Programs & Examples On #Background process

You need to save the PID of the background process at the time you start it:

foo &
FOO_PID=$!
# do other stuff
kill $FOO_PID

You cannot use job control, since that is an interactive feature and tied to a controlling terminal. A script will not necessarily have a terminal attached at all so job control will not necessarily be available.

Personally, I like the 'batch' command.

$ batch
> mycommand -x arg1 -y arg2 -z arg3
> ^D

This stuffs it in to the background, and then mails the results to you. It's a part of cron.

I believe the command you are looking for is start /b *command*

For unix, nohup represents 'no hangup', which is slightly different than a background job (which would be *command* &. I believe that the above command should be similar to a background job for windows.

$ disown node server.js &

It will remove command from active task list and send the command to background

I found a solution to implement this with the help of the Apple Developer Forums:

• Specify location background mode
• Create an NSTimer in the background with UIApplication:beginBackgroundTaskWithExpirationHandler:
• When n is smaller than UIApplication:backgroundTimeRemaining it will work just fine. When n is larger, the location manager should be enabled (and disabled) again before there is no time remaining to avoid the background task being killed.

This works because location is one of the three allowed types of background execution.

Note: I lost some time by testing this in the simulator where it doesn't work. However, it works fine on my phone.

May be the link will Help bcz u might have to implement the code in Appdelegate in app run in background method .. Also consult the developer.apple.com site for application class Here is link for runing app in background

templateUrl can be use as function with returning generated URL. We can manipulate url with passing argument which takes routeParams.

See the example.

.when('/:screenName/list',{
    templateUrl: function(params){
         return params.screenName +'/listUI'
    }
})

Hope this help.

The following commands resolved my issue:

npm config set proxy http://yourproxyurl.com:8080  (you need to enter your or your company proxy URL and 8080 should be replaced by your proxy port)

npm config set https-proxy http://yourproxyurl.com:8080

For FC22 server

cd /etc/httpd/conf edit httpd.conf [enter]

Change: Listen 80 to: Listen whatevernumber

Save the file

systemctl restart httpd.service [enter] if required, open whatevernumber in your router / firewall

There's no NotifyIcon for WPF.

A colleague of mine used this freely available library to good effect:

• http://www.hardcodet.net/wpf-notifyicon (blog post)
• https://bitbucket.org/hardcodet/notifyicon-wpf/src (source code)
• https://www.nuget.org/packages/Hardcodet.NotifyIcon.Wpf/ (NuGet package)
• http://visualstudiogallery.msdn.microsoft.com/aacbc77c-4ef6-456f-80b7-1f157c2909f7/

Run the script every 15 minutes of the hour. For example, you want to receive 15 minute stock price quotes, which are updated every 15 minutes.

while True:
    print("Update data:", datetime.now())
    sleep = 15 - datetime.now().minute % 15
    if sleep == 15:
        run_strategy()
        time.sleep(sleep * 60)
    else:
        time.sleep(sleep * 60)

From: jQuery text truncation (read more style)

Try this:

var title = "This is your title";

var shortText = jQuery.trim(title).substring(0, 10)
    .split(" ").slice(0, -1).join(" ") + "...";

• Tested here

And you can also use a plugin:

• jQuery Expander Plugin

As a extension of String

String.prototype.trimToLength = function(m) {
  return (this.length > m) 
    ? jQuery.trim(this).substring(0, m).split(" ").slice(0, -1).join(" ") + "..."
    : this;
};

Use as

"This is your title".trimToLength(10);

Maybe you should take a look here: http://en.wikipedia.org/wiki/Luhn_algorithm

Here is Java snippet which validates a credit card number which should be easy enough to convert to JavaScript:

  public static boolean isValidCC(String number) {

    final int[][] sumTable = {{0,1,2,3,4,5,6,7,8,9},{0,2,4,6,8,1,3,5,7,9}};
    int sum = 0, flip = 0;

    for (int i = number.length() - 1; i >= 0; i--) {
      sum += sumTable[flip++ & 0x1][Character.digit(number.charAt(i), 10)];
    }
    return sum % 10 == 0;
  }

I'm not sure that is the problem but what worked for me is calling mVideoView.start(); inside the mVideoView.setOnPreparedListener event callback.

For example:

Uri uriVideo = Uri.parse(<your link here>);

MediaController mediaController = new MediaController(mContext);
mediaController.setAnchorView(mVideoView);
mVideoView.setMediaController(mediaController);
mVideoView.setVideoURI(uriVideo);
mVideoView.requestFocus();

mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
{
     @Override
     public void onPrepared(MediaPlayer mp)
     {
          mVideoViewPeekItem.start();
     }
});

Was facing this issue, Solved by adding package-info in my package

and the following code in it:

@XmlSchema(
    namespace = "http://www.w3schools.com/xml/",
    elementFormDefault = XmlNsForm.QUALIFIED,
    xmlns = {
        @XmlNs(prefix="", namespaceURI="http://www.w3schools.com/xml/")
    }
)  
package com.gateway.ws.outbound.bean;

import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

You have to change the values in the CATALINA_OPTS option defined in the Tomcat Catalina start file. To increase the PermGen memory change the value of the MaxPermSize variable, otherwise change the value of the Xmx variable.

Linux & Mac OS: Open or create setenv.sh file placed in the "bin" directory. You have to apply the changes to this line:

export CATALINA_OPTS="$CATALINA_OPTS -server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"

Windows:

Open or create the setenv.bat file placed in the "bin" directory:

set CATALINA_OPTS=-server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m

This is probably the best solution you'll get. Simple and Easy. I learned it on udemy. Suppose you have two images having image id's id1 and id2 respectively and currently the image view is set as id1 and you want to change it to the other image everytime someone clicks in. So this is the basic code in MainActivity.java File

int clickNum=0;
public void click(View view){
clickNum++;
ImageView a=(ImageView)findViewById(R.id.id1);
ImageView b=(ImageView)findViewById(R.id.id2);
if(clickNum%2==1){
  a.animate().alpha(0f).setDuration(2000); //alpha controls the transpiracy
}
else if(clickNum%2==0){
  b.animate().alpha(0f).setDuration(2000); //alpha controls the transpiracy
}

}

I hope this will surely help

std::vector has a constructor that takes two iterators. You can use that:

std::string str = "hello";
std::vector<char> data(str.begin(), str.end());

If you already have a vector and want to add the characters at the end, you need a back inserter:

std::string str = "hello";
std::vector<char> data = /* ... */;
std::copy(str.begin(), str.end(), std::back_inserter(data));

Unfortunately SQL Developer doesn't fully honour the set echo off command that would (appear to) solve this in SQL*Plus.

