Also try to dos2unix the shell script, because sometimes it has Windows line endings and the shell does not recognize it.

$ dos2unix MigrateNshell.sh

This helps sometimes.

You are getting AttributeError because you're calling groups on None, which hasn't any methods.

regex.search returning None means the regex couldn't find anything matching the pattern from supplied string.

when using regex, it is nice to check whether a match has been made:

Result = re.search(SearchStr, htmlString)

if Result:
    print Result.groups()

Smultron is another good (and free) one.

I was confused about what 'add' really does. I just read a very enlightening paragraph from the book Git Pro that I'd like to add here, because it clarifies things

“It turns out that Git stages a file exactly as it is when you run the git add command. If you commit now, the version of benchmarks.rb as it was when you last ran the git add command is how it will go into the commit, not the version of the file as it looks in your working directory when you run git commit. If you modify a file after you run git add, you have to run git add again to stage the latest version of the file:”

You shouldn't call viewDidLoad method manually, Instead if you want to reload any data or any UI, you can use this:

override func viewDidLoad() {
    super.viewDidLoad();

    let myButton = UIButton()

    // When user touch myButton, we're going to call loadData method
    myButton.addTarget(self, action: #selector(self.loadData), forControlEvents: .TouchUpInside)

    // Load the data
    self.loadData();
}

func loadData() {
    // code to load data from network, and refresh the interface
    tableView.reloadData()
}

Whenever you want to reload the data and refresh the interface, you can call self.loadData()

tl;dr

for example if the startTime it's 23:00 and endTime 1:00 to get a duration of 2:00.

Not possible. If you have only time-of-day, the clock stops at midnight. Without the context of dates, how do we know if you mean 1 AM on the next day, next week, or next decade?

So going from 11 PM to 1 AM means moving backwards in time 22 hours, running the hands of the clock counterclockwise. See the result below, a negative twenty-two hours.

Duration.between(              // Represent a span of time a total number of seconds plus a fractional second in nanoseconds.
    LocalTime.of( 23 , 0 ) ,   // A time-of-day without a date and without a time zone. 
    LocalTime.of( 1 , 0 )      // A time-of-day clock stops at midnight. So getting to 1 AM from 11 PM means going backwards 22 hours.
)                              // Return a `Duration` object.
.toString()                    // Generate a `String` representing this span of time using standard ISO 8601 format: PnYnMnDTnHnMnS

PT-22H

Crossing midnight requires the larger context of date in addition to time-of-day (see below).

How do I measure time elapsed in Java?

1. Capture the current moment in UTC, with Instant.now().
2. Capture another such moment later.
3. Pass both to Duration.between.
4. (a) From the resulting Duration object, extract a number of 24-hour days, hours, minutes, seconds, and fractional second in nanoseconds by calling the various to…Part methods.
   (b) Or, call toString to generate a String in standard ISO 8601 format of PnYnMnDTnHnMnS.

Example code, using pair of Instant objects.

Duration.between(    // Represent a span of time a total number of seconds plus a fractional second in nanoseconds.
    then ,           // Some other `Instant` object, captured earlier with `Instant.now()`.
    Instant.now()    // Capture the current moment in UTC with a resolution as fine as nanoseconds, depending on the limits of your host computer hardware clock and operating system. Generally you will get current moment in microseconds (six decimal digits of fractional second) in Java 9, 10, and 11, but only milliseconds in Java 8. 
)                    // Return a `Duration` object.
.toString()          // Generate a `String` representing this span of time using standard ISO 8601 format: PnYnMnDTnHnMnS

New Technology In Java 8+

We have new technology for this now built into Java 8 and later, the java.time framework.

java.time

The java.time framework is defined by JSR 310, inspired by the highly successful Joda-Time project, extended by the ThreeTen-Extra project, and described in the Oracle Tutorial.

The old date-time classes such as java.util.Date/.Calendar bundled with the earliest versions of Java have proven to be poorly designed, confusing, and troublesome. They are supplanted by the java.time classes.

Resolution

Other answers discuss resolution.

The java.time classes have nanosecond resolution, up to nine digits of a decimal fraction of a second. For example, 2016-03-12T04:29:39.123456789Z.

Both the old java.util.Date/.Calendar classes and the Joda-Time classes have millisecond resolution (3 digits of fraction). For example, 2016-03-12T04:29:39.123Z.

In Java 8, the current moment is fetched with up to only millisecond resolution because of a legacy issue. In Java 9 and later, the current time can be determined up to nanosecond resolution provided your computer’s hardware clock runs so finely.

Time-Of-Day

If you truly want to work with only the time-of-day lacking any date or time zone, use the LocalTime class.

LocalTime sooner = LocalTime.of ( 17, 00 );
LocalTime later = LocalTime.of ( 19, 00 );

A Duration represents a span of time it terms of a count of seconds plus nanoseconds.

Duration duration = Duration.between ( sooner, later );

Dump to console.

System.out.println ( "sooner: " + sooner + " | later: " + later + " | duration: " + duration );

sooner: 17:00 | later: 19:00 | duration: PT2H

ISO 8601

Notice the default output of Duration::toString is in standard ISO 8601 format. In this format, the P marks the beginning (as in 'Period'), and the T separates any years-months-days portion from the hours-minutes-seconds portion.

Crossing Midnight

Unfortunately, working with time-of-day only gets tricky when you wrap around the clock crossing midnight. The LocalTime class handles this by assuming you want to go backwards to an earlier point in the day.

Using the same code as above but going from 23:00 to 01:00 results in a negative twenty-two hours (PT-22H).

LocalTime sooner = LocalTime.of ( 23, 0 );
LocalTime later = LocalTime.of ( 1, 0 );

sooner: 23:00 | later: 01:00 | duration: PT-22H

Date-Time

If you intend to cross midnight, it probably makes sense for you to be working with date-time values rather than time-of-day-only values.

Time Zone

Time zone is crucial to dates. So we specify three items: (1) the desired date, (2) desired time-of-day, and (3) the time zone as a context by which to interpret that date and time. Here we arbitrarily choose the time zone of the Montréal area.

If you define the date by only an offset-from-UTC, use a ZoneOffset with a OffsetDateTime. If you have a full time zone (offset plus rules for handling anomalies such as Daylight Saving Time), use a ZoneId with a ZonedDateTime.

LocalDate localDate = LocalDate.of ( 2016, 1, 23 );
ZoneId zoneId = ZoneId.of ( "America/Montreal" );
ZonedDateTime sooner = ZonedDateTime.of ( localDate, LocalTime.of ( 23, 0 ), zoneId );

We specify the later time as next day at 1:00 AM.

ZonedDateTime later = ZonedDateTime.of ( localDate.plusDays ( 1 ), LocalTime.of ( 1, 0 ), zoneId );

We calculate the Duration in the same manner as seen above. Now we get the two hours expected by this Question.

Duration duration = Duration.between ( sooner, later );

Dump to console.

System.out.println ( "sooner: " + sooner + " | later: " + later + " | duration: " + duration );

sooner: 2016-01-23T23:00-05:00[America/Montreal] | later: 2016-01-24T01:00-05:00[America/Montreal] | duration: PT2H

Daylight Saving Time

If the date-times at hand had involved Daylight Saving Time (DST) or other such anomaly, the java.time classes would adjust as needed. Read class doc for details.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

An easier way is to make the table a server side control. You could use something similar to this:

Dim x As Integer
table1.Border = "1"

'Change the first 10 rows to have a black border
 For x = 1 To 10
     table1.Rows(x).BorderColor = "Black"
 Next

'Change the rest of the rows to white
 For x = 11 To 22
     table1.Rows(x).BorderColor = "White"
 Next

Just wanted to post the code in a cleaner format... originally posted by sam3344920

cd /D "%APPDATA%\Mozilla\Firefox\Profiles"
cd *.default
set ffile=%cd%
echo user_pref("network.proxy.http", "148.233.229.235 ");>>"%ffile%\prefs.js"
echo user_pref("network.proxy.http_port", 3128);>>"%ffile%\prefs.js"
echo user_pref("network.proxy.type", 1);>>"%ffile%\prefs.js"
set ffile=
cd %windir%

If someone wants to remove the proxy settings, here is some code that will do that for you.

cd /D "%APPDATA%\Mozilla\Firefox\Profiles"
cd *.default
set ffile=%cd%
type "%ffile%\prefs.js" | findstr /v "user_pref("network.proxy.type", 1);" >"%ffile%\prefs_.js"
rename "%ffile%\prefs.js" "prefs__.js"
rename "%ffile%\prefs_.js" "prefs.js"
del "%ffile%\prefs__.js"
set ffile=
cd %windir%

Explanation: The code goes and finds the perfs.js file. Then looks within it to find the line "user_pref("network.proxy.type", 1);". If it finds it, it deletes the file with the /v parameter. The reason I added the rename and delete lines is because I couldn't find a way to overwrite the file once I had removed the proxy line. I'm sure there is a more efficient/safer way of doing this...

You can configure individual ObjectMappers like this:

ObjectMapper mapper  = new ObjectMapper();
mapper.setVisibility(mapper.getSerializationConfig().getDefaultVisibilityChecker()
                .withFieldVisibility(JsonAutoDetect.Visibility.ANY)
                .withGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withSetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withCreatorVisibility(JsonAutoDetect.Visibility.NONE));

If you want it set globally, I usually access a configured mapper through a wrapper class.

I heard of RTM (The RT FAQ Manager). Never used it, however.

You may try these

 int selectedIndex = myComboBox.getSelectedIndex();

-or-

Object selectedObject = myComboBox.getSelectedItem();

-or-

String selectedValue = myComboBox.getSelectedValue().toString();

The command rglob will do an infinite recursion down the deepest sub-level of your directory structure. If you only want one level deep, then do not use it, however.

I realize the OP was talking about using glob.glob. I believe this answers the intent, however, which is to search all subfolders recursively.

The rglob function recently produced a 100x increase in speed for a data processing algorithm which was using the folder structure as a fixed assumption for the order of data reading. However, with rglob we were able to do a single scan once through all files at or below a specified parent directory, save their names to a list (over a million files), then use that list to determine which files we needed to open at any point in the future based on the file naming conventions only vs. which folder they were in.

Environment variables can be used to set spring properties as described in the documentation. So, to set the active profiles (spring.profiles.active) you can use the following code on Unix systems:

SPRING_PROFILES_ACTIVE=test gradle clean bootRun

And on Windows you can use:

SET SPRING_PROFILES_ACTIVE=test
gradle clean bootRun

I think you're looking for sys.path

import sys
print (sys.path)

The primary flag seems to only work for vagrant ssh for me.

In the past I have used the following method to hack around the issue.

TLDR; Visual Studio 2019 may simply need a restart.

I encountered this situation using projects based on Microsoft.NET.Sdk project.

<Project Sdk="Microsoft.NET.Sdk">

Specifically:

• Project1: targets .netstandard2.1
  • references Microsoft.Extensions.Logging.Console via Nuget
• Project2: targets .netstandard2.1
  • references Project1 via a Project reference
• Project2Tests: targets .netcoreapp3.1
  • references Project2 via a Project reference

At test execution, I received the error messaging indicating that Microsoft.Extensions.Logging.Console could not be found, and it was indeed not in the output directory.

I decided to work around the issue by adding Microsoft.Extensions.Logging.Console to Project2, only to discover that Visual Studio's Nuget Manager did not list Microsoft.Extensions.Logging.Console as installed in Project1, despite it's presence in the Project1.csproj file.

