As Nikita Skvortsov pointed out, a self-closing div will not validate. This is because a div is a normal element, not a void element.

According to the HTML5 spec, tags that cannot have any contents (known as void elements) can be self-closing*. This includes the following tags:

area, base, br, col, embed, hr, img, input, 
keygen, link, meta, param, source, track, wbr

The "/" is completely optional on the above tags, however, so <img/> is not different from <img>, but <img></img> is invalid.

*Note: foreign elements can also be self-closing, but I don't think that's in scope for this answer.

you can put div tags inside a td tag, but not directly inside a table or tr tag. examples:

this works:

<table>_x000D_
  <tr>_x000D_
    <td> _x000D_
      <div>This will work.</div> _x000D_
    </td>_x000D_
  </tr>_x000D_
<table>

this does not work:

<table>_x000D_
  <tr>_x000D_
    <div> this does not work. </div> _x000D_
  </tr>_x000D_
</table>

nor does this work:

<table>_x000D_
  <div> this does not work. </div>_x000D_
</table>

If you would like to compress the conversion of a string to a SecureString into a LINQ statement you can express it as follows:

var plain  = "The quick brown fox jumps over the lazy dog";
var secure = plain
             .ToCharArray()
             .Aggregate( new SecureString()
                       , (s, c) => { s.AppendChar(c); return s; }
                       , (s)    => { s.MakeReadOnly(); return s; }
                       );

However, keep in mind that using LINQ does not improve the security of this solution. It suffers from the same flaw as any conversion from string to SecureString. As long as the original string remains in memory the data is vulnerable.

That being said, what the above statement can offer is keeping together the creation of the SecureString, its initialization with data and finally locking it from modification.

With less you can set it up like this;

.table tbody tr {
    &.error > td { background-color: red !important; }
    &.error:hover > td { background-color: yellow !important; }
    &.success > td { background-color: green !important; }
    &.success:hover > td { background-color: yellow !important; }
    ...
}

That did the trick for me.

Escaping parameters like that is usually source of frustration and feels a lot like a time wasted. I see you're on v2 so I would suggest using a technique that Joel "Jaykul" Bennet blogged about a while ago.

Long story short: you just wrap your string with @' ... '@ :

Start-Process \\server\toto.exe @'
-batch=B -param="sort1;parmtxt='Security ID=1234'"
'@

(Mind that I assumed which quotes are needed, and which things you were attempting to escape.) If you want to work with the output, you may want to add the -NoNewWindow switch.

BTW: this was so important issue that since v3 you can use --% to stop the PowerShell parser from doing anything with your parameters:

\\server\toto.exe --% -batch=b -param="sort1;paramtxt='Security ID=1234'"

... should work fine there (with the same assumption).

Unless you need to access more memory that 32b addressing will allow you, the benefits will be small, if any.

When running on 64b CPU, you get the same memory interface no matter if you are running 32b or 64b code (you are using the same cache and same BUS).

While x64 architecture has a few more registers which allows easier optimizations, this is often counteracted by the fact pointers are now larger and using any structures with pointers results in a higher memory traffic. I would estimate the increase in the overall memory usage for a 64b application compared to a 32b one to be around 15-30 %.

You can use the contains method

var result = parent.contains(child);

or you can try to use compareDocumentPosition()

var result = nodeA.compareDocumentPosition(nodeB);

The last one is more powerful: it return a bitmask as result.

Use this command:

ls -ltr /mig/mthome/09/log/*

instead of:

ls -ltr /mig/mthome/09/log

to get the full path in the listing.

Cast the null literal: (DateTime?)null or (Nullable<DateTime>)null.

You can also use default(DateTime?) or default(Nullable<DateTime>)

And, as other answers have noted, you can also apply the cast to the DateTime value rather than to the null literal.

EDIT (adapted from my comment to Prutswonder's answer):

The point is that the conditional operator does not consider the type of its assignment target, so it will only compile if there is an implicit conversion from the type of its second operand to the type of its third operand, or from the type of its third operand to the type of its second operand.

For example, this won't compile:

bool b = GetSomeBooleanValue();
object o = b ? "Forty-two" : 42;

Casting either the second or third operand to object, however, fixes the problem, because there is an implicit conversion from int to object and also from string to object:

object o = b ? "Forty-two" : (object)42;

or

object o = b ? (object)"Forty-two" : 42;

If you expect the data to be numeric in some form, and all you are interested in doing is converting the result to a numeric value, I would suggest:

for (Object o:list) {
  Double.parseDouble(o.toString);
}

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

I agree with Quentin. It doesn't make sense as to why you want to do it like that. It's part of the Semantic Web concept. You have to plan out the objects of your web site for future integration/expansion. Another web app or web site cannot interact with your content if it doesn't follow the proper use-case.

IE and Firefox are two different beasts. There are a lot of things that IE allows that Firefox and other standards-aware browsers reject.

If you're trying to create buttons without actually submitting data then use a combination of DIV/CSS.

Based on Chris Johnsen's answer,

Add a global "squash" alias from bash: (or Git Bash on Windows)

git config --global alias.squash '!f(){ git reset --soft HEAD~${1} && git commit --edit -m"$(git log --format=%B --reverse HEAD..HEAD@{1})"; };f'

... or using Windows' Command Prompt:

git config --global alias.squash "!f(){ git reset --soft HEAD~${1} && git commit --edit -m\"$(git log --format=%B --reverse HEAD..HEAD@{1})\"; };f"

Your ~/.gitconfig should now contain this alias:

[alias]
    squash = "!f(){ git reset --soft HEAD~${1} && git commit --edit -m\"$(git log --format=%B --reverse HEAD..HEAD@{1})\"; };f"

Usage:

git squash N

... Which automatically squashes together the last N commits, inclusive.

Note: The resultant commit message is a combination of all the squashed commits, in order. If you are unhappy with that, you can always git commit --amend to modify it manually. (Or, edit the alias to match your tastes.)

OP asked for users connected to a particular database:

-- Who's currently connected to my_great_database?
SELECT * FROM pg_stat_activity 
  WHERE datname = 'my_great_database';

This gets you all sorts of juicy info (as others have mentioned) such as

• userid (column usesysid)
• username (usename)
• client application name (appname), if it bothers to set that variable -- psql does :-)
• IP address (client_addr)
• what state it's in (a couple columns related to state and wait status)
• and everybody's favorite, the current SQL command being run (query)

Commonly base64 it is used for images. if you like to decode an image (jpg in this example with org.apache.commons.codec.binary.Base64 package):

byte[] decoded = Base64.decodeBase64(imageJpgInBase64);
FileOutputStream fos = null;
fos = new FileOutputStream("C:\\output\\image.jpg");
fos.write(decoded);
fos.close();

If somehow you want a simple, yet different solution, you can use the {**dict} syntax:

from collections import OrderedDict

ordered = OrderedDict([('method', 'constant'), ('data', '1.225')])
regular = {**ordered}

Another possible cause of this is trying to use the ;x509; module on something that is not X.509.

The server certificate is X.509 format, but the private key is RSA.

So:

openssl rsa -noout -text -in privkey.pem
openssl x509 -noout -text -in servercert.pem

Run a custom maven command in Eclipse as follows:

1. Right-click the maven project or pom.xml
2. Expand Run As
3. Select Maven Build...
4. Set Goals to the command, such as: clean install -X

Note: Eclipse prefixes the command with mvn automatically.

Java dynamically loads classes, so your universe of classes would be only those that have already been loaded (and not yet unloaded). Perhaps you can do something with a custom class loader that could check the supertypes of each loaded class. I don't think there's an API to query the set of loaded classes.

The issue is that the * is getting interpreted by your shell and is expanding to a file named TEST_FILE that happens to be in your current working directory, so you're telling find to execute the command named TEST_FILE which doesn't exist. I'm not sure what you're trying to accomplish with that *, you should just remove it.

Furthermore, you should use the idiom -exec program '{}' \+ instead of -exec program '{}' \; so that find doesn't fork a new process for each file. With ;, a new process is forked for each file, whereas with +, it only forks one process and passes all of the files on a single command line, which for simple programs like chmod is much more efficient.

Lastly, chmod can do recursive changes on its own with the -R flag, so unless you need to search for specific files, just do this:

chmod -R 777 /Users/Test/Desktop/PATH

string str = "asasdkopaksdpoadks";
byte[] data = Encoding.ASCII.GetBytes(str);
MemoryStream stm = new MemoryStream(data, 0, data.Length);

ParseExact is told the format of the date it is expected to parse, not the format you wish to get out.

$invoice = '01-Jul-16'
[datetime]::parseexact($invoice, 'dd-MMM-yy', $null)

If you then wish to output a date string:

[datetime]::parseexact($invoice, 'dd-MMM-yy', $null).ToString('yyyy-MM-dd')

make sure you use the POST to insert the data. Actually you were using GET.

Thanks for all the answers. I tried all of them but none of them worked for me. What did work was to delete the applicationhost.config from the .vs folder (found in the folder of your project/solution) and create a new virtual directory (Project Properties > Web > Create Virtual Directory). Hope this will help somebody else.

Please check the below answer. It works for me

To kill a process by a specific keyword you could create an alias in ~/.bashrc (linux) or ~/.bash_profile (mac).

alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"

My solution:

Hash[ post.attributes.map{ |a| [a, post[a]] } ]

Usually it happen in TochableHighlight. Anyway error mean that you must used single element inside the whatever component.

Solution : You can use single view inside parent and anything can be used inside that View. See the attached picture

enter image description here

in my case problem was build tools version which was 23.0.0 rc3 and i changed to 22.0.1 and my problem fixed.

