A couple of things:

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

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

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

I faced same issue but now i am happy to resolve this issue.

1. npm i core-js
2. put this line into the first line of your index.js file. import core-js

I had this problem suddenly happening after trying to pull a dependency depending on sdk 28 (firebase crashlytics), but then decided to revert back the changes.

I tried automatic refactor Migrate to Androidx (which do half the job), added android.useAndroidX=true in gradle.properties at some points, and make the project work again.

But it was a lot of changes before a delivery. There was no way to have the project compile again with SDK 27. I git clean -fd, removed $HOME/.gradle, and kept seeing androidx in ./gradlew :app:dependencies

I ended up removing ~/.AndroidStudio3.5/ too (I'm on 3.5.3). This makes the project compile again, and I discovered the dark mode...

I got the same error. In my case, I was using a mapped drive to edit code off of a second computer, that computer was running linux. Not sure exactly why gulp-watch relies on operating system compatibility prior to install (I would assume it has to do with security purposes). Essentially the error is checking against your operating system and the operating system calling the node module, in my case the two operating systems were not the same so it threw it error. Which from the looks of your error is the same as mine.

The Error

Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

How I fixed it?

I logged into the linux computer directly and ran

npm install --save-dev <module-name>

Then went back into my coding environment and everything was fine after that.

Hope that helps!

open terminal and type command

sudo snap install postman

hit enter button if it asks for password enter and proceed it will install postman

If above solution doesn't work for you then you should install snap first to install it

sudo apt update
sudo apt install snapd

when snap is installed successfully then u can use its packages and follow my solution for postman

It works for me...

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

This is solution with FormGroup inside supports ( like here )

Tested on: Angular 4.3.6

get-form-validation-errors.ts

import { AbstractControl, FormGroup, ValidationErrors } from '@angular/forms';

export interface AllValidationErrors {
  control_name: string;
  error_name: string;
  error_value: any;
}

export interface FormGroupControls {
  [key: string]: AbstractControl;
}

export function getFormValidationErrors(controls: FormGroupControls): AllValidationErrors[] {
  let errors: AllValidationErrors[] = [];
  Object.keys(controls).forEach(key => {
    const control = controls[ key ];
    if (control instanceof FormGroup) {
      errors = errors.concat(getFormValidationErrors(control.controls));
    }
    const controlErrors: ValidationErrors = controls[ key ].errors;
    if (controlErrors !== null) {
      Object.keys(controlErrors).forEach(keyError => {
        errors.push({
          control_name: key,
          error_name: keyError,
          error_value: controlErrors[ keyError ]
        });
      });
    }
  });
  return errors;
}

Using example:

if (!this.formValid()) {
  const error: AllValidationErrors = getFormValidationErrors(this.regForm.controls).shift();
  if (error) {
    let text;
    switch (error.error_name) {
      case 'required': text = `${error.control_name} is required!`; break;
      case 'pattern': text = `${error.control_name} has wrong pattern!`; break;
      case 'email': text = `${error.control_name} has wrong email format!`; break;
      case 'minlength': text = `${error.control_name} has wrong length! Required length: ${error.error_value.requiredLength}`; break;
      case 'areEqual': text = `${error.control_name} must be equal!`; break;
      default: text = `${error.control_name}: ${error.error_name}: ${error.error_value}`;
    }
    this.error = text;
  }
  return;
}

You did not post the code generated by the compiler, so there' some guesswork here, but even without having seen it, one can say that this:

test rax, 1
jpe even

... has a 50% chance of mispredicting the branch, and that will come expensive.

The compiler almost certainly does both computations (which costs neglegibly more since the div/mod is quite long latency, so the multiply-add is "free") and follows up with a CMOV. Which, of course, has a zero percent chance of being mispredicted.

The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

column of first matrix = row of second matrix

and do not follow the below step

row of first matrix  = column of second matrix

it will throw an error

It is possible to upack without node installed using the following 7-Zip plugin:
http://www.tc4shell.com/en/7zip/asar/

Thanks @MayaPosch for mentioning that in this comment.

When you normalize a matrix using NORM_L1, you are dividing every pixel value by the sum of absolute values of all the pixels in the image. As a result, all pixel values become much less than 1 and you get a black image. Try NORM_MINMAX instead of NORM_L1.

I'm using latest TS and node (v2.6 and v8.9 respectively) and I can do:

let myMap = new Map<string, boolean>();
myMap.set("a", true);
for (let [k, v] of myMap) {
    console.log(k + "=" + v);
}

The error is because of the sql mode which can be strict mode as per latest MYSQL 5.7 documentation.

For more information read this.

Hope it helps.

There has already been good answers but I would like to mention one - You do NOT need to create a repository in advance before pushing it.

The problem for me was that I didn't set the correct username of the account I logged in to. But once the correct username is set before the image (e.g. YOURNAME/YOURIMAGE) via its tag, you can push it without creating a new repository in advance.

sudo docker tag IMAGE:VERSION USERNAME/IMAGE:VERSION
sudo docker push USERNAME/IMAGE:VERSION

This command worked fine for me:

RUN apt-get -y install python3-pip

this did it for me. you can vary the options for the output format to Base64.Default whatsoever.

// encode base64 from image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
encodedString = Base64.encodeToString(b, Base64.URL_SAFE | Base64.NO_WRAP);

Alternative Solution:

This answer of Thierry Templier is an alternative way to get around the problem.

After some questions with Thierry Templier, I came to the following working example that meets my expectations as an alternative to inheritance limitation mentioned in this question:

1 - Create custom decorator:

export function CustomComponent(annotation: any) {
  return function (target: Function) {
    var parentTarget = Object.getPrototypeOf(target.prototype).constructor;
    var parentAnnotations = Reflect.getMetadata('annotations', parentTarget);

    var parentAnnotation = parentAnnotations[0];
    Object.keys(parentAnnotation).forEach(key => {
      if (isPresent(parentAnnotation[key])) {
        // verify is annotation typeof function
        if(typeof annotation[key] === 'function'){
          annotation[key] = annotation[key].call(this, parentAnnotation[key]);
        }else if(
        // force override in annotation base
        !isPresent(annotation[key])
        ){
          annotation[key] = parentAnnotation[key];
        }
      }
    });

    var metadata = new Component(annotation);

    Reflect.defineMetadata('annotations', [ metadata ], target);
  }
}

2 - Base Component with @Component decorator:

@Component({
  // create seletor base for test override property
  selector: 'master',
  template: `
    <div>Test</div>
  `
})
export class AbstractComponent {

}

3 - Sub component with @CustomComponent decorator:

@CustomComponent({
  // override property annotation
  //selector: 'sub',
  selector: (parentSelector) => { return parentSelector + 'sub'}
})
export class SubComponent extends AbstractComponent {
  constructor() {
  }
}

Plunkr with complete example.

.forEach already has this ability:

const someArray = [9, 2, 5];
someArray.forEach((value, index) => {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
});

But if you want the abilities of for...of, then you can map the array to the index and value:

for (const { index, value } of someArray.map((value, index) => ({ index, value }))) {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
}

That's a little long, so it may help to put it in a reusable function:

function toEntries<T>(a: T[]) {
    return a.map((value, index) => [index, value] as const);
}

for (const [index, value] of toEntries(someArray)) {
    // ..etc..
}

Iterable Version

This will work when targeting ES3 or ES5 if you compile with the --downlevelIteration compiler option.

function* toEntries<T>(values: T[] | IterableIterator<T>) {
    let index = 0;
    for (const value of values) {
        yield [index, value] as const;
        index++;
    }
}

Array.prototype.entries() - ES6+

If you are able to target ES6+ environments then you can use the .entries() method as outlined in Arnavion's answer.

The default parser can parse your input. So you don't need a custom formatter and

String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);

works as expected.

In my case, I'm using an AppBarLayout with a CollapsingToolbarLayout and the menu was always being scrolled out of the screen, I solved my problem by switching android:actionLayout in menu's XML to the toolbar's id. I hope it can help people in the same situation!

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

The first part of your question is a duplicate of Why do I get a JsonReaderException with this code?, but the most relevant part from that (my) answer is this:

[A] JObject isn't the elementary base type of everything in JSON.net, but JToken is. So even though you could say,

object i = new int[0];

in C#, you can't say,

JObject i = JObject.Parse("[0, 0, 0]");

in JSON.net.

What you want is JArray.Parse, which will accept the array you're passing it (denoted by the opening [ in your API response). This is what the "StartArray" in the error message is telling you.

As for what happened when you used JArray, you're using arr instead of obj:

var rcvdData = JsonConvert.DeserializeObject<LocationData>(arr /* <-- Here */.ToString(), settings);

Swap that, and I believe it should work.

Although I'd be tempted to deserialize arr directly as an IEnumerable<LocationData>, which would save some code and effort of looping through the array. If you aren't going to use the parsed version separately, it's best to avoid it.

With angular 4 you can fix this issue by updating app.module.ts file as follows:

Add import statement at the top as below:

import {APP_BASE_HREF} from '@angular/common';

And add below line inside @NgModule

providers: [{provide: APP_BASE_HREF, useValue: '/my/app'}]

Reff: https://angular.io/api/common/APP_BASE_HREF

Run these commands in a terminal window (note: DON'T replace the $USER part... thats a linux command to get your user!):

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/lib/node_modules
sudo chown -R $USER /usr/local/lib/node_modules

Just access the first item of the list/array, using the index access and the index 0:

>>> list_ = [4]
>>> list_[0]
4
>>> array_ = np.array([4])
>>> array_[0]
4

This will be an int since that was what you inserted in the first place. If you need it to be a float for some reason, you can call float() on it then:

>>> float(list_[0])
4.0

Answer given by kennyut/Kistian works very well but to get exact RDD like output when RDD consist of list of attributes e.g. [1,2,3,4] we can use flatmap command as below,

rdd = df.rdd.flatMap(list)
or 
rdd = df.rdd.flatmap(lambda x: list(x))

In my case I had inherited from the IdentityDbContext correctly (with my own custom types and key defined) but had inadvertantly removed the call to the base class's OnModelCreating:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder); // I had removed this
    /// Rest of on model creating here.
}

Which then fixed up my missing indexes from the identity classes and I could then generate migrations and enable migrations appropriately.

You're getting HTTP 415 "The request entity's media type 'multipart/form-data' is not supported for this resource." because you haven't mention the correct content type in your request.

The warning message

[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

means that you somehow passed -P pom.xml to Maven which means "there is a profile called pom.xml; find it and activate it". Check your environment and your settings.xml for this flag and also look at all <profile> elements inside the various XML files.

Usually, mvn help:effective-pom is also useful to see what the real POM would look like.

Now the error means that you tried to configure Maven to build Java 8 code but you're not using a Java 8 runtime. Solutions:

1. Install Java 8
2. Make sure Maven uses Java 8 if you have it installed. JAVA_HOME is your friend
3. Configure the Java compiler in your pom.xml to a Java version which you actually have.

Nowadays (2016) in Chrome Dev Tools console, you can quickly execute this function below to show all event listeners that have been attached to an element.

getEventListeners(document.querySelector('your-element-selector'));

Another way you can achieve the desired effect is to use this Material Search View library. It handles search history automatically and it's possible to provide search suggestions to the view as well.

Sample: (It's shown in Portuguese, but it also works in english and italian).

Setup

Before you can use this lib, you have to implement a class named MsvAuthority inside the br.com.mauker package on your app module, and it should have a public static String variable called CONTENT_AUTHORITY. Give it the value you want and don't forget to add the same name on your manifest file. The lib will use this file to set the Content Provider authority.

Example:

MsvAuthority.java

package br.com.mauker;

public class MsvAuthority {
    public static final String CONTENT_AUTHORITY = "br.com.mauker.materialsearchview.searchhistorydatabase";
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>

    <application ... >
        <provider
        android:name="br.com.mauker.materialsearchview.db.HistoryProvider"
        android:authorities="br.com.mauker.materialsearchview.searchhistorydatabase"
        android:exported="false"
        android:protectionLevel="signature"
        android:syncable="true"/>
    </application>

</manifest>

Usage

To use it, add the dependency:

compile 'br.com.mauker.materialsearchview:materialsearchview:1.2.0'

And then, on your Activity layout file, add the following:

<br.com.mauker.materialsearchview.MaterialSearchView
    android:id="@+id/search_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

After that, you'll just need to get the MaterialSearchView reference by using getViewById(), and open it up or close it using MaterialSearchView#openSearch() and MaterialSearchView#closeSearch().

P.S.: It's possible to open and close the view not only from the Toolbar. You can use the openSearch() method from basically any Button, such as a Floating Action Button.

// Inside onCreate()
MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
Button bt = (Button) findViewById(R.id.button);

bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            searchView.openSearch();
        }
    });

You can also close the view using the back button, doing the following:

@Override
public void onBackPressed() {
    if (searchView.isOpen()) {
        // Close the search on the back button press.
        searchView.closeSearch();
    } else {
        super.onBackPressed();
    }
}

For more information on how to use the lib, check the github page.

If you have a list of lists, you only needed to use ...

import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.

Add this line at the top:

"xmlns:app="http://schemas.android.com/apk/res-auto"

and then use:

app:showasaction="ifroom"

Simple:

<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0" />

Cheers!

Try this mate, you can chuck it in the body like so...

    [HttpPost]
    [Route("~/API/ChangeTheNameIfNeeded")]
    public bool SampleCall([FromBody]JObject data)
    {
        var firstName = data["firstName"].ToString();
        var lastName= data["lastName"].ToString();
        var email = data["email"].ToString();
        var obj= data["toLastName"].ToObject<SomeObject>();

        return _someService.DoYourBiz(firstName, lastName, email, obj);
    }

Instead of handcranking your models try using something like the Json2csharp.com website. Paste In an example JSON response, the fuller the better and then pull in the resultant generated classes. This, at least, takes away some moving parts, will get you the shape of the JSON in csharp giving the serialiser an easier time and you shouldnt have to add attributes.

Just get it working and then make amendments to your class names, to conform to your naming conventions, and add in attributes later.

EDIT: Ok after a little messing around I have successfully deserialised the result into a List of Job (I used Json2csharp.com to create the class for me)

public class Job
{
        public string id { get; set; }
        public string position_title { get; set; }
        public string organization_name { get; set; }
        public string rate_interval_code { get; set; }
        public int minimum { get; set; }
        public int maximum { get; set; }
        public string start_date { get; set; }
        public string end_date { get; set; }
        public List<string> locations { get; set; }
        public string url { get; set; }
}

And an edit to your code:

        List<Job> model = null;
        var client = new HttpClient();
        var task = client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs")
          .ContinueWith((taskwithresponse) =>
          {
              var response = taskwithresponse.Result;
              var jsonString = response.Content.ReadAsStringAsync();
              jsonString.Wait();
              model = JsonConvert.DeserializeObject<List<Job>>(jsonString.Result);

          });
        task.Wait();

This means you can get rid of your containing object. Its worth noting that this isn't a Task related issue but rather a deserialisation issue.

EDIT 2:

There is a way to take a JSON object and generate classes in Visual Studio. Simply copy the JSON of choice and then Edit> Paste Special > Paste JSON as Classes. A whole page is devoted to this here:

In my case, I copied the project and pasted it as another project. The Global.asax file contains the wrong file name, so I just change

<%@ Application Codebehind="Global.asax.cs" 
    Inherits="WrongAppname.MvcApplication" Language="C#" %>

to

<%@ Application Codebehind="Global.asax.cs" 
    Inherits="RightAppName.MvcApplication" Language="C#" %>

For the sake of other developers who finds this question and need another solution that fits not only for unit-tests:

I've found this on a blog (not my solution! Credit to the blog's owner).

TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;

SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
        .loadTrustMaterial(null, acceptingTrustStrategy)
        .build();

SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

CloseableHttpClient httpClient = HttpClients.custom()
        .setSSLSocketFactory(csf)
        .build();

HttpComponentsClientHttpRequestFactory requestFactory =
        new HttpComponentsClientHttpRequestFactory();

requestFactory.setHttpClient(httpClient);

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

I did it this way (you need to add a class text to <td> and put the text between a <span>:

HTML

<td class="text"><span>looooooong teeeeeeeeext</span></td>

SASS

.table td.text {
    max-width: 177px;
    span {
        white-space: nowrap;
        overflow: hidden;
        text-overflow: ellipsis;
        display: inline-block;
        max-width: 100%;
    }
}

CSS equivalent

.table td.text {
    max-width: 177px;
}
.table td.text span {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    display: inline-block;
    max-width: 100%;
}

And it will still be mobile responsive (forget it with layout=fixed) and will keep the original behaviour.

PS: Of course 177px is a custom size (put whatever you need).

Please check if you are were passing method as POST instead as GET. if so you will get same error as a you posted above.

$http({               
 method: 'GET',

The request entity's media type 'text/plain' is not supported for this resource.

You JSON doesn't match your struct fields: E.g. "district" in JSON and "District" as the field.

Also: Your Item is a slice type but your JSON is a dict value. Do not mix this up. Slices decode from arrays.

If anyone else is having a nullptr on the searchview variable, I found out that the item setup is a tiny bit different:

old:

android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView"

new:

app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="androidx.appcompat.widget.SearchView"

pre-android x:

app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"

Here's my attempt at a comprehensive answer from the dplyr perspective, following the broad outline of Arun's answer (but somewhat rearranged based on differing priorities).

Syntax

There is some subjectivity to syntax, but I stand by my statement that the concision of data.table makes it harder to learn and harder to read. This is partly because dplyr is solving a much easier problem!

One really important thing that dplyr does for you is that it constrains your options. I claim that most single table problems can be solved with just five key verbs filter, select, mutate, arrange and summarise, along with a "by group" adverb. That constraint is a big help when you're learning data manipulation, because it helps order your thinking about the problem. In dplyr, each of these verbs is mapped to a single function. Each function does one job, and is easy to understand in isolation.

You create complexity by piping these simple operations together with %>%. Here's an example from one of the posts Arun linked to:

diamonds %>%
  filter(cut != "Fair") %>%
  group_by(cut) %>%
  summarize(
    AvgPrice = mean(price),
    MedianPrice = as.numeric(median(price)),
    Count = n()
  ) %>%
  arrange(desc(Count))

Even if you've never seen dplyr before (or even R!), you can still get the gist of what's happening because the functions are all English verbs. The disadvantage of English verbs is that they require more typing than [, but I think that can be largely mitigated by better autocomplete.

Here's the equivalent data.table code:

diamondsDT <- data.table(diamonds)
diamondsDT[
  cut != "Fair", 
  .(AvgPrice = mean(price),
    MedianPrice = as.numeric(median(price)),
    Count = .N
  ), 
  by = cut
][ 
  order(-Count) 
]

It's harder to follow this code unless you're already familiar with data.table. (I also couldn't figure out how to indent the repeated [ in a way that looks good to my eye). Personally, when I look at code I wrote 6 months ago, it's like looking at a code written by a stranger, so I've come to prefer straightforward, if verbose, code.

Two other minor factors that I think slightly decrease readability:

• Since almost every data table operation uses [ you need additional context to figure out what's happening. For example, is x[y] joining two data tables or extracting columns from a data frame? This is only a small issue, because in well-written code the variable names should suggest what's happening.

• I like that group_by() is a separate operation in dplyr. It fundamentally changes the computation so I think should be obvious when skimming the code, and it's easier to spot group_by() than the by argument to [.data.table.

I also like that the the pipe isn't just limited to just one package. You can start by tidying your data with tidyr, and finish up with a plot in ggvis. And you're not limited to the packages that I write - anyone can write a function that forms a seamless part of a data manipulation pipe. In fact, I rather prefer the previous data.table code rewritten with %>%:

diamonds %>% 
  data.table() %>% 
  .[cut != "Fair", 
    .(AvgPrice = mean(price),
      MedianPrice = as.numeric(median(price)),
      Count = .N
    ), 
    by = cut
  ] %>% 
  .[order(-Count)]

And the idea of piping with %>% is not limited to just data frames and is easily generalised to other contexts: interactive web graphics, web scraping, gists, run-time contracts, ...)

