i needed to calculate the content length aswell

const formHeaders = form.getHeaders();
formHeaders["Content-Length"] = form.getLengthSync()

const config = {headers: formHeaders}

return axios.post(url, form, config)
.then(res => {
    console.log(`form uploaded`)
})

If you're array structure will always be multi-dimensional in that exact fashion, then we can iterate through the elements like such:

$fh = fopen('somefile.csv', 'w') or die('Cannot open the file');

for( $i=0; $i<count($arr); $i++ ){
    $str = implode( ',', $arr[$i] );
    fwrite( $fh, $str );
    fwrite( $fh, "\n" );
}
fclose($fh);

That's one way to do it ... you could do it manually but this way is quicker and easier to understand and read.

Then you would manage your headers something what complex857 is doing to spit out the file. You could then delete the file using unlink() if you no longer needed it, or you could leave it on the server if you wished.

I prefer to use this:

final protected static char[] hexArray = "0123456789ABCDEF".toCharArray();
public static String bytesToHex(byte[] bytes, int offset, int count) {
    char[] hexChars = new char[count * 2];
    for ( int j = 0; j < count; j++ ) {
        int v = bytes[j+offset] & 0xFF;
        hexChars[j * 2] = hexArray[v >>> 4];
        hexChars[j * 2 + 1] = hexArray[v & 0x0F];
    }
    return new String(hexChars);
}

It is slightly more flexible adaptation of the accepted answer. Personally, I keep both the accepted answer and this overload along with it, usable in more contexts.

this solution worked for me:

On your remote machine (example: 295.13.12.53) has access to your target remote machine (which runs mysql server)

ssh -f -L 295.13.12.53:3306:10.18.81.36:3306 [email protected]

Explained:

ssh -f -L your_ssh_mashine_ipaddress:your_ssh_mashine_local_port:target_ipaddress:target_port user@your_ip_address -N

your_ssh_mashine_ipaddress - it is not local ip address, it is ip address that you ssh to, in this example 295.13.12.53

your_ssh_mashine_local_port -this is custom port not 22, in this example it is 3306.

target_ipaddress - ip of the machine that you trying to dump DB.

target_port - 3306 this is real port for MySQL server.

user@your_ip_address - this is ssh credentials for the ssh mashine that you connect

Once all this done then go back to your machine and do this:

mysqldump -h 295.13.12.53 -P 3306 -u username -p db_name > dumped_db.sql

Will ask for password, put your password and you are connected. Hope this helps.

Create a helper using the code I created belows and name it controller_helper.php.

Autoload your helper in the autoload.php file under config.

From your method call controller('name') to load the controller.

Note that name is the filename of the controller.

This method will append '_controller' to your controller 'name'. To call a method in the controller just run $this->name_controller->method(); after you load the controller as described above.

<?php

if(!function_exists('controller'))
{
    function controller($name)
    {
        $filename = realpath(__dir__ . '/../controllers/'.$name.'.php');

        if(file_exists($filename))
        {
            require_once $filename;

            $class = ucfirst($name);

            if(class_exists($class))
            {
                $ci =& get_instance();

                if(!isset($ci->{$name.'_controller'}))
                {
                    $ci->{$name.'_controller'} = new $class();
                }
            }
        }
    }
}
?>

Typically for dynamic lists of items, you use a std::vector.

Generally I use memset or a loop for raw memory dynamic allocation, depending on how variable I anticipate that area of code to be in the future.

I recommend PyInstaller, a simple python script can be converted to an exe with the following commands:

utils/Makespec.py [--onefile] oldlogs.py

which creates a yourprogram.spec file which is a configuration for building the final exe. Next command builds the exe from the configuration file:

utils/Build.py oldlogs.spec

pandas read_csv method is great for parsing dates. Complete documentation at http://pandas.pydata.org/pandas-docs/stable/generated/pandas.io.parsers.read_csv.html

you can even have the different date parts in different columns and pass the parameter:

parse_dates : boolean, list of ints or names, list of lists, or dict
If True -> try parsing the index. If [1, 2, 3] -> try parsing columns 1, 2, 3 each as a
separate date column. If [[1, 3]] -> combine columns 1 and 3 and parse as a single date
column. {‘foo’ : [1, 3]} -> parse columns 1, 3 as date and call result ‘foo’

The default sensing of dates works great, but it seems to be biased towards north american Date formats. If you live elsewhere you might occasionally be caught by the results. As far as I can remember 1/6/2000 means 6 January in the USA as opposed to 1 Jun where I live. It is smart enough to swing them around if dates like 23/6/2000 are used. Probably safer to stay with YYYYMMDD variations of date though. Apologies to pandas developers,here but i have not tested it with local dates recently.

you can use the date_parser parameter to pass a function to convert your format.

date_parser : function
Function to use for converting a sequence of string columns to an array of datetime
instances. The default uses dateutil.parser.parser to do the conversion.

macOS

I'm running Virtual Box on macOS (previously OS X), using Virtual Box to test IE on Windows, etc.

Go to IE in Virtual Box and access localhost via http://10.0.2.2 for localhost, or http://10.0.2.2:3000 for localhost:3000.

I kept Network settings as NAT, no need for bridge as suggested above in my case. There is no need to edit any config files.

I am just providing another case where you can get this error message. The solution will be the same as Adam has mentioned above. This is from a real code and I renamed the class name.

class FooReader {
  public:
     /** Constructor */
     FooReader() : d(new FooReaderPrivate(this)) { }  // will not compile here
     .......
  private:
     FooReaderPrivate* d;
};

====== In a separate file =====
class FooReaderPrivate {
  public:
     FooReaderPrivate(FooReader*) : parent(p) { }
  private:
     FooReader* parent;
};

The above will no pass the compiler and get error: invalid use of incomplete type FooReaderPrivate. You basically have to put the inline portion into the *.cpp implementation file. This is OK. What I am trying to say here is that you may have a design issue. Cross reference of two classes may be necessary some cases, but I would say it is better to avoid them at the start of the design. I would be wrong, but please comment then I will update my posting.

With the Material Components Library you can use the MaterialShapeDrawable to draw custom shapes.

With a EditText you can do:

    <EditText
        android:id="@+id/edittext"
        ../>

Then create a MaterialShapeDrawable:

float radius = getResources().getDimension(R.dimen.default_corner_radius);

EditText editText = findViewById(R.id.edittext);
//Apply the rounded corners 
ShapeAppearanceModel shapeAppearanceModel = new ShapeAppearanceModel()
                .toBuilder()
                .setAllCorners(CornerFamily.ROUNDED,radius)
                .build();

MaterialShapeDrawable shapeDrawable = 
            new MaterialShapeDrawable(shapeAppearanceModel);
//Apply a background color
shapeDrawable.setFillColor(ContextCompat.getColorStateList(this,R.color.white));
//Apply a stroke
shapeDrawable.setStroke(2.0f, ContextCompat.getColor(this,R.color.colorAccent));

ViewCompat.setBackground(editText,shapeDrawable);

It requires the version 1.1.0 of the library.

You could do this:

find ./ -type f -ls |grep '10 Sep'

Example:

[root@pbx etc]# find /var/ -type f -ls | grep "Dec 24"
791235    4 -rw-r--r--   1 root     root           29 Dec 24 03:24 /var/lib/prelink/full
798227  288 -rw-r--r--   1 root     root       292323 Dec 24 23:53 /var/log/sa/sar24
797244  320 -rw-r--r--   1 root     root       321300 Dec 24 23:50 /var/log/sa/sa24

For other circumstances in which you want the number string to be consistent, I made a function.

Someone may find this useful:

idnamer<-function(x,y){#Alphabetical designation and number of integers required
    id<-c(1:y)
    for (i in 1:length(id)){
         if(nchar(id[i])<2){
            id[i]<-paste("0",id[i],sep="")
         }
    }
    id<-paste(x,id,sep="")
    return(id)
}
idnamer("EF",28)

Sorry about the formatting.

Since version 2018-09-15 (3.25.0) sqlite supports renaming columns

https://sqlite.org/changes.html

I was trying to go through a list of objects, display them as rows in a table, with each row being a link. This worked for me. Hope it helps.

// CUSTOMER_LIST is a model attribute
<table>
    <th:block th:each="customer : ${CUSTOMER_LIST}">
        <tr>
            <td><a th:href="@{'/main?id=' + ${customer.id}}" th:text="${customer.fullName}" /></td>
        </tr>
    </th:block>
</table>

I think you may need to stringify the data using JSON.stringify.

 var data = JSON.stringify({ 
                 'StrContactDetails': Details,
                 'IsPrimary':true
               });

$.ajax({
        type: "POST",
        url: @url.Action("Dhp","SaveEmergencyContact"),
        data: data,
        success: function(){},
        contentType: 'application/json'
    });

So the controller method would look like,

public ActionResult SaveEmergencyContact(string  StrContactDetails, bool IsPrimary)

• Step 1. Install homebrew from here: http://brew.sh
• Step 1.1. Run export PATH=/usr/local/bin:$PATH
• Step 2. Run brew update
• Step 3. Run brew install vim && brew install macvim
• Step 4. Run brew link macvim

You now have the latest versions of vim and macvim managed by brew. Run brew update && brew upgrade every once in a while to upgrade them.

This includes the installation of the CLI mvim and the mac application (which both point to the same thing).

I use this setup and it works like a charm. Brew even takes care of installing vim with the preferable options.

What about element.tagName?

See also tagName docs on MDN.