A simple shut down and restart of Visual Studio resolved the problem without the need to add an extra reference. Perhaps this will save someone 45 minutes of lost productivity :-)

Now suppose there is an action for redux as:

export function addTodo(text) {
  return {
    type: ADD_TODO,
    text
  }
}

When you do import it,

import {addTodo} from './actions';

class Greeting extends React.Component {

    handleOnClick = () => {
        this.props.onTodoClick(); // This prop acts as key to callback prop for mapDispatchToProps
    }

    render() {
        return <button onClick={this.handleOnClick}>Hello Redux</button>;
    }
}

const mapDispatchToProps = dispatch => {
    return {
      onTodoClick: () => { // handles onTodoClick prop's call here
        dispatch(addTodo())
      }
    }
}

export default connect(
    null,
    mapDispatchToProps
)(Greeting);

As function name says mapDispatchToProps(), map dispatch action to props(our component's props)

So prop onTodoClick is a key to mapDispatchToProps function which delegates furthere to dispatch action addTodo.

Also if you want to trim the code and bypass manual implementation, then you can do this,

import {addTodo} from './actions';
class Greeting extends React.Component {

    handleOnClick = () => {
        this.props.addTodo();
    }

    render() {
        return <button onClick={this.handleOnClick}>Hello Redux</button>;
    }
}

export default connect(
    null,
    {addTodo}
)(Greeting);

Which exactly means

const mapDispatchToProps = dispatch => {
    return {
      addTodo: () => { 
        dispatch(addTodo())
      }
    }
}

There are a lot of right answers here depending on what you are trying to accomplish; here's my attempt at providing a comprehensive answer:

Both the Request and Response objects contain Cookies properties, which are HttpCookieCollection objects.

Request.Cookies:

• This collection contains cookies received from the client
• This collection is read-only
• If you attempt to access a non-existent cookie from this collection, you will receive a null value.

Response.Cookies:

• This collection contains only cookies that have been added by the server during the current request.
• This collection is writeable
• If you attempt to access a non-existent cookie from this collection, you will receive a new cookie object; If the cookie that you attempted to access DOES NOT exist in the Request.Cookies collection, it will be added (but if the Request.Cookies object already contains a cookie with the same key, and even if it's value is stale, it will not be updated to reflect the changes from the newly-created cookie in the Response.Cookies collection.

Solutions

If you want to check for the existence of a cookie from the client, do one of the following

• Request.Cookies["COOKIE_KEY"] != null
• Request.Cookies.Get("COOKIE_KEY") != null
• Request.Cookies.AllKeys.Contains("COOKIE_KEY")

If you want to check for the existence of a cookie that has been added by the server during the current request, do the following:

• Response.Cookies.AllKeys.Contains("COOKIE_KEY") (see here)

Attempting to check for a cookie that has been added by the server during the current request by one of these methods...

• Response.Cookies["COOKIE_KEY"] != null
• Response.Cookies.Get("COOKIE_KEY") != null (see here)

...will result in the creation of a cookie in the Response.Cookies collection and the state will evaluate to true.

try the !important argument to make sure the CSS is not conflicting with any other styles you have specified. Also using a reset.css is good before you add your own styles.

select#wgmstr {
    max-width: 50px;
    min-width: 50px;
    width: 50px !important;
}

or

<select name="wgtmsr" id="wgtmsr" style="width: 50px !important; min-width: 50px; max-width: 50px;">

When I find myself thinking about using Manager or Helper in a class name, I consider it a code smell that means I haven't found the right abstraction yet and/or I'm violating the single responsibility principle, so refactoring and putting more effort into design often makes naming much easier.

But even well-designed classes don't (always) name themselves, and your choices partly depend on whether you're creating business model classes or technical infrastructure classes.

Business model classes can be hard, because they're different for every domain. There are some terms I use a lot, like Policy for strategy classes within a domain (e.g., LateRentalPolicy), but these usually flow from trying to create a "ubiquitous language" that you can share with business users, designing and naming classes so they model real-world ideas, objects, actions, and events.

Technical infrastructure classes are a bit easier, because they describe domains we know really well. I prefer to incorporate design pattern names into the class names, like InsertUserCommand, CustomerRepository, or SapAdapter. I understand the concern about communicating implementation instead of intent, but design patterns marry these two aspects of class design - at least when you're dealing with infrastructure, where you want the implementation design to be transparent even while you're hiding the details.

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.

i did with

"start": "nodemon --watch 'src/**/*.ts' --ignore 'src/**/*.spec.ts' --exec ts-node src/index.ts"

and yarn start.. ts-node not like 'ts-node'

We can add "AwaitTerminationSeconds" property for both taskExecutor and taskScheduler as below,

<property name="awaitTerminationSeconds" value="${taskExecutor .awaitTerminationSeconds}" />

<property name="awaitTerminationSeconds" value="${taskScheduler .awaitTerminationSeconds}" />

Documentation for "waitForTasksToCompleteOnShutdown" property says, when shutdown is called

"Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property."

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/concurrent/ExecutorConfigurationSupport.html#setWaitForTasksToCompleteOnShutdown-boolean-

So it is always advised to use waitForTasksToCompleteOnShutdown and awaitTerminationSeconds properties together. Value of awaitTerminationSeconds depends on our application.

How big is your sample? Here is another option to test your data against any distribution using OpenTURNS library. In the example below, I generate a sample x of 1.000.000 numbers from a Uniform distribution and test it against a Normal distribution. You can replace x by your data if you reshape it as x= [[x1], [x2], .., [xn]]

import openturns as ot

x = ot.Uniform().getSample(1000000)
g = ot.VisualTest.DrawQQplot(x, ot.Normal())
g

In my Jupyter Notebook, I see:

If you are writing a script, you can do it more properly

from openturns.viewer import View`
import matplotlib.pyplot as plt
View(g)
plt.show()

You can find what you're looking for in the information schema: SQL Server 2005 System Tables and Views I think you need SQL Server 2005 or higher to use the approach described in this article, but a similar method can be used for earlier versions.

UPDATE: As of Bootstrap 3.0, the input-* classes described below for setting the width of input elements were removed. Instead use the col-* classes to set the width of input elements. Examples are provided in the documentation.

In Bootstrap 2.3, you'd use the input classes for setting the width.

<textarea class="input-mini"></textarea>
<textarea class="input-small"></textarea>
<textarea class="input-medium"></textarea>
<textarea class="input-large"></textarea>
<textarea class="input-xlarge"></textarea>
<textarea class="input-xxlarge"></textarea>?
<textarea class="input-block-level"></textarea>?

Do a find for "Control sizing" for examples in the documentation.

But for height I think you'd still use the rows attribute.

Have a look here.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

Wrote a glitch workspace that iterates over all the codepoints and emit the character if eval('var ' + String.fromCodePoint(#) + ' = 1') works.

It just keeps going, and going, and going....

We can also use col-md-offset like this, it would save us from an extra divs code. So instead of three divs we can do by using only one div:

<div class="col-md-4 col-md-offset-4">Centered content</div>

simple query this query select all record from table where email is unique:

select distinct email,* from table_name

I hit the same problem on my laptop(win 10) with Wireshark(version 3.2.0), and I tried all the above solutions but unfortunately don't help.

So,

I uninstall the Wireshark bluntly and reinstall it.

After that, this problem solved.

Putting the solution here, and wish it may help someone......

It's not a good idea when you want your images and style information to be cached separately. Also if you encode a large image or a significant number of images in to your css file it will take the browser longer to download the file leaving your site without any of the style information until the download completes. For small images that you don't intend on changing often if ever it is a fine solution.

as far as generating the base64 encoding:

• http://b64.io/
• http://www.motobit.com/util/base64-decoder-encoder.asp (upload)
• http://www.greywyvern.com/code/php/binary2base64 (from link with little tutorials underneath)

Internet Explorer has a maximum number of code lines for style sheet recognition.

This is Bootstrap navbar style rule that set the float property for navbar items:

.navbar-nav > li {
    float: left;
}

That rule in Bootstrap 3 (probably in early versions too) is on line 5247.

As it says here: Internet Explorer's CSS rules limits, a sheet may contain up to 4095 lines.

I tried with CSS, and or you need to use display: table or you need to use new css that is not yet supported on most browsers (2016).

So, I wrote a jquery plugin to do it for us, I am happy to share it:

If you are going to call relative.py directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path list.
Here is how it should work:

# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')

# Now you can do imports from one directory top cause it is in the sys.path
import parent

# And even like this:
from parent import Parent

If you think the above can cause some kind of inconsistency you can use this instead:

sys.path.append(sys.path[0] + "/..")

sys.path[0] refers to the path that the entry point was ran from.

http://php.net/manual/en/function.unlink.php

Unlink can safely remove a single file; just make sure the file you are removing it actually a file and not a directory ('.' or '..')

if (is_file($filepath))
  {
    unlink($filepath);
  }

Just type java -version in your console.

If a 64 bit version is running, you'll get a message like:

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

A 32 bit version will show something similar to:

java version "1.6.0_41"
Java(TM) SE Runtime Environment (build 1.6.0_41-b02)
Java HotSpot(TM) Client VM (build 20.14-b01, mixed mode, sharing)

Note Client instead of 64-Bit Server in the third line. The Client/Server part is irrelevant, it's the absence of the 64-Bit that matters.

If multiple Java versions are installed on your system, navigate to the /bin folder of the Java version you want to check, and type java -version there.

So, not directly related but this is the first question that appears when you try to find how to terminate a process running from a specific folder using Python.

It also answers the question in a way(even though it is an old one with lots of answers).

While creating a faster way to scrape some government sites for data I had an issue where if any of the processes in the pool got stuck they would be skipped but still take up memory from my computer. This is the solution I reached for killing them, if anyone knows a better way to do it please let me know!

import pandas as pd
import wmi
from re import escape
import os

def kill_process(kill_path, execs):
    f = wmi.WMI()
    esc = escape(kill_path)
    temp = {'id':[], 'path':[], 'name':[]}
    for process in f.Win32_Process():
        temp['id'].append(process.ProcessId)
        temp['path'].append(process.ExecutablePath)
        temp['name'].append(process.Name)
    temp = pd.DataFrame(temp)
    temp = temp.dropna(subset=['path']).reset_index().drop(columns=['index'])
    temp = temp.loc[temp['path'].str.contains(esc)].loc[temp.name.isin(execs)].reset_index().drop(columns=['index'])
    [os.system('taskkill /PID {} /f'.format(t)) for t in temp['id']]

I would write something like this:

ngOnInit() {
this.routed = this.router.events.map( event => event instanceof NavigationStart )
  .subscribe(() => {
  } );
}

ngOnDestroy() {
this.routed.unsubscribe();
}

The default specifier depends upon context.

For classes, and interface declarations, the default is package private. This falls between protected and private, allowing only classes in the same package access. (protected is like this, but also allowing access to subclasses outside of the package.)

class MyClass   // package private
{
   int field;    // package private field

   void calc() {  // package private method

   }
}

For interface members (fields and methods), the default access is public. But note that the interface declaration itself defaults to package private.

interface MyInterface  // package private
{
   int field1;         // static final public

   void method1();     // public abstract
}

If we then have the declaration

public interface MyInterface2 extends MyInterface
{

}

Classes using MyInterface2 can then see field1 and method1 from the super interface, because they are public, even though they cannot see the declaration of MyInterface itself.

well here is common usage of getter setter in actual use case,

public class OrderItem 
{
public int Id {get;set;}
public int quantity {get;set;}
public int Price {get;set;}
public int TotalAmount {get {return this.quantity *this.Price;}set;}
}

you have already forwarded the response in catch block:

RequestDispatcher dd = request.getRequestDispatcher("error.jsp");

dd.forward(request, response);

so, you can not again call the :

response.sendRedirect("usertaskpage.jsp");

because it is already forwarded (committed).

So what you can do is: keep a string to assign where you need to forward the response.

    String page = "";
    try {

    } catch (Exception e) {
      page = "error.jsp";
    } finally {
      page = "usertaskpage.jsp";
    }

RequestDispatcher dd=request.getRequestDispatcher(page);
dd.forward(request, response);

1. I personally prefere .update for its convenience. But execsql will work same.
2. You are right with your guess that the problem is your content values. You should create a ContentValue Object and put the values for your database row there.

