Programs & Examples On #Inline xml

Right click in the query pane, select Query Options... and in the Execution->General section (the default when you first open it) there is an Execution time-out setting.

One (quick & dirty) way to resize images it to use HTML & specify the new size in the image element. This even works for animated images with transparency.

I actually have a similar problem. I have a page with multiple radio buttons; each button will set the title and description meta tags of the page, via JavaScript upon change.

For example, if users select the first button, the meta tags will say:

<meta name="title" content="First Title">
<meta name="description" content="First Description">

If the user select the second button, this changes the meta tags to:

<meta name="title" content="Second Title">
<meta name="description" content="Second Description">

... and so on. I have confirmed that the code is working fine via Firebug (i.e. I can see that those two tags were properly changed).

Apparently, Facebook Share only pulls in the title and description meta tags that are available upon page load. The changes to those two tags post page load are completely ignored.

Does anybody have any ideas on how to solve this? That is, to force Facebook to get the latest values that are change after the page loads.

Enclose <img> in <a> tag.

<a href="http://www.google.com.pk"><img src="smiley.gif"></a>

it will open link on same tab, and if you want to open link on new tab then use target="_blank"

<a href="http://www.google.com.pk" target="_blank"><img src="smiley.gif"></a>

Check this, this would be the easiest way to do that,

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
      [self.view endEditing:YES];// this will do the trick
}

Or

This library will handle including scrollbar auto scrolling, tap space to hide the keyboard, etc...

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

I think that in this question is missing one important information.

How many records will you insert?

1. If from 1 to cca. 10.000 then you should use SQL statement (Like they said it is easy to understand and it is easy to write).
2. If from cca. 10.000 to cca. 100.000 then you should use cursor, but you should add logic to commit on every 10.000 records.
3. If from cca. 100.000 to millions then you should use bulk collect for better performance.

(1)

   ArrayList<Object> list = new ArrayList <>();`     
   list.add("ddd");
   list.add(2);
   list.add(11122.33);    
   System.out.println(list);

(2)

 ArrayList arraylist = new ArrayList();
 arraylist.add(5);        
 arraylist.add("saman");     
 arraylist.add(4.3);        
 System.out.println(arraylist);

Here's a move that I'm using to set the color dynamically, it defaults to primary theme if the variable is undefined.

in your component define your color

  /**Sets the button colors - Defaults to primary them color */
  @Input('buttonsColor') _buttonsColor: string

in your style (sass here) - this forces the icon to use the color of it's container

.mat-custom{
  .mat-icon, .mat-icon-button{
     color:inherit !important;
  }  
}

in your html surround your button with a div

        <div [class.mat-custom]="!!_buttonsColor" [style.color]="_buttonsColor"> 
            <button mat-icon-button (click)="doSomething()">
                <mat-icon [svgIcon]="'refresh'" color="primary"></mat-icon>
            </button>
        </div>

There is a quirk with this that might be relevant for some people... From the PHP docs comments.

If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/"feature" on "Unix-like systems" that causes libcurl to timeout immediately if the value is < 1000 ms with the error "cURL Error (28): Timeout was reached". The explanation for this behavior is:

"If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second."

What this means to PHP developers is "You can't use this function without testing it first, because you can't tell if libcurl is using the standard system name resolver (but you can be pretty sure it is)"

The problem is that on (Li|U)nix, when libcurl uses the standard name resolver, a SIGALRM is raised during name resolution which libcurl thinks is the timeout alarm.

The solution is to disable signals using CURLOPT_NOSIGNAL. Here's an example script that requests itself causing a 10-second delay so you can test timeouts:

if (!isset($_GET['foo'])) {
    // Client
    $ch = curl_init('http://localhost/test/test_timeout.php?foo=bar');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
    $data = curl_exec($ch);
    $curl_errno = curl_errno($ch);
    $curl_error = curl_error($ch);
    curl_close($ch);

    if ($curl_errno > 0) {
        echo "cURL Error ($curl_errno): $curl_error\n";
    } else {
        echo "Data received: $data\n";
    }
} else {
    // Server
    sleep(10);
    echo "Done.";
}

From http://www.php.net/manual/en/function.curl-setopt.php#104597

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

you can utilize useCallback hook to do this.

function Parent() {
  const [name, setName] = useState("");
  const getChildChange = useCallback( (updatedName) => {
    setName(updatedName);
  }, []);

  return <div> {name} :
    <Child getChildChange={getChildChange} ></Child>
  </div>
}

function Child(props) {
  const [name, setName] = useState("");

  function handleChange(ele) {
    setName(ele.target.value);
    props.getChildChange(ele.target.value);
  }

  function collectState() {
    return name;
  }

  return (<div>
    <input onChange={handleChange} value={name}></input>
  </div>);
}

As listed on the other answers, there are many reasons you can find to avoid this. It all boils down to one reason that makes the rest moot. The System() function is inherently insecure/untrusted, and should not be introduced into a program unless necessary.

For a student assignment, this condition was never met, and for this reason I would fail an assignment without even running the program if a call to this method was present. (This was made clear from the start.)

You can build it manually:

var m = new Date();
var dateString = m.getUTCFullYear() +"/"+ (m.getUTCMonth()+1) +"/"+ m.getUTCDate() + " " + m.getUTCHours() + ":" + m.getUTCMinutes() + ":" + m.getUTCSeconds();

and to force two digits on the values that require it, you can use something like this:

("0000" + 5).slice(-2)

Which would look like this:

var m = new Date();_x000D_
var dateString =_x000D_
    m.getUTCFullYear() + "/" +_x000D_
    ("0" + (m.getUTCMonth()+1)).slice(-2) + "/" +_x000D_
    ("0" + m.getUTCDate()).slice(-2) + " " +_x000D_
    ("0" + m.getUTCHours()).slice(-2) + ":" +_x000D_
    ("0" + m.getUTCMinutes()).slice(-2) + ":" +_x000D_
    ("0" + m.getUTCSeconds()).slice(-2);_x000D_
_x000D_
console.log(dateString);

EDIT: look at this answer. Using np.cumsum is much faster than np.convolve

A quick and dirty way to smooth data I use, based on a moving average box (by convolution):

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.8

def smooth(y, box_pts):
    box = np.ones(box_pts)/box_pts
    y_smooth = np.convolve(y, box, mode='same')
    return y_smooth

plot(x, y,'o')
plot(x, smooth(y,3), 'r-', lw=2)
plot(x, smooth(y,19), 'g-', lw=2)

To remove the .html extension from your urls, you can use the following code in root/htaccess :

RewriteEngine on


RewriteCond %{THE_REQUEST} /([^.]+)\.html [NC]
RewriteRule ^ /%1 [NC,L,R]

RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^ %{REQUEST_URI}.html [NC,L]

NOTE: If you want to remove any other extension, for example to remove the .php extension, just replace the html everywhere with php in the code above.

You can use

var modal_template_html = $.trim($('#modal_template').html());
var template = $(modal_template_html);

There's another very simple answer which can work for some simple graphs.

Just add a call to guide_legend() into your graph.

ggplot(...) + ... + guide_legend(title="my awesome title")

As shown in the very nice ggplot docs.

If that doesn't work, you can more precisely set your guide parameters with a call to guides:

ggplot(...) + ... + guides(fill=guide_legend("my awesome title"))

You can also vary the shape/color/size by specifying these parameters for your call to guides as well.

Just to add onto the already great answers, you might want to add multiple labels in your project so doing all of this (setting size, style etc) will be a pain. To solve this, you can create a separate UILabel class.

  import UIKit

  class MyLabel: UILabel {

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        initializeLabel()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        initializeLabel()
    }

    func initializeLabel() {

        self.textAlignment = .left
        self.font = UIFont(name: "Halvetica", size: 17)
        self.textColor = UIColor.white

    }

}

To use it, do the following

import UIKit

class ViewController: UIViewController {

     var myLabel: MyLabel()

     override func viewDidLoad() {
          super.viewDidLoad()

          myLabel = MyLabel(frame: CGRect(x: self.view.frame.size.width / 2, y: self.view.frame.size.height / 2, width: 100, height: 20))
          self.view.addSubView(myLabel)
     }


}

Command ? alt ? shift T : reveal the current edited file in the project tree.

You can use {php} tags

Method 1 (won't work in Smarty 3.1 or later):

{php}

$var =
$this->get_template_vars('var');
var_dump($var);

{/php}

Method 2:

{$var|@print_r}

Method 3:

{$var|@var_dump}

There are a few more differences regarding the structure you could mention.

1. Both DLL and EXE share the same file structure - Portable Executable, or PE. To differentiate between the two, one can look in the Characteristics member of IMAGE_FILE_HEADER inside IMAGE_NT_HEADERS. For a DLL, it has the IMAGE_FILE_DLL (0x2000) flag turned on. For a EXE it's the IMAGE_FILE_EXECUTABLE_IMAGE (0x2) flag.
2. PE files consist of some headers and a number of sections. There's usually a section for code, a section for data, a section listing imported functions and a section for resources. Some sections may contain more than one thing. The header also describes a list of data directories that are located in the sections. Those data directories are what enables Windows to find what it needs in the PE. But one type of data directory that an EXE will never have (unless you're building a frankenstein EXE) is the export directory. This is where DLL files have a list of functions they export and can be used by other EXE or DLL files. On the other side, each DLL and EXE has an import directory where it lists the functions and DLL files it requires to run.
3. Also in the PE headers (IMAGE_OPTIONAL_HEADER) is the ImageBase member. It specifies the virtual address at which the PE assumes it will be loaded. If it is loaded at another address, some pointers could point to the wrong memory. As EXE files are amongst the first to be loaded into their new address space, the Windows loader can assure a constant load address and that's usually 0x00400000. That luxury doesn't exist for a DLL. Two DLL files loaded into the same process can request the same address. This is why a DLL has another data directory called Base Relocation Directory that usually resides in its own section - .reloc. This directory contains a list of places in the DLL that need to be rebased/patched so they'll point to the right memory. Most EXE files don't have this directory, but some old compilers do generate them.

Below code works absolutely fine to me and working. This code will read RSA private and public key though java code. You can refer to http://snipplr.com/view/18368/

   import java.io.DataInputStream;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.IOException;
    import java.security.KeyFactory;
    import java.security.NoSuchAlgorithmException;
    import java.security.interfaces.RSAPrivateKey;
    import java.security.interfaces.RSAPublicKey;
    import java.security.spec.InvalidKeySpecException;
    import java.security.spec.PKCS8EncodedKeySpec;
    import java.security.spec.X509EncodedKeySpec;

    public class Demo {

        public static final String PRIVATE_KEY="/home/user/private.der";
        public static final String PUBLIC_KEY="/home/user/public.der";

        public static void main(String[] args) throws IOException, NoSuchAlgorithmException, InvalidKeySpecException {
            //get the private key
            File file = new File(PRIVATE_KEY);
            FileInputStream fis = new FileInputStream(file);
            DataInputStream dis = new DataInputStream(fis);

            byte[] keyBytes = new byte[(int) file.length()];
            dis.readFully(keyBytes);
            dis.close();

            PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec(keyBytes);
            KeyFactory kf = KeyFactory.getInstance("RSA");
            RSAPrivateKey privKey = (RSAPrivateKey) kf.generatePrivate(spec);
            System.out.println("Exponent :" + privKey.getPrivateExponent());
            System.out.println("Modulus" + privKey.getModulus());

            //get the public key
            File file1 = new File(PUBLIC_KEY);
            FileInputStream fis1 = new FileInputStream(file1);
            DataInputStream dis1 = new DataInputStream(fis1);
            byte[] keyBytes1 = new byte[(int) file1.length()];
            dis1.readFully(keyBytes1);
            dis1.close();

            X509EncodedKeySpec spec1 = new X509EncodedKeySpec(keyBytes1);
            KeyFactory kf1 = KeyFactory.getInstance("RSA");
            RSAPublicKey pubKey = (RSAPublicKey) kf1.generatePublic(spec1);

            System.out.println("Exponent :" + pubKey.getPublicExponent());
            System.out.println("Modulus" + pubKey.getModulus());
        }
    }

if you have FK constraints and you don't want to remove the constraint from the table. use "index" instead of primary. then you will be able to alter it's type to auto increment

You can use the overloaded < or > operators.

