Programs & Examples On #Auto indent

Here is how you to do it automatically on save: https://coderwall.com/p/zvyg7a/convert-tabs-to-spaces-on-file-save

Unfortunately the package is not working when you install it from the Package Manager.

Ctrl+Shift+F formats the selected line(s) or the whole source code if you haven't selected any line(s) as per the formatter specified in your Eclipse, while Ctrl+I gives proper indent to the selected line(s) or the current line if you haven't selected any line(s).

This is the best help that I found:

https://atom.io/packages/atom-beautify

This package can be installed in Atom and then CTRL+ALT+B solve the problem.

I wrote a plugin for it. You can find it here or look for "ReIndent" in package control. It mostly does the same thing as Kyle Finley wrote but in a convenient way with shortcuts for converting between 2 and 4 and vice-versa.

The shortcut key is ctrl+] to indentation and ctrl +[ to unindent

Update: Better answer here: https://stackoverflow.com/a/38258720/62202

To turn off autoindent when you paste code, there's a special "paste" mode.

Type

:set paste

Then paste your code. Note that the text in the tooltip now says -- INSERT (paste) --.

After you pasted your code, turn off the paste-mode, so that auto-indenting when you type works correctly again.

:set nopaste

However, I always found that cumbersome. That's why I map <F3> such that it can switch between paste and nopaste modes while editing the text! I add this to .vimrc

set pastetoggle=<F3>

I'm using Notepad 7.6 with "Plugin Admin" and I could not find XML Tools.
I had to install it manually like @some-java-guy did in his answer except that my plugins folder was located here: C:\Users\<my username>\AppData\Local\Notepad++\plugins
In that directory I created a new directory (named XmlTools) and copied XMLTools.dll there. (And I copied all dependencies to the Notepad++ directory in Program files.)

Related, if you open a file that uses both tabs and spaces, assuming you've got

set expandtab ts=4 sw=4 ai

You can replace all the tabs with spaces in the entire file with

:%retab

Using a list comprehension:

from datetime import date, timedelta

d1 = date(2008,8,15)
d2 = date(2008,9,15)

# this will give you a list containing all of the dates
dd = [d1 + timedelta(days=x) for x in range((d2-d1).days + 1)]

for d in dd:
    print d

# you can't join dates, so if you want to use join, you need to
# cast to a string in the list comprehension:
ddd = [str(d1 + timedelta(days=x)) for x in range((d2-d1).days + 1)]
# now you can join
print "\n".join(ddd)

There is a limit to the total size of all columns inlined into the index definition. That said though, I have never had to create index that wide. To me, the bigger advantage is the fact that you can cover more queries with one index that has included columns as they don't have to be defined in any particular order. Think about is as an index within the index. One example would be the StoreID (where StoreID is low selectivity meaning that each store is associated with a lot of customers) and then customer demographics data (LastName, FirstName, DOB): If you just inline those columns in this order (StoreID, LastName, FirstName, DOB), you can only efficiently search for customers for which you know StoreID and LastName.

On the other hand, defining the index on StoreID and including LastName, FirstName, DOB columns would let you in essence do two seeks- index predicate on StoreID and then seek predicate on any of the included columns. This would let you cover all possible search permutationsas as long as it starts with StoreID.

FYI this turned out to be an issue for me where I had two tables in a statement like the following:

SELECT * FROM table1
UNION ALL
SELECT * FROM table2

It worked, but then somewhere along the line the order of columns in one of the table definitions got changed. Changing the * to SELECT column1, column2 fixed the issue. No idea how that happened, but lesson learned!

Use tweet web intent, this is the simple link:

https://twitter.com/intent/tweet?url=<?=urlencode($url)?>

more variables at https://dev.twitter.com/web/tweet-button/web-intent

one more suggestion :

unsigned int a = 0xABCDEF23;
a = ((a&(0x0000FFFF)) << 16) | ((a&(0xFFFF0000)) >> 16);
a = ((a&(0x00FF00FF)) << 8) | ((a&(0xFF00FF00)) >>8);
printf("%0x\n",a);

Change your TableView Style:

self.tableview = [[UITableView alloc] initwithFrame:frame style:UITableViewStyleGrouped];

As per apple documentation for UITableView:

UITableViewStylePlain- A plain table view. Any section headers or footers are displayed as inline separators and float when the table view is scrolled.

UITableViewStyleGrouped- A table view whose sections present distinct groups of rows. The section headers and footers do not float.

Hope this small change will help you ..

What you have should work. It depends on the type of data you are setting i.e. if it's a string value you need to make sure it's in quotes e.g.

var val = '@ViewBag.ForSection';

If it's an integer you need to parse it as one i.e.

var val = parseInt(@ViewBag.ForSection);

You can use this keyword to access custom data, passed to $.ajax() function:

    $.ajax({
        // ... // --> put ajax configuration parameters here
        yourCustomData: {param1: 'any value', time: '1h24'},  // put your custom key/value pair here
        success: successHandler
    });

    function successHandler(data, textStatus, jqXHR) {
        alert(this.yourCustomData.param1);  // shows "any value"
        console.log(this.yourCustomData.time);
    }

From the notebook menu you can save the file directly as a python script. Go to the 'File' option of the menu, then select 'Download as' and there you would see a 'Python (.py)' option.

Another option would be to use nbconvert from the command line:

jupyter nbconvert --to script 'my-notebook.ipynb'

Have a look here.

As drew_w said, you can find a good example here.

JSFIDDLE

By reading the javadoc in java8, you can find the following at the declaration of interface Override:

If a method is annotated with this annotation type compilers are required to generate an error message unless at least one of the following conditions hold:

• The method does override or implement a method declared in a supertype.
• The method has a signature that is override-equivalent to that of any public method declared in {@linkplain Object}.

So, at least in java8, you should use @Override on an implementation of an interface method.

If you are using Twig in your application as a component you can do this:

$twig = new Twig_Environment($loader, array(
    'autoescape' => false
));

$twig->addFilter('var_dump', new Twig_Filter_Function('var_dump'));

Then in your templates:

{{ my_variable | var_dump }}

You can use Inkscape on the commandline only, without opening a GUI. Try this:

inkscape \
  --without-gui \
  --file=input.pdf \
  --export-plain-svg=output.svg 

For a complete list of all commandline options, run inkscape --help.

You are missing an include : #include <stdlib.h>, so GCC creates an implicit declaration of atof and atod, leading to garbage values.

And the format specifier for double is %f, not %d (that is for integers).

#include <stdlib.h>
#include <stdio.h>

int main()
{
  char *test = "12.11";
  double temp = strtod(test,NULL);
  float ftemp = atof(test);
  printf("price: %f, %f",temp,ftemp);
  return 0;
}
/* Output */
price: 12.110000, 12.110000

The real problem is that the default owner(dbo) doesn't have a login mapped to it at all.As I tried to map the sa login to the database owner I received another error stating "User,group, or role 'dbo' already exists...".However if you try this code it will actually works :

EXEC sp_dbcmptlevel 'yourDB', '90';

go

ALTER AUTHORIZATION ON DATABASE::yourDB TO "yourLogin"

go

use [yourDB]

go

EXECUTE AS USER = N'dbo' REVERT

go

There's better support for this now through conda-env. You can, for example, now do:

name: sample_env
channels:
dependencies:
   - requests
   - bokeh>=0.10.0
   - pip:
     - "--editable=git+https://github.com/pythonforfacebook/facebook-sdk.git@8c0d34291aaafec00e02eaa71cc2a242790a0fcc#egg=facebook_sdk-master"

It's still calling pip under the covers, but you can now unify your conda and pip package specifications in a single environment.yml file.

If you wanted to update your root environment with this file, you would need to save this to a file (for example, environment.yml), then run the command: conda env update -f environment.yml.

It's more likely that you would want to create a new environment:

conda env create -f environment.yml (changed as supposed in the comments)

OpenCode appears to be a project at the MIT Media Lab for running Java Code online in a web browser interface. Years ago, I played around a lot at TopCoder. It runs a Java Web Start app, though, so you would need a Java run time installed.

You could use this:

data[:1] = ['hello']

In India we are using http://www.itrafficnews.com. But the data is posted by the users. I dont think google will provide the data.

[k for k,v in l if v =='delicia']

here l is the list of tuples-[(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")]

And instead of converting it to a dict, we are using llist comprehension.

*Key* in Key,Value in list, where value = **delicia**

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

You can use the grid feature for the second unused axis x2, which is the most natural way of drawing a set of regular spaced lines.

set grid x2tics
set x2tics 10 format "" scale 0

In general, the grid is drawn at the same position as the tics on the axis. In case the position of the lines does not correspond to the tics position, gnuplot provides an additional set of tics, called x2tics. format "" and scale 0 hides the x2tics so you only see the grid lines.

You can style the lines as usual with linewith, linecolor.

overflow: auto (or overflow-y: auto) is the correct way to go.

The problem is that your text area is taller than your div. The div ends up cutting off the textbox, so even though it looks like it should start scrolling when the text is taller than 159px it won't start scrolling until the text is taller than 400px which is the height of the textbox.

Try this: http://jsfiddle.net/G9rfq/1/

I set overflow:auto on the text box, and made the textbox the same size as the div.

Also I don't believe it's valid to have a div inside a label, the browser will render it, but it might cause some funky stuff to happen. Also your div isn't closed.

First you should know, how much memory is allocated when you define and allocate memory in below case.

   typedef struct person{
       char firstName[100], surName[51]
  } PERSON;
  PERSON *testPerson = (PERSON*) malloc(sizeof(PERSON));

1) The sizeof(PERSON) now returns 151 bytes (Doesn't include padding)

2) The memory of 151 bytes is allocated in heap.

3) To free, call free(testPerson).

but If you declare your structure as

  typedef struct person{
      char *firstName, *surName;
  } PERSON;
  PERSON *testPerson = (PERSON*) malloc(sizeof(PERSON));

then

1) The sizeof(PERSON) now returns 8 bytes (Doesn't include padding)

2) Need to allocate memory for firstName and surName by calling malloc() or calloc(). like

        testPerson->firstName = (char *)malloc(100);

3) To free, first free the members in the struct than free the struct. i.e, free(testPerson->firstName); free(testPerson->surName); free(testPerson);

document.documentMode is undefined if the browser is not IE8,

it returns 8 for standards mode and 7 for 'compatable to IE7'

If it is running as IE7 there are a lot of css and dom features that won't be supported.

In a private project a wrote this filter

angular.module('myApp')
    .filter('isEmpty', function () {
        var bar;
        return function (obj) {
            for (bar in obj) {
                if (obj.hasOwnProperty(bar)) {
                    return false;
                }
            }
            return true;
        };
    });

usage:

<p ng-hide="items | isEmpty">Some Content</p>

testing:

describe('Filter: isEmpty', function () {

    // load the filter's module
    beforeEach(module('myApp'));

    // initialize a new instance of the filter before each test
    var isEmpty;
    beforeEach(inject(function ($filter) {
        isEmpty = $filter('isEmpty');
    }));

    it('should return the input prefixed with "isEmpty filter:"', function () {
          expect(isEmpty({})).toBe(true);
          expect(isEmpty({foo: "bar"})).toBe(false);
    });

});

regards.

I use another approach.

Just try to find all a where id starts from some substring.