This code should fix your example:

 ContentValues data=new ContentValues();
 data.put("Field1","bob");
 data.put("Field2",19);
 data.put("Field3","male");
 DB.update(Tablename, data, "_id=" + id, null);

Option 1:

NSString *haystack = @"value:hello World:value";
NSString *haystackPrefix = @"value:";
NSString *haystackSuffix = @":value";
NSRange needleRange = NSMakeRange(haystackPrefix.length,
                                  haystack.length - haystackPrefix.length - haystackSuffix.length);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle); // -> "hello World"

Option 2:

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"^value:(.+?):value$" options:0 error:nil];
NSTextCheckingResult *match = [regex firstMatchInString:haystack options:NSAnchoredSearch range:NSMakeRange(0, haystack.length)];
NSRange needleRange = [match rangeAtIndex: 1];
NSString *needle = [haystack substringWithRange:needleRange];

This one might be a bit over the top for your rather trivial case though.

Option 3:

NSString *needle = [haystack componentsSeparatedByString:@":"][1];

This one creates three temporary strings and an array while splitting.

All snippets assume that what's searched for is actually contained in the string.

For swift 3.0

if let url = URL(string: "tel://\(number)"), UIApplication.shared.canOpenURL(url) {
    if #available(iOS 10, *) {
        UIApplication.shared.open(url)
    } else {
        UIApplication.shared.openURL(url)
    }
}
else {
    print("Your device doesn't support this feature.")
}

You could type "prop" and then press tab twice. That will generate the following.

public TYPE Type { get; set; }

Then you change "TYPE" and "Type":

public string myString {get; set;}

You can also get the full property typing "propfull" and then tab twice. That would generate the field and the full property.

private int myVar;

public int MyProperty
{
    get { return myVar;}
    set { myVar = value;}
}

If your shell supports it, would something like this work ?

javac com/**/*.java 

If your shell does not support **, then maybe

javac com/*/*/*.java

works (for all packages with 3 components - adapt for more or less).

Just a simplified version of @T.J. Crowder and @RegarBoy's answers.

Less is more in my opinion.

Check out onmousemove event for more info about the event.

There's a new value of posX and posY every time the mouse moves according to the horizontal and vertical coordinates.

<!DOCTYPE html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Example Mouse Tracker</title>
      <style>    
        body {height: 3000px;}
        .dot {width: 2px;height: 2px;background-color: black;position: absolute;}
      </style>
    </head>
    <body>
    <p>Mouse tracker</p>
    <script>
    onmousemove = function(e){
        //Logging purposes
        console.log("mouse location:", e.clientX, e.clientY);

        //meat and potatoes of the snippet
        var pos = e;
        var dot;
        dot = document.createElement('div');
        dot.className = "dot";
        dot.style.left = pos.x + "px";
        dot.style.top = pos.y + "px";
        document.body.appendChild(dot);
    }      
    </script>
    </body>
    </html>

Use like this,

 $( "#id" ).prop( "disabled", true );

 $( "#id" ).prop( "disabled", false );

Mostly a problem with an invalid layout file. Open the 'Problems' view and look for erros in XML layout files. Fix them and the R class will be recreated.

In my case there wasn't a real error. The problem view showed an error in a xml layout. The editor showed the xml error too. Just reformatting the xml using the auto formatter with 'ctrl-f' 'fixed' the xml 'error' and the R class was recreated.

You can do it with the HTMLWorker class (deprecated) like this:

import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter.getInstance(document, file);
    document.open();
    HTMLWorker htmlWorker = new HTMLWorker(document);
    htmlWorker.parse(new StringReader(k));
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

or using the XMLWorker, (download from this jar) using this code:

import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(k.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

I hope i am not too late, this solution here worked for me, i am using COMODO SSL, the above solutions seem invalid over time, my website lifetanstic.co.ke

Instead of contacting Comodo Support and gain a CA bundle file You can do the following:

When You get your new SSL cert from Comodo (by mail) they have a zip file attached. You need to unzip the zip-file and open the following files in a text editor like notepad:

AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt

Then copy the text of each ".crt" file and paste the texts above eachother in the "Certificate Authority Bundle (optional)" field.

After that just add the SSL cert as usual in the "Certificate" field and click at "Autofil by Certificate" button and hit "Install".

If you know this when the page is rendered, which it sounds like you do because the database has a value, it's better to disable it when rendered instead of JavaScript. To do that, just add the readonly attribute (or disabled, if you want to remove it from the form submission as well) to the <input>, like this:

<input type="text" disabled="disabled" />
//or...
<input type="text" readonly="readonly" />

Options>Advanced>connections

Uncheck the option :

Use port 80 and 443 as alternative....

Tomcat can work in 2 modes:

• BIO – blocking I/O (one thread per connection)
• NIO – non-blocking I/O (many more connections than threads)

Tomcat 7 is BIO by default, although consensus seems to be "don't use Bio because Nio is better in every way". You set this using the protocol parameter in the server.xml file.

• BIO will be HTTP/1.1 or org.apache.coyote.http11.Http11Protocol
• NIO will be org.apache.coyote.http11.Http11NioProtocol

If you're using BIO then I believe they should be more or less the same.

If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. The defaults are maxConnections=10,000 and maxThreads=200. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.

export a=$(script.sh)

Hope this helps. Note there are no spaces between variable and =. To echo the output

echo $a

First you compile the regex, then you have to use it with match, find, or some other method to actually run it against some input.

import os
import re
import shutil

def test():
    os.chdir("C:/Users/David/Desktop/Test/MyFiles")
    files = os.listdir(".")
    os.mkdir("C:/Users/David/Desktop/Test/MyFiles2")
    pattern = re.compile(regex_txt, re.IGNORECASE)
    for x in (files):
        with open((x), 'r') as input_file:
            for line in input_file:
                if pattern.search(line):
                    shutil.copy(x, "C:/Users/David/Desktop/Test/MyFiles2")
                    break

To grab the text from textfield-

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
      switch (self.currentIndex.row) {

            case 0:
                NSLog(@"%@",[NSString stringWithFormat:@"%@%@",textField.text,string]);//Take current word and previous text from textfield
                break;

            case 1:
                 NSLog(@"%@",[NSString stringWithFormat:@"%@%@",textField.text,string]);//Take current word and previous text from textfield
                break;

            case 2:
                 NSLog(@"%@",[NSString stringWithFormat:@"%@%@",textField.text,string]);//Take current word and previous text from textfield
                break;

            default:
                break;
        }
}

I have solved this by manually copying EntityFramework.SqlServer.dll file to the bin folder of the main application.

Solution 1

If we consider a JavaScript integer to be a value of maximum 4294967295 (i.e. Math.pow(2,32)-1), then the following short solution will perfectly work:

function isPositiveInteger(n) {
    return n >>> 0 === parseFloat(n);
}

DESCRIPTION:

1. Zero-fill right shift operator does three important things:
   • truncates decimal part
     • 123.45 >>> 0 === 123
   • does the shift for negative numbers
     • -1 >>> 0 === 4294967295
   • "works" in range of MAX_INT
     • 1e10 >>> 0 === 1410065408
     • 1e7 >>> 0 === 10000000
2. parseFloat does correct parsing of string numbers (setting NaN for non numeric strings)

TESTS:

"0"                     : true
"23"                    : true
"-10"                   : false
"10.30"                 : false
"-40.1"                 : false
"string"                : false
"1234567890"            : true
"129000098131766699.1"  : false
"-1e7"                  : false
"1e7"                   : true
"1e10"                  : false
"1edf"                  : false
" "                     : false
""                      : false

Solution 2

Another way is good for all numeric values which are valid up to Number.MAX_VALUE, i.e. to about 1.7976931348623157e+308:

function isPositiveInteger(n) {
    return 0 === n % (!isNaN(parseFloat(n)) && 0 <= ~~n);
}

DESCRIPTION:

1. !isNaN(parseFloat(n)) is used to filter pure string values, e.g. "", " ", "string";
2. 0 <= ~~n filters negative and large non-integer values, e.g. "-40.1", "129000098131766699";
3. (!isNaN(parseFloat(n)) && 0 <= ~~n) returns true if value is both numeric and positive;
4. 0 === n % (...) checks if value is non-float -- here (...) (see 3) is evaluated as 0 in case of false, and as 1 in case of true.

TESTS:

"0"                     : true
"23"                    : true
"-10"                   : false
"10.30"                 : false
"-40.1"                 : false
"string"                : false
"1234567890"            : true
"129000098131766699.1"  : false
"-1e10"                 : false
"1e10"                  : true
"1edf"                  : false
" "                     : false
""                      : false

DEMO: http://jsfiddle.net/5UCy4/14/

The previous version:

function isPositiveInteger(n) {
    return n == "0" || ((n | 0) > 0 && n % 1 == 0);
}

For some reason none of the above answers seemed to be addressing the case of the real first and only first child of the parent.

#element_id > .class_name:first-child

All the above answers will fail if you want to apply the style to only the first class child within this code.

<aside id="element_id">
  Content
  <div class="class_name">First content that need to be styled</div>
  <div class="class_name">
    Second content that don't need to be styled
    <div>
      <div>
        <div class="class_name">deep content - no style</div>
        <div class="class_name">deep content - no style</div>
        <div>
          <div class="class_name">deep content - no style</div>

            throw new ArgumentNullException("image");

        //create a new empty bitmap to hold rotated image
        Bitmap rotatedBmp = new Bitmap(image.Width, image.Height);
        rotatedBmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);

        //make a graphics object from the empty bitmap
        Graphics g = Graphics.FromImage(rotatedBmp);

        //Put the rotation point in the center of the image
        g.TranslateTransform(offset.X, offset.Y);

        //rotate the image
        g.RotateTransform(angle);

        //move the image back

        return rotatedBmp;
    }

CMP subtracts the operands and sets the flags. Namely, it sets the zero flag if the difference is zero (operands are equal).

TEST sets the zero flag, ZF, when the result of the AND operation is zero. If two operands are equal, their bitwise AND is zero when both are zero. TEST also sets the sign flag, SF, when the most significant bit is set in the result, and the parity flag, PF, when the number of set bits is even.

JE [Jump if Equals] tests the zero flag and jumps if the flag is set. JE is an alias of JZ [Jump if Zero] so the disassembler cannot select one based on the opcode. JE is named such because the zero flag is set if the arguments to CMP are equal.

So,

TEST %eax, %eax
JE   400e77 <phase_1+0x23>

jumps if the %eax is zero.

I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.

Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty().

if ( values > 0 ) {
    //you got a positive value
}else{
    //you got a negative or zero value    
}

Negative numbers mean that you count from the right instead of the left. So, list[-1] refers to the last element, list[-2] is the second-last, and so on.

FatJar can help you in this case.

In addition to the"Export as Jar" function which is included to Eclipse the Plug-In bundles all dependent JARs together into one executable jar.
The Plug-In adds the Entry "Build Fat Jar" to the Context-Menu of Java-projects

This is useful if your final exported jar includes other external jars.

If you have Ganymede, the Export Jar dialog is enough to export your resources from your project.

After Ganymede, you have:

SUM CASE using example:

    SELECT 
  DISTINCT(p.`ProductID`) AS ProductID,
  SUM(IF(p.`PaymentMethod`='Cash',Amount,0)) AS Cash_,
  SUM(IF(p.`PaymentMethod`='Check',Amount,0)) AS Check_,
  SUM(IF(p.`PaymentMethod`='Credit Card',Amount,0)) AS Credit_Card_,
  SUM( CASE PaymentMethod 
      WHEN 'Cash' THEN Amount
      WHEN 'Check' THEN Amount
      WHEN 'Credit Card' THEN Amount
     END) AS Total
FROM
  `payments` AS p 
GROUP BY p.`ProductID`;

    <item name="android:orientation">vertical</item>
</style>

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

You can filter all characters from the string that are not printable using string.printable, like this:

>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'

string.printable on my machine contains:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c

EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:

''.join(filter(lambda x: x in printable, s))

You can't rely on context menus because the user can deactivate it. Most websites want to use the feature to annoy the visitor.

The best and easy solution for solving this issue is pass your data from this function in controller.

$scope.trustSrcurl = function(data) 
{
    return $sce.trustAsResourceUrl(data);
}

I came across this SO question while searching for a similar problem. I had to build a 2D array and then replace some elements of each list (in 2D array) with elements from a dict. I then came across this SO question which helped me, maybe this will help other beginners to get around. The key trick was to initialize the 2D array as an numpy array and then using array[i,j] instead of array[i][j].

For reference this is the piece of code where I had to use this :

nd_array = []
for i in range(30):
    nd_array.append(np.zeros(shape = (32,1)))
new_array = []
for i in range(len(lines)):
    new_array.append(nd_array)
new_array = np.asarray(new_array)
for i in range(len(lines)):
    splits = lines[i].split(' ')
    for j in range(len(splits)):
        #print(new_array[i][j])
        new_array[i,j] = final_embeddings[dictionary[str(splits[j])]-1].reshape(32,1)

Now I know we can use list comprehension but for simplicity sake I am using a nested for loop. Hope this helps others who come across this post.

IntelliJ IDEA does not have an action to add imports. Rather it has the ability to do such as you type. If you enable the "Add unambiguous imports on the fly" in Settings > Editor > General > Auto Import, IntelliJ IDEA will add them as you type without the need for any shortcuts. You can also add classes and packages to exclude from auto importing to make a class you use heavily, that clashes with other classes of the same name, unambiguous.

For classes that are ambiguous (or is you prefer to have the "Add unambiguous imports on the fly" option turned off), just type the name of the class (just the name is OK, no need to fully qualify). Use code completion and select the particular class you want:

Notice the fully qualified names to the right. When I select the one I want and hit enter, IDEA will automatically add the import statement. This works the same if I was typing the name of a constructor. For static methods, you can even just keep typing the method you want. In the following screenshot, no "StringUtils" class is imported yet.

Alternatively, type the class name and then hit Alt+Enter or ?+Enter to "Show intention actions and quick-fixes" and then select the import option.

Although I've never used it, I think the Eclipse Code Formatter third party plug-in will do what you want. It lists "emulates Eclipse's imports optimizing" as a feature. See its instructions for more information. But in the end, I suspect you'll find the built in IDEA features work fine once you get use to their paradigm. In general, IDEA uses a "develop by intentions" concept. So rather than interrupting my development work to add an import statement, I just type the class I want (my intention) and IDEA automatically adds the import statement for the class for me.

In the source header you can declare:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
....

It is described in the PEP 0263:

Then you can use UTF-8 in strings:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

u = 'idzie waz waska drózka'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)

This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120).

In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8. Otherwise, you may have invisible characters that are not interpreted as UTF-8.

I have a mac for mobile development use and very often meet this problems. The source for this problems is the "platform independent" solutions, which doesn't care enough for mac and they don't have access to keychain, where are stored the certificates, .pem files and so on.

All I wanted is to not make any environment settings, nor command line, just simple GUI based clicks, like a regular user.

Half part was done with Eclipse Git plugin, second part (push to Github) was done with Mac Github

Nice and easy :)

All can be done with with that native appp if I would start to learn it, I just need the push functionality from him.

Hoping it will help a mac user once.

Add the following under @NgModule({})in 'app.module.ts' :

import {CUSTOM_ELEMENTS_SCHEMA} from `@angular/core`;

and then

schemas: [
    CUSTOM_ELEMENTS_SCHEMA
]

Your 'app.module.ts' should look like this:

import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';

@NgModule({
  declarations: [],
  imports: [],
  schemas: [ CUSTOM_ELEMENTS_SCHEMA],
  providers: [],
  bootstrap: [AppComponent]
})

export class AppModule { }

It is possible to use full C# 6.0 features in Visual Studio 2013 if you have Resharper.
You have to enable Resharper Build and voilá! In Resharper Options -> Build - enable Resharper Build and in "Use MSBuild.exe version" choose "Latest Installed"

This way Resharper is going to build your C# 6.0 Projects and will also not underline C# 6.0 code as invalid.

I am also using this although I have Visual Studio 2015 because:

1. Unit Tests in Resharper don't work for me with Visual Studio 2015 for some reason
2. VS 2015 uses a lot more memory than VS 2013.

I am putting this here, as I was looking for a solution for this problem for some time now and maybe it will help someone else.

you can't increase the heap size dynamically.

you can request to use more by using android:largeHeap="true" in the manifest.

also, you can use native memory (NDK & JNI) , so you actually bypass the heap size limitation.

here are some posts i've made about it:

• How to cache bitmaps into native memory

• JNI bitmap operations , for helping to avoid OOM when using large images

and here's a library i've made for it:

• https://github.com/AndroidDeveloperLB/AndroidJniBitmapOperations

You should set the android:exported attribute of the service to "true", in order to allow other components to invoke it. In the AndroidManifest.xml file, add the following attribute:

<service android:exported="true" ></service>

Then, you should be able to start the service via adb:

adb shell am startservice com.package.name/.YourServiceName

For more info about the android:exported attribute see this page.

While using vim to do it is perfectly possible, why don't you simply use iconv? I mean - loading text editor just to do encoding conversion seems like using too big hammer for too small nail.

Just:

iconv -f utf-16 -t utf-8 file.xml > file.utf8.xml

And you're done.

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

http://api.jquery.com/jQuery.post/

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

File uploading (most of this applies if sending plain text too if javascript can choose the name of the file) http://www.developershome.com/wap/wapUpload/wap_upload.asp?page=security https://www.owasp.org/index.php/Unrestricted_File_Upload

First make sure the PHP files themselves are UTF-8 encoded.

The meta tag is ignored by some browser. If you only use ASCII-characters, it doesn't matter anyway.

I have been trying all the answers here with no success. Here is the simplest way to do it with ms-appx

        ImageBrush myBrush = new ImageBrush();
        Image image = new Image();
        image.Source = new BitmapImage(new Uri(@"ms-appx:///Assets/background.jpg"));
        myBrush.ImageSource = image.Source;
        TheGrid.Background = myBrush;

Assets folder is in the first level of my project, so make sure to change the path as convenient.

I know this is an old thread but I have tried numerous things and fixed my issue using the following means..

I'm developing a cross platform app on Windows but to be used on Linux and Windows servers.

A MySQL database called "jtm" installed on both systems. For some reason, in my code I had the database name as "JTM". On Windows it worked fine, in fact on several Windows systems it flew along.

On Ubuntu I got the error above time and time again. I tested it out with the correct case in the code "jtm" and it works a treat.

Linux is obviously a lot less forgiving about case sensitivity (rightly so), whereas Windows makes allowances.

I feel a bit daft now but check everything. The error message is not the best but it does seem fixable if you persevere and get things right.

In Kotlin you can do as:

First, put this code in your layout

   <Spinner
            android:id="@+id/spinner"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"/>

Then you can do in onCreate() in Activity as ->

   val spinner = findViewById<Spinner>(R.id.spinner)
    val items = arrayOf("500g", "1kg", "2kg")
    val adapter = ArrayAdapter<String>(
        this,
        android.R.layout.simple_spinner_dropdown_item,
        items
    )
    spinner.setAdapter(adapter)

You can get listener from dropdown as:

 spinner.onItemSelectedListener = object : OnItemSelectedListener {
        override fun onItemSelected(
            arg0: AdapterView<*>?,
            arg1: View?,
            arg2: Int,
            arg3: Long
        ) {
            // Do what you want
            val items = spinner.selectedItem.toString()
            
        }

        override fun onNothingSelected(arg0: AdapterView<*>?) {}
    }

Since your example uses a generic List, I assume you don't need an index or unique constraint on your data. A List may contain duplicate values. If you want to insure a unique key, consider using a Dictionary<TKey, TValue>().

var list = new List<Tuple<int,string>>();

list.Add(Tuple.Create(1, "Andy"));
list.Add(Tuple.Create(1, "John"));
list.Add(Tuple.Create(3, "Sally"));

foreach (var item in list)
{
    Console.WriteLine(item.Item1.ToString());
    Console.WriteLine(item.Item2);
}

As noted by others, the official documentation is available here: WhatsApp.com FAQ: Android -> Chats -> How to use click to chat. The documentation states:

Example: https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale

BUT! Why don't we try copying that into a new tab in your browser and going there right now?

https://wa.me/text=testtesttesttest

Results: ERROR PAGE NOT FOUND.

What gives???

Fix it easily by using one of THESE format:

https://api.whatsapp.com/send?text=YourShareTextHere
https://api.whatsapp.com/send?text=YourShareTextHere&phone=123

No wa.me domain in this URL!

Here's an alternative solution to this question. My adapter:

    private class PagerAdapter extends FragmentPagerAdapter implements 
                    ViewPager.OnPageChangeListener, TabListener {

    private List<Fragment> mFragments = new ArrayList<Fragment>();
    private ViewPager mPager;
    private ActionBar mActionBar;

    private Fragment mPrimaryItem;

    public PagerAdapter(FragmentManager fm, ViewPager vp, ActionBar ab) {
        super(fm);
        mPager = vp;
        mPager.setAdapter(this);
        mPager.setOnPageChangeListener(this);
        mActionBar = ab;
    }

    public void addTab(PartListFragment frag) {
        mFragments.add(frag);
        mActionBar.addTab(mActionBar.newTab().setTabListener(this).
                            setText(frag.getPartCategory()));
    }

    @Override
    public Fragment getItem(int position) {
        return mFragments.get(position);
    }

    @Override
    public int getCount() {
        return mFragments.size();
    }

    /** (non-Javadoc)
     * @see android.support.v4.app.FragmentStatePagerAdapter#setPrimaryItem(android.view.ViewGroup, int, java.lang.Object)
     */
    @Override
    public void setPrimaryItem(ViewGroup container, int position,
            Object object) {
        super.setPrimaryItem(container, position, object);
        mPrimaryItem = (Fragment) object;
    }

    /** (non-Javadoc)
     * @see android.support.v4.view.PagerAdapter#getItemPosition(java.lang.Object)
     */
    @Override
    public int getItemPosition(Object object) {
        if (object == mPrimaryItem) {
            return POSITION_UNCHANGED;
        }
        return POSITION_NONE;
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        mPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) { }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) { }

    @Override
    public void onPageScrollStateChanged(int arg0) { }

    @Override
    public void onPageScrolled(int arg0, float arg1, int arg2) { }

    @Override
    public void onPageSelected(int position) {
        mActionBar.setSelectedNavigationItem(position);
    }

    /**
     * This method removes the pages from ViewPager
     */
    public void removePages() {
        mActionBar.removeAllTabs();

                    //call to ViewPage to remove the pages
        vp.removeAllViews();
        mFragments.clear();

        //make this to update the pager
        vp.setAdapter(null);
        vp.setAdapter(pagerAdapter);
    }
}

Code to remove and add dynamically

//remove the pages. basically call to method removeAllViews from `ViewPager`
pagerAdapter.removePages();

pagerAdapter.addPage(pass your fragment);

After the advice of Peri Hartman, it started to work after I set null do ViewPager adapter and put the adapter again after the views removed. Before this the page 0 doesnt showed its list contents.

Thanks.

Here's a TypeScript implementation of https://stackoverflow.com/a/21323330/916734. It also dries things up with functions, and allows for a optional digit offset.

export function round(rawValue: number | string, precision = 0, fractionDigitOffset = 0): number | string {
  const value = Number(rawValue);
  if (isNaN(value)) return rawValue;

  precision = Number(precision);
  if (precision % 1 !== 0) return NaN;

  let [ stringValue, exponent ] = scientificNotationToParts(value);

  let shiftExponent = exponentForPrecision(exponent, precision, Shift.Right);
  const enlargedValue = toScientificNotation(stringValue, shiftExponent);
  const roundedValue = Math.round(enlargedValue);

  [ stringValue, exponent ] = scientificNotationToParts(roundedValue);
  const precisionWithOffset = precision + fractionDigitOffset;
  shiftExponent = exponentForPrecision(exponent, precisionWithOffset, Shift.Left);

  return toScientificNotation(stringValue, shiftExponent);
}

enum Shift {
  Left = -1,
  Right = 1,
}

function scientificNotationToParts(value: number): Array<string> {
  const [ stringValue, exponent ] = value.toString().split('e');
  return [ stringValue, exponent ];
}

function exponentForPrecision(exponent: string, precision: number, shift: Shift): number {
  precision = shift * precision;
  return exponent ? (Number(exponent) + precision) : precision;
}

function toScientificNotation(value: string, exponent: number): number {
  return Number(`${value}e${exponent}`);
}

Have you tried loading the socket.io script not from a relative URL?

You're using:

<script src="socket.io/socket.io.js"></script>

And:

socket.connect('http://127.0.0.1:8080');

You should try:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

And:

socket.connect('http://localhost:8080');

Switch localhost:8080 with whatever fits your current setup.

Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).

my two cents on this function:

var result = [];
for (var len = array.length, i = 0; i < len; ++i) {
  var age = array[i].age;
  if (result.indexOf(age) > -1) continue;
  result.push(age);
}

You can see the result here (Method 8) http://jsperf.com/distinct-values-from-array/3

"top" is usually available on Solaris.

If not then revert to "vmstat" which is available on most UNIX system.

It should look something like this (from an AIX box)

vmstat

System configuration: lcpu=4 mem=12288MB ent=2.00

kthr    memory              page              faults              cpu
----- ----------- ------------------------ ------------ -----------------------
 r  b   avm   fre  re  pi  po  fr   sr  cy  in   sy  cs us sy id wa    pc    ec

the colums "avm" and "fre" tell you the total memory and free memery.

a "man vmstat" should get you the gory details.

You can also say:

cut -d\  -f 2

Note that there are two spaces after the backslash.

you could get a htmldocument by:

 System.Net.WebClient wc = new System.Net.WebClient();

 System.IO.Stream stream = wc.OpenRead(url);
 System.IO.StreamReader reader = new System.IO.StreamReader(stream);
 string s = reader.ReadToEnd();

 HtmlDocument doc = new HtmlDocument();
 doc.LoadHtml(s);

so you have getbiyid and getbyname ... but any further you'd better of with
HTML Agility Pack as suggested . f.e you can do: doc.DocumentNode.SelectNodes(xpathselector) or regex to parse the doc ..

btw: why not regex ? . its soo cool if you can use it right... but xpath is also very mighty ... so "choose your poison"

Here is my python cv2 implementation:

import cv2

img=cv2.imread("path_to_image.jpg")

# rotate ccw
out=cv2.transpose(img)
out=cv2.flip(out,flipCode=0)

# rotate cw
out=cv2.transpose(img)
out=cv2.flip(out,flipCode=1)

cv2.imwrite("rotated.jpg", out)

By using Gson,

1. Convert POJO object to Json

2. Convert Json to Map

       retMap = new Gson().fromJson(new Gson().toJson(object), 
               new TypeToken<HashMap<String, Object>>() {}.getType()
       );
   

public class FileUploadExample extends HttpServlet {
     protected void doPost(HttpServletRequest request, HttpServletResponse response)
                throws ServletException, IOException {
            boolean isMultipart = ServletFileUpload.isMultipartContent(request);

            if (isMultipart) {
                // Create a factory for disk-based file items
                FileItemFactory factory = new DiskFileItemFactory();

                // Create a new file upload handler
                ServletFileUpload upload = new ServletFileUpload(factory);

                try {
                    // Parse the request
                    List items = upload.parseRequest(request);
                    Iterator iterator = items.iterator();
                    while (iterator.hasNext()) {
                        FileItem item = (FileItem) iterator.next();
                        if (!item.isFormField()) {
                            String fileName = item.getName();    
                            String root = getServletContext().getRealPath("/");
                            File path = new File(root + "/uploads");
                            if (!path.exists()) {
                                boolean status = path.mkdirs();
                            }

                            File uploadedFile = new File(path + "/" + fileName);
                            System.out.println(uploadedFile.getAbsolutePath());
                            item.write(uploadedFile);
                        }
                    }
                } catch (FileUploadException e) {
                    e.printStackTrace();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }

}

You could also look at how Python writes Excel-compatible csv files.

I believe the default for Excel is to double-up for literal quote characters - that is, literal quotes " are written as "".

It looks like you did not mention Ultimate++ iDE. It is quite fast. It is not perfect as Visual Studio but it has several useful features such as function list, it shows which function you are in,searches, multiple releases, package system, a gui designer a faster container library. Code completion...

Just change your syntax ever so slightly:

CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
     ELSE '"DECLINED"'
END

If you don't put the field expression before the CASE statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.

You can use realpath() function.

resolved_file = realpath(file_path, NULL);
if (!resolved_keyfile) {
   /*File dosn't exists*/
   perror(keyfile);
   return -1;
}

When testing for directories remember that every directory contains two special files.

One is called '.' and the other '..'

. is the directory's own name while .. is the name of it's parent directory.

To avoid trailing backslash problems just test to see if the directory knows it's own name.

eg:

if not exist %temp%\buffer\. mkdir %temp%\buffer

That looks fine, unless you want to pass it as Model string

public class HomeController : Controller
{
    public ActionResult Index()
    {
        string model = "<HTML></HTML>";
        return View(model);
    }
}

@model string
@{
    ViewBag.Title = "Index";
}

@Html.Raw(Model)

simple way to do maxlength for textarea in html4 is:

<textarea cols="60" rows="5" onkeypress="if (this.value.length > 100) { return false; }"></textarea>

Change the "100" to however many characters you want

Given that Windows has no sys/socket.h, you might consider just doing something like this:

#ifdef __WIN32__
# include <winsock2.h>
#else
# include <sys/socket.h>
#endif

I know you indicated that you won't use WinSock, but since WinSock is how TCP networking is done under Windows, I don't see that you have any alternative. Even if you use a cross-platform networking library, that library will be calling WinSock internally. Most of the standard BSD sockets API calls are implemented in WinSock, so with a bit of futzing around, you can make the same sockets-based program compile under both Windows and other OS's. Just don't forget to do a

#ifdef __WIN32__
   WORD versionWanted = MAKEWORD(1, 1);
   WSADATA wsaData;
   WSAStartup(versionWanted, &wsaData);
#endif

at the top of main()... otherwise all of your socket calls will fail under Windows, because the WSA subsystem wasn't initialized for your process.

Open up your file using regular old vanilla Notepad that comes with Windows.
It will show you the encoding of the file when you click "Save As...".
It'll look like this:

Whatever the default-selected encoding is, that is what your current encoding is for the file.
If it is UTF-8, you can change it to ANSI and click save to change the encoding (or visa-versa).

I realize there are many different types of encoding, but this was all I needed when I was informed our export files were in UTF-8 and they required ANSI. It was a onetime export, so Notepad fit the bill for me.

FYI: From my understanding I think "Unicode" (as listed in Notepad) is a misnomer for UTF-16.
More here on Notepad's "Unicode" option: Windows 7 - UTF-8 and Unicdoe

You have included a dependency on the SLF4J API, which is what you use in your application for logging, but you must also include an implementation that does the real logging work.

For example to log through Log4J you would add this dependency:

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.5.2</version>
    </dependency>

The recommended implementation would be logback-classic, which is the successor of Log4j, made by the same guys that made SLF4J and Log4J:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>0.9.24</version>
</dependency>

Note: The versions may be incorrect.

Time Zone

To format an Instant a time-zone is required. Without a time-zone, the formatter does not know how to convert the instant to human date-time fields, and therefore throws an exception.

The time-zone can be added directly to the formatter using withZone().

DateTimeFormatter formatter =
    DateTimeFormatter.ofLocalizedDateTime( FormatStyle.SHORT )
                     .withLocale( Locale.UK )
                     .withZone( ZoneId.systemDefault() );

If you specifically want an ISO-8601 format with no explicit time-zone (as the OP asked), with the time-zone implicitly UTC, you need

DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.from(ZoneOffset.UTC))

Generating String

Now use that formatter to generate the String representation of your Instant.

Instant instant = Instant.now();
String output = formatter.format( instant );

Dump to console.

System.out.println("formatter: " + formatter + " with zone: " + formatter.getZone() + " and Locale: " + formatter.getLocale() );
System.out.println("instant: " + instant );
System.out.println("output: " + output );

When run.

formatter: Localized(SHORT,SHORT) with zone: US/Pacific and Locale: en_GB
instant: 2015-06-02T21:34:33.616Z
output: 02/06/15 14:34

If you want to add the id manually you can use,

PadLeft() or String.Format() method.

string id;
char x='0';
id=id.PadLeft(6, x);
//Six character string id with left 0s e.g 000012

int id;
id=String.Format("{0:000000}",id);
//Integer length of 6 with the id. e.g 000012

Then you can append this with UID.

I would prefer to make a function that doesn't work with strings:

'---------------------------------------------------------------------------------------
' Procedure : RemoveTimeFromDate
' Author    : berend.nieuwhof
' Date      : 15-8-2013
' Purpose   : removes the time part of a String and returns the date as a date
'---------------------------------------------------------------------------------------
'
Public Function RemoveTimeFromDate(DateTime As Date) As Date


    Dim dblNumber As Double

    RemoveTimeFromDate = CDate(Floor(CDbl(DateTime)))

End Function

Private Function Floor(ByVal x As Double, Optional ByVal Factor As Double = 1) As Double
    Floor = Int(x / Factor) * Factor
End Function

Its very simple, 1)Just go on directory where the file us stored 2)then enter command i.e. type filename.file_extention e.g type MyFile.tx

i also had this issue- very annoying and haven't found a satisfactory sql answer myself yet (aside from long-winded ones involving creating temp tables etc.) and i didn't have time to explore it to the conclusion i'd have liked.

In the end just used SQL Server Management Studio to do it by selecting the table, right-clicking on the column and hitting rename. simples!

obviously i'd rather know how to do it without a gui but sometimes you've just gotta get sh** done!

To stage an entire folder, you'd enter this command:

    $git add .

The period will add all files in the folder.

For a line-by-line delta measurement, try gnonom.

It is a command line utility, a bit like moreutils's ts, to prepend timestamp information to the standard output of another command. Useful for long-running processes where you'd like a historical record of what's taking so long.

Piping anything to gnomon will prepend a timestamp to each line, indicating how long that line was the last line in the buffer--that is, how long it took the next line to appear. By default, gnomon will display the seconds elapsed between each line, but that is configurable.

I found this answer on another forum, works perfect. No problems with finding 1 if there is also a 10

WHERE tablename REGEXP "(^|,)@search(,|$)"

I found it here

select * from left table where key field not in (select key field from right table)

As far as I know, there is no way to get the ORM to issue bulk inserts. I believe the underlying reason is that SQLAlchemy needs to keep track of each object's identity (i.e., new primary keys), and bulk inserts interfere with that. For example, assuming your foo table contains an id column and is mapped to a Foo class:

x = Foo(bar=1)
print x.id
# None
session.add(x)
session.flush()
# BEGIN
# INSERT INTO foo (bar) VALUES(1)
# COMMIT
print x.id
# 1

Since SQLAlchemy picked up the value for x.id without issuing another query, we can infer that it got the value directly from the INSERT statement. If you don't need subsequent access to the created objects via the same instances, you can skip the ORM layer for your insert:

Foo.__table__.insert().execute([{'bar': 1}, {'bar': 2}, {'bar': 3}])
# INSERT INTO foo (bar) VALUES ((1,), (2,), (3,))

SQLAlchemy can't match these new rows with any existing objects, so you'll have to query them anew for any subsequent operations.

As far as stale data is concerned, it's helpful to remember that the session has no built-in way to know when the database is changed outside of the session. In order to access externally modified data through existing instances, the instances must be marked as expired. This happens by default on session.commit(), but can be done manually by calling session.expire_all() or session.expire(instance). An example (SQL omitted):

x = Foo(bar=1)
session.add(x)
session.commit()
print x.bar
# 1
foo.update().execute(bar=42)
print x.bar
# 1
session.expire(x)
print x.bar
# 42

session.commit() expires x, so the first print statement implicitly opens a new transaction and re-queries x's attributes. If you comment out the first print statement, you'll notice that the second one now picks up the correct value, because the new query isn't emitted until after the update.

This makes sense from the point of view of transactional isolation - you should only pick up external modifications between transactions. If this is causing you trouble, I'd suggest clarifying or re-thinking your application's transaction boundaries instead of immediately reaching for session.expire_all().

Have you tried following the advice on the linked help page? The help page at http://g.co/mapsJSApiErrors says:

ApiNotActivatedMapError

The Google Maps JavaScript API is not activated on your API project. You may need to enable the Google Maps JavaScript API under APIs in the Google Developers Console.

See Obtaining an API key.

So check that the key you are using has Google Maps JavaScript API enabled.

Better answer will be

git config push.default current

upsteam works but when you have no branch on origin then you will need to set the upstream branch. Changing it to current will automatically set the upsteam branch and will push the branch immediately.

Building off of Viktar's answer, here's an implementation you can call once on a given hidden input element to ensure that subsequent change events get fired whenever the value of the input element changes:

/**
 * Modifies the provided hidden input so value changes to trigger events.
 *
 * After this method is called, any changes to the 'value' property of the
 * specified input will trigger a 'change' event, just like would happen
 * if the input was a text field.
 *
 * As explained in the following SO post, hidden inputs don't normally
 * trigger on-change events because the 'blur' event is responsible for
 * triggering a change event, and hidden inputs aren't focusable by virtue
 * of being hidden elements:
 * https://stackoverflow.com/a/17695525/4342230
 *
 * @param {HTMLInputElement} inputElement
 *   The DOM element for the hidden input element.
 */
function setupHiddenInputChangeListener(inputElement) {
  const propertyName = 'value';

  const {get: originalGetter, set: originalSetter} =
    findPropertyDescriptor(inputElement, propertyName);

  // We wrap this in a function factory to bind the getter and setter values
  // so later callbacks refer to the correct object, in case we use this
  // method on more than one hidden input element.
  const newPropertyDescriptor = ((_originalGetter, _originalSetter) => {
    return {
      set: function(value) {
        const currentValue = originalGetter.call(inputElement);

        // Delegate the call to the original property setter
        _originalSetter.call(inputElement, value);

        // Only fire change if the value actually changed.
        if (currentValue !== value) {
          inputElement.dispatchEvent(new Event('change'));
        }
      },

      get: function() {
        // Delegate the call to the original property getter
        return _originalGetter.call(inputElement);
      }
    }
  })(originalGetter, originalSetter);

  Object.defineProperty(inputElement, propertyName, newPropertyDescriptor);
};

Call this on document ready like so:

$(document).ready(function() {
  setupHiddenInputChangeListener($('myinput')[0]);
});

This is actually javascript but related/relevant because .querySelectorAll targets by CSS syntax:

var i_will_target_self = document.querySelectorAll("ul.menu li a#example")

this example uses css to target links in a menu with id = "example"

that creates a variable which is a collection of the elements we want to change, but we still have actually change them by setting the new target ("_blank"):

for (var i = 0; i < 5; i++) {
i_will_target_self[i].target = "_blank";
}

That code assumes that there are 5 or less elements. That can be changed easily by changing the phrase "i < 5."

or if you develop on localhost (only for apache 2.4+):

<If "%{REMOTE_ADDR} != '127.0.0.1'">

Now there is a Native support in SQL Server (CTP3) for import, export, query and validate JSON inside T-SQL Refer to https://msdn.microsoft.com/en-us/library/dn921897.aspx

Please try to use this code for converting 3 decimal values after a point into 2 decimal places:

declare @val decimal (8, 2)
select @val = 123.456
select @val =  @val

select @val

The output is 123.46

If the server's certificate is self-signed, then this is working as designed and you will have to import the server's certificate into your keystore.

Assuming the server certificate is signed by a well-known CA, this is happening because the set of CA certificates available to a modern browser is much larger than the limited set that is shipped with the JDK/JRE.

The EasySSL solution given in one of the posts you mention just buries the error, and you won't know if the server has a valid certificate.

You must import the proper Root CA into your keystore to validate the certificate. There's a reason you can't get around this with the stock SSL code, and that's to prevent you from writing programs that behave as if they are secure but are not.

You can use the IsNullOrEmpty static method:

[string]::IsNullOrEmpty(...)

I'm using Eclipse Kepler release. There is no Installation Details or About Eclipse menu item under help. For me, it was Help | Eclipse Marketplace...

I had to click on the "Installed" tab. The plug-in I wanted to remove was listed there, with an "Uninstall" option.

You can compare class tokens to each other, so you could use value.getClass() == Integer.class. However, the simpler and more canonical way is to use instanceof :

    if (value instanceof Integer) {
        System.out.println("This is an Integer");
    } else if(value instanceof String) {
        System.out.println("This is a String");
    } else if(value instanceof Float) {
        System.out.println("This is a Float");
    }

Notes:

• the only difference between the two is that comparing class tokens detects exact matches only, while instanceof C matches for subclasses of C too. However, in this case all the classes listed are final, so they have no subclasses. Thus instanceof is probably fine here.

• as JB Nizet stated, such checks are not OO design. You may be able to solve this problem in a more OO way, e.g.

  System.out.println("This is a(n) " + value.getClass().getSimpleName());
  

complete executes after either the success or error callback were executed.

Maybe you should check the second parameter complete offers too. It's a String holding the type of success the ajaxCall had.

The different callbacks are described a little more in detail here jQuery.ajax( options )

I guess you missed the fact that the complete and the success function (I know inconsistent API) get different data passed in. success gets only the data, complete gets the whole XMLHttpRequest object. Of course there is no responseText property on the data string.

So if you replace complete with success you also have to replace data.responseText with data only.

success

The function gets passed two arguments: The data returned from the server, formatted according to the 'dataType' parameter, and a string describing the status.

complete

The function gets passed two arguments: The XMLHttpRequest object and a string describing the type of success of the request.

If you need to have access to the whole XMLHttpRequest object in the success callback I suggest trying this.

var myXHR = $.ajax({
    ...
    success: function(data, status) {
        ...do whatever with myXHR; e.g. myXHR.responseText...
    },
    ...
});

A Ternary is not a good solution for what you want. It will not be readable in your code, and there are much better solutions available.

Why not use an array lookup "map" or "dictionary", like so:

$vocations = array(
    1 => "Sorcerer",
    2 => "Druid",
    3 => "Paladin",
    ...
);

echo $vocations[$result->vocation];

A ternary for this application would end up looking like this:

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Why is this bad? Because - as a single long line, you would get no valid debugging information if something were to go wrong here, the length makes it difficult to read, plus the nesting of the multiple ternaries just feels odd.

A Standard Ternary is simple, easy to read, and would look like this:

$value = ($condition) ? 'Truthy Value' : 'Falsey Value';

or

echo ($some_condition) ? 'The condition is true!' : 'The condition is false.';

A ternary is really just a convenient / shorter way to write a simple if else statement. The above sample ternary is the same as:

if ($some_condition) {
    echo 'The condition is true!';
} else {
    echo 'The condition is false!';
}

However, a ternary for a complex logic quickly becomes unreadable, and is no longer worth the brevity.

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Even with some attentive formatting to spread it over multiple lines, it's not very clear:

echo($result->group_id == 1 
    ? "Player" 
    : ($result->group_id == 2 
        ? "Gamemaster" 
        : ($result->group_id == 3 
            ? "God" 
            : "unknown")));

In my case, the folder ProgramData was hidden by default on windows 7, so I was unable to find my.ini file.

After selecting show hidden files and folders option, I was able to find the my.ini file at the location: C:\ProgramData\MySQL\MySQL Server 5.6.

Display hidden files and folders on windows 7:

1. Right-click the Windows Logo button and choose Open Windows Explorer.

2. Click Organize and choose Folder and Search Options.

3. Click the View tab, select Show hidden files and folders and then clear the checkbox for Hide protected system operating files.

4. Click Yes on the warning and then click OK.

You can also use JFormattedTextField, which is much simpler to use. Example:

public static void main(String[] args) {
    NumberFormat format = NumberFormat.getInstance();
    NumberFormatter formatter = new NumberFormatter(format);
    formatter.setValueClass(Integer.class);
    formatter.setMinimum(0);
    formatter.setMaximum(Integer.MAX_VALUE);
    formatter.setAllowsInvalid(false);
    // If you want the value to be committed on each keystroke instead of focus lost
    formatter.setCommitsOnValidEdit(true);
    JFormattedTextField field = new JFormattedTextField(formatter);

    JOptionPane.showMessageDialog(null, field);

    // getValue() always returns something valid
    System.out.println(field.getValue());
}

I came up with an generic, interesting solution to this problem:

class SafeInvocator(object):
    def __init__(self, module):
        self._module = module

    def _safe(self, func):
        def inner(*args, **kwargs):
            try:
                return func(*args, **kwargs)
            except:
                return None

        return inner

    def __getattr__(self, item):
        obj = getattr(self.module, item)
        return self._safe(obj) if hasattr(obj, '__call__') else obj

and you can use it like so:

safe_json = SafeInvocator(json)
text = "{'foo':'bar'}"
item = safe_json.loads(text)
if item:
    # do something

If your repository enables setting revision properties via the pre-revprop-change hook you can change log messages much easier.

svn propedit --revprop -r 1234 svn:log url://to/repository

Or in TortoiseSVN, AnkhSVN and probably many other subversion clients by right clicking on a log entry and then 'change log message'.

Maybe silly, but check that you inline script is AFTER you include the script tags.

Like stated in this question: Git: Create a branch from unstagged/uncommited changes on master: stash is not necessary.

Just use:

git checkout -b topic/newbranch

Any uncommitted work will be taken along to the new branch.

If you try to push you will get the following message

fatal: The current branch feature/NEWBRANCH has no upstream branch. To push the current branch and set the remote as upstream, use

git push --set-upstream origin feature/feature/NEWBRANCH

Just do as suggested to create the branch remotely:

git push --set-upstream origin feature/feature/NEWBRANCH

There are 3 authentication protocols that can be used to perform authentication between Java and Active Directory on Linux or any other platform (and these are not just specific to HTTP services):

1. Kerberos - Kerberos provides Single Sign-On (SSO) and delegation but web servers also need SPNEGO support to accept SSO through IE.

2. NTLM - NTLM supports SSO through IE (and other browsers if they are properly configured).

3. LDAP - An LDAP bind can be used to simply validate an account name and password.

There's also something called "ADFS" which provides SSO for websites using SAML that calls into the Windows SSP so in practice it's basically a roundabout way of using one of the other above protocols.

Each protocol has it's advantages but as a rule of thumb, for maximum compatibility you should generally try to "do as Windows does". So what does Windows do?

First, authentication between two Windows machines favors Kerberos because servers do not need to communicate with the DC and clients can cache Kerberos tickets which reduces load on the DCs (and because Kerberos supports delegation).

But if the authenticating parties do not both have domain accounts or if the client cannot communicate with the DC, NTLM is required. So Kerberos and NTLM are not mutually exclusive and NTLM is not obsoleted by Kerberos. In fact in some ways NTLM is better than Kerberos. Note that when mentioning Kerberos and NTLM in the same breath I have to also mention SPENGO and Integrated Windows Authentication (IWA). IWA is a simple term that basically means Kerberos or NTLM or SPNEGO to negotiate Kerberos or NTLM.

Using an LDAP bind as a way to validate credentials is not efficient and requires SSL. But until recently implementing Kerberos and NTLM have been difficult so using LDAP as a make-shift authentication service has persisted. But at this point it should generally be avoided. LDAP is a directory of information and not an authentication service. Use it for it's intended purpose.

So how do you implement Kerberos or NTLM in Java and in the context of web applications in particular?

There are a number of big companies like Quest Software and Centrify that have solutions that specifically mention Java. I can't really comment on these as they are company-wide "identity management solutions" so, from looking the marketing spin on their website, it's hard to tell exactly what protocols are being used and how. You would need to contact them for the details.

Implementing Kerberos in Java is not terribly hard as the standard Java libraries support Kerberos through the org.ietf.gssapi classes. However, until recently there's been a major hurdle - IE doesn't send raw Kerberos tokens, it sends SPNEGO tokens. But with Java 6, SPNEGO has been implemented. In theory you should be able to write some GSSAPI code that can authenticate IE clients. But I haven't tried it. The Sun implementation of Kerberos has been a comedy of errors over the years so based on Sun's track record in this area I wouldn't make any promises about their SPENGO implementation until you have that bird in hand.

For NTLM, there is a Free OSS project called JCIFS that has an NTLM HTTP authentication Servlet Filter. However it uses a man-in-the-middle method to validate the credentials with an SMB server that does not work with NTLMv2 (which is slowly becoming a required domain security policy). For that reason and others, the HTTP Filter part of JCIFS is scheduled to be removed. Note that there are number of spin-offs that use JCIFS to implement the same technique. So if you see other projects that claim to support NTLM SSO, check the fine print.

The only correct way to validate NTLM credentials with Active Directory is using the NetrLogonSamLogon DCERPC call over NETLOGON with Secure Channel. Does such a thing exist in Java? Yes. Here it is:

http://www.ioplex.com/jespa.html

Jespa is a 100% Java NTLM implementation that supports NTLMv2, NTLMv1, full integrity and confidentiality options and the aforementioned NETLOGON credential validation. And it includes an HTTP SSO Filter, a JAAS LoginModule, HTTP client, SASL client and server (with JNDI binding), generic "security provider" for creating custom NTLM services and more.

To answer your question:

.html() will just call .innerHTML after doing some checks for nodeTypes and stuff. It also uses a try/catch block where it tries to use innerHTML first and if that fails, it'll fallback gracefully to jQuery's .empty() + append()

The only solution that worked for me: http://docs.moodle.org/23/en/Converting_your_MySQL_database_to_UTF8

Converting a database containing tables

mysqldump -uusername -ppassword -c -e --default-character-set=utf8 --single-transaction --skip-set-charset --add-drop-database -B dbname > dump.sql

cp dump.sql dump-fixed.sql
vim dump-fixed.sql

:%s/DEFAULT CHARACTER SET latin1/DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci/
:%s/DEFAULT CHARSET=latin1/DEFAULT CHARSET=utf8/
:wq

mysql -uusername -ppassword < dump-fixed.sql

I'm pretty sure it's an Adobe standard, bearing in mind the whole PDF standard is theirs to begin with; despite being open now.

My guess would be no for all PDF viewers supporting it, as some definitely will not have a JS engine. I doubt you can rely on full support outside the most recent versions of Acrobat (Reader). So I guess it depends on how you imagine it being used, if mainly via a browser display, then the majority of the market is catered for by Acrobat (Reader) and Chrome's built-in viewer - dare say there is documentation on whether Chrome's PDF viewer supports JS fully.

I hope this would be helpful:

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

I previously came up with a different workaround that doesn't use stored procedures, but instead uses a parameter table and some connection_id() magic.

EDIT (Copied up from comments)

create a table that contains a column called connection_id (make it a bigint). Place columns in that table for parameters for the view. Put a primary key on the connection_id. replace into the parameter table and use CONNECTION_ID() to populate the connection_id value. In the view use a cross join to the parameter table and put WHERE param_table.connection_id = CONNECTION_ID(). This will cross join with only one row from the parameter table which is what you want. You can then use the other columns in the where clause for example where orders.order_id = param_table.order_id.

Here is a short tutorial:

Model:

namespace ImageUploadApp.Models
{
    using System;
    using System.Collections.Generic;

    public partial class Image
    {
        public int ID { get; set; }
        public string ImagePath { get; set; }
    }
}

View:

1. Create:

   @model ImageUploadApp.Models.Image
   @{
       ViewBag.Title = "Create";
   }
   <h2>Create</h2>
   @using (Html.BeginForm("Create", "Image", null, FormMethod.Post, 
                                 new { enctype = "multipart/form-data" })) {
       @Html.AntiForgeryToken()
       @Html.ValidationSummary(true)
       <fieldset>
           <legend>Image</legend>
           <div class="editor-label">
               @Html.LabelFor(model => model.ImagePath)
           </div>
           <div class="editor-field">
               <input id="ImagePath" title="Upload a product image" 
                                     type="file" name="file" />
           </div>
           <p><input type="submit" value="Create" /></p>
       </fieldset>
   }
   <div>
       @Html.ActionLink("Back to List", "Index")
   </div>
   @section Scripts {
       @Scripts.Render("~/bundles/jqueryval")
   }
   

2. Index (for display):

   @model IEnumerable<ImageUploadApp.Models.Image>
   
   @{
       ViewBag.Title = "Index";
   }
   
   <h2>Index</h2>
   
   <p>
       @Html.ActionLink("Create New", "Create")
   </p>
   <table>
       <tr>
           <th>
               @Html.DisplayNameFor(model => model.ImagePath)
           </th>
       </tr>
   
   @foreach (var item in Model) {
       <tr>
           <td>
               @Html.DisplayFor(modelItem => item.ImagePath)
           </td>
           <td>
               @Html.ActionLink("Edit", "Edit", new { id=item.ID }) |
               @Html.ActionLink("Details", "Details", new { id=item.ID }) |
               @Ajax.ActionLink("Delete", "Delete", new {id = item.ID} })
           </td>
       </tr>
   }
   
   </table>
   

3. Controller (Create)

   public ActionResult Create(Image img, HttpPostedFileBase file)
   {
       if (ModelState.IsValid)
       {
           if (file != null)
           {
               file.SaveAs(HttpContext.Server.MapPath("~/Images/") 
                                                     + file.FileName);
               img.ImagePath = file.FileName;
           }  
           db.Image.Add(img);
           db.SaveChanges();
           return RedirectToAction("Index");
       }
       return View(img);
   }
   

Hope this will help :)

" is the correct way, the third of your tests:

<option value="&quot;asd">test</option>

You can see this working below, or on jsFiddle.

alert($("option")[0].value);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select>_x000D_
  <option value="&quot;asd">Test</option>_x000D_
</select>

Alternatively, you can delimit the attribute value with single quotes:

<option value='"asd'>test</option>

As ant31 already pointed out you can use the synchronize module to this. By default, the module transfers files between the control machine and the current remote host (inventory_host), however that can be changed using the task's delegate_to parameter (it's important to note that this is a parameter of the task, not of the module).

You can place the task on either ServerA or ServerB, but you have to adjust the direction of the transfer accordingly (using the mode parameter of synchronize).

Placing the task on ServerB

- hosts: ServerB
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
      delegate_to: ServerA

This uses the default mode: push, so the file gets transferred from the delegate (ServerA) to the current remote (ServerB).

This might sound like strange, since the task has been placed on ServerB (via hosts: ServerB). However, one has to keep in mind that the task is actually executed on the delegated host, which in this case is ServerA. So pushing (from ServerA to ServerB) is indeed the correct direction. Also remember that we cannot simply choose not to delegate at all, since that would mean that the transfer happens between the control machine and ServerB.

Placing the task on ServerA

- hosts: ServerA
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
        mode: pull
      delegate_to: ServerB

This uses mode: pull to invert the transfer direction. Again, keep in mind that the task is actually executed on ServerB, so pulling is the right choice.

I'd like to point out few more solutions to transposing columns and rows in SQL.

The first one is - using CURSOR. Although the general consensus in the professional community is to stay away from SQL Server Cursors, there are still instances whereby the use of cursors is recommended. Anyway, Cursors present us with another option to transpose rows into columns.

• Vertical expansion

  Similar to the PIVOT, the cursor has the dynamic capability to append more rows as your dataset expands to include more policy numbers.

• Horizontal expansion

  Unlike the PIVOT, the cursor excels in this area as it is able to expand to include newly added document, without altering the script.

• Performance breakdown

  The major limitation of transposing rows into columns using CURSOR is a disadvantage that is linked to using cursors in general – they come at significant performance cost. This is because the Cursor generates a separate query for each FETCH NEXT operation.

Another solution of transposing rows into columns is by using XML.

The XML solution to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation.

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

• Vertical expansion

  Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

• Horizontal expansion

  Unlike the PIVOT, newly added documents can be displayed without altering the script.

• Performance breakdown

  In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

I needed to get the form data as some sort of object. I used this:

$('#preview_form').serializeArray().reduce((function(acc, val) {
  acc[val.name.replace('[', '_').replace(']', '')] = val.value;
  return acc;
}), {});

A broader answer to this question might consider the Lego brick approach often used in Occam, and offered to the Java community via JCSP. There is a very good presentation by Peter Welch on this idea.

This plug-and-play approach translates directly to Go, because Go uses the same Communicating Sequential Process fundamentals as does Occam.

So, when it comes to designing repetitive tasks, you can build your system as a dataflow network of simple components (as goroutines) that exchange events (i.e. messages or signals) via channels.

This approach is compositional: each group of small components can itself behave as a larger component, ad infinitum. This can be very powerful because complex concurrent systems are made from easy to understand bricks.

Footnote: in Welch's presentation, he uses the Occam syntax for channels, which is ! and ? and these directly correspond to ch<- and <-ch in Go.

There is some basic pattern matching available through using LIKE, where % matches any number and combination of characters, _ matches any one character, and [abc] could match a, b, or c... There is more info on the MSDN site.

1- add to your profil file".bash_profile" file

it is in "/home/your_user/" folder

vi .bash_profile

add:

export JENKINS_HOME=/apps/data/jenkins  
export PATH=$PATH:$JENKINS_HOME

==> it's the e jenkins workspace

2- If you use jetty : go to jenkins.xml file

and add :

<Arg>/apps/data/jenkins</Arg>

DOMDocument::loadHTML will treat your string as being in ISO-8859-1 unless you tell it otherwise. This results in UTF-8 strings being interpreted incorrectly.

If your string doesn't contain an XML encoding declaration, you can prepend one to cause the string to be treated as UTF-8:

$profile = '<p>???????????????????????9</p>';
$dom = new DOMDocument();
$dom->loadHTML('<?xml encoding="utf-8" ?>' . $profile);
echo $dom->saveHTML();

If you cannot know if the string will contain such a declaration already, there's a workaround in SmartDOMDocument which should help you:

$profile = '<p>???????????????????????9</p>';
$dom = new DOMDocument();
$dom->loadHTML(mb_convert_encoding($profile, 'HTML-ENTITIES', 'UTF-8'));
echo $dom->saveHTML();

This is not a great workaround, but since not all characters can be represented in ISO-8859-1 (like these katana), it's the safest alternative.

<c:if test="${companies.size() > 0}">

</c:if>

This syntax works only in EL 2.2 or newer (Servlet 3.0 / JSP 2.2 or newer). If you're facing a XML parsing error because you're using JSPX or Facelets instead of JSP, then use gt instead of >.

<c:if test="${companies.size() gt 0}">

</c:if>

If you're actually facing an EL parsing error, then you're probably using a too old EL version. You'll need JSTL fn:length() function then. From the documentation:

length( java.lang.Object) - Returns the number of items in a collection, or the number of characters in a string.

Put this at the top of JSP page to allow the fn namespace:

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

Or if you're using JSPX or Facelets:

<... xmlns:fn="http://java.sun.com/jsp/jstl/functions">

And use like this in your page:

<p>The length of the companies collection is: ${fn:length(companies)}</p>

So to test with length of a collection:

<c:if test="${fn:length(companies) gt 0}">

</c:if>

Alternatively, for this specific case you can also simply use the EL empty operator:

<c:if test="${not empty companies}">

</c:if>

Using parse_str().

$str = 'pg_id=2&parent_id=2&document&video';
parse_str($str, $arr);
print_r($arr);

This will work, and if you need where statement you can add it as parameter.

class GenericDAOWithJPA<T, ID extends Serializable> {

.......

public List<T> findAll() {
            return entityManager.createQuery("Select t from " + persistentClass.getSimpleName() + " t").getResultList();
    }
}

To add to kosoant's answer, if you are using Spring, rather than writing your own Servlet filter, you can use the class org.springframework.web.filter.CharacterEncodingFilter they provide, configuring it like the following in your web.xml:

 <filter>
    <filter-name>encoding-filter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
       <param-name>encoding</param-name>
       <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
       <param-name>forceEncoding</param-name>
       <param-value>FALSE</param-value>
    </init-param>
 </filter>
 <filter-mapping>
    <filter-name>encoding-filter</filter-name>
    <url-pattern>/*</url-pattern>
 </filter-mapping>

Monkey is right, according to the link given by monkey

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting

The proper JPA query format would be:

el.name IN :inclList

If you're using an older version of Hibernate as your provider you have to write:

el.name IN (:inclList)

but that is a bug (HHH-5126) (EDIT: which has been resolved by now).

Since you're using Spring Boot, I assume you'd prefer to rely on Spring's auto configuration where possible. To add additional custom configuration like your interceptors, just provide a configuration or bean of WebMvcConfigurerAdapter.

Here's an example of a config class:

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

  @Autowired 
  HandlerInterceptor yourInjectedInterceptor;

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(...)
    ...
    registry.addInterceptor(getYourInterceptor()); 
    registry.addInterceptor(yourInjectedInterceptor);
    // next two should be avoid -- tightly coupled and not very testable
    registry.addInterceptor(new YourInterceptor());
    registry.addInterceptor(new HandlerInterceptor() {
        ...
    });
  }
}

NOTE do not annotate this with @EnableWebMvc, if you want to keep Spring Boots auto configuration for mvc.

Here it is:

SELECT 
   OBJECT_NAME(f.parent_object_id) TableName,
   COL_NAME(fc.parent_object_id,fc.parent_column_id) ColName
FROM 
   sys.foreign_keys AS f
INNER JOIN 
   sys.foreign_key_columns AS fc 
      ON f.OBJECT_ID = fc.constraint_object_id
INNER JOIN 
   sys.tables t 
      ON t.OBJECT_ID = fc.referenced_object_id
WHERE 
   OBJECT_NAME (f.referenced_object_id) = 'YourTableName'

This way, you'll get the referencing table and column name.

Edited to use sys.tables instead of generic sys.objects as per comment suggestion. Thanks, marc_s

I had the same problem. The bar had the same background color. Try:

android:scrollbarThumbVertical="@android:color/black"

Sorry Guys. I have solved this Issue long ago. I did a lot of changes. So I can't figure out which one does the trick.

1. I have changed the id as suggested by Jared Burrows.

2. Removed my support library and cleaned my project and Re added it.

3. Go to File -> Invalidate Caches/Restart.

Hope it works.

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.

I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:

seq 1 500000 | while read digit; do
    touch $(printf "abigfilename%06d\n" $digit);
done

And we note:

$ getconf ARG_MAX
2097152

Note however I can do this:

$ echo * > /dev/null

But this fails:

$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long

I can run a for loop:

$ for f in *; do :; done

which is another shell builtin.

Careful reading of the documentation for ARG_MAX states, Maximum length of argument to the exec functions. This means: Without calling exec, there is no ARG_MAX limitation. So it would explain why shell builtins are not restricted by ARG_MAX.

And indeed, I can ls my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX is working as advertised: the exec is failing with more than ARG_MAX characters on the argument list- including, it should be noted, the environment data.

On CentOS 7, try running following command:

sudo yum install php72u-gd.x86_64

Check if any of your .php files which printing some text, also is correctly encoding in utf-8.

If you are still not getting device token, try putting following code so to register your device for push notification.

It will also work on ios8 or more.

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000

    if ([UIApplication respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound
                                                                                 categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeAlert |
         UIRemoteNotificationTypeSound];

    }
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:

Give 0777 to all files and directories starting from the current path :

This is a quite old question, still comments show, that still people have problems, so here is my solution with following additional features:

• adjust the animation (speed, type, ...)
• does not need to extend any class
• in my case, animateLayoutChanges has problems in the new CoordinatorLayout

Function - Example (I have this function in an utility class)

public static void animateViewVisibility(final View view, final int visibility)
{
    // cancel runnning animations and remove and listeners
    view.animate().cancel();
    view.animate().setListener(null);

    // animate making view visible
    if (visibility == View.VISIBLE)
    {
        view.animate().alpha(1f).start();
        view.setVisibility(View.VISIBLE);
    }
    // animate making view hidden (HIDDEN or INVISIBLE)
    else
    {
        view.animate().setListener(new AnimatorListenerAdapter()
        {
            @Override
            public void onAnimationEnd(Animator animation)
            {
                view.setVisibility(visibility);
            }
        }).alpha(0f).start();
    }
}

Adjust animation

After calling view.animate() you can adjust the animation to whatever you want (set duration, set interpolator and more...). You may as well hide a view by scaling it instead of adjusting it's alpha value, just replace the alpha(...) with scaleX(...) or scaleY(...) in the utility method if you want that

++x is called preincrement while x++ is called postincrement.

int x = 5, y = 5;

System.out.println(++x); // outputs 6
System.out.println(x); // outputs 6

System.out.println(y++); // outputs 5
System.out.println(y); // outputs 6

You can make use of in_array() in PHP.

$os = array("uk", "us"); // You can set multiple check conditions here
if (in_array("uk", $os)) //Founds a match !
{
    echo "Got you"; 
}

Since the behavior is kind of strange, I have done some testing on the behavior, and here's my result:

TL;DR

If you are:

• In a form, and
• uses onclick="xxx()" on an element
• don't add id="xxx" or name="xxx" to that element
  • (e.g. <form><button id="totalbandwidth" onclick="totalbandwidth()">BAD</button></form> )

Here's are some test and their result:

Control sample (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button onclick="totalbandwidth()">SUCCESS</button>
</form>

Add id to button (failed to call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button id="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>

Add name to button (failed to call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button name="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>

Add value to button (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <input type="button" value="totalbandwidth" onclick="totalbandwidth()" />SUCCESS
</form>

Add id to button, but not in a form (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<button id="totalbandwidth" onclick="totalbandwidth()">SUCCESS</button>

Add id to another element inside the form (can successfully call function)

function totalbandwidth(){ alert("The answer is no, the span will not affect button"); }

<form onsubmit="return false;">
<span name="totalbandwidth" >Will this span affect button? </span>
<button onclick="totalbandwidth()">SUCCESS</button>
</form>

Using fetch for example like below:

 fetch(<"yoururl">, {
    method: 'GET',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + <your access token if need>
    },
       })
.then((response) => response.blob())
.then((blob) => {
// 2. Create blob link to download
 const url = window.URL.createObjectURL(new Blob([blob]));
const link = document.createElement('a');
link.href = url;
link.setAttribute('download', `sample.xlsx`);
 // 3. Append to html page
 document.body.appendChild(link);
 // 4. Force download
 link.click();
 // 5. Clean up and remove the link
 link.parentNode.removeChild(link);
})

You can paste in on Chrome console to test. the file with download with 'sample.xlsx' Hope it can help!

Thanks to @the-tin-man for putting together the benchmarks!

Alas, I don't really like any of those solutions. Either they require an extra step to get the result ([0] = '', .strip!) or they aren't very semantic/clear about what's happening ([1..-1]: "Um, a range from 1 to negative 1? Yearg?"), or they are slow or lengthy to write out (.gsub, .length).

What we are attempting is a 'shift' (in Array parlance), but returning the remaining characters, rather than what was shifted off. Let's use our Ruby to make this possible with strings! We can use the speedy bracket operation, but give it a good name, and take an arg to specify how much we want to chomp off the front:

class String
  def eat!(how_many = 1)
    self.replace self[how_many..-1]
  end
end

But there is more we can do with that speedy-but-unwieldy bracket operation. While we are at it, for completeness, let's write a #shift and #first for String (why should Array have all the fun??), taking an arg to specify how many characters we want to remove from the beginning:

class String
  def first(how_many = 1)
    self[0...how_many]
  end

  def shift(how_many = 1)
    shifted = first(how_many)
    self.replace self[how_many..-1]
    shifted
  end
  alias_method :shift!, :shift
end

Ok, now we have a good clear way of pulling characters off the front of a string, with a method that is consistent with Array#first and Array#shift (which really should be a bang method??). And we can easily get the modified string as well with #eat!. Hm, should we share our new eat!ing power with Array? Why not!

class Array
  def eat!(how_many = 1)
    self.replace self[how_many..-1]
  end
end

Now we can:

> str = "[12,23,987,43" #=> "[12,23,987,43"
> str.eat!              #=> "12,23,987,43"
> str                   #=> "12,23,987,43"

> str.eat!(3)           #=> "23,987,43"
> str                   #=> "23,987,43"

> str.first(2)          #=> "23"
> str                   #=> "23,987,43"

> str.shift!(3)         #=> "23,"
> str                   #=> "987,43"

> arr = [1,2,3,4,5]     #=> [1, 2, 3, 4, 5] 
> arr.eat!              #=> [2, 3, 4, 5] 
> arr                   #=> [2, 3, 4, 5] 

That's better!

Since you mentioned "within their browser" and firefox, if you are using Internet Explorer, you can disable the page header/footer by temporarily setting of the value in the registry, see here for an example. AFAIK I have not heard of a way to do this within other browsers. Both Daniel's and Mickel's answers seems to collide with each other, I guess that there could be a similar setting somewhere in the registry for firefox to remove headers/footers or customize them. Have you checked it out?

If the file was added with your most recent commit, and you have not pushed to the remote repository, you can delete the file and amend the commit, Taken from here:

git rm --cached giant_file
    # Stage "giant_file" for removal with "git rm"
    # Leave it on disk with "--cached". if you want to remove it from disk
    # then ignore the "--cached" parameter
git commit --amend -CHEAD
    # Commit the current tree without the giant file using "git commit"
    # Amend the previous commit with your change "--amend" 
    # (simply making a new commit won't work, as you need
    # to remove the file from the unpushed history as well)
    # Use the log/authorship/timestamp of the last commit (the one we are
    # amending) with "-CHEAD", equivalent to --reuse-message=HEAD
git push
    # Push our rewritten, smaller commit with "git push"

if(i <= 0 || i >=100)

It will work.

Given the range A:A, Id suggest:

=COUNTA(A:A)-(COUNTIF(A:A,"*")-COUNTIF(A:A,"?*"))

The problem is COUNTA over-counts by exactly the number of cells with zero length strings "".

The solution is to find a count of exactly these cells. This can be found by looking for all text cells and subtracting all text cells with at least one character

• COUNTA(A:A): cells with value, including "" but excluding truly empty cells
• COUNTIF(A:A,"*"): cells recognized as text, including "" but excluding truly blank cells
• COUNTIF(A:A,"?*"): cells recognized as text with at least one character

This means that the value COUNTIF(A:A,"*")-COUNTIF(A:A,"?*") should be the number of text cells minus the number of text cells that have at least one character i.e. the count of cells containing exactly ""

If you are using Mysql with Hibernate v3 it's ok to use GenerationType.AUTO because internally it will use GenerationType.IDENTITY, which is the most optimal in for MySQL.

However in Hibernate v5, It has changed. GenerationType.AUTO will use GenerationType.TABLE which generates to much queries for the insertion.

You can avoid that using GenerationType.IDENTITY (if MySQL is the only database you are using) or with these notations (if you have multiple databases):

@GeneratedValue(strategy = GenerationType.AUTO, generator = "native")
@GenericGenerator(name = "native", strategy = "native")
