1. Select cell B3 and click the Conditional Formatting button in the ribbon and choose "New Rule".
2. Select "Use a formula to determine which cells to format"
3. Enter the formula: =IF(B2="X",IF(B3="Y", TRUE, FALSE),FALSE), and choose to fill green when this is true
4. Create another rule and enter the formula =IF(B2="X",IF(B3="W", TRUE, FALSE),FALSE) and choose to fill red when this is true.

More details - conditional formatting with a formula applies the format when the formula evaluates to TRUE. You can use a compound IF formula to return true or false based on the values of any cells.

I know, I am late but here is the correct way of doing it. using base64. This technique will convert the array to string.

import base64
import numpy as np
random_array = np.random.randn(32,32)
string_repr = base64.binascii.b2a_base64(random_array).decode("ascii")
array = np.frombuffer(base64.binascii.a2b_base64(string_repr.encode("ascii"))) 

For array to string

Convert binary data to a line of ASCII characters in base64 coding and decode to ASCII to get string repr.

For string to array

First, encode the string in ASCII format then Convert a block of base64 data back to binary and return the binary data.

As well as Amateras you could try Web Tools Project or Aptana. Although they will both give you way more than just a jsp editor.

Edit 2010/10/26 (comment from Simon Gibbs):

The Web Tools Project JSP editor is in the "Web Page Editor (Optional)" project.

Edit 2016/08/16 (extended comment from Dan Carter):

From Kepler (Eclipse 4.3.x) on, this is called "JSF Tools - Web Page Editor".

For only one line, you need

...
<View android:id="@+id/primerdivisor"
android:layout_height="2dp"
android:layout_width="fill_parent"
android:background="#ffffff" /> 
...

UPDATE

Now we need to use Custom Targets

SAMPLE CODE

    Glide.with(mContext)
            .asBitmap()
            .load("url")
            .into(new CustomTarget<Bitmap>() {
                @Override
                public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {

                }

                @Override
                public void onLoadCleared(@Nullable Drawable placeholder) {
                }
            });

How does one use glide to download an image into a bitmap?

The above all answer are correct but outdated

because in new version of Glide implementation 'com.github.bumptech.glide:glide:4.8.0'

You will find below error in code

• The .asBitmap() is not available in glide:4.8.0

• SimpleTarget<Bitmap> is deprecated

Here is solution

    }
}

@@RowCount will give you the number of records affected by a SQL Statement.

The @@RowCount works only if you issue it immediately afterwards. So if you are trapping errors, you have to do it on the same line. If you split it up, you will miss out on whichever one you put second.

SELECT @NumRowsChanged = @@ROWCOUNT, @ErrorCode = @@ERROR

If you have multiple statements, you will have to capture the number of rows affected for each one and add them up.

SELECT @NumRowsChanged = @NumRowsChanged  + @@ROWCOUNT, @ErrorCode = @@ERROR

Number(new Date(2010, 6, 26))

Works the same way as things above. If you need seconds don't forget to / 1000

The best solution above faces a problem when using the same associative keys, array_merge() will merge array elements together when they have the same NON-NUMBER key, so it is not suitable for the following case

$a1=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow");
$a2=array("c"=>"red","d"=>"black","e"=>"green");

If you are able output your value to the keys of your arrays instead (e.g ->pluck('name', 'id')->toArray() in Eloquent), you can use the following merge method instead

array_keys(array_merge($a1, $a2))

Basically what the code does is it utilized the behavior of array_merge() to get rid of duplicated keys and return you a new array with keys as array elements, hope it helps

Use alternative HashMap implementation (Trove). Standard Java HashMap has >12x memory overhead. One can read details here.

I would use TreeMap, which implements SortedMap. It is designed exactly for that.

Example:

Map<Integer, String> map = new TreeMap<Integer, String>();

// Add Items to the TreeMap
map.put(1, "One");
map.put(2, "Two");
map.put(3, "Three");

// Iterate over them
for (Map.Entry<Integer, String> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " => " + entry.getValue());
}

See the Java tutorial page for SortedMap.
And here a list of tutorials related to TreeMap.

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

You are writing to your memory stream twice, also you are not disposing the stream after use. You are also asking the image decoder to apply embedded color correction.

Try this instead:

using (var ms = new MemoryStream(byteArrayIn))
{
    return Image.FromStream(ms);
}

I tried using IFTTT and many other services but all were doing things or post from Instagram to another platform not to Instagram. I read more to found Instagram does not provide any such API as of now.

Using blue stack is again involving heavy installation and doing things manually only.

However, you can use your Google Chrome on the desktop version to make a post on Instagram. It needs a bit tweak.

1. Open your chrome and browse Instagram.com
2. Go to inspect element by right clicking on chrome.
3. From top right corener menu drop down on developer tools, select more tool.
4. Further select network conditions.
5. In the network selection section, see the second section there named user agent.
6. Uncheck select automatically, and select chrome for Android from the list of given user agent.
7. Refresh your Instagram.com page.

You will notice a change in UI and the option to make a post on Instagram. Your life is now easy. Let me know an easier way if you can find any.

I wrote on https://www.inteligentcomp.com/2018/11/how-to-upload-to-instagram-from-pc-mac.html about it.

Working Screenshot

The number type has a step value controlling which numbers are valid (along with max and min), which defaults to 1. This value is also used by implementations for the stepper buttons (i.e. pressing up increases by step).

Simply change this value to whatever is appropriate. For money, two decimal places are probably expected:

<input type="number" step="0.01">

(I'd also set min=0 if it can only be positive)

If you'd prefer to allow any number of decimal places, you can use step="any" (though for currencies, I'd recommend sticking to 0.01). In Chrome & Firefox, the stepper buttons will increment / decrement by 1 when using any. (thanks to Michal Stefanow's answer for pointing out any, and see the relevant spec here)

Here's a playground showing how various steps affect various input types:

<form>_x000D_
  <input type=number step=1 /> Step 1 (default)<br />_x000D_
  <input type=number step=0.01 /> Step 0.01<br />_x000D_
  <input type=number step=any /> Step any<br />_x000D_
  <input type=range step=20 /> Step 20<br />_x000D_
  <input type=datetime-local step=60 /> Step 60 (default)<br />_x000D_
  <input type=datetime-local step=1 /> Step 1<br />_x000D_
  <input type=datetime-local step=any /> Step any<br />_x000D_
  <input type=datetime-local step=0.001 /> Step 0.001<br />_x000D_
  <input type=datetime-local step=3600 /> Step 3600 (1 hour)<br />_x000D_
  <input type=datetime-local step=86400 /> Step 86400 (1 day)<br />_x000D_
  <input type=datetime-local step=70 /> Step 70 (1 min, 10 sec)<br />_x000D_
</form>

As usual, I'll add a quick note: remember that client-side validation is just a convenience to the user. You must also validate on the server-side!

I made some small changes to Alex McKay's function/usage that I think make it a little easier to follow why it works and also adheres to the no-use-before-define rule.

First, define this function to use:

const getKeyValue = function<T extends object, U extends keyof T> (obj: T, key: U) { return obj[key] }

In the way I've written it, the generic for the function lists the object first, then the property on the object second (these can occur in any order, but if you specify U extends key of T before T extends object you break the no-use-before-define rule, and also it just makes sense to have the object first and its' property second. Finally, I've used the more common function syntax instead of the arrow operators (=>).

Anyways, with those modifications you can just use it like this:

interface User {
  name: string;
  age: number;
}

const user: User = {
  name: "John Smith",
  age: 20
};

getKeyValue(user, "name")

Which, again, I find to be a bit more readable.

As suggested by @EboMike I saved the bitmap in a file named myImage in the internal storage of my application not accessible my other apps. Here's the code of that part:

public String createImageFromBitmap(Bitmap bitmap) {
    String fileName = "myImage";//no .png or .jpg needed
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
        fo.write(bytes.toByteArray());
        // remember close file output
        fo.close();
    } catch (Exception e) {
        e.printStackTrace();
        fileName = null;
    }
    return fileName;
}

Then in the next activity you can decode this file myImage to a bitmap using following code:

Bitmap bitmap = BitmapFactory.decodeStream(context
                    .openFileInput("myImage"));//here context can be anything like getActivity() for fragment, this or MainActivity.this

Note A lot of checking for null and scaling bitmap's is ommited.

Regular Expressions will be more optimal for a lot of people because of word boundaries \b or similar devices. Word boundaries occur when any of 0-9, a-z, A-Z, _ are on that side of the next match, or when an alphanumeric character connects to line or string end or beginning.

if (location.href.match(/(?:\b|_)franky(?:\b|_)))

If you use if(window.location.href.indexOf("sam"), you'll get matches for flotsam and same, among other words. tom would match tomato and tomorrow, without regex.

Making it case-sensitive is as simple as removing the i.

Further, adding other filters is as easy as

if (location.href.match(/(?:\b|_)(?:franky|bob|billy|john|steve)(?:\b|_)/i))

Let's talk about (?:\b|_). RegEx typically defines _ as a word character so it doesn't cause a word boundary. We use this (?:\b|_) to deal with this. To see if it either finds \b or _ on either side of the string.

Other languages may need to use something like

if (location.href.match(/([^\wxxx]|^)(?:franky|bob|billy|john|steve)([^\wxxx]|$)/i))
//where xxx is a character representation (range or literal) of your language's alphanumeric characters.

All of this is easier than saying

var x = location.href // just used to shorten the code
x.indexOf("-sam-") || x.indexOf("-sam.") || x.indexOf(" sam,") || x.indexOf("/sam")...
// and other comparisons to see if the url ends with it 
// more for other filters like frank and billy

^{Other languages' flavors of Regular Expressions support \p{L} but javascript does not, which would make the task of detecting foreign characters much easier. Something like [^\p{L}](filters|in|any|alphabet)[^\p{L}]}

I know this is an old post and that it wants an answer for .NET 1.1 but there's already a very good answer for that. I thought it would be good to have an answer for those people who land on this post that may have a more recent version of the .Net framework, such as myself when I went looking for an answer to the same question.

In those cases there is an even simpler way to write the contents of a StringBuilder to a text file. It can be done with one line of code. It may not be the most efficient but that wasn't really the question now was it.