You can use COALESCE in conjunction with NULLIF for a short, efficient solution:

COALESCE( NULLIF(yourField,'') , '0' )

The NULLIF function will return null if yourField is equal to the second value ('' in the example), making the COALESCE function fully working on all cases:

                 QUERY                     |                RESULT 
---------------------------------------------------------------------------------
SELECT COALESCE(NULLIF(null  ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF(''    ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF('foo' ,''),'0')     |                 'foo'

I believe this error caused because of downloading SRC instead of BINARY from Maven site. Please make sure to download Binary zip.

Because the below path, you will get only when you download SRC:

M2_HOME C:\apache-maven-3.0.4\apache-maven\src

>>> list1 = [[], [], [], [], [], 'text', 'text2', [], 'moreText']
>>> list2 = [e for e in list1 if e]
>>> list2
['text', 'text2', 'moreText']

The line: result = result * i should be indented (it is the body of the for-loop).

Or - you have mixed space and tab characters

    // Standard library packages

    r.GET("/ip", getIP)

    // Add a handler on /test
    r.GET("/test", func(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
        // Simply write some test data for now
        fmt.Fprint(w, "Welcome!\n")
    })  


    l, err := net.Listen("tcp", "localhost:" + myport)
    if err != nil {

    // The browser can connect now because the listening socket is open.


    //err = open.Start("http://localhost:"+ myport + "/test")
    err = open.Start("http://localhost:"+ myport + "/ip")
    if err != nil {
         log.Println(err)
    }

    // Start the blocking server loop.
    log.Fatal(http.Serve(l, r)) 
}

Please Try this code margin-left:60px instead of left:60px

please take a look: http://jsfiddle.net/hbirjand/2LtBh/2/

as @Shomz said,transition must be changed to transition:margin 1s linear; instead of transition:all 1s linear;

If you want to use SimpleDateFormat, you could write:

private final SimpleDateFormat sdf =
    new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
    { sdf.setTimeZone(TimeZone.getTimeZone("GMT")); }

private long parseTimeToMillis(final String time) throws ParseException
    { return sdf.parse("1970-01-01 " + time).getTime(); }

But a custom method would be much more efficient. SimpleDateFormat, because of all its calendar support, time-zone support, daylight-savings-time support, and so on, is pretty slow. The slowness is worth it if you actually need some of those features, but since you don't, it might not be. (It depends how often you're calling this method, and whether efficiency is a concern for your application.)

Also, SimpleDateFormat is non-thread-safe, which is sometimes a pain. (Without knowing anything about your application, I can't guess whether that matters.)

Personally, I'd probably write a custom method.

Use QString's number method (docs are here):

double valueAsDouble = 1.2;
QString valueAsString = QString::number(valueAsDouble);

You can use the Ildasm.exe (IL Disassembler) to examine the assembly's metadata, which contains the fully qualified name.

Following MSDN: https://msdn.microsoft.com/en-us/library/2exyydhb(v=vs.110).aspx

You can use:

To Insert After,

jQuery("#source").insertAfter("#destination");

To Insert inside another element,

jQuery("#source").appendTo("#destination");

first_line = next(open(filename))

I second Harmen's div suggestion. Alternatively, you can wrap the table in a form, and use javascript to capture the row focus and adjust the form action via javascript before submit.

The functions current_date and current_timestamp are now available in Hive 1.2.0 and higher, which makes the code a lot cleaner.

Try it out

el {
  transform-style: preserve-3d;
}
el:after {
  transform: translateZ(-1px);
}

I am using following command to get latest images

sudo docker-compose down -rmi all

sudo docker-compose up -d

Use org.apache.commons.lang.StringUtils' split method which can split strings based on the character or string you want to split.

Method signature:

public static String[] split(String str, char separatorChar);

In your case, you want to split a string when there is a "-".

You can simply do as follows:

String str = "004-034556";

String split[] = StringUtils.split(str,"-");

Output:

004
034556

Assume that if - does not exists in your string, it returns the given string, and you will not get any exception.

This refers to the object you’re “in” right now. In other words,this refers to the receiving object. You use this to clarify which variable you’re referring to.Java_whitepaper page :37

class Point extends Object
{
    public double x;
    public double y;

    Point()
    {
        x = 0.0;
        y = 0.0;
    }

    Point(double x, double y)
    {
        this.x = x;
        this.y = y;
    }
}

In the above example code this.x/this.y refers to current class that is Point class x and y variables where (double x,double y) are double values passed from different class to assign values to current class .

XSD (XML schema definition) defines the element in an XML document. It can be used to verify if the elements in the xml document adheres to the description in which the content is to be placed. While wsdl is specific type of XML document which describes the web service. WSDL itself adheres to a XSD.

Without the main sentinel, the code would be executed even if the script were imported as a module.

Works in both with postgresql and Oracle

SELECT ename, sal, round(((sal * .15 + comm) /12),2) 
FROM emp where job = 'SALESMAN' 

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

Your method will return a local stack variable that will fail badly. To return an array, create one outside the function, pass it by address into the function, then modify it, or create an array on the heap and return that variable. Both will work, but the first doesn't require any dynamic memory allocation to get it working correctly.

void returnArray(int size, char *retArray)
{
  // work directly with retArray or memcpy into it from elsewhere like
  // memcpy(retArray, localArray, size); 
}

#define ARRAY_SIZE 20

int main(void)
{
  char foo[ARRAY_SIZE];
  returnArray(ARRAY_SIZE, foo);
}

Here are some boilerplate code for PHP + curl http://www.webbotsspidersscreenscrapers.com/DSP_download.php

include in these library will simplify development

$product_array=array();
$product_count=0;

# Download the target (store) web page
$target = "http://www.tellmewhenitchanges.com/buyair";
$web_page = http_get($target, "");
    ...
?>

I am guessing you are trying to mix Asp code and JS code and at some point it's breaking or not excusing the binding calls correctly.

Perhaps you can try using a delegate instead. It will cut out the complexity of when to bind the click event.

An example would be:

$('body').delegate('.menu li','click',function(){
   var $li = $(this);

   var shouldAddClass = $li.find('a[href^="www.xyz.com/link1"]').length != 0;

   if(shouldAddClass){
       $li.addClass('active');
   }
});

See if that helps, it uses the Attribute Starts With Selector from jQuery.

If you want to use bootstrap dropdowns, I will recommend this for angular2:

Bandwidth is tiered by instance size, here's a comprehensive answer:

For t2/m3/c3/c4/r3/i2/d2 instances:

• t2.nano = ??? (Based on the scaling factors, I'd expect 20-30 MBit/s)
• t2.micro = ~70 MBit/s (qiita says 63 MBit/s) - t1.micro gets about ~100 Mbit/s
• t2.small = ~125 MBit/s (t2, qiita says 127 MBit/s, cloudharmony says 125 Mbit/s with spikes to 200+ Mbit/s)
• *.medium = t2.medium gets 250-300 MBit/s, m3.medium ~400 MBit/s
• *.large = ~450-600 MBit/s (the most variation, see below)
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput

m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.

I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).

Caveats & Notes:

The large instance size has the most variation reported:

• m1.large is ~800 Mbit/s (!!!)
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s (different results from different sources)
• c4.large = ~520 MBit/s (I've confirmed this independently, by the way)
• m3.large is better at ~700 MBit/s
• m4.large is ~445 Mbit/s
• r3.large is ~390 Mbit/s

Burstable (T2) instances appear to exhibit burstable networking performance too:

• The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:

• t2.small (PDF)

• t2.medium (PDF)
• t2.large (PDF)

Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.

I would recommend the following.

<button [disabled]="isInvalid()">Submit</button>

I've tried different numbers, and it always acts as if the 0s aren't there and sorts the numbers correctly otherwise. Anyone know why?

You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Javascript:

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort

array.sort([compareFunction])

Parameters

compareFunction

Specifies a function that defines the sort order. If omitted, the array is sorted lexicographically (in dictionary order) according to the string conversion of each element.

In the ECMAscript specification (the normative reference for the generic Javascript), ECMA-262, 3rd ed., section 15.4.4.11, the default sort order is lexicographical, although they don't come out and say it, instead giving the steps for a conceptual sort function that calls the given compare function if necessary, otherwise comparing the arguments when converted to strings:

13. If the argument comparefn is undefined, go to step 16.
14. Call comparefn with arguments x and y.
15. Return Result(14).
16. Call ToString(x).
17. Call ToString(y).
18. If Result(16) < Result(17), return -1.
19. If Result(16) > Result(17), return 1.
20. Return +0.

Best practice of getting length is use length filter returns the number of items of a sequence or mapping, or the length of a string. For example: {{ notcount | length }}

But you can calculate count of elements in for loop. For example:

{% set count = 0 %}
{% for nc in notcount %}
    {% set count = count + 1 %}
{% endfor %}

{{ count }}

This solution helps if you want to calculate count of elements by condition, for example you have a property name inside object and you want to calculate count of objects with not empty names:

{% set countNotEmpty = 0 %}
{% for nc in notcount if nc.name %}
    {% set countNotEmpty = countNotEmpty + 1 %}
{% endfor %}

{{ countNotEmpty }}

Useful links:

• length
• set
• for

Stripping things down to basics this is what you would want to test with:

import socket
server = socket.socket() 
server.bind(("10.0.0.1", 6677)) 
server.listen(4) 
client_socket, client_address = server.accept()
print(client_address, "has connected")
while 1==1:
    recvieved_data = client_socket.recv(1024)
    print(recvieved_data)

This works assuming a few things:

1. Your local IP address (on the server) is 10.0.0.1 (This video shows you how)
2. No other software is listening on port 6677

Also note the basic concept of IP addresses:

Try the following, open the start menu, in the "search" field type cmd and press enter. Once the black console opens up type ping www.google.com and this should give you and IP address for google. This address is googles local IP and they bind to that and obviously you can not bind to an IP address owned by google.

