JQUERY FORMATCURRENCY PLUGIN
http://code.google.com/p/jquery-formatcurrency/

This is the way:

/usr/bin/php -q /home/username/public_html/yourfilename.php >/dev/null

You can use print_r to get human-readable output. But to display it as text we add "echo '';"

echo ''; print_r($row);

Use a lambda expression

MyClass result = list.Find(x => x.GetId() == "xy");

Note: C# has a built-in syntax for properties. Instead of writing getter and setter methods (as you might be used to from Java), write

private string _id;
public string Id
{
    get
    {
        return _id;
    }
    set
    {
        _id = value;
    }
}

value is a contextual keyword known only in the set accessor. It represents the value assigned to the property.

Since this pattern is often used, C# provides auto-implemented properties. They are a short version of the code above; however, the backing variable is hidden and not accessible (it is accessible from within the class in VB, however).

public string Id { get; set; }

You can simply use properties as if you were accessing a field:

var obj = new MyClass();
obj.Id = "xy";       // Calls the setter with "xy" assigned to the value parameter.
string id = obj.Id;  // Calls the getter.

Using properties, you would search for items in the list like this

MyClass result = list.Find(x => x.Id == "xy"); 

You can also use auto-implemented properties if you need a read-only property:

public string Id { get; private set; }

This enables you to set the Id within the class but not from outside. If you need to set it in derived classes as well you can also protect the setter

public string Id { get; protected set; }

And finally, you can declare properties as virtual and override them in deriving classes, allowing you to provide different implementations for getters and setters; just as for ordinary virtual methods.

Since C# 6.0 (Visual Studio 2015, Roslyn) you can write getter-only auto-properties with an inline initializer

public string Id { get; } = "A07"; // Evaluated once when object is initialized.

You can also initialize getter-only properties within the constructor instead. Getter-only auto-properties are true read-only properties, unlike auto-implemented properties with a private setter.

This works also with read-write auto-properties:

public string Id { get; set; } = "A07";

Beginning with C# 6.0 you can also write properties as expression-bodied members

public DateTime Yesterday => DateTime.Date.AddDays(-1); // Evaluated at each call.
// Instead of
public DateTime Yesterday { get { return DateTime.Date.AddDays(-1); } }

See: .NET Compiler Platform ("Roslyn")
         New Language Features in C# 6

Starting with C# 7.0, both, getter and setter, can be written with expression bodies:

public string Name
{
    get => _name;                                // getter
    set => _name = value;                        // setter
}

Note that in this case the setter must be an expression. It cannot be a statement. The example above works, because in C# an assignment can be used as an expression or as a statement. The value of an assignment expression is the assigned value where the assignment itself is a side effect. This allows you to assign a value to more than one variable at once: x = y = z = 0 is equivalent to x = (y = (z = 0)) and has the same effect as the statements x = 0; y = 0; z = 0;.

The next version of the language, C# 9.0, probably available in November 2020, will allow read-only (or better initialize-once) properties that you can initialize in an object initializer. This is currently not possible with getter-only properties.

public string Name { get; init; }

var c = new C { Name = "c-sharp" };

Using a user-defined variable within a query makes the query resuts uncacheable. I found it a much better indicator than using SQL_NO_CACHE. But you should put the variable in a place where the variable setting would not seriously affect the performance:

SELECT t.*
FROM thetable t, (SELECT @a:=NULL) as init;

This works to me.

<div id="demo">
        <h2>Demo</h2>
</div>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script>
    $(document).ready(function () {
        // Handler for .ready() called.
        $('html, body').animate({
            scrollTop: $('#demo').offset().top
        }, 'slow');
    });
</script>

Thanks.

The values() method returns a QuerySet containing dictionaries:

<QuerySet [{'comment_id': 1}, {'comment_id': 2}]>

The values_list() method returns a QuerySet containing tuples:

<QuerySet [(1,), (2,)]>

If you are using values_list() with a single field, you can use flat=True to return a QuerySet of single values instead of 1-tuples:

<QuerySet [1, 2]>

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

<script>var myVar = 15;</script>
<input id="EditBanner" type="button" value="Edit Image" onclick="EditBanner(myVar);"/>

These days even if the spec doesn't allow it, it "seems" to still work to embed the button within a <a href...><button ...></a> tag, FWIW...

Unfortunately all above didn't work for me. After having lots of trials, What worked for me in Android Studio:

1. do a 'move' on the package to a new package name you want.(right click on package and select Refactor -> Move) If Refactor -> Move didn't work for you, then create a package with the name you want and move manually in the existing package to the new one, and then delete the old empty package.

2. Change package name in manifest (manually)

3. Have a replace for the old package name with the new package name globally (in the full path by going to Edit -> Find -> Replace In Path)

To answer your main question: “How do I simulate a hover with a touch in touch enabled browsers?”

Simply allow ‘clicking’ the element (by tapping the screen), and then trigger the hover event using JavaScript.

var p = document.getElementsByTagName('p')[0];
p.onclick = function() {
 // Trigger the `hover` event on the paragraph
 p.onhover.call(p);
};

This should work, as long as there’s a hover event on your device (even though it normally isn’t used).

Update: I just tested this technique on my iPhone and it seems to work fine. Try it out here: http://jsfiddle.net/mathias/YS7ft/show/light/

If you want to use a ‘long touch’ to trigger hover instead, you can use the above code snippet as a starting point and have fun with timers and stuff ;)

You want hasOwnProperty():

var myObj1 = { _x000D_
 prop1: 'no',_x000D_
 prop2: function () { return false; }_x000D_
}_x000D_
var myObj2 = { _x000D_
 prop1: 'no'_x000D_
}_x000D_
_x000D_
console.log(myObj1.hasOwnProperty('prop2')); // returns true_x000D_
console.log(myObj2.hasOwnProperty('prop2')); // returns false_x000D_

Need to support old browser and have a object hierarchy

body.head.eyes[0]  //body, head, eyes  may be null 

may use this,

(((body||{}) .head||{}) .eyes||[])[0] ||'left eye'

I was having the same problem. It ended up being the jquery.dimensions.js plugin. If I removed it, everything worked fine. I included it because of another plugin that required it, however I found out from the link here that dimensions was included in the jQuery core quite a while ago (http://api.jquery.com/category/dimensions). You should be ok simply getting rid of the dimensions plugin.

I was looking through a ton of java code for a specific library: car.csclh.server.isr.businesslogic.TypePlatform (although I only knew car and Platform at the time). Unfortunately, none of the other suggestions here worked for me, so I figured I'd post this.

Here's the regex I used to find it:

JSON.stringify takes more optional arguments.

Try:

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

From:

How can I beautify JSON programmatically?

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

I made a script to solve this which is here. You don't need any extra software for this. Installation:
brew install akashaggarwal7/tools/tsay
Usage:
sleep 5; tsay

It work for me

$request = new Request();
$request->headers->set('content-type', 'application/json');     
$request->initialize(['yourParam' => 2]);

check output

$queryParams = $request->query();
dd($queryParams['yourParam']); // 2

I am using ,Mongo 3.4.0

The $rename operator updates the name of a field and has the following form:

{$rename: { <field1>: <newName1>, <field2>: <newName2>, ... } }

for e.g

db.getCollection('user').update( { _id: 1 }, { $rename: { 'fname': 'FirstName', 'lname': 'LastName' } } )

The new field name must differ from the existing field name. To specify a in an embedded document, use dot notation.

This operation renames the field nmae to name for all documents in the collection:

db.getCollection('user').updateMany( {}, { $rename: { "add": "Address" } } )

db.getCollection('user').update({}, {$rename:{"name.first":"name.FirstName"}}, false, true);

In the method above false, true are: { upsert:false, multi:true }.To update all your records, You need the multi:true.

Rename a Field in an Embedded Document

db.getCollection('user').update( { _id: 1 }, { $rename: { "name.first": "name.fname" } } )

use link : https://docs.mongodb.com/manual/reference/operator/update/rename/

Simply write outline:none;. No need to use pseudo element focus

This is how I feed my table with data retrieved by ajax (not sure if this is the best practice tough, but it feels intuitive and works well):

/* initialise table */
oTable1 = $( '.tables table' ).dataTable
( {
    'sPaginationType': 'full_numbers',
    'bLengthChange': false,
    'aaData': [],
    'aoColumns': [{"sTitle": "Tables"}],
    'bAutoWidth': true
} );


 /*retrieve data*/
function getArr( conf_csv_path )
{
    $.ajax
    ({
        url  : 'my_url'
        success  : function( obj ) 
        {
            update_table( obj );
        }
    });
}


/* build table data */
function update_table( arr )
{        
    oTable1.fnClearTable();
    for ( input in arr )
    {
        oTable1.fnAddData( [ arr[input] );
    }                                
}

You can try FileUtils from org.apache.commons.io.FileUtils, try downloading jar from here

and you can use the following method: FileUtils.readFileToString("yourFileName");

Hope it helps you..

I don't have an 11g instance available today but could you not use:

SELECT group_id,
       LISTAGG(name, ',') WITHIN GROUP (ORDER BY name) AS names
  FROM (
       SELECT UNIQUE
              group_id,
              name
         FROM demotable
       )
 GROUP BY group_id

There are many way to do the string aggregation, but the easiest is a user defined function. Try this for a way that does not require a function. As a note, there is no simple way without the function.

This is the shortest route without a custom function: (it uses the ROW_NUMBER() and SYS_CONNECT_BY_PATH functions )

SELECT questionid,
       LTRIM(MAX(SYS_CONNECT_BY_PATH(elementid,','))
       KEEP (DENSE_RANK LAST ORDER BY curr),',') AS elements
FROM   (SELECT questionid,
               elementid,
               ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) AS curr,
               ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) -1 AS prev
        FROM   emp)
GROUP BY questionid
CONNECT BY prev = PRIOR curr AND questionid = PRIOR questionid
START WITH curr = 1;

Doesn't look like you are using the correct overload of ActionLink. Try this:-

<%=Html.ActionLink("Modify Villa", "Modify", new {id = "1"})%>

This assumes your view is under the /Views/Villa folder. If not then I suspect you need:-

<%=Html.ActionLink("Modify Villa", "Modify", "Villa", new {id = "1"}, null)%>

if (Data_Array["XML_File"] != "") String xmlfile = Data_Array["XML_File"];

public class BinaryConverter {

    public static String binaryConverter(int number) {
        String binary = "";
        if (number == 1){
            binary = "1";
            System.out.print(binary);
            return binary;
        }
        if (number == 0){
            binary = "0";
            System.out.print(binary);
            return binary;
        }
        if (number > 1) {
            String i = Integer.toString(number % 2);

            binary = binary + i;
            binaryConverter(number/2);
        }
        System.out.print(binary);
        return binary;
    }
}

Many "correct" answers here but I'll add one more since I think some details are left out of several. The OP asked for 90 degree rotation but I'll change to 45 degrees because when you use an angle that isn't zero or 90, you should change the horizontal alignment as well; otherwise your labels will be off-center and a bit misleading (and I'm guessing many people who come here want to rotate axes to something other than 90).

