I use this method because for some reason, none of the other solutions proposed actually worked for me. I promise I tried.

section {
   position: relative;
   border-top: 52px solid transparent; /* navbar height +2 */
   margin: -30px 0 0;
   -webkit-background-clip: padding-box;
   -moz-background-clip: padding;
   background-clip: padding-box;
}

section:before {
   content: "";
   position: absolute;
   top: -2px;
   left: 0;
   right: 0;
   border-top: 2px solid transparent;
}

Replace section by a class if you prefer.

• bootstrap version: 3.3.7

For those who do not believe me I kindly prepared a jsfiddle with the solution in it: SOLUTION

Give the #under a negative z-index, e.g. -1

This happens because the z-index property is ignored in position: static;, which happens to be the default value; so in the CSS code you wrote, z-index is 1 for both elements no matter how high you set it in #over.

By giving #under a negative value, it will be behind any z-index: 1; element, i.e. #over.

Diff between Finalize and Dispose methods in C#.

GC calls the finalize method to reclaim the unmanaged resources(such as file operarion, windows api, network connection, database connection) but time is not fixed when GC would call it. It is called implicitly by GC it means we do not have low level control on it.

Dispose Method: We have low level control on it as we call it from the code. we can reclaim the unmanaged resources whenever we feel it is not usable.We can achieve this by implementing IDisposal pattern.

I'm on Ubuntu 15.04. This seemed to work:

$ sudo pip3 install numpy

On RHEL this worked:

$ sudo python3 -m pip install numpy

You can also use the | operator to concatenate two sets (union in set theory):

>>> my_set = {1}
>>> my_set = my_set | {2}
>>> my_set
{1, 2}

Or a shorter form using |=:

>>> my_set = {1}
>>> my_set |= {2}
>>> my_set
{1, 2}

Note: In versions prior to Python 2.7, use set([...]) instead of {...}.

$statement = $this->sql->getSqlStringForSqlObject( HERE GOES Zend\Db\Sql\SelectSQL object );

echo "SQL statement: $statement";

Example:

$select = $this->sql->select();
...
$select->from(array( 'u' => 'users' ));
$select->join(...
$select->group('u.id');
...
$statement = $this->sql->getSqlStringForSqlObject($select);
echo $statement;

To add to Mosh Feu answer, if the tabs where created on the fly like in my case, you would use the following code

$(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {
    var tab = $(e.target);
    var contentId = tab.attr("href");

    //This check if the tab is active
    if (tab.parent().hasClass('active')) {
         console.log('the tab with the content id ' + contentId + ' is visible');
    } else {
         console.log('the tab with the content id ' + contentId + ' is NOT visible');
    }

});

I hope this helps someone

You can create temp stored procedures like:

create procedure #mytemp as
begin
   select getdate() into #mytemptable;
end

in an SQL script, but not functions. You could have the proc store it's result in a temp table though, then use that information later in the script ..

easy enough to use the unname() function:

data.frame <- unname(data.frame)

public void OnClick(View.v)
Button b1 = (Button) findViewById(R.id.playButton);
b1.setVisiblity(View.INVISIBLE);

Generator Function, Generator Object, Generator:

A Generator function is just like a regular function in Python but it contains one or more yield statements. Generator functions is a great tool to create Iterator objects as easy as possible. The Iterator object returend by generator function is also called Generator object or Generator.

In this example I have created a Generator function which returns a Generator object <generator object fib at 0x01342480>. Just like other iterators, Generator objects can be used in a for loop or with the built-in function next() which returns the next value from generator.

def fib(max):
    a, b = 0, 1
    for i in range(max):
        yield a
        a, b = b, a + b
print(fib(10))             #<generator object fib at 0x01342480>

for i in fib(10):
    print(i)               # 0 1 1 2 3 5 8 13 21 34


print(next(myfib))         #0
print(next(myfib))         #1
print(next(myfib))         #1
print(next(myfib))         #2

So a generator function is the easiest way to create an Iterator object.

Iterator:

Every generator object is an iterator but not vice versa. A custom iterator object can be created if its class implements __iter__ and __next__ method (also called iterator protocol).

However, it is much easier to use generators function to create iterators because they simplify their creation, but a custom Iterator gives you more freedom and you can also implement other methods according to your requirements as shown in the below example.

class Fib:
    def __init__(self,max):
        self.current=0
        self.next=1
        self.max=max
        self.count=0

    def __iter__(self):
        return self

    def __next__(self):
        if self.count>self.max:
            raise StopIteration
        else:
            self.current,self.next=self.next,(self.current+self.next)
            self.count+=1
            return self.next-self.current

    def __str__(self):
        return "Generator object"

itobj=Fib(4)
print(itobj)               #Generator object

for i in Fib(4):  
    print(i)               #0 1 1 2

print(next(itobj))         #0
print(next(itobj))         #1
print(next(itobj))         #1

Depending on where you are you can also use:

this["funcname"]();
self["funcname"]();
window["funcname"]();
top["funcname"]();
globalThis["funcname"]();

or, in nodejs

global["funcname"]()

Ted Hopp answered this quite nicely. I have been using res/raw for my opengl texture and shader files. I was thinking about moving them to an assets directory to provide a hierarchical organization.

This thread convinced me not to. First, because I like the use of a unique resource id. Second because it's very simple to use InputStream/openRawResource or BitmapFactory to read in the file. Third because it's very useful to be able to use in a portable library.

1. Download XAMPP
2. Run XAMPP server. Click on Start button in front of MY SQL. Now you can see that color is changed to green. Now, Click on Admin.The new browser window will be open. Copy the link from browser and paste to the Admin properties as shown in below. Set path in the admin properties of database connection. Click on OK. Now your database is connected. enter image description here

I tried changing the padding and margin and well as the width and height, and then finally found that if you just increase the scale it'll work:

input[type=checkbox] {
    transform: scale(1.5);
}

You can filter all characters from the string that are not printable using string.printable, like this:

>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'

string.printable on my machine contains:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c

EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:

''.join(filter(lambda x: x in printable, s))

I think this message is not about avoiding to use switch. Instead it wants you to check for hasOwnProperty. The background can be read here: https://stackoverflow.com/a/16735184/1374488

You can also use -match against a Regular expression. Ex:

if ($dbUserName -match ".{8}" )
{
    Write-Output " Please enter more than 8 characters "
    $dbUserName=read-host " Re-enter database user name"
}

Also if you're like me and like your curly braces to be in the same horizontal position for your code blocks, you can put that on a new line, since it's expecting a code block it will look on next line. In some commands where the first curly brace has to be in-line with your command, you can use a grave accent marker (`) to tell powershell to treat the next line as a continuation.

$( "#foo" ).slideUp( 300 ).delay( 5000 ).fadeIn( 400 );

The opensource framework Dynamitey has a static method that does late binding using DLR including cast conversion among others.

dynamic Cast(object obj, Type castTo){
    return Dynamic.InvokeConvert(obj, castTo, explict:true);
}

The advantage of this over a Cast<T> called using reflection, is that this will also work for any IDynamicMetaObjectProvider that has dynamic conversion operators, ie. TryConvert on DynamicObject.

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

Update: capability appears to have been removed by Apple on or around iOS 4

Just to expand on an earlier answer, something like this does it for me:

NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"];

Note: This retrieves the "Phone number" that was entered during the iPhone's iTunes activation and can be null or an incorrect value. It's NOT read from the SIM card.

At least that does in 2.1. There are a couple of other interesting keys in NSUserDefaults that may also not last. (This is in my app which uses a UIWebView)

WebKitJavaScriptCanOpenWindowsAutomatically
NSInterfaceStyle
TVOutStatus
WebKitDeveloperExtrasEnabledPreferenceKey

and so on.

Not sure what, if anything, the others do.

Your activity doesn't extend FragmentActivity from the support library, therefore the method is not present in the superclass

If you are targeting api 11 or above, you could use Activity.getFragmentManager instead.

You can still use sizeWithFont. but, in iOS >= 7.0 method cause crashing if the string contains leading and trailing spaces or end lines \n.

Trimming text before using it

label.text = [label.text stringByTrimmingCharactersInSet:
             [NSCharacterSet whitespaceAndNewlineCharacterSet]];

That's also may apply to sizeWithAttributes and [label sizeToFit].

also, whenever you have nsstringdrawingtextstorage message sent to deallocated instance in iOS 7.0 device it deals with this.

To be even more pedantic, the most python doc consistent answer would be:

mypath = os.path.join('c:', os.sep, 'sourcedir')

Since you also need os.sep for the posix root path:

mypath = os.path.join(os.sep, 'usr', 'lib')

Do not encrypt/decrypt passwords, that is a significant security vulnerability. HASH passwords, using a strong hash algorithm such as PBKDF2, bcrypt, scrypts, or Argon.

When the user sets their password, hash it, and store the hash (and salt).

When the user logs in, re-hash their provided password, and compare it to the hash in the database.

This is an old question, and there are many answers, most of which will be more or less helpful; however, there is one, very important and still relevant point, which none of the answers touch (providing, instead, different hacks to make build possible), and which, I think, in no way has a less importance.. on the contrary.

According to your log message, you are using Maven, which is a Project Management tool, firmly following the conventions, over configuration principle.

When Maven builds the project:

1. it expects your project to have a particular directory structure, so that it knows where to expect what. This is called a Maven's Standard Directory Layout;
2. during the build, it creates also proper directory structure and places files into corresponding locations/directories, and this, in compliance with the Sun Microsystems Directory Structure Standard for Java EE [web] applications.

You may incorporate many things, including maven plugins, changing/reconfiguring project root directory, etc., but better and easier is to follow the default conventions over configuration, according to which, (now is the answer to your problem) there is one simple step that can make your project work: Just place your web.xml under src\main\webapp\WEB-INF\ and try to build the project with mvn package.

The accepted answer here is problematic, because there is no guarantee that an image will have any sort of interactive shell. For example, the drone/drone image contains on a single command /drone, and it has an ENTRYPOINT as well, so this will fail:

$ docker run -it drone/drone sh
FATA[0000] DRONE_HOST is not properly configured        

And this will fail:

$ docker run --rm -it --entrypoint sh drone/drone
docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"sh\": executable file not found in $PATH".

This is not an uncommon configuration; many minimal images contain only the binaries necessary to support the target service. Fortunately, there are mechanisms for exploring an image filesystem that do not depend on the contents of the image. The easiest is probably the docker export command, which will export a container filesystem as a tar archive. So, start a container (it does not matter if it fails or not):

$ docker run -it drone/drone sh
FATA[0000] DRONE_HOST is not properly configured        

Then use docker export to export the filesystem to tar:

$ docker export $(docker ps -lq) | tar tf -

The docker ps -lq there means "give me the id of the most recent docker container". You could replace that with an explicit container name or id.

I have made it from fastboot mode (Phone - Xiomi Mi5 Android 6.0.1)

Here is steps:

# check if device available
fastboot devices
# remove user data
fastboot erase userdata
# remove cache
fastboot erase cache 
# reboot device
fastboot reboot

Regarding #2, according to the JSR-330 spec:

This package provides dependency injection annotations that enable portable classes, but it leaves external dependency configuration up to the injector implementation.

So it's up to the provider to determine which objects are available for injection. In the case of Spring it is all Spring beans. And any class annotated with JSR-330 annotations are automatically added as Spring beans when using an AnnotationConfigApplicationContext.

Variable interpolation does not happen in single quotes. You need to use double quotes as:

$i = 1
echo "<p class=\"paragraph$i\"></p>";
++i;

I was searching to solve the following error message:

unicodedecodeerror: 'ascii' codec can't decode byte 0xe2 in position 5454: ordinal not in range(128)

I finally got it fixed by specifying 'encoding':

f = open('../glove/glove.6B.100d.txt', encoding="utf-8")

Wish it could help you too.

