I did a quick solution because I was short of time and it worked ok. Although I think the better option is use an Exception Filter, maybe my solution can help in the case that a simple solution is needed.

I did the following. In the controller method I returned a JsonResult with a property "Success" inside the Data:

    [HttpPut]
    public JsonResult UpdateEmployeeConfig(EmployeConfig employeToSave) 
    {
        if (!ModelState.IsValid)
        {
            return new JsonResult
            {
                Data = new { ErrorMessage = "Model is not valid", Success = false },
                ContentEncoding = System.Text.Encoding.UTF8,
                JsonRequestBehavior = JsonRequestBehavior.DenyGet
            };
        }
        try
        {
            MyDbContext db = new MyDbContext();

            db.Entry(employeToSave).State = EntityState.Modified;
            db.SaveChanges();

            DTO.EmployeConfig user = (DTO.EmployeConfig)Session["EmployeLoggin"];

            if (employeToSave.Id == user.Id)
            {
                user.Company = employeToSave.Company;
                user.Language = employeToSave.Language;
                user.Money = employeToSave.Money;
                user.CostCenter = employeToSave.CostCenter;

                Session["EmployeLoggin"] = user;
            }
        }
        catch (Exception ex) 
        {
            return new JsonResult
            {
                Data = new { ErrorMessage = ex.Message, Success = false },
                ContentEncoding = System.Text.Encoding.UTF8,
                JsonRequestBehavior = JsonRequestBehavior.DenyGet
            };
        }

        return new JsonResult() { Data = new { Success = true }, };
    }

Later in the ajax call I just asked for this property to know if I had an exception:

$.ajax({
    url: 'UpdateEmployeeConfig',
    type: 'PUT',
    data: JSON.stringify(EmployeConfig),
    contentType: "application/json;charset=utf-8",
    success: function (data) {
        if (data.Success) {
            //This is for the example. Please do something prettier for the user, :)
            alert('All was really ok');                                           
        }
        else {
            alert('Oups.. we had errors: ' + data.ErrorMessage);
        }
    },
    error: function (request, status, error) {
       alert('oh, errors here. The call to the server is not working.')
    }
});

Hope this helps. Happy code! :P

The information there is I think partially correct:

That's not true. An URL can use spaces. Nothing defines that a space is replaced with a + sign.

As you noted, an URL can NOT use spaces. The HTTP request would get screwed over. I'm not sure where the + is defined, though %20 is standard.

This is another solution for folks who love recursion.

The idea is simple. Divide up input by half and swap the two halves, continue until it reaches single bit.

Illustrated in the example below.

Ex : If Input is 00101010   ==> Expected output is 01010100

1. Divide the input into 2 halves 
    0010 --- 1010

2. Swap the 2 Halves
    1010     0010

3. Repeat the same for each half.
    10 -- 10 ---  00 -- 10
    10    10      10    00

    1-0 -- 1-0 --- 1-0 -- 0-0
    0 1    0 1     0 1    0 0

Done! Output is 01010100

Here is a recursive function to solve it. (Note I have used unsigned ints, so it can work for inputs up to sizeof(unsigned int)*8 bits.

The recursive function takes 2 parameters - The value whose bits need to be reversed and the number of bits in the value.

int reverse_bits_recursive(unsigned int num, unsigned int numBits)
{
    unsigned int reversedNum;;
    unsigned int mask = 0;

    mask = (0x1 << (numBits/2)) - 1;

    if (numBits == 1) return num;
    reversedNum = reverse_bits_recursive(num >> numBits/2, numBits/2) |
                   reverse_bits_recursive((num & mask), numBits/2) << numBits/2;
    return reversedNum;
}

int main()
{
    unsigned int reversedNum;
    unsigned int num;

    num = 0x55;
    reversedNum = reverse_bits_recursive(num, 8);
    printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);

    num = 0xabcd;
    reversedNum = reverse_bits_recursive(num, 16);
    printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);

    num = 0x123456;
    reversedNum = reverse_bits_recursive(num, 24);
    printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);

    num = 0x11223344;
    reversedNum = reverse_bits_recursive(num,32);
    printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);
}

This is the output:

Bit Reversal Input = 0x55 Output = 0xaa
Bit Reversal Input = 0xabcd Output = 0xb3d5
Bit Reversal Input = 0x123456 Output = 0x651690
Bit Reversal Input = 0x11223344 Output = 0x22cc4488

By entering $PATH on its own at the command prompt, you're trying to run it. This isn't like Windows where you can get your path output by simply typing path.

If you want to see what the path is, simply echo it:

echo $PATH

For my case, it is solved by changing the properties of edmx file.

1. Open the edmx file
2. Right click on any place of the EDMX designer
3. choose properties
4. update Property called "Metadata Artifact Processing" to "Embed in Output Assembly"

this solved the problem for me. The problem is, when the container try to find the meta data, it cant find it. so simply make it in the same assembly. this solution will not work if you have your edmx files in another assembly

It's like whisky and scotch, all web apps are web site, but not all web sites are web app.

A web application or Rich Internet Applications is a web site that does more than displaying content, it has a business logic. It’s intended for user interactions, performing actual business functions. Compared to web sites, i.e. blogs and news sites, web apps provide a richer user experience.

The use case of an application is always to DO something with it

— Christian Heilmann (Principal Developer Evangelist at Mozilla Corporation)

well, I know that I'm a bit too late, but I tried all of your solutions and with no success! So here is how I managed to do it. First of all, I'm working on an Asp.Net MVC project. The Only thing I changed was in my c# method getInvitation:

public ActionResult getInvitation (Guid s_ID)
{
    using (var db = new cRM_Verband_BWEntities())
    {
        var listSidsMit = (from data in db.TERMINEINLADUNGEN where data.RECID_KOMMUNIKATIONEN == s_ID select data.RECID_MITARBEITER.ToString()).ToArray();
        return Json(listSidsMit);
    }
}

SuccessFunction in JS :

function successFunction(result) {
    console.log(result);
}

I changed the Method Type from string[] to ActionResult and of course at the end I wrapped my array listSidsMit with the Json method.

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.

You should try using Type.IsAssignableFrom instead.

Turns out the binding of style to a string doesn't work. The solution would be to bind the background of the style.

 <div class="circle" [style.background]="color">

Use a border-radius property of 50%.

So for example:

.example-div {

    border-radius: 50%

}

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

This is what you are looking for. It has examples for each side you want with a shadow.

.top-box
{
    box-shadow: inset 0 7px 9px -7px rgba(0,0,0,0.4);
}
.left-box
{
    box-shadow: inset 7px 0 9px -7px rgba(0,0,0,0.4);
}
.right-box
{
    box-shadow: inset -7px 0 9px -7px rgba(0,0,0,0.4);
}
.bottom-box
{
    box-shadow: inset 0 -7px 9px -7px rgba(0,0,0,0.4);
}

This answer may appear at the surface to be unrelated, but there is an indirect cause of this error message.

First, the "Uses VFP register..." error message is directly caused from mixing mfloat-abi=soft and mfloat-abi=hard options within your build. This setting must be consistent for all objects that are to be linked. This fact is well covered in the other answers to this question.

The indirect cause of this error may be due to the Eclipse editor getting confused by a self-inflicted error in the project's ".cproject" file. The Eclipse editor frequently reswizzles file links and sometimes it breaks itself when you make changes to your directory structures or file locations. This can also affect the path settings to your gcc compiler - and only for a subset of your project's files. While I'm not yet sure of exactly what causes this failure, replacing the .cproject file with a backup copy corrected this problem for me. In my case I noticed .java.null.pointer errors after adding an include directory path and started receiving the "VFP register error" messages out of the blue. In the build log I noticed that a different path to the gcc compiler was being used for some of my sources that were local to the workspace, but not all of them!? The two gcc compilers were using different float settings for unknown reasons - hence the VFP register error.

I compared the .cproject settings with a older copy and observed differences in entries for the sources causing the trouble - even though the overriding of project settings was disabled. By replacing the .cproject file with the old version the problem went away, and I'm leaving this answer as a reminder of what happened.

There are many ways to get jQuery AJAX response. I am sharing with you two common approaches:

First:

use async=false and within function return ajax-object and later get response ajax-object.responseText

/**
 * jQuery ajax method with async = false, to return response
 * @param  {mix}  selector - your selector
 * @return {mix}           - your ajax response/error
 */
function isSession(selector) {
    return $.ajax({
        type: "POST",
        url: '/order.html',
        data: {
            issession: 1,
            selector: selector
        },
        dataType: "html",
        async: !1,
        error: function() {
            alert("Error occured")
        }
    });
}
// global param
var selector = !0;
// get return ajax object
var ajaxObj = isSession(selector);
// store ajax response in var
var ajaxResponse = ajaxObj.responseText;
// check ajax response
console.log(ajaxResponse);
// your ajax callback function for success
ajaxObj.success(function(response) {
    alert(response);
});

Second:

use $.extend method and make a new function like ajax

/**
 * xResponse function
 *
 * xResponse method is made to return jQuery ajax response
 * 
 * @param  {string} url   [your url or file]
 * @param  {object} your ajax param
 * @return {mix}       [ajax response]
 */
$.extend({
    xResponse: function(url, data) {
        // local var
        var theResponse = null;
        // jQuery ajax
        $.ajax({
            url: url,
            type: 'POST',
            data: data,
            dataType: "html",
            async: false,
            success: function(respText) {
                theResponse = respText;
            }
        });
        // Return the response text
        return theResponse;
    }
});

// set ajax response in var
var xData = $.xResponse('temp.html', {issession: 1,selector: true});

// see response in console
console.log(xData);

you can make it as large as you want...

You should check Connection-specific DNS Suffix when type “ipconfig” or “ifconfig” in terminal

The preprocessor inserts the contents of the files A.h and B.h exactly where the include statement occurs (this is really just copy/paste). When the compiler then parses A.cpp, it finds the declaration of class A before it knows about class B. This causes the error you see. There are two ways to solve this:

1. Include B.h in A.h. It is generally a good idea to include header files in the files where they are needed. If you rely on indirect inclusion though another header, or a special order of includes in the compilation unit (cpp-file), this will only confuse you and others as the project gets bigger.

2. If you use member variable of type B in class A, the compiler needs to know the exact and complete declaration of B, because it needs to create the memory-layout for A. If, on the other hand, you were using a pointer or reference to B, then a forward declaration would suffice, because the memory the compiler needs to reserve for a pointer or reference is independent of the class definition. This would look like this:

   class B; // forward declaration        
   class A {
   public:
       A(int id);
   private:
       int _id;
       B & _b;
   };
   

   This is very useful to avoid circular dependencies among headers.

I hope this helps.

Get the field value through the id and send with ajax

var field = $("#field").val();
$.ajax({
    type: "POST",
    url: "db.php",
    data: {variable_name:field},
    async:false,
    dataType:"json",
    success: function(response) {
       alert(response);
    }
 });

At db.php file get the variable name

$variable_name = $_GET['variable_name'];
mysql_query("SELECT password FROM table_name WHERE password='".md5($variable_name)."'");

I had the same problem on my mac and found it was because the Mac was replacing the standard quotes with curly quotes which are illegal javascript characters.

To fix this I had to change the settings on my mac System Preferences=>Keyboard=>Text(tab) uncheck use smart quotes and dashes (default was checked).

Use something such as the following:

if (String.IsNullOrEmpty(MaterialTextBox.Text)) 

This is not a direct answer to OP's question, this is more of the stuffs (experiments) I tried so far to solve the same problem and obtained some results and have some observations that I want to share, I am curious if we can have some further insights from this.

I just tried my minimax implementation with alpha-beta pruning with search-tree depth cutoff at 3 and 5. I was trying to solve the same problem for a 4x4 grid as a project assignment for the edX course ColumbiaX: CSMM.101x Artificial Intelligence (AI).

I applied convex combination (tried different heuristic weights) of couple of heuristic evaluation functions, mainly from intuition and from the ones discussed above:

1. Monotonicity
2. Free Space Available

In my case, the computer player is completely random, but still i assumed adversarial settings and implemented the AI player agent as the max player.

I have 4x4 grid for playing the game.

Observation:

If I assign too much weights to the first heuristic function or the second heuristic function, both the cases the scores the AI player gets are low. I played with many possible weight assignments to the heuristic functions and take a convex combination, but very rarely the AI player is able to score 2048. Most of the times it either stops at 1024 or 512.