For example:

DateTime d1 = new DateTime(2008, 1, 1);
DateTime d2 = new DateTime(2008, 1, 2);
if (d1 < d2) { ...

The built-in getopts command is still, AFAIK, limited to single-character options only.

There is (or used to be) an external program getopt that would reorganize a set of options such that it was easier to parse. You could adapt that design to handle long options too. Example usage:

aflag=no
bflag=no
flist=""
set -- $(getopt abf: "$@")
while [ $# -gt 0 ]
do
    case "$1" in
    (-a) aflag=yes;;
    (-b) bflag=yes;;
    (-f) flist="$flist $2"; shift;;
    (--) shift; break;;
    (-*) echo "$0: error - unrecognized option $1" 1>&2; exit 1;;
    (*)  break;;
    esac
    shift
done

# Process remaining non-option arguments
...

You could use a similar scheme with a getoptlong command.

Note that the fundamental weakness with the external getopt program is the difficulty of handling arguments with spaces in them, and in preserving those spaces accurately. This is why the built-in getopts is superior, albeit limited by the fact it only handles single-letter options.

Try this, you can create an extension method like this:

    public static string ContentToString(this HttpContent httpContent)
    {
        var readAsStringAsync = httpContent.ReadAsStringAsync();
        return readAsStringAsync.Result;
    }

and then, simple call the extension method:

txtBlock.Text = response.Content.ContentToString();

I hope this help you ;-)

I had a number of projects in the solution and the web project (problem giving this error) was not set as the StartUp project. I set this web project as the StartUp project, and clicked on the menu item "Debug"->"Start Debugging" and it worked. I stopped debugging and then tried it again and now it’s back working. Weird.

Lodash has a simple Dictionary implementation and has good TypeScript support

Install Lodash:

npm install lodash @types/lodash --save

Import and usage:

import { Dictionary } from "lodash";
let properties : Dictionary<string> = {
    "key": "value"        
}
console.log(properties["key"])

The second thing to learn (one would argue that this should be the first) is the command line interface of your OS and compiler/linker flags and switches.

I am not sure, but might be what you want:

var c = 0;
function setBgPosition()
{
    var numbers = [0, -120, -240, -360, -480, -600, -720];
    function run()
    {
        Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
        if (c<=numbers.length)
        {
            setTimeout(run, 200);
        }
        else
        {
            Ext.get('common-spinner').setStyle('background-position', numbers[0] + 'px 0px');
        }
    }
    setTimeout(run, 200);
}
setBgPosition();

1. Yes, it's allowed.
2. You use the function as you would any other: anotherfunc(*extraArgs)

An IntPtr is a value type that is primarily used to hold memory addresses or handles. A pointer is a memory address. A pointer can be typed (e.g. int*) or untyped (e.g. void*). A Windows handle is a value that is usually the same size (or smaller) than a memory address and represents a system resource (like a file or window).

check $xml->entry[$i] exists and is an object before trying to get a property of it

 if(isset($xml->entry[$i]) && is_object($xml->entry[$i])){
   $source = $xml->entry[$i]->source;          
   $s[$source] += 1;
 }

or $source might not be a legal array offset but an array, object, resource or possibly null

getJSON will evaluate the data to JSON for you, as long as the correct content-type is used. Make sure that the server is returning the data as application/json.

I think you can almost do exactly what you thought would be ideal, using the statsmodels package which was one of pandas' optional dependencies before pandas' version 0.20.0 (it was used for a few things in pandas.stats.)

Distinct the Note class by Author

var DistinctItems = Note.GroupBy(x => x.Author).Select(y => y.First());

foreach(var item in DistinctItems)
{
    //Add to other List
}

NOTE: Programs compiled with high-optimization levels (-O3, -O4) cannot generate many debugging symbols for optimized variables, in-lined functions and unrolled loops, regardless of the symbols being embedded (-g) or extracted (objcopy) into a '.debug' file.

Alternate approaches are

1. Embed the versioning (VCS, git, svn) data into the program, for compiler optimized executables (-O3, -O4).
2. Build a 2nd non-optimized version of the executable.

The first option provides a means to rebuild the production code with full debugging and symbols at a later date. Being able to re-build the original production code with no optimizations is a tremendous help for debugging. (NOTE: This assumes testing was done with the optimized version of the program).

Your build system can create a .c file loaded with the compile date, commit, and other VCS details. Here is a 'make + git' example:

program: program.o version.o 

program.o: program.cpp program.h

After the program is compiled you can locate the original 'commit' for your code by using the command: strings -a my_program | grep VCS

VCS: PROGRAM_NAME=my_program
VCS: Commit=190aa9cace3b12e2b58b692f068d4f5cf22b0145
VCS: BRANCH=refs/heads/PRJ123_feature_desc
VCS: AUTHOR=Joe Developer  [email protected]
VCS: COMMIT_DATE=2013-12-19

All that is left is to check-out the original code, re-compile without optimizations, and start debugging.

ruby 1.8.7 way is the following:

array.inject(0, &:+) 

I usually use XmlDocument for this. The interface is pretty straight forward:

var doc = new XmlDocument();
doc.LoadXml(xmlString);

You can access nodes similar to a dictionary:

var tasks = doc["Tasks"];

and loop over all children of a node.

You can always change a date on your computer, make a commit, then change the date back and push.

Joseph forgot to add the value in his example with withDefault. Here is the code I ended up using:

Map map = [:].withDefault { key -> return [] }
listOfObjects.each { map.get(it.myKey).add(it.myValue) }

The consequence of this is that you may need a rather insane-looking query, e. g.,

SELECT [dbo].[tblTimeSheetExportFiles].[lngRecordID]            AS lngRecordID
          ,[dbo].[tblTimeSheetExportFiles].[vcrSourceWorkbookName]  AS vcrSourceWorkbookName

      LEFT JOIN   [dbo].[tblTimeRecords]
              ON  [dbo].[tblTimeSheetExportFiles].[lngRecordID] = [dbo].[tblTimeRecords].[lngTimeSheetExportFile]
        GROUP BY  [dbo].[tblTimeSheetExportFiles].[lngRecordID]

Since the primary table is a summary table, its primary key handles the only grouping or ordering that is truly necessary. Hence, the GROUP BY clause exists solely to satisfy the query parser.

The default shortcut key is Ctrl-Alt-C.

Just adding to the answers already given, the solution using the string "nunique" seems much faster, tested here on ~21M rows dataframe, then grouped to ~2M

%time _=g.agg({"id": lambda x: x.nunique()})
CPU times: user 3min 3s, sys: 2.94 s, total: 3min 6s
Wall time: 3min 20s

%time _=g.agg({"id": pd.Series.nunique})
CPU times: user 3min 2s, sys: 2.44 s, total: 3min 4s
Wall time: 3min 18s

%time _=g.agg({"id": "nunique"})
CPU times: user 14 s, sys: 4.76 s, total: 18.8 s
Wall time: 24.4 s

I personally used the approach of "if it makes sense for the user to bookmark a URLwhich includes these parameters then use PathParam".

For instance, if the URL for a user profile includes some profile id parameter, since this can be bookmarked by the user and/or emailed around, I would include that profile id as a path parameter. Also, another considerent to this is that the page denoted by the URL which includes the path param doesn't change -- the user will set up his/her profile, save it, and then unlikely to change that much from there on; this means webcrawlers/search engines/browsers/etc can cache this page nicely based on the path.

If a parameter passed in the URL is likely to change the page layout/content then I'd use that as a queryparam. For instance, if the profile URL supports a parameter which specifies whether to show the user email or not, I would consider that to be a query param. (I know, arguably, you could say that the &noemail=1 or whatever parameter it is can be used as a path param and generates 2 separate pages -- one with the email on it, one without it -- but logically that's not the case: it is still the same page with or without certain attributes shown.

Hope this helps -- I appreciate the explanation might be a bit fuzzy :)

2020 Solution - CSS only - No Javascript

Use media hover with media pointer will help you guys resolve this issue. Tested on chrome Web and android mobile. I known this old question but I didn't find any solution like this.

@media (hover: hover) and (pointer: fine) {
  a:hover { color: red; }
}

<a href="#" >Some Link</a>

>>> print "%r, %r" % (True, False)
True, False

This is not specific to boolean values - %r calls the __repr__ method on the argument. %s (for str) should also work.

Simple way is to reset the index of the DataFrame prior to filtering:

df_reset = df.reset_index()
df_reset[df_reset['BoolCol']].index.tolist()

Bit hacky, but it's quick!

 def hi():
     bye = 5
     return bye  

print hi()

When importing an existing Gradle project (one with a build.gradle) into IntelliJ IDEA, when presented with the following screen, select Import from external model -> Gradle.

Optionally, select Auto Import on the next screen to automatically import new dependencies.

There is no verifyTextPresent in Selenium 2 webdriver, so you've to check for the text within the page source. See some practical examples below.

Python

In Python driver you can write the following function:

def is_text_present(self, text):
    return str(text) in self.driver.page_source

then use it as:

try: self.is_text_present("Some text.")
except AssertionError as e: self.verificationErrors.append(str(e))

To use regular expression, try:

def is_regex_text_present(self, text = "(?i)Example|Lorem|ipsum"):
    self.assertRegex(self.driver.page_source, text)
    return True

See: FooTest.py file for full example.