The only workaround I've found for this is to save what you're doing as a script, e.g. test.sql with:

set echo off
spool c:\test.csv 
select /*csv*/ username, user_id, created from all_users;
spool off;

And then from SQL Developer, only have a call to that script:

@test.sql

And run that as a script (F5).

Saving as a script file shouldn't be much of a hardship anyway for anything other than an ad hoc query; and running that with @ instead of opening the script and running it directly is only a bit of a pain.

A bit of searching found the same solution on the SQL Developer forum, and the development team suggest it's intentional behaviour to mimic what SQL*Plus does; you need to run a script with @ there too in order to hide the query text.

This query is helpful for you. In this query, a column has data type varchar is arranged by good order.For example- In this column data are:- G1,G34,G10,G3. So, after running this query, you see the results: - G1,G10,G3,G34.

SELECT *,
       (CASE WHEN ISNUMERIC(column_name) = 1 THEN 0 ELSE 1 END) IsNum
FROM table_name 
ORDER BY IsNum, LEN(column_name), column_name;

You can also do

 Pushd "%~dp0"

Which also takes running from a unc path into consideration.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

You can set an enviroment variable to always have these options apply to all less'd file:

export LESS='-RS#3NM~g'

There's not need to do any of that. Only with

self.request.get('variable_name')

Notice that I'm not specifying the method (GET, POST, etc). This is well documented and this is an example

The fact that you use Django templates doesn't mean the handler is processed by Django as well

// Form A
public void loaddata()
{
    //do what you do in load data in order to update data in datagrid
}

then on Form B define:

// Form B
FormA obj = (FormA)Application.OpenForms["FormA"];

private void button1_Click(object sender, EventArgs e)
{
    obj.loaddata();
    datagridview1.Update();
    datagridview1.Refresh();
}

The code presented here doesn't show this discrepancy, but sometimes I get stuck when invoking dataframe in all lower case.

Switching to camel-case (pd.DataFrame()) cleans up the problem.

A good option is to use an API like Docverter. Docverter will allow you to convert HTML to PDF or DOCX using an API.

/ means the root of the current drive;

./ means the current directory;

../ means the parent of the current directory.

For Java:

Quantifiers documentation

X, exactly n times: X{n}
X, at least n times: X{n,}
X, at least n but not more than m times: X{n,m}

Easy and simple:

public static bool DirIsEmpty(string path) {
    int num = Directory.GetFiles(path).Length + Directory.GetDirectories(path).Length;
    return num == 0;
}

if anybody is experiencing is issue while updating to the latest react native, try updating your pod file with

  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
   end

It's a separate statement.

It's also not possible to insert into a table and select from it and build an index in the same statement either.

The BOL entry contains the information you need:

CLUSTERED | NONCLUSTERED
Indicate that a clustered or a nonclustered index is created for the PRIMARY KEY or UNIQUE constraint. PRIMARY KEY constraints default to CLUSTERED, and UNIQUE constraints default to NONCLUSTERED.

In a CREATE TABLE statement, CLUSTERED can be specified for only one constraint. If CLUSTERED is specified for a UNIQUE constraint and a PRIMARY KEY constraint is also specified, the PRIMARY KEY defaults to NONCLUSTERED.

You can create an index on a PK field, but not a non-clustered index on a non-pk non-unique-constrained field.

A NCL index is not relevant to the structure of the table, and is not a constraint on the data inside the table. It's a separate entity that supports the table but is not integral to it's functionality or design.

That's why it's a separate statement. The NCL index is irrelevant to the table from a design perspective (query optimization notwithstanding).

You can use LABEL element ex.

<div>_x000D_
    <label for="browse">Click Me</label>_x000D_
    <input type="file" id="browse" name="browse" style="display: none">//_x000D_
</div>

This will trigger the input file

I had the same issue. This is what worked for me.

There are 2 php.ini files:

• C:\wamp\bin\apache\apache2.4.9\bin
• C:\wamp\bin\php\php5.5.12

NOTE: This is using my version of PHP and Apache, change to what yours are.

The php.ini file located in the both folders is what you need to update, the extentions:

• extension=php_pdo_pgsql.dll
• extension=php_pgsql.dll

These are what you need to uncomment (remove the ; symbol).

Restart both Wamp and the Command Prompt.

Hopefully it will work for you :).

When would you use private and when would you use protected?

Private Inheritance can be thought of Implemented in terms of relationship rather than a IS-A relationship. Simply put, the external interface of the inheriting class has no (visible) relationship to the inherited class, It uses the private inheritance only to implement a similar functionality which the Base class provides.

Unlike, Private Inheritance, Protected inheritance is a restricted form of Inheritance,wherein the deriving class IS-A kind of the Base class and it wants to restrict the access of the derived members only to the derived class.

Here's an old-fashioned unix trick for removing the last 3 characters from a line that makes no use of sed OR awk...

> echo 987654321 | rev | cut -c 4- | rev

987654

Unlike the earlier example using 'cut', this does not require knowledge of the line length.

The approach that I am giving is the fastest pagination that SQL server can achieve. I have tested this on 5 million records. This approach is far better than "OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY" provided by SQL Server.

-- The below given code computes the page numbers and the max row of previous page
-- Replace <<>> with the correct table data.
-- Eg. <<IdentityColumn of Table>> can be EmployeeId and <<Table>> will be dbo.Employees

DECLARE @PageNumber int=1; --1st/2nd/nth page. In stored proc take this as input param.
DECLARE @NoOfRecordsPerPage int=1000;

 DECLARE @PageDetails TABLE
       (
        <<IdentityColumn of Table>> int,
        rownum int,
        [PageNumber] int
       )           
       INSERT INTO @PageDetails values(0, 0, 0)
       ;WITH CTE AS
       (
       SELECT <<IdentityColumn of Table>>, ROW_NUMBER() OVER(ORDER BY <<IdentityColumn of Table>>) rownum FROM <<Table>>
       )
       Insert into @PageDetails 
       SELECT <<IdentityColumn of Table>>, CTE.rownum, ROW_NUMBER() OVER (ORDER BY rownum) as [PageNumber] FROM CTE WHERE CTE.rownum%@NoOfRecordsPerPage=0


--SELECT * FROM @PageDetails 

-- Actual pagination
SELECT TOP (@NoOfRecordsPerPage)
FROM <<Table>> AS <<Table>>
WHERE <<IdentityColumn of Table>> > (SELECT <<IdentityColumn of Table>> FROM 
@PageDetails WHERE PageNumber=@PageNumber)
ORDER BY <<Identity Column of Table>>

Another thing to know about, in some cases, you have to use the Delegates/Events when you need a low level of coupling !