I also tried the corner heuristic, but for some reason it makes the results worse, any intuition why?

Also, I tried to increase the search depth cut-off from 3 to 5 (I can't increase it more since searching that space exceeds allowed time even with pruning) and added one more heuristic that looks at the values of adjacent tiles and gives more points if they are merge-able, but still I am not able to get 2048.

I think it will be better to use Expectimax instead of minimax, but still I want to solve this problem with minimax only and obtain high scores such as 2048 or 4096. I am not sure whether I am missing anything.

Below animation shows the last few steps of the game played by the AI agent with the computer player:

Any insights will be really very helpful, thanks in advance. (This is the link of my blog post for the article: https://sandipanweb.wordpress.com/2017/03/06/using-minimax-with-alpha-beta-pruning-and-heuristic-evaluation-to-solve-2048-game-with-computer/ and the youtube video: https://www.youtube.com/watch?v=VnVFilfZ0r4)

The following animation shows the last few steps of the game played where the AI player agent could get 2048 scores, this time adding the absolute value heuristic too:

The following figures show the game tree explored by the player AI agent assuming the computer as adversary for just a single step:

those various ways of switch ...

# by index
switch(1, "one", "two")
## [1] "one"


# by index with complex expressions
switch(2, {"one"}, {"two"})
## [1] "two"


# by index with complex named expression
switch(1, foo={"one"}, bar={"two"})
## [1] "one"


# by name with complex named expression
switch("bar", foo={"one"}, bar={"two"})
## [1] "two"

It depends.

Start with Basic I/O, take a look at Properties, take a look at Preferences API and maybe even Java API for XML Processing and Java Architecture for XML Binding

And if none of those meet your particular needs, you could even look at using some kind of Database

The return type depends on the server, sometimes the response is indeed a JSON array but sent as text/plain

Setting the accept headers in the request should get the correct type:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

which can then be serialized to a JSON list or array. Thanks for the comment from @svick which made me curious that it should work.

The Exception I got without configuring the accept headers was System.Net.Http.UnsupportedMediaTypeException.

Following code is cleaner and should work (untested, but works in my case):

    var client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    var response = await client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs");
    var model = await response.Content.ReadAsAsync<List<Job>>();

Here you have an example

$("#profiles-thread").select2({
    minimumInputLength: 2,
    tags: [],
    ajax: {
        url: URL,
        dataType: 'json',
        type: "GET",
        quietMillis: 50,
        data: function (term) {
            return {
                term: term
            };
        },
        results: function (data) {
            return {
                results: $.map(data, function (item) {
                    return {
                        text: item.completeName,
                        slug: item.slug,
                        id: item.id
                    }
                })
            };
        }
    }
});

It's quite easy

Simplest - and I changed the checkbox class to ID as well:

$(function() {_x000D_
  $("#coupon_question").on("click",function() {_x000D_
    $(".answer").toggle(this.checked);_x000D_
  });_x000D_
});

.answer { display:none }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<fieldset class="question">_x000D_
  <label for="coupon_question">Do you have a coupon?</label>_x000D_
  <input id="coupon_question" type="checkbox" name="coupon_question" value="1" />_x000D_
  <span class="item-text">Yes</span>_x000D_
</fieldset>_x000D_
_x000D_
<fieldset class="answer">_x000D_

There are already many good answers to the part "what is uintptr_t data type". I will try to address the "what it can be used for?" part in this post.

Primarily for bitwise operations on pointers. Remember that in C++ one cannot perform bitwise operations on pointers. For reasons see Why can't you do bitwise operations on pointer in C, and is there a way around this?

Thus in order to do bitwise operations on pointers one would need to cast pointers to type unitpr_t and then perform bitwise operations.

Here is an example of a function that I just wrote to do bitwise exclusive or of 2 pointers to store in a XOR linked list so that we can traverse in both directions like a doubly linked list but without the penalty of storing 2 pointers in each node.

 template <typename T>
 T* xor_ptrs(T* t1, T* t2)
 {
     return reinterpret_cast<T*>(reinterpret_cast<uintptr_t>(t1)^reinterpret_cast<uintptr_t>(t2));
  }

Install and ensure mysqld us running..

Go into database and setup root user:

sudo mysql -u root
SELECT User,Host FROM mysql.user;
DROP USER 'root'@'localhost';
CREATE USER 'root'@'%' IDENTIFIED BY 'obamathelongleggedmacdaddy';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit;

Edit mysqld permissions and restart:

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

# edit the line to be this:
bind-address=0.0.0.0

sudo systemctl stop mysql
sudo systemctl start mysql

From another machine, test.. Obvs port (3306) on mysqld machine must allow connection from test machine.

mysql -u root -p -h 123.456.789.666

All the additional "security" of MySql doesn't help security at all, it just complicates and obfuscates, it is now actually easier to screw it up than in the old days, where you just used a really long password.

Simply

if(isset($_POST['filename'])){
 $filename = $_POST['filename'];
 echo $filename;
}
else{
 echo "POST filename is not assigned";
}

The DATEDIFF function is use to calculate the number of days between the required date

Example if you are diff current date from given date in string format

SELECT * , DATEDIFF(CURDATE(),STR_TO_DATE('01/11/2017', '%m/%d/%Y')) AS days FROM consignments WHERE code = '1610000154'

Here, STR_TO_DATE () : Take a string and returns a date specified by a format mask;

For your example :

SELECT dtCreated
    , bActive
    , dtLastPaymentAttempt
    , dtLastUpdated
    , dtLastVisit
    , DATEDIFF(dtLastUpdated, dtCreated) as Difference
FROM Customers
WHERE (bActive = 'true') 
    AND (dtLastUpdated > '2012-01-01 00:00:00')

Tested on mysql server 5.7.17

CURRENT_TIMESTAMP is version specific and is now allowed for DATETIME columns as of version 5.6.

If origin points to a bare repository on disk, this error can happen if that directory has been moved (even if you update the working copy's remotes). For example

$ mv /path/to/origin /somewhere/else
$ git remote set-url origin /somewhere/else
$ git diff origin/master
fatal: ambiguous argument 'origin': unknown revision or path not in the working tree.

Pulling once from the new origin solves the problem:

$ git stash
$ git pull origin master
$ git stash pop

This means that you are doing a foreach on something that is not an array.

Check out all your foreach statements, and look if the thing before the as, to make sure it is actually an array. Use var_dump to dump it.

Then fix the one where it isn't an array.

How to reproduce this error:

<?php
$skipper = "abcd";
foreach ($skipper as $item){       //the warning happens on this line.
    print "ok";
}
?>

Make sure $skipper is an array.

JPA manages the version under the hood for you, however it doesn't do so when you update your record via JPAUpdateClause, in such cases you need to manually add the version increment to the query.

Same can be said about updating via JPQL, i.e. not a simple change to the entity, but an update command to the database even if that is done by hibernate

I am implementing old http (0.9, 1.0, 1.1) request and response reader/writer. Request URI is the most problematic place.

You can't just use RFC 1738, 2396 or 3986 as it is. There are many old HTTP clients and servers that allows more characters. So I've made research based on accidentally published webserver access logs: "GET URI HTTP/1.0" 200.

I've found that the following non-standard characters are often used in URI:

\ { } < > | ` ^ "

These characters were described in RFC 1738 as unsafe.

If you want to be compatible with all old HTTP clients and servers - you have to allow these characters in request URI.

Please read more information about this research in oghttp-request-collector.

You can parse the output of ifconfig

string yourWord = "Derp derp";

Console.WriteLine(new string(yourWord.Select(c => char.IsLetter(c) ? '_' : c).ToArray()));

Yields:

First of all, when your first initial window is loaded, it is cached. Therefore, when creating a new window from the first window, the contents of the new window are not loaded from the server, but are loaded from the cache. Consequently, no onload event occurs when you create the new window.

However, in this case, an onpageshow event occurs. It always occurs after the onload event and even when the page is loaded from cache. Plus, it now supported by all major browsers.

 window.popup = window.open($(this).attr('href'), 'Ad', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0');
 $(window.popup).onpageshow = function() {
     alert("Popup has loaded a page");
 };

The w3school website elaborates more on this:

The onpageshow event is similar to the onload event, except that it occurs after the onload event when the page first loads. Also, the onpageshow event occurs every time the page is loaded, whereas the onload event does not occur when the page is loaded from the cache.

when a developer use an initializer block, the Java Compiler copies the initializer into each constructor of the current class.

Example:

the following code:

class MyClass {

    private int myField = 3;
    {
        myField = myField + 2;
        //myField is worth 5 for all instance
    }

    public MyClass() {
        myField = myField * 4;
        //myField is worth 20 for all instance initialized with this construtor
    }

    public MyClass(int _myParam) {
        if (_myParam > 0) {
            myField = myField * 4;
            //myField is worth 20 for all instance initialized with this construtor
            //if _myParam is greater than 0
        } else {
            myField = myField + 5;
            //myField is worth 10 for all instance initialized with this construtor
            //if _myParam is lower than 0 or if _myParam is worth 0
        }
    }

    public void setMyField(int _myField) {
        myField = _myField;
    }


    public int getMyField() {
        return myField;
    }
}

public class MainClass{

    public static void main(String[] args) {
        MyClass myFirstInstance_ = new MyClass();
        System.out.println(myFirstInstance_.getMyField());//20
        MyClass mySecondInstance_ = new MyClass(1);
        System.out.println(mySecondInstance_.getMyField());//20
        MyClass myThirdInstance_ = new MyClass(-1);
        System.out.println(myThirdInstance_.getMyField());//10
    }
}

is equivalent to:

class MyClass {

    private int myField = 3;

    public MyClass() {
        myField = myField + 2;
        myField = myField * 4;
        //myField is worth 20 for all instance initialized with this construtor
    }

    public MyClass(int _myParam) {
        myField = myField + 2;
        if (_myParam > 0) {
            myField = myField * 4;
            //myField is worth 20 for all instance initialized with this construtor
            //if _myParam is greater than 0
        } else {
            myField = myField + 5;
            //myField is worth 10 for all instance initialized with this construtor
            //if _myParam is lower than 0 or if _myParam is worth 0
        }
    }

    public void setMyField(int _myField) {
        myField = _myField;
    }


    public int getMyField() {
        return myField;
    }
}

public class MainClass{

    public static void main(String[] args) {
        MyClass myFirstInstance_ = new MyClass();
        System.out.println(myFirstInstance_.getMyField());//20
        MyClass mySecondInstance_ = new MyClass(1);
        System.out.println(mySecondInstance_.getMyField());//20
        MyClass myThirdInstance_ = new MyClass(-1);
        System.out.println(myThirdInstance_.getMyField());//10
    }
}

I hope my example is understood by developers.

You can send an HTTP request to http://finance.yahoo.com requesting symbols, names, quotes, and all sorts of other data. Data is returned as a .CSV so you can request multiple symbols in one query.

So if you send:

http://finance.yahoo.com/d/quotes.csv?s=MSFT+F+ATT&f=sn

You'll get back something like:

"MSFT","Microsoft Corp"
"F","FORD MOTOR CO"
"ATT","AT&T"

Here is an article called Downloading Yahoo Data which includes the various tags used to request the data.

Use DATE(NOW()) to compare dates

DATE(NOW()) will give you the date part of current date and DATE(duedate) will give you the date part of the due date. then you can easily compare the dates

So you can compare it like

DATE(NOW()) = DATE(duedate)

OR

DATE(duedate) = CURDATE() 

See here

According to the latest pandas documentation you can read a csv file selecting only the columns which you want to read.

import pandas as pd

df = pd.read_csv('some_data.csv', usecols = ['col1','col2'], low_memory = True)

Here we use usecols which reads only selected columns in a dataframe.

We are using low_memory so that we Internally process the file in chunks.

Float to string - String.valueOf()

float amount=100.00f;
String strAmount=String.valueOf(amount);
// or  Float.toString(float)

String to Float - Float.parseFloat()

String strAmount="100.20";
float amount=Float.parseFloat(strAmount)
// or  Float.valueOf(string)

It's only supposed to send the information to the server. The reason that it must preceed the file field is that it has to come before the file payload in the request for the server to be able to use it to check the size of the upload.

How the value is used on the server depends on what you use to take care of the upload. The code is supposedly intended for a specific upload component that specifically looks for that value.

It seems that the built in upload support in PHP is one to use this field value.