System.IO.File.WriteAllText(@"C:\MyDir\MyNewTextFile.txt",sbMyStringBuilder.ToString());

it is just a sample to avoid max recursion error. we have to use option (maxrecursion 365); or option (maxrecursion 0);

DECLARE @STARTDATE datetime; 
DECLARE @EntDt datetime; 
set @STARTDATE = '01/01/2009';  
set @EntDt = '12/31/2009'; 
declare @dcnt int; 
;with DateList as   
 (   
    select @STARTDATE DateValue   
    union all   
    select DateValue + 1 from    DateList      
    where   DateValue + 1 < convert(VARCHAR(15),@EntDt,101)   
 )   
  select count(*) as DayCnt from (   
  select DateValue,DATENAME(WEEKDAY, DateValue ) as WEEKDAY from DateList
  where DATENAME(WEEKDAY, DateValue ) not IN ( 'Saturday','Sunday' )     
  )a
option (maxrecursion 365);

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

I really love this excerpt from 10 Things I hate about git (it gives a short explanation for rebase in its second example):

3. Crappy documentation

The man pages are one almighty “f*** you”¹. They describe the commands from the perspective of a computer scientist, not a user. Case in point:

git-push – Update remote refs along with associated objects

Here’s a description for humans:

git-push – Upload changes from your local repository into a remote repository

Update, another example: (thanks cgd)

git-rebase – Forward-port local commits to the updated upstream head

Translation:

git-rebase – Sequentially regenerate a series of commits so they can be 
             applied directly to the head node

And then we have

git-merge - Join two or more development histories together

which is a good description.

If you still can't access the management console after a fresh install, check if the management console was enabled. To enable it:

1. Go to the RabbitMQ command prompt.

2. Type:

   rabbitmq-plugins enable rabbitmq_management

I've found the updated answer from this video, the accepted answer didn't work for me.

First clone the latest repo from git (if haven't) using git clone <HTTPs link of the project> (or using SSH) then go to the desire branch using git checkout <branch name> .

Use the command

git log

to check the latest commits. Copy the shal of the particular commit. Then use the command

git fetch origin <Copy paste the shal here>

After pressing enter key. Now use the command

git checkout FETCH_HEAD

Now the particular commit will be available to your local. Change anything and push the code using git push origin <branch name> . That's all. Check the video for reference.

You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015 > 01/02/2016 because 09 > 01. You need to either put your date in a comparable string format or compare DateTime objects which are comparable.

<?php
 $date_now = date("Y-m-d"); // this format is string comparable

if ($date_now > '2016-01-02') {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Or

<?php
 $date_now = new DateTime();
 $date2    = new DateTime("01/02/2016");

if ($date_now > $date2) {
    echo 'greater than';
}else{
    echo 'Less than';
}

We can use RegularExpressionValidator to validate email address format. You need to specify the regular expression in ValidationExpression property of RegularExpressionValidator. So it will look like

 <asp:RegularExpressionValidator ID="validateEmail"    
  runat="server" ErrorMessage="Invalid email."
  ControlToValidate="txtEmail" 
  ValidationExpression="^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$" />

Also in event handler of button or link you need to check !Page.IsValid. Check sample code here : sample code

Also if you don't want to use RegularExpressionValidator you can write simple validate method and in that method usinf RegEx class of System.Text.RegularExpressions namespace.

Check example:

When using Node.js, you can retrieve environment variables by key from the process.env object:

for example

var mode   = process.env.NODE_ENV;
var apiKey = process.env.apiKey; // '42348901293989849243'

Here is the answer that will explain setting environment variables in node.js

Two of them always produce the same answer:

• COUNT(*) counts the number of rows
• COUNT(1) also counts the number of rows

Assuming the pk is a primary key and that no nulls are allowed in the values, then

• COUNT(pk) also counts the number of rows

However, if pk is not constrained to be not null, then it produces a different answer:

• COUNT(possibly_null) counts the number of rows with non-null values in the column possibly_null.

• COUNT(DISTINCT pk) also counts the number of rows (because a primary key does not allow duplicates).

• COUNT(DISTINCT possibly_null_or_dup) counts the number of distinct non-null values in the column possibly_null_or_dup.

• COUNT(DISTINCT possibly_duplicated) counts the number of distinct (necessarily non-null) values in the column possibly_duplicated when that has the NOT NULL clause on it.

Normally, I write COUNT(*); it is the original recommended notation for SQL. Similarly, with the EXISTS clause, I normally write WHERE EXISTS(SELECT * FROM ...) because that was the original recommend notation. There should be no benefit to the alternatives; the optimizer should see through the more obscure notations.

I would add a detail to the most voted answer:

If you're using gvim and want to copy to the clipboard, use

"+<command>

To copy all the content between brackets (or parens or curly brackets)

For example: "+yi} will copy to the clipboard all the content between the curly brackets your cursor is.

I've just encountered the same issue. The problem for me was Windows 7 default unzipper program. It has a problem when it encounters files that have a deep file structure. I read about this issue some time ago but can't recall the article. Fix for me is to unzip the Eclipse download using WinZip (or some other tool which does'nt have this issue).

jQuery.fn.sort = function() {  
    return this.pushStack( [].sort.apply( this, arguments ), []);  
};  

 function sortLastName(a,b){  
     if (a.l_name == b.l_name){
       return 0;
     }
     return a.l_name> b.l_name ? 1 : -1;  
 };  
  function sortLastNameDesc(a,b){  
     return sortLastName(a,b) * -1;  
 };
var people= [
{
"f_name": "john",
"l_name": "doe",
"sequence": "0",
"title" : "president",
"url" : "google.com",
"color" : "333333",
},
{
"f_name": "michael",
"l_name": "goodyear",
"sequence": "0",
"title" : "general manager",
"url" : "google.com",
"color" : "333333",
}]

sorted=$(people).sort(sortLastNameDesc);  

Ok, so this might not fix your issue but it definitely worked for me.

So you've created your Mysql user I take it? Go to user privileges on PhpMyAdmin and click edit next to the user your using for Symfony. Scroll down to near the bottom and where it says which host you want to use make sure you've selected LocalHost not % Any.

Then in your config file swap 127.0.0.1 for localhost. Hopefully that will work for you. Just worked for me as I was having the same issue.

You can add account in the preference -> Accounts setting.

It seems that you already configure xCode4, then I think you can select your certificates for compiling in project-> Building Setting directly since your certificates are already in your keychain.

I will add my experience using saga in production system in addition to the library author's rather thorough answer.

Pro (using saga):

• Testability. It's very easy to test sagas as call() returns a pure object. Testing thunks normally requires you to include a mockStore inside your test.

• redux-saga comes with lots of useful helper functions about tasks. It seems to me that the concept of saga is to create some kind of background worker/thread for your app, which act as a missing piece in react redux architecture(actionCreators and reducers must be pure functions.) Which leads to next point.

• Sagas offer independent place to handle all side effects. It is usually easier to modify and manage than thunk actions in my experience.

Con:

• Generator syntax.

• Lots of concepts to learn.

• API stability. It seems redux-saga is still adding features (eg Channels?) and the community is not as big. There is a concern if the library makes a non backward compatible update some day.

Update for mid 2016:

The things are changing so fast that if it's late 2017 this answer might not be up to date anymore!

Beginners can quickly get lost in choice of build tools and workflows, but what's most up to date in 2016 is not using Bower, Grunt or Gulp at all! With help of Webpack you can do everything directly in NPM!

• Google "npm as build tool" result: https://medium.com/@dabit3/introduction-to-using-npm-as-a-build-tool-b41076f488b0#.c33e74tsa

• Webpack: https://webpack.github.io/docs/installation.html

Don't get me wrong people use other workflows and I still use GULP in my legacy project(but slowly moving out of it), but this is how it's done in the best companies and developers working in this workflow make a LOT of money!

Look at this template it's a very up-to-date setup consisting of a mixture of the best and the latest technologies: https://github.com/coryhouse/react-slingshot

• Webpack
• NPM as a build tool (no Gulp, Grunt or Bower)
• React with Redux
• ESLint
• the list is long. Go and explore!

Your questions:

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

• Everything belongs in package.json now

• Dependencies required for build are in "devDependencies" i.e. npm install require-dir --save-dev (--save-dev updates your package.json by adding an entry to devDependencies)

• Dependencies required for your application during runtime are in "dependencies" i.e. npm install lodash --save (--save updates your package.json by adding an entry to dependencies)

If that is the case, when should I ever install packages explicitly like that without adding them to the file that manages dependencies (apart from installing command line tools globally)?

Always. Just because of comfort. When you add a flag (--save-dev or --save) the file that manages deps (package.json) gets updated automatically. Don't waste time by editing dependencies in it manually. Shortcut for npm install --save-dev package-name is npm i -D package-name and shortcut for npm install --save package-name is npm i -S package-name

In Ubuntu 12.10 (Quantal Quetzal) or later, the certificates are held in the ca-certificates-java package. Using -Djavax.net.ssl.trustStore=/etc/ssl/certs/java/cacerts will pick them up regardless of what JDK you're using.

Your jQuery code works perfectly. The hidden field is being updated.

The first solution is to use the java.util.Random class:

import java.util.Random;

Random rand = new Random();

// Obtain a number between [0 - 49].
int n = rand.nextInt(50);

// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Another solution is using Math.random():

double random = Math.random() * 49 + 1;

or

int random = (int)(Math.random() * 50 + 1);

"Initialized from the environment variable PYTHONPATH, plus an installation-dependent default"

-- http://docs.python.org/library/sys.html#sys.path

JSON.parse() function will do.

or

Using Jquery,

var obj = jQuery.parseJSON( '{ "name": "Vinod" }' );
alert( obj.name === "Vinod" );

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

/* Optional styling */_x000D_
summary::-webkit-details-marker {_x000D_
  color: blue;_x000D_
}_x000D_
summary:focus {_x000D_
  outline-style: none;_x000D_
}

<details>_x000D_
  <summary>Summary, caption, or legend for the content</summary>_x000D_
  Content goes here._x000D_
</details>

See also how to style the <details> element (HTML5 Doctor) (little bit tricky).

Pure CSS3

The :target selector has a pretty good browser support, and it can be used to make a single collapsible element within the frame.

.details,_x000D_
.show,_x000D_
.hide:target {_x000D_
  display: none;_x000D_
}_x000D_
.hide:target + .show,_x000D_
.hide:target ~ .details {_x000D_
  display: block;_x000D_
}

<div>_x000D_
  <a id="hide1" href="#hide1" class="hide">+ Summary goes here</a>_x000D_
  <a id="show1" href="#show1" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>_x000D_
<div>_x000D_
  <a id="hide2" href="#hide2" class="hide">+ Summary goes here</a>_x000D_
  <a id="show2" href="#show2" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>

data=np.genfromtxt(csv_file, delimiter=',', dtype='unicode')

It works fine for me.