Or check below few other alternatives:

self.assertRegexpMatches(self.driver.find_element_by_xpath("html/body/div[1]/div[2]/div/div[1]/label").text, r"^[\s\S]*Weather[\s\S]*$")
assert "Weather" in self.driver.find_element_by_css_selector("div.classname1.classname2>div.clearfix>label").text

^{Source: Another way to check (assert) if text exists using Selenium Python}

Java

In Java the following function:

public void verifyTextPresent(String value)
{
  driver.PageSource.Contains(value);
}

and the usage would be:

try
{
  Assert.IsTrue(verifyTextPresent("Selenium Wiki"));
  Console.WriteLine("Selenium Wiki test is present on the home page");
}
catch (Exception)
{
  Console.WriteLine("Selenium Wiki test is not present on the home page");
}

^{Source: Using verifyTextPresent in Selenium 2 Webdriver}

Behat

For Behat, you can use Mink extension. It has the following methods defined in MinkContext.php:

/**
 * Checks, that page doesn't contain text matching specified pattern
 * Example: Then I should see text matching "Bruce Wayne, the vigilante"
 * Example: And I should not see "Bruce Wayne, the vigilante"
 *
 * @Then /^(?:|I )should not see text matching (?P<pattern>"(?:[^"]|\\")*")$/
 */
public function assertPageNotMatchesText($pattern)
{
    $this->assertSession()->pageTextNotMatches($this->fixStepArgument($pattern));
}

/**
 * Checks, that HTML response contains specified string
 * Example: Then the response should contain "Batman is the hero Gotham deserves."
 * Example: And the response should contain "Batman is the hero Gotham deserves."
 *
 * @Then /^the response should contain "(?P<text>(?:[^"]|\\")*)"$/
 */
public function assertResponseContains($text)
{
    $this->assertSession()->responseContains($this->fixStepArgument($text));
}

If all you want is to print from Monday onwards, you can use list's index method to find the position where "Monday" is in the list, and iterate from there as explained in other posts. Using list.index saves you hard-coding the index for "Monday", which is a potential source of error:

days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
for d in days[days.index('Monday'):] :
   print d

The best and probably only solution is probably IE tester that could be found at ietester[dot]com It uses the IEengines for all IE 6, 7 and 8! And I have not found any discrepancies yet!

Alternatively, you can use requests.Session and observe cookies before and after a request:

>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())
{}
>>> response = session.get('http://google.com')
>>> print(session.cookies.get_dict())
{'PREF': 'ID=5514c728c9215a9a:FF=0:TM=1406958091:LM=1406958091:S=KfAG0U9jYhrB0XNf', 'NID': '67=TVMYiq2wLMNvJi5SiaONeIQVNqxSc2RAwVrCnuYgTQYAHIZAGESHHPL0xsyM9EMpluLDQgaj3db_V37NjvshV-eoQdA8u43M8UwHMqZdL-S2gjho8j0-Fe1XuH5wYr9v'}

One interesting fact about the obj directory: If you have publishing set up in a web project, the files that will be published are staged to obj\Release\Package\PackageTmp. If you want to publish the files yourself rather than use the integrated VS feature, you can grab the files that you actually need to deploy here, rather than pick through all the digital debris in the bin directory.

No, because technically, the array only stores the reference to the strings. The strings themselves are allocated in a different location. For a thousand items, I would say a list would be better, it is slower, but it offers more flexibility and it's easier to use, especially if you are going to resize them.

hope this is working. make random number between range for arc4random_uniform()?

var randomNumber = Int(arc4random_uniform(6))
print(randomNumber)

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Here's a simple unix2dos.bat file that preserves blank lines and exclamation points:

@echo off
setlocal DisableDelayedExpansion
for /f "tokens=1,* delims=:" %%k in ('findstr /n "^" %1') do echo.%%l

The output goes to standard out, so redirect unix2dos.bat output to a file if so desired.

It avoids the pitfalls of other previously proposed for /f batch loop solutions by:
1) Working with delayed expansion off, to avoid eating up exclamation marks.
2) Using the for /f tokenizer itself to remove the line number from the findstr /n output lines.
(Using findstr /n is necessary to also get blank lines: They would be dropped if for /f read directly from the input file.)

But, as Jeb pointed out in a comment below, the above solution has one drawback the others don't: It drops colons at the beginning of lines.

So 2020-04-06 update just for fun, here's another 1-liner based on findstr.exe, that seems to work fine without the above drawbacks:

@echo off
setlocal DisableDelayedExpansion
for /f "tokens=* delims=0123456789" %%l in ('findstr /n "^" %1') do echo%%l

The additional tricks are:
3) Use digits 0-9 as delimiters, so that tokens=* skips the initial line number.
4) Use the colon, inserted by findstr /n after the line number, as the token separator after the echo command.

I'll leave it to Jeb to explain if there are corner cases where echo:something might fail :-)
All I can say is that this last version successfully restored line endings on my huge batch library, so exceptions, if any, must be quite rare!

select min(sal) from (select distinct sal from employee order by sal DESC) where rownum<=N;

place the number whatever the highest sal you want to retrieve.

Identifiers are used for class names, method names, and variable names. An identifiermay be any descriptive sequence of uppercase and lowercase letters, numbers, or theunderscore and dollar-sign characters. They must not begin with a number, lest they beconfused with a numeric literal. Again, Java is case-sensitive, so VALUE is a differentidentifier than Value. Some examples of valid identifiers are:

AvgTemp ,count a4 ,$test ,this_is_ok

Invalid variable names include:

2count, high-temp, Not/ok

An array is a variable, so in that case mapfile will work

mapfile y <<'z'
abc'asdf"
$(dont-execute-this)
foo"bar"''
z

Then you can print like this

printf %s "${y[@]}"

You can use the .rows property and check it's .length, like this:

var rowCount = document.getElementById('myTableID').rows.length;

Try this:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

Notice that you have to work at least with 4.5 .NET framework

In XSLT the same <xsl:variable> can be declared only once and can be given a value only at its declaration. If more than one variables are declared at the same time, they are in fact different variables and have different scope.

Therefore, the way to achieve the wanted conditional setting of the variable and producing its value is the following:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

    <xsl:template match="class">
    <xsl:variable name="subexists">
            <xsl:choose>
                <xsl:when test="joined-subclass">true</xsl:when>
                <xsl:otherwise>false</xsl:otherwise>
            </xsl:choose>
        </xsl:variable>
        subexists:  <xsl:text/>    
        <xsl:value-of select="$subexists" />
    </xsl:template>
</xsl:stylesheet>

When the above transformation is applied on the following XML document:

<class>
 <joined-subclass/>
</class>

the wanted result is produced:

    subexists:  true

echo $myarray[0]->['email'];

Try this only if it you are passing the stdclass object

I just want to post my solution. Previous answers was pretty helpful for my research. I use length-stream to get the size of the stream, but the problem here is that the callback is fired near the end of the stream, so i also use stream-cache to cache the stream and pipe it to res object once i know the content-length. In case on an error,

var StreamCache = require('stream-cache');
var lengthStream = require('length-stream');

var _streamFile = function(res , stream , cb){
    var cache = new StreamCache();

    var lstream = lengthStream(function(length) {
        res.header("Content-Length", length);
        cache.pipe(res);
    });

    stream.on('error', function(err){
        return cb(err);
    });

    stream.on('end', function(){
        return cb(null , true);
    });

    return stream.pipe(lstream).pipe(cache);
}

You can use Calendar.getActualMaximum method:

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month);
int numDays = calendar.getActualMaximum(Calendar.DATE);

        Translate.Translations.List list = t.new Translations().list(
                Arrays.asList(
                        // Pass in list of strings to be translated
                        "Hello World",
                        "How to use Google Translate from Java"),
                // Target language
                "ES");

        // TODO: Set your API-Key from https://console.developers.google.com/
        list.setKey("your-api-key");
        TranslationsListResponse response = list.execute();
        for (TranslationsResource translationsResource : response.getTranslations())
        {

All the other answers are sufficient but for a large project like ours and where navigations are being made both in code and storyboard, it is quite a daunting task.

For those who are actively using Storyboard. This is my advice: use Regex.

The following format is not good for full screen pages:

<segue destination="Bof-iQ-svK" kind="presentation" identifier="importSystem" modalPresentationStyle="fullScreen" id="bfy-FP-mlc"/>

The following format is good for full screen pages:

<segue destination="7DQ-Kj-yFD" kind="presentation" identifier="defaultLandingToSystemInfo" modalPresentationStyle="fullScreen" id="Mjn-t2-yxe"/>

The following regex compatible with VS CODE will convert all Old Style pages to new style pages. You may need to escape special chars if you're using other regex engines/text editors.

Search Regex

<segue destination="(.*)"\s* kind="show" identifier="(.*)" id="(.*)"/>

Replace Regex

<segue destination="$1" kind="presentation" identifier="$2" modalPresentationStyle="fullScreen" id="$3"/>

Ends an iterator block (e.g. says there are no more elements in the IEnumerable).

You must close the project, hover over the project in the welcome screen, then press the delete button.

You can sort by values in reverse order (largest to smallest) using a dictionary comprehension:

{k: d[k] for k in sorted(d, key=d.get, reverse=True)}
# {'b': 4, 'a': 3, 'c': 2, 'd': 1}

If you want to sort by values in ascending order (smallest to largest)

{k: d[k] for k in sorted(d, key=d.get)}
# {'d': 1, 'c': 2, 'a': 3, 'b': 4}

If you want to sort by the keys in ascending order

{k: d[k] for k in sorted(d)}
# {'a': 3, 'b': 4, 'c': 2, 'd': 1}

This works on CPython 3.6+ and any implementation of Python 3.7+ because dictionaries keep insertion order.

This will print everything after each match, on that same line only:

perl -lne 'print $1 if /^potato:\s*(.*)/' file.txt

This will do the same, except it will also print all subsequent lines:

perl -lne 'if ($found){print} elsif (/^potato:\s*(.*)/){print $1; $found++}' file.txt

These command-line options are used:

• -n loop around each line of the input file
• -l removes newlines before processing, and adds them back in afterwards
• -e execute the perl code

If you are using jQuery you can easily fetch the data attributes by

$(this).data("id") or $(event.target).data("id")

You have probably defined $name, $date, $text or $date2 to be a string, like:

$name = 'String';

Then if you treat it like an array it will give that fatal error:

$name[] = 'new value'; // fatal error

To solve your problem just add the following code at the beginning of the loop:

$name = array();
$date = array();
$text = array();
$date2 = array();

This will reset their value to array and then you'll able to use them as arrays.

In the web development world, the term "redirect" is the act of sending the client an empty HTTP response with just a Location header containing the new URL to which the client has to send a brand new GET request. So basically:

• Client sends a HTTP request to some.jsp.
• Server sends a HTTP response back with Location: other.jsp header
• Client sends a HTTP request to other.jsp (this get reflected in browser address bar!)
• Server sends a HTTP response back with content of other.jsp.

You can track it with the web browser's builtin/addon developer toolset. Press F12 in Chrome/IE9/Firebug and check the "Network" section to see it.

Exactly the above is achieved by sendRedirect("other.jsp"). The RequestDispatcher#forward() doesn't send a redirect. Instead, it uses the content of the target page as HTTP response.

• Client sends a HTTP request to some.jsp.
• Server sends a HTTP response back with content of other.jsp.

However, as the original HTTP request was to some.jsp, the URL in browser address bar remains unchanged. Also, any request attributes set in the controller behind some.jsp will be available in other.jsp. This does not happen during a redirect because you're basically forcing the client to create a new HTTP request on other.jsp, hereby throwing away the original request on some.jsp including all of its attribtues.

The RequestDispatcher is extremely useful in the MVC paradigm and/or when you want to hide JSP's from direct access. You can put JSP's in the /WEB-INF folder and use a Servlet which controls, preprocesses and postprocesses the requests. The JSPs in the /WEB-INF folder are not directly accessible by URL, but the Servlet can access them using RequestDispatcher#forward().

You can for example have a JSP file in /WEB-INF/login.jsp and a LoginServlet which is mapped on an url-pattern of /login. When you invoke http://example.com/context/login, then the servlet's doGet() will be invoked. You can do any preprocessing stuff in there and finally forward the request like:

request.getRequestDispatcher("/WEB-INF/login.jsp").forward(request, response);

When you submit a form, you normally want to use POST:

<form action="login" method="post">

This way the servlet's doPost() will be invoked and you can do any postprocessing stuff in there (e.g. validation, business logic, login the user, etc).

