I am using Chrome version 75.

add the muted property to video tag

<video id="myvid" muted>

then play it using javascript and set muted to false

var myvideo = document.getElementById("myvid");
myvideo.play();
myvideo.muted = false;

edit: need user interaction (at least click anywhere in the page to work)

There is another way of getting an element by index in jQuery using CSS :nth-of-type pseudo-class:

<script>
    // css selector that describes what you need:
    // ul li:nth-of-type(3)
    var selector = 'ul li:nth-of-type(' + index + ')';
    $(selector).css({'background-color':'#343434'});
</script>

There are other selectors that you may use with jQuery to match any element that you need.

You can use php code in files with extension .php and only there (iff other is not defined in your server settings).

Just rename your file *.html to *.php

If you want to allow php code processing in files of different format, you have two options to do that:

1) Modifying httpd.conf to allow this for all projects on your server, by adding:

AddHandler application/x-httpd-php .htm .html

2) Creating .htaccess file in your separate project top directory with:

<Files />
    AddType application/x-httpd-php .html
</Files>

For second option you need to allow use of .htaccess files in your httpd.conf, by adding the following settings:

AllowOverride All
AccessFileName .htaccess

*that is correct for Apache HTTP Server

You can reload parent window location using :

window.opener.location.href = window.opener.location.href;

try this :

Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.cat); 

I had did it and it worked

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

For asp.net core version 2.1 make sure to add the following package to fix the problem. (At least this fix the issue using SQLite)

dotnet add package Microsoft.EntityFrameworkCore.Sqlite
dotnet add package Microsoft.EntityFrameworkCore.Design

Here is the reference of the documentation using SQLite with entity framework core. https://docs.microsoft.com/en-us/ef/core/get-started/netcore/new-db-sqlite

I like prettyPhoto, IMHO it's the one that looks the best.

Accesing the Current Route Name in Controller

ie - http://localhost/your_project_name/edit

$request->segment(1);  // edit

( or )

$request->url();  // http://localhost/your_project_name/edit

try like this

css

*{
    box-sizing: border-box;
    -webkit-box-sizing: border-box;
    -msbox-sizing: border-box;
}
body{
   overflow-x: hidden;
}
img{
   max-width:100%;
}

I had this issue when i refereed a library project from a console application, and the library project was using a nuget package which is not refereed in the console application. Referring the same package in the console application helped to resolve this issue.

Seeing the Inner exception can help.

As per new feature available in Android O, font resources in XML is avilable as new feature.

To add fonts as resources, perform the following steps in the Android Studio:

1) Right-click the res folder and go to New > Android resource directory. The New Resource Directory window appears.

2) In the Resource type list, select font, and then click OK.

Note: The name of the resource directory must be font.

3) Add your font files in the font folder.

You can access the font resources with the help of a new resource type, font. For example, to access a font resource, use @font/myfont, or R.font.myfont.

eg. Typeface typeface = getResources().getFont(R.font.myfont); textView.setTypeface(typeface);

Not sure why the grep method is not working for me when using npm test. This works though. I also need to specify the test folder also for some reason.

npm test -- test/sometest.js

Here's another answer for the ASP.Net Core solution to this problem...

On the Angular side, I took this code example...

https://stackblitz.com/edit/angular-drag-n-drop-directive

... and modified it to call an HTTP Post endpoint:

  prepareFilesList(files: Array<any>) {

    const formData = new FormData();
    for (var i = 0; i < files.length; i++) { 
      formData.append("file[]", files[i]);
    }

    let URL = "https://localhost:44353/api/Users";
    this.http.post(URL, formData).subscribe(
      data => { console.log(data); },
      error => { console.log(error); }
    );

With this in place, here's the code I needed in the ASP.Net Core WebAPI controller:

[HttpPost]
public ActionResult Post()
{
  try
  {
    var files = Request.Form.Files;

    foreach (IFormFile file in files)
    {
        if (file.Length == 0)
            continue;
        
        string tempFilename = Path.Combine(Path.GetTempPath(), file.FileName);
        System.Diagnostics.Trace.WriteLine($"Saved file to: {tempFilename}");

        using (var fileStream = new FileStream(tempFilename, FileMode.Create))
        {
            file.CopyTo(fileStream);
        }
    }
    return new OkObjectResult("Yes");
  }
  catch (Exception ex)
  {
    return new BadRequestObjectResult(ex.Message);
  }
}

Shockingly simple, but I had to piece together examples from several (almost-correct) sources to get this to work properly.

1. Use Help > Troubleshoot Filters to make sure the traffic isn't getting hidden unexpectedly.
2. Look in the Log tab to see if there's a note about Chrome Group Policy hardcoding the proxy.
3. Update your question to mention whether other browsers' traffic is captured.
4. Visit http://localhost.fiddler:8888/ in Chrome; What if anything do you see?
5. Visit http://127.0.0.1:8888/ in Chrome; What if anything do you see?

If you find that steps #1 - #4 don't show anything, this means that Fiddler is unable to set your system proxy information; this might be caused by security or VPN software. (Group Policy can also prevent setting, but Fiddler will usually warn you if this is the case).

When Fiddler is capturing, click Tools > WinINET Options > LAN Settings and see whether the proxy is set properly (should point at 127.0.0.1:8888). If not, you might try running Fiddler elevated (as Administrator) to see if it makes a difference. It may be helpful to collect a trace using SysInternals' Process Monitor tool, filtered to Registry operations on the ProxyServer registry key.

If step #5 doesn't show anything, this means that you have a firewall or some other software interfering with connections to Fiddler.

dt is nullable you need to access its Value

if (datetime.HasValue)
    dt = datetime.Value;

It is important to remember that it can be NULL. That is why the nullablestruct has the HasValue property that tells you if it is NULL or not.

You can also use the null-coalescing operator ?? to assign a default value

dt = datetime ?? DateTime.Now;

This will assign the value on the right if the value on the left is NULL

u can use this :

        public void afterTextChanged(Editable s) {
            super.afterTextChanged(s);
            if (s.length() == Bank.PAN_MINIMUM_RECOGNIZABLE_LENGTH + 10) {
                Bank bank = BankUtil.findByPan(s.toString());
                if (null != bank && mNewPanEntered && !mNameDefined) {
                    mNewPanEntered = false;
                    suggestCardName(bank);
                }

private void suggestCardName(Bank bank) {
    mLastSuggestTime = System.currentTimeMillis();
    if (!bank.getName().trim().matches(getActivity().getString(R.string.bank_eghtesadnovin))) {
        inputCardNumber.setError(R.string.balance_not_enmb, true);

    }
}

Uncheck the option :

Use port 80 and 443 as alternative....

I know this is old, but here is another solution:

public static bool GetValueOrDefault<T>(this SqlDataReader Reader, string ColumnName, out T Result)
{
    try
    {
        object ColumnValue = Reader[ColumnName];

        Result = (ColumnValue!=null && ColumnValue != DBNull.Value) ? (T)ColumnValue : default(T);

        return ColumnValue!=null && ColumnValue != DBNull.Value;
    }
    catch
    {
        // Possibly an invalid cast?
        return false;
    }
}

Now, you don't care if T was value or reference type. Only if the function returns true, you have a reasonable value from the database. Usage:

...
decimal Quantity;
if (rdr.GetValueOrDefault<decimal>("YourColumnName", out Quantity))
{
    // Do something with Quantity
}

This approach is very similar to int.TryParse("123", out MyInt);

nodeEnter.append("svg:image")
.attr('x', -9)
.attr('y', -12)
.attr('width', 20)
.attr('height', 24)
.attr("xlink:href", "resources/images/check.png")

These will work with the top used emails(they match exactly the rules of each one).

Gmail
/^[a-z]((?!\.\.)([a-z\.])){4,28}[a-z0-9]@gmail.com$/i

Yahoo
/^[a-z]((?!\.\.)([\w\.])){3,30}[\w]@yahoo.com$/i

Outlook/Hotmail
/[a-z]((?!\.\.)([\w\.])){0,62}[\w]@(outlook.com|hotmail.com)$/i

Just use:

print("\033c")

This will clear the terminal window.

The accepted solution looks good, but there is one case it cannot handle:

The "onchange" event will not be triggered when the same option is reselected. So, I came up with the following improvement:

HTML

<select id="sampleSelect" >
  <option value="Home.php">Home</option>
  <option value="Contact.php">Contact</option>
  <option value="Sitemap.php">Sitemap</option>
</select>

jQuery

$("select").click(function() {
  var open = $(this).data("isopen");
  if(open) {
    window.location.href = $(this).val()
  }
  //set isopen to opposite so next time when use clicked select box
  //it wont trigger this event
  $(this).data("isopen", !open);
});

The short and clear explanation about Reactive Programming appears on Cyclejs - Reactive Programming, it uses simple and visual samples.

A [module/Component/object] is reactive means it is fully responsible for managing its own state by reacting to external events.

What is the benefit of this approach? It is Inversion of Control, mainly because [module/Component/object] is responsible for itself, improving encapsulation using private methods against public ones.

It is a good startup point, not a complete source of knowlege. From there you could jump to more complex and deep papers.

You're missing service name:

 SQL> connect username/password@hostname:port/SERVICENAME

EDIT

If you can connect to the database from other computer try running there:

select sys_context('USERENV','SERVICE_NAME') from dual

and

select sys_context('USERENV','SID') from dual

Nothing works from this tread. "forRoot" doesn't help.

Sorry. Sorted this out. I've managed to make it work by setting correct "routes" for this "forRoot" router setup routine

    import {RouterModule, Routes} from '@angular/router';    
    import {AppComponent} from './app.component';
    
    const appRoutes: Routes = [
      {path: 'UI/part1/Details', component: DetailsComponent}
    ];
    
    @NgModule({
      declarations: [
        AppComponent,
        DetailsComponent
      ],
      imports: [
        BrowserModule,
        HttpClientModule,
        RouterModule.forRoot(appRoutes)
      ],
      providers: [DetailsService],
      bootstrap: [AppComponent]
    })

Also may be helpful (spent some time to realize this) Optional route part:

    const appRoutes: Routes = [
       {path: 'UI/part1/Details', component: DetailsComponent},
       {path: ':project/UI/part1/Details', component: DetailsComponent}
    ];

Second rule allows to open URLs like
hostname/test/UI/part1/Details?id=666
and
hostname/UI/part1/Details?id=666

Been working as a frontend developer since 2012 but never stuck in a such over-complicated thing as angular2 (I have 3 years experience with enterprise level ExtJS)

Reference Resolution is described by RFC 3986 Uniform Resource Identifier (URI): Generic Syntax. And that is exactly how it supposed to work. To preserve base URI path you need to add slash at the end of the base URI and remove slash at the beginning of relative URI.