There are 2 ways to configure custom error pages for ASP.NET sites:

1. Internet Information Services (IIS) Manager (the GUI)
2. web.config file

This article explains how to do each:

• How To Set Up Custom Error Pages In IIS 7.5 With ASP.NET

The reason your error.aspx page is not displaying might be because you have an error in your web.config. Try this instead:

<configuration>
   <system.web>
      <customErrors defaultRedirect="error.aspx" mode="RemoteOnly">
         <error statusCode="404" redirect="error.aspx"/>
      </customErrors>
   </system.web>
</configuration>

You might need to make sure that Error Pages in IIS Manager - Feature Delegation is set to Read/Write:

Also, this answer may help you configure the web.config file:

• What is the difference between customErrors and httpErrors?

if test -e "$file_name";then
 ...
fi

if grep -q "poet" $file_name; then
  ..
fi

You can do like this

SELECT something
FROM
    (a LEFT JOIN b ON a.a_id = b.b_id) LEFT JOIN c on a.a_aid = c.c_id
WHERE a.parent_id = 'rootID'

If you want to keep the row with the lowest id value:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MIN(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

If you want the id value that is the highest:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MAX(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

The subquery in a subquery is necessary for MySQL, or you'll get a 1093 error.

<?php

instanceof is a keyword that can be used to test if an object is of a specified type.

Example :

public class MainClass {
    public static void main(String[] a) {

    String s = "Hello";
    int i = 0;
    String g;
    if (s instanceof java.lang.String) {
       // This is going to be printed
       System.out.println("s is a String");
    }
    if (i instanceof Integer) {
       // This is going to be printed as autoboxing will happen (int -> Integer)
       System.out.println("i is an Integer");
    }
    if (g instanceof java.lang.String) {
       // This case is not going to happen because g is not initialized and
       // therefore is null and instanceof returns false for null. 
       System.out.println("g is a String");
    } 
} 

Here is my source.

There are a couple more ways with which you can approach this problem. Assuming one of your requirement is to run a shell script/function containing a few shell commands and check if the script ran successfully and throw errors in case of failures.

The shell commands in generally rely on exit-codes returned to let the shell know if it was successful or failed due to some unexpected events.

So what you want to do falls upon these two categories

• exit on error
• exit and clean-up on error

Depending on which one you want to do, there are shell options available to use. For the first case, the shell provides an option with set -e and for the second you could do a trap on EXIT

Should I use exit in my script/function?

Using exit generally enhances readability In certain routines, once you know the answer, you want to exit to the calling routine immediately. If the routine is defined in such a way that it doesn’t require any further cleanup once it detects an error, not exiting immediately means that you have to write more code.

So in cases if you need to do clean-up actions on script to make the termination of the script clean, it is preferred to not to use exit.

Should I use set -e for error on exit?

No!

set -e was an attempt to add "automatic error detection" to the shell. Its goal was to cause the shell to abort any time an error occurred, but it comes with a lot of potential pitfalls for example,

• The commands that are part of an if test are immune. In the example, if you expect it to break on the test check on the non-existing directory, it wouldn't, it goes through to the else condition

  set -e
  f() { test -d nosuchdir && echo no dir; }
  f
  echo survived
  

• Commands in a pipeline other than the last one, are immune. In the example below, because the most recently executed (rightmost) command's exit code is considered ( cat) and it was successful. This could be avoided by setting by the set -o pipefail option but its still a caveat.

  set -e
  somecommand that fails | cat -
  echo survived 
  

Recommended for use - trap on exit

The verdict is if you want to be able to handle an error instead of blindly exiting, instead of using set -e, use a trap on the ERR pseudo signal.

The ERR trap is not to run code when the shell itself exits with a non-zero error code, but when any command run by that shell that is not part of a condition (like in if cmd, or cmd ||) exits with a non-zero exit status.

The general practice is we define an trap handler to provide additional debug information on which line and what cause the exit. Remember the exit code of the last command that caused the ERR signal would still be available at this point.

cleanup() {
    exitcode=$?
    printf 'error condition hit\n' 1>&2
    printf 'exit code returned: %s\n' "$exitcode"
    printf 'the command executing at the time of the error was: %s\n' "$BASH_COMMAND"
    printf 'command present on line: %d' "${BASH_LINENO[0]}"
    # Some more clean up code can be added here before exiting
    exit $exitcode
}

and we just use this handler as below on top of the script that is failing

trap cleanup ERR

Putting this together on a simple script that contained false on line 15, the information you would be getting as

error condition hit
exit code returned: 1
the command executing at the time of the error was: false
command present on line: 15

The trap also provides options irrespective of the error to just run the cleanup on shell completion (e.g. your shell script exits), on signal EXIT. You could also trap on multiple signals at the same time. The list of supported signals to trap on can be found on the trap.1p - Linux manual page

Another thing to notice would be to understand that none of the provided methods work if you are dealing with sub-shells are involved in which case, you might need to add your own error handling.

• On a sub-shell with set -e wouldn't work. The false is restricted to the sub-shell and never gets propagated to the parent shell. To do the error handling here, add your own logic to do (false) || false

  set -e
  (false)
  echo survived
  

• The same happens with trap also. The logic below wouldn't work for the reasons mentioned above.

  trap 'echo error' ERR
  (false)
  

You can also use a small function that will loop through and remove any spaces.

This is very clean and simple.

Public Shared Function RemoveXtraSpaces(strVal As String) As String
     Dim iCount As Integer = 1
     Dim sTempstrVal As String

     sTempstrVal = ""

     For iCount = 1 To Len(strVal)
        sTempstrVal = sTempstrVal + Mid(strVal, iCount, 1).Trim
     Next

     RemoveXtraSpaces = sTempstrVal

     Return RemoveXtraSpaces

End Function

Other than using the Navigator/Proj Explorer and choosing files and doing 'Compare With'->'Each other'... I prefer opening both files in Eclipse and using 'Compare With'->'Opened Editor'->(pick the opened tab)... You can get this feature via the AnyEdit eclipse plugin located here (you can use Install Software via Eclipse->Help->Install New Software screen): http://andrei.gmxhome.de/eclipse/

You should include <string.h> (or its C++ equivalent, <cstring>).

For exe files, I suppose the differences are nearly unimportant.
But to start an exe you don't even need CALL.

When starting another batch it's a big difference,
as CALL will start it in the same window and the called batch has access to the same variable context.
So it can also change variables which affects the caller.

START will create a new cmd.exe for the called batch and without /b it will open a new window.
As it's a new context, variables can't be shared.

Differences

Using start /wait <prog>
- Changes of environment variables are lost when the <prog> ends
- The caller waits until the <prog> is finished

Using call <prog>
- For exe it can be ommited, because it's equal to just starting <prog>
- For an exe-prog the caller batch waits or starts the exe asynchronous, but the behaviour depends on the exe itself.
- For batch files, the caller batch continues, when the called <batch-file> finishes, WITHOUT call the control will not return to the caller batch

Addendum:

Using CALL can change the parameters (for batch and exe files), but only when they contain carets or percent signs.

call myProg param1 param^^2 "param^3" %%path%%

Will be expanded to (from within an batch file)

myProg param1 param2 param^^3 <content of path>

Your question feels a little incomplete, but I think what you're looking for is a way of making your JSON accessible to your code:

if you have the JSON string as above then you'd just need to do this

var jsonObj = eval('[{"id":28,"Title":"Sweden"}, {"id":56,"Title":"USA"}, {"id":89,"Title":"England"}]');

then you can access these vars with something like jsonObj[0].id etc

Let me know if that's not what you were getting at and I'll try to help.

Here's a version that works recursively (using *) on an arbitrary number of objects:

echo '{"A": {"a": 1}}' '{"A": {"b": 2}}' '{"B": 3}' |\
  jq --slurp 'reduce .[] as $item ({}; . * $item)'

{
  "A": {
    "a": 1,
    "b": 2
  },
  "B": 3
}

When in Windows, my preferred GUI tool for this is Cloudberry Explorer for S3., http://www.cloudberrylab.com/free-amazon-s3-explorer-cloudfront-IAM.aspx. Has a fairly polished file explorer, ftp-like interface.

It's called a shebang, and tells the parent shell which interpreter should be used to execute the script.

#!/bin/sh <--------- bourne shell compatible script
#!/usr/bin/perl  <-- perl script
#!/usr/bin/php  <--- php script
#!/bin/false <------ do-nothing script, because false returns immediately anyways.

Most scripting languages tend to interpret a line starting with # as comment and will ignore the following !/usr/bin/whatever portion, which might otherwise cause a syntax error in the interpreted language.

I have started writing one tutorial for everyone on this topic, see making gadgets for Windows 7.

You cannot use references in Java, so a swap function is impossible, but you can use the following code snippet per each use of swap operations:

T t = p
p = q
q = t

where T is the type of p and q

However, swapping mutable objects may be possible by rewriting properties:

void swap(Point a, Point b) {
  int tx = a.x, ty = a.y;
  a.x = b.x; a.y = b.y;
  b.x = t.x; b.y = t.y;
}

public class MyException : Exception
{
    public MyException() { }
    public MyException(string msg) : base(msg) { }
    public MyException(string msg, Exception inner) : base(msg, inner) { }
}

}

If you have more than one view in the layout file android.R.layout.simple_list_item_1 then you'll have to pass the third argument android.R.id.text1 to specify the view that should be filled with the array elements (values). But if you have just one view in your layout file, there is no need to specify the third argument.

A dialog is always created and displayed as a part of an Activity. You need to pass in an Activity context instead of the Application context.

I was facing this issue, too.

The target table is a relation table, wiring two IDs from different tables. I have a UNIQUE constraint on the value combination, replacing the PK. When updating one of the values of a tuple, this error occured.

This is how the table looks like (MySQL):

CREATE TABLE my_relation_table (
  mrt_left_id BIGINT NOT NULL,
  mrt_right_id BIGINT NOT NULL,
  UNIQUE KEY uix_my_relation_table (mrt_left_id, mrt_right_id),
  FOREIGN KEY (mrt_left_id)
    REFERENCES left_table(lef_id),
  FOREIGN KEY (mrt_right_id)
    REFERENCES right_table(rig_id)
);

The Entity class for the RelationWithUnique entity looks basically like this:

@Entity
@IdClass(RelationWithUnique.class)
@Table(name = "my_relation_table")
public class RelationWithUnique implements Serializable {

  ...