If there are any errors, then you normally want to forward the request back to the same page and display the errors there next to the input fields and so on. You can use the RequestDispatcher for this.

If a POST is successful, you normally want to redirect the request, so that the request won't be resubmitted when the user refreshes the request (e.g. pressing F5 or navigating back in history).

User user = userDAO.find(username, password);
if (user != null) {
    request.getSession().setAttribute("user", user); // Login user.
    response.sendRedirect("home"); // Redirects to http://example.com/context/home after succesful login.
} else {
    request.setAttribute("error", "Unknown login, please try again."); // Set error.
    request.getRequestDispatcher("/WEB-INF/login.jsp").forward(request, response); // Forward to same page so that you can display error.
}

A redirect thus instructs the client to fire a new GET request on the given URL. Refreshing the request would then only refresh the redirected request and not the initial request. This will avoid "double submits" and confusion and bad user experiences. This is also called the POST-Redirect-GET pattern.

Python 3

In Python 3, this question doesn't apply. The plain int type is unbounded.

However, you might actually be looking for information about the current interpreter's word size, which will be the same as the machine's word size in most cases. That information is still available in Python 3 as sys.maxsize, which is the maximum value representable by a signed word. Equivalently, it's the size of the largest possible list or in-memory sequence.

Generally, the maximum value representable by an unsigned word will be sys.maxsize * 2 + 1, and the number of bits in a word will be math.log2(sys.maxsize * 2 + 2). See this answer for more information.

Python 2

In Python 2, the maximum value for plain int values is available as sys.maxint:

>>> sys.maxint
9223372036854775807

You can calculate the minimum value with -sys.maxint - 1 as shown here.

Python seamlessly switches from plain to long integers once you exceed this value. So most of the time, you won't need to know it.

You cannot push anything that hasn't been committed yet. The order of operations is:

1. Make your change.
2. git add - this stages your changes for committing
3. git commit - this commits your staged changes locally
4. git push - this pushes your committed changes to a remote

If you push without committing, nothing gets pushed. If you commit without adding, nothing gets committed. If you add without committing, nothing at all happens, git merely remembers that the changes you added should be considered for the following commit.

The message you're seeing (your branch is ahead by 1 commit) means that your local repository has one commit that hasn't been pushed yet.

In other words: add and commit are local operations, push, pull and fetch are operations that interact with a remote.

Since there seems to be an official source control workflow in place where you work, you should ask internally how this should be handled.

Here is the simplest way to do it with CSS3:

#mybox:hover {
  color: transparent;
}

regardless of the container color you can make the text color transparent on hover.

In Javascript method names are camel case, so it's replace, not Replace:

$scope.newString = oldString.replace("stackover","NO");

Note that contrary to how the .NET Replace method works, the Javascript replace method replaces only the first occurrence if you are using a string as first parameter. If you want to replace all occurrences you need to use a regular expression so that you can specify the global (g) flag:

$scope.newString = oldString.replace(/stackover/g,"NO");

See this example.

one elegant way to do this is to represent items in the list as string holding a dot separated list of parents, and finally a value:

server.port=90
server.hostname=localhost
client.serverport=90
client.database.port=1234
client.database.host=localhost

When assembling a tree, you would end up with something like:

server:
  port: 90
  hostname: localhost
client:
  serverport=1234
  database:
    port: 1234
    host: localhost

I have a configuration library that implements this override configuration (tree) from command line arguments (list). The algorithm to add a single item to the list to a tree is here.

Overview

• const guarantees that a program does not change an object’s value. However, const does not guarantee which type of initialization the object undergoes.

  Consider:

  const int mx = numeric_limits<int>::max();  // OK: runtime initialization
  

  The function max() merely returns a literal value. However, because the initializer is a function call, mx undergoes runtime initialization. Therefore, you cannot use it as a constant expression:

  int arr[mx];  // error: “constant expression required”
  

• constexpr is a new C++11 keyword that rids you of the need to create macros and hardcoded literals. It also guarantees, under certain conditions, that objects undergo static initialization. It controls the evaluation time of an expression. By enforcing compile-time evaluation of its expression, constexpr lets you define true constant expressions that are crucial for time-critical applications, system programming, templates, and generally speaking, in any code that relies on compile-time constants.

Constant-expression functions

A constant-expression function is a function declared constexpr. Its body must be non-virtual and consist of a single return statement only, apart from typedefs and static asserts. Its arguments and return value must have literal types. It can be used with non-constant-expression arguments, but when that is done the result is not a constant expression.

A constant-expression function is meant to replace macros and hardcoded literals without sacrificing performance or type safety.

constexpr int max() { return INT_MAX; }           // OK
constexpr long long_max() { return 2147483647; }  // OK
constexpr bool get_val()
{
    bool res = false;
    return res;
}  // error: body is not just a return statement

constexpr int square(int x)
{ return x * x; }  // OK: compile-time evaluation only if x is a constant expression
const int res = square(5);  // OK: compile-time evaluation of square(5)
int y = getval();
int n = square(y);          // OK: runtime evaluation of square(y)

Constant-expression objects

A constant-expression object is an object declared constexpr. It must be initialized with a constant expression or an rvalue constructed by a constant-expression constructor with constant-expression arguments.

A constant-expression object behaves as if it was declared const, except that it requires initialization before use and its initializer must be a constant expression. Consequently, a constant-expression object can always be used as part of another constant expression.

struct S
{
    constexpr int two();      // constant-expression function
private:
    static constexpr int sz;  // constant-expression object
};
constexpr int S::sz = 256;
enum DataPacket
{
    Small = S::two(),  // error: S::two() called before it was defined
    Big = 1024
};
constexpr int S::two() { return sz*2; }
constexpr S s;
int arr[s.two()];  // OK: s.two() called after its definition

Constant-expression constructors

A constant-expression constructor is a constructor declared constexpr. It can have a member initialization list but its body must be empty, apart from typedefs and static asserts. Its arguments must have literal types.

A constant-expression constructor allows the compiler to initialize the object at compile-time, provided that the constructor’s arguments are all constant expressions.

struct complex
{
    // constant-expression constructor
    constexpr complex(double r, double i) : re(r), im(i) { }  // OK: empty body
    // constant-expression functions
    constexpr double real() { return re; }
    constexpr double imag() { return im; }
private:
    double re;
    double im;
};
constexpr complex COMP(0.0, 1.0);         // creates a literal complex
double x = 1.0;
constexpr complex cx1(x, 0);              // error: x is not a constant expression
const complex cx2(x, 1);                  // OK: runtime initialization
constexpr double xx = COMP.real();        // OK: compile-time initialization
constexpr double imaglval = COMP.imag();  // OK: compile-time initialization
complex cx3(2, 4.6);                      // OK: runtime initialization

Tips from the book Effective Modern C++ by Scott Meyers about constexpr:

• constexpr objects are const and are initialized with values known during compilation;
• constexpr functions produce compile-time results when called with arguments whose values are known during compilation;
• constexpr objects and functions may be used in a wider range of contexts than non-constexpr objects and functions;
• constexpr is part of an object’s or function’s interface.

As stated in seong's comment:

Also see http://golang.org/doc/effective_go.html#maps. The important part is really the "reference to underlying data structure". This also applies to slices.

However, none of the solutions here seem to offer a solution for a proper deep copy that also covers slices.

I've slightly altered Francesco Casula's answer to accommodate for both maps and slices.

This should cover both copying your map itself, as well as copying any child maps or slices. Both of which are affected by the same "underlying data structure" issue. It also includes a utility function for performing the same type of Deep Copy on a slice directly.

Keep in mind that the slices in the resulting map will be of type []interface{}, so when using them, you will need to use type assertion to retrieve the value in the expected type.

Example Usage

copy := CopyableMap(originalMap).DeepCopy()

Source File (util.go)

package utils

type CopyableMap   map[string]interface{}
type CopyableSlice []interface{}

// DeepCopy will create a deep copy of this map. The depth of this
// copy is all inclusive. Both maps and slices will be considered when
// making the copy.
func (m CopyableMap) DeepCopy() map[string]interface{} {
    result := map[string]interface{}{}

    for k,v := range m {
        // Handle maps
        mapvalue,isMap := v.(map[string]interface{})
        if isMap {
            result[k] = CopyableMap(mapvalue).DeepCopy()
            continue
        }

        // Handle slices
        slicevalue,isSlice := v.([]interface{})
        if isSlice {
            result[k] = CopyableSlice(slicevalue).DeepCopy()
            continue
        }

        result[k] = v
    }

    return result
}

// DeepCopy will create a deep copy of this slice. The depth of this
// copy is all inclusive. Both maps and slices will be considered when
// making the copy.
func (s CopyableSlice) DeepCopy() []interface{} {
    result := []interface{}{}

    for _,v := range s {
        // Handle maps
        mapvalue,isMap := v.(map[string]interface{})
        if isMap {
            result = append(result, CopyableMap(mapvalue).DeepCopy())
            continue
        }

        // Handle slices
        slicevalue,isSlice := v.([]interface{})
        if isSlice {
            result = append(result, CopyableSlice(slicevalue).DeepCopy())
            continue
        }

        result = append(result, v)
    }

    return result
}

Test File (util_tests.go)

package utils

import (
    "testing"

    "github.com/stretchr/testify/require"
)

func TestCopyMap(t *testing.T) {
    m1 := map[string]interface{}{
        "a": "bbb",
        "b": map[string]interface{}{
            "c": 123,
        },
        "c": []interface{} {
            "d", "e", map[string]interface{} {
                "f": "g",
            },
        },
    }

    m2 := CopyableMap(m1).DeepCopy()

    m1["a"] = "zzz"
    delete(m1, "b")
    m1["c"].([]interface{})[1] = "x"
    m1["c"].([]interface{})[2].(map[string]interface{})["f"] = "h"

    require.Equal(t, map[string]interface{}{
        "a": "zzz", 
        "c": []interface{} {
            "d", "x", map[string]interface{} {
                "f": "h",
            },
        },
    }, m1)
    require.Equal(t, map[string]interface{}{
        "a": "bbb",
        "b": map[string]interface{}{
            "c": 123,
        },
        "c": []interface{} {
            "d", "e", map[string]interface{} {
                "f": "g",
            },
        },
    }, m2)
}

Using OVER() and LIMIT 1:

SELECT COUNT(1) OVER()
FROM posts 
   INNER JOIN votes ON votes.post_id = posts.id 
GROUP BY posts.id
LIMIT 1;

Yes, you could make an indexer on your Record class that maps from the property name to the correct property. This would keep all the binding from property name to property in one place eg:

public class Record
{
    public string ItemType { get; set; }

    public string this[string propertyName]
    {
        set
        {
            switch (propertyName)
            {
                case "itemType":
                    ItemType = value;
                    break;
                    // etc
            }   
        }
    }
}

Alternatively, as others have mentioned, use reflection.

Follow these steps to run your application on the device connected. 1. Change directories to the root of your Android project and execute: ant debug 2. Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute: adb install bin/<*your app name*>-debug.apk On your device, locate <*your app name*> and open it.