You will need to use different IP addresses. The server, whether Apache or IIS, grabs the traffic based on the IP and Port, which ever they are bound to listen to. Once it starts listening, then it uses the headers, such as the server name to filter and determine what site is being accessed. You can't do it will simply changing the server name in the request

Yes, This is possible. Right click on the table and Click on Edit Top 200 Rows as show in image below

Then click anywhere inside the result grid, to enable SQL Icon "Show Sql Pane". This will open sql editor for the table you opted to edit, here you can write your own sql query and then you can directly edit the result set of the query.

Try this:

#include <windows.h>

int main ()

{
    system ("start notepad.exe") // As an example. Change [notepad] to any executable file //

    return 0 ;
}

If you need run thread predioticly with different codes here is example:

Listener:

public interface ESLThreadListener {

    public List onBackground();

    public void onPostExecute(List list);

}

Thread Class

public class ESLThread extends AsyncTask<Void, Void, List> {


    private ESLThreadListener mListener;

    public ESLThread() {

        if(mListener != null){

            mListener.onBackground();
        }
    }

    @Override
    protected List doInBackground(Void... params) {

        if(mListener != null){

            List list = mListener.onBackground();

            return list;
        }

        return null;
    }

    @Override
    protected void onPostExecute(List t) {
        if(mListener != null){

            if ( t != null) {
                mListener.onPostExecute(t);
            }
        }

    }


    public void setListener(ESLThreadListener mListener){

        this.mListener = mListener;
    }
}

Run different codes:

  ESLThread thread = new ESLThread();
                        thread.setListener(new ESLThreadListener() {
                            @Override
                            public List onBackground() {
                                List<EntityShoppingListItems>  data = RoomDB.getDatabase(context).sliDAO().getSL(fId);

                                return data;

                            }

                            @Override
                            public void onPostExecute(List t) {

                                List<EntityShoppingListItems> data = (List<EntityShoppingListItems>)t;
                                adapter.setList(data);
                            }
                        });

                        thread.execute();

This works for me:

1. Before installing nvm, run this in terminal: touch ~/.bash_profile

2. After, run this in terminal:
   curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

3. Important... - DO NOT forget to Restart your terminal OR use command source ~/.nvm/nvm.sh (this will refresh the available commands in your system path).

4. In the terminal, use command nvm --version and you should see the version

Very simplified without much formality: every edge is considered exactly twice, and every node is processed exactly once, so the complexity has to be a constant multiple of the number of edges as well as the number of vertices.

If it's a PHP issue, you could simply alter the configuration file php.ini wherever it's located and update the settings for PORT/SOCKET-PATH etc to make it connect to the server.

In my case, I opened the file php.ini and did

mysql.default_socket = /var/run/mysqld/mysqld.sock
mysqli.default_socket = /var/run/mysqld/mysqld.sock

And it worked straight away. I have to admit, I took hint from the accepted answer by @Joni

A priority queue is an abstract data type that captures the idea of a container whose elements have "priorities" attached to them. An element of highest priority always appears at the front of the queue. If that element is removed, the next highest priority element advances to the front.

The C++ standard library defines a class template priority_queue, with the following operations:

push: Insert an element into the prioity queue.

top: Return (without removing it) a highest priority element from the priority queue.

pop: Remove a highest priority element from the priority queue.

size: Return the number of elements in the priority queue.

empty: Return true or false according to whether the priority queue is empty or not.

The following code snippet shows how to construct two priority queues, one that can contain integers and another one that can contain character strings:

#include <queue>

priority_queue<int> q1;
priority_queue<string> q2;

The following is an example of priority queue usage:

#include <string>
#include <queue>
#include <iostream>

using namespace std;  // This is to make available the names of things defined in the standard library.

int main()
{
    piority_queue<string> pq; // Creates a priority queue pq to store strings, and initializes the queue to be empty.

    pq.push("the quick");
    pq.push("fox");
    pq.push("jumped over");
    pq.push("the lazy dog");

    // The strings are ordered inside the priority queue in lexicographic (dictionary) order:
    // "fox", "jumped over", "the lazy dog", "the quick"
    //  The lowest priority string is "fox", and the highest priority string is "the quick"

    while (!pq.empty()) {
       cout << pq.top() << endl;  // Print highest priority string
       pq.pop();                    // Remmove highest priority string
    }

    return 0;
}

The output of this program is:

the quick
the lazy dog
jumped over
fox

Since a queue follows a priority discipline, the strings are printed from highest to lowest priority.

Sometimes one needs to create a priority queue to contain user defined objects. In this case, the priority queue needs to know the comparison criterion used to determine which objects have the highest priority. This is done by means of a function object belonging to a class that overloads the operator (). The overloaded () acts as < for the purpose of determining priorities. For example, suppose we want to create a priority queue to store Time objects. A Time object has three fields: hours, minutes, seconds:

struct Time {
    int h; 
    int m; 
    int s;
};

class CompareTime {
    public:
    bool operator()(Time& t1, Time& t2) // Returns true if t1 is earlier than t2
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
}

A priority queue to store times according the the above comparison criterion would be defined as follows:

priority_queue<Time, vector<Time>, CompareTime> pq;

Here is a complete program:

#include <iostream>
#include <queue>
#include <iomanip>

using namespace std;

struct Time {
    int h; // >= 0
    int m; // 0-59
    int s; // 0-59
};

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2)
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
};

int main()
{
    priority_queue<Time, vector<Time>, CompareTime> pq;

    // Array of 4 time objects:

    Time t[4] = { {3, 2, 40}, {3, 2, 26}, {5, 16, 13}, {5, 14, 20}};

    for (int i = 0; i < 4; ++i)
       pq.push(t[i]);

    while (! pq.empty()) {
       Time t2 = pq.top();
       cout << setw(3) << t2.h << " " << setw(3) << t2.m << " " <<
       setw(3) << t2.s << endl;
       pq.pop();
    }

    return 0;
}

The program prints the times from latest to earliest:

5  16  13
5  14  20
3   2  40
3   2  26

If we wanted earliest times to have the highest priority, we would redefine CompareTime like this:

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2) // t2 has highest prio than t1 if t2 is earlier than t1
    {
       if (t2.h < t1.h) return true;
       if (t2.h == t1.h && t2.m < t1.m) return true;
       if (t2.h == t1.h && t2.m == t1.m && t2.s < t1.s) return true;
       return false;
    }

You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.

For example, if you are running Win 7 64-bit, or Win Server 2008 R2, you may install 32-bit JRE in "C:\Program Files (x86)\Java\jre6" and 64-bit JRE in "C:\Program Files\Java\jre6", and perhaps IBM Java 6 in "C:\Program Files (x86)\IBM\Java60\jre".

The Java Control Panel app theoretically has the ability to manage multiple runtimes: Java tab >> View... button

There are tabs for User and System settings. You can add additional runtimes with Add or Find, but once you have finished adding runtimes and hit OK, you have to hit Apply in the main Java tab frame, which is not as obvious as it could be - otherwise your changes will be lost.

If you have multiple versions installed, only the main version will auto-update. I have not found a solution to this apart from the weak workaround of manually updating whenever I see an auto-update, so I'd love to know if anyone has a fix for that.

Most Java IDEs allow you to select any Java runtime on your machine to build against, but if not using an IDE, you can easily manage this using environment variables in a cmd window. Your PATH and the JAVA_HOME variable determine which runtime is used by tools run from the shell. Set the JAVA_HOME to the jre directory you want and put the bin directory into your path (and remove references to other runtimes) - with IBM you may need to add multiple bin directories. This is pretty much all the set up that the default system Java does. You can also set CLASSPATH, ANT_HOME, MAVEN_HOME, etc. to unique values to match your runtime.

Stopping (Killing) a thread mid-way is not recommended. The API is actually deprecated.

However,you can get more details including workarounds here: How do you kill a thread in Java?

This is typically solved using regex. There are many variations of solutions however. Depending on how strict you need to be, and if you have custom requirements for validation, or will accept any valid email address.

See this page for reference: http://www.regular-expressions.info/email.html

your max factor is not more than your number, so, let's say

def factors(n):
    factors = []
    for i in range(1, n//2+1):
        if n % i == 0:
            factors.append (i)
    factors.append(n)

    return factors

voilá!

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

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

Or this style (Simple)

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

Not This (Simple but with boolean search predicates)

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

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

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

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

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

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

This solution is for the people who don't use jQuery and to improve performance by not moving the script to bottom of the page, and the problem is that the script is loaded before the html elements are loaded. Add your code in this function body

window.onload=()=>{
    
    // your code here

    // example
    let element=document.getElementById("elementId");
    console.log(element);

};

add everything that has to work only after the document is loaded and keep other functions that has to be executed as soon as the script is loaded outside the function.

I recommend this method instead of moving down the script, because if the script is on top, the browser will try to download it as soon as it sees the script tag, if it is on the bottom of the page, it will take some more time to load it and until that time no event listeners in the script will work. in this case all other functions could be called and the window.onload will get called once everything is loaded.

They are called the Positional Parameters.

3.4.1 Positional Parameters

A positional parameter is a parameter denoted by one or more digits, other than the single digit 0. Positional parameters are assigned from the shell’s arguments when it is invoked, and may be reassigned using the set builtin command. Positional parameter N may be referenced as ${N}, or as $N when N consists of a single digit. Positional parameters may not be assigned to with assignment statements. The set and shift builtins are used to set and unset them (see Shell Builtin Commands). The positional parameters are temporarily replaced when a shell function is executed (see Shell Functions).