JS

$('a[id^=v-photos-tab]').click(function () {
     alert("Handler for .click() called.");
});

HTML

<a class="nav-item nav-link active show"  id="v-photos-tab-3a623245-7dc7-4a22-90d0-62705ad0c62b" data-toggle="pill" href="#v-photos-3a623245-7dc7-4a22-90d0-62705ad0c62b" role="tab" aria-controls="v-requestbase-photos" aria-selected="true"><span>Cool photos</span></a>

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

I hope this'll do . or else, may ask me directly

Sub RemoveBlankLines()
    Application.ScreenUpdating = False
    Dim rngCel As Range
    Dim strOldVal As String
    Dim strNewVal As String

    For Each rngCel In Selection
        If rngCel.HasFormula = False Then
            strOldVal = rngCel.Value
            strNewVal = strOldVal
            Debug.Print rngCel.Address

            Do
            If Left(strNewVal, 1) = vbLf Then strNewVal = Right(strNewVal, Len(strNewVal) - 1)

        rngCel.Value = Application.Trim(rngCel.Value)
        End If
    Next rngCel
    Application.ScreenUpdating = True
End Sub

to print the current user who is using the database

select user();

or

select current_user();

In general the best way is to Change the table collation. However I have an old application and are not really able to estimate the outcome whether this has side effects. Therefore I tried somehow to convert the string into some other format that solved the collation problem. What I found working is to do the string compare by converting the strings into a hexadecimal representation of it's characters. On the database this is done with HEX(column). For PHP you may use this function:

public static function strToHex($string)
{
    $hex = '';
    for ($i=0; $i<strlen($string); $i++){
        $ord = ord($string[$i]);
        $hexCode = dechex($ord);
        $hex .= substr('0'.$hexCode, -2);
    }
    return strToUpper($hex);
}

When doing the database query, your original UTF8 string must be converted first into an iso string (e.g. using utf8_decode() in PHP) before using it in the DB. Because of the collation type the database cannot have UTF8 characters inside so the comparism should work event though this changes the original string (converting UTF8 characters that are not existend in the ISO charset result in a ? or these are removed entirely). Just make sure that when you write data into the database, that you use the same UTF8 to ISO conversion.

It's better to Use feature in html5 5 data Attributes

<script src="http://path.to/widget.js" data-width="200" data-height="200">
</script>

Inside the script file http://path.to/widget.js you can get the paremeters in that way:

<script>
function getSyncScriptParams() {
         var scripts = document.getElementsByTagName('script');
         var lastScript = scripts[scripts.length-1];
         var scriptName = lastScript;
         return {
             width : scriptName.getAttribute('data-width'),
             height : scriptName.getAttribute('data-height')
         };
 }
</script>

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

http://jsfiddle.net/5b2eb/

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

http://jsfiddle.net/5b2eb/1/

It only safer as long as you don't build with -Wno-narrowing like say Google does in Chromium. If you do, then it is LESS safe. Without that flag the only unsafe cases will be fixed by C++20 though.

Note: A) Curly brackets are safer because they don't allow narrowing. B) Curly brackers are less safe because they can bypass private or deleted constructors, and call explicit marked constructors implicitly.

Those two combined means they are safer if what is inside is primitive constants, but less safe if they are objects (though fixed in C++20)

var myProp = 'prop';
if(myObj.hasOwnProperty(myProp)){
    alert("yes, i have that property");
}

Or

var myProp = 'prop';
if(myProp in myObj){
    alert("yes, i have that property");
}

Or

if('prop' in myObj){
    alert("yes, i have that property");
}

Note that hasOwnProperty doesn't check for inherited properties, whereas in does. For example 'constructor' in myObj is true, but myObj.hasOwnProperty('constructor') is not.

I have faced the same problem once too. I have solved it by creating on empty link with a ref to it like so:

linkRef = React.createRef();
render() {
    return (
        <a ref={this.linkRef}/>
    );
}

and in my fetch function i have done something like this:

fetch(/*your params*/)
    }).then(res => {
        return res.blob();
    }).then(blob => {
        const href = window.URL.createObjectURL(blob);
        const a = this.linkRef.current;
        a.download = 'Lebenslauf.pdf';
        a.href = href;
        a.click();
        a.href = '';
    }).catch(err => console.error(err));

basically i have assigned the blobs url(href) to the link, set the download attribute and enforce one click on the link. As far as i understand this is the "basic" idea of the answer provided by @Nate. I dont know if this is a good idea to do it this way... I did.

With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the

application.properties

spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass

spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true

Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your own SQL's like JPQL.

@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}

And if you still need to use the Entity Manager you can create another class.

public class ObjectRepositoryImpl implements ObjectCustomMethods{

    @PersistenceContext
    private EntityManager em;

}

This should be in your pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.5.RELEASE</version>

The error message explains it pretty well:

ValueError: The truth value of an array with more than one element is ambiguous. 
Use a.any() or a.all()

What should bool(np.array([False, False, True])) return? You can make several plausible arguments:

(1) True, because bool(np.array(x)) should return the same as bool(list(x)), and non-empty lists are truelike;

(2) True, because at least one element is True;

(3) False, because not all elements are True;

and that's not even considering the complexity of the N-d case.

So, since "the truth value of an array with more than one element is ambiguous", you should use .any() or .all(), for example:

>>> v = np.array([1,2,3]) == np.array([1,2,4])
>>> v
array([ True,  True, False], dtype=bool)
>>> v.any()
True
>>> v.all()
False

and you might want to consider np.allclose if you're comparing arrays of floats:

>>> np.allclose(np.array([1,2,3+1e-8]), np.array([1,2,3]))
True

letter = ["a", "b", "c", "d"]
letter.extend(["e", "f", "g", "h"])
letter.extend(("e", "f", "g", "h"))
print(letter)
... 
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'e', 'f', 'g', 'h']
    

You can't put a pseudo element in an input element, but can put in shadow element, like a placeholder!

input[type="text"] {   
  &::-webkit-input-placeholder {
    &:before {
      // your code
    }
  }
}

To make it work in other browsers, use :-moz-placeholder, ::-moz-placeholder and :-ms-input-placeholder in different selectors. Can't group the selectors, because if a browser doesn't recognize the selector invalidates the entire statement.

UPDATE: The above code works only with CSS pre-processor (SASS, LESS...), without pre-processors use:

input[type="text"]::-webkit-input-placeholder:before { // your code }

let res = /^[a-zA-Z]+$/.test('sfjd');
console.log(res);

Note: If you have any punctuation marks or anything, those are all invalid too. Dashes and underscores are invalid. \w covers a-zA-Z and some other word characters. It all depends on what you need specifically.

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)

Params contains the following three groups of parameters:

1. User supplied parameters
   • GET (http://domain.com/url?param1=value1&param2=value2 will set params[:param1] and params[:param2])
   • POST (e.g. JSON, XML will automatically be parsed and stored in params)
   • Note: By default, Rails duplicates the user supplied parameters and stores them in params[:user] if in UsersController, can be changed with wrap_parameters setting
2. Routing parameters
   • match '/user/:id' in routes.rb will set params[:id]
3. Default parameters
   • params[:controller] and params[:action] is always available and contains the current controller and action

For information
if anyone use

$('#formId').submit();

Do not something like this

<button name = "submit">

It took many hours to find me that submit() won't work like this.

Here's a concise answer that determines the unit automatically.

public static string ToBytesCount(this long bytes)
{
    int unit = 1024;
    string unitStr = "b";
    if (bytes < unit) return string.Format("{0} {1}", bytes, unitStr);
    else unitStr = unitStr.ToUpper();
    int exp = (int)(Math.Log(bytes) / Math.Log(unit));
    return string.Format("{0:##.##} {1}{2}", bytes / Math.Pow(unit, exp), "KMGTPEZY"[exp - 1], unitStr);
}

"b" is for bit, "B" is for Byte and "KMGTPEZY" are respectively for kilo, mega, giga, tera, peta, exa, zetta and yotta

One can expand it to take ISO/IEC80000 into account:

public static string ToBytesCount(this long bytes, bool isISO = true)
{
    int unit = 1024;
    string unitStr = "b";
    if (!isISO) unit = 1000;
    if (bytes < unit) return string.Format("{0} {1}", bytes, unitStr);
    else unitStr = unitStr.ToUpper();
    if (isISO) unitStr = "i" + unitStr;
    int exp = (int)(Math.Log(bytes) / Math.Log(unit));
    return string.Format("{0:##.##} {1}{2}", bytes / Math.Pow(unit, exp), "KMGTPEZY"[exp - 1], unitStr);
}

This is a message for me in the future:

Just use: (unsigned)!((int)0)

It creates the largest possible number in any machine by assigning all bits to 1s (ones) and then casts it to unsigned

Even better

#define INF (unsigned)!((int)0)

And then just use INF in your code

I had the Cannot edit in read-only editor error when trying to edit code after stopping the debug mode (for 2-3 minutes after pressing Shift+F5).

Turns out the default Node version (v9.11.1) wasn't exiting gracefully, leaving VScode stuck on read-only.
Simply adding "runtimeVersion": "12.4.0" to my launch.json file fixed it.

alternatively, change your default Node version to the latest stable version (you can see the current version on the DEBUG CONSOLE when starting debug mode).

if you getting this type of error so I suggest you used to stored proc data as usual list then binding the other controls because I also get this error so I solved it like this ex:-

repeater.DataSource = data.SPBinsReport().Tolist();
repeater.DataBind();

try like this

in my case, I got the same exception because the user that I configured in the app did not existed in the DB, creating the user and granting needed permissions solved the problem.

$id = intval($_GET['id']);
$sql = "SELECT * FROM student WHERE IDNO=$id";
$result = mysql_query($sql) or trigger_error(mysql_error().$sql);

always do it this way and it will tell you what is wrong

Add these two like of code work like a charm for any view like Button, Linear Layout, or CardView Just put these two lines and see the magic...

android:foreground="?android:attr/selectableItemBackground"
android:clickable="true"

If you are calling a RESTful service from a Service Provider (e.g Facebook, Twitter), you can do it with any flavour of your choice:

If you don't want to use external libraries, you can use java.net.HttpURLConnection or javax.net.ssl.HttpsURLConnection (for SSL), but that is call encapsulated in a Factory type pattern in java.net.URLConnection. To receive the result, you will have to connection.getInputStream() which returns you an InputStream. You will then have to convert your input stream to string and parse the string into it's representative object (e.g. XML, JSON, etc).

Alternatively, Apache HttpClient (version 4 is the latest). It's more stable and robust than java's default URLConnection and it supports most (if not all) HTTP protocol (as well as it can be set to Strict mode). Your response will still be in InputStream and you can use it as mentioned above.

Documentation on HttpClient: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/index.html

To get rid of the outline when clicking, add outline:none

jsFiddle example

button {
    background-color: Transparent;
    background-repeat:no-repeat;
    border: none;
    cursor:pointer;
    overflow: hidden;
    outline:none;
}

button {_x000D_
    background-color: Transparent;_x000D_
    background-repeat:no-repeat;_x000D_
    border: none;_x000D_
    cursor:pointer;_x000D_
    overflow: hidden;_x000D_
    outline:none;_x000D_
}

<button>button</button>

Here is a portable shell function that should work in ANY Bourne comparable shell. It will resolve the relative path punctuation ".. or ." and dereference symbolic links.

