What worked for me, using jQuery and tested in IE8, Chrome and Firefox, is:

$(window).bind("beforeunload",function(event) {
    if(hasChanged) return "You have unsaved changes";
});

It is important not to return anything if no prompt is required as there are differences between IE and other browser behaviours here.

For Spring Boot 2.1.0 and later you can use

mvn spring-boot:run -Dspring-boot.run.profiles=foo,bar

Slicing works (and is the preferred approach), but just an alternative if more operations are needed (but then converting to a list wouldn't hurt anyway):

>>> a = '123456789'
>>> b = bytearray(a)
>>> del b[3]
>>> b
bytearray(b'12356789')
>>> str(b)
'12356789'

Use a FULL OUTER JOIN:

select 
   a.col_a,
   a.col_b,
   b.col_c
from
   (select col_a,col_bfrom tab1) a
join 
   (select col_a,col_cfrom tab2) b 
on a.col_a= b.col_a

Blundell's first answer didn't work for me. However it showed me the right way. I have done the same thing like this:

> for i in `git ls-files -i --exclude-from=.gitignore`; do git rm --cached $i; done
> git commit -m 'Removed all files that are in the .gitignore'
> git push origin master

I advise you to check the files to be deleted first by running the below statement:

git ls-files -i --exclude-from=.gitignore

I was using a default .gitignore file for visual studio and I noticed that it was removing all log and bin folders in the project which was not my intended action.

void myFunc(char* str, char c)
{
    char* ptr;
    int index;

    ptr = strchr(str, c);
    if (ptr == NULL)
    {
        printf("Character not found\n");
        return;
    }

    index = ptr - str;

    printf("The index is %d\n", index);
    ASSERT(str[index] == c);  // Verify that the character at index is the one we want.
}

This code is currently untested, but it demonstrates the proper concept.

Since the release of iOS 8, UIAlertView is now deprecated; UIAlertController is the replacement.

Here is a sample of how it looks in Swift:

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
let alertAction = UIAlertAction(title: "OK!", style: UIAlertActionStyle.default)
{
    (UIAlertAction) -> Void in
}
alert.addAction(alertAction)
present(alert, animated: true)
{
    () -> Void in
}

As you can see, the API allows us to implement callbacks for both the action and when we are presenting the alert, which is quite handy!

Updated for Swift 4.2

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: .alert)
let alertAction = UIAlertAction(title: "OK!", style: .default)
        {
            (UIAlertAction) -> Void in
        }
        alert.addAction(alertAction)
        present(alert, animated: true)
        {
            () -> Void in
        }

This question is a old one but it can help for others too.

Try this :

    li.setBackgroundColor(getResources().getColor(R.color.blue));

    or

    li.setBackgroundColor(getResources().getColor(android.R.color.red));

    or

    li.setBackgroundColor(Color.rgb(226, 11, 11));


    or
    li.setBackgroundColor(Color.RED)

About the memory layout

As a side note, the problem with the Dreaded Diamond is that the base class is present multiple times. So with regular inheritance, you believe you have:

  A
 / \
B   C
 \ /
  D

But in the memory layout, you have:

A   A
|   |
B   C
 \ /
  D

This explain why when call D::foo(), you have an ambiguity problem. But the real problem comes when you want to use a member variable of A. For example, let's say we have:

class A
{
    public :
       foo() ;
       int m_iValue ;
} ;

When you'll try to access m_iValue from D, the compiler will protest, because in the hierarchy, it'll see two m_iValue, not one. And if you modify one, say, B::m_iValue (that is the A::m_iValue parent of B), C::m_iValue won't be modified (that is the A::m_iValue parent of C).

This is where virtual inheritance comes handy, as with it, you'll get back to a true diamond layout, with not only one foo() method only, but also one and only one m_iValue.

What could go wrong?

Imagine:

• A has some basic feature.
• B adds to it some kind of cool array of data (for example)
• C adds to it some cool feature like an observer pattern (for example, on m_iValue).
• D inherits from B and C, and thus from A.

With normal inheritance, modifying m_iValue from D is ambiguous and this must be resolved. Even if it is, there are two m_iValues inside D, so you'd better remember that and update the two at the same time.

With virtual inheritance, modifying m_iValue from D is ok... But... Let's say that you have D. Through its C interface, you attached an observer. And through its B interface, you update the cool array, which has the side effect of directly changing m_iValue...

As the change of m_iValue is done directly (without using a virtual accessor method), the observer "listening" through C won't be called, because the code implementing the listening is in C, and B doesn't know about it...

Conclusion

If you're having a diamond in your hierarchy, it means that you have 95% probability to have done something wrong with said hierarchy.

You cannot cause the user's browser to send email silently. That would be a horrible security problem as any website could use their system as a spam relay and/or harvest their email address.

You need to make an HTTP request to a server side process (written in the language of your choice) which sends the mail from your server.

For array type Please try this one.

 List<MyStok> myDeserializedObjList = (List<MyStok>)Newtonsoft.Json.JsonConvert.DeserializeObject(sc), typeof(List<MyStok>));

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

I think this is possible in one case

1.Some of the native music players in android device where handling this,they restrict the music when call is in TelephonyManager.EXTRA_STATE_OFFHOOK (OFFHOOK STATE) so there is no way of playing the background music using native players and some other players like "poweramp music palyer"

2.By using the MediaPlayer class also it is not possible(clearly mentioned in documentation)

3.It is possible only in one case if your developing custom music player(with out using MediaPlayer class) in that implements

AudioManager.OnAudioFocusChangeListener by using this you can get the state of the audiomanager in the below code "focusChange=AUDIOFOCUS_LOSS_TRANSIENT"(this state calls when music is playing in background any incoming call came) this state is completely in developers hand whether to play or pause the music. As according to your requriment as for question you asked if you want to play the music when call is in OFFHOOK STATE dont pause playing music in OFFHOOK STATE .And this is only possible when headset is disabled

AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
     
    OnAudioFocusChangeListener afChangeListener = new OnAudioFocusChangeListener() {
        public void onAudioFocusChange(int focusChange) {
            if (focusChange == AUDIOFOCUS_LOSS_TRANSIENT
                // Pause playback (during incoming call) 
            } else if (focusChange == AudioManager.AUDIOFOCUS_GAIN) {
                // Resume playback (incoming call ends)
            } else if (focusChange == AudioManager.AUDIOFOCUS_LOSS) {
                am.unregisterMediaButtonEventReceiver(RemoteControlReceiver);
                am.abandonAudioFocus(afChangeListener);
                // Stop playback (when any other app playing music  in that situation current app stop the audio)
            }
        }
    };

Possible in IE and chrome although it does not work in firefox:

<script>
   function toggleZoomScreen() {
       document.body.style.zoom = "80%";
   } 
</script>

<img src="example.jpg" alt="example" onclick="toggleZoomScreen()">

You can handle the AppDomain.UnhandledException event

EDIT: actually, this event is probably more adequate: Application.DispatcherUnhandledException

You cannot set an int to null. Use a nullable int (int?) instead:

int? value = null;

Yet another variation.
Somehow, my formerly working test classes appeared to be running from some other location; my edits would not execute when I ran the tests.

I found that the output folder for my ${project_loc}src/test/java files was not what I expected. It had inadvertently been set to ${project_loc}target/classes. I set it properly in project properties, Java Build Path, Source tab.

The correct character to use in this case is a full colon (:), not a semicolon (;).

Change your gradle version in project setting: If you are using mac,click File->Project structure,then change gradle version,here:

And check your build.gradle of project,change dependency of gradle,like this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'
    }
}

you can initialize it to ' ' instead. Also, the reason that you received an error -1 being too many characters is because it is treating '-' and 1 as separate.

Try this

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1" />

if you want 0 or 1 "description" elements, Or

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="unbounded" />

if you want 0 to infinity number of "description" elements.

krtek's method has some wrong,I tested this

var startDay = 0; 
var weekStart = new Date(today.getDate() - (7 + today.getDay() - startDay) % 7);
var weekEnd = new Date(today.getDate() + (6 - today.getDay() - startDay) % 7);

it works

• com => domain
• something => company name
• something => Main package name

For example: com.paresh.mainpackage

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com. This information i have found at http://download.oracle.com/javase/tutorial/java/package/namingpkgs.html

Although it is safe to declare a static ObjectMapper in terms of thread safety, you should be aware that constructing static Object variables in Java is considered bad practice. For more details, see Why are static variables considered evil? (and if you'd like, my answer)

In short, statics should be avoided because the make it difficult to write concise unit tests. For example, with a static final ObjectMapper, you can't swap out the JSON serialization for dummy code or a no-op.

In addition, a static final prevents you from ever reconfiguring ObjectMapper at runtime. You might not envision a reason for that now, but if you lock yourself into a static final pattern, nothing short of tearing down the classloader will let you re-initialize it.

In the case of ObjectMapper its fine, but in general it is bad practice and there is no advantage over using a singleton pattern or inversion-of-control to manage your long-lived objects.

This is not something that SVG 1.1 supports. SVG 1.2 does have the textArea element, with automatic word wrapping, but it's not implemented in all browsers. SVG 2 does not plan on implementing textArea, but it does have auto-wrapped text.

However, given that you already know where your linebreaks should occur, you can break your text into multiple <tspan>s, each with x="0" and dy="1.4em" to simulate actual lines of text. For example:

<g transform="translate(123 456)"><!-- replace with your target upper left corner coordinates -->
  <text x="0" y="0">
    <tspan x="0" dy="1.2em">very long text</tspan>
    <tspan x="0" dy="1.2em">I would like to linebreak</tspan>
  </text>
</g>

Of course, since you want to do that from JavaScript, you'll have to manually create and insert each element into the DOM.

Either switch your browser in VS2017. Or open up a command prompt as administrator and do a tskill chrome about 10 times to make sure the app fully dies. Then try again. Sometimes it gets stuck on another process and even it needs to be restarted.