With that in mind, you own your own set of IP addresses. First you have the local IP of the server, but then you have the local IP of your house. In the below picture 192.168.1.50 is the local IP of the server which you can bind to. You still own 83.55.102.40 but the problem is that it's owned by the Router and not your server. So even if you visit http://whatsmyip.com and that tells you that your IP is 83.55.102.40 that is not the case because it can only see where you're coming from.. and you're accessing your internet from a router.

In order for your friends to access your server (which is bound to 192.168.1.50) you need to forward port 6677 to 192.168.1.50 and this is done in your router. Assuming you are behind one.

If you're in school there's other dilemmas and routers in the way most likely.

according to pkarat's, law you can achieve conditional XPath in version 1.0.

For your case, follow the concept:

concat(substring-before(your-xpath[contains(.,':')],':'),your-xpath[not(contains(.,':'))])

This will definitely work. See how it works. Give two inputs

praba:
karan

For 1st input: it contains : so condition true, string before : will be the output, say praba is your output. 2nd condition will be false so no problems.

For 2nd input: it does not contain : so condition fails, coming to 2nd condition the string doesn't contain : so condition true... therefore output karan will be thrown.

Finally your output would be praba,karan.

If you want difference in seconds

SELECT strftime('%s', '2019-12-02 12:32:53') - strftime('%s', '2019-12-02 11:32:53')

For relative imports you have to:

• a) use relative name

• b) provide anchor explicitly

  importlib.import_module('.c', 'a.b')
  

Of course, you could also just do absolute import instead:

importlib.import_module('a.b.c')

jQuery Sparkle includes a custom event for this. The source can be seen here: http://github.com/balupton/jquery-sparkle/blob/master/scripts/resources/jquery.events.js

Here is a demo http://www.balupton.com/sandbox/jquery-sparkle/demo/#event-enter

The best way is to use display:

inline-block; 

and

overflow: hidden;

The solution that really works turned out to be setting simple error handler with E_WARNING parameter, like so:

set_error_handler("warning_handler", E_WARNING);
dns_get_record(...)
restore_error_handler();

function warning_handler($errno, $errstr) { 
// do something
}

Sure .. you can simply use the key attribute to force re-render (recreation) at any time.

<mycomponent :key="somevalueunderyourcontrol"></mycomponent>

It was also discussed here: https://github.com/vuejs/Discussion/issues/356#issuecomment-336060875

Make sure, that all of your class methods (updateVelocity, updatePosition, ...) take at least one positional argument, which is canonically named self and refers to the current instance of the class.

When you call particle.updateVelocity(), the called method implicitly gets an argument: the instance, here particle as first parameter.

System environment variables are globally accessed by all users.
User environment variables are specific only to the currently logged-in user.

You might try running the script through JSLint.

The point seems to be that sometimes, you need a property that has automatic storage and some behavior, for instance to notify other objects that the property just changed. When all you have is get/set, you need another field to hold the value. With willSet and didSet, you can take action when the value is modified without needing another field. For instance, in that example:

class Foo {
    var myProperty: Int = 0 {
        didSet {
            print("The value of myProperty changed from \(oldValue) to \(myProperty)")
        }
    }
}

myProperty prints its old and new value every time it is modified. With just getters and setters, I would need this instead:

class Foo {
    var myPropertyValue: Int = 0
    var myProperty: Int {
        get { return myPropertyValue }
        set {
            print("The value of myProperty changed from \(myPropertyValue) to \(newValue)")
            myPropertyValue = newValue
        }
    }
}

So willSet and didSet represent an economy of a couple of lines, and less noise in the field list.

First off, when you call getElementById, you need to provide an id. o_O

The only item in your dom with an id is the table element. If you can, you could add ids (make sure they are unique) to your tr elements.

Alternatively, you can use getElementsByTagName('tr') to get a list of tr elements in your document, and then get the number of tds.

here is a fiddle that console logs the results...

int days = (int) (milliseconds / 86 400 000 )

Use the PHP function

void set_time_limit ( int $seconds )

The maximum execution time, in seconds. If set to zero, no time limit is imposed.

This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.

How does spring know which polymorphic type to use.

As long as there is only a single implementation of the interface and that implementation is annotated with @Component with Spring's component scan enabled, Spring framework can find out the (interface, implementation) pair. If component scan is not enabled, then you have to define the bean explicitly in your application-config.xml (or equivalent spring configuration file).

Do I need @Qualifier or @Resource?

Once you have more than one implementation, then you need to qualify each of them and during auto-wiring, you would need to use the @Qualifier annotation to inject the right implementation, along with @Autowired annotation. If you are using @Resource (J2EE semantics), then you should specify the bean name using the name attribute of this annotation.

Why do we autowire the interface and not the implemented class?

Firstly, it is always a good practice to code to interfaces in general. Secondly, in case of spring, you can inject any implementation at runtime. A typical use case is to inject mock implementation during testing stage.

interface IA
{
  public void someFunction();
}


class B implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someBfunc()
  {
     //doing b things
  }
}


class C implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someCfunc()
  {
     //doing C things
  }
}

class MyRunner
{
     @Autowire
     @Qualifier("b") 
     IA worker;

     ....
     worker.someFunction();
}

Your bean configuration should look like this:

<bean id="b" class="B" />
<bean id="c" class="C" />
<bean id="runner" class="MyRunner" />

Alternatively, if you enabled component scan on the package where these are present, then you should qualify each class with @Component as follows:

interface IA
{
  public void someFunction();
}

@Component(value="b")
class B implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someBfunc()
  {
     //doing b things
  }
}


@Component(value="c")
class C implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someCfunc()
  {
     //doing C things
  }
}

@Component    
class MyRunner
{
     @Autowire
     @Qualifier("b") 
     IA worker;

     ....
     worker.someFunction();
}

Then worker in MyRunner will be injected with an instance of type B.

Subtract -2 or -3 basis of removing last space also.

        String s = "apple car 05";
        System.out.println(s.substring(0, s.length() - 2));

Output

check pyplot docs. For completeness,

import numpy as np
import matplotlib.pyplot as plt

#evenly sampled time at 200ms intervals
t = np.arange(0., 5., 0.2)

# red dashes, blue squares and green triangles
plt.plot(t, t, 'r--', t, t**2, 'bs', t, t**3, 'g^')
plt.show()

Use strpos to detect a ?. Since ? can only appear in the URL at the beginning of a query string, you know if its there get params already exist and you need to add params using &

function addGetParamToUrl(&$url, $varName, $value)
{
    // is there already an ?
    if (strpos($url, "?"))
    {
        $url .= "&" . $varName . "=" . $value; 
    }
    else
    {
        $url .= "?" . $varName . "=" . $value;
    }
}

Because it's the size of an instance of the type - presumably enum values are stored as (32-bit / 4-byte) ints here.

You have to use the didSelectRow delegate method, because a UIPickerView can have an arbitrary number of components. There is no "objectValue" or anything like that, because that's entirely up to you.

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

I like the build-in pathlib libary because of quick options like directory= Path.cwd() Together with opencv it's quite easy to read pngs to numpy arrays. In this example you can even check the prefix of the image.

from pathlib import Path
import cv2
prefix = "p00"
suffix = ".png"
directory= Path.cwd()
file_names= [subp.name for subp in directory.rglob('*') if  (prefix in subp.name) & (suffix == subp.suffix)]
file_names.sort()
print(file_names)

all_frames= []
for file_name in file_names:
    file_path = str(directory / file_name)
    frame=cv2.imread(file_path)
    all_frames.append(frame)
print(type(all_frames[0]))
print(all_frames[0] [1][1])

Output:

['p000.png', 'p001.png', 'p002.png', 'p003.png', 'p004.png', 'p005.png', 'p006.png', 'p007.png', 'p008.png', 'p009.png']
<class 'numpy.ndarray'>

Just tell request that you are using json:true and forget about header and parse

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'GET',
    json:true
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

and the same for post

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'POST',
    json: {"name":"John", "lastname":"Doe"}
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

String name = android.os.Build.USER;

if (!TextUtils.isEmpty(name)) {
    nameEdit.setText(name);
}

in my case the problem was the Resource statement in the user access policy.

First we had "Resource": "arn:aws:s3:::BUCKET_NAME", but in order to have access to objects within a bucket you need a /* at the end: "Resource": "arn:aws:s3:::BUCKET_NAME/*"

From the AWS documentation:

Bucket access permissions specify which users are allowed access to the objects in a bucket and which types of access they have. Object access permissions specify which users are allowed access to the object and which types of access they have. For example, one user might have only read permission, while another might have read and write permissions.

Polymorphism is the ability to treat a class of object as if it is the parent class.

For instance, suppose there is a class called Animal, and a class called Dog that inherits from Animal. Polymorphism is the ability to treat any Dog object as an Animal object like so:

Dog* dog = new Dog;
Animal* animal = dog;

You could also Stub Consecutive Calls (#10 in 2.8.9 api). In this case, you would use multiple thenReturn calls or one thenReturn call with multiple parameters (varargs).

import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;

import org.junit.Before;
import org.junit.Test;

public class TestClass {

    private Foo mockFoo;

    @Before
    public void setup() {
        setupFoo();
    }

    @Test
    public void testFoo() {
        TestObject testObj = new TestObject(mockFoo);

        assertEquals(0, testObj.bar());
        assertEquals(1, testObj.bar());
        assertEquals(-1, testObj.bar());
        assertEquals(-1, testObj.bar());
    }

    private void setupFoo() {
        mockFoo = mock(Foo.class);

        when(mockFoo.someMethod())
            .thenReturn(0)
            .thenReturn(1)
            .thenReturn(-1); //any subsequent call will return -1

        // Or a bit shorter with varargs:
        when(mockFoo.someMethod())
            .thenReturn(0, 1, -1); //any subsequent call will return -1
    }
}

Create the script tag with a specific ID and then check if that ID exists?