If you want to use a component in several place in application, you need to make a component with low level of coupling and the specific unconcerned LOGIC must be delegated OUTSIDE of your component ! This ensures that you have a decoupled system and a cleaner code.

In SOLID principle this is the "D", (Dependency inversion principle).

Also known as "IoC", Inversion of control.

You can make "IoC" with Events, Delegates and DI (Dependency Injection).

It's easy to access a method in a child class. But more difficult to access a method in a parent class from child. You have to pass the parent reference to the child ! (or use DI with Interface)

Delegates/Events allows us to communicate from the child to the parent without reference !

In this diagram above, I do not use Delegate/Event and the parent component B has to have a reference of the parent component A to execute the unconcerned business logic in method of A. (high level of coupling)

With this approach, I would have to put all the references of all components that use component B ! :(

In this diagram above, I use Delegate/Event and the component B doesn't have to known A. (low level of coupling)

And you can use your component B anywhere in your application !

The short version of the most voted answer has problems with TB values.

I adjusted it appropriately to handle also tb values and still without a loop and also added a little error checking for negative values. Here's my solution:

static readonly string[] SizeSuffixes = { "bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB" };
static string SizeSuffix(long value, int decimalPlaces = 0)
{
    if (value < 0)
    {
        throw new ArgumentException("Bytes should not be negative", "value");
    }
    var mag = (int)Math.Max(0, Math.Log(value, 1024));
    var adjustedSize = Math.Round(value / Math.Pow(1024, mag), decimalPlaces);
    return String.Format("{0} {1}", adjustedSize, SizeSuffixes[mag]);
}

strncpy fills the destination up with '\0' for the size of source, eventhough the size of the destination is smaller....

manpage:

If the length of src is less than n, strncpy() pads the remainder of dest with null bytes.

and not only the remainder...also after this until n characters is reached. And thus you get an overflow... (see the man page implementation)

This piece of code will help you better solve your problem, as we cannot specify width directly to the RaisedButton, we can specify the width to it's child

double width = MediaQuery.of(context).size.width;
var maxWidthChild = SizedBox(
            width: width,
            child: Text(
              StringConfig.acceptButton,
              textAlign: TextAlign.center,
            ));

RaisedButton(
        child: maxWidthChild,
        onPressed: (){},
        color: Colors.white,
    );

Non greedy search in vim is done using {-} operator. Like this:

%s/style=".\{-}"//g

just try:

:help non-greedy

Button button1=(Button)findViewById(R.id.btnB1);
button1.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
MediaPlayer mp1 = MediaPlayer.create(this, R.raw.b1);
mp1.start();
}
});

Try this i think it will work

I was almost using the same technology as you did, however I was using my app to connect an Exchange Server via Office 365 platform on WinForms. I too had the same issue as you did, but was able to accomplish by using code which has slight modification of what others have given above.

SmtpClient client = new SmtpClient(exchangeServer, 587);
client.Credentials = new System.Net.NetworkCredential(username, password);
client.EnableSsl = true;
client.Send(msg);

I had to use the Port 587, which is of course the default port over TSL and the did the authentication.

"I need to install it to the folder of my C program." Why?

Include usb.h:

Improved version of what Ustaman Sangat did

static inline uint64_t
log2(uint64_t n)
{
    uint64_t val;
    for (val = 0; n > 1; val++, n >>= 1);

    return val;
}

You may as well use for x in values rather than for x in values[:]; the latter makes an unnecessary copy. Also, of course that code checks for a length of 2 rather than of 3...

The code only prints one item per value of x - and x is iterating over the elements of values, which are the sublists. So it will only print each sublist once.

Maybe this seems ugly, but why not just run cat and let it wait for input forever?

A bit late, but to anyone who is wondering why they are getting the "Warning: Cannot use a scalar value as an array" message;

the reason is because somewhere you have first declared your variable with a normal integer or string and then later you are trying to turn it into an array.

hope that helps

In the your first journey in spring boot project I recommend you to start with Spring Starter Try this link here.

It will auto generate the project structure for you like this.application.perperties it will be under /resources.

application.properties important change,

server.port = Your PORT(XXXX) by default=8080
server.servlet.context-path=/api (SpringBoot version 2.x.)
server.contextPath-path=/api (SpringBoot version < 2.x.)

Any way you can use application.yml in case you don't want to make redundancy properties setting.

Example
application.yml

server:
   port: 8080 
   contextPath: /api

application.properties

server.port = 8080
server.contextPath = /api

For me git branch --merged doesn't show branches that were merged via GitHub PR. I'm not sure of the reasons, but I use the following line to delete all local branches that do not have remote tracking branch:

diff <(git branch --format "%(refname:short)") <(git branch -r | grep -v HEAD | cut -d/ -f2-) | grep '<' | cut -c 3- | xargs git branch -D

Explanation:

• git branch --format "%(refname:short)" gives a list of local branches
• git branch -r | grep -v HEAD | cut -d/ -f2- gives a list of remote branches, filtering out HEAD
• diff <(...) <(...) gives a diff of output of two commands inside parentheses
• grep '<' filters branches that exist in first list, but not in the second
• cut -c 3- gives line starting from 3rd character, thus removing prefix <
• xargs git branch -D executes git branch -D against each branch name

Alternatively, you can avoid grep -v '<' like this:

diff --old-line-format="%L" --new-line-format="" --unchanged-line-format="" <(git branch --format "%(refname:short)") <(git branch -r | grep -v HEAD | cut -d/ -f2-) | xargs git branch -D

If the adb connection is ever lost:

Make sure that your host is still connected to the same Wi-Fi network your Android device is. Reconnect by executing the "adb connect IP" step. (IP is obviously different when you change location.) Or if that doesn't work, reset your adb host: adb kill-server and then start over from the beginning.

Encapsulate your writer to provide char replacement, like this:

public class WindowsFileWriter extends Writer {

    private Writer writer;

    public WindowsFileWriter(File file) throws IOException {
        try {
            writer = new OutputStreamWriter(new FileOutputStream(file), "ISO-8859-15");
        } catch (UnsupportedEncodingException e) {
            writer = new FileWriter(logfile);
        }
    }

    @Override
    public void write(char[] cbuf, int off, int len) throws IOException {
        writer.write(new String(cbuf, off, len).replace("\n", "\r\n"));
    }

    @Override
    public void flush() throws IOException {
        writer.flush();
    }

    @Override
    public void close() throws IOException {
        writer.close();
    }

}

Don't split on commas -- it won't work for most CSV files, and this question has wayyyy too many views for the asker's kind of input data to apply to everyone. Parsing CSV is kind of scary since there's no truly official standard, and lots of delimited text writers don't consider edge cases.