Memory and performance

I've lumped these together, because, to me, they're not that important. Most R users work with well under 1 million rows of data, and dplyr is sufficiently fast enough for that size of data that you're not aware of processing time. We optimise dplyr for expressiveness on medium data; feel free to use data.table for raw speed on bigger data.

The flexibility of dplyr also means that you can easily tweak performance characteristics using the same syntax. If the performance of dplyr with the data frame backend is not good enough for you, you can use the data.table backend (albeit with a somewhat restricted set of functionality). If the data you're working with doesn't fit in memory, then you can use a database backend.

All that said, dplyr performance will get better in the long-term. We'll definitely implement some of the great ideas of data.table like radix ordering and using the same index for joins & filters. We're also working on parallelisation so we can take advantage of multiple cores.

Features

A few things that we're planning to work on in 2015:

• the readr package, to make it easy to get files off disk and in to memory, analogous to fread().

• More flexible joins, including support for non-equi-joins.

• More flexible grouping like bootstrap samples, rollups and more

I'm also investing time into improving R's database connectors, the ability to talk to web apis, and making it easier to scrape html pages.

One of the variables has not been given any value, thus it is a NoneType. You'll have to look into why this is, it's probably a simple logic error on your part.

This following code should extract face in images and save faces on disk

def detect(image):
    image_faces = []
    bitmap = cv.fromarray(image)
    faces = cv.HaarDetectObjects(bitmap, cascade, cv.CreateMemStorage(0))
    if faces:
        for (x,y,w,h),n in faces:
            image_faces.append(image[y:(y+h), x:(x+w)])
            #cv2.rectangle(image,(x,y),(x+w,y+h),(255,255,255),3)
    return image_faces

if __name__ == "__main__":
    cam = cv2.VideoCapture(0)
    while 1:
        _,frame =cam.read()
        image_faces = []
        image_faces = detect(frame)
        for i, face in enumerate(image_faces):
            cv2.imwrite("face-" + str(i) + ".jpg", face)

        #cv2.imshow("features", frame)
        if cv2.waitKey(1) == 0x1b: # ESC
            print 'ESC pressed. Exiting ...'
            break

GlobalConfiguration class is part of Microsoft.AspNet.WebApi.WebHost nuget package...Have you upgraded this package to Web API 2?

All is right but in my case i have two class like this

namespace WebAPI.Model
{
   public class ProductsModel
{ 
        [Table("products")]
        public class Products
        {
            [Key]
            public int slno { get; set; }

            public int productId { get; set; }
            public string ProductName { get; set; }

            public int Price { get; set; }
}
        }
    }

After deleting the upper class it works fine for me.

HTML:
 <div id="container"></div>   
JS:


$('#search').click(function() {
    $.ajax({
        type: 'POST',
        url: 'cityResults.htm',
        data: $('#cityDetails').serialize(),
        dataType:"json", //to parse string into JSON object,
        success: function(data){ 

                var len = data.length;
                var txt = "";
                if(len > 0){
                    for(var i=0;i<len;i++){

                            txt = "<tr><td>"+data[i].city+"</td><td>"+data[i].cStatus+"</td></tr>";
                            $("#container").append(txt);
                    }



        },
        error: function(jqXHR, textStatus, errorThrown){
            alert('error: ' + textStatus + ': ' + errorThrown);
        }
    });
    return false;
});

Please check this code, it works fine for me.

$data = array('shopid'=>3,'version'=> 1,'value=>1');  //here $data is dummy varaible

error_log(print_r($data,true), 3, $_SERVER['DOCUMENT_ROOT']."/your-file-name.log");

//In $data we can mention the error messege and create the log

I resolved this problem this way:

In onCreateOptionsMenu:

this.menu = menu;
this.menu.add("calendar");
ImageView imageView = new ImageView(getActivity());
imageView.setMinimumHeight(128);
imageView.setMinimumWidth(128);
imageView.setImageDrawable(yourDrawable);
MenuItem item = this.menu.getItem(0);
item.setActionView(imageView);

in onOptionsItemSelected:

if (item.getOrder() == 0) {
    //TODO
    return true;
}

Swift 5 Very Easy way

//MARK:- First you need to encoded your arr or what ever object you want to save in UserDefaults

Here is a solution with an stdout redirection:

def elevate():
    import ctypes, win32com.shell.shell, win32event, win32process
    outpath = r'%s\%s.out' % (os.environ["TEMP"], os.path.basename(__file__))
    if ctypes.windll.shell32.IsUserAnAdmin():
        if os.path.isfile(outpath):
            sys.stderr = sys.stdout = open(outpath, 'w', 0)
        return
    with open(outpath, 'w+', 0) as outfile:
        hProc = win32com.shell.shell.ShellExecuteEx(lpFile=sys.executable, \
            lpVerb='runas', lpParameters=' '.join(sys.argv), fMask=64, nShow=0)['hProcess']
        while True:
            hr = win32event.WaitForSingleObject(hProc, 40)
            while True:
                line = outfile.readline()
                if not line: break
                sys.stdout.write(line)
            if hr != 0x102: break
    os.remove(outpath)
    sys.stderr = ''
    sys.exit(win32process.GetExitCodeProcess(hProc))

if __name__ == '__main__':
    elevate()

My simple trick to change background color and color of the text in Popup Menu / Option Menu

<style name="CustomActionBarTheme"
       parent="@android:style/Theme.Holo">
    <item name="android:popupMenuStyle">@style/MyPopupMenu</item>
    <item name="android:itemTextAppearance">@style/TextAppearance</item>
</style>
<!-- Popup Menu Background Color styles -->
<style name="MyPopupMenu" 
       parent="@android:style/Widget.Holo.ListPopupWindow">
    <item name="android:popupBackground">@color/Your_color_for_background</item> 
</style>
<!-- Popup Menu Text Color styles -->
<style name="TextAppearance">
    <item name="android:textColor">@color/Your_color_for_text</item>
</style>

One possible reason this might happen is that the Application Pool in IIS is configured to run under some custom account and this account either doesn't exist or a wrong password has been provided, or the password has been changed. Look at the advanced properties of the Application Pool in IIS for which account it uses.

Also the Event Log might contain more information as to why the Application Pool is stopping immediately on the first request.

SO thread 'Multiply two arrays element wise, where one of the arrays has arrays as elements' has an example of constructing an array from arrays. If the subarrays are the same size, numpy makes a 2d array. But if they differ in length, it makes an array with dtype=object, and the subarrays retain their identity.

Following that, you could do something like this:

In [5]: result=np.array([np.zeros((1)),np.zeros((2))])

In [6]: result
Out[6]: array([array([ 0.]), array([ 0.,  0.])], dtype=object)

In [7]: np.append([result[0]],[1,2])
Out[7]: array([ 0.,  1.,  2.])

In [8]: result[0]
Out[8]: array([ 0.])

In [9]: result[0]=np.append([result[0]],[1,2])

In [10]: result
Out[10]: array([array([ 0.,  1.,  2.]), array([ 0.,  0.])], dtype=object)

However, I don't offhand see what advantages this has over a pure Python list or lists. It does not work like a 2d array. For example I have to use result[0][1], not result[0,1]. If the subarrays are all the same length, I have to use np.array(result.tolist()) to produce a 2d array.

Install-Package Microsoft.AspNet.WebApi -Version 5.0.0

It works fine in my case....thnkz

Well.. for me it was Telerik JustMock Q3 2013 (13.3.1015.0) that caused the problem. Uninstalled it from VS 2013 and the problem has gone..

see also ASP.NET-MVC4 Code Not Running and http://feedback.telerik.com/Project/105/Feedback/Details/63749-unable-to-debug-asp-net-projects-with-q3-2013

One lost day and many new white hairs... Curse on you Telerik guys! ;)

or you can use this thing

$arr = [1,2,3];
$obj = json_decode(json_encode($arr));
print_r($obj);

This simple problem can cause a real headache!

I can see your controller EDIT (PUT) method expects 2 parameters: a) an int id, and b) a department object.

It is the default code when you generate this from VS > add controller with read/write options. However, you have to remember to consume this service using the two parameters, otherwise you will get the error 405.

In my case, I did not need the id parameter for PUT, so I just dropped it from the header... after a few hours of not noticing it there! If you keep it there, then the name must also be retained as id, unless you go on to make necessary changes to your configurations.

The easiest solution would be to use Wireshark and trace the HTTP tcp flow.

I'd suggest using a pseudo element in place of the overlay element. Because pseudo elements can't be added on enclosed img elements, you would still need to wrap the img element though.

LIVE EXAMPLE HERE -- EXAMPLE WITH TEXT

<div class="image">
    <img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

As for the CSS, set optional dimensions on the .image element, and relatively position it. If you are aiming for a responsive image, just omit the dimensions and this will still work (example). It's just worth noting that the dimensions must be on the parent element as opposed to the img element itself, see.

.image {
    position: relative;
    width: 400px;
    height: 400px;
}

Give the child img element a width of 100% of the parent and add vertical-align:top to fix the default baseline alignment issues.

.image img {
    width: 100%;
    vertical-align: top;
}

As for the pseudo element, set a content value and absolutely position it relative to the .image element. A width/height of 100% will ensure that this works with varying img dimensions. If you want to transition the element, set an opacity of 0 and add the transition properties/values.

.image:after {
    content: '\A';
    position: absolute;
    width: 100%; height:100%;
    top:0; left:0;
    background:rgba(0,0,0,0.6);
    opacity: 0;
    transition: all 1s;
    -webkit-transition: all 1s;
}

Use an opacity of 1 when hovering over the pseudo element in order to facilitate the transition:

.image:hover:after {
    opacity: 1;
}

END RESULT HERE

If you want to add text on hover:

For the simplest approach, just add the text as the pseudo element's content value:

EXAMPLE HERE

.image:after {
    content: 'Here is some text..';
    color: #fff;

    /* Other styling.. */
}

That should work in most instances; however, if you have more than one img element, you might not want the same text to appear on hover. You could therefore set the text in a data-* attribute and therefore have unique text for every img element.

EXAMPLE HERE

.image:after {
    content: attr(data-content);
    color: #fff;
}

With a content value of attr(data-content), the pseudo element adds the text from the .image element's data-content attribute:

<div data-content="Text added on hover" class="image">
    <img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

You can add some styling and do something like this:

EXAMPLE HERE

In the above example, the :after pseudo element serves as the black overlay, while the :before pseudo element is the caption/text. Since the elements are independent of each other, you can use separate styling for more optimal positioning.

.image:after, .image:before {
    position: absolute;
    opacity: 0;
    transition: all 0.5s;
    -webkit-transition: all 0.5s;
}
.image:after {
    content: '\A';
    width: 100%; height:100%;
    top: 0; left:0;
    background:rgba(0,0,0,0.6);
}
.image:before {
    content: attr(data-content);
    width: 100%;
    color: #fff;
    z-index: 1;
    bottom: 0;
    padding: 4px 10px;
    text-align: center;
    background: #f00;
    box-sizing: border-box;
    -moz-box-sizing:border-box;
}
.image:hover:after, .image:hover:before {
    opacity: 1;
}

Try using this code to make it responsive

iframe, object, embed {
    max-width: 100%;
}

While in Java it's indeed a bad practice to use exceptions for flow control (mainly because exceptions force the JVM to gather resources (more here)), in Python you have two important principles: duck typing and EAFP. This basically means that you are encouraged to try using an object the way you think it would work, and handle when things are not like that.

In summary, the only problem would be your code getting too much indented. If you feel like it, try to simplify some of the nestings, like lqc suggested in the suggested answer above.

[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("Age")]
public int required { get; set; }
[JsonProperty("Location")]
public string type { get; set; }

and Remove a "{"..,

strFieldString = strFieldString.Remove(0, strFieldString.IndexOf('{'));

DeserializeObject..,

   optionsItem objActualField = JsonConvert.DeserializeObject<optionsItem(strFieldString);

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

for me , using export PYTHONIOENCODING=UTF-8 before executing python command worked .

Your question is a little unclear...as the part that you indicate you want to bold in Excel is a DataGridView in the import from word method. Do you maybe want to bold the first row in the excel document?

using xl = Microsoft.Office.Interop.Excel;

xl.Range rng = (xl.Range)xlWorkSheet.Rows[0];
rng.Font.Bold = true;

Simple as that!

HTH, Z

this states that Account.deposit(Double.MAX_VALUE); it is setting deposit value to MAX value of Double dataType.to procced for running tests.

The shortest solution that will work with any Java version:

<profiles>
    <profile>
        <id>disable-java8-doclint</id>
        <activation>
            <jdk>[1.8,)</jdk>
        </activation>
        <properties>
            <additionalparam>-Xdoclint:none</additionalparam>
        </properties>
    </profile>
</profiles>

Just add that to your POM and you're good to go.

This is basically @ankon's answer plus @zapp's answer.

For maven-javadoc-plugin 3.0.0 users:

Replace

<additionalparam>-Xdoclint:none</additionalparam>

by

<doclint>none</doclint>

Modify onClick() as follows:

@Override
public void onClick(View v) {
    if(v == btn) {
        canvas=sv.getHolder().lockCanvas();
        if(canvas!=null) {
            canvas.drawBitmap(bitmap, 100, 100, null);
            sv.getHolder().unlockCanvasAndPost(canvas);
        }
    } else if(v == btn1) {
        saveBitmapToInternalStorage(bitmap);
    }
}

There are several ways to enforce that btn must be pressed before btn1 so that the bitmap is painted before you attempt to save it.

I suggest that you initially disable btn1, and that you enable it when btn is clicked, like this:

if(v == btn) {
    ...
    btn1.setEnabled(true);
}

Even i had two forms one for desktop view and other for mobile view , Removed one formed worked for me . I dint knew asp.page should have only one form.

Create a Route attribute for your method.

example

        [Route("api/Get")]
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

You can call like these http://localhost/api/Get

There is an issue with iOS not registering click/touch events bound to elements added after DOM loads.

While PPK has this advice: http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

I've found this the easy fix, simply add this to the css:

cursor: pointer;

You could use crypto-js.

I would also recommend using SHA256, rather than MD5.

To install crypto-js via NPM:

npm install crypto-js

Alternatively you can use a CDN and reference the JS file.

Then to display a MD5 and SHA256 hash, you can do the following:

<script type="text/javascript">
    var md5Hash = CryptoJS.MD5("Test");
    var sha256Hash = CryptoJS.SHA256("Test1");

    console.log(md5Hash.toString());
    console.log(sha256Hash.toString());
</script>

Working example located here, JSFiddle

There are also other JS functions that will generate an MD5 hash, outlined below.

http://www.myersdaily.org/joseph/javascript/md5-text.html

http://pajhome.org.uk/crypt/md5/md5.html

function md5cycle(x, k) {

Another working JS Fiddle here

Try this

SELECT * 
FROM xxx 
WHERE dates BETWEEN STR_TO_DATE('10/10/2012', '%m/%d/%Y') 
  AND STR_TO_DATE('10/12/2012', '%m/%d/%Y')  ;

or

SELECT * 
FROM xxx 
WHERE STR_TO_DATE(dates , '%m/%d/%Y') BETWEEN STR_TO_DATE('10/10/2012', '%m/%d/%Y') 
  AND STR_TO_DATE('10/12/2012', '%m/%d/%Y')  ;

Where have you specified the mapping code (CreateMap)? Reference: Where do I configure AutoMapper?

If you're using the static Mapper method, configuration should only happen once per AppDomain. That means the best place to put the configuration code is in application startup, such as the Global.asax file for ASP.NET applications.

If the configuration isn't registered before calling the Map method, you will receive Missing type map configuration or unsupported mapping.

• if you unable to find assembly reference from when (Right click on reference ->add required assembly)

try this Package manager console
Install-Package System.Net.Http.Formatting.Extension -Version 5.2.3 and then add by using add reference .

You should be able to simply let PIL get the filetype from extension, i.e. use:

j.save("C:/Users/User/Desktop/mesh_trans.bmp")

The difference can be demonstrated by this example:

1. generate a matrix

   >>> A = numpy.matrix(numpy.ones((3,3)))
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 1.,  1.,  1.]])
   

2. use numpy.array to modify A. Doesn't work because you are modifying a copy

   >>> numpy.array(A)[2]=2
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 1.,  1.,  1.]])
   

3. use numpy.asarray to modify A. It worked because you are modifying A itself

   >>> numpy.asarray(A)[2]=2
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 2.,  2.,  2.]])
   

Hope this helps!

Implements Parcelable and send arraylist as putParcelableArrayListExtra and get it from next activity getParcelableArrayListExtra

example:

Implement parcelable on your custom class -(Alt +enter) Implement its methods

public class Model implements Parcelable {

private String Id;

public Model() {

}

protected Model(Parcel in) {
    Id= in.readString();       
}

public static final Creator<Model> CREATOR = new Creator<Model>() {
    @Override
    public ModelcreateFromParcel(Parcel in) {
        return new Model(in);
    }

    @Override
    public Model[] newArray(int size) {
        return new Model[size];
    }
};

public String getId() {
    return Id;
}

public void setId(String Id) {
    this.Id = Id;
}


@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(Id);
}
}

Pass class object from activity 1

 Intent intent = new Intent(Activity1.this, Activity2.class);
            intent.putParcelableArrayListExtra("model", modelArrayList);
            startActivity(intent);

Get extra from Activity2

if (getIntent().hasExtra("model")) {
        Intent intent = getIntent();
        cartArrayList = intent.getParcelableArrayListExtra("model");

    } 

To differentiate the routes, try adding a constraint that id must be numeric:

RouteTable.Routes.MapHttpRoute(
         name: "DefaultApi",
         routeTemplate: "api/{controller}/{id}",
         constraints: new { id = @"\d+" }, // Only matches if "id" is one or more digits.
         defaults: new { id = System.Web.Http.RouteParameter.Optional }
         );  

I highly recommend you use the tobytes function of the Image object. After some timing checks this is much more efficient.

def jpg_image_to_array(image_path):
  """
  Loads JPEG image into 3D Numpy array of shape 
  (width, height, channels)
  """
  with Image.open(image_path) as image:         
    im_arr = np.fromstring(image.tobytes(), dtype=np.uint8)
    im_arr = im_arr.reshape((image.size[1], image.size[0], 3))                                   
  return im_arr

The timings I ran on my laptop show

In [76]: %timeit np.fromstring(im.tobytes(), dtype=np.uint8)
1000 loops, best of 3: 230 µs per loop

In [77]: %timeit np.array(im.getdata(), dtype=np.uint8)
10 loops, best of 3: 114 ms per loop

This error started happening to me out of nowhere last week, affecting the existing web sites on my machine. I had no luck with it trying any of the suggestions here. Eventually I removed WebDAV from IIS completely (Windows Features -> Internet Information Services -> World Wide Web Services -> Common HTTP Features -> WebDAV Publishing). I did an IIS reset after this for good measure, and my error was finally resolved.

I can only guess that a Windows update started the issue, but I can't be sure.

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

I ran into this issue when the number of <th> tags in the '' did not match the number of in the <tfoot> section

<thead>
    <tr>
        <th></th>
        <th>Subject Areas</th>
        <th></th>
        <th>Option(s)</th>
    <tr>
</thead>

<tbody></tbody>

<tfoot>
    <tr>
        <th></th>
        <th></th>
        <th></th>
        <th></th>
    </tr>
</tfoot>

Try using ReadAsStringAsync() instead.

 var foo = resp.Content.ReadAsStringAsync().Result;

The reason why it ReadAsAsync<string>() doesn't work is because ReadAsAsync<> will try to use one of the default MediaTypeFormatter (i.e. JsonMediaTypeFormatter, XmlMediaTypeFormatter, ...) to read the content with content-type of text/plain. However, none of the default formatter can read the text/plain (they can only read application/json, application/xml, etc).

By using ReadAsStringAsync(), the content will be read as string regardless of the content-type.

Interaction of Javascript and PHP

We all grew up knowing that Javascript ran on the Client Side (ie the browser) and PHP was a server side tool (ie the Server side). CLEARLY the two just cant interact.

But -- good news; it can be made to work and here's how.

The objective is to get some dynamic info (say server configuration items) from the server into the Javascript environment so it can be used when needed - - typically this implies DHTML modification to the presentation.