Alternatively, loop through script tags checking for the script 'src' and make sure those are not already loaded with the same value as the one you want to avoid ?

Edit: following feedback that a code example would be useful:

(function(){
    var desiredSource = 'https://sitename.com/js/script.js';
    var scripts       = document.getElementsByTagName('script');
    var alreadyLoaded = false;

    if(scripts.length){
        for(var scriptIndex in scripts) {
            if(!alreadyLoaded && desiredSource === scripts[scriptIndex].src) {
                alreadyLoaded = true;
            }
        }
    }
    if(!alreadyLoaded){
        // Run your code in this block?
    }
})();

As mentioned in the comments (https://stackoverflow.com/users/1358777/alwin-kesler), this may be an alternative (not benchmarked):

(function(){
    var desiredSource = 'https://sitename.com/js/script.js';
    var scripts = document.getElementsByTagName('script');
    var alreadyLoaded = false;

    for(var scriptIndex in document.scripts) {
        if(!alreadyLoaded && desiredSource === scripts[scriptIndex].src) {
            alreadyLoaded = true;
        }
    }
    if(!alreadyLoaded){
        // Run your code in this block?
    }
})();

If you don't want to loop, there's no way to do it with Arrays. You should use a Set instead.

require 'set'
s = Set.new
100.times{|i| s << "foo#{i}"}
s.include?("foo99")
 => true
[1,2,3,4,5,6,7,8].to_set.include?(4) 
  => true

Sets work internally like Hashes, so Ruby doesn't need to loop through the collection to find items, since as the name implies, it generates hashes of the keys and creates a memory map so that each hash points to a certain point in memory. The previous example done with a Hash:

fake_array = {}
100.times{|i| fake_array["foo#{i}"] = 1}
fake_array.has_key?("foo99")
  => true

The downside is that Sets and Hash keys can only include unique items and if you add a lot of items, Ruby will have to rehash the whole thing after certain number of items to build a new map that suits a larger keyspace. For more about this, I recommend you watch "MountainWest RubyConf 2014 - Big O in a Homemade Hash by Nathan Long".

Here's a benchmark:

require 'benchmark'
require 'set'

array = []
set   = Set.new

10_000.times do |i|
  array << "foo#{i}"
  set   << "foo#{i}"
end

Benchmark.bm do |x|
  x.report("array") { 10_000.times { array.include?("foo9999") } }
  x.report("set  ") { 10_000.times { set.include?("foo9999")   } }
end

And the results:

      user     system      total        real
array  7.020000   0.000000   7.020000 (  7.031525)
set    0.010000   0.000000   0.010000 (  0.004816)

Not just tab icons, notification and launcher lives an app. I was confused about the sizes of the other icons used for different situations in the app.

I'm using 32px mdpi (Action Bar icons) dimensions and I cannot say if it would be correct.

We can animate images in ios 5 using this simple code.

CGRect imageFrame = imageView.frame;
imageFrame.origin.y = self.view.bounds.size.height;

[UIView animateWithDuration:0.5
    delay:1.0
    options: UIViewAnimationCurveEaseOut
    animations:^{
        imageView.frame = imageFrame;
    } 
    completion:^(BOOL finished){
        NSLog(@"Done!");
    }];

For archlinux/manjaro:

sudo pacman -S unixodbc

then:

sudo pip install pyodbc

or:

pip install pyodbc

You can upgrade your pip wheel setuptools before installing pyodbc (it won't affect the pyodbc installation) also with:

sudo python -m pip install --upgrade pip wheel setuptools

or

python -m pip install --upgrade pip wheel setuptools

echo $this->db->select('title, content, date')->get_compiled_select();

SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.

As it happens, you are close. Just need leading+trailing wildcards and move the NOT

 WHERE whatever NOT LIKE '%[a-z0-9]%'

Use sessions

On your search.jsp

Put your scard in sessions using session.setAttribute("scard","scard")

//the 1st variable is the string name that you will retrieve in ur next page,and the 2nd variable is the its value,i.e the scard value.

And in your next page you retrieve it using session.getAttribute("scard")

UPDATE

<input type="text" value="<%=session.getAttribute("scard")%>"/>

The problem is that you are trying to insert data into the database without using columns. Sql server gives you that error message.

error: insert into users values('1', '2','3') - this works fine as long you only have 3 columns

if you have 4 columns but only want to insert into 3 of them

correct: insert into users (firstName,lastName,city) values ('Tom', 'Jones', 'Miami')

hope this helps

clear && printf '\e[3J'

clears out everything, and it works well on OS X as well. Very neat.

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

2015 answer: according to UI Events, you can use the relatedTarget property of the event:

Used to identify a secondary EventTarget related to a Focus event, depending on the type of event.

For blur events,

relatedTarget: event target receiving focus.

Example:

function blurListener(event) {_x000D_
  event.target.className = 'blurred';_x000D_
  if(event.relatedTarget)_x000D_
    event.relatedTarget.className = 'focused';_x000D_
}_x000D_
[].forEach.call(document.querySelectorAll('input'), function(el) {_x000D_
  el.addEventListener('blur', blurListener, false);_x000D_
});

.blurred { background: orange }_x000D_
.focused { background: lime }

<p>Blurred elements will become orange.</p>_x000D_
<p>Focused elements should become lime.</p>_x000D_
<input /><input /><input />

Note Firefox won't support relatedTarget until version 48 (bug 962251, MDN).

Because you're using php-fpm, you should make sure that php-fpm user is the same as nginx user.

Check /etc/php-fpm.d/www.conf and set php user and group to nginx if it's not.

The php-fpm user needs write permission.

One point: you have to set NumberFormat property BEFORE loading the value into the cell. I had a nine digit number that still displayed as 9.14E+08 when the NumberFormat was set after the cell was loaded. Setting the property before loading the value made the number appear as I wanted, as straight text.

OR:

Could you try an autofit first:

Excel_Obj.Columns("A:V").EntireColumn.AutoFit

Cache the query in a global variable when it is not available.

Create a webpage to force the cache to be reloaded when you update it.

Add a call to the reloading page into your deployment scripts.

Try out this as well. Your page will refresh every 10sec

<html>
 <head>

  <meta http-equiv="refresh" content="10; url="<?php echo $_SERVER['PHP_SELF']; ?>">
 </head>
 <body>

 </body>

I hope the following sequence of code will help you:

Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight, config);
Canvas canvas = new Canvas(targetBitmap);
Matrix matrix = new Matrix();
matrix.setRotate(mRotation,source.getWidth()/2,source.getHeight()/2);
canvas.drawBitmap(source, matrix, new Paint());

If you check the following method from ~frameworks\base\graphics\java\android\graphics\Bitmap.java

public static Bitmap createBitmap(Bitmap source, int x, int y, int width, int height,
        Matrix m, boolean filter)

this would explain what it does with rotation and translate.

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

Atom has a built-in line ending selector package

More details here: https://github.com/atom/line-ending-selector

yes, of course! in fact, writing if(pointer) is a more convenient way of writing rather than if(pointer != NULL) because: 1. it is easy to debug 2. easy to understand 3. if accidently, the value of NULL is defined, then also the code will not crash

driver.find_element_by_id("some_id").size() is class method.

What we need is :

driver.find_element_by_id("some_id").size which is dictionary so :

if driver.find_element_by_id("some_id").size['width'] != 0 : print 'button exist'

Depending on whether you want to change all the identical links to something else or you want control over just the ones in a given section of the page or each one individually, you could do one of these.

Change all links to Google so they point to Google Maps:

<a href="http://www.google.com">

$("a[href='http://www.google.com/']").attr('href', 
'http://maps.google.com/');

To change links in a given section, add the container div's class to the selector. This example will change the Google link in the content, but not in the footer:

<div class="content">
    <p>...link to <a href="http://www.google.com/">Google</a>
    in the content...</p>
</div>

<div class="footer">
    Links: <a href="http://www.google.com/">Google</a>
</div>

$(".content a[href='http://www.google.com/']").attr('href', 
'http://maps.google.com/');

To change individual links regardless of where they fall in the document, add an id to the link and then add that id to the selector. This example will change the second Google link in the content, but not the first one or the one in the footer:

<div class="content">
    <p>...link to <a href="http://www.google.com/">Google</a>
    in the content...</p>
    <p>...second link to <a href="http://www.google.com/" 
        id="changeme">Google</a>
    in the content...</p>
</div>

<div class="footer">
    Links: <a href="http://www.google.com/">Google</a>
</div>

$("a#changeme").attr('href', 
'http://maps.google.com/');

I had the same issue and used a combination of the above solutions (and added a twist of my own). Note that I had to specify column widths to keep them consistent between header and body.

In my solution, the header and footer stay fixed while the body scrolls.

<div class="table-responsive">
    <table class="table table-striped table-hover table-condensed">

And then just applied the following CSS:

.bodycontainer { max-height: 450px; width: 100%; margin: 0; overflow-y: auto; }
.table-scrollable { margin: 0; padding: 0; }

I hope this helps someone else.

Include servlet-api.jar from your server lib folder.

Do this step

I had a similar issue when deploying from OSx on my local to my Linux live site.

It ran fine on OSx, but on Linux I was getting:

An Error Was Encountered

Unable to load the requested class: Ckeditor

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

Under Windows 7, open the Event Viewer. You can do this the way Gishu suggested for XP, typing eventvwr from the command line, or by opening the Control Panel, selecting System and Security, then Administrative Tools and finally Event Viewer. It may require UAC approval or an admin password.