I was having the same trouble with importing from Excel 2010 to Access, appending an "identical" table. Early on in the wizard it said not all my column names were valid, even though I checked them. It turns out that it saw an "empty" column with no column name. When I tried using the import wizard to create a new table instead, it worked. However, I noticed that it had added a blank column to the right of my data and called it "Field30". So I went back to the spreadsheet I was trying to import, selected the columns to the right of the data that I wanted, right-clicked and chose "clear contents." That did the trick and I was able to import the spreadsheet, appending it to my table.

date.setTime( date.getTime() + days * 86400000 );

I think the question is getting at the fact that C# needs another keyword, for precisely this sort of situation. You want a method whose return value depends only on the type on which it is called. You can't call it "static" if said type is unknown. But once the type becomes known, it will become static. "Unresolved static" is the idea -- it's not static yet, but once we know the receiving type, it will be. This is a perfectly good concept, which is why programmers keep asking for it. But it didn't quite fit into the way the designers thought about the language.

Since it's not available, I have taken to using non-static methods in the way shown below. Not exactly ideal, but I can't see any approach that makes more sense, at least not for me.

public interface IZeroWrapper<TNumber> {
  TNumber Zero {get;}
}

public class DoubleWrapper: IZeroWrapper<double> {
  public double Zero { get { return 0; } }
}

I have scopes for this, hope it help somebody. https://laravel.com/docs/master/eloquent#local-scopes

public function scopeWhereLike($query, $column, $value)
{
    return $query->where($column, 'like', '%'.$value.'%');
}

public function scopeOrWhereLike($query, $column, $value)
{
    return $query->orWhere($column, 'like', '%'.$value.'%');
}

Usage:

$result = BookingDates::whereLike('email', $email)->orWhereLike('name', $name)->get();

Hint: break up the 32-bit integer to 4 8-bit integers, and print them out.

Something along the lines of this (not compiled, YMMV):

int i = 0xDEADBEEF; // some 32-bit integer
printf("%i.%i.%i.%i",
          (i >> 24) & 0xFF,
          (i >> 16) & 0xFF,
          (i >> 8) & 0xFF,
          i & 0xFF);

For this you can use CSS3 background-size property. Write like this:

#div2{
    background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
    -moz-background-size:100% 100%;
    -webkit-background-size:100% 100%;
    background-size:100% 100%;
    height:180px;
    width:200px;
    border: 1px solid red;
}

Check this: http://jsfiddle.net/qdzaw/1/

You need the :not() selector:

$('div[class^="first-"]:not(.first-bar)')

or, alternatively, the .not() method:

$('div[class^="first-"]').not('.first-bar');

It seems like you are essentially looking into computing the z-score or standard score of your data, which is calculated through the formula: z = (x-mean(x))/std(x)

This should work:

%% Original data (Normal with mean 1 and standard deviation 2)
x = 1 + 2*randn(100,1);
mean(x)
var(x)
std(x)

%% Normalized data with mean 0 and variance 1
z = (x-mean(x))/std(x);
mean(z)
var(z)
std(z)

you can make that using transform and transform origins.

Combining various transfroms gives similar result. I hope you find it helpful. :) See these examples for simpler transforms. this has left point :

what transform: 0% 50%; does is it sets the origin to vertical middle and horizontal left of the element. so the perspective is not visible at the left part of the image, so it looks flat. Perspective effect is there at the right part, so it looks slanted.

I faced a similar problem. I tried everything with ports, hosts and config files.But nothing helped.

I checked apache error logs. They showed the following error

(OS 10038)An operation was attempted on something that is not a socket.  : AH00332: winnt_accept: getsockname error on listening socket, is IPv6 available?

Finally this is what solved my problem.

1) Goto command prompt and run it in administrative mode. In windows 7 you can do it by typing cmd in run and then pressing ctrl+shift+enter

2) run the following command: netsh winsock reset

3) Restart the system

Here is the pure Javascript version of it with LIVE search for ALL COLUMNS :

function search_table(){
  // Declare variables

  input = document.getElementById("search_field_input");
  filter = input.value.toUpperCase();
  table = document.getElementById("table_id");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those who don't match the search query
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td") ; 
    for(j=0 ; j<td.length ; j++)
    {
      let tdata = td[j] ;
      if (tdata) {
        if (tdata.innerHTML.toUpperCase().indexOf(filter) > -1) {
          tr[i].style.display = "";
          break ; 
        } else {
          tr[i].style.display = "none";
        }
      } 
    }
  }
}

The following code helped me resolve the issue. The path to the template needs to be provided as part of file.resource.loader path. By default it comes as "." . So setting the property explicitly will be required.

Print getClass().getClassLoader().getResource("resources") or getClass().getClassLoader().getResource("") to see where your template comes and based on that set it in the velocity template engine.

URL url = getClass().getClassLoader().getResource("resources");
//URL url = getClass().getClassLoader().getResource("");
File folder= new File(url.getFile());   
VelocityEngine ve = new VelocityEngine();
       
ve.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, folder.getAbsolutePath());
ve.init();

Template template = ve.getTemplate( "MyTemplate.vm" );

FYI, I combined Keremk's answer with my original outline, cleaned-up the typos, generalized it to return an array of colors and got the whole thing to compile. Here is the result:

+ (NSArray*)getRGBAsFromImage:(UIImage*)image atX:(int)x andY:(int)y count:(int)count
{
    NSMutableArray *result = [NSMutableArray arrayWithCapacity:count];

    // First get the image into your data buffer
    CGImageRef imageRef = [image CGImage];
    NSUInteger width = CGImageGetWidth(imageRef);
    NSUInteger height = CGImageGetHeight(imageRef);
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    unsigned char *rawData = (unsigned char*) calloc(height * width * 4, sizeof(unsigned char));
    NSUInteger bytesPerPixel = 4;
    NSUInteger bytesPerRow = bytesPerPixel * width;
    NSUInteger bitsPerComponent = 8;
    CGContextRef context = CGBitmapContextCreate(rawData, width, height,
                    bitsPerComponent, bytesPerRow, colorSpace,
                    kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
    CGColorSpaceRelease(colorSpace);

    CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
    CGContextRelease(context);

    // Now your rawData contains the image data in the RGBA8888 pixel format.
    NSUInteger byteIndex = (bytesPerRow * y) + x * bytesPerPixel;
    for (int i = 0 ; i < count ; ++i)
    {
        CGFloat alpha = ((CGFloat) rawData[byteIndex + 3] ) / 255.0f;

HttpVerb needs its headers as a dictionary of key-value pairs

I have used both JXL (now "JExcel") and Apache POI. At first I used JXL, but now I use Apache POI.

First, here are the things where both APIs have the same end functionality:

• Both are free
• Cell styling: alignment, backgrounds (colors and patterns), borders (types and colors), font support (font names, colors, size, bold, italic, strikeout, underline)
• Formulas
• Hyperlinks
• Merged cell regions
• Size of rows and columns
• Data formatting: Numbers and Dates
• Text wrapping within cells
• Freeze Panes
• Header/Footer support
• Read/Write existing and new spreadsheets
• Both attempt to keep existing objects in spreadsheets they read in intact as far as possible.

However, there are many differences:

• Perhaps the most significant difference is that Java JXL does not support the Excel 2007+ ".xlsx" format; it only supports the old BIFF (binary) ".xls" format. Apache POI supports both with a common design.
• Additionally, the Java portion of the JXL API was last updated in 2009 (3 years, 4 months ago as I write this), although it looks like there is a C# API. Apache POI is actively maintained.
• JXL doesn't support Conditional Formatting, Apache POI does, although this is not that significant, because you can conditionally format cells with your own code.
• JXL doesn't support rich text formatting, i.e. different formatting within a text string; Apache POI does support it.
• JXL only supports certain text rotations: horizontal/vertical, +/- 45 degrees, and stacked; Apache POI supports any integer number of degrees plus stacked.
• JXL doesn't support drawing shapes; Apache POI does.
• JXL supports most Page Setup settings such as Landscape/Portrait, Margins, Paper size, and Zoom. Apache POI supports all of that plus Repeating Rows and Columns.
• JXL doesn't support Split Panes; Apache POI does.
• JXL doesn't support Chart creation or manipulation; that support isn't there yet in Apache POI, but an API is slowly starting to form.
• Apache POI has a more extensive set of documentation and examples available than JXL.

Additionally, POI contains not just the main "usermodel" API, but also an event-based API if all you want to do is read the spreadsheet content.

In conclusion, because of the better documentation, more features, active development, and Excel 2007+ format support, I use Apache POI.

git pull origin master

this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.

The best way is to use mpack!

mpack -s "Subject" -d "./body.txt" "././image.png" mailadress

mpack - subject - body - attachment - mailadress

I send you an example with swiftmailer:

parameters.yml

recipients: [email1, email2, email3]

services:

your_service_name:
        class: your_namespace
        arguments: ["%recipients%"]

the class of the service:

protected $recipients;

public function __construct($recipients)
{
    $this->recipients = $recipients;
}

Try like this as well

covertPostSub("/xyz/test.jsp","?param1=param1&param2=param2","_self","true");
covertPostSub("/xyz/test.jsp","?param1=param1&param2=param2","_blank","true");

var convPop = null;
function covertPostSub(action,paramsTosend,targetIframe,isWindow){
    var Popup = null;
    var form = document.createElement("form");
    form.setAttribute("method", "POST");
    form.setAttribute("id","TheForm");
    form.setAttribute("action", action);
    form.setAttribute("target", targetIframe);
    var params = paramsTosend;
    params = params.substring(1, params.length);
    params = params.split("&");
    for(var key=0; key<params.length; key++) {
        var sa = params[key];
        sa = sa.split("=");
        var xs = (sa[1]);

        if(params.hasOwnProperty(key)) {
            var hiddenField = document.createElement("input");
            hiddenField.setAttribute("type", "hidden");
            hiddenField.setAttribute("name", sa[0]);
            hiddenField.setAttribute("value",xs);

            form.appendChild(hiddenField);
         }
    }
    document.body.appendChild(form);
    form.style.display = "none";
    if(isWindow){
        window.open('', "formpopup","width=900,height=590,toolbar=no,scrollbars=yes,resizable=no,location=0,directories=0,status=1,menubar=0,left=60,top=60");
        form.target = 'formpopup';
        form.submit();
    }else{
        form.submit();
    }

}

In FF also CSS filter works fine. E.g. hue-rotate:

option {
    filter: hue-rotate(90deg);
}

If you want to show error messages on form submission, you can use condition form.$submitted to check if an attempt was made to submit the form. Check following example.

<form name="myForm" novalidate ng-submit="myForm.$valid && createUser()">
  <input type="text" name="name" ng-model="user.name" placeholder="Enter name of user" required>
  <div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
    <div ng-message="required">Please enter user name.</div>
  </div>

  <input type="text" name="address" ng-model="user.address" placeholder="Enter Address" required ng-maxlength="30">
  <div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
    <div ng-message="required">Please enter user address.</div>
    <div ng-message="maxlength">Should be less than 30 chars</div>
  </div>

  <button type="submit">
    Create user
  </button>
</form>

I had a similar issue where I would try to call reverse('admin_index') and was constantly getting django.core.urlresolvers.NoReverseMatch errors.

Turns out I had the old format admin urls in my urls.py file.