If for some reason you do not have a realpath(1) command, or readlink(1) this can be aliased.

which realpath || alias realpath='real_path'

Enjoy:

real_path () {
  OIFS=$IFS
  IFS='/'
  for I in $1
  do
    # Resolve relative path punctuation.
    if [ "$I" = "." ] || [ -z "$I" ]
      then continue
    elif [ "$I" = ".." ]
      then FOO="${FOO%%/${FOO##*/}}"
           continue
      else FOO="${FOO}/${I}"
    fi

    ## Resolve symbolic links
    if [ -h "$FOO" ]
    then
    IFS=$OIFS
    set `ls -l "$FOO"`
    while shift ;
    do
      if [ "$1" = "->" ]
        then FOO=$2
             shift $#
             break
      fi
    done
    IFS='/'
    fi
  done
  IFS=$OIFS
  echo "$FOO"
}

also, just in case anybody is interested here is how to implement basename and dirname in 100% pure shell code:

## http://www.opengroup.org/onlinepubs/000095399/functions/dirname.html
# the dir name excludes the least portion behind the last slash.
dir_name () {
  echo "${1%/*}"
}

## http://www.opengroup.org/onlinepubs/000095399/functions/basename.html
# the base name excludes the greatest portion in front of the last slash.
base_name () {
  echo "${1##*/}"
}

• In your app.component.html use:

    [ngStyle]="{'background-color':backcolor}"
  

• In app.ts declare variable of string type backcolor:string.

• Set the variable this.backcolor="red".

I was facing the same issue earlier but I have somehow found the solution, You can try reg.predict([[3300]]).

The API used to allow scalar value but now you need to give a 2D array.

If you are using python 3 or above,

>>> list(bytes(b'test'))
[116, 101, 115, 116]

A @ViewScoped bean lives exactly as long as a JSF view. It usually starts with a fresh new GET request, or with a navigation action, and will then live as long as the enduser submits any POST form in the view to an action method which returns null or void (and thus navigates back to the same view). Once you refresh the page, or return a non-null string (even an empty string!) navigation outcome, then the view scope will end.

A @RequestScoped bean lives exactly as long a HTTP request. It will thus be garbaged by end of every request and recreated on every new request, hereby losing all changed properties.

A @ViewScoped bean is thus particularly more useful in rich Ajax-enabled views which needs to remember the (changed) view state across Ajax requests. A @RequestScoped one would be recreated on every Ajax request and thus fail to remember all changed view state. Note that a @ViewScoped bean does not share any data among different browser tabs/windows in the same session like as a @SessionScoped bean. Every view has its own unique @ViewScoped bean.

import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

The re.sub function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>') and replacing them with nothing ('').

The ? is used in re for non-greedy searches.

More about the re module.

@Sparr is right, but I guess you expected byte array like byte[] in C#. It's the same solution as Sparr did but instead of HEX you expected int presentation (range from 0 to 255) of each char. You can do as follows:

$byte_array = unpack('C*', 'The quick fox jumped over the lazy brown dog');
var_dump($byte_array);  // $byte_array should be int[] which can be converted
                        // to byte[] in C# since values are range of 0 - 255

By using var_dump you can see that elements are int (not string).

   array(44) {  [1]=>  int(84)  [2]=>  int(104) [3]=>  int(101) [4]=>  int(32)
[5]=> int(113)  [6]=>  int(117) [7]=>  int(105) [8]=>  int(99)  [9]=>  int(107)
[10]=> int(32)  [11]=> int(102) [12]=> int(111) [13]=> int(120) [14]=> int(32)
[15]=> int(106) [16]=> int(117) [17]=> int(109) [18]=> int(112) [19]=> int(101)
[20]=> int(100) [21]=> int(32)  [22]=> int(111) [23]=> int(118) [24]=> int(101)
[25]=> int(114) [26]=> int(32)  [27]=> int(116) [28]=> int(104) [29]=> int(101)
[30]=> int(32)  [31]=> int(108) [32]=> int(97)  [33]=> int(122) [34]=> int(121)
[35]=> int(32)  [36]=> int(98)  [37]=> int(114) [38]=> int(111) [39]=> int(119)
[40]=> int(110) [41]=> int(32)  [42]=> int(100) [43]=> int(111) [44]=> int(103) }

Be careful: the output array is of 1-based index (as it was pointed out in the comment)

These are the primitive types in Java:

• boolean
• byte
• short
• char
• int
• long
• float
• double

All the other types are reference types: they reference objects.

This is the first part of the Java tutorial about the basics of the language.

Iterate through strings characters and use functions of 'Char' called 'IsLetter' and 'IsDigit'.

If you need something more specific - use Regex class.

The only time the second insert into @clases should fail to fire is if an error occurred in the first insert statement.

If that's the case, then you need to decide if the second statement should run prior to the first OR if you need a transaction in order to perform a rollback.

$lookup (aggregation)

Performs a left outer join to an unsharded collection in the same database to filter in documents from the “joined” collection for processing. To each input document, the $lookup stage adds a new array field whose elements are the matching documents from the “joined” collection. The $lookup stage passes these reshaped documents to the next stage. The $lookup stage has the following syntaxes:

Equality Match

To perform an equality match between a field from the input documents with a field from the documents of the “joined” collection, the $lookup stage has the following syntax:

{
   $lookup:
     {
       from: <collection to join>,
       localField: <field from the input documents>,
       foreignField: <field from the documents of the "from" collection>,
       as: <output array field>
     }
}

The operation would correspond to the following pseudo-SQL statement:

SELECT *, <output array field>
FROM collection
WHERE <output array field> IN (SELECT <documents as determined from the pipeline>
                               FROM <collection to join>
                               WHERE <pipeline> );

Mongo URL

Using toIntExact(long value) returns the value of the long argument, throwing an exception if the value overflows an int. it will work only API level 24 or above.

int id = Math.toIntExact(longId);

Use NetworkCredential

Yep, just add these two lines to your code.

var credentials = new System.Net.NetworkCredential("username", "password");

client.Credentials = credentials;

Found this:

The configuration option config.serve_static_assets has been renamed to config.serve_static_files to clarify its role.

in config/environments/production.rb:

# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?

So set env RAILS_SERVE_STATIC_FILES or using Nginx to serving static files. Add config.serve_static_assets = true will still work, but removed in future.

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
  <s:street>Roble Ave</s:street>_x000D_
  <sn:streetNumber>649</sn:streetNumber>_x000D_
  <p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
    parser = new DOMParser();_x000D_
    xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_
}_x000D_
else // Internet Explorer_x000D_
{_x000D_
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");_x000D_
    xmlDoc.async = false;_x000D_
    xmlDoc.loadXML(txt);_x000D_
}_x000D_
_x000D_
//The prefix should not be included when you request the xml namespace_x000D_
//Gets "streetNumber" (note there is no prefix of "sn"_x000D_
console.log(xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Street name_x000D_
console.log(xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Postal Code_x000D_
console.log(xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue);

Not sure if this is still extant but I'm guessing you need something like

((field Like "AA*") AND (field Not Like "BB*"))

In my case nothing above has worked. After banging my head against the wall for a while I've found out, that I've destroyed the /etc/passwd entries by running a custom-made-linux-server-setup-bash-script which worked well previously, but this time the regex within the "sed" command erased all the existing entries :D After copy pasting the default entries from another working linux server I could finally restart sshd.

So don't forget to backup the original /etc/passwd file before applying any regex replacements on it :)

I needed to search for usernames that are similar to each other, and what Ned Batchelder said was incredibly helpful. However, I found I had cleaner output when I used re.compile to create my re search term:

pattern = re.compile(r"("+username+".*):(.*?):(.*?):(.*?):(.*)"
matches = re.findall(pattern, lines)

Output can be printed using the following:

print(matches[1]) # prints one whole matching line (in this case, the first line)
print(matches[1][3]) # prints the fourth character group (established with the parentheses in the regex statement) of the first line.

or if you have a dynamically generated list and you don't know the index but just have the key or id:

let ItemsCopy = []
let x = this.state.Items.map((entry) =>{

    if(entry.id == 'theIDYoureLookingFor')
    {
        entry.PropertyToChange = 'NewProperty'
    }

    ItemsCopy.push(entry)
})


this.setState({Items:ItemsCopy});

I use this code modifying others that I saw. Only grand to the user write if the key pressed or pasted text pass the pattern test (match) (this example is a text input that only allows 8 digits)

$("input").on("keypress paste", function(e){
    var c = this.selectionStart, v = $(this).val();
    if (e.type == "keypress")
        var key = String.fromCharCode(!e.charCode ? e.which : e.charCode)
    else
        var key = e.originalEvent.clipboardData.getData('Text')
    var val = v.substr(0, c) + key + v.substr(c, v.length)
    if (!val.match(/\d{0,8}/) || val.match(/\d{0,8}/).toString() != val) {
        e.preventDefault()
        return false
    }
})

The first variant is indeed more efficient than the second when the function is called either zero or one times. With the second and subsequent invocations, however, the "import every call" approach is actually less efficient. See this link for a lazy-loading technique that combines the best of both approaches by doing a "lazy import".

But there are reasons other than efficiency why you might prefer one over the other. One approach is makes it much more clear to someone reading the code as to the dependencies that this module has. They also have very different failure characteristics -- the first will fail at load time if there's no "datetime" module while the second won't fail until the method is called.

Added Note: In IronPython, imports can be quite a bit more expensive than in CPython because the code is basically being compiled as it's being imported.

innerHTML explanation with example:

The innerHTML manipulates the HTML content of an element(get or set). In the example below if you click on the Change Content link it's value will be updated by using innerHTML property of anchor link Change Content

Example:

<a id="example" onclick='testFunction()'>Change Content</a>_x000D_
_x000D_
<script>_x000D_
  function testFunction(){_x000D_
    // change the content using innerHTML_x000D_
    document.getElementById("example").innerHTML = "This is dummy content";_x000D_
_x000D_
    // get the content using innerHTML_x000D_
    alert(document.getElementById("example").innerHTML)_x000D_
_x000D_
  }_x000D_
</script>_x000D_
    

You can coalesce your NULLs in the ORDER BY statement:

select * from tablename
where <conditions>
order by
    coalesce(position, 0) ASC, 
    id DESC

If you want the NULLs to sort on the bottom, try coalesce(position, 100000). (Make the second number bigger than all of the other position's in the db.)

Components

1. To register a component we use @Component meta-data annotation.
2. Component is a directive which uses shadow DOM to create encapsulated visual behavior called components. Components are typically used to create UI widgets.
3. Component is used to break up the application into smaller components.
4. Only one component can be present per DOM element.
5. @View decorator or templateurl template are mandatory in the component.

Directive

1. To register directives we use @Directive meta-data annotation.
2. Directive is used to add behavior to an existing DOM element.
3. Directive is use to design re-usable components.
4. Many directives can be used per DOM element.
5. Directive doesn't use View.

Those do both mean non-breaking space, yes.   is another synonym, in hex.

This is not a PowerShell-specific answer, but you could authenticate against the share using "NET USE" first:

net use \\server\share /user:<domain\username> <password>

And then do whatever you need to do in PowerShell...