In the left pane, expand Windows Logs and then System. You can filter the logs with Filter Current Log... from the Actions pane on the right and selecting "Service Control Manager." Or, depending on why you want this information, you might just need to look through the Error entries.

The actual log entry pane (not shown) is pretty user-friendly and self-explanatory. You'll be looking for messages like the following:

"The Praxco Assistant service entered the stopped state."
"The Windows Image Acquisition (WIA) service entered the running state."
"The MySQL service terminated unexpectedly. It has done this 3 time(s)."

Try:

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]

The + operator is overridden in python to concatenate strings.

On top of what the others have already stated, some sort of server-side scripting is necessary in order for the server to read and save the file.

Using PHP might be a good choice, but you're free to use any server-side scripting language. http://www.w3schools.com/php/php_file_upload.asp may be of use on that end.

string.Join("", (from i in arr select i.ToString()).ToArray())

In the .NET 4.0 the string.Join can use an IEnumerable<string> directly:

string.Join("", from i in arr select i.ToString())

in my case /**/.idea/* works well

U can do it easier than this answers :

Uri Selected_Image_Uri = data.getData();
ImageView imageView = (ImageView) findViewById(R.id.loadedimg);
imageView.setImageURI(Selected_Image_Uri);

This works for anonymous types, ExpandoObject, Nancy.DynamicDictionary or anything else that can be cast to IDictionary<string, object>.

    public static bool PropertyExists(dynamic obj, string name) {
        if (obj == null) return false;
        if (obj is IDictionary<string, object> dict) {
            return dict.ContainsKey(name);
        }
        return obj.GetType().GetProperty(name) != null;
    }

I my case, I just added ejs manually in package.json:

 {
   "name": "myApp"
   "dependencies": {
     "express": "^4.12.2",
     "ejs": "^1.0.0"
   }
 }

And run npm install (may be you need run it with sudo) Please note, that ejs looks views directory by default

If you are on a mac you can install haxm using homebrew via cask which is a built-in extension (as of 2015) which allows installing non-open-source and desktop apps (i.e. chrome, firefox, eclipse, etc.):

brew cask install intel-haxm 

Android Studio

If you are using Android Studio then you can achieve the same result from the menu Tools ? SDK Manager, and then on the SDK Tools tab, select the checkbox for Intel x86 Emulator Accelerator (HAXM installer), and click Ok.

Enter the image and give height:100%;width:auto then just change the height of navbar itself to resize image. There is a really good example in codepen. https://codepen.io/bootstrapped/pen/KwYGwq

Your attempt wasn't that bad. You have to do it with LIKE, yes.

In the manual it says:

Use LIKE to create an empty table based on the definition of another table, including any column attributes and indexes defined in the original table.

So you do:

CREATE TABLE New_Users  LIKE Old_Users;

Then you insert with

INSERT INTO New_Users SELECT * FROM Old_Users GROUP BY ID;

But you can not do it in one statement.

One option is to chain the -replace operations together. The ` at the end of each line escapes the newline, causing PowerShell to continue parsing the expression on the next line:

$original_file = 'path\filename.abc'
$destination_file =  'path\filename.abc.new'
(Get-Content $original_file) | Foreach-Object {
    $_ -replace 'something1', 'something1aa' `
       -replace 'something2', 'something2bb' `
       -replace 'something3', 'something3cc' `
       -replace 'something4', 'something4dd' `
       -replace 'something5', 'something5dsf' `
       -replace 'something6', 'something6dfsfds'
    } | Set-Content $destination_file

Another option would be to assign an intermediate variable:

$x = $_ -replace 'something1', 'something1aa'
$x = $x -replace 'something2', 'something2bb'
...
$x

Generate Unique ID Using Java

UUID is the fastest and easiest way to generate unique ID in Java.

import java.util.UUID;

public class UniqueIDTest {
  public static void main(String[] args) {
    UUID uniqueKey = UUID.randomUUID();
    System.out.println (uniqueKey);
  }
}

IMO, you should call it. If your superclass is object, you should not, but in other cases I think it is exceptional not to call it. As already answered by others, it is very convenient if your class doesn't even have to override __init__ itself, for example when it has no (additional) internal state to initialize.

For Windows slave, please use Execute Windows batch command.
For Unix-like slave like linux or Mac, Execute shell is the option.

This is just to mention entr as an alternative on OSX to run arbitrary commands when files change. I find it simple and useful.

This is a old question, but to me it still doesn't seem to have a complete answer to the OP's question. The chosen answer about security being the possible issue is actually often not the problem when using the Firefox 'Markdown Viewer' plug-in in my experience. Also, the OP seems to be using MS-Windows, so there is the added issue of specifying different drives.

So, here is a little more complete yet simple answer for the 'Markdown Viewer' plug-in on Windows (and other Markdown renderers I've seen): just enter the local path as you would normally, and if it is an absolute path make sure to start it with a slash. So:

[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)

That last one was probably what the OP was looking for given their example. Note this can also be used to display directories rather than files.

Though late, I hope this helps!

Well in fact TryGetValue is faster. How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.

Edit:

Ok, I understand your confusion so let me elaborate:

Case 1:

if (myDict.Contains(someKey))
     someVal = myDict[someKey];

In this case there are 2 calls to FindEntry, one to check if the key exists and one to retrieve it

Case 2:

myDict.TryGetValue(somekey, out someVal)

In this case there is only one call to FindKey because the resulting index is kept for the actual retrieval in the same method.

Apparently anonymous functions cannot be serialized.

Example

$function = function () {
    return "ABC";
};
serialize($function); // would throw error

From your code you are using Closure:

$callback = function () // <---------------------- Issue
{
    return 'ZendMail_' . microtime(true) . '.tmp';
};

Solution 1 : Replace with a normal function

Example

function emailCallback() {
    return 'ZendMail_' . microtime(true) . '.tmp';
}
$callback = "emailCallback" ;

Solution 2 : Indirect method call by array variable

If you look at http://docs.mnkras.com/libraries_23rdparty_2_zend_2_mail_2_transport_2file_8php_source.html

   public function __construct($options = null)
   63     {
   64         if ($options instanceof Zend_Config) {
   65             $options = $options->toArray();
   66         } elseif (!is_array($options)) {
   67             $options = array();
   68         }
   69 
   70         // Making sure we have some defaults to work with
   71         if (!isset($options['path'])) {
   72             $options['path'] = sys_get_temp_dir();
   73         }
   74         if (!isset($options['callback'])) {
   75             $options['callback'] = array($this, 'defaultCallback'); <- here
   76         }
   77 
   78         $this->setOptions($options);
   79     }

You can use the same approach to send the callback

$callback = array($this,"aMethodInYourClass");

Extending Richard Cook's answer.

Here's the ant task to run any program (including, but not limited to Java programs):

<target name="run">
   <exec executable="name-of-executable">
      <arg value="${arg0}"/>
      <arg value="${arg1}"/>
   </exec>
</target>

Here's the task to run a Java program from a .jar file:

<target name="run-java">
   <java jar="path for jar">
      <arg value="${arg0}"/>
      <arg value="${arg1}"/>
   </java>
</target>

You can invoke either from the command line like this:

ant -Darg0=Hello -Darg1=World run

Make sure to use the -Darg syntax; if you ran this:

ant run arg0 arg1

then ant would try to run targets arg0 and arg1.

Using a great similar service

private string GetPublicIpAddress()
{
    var request = (HttpWebRequest)WebRequest.Create("http://ifconfig.me");

    request.UserAgent = "curl"; // this will tell the server to return the information as if the request was made by the linux "curl" command

    string publicIPAddress;

    request.Method = "GET";
    using (WebResponse response = request.GetResponse())
    {
        using (var reader = new StreamReader(response.GetResponseStream()))
        {
            publicIPAddress = reader.ReadToEnd();
        }
    }

    return publicIPAddress.Replace("\n", "");
}

Make sure that the directory containing the private key files is set to 700

chmod 700 ~/.ec2

You can also use GO + how many times you want to execute the same query.

DELETE TOP (10000)  [TARGETDATABASE].[SCHEMA].[TARGETTABLE] 
WHERE readTime < dateadd(MONTH,-1,GETDATE());
-- how many times you want the query to repeat
GO 100

You can use:

var tomorrow = new Date();
tomorrow.setDate(new Date().getDate()+1);

For example, since there are 30 days in April, the following code will output May 1:

var day = new Date('Apr 30, 2000');
console.log(day); // Apr 30 2000

var nextDay = new Date(day);
nextDay.setDate(day.getDate() + 1);
console.log(nextDay); // May 01 2000    

See fiddle.

That REALLY depends on what you need that bash script to do!

For example, if the bash script just echoes some output, you could just do

docker run --rm -v $(pwd)/mybashscript.sh:/mybashscript.sh ubuntu bash /mybashscript.sh

Another possibility is that you want the bash script to install some software- say the script to install docker-compose. you could do something like

docker run --rm -v /usr/bin:/usr/bin --privileged -v $(pwd)/mybashscript.sh:/mybashscript.sh ubuntu bash /mybashscript.sh

But at this point you're really getting into having to know intimately what the script is doing to allow the specific permissions it needs on your host from inside the container.

Use and empty() whit negation (for test if not empty)

if(!empty($_GET['id'])) {
    // if get id is not empty
}

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

@PathVariable is used to tell Spring that part of the URI path is a value you want passed to your method. Is this what you want, or are the variables supposed to be form data posted to the URI?

If you want form data, use @RequestParam instead of @PathVariable.