Hey my steps to make this work were:

1. ctrl + shift+ p and look for preferences: keyboard shortcuts

or you can use ctrl k + ctrl s to open it directly

2. Look in the search box for Terminal: Focus Terminal, I set up for myself alt + T alt + T but you can select the combination that you want

3. Look in the search box for View: Focus Active Editor Group, set up for myself alt + E alt + E but again you can select the combination that you want

That's it, I hope this help

Postgres Enterprise Manager from EnterpriseDB is probably the most advanced you'll find. It includes all the features of pgAdmin, plus monitoring of your hosts and database servers, predictive reporting, alerting and a SQL Profiler.

1. First you have to run the mongod command in your terminal. Make sure the command executes properly.

2. Then in a new terminal tab run the mongo command.

3. Then open the Robomongo GUI and create a new connection with the default settings.

Your column is nullable

int maxAge = context.Persons.Select(p => p.Age).Max() ?? 0;

Your column is non-nullable

int maxAge = context.Persons.Select(p => p.Age).Cast<int?>().Max() ?? 0;

In both cases, you can use the second code. If you use DefaultIfEmpty, you will do a bigger query on your server. For people who are interested, here are the EF6 equivalent:

Query without DefaultIfEmpty

SELECT 
    [GroupBy1].[A1] AS [C1]
    FROM ( SELECT 
        MAX([Extent1].[Age]) AS [A1]
        FROM [dbo].[Persons] AS [Extent1]
    )  AS [GroupBy1]

Query with DefaultIfEmpty

SELECT 
    [GroupBy1].[A1] AS [C1]
    FROM ( SELECT 
        MAX([Join1].[A1]) AS [A1]
        FROM ( SELECT 
            CASE WHEN ([Project1].[C1] IS NULL) THEN 0 ELSE [Project1].[Age] END AS [A1]
            FROM   ( SELECT 1 AS X ) AS [SingleRowTable1]
            LEFT OUTER JOIN  (SELECT 
                [Extent1].[Age] AS [Age], 
                cast(1 as tinyint) AS [C1]
                FROM [dbo].[Persons] AS [Extent1]) AS [Project1] ON 1 = 1
        )  AS [Join1]
    )  AS [GroupBy1]

        FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpserver));

        reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
        FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();

        Stream responseStream = response.GetResponseStream();

        // use the stream to read file from FTP

I hope it can help you.

As mentioned in other answers, there are multiple ways to generate a table of contents automatically. Most are open source software and can be adapted to your needs.

What I was missing is, however, a visually attractive formatting for a table of contents, using the limited options that Markdown provides. We came up with the following:

Code

## Content

**[1. Markdown](#heading--1)**

  * [1.1. Markdown formatting cheatsheet](#heading--1-1)
  * [1.2. Markdown formatting details](#heading--1-2)

**[2. BBCode formatting](#heading--2)**

  * [2.1. Basic text formatting](#heading--2-1)

      * [2.1.1. Not so basic text formatting](#heading--2-1-1)

  * [2.2. Lists, Images, Code](#heading--2-2)
  * [2.3. Special features](#heading--2-3)

----

Inside your document, you would place the target subpart markers like this:

<div id="heading--1-1"/>
### 1.1. Markdown formatting cheatsheet

Depending on where and how you use Markdown, the following should also work, and provides nicer-looking Markdown code:

### 1.1. Markdown formatting cheatsheet <a name="heading--1-1"/>

Example rendering

Content

1. Markdown

• 1.1. Markdown formatting cheatsheet
• 1.2. Markdown formatting details

2. BBCode formatting

• 2.1. Basic text formatting

  • 2.1.1. Not so basic text formatting

• 2.2. Lists, Images, Code

• 2.3. Special features

---

Advantages

• You can add as many levels of chapters and sub-chapters as you need. In the Table of Contents, these would appear as nested unordered lists on deeper levels.

• No use of ordered lists. These would create an indentation, would not link the number, and cannot be used to create decimal classification numbering like "1.1.".

• No use of lists for the first level. Here, using an unordered list is possible, but not necessary: the indentation and bullet just add visual clutter and no function here, so we don't use a list for the first ToC level at all.

• Visual emphasis on the first-level sections in the table of content by bold print.

• Short, meaningful subpart markers that look "beautiful" in the browser's URL bar such as #heading--1-1 rather than markers containing transformed pieces of the actual heading.

• The code uses H2 headings (## …) for sections, H3 headings (### …) for sub-headings etc.. This makes the source code easier to read because ## … provides a stronger visual clue when scrolling through compared to the case where sections would start with H1 headings (# …). It is still logically consistent as you use the H1 heading for the document title itself.

• Finally, we add a nice horizontal rule to separate the table of contents from the actual content.

For more about this technique and how we use it inside the forum software Discourse, see here.

SQL Server allows you to join tables from different databases as long as those databases are on the same server. The join syntax is the same; the only difference is that you must fully specify table names.

Let's suppose you have two databases on the same server - Db1 and Db2. Db1 has a table called Clients with a column ClientId and Db2 has a table called Messages with a column ClientId (let's leave asside why those tables are in different databases).

Now, to perform a join on the above-mentioned tables you will be using this query:

select *
from Db1.dbo.Clients c
join Db2.dbo.Messages m on c.ClientId = m.ClientId

@tredder solution with editing applicationHost.config is the one that works if you have several different applications located within virtual directories on IIS.

My case is:

• I do have API project and APP project, under the same domain, placed in different virtual directories
• Root page XXX doesn't seem to propagate ASPNETCORE_ENVIRONMENT variable to its children in virtual directories and...
• ...I'm unable to set the variables inside the virtual directory as @NickAb described (got error The request is not supported. (Exception from HRESULT: 0x80070032) during saving changes in Configuration Editor):

• Going into applicationHost.config and manually creating nodes like this:

  <location path="XXX/app"> <system.webServer> <aspNetCore> <environmentVariables> <clear /> <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" /> </environmentVariables> </aspNetCore> </system.webServer> </location> <location path="XXX/api"> <system.webServer> <aspNetCore> <environmentVariables> <clear /> <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" /> </environmentVariables> </aspNetCore> </system.webServer> </location>

and restarting the IIS did the job.

Delete .gitignore file from appname/gen/ to solve this issue.

^{A more complete version of fred's answer:}

Manual way

First you need a tool to extract all the (compiled) classes on the DEX to a JAR.
There's one called dex2jar, which is made by a chinese student.

Then, you can use jd-gui to decompile the classes on the JAR to source code.
The resulting source should be quite readable, as dex2jar applies some optimizations.

Automatic way

You can use APKTool. It will automatically extract all the classes (.dex), resources (.asrc), then it will convert binary XML to human-readable XML, and it will also dissassemble the classes for you.
Disassembly will always be more robust than decompiling, especially with
JARs obfuscated with Pro Guard!

Just tell APKTool to decode the APK into a directory, then modify what you want,
and finally encode it back to an APK. That's all.

Important: APKTool dissassembles. It doesn't decompile.
The generated code won't be Java source.
But you should be able to read it, and even edit it if you're familiar with jasmin.
If you want Java source, please go over the Manual way.

I came across this post while hunting down a solution for myself. By using chrome's inspector, I was able to determine that the striped color was being applied from the --bs-table-striped-color tag.

overriding that tag in your css:

<style scoped>
table {
--bs-table-striped-color: #85d1ee;
}
</style>

Another option is to update the Microsoft.AspnNet.Mvc NuGet package. Be careful, because NuGet update does not update the Web.Config. You should update all previous version numbers to updated number. For example if you update from asp.net MVC 4.0.0.0 to 5.0.0.0, then this should be replaced in the Web.Config:

    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

Let's say we are searching for release/1.0.5

When git fetch -all is not working and that you cannot see the remote branch and git branch -r not show this specific branch.

1. Print all refs from remote (branches, tags, ...):

git ls-remote origin Should show you remote branch you are searching for.

e51c80fc0e03abeb2379327d85ceca3ca7bc3ee5        refs/heads/fix/PROJECT-352
179b545ac9dab49f85cecb5aca0d85cec8fb152d        refs/heads/fix/PROJECT-5
e850a29846ee1ecc9561f7717205c5f2d78a992b        refs/heads/master
ab4539faa42777bf98fb8785cec654f46f858d2a        refs/heads/release/1.0.5
dee135fb65685cec287c99b9d195d92441a60c2d        refs/heads/release/1.0.4
36e385cec9b639560d1d8b093034ed16a402c855        refs/heads/release/1.0
d80c1a52012985cec2f191a660341d8b7dd91deb        refs/tags/v1.0

The new branch 'release/1.0.5' appears in the output.

2. Force fetching a remote branch:

git fetch origin <name_branch>:<name_branch>

$ git fetch origin release/1.0.5:release/1.0.5

remote: Enumerating objects: 385, done.
remote: Counting objects: 100% (313/313), done.
remote: Compressing objects: 100% (160/160), done.

Receiving objects: 100% (231/231), 21.02 KiB | 1.05 MiB/s, done.
Resolving deltas: 100% (98/98), completed with 42 local objects.
From http://git.repo:8080/projects/projectX
 * [new branch]        release/1.0.5 -> release/1.0.5

Now you have also the refs locally, you checkout (or whatever) this branch.

Job done!

If this is what you want ...simply add button inside the Fragment.

    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.LocationChooser">


    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right|top"
        android:text="Demo Button" 
        android:padding="10dp"
        android:layout_marginTop="20dp"
        android:paddingRight="10dp"/>

</fragment>

Why not just do it like this:

Select Case parameter     
   Case "userID"                
      ' does something here.        
   Case "packageID"                
      ' does something here.        
   Case "mvrType"                 
      If otherFactor Then                         
         ' does something here.                 
      Else                         
         ' do processing originally part of GoTo here
         Exit Select  
      End If      
End Select

I'm not sure if not having a case else at the end is a big deal or not, but it seems like you don't really need the go to if you just put it in the else statement of your if.

also had same problem once,

if you are unable to solve the problem you can run the following command on command line
chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security

Note: you have to navigate to the installation path of your chrome.
For example:cd C:\Program Files\Google\Chrome\Application

A developer session chrome browser will be opened, you can now launch your app on the new chrome browse.
I hope this should be helpful

Try this...

SELECT
    AlarmEventTransactionTableTable.TxnID,
    CASE
        WHEN DeviceID IN('7', '10', '62', '58', '60',

                 '142', '143', '164') THEN '01'
        WHEN DeviceID IN('8', '9', '63', '59', '61',
                 '47', '49', '51', '138', '140',

        ELSE 'NA' END AS clocking,
    AlarmEventTransactionTable.DateTimeOfTxn

Just remove highlighted string

SELECT AlarmEventTransactionTableTable.TxnID, CASE AlarmEventTransactions.DeviceID WHEN DeviceID IN('7', '10', '62', '58', '60', ...)

This may be the easiest method

• Right click on the project and select "Add Service Reference..."
• In the Address: box, enter the physical path (C:\test\project....) of the downloaded/Modified wsdl.
• Hit Go

The answer is right in the MYSQL manual itself.

"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"

In the scenario where the widget size needs to be set programmatically, ensure the below rules.

1. Set LayoutParam for the Layout in which you are adding that view. In my case I am adding to TableRow so I had to do TableRow.LayoutParams
2. Follow this code

final float scale = getResources().getDisplayMetrics().density; int dpWidthInPx = (int) (17 * scale); int dpHeightInPx = (int) (17 * scale);

TableRow.LayoutParams deletelayoutParams = new TableRow.LayoutParams(dpWidthInPx, dpHeightInPx); button.setLayoutParams(deletelayoutParams); tableRow.addView(button, 1);

I use a mixture of float and overflow-x:hidden. Minimal code, always works.

https://jsfiddle.net/9934sc4d/4/ - PLUS you don't need to clear your float!

.left-half{
    width:200px;
    float:left;
}
.right-half{
    overflow-x:hidden;
}

How to check if a list is empty in Python?

It generalizes to more than just lists:

>>> a = ""
>>> not a
True

>>> a = []
>>> not a
True

>>> a = 0
>>> not a
True

>>> a = 0.0
>>> not a
True

>>> a = numpy.array([])
>>> not a
True

Notably, it will not work for "0" as a string because the string does in fact contain something - a character containing "0". For that you have to convert it to an int:

>>> a = "0"
>>> not a
False

>>> a = '0'
>>> not int(a)
True

<div id="image">Example to have Background Image</div>

We need to Add the below content in Style tag:

.image {
  background-image: url('C:\Users\ajai\Desktop\10.jpg');
}

As the message error says, you need to Increase the length of your column to fit the length of the data you are trying to insert (0000-00-00)

EDIT 1:

Following your comment, I run a test table:

mysql> create table testDate(id int(2) not null auto_increment, pdd date default null, primary key(id));
Query OK, 0 rows affected (0.20 sec)

Insertion:

mysql> insert into testDate values(1,'0000-00-00');
Query OK, 1 row affected (0.06 sec)

EDIT 2:

So, aparently you want to insert a NULL value to pdd field as your comment states ? You can do that in 2 ways like this:

Method 1:

mysql> insert into testDate values(2,'');
Query OK, 1 row affected, 1 warning (0.06 sec)

Method 2:

mysql> insert into testDate values(3,NULL);
Query OK, 1 row affected (0.07 sec)

EDIT 3:

You failed to change the default value of pdd field. Here is the syntax how to do it (in my case, I set it to NULL in the start, now I will change it to NOT NULL)

mysql> alter table testDate modify pdd date not null;
Query OK, 3 rows affected, 1 warning (0.60 sec)
Records: 3  Duplicates: 0  Warnings: 1

URLs should be case insensitive unless there is a good reason why they are should not be.

This is not mandatory (it is not any part of an RFC) but it makes the communication and storage of URLs far more reliable.

If I have two pages on a website:

http://stackoverflow.com/ABOUT.html

and

http://stackoverflow.com/about.html

How should they differ? Maybe one is written 'shouting style' (caps) - but from an IA point of view, the distinction should never be made by a change in the case of the URL.

Moreover, it is easy to implement this in Apache - just use CheckSpelling On from mod_Speling.

// Select and loop the container element of the elements you want to equalise
        $('.equal').each(function(){  

          // Cache the highest
          var highestBox = 0;

          // Select and loop the elements you want to equalise
          $('.col-lg-4', this).each(function(){

            // If this box is higher than the cached highest then store it
            if($(this).height() > highestBox) {
              highestBox = $(this).height(); 
            }

          });  

          // Set the height of all those children to whichever was highest 
          $('.col-lg-4',this).height(highestBox);

        }); 

    });

I managed with a simple $(...).click(); with JQuery 1.6.1

The application automatically stops when the last Stage is closed. At this moment, the stop() method of your Application class is called, so you don't need an equivalent to setDefaultCloseOperation()

If you want to stop the application before that, you can call Platform.exit(), for example in your onCloseRequest call.

You can have all these information on the javadoc page of Application : http://docs.oracle.com/javafx/2/api/javafx/application/Application.html

Implementing the TimeZone class to set the timezone to the Calendar takes care of the daylight savings.

java.util.TimeZone represents a time zone offset, and also figures out daylight savings.

sample code:

TimeZone est_timeZone = TimeZoneIDProvider.getTimeZoneID(TimeZoneID.US_EASTERN).getTimeZone();
Calendar enteredCalendar = Calendar.getInstance();
enteredCalendar.setTimeZone(est_timeZone);

I know this question is 5 years old, but for anybody wondering how to do this without re-rendering the main page. This solution uses the dart editor/scripting language.

You could have an <object> tag that contains a data attribute. Make the <object> 1px by 1px and then use something like dart to dynamically change the <object>'s data attribute which re-renders the data in the 1px by 1px object.

HTML Script:

<object id="external_source" type="text/html" data="" width="1px" height="1px">
</object>

<button id="button1" type="button">Start Script</button>

<script async type="application/dart" src="dartScript.dart"></script>
<script async src="packages/browser/dart.js"></script>

someScript.php:

<?php
echo 'hello world';
?>

dartScript.dart:

import 'dart:html';

InputElement button1;
ObjectElement externalSource;

void main() {
    button1 = querySelector('#button1')
        ..onClick.listen(runExternalSource);

    externalSource = querySelector('#external_source');
}

void runExternalSource(Event e) {
    externalSource.setAttribute('data', 'someScript.php');
}

So long as you aren't posting any information and you are just looking to run a script, this should work just fine.

Just build the dart script using "pub Build(generate JS)" and then upload the package onto your server.

Binary semaphore and Mutex are different. From OS perspective, a binary semaphore and counting semaphore are implemented in the same way and a binary semaphore can have a value 0 or 1.

Mutex -> Can only be used for one and only purpose of mutual exclusion for a critical section of code.

Semaphore -> Can be used to solve variety of problems. A binary semaphore can be used for signalling and also solve mutual exclusion problem. When initialized to 0, it solves signalling problem and when initialized to 1, it solves mutual exclusion problem.

When the number of resources are more and needs to be synchronized, we can use counting semaphore.

In my blog, I have discussed these topics in detail.

For my case I was getting that error when I was using async function on my server-side to fetch documents using mongoose. It turned out that the reason was I forgot to put await before calling find({}) method. Adding that part fixed my issue.

3 easy steps to run your PHP program is:

1. The easiest way is to install MAMP!

2. Do a 2-minute setup of MAMP.

3. Open the localhost server in your browser at the created port to see your program up and runing!

You could try something like this:

$('input[type="checkbox"]').change(function(){
       var checkedValue = $('input:checkbox:checked').map(function(){
                return this.value;
            }).get();         
            alert(checkedValue);   //display selected checkbox value     
 })

Here

$('input[type="checkbox"]').change(function() call when any checkbox checked or unchecked, after this
$('input:checkbox:checked').map(function()  looping on all checkbox,

This works.

<html>
<head>
<script type = "text/javascript">
function write_below(form)
{
var input = document.forms.write.input_to_write.value;
document.getElementById('write_here').innerHTML="Your input was:"+input;
return false;
}
</script>
</head>

<!--Insert more code here-->
<body>
<form name='write' onsubmit='return write_below(this);'>
<input type = "text" name='input_to_write'>
<input type = "button" value = "submit" />
</form>
<div id='write_here'></div></body>
</html>

Returning false from the function never posts it to other page,but does edit the html content.

Use compareWith, A function to compare the option values with the selected values. see here: https://material.angular.io/components/select/api#MatSelect

For an object of the following structure:

listOfObjs = [{ name: 'john', id: '1'}, { name: 'jimmy', id: '2'},...]

Define markup like this:

<mat-form-field>
  <mat-select
    [compareWith]="compareObjects"
    [(ngModel)]="obj">
       <mat-option  *ngFor="let obj of listOfObjs" [value]="obj">
          {{ obj.name }}
       </mat-option>
    </mat-select>
</mat-form-field>

And define comparison function like this:

compareObjects(o1: any, o2: any): boolean {
  return o1.name === o2.name && o1.id === o2.id;
}

There are a couple of important things to know about bash's [[ ]] construction. The first:

Word splitting and pathname expansion are not performed on the words between the [[ and ]]; tilde expansion, parameter and variable expansion, arithmetic expansion, command substitution, process substitution, and quote removal are performed.

The second thing:

An additional binary operator, ‘=~’, is available,... the string to the right of the operator is considered an extended regular expression and matched accordingly... Any part of the pattern may be quoted to force it to be matched as a string.

Consequently, $v on either side of the =~ will be expanded to the value of that variable, but the result will not be word-split or pathname-expanded. In other words, it's perfectly safe to leave variable expansions unquoted on the left-hand side, but you need to know that variable expansions will happen on the right-hand side.

So if you write: [[ $x =~ [$0-9a-zA-Z] ]], the $0 inside the regex on the right will be expanded before the regex is interpreted, which will probably cause the regex to fail to compile (unless the expansion of $0 ends with a digit or punctuation symbol whose ascii value is less than a digit). If you quote the right-hand side like-so [[ $x =~ "[$0-9a-zA-Z]" ]], then the right-hand side will be treated as an ordinary string, not a regex (and $0 will still be expanded). What you really want in this case is [[ $x =~ [\$0-9a-zA-Z] ]]

Similarly, the expression between the [[ and ]] is split into words before the regex is interpreted. So spaces in the regex need to be escaped or quoted. If you wanted to match letters, digits or spaces you could use: [[ $x =~ [0-9a-zA-Z\ ] ]]. Other characters similarly need to be escaped, like #, which would start a comment if not quoted. Of course, you can put the pattern into a variable:

pat="[0-9a-zA-Z ]"
if [[ $x =~ $pat ]]; then ...

For regexes which contain lots of characters which would need to be escaped or quoted to pass through bash's lexer, many people prefer this style. But beware: In this case, you cannot quote the variable expansion:

# This doesn't work:
if [[ $x =~ "$pat" ]]; then ...

Finally, I think what you are trying to do is to verify that the variable only contains valid characters. The easiest way to do this check is to make sure that it does not contain an invalid character. In other words, an expression like this:

valid='0-9a-zA-Z $%&#' # add almost whatever else you want to allow to the list
if [[ ! $x =~ [^$valid] ]]; then ...

! negates the test, turning it into a "does not match" operator, and a [^...] regex character class means "any character other than ...".

The combination of parameter expansion and regex operators can make bash regular expression syntax "almost readable", but there are still some gotchas. (Aren't there always?) One is that you could not put ] into $valid, even if $valid were quoted, except at the very beginning. (That's a Posix regex rule: if you want to include ] in a character class, it needs to go at the beginning. - can go at the beginning or the end, so if you need both ] and -, you need to start with ] and end with -, leading to the regex "I know what I'm doing" emoticon: [][-])

You can also apply multiple transforms using an extra layer of markup e.g.:

<h3 class="rotated-heading">
    <span class="scaled-up">Hey!</span>
</h3>
<style type="text/css">
.rotated-heading
{
    transform: rotate(10deg);
}

.scaled-up
{
    transform: scale(1.5);
}
</style>

This can be really useful when animating elements with transforms using Javascript.

 string input = "0.55";
    var regex1 = new System.Text.RegularExpressions.Regex("(?<=[\\.])[0-9]+");
    if (regex1.IsMatch(input))
    {
        string dp= regex1.Match(input ).Value;
    }

If I've understood your question correctly, then you are looking for the mouseup event, rather than the click event:

$("#message_link").mouseup(function() {
    //Do stuff here
});

The mouseup event fires when the mouse button is released, and does not take into account whether the mouse button was pressed on that element, whereas click takes into account both mousedown and mouseup.

However, click should work fine, because it won't actually fire until the mouse button is released.

An alternative to the answer provided by @Marc

SELECT SUBSTRING(LEFT(YOUR_FIELD, CHARINDEX('[', YOUR_FIELD) - 1), CHARINDEX(';', YOUR_FIELD) + 1, 100)
FROM YOUR_TABLE
WHERE CHARINDEX('[', YOUR_FIELD) > 0 AND
    CHARINDEX(';', YOUR_FIELD) > 0;

This makes sure the delimiters exist, and solves an issue with the currently accepted answer where doing the LEFT last is working with the position of the last delimiter in the original string, rather than the revised substring.

If your base query is expected to return only one row, then you could use this trick:

select NVL( MIN(rate), 0 ) AS rate 
from d_payment_index
where fy = 2007
  and payment_year = 2008
  and program_id = 18

(Oracle code, not sure if NVL is the right function for SQL Server.)

You can create the virtual host first, and then you can specify your path in DocumentRoot

Example: /var/www/html/YOUR_LARAVEL_DIRECTORY_PATH/public

Change

$data[$parts[0]] = $parts[1];

to

if ( ! isset($parts[1])) {
   $parts[1] = null;
}

$data[$parts[0]] = $parts[1];

or simply:

$data[$parts[0]] = isset($parts[1]) ? $parts[1] : null;

Not every line of your file has a colon in it and therefore explode on it returns an array of size 1.

According to php.net possible return values from explode:

Returns an array of strings created by splitting the string parameter on boundaries formed by the delimiter.

If delimiter is an empty string (""), explode() will return FALSE. If delimiter contains a value that is not contained in string and a negative limit is used, then an empty array will be returned, otherwise an array containing string will be returned.

Edit: After Docker 1.9, the docker network command (see below https://stackoverflow.com/a/35184695/977939) is the recommended way to achieve this.

My solution is to set up a dnsmasq on the host to have DNS record automatically updated: "A" records have the names of containers and point to the IP addresses of the containers automatically (every 10 sec). The automatic updating script is pasted here:

#!/bin/bash

# 10 seconds interval time by default
INTERVAL=${INTERVAL:-10}

# dnsmasq config directory
DNSMASQ_CONFIG=${DNSMASQ_CONFIG:-.}

# commands used in this script
DOCKER=${DOCKER:-docker}
SLEEP=${SLEEP:-sleep}
TAIL=${TAIL:-tail}

declare -A service_map

while true
do
    changed=false
    while read line
    do
        name=${line##* }
        ip=$(${DOCKER} inspect --format '{{.NetworkSettings.IPAddress}}' $name)
        if [ -z ${service_map[$name]} ] || [ ${service_map[$name]} != $ip ] # IP addr changed
        then
            service_map[$name]=$ip
            # write to file
            echo $name has a new IP Address $ip >&2
            echo "host-record=$name,$ip"  > "${DNSMASQ_CONFIG}/docker-$name"
            changed=true
        fi
    done < <(${DOCKER} ps | ${TAIL} -n +2)

    # a change of IP address occured, restart dnsmasq
    if [ $changed = true ]
    then
        systemctl restart dnsmasq
    fi

    ${SLEEP} $INTERVAL
done

Make sure your dnsmasq service is available on docker0. Then, start your container with --dns HOST_ADDRESS to use this mini dns service.

Reference: http://docs.blowb.org/setup-host/dnsmasq.html

As a partial answer: mysql -N -B -e "select people, places from things"

-N tells it not to print column headers. -B is "batch mode", and uses tabs to separate fields.

If tab separated values won't suffice, see this Stackoverflow Q&A.

Use toString() when you want to present information to a user (including a developer looking at a log). Never rely in your code on toString() giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString() return, then it was already broken.

If you need to get the exact name used to declare the enum constant, you should use name() as toString may have been overridden.

Here is the entire script with an AJAX call to target a single list within a page with multiple lists. None of the other stuff above worked for me until I used the "id" attribute even though my attribute name is "ItemKey". By using the debugger

Chrome Debug

I was able to see that the selected option had attributes: with a map to the JQuery "id" and the value.

<html>
<head>
<script type="text/JavaScript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
</head>
<body>
<select id="List1"></select>
<select id="List2">
<option id="40000">List item #1</option>
<option id="27888">List item #2</option>
</select>

<div></div>
</body>
<script type="text/JavaScript">
//get a reference to the select element
$select = $('#List1');

//request the JSON data and parse into the select element
$.ajax({
url: 'list.json',
dataType:'JSON',
success:function(data){

//clear the current content of the select
$select.html('');

//iterate over the data and append a select option
$.each(data.List, function(key, val){
$select.append('<option id="' + val.ItemKey + '">' + val.ItemText + '</option>');
})
},

error:function(){

//if there is an error append a 'none available' option
$select.html('<option id="-1">none available</option>');
}
});

$( "#List1" ).change(function () {
var optionSelected = $('#List1 option:selected').attr('id');
$( "div" ).text( optionSelected );
});
</script>
</html>

Here is the JSON File to create...

{  
"List":[  
{  
"Sort":1,
"parentID":0,
"ItemKey":100,
"ItemText":"ListItem-#1"
},
{  
"Sort":2,

"ItemText":"ListItem-#3"
},
{  
"Sort":4,
"parentID":0,

"ItemText":"ListItem-#4"
}
]
}

Hope this helps, thank you all above for getting me this far.

It is because * is used as a metacharacter to signify one or more occurences of previous character. So if i write M* then it will look for files MMMMMM..... ! Here you are using * as the only character so the compiler is looking for the character to find multiple occurences of,so it throws the exception.:)

Very old question but providing some additional information which may help someone else. I also encountered same error and I was using ojdbc14.jar with 12.1.0.2 Oracle Database. On Oracle official web page this information is listed that which version supports which database drivers. Here is the link and it appears that with Oracle 12c and Java 7 or 8 the correct version is ojdbc7.jar.

In the ojdbc6.jar is for 11.2.0.4.

Made it work successfully using the 2 methods: Stephan202's encapsulation and multiple event listeners. I have 3 search tabs, let's define their input text id's in an Array:

var ids = new Array("searchtab1", "searchtab2", "searchtab3");

When the content of searchtab1 changes, I want to update searchtab2 and searchtab3. Did it this way for encapsulation:

for (var i in ids) {
    $("#" + ids[i]).change(function() {
        for (var j in ids) {
            if (this != ids[j]) {
                $("#" + ids[j]).val($(this).val());
            }
        }
    });
}

Multiple event listeners:

for (var i in ids) {
    for (var j in ids) {
        if (ids[i] != ids[j]) {
            $("#" + ids[i]).change(function() {
                $("#" + ids[j]).val($(this).val());
            });
        }
    }
}

I like both methods, but the programmer chose encapsulation, however multiple event listeners worked also. We used Chrome to test it.

One other significant point if you're using C# 6:

'=>' can be used instead of 'get' and is only for 'get only' methods - it can't be used with a 'set'.

For C# 7, see the comment from @avenmore below - it can now be used in more places. Here's a good reference - https://csharp.christiannagel.com/2017/01/25/expressionbodiedmembers/

Since iOS 8, you can't, it doesn't work because Apple changed internal implementation of UIActionSheet. Please refer to Apple Documentation:

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

Let's polyfill:

if(!AbortController){
  class AbortController {
    constructor() {
      this.aborted = false;
      this.signal = this.signal.bind(this);
    }
    signal(abortFn, scope) {
      if (this.aborted) {
        abortFn.apply(scope, { name: 'AbortError' });
        this.aborted = false;
      } else {
        this.abortFn = abortFn.bind(scope);
      }
    }
    abort() {
      if (this.abortFn) {
        this.abortFn({ reason: 'canceled' });
        this.aborted = false;
      } else {
        this.aborted = true;
      }
    }
  }

  const originalFetch = window.fetch;

  const customFetch = (url, options) => {
    const { signal } = options || {};

    return new Promise((resolve, reject) => {
      if (signal) {
        signal(reject, this);
      }
      originalFetch(url, options)
        .then(resolve)
        .catch(reject);
    });
  };

  window.fetch = customFetch;
}

Please have in mind that the code is not tested! Let me know if you have tested it and something didn't work. It may give you warnings that you try to overwrite the 'fetch' function from the JavaScript official library.

Try it:

<input type="button" value="Dont show this again! " onClick="fbLikeDump();WriteCookie();" />

Or also

<script>
function clickEvent(){
    fbLikeDump();
    WriteCookie();
}
</script>
<input type="button" value="Dont show this again! " onClick="clickEvent();" />

@P-A's solution partially works for me. Detail my findings below:

1) The first code snippet is incorrect, see below:

<activity
    ...
    <intent-filter>
        ==> <action android:name="android.intent.action.MAIN" /> <== This line shouldn't be deleted, otherwise will have compile error
        <category android:name="android.intent.category.LAUNCHER" /> //DELETE THIS LINE
    </intent-filter>
</activity>

2) Should use following code to disable all icons before enabling another one, otherwise it will add a new icon, instead of replacing it.

getPackageManager().setComponentEnabledSetting(
        getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

BUT, if you use code above, then shortcut on homescreen will be removed! And it won't be automatically added back. You might be able to programmatically add icon back, but it probably won't stay in the same position as before.

3) Note that the icon won't get changed immediately, it might take several seconds. If you click it right after changing, you might get an error saying: "App isn't installed".

So, IMHO this solution is only suitable for changing icon in app launcher only, not for shortcuts (i.e. the icon on homescreen)

To select an option, use .val('value-of-the-option') on the select element. To trigger the change element, use .change() or .trigger('change').

The problems in your code are the comma instead of the dot in $('.check'),trigger('change'); and the fact that you call it before binding the event handler.

This is what I use.

 public class TimeStamp
    {
        public Int32 UnixTimeStampUTC()
        {
            Int32 unixTimeStamp;
            DateTime currentTime = DateTime.Now;
            DateTime zuluTime = currentTime.ToUniversalTime();
            DateTime unixEpoch = new DateTime(1970, 1, 1);
            unixTimeStamp = (Int32)(zuluTime.Subtract(unixEpoch)).TotalSeconds;
            return unixTimeStamp;
        }
}

Just use

$location.url();

Instead of

$location.path();

You can add flex-direction:column to flex-container

.flex-container {
  flex-direction: column;
}

Add display:inline-block to flex-item

.flex-item {
 display: inline-block;
}

because you added width and height has no effect on this element since it has a display of inline. Try adding display:inline-block or display:block. Learn more about width and height.

Also add to row class( you are given row{} not taken as style)

.row{
  width:100%;
  margin:0 auto;
  text-align:center;
}

Working Demo in Row :

.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  display: flex;
  align-items: center;
  justify-content:center;
  flex-direction:column;
}
.row{
  width:100%;
  margin:0 auto;
  text-align:center;
}
.flex-item {
  background: tomato;
  padding: 5px;
  width: 200px;
  height: 150px;
  margin: 10px;
  line-height: 150px;
  color: white;
  font-weight: bold;
  font-size: 3em;
  text-align: center;
  display: inline-block;

the default text size of the textview

if you not used any of the below

TextAppearance.Small

TextAppearance.Medium

TextAppearance.Large

then the default size is 14sp

The second method creates the instance on the stack, along with such things as something declared int and the list of parameters that are passed into the function.

The first method makes room for a pointer on the stack, which you've set to the location in memory where a new MyClass has been allocated on the heap - or free store.

The first method also requires that you delete what you create with new, whereas in the second method, the class is automatically destructed and freed when it falls out of scope (the next closing brace, usually).

You can try using the a backslash followed by a "u" and then the unicode value for the character, for example the unicode value of the double quote is

" -> U+0022

Therefore if you were setting it as part of text in XML in android it would look something like this,

<TextView
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:text=" \u0022 Showing double quotes \u0022 "/>

This would produce a text in the TextView roughly something like this

" Showing double quotes "

You can find unicode of most symbols and characters here www.unicode-table.com/en

There is a useful guide to the various methods of merging, joining and concatenating online.

For example, as you have no clashing columns you can merge and use the indices as they have the same number of rows:

In [6]:

df_a.merge(df_b, left_index=True, right_index=True)
Out[6]:
        AAseq Biorep  Techrep Treatment     mz      AAseq1 Biorep1  Techrep1  \

From Docker documentation:

docker export does not export the contents of volumes associated with the container. If a volume is mounted on top of an existing directory in the container, docker export will export the contents of the underlying directory, not the contents of the volume. Refer to Backup, restore, or migrate data volumes in the user guide for examples on exporting data in a volume.

:: is basically a namespace resolution operator. It allows you to access items in modules, or class-level items in classes. For example, say you had this setup:

module SomeModule
    module InnerModule
        class MyClass
            CONSTANT = 4
        end
    end
end

You could access CONSTANT from outside the module as SomeModule::InnerModule::MyClass::CONSTANT.

It doesn't affect instance methods defined on a class, since you access those with a different syntax (the dot .).

Relevant note: If you want to go back to the top-level namespace, do this: ::SomeModule – Benjamin Oakes

When calling super() to resolve to a parent's version of a classmethod, instance method, or staticmethod, we want to pass the current class whose scope we are in as the first argument, to indicate which parent's scope we're trying to resolve to, and as a second argument the object of interest to indicate which object we're trying to apply that scope to.

Consider a class hierarchy A, B, and C where each class is the parent of the one following it, and a, b, and c respective instances of each.

super(B, b) 
# resolves to the scope of B's parent i.e. A 
# and applies that scope to b, as if b was an instance of A

super(C, c) 
# resolves to the scope of C's parent i.e. B
# and applies that scope to c

super(B, c) 
# resolves to the scope of B's parent i.e. A 
# and applies that scope to c

Using super with a staticmethod

e.g. using super() from within the __new__() method

class A(object):
    def __new__(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        return super(A, cls).__new__(cls, *a, **kw)

Explanation:

1- even though it's usual for __new__() to take as its first param a reference to the calling class, it is not implemented in Python as a classmethod, but rather a staticmethod. That is, a reference to a class has to be passed explicitly as the first argument when calling __new__() directly:

# if you defined this
class A(object):
    def __new__(cls):
        pass

# calling this would raise a TypeError due to the missing argument
A.__new__()

# whereas this would be fine
A.__new__(A)

2- when calling super() to get to the parent class we pass the child class A as its first argument, then we pass a reference to the object of interest, in this case it's the class reference that was passed when A.__new__(cls) was called. In most cases it also happens to be a reference to the child class. In some situations it might not be, for instance in the case of multiple generation inheritances.

super(A, cls)

3- since as a general rule __new__() is a staticmethod, super(A, cls).__new__ will also return a staticmethod and needs to be supplied all arguments explicitly, including the reference to the object of insterest, in this case cls.

super(A, cls).__new__(cls, *a, **kw)

4- doing the same thing without super

class A(object):
    def __new__(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        return object.__new__(cls, *a, **kw)

Using super with an instance method

e.g. using super() from within __init__()

class A(object): 
    def __init__(self, *a, **kw):
        # ...
        # you make some changes here
        # ...

        super(A, self).__init__(*a, **kw)

Explanation:

1- __init__ is an instance method, meaning that it takes as its first argument a reference to an instance. When called directly from the instance, the reference is passed implicitly, that is you don't need to specify it:

# you try calling `__init__()` from the class without specifying an instance
# and a TypeError is raised due to the expected but missing reference
A.__init__() # TypeError ...

# you create an instance
a = A()

# you call `__init__()` from that instance and it works
a.__init__()

# you can also call `__init__()` with the class and explicitly pass the instance 
A.__init__(a)

2- when calling super() within __init__() we pass the child class as the first argument and the object of interest as a second argument, which in general is a reference to an instance of the child class.

super(A, self)

3- The call super(A, self) returns a proxy that will resolve the scope and apply it to self as if it's now an instance of the parent class. Let's call that proxy s. Since __init__() is an instance method the call s.__init__(...) will implicitly pass a reference of self as the first argument to the parent's __init__().

4- to do the same without super we need to pass a reference to an instance explicitly to the parent's version of __init__().

class A(object): 
    def __init__(self, *a, **kw):
        # ...
        # you make some changes here
        # ...

        object.__init__(self, *a, **kw)

Using super with a classmethod

class A(object):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        print "A.alternate_constructor called"
        return cls(*a, **kw)

class B(A):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        print "B.alternate_constructor called"
        return super(B, cls).alternate_constructor(*a, **kw)

Explanation:

1- A classmethod can be called from the class directly and takes as its first parameter a reference to the class.

# calling directly from the class is fine,
# a reference to the class is passed implicitly
a = A.alternate_constructor()
b = B.alternate_constructor()

2- when calling super() within a classmethod to resolve to its parent's version of it, we want to pass the current child class as the first argument to indicate which parent's scope we're trying to resolve to, and the object of interest as the second argument to indicate which object we want to apply that scope to, which in general is a reference to the child class itself or one of its subclasses.

super(B, cls_or_subcls)

3- The call super(B, cls) resolves to the scope of A and applies it to cls. Since alternate_constructor() is a classmethod the call super(B, cls).alternate_constructor(...) will implicitly pass a reference of cls as the first argument to A's version of alternate_constructor()

super(B, cls).alternate_constructor()

4- to do the same without using super() you would need to get a reference to the unbound version of A.alternate_constructor() (i.e. the explicit version of the function). Simply doing this would not work:

class B(A):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        print "B.alternate_constructor called"
        return A.alternate_constructor(cls, *a, **kw)

The above would not work because the A.alternate_constructor() method takes an implicit reference to A as its first argument. The cls being passed here would be its second argument.

class B(A):
    @classmethod
    def alternate_constructor(cls, *a, **kw):
        # ...
        # whatever you want to specialize or override here
        # ...

        print "B.alternate_constructor called"
        # first we get a reference to the unbound 
        # `A.alternate_constructor` function 
        unbound_func = A.alternate_constructor.im_func
        # now we call it and pass our own `cls` as its first argument
        return unbound_func(cls, *a, **kw)

I would suggest sticking to option 2 (I'm always using it for queries any more complex than SELECT * FROM table) and if you want to print it in a nice way you may always use a separate module.

I know this question is a couple years old, but I am surprised to find that no one suggested:

   text-align: center;

this is a more universal property than justify-content, and is definitely not unique to grid, but I find that when dealing with text, which is what this question specifically asks about, that it aligns text to the center with-out affecting the space between grid items, or the vertical centering. It centers text horizontally where its stands on its vertical axis. I also find it to remove a layer of complexity that justify-content and align-items adds. justify-content and align-items affects the entire grid item or items, text-align centers the text without affecting the container it is in. Hope this helps.

How about

List<object> collection = new List<object>((IEnumerable)myObject);

In case you decide to use dangerous code that is subject to breakage, this extension function will fetch a key from a Dictionary<K,V> according to its internal indexing (which for Mono and .NET currently appears to be in the same order as you get by enumerating the Keys property).

It is much preferable to use Linq: dict.Keys.ElementAt(i), but that function will iterate O(N); the following is O(1) but with a reflection performance penalty.

using System;
using System.Collections.Generic;
using System.Reflection;

public static class Extensions
{
    public static TKey KeyByIndex<TKey,TValue>(this Dictionary<TKey, TValue> dict, int idx)
    {
        Type type = typeof(Dictionary<TKey, TValue>);
        FieldInfo info = type.GetField("entries", BindingFlags.NonPublic | BindingFlags.Instance);
        if (info != null)
        {
            // .NET
            Object element = ((Array)info.GetValue(dict)).GetValue(idx);
            return (TKey)element.GetType().GetField("key", BindingFlags.Public | BindingFlags.Instance).GetValue(element);
        }
        // Mono:
        info = type.GetField("keySlots", BindingFlags.NonPublic | BindingFlags.Instance);
        return (TKey)((Array)info.GetValue(dict)).GetValue(idx);
    }
};

For me, on Ubuntu, the various versions of JDK were in /usr/lib/jvm.

Here is code with AWK. It can be done more simply. But I am not good in AWK.

filename$ ls
abc.a.txt  a.b.c.txt  pp-kk.txt
filename$ find . -type f | awk -F/ '{print $2}' | rev | awk -F"." '{$1="";print}' | rev | awk 'gsub(" ",".") ,sub(".$", "")'
abc.a
a.b.c
pp-kk
filename$ find . -type f | awk -F/ '{print $2}' | awk -F"." '{print $NF}'
txt
txt
txt

Use find for name "a" and execute rm to remove those named according to your wishes, as follows:

find . -name a -exec rm -rf {} \;

Test it first using ls to list:

find . -name a -exec ls {} \;

To ensure this only removes directories and not plain files, use the "-type d" arg (as suggested in the comments):

find . -name a -type d -exec rm -rf {} \;

The "{}" is a substitution for each file "a" found - the exec command is executed against each by substitution.

A variation in JavaScript using reduce

const getProduct = arr => arr.reduce((acc, value) => acc * value);_x000D_
_x000D_
const arrayWithExclusion = (arr, node) =>_x000D_
  arr.reduce((acc, val, j) => (node !== j ? [...acc, val] : acc), []);_x000D_
_x000D_
const getProductWithExclusion = arr => {_x000D_
  let result = [];_x000D_
_x000D_
  for (let i = 0; i < arr.length; i += 1) {_x000D_
    result.push(getProduct(arrayWithExclusion(arr, i)));_x000D_
  }_x000D_
_x000D_
  return result;_x000D_
};

Suppose company C offers product P and P involves software in some way. Then C can offer a library/set of libraries to software developers that drive P's software systems.

That library/libraries are an SDK. It is part of the systems of P. It is a kit for software developers to use in order to modify, configure, fix, improve, etc the software piece of P.

If C wants to offer P's functionality to other companies/systems, it does so with an API.

This is an interface to P. A way for external systems to interact with P.

If you think in terms of implementation, they will seem quite similar. Especially now that the internet has become like one large distributed operating system.

In purpose, though, they are actually quite distinct.

You build something with an SDK and you use or consume something with an API.

Nothing worked for me until I encoded the video properly. Try this guide for the correct handbrake settings: http://forum.handbrake.fr/viewtopic.php?f=7&t=9694

I just came up with this neat workaround

var firstChar = Array(string)[0]

Using JQuery:

var color = $('#myDivID').css("background-color");

The key checks for FAST REFRESH includes the following:

1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.

No 3 is easy to miss and worth highlighting here

As of the latest Bootstrap (3.1.x), the way to achieve a fluid layout it to use .container-fluid class.

See Bootstrap grid for reference

The SSL certificates are going to be bound to hostname rather than IP if they are setup in the standard way. Hence why it works at one site rather than the other.

Even if the servers share the same hostname they may well have two different certificates and hence WebSphere will have a certificate trust issue as it won't be able to recognise the certificate on the second server as it is different to the first.

json:
[{"ew":"vehicles","hws":["car","van","bike","plane","bus"]},{"ew":"countries","hws":["America","India","France","Japan","South Africa"]}]

c# code: to take only a single value, for example the word "bike".

//res=[{"ew":"vehicles","hws":["car","van","bike","plane","bus"]},{"ew":"countries","hws":["America","India","France","Japan","South Africa"]}]

         dynamic stuff1 = Newtonsoft.Json.JsonConvert.DeserializeObject(res);
         string Text = stuff1[0].hws[2];
         Console.WriteLine(Text);

output:

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

Using recursion, you're incurring the cost of a function call with each "iteration", whereas with a loop, the only thing you usually pay is an increment/decrement. So, if the code for the loop isn't much more complicated than the code for the recursive solution, loop will usually be superior to recursion.

both your conditions are the same:

if(s < f) {     calc = f - s;     n = s; }else if(f > s){     calc =  s - f;     n = f;  } 

so

if(s < f)   

and

}else if(f > s){ 

are the same

change to

}else if(f < s){ 

For your use case, it may be easier to utilize a while loop.

t1 = [137, 42]
t2 = ["Hello", "world"]

i = 0
j = 0
while i < len(t1) and j < len(t2):
    print t1[i], t2[j]
    i += 1
    j += 1

# 137 Hello
# 42 world

As a caveat, this approach will truncate to the length of your shortest list.

Or, if you're kicking it old school:

cd /path/to/other/repository
patch -p1 < 0001-whatever.patch

input[type=text]

This will select all the input type text in a web-page.

I've accepted Fredriks answer as it appears to solve the problem with the least amount of effort however the Request object doesn't appear to conatin the ResolveUrl method. This can be accessed through the Page object or an Image control object:

myImage.ImageUrl = Page.ResolveUrl(photoURL);
myImage.ImageUrl = myImage.ResolveUrl(photoURL);

An alternative, if you are using a static class as I am, is to use the VirtualPathUtility:

myImage.ImageUrl = VirtualPathUtility.ToAbsolute(photoURL);

I'll give my input because it helps me understand what im doing.

To make an auto scrolling slide show that has a 3 second wait I did the following:

var isPlaying = true;

function autoPlay(playing){
   var delayTime = 3000;
   var timeIncrement = 3000;

   if(playing){
        for(var i=0; i<6; i++){//I have 6 images
            setTimeout(nextImage, delayTime);
            delayTime += timeIncrement;
        }
        isPlaying = false;

   }else{
       alert("auto play off");
   }
}

autoPlay(isPlaying);

Remember that when executing setTimeout() like this; it will execute all time out functions as if they where executed at the same time assuming that in setTimeout(nextImage, delayTime);delay time is a static 3000 milliseconds.

What I did to account for this was add an extra 3000 milli/s after each for loop incrementation via delayTime += timeIncrement;.

For those who care here is what my nextImage() looks like:

function nextImage(){
    if(currentImg === 1){//change to img 2
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[1].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[1];
        imgDescription.innerHTML = imgDescText[1];

        currentImg = 2;
    }
    else if(currentImg === 2){//change to img 3
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[2].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[2];
        imgDescription.innerHTML = imgDescText[2];

        currentImg = 3;
    }
    else if(currentImg === 3){//change to img 4
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[3].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[3];
        imgDescription.innerHTML = imgDescText[3];

        currentImg = 4;
    }
    else if(currentImg === 4){//change to img 5
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[4].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[4];
        imgDescription.innerHTML = imgDescText[4];

        currentImg = 5;
    }
    else if(currentImg === 5){//change to img 6
    for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[5].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[5];
        imgDescription.innerHTML = imgDescText[5];

        currentImg = 6;
    }
    else if(currentImg === 6){//change to img 1
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[0].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[0];
        imgDescription.innerHTML = imgDescText[0];

        currentImg = 1;
    }
}

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

you can just append another hidden img element and swap them in onload event.

Or use single image element and use javascript like:

var _img = document.getElementById('id1');
var newImg = new Image;
newImg.onload = function() {
    _img.src = this.src;
}
newImg.src = 'http://whatever';

this code should preload the image and show it when it's ready

Let's consider that you have input as "1,2,3,4".

That means the length of the input is 7. So now you write the size = 7/2 = 3.5. But as size is an int, it will be rounded off to 3. In short, you are losing 1 value.

If you rewrite the code as below it should work:

String input;
int length, count, size;
Scanner keyboard = new Scanner(System.in);
input = keyboard.next();
length = input.length();

String strarray[] = input.split(",");
int intarray[] = new int[strarray.length];

for (count = 0; count < intarray.length ; count++) {
    intarray[count] = Integer.parseInt(strarray[count]);
}

for (int s : intarray) {
    System.out.println(s);
}

It seems you are looking for the Post/Redirect/Get pattern.

As another solution you may stop to use redirecting at all.

You may process and render the processing result at once with no POST confirmation alert. You should just manipulate the browser history object:

history.replaceState("", "", "/the/result/page")

I'm new in R, but I was using this easy method that works for me:

sample_of_diamonds <- diamonds[sample(nrow(diamonds),100),]

PS: Feel free to note if it has some drawback I'm not thinking about.

you may try this one, used CONCAT

WHERE LastName LIKE Concat('%',@LastName,'%')

I was getting the error. I simply added "proxy" in my package.json and the error went away. The error was simply there because the API request was getting made at the same port as the react app was running. You need to provide the proxy so that the API call is made to the port where your backend server is running.

Taking this one step further, to save a file to a relative directory, you can use the replace function. Say you have your workbook saved in: c:\property\california\sacramento\workbook.xlsx, use this to move the property to berkley:

workBookPath = Replace(ActiveWorkBook.path, "sacramento", "berkley")
myWorkbook.SaveAs(workBookPath & "\" & "newFileName.xlsx"

Only works if your file structure contains one instance of the text used to replace. YMMV.

If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m

Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini file which is present in your Eclipse home directory.

To get the size of the JVM during Runtime you can use Runtime.totalMemory() which returns the total amount of memory in the Java virtual machine, measured in bytes.

1. Can I replace the toggle text with an image

   No, we can not, although we can hide the text by overiding the default style of the toggle button, but still that won't give us a toggle button you want as we can't replace the text with an image.

2. How can I make a normal toggle button

   Create a file ic_toggle in your res/drawable folder

   <selector xmlns:android="http://schemas.android.com/apk/res/android">
   
       <item android:state_checked="false"
             android:drawable="@drawable/ic_slide_switch_off" />
   
       <item android:state_checked="true"
             android:drawable="@drawable/ic_slide_switch_on" />
   
   </selector>
   

   Here @drawable/ic_slide_switch_on & @drawable/ic_slide_switch_off are images you create.

   Then create another file in the same folder, name it ic_toggle_bg

   <?xml version="1.0" encoding="utf-8"?>
   <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   
       <item android:id="@+android:id/background"  
             android:drawable="@android:color/transparent" />
   
       <item android:id="@+android:id/toggle"
             android:drawable="@drawable/ic_toggle" />
   
   </layer-list>
   

   Now add to your custom theme, (if you do not have one create a styles.xml file in your res/values/folder)

   <style name="Widget.Button.Toggle" parent="android:Widget">
      <item name="android:background">@drawable/ic_toggle_bg</item>
      <item name="android:disabledAlpha">?android:attr/disabledAlpha</item>
   </style>
   
   <style name="toggleButton"  parent="@android:Theme.Black">
      <item name="android:buttonStyleToggle">@style/Widget.Button.Toggle</item>
      <item name="android:textOn"></item>
      <item name="android:textOff"></item>
   </style>
   

   This creates a custom toggle button for you.

3. How to use it

   Use the custom style and background in your view.

     <ToggleButton
           android:id="@+id/toggleButton"
           android:layout_width="wrap_content"
           android:layout_height="match_parent"
           android:layout_gravity="right"
           style="@style/toggleButton"
           android:background="@drawable/ic_toggle_bg"/>
   

The following works:

http://jsfiddle.net/xAGRJ/4/

The problem with your original code was you are calling scrollticker() by passing a string to setInterval, where you should just pass the function name and treat it as a variable:

lefttime = setInterval(scrollticker, 50);

instead of

lefttime = setInterval("scrollticker()", 50);

This answer is very late but what I do is set a class that holds Booleans, arrays, and integer-initial values as global scope static variables. Any constant strings are defined as such.

define("myconstant", "value"); 

class globalVars {

    static $a = false;

    static $b = 0;

    static $c = array('first' => 2, 'second' => 5);

}


function test($num) {

    if (!globalVars::$a) {

        $returnVal = 'The ' . myconstant . ' of ' . $num . ' plus ' . globalVars::$b . ' plus ' . globalVars::$c['second'] . ' is ' . ($num + globalVars::$b + globalVars::$c['second']) . '.';

        globalVars::$a = true;

    } else {

        $returnVal = 'I forgot';

    }

    return $returnVal;

}

echo test(9); ---> The value of 9 + 0 + 5 is 14.

echo "<br>";

echo globalVars::$a; ----> 1

The static keywords must be present in the class else the vars $a, $b, and $c will not be globally scoped.

Avoid direct references to '@@ERROR'. It's a flighty little thing that can be lost.

Declare @ErrorCode int;
... perform stuff ...
Set @ErrorCode = @@ERROR;
... other stuff ...
if @ErrorCode ...... 

Based on @ideasman42's suggestion in his answer, this is a macro that provides int8,16,32 & 64 versions, reusing the INT8 macro to avoid repetition.

The point is to set the token on the interceptors for each request

import axios from "axios";
    
const httpClient = axios.create({
    baseURL: "http://youradress",
    // baseURL: process.env.APP_API_BASE_URL,
});

httpClient.interceptors.request.use(function (config) {
    const token = localStorage.getItem('token');
    config.headers.Authorization =  token ? `Bearer ${token}` : '';
    return config;
});

the above query only works if we have created clients table with matching columns of the customer

INSERT INTO clients(c_id,name,address)SELECT c_id,name,address FROM customer

What role do they play when exiting an application in C#?

The same as every other application. Basically they get returned to the caller. Irrelvant if ythe start was an iicon double click. Relevant is the call is a batch file that decides whether the app worked on the return code. SO, unless you write a program that needs this, the return dcode IS irrelevant.

But what is the difference?

One comes from environment one from the System.Windows.Forms?.Application. Functionall there should not bbe a lot of difference.

Laravel 5 gets its enviroment related variables from the .env file located in the root of your project. You just need to set APP_ENV to whatever you want, for example:

APP_ENV=development

This is used to identify the current enviroment. If you want to display errors, you'll need to enable debug mode in the same file:

APP_DEBUG=true

The role of the .env file is to allow you to have different settings depending on which machine you are running your application. So on your production server, the .env file settings would be different from your local development enviroment.

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

The browser extension uBlock’s setting “Block remote fonts” will cause this error. (Note: Grammarly was not the problem, at least for me.)

Usually this isn’t a problem. When a remote font is blocked, you fall back to some other font and a console warning saying “ERR_BLOCKED_BY_CLIENT” is issued. However, this can be a serious problem when a site uses Font Awesome, because the icons show as boxes.

There’s not much a website can do about fixing this (but you can prevent it from being too bad by e.g. labeling font-based icons). Changing the CSP (or adding one) will not fix it. Serving the fonts from your website (and not a CDN) will not fix it either.

The uBlock user, on the other hand, has the power to fix this by doing one of the following:

• Uncheck the option globally in the dashboard for the extension
• Navigate to your website and click on the extension icon, then on the crossed out ‘A’ icon to not block fonts just for that site
• Disable uBlock for your site by adding it to the whitelist in the extension’s dashboard

What's not mentioned here is that option 1 allows you arbitrarily deep nesting of lists.

This shouldn't matter if you control the content/css, but if you're making a rich text editor it comes in handy.

For example, gmail, inbox, and evernote all allow creating lists like this:

With option 2 you cannot due that (you'll have an extra list item), with option 1, you can.

Raising ActionController::RoutingError('not found') has always felt a little bit strange to me - in the case of an unauthenticated user, this error does not reflect reality - the route was found, the user is just not authenticated.

I happened across config.action_dispatch.rescue_responses and I think in some cases this is a more elegant solution to the stated problem:

# application.rb
config.action_dispatch.rescue_responses = {
  'UnauthenticatedError' => :not_found
}

# my_controller.rb
before_action :verify_user_authentication

def verify_user_authentication
  raise UnauthenticatedError if !user_authenticated?
end

What's nice about this approach is:

1. It hooks into the existing error handling middleware like a normal ActionController::RoutingError, but you get a more meaningful error message in dev environments
2. It will correctly set the status to whatever you specify in the rescue_responses hash (in this case 404 - not_found)
3. You don't have to write a not_found method that needs to be available everywhere.

Try the following:

CONVERT(varchar(10), [MyDateTimecolumn], 20)

For a full date time and not just date do:

CONVERT(varchar(23), [MyDateTimecolumn], 121)

See this page for convert styles:

http://msdn.microsoft.com/en-us/library/ms187928.aspx
OR
SQL Server CONVERT() Function

Why is that not acceptable?

document.getElementById('test').innerHTML += str

would be the textbook way of doing it.

Use waitpid() like this:

pid_t childPid;  // the child process that the execution will soon run inside of. 
childPid = fork();

if(childPid == 0)  // fork succeeded 
{   
   // Do something   
   exit(0); 
}

else if(childPid < 0)  // fork failed 
{    
   // log the error
}

else  // Main (parent) process after fork succeeds 
{    
    int returnStatus;    
    waitpid(childPid, &returnStatus, 0);  // Parent process waits here for child to terminate.

    if (returnStatus == 0)  // Verify child process terminated without error.  
    {
       printf("The child process terminated normally.");    
    }

    if (returnStatus == 1)      
    {
       printf("The child process terminated with an error!.");    
    }
}

The global type Function serves this purpose.

Additionally, if you intend to invoke this callback with 0 arguments and will ignore its return value, the type () => void matches all functions taking no arguments.

Update with details and improvements.

The answer and question here has way too many updoots not to mention the only-slightly more complex yet best-practice method:

Solution to your question

interface Easy_Fix_Solution {
    title: string;
    callback: Function;
}

NOTE: Please do not use Function as you most likely do not want any callback function. It's okay to be a little specific.

Improvement to that solution

interface Safer_Easy_Fix {
    title: string;
    callback: () => void;
}
interface Alternate_Syntax_4_Safer_Easy_Fix {
    title: string;
    callback(): void;
}

NOTE: The original author is correct, accepting no arguments and returning void is better.. it's much safer, it tells the consumer of your interface that you will not be doing anything with their return value, and that you will not be passing them any parameters.

And better yet Use generics. This interface would also work for the same () => void function types mentioned before.

interface Better_still_safe_but_way_more_flexible_fix {
    title: string;
    callback: <T = unknown, R = unknown>(args?: T) => R;
}
interface Alternate_Syntax_4_Better_still_safe_but_way_more_flexible_fix {
    title: string;
    callback<T = unknown, R = unknown>(args?: T): R;
}

NOTE: If you aren't 100% sure about the callback signature right now, please choose the void option above, or this generic option if you think you may extend functionality going forward. Callbacks usually receive some arguments of some sort, and sometimes the callback orchestrator even does something with the return value.

And a slightly more advanced usecase you shouldn't use unless you need it

This allows any number of arguments, of any type in T.

More details here.

interface Alternate_Syntax_4_Advanced {
    title: string;
    callback<T extends unknown[], R = unknown>(...args?: T): R;
}

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

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

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

From official documentation :

To enable Google to crawl your app content and allow users to enter your app from search results, you must add intent filters for the relevant activities in your app manifest. These intent filters allow deep linking to the content in any of your activities. For example, the user might click on a deep link to view a page within a shopping app that describes a product offering that the user is searching for.

Using this link Enabling Deep Links for App Content you'll see how to use it.

And using this Test Your App Indexing Implementation how to test it.

The following XML snippet shows how you might specify an intent filter in your manifest for deep linking.