You can use Jquery's on method and listen for the scroll event.

Try this:

#myelement {
  background-position: 100% 50%;
  margin-right: 5px;
}

Note though that the code above will move the whole element (not the background image only) 5px from the right. This might be ok for your case.

I am now able to successfully build. Not sure exactly which step "fixed" things, but this was the sequence:

• Tried automatic signing again. No go, so reverted to manual.
• After reverting, I had no Eligible Profiles, all were ineligible. Strange.
• I created a new certificate and profile, imported both. This too was "ineligible".
• Removed the iOS platform and re-added it. I had tried this previously without luck.
• After doing this, Xcode on its own defaulted to automatic signing. And this worked! Success!

While I am not sure exactly which parts were necessary, I think the previous certificates were the problem. I hate Xcode :(

Thanks for help.

If you already know the indices:

list1 = ['x','y','z','a','b','c','d','e','f','g']
indices = [(0, 4), (5, 9)]
print [list1[s:e+1] for s,e in indices]

Note that we're adding +1 to the end to make the range inclusive...

Your html is not updated every 15 seconds. The cause could be browser caching. Add Math.random() to avoid browser caching, and it's better to wait until the DOM is fully loaded as pointed out by @shadow. But I think the main cause is the caching

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<script type="text/javascript">
$(document).ready(function(){
    var auto_refresh = setInterval(
    function ()
    {
       $('.View').load('Small.php?' + Math.random()).fadeIn("slow");
    }, 15000); // refresh every 15000 milliseconds
});
</script>

I had the same Problem. This solution works for me.

The accepted answer is correct but I will rewrite complete steps for java.

I am currently using Swagger V2 with Spring Boot 2 and it's straightforward 3 step process.

Step 1: Add required dependencies in pom.xml file. The second dependency is optional use it only if you need Swagger UI.

        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

Step 2: Add configuration class

@Configuration
@EnableSwagger2
public class SwaggerConfig {

     public static final Contact DEFAULT_CONTACT = new Contact("Usama Amjad", "https://stackoverflow.com/users/4704510/usamaamjad", "[email protected]");
      public static final ApiInfo DEFAULT_API_INFO = new ApiInfo("Article API", "Article API documentation sample", "1.0", "urn:tos",
              DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList<VendorExtension>());

    @Bean
    public Docket api() {
        Set<String> producesAndConsumes = new HashSet<>();
        producesAndConsumes.add("application/json");
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(DEFAULT_API_INFO)
                .produces(producesAndConsumes)
                .consumes(producesAndConsumes);

    }
}

Step 3: Setup complete and now you need to document APIs in controllers

    @ApiOperation(value = "Returns a list Articles for a given Author", response = Article.class, responseContainer = "List")
    @ApiResponses(value = { @ApiResponse(code = 200, message = "Success"),
            @ApiResponse(code = 404, message = "The resource you were trying to reach is not found") })
    @GetMapping(path = "/articles/users/{userId}")
    public List<Article> getArticlesByUser() {
       // Do your code
    }

Usage:

You can access your Documentation from http://localhost:8080/v2/api-docs just copy it and paste in Postman to import collection.

Optional Swagger UI: You can also use standalone UI without any other rest client via http://localhost:8080/swagger-ui.html and it's pretty good, you can host your documentation without any hassle.

The css and js files are located within the package: bootstrap/docs/assets/

UPDATE:

since v3 there is a dist folder in the package that contains all css, js and fonts.

Another option (if you just want to fetch single files) might be: pulldown. Configuration is extremely simple and you can easily add your own files/urls to the list.

This sounds to me like what you have is one command with 2 outputs, I would opt for making the change in both client and server for this.

At the client, use JS to build up the URL you want to post to (use JQuery for simplicity) i.e.

<script type="text/javascript">
    $(function() {
        // this code detects a button click and sets an `option` attribute
        // in the form to be the `name` attribute of whichever button was clicked
        $('form input[type=submit]').click(function() {
            var $form = $('form');
            form.removeAttr('option');
            form.attr('option', $(this).attr('name'));
        });
        // this code updates the URL before the form is submitted
        $("form").submit(function(e) { 
            var option = $(this).attr("option");
            if (option) {
                e.preventDefault();
                var currentUrl = $(this).attr("action");
                $(this).attr('action', currentUrl + "/" + option).submit();     
            }
        });
    });
</script>
...
<input type="submit" ... />
<input type="submit" name="excel" ... />

Now at the server side we can add a new route to handle the excel request

routes.MapRoute(
    name: "ExcelExport",
    url: "SearchDisplay/Submit/excel",
    defaults: new
    {
        controller = "SearchDisplay",
        action = "SubmitExcel",
    });

You can setup 2 distinct actions

public ActionResult SubmitExcel(SearchCostPage model)
{
   ...
}

public ActionResult Submit(SearchCostPage model)
{
   ...
}

Or you can use the ActionName attribute as an alias

public ActionResult Submit(SearchCostPage model)
{
   ...
}

[ActionName("SubmitExcel")]
public ActionResult Submit(SearchCostPage model)
{
   ...
}

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.

FWIW, the encoding is not being lost. The encoding is used by the markup parser (browser) during the page load. Once the source is read and parsed and the browser has the DOM loaded into memory, the encoding has been parsed into what it represents. So by the time your JS is execute to read anything in memory, the char it gets is what the encoding represented.

I may be operating strictly on semantics here, but I wanted you to understand the purpose of encoding. The word "lost" makes it sound like something isn't working like it should.

I am trying to check if a key exist in an array in angular way and landed here on this question. In my Angularjs 1.4 ternary operator worked like below

{{ CONDITION ? TRUE : FALSE }}

hence for the array key exist i did a simple JS check

Solution 1 : {{ array['key'] !== undefined ? array['key'] : 'n/a' }}

Solution 2 : {{ "key" in array ? array['key'] : 'n/a' }}

The question would need more details.
Do you want just to look at a file (eg. a log file) or to edit it?
Do you have more memory than the size of the file you want to load or less?
For example, TheGun, a very small text editor written in assembly language, claims to "not have an effective file size limit and the maximum size that can be loaded into it is determined by available memory and loading speed of the file. [...] It has been speed optimised for both file load and save."

To abstract the memory limit, I suppose one can use mapped memory. But then, if you need to edit the file, some clever method should be used, like storing in memory the local changes, and applying them chunk by chunk when saving. Might be ineffective in some cases (big search/replace for example).

Offering an interactive sort handling multiple columns is nothing trivial.

Unless you want to write a good amount of code handling logic for multiple row clicks, editing and refreshing page content, managing sort algorithms for large tables… then you really are better off adopting a plug-in.

tablesorter, (with updates by Mottie) is my favorite. It’s easy to get going and very customizable. Just add the class tablesorter to the table you want to sort, then invoke the tablesorter plugin in a document load event:

$(function(){
    $("#myTable").tablesorter();
});

In docker image of PHP-FPM, i've see such approach:

# cat /usr/local/etc/php-fpm.d/docker.conf
[global]
error_log = /proc/self/fd/2

[www]
; if we send this to /proc/self/fd/1, it never appears
access.log = /proc/self/fd/2

Try this:

SELECT CONVERT(date, GETDATE())

ESC is the character _2_7, not _1_7. You can also try decimal 12 (aka. FF, form feed).

Note that all these special characters are not handled by the Arduino but by the program on the receiving side. So a standard Unix terminal (xterm, gnome-terminal, kterm, ...) handles a different set of control sequences then say a Windows terminal program like HTerm.

Therefore you should specify what program you are using exactly for display. After that it is possible to tell you what control characters and control sequences are usable.

var someParam = xxxxxxx;

commentbtn.click(function(){

    alert(someParam );
});

Per Byron's answer, you can't set networkaddress.cache.ttl or networkaddress.cache.negative.ttl as System Properties by using the -D flag or calling System.setProperty because these are not System properties - they are Security properties.

If you want to use a System property to trigger this behavior (so you can use the -D flag or call System.setProperty), you will want to set the following System property:

-Dsun.net.inetaddr.ttl=0

This system property will enable the desired effect.

But be aware: if you don't use the -D flag when starting the JVM process and elect to call this from code instead:

java.security.Security.setProperty("networkaddress.cache.ttl" , "0")

This code must execute before any other code in the JVM attempts to perform networking operations.

This is important because, for example, if you called Security.setProperty in a .war file and deployed that .war to Tomcat, this wouldn't work: Tomcat uses the Java networking stack to initialize itself much earlier than your .war's code is executed. Because of this 'race condition', it is usually more convenient to use the -D flag when starting the JVM process.

If you don't use -Dsun.net.inetaddr.ttl=0 or call Security.setProperty, you will need to edit $JRE_HOME/lib/security/java.security and set those security properties in that file, e.g.

networkaddress.cache.ttl = 0
networkaddress.cache.negative.ttl = 0

But pay attention to the security warnings in the comments surrounding those properties. Only do this if you are reasonably confident that you are not susceptible to DNS spoofing attacks.

With the release of TypeScript 3.7, optional chaining (the ? operator) is now officially available.

As such, you can simplify your expression to the following:

const data = change?.after?.data();

You may read more about it from that version's release notes, which cover other interesting features released on that version.

Run the following to install the latest stable release of TypeScript.

npm install typescript

That being said, Optional Chaining can be used alongside Nullish Coalescing to provide a fallback value when dealing with null or undefined values

const data = change?.after?.data() ?? someOtherData();

You could try my wkhtmltopdf wrapper: https://github.com/pruiz/WkHtmlToXSharp ;)

The steel is far from hot, but I combined @abatishchev's solution with the answer from this post and got to this result. Hope it's useful:

public static class GlobalVars
{
    private const string GlobalKey = "AllMyVars";

    static GlobalVars()
    {
        Hashtable table = HttpContext.Current.Application[GlobalKey] as Hashtable;

        if (table == null)
        {
            table = new Hashtable();
            HttpContext.Current.Application[GlobalKey] = table;
        }
    }

    public static Hashtable Vars
    {
        get { return HttpContext.Current.Application[GlobalKey] as Hashtable; }
    }

    public static IEnumerable<SomeClass> SomeCollection
    {
        get { return GetVar("SomeCollection") as IEnumerable<SomeClass>; }
        set { WriteVar("SomeCollection", value); }
    }

    internal static DateTime SomeDate
    {
        get { return (DateTime)GetVar("SomeDate"); }
        set { WriteVar("SomeDate", value); }
    }

    private static object GetVar(string varName)
    {
        if (Vars.ContainsKey(varName))
        {
            return Vars[varName];
        }

        return null;
    }

    private static void WriteVar(string varName, object value)
    {
        if (value == null)
        {
            if (Vars.ContainsKey(varName))
            {
                Vars.Remove(varName);
            }
            return;
        }

        if (Vars[varName] == null)
        {
            Vars.Add(varName, value);
        }
        else
        {
            Vars[varName] = value;
        }
    }

public class Journal : ApiController
{
    public MyResult Get(journal id)
    {
        return null;
    }
}

public class Journal : ApiController
{

    public MyResult Get(journal id, publication id)
    {
        return null;
    }
}

I am not sure whether overloading get/post method violates the concept of restfull api,but it workds. If anyone could've enlighten on this matter. What if I have a uri as

uri:/api/journal/journalid
uri:/api/journal/journalid/publicationid

so as you might seen my journal sort of aggregateroot, though i can define another controller for publication solely and pass id number of publication in my url however this gives much more sense. since my publication would not exist without journal itself.

Heap allocations are possible for static variables if you use the lazy_static macro as seen in the docs

Using this macro, it is possible to have statics that require code to be executed at runtime in order to be initialized. This includes anything requiring heap allocations, like vectors or hash maps, as well as anything that requires function calls to be computed.