If base URI contains non-empty path, merge procedure discards it's last part (after last /). Relevant section:

5.2.3. Merge Paths

The pseudocode above refers to a "merge" routine for merging a relative-path reference with the path of the base URI. This is accomplished as follows:

• If the base URI has a defined authority component and an empty path, then return a string consisting of "/" concatenated with the reference's path; otherwise

• return a string consisting of the reference's path component appended to all but the last segment of the base URI's path (i.e., excluding any characters after the right-most "/" in the base URI path, or excluding the entire base URI path if it does not contain any "/" characters).

If relative URI starts with a slash, it is called a absolute-path relative URI. In this case merge procedure ignore all base URI path. For more information check 5.2.2. Transform References section.

A realtime priority thread can never be pre-empted by timer interrupts and runs at a higher priority than any other thread in the system. As such a CPU bound realtime priority thread can totally ruin a machine.

Creating realtime priority threads requires a privilege (SeIncreaseBasePriorityPrivilege) so it can only be done by administrative users.

For Vista and beyond, one option for applications that do require that they run at realtime priorities is to use the Multimedia Class Scheduler Service (MMCSS) and let it manage your threads priority. The MMCSS will prevent your application from using too much CPU time so you don't have to worry about tanking the machine.

I was also having the same problem. The Solution i found is ( in xcode 4.x):

Go to : Target -> "Build Phases" -> "copy bundle Resources" Then add that particular file here. If that file is already added , delete it and add it again.

clean the project and RUN. It works. :)

// this is a Jquery plugin function that fires an event when the size of an element is changed
// usage: $().sizeChanged(function(){})

(function ($) {

$.fn.sizeChanged = function (handleFunction) {
    var element = this;
    var lastWidth = element.width();
    var lastHeight = element.height();

    setInterval(function () {
        if (lastWidth === element.width()&&lastHeight === element.height())
            return;
        if (typeof (handleFunction) == 'function') {
            handleFunction({ width: lastWidth, height: lastHeight },
                           { width: element.width(), height: element.height() });
            lastWidth = element.width();
            lastHeight = element.height();
        }
    }, 100);


    return element;
};

}(jQuery));

What I'm missing in the other answers is a reference to how this relates to co- and contravariance and sub- and supertypes (that is, polymorphism) in general and to Java in particular. This may be well understood by the OP, but just in case, here it goes:

Covariance

If you have a class Automobile, then Car and Truck are their subtypes. Any Car can be assigned to a variable of type Automobile, this is well-known in OO and is called polymorphism. Covariance refers to using this same principle in scenarios with generics or delegates. Java doesn't have delegates (yet), so the term applies only to generics.

I tend to think of covariance as standard polymorphism what you would expect to work without thinking, because:

List<Car> cars;
List<Automobile> automobiles = cars;
// You'd expect this to work because Car is-a Automobile, but
// throws inconvertible types compile error.

The reason of the error is, however, correct: List<Car> does not inherit from List<Automobile> and thus cannot be assigned to each other. Only the generic type parameters have an inherit relationship. One might think that the Java compiler simply isn't smart enough to properly understand your scenario there. However, you can help the compiler by giving him a hint:

List<Car> cars;
List<? extends Automobile> automobiles = cars;   // no error

Contravariance

The reverse of co-variance is contravariance. Where in covariance the parameter types must have a subtype relationship, in contravariance they must have a supertype relationship. This can be considered as an inheritance upper-bound: any supertype is allowed up and including the specified type:

class AutoColorComparer implements Comparator<Automobile>
    public int compare(Automobile a, Automobile b) {
        // Return comparison of colors
    }

This can be used with Collections.sort:

public static <T> void sort(List<T> list, Comparator<? super T> c)

// Which you can call like this, without errors:
List<Car> cars = getListFromSomewhere();
Collections.sort(cars, new AutoColorComparer());

You could even call it with a comparer that compares objects and use it with any type.

When to use contra or co-variance?

A bit OT perhaps, you didn't ask, but it helps understanding answering your question. In general, when you get something, use covariance and when you put something, use contravariance. This is best explained in an answer to Stack Overflow question How would contravariance be used in Java generics?.

So what is it then with List<? extends Map<String, String>>

You use extends, so the rules for covariance applies. Here you have a list of maps and each item you store in the list must be a Map<string, string> or derive from it. The statement List<Map<String, String>> cannot derive from Map, but must be a Map.

Hence, the following will work, because TreeMap inherits from Map:

List<Map<String, String>> mapList = new ArrayList<Map<String, String>>();
mapList.add(new TreeMap<String, String>());

but this will not:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new TreeMap<String, String>());

and this will not work either, because it does not satisfy the covariance constraint:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new ArrayList<String>());   // This is NOT allowed, List does not implement Map

What else?

This is probably obvious, but you may have already noted that using the extends keyword only applies to that parameter and not to the rest. I.e., the following will not compile:

List<? extends Map<String, String>> mapList = new List<? extends Map<String, String>>();
mapList.add(new TreeMap<String, Element>())  // This is NOT allowed

Suppose you want to allow any type in the map, with a key as string, you can use extend on each type parameter. I.e., suppose you process XML and you want to store AttrNode, Element etc in a map, you can do something like:

List<? extends Map<String, ? extends Node>> listOfMapsOfNodes = new...;

// Now you can do:
listOfMapsOfNodes.add(new TreeMap<Sting, Element>());
listOfMapsOfNodes.add(new TreeMap<Sting, CDATASection>());

The easiest way nowadays is to use PHP configure:

# php-config --ini-dir
/usr/local/etc/php/7.4/conf.d

There's more you can find there. Example output of the --help sub command (macOS local install):

# php-config --help
Usage: /usr/local/bin/php-config [OPTION]

You can use Object.assign() to merge them into a new object:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = Object.assign({}, item, { location: response });_x000D_
_x000D_
console.log(newItem );

You can also use object spread, which is a Stage 4 proposal for ECMAScript:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = { ...item, location: response }; // or { ...response } if you want to clone response as well_x000D_
_x000D_
console.log(newItem );

I know that this question is pretty old, but I stumbled upon it recently, found a solution that I liked better, and figured I'd share it.

Now that Bootstrap 5 is available, there's a new approach that works similarly to using input-groups, but looks more like an ordinary form, without any CSS tweaks:

<div class="row g-3 align-items-center">
    <div class="col-auto">
        <label>Label:</label>
    </div>
    <div class="col">
        <input class="form-control">
    </div>
    <div class="col-auto">
        <button type="button" class="btn btn-primary">Button</button>
    </div>
</div>

The col-auto class makes those columns fit themselves to their contents (the label and the button in this case), and anything with a col class should be evenly distributed to take up the remaining space.

The problem with other answers here is that they use position: absolute;

This makes it difficult to layout the element itself in relation to the ::before pseudo-element. For example, if you wish to show an image before a link like this:

Here's how I was able to achieve the layout in the picture:

a::before {_x000D_
  content: "";_x000D_
  float: left;_x000D_
  width: 16px;_x000D_
  height: 16px;_x000D_
  margin-right: 5px;_x000D_
  background: url(../../lhsMenu/images/internal_link.png) no-repeat 0 0;_x000D_
  background-size: 80%;_x000D_
}

Note that this method allows you to scale the background image, as well as keep the ability to use margins and padding for layout.

Use, a global variable or property for assigning the value to the textbox, give the value for the variable in another class and assign it to the textbox.text in form class.

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

PHP extensions for Ubuntu 20.04 LTS (Focal Fossa)

PHP extensions for Ubuntu 18.04 LTS (Bionic)

PHP extensions for Ubuntu 16.04 LTS (Xenial)

Do it like this:

SSLSocket socket = (SSLSocket) sslFactory.createSocket(host, port);

This question has been out here a long time, but I wanted to contribute how I usually iterate through a JSON object. In the example below, I've shown a hard-coded string that contains the JSON, but the JSON string could just as easily have come from a web service or a file.

import json

def main():

    # create a simple JSON array
    jsonString = '{"key1":"value1","key2":"value2","key3":"value3"}'

    # change the JSON string into a JSON object
    jsonObject = json.loads(jsonString)

    # print the keys and values
    for key in jsonObject:
        value = jsonObject[key]
        print("The key and value are ({}) = ({})".format(key, value))

    pass

if __name__ == '__main__':
    main()

GCD is indeed lower-level than NSOperationQueue, its major advantage is that its implementation is very light-weight and focused on lock-free algorithms and performance.

NSOperationQueue does provide facilities that are not available in GCD, but they come at non-trivial cost, the implementation of NSOperationQueue is complex and heavy-weight, involves a lot of locking, and uses GCD internally only in a very minimal fashion.

If you need the facilities provided by NSOperationQueue by all means use it, but if GCD is sufficient for your needs, I would recommend using it directly for better performance, significantly lower CPU and power cost and more flexibility.

I had a similar issue but I had to consider other issues that @apaul34208 example did not tackle. In my case;

• I have a container that changed size depending on the viewport using media queries
• Text inside is dynamically generated

The proper current standard is application/json. While the default encoding is UTF-8, it is worth mentioning that it could also be UTF-16 or utf-32. When JSON is written in UTF-16 or UTF-32, binary content-transfer-encoding must be used.

There is more information about json here: https://tools.ietf.org/html/rfc4627

more information on binary transfer encoding here: https://www.w3.org/Protocols/rfc1341/5_Content-Transfer-Encoding.html

It can be done with a while loop (foreach doesn't support this):

my @arr = (1111, 2222, 3333);

while (my ($index, $element) = each(@arr))
{
   # You may need to "use feature 'say';"
   say "Index: $index, Element: $element";
}

Output:

Index: 0, Element: 1111
Index: 1, Element: 2222
Index: 2, Element: 3333

The main difference between this answer and the accepted answer is the use of setViewportView() instead of add().

How to put JTable in JScrollPane using Eclipse IDE:

1. Create JScrollPane container via Design tab.
2. Stretch JScrollPane to desired size (applies to Absolute Layout).
3. Drag and drop JTable component on top of JScrollPane (Viewport area).