When a positional parameter consisting of more than a single digit is expanded, it must be enclosed in braces.

fmt.Sprintf("%v",value);

If you know the specific type of value use the corresponding formatter for example %d for int

Use Pattern and Matcher

public class Chk {

    public static void main(String[] args) {

        String s = "test string (67)";
        ArrayList<String> arL = new ArrayList<String>();
        ArrayList<String> inL = new ArrayList<String>();

        Pattern pat = Pattern.compile("\\(\\w+\\)");
        Matcher mat = pat.matcher(s);

        while (mat.find()) {

            arL.add(mat.group());
            System.out.println(mat.group());

        }

        for (String sx : arL) {

            Pattern p = Pattern.compile("(\\w+)");
            Matcher m = p.matcher(sx);

            while (m.find()) {

                inL.add(m.group());
                System.out.println(m.group());
            }
        }

        System.out.println(inL);

    }

}

Where is the problem: It is forbidden to delete items from collection inside a foreach loop.

Solution: Either do it like Widor wrote, or use two loops. In the first pass over DataTable you only store (in a temporary list) the references to rows you want to delete. Then in the second pass over your temporary list you delete those rows.

I had the same problem today. Try it!

sudo chown -R  [yourgroup]  /home/[youruser]/.composer/cache/repo/https---packagist.org/


sudo chown -R  [yourgroup]   /home/[youruser]/.composer/cache/files/

I see you have all the settings right. You just need to end the local web server and start it again with

php artisan serve

Everytime you change your .env file, you need tor restart the server for the new options to take effect.

Or clear and cache your configuration with

php artisan config:cache

For those discovering this now and the above answers didn't work, the issue I had was the screen wasn't big enough. I added this when initializing my ChromeDriver, and it fixed the problem:

options.add_argument("window-size=1200x600")

There is another way of controlling error handling that works well for loops. Create a string variable called here and use the variable to determine how a single error handler handles the error.

The code template is:

On error goto errhandler

Dim here as String

here = "in loop"
For i = 1 to 20 
    some code
Next i

afterloop:
here = "after loop"
more code

exitproc:    
exit sub

errhandler:
If here = "in loop" Then 
    resume afterloop
elseif here = "after loop" Then
    msgbox "An error has occurred" & err.desc
    resume exitproc
End if

You need to use an Angular form directive on the select. You can do that with ngModel. For example

@Component({
  selector: 'my-app',
  template: `
    <h2>Select demo</h2>
    <select [(ngModel)]="selectedCity" (ngModelChange)="onChange($event)" >
      <option *ngFor="let c of cities" [ngValue]="c"> {{c.name}} </option>
    </select>
  `
})
class App {
  cities = [{'name': 'SF'}, {'name': 'NYC'}, {'name': 'Buffalo'}];
  selectedCity = this.cities[1];

  onChange(city) {
    alert(city.name);
  }
}

The (ngModelChange) event listener emits events when the selected value changes. This is where you can hookup your callback.

Note you will need to make sure you have imported the FormsModule into the application.

Here is a Plunker

I'd like to point that something that i missed ...

I'm new at Laravel, and i didn't copy the "use Illuminate....." because i really didn'at paid atention, because right above the function boot you alread have a use Statement.

Hope that helps anyone

**use Illuminate\Support\Facades\Schema;**

public function boot()
{
    Schema::defaultStringLength(191);

Your json string is wrapped within square brackets ([]), hence it is interpreted as array instead of single RetrieveMultipleResponse object. Therefore, you need to deserialize it to type collection of RetrieveMultipleResponse, for example :

var objResponse1 = 
    JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);

I think this is the simplest alias, add to your ~/.gitconfig

[alias]
  publish-branch = !git push -u origin $(git rev-parse --abbrev-ref HEAD)

You just run

git publish-branch

and... it publishes the branch

Could not figure out what you want, but you need something like this ? :

?def a = { b -> b = 1 }
?bValue = a()
println b // prints 1

Now bValue contains the value of b which is a variable in the closure a. Now you can do anything with bValue Let me know if i have misunderstood your question

Difference between == (equal) and === (identical equal)

PHP provides two comparison operators to check equality of two values. The main difference between of these two is that '==' checks if the values of the two operands are equal or not. On the other hand, '===' checks the values as well as the type of operands are equal or not.

== (Equal)

=== (Identical equal)

Example =>

<?php 
    $val1 = 1234;
    $val2 = "1234";
    var_dump($val1 == $val2);// output => bool(true)
    //It checks only operands value
?> 


<?php 
    $val1 = 1234;
    $val2 = "1234";
    var_dump($val1 === $val2);// output => bool(false)
    //First it checks type then operands value
?> 

if we type cast $val2 to (int)$val2 or (string)$val1 then it returns true

   <?php 
        $val1 = 1234;
        $val2 = "1234";
        var_dump($val1 === (int)$val2);// output => bool(true)
        //First it checks type then operands value
    ?> 

OR

  <?php 
        $val1 = 1234;
        $val2 = "1234";
        var_dump($val1 === (int)$val2);// output => bool(true)
        //First it checks type then operands value
    ?> 

In Pandas version 0.13 and greater the index level names are immutable (type FrozenList) and can no longer be set directly. You must first use Index.rename() to apply the new index level names to the Index and then use DataFrame.reindex() to apply the new index to the DataFrame. Examples:

For Pandas version < 0.13

df.index.names = ['Date']

For Pandas version >= 0.13

df = df.reindex(df.index.rename(['Date']))

Warnings you can recover from. Errors you can't. That's my heuristic, others may have other ideas.

For example, let's say you enter/import the name "Angela Müller" into your application (note the umlaut over the u). Your code/database may be English only (though it probably shouldn't be in this day and age) and could therefore warn that all "unusual" characters had been converted to regular English characters.

Contrast that with trying to write that information to the database and getting back a network down message for 60 seconds straight. That's more of an error than a warning.

You can use curl or wget to retrieve the raw data, or you can use w3m -dump to have a nice text representation of a web page.

$ foo=$(w3m -dump http://www.example.com/); echo $foo
You have reached this web page by typing "example.com", "example.net","example.org" or "example.edu" into your web browser. These domain names are reserved for use in documentation and are not available for registration. See RFC 2606, Section 3.

2 things.

• The query has to complete on sql server before the return value is sent.

• The results have to be captured and then finish executing before the return value gets to the object.

In English, finish the work and then retrieve the value.

this will not work:

                cmm.ExecuteReader();
                int i = (int) cmm.Parameters["@RETURN_VALUE"].Value;

This will work:

                        SqlDataReader reader = cmm.ExecuteReader();
                        reader.Close();

                        foreach (SqlParameter prm in cmd.Parameters)
                        {
                           Debug.WriteLine("");
                           Debug.WriteLine("Name " + prm.ParameterName);
                           Debug.WriteLine("Type " + prm.SqlDbType.ToString());
                           Debug.WriteLine("Size " + prm.Size.ToString());
                           Debug.WriteLine("Direction " + prm.Direction.ToString());
                           Debug.WriteLine("Value " + prm.Value);

                        }

if you are not sure check the value of the parameter before during and after the results have been processed by the reader.

Convert Map to an array using Array.from, sort array, convert back to Map, e.g.

new Map(
  Array
    .from(eventsByDate)
    .sort((a, b) => {
      // a[0], b[0] is the key of the map
      return a[0] - b[0];
    })
)

In any realistic system, no, creating a stack frame will always be more expensive than an INC and a JMP. That's why really good compilers automatically transform tail recursion into a call to the same frame, i.e. without the overhead, so you get the more readable source version and the more efficient compiled version. A really, really good compiler should even be able to transform normal recursion into tail recursion where that is possible.

This works for me:

 "jest": {
    "collectCoverage": true,
    "coverageReporters": ["json", "html"]
  },
  "scripts": {
    "test": "jest  --coverage"
  },

Run:

yarn/npm test

You could use an asymmetrical border to make curves with CSS.

border-radius: 50%/100px 100px 0 0;

The problem I see here is that "sum" is an aggregate function.

first, you need to fix the query itself.

Select sum(c_counts + f_counts) total, [column to group sums by]
from table
group by [column to group sums by]

then, you can sort it:

Select *
from (query above) a
order by total

EDIT: But see post by Virat. Perhaps what you want is not the sum of your total fields over a group, but just the sum of those fields for each record. In that case, Virat has the right solution.

I had to set the event to null using the prop and the attr. I couldn't do it with one or the other. I also could not get .unbind to work. I am working on a TD element.

For VB.NET developers Use this generic sub to mark the child state, easy to use

Notes:

• PromatCon: the entity object
• amList: is the child list that you want to add or modify
• rList: is the child list that you want to remove

updatechild(objCas.ECC_Decision, PromatCon.ECC_Decision.Where(Function(c) c.rid = objCas.rid And Not objCas.ECC_Decision.Select(Function(x) x.dcid).Contains(c.dcid)).toList)

Sub updatechild(Of Ety)(amList As ICollection(Of Ety), rList As ICollection(Of Ety))
        If amList IsNot Nothing Then
            For Each obj In amList
                Dim x = PromatCon.Entry(obj).GetDatabaseValues()
                If x Is Nothing Then
                    PromatCon.Entry(obj).State = EntityState.Added
                Else
                    PromatCon.Entry(obj).State = EntityState.Modified
                End If
            Next
        End If

        If rList IsNot Nothing Then
            For Each obj In rList.ToList
                PromatCon.Entry(obj).State = EntityState.Deleted
            Next
        End If
End Sub

PromatCon.SaveChanges()

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

My application has a couple views that required a customized navigation bar in the UI for look & feel, however without navigation controller. And the application is required to support iOS version prior to iOS 11, so the handy safe area layout guide could not be used, and I have to adjust the position and height of navigation bar programmatically.