// Declares a lazily evaluated constant HashMap. The HashMap will be evaluated once and
// stored behind a global static reference.

use lazy_static::lazy_static;
use std::collections::HashMap;

lazy_static! {
    static ref PRIVILEGES: HashMap<&'static str, Vec<&'static str>> = {
        let mut map = HashMap::new();
        map.insert("James", vec!["user", "admin"]);
        map.insert("Jim", vec!["user"]);
        map
    };
}

fn show_access(name: &str) {
    let access = PRIVILEGES.get(name);
    println!("{}: {:?}", name, access);
}

fn main() {
    let access = PRIVILEGES.get("James");
    println!("James: {:?}", access);

    show_access("Jim");
}

Because it's an integer. You need to declare them as floating point numbers or decimals, or cast to such in the calculation.

Robomongo's shell functionality will solve the problem. In my case I needed couple of columns as CSV format.

var cursor = db.getCollection('Member_details').find({Category: 'CUST'},{CustomerId :1,Name :1,_id:0})

while (cursor.hasNext()) {
    var record = cursor.next();   
    print(record.CustomerID + "," + record.Name)
}

Output : -------

334, Harison
433, Rechard
453, Michel
533, Pal

That is very odd.

I went through ItemNotFoundException's base classes and tested the following multiple catches to see what would catch it:

try {
  remove-item C:\nonexistent\file.txt -erroraction stop
}
catch [System.Management.Automation.ItemNotFoundException] {
  write-host 'ItemNotFound'
}
catch [System.Management.Automation.SessionStateException] {
  write-host 'SessionState'
}
catch [System.Management.Automation.RuntimeException] {
  write-host 'RuntimeException'
}
catch [System.SystemException] {
  write-host 'SystemException'
}
catch [System.Exception] {
  write-host 'Exception'
}
catch {
  write-host 'well, darn'
}

As it turns out, the output was 'RuntimeException'. I also tried it with a different exception CommandNotFoundException:

try {
  do-nonexistent-command
}
catch [System.Management.Automation.CommandNotFoundException] {
  write-host 'CommandNotFoundException'
}
catch {
  write-host 'well, darn'
}

That output 'CommandNotFoundException' correctly.

I vaguely remember reading elsewhere (though I couldn't find it again) of problems with this. In such cases where exception filtering didn't work correctly, they would catch the closest Type they could and then use a switch. The following just catches Exception instead of RuntimeException, but is the switch equivalent of my first example that checks all base types of ItemNotFoundException:

try {
  Remove-Item C:\nonexistent\file.txt -ErrorAction Stop
}
catch [System.Exception] {
  switch($_.Exception.GetType().FullName) {
    'System.Management.Automation.ItemNotFoundException' {
      write-host 'ItemNotFound'
    }
    'System.Management.Automation.SessionStateException' {
      write-host 'SessionState'
    }
    'System.Management.Automation.RuntimeException' {
      write-host 'RuntimeException'
    }
    'System.SystemException' {
      write-host 'SystemException'
    }
    'System.Exception' {
      write-host 'Exception'
    }
    default {'well, darn'}
  }
}

This writes 'ItemNotFound', as it should.

The statement "use strict"; instructs the browser to use the Strict mode, which is a reduced and safer feature set of JavaScript.

List of features (non-exhaustive)

1. Disallows global variables. (Catches missing var declarations and typos in variable names)

2. Silent failing assignments will throw error in strict mode (assigning NaN = 5;)

3. Attempts to delete undeletable properties will throw (delete Object.prototype)

4. Requires all property names in an object literal to be unique (var x = {x1: "1", x1: "2"})

5. Function parameter names must be unique (function sum (x, x) {...})

6. Forbids octal syntax (var x = 023; some devs assume wrongly that a preceding zero does nothing to change the number.)

7. Forbids the with keyword

8. eval in strict mode does not introduce new variables

9. Forbids deleting plain names (delete x;)

10. Forbids binding or assignment of the names eval and arguments in any form

11. Strict mode does not alias properties of the arguments object with the formal parameters. (i.e. in function sum (a,b) { return arguments[0] + b;} This works because arguments[0] is bound to a and so on. )

12. arguments.callee is not supported

Update since Java 8: Java 8 uses a self-balanced tree for collision-handling, improving the worst case from O(n) to O(log n) for lookup. The use of a self-balanced tree was introduced in Java 8 as an improvement over chaining (used until java 7), which uses a linked-list, and has a worst case of O(n) for lookup (as it needs to traverse the list)

To answer the second part of your question, insertion is done by mapping a given element to a given index in the underlying array of the hashmap, however, when a collision occurs, all elements must still be preserved (stored in a secondary data-structure, and not just replaced in the underlying array). This is usually done by making each array-component (slot) be a secondary datastructure (aka bucket), and the element is added to the bucket residing on the given array-index (if the key does not already exist in the bucket, in which case it is replaced).

During lookup, the key is hashed to it's corresponding array-index, and search is performed for an element matching the (exact) key in the given bucket. Because the bucket does not need to handle collisions (compares keys directly), this solves the problem of collisions, but does so at the cost of having to perform insertion and lookup on the secondary datastructure. The key point is that in a hashmap, both the key and the value is stored, and so even if the hash collides, keys are compared directly for equality (in the bucket), and thus can be uniquely identified in the bucket.

Collission-handling brings the worst-case performance of insertion and lookup from O(1) in the case of no collission-handling to O(n) for chaining (a linked-list is used as secondary datastructure) and O(log n) for self-balanced tree.

References:

Java 8 has come with the following improvements/changes of HashMap objects in case of high collisions.

• The alternative String hash function added in Java 7 has been removed.

• Buckets containing a large number of colliding keys will store their entries in a balanced tree instead of a linked list after certain threshold is reached.

Above changes ensure performance of O(log(n)) in worst case scenarios (https://www.nagarro.com/en/blog/post/24/performance-improvement-for-hashmap-in-java-8)

No, that's more or less what they're meant to do.

In C (and many other languages), you can insert hard-to-see/type characters using \ notation:

• \a is alert/bell
• \b is backspace/rubout
• \n is newline
• \r is carriage return (return to left margin)
• \t is tab

You can also specify the octal value of any character using \0nnn, or the hexadecimal value of any character with \xnn.

• EG: the ASCII value of _ is octal 137, hex 5f, so it can also be typed \0137 or \x5f, if your keyboard didn't have a _ key or something. This is more useful for control characters like NUL (\0) and ESC (\033)

As someone posted (then deleted their answer before I could +1 it), there are also some less-frequently-used ones:

• \f is a form feed/new page (eject page from printer)
• \v is a vertical tab (move down one line, on the same column)

On screens, \f usually works the same as \v, but on some printers/teletypes, it will go all the way to the next form/sheet of paper.

Eric's answer doesn't work when you're using "break" or "continue".

This can be fixed by rewriting the first line:

Original line (reformatted):

for (unsigned i = 0, __a = 1; i < B.size(); i++, __a = 1)

Fixed:

for (unsigned i = 0, __a = 1; __a && i < B.size(); i++, __a = 1)

If you compare it to Johannes' loop, you'll see that he's actually doing the same, just a bit more complicated and uglier.

I would approach this by using re.match in the following way:

import re
match = re.match(r"([a-z]+)([0-9]+)", 'foofo21', re.I)
if match:
    items = match.groups()
print(items)
>> ("foofo", "21")

I presume that this question is a continuation of this one.

What are you trying to do? Do you really want to dynamically change the text in your TextView objects when the user clicks a button? You can certainly do that, if you have a reason, but, if the text is static, it is usually set in the main.xml file, like this:

<TextView  
android:id="@+id/rate"
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/rate"
/>

The string "@string/rate" refers to an entry in your strings.xml file that looks like this:

<string name="rate">Rate</string>

If you really want to change this text later, you can do so by using Nikolay's example - you'd get a reference to the TextView by utilizing the id defined for it within main.xml, like this:

final TextView textViewToChange = (TextView) findViewById(R.id.rate);
textViewToChange.setText(
    "The new text that I'd like to display now that the user has pushed a button.");

Don't know the cause but I can contribute a quick and easy work around.

I just experienced this this oddity on CentOS 6 after cat > shScript.sh (paste, ^Z) then editing the file in KWrite. Oddly there was no discernible instance (ps -ef) of the script executing.

My quick work around was simply to cp shScript.sh shScript2.sh then I was able to execute shScript2.sh. Then I deleted both. Done!

With Java 8 lambda expression you can do something like

cats.stream()
    .filter( c -> c.getAge() == 3 && c.getFavoriteFood() == WHISKAS )
    .collect(Collectors.toList());

Conceptually the same as the Guava Predicate approach, but it looks much cleaner with lambda

Probably not a valid answer for OP but worth to note for people with similar need. :)

Make both divs like this. This will align both divs side-by-side.

.my-class {
  display : inline-flex;
} 

:set paste is your friend I use putty and end up copying code between windows. Before I was turned on to :set paste (and :set nopaste) copy/paste gave me fits for that very reason.

Go into your application directory on terminal and run following command:

heroku restart

echo "body" | mail -S [email protected] "Hello"

-S lets you specify lots of string options, by far the easiest way to modify headers and such.

You can use trim function from php to trim both sides (left and right)

 trim($yourinputdata," ");

Or

trim($yourinputdata);

You can also use

ltrim() - Removes whitespace or other predefined characters from the left side of a string
rtrim() - Removes whitespace or other predefined characters from the right side of a string

System: PHP 4,5,7
Docs: http://php.net/manual/en/function.trim.php

You should use fm element to delete blank spaces.

SELECT TO_CHAR(sysdate, 'fmDAY DD "de" MONTH "de" YYYY') CURRENT_DATE
FROM   dual;

its because you probaly installed wamp server and uninstall it but wampmysql.exe still running and using the default mysql port go to msconfig under services tab uncheck wampmysqld to deactivate it reboot the computer should work

Quite a while later, and thanks to @arne, I created this similar small function to handle where the input should be disabled AND hidden, or enabled AND shown:

function toggleInputState(el, on) {
  // 'on' = true(visible) or false(hidden)
  // If a field is to be shown, enable it; if hidden, disable it.
  // Disabling will prevent the field's value from being submitted
  $(el).prop('disabled', !on).toggle(on);
}

Then a jQuery object (such as $('input[name="something"]') ) is simply switched using:

toggleInputState(myElement, myBoolean)

use curl php library: http://php.net/manual/en/book.curl.php

direct example: CURL_EXEC:

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

Sounds like you executed another statement in the same connection before traversing the result set from the first statement. If you're nesting the processing of two result sets from the same database, you're doing something wrong. The combination of those sets should be done on the database side.

$("#foo > div").length

Direct children of the element with the id 'foo' which are divs. Then retrieving the size of the wrapped set produced.

Building off of Viktar's answer, here's an implementation you can call once on a given hidden input element to ensure that subsequent change events get fired whenever the value of the input element changes:

/**
 * Modifies the provided hidden input so value changes to trigger events.
 *
 * After this method is called, any changes to the 'value' property of the
 * specified input will trigger a 'change' event, just like would happen
 * if the input was a text field.
 *
 * As explained in the following SO post, hidden inputs don't normally
 * trigger on-change events because the 'blur' event is responsible for
 * triggering a change event, and hidden inputs aren't focusable by virtue
 * of being hidden elements:
 * https://stackoverflow.com/a/17695525/4342230
 *
 * @param {HTMLInputElement} inputElement
 *   The DOM element for the hidden input element.
 */
function setupHiddenInputChangeListener(inputElement) {
  const propertyName = 'value';

  const {get: originalGetter, set: originalSetter} =
    findPropertyDescriptor(inputElement, propertyName);

  // We wrap this in a function factory to bind the getter and setter values
  // so later callbacks refer to the correct object, in case we use this
  // method on more than one hidden input element.
  const newPropertyDescriptor = ((_originalGetter, _originalSetter) => {
    return {
      set: function(value) {
        const currentValue = originalGetter.call(inputElement);

        // Only fire change if the value actually changed.
        if (currentValue !== value) {
          inputElement.dispatchEvent(new Event('change'));
        }
      },

If the 2nd company is happy for you to access their content in an IFrame then they need to take the restriction off - they can do this fairly easily in the IIS config.

