There are a few good answers posted here, but I think you can simplify your code and skip the check for inputElement.selectionStart support: it is not supported only on IE8 and earlier (see documentation) which represents less than 1% of the current browser usage.

var input = document.getElementById('myinput'); // or $('#myinput')[0]
var caretPos = input.selectionStart;

// and if you want to know if there is a selection or not inside your input:

if (input.selectionStart != input.selectionEnd)
{
    var selectionValue =
    input.value.substring(input.selectionStart, input.selectionEnd);
}

The code below can be used for taking a photo and for picking a photo. Just show a dialog with two options and upon selection, use the appropriate code.

To take picture from camera:

Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);//zero can be replaced with any action code (called requestCode)

To pick photo from gallery:

Intent pickPhoto = new Intent(Intent.ACTION_PICK,
           android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);//one can be replaced with any action code

onActivityResult code:

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 
    switch(requestCode) {
    case 0:
        if(resultCode == RESULT_OK){  
            Uri selectedImage = imageReturnedIntent.getData();
            imageview.setImageURI(selectedImage);
        }

    break; 
    case 1:
        if(resultCode == RESULT_OK){  
            Uri selectedImage = imageReturnedIntent.getData();
            imageview.setImageURI(selectedImage);
        }
    break;
    }
}

Finally add this permission in the manifest file:

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

All the answers seem pretty old :) I'd prefer CSS grid for a better page layout (absolute divs can be overridden by other divs in the page.)

<div class="container">
  <div class="inner" style="background-color: white;"></div>
  <div class="inner" style="background-color: red;"></div>
  <div class="inner" style="background-color: green;"></div>
  <div class="inner" style="background-color: blue;"></div>
  <div class="inner" style="background-color: purple;"></div>
  <div class="inner no-display" style="background-color: black;"></div>
</div>

<style>
.container {
  width: 300px;
  height: 300px;
  margin: 0 auto;
  background-color: yellow;
  display: grid;
  place-items: center;
  grid-template-areas:
                  "inners";
}

.inner {
  grid-area: inners;
  height: 100px;
  width: 100px;
}

.no-display {
  display: none;
}
</style>

Here's a working link

what worked for me is just define the variable outside this function of your.

Just before main function declare i.e.

Double price;
public static void main(String []args(){
--------
--------
}

PK - Primary Key

NN - Not Null

BIN - Binary (stores data as binary strings. There is no character set so sorting and comparison is based on the numeric values of the bytes in the values.)

UN - Unsigned (non-negative numbers only. so if the range is -500 to 500, instead its 0 - 1000, the range is the same but it starts at 0)

UQ - Create/remove Unique Key

ZF - Zero-Filled (if the length is 5 like INT(5) then every field is filled with 0’s to the 5th digit. 12 = 00012, 400 = 00400, etc. )

AI - Auto Increment

G - Generated column. i.e. value generated by a formula based on the other columns

You can use [(ngModel)], but you'll need to update your value to [value] otherwise the value is evaluating as a string. It would look like this:

<label>This rule is true if:</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="true" [(ngModel)]="rule.mode">
</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="false" [(ngModel)]="rule.mode">
</label>

If rule.mode is true, then that radio is selected. If it's false, then the other.

The difference really comes down to the value. value="true" really evaluates to the string 'true', whereas [value]="true" evaluates to the boolean true.

First, we're talking about packaging a Node.js app for workshops, demos, etc. where it can be handy to have an app "just running" without the need for the end user to care about installation and dependencies.

You can try the following setup:

1. Get your apps source code
2. npm install all dependencies (via package.json) to the local node_modules directory. It is important to perform this step on each platform you want to support separately, in case of binary dependencies.
3. Copy the Node.js binary – node.exe on Windows, (probably) /usr/local/bin/node on OS X/Linux to your project's root folder. On OS X/Linux you can find the location of the Node.js binary with which node.

For Windows:
Create a self extracting archive, 7zip_extra supports a way to execute a command right after extraction, see: http://www.msfn.org/board/topic/39048-how-to-make-a-7-zip-switchless-installer/.

For OS X/Linux:
You can use tools like makeself or unzipsfx (I don't know if this is compiled with CHEAP_SFX_AUTORUN defined by default).

These tools will extract the archive to a temporary directory, execute the given command (e.g. node app.js) and remove all files when finished.

If what you need is to post data instead of adding the info in the url.

public Request post(String url, String username, String password, 
      Listener listener, ErrorListener errorListener) {
  JSONObject params = new JSONObject();
  params.put("user", username);
  params.put("pass", password);
  Request req = new Request(
     Method.POST,
     url,
     params.toString(),
     listener,
     errorListener
  );

  return req;
}

If what you want to do is edit the headers in the request this is what you want to do:

// could be any class that implements Map
Map<String, String> mHeaders = new ArrayMap<String, String>();
mHeaders.put("user", USER);
mHeaders.put("pass", PASSWORD);
Request req = new Request(url, postBody, listener, errorListener) {
  public Map<String, String> getHeaders() {
    return mHeaders;
  }
}

If using javascript is allowed, you can set the display property to an empty string. This will cause it to use the default for that particular element.

var element = document.querySelector('span.selector');

// Set display to empty string to use default for that element
element.style.display = '';

Here is a link to a jsbin.

This is nice because you don't have to worry about the different types of display to revert to (block, inline, inline-block, table-cell, etc).

But, it requires javascript, so if you are looking for a css-only solution, then this is not the solution for you.

Note: This overrides inline styles, but not styles set in css

you can use group and max:

db.getCollection('kids').aggregate([
    {
        $group: {
            _id: null,
            maxQuantity: {$max: "$age"}
        }
    }
])

Here is a little lib to load javascript and CSS files dynamically:

https://github.com/todotresde/javascript-loader

I guess is usefull to load css and js files in order and dynamically.

Support to extend to load any lib you want, and not just the main file, you can use it to load custom files.

I.E.:

<html>
<head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script src="scripts/javascript-loader.js" type="text/javascript" charset="utf-8" ></script>    
    <script type="text/javascript">
        $(function() {

            registerLib("threejs", test);

            function test(){
                console.log(THREE);
            }

            registerLib("tinymce", draw);

            function draw(){
                tinymce.init({selector:'textarea'});
            }

        }); 
    </script>
</head>
<body>
    <textarea>Your content here.</textarea>
</body>

Based on the idea of B Hart's answer, here's my version of a function that searches for a value in a range, and returns all found ranges (cells):

Function FindAll(ByVal rng As Range, ByVal searchTxt As String) As Range
    Dim foundCell As Range
    Dim firstAddress
    Dim rResult As Range
    With rng
        Set foundCell = .Find(What:=searchTxt, _
                              After:=.Cells(.Cells.Count), _
                              LookIn:=xlValues, _
                              LookAt:=xlWhole, _
                              SearchOrder:=xlByRows, _
                              SearchDirection:=xlNext, _
                              MatchCase:=False)
        If Not foundCell Is Nothing Then
            firstAddress = foundCell.Address
            Do
                If rResult Is Nothing Then
                    Set rResult = foundCell
                Else
                    Set rResult = Union(rResult, foundCell)
                End If
                Set foundCell = .FindNext(foundCell)
            Loop While Not foundCell Is Nothing And foundCell.Address <> firstAddress
        End If
    End With

    Set FindAll = rResult
End Function

To search for a value in the whole workbook:

Dim wSh As Worksheet
Dim foundCells As Range
For Each wSh In ThisWorkbook.Worksheets
    Set foundCells = FindAll(wSh.UsedRange, "YourSearchString")
    If Not foundCells Is Nothing Then
        Debug.Print ("Results in sheet '" & wSh.Name & "':")
        Dim cell As Range
        For Each cell In foundCells
            Debug.Print ("The value has been found in cell: " & cell.Address)
        Next
    End If
Next

You can return a number by using this trick:
not recommended

[a] + b - 0

Example :

let output = [5] + 6 - 0;
console.log(output); // 56
console.log(typeof output); // number

This link explains how to apply a cell style to a range of cells: http://msdn.microsoft.com/en-us/library/f1hh9fza.aspx

See this snippet:

Microsoft.Office.Tools.Excel.NamedRange rangeStyles =
this.Controls.AddNamedRange(this.Range["A1"], "rangeStyles");

rangeStyles.Value2 = "'Style Test";
rangeStyles.Style = "NewStyle";
rangeStyles.Columns.AutoFit();

In Angular $http case, the success() and error() function will have response object been unwrapped, so the callback signature would be like $http(...).success(function(data, status, headers, config))

for then(), you probably will deal with the raw response object. such as posted in AngularJS $http API document

$http({
        url: $scope.url,
        method: $scope.method,
        cache: $templateCache
    })
    .success(function(data, status) {
        $scope.status = status;
        $scope.data = data;
    })
    .error(function(data, status) {
        $scope.data = data || 'Request failed';
        $scope.status = status;
    });

The last .catch(...) will not need unless there is new error throw out in previous promise chain.

This lifecycle method is invoked as soon as the updating happens. The most common use case for the componentDidUpdate() method is updating the DOM in response to prop or state changes.

You can call setState() in this lifecycle, but keep in mind that you will need to wrap it in a condition to check for state or prop changes from previous state. Incorrect usage of setState() can lead to an infinite loop. Take a look at the example below that shows a typical usage example of this lifecycle method.

componentDidUpdate(prevProps) {
 //Typical usage, don't forget to compare the props
 if (this.props.userName !== prevProps.userName) {
   this.fetchData(this.props.userName);
 }
}

Notice in the above example that we are comparing the current props to the previous props. This is to check if there has been a change in props from what it currently is. In this case, there won’t be a need to make the API call if the props did not change.

For more info, refer to the official docs:

Bit heavy because of using pandas but works:

import pandas as pd
pd.to_datetime(msec_from_java, unit='ms').to_pydatetime()

Could use sprintf to accomplish this:

awk '{str = sprintf("%s %s", $1, $2)} END {print str}' file

Corrected a few things and added an alternative select - delete as appropriate.

Someone here suggested using eval() to remove the quotes from a string. Don't do that, that's just begging for code injection.

Another way to do this that I don't see listed here is using:

let message = JSON.stringify(your_json_here); // "Hello World"
console.log(JSON.parse(message))              // Hello World

One very quick way around this is, when you're viewing the "Your connection is not private" screen:

type badidea

type thisisunsafe (credit to The Java Guy for finding the new passphrase)

That will allow the security exception when Chrome is otherwise not allowing the exception to be set via clickthrough, e.g. for this HSTS case.

This is only recommended for local connections and local-network virtual machines, obviously, but it has the advantage of working for VMs being used for development (e.g. on port-forwarded local connections) and not just direct localhost connections.

Note: the Chrome developers have changed this passphrase in the past, and may do so again. If badidea ceases to work, please leave a note here if you learn the new passphrase. I'll try to do the same.

Edit: as of 30 Jan 2018 this passphrase appears to no longer work.

If I can hunt down a new one I'll post it here. In the meantime I'm going to take the time to set up a self-signed certificate using the method outlined in this stackoverflow post:

How to create a self-signed certificate with openssl?

Edit: as of 1 Mar 2018 and Chrome Version 64.0.3282.186 this passphrase works again for HSTS-related blocks on .dev sites.

Edit: as of 9 Mar 2018 and Chrome Version 65.0.3325.146 the badidea passphrase no longer works.