In Structure > Components, table should be a child of scrollPane.

The generated code would be something like this:

JScrollPane scrollPane = new JScrollPane();
...

JTable table = new JTable();
scrollPane.setViewportView(table);

According to SQL standard you cannot use non-aggregate columns in select list. MySQL allows such usage (uless ONLY_FULL_GROUP_BY mode used) but result is not predictable.

ONLY_FULL_GROUP_BY

You should first select fromEmail, MIN(read), and then, with second query (or subquery) - Subject.

Here (http://www.dotnetperls.com/picturebox) there 3 ways to do this:

• Like you are doing.

• Using ImageLocation property of the PictureBox like:

  private void Form1_Load(object sender, EventArgs e)
  {
      PictureBox pb1 = new PictureBox();            
      pb1.ImageLocation = "../SamuderaJayaMotor.png";
      pb1.SizeMode = PictureBoxSizeMode.AutoSize;
  }
  

• Using an image from the web like:

  private void Form1_Load(object sender, EventArgs e)
  {
      PictureBox pb1 = new PictureBox();            
      pb1.ImageLocation = "http://www.dotnetperls.com/favicon.ico";
      pb1.SizeMode = PictureBoxSizeMode.AutoSize;
  }
  

And please, be sure that "../SamuderaJayaMotor.png" is the correct path of the image that you are using.

USEFUL:

Use the official Angular Update Guide select your current version and the version you wish to upgrade to for the relevant upgrade guide. https://update.angular.io/

See GitHub repository Angular CLI diff for comparing Angular CLI changes. https://github.com/cexbrayat/angular-cli-diff/

UPDATED 26/12/2018:

Use the official Angular Update Guide mentioned in the useful section above. It provides the most up to date information with links to other resources that may be useful during the upgrade.

UPDATED 08/05/2018:

Angular CLI 1.7 introduced ng update.

ng update

A new Angular CLI command to help simplify keeping your projects up to date with the latest versions. Packages can define logic which will be applied to your projects to ensure usage of latest features as well as making changes to reduce or eliminate the impact related to breaking changes.

Configuration information for ng update can be found here

1.7 to 6 update

CLI 1.7 does not support an automatic v6 update. Manually install @angular/cli via your package manager, then run the update migration schematic to finish the process.

npm install @angular/cli@^6.0.0
ng update @angular/cli --migrate-only --from=1

UPDATED 30/04/2017:

1.0 Update

You should now follow the Angular CLI migration guide

UPDATED 04/03/2017:

RC Update

You should follow the Angular CLI RC migration guide

UPDATED 20/02/2017:

Please be aware 1.0.0-beta.32 has breaking changes and has removed ng init and ng update

The pull request here states the following:

BREAKING CHANGE: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Update functionality will return to the CLI, until then manual updates of applications will need done.

The angular-cli CHANGELOG.md states the following:

BREAKING CHANGES - @angular/cli: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.

UPDATED 17/02/2017:

Angular-cli has now been added to the NPM @angular package. You should now replace the above command with the following -

Global package:

npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Local project package:

rm -rf node_modules dist # On Windows use rmdir /s /q node_modules dist
npm install --save-dev @angular/cli@latest
npm install
ng init

ORIGINAL ANSWER

You should follow the steps from the README.md on GitHub for updating angular via the angular-cli.

Here they are:

Updating angular-cli

To update angular-cli to a new version, you must update both the global package and your project's local package.

Global package:

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest

Local project package:

rm -rf node_modules dist tmp # On Windows use rmdir /s /q node_modules dist tmp
npm install --save-dev angular-cli@latest
npm install
ng init

Running ng init will check for changes in all the auto-generated files created by ng new and allow you to update yours. You are offered four choices for each changed file: y (overwrite), n (don't overwrite), d (show diff between your file and the updated file) and h (help).

Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after ng init finishes.

As others have pointed out, you cannot savely cast them, since a List<Object> isn't a List<Customer>. What you could do, is to define a view on the list that does in-place type checking. Using Google Collections that would be:

return Lists.transform(list, new Function<Object, Customer>() {
  public Customer apply(Object from) {
    if (from instanceof Customer) {
      return (Customer)from;
    }
    return null; // or throw an exception, or do something else that makes sense.
  }
});

String dateStart = "01/14/2015 08:29:58";
String dateStop = "01/15/2015 11:31:48";

//HH converts hour in 24 hours format (0-23), day calculation
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");

Date d1 = null;
Date d2 = null;

d1 = format.parse(dateStart);
d2 = format.parse(dateStop);

//in milliseconds
long diff = d2.getTime() - d1.getTime();

long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);

System.out.print(diffDays + " days, ");
System.out.print(diffHours + " hours, ");
System.out.print(diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");

If you use Roboguice you can use the EventManager in Roboguice to pass data around without using the Activity as an interface. This is quite clean IMO.

If you're not using Roboguice you can use Otto too as a event bus: http://square.github.com/otto/

Update 20150909: You can also use Green Robot Event Bus or even RxJava now too. Depends on your use case.

With iOS 8, Apple introduced a helper method to retrieve the hour, minute, second and nanosecond from an NSDate object.

Objective-C

NSDate *date = [NSDate currentDate];
NSInteger hour = 0;
NSInteger minute = 0;
NSCalendar *currentCalendar = [NSCalendar currentCalendar];
[currentCalendar getHour:&hour minute:&minute second:NULL nanosecond:NULL fromDate:date];
NSLog(@"the hour is %ld and minute is %ld", (long)hour, (long)minute);

Swift

let date = NSDate()
var hour = 0
var minute = 0
let calendar = NSCalendar.currentCalendar()
if #available(iOS 8.0, *) {
    calendar.getHour(&hour, minute: &minute, second: nil, nanosecond: nil, fromDate: date)
    print("the hour is \(hour) and minute is \(minute)")
}

Furthermore, you also have || which is the logical or, and also ; which is just a separator which doesn't care what happend to the command before.

$ false || echo "Oops, fail"
Oops, fail

$ true || echo "Will not be printed"
$  

$ true && echo "Things went well"
Things went well

$ false && echo "Will not be printed"
$

$ false ; echo "This will always run"
This will always run

Some details about this can be found here Lists of Commands in the Bash Manual.

As well as escaping quotes with backslashes, also see SO question 2911073 which explains how you could alternatively use double-quoting in a @-prefixed string:

string msg = @"I want to learn ""c#""";

Sometimes it's as simple as adding: '-ms-' in front of the style Like -ms-flex-flow: row wrap; to get it to work also.

You can use jQuery change() function

$('input').change(function(){

});

There are examples on how to use it on the API Page: http://api.jquery.com/change/

Too many big files all in one go. Windows barfs. Essentially the copying took too long because you asked too much of the computer and the file locking was locked too long and set a flag off, the flag is a semaphore error.

The computer stuffed itself and choked on it. I saw the RAM memory here get progressively filled with a Cache in RAM. Then when filled the subsystem ground to a halt with a semaphore error.

I have a workaround; copy or transfer fewer files not one humongous block. Break it down into sets of blocks and send across the files one at a time, maybe a few at a time, but not never the lot.

Just for reference, the equivalent statement for MySQL is: IFNull(Column,0).

This statement evaluates as the column value if not null, otherwise it is evaluated as 0.

You could use a MultiSet from Google Collections/Guava or a Bag from Apache Commons.

If you have a collection instead of an array, you can use addAll() to add the entire contents to the above data structure, and then apply the count() method to each value. A SortedMultiSet or SortedBag would give you the items in a defined order.

Google Collections actually has very convenient ways of going from arrays to a SortedMultiset.

If BranchA has not been pushed to a remote then you can reorder the commits using rebase and then simply merge. It's preferable to use merge over rebase when possible because it doesn't create duplicate commits.

git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

A Simpler one by just adjusting lightness/luma/brightness for contrast as is below:

import cv2

img = cv2.imread('test.jpg')
cv2.imshow('test', img)
cv2.waitKey(1000)
imghsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)


imghsv[:,:,2] = [[max(pixel - 25, 0) if pixel < 190 else min(pixel + 25, 255) for pixel in row] for row in imghsv[:,:,2]]
cv2.imshow('contrast', cv2.cvtColor(imghsv, cv2.COLOR_HSV2BGR))
cv2.waitKey(1000)
raw_input()

I just had this very issue using a root_controller bound to the body-element. Then I was using ng-view with the angular router. The problem is that angular ALWAYS creates a new scope when it inserts the html into ng-view element. As a consequence, my "check" function was defined on the parent scope of the scope that was modified by my ng-model element.

To solve the problem, just use a dedicated controller within route-loaded html content.

You can use this jQuery code which I find it eaiser to use:

$('#your_id [value=3]').attr('selected', 'true');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<select id="your_id" name="name" class="form-control input-md">_x000D_
  <option value="1">Option #1</option>_x000D_
  <option value="2">Option #2</option>_x000D_
  <option value="3">Option #3</option>_x000D_
  <option value="4">Option #4</option>_x000D_
  <option value="5">Option #5</option>_x000D_
  <option value="6">Option #6</option>_x000D_
  <option value="7">Option #7</option>_x000D_
</select>

To get rid of the default dropdown arrow use:

-moz-appearance: window; 

You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C

tl;dr (this tl;dr is from @sp00m's answer below)

$emit dispatches an event upwards ... $broadcast dispatches an event downwards

Detailed explanation

$rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it. Mostly a high level communication. Think of it as adults talking to each other in a room so the kids can't hear them.

$rootScope.$broadcast is a method that lets pretty much everything hear it. This would be the equivalent of parents yelling that dinner is ready so everyone in the house hears it.

$scope.$emit is when you want that $scope and all its parents and $rootScope to hear the event. This is a child whining to their parents at home (but not at a grocery store where other kids can hear).

$scope.$broadcast is for the $scope itself and its children. This is a child whispering to its stuffed animals so their parents can't hear.

A continue statement without a label will re-execute from the condition the innermost while or do loop, and from the update expression of the innermost for loop. It is often used to early-terminate a loop's processing and thereby avoid deeply-nested if statements. In the following example continue will get the next line, without processing the following statement in the loop.

while (getNext(line)) {
  if (line.isEmpty() || line.isComment())
    continue;
  // More code here
}

With a label, continue will re-execute from the loop with the corresponding label, rather than the innermost loop. This can be used to escape deeply-nested loops, or simply for clarity.