If you want @PathVariable, you need to specify placeholders in the @RequestMapping entry to tell Spring where the path variables fit in the URI. For example, if you want to extract a path variable called contentId, you would use:

@RequestMapping(value = "/whatever/{contentId}", method = RequestMethod.POST)

Edit: Additionally, if your path variable could contain a '.' and you want that part of the data, then you will need to tell Spring to grab everything, not just the stuff before the '.':

@RequestMapping(value = "/whatever/{contentId:.*}", method = RequestMethod.POST)

This is because the default behaviour of Spring is to treat that part of the URL as if it is a file extension, and excludes it from variable extraction.

I had the same issue, but came up with a different solution:

If you make the column or the whole grid "Read Only" so that when the user clicks the checkbox it doesn't change value.

Fortunately, the DataGridView.CellClick event is still fired. In my case I do the following in the cellClick event:

if (jM_jobTasksDataGridView.Columns[e.ColumnIndex].CellType.Name == "DataGridViewCheckBoxCell")

But you could check the column name if you have more than one checkbox column.

I then do all the modification / saving of the dataset myself.

It's very easy for Kotlin!

listToBeSorted.sortBy { it.distance }

Here :)

function isSet(iVal){
 return (iVal!=="" && iVal!=null && iVal!==undefined && typeof(iVal) != "undefined") ? 1 : 0;
} // Returns 1 if set, 0 false

Suppose you have a numpy array

 arr = numpy.arange(10000).reshape(250,40)

If you want to print the full array in a one-off way (without toggling np.set_printoptions), but want something simpler (less code) than the context manager, just do

for row in arr:
     print row 

I think you have to store the number on heap. The int ret variable was on stack and was destructed at the end of execution of function myThread.

void *myThread()
{
       int *ret = malloc(sizeof(int));
       if (ret == NULL) {
           // ...
       }
       *ret = 42;
       pthread_exit(ret);
}

Don't forget to free it when you don't need it :)

Another solution is to return the number as value of the pointer, like Neil Butterworth suggests.

While correct that this will work:

TimeSpan time = TimeSpan.Parse("07:35");

And if you are using it for validation...

TimeSpan time;
if (!TimeSpan.TryParse("07:35", out time))
{
    // handle validation error
}

Consider that TimeSpan is primarily intended to work with elapsed time, rather than time-of-day. It will accept values larger than 24 hours, and will accept negative values also.

If you need to validate that the input string is a valid time-of-day (>= 00:00 and < 24:00), then you should consider this instead:

DateTime dt;
if (!DateTime.TryParseExact("07:35", "HH:mm", CultureInfo.InvariantCulture, 
                                              DateTimeStyles.None, out dt))
{
    // handle validation error
}
TimeSpan time = dt.TimeOfDay;

As an added benefit, this will also parse 12-hour formatted times when an AM or PM is included, as long as you provide the appropriate format string, such as "h:mm tt".

Try this.

CSS

.imageContainer {
    float: left;
}

p {
    text-align: center;
}

HTML

<div class="image123">
    <div class="imageContainer">
        <img src="/images/tv.gif" height="200" width="200" />
        <p>This is image 1</p>
    </div>
    <div class="imageContainer">
        <img class="middle-img" src="/images/tv.gif"/ height="200" width="200" />
        <p>This is image 2</p>
    </div>
    <div class="imageContainer">    
        <img src="/images/tv.gif"/ height="200" width="200"/>
        <p>This is image 3</p>
    </div>
</div>

Well you could directly substract from the value by just referencing the key. Which in my opinion is simpler.

>>> books = {}
>>> books['book'] = 3       
>>> books['book'] -= 1   
>>> books   
{'book': 2}   

In your case:

book_shop[ch1] -= 1

You set an element's id by setting its corresponding property:

myPara.id = ID;

The following script would obtain the ci.jenkins-ci.org public key certificate in base64-encoded DER format and convert it to an OpenSSH public key file. This code assumes that a 2048-bit RSA key is used and draws a lot from this Ian Boyd's answer. I've explained a bit more how it works in comments to this article in Jenkins wiki.

echo -n "ssh-rsa " > jenkins.pub
curl -sfI https://ci.jenkins-ci.org/ | grep -i X-Instance-Identity | tr -d \\r | cut -d\  -f2 | base64 -d | dd bs=1 skip=32 count=257 status=none | xxd -p -c257 | sed s/^/00000007\ 7373682d727361\ 00000003\ 010001\ 00000101\ / | xxd -p -r | base64 -w0 >> jenkins.pub
echo >> jenkins.pub

else if (isset($_GET['actie']) && $_GET['actie']== "aanmelden"){

    $username= $_POST['username'];
    $password= md5($_POST['password']);
    $query = "SELECT password FROM tbl WHERE username = '$username'";
    $result= mysql_query($query);
    $row= mysql_fetch_array($result);

    if($password == $row['password']){
            session_start();
            $_SESSION['logged in'] = true;
            echo "Logged in";

    }
}

For me, once there was a mistake in spelling of function

For e.g. instead of

$(document).ready(function(){

});

I wrote

$(document).ready(funciton(){

});

So keep that also in check

In a nutshell, no.

However, there are "nice" things you can do.

1. Run a profiler trace with, say, the stored proc name
2. Add a line each proc (create a tabel of course)
   • "INSERT dbo.SPCall (What, When) VALUES (OBJECT_NAME(@@PROCID), GETDATE()"
3. Extend 2 with duration too

There are "fun" things you can do:

1. Remove it, see who calls
2. Remove rights, see who calls
3. Add RAISERROR ('Warning: pwn3d: call admin', 16, 1), see who calls
4. Add WAITFOR DELAY '00:01:00', see who calls

You get the idea. The tried-and-tested "see who calls" method of IT support.

If the reports are Reporting Services, then you can mine the RS database for the report runs if you can match code to report DataSet.

You couldn't rely on DMVs anyway because they are reset om SQL Server restart. Query cache/locks are transient and don't persist for any length of time.

I would:

if only because then it's "in" a database, and not "just" a file. Easier to work with, to my mind.

Subscribing to the belief that others have worked this problem out already. If you prefer, no doubt eXist might even be "better" at formatting xml, or as good.

You can always query the data various different ways, of course. I kept it as simple as possible. You can just use a GUI, too, but you specified console.

import urllib2

try:
    fileHandle = urllib2.urlopen('http://www.python.org/fish.html')
    data = fileHandle.read()
    fileHandle.close()
except urllib2.URLError, e:
    print 'you got an error with the code', e

You can also use pyautogui as:

import pyautogui
pyautogui._autoPause(0.05, False)

If the first argument is not None, then it will pause for first argument's seconds, in this example: 0.05 seconds

If the first argument is None, and the second argument is True, then it will sleep for the global pause setting which is set with:

pyautogui.PAUSE = int

If you are wondering about the reason, see the source code:

def _autoPause(pause, _pause):
    """If `pause` is not `None`, then sleep for `pause` seconds.
    If `_pause` is `True`, then sleep for `PAUSE` seconds (the global pause setting).

    This function is called at the end of all of PyAutoGUI's mouse and keyboard functions. Normally, `_pause`
    is set to `True` to add a short sleep so that the user can engage the failsafe. By default, this sleep
    is as long as `PAUSE` settings. However, this can be override by setting `pause`, in which case the sleep
    is as long as `pause` seconds.
    """
    if pause is not None:
        time.sleep(pause)
    elif _pause:
        assert isinstance(PAUSE, int) or isinstance(PAUSE, float)
        time.sleep(PAUSE)

insert byte to specific place.

insertToArray(arr,index,item) {
   return Buffer.concat([arr.slice(0,index),Buffer.from(item,"utf-8"),arr.slice(index)]);
}

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

something like this:

$('#image').show();
$.ajax({
    url: uri,
    cache: false,
    success: function(html){
       $('.info').append(html);
       $('#image').hide();
    }
});

If your if statement is in Loop You can use

 break; 

If you want to escape some code & continue to loop Use :

continue;

If your if statement not in Loop You can use :

 return 0;

Or 




  exit();

I am assuming that you have enough permissions to create this directory.

To fix your problem, you can either ssh to some other location:

ssh [email protected]

and accept new key - it will create directory ~/.ssh and known_hosts underneath, or simply create it manually using

mkdir ~/.ssh
chmod 700 ~/.ssh

Note that chmod 700 is an important step!

After that, ssh-keygen should work without complaints.

No need to care of whether before/after this digit having other type of words

To just match the pattern of 5 digits number anywhere in the string, no matter it is separated by space or not, use this regular expression (?<!\d)\d{5}(?!\d).

Sample JavaScript codes:

var regexp = new RegExp(/(?<!\d)\d{5}(?!\d)/g); 
    var matches = yourstring.match(regexp);
    if (matches && matches.length > 0) {
        for (var i = 0, len = matches.length; i < len; i++) {
            // ... ydo something with matches[i] ...
        } 
    }

Here's some quick results.

• abc12345xyz (?)

• 12345abcd (?)

• abcd12345 (?)

• 0000aaaa2 (?)

• a1234a5 (?)

• 12345 (?)

• <space>12345<space>12345 (??)

While you cannot modify a column as such, you may operate on a column and return a new DataFrame reflecting that change. For that you'd first create a UserDefinedFunction implementing the operation to apply and then selectively apply that function to the targeted column only. In Python:

from pyspark.sql.functions import UserDefinedFunction
from pyspark.sql.types import StringType

name = 'target_column'
udf = UserDefinedFunction(lambda x: 'new_value', StringType())
new_df = old_df.select(*[udf(column).alias(name) if column == name else column for column in old_df.columns])

new_df now has the same schema as old_df (assuming that old_df.target_column was of type StringType as well) but all values in column target_column will be new_value.

