Programs & Examples On #Image upload

You need to use either PHP's ImageMagick or GD functions to work with images.

With GD, for example, it's as simple as...

function resize_image($file, $w, $h, $crop=FALSE) {
    list($width, $height) = getimagesize($file);
    $r = $width / $height;
    if ($crop) {
        if ($width > $height) {
            $width = ceil($width-($width*abs($r-$w/$h)));
        } else {
            $height = ceil($height-($height*abs($r-$w/$h)));
        }
        $newwidth = $w;
        $newheight = $h;
    } else {
        if ($w/$h > $r) {
            $newwidth = $h*$r;
            $newheight = $h;
        } else {
            $newheight = $w/$r;
            $newwidth = $w;
        }
    }
    $src = imagecreatefromjpeg($file);
    $dst = imagecreatetruecolor($newwidth, $newheight);
    imagecopyresampled($dst, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

    return $dst;
}

And you could call this function, like so...

$img = resize_image(‘/path/to/some/image.jpg’, 200, 200);

From personal experience, GD's image resampling does dramatically reduce file size too, especially when resampling raw digital camera images.

Sometimes the space after <?php visible if you are using the same editor, in my case I was using TextWrapper. Due to the file type configuration in the TextWrapper (in your case some other editor), you might not see the space. Use a different editor in your machine and you'll see it. Then remove them -- works perfectly afterward.

Just in case you were not able to accomplish the above code, here is a simple way of using it with jquery:

$.getJSON("http://www.geoplugin.net/json.gp?jsoncallback=?",
    function (data) {
        for (var i in data) {
            document.write('data["i"] = ' + i + '<br/>');
        }
    }
);

the following provides a solution such that to add a new enum requires only a one-line edit, similar work to adding a single line in an enum {} list.

//------------------------------------------------------------------------------
// enum to string example
#define FOR_EACH_GENDER(tbd) \
        tbd(GENDER_MALE) \
        tbd(GENDER_FEMALE) \
        tbd(GENDER_INTERSEX) \

#define ONE_GENDER_ENUM(name) name,
enum
{
    FOR_EACH_GENDER(ONE_GENDER_ENUM)
    MAX_GENDER
};

#define ONE_GENDER(name) #name,
static const char *enumGENDER_TO_STRING[] = 
{
    FOR_EACH_GENDER(ONE_GENDER)
};

// access string name with enumGENDER_TO_STRING[value]
// or, to be safe converting from a untrustworthy caller
static const char *enumGenderToString(unsigned int value)
{
    if (value < MAX_GENDER)
    {
        return enumGENDER_TO_STRING[value];
    }
    return NULL;
}

static void printAllGenders(void)
{
    for (int ii = 0;  ii < MAX_GENDER;  ii++)
    {
        printf("%d) gender %s\n", ii, enumGENDER_TO_STRING[ii]);
    }
}

//------------------------------------------------------------------------------
// you can assign an arbitrary value and/or information to each enum,
#define FOR_EACH_PERSON(tbd) \
        tbd(2, PERSON_FRED,     "Fred",     "Weasley", GENDER_MALE,   12) \
        tbd(4, PERSON_GEORGE,   "George",   "Weasley", GENDER_MALE,   12) \
        tbd(6, PERSON_HARRY,    "Harry",    "Potter",  GENDER_MALE,   10) \
        tbd(8, PERSON_HERMIONE, "Hermione", "Granger", GENDER_FEMALE, 10) \

#define ONE_PERSON_ENUM(value, ename, first, last, gender, age) ename = value,
enum
{
    FOR_EACH_PERSON(ONE_PERSON_ENUM)
};

typedef struct PersonInfoRec
{
    int value;
    const char *ename;
    const char *first;
    const char *last;
    int gender;
    int age;
} PersonInfo;

#define ONE_PERSON_INFO(value, ename, first, last, gender, age) \
                     { ename, #ename, first, last, gender, age },
static const PersonInfo personInfo[] = 
{
    FOR_EACH_PERSON(ONE_PERSON_INFO)
    { 0, NULL, NULL, NULL, 0, 0 }
};
// note: if the enum values are not sequential, you need another way to lookup
// the information besides personInfo[ENUM_NAME]

static void printAllPersons(void)
{
    for (int ii = 0;  ;  ii++)
    {
        const PersonInfo *pPI = &personInfo[ii];
        if (!pPI->ename)
        {
            break;
        }
        printf("%d) enum %-15s  %8s %-8s %13s %2d\n",
            pPI->value, pPI->ename, pPI->first, pPI->last,
            enumGenderToString(pPI->gender), pPI->age);
    }
}

Try:

AssetFileDescriptor afd = getAssets().openFd(fileName);
player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(), afd.getLength());

To exit hitting :q will let you quit.

If you want to quit without saving you can hit :q!

Whenever I need to do this I build a simple PL/SQL block with a local procedure like this:

declare
   procedure ins
   is

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

Elaborating on this answer and this answer.

Above answers point out the problem of many of the solutions here which don't iterate by code point value -- they would have trouble with any surrogate chars. The java docs also outline the issue here (see "Unicode Character Representations"). Anyhow, here's some code that uses some actual surrogate chars from the supplementary Unicode set, and converts them back to a String. Note that .toChars() returns an array of chars: if you're dealing with surrogates, you'll necessarily have two chars. This code should work for any Unicode character.

    String supplementary = "Some Supplementary: ";
    supplementary.codePoints().forEach(cp -> 
            System.out.print(new String(Character.toChars(cp))));

Make sure to select "All" to find the enable bitcode build settings:

Your code has two problems. One was identified and answered, but the other wasn't. The first was that your selector was missing the name of its parameter. However, even when you fix that, the line will still raise an exception, assuming your revised method signature still includes more than one argument. Let's say your revised method is declared as:

-(void)myTestWithString:(NSString *)sourceString comparedTo:(NSString *)testString ;

Creating selectors for methods that take multiple arguments is perfectly valid (e.g. @selector(myTestWithString:comparedTo:) ). However, the performSelector method only allows you to pass one value to myTest, which unfortunately has more than one parameter. It will error out and tell you that you didn't supply enough values.

You could always redefine your method to take a collection as it's only parameter:

-(void)myTestWithObjects:(NSDictionary *)testObjects ;

However, there is a more elegant solution (that doesn't require refactoring). The answer is to use NSInvocation, along with its setArgument:atIndex: and invoke methods.

I've written up an article, including a code example, if you want more details. The focus is on threading, but the basics still apply.

Good luck!

To answer the original question specifically (using IO.FileAttributes):

Get-ChildItem c:\mypath -Recurse | Where-Object {$_.Attributes -and [IO.FileAttributes]::Directory}

I do prefer Marek's solution though (Where-Object { $_ -is [System.IO.DirectoryInfo] }).

As per the documentation: This allows you to switch from the default ASCII to other encodings such as UTF-8, which the Python runtime will use whenever it has to decode a string buffer to unicode.

This function is only available at Python start-up time, when Python scans the environment. It has to be called in a system-wide module, sitecustomize.py, After this module has been evaluated, the setdefaultencoding() function is removed from the sys module.

The only way to actually use it is with a reload hack that brings the attribute back.

Also, the use of sys.setdefaultencoding() has always been discouraged, and it has become a no-op in py3k. The encoding of py3k is hard-wired to "utf-8" and changing it raises an error.

I suggest some pointers for reading:

The ALT attribute is for the visually impaired user that would use a screen reader. If the ALT is missing from ANY image tag, the entire url for the image will be read. If the images are for part of the design of the site, they should still have the ALT but they can be left empty so the url doesn't have to be read for every part of the site.

The problem is that flex: 1 sets flex-basis: 0. Instead, you need

.container .box {
  min-width: 200px;
  max-width: 400px;
  flex-basis: auto; /* default value */
  flex-grow: 1;
}

.container {_x000D_
  display: -webkit-flex;_x000D_
  display: flex;_x000D_
  -webkit-flex-wrap: wrap;_x000D_
  flex-wrap: wrap;_x000D_

If you want to modify only the first commit, you may try git rebase and amend the commit, which is similar to this post: How to modify a specified commit in git?

And if you want to modify all the commits which contain the raw email, filter-branch is the best choice. There is an example of how to change email address globally on the book Pro Git, and you may find this link useful http://git-scm.com/book/en/Git-Tools-Rewriting-History

I had problems aligning the label to the input(s) elements so I transferred the label element inside the form-inline and form-group too...and it works..

<div class="form-group">
    <div class="col-xs-10">
        <div class="form-inline">
            <div class="form-group">
                <label for="birthday" class="col-xs-2 control-label">Birthday:</label>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="year"/>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="month"/>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="day"/>
            </div>
        </div>
    </div>
</div>

NullPointerException in some cases! Without criteria.setProjection(Projections.distinct(Projections.property("id"))) all query goes well! This solution is bad!

Another way is use SQLQuery. In my case following code works fine:

List result = getSession().createSQLQuery(
"SELECT distinct u.id as usrId, b.currentBillingAccountType as oldUser_type,"
+ " r.accountTypeWhenRegister as newUser_type, count(r.accountTypeWhenRegister) as numOfRegUsers"
+ " FROM recommendations r, users u, billing_accounts b WHERE "
+ " r.user_fk = u.id and"
+ " b.user_fk = u.id and"
+ " r.activated = true and"
+ " r.audit_CD > :monthAgo and"
+ " r.bonusExceeded is null and"
+ " group by u.id, r.accountTypeWhenRegister")
.addScalar("usrId", Hibernate.LONG)
.addScalar("oldUser_type", Hibernate.INTEGER)
.addScalar("newUser_type", Hibernate.INTEGER)
.addScalar("numOfRegUsers", Hibernate.BIG_INTEGER)
.setParameter("monthAgo", monthAgo)
.setMaxResults(20)
.list();

Distinction is done in data base! In opposite to:

criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

where distinction is done in memory, after load entities!

for Material design, I just changed the floating action button color like this, Add the below two lines in your Floating action button xml. And done,

 android:backgroundTint="@color/colorPrimaryDark"
 app:borderWidth="0dp"

It is because you use a relative path.