You can use a node.js extension to provide bindings for your C++ code. Here is one tutorial that covers that:

http://syskall.com/how-to-write-your-own-native-nodejs-extension

Use the Apache Commons CLI library commandline.getArgs() to get arg1, arg2, arg3, and arg4. Here is some code:

    import org.apache.commons.cli.CommandLine;
    import org.apache.commons.cli.Option;
    import org.apache.commons.cli.Options;
    import org.apache.commons.cli.Option.Builder;

    public static void main(String[] parameters)
    {
        CommandLine commandLine;
        Option option_A = Option.builder("A")
            .required(true)
            .desc("The A option")

        try

            commandLine = parser.parse(options, testArgs);

            if (commandLine.hasOption("A"))

                {
                    System.out.print(argument);
                    System.out.print(" ");
                }

                System.out.println();
            }

        }
        catch (ParseException exception)
        {
            System.out.print("Parse error: ");
            System.out.println(exception.getMessage());
        }
    }

Here is a fetch POST example. You can do the same for DELETE.

function createNewProfile(profile) {
    const formData = new FormData();
    formData.append('first_name', profile.firstName);
    formData.append('last_name', profile.lastName);
    formData.append('email', profile.email);

    return fetch('http://example.com/api/v1/registration', {
        method: 'POST',
        body: formData
    }).then(response => response.json())
}

createNewProfile(profile)
   .then((json) => {
       // handle success
    })
   .catch(error => error);

Unlike in Python 2, the zip function in Python 3 returns an iterator. Iterators can only be exhausted (by something like making a list out of them) once. The purpose of this is to save memory by only generating the elements of the iterator as you need them, rather than putting it all into memory at once. If you want to reuse your zipped object, just create a list out of it as you do in your second example, and then duplicate the list by something like

 test2 = list(zip(lis1,lis2))
 zipped_list = test2[:]
 zipped_list_2 = list(test2)

the key point is finding the right path where your grunt was installed. I installed grunt through npm, but my grunt path was /Users/${whoyouare}/.npm-global/lib/node_modules/grunt/bin/grunt. So after I added /Users/${whoyouare}/.npm-global/lib/node_modules/grunt/bin to ~/.bash_profile,and source ~/.bash_profile, It worked.

So the steps are as followings:

1. find the path where your grunt was installed(when you installed grunt, it told you. if you don't remember, you can install it one more time)

2. vi ~/.bash_profile

3. export PATH=$PATH:/your/path/where/grunt/was/installed

4. source ~/.bash_profile

You could just put the letter X in the HTML inside the div and then style it with css.

See JSFiddle: http://jsfiddle.net/uSwbN/

HTML:

<div id="orangeBox">
  <span id="x">X</span>
</div>

CSS:

#orangeBox {
  background: #f90;
  color: #fff;
  font-family: 'Helvetica', 'Arial', sans-serif;
  font-size: 2em;
  font-weight: bold;
  text-align: center;
  width: 40px;
  height: 40px;
  border-radius: 5px;
}

Better use Uri.IsWellFormedUriString(string uriString, UriKind uriKind). http://msdn.microsoft.com/en-us/library/system.uri.iswellformeduristring.aspx

Example :-

 if(Uri.IsWellFormedUriString(slct.Text,UriKind.Absolute))
 {
        Uri uri = new Uri(slct.Text);
        if (DeleteFileOnServer(uri))
        {
          nn.BalloonTipText = slct.Text + " has been deleted.";
          nn.ShowBalloonTip(30);
        }
 }

for all views (you need dba privileges for this query)

select view_name from dba_views

for all accessible views (accessible by logged user)

select view_name from all_views

for views owned by logged user

select view_name from user_views

I hacked together another way to do it without having to manipulate list view. Unfortunately, regular Android Animations seem to manipulate the contents of the row, but are ineffectual at actually shrinking the view. So, first consider this handler:

private Handler handler = new Handler() {
@Override
public void handleMessage(Message message) {
    Bundle bundle = message.getData();

    View view = listView.getChildAt(bundle.getInt("viewPosition") - 
        listView.getFirstVisiblePosition());

    int heightToSet;
    if(!bundle.containsKey("viewHeight")) {
        Rect rect = new Rect();
        view.getDrawingRect(rect);
        heightToSet = rect.height() - 1;
    } else {
        heightToSet = bundle.getInt("viewHeight");
    }

    setViewHeight(view, heightToSet);

    if(heightToSet == 1)
        return;

    Message nextMessage = obtainMessage();
    bundle.putInt("viewHeight", (heightToSet - 5 > 0) ? heightToSet - 5 : 1);
    nextMessage.setData(bundle);
    sendMessage(nextMessage);
}

Add this collection to your List adapter:

private Collection<Integer> disabledViews = new ArrayList<Integer>();

and add

public boolean isEnabled(int position) {
   return !disabledViews.contains(position);
}

Next, wherever it is that you want to hide a row, add this:

Message message = handler.obtainMessage();
Bundle bundle = new Bundle();
bundle.putInt("viewPosition", listView.getPositionForView(view));
message.setData(bundle);
handler.sendMessage(message);    
disabledViews.add(listView.getPositionForView(view));

That's it! You can change the speed of the animation by altering the number of pixels that it shrinks the height at once. Not real sophisticated, but it works!

.NET can do it with its System.Speech namespace.

You would have to convert to .wav first or capture the audio live from the mic.

RegQueryValueEx

This gives the value if it exists, and returns an error code ERROR_FILE_NOT_FOUND if the key doesn't exist.

I would point a beginner to the Wiki article on the Main function, then supplement it with this.

• Java only starts running a program with the specific public static void main(String[] args) signature, and one can think of a signature like their own name - it's how Java can tell the difference between someone else's main() and the one true main().

• String[] args is a collection of Strings, separated by a space, which can be typed into the program on the terminal. More times than not, the beginner isn't going to use this variable, but it's always there just in case.

A little late to the party, but I think regular expressions are not the right tool for the job.

The problem is that you'll come across edge cases which would add extranous complexity to the regular expression. @est mentioned an example line:

for (int i = 0; i < 10; doSomethingTo("("));

This string literal contains an (unbalanced!) parenthesis, which breaks the logic. Apparently, you must ignore contents of string literals. In order to do this, you must take the double quotes into account. But string literals itself can contain double quotes. For instance, try this:

for (int i = 0; i < 10; doSomethingTo("\"(\\"));

If you address this using regular expressions, it'll add even more complexity to your pattern.

I think you are better off parsing the language. You could, for instance, use a language recognition tool like ANTLR. ANTLR is a parser generator tool, which can also generate a parser in Python. You must provide a grammar defining the target language, in your case C++. There are already numerous grammars for many languages out there, so you can just grab the C++ grammar.

Then you can easily walk the parser tree, searching for empty statements as while or for loop body.

I had similar expirience like yours. I have Denwer server. When I loaded my http://new.new local site without using via script src jquery.min.js file at index.php in Chrome I got error 500 jquery.min.map in console. I resolved this problem simply - I disabled extension Wunderlist in Chrome and voila - I never see this error more. Although, No, I found this error again - when Wunderlist have been on again. So, check your extensions and try to disable all of them or some of them or one by one. Good luck!

ConfigurationSettings.AppSettings is obsolete, you should use ConfigurationManager.AppSettings instead (you will need to add a reference to System.Configuration)

int value = Int32.Parse(ConfigurationManager.AppSettings["StartingMonthColumn"]);

If you still have problems reading in your app settings then check that your app.config file is named correctly. Specifically, it should be named according to the executing assembly i.e. MyApp.exe.config, and should reside in the same directory as MyApp.exe.

In a very Simple Language.
The mistake is you are using a variable $user_location which is not defined by you earlier and it doesn't have any value So I recommend you to please declare this variable before using it, For Example:

Try this:

myApp.service('userService', [
    '$http', '$q', '$rootScope', '$location', function($http, $q, $rootScope, $location) {
      var deferred= $q.defer();
      this.user = {
        access: false
      };
      try
      {
      this.isAuthenticated = function() {
        this.user = {
          first_name: 'First',
          last_name: 'Last',
          email: '[email protected]',
          access: 'institution'
        };
        deferred.resolve();
      };
    }
    catch
    {
        deferred.reject();
    }

    return deferred.promise;
  ]);

What also works well is the SuppressWithNearbyCommentFilter which uses individual comments to suppress audit events.

For example

// CHECKSTYLE IGNORE check FOR NEXT 1 LINES
public void onClick(View view) { ... }

To configure a filter so that CHECKSTYLE IGNORE check FOR NEXT var LINES avoids triggering any audits for the given check for the current line and the next var lines (for a total of var+1 lines):

<module name="SuppressWithNearbyCommentFilter">
    <property name="commentFormat" value="CHECKSTYLE IGNORE (\w+) FOR NEXT (\d+) LINES"/>
    <property name="checkFormat" value="$1"/>
    <property name="influenceFormat" value="$2"/>
</module>

You can set proxies using environment variables.

import os
os.environ['http_proxy'] = '127.0.0.1'
os.environ['https_proxy'] = '127.0.0.1'

urllib2 will add proxy handlers automatically this way. You need to set proxies for different protocols separately otherwise they will fail (in terms of not going through proxy), see below.

For example:

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
# next line will fail (will not go through the proxy) (https)
urllib2.urlopen('https://www.google.com')

Instead

proxy = urllib2.ProxyHandler({
    'http': '127.0.0.1',
    'https': '127.0.0.1'
})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
# this way both http and https requests go through the proxy
urllib2.urlopen('http://www.google.com')
urllib2.urlopen('https://www.google.com')

@OMG Ponies - One of my reasons of not using the following code

SELECT t.col1 as a, 
     CASE WHEN t.col1 = 'test' THEN 'yes' END as value 
FROM TABLE t;

can be that the t.col1 is not an actual column in the table. For example, it can be a value from a XML column like

Select XMLColumnName.value('(XMLPathOfTag)[1]', 'varchar(max)') 
as XMLTagAlias from Table

Output size of sha1 is 160 bits. Which is 160/8 == 20 chars (if you use 8-bit chars) or 160/16 = 10 (if you use 16-bit chars).

It works better

CREATE TABLE [dbo].[T_Status](
   [Status] [nvarchar](20) NULL
) ON [PRIMARY]

GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'Active')
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'notActive')
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'Active')
GO

DECLARE @GetStatus nvarchar(20) = null
--DECLARE @GetStatus nvarchar(20) = 'Active'
SELECT [Status]
FROM [T_Status]
WHERE  [Status] = CASE WHEN (isnull(@GetStatus, '')='') THEN [Status]
ELSE @GetStatus END

Yes, you can like this:

I know this question is quite old, but I have found a nice solution. Basically, you pass a container layout to this function, and it will apply the font to all supported views, and recursively cicle in child layouts:

public static void setFont(ViewGroup layout)
{
    final int childcount = layout.getChildCount();
    for (int i = 0; i < childcount; i++)
    {
        // Get the view
        View v = layout.getChildAt(i);

        // Apply the font to a possible TextView
        try {
            ((TextView) v).setTypeface(MY_CUSTOM_FONT);
            continue;
        }
        catch (Exception e) { }

        // Apply the font to a possible EditText
        try {
            ((TextView) v).setTypeface(MY_CUSTOM_FONT);
            continue;
        }
        catch (Exception e) { }

        // Recursively cicle into a possible child layout
        try {
            ViewGroup vg = (ViewGroup) v;
            Utility.setFont(vg);
            continue;
        }
        catch (Exception e) { }
    }
}

From python >= 3.5 onward, you can use **, glob.iglob(path/**, recursive=True) and it seems the most pythonic solution, i.e.:

import glob, os

for filename in glob.iglob('/pardadox-music/**', recursive=True):
    if os.path.isfile(filename): # filter dirs
        print(filename)

Output:

/pardadox-music/modules/her1.mod
/pardadox-music/modules/her2.mod
...