This question is old, but I believe there's a better solution now that Papa Parse is available. It's a library I wrote, with help from contributors, that parses CSV text or files. It's the only JS library I know of that supports files gigabytes in size. It also handles malformed input gracefully.

1 GB file parsed in 1 minute:

(Update: With Papa Parse 4, the same file took only about 30 seconds in Firefox. Papa Parse 4 is now the fastest known CSV parser for the browser.)

Parsing text is very easy:

var data = Papa.parse(csvString);

Parsing files is also easy:

Papa.parse(file, {
    complete: function(results) {
        console.log(results);
    }
});

Streaming files is similar (here's an example that streams a remote file):

Papa.parse("http://example.com/bigfoo.csv", {
    download: true,
    step: function(row) {
        console.log("Row:", row.data);
    },
    complete: function() {
        console.log("All done!");
    }
});

If your web page locks up during parsing, Papa can use web workers to keep your web site reactive.

Papa can auto-detect delimiters and match values up with header columns, if a header row is present. It can also turn numeric values into actual number types. It appropriately parses line breaks and quotes and other weird situations, and even handles malformed input as robustly as possible. I've drawn on inspiration from existing libraries to make Papa, so props to other JS implementations.

I selected the cells I wanted locked out in sheet1 and place the suggested code in the open_workbook() function and worked like a charm.

ThisWorkbook.Worksheets("Sheet1").Protect Password:="Password", _
UserInterfaceOnly:=True

Actually, it's because CSS defines 100% relative to the entire width of the container, including its margins, borders, and padding; that means that the space avail. to its contents is some amount smaller than 100%, unless the container has no margins, borders, or padding.

This is counter-intuitive and widely regarded by many to be a mistake that we are now stuck with. It effectively means that % dimensions are no good for anything other than a top level container, and even then, only if it has no margins, borders or padding.

Note that the text field's margins, borders, and padding are included in the CSS size specified for it - it's the container's which throw things off.

I have tolerably worked around it by using 98%, but that is a less than perfect solution, since the input fields tend to fall further short as the container gets larger.

EDIT: I came across this similar question - I've never tried the answer given, and I don't know for sure if it applies to your problem, but it seems like it will.

How about using ES6 template literals?

var a = "cat";
var b = "fat";
console.log(`my ${a} is ${b}`); //notice back-ticked string

More about template literals...

IMHO people who use short tags often forget to escape whatever they're echoing. It would be nice to have a template engine that escapes by default. I believe Rob A wrote a quick hack to escape short tags in Zend Frameworks apps. If you like short tags because it makes PHP easier to read. Then might Smarty be a better option?

{$myString|escape}

to me that looks better than

<?= htmlspecialchars($myString) ?> 

$("#myform input:checkbox").change(function() {
    $("#myform input:checkbox").attr("checked", false);
    $(this).attr("checked", true);
});

This should work for any number of checkboxes in the form. If you have others that aren't part of the group, set up the selectors the applicable inputs.

Don't get confused with the concepts of Angular and RxJS

We have pipes concept in Angular and pipe() function in RxJS.

1) Pipes in Angular: A pipe takes in data as input and transforms it to the desired output
https://angular.io/guide/pipes

2) pipe() function in RxJS: You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.
https://angular.io/guide/rx-library (search for pipes in this URL, you can find the same)

So according to your question, you are referring pipe() function in RxJS

I think that this code is going to help:

JS:

$('#foo').ready(function () {
    $('#loadingMessage').css('display', 'none');
});
$('#foo').load(function () {
    $('#loadingMessage').css('display', 'none');
});

HTML:

<iframe src="http://google.com/" id="foo"></iframe>
<div id="loadingMessage">Loading...</div>

CSS:

#loadingMessage {
    width: 100%;
    height: 100%;
    z-index: 1000;
    background: #ccc;
    top: 0px;
    left: 0px;
    position: absolute;
}

Just create and save a page token in global variable with window.nextPageToken. Send this to API server everytime you make a request and have it return the next one with response and you can easily keep track of last token. The below is an example how you can move forward and backward from search results. The key is the offset you send to API based on the nextPageToken that you have saved:

function getPrev() {
  var offset = Number(window.nextPageToken) - limit * 2;
  if (offset < 0) {
    offset = 0;
  }
  window.nextPageToken = offset;
  if (canSubmit(searchForm, offset)) {
    searchForm.submit();
  }
}

function getNext() {
  var offset = Number(window.nextPageToken);
  window.nextPageToken = offset;
  if (canSubmit(searchForm, offset)) {
    searchForm.submit();
  }
}

If someone uses jquery, he can do it like this :

var click_count = 0;
$( "canvas" ).bind( "click", function( event ) {
    //do whatever you want
    click_count++;
    if ( click_count == 50 ) {
        //remove the event
        $( this ).unbind( event );
    }
});

Hope that it can help someone. Note that the answer given by @user113716 work nicely :)

you need to add the view controller that will present the new controller as a child of the parent view controller.

Let's say you have yourMainViewController, then you add a new controller called controllerA, and then you want to present a new controller called controllerB from controllerA

you have to write something like this:

[self addChildViewController:controllerA]; //self is yourMainViewController
[self.view addsubView:controllerA.view]; 

and within controllerA you can present the new controller without warnings

[self presentViewController:controllerB animated:YES completion:nil]; //self is controllerA

For Unit Tests, the System variable is not instantiated yet when I do "mvn clean install" because there is no server running the application. So in order to set the System properties, I need to do it in pom.xml. Like so:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <configuration>
        <systemPropertyVariables>
            <propertyName>propertyValue</propertyName>
            <MY_ENV_VAR>newValue</MY_ENV_VAR>
            <ENV_TARGET>olqa</ENV_TARGET>
            <buildDirectory>${project.build.directory}</buildDirectory>
        </systemPropertyVariables>
    </configuration>
</plugin>

You can use self.data in the clean_email method to access the POST data before validation. It should contain a key called newsletter_sub or newsletter_unsub depending on which button was pressed.

# in the context of a django.forms form

def clean(self):
    if 'newsletter_sub' in self.data:
        # do subscribe
    elif 'newsletter_unsub' in self.data:
        # do unsubscribe

Add this code into the css file:

input {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}

This will help.