I attached the Navigation Bar to its superview directly, skipping the safe area layout guide as mentioned above. And the status bar height could be retrieved from UIApplication easily, but the default navigation bar height is really a pain-ass...

It struck me for almost half a night, with a number of searching and testing, until I finally got the hint from another post (not working to me though), that you could actually get the height from UIView.sizeThatFits(), like this:

- (void)viewWillLayoutSubviews {
    self.topBarHeightConstraint.constant = [UIApplication sharedApplication].statusBarFrame.size.height;
    self.navBarHeightConstraint.constant = [self.navigationBar sizeThatFits:CGSizeZero].height;

    [super viewWillLayoutSubviews];    
}

Finally, a perfect navigation bar looking exactly the same as the built-in one!

@FindBy(xpath = "//button[@class='btn btn-primary' and contains(text(), 'Submit')]") private WebElementFacade submitButton;

When writing my own unique_ptr, I found this case. Given std::unique_ptr's operator==:

template<class T1, class D1, class T2, class D2>
bool operator==(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);

template <class T, class D>
bool operator==(const unique_ptr<T, D>& x, nullptr_t) noexcept;

template <class T, class D>
bool operator==(nullptr_t, const unique_ptr<T, D>& x) noexcept;

And this test case from libstdcxx:

  std::unique_ptr<int> ptr;
  if (ptr == 0)
    { }
  if (0 == ptr)
    { }
  if (ptr != 0)
    { }
  if (0 != ptr)
    { }

Note because that ptr has a explicit operator bool() const noexcept;, so operator overload resolution works fine here, e.g., ptr == 0 chooses

 template <class T, class D>
 bool operator==(const unique_ptr<T, D>& x, nullptr_t) noexcept;`.

If it has no explicit keyword here, ptr in ptr == 0 will be converted into bool, then bool will be converted into int, because bool operator==(int, int) is built-in and 0 is int. What is waiting for us is ambiguous overload resolution error.

year, the thread must be join(). when the main exit

I like to start with a class like this class settings { public int X {get;set;} public string Y { get; set; } // repeat as necessary

 public settings()
 {
    this.X = defaultForX;
    this.Y = defaultForY;
    // repeat ...
 }
 public void Parse(Uri uri)
 {
    // parse values from query string.
    // if you need to distinguish from default vs. specified, add an appropriate property

 }

This has worked well on 100's of projects. You can use one of the many other parsing solutions to parse values.

== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators.

((a[0] & 1) == 0)

Similarly for all parts of the if condition.

I found this solution in "Super useful bits of PHP, Form and JavaScript code" at Skytopia.

Inside "page1.php" or "page1.html":

// Send the variables myNumber=1 and myFruit="orange" to the new PHP page...
<a href="page2c.php?myNumber=1&myFruit=orange">Send variables via URL!</a> 

    //or as I needed it.
    <a href='page2c.php?myNumber={$row[0]}&myFruit={$row[1]}'>Send variables</a>

Inside "page2c.php":

<?php
    // Retrieve the URL variables (using PHP).
    $num = $_GET['myNumber'];
    $fruit = $_GET['myFruit'];
    echo "Number: ".$num."  Fruit: ".$fruit;
?>

I have found two errors during the installing of Magento to localhost.
There are PHP Extension xsl and intl and I have solved the issue by following steps.

1. Open php.ini
2. Remove '#' cha from the lines extension=php_xsl.dll and extension=php_intl.dll.
3. Save the file and restart xamp again
4. Click Try Again on Magento installation page.

Then all the things were passed as well as following picture.

Following example uses InputBox method to validate user entry to unhide sheets: Important thing here is to use wrap InputBox variable inside StrPtr so it could be compared to '0' when user chose to click 'x' icon on the InputBox.

Sub unhidesheet()

Dim ws As Worksheet
Dim pw As String

pw = InputBox("Enter Password to Unhide Sheets:", "Unhide Data Sheets")
If StrPtr(pw) = 0 Then

   Exit Sub
ElseIf pw = NullString Then
   Exit Sub
ElseIf pw = 123456 Then
    For Each ws In ThisWorkbook.Worksheets
        ws.Visible = xlSheetVisible
    Next
End If
End Sub

You can simply make the start_date required using

You don't even need the checkform() then.

Using capital letters as format characters yields uppercase hexadecimal

In [8]: '{:X}'.format(127)

General

Single elements of a tuple a can be accessed -in an indexed array-like fashion-

via a[0], a[1], ... depending on the number of elements in the tuple.

Example

If your tuple is a=(3,"a")

• a[0] yields 3,
• a[1] yields "a"

Concrete answer to question

def tup():
  return (3, "hello")

tup() returns a 2-tuple.

In order to "solve"

i = 5 + tup()  # I want to add just the three

you select the 3 by

tup()[0|    #first element

so in total

i = 5 + tup()[0]

Alternatives

Go with namedtuple that allows you to access tuple elements by name (and by index). Details at https://docs.python.org/3/library/collections.html#collections.namedtuple

>>> import collections
>>> MyTuple=collections.namedtuple("MyTuple", "mynumber, mystring")
>>> m = MyTuple(3, "hello")
>>> m[0]
3
>>> m.mynumber
3
>>> m[1]
'hello'
>>> m.mystring
'hello'

This is a very old question, but as VIM is still relevant something should be clarified.

Every answer and comment here as of October 2018 has referred to what would commonly be known as a "cut" action, thus using any of them will replace whatever is currently in VIM's unnamed register. This register tends to be treated like a default copy/paste clipboard, so none of these answers will work as desired if you are deleting the rest of a line to paste something in the same place afterward, as whatever was just deleted will be subsequently pasted in place of whatever was yanked before.

The true delete command in the OP's context is "_D (or "_C if insert mode is desired) This sends the deleted content into the black hole register, designated by "_, where it will bother no one ever again (although you can still undo this action using u).

That being said, whatever was last yanked is stored in the 0 register, and even if it gets replaced in the unnamed register, it can still be pasted using "0p.

Learn more about the black hole register and registers in general for extra VIM fun!

It seems none of the answers format it in the actual title case: "How to Land Your Dream Job", "To Kill a Mockingbird", etc. so I've made my own method. Works best for English languages texts.

You need to make sure images come first and put in a comma after the background image call. then it actually does work:

    background:url(egg.png) no-repeat 70px 2px #82d4fe; /* Old browsers */
background:url(egg.png) no-repeat 70px 2px, -moz-linear-gradient(top, #82d4fe 0%, #1db2ff 78%) ; /* FF3.6+ */
background:url(egg.png) no-repeat 70px 2px, -webkit-gradient(linear, left top, left bottom, color-stop(0%,#82d4fe), color-stop(78%,#1db2ff)); /* Chrome,Safari4+ */

If you want to $broadcast use the $rootScope:

$scope.startScanner = function() {

    $rootScope.$broadcast('scanner-started');
}

And then to receive, use the $scope of your controller:

$scope.$on('scanner-started', function(event, args) {

    // do what you want to do
});

If you want you can pass arguments when you $broadcast:

$rootScope.$broadcast('scanner-started', { any: {} });

And then receive them:

$scope.$on('scanner-started', function(event, args) {

    var anyThing = args.any;
    // do what you want to do
});

Documentation for this inside the Scope docs.

THis method allows you to have more flexibility of styling your entire content. Effectivly creating two containers that you can style. THe HTML Body tag which serves as your background, and the div with an id of container which contains your content.

This then allows you to position your content within the page, while styling a background or other effects without issue. THink of it as a "Frame" for the content.

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}

The centos dockerfile has a default command bash.

That means, when run in background (-d), the shell exits immediately.

Update 2017

More recent versions of docker authorize to run a container both in detached mode and in foreground mode (-t, -i or -it)

In that case, you don't need any additional command and this is enough:

docker run -t -d centos

The bash will wait in the background.
That was initially reported in kalyani-chaudhari's answer and detailed in jersey bean's answer.

vonc@voncvb:~$ d ps -a

Note that for alpine, Marinos An reports in the comments:

docker run -t -d alpine/git does not keep the process up.
Had to do: docker run --entrypoint "/bin/sh" -it alpine/git

Original answer (2015)

As mentioned in this article:

Instead of running with docker run -i -t image your-command, using -d is recommended because you can run your container with just one command and you don’t need to detach terminal of container by hitting Ctrl + P + Q.

However, there is a problem with -d option. Your container immediately stops unless the commands keep running in foreground.
Docker requires your command to keep running in the foreground. Otherwise, it thinks that your applications stops and shutdown the container.

The problem is that some application does not run in the foreground. How can we make it easier?

In this situation, you can add tail -f /dev/null to your command.
By doing this, even if your main command runs in the background, your container doesn’t stop because tail is keep running in the foreground.

So this would work:

docker run -d centos tail -f /dev/null

A docker ps would show the centos container still running.

From there, you can attach to it or detach from it (or docker exec some commands).

Do you have Zend, IonCube, or xDebug installed? If so, that is probably where you are getting this error from.

I ran into this a few years ago, and it ended up being Zend putting that limit there, not PHP. Of course removing it will let you go past the 100 iterations, but you will eventually hit the memory limits.

Dragging like jQueryUI: JsFiddle

You can drag the element from any point without weird centering.

$(document).ready(function() {

        var $body = $('body');
        var $target = null;
        var isDraggEnabled = false;

        $body.on("mousedown", "div", function(e) {

            $this = $(this);
            isDraggEnabled = $this.data("draggable");

            if (isDraggEnabled) {
                if(e.offsetX==undefined){
                    x = e.pageX-$(this).offset().left;
                    y = e.pageY-$(this).offset().top;
                }else{
                    x = e.offsetX;
                    y = e.offsetY;
                };

                $this.addClass('draggable');
                $body.addClass('noselect');
                $target = $(e.target);
            };

        });

         $body.on("mouseup", function(e) {
            $target = null;
            $body.find(".draggable").removeClass('draggable');
            $body.removeClass('noselect');
        });

         $body.on("mousemove", function(e) {
            if ($target) {
                $target.offset({
                    top: e.pageY  - y,
                    left: e.pageX - x
                });
            };     
         });

    });

You can use assertThrows(), But with assertThrows your assertion will pass even if the thrown exception is of child type.

This is because, JUnit 5 checks exception type by calling Class.isIntance(..), Class.isInstance(..) will return true even if the exception thrown is of the child types.

The workaround for this is to assert on Class:

Throwable throwable =  assertThrows(Throwable.class, () -> {
    service.readFile("sampleFile.txt");
});
assertEquals(FileNotFoundException.class, throwable.getClass());

The issue isn't actually a syntax error, the Hive ParseException is just caused by a reserved keyword in Hive (in this case, end).

The solution: use backticks around the offending column name:

CREATE EXTERNAL TABLE moveProjects (cid string, `end` string, category string)
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES ("dynamodb.table.name" = "Projects",
    "dynamodb.column.mapping" = "cid:cid,end:end,category:category");

With the added backticks around end, the query works as expected.

Reserved words in Amazon Hive (as of February 2013):

IF, HAVING, WHERE, SELECT, UNIQUEJOIN, JOIN, ON, TRANSFORM, MAP, REDUCE, TABLESAMPLE, CAST, FUNCTION, EXTENDED, CASE, WHEN, THEN, ELSE, END, DATABASE, CROSS

You can also use showdialog

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                      Handles Button3.Click

     dim mydialogbox as new aboutbox1
     aboutbox1.showdialog()

End Sub

Is there any advantage in creating a temporary file in a more careful way

The temporary files are usually created in the temporary directory (such as /tmp) where all other users and processes has read and write access (any other script can create the new files there). Therefore the script should be careful about creating the files such as using with the right permissions (e.g. read only for the owner, see: help umask) and filename should be be not easily guessed (ideally random). Otherwise if the filenames aren't unique, it can create conflict with the same script ran multiple times (e.g. race condition) or some attacker could either hijack some sensitive information (e.g. when permissions are too open and filename is easy to guess) or create/replacing the file with their own version of the code (like replacing the commands or SQL queries depending on what is being stored).

You could use the following approach to create the temporary directory:

TMPDIR=".${0##*/}-$$" && mkdir -v "$TMPDIR"

or temporary file:

TMPFILE=".${0##*/}-$$" && touch "$TMPFILE"

However it is still predictable and not considered safe.

As per man mktemp, we can read:

Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win.

So to be safe, it is recommended to use mktemp command to create unique temporary file or directory (-d).

You module and class AthleteList have the same name. Change:

import AthleteList

to:

from AthleteList import AthleteList

This now means that you are importing the module object and will not be able to access any module methods you have in AthleteList

According to AWS documentation [https://aws.amazon.com/premiumsupport/knowledge-center/instance-store-vs-ebs/] instance store volumes is not persistent through instance stops, terminations, or hardware failures. Any AMI created from instance stored disk doesn't contain data present in instance store so all instances launched by this AMI will not have data stored in instance store. Instance store can be used as cache for applications running on instance, for all persistent data you should use EBS.

Just sharing what worked in my case as someone else might find it useful. I have a modal and just wanted to print the body of the modal which could be several pages on paper.

Other solutions I tried just printed one page and only what was on screen. Emil's accepted solution worked for me:

https://stackoverflow.com/a/30137174/3123109

This is what the component ended up looking like. It prints everything in the body of the modal.

import React, { Component } from 'react';
import {
    Button,
    Modal,
    ModalBody,
    ModalHeader
} from 'reactstrap';

export default class TestPrint extends Component{
    constructor(props) {
        super(props);
        this.state = {
            modal: false,
            data: [

        var pri = document.getElementById('ifmcontentstoprint').contentWindow;
        pri.document.open();
        pri.document.write(content.innerHTML);
        pri.document.close();
        pri.focus();
        pri.print();
    }

    renderContent() {
        var i = 0;
        return this.state.data.map((d) => {
            return (<p key={d + i++}>{i} - {d}</p>)
        });
    }

    toggle() {
        this.setState({
            modal: !this.state.modal
        })
    }

    render() {
        return (
            <div>
                <Button 
                    style={

                </Modal>
            </div>
        )
    }
}

Note: However, I am having difficulty getting styles to be reflected in the iframe.

After running around in the Preferences dialog, the following is the location at which the highlight color for "occurrences" can be changed:

General -> Editors -> Text Editors -> Annotations

Look for Occurences from the Annotation types list.

Then, be sure that Text as highlighted is selected, then choose the desired color.

There is also proc.time()

You can use in the same way as Sys.time but it gives you a similar result to system.time.

ptm <- proc.time()
#your function here
proc.time() - ptm

the main difference between using

system.time({ #your function here })

is that the proc.time() method still does execute your function instead of just measuring the time... and by the way, I like to use system.time with {} inside so you can put a set of things...

Most Secure Solution, JS only

As mentioned by alko989, there is a major security flaw with _blank (details here).

To avoid it from pure JS code:

const openInNewTab = (url) => {
  const newWindow = window.open(url, '_blank', 'noopener,noreferrer')
  if (newWindow) newWindow.opener = null
}

Then add to your onClick

onClick={() => openInNewTab('https://stackoverflow.com')}

The third param can also take these optional values, based on your needs.

Combination of two previous answers:

var selected = [];
$('#checkboxes input:checked').each(function() {
    selected.push($(this).attr('name'));
});

I came across this post and found that none of the answers fully captured what I was trying to do. I have a laptop that has a 3840x2160 resolution and two monitors with 1920x1080 resolution. In order to get the correct monitor size in my WPF application I had to make the application DPI aware. Then I used the Win32 API to get the monitor size.

I did this by first moving the window to the monitor that I wanted to get the size from. Then by getting the hwnd of the application's MainWindow (doesn't have to be the main window but my application only has one window) and an IntPtr to the monitor. Then I created a new instance of the MONITORINFOEX struct and called the GetMonitorInfo method.

The MONITORINFOEX struct has both the working area and the full resolution of the screen so you can return whichever one you need. This will also allow you to leave out a reference to System.Windows.Forms (assuming you don't need it something else in your application). I used the .NET Framework Reference Source for System.Windows.Forms.Screen to come up with this solution.

public System.Drawing.Size GetMonitorSize()
{
    var window = System.Windows.Application.Current.MainWindow;
    var hwnd = new WindowInteropHelper(window).EnsureHandle();
    var monitor = NativeMethods.MonitorFromWindow(hwnd, NativeMethods.MONITOR_DEFAULTTONEAREST);
    NativeMethods.MONITORINFO info = new NativeMethods.MONITORINFO();
    NativeMethods.GetMonitorInfo(new HandleRef(null, monitor), info);
    return info.rcMonitor.Size;
}

internal static class NativeMethods
{
    public const Int32 MONITOR_DEFAULTTONEAREST = 0x00000002;

    [DllImport("user32.dll")]
    public static extern IntPtr MonitorFromWindow(IntPtr handle, Int32 flags);

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern bool GetMonitorInfo(HandleRef hmonitor, MONITORINFO info);
    
    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto, Pack = 4)]
    public class MONITORINFO
    {
        internal int cbSize = Marshal.SizeOf(typeof(MONITORINFO));
        internal RECT rcMonitor = new RECT();
        internal RECT rcWork = new RECT();
        internal int dwFlags = 0;
    }

    [StructLayout(LayoutKind.Sequential)]
    public struct RECT
    {
        public int left;
        public int top;
        public int right;
        public int bottom;

        public RECT(int left, int top, int right, int bottom)
        {
            this.left = left;
            this.top = top;
            this.right = right;
            this.bottom = bottom;
        }

        public RECT(System.Drawing.Rectangle r)
        {
            left = r.Left;
            top = r.Top;
            right = r.Right;
            bottom = r.Bottom;
        }

        public static RECT FromXYWH(int x, int y, int width, int height) => new RECT(x, y, x + width, y + height);

        public System.Drawing.Size Size => new System.Drawing.Size(right - left, bottom - top);
    }
}

$('#input').on('keyup', function() {
     var RegExpression = /^[a-zA-Z\s]*$/;

\s will allow the space

Perhaps you could think about the problem in a different way. WebClient and HttpClient are essentially different implementations of the same thing. What I recommend is implementing the Dependency Injection pattern with an IoC Container throughout your application. You should construct a client interface with a higher level of abstraction than the low level HTTP transfer. You can write concrete classes that use both WebClient and HttpClient, and then use the IoC container to inject the implementation via config.

What this would allow you to do would be to switch between HttpClient and WebClient easily so that you are able to objectively test in the production environment.

So questions like:

Will HttpClient be a better design choice if we upgrade to .Net 4.5?

Can actually be objectively answered by switching between the two client implementations using the IoC container. Here is an example interface that you might depend on that doesn't include any details about HttpClient or WebClient.

HttpClient Implementation

You can use Task.Run to make WebClient run asynchronously in its implementation.

Dependency Injection, when done well helps alleviate the problem of having to make low level decisions upfront. Ultimately, the only way to know the true answer is try both in a live environment and see which one works the best. It's quite possible that WebClient may work better for some customers, and HttpClient may work better for others. This is why abstraction is important. It means that code can quickly be swapped in, or changed with configuration without changing the fundamental design of the app.

BTW: there are numerous other reasons that you should use an abstraction instead of directly calling one of these low-level APIs. One huge one being unit-testability.

Old Answer it is kind of confusing. It gives you the LOCATIONS (all of them) of where your statment is true.

so:

>>> a = np.arange(100)
>>> np.where(a > 30)
(array([31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47,
       48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64,
       65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81,
       82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98,
       99]),)
>>> np.where(a == 90)
(array([90]),)

a = a*40
>>> np.where(a > 1000)
(array([26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42,
       43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59,
       60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76,
       77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93,
       94, 95, 96, 97, 98, 99]),)
>>> a[25]
1000
>>> a[26]
1040

I use it as an alternative to list.index(), but it has many other uses as well. I have never used it with 2D arrays.

http://docs.scipy.org/doc/numpy/reference/generated/numpy.where.html

New Answer It seems that the person was asking something more fundamental.

The question was how could YOU implement something that allows a function (such as where) to know what was requested.

First note that calling any of the comparison operators do an interesting thing.

a > 1000
array([False, False, False, False, False, False, False, False, False,
       False, False, False, False, False, False, False, False, False,
       False, False, False, False, False, False, False, False,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True`,  True,  True,  True,  True,  True,  True,  True,  True,  True], dtype=bool)`

This is done by overloading the "__gt__" method. For instance:

>>> class demo(object):
    def __gt__(self, item):
        print item


>>> a = demo()
>>> a > 4
4

As you can see, "a > 4" was valid code.

You can get a full list and documentation of all overloaded functions here: http://docs.python.org/reference/datamodel.html

Something that is incredible is how simple it is to do this. ALL operations in python are done in such a way. Saying a > b is equivalent to a.gt(b)!

You can use this code snipped to show text with ellipsis

Text(
    "Introduction to Very very very long text",
    maxLines: 1,
    overflow: TextOverflow.ellipsis,
    softWrap: false,
    style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold),
),

Why not Process.Start(@"c:\test");?

Based on Ivan Laharnar with less code and simplier:

declare
    lastSeq number;
begin
    SELECT MAX(ID) + 1 INTO lastSeq FROM <TABLE_NAME>;
    if lastSeq IS NULL then lastSeq := 1; end if;
    execute immediate 'CREATE SEQUENCE <SEQUENCE_NAME> INCREMENT BY 1 START WITH ' || lastSeq || ' MAXVALUE 999999999 MINVALUE 1 NOCACHE';
end;

It is very simple to update using Inner join query in SQL .You can do it without using FROM clause. Here is an example :

    UPDATE customer_table c 

      INNER JOIN  
          employee_table e
          ON (c.city_id = e.city_id)  

    SET c.active = "Yes"

    WHERE c.city = "New york";

This library supports HTML5 postMessage and legacy browsers with resize+hash https://github.com/ternarylabs/porthole

Edit: Now in 2014, IE6/7 usage is quite low, IE8 and above all support postMessage so I now suggest to just use that.

Sadly, I've not found anything in the documentation, but you can use some workaround, for example you could write some extended function.

For example, in Python:

CREATE or REPLACE FUNCTION json_update(data json, key text, value json)
returns json
as $$
from json import loads, dumps
if key is None: return data
js = loads(data)
js[key] = value
return dumps(js)
$$ language plpython3u

and then

update test set data=json_update(data, 'a', to_json(5)) where data->>'b' = '2';

Firebase.remove() like probably most Firebase methods is asynchronous, thus you have to listen to events to know when something happened:

parent = ref.parent()
parent.on('child_removed', function (snapshot) {
    // removed!
})
ref.remove()

According to Firebase docs it should work even if you lose network connection. If you want to know when the change has been actually synchronized with Firebase servers, you can pass a callback function to Firebase.remove method:

ref.remove(function (error) {
    if (!error) {
        // removed!
    }
}

Refreshing attribute on events is a better approach than scanning value every tenth of a second...

http://jsfiddle.net/yqdcsqzz/3/

inputElement.onchange = function()
{
    this.setAttribute('value', this.value);
};

inputElement.onkeyup = function()
{
    this.setAttribute('value', this.value);
};

Indeed, the 9th byte indicates the check state of the button, but the answers above don't take into account the checkbox which enables manual configuration. This check state value is also present in this ninth byte. The real answer should thus be:

Byte value

00001001 = Manual proxy is checked

00000101 = Use automatic configuration script is checked

00000011 = Automatically detect settings is checked

When multiple checkboxes are checked, the value of the 9th byte is the result of the bitwise OR operation on the values for which the checkbox is checked.

from datetime import datetime 
from dateutil.relativedelta import relativedelta
d = datetime.now()
date = datetime.isoformat(d).split('.')[0]
d_month = datetime.today() + relativedelta(months=1)
next_month = datetime.isoformat(d_month).split('.')[0]

Sometimes you just want to hide certain file types for a specific project. In that case, you can create a folder in your project folder called .vscode and create the settings.json file in there, (i.e. .vscode/settings.json). All settings within that file will affect your current workspace only.

For example, in a TypeScript project, this is what I have used:

// Workspace settings
{
    // The following will hide the js and map files in the editor
    "files.exclude": {
        "**/*.js": true,
        "**/*.map": true
    }
}

you can chain more than 2 conditions too :

if [ \( "$1" = '--usage' \) -o \( "$1" = '' \) -o \( "$1" = '--help' \) ]
then
   printf "\033[2J";printf "\033[0;0H"

Use RelativeLayout, place your view in it, get RelativeLayout.LayoutParams object from your view and set margins as you need. Then call requestLayout() on your view. This is the only way I know.

Ok guys it can be done easy in photoshop.

Open png photo and then check image -> mode value(i had indexed color). Go image -> mode and check rgb color. Now change your color EASY.

One thing to note, if you have a log4j.properties file on your classpath you do not need to call BasicConfigurator. A description of how to configure the properties file is here.

You could pinpoint whether your IDE is causing the issue by trying to run this class from the command line with log4j.jar and log4j.properties on your classpath.

Setting or Updating of Reactive Forms Form Control values can be done using both patchValue and setValue. However, it might be better to use patchValue in some instances.

patchValue does not require all controls to be specified within the parameters in order to update/set the value of your Form Controls. On the other hand, setValue requires all Form Control values to be filled in, and it will return an error if any of your controls are not specified within the parameter.

In this scenario, we will want to use patchValue, since we are only updating user and questioning:

this.qService.editQue([params["id"]]).subscribe(res => {
  this.question = res;
  this.editqueForm.patchValue({
    user: this.question.user,
    questioning: this.question.questioning
  });
});

EDIT: If you feel like doing some of ES6's Object Destructuring, you may be interested to do this instead

const { user, questioning } = this.question;

this.editqueForm.patchValue({
  user,
  questioning
});

Ta-dah!

That is the standard way to swap two variables, yes.

Basically set up your css like:

element {
  border: 1px solid #fff;      
  transition: border .5s linear;
}

element.saved {
  border: 1px solid transparent;
}

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

There is no limit to the number of elements that you are passing to IN clause. If there are more elements it will consider it as array and then for each scan in the database it will check if it is contained in the array or not. This approach is not so scalable. Instead of using IN clause try using INNER JOIN with temp table. Refer http://www.xaprb.com/blog/2006/06/28/why-large-in-clauses-are-problematic/ for more info. Using INNER JOIN scales well as query optimizer can make use of hash join and other optimization. Whereas with IN clause there is no way for the optimizer to optimize the query. I have noticed speedup of at least 2x with this change.

Using a unique_ptr might be OK.
You then reset it to obtain an empty queue and release the memory of the first queue. As to the complexity? I'm not sure - but guess it's O(1).

Possible code:

typedef queue<int> quint;

unique_ptr<quint> p(new quint);

// ...

p.reset(new quint);  // the old queue has been destroyed and you start afresh with an empty queue

Some DBMSs support the FROM (SELECT ...) AS alias_name syntax.

Think of your two original queries as temporary tables. You can query them like so:

SELECT t1.Activity, t1."Total Amount 2009", t2."Total Amount 2008"
FROM (query1) as t1, (query2) as t2
WHERE t1.Activity = t2.Activity

A KeyError generally means the key doesn't exist. So, are you sure the path key exists?

From the official python docs:

exception KeyError

Raised when a mapping (dictionary) key is not found in the set of existing keys.

For example:

>>> mydict = {'a':'1','b':'2'}
>>> mydict['a']
'1'
>>> mydict['c']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'c'
>>>

So, try to print the content of meta_entry and check whether path exists or not.

>>> mydict = {'a':'1','b':'2'}
>>> print mydict
{'a': '1', 'b': '2'}

Or, you can do:

>>> 'a' in mydict
True
>>> 'c' in mydict
False

Just subtract the string address from what strchr returns:

char *string = "qwerty";
char *e;
int index;

e = strchr(string, 'e');
index = (int)(e - string);

Note that the result is zero based, so in above example it will be 2.

You could achieve that simply by wrapping the image by a <div> and adding overflow: hidden to that element:

<div class="img-wrapper">
    <img src="..." />
</div>

.img-wrapper {
    display: inline-block; /* change the default display type to inline-block */
    overflow: hidden;      /* hide the overflow */
}

WORKING DEMO.

Also it's worth noting that <img> element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px gap at the bottom of the image.

That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align property to the image with a value other than baseline.

Additionally for a better user experience, you could add transition to the images.

Thus we'll end up with the following:

.img-wrapper img {
    transition: all .2s ease;
    vertical-align: middle;
}

UPDATED DEMO.

Isn't this maybe the most elegant?

REPLACE 
INTO component_psar (tbl_id, row_nr, col_1, col_2, col_3, col_4, col_5, col_6, unit, add_info, fsar_lock) 
VALUES('2', '1', '1', '1', '1', '1', '1', '1', '1', '1', 'N')

see: http://dev.mysql.com/doc/refman/5.7/en/replace.html

Try this:

    list.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1,
            int arg2, long arg3)
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {

    }
});

listA.Any(_ => listB.Contains(_))

:)

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

If you want to run a few scripts, you can use Set-executionpolicy -ExecutionPolicy Unrestricted and then reset with Set-executionpolicy -ExecutionPolicy Default.

Note that execution policy is only checked when you start its execution (or so it seems) and so you can run jobs in the background and reset the execution policy immediately.

# Check current setting
Get-ExecutionPolicy

# Disable policy
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
# Choose [Y]es

Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 example.com | tee ping__example.com.txt }
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 google.com  | tee ping__google.com.txt  }

# Can be run immediately
Set-ExecutionPolicy -ExecutionPolicy Default
# [Y]es

Recovering stashes that were cleared/dropped erroneously
   If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
   following incantation to get a list of stashes that are still in your repository, but not reachable any more:

       git fsck --unreachable |
       grep commit | cut -d\  -f3 |
       xargs git log --merges --no-walk --grep=WIP

This helped me better than the accepted answer with the same scenario.

PSFTP -b path/file_name.sftp user@IP_server -hostkey 1e:52:b1... -pw password

the file content is:

lcd "path_file for send"

cd path_destination

mput file_name_to_send

quit

to have the hostkey run:

psftp  user@IP_SERVER

You asked WHY, not how to cheat it:

Usually because of laziness of programmers of the initial implementation, because they HAVE already put way more effort in other features, delivering more odd side-effects like floats, because they were more requested by designers back then and yet they haven't taken the time to allow this so we can use the FOUR properties to push/pull an element against its neighbors (now we only have four to push, and only 2 to pull).

When html was designed, magazines loved text reflown around images back then, now hated because today we have touch trends, and love squary things with lots of space and nothing to read. That's why they put more pressure on floats than on centering, or they could have designed something like margin-top: fill; or margin: average 0; to simply align the content to the bottom, or distribute its extra space around.

In this case I think it hasn't been implemented because of the same reason that makes CSS to lack of a :parent pseudo-selector: To prevent looping evaluations.

Without being an engineer, I can see that CSS right now is made to paint elements once, remember some properties for future elements to be painted, but NEVER going back to already-painted elements.

That's why (I guess) padding is calculated on the width, because that's the value that was available at the time of starting to paint it.

If you had a negative value for padding, it would affect the outer limits, which has ALREADY been defined when the margin has already been set. I know, nothing has been painted yet, but when you read how the painting process goes, created by geniuses with 90's technology, I feel like I am asking dumb questions and just say "thanks" hehe.

One of the requirements of web pages is that they are quickly available, unlike an app that can take its time and eat the computer resources to get everything correct before displaying it, web pages need to use little resources (so they are fit in every device possible) and be scrolled in a breeze.

If you see applications with complex reflowing and positioning, like InDesign, you can't scroll that fast! It takes a big effort both from processors and graphic card to jump to next pages!

So painting and calculating forward and forgetting about an element once drawn, for now it seems to be a MUST.

If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.

Per the jQuery documentation:

Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".

You can handle your error accordingly then.

I created this fiddle that demonstrates this.

$.ajax({
    url: "/ajax_json_echo/",
    type: "GET",
    dataType: "json",
    timeout: 1000,
    success: function(response) { alert(response); },
    error: function(xmlhttprequest, textstatus, message) {
        if(textstatus==="timeout") {
            alert("got timeout");
        } else {
            alert(textstatus);
        }
    }
});?

With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.

Hope this helps!

This website contains a much cleaner solution, it leaves pip intact as-well and one can easily switch between 3.5 and 3.6 and then whenever 3.7 is released.

http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/

A short summary:

sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Then

$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

Then to select python 3.6 run

sudo update-alternatives --config python3

and select '2'. Then

$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To update pip select the desired version and

pip3 install --upgrade pip

$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Tested on Ubuntu 16.04.

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

Just in case anyone got to a desperate point where nothing works... It happened to us that the content assist somehow shrunk so no suggestion was shown, just the "Press Ctrl+Space for non-Java..." could be seen. So, it was just a matter of dragging the corner of the content assist to enlarge the pop-up.

I know, embarrassing. Hope it helps.

Note: this was an Ubuntu server with Xfce4 using Eclipse Oxygen.

To Send bold,italic,fixed width code you can use this :

# Sending a HTML formatted message
bot.send_message(chat_id=@yourchannelname, 
             text="*boldtext* _italictext_ `fixed width font` [link]   (http://google.com).", 
             parse_mode=telegram.ParseMode.MARKDOWN)

make sure you have enabled the bot as your admin .Then only it can send message

In my case PDFGenerator was producing an info.plist file, I just deleted it.

Actually it's best to use:

IF DB_ID('dms') IS NOT NULL
   --code mine :)
   print 'db exists'

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

This is what I am using:

$("#search_code").live('change', function(){
  alert(this.value)
});

For latest jQuery users, this one should work:

$(document.body).on("change","#search_code",function(){
 alert(this.value);
});

There is a simple work around. The alert only comes up when you have a large amount of data in your clipboard. Just copy a random cell before you close the workbook and it won't show up anymore!

It's an old post, with already good answers, but I add my two bits. I don't like to use console.log, I'd rather use a logger that logs to the console, or wherever I want, so I have a module defining a log function a bit like this one

function log(...args) {
  console.log(...args);
  chrome.extension.getBackgroundPage().console.log(...args);
}

When I call log("this is my log") it will write the message both in the popup console and the background console.

The advantage is to be able to change the behaviour of the logs without having to change the code (like disabling logs for production, etc...)

Set your header and footer position to "absolute" and that should do the trick. Hope it helps and good luck with your project!

I had a simple code for Spring Cloud Config

like this:

In application.properties

spring.data.mongodb.db2=mongodb://[email protected]

read

@Bean(name = "mongoConfig")
@ConfigurationProperties(prefix = "spring.data.mongodb")
public Map<String, Map<String, String>> mongoConfig() {
    return new HashMap();
}

use

@Autowired
@Qualifier(value = "mongoConfig")
private Map<String, String> mongoConfig;

@Bean(name = "mongoTemplates")
public HashMap<String, MongoTemplate> mongoTemplateMap() throws UnknownHostException {
    HashMap<String, MongoTemplate> mongoTemplates = new HashMap<>();
    for (Map.Entry<String, String>> entry : mongoConfig.entrySet()) {
        String k = entry.getKey();
        String v = entry.getValue();
        MongoTemplate template = new MongoTemplate(new SimpleMongoDbFactory(new MongoClientURI(v)));
        mongoTemplates.put(k, template);
    }
    return mongoTemplates;
}

If you want to center the content horizontally and vertically, but don't know in prior how high your page will be, you have to you use JavaScript.

HTML:

<body>
    <div id="content">...</div>
</body>

CSS:

#content {
    max-width: 1000px;
    margin: auto;
    left: 1%;
    right: 1%;
    position: absolute;
}

JavaScript (using jQuery):

$(function() {
    $(window).on('resize', function resize()  {
        $(window).off('resize', resize);
        setTimeout(function () {
            var content = $('#content');
            var top = (window.innerHeight - content.height()) / 2;
            content.css('top', Math.max(0, top) + 'px');
            $(window).on('resize', resize);
        }, 50);
    }).resize();
});

Well, if you want to do it using an algorithm. There are a plethora of sorting algorithms out there. If you aren't concerned too much about efficiency and more about readability and understandability. I recommend Insertion Sort. Here is the psudo code, it is trivial to translate this into java.

begin
    for i := 1 to length(A)-1 do
    begin
        value := A[i];
        j := i - 1;
        done := false;
        repeat
            { To sort in descending order simply reverse
              the operator i.e. A[j] < value }
            if A[j] > value then
            begin
                A[j + 1] := A[j];
                j := j - 1;
                if j < 0 then
                    done := true;
            end
            else
                done := true;
        until done;
        A[j + 1] := value;
    end;
end;

Assume that you have a tr row with multiple checkboxes in it, and you want to count only if the first checkbox is checked.

You can do that by giving a class to the first checkbox

For example class='mycxk' and you can count that using the filter, like this

$('.mycxk').filter(':checked').length

I did it this way based on the answers given here, I hope it helps

I prefer httpclient over Net::HTTP.

client = HTTPClient.new
puts client.get_content('http://www.example.com/index.html')

HTTParty is a good choice if you're making a class that's a client for a service. It's a convenient mixin that gives you 90% of what you need. See how short the Google and Twitter clients are in the examples.

And to answer your second question: no, I wouldn't put this functionality in a controller--I'd use a model instead if possible to encapsulate the particulars (perhaps using HTTParty) and simply call it from the controller.

The following VBA code should get you started. It will copy all of the data in the original workbook to a new workbook, but it will have added 1 to each value, and all blank cells will have been ignored.

Option Explicit

Public Sub exportDataToNewBook()
    Dim rowIndex As Integer
    Dim colIndex As Integer
    Dim dataRange As Range
    Dim thisBook As Workbook
    Dim newBook As Workbook
    Dim newRow As Integer
    Dim temp

    '// set your data range here
    Set dataRange = Sheet1.Range("A1:B100")

    '// create a new workbook
    Set newBook = Excel.Workbooks.Add

    '// loop through the data in book1, one column at a time
    For colIndex = 1 To dataRange.Columns.Count
        newRow = 0
        For rowIndex = 1 To dataRange.Rows.Count
            With dataRange.Cells(rowIndex, colIndex)

            '// ignore empty cells
            If .value <> "" Then
                newRow = newRow + 1
                temp = doSomethingWith(.value)
                newBook.ActiveSheet.Cells(newRow, colIndex).value = temp
                End If

            End With
        Next rowIndex
    Next colIndex
End Sub

Private Function doSomethingWith(aValue)

    '// This is where you would compute a different value
    '// for use in the new workbook
    '// In this example, I simply add one to it.
    aValue = aValue + 1

    doSomethingWith = aValue
End Function

In this LIVE DEMO i've achieved this by using the :before css selector which seems to work quite nicely.

<div class="myDiv">this is my div with multiple colours. It work's with text too!</div>

I thought i would add this as I feel it could work quite well for a percentage bar/visual level of something.

It also means you're not creating multiple divs if you don't have to, and keeps this page up-to-date

You can't do without transaction logs in SQL Server, under any circumstances. The engine simply won't function.

You CAN set your recovery model to SIMPLE on your dev machines - that will prevent transaction log bloating when tran log backups aren't done.

ALTER DATABASE MyDB SET RECOVERY SIMPLE;

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

     <staticContent>
      <remove fileExtension=".woff"/>
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />

I don't think there is a way to tell which program to use from just the .db extension. It could even be an encrypted database which can't be opened. You can MS Access, or a sqlite manager.

Edit: Try to rename the file to .txt and open it with a text editor. The first couple of words in the file could tell you the DB Type.

If it is a SQLite database, it will start with "SQLite format 3"

I have had to unpack a .ab-file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab-file is password-protected.

Usage:

java -jar abe.jar [-debug] [-useenv=yourenv] unpack <backup.ab> <backup.tar> [password]

Example:

Let's say, you've got a file test.ab, which is not password-protected, you're using Windows and want the resulting .tar-Archive to be called test.tar. Then your command should be:

java.exe -jar abe.jar unpack test.ab test.tar ""

Although @Remus Rusanu's is already an excelent answer, in case one is looking forward a better insight on SQL Server's Deadlock causes and trace strategies, I would suggest you to read Brad McGehee's How to Track Down Deadlocks Using SQL Server 2005 Profiler

If you are using security annotation from the SensioFrameworkExtraBundle, you can use a few expressions (that are defined in \Symfony\Component\Security\Core\Authorization\ExpressionLanguageProvider):

• @Security("is_authenticated()"): to check that the user is authed and not anonymous
• @Security("is_anonymous()"): to check if the current user is the anonymous user
• @Security("is_fully_authenticated()"): equivalent to is_granted('IS_AUTHENTICATED_FULLY')
• @Security("is_remember_me()"): equivalent to is_granted('IS_AUTHENTICATED_REMEMBERED')

I think the regex / string parsing solutions are great, but for this particular context, it seems like it would make sense just to use java's url parser:

https://docs.oracle.com/javase/tutorial/networking/urls/urlInfo.html

Taken from that page:

import java.net.*;
import java.io.*;

public class ParseURL {
    public static void main(String[] args) throws Exception {

        URL aURL = new URL("http://example.com:80/docs/books/tutorial"
                           + "/index.html?name=networking#DOWNLOADING");

        System.out.println("protocol = " + aURL.getProtocol());
        System.out.println("authority = " + aURL.getAuthority());
        System.out.println("host = " + aURL.getHost());
        System.out.println("port = " + aURL.getPort());
        System.out.println("path = " + aURL.getPath());
        System.out.println("query = " + aURL.getQuery());
        System.out.println("filename = " + aURL.getFile());
        System.out.println("ref = " + aURL.getRef());
    }
}

yields the following:

protocol = http
authority = example.com:80
host = example.com
port = 80
path = /docs/books/tutorial/index.html
query = name=networking
filename = /docs/books/tutorial/index.html?name=networking
ref = DOWNLOADING

Hey I just wrote it.

Now you can use <div style="color: red; @media (max-width: 200px) { color: green }"> or so.

Enjoy.

This worked for me. No need to exclude anything. I just used mockito-core instead mockito-all

testCompile 'junit:junit:4.12'
testCompile group: 'org.mockito', name: 'mockito-core', version: '3.0.0'
testCompile group: 'org.hamcrest', name: 'hamcrest-library', version: '2.1'

Starting with the given:

• There are 72 points in an inch (that is what a point is, 1/72 of an inch)
• on a system set for 150dpi, there are 150 pixels per inch.
• 1 in = 72pt = 150px (for 150dpi setting)

If you want to find points (pt) based on pixels (px):

 72 pt    x pt
------ = -----                  (1) for 150dpi system
150 px    y px

Rearranging:

x = (y/150) * 72                (2) for 150dpi system

so:

points = (pixels / 150) * 72    (3) for 150dpi system

Output of git push when pushing a new branch

> git checkout -b new_branch
Switched to a new branch 'new_branch'
> git push
fatal: The current branch new_branch has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin new_branch

A simple git push assumes that there already exists a remote branch that the current local branch is tracking. If no such remote branch exists, and you want to create it, you must specify that using the -u (short form of --set-upstream) flag.

Why this is so? I guess the implementers felt that creating a branch on the remote is such a major action that it should be hard to do it by mistake. git push is something you do all the time.

"Isn't a branch a new change to be pushed by default?" I would say that "a change" in Git is a commit. A branch is a pointer to a commit. To me it makes more sense to think of a push as something that pushes commits over to the other repositories. Which commits are pushed is determined by what branch you are on and the tracking relationship of that branch to branches on the remote.

You can read more about tracking branches in the Remote Branches chapter of the Pro Git book.

<input type="name" placeholder="First Name" title="First Name" />

title="First Name" solves my proble. it worked with bootstrap.

It's the term slug you want.Looks like you can get the id like this if that's what you need:

function get_term_link( $term, $taxonomy = '' ) {
    global $wp_rewrite;

    if ( !is_object($term) ) {
        if ( is_int( $term ) ) {
            $term = get_term( $term, $taxonomy );
        } else {
            $term = get_term_by( 'slug', $term, $taxonomy );
        }
    }

Not that anyone would ever have CAPS on when entering a password...but it can give this error.

try this one, it might be helpful for you

String arr= "[1,2]";
int[] arr=Stream.of(str.replaceAll("[\\[\\]\\, ]", "").split("")).mapToInt(Integer::parseInt).toArray();

you can use enum constructor for enum to have primitive data type..

public enum DaysOfWeek {
    MONDAY(1),
    TUESDAY(2),
    WEDNESDAY(3),
    THURSDAY(4),
    FRIDAY(5),
    SATURDAY(6),
    SUNDAY(7);

    private int value;
    private DaysOfWeek(int value) {
        this.value = value;
    }

    public int getValue() {
        return this.value;
    }

    private static final SparseArray<DaysOfWeek> map = new SparseArray<DaysOfWeek>();

    static
    {
         for (DaysOfWeek daysOfWeek : DaysOfWeek.values())
              map.put(daysOfWeek.value, daysOfWeek);
    }

    public static DaysOfWeek from(int value) {
        return map.get(value);
    }
}

you can use to pass int as extras then pull it from enum using its value.

This doesn't require jQuery. The JavaScript Math.random function returns a random number between 0 and 1, so if you want a number between 1 and 6, you can do:

var number = 1 + Math.floor(Math.random() * 6);

Update: (as per comment) If you want to display a random number that changes every so often, you can use setInterval to create a timer:

setInterval(function() {
  var number = 1 + Math.floor(Math.random() * 6);
  $('#my_div').text(number);
},
1000); // every 1 second

Warning: this is a dangerous method! It abuses the i/o buffers in linux and with specific options of buffering it manages to work on small files. It is an interesting curiosity. But don't use it for a real situation!

Besides the -i option of sed you can use the tee utility.

From man:

tee - read from standard input and write to standard output and files

So, the solution would be:

sed s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g index.html | tee | tee index.html

-- here the tee is repeated to make sure that the pipeline is buffered. Then all commands in the pipeline are blocked until they get some input to work on. Each command in the pipeline starts when the upstream commands have written 1 buffer of bytes (the size is defined somewhere) to the input of the command. So the last command tee index.html, which opens the file for writing and therefore empties it, runs after the upstream pipeline has finished and the output is in the buffer within the pipeline.

Most likely the following won't work:

sed s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g index.html | tee index.html

-- it will run both commands of the pipeline at the same time without any blocking. (Without blocking the pipeline should pass the bytes line by line instead of buffer by buffer. Same as when you run cat | sed s/bar/GGG/. Without blocking it's more interactive and usually pipelines of just 2 commands run without buffering and blocking. Longer pipelines are buffered.) The tee index.html will open the file for writing and it will be emptied. However, if you turn the buffering always on, the second version will work too.

You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});

No, there isn't. But you shouldn't rely on this if this is related to a security question.