First, to clarify the DHTML usage I'll cite this DHTML example:

<script type="text/javascript">

function updateContent() {
 var frameObj = document.getElementById("frameContent");
 var y = (frameObj.contentWindow || frameObj.contentDocument);

 if (y.document) y = y.document;
 y.body.style.backgroundColor="red";  // demonstration of failure to alter the display

 // create a default, simplistic alteration usinga fixed string.
 var textMsg = 'Say good night Gracy';

 y.write(textMsg);

 y.body.style.backgroundColor="#00ee00";  // visual confirmation that the updateContent() was effective

}
</script>

Assuming we have an html file with the ID="frameContent" somewhere, then we can alter the display with a simple < body onload="updateContent()" >

Golly gee; we don't need PHP to do that now do we! But that creates a structure for applying PHP provided content.

We change the webpage in question into a PHTML type to allow the server side PHP access to the content:

**foo.html becomes foo.phtml**

and we add to the top of that page. We also cause the php data to be loaded into globals for later access - - like this:

<?php
   global $msg1, $msg2, $textMsgPHP;

function getContent($filename) {
    if ($theData = file_get_contents($filename, FALSE)) {
        return "$theData";
    } else {
        echo "FAILED!";
        }
}
function returnContent($filename) {

  if ( $theData = getContent($filename) ) {
    // this works ONLY if $theData is one linear line (ie remove all \n)
    $textPHP = trim(preg_replace('/\r\n|\r|\n/', '', $theData));
    return "$textPHP";
  } else {
    echo '<span class="ERR">Error opening source file :(\n</span>';  # $filename!\n";
  } 
}

// preload the dynamic contents now for use later in the javascript (somewhere)
$msg1 =       returnContent('dummy_frame_data.txt');
$msg2 =       returnContent('dummy_frame_data_0.txt');
$textMsgPHP = returnContent('dummy_frame_data_1.txt');

?>

Now our javascripts can get to the PHP globals like this:

// by accessig the globals var textMsg = '< ? php global $textMsgPHP; echo "$textMsgPHP"; ? >';

In the javascript, replace

var textMsg = 'Say good night Gracy';

with: // using php returnContent()

var textMsg = '< ? php $msgX = returnContent('dummy_div_data_3.txt'); echo "$msgX" ? >';

Summary:

• the webpage to be modified MUST be a phtml or some php file
• the first thing in that file MUST be the < ? php to get the dynamic data ?>
• the php data MUST contain its own css styling (if content is in a frame)
• the javascript to use the dynamic data must be in this same file
• and we drop in/outof PHP as necessary to access the dynamic data
• Notice:- use single quotes in the outer javascript and ONLY double quotes in the dynamic php data

To be resolved: calling updateContent() with a filename and using it via onClick() instead of onLoad()

An example could be provided in the Sample_Dynamic_Frame.zip for your inspection, but didn't find a means to attach it

use "Content-type: application/x-www-form-urlencoded" instead of "application/json"

If the OK line is the first line and the last line is the dot you could consider slice them off like this:

TestString = '''OK SYS 10 LEN 20 12 43
1233a.fdads.txt,23 /data/a11134/a.txt
3232b.ddsss.txt,32 /data/d13f11/b.txt
3452d.dsasa.txt,1234 /data/c13af4/f.txt
.
'''
print('\n'.join(TestString.split()[1:-1]))

However if this is a very large string you may run into memory problems.

To set custom headers ON A REQUEST, build a request with the custom header before passing it to httpclient to send to http server. eg:

HttpClient client = HttpClients.custom().build();
HttpUriRequest request = RequestBuilder.get()
  .setUri(someURL)
  .setHeader(HttpHeaders.CONTENT_TYPE, "application/json")
  .build();
client.execute(request);

Default header is SET ON HTTPCLIENT to send on every request to the server.

public static void main(String[] args) throws IOException {
    String filePath = "/Users/myXml/VH181.xml";
    File xmlFile = new File(filePath);
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder;
    try {
        dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(xmlFile);
        doc.getDocumentElement().normalize();
        printElement(doc);
        System.out.println("XML file updated successfully");
    } catch (SAXException | ParserConfigurationException e1) {
        e1.printStackTrace();
    }
}
private static void printElement(Document someNode) {
    NodeList nodeList = someNode.getElementsByTagName("choiceInteraction");
    for(int z=0,size= nodeList.getLength();z<size; z++) {
            String Value = nodeList.item(z).getAttributes().getNamedItem("id").getNodeValue();
            System.out.println("Choice Interaction Id:"+Value);
        }
    }

we Can try this code using method

Use component scanning as given below, if com.project.action.PasswordHintAction is annotated with stereotype annotations

<context:component-scan base-package="com.project.action"/>

EDIT

I see your problem, in PasswordHintActionTest you are autowiring PasswordHintAction. But you did not create bean configuration for PasswordHintAction to autowire. Add one of stereotype annotation(@Component, @Service, @Controller) to PasswordHintAction like

@Component
public class PasswordHintAction extends BaseAction {
    private static final long serialVersionUID = -4037514607101222025L;
    private String username;

or create xml configuration in applicationcontext.xml like

<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />

git push -f origin master

use brute force ;-) Most likely you are trying to add a local folder that you created before creating the repo on git.

The problem for me is that I didn't include global.asax.cs in my project. And because I was copying files from a .net 4.5 to a 4.0 I didn't comment out lines that are not needed in 4.0. Because it was not included visual studio compiled it anyway without issues. But when I included it, it highlighted the lines that cause problems.

I just got that problem when converting from % formatting to .format().

Previous code:

"SET !TIMEOUT_STEP %{USER_TIMEOUT_STEP}d" % {'USER_TIMEOUT_STEP' = 3}

Problematic syntax:

"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format('USER_TIMEOUT_STEP' = 3)

The problem is that format is a function that needs parameters. They cannot be strings. That is one of worst python error messages I've ever seen.

Corrected code:

Basically here is the trick for Chromium (Chrome) browser:

getEventListeners(document.querySelector('your-element-selector'));

You can't use Microsoft.Office.Interop.Excel without having ms office installed.

Just search in google for some libraries, which allows to modify xls or xlsx:

• http://code.google.com/p/excellibrary/
• http://simpleooxml.codeplex.com/ (only xlsx)

I think the question has already been answered. I was also looking for something a webApi controller that has same signatured mehtods but different names. I was trying to implement the Calculator as WebApi. Calculator has 4 methods with the same signature but different names.

public class CalculatorController : ApiController
{
    [HttpGet]
    [ActionName("Add")]
    public string Add(int num1 = 1, int num2 = 1, int timeDelay = 1)
    {
        Thread.Sleep(1000 * timeDelay);
        return string.Format("Add = {0}", num1 + num2);
    }

    [HttpGet]
    [ActionName("Sub")]
    public string Sub(int num1 = 1, int num2 = 1, int timeDelay = 1)
    {
        Thread.Sleep(1000 * timeDelay);
        return string.Format("Subtract result = {0}", num1 - num2);
    }

    [HttpGet]
    [ActionName("Mul")]
    public string Mul(int num1 = 1, int num2 = 1, int timeDelay = 1)
    {
        Thread.Sleep(1000 * timeDelay);
        return string.Format("Multiplication result = {0}", num1 * num2);
    }

    [HttpGet]
    [ActionName("Div")]
    public string Div(int num1 = 1, int num2 = 1, int timeDelay = 1)
    {
        Thread.Sleep(1000 * timeDelay);
        return string.Format("Division result = {0}", num1 / num2);
    }
}

and in the WebApiConfig file you already have

 config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional });

Just set the authentication / authorisation on IIS and you are done!

Hope this helps!

Fix:

I chose the "ISAPI & CGI Restrictions" after clicking the server name (not the site name) in IIS Manager, and right clicked the "ASP.NET v4.0.30319" lines and chose "Allow".

After turning on ASP.NET from "Programs and Features > Turn Windows features on or off", you must install ASP.NET from the Windows command prompt. The MIME types don't ever show up, but after doing this command, I noticed these extensions showed up under the IIS web site "Handler Mappings" section of IIS Manager.

However, I still got this error. But if you do what I mentioned for the "Fix", this will go away.

HTTP Error 404.2 - Not Found
The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server.

For this you can use CSS3 background-size property. Write like this:

#div2{
    background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
    -moz-background-size:100% 100%;
    -webkit-background-size:100% 100%;
    background-size:100% 100%;
    height:180px;
    width:200px;
    border: 1px solid red;
}

Check this: http://jsfiddle.net/qdzaw/1/

open cmd as Administrator then try to register in both location

Try this:

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg), 
                       Base64.NO_WRAP);

I have the same problem, so I simply get JSON string and deserialize to my class:

HttpResponseMessage response = await client.GetAsync("Products");
//get data as Json string 
string data = await response.Content.ReadAsStringAsync();
//use JavaScriptSerializer from System.Web.Script.Serialization
JavaScriptSerializer JSserializer = new JavaScriptSerializer();
//deserialize to your class
products = JSserializer.Deserialize<List<Product>>(data);

Late GraveDig ... Just constrain your byte array to the file size.

FileInputStream fis = new FileInputStream( file );
byte[] byteArray= new byte[(int) file.length()];

Nobody mentioned the ability to use them in switch statements; I'll throw that in as well.

This allows arbitrarily complex enums to be used in a clean way without using instanceof, potentially confusing if sequences, or non-string/int switching values. The canonical example is a state machine.

myBook.Saved = true;
myBook.SaveCopyAs(xlsFileName);
myBook.Close(null, null, null);
myExcel.Workbooks.Close();
myExcel.Quit();

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

var settings = {
        "async": true,
        "crossDomain": true,
        "url": "<your URL Here>",
        "method": "GET",
        "headers": {
            "content-type": "application/x-www-form-urlencoded"
        },
        "data": {
            "username": "[email protected]",
            "password": "12345678"
        }
    }

    $.ajax(settings).done(function (response) {
        console.log(response);
    });

Here's a solution in pure PIL.

def blend_value(under, over, a):
    return (over*a + under*(255-a)) / 255

def blend_rgba(under, over):
    return tuple([blend_value(under[i], over[i], over[3]) for i in (0,1,2)] + [255])

white = (255, 255, 255, 255)

im = Image.open(object.logo.path)
p = im.load()
for y in range(im.size[1]):
    for x in range(im.size[0]):
        p[x,y] = blend_rgba(white, p[x,y])
im.save('/tmp/output.png')

I am using MacOSX with Eclipse 4.3 (Krepler). What I originally tried was to install Maven via the terminal using Brew. It installed correctly Maven 3.0.4. However when I tried to import any ready maven projects (File > Import > Maven) it would display the following two errors:

No marketplace entries found to handle Execution default-testResources

What I did is go to Help > Eclipse Marketplace and type "Maven" in the search bar and install the first default Maven client for Eclipse. Everything worked for me from this point.

Hope it helps to you too.

Maybe it will be useful for somebody. I faced with the same problem and in my case the reason was the SqlConnection was opened and not disposed in the method that I called in loop with about 2500 iterations. Connection pool was exhausted. Proper disposing solved the problem.

As of today, your best bet is to use:

img = cv2.imread(image_path)   # reads an image in the BGR format
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)   # BGR -> RGB

You'll see img will be a numpy array of type:

<class 'numpy.ndarray'>

It looks like your client is trying to connect to a non-existent server. In a shell window, run:

$ nc -l 5000

before running your Python code. It will act as a server listening on port 5000 for you to connect to. Then you can play with typing into your Python window and seeing it appear in the other terminal and vice versa.

For those doing video I cobbled the following based on @tsh :

import cv2 as cv
import numpy as np

def nothing(x):pass

cap = cv.VideoCapture(0)
cv.namedWindow('videoUI', cv.WINDOW_NORMAL)
cv.createTrackbar('T','videoUI',0,255,nothing)

while(True):
    ret, frame = cap.read()
    vid_gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
    thresh = cv.getTrackbarPos('T','videoUI');
    vid_bw = cv.threshold(vid_gray, thresh, 255, cv.THRESH_BINARY)[1]

    cv.imshow('videoUI',cv.flip(vid_bw,1))

    if cv.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv.destroyAllWindows()

Results in:

Unfortunately none of these answers solved the specific problem I had.

Here's a simple solution without having to mess with bash. In my case, it was getting gradle to work (for Android Studio).

Btw, These steps relate to OSX (Mountain Lion 10.8.5)

• Open up Terminal.

• Run the following command:

  sudo nano /etc/paths (or sudo vim /etc/paths for vim)

  

• Go to the bottom of the file, and enter the path you wish to add.
• Hit control-x to quit.
• Enter 'Y' to save the modified buffer.

• Open a new terminal window then type:

  echo $PATH

You should see the new path appended to the end of the PATH

I got these details from this post:

I hope that can help someone else

I don’t know how helpful will that be but in my case I just created another circle with border only and placed it “inside” the other shape.

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

My solution was use readAsBinaryString() and btoa() on its result.

uploadFileToServer(event) {
    var file = event.srcElement.files[0];
    console.log(file);
    var reader = new FileReader();
    reader.readAsBinaryString(file);

    reader.onload = function() {
        console.log(btoa(reader.result));
    };
    reader.onerror = function() {
        console.log('there are some problems');
    };
}

var pause_menu = {
    pause_button : { someProperty : "prop1", someOther : "prop2" },
    resume_button : { resumeProp : "prop", resumeProp2 : false },
    quit_button : false
};

then:

pause_menu.pause_button.someProperty //evaluates to "prop1"

etc etc.

Are you using the default controls boolean attribute on the video tag? If so, I believe all the supporting browsers have mute buttons. If you need to wire it up, set .muted to true on the element in javascript (use .prop for jquery because it's an IDL attribute.) The speaker icon on the volume control is the mute button on chrome,ff, safari, and opera for example

You do not have to reference std::cout or std::endl explicitly.
They are both included in the namespace std. using namespace std instead of using scope resolution operator :: every time makes is easier and cleaner.

#include<iostream>
#include<string>
using namespace std;

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

Currently i am using since this is trustable for getting location and calculating distance for my application...... i am using this for my taxi application.

use the fusion API that google developer have developed with fusion of GPS Sensor,Magnetometer,Accelerometer also using Wifi or cell location to calculate or estimate the location. It is also able to give location updates also inside the building accurately. for detail get to link https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderApi

A character frequency count is a common task for some applications (such as education) but not general enough to warrant inclusion with the core Java APIs. As such, you'll probably need to write your own function.

I tried different solutions, such as using a text editor to insert a new line and get the End Of Line character as recommended in the top answer above. None of these worked, unfortunately.

The solution that did finally work for me was very simple: I copy-pasted the content of a CSV file into a new blank CSV file, saved it, and the problem was gone.

First please follow the two lines of codes to update the action bar items before that you should set a condition in oncreateOptionMenu(). For example:

Boolean mISQuizItemSelected = false;

/**
 * Called to inflate the action bar menus
 *
 * @param menu
 *      the menu
 *
 * @return true, if successful
 */

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu items for use in the action bar

    inflater.inflate(R.menu.menu_demo, menu);

    //condition to hide the menus
    if (mISQuizItemSelected) {
        for (int i = 0; i < menu.size(); i++) {
            menu.getItem(i).setVisible(false);
        }
    }

    return super.onCreateOptionsMenu(menu);
}

/**
 * Called when the item on the action bar being selected.
 *
 * @param item
 *      menuitem being selected
 *
 * @return true if the menuitem id being selected is matched
 * false if none of the menuitems id are matched
 */
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getId() == R.id.action_quiz) {
        //to navigate based on the usertype either learner or leo
        mISQuizItemSelected = true;

        ActionBar actionBar = getActionBar();
        invalidateOptionMenu();
    }
}

mBitmap.eraseColor(Color.TRANSPARENT);

canvas.drawBitmap(mBitmap, 0, 0, mBitmapPaint);

With the perspective of the OS X v10.7 and iOS 5 launches, probably the first thing to recommend now is NSJSONSerialization, Apple's supplied JSON parser. Use third-party options only as a fallback if you find that class unavailable at runtime.

So, for example:

NSData *returnedData = ...JSON data, probably from a web request...

// probably check here that returnedData isn't nil; attempting
// NSJSONSerialization with nil data raises an exception, and who
// knows how your third-party library intends to react?

if(NSClassFromString(@"NSJSONSerialization"))
{
    NSError *error = nil;
    id object = [NSJSONSerialization
                      JSONObjectWithData:returnedData
                      options:0
                      error:&error];

Including the header afxwin.h signalizes use of MFC. The following instructions (based on those on CodeProject.com) could help to get MFC code compiling:

1. Download and install the Windows Driver Kit.

2. Select menu Tools > Options… > Projects and Solutions > VC++ Directories.

3. In the drop-down menu Show directories for select Include files.

4. Add the following paths (replace $(WDK_directory) with the directory where you installed Windows Driver Kit in the first step):

   $(WDK_directory)\inc\mfc42
   $(WDK_directory)\inc\atl30
   

   

5. In the drop-down menu Show directories for select Library files and add (replace $(WDK_directory) like before):

   $(WDK_directory)\lib\mfc\i386
   $(WDK_directory)\lib\atl\i386
   

   

6. In the $(WDK_directory)\inc\mfc42\afxwin.inl file, edit the following lines (starting from 1033):

   _AFXWIN_INLINE CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   to

   _AFXWIN_INLINE BOOL CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE BOOL CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   In other words, add BOOL after _AFXWIN_INLINE.

remove android:showAsAction="never" from res/menu folder from every xml file.

I use below simple solution:

This is your workbook and sheet:

XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("YOUR Workshhet");

then add data to your sheet with columns and rows. Once done with adding data to sheet write following code to autoSizeColumn width.

for (int columnIndex = 0; columnIndex < 15; columnIndex++) {
                    sheet.autoSizeColumn(columnIndex);
                }

Here, instead 15, you add the number of columns in your sheet.

Hope someone helps this.

There is a well-known function that can handle this:

from sklearn.model_selection import train_test_split
X, _, Y, _ = train_test_split(X,Y, test_size=0.0)

Just setting test_size to 0 will avoid splitting and give you shuffled data. Though it is usually used to split train and test data, it does shuffle them too.
From documentation

Split arrays or matrices into random train and test subsets

Quick utility that wraps input validation and next(ShuffleSplit().split(X, y)) and application to input data into a single call for splitting (and optionally subsampling) data in a oneliner.

A new clean way might be to write your xml like so:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE rootElement>

<rootElement>
 ....
</rootElement>

The above works in Eclipse Juno+

Found Answer.......!!!!!!!

Officially Microsoft Office 2003 Interop is not supported on Windows server 2008 by Microsoft.

But after a lot of permutations & combinations with the code and search, we came across one solution which works for our scenario.

The solution is to plug the difference between the way Windows 2003 and 2008 maintains its folder structure, because Office Interop depends on the desktop folder for file open/save intermediately. The 2003 system houses the desktop folder under systemprofile which is absent in 2008.

So when we create this folder on 2008 under the respective hierarchy as indicated below; the office Interop is able to save the file as required. This Desktop folder is required to be created under

C:\Windows\System32\config\systemprofile

AND

C:\Windows\SysWOW64\config\systemprofile

This worked for me...

Also do check if .NET 1.1 is installed because its needed by Interop and ot preinstalled by Windows Server 2008

Or you can also Use SaveCopyas() method ist just take onargument as filename string)

Thanks Guys..!

Actually you don't have to create an image at all. drawImage() will accept a Canvas as well as an Image object.

//grab the context from your destination canvas
var destCtx = destinationCanvas.getContext('2d');

//call its drawImage() function passing it the source canvas directly
destCtx.drawImage(sourceCanvas, 0, 0);

Way faster than using an ImageData object or Image element.

Note that sourceCanvas can be a HTMLImageElement, HTMLVideoElement, or a HTMLCanvasElement. As mentioned by Dave in a comment below this answer, you cannot use a canvas drawing context as your source. If you have a canvas drawing context instead of the canvas element it was created from, there is a reference to the original canvas element on the context under context.canvas.