  @Id
  @ManyToOne
  @JoinColumn(name = "mrt_left_id", referencedColumnName = "left_table.lef_id")
  private LeftTableEntity leftId;

  @Id
  @ManyToOne
  @JoinColumn(name = "mrt_right_id", referencedColumnName = "right_table.rig_id")
  private RightTableEntity rightId;

  ...

I fixed it by

// usually, we need to detach the object as we are updating the PK
// (rightId being part of the UNIQUE constraint) => PK
// but this would produce a duplicate entry, 
// therefore, we simply delete the old tuple and add the new one
final RelationWithUnique newRelation = new RelationWithUnique();
newRelation.setLeftId(oldRelation.getLeftId());
newRelation.setRightId(rightId);  // here, the value is updated actually
entityManager.remove(oldRelation);
entityManager.persist(newRelation);

Thanks a lot for the hint of the PK, I just missed it.

You can implement your OTF font using @font-face like:

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWeb.otf") format("opentype");
}

@font-face {
    font-family: GraublauWeb;
    font-weight: bold;
    src: url("path/GraublauWebBold.otf") format("opentype");
}

// Edit: OTF now works in most browsers, see comments

However if you want to support a wide variety of browsers i would recommend you to switch to WOFF and TTF font types. WOFF type is implemented by every major desktop browser, while the TTF type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf")  format("truetype");
}

If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:

@font-face {
    font-family: GraublauWeb;
    src: url("webfont.eot"); /* IE9 Compat Modes */
    src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
         url("webfont.woff") format("woff"), /* Modern Browsers */
         url("webfont.ttf")  format("truetype"), /* Safari, Android, iOS */
         url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}

You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:

Literally, just restarted IntelliJ after it kept showing this "install git" message after I have pressed and installed git, and it disappeared, and git works

There is a fourth option in addition to the ones in mfulton26's answer.

By using the ?. operator it is possible to call methods as well as fields without dealing with let or using local variables.

Some code for context:

var factory: ServerSocketFactory = SSLServerSocketFactory.getDefault();
socket = factory.createServerSocket(port)
socket.close()//smartcast impossible
socket?.close()//Smartcast possible. And works when called

It works with methods, fields and all the other things I tried to get it to work.

So in order to solve the issue, instead of having to use manual casts or using local variables, you can use ?. to call the methods.

For reference, this was tested in Kotlin 1.1.4-3, but also tested in 1.1.51 and 1.1.60. There's no guarantee it works on other versions, it could be a new feature.

Using the ?. operator can't be used in your case since it's a passed variable that's the problem. The Elvis operator can be used as an alternative, and it's probably the one that requires the least amount of code. Instead of using continue though, return could also be used.

Using manual casting could also be an option, but this isn't null safe:

queue.add(left as Node);

Meaning if left has changed on a different thread, the program will crash.

This feature is known as generics. http://msdn.microsoft.com/en-us/library/512aeb7t(v=vs.100).aspx

An example of this is to make a collection of items of a specific type.

class MyArray<T>
{
    T[] array = new T[10];

    public T GetItem(int index)
    {
        return array[index];
    }
}

In your code, you could then do something like this:

MyArray<int> = new MyArray<int>();

In this case, T[] array would work like int[] array, and public T GetItem would work like public int GetItem.

Hi I have a simple solution by using 2 themes

1. Splash screen theme (add it to the manifest):

   <style name="SplashTheme" parent="@android:style/Theme.Holo.NoActionBar"> <item name="android:windowBackground">@color/red</item> </style>

2. normal theme (add it in your activity by setTheme(R.style.Theme)):

   <style name="Theme" parent="@style/Theme.Holo"> <item name="android:windowBackground">@color/blue</item> </style>

To support SDK 10:

@Override    
public void onCreate(Bundle savedInstanceState) {

    setTheme(R.style.Theme);      
    super.onCreate(savedInstanceState);

      ...........
      ...........
}

For react version 16.6.3, we use super(props) to initialize state element name : this.props.name

constructor(props){
    super(props);        
}
state = {
  name:this.props.name 
    //otherwise not defined
};

For Python 3:

bytes(apple,'iso-8859-1').decode('utf-8')

I used this for a text incorrectly encoded as iso-8859-1 (showing words like VeÅ\x99ejné) instead of utf-8. This code produces correct version Verejné.

Adding to @jakentus answer, below is what worked for me:

1. Change the file name in the models package to Logon_model.php (First letter upper case as @jakentus correctly said)

2. Change the class name as same as file name i.e.

   class Logon_model extends CI_Model

3. Change the name in the load method too as

   $this->load->model('Logon_model');

Hope this helps. Happy coding. :)

King King's answer is of course right. Also Tim Schmelter's comment is also good suggestion in your case.

But if you want really remove last comma in a string, you should find the index of last comma and remove like;

string s = "1,5,12,34,12345";
int index = s.LastIndexOf(',');
Console.WriteLine(s.Remove(index, 1));

Output will be;

1,5,12,3412345

Here a demonstration.

It is too unlikely you want this way but I want to point it. And remember, String.Remove method doesn't remove any character in original string, it returns new string.

I had the same problem. I tried 'yyyy-mm-dd' format i.e. '2013-26-11' and got rid of this problem...

If your key has a fixed number of digits, you should probably store as text rather than as numeric data. You can use the converters argument or read_excel for this.

Or, if this does not work, just manipulate your data once it's read into your dataframe:

df['key_zfill'] = df['key'].astype(str).str.zfill(4)

  names   key key_zfill
0   abc     5      0005
1   def  4962      4962
2   ghi   300      0300
3   jkl    14      0014
4   mno    20      0020

You could go into the designer of the web form and change the "webcontrols" to be "public" instead of "protected" but I'm not sure how safe that is. I prefer to make hidden inputs and have some jQuery set the values into those hidden inputs, then create public properties in the web form's class (code behind), and access the values that way.

I may be wrong, but from what I understand, this is controlled by the user's browser preferences, and I do not believe that this can be overridden.

I couldn't get the other answers to work within the evaluate console in Intellij so...

groovy.json.JsonOutput.toJson(myObject)

This works quite well, but unfortunately

groovy.json.JsonOutput.prettyString(myObject)

didn't work for me.

To get it pretty printed I had to do this...

groovy.json.JsonOutput.prettyPrint(groovy.json.JsonOutput.toJson(myObject))

Try to test and initialize your arrays before you use them :

if( !isset($catagory[$i]) ) $catagory[$i] = '' ;
if( !isset($task[$i]) ) $task[$i] = '' ;
if( !isset($fullText[$i]) ) $fullText[$i] = '' ;
if( !isset($dueDate[$i]) ) $dueDate[$i] = '' ;
if( !isset($empId[$i]) ) $empId[$i] = '' ;

If $catagory[$i] doesn't exist, you create (Uninitialized) one ... that's all ; => PHP try to read on your table in the address $i, but at this address, there's nothing, this address doesn't exist => PHP return you a notice, and it put nothing to you string. So you code is not very clean, it takes you some resources that down you server's performance (just a very little).

Take care about your MySQL tables default values

if( !isset($dueDate[$i]) ) $dueDate[$i] = '0000-00-00 00:00:00' ;

or

if( !isset($dueDate[$i]) ) $dueDate[$i] = 'NULL' ;

You can do it more simply, guaranteeing that your .gitconfig is left in a meaningful state:

Using Git version v1.8.0 and above

git push -u hub master when pushing, or:
git branch -u hub/master

OR

(This will set the remote for the currently checked-out branch to hub/master)
git branch --set-upstream-to hub/master

OR

(This will set the remote for the branch named branch_name to hub/master)
git branch branch_name --set-upstream-to hub/master

If you're using v1.7.x or earlier

you must use --set-upstream:
git branch --set-upstream master hub/master

hi,that maybe the project's problem,

chose the project and setting you eclipse:

So if want to set the value of an environment variable to something different for every build then we can pass these values during build time and we don't need to change our docker file every time.

While ENV, once set cannot be overwritten through command line values. So, if we want to have our environment variable to have different values for different builds then we could use ARG and set default values in our docker file. And when we want to overwrite these values then we can do so using --build-args at every build without changing our docker file.

For more details, you can refer this.

Thisd was a perfect solution for me, looking it for years:

http://css-tricks.com/forums/topic/two-column-unordered-list/

The params object is included in $stateParams, but won't be part of the url.

1) In the route configuration:

$stateProvider.state('edit_user', {
    url: '/users/:user_id/edit',
    templateUrl: 'views/editUser.html',
    controller: 'editUserCtrl',
    params: {
        paramOne: { objectProperty: "defaultValueOne" },  //default value
        paramTwo: "defaultValueTwo"
    }
});

2) In the controller:

.controller('editUserCtrl', function ($stateParams, $scope) {       
    $scope.paramOne = $stateParams.paramOne;
    $scope.paramTwo = $stateParams.paramTwo;
});

3A) Changing the State from a controller

$state.go("edit_user", {
    user_id: 1,                
    paramOne: { objectProperty: "test_not_default1" },
    paramTwo: "from controller"
});

3B) Changing the State in html

<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>

Example Plunker

Try this to convert String-Bitmap or Bitmap-String

/**
 * @param bitmap
 * @return converting bitmap and return a string
 */
public static String BitMapToString(Bitmap bitmap){
    ByteArrayOutputStream baos=new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG,100, baos);
    byte [] b=baos.toByteArray();
    String temp=Base64.encodeToString(b, Base64.DEFAULT);
    return temp;
}

/**
 * @param encodedString
 * @return bitmap (from given string)
 */
public static Bitmap StringToBitMap(String encodedString){
    try{
        byte [] encodeByte=Base64.decode(encodedString,Base64.DEFAULT);
        Bitmap bitmap= BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
        return bitmap;
    }catch(Exception e){
        e.getMessage();
        return null;
    }
}

When you're exporting to HTML, using <br> works. However, if you're using pandoc to export to LaTeX/PDF as well, you should use grid tables:

+---------------+---------------+--------------------+
| Fruit         | Price         | Advantages         |
+===============+===============+====================+
| Bananas       | first line\   | first line\        |
|               | next line     | next line          |
+---------------+---------------+--------------------+
| Bananas       | first line\   | first line\        |
|               | next line     | next line          |
+---------------+---------------+--------------------+

If you have a big nested JSON object and using it across several screens, you might face performance issues in page loading. I always go for small individual JSON objects and query the related objects as lazy load only where they are required.

you can achieve it using ng-init

<td class="lectureClass" ng-repeat="s in sessions" ng-init='presenters=getPresenters(s.id)'>
      {{s.name}}
      <div class="presenterClass" ng-repeat="p in presenters">
          {{p.name}}
      </div>
</td> 

The code on the controller side should look like below

$scope.getPresenters = function(id) {
    return SessionPresenters.get({id: id});
};

While the API factory is as follows:

angular.module('tryme3App').factory('SessionPresenters', function ($resource, DateUtils) {

        return $resource('api/session.Presenters/:id', {}, {
            'query': { method: 'GET', isArray: true},
            'get': {
                method: 'GET', isArray: true
            },
            'update': { method:'PUT' }
        });
    });

Here is a one liner. A little improvised answer using format with print() to iterate a list.

