If you can create a string xml you can easily transform it to the xml document object e.g. -

String xmlString = "<?xml version=\"1.0\" encoding=\"utf-8\"?><a><b></b><c></c></a>";  

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  
DocumentBuilder builder;  
try {  
    builder = factory.newDocumentBuilder();  
    Document document = builder.parse(new InputSource(new StringReader(xmlString)));  
} catch (Exception e) {  
    e.printStackTrace();  
} 

You can use the document object and xml parsing libraries or xpath to get back the ip address.

You can set the column index using index_col parameter available while reading from spreadsheet in Pandas.

Here is my solution:

1. Firstly, import pandas as pd: import pandas as pd

2. Read in filename using pd.read_excel() (if you have your data in a spreadsheet) and set the index to 'Locality' by specifying the index_col parameter.

   df = pd.read_excel('testexcel.xlsx', index_col=0)

   At this stage if you get a 'no module named xlrd' error, install it using pip install xlrd.

3. For visual inspection, read the dataframe using df.head() which will print the following output

4. Now you can fetch the values of the desired columns of the dataframe and print it

   

If someone is looking for a 93.9% solution. This works for me:

public static class StreamExtension
{
    /// <summary>
    /// Convert the content to a string.
    /// </summary>
    /// <param name="stream">The stream.</param>
    /// <returns></returns>
    public static string ReadAsString(this Stream stream)
    {
        var startPosition = stream.Position;
        try
        {
            // 1. Check for a BOM
            // 2. or try with UTF-8. The most (86.3%) used encoding. Visit: http://w3techs.com/technologies/overview/character_encoding/all/
            var streamReader = new StreamReader(stream, new UTF8Encoding(encoderShouldEmitUTF8Identifier: false, throwOnInvalidBytes: true), detectEncodingFromByteOrderMarks: true);
            return streamReader.ReadToEnd();
        }
        catch (DecoderFallbackException ex)
        {
            stream.Position = startPosition;

            // 3. The second most (6.7%) used encoding is ISO-8859-1. So use Windows-1252 (0.9%, also know as ANSI), which is a superset of ISO-8859-1.
            var streamReader = new StreamReader(stream, Encoding.GetEncoding(1252));
            return streamReader.ReadToEnd();
        }
    }
}

You can also set LD_RUN_PATH to /usr/local/lib in your user environment when you compile pycurl in the first place. This will embed /usr/local/lib in the RPATH attribute of the C extension module .so so that it automatically knows where to find the library at run time without having to have LD_LIBRARY_PATH set at run time.

To keep this simple, I just changed the directory from which I was importing the data to a local folder on the server.

I had the file located on a shared folder, I just copied my files to "c:\TEMP\Reports" on my server (updated the query to BULK INSERT from the new folder). The Agent task completed successfully :)

Finally after a long time I'm able to BULK Insert automatically via agent job.

Best regards.

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

           </executions>
         </plugin>
       </plugins>
     </build>
   </project>
   

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>
</dependency>

checker = None 

if some_decision:
    checker = True

if checker:
    # some stuff

[Edit]

For more information: http://docs.python.org/library/functions.html#bool

Your code works too, since 1 is converted to True when necessary. Actually Python didn't have a boolean type for a long time (as in old C), and some programmers still use integers instead of booleans.

In many cases some antivirus also start HyperV with window start and does not allow HAXM to install. I faced this issue because of AVAST antivirus. So I uninstalled AVAST, then HAXM installed properly after restart. Then I re-installed AVAST.

So its just a check while installing as now even with AVAST installed back, HAXM works properly with virtual box and android emulators.

DO it like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$yourPHPVAR%'");

Do not forget the % at the end

Maybe you'd like try run pip in Python shell like this:

>>> import pip
>>> pip.main(['install', 'requests'])

This will install requests package using pip.

Because pip is a module in standard library, but it isn't a built-in function(or module), so you need import it.

Other way, you should run pip in system shell(cmd. If pip is in path).

SQL Server

SELECT 
    c.name 
FROM
    sys.objects o
INNER JOIN
    sys.columns c
ON
    c.object_id = o.object_id
AND o.name = 'Table_Name'

or

SELECT 
    COLUMN_NAME 
FROM 
    INFORMATION_SCHEMA.COLUMNS
WHERE 
    TABLE_NAME  = 'Table_Name'

The second way is an ANSI standard and therefore should work on all ANSI compliant databases.

An instance variable would probably be the way to do what you want. You could make it static to persist the same value for the life of the program (or thread depending on your static memory model), or make it an ordinary instance var to control it over the life of an object instance. If that instance is a singleton, they'll behave the same way.

#if DEBUG
private /*static*/ bool s_bDoDebugOnlyCode = false;
#endif

void foo()
{   
  // ...
#if DEBUG
  if (s_bDoDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }
#endif
 // ...
}

Just to be complete, pragmas (preprocessor directives) are considered a bit of a kludge to use to control program flow. .NET has a built-in answer for half of this problem, using the "Conditional" attribute.

private /*static*/ bool doDebugOnlyCode = false; 
[Conditional("DEBUG")]
void foo()
{   
  // ...    
  if (doDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }    
  // ...
}

No pragmas, much cleaner. The downside is that Conditional can only be applied to methods, so you'll have to deal with a boolean variable that doesn't do anything in a release build. As the variable exists solely to be toggled from the VS execution host, and in a release build its value doesn't matter, it's pretty harmless.

Using ggplot and a little dplyr for data manipulation:

set.seed(42)
df <- data.frame(x = rep(1:10,each=5), y = rnorm(50))

library(ggplot2)
library(dplyr)

df.summary <- df %>% group_by(x) %>%
    summarize(ymin = min(y),
              ymax = max(y),
              ymean = mean(y))

ggplot(df.summary, aes(x = x, y = ymean)) +
    geom_point(size = 2) +
    geom_errorbar(aes(ymin = ymin, ymax = ymax))

If there's an additional grouping column (OP's example plot has two errorbars per x value, saying the data is sourced from two files), then you should get all the data in one data frame at the start, add the grouping variable to the dplyr::group_by call (e.g., group_by(x, file) if file is the name of the column) and add it as a "group" aesthetic in the ggplot, e.g., aes(x = x, y = ymean, group = file).

The docs are pretty clear that you pass in a second parameter to specify granularity.

If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.

moment('2010-10-20').isAfter('2010-01-01', 'year'); // false
moment('2010-10-20').isAfter('2009-12-31', 'year'); // true

As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day.

For your case you would pass 'day' as the second parameter.

Also you can try this, if you want to focus on same text after error.

If you wants to show this error message in a paragraph then you can use this one:

 $(document).ready(function () {
    $("#submit").click(function () {
        if($('#selBooks').val() === '') {
            $("#Paragraph_id").text("Please select a book and then proceed.").show();
            $('#selBooks').focus();
            return false;
        }
    });
 });

// read file and make object
let content = JSON.parse(fs.readFileSync('file.json', 'utf8'));
// edit or add property
content.expiry_date = 999999999999;
//write file
fs.writeFileSync('file.json', JSON.stringify(content));

After struggling with this issue for some time and researching about it, I finally managed to solve it following these steps:

1) install jdk version 12
2) Create new variable in systems variable
3) Name it as JAVA_HOME and give jdk installation path
4) add this variable in path and move it to top.
5) go to C:\Program Files (86)\Common Files\Oracle\Java\javapath and replace java.exe and javaw.exe with the corresponding files with the same names from the pathtojavajdk/bin folder

Finally, I checked the default version of java in cmd with "java -version" and it worked!

Detecting peaks in a spectrum in a reliable way has been studied quite a bit, for example all the work on sinusoidal modelling for music/audio signals in the 80ies. Look for "Sinusoidal Modeling" in the literature.

If your signals are as clean as the example, a simple "give me something with an amplitude higher than N neighbours" should work reasonably well. If you have noisy signals, a simple but effective way is to look at your peaks in time, to track them: you then detect spectral lines instead of spectral peaks. IOW, you compute the FFT on a sliding window of your signal, to get a set of spectrum in time (also called spectrogram). You then look at the evolution of the spectral peak in time (i.e. in consecutive windows).

Coinbase has a REST API that gives you access to historical prices from their website. The data seems to show the Coinbase spot price (in USD) about every ten minutes.

Results are returned in CSV format. You must query the page number you want through the API. There are 1000 results (or price points) per page. That's about 7 days' worth of data per page.

When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink], then it should be assigned a name of the property the value of which will be the route it should navigate the user to.

So to fix your issue, replace this routerLink="['/about']" with routerLink="/about" in your HTML.

There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:

<nav class="main-nav>
  <ul 
    class="main-nav__list" 
    ng-sticky 
    addClass="main-sticky-link" 
    [ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
    <li class="main-nav__item" routerLinkActive="active">
      <a class="main-nav__link" routerLink="/">Home</a>
    </li>
    <li class="main-nav__item" routerLinkActive="active"> 
      <a class="main-nav__link" routerLink="/about">About us</a>
    </li>
  </ul>
</nav>

It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>, either in your template provided above or in a parent component.

There's another issue with your AppRoutingModule. You need to export the RouterModule from there so that it is available to your AppModule when it imports it. To fix that, export it from your AppRoutingModule by adding it to the exports array.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
  { path: 'about', component: AboutComponent },
  { path: 'what', component: WhatwedoComponent },
  { path: 'contacts', component: FooterComponent },
  { path: 'projects', component: ProjectsComponent},
];

@NgModule({
  imports: [
    CommonModule,
    RouterModule.forRoot(routes),
  ],
  exports: [RouterModule],
  declarations: []
})
export class AppRoutingModule { }

If you want easy to use libraries, you can use the NUGET packages:

• ExcelDataReader - to read Excel files (most file formats)
• SwiftExcel - to write Excel files (.xlsx)

Note these are 3rd-Party packages - you can use them for basic functionality for free, but if you want more features there might be a "pro" version.

They are using a two-dimensional object array (i.e. object[][] cells) to read / write data.

java.time

In Java 8 and later it could be done in one line using class java.time.LocalTime.

In the formatting pattern, lowercase hh means 12-hour clock while uppercase HH means 24-hour clock.