Easiest / Least Code

Option 1

plt.xticks(rotation=45, ha='right')

As mentioned previously, that may not be desirable if you'd rather take the Object Oriented approach.

Option 2

Another fast way (it's intended for date objects but seems to work on any label; doubt this is recommended though):

fig.autofmt_xdate(rotation=45)

fig you would usually get from:

• fig = plt.figure()
• fig, ax = plt.subplots()
• fig = ax.figure

Object-Oriented / Dealing directly with ax

Option 3a

If you have the list of labels:

labels = ['One', 'Two', 'Three']
ax.set_xticklabels(labels, rotation=45, ha='right')

Option 3b

If you want to get the list of labels from the current plot:

# Unfortunately you need to draw your figure first to assign the labels,
# otherwise get_xticklabels() will return empty strings.
plt.draw()
ax.set_xticklabels(ax.get_xticklabels(), rotation=45, ha='right')

Option 4

Similar to above, but loop through manually instead.

for label in ax.get_xticklabels():
  label.set_rotation(45)
  label.set_ha('right')

Option 5

We still use pyplot (as plt) here but it's object-oriented because we're changing the property of a specific ax object.

plt.setp(ax.get_xticklabels(), rotation=45, ha='right')

Option 6

This option is simple, but AFAIK you can't set label horizontal align this way so another option might be better if your angle is not 90.

ax.tick_params(axis='x', labelrotation=45)

Edit: There's discussion of this exact "bug" and a fix is potentially slated for v3.2.0: https://github.com/matplotlib/matplotlib/issues/13774

Noting klaisbyskov's comment about your key length needing to be gigabytes in size, and assuming that you do in fact need this, then I think your only options are:

1. use a hash of the key value
   • Create a column on nchar(40) (for a sha1 hash, for example),
   • put a unique key on the hash column.
   • generate the hash when saving or updating the record
2. triggers to query the table for an existing match on insert or update.

Hashing comes with the caveat that one day, you might get a collision.

Triggers will scan the entire table.

Over to you...

JS only - no need for jquery

Simply create an input element and trigger the click.

var input = document.createElement('input');
input.type = 'file';
input.click();

This is the most basic, pop a select-a-file dialog, but its no use for anything without handling the selected file...

Handling the files

Adding an onchange event to the newly created input would allow us to do stuff once the user has selected the file.

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 
   var file = e.target.files[0]; 
}

input.click();

At the moment we have the file variable storing various information :

file.name // the file's name including extension
file.size // the size in bytes
file.type // file type ex. 'application/pdf'

Great!

But, what if we need the content of the file?

In order to get to the actual content of the file, for various reasons. place an image, load into canvas, create a window with Base64 data url, etc. we would need to use the FileReader API

We would create an instance of the FileReader, and load our user selected file reference to it.

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 

   // getting a hold of the file reference
   var file = e.target.files[0]; 

   // setting up the reader
   var reader = new FileReader();
   reader.readAsText(file,'UTF-8');

   // here we tell the reader what to do when it's done reading...
   reader.onload = readerEvent => {
      var content = readerEvent.target.result; // this is the content!
      console.log( content );
   }

}

input.click();

Trying pasting the above code into your devtool's console window, it should produce a select-a-file dialog, after selecting the file, the console should now print the contents of the file.

Example - "Stackoverflow's new background image!"

Let's try to create a file select dialog to change stackoverflows background image to something more spicy...

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 

   // getting a hold of the file reference
   var file = e.target.files[0]; 

   // setting up the reader
   var reader = new FileReader();
   reader.readAsDataURL(file); // this is reading as data url

   // here we tell the reader what to do when it's done reading...
   reader.onload = readerEvent => {
      var content = readerEvent.target.result; // this is the content!
      document.querySelector('#content').style.backgroundImage = 'url('+ content +')';
   }

}

input.click();

open devtools, and paste the above code into console window, this should pop a select-a-file dialog, upon selecting an image, stackoverflows content box background should change to the image selected.

Cheers!

I found a way to display the Document Location module in Office 2010.

File -> Options -> Quick Access Toolbar

From the Choose commands list select All Commands find "Document Location" press the "Add>>" button.

press OK.

Viola, the file path is at the top of your 2010 office document.

That error arises when you try to encode a non-unicode string: it tries to decode it, assuming it's in plain ASCII. There are two possibilities:

1. You're encoding it to a bytestring, but because you've used codecs.open, the write method expects a unicode object. So you encode it, and it tries to decode it again. Try: f.write(all_html) instead.
2. all_html is not, in fact, a unicode object. When you do .encode(...), it first tries to decode it.

Combined a few answers here to create a SP that returns the parts of the string.

drop procedure if exists SplitStr;
DELIMITER ;;
CREATE PROCEDURE `SplitStr`(IN Str VARCHAR(2000), IN Delim VARCHAR(1))

        create temporary table if not exists tb_split

You have just to enter:

First a IBOutlet:

@IBOutlet var appsTableView : UITableView

Then in a Action func:

self.appsTableView.reloadData()

You can use convert from hablar to change a column of the data frame quickly.

library(tidyverse)
library(hablar)

x <- tibble(var = c(1.34, 4.45, 6.98))

x %>% 
  convert(int(var))

gives you:

# A tibble: 3 x 1
    var
  <int>
1     1
2     4
3     6

Declare in your Model with

  [DataType(DataType.MultilineText)]
  public string urString { get; set; }

Then in .cshtml can make use of editor as below. you can make use of @cols and @rows for TextArea size

     @Html.EditorFor(model => model.urString, new { htmlAttributes = new { @class = "",@cols = 35, @rows = 3 } })

Thanks !

A bit of a hack, but this gives the effect of a multi-line select, puts in a gray bgcolor for your multi line, and if you select any of the gray text, it selects the first of the grouping. Kinda clever I'd say :) The first option also shows how you can put a title tag in for an option as well.

 function SelectFirst(SelVal) {_x000D_
   var arrSelVal = SelVal.split(",")_x000D_
   if (arrSelVal.length > 1) {_x000D_
     Valuetoselect = arrSelVal[0];_x000D_
     document.getElementById("select1").value = Valuetoselect;_x000D_
   }_x000D_
 }

<select name="select1" id="select1" onchange="SelectFirst(this.value)">_x000D_
  <option value="1" title="this is my long title for the yes option">Yes</option>_x000D_
  <option value="2">No</option>_x000D_
  <option value="2,1" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is my description for the no option</option>_x000D_
  <option value="2,2" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 2 for the no option</option>_x000D_
  <option value="3">Maybe</option>_x000D_
  <option value="3,1" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is my description for Maybe option</option>_x000D_
  <option value="3,2" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 2 for the Maybe option</option>_x000D_
  <option value="3,3" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 3 for the Maybe option</option>_x000D_
</select>

You can use LOG such as :

Log.e(String, String) (error)

Since no one mentioned I am adding on it, When you pass a object to a function in c++ the default copy constructor of the object is called if you dont have one which creates a clone of the object and then pass it to the method, so when you change the object values that will reflect on the copy of the object instead of the original object, that is the problem in c++, So if you make all the class attributes to be pointers, then the copy constructors will copy the addresses of the pointer attributes , so when the method invocations on the object which manipulates the values stored in pointer attributes addresses, the changes also reflect in the original object which is passed as a parameter, so this can behave same a Java but dont forget that all your class attributes must be pointers, also you should change the values of pointers, will be much clear with code explanation.

Class CPlusPlusJavaFunctionality {
    public:
       CPlusPlusJavaFunctionality(){
         attribute = new int;
         *attribute = value;
       }

       void setValue(int value){
           *attribute = value;
       }

       void getValue(){
          return *attribute;
       }

       ~ CPlusPlusJavaFuncitonality(){
          delete(attribute);
       }

    private:
       int *attribute;
}

void changeObjectAttribute(CPlusPlusJavaFunctionality obj, int value){
   int* prt = obj.attribute;
   *ptr = value;
}

int main(){

   CPlusPlusJavaFunctionality obj;

   obj.setValue(10);

   cout<< obj.getValue();  //output: 10

   changeObjectAttribute(obj, 15);

   cout<< obj.getValue();  //output: 15
}

But this is not good idea as you will be ending up writing lot of code involving with pointers, which are prone for memory leaks and do not forget to call destructors. And to avoid this c++ have copy constructors where you will create new memory when the objects containing pointers are passed to function arguments which will stop manipulating other objects data, Java does pass by value and value is reference, so it do not require copy constructors.

No.

From the cron man page:

...cron will then examine the modification time on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified

But if you just want to make sure its done anyway,

sudo service cron reload

or

/etc/init.d/cron reload

I didn't want to install a package just for that purpose so I ended up using this in my init.coffee:

spawn = require('child_process').spawn
atom.commands.add 'atom-text-editor', 'open-terminal', ->
  file = atom.workspace.getActiveTextEditor().getPath()
  dir = atom.project.getDirectoryForProjectPath(file).path
  spawn 'mate-terminal', ["--working-directory=#{dir}"], {
    detached: true
  }

With that, I could map ctrl-shift-t to the open-terminal command and it opens a mate-terminal.

Creating a dummy blank repositories.cfg works on Windows 7 as well. After waiting for a couple of minutes the installation finishes and you get the message on your cmd window -- done

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.

Tab as Enter: create a user control which inherits textbox, override the KeyPress method. If the user presses enter you can either call SendKeys.Send("{TAB}") or System.Windows.Forms.Control.SelectNextControl(). Note you can achieve the same using the KeyPress event.

Focus Entire text: Again, via override or events, target the GotFocus event and then call TextBox.Select method.

The second placeholder is for decimals.

The last placeholder is for thousands separator.

You should start with version 1, unless you know that the first version you "release" is incomplete in some way.

As to how you increment the versions, that's up to you, but use the major, minor, build numbering as a guide.

It's not necessary to have every version you commit to source control as another version - you'll soon have a very large version number indeed. You only need to increment the version number (in some way) when you release a new version to the outside world.

So If you make a major change move from version 1.0.0.0 to version 2.0.0.0 (you changed from WinForms to WPF for example). If you make a smaller change move from 1.0.0.0 to 1.1.0.0 (you added support for png files). If you make a minor change then go from 1.0.0.0 to 1.0.1.0 (you fixed some bugs).

If you really want to get detailed use the final number as the build number which would increment for every checkin/commit (but I think that's going too far).

With Spring Boot, I'm not entirely sure why this was necessary (I got the /error fallback even though @ResponseBody was defined on an @ExceptionHandler), but the following in itself did not work:

@ResponseBody
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(IllegalArgumentException.class)
public ErrorMessage handleIllegalArguments(HttpServletRequest httpServletRequest, IllegalArgumentException e) {
    log.error("Illegal arguments received.", e);
    ErrorMessage errorMessage = new ErrorMessage();
    errorMessage.code = 400;
    errorMessage.message = e.getMessage();
    return errorMessage;
}

It still threw an exception, apparently because no producible media types were defined as a request attribute:

// AbstractMessageConverterMethodProcessor
@SuppressWarnings("unchecked")
protected <T> void writeWithMessageConverters(T value, MethodParameter returnType,
        ServletServerHttpRequest inputMessage, ServletServerHttpResponse outputMessage)
        throws IOException, HttpMediaTypeNotAcceptableException, HttpMessageNotWritableException {

    Class<?> valueType = getReturnValueType(value, returnType);
    Type declaredType = getGenericType(returnType);
    HttpServletRequest request = inputMessage.getServletRequest();
    List<MediaType> requestedMediaTypes = getAcceptableMediaTypes(request);
    List<MediaType> producibleMediaTypes = getProducibleMediaTypes(request, valueType, declaredType);
if (value != null && producibleMediaTypes.isEmpty()) {
        throw new IllegalArgumentException("No converter found for return value of type: " + valueType);   // <-- throws
    }

// ....