How about this (python 3.x):

sample_list = ['cat', 'dog', 'bunny', 'pig']
print("Your list of animals are: {}, {}, {} and {}".format(*sample_list))

Read the docs here on using format().

If you're using windows, create this POLL.CMD file

@echo off
:top
xcopy /m /y %1 %2 | find /v "File(s) copied"
timeout /T 1 > nul
goto :top

then you can type "poll dir1 dir2" and it will copy all the files from dir1 to dir2 and check for updates once per second.

The "find" is optional, just to make the console less noisy.

This is not recursive. Maybe you could make it recursive using /e on the xcopy.

Actually I found this more helpful for functions that return IAsyncAction.

            var task = asyncFunction();
            while (task.Status == AsyncStatus.Completed) ;

I know it's an old question, but it's a good one, so how about this?

unsigned short int x = 65529U;
short int y = *(short int*)&x;

printf("%d\n", y);

The range of char is 127 to -128. If you assign 212, ch stores -44 (212-128-128) not 212.So if you try to print a negative number as unsigned you get (MAX value of unsigned int)-abs(number) which in this case is 4294967252

So if you want to store 212 as it is in ch the only thing you can do is declare ch as

unsigned char ch;

now the range of ch is 0 to 255.

Answering this just in case if someone else like me stumbles upon this post among many that advise use of JavaScripts for changing iframe height to 100%.

I strongly recommend that you see and try this option specified at How do you give iframe 100% height before resorting to a JavaScript based option. The referenced solution works perfectly for me in all of the testing I have done so far. Hope this helps someone.

For Error: 'opts' is deprecated. Use theme() instead. (Defunct; last used in version 0.9.1)' I replaced opts(title = "Boxplot - Candidate's Tweet Scores") with labs(title = "Boxplot - Candidate's Tweet Scores"). It worked!

I presume SELECT user FROM dual; should give you the current user

and SELECT sys_context('userenv','instance_name') FROM dual; the name of the instance

I believe you can get SID as SELECT sys_context('USERENV', 'SID') FROM DUAL;

I was getting the same messages while I was running just msbuild from powershell.

dotnet msbuild "./project.csproj" worked for me.

It is not a good idea to return iterators. Iterators become invalid when modifications to the vector (inversion\deletion ) happens. Also, the iterator is a local object created on stack and hence returning the address of the same is not at all safe. I'd suggest you to work with myObject rather than vector iterators.

EDIT: If the object is lightweight then its better you return the object itself. Otheriwise return pointers to myObject stored in the vector.

To remove one or more columns by name, when the column names are known (as opposed to being determined at run-time), I like the subset() syntax. E.g. for the data-frame

df <- data.frame(a=1:3, d=2:4, c=3:5, b=4:6)

to remove just the a column you could do

Data <- subset( Data, select = -a )

and to remove the b and d columns you could do

Data <- subset( Data, select = -c(d, b ) )

You can remove all columns between d and b with:

Data <- subset( Data, select = -c( d : b )

As I said above, this syntax works only when the column names are known. It won't work when say the column names are determined programmatically (i.e. assigned to a variable). I'll reproduce this Warning from the ?subset documentation:

Warning:

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like '[', and in particular the non-standard evaluation of argument 'subset' can have unanticipated consequences.

There might be a margin style that your table is inheriting. Try setting the margin of the table to 0:

<table border="1" width="100%" ID="Table2" style="margin: 0px;">
<tr>
  <td>100</td>
</tr>
</table>

What about :

import platform

h = platform.uname()[1]

Actually you may want to have a look to all the result in platform.uname()

I update my Hibernate JPA to 2.1 and It works.

As of May 2017 this process seems to have changed yet again (a bit).

I did not find it necessary to actually modify anything to do with my profile, and fortunately the certificate was still valid so renewal ended up being a simple process though figuring out exactly what to do was not straightforward.

1. Select the expiring profile in your developer account and click "Edit"
2. Click the "Generate" button
   • Verify that the certificate linked to the profile is still valid for at least a year
   • I did not find it necessary to modify the profile in any way
3. On the next screen, verify that the expiration date of the profile has been extended

This is what I did.

$('.selectpicker').on('changed.bs.select', function (e, clickedIndex, newValue, oldValue) {
    var selected = $(e.currentTarget).val();
});

I use

 android:screenOrientation="nosensor"

It is helpful if you do not want to support up side down portrait mode.

dir(sys) says no. len(sys.argv) works, but in Python it is better to ask for forgiveness than permission, so

#!/usr/bin/python
import sys
try:
    in_file = open(sys.argv[1], "r")
except:
    sys.exit("ERROR. Can't read supplied filename.")
text = in_file.read()
print(text)
in_file.close()

works fine and is shorter.

If you're going to exit anyway, this would be better:

#!/usr/bin/python
import sys
text = open(sys.argv[1], "r").read()
print(text)

I'm using print() so it works in 2.7 as well as Python 3.

In the Notebook

For data exploration in the IPython notebook, my preferred way is this:

sorted(df)

Which will produce an easy to read alphabetically ordered list.

In a code repository

In code I find it more explicit to do

df.columns

Because it tells others reading your code what you are doing.

It is possible to run the war as a Linux service, and you may want to force in your pom.xml file before packaging, as some distros may not recognize in auto mode. To do it, add the following property inside of spring-boot-maven-plugin plugin.

                    <embeddedLaunchScriptProperties>
                        <mode>service</mode>
                    </embeddedLaunchScriptProperties>

Next, setup your init.d with:

ln -s myapp.war /etc/init.d/myapp

and you will be able to run

service myapp start|stop|restart

There are many other options that you can find in Spring Boot documentation, including Windows service.

The accepted answer of how to create an Index inline a Table creation script did not work for me. This did:

CREATE TABLE [dbo].[TableToBeCreated]
(
    [Id] BIGINT IDENTITY(1, 1) NOT NULL PRIMARY KEY
    ,[ForeignKeyId] BIGINT NOT NULL
    ,CONSTRAINT [FK_TableToBeCreated_ForeignKeyId_OtherTable_Id] FOREIGN KEY ([ForeignKeyId]) REFERENCES [dbo].[OtherTable]([Id])
    ,INDEX [IX_TableToBeCreated_ForeignKeyId] NONCLUSTERED ([ForeignKeyId])
)

Remember, Foreign Keys do not create Indexes, so it is good practice to index them as you will more than likely be joining on them.

I know the difference between a declaration and a definition.

Whereas:

• A CPP file includes the definitions from any header which it includes (because CPP and header file together become a single 'translation unit')
• A header file might be included by more than one CPP file
• The linker typically won't like anything defined in more than one CPP file

Therefore any definitions in a header file should be inline or static. Header files also contain declarations which are used by more than one CPP file.

Definitions that are neither static nor inline are placed in CPP files. Also, any declarations that are only needed within one CPP file are often placed within that CPP file itself, nstead of in any (sharable) header file.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

The Best Command for changing branch

git branch -M YOUR_BRANCH

You could do something like this:

var a = (function() {
    var original_a = a;

    if (condition) {
        return function() {
            new_code();
            original_a();
        }
    } else {
        return function() {
            original_a();
            other_new_code();
        }
    }
})();

Declaring original_a inside an anonymous function keeps it from cluttering the global namespace, but it's available in the inner functions.

Like Nerdmaster mentioned in the comments, be sure to include the () at the end. You want to call the outer function and store the result (one of the two inner functions) in a, not store the outer function itself in a.

When I publish apps I use the following screenshot sizes:

Phone: 1080 x 1920 I prepare 8 images with title, some fancy background and a screenshot inside a smartphone mockup. So it's more than a simple screenshot. It gives some nice branding and helps you to stand out from other apps out there.

Tablet 7": 1200 x 1920 - I do actually a couple of raw screenshots of 7" emulator so that the user could know how the layout will appear on his device. No fancy design with titles etc.

Tablet 10": 1800 x 2560 - same thing here, just a couple of raw screenshots.

all in .png format. Hope this helps.

There's two types of superfluous #include files:

1. A header file actually not needed by the module(.c, .cpp) at all
2. A header file is need by the module but being included more than once, directly, or indirectly.

There's 2 ways in my experience that works well to detecting it:

• gcc -H or cl.exe /showincludes (resolve problem 2)

  In real world, you can export CFLAGS=-H before make, if all the Makefile's not override CFLAGS options. Or as I used, you can create a cc/g++ wrapper to add -H options forcibly to each invoke of $(CC) and $(CXX). and prepend the wrapper's directory to $PATH variable, then your make will all uses you wrapper command instead. Of course your wrapper should invoke the real gcc compiler. This tricks need to change if your Makefile uses gcc directly. instead of $(CC) or $(CXX) or by implied rules.

  You can also compile a single file by tweaking with the command line. But if you want to clean headers for the whole project. You can capture all the output by:

  make clean

  make 2>&1 | tee result.txt

• PC-Lint/FlexeLint(resolve problem both 1 and 2)

  make sure add the +e766 options, this warning is about: unused header files.

  pclint/flint -vf ...

  This will cause pclint output included header files, nested header files will be indented appropriately.

You can use sejda-console, free and open source. Unzip it and run sejda-console merge -f file1.pdf file2.pdf -o merged.pdf

It preserves bookmarks, link annotations, acroforms etc.. it actually has quite a lot of options you can play with, just run sejda-console merge -h to see them all.

/^\d+(?:, ?\d+)*$/

onkeypress = > preventdefault ...

You can use REINDEX to do that.

Reindex does not attempt to set up the destination index. It does not copy the settings of the source index. You should set up the destination index prior to running a _reindex action, including setting up mappings, shard counts, replicas, etc.

1. First copy the index to a new name

POST /_reindex

Although this is an old post, I think what one really needs to understand, is not the "move this to that" approach but that the answer involves using the side-effect of the recursion.

A invaluable help to me was the "The Little Schemer" which teaches one to think and write recursive functions.