Notes:
1 - glob.iglob

glob.iglob(pathname, recursive=False)

Return an iterator which yields the same values as glob() without actually storing them all simultaneously.

2 - If recursive is True, the pattern '**' will match any files and zero or more directories and subdirectories.

3 - If the directory contains files starting with . they won’t be matched by default. For example, consider a directory containing card.gif and .card.gif:

>>> import glob
>>> glob.glob('*.gif') ['card.gif'] 
>>> glob.glob('.c*')['.card.gif']

4 - You can also use rglob(pattern), which is the same as calling glob() with **/ added in front of the given relative pattern.

Here is the function I use. Created based on @Lauer answer above and some other resources:

//Get Columns
function getColumns($tablenames) {
global $hostname , $dbnames, $username, $password;
try {
$condb = new PDO("mysql:host=$hostname;dbname=$dbnames", $username, $password);

//debug connection
$condb->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$condb->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// get column names
$query = $condb->prepare("DESCRIBE $tablenames");
$query->execute();
$table_names = $query->fetchAll(PDO::FETCH_COLUMN);
return $table_names;

//Close connection
$condb = null;

} catch(PDOExcepetion $e) {
echo $e->getMessage();
}
}

Usage Example:

$columns = getColumns('name_of_table'); // OR getColumns($name_of_table); if you are using variable.

foreach($columns as $col) {
echo $col . '<br/>';
}

Here is an interesting case: method receieves generic collection and returns generic collection of same base type. For example:

Collection<? extends Assertion> map(Collection<? extends Assertion> assertions);

This method can be mocked with combination of Mockito anyCollectionOf matcher and the Answer.

when(mockedObject.map(anyCollectionOf(Assertion.class))).thenAnswer(
     new Answer<Collection<Assertion>>() {
         @Override
         public Collection<Assertion> answer(InvocationOnMock invocation) throws Throwable {
             return new ArrayList<Assertion>();
         }
     });

I hope this code will help someone - it is from official Google Firebase documentation:

var adaRef = firebase.database().ref('users/ada');
adaRef.remove()
  .then(function() {
    console.log("Remove succeeded.")
  })
  .catch(function(error) {
    console.log("Remove failed: " + error.message)
  });

give the same command as you used to give while installing a single module only pass it via space delimited format

am assuming that you want to know how to format numbers in SSRS

Just right click the TextBox on which you want to apply formatting, go to its expression.

suppose its expression is something like below

=Fields!myField.Value

then do this

=Format(Fields!myField.Value,"##.##") 

or

=Format(Fields!myFields.Value,"00.00")

difference between the two is that former one would make 4 as 4 and later one would make 4 as 04.00

this should give you an idea.

also: you might have to convert your field into a numerical one. i.e.

  =Format(CDbl(Fields!myFields.Value),"00.00")

so: 0 in format expression means, when no number is present, place a 0 there and # means when no number is present, leave it. Both of them works same when numbers are present ie. 45.6567 would be 45.65 for both of them:

UPDATE :

if you want to apply variable formatting on the same column based on row values i.e. you want myField to have no formatting when it has no decimal value but formatting with double precision when it has decimal then you can do it through logic. (though you should not be doing so)

Go to the appropriate textbox and go to its expression and do this:

=IIF((Fields!myField.Value - CInt(Fields!myField.Value)) > 0, 
    Format(Fields!myField.Value, "##.##"),Fields!myField.Value)

so basically you are using IIF(condition, true,false) operator of SSRS, ur condition is to check whether the number has decimal value, if it has, you apply the formatting and if no, you let it as it is.

this should give you an idea, how to handle variable formatting.

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

In jQuery there is $.isPlainObject() method for that:

Description: Check to see if an object is a plain object (created using "{}" or "new Object").

Win32_Product never shows everything, only software installed via an MSI installer (as far as I can tell.)

There are lots of software packages that get installed via other installers that don't show up in there. another way is needed.

This works:

insert into TABLE_NAME (COL1,COL2)
select my_seq.nextval, a
from
(SELECT 'SOME VALUE' as a FROM DUAL
 UNION ALL
 SELECT 'ANOTHER VALUE' FROM DUAL)

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

Oh, I found it. You use last instead of break

for my $entry (@array){
    if ($string eq "text"){
         last;
    }
}

A simple one liner:

$("#text").val( $("#text").val().replace(".", ":") );

Most answers suggest to just add ServerName localhost to /etc/apache2/apache2.conf.

But quoting Apache documentation :

The presence of this error message also indicates that Apache httpd was unable to obtain a fully-qualified hostname by doing a reverse lookup on your server's IP address. While the above instructions will get rid of the warning in any case, it is also a good idea to fix your name resolution so that this reverse mapping works.

Therefore adding such a line to /etc/hosts is probably a more robust solution :

192.0.2.0  foobar.example.com  foobar

where 192.0.2.0 is the static IP address of the server named foobar within the example.com domain.

One can check the FQDN e.g. with

hostname -A

(shortcut for hostname --all-fqdn).

In Vim, use :insert. This will keep all your formatting and not do autoindenting. For more information help :insert.

SELECT COUNT(1)
FROM FB

    Dte BETWEEN CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(DATEADD(month, -1, GETDATE())) AS VARCHAR(2)) + '-20 00:00:00'

A console application does not automatically add a reference to System.Windows.Forms.dll.

Right-click your project in Solution Explorer and select Add reference... and then find System.Windows.Forms and add it.

You can use Comparator.reverseOrder() to have a comparator giving the reverse of the natural ordering.

If you want to reverse the ordering of an existing comparator, you can use Comparator.reversed().

Sample code:

Stream.of(1, 4, 2, 5)
    .sorted(Comparator.reverseOrder()); 
    // stream is now [5, 4, 2, 1]

Stream.of("foo", "test", "a")
    .sorted(Comparator.comparingInt(String::length).reversed()); 
    // stream is now [test, foo, a], sorted by descending length

I had the same issue, unable to resize the image when adjusting browser dimensions.

Bad Code:

html {  
  background-color: white;  
  background-image: url("example.png");  
  background-repeat: no-repeat;  
  background-attachment: scroll;  
  background-position: 0% 0%;
}

Good Code:

html {  
  background-color: white;  
  background-image: url("example.png");  
  background-repeat: no-repeat;  
  background-attachment: scroll;  
  background-position: 0% 0%;
  background-size: contain;
}

The key here is the addition of this element -> background-size: contain;

This has changed in Scala 2.8 which has a mechanism for using breaks. You can now do the following:

import scala.util.control.Breaks._
var largest = 0
// pass a function to the breakable method
breakable { 
    for (i<-999 to 1  by -1; j <- i to 1 by -1) {
        val product = i * j
        if (largest > product) {
            break  // BREAK!!
        }
        else if (product.toString.equals(product.toString.reverse)) {
            largest = largest max product
        }
    }
}

In addition to what provided in the other answers, the keyword "zorder" allows one to decide the order in which different objects are plotted vertically. E.g.:

plt.plot(x,y,zorder=1) 
plt.scatter(x,y,zorder=2)

plots the scatter symbols on top of the line, while

plt.plot(x,y,zorder=2)
plt.scatter(x,y,zorder=1)

plots the line over the scatter symbols.

See, e.g., the zorder demo

I found a Problem with marquee that it can't be used for short strings(As its function is only to Show Long strings).

I suggest Use Webview If you want to move short strings horizontally. Main_Activity.java Code:`

        WebView webView;

        webView = (WebView)findViewById(R.id.web);


        String summary = "<html><FONT color='#fdb728' FACE='courier'><marquee behavior='scroll' direction='left' scrollamount=10>"
                + "Hello Droid" + "</marquee></FONT></html>";

        webView.loadData(summary, "text/html", "utf-8"); // Set focus to the textview
`

main_activity.xml code:

<WebView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/web"
        ></WebView>

For Spyder 3: In case you don't find Preferences under Tools > Preferences, thats probably because Preferences is pinned onto your tool bar by default Preferences in Tool Bar

You will need to melt your dataframe to get it into the so-called long format:

require(reshape2)
sample.data.M <- melt(sample.data)

Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:

require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")

Instead of stacking you may also be interested in showing multiple plots using facets:

c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")

JaredPar,

This did not work for me if I pass typeof(type<>) as toCheck. Here's what I changed.

static bool IsSubclassOfRawGeneric(Type generic, Type toCheck) {
    while (toCheck != typeof(object)) {
        var cur = toCheck.IsGenericType ? toCheck.GetGenericTypeDefinition() : toCheck;
          if (cur.IsGenericType && generic.GetGenericTypeDefinition() == cur.GetGenericTypeDefinition()) {
            return true;
        }
        toCheck = toCheck.BaseType;
    }
    return false;
}

There are 3 different methods depending on what I is my requirement and which version I am using.

Here are the methods..

1) Using Convert

DECLARE @DateTime DATETIME = GETDATE();
--Using Convert
SELECT
    CONVERT(NVARCHAR, @DateTime,120) AS 'myDateTime'
    ,CONVERT(NVARCHAR(10), @DateTime, 120) AS 'myDate'
    ,RIGHT(CONVERT(NVARCHAR, @DateTime, 120),8) AS 'myTime'

2) Using Cast (SQL Server 2008 and beyond)

SELECT
    CAST(@DateTime AS DATETIME2) AS 'myDateTime'
    ,CAST(@DateTime AS DATETIME2(3)) AS 'myDateTimeWithPrecision'
    ,CAST(@DateTime AS DATE) AS 'myDate'
    ,CAST(@DateTime AS TIME) AS 'myTime'
    ,CAST(@DateTime AS TIME(3)) AS 'myTimeWithPrecision'

3) Using Fixed-length character data type

DECLARE @myDateTime NVARCHAR(20) = CONVERT(NVARCHAR, @DateTime, 120);
DECLARE @myDate NVARCHAR(10) = CONVERT(NVARCHAR, @DateTime, 120);

SELECT
    @myDateTime AS 'myDateTime'
    ,@myDate AS 'myDate'

Also take a look at ILSpy by SharpDevelop. It's in early stages of development and they just made a release on the 24th of February. That in itself works pretty good for me. From their website:

ILSpy is the open-source .NET assembly browser and decompiler.

Development started after Red Gate announced that the free version of .NET Reflector would cease to exist by end of February 2011.

Update: JetBrains has released dotPeek, its free .NET decompiler.

Update 2: Telerik also has a free decompiler: JustDecompile.

Run the installer from command line with argument /CustomInstallPath InstallationDirectory

See more command-line parameters and other installation information.

Note: this won't change location of all files, but only of those which can be (by design) installed onto different location. Be warned that there is many shared components which will be installed into shared repositories on drive C: without any possibility to change their path (unless you do some hacking using mklink /j (directory junction, i.e."hard link for folder"), but it is questionable whether it is worth it, because any Visual Studio updates will break those hard links. This is confirmed by people who tried that, although on Visual Studio 2012.)