Edit 2: the trouble with self-signed certificates seems to be that, with security standards tightening across the board these days, they cause their own errors to be thrown (nginx, for example, refuses to load an SSL/TLS cert that includes a self-signed cert in the chain of authority, by default).

The solution I'm going with now is to swap out the top-level domain on all my .app and .dev development sites with .test or .localhost. Chrome and Safari will no longer accept insecure connections to standard top-level domains (including .app).

The current list of standard top-level domains can be found in this Wikipedia article, including special-use domains:

Wikipedia: List of Internet Top Level Domains: Special Use Domains

These top-level domains seem to be exempt from the new https-only restrictions:

• .local
• .localhost
• .test
• (any custom/non-standard top-level domain)

See the answer and link from codinghands to the original question for more information:

answer from codinghands

The solutions here are old and now deprecated: https://github.com/uuidjs/uuid#deep-requires-now-deprecated

Use this:

npm install uuid

//add these lines to your code
const { v4: uuidv4 } = require('uuid');
var your_uuid = uuidv4();
console.log(your_uuid);

After I tried algirdas' solution, my Windows crashed (Win 7 Pro 64bit) so I decided to try a different solution:

1. Start Run (Win+R)
2. Type cmd /K chcp 65001

You will get mostly what you want. To start it from the taskbar or anywhere else, make a shortcut (you can name it cmd.unicode.exe or whatever you like) and change its Target to C:\Windows\System32\cmd.exe /K chcp 65001.

Array indexes in JavaScript start at zero for the first item, so try this:

var firstArrayItem = myValues[0]

Of course, if you actually want the second item in the array at index 1, then it's myValues[1].

See Accessing array elements for more info.

Use:

  SELECT mt.name 
    FROM MY_TABLE mt
GROUP BY mt.name
  HAVING MAX(LENGTH(mt.name)) = 18

...assuming you know the length beforehand. If you don't, use:

  SELECT mt.name 
    FROM MY_TABLE mt
    JOIN (SELECT MAX(LENGTH(x.name) AS max_length
            FROM MY_TABLE x) y ON y.max_length = LENGTH(mt.name)

Proper jdbc call should look something like:

try { 
    Connection conn;
    Statement stmt;
    ResultSet rs; 

    try {
        conn = DriverManager.getConnection(myUrl,"",""); 
        stmt = conn.createStatement(); 
        rs = stmt.executeQuery(myQuery); 

        while ( rs.next() ) { 
            // process results
        } 

    } catch (SqlException e) { 
        System.err.println("Got an exception! "); 
        System.err.println(e.getMessage()); 
    } finally {
        // you should release your resources here
        if (rs != null) { 
            rs.close();
        }

        if (stmt != null) {
            stmt.close();
        }

        if (conn != null) {
            conn.close();
        }
    }
} catch (SqlException e) {
    System.err.println("Got an exception! "); 
    System.err.println(e.getMessage()); 
}

you can close connection (or statement) only after you get result from result set. Safest way is to do it in finally block. However close() could also throe SqlException, hence the other try-catch block.

To keep the change in file but not to commit I did this

git add .

git reset -- main/dontcheckmein.txt

git commit -m "commit message"

to verify the file is excluded do

git status

UPDATE

I found this interesting link how to solve your problem in PHP. I think you forgot to replace space by +as shown in the link.

I took this circle from http://images-mediawiki-sites.thefullwiki.org/04/1/7/5/6204600836255205.png as sample which looks like:

Next I put it through http://www.greywyvern.com/code/php/binary2base64 which returned me:

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEAAAABACAAAAACPAi4CAAAAB3RJTUUH1QEHDxEhOnxCRgAAAAlwSFlzAAAK8AAACvABQqw0mAAAAXBJREFUeNrtV0FywzAIxJ3+K/pZyctKXqamji0htEik9qEHc3JkWC2LRPCS6Zh9HIy/AP4FwKf75iHEr6eU6Mt1WzIOFjFL7IFkYBx3zWBVkkeXAUCXwl1tvz2qdBLfJrzK7ixNUmVdTIAB8PMtxHgAsFNNkoExRKA+HocriOQAiC+1kShhACwSRGAEwPP96zYIoE8Pmph9qEWWKcCWRAfA/mkfJ0F6dSoA8KW3CRhn3ZHcW2is9VOsAgoqHblncAsyaCgcbqpUZQnWoGTcp/AnuwCoOUjhIvCvN59UBeoPZ/AYyLm3cWVAjxhpqREVaP0974iVwH51d4AVNaSC8TRNNYDQEFdlzDW9ob10YlvGQm0mQ+elSpcCCBtDgQD7cDFojdx7NIeHJkqi96cOGNkfZOroZsHtlPYoR7TOp3Vmfa5+49uoSSRyjfvc0A1kLx4KC6sNSeDieD1AWhrJLe0y+uy7b9GjP83l+m68AJ72AwSRPN5g7uwUAAAAAElFTkSuQmCC

saved this string to base64 which I read from in my code.

var fs      = require('fs'),
data        = fs.readFileSync('base64', 'utf8'),
base64Data,
binaryData;

base64Data  =   data.replace(/^data:image\/png;base64,/, "");
base64Data  +=  base64Data.replace('+', ' ');
binaryData  =   new Buffer(base64Data, 'base64').toString('binary');

fs.writeFile("out.png", binaryData, "binary", function (err) {
    console.log(err); // writes out file without error, but it's not a valid image
});

I get a circle back, but the funny thing is that the filesize has changed :)...

END

When you read back image I think you need to setup headers

Take for example imagepng from PHP page:

<?php
$im = imagecreatefrompng("test.png");

header('Content-Type: image/png');

imagepng($im);
imagedestroy($im);
?>

I think the second line header('Content-Type: image/png');, is important else your image will not be displayed in browser, but just a bunch of binary data is shown to browser.

In Express you would simply just use something like below. I am going to display your gravatar which is located at http://www.gravatar.com/avatar/cabf735ce7b8b4471ef46ea54f71832d?s=32&d=identicon&r=PG and is a jpeg file when you curl --head http://www.gravatar.com/avatar/cabf735ce7b8b4471ef46ea54f71832d?s=32&d=identicon&r=PG. I only request headers because else curl will display a bunch of binary stuff(Google Chrome immediately goes to download) to console:

This is essentially the algorithm you described as "clunky", using idiomatic pandas methods. Note the duplicate row indices. Also, note that this won't give you the expected output if df1 and df2 have no overlapping row indices, i.e., if

In [93]: df1.index & df2.index
Out[93]: Int64Index([], dtype='int64')

In fact, it won't give the expected output if their row indices are not equal.

There are various ways to get a Set as:

    List<Integer> sourceList = new ArrayList();
    sourceList.add(1);
    sourceList.add(2);
    sourceList.add(3);
    sourceList.add(4);

    // Using Core Java
    Set<Integer> set1 = new HashSet<>(sourceList);  //needs null-check if sourceList can be null.

    // Java 8
    Set<Integer> set2 = sourceList.stream().collect(Collectors.toSet());
    Set<Integer> set3 = sourceList.stream().collect(Collectors.toCollection(HashSet::new));

    //Guava
    Set<Integer> set4 = Sets.newHashSet(sourceList);

    // Apache commons
    Set<Integer> set5 = new HashSet<>(4);
    CollectionUtils.addAll(set5, sourceList);

When we use Collectors.toSet() it returns a set and as per the doc:There are no guarantees on the type, mutability, serializability, or thread-safety of the Set returned. If we want to get a HashSet then we can use the other alternative to get a set (check set3).

In cases where the HTTPS/SSL connection is ended at the load balancer and all traffic is sent to instances on port 80, the following rule works to redirect non-secure traffic.

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Ensure the mod_rewrite module is loaded.

You can find the object in array with Alasql library:

var data = [ { name : "bob" , dinner : "pizza" }, { name : "john" , dinner : "sushi" },
     { name : "larry", dinner : "hummus" } ];

var res = alasql('SELECT * FROM ? WHERE dinner="sushi"',[data]);

Try this example in jsFiddle.

Change Integrated security to false in the connection string.

You can check/verify this by opening up the SQL management studio with the username/password you have and see if you can connect/open the database from there. NOTE! Could be a firewall issue as well.

.str.get

This is the simplest to specify string methods

# Setup
df = pd.DataFrame({'A': ['xyz', 'abc', 'foobar'], 'B': [123, 456, 789]})
df

        A    B
0     xyz  123
1     abc  456
2  foobar  789

df.dtypes

A    object
B     int64
dtype: object

For string (read:object) type columns, use

df['C'] = df['A'].str[0]
# Similar to,
df['C'] = df['A'].str.get(0)

.str handles NaNs by returning NaN as the output.

For non-numeric columns, an .astype conversion is required beforehand, as shown in @Ed Chum's answer.

# Note that this won't work well if the data has NaNs. 
# It'll return lowercase "n"
df['D'] = df['B'].astype(str).str[0]

df
        A    B  C  D
0     xyz  123  x  1
1     abc  456  a  4
2  foobar  789  f  7

List Comprehension and Indexing

There is enough evidence to suggest a simple list comprehension will work well here and probably be faster.

# For string columns
df['C'] = [x[0] for x in df['A']]

# For numeric columns
df['D'] = [str(x)[0] for x in df['B']]

df
        A    B  C  D
0     xyz  123  x  1
1     abc  456  a  4
2  foobar  789  f  7

If your data has NaNs, then you will need to handle this appropriately with an if/else in the list comprehension,

df2 = pd.DataFrame({'A': ['xyz', np.nan, 'foobar'], 'B': [123, 456, np.nan]})
df2

        A      B
0     xyz  123.0
1     NaN  456.0
2  foobar    NaN

# For string columns
df2['C'] = [x[0] if isinstance(x, str) else np.nan for x in df2['A']]

# For numeric columns
df2['D'] = [str(x)[0] if pd.notna(x) else np.nan for x in df2['B']]

        A      B    C    D
0     xyz  123.0    x    1
1     NaN  456.0  NaN    4
2  foobar    NaN    f  NaN

Let's do some timeit tests on some larger data.

df_ = df.copy()
df = pd.concat([df_] * 5000, ignore_index=True) 

%timeit df.assign(C=df['A'].str[0])
%timeit df.assign(D=df['B'].astype(str).str[0])

%timeit df.assign(C=[x[0] for x in df['A']])
%timeit df.assign(D=[str(x)[0] for x in df['B']])

12 ms ± 253 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
27.1 ms ± 1.38 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

3.77 ms ± 110 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
7.84 ms ± 145 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

List comprehensions are 4x faster.

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String) and class.getClassLoader().getResourceAsStream(String). This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).

MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!  
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!

Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String) in the past and haven't had any problems.

PS: I also posted this over here

I used MP4Box to decode the atom tags in the mp4. (MP4Box -v myfile.mp4) I also used ffmpeg to convert the mp41 to mp42. After comparing the differences and experimenting, I found that IE11 did not like that my original mp4 had two avC1 atoms inside stsd.

After deleting the duplicate avC1 in my original mp41 mp4, IE11 would play the mp4.