Code example:

String result =                                       // Text representing the value of our date-time object.
    LocalTime.parse(                                  // Class representing a time-of-day value without a date and without a time zone.
        "03:30 PM" ,                                  // Your `String` input text.
        DateTimeFormatter.ofPattern(                  // Define a formatting pattern to match your input text.
            "hh:mm a" ,
            Locale.US                                 // `Locale` determines the human language and cultural norms used in localization. Needed here to translate the `AM` & `PM` value.
        )                                             // Returns a `DateTimeFormatter` object.
    )                                                 // Return a `LocalTime` object.
    .format( DateTimeFormatter.ofPattern("HH:mm") )   // Generate text in a specific format. Returns a `String` object.
;

I did the same thing that @Diode, the first answer, but i made the condition with a range of dates, i hope this example going to be useful for someone

e.g (the same code to example with array of dates)

var dateFrom = "02/06/2013";_x000D_
var dateTo = "02/09/2013";_x000D_
_x000D_
var d1 = dateFrom.split("/");_x000D_
var d2 = dateTo.split("/");_x000D_
_x000D_
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]);  // -1 because months are from 0 to 11_x000D_
var to   = new Date(d2[2], parseInt(d2[1])-1, d2[0]); _x000D_
_x000D_
_x000D_
_x000D_
var dates= ["02/06/2013", "02/07/2013", "02/08/2013", "02/09/2013", "02/07/2013", "02/10/2013", "02/011/2013"];_x000D_
_x000D_
dates.forEach(element => {_x000D_
   let parts = element.split("/");_x000D_
   let date= new Date(parts[2], parseInt(parts[1]) - 1, parts[0]);_x000D_
        if (date >= from && date < to) {_x000D_
           console.log('dates in range', date);_x000D_
        }_x000D_
})

As mentioned in Scott Kuhl's answer this issue is mentioned in https://github.com/madskristensen/WebCompiler/issues/413

For me, running the command npm i caniuse-lite- browserslist only worked for about 1/2 a day before it was an issue again.

The following solution, mentioned in the post, works much better. This updates the node.js file so that it uses console.log instead of console.warn when returning these errors.

You can manually update this file located at C:\Users\[Username]\AppData\Local\Temp\WebCompiler[VersionNumber]\node_modules\browserslist

Or, so that it is done automatically, add the following to your .csproj file by:

1. Right click on project file and select "Unload Project"
2. Edit the .csproj file
3. Paste the following into the project file. I pasted it towards the end of the file, before the </Project> end tag and before the build web compiler package was imported.

    <ItemGroup>
        <PackageReference Include="MSBuildTasks" Version="1.5.0.235">
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
        </PackageReference>
    </ItemGroup>
    <PropertyGroup>
        <TempFolder>$([System.IO.Path]::GetTempPath())</TempFolder>
    </PropertyGroup>
    <ItemGroup>
        <BrowsersListNodeJsFiles Include="$(TempFolder)\WebCompiler*\node_modules\browserslist\node.js" />
    </ItemGroup>
    <Target Name="BrowsersListWarningsAsInfo" BeforeTargets="WebCompile">
        <FileUpdate Files="@(BrowsersListNodeJsFiles)"
                    Regex="console.warn"
                    ReplacementText="console.log" />
    </Target>

4. Reload the project back into the solution.

You are trying access a non-static class in a static way. Change Builder to static class Builder and it should work.

The example usage you give fails because there is no instance of Builder present. A static class for all practical purposes is always instantiated. If you don't make it static, you'd need to say:

Widget = new Widget.Builder(10).setparm1(1).setparm2(3).build();

Because you would need to construct a new Builder every time.

My working example of using style and android:theme simultaneously (API >= 21)

<android.support.v7.widget.SwitchCompat
    android:id="@+id/wan_enable_nat_switch"
    style="@style/Switch"
    app:layout_constraintBaseline_toBaselineOf="@id/wan_enable_nat_label"
    app:layout_constraintEnd_toEndOf="parent" />

<style name="Switch">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:paddingEnd">16dp</item>
    <item name="android:focusableInTouchMode">true</item>
    <item name="android:theme">@style/ThemeOverlay.MySwitchCompat</item>
</style>

<style name="ThemeOverlay.MySwitchCompat" parent="">
    <item name="colorControlActivated">@color/colorPrimaryDark</item>
    <item name="colorSwitchThumbNormal">@color/text_outline_not_active</item>
    <item name="android:colorForeground">#42221f1f</item>
</style>

Just to add

Lynda.com has a fantastic DVD called

iPhone SDK Essential Training

and Chapter 6, Lesson 3 is all about EXEC_BAD_ACCESS and working with Zombies.

It was great for me to understand, not just the error code but how can I use Zombies to get more info on the released object.

You have to specify the name of the custom view and its related model in Controller Action method.

public ActionResult About()
{            
   return View("NameOfViewYouWantToReturn",Model); 
}

$('input[type=file]').val()

That'll get you the file selected.

However, you can't set the value yourself.

I solved this issue for me by checking that Maven Dependencies were being deployed in Deployment Assembly. In my case they were not.

Adding it fixed the problem.

These answers are outdated and depreciated. Best practice..

composer require phpmailer/phpmailer

The next on your sendmail.php file just require the following

# use namespace
use PHPMailer\PHPMailer\PHPMailer;

# require php mailer
require_once "../vendor/autoload.php";

//PHPMailer Object
$mail = new PHPMailer;

//From email address and name
$mail->From = "[email protected]";
$mail->FromName = "Full Name";

//To address and name
$mail->addAddress("[email protected]", "Recepient Name");
$mail->addAddress("[email protected]"); //Recipient name is optional

//Address to which recipient will reply
$mail->addReplyTo("[email protected]", "Reply");

//CC and BCC
$mail->addCC("[email protected]");
$mail->addBCC("[email protected]");

//Send HTML or Plain Text email
$mail->isHTML(true);

$mail->Subject = "Subject Text";
$mail->Body = "<i>Mail body in HTML</i>";
$mail->AltBody = "This is the plain text version of the email content";

if(!$mail->send()) 
{
    echo "Mailer Error: " . $mail->ErrorInfo;
} 
else 
{
    echo "Message has been sent successfully";
}

This can be configure how ever you like..

I have modified the above answer, so you don't need to cast from Object

public static <T> List<T> safeClient( List<T> other ) {
            return other == null ? Collections.EMPTY_LIST : other;
}

and then simply call the List by

for (MyOwnObject ownObject : safeClient(someList)) {
    // do whatever
}

Explaination: MyOwnObject: If List<Integer> then MyOwnObject will be Integer in this case.

For me it was trigger issue. By default it should On a Schedule in trigger tab. I had selected At log on and then I was waiting to run task. As it's name says at log on, means you have to logout and log on.

Try putting it on a Schedule and fire it every minute.

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

You can just say

callback();

Alternately you can use the call method if you want to adjust the value of this within the callback.

callback.call( newValueForThis);

Inside the function this would be whatever newValueForThis is.

The only library that I got to work for Chrome, Firefox and MS Edge was rasterizeHTML. It outputs better quality that HTML2Canvas and is still supported unlike HTML2Canvas.

Getting Element and Downloading as PNG

var node= document.getElementById("elementId");
var canvas = document.createElement("canvas");
canvas.height = node.offsetHeight;
canvas.width = node.offsetWidth;
var name = "test.png"

rasterizeHTML.drawHTML(node.outerHTML, canvas)
     .then(function (renderResult) {
            if (navigator.msSaveBlob) {
                window.navigator.msSaveBlob(canvas.msToBlob(), name);
            } else {
                const a = document.createElement("a");
                document.body.appendChild(a);
                a.style = "display: none";
                a.href = canvas.toDataURL();
                a.download = name;
                a.click();
                document.body.removeChild(a);
            }
     });

But this is usually not a nice way to align some content. You better put your different content in

Examples

Given the string foobarbarfoo:

bar(?=bar)     finds the 1st bar ("bar" which has "bar" after it)
bar(?!bar)     finds the 2nd bar ("bar" which does not have "bar" after it)
(?<=foo)bar    finds the 1st bar ("bar" which has "foo" before it)
(?<!foo)bar    finds the 2nd bar ("bar" which does not have "foo" before it)

You can also combine them:

(?<=foo)bar(?=bar)    finds the 1st bar ("bar" with "foo" before it and "bar" after it)

Definitions

Look ahead positive (?=)

Find expression A where expression B follows:

A(?=B)

Look ahead negative (?!)

Find expression A where expression B does not follow:

A(?!B)

Look behind positive (?<=)

Find expression A where expression B precedes:

(?<=B)A

Look behind negative (?<!)

Find expression A where expression B does not precede:

(?<!B)A

Atomic groups (?>)

An atomic group exits a group and throws away alternative patterns after the first matched pattern inside the group (backtracking is disabled).

• (?>foo|foot)s applied to foots will match its 1st alternative foo, then fail as s does not immediately follow, and stop as backtracking is disabled

A non-atomic group will allow backtracking; if subsequent matching ahead fails, it will backtrack and use alternative patterns until a match for the entire expression is found or all possibilities are exhausted.

• (foo|foot)s applied to foots will:

  1. match its 1st alternative foo, then fail as s does not immediately follow in foots, and backtrack to its 2nd alternative;
  2. match its 2nd alternative foot, then succeed as s immediately follows in foots, and stop.

you can do something for a list object,

data("mtcars")
rownames(mtcars)
data <- list(mtcars ,mtcars, mtcars, mtcars);data

out1 <- NULL 
for(i in seq_along(data)) { 
  out1[[i]] <- data[[i]][rownames(data[[i]]) != "Volvo 142E", ] } 
out1

Or a data frame,

data("mtcars")
df <- mtcars
out1 <- NULL 
for(i in 1:nrow(df)) {
  row <- rownames(df[i,])
  # do stuff with row
  out1 <- df[rownames(df) != "Volvo 142E",]
  
}

There's a I/O library available, but if it's available depends on your scripting host (assuming you've embedded lua somewhere). It's available, if you're using the command line version. The complete I/O model is most likely what you're looking for.

Updated for c# 6:

    try

    catch (SqlException ex) when (ex.Number == -2)  // -2 is a sql timeout
    {
        // handle timeout
    }

Very simple and nice to look at!!

npm has an official page about fixing npm permissions when you get the EACCES (Error: Access) error. The page even has a video.