Sometimes continue is also used as a placeholder in order to make an empty loop body more clear.

for (count = 0; foo.moreData(); count++)
  continue;

The same statement without a label also exists in C and C++. The equivalent in Perl is next.

This type of control flow is not recommended, but if you so choose you can also use continue to simulate a limited form of goto. In the following example the continue will re-execute the empty for (;;) loop.

aLoopName: for (;;) {
  // ...
  while (someCondition)
  // ...
    if (otherCondition)
      continue aLoopName;

Like this:

if ($('input[value=""]').length > 0) {
   console.log('some fields are empty!')
}

I ran into this issue working with pyspark. As this is a python frontend for code running on a jvm, it requires type safety and using float instead of int is not an option. I worked around the issue by wrapping the pandas pd.read_csv in a function that will fill user-defined columns with user-defined fill values before casting them to the required type. Here is what I ended up using:

def custom_read_csv(file_path, custom_dtype = None, fill_values = None, **kwargs):
    if custom_dtype is None:
        return pd.read_csv(file_path, **kwargs)
    else:
        assert 'dtype' not in kwargs.keys()
        df = pd.read_csv(file_path, dtype = {}, **kwargs)
        for col, typ in custom_dtype.items():
            if fill_values is None or col not in fill_values.keys():
                fill_val = -1
            else:
                fill_val = fill_values[col]
            df[col] = df[col].fillna(fill_val).astype(typ)
    return df

The default IsSelected trigger changes 3 properties, Background, Foreground & BorderBrush. If you want to change the border as well as the background, just include this in your style trigger.

<Style TargetType="{x:Type dg:DataGridCell}">
    <Style.Triggers>
        <Trigger Property="dg:DataGridCell.IsSelected" Value="True">
            <Setter Property="Background" Value="#CCDAFF" />
            <Setter Property="BorderBrush" Value="Black" />
        </Trigger>
    </Style.Triggers>
</Style>

list has a count method:

>>> [True,True,False].count(True)
2

This is actually more efficient than sum, as well as being more explicit about the intent, so there's no reason to use sum:

In [1]: import random

In [2]: x = [random.choice([True, False]) for i in range(100)]

In [3]: %timeit x.count(True)
970 ns ± 41.1 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [4]: %timeit sum(x)
1.72 µs ± 161 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

You can check out this solution by AJ. It's pretty straightforward, just copy and paste the following lines of code.

jQuery.browser = {};
(function () {
    jQuery.browser.msie = false;
    jQuery.browser.version = 0;
    if (navigator.userAgent.match(/MSIE ([0-9]+)\./)) {
        jQuery.browser.msie = true;
        jQuery.browser.version = RegExp.$1;
    }
})();

the style is:

<style type="text/css">

</style>

hope it will work. Thanks

You can easily install it using Anaconda. At first install Anaconda or Miniconda on you system (download from here) and then install the pyqt as follow:

conda install pyqt

It works for both version of python (2 and 3).

if exist <insert file name here> (
    rem file exists
) else (
    rem file doesn't exist
)

Or on a single line (if only a single action needs to occur):

if exist <insert file name here> <action>

for example, this opens notepad on autoexec.bat, if the file exists:

if exist c:\autoexec.bat notepad c:\autoexec.bat

If you're using .NET 4.5 you can use the new async/await framework to sleep without locking the thread.

How it works is that you mark the function in need of asynchronous operations, with the async keyword. This is just a hint to the compiler. Then you use the await keyword on the line where you want your code to run asynchronously and your program will wait without locking the thread or the UI. The method you call (on the await line) has to be marked with an async keyword as well and is usually named ending with Async, as in ImportFilesAsync.

What you need to do in your example is:

1. Make sure your program has .Net Framework 4.5 as Target Framework
2. Mark your function that needs to sleep with the async keyword (see example below)
3. Add using System.Threading.Tasks; to your code.

Your code is now ready to use the Task.Delay method instead of the System.Threading.Thread.Sleep method (it is possible to use await on Task.Delay because Task.Delay is marked with async in its definition).

private async void button1_Click(object sender, EventArgs e)
{
    textBox1.Text += "\r\nThread Sleeps!";
    await Task.Delay(3000);
    textBox1.Text += "\r\nThread awakens!";
}

Here you can read more about Task.Delay and Await.

Your best shot would be with

String.format("%n")

or

System.out.printf("%n");

It is supposed to print a newline character, depending on the current platform, so it's perfect for the console.

If you are printing to a file, then it depends.

My opinion is C# and ASP.NET would be the best of the three for development that is web biased.

I doubt anyone writes new web apps in C or C++ anymore. It was done 10 years ago, and there's likely a lot of legacy code still in use, but they're not particularly well suited, there doesn't appear to be as much (ongoing) tool support, and they probably have a small active community that does web development (except perhaps for web server development). I wrote many website C++ COM objects back in the day, but C# is far more productive that there's no compelling reason to code C or C++ (in this context) unless you need to.

I do still write C++ if necessary, but it's typically for a small problem domain. e.g. communicating from C# via P/Invoke to old C-style dll's - doing some things that are downright clumsy in C# were a breeze to create a C++ COM object as a bridge.

The nice thing with C# is that you can also easily transfer into writing Windows and Console apps and stay in C#. With Mono you're also not limited to Windows (although you may be limited to which libraries you use).

Anyways this is all from a web-biased perspective. If you asked about embedded devices I'd say C or C++. You could argue none of these are suited for web development, but C#/ASP.NET is pretty slick, it works well, there are heaps of online resources, a huge community, and free dev tools.

So from a real-world perspective, picking only one of C#, C++ and C as requested, as a general rule, you're better to stick with C#.

Use Query.setParameterList(), Javadoc here.

There are four variants to pick from.

Try this -

 select * from table where id in (3,4) or [name] in ('andy','paul');

You can also use another built-in template default_if_none

{{ profile.user.first_name|default_if_none:"--" }}

First, I see you're using an explicit $.parseJSON(). If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.

To iterate through the first item in the array you've got there, use code like this:

var firstItem = response.d[0];

for(key in firstItem) {
  console.log(key + ':' + firstItem[key]);
}

If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d and then use this code inside that outer loop.

You'll get that error once your numbers are greater than sys.maxsize:

>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

You can confirm this by checking:

>>> import sys
>>> sys.maxsize
2147483647

To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:

>>> preds = np.zeros((1, 3))

NODE USERS (REACT,EXPRESS) FOLLOW THESE STEPS

1. npm install base-64 --save
2. import { encode } from "base-64";

3.  const response = await fetch(URL, {
     method: 'post',
     headers: new Headers({
       'Authorization': 'Basic ' + encode(username + ":" + password),
       'Content-Type': 'application/json'
     }),
     body: JSON.stringify({
       "PassengerMobile": "xxxxxxxxxxxx",
       "Password": "xxxxxxx"
     })
   });
   const posts = await response.json();
   

4. Don't forget to define this whole function as async

In iOS,

• Open Anaconda Navigator
• Launch Spyder
• Click on the tab "Consoles" (menu bar)
• Then, "New Console"
• Finally, in the console window, type conda update spyder

Your computer is going to start downloading and installing the new version. After finishing, just restart Spyder and that's it.

Often data on webpages is in the form of an XML table. You can read an XML table into R using the package XML.

In this package, the function

readHTMLTable(<url>)

will look through a page for XML tables and return a list of data frames (one for each table found).

If you want to add a custom highlighted color to your cell (and your cell contains buttons,labels, images,etc..) I followed the next steps:

For example if you want a selected yellow color:

1) Create a view that fits all the cell with 20% opacity (with yellow color) called for example backgroundselectedView

2) In the cell controller write this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
     self.backgroundselectedView.alpha=1;
    [super touchesBegan:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.backgroundselectedView.alpha=0;
    [super touchesEnded:touches withEvent:event];
}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.backgroundSelectedImage.alpha=0;
    [super touchesCancelled:touches withEvent:event];
}

This recursive function concatenates array of querysets into one queryset.

def merge_query(ar):
    if len(ar) ==0:
        return [ar]
    while len(ar)>1:
        tmp=ar[0] | ar[1]
        ar[0]=tmp
        ar.pop(1)
        return ar

To add up to Kevin and Lex's answers:

We had a similar situation at work where both the developers and the build server had Visual Studio 2013. Our solution had a VS 2013 C++ project and compiled fine when built on developer's machine or on the build server within the IDE. The issue was when triggering builds using TFS build definitions. We were still using an old build template (version 11.1) instead of 12.0. Fortunately, a simple attribute addition to the template xaml file solved the issue. In the Sequence portion "Compile the Project", there is a xaml node that starts with

mtbwa:MSBuild CommandLineArgument=....

You can add a "ToolPath" attribute and point it to the right path of the MSBuild.exe you wish to invoke, based on Kevin's answer. For instance:

ToolPath="C:\Program Files (x86)\MSBuild\12.0\Bin"

I had the same error here but with glassfish server. Maybe it can help. I needed to configure the glassfish-web.xml file with the content inside the <resources> from glassfish-resources.xml. As I got another error I could find this annotation in the server log:

Caused by: java.lang.RuntimeException: Error in parsing WEB-INF/glassfish-web.xml for archive [file:/C:/Users/Win/Documents/NetBeansProjects/svad/build/web/]: The xml element should be [glassfish-web-app] rather than [resources]

All I did then was to change the <resources> tag and apply <glassfish-web-app> in the glassfish-web.xml file.

Can you try a custom CSS aside the bootstrap CSS to see if any changes. Try

.move-rigth{
    display: block;
    float: right;
}

If it works then you can try manipulating what you have or adding other formatting to this and achieving what you desire. Because you are using bootstrap doesn't mean if it doesn't offer you what you want then you just manage it. You are working with your codes and so you command it to do as you say. Cheers!

Select top 1 * from foo where id > 4 order by id asc

I'm debugging an issue I'm having with SSL connecting to a database (MySQL RDS) using an ORM called, Prisma. The database connection string requires a PKCS12 (.p12) file (if interested, described here), which brought me here.

I know the question has been answered, but I found the following steps (in Github Issue#2676) to be helpful for creating a .p12 file and wanted to share. Good luck!