Yet another cause - I was trying to include a module in settings.gradle using

include ':MyModule'
project(':MyModule').projectDir = new File(settingsDir, '../../MyModule')

Only problem was, I had just imported the module from Eclipse an forgot to move the directory outside my application project, i.e. the path '../../MyModule' didn't exist.

redirect_to new_user_path(:id => 1, :contact_id => 3, :name => 'suleman')

On CentOS 7 and Python 3.4, the command is sudo yum install python34-tkinter

On Redhat 7.4 with Python 3.6, the command is sudo yum install rh-python36-python-tkinter

In most cases, it is enough just to hide the element, for example in this way:

export default class ErrorBoxComponent extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            isHidden: false
        }
    }

    dismiss() {
        this.setState({
            isHidden: true
        })
    }

    render() {
        if (!this.props.error) {
            return null;
        }

        return (
            <div data-alert className={ "alert-box error-box " + (this.state.isHidden ? 'DISPLAY-NONE-CLASS' : '') }>
                { this.props.error }
                <a href="#" className="close" onClick={ this.dismiss.bind(this) }>&times;</a>
            </div>
        );
    }
}

Or you may render/rerender/not render via parent component like this

export default class ParentComponent extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            isErrorShown: true
        }
    }

    dismiss() {
        this.setState({
            isErrorShown: false
        })
    }

    showError() {
        if (this.state.isErrorShown) {
            return <ErrorBox 
                error={ this.state.error }
                dismiss={ this.dismiss.bind(this) }
            />
        }

        return null;
    }

    render() {

        return (
            <div>
                { this.showError() }
            </div>
        );
    }
}

export default class ErrorBoxComponent extends React.Component {
    dismiss() {
        this.props.dismiss();
    }

    render() {
        if (!this.props.error) {
            return null;
        }

        return (
            <div data-alert className="alert-box error-box">
                { this.props.error }
                <a href="#" className="close" onClick={ this.dismiss.bind(this) }>&times;</a>
            </div>
        );
    }
}

Finally, there is a way to remove html node, but i really dont know is it a good idea. Maybe someone who knows React from internal will say something about this.

export default class ErrorBoxComponent extends React.Component {
    dismiss() {
        this.el.remove();
    }

    render() {
        if (!this.props.error) {
            return null;
        }

        return (
            <div data-alert className="alert-box error-box" ref={ (el) => { this.el = el} }>
                { this.props.error }
                <a href="#" className="close" onClick={ this.dismiss.bind(this) }>&times;</a>
            </div>
        );
    }
}

How about this?

$.each(someArray, function(i){
    if(someArray[i].name === 'Kristian') {
        someArray.splice(i,1);
        return false;
    }
});

var uniqueColors = (from dbo in database.MainTable 
                    where dbo.Property == true
                    select dbo.Color.Name).Distinct();

You can use SEPARATOR and ORDER BY inside the GROUP_CONCAT function in this way:

SELECT li.client_id, group_concat(li.percentage ORDER BY li.views ASC SEPARATOR ',') 
AS views, group_concat(li.percentage ORDER BY li.percentage ASC SEPARATOR ',') FROM li
GROUP BY client_id;

Command: ls -1 -d "$PWD/"*

This will give the absolute paths of the file like below.

[root@kubenode1 ssl]# ls -1 -d "$PWD/"*
/etc/kubernetes/folder/file-test-config.txt
/etc/kubernetes/folder/file-test.txt
/etc/kubernetes/folder/file-client.txt

(function(){
        $(".modal").on("hidden.bs.modal", function(){
            $(this).removeData();
        });
});

This is perfect solution to remove contact while hide/close bootstrap modal.

1NF: Only one value per column

2NF: All the non primary key columns in the table should depend on the entire primary key.

3NF: All the non primary key columns in the table should depend DIRECTLY on the entire primary key.

I have written an article in more detail over here

If you have to log all args or your method have one argument, you can simply use getArgs like described in previous answers.

If you have to log a specific arg, you can annoted it and then recover its value like this :

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.PARAMETER)
public @interface Data {
 String methodName() default "";
}

@Aspect
public class YourAspect {

 @Around("...")
 public Object around(ProceedingJoinPoint point) throws Throwable {
  Method method = MethodSignature.class.cast(point.getSignature()).getMethod();
  Object[] args = point.getArgs();
  StringBuilder data = new StringBuilder();
    Annotation[][] parameterAnnotations = method.getParameterAnnotations();
    for (int argIndex = 0; argIndex < args.length; argIndex++) {
        for (Annotation paramAnnotation : parameterAnnotations[argIndex]) {
            if (!(paramAnnotation instanceof Data)) {
                continue;
            }
            Data dataAnnotation = (Data) paramAnnotation;
            if (dataAnnotation.methodName().length() > 0) {
                Object obj = args[argIndex];
                Method dataMethod = obj.getClass().getMethod(dataAnnotation.methodName());
                data.append(dataMethod.invoke(obj));
                continue;
            }
            data.append(args[argIndex]);
        }
    }
 }
}

Examples of use :

public void doSomething(String someValue, @Data String someData, String otherValue) {
    // Apsect will log value of someData param
}

public void doSomething(String someValue, @Data(methodName = "id") SomeObject someData, String otherValue) {
    // Apsect will log returned value of someData.id() method
}

for me, (OSX) the problem was solved doing this:

brew install pkg-config

I met these warnings on mempcpy function. Man page says this function is a GNU extension and synopsis shows:

#define _GNU_SOURCE
#include <string.h>

When #define is added to my source before the #include, declarations for the GNU extensions are made visible and warnings disappear.

You can save image , save the file in your current directory application and move the file to any directory .

 Bitmap btm = new Bitmap(image.width,image.height);
    Image img = btm;
                        img.Save(@"img_" + x + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
                        FileInfo img__ = new FileInfo(@"img_" + x + ".jpg");
                        img__.MoveTo("myVideo\\img_" + x + ".jpg");

Here's an example of two applications in one html page and two conrollers in one application :

    <div ng-app = "myapp">
      <div  ng-controller = "C1" id="D1">
         <h2>controller 1 in app 1 <span id="titre">{{s1.title}}</span> !</h2>
      </div>

      <div  ng-controller = "C2" id="D2">
         <h2>controller 2 in app 1 <span id="titre">{{s2.valeur}}</span> !</h2>
      </div>
    </div>
    <script>
        var A1 = angular.module("myapp", [])

        A1.controller("C1", function($scope) {
            $scope.s1 = {};
            $scope.s1.title = "Titre 1";
         });

        A1.controller("C2", function($scope) {
            $scope.s2 = {};
            $scope.s2.valeur = "Valeur 2";
         });
    </script>

    <div ng-app="toapp" ng-controller="C1" id="App2">
        <br>controller 1 in app 2
        <br>First Name: <input type = "text" ng-model = "student.firstName">
        <br>Last Name : <input type="text" ng-model="student.lastName">
        <br>Hello : {{student.fullName()}}
        <br>
    </div>

    <script>
        var A2 = angular.module("toapp", []);
        A2.controller("C1", function($scope) {
            $scope.student={
                firstName:"M",
                lastName:"E",
                fullName:function(){
                    var so=$scope.student;
                    return so.firstName+" "+so.lastName;
                }
            };
        });
        angular.bootstrap(document.getElementById("App2"), ['toapp']);
    </script>

If you're using jQuery then there are a few different ways to set the disabled attribute.

var $element = $(...);
    $element.prop('disabled', true);
    $element.attr('disabled', true); 

    // The following do not require jQuery
    $element.get(0).disabled = true;
    $element.get(0).setAttribute('disabled', true);
    $element[0].disabled = true;
    $element[0].setAttribute('disabled', true);

Try... for YUI

Dom.get("gadget_url").set("value","");

with normal Javascript

document.getElementById('gadget_url').value = '';

with JQuery

$("#gadget_url").val("");

You can improve the speed of your code if you restrict the items jQuery will look at.

Use the selector :input instead of * to achieve it.

$('#divId :input').serialize()

This will make your code faster because the list of items is shorter.

I think this is the most reliable way to get the desktop path which isn't always the same as the username.

MsgBox CreateObject("WScript.Shell").specialfolders("Desktop")

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

The solution is simple:
log in as root
and after:

su - postgres

psql

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

That's really an informational message.

Likely, you're doing OPTIMIZE on an InnoDB table (table using the InnoDB storage engine, rather than the MyISAM storage engine).

InnoDB doesn't support the OPTIMIZE the way MyISAM does. It does something different. It creates an empty table, and copies all of the rows from the existing table into it, and essentially deletes the old table and renames the new table, and then runs an ANALYZE to gather statistics. That's the closest that InnoDB can get to doing an OPTIMIZE.

The message you are getting is basically MySQL server repeating what the InnoDB storage engine told MySQL server:

Table does not support optimize is the InnoDB storage engine saying...

"I (the InnoDB storage engine) don't do an OPTIMIZE operation like my friend (the MyISAM storage engine) does."

"doing recreate + analyze instead" is the InnoDB storage engine saying...

"I have decided to perform a different set of operations which will achieve an equivalent result."

Thanks so much Jason Pan for suggesting that method. The thread1 if statement is not atomic, so that while that statement executes, it's possible for thread2 to intrude on thread1, allowing non-reachable code to be reached. I've organized ideas from the prior posts into a complete demonstration program (below) that I ran with Python 2.7.

With some thoughtful analysis I'm sure we could gain further insight, but for now I think it's important to demonstrate what happens when non-atomic behavior meets threading.

# ThreadTest01.py - Demonstrates that if non-atomic actions on
# global variables are protected, task can intrude on each other.
from threading import Thread
import time

# global variable
a = 0; NN = 100

def thread1(threadname):
    while True:
      if a % 2 and not a % 2:
          print("unreachable.")
    # end of thread1

def thread2(threadname):
    global a
    for _ in range(NN):
        a += 1
        time.sleep(0.1)
    # end of thread2

thread1 = Thread(target=thread1, args=("Thread1",))
thread2 = Thread(target=thread2, args=("Thread2",))

thread1.start()
thread2.start()

thread2.join()
# end of ThreadTest01.py

As predicted, in running the example, the "unreachable" code sometimes is actually reached, producing output.

Just to add, when I inserted a lock acquire/release pair into thread1 I found that the probability of having the "unreachable" message print was greatly reduced. To see the message I reduced the sleep time to 0.01 sec and increased NN to 1000.

With a lock acquire/release pair in thread1 I didn't expect to see the message at all, but it's there. After I inserted a lock acquire/release pair also into thread2, the message no longer appeared. In hind signt, the increment statement in thread2 probably also is non-atomic.

How about something like:

includes = $(wildcard include/*.h)

%.o: %.c ${includes}
    gcc -Wall -Iinclude ...

You could also use the wildcards directly, but I tend to find I need them in more than one place.

Note that this only works well on small projects, since it assumes that every object file depends on every header file.

Both i++ and ++i are short-hand for i = i + 1.

In addition to changing the value of i, they also return the value of i, either before adding one (i++) or after adding one (++i).

In a loop the third component is a piece of code that is executed after each iteration.

for (int i=0; i<10; i++)

The value of that part is not used, so the above is just the same as

for(int i=0; i<10; i = i+1)

or

for(int i=0; i<10; ++i)

Where it makes a difference (between i++ and ++i )is in these cases

while(i++ < 10)

for (int i=0; i++ < 10; )

An example, just to make this a 15 seconds answer -

Say you have "styles.xaml" in a WPF library named "common" and you want to use it from your main application project:

1. Add a reference from the main project to "common" project
2. Your app.xaml should contain:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/Common;component/styles.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

For localhost - I forgot to write in C:\Windows\System32\drivers\etc\hosts

127.0.0.1 localhost

Also removed proxy_pass http://127.0.0.1; from other server in ngnix.conf

Solution for React-native >V0.60

You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.