You can fix this problem using one of two options:

1. Change the permission to npm's default directory.
2. Change npm's default directory to another directory.

The solution below has a "SEO friendlier" version:

function hyphenize($string) {

        "thier"    => "their",
        // Add your own replacements here
    );
    return strtolower(
        preg_replace(
          array( '#[\\s-]+#', '#[^A-Za-z0-9. -]+#' ),
          array( '-', '' ),
          // the full cleanString() can be downloaded from http://www.unexpectedit.com/php/php-clean-string-of-utf8-chars-convert-to-similar-ascii-char
          cleanString(
              str_replace( // preg_replace can be used to support more complicated replacements
                  array_keys($dict),
                  array_values($dict),
                  urldecode($string)
              )
          )
        )
    );
}

function cleanString($text) {
    $utf8 = array(
        '/[áàâãªä]/u'   =>   'a',
        '/[ÁÀÂÃÄ]/u'    =>   'A',
        '/[ÍÌÎÏ]/u'     =>   'I',
        '/[íìîï]/u'     =>   'i',
        '/[éèêë]/u'     =>   'e',
        '/[ÉÈÊË]/u'     =>   'E',
        '/[óòôõºö]/u'   =>   'o',
        '/[ÓÒÔÕÖ]/u'    =>   'O',
        '/[úùûü]/u'     =>   'u',
        '/[ÚÙÛÜ]/u'     =>   'U',
        '/ç/'           =>   'c',
        '/Ç/'           =>   'C',
        '/ñ/'           =>   'n',
        '/Ñ/'           =>   'N',
        '/–/'           =>   '-', // UTF-8 hyphen to "normal" hyphen
        '/[’‘‹›‚]/u'    =>   ' ', // Literally a single quote
        '/[“”«»„]/u'    =>   ' ', // Double quote
        '/ /'           =>   ' ', // nonbreaking space (equiv. to 0x160)
    );
    return preg_replace(array_keys($utf8), array_values($utf8), $text);
}

The rationale for the above functions (which I find way inefficient - the one below is better) is that a service that shall not be named apparently ran spelling checks and keyword recognition on the URLs.

After losing a long time on a customer's paranoias, I found out they were not imagining things after all -- their SEO experts [I am definitely not one] reported that, say, converting "Viaggi Economy Perù" to viaggi-economy-peru "behaved better" than viaggi-economy-per (the previous "cleaning" removed UTF8 characters; Bogotà became bogot, Medellìn became medelln and so on).

There were also some common misspellings that seemed to influence the results, and the only explanation that made sense to me is that our URL were being unpacked, the words singled out, and used to drive God knows what ranking algorithms. And those algorithms apparently had been fed with UTF8-cleaned strings, so that "Perù" became "Peru" instead of "Per". "Per" did not match and sort of took it in the neck.

In order to both keep UTF8 characters and replace some misspellings, the faster function below became the more accurate (?) function above. $dict needs to be hand tailored, of course.

Previous answer

A simple approach:

// Remove all characters except A-Z, a-z, 0-9, dots, hyphens and spaces
// Note that the hyphen must go last not to be confused with a range (A-Z)
// and the dot, NOT being special (I know. My life was a lie), is NOT escaped

$str = preg_replace('/[^A-Za-z0-9. -]/', '', $str);

// Replace sequences of spaces with hyphen
$str = preg_replace('/  */', '-', $str);

// The above means "a space, followed by a space repeated zero or more times"
// (should be equivalent to / +/)

// You may also want to try this alternative:
$str = preg_replace('/\\s+/', '-', $str);

// where \s+ means "zero or more whitespaces" (a space is not necessarily the
// same as a whitespace) just to be sure and include everything

Note that you might have to first urldecode() the URL, since %20 and + both are actually spaces - I mean, if you have "Never%20gonna%20give%20you%20up" you want it to become Never-gonna-give-you-up, not Never20gonna20give20you20up . You might not need it, but I thought I'd mention the possibility.

So the finished function along with test cases:

function hyphenize($string) {
    return 
    ## strtolower(
          preg_replace(
            array('#[\\s-]+#', '#[^A-Za-z0-9. -]+#'),
            array('-', ''),
        ##     cleanString(
              urldecode($string)
        ##     )
        )
    ## )
    ;
}

print implode("\n", array_map(
    function($s) {
            return $s . ' becomes ' . hyphenize($s);
    },
    array(
    'Never%20gonna%20give%20you%20up',
    "I'm not the man I was",
    "'Légeresse', dit sa majesté",
    )));


Never%20gonna%20give%20you%20up    becomes  never-gonna-give-you-up
I'm not the man I was              becomes  im-not-the-man-I-was
'Légeresse', dit sa majesté        becomes  legeresse-dit-sa-majeste

To handle UTF-8 I used a cleanString implementation found online (link broken since, but a stripped down copy with all the not-too-esoteric UTF8 characters is at the beginning of the answer; it's also easy to add more characters to it if you need) that converts UTF8 characters to normal characters, thus preserving the word "look" as much as possible. It could be simplified and wrapped inside the function here for performance.

The function above also implements converting to lowercase - but that's a taste. The code to do so has been commented out.

Echo inside an HTML element with class and style the element:

echo "<span class='name'>" . $ip['cityName'] . "</span>";

If you don't want/need to be tied to a concrete class, you can pass JSON directly to a WebAPI controller. The controller is able to accept the JSON by using the ExpandoObject type. Here is the method example:

public void Post([FromBody]ExpandoObject json)
{
    var keyValuePairs = ((System.Collections.Generic.IDictionary<string, object>)json);
}

Set the Content-Type header to application/json and send the JSON as the body. The keyValuePairs object will contain the JSON key/value pairs.

Or you can have the method accept the incoming JSON as a JObject type (from Newtonsoft JSON library), and by setting it to a dynamic type, you can access the properties by dot notation.

public void Post([FromBody]JObject _json)
{
    dynamic json = _json;
}

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

We can use generate function which exists in algorithm header file.

Code Snippet :

#include<bits/stdc++.h>
using namespace std;


int main()
{
    ios::sync_with_stdio(false);

    vector<int>v(10);

    int n=0;

    generate(v.begin(), v.end(), [&n] { return n++;});

    for(auto item : v)
    {
      cout<<item<<" ";
    }
    cout<<endl;

    return 0;
}

Have you just modularized any of your React components? If yes, you will get this error if you forgot to specify module.exports, for example:

non-modularized previously valid component/code:

var YourReactComponent = React.createClass({
    render: function() { ...

modularized component/code with module.exports:

module.exports = React.createClass({
    render: function() { ...

The customary method for doing this sort of thing is to "print to string". In C++ that means using std::stringstream something like:

std::stringstream ss;
ss << std::fixed << std::setprecision(2) << number;
std::string mystring = ss.str();

Just put in fg and go back to your most recently suspended program.

How about something like: Using HTML Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
foreach (HtmlNode table in doc.DocumentNode.SelectNodes("//table")) {
    Console.WriteLine("Found: " + table.Id);
    foreach (HtmlNode row in table.SelectNodes("tr")) {
        Console.WriteLine("row");
        foreach (HtmlNode cell in row.SelectNodes("th|td")) {
            Console.WriteLine("cell: " + cell.InnerText);
        }
    }
}

Note that you can make it prettier with LINQ-to-Objects if you want:

var query = from table in doc.DocumentNode.SelectNodes("//table").Cast<HtmlNode>()
            from row in table.SelectNodes("tr").Cast<HtmlNode>()
            from cell in row.SelectNodes("th|td").Cast<HtmlNode>()
            select new {Table = table.Id, CellText = cell.InnerText};

foreach(var cell in query) {
    Console.WriteLine("{0}: {1}", cell.Table, cell.CellText);
}

If you have Jackson integeration with your application to serialize your bean to JSON format, then you can use Jackson anotation @JsonFormat to format your date to specified format.
In your case if you need your date into yyyy-MM-dd format you need to specify @JsonFormat above your field on which you want to apply this format.

For Example :

public class Subject {

     private String uid;
     private String number;
     private String initials;

     @JsonFormat(pattern="yyyy-MM-dd")
     private Date dateOfBirth;  

     //Other Code  

}  

From Docs :

annotation used for configuring details of how values of properties are to be serialized.

See here for starting the service and here for how to make it permanent. In short to test it, open a "DOS" terminal with administrator privileges and write:

It can be due to a number of reasons happening when configuring the listener. Best way is to log and see the actual error. You can do this by adding a logging.properties file to the root of your classpath with the following contents:

the html element break line depend of it's white-space style property. in the most of the elements the default white-space is auto, which mean break line when the text come to the width of the element. if you want the text break by \n you have to give to the parent element the style: white space: pre-line, which will read the \n and break the line, or white-space: pre which will also read \t etc. note: to write \n as break-line and not as a string , you have to use a double quoted string ("\n") if you not wanna use a white space, you always welcome to use the HTML Element for break line, which is <br/>

You can use CSS grid to achieve this, this is the long-hand version for the purposes of illustration:

div.container {_x000D_
    display: grid;_x000D_
    grid-template-columns: 220px 20px auto;_x000D_
    grid-template-rows: auto;_x000D_
}_x000D_
_x000D_
div.left {_x000D_
    grid-column-start: 1;_x000D_
    grid-column-end: 2;_x000D_
    grid-row-start: row1-start_x000D_
    grid-row-end: 3;_x000D_
    background-color: Aqua;_x000D_
}_x000D_
_x000D_
div.right {_x000D_
    grid-column-start: 3;_x000D_
    grid-column-end: 4;_x000D_
    grid-row-start: 1;_x000D_
    grid-row-end; 1;_x000D_
    background-color: Silver;_x000D_
}_x000D_
_x000D_
div.below {_x000D_
    grid-column-start: 1;_x000D_
    grid-column-end: 4;_x000D_
    grid-row-start: 2;_x000D_
    grid-row-end; 2;_x000D_
}

<div class="container">_x000D_
    <div class="left">Left</div>_x000D_
    <div class="right">Right</div>_x000D_
    <div class="below">Below</div>_x000D_
</div>

Or the more traditional method using float and margin.

I have included a background colour in this example to help show where things are - and also what to do with content below the floated-area.

Don't put your styles inline in real life, extract them into a style sheet.

div.left {_x000D_
    width: 200px;_x000D_
    float: left;_x000D_
    background-color: Aqua;_x000D_
}_x000D_
_x000D_
div.right {_x000D_
    margin-left: 220px;_x000D_
    background-color: Silver;_x000D_
}_x000D_
_x000D_
div.clear {_x000D_
    clear: both;_x000D_
}

    <div class="left"> Left </div>_x000D_
    <div class="right"> Right </div>_x000D_
    <div class="clear">Below</div>

<div style="width: 200px; float: left; background-color: Aqua;"> Left </div>
<div style="margin-left: 220px; background-color: Silver;"> Right </div>
<div style="clear: both;">Below</div>

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"

The "input" function converts the input you enter as if it were python code. "raw_input" doesn't convert the input and takes the input as it is given. Its advisable to use raw_input for everything. Usage:

>>a = raw_input()
>>5
>>a
>>'5'

MSDN on:

• navigator.userLanguage

From browserLanguage:

In Microsoft Internet Explorer 4.0 and earlier, the browserLanguage property reflects the language of the installed browser's user interface. For example, if you install a Japanese version of Windows Internet Explorer on an English operating system, browserLanguage would be ja.

In Internet Explorer 5 and later, however, the browserLanguage property reflects the language of the operating system regardless of the installed language version of Internet Explorer. However, if Microsoft Windows 2000 MultiLanguage version is installed, the browserLanguage property indicates the language set in the operating system's current menus and dialogs, as found in the Regional Options of the Control Panel. For example, if you install a Japanese version of Internet Explorer 5 on an English (United Kingdom) operating system, browserLanguage would be en-gb. If you install Windows 2000 MultiLanguage version and set the language of the menus and dialogs to French, browserLanguage would be fr, even though you have a Japanese version of Internet Explorer.

Note This property does not indicate the language or languages set by the user in Language Preferences, located in the Internet Options dialog box.

Furthermore, it looks like browserLanguage is deprecated cause IE8 doesn't list it

yourString += "newString"

This way you can concatenate a string

I tried a few ones above but they seem to reset @ 1000

This one definately works, and should also take year into consideration

long millisStart = Calendar.getInstance().getTimeInMillis();

and then do the same for end time if needed.

Here is an example

private void doOpenFile() {
    int result = myFileChooser.showOpenDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        Path path = myFileChooser.getSelectedFile().toPath();

        try {
            String contentString = "";

            for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
                contentString += s;
            }

            jText.setText(contentString);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

private void doSaveFile() {
    int result = myFileChooser.showSaveDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        // We'll be making a mytmp.txt file, write in there, then move it to
        // the selected
        // file. This takes care of clearing that file, should there be
        // content in it.
        File targetFile = myFileChooser.getSelectedFile();

        try {
            if (!targetFile.exists()) {
                targetFile.createNewFile();
            }

            FileWriter fw = new FileWriter(targetFile);

            fw.write(jText.getText());
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

This is a late entry for folks, but below is my implementation. You will also notice I stubbed-out the ability to change the the KEYs default type: the details about which can be found in the following articles:

• Extending Identity Models and Using Integer Keys Instead of Strings
• Change Primary Key for Users in ASP.NET Identity

NOTES:
It should be noted that you cannot use Guid's for your keys. This is because under the hood they are a Struct, and as such, have no unboxing which would allow their conversion from a generic <TKey> parameter.

Very simple method:

.create:before {
content: url(image.png);
}

Works in all modern browsers and IE8+.

Edit

Don't use this on large sites though. The :before pseudo-element is horrible in terms of performance.

You can use Tommy's method in forms as well:

@using (Html.BeginForm("Action", "Controller", FormMethod.Get, new { target = "_blank" }))
{
//code
}

Below UIIImage extension will generates image object with specified color parameter.

extension UIImage {
    static func imageWithColor(tintColor: UIColor) -> UIImage {
        let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
        UIGraphicsBeginImageContextWithOptions(rect.size, false, 0)
        tintColor.setFill()
        UIRectFill(rect)
        let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return image
       }
    }

An example usage for a button can be applied for the button object as :

setupButton.setBackgroundImage(UIImage.imageWithColor(tintColor: UIColor(displayP3Red: 232/255, green: 130/255, blue: 121/255, alpha: 1.0)), for: UIControlState.highlighted)

setupButton.setBackgroundImage(UIImage.imageWithColor(tintColor: UIColor(displayP3Red: 255/255, green: 194/255, blue: 190/255, alpha: 1.0)), for: UIControlState.normal)

You can use web-based protocol handlers for the links as per https://sharepoint.stackexchange.com/questions/70178/how-does-sharepoint-2013-enable-editing-of-documents-for-chrome-and-fire-fox

Earlier PyQt .exe installers were available directly from the website download page. Now with the release of PyQt4.12 , installers have been deprecated. You can make the libraries work somehow by compiling them but that would mean going to great lengths of trouble.

Otherwise you can use the previous distributions to solve your purpose. The .exe windows installers can be downloaded from :

https://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.4/

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

There are multiple answers to this question, partly due to ambiguous question - the title is talking about classes loaded by the JVM, whereas the contents of the question says "may or may not be loaded by the JVM".

Assuming that OP needs classes that are loaded by the JVM by a given classloader, and only those classes - my need as well - there is a solution (elaborated here) that goes like this:

import java.net.URL;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.Vector;

public class CPTest {

    private static Iterator list(ClassLoader CL)
        throws NoSuchFieldException, SecurityException,
        IllegalArgumentException, IllegalAccessException {
        Class CL_class = CL.getClass();
        while (CL_class != java.lang.ClassLoader.class) {
            CL_class = CL_class.getSuperclass();
        }
        java.lang.reflect.Field ClassLoader_classes_field = CL_class
                .getDeclaredField("classes");
        ClassLoader_classes_field.setAccessible(true);
        Vector classes = (Vector) ClassLoader_classes_field.get(CL);
        return classes.iterator();
    }

    public static void main(String args[]) throws Exception {
        ClassLoader myCL = Thread.currentThread().getContextClassLoader();
        while (myCL != null) {
            System.out.println("ClassLoader: " + myCL);
            for (Iterator iter = list(myCL); iter.hasNext();) {
                System.out.println("\t" + iter.next());
            }
            myCL = myCL.getParent();
        }
    }

}

One of the neat things about it is that you can choose an arbitrary classloader you want to check. It is however likely to break should internals of classloader class change, so it is to be used as one-off diagnostic tool.

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

For example:

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

Create a struct and set two values inside and return the struct variable.

struct result {
    int a;
    char *string;
}

You have to allocate space for the char * in your program.

Centered and middled content ?

Do it this way :

<table style="width:100%">
    <tr>
        <td valign="middle" align="center">Table once ruled centering</td>
    </tr>
</table>

I fiddled it here

Ha, let me guess .. you want DIVs ..

just make your first outter DIV behave like a table-cell then style it with vertical align:middle;

<div>
    <p>I want this paragraph to be at the center, but I can't.</p>
</div>

div {
    width:500px;
    height:100px;
    background-color:aqua;
    text-align:center;
    /*  there it is */
    display:table-cell;
    vertical-align:middle;
}

SQLite doesn't support native variable syntax, but you can achieve virtually the same using an in-memory temp table.

I've used the below approach for large projects and works like a charm.

/* Create in-memory temp table for variables */
BEGIN;

PRAGMA temp_store = 2;
CREATE TEMP TABLE _Variables(Name TEXT PRIMARY KEY, RealValue REAL, IntegerValue INTEGER, BlobValue BLOB, TextValue TEXT);

/* Declaring a variable */
INSERT INTO _Variables (Name) VALUES ('VariableName');

/* Assigning a variable (pick the right storage class) */
UPDATE _Variables SET IntegerValue = ... WHERE Name = 'VariableName';

/* Getting variable value (use within expression) */
... (SELECT coalesce(RealValue, IntegerValue, BlobValue, TextValue) FROM _Variables WHERE Name = 'VariableName' LIMIT 1) ...

DROP TABLE _Variables;
END;

If you add the 'radio inline' class to the control label in the solution provided by user1938475 it should line up correctly with the other labels. Or if you're only using 'radio' like your 2nd example just include the 'radio' class.

<label class="radio control-label">Some label</label>

OR for 'radio inline'

<label class="radio-inline control-label">Some label</label>

    Gender :<br>
    <input type="radio" name="g" value="male"  <?php echo ($g=='Male')?'checked':'' ?>>male <br>
    <input type="radio" name="g" value="female"<?php echo ($g=='female')?'checked':'' ?>>female
            <?php echo $errors['g'];?>

I was able to absolutely position a right-floated element with one layer of nesting and a tricky margin:

function test() {_x000D_
  document.getElementById("box").classList.toggle("hide");_x000D_
}

.right {_x000D_
  float:right;_x000D_
}_x000D_
#box {_x000D_
  position:absolute; background:#feb;_x000D_
  width:20em; margin-left:-20em; padding:1ex;_x000D_
}_x000D_
#box.hide {_x000D_
  display:none;_x000D_
}

<div>_x000D_
  <div class="right">_x000D_
    <button onclick="test()">box</button>_x000D_
    <div id="box">Lorem ipsum dolor sit amet, consectetur adipiscing elit,_x000D_
      sed do eiusmod tempor incididunt ut labore et dolore magna aliqua._x000D_
      Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris_x000D_
      nisi ut aliquip ex ea commodo consequat._x000D_
    </div>_x000D_
  </div>_x000D_
  <p>_x000D_
    Lorem ipsum dolor sit amet, consectetur adipiscing elit,_x000D_
    sed do eiusmod tempor incididunt ut labore et dolore magna aliqua._x000D_
    Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris_x000D_
    nisi ut aliquip ex ea commodo consequat._x000D_
  </p>_x000D_
</div>

I decided to make this toggleable so you can see how it does not affect the flow of the surrounding text (run it and press the button to show/hide the floated absolute box).

Just because you have a project inside the workspace directory doesn't mean Eclipse opens it or even sees it automatically. You must use File - Import - General - Import existing project into workspace to have your project in Eclipse.

To get base URL in MVC even with subdomain www.somedomain.com/subdomain:

1. Uninstall all JDKs installed on your computer from the Java Control Panel
2. Search for C:\ProgramData\Oracle\Java and delete that directory and all files contained within. You can do this from the command line using rmdir /S C:\ProgramData\Oracle\Java
3. Then search for C:\ProgramData\Oracle and delete the oracle folder. You can do this using rmdir /S C:\ProgramData\Oracle

4. Now install JDK and set the path.

5. Run the program.You won't find the same problem anymore.

From char* to wstring:

char* str = "hello worlddd";
wstring wstr (str, str+strlen(str));

From string to wstring:

string str = "hello worlddd";
wstring wstr (str.begin(), str.end());

Note this only works well if the string being converted contains only ASCII characters.

I know this isn't a direct answer to your question, but you could also consider using clip-path, as in this question: https://stackoverflow.com/a/18208889/23341.

This is an old question and its been answered but I thought I'd put the --binary-files=text option here for anyone who wants to use it. The -I option ignores the binary file but if you want the grep to treat the binary file as a text file use --binary-files=text like so:

bash$ grep -i reset mediaLog*
Binary file mediaLog_dc1.txt matches
bash$ grep --binary-files=text -i reset mediaLog*
mediaLog_dc1.txt:2016-06-29 15:46:02,470 - Media [uploadChunk  ,315] - ERROR - ('Connection aborted.', error(104, 'Connection reset by peer'))
mediaLog_dc1.txt:ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer'))
bash$

I faced similar issue and it was caused because I had written WebServlet Path in the .java file as well as in the web.xml . Removing it from any one location works fine for me.

In the .java file

@WebServlet("/index1.jsp")

and in web.xml

<servlet>
    <servlet-name>Logout</servlet-name>
    <servlet-class>tpc.Logout</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Logout</servlet-name>
    <url-pattern>/index1.jsp</url-pattern>
</servlet-mapping>

in some case you can use annotation @Primary.

@Primary
class USA implements Country {}

This way it will be selected as the default autowire candididate, with no need to autowire-candidate on the other bean.

    UNIX socket     /var/run/mysqld/mysqld.sock
    Uptime:         1 hour 54 min 3 sec

Finally, I changed the connect_type parameter from tcp to socket and added the parameter socket in config.inc.php:

    $cfg['Servers'][$i]['host'] = 'localhost';
    $cfg['Servers'][$i]['connect_type'] = 'socket';
    $cfg['Servers'][$i]['socket'] = '/var/run/mysqld/mysqld.sock';

Linq equivalents of Map and Reduce: If you’re lucky enough to have linq then you don’t need to write your own map and reduce functions. C# 3.5 and Linq already has it albeit under different names.

• Map is Select:

  Enumerable.Range(1, 10).Select(x => x + 2);
  

• Reduce is Aggregate:

  Enumerable.Range(1, 10).Aggregate(0, (acc, x) => acc + x);
  

• Filter is Where:

  Enumerable.Range(1, 10).Where(x => x % 2 == 0);

git clone is to fetch your repositories from the remote git server.

git checkout is to checkout your desired status of your repository (like branches or particular files).

E.g., you are currently on master branch and you want to switch into develop branch.

git checkout develop_branch

E.g., you want to checkout to a particular status of a particular file

git checkout commit_point_A -- <filename>

Here is a good reference for you to learn Git, lets you understand much more easily.

This will generate 4 MB text file with random characters in current directory and its name "4mb.txt" You can change parameters to generate different sizes and names.

Neither intended for enormous files though.

In a very simple words any value which has a definite size can be treated as a value type.

Do yourself a favor by dropping the Windows compatibility layer.

The normal shortcut for entering Visual-Block mode is <C-v>.

Others have dealt with recording macros, here are a few other ideas:

Using only visual-block mode.

1. Put the cursor on the second word:

   asd |a|sd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   

2. Hit <C-v> to enter visual-block mode and expand your selection toward the bottom:

   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   

3. Hit I"<Esc> to obtain:

   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   

4. Put the cursor on the last char of the third word:

   asd "asd as|d| asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   

5. Hit <C-v> to enter visual-block mode and expand your selection toward the bottom:

   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   

6. Hit A"<Esc> to obtain:

   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   

With visual-block mode and Surround.vim.

1. Put the cursor on the second word:

   asd |a|sd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   

2. Hit <C-v> to enter visual-block mode and expand your selection toward the bottom and the right:

   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   

3. Hit S" to surround your selection with ":

   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   

With visual-line mode and :normal.

1. Hit V to select the whole line and expand it toward the bottom:

   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   

2. Execute this command: :'<,'>norm ^wi"<C-v><Esc>eea"<CR> to obtain:

   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   

   • :norm[al] allows you to execute normal mode commands on a range of lines (the '<,'> part is added automatically by Vim and means "act on the selected area")

   • ^ puts the cursor on the first char of the line

   • w moves to the next word

   • i" inserts a " before the cursor

   • <C-v><Esc> is Vim's way to input a control character in this context, here it's <Esc> used to exit insert mode

   • ee moves to the end of the next word

   • a" appends a " after the cursor

   • <CR> executes the command

   Using Surround.vim, the command above becomes

   :'<,'>norm ^wvees"<CR>
   

You can directly add a constraint for table

ALTER TABLE TableName
ADD CONSTRAINT ConstraintName PRIMARY KEY(ColumnName)
GO 

Make sure your primary key column should not have any null values.

Option 2:

you can change your SQL Management Studio Options like

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

I have written a quick example to demonstrate how to create a layout programmatically.

public class CodeLayout extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Creating a new RelativeLayout
        RelativeLayout relativeLayout = new RelativeLayout(this);

        // Defining the RelativeLayout layout parameters.
        // In this case I want to fill its parent
        RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT,
                RelativeLayout.LayoutParams.FILL_PARENT);

        // Creating a new TextView
        TextView tv = new TextView(this);
        tv.setText("Test");

        // Defining the layout parameters of the TextView
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);
        lp.addRule(RelativeLayout.CENTER_IN_PARENT);

        // Setting the parameters on the TextView
        tv.setLayoutParams(lp);

        // Adding the TextView to the RelativeLayout as a child
        relativeLayout.addView(tv);

        // Setting the RelativeLayout as our content view
        setContentView(relativeLayout, rlp);
    }
}

In theory everything should be clear as it is commented. If you don't understand something just tell me.

In my case, I tried to run from a mounted ISO. exec name are okay. I fixed the problem by copying all ISO files to the hard disk.

Client side code: I had a requirement where my nodejs webserver should work as both server as well as client, so i added below code when i need it as client, It should work fine, i am using it and working fine for me!!!

const socket = require('socket.io-client')('http://192.168.0.8:5000', {
            reconnection: true,
            reconnectionDelay: 10000
          });
    
        socket.on('connect', (data) => {
            console.log('Connected to Socket');
        });
        
        socket.on('event_name', (data) => {
            console.log("-----------------received event data from the socket io server");
        });
    
        //either 'io server disconnect' or 'io client disconnect'
        socket.on('disconnect', (reason) => {
            console.log("client disconnected");
            if (reason === 'io server disconnect') {
              // the disconnection was initiated by the server, you need to reconnect manually
              console.log("server disconnected the client, trying to reconnect");
              socket.connect();
            }else{
                console.log("trying to reconnect again with server");
            }
            // else the socket will automatically try to reconnect
          });
    
        socket.on('error', (error) => {
            console.log(error);
        });

Use this

openssl ciphers -v | awk '{print $2}' | sort | uniq

String s = "xyz";
for(int i = 0; i < s.length(); i++)
{
   char c = s.charAt(i);
}

Following the instructions given by 'cfi' works for me, although there are a few pieces they left out that you might need:

1) Your lapack directory, after unzipping, may be called lapack-X-Y (some version number), so you can just rename that to LAPACK.

cd ~/src
mv lapack-[tab] LAPACK

2) In that directory, you may need to do:

cd ~/src/LAPACK 
cp lapack_LINUX.a libflapack.a

Use the FOR command to echo a file line by line, and with the 'skip' option to miss a number of starting lines...

FOR /F "skip=1" %i in (file2.txt) do @echo %i

You could redirect the output of a batch file, containing something like...

FOR /F %%i in (file1.txt) do @echo %%i
FOR /F "skip=1" %%i in (file2.txt) do @echo %%i

Note the double % when a FOR variable is used within a batch file.

Try using:

@Html.DisplayFor(model => model.userName) <br/>
@Html.HiddenFor(model => model.userName)

Basically you should not mess the question with answer, because it is confusing.

Then you could specify what convert mean and pick one of this solution

List<Integer> keyList = Collections.list(Collections.enumeration(map.keySet()));

List<String> valueList = Collections.list(Collections.enumeration(map.values()));

8B 5D 32 is machine code

mov ebx, [ebp+32h] is assembly

lmylib.so containing 8B 5D 32 is object code

We should have the projects which include (at least) all the filtered tags, or said in a different way, exclude the ones which doesn't include all those filtered tags. So we can use Linq Except to get those tags which are not included. Then we can use Count() == 0 to have only those which excluded no tags:

var res = projects.Where(p => filteredTags.Except(p.Tags).Count() == 0);

Or we can make it slightly faster with by replacing Count() == 0 with !Any():

var res = projects.Where(p => !filteredTags.Except(p.Tags).Any());

Now that the new anaconda individual edition 2020 distribution is out, the procedure that follows is working:

Update conda in your base env:

conda update conda

Create a new environment for Python 3.8, specifying anaconda for the full distribution specification, not just the minimal environment:

conda create -n py38 python=3.8 anaconda

Activate the new environment:

conda activate py38

python --version
Python 3.8.1

Number of packages installed: 303

Or you can do:

conda create -n py38 anaconda=2020.02 python=3.8

--> UPDATE: Finally, Anaconda3-2020.07 is out with core Python 3.8.3

You can download Anaconda with Python 3.8 from https://www.anaconda.com/products/individual

The script is performed before the DOM of the body is built. Put it all into a function and call it from the onload of the body-element.

Keystore only has one password. You can change it using keytool:

keytool -storepasswd -keystore my.keystore

To change the key's password:

keytool -keypasswd  -alias <key_name> -keystore my.keystore

you need to place the opening brace after main , not before it

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(void)
{

On your aspx page define the HTML Button element with the usual suspects: runat, class, title, etc.

If this element is part of a data bound control (i.e.: grid view, etc.) you may want to use CommandName and possibly CommandArgument as attributes. Add your button's content and closing tag.

<button id="cmdAction" 
    runat="server" onserverclick="cmdAction_Click()" 
    class="Button Styles" 
    title="Does something on the server" 
    <!-- for databound controls -->
    CommandName="cmdname"> 
    CommandArgument="args..."
    >
    <!-- content -->
    <span class="ui-icon ..."></span>
    <span class="push">Click Me</span>
</button>

On the code behind page the element would call the handler that would be defined as the element's ID_Click event function.

protected void cmdAction_Click(object sender, EventArgs e)
{
: do something.
}

There are other solutions as in using custom controls, etc. Also note that I am using this live on projects in VS2K8.

Hoping this helps. Enjoy!

What about something like this, without a button:

<input type="text" placeholder="Search..." [value]="searchValue" onblur="this.value=''">

It is possible to get this working in VS Code and have the Cmder terminal be integrated (not pop up).

To do so:

1. Create an environment variable "CMDER_ROOT" pointing to your Cmder directory.
2. In (Preferences > User Settings) in VS Code add the following settings:

"terminal.integrated.shell.windows": "cmd.exe"

"terminal.integrated.shellArgs.windows": ["/k", "%CMDER_ROOT%\\vendor\\init.bat"]

select column1 as xyz,
      column2 as pqr,
.....

from TableName;

Your example Alamofire.request(.POST, "http://mywebsite.com/post-request", parameters: ["foo": "bar"]) already contains "foo=bar" string as its body. But if you really want string with custom format. You can do this:

Alamofire.request(.POST, "http://mywebsite.com/post-request", parameters: [:], encoding: .Custom({
            (convertible, params) in
            var mutableRequest = convertible.URLRequest.copy() as NSMutableURLRequest
            mutableRequest.HTTPBody = "myBodyString".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
            return (mutableRequest, nil)
        }))

Note: parameters should not be nil

UPDATE (Alamofire 4.0, Swift 3.0):

In Alamofire 4.0 API has changed. So for custom encoding we need value/object which conforms to ParameterEncoding protocol.

extension String: ParameterEncoding {

    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var request = try urlRequest.asURLRequest()
        request.httpBody = data(using: .utf8, allowLossyConversion: false)
        return request
    }

}

Alamofire.request("http://mywebsite.com/post-request", method: .post, parameters: [:], encoding: "myBody", headers: [:])

As @Sourabh already pointed out, you can check in the Google Maven link what are the packages that Google has listed out.

If you, like me, are prompted with a similar message to this Failed to resolve: com.android.support:appcompat-v7:28.0, it could be that you got there after upgrading the targetSdkVersion or compileSdkVersion.

What is basically happening is that the package is not being found, as the message correctly says. If you upgraded the SDK, check the Google Maven, to check what are the available versions of the package for the new SDK version that you want to upgrade to.

I had these dependencies (on version 27):

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'

And I had to change the SDK version and the rest of the package number:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

Now the packages are found and downloaded. Since the only available package for the 28 version of the SDK is 28.0.0 at the moment of writing this.

As an addition, you can also mix different ways of usage when calling kwargs functions:

def test(**kwargs):
    print kwargs['a']
    print kwargs['b']
    print kwargs['c']


args = { 'b': 2, 'c': 3}

test( a=1, **args )

gives this output:

1
2
3

Note that **kwargs has to be the last argument

When you make the input, set it to be readonly.

<input type="text" name="datepicker" id="datepicker" readonly="readonly" />

If you want to allow all the fonts from a folder for a specific domain then you can use this:

  <location path="assets/font">
    <system.webServer>
      <httpProtocol>
        <customHeaders>
          <add name="Access-Control-Allow-Origin" value="http://localhost:3000" />
        </customHeaders>
      </httpProtocol>
    </system.webServer>
  </location>

where assets/font is the location where all fonts are and http://localhost:3000 is the location which you want to allow.

You must to wrap your following code into a block (Either method or static).

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);

Without a block you can only declare variables and more than that assign them a value in single statement.

For method main() will be best choice for now:

public class details {
    public static void main(String[] args){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or If you want to use static block then...

public class details {
    static {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or if you want to build another method then..

public class details {
    public static void main(String[] args){
        myMethod();
    }
    private static void myMethod(){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Also worry about exception due to BufferedReader .

Are you saying that ArrayList is storing addresses of arrays because that is what is returning from the toString call, or because that's actually what you're storing?

If you have an ArrayList of arrays (e.g.

int[] arr = {1, 2, 3};
houseAddress.add(arr);

Then to print the array values you need to call Arrays.deepToString:

for (int i = 0; i < houseAddress.size(); i++) {
     System.out.println(Arrays.deepToString(houseAddress.get(i)));
}

write java program that enter elapsed time in seconds for any cycling event & the output format should be like (hour : minute : seconds ) for EX : elapsed time in 4150 seconds= 1:09:10

Swift 4:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "ExampleSegueIdentifier" {
        if let destinationVC = segue.destination as? ExampleSegueVC {
            destinationVC.exampleString = "Example"
        }
    }
}

Swift 3:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "ExampleSegueIdentifier" {
            if let destinationVC = segue.destinationViewController as? ExampleSegueVC {
                destinationVC.exampleString = "Example"
            }
        }
    }

Here's an awfully complicated solution, but it works:

public static BigDecimal roundBigDecimal(final BigDecimal input){
    return input.round(
        new MathContext(
            input.toBigInteger().toString().length(),
            RoundingMode.HALF_UP
        )
    );
}

Test Code:

List<BigDecimal> bigDecimals =
    Arrays.asList(new BigDecimal("100.12"),
        new BigDecimal("100.44"),
        new BigDecimal("100.50"),
        new BigDecimal("100.75"));
for(final BigDecimal bd : bigDecimals){
    System.out.println(roundBigDecimal(bd).toPlainString());
}

Output:

100
100
101

Many sites use AJAX/XHR/fetch to add, show, modify content dynamically and window.history API instead of in-site navigation so current URL is changed programmatically. Such sites are called SPA, short for Single Page Application.

Usual JS methods of detecting page changes

• MutationObserver (docs) to literally detect DOM changes:

  • How to change the HTML content as it's loading on the page

  • Performance of MutationObserver to detect nodes in entire DOM.

  • Simple example:

    let lastUrl = location.href; 
    new MutationObserver(() => {
      const url = location.href;
      if (url !== lastUrl) {
        lastUrl = url;
        onUrlChange();
      }
    }).observe(document, {subtree: true, childList: true});
    
    function onUrlChange() {
      console.log('URL changed!', location.href);
    }
    

• Event listener for sites that signal content change by sending a DOM event:

  • pjax:end on document used by many pjax-based sites e.g. GitHub,
    see How to run jQuery before and after a pjax load?
  • message on window used by e.g. Google search in Chrome browser,
    see Chrome extension detect Google search refresh
  • yt-navigate-finish used by Youtube,
    see How to detect page navigation on YouTube and modify its appearance seamlessly?

• Periodic checking of DOM via setInterval:
  Obviously this will work only in cases when you wait for a specific element identified by its id/selector to appear, and it won't let you universally detect new dynamically added content unless you invent some kind of fingerprinting the existing contents.

• Cloaking History API:

  let _pushState = History.prototype.pushState;
  History.prototype.pushState = function (state, title, url) {
    _pushState.call(this, state, title, url);
    console.log('URL changed', url)
  };
  

• Listening to hashchange, popstate events:

  window.addEventListener('hashchange', e => {
    console.log('URL hash changed', e);
    doSomething();
  });
  window.addEventListener('popstate', e => {
    console.log('State changed', e);
    doSomething();
  });
  

Extensions-specific methods

All above-mentioned methods can be used in a content script. Note that content scripts aren't automatically executed by the browser in case of programmatic navigation via window.history in the web page because only the URL was changed but the page itself remained the same (the content scripts run automatically only once in page lifetime).

Now let's look at the background script.

Detect URL changes in a background / event page.

There are advanced API to work with navigation: webNavigation, webRequest, but we'll use simple chrome.tabs.onUpdated event listener that sends a message to the content script:

• manifest.json:
  declare background/event page
  declare content script
  add "tabs" permission.

• background.js

  var rxLookfor = /^https?:\/\/(www\.)?google\.(com|\w\w(\.\w\w)?)\/.*?[?#&]q=/;
  chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
    if (rxLookfor.test(changeInfo.url)) {
      chrome.tabs.sendMessage(tabId, 'url-update');
    }
  });
  

• content.js

  chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
    if (msg === 'url-update') {
      // doSomething();
    }
  });
  

A different solution (not using xaml but still quite clean I think).

class ReturnKeyTextBox : TextBox
{
    protected override void OnKeyUp(KeyEventArgs e)
    {
        base.OnKeyUp(e);
        if (e.Key == Key.Return)
            GetBindingExpression(TextProperty).UpdateSource();
    }
}

According to this pattern - create transient restful resources to manage state if and when really needed. Avoid explicit sessions.

I use this too:

System.Web.HTTPContext.Current.Server.MapPath

One more reason, maybe your url include some hiden characters, such as '\n'.

If you define your url like below, this exception will raise:

url = '''
http://google.com
'''

because there are '\n' hide in the string. The url in fact become:

\nhttp://google.com\n

If the memory you are allocating is a class with a constructor that does something useful, the operator new will call that constructor and leave your object initialized.

But if you're allocating a POD or something that doesn't have a constructor that initializes the object's state, then you cannot allocate memory and initialize that memory with operator new in one operation. However, you have several options:

1. Use a stack variable instead. You can allocate and default-initialize in one step, like this:

    int vals[100] = {0}; // first element is a matter of style
   

2. use memset(). Note that if the object you are allocating is not a POD, memsetting it is a bad idea. One specific example is if you memset a class that has virtual functions, you will blow away the vtable and leave your object in an unusable state.

3. Many operating systems have calls that do what you want - allocate on a heap and initialize the data to something. A Windows example would be VirtualAlloc().

4. This is usually the best option. Avoid having to manage the memory yourself at all. You can use STL containers to do just about anything you would do with raw memory, including allocating and initializing all in one fell swoop:

    std::vector<int> myInts(100, 0); // creates a vector of 100 ints, all set to zero
   

Yes you can. Just check my fiddle for clarification. For demo purpose i kept the code in fiddle at same location. You can extract that code as shown in two different Javascript files and load them in html file.

https://jsfiddle.net/mvora/mrLmkxmo/

 /******** PUT THIS CODE IN ONE JS FILE *******/

    var secondFileFuntion = function(){
        this.name = 'XYZ';
    }

    secondFileFuntion.prototype.getSurname = function(){
     return 'ABC';
    }


    var secondFileObject = new secondFileFuntion();

    /******** Till Here *******/

    /******** PUT THIS CODE IN SECOND JS FILE *******/

    function firstFileFunction(){
      var name = secondFileObject.name;
      var surname = secondFileObject.getSurname()
      alert(name);
      alert(surname );
    }

    firstFileFunction();

If you make an object using the constructor function and trying access the property or method from it in second file, it will give you the access of properties which are present in another file.

Just take care of sequence of including these files in index.html

add CSS or class to the input element which works in select and text tags like

style="pointer-events: none;background-color:#E9ECEF"

You can copy&paste it out here: http://editor.swagger.io/#/ to check out the results.

There are also several examples in the swagger editor web with more complex security configurations which could help you.

This problem is caused (as others have stated) by model attributes being persisted into the query string - this is usually undesirable and is at risk of creating security holes as well as ridiculous query strings. My usual solution is to never use Strings for redirects in Spring MVC, instead use a RedirectView which can be configured not to expose model attributes (see: http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/web/servlet/view/RedirectView.html)

RedirectView(String url, boolean contextRelative, boolean http10Compatible, boolean exposeModelAttributes)

So I tend to have a util method which does a 'safe redirect' like:

public static RedirectView safeRedirect(String url) {
    RedirectView rv = new RedirectView(url);
    rv.setExposeModelAttributes(false);
    return rv;
}

The other option is to use bean configuration XML:

<bean id="myBean" class="org.springframework.web.servlet.view.RedirectView">
   <property name="exposeModelAttributes" value="false" />
   <property name="url" value="/myRedirect"/>
</bean>

Again, you could abstract this into its own class to avoid repetition (e.g. SafeRedirectView).

A note about 'clearing the model' - this is not the same as 'not exposing the model' in all circumstances. One site I worked on had a lot of filters which added things to the model, this meant that clearing the model before redirecting would not prevent a long query string. I would also suggest that 'not exposing model attributes' is a more semantic approach than 'clearing the model before redirecting'.

Use the LayoutInflater as I shown below.

    public View myView() {
        View v; // Creating an instance for View Object
        LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = inflater.inflate(R.layout.myview, null);

        TextView text1 = v.findViewById(R.id.dolphinTitle);
        Button btn1 = v.findViewById(R.id.dolphinMinusButton);
        TextView text2 = v.findViewById(R.id.dolphinValue);
        Button btn2 = v.findViewById(R.id.dolphinPlusButton);

        return v;
    }

Fabrício's answer is spot on; but I wanted to complement his answer with something less technical, which focusses on an analogy to help explain the concept of asynchronicity.

An Analogy...

Yesterday, the work I was doing required some information from a colleague. I rang him up; here's how the conversation went:

Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim wants a report on it, and you're the only one who knows the details about it.

Bob: Sure thing, but it'll take me around 30 minutes?

Me: That's great Bob. Give me a ring back when you've got the information!

At this point, I hung up the phone. Since I needed information from Bob to complete my report, I left the report and went for a coffee instead, then I caught up on some email. 40 minutes later (Bob is slow), Bob called back and gave me the information I needed. At this point, I resumed my work with my report, as I had all the information I needed.

Imagine if the conversation had gone like this instead;

Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim want's a report on it, and you're the only one who knows the details about it.

Bob: Sure thing, but it'll take me around 30 minutes?

Me: That's great Bob. I'll wait.

And I sat there and waited. And waited. And waited. For 40 minutes. Doing nothing but waiting. Eventually, Bob gave me the information, we hung up, and I completed my report. But I'd lost 40 minutes of productivity.

This is asynchronous vs. synchronous behavior

This is exactly what is happening in all the examples in our question. Loading an image, loading a file off disk, and requesting a page via AJAX are all slow operations (in the context of modern computing).

Rather than waiting for these slow operations to complete, JavaScript lets you register a callback function which will be executed when the slow operation has completed. In the meantime, however, JavaScript will continue to execute other code. The fact that JavaScript executes other code whilst waiting for the slow operation to complete makes the behaviorasynchronous. Had JavaScript waited around for the operation to complete before executing any other code, this would have been synchronous behavior.

var outerScopeVar;    
var img = document.createElement('img');

// Here we register the callback function.
img.onload = function() {
    // Code within this function will be executed once the image has loaded.
    outerScopeVar = this.width;
};

// But, while the image is loading, JavaScript continues executing, and
// processes the following lines of JavaScript.
img.src = 'lolcat.png';
alert(outerScopeVar);

In the code above, we're asking JavaScript to load lolcat.png, which is a sloooow operation. The callback function will be executed once this slow operation has done, but in the meantime, JavaScript will keep processing the next lines of code; i.e. alert(outerScopeVar).

This is why we see the alert showing undefined; since the alert() is processed immediately, rather than after the image has been loaded.

In order to fix our code, all we have to do is move the alert(outerScopeVar) code into the callback function. As a consequence of this, we no longer need the outerScopeVar variable declared as a global variable.

var img = document.createElement('img');

img.onload = function() {
    var localScopeVar = this.width;
    alert(localScopeVar);
};

img.src = 'lolcat.png';

You'll always see a callback is specified as a function, because that's the only* way in JavaScript to define some code, but not execute it until later.

Therefore, in all of our examples, the function() { /* Do something */ } is the callback; to fix all the examples, all we have to do is move the code which needs the response of the operation into there!

^{* Technically you can use eval() as well, but eval() is evil for this purpose}

How do I keep my caller waiting?

You might currently have some code similar to this;

function getWidthOfImage(src) {
    var outerScopeVar;

    var img = document.createElement('img');
    img.onload = function() {
        outerScopeVar = this.width;
    };
    img.src = src;
    return outerScopeVar;
}

var width = getWidthOfImage('lolcat.png');
alert(width);

However, we now know that the return outerScopeVar happens immediately; before the onload callback function has updated the variable. This leads to getWidthOfImage() returning undefined, and undefined being alerted.

To fix this, we need to allow the function calling getWidthOfImage() to register a callback, then move the alert'ing of the width to be within that callback;

function getWidthOfImage(src, cb) {     
    var img = document.createElement('img');
    img.onload = function() {
        cb(this.width);
    };
    img.src = src;
}

getWidthOfImage('lolcat.png', function (width) {
    alert(width);
});

... as before, note that we've been able to remove the global variables (in this case width).

This will work. Link to your SVG using the following pattern:

https://cdn.rawgit.com/<repo-owner>/<repo>/<branch>/path/to.svg

The downside is hardcoding the owner and repo in the path, meaning the svg will break if either of those are renamed.

I tried adding the order by to each of the queries prior to unioning like

(select * from table where distance=0 order by add_date) 
union 
(select * from table where distance>0 and distance<=5 order by add_date)

but it didn't seem to work. It didn't actually do the ordering within the rows from each select.

I think you will need to keep the order by on the outside and add the columns in the where clause to the order by, something like

(select * from table where distance=0) 
union 
(select * from table where distance>0 and distance<=5) 
order by distance, add_date

This may be a little tricky, since you want to group by ranges, but I think it should be doable.

Well, here's what worked for me:
Copy and paste the entire data folder, not just the content.
I use xampp, and the path to the data is xampp/mysql/data.

Goodluck!

Note : this example is rather artificial and mostly meant to demo a number of orthogonal features. There should seldomly be a real need to implement the state value domain itself by a full blown class, using the CRTP ( see : http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern ) like this.

Here's for a certainly simpler and likely much more common implementation use case (using a simple enum type as the states value domain), for the same state machine, and with the same test case :

https://code.google.com/p/ysharp/source/browse/trunk/StateMachinesPoC/WatchingTVSample.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Test
{
    using Machines;

    public static class WatchingTvSample
    {
        public enum Status { Unplugged, Off, On, Disposed }

        public class DeviceTransitionAttribute : TransitionAttribute
        {
            public Status From { get; set; }
            public string When { get; set; }
            public Status Goto { get; set; }
            public object With { get; set; }
        }

        // State<Status> is a shortcut for / derived from State<Status, string>,
        // which in turn is a shortcut for / derived from State<Status, string, object> :
        public class Device : State<Status>
        {
            // Executed before and after every state transition :
            protected override void OnChange(ExecutionStep step, Status value, string info, object args)
            {
                if (step == ExecutionStep.EnterState)
                {
                    // 'value' is the state value that we have transitioned FROM :
                    Console.WriteLine("\t{0} -- {1} -> {2}", value, info, this);
                }
            }

            public override string ToString() { return Value.ToString(); }
        }

        // Since 'Device' has no state graph of its own, define one for derived 'Television' :
        [DeviceTransition(From = Status.Unplugged, When = "Plug", Goto = Status.Off)]
        [DeviceTransition(From = Status.Unplugged, When = "Dispose", Goto = Status.Disposed)]
        [DeviceTransition(From = Status.Off, When = "Switch On", Goto = Status.On)]
        [DeviceTransition(From = Status.Off, When = "Unplug", Goto = Status.Unplugged)]
        [DeviceTransition(From = Status.Off, When = "Dispose", Goto = Status.Disposed)]
        [DeviceTransition(From = Status.On, When = "Switch Off", Goto = Status.Off)]
        [DeviceTransition(From = Status.On, When = "Unplug", Goto = Status.Unplugged)]
        [DeviceTransition(From = Status.On, When = "Dispose", Goto = Status.Disposed)]
        public class Television : Device { }

        public static void Run()
        {
            Console.Clear();

            // Create a television state machine instance, and return it, set in some start state :
            var tv = new Television().Start(Status.Unplugged);
            bool done;

            // Holds iff the chosen start state isn't a final state :
            System.Diagnostics.Debug.Assert(tv != null, "The chosen start state is a final state!");

            // Trigger some state transitions with no arguments
            // ('args' is ignored by this state machine's OnChange(...), anyway) :
            done =
                (

What kind of database user is it? Run select * from sys.database_principals in the database and check columns type and type_desc for that name. If it is a Windows or SQL user, go with @gbn's answer, but if it's something else (which is my untested guess based on your error message) then you have a different problem.

Edit

So it is a SQL-authenticated login. Back when we'd use sp_change_users_login to fix such logins. SQL 2008 has it as "don't use, will be deprecated", which means that the ALTER USER command should be sufficient... but it might be worth a try in this case. Used properly (it's been a while), I believe this updates the SID of the User to match that of the login.

You're trying to concatenate a string and an integer, which is incorrect.

Change print(numlist.pop(2)+" has been removed") to any of these:

Explicit int to str conversion:

print(str(numlist.pop(2)) + " has been removed")

Use , instead of +:

print(numlist.pop(2), "has been removed")

String formatting:

print("{} has been removed".format(numlist.pop(2)))

Actually, DB::connection('name')->select(..) doesnt work for me, because 'name' has to be in double quotes: "name"

Still, the select query is executed on my default connection. Still trying to figure out, how to convince Laravel to work the way it is intended: change the connection.

Edit: I figured it out. After debugging Laravels DatabaseManager it turned out my database.php (config file) (inside $this->app) was wrong. In the section "connections" I had stuff like "database" with values of the one i copied it from. In clear terms, instead of

env('DB_DATABASE', 'name')

I needed to place something like

'myNewName'

since all connections were listed with the same values for the database, username, password, etc. which of course makes little sense if I want to access at least another database name

Therefore, every time I wanted to select something from another database I always ended up in my default database

You want:

if (document.getElementById('customx').value === ""){
    //do something
}

The value property will give you a string value and you need to compare that against an empty string.

It is more efficient to send a file directly.

The base64 encoding of Content-Type: multipart/form-data adds an extra 33% overhead. If the server supports it, it is more efficient to send the files directly:

$scope.upload = function(url, file) {
    var config = { headers: { 'Content-Type': undefined },
                   transformResponse: angular.identity
                 };
    return $http.post(url, file, config);
};

When sending a POST with a File object, it is important to set 'Content-Type': undefined. The XHR send method will then detect the File object and automatically set the content type.

To send multiple files, see Doing Multiple $http.post Requests Directly from a FileList

I figured I should start with input type="file", but then found out that AngularJS can't bind to that..

The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:

Working Demo of "select-ng-files" Directive that Works with ng-model¹

angular.module("app",[]);

angular.module("app").directive("selectNgFiles", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
});

<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app="app">
    <h1>AngularJS Input `type=file` Demo</h1>
    
    <input type="file" select-ng-files ng-model="fileArray" multiple>
    
    <h2>Files</h2>
    <div ng-repeat="file in fileArray">
      {{file.name}}
    </div>
  </body>

$http.post with content type multipart/form-data

If one must send multipart/form-data:

<form role="form" enctype="multipart/form-data" name="myForm">
    <input type="text"  ng-model="fdata.UserName">
    <input type="text"  ng-model="fdata.FirstName">
    <input type="file"  select-ng-files ng-model="filesArray" multiple>
    <button type="submit" ng-click="upload()">save</button>
</form>

$scope.upload = function() {
    var fd = new FormData();
    fd.append("data", angular.toJson($scope.fdata));
    for (i=0; i<$scope.filesArray.length; i++) {
        fd.append("file"+i, $scope.filesArray[i]);
    };

    var config = { headers: {'Content-Type': undefined},
                   transformRequest: angular.identity
                 }
    return $http.post(url, fd, config);
};

When sending a POST with the FormData API, it is important to set 'Content-Type': undefined. The XHR send method will then detect the FormData object and automatically set the content type header to multipart/form-data with the proper boundary.

Use Window.location.href to take the url in javascript. it's a property that will tell you the current URL location of the browser. Setting the property to something different will redirect the page.

if (window.location.href.indexOf("?added-to-cart=555") > -1) {
    alert("found it");
}

TL;DR ...and late to the party, but that short explanation might help future googlers..

In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.

A minimal example:

df <- data.frame(a = 1:2); df$a <- 1:3

throws the error

Error in $<-.data.frame(*tmp*, a, value = 1:3) : replacement has 3 rows, data has 2

which is clear, because the vector a of df has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).

Command line usage:

for /f %f in ('dir /b c:\') do echo %f

Batch file usage:

for /f %%f in ('dir /b c:\') do echo %%f

Update: if the directory contains files with space in the names, you need to change the delimiter the for /f command is using. for example, you can use the pipe char.

for /f "delims=|" %%f in ('dir /b c:\') do echo %%f

Update 2: (quick one year and a half after the original answer :-)) If the directory name itself has a space in the name, you can use the usebackq option on the for:

for /f "usebackq delims=|" %%f in (`dir /b "c:\program files"`) do echo %%f

And if you need to use output redirection or command piping, use the escape char (^):

for /f "usebackq delims=|" %%f in (`dir /b "c:\program files" ^| findstr /i microsoft`) do echo %%f

You can do that with

var list = new List<string>{ "foo", "bar" };

Here are some other common instantiations of other common Data Structures:

Dictionary

var dictionary = new Dictionary<string, string> 
{
    { "texas",   "TX" },
    { "utah",    "UT" },
    { "florida", "FL" }
};

Array list

var array = new string[] { "foo", "bar" };

Queue

var queque = new Queue<int>(new[] { 1, 2, 3 });

Stack

var queque = new Stack<int>(new[] { 1, 2, 3 });

As you can see for the majority of cases it is merely adding the values in curly braces, or instantiating a new array followed by curly braces and values.

I had this problem recently. This was happen, because the permissions of user database. check permissions of user database, maybe the user do not have permission to write on db.

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

I just encountered the same problem and it had to do with some files being lost or corrupted. To correct the issue, just run check disk:

chkdsk /F e:

This can be run from the search windows box or from a cmd prompt. The /F fixes any issues it finds, like recovering the files. Once this finishes running, you can delete the files and folders like normal.

Syntax:

CASE value WHEN [compare_value] THEN result 
[WHEN [compare_value] THEN result ...] 
[ELSE result] 
END

Alternative: CASE WHEN [condition] THEN result [WHEN [condition] THEN result ...]

As of git v2.23.0 there's a new git restore method which is supposed to assume part of what git checkout was responsible for (even the accepted answer mentions that git checkout is quite confusing). See highlights of changes on github blog.

The default behaviour of this command is to restore the state of a working tree with the content coming from the source parameter (which in your case will be a commit hash).

So based on Greg Hewgill's answer (assuming the commit hash is c5f567) the command would look like this:

git restore --source=c5f567 file1/to/restore file2/to/restore

Or if you want to restore to the content of one commit before c5f567:

git restore --source=c5f567~1 file1/to/restore file2/to/restore

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

{{ ['foo', 'bar'|capitalize]|join }}

As you can see this works with filters and functions without needing to use set on a seperate line.

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

If you cannot install aditional applications, then you can telnet (you will need to install this feature for your windows 7 by following this) the remote server:

TELNET server_name 80

followed by:

HEAD /virtual/directory/file.ext

or

GET /virtual/directory/file.ext

depending on if you want just the header (HEAD) or the full contents (GET)

Official documentation worked for me

View -> Show Symbol -> uncheck Show End of Line.

Another simple way to do this is by using append which will allocate the slice in the process.

arr := []int{1, 2, 3}
tmp := append([]int(nil), arr...)  // Notice the ... splat
fmt.Println(tmp)
fmt.Println(arr)

Output (as expected):

[1 2 3]
[1 2 3]

So a shorthand for copying array arr would be append([]int(nil), arr...)

Basically it means "nothing" or "no type"

There are 3 basic ways that void is used:

1. Function argument: int myFunc(void) -- the function takes nothing.

2. Function return value: void myFunc(int) -- the function returns nothing

3. Generic data pointer: void* data -- 'data' is a pointer to data of unknown type, and cannot be dereferenced

Note: the void in a function argument is optional in C++, so int myFunc() is exactly the same as int myFunc(void), and it is left out completely in C#. It is always required for a return value.

Is there a way to set the session timeout programatically

There are basically three ways to set the session timeout value:

• by using the session-timeout in the standard web.xml file ~or~
• in the absence of this element, by getting the server's default session-timeout value (and thus configuring it at the server level) ~or~
• programmatically by using the HttpSession. setMaxInactiveInterval(int seconds) method in your Servlet or JSP.

But note that the later option sets the timeout value for the current session, this is not a global setting.

1. Right click your project folder.
2. Select Properties.
3. Expand Build option.
4. Select Packaging.
5. Now Clean and Build your project (Shift +F11).
6. jar file will be created at your_project_folder\dist folder.

db.<collection>.find({}, {field1: <value>, field2: <value> ...})

In your example, you can do something like:

db.students.find({}, {"roll":true, "_id":false})

Projection

The projection parameter determines which fields are returned in the matching documents. The projection parameter takes a document of the following form:

{ field1: <value>, field2: <value> ... }

The <value> can be any of the following:

1. 1 or true to include the field in the return documents.

2. 0 or false to exclude the field.

NOTE

For the _id field, you do not have to explicitly specify _id: 1 to return the _id field. The find() method always returns the _id field unless you specify _id: 0 to suppress the field.

READ MORE

Because, at least in HTML 4.01 and XHTML 1(.1), the type attribute for <script> elements is required.

In HTML 5, type is no longer required.

In fact, while you should use text/javascript in your HTML source, many servers will send the file with Content-type: application/javascript. Read more about these MIME types in RFC 4329.

Notice the difference between RFC 4329, that marked text/javascript as obsolete and recommending the use of application/javascript, and the reality in which some browsers freak out on <script> elements containing type="application/javascript" (in HTML source, not the HTTP Content-type header of the file that gets send). Recently, there was a discussion on the WHATWG mailing list about this discrepancy (HTML 5's type defaults to text/javascript), read these messages with subject Will you consider about RFC 4329?

StatTransfer is a program that moves data easily between Stata, Excel (or csv), SAS, etc. It is very user friendly (requires no programming skills). See www.stattransfer.com

This answer works for latest update on Windows 10 version 1709. Not tried with other version. But i hope it'll work.

I also ran into similar issue in my windows 10 system. I disabled Hyper-V and I tried all the answers posted here. But after that also i faced the same issue. So after lot of try, made it work using an documentation available in haxm manual. The document menntioned to use a tool named Device Guard and Credential Guard hardware readiness tool provided by Microsoft to disable Hyper-V along with some other features(Remember not only Hyper-V. So little cautios) completely. Follow the below steps to do that.

1. Download the latest version of the tool from here.
2. Unzip.
3. Open an elevated (i.e. Run as administrator) Command Prompt and run the below command by changing the extrated path and the respective version number.

@powershell -ExecutionPolicy RemoteSigned -Command "X:\path\to\dgreadiness_v3.6\DG_Readiness_Tool_v3.6.ps1 -Disable"

4. Reboot.

Then if you try to install intel haxm, it'll work.

In case of latest update check the docs available in official intel haxm development link.

Hope it helps someone.

For me, this is the best autofit and autoresize for table and its columns (use css !important ... only if you can't without)

.myclass table {
    table-layout: auto !important;
}

.myclass th, .myclass td, .myclass thead th, .myclass tbody td, .myclass tfoot td, .myclass tfoot th {
    width: auto !important;
}

Don't specify css width for table or for table columns. If table content is larger it will go over screen size to.

I got a bit grumpy about the fact nothing here seems to "just work" so I did some investigating and the result is:

Set up: QuincyKit back end that receives reports. No symbolication set up as I couldn't even begin to figure out what they were suggesting I do to make it work.

The fix: download crash reports from the server online. They're called 'crash' and by default go into the ~/Downloads/ folder. With that in mind, this script will "do the right thing" and the crash reports will go into Xcode (Organizer, device logs) and symbolication will be done.

The script:

#!/bin/bash
# Copy crash reports so that they appear in device logs in Organizer in Xcode

if [ ! -e ~/Downloads/crash ]; then 
   echo "Download a crash report and save it as $HOME/Downloads/crash before running this script."
   exit 1
fi

cd ~/Library/Logs/CrashReporter/MobileDevice/
mkdir -p actx # add crash report to xcode abbreviated
cd actx

datestr=`date "+%Y-%m-%d-%H%M%S"`

mv ~/Downloads/crash "actx-app_"$datestr"_actx.crash"

Things can be automated to where you can drag and drop in Xcode Organizer by doing two things if you do use QuincyKit/PLCR.

Firstly, you have to edit the remote script admin/actionapi.php ~line 202. It doesn't seem to get the timestamp right, so the file ends up with the name 'crash' which Xcode doesn't recognize (it wants something dot crash):

header('Content-Disposition: attachment; filename="crash'.$timestamp.'.crash"');

Secondly, in the iOS side in QuincyKit BWCrashReportTextFormatter.m ~line 176, change @"[TODO]" to @"TODO" to get around the bad characters.

    $(node).parent('div').addClass('disabled'); // just styling, appears greyed out
    $(node).on('click', function (e) {

       return c;
    }
    public static ClassicSingleton getInstance()
    {
        if(instance == null) {
            instance = new ClassicSingleton();
        }
        return instance;
    }
}

Then in the activity class:

 private ClassicSingleton cs = ClassicSingleton.getInstance();

And in the non activity class:

ClassicSingleton cs= ClassicSingleton.getInstance();
        Context c=cs.getContext();
        ImageView imageView = (ImageView) ((Activity)c).findViewById(R.id.imageView1);

You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.

So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filters.

Via Environment.OSVersion which "Gets an System.OperatingSystem object that contains the current platform identifier and version number."

They both seems to navigate to the given webpage and quoting @matt answer:

navigate().to() and get() do exactly the same thing.

Single-Page Applications are an exception to this.

The difference between these two methods comes not from their behavior, but from the behavior in the way the application works and how browser deal with it.

navigate().to() navigates to the page by changing the URL like doing forward/backward navigation.

Whereas, get() refreshes the page to changing the URL.

So, in cases where application domain changes, both the method behaves similarly. That is, page is refreshed in both the cases. But, in single-page applications, while navigate().to() do not refreshes the page, get() do.

Moreover, this is the reason browser history is getting lost when get() is used due to application being refreshed.