The std::mismatch method can serve this purpose when used to backwards iterate from the end of both strings:

const string sNoFruit = "ThisOneEndsOnNothingMuchFruitLike";
const string sOrange = "ThisOneEndsOnOrange";

const string sPattern = "Orange";

assert( mismatch( sPattern.rbegin(), sPattern.rend(), sNoFruit.rbegin() )
          .first != sPattern.rend() );

assert( mismatch( sPattern.rbegin(), sPattern.rend(), sOrange.rbegin() )
          .first == sPattern.rend() );

I had the problem with npm throwing this error.

So basically whenever error was thrown i either used manual install
from git or waited and installed specified version like:

npm install resolve@^1.1.6

when running alone:

npm install resolve

didn't worked.

I updated node.js from 7 to 8 and npm install goes smoothly.

I think that maybe the version 7 caused this problem since @luschn downgraded to 6 so he didn't use 7 too.

Maybe the registry itself is returning errors without showing problems on their status pages because after some time i could install this one breaking package and then proceed with npm install to install the rest.

if the string is mutable, then you can transform it in place using this form:

[string replaceOccurrencesOfString:@" "
                        withString:@""
                           options:0
                             range:NSMakeRange(0, string.length)];

this is also useful if you would like the result to be a mutable instance of an input string:

NSMutableString * string = [concreteString mutableCopy];
[string replaceOccurrencesOfString:@" "
                        withString:@""
                           options:0
                             range:NSMakeRange(0, string.length)];

No you can't, as Mladen Prajdic said. Think of a view as a "static filter" on a table or a combination of tables. For example: a view may combine tables Order and Customer so you get a new "table" of rows from Order along with new columns containing the customer's name and the customer number (combination of tables). Or you might create a view that selects only unprocessed orders from the Order table (static filter).

You'd then select from the view like you would select from any other "normal" table - all "non-static" filtering must be done outside the view (like "Get all the orders for customers called Miller" or "Get unprocessed orders that came in on Dec 24th").

This problem often happens when a django project deploys using Apache. Because Apache sets environment variable LANG=C in /etc/sysconfig/httpd. Just open the file and comment (or change to your flavior) this setting. Or use the lang option of the WSGIDaemonProcess command, in this case you will be able to set different LANG environment variable to different virtualhosts.

See the most recent stash:

git stash show -p

See an arbitrary stash:

git stash show -p stash@{1}

From the git stash manpages:

By default, the command shows the diffstat, but it will accept any format known to git diff (e.g., git stash show -p stash@{1} to view the second most recent stash in patch form).

Visual Studio 2017 Debug symbol "speed-up" options, assuming you haven't gone crazy on option-customization already:

1. At Tools -> Options -> Debugging -> Symbols
   a. Enable the "Microsoft Symbol Server" option
   b. Click "Empty Symbol Cache"
   c. Set your symbol cache to an easy to find spot, like C:\dbg_symbols or %USERPROFILE%\dbg_symbols
2. After re-running Debug, let it load all the symbols once, from start-to-end, or as much as reasonably possible.

1A and 2 are the most important steps. 1B and 1C are just helpful changes to help you keep track of your symbols.

After your app has loaded all the symbols at least once and debugging didn't prematurely terminate, those symbols should be quickly loaded the next time debug runs.

I've noticed that if I cancel a debug-run, I have to reload those symbols, as I'm guessing they're "cleaned" up if newly introduced and suddenly cancelled. I understand the core rationale for that kind of flow, but in this case it seems poorly thought out.

Usage of javascript:void(0) means that the author of the HTML is misusing the anchor element in place of the button element.

Anchor tags are often abused with the onclick event to create pseudo-buttons by setting href to "#" or "javascript:void(0)" to prevent the page from refreshing. These values cause unexpected behavior when copying/dragging links, opening links in a new tabs/windows, bookmarking, and when JavaScript is still downloading, errors out, or is disabled. This also conveys incorrect semantics to assistive technologies (e.g., screen readers). In these cases, it is recommended to use a <button> instead. In general you should only use an anchor for navigation using a proper URL.

try getHibernateTemplate().saveOrUpdate()

For folks searching for solution to set spacing between N divs, here is another approach using pseudo selectors:

div:not(:last-child) {
  margin-right: 40px;
}

You can also combine child pseudo selectors:

div:not(:first-child):not(:last-child) {
  margin-left: 20px;
  margin-right: 20px;
}

Isn't this exactly what squashing a rebase does? Just squash everything except the last commit and then (force) push it.

I have Windows 10 64 bit, this worked for me, This solution can work for both (Anaconda/MiniConda) distributions.

1. First of all try to uninstall anaconda/miniconda which is causing problem.
2. After that delete '.anaconda' and '.conda' folders from 'C:\Users\'

3. If you have any antivirus software installed then try to exclude all the folders,subfolders inside 'C:\ProgramData\Anaconda3\' from

   • Behaviour detection.
   • Virus detection.
   • DNA scan.
   • Suspicious files scan.
   • Any other virus protection mode.

   *(Note: 'C:\ProgramData\Anaconda3' this folder is default installation folder, you can change it just replace your excluded path at installation destination prompt while installing Anaconda)*

4. Now install Anaconda with admin privileges.
   • Set the installation path as 'C:\ProgramData\Anaconda3' or you can specify your custom path just remember it should not contain any white space and it should be excluded from virus detection.
   • At Advanced Installation Options you can check "Add Anaconda to my PATH environment variable(optional)" and "Register Anaconda as my default Python 3.6"
   • Install it with further default settings. Click on finish after done.
   • Restart your computer.

Now open Command prompt or Anaconda prompt and check installation using following command

conda list

If you get any package list then the anaconda/miniconda is successfully installed.

The indexOf() methods are all case-sensitive. You can make them (roughly, in a broken way, but working for plenty of cases) case-insensitive by converting your strings to upper/lower case beforehand:

s1 = s1.toLowerCase(Locale.US);
s2 = s2.toLowerCase(Locale.US);
s1.indexOf(s2);

You could just loop the rows and read the same cell from each row (doesn't this comprise a column?).

The most obvious solutions are already listed. Depending on where the query is sat (i.e. in application code) you can't always use IF statements and the inline CASE statements can get painful where lots of columns become conditional. Assuming Col1 + Col3 + Col7 are the same type, and likewise Col2, Col4 + Col8 you can do this:

SELECT Col1, Col2 FROM tbl WHERE @Var LIKE 'xyz'
UNION ALL
SELECT Col3, Col4 FROM tbl WHERE @Var LIKE 'zyx'
UNION ALL
SELECT Col7, Col8 FROM tbl WHERE @Var NOT LIKE 'xyz' AND @Var NOT LIKE 'zyx'

As this is a single command there are several performance benefits with regard to plan caching. Also the Query Optimiser will quickly eliminate those statements where @Var doesn't match the appropriate value without touching the storage engine.

You can escape the quotes with a backslash:

"I asked my son's teacher, \"How is my son doing now?\""

In this link explain about @model, see a excerpt:

@model (lowercase "m") is a reserved keyword in Razor views to declare the model type at the top of your view. You have put the namespace too, e.g.: @model MyNamespace.Models.MyModel

Later in the file, you can reference the attribute you want with @Model.Attribute (uppercase "M").

Nowadays, in Python 2.7 and up, you can use a dict comprehension:

{k: v for k, v in points.iteritems() if v[0] < 5 and v[1] < 5}

And in Python 3:

{k: v for k, v in points.items() if v[0] < 5 and v[1] < 5}

We all know that PHP save errors in php_errors.log file.

But, that file contains a lot of data.

If we want to log our application data, we need to save it to a custom location.

We can use two parameters in the error_log function to achieve this.

http://php.net/manual/en/function.error-log.php

We can do it using:

error_log(print_r($v, TRUE), 3, '/var/tmp/errors.log');

Where,

print_r($v, TRUE) : logs $v (array/string/object) to log file. 3: Put log message to custom log file specified in the third parameter.

'/var/tmp/errors.log': Custom log file (This path is for Linux, we can specify other depending upon OS).

OR, you can use file_put_contents()

file_put_contents('/var/tmp/e.log', print_r($v, true), FILE_APPEND);

Where:

'/var/tmp/errors.log': Custom log file (This path is for Linux, we can specify other depending upon OS). print_r($v, TRUE) : logs $v (array/string/object) to log file. FILE_APPEND: Constant parameter specifying whether to append to the file if it exists, if file does not exist, new file will be created.

i have a solution who work here to check if internet connection exist :

$.ajax({
    url: "http://www.google.com",
    context: document.body,
    error: function(jqXHR, exception) {
        alert('Offline')
    },
    success: function() {
        alert('Online')
    }
})

You got a bunch of good answers, so I'll just throw out a suggestion. If you are going to be working on this project for more than 2 days, download eclipse or netbeans and build your project in there.

If you are not normally a java programmer, then the help it will give you will be invaluable.

It's not worth the 1/2 hour download/install if you are only spending 2 hours on it.

Both have hotkeys/menu items to "Fix imports", with this you should never have to worry about imports again.

I found this presentation to be very helpfull.

How I Distribute Python applications on Windows - py2exe & InnoSetup

From the site:

There are many deployment options for Python code. I'll share what has worked well for me on Windows, packaging command line tools and services using py2exe and InnoSetup. I'll demonstrate a simple build script which creates windows binaries and an InnoSetup installer in one step. In addition, I'll go over common errors which come up when using py2exe and hints on troubleshooting them. This is a short talk, so there will be a follow-up Open Space session to share experience and help each other solve distribution problems.

Thanks a bundle, guys. You are great.

I used Chuff's answer and modified it a little to do what I wanted.

I have 2 worksheets in the same workbook.

On 1st worksheet I have a list of SMS in 3 columns: phone number, date & time, message

Then I inserted a new blank column next to the phone number

On worksheet 2 I have two columns: phone number, name of person

Used the formula to check the cell on the left, and match against the range in worksheet 2, pick the name corresponding to the number and input it into the blank cell in worksheet 1.

Then just copy the formula down the whole column until last sms It worked beautifully.

=VLOOKUP(A3,Sheet2!$A$1:$B$31,2,0)

Underscore-java library contains methods push(values), pop(), shift() and unshift(values).

Code example:

import com.github.underscore.U:

List<String> strings = Arrays.asList("one", "two", " three");
List<String> newStrings = U.push(strings, "four", "five");
// ["one", " two", "three", " four", "five"]
String newPopString = U.pop(strings).fst();
// " three"
String newShiftString = U.shift(strings).fst();
// "one"
List<String> newUnshiftStrings = U.unshift(strings, "four", "five");
// ["four", " five", "one", " two", "three"]

you should not use Nested List in List.

List<List<T>> 

is not legal, even if T were a defined type.

https://msdn.microsoft.com/en-us/library/ms182144.aspx

I do it using the following :-

package main

import (
    "fmt"
    "strings"
)

func main (){
    concatenation:= strings.Join([]string{"a","b","c"},"") //where second parameter is a separator. 
    fmt.Println(concatenation) //abc
}

There is a JSONObject constructor to turn a String into a JSONObject:

http://developer.android.com/reference/org/json/JSONObject.html#JSONObject(java.lang.String)

I doubt css understands left by itself. You need to use it specifying position. You are using .css() correctly

position: relative/absolute/whatever;
left: 900px;

heres a fiddle of it working

http://jsfiddle.net/gFLZe/

and without the position here's what you get

http://jsfiddle.net/gkkm5/

Change your if statement to be like this - with quotes around -900px

var n = $("items").css("left");

if(n == '-900px'){
    $(".items span").fadeOut("slow");

Take a look at the Maven dependency plugin, specifically, the dependency:copy-dependencies goal. Take a look at the example under the heading The dependency:copy-dependencies mojo. Set the outputDirectory configuration property to ${basedir}/target/lib (I believe, you'll have to test).

Hope this helps.

The problem with jeet's answer is that you load all bytes of the image into a byte array, which will likely crash the app in low-end devices. Instead, I would first write the image to a file and read it using Apache's Base64InputStream class. Then you can create the Base64 string directly from the InputStream of that file. It will look like this:

//Don't forget the manifest permission to write files
final FileOutputStream fos = new FileOutputStream(yourFileHere); 
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);

fos.close();

final InputStream is = new Base64InputStream( new FileInputStream(yourFileHere) );

//Now that we have the InputStream, we can read it and put it into the String
final StringWriter writer = new StringWriter();
IOUtils.copy(is , writer, encoding);
final String yourBase64String = writer.toString();

As you can see, the above solution works directly with streams instead, avoiding the need to load all the bytes into a variable, therefore making the memory footprint much lower and less likely to crash in low-end devices. There is still the problem that putting the Base64 string itself into a String variable is not a good idea, because, again, it might cause OutOfMemory errors. But at least we have cut the memory consumption by half by eliminating the byte array.

If you want to skip the write-to-a-file step, you have to convert the OutputStream to an InputStream, which is not so straightforward to do (you must use PipedInputStream but that is a little more complex as the two streams must always be in different threads).

Use the -o ConnectTimeout and -o BatchMode=yes -o StrictHostKeyChecking=no .

ConnectTimeout keeps the script from hanging, BatchMode keeps it from hanging with Host unknown, YES to add to known_hosts, and StrictHostKeyChecking adds the fingerprint automatically.

**** NOTE **** The "StrictHostKeyChecking" was only intended for internal networks where you trust you hosts. Depending on the version of the SSH client, the "Are you sure you want to add your fingerprint" can cause the client to hang indefinitely (mainly old versions running on AIX). Most modern versions do not suffer from this issue. If you have to deal with fingerprints with multiple hosts, I recommend maintaining the known_hosts file with some sort of configuration management tool like puppet/ansible/chef/salt/etc.

Up to Postgres 11 generated columns are not supported - as defined in the SQL standard and implemented by some RDBMS including DB2, MySQL and Oracle. Nor the similar "computed columns" of SQL Server.

STORED generated columns are introduced with Postgres 12. Trivial example:

CREATE TABLE tbl (
  int1    int
, int2    int
, product bigint GENERATED ALWAYS AS (int1 * int2) STORED
);

db<>fiddle here

VIRTUAL generated columns may come with one of the next iterations. (Not in Postgres 13, yet) .

Related:

• Attribute notation for function call gives error

Until then, you can emulate VIRTUAL generated columns with a function using attribute notation (tbl.col) that looks and works much like a virtual generated column. That's a bit of a syntax oddity which exists in Postgres for historic reasons and happens to fit the case. This related answer has code examples:

• Store common query as column?

The expression (looking like a column) is not included in a SELECT * FROM tbl, though. You always have to list it explicitly.

Can also be supported with a matching expression index - provided the function is IMMUTABLE. Like:

CREATE FUNCTION col(tbl) ... AS ...  -- your computed expression here
CREATE INDEX ON tbl(col(tbl));

Alternatives

Alternatively, you can implement similar functionality with a VIEW, optionally coupled with expression indexes. Then SELECT * can include the generated column.

"Persisted" (STORED) computed columns can be implemented with triggers in a functionally identical way.

Materialized views are a closely related concept, implemented since Postgres 9.3.
In earlier versions one can manage MVs manually.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

It will work as expected.

One approach is to combine the search strings into a regex pattern as in this answer.

Suppose you have mulitple record for same date or leave_type but different id and you want the maximum no of id for same date or leave_type as i also sucked with this issue, so Yes you can do it with the following query:

select * from tabel_name where employee_no='123' and id=(
   select max(id) from table_name where employee_no='123' and leave_type='5'
)

Im pretty confident that the application you found actually gets their information form Themoviedb.org's API(they get most of there stuff from IMDB). They have a free open API that is used alot of the movie organizer/XMBC applications.

Create a HttpRequestMessage, set the Method to GET, set your headers and then use SendAsync instead of GetAsync.

var client = new HttpClient();
var request = new HttpRequestMessage() {
    RequestUri = new Uri("http://www.someURI.com"),
    Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
var task = client.SendAsync(request)
    .ContinueWith((taskwithmsg) =>
    {
        var response = taskwithmsg.Result;

        var jsonTask = response.Content.ReadAsAsync<JsonObject>();
        jsonTask.Wait();
        var jsonObject = jsonTask.Result;
    });
task.Wait();

The motivation is to write code that doesn't depend explicitly on Spring. That way, if you choose to switch containers, you don't have to rewrite any code.

Think of the container as something is invisible to your code, magically providing for its needs, without being asked.

Dependency injection is a counterpoint to the "service locator" pattern. If you are going to lookup dependencies by name, you might as well get rid of the DI container and use something like JNDI.

I was trying to figure how to do this recently and while I like the most popular solution at the top, it simply would not work for me as I needed the names to be the alias's that I entered in the script so I used some batch files (with some help from a colleague) to accomplish custom table names.

The batch file that initiates the bcp has a line at the bottom of the script that executes another script that merges a template file with the header names and the file that was just exported with bcp using the code below. Hope this helps someone else that was in my situation.

echo Add headers from template file to exported sql files....
Echo School 0031
copy e:\genin\templates\TEMPLATE_Courses.csv + e:\genin\0031\courses0031.csv e:\genin\finished\courses0031.csv /b

Also, if you have Toad for Oracle, you can highlight the statement and press CTRL + F9 and you'll get a nice view of column and their datatypes.

From the package matplotlib.dates as shown in this example the date format can be applied to the axis label and ticks for plot.

Below I have given an example for labeling axis ticks for multiplots

import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import pandas as pd

df = pd.read_csv('US_temp.csv')
plt.plot(df['Date'],df_f['MINT'],label='Min Temp.')
plt.plot(df['Date'],df_f['MAXT'],label='Max Temp.')
plt.legend()
####### Use the below functions #######
dtFmt = mdates.DateFormatter('%b') # define the formatting
plt.gca().xaxis.set_major_formatter(dtFmt) # apply the format to the desired axis
plt.show()

As simple as that

To concatenate two strings in 2008 or prior:

SELECT ISNULL(FirstName, '') + ' ' + ISNULL(SurName, '')

good to use ISNULL because "String + NULL" will give you a NULL only

One more thing: Make sure you are concatenating strings otherwise use a CAST operator:

SELECT 2 + 3 

Will give 5

SELECT '2' + '3'

Will give 23

Use typeof for elements checks.

if(typeof(element) === 'undefined')
{
// then field does not exist
}

this is actually so straight forward, this is my HTML, jQuery sample.. and it works like a charm, I build all the code using an online json data sample. cheers

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

LatLngBounds must be defined with points in (south-west, north-east) order. Your points are not in that order.

The general fix, especially if you don't know the points will definitely be in that order, is to extend an empty bounds:

var bounds = new google.maps.LatLngBounds();
bounds.extend(myPlace);
bounds.extend(Item_1);
map.fitBounds(bounds);

The API will sort out the bounds.

Model

public class Book
{
public string Title {get;set;}
public string Author {get;set;}
}

Controller

public class BookController : Controller
{
     [HttpPost]
     public ActionResult Create(Book model, IEnumerable<HttpPostedFileBase> fileUpload)
     {
         throw new NotImplementedException();
     }
}

And View

@using (Html.BeginForm("Create", "Book", FormMethod.Post, new { enctype = "multipart/form-data" }))
{      
     @Html.EditorFor(m => m)

     <input type="file" name="fileUpload[0]" /><br />      
     <input type="file" name="fileUpload[1]" /><br />      
     <input type="file" name="fileUpload[2]" /><br />      

     <input type="submit" name="Submit" id="SubmitMultiply" value="Upload" />
}

Note title of parameter from controller action must match with name of input elements IEnumerable<HttpPostedFileBase> fileUpload -> name="fileUpload[0]"

fileUpload must match

This doesn't sound intuitive but select the column you're having the issue with and use "text to column" and just press finish. This is the suggested answer from Excel help as well. For some reason in converts text to numbers.