Open a terminal and type ipconfig getifaddr en0 For MAC

Make sure your laptop and your phone are on the same Wi-Fi network. Open your React Native app on your device.

You'll see a red screen with an error. This is OK. The following steps will fix that.

1. Open the in-app Developer menu. shake your phone or press CMD/ctrl + M
2. Click on Settings
3. click on Debug server host & port for device
4. On popup Type your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
5. Go back to the Developer menu and select Reload.

DONE

You can use a subselect in your from query (untested and not sure which is faster):

SELECT Grade, COUNT(*) / TotalRows
FROM (SELECT Grade, COUNT(*) As TotalRows
      FROM myTable) Grades
GROUP BY Grade, TotalRows

Or

SELECT Grade, SUM(PartialCount)
FROM (SELECT Grade, 1/COUNT(*) AS PartialCount
      FROM myTable) Grades
GROUP BY Grade

Or

SELECT Grade, GradeCount / SUM(GradeCount)
FROM (SELECT Grade, COUNT(*) As GradeCount
      FROM myTable
      GROUP BY Grade) Grades

You can also use a stored procedure (apologies for the Firebird syntax):

SELECT COUNT(*)
FROM myTable
INTO :TotalCount;

FOR SELECT Grade, COUNT(*)
FROM myTable
GROUP BY Grade
INTO :Grade, :GradeCount
DO
BEGIN
    Percent = :GradeCount / :TotalCount;
    SUSPEND;
END

cat | /my/bash/script

Enables one to type multiple lines into a program, without that input being saved in history, nor visible in ps. Just press Ctrl + C when finished typing to end cat.

The problem is that once the IsUserNameFocused is set to true, it will never be false. This solves it by handling the GotFocus and LostFocus for the FrameworkElement.

I was having trouble with the source code formatting so here is a link

Use this code between two words:

& vbCrLf &

Using this, the next word displays on the next line.

I'll have a go at this complicated subject.

What is origin?

The origin itself is the name of a host (scheme, hostname, and port) i.g. https://www.google.com or could be a locally opened file file:// etc.. It is where something (i.g. a web page) originated from. When you open your web browser and go to https://www.google.com, the origin of the web page that is displayed to you is https://www.google.com. You can see this in Chrome Dev Tools under Security:

The same applies for if you open a local HTML file via your file explorer (which is not served via a server):

What has this got to do with CORS issues?

When you open your browser and go to https://website.com, that website will have the origin of https://website.com. This website will most likely only fetch images, icons, js files and do API calls towards https://website.com, basically it is calling the same server as it was served from. It is doing calls to the same origin.

If you open your web browser and open a local HTML file and in that html file there is javascript which wants to do a request to google for example, you get the following error:

The same-origin policy tells the browser to block cross-origin requests. In this instance origin null is trying to do a request to https://www.google.com (a cross-origin request). The browser will not allow this because of the CORS Policy which is set and that policy is that cross-origin requests is not allowed.

Same applies for if my page was served from a server on localhost:

Localhost server example

If we host our own localhost API server running on localhost:3000 with the following code:

const express = require('express')
const app = express()
 
app.use(express.static('public'))

app.get('/hello', function (req, res) {
    // res.header("Access-Control-Allow-Origin", "*");
    res.send('Hello World');
})
 
app.listen(3000, () => {
    console.log('alive');
})

And open a HTML file (that does a request to the localhost:3000 server) directory from the file explorer the following error will happen:

Since the web page was not served from the localhost server on localhost:3000 and via the file explorer the origin is not the same as the server API origin, hence a cross-origin request is being attempted. The browser is stopping this attempt due to CORS Policy.

But if we uncomment the commented line:

const express = require('express')
const app = express()
 
app.use(express.static('public'))

app.get('/hello', function (req, res) {
    res.header("Access-Control-Allow-Origin", "*");
    res.send('Hello World');
})
 
app.listen(3000, () => {
    console.log('alive');
})

And now try again:

It works, because the server which sends the HTTP response included now a header stating that it is ok for cross-origin requests to happen to the server, this means the browser will let it happen, hence no error.

How to fix things

1. Serve the page from the same origin as where the requests you are making reside (same host).
2. Allow the server to receive cross-origin requests by explicitly stating it in the response headers.
3. Don't use a browser. Use cURL for example, it doesn't care about CORS Policies like browsers do and will get you what you want.

Example flow

Following is taken from: https://web.dev/cross-origin-resource-sharing/#how-does-cors-work

Remember, the same-origin policy tells the browser to block cross-origin requests. When you want to get a public resource from a different origin, the resource-providing server needs to tell the browser "This origin where the request is coming from can access my resource". The browser remembers that and allows cross-origin resource sharing.

• Step 1: client (browser) request When the browser is making a cross-origin request, the browser adds an Origin header with the current origin (scheme, host, and port).

• Step 2: server response On the server side, when a server sees this header, and wants to allow access, it needs to add an Access-Control-Allow-Origin header to the response specifying the requesting origin (or * to allow any origin.)

• Step 3: browser receives response When the browser sees this response with an appropriate Access-Control-Allow-Origin header, the browser allows the response data to be shared with the client site.

So I had this issue with Adobe Reader 9.0. Somehow the program forgot to open on my right monitor and was consistently opening on my left monitor. Most programs allow you to drag it over, maximize the screen, and then close it out and it will remember. Well, with Adobe, I had to drag it over and then close it before maximizing it, in order for Windows to remember which screen to open it in next time. Once you set it to the correct monitor, then you can maximize it. I think this is stupid, since almost all windows programs remember it automatically without try to rig a way for XP to remember.

You can't revert a md5 password.(in any language)

But you can:

give to the user a new one.

check in some rainbow table to maybe retrieve the old one.

I am using the following construct, although you might want to avoid shell=True. This gives you the output and error message for any command, and the error code as well:

process = subprocess.Popen(cmd, shell=True,
                           stdout=subprocess.PIPE, 
                           stderr=subprocess.PIPE)

# wait for the process to terminate
out, err = process.communicate()
errcode = process.returncode

You can customize material styles by setting different color properties. For example custom application theme

<style name="CustomAppTheme" parent="Theme.AppCompat">
    <item name="android:textColorPrimaryDisableOnly">#00838f</item>
    <item name="colorAccent">#e91e63</item>

Custom switch theme

<style name="MySwitch" parent="@style/Widget.AppCompat.CompoundButton.Switch">
    <item name="android:textColorPrimaryDisableOnly">#b71c1c</item>
    <item name="android:colorControlActivated">#1b5e20</item>
    <item name="android:colorForeground">#f57f17</item>

IIS 6.0 and previous versions :

ASP.NET integrated with IIS via an ISAPI extension, a C API ( C Programming language based API ) and exposed its own application and request processing model.

This effectively exposed two separate server( request / response ) pipelines, one for native ISAPI filters and extension components, and another for managed application components. ASP.NET components would execute entirely inside the ASP.NET ISAPI extension bubble AND ONLY for requests mapped to ASP.NET in the IIS script map configuration.

Requests to non ASP.NET content types:- images, text files, HTML pages, and script-less ASP pages, were processed by IIS or other ISAPI extensions and were NOT visible to ASP.NET.

The major limitation of this model was that services provided by ASP.NET modules and custom ASP.NET application code were NOT available to non ASP.NET requests

What's a SCRIPT MAP ?

Script maps are used to associate file extensions with the ISAPI handler that executes when that file type is requested. The script map also has an optional setting that verifies that the physical file associated with the request exists before allowing the request to be processed

A good example can be seen here

IIS 7 and above

IIS 7.0 and above have been re-engineered from the ground up to provide a brand new C++ API based ISAPI.

IIS 7.0 and above integrates the ASP.NET runtime with the core functionality of the Web Server, providing a unified(single) request processing pipeline that is exposed to both native and managed components known as modules ( IHttpModules )

What this means is that IIS 7 processes requests that arrive for any content type, with both NON ASP.NET Modules / native IIS modules and ASP.NET modules providing request processing in all stages This is the reason why NON ASP.NET content types (.html, static files ) can be handled by .NET modules.

• You can build new managed modules (IHttpModule) that have the ability to execute for all application content, and provided an enhanced set of request processing services to your application.
• Add new managed Handlers ( IHttpHandler)

I wanted something pretty close to this - the moment a user picks an item, even by just hitting the arrow keys to one (focus), I want that data item attached to the tag in question. When they type again without picking another item, I want that data cleared.

(function() {
    var lastText = '';

    $('#MyTextBox'), {
        source: MyData
    })
    .on('autocompleteselect autocompletefocus', function(ev, ui) {
        lastText = ui.item.label;
        jqTag.data('autocomplete-item', ui.item);
    })
    .keyup(function(ev) {
        if (lastText != jqTag.val()) {
            // Clear when they stop typing
            jqTag.data('autocomplete-item', null);

            // Pass the event on as autocompleteclear so callers can listen for select/clear
            var clearEv = $.extend({}, ev, { type: 'autocompleteclear' });
            return jqTag.trigger(clearEv);
    });
})();

With this in place, 'autocompleteselect' and 'autocompletefocus' still fire right when you expect, but the full data item that was selected is always available right on the tag as a result. 'autocompleteclear' now fires when that selection is cleared, generally by typing something else.

You should consider (temporarily) disabling the constraint before you completely delete it.

If you look at the table creation TSQL you will see something like:

ALTER TABLE [dbo].[dbAccounting] CHECK CONSTRAINT [FK_some_FK_constraint]

You can run

ALTER TABLE [dbo].[dbAccounting] NOCHECK CONSTRAINT [FK_some_FK_constraint]

... then insert/update a bunch of values that violate the constraint, and then turn it back on by running the original CHECK statement.

My json file was formatted exactly as the one in the question but none of the solutions here worked out. Finally I found a workaround on another Stackoverflow thread. Since this post is the first link in Google search, I put the that answer here so that other people come to this post in the future will find it more easily.

As it's been said there the valid json file needs "[" in the beginning and "]" in the end of file. Moreover, after each json item instead of "}" there must be a "},". All brackets without quotations! This piece of code just modifies the malformed json file into its correct format.

This line solved my same problem in postgresql:

SELECT DATE_PART('year', column_name::date) from tableName;

If you want month, then simply replacing year with month solves that as well and likewise.

It may or may not be the case that there is only one developer on this branch, that is now (after the rebase) not inline with the origin/feature.

As such I would suggest to use the following sequence:

git rebase master
git checkout -b feature_branch_2
git push origin feature_branch_2

Yeah, new branch, this should solve this without a --force, which I think generally is a major git drawback.

It comes from the era of Line Printers and green-striped fan-fold paper.

Trust me, you ain't gonna need it...

1. Do you mean that you want to center it vertically or horizontally? You said you specified the height to 800 pixels, and wanted the div not to stretch when the width was greater than that...

2. To center horizontally, you can use the margin: auto; attribute in CSS. Also, you'll have to make sure that the body and html elements don't have any margin or padding:

html, body { margin: 0; padding: 0; }
#centeredDiv { margin-right: auto; margin-left: auto; width: 800px; }

When I canceled the dialog git asked me for login and password in the command line and it worked fine.