<activity
    android:name="com.example.android.GizmosActivity"
    android:label="@string/title_gizmos" >
    <intent-filter android:label="@string/filter_title_viewgizmos">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
        <data android:scheme="http"
              android:host="www.example.com"
              android:pathPrefix="/gizmos" />
        <!-- note that the leading "/" is required for pathPrefix-->
        <!-- Accepts URIs that begin with "example://gizmos” -->
        <data android:scheme="example"
              android:host="gizmos" />

    </intent-filter>
</activity>

To test via Android Debug Bridge

$ adb shell am start
        -W -a android.intent.action.VIEW
        -d <URI> <PACKAGE>

$ adb shell am start
        -W -a android.intent.action.VIEW
        -d "example://gizmos" com.example.android

Swift 4.2 version:

import UIKit

class InsetTextField: UITextField {

  let inset: CGFloat = 10

  override func textRect(forBounds bounds: CGRect) -> CGRect {
    return bounds.insetBy(dx: inset, dy: inset)
  }


  override func editingRect(forBounds bounds: CGRect) -> CGRect {
    return bounds.insetBy(dx: inset, dy: inset)
  }

  override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
    return bounds.insetBy(dx: inset, dy: inset)
  }

}

One way, provide --user flag as part of curl, as follows:

curl --user username:password http://example.com

Another way is to get Base64 encoded token of "username:password" from any online website like - https://www.base64encode.org/ and pass it as Authorization header of curl as follows:

curl -i -H 'Authorization:Basic dXNlcm5hbWU6cGFzc3dvcmQ=' http://localhost:8080/

Here, dXNlcm5hbWU6cGFzc3dvcmQ= is Base64 encoded token of username:password.

Add this style to your span:

position:relative; 
top: 10px;

There's a bit of confusion in your question:

• a Date datatype doesn't save the time zone component. This piece of information is truncated and lost forever when you insert a TIMESTAMP WITH TIME ZONE into a Date.
• When you want to display a date, either on screen or to send it to another system via a character API (XML, file...), you use the TO_CHAR function. In Oracle, a Date has no format: it is a point in time.
• Reciprocally, you would use TO_TIMESTAMP_TZ to convert a VARCHAR2 to a TIMESTAMP, but this won't convert a Date to a TIMESTAMP.
• You use FROM_TZ to add the time zone information to a TIMESTAMP (or a Date).
• In Oracle, CST is a time zone but CDT is not. CDT is a daylight saving information.
• To complicate things further, CST/CDT (-05:00) and CST/CST (-06:00) will have different values obviously, but the time zone CST will inherit the daylight saving information depending upon the date by default.

So your conversion may not be as simple as it looks.

Assuming that you want to convert a Date d that you know is valid at time zone CST/CST to the equivalent at time zone CST/CDT, you would use:

SQL> SELECT from_tz(d, '-06:00') initial_ts,
  2         from_tz(d, '-06:00') at time zone ('-05:00') converted_ts
  3    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  4                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  5            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
09/10/12 01:10:21,000000 -06:00 09/10/12 02:10:21,000000 -05:00

My default timestamp format has been used here. I can specify a format explicitely:

SQL> SELECT to_char(from_tz(d, '-06:00'),'yyyy-mm-dd hh24:mi:ss TZR') initial_ts,
  2         to_char(from_tz(d, '-06:00') at time zone ('-05:00'),
  3                 'yyyy-mm-dd hh24:mi:ss TZR') converted_ts
  4    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  5                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  6            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
2012-10-09 01:10:21 -06:00      2012-10-09 02:10:21 -05:00

Another MySQL option that may look more like Oracle's DECODE is a combination of FIELD and ELT. In the code that follows, FIELD() returns the argument list position of the string that matches Age. ELT() returns the string from ELTs argument list at the position provided by FIELD(). For example, if Age is 14, FIELD(Age, ...) returns 2 because 14 is the 2nd argument of FIELD (not counting Age). Then, ELT(2, ...) returns 'Fourteen', which is the 2nd argument of ELT (not counting the FIELD() argument). IFNULL returns the default AgeBracket if no match to Age is found in the list.

Select Name, IFNULL(ELT(FIELD(Age,
       13, 14, 15, 16, 17, 18, 19),'Thirteen','Fourteen','Fifteen','Sixteen',
       'Seventeen','Eighteen','Nineteen'),
       'Adult') AS AgeBracket
FROM Person

While I don't think this is the best solution to the question either in terms of performance or readability it is interesting as an exploration of MySQL's string functions. Keep in mind that FIELD's output does not seem to be case sensitive. I.e., FIELD('A','A') and FIELD('a','A') both return 1.

I'm the one who donated the Ant export filter to Eclipse. I added the auto export feature, but only to my personal plug-in eclipse2ant, which I still maintain to coordinate bug fixes.

Unfortunately I have no time to merge it to the official Eclipse builds.

rt.jar contains all of the compiled class files for the base Java Runtime environment. You should not be messing with this jar file.

For MacOS it is called classes.jar and located under /System/Library/Frameworks/<java_version>/Classes . Same not messing with it rule applies there as well :).

You can try the following code to get time as HH:MM format:

 SELECT CONVERT(VARCHAR(5),getdate(),108)

Updated to Swift 3:

Instead of the flow layout, I prefer using custom layout for specific column number and row number. Because:

1. It can be dragged horizontally if column number is very big.
2. It is more acceptable logically because of using column and row.

Normal cell and Header cell: (Add UILabel as a IBOutlet to your xib):

class CollectionViewCell: UICollectionViewCell {

@IBOutlet weak var label: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
    self.backgroundColor = UIColor.black
    label.textColor = UIColor.white
}
}

class CollectionViewHeadCell: UICollectionViewCell {

@IBOutlet weak var label: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
    self.backgroundColor = UIColor.darkGray
    label.textColor = UIColor.white
}
}

Custom layout:

let cellHeight: CGFloat = 100
let cellWidth: CGFloat = 100

class CustomCollectionViewLayout: UICollectionViewLayout {
    private var numberOfColumns: Int!
    private var numberOfRows: Int!

    // It is two dimension array of itemAttributes
    private var itemAttributes = [[UICollectionViewLayoutAttributes]]()
    // It is one dimension of itemAttributes
    private var cache = [UICollectionViewLayoutAttributes]()

override func prepare() {
    if self.cache.isEmpty {

        self.numberOfColumns = self.collectionView?.numberOfItems(inSection: 0)
        self.numberOfRows = self.collectionView?.numberOfSections

        // Dynamically change cellWidth if total cell width is smaller than whole bounds
        /* if (self.collectionView?.bounds.size.width)!/CGFloat(self.numberOfColumns) > cellWidth {
         self.cellWidth = (self.collectionView?.bounds.size.width)!/CGFloat(self.numberOfColumns)
         }
         */
        for row in 0..<self.numberOfRows {
            var row_temp = [UICollectionViewLayoutAttributes]()
            for column in 0..<self.numberOfColumns {

                let indexPath = NSIndexPath(item: column, section: row)

                let attributes = UICollectionViewLayoutAttributes(forCellWith: indexPath as IndexPath)
                attributes.frame = CGRect(x: cellWidth*CGFloat(column), y: cellHeight*CGFloat(row), width: cellWidth, height: cellHeight)

                row_temp.append(attributes)

                self.cache.append(attributes)
            }
            self.itemAttributes.append(row_temp)
        }
    }
}
override var collectionViewContentSize: CGSize {
    return CGSize(width: CGFloat(self.numberOfColumns)*cellWidth, height: CGFloat(self.numberOfRows)*cellHeight)
}

override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {

    var layoutAttributes = [UICollectionViewLayoutAttributes]()

    for attributes in cache {
        if attributes.frame.intersects(rect) {
            layoutAttributes.append(attributes)
        }
    }
    return layoutAttributes
}
}

CollectionView:

let CellIdentifier = "CellIdentifier"
let HeadCellIdentifier = "HeadCellIdentifier"

class CollectionView: UICollectionView, UICollectionViewDelegate, UICollectionViewDataSource {

init() {
    let layout = CustomCollectionViewLayout()

    super.init(frame: CGRect.zero, collectionViewLayout: layout)

    self.register(UINib(nibName: "CollectionViewCell", bundle: nil), forCellWithReuseIdentifier: CellIdentifier)
    self.register(UINib(nibName: "CollectionViewHeadCell", bundle: nil), forCellWithReuseIdentifier: HeadCellIdentifier)

    self.isDirectionalLockEnabled = true
    self.dataSource = self
    self.delegate = self
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

func updateCollectionView() {
    DispatchQueue.main.async {
        self.reloadData()
    }
}

// MARK: CollectionView datasource
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 20
}
func numberOfSections(in collectionView: UICollectionView) -> Int {
    return 20
}
override func numberOfItems(inSection section: Int) -> Int {
    return 20
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let column = (indexPath as NSIndexPath).row
    let row = (indexPath as NSIndexPath).section

    if column == 0 {
        let cell : CollectionViewHeadCell = collectionView.dequeueReusableCell(withReuseIdentifier: HeadCellIdentifier, for: indexPath) as! CollectionViewHeadCell

        cell.label.text = "\(row)"

        return cell
    }
    else if row == 0 {
        let cell : CollectionViewHeadCell = collectionView.dequeueReusableCell(withReuseIdentifier: HeadCellIdentifier, for: indexPath) as! CollectionViewHeadCell

        cell.label.text = "\(column)"

        return cell
    }
    else {
        let cell : CollectionViewCell = collectionView.dequeueReusableCell(withReuseIdentifier: CellIdentifier, for: indexPath) as! CollectionViewCell

        cell.label.text = String(format: "%d", arguments: [indexPath.section*indexPath.row])

        return cell
    }
}

// MARK: CollectionView delegate
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    let column = (indexPath as NSIndexPath).row
    let row = (indexPath as NSIndexPath).section

    print("\(column)  \(row)")
}
}

Use CollectionView from ViewController:

class ViewController: UIViewController {
let collectionView = CollectionView()

override func viewDidLoad() {
    collectionView.translatesAutoresizingMaskIntoConstraints = false
    self.view.addSubview(collectionView)
    self.view.backgroundColor = UIColor.red

    self.view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|[collectionView]|", options: [], metrics: nil, views: ["collectionView": collectionView]))
    self.view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[collectionView]|", options: [], metrics: nil, views: ["collectionView": collectionView]))
}

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    collectionView.updateCollectionView()
}
}

Finally you can have fancy CollectionView!

Not sure if this fits here, but I had similar question and found following simple solution/example for me:

private EntityManager entityManager;
...
    final String sql = " SELECT * FROM STORE "; // select from the table STORE
    final Query sqlQuery = entityManager.createNativeQuery(sql, Store.class);

    @SuppressWarnings("unchecked")
    List<Store> results = (List<Store>) sqlQuery.getResultList();

In my case I had to use SQL parts defined in Strings somewhere else, so I could not just use NamedNativeQuery.

Actually quite easy to roll your own tester, by abusing Java's method overload ability. Though I'm still curious if there is an official method in the sdk.

Example:

class Typetester {
    void printType(byte x) {
        System.out.println(x + " is an byte");
    }
    void printType(int x) {
        System.out.println(x + " is an int");
    }
    void printType(float x) {
        System.out.println(x + " is an float");
    }
    void printType(double x) {
        System.out.println(x + " is an double");
    }
    void printType(char x) {
        System.out.println(x + " is an char");
    }
}

then:

Typetester t = new Typetester();
t.printType( yourVariable );

in my case i want something like

[10,5,15,20,25] -> [ 2, 1, 3, 4, 5 ]

function ratio(array){_x000D_
  let min = Math.min(...array);_x000D_
  let ratio = array.map((element)=>{_x000D_
    return element/min;_x000D_
  });_x000D_
  return ratio;_x000D_
}_x000D_
document.write(ratio([10,5,15,20,25]));  // [ 2, 1, 3, 4, 5 ]

To do that, you must remove all ' charachters in your string or use an escape character. Like:

<?php
    echo '<?php
              echo \'hello world\';
          ?>';
?>

You are actually trying to redirect a page which has some response to throw. So first you keep the information you have throw in a buffer using response.buffer = true in beginning of the page and then flush it when required using response.flush this error will get fixed

I understand you want to open a xml file using php. That's called to parse a xml file. The best reference is here.

http://php.net/manual/de/function.xml-parse.php

My solution:

let isEmpty = (val) => {
    let typeOfVal = typeof val;
    switch(typeOfVal){
        case 'object':
            return (val.length == 0) || !Object.keys(val).length;