1. Generate 2048-bit RSA private key:

   openssl genrsa -out key.pem 2048

2. Generate a Certificate Signing Request:

   openssl req -new -sha256 -key key.pem -out csr.csr

3. Generate a self-signed x509 certificate suitable for use on web servers.

   openssl req -x509 -sha256 -days 365 -key key.pem -in csr.csr -out certificate.pem

4. Create SSL identity file in PKCS12 as mentioned here

   openssl pkcs12 -export -out client-identity.p12 -inkey key.pem -in certificate.pem

You can use the following code :

<!DOCTYPE html>
<html>
    <body onLoad="triggerJS();">

    <script>
        function triggerJS(){
        location.replace("http://www.google.com");
        /*
        location.assign("New_WebSite_Url");
        //Use assign() instead of replace if you want to have the first page in the history (i.e if you want the user to be able to navigate back when New_WebSite_Url is loaded)
        */
        }
    </script>

    </body>
</html>

the $.Browser.msie is not on the latest JQuery anymore... you have to use the $.support

like below:

 <script>

     (function ($) {
         $.support.placeholder = ('placeholder' in document.createElement('input'));
     })(jQuery);


     //fix for IE7 and IE8
     $(function () {
         if (!$.support.placeholder) {
             $("[placeholder]").focus(function () {
                 if ($(this).val() == $(this).attr("placeholder")) $(this).val("");
             }).blur(function () {
                 if ($(this).val() == "") $(this).val($(this).attr("placeholder"));
             }).blur();

             $("[placeholder]").parents("form").submit(function () {
                 $(this).find('[placeholder]').each(function() {
                     if ($(this).val() == $(this).attr("placeholder")) {
                         $(this).val("");
                     }
                 });
             });
         }
     });
 </script>

You can just set "focusable" and "focusable in touch mode" to value true on the first TextView of the layout. In this way when the activity starts the TextView will be focused but , due to its nature, you will see nothing focused on the screen and ,of course, there will be no keyboard displayed...

If you don't want execute assembly goal on package, you can use next command:

mvn package assembly:single

Here package is keyword.

grep -q "something" file
[[ !? -eq 0 ]] && echo "yes" || echo "no"

You need to use the openssl pkcs12 -export -chain -in server.crt -CAfile ...

See https://www.openssl.org/docs/apps/pkcs12.html

I know this is older one, but doesn't carry the simple answer, I needed this method for my coding so I added here, simple to use.

public static String toTitleCase(String input) {
    input = input.toLowerCase();
    char c =  input.charAt(0);
    String s = new String("" + c);
    String f = s.toUpperCase();
    return f + input.substring(1);
}

Let's discuss why an "object not found" error can be thrown in R in addition to explaining what it means. What it means (to many) is obvious: the variable in question, at least according to the R interpreter, has not yet been defined, but if you see your object in your code there can be multiple reasons for why this is happening:

1. check syntax of your declarations. If you mis-typed even one letter or used upper case instead of lower case in a later calling statement, then it won't match your original declaration and this error will occur.

2. Are you getting this error in a notebook or markdown document? You may simply need to re-run an earlier cell that has your declarations before running the current cell where you are calling the variable.

3. Are you trying to knit your R document and the variable works find when you run the cells but not when you knit the cells? If so - then you want to examine the snippet I am providing below for a possible side effect that triggers this error:

   {r sourceDataProb1, echo=F, eval=F} # some code here

The above snippet is from the beginning of an R markdown cell. If eval and echo are both set to False this can trigger an error when you try to knit the document. To clarify. I had a use case where I had left these flags as False because I thought i did not want my code echoed or its results to show in the markdown HTML I was generating. But since the variable was then used in later cells, this caused an error during knitting. Simple trial and error with T/F TRUE/FALSE flags can establish if this is the source of your error when it occurs in knitting an R markdown document from RStudio.

Lastly: did you remove the variable or clear it from memory after declaring it?

• rm() removes the variable
• hitting the broom icon in the evironment window of RStudio clearls everything in the current working environment
• ls() can help you see what is active right now to look for a missing declaration.
• exists("x") - as mentioned by another poster, can help you test a specific value in an environment with a very lengthy list of active variables

You can use following code which generate pdf file in background as like on button click and then would popup in brwoser with SaveAs and cancel option.

Warning[] warnings;
        string[] streamIds;
        string mimeType = string.Empty;
        string encoding = string.Empty;`enter code here`
        string extension = string.Empty;
        DataSet dsGrpSum, dsActPlan, dsProfitDetails,
            dsProfitSum, dsSumHeader, dsDetailsHeader, dsBudCom = null;

    enter code here

//This is optional if you have parameter then you can add parameters as much as you want
ReportParameter[] param = new ReportParameter[5];
            param[0] = new ReportParameter("Report_Parameter_0", "1st Para", true);
            param[1] = new ReportParameter("Report_Parameter_1", "2nd Para", true);
            param[2] = new ReportParameter("Report_Parameter_2", "3rd Para", true);
            param[3] = new ReportParameter("Report_Parameter_3", "4th Para", true);
            param[4] = new ReportParameter("Report_Parameter_4", "5th Para");

            DataSet  dsData= "Fill this dataset with your data";
            ReportDataSource rdsAct = new ReportDataSource("RptActDataSet_usp_GroupAccntDetails", dsActPlan.Tables[0]);
            ReportViewer viewer = new ReportViewer();
            viewer.LocalReport.Refresh();
            viewer.LocalReport.ReportPath = "Reports/AcctPlan.rdlc"; //This is your rdlc name.
            viewer.LocalReport.SetParameters(param);
            viewer.LocalReport.DataSources.Add(rdsAct); // Add  datasource here         
            byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
            // byte[] bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
            // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.          
            // System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Buffer = true;
            Response.Clear();
            Response.ContentType = mimeType;
            Response.AddHeader("content-disposition", "attachment; filename= filename" + "." + extension);
            Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file  
            Response.Flush(); // send it to the client to download  
            Response.End();

Maybe you can use arrow function (ES6+) or the simple old function declaration.

Normal function declaration type (Not ES6+):

<link href="#" onClick={function(event){ func1(event); func2();}}>Trigger here</link>

Anonymous function or arrow function type (ES6+)

<link href="#" onClick={(event) => { func1(event); func2();}}>Trigger here</link>

The second one is the shortest road that I know. Hope it helps you!

I also had same problem then I found this on there documentation page

So if you want to create a project by name of test_laravel in directory /Applications/MAMP/htdocs/ then what you need to do is

go to your project parent directory

cd /Applications/MAMP/htdocs

and fire this command

composer create-project laravel/laravel test_laravel --prefer-dist

that's it, this is really easy and it also creates Application Key automatically for you

1. Right click to the project and select the property menu item
2. goto C/C++ -> Precompiled Headers
3. Select Not Using Precompiled Headers

I added below two lines in gradle.properties file

android.useAndroidX=true
android.enableJetifier=true

then I got the following error

error: package android.support.v7.app does not exist
import android.support.v7.app.AlertDialog;
                         ^
                         

I have removed the imports and added below line

import static android.app.AlertDialog.*;

And the classes which are extended from AppCompactActivity, added the below line. (For these errors you just need to press alt+enter in android studio which will import the correct library for you. Like this you can resolve all the errors)

import androidx.appcompat.app.AppCompatActivity;

In your xml file if you have used any

<android.support.v7.widget.Toolbar 

replace it with androidx.appcompat.widget.Toolbar

then in your java code

import androidx.appcompat.widget.Toolbar;

Try the following command:

openssl ciphers

This should produce a list of all of the ciphers supported in your version of openssl.

To see just a particular set of ciphers (e.g. just sslv3 ciphers) try:

openssl ciphers -ssl3

See https://www.openssl.org/docs/apps/ciphers.html for more info.

For sentOs, it's works for me At first stop service by sudo service jenkins stop

Than remove by sudo yum remove jenkins

As Jacob mentioned, the CentOS packages repo appears to only have PHP 5.3 available at the moment. But these commands seemed to work for me...

rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
yum remove php-common       # Need to remove this, otherwise it conflicts
yum install php56w
yum install php56w-mysql
yum install php56w-common
yum install php56w-pdo
yum install php56w-opcache
php --version               # Verify version has been upgraded

You can alternatively use php54w or php55w if required.

CAUTION!
This may potentially break your website if it doesn't fully resolve all your dependencies, so you may need a couple of extra packages in some cases. See here for a list of other PHP 5.6 modules that are available.

If you encounter a problem and need to reset back to the default, you can use these commands:

sudo yum remove php56w
sudo yum remove php56w-common
sudo yum install php-common
sudo yum install php-mysql
sudo yum install php

(Thanks Fabrizio Bartolomucci)

I wanted to have multiple datasources in the app config. So after setting up a section in the app.config i swaped out the datasource and then pass it into the dbcontext as the connection string.

//Get the key/value connection string from app config  
var sect = (NameValueCollection)ConfigurationManager.GetSection("section");  
var val = sect["New DataSource"].ToString();

//Get the original connection string with the full payload  
var entityCnxStringBuilder = new EntityConnectionStringBuilder(ConfigurationManager.ConnectionStrings["OriginalStringBuiltByADO.Net"].ConnectionString);     

//Swap out the provider specific connection string  
entityCnxStringBuilder.ProviderConnectionString = val;

//Return the payload with the change in connection string.   
return entityCnxStringBuilder.ConnectionString;

This took me a bit to figure out. I hope it helps someone out. I was making it way too complicated. before this.

To add all file at a time, use git add -A

To check git whole status, use git log

Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

for(Person p : oldList) {
    newList.add(p.clone());
}

Assuming clone is correctly overriden inPerson.

You can use \centering with your parbox to do this.

Contrary to Mark Novakowski answer, which for some reason has been upvoted by many, yes, it is a valid and satisfiable request.

In fact the standard, as Wrikken pointed out, makes just such an example. In practice, Apache responds to such requests as expected (with a 206 code), and this is exactly what I use to implement progressive download, that is, only get the tail of a long log file which grows in real time with polling.

I'm not sure, but you may be able to just use

$("#filecontainer #choose_pic").click(function() {
    // do something here
});

Either that or you could just add a <script> tag into the iframe (if you have access to the code inside), and then use window.parent.DoSomething() in the frame, with the code

function DoSomething() {
    // do something here
}

in the parent. If none of those work, try window.postMessage. Here is some info on that.

make sure the submit button is not of type "submit", make it a button. Then use the onclick event to trigger some javascript. There you can do whatever you want before you actually post your data.