@SuppressWarnings("unchecked")
protected List<MediaType> getProducibleMediaTypes(HttpServletRequest request, Class<?> valueClass, Type declaredType) {
    Set<MediaType> mediaTypes = (Set<MediaType>) request.getAttribute(HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE);
    if (!CollectionUtils.isEmpty(mediaTypes)) {
        return new ArrayList<MediaType>(mediaTypes);

So I added them.

@ResponseBody
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(IllegalArgumentException.class)
public ErrorMessage handleIllegalArguments(HttpServletRequest httpServletRequest, IllegalArgumentException e) {
    Set<MediaType> mediaTypes = new HashSet<>();
    mediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
    httpServletRequest.setAttribute(HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE, mediaTypes);
    log.error("Illegal arguments received.", e);
    ErrorMessage errorMessage = new ErrorMessage();
    errorMessage.code = 400;
    errorMessage.message = e.getMessage();
    return errorMessage;
}

And this got me through to have a "supported compatible media type", but then it still didn't work, because my ErrorMessage was faulty:

public class ErrorMessage {
    int code;

    String message;
}

JacksonMapper did not handle it as "convertable", so I had to add getters/setters, and I also added @JsonProperty annotation

public class ErrorMessage {
    @JsonProperty("code")
    private int code;

    @JsonProperty("message")
    private String message;

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

Then I received my message as intended

{"code":400,"message":"An \"url\" parameter must be defined."}

Looking at posted answers I think this code would be also an alternative for someone. Nobody above used .Shapes.AddPicture in their code, only .Pictures.Insert()

Dim myPic As Object
Dim picpath As String

picpath = "C:\Users\photo.jpg" 'example photo path

Set myPic = ws.Shapes.AddPicture(picpath, False, True, 20, 20, -1, -1)

With myPic
    .Width = 25
    .Height = 25
    .Top = xlApp.Cells(i, 20).Top 'according to variables from correct answer
    .Left = xlApp.Cells(i, 20).Left
    .LockAspectRatio = msoFalse
End With

I'm working in Excel 2013. Also realized that You need to fill all the parameters in .AddPicture, because of error "Argument not optional". Looking at this You may ask why I set Height and Width as -1, but that doesn't matter cause of those parameters are set underneath between With brackets.

Hope it may be also useful for someone :)

Ctrl + Shift + O (<-- an 'O' not a zero)

Note: This shortcut also removes unused imports.

Properties are used to encapsulate some data. You could use a plain field:

public string MyField

But this field can be accessed by all outside users of your class. People can insert illegal values or change the value in ways you didn't expect.

By using a property, you can encapsulate the way your data is accessed. C# has a nice syntax for turning a field into a property:

string MyProperty { get; set; }

This is called an auto-implemented property. When the need arises you can expand your property to:

string _myProperty;

public string MyProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

Now you can add code that validates the value in your setter:

set
{
    if (string.IsNullOrWhiteSpace(value))
        throw new ArgumentNullException();

    _myProperty = value;
}

Properties can also have different accessors for the getter and the setter:

public string MyProperty { get; private set; }

This way you create a property that can be read by everyone but can only be modified by the class itself.

You can also add a completely custom implementation for your getter:

public string MyProperty
{
    get
    {
        return DateTime.Now.Second.ToString();
    }
}

When C# compiles your auto-implemented property, it generates Intermediate Language (IL). In your IL you will see a get_MyProperty and set_MyProperty method. It also creates a backing field called <MyProperty>k_BackingField (normally this would be an illegal name in C# but in IL it's valid. This way you won't get any conflicts between generated types and your own code). However, you should use the official property syntax in C#. This creates a nicer experience in C# (for example with IntelliSense).

By convention, you shouldn't use properties for operations that take a long time.

Here I what I did to have an ImageButton which always have a width equals to its height (and avoid stupid empty margins in one direction...which I consider a as a bug of the SDK...):

I defined a SquareImageButton class which extends from ImageButton:

package com.myproject;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.ImageButton;

    public class SquareImageButton extends ImageButton {

        public SquareImageButton(Context context) {
        super(context);


        // TODO Auto-generated constructor stub
    }

    public SquareImageButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub

    }

    public SquareImageButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub

    }

    int squareDim = 1000000000;

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);


        int h = this.getMeasuredHeight();
        int w = this.getMeasuredWidth();
        int curSquareDim = Math.min(w, h);
        // Inside a viewholder or other grid element,
        // with dynamically added content that is not in the XML,
        // height may be 0.
        // In that case, use the other dimension.
        if (curSquareDim == 0)
            curSquareDim = Math.max(w, h);

        if(curSquareDim < squareDim)
        {
            squareDim = curSquareDim;
        }

        Log.d("MyApp", "h "+h+"w "+w+"squareDim "+squareDim);


        setMeasuredDimension(squareDim, squareDim);

    }

}

Here is my xml:

<com.myproject.SquareImageButton
            android:id="@+id/speakButton"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:scaleType="centerInside"
            android:src="@drawable/icon_rounded_no_shadow_144px"
            android:background="#00ff00"
            android:layout_alignTop="@+id/searchEditText"
            android:layout_alignBottom="@+id/searchEditText"
            android:layout_alignParentLeft="true"
           />

Works like a charm !

This seems to work:

$("#theSelect").change(function(){          
    var value = $("#theSelect option:selected").val();
    var theDiv = $(".is" + value);

    theDiv.slideDown().removeClass("hidden");
    //Add this...
    $("#theSelect option:selected").attr('disabled', 'disabled');
});


$("div a.remove").click(function () {     
    $(this).parent().slideUp(function() { $(this).addClass("hidden"); });
    //...and this.
    $("#theSelect option:disabled").removeAttr('disabled');
});

On a generic note, you can use a combination of ng-if and ng-style incorporate conditional changes with change in background image.

<span ng-if="selectedItem==item.id"
              ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_active.png)','background-size':'52px 57px','padding-top':'70px','background-repeat':'no-repeat','background-position': 'center'}"></span>
        <span ng-if="selectedItem!=item.id"
              ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_deactivated.png)','background-size':'52px 57px','padding-top':'70px','background-repeat':'no-repeat','background-position': 'center'}"></span>

The setCustomValidity let you change the default validation message.Here is a simple exmaple of how to use it.

var age  =  document.getElementById('age');
    age.form.onsubmit = function () {
    age.setCustomValidity("This is not a valid age.");
 };

PHP 5.5+

Starting PHP5.5+ you have array_column() available to you, which makes all of the below obsolete.

PHP 5.3+

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Solution by @phihag will work flawlessly in PHP starting from PHP 5.3.0, if you need support before that, you will need to copy that wp_list_pluck.

PHP < 5.3

In Wordpress there is a function called wp_list_pluck If you're using Wordpress that solves your problem.

If you're not using Wordpress, since the code is open source you can copy paste the code in your project (and rename the function to something you prefer, like array_pick). View source here

Maybe you forgot the await before returning your collection

The first question you need to ask is whether you really need the ID to be random. Sometime, sequential IDs are good enough.

Now, if you do need it to be random, we first note a generated sequence of numbers that contain no duplicates can not be called random. :p Now that we get that out of the way, the fastest way to do this is to have a Hashtable or HashMap containing all the IDs already generated. Whenever a new ID is generated, check it against the hashtable, re-generate if the ID already occurs. This will generally work well if the number of students is much less than the range of the IDs. If not, you're in deeper trouble as the probability of needing to regenerate an ID increases, P(generate new ID) = number_of_id_already_generated / number_of_all_possible_ids. In this case, check back the first paragraph (do you need the ID to be random?).

Hope this helps.

Use packaging.version.parse.

>>> from packaging import version
>>> version.parse("2.3.1") < version.parse("10.1.2")
True
>>> version.parse("1.3.a4") < version.parse("10.1.2")
True
>>> isinstance(version.parse("1.3.a4"), version.Version)
True
>>> isinstance(version.parse("1.3.xy123"), version.LegacyVersion)
True
>>> version.Version("1.3.xy123")
Traceback (most recent call last):
...
packaging.version.InvalidVersion: Invalid version: '1.3.xy123'

packaging.version.parse is a third-party utility but is used by setuptools (so you probably already have it installed) and is conformant to the current PEP 440; it will return a packaging.version.Version if the version is compliant and a packaging.version.LegacyVersion if not. The latter will always sort before valid versions.

Note: packaging has recently been vendored into setuptools.

An ancient alternative still used by a lot of software is distutils.version, built in but undocumented and conformant only to the superseded PEP 386;

>>> from distutils.version import LooseVersion, StrictVersion
>>> LooseVersion("2.3.1") < LooseVersion("10.1.2")
True
>>> StrictVersion("2.3.1") < StrictVersion("10.1.2")
True
>>> StrictVersion("1.3.a4")
Traceback (most recent call last):
...
ValueError: invalid version number '1.3.a4'

As you can see it sees valid PEP 440 versions as “not strict” and therefore doesn’t match modern Python’s notion of what a valid version is.

As distutils.version is undocumented, here's the relevant docstrings.

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

This is worked for me

$('<div>We failed</div>')
    .dialog(
    {
        title: 'Error',
        close: function(event, ui)
        {
            $(this).dialog("close");
            $(this).remove();
        }
    });

Cheers!

For docker on macOS, you can use docker-time-sync-agent. It works for me.

I am writing this because the accepted answer is pretty old, it needs a refresher.

So this is how I would integrate Ajax with Django in 2019 :) And lets take a real example of when we would need Ajax :-

Lets say I have a model with registered usernames and with the help of Ajax I wanna know if a given username exists.

html:

<p id="response_msg"></p> 
<form id="username_exists_form" method='GET'>
      Name: <input type="username" name="username" />
      <button type='submit'> Check </button>           
</form>   

ajax:

$('#username_exists_form').on('submit',function(e){
    e.preventDefault();
    var username = $(this).find('input').val();
    $.get('/exists/',
          {'username': username},   
          function(response){ $('#response_msg').text(response.msg); }
    );
}); 

urls.py:

from django.contrib import admin
from django.urls import path
from . import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('exists/', views.username_exists, name='exists'),
]

views.py:

def username_exists(request):
    data = {'msg':''}   
    if request.method == 'GET':
        username = request.GET.get('username').lower()
        exists = Usernames.objects.filter(name=username).exists()
        if exists:
            data['msg'] = username + ' already exists.'
        else:
            data['msg'] = username + ' does not exists.'
    return JsonResponse(data)

Also render_to_response which is deprecated and has been replaced by render and from Django 1.7 onwards instead of HttpResponse we use JsonResponse for ajax response. Because it comes with a JSON encoder, so you don’t need to serialize the data before returning the response object but HttpResponse is not deprecated.

