetaData()
                .getDatabaseProductName();
        assertThat("Test container is pointing at the wrong DB.", databaseProductName, startsWith("HSQL"));
    }
}

Note: This works with Spring 2.5.2 and Hibernate 3.6.5

You don't need anything fancy: the following contains a new line (two, actually):

<summary>Tootsie roll tiramisu macaroon wafer carrot cake.       
         Danish topping sugar plum tart bonbon caramels cake.
</summary>

The question is, why isn't this newline having the desired effect: and that's a question about what the recipient of the XML is actually doing with it. For example, if the recipient is translating it to HTML and the HTML is being displayed in the browser, then the newline will be converted to a space by the browser. You need to tell us something about the processing pipeline.

You cannot create a primary key on a view. In SQL Server you can create an index on a view but that is different to creating a primary key.

If you give us more information as to why you want a key on your view, perhaps we can help with that.

SELECT name, GROUP_CONCAT( section ) 
FROM  `tmp` 
GROUP BY name

If you must have a UITextField with 2 lines of text, one option is to add a UILabel as a subview of the UITextField for the second line of text. I have a UITextField in my app that users often do not realize is editable by tapping, and I wanted to add some small subtitle text that says "Tap to Edit" to the UITextField.

CGFloat tapLlblHeight = 10;
UILabel *tapEditLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, textField.frame.size.height - tapLlblHeight - 2, 70, tapLlblHeight)];
tapEditLbl.backgroundColor = [UIColor clearColor];
tapEditLbl.textColor = [UIColor whiteColor];
tapEditLbl.text = @"Tap to Edit";

[textField addSubview:tapEditLbl];

select count(*) from 
(
SELECT distinct column1,column2,column3,column4 FROM abcd
) T

This will give count of distinct group of columns.

You will need to run the following code after your intent is fired to remove the notification.

NotificationManagerCompat.from(this).cancel(null, notificationId);

NB: notificationId is the same id passed to run your notification

array([[1, 2, 3],
[4, 5, 6],
[7, 8, 9]])

find /the_path_you_want_to_find -name index.html

Use filter-branch:

git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch *file_path_relative_to_git_repo*' --prune-empty --tag-name-filter cat -- --all

git push origin *branch_name* -f

Try: Console.WriteLine (type out for a Visual Studio snippet)

Console.WriteLine(stuff);

Another way is to use System.Diagnostics.Debug.WriteLine:

System.Diagnostics.Debug.WriteLine(stuff);

Debug.WriteLine may suit better for Output window in IDE because it will be rendered for both Console and Windows applications. Whereas Console.WriteLine won't be rendered in Output window but only in the Console itself in case of Console Application type.

Another difference is that Debug.WriteLine will not print anything in Release configuration.

You can do it faster without any imports just by using magics:

%env CUDA_DEVICE_ORDER=PCI_BUS_ID
%env CUDA_VISIBLE_DEVICES=0

Notice that all env variable are strings, so no need to use ". You can verify that env-variable is set up by running: %env <name_of_var>. Or check all of them with %env.