However, this teaches the reader to use the results of the returned result in the next recursive call.

In the Tower of Hanoi, the answer is not in the returned result per se, but in the observation of the returned result.

The magic occurs in the succesive rearrangment of the function parameters.

Yes the problem is really in three parts:

• moving a smaller tower to the spare peg
• moving the last disc to the destination peg
• moving the remaining tower on the spare peg to the destination peg.

In Scheme:

(define (th n a b c)
    (if (zero? n) 'done
        (begin
           (th (- n 1) a c b)
           (display (list a c))
           (newline)
           (th (- n 1) b a c))))
(th 5 'source 'spare 'destination)

However it is the displaying of the function parameters which is the solution to the problem and crucially understanding the double tree like structure of the calls.

The solution also conveys the power of proof by induction and a warm glow to all programmers who have wrestled with conventional control structures.

Incidently, to solve the problem by hand is quite satisfying.

• count the number of discs
• if even, move the first disc to the spare peg, make next legal move (not involving the top disc). Then move the top disc to the destination peg, make the next legal move(nittd). Then move the top disc to the source peg, make the next legal move(nittd)...
• if odd, move the first disc to the destination peg, make the next legal move (not involving the top disc). Then move the top disc to the spare peg, make the next legal move(nittd). Then move the top disc to the source peg, make the next legal move(nittd)...

Best done by always holding the top disc with the same hand and always moving that hand in the same direction.

The final number of moves for n discs is 2^n - 1 the move n disc to destination is halfway through the process.

Lastly, it is funny how explaining a problem to a colleague, your wife/husband or even the dog (even it they not listening) can cement enlightenment.

You should add the g modifier so that sed performs a global substitution of the contents of the pattern buffer:

echo dog dog dos | sed -e 's:dog:log:g'

For a fantastic documentation on sed, check http://www.grymoire.com/Unix/Sed.html. This global flag is explained here: http://www.grymoire.com/Unix/Sed.html#uh-6

The official documentation for GNU sed is available at http://www.gnu.org/software/sed/manual/

You can also check out SQL Azure Data Sync in the Windows Azure Management Portal. It allows you to retrieve and restore an entire database, including schema and data between SQL Azure and SQL Server.

You are trying to pass pointers (which you do not delete, thus leaking memory) where references are needed. You do not really need pointers here:

Complex firstComplexNumber(81, 93);
Complex secondComplexNumber(31, 19);

cout << "Numarul complex este: " << firstComplexNumber << endl;
//                                  ^^^^^^^^^^^^^^^^^^ No need to dereference now

// ...

Complex::distanta(firstComplexNumber, secondComplexNumber);

What will you do when a user hits ALT + F4 or closes it from Task Manager

Why don't you keep track if they did not complete it in a cookie or the DB and when they visit next time just bring the same screen back...:BTW..you haven't finished filling this form out..."

Of course if you were around before the dotcom bust you would remember porn storms, where if you closed 1 window 15 others would open..so yes there is code that will detect a window closing but if you hit ALT + F4 twice it will close the child and the parent (if it was a popup)

I am doing something very similar. I'm just getting into coding, so this may not be the most efficient way of doing it, but this is how I did it:

@ECHO OFF
ECHO HELLO
ping localhost -n 1 >nul
cls
color 01
ECHO HELLO
ping localhost -n 1 >nul
cls
color 02
ECHO HELLO 

and so one and so forth.

If you want to circumvent this problem you could also use the shelve. Then you would create files that would be the size of your machines capacity to handle, and only put them on the RAM when necessary, basically writing to the HD and pulling the information back in pieces so you can process it.

Create binary file and check if information is already in it if yes make a local variable to hold it else write some data you deem necessary.

Data = shelve.open('File01')
   for i in range(0,100):
     Matrix_Shelve = 'Matrix' + str(i)
     if Matrix_Shelve in Data:
        Matrix_local = Data[Matrix_Shelve]
     else:
        Data[Matrix_Selve] = 'somenthingforlater'

Hope it doesn't sound too arcaic.

if you write Component as React.FC, and using useState(),

just write like this would be helpful:

const [arr, setArr] = useState<any[]>([])

why do I have to pass seconds = uptime to timedelta

Because timedelta objects can be passed seconds, milliseconds, days, etc... so you need to specify what are you passing in (this is why you use the explicit key). Typecasting to int is superfluous as they could also accept floats.

and why does the string casting works so nicely that I get HH:MM:SS ?

It's not the typecasting that formats, is the internal __str__ method of the object. In fact you will achieve the same result if you write:

print datetime.timedelta(seconds=int(uptime))

$('tbody').find('tr:visible').hightlight(myArray[i]);

Add the sheet name infront of the cell, e.g.:

=COUNTIFS(stock!A:A,"M",stock!C:C,"Yes")

Assumes the sheet name is "stock"

Try this code

SELECT REPLACE([Column], char(9), '') From [dbo.Table] 

char(9) is the TAB character

//How to solve BigDecimal & BigInteger and return a String.

I had the same problem that occurred after I restored data from a postgres dumped db.

My dump file had the command below from where things started going south.

    SELECT pg_catalog.set_config('search_path', '', false);

Solutions:

1. Probably remove it or change that false to be true.
2. Create a private schema that will be used to access all the tables.

The command above simply deactivates all the publicly accessible schemas.

Check more on the documentation here: https://www.postgresql.org/docs/9.3/ecpg-connect.html

Sometimes you can reference a Windows "shortcut" file to launch an application instead of using a ".bat" file, and it won't have the residual prompt problem. But it's not as flexible as bat files.

Looks like a server issue (i.e. a "GitHub" issue).
If you look at this thread, it can happen when the git-http-backend gets a corrupted heap.(and since they just put in place a smart http support...)
But whatever the actual cause is, it may also be related with recent sporadic disruption in one of the GitHub fileserver.

Do you still see this error message? Because if you do:

• check your local Git version (and upgrade to the latest one)
• report this as a GitHub bug.

Note: the Smart HTTP Support is a big deal for those of us behind an authenticated-based enterprise firewall proxy!

From now on, if you clone a repository over the http:// url and you are using a Git client version 1.6.6 or greater, Git will automatically use the newer, better transport mechanism.
Even more amazing, however, is that you can now push over that protocol and clone private repositories as well. If you access a private repository, or you are a collaborator and want push access, you can put your username in the URL and Git will prompt you for the password when you try to access it.

Older clients will also fall back to the older, less efficient way, so nothing should break - just newer clients should work better.

So again, make sure to upgrade your Git client first.

globbing **

Using grep -r works, but it may overkill, especially in large folders.

For more practical usage, here is the syntax which uses globbing syntax (**):

grep "texthere" **/*.txt

which greps only specific files with pattern selected pattern. It works for supported shells such as Bash +4 or zsh.

To activate this feature, run: shopt -s globstar.

See also: How do I find all files containing specific text on Linux?

git grep

For projects under Git version control, use:

git grep "pattern"

which is much quicker.

ripgrep

For larger projects, the quickest grepping tool is ripgrep which greps files recursively by default:

rg "pattern" .

It's built on top of Rust's regex engine which uses finite automata, SIMD and aggressive literal optimizations to make searching very fast. Check the detailed analysis here.

In my case namespaces parameter was not matching the namespace of the controller.

public override void RegisterArea(AreaRegistrationContext context) 
{
    context.MapRoute(
        "Admin_default",
        "Admin/{controller}/{action}/{id}",
        new {controller = "Home", action = "Index", id = UrlParameter.Optional },
        namespaces: new[] { "Web.Areas.Admin.Controllers" }
    );
}

If you want to change your number into a list of those numbers, I would first cast it to a string, then casting it to a list will naturally break on each character:

[int(x) for x in str(n)]

I was just wondering how most people fetch a mime type from a file in Java?

I've published my SimpleMagic Java package which allows content-type (mime-type) determination from files and byte arrays. It is designed to read and run the Unix file(1) command magic files that are a part of most ~Unix OS configurations.

I tried Apache Tika but it is huge with tons of dependencies, URLConnection doesn't use the bytes of the files, and MimetypesFileTypeMap also just looks at files names.

With SimpleMagic you can do something like:

// create a magic utility using the internal magic file
ContentInfoUtil util = new ContentInfoUtil();
// if you want to use a different config file(s), you can load them by hand:
// ContentInfoUtil util = new ContentInfoUtil("/etc/magic");
...
ContentInfo info = util.findMatch("/tmp/upload.tmp");
// or
ContentInfo info = util.findMatch(inputStream);
// or
ContentInfo info = util.findMatch(contentByteArray);

// null if no match
if (info != null) {
   String mimeType = info.getMimeType();
}

I solved the same problem. I've just added JSTL-1.2.jar to /apache-tomcat-x.x.x/lib and set scope to provided in maven pom.xml:

 <dependency>
     <groupId>jstl</groupId>
     <artifactId>jstl</artifactId>
     <version>1.2</version>
     <scope>provided</scope>
 </dependency>

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

I found a solution for my problem, There was a conflict in my network adapters, I simply disabled the one who appears in the error message, then started again the running command, and a new adapter has been created after many approval messages from windows.

I hope this solution could help in some cases.

document.getElementById('yourId')

is the correct way.

the document refers the HTML document that is loaded in the DOM.

and it searches the id using the function getElementById() which takes a parameter of the id of an element

Solution will be :

var elem = (document.getElementById('myElement'))? document.getElementById('myElement').value : '';

/* this will assign a value or give you and empty string */

Check that there are no missing references - to do this, go to the database window and click on "Modules", then "Design", then select the menu "Tools" and then "References". Or try doing a compile and see if it compiles fully (go to the Debug menu then select Compile) - it might tell you of a missing reference e.g. Microsoft Office 11.0 Object Library. Select References from the Tools menu again and see if any references are ticked and say "MISSING:". In some cases you can select a different version from the list, if 11.0 is missing, look for version 12.0 then recompile. That usually does the trick for me.

Here in simpler words:

DOM

• Tree model parser (Object based) (Tree of nodes).

• DOM loads the file into the memory and then parse- the file.

• Has memory constraints since it loads the whole XML file before parsing.

• DOM is read and write (can insert or delete nodes).

• If the XML content is small, then prefer DOM parser.

• Backward and forward search is possible for searching the tags and evaluation of the information inside the tags. So this gives the ease of navigation.

• Slower at run time.

SAX

• Event based parser (Sequence of events).

• SAX parses the file as it reads it, i.e. parses node by node.

• No memory constraints as it does not store the XML content in the memory.