Depending on the hibernate flush mode that you are using (AUTO is the default) save may or may not write your changes to the DB straight away. When you call saveAndFlush you are enforcing the synchronization of your model state with the DB.

If you use flush mode AUTO and you are using your application to first save and then select the data again, you will not see a difference in bahvior between save() and saveAndFlush() because the select triggers a flush first. See the documention.

Honestly, I hate all the solutions I've seen so far, and I'll tell you why: They just don't seem to ever align it right...so here's what I usually do:

I know what pixel values each div and their respective margins hold...so I do the following.

I'll create a wrapper div that has an absolute position and a left value of 50%...so this div now starts in the middle of the screen, and then I subtract half of all the content of the div's width...and I get BEAUTIFULLY scaling content...and I think this works across all browsers, too. Try it for yourself (this example assumes all content on your site is wrapped in a div tag that uses this wrapper class and all content in it is 200px in width):

.wrapper {
    position: absolute;
    left: 50%;
    margin-left: -100px;
}

EDIT: I forgot to add...you may also want to set width: 0px; on this wrapper div for some browsers to not show the scrollbars, and then you may use absolute positioning for all inner divs.

This also works AMAZING for vertically aligning your content as well using top: 50% and margin-top. Cheers!

LR is link register used to hold the return address for a function call.

SP is stack pointer. The stack is generally used to hold "automatic" variables and context/parameters across function calls. Conceptually you can think of the "stack" as a place where you "pile" your data. You keep "stacking" one piece of data over the other and the stack pointer tells you how "high" your "stack" of data is. You can remove data from the "top" of the "stack" and make it shorter.

From the ARM architecture reference:

SP, the Stack Pointer

Register R13 is used as a pointer to the active stack.

In Thumb code, most instructions cannot access SP. The only instructions that can access SP are those designed to use SP as a stack pointer. The use of SP for any purpose other than as a stack pointer is deprecated. Note Using SP for any purpose other than as a stack pointer is likely to break the requirements of operating systems, debuggers, and other software systems, causing them to malfunction.

LR, the Link Register

Register R14 is used to store the return address from a subroutine. At other times, LR can be used for other purposes.

When a BL or BLX instruction performs a subroutine call, LR is set to the subroutine return address. To perform a subroutine return, copy LR back to the program counter. This is typically done in one of two ways, after entering the subroutine with a BL or BLX instruction:

• Return with a BX LR instruction.

• On subroutine entry, store LR to the stack with an instruction of the form: PUSH {,LR} and use a matching instruction to return: POP {,PC} ...

This link gives an example of a trivial subroutine.

Here is an example of how registers are saved on the stack prior to a call and then popped back to restore their content.

I am not sure it would read better but you could do the following:

while any((not condition1, not condition2, val == -1)):
    val,something1,something2 = getstuff()

    if something1==10:
        condition1 = True

    if something2==20:
        condition2 = True

You can do this in Java too. And no, it's not a good practice. :)

(And use the === in Javascript for typed equality. Read Crockford's The Good Parts book on JS.)

Relying on compiler optimizations is fragile. The benchmarks linked in the accepted answer and numbers given by Antoine-tran are not to be trusted. Andrew Hare makes the mistake of including a call to repr in his methods. That slows all the methods equally but obscures the real penalty in constructing the string.

Use join. It's very fast and more robust.

Rather than use Ajax / XMLHttpRequest / $http to invoke your WebApi method, use an html form. That way the browser saves the file using the filename and content type information in the response headers, and you don't need to work around javascript's limitations on file handling. You might also use a GET method rather than a POST as the method returns data. Here's an example form:

<form name="export" action="/MyController/Export" method="get" novalidate>
    <input name="id" type="id" ng-model="id" placeholder="ID" />
    <input name="fileName" type="text" ng-model="filename" placeholder="file name" required />
    <span class="error" ng-show="export.fileName.$error.required">Filename is required!</span>
    <button type="submit" ng-disabled="export.$invalid">Export</button>
</form>

To see a list of available simulators via terminal, type:

$ xcrun simctl list

This will return a list of devices e.g., iPhone 11 Pro Max (6A7BEA2F-95E4-4A34-98C1-01C9906DCBDE) (Shutdown). The long string of characters is the device UUID.

To start the device via terminal, simply type:

$ xcrun simctl boot 6A7BEA2F-95E4-4A34-98C1-01C9906DCBDE

To shut it down, type:

$ xcrun simctl shutdown 6A7BEA2F-95E4-4A34-98C1-01C9906DCBDE

Alternatively, to launch a simulator:

open -a simulator

If you want to use the new current standard, you can do so:

sub.emplace_back ("Math", 70, 0);

or

sub.push_back ({"Math", 70, 0});

If you don't want to repeat the list twice (as per @J W's answer), then put the updates in a table variable and use a JOIN in the UPDATE:

declare @ToDo table (FromName varchar(10), ToName varchar(10))
insert into @ToDo(FromName,ToName) values
 ('AAA','BBB'),
 ('CCC','DDD'),
 ('EEE','FFF')

update ts set LastName = ToName
from dbo.TestStudents ts
       inner join
     @ToDo t

I was using nano, and it took me a long time to figure out this error. My problem was I was using the wrong port. I had port 5948 instead of 5984.

get sock opt may be somewhat useful, however, another way would to have a signal handler installed for SIGPIPE. Basically whenever you the socket connection breaks, the kernel will send a SIGPIPE signal to the process and then you can do the needful. But this still does not provide the solution for knowing the status of the connection. hope this helps.

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

Using TLS 1.2 solved this error.
You can force your application using TLS 1.2 with this (make sure to execute it before calling your service):

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 

Another solution :
Enable strong cryptography in your local machine or server in order to use TLS1.2 because by default it is disabled so only TLS1.0 is used.
To enable strong cryptography , execute these commande in PowerShell with admin privileges :

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord 

You need to reboot your computer for these changes to take effect.

_animals.OrderByDescending(a => a.<what_is_here_?>);

If animals would be a list of object Animal, you could use a property to order the list.

public class Animal
{
    public int ID {get; set;}
    public string Name {get; set;}
    ...
}

ObservableCollection<Animal> animals = ...
animals = animals.OrderByDescending(a => a.Name);

Unfortunately I can't comment with my newbie reputation, but I have a solution for the issue of the screen going blank, or at least this is what worked for me. Instead of setting the wrapper class inside of the errorPlacement function, set it immediately when you're setting the wrapper type.

$('#myForm').validate({
    errorElement: "div",
    wrapper: "div class=\"message\"",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertBefore(element);
        //error.addClass('message');  // add a class to the wrapper
        error.css('position', 'absolute');
        error.css('left', offset.left + element.outerWidth() + 5);
        error.css('top', offset.top - 3);
    }

});

I'm assuming doing it this way allows the validator to know which div elements to remove, instead of all of them. Worked for me but I'm not entirely sure why, so if someone could elaborate that might help others out a ton.

You can also apply the default 'text' classes available from bootstrap itself

 <h1 class='text-info'>Hey... I'm blue</h1>

You can use Google Cloud Messaging or GCM, it's free and easy to use. Also you can use third party push servers like PushWoosh which gives you more flexibility

My problem: Find indexes of list.

L = makelist() # Returns a list of different objects

When buffer size gets full. There are several options you can try:

1) Increase the size of the DBMS_OUTPUT buffer to 1,000,000

2) Try filtering the data written to the buffer - possibly there is a loop that writes to DBMS_OUTPUT and you do not need this data.

3) Call ENABLE at various checkpoints within your code. Each call will clear the buffer.

DBMS_OUTPUT.ENABLE(NULL) will default to 20000 for backwards compatibility Oracle documentation on dbms_output

You can also create your custom output display.something like below snippets

create or replace procedure cust_output(input_string in varchar2 )
is 

   out_string_in long default in_string; 
   string_lenth number; 
   loop_count number default 0; 

begin 

   str_len := length(out_string_in);

   while loop_count < str_len
   loop 
      dbms_output.put_line( substr( out_string_in, loop_count +1, 255 ) ); 
      loop_count := loop_count +255; 
   end loop; 
end;

For files changed between a given SHA and your current commit:

git diff --name-only <starting SHA> HEAD

or if you want to include changed-but-not-yet-committed files:

git diff --name-only <starting SHA>

More generally, the following syntax will always tell you which files changed between two commits (specified by their SHAs or other names):

git diff --name-only <commit1> <commit2>

In general, these answer the question: How to change your user settings file? But the question I wanted answered was how to change my local maven repository location. The answer is that you have to edit settings.xml. If the file does not exist, you have to create it. You set or change the location of the file at Window > Preferences > Maven > User Settings. It's the User Settings entry at

It's the second file input; the first with information in it.

If it's not clear, [redacted] should be replaced with the local file path to your .m2 folder.

If you click the "open file" link, it opens the settings.xml file for editing in Eclipse.

If you have no settings.xml file yet, the following will set the local repository to the Windows 10 default value for a user named mdfst13:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                              https://maven.apache.org/xsd/settings-1.0.0.xsd">

  <localRepository>C:\Users\mdfst13\.m2\repository</localRepository>
</settings>

You should set this to a value appropriate to your system. I haven't tested it, but I suspect that in Linux, the default value would be /home/mdfst13/.m2/repository. And of course, you probably don't want to set it to the default value. If you are reading this, you probably want to set it to some other value. You could just delete it if you wanted the default.

Credit to this comment by @ejaenv for the name of the element in the settings file: <localRepository>. See Maven — Settings Reference for more information.

Credit to @Ajinkya's answer for specifying the location of the User Settings value in Eclipse Photon.

If you already have a settings.xml file, you should merge this into your existing file. I.e. <settings and <localRepository> should only appear once in the file, and you probably want to retain any settings already there. Or to say that another way, edit any existing local repository entry if it exists or just add that line to the file if it doesn't.

I had to restart Eclipse for it to load data into the new repository. Neither "Update Settings" nor "Reindex" was sufficient.

Let's say you have:

<a></a>

<(.*)> would match a></a where as <(.*?)> would match a. The latter stops after the first match of >. It checks for one or 0 matches of .* followed by the next expression.

The first expression <(.*)> doesn't stop when matching the first >. It will continue until the last match of >.

The main article in the Angular2 documentation on this subject is :

https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#parent-to-child

It covers the following:

• Pass data from parent to child with input binding

• Intercept input property changes with a setter

• Intercept input property changes with ngOnChanges

• Parent listens for child event

• Parent interacts with child via a local variable

• Parent calls a ViewChild

• Parent and children communicate via a service

In interface Builder set table view separator "None"

and those separator lines which are shown after the last cell can be remove by following approach. Best approach is to assign Empty View to tableView FooterView in viewDidLoad

self.tableView.tableFooterView = UIView()

Use ISNULL to overcome it.