Here is a jsPerf to demonstrate why this is the only right way to clone a canvas: http://jsperf.com/copying-a-canvas-element

You're not assigning any id to the text view, but you're using tv.getId() to pass it to the addRule method as a parameter. Try to set a unique id via tv.setId(int).

You could also use the LinearLayout with vertical orientation, that might be easier actually. I prefer LinearLayout over RelativeLayouts if not necessary otherwise.

I tried @JsonDetect and

@JsonIgnoreProperties(value = { "handler", "hibernateLazyInitializer" })

Neither of them worked for me. Using a third-party module seemed like a lot of work to me. So I just tried making a get call on any property of the lazy object before passing to jackson for serlization. The working code snippet looked something like this :

@RequestMapping(value = "/authenticate", produces = "application/json; charset=utf-8")
    @ResponseBody
    @Transactional
    public Account authenticate(Principal principal) {
        UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = (UsernamePasswordAuthenticationToken) principal;
        LoggedInUserDetails loggedInUserDetails = (LoggedInUserDetails) usernamePasswordAuthenticationToken.getPrincipal();
        User user = userRepository.findOne(loggedInUserDetails.getUserId());
        Account account = user.getAccount();
        account.getFullName();      //Since, account is lazy giving it directly to jackson for serlization didn't worked & hence, this quick-fix.
        return account;
    }

When creating a foreign key constraint, MySQL requires a usable index on both the referencing table and also on the referenced table. The index on the referencing table is created automatically if one doesn't exist, but the one on the referenced table needs to be created manually (Source). Yours appears to be missing.

Test case:

CREATE TABLE tbl_a (
    id int PRIMARY KEY,
    some_other_id int,
    value int
) ENGINE=INNODB;
Query OK, 0 rows affected (0.10 sec)

CREATE TABLE tbl_b (
    id int PRIMARY KEY,
    a_id int,
    FOREIGN KEY (a_id) REFERENCES tbl_a (some_other_id)
) ENGINE=INNODB;
ERROR 1005 (HY000): Can't create table 'e.tbl_b' (errno: 150)

But if we add an index on some_other_id:

CREATE INDEX ix_some_id ON tbl_a (some_other_id);
Query OK, 0 rows affected (0.11 sec)
Records: 0  Duplicates: 0  Warnings: 0

CREATE TABLE tbl_b (
    id int PRIMARY KEY,
    a_id int,
    FOREIGN KEY (a_id) REFERENCES tbl_a (some_other_id)
) ENGINE=INNODB;
Query OK, 0 rows affected (0.06 sec)

This is often not an issue in most situations, since the referenced field is often the primary key of the referenced table, and the primary key is indexed automatically.

Your local port 443 / 8181 / 3820 is used.

If you are on linux/unix:

• use netstat -an and lsof -n to check who is using this port

If you are on windows

• use netstat -an and tcpview to check.

Use this FAQ page: Apache log4net Frequently Asked Questions

About 3/4 of the way down it tells you how to enable log4net debugging by using application tracing. This will tell you where your issue is.

The basics are:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <appSettings>
        <add key="log4net.Internal.Debug" value="true"/>
    </appSettings>
</configuration>

And you see the trace in the standard output

nltk is convenient for a lot of language processing stuff. It has methods for frequency distribution built in. Something like:

import nltk
fdist = nltk.FreqDist(your_list) # creates a frequency distribution from a list
most_common = fdist.max()    # returns a single element
top_three = fdist.keys()[:3] # returns a list

(I know this is old but I wanted to post this for people like me who stumble upon it in the future) I personally just use this python code to decode base64 strings:

print open("FILE-WITH-STRING", "rb").read().decode("base64")

So you can run it in a bash script like this:

python -c 'print open("FILE-WITH-STRING", "rb").read().decode("base64")' > outputfile
file -i outputfile

twneale has also pointed out an even simpler solution: base64 -d So you can use it like this:

cat "FILE WITH STRING" | base64 -d > OUTPUTFILE
#Or You Can Do This
echo "STRING" | base64 -d > OUTPUTFILE

That will save the decoded string to outputfile and then attempt to identify file-type using either the file tool or you can try TrID. The following command will decode the string into a file and then use TrID to automatically identify the file's type and add the extension.

echo "STRING" | base64 -d > OUTPUTFILE; trid -ce OUTPUTFILE

Hope this help

If you have a single-threaded application, you can use a simple try/catch in the Main function, however, this does not cover exceptions that may be thrown outside of the Main function, on other threads, for example (as noted in other comments). This code demonstrates how an exception can cause the application to terminate even though you tried to handle it in Main (notice how the program exits gracefully if you press enter and allow the application to exit gracefully before the exception occurs, but if you let it run, it terminates quite unhappily):

static bool exiting = false;

static void Main(string[] args)
{
   try
   {
      System.Threading.Thread demo = new System.Threading.Thread(DemoThread);
      demo.Start();
      Console.ReadLine();
      exiting = true;
   }
   catch (Exception ex)
   {
      Console.WriteLine("Caught an exception");
   }
}

static void DemoThread()
{
   for(int i = 5; i >= 0; i--)
   {
      Console.Write("24/{0} =", i);
      Console.Out.Flush();
      Console.WriteLine("{0}", 24 / i);
      System.Threading.Thread.Sleep(1000);
      if (exiting) return;
   }
}

You can receive notification of when another thread throws an exception to perform some clean up before the application exits, but as far as I can tell, you cannot, from a console application, force the application to continue running if you do not handle the exception on the thread from which it is thrown without using some obscure compatibility options to make the application behave like it would have with .NET 1.x. This code demonstrates how the main thread can be notified of exceptions coming from other threads, but will still terminate unhappily:

static bool exiting = false;

static void Main(string[] args)
{
   try
   {
      System.Threading.Thread demo = new System.Threading.Thread(DemoThread);
      AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
      demo.Start();
      Console.ReadLine();
      exiting = true;
   }
   catch (Exception ex)
   {
      Console.WriteLine("Caught an exception");
   }
}

static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
   Console.WriteLine("Notified of a thread exception... application is terminating.");
}

static void DemoThread()
{
   for(int i = 5; i >= 0; i--)
   {
      Console.Write("24/{0} =", i);
      Console.Out.Flush();
      Console.WriteLine("{0}", 24 / i);
      System.Threading.Thread.Sleep(1000);
      if (exiting) return;
   }
}

So in my opinion, the cleanest way to handle it in a console application is to ensure that every thread has an exception handler at the root level:

static bool exiting = false;

static void Main(string[] args)
{
   try
   {
      System.Threading.Thread demo = new System.Threading.Thread(DemoThread);
      demo.Start();
      Console.ReadLine();
      exiting = true;
   }
   catch (Exception ex)
   {
      Console.WriteLine("Caught an exception");
   }
}

static void DemoThread()
{
   try
   {
      for (int i = 5; i >= 0; i--)
      {
         Console.Write("24/{0} =", i);
         Console.Out.Flush();
         Console.WriteLine("{0}", 24 / i);
         System.Threading.Thread.Sleep(1000);
         if (exiting) return;
      }
   }
   catch (Exception ex)
   {
      Console.WriteLine("Caught an exception on the other thread");
   }
}

Have a look at this article, it's not an exact match to your problem, but suits it:

• Craig Murphy - Excel – wordwrap row autosize issue

it's how I implemented it , the reason behind is if the class that you want to get the name from it's member is not static then you need to create an instanse of that and then get the member's name. so generic here comes to help

public static string GetName<TClass>(Expression<Func<TClass, object>> exp)
{
    MemberExpression body = exp.Body as MemberExpression;

    if (body == null)
    {
         UnaryExpression ubody = (UnaryExpression)exp.Body;
         body = ubody.Operand as MemberExpression;
    }

     return body.Member.Name;
}

the usage is like this

var label = ClassExtension.GetName<SomeClass>(x => x.Label); //x is refering to 'SomeClass'

/// <summary>
/// Contains global variables for project.
/// </summary>
public static class GlobalVar
{
/// <summary>
/// Global variable that is constant.
/// </summary>
public const string GlobalString = "Important Text";

/// <summary>
/// Static value protected by access routine.
/// </summary>
static int _globalValue;

/// <summary>
/// Access routine for global variable.
/// </summary>
public static int GlobalValue
{
get
{
    return _globalValue;
}
set
{
    _globalValue = value;
}
}

/// <summary>
/// Global static field.
/// </summary>
public static bool GlobalBoolean;
}

The root directory of a web application has a special significance and certain content can be present on in that folder. It can have a special file called as “Global.asax”. ASP.Net framework uses the content in the global.asax and creates a class at runtime which is inherited from HttpApplication. During the lifetime of an application, ASP.NET maintains a pool of Global.asax derived HttpApplication instances. When an application receives an http request, the ASP.Net page framework assigns one of these instances to process that request. That instance is responsible for managing the entire lifetime of the request it is assigned to and the instance can only be reused after the request has been completed when it is returned to the pool. The instance members in Global.asax cannot be used for sharing data across requests but static member can be. Global.asax can contain the event handlers of HttpApplication object and some other important methods which would execute at various points in a web application

Most of the answers are using a loop to go through the items. Here I have a variant that is using an EAFP way to do things: try to get an iterator on your input, if it succeeds run your function first on the first element, next on the remainder of this iterator. If you can't get an iterator, or if it's a string or a bytes object: yield the element.

Thanks to the suggestion from A. Kareem, who found out that my code was very slow, due to the fact that the recursion took too long for string and byte objects, here is an improved version of my code.

def flatten(x, it = None):
    try:
        if type(x) in (str, bytes):
            yield x
        else:
            if not it:
                it = iter(x)
            yield from flatten(next(it))
        if type(x) not in (str, bytes):
            yield from flatten(x, it)
    except StopIteration:
        pass
    except Exception:
        yield x

oldlist = [1,[[[["test",3]]]],((4,5,6)),[ bytes("test", encoding="utf-8"),7,[8,9]]]
newlist = [ x for x in flatten(oldlist) ]
print(newlist)
# [1, 'test', 3, 4, 5, 6, b'test', 7, 8, 9]

If using httplib.HTTPSConnection:

Please take a look at:

Changed in version 2.7.9:

This class now performs all the necessary certificate and hostname checks by default. To revert to the previous, unverified, behavior ssl._create_unverified_context() can be passed to the context parameter. You can use:

if hasattr(ssl, '_create_unverified_context'):
  ssl._create_default_https_context = ssl._create_unverified_context

Thanks to Aaron for pointing out that it's about locating the views, I misunderstood that.

[UPDATE] I just created a project that sends the user to an Area per default without messing with any of the code or lookup paths:

In global.asax, register as usual:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default",                                              // Route name
            "{controller}/{action}/{id}",                           // URL with parameters
            new { controller = "Home", action = "Index", id = ""}  // Parameter defaults,
        );
    }

in Application_Start(), make sure to use the following order;

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        RegisterRoutes(RouteTable.Routes);
    }

in you area registration, use

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            "ShopArea_default",
            "{controller}/{action}/{id}",
            new { action = "Index", id = "", controller = "MyRoute" },
            new { controller = "MyRoute" }
        );
    }

An example can be found at http://www.emphess.net/2010/01/31/areas-routes-and-defaults-in-mvc-2-rc/

I really hope that this is what you were asking for...

I don't think that writing a pseudo ViewEngine is the best solution in this case. (Lacking reputation, I can't comment). The WebFormsViewEngine is Area aware and contains AreaViewLocationFormats which is defined per default as

AreaViewLocationFormats = new[] {
        "~/Areas/{2}/Views/{1}/{0}.aspx",
        "~/Areas/{2}/Views/{1}/{0}.ascx",
        "~/Areas/{2}/Views/Shared/{0}.aspx",
        "~/Areas/{2}/Views/Shared/{0}.ascx",
    };

I believe you don't adhere to this convention. You posted

public ActionResult ActionY() 
{ 
    return View("~/Areas/AreaZ/views/ActionY.aspx"); 
} 

as a working hack, but that should be

   return View("~/Areas/AreaZ/views/ControllerX/ActionY.aspx"); 

IF you don't want to follow the convention, however, you might want to take a short path by either deriving from the WebFormViewEngine (that is done in MvcContrib, for example) where you can set the lookup paths in the constructor, or -a little hacky- by specifying your convention like this on Application_Start:

((VirtualPathProviderViewEngine)ViewEngines.Engines[0]).AreaViewLocationFormats = ...;

This should be performed with a little more care, of course, but I think it shows the idea. These fields are public in VirtualPathProviderViewEngine in MVC 2 RC.

If you use the Security framework or CommonCrypto libraries provided by Apple you do include crypto in your App and you have to answer yes - so simply because libraries were provided by Apple does not take you off the hook.

With regards to the original question, recent posts in the Apple Development Forums lead me to believe that you need to answer yes even if all you use is SSL.

go to configuration Manager under properties for your solution. Then make sure all projects and getting built, and this won't be a problem.

Kinda late to the party but I asked myself this question and saw this then thought of an answer. I don't know if someone already posted this. But essentially, I've noticed that all iterable types have __getitem__() in their dict. This is how you would check if an object was an iterable without even trying. (Pun intended)

def is_attr(arg):
    return '__getitem__' in dir(arg)

My problem was that I was trying to create a ASPX web application in a subfolder of a folder that already had a web.config file, and

So I opened up the parent folder in Visual Studio as a Web Site (Open > Web Site) I was able to add a new item ASPX page that had no issue parsing/loading.

Object.prototype.hasAttr = function(attr) {
    if(this.attr) {
        var _attr = this.attr(attr);
    } else {
        var _attr = this.getAttribute(attr);
    }
    return (typeof _attr !== "undefined" && _attr !== false && _attr !== null);      
};

I came a crossed this while writing my own function to do the same thing... I though I'd share in case someone else stumbles here. I added null because getAttribute() will return null if the attribute does not exist.

This method will allow you to check jQuery objects and regular javascript objects.

I resolved this, oddly enough, by installing System.Data.SQLite via the Nuget GUI application, as opposed to the package manager console.

Installing via the console didn't include the dependencies this library needs to run.

string path = AppDomain.CurrentDomain.GetData("DataDirectory").ToString();

This is probably a more "correct" way of getting it.

This may not be the best way for MVC ( https://stackoverflow.com/a/9461386/5869805 )

Below is how you render a view in Application_Error and write it to http response. You do not need to use redirect. This will prevent a second request to server, so the link in browser's address bar will stay same. This may be good or bad, it depends on what you want.

Global.asax.cs

protected void Application_Error()
{
    var exception = Server.GetLastError();
    // TODO do whatever you want with exception, such as logging, set errorMessage, etc.
    var errorMessage = "SOME FRIENDLY MESSAGE";

    // TODO: UPDATE BELOW FOUR PARAMETERS ACCORDING TO YOUR ERROR HANDLING ACTION
    var errorArea = "AREA";
    var errorController = "CONTROLLER";
    var errorAction = "ACTION";
    var pathToViewFile = $"~/Areas/{errorArea}/Views/{errorController}/{errorAction}.cshtml"; // THIS SHOULD BE THE PATH IN FILESYSTEM RELATIVE TO WHERE YOUR CSPROJ FILE IS!

    var requestControllerName = Convert.ToString(HttpContext.Current.Request.RequestContext?.RouteData?.Values["controller"]);
    var requestActionName = Convert.ToString(HttpContext.Current.Request.RequestContext?.RouteData?.Values["action"]);

    var controller = new BaseController(); // REPLACE THIS WITH YOUR BASE CONTROLLER CLASS
    var routeData = new RouteData { DataTokens = { { "area", errorArea } }, Values = { { "controller", errorController }, {"action", errorAction} } };
    var controllerContext = new ControllerContext(new HttpContextWrapper(HttpContext.Current), routeData, controller);
    controller.ControllerContext = controllerContext;

    var sw = new StringWriter();
    var razorView = new RazorView(controller.ControllerContext, pathToViewFile, "", false, null);
    var model = new ViewDataDictionary(new HandleErrorInfo(exception, requestControllerName, requestActionName));
    var viewContext = new ViewContext(controller.ControllerContext, razorView, model, new TempDataDictionary(), sw);
    viewContext.ViewBag.ErrorMessage = errorMessage;
    //TODO: add to ViewBag what you need
    razorView.Render(viewContext, sw);
    HttpContext.Current.Response.Write(sw);
    Server.ClearError();
    HttpContext.Current.Response.End(); // No more processing needed (ex: by default controller/action routing), flush the response out and raise EndRequest event.
}

View

@model HandleErrorInfo
@{
    ViewBag.Title = "Error";
    // TODO: SET YOUR LAYOUT
}
<div class="">
    ViewBag.ErrorMessage
</div>
@if(Model != null && HttpContext.Current.IsDebuggingEnabled)
{
    <div class="" style="background:khaki">
        <p>
            <b>Exception:</b> @Model.Exception.Message <br/>
            <b>Controller:</b> @Model.ControllerName <br/>
            <b>Action:</b> @Model.ActionName <br/>
        </p>
        <div>
            <pre>
                @Model.Exception.StackTrace
            </pre>
        </div>
    </div>
}

This is answer based on answer from iraSenthil but with annotation (Captor). In my opinion it has some advantages:

• it's shorter
• it's easier to read
• it can handle generics without warnings

Example:

@RunWith(MockitoJUnitRunner.class)
public class SomeTest{

    @Captor
    private ArgumentCaptor<List<SomeType>> captor;

    //...

    @Test 
    public void shouldTestArgsVals() {
        //...
        verify(mockedObject).someMethodOnMockedObject(captor.capture());

        assertThat(captor.getValue().getXXX(), is("expected"));
    }
}

$data =array();
$data['user_code']  = 'JOY' ;
$data['user_name']  = 'JOY' ;
$data['user_email'] = '[email protected]';

Thanks for the information here. I am finding this embedding useful and particularly for mobile especially with the embedded images' css file being cached.

To help make life easier, as my file editor(s) do not natively handle this, I made a couple of simple scripts for laptop/desktop editing work, share here in case they are any use to any one else. I have stuck with php as it is handling these things directly and very well.

Under Windows 8.1 say---

C:\Users\`your user name`\AppData\Roaming\Microsoft\Windows\SendTo

... there as an Administrator you can establish a shortcut to a batch file in your path. That batch file will call a php (cli) script.

You can then right click an image in file explorer, and SendTo the batchfile.

Ok Admiinstartor request, and wait for the black command shell windows to close.

Then just simply paste the result from clipboard in your into your text editor...

<img src="|">

or

 `background-image : url("|")` 

Following should be adaptable for other OS.

Batch file...

rem @echo 0ff
rem Puts 64 encoded version of a file on clipboard
php c:\utils\php\make64Encode.php %1

And with php.exe in your path, that calls a php (cli) script...

<?php 

function putClipboard($text){
 // Windows 8.1 workaround ...

  file_put_contents("output.txt", $text);

  exec("  clip < output.txt");

}


// somewhat based on http://perishablepress.com/php-encode-decode-data-urls/
// convert image to dataURL

$img_source = $argv[1]; // image path/name
$img_binary = fread(fopen($img_source, "r"), filesize($img_source));
$img_string = base64_encode($img_binary);

$finfo = finfo_open(FILEINFO_MIME_TYPE); 
$dataType = finfo_file($finfo, $img_source); 


$build = "data:" . $dataType . ";base64," . $img_string; 

putClipboard(trim($build));

?>

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

All right, so i'm a serious cryptkeeper here by dragging up this very old question, but there is a much simpler approach to this, which was touched on by @Baserz above. And that is to use a combination of C# Extension methods and caching (Do NOT use session).

In fact, Microsoft has already provided a number of such extensions in the Microsoft.AspNet.Identity.IdentityExtensions namespace. For instance, GetUserId() is an extension method that returns the user Id. There is also GetUserName() and FindFirstValue(), which returns claims based on the IPrincipal.

So you need only include the namespace, and then call User.Identity.GetUserName() to get the users name as configured by ASP.NET Identity.

I'm not certain if this is cached, since the older ASP.NET Identity is not open sourced, and I haven't bothered to reverse engineer it. However, if it's not then you can write your own extension method, that will cache this result for a specific amount of time.