Update: per recent comment, uninstallation of Visual Studio might be required before the above applies. Uninstallation command is like this: vs_community_ENU.exe /uninstall /force

Set the value of the input to null on each onclick event. This will reset the input's value and trigger the onchange event even if the same path is selected.

input.onclick = function () {
    this.value = null;
};

input.onchange = function () {
    alert(this.value);
};?

Here's a DEMO.

Note: It's normal if your file is prefixed with 'C:\fakepath\'. That's a security feature preventing JavaScript from knowing the file's absolute path. The browser still knows it internally.

Swift 3

The most upvoted answer is not correct for Swift 3.

The correct code to change color is:

self.navigationController?.navigationBar.tintColor = UIColor.white

If you want to change color, change UIColor.white above to the desired color

I Found Solution Of You Question But In Stack Not Allow to Upload Video See the link below it show better explain

How to link two (multiple) workbooks and cells in Excel...

In the case you want to format it within a formula (for example, if you are concatenating strings and values), the aforementioned format option of Google is not available, but you can use the TEXT formula:

=TEXT(B1-C1,"HH:MM:SS")

Therefore, for the questioned example, with concatenation:

="The number of " & TEXT(B1,"HH") & " hour slots in " & TEXT(C1,"HH") _
& " is " & TEXT(C1/B1,"HH")

You can solve this by having a long stripe that you show in steps, like a filmstrip. Then you can stop the film on any frame. Example below (fiddle available at http://jsfiddle.net/HPXq4/9/):

the markup:

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

the css:

.thumbnail-wrapper{
   width:190px;
   height:100px;
   overflow:hidden;
   position:absolute;
}
.thumbnail-wrapper img{
   position:relative;
   top:0;
}

the js:

var gifTimer;
var currentGifId=null;
var step = 100; //height of a thumbnail
$('.thumbnail-wrapper img').hover(
   function(){
      currentGifId = $(this)
      gifTimer = setInterval(playGif,500);
   },
   function(){
       clearInterval(gifTimer);
       currentGifId=null;
   }
);

var playGif = function(){
   var top = parseInt(currentGifId.css('top'))-step;
   var max = currentGifId.height();
   console.log(top,max)
   if(max+top<=0){
     console.log('reset')
     top=0;
   }
   currentGifId.css('top',top);
}

obviously, this can be optimized much further, but I simplified this example for readability

func sum(array : [Int]) -> Int{
    var sum = 0
    array.forEach { (item) in
        sum = item + sum
    }
    return sum
}
func susetNumbers(array :[Int], target : Int, subsetArray: [Int],result : inout [[Int]]) -> [[Int]]{
    let s = sum(array: subsetArray)
    if(s == target){
        print("sum\(subsetArray) = \(target)")
        result.append(subsetArray)
    }
    for i in 0..<array.count{
        let n = array[i]
        let remaning = Array(array[(i+1)..<array.count])
        susetNumbers(array: remaning, target: target, subsetArray: subsetArray + [n], result: &result)
        
    }
    return result
}

 var resultArray = [[Int]]()
    let newA = susetNumbers(array: [1,2,3,4,5], target: 5, subsetArray: [],result:&resultArray)
    print(resultArray)

This should work.

<!DOCTYPE html>

The background colors are there so you can see how this works. Copy this code to a file and open it in your browser. Try playing around with the CSS a bit and see what happens.

The width: inherit; height: inherit; pulls the width and height from the parent element. This should be the default and is not truly necessary.

Try removing the h1 { ... } CSS block and see what happens. You might notice the layout reacts in an odd way. This is because the h1 element is influencing the layout of its container. You could prevent this by declaring overflow: hidden; on the container or the body.

I'd also suggest you do some reading on the CSS Box Model.

It is possible to set environment variables on Mac OS X 10.10 Yosemite with 3 files + 2 commands.

Main file with environment variables definition:

$ ls -la /etc/environment 
-r-xr-xr-x  1 root  wheel  369 Oct 21 04:42 /etc/environment
$ cat /etc/environment
#!/bin/sh

set -e

syslog -s -l warn "Set environment variables with /etc/environment $(whoami) - start"

launchctl setenv JAVA_HOME      /usr/local/jdk1.7
launchctl setenv MAVEN_HOME     /opt/local/share/java/maven3

if [ -x /usr/libexec/path_helper ]; then
    export PATH=""
    eval `/usr/libexec/path_helper -s`
    launchctl setenv PATH $PATH
fi

osascript -e 'tell app "Dock" to quit'

syslog -s -l warn "Set environment variables with /etc/environment $(whoami) - complete"

Service definition to load environment variables for user applications (terminal, IDE, ...):

$ ls -la /Library/LaunchAgents/environment.user.plist
-rw-------  1 root  wheel  504 Oct 21 04:37 /Library/LaunchAgents/environment.user.plist
$ sudo cat /Library/LaunchAgents/environment.user.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>environment.user</string>
    <key>ProgramArguments</key>
    <array>
            <string>/etc/environment</string>
    </array>
    <key>KeepAlive</key>
    <false/>
    <key>RunAtLoad</key>
    <true/>
    <key>WatchPaths</key>
    <array>
        <string>/etc/environment</string>
    </array>
</dict>
</plist>

The same service definition for root user applications:

$ ls -la /Library/LaunchDaemons/environment.plist
-rw-------  1 root  wheel  499 Oct 21 04:38 /Library/LaunchDaemons/environment.plist
$ sudo cat /Library/LaunchDaemons/environment.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>environment</string>
    <key>ProgramArguments</key>
    <array>
            <string>/etc/environment</string>
    </array>
    <key>KeepAlive</key>
    <false/>
    <key>RunAtLoad</key>
    <true/>
    <key>WatchPaths</key>
    <array>
        <string>/etc/environment</string>
    </array>
</dict>
</plist>

And finally we should register these services:

$ launchctl load -w /Library/LaunchAgents/environment.user.plist
$ sudo launchctl load -w /Library/LaunchDaemons/environment.plist

What we get:

1. The only place to declare system environment variables: /etc/environment
2. Instant auto-update of environment variables after modification of /etc/environment file - just relaunch your application

Issues / problems:

In order your env variables were correctly taken by applications after system reboot you will need:

• either login twice: login => logout => login
• or close & re-open applications manually, where env variables should be taken
• or do NOT use feature "Reopen windows when logging back".

This happens due to Apple denies explicit ordering of loaded services, so env variables are registered in parallel with processing of the "reopen queue".

But actually, I reboot my system only several times per year (on big updates), so it is not a big deal.

If you do not wan't to blindly trust everybody and make a trust exception only for certain hosts the following solution is more appropriate.

public static class Ssl
{
    private static readonly string[] TrustedHosts = new[] {
      "host1.domain.com", 
      "host2.domain.com"
    };

    public static void EnableTrustedHosts()
    {
      ServicePointManager.ServerCertificateValidationCallback = 
      (sender, certificate, chain, errors) =>
      {
        if (errors == SslPolicyErrors.None)
        {
          return true;
        }

        var request = sender as HttpWebRequest;
        if (request != null)
        {
          return TrustedHosts.Contains(request.RequestUri.Host);
        }

        return false;
      };
    }
}

Then just call Ssl.EnableTrustedHosts when your app starts.

Adding to @Josh's example;

fName = [FILE TO OPEN]
if os.path.exists(fName):
    with open(fName, 'rb') as f:
        #add you code to handle the file contents here.
elif IOError:
    print "Unable to open file: "+str(fName)

This way you can attempt to open the file, but if it doesn't exist (if it raises an IOError), alert the user!

If you want to use default value for a DateTime parameter in a method, you can only use default(DateTime).

The following line will not compile:

    private void MyMethod(DateTime syncedTime = DateTime.MinValue)

This line will compile:

    private void MyMethod(DateTime syncedTime = default(DateTime))

Oh Raphael has moved on significantly since June. There is a new charting library that can work with it and these are very eye catching. Raphael also supports full SVG path syntax and is incorporating really advanced path methods. Come see 1.2.8+ at my site (Shameless plug) and then bounce over to the Dmitry's site from there. http://www.irunmywebsite.com/raphael/raphaelsource.html

I'd like to add this because I spent some time solving the issue and did not find an answer here for combination of variables usage in cron and virtualenv. So maybe it'll help someone.

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DIR_SMTH="cd /smth"
VENV=". venv/bin/activate"
CMD="some_python_bin do_something"
# m h  dom mon dow   command
0 * * * * $DIR_SMTH && $VENV && $CMD -k2 some_target >> /tmp/crontest.log 2>&1

It did not work well when it was configured like

DIR_SMTH="cd /smth && . venv/bin/activate"

Thanks @davidwinterbottom, @reed-sandberg and @mkb for giving the right direction. The accepted answer actually works fine until your python need to run a script which have to run another python binary from venv/bin directory.

I had to transfer texts from an Excel file to an xliff file. We had some texts that were originally in uppercase but those translators didn't use uppercase so I used notepad++ as intermediate to do the conversion.

Since I had the mouse in one hand (to mark in Excel and activate the different windows) I disliked the predefined shortcut (Ctrl+Shift+U) as "U" is too far away for my left hand. I first switched it to Ctrl+Shift+X which worked.

Then I realized, that you can create macros easily, so I recorded one doing:

• mark all
• paste from clipboard
• convert to upppercase
• copy to clipboard

That macro got assigned that very shortcut (Ctrl+Shift+X) and made my life easy :)

Consider this example for easy understanding.

What does telecommunication companies provide? Broadband, phone line and mobile for instance and you're asked to create an application to offer their products to their customers.

Generally what you'd do here is, creating the products i.e broadband, phone line and mobile are through your Factory Method where you know what properties you have for those products and it's pretty straightforward.

Now, the company wants to offer their customer a bundle of their products i.e broadband, phone line, and mobile altogether, and here comes the Abstract Factory to play.

Abstract Factory is, in other words, are the composition of other factories who are responsible for creating their own products and Abstract Factory knows how to place these products in more meaningful in respect of its own responsibilities.

In this case, the BundleFactory is the Abstract Factory, BroadbandFactory, PhonelineFactory and MobileFactory are the Factory. To simplify more, these Factories will have Factory Method to initialise the individual products.

Se the code sample below:

public class BroadbandFactory : IFactory {
    public static Broadband CreateStandardInstance() {
        // broadband product creation logic goes here
    }
}

public class PhonelineFactory : IFactory {
    public static Phoneline CreateStandardInstance() {
        // phoneline product creation logic goes here
    }
}

public class MobileFactory : IFactory {
    public static Mobile CreateStandardInstance() {
        // mobile product creation logic goes here
    }
}

public class BundleFactory : IAbstractFactory {

    public static Bundle CreateBundle() {
        broadband = BroadbandFactory.CreateStandardInstance();
        phoneline = PhonelineFactory.CreateStandardInstance();
        mobile = MobileFactory.CreateStandardInstance();

        applySomeDiscountOrWhatever(broadband, phoneline, mobile);
    }

    private static void applySomeDiscountOrWhatever(Broadband bb, Phoneline pl, Mobile m) {
        // some logic here
        // maybe manange some variables and invoke some other methods/services/etc.
    }
}

Hope this helps.