Simple way is to use curl from command-line, for example:

DATA="foo=bar&baz=qux"
curl --data "$DATA" --request POST --header "Content-Type:application/x-www-form-urlencoded" http://example.com/api/callback | python -m json.tool

or here is example how to send raw POST request using Bash shell (JSON request):

exec 3<> /dev/tcp/example.com/80

DATA='{"email": "[email protected]"}'
LEN=$(printf "$DATA" | wc -c)

cat >&3 << EOF
POST /api/retrieveInfo HTTP/1.1
Host: example.com
User-Agent: Bash
Accept: */*
Content-Type:application/json
Content-Length: $LEN
Connection: close

$DATA
EOF

# Read response.
while read line <&3; do
   echo $line
done

The best is QSpinBox.

And for a double value use QDoubleSpinBox.

QSpinBox myInt;
myInt.setMinimum(-5);
myInt.setMaximum(5);
myInt.setSingleStep(1);// Will increment the current value with 1 (if you use up arrow key) (if you use down arrow key => -1)
myInt.setValue(2);// Default/begining value
myInt.value();// Get the current value
//connect(&myInt, SIGNAL(valueChanged(int)), this, SLOT(myValueChanged(int)));

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

This is probably not the most efficient way to turn a list to map, but it makes the calling code more readable. I used implicit conversions to add a mapBy method to List:

implicit def list2ListWithMapBy[T](list: List[T]): ListWithMapBy[T] = {
  new ListWithMapBy(list)
}

class ListWithMapBy[V](list: List[V]){
  def mapBy[K](keyFunc: V => K) = {
    list.map(a => keyFunc(a) -> a).toMap
  }
}

Calling code example:

val list = List("A", "AA", "AAA")
list.mapBy(_.length)                  //Map(1 -> A, 2 -> AA, 3 -> AAA)

Note that because of the implicit conversion, the caller code needs to import scala's implicitConversions.

How do I round this down to, say, 1.543 when I print totalWorkTimeInHours?

To round totalWorkTimeInHours to 3 digits for printing, use the String constructor which takes a format string:

print(String(format: "%.3f", totalWorkTimeInHours))

string trim(const string & sStr)
{
    int nSize = sStr.size();
    int nSPos = 0, nEPos = 1, i;
    for(i = 0; i< nSize; ++i) {
        if( !isspace( sStr[i] ) ) {
            nSPos = i ;
            break;
        }
    }
    for(i = nSize -1 ; i >= 0 ; --i) {
        if( !isspace( sStr[i] ) ) {
            nEPos = i;
            break;
        }
    }
    return string(sStr, nSPos, nEPos - nSPos + 1);
}

Using java 1.7, on UNIX -

java -cp myjar.jar:lib/*:. mypackage.MyClass

On Windows you need to use ';' instead of ':' -

java -cp myjar.jar;lib/*;. mypackage.MyClass

when you use postfix it instantiates on more object in memory. Some people say that it is better to use suffix operator in for loop

Here's what the JDK API says about AbstractMethodError:

Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

Bug in the oracle driver, maybe?

This is by far the best post for exporting to excel from SQL:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926

To quote from user madhivanan,

Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel

Create an Excel file named testing having the headers same as that of table columns and use these queries

1 Export data to existing EXCEL file from SQL Server table

insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;', 
    'SELECT * FROM [SheetName$]') select * from SQLServerTable

2 Export data from Excel to new SQL Server table

select * 
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [Sheet1$]')

3 Export data from Excel to existing SQL Server table (edited)

Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [SheetName$]')

4 If you dont want to create an EXCEL file in advance and want to export data to it, use

EXEC sp_makewebtask 
    @outputfile = 'd:\testing.xls', 
    @query = 'Select * from Database_name..SQLServerTable', 
    @colheaders =1, 
    @FixedFont=0,@lastupdated=0,@resultstitle='Testing details'

(Now you can find the file with data in tabular format)

5 To export data to new EXCEL file with heading(column names), create the following procedure

create procedure proc_generate_excel_with_columns
(
    @db_name    varchar(100),
    @table_name varchar(100),   
    @file_name  varchar(100)
)
as

--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select 
    @columns=coalesce(@columns+',','')+column_name+' as '+column_name 
from 
    information_schema.columns
where 
    table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')

--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'

--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)

--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)

--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)

--Delete dummy file 
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)

After creating the procedure, execute it by supplying database name, table name and file path:

EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'

Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.

Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.

To update single cells

A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?

This is the principle of how you do manage that

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99

You can also add formulas to Excel using this:

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'

Exporting with column names using T-SQL

Member Mladen Prajdic also has a blog entry on how to do this here

References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this

Errors that may occur

If you get the following error:

OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries

Then run this:

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

Something like this might work:

$("body").attr("class", "about");

It uses jQuery's attr() to add the class 'about' to the body.

You can overload the method with different parameters:

public int doSomething(int arg1, int arg2)
{
//some logic here
        return 0;
}

public int doSomething(
{
doSomething(0,0)
}

The long-term answer is that all output from your PHP scripts should be buffered in variables. This includes headers and body output. Then at the end of your scripts do any output you need.

The very quick fix for your problem will be to add

ob_start();

as the very first thing in your script, if you only need it in this one script. If you need it in all your scripts add it as the very first thing in your header.php file.

This turns on PHP's output buffering feature. In PHP when you output something (do an echo or print) it has to send the HTTP headers at that time. If you turn on output buffering you can output in the script but PHP doesn't have to send the headers until the buffer is flushed. If you turn it on and don't turn it off PHP will automatically flush everything in the buffer after the script finishes running. There really is no harm in just turning it on in almost all cases and could give you a small performance increase under some configurations.

If you have access to change your php.ini configuration file you can find and change or add the following

output_buffering = On

This will turn output buffering out without the need to call ob_start().

To find out more about output buffering check out http://php.net/manual/en/book.outcontrol.php

There may not be anything 'Python specific', but the KDE and GNOME desktops offer text-to-speech as a part of their accessibility support, and also offer python library bindings. It may be possible to use the python bindings to control the desktop libraries for text to speech.

If using the Jython implementation of Python on the JVM, the FreeTTS system may be usable.

Finally, OSX and Windows have native APIs for text to speech. It may be possible to use these from python via ctypes or other mechanisms such as COM.

http://docs.python.org/howto/unicode.html#the-unicode-type

str = unicode(str, errors='replace')

or

str = unicode(str, errors='ignore')

Note: This will strip out (ignore) the characters in question returning the string without them.

For me this is ideal case since I'm using it as protection against non-ASCII input which is not allowed by my application.

Alternatively: Use the open method from the codecs module to read in the file:

import codecs
with codecs.open(file_name, 'r', encoding='utf-8',
                 errors='ignore') as fdata:

I wrote this snippet, that I've been using for handling this exact case.

It's in plain javascript, making it also suitable in cases like with bootsrap5 without jQuery.

<script type='text/javascript'>
    window.onhashchange=hashTriggerTab;
    window.onload=hashTriggerTab;
    
    function hashTriggerTab(){
        var current_hash=window.location.hash;
        if(current_hash.substring(0,1)=='#')current_hash=current_hash.substring(1);
        if(current_hash!=''){
            var trigger=document.querySelector('.nav-tabs a[href="#'+current_hash+'"]');
            if(trigger)trigger.click();
        }
    }
</script>

With that in place, you could link both on the same page, like:

<a href='#tabId'>Link Any Tab</a>

Or from external page like:

<a href='newpage.php#tabId'>Link From External</a>

System.Web.HttpContext.Current.Server.MapPath("~/") gives null if we call it from a thread.

So, Try to use

System.Web.Hosting.HostingEnvironment.MapPath("~/")

Executive summary: it's 64 bits, or larger.

unsigned long long is the same as unsigned long long int. Its size is platform-dependent, but guaranteed by the C standard (ISO C99) to be at least 64 bits. There was no long long in C89, but apparently even MSVC supports it, so it's quite portable.

In the current C++ standard (issued in 2003), there is no long long, though many compilers support it as an extension. The upcoming C++0x standard will support it and its size will be the same as in C, so at least 64 bits.

You can get the exact size, in bytes (8 bits on typical platforms) with the expression sizeof(unsigned long long). If you want exactly 64 bits, use uint64_t, which is defined in the header <stdint.h> along with a bunch of related types (available in C99, C++11 and some current C++ compilers).

You should not wrap JavaScript expressions in quotes.

<option data-img-src={this.props.imageUrl} value="1">{this.props.title}</option>

Take a look at the JavaScript Expressions docs for more info.

Update from 09/2017

It is possible to develop iOS (and Android at the same time) application using React Native + Expo without owning a mac. You will also be able to run your iOS application within iOS Expo app while developing it. (You can even publish it for other people to access, but it will only run within Expo app). Here is page from Expo on how to generate standalone app.

Steps from that page:

One: Install exp by running npm install -g exp

Two: Configure app.json (somewhere along these lines):

{
   "expo": {
    "name": "Your App Name",
    "icon": "./path/to/your/app-icon.png",
    "version": "1.0.0",
    "slug": "your-app-slug",
    "sdkVersion": "17.0.0",
    "ios": {
      "bundleIdentifier": "com.yourcompany.yourappname"
    },
    "android": {
      "package": "com.yourcompany.yourappname"
    }
   }
 }

Three: Start exp packeger with exp start

Four: run exp build:android or exp build:ios.

You will be prompted for some input. For android you can choose 1) Let Expo handle the process! if you don't have keystore (or if you don't know what it is). For iOS you will have to enter your Apple developer credentials. Then you can provide distribution certificate or let expo handle it.

Five: Once in a while you will have to come back and run exp build:status command to check whether your build was complete. If complete you will be provided a direct link to .apk or .ipa file.

The only drawback to this approach is that it won't be as native as writing iOS app in Swift, and you will have to put up with parade of issues you may run into while developing with weakly typed js, npm, and it's dependency-on-particular-version-of-some-other-library issues, and other stuff.