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

Private Sub cmdInsertRow_Click()

    Dim lRow As Long

    lRow = Selection.Row()
    lRsp = MsgBox("Insert New row above " & lRow & "?", _
            vbQuestion + vbYesNo)
    If lRsp <> vbYes Then Exit Sub

    Rows(lRow).Select
    Selection.Copy
    Rows(lRow + 1).Select
    Selection.Insert Shift:=xlDown
    Application.CutCopyMode = False

   'Paste formulas and conditional formatting in new row created
    Rows(lRow).PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone

End Sub

This is what I use. Tested and working,

You can use the following code:

return RedirectToAction("Index", "Home");

See RedirectToAction

In the opening tag of your form, set an action attribute like so:

<form id="contactForm" action="#">

You should put all your words into some kind of Collection or List and then call it like this:

var searchFor = new List<string>();
searchFor.Add("pineapple");
searchFor.Add("mango");

bool containsAnySearchString = searchFor.Any(word => compareString.Contains(word));

If you need to make a case or culture independent search you should call it like this:

bool containsAnySearchString = 
   searchFor.Any(word => compareString.IndexOf
     (word, StringComparison.InvariantCultureIgnoreCase >= 0);

More accurately anything that is not 0 is true.

So 1 is true, but so is 2, 3 ... etc.

Here it is:

$filename = “c:\scripts_scott\test9999.xls”
$smtpserver = “smtp.gmail.com”
$msg = New-Object Net.Mail.MailMessage
$att = New-Object Net.Mail.Attachment($filename)
$smtp = New-Object Net.Mail.SmtpClient($smtpServer )
$smtp.EnableSsl = $True
$smtp.Credentials = New-Object System.Net.NetworkCredential(“username”, “password_here”); # Put username without the @GMAIL.com or – @gmail.com
$msg.From = “[email protected]”
$msg.To.Add(”[email protected]”)
$msg.Subject = “Monthly Report”
$msg.Body = “Good MorningATTACHED”
$msg.Attachments.Add($att)
$smtp.Send($msg)

Let me know if it helps you San. Also use the send-mailmessage also at Www.techjunkie.tv

For that way also that I think is way better and pure to use.

Common Dropdown operation (Get, Set, Add, Remove) using jQuery

It should be,

*/15 * * * *  your_command_or_whatever

while IFS='=' read -r name value ; do
    # Print line if found variable
    sed -n '/${'"${name}"'}/p' docker-compose.yml
    # Replace variable with value. 
    sed -i 's|${'"${name}"'}|'"${value}"'|' docker-compose.yml
done < <(env)

Note: Variable name or value should not contain "|", because it is used as a delimiter.

There is none when it comes to file extensions. Your bundler/transpiler/whatever takes care of resolving what type of file contents there is.

There are however some other considerations when deciding what to put into a .js or a .jsx file type. Since JSX isn't standard JavaScript one could argue that anything that is not "plain" JavaScript should go into its own extensions ie., .jsx for JSX and .ts for TypeScript for example.

This approach 100% working

Just do these simple step:

• Exit Android Studio
• Rename the main project folder from your explorer
• Open Android Studio and Open your project
• Rebuild and Enjoy.

It has already been mentioned how to remove a single element from a list and which advantages the different methods have. Note, however, that removing multiple elements has some potential for errors:

>>> l = [0,1,2,3,4,5,6,7,8,9]
>>> indices=[3,7]
>>> for i in indices:
...     del l[i]
... 
>>> l
[0, 1, 2, 4, 5, 6, 7, 9]

Elements 3 and 8 (not 3 and 7) of the original list have been removed (as the list was shortened during the loop), which might not have been the intention. If you want to safely remove multiple indices you should instead delete the elements with highest index first, e.g. like this:

>>> l = [0,1,2,3,4,5,6,7,8,9]
>>> indices=[3,7]
>>> for i in sorted(indices, reverse=True):
...     del l[i]
... 
>>> l
[0, 1, 2, 4, 5, 6, 8, 9]

The accepted answer is fine if you can use lookarounds. However, there is also another approach to solve this problem.

If we look at the widely proposed regex for this question:

.*[^a]$

We will find that it almost works. It does not accept an empty string, which might be a little inconvinient. However, this is a minor issue when dealing with just a one character. However, if we want to exclude whole string, e.g. "abc", then:

.*[^a][^b][^c]$

won't do. It won't accept ac, for example.

There is an easy solution for this problem though. We can simply say:

.{,2}$|.*[^a][^b][^c]$

or more generalized version:

.{,n-1}$|.*[^firstchar][^secondchar]$ where n is length of the string you want forbid (for abc it's 3), and firstchar, secondchar, ... are first, second ... nth characters of your string (for abc it would be a, then b, then c).

This comes from a simple observation that a string that is shorter than the text we won't forbid can not contain this text by definition. So we can either accept anything that is shorter("ab" isn't "abc"), or anything long enough for us to accept but without the ending.

Here's an example of find that will delete all files that are not .jpg:

find . -regex '.{,3}$|.*[^.][^j][^p][^g]$' -delete

Just to add to RichieHindle's answer, check out Floatutorial, which walks you through how CSS floating and clearing works.

1. Build a dynamic SQL using sys.tables and sys.columns to perform the search (example here).

2. Use any program that have this function. An example of this is SQL Workbench (free).

I used Ctrl+Click to click the submit button and navigate through the form as usual.

What parsers and lexers have in common:

1. They read symbols of some alphabet from their input.

   • Hint: The alphabet doesn't necessarily have to be of letters. But it has to be of symbols which are atomic for the language understood by parser/lexer.
   • Symbols for the lexer: ASCII characters.
   • Symbols for the parser: the particular tokens, which are terminal symbols of their grammar.

2. They analyse these symbols and try to match them with the grammar of the language they understood.
   

   • Here's where the real difference usually lies. See below for more.
   • Grammar understood by lexers: regular grammar (Chomsky's level 3).
   • Grammar understood by parsers: context-free grammar (Chomsky's level 2).

3. They attach semantics (meaning) to the language pieces they find.

   • Lexers attach meaning by classifying lexemes (strings of symbols from the input) as the particular tokens. E.g. All these lexemes: *, ==, <=, ^ will be classified as "operator" token by the C/C++ lexer.
   • Parsers attach meaning by classifying strings of tokens from the input (sentences) as the particular nonterminals and building the parse tree. E.g. all these token strings: [number][operator][number], [id][operator][id], [id][operator][number][operator][number] will be classified as "expression" nonterminal by the C/C++ parser.

4. They can attach some additional meaning (data) to the recognized elements.

   • When a lexer recognizes a character sequence constituting a proper number, it can convert it to its binary value and store with the "number" token.
   • Similarly, when a parser recognize an expression, it can compute its value and store with the "expression" node of the syntax tree.

5. They all produce on their output a proper sentences of the language they recognize.

   • Lexers produce tokens, which are sentences of the regular language they recognize. Each token can have an inner syntax (though level 3, not level 2), but that doesn't matter for the output data and for the one which reads them.
   • Parsers produce syntax trees, which are representations of sentences of the context-free language they recognize. Usually it's only one big tree for the whole document/source file, because the whole document/source file is a proper sentence for them. But there aren't any reasons why parser couldn't produce a series of syntax trees on its output. E.g. it could be a parser which recognizes SGML tags sticked into plain-text. So it'll tokenize the SGML document into a series of tokens: [TXT][TAG][TAG][TXT][TAG][TXT]....

As you can see, parsers and tokenizers have much in common. One parser can be a tokenizer for other parser, which reads its input tokens as symbols from its own alphabet (tokens are simply symbols of some alphabet) in the same way as sentences from one language can be alphabetic symbols of some other, higher-level language. For example, if * and - are the symbols of the alphabet M (as "Morse code symbols"), then you can build a parser which recognizes strings of these dots and lines as letters encoded in the Morse code. The sentences in the language "Morse Code" could be tokens for some other parser, for which these tokens are atomic symbols of its language (e.g. "English Words" language). And these "English Words" could be tokens (symbols of the alphabet) for some higher-level parser which understands "English Sentences" language. And all these languages differ only in the complexity of the grammar. Nothing more.

So what's all about these "Chomsky's grammar levels"? Well, Noam Chomsky classified grammars into four levels depending on their complexity:

• Level 3: Regular grammars

  They use regular expressions, that is, they can consist only of the symbols of alphabet (a,b), their concatenations (ab,aba,bbb etd.), or alternatives (e.g. a|b).
  They can be implemented as finite state automata (FSA), like NFA (Nondeterministic Finite Automaton) or better DFA (Deterministic Finite Automaton).
  Regular grammars can't handle with nested syntax, e.g. properly nested/matched parentheses (()()(()())), nested HTML/BBcode tags, nested blocks etc. It's because state automata to deal with it should have to have infinitely many states to handle infinitely many nesting levels.

• Level 2: Context-free grammars

  They can have nested, recursive, self-similar branches in their syntax trees, so they can handle with nested structures well.
  They can be implemented as state automaton with stack. This stack is used to represent the nesting level of the syntax. In practice, they're usually implemented as a top-down, recursive-descent parser which uses machine's procedure call stack to track the nesting level, and use recursively called procedures/functions for every non-terminal symbol in their syntax.
  But they can't handle with a context-sensitive syntax. E.g. when you have an expression x+3 and in one context this x could be a name of a variable, and in other context it could be a name of a function etc.

• Level 1: Context-sensitive grammars

• Level 0: Unrestricted grammars
  Also called recursively enumerable grammars.

Create a separate print stylesheet that hides all other elements except the content you want to print. Flag it using 'media="print" when you load it:

<link rel="stylesheet" type="text/css" media="print" href="print.css" />

This allows you to have a completely different stylesheet loaded for printouts.

If you want to force the browser's print dialog to appear for the page, you can do it like this on load using JQuery:

$(function() { window.print(); });

or triggered off of any other event you want such as a user clicking a button.

According to http://docs.python.org/dev/py3k/library/stdtypes.html#dictionary-view-objects , the keys(), values() and items() methods of a dict will return corresponding iterators whose orders correspond. However, I am unable to find a reference to the official documentation for python 2.x for the same thing.

So as far as I can tell, the answer is yes, but only in python 3.0+

I came across System.Runtime.InteropServices.COMException while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM Methods. I ran Visual Studio as Administrator and the exception was gone.

You could use np.where. If cond is a boolean array, and A and B are arrays, then

C = np.where(cond, A, B)

defines C to be equal to A where cond is True, and B where cond is False.

import numpy as np
import pandas as pd

a = [['10', '1.2', '4.2'], ['15', '70', '0.03'], ['8', '5', '0']]
df = pd.DataFrame(a, columns=['one', 'two', 'three'])

df['que'] = np.where((df['one'] >= df['two']) & (df['one'] <= df['three'])
                     , df['one'], np.nan)

yields

  one  two three  que
0  10  1.2   4.2   10
1  15   70  0.03  NaN
2   8    5     0  NaN

If you have more than one condition, then you could use np.select instead. For example, if you wish df['que'] to equal df['two'] when df['one'] < df['two'], then

conditions = [
    (df['one'] >= df['two']) & (df['one'] <= df['three']), 
    df['one'] < df['two']]

choices = [df['one'], df['two']]

df['que'] = np.select(conditions, choices, default=np.nan)

yields

  one  two three  que
0  10  1.2   4.2   10
1  15   70  0.03   70
2   8    5     0  NaN

If we can assume that df['one'] >= df['two'] when df['one'] < df['two'] is False, then the conditions and choices could be simplified to

conditions = [
    df['one'] < df['two'],
    df['one'] <= df['three']]

choices = [df['two'], df['one']]

(The assumption may not be true if df['one'] or df['two'] contain NaNs.)