The easy way to fix this is by using the __DIR__ magic constant, like:

require_once(__DIR__."/initcontrols/config.php");

From the PHP doc:

The directory of the file. If used inside an include, the directory of the included file is returned

According to my Scenario, I did "use CASE statement in WHERE IN clause" like following

@AdjType varchar(20) = 'Value', 
@Base varchar(20) = 'Common'
where 
(select CASE WHEN SA.IsPersentage = 0 THEN 'Value' 
       WHEN SA.IsPersentage = 1 THEN 'Presentage' END) Like @AdjType
and (Select CASE WHEN SA.IsDependOnBasicSalary = 0 THEN 'Common' 
        WHEN SA.IsDependOnBasicSalary = 1 THEN 'Basic Salary' END) like @Base

You can use the dataSourceClassName approach, here is an example with MySQL. (Tested with spring boot 1.3 and 1.4)

First you need to exclude tomcat-jdbc from the classpath as it will be picked in favor of hikaricp.

pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.apache.tomcat</groupId>
                <artifactId>tomcat-jdbc</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

application.properties

spring.datasource.dataSourceClassName=com.mysql.jdbc.jdbc2.optional.MysqlDataSource
spring.datasource.dataSourceProperties.serverName=localhost
spring.datasource.dataSourceProperties.portNumber=3311
spring.datasource.dataSourceProperties.databaseName=mydb
spring.datasource.username=root
spring.datasource.password=root

Then just add

@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

I created a test project here: https://github.com/ydemartino/spring-boot-hikaricp

This will work fast:

Case 1 - File2 = File1 + extra text appended.

grep -Fxvf File2.txt File1.txt >> File3.txt

File 1: 80 Lines File 2: 100 Lines File 3: 20 Lines

I've written shyaml in python for YAML query needs from the shell command line.

Overview:

$ pip install shyaml      ## installation

Example's YAML file (with complex features):

$ cat <<EOF > test.yaml
name: "MyName !!"
subvalue:
    how-much: 1.1
    things:
        - first
        - second
        - third
    other-things: [a, b, c]
    maintainer: "Valentin Lab"
    description: |
        Multiline description:
        Line 1
        Line 2
EOF

Basic query:

$ cat test.yaml | shyaml get-value subvalue.maintainer
Valentin Lab

More complex looping query on complex values:

$ cat test.yaml | shyaml values-0 | \
  while read -r -d $'\0' value; do
      echo "RECEIVED: '$value'"
  done
RECEIVED: '1.1'
RECEIVED: '- first
- second
- third'
RECEIVED: '2'
RECEIVED: 'Valentin Lab'
RECEIVED: 'Multiline description:
Line 1
Line 2'

A few key points:

• all YAML types and syntax oddities are correctly handled, as multiline, quoted strings, inline sequences...
• \0 padded output is available for solid multiline entry manipulation.
• simple dotted notation to select sub-values (ie: subvalue.maintainer is a valid key).
• access by index is provided to sequences (ie: subvalue.things.-1 is the last element of the subvalue.things sequence.)
• access to all sequence/structs elements in one go for use in bash loops.
• you can output whole subpart of a YAML file as ... YAML, which blend well for further manipulations with shyaml.

More sample and documentation are available on the shyaml github page or the shyaml PyPI page.

Mongodb user management:

Here's another difference. I will... buy you a beer if you can explain the reasoning or reason as to this state of affairs:

enum Foo { a = 'a', b = 'b' }

type TFoo = {
  [k in Foo]: boolean;
}

const foo1: TFoo = { a: true, b: false} // good
// const foo2: TFoo = { a: true }       // bad: missing b
// const foo3: TFoo = { a: true, b: 0}  // bad: b is not a boolean

// So type does roughly what I'd expect and want

interface IFoo {
//  [k in Foo]: boolean;
/*
  Uncommenting the above line gives the following errors:
  A computed property name in an interface must refer to an expression whose type is a      
    literal type or a 'unique symbol' type.
  A computed property name must be of type 'string', 'number', 'symbol', or 'any'.
  Cannot find name 'k'.
*/
}

// ???

This sort of makes me want to say the hell with interfaces unless I'm intentionally implementing some OOP design pattern, or require merging as described above (which I'd never do unless I had a very good reason for it).

If I understand correctly, you assumed that -v is the "print version" command. Check the documentation, that is not the case -- instead ant -v is running ant build in verbose mode. So ant is trying to perform your build, based on the build.xml file, which is obviously not there.

To answer your question explicitly: there is probably nothing wrong with both the system nor ant installation.

Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String s = formatter.format(date);

This is a bit of a complicated question, but it seems like the most direct route would be to load the XML document or XML string via MSXML2.DOMDocument which will then allow you to access the XML nodes.

You can find more on MSXML2.DOMDocument at the following sites:

• Manipulating XML files with Excel VBA & Xpath
• MSXML - http://msdn.microsoft.com/en-us/library/ms763742(VS.85).aspx
• An Overview of MSXML 4.0

Use the following in the function you will call and it will work just fine.

     [a b c] = yourfunction(optional)
     %your code
     a = 5;
     b = 7;
     c = 10;
     return
     end

This is a way to call the function both from another function and from the command terminal

     [aa bb cc] = yourfunction(optional);

The variables aa, bb and cc now hold the return variables.

The Bundler docs address this question as well:

ORIGINAL: http://gembundler.com/v1.3/rationale.html

EDIT: http://web.archive.org/web/20160309170442/http://bundler.io/v1.3/rationale.html

See the section called "Checking Your Code into Version Control":

After developing your application for a while, check in the application together with the Gemfile and Gemfile.lock snapshot. Now, your repository has a record of the exact versions of all of the gems that you used the last time you know for sure that the application worked. Keep in mind that while your Gemfile lists only three gems (with varying degrees of version strictness), your application depends on dozens of gems, once you take into consideration all of the implicit requirements of the gems you depend on.

This is important: the Gemfile.lock makes your application a single package of both your own code and the third-party code it ran the last time you know for sure that everything worked. Specifying exact versions of the third-party code you depend on in your Gemfile would not provide the same guarantee, because gems usually declare a range of versions for their dependencies.

The next time you run bundle install on the same machine, bundler will see that it already has all of the dependencies you need, and skip the installation process.

Do not check in the .bundle directory, or any of the files inside it. Those files are specific to each particular machine, and are used to persist installation options between runs of the bundle install command.

If you have run bundle pack, the gems (although not the git gems) required by your bundle will be downloaded into vendor/cache. Bundler can run without connecting to the internet (or the RubyGems server) if all the gems you need are present in that folder and checked in to your source control. This is an optional step, and not recommended, due to the increase in size of your source control repository.

It's better to avoid using unnecessary javascript. You can take advantage of the label tag to expand the click target of the input like so:

<label>
  <input type="file" style="display: none;">
  <a>Open</a>
</label>

Even though input is hidden, the link still works as a click target for it, and you can style it however you want.

To add color to an input, Use the following css code:

input{
     color: black;
}

I stumbled upon an interesting reason for a gigantic .xlsx file. Original workbook had 20 sheets or so, was 20 MB I made a new workbook with 1 of the sheets, so it would be more manageable: still 11.5 MB Imagine my surprise to find that the single sheet in the new workbook had 1,041,776 (count 'em!) blank rows. Now it's 13.5 KB

It turns out that because of a peculiar mixture of javascript frameworks that I needed to initiate the script using an event listener provide by one of the other frameworks.

you have to call it like this

SELECT dbo.CheckIfSFExists(23, default)

From Technet:

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called in order to retrieve the default value. This behaviour is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value. An exception to this behaviour is when invoking a scalar function by using the EXECUTE statement. When using EXECUTE, the DEFAULT keyword is not required.

import UIKit

let characters = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]

var a: String = characters.randomElement()!
var b: String = characters.randomElement()!
var c: String = characters.randomElement()!
var d: String = characters.randomElement()!
var e: String = characters.randomElement()!
var f: String = characters.randomElement()!
var password = ("\(a)" + "\(b)" + "\(c)" + "\(d)" + "\(e)" + "\(f)")

    print ( password)

You can do it easy....

1) create a boolean variable ...

private boolean bolBroacastRegistred;

2) When you register your Broadcast Receiver, set it to TRUE

...
bolBroacastRegistred = true;
this.registerReceiver(mReceiver, new IntentFilter(BluetoothDevice.ACTION_FOUND));
....

3) In the onPause() do it...

if (bolBroacastRegistred) {
    this.unregisterReceiver(mReceiver);
    bolBroacastRegistred = false
}

Just it, and now, you will not receive more exception error message on onPause().

Tip1: Always use the unregisterReceiver() in onPause() not in onDestroy() Tip2: Dont forget to set the bolBroadcastRegistred variable to FALSE when run the unregisterReceive()

Success!

The JSON format:

[{
    "org_name": "Asset Management"
}, {
    "org_name": "Debt Equity Foreign services"
}, {
    "org_name": "Credit Services"
}]

And the jQuery code to populate the values to the Dropdown on Ajax success:

success: function(json) {
    var options = [];
    $('#org_category').html('');  // Set the Dropdown as Blank before new Data
    options.push('<option>-- Select Category --</option>');
    $.each(JSON.parse(json), function(i, item) {
        options.push($('<option/>',
        {
           value: item.org_name, text: item.org_name
        }));
    });
    $('#org_category').append(options);  // Set the Values to Dropdown
}

More generally, I think you might want to get "top" of the rows that are sorted within a given group.

For the case of where a single value is max'd out, you have essentially sorted by only one column. However, it's often useful to hierarchically sort by multiple columns (for example: a date column and a time-of-day column).

# Answering the question of getting row with max "value".
df %>% 
  # Within each grouping of A and B values.
  group_by( A, B) %>% 
  # Sort rows in descending order by "value" column.
  arrange( desc(value) ) %>% 
  # Pick the top 1 value
  slice(1) %>% 
  # Remember to ungroup in case you want to do further work without grouping.
  ungroup()

# Answering an extension of the question of 
# getting row with the max value of the lowest "C".
df %>% 
  # Within each grouping of A and B values.
  group_by( A, B) %>% 
  # Sort rows in ascending order by C, and then within that by 
  # descending order by "value" column.
  arrange( C, desc(value) ) %>% 
  # Pick the one top row based on the sort
  slice(1) %>% 
  # Remember to ungroup in case you want to do further work without grouping.
  ungroup()

If you need minimal value for particular column

min(data[,2])

Note: R considers NA both the minimum and maximum value so if you have NA's in your column, they return: NA. To remedy, use:

min(data[,2], na.rm=T)

You can use Random.nextInt(n). This returns a random int in [0,n). Just using max-min+1 in place of n and adding min to the answer will give a value in the desired range.

To expand on Ryan's answer:

Whenever setStateValues is called, React re-renders your component, which means that the function body of the StateSelector component function gets re-executed.

React docs:

setState() will always lead to a re-render unless shouldComponentUpdate() returns false.

Essentially, you're setting state with:

setStateValues(allowedState);

causing a re-render, which then causes the function to execute, and so on. Hence, the loop issue.

To illustrate the point, if you set a timeout as like:

  setTimeout(
    () => setStateValues(allowedState),
    1000
  )

Which ends the 'too many re-renders' issue.

In your case, you're dealing with a side-effect, which is handled with UseEffectin your component functions. You can read more about it here.

Seems like Middleware is the way to go.
Refer the official documentation and this issue on their repo

printf

1. printf is used to perform output on the screen.
2. syntax = printf("control string ", argument );
3. It is not associated with File input/output

fprintf

1. The fprintf it used to perform write operation in the file pointed to by FILE handle.
2. The syntax is fprintf (filename, "control string ", argument );
3. It is associated with file input/output

ls spends more time sorting the files names. Use -f to disable the sorting, which will save some time:

ls -f | wc -l

Or you can use find:

find . -type f | wc -l

The closest you can do (except for your base-interface approach) is "where T : class", meaning reference-type. There is no syntax to mean "any interface".

This ("where T : class") is used, for example, in WCF to limit clients to service contracts (interfaces).

As someone who has worked with ASP.NET API for about 3 years, I'd recommend returning an HttpResponseMessage instead. Don't use the ActionResult or IEnumerable!

ActionResult is bad because as you've discovered.

Return IEnumerable<> is bad because you may want to extend it later and add some headers, etc.

Using JsonResult is bad because you should allow your service to be extendable and support other response formats as well just in case in the future; if you seriously want to limit it you can do so using Action Attributes, not in the action body.

public HttpResponseMessage GetAllNotificationSettings()
{
    var result = new List<ListItems>();
    // Filling the list with data here...

    // Then I return the list
    return Request.CreateResponse(HttpStatusCode.OK, result);
}

In my tests, I usually use the below helper method to extract my objects from the HttpResponseMessage:

 public class ResponseResultExtractor
    {
        public T Extract<T>(HttpResponseMessage response)
        {
            return response.Content.ReadAsAsync<T>().Result;
        }
    }

var actual = ResponseResultExtractor.Extract<List<ListItems>>(response);

In this way, you've achieved the below:

• Your Action can also return Error Messages and status codes like 404 not found so in the above way you can easily handle it.
• Your Action isn't limited to JSON only but supports JSON depending on the client's request preference and the settings in the Formatter.

Look at this: http://www.asp.net/web-api/overview/formats-and-model-binding/content-negotiation

As indicated here https://stackoverflow.com/a/1632004/330867, you can implement it by "filtering" what is originating the exit of this page.

As mentionned in the comments, here's a new version of the code in the other question, which also include the ajax request you make in your question :

var canExit = true;

// For every function that will call an ajax query, you need to set the var "canExit" to false, then set it to false once the ajax is finished.

function checkCart() {
  canExit = false;
  $.ajax({
    url : 'index.php?route=module/cart/check',
    type : 'POST',
    dataType : 'json',
    success : function (result) {
       if (result) {
        canExit = true;
       }
    }
  })
}

$(document).on('click', 'a', function() {canExit = true;}); // can exit if it's a link
$(window).on('beforeunload', function() {
    if (canExit) return null; // null will allow exit without a question
    // Else, just return the message you want to display
    return "Do you really want to close?";
});

Important: You shouldn't have a global variable defined (here canExit), this is here for simpler version.

Note that you can't override completely the confirm message (at least in chrome). The message you return will only be prepended to the one given by Chrome. Here's the reason : How can I override the OnBeforeUnload dialog and replace it with my own?

Why you don't use a DELETE CASCADE FK ?

Since eval() is evil, and new Function() is not the most efficient way to achieve this, here is a quick JS function that returns the function from its name in string.

• Works for namespace'd functions
• Fallbacks to null-function in case of null/undefined string
• Fallbacks to null-function if function not found

    function convertStringtoFunction(functionName){

        var nullFunc = function(){}; // Fallback Null-Function
        var ret = window; // Top level namespace

        // If null/undefined string, then return a Null-Function
        if(functionName==null) return nullFunc;

        // Convert string to function name
        functionName.split('.').forEach(function(key){ ret = ret[key]; });

        // If function name is not available, then return a Null-Function else the actual function
        return (ret==null ? nullFunc : ret);

    }

Usage:

    convertStringtoFunction("level1.midLevel.myFunction")(arg1, arg2, ...);

Here is solution for Hibernate 4.3.7.Final.

        )
    })

    }

    @Override
    public Date fromStringValue(String xml) throws HibernateException {
        return fromString(xml);
    }
}

This solution mostly relies on TimestampType implementation with adding additional behaviour through anonymous class of type JdbcTimestampTypeDescriptor.

This is my generic solution

public static IEnumerable<T> Remove<T>(this IEnumerable<T> items, Func<T, bool> match)
    {
        var list = items.ToList();
        for (int idx = 0; idx < list.Count(); idx++)
        {
            if (match(list[idx]))
            {
                list.RemoveAt(idx);
                idx--; // the list is 1 item shorter
            }
        }
        return list.AsEnumerable();
    }

It would look much simpler if extension methods support passing by reference ! usage:

var result = string[]{"mike", "john", "ali"}
result = result.Remove(x => x.Username == "mike").ToArray();
Assert.IsTrue(result.Length == 2);

EDIT: ensured that the list looping remains valid even when deleting items by decrementing the index (idx).

For me, it was a problem with my credentials

After trying some of the answer, one of them helped me to solve the problem:

Running git fetch threw the following error:

Could not resolve host: bitbucket.org

All I had to do was force my IDE (VS Code in my case) to remember my credentials:

git config --global credential.helper wincred

Git immediately synched all the changes, and git checkout <branche> works fine now!

Best solution

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

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

If you store your image in folder public, try this steps:

For example your image is sample.jpg and your path is public/img/sample.jpg so this codes will delete your image

use Illuminate\Support\Facades\File;
.
.
.


public function deleteImage(){

   $imgWillDelete = public_path() . '/img/sample.jpg';
   File::delete($imgWillDelete);
}

Just remove the obsolete gems from your Gemfile. If you're talking about Heroku (you didn't mention that) then the slug is compiled each new release, just using the current contents of that file.

Many of them has a given a different working answers, and i too got the same lint errors i make it ignore by doing the following with eclipse.

1. click on Windows
2. click on preferences
3. select android > Lint Error Checking.
4. click on ignore All > Apply > Ok.

Thats it.

I think it's important to add a thing, if you use the layout inflation that constructor in the drawview is not correct, add these constructors in the class:

public DrawingView(Context c, AttributeSet attrs) {
    super(c, attrs);
    ...
}

public DrawingView(Context c, AttributeSet attrs, int defStyle) {
    super(c, attrs, defStyle);
    ...
}

or the android system fails to inflate the layout file. I hope this could to help.

I had the same problem what i found was that the certificate .crt file i provided missing an intermediate certificate. So I asked all .crt files from my server admin, then concatinated them in reverse order.

Ex. 1. Root.crt 2. Inter.crt 3. myCrt.crt

in windows i executed copy Inter.crt + Root.crt newCertificate.crt

(Here i ignored myCrt.crt)

Then i provided newCertificate.crt file into code via inputstream. Work done.

I just had this problem setting up my new laptop. The issue for me was that my toolchain (CodeSourcery) is 32bit and I had not installed the 32bit libs.

sudo apt-get install ia32-libs

I organize packages by feature, not by patterns or implementation roles. I think packages like:

• beans
• factories
• collections

are wrong.

I prefer, for example:

• orders
• store
• reports

so I can hide implementation details through package visibility. Factory of orders should be in the orders package so details about how to create an order are hidden.

Check out the Maven Properties Guide...

As Seshagiri pointed out in the comments, ${env.VARIABLE_NAME} will do what you want.

I will add a word of warning and say that a pom.xml should completely describe your project so please use environment variables judiciously. If you make your builds dependent on your environment, they are harder to reproduce

I had this problem and I didn't have my url ready untill the callback would return some data. The solution was to open blank window before starting the callback and then just set the location when the callback returns.

$scope.testCode = function () {
    var newWin = $window.open('', '_blank');
    service.testCode().then(function (data) {
        $scope.testing = true;
        newWin.location = '/Tests/' + data.url.replace(/["]/g, "");
    });
};

While you can use a virtualenv, you don't need to. The trick is passing the PEP370 --user argument to the setup.py script. With the latest version of pip, one way to do it is:

pip install --user mercurial

This should result in the hg script being installed in $HOME/.local/bin/hg and the rest of the hg package in $HOME/.local/lib/pythonx.y/site-packages/.

Note, that the above is true for Python 2.6. There has been a bit of controversy among the Python core developers about what is the appropriate directory location on Mac OS X for PEP370-style user installations. In Python 2.7 and 3.2, the location on Mac OS X was changed from $HOME/.local to $HOME/Library/Python. This might change in a future release. But, for now, on 2.7 (and 3.2, if hg were supported on Python 3), the above locations will be $HOME/Library/Python/x.y/bin/hg and $HOME/Library/Python/x.y/lib/python/site-packages.

If you're not completely attached to using "from" and "to" as your option names, it's fairly easy to implement this using getopts:

while getopts f:t: opts; do
   case ${opts} in
      f) FROM_VAL=${OPTARG} ;;
      t) TO_VAL=${OPTARG} ;;
   esac
done

getopts is a program that processes command line arguments and conveniently parses them for you.

f:t: specifies that you're expecting 2 parameters that contain values (indicated by the colon). Something like f:t:v says that -v will only be interpreted as a flag.

opts is where the current parameter is stored. The case statement is where you will process this.

${OPTARG} contains the value following the parameter. ${FROM_VAL} for example will get the value /home/kristoffer/test.png if you ran your script like:

ocrscript.sh -f /home/kristoffer/test.png -t /home/kristoffer/test.txt

As the others are suggesting, if this is your first time writing bash scripts you should really read up on some basics. This was just a quick tutorial on how getopts works.

As the error code says, "no alternative certificate subject name matches target host name" - so there is an issue with the SSL certificate.

The certificate should include SAN, and only SAN will be used. Some browsers ignore the deprecated Common Name.

RFC 2818 clearly states "If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead."

If it's fragment,

Toast.makeText(getActivity(), "this is my Toast message!!! =)",
                   Toast.LENGTH_LONG).show();

You are accessing an object that is not defined.

The solution is check for null or undefined (to see whether the object exists) and only then iterate.

I had the same issue... Installing the EF from Package Manager Console worked for me

the command was: Install-Package EntityFramework

When I was trying to accomplish something very similar, I ended up doing something along these lines:

wp-content/themes/resources/functions.php

add_action('init', 'my_php_function');
function my_php_function() {
    if (stripos($_SERVER['REQUEST_URI'], 'page-with-custom-php') !== false) {
        // add desired php code here
    }
}

I started off by using IDEs, Microsoft or not. Then, while working on QNX some long time ago, I was forced to do with a text editor + compiler/linker. Now I prefer this simple combination––a syntax highlighting editor + C compiler and linker cli + make––to any IDEs, even if environment allows for them.

The reasons are, for me:

1. it's everywhere. If you program in C, you do have the compiler, and usually you can get yourself an editor. The first thing I do––I get myself nedit on Linux or Notepad++ on Windows. I would go with vi, but GUI editors provide for a better fonts, and that is important when you look at code all day

2. you can program remotely, via ssh, when you need to. And it does help a lot sometimes to be able to ssh into the target and do some quick things there

3. it keeps me close to CLI, preferably UNIX/Linux CLI. So all the commands are on my fingertips, and when I need them I don't have to go read a reference book. And UNIX CLI can do things IDEs often can't––because their developers didn't think you'd need them

4. most importantly, it is very much like seeing the Matrix in raw code. I operate files, so I'm forced to keep them manageable. I'm finding things in my code manually, which makes me keep it simple and organized. I do Config Management explicitly, so I know when I'm synced and how. I know my Makefiles because I write them, and they only do what I tell them to

   (if you wonder if that works in "really big projects"––it does work, and the bigger the project the more performance it gains me)

5. when people ask me to look at their code, I don't have to learn the IDE they use

I forgot to comment out a line with a MsgBox before executing my macro. Meaning I'd have to click OK over a hundred thousand times. The ESC key was just escaping the message box but not stopping the execution of the macro. Holding the ESC key continuously for a few seconds helped me stop the execution of the code.

Both std::string and std::vector<T> have constructors initializing the object to be empty. You could use std::vector<unsigned char>() but I'd remove the initializer.

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
    FROM DBA_SEGMENTS DS
    WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES) AND SEGMENT_NAME='YOUR_TABLE_NAME'
    GROUP BY DS.TABLESPACE_NAME, SEGMENT_NAME;

  visibility: visible;
  opacity: 1;
}

Here is the source of the example from w3schools

Write below code in your MainActivity.java file instead of your code.

public class MainActivity extends Activity implements OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button mBtn1 = (Button) findViewById(R.id.mBtn1);
        mBtn1.setOnClickListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    @Override
    public void onClick(View v) {
        Log.i("clicks","You Clicked B1");
        Intent i=new Intent(MainActivity.this, MainActivity2.class);
        startActivity(i);
    }
}

And Declare MainActivity2 into your Androidmanifest.xml file using below code.

<activity
    android:name=".MainActivity2"
    android:label="@string/title_activity_main">
</activity>

Another way this can occur is if you start a new project from one of the samples. When you later decide to change the package name from com.example.android.foo to your own domain, you will need to modify several values in the manifest and in individual .java files.

If you're in Eclipse, find the package statement for the .java file and choose QuickFix. There may be several choices there, but the one you want is the one that indicates to "Move 'foo.java' to package 'com.youdomain.android.yourapp'. Save the file and it may autobuild or do as others have suggested and try "Project->Clean".

The volatile keyword is used:

• to make non atomic 64-bit operations atomic: long and double. (all other, primitive accesses are already guaranteed to be atomic!)
• to make variable updates guaranteed to be seen by other threads + visibility effects: after writing to a volatile variable, all the variables that where visible before writing that variable become visible to another thread after reading the same volatile variable (happen-before ordering).

The java.util.concurrent.atomic.* classes are, according to the java docs:

A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form:

boolean compareAndSet(expectedValue, updateValue);

The atomic classes are built around the atomic compareAndSet(...) function that maps to an atomic CPU instruction. The atomic classes introduce the happen-before ordering as the volatile variables do. (with one exception: weakCompareAndSet(...)).

From the java docs:

When a thread sees an update to an atomic variable caused by a weakCompareAndSet, it does not necessarily see updates to any other variables that occurred before the weakCompareAndSet.

To your question:

Does this mean that whosoever takes lock on it, that will be setting its value first. And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

You don't lock anything, what you are describing is a typical race condition that will happen eventually if threads access shared data without proper synchronization. As already mentioned declaring a variable volatile in this case will only ensure that other threads will see the change of the variable (the value will not be cached in a register of some cache that is only seen by one thread).

What is the difference between AtomicInteger and volatile int?

AtomicInteger provides atomic operations on an int with proper synchronization (eg. incrementAndGet(), getAndAdd(...), ...), volatile int will just ensure the visibility of the int to other threads.

Add this to an htaccess file (and see edit notes added below):

<IfModule mod_php5.c>
   php_value post_max_size 200M
   php_value upload_max_filesize 200M
   php_value memory_limit 300M
   php_value max_execution_time 259200
   php_value max_input_time 259200
   php_value session.gc_maxlifetime 1200
</IfModule>

2021 EDIT:

As PHP and Apache evolve and grow, I think it is important for me to take a moment to mention a few things to consider and possible "gotchas" to consider:

• PHP can be run as a module or as CGI. It is not recommended to run as CGI as it creates a lot of opportunities for attack vectors [Read More]. Running as a module (the safer option) will trigger the settings to be used if the specific module from <IfModule is loaded.
• The answer indicates to write mod_php5.c in the first line. If you are using PHP 7, you would replace that with mod_php7.c.
• Sometimes after you make changes to your .htaccess file, restarting Apache or NGINX will not work. The most common reason for this is you are running PHP-FPM, which runs as a separate process. You need to restart that as well.
• Remember these are settings that are normally defined in your php.ini config file(s). This method is usually only useful in the event your hosting provider does not give you access to change those files. In circumstances where you can edit the PHP configuration, it is recommended that you apply these settings there.
• Finally, it's important to note that not all php.ini settings can be configured via an .htaccess file. A file list of php.ini directives can be found here, and the only ones you can change are the ones in the changeable column with the modes PHP_INI_ALL or PHP_INI_PERDIR.

Nobody did point the subtle difference in the semantics of the functions name() and local-name().

• name(someNode) returns the full name of the node, and that includes the prefix and colon in case the node is an element or an attribute.
• local-name(someNode) returns only the local name of the node, and that doesn't include the prefix and colon in case the node is an element or an attribute.

Therefore, in situations where a name may belong to two different namespaces, one must use the name() function in order for these names to be still distinguished.

And, BTW, it is possible to specify both functions without any argument:

name() is an abbreviation for name(.)

local-name() is an abbreviation for local-name(.)

Finally, do remember that not only elements and attributes have names, these two functions can also be used on PIs and on these they are identical).

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

Try to add the path to tnsnames.ora to the config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <oracle.manageddataaccess.client>
    <version number="4.112.3.60">
      <settings>
        <setting name="TNS_ADMIN" value="C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\" />
      </settings>
    </version>
  </oracle.manageddataaccess.client>
</configuration>

Lets say your HTML looks something like this:

<div class="box">
    <!-- stuff -->
    <p class="bet_time">Bet 5 days ago</p>
</div>

Then, with CSS, you can make that text appear in the bottom right like so:

.box {
    position:relative;
}
.bet_time {
    position:absolute;
    bottom:0;
    right:0;
}

The way this works is that absolutely positioned elements are always positioned with respect to the first relatively positioned parent element, or the window. Because we set the box's position to relative, .bet_time positions its right edge to the right edge of .box and its bottom edge to the bottom edge of .box

Delete Dan from employee.data - No need to manage a new data.frame.

employee.data <- subset(employee.data, name!="Dan")

With some error catching. Specifically, most of the functions presented require $end to exist, when in fact in my case I needed it to be optional. Use this is $end is optional, and evaluate for FALSE if $start doesn't exist at all:

function get_string_between( $string, $start, $end ){
    $string = " " . $string;
    $start_ini = strpos( $string, $start );
    $end = strpos( $string, $end, $start+1 );
    if ($start && $end) {
        return substr( $string, $start_ini + strlen($start), strlen( $string )-( $start_ini + $end ) );
    } elseif ( $start && !$end ) {
        return substr( $string, $start_ini + strlen($start) );
    } else {
        return FALSE;
    }

}

Try prepending the doublequote with a backslash in your expresssion:

sed 's/\"//g' [file name]

A lot of the answers suggest you need to return a collection of some sort, like a dictionary or a list. You could leave off the extra syntax and just write out the return values, comma-separated. Note: this technically returns a tuple.

def f():
    return True, False
x, y = f()
print(x)
print(y)

gives:

True
False

UPDATE: This is no longer necessary with Python3.4. It installs pip3 as part of the stock install.

I ended up posting this same question on the python mailing list, and got the following answer:

# download and install setuptools
curl -O https://bootstrap.pypa.io/ez_setup.py
python3 ez_setup.py
# download and install pip
curl -O https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py

Which solved my question perfectly. After adding the following for my own:

cd /usr/local/bin
ln -s ../../../Library/Frameworks/Python.framework/Versions/3.3/bin/pip pip

So that I could run pip directly, I was able to:

# use pip to install
pip install pyserial

or:

# Don't want it?
pip uninstall pyserial

For those who's working with latest webpack and has options property on there configuration. You cannot use query and options at the same time. You will get this error if both is present

Error: Provided options and query in use

Instead, add new property to options name generatorOpts, then add the property compact under it.

loaders: [
   { test: /\.js$/, loader: 'babel', option: { generatorOpts: { compact: false } } }
]

And for those who's working with next (like me). You need to do something like this

config.module.rules.filter((rule) => rule.use && rule.use.loader === 'next-babel-loader')
.map((loader) => {
    loader.use.options.generatorOpts = { compact: false };
    return loader;
});

Singleton scope in spring means single instance in a Spring context ..
Spring container merely returns the same instance again and again for subsequent calls to get the bean.


And spring doesn't bother if the class of the bean is coded as singleton or not , in fact if the class is coded as singleton whose constructor as private, Spring use BeanUtils.instantiateClass (javadoc here) to set the constructor to accessible and invoke it.

Alternatively, we can use a factory-method attribute in bean definition like this

    <bean id="exampleBean" class="example.Singleton"  factory-method="getInstance"/>

As already explained by the other contributers, you could print out the counter and then replace the return with a break statement.

N = int(input("enter a positive integer:"))
counter = 1
while (N > 0):
    counter = counter * N
    N = N - 1
    print(counter)
    break

Hope this coding will helps you :)

plot(x,y,xaxt = 'n')

axis(side=1,at=c(1,20,30,50),labels=c("1975","1980","1985","1990"))

In my case, the .git/config file was created not in my $HOME directory, but inside my repository on .git/config.lock

Deleting the file fixed the problem. The file is created, when I switch branches with git checkout -f branchname and files from a recently created submodule were overwritten by git checkout.

$ git branch --set-upstream-to=origin/branchname
error: could not lock config file .git/config: File exists
error: Unable to write upstream branch configuration
hint: 
hint: After fixing the error cause you may try to fix up
hint: the remote tracking information by invoking

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

you could also go to Hardware -> reboot, then Hardware -> Home, and click on your App

Only one suggestion:-

Read SOA Concepts, Technology and Design by Thomas Erl.

It has very beautifully given the details about SOA in plain English and with case studies.

So I have faced the same problem when trying to start apache service and I would like to share my solutions with you. Here is some notes about services or programs that may use port 80:

1. Skype: skype uses port 80/443 by default. You can change this from tools->options-> advanced->connections and uncheck the checkbox "use port 80 and 443 for addtional incoming connections".
2. IIS: IIS uses port 80 be default so you need to shut down it. You can use the following two commands net stop w3svc net stop iisadmin
3. SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.

These options work great with me and I can start apache service without errors.

The other option is to change apache listen port from httpd.conf and set another port number.

Hope this solution helps anyone who face the same problem again.

I did it like this in Internet Explorer.

function getWindowRelativeOffset(parentWindow, elem) {
    var offset = {
        left : 0,
        top : 0
    };
    // relative to the target field's document
    offset.left = elem.getBoundingClientRect().left;
    offset.top = elem.getBoundingClientRect().top;
    // now we will calculate according to the current document, this current
    // document might be same as the document of target field or it may be
    // parent of the document of the target field
    var childWindow = elem.document.frames.window;
    while (childWindow != parentWindow) {
        offset.left = offset.left + childWindow.frameElement.getBoundingClientRect().left;
        offset.top = offset.top + childWindow.frameElement.getBoundingClientRect().top;
        childWindow = childWindow.parent;
    }

    return offset;
};

=================== you can call it like this

getWindowRelativeOffset(top, inputElement);

I focus on IE only as per my focus but similar things can be done for other browsers.

I had this error because I didn't understand the difference between angular.module('myApp', []) and angular.module('myApp').

This creates the module 'myApp' and overwrites any existing module named 'myApp':

angular.module('myApp', [])

This retrieves an existing module 'myApp':

angular.module('myApp')

I had been overwriting my module in another file, using the first call above which created another module instead of retrieving as I expected.

More detail here: https://docs.angularjs.org/guide/module

list_ = list(range(9)) print(list_[1::2])

just for fun, valid rectangles and assuming that m[0] exists

>>> m = [[1,2,3],[4,5,6],[7,8,9]]
>>> [[row[i] for row in m] for i in range(len(m[0]))]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

I needed something compatible with the output of a dense layer from Tensorflow.

The solution from @desertnaut does not work in this case because I have batches of data. Therefore, I came with another solution that should work in both cases:

def softmax(x, axis=-1):
    e_x = np.exp(x - np.max(x)) # same code
    return e_x / e_x.sum(axis=axis, keepdims=True)

Results:

logits = np.asarray([
    [-0.0052024,  -0.00770216,  0.01360943, -0.008921], # 1
    [-0.0052024,  -0.00770216,  0.01360943, -0.008921]  # 2
])

print(softmax(logits))

#[[0.2492037  0.24858153 0.25393605 0.24827873]
# [0.2492037  0.24858153 0.25393605 0.24827873]]

You have to check on this.

HTML

<button id="saveActionId"> Save </button>

manifest.json

  "permissions": [
    "activeTab",
    "tabs"
   ]

JavaScript
The below code will save all the urls of active window into JSON object as part of button click.

var saveActionButton = document.getElementById('saveActionId');
saveActionButton.addEventListener('click', function() {
    myArray = [];
    chrome.tabs.query({"currentWindow": true},  //{"windowId": targetWindow.id, "index": tabPosition});
    function (array_of_Tabs) {  //Tab tab
        arrayLength = array_of_Tabs.length;
        //alert(arrayLength);
        for (var i = 0; i < arrayLength; i++) {
            myArray.push(array_of_Tabs[i].url);
        }
        obj = JSON.parse(JSON.stringify(myArray));
    });
}, false);

@param won't affect the number. It's just for making javadocs.

Since Hibernate ORM 5.2.10, you can do it likee this:

Object unproxiedEntity = Hibernate.unproxy(proxy);

Before Hibernate 5.2.10. the simplest way to do that was to use the unproxy method offered by Hibernate internal PersistenceContext implementation:

Object unproxiedEntity = ((SessionImplementor) session)
                         .getPersistenceContext()
                         .unproxy(proxy);

I don't think this has been mentioned yet, but you could also use Powermockito:

Given:

package com.foo.service.impl;

public class FooServiceImpl {

    public void doSomeFooStuff() {
        System.getenv("FOO_VAR_1");
        System.getenv("FOO_VAR_2");
        System.getenv("FOO_VAR_3");

        // Do the other Foo stuff
    }
}

You could do the following:

package com.foo.service.impl;

import static org.mockito.Mockito.when;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static org.powermock.api.mockito.PowerMockito.verifyStatic;

import org.junit.Beforea;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.MockitoAnnotations;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PrepareForTest(FooServiceImpl.class)
public class FooServiceImpTest {

    @InjectMocks
    private FooServiceImpl service;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);

        mockStatic(System.class);  // Powermock can mock static and private methods

        when(System.getenv("FOO_VAR_1")).thenReturn("test-foo-var-1");
        when(System.getenv("FOO_VAR_2")).thenReturn("test-foo-var-2");
        when(System.getenv("FOO_VAR_3")).thenReturn("test-foo-var-3");
    }

    @Test
    public void testSomeFooStuff() {        
        // Test
        service.doSomeFooStuff();

        verifyStatic();
        System.getenv("FOO_VAR_1");
        verifyStatic();
        System.getenv("FOO_VAR_2");
        verifyStatic();
        System.getenv("FOO_VAR_3");
    }
}

use range, or DateDiff function

 select * from test 
 where date between '03/19/2014' and '03/19/2014 23:59:59'

or

 select * from test 
 where datediff(day, date, '03/19/2014') = 0

Other options are:

1. If you have control over the database schema, and you don't need the time data, take it out.

2. or, if you must keep it, add a computed column attribute that has the time portion of the date value stripped off...

Alter table Test Add DateOnly As DateAdd(day, datediff(day, 0, date), 0)

or, in more recent versions of SQL Server...

Alter table Test Add DateOnly As Cast(DateAdd(day, datediff(day, 0, date), 0) as Date)

then, you can write your query as simply:

select * from test 
where DateOnly = '03/19/2014'

cd "$(dirname "${BASH_SOURCE[0]}")"

All the solutions here failed to work on my VS2013, however I put the #define _CRT_SECURE_NO_WARNINGS in the stdafx.h just before the #pragma once and all warnings were suppressed. Note: I only code for prototyping purposes to support my research so please make sure you understand the implications of this method when writing your code.

Hope this helps

Also, you might want to take a look at NetworkX

This solution is similar to the one given by Dominic Watson, which uses $validators and is the one I like best. The only changes are that you can watch an expression.

$validators A collection of validators that are applied whenever the model value changes. The key value within the object refers to the name of the validator while the function refers to the validation operation. The validation operation is provided with the model value as an argument and must return a true or false value depending on the response of that validation

from https://code.angularjs.org/1.3.15/docs/api/ng/type/ngModel.NgModelController

I'm using angular 1.3. My directive looks something like this

angular.module('app').directive("passwordConfirm", function() {
    "use strict";
    return {
        require : "ngModel",
        restrict : "A",
        scope : {
            //We will be checking that our input is equals to this expression
            passwordConfirm : '&'
        },
        link : function(scope, element, attrs, ctrl) {
            //The actual validation
            function passwordConfirmValidator(modelValue, viewValue) {
                return modelValue == scope.passwordConfirm();
            }
            //Register the validaton when this input changes
            ctrl.$validators.passwordConfirm = passwordConfirmValidator;
            //Also validate when the expression changes
            scope.$watch(scope.passwordConfirm, ctrl.$validate);
        }
    };
});

To use it

<input type="password" ng-model="user.password"/>
<input type="password" ng-model="user.confirmPassword"

Download the Python3.6 tgz file from the official website (eg. Python-3.6.6.tgz)
Unpack it with tar -xvzf Python-3.6.6.tgz
cd Python-3.6.6
run ./configure
run make altinstall to install it (install vs altinstall explanation here 

setting up python3.6 virtual environment for tensorflow

If you are using jupyter notebook or jupyter lab this can be helpful to choose the right virtual environment

python -m venv projectname
source projectname/bin/activate
pip install ipykernel
ipython kernel install --user --name=projectname

At this point, you can start jupyter, create a new notebook and select the kernel that lives inside your environment.

Hope this helps

Use ==:

pip install django_modeltranslation==0.4.0-beta2

Here is how I do a Subview on iOS in Swift -

class CustomSubview : UIView {

    init() {
        super.init(frame: UIScreen.mainScreen().bounds);

        let windowHeight : CGFloat = 150;
        let windowWidth  : CGFloat = 360;

        self.backgroundColor = UIColor.whiteColor();
        self.frame = CGRectMake(0, 0, windowWidth, windowHeight);
        self.center = CGPoint(x: UIScreen.mainScreen().bounds.width/2, y: 375);

        //for debug validation
        self.backgroundColor = UIColor.grayColor();
        print("My Custom Init");

        return;
    }

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

There's a workaround to achieve it.

1. First, bind your iframe to a target page with relative url. The browsers will treat the site in iframe the same domain with your website.

2. In your web server, using a rewrite module to redirect request from the relative url to absolute url. If you use IIS, I recommend you check on IIRF module.

If you prefer immutable data objects, or if you just dont want to be destructive to the input list, you can use Guava's predicates.

ImmutableList.copyOf(Iterables.filter(tourists, Predicates.notNull()))

Probably all your answers are better, but - just to be complete on the choice of options - I wanted to remind about old, similar method used for years:

SrvAny (installed by InstSrv)

as described here: https://docs.microsoft.com/en-us/troubleshoot/windows-client/deployment/create-user-defined-service

Look here for the answer by TheMattster. I implemented it and it worked like a charm. In a nutshell, his solution suggests to add the COM dll as a resource to the project (so now it compiles into the project's dll), and upon the first run write it to a file (i.e. the dll file I wanted there in the first place).

The following is taken from his answer.

Step 1) Add the DLL as a resource (below as "Resources.DllFile"). To do this open project properties, select the resources tab, select "add existing file" and add the DLL as a resource.

Step 2) Add the name of the DLL as a string resource (below as "Resources.DllName").

Step 3) Add this code to your main form-load:

if (!File.Exists(Properties.Resources.DllName))
{
    var outStream = new StreamWriter(Properties.Resources.DllName, false);
    var binStream = new BinaryWriter(outStream.BaseStream);
    binStream.Write(Properties.Resources.DllFile);
    binStream.Close();
}

My problem was that not only I had to use the COM dll in my project, I also had to deploy it with my app using ClickOnce, and without being able to add reference to it in my project the above solution is practically the only one that worked.

if ( $('#myfav').children().length > 0 ) {
     // do something
}

This should work. The children() function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.

Well one of the option is to goto your workspace, your project folder, then bin copy and paste the log4j properites file. it would be better to paste the file also in source folder.

Now you may want to know from where to get this file, download smslib, then extract it, then smslib->misc->log4j sample configuration -> log4j here you go.

This what helped,me so just wanted to know.

If you're using latest spring boot (with jdbc starter and Hikari) you'll run into: java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName. To solve this:

1. In your application.properties:

datasource.oracle.url=youroracleurl

2. In your application define as bean (@Primary is mandatory!):

@Bean
@Primary
@ConfigurationProperties("datasource.oracle")
public DataSourceProperties getDatasourceProperties() {
    return new DataSourceProperties();
}

@Bean
@ConfigurationProperties("datasource.oracle")
public DataSource getDatasource() {
    return getDatasourceProperties().initializeDataSourceBuilder()
           .username("username")
           .password("password")
           .build();
}

Some time ago I've created generic Java library which can be used to take pictures with a PC webcam. The API is very simple, not overfeatured, can work standalone, but also supports additional webcam drivers like OpenIMAJ, JMF, FMJ, LTI-CIVIL, etc, and some IP cameras.

Link to the project is https://github.com/sarxos/webcam-capture

Example code (take picture and save in test.jpg):

Webcam webcam = Webcam.getDefault();
webcam.open();
BufferedImage image = webcam.getImage();
ImageIO.write(image, "JPG", new File("test.jpg"));

It is also available in Maven Central Repository or as a separate ZIP which includes all required dependencies and 3rd party JARs.

I solved my problem by running below command

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

You can do base64 encoding and decoding with simple javascript.

    $("input").keyup(function () {
     var value = $(this).val(),
         hash = Base64.encode(value);
     $(".test").html(hash);

     var decode = Base64.decode(hash);

     $(".decode").html(decode);
 });

var Base64={_keyStr:"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",encode:function(e){var t="";var n,r,i,s,o,u,a;var f=0;e=Base64._utf8_encode(e);while(f<e.length){n=e.charCodeAt(f++);r=e.charCodeAt(f++);i=e.charCodeAt(f++);s=n>>2;o=(n&3)<<4|r>>4;u=(r&15)<<2|i>>6;a=i&63;if(isNaN(r)){u=a=64}else if(isNaN(i)){a=64}t=t+this._keyStr.charAt(s)+this._keyStr.charAt(o)+this._keyStr.charAt(u)+this._keyStr.charAt(a)}return t},decode:function(e){var t="";var n,r,i;var s,o,u,a;var f=0;e=e.replace(/[^A-Za-z0-9+/=]/g,"");while(f<e.length){s=this._keyStr.indexOf(e.charAt(f++));o=this._keyStr.indexOf(e.charAt(f++));u=this._keyStr.indexOf(e.charAt(f++));a=this._keyStr.indexOf(e.charAt(f++));n=s<<2|o>>4;r=(o&15)<<4|u>>2;i=(u&3)<<6|a;t=t+String.fromCharCode(n);if(u!=64){t=t+String.fromCharCode(r)}if(a!=64){t=t+String.fromCharCode(i)}}t=Base64._utf8_decode(t);return t},_utf8_encode:function(e){e=e.replace(/rn/g,"n");var t="";for(var n=0;n<e.length;n++){var r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r)}else if(r>127&&r<2048){t+=String.fromCharCode(r>>6|192);t+=String.fromCharCode(r&63|128)}else{t+=String.fromCharCode(r>>12|224);t+=String.fromCharCode(r>>6&63|128);t+=String.fromCharCode(r&63|128)}}return t},_utf8_decode:function(e){var t="";var n=0;var r=c1=c2=0;while(n<e.length){r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r);n++}else if(r>191&&r<224){c2=e.charCodeAt(n+1);t+=String.fromCharCode((r&31)<<6|c2&63);n+=2}else{c2=e.charCodeAt(n+1);c3=e.charCodeAt(n+2);t+=String.fromCharCode((r&15)<<12|(c2&63)<<6|c3&63);n+=3}}return t}}

// Define the string
var string = 'Hello World!';

// Encode the String
var encodedString = Base64.encode(string);
console.log(encodedString); // Outputs: "SGVsbG8gV29ybGQh"

// Decode the String
var decodedString = Base64.decode(encodedString);
console.log(decodedString); // Outputs: "Hello World!"</script></div>

This is implemented in this Base64 encoder decoder

Try the following, no extra headers

wget -qO- www.google.com

Note the trailing -. This is part of the normal command argument for -O to cat out to a file, but since we don't use > to direct to a file, it goes out to the shell. You can use -qO- or -qO -.

It works for me on macOS Majave

You can do a few simple steps:

1) open terminal

2) sudo nano /.bash_profile

3) add your aliases, as example:

# some aliases
alias ll='ls -alF'
alias la='ls -A'
alias eb="sudo nano ~/.bash_profile && source ~/.bash_profile"
#docker aliases
alias d='docker'
alias dc='docker-compose'
alias dnax="docker rm $(docker ps -aq)"
#git aliases
alias g='git'
alias new="git checkout -b"
alias last="git log -2"
alias gg='git status'
alias lg="git log --pretty=format:'%h was %an, %ar, message: %s' --graph"
alias nah="git reset --hard && git clean -df"
alias squash="git rebase -i HEAD~2"

4) source /.bash_profile

Done. Use and enjoy!

The 'else' statement is mandatory. You can do stuff like this :

>>> b = True
>>> a = 1 if b else None
>>> a
1
>>> b = False
>>> a = 1 if b else None
>>> a
>>> 

EDIT:

Or, depending of your needs, you may try:

>>> if b: print(a)

You may also use this.Resources["mykey"]. I guess that is not much better than your own suggestion.

_countof(my_array) in MSVC

I can thing of only one case: the array contains elements that are of different derived types of the type of the array.

Elements of an array in C++ are objects, not pointers, so you cannot have derived type object as an element.

And like mentioned above, sizeof(my_array) (like _countof() as well) will work just in the scope of array definition.

I would recommend you to change Status cache of the Overlays.

Settings -> Icon Overlays -> Status cache

Maybe this would help to reinitialise the cache.

Be sure touse the latest version of Tortoise.

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

Per the docs:

If you manually code a script tag in HTML to load a script with an anonymous define() call, this error can occur.

Also seen if you manually code a script tag in HTML to load a script that has a few named modules, but then try to load an anonymous module that ends up having the same name as one of the named modules in the script loaded by the manually coded script tag.

Finally, if you use the loader plugins or anonymous modules (modules that call define() with no string ID) but do not use the RequireJS optimizer to combine files together, this error can occur. The optimizer knows how to name anonymous modules correctly so that they can be combined with other modules in an optimized file.

To avoid the error:

• Be sure to load all scripts that call define() via the RequireJS API. Do not manually code script tags in HTML to load scripts that have define() calls in them.

• If you manually code an HTML script tag, be sure it only includes named modules, and that an anonymous module that will have the same name as one of the modules in that file is not loaded.

• If the problem is the use of loader plugins or anonymous modules but the RequireJS optimizer is not used for file bundling, use the RequireJS optimizer.

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

Simply do this:

<object data="resume.pdf" type="application/pdf" width="100%" height="800px"> 
  <p>It appears you don't have a PDF plugin for this browser.
   No biggie... you can <a href="resume.pdf">click here to
  download the PDF file.</a></p>  
</object>

To remove the scrollbar add the following CSS:

select[multiple] {
    overflow-y: auto;
}

Here's a snippet:

select[multiple] {_x000D_
  overflow-y: auto;_x000D_
}

<select>_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>_x000D_
_x000D_
<select multiple size="3">_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>

Try this -

plt.xticks(rotation=90)

Few years later, want to suggest just for this: https://github.com/casey/just

action v1 v2=default:
    @echo 'take action on {{v1}} and {{v2}}...'

here the problem is model binding if you specify a class then the model binding can understand it during the post if it an integer or string then you have to specify the [FromBody] to bind it properly.

make the following changes in FormMethod

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){

}

and inside your home controller for binding the string you should specify [FromBody]

using System.Web.Http;
[HttpPost]
public FileStreamResult myMethod([FromBody]string id)
{
     // Set a local variable with the incoming data
     string str = id;

}

FromBody is available in System.Web.Http. make sure you have the reference to that class and added it in the cs file.

Updating @tangy answer from above to the current version of scikit-learn: 0.23.2 (StratifiedShuffleSplit documentation).

from sklearn.model_selection import StratifiedShuffleSplit

n_splits = 1  # We only want a single split in this case
sss = StratifiedShuffleSplit(n_splits=n_splits, test_size=0.25, random_state=0)

for train_index, test_index in sss.split(X, y):
    X_train, X_test = X[train_index], X[test_index]
    y_train, y_test = y[train_index], y[test_index]

It appears to be a known issue.

Many IN queries can be re-written as (left outer) joins and an IS (NOT) NULL of some sort. for example

SELECT * FROM FOO WHERE ID IN (SELECT ID FROM FOO2)

can be re-written as

SELECT FOO.* FROM FOO JOIN FOO2 ON FOO.ID=FOO2.ID

or

SELECT * FROM FOO WHERE ID NOT IN (SELECT ID FROM FOO2)

can be

SELECT FOO.* FROM FOO 
LEFT OUTER JOIN FOO2 
ON FOO.ID=FOO2.ID WHERE FOO.ID IS NULL

This assumes SQL Server 2005+ and your definition of "last" is the max PK for a given email

WITH CTE AS
(
SELECT ID, 
       Email, 
       ProductName, 
       ProductModel, 
       ROW_NUMBER() OVER (PARTITION BY Email ORDER BY ID DESC) AS RowNumber 
FROM   Products
)
SELECT ID, 
       Email, 
       ProductName, 
       ProductModel
FROM CTE 
WHERE RowNumber = 1

If you're using MSTest, which originally didn't have an ExpectedException attribute, you could do this:

try 
{
    SomeExceptionThrowingMethod()
    Assert.Fail("no exception thrown");
}
catch (Exception ex)
{
    Assert.IsTrue(ex is SpecificExceptionType);
}

Don't reinvent the wheel. Use json-framework or something similar.

If you do decide to use json-framework, here's how you would parse a JSON string into an NSDictionary:

SBJsonParser* parser = [[[SBJsonParser alloc] init] autorelease];
// assuming jsonString is your JSON string...
NSDictionary* myDict = [parser objectWithString:jsonString];

// now you can grab data out of the dictionary using objectForKey or another dictionary method

@Html.Partial("NameOfPartialView")

Lot of answers seem to be overkill. FOR ME , this works

 <a ng-href="#" ng-click="$event.preventDefault();vm.questionContainer($index)">{{question.Verbiage}}</a>

@Override on interfaces actually are helpful, because you will get warnings if you change the interface.

EDIT: http://jsfiddle.net/nCFGL/223/ My Example.

You should be able to like follows:

var pieData = [{
    value: 30,
    color: "#F38630",
    label: 'Sleep',
    labelColor: 'white',
    labelFontSize: '16'
  },
  ...
];

I want to put here some information for those, who do separately drawing of picture and moving -zooming it.

This may be useful when you want to store zooms and position of viewport.

Here is drawer:

function redraw_ctx(){
   self.ctx.clearRect(0,0,canvas_width, canvas_height)
   self.ctx.save()
   self.ctx.scale(self.data.zoom, self.data.zoom) // 
   self.ctx.translate(self.data.position.left, self.data.position.top) // position second
   // Here We draw useful scene My task - image:
   self.ctx.drawImage(self.img ,0,0) // position 0,0 - we already prepared
   self.ctx.restore(); // Restore!!!
}

Notice scale MUST be first.

And here is zoomer:

function zoom(zf, px, py){
    // zf - is a zoom factor, which in my case was one of (0.1, -0.1)
    // px, py coordinates - is point within canvas 
    // eg. px = evt.clientX - canvas.offset().left
    // py = evt.clientY - canvas.offset().top
    var z = self.data.zoom;
    var x = self.data.position.left;
    var y = self.data.position.top;

    var nz = z + zf; // getting new zoom
    var K = (z*z + z*zf) // putting some magic

    var nx = x - ( (px*zf) / K ); 
    var ny = y - ( (py*zf) / K);

    self.data.position.left = nx; // renew positions
    self.data.position.top = ny;   
    self.data.zoom = nz; // ... and zoom
    self.redraw_ctx(); // redraw context
    }

and, of course, we would need a dragger:

this.my_cont.mousemove(function(evt){
    if (is_drag){
        var cur_pos = {x: evt.clientX - off.left,
                       y: evt.clientY - off.top}
        var diff = {x: cur_pos.x - old_pos.x,
                    y: cur_pos.y - old_pos.y}

        self.data.position.left += (diff.x / self.data.zoom);  // we want to move the point of cursor strictly
        self.data.position.top += (diff.y / self.data.zoom);

        old_pos = cur_pos;
        self.redraw_ctx();

    }


})

A little modification of @Mirek Rusin answer and now you can detect multitouch swipes. This code is on Kotlin:

}

override fun onTouch(v: View, event: MotionEvent): Boolean {
    if (event.pointerCount > fingersCount) {
        fingersCount = event.pointerCount
    }
    return gestureDetector.onTouchEvent(event)
}

private inner class GestureListener : SimpleOnGestureListener() {

                        onGesture.invoke(gesture)
                    }
                }
                resetFingers()
            }
            result = true

        } catch (exception: Exception) {
            exception.printStackTrace()
        }

        return result
    }
}}

Where Gesture.SWIPE_RIGHT and others are unique integer indentificator of gesture that I`m using to detect kind of gesture later in my activity:

rootView?.setOnTouchListener(OnSwipeTouchListener(this, {
    gesture -> log(Gesture.parseName(this, gesture))
}))

So you see gesture here is an integer variable that holds value I have passed before.

In Rails you can use:

{'g'=> 'a', 2 => {'v' => 'b', 'x' => { 'z' => 'c'}}}.deep_symbolize_keys!

Converts to:

{:g=>"a", 2=>{:v=>"b", :x=>{:z=>"c"}}}

The solution I use is the following:

<input list="answers" id="answer">
<datalist id="answers">
  <option data-value="42" value="The answer">
</datalist>

Then access the value to be sent to the server using JavaScript like this:

var shownVal = document.getElementById("answer").value;
var value2send = document.querySelector("#answers option[value='"+shownVal+"']").dataset.value;

Hope it helps.

I modified rushidesai1's answer to include a working example.

i think the most proper way is to use the same piece of code angular use when doing a "get" request using you $httpParamSerializer will have to inject it to your controller so you can simply do the following without having to use Jquery at all , $http.post(url,$httpParamSerializer({param:val}))

app.controller('ctrl',function($scope,$http,$httpParamSerializer){
  $http.post(url,$httpParamSerializer({param:val,secondParam:secondVal}));
}

There are a few techniques for "preloading" here: http://paulirish.com/2009/fighting-the-font-face-fout/

Mostly tricking the browser into downloading the file as fast as possible..

You can also deliver it as a data-uri, which helps a lot. and also you could hide the page content and show it when its ready.

In MomentJs We can declare it like :

   const start = moment().format('YYYY-MM-DD 00:00:01');
   const end = moment().format('YYYY-MM-DD 23:59:59');

Dealing with markup in floats is a non trivial task. In the English/American notation you format one thousand plus 46*10-2:

1,000.46

But in Germany you would change comma and point:

1.000,46

This makes it really hard guessing the right number in multi-language applications.
I strongly suggest using Zend_Measure of the Zend Framework for this task. This component will parse the string to a float by the users language.

I don't think you'll ever get a definitive solution for this, the operating system isn't necessarily going to tell you if the file is open or not.

You might get some mileage out of java.nio.channels.FileLock, although the javadoc is loaded with caveats.

The easiest way is to remove it from the tab index all together:

$('#control').find('input[readonly]').each(function () {
    $(this).attr('tabindex', '-1');
});

I already use this on a couple of forms.

Declaring inside the loop limits the scope of the respective variable. It all depends on the requirement of the project on the scope of the variable.

if (str.toLowerCase().indexOf("yes") >= 0)

Or,

if (/yes/i.test(str))

You could use the @Rule annotation with ExpectedException, like this:

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

@Test
public void shouldThrowRuntimeExceptionWhenEmployeeIDisNull() throws Exception {
    expectedEx.expect(RuntimeException.class);
    expectedEx.expectMessage("Employee ID is null");

    // do something that should throw the exception...
    System.out.println("=======Starting Exception process=======");
    throw new NullPointerException("Employee ID is null");
}

Note that the example in the ExpectedException docs is (currently) wrong - there's no public constructor, so you have to use ExpectedException.none().

Using standard library:

Assuming that your implementation meaningfully supports SEEK_END:

fseek(f, 0, SEEK_END); // seek to end of file
size = ftell(f); // get current file pointer
fseek(f, 0, SEEK_SET); // seek back to beginning of file
// proceed with allocating memory and reading the file

Linux/POSIX:

You can use stat (if you know the filename), or fstat (if you have the file descriptor).

Here is an example for stat:

#include <sys/stat.h>
struct stat st;
stat(filename, &st);
size = st.st_size;

Win32:

You can use GetFileSize or GetFileSizeEx.

You can style input[type=text] differently depending on whether or not the input has text by styling the placeholder. This is not an official standard at this point but has wide browser support, though with different prefixes:

input[type=text] {
    color: red;
}
input[type=text]:-moz-placeholder {
    color: green;
}
input[type=text]::-moz-placeholder {
    color: green;
}
input[type=text]:-ms-input-placeholder {
    color: green;
}
input[type=text]::-webkit-input-placeholder {
    color: green;
}

Example: http://fiddlesalad.com/scss/input-placeholder-css

Why not just git reset --soft <branch_name>?

Demonstration:

mkdir myrepo; cd myrepo; git init
touch poem; git add poem; git commit -m 'add poem'  # first commit
git branch original
echo bananas > poem; git commit -am 'change poem'  # second commit
echo are tasty >> poem  # unstaged change
git reset --soft original

Result:

$ git diff --cached
diff --git a/poem b/poem

One thing to note though, is that the current branch changes to original. You’re still left in the previous branch after the process, but can easily git checkout original, because it’s the same state. If you do not want to lose the previous HEAD, you should note the commit reference and do git branch -f <previous_branch> <commit> after that.

you can use getTime() and compare the returned long UTC values.

EDIT if you are sure you'll not have to deal with dates before 1970, not sure how it will behave in that case.

Using the idea of totem and zlangner, I have created a KnownTypeConverter that will be able to determine the most appropriate inheritor, while taking into account that json data may not have optional elements.

So, the service sends a JSON response that contains an array of documents (incoming and outgoing). Documents have both a common set of elements and different ones. In this case, the elements related to the outgoing documents are optional and may be absent.

In this regard, a base class Document was created that includes a common set of properties. Two inheritor classes are also created: - OutgoingDocument adds two optional elements "device_id" and "msg_id"; - IncomingDocument adds one mandatory element "sender_id";

The task was to create a converter that based on json data and information from KnownTypeAttribute will be able to determine the most appropriate class that allows you to save the largest amount of information received. It should also be taken into account that json data may not have optional elements. To reduce the number of comparisons of json elements and properties of data models, I decided not to take into account the properties of the base class and to correlate with json elements only the properties of the inheritor classes.

Data from the service:

{
    "documents": [
        {
            "document_id": "76b7be75-f4dc-44cd-90d2-0d1959922852",
            "date": "2019-12-10 11:32:49",
            "processed_date": "2019-12-10 11:32:49",
            "sender_id": "9dedee17-e43a-47f1-910e-3a88ff6bc258",
        },
        {
            "document_id": "5044a9ac-0314-4e9a-9e0c-817531120753",
            "date": "2019-12-10 11:32:44",
            "processed_date": "2019-12-10 11:32:44",
        }
    ], 
    "total": 2
}

Data models:

/// <summary>
/// Service response model
/// </summary>
public class DocumentsRequestIdResponse
{
    [JsonProperty("documents")]
    public Document[] Documents { get; set; }

    [JsonProperty("total")]

    public DateTime Date { get; set; }

    [JsonProperty("processed_date")]
    public DateTime ProcessedDate { get; set; } 
}

/// <summary>

public class OutgoingDocument : Document
{
    // this property is optional and may not be present in the service's json response
    [JsonProperty("device_id")]
    public string DeviceId { get; set; }

    // this property is optional and may not be present in the service's json response
    [JsonProperty("msg_id")]
    public string MsgId { get; set; }
}

/// <summary>

public class IncomingDocument : Document
{
    // this property is mandatory and is always populated by the service
    [JsonProperty("sender_sys_id")]
    public Guid SenderSysId { get; set; }
}

Converter:

public class KnownTypeConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return System.Attribute.GetCustomAttributes(objectType).Any(v => v is KnownTypeAttribute);
    }

            var notIgnoreProps = knownType.GetProperties(BindingFlags.Instance | BindingFlags.Public)
                .Where(p => !objectTypeProps.Contains(p.Name)
                            && p.CustomAttributes.All(a => a.AttributeType != typeof(JsonIgnoreAttribute) && a.AttributeType != typeof(System.Xml.Serialization.XmlIgnoreAttribute)));

            //  get serializable property names
            var jsonNameFields = notIgnoreProps.Select(prop =>
            {
                string jsonFieldName = null;
                CustomAttributeData jsonPropertyAttribute = prop.CustomAttributes.FirstOrDefault(a => a.AttributeType == typeof(JsonPropertyAttribute));
                if (jsonPropertyAttribute != null)
                {
                    // take the name of the json element from the attribute constructor
                    CustomAttributeTypedArgument argument = jsonPropertyAttribute.ConstructorArguments.FirstOrDefault();

                        jsonFieldName = (string)argument.Value;
                }
                // otherwise, take the name of the property
                if (string.IsNullOrEmpty(jsonFieldName))
                {
                    jsonFieldName = prop.Name;
                }

                return jsonFieldName;
            });


            HashSet<string> jKnownTypeKeys = new HashSet<string>(jsonNameFields);

            // by intersecting the sets of names we determine the most suitable inheritor
            int count = jObjectKeys.Intersect(jKnownTypeKeys).Count();

            if (count == jKnownTypeKeys.Count)
            {
                mostSuitableType = knownType;
                break;
            }

            if (count > countOfMaxMatchingProperties)
            {
                countOfMaxMatchingProperties = count;
                mostSuitableType = knownType;
            }
        }

        if (mostSuitableType != null)

            }
            return target;

        throw new SerializationException($"Could not serialize to KnownTypes and assign to base class {objectType} reference");

        jObjectReader.Culture = reader.Culture;
        jObjectReader.DateFormatString = reader.DateFormatString;
        jObjectReader.DateParseHandling = reader.DateParseHandling;
        jObjectReader.DateTimeZoneHandling = reader.DateTimeZoneHandling;
        jObjectReader.FloatParseHandling = reader.FloatParseHandling;

        jObjectReader.SupportMultipleContent = reader.SupportMultipleContent;
        return jObjectReader;
    }
}

PS: In my case, if no one inheritor has not been selected by converter (this can happen if the JSON data contains information only from the base class or the JSON data does not contain optional elements from the OutgoingDocument), then an object of the OutgoingDocument class will be created, since it is listed first in the list of KnownTypeAttribute attributes. At your request, you can vary the implementation of the KnownTypeConverter in this situation.

This is what Wikipedia says about finally clause:

More common is a related clause (finally, or ensure) that is executed whether an exception occurred or not, typically to release resources acquired within the body of the exception-handling block.

Let's dissect your program.

try {
    System.out.print(1);
    q();
}

So, 1 will be output into the screen, then q() is called. In q(), an exception is thrown. The exception is then caught by Exception y but it does nothing. A finally clause is then executed (it has to), so, 3 will be printed to screen. Because (in method q() there's an exception thrown in the finally clause, also q() method passes the exception to the parent stack (by the throws Exception in the method declaration) new Exception() will be thrown and caught by catch ( Exception i ), MyExc2 exception will be thrown (for now add it to the exception stack), but a finally in the main block will be executed first.

So in,

catch ( Exception i ) {
    throw( new MyExc2() );
} 
finally {
    System.out.print(2);
    throw( new MyExc1() );
}

A finally clause is called...(remember, we've just caught Exception i and thrown MyExc2) in essence, 2 is printed on screen...and after the 2 is printed on screen, a MyExc1 exception is thrown. MyExc1 is handled by the public static void main(...) method.

Output:

"132Exception in thread main MyExc1"

Lecturer is correct! :-)

In essence, if you have a finally in a try/catch clause, a finally will be executed (after catching the exception before throwing the caught exception out)

Another way to do this

find . -name *.xml -exec sed -i "s/4.6.0-SNAPSHOT/5.0.0-SNAPSHOT/" {} \;

Some help regarding the above command

The find will do the find for you on the current directory indicated by .

-name the name of the file in my case its pom.xml can give wild cards.

-exec execute

sed stream editor

-i ignore case

s is for substitute

/4.6.0.../ String to be searched

/5.0.0.../ String to be replaced

If you use ArrayList instead of list then also your problem wil be solved. In your code only modify List into ArrayList.

private List<Item> data;

Keep in mind this overwrites any ID that the element already has:

 $(".element").attr("id","SomeID");

The reason why addClass exists is because an element can have multiple classes, so you wouldn't want to necessarily overwrite the classes already set. But with most attributes, there is only one value allowed at any given time.

To restore menu bar visibility so that you don't press key Alt to make the menu bar visible and the menu bar remains visible all the time, see the setting below.

You inadvertently changed the value from "default" to "toggle", so restore the setting to "default" as shown below.

"window.menuBarVisibility": "default"

After poking around it looks like Kelsey is correct.

Just use a comma or something and split it when you want to consume it.

When the LinkButton Enabled property is false it just renders a standard hyperlink. When you right click any disabled hyperlink you don't get the option to open in anything.

try

lbnkVidTtile1.Enabled = true;

I'm sorry if I misunderstood. Could I just make sure that you understand the purpose of a LinkButton? It is to give the appearance of a HyperLink but the behaviour of a Button. This means that it will have an anchor tag, but there is JavaScript wired up that performs a PostBack to the page. If you want to link to another page then it is recommended here that you use a standard HyperLink control.

In this tutorial is explained how to consume a web api with C#, in this example a console application is used, but you can also use another web api to consume of course.

http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client

You should have a look at the HttpClient

HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/yourwebapi");

Make sure your requests ask for the response in JSON using the Accept header like this:

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

Now comes the part that differs from the tutorial, make sure you have the same objects as the other WEB API, if not, then you have to map the objects to your own objects. ASP.NET will convert the JSON you receive to the object you want it to be.

HttpResponseMessage response = client.GetAsync("api/yourcustomobjects").Result;
if (response.IsSuccessStatusCode)
{
    var yourcustomobjects = response.Content.ReadAsAsync<IEnumerable<YourCustomObject>>().Result;
    foreach (var x in yourcustomobjects)
    {
        //Call your store method and pass in your own object
        SaveCustomObjectToDB(x);
    }
}
else
{
    //Something has gone wrong, handle it here
}

please note that I use .Result for the case of the example. You should consider using the async await pattern here.

Sublime 3 for Windows:

Add comment tags -> CTRL + SHIFT + ;
The whole line becomes a comment line -> CTRL + ;

You could open a command prompt, CD to the Debug or Release folder, and type the name of your exe. When I suggest this to people they think it is a lot of work, but here are the bare minimum clicks and keystrokes for this:

• in Visual Studio, right click your project in Solution Explorer or the tab with the file name if you have a file in the solution open, and choose Open Containing Folder or Open in Windows Explorer
• in the resulting Windows Explorer window, double-click your way to the folder with the exe
• Shift-right-click in the background of the explorer window and choose Open Commmand Window here
• type the first letter of your executable and press tab until the full name appears
• press enter

I think that's 14 keystrokes and clicks (counting shift-right-click as two for example) which really isn't much. Once you have the command prompt, of course, running it again is just up-arrow, enter.

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

If you're going to be doing any sort of arithmetic operations in the DB (multiplying out billing rates and so on), you'll probably want a lot more precision than people here are suggesting, for the same reasons that you'd never want to use anything less than a double-precision floating point value in application code.

I may be wrong but it seems people seem to be going way off-topic for

i just need to know if the gps icon at the top of the screen is blinking (no actual fix)

That is easily done with

LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);
boolean gps_on = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);

To see if you have a solid fix, things get a little trickier:

public class whatever extends Activity {
    LocationManager lm;
    Location loc;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        
        lm = (LocationManager) getSystemService(LOCATION_SERVICE);
        loc = null;
        request_updates();        
    }

    private void request_updates() {
        if (lm.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
            // GPS is enabled on device so lets add a loopback for this locationmanager
            lm.requestLocationUpdates(LocationManager.GPS_PROVIDER,0, 0, locationListener);
        }      
    }

    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {
            // Each time the location is changed we assign loc
            loc = location;
        }

         // Need these even if they do nothing. Can't remember why.
         public void onProviderDisabled(String arg0) {}
         public void onProviderEnabled(String provider) {}
         public void onStatusChanged(String provider, int status, Bundle extras) {}
    };

Now whenever you want to see if you have fix?

if (loc != null){
    // Our location has changed at least once
    blah.....
}

If you want to be fancy you can always have a timeout using System.currentTimeMillis() and loc.getTime()

Works reliably, at least on an N1 since 2.1.

I've written a library that is up-to-date, since all the other answers are outdated:

https://github.com/flagbug/YoutubeExtractor

I had a lot of problems and errors to solve, some of the above answers helped, but what the final trick that made it work for me was: Go to your project, click properties.

Go to the Package/Publish Web tab and make sure the configuration is set to Release and Platform to All Platforms.

Last make sure that the "Items to deploy (applies to all deployment methods)" is set to "All files in this project folder"

It then worked fine for me.

the link to getdate: https://api.jqueryui.com/datepicker/#method-getDate

$("#datepicker").datepicker( 'getDate' );

I got this to finally work in a semi-automatic fashion without the use of scripts... but it does take up 3 cells to pull it off. Borrowing from a bit from previous answers, I start with a cell that has nothing more than =NOW() it in to show the time. For example, we'll put this into cell A1...

=NOW()

This function updates automatically every minute. In the next cell, put a pointer formula using the sheets own name to point to the previous cell. For example, we'll put this in A2...

='Sheet Name'!A1

Cell formatting aside, cell A1 and A2 should at this point display the same content... namely the current time.

And, the last cell is the part I'm borrowing from previous solutions using a regex expression to pull the fomula from the second cell and then strip out the name of the sheet from said formula. For example, we'll put this into cell A3...

=REGEXREPLACE(FORMULATEXT(A2),"='?([^']+)'?!.*","$1")

At this point, the resultant value displayed in A3 should be the name of the sheet.

From my experience, as soon as the name of the sheet is changed, the formula in A2 is immediately updated. However that's not enough to trigger A3 to update. But, every minute when cell A1 recalculates the time, the result of the formula in cell A2 is subsequently updated and then that in turn triggers A3 to update with the new sheet name. It's not a compact solution... but it does seem to work.

Depending on which style you want to set, you have to use different methods. TextAppearance stuff has its own setter, TypeFace has its own setter, background has its own setter, etc.

Your declaration is int ttTreeInsert(int value);

However, your definition/implementation is

ttTree::ttTreeInsert(int value)
{
}

Notice that the return type int is missing in the implementation. Instead it should be

int ttTree::ttTreeInsert(int value)
{
    return 1; // or some valid int
}

This can happen when you added Core Data to an existing project.
Check the:
<Name>/<Name>.xcdatamodeld/<Name>.xcdatamodel/contents
file.
This file contains an entry "sourceLanguage" that (by default) might have been set to "Swift". Change it to "Objective-C".

Copy-pasted from here: Incrementing a date in JavaScript

Three options for you:

Using just JavaScript's Date object (no libraries):

var today = new Date();
var tomorrow = new Date(today.getTime() + (24 * 60 * 60 * 1000));

Or if you don't mind changing the date in place (rather than creating a new date):

var dt = new Date();
dt.setTime(dt.getTime() + (24 * 60 * 60 * 1000));

Edit: See also Jigar's answer and David's comment below: var tomorrow = new Date(); tomorrow.setDate(tomorrow.getDate() + 1);

Using MomentJS:

var today = moment();
var tomorrow = moment(today).add(1, 'days');

(Beware that add modifies the instance you call it on, rather than returning a new instance, so today.add(1, 'days') would modify today. That's why we start with a cloning op on var tomorrow = ....)

Using DateJS, but it hasn't been updated in a long time:

var today = new Date(); // Or Date.today()
var tomorrow = today.add(1).day();