If you only plan to work with one key in particular, you may accomplish this with a single line without having to store an array for all of the keys:

echo array_keys($array)[$i];

Image download with using image clicking!

I did this simple code!:)

<html>
<head>
<title> Download-Button </title>
</head>
<body>
<p> Click the image ! You can download! </p>
<a download="logo.png" href="http://localhost/folder/img/logo.png" title="Logo title">
<img alt="logo" src="http://localhost/folder/img/logo.png">
</a>
</body>
</html>

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

The two previous answers demonstrate how to use Canvas and ImageData. I would like to propose an answer with runnable example and using an image processing framework, so you don't need to handle the pixel data manually.

MarvinJ provides the method image.getAlphaComponent(x,y) which simply returns the transparency value for the pixel in x,y coordinate. If this value is 0, pixel is totally transparent, values between 1 and 254 are transparency levels, finally 255 is opaque.

For demonstrating I've used the image below (300x300) with transparent background and two pixels at coordinates (0,0) and (150,150).

Console output:

(0,0): TRANSPARENT
(150,150): NOT_TRANSPARENT

image = new MarvinImage();_x000D_
image.load("https://i.imgur.com/eLZVbQG.png", imageLoaded);_x000D_
_x000D_
function imageLoaded(){_x000D_
  console.log("(0,0): "+(image.getAlphaComponent(0,0) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
  console.log("(150,150): "+(image.getAlphaComponent(150,150) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
}

<script src="https://www.marvinj.org/releases/marvinj-0.7.js"></script>

or this, I did not implement the array comparison so you will also have some fun :)

public bool CompareTables(DataTable a, DataTable b)
{
    if(a.Rows.Count != b.Rows.Count)
    {
        // different size means different tables
        return false;
    }

    for(int rowIndex=0; rowIndex<a.Rows.Count; ++rowIndex)
    {
        if(!arraysHaveSameContent(a.Rows[rowIndex].ItemArray, b.Rows[rowIndex].ItemArray,))
        {
            return false;
        }
    }

    // Tables have same data
    return true;
}

private bool arraysHaveSameContent(object[] a, object[] b)
{
    // Here your super cool method to compare the two arrays with LINQ,
    // or if you are a loser do it with a for loop :D
}

Open Eclipse, navigate to Window -> Preferences -> Java -> Code Style -> Code Templates -> Comments -> Types and then press the 'Edit' button. There you can change your name in the generated comment from @Author ${user} to @Author Rajish.

This is not a particularly good answer as it explains how to run your java code n VS Code and not necessarily a Maven project, but it worked for me because I could not get around to doing the manual configuration myself. I decided to use this method instead since it is easier and faster.

Install VSCode (and for windows, set your environment variables), then install vscode:extension/vscjava.vscode-java-pack as detailed above, and then install the code runner extension pack, which basically sets up the whole process (in the background) as explained in the accepted answer above and then provides a play button to run your java code when you're ready.

This was all explained in this video.

Again, this is not the best solution, but if you want to cut to the chase, you may find this answer useful.

Here the code i used for my app

This code will take a image from url and convert is to a byte array

byte[] logoImage = getLogoImage(IMAGEURL);

private byte[] getLogoImage(String url){
     try {
             URL imageUrl = new URL(url);
             URLConnection ucon = imageUrl.openConnection();

             InputStream is = ucon.getInputStream();
             BufferedInputStream bis = new BufferedInputStream(is);

             ByteArrayBuffer baf = new ByteArrayBuffer(500);
             int current = 0;
             while ((current = bis.read()) != -1) {
                  baf.append((byte) current);
             }

             return baf.toByteArray();
     } catch (Exception e) {
          Log.d("ImageManager", "Error: " + e.toString());
     }
     return null;
}

To save the image to db i used this code.

 public void insertUser(){
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        String delSql = "DELETE FROM ACCOUNTS";
        SQLiteStatement delStmt = db.compileStatement(delSql);
        delStmt.execute();

        String sql = "INSERT INTO ACCOUNTS (account_id,account_name,account_image) VALUES(?,?,?)";
        SQLiteStatement insertStmt = db.compileStatement(sql);
        insertStmt.clearBindings();
        insertStmt.bindString(1, Integer.toString(this.accId));
        insertStmt.bindString(2,this.accName);
        insertStmt.bindBlob(3, this.accImage);
        insertStmt.executeInsert();
        db.close();
}

To retrieve the image back this is code i used.

public Account getCurrentAccount() {
    SQLiteDatabase db = dbHelper.getWritableDatabase();
    String sql = "SELECT * FROM ACCOUNTS";
    Cursor cursor = db.rawQuery(sql, new String[] {});

    if(cursor.moveToFirst()){
        this.accId  = cursor.getInt(0);
        this.accName = cursor.getString(1);
        this.accImage = cursor.getBlob(2);
    }
    if (cursor != null && !cursor.isClosed()) {
        cursor.close();
    }
    db.close();
    if(cursor.getCount() == 0){
        return null;
    } else {
        return this;
    }
}

Finally to load this image to a imageview

logoImage.setImageBitmap(BitmapFactory.decodeByteArray( currentAccount.accImage, 
        0,currentAccount.accImage.length));

note - lepl is no longer supported, sorry (you're welcome to use it, and i think the code below works, but it's not going to get updates).

rfc 3696 http://www.faqs.org/rfcs/rfc3696.html defines how to do this (for http urls and email). i implemented its recommendations in python using lepl (a parser library). see http://acooke.org/lepl/rfc3696.html

to use:

>>> validator = HttpUrl()
>>> validator('google')
False
>>> validator('http://google')

try putting a delay on the last color fade.

What are valid values for the id attribute in HTML?
ID's cannot start with digits!!!

You're grouping with BillDate, but the bill dates are different for each account so your rows are not being grouped. If you think about it, that doesn't even make sense - they are different bills, and have different dates. The same goes for the Bill - you're attempting to sum bills for an account, why would you group by that?

If you leave BillDate and Bill off of the select and group by clauses you'll get the correct results.

SELECT AccountNumber, SUM(Bill)
FROM Table1
GROUP BY AccountNumber

Port:

A port can refer to a physical connection point for peripheral devices such as serial, parallel, and USB ports. The term port also refers to certain Ethernet connection points, s uch as those on a hub, switch, or router.

Socket:

A socket represents a single connection between two network applications. These two applications nominally run on different computers, but sockets can also be used for interprocess communication on a single computer. Applications can create multiple sockets for communicating with each other. Sockets are bidirectional, meaning that either side of the connection is capable of both sending and receiving data.

If you don't need these methods to return something, you could make them return Runnable objects.

private Runnable methodName (final int arg) {
    return (new Runnable() {
        public void run() {
          // do stuff with arg
        }
    });
}

Then use it like:

private void otherMethodName (Runnable arg){
    arg.run();
}

I’m using this:

<!-- language: c# -->
private static string wmiProperty(string wmiClass, string wmiProperty){
  using (var searcher = new ManagementObjectSearcher($"SELECT * FROM {wmiClass}")) {
   try {
                    IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
                    return objects.Select(x => x.GetPropertyValue(wmiProperty)).FirstOrDefault().ToString().Trim();
                } catch (NullReferenceException) {
                    return null;
                }
            }
        }

For a bandpass filter, ws is a tuple containing the lower and upper corner frequencies. These represent the digital frequency where the filter response is 3 dB less than the passband.

wp is a tuple containing the stop band digital frequencies. They represent the location where the maximum attenuation begins.

gpass is the maximum attenutation in the passband in dB while gstop is the attentuation in the stopbands.

Say, for example, you wanted to design a filter for a sampling rate of 8000 samples/sec having corner frequencies of 300 and 3100 Hz. The Nyquist frequency is the sample rate divided by two, or in this example, 4000 Hz. The equivalent digital frequency is 1.0. The two corner frequencies are then 300/4000 and 3100/4000.

Now lets say you wanted the stopbands to be down 30 dB +/- 100 Hz from the corner frequencies. Thus, your stopbands would start at 200 and 3200 Hz resulting in the digital frequencies of 200/4000 and 3200/4000.

To create your filter, you'd call buttord as

fs = 8000.0
fso2 = fs/2
N,wn = scipy.signal.buttord(ws=[300/fso2,3100/fso2], wp=[200/fs02,3200/fs02],
   gpass=0.0, gstop=30.0)

The length of the resulting filter will be dependent upon the depth of the stop bands and the steepness of the response curve which is determined by the difference between the corner frequency and stopband frequency.

You use dependency injection when you exactly know what type of objects you require at this point of time. While in case of factory pattern, you just delegate the process of creating objects to factory as you are unclear of what exact type of objects you require.

when you render a request tou coctext some information: for exampel:

return render(request, 'path to template',{'username' :username , 'email'.email})

you can acces to it on template like this : for variabels :

{% if username %}{{ username }}{% endif %}

for array :

{% if username %}{{ username.1 }}{% endif %}
{% if username %}{{ username.2 }}{% endif %}

you can also name array objects in views.py and ten use it like:

{% if username %}{{ username.first }}{% endif %}

if there is other problem i wish to help you

You can expect that exception is not thrown by creating a rule.

@Rule
public ExpectedException expectedException = ExpectedException.none();

filter_by is used for simple queries on the column names using regular kwargs, like

db.users.filter_by(name='Joe')

The same can be accomplished with filter, not using kwargs, but instead using the '==' equality operator, which has been overloaded on the db.users.name object:

db.users.filter(db.users.name=='Joe')

You can also write more powerful queries using filter, such as expressions like:

db.users.filter(or_(db.users.name=='Ryan', db.users.country=='England'))