Note that

a = [['10', '1.2', '4.2'], ['15', '70', '0.03'], ['8', '5', '0']]
df = pd.DataFrame(a, columns=['one', 'two', 'three'])

defines a DataFrame with string values. Since they look numeric, you might be better off converting those strings to floats:

df2 = df.astype(float)

This changes the results, however, since strings compare character-by-character, while floats are compared numerically.

In [61]: '10' <= '4.2'
Out[61]: True

In [62]: 10 <= 4.2
Out[62]: False

Judging from your example, shouldn't it be {% url myproject.login.views.login_view %} and end of story? (replace myproject with your actual project name)

Here's what I use. If it fails to pretty print the JSON it just returns the original string. Useful for printing HTTP responses that should contain JSON.

import (
    "encoding/json"
    "bytes"
)

func jsonPrettyPrint(in string) string {
    var out bytes.Buffer
    err := json.Indent(&out, []byte(in), "", "\t")
    if err != nil {
        return in
    }
    return out.String()
}

You can do that very easily if you can use Perl.

perl -ne 'if (/abc/) { $abc = 1; next }; print "Found in $ARGV\n" if ($abc && /efg/); }' yourfilename.txt

You can do that with a single regular expression too, but that involves taking the entire contents of the file into a single string, which might end up taking up too much memory with large files. For completeness, here is that method:

perl -e '@lines = <>; $content = join("", @lines); print "Found in $ARGV\n" if ($content =~ /abc.*efg/s);' yourfilename.txt

It might be interesting to some of you that in case of multiple default parameters:

void printValues(int x=10, int y=20, int z=30)
{
    std::cout << "Values: " << x << " " << y << " " << z << '\n';
}

Given the following function calls:

printValues(1, 2, 3);
printValues(1, 2);
printValues(1);
printValues();

The following output is produced:

Values: 1 2 3
Values: 1 2 30
Values: 1 20 30
Values: 10 20 30

To add class without JQuery just append yourClassName to your element className

document.documentElement.className += " yourClassName";

To remove class you can use replace() function

document.documentElement.className.replace(/(?:^|\s)yourClassName(?!\S)/,'');

Also as @DavidThomas mentioned you'd need to use the new RegExp() constructor if you want to pass class names dynamically to the replace function.

You have not specified the schema location of the context namespace, that is the reason for this specific error:

NOT mySQL, but for other people finding this question and using SQL, another way to resolve the greatest-n-per-group problem is using Cross Apply in MS SQL

WITH DocIds AS (SELECT DISTINCT id FROM docs)

SELECT d2.id, d2.rev, d2.content
FROM DocIds d1
CROSS APPLY (
  SELECT Top 1 * FROM docs d
  WHERE d.id = d1.id
  ORDER BY rev DESC
) d2

If you want to force Keras to use CPU

Way 1

import os
os.environ["CUDA_DEVICE_ORDER"] = "PCI_BUS_ID"   # see issue #152
os.environ["CUDA_VISIBLE_DEVICES"] = ""

before Keras / Tensorflow is imported.

Way 2

Run your script as

$ CUDA_VISIBLE_DEVICES="" ./your_keras_code.py

In my case I had to uninstall and reinstall the wireless adapter driver to be able to execute the command

With dates (and times) many things become simpler if you use >= start AND < end.

For example:

SELECT
  user_id
FROM
  user_logs
WHERE
      login_date >= '2014-02-01'
  AND login_date <  '2014-03-01'

In this case you still need to calculate the start date of the month you need, but that should be straight forward in any number of ways.

The end date is also simplified; just add exactly one month. No messing about with 28th, 30th, 31st, etc.

This structure also has the advantage of being able to maintain use of indexes.

Many people may suggest a form such as the following, but they do not use indexes:

WHERE
      DATEPART('year',  login_date) = 2014
  AND DATEPART('month', login_date) = 2

This involves calculating the conditions for every single row in the table (a scan) and not using index to find the range of rows that will match (a range-seek).

In this specific case it is Smarty, but it could also be Jinja2 templates. They usually also have a .tpl extension.

Depending on your use case, all the above solutions apply. This is how i usually do it however :

For server side code (e.g. a batch process) I usually load the entities and work with dynamic proxies. Usually in batch processes you need to load the data anyways at the time the service runs. I try to batch load the data instead of using the find method to save some time. Depending on the process I use optimistic or pessimistic concurrency control (I always use optimistic except for parallel execution scenarios where I need to lock some records with plain sql statements, this is rare though). Depending on the code and scenario the impact can be reduced to almost zero.

For client side scenarios, you have a few options

1. Use view models. The models should have a property UpdateStatus(unmodified-inserted-updated-deleted). It is the responsibility of the client to set the correct value to this column depending on the user actions (insert-update-delete). The server can either query the db for the original values or the client should send the original values to the server along with the changed rows. The server should attach the original values and use the UpdateStatus column for each row to decide how to handle the new values. In this scenario I always use optimistic concurrency. This will only do the insert - update - delete statements and not any selects, but it might need some clever code to walk the graph and update the entities (depends on your scenario - application). A mapper can help but does not handle the CRUD logic

2. Use a library like breeze.js that hides most of this complexity (as described in 1) and try to fit it to your use case.

Hope it helps

On the terminal, type:

$ sudo bash

Then write as many commands as you want. Type exit when you done.

If you need to automate it, create a script.sh file and run it:

$ sudo ./script.sh

There is also this:

select m from table where not regexp_like(m, '^[0-9]\d+$')

which selects the rows that contains characters from the column you want (which is m in the example but you can change).

Most of the combinations don't work properly in Oracle platforms but this does. Sharing for future reference.

Asking for commit before pull

• git stash
• git pull origin << branchname >>

If needed :

• git stash apply

This is one way to do it (in Python 3.x):

escaped = a_string.translate(str.maketrans({"-":  r"\-",
                                          "]":  r"\]",
                                          "\\": r"\\",
                                          "^":  r"\^",
                                          "$":  r"\$",
                                          "*":  r"\*",
                                          ".":  r"\."}))

For reference, for escaping strings to use in regex:

import re
escaped = re.escape(a_string)

It looks like you're trying to import some google code:

import com.google.common.base.Function;

And it's not finding it the class Function. Check to make sure all the required libraries are in your build path, and that you typed the package correctly.

Below I sum up Prateek Joshi's awesome explanation.

The theory:

• URI (uniform resource identifier) identifies a resource (text document, image file, etc)
• URL (uniform resource locator) is a subset of the URIs that include a network location
• URN (uniform resource name) is a subset of URIs that include a name within a given space, but no location

That is:

And for an example:

Also, if you haven't already, I suggest reading Roger Pate's answer.

This can happen when you are running IIS and you run the html page through it, then the Local file system will not be accessible.

To make your link work locally the run the calling html page directly from file browser not visual studio F5 or IIS simply click it to open from the file system, and make sure you are using the link like this:

<a href="file:///F:/VS_2015_WorkSpace/Projects/xyz/Intro.html">Intro</a>

Basically, you check if an object is an instance of a specific class. You normally use it, when you have a reference or parameter to an object that is of a super class or interface type and need to know whether the actual object has some other type (normally more concrete).

Example:

public void doSomething(Number param) {
  if( param instanceof Double) {
    System.out.println("param is a Double");
  }
  else if( param instanceof Integer) {
    System.out.println("param is an Integer");
  }

  if( param instanceof Comparable) {
    //subclasses of Number like Double etc. implement Comparable
    //other subclasses might not -> you could pass Number instances that don't implement that interface
    System.out.println("param is comparable"); 
  }
}

Note that if you have to use that operator very often it is generally a hint that your design has some flaws. So in a well designed application you should have to use that operator as little as possible (of course there are exceptions to that general rule).

<?php
session_start();
session_destroy();
header("Location: home.php");
?>

When you want to destroy a session completely, you need to do more then just

session_destroy();

First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:

<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>

The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.

Edit:

You need to remove the () from your exit code near the top of your script. it should just be

exit;

lapply(your_dataframe, class) gives you something like:

$tikr [1] "factor"

$Date [1] "Date"

$Open [1] "numeric"

$High [1] "numeric"

... etc.

This topic may be old, but here's a quick fix ul {list-style:outside none square;} or ul {list-style:outside none disc;} , etc...

then add left padding to list element

ul li{line-height: 1.4;padding-bottom: 6px;}

In this case u could use the org.apache.commons.lang3.StringUtilsand do

int nonEmptyStrings = s.filter(StringUtils::isNotEmpty).count();

A callback is a function that will be called when a process is done executing a specific task.

The usage of a callback is usually in asynchronous logic.

To create a callback in C#, you need to store a function address inside a variable. This is achieved using a delegate or the new lambda semantic Func or Action.

    public delegate void WorkCompletedCallBack(string result);

    public void DoWork(WorkCompletedCallBack callback)
    {
        callback("Hello world");
    }

    public void Test()
    {
        WorkCompletedCallBack callback = TestCallBack; // Notice that I am referencing a method without its parameter
        DoWork(callback);
    }

    public void TestCallBack(string result)
    {
        Console.WriteLine(result);
    }

In today C#, this could be done using lambda like:

    public void DoWork(Action<string> callback)
    {
        callback("Hello world");
    }

    public void Test()
    {
        DoWork((result) => Console.WriteLine(result));
    }

Readify made a very complete answer. Yet, I wanted to add the End statement, you can use:

Find the last used cell, before a blank in a Column:

Sub LastCellBeforeBlankInColumn()
Range("A1").End(xldown).Select
End Sub

Find the very last used cell in a Column:

Sub LastCellInColumn()
Range("A" & Rows.Count).End(xlup).Select
End Sub

Find the last cell, before a blank in a Row:

Sub LastCellBeforeBlankInRow()
Range("A1").End(xlToRight).Select
End Sub

Find the very last used cell in a Row:

Sub LastCellInRow()
Range("IV1").End(xlToLeft).Select
End Sub

See here for more information (and the explanation why xlCellTypeLastCell is not very reliable).

I know it really late for another answer but I just wanted to share what helped me at the end. It will also load resources/files from the absolute path of the file system (not only the classpath's).

public class ResourceLoader {

    public static URL getResource(String resource) {
        final List<ClassLoader> classLoaders = new ArrayList<ClassLoader>();
        classLoaders.add(Thread.currentThread().getContextClassLoader());
        classLoaders.add(ResourceLoader.class.getClassLoader());

        for (ClassLoader classLoader : classLoaders) {
            final URL url = getResourceWith(classLoader, resource);
            if (url != null) {
                return url;
            }
        }

        final URL systemResource = ClassLoader.getSystemResource(resource);
        if (systemResource != null) {
            return systemResource;
        } else {
            try {
                return new File(resource).toURI().toURL();
            } catch (MalformedURLException e) {
                return null;
            }
        }
    }

    private static URL getResourceWith(ClassLoader classLoader, String resource) {
        if (classLoader != null) {
            return classLoader.getResource(resource);
        }
        return null;
    }

}

I have just sent an email with gmail through Python. Try to use smtplib.SMTP_SSL to make the connection. Also, you may try to change the gmail domain and port.

So, you may get a chance with:

server = smtplib.SMTP_SSL('smtp.googlemail.com', 465)
server.login(gmail_user, password)
server.sendmail(gmail_user, TO, BODY)

As a plus, you could check the email builtin module. In this way, you can improve the readability of you your code and handle emails headers easily.

Example:

Heads up! This solution is CSS-only.

I recommend you take advantage of CSS3 to do that, by hidding the by-default input radio button with CSS3 rules:

.options input{
    margin:0;padding:0;
    -webkit-appearance:none;
       -moz-appearance:none;
            appearance:none;
}

I just make an example a few days ago.

There is no difference between both statements above. AS is just a more explicit way of mentioning the alias

If you have some changes on your workspace and you want to stash them into a new branch use this command:

git stash branch branchName

It will make:

1. a new branch
2. move changes to this branch
3. and remove latest stash (Like: git stash pop)

You could do this: <a href="">This page</a>

but I don't think it preserves GET and POST data.

The Installation Procedure is always the same, but the package-manager and package-name varies, depending which distribution, version and/or repository one uses. In general, the steps are:

a) at first, user privilege escalation is required, either obtained with the commands su or sudo.

b) then one can install the absent PHP module with a package manager.

c) after that, restarting the apache2 HTTP daemon is required to load the module.

d) at last, one can run php -m | grep imap to see if the PHP module is now available.

On Ubuntu the APT package php5-imap (or php-imap) can bei installed with apt-get:

apt-get install php5-imap
service apache2 restart

On Debian, the APT package php5-imap can be installed aptitude (or apt-get):

aptitude install php5-imap
apache2ctl graceful

On CentOS and Fedora the RPM package php-imap can be installed with yum (hint: the name of the package might be something alike php56w-imap or php71w-imap, when using Webtatic repo):

yum install php-imap
service httpd restart

On systemd systems, while using systemd units, the command to restart unit httpd.service is:

systemctl restart httpd.service

The solution stated above has the problem, that when the module was already referenced in:

/etc/php5/apache2/php.ini

It might throw a:

PHP Warning:  Module 'imap' already loaded in Unknown on line 0

That happens, because it is referenced in the default php.ini file (at least on Ubuntu 12.04) and a PHP module must at most be referenced once. Using INI snippets to load modules is suggested, while the the directory /etc/php5/conf.d/ (that path may also vary) is being scanned for INI files:

/etc/php5/conf.d/imap.ini

Ubuntu also features proprietary commands to manage PHP modules, to be executed before restarting the web-server:

php5enmod imap
php5dismod imap

Once the IMAP module is loaded into the server, the PHP IMAP Functions should then become available; best practice may be, to check if a module is even loaded, before attempting to utilize it.

Simplest: spread operators

var obj1 = {a: 1}
var obj2 = {b: 2}
var concat = { ...obj1, ...obj2 } // { a: 1, b: 2 }

SELECT PersonName, songName, status
FROM table
WHERE name IN ('Holly', 'Ryan')

If you are using parametrized Stored procedure:

1. Pass in comma separated string
2. Use special function to split comma separated string into table value variable
3. Use INNER JOIN ON t.PersonName = newTable.PersonName using a table variable which contains passed in names

you can use a formatstring

DateTime time = DateTime.Now;              
String format = "MMM ddd d HH:mm yyyy";     
Console.WriteLine(time.ToString(format));

Add the image to Your project by clicking File -> "Add Files to ...".

Then choose the image in ImageView properties (Utilities -> Attributes Inspector).

If one wants to have the conf\logging.properties read one must (see also here) dump this file into the Servers\Tomcat v7.0 Server at localhost-config\ folder and then add the lines :

-Djava.util.logging.config.file="${workspace_loc}\Servers\Tomcat v7.0 Server at localhost-config\logging.properties" -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

to the VM arguments of the launch configuration one is using.

This may have taken a restart or two (or not) but finally I saw in the console in bright red :

FINE: No TLD files were found in [file:/C:/Dropbox/eclipse_workspaces/javaEE/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/ted2012/WEB-INF/lib/logback-classic-1.0.7.jar]. Consider adding the JAR to the tomcat.util.scan.DefaultJarScanner.jarsToSkip or org.apache.catalina.startup.TldConfig.jarsToSkip property in CATALINA_BASE/conf/catalina.properties file. //etc

I still don't know when exactly this FINE warning appears - does not appear immediately on tomcat launch EDIT: from the comment by @Stephan: "The FINE warning appears each time any change is done in the JSP file".

Bonus: To make the warning go away add in catalina.properties :

# Additional JARs (over and above the default JARs listed above) to skip when
# scanning for TLDs. The list must be a comma separated list of JAR file names.
org.apache.catalina.startup.TldConfig.jarsToSkip=logback-classic-1.0.7.jar,\
joda-time-2.1.jar,joda-time-2.1-javadoc.jar,mysql-connector-java-5.1.24-bin.jar,\
logback-core-1.0.7.jar,javax.servlet.jsp.jstl-api-1.2.1.jar

Here is how you would add query string parameters using HttpClient 4.2 and later:

URIBuilder builder = new URIBuilder("http://example.com/");
builder.setParameter("parts", "all").setParameter("action", "finish");

HttpPost post = new HttpPost(builder.build());

The resulting URI would look like:

http://example.com/?parts=all&action=finish

We should always go for equals() method for comparison for two integers.Its the recommended practice.

If we compare two integers using == that would work for certain range of integer values (Integer from -128 to 127) due to JVM's internal optimisation.

Please see examples:

Case 1:

Integer a = 100; Integer b = 100;

if (a == b) {
    System.out.println("a and b are equal");
} else {
   System.out.println("a and b are not equal");
}

In above case JVM uses value of a and b from cached pool and return the same object instance(therefore memory address) of integer object and we get both are equal.Its an optimisation JVM does for certain range values.

Case 2: In this case, a and b are not equal because it does not come with the range from -128 to 127.

Integer a = 220; Integer b = 220;

if (a == b) {
    System.out.println("a and b are equal");
} else {
   System.out.println("a and b are not equal");
}

Proper way:

Integer a = 200;             
Integer b = 200;  
System.out.println("a == b? " + a.equals(b)); // true

I hope this helps.

Normally, I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6, I'd use JDK 6 because you would want your development environment to be as close as possible to the instructors. It would suck if you ran into an issue and having the thought in the back of your head that maybe it's because you're on JDK 7 that you're having the issue. Btw, I haven't touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you, I only code Android apps casually.

In jQuery documentation it says:

The matching text can appear directly within the selected element, in any of that element's descendants, or a combination

Therefore it is not enough that you use :contains() selector, you also need to check if the text you search for is the direct content of the element you are targeting for, something like that:

function findElementByText(text) {
    var jSpot = $("b:contains(" + text + ")")
                .filter(function() { return $(this).children().length === 0;})
                .parent();  // because you asked the parent of that element

    return jSpot;
}

Another solution is:

>>> "".join(list(hex(255))[2:])
'ff'

Probably an archaic answer, but functional.

docker ps --no-trunc will display the full command along with the other details of the running containers.

Here is my shot. I avoid swapping just by using the standard strcpy pattern:

char *string_reverse(char *dst, const char *src)
{
    if (src == NULL) return NULL;

    const char *src_start = src;
    char *dst_end = dst + strlen(src);
    *dst_end = '\0';

    while ((*--dst_end = *src_start++)) { ; }

    return dst;
}

and here a running example.

Thanks everybody for your help. Piecing together what I found here and elsewhere I came up with this:

The Code

command="php $INSTALL/indefero/scripts/gitcron.php"
job="0 0 * * 0 $command"
cat <(fgrep -i -v "$command" <(crontab -l)) <(echo "$job") | crontab -

I couldn't figure out how to eliminate the need for the two variables without repeating myself.

command is obviously the command I want to schedule. job takes $command and adds the scheduling data. I needed both variables separately in the line of code that does the work.

Details

1. Credit to duckyflip, I use this little redirect thingy (<(*command*)) to turn the output of crontab -l into input for the fgrep command.
2. fgrep then filters out any matches of $command (-v option), case-insensitive (-i option).
3. Again, the little redirect thingy (<(*command*)) is used to turn the result back into input for the cat command.
4. The cat command also receives echo "$job" (self explanatory), again, through use of the redirect thingy (<(*command*)).
5. So the filtered output from crontab -l and the simple echo "$job", combined, are piped ('|') over to crontab - to finally be written.
6. And they all lived happily ever after!

In a nutshell:

This line of code filters out any cron jobs that match the command, then writes out the remaining cron jobs with the new one, effectively acting like an "add" or "update" function. To use this, all you have to do is swap out the values for the command and job variables.

If the thing you want to compare is performance of file copying, then for the channel test you should do this instead:

final FileInputStream inputStream = new FileInputStream(src);
final FileOutputStream outputStream = new FileOutputStream(dest);
final FileChannel inChannel = inputStream.getChannel();
final FileChannel outChannel = outputStream.getChannel();
inChannel.transferTo(0, inChannel.size(), outChannel);
inChannel.close();
outChannel.close();
inputStream.close();
outputStream.close();

This won't be slower than buffering yourself from one channel to the other, and will potentially be massively faster. According to the Javadocs:

Many operating systems can transfer bytes directly from the filesystem cache to the target channel without actually copying them.

You can only use aggregates for comparison in the HAVING clause:

GROUP BY ...
  HAVING SUM(cash) > 500

The HAVING clause requires you to define a GROUP BY clause.

To get the first row where the sum of all the previous cash is greater than a certain value, use:

SELECT y.id, y.cash
  FROM (SELECT t.id,
               t.cash,
               (SELECT SUM(x.cash)
                  FROM TABLE x
                 WHERE x.id <= t.id) AS running_total
         FROM TABLE t
     ORDER BY t.id) y
 WHERE y.running_total > 500
ORDER BY y.id
   LIMIT 1

Because the aggregate function occurs in a subquery, the column alias for it can be referenced in the WHERE clause.

Try this... It works fine to compare Date properties between two DateTimes type:

PS. It is a stopgap solution and a really bad practice, should never be used when you know that the database can bring thousands of records...

query = query.ToList()
             .Where(x => x.FirstDate.Date == SecondDate.Date)
             .AsQueryable();

I think the main problems with the code you posted are:

• the first line matches on a host beginning with strictly sample.com, so www.sample.com doesn't match.

• the second line wants at least one character, followed by www.sample.com which also doesn't match (why did you escape the first w?)

• none of the included rules redirect to the url you specified in your goal (plus, sample is misspelled as samle, but that's irrelevant).