I had this in my urlpatterns:

(r'^admin/(.*)', admin.site.root),

which gets the admin screens working but is the deprecated way of doing it. I needed to change it to this:

(r'^admin/', include(admin.site.urls) ),

Once I did that, all the goodness that was promised in the Reversing Admin URLs docs started working.

Sharer.php no longer allows you to customize. The page you share will be scraped for OG Tags and that data will be shared.

To properly customize, use FB.UI which comes with the JS-SDK.

Loading local JSON file

Use something like this

$.getJSON("../../data/file.json", function(json) {
    console.log(json); // this will show the info in firebug console 
    alert(json);
});

A function can be created in order to check for visibility/display attributes in order to gauge whether the element is shown in the UI or not.

function checkUIElementVisible(element) {
    return ((element.css('display') !== 'none') && (element.css('visibility') !== 'hidden'));
}

Working Fiddle

htons is host-to-network short

This means it works on 16-bit short integers. i.e. 2 bytes.

This function swaps the endianness of a short.

Your number starts out at:

0001 0011 1000 1001 = 5001

When the endianness is changed, it swaps the two bytes:

1000 1001 0001 0011 = 35091

You can filter version from the MANIFEST file using

unzip -p my.jar META-INF/MANIFEST.MF | grep 'Bundle-Version'

(update: As of March 2020, many people have reported that yolk, installed via pip install yolk3k, only returns latest version. Chris's answer seems to have the most upvotes and worked for me)

The script at pastebin does work. However it's not very convenient if you're working with multiple environments/hosts because you will have to copy/create it every time.

A better all-around solution would be to use yolk3k, which is available to install with pip. E.g. to see what versions of Django are available:

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

yolk3k is a fork of the original yolk which ceased development in 2012. Though yolk is no longer maintained (as indicated in comments below), yolk3k appears to be and supports Python 3.

Note: I am not involved in the development of yolk3k. If something doesn't seem to work as it should, leaving a comment here should not make much difference. Use the yolk3k issue tracker instead and consider submitting a fix, if possible.

I had this problem (403 error for each package) and I found nothing great in the internet to solve it. My .npmrc file inside my user folder was wrong and misunderstood. I changed this npmrc line from

proxy=http://XX.XX.XXX.XXX:XXX/

to :

proxy = XX.XX.XXX.XXX:XXXX

The first one takes two parameters:

parseInt(string, radix)

The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.

If the radix parameter is omitted, JavaScript assumes the following:

• If the string begins with "0x", the
  radix is 16 (hexadecimal)
• If the string begins with "0", the radix is 8 (octal). This feature
  is deprecated
• If the string begins with any other value, the radix is 10 (decimal)

The other function you mentioned takes only one parameter:

Number(object)

The Number() function converts the object argument to a number that represents the object's value.

If the value cannot be converted to a legal number, NaN is returned.

Try or:

WHERE id = 3 or id = 4

Or the equivalent in:

WHERE id in (3,4)

Firstly, you need to install pip for the Python 3 installation that you want. Then you run that pip to install packages for that Python version.

Since you have both pip and python 3 in /usr/bin, I assume they are both installed with a package manager of some sort. That package manager should also have a Python 3 pip. That's the one you should install.

Felix' recommendation of virtualenv is a good one. If you are only testing, or you are doing development, then you shouldn't install the package in the system python. Using virtualenv, or even building your own Pythons for development, is better in those cases.

But if you actually do want to install this package in the system python, installing pip for Python 3 is the way to go.

In case someone has a similar issue. My resolution was to delete the key that was not working and got a new key for my domain. And this now works with all my sub-domains as well without having to explicitly specify them in the recaptcha admin area.

Actually, if you try to use function "children" it will not be succesfull because it's possible to the table has a first child like 'th'. So you have to use function 'find' instead.

Wrong way:

var $row = $(this).closest('table').children('tr:first');

Correct way:

 var $row = $(this).closest('table').find('tr:first');

Particularly for node, the documentation for the http server component, under event connection says:

[Triggered] when a new TCP stream is established. [The] socket is an object of type net.Socket. Usually users will not want to access this event. In particular, the socket will not emit readable events because of how the protocol parser attaches to the socket. The socket can also be accessed at request.connection.

So, that means request.connection is a socket and according to the documentation there is indeed a socket.remoteAddress attribute which according to the documentation is:

The string representation of the remote IP address. For example, '74.125.127.100' or '2001:4860:a005::68'.

Under express, the request object is also an instance of the Node http request object, so this approach should still work.

However, under Express.js the request already has two attributes: req.ip and req.ips

req.ip

Return the remote address, or when "trust proxy" is enabled - the upstream address.

req.ips

When "trust proxy" is true, parse the "X-Forwarded-For" ip address list and return an array, otherwise an empty array is returned. For example if the value were "client, proxy1, proxy2" you would receive the array ["client", "proxy1", "proxy2"] where "proxy2" is the furthest down-stream.

It may be worth mentioning that, according to my understanding, the Express req.ip is a better approach than req.connection.remoteAddress, since req.ip contains the actual client ip (provided that trusted proxy is enabled in express), whereas the other may contain the proxy's IP address (if there is one).

That is the reason why the currently accepted answer suggests:

var ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;

The req.headers['x-forwarded-for'] will be the equivalent of express req.ip.

An XML declaration is not required in all XML documents; however XHTML document authors are strongly encouraged to use XML declarations in all their documents. Such a declaration is required when the character encoding of the document is other than the default UTF-8 or UTF-16 and no encoding was determined by a higher-level protocol. Here is an example of an XHTML document. In this example, the XML declaration is included.

To answer your question, you should know the difference between malloc and new. The difference is simple:

malloc allocates memory, while new allocates memory AND calls the constructor of the object you're allocating memory for.

So, unless you're restricted to C, you should never use malloc, especially when dealing with C++ objects. That would be a recipe for breaking your program.

Also the difference between free and delete is quite the same. The difference is that delete will call the destructor of your object in addition to freeing memory.

For those of you who faced this issue while creating a controller through the context menu, reopening Visual Studio as an administrator fixed it.

You can use this code when using vs code on debugging mode.

How about this?

CREATE FUNCTION dbo.StripWWWandCom (@input VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @Work VARCHAR(250)

    SET @Work = @Input

    SET @Work = REPLACE(@Work, 'www.', '')
    SET @Work = REPLACE(@Work, '.com', '')

    RETURN @work
END

and then use:

SELECT ID, dbo.StripWWWandCom (WebsiteName)
FROM dbo.YourTable .....

Of course, this is severely limited in that it will only strip www. at the beginning and .com at the end - nothing else (so it won't work on other host machine names like smtp.yahoo.com and other internet domains such as .org, .edu, .de and etc.)

Looks like you are running afoul of this rule for updating views from Books Online: "INSERT statements must specify values for any columns in the underlying table that do not allow null values and have no DEFAULT definitions."

The Watcher method fires on every character input. So, I built this code based on onFocusChange method:

public static boolean comS(String s1,String s2){
    if (s1.length()==s2.length()){
        int l=s1.length();
        for (int i=0;i<l;i++){
            if (s1.charAt(i)!=s2.charAt(i))return false;
        }
        return true;
    }
    return false;
}

public void onChange(final EditText EdTe, final Runnable FRun){
    class finalS{String s="";}
    final finalS dat=new finalS();  
    EdTe.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {dat.s=""+EdTe.getText();}
            else if (!comS(dat.s,""+EdTe.getText())){(new Handler()).post(FRun);}       
        }
    });
}

To using it, just call like this:

onChange(YourEditText, new Runnable(){public void run(){
    // V  V    YOUR WORK HERE

    }}
);

You can ignore the comS function by replace the !comS(dat.s,""+EdTe.getText()) with !equal function. However the equal function itself some time work not correctly in run time.

The onChange listener will remember old data of EditText when user focus typing, and then compare the new data when user lose focus or jump to other input. If comparing old String not same new String, it fires the work.

If you only have 1 EditText, then u will need to make a ClearFocus function by making an Ultimate Secret Transparent Micro EditText outside the windows and request focus to it, then hide the keyboard via Import Method Manager.

After much pain, and great assistance from @vitr et al above, i decided to try

• standard bash substitution
• shell form of ENTRYPOINT (great tip from above)

and that worked.

ENV LISTEN_PORT=""

ENTRYPOINT java -cp "app:app/lib/*" hello.Application --server.port=${LISTEN_PORT:-80}

e.g.

docker run --rm -p 8080:8080 -d --env LISTEN_PORT=8080 my-image

and

docker run --rm -p 8080:80 -d my-image

both set the port correctly in my container

I had the same problem. Thank you to everyone else who answered - I was able to get a solution together using parts of several of these answers.

My solution is using swift 5

The problem that we are trying to solve is that we may have images with different aspect ratios in our TableViewCells but we want them to render with consistent widths. The images should, of course, render with no distortion and fill the entire space. In my case, I was fine with some "cropping" of tall, skinny images, so I used the content mode .scaleAspectFill

To do this, I created a custom subclass of UITableViewCell. In my case, I named it StoryTableViewCell. The entire class is pasted below, with comments inline.

This approach worked for me when also using a custom Accessory View and long text labels. Here's an image of the final result:

Rendered Table View with consistent image width

class StoryTableViewCell: UITableViewCell {

    override func layoutSubviews() {
        super.layoutSubviews()

        // ==== Step 1 ====
        // ensure we have an image
        guard let imageView = self.imageView else {return}

        // create a variable for the desired image width
        let desiredWidth:CGFloat = 70;

        // get the width of the image currently rendered in the cell
        let currentImageWidth = imageView.frame.size.width;

        // grab the width of the entire cell's contents, to be used later
        let contentWidth = self.contentView.bounds.width

        // ==== Step 2 ====
        // only update the image's width if the current image width isn't what we want it to be
        if (currentImageWidth != desiredWidth) {
            //calculate the difference in width
            let widthDifference = currentImageWidth - desiredWidth;

            // ==== Step 3 ====
            // Update the image's frame,
            // maintaining it's original x and y values, but with a new width
            self.imageView?.frame = CGRect(imageView.frame.origin.x,
                                           imageView.frame.origin.y,
                                           desiredWidth,
                                           imageView.frame.size.height);

            // ==== Step 4 ====
            // If there is a texst label, we want to move it's x position to
            // ensure it isn't overlapping with the image, and that it has proper spacing with the image
            if let textLabel = self.textLabel
            {
                let originalFrame = self.textLabel?.frame

                // the new X position for the label is just the original position,
                // minus the difference in the image's width
                let newX = textLabel.frame.origin.x - widthDifference
                self.textLabel?.frame = CGRect(newX,
                                               textLabel.frame.origin.y,
                                               contentWidth - newX,
                                               textLabel.frame.size.height);
                print("textLabel info: Original =\(originalFrame!)", "updated=\(self.textLabel!.frame)")
            }

            // ==== Step 4 ====
            // If there is a detail text label, do the same as step 3
            if let detailTextLabel = self.detailTextLabel {
                let originalFrame = self.detailTextLabel?.frame
                let newX = detailTextLabel.frame.origin.x-widthDifference
                self.detailTextLabel?.frame = CGRect(x: newX,
                                                     y: detailTextLabel.frame.origin.y,
                                                     width: contentWidth - newX,
                                                     height: detailTextLabel.frame.size.height);
                print("detailLabel info: Original =\(originalFrame!)", "updated=\(self.detailTextLabel!.frame)")
            }

            // ==== Step 5 ====
            // Set the image's content modoe to scaleAspectFill so it takes up the entire view, but doesn't get distorted
            self.imageView?.contentMode = .scaleAspectFill;
        }
    }
}

What I understand is you want same connection string with different Metadata in it. So you can use a connectionstring as given below and replace "" part. I have used your given connectionString in same sequence.

connectionString="<METADATA>provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True&quot;"

For first connectionString replace <METADATA> with "metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;"

For second connectionString replace <METADATA> with "metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;"

For third connectionString replace <METADATA> with "metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl|res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;"

Happy coding!