There's nothing you can do to circumvent it and anything that does work should get patched quickly in a security hotfix. You can't tell the browser to just render the frame if the source content header says not allowed in frames. That would make it easier for session hijacking.

If the content is GET only you don't post data back then you could get the page server side and proxy the content without the header, but then any post back should get invalidated.

You should use the excellent OpenCSV for reading and writing CSV files. To adapt your example to use the library it would look like this:

public class ParseCSV {
  public static void main(String[] args) {
    try {
      //csv file containing data
      String strFile = "C:/Users/rsaluja/CMS_Evaluation/Drupal_12_08_27.csv";
      CSVReader reader = new CSVReader(new FileReader(strFile));
      String [] nextLine;
      int lineNumber = 0;
      while ((nextLine = reader.readNext()) != null) {
        lineNumber++;
        System.out.println("Line # " + lineNumber);

        // nextLine[] is an array of values from the line
        System.out.println(nextLine[4] + "etc...");
      }
    }
  }
}

Theseus is a project by Adobe research which lets you debug your Node.js code in their Open Source editor Brackets. It has some interesting features like real-time code coverage, retroactive inspection, asynchronous call tree.

Simply use this to get date before 300 days, replace 300 with your days:

Date date = new Date(); // Or where ever you get it from
Date daysAgo = new DateTime(date).minusDays(300).toDate();

Here,

DateTime is org.joda.time.DateTime;

Date is java.util.Date

A nice way is to use Spring's ResponseStatusException

Rather than returning a ResponseEntityor similar you simply throw the ResponseStatusException from the controller with an HttpStatus and cause, for example:

throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Cause description here");

or:

throw new ResponseStatusException(HttpStatus.INTERNAL_SERVER_ERROR, "Cause description here");

This results in a response to the client containing the HTTP status (e.g. 400 Bad request) with a body like:

{
  "timestamp": "2020-07-09T04:43:04.695+0000",

You can do it without jQuery!

Example:

document.querySelector('button').setAttribute('disabled', '');

<button>My disabled button!</button>

To set the value of a Boolean attribute, such as disabled, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true. The absence of the attribute means its value is false. By setting the value of the disabled attribute to the empty string (""), we are setting disabled to true, which results in the button being disabled.

Most of these packages are relying on the reflect package to make such things possible.

fmt.Sprintf() is using -> func (p *pp) printArg(arg interface{}, verb rune) of standard lib

Go to line 638 -> https://golang.org/src/fmt/print.go

Here's what worked for me. I had to add a margin-bottom so the footer wouldn't eat up my content:

header {
  height: 20px;
  background-color: #1d0d0a;
  position: fixed;
  top: 0;
  width: 100%;
  overflow: hide;
}

content {
  margin-left: auto;
  margin-right: auto;
  margin-bottom: 100px;
  margin-top: 20px;
  overflow: auto;
  width: 80%;
}

footer {
  position: fixed;
  bottom: 0px;
  overflow: hide;
  width: 100%;
}

You can create a new writeable instance of HttpValueCollection by calling System.Web.HttpUtility.ParseQueryString(string.Empty), and then use it as any NameValueCollection. Once you have added the values you want, you can call ToString on the collection to get a query string, as follows:

NameValueCollection queryString = System.Web.HttpUtility.ParseQueryString(string.Empty);

queryString.Add("key1", "value1");
queryString.Add("key2", "value2");

return queryString.ToString(); // Returns "key1=value1&key2=value2", all URL-encoded

The HttpValueCollection is internal and so you cannot directly construct an instance. However, once you obtain an instance you can use it like any other NameValueCollection. Since the actual object you are working with is an HttpValueCollection, calling ToString method will call the overridden method on HttpValueCollection, which formats the collection as a URL-encoded query string.

After searching SO and the web for an answer to a similar issue, this is the most simple solution I could find.

.NET Core

If you're working in .NET Core, you can use the Microsoft.AspNetCore.WebUtilities.QueryHelpers class, which simplifies this greatly.

https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.webutilities.queryhelpers

Sample Code:

const string url = "https://customer-information.azure-api.net/customers/search/taxnbr";
var param = new Dictionary<string, string>() { { "CIKey", "123456789" } };

var newUrl = new Uri(QueryHelpers.AddQueryString(url, param));

if you testing some javascript requests for ionic2 or angularjs 2 , in your chrome on pc or mac , then be sure that you install CORS plugin for chrome browser to allow cross origin .

mayba get requests will work without needing that , but post and puts and delete will need you to install cors plugin for testing to go without problems , that definitley not cool , but i do not know how people do it without CORS plugin .

and also be sure the json response is not returning 400 by some json status

At least for me, there was an easy answer (after much digging around) to changing a tab title at runtime:

TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs); tabLayout.getTabAt(MyTabPos).setText("My New Text");

Same issue with mine.

New to Flutter. I'm using VS build-in terminal to do flutter run, to run the app in iPhone. It gives me error Error when reading 'lib/student_model.dart': No such file..., which is an old code version in my code. I have changed it to lib/model/student_model.dart.

And I search this line 'lib/student_model.dart'in the project, it appears filekernel_snapshot.d` containing it. So, it build the project with old code version.

For me, Flutter clean is not working. Restart VS fix the issue, not sure the problem is due to Flutter or VS?

And I'm wondering if there is some command to just build flutter project without run?

There are lots of free tools that can do this.

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

I solved this by going into Site Manager -> selected the connection that Failed to retrieve directory listing -> Switched to tab "Transfer Settings" and set "Transfer Mode" to "Active" instead of "Default". Also check if you are connected via VPN or anything similar, this can also interfere.

First of all, go to String.xml file

you can add any HTML attributes like , italic or bold or underline here.

    <resources>
        <string name="your_string_here">This is an <u>underline</u>.</string>
    </resources>

If you just want to print user name on the pages, maybe you'll like this solution. It's free from object castings and works without Spring Security too:

@RequestMapping(value = "/index.html", method = RequestMethod.GET)
public ModelAndView indexView(HttpServletRequest request) {

    ModelAndView mv = new ModelAndView("index");

    String userName = "not logged in"; // Any default user  name
    Principal principal = request.getUserPrincipal();
    if (principal != null) {
        userName = principal.getName();
    }

    mv.addObject("username", userName);

    // By adding a little code (same way) you can check if user has any
    // roles you need, for example:

    boolean fAdmin = request.isUserInRole("ROLE_ADMIN");
    mv.addObject("isAdmin", fAdmin);

    return mv;
}

Note "HttpServletRequest request" parameter added.

Works fine because Spring injects it's own objects (wrappers) for HttpServletRequest, Principal etc., so you can use standard java methods to retrieve user information.

May be useful for java and jstl.

1. Initialize variable with localized message.
2. After that it is possible to use it in jstl toLowerCase function.
3. Transform with CSS.

In JSP

1.

<fmt:message key="some.key" var="item"/>

2.

<div class="content">
  <a href="#">${fn:toLowerCase(item)}</a>
</div>

In CSS

3.

.content {
  text-transform:capitalize;
}

If you are using Talend MDM Server, the login is: login: admin password: talend

See more: http://wiki.glitchdata.com/index.php?title=TOS:_Accessing_the_Talend_MDM_Server

This differs from the default JBoss login of admin/admin The password setup file is also login-config.xml in this case.

Best solution

open XAMPP control panel,click on config for Apache, then click on Apache(httpd.config).now in the text editor . ctrl+f --> find "Listen 80" and replace it with "Listen 8079" wtihout the quotations :) but now you have to use it like this http://localhost:8079/

P.S, I tried to change port settings for skype , stopping the Web Deployment Agent Service which I could not find in windows 10,cmd--> net stop http, and other methods but nothing worked except this .

you could also do it this way, in my case i use it before and after an h1 (brute force it ehehehe)

.titleImage::before {
content: "--------";
letter-spacing: -3px;
}

.titreImage::after {
content: "--------";
letter-spacing: -3px;
}

If the letter spacing makes it so the line get in the text just use a margin to push it away!

If your dates column does not contain time information, you could get away with:

WHERE dates BETWEEN '20121211' and '20121213'

However, given your dates column is actually datetime, you want this

WHERE dates >= '20121211'
  AND dates < '20121214'  -- i.e. 00:00 of the next day

Another option for SQL Server 2008 onwards that retains SARGability (ability to use index for good performance) is:

WHERE CAST(dates as date) BETWEEN '20121211' and '20121213'

Note: always use ISO-8601 format YYYYMMDD with SQL Server for unambiguous date literals.

Simple and Complete Solution working for me. Supports ASP.NET MVC 4 and 5 (Supports ASP.NET 4.0, 4.5, and 4.5.1)

Step 1: Install NuGet Package by "Install-Package reCAPTCH.MVC"

Step 2: Add your Public and Private key to your web.config file in appsettings section

<appSettings>
    <add key="ReCaptchaPrivateKey" value=" -- PRIVATE_KEY -- " />
    <add key="ReCaptchaPublicKey" value=" -- PUBLIC KEY -- " />
</appSettings>  

You can create an API key pair for your site at https://www.google.com/recaptcha/intro/index.html and click on Get reCAPTCHA at top of the page

Step 3: Modify your form to include reCaptcha

@using reCAPTCHA.MVC
@using (Html.BeginForm())
{
    @Html.Recaptcha()
    @Html.ValidationMessage("ReCaptcha")
    <input type="submit" value="Register" />
}

Step 4: Implement the Controller Action that will handle the form submission and Captcha validation

[CaptchaValidator(
PrivateKey = "your private reCaptcha Google Key",
ErrorMessage = "Invalid input captcha.",
RequiredMessage = "The captcha field is required.")]
public ActionResult MyAction(myVM model)
{
    if (ModelState.IsValid) //this will take care of captcha
    {
    }
}

OR

public ActionResult MyAction(myVM model, bool captchaValid)
{
    if (captchaValid) //manually check for captchaValid 
    {
    }
}

You should use the arc4random_uniform() function. It uses a superior algorithm to rand. You don't even need to set a seed.

#include <stdlib.h>
// ...
// ...
int r = arc4random_uniform(74);

The arc4random man page:

NAME
     arc4random, arc4random_stir, arc4random_addrandom -- arc4 random number generator

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     u_int32_t
     arc4random(void);

     void
     arc4random_stir(void);

     void
     arc4random_addrandom(unsigned char *dat, int datlen);

DESCRIPTION
     The arc4random() function uses the key stream generator employed by the arc4 cipher, which uses 8*8 8
     bit S-Boxes.  The S-Boxes can be in about (2**1700) states.  The arc4random() function returns pseudo-
     random numbers in the range of 0 to (2**32)-1, and therefore has twice the range of rand(3) and
     random(3).

     The arc4random_stir() function reads data from /dev/urandom and uses it to permute the S-Boxes via
     arc4random_addrandom().

     There is no need to call arc4random_stir() before using arc4random(), since arc4random() automatically
     initializes itself.