DISCLAIMER: I'm the author of kids.cache.

You should check kids.cache, it provides a @cache decorator that works on python 2 and python 3. No dependencies, ~100 lines of code. It's very straightforward to use, for instance, with your code in mind, you could use it like this:

pip install kids.cache

Then

from kids.cache import cache
...
class MyClass(object):
    ...
    @cache            # <-- That's all you need to do
    @property
    def name(self):
        return 1 + 1  # supposedly expensive calculation

Or you could put the @cache decorator after the @property (same result).

Using cache on a property is called lazy evaluation, kids.cache can do much more (it works on function with any arguments, properties, any type of methods, and even classes...). For advanced users, kids.cache supports cachetools which provides fancy cache stores to python 2 and python 3 (LRU, LFU, TTL, RR cache).

IMPORTANT NOTE: the default cache store of kids.cache is a standard dict, which is not recommended for long running program with ever different queries as it would lead to an ever growing caching store. For this usage you can plugin other cache stores using for instance (@cache(use=cachetools.LRUCache(maxsize=2)) to decorate your function/property/class/method...)

None of the solutions described above worked for me. However reinstalling the package

Microsoft.CodeDom.Providers.DotNetCompilerPlatform 

using nuget gui is a (not too nice) walkaround

You can use a headless firefox with an extension. It's pretty annoying to get running but it does produce good results.

Check out this answer for more info.

A similar question was asked, but it didn't ask about statics.

Summary of what static, heap, and stack memory are:

• A static variable is basically a global variable, even if you cannot access it globally. Usually there is an address for it that is in the executable itself. There is only one copy for the entire program. No matter how many times you go into a function call (or class) (and in how many threads!) the variable is referring to the same memory location.

• The heap is a bunch of memory that can be used dynamically. If you want 4kb for an object then the dynamic allocator will look through its list of free space in the heap, pick out a 4kb chunk, and give it to you. Generally, the dynamic memory allocator (malloc, new, et c.) starts at the end of memory and works backwards.

• Explaining how a stack grows and shrinks is a bit outside the scope of this answer, but suffice to say you always add and remove from the end only. Stacks usually start high and grow down to lower addresses. You run out of memory when the stack meets the dynamic allocator somewhere in the middle (but refer to physical versus virtual memory and fragmentation). Multiple threads will require multiple stacks (the process generally reserves a minimum size for the stack).

When you would want to use each one:

• Statics/globals are useful for memory that you know you will always need and you know that you don't ever want to deallocate. (By the way, embedded environments may be thought of as having only static memory... the stack and heap are part of a known address space shared by a third memory type: the program code. Programs will often do dynamic allocation out of their static memory when they need things like linked lists. But regardless, the static memory itself (the buffer) is not itself "allocated", but rather other objects are allocated out of the memory held by the buffer for this purpose. You can do this in non-embedded as well, and console games will frequently eschew the built in dynamic memory mechanisms in favor of tightly controlling the allocation process by using buffers of preset sizes for all allocations.)

• Stack variables are useful for when you know that as long as the function is in scope (on the stack somewhere), you will want the variables to remain. Stacks are nice for variables that you need for the code where they are located, but which isn't needed outside that code. They are also really nice for when you are accessing a resource, like a file, and want the resource to automatically go away when you leave that code.

• Heap allocations (dynamically allocated memory) is useful when you want to be more flexible than the above. Frequently, a function gets called to respond to an event (the user clicks the "create box" button). The proper response may require allocating a new object (a new Box object) that should stick around long after the function is exited, so it can't be on the stack. But you don't know how many boxes you would want at the start of the program, so it can't be a static.

Garbage Collection

I've heard a lot lately about how great Garbage Collectors are, so maybe a bit of a dissenting voice would be helpful.

Garbage Collection is a wonderful mechanism for when performance is not a huge issue. I hear GCs are getting better and more sophisticated, but the fact is, you may be forced to accept a performance penalty (depending upon use case). And if you're lazy, it still may not work properly. At the best of times, Garbage Collectors realize that your memory goes away when it realizes that there are no more references to it (see reference counting). But, if you have an object that refers to itself (possibly by referring to another object which refers back), then reference counting alone will not indicate that the memory can be deleted. In this case, the GC needs to look at the entire reference soup and figure out if there are any islands that are only referred to by themselves. Offhand, I'd guess that to be an O(n^2) operation, but whatever it is, it can get bad if you are at all concerned with performance. (Edit: Martin B points out that it is O(n) for reasonably efficient algorithms. That is still O(n) too much if you are concerned with performance and can deallocate in constant time without garbage collection.)

Personally, when I hear people say that C++ doesn't have garbage collection, my mind tags that as a feature of C++, but I'm probably in the minority. Probably the hardest thing for people to learn about programming in C and C++ are pointers and how to correctly handle their dynamic memory allocations. Some other languages, like Python, would be horrible without GC, so I think it comes down to what you want out of a language. If you want dependable performance, then C++ without garbage collection is the only thing this side of Fortran that I can think of. If you want ease of use and training wheels (to save you from crashing without requiring that you learn "proper" memory management), pick something with a GC. Even if you know how to manage memory well, it will save you time which you can spend optimizing other code. There really isn't much of a performance penalty anymore, but if you really need dependable performance (and the ability to know exactly what is going on, when, under the covers) then I'd stick with C++. There is a reason that every major game engine that I've ever heard of is in C++ (if not C or assembly). Python, et al are fine for scripting, but not the main game engine.

OK, I found this post: http://msdn.microsoft.com/en-us/library/aa479319.aspx

with this very illustrative diagram:

in essence, to get at those exception details i need to store them myself in Global.asax, for later retrieval on my custom error page.

it seems the best way is to do the bulk of the work in Global.asax, with the custom error pages handling helpful content rather than logic.

I suggest that you create standards for your SQL scripting and stick to them. Also use templates to quickly create different types of stored procedures and functions. Here is a question about templates in SQL Server 2005 Management Studio

How do you create SQL Server 2005 stored procedure templates in SQL Server 2005 Management Studio?

store all your data initially

function PhoneListCtrl($scope, $http) {
  $http.get('phones/phones.json').success(function(data) {
    $scope.phones = data.splice(0, 5);
    $scope.allPhones = data;
  });

  $scope.orderProp = 'age';
  $scope.howMany = 5;
  //then here watch the howMany variable on the scope and update the phones array accordingly
  $scope.$watch("howMany", function(newValue, oldValue){
    $scope.phones = $scope.allPhones.splice(0,newValue)
  });
}

EDIT had accidentally put the watch outside the controller it should have been inside.

You can combine PIL's Image.thumbnail with sys.maxsize if your resize limit is only on one dimension (width or height).

For instance, if you want to resize an image so that its height is no more than 100px, while keeping aspect ratio, you can do something like this:

import sys
from PIL import Image

image.thumbnail([sys.maxsize, 100], Image.ANTIALIAS)

Keep in mind that Image.thumbnail will resize the image in place, which is different from Image.resize that instead returns the resized image without changing the original one.

I could NOT solve this. I had CORS enabled and working as long as the POST returned void (ASP.NET 4.0 - WEBAPI 1). When I tried to return a HttpResponseMessage, I started getting the HTTP 405 response.

Based on Llad's response above, I took a look at my own references.

I had the attribute [System.Web.Mvc.HttpPost] listed above my POST method.

I changed this to use:

[System.Web.Http.HttpPostAttribute]
[HttpOptions]
public HttpResponseMessage Post(object json)        
{
    ...
    return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
}

This fixed my woes. I hope this helps someone else.

For the sake of completeness, I had the following in my web.config:

<httpProtocol>
    <customHeaders>
        <clear />
        <add name="Access-Control-Expose-Headers " value="WWW-Authenticate"/>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, PATCH, DELETE" />
        <add name="Access-Control-Allow-Headers" value="accept, authorization, Content-Type" />
        <remove name="X-Powered-By" />
    </customHeaders>
</httpProtocol>

I just made some web scraping to discover the behaviour of JequeryUI datepicker, it was necessary for me because I'm not familiar with JS object so:

var month = $(".ui-datepicker-current-day").attr("data-month");
var year = $(".ui-datepicker-current-day").attr("data-year");
var day = $(".ui-state-active").text();

it just pick the value in relation of the changing of class, so you can implement the onchange event:

$(document).on('change', '#datepicker', function() { 
    var month = $(".ui-datepicker-current-day").attr("data-month");
    var year = $(".ui-datepicker-current-day").attr("data-year");
    var day= $(".ui-state-active").text();
   $("#chosenday").text( day + " " + month  + " " + year )  ;
                        
});

or check if the current day is selected:

   if( $("a").hasClass("ui-state-active") ){ 
     var month = $(".ui-datepicker-current-day").attr("data-month");
     var year = $(".ui-datepicker-current-day").attr("data-year");
     var day= $(".ui-state-active").text();
     $("#chosenday").text( day + " " + month  + " " + year );
    }

public DataSet GetDataSet(string ConnectionString, string SQL)

    da.SelectCommand = cmd;
    DataSet ds = new DataSet();

I would like share an example to understand the usage of stream().filter

Code Snippet: Sample program to identify even number.

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

public void fetchEvenNumber(){
        List<Integer> numberList = new ArrayList<>();
        numberList.add(10);
        numberList.add(11);
        numberList.add(12);
        numberList.add(13);
        numberList.add(14);
        numberList.add(15);

        List<Integer> evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());
        System.out.println(evenNumberListObj);
}

Output will be : [10, 12, 14]

List evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());

numberList: it is an ArrayList object contains list of numbers.

java.util.Collection.stream() : stream() will get the stream of collection, which will return the Stream of Integer.

filter: Returns a stream that match the given predicate. i.e based on given condition (i -> i%2 != 0) returns the matching stream.

collect: whatever the stream of Integer filter based in the filter condition, those integer will be put in a list.

If you want to get all new things in the past 5 minutes you would have to do some calculations, but its not hard...

First create an index on the property you want to match on (include sort direction -1 for descending and 1 for ascending)

db.things.createIndex({ createdAt: -1 }) // descending order on .createdAt

Then query for documents created in the last 5 minutes (60 seconds * 5 minutes)....because javascript's .getTime() returns milliseconds you need to mulitply by 1000 before you use it as input to the new Date() constructor.

db.things.find({
        createdAt: {
            $gte: new Date(new Date().getTime()-60*5*1000).toISOString()
         }
     })
     .count()

Explanation for new Date(new Date().getTime()-60*5*1000).toISOString() is as follows:

First we calculate "5 minutes ago":

1. new Date().getTime() gives us current time in milliseconds
2. We want to subtract 5 minutes (in ms) from that: 5*60*1000 -- I just multiply by 60 seconds so its easy to change. I can just change 5 to 120 if I want 2 hours (120 minutes).
3. new Date().getTime()-60*5*1000 gives us 1484383878676 (5 minutes ago in ms)

Now we need to feed that into a new Date() constructor to get the ISO string format required by MongoDB timestamps.

1. { $gte: new Date(resultFromAbove).toISOString() } (mongodb .find() query)
2. Since we can't have variables we do it all in one shot: new Date(new Date().getTime()-60*5*1000)
3. ...then convert to ISO string: .toISOString()
4. new Date(new Date().getTime()-60*5*1000).toISOString() gives us 2017-01-14T08:53:17.586Z

Of course this is a little easier with variables if you're using the node-mongodb-native driver, but this works in the mongo shell which is what I usually use to check things.

It seems that you'll need two fields, a choice list for the currency and a number field for the value.

A common technique in such case is to use a div or span for the display (form fields offscreen), and on click switch to the form elements for editing.

try this

$('#id').on('mousedown', function(event){
    event.preventDefault();
}

System.Diagnostics.Stopwatch is designed for this task.

C# just does a shallow copy when it passes by value unless the object in question executes ICloneable (which apparently the List class does not).

What this means is that it copies the List itself, but the references to the objects inside the list remain the same; that is, the pointers continue to reference the same objects as the original List.

If you change the values of the things your new List references, you change the original List also (since it is referencing the same objects). However, you then change what myList references entirely, to a new List, and now only the original List is referencing those integers.

Read the Passing Reference-Type Parameters section from this MSDN article on "Passing Parameters" for more information.

"How do I Clone a Generic List in C#" from StackOverflow talks about how to make a deep copy of a List.

Fastest by far (time is in comparison to Jacobs):

    d = 1/sqrt(V(1)*V(1)+V(2)*V(2)+V(3)*V(3)); 
    V1 = V*d;

Use the -J compression option for xz. And remember to man tar :)

tar cfJ <archive.tar.xz> <files>

Edit 2015-08-10:

If you're passing the arguments to tar with dashes (ex: tar -cf as opposed to tar cf), then the -f option must come last, since it specifies the filename (thanks to @A-B-B for pointing that out!). In that case, the command looks like:

tar -cJf <archive.tar.xz> <files>

$xml="l\rn";
$xml.="vv";

echo $xml;

Web Service is based on SOAP and return data in XML form. It support only HTTP protocol. It is not open source but can be consumed by any client that understands xml. It can be hosted only on IIS.

WCF is also based on SOAP and return data in XML form. It is the evolution of the web service(ASMX) and support various protocols like TCP, HTTP, HTTPS, Named Pipes, MSMQ. The main issue with WCF is, its tedious and extensive configuration. It is not open source but can be consumed by any client that understands xml. It can be hosted with in the applicaion or on IIS or using window service.

I have created a simple javascript library that retrieves google spreadsheet data (if they are published) via the JSON api:

https://github.com/mikeymckay/google-spreadsheet-javascript

You can see it in action here:

http://mikeymckay.github.com/google-spreadsheet-javascript/sample.html

You can use Ternary operator logic Ternary operator logic is the process of using "(condition)? (true return value) : (false return value)" statements to shorten your if/else structures. i.e

/* most basic usage */
$var = 5;
$var_is_greater_than_two = ($var > 2 ? true : false); // returns true

Since std::distance is only constant time for random-access iterators, I would probably prefer explicit iterator arithmetic. Also, since we're writing C++ code here, I do believe a more C++ idiomatic solution is preferable over a C-style approach.

    cout << it - begin << *it;
}

It is actually very easy. But there is no way you can achieve it directly. You need to select a service side technology. You can use anything for this part. And this is what we call a RESTful API or a SOAP API. It depends on you what to select. I have done many project with both. I would prefer REST. So what will happen you will have some scripts in your web server, and you know the URLs. For example we need to make a user registration. And for this we have

mydomain.com/v1/userregister.php

Now from the android side you will send an HTTP request to the above URL. And the above URL will handle the User Registration and will give you a response that whether the operation succeed or not.

For a complete detailed explanation of the above concept. You can visit the following link.

This can help others a lot!

First:

private static final String APP_DIR = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyAppFolderInStorage/";

private void install() {
    File file = new File(APP_DIR + fileName);

    if (file.exists()) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        String type = "application/vnd.android.package-archive";

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            Uri downloadedApk = FileProvider.getUriForFile(getContext(), "ir.greencode", file);
            intent.setDataAndType(downloadedApk, type);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        } else {
            intent.setDataAndType(Uri.fromFile(file), type);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        }

        getContext().startActivity(intent);
    } else {
        Toast.makeText(getContext(), "?File not found!", Toast.LENGTH_SHORT).show();
    }
}

Second: For android 7 and above you should define a provider in manifest like below!

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="ir.greencode"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/paths" />
    </provider>

Third: Define path.xml in res/xml folder like below! I'm using this path for internal storage if you want to change it to something else there is a few way! You can go to this link: FileProvider

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="your_folder_name" path="MyAppFolderInStorage/"/>
</paths>

Forth: You should add this permission in manifest:

<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>

Allows an application to request installing packages. Apps targeting APIs greater than 25 must hold this permission in order to use Intent.ACTION_INSTALL_PACKAGE.

Please make sure the provider authorities are the same!

I stumbled across this set of css properties which seem to vertically align the text in sized select elements in Firefox:

select
{
    box-sizing: content-box;
    -moz-box-sizing:content-box;
    -webkit-box-sizing:content-box;
}

If anything, though, it pushes the text down even farther in IE8. If I set the box-sizing property back to border-box, it at least doesn't make IE8 any worse (and FF still applies the -moz-box-sizing property). It would be nice to find a solution for IE, but I'm not holding my breath.

Edit: Nix this. It doesn't work after testing. For anyone interested, though, the problem seems to stem from built-in styles in FF's forms.css file affecting input and select elements. The property in question is line-height:normal !important. It cannot be overridden. I've tried. I discovered that if I delete the built-in property in Firebug I get a select element with reasonably vertically-centered text.

There's an easier way to think about this. Start with 1 bit. This can obviously represent 2 values (0 or 1). What happens when we add a bit? We can now represent twice as many values: the values we could represent before with a 0 appended and the values we could represent before with a 1 appended.

So the the number of values we can represent with n bits is just 2^n (2 to the power n)

use position css property and set top,right,bottom and left to Zero.. set z-index if needed in my case in i used text-indent because i dont want to show link "text" but if you want to show link "text" , just don't use text-indent

display:block;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
text-indent: -99999px;

Three simple choices.

Obvious

x, _ = func()

x, junk = func()

Hideous

x = func()[0]

And there are ways to do this with a decorator.

def val0( aFunc ):
    def pick0( *args, **kw ):
        return aFunc(*args,**kw)[0]
    return pick0

func0= val0(func)

Based on previous answers (but fixed)

using static System.IO.Path;

var dir = GetFileName(path?.TrimEnd(DirectorySeparatorChar, AltDirectorySeparatorChar));

Explanation of GetFileName from .NET source:

Returns the name and extension parts of the given path. The resulting string contains the characters of path that follow the last backslash ("\"), slash ("/"), or colon (":") character in path. The resulting string is the entire path if path contains no backslash after removing trailing slashes, slash, or colon characters. The resulting string is null if path is null.

And in PHPUnit Selenium test it's like this:

$text = $this->byCssSelector('.some-class-nmae')->attribute('innerHTML');

It looks like you want:

public static string GetRandomBits()

Without static, you would need an object before you can call the GetRandomBits() method. However, since the implementation of GetRandomBits() does not depend on the state of any Program object, it's best to declare it static.

Talvi's answer may still work, but that Youtube Javascript API has been marked as deprecated. You should now be using the newer Youtube IFrame API.

The documentation provides a few ways to accomplish video embedding, but for your goal, you'd include the following:

//load the IFrame Player API code asynchronously
var tag = document.createElement('script');

tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

//will be youtube player references once API is loaded
var players = [];

//gets called once the player API has loaded
function onYouTubeIframeAPIReady() {
    $('.myiframeclass').each(function() {
        var frame = $(this);

        //create each instance using the individual iframe id
        var player = new YT.Player(frame.attr('id'));

        players.push(player);
    });
}

//global stop button click handler
$('#mybutton').click(function(){

    //loop through each Youtube player instance and call stopVideo()
    for (var i in players) {
        var player = players[i];
        player.stopVideo();
    }
});

{
    "files.useExperimentalFileWatcher" : true
}

Tested with Visual Studio Code Version 1.26.1 on mac and win

If none of the above solutions work for any reason, like my case, try this:

  <script type="text/javascript">
    $(function()
    {
      $('[name="my_checkbox"]').change(function()
      {
        if ($(this).is(':checked')) {
           // Do something...
           alert('You can rock now...');
        };
      });
    });
  </script>

I see that for the accepted answer (recursivefn5), some folks are having issues with the explanation. so I'd try to clarify to the best of my knowledge.

1. The for loop runs for n/2 times because at each iteration, we are increasing i (the counter) by a factor of 2. so say n = 10, the for loop will run 10/2 = 5 times i.e when i is 0,2,4,6 and 8 respectively.

2. In the same regard, the recursive call is reduced by a factor of 5 for every time it is called i.e it runs for n/5 times. Again assume n = 10, the recursive call runs for 10/5 = 2 times i.e when n is 10 and 5 and then it hits the base case and terminates.

3. Calculating the total run time, the for loop runs n/2 times for every time we call the recursive function. since the recursive fxn runs n/5 times (in 2 above),the for loop runs for (n/2) * (n/5) = (n^2)/10 times, which translates to an overall Big O runtime of O(n^2) - ignoring the constant (1/10)...

I would have used version 2 of the code in this case. Since you have the full-list of products available and that's what expected by the "consumer" of this method call, it would be required to send the complete information back to the caller.

If caller of this method requires "one" information at a time and the consumption of the next information is on-demand basis, then it would be beneficial to use yield return which will make sure the command of execution will be returned to the caller when a unit of information is available.

Some examples where one could use yield return is:

1. Complex, step-by-step calculation where caller is waiting for data of a step at a time
2. Paging in GUI - where user might never reach to the last page and only sub-set of information is required to be disclosed on current page

To answer your questions, I would have used the version 2.

Something that really needs to be pointed out is that there are really two aspects to this question - the theoretical aspect and the implementations aspect.

First, let's look at the theoretical aspect. You need to understand what a process is conceptually to understand the difference between a process and a thread and what's shared between them.

We have the following from section 2.2.2 The Classical Thread Model in Modern Operating Systems 3e by Tanenbaum:

The process model is based on two independent concepts: resource grouping and execution. Sometimes it is use­ful to separate them; this is where threads come in....

He continues:

One way of looking at a process is that it is a way to group related resources together. A process has an address space containing program text and data, as well as other resources. These resource may include open files, child processes, pending alarms, signal handlers, accounting information, and more. By putting them together in the form of a process, they can be managed more easily. The other concept a process has is a thread of execution, usually shortened to just thread. The thread has a program counter that keeps track of which instruc­tion to execute next. It has registers, which hold its current working variables. It has a stack, which contains the execution history, with one frame for each proce­dure called but not yet returned from. Although a thread must execute in some process, the thread and its process are different concepts and can be treated sepa­rately. Processes are used to group resources together; threads are the entities scheduled for execution on the CPU.

Further down he provides the following table:

Per process items             | Per thread items
------------------------------|-----------------
Address space                 | Program counter
Global variables              | Registers
Open files                    | Stack
Child processes               | State
Pending alarms                |
Signals and signal handlers   |
Accounting information        |

The above is what you need for threads to work. As others have pointed out, things like segments are OS dependant implementation details.

I like Peter Ajtai's concat-then-unique solution, but the code's not very clear. Here's a nicer alternative:

function unique(x) {
  return x.filter(function(elem, index) { return x.indexOf(elem) === index; });
};
function union(x, y) {
  return unique(x.concat(y));
};

Since indexOf returns the index of the first occurence, we check this against the current element's index (the second parameter to the filter predicate).

Can be done in one line:

-- the following expression calculates ==> max(@val1, @val2)
SELECT 0.5 * ((@val1 + @val2) + ABS(@val1 - @val2)) 

Edit: If you're dealing with very large numbers you'll have to convert the value variables into bigint in order to avoid an integer overflow.

This is the safest solution:

git stash

Now you can do whatever you want without fear of conflicts.

For instance:

git checkout origin/master

If you want to include the remote changes in the master branch you can do:

git reset --hard origin/master

This will make you branch "master" to point to "origin/master".

Improvements

Your looping structure could be made faster:

   var count = 0;
   for(var i=0, n=array.length; i < n; i++) 
   { 
      count += array[i]; 
   }

This retrieves array.length once, rather than with each iteration. The optimization is made by caching the value.

If you really want to speed it up:

   var count=0;
   for (var i=array.length; i--;) {
     count+=array[i];
   }

This is equivalent to a while reverse loop. It caches the value and is compared to 0, thus faster iteration.

For a more complete comparison list, see my JSFiddle.
Note: array.reduce is horrible there, but in Firebug Console it is fastest.

Compare Structures

I started a JSPerf for array summations. It was quickly constructed and not guaranteed to be complete or accurate, but that's what edit is for :)

The purpose of mocking types is to sever dependencies in order to isolate the test to a specific unit. Stubs are simple surrogates, while mocks are surrogates that can verify usage. A mocking framework is a tool that will help you generate stubs and mocks.

EDIT: Since the original wording mention "type mocking" I got the impression that this related to TypeMock. In my experience the general term is just "mocking". Please feel free to disregard the below info specifically on TypeMock.

TypeMock Isolator differs from most other mocking framework in that it works my modifying IL on the fly. That allows it to mock types and instances that most other frameworks cannot mock. To mock these types/instances with other frameworks you must provide your own abstractions and mock these.

TypeMock offers great flexibility at the expense of a clean runtime environment. As a side effect of the way TypeMock achieves its results you will sometimes get very strange results when using TypeMock.

It's not a matter of security. The HTTP protocol defines GET-type requests as being idempotent, while POSTs may have side effects. In plain English, that means that GET is used for viewing something, without changing it, while POST is used for changing something. For example, a search page should use GET, while a form that changes your password should use POST.

Also, note that PHP confuses the concepts a bit. A POST request gets input from the query string and through the request body. A GET request just gets input from the query string. So a POST request is a superset of a GET request; you can use $_GET in a POST request, and it may even make sense to have parameters with the same name in $_POST and $_GET that mean different things.

For example, let's say you have a form for editing an article. The article-id may be in the query string (and, so, available through $_GET['id']), but let's say that you want to change the article-id. The new id may then be present in the request body ($_POST['id']). OK, perhaps that's not the best example, but I hope it illustrates the difference between the two.

Sync and Build...

The assignment does not remove the newline characters, it's actually the echo doing this. You need simply put quotes around the string to maintain those newlines:

echo "$testvar"

This will give the result you want. See the following transcript for a demo:

pax> cat num1.txt ; x=$(cat num1.txt)
line 1
line 2

pax> echo $x ; echo '===' ; echo "$x"
line 1 line 2
===
line 1
line 2

The reason why newlines are replaced with spaces is not entirely to do with the echo command, rather it's a combination of things.

When given a command line, bash splits it into words according to the documentation for the IFS variable:

IFS: The Internal Field Separator that is used for word splitting after expansion ... the default value is <space><tab><newline>.

That specifies that, by default, any of those three characters can be used to split your command into individual words. After that, the word separators are gone, all you have left is a list of words.

Combine that with the echo documentation (a bash internal command), and you'll see why the spaces are output:

echo [-neE] [arg ...]: Output the args, separated by spaces, followed by a newline.

When you use echo "$x", it forces the entire x variable to be a single word according to bash, hence it's not split. You can see that with:

pax> function count {
...>    echo $#
...> }
pax> count 1 2 3
3
pax> count a b c d
4
pax> count $x
4
pax> count "$x"
1

Here, the count function simply prints out the number of arguments given. The 1 2 3 and a b c d variants show it in action.

Then we try it with the two variations on the x variable. The one without quotes shows that there are four words, "test", "1", "test" and "2". Adding the quotes makes it one single word "test 1\ntest 2".

Just for completeness and because it was asked in the comments - there's also the CSS audit tool in Chrome now for the same purpose. Some details here:

@Ed courtenay, @James, I have one stupid question. How to keep user away from this file?(File containing expiry date). If the user has installation rights, then obviously user has access to view files also. Changing the extension of file wont help. So, how to keep this file safe and away from users hands?

The simplest way to see ram usage if you have RDP access / console access would be just launch task manager - click processes - show processes from all users, sort by RAM - This will give you SQL's usage.

As was mentioned above, to decrease the size (which will take effect immediately, no restart required) launch sql management studio, click the server, properties - memory and decrease the max. There's no exactly perfect number, but make sure the server has ram free for other tasks.

The answers about perfmon are correct and should be used, but they aren't as obvious a method as task manager IMHO.

I believe there are a lot of good articles about this around the Web, but here is a short summary.

Both UTF-8 and UTF-16 are variable length encodings. However, in UTF-8 a character may occupy a minimum of 8 bits, while in UTF-16 character length starts with 16 bits.

Main UTF-8 pros:

• Basic ASCII characters like digits, Latin characters with no accents, etc. occupy one byte which is identical to US-ASCII representation. This way all US-ASCII strings become valid UTF-8, which provides decent backwards compatibility in many cases.
• No null bytes, which allows to use null-terminated strings, this introduces a great deal of backwards compatibility too.
• UTF-8 is independent of byte order, so you don't have to worry about Big Endian / Little Endian issue.

Main UTF-8 cons:

• Many common characters have different length, which slows indexing by codepoint and calculating a codepoint count terribly.
• Even though byte order doesn't matter, sometimes UTF-8 still has BOM (byte order mark) which serves to notify that the text is encoded in UTF-8, and also breaks compatibility with ASCII software even if the text only contains ASCII characters. Microsoft software (like Notepad) especially likes to add BOM to UTF-8.

Main UTF-16 pros:

• BMP (basic multilingual plane) characters, including Latin, Cyrillic, most Chinese (the PRC made support for some codepoints outside BMP mandatory), most Japanese can be represented with 2 bytes. This speeds up indexing and calculating codepoint count in case the text does not contain supplementary characters.
• Even if the text has supplementary characters, they are still represented by pairs of 16-bit values, which means that the total length is still divisible by two and allows to use 16-bit char as the primitive component of the string.

Main UTF-16 cons:

• Lots of null bytes in US-ASCII strings, which means no null-terminated strings and a lot of wasted memory.
• Using it as a fixed-length encoding “mostly works” in many common scenarios (especially in US / EU / countries with Cyrillic alphabets / Israel / Arab countries / Iran and many others), often leading to broken support where it doesn't. This means the programmers have to be aware of surrogate pairs and handle them properly in cases where it matters!
• It's variable length, so counting or indexing codepoints is costly, though less than UTF-8.

In general, UTF-16 is usually better for in-memory representation because BE/LE is irrelevant there (just use native order) and indexing is faster (just don't forget to handle surrogate pairs properly). UTF-8, on the other hand, is extremely good for text files and network protocols because there is no BE/LE issue and null-termination often comes in handy, as well as ASCII-compatibility.

It wasn't obvious to me that although you can accept a Collection as a request param, but on the consumer side you still have to pass in the collection items as comma separated values.

For example if the server side api looks like this:

@PostMapping("/post-topics")
public void handleSubscriptions(@RequestParam("topics") Collection<String> topicStrings) {

    topicStrings.forEach(topic -> System.out.println(topic));
}

Directly passing in a collection to the RestTemplate as a RequestParam like below will result in data corruption

public void subscribeToTopics() {

    List<String> topics = Arrays.asList("first-topic", "second-topic", "third-topic");

    RestTemplate restTemplate = new RestTemplate();
    restTemplate.postForEntity(
            "http://localhost:8088/post-topics?topics={topics}",
            null,
            ResponseEntity.class,
            topics);
}

Instead you can use

public void subscribeToTopics() {

    List<String> topicStrings = Arrays.asList("first-topic", "second-topic", "third-topic");
    String topics = String.join(",",topicStrings);

    RestTemplate restTemplate = new RestTemplate();
    restTemplate.postForEntity(
            "http://localhost:8088/post-topics?topics={topics}",
            null,
            ResponseEntity.class,
            topics);
}

The complete example can be found here, hope it saves someone the headache :)

I had this warning possibly because of calling setState from an effect hook (This is discussed in these 3 issues linked together).

Anyway, upgrading the react version removed the warning.

The container div, and sometimes content div, are almost always used to allow for more sophisticated CSS styling. The body tag is special in some ways. Browsers don't treat it like a normal div; its position and dimensions are tied to the browser window.

But a container div is just a div and you can style it with margins and borders. You can give it a fixed width, and you can center it with margin-left: auto; margin-right: auto.

Plus, content, like a copyright notice for example, can go on the outside of the container div, but it can't go on the outside of the body, allowing for content on the outside of a border.

C99 requires that when a/b is representable:

(a/b) * b + a%b shall equal a

This makes sense, logically. Right?

Let's see what this leads to:

Example A. 5/(-3) is -1

=> (-1) * (-3) + 5%(-3) = 5

This can only happen if 5%(-3) is 2.

Example B. (-5)/3 is -1

=> (-1) * 3 + (-5)%3 = -5

This can only happen if (-5)%3 is -2

    var valueOfTextBox=$("#result").val();
    var valueOfSelectedCheckbox=$("#radio:checked").val();

    $.ajax({
    url: 'result.php',
    type: 'POST',
    data: { forValue: valueOfTextBox, check : valueOfSelectedCheckbox } ,
    beforeSend: function() {

          $("#loader").show();
       },
    success: function (response) {
       $("#loader").hide();
       $("#answer").text(response);
    },
    error: function () {
        //$("#loader").show();
        alert("error occured");
    }
    }); 

This code strip all event listeners

var old_element=document.getElementsByClassName(".update-cart");    
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);  

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

    $message = "This is test message that contain filter world test3";

    $filterWords = array('test1', 'test2', 'test3');

    $messageAfterFilter =  str_replace($filterWords, '',$message);

    if( strlen($messageAfterFilter) != strlen($message) )
        echo 'message is filtered';

        echo 'not filtered';

If you have to delete multiple values in an array and the entries in that array are objects or structured data, [array_filter][1] is your best bet. Those entries that return a true from the callback function will be retained.

$array = [
    ['x'=>1,'y'=>2,'z'=>3], 
    ['x'=>2,'y'=>4,'z'=>6], 
    ['x'=>3,'y'=>6,'z'=>9]
];

$results = array_filter($array, function($value) {
    return $value['x'] > 2; 
}); //=> [['x'=>3,'y'=>6,z=>'9']]

On Python 3.4, the pathlib module was added, and the following code will reliably open a file in the same directory as the current script:

from pathlib import Path

p = Path(__file__).with_name('file.txt')
with p.open('r') as f:
    print(f.read())

You can also use parent.absolute() to get directory value as a string if needed:

p = Path(__file__)
dir_abs = p.parent.absolute()  # Will return the executable directory absolute path

You could roll your own:

function resolve(objectToGetValueFrom, stringOfDotSeparatedParameters) {
    var returnObject = objectToGetValueFrom,
        parameters = stringOfDotSeparatedParameters.split('.'),
        i,
        parameter;

    for (i = 0; i < parameters.length; i++) {
        parameter = parameters[i];

        returnObject = returnObject[parameter];

        if (returnObject === undefined) {
            break;
        }
    }
    return returnObject;
};

And use it like this:

var result = resolve(obj, 'a.b.c.d'); 

* result is undefined if any one of a, b, c or d is undefined.

I think you want to put a, in front of a:link (a, a:link) in your CSS file. The only way I could get rid of that awful default blue link color. I'm not sure if this was necessary for earlier version of the browsers we have, because it's supposed to work without a

   FROM TX_Master_PCBA WHERE SERIAL_NO='0500030309'

)

You need to do some escaping I think.

This is likely due to your system's overcommit handling mode.

In the default mode, 0,

Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slightly more memory in this mode. This is the default.

The exact heuristic used is not well explained here, but this is discussed more on Linux over commit heuristic and on this page.

You can check your current overcommit mode by running

$ cat /proc/sys/vm/overcommit_memory
0

In this case you're allocating

>>> 156816 * 36 * 53806 / 1024.0**3
282.8939827680588

~282 GB, and the kernel is saying well obviously there's no way I'm going to be able to commit that many physical pages to this, and it refuses the allocation.

If (as root) you run:

$ echo 1 > /proc/sys/vm/overcommit_memory

This will enable "always overcommit" mode, and you'll find that indeed the system will allow you to make the allocation no matter how large it is (within 64-bit memory addressing at least).

I tested this myself on a machine with 32 GB of RAM. With overcommit mode 0 I also got a MemoryError, but after changing it back to 1 it works:

>>> import numpy as np
>>> a = np.zeros((156816, 36, 53806), dtype='uint8')
>>> a.nbytes
303755101056

You can then go ahead and write to any location within the array, and the system will only allocate physical pages when you explicitly write to that page. So you can use this, with care, for sparse arrays.

$encoded_data = base64_encode(file_get_contents('path-to-your-image.jpg'));    

@cnicutar and @Pete Becker have already pointed out the possibility of using noskipws/unsetting skipws to read a character at a time without skipping over white space characters in the input.

Another possibility would be to use an istreambuf_iterator to read the data. Along with this, I'd generally use a standard algorithm like std::transform to do the reading and processing.

Just for example, let's assume we wanted to do a Caesar-like cipher, copying from standard input to standard output, but adding 3 to every upper-case character, so A would become D, B could become E, etc. (and at the end, it would wrap around so XYZ converted to ABC.

If we were going to do that in C, we'd typically use a loop something like this:

int ch;
while (EOF != (ch = getchar())) {
    if (isupper(ch)) 
        ch = ((ch - 'A') +3) % 26 + 'A';
    putchar(ch);
}

To do the same thing in C++, I'd probably write the code more like this:

std::transform(std::istreambuf_iterator<char>(std::cin),
               std::istreambuf_iterator<char>(),
               std::ostreambuf_iterator<char>(std::cout),
               [](int ch) { return isupper(ch) ? ((ch - 'A') + 3) % 26 + 'A' : ch;});

Doing the job this way, you receive the consecutive characters as the values of the parameter passed to (in this case) the lambda function (though you could use an explicit functor instead of a lambda if you preferred).

Here's another way of transferring large tables. I've just transferred 105 million rows between two servers using this. Quite quick too.

1. Right-click on the database and choose Tasks/Export Data.
2. A wizard will take you through the steps but you choosing your SQL server client as the data source and target will allow you to select the database and table(s) you wish to transfer.

For more information, see https://www.mssqltips.com/sqlservertutorial/202/simple-way-to-export-data-from-sql-server/

This Code May be Help you : [ Both maximizing and preventing resizing on a JFrame ]

frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
frame.setVisible(true);
frame.setResizable(false);

Another option is Sheet1.Rows(x & ":" & Sheet1.Rows.Count).ClearContents (or .Clear). The reason you might want to use this method instead of .Delete is because any cells with dependencies in the deleted range (e.g. formulas that refer to those cells, even if empty) will end up showing #REF. This method will preserve formula references to the cleared cells.

That's exactly how you use it. There is a possibility that the address you have does not correspond to something directly in your source code though.

For example:

$ cat t.c
#include <stdio.h>
int main()
{
    printf("hello\n");
    return 0;
}
$ gcc -g t.c
$ addr2line -e a.out 0x400534
/tmp/t.c:3
$ addr2line -e a.out 0x400550
??:0

0x400534 is the address of main in my case. 0x400408 is also a valid function address in a.out, but it's a piece of code generated/imported by GCC, that has no debug info. (In this case, __libc_csu_init. You can see the layout of your executable with readelf -a your_exe.)

Other times when addr2line will fail is if you're including a library that has no debug information.

My situation was slightly different, I did git reset HEAD~ three times.

To undo it I had to do

git reset HEAD@{3}

so you should be able to do

git reset HEAD@{N}

But if you have done git reset using

git reset HEAD~3

you will need to do

git reset HEAD@{1}

{N} represents the number of operations in reflog, as Mark pointed out in the comments.

To read more than one json tip (array, attribute) I did the following.

var jVariable = JsonConvert.DeserializeObject<YourCommentaryClass>(jsonVariableContent);

change to

var jVariable = JsonConvert.DeserializeObject <List<YourCommentaryClass>>(jsonVariableContent);

Because you cannot see all the bits in the method used in the foreach loop. Example foreach loop

foreach (jsonDonanimSimple Variable in jVariable)
                {    
                    debugOutput(jVariable.Id.ToString());
                    debugOutput(jVariable.Header.ToString());
                    debugOutput(jVariable.Content.ToString());
                }

I also received an error in this loop and changed it as follows.

foreach (jsonDonanimSimple Variable in jVariable)
                    {    
                        debugOutput(Variable.Id.ToString());
                        debugOutput(Variable.Header.ToString());
                        debugOutput(Variable.Content.ToString());
                    }

I added some padding on the right of all labels (padding-right:8px) just to make the example slight less horrible looking, but that should be done more carefully in a real project (adding padding to all other elements would also be a good idea).

You can also do this with one query too using a join like so:

UPDATE table1,table2 SET table1.col=a,table2.col2=b
WHERE items.id=month.id;

And then just send this one query, of course. You can read more about joins here: http://dev.mysql.com/doc/refman/5.0/en/join.html. There's also a couple restrictions for ordering and limiting on multiple table updates you can read about here: http://dev.mysql.com/doc/refman/5.0/en/update.html (just ctrl+f "join").

In Java script you declare array as below:

var array=[];
array.push();

and for arraylist or object or array you have to use json; and Serialize it using json by using following code:

 var serializedMyObj = JSON.stringify(myObj);

System.Reflection.Assembly.GetEntryAssembly().Location;

Just few more details:

• Add mysql field

`image` blob

• Get data from image

$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));

• Insert image data into db

$sql = "INSERT INTO `product_images` (`id`, `image`) VALUES ('1', '{$image}')";

• Show image to the web

<img src="data:image/png;base64,'.base64_encode($row['image']).'">

• End

You need to include jQueryUI for the extended easing options.

I think there may be an option to only include the easing in the download, or at least just the base library plus easing.

There is Ogham library. The code to send SMS is easy to write (it automatically handles character encoding and message splitting). The real SMS is sent either using SMPP protocol (standard SMS protocol) or through a provider. You can even test your code locally with a SMPP server to check the result of your SMS before paying for real SMS sending.

You can make an auth section in your .hgrc or Mercurial.ini file, like so:

[auth]
bb.prefix = https://bitbucket.org/repo/path
bb.username = foo
bb.password = foo_passwd

The ‘bb’ part is an arbitrary identifier and is used to match prefix with username and password - handy for managing different username/password combos with different sites (prefix)

You can also only specify the user name, then you will just have to type your password when you push.

I would also recommend to take a look at the keyring extension. Because it stores the password in your system’s key ring instead of a plain text file, it is more secure. It is bundled with TortoiseHg on Windows, and there is currently a discussion about distributing it as a bundled extension on all platforms.

There is the RowIndex property for the CurrentCell property for the DataGridView.

datagridview.CurrentCell.RowIndex

Handle the SelectionChanged event and find the index of the selected row as above.

If you want to use the default settings from http package, so you don't need to create a new Transport and Client object, you can change to ignore the certificate verification like this:

tr := http.DefaultTransport.(*http.Transport)
tr.TLSClientConfig.InsecureSkipVerify = true

Your question is vague (are you always looking for the first part?), but you can get the exact output you asked for with string.Split:

string[] substrings = a.Split(',');
b = substrings[0];
Console.WriteLine(b);

Output:

abc

Adding to @Josh's example;

fName = [FILE TO OPEN]
if os.path.exists(fName):
    with open(fName, 'rb') as f:
        #add you code to handle the file contents here.
elif IOError:
    print "Unable to open file: "+str(fName)

This way you can attempt to open the file, but if it doesn't exist (if it raises an IOError), alert the user!

The fastest way I found was this:

var obj = new {Id = thing.Id, Name = thing.Name, Age = 30};

If you are using unix, you need to write a shellscript to run you java batch first.

After that, in unix, you run this command "crontab -e" to edit crontab script. In order to configure crontab, please refer to this article http://www.thegeekstuff.com/2009/06/15-practical-crontab-examples/

Save your crontab setting. Then wait for the time to come, program will run automatically.

It does not make sense to put your business layer in the Model for an MVC project.

Say that your boss decides to change the presentation layer to something else, you would be screwed! The business layer should be a separate assembly. A Model contains the data that comes from the business layer that passes to the view to display. Then on post for example, the model binds to a Person class that resides in the business layer and calls PersonBusiness.SavePerson(p); where p is the Person class. Here's what I do (BusinessError class is missing but would go in the BusinessLayer too):

In MVVM (wich makes a lot of things a lot easier - you should try it) you would have two properties in your ViewModel Text that is bound to your TextBox and you would have an ICommand property Apply (or similar) that is bound to the button:

<Button Command="Apply">Apply</Button>

The ICommand interface has a Method CanExecute that is where you return true if (!string.IsNullOrWhiteSpace(this.Text). The rest is done by WPF for you (enabling/disabling, executing the actual command on click).

The linked article explains it in detail.

This can be done fairly easily with SyntaxHighlighter. I have step-by-step instructions for setting up SyntaxHighlighter in Blogger on my blog. SyntaxHighlighter is very easy to use. It lets you post snippets in raw form and then wrap them in pre blocks like:

<pre name="code" class="brush: erlang"><![CDATA[

-export([string_strip_right/1, reverse_tl_reverse/1, bench/0]).

bench() -> [nbench(N) || N <- [1,1000,1000000]].

nbench(N) -> {N, bench(["a" || _ <- lists:seq(1,N)])}.

bench(String) ->
    {{string_strip_right,
    lists:sum([
        element(1, timer:tc(trim, string_strip_right, [String]))

    {reverse_tl_reverse,
    lists:sum([
        element(1, timer:tc(trim, reverse_tl_reverse, [String]))

Just change the brush name to "python" or "java" or "javascript" and paste in the code of your choice. The CDATA tagging let's you put pretty much any code in there without worrying about entity escaping or other typical annoyances of code blogging.

Very short,

What is the purpose of DI? With dependency injection, objects don't define their dependencies themselves, the dependencies are injected to them as needed.

How does it benefit ? The objects don't need to know where and how to get their dependencies, which results in loose coupling between objects, which makes them a lot easier to test.

How is it implemented ? Usually a container manages the lifecycle of objects and their dependencies based on a configuration file or annotations.

Iterate over the array and do whatever you want with the individual values.

I got this error after freshly cloning a repository. I expected local.properties to be generated automatically, but it wasn't. I was able to generate it by re-importing the Gradle project.

For testing only two values, I'd personally do this:

if x ~= 0 and x ~= 1 then
    print( "X must be equal to 1 or 0" )
    return
end

If you need to test against more than two values, I'd stuff your choices in a table acting like a set, like so:

choices = {[0]=true, [1]=true, [3]=true, [5]=true, [7]=true, [11]=true}

if not choices[x] then
    print("x must be in the first six prime numbers")
    return
end

About the memory layout

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

 \ /
  D

But in the memory layout, you have:

A   A
|   |
B   C
 \ /
  D

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

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

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

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

What could go wrong?

Imagine:

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

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

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

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

Conclusion

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

Another method to construct time zone aware datetime object representing current time:

import datetime
import pytz

pytz.utc.localize( datetime.datetime.utcnow() )  

You can install pytz from PyPI by running:

$ pipenv install pytz

If you are coming here, there is high chance width: min-content or width: max-content can fix your problem. This can force an element to use the smallest or largest space the browser could choose…

This is the modern solution. Here is a small tutorial for that.

There is also fit-content, which often works like min-content, but is more flexible. (But also has worse browser support.)

This is a quite new feature and some browsers do not support it yet, but browser support is growing. See the current browser status here.

1. match_parent

When you set layout width and height as match_parent, it will occupy the complete area that the parent view has, i.e. it will be as big as the parent.

Note : If parent is applied a padding then that space would not be included.

When we create a layout.xml by default we have RelativeLayout as default parent View with android:layout_width="match_parent" and android:layout_height="match_parent" i.e it occupies the complete width and height of the mobile screen.

Also note that padding is applied to all sides,

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

Now lets add a sub-view LinearLayout and sets its layout_width="match_parent" and layout_height="match_parent", the graphical view would display something like this,

match_parent_example

Code

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.code2care.android.togglebuttonexample.MainActivity" >

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="11dp"
android:background="#FFFFEE"
android:orientation="vertical" >

2. fill_parent :

This is same as match_parent, fill_parent was depreciated in API level 8. So if you are using API level 8 or above you must avoid using fill_parent

Lets follow the same steps as we did for match_parent, just instead use fill_parent everywhere.

You would see that there is no difference in behaviour in both fill_parent and match parent.

Something like this (not tested, but should work)

Pass this as parameter in Html:

<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>

And alert the value of the parameter passed into the search function:

function search(e){
  alert(e.value);
}

JOIN t2 ON t1.id=t2.id AND t1.date=t2.date

ACID and BASE are consistency models for RDBMS and NoSQL respectively. ACID transactions are far more pessimistic i.e. they are more worried about data safety. In the NoSQL database world, ACID transactions are less fashionable as some databases have loosened the requirements for immediate consistency, data freshness and accuracy in order to gain other benefits, like scalability and resiliency.

BASE stands for -

• Basic Availability - The database appears to work most of the time.
• Soft-state - Stores don't have to be write-consistent, nor do different replicas have to be mutually consistent all the time.
• Eventual consistency - Stores exhibit consistency at some later point (e.g., lazily at read time).

Therefore BASE relaxes consistency to allow the system to process request even in an inconsistent state.

Example: No one would mind if their tweet were inconsistent within their social network for a short period of time. It is more important to get an immediate response than to have a consistent state of users' information.

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

You can use MySQL variables to do it. Something like this should work (though, it consists of two queries).

SELECT 0 INTO @x;

SELECT itemID, 
       COUNT(*) AS ordercount, 
       (@x:=@x+1) AS rownumber 
FROM orders 
GROUP BY itemID 
ORDER BY ordercount DESC;

If you get the error on this line:

setSupportActionBar(...);

You need to check if your activity is referring to a theme that contains a toolbar. Your application's AppTheme might already contain a toolbar, such as

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

and you are trying to add a second one. If you want to use your application's AppTheme, you need to remove the theme from your activity, in the manifest.xml file.

For example:

<activity
    android:name=".ui.activities.SettingsActivity"
    android:theme="@style/AppTheme1" /> --> remove this theme

Similar to user panchicore's reply, this is what I did on a very simple website. It provides a few variables and makes them available on the template.

SITE_URL would hold a value like example.com
SITE_PROTOCOL would hold a value like http or https
SITE_PROTOCOL_URL would hold a value like http://example.com or https://example.com
SITE_PROTOCOL_RELATIVE_URL would hold a value like //example.com.

module/context_processors.py

from django.conf import settings

def site(request):

    SITE_PROTOCOL_RELATIVE_URL = '//' + settings.SITE_URL

    SITE_PROTOCOL = 'http'
    if request.is_secure():
        SITE_PROTOCOL = 'https'

    SITE_PROTOCOL_URL = SITE_PROTOCOL + '://' + settings.SITE_URL

    return {
        'SITE_URL': settings.SITE_URL,
        'SITE_PROTOCOL': SITE_PROTOCOL,
        'SITE_PROTOCOL_URL': SITE_PROTOCOL_URL,
        'SITE_PROTOCOL_RELATIVE_URL': SITE_PROTOCOL_RELATIVE_URL
    }

settings.py

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    "module.context_processors.site",
    ....
 )

SITE_URL = 'example.com'

Then, on your templates, use them as {{ SITE_URL }}, {{ SITE_PROTOCOL }}, {{ SITE_PROTOCOL_URL }} and {{ SITE_PROTOCOL_RELATIVE_URL }}

Swift 5.3

I think this is very elegant. Kudos at Paul Hudson of "Hacking with Swift" for this solution:

@available (macOS 10.15, * )
extension String {
    subscript(idx: Int) -> String {
        String(self[index(startIndex, offsetBy: idx)])
    }
}

Then to get one character out of the String you simply do:

var string = "Hello, world!"

var firstChar = string[0] // No error, returns "H" as a String

The Connection for controluser as defined in your configuration failed, right after:

$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'you_password';

Use double quote to enclose the quote or escape it.

newTemp = mystring.replace(/"/g, "'");

or

newTemp = mystring.replace(/"/g, '\'');

If you have indexed ID and OrderNo You can use IN: (I hate trading simplicity for obscurity, just to save some cycles):

select * from myTab where ID in(select max(ID) from myTab group by OrderNo);

If you already committed the changes than you would have to revert changes.

If you didn't commit yet, just do a clean checkout git checkout .

Typically you will find these underlying implementation-specific typedefs for gcc in the bits or asm header directory. For me, it's /usr/include/x86_64-linux-gnu/bits/types.h.

You can just grep, or use a preprocessor invocation like that suggested by Quassnoi to see which specific header.

This will work on most modern browsers...apart from IE (browser support). Even though that page lists >= IE9 as supported, my tests didn't agree with that.

You can use the calc() css3 property like so;

.class_name {
    background-position: calc(100% - 10px) 50%;
}

For me this is the cleanest and most logical way to achieve a margin to the right. I also use a fallback of using border-right: 10px solid transparent; for IE.

I started seeing this error after installing the latest command-line tools update (6.1) on Yosemite (10.10.1). In this particular case, a reboot of the system fixed the error (I had not rebooted since the update).

Mentioning this in case anyone with the same problem comes across this page, like I did.

##To check for a particular  string in a file

cd PATH_TO_YOUR_DIRECTORY #Changing directory to your working directory
File=YOUR_FILENAME  
if grep -q STRING_YOU_ARE_CHECKING_FOR "$File"; ##note the space after the string you are searching for
then
echo "Hooray!!It's available"
else
echo "Oops!!Not available"
fi

In date '?', the '?' is a literal string with value ?, not a parameter placeholder, so your query does not have any parameters. The date is a shorthand cast from (literal) string to date. You need to replace date '?' with ? to actually have a parameter.

Also if you know it is a date, then use setDate(..) and not setString(..) to set the parameter.

These work for me and fit the WebView to screen width:

// get from xml, with all size set "fill_parent"  
webView = (WebView) findViewById(R.id.webview_in_layout);  
// fit the width of screen
webView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); 
// remove a weird white line on the right size
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

Ruby's Hash#compact, Hash#compact! and Hash#delete_if! do not work on nested nil, empty? and/or blank? values. Note that the latter two methods are destructive, and that all nil, "", false, [] and {} values are counted as blank?.

Hash#compact and Hash#compact! are only available in Rails, or Ruby version 2.4.0 and above.

Here's a non-destructive solution that removes all empty arrays, hashes, strings and nil values, while keeping all false values:

(blank? can be replaced with nil? or empty? as needed.)

def remove_blank_values(hash)
  hash.each_with_object({}) do |(k, v), new_hash|
    unless v.blank? && v != false
      v.is_a?(Hash) ? new_hash[k] = remove_blank_values(v) : new_hash[k] = v
    end
  end
end

A destructive version:

def remove_blank_values!(hash)
  hash.each do |k, v|
    if v.blank? && v != false
      hash.delete(k)
    elsif v.is_a?(Hash)
      hash[k] = remove_blank_values!(v)
    end
  end
end

Or, if you want to add both versions as instance methods on the Hash class:

class Hash
  def remove_blank_values
    self.each_with_object({}) do |(k, v), new_hash|
      unless v.blank? && v != false
        v.is_a?(Hash) ? new_hash[k] = v.remove_blank_values : new_hash[k] = v
      end
    end
  end

  def remove_blank_values!
    self.each_pair do |k, v|
      if v.blank? && v != false
        self.delete(k)
      elsif v.is_a?(Hash)
        v.remove_blank_values!
      end
    end
  end
end

Other options:

• Replace v.blank? && v != false with v.nil? || v == "" to strictly remove empty strings and nil values
• Replace v.blank? && v != false with v.nil? to strictly remove nil values
• Etc.

EDITED 2017/03/15 to keep false values and present other options

It is OK, but at the same time can cause some browsers to become slow.

http://webdesignfan.com/yslow-tutorial-part-2-of-3-reducing-server-calls/

My advice is use <a href="#"></a>

If you're using JQuery remember to also use:

.click(function(event){
    event.preventDefault();
    // Click code here...
});

I needed an overload for:

public ActionResult Index(string i);
public ActionResult Index(int groupId, int itemId);

There were few enough arguments where I ended up doing this:

public ActionResult Index(string i, int? groupId, int? itemId)
{
    if (!string.IsNullOrWhitespace(i))
    {
        // parse i for the id
    }
    else if (groupId.HasValue && itemId.HasValue)
    {
        // use groupId and itemId for the id
    }
}

It's not a perfect solution, especially if you have a lot of arguments, but it works well for me.

It would be neater to capture the error file thus:

ERROR=$(</tmp/Error)

The shell recognizes this and doesn't have to run 'cat' to get the data.

The bigger question is hard. I don't think there's an easy way to do it. You'd have to build the entire pipeline into the sub-shell, eventually sending its final standard output to a file, so that you can redirect the errors to standard output.

ERROR=$( { ./useless.sh | sed s/Output/Useless/ > outfile; } 2>&1 )

Note that the semi-colon is needed (in classic shells - Bourne, Korn - for sure; probably in Bash too). The '{}' does I/O redirection over the enclosed commands. As written, it would capture errors from sed too.

WARNING: Formally untested code - use at own risk.

This seems to have changed in the latest version of React Native when using refs to calculate.

Declare refs this way.

  <View
    ref={(image) => {
    this._image = image
  }}>

And find the value this way.

  _measure = () => {
    this._image._component.measure((width, height, px, py, fx, fy) => {
      const location = {
        fx: fx,
        fy: fy,
        px: px,
        py: py,
        width: width,
        height: height
      }
      console.log(location)
    })
  }

Use curly brackets and put all the attributes you want to add inside

Example:

$('#objId').attr({
    target: 'nw',
    title: 'Opens in a new window'
});

For super correctness, you should use:

Rails.root.join('foo','bar')

which will allow your app to work on platforms where / is not the directory separator, should anyone try and run it on one.

Yet another variant:

Date.prototype.isPrototypeOf(myDateObject)

I came to this post while researching for a similar need, but i felt cloning solution that is so popular, to be too raw and takes my focus away from the functionality.

I found an article in react documents Higher Order Components

Here is my sample:

import React from 'react';

const withForm = (ViewComponent) => {
    return (props) => {

        const myParam = "Custom param";

        return (
            <>
                <div style={{border:"2px solid black", margin:"10px"}}>
                    <div>this is poc form</div>
                    <div>
                        <ViewComponent myParam={myParam} {...props}></ViewComponent>
                    </div>
                </div>
            </>
        )
    }
}

export default withForm;


const pocQuickView = (props) => {
    return (
        <div style={{border:"1px solid grey"}}>
            <div>this is poc quick view and it is meant to show when mouse hovers over a link</div>
        </div>
    )
}

export default withForm(pocQuickView);

For me i found a flexible solution in implementing the pattern of Higher Order Components.

Of course it depends on the functionality, but it is good if someone else is looking for a similar requirement, it is much better than being dependent on raw level react code like cloning.

Other pattern that i actively use is the container pattern. do read about it, there are many articles out there.

another way, will also work on MySQL and PostgreSQL

select TABLE_NAME from INFORMATION_SCHEMA.TABLES
where TABLE_TYPE = 'BASE TABLE'

It is impossible to do it in Eclipse in generic way right now, but it can be changed given with basic Java knowledge and some free time to add basic support for this https://bugs.eclipse.org/bugs/show_bug.cgi?id=180349

The dependent issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=311173

You need to use the target selector.

Here is a fiddle with another example: http://jsfiddle.net/YYPKM/3/

First of all this code snippet

char *addr=NULL;
strcpy(addr,retstring().c_str());

is invalid because you did not allocate memory where you are going to copy retstring().c_str().

As for the error message then it is clear enough. The type of expression data.str().c_str() is const char * but the third parameter of the function is declared as char *. You may not assign an object of type const char * to an object of type char *. Either the function should define the third parameter as const char * if it does not change the object pointed by the third parameter or you may not pass argument of type const char *.

you must change Territory and click on save, after one minute your app will be available. No need to Remove from sale

It's not a direct answer to the question, however I would suggest in most cases to simply set multiple classes to each element:

<div class="myclass one"></div>
<div class="myclass two></div>
<div class="myclass three"></div>

In this way you can set rules for all myclass elements and then more specific rules for one, two and three.

.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

I think you should give the data types of the column as NUMERIC or DOUBLE or FLOAT or REAL

Read http://sqlite.org/datatype3.html to more info.

This one makes sure you have no more than three valid pairs:

(([a-fA-F]|[0-9]){2}){3}

Any more or less than three pairs of valid characters fail to match.

Running the command prompt or Powershell ISE as an administrator fixed this for me.

create some member variables in your activity like

YourAsyncTask mTask;
Dialog mDialog;

use these for your dialog and task;

in onPause() simply call

if(mTask!=null) mTask.cancel(); 
if(mDialog!=null) mDialog.dismiss();

I had a similar issue, but it didn't help to add extension=mysql.so in my php.ini. It turned out that the mysql.so file was not in my extension folder nor anywhere else on my machine. Solved this by downloading the php source and building the extension manually and then copying it into the extension folder.