Turns out that I just have to convert @column name testName to all small letters, since it was initially in camel case.

Although I was not able to use the official answer, the question was able to help me solve my problem by letting me know what to investigate.

Change:

@Column(name="testName")
private String testName;

To:

@Column(name="testname")
private String testName;

If you need to write semantically correct mark-up, even in HTML5, you must not use ' to escape single quotes. Although, I can imagine you actually meant apostrophe rather then single quote.

single quotes and apostrophes are not the same, semantically, although they might look the same.

Here's one apostrophe.

Use ' to insert it if you need HTML4 support. (edited)

In British English, single quotes are used like this:

"He told me to 'give it a try'", I said.

Quotes come in pairs. You can use:

<p><q>He told me to <q>give it a try</q></q>, I said.<p>

to have nested quotes in a semantically correct way, deferring the substitution of the actual characters to the rendering engine. This substitution can then be affected by CSS rules, like:

q {
  quotes: '"' '"' '<' '>';
} 

An old but seemingly still relevant article about semantically correct mark-up: The Trouble With EM ’n EN (and Other Shady Characters).

(edited) This used to be:

Use ’ to insert it if you need HTML4 support.

But, as @James_pic pointed out, that is not the straight single quote, but the "Single curved quote, right".

In Bootstrap 4:

class="font-weight-bold"

Or:

<strong>text</strong>

Bootstrap 3

Using Bootstrap 3's grid system:

<div class="container">
  <div class="row">
    <div class="col-xs-4">Menu</div>
    <div class="col-xs-8">
      <div class="row">
        <div class="col-md-4 col-md-push-8">Right Content</div>
        <div class="col-md-8 col-md-pull-4">Content</div>
      </div>
    </div>
  </div>
</div>

Working example: http://bootply.com/93614

Explanation

First, we set two columns that will stay in place no matter the screen resolution (col-xs-*).

Next, we divide the larger, right hand column in to two columns that will collapse on top of each other on tablet sized devices and lower (col-md-*).

Finally, we shift the display order using the matching class (col-md-[push|pull]-*). You push the first column over by the amount of the second, and pull the second by the amount of the first.

And tick Set locale environment variables on startup.

Because, at least in HTML 4.01 and XHTML 1(.1), the type attribute for <script> elements is required.

In HTML 5, type is no longer required.

In fact, while you should use text/javascript in your HTML source, many servers will send the file with Content-type: application/javascript. Read more about these MIME types in RFC 4329.

Notice the difference between RFC 4329, that marked text/javascript as obsolete and recommending the use of application/javascript, and the reality in which some browsers freak out on <script> elements containing type="application/javascript" (in HTML source, not the HTTP Content-type header of the file that gets send). Recently, there was a discussion on the WHATWG mailing list about this discrepancy (HTML 5's type defaults to text/javascript), read these messages with subject Will you consider about RFC 4329?

Try this:

let label : UILable! = String.stringFromHTML("html String")

func stringFromHTML( string: String?) -> String
    {
        do{
            let str = try NSAttributedString(data:string!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true
                )!, options:[NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: NSNumber(unsignedLong: NSUTF8StringEncoding)], documentAttributes: nil)
            return str.string
        } catch
        {
            print("html error\n",error)
        }
        return ""
    }

Hope its helpful.

The GetHashCode function is specifically designed to create a well distributed range of integers with a low probability of collision, so for this use case is likely to be the best you can do.

But, as I'm sure you're aware, hashing 128 bits of information into 32 bits of information throws away a lot of data, so there will almost certainly be collisions if you have a sufficiently large number of GUIDs.

exec sp_msforeachtable 'print ''?'''

Here's a solution I used (it needs #include <time.h>):

int msec = 0, trigger = 10; /* 10ms */
clock_t before = clock();

do {
  /*
   * Do something to busy the CPU just here while you drink a coffee
   * Be sure this code will not take more than `trigger` ms
   */

  clock_t difference = clock() - before;
  msec = difference * 1000 / CLOCKS_PER_SEC;
  iterations++;
} while ( msec < trigger );

printf("Time taken %d seconds %d milliseconds (%d iterations)\n",
  msec/1000, msec%1000, iterations);

At least with Active Directory, I have been able to search by DistinguishedName by doing an LDAP query in this format (assuming that such a record exists with this distinguishedName):

"(distinguishedName=CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com)"

you can use both use array like :

$array = array('tlb_account.crid' =>$value , 'tlb_request.sign'=> 'FALSE' );

and direct assign like:

$this->db->where('tlb_account.crid' =>$value , 'tlb_request.sign'=> 'FALSE');

I wish help you.

One more thing. In my experience this error occurred because there was another error previous to the Function is not defined - uncaught referenceerror.

So, look through the console to see if a previous error exists and if so, correct any that exist. You might be lucky in that they were the problem.

instead of

x <- x[! x %in% c(2,3,5)]

using the packages purrr and magrittr, you can do:

your_vector %<>% discard(~ .x %in% c(2,3,5))

this allows for subsetting using the vector name only once. And you can use it in pipes :)

Objective-C

yourSubView.center = CGPointMake(yourView.frame.size.width  / 2, 
                                 yourView.frame.size.height / 2);

Swift

yourSubView.center = CGPoint(x: yourView.frame.size.width  / 2,
                             y: yourView.frame.size.height / 2)

  String termsOfCondition="<font color=#cc0029>Terms of Use </font>";
  String commma="<font color=#000000>, </font>";
  String privacyPolicy="<font color=#cc0029>Privacy Policy </font>";
  Spanned text=Html.fromHtml("I am of legal age and I have read, understood, agreed and accepted the "+termsOfCondition+commma+privacyPolicy);
        secondCheckBox.setText(text);

Using the Promise pattern:

function getImage(url){
        return new Promise(function(resolve, reject){
            var img = new Image()
            img.onload = function(){
                resolve(url)
            }
            img.onerror = function(){
                reject(url)
            }
            img.src = url
        })
    }

And when calling the function we can handle its response or error quite neatly.

getImage('imgUrl').then(function(successUrl){
    //do stufff
}).catch(function(errorUrl){
    //do stuff
})

The best thing would be to link to the jQuery core is via google.
There are 3 reasons to do it this way,

• Decreased Latency
• Increased parallelism
• Better caching

I have my menu in the site master page. I used the Page_Load() function to make the "Admin" menu item only visible to users with an Admin role.

using System;
using System.Linq;
using Telerik.Web.UI;
using System.Web.Security;



<telerik:RadMenu ID="menu" runat="server" RenderMode="Auto"  >
    <Items>
       <telerik:RadMenuItem    Text="Admin"  Visible="true" />
    </Items>
 </telerik:RadMenu>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        RadMenuItem item = this.menu.FindItemByText("Admin");
        if (null != item)
        {
            if (Roles.IsUserInRole("Admin"))
            {
                item.Visible = true;   
            }
            else
            {
                item.Visible = false;
            }
        }
    }
}

I wouldn't put it in the same <p>, since IMHO the two infos are semantically too different. If you must, I'd suggest this:

<p style="text-align:right">
 <span style="float:left">I'll be on the left</span>
 I'll be on the right
</p>

You can customize the JsonSerializerSettings by using the Formatters.JsonFormatter.SerializerSettings property in the HttpConfiguration object.

For example, you could do that in the Application_Start() method:

protected void Application_Start()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.Formatting =
        Newtonsoft.Json.Formatting.Indented;
}

Thanks to Don Branson,I solve my problem.I think next time i should use this code when i build my repo on server:

root@localhost:~#mkdir foldername
root@localhost:~#cd foldername
root@localhost:~#git init --bare
root@localhost:~#cd ../
root@localhost:~#chown -R usergroup:username foldername

And on client,i user this

$ git remote add origin git@servername:/var/git/foldername
$ git push origin master

You should use the sumif function in Excel:

=SUMIF(A5:C10;"Text_to_find";C5:C10)

This function takes a range like this square A5:C10 then you have some text to find this text can be in A or B then it will add the number from the C-row.

If you're trying to insert in to last_accessed_on, which is a DateTime2, then your issue is with the fact that you are converting it to a varchar in a format that SQL doesn't understand.

If you modify your code to this, it should work, note the format of your date has been changed to: YYYY-MM-DD hh:mm:ss:

UPDATE  student_queues 
SET  Deleted=0, 
     last_accessed_by='raja', 
     last_accessed_on=CONVERT(datetime2,'2014-07-23 09:37:00')
WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

Or if you want to use CAST, replace with:

CAST('2014-07-23 09:37:00.000' AS datetime2)

This is using the SQL ISO Date Format.

just try with sudo. It seems like permission issue!

sudo docker-compose -f docker-compose-deps.yml up -d

it worked for me.

Note

The below answer is not applicable to requests v0.13.0+. The asynchronous functionality was moved to grequests after this question was written. However, you could just replace requests with grequests below and it should work.

I've left this answer as is to reflect the original question which was about using requests < v0.13.0.

To do multiple tasks with async.map asynchronously you have to:

1. Define a function for what you want to do with each object (your task)
2. Add that function as an event hook in your request
3. Call async.map on a list of all the requests / actions

Example:

from requests import async
# If using requests > v0.13.0, use
# from grequests import async

urls = [
    'http://python-requests.org',
    'http://httpbin.org',
    'http://python-guide.org',
    'http://kennethreitz.com'
]

# A simple task to do to each response object
def do_something(response):
    print response.url

# A list to hold our things to do via async
async_list = []

for u in urls:
    # The "hooks = {..." part is where you define what you want to do
    # 
    # Note the lack of parentheses following do_something, this is
    # because the response will be used as the first argument automatically
    action_item = async.get(u, hooks = {'response' : do_something})

    # Add the task to our list of things to do via async
    async_list.append(action_item)

# Do our list of things to do via async
async.map(async_list)

try (FileOutputStream out = new FileOutputStream(filename)) {
    bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
    // PNG is a lossless format, the compression factor (100) is ignored
} catch (IOException e) {
    e.printStackTrace();
}

Try this example:

public void TheDownload(string path)
{
  System.IO.FileInfo toDownload = new System.IO.FileInfo(HttpContext.Current.Server.MapPath(path));

  HttpContext.Current.Response.Clear();
  HttpContext.Current.Response.AddHeader("Content-Disposition",
             "attachment; filename=" + toDownload.Name);
  HttpContext.Current.Response.AddHeader("Content-Length",
             toDownload.Length.ToString());
  HttpContext.Current.Response.ContentType = "application/octet-stream";
  HttpContext.Current.Response.WriteFile(patch);
  HttpContext.Current.Response.End();
} 

The implementation is done in the follows:

TheDownload("@"c:\Temporal\Test.txt"");

Source: http://www.systemdeveloper.info/2014/03/force-downloading-file-from-c.html

public String weekdays[] = new      DateFormatSymbols(Locale.ITALIAN).getWeekdays();
 Calendar c = Calendar.getInstance();
 Date date = new Date();
 c.setTime(date);
 int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
 System.out.println(dayOfWeek);
 System.out.println(weekdays[dayOfWeek]);

If you want to return a date type as just a date use

CONVERT(date, SYSDATETIME())

or

SELECT CONVERT(date,SYSDATETIME()) 

or

DECLARE @DateOnly Datetime
SET @DateOnly=CONVERT(date,SYSDATETIME())

This is set background color on even and odd li:

  li:nth-child(odd) { background: #ffffff; }
  li:nth-child(even) { background: #80808030; }

You are trying to remove value from list in advanced "for loop", which is not possible, even if you apply any trick (which you did in your code). Better way is to code iterator level as other advised here.