There doesn't seem to be a way to get the INSERT statements from the MySQL console, but you can get them using mysqldump like Rob suggested. Specify -t to omit table creation.

mysqldump -t -u MyUserName -pMyPassword MyDatabase MyTable --where="ID = 10"

In codeigniter we are able to store session values in a database. In the config.php file make the sess_use_database variable true

$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'ci_sessions';

and create a ci_session table in the database

CREATE TABLE IF NOT EXISTS  `ci_sessions` (
    session_id varchar(40) DEFAULT '0' NOT NULL,
    ip_address varchar(45) DEFAULT '0' NOT NULL,
    user_agent varchar(120) NOT NULL,
    last_activity int(10) unsigned DEFAULT 0 NOT NULL,
    user_data text NOT NULL,
    PRIMARY KEY (session_id),
    KEY `last_activity_idx` (`last_activity`)
);

to sum it up

1) in AndroidStudio's settings > compile enable checkbox named Compile independent modules in parallel.

2) Under Help> Edit Custom VM Options I have:

-Xms1024m 
-Xmx4096m # <------ increase this to most of your RAM 
-XX:MaxPermSize=1024m 
-XX:ReservedCodeCacheSize=440m 
-XX:+UseCompressedOops 
-XX:-HeapDumpOnOutOfMemoryError 
-Dfile.encoding=UTF-8

P.S. - Some people say Note, instead of VM options, it's better to combine can be overriden by combining those lines into one line single command in gradle.properties, like this :

org.gradle.jvmargs=-Xms1024m -Xmx4096m ......

3) I have an old dual core with 4GB ram, running ubuntu. Qs command line option I have only --offline (which specifies that the build should operate without accessing network resources). I also enabled the remaining checkboxes and now it's running ok:

• Make project automatically

• Use in-process building Configure on demand

• Check the AndroidStudio's settings, under compile that the checkbox Compile independent modules in parallel is enabled.

Under Vmoptions I have

-Xmx2048m -XX:MaxPermSize=1024

I have an old dual core with 4GB ram, running ubuntu. Qs commandline option I have only --offline , which specifies that the build should operate without accessing network resources. I enabled also the remaining checkboxes:

1. Make project automatically
2. Use in-process building

3. Configure on demand

   and it is running ok

Edit

It is possible to provide additional options through studio.vmoptions located at (just replace X.X with version):

• Windows: go to %USERPROFILE%\.AndroidStudioX.X\studio.exe.vmoptions (or studio64.exe.vmoptions)

• Mac: ~/Library/Preferences/.AndroidStudioX.X/studio.vmoptions

• Linux: ~/.AndroidStudioX.X/studio.vmoptions (and/or studio64.vmoptions)

Increasing the value of -Xmx should help a lot. E.g

-Xms1024m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=256m
-XX:+UseCompressedOops

will assign 4G as max heap, with initial value of 1G

Edit:

On windows the defaults are stored into C:\Program Files\Android\Android Studio\bin\*.vmoptions. The IDE allows you to tweak those values through Help->Edit Custom VM options (thanks to @Code-Read for pointing it out).

EDIT 2:

Android studio 3.5 makes easier to change same of those values. Just go to:

Preferences > Appearance & Behavior > System Settings > Memory Settings

OAuth 2.0 signatures are not required for the actual API calls once the token has been generated. It has only one security token.

OAuth 1.0 requires client to send two security tokens for each API call, and use both to generate the signature. It requires the protected resources endpoints have access to the client credentials in order to validate the request.

Here describes the difference between OAuth 1.0 and 2.0 and how both work.

I recently inherited a report that I needed to make a few changes. After following all the recommendations above, it did not help. The report historically had this extra page, and nobody could figure out why.

I right clicked on the tablix and selected properties. There was a checkbox checked that said add a page break after. After removing this, it prints on one page now.

Try and retrieve the text property of the link button in the code behind:

protected void ENameLinkBtn_Click (object sender, EventArgs e)
{
   string val = ((LinkButton)sender).Text
}

Since there's no Request context in the pipeline during app start anymore, I can't imagine there's any way to guess what server/port the next actual request might come in on. You have to so it on Begin_Session.

Here's what I'm using when not in Classic Mode. The overhead is negligible.

/// <summary>
/// Class is called only on the first request
/// </summary>
private class AppStart
{
    static bool _init = false;
    private static Object _lock = new Object();

    /// <summary>
    /// Does nothing after first request
    /// </summary>
    /// <param name="context"></param>
    public static void Start(HttpContext context)
    {
        if (_init)
        {
            return;
        }
        //create class level lock in case multiple sessions start simultaneously
        lock (_lock)
        {
            if (!_init)
            {
                string server = context.Request.ServerVariables["SERVER_NAME"];
                string port = context.Request.ServerVariables["SERVER_PORT"];
                HttpRuntime.Cache.Insert("basePath", "http://" + server + ":" + port + "/");
                _init = true;
            }
        }
    }
}

protected void Session_Start(object sender, EventArgs e)
{
    //initializes Cache on first request
    AppStart.Start(HttpContext.Current);
}

The assertion libraries in Mocha work by throwing an error if the assertion was not correct. Throwing an error results in a rejected promise, even when thrown in the executor function provided to the catch method.

.catch((error) => {
  assert.isNotOk(error,'Promise error');
  done();
});

In the above code the error objected evaluates to true so the assertion library throws an error... which is never caught. As a result of the error the done method is never called. Mocha's done callback accepts these errors, so you can simply end all promise chains in Mocha with .then(done,done). This ensures that the done method is always called and the error would be reported the same way as when Mocha catches the assertion's error in synchronous code.

it('should transition with the correct event', (done) => {
  const cFSM = new CharacterFSM({}, emitter, transitions);
  let timeout = null;
  let resolved = false;
  new Promise((resolve, reject) => {
    emitter.once('action', resolve);
    emitter.emit('done', {});
    timeout = setTimeout(() => {
      if (!resolved) {
        reject('Timedout!');
      }
      clearTimeout(timeout);
    }, 100);
  }).then(((state) => {
    resolved = true;
    assert(state.action === 'DONE', 'should change state');
  })).then(done,done);
});

I give credit to this article for the idea of using .then(done,done) when testing promises in Mocha.

Thanks to many of the answers above and elsewhere, this was my solution to a similar problem to the OP. The problem for me was creating a button in Word that asks the user for a network address, and pulls up the LAN resources in an Explorer window.

Untouched, the code would take you to \\10.1.1.1\Test, so edit as you see fit. I'm just a monkey on a keyboard, here, so all comments and suggestions are welcome.

Private Sub CommandButton1_Click()
    Dim ipAddress As Variant
    On Error GoTo ErrorHandler

    ipAddress = InputBox("Please enter the IP address of the network resource:", "Explore a network resource", "\\10.1.1.1")
    If ipAddress <> "" Then
        ThisDocument.FollowHyperlink ipAddress & "\Test"
    End If

    ExitPoint:
        Exit Sub

    ErrorHandler:
        If Err.Number = "4120" Then
            GoTo ExitPoint
        ElseIf Err.Number = "4198" Then
            MsgBox "Destination unavailable"
            GoTo ExitPoint
        End If

        MsgBox "Error " & Err.Number & vbCrLf & Err.Description
        Resume ExitPoint

Some commentors already stated that answers to your question will not work for all distributions. Since you did not include CentOS in the question but only in the tags, I'd like to post here the topics one has to understand in order to have a control over his/her proceeding regardless of the distribution:

1. what is the init daemon (optional)
2. what is the inittab file (/etc/inittab)
3. what does the inittab file do in your distro (e.g. does it actually run all scripts in /etc/init.d ?)

For your problem, one could start the script on sysinit by adding this line in /etc/inittab and make it respawn in case it terminates:

# start and respawn after termination
ttyS0::respawn:/bin/sh /path/to/my_script.sh

The script has to be made executable in advance of course:

chmod +x /path/to/my_script.sh

Hope this helps

.gitattributes - is a root-level file of your repository that defines the attributes for a subdirectory or subset of files.

You can specify the attribute to tell Git to use different merge strategies for a specific file. Here, we want to preserve the existing config.xml for our branch. We need to set the merge=foo to config.xml in .gitattributes file.

merge=foo tell git to use our(current branch) file, if a merge conflict occurs.

1. Add a .gitattributes file at the root level of the repository

2. You can set up an attribute for confix.xml in the .gitattributes file

    <pattern> merge=foo
   

   Let's take an example for config.xml

    config.xml merge=foo
   

3. And then define a dummy foo merge strategy with:

    $ git config --global merge.foo.driver true
   

If you merge the stag form dev branch, instead of having the merge conflicts with the config.xml file, the stag branch's config.xml preserves at whatever version you originally had.

for more reference: merge_strategies

Imagine you end up with double dashes, and want to replace them with a single character and not doubles of the replace character. You can just use array split and array filter and array join.

var str = "This-is---a--news-----item----";

Then to replace all dashes with single spaces, you could do this:

var newStr = str.split('-').filter(function(item) {
  item = item ? item.replace(/-/g, ''): item
  return item;
}).join(' ');

Now if the string contains double dashes, like '----' then array split will produce an element with 3 dashes in it (because it split on the first dash). So by using this line:

item = item ? item.replace(/-/g, ''): item

The filter method removes those extra dashes so the element will be ignored on the filter iteration. The above line also accounts for if item is already an empty element so it doesn't crash on item.replace.

Then when your string join runs on the filtered elements, you end up with this output:

"This is a news item"

Now if you were using something like knockout.js where you can have computer observables. You could create a computed observable to always calculate "newStr" when "str" changes so you'd always have a version of the string with no dashes even if you change the value of the original input string. Basically they are bound together. I'm sure other JS frameworks can do similar things.

1) check if service declaration in manifest is nested in application tag

<application>
    <service android:name="" />
</application>

2) check if your service.java is in the same package or diff package as the activity

<application>
    <!-- service.java exists in diff package -->
    <service android:name="com.package.helper.service" /> 
</application>

<application>
    <!-- service.java exists in same package -->
    <service android:name=".service" /> 
</application>

std::stringstream::str() is the method you are looking for.

With std::stringstream:

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::stringstream ss;
    ss << NumericValue;
    return ss.str();
}

std::stringstream is a more generic tool. You can use the more specialized class std::ostringstream for this specific job.