Definitely, we cannot override static methods in Java. Because JVM resolves correct overridden method based upon the object at run-time by using dynamic binding in Java.

However, the static method in Java is associated with Class rather than the object and resolved and bonded during compile time.

The accepted answer is through but there is official explanation on this:

The WebApplicationContext is an extension of the plain ApplicationContext that has some extra features necessary for web applications. It differs from a normal ApplicationContext in that it is capable of resolving themes (see Using themes), and that it knows which Servlet it is associated with (by having a link to the ServletContext). The WebApplicationContext is bound in the ServletContext, and by using static methods on the RequestContextUtils class you can always look up the WebApplicationContext if you need access to it.

Cited from Spring web framework reference

By the way servlet and root context are both webApplicationContext:

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

The problem was with the QuickText plugin. After removing it, indent worked as normal.

You could write an extension method:

public static void InvokeIfRequired(this Control c, Action<Control> action)
{
    if(c.InvokeRequired)
    {
        c.Invoke(new Action(() => action(c)));
    }
    else
    {
        action(c);
    }
}

And use it like this:

object1.InvokeIfRequired(c => { c.Visible = true; });

EDIT: As Simpzon points out in the comments you could also change the signature to:

public static void InvokeIfRequired<T>(this T c, Action<T> action) 
    where T : Control

Prepend functions with the '@' symbol to suppress certain errors, as opposed to turning off all error reporting.

More information: http://php.net/manual/en/language.operators.errorcontrol.php

PHP supports one error control operator: the at sign (@). When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.

@fsockopen();

This is the simplest solution:

SELECT quote FROM quotes ORDER BY RAND() 

Although it is not the most efficient. This one is a better solution.

you can use sequence slicing syntax i.e

paramdata[:5] # first five records
paramdata[-5:] # last five records
paramdata[:] # all records

sometimes the dataframe might not fit in the screen buffer in which case you are probably better off either printing a small subset or exporting it to something else, plot or (csv again)

Why myList[1] is considered a 'str' object?

Because it is a string. What else is 'from form', if not a string? (Actually, strings are sequences too, i.e. they can be indexed, sliced, iterated, etc. as well - but that's part of the str class and doesn't make it a list or something).

mList[1] returns the first item in the list 'from form'

If you mean that myList is 'from form', no it's not!!! The second (indexing starts at 0) element is 'from form'. That's a BIG difference. It's the difference between a house and a person.

Also, myList doesn't have to be a list from your short code sample - it could be anything that accepts 1 as index - a dict with 1 as index, a list, a tuple, most other sequences, etc. But that's irrelevant.

but I cannot append to item 1 in the list myList

Of course not, because it's a string and you can't append to string. String are immutable. You can concatenate (as in, "there's a new object that consists of these two") strings. But you cannot append (as in, "this specific object now has this at the end") to them.

In Swift use this,

If you wants to have pull to refresh in WebView,

So try this code:

override func viewDidLoad() {
    super.viewDidLoad()
    addPullToRefreshToWebView()
}

func addPullToRefreshToWebView(){
    var refreshController:UIRefreshControl = UIRefreshControl()

    refreshController.bounds = CGRectMake(0, 50, refreshController.bounds.size.width, refreshController.bounds.size.height) // Change position of refresh view
    refreshController.addTarget(self, action: Selector("refreshWebView:"), forControlEvents: UIControlEvents.ValueChanged)
    refreshController.attributedTitle = NSAttributedString(string: "Pull down to refresh...")
    YourWebView.scrollView.addSubview(refreshController)

}

func refreshWebView(refresh:UIRefreshControl){
    YourWebView.reload()
    refresh.endRefreshing()
}

You can use credential helpers.

git config --global credential.helper 'cache --timeout=x'

where x is the number of seconds.

None of the answers return false for empty strings, a fix for that...

function is_numeric(n)
{
 return (n != '' && !isNaN(parseFloat(n)) && isFinite(n));
}

Try this.

string output1 = Encoding.ASCII.GetString(byteArray, 0, byteArray.Length)

You can implement some basic Calculus and create a universal function for moving array element from one position to the other.

For JavaScript it looks like this:

function magicFunction (targetArray, indexFrom, indexTo) { 

    targetElement = targetArray[indexFrom]; 
    magicIncrement = (indexTo - indexFrom) / Math.abs (indexTo - indexFrom); 

    for (Element = indexFrom; Element != indexTo; Element += magicIncrement){ 
        targetArray[Element] = targetArray[Element + magicIncrement]; 
    } 

    targetArray[indexTo] = targetElement; 

}

Check out "moving array elements" at "gloommatter" for detailed explanation.

The error arises because gnuplot is trying to interpret the word "plot" as the filename to plot, but you haven't assigned any strings to a variable named "plot" (which is good – that would be super confusing).

Note: The first() method doesn't throw an exception as described in the original question. If you're getting this kind of exception, there is another error in your code.

The correct way to user first() and check for a result:

$user = User::where('mobile', Input::get('mobile'))->first(); // model or null
if (!$user) {
   // Do stuff if it doesn't exist.
}

Other techniques (not recommended, unnecessary overhead):

$user = User::where('mobile', Input::get('mobile'))->get();

if (!$user->isEmpty()){
    $firstUser = $user->first()
}

or

try {
    $user = User::where('mobile', Input::get('mobile'))->firstOrFail();
    // Do stuff when user exists.
} catch (ErrorException $e) {
    // Do stuff if it doesn't exist.
}

or

// Use either one of the below. 
$users = User::where('mobile', Input::get('mobile'))->get(); //Collection

if (count($users)){
    // Use the collection, to get the first item use $users->first().
    // Use the model if you used ->first();
}

Each one is a different way to get your required result.

With Oracle 12c (June 2013), you are able to use it like the following.

SELECT * FROM   MYTABLE
--ORDER BY COLUMNNAME -OPTIONAL          
OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY

There's a list. There is also a putative C++ frontend on splint.

I'd start with something like this (and if there is something wrong with my code, I'd of course appreciate any comment):

public class ItemsList extends ListActivity {

private ItemsAdapter adapter;

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

    setContentView(R.layout.items_list);

    this.adapter = new ItemsAdapter(this, R.layout.items_list_item, ItemManager.getLoadedItems());
    setListAdapter(this.adapter);
}

private class ItemsAdapter extends ArrayAdapter<Item> {

    private Item[] items;

    public ItemsAdapter(Context context, int textViewResourceId, Item[] items) {
        super(context, textViewResourceId, items);
        this.items = items;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.items_list_item, null);
        }

        Item it = items[position];
        if (it != null) {
            ImageView iv = (ImageView) v.findViewById(R.id.list_item_image);
            if (iv != null) {
                iv.setImageDrawable(it.getImage());
            }
        }

        return v;
    }
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    this.adapter.getItem(position).click(this.getApplicationContext());
}
}

E.g. extending ArrayAdapter with own type of Items (holding information about your pictures) and overriden getView() method, that prepares view for items within list. There is also method add() on ArrayAdapter to add items to the end of the list.

R.layout.items_list is simple layout with ListView

R.layout.items_list_item is layout representing one item in list

If you have a multi-dimensional array, len() might not give you the value you are looking for. For instance:

import numpy as np
a = np.arange(10).reshape(2, 5)
print len(a) == 2

This code block will return true, telling you the size of the array is 2. However, there are in fact 10 elements in this 2D array. In the case of multi-dimensional arrays, len() gives you the length of the first dimension of the array i.e.

import numpy as np
len(a) == np.shape(a)[0]

To get the number of elements in a multi-dimensional array of arbitrary shape:

import numpy as np
size = 1
for dim in np.shape(a): size *= dim

I found this on another site not sure if it works or not.

Application.Wait Now + 1/(24*60*60.0*2)

the numerical value 1 = 1 day

1/24 is one hour

1/(24*60) is one minute

so 1/(24*60*60*2) is 1/2 second

You need to use a decimal point somewhere to force a floating point number

Not sure if this will work worth a shot for milliseconds

It's very simple to implement - you should use TestContext property and TestPropertyAttribute.

Example

public TestContext TestContext { get; set; }
private List<string> GetProperties()
{
    return TestContext.Properties
        .Cast<KeyValuePair<string, object>>()
        .Where(_ => _.Key.StartsWith("par"))
        .Select(_ => _.Value as string)
        .ToList();
}

//usage
[TestMethod]
[TestProperty("par1", "http://getbootstrap.com/components/")]
[TestProperty("par2", "http://www.wsj.com/europe")]
public void SomeTest()
{
    var pars = GetProperties();
    //...
}

EDIT:

I prepared few extension methods to simplify access to the TestContext property and act like we have several test cases. See example with processing simple test properties here:

[TestMethod]
[TestProperty("fileName1", @".\test_file1")]
[TestProperty("fileName2", @".\test_file2")]
[TestProperty("fileName3", @".\test_file3")]
public void TestMethod3()
{
    TestContext.GetMany<string>("fileName").ForEach(fileName =>
    {
        //Arrange
        var f = new FileInfo(fileName);

        //Act
        var isExists = f.Exists;

        //Asssert
        Assert.IsFalse(isExists);
    });
}

and example with creating complex test objects:

[TestMethod]
//Case 1
[TestProperty(nameof(FileDescriptor.FileVersionId), "673C9C2D-A29E-4ACC-90D4-67C52FBA84E4")]
//...
public void TestMethod2()
{
    //Arrange
    TestContext.For<FileDescriptor>().Fill(fi => fi.FileVersionId).Fill(fi => fi.Extension).Fill(fi => fi.Name).Fill(fi => fi.CreatedOn, new CultureInfo("en-US", false)).Fill(fi => fi.AccessPolicy)
        .ForEach(fileInfo =>
        {
            //Act
            var fileInfoString = fileInfo.ToString();

            //Assert
            Assert.AreEqual($"Id: {fileInfo.FileVersionId}; Ext: {fileInfo.Extension}; Name: {fileInfo.Name}; Created: {fileInfo.CreatedOn}; AccessPolicy: {fileInfo.AccessPolicy};", fileInfoString);
        });
}

Take a look to the extension methods and set of samples for more details.

Use df.count() to get the number of rows.