• SAX is read only i.e. can’t insert or delete the node.

• Use SAX parser when memory content is large.

• SAX reads the XML file from top to bottom and backward navigation is not possible.

• Faster at run time.

sample code show custom dialog in kotlin:

fun showDlgFurtherDetails(context: Context,title: String?, details: String?) {

    val dialog = Dialog(context)
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
    dialog.setCancelable(false)
    dialog.setContentView(R.layout.dlg_further_details)
    dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
    val lblService = dialog.findViewById(R.id.lblService) as TextView
    val lblDetails = dialog.findViewById(R.id.lblDetails) as TextView
    val imgCloseDlg = dialog.findViewById(R.id.imgCloseDlg) as ImageView

    lblService.text = title
    lblDetails.text = details
    lblDetails.movementMethod = ScrollingMovementMethod()
    lblDetails.isScrollbarFadingEnabled = false
    imgCloseDlg.setOnClickListener {
        dialog.dismiss()
    }
    dialog.show()
}

Solution: Give up!

Hear me out, I spent about two whole days trying to make MySQL work to no avail, always stuck with permission errors, none of which were fixed by the answers in this thread. It got to the point that I thought if I continued I'd go insane.

Out of patience for making it work, I sent the command to install SQLite, only using 450KB, and it worked perfectly right from the word go.

If you don't have the patience of a saint, go with SQLite and save yourself a lot of time, effort, pain, and storage space..!

You are deleting the row from the gridview but you are then going and calling databind again which is just refreshing the gridview to the same state that the original datasource is in.

Either remove it from the datasource and then databind, or databind and remove it from the gridview without redatabinding.

OUTDATED See Lukas Eder's answer below.

With about 100 lines of code ;-) Here is an example.

I suggest that you move this code into a helper method/class. Otherwise, it will pollute the rest of your code.

This works as of cloc 1.68:

As said in previous responses, their is no OOP-like inheritance in CSS. But if you want to reuse a rule-set to apply it to descentants of something, changing properties, and if you can use LESS, try Mixins. To resume on OOP features, it looks like composition.

For instance, you want to apply the .paragraph class which is in a file "text.less" to all p children of paragraphsContainer, and redefine the color property from red to black

text.less file

.paragraph {
    font: arial;
    color: red
}

Do this in an alternativeText.less file

@import (reference) 'text.less';    
div#paragraphsContainer > p {
    .paragraph;
    color: black
}

your.html file

<div id='paragraphsContainer'>
   <p>paragraph 1</p>
   <p>paragraph 2</p>
   <p>paragraph 3</p>
</div>

Please read this answer about defining same css property multiple times

I posted a fix for this here

You can use this function to modify JSON.stringify to encode arrays, just post it near the beginning of your script (check the link above for more detail):

// Upgrade for JSON.stringify, updated to allow arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

Edit!: Please be sure that you should have both Python installed on your computer.

Maybe my answer is late for you but I can help someone who has the same problem!

You don't have to download both Anaconda.

If you are using Spyder and Jupyter in Anaconda environmen and,

If you have already Anaconda 2 type in Terminal:

    python3 -m pip install ipykernel

    python3 -m ipykernel install --user

If you have already Anaconda 3 then type in terminal:

    python2 -m pip install ipykernel

    python2 -m ipykernel install --user

Then before use Spyder you can choose Python environment like below! Sometimes only you can see root and your new Python environment, so root is your first anaconda environment!

Also this is Jupyter. You can choose python version like this!

I hope it will help.

Making local variables and method parameters final is essential if you want to pass those parameters into anonymous classes - like you instantiate an anonymous Thread and want to access those params in the body of the run() method.

Apart from that I am not sure of the performance benefits w.r.t better performance through compiler optimization. It is up to the specific compiler implementation whether it wants to optimize it at all...

It will be good to know of any performance stats from using final ...

It is returning a Buffer object.

If you want it in a string, you can convert it with data.toString():

var fs = require("fs");

fs.readFile("test.txt", function (err, data) {
    if (err) throw err;
    console.log(data.toString());
});

The loop in your code is only an over-simplified example, right?

It would be better to create the PreparedStatement only once, and re-use it over and over again in the loop.

In situations where that is not possible (because it complicated the program flow too much), it is still beneficial to use a PreparedStatement, even if you use it only once, because the server-side of the work (parsing the SQL and caching the execution plan), will still be reduced.

To address the situation that you want to re-use the Java-side PreparedStatement, some JDBC drivers (such as Oracle) have a caching feature: If you create a PreparedStatement for the same SQL on the same connection, it will give you the same (cached) instance.

About multi-threading: I do not think JDBC connections can be shared across multiple threads (i.e. used concurrently by multiple threads) anyway. Every thread should get his own connection from the pool, use it, and return it to the pool again.

Here there are two issues we have to concentrate on:

1. HAX device failed to open,

   For this problem, you have to run the HAX device setup file from the HAX addon folder. Follow Speed Up Android Emulator to know clearly how.

2. If you created the AVD through AVD manager then you can change the RAM size in AVD Manager and device edit option.

If you created the AVD through command line, then you should start the AVD from command line will work,

emulator -memory 512 -avd gtv_avd

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

Try this:

var jIsHasKids = $('#chkIsHasKids').attr('checked');
jIsHasKids = jIsHasKids.toString().toLowerCase();
//OR
jIsHasKids = jIsHasKids.val().toLowerCase();

It's now possible, I just released an enhanced version of the TypeScript compiler that provides full reflection capabilities. You can instantiate classes from their metadata objects, retrieve metadata from class constructors and inspect interface/classes at runtime. You can check it out here

Usage example:

In one of your typescript files, create an interface and a class that implements it like the following:

interface MyInterface {
    doSomething(what: string): number;
}

class MyClass implements MyInterface {
    counter = 0;

    doSomething(what: string): number {
        console.log('Doing ' + what);
        return this.counter++;
    }
}

now let's print some the list of implemented interfaces.

for (let classInterface of MyClass.getClass().implements) {
    console.log('Implemented interface: ' + classInterface.name)
}

compile with reflec-ts and launch it:

$ node main.js
Implemented interface: MyInterface
Member name: counter - member kind: number
Member name: doSomething - member kind: function

See reflection.d.ts for Interface meta-type details.

If you are trying to install matplotlib in order to work with graphs on python. Try this link. https://github.com/jbmohler/matplotlib-winbuild. This is a set of scripts to build matplotlib from source on the MS Windows platform.

To build & install matplotlib in your Python, do:

git clone https://github.com/matplotlib/matplotlib
git clone https://github.com/jbmohler/matplotlib-winbuild
$ python matplotlib-winbuild\buildall.py

The build script will auto-detect Python version & 32/64 bit automatically.

Solution

You want to (1) create stdout output in one process (like echo '…') and (2) redirect that output to stdin input of another process but (3) without the use of the bash pipe mechanism. Here's a solution that matches all three conditions:

/my/bash/script < <(echo 'This string will be sent to stdin.')

The < is normal input redirection for stdin. The <(…) is bash process substitution. Roughly it creates a /dev/fd/… file with the output of the substituting command and passes that filename in place of the <(…), resulting here for example in script < /dev/fd/123. For details, see this answer.

Comparison with other solutions

• A one-line heredoc sent to stdin script <<< 'string' only allows to send static strings, not the output of other commands.

• Process substitution alone, such as in diff <(ls /bin) <(ls /usr/bin), does not send anything to stdin. Instead, the process output is saved into a file, and its path is passed as a command line argument. For the above example, this is equivalent to diff /dev/fd/10 /dev/fd/11, a command where diff receives no input from stdin.

Use cases

I like that, unlike the pipe mechanism, the < <(…) mechanism allows to put the command first and all input after it, as is the standard for input from command line options.

However, beyond commandline aesthetics, there are some cases where a pipe mechanism cannot be used. For example, when a certain command has to be provided as argument to another command, such as in this example with sshpass.

For anyone who came here looking for how to get the true accordion effect and only allow one row to be expanded at a time, you can add an event handler for show.bs.collapse like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified this example to do so here: http://jsfiddle.net/QLfMU/116/

Try the following code:

const moment=require('moment');
console.log("startDate=>",moment().startOf('month').format("YYYY-DD-MM"));
console.log("endDate=>",moment().endOf('month').format("YYYY-DD-MM"));

A different way:

public boolean contains(final int[] array, final int key) {  
     Arrays.sort(array);  
     return Arrays.binarySearch(array, key) >= 0;  
}  

This modifies the passed-in array. You would have the option to copy the array and work on the original array i.e. int[] sorted = array.clone();
But this is just an example of short code. The runtime is O(NlogN) while your way is O(N)

Use Bash and the date command to convert from an ISO-like format to the one you want. I wanted an org-mode date format (and list item), so I did this:

echo + [$(date -d "$(git log --pretty=format:%ai -1)" +"%Y-%m-%d %a %H:%M")] \
    $(git log --pretty=format:"%h %s" --abbrev=12 -1)

And the result is for example:

You cannot use IF control block OUTSIDE of functions. So that affects both of your queries.

Turn the EXISTS clause into a subquery instead within an IF function

SELECT IF( EXISTS(
             SELECT *
             FROM gdata_calendars
             WHERE `group` =  ? AND id = ?), 1, 0)

In fact, booleans are returned as 1 or 0

SELECT EXISTS(
         SELECT *
         FROM gdata_calendars
         WHERE `group` =  ? AND id = ?)

Just make a selector for tables inside a MyClass.

.MyClass td {border: solid 1px red;}
.MyClass table td {border: none}

(To generically apply to all inner tables, you could also do table table td.)

Try

num.toString(2);

The 2 is the radix and can be any base between 2 and 36

UPDATE:

This will only work for positive numbers, Javascript represents negative binary integers in two's-complement notation. I made this little function which should do the trick, I haven't tested it out properly:

function dec2Bin(dec)
{
    if(dec >= 0) {
        return dec.toString(2);
    }
    else {
        /* Here you could represent the number in 2s compliment but this is not what 
           JS uses as its not sure how many bits are in your number range. There are 
           some suggestions https://stackoverflow.com/questions/10936600/javascript-decimal-to-binary-64-bit 
        */
        return (~dec).toString(2);
    }
}

I had some help from here

Simple answer with sample answer ;-)

on iOS Simulator,

Press Command + control + c or from menu : Edit>Copy Screen

open "Preview" app, Press Command + n or from menu : File> New from clipboard , then you can save Command + s

UnCheck Alpha

You can change Image dimension to your requirement.