To count the number of a specific filetype in a folder. The example is to count mp3 files on F: drive.

Tested in 6.2.3, but should work >4.

The simpliest solution is:

dialog.show(); //Only after .show() was called
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(neededColor);
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(neededColor);

Get all views of a view plus its children recursively in Kotlin:

private fun View.getAllViews(): List<View> {
    if (this !is ViewGroup || childCount == 0) return listOf(this)

    return children
            .toList()
            .flatMap { it.getAllViews() }
            .plus(this as View)
}

allocated non-array memory at 0x3e39e0 (20 bytes)
releasing     array memory at 0x22ff38

As you can see, you are trying to release with the wrong form of delete (non-array vs. array), and the pointer 0x22ff38 has never been returned by a call to new. The second version shows the correct output:

[allocations omitted for brevity]
releasing non-array memory at 0x3e38f0
releasing non-array memory at 0x3e3920
releasing non-array memory at 0x3e3950
releasing non-array memory at 0x3e3980
releasing non-array memory at 0x3e39b0
releasing non-array memory at 0x3e39e0

Anyway, I prefer a design where manually implementing the destructor is not necessary to begin with.

#include <array>
#include <memory>

class Foo
{
    std::array<std::shared_ptr<Monster>, 6> monsters;

    Foo()
    {
        for (int i = 0; i < 6; ++i)
        {
            monsters[i].reset(new Monster());
        }
    }

    virtual ~Foo()
    {
        // nothing to do manually
    }
};

I don't believe this can be done "out of the box" in wordpress; The closest thing is storing media uploads by date-based subfolders, as per the option Organize my uploads into month- and year-based folders on the media settings screen.

Next best might be to create a "dummy" page hierarchy that serves as your folder tree, and then attach your images to these. This would give you a logical grouping, which could exist in relative isolation from your actual page or post hierarchy. But of course this won't give you the files organised like this in the file system, eg you couldn't of course FTP to this structure.

Otherwise I think you'll need to find a plugin or write something yourself to handle this.

Some plugins I found after a quick google for "wordpress plugin media folders":

• http://wordpress.org/extend/plugins/media-file-manager/
• http://wordpress.org/extend/plugins/media-folders/

While these might not be precisely what you want, they might give you clues/direction towards implementing something yourself. (Although that first one looks promising.)

Just FYI at least one similar question has been asked over on Wordpress.stackexchange:

https://wordpress.stackexchange.com/questions/13030/media-library-plugins-for-better-file-management

It might pay to have a good hunt about over there for something more substantial . Good luck!

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

<script type="text/javascript" >
    do your codes here  it will work..
    type="text/javascript" is important for jquery 
<script>

The way without re-inserting all entries into the new map should be the fastest it won't because HashMap.clone internally performs rehash as well.

Map<String, Column> newColumnMap = originalColumnMap.clone();
newColumnMap.replaceAll((s, c) -> new Column(c));

Wrap your two+ function calls in another function/method. Here are a couple variants of that idea:

1) Separate method

var Test = React.createClass({
   onClick: function(event){
      func1();
      func2();
   },
   render: function(){
      return (
         <a href="#" onClick={this.onClick}>Test Link</a>
      );
   }
});

or with ES6 classes:

class Test extends React.Component {
   onClick(event) {
      func1();
      func2();
   }
   render() {
      return (
         <a href="#" onClick={this.onClick}>Test Link</a>
      );
   }
}

2) Inline

<a href="#" onClick={function(event){ func1(); func2()}}>Test Link</a>

or ES6 equivalent:

<a href="#" onClick={() => { func1(); func2();}}>Test Link</a>

Take the attribute

app:layout_behavior="@string/appbar_scrolling_view_behavior"

off the RecyclerView and put it on the FrameLayout that you are trying to show under the Toolbar.

I've found that one important thing the scrolling view behavior does is to layout the component below the toolbar. Because the FrameLayout has a descendant that will scroll (RecyclerView), the CoordinatorLayout will get those scrolling events for moving the Toolbar.

One other thing to be aware of: That layout behavior will cause the FrameLayout height to be sized as if the Toolbar is already scrolled, and with the Toolbar fully displayed the entire view is simply pushed down so that the bottom of the view is below the bottom of the CoordinatorLayout.

This was a surprise to me. I was expecting the view to be dynamically resized as the toolbar is scrolled up and down. So if you have a scrolling component with a fixed component at the bottom of your view, you won't see that bottom component until you have fully scrolled the Toolbar.

So when I wanted to anchor a button at the bottom of the UI, I worked around this by putting the button at the bottom of the CoordinatorLayout (android:layout_gravity="bottom") and adding a bottom margin equal to the button's height to the view beneath the toolbar.

Use unshift. It's like push, except it adds elements to the beginning of the array instead of the end.

• unshift/push - add an element to the beginning/end of an array
• shift/pop - remove and return the first/last element of an array

A simple diagram...

   unshift -> array <- push
   shift   <- array -> pop
 

and chart:

          add  remove  start  end
   push    X                   X
    pop           X            X
unshift    X             X
  shift           X      X

Check out the MDN Array documentation. Virtually every language that has the ability to push/pop elements from an array will also have the ability to unshift/shift (sometimes called push_front/pop_front) elements, you should never have to implement these yourself.

As pointed out in the comments, if you want to avoid mutating your original array, you can use concat, which concatenates two or more arrays together. You can use this to functionally push a single element onto the front or back of an existing array; to do so, you need to turn the new element into a single element array:

const array = [3, 2, 1]

const newFirstElement = 4

const newArray = [newFirstElement].concat(array) // [ 4, 3, 2, 1 ]

console.log(newArray);

concat can also append items. The arguments to concat can be of any type; they are implicitly wrapped in a single-element array, if they are not already an array:

const array = [3, 2, 1]

const newLastElement = 0

// Both of these lines are equivalent:
const newArray1 = array.concat(newLastElement) // [ 3, 2, 1, 0 ]
const newArray2 = array.concat([newLastElement]) // [ 3, 2, 1, 0 ]

console.log(newArray1);
console.log(newArray2);

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

$myFile = "4-24-11.txt";
$lines = file($myFile);//file in to an array
echo $lines[1]; //line 2

file — Reads entire file into an array

Use double brackets...

if [[ expression ]]

You could do an ajax call.

That way, you would be able to populate the POST array yourself through the ajax 'data: ' parameter

var params = {
  url: window.location.pathname,
  time: new Date().getTime(), 
};


$.ajax({
  method: "POST",
  url: "your/script.php",
  data: params
});

When use them, I make an exhaustive cheatsheet of their methods for your reference:

class ContainerMethods:
    def __init__(self):
        self.list_methods_11 = {
                    'Add':{'append','extend','insert'},
                    'Subtract':{'pop','remove'},
                    'Sort':{'reverse', 'sort'},
                    'Search':{'count', 'index'},
                    'Entire':{'clear','copy'},
                            }
        self.tuple_methods_2 = {'Search':'count','index'}

        self.dict_methods_11 = {
                    'Views':{'keys', 'values', 'items'},
                    'Add':{'update'},
                    'Subtract':{'pop', 'popitem',},
                    'Extract':{'get','setdefault',},
                    'Entire':{ 'clear', 'copy','fromkeys'},
                            }
        self.set_methods_17 ={
                    'Add':{['add', 'update'],['difference_update','symmetric_difference_update','intersection_update']},
                    'Subtract':{'pop', 'remove','discard'},
                    'Relation':{'isdisjoint', 'issubset', 'issuperset'},
                    'operation':{'union' 'intersection','difference', 'symmetric_difference'}
                    'Entire':{'clear', 'copy'}}

You should install the PHP 5 library for Apache.

For Debian and Ubuntu:

apt-get install libapache2-mod-php5

And restart the Apache:

service apache2 restart

as suggested in other posts, probably you don't have any user defined. it's not advisable to manually edit the configuration files. you should use the add-user (.sh or .cmd) utility as explained in https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6/html/Installation_Guide/chap-Getting_Started_with_JBoss_Enterprise_Application_Platform_6.html#Add_the_Initial_User_for_the_Management_Interfaces

Stop using the TEXT data type in SQL Server!

It's been deprecated since the 2005 version. Use VARCHAR(MAX) instead, if you need more than 8000 characters.

The TEXT data type doesn't support the normal string functions, while VARCHAR(MAX) does - your statement would work just fine, if you'd be using just VARCHAR types.

Not every jar file is executable.

Now, you need to import the classes, which are there under the jar, in your java file. For example,

import org.xml.sax.SAXException;

If you are working on an IDE, then you should refer its documentation. Or at least specify which one you are using here in this thread. It would definitely enable us to help you further.

And if you are not using any IDE, then please look at javac -cp option. However, it's much better idea to package your program in a jar file, and include all the required jars within that. Then, in order to execute your jar, like,

java -jar my_program.jar

you should have a META-INF/MANIFEST.MF file in your jar. See here, for how-to.

First you need to specify in the Headers the Content-Type, for example, it can be application/json.

If you set application/json content type, then you need to send a json.

So in the body of your request you will send not form-data, not x-www-for-urlencoded but a raw json, for example {"Username": "user", "Password": "pass"}

You can adapt the example to various content types, including what you want to send.

You can use a tool like Postman or curl to play with this.

You need to input:

$ git pull
$ git fetch 
$ git merge

If you use a git push origin master --force, you will have a big problem.

You may try with below query :

INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );

To view the result of it:

SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss') 
FROM errortable 
    WHERE table1id = 1083;

do it like this

objArrayy.sort(function(a, b){
 var nameA=a.name.toLowerCase(), nameB=b.name.toLowerCase()
 if (nameA < nameB) //sort string ascending
  return -1
 if (nameA > nameB)
  return 1
 return 0 //default return value (no sorting)
});
console.log(objArray)

This is a select statement, so each branch of the case must return something. If you want to perform actions, just use an if.

Here is the latest sample of Google's geocode Web Service

https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_API_KEY

Simply change the YOUR_API_KEY to the API key you get from Google Geocoding API

P/S: Geocoding API is under Places NOT Maps ;)

I found that both methods were very helpful in coming up with a working solution. Here is my composite version, that is pixel independent and allows you to have some square corners with the rest of the corners having the same radius (which is the usual use case). With thanks to both of the solutions above:

public static Bitmap getRoundedCornerBitmap(Context context, Bitmap input, int pixels , int w , int h , boolean squareTL, boolean squareTR, boolean squareBL, boolean squareBR  ) {

    Bitmap output = Bitmap.createBitmap(w, h, Config.ARGB_8888);
    Canvas canvas = new Canvas(output);
    final float densityMultiplier = context.getResources().getDisplayMetrics().density;

    final int color = 0xff424242;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, w, h);
    final RectF rectF = new RectF(rect);

    //make sure that our rounded corner is scaled appropriately
    final float roundPx = pixels*densityMultiplier;

    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawRoundRect(rectF, roundPx, roundPx, paint);


    //draw rectangles over the corners we want to be square
    if (squareTL ){
        canvas.drawRect(0, h/2, w/2, h, paint);
    }
    if (squareTR ){
        canvas.drawRect(w/2, h/2, w, h, paint);
    }
    if (squareBL ){
        canvas.drawRect(0, 0, w/2, h/2, paint);
    }
    if (squareBR ){
        canvas.drawRect(w/2, 0, w, h/2, paint);
    }


    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(input, 0,0, paint);

    return output;
}

Also, I overrode ImageView to put this in so I could define it in xml. You may want to add in some of the logic that the super call makes here, but I've commented it as it's not helpful in my case.

    @Override
protected void onDraw(Canvas canvas) {
    //super.onDraw(canvas);
        Drawable drawable = getDrawable();

        Bitmap b =  ((BitmapDrawable)drawable).getBitmap() ;
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();


        Bitmap roundBitmap =  CropImageView.getRoundedCornerBitmap( getContext(), bitmap,10 , w, h , true, false,true, false);
        canvas.drawBitmap(roundBitmap, 0,0 , null);
}

Hope this helps!

Drop the hash - that's for identifying the id attribute.

Wrap your formula with IFERROR.

=IFERROR(yourformula)

#include <QFile>
#include <QCoreApplication>
#include <QTextStream>

int main(int argc, char *argv[])
{
    // Create a new file     
    QFile file("out.txt");
    file.open(QIODevice::WriteOnly | QIODevice::Text);
    QTextStream out(&file);
    out << "This file is generated by Qt\n";

    // optional, as QFile destructor will already do it:
    file.close(); 

    //this would normally start the event loop, but is not needed for this
    //minimal example:
    //return app.exec();

    return 0;
}

//An example of implementation :
// we set the score of one player to a value
[Game getCurrent].scorePlayer1 = [NSNumber numberWithInteger:1];
// We copy the value in a NSNumber
NSNumber *aNumber = [Game getCurrent].scorePlayer1;
// Conversion of the NSNumber aNumber to a String with stringValue
NSString *StringScorePlayer1 = [aNumber stringValue];

This is very compact:

w['female'][w['female'] == 'female']=1
w['female'][w['female'] == 'male']=0

Another good one:

w['female'] = w['female'].replace(regex='female', value=1)
w['female'] = w['female'].replace(regex='male', value=0)

You could install forever using npm like this:

sudo npm install -g forever

And then start your application with:

forever server.js

Or as a service:

forever start server.js

Forever restarts your app when it crashes or stops for some reason. To restrict restarts to 5 you could use:

forever -m5 server.js

To list all running processes:

forever list

Note the integer in the brackets and use it as following to stop a process:

forever stop 0

Restarting a running process goes:

forever restart 0

If you're working on your application file, you can use the -w parameter to restart automatically whenever your server.js file changes:

forever -w server.js

I installed pip3 using

python3.7 -m pip install pip

But upon using pip3 to install other dependencies, it was using python3.6.
You can check the by typing pip3 --version

Hence, I used pip3 like this (stated in one of the above answers):

python3.7 -m pip install <module>

or use it like this:

python3.7 -m pip install -r requirements.txt

I made a bash alias for later use in ~/.bashrc file as alias pip3='python3.7 -m pip'. If you use alias, don't forget to source ~/.bashrc after making the changes and saving it.

There's a Py library that has a module that facilitates access to Json-like dictionary key-values as attributes: https://github.com/asuiu/pyxtension You can use it as:

j = Json('{"lat":444, "lon":555}')
j.lat + ' ' + j.lon

The whole reason for having kubernetes is so it manages the containers for you so you don't have to care so much about the lifecyle of the containers in the pod.

Since you have a deployment setup that uses replica set. You can delete the pod using kubectl delete pod test-1495806908-xn5jn and kubernetes will manage the creation of a new pod with the 2 containers without any downtime. Trying to manually restart single containers in pods negates the whole benefits of kubernetes.

Good Example can be when incase of writing it after the end of your query if you have joins or where close :

 select 'idPago','fecha','lead','idAlumno','idTipoPago','idGpo'
 union all
(select id_control_pagos, fecha, lead, id_alumno, id_concepto_pago, id_Gpo,id_Taller,
id_docente, Pagoimporte, NoFactura, FacturaImporte, Mensualidad_No, FormaPago,
Observaciones from control_pagos
into outfile 'c:\\data.csv' 
FIELDS TERMINATED BY ',' 
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n');

As said by jensgram, IE6 does not support attribute selector. You could add a class="disabled" to select the disabled inputs so that this can work in IE6.

For proxy_upstream timeout, I tried the above setting but these didn't work.

Setting resolver_timeout worked for me, knowing it was taking 30s to produce the upstream timeout message. E.g. me.atwibble.com could not be resolved (110: Operation timed out).

http://nginx.org/en/docs/http/ngx_http_core_module.html#resolver_timeout

Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.

Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).

Awhile ago, I put together a package for doing what you want, and more. (I needed it for a utility I was writing). It uses the ASM library. You can use reflection, but ASM turned out to perform better.

I put my package in an open source library I have on my web site. The library is here: http://software.clapper.org/javautil/. You want to start with the with ClassFinder class.

The utility I wrote it for is an RSS reader that I still use every day, so the code does tend to get exercised. I use ClassFinder to support a plug-in API in the RSS reader; on startup, it looks in a couple directory trees for jars and class files containing classes that implement a certain interface. It's a lot faster than you might expect.

The library is BSD-licensed, so you can safely bundle it with your code. Source is available.

If that's useful to you, help yourself.

Update: If you're using Scala, you might find this library to be more Scala-friendly.

Yes, below is a link of docs.Oracle where you can find complete list of escape characters in Java.

Escape characters are always preceded with "\" and used to perform some specific task like go to next line etc.

For more Details on Escape Character Refer following link:

I noticed some of the answers were not triggering the HTML5 required attribute (as stuff was being executed on the action of clicking rather than the action of form send, causing to bypass it when the inputs were empty):

1. Have a <form id='xform'></form> with some inputs with the required attribute and place a <input type='submit'> at the end.
2. A confirmation input where typing "ok" is expected <input type='text' name='xconf' value='' required>
3. Add a modal_1_confirm to your html (to confirm the form of sending).
4. (on modal_1_confirm) add the id modal_1_accept to the accept button.
5. Add a second modal_2_errMsg to your html (to display form validation errors).
6. (on modal_2_errMsg) add the id modal_2_accept to the accept button.
7. (on modal_2_errMsg) add the id m2_Txt to the displayed text holder.

8. The JS to intercept before the form is sent:

   $("#xform").submit(function(e){
       var msg, conf, preventSend;
   
       if($("#xform").attr("data-send")!=="ready"){
           msg="Error."; //default error msg
           preventSend=false;
   
           conf=$("[name='xconf']").val().toLowerCase().replace(/^"|"$/g, "");
   
           if(conf===""){
               msg="The field is empty.";
               preventSend=true;
           }else if(conf!=="ok"){
               msg="You didn't write \"ok\" correctly.";
               preventSend=true;
           }
   
           if(preventSend){ //validation failed, show the error
               $("#m2_Txt").html(msg); //displayed text on modal_2_errMsg
               $("#modal_2_errMsg").modal("show");
           }else{ //validation passed, now let's confirm the action
               $("#modal_1_confirm").modal("show");
           }
   
           e.preventDefault();
           return false;
       }
   });
   

`9. Also some stuff when clicking the Buttons from the modals:

$("#modal_1_accept").click(function(){
    $("#modal_1_confirm").modal("hide");
    $("#xform").attr("data-send", "ready").submit();
});

$("#modal_2_accept").click(function(){
    $("#modal_2_errMsg").modal("hide");
});

Important Note: So just be careful if you add an extra way to show the modal, as simply clicking the accept button $("#modal_1_accept") will assume the validation passed and it will add the "ready" attribute:

• The reasoning for this is that $("#modal_1_confirm").modal("show"); is shown only when it passed the validation, so clicking $("#modal_1_accept") should be unreachable without first getting the form validated.

Just change the

DATEDIFF(Hour,InTime, [TimeOut]) TotalHours

part to

CONCAT((DATEDIFF(Minute,InTime,[TimeOut])/60),':',
       (DATEDIFF(Minute,InTime,[TimeOut])%60)) TotalHours 

The /60 gives you hours, the %60 gives you the remaining minutes, and CONCAT lets you put a colon between them.

I know it's an old question, but I came across it and thought it might help if someone else comes across it.

Hope you don't mind but I cobbled together all the helpful stuff, from above, and came up with a complete class ready for testing...

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;

I found this configuration in my web.config which was for a New Web Site... created in Visual Studio (as opposed to a New Project...). Since the question states a ASP.NET MVC application, not as relevant, but still an option.

<system.webServer>
  <httpProtocol>
    <customHeaders>
      <clear />
      <remove name="X-Powered-By" />
    </customHeaders>
   </httpProtocol>
</system.webServer>

Update: Also, Troy Hunt has an article titled Shhh… don’t let your response headers talk too loudly with detailed steps on removing these headers as well as a link to his ASafaWeb tool for scanning for them and other security configurations.

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");