Example:

SELECT (ISNULL(field1, '') + '' + ISNULL(field2, '')+ '' + ISNULL(field3, '')) FROM table1

This will then replace your NULL content with an empty string which will preserve the concatentation operation from evaluating as an overall NULL result.

In general compact is preferable to repairDatabase. But one advantage of repair over compact is you can issue repair to the whole cluster. compact you have to log into each shard, which is kind of annoying.

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

I would also recommend Ilmbase, which is part of OpenEXR. It's a good set of templated 2,3,4-vector and matrix routines.

It is a code style convention; it indicates that a method returns a boolean value.

The question mark is a valid character at the end of a method name.

I am Administrator and some script placed "Deny" permission on my name on all files and subfolders in a directory. Executing the icacls "D:\test" /grant John:(OI)(CI)F /T command did not work, because it seemed it did not remove the "Deny" right from my name from this list.

The only thing that worked for me is resetting all permissions with the icacls "D:\test" /reset /T command.

The language attribute has been deprecated for a long time, and should not be used.

When W3C was working on HTML5, they discovered all browsers have "text/javascript" as the default script type, so they standardized it to be the default value. Hence, you don't need type either.

For pages in XHTML 1.0 or HTML 4.01 omitting type is considered invalid. Try validating the following:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<script src="http://example.com/test.js"></script>
</head>
<body/>
</html>

You will be informed of the following error:

Line 4, Column 41: required attribute "type" not specified

So if you're a fan of standards, use it. It should have no practical effect, but, when in doubt, may as well go by the spec.

All presented answers assume that the byte array contains data in a known file format representation, like: gif, png or jpg. But i recently had a problem trying to convert byte[]s, containing linearized BGRA information, efficiently into Image objects. The following code solves it using a Bitmap object.

using System.Drawing;
using System.Drawing.Imaging;
using System.Runtime.InteropServices;
public static class Extensions
{
    public static Image ImageFromRawBgraArray(
        this byte[] arr, int width, int height)
    {
        var output = new Bitmap(width, height);
        var rect = new Rectangle(0, 0, width, height);
        var bmpData = output.LockBits(rect, 
            ImageLockMode.ReadWrite, output.PixelFormat);
        var ptr = bmpData.Scan0;
        Marshal.Copy(arr, 0, ptr, arr.Length);
        output.UnlockBits(bmpData);
        return output;
    }
}

This is a slightly variation of a solution which was posted on this site.

You can try creating a css for your font with font-face (like explained here)

Step #1

Create a css file with font face and place it somewhere, like in assets/fonts

customfont.css

@font-face {
    font-family: YourFontFamily;
    src: url("/assets/font/yourFont.otf") format("truetype");
}

Step #2

Add the css to your .angular-cli.json in the styles config

"styles":[
 //...your other styles
 "assets/fonts/customFonts.css"
 ]

Do not forget to restart ng serve after doing this

Step #3

Use the font in your code

For me, the node binary is in PATH and I can run it from the terminal (iTerm or Terminal), and the Terminal apps are set to use zsh

If you are on a Mac, with iTerm and Zsh, please use the following VSCode settings for Node to work.

After this change, you can get rid of this line from your launch.json config file. (the debug settings in VSCode)

    "runtimeExecutable": "/usr/local/bin/node"

If this doesn't work, make sure you choose the default shell as zsh. To do this,

• Open the command palette using Cmd+Shift+P

• Look for the Terminal: Select Default Shell command

• Select zsh from the options

After reading every answer and trying them, none of them helped me. What I found while searching elsewhere is that you can create a custom attribute that you can then add to your controller. It overwrites the EnableCors ones and add the whitelisted domains in it.

This solution is working well because it lets you have the whitelisted domains in the webconfig (appsettings) instead of harcoding them in the EnableCors attribute on your controller.

 [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false)]
public class EnableCorsByAppSettingAttribute : Attribute, ICorsPolicyProvider
{
    const string defaultKey = "whiteListDomainCors";
    private readonly string rawOrigins;
    private CorsPolicy corsPolicy;

    /// <summary>
    /// By default uses "cors:AllowedOrigins" AppSetting key
    /// </summary>
    public EnableCorsByAppSettingAttribute()
        : this(defaultKey) // Use default AppSetting key
    {
    }

    /// <summary>

    /// <param name="appSettingKey">AppSetting key that defines valid origins</param>
    public EnableCorsByAppSettingAttribute(string appSettingKey)
    {
        // Collect comma separated origins
        this.rawOrigins = AppSettings.whiteListDomainCors;
        this.BuildCorsPolicy();
    }

    /// <summary>

    private void BuildCorsPolicy()
    {
        bool allowAnyHeader = String.IsNullOrEmpty(this.Headers) || this.Headers == "*";
        bool allowAnyMethod = String.IsNullOrEmpty(this.Methods) || this.Methods == "*";

        this.corsPolicy = new CorsPolicy
        {
            AllowAnyHeader = allowAnyHeader,
            AllowAnyMethod = allowAnyMethod,
        };

        // Add origins from app setting value
        this.corsPolicy.Origins.AddCommaSeperatedValues(this.rawOrigins);
        this.corsPolicy.Headers.AddCommaSeperatedValues(this.Headers);
        this.corsPolicy.Methods.AddCommaSeperatedValues(this.Methods);
    }

    public string Headers { get; set; }
    public string Methods { get; set; }

    public Task<CorsPolicy> GetCorsPolicyAsync(HttpRequestMessage request,
                                               CancellationToken cancellationToken)
    {
        return Task.FromResult(this.corsPolicy);
    }

    {
        if (current == null)
        {
            return;
        }

        var paths = new List<string>(AppSettings.whiteListDomainCors.Split(new char[] { ',' }));
        foreach (var value in paths)
        {
            current.Add(value);
        }
    }
}

I found this guide online and it worked like a charm :

I thought i'd drop that here for anyone in need.

Before you can add files in an unversioned directory, you have to add the directory itself to the versioning:

svn add directory_name

will add the directory directory_name and all sub-directories: http://svnbook.red-bean.com/en/1.8/svn.ref.svn.c.add.html

One way is to loop through the keys of the dictionary, which I recommend:

foreach(int key in sp.Keys)
    dynamic value = sp[key];

Another way, is to loop through the dictionary as a sequence of pairs:

foreach(KeyValuePair<int, dynamic> pair in sp)
{
    int key = pair.Key;
    dynamic value = pair.Value;
}

I recommend the first approach, because you can have more control over the order of items retrieved if you decorate the Keys property with proper LINQ statements, e.g., sp.Keys.OrderBy(x => x) helps you retrieve the items in ascending order of the key. Note that Dictionary uses a hash table data structure internally, therefore if you use the second method the order of items is not easily predictable.

Update (01 Dec 2016): replaced vars with actual types to make the answer more clear.

Here is slightly modified version. Changes are noted as code commentary.

BEGIN TRANSACTION

declare @cnt int
declare @test nvarchar(128)
-- variable to hold table name
declare @tableName nvarchar(255)
declare @cmd nvarchar(500) 
-- local means the cursor name is private to this code
-- fast_forward enables some speed optimizations
declare Tests cursor local fast_forward for
 SELECT COLUMN_NAME, TABLE_NAME
   FROM INFORMATION_SCHEMA.COLUMNS 
  WHERE COLUMN_NAME LIKE 'pct%' 
    AND TABLE_NAME LIKE 'TestData%'

open Tests
-- Instead of fetching twice, I rather set up no-exit loop
while 1 = 1
BEGIN
  -- And then fetch
  fetch next from Tests into @test, @tableName
  -- And then, if no row is fetched, exit the loop
  if @@fetch_status <> 0
  begin
     break
  end
  -- Quotename is needed if you ever use special characters
  -- in table/column names. Spaces, reserved words etc.
  -- Other changes add apostrophes at right places.
  set @cmd = N'exec sp_rename ''' 
           + quotename(@tableName) 
           + '.' 
           + quotename(@test) 
           + N''',''' 
           + RIGHT(@test,LEN(@test)-3) 
           + '_Pct''' 
           + N', ''column''' 

  print @cmd

  EXEC sp_executeSQL @cmd
END

close Tests 
deallocate Tests

ROLLBACK TRANSACTION
--COMMIT TRANSACTION

Officially it's Ctrl+F11 & Ctrl+F12 or KEYPAD 7 & KEYPAD 9.

In practise it's a bit quirky.

1. Specifically it's Left Ctrl+F11 and Left Ctrl+F12 to switch to previous orientation and next orientation respectively.

2. You have to release Ctrl before you can rotate again.

3. KEYPAD 7 and KEYPAD 9 only work with Num Lock OFF (so they're acting as Home & PageUp rather than 7 & 9).

4. The only orientations are vertically upright and rotated one quarter-turn anti-clockwise.

Maybe a bit too much info for such a simple question, but it drove me half-mad finding this out.

Note: This was tested on Android SDK R16 and a very old keyboard, modern keyboards may behave differently.

Also from Eclipse you can use DDMS which makes it really easy.

Just make sure your emulator is running, and then switch to DDMS perspective in Eclipse. You'll have full access to the File Explorer which will allow you to go in and easily delete the entire database.

You need to specify the format it already has, in order to parse it:

$InvoiceDate = [datetime]::ParseExact($invoice, "dd-MMM-yy", $null)

Now you can output it in the format you need:

$InvoiceDate.ToString('yyyy-MM-dd')

or

'{0:yyyy-MM-dd}' -f $InvoiceDate

Try this:

Update TableB Set
  Code = Coalesce(
    (Select Max(Value)
    From TableA 
    Where Id = b.Id), 123)
From TableB b

Here is a TryParse extension method based on Habib's answer:

public static bool TryParse(this string strInput, out JToken output)
{
    if (String.IsNullOrWhiteSpace(strInput))
    {
        output = null;
        return false;
    }
    strInput = strInput.Trim();
    if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
        (strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
    {
        try
        {
            output = JToken.Parse(strInput);
            return true;
        }
        catch (JsonReaderException jex)
        {
            //Exception in parsing json
            //optional: LogError(jex);
            output = null;
            return false;
        }
        catch (Exception ex) //some other exception
        {
            //optional: LogError(ex);
            output = null;
            return false;
        }
    }
    else
    {
        output = null;
        return false;
    }
}

Usage:

JToken jToken;
if (strJson.TryParse(out jToken))
{
    // work with jToken
}
else
{
    // not valid json
}

This way you can create Observable from data, in my case I need to maintain shopping cart:

service.ts

export class OrderService {
    cartItems: BehaviorSubject<Array<any>> = new BehaviorSubject([]);
    cartItems$ = this.cartItems.asObservable();

    // I need to maintain cart, so add items in cart

    addCartData(data) {
        const currentValue = this.cartItems.value; // get current items in cart
        const updatedValue = [...currentValue, data]; // push new item in cart

        if(updatedValue.length) {
          this.cartItems.next(updatedValue); // notify to all subscribers
        }
      }
}

Component.ts

export class CartViewComponent implements OnInit {
    cartProductList: any = [];
    constructor(
        private order: OrderService
    ) { }

    ngOnInit() {
        this.order.cartItems$.subscribe(items => {
            this.cartProductList = items;
        });
    }
}

In controller:

function innerItem($scope, $element){
    var jQueryInnerItem = $($element); 
}

You should also keep in mind that when using like, some sql flavors will ignore indexes, and that will kill performance. This is especially true if you don't use the "starts with" pattern like your example.

You should really look at the execution plan for the query and see what it's doing, guess as little as possible.

This being said, the "starts with" pattern can and is optimized in sql server. It will use the table index. EF 4.0 switched to like for StartsWith for this very reason.

For those looking for a one-liner:

grep xyz abc.txt | while read -r line; do echo "Processing $line"; done

D:\learn\Node.js\node app.js
module.js:549
    throw err;
    ^

Error: Cannot find module 'body-parser'

Sometimes version not match with package.json Fixed the problem by checking the package.json then use the following commands: npm install [email protected] it resolved for me.

Although its too late to answer this question, but still for those guys who came here to see the solution of same problem just like me and didn't get a satisfactory answer on this page, The reason is that you don't have your file in the form of .rb extension. You most probably have it in simple text mode. Let me elaborate. Binding up the whole solution on the page, here you go (assuming you filename is abc.rb or at least you created abc):

Type in terminal window:

cd ~/to/the/program/location
ruby abc.rb

and you are done

If the following error occurs

ruby: No such file or directory -- abc.rb (LoadError)

Then go to the directory in which you have the abc file, rename it as abc.rb Close gedit and reopen the file abc.rb. Apply the same set of commands and success!

short, sweet and you don't even need redirection :-)

perl -p -i -e 'tr/A-Z/a-z/' file

Note, until now posted solutions only work for png and jpg!

If you want it even easier without importing further libraries or you want to display an animated or not animated GIF File in your Ipython Notebook. Transform the line where you want to display it to markdown and use this nice short hack!

![alt text](test.gif "Title")

The following answer could be helpful for the first part of your question:

Django: How can I call a view function from template?

 img {
     display: block;
     margin-left: auto;
   }

Also, if you are running in most UNIX & Linux systems you can temporarily increase the stack size by the following command:

ulimit -s unlimited

But be careful, memory is a limited resource and with great power come great responsibilities :)

Add this code into the css file:

input {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}

This will help.

You can try below code will preserve any white-space and new lines in your text.

$str = "
put returns between paragraphs

for linebreak add 2 spaces at end

";

echo preg_replace( "/\r|\n/", "", $str );

Here's another case where raw types will bite you:

public class StrangeClass<T> {
  @SuppressWarnings("unchecked")
  public <X> X getSomethingElse() {
    return (X)"Testing something else!";
  }

  public static void main(String[] args) {
    final StrangeClass<String> withGeneric    = new StrangeClass<>();
    final StrangeClass         withoutGeneric = new StrangeClass();
    final String               value1,
                               value2;

    // Compiles
    value1 = withGeneric.getSomethingElse();

    // Produces compile error:
    // incompatible types: java.lang.Object cannot be converted to java.lang.String
    value2 = withoutGeneric.getSomethingElse();
  }
}

This is counter-intuitive because you'd expect the raw type to only affect methods bound to the class type parameter, but it actually also affects generic methods with their own type parameters.

As was mentioned in the accepted answer, you lose all support for generics within the code of the raw type. Every type parameter is converted to its erasure (which in the above example is just Object).

Crash page?

(It happens when MySQL has to query large rows. By default, memory_limit is set to small, which was safer for the hardware.)

You can check your system existing memory status, before increasing php.ini:

# free -m
             total       used       free     shared    buffers     cached
Mem:         64457      63791        666          0       1118      18273
-/+ buffers/cache:      44398      20058
Swap:         1021          0       1021

Here I have increased it as in the following and then do service httpd restart to fix the crash page issue.

# grep memory_limit /etc/php.ini
memory_limit = 512M

The other answers are all good. For Xilinx FPGA designs, it is best not to use global reset lines, and use initial blocks for reset conditions for most logic. Here is the white paper from Ken Chapman (Xilinx FPGA guru)

http://japan.xilinx.com/support/documentation/white_papers/wp272.pdf

        Object AccountObject = _dbContext.Accounts
                                   .Join(_dbContext.Users, acc => acc.AccountId, usr => usr.AccountId, (acc, usr) => new { acc, usr })
                                   .Where(x => x.usr.EmailAddress == key1)
                                   .Where(x => x.usr.Hash == key2)
                                   .Select(x => new { AccountId = x.acc.AccountId, Name = x.acc.Name })
                                   .SingleOrDefault();

From a performance point of view, in python3.X

• [i[0] for i in a] and list(zip(*a))[0] are equivalent
• they are faster than list(map(operator.itemgetter(0), a))

Code

import timeit


iterations = 100000
init_time = timeit.timeit('''a = [(i, u'abc') for i in range(1000)]''', number=iterations)/iterations
print(timeit.timeit('''a = [(i, u'abc') for i in range(1000)]\nb = [i[0] for i in a]''', number=iterations)/iterations - init_time)
print(timeit.timeit('''a = [(i, u'abc') for i in range(1000)]\nb = list(zip(*a))[0]''', number=iterations)/iterations - init_time)

output

3.422205176000717e-05

Use onClick with one of the following:

window.location.reload(), i.e.:

<button onClick="window.location.reload();">Refresh Page</button>

Or history.go(0), i.e.:

<button onClick="history.go(0);">Refresh Page</button>

Or window.location.href=window.location.href for 'full' reload, i.e.:

<button onClick="window.location.href=window.location.href">Refresh Page</button>

MDN page on the <button> element.

In tandem with what Pedro Fontez said a few replies up, you seemed to never call the sys module initially, nor did you manage to stick the required () at the end of sys.exit:

so:

import sys

and when finished:

sys.exit()

The name of the hook script is not so scary if you manage decipher it: it's pre revision property change hook. In short, the purpose of pre-revprop-change hook script is to control changes of unversioned (revision) properties and to send notifications (e.g. to send an email when revision property is changed).

There are 2 types of properties in Subversion:

• versioned properties (e.g svn:needs-lock and svn:mime-type) that can be set on files and directories,
• unversioned (revision) properties (e.g. svn:log and svn:date) that are set on repository revisions.

Versioned properties have history and can be manipulated by ordinary users who have Read / Write access to a repository. On the other hand, unversioned properties do not have any history and serve mostly maintenance purpose. For example, if you commit a revision it immediately gets svn:date with UTC time of your commit, svn:author with your username and svn:log with your commit log message (if you specified any).

As I already specified, the purpose of pre-revprop-change hook script is to control changes of revision properties. You don't want everyone who has access to a repository to be able to modify all revision properties, so changing revision properties is forbidden by default. To allow users to change properties, you have to create pre-revprop-change hook.

The simplest hook can contain just one line: exit 0. It will allow any authenticated user to change any revision property and it should not be used in real environment. On Windows, you can use batch script or PowerShell-based script to implement some logic within pre-revprop-change hook.

This PowerShell script allows to change svn:log property only and denies empty log messages.

# Store hook arguments into variables with mnemonic names
$repos    = $args[0]
$rev      = $args[1]
$user     = $args[2]
$propname = $args[3]
$action   = $args[4]

# Only allow changes to svn:log. The author, date and other revision
# properties cannot be changed
if ($propname -ne "svn:log")
{
  [Console]::Error.WriteLine("Only changes to 'svn:log' revision properties are allowed.")
  exit 1
}

# Only allow modifications to svn:log (no addition/overwrite or deletion)
if ($action -ne "M")
{
  [Console]::Error.WriteLine("Only modifications to 'svn:log' revision properties are allowed.")
  exit 2
}

# Read from the standard input while the first non-white-space characters
$datalines = ($input | where {$_.trim() -ne ""})
if ($datalines.length -lt 25)
{
  # Log message is empty. Show the error.
  [Console]::Error.WriteLine("Empty 'svn:log' properties are not allowed.")
  exit 3
}

exit 0

This batch script allows only "svnmgr" user to change revision properties:

IF "%3" == "svnmgr" (goto :label1) else (echo "Only the svnmgr user may change revision properties" >&2 )

exit 1
goto :eof

:label1
exit 0

Instead of this:

cur.execute( "SELECT * FROM records WHERE email LIKE '%s'", search )

Try this:

cur.execute( "SELECT * FROM records WHERE email LIKE %s", [search] )

See the MySQLdb documentation. The reasoning is that execute's second parameter represents a list of the objects to be converted, because you could have an arbitrary number of objects in a parameterized query. In this case, you have only one, but it still needs to be an iterable (a tuple instead of a list would also be fine).

On older browsers, :hover only worked on <a> elements. So you'd have to do something like this to get it to work.

<style>
a#aks
{
    width:100px;
    height:100px;
    display:block;
}

a#aks:link
{
  background-image: url('http://dummyimage.com/100x100/000/fff');
}

a#aks:hover
{
  background-image: url('http://dummyimage.com/100x100/eb00eb/fff');
}
</style>

<a href="#" id="aks"></a>

I should point out that none of the answers provided so far give you the number of characters as you would expect, especially when you're dealing with emojis (but also some languages like Thai, Korean, or Arabic). VonC's suggestions will output the following:

fmt.Println(utf8.RuneCountInString("??")) // Outputs "6".
fmt.Println(len([]rune("??"))) // Outputs "6".

That's because these methods only count Unicode code points. There are many characters which can be composed of multiple code points.

Same for using the Normalization package:

var ia norm.Iter
ia.InitString(norm.NFKD, "??")
nc := 0
for !ia.Done() {
    nc = nc + 1
    ia.Next()
}
fmt.Println(nc) // Outputs "6".

Normalization is not really the same as counting characters and many characters cannot be normalized into a one-code-point equivalent.

masakielastic's answer comes close but only handles modifiers (the rainbow flag contains a modifier which is thus not counted as its own code point):

fmt.Println(GraphemeCountInString("??"))  // Outputs "5".
fmt.Println(GraphemeCountInString2("??")) // Outputs "5".

The correct way to split Unicode strings into (user-perceived) characters, i.e. grapheme clusters, is defined in the Unicode Standard Annex #29. The rules can be found in Section 3.1.1. The github.com/rivo/uniseg package implements these rules so you can determine the correct number of characters in a string:

fmt.Println(uniseg.GraphemeClusterCount("??")) // Outputs "2".

Use this line simply inside your head with

       window.location.reload(true);

It will load your current page or view.