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

You're just missing one critical step. You have to explicitly pass the return value in to the second function.

def main():
    l = defineAList()
    useTheList(l)

Alternatively:

def main():
    useTheList(defineAList())

Or (though you shouldn't do this! It might seem nice at first, but globals just cause you grief in the long run.):

l = []

def defineAList():
    global l
    l.extend(['1','2','3'])

def main():
    global l
    defineAList()
    useTheList(l)

The function returns a value, but it doesn't create the symbol in any sort of global namespace as your code assumes. You have to actually capture the return value in the calling scope and then use it for subsequent operations.

You can use

DispatchQueue.main.asyncAfter(deadline: .now() + .microseconds(100)) {
        // Code
    }

You assign to big and small before the array is initialized, i.e., big and small assume the value of whatever is on the stack at this point. As they are just plain value types and no references, they won't assume a new value once values[0] is written to via cin >>.

Just move the assignment after your first loop and it should be fine.

An alternative to darindaCoder's answer:

path = r'C:\DRO\DCL_rawdata_files'                     # use your path
all_files = glob.glob(os.path.join(path, "*.csv"))     # advisable to use os.path.join as this makes concatenation OS independent

df_from_each_file = (pd.read_csv(f) for f in all_files)
concatenated_df   = pd.concat(df_from_each_file, ignore_index=True)
# doesn't create a list, nor does it append to one

I think you just need;

List<string> list = new List<string>();
list.Add("hai");

There is a difference between

List<string> list; 

and

List<string> list = new List<string>();

When you didn't use new keyword in this case, your list didn't initialized. And when you try to add it hai, obviously you get an error.

Well it's 2016 and there is still no easy way to do a combo ... sure we have datalist but without safari/ios support it's not really usable. At least we have ES6 .. below is an attempt at a combo class that wraps a div or span, turning it into a combo by putting an input box on top of select and binding the relevant events.

see the code at: https://github.com/kofifus/Combo

(the code relies on the class pattern from https://github.com/kofifus/New)

Creating a combo is easy ! just pass a div to it's constructor:

let mycombo=Combo.New(document.getElementById('myCombo'));_x000D_
mycombo.options(['first', 'second', 'third']);_x000D_
_x000D_
mycombo.onchange=function(e, combo) {_x000D_
  let val=combo.value;_x000D_
  // let val=this.value; // same as above_x000D_
  alert(val);_x000D_
 }

<script src="https://rawgit.com/kofifus/New/master/new.min.js"></script>_x000D_
<script src="https://rawgit.com/kofifus/Combo/master/combo.min.js"></script>_x000D_
_x000D_
<div id="myCombo" style="width:100px;height:20px;"></div>

Please install below command using command prompt.

pip install mysql-connector-python

in C++ expression a % b returns remainder of division of a by b (if they are positive. For negative numbers sign of result is implementation defined). For example:

5 % 2 = 1
13 % 5 = 3

With this knowledge we can try to understand your code. Condition count % 6 == 5 means that newline will be written when remainder of division count by 6 is five. How often does that happen? Exactly 6 lines apart (excercise : write numbers 1..30 and underline the ones that satisfy this condition), starting at 6-th line (count = 5).

To get desired behaviour from your code, you should change condition to count % 5 == 4, what will give you newline every 5 lines, starting at 5-th line (count = 4).

I think this will help.It is a simple script which will check if there is a silence or not.If silence is detected it will not record otherwise it will record.

You can add to the system-path at runtime:

import sys
sys.path.insert(0, 'path/to/your/py_file')

import py_file

This is by far the easiest way to do it.

I know this is very old and possibly talking about an older version of Visual studio and so this might not have been an option before but anyway, my way would be when at a breakpoint use the locals window to see all current variable values ( Debug >> Windows >> Locals )

You could put your switch into a separate function like this:

bool myswitchfunction()
{
    switch(msg->state) {
    case MSGTYPE: // ... 
        break;
    // ... more stuff ...
    case DONE:
        return false; // **HERE, I want to break out of the loop itself**
    }
    return true;
}

while(myswitchfunction())
    ;

The agg function will do this for you. Pass the columns and function as a dict with column, output:

df.groupby(['Country', 'Item_Code']).agg({'Y1961': np.sum, 'Y1962': [np.sum, np.mean]})  # Added example for two output columns from a single input column

This will display only the group by columns, and the specified aggregate columns. In this example I included two agg functions applied to 'Y1962'.

To get exactly what you hoped to see, included the other columns in the group by, and apply sums to the Y variables in the frame:

df.groupby(['Code', 'Country', 'Item_Code', 'Item', 'Ele_Code', 'Unit']).agg({'Y1961': np.sum, 'Y1962': np.sum, 'Y1963': np.sum})

This might depend on how much you want to engineer the solution - if the array is never going to be that big and you don't care about sorting the list you might want to try something similar to the following:

    public string[] RemoveDuplicates(string[] myList) {
        System.Collections.ArrayList newList = new System.Collections.ArrayList();

        foreach (string str in myList)
            if (!newList.Contains(str))
                newList.Add(str);
        return (string[])newList.ToArray(typeof(string));
    }

WinSCp now supports S3 protocol

First, make sure your AWS user with S3 access permissions has an “Access key ID” created. You also have to know the “Secret access key”. Access keys are created and managed on Users page of IAM Management Console.

Make sure New site node is selected.

On the New site node, select Amazon S3 protocol.

Enter your AWS user Access key ID and Secret access key

Save your site settings using the Save button.

Login using the Login button.

Several answers already suggest how to query the current python version. To check programmatically the version requirements, I'd make use of one of the following two methods:

# Method 1: (see krawyoti's answer)
import sys
assert(sys.version_info >= (2,6))

# Method 2: 
import platform
from distutils.version import StrictVersion 
assert(StrictVersion(platform.python_version()) >= "2.6")

You would define a constructor in an abstract class if you are in one of these situations:

• you want to perform some initialization (to fields of the abstract class) before the instantiation of a subclass actually takes place
• you have defined final fields in the abstract class but you did not initialize them in the declaration itself; in this case, you MUST have a constructor to initialize these fields

Note that:

• you may define more than one constructor (with different arguments)
• you can (should?) define all your constructors protected (making them public is pointless anyway)
• your subclass constructor(s) can call one constructor of the abstract class; it may even have to call it (if there is no no-arg constructor in the abstract class)

In any case, don't forget that if you don't define a constructor, then the compiler will automatically generate one for you (this one is public, has no argument, and does nothing).

echo off
setlocal
SET AREYOUSURE = N
:PROMPT
set /P AREYOUSURE=Update Release Files (Y/N)?
if /I %AREYOUSURE% NEQ Y GOTO END
set /P AREYOUSURE=Are You Sure you want to Update Release Files (Y/N)?
if /I %AREYOUSURE% NEQ Y GOTO END

echo Copying New Files

:END

This is code I use regularly. I have noticed in the examples in this blog that quotes are used. If the test line is changed to use quotes the test is invalid.

if /I %AREYOUSURE% NEQ "Y" GOTO END

I have tested on XP, Vista, Win7 and Win8. All fail when quotes are used.

I'd use a regular expression:

function someFunction(site)
{
// if site has an end slash (like: www.example.com/),
// then remove it and return the site without the end slash
return site.replace(/\/$/, '') // Match a forward slash / at the end of the string ($)
}

You'll want to make sure that the variable site is a string, though.

With Java 8 we get a new Date / Time API (JSR 310).

The following way can be used to parse the date in Java 8 without relying on Joda-Time:

 String str = "January 2nd, 2010";

// if we 2nd even we have changed in pattern also it is not working please workout with 2nd 
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMMM Q, yyyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse(str, formatter);

// access date fields
int year = date.getYear(); // 2010
int day = date.getDayOfMonth(); // 2
Month month = date.getMonth(); // JANUARY
int monthAsInt = month.getValue(); // 1

LocalDate is the standard Java 8 class for representing a date (without time). If you want to parse values that contain date and time information you should use LocalDateTime. For values with timezones use ZonedDateTime. Both provide a parse() method similar to LocalDate:

LocalDateTime dateWithTime = LocalDateTime.parse(strWithDateAndTime, dateTimeFormatter);
ZonedDateTime zoned = ZonedDateTime.parse(strWithTimeZone, zoneFormatter);

The list formatting characters from DateTimeFormatter Javadoc:

All letters 'A' to 'Z' and 'a' to 'z' are reserved as pattern letters. 
The following pattern letters are defined:

To expand on @Isha's anwser you could just do the following to get the returned output (post-facto not in rea-ltime) of the script that was run:

try {
    Process process = Runtime.getRuntime().exec("cmd /c start D:\\temp\\a.bat");
    System.out.println(process.getText());
} catch(IOException e) {
    e.printStackTrace();
}

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

Everyone is right: stick with POST for non-idempotent requests.

What about using both an URI query string and request content? Well it's valid HTTP (see note 1), so why not?!

It is also perfectly logical: URLs, including their query string part, are for locating resources. Whereas HTTP method verbs (POST - and its optional request content) are for specifying actions, or what to do with resources. Those should be orthogonal concerns. (But, they are not beautifully orthogonal concerns for the special case of ContentType=application/x-www-form-urlencoded, see note 2 below.)

Note 1: HTTP specification (1.1) does not state that query parameters and content are mutually exclusive for a HTTP server that accepts POST or PUT requests. So any server is free to accept both. I.e. if you write the server there's nothing to stop you choosing to accept both (except maybe an inflexible framework). Generally, the server can interpret query strings according to whatever rules it wants. It can even interpret them with conditional logic that refers to other headers like Content-Type too, which leads to Note 2:

Note 2: if a web browser is the primary way people are accessing your web application, and application/x-www-form-urlencoded is the Content-Type they are posting, then you should follow the rules for that Content-Type. And the rules for application/x-www-form-urlencoded are much more specific (and frankly, unusual): in this case you must interpret the URI as a set of parameters, and not a resource location. [This is the same point of usefulness Powerlord raised; that it may be hard to use web forms to POST content to your server. Just explained a little differently.]

Note 3: what are query strings originally for? RFC 3986 defines HTTP query strings as an URI part that works as a non-hierarchical way of locating a resource.

In case readers asking this question wish to ask what is good RESTful architecture: the RESTful architecture pattern doesn't require URI schemes to work a specific way. RESTful architecture concerns itself with other properties of the system, like cacheability of resources, the design of the resources themselves (their behavior, capabilities, and representations), and whether idempotence is satisfied. Or in other words, achieving a design which is highly compatible with HTTP protocol and its set of HTTP method verbs. :-) (In other words, RESTful architecture is not very presciptive with how the resources are located.)

Final note: sometimes query parameters get used for yet other things, which are neither locating resources nor encoding content. Ever seen a query parameter like 'PUT=true' or 'POST=true'? These are workarounds for browsers that don't allow you to use PUT and POST methods. While such parameters are seen as part of the URL query string (on the wire), I argue that they are not part of the URL's query in spirit.

If the file that this script lives in is executable, the hash-bang (#!) tells the operating system what interpreter to use to run the script. In this case it's /bin/sh, for example.

There's a Wikipedia article about it for more information.

I'd probably do something like that :

[int]::Parse("35")

But I'm not really a Powershell guy. It uses the static Parse method from System.Int32. It should throw an exception if the string can't be parsed.