I wonder how people have not suggested traditional for loop approach.

for( int i = 0; i < lStringList.size(); i++ )
{
    String lValue = lStringList.get( i );
    if(lValue.equals("_Not_Required"))
    {
         lStringList.remove(lValue);
         i--; 
    }  
}

This works as well.

Generics only support object types, not primitives. Unlike C++ templates, generics don't involve code generatation and there is only one HashMap code regardless of the number of generic types of it you use.

Trove4J gets around this by pre-generating selected collections to use primitives and supports TCharIntHashMap which to can wrap to support the Map<Character, Integer> if you need to.

TCharIntHashMap: An open addressed Map implementation for char keys and int values.

This is what I do for those situations:

I don't start the html element with class 'hide', but I put style="display: none".

This is because bootstrap jquery modifies the style attribute and not the classes to hide/unhide.

Example:

<button type="button" id="btn_cancel" class="btn default" style="display: none">Cancel</button>

or

<button type="button" id="btn_cancel" class="btn default display-hide">Cancel</button>

Later on, you can run all the following that will work:

$('#btn_cancel').toggle() // toggle between hide/unhide
$('#btn_cancel').hide()
$('#btn_cancel').show()

You can also uso the class of Twitter Bootstrap 'display-hide', which also works with the jQuery IU .toggle() method.

You can even use this one. worked well for me

$("#registerform").attr("action", "register.php?btnsubmit=Save") 
$('#registerform').submit();

this will submit btnsubmit =Save as GET value to register.php form.

You should check for (args == null || args.length == 0). Although the null check isn't really needed, it is a good practice.

Want to align an image which have after a text / title and both are inside a div?

See on JSfiddle or Run Code Snippet.

Just be sure to have an ID or a class at all your elements (div, img, title, etc.).

For me works this solution on all browsers (for mobile devices you must to adapt your code with: @media).

    color: red;_x000D_
    font-size: 14px;_x000D_
}_x000D_
.mydivclass {_x000D_
    margin-top: 30px;_x000D_
    display: block;_x000D_
}_x000D_
img.mydesiredclass {_x000D_
    margin-right: 10px;_x000D_
    display: block;_x000D_
    float: left; /* If you want to allign the text with an image on the same row */_x000D_
    width: 100px;_x000D_
    heght: 100px;_x000D_
    margin-top: -40px /* Change this value to adapt to your page */;_x000D_
}

In pycharm 2019.2, you can simply do this to run all tests:

1. Run > Edit Configurations > Add pytest
2. Set options as shown in following screenshot
3. Click on Debug (or run pytest using e.g. hotkeys Shift+Alt+F9)

The common wisdom that floating-point numbers cannot be compared for equality is inaccurate. Floating-point numbers are no different from integers: If you evaluate "a == b", you will get true if they are identical numbers and false otherwise (with the understanding that two NaNs are of course not identical numbers).

The actual problem is this: If I have done some calculations and am not sure the two numbers I have to compare are exactly correct, then what? This problem is the same for floating-point as it is for integers. If you evaluate the integer expression "7/3*3", it will not compare equal to "7*3/3".

So suppose we asked "How do I compare integers for equality?" in such a situation. There is no single answer; what you should do depends on the specific situation, notably what sort of errors you have and what you want to achieve.

Here are some possible choices.

If you want to get a "true" result if the mathematically exact numbers would be equal, then you might try to use the properties of the calculations you perform to prove that you get the same errors in the two numbers. If that is feasible, and you compare two numbers that result from expressions that would give equal numbers if computed exactly, then you will get "true" from the comparison. Another approach is that you might analyze the properties of the calculations and prove that the error never exceeds a certain amount, perhaps an absolute amount or an amount relative to one of the inputs or one of the outputs. In that case, you can ask whether the two calculated numbers differ by at most that amount, and return "true" if they are within the interval. If you cannot prove an error bound, you might guess and hope for the best. One way of guessing is to evaluate many random samples and see what sort of distribution you get in the results.

Of course, since we only set the requirement that you get "true" if the mathematically exact results are equal, we left open the possibility that you get "true" even if they are unequal. (In fact, we can satisfy the requirement by always returning "true". This makes the calculation simple but is generally undesirable, so I will discuss improving the situation below.)

If you want to get a "false" result if the mathematically exact numbers would be unequal, you need to prove that your evaluation of the numbers yields different numbers if the mathematically exact numbers would be unequal. This may be impossible for practical purposes in many common situations. So let us consider an alternative.

A useful requirement might be that we get a "false" result if the mathematically exact numbers differ by more than a certain amount. For example, perhaps we are going to calculate where a ball thrown in a computer game traveled, and we want to know whether it struck a bat. In this case, we certainly want to get "true" if the ball strikes the bat, and we want to get "false" if the ball is far from the bat, and we can accept an incorrect "true" answer if the ball in a mathematically exact simulation missed the bat but is within a millimeter of hitting the bat. In that case, we need to prove (or guess/estimate) that our calculation of the ball's position and the bat's position have a combined error of at most one millimeter (for all positions of interest). This would allow us to always return "false" if the ball and bat are more than a millimeter apart, to return "true" if they touch, and to return "true" if they are close enough to be acceptable.

So, how you decide what to return when comparing floating-point numbers depends very much on your specific situation.

As to how you go about proving error bounds for calculations, that can be a complicated subject. Any floating-point implementation using the IEEE 754 standard in round-to-nearest mode returns the floating-point number nearest to the exact result for any basic operation (notably multiplication, division, addition, subtraction, square root). (In case of tie, round so the low bit is even.) (Be particularly careful about square root and division; your language implementation might use methods that do not conform to IEEE 754 for those.) Because of this requirement, we know the error in a single result is at most 1/2 of the value of the least significant bit. (If it were more, the rounding would have gone to a different number that is within 1/2 the value.)

Going on from there gets substantially more complicated; the next step is performing an operation where one of the inputs already has some error. For simple expressions, these errors can be followed through the calculations to reach a bound on the final error. In practice, this is only done in a few situations, such as working on a high-quality mathematics library. And, of course, you need precise control over exactly which operations are performed. High-level languages often give the compiler a lot of slack, so you might not know in which order operations are performed.

There is much more that could be (and is) written about this topic, but I have to stop there. In summary, the answer is: There is no library routine for this comparison because there is no single solution that fits most needs that is worth putting into a library routine. (If comparing with a relative or absolute error interval suffices for you, you can do it simply without a library routine.)

Besides that your indention is wrong. The code wont work. I know you are using python 3. something. I am using python 2.7.3 the code that will actually work for what you trying accomplish is this.

number = str(23)
guess =  input('Enter a number: ')
if guess == number:
   print('Congratulations! You guessed it.')
elif guess < number:
     print('Wrong Number')
elif guess < number:
     print("Wrong Number')

The only difference I would tell python that number is a string of character for the code to work. If not is going to think is a Integer. When somebody runs the code they are inputing a string not an integer. There are many ways of changing this code but this is the easy solution I wanted to provide there is another way that I cant think of without making the 23 into a string. Or you could of "23" put quotations or you could of use int() function in the input. that would transform anything they input into and integer a number.

Turns out I have not looked good enough at my stack trace, the problem is not that the external JAR is not included.

The problem is that Android platform is missing javax.naming.* and many other packages that the external JAR has dependencies too.

Adding external JAR files, and setting Order and Export in Eclipse works as expected with Android projects.

showInventory(player);     // I get the error here.

void showInventory(player& obj) {   // By Johnny :D

this means that player is an datatype and showInventory expect an referance to an variable of type player.

so the correct code will be

  void showInventory(player& obj) {   // By Johnny :D
    for(int i = 0; i < 20; i++) {
        std::cout << "\nINVENTORY:\n" + obj.getItem(i);
        i++;
        std::cout << "\t\t\t" + obj.getItem(i) + "\n";
        i++;
    }
    }

players myPlayers[10];

    std::string toDo() //BY KEATON
    {
    std::string commands[5] =   // This is the valid list of commands.
        {"help", "inv"};

    std::string ans;
    std::cout << "\nWhat do you wish to do?\n>> ";
    std::cin >> ans;

    if(ans == commands[0]) {
        helpMenu();
        return NULL;
    }
    else if(ans == commands[1]) {
        showInventory(myPlayers[0]);     // or any other index,also is not necessary to have an array
        return NULL;
    }

}

With the help of the given links I was able to solve the problem myself. The correct way is to get the resource ID with

getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
                             "raw", getPackageName());

To get it as a InputStream

InputStream ins = getResources().openRawResource(
            getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
            "raw", getPackageName()));

I didn't find an easy way to add a new key pair via the console, but you can do it manually.

Just ssh into your EC2 box with the existing key pair. Then edit the ~/.ssh/authorized_keys and add the new key on a new line. Exit and ssh via the new machine. Success!

Graphviz - from the web page:

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in several useful formats such as images and SVG for web pages, Postscript for inclusion in PDF or other documents; or display in an interactive graph browser. (Graphviz also supports GXL, an XML dialect.)

It's the simplest and most productive tool I've found to create a variety of boxes-and-lines diagrams. I have and use Visio and OmniGraffle, but there's always the temptation to make "just one more adjustment".

It's also quite easy to write code to produce the "dot file" format that Graphiz consumes, so automated diagram production is also nicely within reach.

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

Use this:

0?[1-9]|1[012]

• 07: valid
• 7: valid
• 0: not match
• 00 : not match
• 13 : not match
• 21 : not match

To test a pattern as 07/2018 use this:

/^(0?[1-9]|1[012])\/([2-9][0-9]{3})$/

(Date range between 01/2000 to 12/9999 )

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

Use comma separated values as below.

$email_to = 'Mary <[email protected]>, Kelly <[email protected]>';
@mail($email_to, $email_subject, $email_message, $headers);

or run a foreach for email address

//list of emails in array format and each one will see their own to email address
$arrEmail = array('Mary <[email protected]>', 'Kelly <[email protected]>');

foreach($arrEmail as $key => $email_to)
    @mail($email_to, $email_subject, $email_message, $headers);

as @rampion mentioned, if you are in clang gcc, the warnings are by name, not number, and you'll need to do:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunused-variable"
// ..your code..
#pragma clang diagnostic pop

How it should be done in the tidyverse:

df.dplyr.purrr <- listOfDataFrames %>% map_df(bind_rows)

Concatenation of words in the package name is something most developers don't do.

You can use something like.

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine