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::ostringstream oss;
    oss << NumericValue;
    return oss.str();
}

If you are working with std::wstring type of strings, you must prefer std::wstringstream or std::wostringstream instead.

template <class T>
std::wstring YourClass::NumericToString(const T & NumericValue)
{
    std::wostringstream woss;
    woss << NumericValue;
    return woss.str();
}

if you want the character type of your string could be run-time selectable, you should also make it a template variable.

template <class CharType, class NumType>
std::basic_string<CharType> YourClass::NumericToString(const NumType & NumericValue)
{
    std::basic_ostringstream<CharType> oss;
    oss << NumericValue;
    return oss.str();
}

For all the methods above, you must include the following two header files.

#include <string>
#include <sstream>

Note that, the argument NumericValue in the examples above can also be passed as std::string or std::wstring to be used with the std::ostringstream and std::wostringstream instances respectively. It is not necessary for the NumericValue to be a numeric value.

Just make a custom userform that is shown when the "delete" button is pressed, then link the continue button to the actual code that does the deleting. Make the cancel button hide the userform.

You want only one option by default, but the user can select multiple options by pressing the CTRL key. This is (already) exactly how the SELECT multiple is meant to behave.

Can you please clarify your question?

Sometimes you inherit brittle code that is already expecting magic values in a lot of places. Everyone is correct, you should use NULL if possible. However, as a shortcut to make sure every reference to that value is the same, I like to put "constants" (for lack of a better name) in SQL in a scaler function and then call that function when I need the value. That way if I ever want to update them all to be something else, I can do so easily. Or if I want to change the default value moving forward, I only have one place to update it.

The following code creates the function and a table using it for the default DateTime value. Then inserts and select from the table without specifying the value for Modified. Then cleans up after itself. I hope this helps.

-- CREATE FUNCTION
CREATE FUNCTION dbo.DateTime_MinValue ( )
RETURNS DATETIME
AS 
    BEGIN
        DECLARE @dateTime_min DATETIME ;
        SET @dateTime_min = '1/1/1753 12:00:00 AM'
        RETURN @dateTime_min ;
    END ;
GO


-- CREATE TABLE USING FUNCTION FOR DEFAULT
CREATE TABLE TestTable
(
  TestTableId INT IDENTITY(1, 1)
                  PRIMARY KEY CLUSTERED ,
  Value VARCHAR(50) ,
  Modified DATETIME DEFAULT dbo.DateTime_MinValue()
) ;


-- INSERT VALUE INTO TABLE
INSERT  INTO TestTable
        ( Value )
VALUES  ( 'Value' ) ;


-- SELECT FROM TABLE
SELECT  TestTableId ,
        VALUE ,
        Modified
FROM    TestTable ;


-- CLEANUP YOUR DB
DROP TABLE TestTable ;
DROP FUNCTION dbo.DateTime_MinValue ;

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

you can use native javascript like this

<script>_x000D_
function myFunction() {_x000D_
  var input, filter, table, tr, td, i;_x000D_
  input = document.getElementById("myInput");_x000D_
  filter = input.value.toUpperCase();_x000D_
  table = document.getElementById("myTable");_x000D_
  tr = table.getElementsByTagName("tr");_x000D_
  for (i = 0; i < tr.length; i++) {_x000D_
    td = tr[i].getElementsByTagName("td")[0];_x000D_
    if (td) {_x000D_
      if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {_x000D_
        tr[i].style.display = "";_x000D_
      } else {_x000D_
        tr[i].style.display = "none";_x000D_
      }_x000D_
    }       _x000D_
  }_x000D_
}_x000D_
</script>

Swift 4

To get the first N elements of a Swift array you can use prefix(_ maxLength: Int):

Array(largeArray.prefix(5))

I hope following example shed some light on constructor chaining.
my use case here for example, you are expecting user to pass a directory to your constructor, user doesn't know what directory to pass and decides to let you assign default directory. you step up and assign a default directory that you think will work.

BTW, I used LINQPad for this example in case you are wondering what *.Dump() is.
cheers

void Main()
{

    CtorChaining ctorNoparam = new CtorChaining();
    ctorNoparam.Dump();
    //Result --> BaseDir C:\Program Files (x86)\Default\ 

    CtorChaining ctorOneparam = new CtorChaining("c:\\customDir");
    ctorOneparam.Dump();    
    //Result --> BaseDir c:\customDir 
}

public class CtorChaining
{
    public string BaseDir;
    public static string DefaultDir = @"C:\Program Files (x86)\Default\";


    public CtorChaining(): this(null) {}

    public CtorChaining(string baseDir): this(baseDir, DefaultDir){}

    public CtorChaining(string baseDir, string defaultDir)
    {
        //if baseDir == null, this.BaseDir = @"C:\Program Files (x86)\Default\"
        this.BaseDir = baseDir ?? defaultDir;
    }
}

Anyway, I was following my workflow on a recent branch, and when I tried to merge it back to master, it all went to hell. There were tons of conflicts with things that should have not mattered. The conflicts just made no sense to me. It took me a day to sort everything out, and eventually culminated in a forced push to the remote master, since my local master has all conflicts resolved, but the remote one still wasn't happy.

In neither your partner's nor your suggested workflows should you have come across conflicts that didn't make sense. Even if you had, if you are following the suggested workflows then after resolution a 'forced' push should not be required. It suggests that you haven't actually merged the branch to which you were pushing, but have had to push a branch that wasn't a descendent of the remote tip.

I think you need to look carefully at what happened. Could someone else have (deliberately or not) rewound the remote master branch between your creation of the local branch and the point at which you attempted to merge it back into the local branch?

Compared to many other version control systems I've found that using Git involves less fighting the tool and allows you to get to work on the problems that are fundamental to your source streams. Git doesn't perform magic, so conflicting changes cause conflicts, but it should make it easy to do the write thing by its tracking of commit parentage.

Old thread, but I haven't found my way of doing it. It might be valuable for someone who works with rebase and wants to merge all the commits from a (feature) branch on top of master. If there is a conflict on the way, you can resolve them for every commit. You keep full control during the process and can abort any time.

Get Master and Branch up-to-date:

git checkout master
git pull --rebase origin master
git checkout <branch_name>
git pull --rebase origin <branch_name>

Merge Branch on top of Master:

git checkout <branch_name>
git rebase master

Optional: If you run into Conflicts during the Rebase:

First, resolve conflict in file. Then:

git add .
git rebase --continue

Push your rebased Branch:

git push origin <branch_name>

Now you've got two options:

• A) Create a PR (e.g. on GitHub) and merge it there via the UI
• B) Go back on the command line and merge the branch into master

git checkout master
git merge --no-ff <branch_name>
git push origin master

Done.

Another approach is to use timestamp values:

end_time.timestamp() - start_time.timestamp()

include the css file into your blade template in laravel

1. move css file into public->css folder in your laravel project.
2. use <link rel="stylesheet" href="{{ asset('css/filename') }}">

so css is applied in a blade.php file.

You can generate easily with livegap charts
Select Mulicolors from Bar menu

_{(source: livegap.com)}

** chart library used is chartnew.js modified version of chart.js library
with chartnew.js code will be something like this

var barChartData = {
        labels: ["001", "002", "003", "004", "005", "006", "007"],
        datasets: [
            {
                label: "My First dataset",
                fillColor: ["rgba(0,10,220,0.5)","rgba(220,0,10,0.5)","rgba(220,0,0,0.5)","rgba(120,250,120,0.5)" ],
                strokeColor: "rgba(220,220,220,0.8)", 
                highlightFill: "rgba(220,220,220,0.75)",
                highlightStroke: "rgba(220,220,220,1)",
                data: [20, 59, 80, 81, 56, 55, 40]
            }
        ]
    };

It depends what you wanted to do with that column e.g. here's an example of appending a new column to a recordset which can be updated on the client side:

Sub MSDataShape_AddNewCol()

  Dim rs As ADODB.Recordset
  Set rs = CreateObject("ADODB.Recordset")
  With rs
    .ActiveConnection = _
    "Provider=MSDataShape;" & _
    "Data Provider=Microsoft.Jet.OLEDB.4.0;" & _
    "Data Source=C:\Tempo\New_Jet_DB.mdb"
    .Source = _
    "SHAPE {" & _
    " SELECT ExistingField" & _
    " FROM ExistingTable" & _
    " ORDER BY ExistingField" & _
    "} APPEND NEW adNumeric(5, 4) AS NewField"

    .LockType = adLockBatchOptimistic

    .Open

    Dim i As Long
    For i = 0 To .RecordCount - 1
      .Fields("NewField").Value = Round(.Fields("ExistingField").Value, 4)
      .MoveNext
    Next

    rs.Save "C:\rs.xml", adPersistXML

  End With
End Sub

It is better to avoid writing out temporary spool files. Use a PL/SQL block. You can run this from SQL*Plus or put this thing into a package or procedure. The join to USER_TABLES is there to avoid view constraints.

It's unlikely that you really want to disable all constraints (including NOT NULL, primary keys, etc). You should think about putting constraint_type in the WHERE clause.

BEGIN
  FOR c IN
  (SELECT c.owner, c.table_name, c.constraint_name
   FROM user_constraints c, user_tables t
   WHERE c.table_name = t.table_name
   AND c.status = 'ENABLED'
   AND NOT (t.iot_type IS NOT NULL AND c.constraint_type = 'P')
   ORDER BY c.constraint_type DESC)
  LOOP
    dbms_utility.exec_ddl_statement('alter table "' || c.owner || '"."' || c.table_name || '" disable constraint ' || c.constraint_name);
  END LOOP;
END;
/

Enabling the constraints again is a bit tricker - you need to enable primary key constraints before you can reference them in a foreign key constraint. This can be done using an ORDER BY on constraint_type. 'P' = primary key, 'R' = foreign key.

BEGIN
  FOR c IN
  (SELECT c.owner, c.table_name, c.constraint_name
   FROM user_constraints c, user_tables t
   WHERE c.table_name = t.table_name
   AND c.status = 'DISABLED'
   ORDER BY c.constraint_type)
  LOOP
    dbms_utility.exec_ddl_statement('alter table "' || c.owner || '"."' || c.table_name || '" enable constraint ' || c.constraint_name);
  END LOOP;
END;
/

Some additional info. for situations that'll need the win32gui solution posted by Mohsen Haddadi earlier in this thread:

As of python 361, win32gui & win32con are not part of the python std library. To use them, pywin32 package will need to be installed; now possible via pip.

More background info on pywin32 package is at: How to use the win32gui module with Python?.

Also, to apply discretion while closing a window so as to not inadvertently close any window in the foreground, the resolution could be extended along the lines of the following:

try     :

    import win32gui, win32con;

    frgrnd_wndw = win32gui.GetForegroundWindow();
    wndw_title  = win32gui.GetWindowText(frgrnd_wndw);
    if wndw_title.endswith("python.exe"):
        win32gui.ShowWindow(frgrnd_wndw, win32con.SW_HIDE);
    #endif
except  :
    pass

You can use an async result and a delegate for this. If you read up on the documentation it should make it pretty clear what to do. I can write up some sample code if you like and attach it to this answer.

Action isExcelInteractive = IsExcelInteractive;

private async void btnOk_Click(object sender, EventArgs e)
{
    IAsyncResult result = isExcelInteractive.BeginInvoke(ItIsDone, null);
    result.AsyncWaitHandle.WaitOne();
    Console.WriteLine("YAY");
} 

static void IsExcelInteractive(){
   while (something_is_false) // do your check here
   {
       if(something_is_true)
          return true;
   }
   Thread.Sleep(1);
}

void ItIsDone(IAsyncResult result)
{
   this.isExcelInteractive.EndInvoke(result);
}

Apologies if this code isn't 100% complete, I don't have Visual Studio on this computer, but hopefully it gets you where you need to get to.

You can use E6 destructuring:

Object destructuring:

promise = new Promise(function(onFulfilled, onRejected){
    onFulfilled({arg1: value1, arg2: value2});
})

promise.then(({arg1, arg2}) => {
    // ....
});

Array destructuring:

promise = new Promise(function(onFulfilled, onRejected){
    onFulfilled([value1, value2]);
})

promise.then(([arg1, arg2]) => {
    // ....
});

Because break cannot be used to break out of an if - it can only break out of loops. That's the way Python (and most other languages) are specified to behave.

What are you trying to do? Perhaps you should use sys.exit() or return instead?

Use like this!

interface Iinput {
  label: string
  placeholder: string
  register: any
  type?: string
  required: boolean
}


// This is how it can be done

const inputs: Array<Iinput> = [
  {
    label: "Title",
    placeholder: "Bought something",
    register: register,
    required: true,
  },
]

You could look into psh here: http://gnp.github.io/psh/

It's a full on shell (you can use it in replacement of bash for example), but uses perl syntax.. so you can create methods on the fly etc.

I recently solved this problem with a good solution.

CSS:

.avoidBreak { 
    border: 2px solid;
    page-break-inside:avoid;
}

JS:

function Print(){
    $(".tableToPrint td, .tableToPrint th").each(function(){ $(this).css("width",  $(this).width() + "px")  });
    $(".tableToPrint tr").wrap("<div class='avoidBreak'></div>");
    window.print();
}

Works like a charm!

Here's another simple solution. The following code will return everything before the '|' character:

if (path.Contains('|'))
   path = path.Split('|')[0];

In fact, you could have as many separators as you want, but assuming you only have one separation character, here is how you would get everything after the '|':

if (path.Contains('|'))
   path = path.Split('|')[1];

(All I changed in the second piece of code was the index of the array.)

Coping with different aspect ratios

The different aspect ratios seen above are (from most square; h/w):

1:1     1.0     <- rare for phone; common for watch
4:3     1.3333  <- matches iPad (when portrait)
3:2     1.5000
38:25   1.5200
14:9    1.5556  <- rare
25:16   1.5625
8:5     1.6000  <- aka 16:10
5:3     1.6667
128:75  1.7067
16:9    1.7778  <- matches iPhone 5-7
427:240 1.7792  <- rare
37:18   2.0555  <- Galaxy S8

If you skip the extreme aspect ratios, that are rarely seen at phone size or larger, all the other devices fit a range from 1.3333 to 1.7778, which conveniently matches the current iPhone/iPad ratios (considering all devices in portrait mode). Note that there are quite a few variations within that range, so if you are creating a small number of fixed aspect-ratio layouts, you will need to decide how to handle the odd "in-between" screens.

Minimum "portrait mode" solution is to support 1.3333, which results in unused space at top and bottom, on all the resolutions with larger aspect ratio.
Most likely, you would instead design it to stretch over the 1.333 to 1.778 range. But sometimes part of your design looks too distorted then.

Advanced layout ideas:

For text, you can design for 1.3333, then increase line spacing for 1.666 - though that will look quite sparse. For graphics, design for an intermediate ratio, so that on some screens it is slightly squashed, on others it is slightly stretched. geometric mean of Sqrt(1333 x 1667) ~= 1491. So you design for 1491 x 1000, which will be stretched/squashed by +-12% when assigned to the extreme cases.

Next refinement is to design layout as a stack of different-height "bands" that each fill the width of the screen. Then determine where you can most pleasingly "stretch-or-squash" a band's height, to adjust for different ratios.

For example, consider imaginary phones with 1333 x 1000 pixels and 1666 x 1000 pixels. Suppose you have two "bands", and your main "band" is square, so it is 1000 x 1000. Second band is 333 x 1000 on one screen, 666 x 1000 on the other - quite a range to design for.
You might decide your main band looks okay altered 10% up-or-down, and squash it 900 x 1000 on the 1333 x 1000 screen, leaving 433 x 1000. Then stretch it to 1100 x 1000 on 1666 x 1000 screen, leaving 566 x 1000. So your second band now needs to adjust over only 433 to 566, which has geometric mean of Sqrt(433 x 566) ~= 495. So you design for 495 x 1000, which will be stretched/squashed by +-14% when assigned to the extreme cases.

You should iterate over the keys and get the values using square brackets.

EDIT: Obviously, this makes the question a duplicate.

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

You can think of an iframe as an embedded browser window that you can put on an HTML page to show another URL inside it. This URL can be totally distinct from your web site/app.

You can put an iframe in any HTML page, so you could put one inside a contentplaceholder in a webform that has a Masterpage and it will appear with whatever URL you load into it (via Javascript, or C# if you turn your iframe into a server-side control (runat='server') on the final HTML page that your webform produces when requested.

And you can load a URL into your iframe that is a .aspx page.

But - iframes have nothing to do with the ASP.net mechanism. They are HTML elements that can be made to run server-side, but they are essentially 'dumb' and unmanaged/unconnected to the ASP.Net mechanisms - don't confuse a Contentplaceholder with an iframe.

Incidentally, the use of iframes is still contentious - do you really need to use one? Can you afford the negative trade-offs associated with them e.g. lack of navigation history ...?

Using the provided IntentInegrator is better. It allows you to prompt your user to install the barcode scanner if they do not have it. It also allows you to customize the messages. The IntentIntegrator.REQUEST_CODE constant holds the value of the request code for the onActivityResult to check for in the above if block.

IntentIntegrator intentIntegrator = new IntentIntegrator(this); // where this is activity 
intentIntegrator.initiateScan(IntentIntegrator.ALL_CODE_TYPES); // or QR_CODE_TYPES if you need to scan QR

Just add style="table-layout: fixed ; width: 100%;" inside <table> tag and also if you do not specify any styles and add just style=" width: 100%;" inside <table> You will be able to resolve it.

Others have noted that you can use the built-in File.ReadAllBytes. The built-in method is fine, but it's worth noting that the code you post above is fragile for two reasons:

1. Stream is IDisposable - you should place the FileStream fs = new FileStream(filename, FileMode.Open,FileAccess.Read) initialization in a using clause to ensure the file is closed. Failure to do this may mean that the stream remains open if a failure occurs, which will mean the file remains locked - and that can cause other problems later on.
2. fs.Read may read fewer bytes than you request. In general, the .Read method of a Stream instance will read at least one byte, but not necessarily all bytes you ask for. You'll need to write a loop that retries reading until all bytes are read. This page explains this in more detail.

Here's a flowchart based on "When to use each method of launching a subprocess in Ruby". See also, "Trick an application into thinking its stdout is a terminal, not a pipe".

RFC 7396: JSON Merge Patch (published four years after the question was posted) describes the best practices for a PATCH in terms of the format and processing rules.

In a nutshell, you submit an HTTP PATCH to a target resource with the application/merge-patch+json MIME media type and a body representing only the parts that you want to be changed/added/removed and then follow the below processing rules.

Rules:

• If the provided merge patch contains members that do not appear within the target, those members are added.

• If the target does contain the member, the value is replaced.

• Null values in the merge patch are given special meaning to indicate the removal of existing values in the target.

Example test cases that illustrate the rules above (as seen in the appendix of that RFC):

In python 3, reload is no longer a built in function.

If you are using python 3.4+ you should use reload from the importlib library instead:

import importlib
importlib.reload(some_module)

If you are using python 3.2 or 3.3 you should:

import imp  
imp.reload(module)  

instead. See http://docs.python.org/3.0/library/imp.html#imp.reload

If you are using ipython, definitely consider using the autoreload extension:

%load_ext autoreload
%autoreload 2

vim may be challenging for beginners. For a quick-and-dirty Windows console-mode text editor, I would suggest Kinesics Text Editor.

 string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
 string extension = ".log";
 filePath += @"\Error Log\" + extension;
 if (!Directory.Exists(filePath))
 {
      Directory.CreateDirectory(filePath);
 }

A struct is a value type. If you assign a struct to a new variable, the new variable will contain a copy of the original.

public struct IntStruct {
    public int Value {get; set;}
}

Excecution of the following results in 5 instances of the struct stored in memory:

var struct1 = new IntStruct() { Value = 0 }; // original
var struct2 = struct1;  // A copy is made
var struct3 = struct2;  // A copy is made
var struct4 = struct3;  // A copy is made
var struct5 = struct4;  // A copy is made

// NOTE: A "copy" will occur when you pass a struct into a method parameter.
// To avoid the "copy", use the ref keyword.

// Although structs are designed to use less system resources
// than classes.  If used incorrectly, they could use significantly more.

A class is a reference type. When you assign a class to a new variable, the variable contains a reference to the original class object.

public class IntClass {
    public int Value {get; set;}
}

Excecution of the following results in only one instance of the class object in memory.

var class1 = new IntClass() { Value = 0 };
var class2 = class1;  // A reference is made to class1
var class3 = class2;  // A reference is made to class1
var class4 = class3;  // A reference is made to class1
var class5 = class4;  // A reference is made to class1  

Structs may increase the likelihood of a code mistake. If a value object is treated like a mutable reference object, a developer may be surprised when changes made are unexpectedly lost.

var struct1 = new IntStruct() { Value = 0 };
var struct2 = struct1;
struct2.Value = 1;
// At this point, a developer may be surprised when 
// struct1.Value is 0 and not 1

As of today with flexbox, you could

PREVIOUS ANSWER

html, body {height:100%;}
html {display:table; width:100%;}
body {display:table-cell; text-align:center; vertical-align:middle;}

I know this is very old post. I thought to share my knowledge here !

For the date Mid night today with exact Time zone you can use following

public static Date getCurrentDateWithMidnightTS(){

    return new Date(System.currentTimeMillis() - (System.currentTimeMillis()%(1000*60*60*24)) - (1000*60 * 330));
}

Where (1000*60 * 330) is being subtracted i.e. actually related to time zone for example Indian time zone i.e. kolkata differs +5:30hrs from actual . So subtracting that with converting into milliseconds.

So change last substracted number according to you. I m creating a product i.e. only based in India So just used specific timestamp.

I'd like to plug in some (shallow) reasons I have experienced as follows:

1. we may have updated our dictionary(for NLP tasks) but the model and the prepared data used a different one.
2. we may have reprocessed our data(binary tf_record) but we loaded the old model. The reprocessed data may conflict with the previous one.
3. we may should train the model from scratch but we forgot to delete the checkpoints and the model loaded the latest parameters automatically.

Hope that helps.

What about

$.ajax({
  type: 'POST',
  url: $("form").attr("action"),
  data: $("form").serialize(), 
  //or your custom data either as object {foo: "bar", ...} or foo=bar&...
  success: function(response) { ... },
});

Another way based on a merge of serveral responses here before :

docker-compose file :

version: "3"
services:
    db:
      container_name: db
      image: mysql
      ports:
       - "3306:3306"  
      environment:
         - MYSQL_ROOT_PASSWORD=mysql
         - MYSQL_DATABASE=db

      volumes:
         - /home/user/db/mysql/data:/var/lib/mysql
         - /home/user/db/mysql/init:/docker-entrypoint-initdb.d/:ro

where /home/user.. is a shared folder on the host

And in the /home/user/db/mysql/init folder .. just drop one sql file, with any name, for example init.sql containing :

CREATE DATABASE mydb;
GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'%' IDENTIFIED BY 'mysql';
GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'localhost' IDENTIFIED BY 'mysql';
USE mydb
CREATE TABLE CONTACTS (
    [ ... ]
);
INSERT INTO CONTACTS VALUES ...
[ ... ]

According to the official mysql documentation, you can put more than one sql file in the docker-entrypoint-initdb.d, they are executed in the alphabetical order

The correct way to do this is as follows:

1. Run the command:

   sp_help [table name] 
   

2. Copy the name of the CONSTRAINT.

3. Drop the DEFAULT CONSTRAINT:

   ALTER TABLE [table name] DROP [NAME OF CONSTRAINT] 
   

4. Run the command below:

   ALTER TABLE [table name] ADD DEFAULT [DEFAULT VALUE] FOR [NAME OF COLUMN]
   

One way:

wc -l < log.txt | xargs echo -n

IF the table is alias t

SELECT t.Present , t.previous, t.previous- t.Present AS Difference
FROM   temp1 as t

I have 2 alarms. I am using intent with extras instead of action to identify the events:

Intent i = new Intent(context, AppReciever.class);
i.putExtra("timer", "timer1");

the thing is that with diff extras the intent (and the alarm) wont be unique. So to able to identify which alarm is active or not, I had to define diff requestCode-s:

boolean alarmUp = (PendingIntent.getBroadcast(context, MyApp.TIMER_1, i, 
                    PendingIntent.FLAG_NO_CREATE) != null);

and here is how alarm was created:

public static final int TIMER_1 = 1;
public static final int TIMER_2 = 2;

PendingIntent pending = PendingIntent.getBroadcast(context, TIMER_1, i,
            PendingIntent.FLAG_CANCEL_CURRENT);
setInexactRepeating(AlarmManager.RTC_WAKEUP,
            cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pending);
pending = PendingIntent.getBroadcast(context, TIMER_2, i,
            PendingIntent.FLAG_CANCEL_CURRENT);
setInexactRepeating(AlarmManager.RTC_WAKEUP,
            cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pending);

Expanding a little bit on the previous answer, you can make the footnote links clickable here as well. First define the footnote at the bottom like this

<a name="myfootnote1">1</a>: Footnote content goes here

Then reference it at some other place in the document like this

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

I was working on a nice defect last time and was wondering more about how to use properly hover property for A tag link and for IE browser. A strange thing for me was that IE was not able to capture A tag link element based on a simple A selector. So, I found out how to even force capturing A tag element and I spotted that we must use more specifc CSS selector. Here is an example below - It works perfect:

li a[href]:hover {...}

USe this function for date comparison in javascript:

    function fn_DateCompare(DateA, DateB) {
      var a = new Date(DateA);
      var b = new Date(DateB);

      var msDateA = Date.UTC(a.getFullYear(), a.getMonth()+1, a.getDate());
      var msDateB = Date.UTC(b.getFullYear(), b.getMonth()+1, b.getDate());

      if (parseFloat(msDateA) < parseFloat(msDateB))
        return -1;  // less than
      else if (parseFloat(msDateA) == parseFloat(msDateB))
        return 0;  // equal
      else if (parseFloat(msDateA) > parseFloat(msDateB))
        return 1;  // greater than
      else
        return null;  // error
  }

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

Follow these basic steps to fix this problem,

Step 1: Go to Dashboard,

Step 2: Go to "App Review" tab,

Step 3: Enable the "Make test public?" option, Like Below image,

There is no notion of method overloading in Python. But you can achieve a similar effect by specifying optional and keyword arguments

Personally none of the above worked for me. What did:

new_str = [str(x) for x in old_obj][0]

Dude, this is a freaking brilliant idea! Why didn't I find out about this back in 1998? Anyway, here's my interpretation of the Fran tutorial. Suggestions are most welcome, I am thinking about starting a game engine based on this.

In short: If every component can be treated like a number, the whole system can be treated like a math equation, right?

I like to avoid jquery (and other 90-140k libs), and as noted browsers handle onclick first, so here is what I did on a website I created (this example also covers getting a clicked location local x y )

clicksNow-0; //global js, owell

function notify2(e, right) {  // called from onclick= and oncontextmenu= (rc)
var x,y,xx,yy;
var ele = document.getElementById('wrap');  
    // offset fixed parent for local win x y
var xxx= ele.offsetLeft;
var yyy= ele.offsetTop;

//NScape
if (document.layers || document.getElementById&&!document.all) {
    xx= e.pageX;
    yy= e.pageY;
} else {
    xx= e.clientX;
    yy= e.clientY;
}
x=xx-xxx;
y=yy-yyy;

clicksNow++;
    // 200 (2/10ths a sec) is about a low as i seem to be able to go
setTimeout( "processClick( " + right + " , " + x + " , " + y + ")", 200);
}

function processClick(right, x, y) {
if (clicksNow==0) return; // already processed as dblclick
if (clicksNow==2) alert('dbl');
clicksNow=0;
    ... handle, etc ...
}

hope that helps

Make sure you don't put a space between the semi-colon and the new folder location that you are adding to the path.

For example it should look like...

{last path entry};C:\Python27;C:\Python27\Scripts;

...not...

{last path entry}; C:\Python27; C:\Python27\Scripts;

Are you looking for the PropertyOverrideConfigurer documented here

http://static.springsource.org/spring/docs/2.5.x/reference/beans.html#beans-factory-overrideconfigurer

The PropertyOverrideConfigurer, another bean factory post-processor, is similar to the PropertyPlaceholderConfigurer, but in contrast to the latter, the original definitions can have default values or no values at all for bean properties. If an overriding Properties file does not have an entry for a certain bean property, the default context definition is used.

How about this: Collections.list(Enumeration e) returns an ArrayList<T>

Environment

My OS is Ubuntu 16.04 and jupyter is 4.3.0.

Method

First, i logged out jupyter at its homepage on browser(the logout button is at top-right)

Second, type in Ctrl + C in your terminal and it shows:

[I 15:59:48.407 NotebookApp]interrupted Serving notebooks from local directory: /home/Username 0 active kernels

The Jupyter Notebook is running at: http://localhost:8888/?token=a572c743dfb73eee28538f9a181bf4d9ad412b19fbb96c82

Shutdown this notebook server (y/[n])?

Last step, type in y within 5 sec, and if it shows:

[C 15:59:50.407 NotebookApp] Shutdown confirmed
[I 15:59:50.408 NotebookApp] Shutting down kernels

Congrats! You close your jupyter successfully.

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

I know this question has already been answered, but another option is simply to open the destination and source folders in Finder and then drag and drop them into the terminal. The paths will automatically be copied and properly formatted (thus negating the need to actually figure out proper file names/extensions).

I have to do over-network copies between Mac and Windows machines, sometimes fairly deep down in filetrees, and have found this the most effective way to do so.

So, as an example:

cp -r [drag and drop source folder from finder] [drag and drop destination folder from finder]

inside the Form, You can use this code. Replace your variable name (i use $variable)

<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">

It is not possible prolly cuz it would be so easy to XSS. Also , current HTML sanitizers that are available don't disallow content property.

(Definitely not the greatest answer here but I just wanted to share an insight other than the "according to spec... ")

To improve the blurriness, esp. on Chrome, try doing this:

transform: perspective(1px) translateZ(0);
backface-visibility: hidden;

UPDATE: Perspective adds distance between the user and the z-plane, which technically scales the object, making the blurriness seem 'permanent'. The perspective(1px) above is like duck-tape because we're matching the blurriness we're trying to solve. You might have better luck with the css below:

transform: translateZ(0);
backface-visibility: hidden;

Just wanted to add that if you want to debug stuff, you should compile with debug information before you debug, otherwise the debugger won't work. So, in g++ you need to do g++ -g source.cpp. The -g flag means that the compiler will insert debugging information into your executable, so that you can run gdb on it.

Might help some else - I came here because I missed putting two // after http:. This is what I had:

http:/abc.my.domain.com:55555/update

The accurate way is to use the __FUNCTION__ predefined magic constant.

Example:

class Test {
    function MethodA(){
        echo __FUNCTION__;
    }
}

Result: MethodA.

$sUrl = 'http://www.linktopage.com/login/';
$params = array('http' => array(
    'method'  => 'POST',
    'content' => 'username=admin195&password=d123456789'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if(!$fp) {
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if($response === false) {
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

Never mind, I found the answer.

This will do the trick.

With that solution the only scrollbar in the page is on your contents section in the middle! In that section build your structure with a sidebar or whatever you want!

You can do that with that code here:

<div class="navTop">
<h1>Title</h1>
    <nav>Dynamic menu</nav>
</div>
<div class="container">
    <section>THE CONTENTS GOES HERE</section>
</div>
<footer class="bottomFooter">
    Footer
</footer>

With that css:

.navTop{
width:100%;
border:1px solid black;
float:left;
}
.container{
width:100%;
float:left;
overflow:scroll;
}
.bottomFooter{
float:left;
border:1px solid black;
width:100%;
}

And a bit of jquery:

$(document).ready(function() {
  function setHeight() {
    var top = $('.navTop').outerHeight();
    var bottom = $('footer').outerHeight();
    var totHeight = $(window).height();
    $('section').css({ 
      'height': totHeight - top - bottom + 'px'
    });
  }

  $(window).on('resize', function() { setHeight(); });
  setHeight();
});

when new props or states being received (like you call setState here), React will invoked some functions, which are called componentWillUpdate and componentDidUpdate

in your case, just simply add a componentDidUpdate function to call this.drawGrid()

here is working code in JS Bin

as I mentioned, in the code, componentDidUpdate will be invoked after this.setState(...)

then componentDidUpdate inside is going to call this.drawGrid()

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

Beyond the problematic use of async as pointed out by @Servy, the other issue is that you need to explicitly get T from Task<T> by calling Task.Result. Note that the Result property will block async code, and should be used carefully.

Try:

private async void button1_Click(object sender, EventArgs e)
{
    var s = await methodAsync();
    MessageBox.Show(s.Result);
}

Intent intent=new Intent(String) is defined for parameter task, whereas you are passing parameter componentname into this, use instead:

Intent i = new Intent(Settings.this, com.scytec.datamobile.vd.gui.android.AppPreferenceActivity.class);
                    startActivity(i);

In this statement replace ActivityName by Name of Class of Activity, this code resides in.

As ghills had already mentioned

inp = int(input("Enter a number:"))

n = 0
for i in str(inp):
    n = n + int(i);
    print n

When you are looping through something, keyword is "IN", just always think of it as a list of something. You cannot loop through a plain integer. Therefore, it is not iterable.

SELECT DISTINCT C.valueC 
FROM C 
  LEFT JOIN B ON C.id = B.lookupC
  LEFT JOIN A ON B.id = A.lookupB
WHERE C.id IS NOT NULL

I don't see a good reason why you want to limit the result sets of A and B because what you want to have is a list of all C's that are referenced by A. I did a distinct on C.valueC because i guessed you wanted a unique list of C's.

EDIT: I agree with your argument. Even if your solution looks a bit nested it seems to be the best and fastest way to use your knowledge of the data and reduce the result sets.

There is no distinct join construct you could use so just stay with what you already have :)

Just as Commonsware mentioned, you shouldn't assume, that the stream you get via ContentResolver is convertable into file.

What you really should do is to open the InputStream from the ContentProvider, then create a Bitmap out of it. And it works on 4.4 and earlier versions as well, no need for reflection.

    //cxt -> current context

    InputStream input;
    Bitmap bmp;
    try {
        input = cxt.getContentResolver().openInputStream(fileUri);
        bmp = BitmapFactory.decodeStream(input);
    } catch (FileNotFoundException e1) {

    }

Of course if you handle big images, you should load them with appropriate inSampleSize: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html. But that's another topic.

I had a similar situation: multiple developers using the same private key, but I couldn't find mine anymore after upgrade to Lion. The very simple fix was to export the private key for the specific certificate (in my case the Development cert) from the other machine, move it to my computer and drag it into keychain access there. Xcode immediately picked it up and I was good to go.

I use CTRL-SHIFT-DELETE which activates the privacy feature, allowing you to clear your cache, reset cookies, etc, all at once. You can even configure it so that it just DOES it, instead of popping up a dialog box asking you to confirm.

font-size:0;

I was also using overflow and white-space: nowrap; float: left; seems to mess things up

Change your subplot settings to:

plt.subplot(1, 2, 1)

...

plt.subplot(1, 2, 2)

The parameters for subplot are: number of rows, number of columns, and which subplot you're currently on. So 1, 2, 1 means "a 1-row, 2-column figure: go to the first subplot." Then 1, 2, 2 means "a 1-row, 2-column figure: go to the second subplot."

You currently are asking for a 2-row, 1-column (that is, one atop the other) layout. You need to ask for a 1-row, 2-column layout instead. When you do, the result will be:

In order to minimize the overlap of subplots, you might want to kick in a:

PSR-5: PHPDoc proposes a form of Generics-style notation.

Syntax

Type[]
Type<Type>
Type<Type[, Type]...>
Type<Type[|Type]...>

Values in a Collection MAY even be another array and even another Collection.

Type<Type<Type>>
Type<Type<Type[, Type]...>>
Type<Type<Type[|Type]...>>

Examples

<?php

$x = [new Name()];
/* @var $x Name[] */

$y = new Collection([new Name()]);
/* @var $y Collection<Name> */

$a = new Collection(); 
$a[] = new Model_User(); 
$a->resetChanges(); 
$a[0]->name = "George"; 
$a->echoChanges();
/* @var $a Collection<Model_User> */

Note: If you are expecting an IDE to do code assist then it's another question about if the IDE supports PHPDoc Generic-style collections notation.

From my answer to this question.

The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

var answer = Math.floor(x)

I sincerely hope this will help future searchers when googling for this common question.

I would just like to add that if the String is originally encoded using the wrong encoding it might be impossible to change it to another encoding without errors. The question does not state that the conversion here is made from wrong encoding to correct encoding but I personally stumbled to this question just because of this situation so just a heads up for others as well.

This answer in other question gives an explanation why the conversion does not always yield correct results https://stackoverflow.com/a/2623793/4702806

int is a primitive type that represent an integer. whereas Integer is an Object that wraps int. The Integer object gives you more functionality, such as converting to hex, string, etc.

You can also use OOP concepts with Integer. For example, you can use Integer for generics (i.e. Collection<Integer>).

It is possible to write to an excel file without opening it using the Microsoft.Jet.OLEDB.4.0 and OleDb. Using OleDb, it behaves as if you were writing to a table using sql.

Here is the code I used to create and write to an new excel file. No extra references are needed

var connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\SomePath\ExcelWorkBook.xls;Extended Properties=Excel 8.0";
using (var excelConnection = new OleDbConnection(connectionString))
{
    // The excel file does not need to exist, opening the connection will create the
    // excel file for you
    if (excelConnection.State != ConnectionState.Open) { excelConnection.Open(); }

    // data is an object so it works with DBNull.Value
    object propertyOneValue = "cool!";
    object propertyTwoValue = "testing";

    var sqlText = "CREATE TABLE YourTableNameHere ([PropertyOne] VARCHAR(100), [PropertyTwo] INT)";

    // Executing this command will create the worksheet inside of the workbook

    using (var command = new OleDbCommand(sqlText, excelConnection)) { command.ExecuteNonQuery(); }

    // Add (insert) data to the worksheet

    using (var command = new OleDbCommand(commandText, excelConnection))
    {
        // We need to allow for nulls just like we would with
        // sql, if your data is null a DBNull.Value should be used
        // instead of null 
        command.Parameters.AddWithValue("@PropertyOne", propertyOneValue ?? DBNull.Value);
        command.Parameters.AddWithValue("@PropertyTwo", propertyTwoValue ?? DBNull.Value);

        command.ExecuteNonQuery();
    }
}

If you are building an uberjar or "shaded jar", make sure your meta inf service files are merged. (This bit me multiple times on a dropwizard project.)

If you are using the gradle shadowJar plugin, you want to call mergeServiceFiles() in your shadowJar target: https://github.com/johnrengelman/shadow#merging-service-files

Not sure what the analogous commands are for maven or other build systems.

This worked for me. Each month on X axis

str_month_list = ['January','February','March','April','May','June','July','August','September','October','November','December']
ax.set_xticks(range(0,12))
ax.set_xticklabels(str_month_list)

So, you need to DELETE related rows from conflicted tables or more logical to UPDATE their FOREIGN KEY column to reference other PRIMARY KEY's from the parent table.

select sequence_owner, sequence_name from dba_sequences;


DBA_SEQUENCES -- all sequences that exist 
ALL_SEQUENCES  -- all sequences that you have permission to see 
USER_SEQUENCES  -- all sequences that you own

Note that since you are, by definition, the owner of all the sequences returned from USER_SEQUENCES, there is no SEQUENCE_OWNER column in USER_SEQUENCES.

Simple like that.

include the following line in the function to close pop.

parseInt((new Date('2012.08.10').getTime() / 1000).toFixed(0))

It's important to add the toFixed(0) to remove any decimals when dividing by 1000 to convert from milliseconds to seconds.

The .getTime() function returns the timestamp in milliseconds, but true unix timestamps are always in seconds.

Change

dateTime.setText(app.getTotalDl());

To

dateTime.setText(String.valueOf(app.getTotalDl()));

There are different versions of setText - one takes a String and one takes an int resource id. If you pass it an integer it will try to look for the corresponding string resource id - which it can't find, which is your error.

I guess app.getTotalDl() returns an int. You need to specifically tell setText to set it to the String value of this int.

setText (int resid) vs setText (CharSequence text)

In the context of Drupal, the difference will depend whether clean URLs are on or not.

With them off, $_SERVER['REQUEST_URI'] will have the full path of the page as called w/ /index.php, while $_GET["q"] will just have what is assigned to q.

With them on, they will be nearly identical w/o other arguments, but $_GET["q"] will be missing the leading /. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.

TextMate with the Django and django-html bundles installed gives you syntax highlighting and great extensibility. It is lightweight and fun to use.

Here is a link to a code completion project for TextMate with Python (which I haven't used myself). As for "intellisense" (which I understand to be inline-doc reference), TextMate has that too.

Try run HTTP over UDP with node-httpp:

You should use fgetcsv. Since you cannot import a file as a stream because the csv is a variable, then you should spoof the string as a file by using php://temp or php://memory first:

$fp = fopen("php://temp", 'r+');
fputs($fp, $csvText);
rewind($fp);

Then you will have no problem using fgetcsv:

$csv = [];
while ( ($data = fgetcsv($fp) ) !== FALSE ) {
    $csv[] = $data;
}

$data will be an array of a single csv line (which may include line breaks or commas, etc), as it should be.

Caveat: The memory limit of php://temp can be controlled by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes. (the default is 2 MB) http://www.php.net/manual/en/wrappers.php.php

You can write Bean Editors (details are in the Spring Docs) if you want to add further value and write to custom types.

Here is the solution:

d3.select("svg").remove();

This is a remove function provided by D3.js.

For whatever reason the above would not work for me. This is what did:

if (tabControl.SelectedTab.Name == "tabName" )
{
     .. do stuff
}

where tabControl.SelectedTab.Name is the name attribute assigned to the page in the tabcontrol itself.

For numerous reasons, No.

Why is explained in this MSDN post.

First, from a performance perspective the pointers get larger, so data structures get larger, and the processor cache stays the same size. That basically results in a raw speed hit (your mileage may vary). So you start in a hole and you have to dig yourself out of that hole by using the extra memory above 4G to your advantage. In Visual Studio this can happen in some large solutions but I think a preferable thing to do is to just use less memory in the first place. Many of VS’s algorithms are amenable to this. Here’s an old article that discusses the performance issues at some length: https://docs.microsoft.com/archive/blogs/joshwil/should-i-choose-to-take-advantage-of-64-bit

Secondly, from a cost perspective, probably the shortest path to porting Visual Studio to 64 bit is to port most of it to managed code incrementally and then port the rest. The cost of a full port of that much native code is going to be quite high and of course all known extensions would break and we’d basically have to create a 64 bit ecosystem pretty much like you do for drivers. Ouch.

FAT32 along with FAT16 and FAT12 are File System Types, but vfat along with umsdos and msdos are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos driver don't have long filenames (they are 8.3 format). vfat is the most common driver for mounting FAT32 file systems nowadays.

Source: this wikipedia article

Output of commands like df and lsblk indeed show vfat as the File System Type. But sudo file -sL /dev/<partition> shows FAT (32 bit) if a File System is FAT32.

You can confirm vfat is a module and not a File System Type by running modinfo vfat.

You could either access the element’s value by its name:

document.getElementsByName("textbox1"); // returns a list of elements with name="textbox1"
document.getElementsByName("textbox1")[0] // returns the first element in DOM with name="textbox1"

So:

<input name="buttonExecute" onclick="execute(document.getElementsByName('textbox1')[0].value)" type="button" value="Execute" />

Or you assign an ID to the element that then identifies it and you can access it with getElementById:

<input name="textbox1" id="textbox1" type="text" />
<input name="buttonExecute" onclick="execute(document.getElementById('textbox1').value)" type="button" value="Execute" />

you want these four lines of code in your Run.bat:

@echo off          //this makes it so you have an empty cmd window on startup
javac Main.java    //this compiles the .java into a .class
java Main          // this runs the .class file
pause              //this prevents the window from instantly closing after program end

As the other answers state there is no way getting query string parameters using servlet api.

So, I think the best way to get query parameters is parsing the query string yourself. ( It is more complicated iterating over parameters and checking if query string contains the parameter)

I wrote below code to get query string parameters. Using apache StringUtils and ArrayUtils which supports CSV separated query param values as well.

Example: username=james&username=smith&password=pwd1,pwd2 will return

password : [pwd1, pwd2] (length = 2)

username : [james, smith] (length = 2)

public static Map<String, String[]> getQueryParameters(HttpServletRequest request) throws UnsupportedEncodingException {
    Map<String, String[]> queryParameters = new HashMap<>();
    String queryString = request.getQueryString();
    if (StringUtils.isNotEmpty(queryString)) {
        queryString = URLDecoder.decode(queryString, StandardCharsets.UTF_8.toString());
        String[] parameters = queryString.split("&");
        for (String parameter : parameters) {
            String[] keyValuePair = parameter.split("=");
            String[] values = queryParameters.get(keyValuePair[0]);
            //length is one if no value is available.
            values = keyValuePair.length == 1 ? ArrayUtils.add(values, "") :
                    ArrayUtils.addAll(values, keyValuePair[1].split(",")); //handles CSV separated query param values.
            queryParameters.put(keyValuePair[0], values);
        }
    }
    return queryParameters;
}

Have a look at the UUID class bundled with Java 5 and later.

For example:

• If you want a random UUID you can use the randomUUID method.
• If you want a UUID initialized to a specific value you can use the UUID constructor or the fromString method.

There might be answers to this question, but you may want to see these migrations to PHP 7

Mmm first your id attributes must be unique, your code is likely to be

<form>
<input class='roles' name='roles' type='checkbox' value='1' />
<input class='roles' name='roles' type='checkbox' value='2' />
<input class='roles' name='roles' type='checkbox' value='3' />
<input class='roles' name='roles' type='checkbox' value='4' />
<input class='roles' name='roles' type='checkbox' value='5' />
<input type='submit' value='submit' />
</form>

For your problem :

if($('.roles:checkbox:checked').length == 0)
  // no checkbox checked, do something...
else
  // at least one checkbox checked...

BUT, remember that a JavaScript form validation is only indicative, all validations MUST be done server-side.

try this code below :

var currentLocation = document.location;
muzLoc = String(currentLocation).substring(0,45);
prodLoc = String(currentLocation).substring(0,48); 
techLoc = String(currentLocation).substring(0,47);

Visual Studio For Mac

None of the other solutions worked on Visual Studio for Mac

If you are using NUnit, you can add a small .NET Console Project to your solution, and then reference the project you wish to test in the References of that new Console Project.

Whatever you were doing in your [Test()] methods can be done in the Main of the console application in this fashion:

class MainClass
{
    public static void Main(string[] args)
    {
        Console.WriteLine("Console");

        // Reproduce the unit test
        var classToTest = new ClassToTest();
        var expected = 42;
        var actual = classToTest.MeaningOfLife();
        Console.WriteLine($"Pass: {expected.Equals(actual)}, expected={expected}, actual={actual}");
    }
}

You are free to use Console.Write and Console.WriteLine in your code under these circumstances.

A couple of things:

1. Your regexes need to be anchored by separators* or you'll match partial words, as is the case now
2. You're not using the proper syntax for a non-capturing group. It's (?: not (:?

If you address the first problem, you won't need groups at all.

*That is, a blank or beginning/end of string.

http://rolandtapken.de/blog/2012-04/java-process-httpproxyuser-and-httpproxypassword says:

Other suggest to use a custom default Authenticator. But that's dangerous because this would send your password to anybody who asks.

This is relevant if some http/https requests don't go through the proxy (which is quite possible depending on configuration). In that case, you would send your credentials directly to some http server, not to your proxy.

He suggests the following fix.

// Java ignores http.proxyUser. Here come's the workaround.
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        if (getRequestorType() == RequestorType.PROXY) {
            String prot = getRequestingProtocol().toLowerCase();
            String host = System.getProperty(prot + ".proxyHost", "");
            String port = System.getProperty(prot + ".proxyPort", "80");
            String user = System.getProperty(prot + ".proxyUser", "");
            String password = System.getProperty(prot + ".proxyPassword", "");

            if (getRequestingHost().equalsIgnoreCase(host)) {
                if (Integer.parseInt(port) == getRequestingPort()) {
                    // Seems to be OK.
                    return new PasswordAuthentication(user, password.toCharArray());  
                }
            }
        }
        return null;
    }  
});

I haven't tried it yet, but it looks good to me.

I modified the original version slightly to use equalsIgnoreCase() instead of equals(host.toLowerCase()) because of this: http://mattryall.net/blog/2009/02/the-infamous-turkish-locale-bug and I added "80" as the default value for port to avoid NumberFormatException in Integer.parseInt(port).

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

Updated accepted answer to angular 7.0.1 on stackblitz here: https://stackblitz.com/edit/angular-inputsetter?embed=1&file=src/app/app.component.ts

thank you @thierry-templier!

I find the double-bracket version of test makes writing logic tests more natural:

if [[ -d "${DIRECTORY}" && ! -L "${DIRECTORY}" ]] ; then
    echo "It's a bona-fide directory"
fi

The accepted answer gives an example of using the newest file in a command and then exiting. If you need to do this in a bat file with other complex operations you can use the following to store the file name of the newest file in a variable:

FOR /F "delims=|" %%I IN ('DIR "*.*" /B /O:D') DO SET NewestFile=%%I

Now you can reference %NewestFile% throughout the rest of your bat file.

For example here is what we use to get the latest version of a database .bak file from a directory, copy it to a server, and then restore the db:

:Variables
SET DatabaseBackupPath=\\virtualserver1\Database Backups

echo.
echo Restore WebServer Database
FOR /F "delims=|" %%I IN ('DIR "%DatabaseBackupPath%\WebServer\*.bak" /B /O:D') DO SET NewestFile=%%I
copy "%DatabaseBackupPath%\WebServer\%NewestFile%" "D:\"

sqlcmd -U <username> -P <password> -d master -Q ^
"RESTORE DATABASE [ExampleDatabaseName] ^
FROM  DISK = N'D:\%NewestFile%' ^
WITH  FILE = 1,  ^
MOVE N'Example_CS' TO N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Example.mdf',  ^
MOVE N'Example_CS_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Example_1.LDF',  ^
NOUNLOAD,  STATS = 10"

I ran into a similar issue today - my ruby version didn't match my rvm installs.

> ruby -v
ruby 2.0.0p481

> rvm list
rvm rubies
   ruby-2.1.2 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
   ruby-2.2.3 [ x86_64 ]

Also, rvm current failed.

> rvm current
Warning! PATH is not properly set up, '/Users/randallreed/.rvm/gems/ruby-2.2.1/bin' is not at first place...

The error message recommended this useful command, which resolved the issue for me:

> rvm get stable --auto-dotfiles

I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.

This is to make the variable of Optional type. Otherwise declared variables shows "undefined" if this variable is not used.

export interface ISearchResult {  
  title: string;  
  listTitle:string;
  entityName?: string,
  lookupName?:string,
  lookupId?:string  
}

You need first to cut the string in how many pieces you want. Then replace the part that you want:

 $text = 'this is the test for string.';
 $text = substr($text, 0, 10);
 echo $text = str_replace(" ", "_", $text);

This will output:

this_is_th

Use:

make:model {{SingularName}}

e.g

make:model Video

RSA
RSA encryption and decryption are commutative
hence it may be used directly as a digital signature scheme
given an RSA scheme {(e,R), (d,p,q)}
to sign a message M, compute:
S = M power d (mod R)
to verify a signature, compute:
M = S power e(mod R) = M power e.d(mod R) = M(mod R)

RSA can be used both for encryption and digital signatures, simply by reversing the order in which the exponents are used: the secret exponent (d) to create the signature, the public exponent (e) for anyone to verify the signature. Everything else is identical.

DSA (Digital Signature Algorithm)
DSA is a variant on the ElGamal and Schnorr algorithms. It creates a 320 bit signature, but with 512-1024 bit security again rests on difficulty of computing discrete logarithms has been quite widely accepted.

DSA Key Generation
firstly shared global public key values (p,q,g) are chosen:
choose a large prime p = 2 power L
where L= 512 to 1024 bits and is a multiple of 64
choose q, a 160 bit prime factor of p-1
choose g = h power (p-1)/q
for any h<p-1, h(p-1)/q(mod p)>1
then each user chooses a private key and computes their public key:
choose x<q
compute y = g power x(mod p)

DSA key generation is related to, but somewhat more complex than El Gamal. Mostly because of the use of the secondary 160-bit modulus q used to help speed up calculations and reduce the size of the resulting signature.

DSA Signature Creation and Verification

to sign a message M
generate random signature key k, k<q
compute
r = (g power k(mod p))(mod q)
s = k-1.SHA(M)+ x.r (mod q)
send signature (r,s) with message

to verify a signature, compute:
w = s-1(mod q)
u1= (SHA(M).w)(mod q)
u2= r.w(mod q)
v = (g power u1.y power u2(mod p))(mod q)
if v=r then the signature is verified

Signature creation is again similar to ElGamal with the use of a per message temporary signature key k, but doing calc first mod p, then mod q to reduce the size of the result. Note that the use of the hash function SHA is explicit here. Verification also consists of comparing two computations, again being a bit more complex than, but related to El Gamal.
Note that nearly all the calculations are mod q, and hence are much faster.
But, In contrast to RSA, DSA can be used only for digital signatures

DSA Security
The presence of a subliminal channel exists in many schemes (any that need a random number to be chosen), not just DSA. It emphasises the need for "system security", not just a good algorithm.

Another pure Bash solution:

while IFS=':' read a b ; do
  echo "$a"
done < "$infile" > "$outfile"

Whatever is specified in the command in docker-compose.yml should get appended to the entrypoint defined in the Dockerfile, provided entrypoint is defined in exec form in the Dockerfile.

If the EntryPoint is defined in shell form, then any CMD arguments will be ignored.

It depends on the jQuery selector that you use. Since id should be unique within the DOM, the first one would be simple:

$('#Comanda').hide();

The second one might require something more, depending on the other elements and how to uniquely identify it. If the name of that particular input is unique, then this would work:

$('input[name="Vizualizeaza"]').hide();

Mark color: #005580; as color: #005580 !important;.

It will override default bootstrap hover.

I got the same error when I added the applicationinitialization module with lots of initializationpages and deployed it on Azure app. The issue turned out to be duplicate entries in my applicationinitialization module. I din't see any errors in the logs so it was hard to troubleshoot. Below is an example of the error code:

  <configuration>
  <system.webServer>
    <applicationInitialization doAppInitAfterRestart="true" skipManagedModules="true">
      <add initializationPage="/init1.aspx?call=2"/>
      <add initializationPage="/init1.aspx?call=2" />
    </applicationInitialization>
  </system.webServer>

Make sure there are no duplicate entries because those will be treated as duplicate keys which are not allowed and will result in "Cannot add duplicate collection entry" error for web.config.

You shouldn't design your application based on specific lifetimes of access tokens. Just assume they are (very) short lived.

However, after a successful completion of the OAuth2 installed application flow, you will get back a refresh token. This refresh token never expires, and you can use it to exchange it for an access token as needed. Save the refresh tokens, and use them to get access tokens on-demand (which should then immediately be used to get access to user data).

EDIT: My comments above notwithstanding, there are two easy ways to get the access token expiration time:

1. It is a parameter in the response (expires_in)when you exchange your refresh token (using /o/oauth2/token endpoint). More details.

2. There is also an API that returns the remaining lifetime of the access_token:

   https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}

   This will return a json array that will contain an expires_in parameter, which is the number of seconds left in the lifetime of the token.

You can save it as follow if you have Pandas Dataframe

   df.to_csv(r'/dir/filename.csv')

You should look at MoSync too, MoSync gives you standard C/C++, easy-to-use well-documented APIs, and a full-featured Eclipse-based IDE. Its now a open sourced IDE still pretty cool but not maintained anymore.

For me it was a case sensitivity issue. My local branch was Version_feature2 instead of Version_Feature2. I re-checked out my branch using the correct casing and then git pull worked.

WHY

As mentioned by @Sheepy, the reason why it doesn't work is that java.util.logging.Logger has a root logger that defaults to Level.INFO, and the ConsoleHandler attached to that root logger also defaults to Level.INFO. Therefore, in order to see the FINE (, FINER or FINEST) output, you need to set the default value of the root logger and its ConsoleHandler to Level.FINE as follows:

Logger.getLogger("").setLevel(Level.FINE);
Logger.getLogger("").getHandlers()[0].setLevel(Level.FINE);

The problem of your Update (solution)

As mentioned by @mins, you will have the messages printed twice on the console for INFO and above: first by the anonymous logger, then by its parent, the root logger which also has a ConsoleHandler set to INFO by default. To disable the root logger, you need to add this line of code: logger.setUseParentHandlers(false);

There are other ways to prevent logs from being processed by default Console handler of the root logger mentioned by @Sheepy, e.g.:

Logger.getLogger("").getHandlers()[0].setLevel( Level.OFF );

But Logger.getLogger("").setLevel( Level.OFF ); won't work because it only blocks the message passed directly to the root logger, not the message comes from a child logger. To illustrate how the Logger Hierarchy works, I draw the following diagram:

public void setLevel(Level newLevel) set the log level specifying which message levels will be logged by this logger. Message levels lower than this value will be discarded. The level value Level.OFF can be used to turn off logging. If the new level is null, it means that this node should inherit its level from its nearest ancestor with a specific (non-null) level value.

Also, if you just installed localDB, you won't see the instance in the configuration manager. You would need to initiate it first, and then connect to it using server name (localdb)\mssqllocaldb. Source

Populate the text box values in the Page Init event as opposed to using the Postback.

protected void Page_Init(object sender, EventArgs e)
{
    DropDownTitle();
}

Certainly. Vim recognizes the \n character as a newline, so you can just search and replace. In command mode type:

:%s/\n/

I found this to occur when you mix ggplot charts with plot charts in the same session. Using the 'dev.off' solution suggested by Paul solves the issue.

This can be done using HTML5, but will only work in browsers that support it. Here's an example.

Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.

You can use array_merge($array1, $array2) to merge the associative array. Example:

$a1=array("red","green");
$a2=array("blue","yellow");
print_r(array_merge($a1,$a2));

Output:

Array ( [0] => red [1] => green [2] => blue [3] => yellow )

private OutputStream outputStream;
private InputStream inStream;

private void init() throws IOException {
    BluetoothAdapter blueAdapter = BluetoothAdapter.getDefaultAdapter();
    if (blueAdapter != null) {
        if (blueAdapter.isEnabled()) {
            Set<BluetoothDevice> bondedDevices = blueAdapter.getBondedDevices();

            if(bondedDevices.size() > 0) {
                Object[] devices = (Object []) bondedDevices.toArray();
                BluetoothDevice device = (BluetoothDevice) devices[position];
                ParcelUuid[] uuids = device.getUuids();
                BluetoothSocket socket = device.createRfcommSocketToServiceRecord(uuids[0].getUuid());
                socket.connect();
                outputStream = socket.getOutputStream();
                inStream = socket.getInputStream();
            }

            Log.e("error", "No appropriate paired devices.");
        } else {
            Log.e("error", "Bluetooth is disabled.");
        }
    }
}

public void write(String s) throws IOException {
    outputStream.write(s.getBytes());
}

public void run() {
    final int BUFFER_SIZE = 1024;
    byte[] buffer = new byte[BUFFER_SIZE];
    int bytes = 0;
    int b = BUFFER_SIZE;

    while (true) {
        try {
            bytes = inStream.read(buffer, bytes, BUFFER_SIZE - bytes);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Try accessing the placeholder attribute of the input and change its value like the following:

$('#some_input_id').attr('placeholder','New Text Here');

Can also clear the placeholder if required like:

$('#some_input_id').attr('placeholder','');

This works on Laravel 5:

{!!strlen($post->content) > 200 ? substr($post->content,0,200) : $post->content!!}

You can also customize the card theme globally with ThemeData.cardTheme:

MaterialApp(
  title: 'savvy',
  theme: ThemeData(
    cardTheme: CardTheme(
      shape: RoundedRectangleBorder(
        borderRadius: const BorderRadius.all(
          Radius.circular(8.0),
        ),
      ),
    ),
    // ...

Although there isn't a standard on the URL part, there is one standard for JavaScript. If you pass objects containing arrays to URLSearchParams, and call toString() on it, it will transform it into a comma separated list of items:

let data = {
  str: 'abc',
  arr: ['abc', 123]
}

new URLSearchParams(data).toString();
// ?str=abc&arr=abc,123 (with escaped characters)