EXAMPLES
     The following produces a drop-in replacement for the traditional rand() and random() functions using
     arc4random():

           #define foo4random() (arc4random() % ((unsigned)RAND_MAX + 1))

We can use the new DataFrameRDD for reading and writing the CSV data. There are few advantages of DataFrameRDD over NormalRDD:

1. DataFrameRDD are bit more faster than NormalRDD since we determine the schema and which helps to optimize a lot on runtime and provide us with significant performance gain.
2. Even if the column shifts in CSV it will automatically take the correct column as we are not hard coding the column number which was present in reading the data as textFile and then splitting it and then using the number of column to get the data.
3. In few lines of code you can read the CSV file directly.

You will be required to have this library: Add it in build.sbt

libraryDependencies += "com.databricks" % "spark-csv_2.10" % "1.2.0"

Spark Scala code for it:

val sc = new SparkContext(conf)
val sqlContext = new SQLContext(sc)
val csvInPath = "/path/to/csv/abc.csv"
val df = sqlContext.read.format("com.databricks.spark.csv").option("header","true").load(csvInPath)
//format is for specifying the type of file you are reading
//header = true indicates that the first line is header in it

To convert to normal RDD by taking some of the columns from it and

val rddData = df.map(x=>Row(x.getAs("colA")))
//Do other RDD operation on it

Saving the RDD to CSV format:

val aDf = sqlContext.createDataFrame(rddData,StructType(Array(StructField("colANew",StringType,true))))
aDF.write.format("com.databricks.spark.csv").option("header","true").save("/csvOutPath/aCSVOp")

Since the header is set to true we will be getting the header name in all the output files.

Short answer: you want to set the handler to a function:

elemm.onclick = function() { alert('blah'); };

Slightly longer answer: you'll have to write a few more lines of code to get that to work consistently across browsers.

The fact is that even the sligthly-longer-code that might solve that particular problem across a set of common browsers will still come with problems of its own. So if you don't care about cross-browser support, go with the totally short one. If you care about it and absolutely only want to get this one single thing working, go with a combination of addEventListener and attachEvent. If you want to be able to extensively create objects and add and remove event listeners throughout your code, and want that to work across browsers, you definitely want to delegate that responsibility to a library such as jQuery.

Const: Absolute constant value during the application life time.

Readonly: It can be changed in running time.

Just ran into this issue too, on an App that had to be compatible with Gingerbread and still retain as much of the styling from Holo-enabled devices as possible.

I found a relatively clean solution, that worked OK for me.

In the theme I use a 9-patch drawable background to get a custom background color:

<style name="Theme.Styled" parent="Theme.Sherlock">
   ...
   <item name="android:panelFullBackground">@drawable/menu_hardkey_panel</item>
</style>

I gave up trying to style the text color, and just used a Spannable to set the text color for my item in code:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
   MenuInflater inflater = getSupportMenuInflater();
   inflater.inflate(R.menu.actions_main, menu);

   if (android.os.Build.VERSION.SDK_INT < 
        android.os.Build.VERSION_CODES.HONEYCOMB) {

        SpannableStringBuilder text = new SpannableStringBuilder();
        text.append(getString(R.string.action_text));
        text.setSpan(new ForegroundColorSpan(Color.WHITE), 
                0, text.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        MenuItem item1 = menu.findItem(R.id.action_item1);
        item1.setTitle(text);
   }

   return true;
}

UPDATE Table
SET DateColumn=GETDATE()
WHERE UserID=@UserID

If you're inserting into a table, and will always need to put the current date, I would recommend setting GETDATE() as the default value for that column, and don't allow NULLs

Well, from sourceTree I couldn't resolve this issue but I created sshkey from bash and at least it works from git-bash.

The short answer is for creating an attribute in c# you only need to inherit it from Attribute class, Just this :)

But here I'm going to explain attributes in detail:

basically attributes are classes that we can use them for applying our logic to assemblies, classes, methods, properties, fields, ...

In .Net, Microsoft has provided some predefined Attributes like Obsolete or Validation Attributes like ( [Required], [StringLength(100)], [Range(0, 999.99)]), also we have kind of attributes like ActionFilters in asp.net that can be very useful for applying our desired logic to our codes (read this article about action filters if you are passionate to learn it)

one another point, you can apply a kind of configuration on your attribute via AttibuteUsage.

  [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]

When you decorate an attribute class with AttributeUsage you can tell to c# compiler where I'm going to use this attribute: I'm going to use this on classes, on assemblies on properties or on ... and my attribute is allowed to use several times on defined targets(classes, assemblies, properties,...) or not?!

After this definition about attributes I'm going to show you an example: Imagine we want to define a new lesson in university and we want to allow just admins and masters in our university to define a new Lesson, Ok?

namespace ConsoleApp1
{
    /// <summary>
    /// All Roles in our scenario
    /// </summary>
    public enum UniversityRoles
    {
        Admin,
        Master,
        Employee,
        Student
    }

    /// <summary>
    /// This attribute will check the Max Length of Properties/fields
    /// </summary>
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]

In the real world of programming maybe we don't use this approach for using attributes and I said this because of its educational point in using attributes

I encountered a similar issue just recently on our build server.

I copied the 7.0A folder (C:\Program Files\Microsoft SDKs\Windows\7.0A) from my computer (which has VS2010 installed) on it to the build server in the same location.

After create the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A. Set InstallationFolder to C:\Program Files\Microsoft SDKs\Windows\7.0A.

You can also reference the registry on your machine with VS2010 already installed on it if you are confused about what to do with the registry on the build server.

This could be because of wrong configuration, esp if your other sites are working fine.

<VirtualHost cmsdemo.git:88>
    DocumentRoot "C:/Projects/rwp/"
    ServerName cmsdemo.git
    <Directory C:/Projects/cmsdemo/>
        Require all granted 
        AllowOverride All
    </Directory>
</VirtualHost>

Notice in DocumentRoot I am specifying one folder and in Directory, I am specifying another hence 403 Error. This fixed my problem.

I recently had a similar issue, overlay2 grew bigger and bigger, But I couldn’t figure out what consumed the bulk of the space.

df showed me that overlay2 was about 24GB in size.

With du I tried to figure out what occupied the space… and failed.

The difference came from the fact that deleted files (mostly log files in my case) where still being used by a process (Docker). Thus the file doesn’t show up with du but the space it occupies will show with df.

A reboot of the host machine helped. Restarting the docker container would probably have helped already… This article on linuxquestions.org helped me to figure that out.

I have a Ryzen 2600X and I am able to run the emulator without problems. Here are the tweaks I made:

*NOTE: You don't need the beta version of Android Studio or Android Emulator.

1. Go to the MB bios and turn SVM on (CPU Virtualization).
2. In Windows right click Windows Button => Select "Apps and Features" => "Programs and features" => "Turn Windows Features on and off"
3. In the displayed list select Hyper-V checkbox == Make sure the subfolders are all selected. When prompted to restart, restart the PC.
4. After restart and update instalation screen you are back in Windows and you should be able to run the Emulator.

**Note: I have selected x86_64 and plain x86 images(both API 28) from the x86 Images tab and they work just fine.

***Note: Might also check for Android Licenses if errors pop up, I had an issue because of this while using Flutter, maybe it's related to that.

Usually a null pointer (which can be of any type, including a void pointer !) points to:

• the address 0, against which most CPU instructions sets can do a very fast compare-and-branch (to check for uninitialized or invalid pointers, for instance) with optimal code size/performance for the ISA.

• an address that's illegal for user code to access (such as 0x00000000 in many cases), so that if a code actually tries to access data at or near this address, the OS or debugger can easily stop or trap a program with this bug.

A void pointer is usually a method of cheating or turning-off compiler type checking, for instance if you want to return a pointer to one type, or an unknown type, to use as another type. For instance malloc() returns a void pointer to a type-less chunk of memory, the type of which you can cast to later use as a pointer to bytes, short ints, double floats, typePotato's, or whatever.

This is really old issue, but I just had similar problem. I was doing something like this :

// entity
$entityOne = $this->em->find(Parent::class, 1);

// do something on other entites (SomeEntityClass)
$this->em->persist($entity);
$this->em->flush();
$this->em->clear();

// and at end I was trying to save changes to first one by
$this->em->persist($entityOne);
$this->em->flush();
$this->em->clear();

Problem was that clear detach all entities including the first one and throw error The EntityManager is closed.

In my case solution was to just do clear on distinct type of Entity and leave $entityOne still under EM:

$this->em->clear(SomeEntityClass::class);

Using Visual Studio 2015 adding the additional parameter

/deployonbuild=false

to the msbuild command line fixed the issue.

Just use the formula

120 = (HOUR(A8)*3600+MINUTE(A8)*60+SECOND(A8))/60

As it may happens that the default branch of your submodules are not master (which happens a lot in my case), this is how I automate the full Git submodules upgrades:

git submodule init
git submodule update
git submodule foreach 'git fetch origin; git checkout $(git rev-parse --abbrev-ref HEAD); git reset --hard origin/$(git rev-parse --abbrev-ref HEAD); git submodule update --recursive; git clean -dfx'

The working solution listed are great, but the problem occurs when you want multiple default home for your git-bash.

A simple workaround is to start git-bash using bat script.

git-bash-to-htdocs.bat

cd C:\xampp\htdocs
"C:\Program Files\Git\git-bash.exe" 

The above of course assume git-bash is installed at C:\Program Files\Git\git-bash.exe

You can create multiple .bat file so your git-bash can start where it want to be

Try:

def (value1, value2) = '1128-2'.tokenize( '-' )

This line

mnuActionLanguage.ComboBox.DisplayMember = "Lang.Language";

is wrong. Change it to

mnuActionLanguage.ComboBox.DisplayMember = "Language";

and it will work (even without DataBind()).

Not a php pro. but i recently ran into this wall too and this is what i came up with.

function tag_contents($string, $tag_open, $tag_close){
   foreach (explode($tag_open, $string) as $key => $value) {
       if(strpos($value, $tag_close) !== FALSE){
            $result[] = substr($value, 0, strpos($value, $tag_close));;
       }
   }
   return $result;
}

$string = "i love cute animals, like [animal]cat[/animal],
           [animal]dog[/animal] and [animal]panda[/animal]!!!";

echo "<pre>";
print_r(tag_contents($string , "[animal]" , "[/animal]"));
echo "</pre>";

//result
Array
(
    [0] => cat
    [1] => dog
    [2] => panda
)

Tensorflow 2.0 Compatible Answer: The explanations of dga and stackoverflowuser2010 are very detailed about Logits and the related Functions.

All those functions, when used in Tensorflow 1.x will work fine, but if you migrate your code from 1.x (1.14, 1.15, etc) to 2.x (2.0, 2.1, etc..), using those functions result in error.

Hence, specifying the 2.0 Compatible Calls for all the functions, we discussed above, if we migrate from 1.x to 2.x, for the benefit of the community.

Functions in 1.x:

1. tf.nn.softmax
2. tf.nn.softmax_cross_entropy_with_logits
3. tf.nn.sparse_softmax_cross_entropy_with_logits

Respective Functions when Migrated from 1.x to 2.x:

1. tf.compat.v2.nn.softmax
2. tf.compat.v2.nn.softmax_cross_entropy_with_logits
3. tf.compat.v2.nn.sparse_softmax_cross_entropy_with_logits

For more information about migration from 1.x to 2.x, please refer this Migration Guide.

With the v3 API, you can easily close the InfoWindow with the InfoWindow.close() method. You simply need to keep a reference to the InfoWindow object that you are using. Consider the following example, which opens up an InfoWindow and closes it after 5 seconds:

<!DOCTYPE html>
<html> 
<head> 
  <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
  <title>Google Maps API InfoWindow Demo</title> 
  <script src="http://maps.google.com/maps/api/js?sensor=false" 
          type="text/javascript"></script>
</head> 
<body>
  <div id="map" style="width: 400px; height: 500px;"></div>

  <script type="text/javascript">
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 4,
      center: new google.maps.LatLng(-25.36388, 131.04492),
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    var marker = new google.maps.Marker({
      position: map.getCenter(),
      map: map
    });

    var infowindow = new google.maps.InfoWindow({
      content: 'An InfoWindow'
    });

    infowindow.open(map, marker);

    setTimeout(function () { infowindow.close(); }, 5000);
  </script>
</body>
</html>

If you have a separate InfoWindow object for each Marker, you may want to consider adding the InfoWindow object as a property of your Marker objects:

var marker = new google.maps.Marker({
  position: map.getCenter(),
   map: map
});

marker.infowindow = new google.maps.InfoWindow({
  content: 'An InfoWindow'
});

Then you would be able to open and close that InfoWindow as follows:

marker.infowindow.open(map, marker);
marker.infowindow.close();

The same applies if you have an array of markers:

var markers = [];

marker[0] = new google.maps.Marker({
  position: map.getCenter(),
   map: map
});

marker[0].infowindow = new google.maps.InfoWindow({
  content: 'An InfoWindow'
});

// ...

marker[0].infowindow.open(map, marker);
marker[0].infowindow.close();

I add an answer because I think a one line solution is always good! Atop of your myRscript.R file, add the following line:

eval(parse(text=paste(commandArgs(trailingOnly = TRUE), collapse=";")))

Then submit your script with something like:

R CMD BATCH [options] '--args arguments you want to supply' myRscript.R &

For example:

R CMD BATCH --vanilla '--args N=1 l=list(a=2, b="test") name="aname"' myscript.R &

Then:

> ls()
[1] "N"    "l"    "name"

As this answer says, you can also just wrap your code in an anonymous function like this:

expect(function(){
    model.get('z');
}).to.throw('Property does not exist in model schema.');

Write this below line after script tag start.

previous_Window=null;

It will work 100%. by using this code

 radius= circle.getRadius()/1000;
 radius_mile= circle.getRadius()/1609.344;

 newRadious = 'This Circle Radius Covers Approx ' + radius.toFixed(1) + ' Km'+' <br> This circle Radius Covers Approx '+ radius_mile.toFixed(1)+ 'Miles';
            var infoWindow= new google.maps.InfoWindow({
              content: newRadious
              });
 infoWindow.setContent(newRadious)
 infoWindow.setPosition(circle.getCenter());
 if (previous_Window) 
  previous_Window.close();

  infoWindow.open(map);
  previous_Window=infoWindow;

If your certificate is not installed locally. Or you tried running the certificate and opted to "revoke and request" a new certificate then you have the option to do that on the machine you are trying to run on

go to Preferences-> Accounts-> under your AppleId -> View Details -> under signing identities you can see the status of your certificate "Valid" or "Revoked" if revoked and you want to request a new one go to the -> + then -> the type of distribution you are trying to use.

I got similar problem when default SSL protocol for sending emails was set to TLSv1 and smtp server was not supporting this protocol anymore. Trick was to use newer protocol:

mail.smtp.ssl.protocols=TLSv1.2

dict1 = {}

dict1['dict2'] = {}

print dict1

>>> {'dict2': {},}

this is commonly known as nesting iterators into other iterators I think

Map<String, String> nodeMap = 
    new TreeMap<>(String.CASE_INSENSITIVE_ORDER);

That's really all you need.

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

# -u    The SVN URL to clone
# -l    The limit of revisions

./svn-lookback.sh -u https://server/project/trunk -l 5     

On French keyboard the default binding is : Ctrl+Shift+*

From the article you linked to:

The type can be one of the following values:

BINARY[(N)]

CHAR[(N)]

DATE

DATETIME

DECIMAL[(M[,D])]

SIGNED [INTEGER]

TIME

UNSIGNED [INTEGER]

Try SIGNED instead of INT

$('#saveBtn').off('click').on('click',function(){
   saveQuestion(id)
});

Assuming you have access to them (the properties you've declared are protected), you use them like this:

Person tom = new Person();
tom.Title = "A title";
string hisTitle = tom.Title;

These are properties. They're basically pairs of getter/setter methods (although you can have just a getter, or just a setter) with appropriate metadata. The example you've given is of automatically implemented properties where the compiler is adding a backing field. You can write the code yourself though. For example, the Title property you've declared is like this:

private string title; // Backing field
protected string Title
{
    get { return title; }  // Getter
    set { title = value; } // Setter
}

... except that the backing field is given an "unspeakable name" - one you can't refer to in your C# code. You're forced to go through the property itself.

You can make one part of a property more restricted than another. For example, this is quite common:

private string foo;
public string Foo
{
    get { return foo; }
    private set { foo = value; }
}

or as an automatically implemented property:

public string Foo { get; private set; }

Here the "getter" is public but the "setter" is private.

Some Android phones contain Busybox. Was hard to find.

To see if busybox was around:

ls -lR / | grep busybox

If you know it's around. You need some read/write space. Try you flash drive, /sdcard

cd /sdcard
ls -lR / >lsoutput.txt

upload to your computer. Upload the file. Get some text editor. Search for busybox. Will see what directory the file was found in.

busybox find /sdcard -iname 'python*'

to make busybox easier to access, you could:

cd /sdcard
ln -s /where/ever/busybox/is  busybox
/sdcard/busybox find /sdcard -iname 'python*'

Or any other place you want. R

The center class must have a width in order to make auto margin work:

.center { margin: 0 auto; width: 400px; }

Then I would apply the center class to the video itself, not a container:

<video class='center' …>…</video>

There are three parts to this:

1. original[::-1] reverses the original array. This notation is Python list slicing. This gives you a "sublist" of the original list described by [start:end:step], start is the first element, end is the last element to be used in the sublist. step says take every step'th element from first to last. Omitted start and end means the slice will be the entire list, and the negative step means that you'll get the elements in reverse. So, for example, if original was [x,y,z], the result would be [z,y,x]
2. The * when preceding a list/tuple in the argument list of a function call means "expand" the list/tuple so that each of its elements becomes a separate argument to the function, rather than the list/tuple itself. So that if, say, args = [1,2,3], then zip(args) is the same as zip([1,2,3]), but zip(*args) is the same as zip(1,2,3).
3. zip is a function that takes n arguments each of which is of length m and produces a list of length m, the elements of are of length n and contain the corresponding elements of each of the original lists. E.g., zip([1,2],[a,b],[x,y]) is [[1,a,x],[2,b,y]]. See also Python documentation.

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

I just created a discover.py file in my base test directory and added import statements for anything in my sub directories. Then discover is able to find all my tests in those directories by running it on discover.py

python -m unittest discover ./test -p '*.py'

# /test/discover.py
import unittest

from test.package1.mod1 import XYZTest
from test.package1.package2.mod2 import ABCTest

if __name__ == "__main__"
    unittest.main()

userType = (user.Type == 0) ? "Admin" : (user.type == 1) ? "User" : "Admin";

    select  Id , NameEn     from Company  ORDER by Id ASC

You might get this error when you import a class from another project, or change the path of the xaml file, or the namespace of either the xaml or behind .cs file.

One: It might have a namespace that is not the same as what you have in you new project

namespace TrainerB.MVC.Forms
{
     public partial class AboutDeveloper : ContentPage
     {
          public AboutDeveloper()
          {
               InitializeComponent();
          }
     }
}

As you can see the name space in the imported file begins with the old project name: "TrainerB", but your new project might have a different name, so just change it to the correct new project name, in both the .xaml file and the behind .cs file.

Two:

change the properties of the .xaml file to:

Build Action: Embedded Resource

Custom Tool: MSBuild:UpdateDesignTimeXaml

Typically, you'd use the NODE_ENV variable to take special actions when you develop, test and debug your code. For example to produce detailed logging and debug output which you don't want in production. Express itself behaves differently depending on whether NODE_ENV is set to production or not. You can see this if you put these lines in an Express app, and then make a HTTP GET request to /error:

app.get('/error', function(req, res) {
  if ('production' !== app.get('env')) {
    console.log("Forcing an error!");
  }
  throw new Error('TestError');
});

app.use(function (req, res, next) {
  res.status(501).send("Error!")
})

Note that the latter app.use() must be last, after all other method handlers!

If you set NODE_ENV to production before you start your server, and then send a GET /error request to it, you should not see the text Forcing an error! in the console, and the response should not contain a stack trace in the HTML body (which origins from Express). If, instead, you set NODE_ENV to something else before starting your server, the opposite should happen.

In Linux, set the environment variable NODE_ENV like this:

export NODE_ENV='value'

I can spot a few different problems with this. However, in the interest of time, try this chunk of code instead:

<?php require 'db.php'; ?>  <?php if (isset($_POST['search'])) {     $limit = $_POST['limit'];     $country = $_POST['country'];     $state = $_POST['state'];     $city = $_POST['city'];     $data = mysqli_query(         $link,         "SELECT * FROM proxies WHERE country = '{$country}' AND state = '{$state}' AND city = '{$city}' LIMIT {$limit}"     );     while ($assoc = mysqli_fetch_assoc($data)) {         $proxy = $assoc['proxy'];         ?>             <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"                 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">             <html xmlns="http://www.w3.org/1999/xhtml">                 <head>                     <title>Sock5Proxies</title>                     <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />                     <link href="./style.css" rel="stylesheet" type="text/css" />                     <link href="./buttons.css" rel="stylesheet" type="text/css" />                 </head>                 <body>                     <center>                         <h1>Sock5Proxies</h1>                     </center>                     <div id="wrapper">                         <div id="header">                             <ul id="nav">                                 <li class="active"><a href="index.html"><span></span>Home</a></li>                                 <li><a href="leads.html"><span></span>Leads</a></li>                                 <li><a href="payout.php"><span></span>Pay out</a></li>                                 <li><a href="contact.html"><span></span>Contact</a></li>                                 <li><a href="logout.php"><span></span>Logout</a></li>                             </ul>                         </div>                         <div id="content">                             <div id="center">                                 <table cellpadding="0" cellspacing="0" style="width:690px">                                     <thead>                                     <tr>                                         <th width="75" class="first">Proxy</th>                                         <th width="50" class="last">Status</th>                                     </tr>                                     </thead>                                     <tbody>                                     <tr class="rowB">                                         <td class="first"> <?php echo $proxy ?> </td>                                         <td class="last">Check</td>                                     </tr>                                     </tbody>                                 </table>                             </div>                         </div>                         <div id="footer"></div>                         <span id="about">Version 1.0</span>                     </div>                 </body>             </html>         <?php     } } ?> <html> <form action="" method="POST">     <input type="text" name="limit" placeholder="10" /><br>     <input type="text" name="country" placeholder="Country" /><br>     <input type="text" name="state" placeholder="State" /><br>     <input type="text" name="city" placeholder="City" /><br>     <input type="submit" name="search" value="Search" /><br> </form> </html> 

Here is how I do it in Python with Selenium 2.48.0:

from selenium.webdriver import Firefox
driver = Firefox()
driver.set_window_position(0, 0)
driver.set_window_size(1024, 768)

You can also look at the Date.getTime() API. That gives a long to which you can add your increment. Then create a new Date.

List<Date> dates = new ArrayList<Date>();
long interval = 1000 * 60 * 60; // 1 hour in millis
long endtime = ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
  dates.add(new Date(curTime));
  curTime += interval;
}

and maybe apache commons has something like this in DateUtils, or perhaps they have a CalendarUtils too :)

EDIT

including the start and enddate may not be possible if your interval is not perfect :)

For Windows users:

• Copy your Emulator name.
• Go to this directory: C:\Users\[yourusername]\AppData\Local\Android\Sdk\emulator
• Right click on emulator.exe and send as a shortcut to where you want.
• Right click on shortcut .exe file and add your Emulator name just copied to end of target textbox with @ symbol.
• Double click your shortcut and done!

From the Javadocs for setDisplayOrientation(int) (Requires API level 9):

 public static void setCameraDisplayOrientation(Activity activity,
         int cameraId, android.hardware.Camera camera) {
     android.hardware.Camera.CameraInfo info =
             new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     int rotation = activity.getWindowManager().getDefaultDisplay()
             .getRotation();
     int degrees = 0;
     switch (rotation) {
         case Surface.ROTATION_0: degrees = 0; break;
         case Surface.ROTATION_90: degrees = 90; break;
         case Surface.ROTATION_180: degrees = 180; break;
         case Surface.ROTATION_270: degrees = 270; break;
     }

     int result;
     if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
         result = (info.orientation + degrees) % 360;
         result = (360 - result) % 360;  // compensate the mirror
     } else {  // back-facing
         result = (info.orientation - degrees + 360) % 360;
     }
     camera.setDisplayOrientation(result);
 }

I think there are more solutions!

You can start the app, and here are 3 things you can do:

1. If the app shows for the first time the "import settings" dialog and then the "create/open a project" dialog, you can click on Settings > Manage License... > Remove License, and that removes for all Jetbrains products*.
2. If you open products like IntelliJ IDEA and have projects currently active (like the app open automatically the all IDE without prompt), then click on File > Close Project, and follow the first step.
3. Inside any app of IntelliJ, click on Help > Register... > Remove license.

*In case you have a license for a pack of products. If not, you have to remove the license per product individually. Check the 3rd step.

This can also be done with a regular expression

import re

input  = " Hello "
output = re.sub(r'^\s+|\s+$', '', input)
# output = 'Hello'

Yes.

When calling file_get_contents on a URL, one should use the stream_create_context function, which is fairly well documented on php.net.

This is more or less exactly covered on the following page at php.net in the user comments section: http://php.net/manual/en/function.stream-context-create.php

The get method of the HashMap is returning an Object, but the variable current is expected to take a ArrayList:

ArrayList current = new ArrayList();
// ...
current = dictMap.get(dictCode);

For the above code to work, the Object must be cast to an ArrayList:

ArrayList current = new ArrayList();
// ...
current = (ArrayList)dictMap.get(dictCode);

However, probably the better way would be to use generic collection objects in the first place:

HashMap<String, ArrayList<Object>> dictMap =
    new HashMap<String, ArrayList<Object>>();

// Populate the HashMap.

ArrayList<Object> current = new ArrayList<Object>();      
if(dictMap.containsKey(dictCode)) {
    current = dictMap.get(dictCode);   
}

The above code is assuming that the ArrayList has a list of Objects, and that should be changed as necessary.

For more information on generics, The Java Tutorials has a lesson on generics.

If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest

android:exported="true"

Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.

finish();

The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class in the code, so compile will fail.

I searched on the web and found something like this below, and it works well.

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);

You can also use the setClassName method:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();

You can also pass the values from one app to another app :

Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
    launchIntent.putExtra("AppID", "MY-CHILD-APP1");
    launchIntent.putExtra("UserID", "MY-APP");
    launchIntent.putExtra("Password", "MY-PASSWORD");
    startActivity(launchIntent);
    finish();
} else {
    Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}

Sorry, you can't view or download this file at this time is an error message that you may get when you try to download files on Google Drive.

Bandwidth limits

Limit                          Per hour            Per day
Download via web client        750 MB              1250 MB
Upload via web client          300 MB              500 MB

The explanation for the error message is simple: while users are free to share files publicly, or with a large number of users, quotas are in effect that limit availability.

If too many users view or download a file, it may be locked for a 24 hour period before the quota is reset. The period that a file is locked may be shorter according to Google.

If a file is particularly popular, it may take days or even longer before you manage to download it to your computer or place it on your Drive storage.

It could be a solution:

1. Locate the "uc" part of the address, and replace it with "open", so that the beginning of the URL reads * https:// drive.google.com/open?*

2. Load the address again once you have replaced uc with open in the address.

3. This loads a new screen with controls at the top.

4. Click on the "add to my drive" icon at the top right.

5. Click on "add to my drive" again to open your Google Drive storage in a new tab in the browser.

6. You should see the locked file on your drive now.

7. Select it with a right-click, and then the "make a copy" option from the menu.

   8.Select the copy of the file with a right-click, and there download to download the file to your local system.

Basically, what this does is create a copy of the file on your own Drive account. Since you are the owner of the copied file, you may download it to your local system this way.

Please note that this works only if you are signed in to a Google Account. Also note that you are the owner of the copied file and will be held responsible for policy violations or other issues linked to the file.

Another option is: Any public folder in Drive can host files and provide direct links to the files.

How to create the hosting URL: https:// googledrive.com/host/FolderID (your id file)

This will provide a folder that will give direct links to files inside the folder. Note: hosting view will not display files created in Google Docs.

My solution:

I had the same problem, so I made a JSON file in Google Drive but the URL file (.mp3) is in Dropbox. It is working fantastic even though I have 40,000 active user. I used this solution because I did not have time to search too much! I wrote you the Dropbox Limits anyway but I did not get problems with it

Traffic limits DROPBOX

Links and file requests are automatically banned if they generate unusually large amounts of traffic.

Dropbox Basic (free) accounts:

20 GB per day: The total amount of traffic that all of your links and file requests combined can generate without getting banned 100,000 downloads per day: The total number of downloads that all of your links combined can generate

Dropbox Plus and Business accounts: About 200 GB per day: The total amount of traffic that all of your links and file requests combined can generate without getting banned There's no daily limit to the number of downloads that your links can generate If your account hits our limit, we'll send a message to the email address registered to your account. Your links will be temporarily disabled, and anyone who tries to access them will see an error page instead of your files.

P.S. If you need more information about my files and how did it and How to make the URL File from Dropbox, I hope help to the people is reading this! (I posted it before but Someone deleted my last post)!

I need to somehow query Google and ask: Is this access token valid for [email protected]?

No. All you need is request standard login with Federated Login for Google Account Users from your API domain. And only after that you could compare "persistent user ID" with one you have from 'public interface'.

The value of realm is used on the Google Federated Login page to identify the requesting site to the user. It is also used to determine the value of the persistent user ID returned by Google.

So you need be from same domain as 'public interface'.

And do not forget that user needs to be sure that your API could be trusted ;) So Google will ask user if it allows you to check for his identity.

<strong> and <em> - unlike <b> and <i> - have clear purpose for web browsers for the blind.

A blind person doesn't browse the web visually, but by sound such as text readers. <strong> and <em>, in addition to encouraging something to be bold or italic, also convey loudness or stressing syllables respectively (OH MY! & Ooooooh Myyyyyyy!). Audio-only browsers are unpredictable when it comes to <b> and <i>... they may make them loud or stress them or they may not... you never can be sure unless you use <strong> and <em>.

$splitPos = strpos($url, "?/");
if ($splitPos !== false) {
    $url = substr($url, 0, $splitPos) . "?" . substr($url, $splitPos + 2);
}

Why not use a new Scanner for every reading? Like below. With this approach you will not confront your problem.

int i = new Scanner(System.in).nextInt();

StringBuilder will perform replace more efficiently, since its character array buffer can be specified to a required length.StringBuilder is designed for more than appending!

Of course the real question is whether this is an optimisation too far ? The JVM is very good at handling creation of multiple objects and the subsequent garbage collection, and like all optimisation questions, my first question is whether you've measured this and determined that it's a problem.

In Sublime Text, after you select multiple regions of text, a click is considered a way to exit the multi-select mode. Move the cursor with the keyboard keys (arrows, Ctrl+arrows, etc.) instead, and you'll be fine

You could try making the imageView size match the image. The following code is not tested.

CGSize kMaxImageViewSize = {.width = 100, .height = 100};
CGSize imageSize = image.size;
CGFloat aspectRatio = imageSize.width / imageSize.height;
CGRect frame = imageView.frame;
if (kMaxImageViewSize.width / aspectRatio <= kMaxImageViewSize.height) 
{
    frame.size.width = kMaxImageViewSize.width;
    frame.size.height = frame.size.width / aspectRatio;
} 
else 
{
    frame.size.height = kMaxImageViewSize.height;
    frame.size.width = frame.size.height * aspectRatio;
}
imageView.frame = frame;

For removing the default 'blue-border' from button on button focus:

In Html:

<button class="new-button">New Button...</button>

And in Css

button.new-button:focus {
    outline: none;
}

Hope it helps :)

Believe or not, keytool does not provide such basic functionality like importing private key to keystore. You can try this workaround with merging PKSC12 file with private key to a keystore:

keytool -importkeystore \
  -deststorepass storepassword \
  -destkeypass keypassword \
  -destkeystore my-keystore.jks \
  -srckeystore cert-and-key.p12 \
  -srcstoretype PKCS12 \
  -srcstorepass p12password \
  -alias 1

Or just use more user-friendly KeyMan from IBM for keystore handling instead of keytool.

Just write

<body>
   <center>
            *Your Code Here*
   </center></body>

Pushwatch is a free to use online GCM and APNS push notification tester developed by myself in Django/Python as I have found myself in a similar situation while working on multiple projects. It can send both GCM and APNS notifications and also support JSON messages for extra arguments. Following are the links to the testers.

Please let me know if you have any questions or face issues using it.

You can add leading zeroes to a variable (value up to 99) like this in batch: IF 1%Var% LSS 100 SET Var=0%Var%

So you'd need to parse your date and time components out into separate variables, treat them all like this, then concatenate them back together to create the file name.

However, your underlying method for parsing date and time is dependent on system locale settings. If you're happy for your code not to be portable to other machines, that's probably fine, but if you expect it to work in different international contexts then you'll need a different approach, for example by reading out the registry settings:

HKEY_CURRENT_USER\Control Panel\International\iDate
HKEY_CURRENT_USER\Control Panel\International\iTime
HKEY_CURRENT_USER\Control Panel\International\iTLZero

(That last one controls whether there is a leading zero on times, but not dates as far as I know).

You can't do this without JavaScript. Stackoverflow is using the jQuery JavaScript library which attachs functions to HTML elements on page load.

Here's how you could do it with vanilla JavaScript:

<textarea onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>

Keycode 13 is the enter key.

Here's how you could do it with jQuery like as Stackoverflow does:

<textarea class="commentarea"></textarea>

with

$(document).ready(function() {
    $('.commentarea').keydown(function(event) {
        if (event.which == 13) {
            this.form.submit();
            event.preventDefault();
         }
    });
});

First off I should point out that css animations would probably work best if you are doing this a lot but I ended getting the desired effect by wrapping .scrollLeft inside .animate

$('.swipeRight').click(function()
{

    $('.swipeBox').animate( { scrollLeft: '+=460' }, 1000);
});

$('.swipeLeft').click(function()
{
    $('.swipeBox').animate( { scrollLeft: '-=460' }, 1000);
});

The second parameter is speed, and you can also add a third parameter if you are using smooth scrolling of some sort.

1. Go to Xcode preferences by clicking on "Xcode" in the left hand side upper corner.

2. Select "Text Editing".

3. Select "Show: Line numbers" and click on check box for enable it.

4. Close it.

Then you will see the line number in Xcode.

• Factory method

java.util.Collection#Iterator is a good example of a Factory Method. Depending on the concrete subclass of Collection you use, it will create an Iterator implementation. Because both the Factory superclass (Collection) and the Iterator created are interfaces, it is sometimes confused with AbstractFactory. Most of the examples for AbstractFactory in the the accepted answer (BalusC) are examples of Factory, a simplified version of Factory Method, which is not part of the original GoF patterns. In Facory the Factory class hierarchy is collapsed and the factory uses other means to choose the product to be returned.

• Abstract Factory

An abstract factory has multiple factory methods, each creating a different product. The products produced by one factory are intended to be used together (your printer and cartridges better be from the same (abstract) factory). As mentioned in answers above the families of AWT GUI components, differing from platform to platform, are an example of this (although its implementation differs from the structure described in Gof).

Unfortunately, combining multiple entity contexts into a single named connection isn't possible. If you want to use named connection strings from a .config file to define your Entity Framework connections, they will each have to have a different name. By convention, that name is typically the name of the context:

<add name="ModEntity" connectionString="metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
<add name="Entity" connectionString="metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SOMESERVER;Initial Catalog=SOMECATALOG;Persist Security Info=True;User ID=Entity;Password=Entity;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

However, if you end up with namespace conflicts, you can use any name you want and simply pass the correct name to the context when it is generated:

var context = new Entity("EntityV2");

Obviously, this strategy works best if you are using either a factory or dependency injection to produce your contexts.

Another option would be to produce each context's entire connection string programmatically, and then pass the whole string in to the constructor (not just the name).

// Get "Data Source=SomeServer..."
var innerConnectionString = GetInnerConnectionStringFromMachinConfig();
// Build the Entity Framework connection string.
var connectionString = CreateEntityConnectionString("Entity", innerConnectionString);
var context = new EntityContext(connectionString);

How about something like this:

Type contextType = typeof(test_Entities);
string innerConnectionString = ConfigurationManager.ConnectionStrings["Inner"].ConnectionString;
string entConnection = 
    string.Format(
        "metadata=res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl;provider=System.Data.SqlClient;provider connection string=\"{1}\"",
        contextType.Name,
        innerConnectionString);
object objContext = Activator.CreateInstance(contextType, entConnection);
return objContext as test_Entities; 

... with the following in your machine.config:

<add name="Inner" connectionString="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />

This way, you can use a single connection string for every context in every project on the machine.

If you are building your application using Spring Framework I would suggest using javax.validation.constraints.NotNull comming from Beans Validation packaged in following dependency:

    <dependency>
        <groupId>javax.validation</groupId>
        <artifactId>validation-api</artifactId>
        <version>1.1.0.Final</version>
    </dependency>

The main advantage of this annotation is that Spring provides support for both method parameters and class fields annotated with javax.validation.constraints.NotNull. All you need to do to enable support is:

1. supply the api jar for beans validation and jar with implementation of validator of jsr-303/jsr-349 annotations (which comes with Hibernate Validator 5.x dependency):

   <dependency>
       <groupId>javax.validation</groupId>
       <artifactId>validation-api</artifactId>
       <version>1.1.0.Final</version>
   </dependency>
   <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-validator</artifactId>
       <version>5.4.1.Final</version>
   </dependency>
   

2. provide MethodValidationPostProcessor to spring's context

     @Configuration
     @ValidationConfig
     public class ValidationConfig implements MyService {
   
           @Bean
           public MethodValidationPostProcessor providePostProcessor() {
                 return new MethodValidationPostProcessor()
           }
     }
   

3. finally you annotate your classes with Spring's org.springframework.validation.annotation.Validated and validation will be automatically handled by Spring.

Example:

@Service
@Validated
public class MyServiceImpl implements MyService {

  @Override
  public Something doSomething(@NotNull String myParameter) {
        // No need to do something like assert myParameter != null  
  }
}

When you try calling method doSomething and pass null as the parameter value, spring (by means of HibernateValidator) will throw ConstraintViolationException. No need for manuall work here.

You can also validate return values.

Another important benefit of javax.validation.constraints.NotNull comming for Beans Validation Framework is that at the moment it is still developed and new features are planned for new version 2.0.

What about @Nullable? There is nothing like that in Beans Validation 1.1. Well, I could arguee that if you decide to use @NotNull than everything which is NOT annotated with @NonNull is effectively "nullable", so the @Nullable annotation is useless.

When you want to show an URL of remote branches, try:

You could put the body of your script into a function and then you could return from that function.

def main():
  done = True
  if done:
    return
    # quit/stop/exit
  else:
    # do other stuff

if __name__ == "__main__":
  #Run as main program
  main()

For those who use JSF2.2+ and cannot pass autofocus as an attribute without value to it, use this:

 p:autofocus="true"

And add it to the namespace p (Also often used pt. Whatever you like).

<html ... xmlns:p="http://java.sun.com/jsf/passthrough">

Use JQuery keydown event.

$(document).keypress(function(){
    if(event.which == 70){  //f
        console.log("You have payed respect");
    }
});

In JS; keyboard keys are identified by Javascript keycodes

A pop-up is a child of the parent window, but it is not a child of the parent DOCUMENT. It is its own independent browser window and is not contained by the parent.

Use an absolutely-positioned DIV and a translucent overlay instead.

EDIT - example

You need jQuery for this:

<style>
html, body {
    height:100%
}


#overlay { 
    position:absolute;
    z-index:10;
    width:100%;
    height:100%;
    top:0;
    left:0;
    background-color:#f00;
    filter:alpha(opacity=10);
    -moz-opacity:0.1;
    opacity:0.1;
    cursor:pointer;

} 

.dialog {
    position:absolute;
    border:2px solid #3366CC;
    width:250px;
    height:120px;
    background-color:#ffffff;
    z-index:12;
}

</style>
<script type="text/javascript">
$(document).ready(function() { init() })

function init() {
    $('#overlay').click(function() { closeDialog(); })
}

function openDialog(element) {
    //this is the general dialog handler.
    //pass the element name and this will copy
    //the contents of the element to the dialog box

    $('#overlay').css('height', $(document.body).height() + 'px')
    $('#overlay').show()
    $('#dialog').html($(element).html())
    centerMe('#dialog')
    $('#dialog').show();
}

function closeDialog() {
    $('#overlay').hide();
    $('#dialog').hide().html('');
}

function centerMe(element) {
    //pass element name to be centered on screen
    var pWidth = $(window).width();
    var pTop = $(window).scrollTop()
    var eWidth = $(element).width()
    var height = $(element).height()
    $(element).css('top', '130px')
    //$(element).css('top',pTop+100+'px')
    $(element).css('left', parseInt((pWidth / 2) - (eWidth / 2)) + 'px')
}


</script>


<a href="javascript:;//close me" onclick="openDialog($('#content'))">show dialog A</a>

<a href="javascript:;//close me" onclick="openDialog($('#contentB'))">show dialog B</a>

<div id="dialog" class="dialog" style="display:none"></div>

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

Ref:- Microsoft Docs for port Opening

It seems you need to do combobox->itemData(combobox->currentIndex()) if you want to get the current data of the QComboBox.

If you are using your own class derived from QComboBox, you can add a currentData() function.

try:

  foreach (var item in chlCompanies.CheckedItems){
     item.Value //ID
     item.Text //CompanyName
  }

based on GuyPaddock's answer from above, this seems to work for me

function getLinesCount(element) {
  var prevLH = element.style.lineHeight;
  var factor = 1000;
  element.style.lineHeight = factor + 'px';

  var height = element.getBoundingClientRect().height;
  element.style.lineHeight = prevLH;

  return Math.floor(height / factor);
}

the trick here is to increase the line-height so much that it will "swallow" any browser / OS differences in the way that they render fonts

Checked it with various stylings and different font sizes / families only thing that it doesn't take into account (since in my case it didnt matter), is the padding - which can easily be added to the solution.

Not answering the question directly, but it might help someone else.

I have a column called Volume, having both - (invalid/NaN) and numbers formatted with ,

df['Volume'] = df['Volume'].astype('str')
df['Volume'] = df['Volume'].str.replace(',', '')
df['Volume'] = pd.to_numeric(df['Volume'], errors='coerce')

Casting to string is required for it to apply to str.replace

pandas.Series.str.replace
pandas.to_numeric

var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:

var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);

You might have old invalid username/password cached in your browser. Try clearing them and check again.

If you are using IE and somesite.com is in your Intranet security zone, IE may be sending your windows credentials automatically.

First, I think you're calling it the wrong thing. "JSON" stands for "JavaScript Object Notation" - it's just a specification for representing some data in a string that explicitly mimics JavaScript object (and array, string, number and boolean) literals. You're trying to build up a JavaScript object dynamically - so the word you're looking for is "object".

With that pedantry out of the way, I think that you're asking how to set object and array properties.

// make an empty object
var myObject = {};

// set the "list1" property to an array of strings
myObject.list1 = ['1', '2'];

// you can also access properties by string
myObject['list2'] = [];
// accessing arrays is the same, but the keys are numbers
myObject.list2[0] = 'a';
myObject['list2'][1] = 'b';

myObject.list3 = [];
// instead of placing properties at specific indices, you
// can push them on to the end
myObject.list3.push({});
// or unshift them on to the beginning
myObject.list3.unshift({});
myObject.list3[0]['key1'] = 'value1';
myObject.list3[1]['key2'] = 'value2';

myObject.not_a_list = '11';

That code will build up the object that you specified in your question (except that I call it myObject instead of myJSON). For more information on accessing properties, I recommend the Mozilla JavaScript Guide and the book JavaScript: The Good Parts.

I was also facing this issue and I just add www in url like -

https://www.your-domain.com/

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:

My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.

private void startCreation(){
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_PICK);
    Uri startDir = Uri.fromFile(new File("/sdcard"));

    intent.setDataAndType(startDir,
            "vnd.android.cursor.dir/lysesoft.andexplorer.file");
    intent.putExtra("browser_filter_extension_whitelist", "*.csv");
    intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
    intent.putExtra("browser_title_background_color",
            getText(R.string.browser_title_background_color));
    intent.putExtra("browser_title_foreground_color",
            getText(R.string.browser_title_foreground_color));
    intent.putExtra("browser_list_background_color",
            getText(R.string.browser_list_background_color));
    intent.putExtra("browser_list_fontscale", "120%");
    intent.putExtra("browser_list_layout", "2");

    try{
         ApplicationInfo info = getPackageManager()
                                 .getApplicationInfo("lysesoft.andexplorer", 0 );

            startActivityForResult(intent, PICK_REQUEST_CODE);
    } catch( PackageManager.NameNotFoundException e ){
        showInstallResultMessage(R.string.error_install_andexplorer);
    } catch (Exception e) {
        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

I was almost using the same technology as you did, however I was using my app to connect an Exchange Server via Office 365 platform on WinForms. I too had the same issue as you did, but was able to accomplish by using code which has slight modification of what others have given above.

SmtpClient client = new SmtpClient(exchangeServer, 587);
client.Credentials = new System.Net.NetworkCredential(username, password);
client.EnableSsl = true;
client.Send(msg);

I had to use the Port 587, which is of course the default port over TSL and the did the authentication.

A basic for statement includes

• 0..n initialization statements (ForInit)
• 0..1 expression statements that evaluate to boolean or Boolean (ForStatement) and
• 0..n update statements (ForUpdate)

If you need multiple conditions to build your ForStatement, then use the standard logic operators (&&, ||, |, ...) but - I suggest to use a private method if it gets to complicated:

for (int i = 0, j = 0; isMatrixElement(i,j,myArray); i++, j++) { 
   // ...
}

and

private boolean isMatrixElement(i,j,myArray) {
  return (i < myArray.length) && (j < myArray[i].length);  //  stupid dummy code!
}

git stash is your friend.

If you have not made the commit yet, just run git stash. This will save away all of your changes.

Switch to the branch you want the changes on and run git stash pop.

There are lots of uses for git stash. This is certainly one of the more useful reasons.

An example:

# work on some code
git stash
git checkout correct-branch
git stash pop