How to mock void methods with mockito - there are two options:

1. doAnswer - If we want our mocked void method to do something (mock the behavior despite being void).
2. doThrow - Then there is Mockito.doThrow() if you want to throw an exception from the mocked void method.

Following is an example of how to use it (not an ideal usecase but just wanted to illustrate the basic usage).

@Test
public void testUpdate() {

    doAnswer(new Answer<Void>() {

        @Override
        public Void answer(InvocationOnMock invocation) throws Throwable {
            Object[] arguments = invocation.getArguments();
            if (arguments != null && arguments.length > 1 && arguments[0] != null && arguments[1] != null) {

                Customer customer = (Customer) arguments[0];
                String email = (String) arguments[1];
                customer.setEmail(email);

            }
            return null;
        }
    }).when(daoMock).updateEmail(any(Customer.class), any(String.class));

    // calling the method under test
    Customer customer = service.changeEmail("[email protected]", "[email protected]");

    //some asserts
    assertThat(customer, is(notNullValue()));
    assertThat(customer.getEmail(), is(equalTo("[email protected]")));

}

@Test(expected = RuntimeException.class)
public void testUpdate_throwsException() {

    doThrow(RuntimeException.class).when(daoMock).updateEmail(any(Customer.class), any(String.class));

    // calling the method under test
    Customer customer = service.changeEmail("[email protected]", "[email protected]");

}
}

You could find more details on how to mock and test void methods with Mockito in my post How to mock with Mockito (A comprehensive guide with examples)

The SQL WITH clause was introduced by Oracle in the Oracle 9i release 2 database. The SQL WITH clause allows you to give a sub-query block a name (a process also called sub-query refactoring), which can be referenced in several places within the main SQL query. The name assigned to the sub-query is treated as though it was an inline view or table. The SQL WITH clause is basically a drop-in replacement to the normal sub-query.

Syntax For The SQL WITH Clause

The following is the syntax of the SQL WITH clause when using a single sub-query alias.

WITH <alias_name> AS (sql_subquery_statement)
SELECT column_list FROM <alias_name>[,table_name]
[WHERE <join_condition>]

When using multiple sub-query aliases, the syntax is as follows.

WITH <alias_name_A> AS (sql_subquery_statement),
<alias_name_B> AS(sql_subquery_statement_from_alias_name_A
or sql_subquery_statement )
SELECT <column_list>
FROM <alias_name_A>, <alias_name_B> [,table_names]
[WHERE <join_condition>]

In the syntax documentation above, the occurrences of alias_name is a meaningful name you would give to the sub-query after the AS clause. Each sub-query should be separated with a comma Example for WITH statement. The rest of the queries follow the standard formats for simple and complex SQL SELECT queries.

I had a similar problem recently and found out, that client_max_body_size 0; can solve such an issue. This will set client_max_body_size to no limit. But the best practice is to improve your code, so there is no need to increase this limit.

//display sample reg form in notepad.txt
using (StreamWriter stream = new FileInfo("D:\\tt.txt").AppendText())//ur file location//.AppendText())
{
   stream.WriteLine("Name :" + textBox1.Text);//display textbox data in notepad
   stream.WriteLine("DOB : " + dateTimePicker1.Text);//display datepicker data in notepad
   stream.WriteLine("DEP:" + comboBox1.SelectedItem.ToString());
   stream.WriteLine("EXM :" + listBox1.SelectedItem.ToString());
}

You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

Swift 3 Implementation

    import Foundation
class KeyboardStateListener: NSObject
{
    static let shared = KeyboardStateListener()
    var isVisible = false

    func start() {
        NotificationCenter.default.addObserver(self, selector: #selector(didShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(didHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
    }

    func didShow()
    {
        isVisible = true
    }

    func didHide()
    {
        isVisible = false
    } 
}

You could also use

print(tbl_df(df), n=40)

or with the help of the pipe operator

df %>% tbl_df %>% print(n=40)

To print all rows specify tbl_df %>% print(n = Inf)

You could try putting the e-mails into a comma-delimited string ("[email protected], [email protected]"):

C#:

ArrayList arEmails = new ArrayList();
arEmails.Add("[email protected]");
arEmails.Add("[email protected]");
           
string strEmails = string.Join(", ", arEmails);

VB.NET if you're interested:

Dim arEmails As New ArrayList
arEmails.Add("[email protected]")
arEmails.Add("[email protected]")

Dim strEmails As String = String.Join(", ", arEmails)

This is a small program that will keep asking an input until required input is given.

we should keep the required number as a string, otherwise it may not work. input is taken as string by default

required_number = '18'

while True:
    number = input("Enter the number\n")
    if number == required_number:
        print ("GOT IT")
        break
    else:
        print ("Wrong number try again")

or you can use eval(input()) method

required_number = 18

while True:
    number = eval(input("Enter the number\n"))
    if number == required_number:
        print ("GOT IT")
        break
    else:
        print ("Wrong number try again")

Cascade will work when you delete something on table Courses. Any record on table BookCourses that has reference to table Courses will be deleted automatically.

But when you try to delete on table BookCourses only the table itself is affected and not on the Courses

follow-up question: why do you have CourseID on table Category?

Maybe you should restructure your schema into this,

CREATE TABLE Categories 
(
  Code CHAR(4) NOT NULL PRIMARY KEY,
  CategoryName VARCHAR(63) NOT NULL UNIQUE
);

CREATE TABLE Courses 
(
  CourseID INT NOT NULL PRIMARY KEY,
  BookID INT NOT NULL,
  CatCode CHAR(4) NOT NULL,
  CourseNum CHAR(3) NOT NULL,
  CourseSec CHAR(1) NOT NULL,
);

ALTER TABLE Courses
ADD FOREIGN KEY (CatCode)
REFERENCES Categories(Code)
ON DELETE CASCADE;

The shortcut format generally used for basic auth is http://username:[email protected]/path. You will also want to include the accept header in the request.

It is as easy as specifying a padding bottom the same size as the width in percent. So if you have a width of 50%, just use this example below

id or class{
    width: 50%;
    padding-bottom: 50%;
}

Here is a jsfiddle http://jsfiddle.net/kJL3u/2/

Edited version with responsive text: http://jsfiddle.net/kJL3u/394

You can use time.time() or time.clock() before and after the block you want to time.

import time

t0 = time.time()
code_block
t1 = time.time()

total = t1-t0

This method is not as exact as timeit (it does not average several runs) but it is straightforward.

time.time() (in Windows and Linux) and time.clock() (in Linux) are not precise enough for fast functions (you get total = 0). In this case or if you want to average the time elapsed by several runs, you have to manually call the function multiple times (As I think you already do in you example code and timeit does automatically when you set its number argument)

import time

def myfast():
   code

n = 10000
t0 = time.time()
for i in range(n): myfast()
t1 = time.time()

total_n = t1-t0

In Windows, as Corey stated in the comment, time.clock() has much higher precision (microsecond instead of second) and is preferred over time.time().

Adapting from the above answers, this works for Tomcat, but can be adapted for JBoss as well or any container:

sudo -u tomcat /opt/tomcat/bin/shutdown.sh
cd /opt/tomcat/webapps
sudo mkdir tmp; cd tmp
sudo jar -xvf ../myapp.war
#make edits...
sudo vi WEB-INF/classes/templates/fragments/header.html
sudo vi WEB-INF/classes/application.properties
#end of making edits
sudo jar -cvf myapp0.0.1.war *
sudo cp myapp0.0.1.war ..
cd ..
sudo chown tomcat:tomcat myapp0.0.1.war
sudo rm -rf tmp
sudo -u tomcat /opt/tomcat/bin/startup.sh

try table.Rows.add(row); after your for statement.

std::list doesn't provide any function to get element given an index. You may try to get it by writing some code, which I wouldn't recommend, because that would be inefficient if you frequently need to do so.

What you need is : std::vector. Use it as:

std::vector<Object> objects;
objects.push_back(myObject);

Object const & x = objects[0];    //index isn't checked
Object const & y = objects.at(0); //index is checked 

The best way Using dirname(). Because SERVER['DOCUMENT_ROOT'] not working all servers, and also return server running path.

$root = dirname( __FILE__ );

$root = __DIR__;

$filePath = realpath(dirname(__FILE__));

$rootPath = realpath($_SERVER['DOCUMENT_ROOT']);

$htmlPath = str_replace($root, '', $filePath);

radians = (degrees/360) * 2 * pi

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

You can also use the Get-Counter cmdlet (PowerShell 2.0):

Get-Counter '\Memory\Available MBytes'
Get-Counter '\Processor(_Total)\% Processor Time'

To get a list of memory counters:

Get-Counter -ListSet *memory* | Select-Object -ExpandProperty  Counter

You may want to use statement_timestamp(). This give the timestamp when the statement was executed. Whereas NOW() and CURRENT_TIMESTAMP give the timestamp when the transaction started.

@Hung Tran's answer works perfect. As an improvement, I would suggest not showing values that are 0. Say you have 5 elements and 2 of them are 0 and rest of them have values, the solution above will show 0 and 0%. It is better to filter that out with a not equal to 0 check!

          var val = dataset.data[i];
          var percent = String(Math.round(val/total*100)) + "%";

          if(val != 0) {
            ctx.fillText(dataset.data[i], model.x + x, model.y + y);
            // Display percent in another line, line break doesn't work for fillText
            ctx.fillText(percent, model.x + x, model.y + y + 15);
          }

Updated code below:

var data = {
    datasets: [{
        data: [

          var x = mid_radius * Math.cos(mid_angle);
          var y = mid_radius * Math.sin(mid_angle);

          ctx.fillStyle = '#fff';
          if (i == 3){ // Darker text color for lighter background

          }

          var val = dataset.data[i];
          var percent = String(Math.round(val/total*100)) + "%";

          if(val != 0) {
            ctx.fillText(dataset.data[i], model.x + x, model.y + y);
            // Display percent in another line, line break doesn't work for fillText
            ctx.fillText(percent, model.x + x, model.y + y + 15);
          }
        }
      });

When working with Spring boot 2.1.x this warning message appears when starting up the application.

As indicated here, maybe this problem didn't show up in earlier versions because the related property was set to true by default and now it is false:

https://github.com/spring-projects/spring-boot/issues/12007

In consequence, solving this is as simple as adding the following property to the spring application.property file.