For reference, here's the code you currently have:

Options +FollowSymlinks
RewriteEngine on

RewriteCond %{HTTP_HOST} ^sample.com$
RewriteRule (.*) http://www.sample.com/$1 [R=301,L]

RewriteCond %{HTTP_HOST} ^(.+)\www.sample\.com$
RewriteRule ^/(.*)$ /samle/%1/$1 [L]

In my case eclipse is not showing parent class function on $this, so I perform below mention points and it starts works:-

I go to my /var/www/ folder and check for .metadata folder (Here check the .log file and it shows) Resource is out of sync with the file system: 1. Go to Eclipse --> Project --> Clean 2. Windows -- preferences --> General --> Workspace --> And set it to "Refresh Automatically"

After that boom - things gets start working :)

If you want to load variables from other files too then ado this :- Eclipse-->Windows-->Preferences-->Php-->Editor-->Content Assist --> and check "show variable from other files"

Then it will show element , variables and other functions also.

I would recommend that start using mysqli_() and stop using mysql_()

Check the following page: LINK

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include: mysqli_affected_rows() PDOStatement::rowCount()

Try and use mysqli_() Or PDO

C# code can be split between lines on pretty much any syntatic construct without a need for a '_' style construct.

For example

foo.
 Bar(
   42
 , "again");

Switch to the develop branch:

$ git checkout develop

Creates feature/foo branch of develop.

$ git checkout -b feature/foo develop

merge the changes to develop without a fast-forward

$ git checkout develop
$ git merge --no-ff myFeature

Now push changes to the server

$ git push origin develop
$ git push origin feature/foo

    python 3.2

    with open("d://test.txt") as f:
              k=(((i.split("\n"))[0].rstrip()).split() for i in f.readlines())
              d={}
              for i,_,v in k:
                      d.setdefault(i,[]).append(v)

The static keyword in C is used in a compiled file (.c as opposed to .h) so that the function exists only in that file.

Normally, when you create a function, the compiler generates cruft the linker can use to, well, link a function call to that function. If you use the static keyword, other functions within the same file can call this function (because it can be done without resorting to the linker), while the linker has no information letting other files access the function.

From number to currency string is easy through Number.prototype.toLocaleString. However the reverse seems to be a common problem. The thousands separator and decimal point may not be obtained in the JS standard.

In this particular question the thousands separator is a white space " " but in many cases it can be a period "." and decimal point can be a comma ",". Such as in 1 000 000,00 or 1.000.000,00. Then this is how i convert it into a proper floating point number.

var price = "1 000.000,99",
    value = +price.replace(/(\.|\s)|(\,)/g,(m,p1,p2) => p1 ? "" : ".");
console.log(value);

So the replacer callback takes "1.000.000,00" and converts it into "1000000.00". After that + in the front of the resulting string coerces it into a number.

This function is actually quite handy. For instance if you replace the p1 = "" part with p1 = "," in the callback function, an input of 1.000.000,00 would result 1,000,000.00

This is what worked for me

.parent {
padding-top: 1px;
margin-top: -1px;
}

.child {
margin-top:260px;
}

i did try this and its working in windows machine to run a sql file on a specific schema.

psql -h localhost -p 5432 -U username -d databasename -v schema=schemaname < e:\Table.sql

Simply SELECT @@system_time_zone;

Returns PST (or whatever is relevant to your system).

If you're trying to determine the session timezone you can use this query:
SELECT IF(@@session.time_zone = 'SYSTEM', @@system_time_zone, @@session.time_zone);

Which will return the session timezone if it differs from the system timezone.

Note that what you want is to know if stdin is connected to a terminal or not, not if it exists. It always exists but when you use the shell to pipe something into it or read a file, it is not connected to a terminal.

You can check that a file descriptor is connected to a terminal via the termios.h functions:

#include <termios.h>
#include <stdbool.h>

bool stdin_is_a_pipe(void)
{
    struct termios t;
    return (tcgetattr(STDIN_FILENO, &t) < 0);
}

This will try to fetch the terminal attributes of stdin. If it is not connected to a pipe, it is attached to a tty and the tcgetattr function call will succeed. In order to detect a pipe, we check for tcgetattr failure.

Perhaps you should look at adding a Settings File. (e.g. App.Settings) Creating this file will allow you to do the following:

string mysetting = App.Default.MySetting;
App.Default.MySetting = "my new setting";

This means you can edit and then change items, where the items are strongly typed, and best of all... you don't have to touch any xml before you deploy!

The result is a Application or User contextual setting.

Have a look in the "add new item" menu for the setting file.

The easiest way that I know of to get the number of entries in a table is with '#'. #tableName gets the number of entries as long as they are numbered:

tbl={
    [1]
    [2]
    [3]
    [4]
    [5]
}
print(#tbl)--prints the highest number in the table: 5

Sadly, if they are not numbered, it won't work.

Database access on main thread locking the UI is the error, like Dale said.

--EDIT 2--

Since many people may come across this answer... The best option nowadays, generally speaking, is Kotlin Coroutines. Room now supports it directly (currently in beta). https://kotlinlang.org/docs/reference/coroutines-overview.html https://developer.android.com/jetpack/androidx/releases/room#2.1.0-beta01

--EDIT 1--

For people wondering... You have other options. I recommend taking a look into the new ViewModel and LiveData components. LiveData works great with Room. https://developer.android.com/topic/libraries/architecture/livedata.html

Another option is the RxJava/RxAndroid. More powerful but more complex than LiveData. https://github.com/ReactiveX/RxJava

--Original answer--

Create a static nested class (to prevent memory leak) in your Activity extending AsyncTask.

private static class AgentAsyncTask extends AsyncTask<Void, Void, Integer> {

    //Prevent leak
    private WeakReference<Activity> weakActivity;
    private String email;
    private String phone;
    private String license;

    public AgentAsyncTask(Activity activity, String email, String phone, String license) {
        weakActivity = new WeakReference<>(activity);
        this.email = email;
        this.phone = phone;
        this.license = license;
    }

    @Override
    protected Integer doInBackground(Void... params) {
        AgentDao agentDao = MyApp.DatabaseSetup.getDatabase().agentDao();
        return agentDao.agentsCount(email, phone, license);
    }

    @Override
    protected void onPostExecute(Integer agentsCount) {
        Activity activity = weakActivity.get();
        if(activity == null) {
            return;
        }

        if (agentsCount > 0) {
            //2: If it already exists then prompt user
            Toast.makeText(activity, "Agent already exists!", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(activity, "Agent does not exist! Hurray :)", Toast.LENGTH_LONG).show();
            activity.onBackPressed();
        }
    }
}

Or you can create a final class on its own file.

Then execute it in the signUpAction(View view) method:

new AgentAsyncTask(this, email, phone, license).execute();

In some cases you might also want to hold a reference to the AgentAsyncTask in your activity so you can cancel it when the Activity is destroyed. But you would have to interrupt any transactions yourself.

Also, your question about the Google's test example... They state in that web page:

The recommended approach for testing your database implementation is writing a JUnit test that runs on an Android device. Because these tests don't require creating an activity, they should be faster to execute than your UI tests.

No Activity, no UI.

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

convert your inputs to ints:

width = int(input())
height = int(input())

Might be worthwhile using the CultureInfo to apply DateTime formatting throughout the website. Insteado f running around formatting whever you have to.

CultureInfo.CurrentUICulture.DateTimeFormat.SetAllDateTimePatterns( ...

or

CultureInfo.CurrentUICulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd"; 

Code should go somewhere in your Global.asax file

protected void Application_Start(){ ...

You can use a cursor and temp table approach so you aren't doing full table scan each time. What this would be doing is populating the temp table with all of your keywords, and then with each string in the @letters XML, it would remove any records from the temp table. At the end, you only have records in your temp table that have each of your desired strings in it.

declare @letters xml

SET @letters = '<letters>
            <letter>a</letter>
            <letter>b</letter>
        </letters>'

-- SELECTING LETTERS FROM THE XML
SELECT Letters.l.value('.', 'nvarchar(50)') AS letter
FROM @letters.nodes('/letters/letter') AS Letters(l)

-- CREATE A TEMP TABLE WE CAN DELETE FROM IF A RECORD DOESN'T HAVE THE LETTER
CREATE TABLE #TempResults (keywordID int not null, keyWord nvarchar(50) not null)
INSERT INTO #TempResults (keywordID, keyWord)
SELECT employeeID, firstName FROM Employee

-- CREATE A CURSOR, SO WE CAN LOOP THROUGH OUR LETTERS AND REMOVE KEYWORDS THAT DON'T MATCH
DECLARE Cursor_Letters CURSOR READ_ONLY
FOR 
    SELECT Letters.l.value('.', 'nvarchar(50)') AS letter
    FROM @letters.nodes('/letters/letter') AS Letters(l)

DECLARE @letter varchar(50)
OPEN Cursor_Letters

FETCH NEXT FROM Cursor_Letters INTO @letter
WHILE (@@fetch_status <> -1)
BEGIN
    IF (@@fetch_status <> -2)
    BEGIN
        DELETE FROM #TempResults 
        WHERE  keywordID NOT IN 
        (SELECT keywordID FROM #TempResults WHERE keyWord LIKE '%' + @letter + '%')
    END
    FETCH NEXT FROM Cursor_Letters INTO @letter
END

CLOSE Cursor_Letters
DEALLOCATE Cursor_Letters

SELECT * FROM #TempResults

DROP Table #TempResults
GO

Problem solved by downgrading to 2.3.5 from 2.3.8. (as well as infamous 'You are being redirected.' issue)

I use this for folders and files (don't know if it's optimal)

    if(Directory.GetFileSystemEntries(path).Length == 0)

The accepted answer gives you the number of GPUs but it also allocates all the memory on those GPUs. You can avoid this by creating a session with fixed lower memory before calling device_lib.list_local_devices() which may be unwanted for some applications.

I ended up using nvidia-smi to get the number of GPUs without allocating any memory on them.

import subprocess

n = str(subprocess.check_output(["nvidia-smi", "-L"])).count('UUID')

std::string s = "Sambuca";
QString q = s.c_str();

Warning: This won't work if the std::string contains \0s.

Try this:

$('#ddlCodes').change(function() {
  var option = this.options[this.selectedIndex];
  $('#txtEntry2').text($(option).text());
});

Use integers instead of strings.

make sure to cast your string to ints

price = int('1') * 9

The actual example code you posted will return 9 not 111111111

There is also a new option now in http://vimr.org/, which looks quite promising.

If you are using Spring Framework with application.yml and having trouble to make the test find the SQL file on the INIT property, you can use the classpath: notation.

For example, if you have a init.sql SQL file on the src/test/resources, just use:

url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM 'classpath:init.sql';DB_CLOSE_DELAY=-1;

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

another easy way using re will be

import re, clr

text = 'some string... this part will be removed.'

text= re.search(r'(\A.*)\.\.\..+',url,re.DOTALL|re.IGNORECASE).group(1)

// text = some string

lsof -i tcp:port_number - will list the process running on that port

kill -9 PID - will kill the process

in your case, it will be

lsof -i tcp:3000 from your terminal find the PID of process

kill -9 PID

I assume the reason you don't want it to close in Debug mode, is because you want to look at the values of variables etc. So it's probably best to just insert a break-point on the closing "}" of the main function. If you don't need to debug, then Ctrl-F5 is the best option.

1. window->preferences->java->Editor->Contest Assist
   
2. Enter in Auto activation triggers for java:
   abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._
   
3. Apply and Close
   

other method:
type initial letter then ctrl+spacebar for auto-complete options.

I want to share something that blocked us for a couple of days: the fileprovider code MUST be inserted between the application tags, not after it. It may be trivial, but it's never specified, and I thought that I could have helped someone! (thanks again to piolo94)
