"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

String Constants

Just use the + operator and break the string up into human-readable lines. The compiler will pick up that the strings are constant and concatenate them at compile time. See the MSDN C# Programming Guide here.

e.g.

const string myVeryLongString = 
    "This is the opening paragraph of my long string. " +
    "Which is split over multiple lines to improve code readability, " +
    "but is in fact, just one long string.";

IL_0003: ldstr "This is the opening paragraph of my long string. Which is split over multiple lines to improve code readability, but is in fact, just one long string."

String Variables

Note that when using string interpolation to substitute values into your string, that the $ character needs to precede each line where a substitution needs to be made:

var interpolatedString = 
    "This line has no substitutions. " +
    $" This line uses {count} widgets, and " +
    $" {CountFoos()} foos were found.";

However, this has the negative performance consequence of multiple calls to string.Format and eventual concatenation of the strings (marked with ***)

IL_002E:  ldstr       "This line has no substitutions. "
IL_0033:  ldstr       " This line uses {0} widgets, and "
IL_0038:  ldloc.0     // count
IL_0039:  box         System.Int32
IL_003E:  call        System.String.Format ***
IL_0043:  ldstr       " {0} foos were found."
IL_0048:  ldloc.1     // CountFoos
IL_0049:  callvirt    System.Func<System.Int32>.Invoke
IL_004E:  box         System.Int32
IL_0053:  call        System.String.Format ***
IL_0058:  call        System.String.Concat ***

Although you could either use $@ to provide a single string and avoid the performance issues, unless the whitespace is placed inside {} (which looks odd, IMO), this has the same issue as Neil Knight's answer, as it will include any whitespace in the line breakdowns:

var interpolatedString = $@"When breaking up strings with `@` it introduces
    <- [newLine and whitespace here!] each time I break the string.
    <- [More whitespace] {CountFoos()} foos were found.";

The injected whitespace is easy to spot:

IL_002E:  ldstr       "When breaking up strings with `@` it introduces
    <- [newLine and whitespace here!] each time I break the string.
    <- [More whitespace] {0} foos were found."

An alternative is to revert to string.Format. Here, the formatting string is a single constant as per my initial answer:

const string longFormatString = 
    "This is the opening paragraph of my long string with {0} chars. " +
    "Which is split over multiple lines to improve code readability, " +
    "but is in fact, just one long string with {1} widgets.";

And then evaluated as such:

string.Format(longFormatString, longFormatString.Length, CountWidgets());

However this can still be tricky to maintain given the potential separation between the formatting string and the substitution tokens.

None of the above solutions were suitable for my scenario, handling .Navigated and .FileDownload events seemed like a good fit but accessing the WebBrowser.Document property threw an UnauthorizedAccessException which is caused by cross frame scripting security (our web content contains frames - all on the same domain/address but frames have their own security holes that are being blocked).

The solution that worked was to override IOleCommandTarget and to catch the script error commands at that level. Here's the WebBrowser sub-class to achieve this:

I used the backgroundTint and foreground:

    android:backgroundTint="@color/colorAccent"
    android:foreground="?android:attr/selectableItemBackground"
    android:textColor="@android:color/white"
    android:textSize="10sp"/>

I like this:

  "scripts": {
    "??? Jenkins Build - in this order ???                                                                                                  ": "",
    "purge": "lerna run something",
    "clean:test": "lerna exec --ignore nanana"
}

There are extra spaces in the command name, so in Visual Studio Code's NPM Scripts plugin you have a better look.

Suppose your class is called MyStudent. Here's how you define your class constructor:

Public Class MyStudent
    Public StudentId As Integer

    'Here's the class constructor:
    Public Sub New(newStudentId As Integer)
        StudentId = newStudentId
    End Sub
End Class

Here's how you call it:

Dim student As New MyStudent(studentId)

Of course, your class constructor can contain as many or as few arguments as you need--even none, in which case you leave the parentheses empty. You can also have several constructors for the same class, all with different combinations of arguments. These are known as different "signatures" for your class constructor.

For WebAPI, here is the code to retrieve body text without going through their special [FromBody] binding.

public class YourController : ApiController
{
    [HttpPost]
    public HttpResponseMessage Post()
    {
        string bodyText = this.Request.Content.ReadAsStringAsync().Result;
        //more code here...
    }
}

The quickest way is to switch default branch from master to another and you can remove master branch from the web interface.

For multi-line shell scripts or those run multiple times, I would create a new bash script file (starting from #!/bin/bash), and simply run it with sh from Jenkinsfile:

sh 'chmod +x ./script.sh'
sh './script.sh'

Just remove the : in your Quantity. Make sure that your attribute is the same with the parameter you include in the code, like this:

Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
    For i As Integer = 0 To Me.DataGridView1.Rows.Count - 1
        If Me.DataGridView1.Rows(i).Cells("Quantity").Value < 5 Then
            Me.DataGridView1.Rows(i).Cells("Quantity").Style.ForeColor = Color.Red
        End If
    Next
End Sub

This query works on Microsoft SQL Server.

select distinct format( cast('2010-01-01' as datetime) + ( a.v / 10 ), 'yyyy-MM-dd' ) as aDate
       from (
             SELECT ones.n + 10 * tens.n + 100 * hundreds.n + 1000 * thousands.n as v
             FROM (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) ones(n),
                    (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) tens(n),
                    (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) hundreds(n),
                  (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) thousands(n)
       ) a
       where format( cast('2010-01-01' as datetime) + ( a.v / 10 ), 'yyyy-MM-dd' ) < cast('2010-01-13' as datetime)
       order by aDate asc;

Now let's look at how it works.

The inner query merely returns a list of integers from 0 to 9999. It will give us a range of 10,000 values for calculating dates. You can get more dates by adding rows for ten_thousands and hundred_thousands and so forth.

SELECT ones.n + 10 * tens.n + 100 * hundreds.n + 1000 * thousands.n as v
         FROM (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) ones(n),
                (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) tens(n),
                (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) hundreds(n),
              (VALUES(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) thousands(n)
   ) a;

This part converts the string to a date and adds a number to it from the inner query.

cast('2010-01-01' as datetime) + ( a.v / 10 )

Then we convert the result into the format you want. This is also the column name!

format( cast('2010-01-01' as datetime) + ( a.v / 10 ), 'yyyy-MM-dd' )

Next we extract only the distinct values and give the column name an alias of aDate.

distinct format( cast('2010-01-01' as datetime) + ( a.v / 10 ), 'yyyy-MM-dd' ) as aDate

We use the where clause to filter in only dates within the range you want. Notice that we use the column name here since SQL Server does not accept the column alias, aDate, within the where clause.

where format( cast('2010-01-01' as datetime) + ( a.v / 10 ), 'yyyy-MM-dd' ) < cast('2010-01-13' as datetime)

Lastly, we sort the results.

   order by aDate asc;

Java/JavaScript:

You could probably do it this way also, non-natively:

public void triggerButtonOnEnterKeyInTextField(String textFieldId, String clickableButId)
{
    ((JavascriptExecutor) driver).executeScript(
        "   elementId = arguments[0];
            buttonId = arguments[1];
            document.getElementById(elementId)

BehaviourSubject

BehaviourSubject will return the initial value or the current value on Subscription

var bSubject= new Rx.BehaviorSubject(0);  // 0 is the initial value

bSubject.subscribe({
  next: (v) => console.log('observerA: ' + v)  // output initial value, then new values on `next` triggers
});

bSubject.next(1);  // output new value 1 for 'observer A'
bSubject.next(2);  // output new value 2 for 'observer A', current value 2 for 'Observer B' on subscription

bSubject.subscribe({
  next: (v) => console.log('observerB: ' + v)  // output current value 2, then new values on `next` triggers
});

bSubject.next(3);

With output:

observerA: 0
observerA: 1
observerA: 2
observerB: 2
observerA: 3
observerB: 3

Subject

Subject does not return the current value on Subscription. It triggers only on .next(value) call and return/output the value

var subject = new Rx.Subject();

subject.next(1); //Subjects will not output this value

subject.subscribe({
  next: (v) => console.log('observerA: ' + v)
});
subject.subscribe({
  next: (v) => console.log('observerB: ' + v)
});

subject.next(2);
subject.next(3);

With the following output on the console:

observerA: 2
observerB: 2
observerA: 3
observerB: 3

PHP 7+

As of PHP 7, you can use the Unicode codepoint escape syntax to do this.

echo "\u{00ed}"; outputs í.

Within the definition of the appender, I believe you can do something like this:

<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
    <filter type="log4net.Filter.LevelRangeFilter">
        <param name="LevelMin" value="INFO"/>
        <param name="LevelMax" value="INFO"/>
    </filter>
    ...
</appender>

I am improving upon supercat's answer. I guess the following can also be done:

class Sample
{
    private readonly int _intField;
    public int IntProperty
    {
        get { return _intField; }
    }

    void setupStuff(ref int intField, int newValue)
    {
        //Do some stuff here based upon the necessary initialized variables.
        intField = newValue;
    }

    public Sample(string theIntAsString, bool? doStuff = true)
    {
        //Initialization of some necessary variables.
        //==========================================
        int i = int.Parse(theIntAsString);
        // ................
        // .......................
        //==========================================

        if (!doStuff.HasValue || doStuff.Value == true)
           setupStuff(ref _intField,i);
    }

    public Sample(int theInt): this(theInt, false) //"false" param to avoid setupStuff() being called two times
    {
        setupStuff(ref _intField, theInt);
    }
}

the most simple and straight forward is to create a FTP login. Here is a little and easy to understand tutorial site on stackoverflow itself, how to set things up in 2min... Setting up FTP on Amazon Cloud Server

You can populate the table until you have enough disk space. For better performance you can try migration to SQL Server 2005 and then partition the table and put parts on different disks(if you have RAID configuration that could really help you). Partitioning is possible only in enterprise version of SQL Server 2005. You can look partitioning example at this link: http://technet.microsoft.com/en-us/magazine/cc162478.aspx

Also you can try to create views for most used data portion, that is also one of the solutions.

Hope this helped...

Normally, I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6, I'd use JDK 6 because you would want your development environment to be as close as possible to the instructors. It would suck if you ran into an issue and having the thought in the back of your head that maybe it's because you're on JDK 7 that you're having the issue. Btw, I haven't touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you, I only code Android apps casually.

Here is the one-liner version getting the client's IP address:

$ip = @$_SERVER['HTTP_CLIENT_IP'] ?: @$_SERVER['HTTP_X_FORWARDED_FOR'] ?: @$_SERVER['REMOTE_ADDR'];

Notes:

• By using @, it suppresses the PHP notices.

• Value from HTTP_X_FORWARDED_FOR may consist multiple addresses separated by comma, so if you prefer to get the first one, you can use the following method:

  current(explode(',', @$_SERVER['HTTP_X_FORWARDED_FOR']))
  

Update for npm 5:

As of npm 5.0.0, installed/uninstalled modules are added/removed as a dependency by default, so the --save option is no longer needed.

Run

npm uninstall <package>

For example:

npm uninstall mongodb

It will remove the module from the node_modules folder and also the package.json file.

CTRL-click works anywhere

CTRL-click that brings you to where clicked object is defined works everywhere - not only in Java classes and variables in Java code, but in Spring configuration (you can click on class name, or property, or bean name), in Hibernate (you can click on property name or class, or included resource), you can navigate within one click from Java class to where it is used as Spring or Hibernate bean; clicking on included JSP or JSTL tag also works, ctrl-click on JavaScript variable or function brings you to the place it is defined or shows a menu if there are more than one place, including other .js files and JS code in HTML or JSP files.

Autocomplete for many languagues

Hibernate

Autocomplete in HSQL expressions, in Hibernate configuration (including class, property and DB column names), in Spring configuration

<property name="propName" ref="<hit CTRL-SPACE>"

and it will show you list of those beans which you can inject into that property.

Java

Very smart autocomplete in Java code:

interface Person {
    String getName();
    String getAddress();
    int getAge();
}
//---
Person p;
String name = p.<CTRL-SHIFT-SPACE>

and it shows you ONLY getName(), getAddress() and toString() (only they are compatible by type) and getName() is first in the list because it has more relevant name. Latest version 8 which is still in EAP has even more smart autocomplete.

interface Country{
}
interface Address {
    String getStreetAddress();
    String getZipCode();
    Country getCountry();
}
interface Person {
    String getName();
    Address getAddress();
    int getAge();
}
//--- 
Person p;
Country c = p.<CTRL-SHIFT-SPACE>

and it will silently autocomplete it to

Country c = p.getAddress().getCountry();

Javascript

Smart autocomplete in JavaScript.

function Person(name,address) {
    this.getName = function() { return name };
    this.getAddress = function() { return address };
}

Person.prototype.hello = function() {
    return "I'm " + this.getName() + " from " + this.get<CTRL-SPACE>;
}

and it shows ONLY getName() and getAddress(), no matter how may get* methods you have in other JS objects in your project, and ctrl-click on this.getName() brings you to where this one is defined, even if there are some other getName() functions in your project.

HTML

Did I mention autocomplete and ctrl-clicking in paths to files, like <script src="", <img src="", etc?

Autocomplete in HTML tag attributes. Autocomplete in style attribute of HTML tags, both attribute names and values. Autocomplete in class attributes as well.
Type <div class="<CTRL-SPACE> and it will show you list of CSS classes defined in your project. Pick one, ctrl-click on it and you will be redirected to where it is defined.

Easy own language higlighting

Latest version has language injection, so you can declare that you custom JSTL tag usually contains JavaScript and it will highlight JavaScript inside it.

<ui:obfuscateJavaScript>function something(){...}</ui:obfuscateJavaScript>

Indexed search across all project.

You can use Find Usages of any Java class or method and it will find where it is used including not only Java classes but Hibernate, Spring, JSP and other places. Rename Method refactoring renames method not only in Java classes but anywhere including comments (it can not be sure if string in comments is really method name so it will ask). And it will find only your method even if there are methods of another class with same name. Good source control integration (does SVN support changelists? IDEA support them for every source control), ability to create a patch with your changes so you can send your changes to other team member without committing them.

Improved debugger

When I look at HashMap in debugger's watch window, I see logical view - keys and values, last time I did it in Eclipse it was showing entries with hash and next fields - I'm not really debugging HashMap, I just want to look at it contents.

Spring & Hibernate configuration validation

It validates Spring and Hibernate configuration right when you edit it, so I do not need to restart server to know that I misspelled class name, or added constructor parameter so my Spring cfg is invalid.

Last time I tried, I could not run Eclipse on Windows XP x64.

and it will suggest you person.name or person.address. Ctrl-click on person.name and it will navigate you to getName() method of Person class.

Type Pattern.compile(""); put \\ there, hit CTRL-SPACE and see helpful hint about what you can put into your regular expression. You can also use language injection here - define your own method that takes string parameter, declare in IntelliLang options dialog that your parameter is regular expression - and it will give you autocomplete there as well. Needless to say it highlights incorrect regular expressions.

Other features

There are few features which I'm not sure are present in Eclipse or not. But at least each member of our team who uses Eclipse, also uses some merging tool to merge local changes with changes from source control, usually WinMerge. I never need it - merging in IDEA is enough for me. By 3 clicks I can see list of file versions in source control, by 3 more clicks I can compare previous versions, or previous and current one and possibly merge.

It allows to to specify that I need all .jars inside WEB-INF\lib folder, without picking each file separately, so when someone commits new .jar into that folder it picks it up automatically.

Mentioned above is probably 10% of what it does. I do not use Maven, Flex, Swing, EJB and a lot of other stuff, so I can not tell how it helps with them. But it does.

I have Android Studio version 3.1.2, it shows project full path when you click Build tab in bottom-left location of the studio.

use

=VLOOKUP(D4,F4:G9,2)

with the range F4:G9:

0   0.1
1   0.15
5   0.2
15  0.3
30  1
100 1.3

and D4 being the value in question, e.g. 18.75 -> result: 0.3

You can just pass a list of the two points you want to connect to plt.plot. To make this easily expandable to as many points as you want, you could define a function like so.

import matplotlib.pyplot as plt

x=[-1 ,0.5 ,1,-0.5]
y=[ 0.5,  1, -0.5, -1]

plt.plot(x,y, 'ro')

def connectpoints(x,y,p1,p2):
    x1, x2 = x[p1], x[p2]
    y1, y2 = y[p1], y[p2]
    plt.plot([x1,x2],[y1,y2],'k-')

connectpoints(x,y,0,1)
connectpoints(x,y,2,3)

plt.axis('equal')
plt.show()

Note, that function is a general function that can connect any two points in your list together.

To expand this to 2N points, assuming you always connect point i to point i+1, we can just put it in a for loop:

import numpy as np
for i in np.arange(0,len(x),2):
    connectpoints(x,y,i,i+1)

In that case of always connecting point i to point i+1, you could simply do:

for i in np.arange(0,len(x),2):
    plt.plot(x[i:i+2],y[i:i+2],'k-')

public TEnum ToEnum<TEnum>(this string value, TEnum defaultValue){
if (string.IsNullOrEmpty(value))
    return defaultValue;

return Enum.Parse(typeof(TEnum), value, true);}

You have to install a Selenium Server (a Hub) and register your remote WebDriver to it. Then, your client will talk to the Hub which will find a matching WebDriver to execute your test.

You can have a look at here for more information.

match returns an array.

The default string representation of an array in JavaScript is the elements of the array separated by commas. In this case the desired result is in the second element of the array:

var tesst = "afskfsd33j"
var test = tesst.match(/a(.*)j/);
alert (test[1]);

Can't pickle <type 'function'>: attribute lookup __builtin__.function failed

This error will also come if you have any inbuilt function inside the model object that was passed to the async job.

So make sure to check the model objects that are passed doesn't have inbuilt functions. (In our case we were using FieldTracker() function of django-model-utils inside the model to track a certain field). Here is the link to relevant GitHub issue.

I took Joe Love's answer and rewrote it using the IN operator with sub-selects instead of = to make the function faster (according to Hubbitus's suggestion):

Found the simple solution on

http://jasonwatmore.com/post/2014/04/18/post-a-simple-string-value-from-angularjs-to-net-web-api

return $http.post(Config.apiUrl + '/example/processfile', '"' + fileName + '"');

This is a simple STDERR function, which redirect the pipe input to STDERR.

#!/bin/bash
# *************************************************************
# This function redirect the pipe input to STDERR.
#
# @param stream
# @return string
#
function STDERR () {

cat - 1>&2

}

# remove the directory /bubu
if rm /bubu 2>/dev/null; then
    echo "Bubu is gone."
else
    echo "Has anyone seen Bubu?" | STDERR
fi


# run the bubu.sh and redirect you output
tux@earth:~$ ./bubu.sh >/tmp/bubu.log 2>/tmp/bubu.err

If you want to close tty for specific user with all the process, above command is the easiest. You can use:

killall -u user_name

If your solution requires returning 0 instead of true/false, I've found this to be useful:

PS C:\> [array]$foo = $null
PS C:\> ($foo | Measure-Object).Count
0

This operation is different from the count property of the array, because Measure-Object is counting objects. Since there are none, it will return 0.

Just do:

git push origin <your_branch_name> --force

or if you have a specific repo:

git push https://git.... --force

This will delete your previous commit(s) and push your current one.

It may not be proper, but if anyone stumbles upon this page, thought they might want a simple solution...

Short flag

Also note that -f is short for --force, so

git push origin <your_branch_name> -f

will also work.

Discovered that calling stat is slow and collects a lot of info that is not required for file existence check.
After spending some time searching for solution, i discovered following solution, which works much faster:

- raw: test -e /path/to/something && echo true || echo false
  register: file_exists

- debug: msg="Path exists"
  when: file_exists == true

This error is weird as many proposed answers and got mixed solutions. I tried them, add them. It was only when I added pip install --upgrade pip finally removed the error for me. But I have no time to isolate which is which,so this is just fyi.

-- Note that you can not use an alias over the table where you need delete

I recommend: Twisted (http://twistedmatrix.com)

an event-driven networking engine written in Python and licensed under the open source MIT license.

It's cross-platform and was preinstalled on OS X 10.5 to 10.12. Amongst other things you can start up a simple web server in the current directory with:

twistd -no web --path=.

Details

Explanation of Options (see twistd --help for more):

-n, --nodaemon       don't daemonize, don't use default umask of 0077
-o, --no_save        do not save state on shutdown

"web" is a Command that runs a simple web server on top of the Twisted async engine. It also accepts command line options (after the "web" command - see twistd web --help for more):

  --path=             <path> is either a specific file or a directory to be
                      set as the root of the web server. Use this if you
                      have a directory full of HTML, cgi, php3, epy, or rpy
                      files or any other files that you want to be served up
                      raw.

There are also a bunch of other commands such as:

conch            A Conch SSH service.
dns              A domain name server.
ftp              An FTP server.
inetd            An inetd(8) replacement.
mail             An email service
... etc

Installation

Ubuntu

sudo apt-get install python-twisted-web (or python-twisted for the full engine)

Mac OS-X (comes preinstalled on 10.5 - 10.12, or is available in MacPorts and through Pip)

sudo port install py-twisted

Windows

installer available for download at http://twistedmatrix.com/

HTTPS

Twisted can also utilise security certificates to encrypt the connection. Use this with your existing --path and --port (for plain HTTP) options.

twistd -no web -c cert.pem -k privkey.pem --https=4433

Check MySQL UNIX Socket

Find unix_socket location using MySQL

mysql -u homestead -p

mysql> show variables like '%sock%';
+-----------------------------------------+-----------------------------+
| Variable_name                           | Value                       |
+-----------------------------------------+-----------------------------+
| performance_schema_max_socket_classes   | 10                          |
| performance_schema_max_socket_instances | 322                         |
| socket                                  | /var/run/mysqld/mysqld.sock |
+-----------------------------------------+-----------------------------+
3 rows in set (0.00 sec)

Then I go to config/database.php

I update this line : 'unix_socket' => '/tmp/mysql.sock',

to : 'unix_socket' => '/var/run/mysqld/mysqld.sock',

That's it. It works for my as my 4th try.I hope these steps help someone. :D

Using collections.defaultdict is a big time-saver when you're building dicts and don't know beforehand which keys you're going to have.

Here it's used twice: for the resulting dict, and for each of the values in the dict.

import collections

def aggregate_names(errors):
    result = collections.defaultdict(lambda: collections.defaultdict(list))
    for real_name, false_name, location in errors:
        result[real_name][false_name].append(location)
    return result

Combining this with your code:

dictionary = aggregate_names(previousFunction(string))

Or to test:

EXAMPLES = [
    ('Fred', 'Frad', 123),
    ('Jim', 'Jam', 100),
    ('Fred', 'Frod', 200),
    ('Fred', 'Frad', 300)]
print aggregate_names(EXAMPLES)

I know this is a late answer, but I hope this will help someone.

Consider that you have defined following classes in a css file 'primary', 'font-i', 'font-xl'

• The first step would be to import the CSS file.
• Then

<h3 class = {` ${'primary'} ${'font-i'} font-xl`}> HELLO WORLD </h3>

would do the trick!

I found a better way than reload the page. instead i will reload the data that just got updated. this way faster n better

Tricky method:

var s = "dasdnk asd, (naks) :d skldma";
var a = s.replace('(',' ').replace(')',' ').replace(',',' ').split(' ');
console.log(a);//["dasdnk", "asd", "naks", ":d", "skldma"]

Here are two functions to get the page height and the scroll amounts (x,y) without the use of the (bloated) dimensions plugin:

// getPageScroll() by quirksmode.com
function getPageScroll() {
    var xScroll, yScroll;
    if (self.pageYOffset) {
      yScroll = self.pageYOffset;
      xScroll = self.pageXOffset;
    } else if (document.documentElement && document.documentElement.scrollTop) {
      yScroll = document.documentElement.scrollTop;
      xScroll = document.documentElement.scrollLeft;
    } else if (document.body) {// all other Explorers
      yScroll = document.body.scrollTop;
      xScroll = document.body.scrollLeft;
    }
    return new Array(xScroll,yScroll)
}

// Adapted from getPageSize() by quirksmode.com
function getPageHeight() {
    var windowHeight
    if (self.innerHeight) { // all except Explorer
      windowHeight = self.innerHeight;

Why not use: CopyOnWriteArraySet from java.util.concurrent?

Typical usage might look like:

i=0
echo -e "hello1\nhello2\nhello3" | while read str ; do
    echo "$((++i)): $str"
done

and output

1: hello1
2: hello2
3: hello3

The difference between this two tables ItemBack1 and #ItemBack1 is that the first on is persistent (permanent) where as the other is temporary.

Now if take a look at your question again

Is it necessary to Use # for creating temp table in sql server?

The answer is Yes, because without this preceding # the table will not be a temporary table, it will be independent of all sessions and scopes.

It's because you're casting to the wrong thing - you're trying to convert to a particular type, and the object that your express refers to is incompatible with that type. For example:

Object x = "this is a string";
InputStream y = (InputStream) x; // This will throw ClassCastException

If you could provide a code sample, that would really help...

I work for a company with hundreds of developers who obviously need to check Kafka messages on a regular basis. Employees come and go and therefore we want to avoid the setup (dedicated SASL credentials, certificates, ACLs, ...) for each new employee.

Our platform teams operate a deployment of Kowl (https://github.com/cloudhut/kowl) so that everyone can access it without going through the usual setup. We also use it when developing locally using a docker-compose file.

#include<stdio.h>
int main(void)
{  
int mat[10][10],i,j;

printf("Enter your matrix\n");  
for(i=0;i<2;i++)
  for(j=0;j<2;j++)
  {  
    scanf("%d",&mat[i][j]);  
  }  
printf("\nHere is your matrix:\n");   
for(i=0;i<2;i++)    
{  
    for(j=0;j<2;j++)  
    {  
      printf("%d ",mat[i][j]);  
    }  
    printf("\n");  
  }

You can't do this with jQuery, visible="false" in asp.net means the control isn't rendered into the page. If you want the control to go to the client, you need to do style="display: none;" so it's actually in the HTML, otherwise there's literally nothing for the client to show, since the element wasn't in the HTML your server sent.

If you remove the visible attribute and add the style attribute you can then use jQuery to show it, like this:

$("#elementID").show();

Old Answer (before patrick's catch)

To change visibility, you need to use .css(), like this:

$("#elem").css('visibility', 'visible');

Unless you need to have the element occupy page space though, use display: none; instead of visibility: hidden; in your CSS, then just do:

$("#elem").show();

The .show() and .hide() functions deal with display instead of visibility, like most of the jQuery functions :)

I know this question is too old, but still, I think this approach would be cleaner:

cat = $.URLDecode(cat);
$('#cbCategory option:contains("' + cat + '")').prop('selected', true);

In this case you wont need to go over the entire options with each(). Although by that time prop() didn't exist so for older versions of jQuery use attr().

UPDATE

You have to be certain when using contains because you can find multiple options, in case of the string inside cat matches a substring of a different option than the one you intend to match.

Then you should use:

cat = $.URLDecode(cat);
$('#cbCategory option')
    .filter(function(index) { return $(this).text() === cat; })
    .prop('selected', true);

Reference types do not store the object directly into the variable to which it is assigned, so the object variable in the example below, doesn’t actually contain the object instance. Instead, it holds a pointer (or reference) to the location in memory, where the object exists.

var object = new Object();

if you assign one reference typed variable to another, each variable gets a copy of the pointer, and both still reference to the same object in memory.

var object1 = new Object();
var object2 = object1;

JavaScript is a garbage-collected language, so you don’t really need to worry about memory allocations when you use reference types. However, it’s best to dereference objects that you no longer need so that the garbage collector can free up that memory. The best way to do this is to set the object variable to null.

var object1 = new Object();
// do something
object1 = null; // dereference

Dereferencing objects is especially important in very large applications that use millions of objects.

Visual Studio solutions consists of one or more projects. For Example : Console projects can produce an assembly. An assembly is logically chunk of code that can be shipped to customers, and physically an .EXE (executable program) or .DLL (are reusable by other programs).

Unfortunately neither display:inline-block nor width:0px works in Internet Explorer up to version 8. I have not tried Internet Explorer 9. Much as I would like to ignore Internet Explorer, I can't.

The only option that works on Firefox and Internet Explorer 8 is float:left. The only slight drawback is that you have to remember to use clear:both on the element that follows the form. Of course, it will be very obvious if you forget ;-)

If you're using the PageFactory pattern or already have a reference to your WebElement, then you probably want to set the attribute, using your existing reference to the WebElement. (Rather than doing a document.getElementById(...) in your javascript)

The following sample allows you to set the attribute, using your existing WebElement reference.

Code Snippet

import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.FindBy;

public class QuickTest {

    RemoteWebDriver driver;

    @FindBy(id = "foo")
    private WebElement username;

    public void exampleUsage(RemoteWebDriver driver) {
        setAttribute(username, "attr", "10");
        setAttribute(username, "value", "bar");
    }

    public void setAttribute(WebElement element, String attName, String attValue) {
        driver.executeScript("arguments[0].setAttribute(arguments[1], arguments[2]);", 
                element, attName, attValue);
    }
}

Many of these suggestions do not take into account if you run a delete statement that deletes nothing.
Say you try to delete where an ID equals some value that does not exist in the table.
Your trigger still gets called but there is nothing in the Deleted or Inserted tables.

Use this to be safe:

--Determine if this is an INSERT,UPDATE, or DELETE Action or a "failed delete".
DECLARE @Action as char(1);
    SET @Action = (CASE WHEN EXISTS(SELECT * FROM INSERTED)
                         AND EXISTS(SELECT * FROM DELETED)
                        THEN 'U'  -- Set Action to Updated.
                        WHEN EXISTS(SELECT * FROM INSERTED)
                        THEN 'I'  -- Set Action to Insert.
                        WHEN EXISTS(SELECT * FROM DELETED)
                        THEN 'D'  -- Set Action to Deleted.
                        ELSE NULL -- Skip. It may have been a "failed delete".   
                    END)

Special thanks to @KenDog and @Net_Prog for their answers.
I built this from their scripts.

As the definition of Linkedlist says, it is a sequence and you are guaranteed to get the elements in order.

eg:

import java.util.LinkedList;

public class ForEachDemonstrater {
  public static void main(String args[]) {
    LinkedList<Character> pl = new LinkedList<Character>();
    pl.add('j');
    pl.add('a');
    pl.add('v');
    pl.add('a');
    for (char s : pl)
      System.out.print(s+"->");
  }
}

You can also try the randomcoloR package:

library(randomcoloR)
n <- 20
palette <- distinctColorPalette(n)

You can see that a set of highly distinct colors are chosen when visualizing in a pie chart (as suggested by other answers here):

pie(rep(1, n), col=palette)

Shown in a pie chart with 50 colors:

n <- 50
palette <- distinctColorPalette(n)
pie(rep(1, n), col=palette)

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

You can display the name of a variable by using the preprocessor. For instance

#include <iostream>
#define quote(x) #x
class one {};
int main(){
    one A;
    std::cout<<typeid(A).name()<<"\t"<< quote(A) <<"\n";
    return 0;
}

outputs

3one    A

on my machine. The # changes a token into a string, after preprocessing the line is

std::cout<<typeid(A).name()<<"\t"<< "A" <<"\n";

Of course if you do something like

void foo(one B){
    std::cout<<typeid(B).name()<<"\t"<< quote(B) <<"\n";
}
int main(){
    one A;
    foo(A);
    return 0;
}

you will get

3one B

as the compiler doesn't keep track of all of the variable's names.

As it happens in gcc the result of typeid().name() is the mangled class name, to get the demangled version use

#include <iostream>
#include <cxxabi.h>
#define quote(x) #x
template <typename foo,typename bar> class one{ };
int main(){
    one<int,one<double, int> > A;
    int status;
    char * demangled = abi::__cxa_demangle(typeid(A).name(),0,0,&status);
    std::cout<<demangled<<"\t"<< quote(A) <<"\n";
    free(demangled);
    return 0;
}

which gives me

one<int, one<double, int> > A

Other compilers may use different naming schemes.

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

%TIME% is in the format H:MM:SS,CS after midnight and hence conversion to centiseconds >doesn't work. Seeing Patrick Cuff's post with 6:46am it seems that it is not only me.

But with this lines bevor you should will fix that problem easy:

if " "=="%StartZeit:~0,1%" set StartZeit=0%StartZeit:~-10%
if " "=="%EndZeit:~0,1%" set EndZeit=0%EndZeit:~-10%

using (var enumerator = myMoney.GetEnumerator())
{
    while (enumerator.MoveNext())
    {
        var element = enumerator.Current;
        Console.WriteLine(element.amount);
    }

You can do

[5, 10].min

or

[4, 7].max

They come from the Enumerable module, so anything that includes Enumerable will have those methods available.

v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.

@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].

[4, 5, 7, 10].minmax
=> [4, 10]

def base_conversion(num, base):
    digits = []
    while num > 0:
        num, remainder = divmod(num, base)
        digits.append(remainder)
    return digits[::-1]

I have experimented many of the backslash escape characters. \n which is a new line feed can be put anywhere to bring the effect. One important thing to remember while using this character is that the operating system of the machine we are using might affect the output. As an example, I have printed a bunch of escape character and displayed the result as follow to proof that the OS will affect the output.

Code:

#include <stdio.h>
int main(void){
    printf("Hello World!");
    printf("Goodbye \a");
    printf("Hi \b");
    printf("Yo\f");
    printf("What? \t");
    printf("pewpew");
    return 0;
}

Not really and I am talking about SQL Server. The temp table (with single #) exists and is visible within the scope it is created (scope-bound). Each time you call your stored procedure it creates a new scope and therefore that temp table exists only in that scope. I believe the temp tables are also visible to stored procedures and udfs that're called within that scope as well. If you however use double pound (##) then they become global within your session and therefore visible to other executing processes as part of the session that the temp table is created in and you will have to think if the possibility of temp table being accessed concurrently is desirable or not.

You could also use the loadtxt command in NumPy. This checks for fewer conditions than genfromtxt, so it may be faster.

import numpy
data = numpy.loadtxt(filename, delimiter="\n")

In your example, because you use CurrentDB to execute your INSERT you've made it harder for yourself. Instead, this will work:

  Dim query As String
  Dim newRow As Long  ' note change of data type
  Dim db As DAO.Database

  query = "INSERT INTO InvoiceNumbers (date) VALUES (" & NOW() & ");"
  Set db = CurrentDB
  db.Execute(query)
  newRow = db.OpenRecordset("SELECT @@IDENTITY")(0)
  Set db = Nothing

I used to do INSERTs by opening an AddOnly recordset and picking up the ID from there, but this here is a lot more efficient. And note that it doesn't require ADO.

For Swift 5

Remove Cell

    let indexPath = [NSIndexPath(row: yourArray-1, section: 0)]
    yourArray.remove(at: buttonTag)
    self.tableView.beginUpdates()

    self.tableView.deleteRows(at: indexPath as [IndexPath] , with: .fade)
    self.tableView.endUpdates()
    self.tableView.reloadData()// Not mendatory, But In my case its requires

Add new cell

    yourArray.append(4)

    tableView.beginUpdates()
    tableView.insertRows(at: [
        (NSIndexPath(row: yourArray.count-1, section: 0) as IndexPath)], with: .automatic)
    tableView.endUpdates()

I believe I have a non-javascript solution! Better late than never, right? After all this is an excellent question and Google is all over it. I didn't want to settle for a javascript fix because I find the slight jitter of things moving around after the page is loaded to be unacceptable.

Features:

• No javascript
• No fixed-layout
• No weighting or percentage-width tricks
• Works with any number of columns
• Simple server-side generation and client-side updating (no calculation necessary)
• Cross-browser compatible

How it works: Inside the table cell place two copies of the content in two different elements within a relatively-positioned container element. The spacer element is statically-positioned and as such will affect the width of the table cells. By allowing the contents of the spacer cell to wrap we can get the "best-fit" width of the table cells that we are looking for. This also allows us to use the absolutely-positioned element to restrict the width of the visible content to that of the relatively-positioned parent.

This answer doesn't help for SQL databases where SharePoint is connected. db_securityadmin is required for the configuration databases. In order to add db_securityadmin, you will need to change the owner of the database to an administrative account. You can use that account just for dbo roles.

In the scenario you would NOT like to use the onChange handler on the input DOM, you can use the onClick property as an alternative. The defaultChecked, the condition may leave a fixed state for v16 IINM.

             target.removeAttribute('checked');
             target.parentNode.style.textDecoration = "";
          } else {
             target.setAttribute('checked', true);
             target.parentNode.style.textDecoration = "line-through";

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Kudos to this answer for showing me the way.

You can set the Property FormBorderStyle to none in the designer, or in code:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

the official docs says it should return false and set E_NOTICE

but since you got error then the error reporting is set to be triggered by E_NOTICE

here is a fix to allow you detect false returned by unserialize

$old_err=error_reporting(); 
error_reporting($old_err & ~E_NOTICE);
$object = unserialize($serialized_data);
error_reporting($old_err);

you might want to consider use base64 encode/decode

$string=base64_encode(serialize($obj));
unserialize(base64_decode($string));

Place this line before the closing script tag,writing from memory:

i think the question is how to call the javascript function on pageload

For those coming to this with similar problems, this request library allows you to make external http requests seemlessly within your php application. Simplified GET, POST, PATCH, DELETE and PUT requests.

A sample request would be as below

use Libraries\Request;

$data = [
  'samplekey' => 'value',
  'otherkey' => 'othervalue'
];

$headers = [
  'Content-Type' => 'application/json',
  'Content-Length' => sizeof($data)
];

$response = Request::post('https://example.com', $data, $headers);
// the $response variable contains response from the request

Documentation for the same can be found in the project's README.md

For me it worked like the code below. I made a difference between RouterModule.forRoot and RouterModule.forChild. Then in the child define the parent path and in the children array the childs.

parent-routing.module.ts

RouterModule.forRoot([
  {
    path: 'parent',  //parent path, define the component that you imported earlier..
    component: ParentComponent,
  }
]),
RouterModule.forChild([
  {
    path: 'parent', //parent path
    children: [
      {
        path: '', 
        redirectTo: '/parent/childs', //full child path
        pathMatch: 'full'
      },
      {
        path: 'childs', 
        component: ParentChildsComponent,
      },
    ]
  }
])

Hope this helps.

I had the same issue when I first tried on node js.
I noticed this issue was happening to me because I had some .js files with same names in different directories, which were in the same main directory.
I created another directory outside the main project folder, and created a .js file.
After that, it ran fine.
ex- app.js

Opening CMD in the location of the already installed request folder and running "pip install requests" worked for me. I am using two different versions of Python.

I think this works because requests is now installed outside my virtual environment. Haven't checked but just thought I'd write this in, in case anyone else is going crazy searching on Google.

You are calling the addToCart method and passing the product id. Now you may use jQuery ajax to pass that data to your server side action method.d

jQuery post is the short version of jQuery ajax.

function addToCart(id)
{
  $.post('@Url.Action("Add","Cart")',{id:id } function(data) {
    //do whatever with the result.
  });
}

If you want more options like success callbacks and error handling, use jQuery ajax,

function addToCart(id)
{
  $.ajax({
  url: '@Url.Action("Add","Cart")',
  data: { id: id },
  success: function(data){
    //call is successfully completed and we got result in data
  },
  error:function (xhr, ajaxOptions, thrownError){
                  //some errror, some show err msg to user and log the error  
                  alert(xhr.responseText);

                }    
  });
}

When making ajax calls, I strongly recommend using the Html helper method such as Url.Action to generate the path to your action methods.

This will work if your code is in a razor view because Url.Action will be executed by razor at server side and that c# expression will be replaced with the correct relative path. But if you are using your jQuery code in your external js file, You may consider the approach mentioned in this answer.

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

I'm pretty sure it's an Adobe standard, bearing in mind the whole PDF standard is theirs to begin with; despite being open now.

My guess would be no for all PDF viewers supporting it, as some definitely will not have a JS engine. I doubt you can rely on full support outside the most recent versions of Acrobat (Reader). So I guess it depends on how you imagine it being used, if mainly via a browser display, then the majority of the market is catered for by Acrobat (Reader) and Chrome's built-in viewer - dare say there is documentation on whether Chrome's PDF viewer supports JS fully.

I'm going to add one suggestion here aimed at Android users. You can do this which avoids having to get any external libraries. Also, all the search/replace characters solutions suggested in some of the answers above are perilous and should be avoided.

Give this a try:

String urlStr = "http://abc.dev.domain.com/0007AC/ads/800x480 15sec h.264.mp4";
URL url = new URL(urlStr);
URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
url = uri.toURL();

You can see that in this particular URL, I need to have those spaces encoded so that I can use it for a request.

This takes advantage of a couple features available to you in Android classes. First, the URL class can break a url into its proper components so there is no need for you to do any string search/replace work. Secondly, this approach takes advantage of the URI class feature of properly escaping components when you construct a URI via components rather than from a single string.

The beauty of this approach is that you can take any valid url string and have it work without needing any special knowledge of it yourself.

I faced the same problem. I found two solutions: (1) Editing the jar file manually:

Open the jar file with WinRar (or similar tools). Go to Meta-info > services , and edit "org.apache.hadoop.fs.FileSystem" by appending:

org.apache.hadoop.fs.LocalFileSystem

(2) Changing the order of my dependencies as follow

<dependencies>
<dependency>
  <groupId>org.apache.hadoop</groupId>
  <artifactId>hadoop-hdfs</artifactId>
  <version>3.2.1</version>
</dependency>

<dependency>
  <groupId>org.apache.hadoop</groupId>
  <artifactId>hadoop-common</artifactId>
  <version>3.2.1</version>
</dependency>

<dependency>
  <groupId>org.apache.hadoop</groupId>
  <artifactId>hadoop-mapreduce-client-core</artifactId>

I found this. Using:

galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

for one of the intents shows the user the option of selecting 'documents' in Android 4, which I found very confusing. Using this instead shows the 'gallery' option:

Intent pickIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

 public class Stack {
     int[] arr;
     int MAX_SIZE;
     int top;

public Stack(int n){
    MAX_SIZE = n;
    arr = new int[MAX_SIZE];
    top=0;
}

    public boolean isEmpty(){
        if(top ==0)
            return true;
      else
        return false;
   }

public boolean push(int ele){

    if(top<MAX_SIZE){
        arr[top] = ele;
        top++;
        return true;
    }
    else{
        System.out.println("Stack is full");
        return false;
    }
}
public void show(){
    for(int element:arr){
        System.out.print(element+" ");
    }
}
public int size(){
    return top;
}
   public int peek(){
        if(!isEmpty()){
            int peekTest = arr[top-1];
            return peekTest;
                    }
   else{
       System.out.println("Stack is empty");
       return 0;
   } 
}
public int pop(){
    if(isEmpty()){
        System.out.println("Stack is Emmpty");
        return 0;
    }
    else{
        int element = arr[--top];
        return element;
    }
}

}

In Swift 3.0:

var value: Int = 10
var string = String(describing: value)

This Status Code 500 is an Internal Server Error. This code indicates that a part of the server (for example, a CGI program) has crashed or encountered a configuration error.

i think the problem does'nt lie on your side, but rather on the side of the Http server. the resources you used to access may have been moved or get corrupted, or its configuration just may have altered or spoiled

The size arguments are in pixels. So, to double your example's marker size the fifth argument to the MarkerImage constructor would be:

new google.maps.Size(42,68)

I find it easiest to let the map API figure out the other arguments, unless I need something other than the bottom/center of the image as the anchor. In your case you could do:

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor,
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);

• Right click the Google Chrome icon and select Properties.
• Copy the value of Target, for example: "C:\Users\zero\AppData\Local\Google\Chrome\Application\chrome.exe".
• Create a shortcut on your Desktop.

• Paste the value into Location of the item, and append --kiosk <your url>:

  "C:\Users\zero\AppData\Local\Google\Chrome\Application\chrome.exe" --kiosk http://www.google.com
  

• Press Apply, then OK.

• To start Chrome at Windows startup, copy this shortcut and paste it into the Startup folder (Start -> Program -> Startup).

In my experience, a "typical" use of eval is for running commands that generate shell commands to set environment variables.

Perhaps you have a system that uses a collection of environment variables, and you have a script or program that determines which ones should be set and their values. Whenever you run a script or program, it runs in a forked process, so anything it does directly to environment variables is lost when it exits. But that script or program can send the export commands to stdout.

Without eval, you would need to redirect stdout to a temp file, source the temp file, and then delete it. With eval, you can just:

eval "$(script-or-program)"

Note the quotes are important. Take this (contrived) example:

# activate.sh
echo 'I got activated!'

# test.py
print("export foo=bar/baz/womp")
print(". activate.sh")

$ eval $(python test.py)
bash: export: `.': not a valid identifier
bash: export: `activate.sh': not a valid identifier
$ eval "$(python test.py)"
I got activated!

just continuing what @Mulki made with his code

public string WebRequestinJson(string url, string postData)
{
    string ret = string.Empty;

    StreamWriter requestWriter;

    var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
    if (webRequest != null)
    {
        webRequest.Method = "POST";
        webRequest.ServicePoint.Expect100Continue = false;
        webRequest.Timeout = 20000;

        webRequest.ContentType = "application/json";
        //POST the data.
        using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }
    }

    HttpWebResponse resp = (HttpWebResponse)webRequest.GetResponse();
    Stream resStream = resp.GetResponseStream();
    StreamReader reader = new StreamReader(resStream);
    ret = reader.ReadToEnd();

    return ret;
}

As of Java 7 (and Android API level 19):

System.lineSeparator()

Documentation: Java Platform SE 7

For older versions of Java, use:

System.getProperty("line.separator");

See https://java.sun.com/docs/books/tutorial/essential/environment/sysprop.html for other properties.

When entering the script's full file spec or its filename on the command line, the shell will use information accessibly by

assoc | grep -i vbs
.vbs=VBSFile

ftype | grep -i vbs
VBSFile=%SystemRoot%\System32\CScript.exe "%1" %*

to decide which program to run for the script. In my case it's cscript.exe, in yours it will be wscript.exe - that explains why your WScript.Echos result in MsgBoxes.

As

cscript /?
Usage: CScript scriptname.extension [option...] [arguments...]

Options:
 //B         Batch mode: Suppresses script errors and prompts from displaying
 //D         Enable Active Debugging
 //E:engine  Use engine for executing script
 //H:CScript Changes the default script host to CScript.exe
 //H:WScript Changes the default script host to WScript.exe (default)
 //I         Interactive mode (default, opposite of //B)
 //Job:xxxx  Execute a WSF job
 //Logo      Display logo (default)
 //Nologo    Prevent logo display: No banner will be shown at execution time
 //S         Save current command line options for this user
 //T:nn      Time out in seconds:  Maximum time a script is permitted to run
 //X         Execute script in debugger
 //U         Use Unicode for redirected I/O from the console

shows, you can use //E and //S to permanently switch your default host to cscript.exe.

If you are so lazy that you don't even want to type the extension, make sure that the PATHEXT environment variable

set | grep -i vbs
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.py;.pyw;.tcl;.PSC1

contains .VBS and there is no Converter.cmd (that converts your harddisk into a washing machine) in your path.

Update wrt comment:

If you 'don't want to specify the full path of my vbscript everytime' you may:

1. put your CONVERTER.VBS in a folder that is included in the PATH environment variable; the shell will then search all pathes - if necessary taking the PATHEXT and the ftype/assoc info into account - for a matching 'executable'.
2. put a CONVERTER.BAT/.CMD into a path directory that contains a line like cscript p:\ath\to\CONVERTER.VBS

In both cases I would type out the extension to avoid (nasty) surprises.

You could try something like this in javascript:
var regex = /[^a-zA-Z]/g;

and have a keyup event.
$("#nameofInputbox").value.replace(regex, "");

The method array.toString() actually calls array.join() which result in a string concatenated by commas. ref

var array = ['a','b','c','d','e','f'];_x000D_
document.write(array.toString()); // "a,b,c,d,e,f"

Also, you can implicitly call Array.toString() by making javascript coerce the Array to an string, like:

//will implicitly call array.toString()
str = ""+array;
str = `${array}`;

Array.prototype.join()

The join() method joins all elements of an array into a string.

Arguments:

It accepts a separator as argument, but the default is already a comma ,

str = arr.join([separator = ','])

Examples:

var array = ['A', 'B', 'C'];
var myVar1 = array.join();      // 'A,B,C'
var myVar2 = array.join(', ');  // 'A, B, C'
var myVar3 = array.join(' + '); // 'A + B + C'
var myVar4 = array.join('');    // 'ABC'

Note:

If any element of the array is undefined or null , it is treated as an empty string.

Browser support:

It is available pretty much everywhere today, since IE 5.5 (1999~2000).

use isset for this purpose

<?php

 $index = 1;
 if(isset($_POST['filename'])) {
     $filename = $_POST['filename'];
     echo $filename;
 }

?>

You can use below link: New line in javascript

  var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   /document.write('<br>');

}

what I do is here:

1. in /etc/apt/sources.list, add:

   deb http://ftp.de.debian.org/debian sid main

Note:the rjava should be latest version

2 run: sudo apt-get update sudo apt-get install r-cran-rjava

Once update the old version of rjava, then can install rhdfs_1.0.8.

locals()["myfunction"]()

or

globals()["myfunction"]()

locals returns a dictionary with a current local symbol table. globals returns a dictionary with global symbol table.

This simple solution worked for me: file-upload.component.html

<div>
  <input type="file" #fileInput placeholder="Upload file..." />
  <button type="button" (click)="upload()">Upload</button>
</div>

And then do the upload in the component directly with XMLHttpRequest.

import { Component, OnInit, ViewChild } from '@angular/core';

@Component({
  selector: 'app-file-upload',
  templateUrl: './file-upload.component.html',
  styleUrls: ['./file-upload.component.css']
})
export class FileUploadComponent implements OnInit {

  @ViewChild('fileInput') fileInput;

  constructor() { }

  ngOnInit() {
  }

  private upload() {
    const fileBrowser = this.fileInput.nativeElement;
    if (fileBrowser.files && fileBrowser.files[0]) {
      const formData = new FormData();
      formData.append('files', fileBrowser.files[0]);
      const xhr = new XMLHttpRequest();
      xhr.open('POST', '/api/Data/UploadFiles', true);
      xhr.onload = function () {
        if (this['status'] === 200) {
            const responseText = this['responseText'];
            const files = JSON.parse(responseText);
            //todo: emit event
        } else {
          //todo: error handling
        }
      };
      xhr.send(formData);
    }
  }

}

If you are using dotnet core, the parameter name must match the from field name. files in this case:

[HttpPost("[action]")]
public async Task<IList<FileDto>> UploadFiles(List<IFormFile> files)
{
  return await _binaryService.UploadFilesAsync(files);
}

This answer is a plagiate of http://blog.teamtreehouse.com/uploading-files-ajax

Edit: After uploading, you have to clear the file-upload so that the user can select a new file. And instead of using XMLHttpRequest, maybe it is better to use fetch:

private addFileInput() {
    const fileInputParentNative = this.fileInputParent.nativeElement;
    const oldFileInput = fileInputParentNative.querySelector('input');
    const newFileInput = document.createElement('input');
    newFileInput.type = 'file';
    newFileInput.multiple = true;
    newFileInput.name = 'fileInput';
    const uploadfiles = this.uploadFiles.bind(this);
    newFileInput.onchange = uploadfiles;
    oldFileInput.parentNode.replaceChild(newFileInput, oldFileInput);
  }

  private uploadFiles() {
    this.onUploadStarted.emit();
    const fileInputParentNative = this.fileInputParent.nativeElement;
    const fileInput = fileInputParentNative.querySelector('input');
    if (fileInput.files && fileInput.files.length > 0) {
      const formData = new FormData();
      for (let i = 0; i < fileInput.files.length; i++) {
        formData.append('files', fileInput.files[i]);
      }

      const onUploaded = this.onUploaded;
      const onError = this.onError;
      const addFileInput = this.addFileInput.bind(this);
      fetch('/api/Data/UploadFiles', {
        credentials: 'include',
        method: 'POST',
        body: formData,
      }).then((response: any) => {
        if (response.status !== 200) {
          const error = `An error occured. Status: ${response.status}`;
          throw new Error(error);
        }
        return response.json();
      }).then(files => {
        onUploaded.emit(files);
        addFileInput();
      }).catch((error) => {
        onError.emit(error);
      });
    }

https://github.com/yonexbat/cran/blob/master/cranangularclient/src/app/file-upload/file-upload.component.ts

Simple code that gives you the difference with multiple items if you want that:

a=[1,2,3,3,4]
b=[2,4]
tmp = copy.deepcopy(a)
for k in b:
    if k in tmp:
        tmp.remove(k)
print(tmp)

Maybe a simple loop for chars to replace:

a = '&#'

to_replace = ['&', '#']

for char in to_replace:
    a = a.replace(char, "\\"+char)

print(a)

  if(condition){

}

Or something like that I would think. To get the effect of the do while loop, simply check for your condition at the end of the group of statements.

You need not specify receiver. You can use adb instead.

adb shell am broadcast -a com.whereismywifeserver.intent.TEST 
--es sms_body "test from adb"

For more arguments such as integer extras, see the documentation.

Both seems to be working same but there is a catch.

r+ :-

• Open the file for Reading and Writing
• Once Opened in the beginning file pointer will point to 0
• Now if you will want to Read then it will start reading from beginning
• if you want to Write then start writing, But the write process will begin from pointer 0. So there would be overwrite of characters, if there is any
• In this case File should be present, either will FileNotFoundError will be raised.

w+ :-

• Open the file for Reading and Writing
• If file exist, File will be opened and all data will be erased,
• If file does not exist, then new file will be created
• In the beginning file pointer will point to 0 (as there is not data)
• Now if you want to write something, then write
• File pointer will be Now pointing to end of file (after write process)
• If you want to read the data now, seek to specific point. (for beginning seek(0))

So, Overall saying both are meant to open the file to read and write but difference is whether we want to erase the data in the beginning and then do read/write or just start as it is.

library is an object, not an array. You push things onto arrays. Unlike PHP, Javascript makes a distinction.

Your code tries to make a string that looks like the source code for a key-value pair, and then "push" it onto the object. That's not even close to how it works.

What you want to do is add a new key-value pair to the object, where the key is the title and the value is another object. That looks like this:

library[title] = {"foregrounds" : foregrounds, "backgrounds" : backgrounds};

"JSON object" is a vague term. You must be careful to distinguish between an actual object in memory in your program, and a fragment of text that is in JSON format.

You have two ways to do that:

METHOD 1. The secure way.

Put the images on /www/htdocs/

<?php
    $www_root = 'http://localhost/images';
    $dir = '/var/www/images';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="', $www_root, '/', $file, '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

METHOD 2. Unsecure but more flexible.

Put the images on any directory (apache must have permission to read the file).

<?php
    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="file_viewer.php?file=', base64_encode($dir . '/' . $file), '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

And create another script to read the image file.

<?php
    $filename = base64_decode($_GET['file']);
    // Check the folder location to avoid exploit
    if (dirname($filename) == '/home/user/Pictures')
        echo file_get_contents($filename);
?>

You could use --where option on mysqldump to produce an output that you are waiting for:

mysqldump -u root -p test t1 --where="1=1 limit 100" > arquivo.sql

At most 100 rows from test.t1 will be dumped from database table.

Tested with: log4j-ap 2.13.2, log4j-core 2.13.2.

1. Keep XML file directly under below folder structure. src/main/java
2. In the POM:

    <build>   
 <resources>       
             <resource>
                <filtering>false</filtering>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>             
            </resource>
 </resources>  
</build>

3. Clean and build.

The problem with your code is :

     String  show[]= {rs4.getString(1)};
     String actuate[]={rs4.getString(2)};

This will create a new array every time your loop (an not append as you might be assuming) and hence in the end you will have only one element per array.

Here is one more way to solve this :

    StringBuilder sids = new StringBuilder ();
    StringBuilder lids = new StringBuilder ();

    while (rs4.next()) {
        sids.append(rs4.getString(1)).append(" ");
        lids.append(rs4.getString(2)).append(" ");
    }

    String show[] = sids.toString().split(" "); 
    String actuate[] = lids.toString().split(" ");

These arrays will have all the required element.

Actually the minimum amount of Angular to be used (as requested in the original question) is just adding a class to the DOM element when show variable is true, and perform the animation/transition via CSS.

So your minimum Angular code is this:

<div class="box-opener" (click)="show = !show">
    Open/close the box
</div>

<div class="box" [class.opened]="show">
    <!-- Content -->
</div>

With this solution, you need to create CSS rules for the transition, something like this:

.box {
    background-color: #FFCC55;
    max-height: 0px;
    overflow-y: hidden;
    transition: ease-in-out 400ms max-height;
}

.box.opened {
    max-height: 500px;
    transition: ease-in-out 600ms max-height;
}

If you have retro-browser-compatibility issues, just remember to add the vendor prefixes in the transitions.

See the example here

To summarize what has been commented in other answers:

//path = @"C:\Temp\Bar\Foo\Test.txt";
Directory.CreateDirectory(Path.GetDirectoryName(path));

Directory.CreateDirectory will create the directories recursively and if the directory already exist it will return without an error.

If there happened to be a file Foo at C:\Temp\Bar\Foo an exception will be thrown.

The stupid simple answer

Connect and Express are web servers for nodejs. Unlike Apache and IIS, they can both use the same modules, referred to as "middleware".

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

Perhaps the shortest possible ways to evaluate an expression into "10" without digits are:

+!+[] + [+[]] // "10"

-~[] + [+[]] // "10"

//========== Explanation ==========\\

+!+[] : +[] Converts to 0. !0 converts to true. +true converts to 1. -~[] = -(-1) which is 1

[+[]] : +[] Converts to 0. [0] is an array with a single element 0.

Then JS evaluates the 1 + [0], thus Number + Array expression. Then the ECMA specification works: + operator converts both operands to a string by calling the toString()/valueOf() functions from the base Object prototype. It operates as an additive function if both operands of an expression are numbers only. The trick is that arrays easily convert their elements into a concatenated string representation.

Some examples:

1 + {} //    "1[object Object]"
1 + [] //    "1"
1 + new Date() //    "1Wed Jun 19 2013 12:13:25 GMT+0400 (Caucasus Standard Time)"

There's a nice exception that two Objects addition results in NaN:

[] + []   //    ""
[1] + [2] //    "12"
{} + {}   //    NaN
{a:1} + {b:2}     //    NaN
[1, {}] + [2, {}] //    "1,[object Object]2,[object Object]"

If you want to use it with reverse() you can do this : request.build_absolute_uri(reverse('view_name', args=(obj.pk, )))

Both of the options you provided are the same. Both of them will still point to the same object in memory and have the same array values. You should treat the state object as immutable as you said, however you need to re-create the array so its pointing to a new object, set the new item, then reset the state. Example:

onChange(event){
    var newArray = this.state.arr.slice();    
    newArray.push("new value");   
    this.setState({arr:newArray})
}

String#toLowerCase

Here are quite a few ways to add dictionaries.

You can use Python3's dictionary unpacking feature.

ndic = {**dic0, **dic1}

Or create a new dict by adding both items.

ndic = dict(dic0.items() + dic1.items())

If your ok to modify dic0

dic0.update(dic1)

If your NOT ok to modify dic0

ndic = dic0.copy()
ndic.update(dic1)

If all the keys in one dict are ensured to be strings (dic1 in this case, of course args can be swapped)

ndic = dict(dic0, **dic1)

In some cases it may be handy to use dict comprehensions (Python 2.7 or newer),
Especially if you want to filter out or transform some keys/values at the same time.

ndic = {k: v for d in (dic0, dic1) for k, v in d.items()}

None of these answers achieved what I was looking for, so I wound up writing something myself. I wanted to pinch-zoom an image on my website using my MacBookPro trackpad. The following code (which requires jQuery) seems to work in Chrome and Edge, at least. Maybe this will be of use to someone else.

function setupImageEnlargement(el)

    // "el" represents the image element, such as the results of document.getElementByd('image-id')
    var img = $(el);
    $(window, 'html', 'body').bind('scroll touchmove mousewheel', function(e)
    {
        //TODO: need to limit this to when the mouse is over the image in question

        //TODO: behavior not the same in Safari and FF, but seems to work in Edge and Chrome

        if (typeof e.originalEvent != 'undefined' && e.originalEvent != null
            && e.originalEvent.wheelDelta != 'undefined' && e.originalEvent.wheelDelta != null)
        {
            e.preventDefault();
            e.stopPropagation();
            console.log(e);
            if (e.originalEvent.wheelDelta > 0)
            {
                // zooming
                var newW = 1.1 * parseFloat(img.width());
                var newH = 1.1 * parseFloat(img.height());
                if (newW < el.naturalWidth && newH < el.naturalHeight)

There is no built-in formula in excel, you have to add a vb script and permanently save it with your MS. Excel's installation as Add-In.

1. press Alt+F11
2. MENU: (Tool Strip) Insert Module
3. copy and paste the below code

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

Add this code before the HttpsURLConnection and it will be done. I got it.

private void trustEveryone() {

I hope this helps you.

In my case, I opened my .csproj file in notepad and removed the following three lines. Worked like a charm:

<Import Project="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />

try: window.document......

var body = window.document.getElementsByTagName("body")[0];

There's a built-in interface that you can use directly for all gestures:
Here is an explanation for a basic level user: There is 2 imports be careful in choosing that both are diferent

Sadly, no. The header and footer are generated by the browser. Only the end-user can change the footer - it might be an idea to give the user a step-by-step for each browser what to do. See for example here for a set of illustrated walk-throughs for windows based browsers.

The only alternative I know of is generating PDFs, with which you have full control over the printed output.

You can change it manually:

private void UpdateConfigFile(string appConfigPath, string key, string value)
{
     var appConfigContent = File.ReadAllText(appConfigPath);
     var searchedString = $"<add key=\"{key}\" value=\"";
     var index = appConfigContent.IndexOf(searchedString) + searchedString.Length;
     var currentValue = appConfigContent.Substring(index, appConfigContent.IndexOf("\"", index) - index);
     var newContent = appConfigContent.Replace($"{searchedString}{currentValue}\"", $"{searchedString}{newValue}\"");
     File.WriteAllText(appConfigPath, newContent);
}

I've written a one linear for this:

[1, 3, 1, 4, 1].reduceRight((x, y) => new Array(y).fill().map(() => JSON.parse(JSON.stringify(x))), 0);

I feel however I can spend more time to make a JSON.parse(JSON.stringify())-free version which is used for cloning here.

Btw, have a look at my another answer here.

I faced the same issue in PostMan and Advance REST Client both. I checked through fiddler and found that my request payload is not converted into JSON format.

I am passing my data in Body as x-www-form-urlencoded

You can fix it by using Content-Type as application/x-www-form-urlencoded in request header.

<span style='color:blue '> your message/text </span>

as of 12.03.2019 FusionTables is no more...

Import the Shapefile into Google FusionTables ( http://www.google.com/fusiontables ) using http://www.shpescape.com/ and from there you can use the data in a number of ways, eg. display it using GoogleMaps.

You can use:

$(formId).serializeArray();

You can use ReactDOMServer to render your component to HTML and then use this on jsPDF.

First do the imports:

import React from "react";
import ReactDOMServer from "react-dom/server";
import jsPDF from 'jspdf';

then:

var doc = new jsPDF();
doc.fromHTML(ReactDOMServer.renderToStaticMarkup(this.render()));
doc.save("myDocument.pdf");

Prefer to use:

renderToStaticMarkup

instead of:

renderToString

As the former include HTML code that react relies on.

I faced the same problem and this discussion helped me I just replace this line

android:maxLines="1"

with this line in xml

android:singleLine="true"

and it works the line txtView.setSelected(true); was also in my activity.

A way to do this without Linq & Lambdas

string source = "a,b, b, c";
string[] items = source.Split(new char[] { ',', ' ' }, StringSplitOptions.RemoveEmptyEntries);

You can use on another class

public ArrayList<Integer> myNumbers = new Foo().myNumbers();

or

Foo myClass = new Foo();
 public ArrayList<Integer> myNumbers = myclass.myNumbers();

The value is null, you have to check why... (in addition to the implementation of the solutions proposed here)

Check the hardware Connections.

My problem was in web.xml file. In one <servlet-mapping> there was an error inside <url-pattern>: I forgot to add / before url.

require(reshape2)

T <- dcast(T, A ~ variable, sum)

I am not certain the exact advantages over aggregate.

You can use this, just think Job is the name of the model to which you are adding index cader_id:

class AddCaderIdToJob < ActiveRecord::Migration[5.2]
  def change
    change_table :jobs do |t|
      t.integer :cader_id
      t.index :cader_id

  if ( page_request.readyState == 1 )
      loading.style.visibility = "visible" ;

  // when loaded successfully
  if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
  {
      document.getElementById(containerid).innerHTML=page_request.responseText ;
      loading.style.visibility = "hidden" ;
  }
}

The first step is figuring out what the error actually is. In order to do this expand your MsBuild output to be diagnostic. This will reveal the actual command executed and hopefully the full error message as well

• Tools -> Options
• Projects and Solutions -> Build and Run
• Change "MsBuild project build output verbosity" to "Diagnostic".

If the file contains only parameter assignments, you can use the following loop in place of sourcing it:

# Instead of source file.txt
while IFS="=" read name value; do
    declare "$name=$value"
done < file.txt

This saves you having to quote anything in the file, and is also more secure, as you don't risk executing arbitrary code from file.txt.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

Try this:

.row > .span3 {
    display: inline-block !important;
    vertical-align: middle !important;
}

Edit:

Fiddle: http://jsfiddle.net/EexYE/

You may need to add Diego's float: none !important; also if span3 is floating and it interferes.

Edit:

Fiddle: http://jsfiddle.net/D8McR/

In response to Alberto: if you fix the height of the row div, then to continue the vertical center alignment you'll need to set the line-height of the row to be the same as the pixel height of the row (ie. both to 300px in your case). If you'll do that you will notice that the child elements inherit the line-height, which is a problem in this case, so you will then need to set your line height for the span3s to whatever it should actually be (1.5 is the example value in the fiddle, or 1.5 x the font-size, which we did not change when we changed the line-height).

raw.github.com/user/repository is no longer there

To link, href to source code in github, you have to use github link to raw source this way:

raw.githubusercontent.com/user/repository/master/file.extension

EXAMPLE

<html>
...
...
<head>    
<script src="https://raw.githubusercontent.com/amiahmadtouseef/tutorialhtmlfive/master/petdecider/script.js"></script>
...
</head>
<body>
...
</html>

When in a window, go to GO ---> ENTER LOCATION... And then copy paste this: /opt/lampp/htdocs

Now you are at the htdocs folder. Then you can add your files there, or in a new folder inside this one (for example "myproyects" folder and inside it your files... and then from a navigator you access it by writting: localhost/myproyects/nameofthefile.php

What I did to find it easily everytime, was right click on "myproyects" folder and "Make link..."... then I moved this link I created to the Desktop and then I didn't have to go anymore to the htdocs, but just enter the folder I created in my Desktop.

Hope it helps!!

To insert just a newline:

sed '1i\\'

One way is to add the item(s) to be deleted to a new list. Then go through and delete those items.

Use FilenameUtils.removeExtension from Apache Commons IO

Example:

You can provide full path name or only the file name.

String myString1 = FilenameUtils.removeExtension("helloworld.exe"); // returns "helloworld"
String myString2 = FilenameUtils.removeExtension("/home/abc/yey.xls"); // returns "yey"

Hope this helps ..

It appears I cannot use an if statement.

Arrow functions either allow to use an expression or a block as their body. Passing an expression

foo => bar

is equivalent to the following block

foo => { return bar; }

However,

if (person.age > 18) person

is not an expression, if is a statement. Hence you would have to use a block, if you wanted to use if in an arrow function:

foo => {  if (person.age > 18) return person; }

While that technically solves the problem, this a confusing use of .filter, because it suggests that you have to return the value that should be contained in the output array. However, the callback passed to .filter should return a Boolean, i.e. true or false, indicating whether the element should be included in the new array or not.

So all you need is

family.filter(person => person.age > 18);

In ES5:

family.filter(function (person) {
  return person.age > 18;
});

For completeness, you can also use:

mystring = mystring.strip()  # the while loop will leave a trailing space, 
                  # so the trailing whitespace must be dealt with
                  # before or after the while loop
while '  ' in mystring:
    mystring = mystring.replace('  ', ' ')

which will work quickly on strings with relatively few spaces (faster than re in these situations).

In any scenario, Alex Martelli's split/join solution performs at least as quickly (usually significantly more so).

In your example, using the default values of timeit.Timer.repeat(), I get the following times:

str.replace: [1.4317800167340238, 1.4174888149192384, 1.4163512401715934]
re.sub:      [3.741931446594549,  3.8389395858970374, 3.973777672860706]
split/join:  [0.6530919432498195, 0.6252146571700905, 0.6346594329726258]

EDIT:

Just came across this post which provides a rather long comparison of the speeds of these methods.

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

Carry Flag is a flag set when:

a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.

b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.

Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)

Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.

You can read more about flags on wikipedia

Using Java:

WebElement webElement = driver.findElement(By.xpath(""));//You can use xpath, ID or name whatever you like
webElement.sendKeys(Keys.TAB);
webElement.sendKeys(Keys.ENTER);

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

For calling javascript in your action link you simply need to write actionlink like this:

@Html.ActionLink("Delete", "Your-Action", new { id = item.id },
                 new { onclick="return confirm('Are you sure?');"})

Don't get confused between route values and the html attributes.

I was looking to do the same thing, but to preserve the list as a just an array of strings so I wrote a new code, which from what I've been reading may not be the most efficient but worked for what i needed to do:

combineListsAsOne <-function(list1, list2){
  n <- c()
  for(x in list1){
    n<-c(n, x)
  }
  for(y in list2){
    n<-c(n, y)
  }
  return(n)
}

It just creates a new list and adds items from two supplied lists to create one.

If you're set on using scanf, you can do something like the following:

int val;
char follow;  
int read = scanf( "%d%c", &val, &follow );

if ( read == 2 )
{
  if ( isspace( follow ) )
  {
    // input is an integer followed by whitespace, accept
  }
  else
  {
    // input is an integer followed by non-whitespace, reject
  }
}
else if ( read == 1 )
{
  // input is an integer followed by EOF, accept
}
else
{
  // input is not an integer, reject
}

Without the need to install the grep variant pcregrep, you can do multiline search with grep.

$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c

Explanation:

-P activate perl-regexp for grep (a powerful extension of regular expressions)

-z suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.

-o print only matching. Because we're using -z, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.

In regexp:

(?s) activate PCRE_DOTALL, which means that . finds any character or newline

\N find anything except newline, even with PCRE_DOTALL activated

.*? find . in non-greedy mode, that is, stops as soon as possible.

^ find start of line

\1 backreference to the first group (\s*). This is a try to find the same indentation of method.

As you can imagine, this search prints the main method in a C (*.c) source file.

Here's a useful little function, which makes using/creating iOS folders a little easier.

You pass it the name of a subfolder, it'll return the full path back to you, and make sure the directory exists.

(Personally, I stick this static function in my AppDelete class, but perhaps this isn't the smartest place to put it.)

Here's how you would call it, to get the "full path" of a MySavedImages subdirectory:

NSString* fullPath = [AppDelegate getFullPath:@"MySavedImages"];

And here's the full function:

+(NSString*)getFullPath:(NSString*)folderName
{
    //  Check whether a subdirectory exists in our sandboxed Documents directory.
    //  Returns the full path of the directory.
    //
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    if (paths.count < 1)
        return nil;

    NSString *rootFolder = [paths firstObject];
    NSString* fullFolderPath = [rootFolder stringByAppendingPathComponent:folderName];

    BOOL isDirectory;
    NSFileManager* manager = [NSFileManager defaultManager];

    if (![manager fileExistsAtPath:fullFolderPath isDirectory:&isDirectory] || !isDirectory) {
        NSError *error = nil;
        NSDictionary *attr = [NSDictionary dictionaryWithObject:NSFileProtectionComplete
                                                         forKey:NSFileProtectionKey];
        [manager createDirectoryAtPath:fullFolderPath
           withIntermediateDirectories:YES
                            attributes:attr
                                 error:&error];
        if (error) {
            NSLog(@"Error creating directory path: %@", [error localizedDescription]);
            return nil;
        }
    }
    return fullFolderPath;
}

Using this little function, it's easy to create a directory in your app's Documents directory (if it doesn't already exist), and to write a file into it.

Here's how I would create the directory, and write the contents of one of my image files into it:

//  Let's create a "MySavedImages" subdirectory (if it doesn't already exist)
NSString* fullPath = [AppDelegate getFullPath:@"MySavedImages"];

//  As an example, let's load the data in one of my images files
NSString* imageFilename = @"icnCross.png";

UIImage* image = [UIImage imageNamed:imageFilename];
NSData *imageData = UIImagePNGRepresentation(image);

//  Obtain the full path+filename where we can write this .png to, in our new MySavedImages directory
NSString* imageFilePathname = [fullPath stringByAppendingPathComponent:imageFilename];

//  Write the data
[imageData writeToFile:imageFilePathname atomically:YES];

Hope this helps !

For me, Join() behavior was always confusing because I was trying to remember who will wait for whom. Don't try to remember it that way.

Underneath, it is pure wait() and notify() mechanism.

We all know that, when we call wait() on any object(t1), calling object(main) is sent to waiting room(Blocked state).

Here, main thread is calling join() which is wait() under the covers. So main thread will wait until it is notified. Notification is given by t1 when it finishes it's run(thread completion).

After receiving the notification, main comes out of waiting room and proceeds it's execution.

If you want to do this via the designer you can do it by following the instructions here "Save changes is not permitted" when changing an existing column to be nullable

Almost all Magento Models have a corresponding Collection object that can be used to fetch multiple instances of a Model.

To instantiate a Product collection, do the following

$collection = Mage::getModel('catalog/product')->getCollection();

Products are a Magento EAV style Model, so you'll need to add on any additional attributes that you want to return.

$collection = Mage::getModel('catalog/product')->getCollection();

//fetch name and orig_price into data
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

There's multiple syntaxes for setting filters on collections. I always use the verbose one below, but you might want to inspect the Magento source for additional ways the filtering methods can be used.

The following shows how to filter by a range of values (greater than AND less than)

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

//filter for products whose orig_price is greater than (gt) 100
$collection->addFieldToFilter(array(
    array('attribute'=>'orig_price','gt'=>'100'),
)); 

//AND filter for products whose orig_price is less than (lt) 130
$collection->addFieldToFilter(array(
    array('attribute'=>'orig_price','lt'=>'130'),
));

While this will filter by a name that equals one thing OR another.

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

//filter for products who name is equal (eq) to Widget A, or equal (eq) to Widget B
$collection->addFieldToFilter(array(
    array('attribute'=>'name','eq'=>'Widget A'),
    array('attribute'=>'name','eq'=>'Widget B'),        
));

A full list of the supported short conditionals (eq,lt, etc.) can be found in the _getConditionSql method in lib/Varien/Data/Collection/Db.php

Finally, all Magento collections may be iterated over (the base collection class implements on of the the iterator interfaces). This is how you'll grab your products once filters are set.

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

//filter for products who name is equal (eq) to Widget A, or equal (eq) to Widget B
$collection->addFieldToFilter(array(
    array('attribute'=>'name','eq'=>'Widget A'),
    array('attribute'=>'name','eq'=>'Widget B'),        
));

foreach ($collection as $product) {
    //var_dump($product);
    var_dump($product->getData());
}

There are more complex scenarios where this doesn't work. What if you want to select an element with class A that doesn't contain elements with class B. You end up needing something more like:

If parent element does not contain certain child element; jQuery

                bodies[a].a[b] = 0;
            }
            bodies[a].mass = 0;
            bodies[a].radius = 1.0;
     }

    return 0;
}

this works fine. your question was not very clear by the way, so match the layout of your source code with the above.

A more cleaner and dynamic way without hardcoding any pixel values in the code.

I wanted to position a dialog (which I inflate on the fly) exactly below a clicked button.

and solved it this way :

    // get the yoffset of the position where your View has to be placed 
    final int yoffset = < calculate the position of the view >

    // position using top margin
    if(myView.getLayoutParams() instanceof MarginLayoutParams) {
        ((MarginLayoutParams) myView.getLayoutParams()).topMargin = yOffset;
    }

However you have to make sure the parent layout of myView is an instance of RelativeLayout.

more complete code :

    // identify the button
    final Button clickedButton = <... code to find the button here ...>

    // inflate the dialog - the following style preserves xml layout params
    final View floatingDialog = 
        this.getLayoutInflater().inflate(R.layout.floating_dialog,
            this.floatingDialogContainer, false);

    this.floatingDialogContainer.addView(floatingDialog);

    // get the buttons position
    final int[] buttonPos = new int[2];
    clickedButton.getLocationOnScreen(buttonPos);        
    final int yOffset =  buttonPos[1] + clickedButton.getHeight();

    // position using top margin
    if(floatingDialog.getLayoutParams() instanceof MarginLayoutParams) {
        ((MarginLayoutParams) floatingDialog.getLayoutParams()).topMargin = yOffset;
    }

This way you can still expect the target view to adjust to any layout parameters set using layout XML files, instead of hardcoding those pixels/dps in your Java code.

each passes into your function index and element. Check index against the length of the set and you're good to go:

var set = $('.requiredText');
var length = set.length;
set.each(function(index, element) {
      thisVal = $(this).val();
      if(parseInt(thisVal) !== 0) {
          console.log('Valid Field: ' + thisVal);
          if (index === (length - 1)) {
              console.log('Last field, submit form here');
          }
      }
});