If you're not too attached to your current workspace you can create a new workspace, follow BalusC's steps for server creation, and recreate your project in the new workspace.

I got the same error after installing Eclipse Java EE IDE for Web Developers(Juno) but using the workspace of a much older Eclipse installation. When I created a new workspace I was able to get my Tomcat server running without this error.

#access a {
    border-bottom: 2px solid #fff;
    color: #eee;
    display: block;
    line-height: 3.333em;
    padding: 0 10px 0 20px;
    text-decoration: none;
}

I see that you had used line-height but you gave it to <a> tag instead of <ul> Try this:

#access ul {line-height:3.333em;}

You wouldn't need to play with margins then.

That's not possible. localhost always defaults to the loopback device on the local operating system.
As your virtual machine runs its own operating system it has its own loopback device which you cannot access from the outside.

If you want to access it e.g. in a browser, connect to it using the local IP instead:

http://192.168.180.1:8000

This is just an example of course, you can find out the actual IP by issuing an ifconfig command on a shell in the guest operating system.

I was having same problem and I resolved the issue. Earlier css was overflow:hidden; z-index:999999;

I change it to overflow:visible;

Building up on Danny '365CSI' Engelman's comment, here is an universal solution:

<script>
  alert("This script always runs.");
  script01 = true;
</script>
<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"
 onload="if(typeof script01==='undefined') eval(this.previousElementSibling.innerHTML)">

Use this as innerHTML (i.e. loaded by XMLHttpRequest) or directly (i.e. inserted by PHP backend), the script always loads once.

Explanation: script loaded as innerHTML is not executed, but onload content atribute is. If the script was not executed (added as innerHTML) then the script is executed in image onload event. If the script was loaded (added by backend) then script01 variable is defined and onload will not run the script for the second time.

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Assembly is the fundamental part of programming with .NET Framework. It contain code that CLR executes MSIL(Microsoft Intermediate Language) code in a portable executable file will not be executed if it does not have an associated assembly manifest.

This creates a "jump" due to variable heights... to solve that, try something like this: Select the tallest image of a list

Or use media-query to set your own fixed height.

The solutions offered here and in other places didn't work for me, so I'll add to the discussion for future readers. I admittedly don't fully understand the procedure yet, but have finally solved my (similar) problem and want to share.

I had accidentally cached some doc-directories with several hundred files when working with git in IntelliJ IDEA on Windows 10, and after adding them to .gitignore (and PROBABLY moving them around a bit) I couldn't get them removed from the Default Changelist.

I first commited the actual changes I had made, then went about solving this - took me far too long. I tried git rm -r --cached . but would always get path-spec ERRORS, with different variations of the path-spec as well as with the -f and -r flags.

git status would still show the filenames, so I tried using some of those verbatim with git rm -cached, but no luck. Stashing and unstashing the changes seemed to work, but they got queued again after a time (I'm a bity hazy on the exact timeframe). I have finally removed these entries for good using

git reset

I assume this is only a GOOD IDEA when you have no changes staged/cached that you actually want to commit.

As asked for by @??s???? an explanation can be found at https://golang.org/pkg/fmt/#Sprint. Related explanations can be found at https://stackoverflow.com/a/44027953/12817546 and at https://stackoverflow.com/a/42302709/12817546. Here is @Yuanbo's answer in full.

package main

import "fmt"

func main() {
    var data interface{} = 2
    str := fmt.Sprint(data)
    fmt.Println(str)
}

1. Go and Check if a user is created or not if no please create a user by opening a file in /apache-tomcat-9.0.20/tomcat-users.xml add a line into it

   <user username="tomcat" password="tomcat" roles="admin-gui,manager-gui,manager-script" />

2. Goto /apache-tomcat-9.0.20/webapps/manager/META-INF/ open context.xml comment everything in context tag example:

<Context antiResourceLocking="false" privileged="true" >
     <!--Valve className="org.apache.catalina.valves.RemoteAddrValve"
            allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /-->
   </Context>

You need to set the return value of setInterval to a variable within the scope of the click handler, then use clearInterval() like this:

var interval = null;
$(document).on('ready',function(){
    interval = setInterval(updateDiv,3000);
});

function updateDiv(){
    $.ajax({
        url: 'getContent.php',
        success: function(data){
            $('.square').html(data);
        },
        error: function(){
            clearInterval(interval); // stop the interval
            $.playSound('oneday.wav');
            $('.square').html('<span style="color:red">Connection problems</span>');
        }
    });
}

In JavaScript 1.8.5, Object.getOwnPropertyNames returns an array of all properties found directly upon a given object.

Object.getOwnPropertyNames ( obj )

and another method Object.keys, which returns an array containing the names of all of the given object's own enumerable properties.

Object.keys( obj )

I used forEach to list values and keys in obj, same as for (var key in obj) ..

Object.keys(obj).forEach(function (key) {
      console.log( key , obj[key] );
});

This all are new features in ECMAScript , the mothods getOwnPropertyNames, keys won't supports old browser's.

This error can also occur if you accidentally use = instead of IN in the WHERE clause:

FOR EXAMPLE:

WHERE product_id = (1,2,3);

If method 1 has to be executed after method 2, 3, 4. The following code snippet can be the solution for this using Deferred object in JavaScript.

function method1(){_x000D_
  var dfd = new $.Deferred();_x000D_
     setTimeout(function(){_x000D_
     console.log("Inside Method - 1"); _x000D_
     method2(dfd);  _x000D_
    }, 5000);_x000D_
  return dfd.promise();_x000D_
}_x000D_
_x000D_
function method2(dfd){_x000D_
  setTimeout(function(){_x000D_
   console.log("Inside Method - 2"); _x000D_
   method3(dfd); _x000D_
  }, 3000);_x000D_
}_x000D_
_x000D_
function method3(dfd){_x000D_
  setTimeout(function(){_x000D_
   console.log("Inside Method - 3");  _x000D_
   dfd.resolve();_x000D_
  }, 3000);_x000D_
}_x000D_
_x000D_
function method4(){   _x000D_
   console.log("Inside Method - 4");  _x000D_
}_x000D_
_x000D_
var call = method1();_x000D_
_x000D_
$.when(call).then(function(cb){_x000D_
  method4();_x000D_
});

Retry helper: a generic java implementation that contains both returnable and void type retries.

import java.util.function.Supplier;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class RetryHelper {
  private static final Logger log = LoggerFactory.getLogger(RetryHelper.class);
  private int retryWaitInMS;
  private int maxRetries;

  public RetryHelper() {
    this.retryWaitInMS = 300;
    this.maxRetries = 3;
  }

  public RetryHelper(int maxRetry) {
    this.maxRetries = maxRetry;
    this.retryWaitInMS = 300;
  }

  public RetryHelper(int retryWaitInSeconds, int maxRetry) {
    this.retryWaitInMS = retryWaitInSeconds;
    this.maxRetries = maxRetry;
  }

  public <T> T retryAndReturn(Supplier<T> supplier) {
    try {
      return supplier.get();
    } catch (Exception var3) {
      return this.retrySupplier(supplier);
    }
  }

  public void retry(Runnable runnable) {
    try {
      runnable.run();
    } catch (Exception var3) {
      this.retrySupplier(() -> {
        runnable.run();
        return null;
      });
    }

  }

  private <T> T retrySupplier(Supplier<T> supplier) {
    log.error("Failed <TASK>, will be retried " + this.maxRetries + " times.");
    int retryCounter = 0;

    while(retryCounter < this.maxRetries) {
      try {
        return supplier.get();
      } catch (Exception var6) {
        ++retryCounter;
        log.error("<TASK> failed on retry: " + retryCounter + " of " + this.maxRetries + " with error: " + var6.getMessage());
        if (retryCounter >= this.maxRetries) {
          log.error("Max retries exceeded.");
          throw var6;
        }

        try {
          Thread.sleep((long)this.retryWaitInMS);
        } catch (InterruptedException var5) {
          var5.printStackTrace();
        }
      }
    }

    return supplier.get();
  }

  public int getRetryWaitInMS() {
    return this.retryWaitInMS;
  }

  public int getMaxRetries() {
    return this.maxRetries;
  }
}

Usage:

    try {
      returnValue = new RetryHelper().retryAndReturn(() -> performSomeTask(args));
      //or no return type:
      new RetryHelper().retry(() -> mytask(args));
    } catch(Exception ex){
      log.error(e.getMessage());
      throw new CustomException();
    }

The problem is that /var/www doesn't exist either, and mkdir isn't recursive by default -- it expects the immediate parent directory to exist.

Use:

mkdir -p /var/www/app

...or install a package that creates a /var/www prior to reaching this point in your Dockerfile.

See query:

SELECT * FROM Table1 WHERE
id NOT IN (SELECT 
        e.id
    FROM
        Table1 e
            INNER JOIN
        Table2 s ON e.id = s.id);

Conceptually would be: Fetching the matching records in subquery and then in main query fetching the records which are not in subquery.

I had this edge case, where I checked out a previous version of the code in which my file directory structure was different:

git checkout 1.87.1                                    
warning: unable to unlink web/sites/default/default.settings.php: Permission denied
... other warnings ...
Note: checking out '1.87.1'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. 
Example:

  git checkout -b <new-branch-name>

HEAD is now at 50a7153d7... Merge branch 'hotfix/1.87.1'

In a case like this you may need to use --force (when you know that going back to the original branch and discarding changes is a safe thing to do).

git checkout master did not work:

$ git checkout master
error: The following untracked working tree files would be overwritten by checkout:
web/sites/default/default.settings.php
... other files ...

git checkout master --force (or git checkout master -f) worked:

git checkout master -f
Previous HEAD position was 50a7153d7... Merge branch 'hotfix/1.87.1'
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.

Just in case it helps someone, here's what caused this error for me: I needed a procedure to return json but I left out the for json path:

set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite 
            from CS_GEO G (nolock) 
                join @allids a on g.ID = a.[value] 
            where g.Worksite = @worksite)

When I tried to save the stored procedure, it threw the error. I fixed it by adding for json path to the code at the end of the procedure:

set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite 
            from CS_GEO G (nolock) 
                join @allids a on g.ID = a.[value] 
            where g.Worksite = @worksite for json path)

At first, the problem is because you did't put any parameter for mysqli_error. I can see that it has been solved based on the post here. Most probably, the next problem is cause by wrong file path for the included file.. .

Are you sure this code

$myConnection = mysqli_connect("$db_host","$db_username","$db_pass","$db_name") or die ("could not connect to mysql");

is in the 'scripts' folder and your main code file is on the same level as the script folder?

jQuery("#your_div_id").remove(); will completely remove the corresponding elements from the HTML DOM. So if you want to show the div on another event without a refresh, it will not be possible to retrieve the removed elements back unless you use AJAX.

jQuery("#your_div_id").toggle("slow"); will also could make unexpected results. As an Example when you select some element on your div which generates another div with a close button(which uses the same close functionality just as your previous div) it could make undesired behaviour.

So without using AJAX, a good solution for the close button would be as follows

HTML____________

<div id="your_div_id">
<span class="close_div" onclick="close_div(1)">&#10006</span>
</div>

JQUERY__________

function close_div(id) {
    if(id === 1) {
        jQuery("#your_div_id").hide();
    }
}

Now you can show the div, when another event occures as you wish... :-)

For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.