Here is the Final Image,For example

Here the async version.

public static Task<BitmapSource> ToBitmapSourceAsync(this Bitmap bitmap)
{
    return Task.Run(() =>
    {
        using (System.IO.MemoryStream memory = new System.IO.MemoryStream())
        {
            bitmap.Save(memory, ImageFormat.Png);
            memory.Position = 0;
            BitmapImage bitmapImage = new BitmapImage();
            bitmapImage.BeginInit();
            bitmapImage.StreamSource = memory;
            bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
            bitmapImage.EndInit();
            bitmapImage.Freeze();
            return bitmapImage as BitmapSource;
        }
    });

}

For the image that is not showing up. Open the image in the Image editor and check the type you are probably name it as "gif" but its saved in a different format that's one reason that the browser is unable to render it and it is not showing.
For the image stretching issue please specify the actual width and height dimensions in #banner instead of width: 100%; height: 200px that you have specified.

Residuum did provide a correct answer to how you should get shell exec to find your script, but in regards to security, there are a couple of points.

I would imagine you don't want your shell script to be in your web root, as it would be visible to anyone with web access to your server.

I would recommend moving the shell script to outside of the webroot

    <?php
      $tempFolder = '/tmp';
      $webRootFolder = '/var/www';
      $scriptName = 'myscript.sh';
      $moveCommand = "mv $webRootFolder/$scriptName $tempFolder/$scriptName";
      $output = shell_exec($moveCommand);
    ?>

In regards to the:

i added www-data ALL=(ALL) NOPASSWD:ALL to /etc/sudoers works

You can modify this to only cover the specific commands in your script which require sudo. Otherwise, if none of the commands in your sh script require sudo to execute, you don't need to do this at all anyway.

Try running the script as the apache user (use the su command to switch to the apache user) and if you are not prompted for sudo or given permission denied, etc, it'll be fine.

ie:

sudo su apache (or www-data)
cd /var/www
sh ./myscript

Also... what brought me here was that I wanted to run a multi line shell script using commands that are dynamically generated. I wanted all of my commands to run in the same shell, which won't happen using multiple calls to shell_exec(). The answer to that one is to do it like Jenkins - create your dynamically generated multi line of commands, put it in a variable, save it to a file in a temp folder, execute that file (using shell_exec in() php as Jenkins is Java), then do whatever you want with the output, and delete the temp file

... voila

I would suggest you to use CryptoJS in this case.

Basically CryptoJS is a growing collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns. They are fast, and they have a consistent and simple interface.

So In case you want calculate hash(MD5) of your password string then do as follows :

<script src="http://crypto-js.googlecode.com/svn/tags/3.0.2/build/rollups/md5.js"></script>
<script>
    var passhash = CryptoJS.MD5(password).toString();

    $.post(
      'includes/login.php', 
      { user: username, pass: passhash },
      onLogin, 
      'json' );
</script>

So this script will post hash of your password string to the server.

For further info and support on other hash calculating algorithms you can visit at:

Figuring out package dependencies is really not that hard. You rarely do it anyway. Probably once during project setup and few more during upgrades. With maven you'll end up fixing mismatched dependencies, badly written poms, and doing package exclusions anyway.

Not that hard... for toy projects. But the projects I work on have many, really many, of them, and I'm very glad to get them transitively, to have a standardized naming scheme for them. Managing all this manually by hand would be a nightmare.

And yes, sometimes you have to work on the convergence of dependencies. But think about it twice, this is not inherent to Maven, this is inherent to any system using dependencies (and I am talking about Java dependencies in general here).

So with Ant, you have to do the same work except that you have to do everything manually: grabbing some version of project A and its dependencies, grabbing some version of project B and its dependencies, figuring out yourself what exact versions they use, checking that they don't overlap, checking that they are not incompatible, etc. Welcome to hell.

On the other hand, Maven supports dependency management and will retrieve them transitively for me and gives me the tooling I need to manage the complexity inherent to dependency management: I can analyze a dependency tree, control the versions used in transitive dependencies, exclude some of them if required, control the converge across modules, etc. There is no magic. But at least you have support.

And don't forget that dependency management is only a small part of what Maven offers, there is much more (not even mentioning the other tools that integrates nicely with Maven, e.g. Sonar).

Slow FIX-COMPILE-DEPLOY-DEBUG cycle, which kills productivity. This is my main gripe. You make a change, the you have to wait for maven build to kick in and wait for it to deploy. No hot deployment whatsoever.

First, why do you use Maven like this? I don't. I use my IDE to write tests, code until they pass, refactor, deploy, hot deploy and run a local Maven build when I'm done, before to commit, to make sure I will not break the continuous build.

Second, I'm not sure using Ant would make things much better. And to my experience, modular Maven builds using binary dependencies gives me faster build time than typical monolithic Ant builds. Anyway, have a look at Maven Shell for a ready to (re)use Maven environment (which is awesome by the way).

So at end, and I'm sorry to say so, it's not really Maven that is killing your productivity, it's you misusing your tools. And if you're not happy with it, well, what can I say, don't use it. Personally, I'm using Maven since 2003 and I never looked back.

You can do your whole program in one line! Yes, that is right, one line!

Console.WriteLine(DateTime.Now.ToString("yyyy.MM.dd"));

You may notice that I did not use the same date format as you. That is because you should use the International Date Format as described in this W3C document. Every time you don't use it, somewhere a cute little animal dies.

Try

$("#myModal").modal("toggle")

To open or close the modal with id myModal.

If the above is not working then it means bootstrap.js has been overridden by some other js file. Here is a solution

1:- Move bootstrap.js to the bottom so that it will override other js files.

2:- Make sure the order is like below

<script src="plugins/jQuery/jquery-2.2.3.min.js"></script>
<!-- Other js files -->
<script src="plugins/jQuery/bootstrap.min.js"></script>

Short answer: no.

This is probably a duplicate, can't find an appropriate one right now.

Java uses something called type erasure, which means at runtime both objects are equivalent. The compiler knows the lists contain integers or strings, and as such can maintain a type safe environment. This information is lost (on an object instance basis) at runtime, and the list only contain 'Objects'.

You CAN find out a little about the class, what types it might be parametrized by, but normally this is just anything that extends "Object", i.e. anything. If you define a type as

class <A extends MyClass> AClass {....}

AClass.class will only contain the fact that the parameter A is bounded by MyClass, but more than that, there's no way to tell.

Here are some other files that may be left behind by setuptools:

MANIFEST
*.egg-info

For large datasets, how about JQuery UI Autocomplete, which is basically the "official" version of Jorn Zaeferrer's Autocomplete plugin?

I also wrote a straight JQuery combobox plugin that's gotten pretty good feedback from its users. It's explicitly not meant for large datasets though; I figure that if you want something that prunes the list based on what the user types, you're better off with Jorn's autocompletion plugin.

For Java 8 ....

There is a good solution at https://stackoverflow.com/a/36315051/2648077 post.

This uses Java 8 Supplier functional interface

You need

.abc,.ab {
    display: none;
}

#f:hover ~ .ab {
    display: block;
}

#s:hover ~ .abc {
    display: block;
}

#s:hover ~ .a,
#f:hover ~ .a{
    display: none;
}

Updated demo at http://jsfiddle.net/gaby/n5fzB/2/

The problem in your original CSS was that the , in css selectors starts a completely new selector. it is not combined.. so #f:hover ~ .abc,.a means #f:hover ~ .abc and .a. You set that to display:none so it was always set to be hidden for all .a elements.

Another option could be:

var initial = function() {
    console.log( 'initial function!' );
}

var iWantToExecuteThisOneToo = function () {
    console.log( 'the other function that i wanted to execute!' );
}

function extendFunction( oldOne, newOne ) {
    return (function() {
        oldOne();
        newOne();
    })();
}

var extendedFunction = extendFunction( initial, iWantToExecuteThisOneToo );

This works at the moment (Oct. 2016), but I can't guarantee how long it will last:

cat a.sh
#! /bin/bash

#going forward report subshell or command exit value if errors
#set -e
(cat b.txt)
echo "hi"

./a.sh; echo $?
cat: b.txt: No such file or directory
hi
0

with set -e commented out we see that echo "hi" exit status being reported and hi is printed.

cat a.sh
#! /bin/bash

#going forward report subshell or command exit value if errors
set -e
(cat b.txt)
echo "hi"

./a.sh; echo $?
cat: b.txt: No such file or directory
1

Now we see b.txt error being reported instead and no hi printed.

So default behaviour of shell script is to ignore command errors and continue processing and report exit status of last command. If you want to exit on error and report its status we can use -e option.

Yes you can very easily downloads Files from the remote Url Using this code. This Code is working Fine for Me.

func DownlondFromUrl(){
   // Create destination URL 
let documentsUrl:URL =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("downloadedFile.jpg")

//Create URL to the source file you want to download
let fileURL = URL(string: "https://s3.amazonaws.com/learn-swift/IMG_0001.JPG")

let sessionConfig = URLSessionConfiguration.default
let session = URLSession(configuration: sessionConfig)

let request = URLRequest(url:fileURL!)

let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
    if let tempLocalUrl = tempLocalUrl, error == nil {
        // Success
        if let statusCode = (response as? HTTPURLResponse)?.statusCode {
            print("Successfully downloaded. Status code: \(statusCode)")
        }

        do {
            try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
        } catch (let writeError) {
            print("Error creating a file \(destinationFileUrl) : \(writeError)")
        }

    } else {
        print("Error took place while downloading a file. Error description: %@", error?.localizedDescription);
    }
}
task.resume()
}

Well, if there's anyone out there on a shared hosting and with no access to php.ini file, you can set this line of code at the very top of your PHP files:

ini_set('always_populate_raw_post_data', -1);

Works more of the same. I hope it saves someone some debugging time :)

Its Simple Way To Pass Header

function get_data($url) {

$ch = curl_init();
$timeout = 5;
$username = 'c4f727b9646045e58508b20ac08229e6';        // Put Username 
$password = '';                                        // Put Password
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");    // Add This Line
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$url = "https://storage.scrapinghub.com/items/397187/2/127";
$data = get_data($url);
echo '<pre>';`print_r($data_json);`die;    // For Print Value

Check My JSON Value

Here dataTpe is "json" so, data/reqParam must be in the form of string while calling API, many as much as object as you want but at last inside $.ajax's data stringify the object.

             let person= {  name: 'john',
                age: 22
            };

           var personStr = JSON.stringify(person); 

            $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: JSON.stringify( { param1: personStr } ),
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

OR,

       $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: personStr,
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });