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation = true

You should chain the replace() together instead of assigning the result and replacing again.

var strMessage1 = document.getElementById("element1") ;
strMessage1.innerHTML = strMessage1.innerHTML
                        .replace(/aaaaaa./g,'<a href=\"http://www.google.com/')
                        .replace(/.bbbbbb/g,'/world\">Helloworld</a>');

See DEMO.

Use this method:

public static string getBetween(string strSource, string strStart, string strEnd)
{
    if (strSource.Contains(strStart) && strSource.Contains(strEnd))
    {
        int Start, End;
        Start = strSource.IndexOf(strStart, 0) + strStart.Length;
        End = strSource.IndexOf(strEnd, Start);
        return strSource.Substring(Start, End - Start);
    }

    return "";
}

How to use it:

string source = "This is an example string and my data is here";
string data = getBetween(source, "my", "is");

There's a good article on the topic in the Python wiki: Why Lists Can't Be Dictionary Keys. As explained there:

What would go wrong if you tried to use lists as keys, with the hash as, say, their memory location?

It can be done without really breaking any of the requirements, but it leads to unexpected behavior. Lists are generally treated as if their value was derived from their content's values, for instance when checking (in-)equality. Many would - understandably - expect that you can use any list [1, 2] to get the same key, where you'd have to keep around exactly the same list object. But lookup by value breaks as soon as a list used as key is modified, and for lookup by identity requires you to keep around exactly the same list - which isn't requires for any other common list operation (at least none I can think of).

Other objects such as modules and object make a much bigger deal out of their object identity anyway (when was the last time you had two distinct module objects called sys?), and are compared by that anyway. Therefore, it's less surprising - or even expected - that they, when used as dict keys, compare by identity in that case as well.

$query->num_rows()

The number of rows returned by the query. Note: In this example, $query is the variable that the query result object is assigned to:

$query = $this->db->query('SELECT * FROM my_table');

echo $query->num_rows();

Yes, presumably it wants the path to the javadoc command line tool that comes with the JDK (in the bin directory, same as java and javac).

Eclipse should be able to find it automatically; are you perhaps running it on a JRE? That would explain the request.

The short version is that you cannot use variable-width patterns in lookbehinds using Python's re module. There is no way to change this:

>>> import re
>>> re.sub("(?<=foo)bar(?=baz)", "quux", "foobarbaz")
'fooquuxbaz'
>>> re.sub("(?<=fo+)bar(?=baz)", "quux", "foobarbaz")

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    re.sub("(?<=fo+)bar(?=baz)", "quux", string)
  File "C:\Development\Python25\lib\re.py", line 150, in sub
    return _compile(pattern, 0).sub(repl, string, count)
  File "C:\Development\Python25\lib\re.py", line 241, in _compile
    raise error, v # invalid expression
error: look-behind requires fixed-width pattern

This means that you'll need to work around it, the simplest solution being very similar to what you're doing now:

>>> re.sub("(fo+)bar(?=baz)", "\\1quux", "foobarbaz")
'fooquuxbaz'
>>>
>>> # If you need to turn this into a callable function:
>>> def replace(start, replace, end, replacement, search):
        return re.sub("(" + re.escape(start) + ")" + re.escape(replace) + "(?=" + re.escape + ")", "\\1" + re.escape(replacement), search)

This doesn't have the elegance of the lookbehind solution, but it's still a very clear, straightforward one-liner. And if you look at what an expert has to say on the matter (he's talking about JavaScript, which lacks lookbehinds entirely, but many of the principles are the same), you'll see that his simplest solution looks a lot like this one.

getline is storing the entire line at once, which is not what you want. A simple fix is to have three variables and use cin to get them all. C++ will parse automatically at the spaces.

#include <iostream>
using namespace std;

int main() {
    string a, b, c;
    cin >> a >> b >> c;
    //now you have your three words
    return 0;
}

I don't know what particular "operation" you're talking about, so I can't help you there, but if it's changing characters, read up on string and indices. The C++ documentation is great. As for using namespace std; versus std:: and other libraries, there's already been a lot said. Try these questions on StackOverflow to start.

So I was trying every method here, and this time none of them helped. My case was a grouped table view on iOS 9. I don't really know why and how I found out this one, but for me, setting the tableViewHeader with a UIView with at least 0.01 height worked out. CGRectZero didn't help, nothing really helped:

tableView.tableHeaderView = UIView(frame: CGRect(x: 0.0, y: 0.0, width: 0.0, height: 0.01))

You cannot really find the display resolution from a web page. There is a CSS Media Queries statement for it, but it is poorly implemented in most devices and browsers, if at all. However, you do not need to know the resolution of the display, because changing it causes the (pixel) width of the window to change, which can be detected using the methods others have described:

$(window).resize(function() {
  // This will execute whenever the window is resized
  $(window).height(); // New height
  $(window).width(); // New width
});

You can also use CSS Media Queries in browsers that support them to adapt your page's style to various display widths, but you should really be using em units and percentages and min-width and max-width in your CSS if you want a proper flexible layout. Gmail probably uses a combination of all these.

Delete the project named Servers (or Servers1, Servers2 which contains your server.xml), find it in Package Explorer(workspace)

Remove server from Eclipse : Go to Window > Preferences > Server > Runtime Environment, here remove the server your are using from eclipse and add it again(doing this will create a new Server project folder in Eclipse) ,

Remove server from Project : Also remove the server in your project(Build path > configuration path > Java Build path) and add again.

now you got a fresh Server project which will not have Multiple Context on its server.xml, only deleting duplicate path in server.xml solved the existing issue but still server dint start, by doing this Server started(Apache Tomcat v7) and worked normal

And I don't know whether this is good practice or not, I am a starter in programming.

Here below my code which works fine.

         const fs = require('fs');
         fs.unlink(__dirname+ '/test.txt', function (err) {            
              if (err) {                                                 
                  console.error(err);                                    
              }                                                          
             console.log('File has been Deleted');                           
          });                                                            

There's a C implementation here:

You don't have to do anything special, it should just be working.

When I have a fresh rails app with this controller:

class FooController < ApplicationController
  def index
    raise "error"
  end
end

and go to http://127.0.0.1:3000/foo/

I am seeing the exception with a stack trace.

You might not see the whole stacktrace in the console log because Rails (since 2.3) filters lines from the stack trace that come from the framework itself.

See config/initializers/backtrace_silencers.rb in your Rails project

While some suggestions have included tkinter and wxPython, the other part of the answer to your question is that you will also need to package it using something like py2app, pyinstaller, or py2exe (depending on the operating system). You mentioned the other machines do not have python, so this would be required in order to distribute the entire python environment with your app.

Also have a look at PySide or PyQt. They have a ton of tutorials everywhere and heavy documentation from Qt.

The real answer is you need to set the escape character to '\': SET ESCAPE ON

The problem may have occurred either because escaping was disabled, or the escape character was set to something other than '\'. The above statement will enable escaping and set it to '\'.

None of the other answers previously posted actually answer the original question. They all work around the problem but don't resolve it.

A better way to write the async function would be by returning a pending Promise from the start and then handling both rejections and resolutions within the callback of the promise, rather than just spitting out a rejected promise on error. Example:

async foo(id: string): Promise<A> {
    return new Promise(function(resolve, reject) {
        // execute some code here
        if (success) { // let's say this is a boolean value from line above
            return resolve(success);
        } else {
            return reject(error); // this can be anything, preferably an Error object to catch the stacktrace from this function
        }
    });
}

Then you just chain methods on the returned promise:

async function bar () {
    try {
        var result = await foo("someID")
        // use the result here
    } catch (error) {
        // handle error here
    }
}

bar()

Concerning n00b's comment: "I get the following warning: A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead"

I was getting the same error. In my case it was because I was trying to perform the column addition on a dataframe that was created like this:

df_b = df[['colA', 'colB', 'colC']]

instead of:

df_c = pd.DataFrame(df, columns=['colA', 'colB', 'colC'])

df_b is a copy of a slice from df
df_c is an new dataframe. So

df_c['colD'] = df['colA'] + df['colB']+ df['colC']

will add the columns and won't raise any warning. Same if .sum(axis=1) is used.

• SET NOCOUNT ON- It will show "Command(s) completed successfully".
• SET NOCOUNT OFF- it will show "(No. Of row(s) affected)".

Here is a complete example with output. psql (10.1, server 9.5.10).

You get 58, not some value less than 30.
Remove age() function, solved the problem that previous post mentioned.

drop table t;
create table t(
    d1 date
);

insert into t values(current_date - interval '58 day');

select d1
, current_timestamp - d1::timestamp date_diff
, date_part('day', current_timestamp - d1::timestamp)
from t;

     d1     |        date_diff        | date_part
------------+-------------------------+-----------
 2018-05-21 | 58 days 21:41:07.992731 |        58

Note that there is an unrelated issue in your code but that could bite you later: you should return res.json() or you will not catch any error occurring in JSON parsing or your own function processing data.

Back to your error: You cannot have a TypeError: failed to fetch with a successful request. You probably have another request (check your "network" panel to see all of them) that breaks and causes this error to be logged. Also, maybe check "Preserve log" to be sure the panel is not cleared by any indelicate redirection. Sometimes I happen to have a persistent "console" panel, and a cleared "network" panel that leads me to have error in console which is actually unrelated to the visible requests. You should check that.

Or you (but that would be vicious) actually have a hardcoded console.log('TypeError: failed to fetch') in your final .catch ;) and the error is in reality in your .then() but it's hard to believe.

this works for me on my Android 7.11 phone:

In terms of bytecode, in saves a LOAD_ATTR and replaces a CALL_FUNCTION with a COMPARE_OP.

>>> dis.dis(indict)
  2           0 LOAD_GLOBAL              0 (name)
              3 LOAD_GLOBAL              1 (d)
              6 COMPARE_OP               6 (in)
              9 POP_TOP             


>>> dis.dis(haskey)
  2           0 LOAD_GLOBAL              0 (d)
              3 LOAD_ATTR                1 (haskey)
              6 LOAD_GLOBAL              2 (name)
              9 CALL_FUNCTION            1
             12 POP_TOP             

My feelings are that in is much more readable and is to be preferred in every case that I can think of.

In terms of performance, the timing reflects the opcode

$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "'foo' in d"
 10000000 loops, best of 3: 0.11 usec per loop

$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "d.has_key('foo')"
  1000000 loops, best of 3: 0.205 usec per loop

in is almost twice as fast.