Create dictionaries for both arrays using _.keyBy(), merge the dictionaries, and convert the result to an array with _.values(). In this way, the order of the arrays doesn't matter. In addition, it can also handle arrays of different length.

const ObjectId = (id) => id; // mock of ObjectId_x000D_
const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];_x000D_
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];_x000D_
_x000D_
const merged = _(arr1) // start sequence_x000D_
  .keyBy('member') // create a dictionary of the 1st array_x000D_
  .merge(_.keyBy(arr2, 'member')) // create a dictionary of the 2nd array, and merge it to the 1st_x000D_
  .values() // turn the combined dictionary to array_x000D_
  .value(); // get the value (array) out of the sequence_x000D_
_x000D_
console.log(merged);

Using ES6 Map

Concat the arrays, and reduce the combined array to a Map. Use Object#assign to combine objects with the same member to a new object, and store in map. Convert the map to an array with Map#values and spread:

const ObjectId = (id) => id; // mock of ObjectId_x000D_
const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];_x000D_
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];_x000D_
_x000D_
const merged = [...arr1.concat(arr2).reduce((m, o) => _x000D_
  m.set(o.member, Object.assign(m.get(o.member) || {}, o))_x000D_
, new Map()).values()];_x000D_
_x000D_
console.log(merged);

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

Try this:

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
     geom_bar(position = 'dodge', stat='identity') +
     geom_text(aes(label=Number), position=position_dodge(width=0.9), vjust=-0.25)

If you only want the position, vp.getCurrentItem() will give it to you, no need to apply the onPageChangeListener() for that purpose alone.

from two tables with foreign key you can try this Query:

DELETE T1, T2
FROM T1
INNER JOIN T2 ON T1.key = T2.key
WHERE condition

Something nobody has mentioned so far is to make handleRemove return a function.

You can do something like:

handleRemove = id => event => {
  // Do stuff with id and event
}

// render...
  return <button onClick={this.handleRemove(id)} />

However all of these solutions have the downside of creating a new function on each render. Better to create a new component for Button which gets passed the id and the handleRemove separately.

Bind the button, this is done with jQuery:

$("#my-table input[type='button']").click(function(){
    var parameter = $(this).val();
    window.location = "http://yoursite.com/page?variable=" + parameter;
});

this way worked better for me:

echo y | keytool -storepasswd -storepass 123456 -keystore /tmp/IT-Root-CA.keystore -import -alias IT-Root-CA -file /etc/pki/ca-trust/source/anchors/IT-Root-CA.crt

machine running:

[root@rhel80-68]# cat /etc/redhat-release 
Red Hat Enterprise Linux release 8.1 (Ootpa)

if you just want to temporarily disable the link but leave the href there to enable later (which is what I wanted to do) I found that all browsers use the first href. Hence I was able to do:

<a class="ea-link" href="javascript:void(0)" href="/export/">Export</a>

I prefer using .env file for different environment.

1. Use webpack.dev.config to copy env.dev to .env into root folder
2. Use webpack.prod.config to copy env.prod to .env

and in code

use

require('dotenv').config(); const API = process.env.API ## which will store the value from .env file

To add to Matt wilson's answer I had a bunch of code-first entity classes but no database as I hadn't taken a backup. So I did the following on my Entity Framework project:

Open Package Manager console in Visual Studio and type the following:

Enable-Migrations

Add-Migration

Give your migration a name such as 'Initial' and then create the migration. Finally type the following:

Update-Database

Update-Database -Script -SourceMigration:0

The final command will create your database tables from your entity classes (provided your entity classes are well formed).

In bootstrap you can use .text-centerto align center. also add .row and .col-md-* to your code.

align= is deprecated,

Added .col-xs-* for demo

UPDATE(OCT 2017)

For those who are reading this and want to use the new version of bootstrap (beta version), you can do the above in a simpler way, using Boostrap Flexbox utilities classes

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet" />
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container footer">
  <div class="d-flex justify-content-between">
    <div class="p-1">
      <p>Hello there</p>
    </div>
    <div class="p-1">
      <a href="#" class="btn btn-warning" onclick="changeLook()">Re</a>
      <a href="#" class="btn btn-warning" onclick="changeBack()">Rs</a>
    </div>
    <div class="p-1">
      <a href="#"><i class="fa fa-facebook-square fa-2x"></i></a>
      <a href="#"><i class="fa fa-twitter fa-2x"></i></a>
      <a href="#"><i class="fa fa-google-plus fa-2x"></i></a>
    </div>

You can use np.logaddexp (which implements the idea in @gg349's answer):

In [33]: d = np.array([[1089, 1093]])

In [34]: e = np.array([[1000, 4443]])

In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])

In [36]: log_res
Out[36]: -266.99999385580668

In [37]: res = exp(log_res)

In [38]: res
Out[38]: 1.1050349147204485e-116

Or you can use scipy.special.logsumexp:

In [52]: from scipy.special import logsumexp

In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))

In [54]: res
Out[54]: 1.1050349147204485e-116

With JQuery you can try this $(window).innerHeight() (Works for me on Chrome, FF and IE). With bootstrap modal I used something like the following;

$('#YourModal').on('show.bs.modal', function () {
    $('.modal-body').css('height', $(window).innerHeight() * 0.7);
});

Swift 5:

1- Create a String extension to get attributedText

extension String {

    var underLined: NSAttributedString {
        NSMutableAttributedString(string: self, attributes: [.underlineStyle: NSUnderlineStyle.single.rawValue])
    }

}

2- Use it

On buttons:

button.setAttributedTitle(yourButtonTitle.underLined, for: .normal)

On Labels:

label.attributedText = yourLabelTitle.underLined

Or Stoyboard version

Fun with function pointers (none of that new-fangled TMP needed):

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


#define MSB(typ) ((sizeof(typ) * CHAR_BIT) - 1)

void done(int x, int y);
void display(int x, int y);

void (*funcs[])(int,int)  = {
    done,
    display
};

void done(int x, int y)
{
    exit(0);
}

void display(int x, int limit)
{
    printf( "%d\n", x);
    funcs[(((unsigned int)(x-limit)) >> MSB(int)) & 1](x+1, limit);
}


int main()
{
    display(1, 1000);
    return 0;
}

As a side note: I took the prohibition against conditionals to extend to logical and relational operators as well. If you allow logical negation, the recursive call can be simplified to:

funcs[!!(limit-1)](x+1, limit-1);

I wrote about some of the limitations of correlated subqueries in Access/JET SQL a while back, and noted the syntax for joining multiple tables for SQL UPDATEs. Based on that info and some quick testing, I don't believe there's any way to do what you want with Access/JET in a single SQL UPDATE statement. If you could, the statement would read something like this:

UPDATE FUNCTIONS A
INNER JOIN (
  SELECT AA.Func_ID, Min(BB.Tax_Code) AS MinOfTax_Code
  FROM TAX BB, FUNCTIONS AA
  WHERE AA.Func_Pure<=BB.Tax_ToPrice AND AA.Func_Year= BB.Tax_Year
  GROUP BY AA.Func_ID
) B 
ON B.Func_ID = A.Func_ID
SET A.Func_TaxRef = B.MinOfTax_Code

Alternatively, Access/JET will sometimes let you get away with saving a subquery as a separate query and then joining it in the UPDATE statement in a more traditional way. So, for instance, if we saved the SELECT subquery above as a separate query named FUNCTIONS_TAX, then the UPDATE statement would be:

UPDATE FUNCTIONS
INNER JOIN FUNCTIONS_TAX
ON FUNCTIONS.Func_ID = FUNCTIONS_TAX.Func_ID
SET FUNCTIONS.Func_TaxRef = FUNCTIONS_TAX.MinOfTax_Code

However, this still doesn't work.

I believe the only way you will make this work is to move the selection and aggregation of the minimum Tax_Code value out-of-band. You could do this with a VBA function, or more easily using the Access DLookup function. Save the GROUP BY subquery above to a separate query named FUNCTIONS_TAX and rewrite the UPDATE statement as:

UPDATE FUNCTIONS
SET Func_TaxRef = DLookup(
  "MinOfTax_Code", 
  "FUNCTIONS_TAX", 
  "Func_ID = '" & Func_ID & "'"
)

Note that the DLookup function prevents this query from being used outside of Access, for instance via JET OLEDB. Also, the performance of this approach can be pretty terrible depending on how many rows you're targeting, as the subquery is being executed for each FUNCTIONS row (because, of course, it is no longer correlated, which is the whole point in order for it to work).

Good luck!

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

I guess you could open a popup window and call that a dialog box. I'm unsure of the details, but I'm pretty sure you can close a window programmatically that you opened from javascript. Would this suffice?

In Python 3, the reduce has been removed: Release notes. Nevertheless you can use the functools module

import operator, functools
def product(xs):
    return functools.reduce(operator.mul, xs, 1)

On the other hand, the documentation expresses preference towards for-loop instead of reduce, hence:

def product(xs):
    result = 1
    for i in xs:
        result *= i
    return result

• Variable Not Hoisting

  let will not hoist to the entire scope of the block they appear in. By contrast, var could hoist as below.

  {
     console.log(cc); // undefined. Caused by hoisting
     var cc = 23;
  }
  
  {
     console.log(bb); // ReferenceError: bb is not defined
     let bb = 23;
  }
  

  Actually, Per @Bergi, Both var and let are hoisted.

• Garbage Collection

  Block scope of let is useful relates to closures and garbage collection to reclaim memory. Consider,

  function process(data) {
      //...
  }
  
  var hugeData = { .. };
  
  process(hugeData);
  
  var btn = document.getElementById("mybutton");
  btn.addEventListener( "click", function click(evt){
      //....
  });
  

  The click handler callback does not need the hugeData variable at all. Theoretically, after process(..) runs, the huge data structure hugeData could be garbage collected. However, it's possible that some JS engine will still have to keep this huge structure, since the click function has a closure over the entire scope.

  However, the block scope can make this huge data structure to garbage collected.

  function process(data) {
      //...
  }
  
  { // anything declared inside this block can be garbage collected
      let hugeData = { .. };
      process(hugeData);
  }
  
  var btn = document.getElementById("mybutton");
  btn.addEventListener( "click", function click(evt){
      //....
  });
  

• let loops

  let in the loop can re-binds it to each iteration of the loop, making sure to re-assign it the value from the end of the previous loop iteration. Consider,

  // print '5' 5 times
  for (var i = 0; i < 5; ++i) {
      setTimeout(function () {
          console.log(i);
      }, 1000);  
  }
  

  However, replace var with let

  // print 1, 2, 3, 4, 5. now
  for (let i = 0; i < 5; ++i) {
      setTimeout(function () {
          console.log(i);
      }, 1000);  
  }
  

  Because let create a new lexical environment with those names for a) the initialiser expression b) each iteration (previosly to evaluating the increment expression), more details are here.

What if you had a <tbody> and a <tfoot>?

Such as:

<table>
    <tbody>
        <tr><td>Foo</td></tr>
    </tbody>
    <tfoot>
        <tr><td>footer information</td></tr>
    </tfoot>
</table>

Then it would insert your new row in the footer - not to the body.

Hence the best solution is to include a <tbody> tag and use .append, rather than .after.

$("#myTable > tbody").append("<tr><td>row content</td></tr>");

EDITED: This guy really brought it home and has a good little tutorial http://instantiatorgratification.blogspot.com/2013/05/google-play-services-with-android-studio.html

one side note: I had played around so much that I needed to do a gradlew clean to get it to run succesfully

If you have imported your project or are working from the Sample Maps application located in \extras\google\google_play_services\samples\maps check out this tutorial.

https://stackoverflow.com/a/16598478/2414698

If you are creating a new project from scratch then note Xav's comments on that same post. He describes that Android Studio uses a different compiler and that you have to modify the build.gradle file manually. I did this with success. I copied

• google-play-services.jar
• google-play-services.jar.properties

into my lib directory and added the following to my build.gradle file

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/google-play-services.jar')
}

Also, if this is a new project check out this post, too.

Tables are odd elements. Unlike divs they have special rules. Add cellspacing and cellpadding attributes, set to 0, and it should fix the problem.

<table id="page" width="100%" border="0" cellspacing="0" cellpadding="0">

First check - is the working directory the directory that the application is running in:

• Right-click on your project and select Properties.
• Click the Debug tab.
• Confirm that the Working directory is either empty or equal to the bin\debug directory.

If this isn't the problem, then ask if Autodesk.Navisworks.Timeliner.dll is requiring another DLL which is not there. If Timeliner.dll is not a .NET assembly, you can determine the required imports using the command utility DUMPBIN.

dumpbin /imports Autodesk.Navisworks.Timeliner.dll

If it is a .NET assembly, there are a number of tools that can check dependencies.

Reflector has already been mentioned, and I use JustDecompile from Telerik.

Open command prompt as admin and write :

bcdedit /set hypervisorlaunchtype off

This worked for me:

git remote set-url heroku <repo git>

This replacement old url heroku.

You can check with:

git remote -v

I've tried both design strategies - nested and non-nested endpoints. I've found that:

1. if the nested resource has a primary key and you don't have its parent primary key, the nested structure requires you to get it, even though the system doesn't actually require it.

2. nested endpoints typically require redundant endpoints. In other words, you will more often than not, need the additional /employees endpoint so you can get a list of employees across departments. If you have /employees, what exactly does /companies/departments/employees buy you?

3. nesting endpoints don't evolve as nicely. E.g. you might not need to search for employees now but you might later and if you have a nested structure, you have no choice but to add another endpoint. With a non-nested design, you just add more parameters, which is simpler.

4. sometimes a resource could have multiple types of parents. Resulting in multiple endpoints all returning the same resource.

5. redundant endpoints makes the docs harder to write and also makes the api harder to learn.

In short, the non-nested design seems to allow a more flexible and simpler endpoint schema.

As Andy said the document will be not valid, but nevertheless the script will still be interpreted. See the snippet from WebKit for example:

void HTMLParser::processCloseTag(Token* t)
{
    // Support for really broken html.
    // we never close the body tag, since some stupid web pages close it before 
    // the actual end of the doc.
    // let's rely on the end() call to close things.
    if (t->tagName == htmlTag || t->tagName == bodyTag 
                              || t->tagName == commentAtom)
        return;
    ...

A thing to look out for if you see this in React, is that the <form> still has to render in the DOM while it's submitting. i.e, this will fail

{ this.state.submitting ? 
     <div>Form is being submitted</div> :
     <form onSubmit={()=>this.setState({submitting: true}) ...>
         <button ...>
     </form>
}

So when the form is submitted, state.submitting gets set and the "submitting..." message renders instead of the form, then this error happens.

Moving the form tag outside the conditional ensured that it was always there when needed, i.e.

<form onSubmit={...} ...>
  { this.state.submitting ? 
     <div>Form is being submitted</div> :
     <button ...>
  }
</form>

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100, say, and your current client IDs are in Sheet1 in Column A.

What you would do is:

1. Select the whole data table you want conditionally formatted in Sheet1
2. Click Conditional Formatting > New Rule > Use a Formula to determine which cells to format
3. In the formula bar, type in =ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0)) and select how you want those rows formatted

And that should do the trick.

Simple one, just do like this..

ListViewItem lvi = new ListViewItem(pet.Name);
    lvi.SubItems.Add(pet.Type);
    lvi.SubItems.Add(pet.Age);
    listView.Items.Add(lvi);

Assuming that you want to get a value from the user input in html textbox whenever the user clicks 'Click' button, and then call a python function (mypythonfunction) that you wrote inside mypythoncode.py. Note that "btn" class is defined in a css file.

inside templateHTML.html:

<form action="#" method="get">
 <input type="text" value="8" name="mytextbox" size="1"/>
 <input type="submit" class="btn" value="Click" name="mybtn">
</form>

inside view.py:

import mypythoncode

def request_page(request):
  if(request.GET.get('mybtn')):
    mypythoncode.mypythonfunction( int(request.GET.get('mytextbox')) )
return render(request,'myApp/templateHTML.html')

You could use Twitter's snowflake.

In short, it generates a unique id based on time, server id and a sequence. It generates a 64-bit value so it is pretty small and it fits in an INT64. It also allows for sorting values correctly.

https://developer.twitter.com/en/docs/basics/twitter-ids

In sum, it allows multiple servers, highly concurrency, sorting value and all of them in 64 bits.

Here it is the implementation for MySQL

https://github.com/EFTEC/snowflake-mysql

It consists of a function and a table.

You need to start the Apache Tomcat services.

Win+R --> sevices.msc

Then, search for Apache Tomcat and right click on it and click on Start. This will start the service and then you'll be able to see Apache Tomcat homepage on the localhost .

If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible. In addition, your communication through higher-level APIs needs to be encrypted using TLS version 1.2 with forward secrecy. If you try to make a connection that doesn't follow this requirement, an error is thrown. If your app needs to make a request to an insecure domain, you have to specify this domain in your app's Info.plist file.

When use method delete in form then must have to set route delete

Route::delete("empresas/eliminar/{id}", "CompaniesController@delete");

I am not 100% sure what the conditions are for this, but for me the above didn't work directly, thought it got close. I think it was because I needed "id" for my view by in the model it was called "ObjectID".

I had a model with a variety of pieces of information. I just needed the id.

Before the above I created a new System.Web.Routing.RouteValueDictionary object and added the needed id.

(System.Web.Routing.)RouteValueDictionary RouteInfo = new RouteValueDictionary();
RouteInfo.Add("id", ObjectID);
return RedirectToAction("details", RouteInfo);

(Note: the MVC project in question I didn't create, so I don't know where all the right "fiddly" bits are.)

1. Close your solution in VS2012
2. Move your project to the new location
3. Open your solution
4. Select the project that failed to load
5. In the Properties tool window, there an editable “File path” entry that allows you to select the new project location
6. Set the new path
7. Right click on the project and click reload

You can use the values 'TRUE' and 'FALSE'. From https://docs.microsoft.com/en-us/sql/t-sql/data-types/bit-transact-sql:

The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.

For removing document, I prefer using Model.remove(conditions, [callback])

Please refer API documentation for remove :-

http://mongoosejs.com/docs/api.html#model_Model.remove

For this case, code will be:-

FBFriendModel.remove({ id : 333 }, function(err, callback){

If you want to remove documents without waiting for a response from MongoDB, do not pass a callback, then you need to call exec on the returned Query

var removeQuery = FBFriendModel.remove({id : 333 });
removeQuery.exec();

sys.dm_tran_locks contains the locking information of the sessions

If you want to know a specific table is locked or not, you can use the following query

SELECT 
 * 
from 
 sys.dm_tran_locks 
where 
  resource_associated_entity_id = object_id('schemaname.tablename')

if you are interested in finding both login name of the user and the query being run

SELECT
 DB_NAME(resource_database_id)
 , s.original_login_name
 , s.status
 , s.program_name
 , s.host_name
 , (select text from sys.dm_exec_sql_text(exrequests.sql_handle))
 ,*
from
  sys.dm_tran_locks dbl
     JOIN sys.dm_exec_sessions s ON dbl.request_session_id = s.session_id
  INNER JOIN  sys.dm_exec_requests exrequests on dbl.request_session_id = exrequests.session_id
where
 DB_NAME(dbl.resource_database_id) = 'dbname'

As noted in the accepted answer - you can use the special { props.children } property. However - you can just pass a component as a prop as the title requests. I think this is cleaner sometimes as you might want to pass several components and have them render in different places. Here's the react docs with an example of how to do it:

https://reactjs.org/docs/composition-vs-inheritance.html

Make sure you are actually passing a component and not an object (this tripped me up initially).

The code is simply this:

const Parent = () => { 
  return (
    <Child  componentToPassDown={<SomeComp />}  />
  )
}

const Child = ({ componentToPassDown }) => { 
  return (
    <>
     {componentToPassDown}  
    </>
  )
}

Bro, I had the same problem. Thing is I built a query builder, quite an complex one that build his predicates dynamically pending on what parameters had been set and cached the queries. Anyways, before I built my query builder, I had a non object oriented procedural code build the same thing (except of course he didn't cache queries and use parameters) that worked flawless. Now when my builder tried to do the very same thing, my PostgreSQL threw this fucked up error that you received too. I examined my generated SQL code and found no errors. Strange indeed.

My search soon proved that it was one particular predicate in the WHERE clause that caused this error. Yet this predicate was built by code that looked like, well almost, exactly as how the procedural code looked like before this exception started to appear out of nowhere.

But I saw one thing I had done differently in my builder as opposed to what the procedural code did previously. It was the order of the predicates he put in the WHERE clause! So I started to move this predicate around and soon discovered that indeed the order of predicates had much to say. If I had this predicate all alone, my query worked (but returned an erroneous result-match of course), if I put him with just one or the other predicate it worked sometimes, didn't work other times. Moreover, mimicking the previous order of the procedural code didn't work either. What finally worked was to put this demonic predicate at the start of my WHERE clause, as the first predicate added! So again if I haven't made myself clear, the order my predicates where added to the WHERE method/clause was creating this exception.

Note that from Netbeans 8 there is no Run panel in the project Properties.

To do what you want I simply add the following line (example setting the locale) in my project's properties file:

run.args.extra=--locale fr:FR

append( ) function and spread operator

Two slices can be concatenated using append method in the standard golang library. Which is similar to the variadic function operation. So we need to use ...

package main

import (
    "fmt"
)

func main() {
    x := []int{1, 2, 3}
    y := []int{4, 5, 6}
    z := append([]int{}, append(x, y...)...)
    fmt.Println(z)
}

output of the above code is: [1 2 3 4 5 6]

For Those who are facing difficulty just got to php admin and change collation to utf8_general_ci Select Table go to Operations>> table options>> collations should be there

you can use the sbstr() function

$amount = 1;   //where $amount the amount of string you want to delete starting  from index 0
$str = substr($str, $amount);

set -x is fine, but if you do something like:

set -x;
command;
set +x;

it would result in printing

+ command
+ set +x;

You can use a subshell to prevent that such as:

(set -x; command)

which would just print the command.

This command did it for me:

zip -r Target.zip Source -x "*.DS_Store"

Target.zip is the zip file to create. Source is the source file/folder to zip up. And the _x parameter specifies the file/folder to not include. If the above doesn't work for whatever reason, try this instead:

zip -r Target.zip Source -x "*.DS_Store" -x "__MACOSX"

Your question How can I just get the file-names (with paths)

Your syntax example find . -iname "*php" -exec grep -H myString {} \;

My Command suggestion

sudo find /home -name *.php

The output from this command on my Linux OS:

compose-sample-3/html/mail/contact_me.php

As you require the filename with path, enjoy!