First, I strongly suggest to use a Library or Framework to do your Javascript. But just for something very very simple, or for the fun to learn, it is ok. (you can use jquery, underscore, knockoutjs, angular)

Second, it is not advised to bind directly to onclick, my first suggestion goes in that way too.

That's said What you need is to modify the src of a img in your page.

In the place where you want your image displayed, you should insert a img tag like this:

Next, you need to modify the onclick to update the src attribute. The easiest way I can think of is like his

onclick=""document.getElementById('image-placeholder').src = 'http://webpage.com/images/' + document.getElementById('imagename').value + '.png"

Then again, it is not the best way to do it, but it is a start. I recommend you to try jQuery and see how can you accomplish the same whitout using onclick (tip... check the section on jquery about events)

I did a simple fiddle as a example of your poblem using some google logos... type 4 o 3 in the box and you'll two images of different size. (sorry.. I have no time to search for better images as example)

In short, the goal of __repr__ is to be unambiguous and __str__ is to be readable.

Here is a good example:

>>> import datetime
>>> today = datetime.datetime.now()
>>> str(today)
'2012-03-14 09:21:58.130922'
>>> repr(today)
'datetime.datetime(2012, 3, 14, 9, 21, 58, 130922)'

Read this documentation for repr:

repr(object)

Return a string containing a printable representation of an object. This is the same value yielded by conversions (reverse quotes). It is sometimes useful to be able to access this operation as an ordinary function. For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a __repr__() method.

Here is the documentation for str:

str(object='')

Return a string containing a nicely printable representation of an object. For strings, this returns the string itself. The difference with repr(object) is that str(object) does not always attempt to return a string that is acceptable to eval(); its goal is to return a printable string. If no argument is given, returns the empty string, ''.

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

In Java, using JNA with the Kernel32.dll library, similar to a C++ solution. Runs the CtrlCSender main method as a Process which just gets the console of the process to send the Ctrl+C event to and generates the event. As it runs separately without a console the Ctrl+C event does not need to be disabled and enabled again.

CtrlCSender.java - Based on Nemo1024's and KindDragon's answers.

Given a known process ID, this consoless application will attach the console of targeted process and generate a CTRL+C Event on it.

import com.sun.jna.platform.win32.Kernel32;    

public class CtrlCSender {

    public static void main(String args[]) {
        int processId = Integer.parseInt(args[0]);
        Kernel32.INSTANCE.AttachConsole(processId);
        Kernel32.INSTANCE.GenerateConsoleCtrlEvent(Kernel32.CTRL_C_EVENT, 0);
    }
}

Main Application - Runs CtrlCSender as a separate consoless process

ProcessBuilder pb = new ProcessBuilder();
pb.command("javaw", "-cp", System.getProperty("java.class.path", "."), CtrlCSender.class.getName(), processId);
pb.redirectErrorStream();
pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
pb.redirectError(ProcessBuilder.Redirect.INHERIT);
Process ctrlCProcess = pb.start();
ctrlCProcess.waitFor();

If the function is a void, ending the function will return. Otherwise, you need to do an explicit return someValue. As Mark mentioned, you can also throw an exception. What's the context of your question? Do you have a larger code sample with which to show you some ways to exit the function?

    or

    li.setBackgroundColor(getResources().getColor(android.R.color.red));

Instead of trying to manually align the text into columns with arbitrary strings of spaces, you should embed actual tabs (the \t escape sequence) into each output string:

Console.WriteLine("Customer name" + "\t"
    + "sales" + "\t" 
    + "fee to be paid" + "\t" 
    + "70% value" + "\t" 
    + "30% value");
for (int DisplayPos = 0; DisplayPos < LineNum; DisplayPos++)
{
    seventy_percent_value = ((fee_payable[DisplayPos] / 10.0) * 7);
    thirty_percent_value = ((fee_payable[DisplayPos] / 10.0) * 3);          
    Console.WriteLine(customer[DisplayPos] + "\t" 
        + sales_figures[DisplayPos] + "\t" 
        + fee_payable + "\t\t"
        + seventy_percent_value + "\t\t" 
        + thirty_percent_value);
}

If you're going across machines, you either need to be using NETWORK SERVICE, LOCAL SYSTEM, a domain account, or a SQL 2008 R2 (if you have it) Managed Service Account (which is my preference if you had such an infrastructure). You can not use an account which is not visible to the Active Directory domain.

Walkthrough of creating and deleting an environment variable in bash:

Test if the DUALCASE variable exists:

el@apollo:~$ env | grep DUALCASE
el@apollo:~$ 

It does not, so create the variable and export it:

el@apollo:~$ DUALCASE=1
el@apollo:~$ export DUALCASE

Check if it is there:

el@apollo:~$ env | grep DUALCASE
DUALCASE=1

It is there. So get rid of it:

el@apollo:~$ unset DUALCASE

Check if it's still there:

el@apollo:~$ env | grep DUALCASE
el@apollo:~$ 

The DUALCASE exported environment variable is deleted.

Extra commands to help clear your local and environment variables:

Unset all local variables back to default on login:

el@apollo:~$ CAN="chuck norris"
el@apollo:~$ set | grep CAN
CAN='chuck norris'
el@apollo:~$ env | grep CAN
el@apollo:~$
el@apollo:~$ exec bash
el@apollo:~$ set | grep CAN
el@apollo:~$ env | grep CAN
el@apollo:~$

exec bash command cleared all the local variables but not environment variables.

Unset all environment variables back to default on login:

el@apollo:~$ export DOGE="so wow"
el@apollo:~$ env | grep DOGE
DOGE=so wow
el@apollo:~$ env -i bash
el@apollo:~$ env | grep DOGE
el@apollo:~$

env -i bash command cleared all the environment variables to default on login.

If you are generating a heap of commands to be run, then call that script from a terminal, you can try the following.

sftp login@host < /path/to/command/list

You will then be asked to enter your password (as per normal) however all the commands in the script run after that.

This is clearly not a completely automated option that can be used in a cron job, but it can be used from a terminal.

If you intend to read csv from excel, then there are some interesting corner cases. I can't remember them all, but the apache commons csv was not capable of handling it correctly (with, for example, urls).

Be sure to test excel output with quotes and commas and slashes all over the place.

This answer really helped me get started (noob) - but I encountered some weird behavior when I set a start date of 12/31/2014 and added +1 to default the end date. Instead of giving me an end date of 01/01/2015 I was getting 02/01/2015 (!!!). This version parses the components of the start date to avoid these end of year oddities.

 $( "#date_start" ).datepicker({

   minDate: 0,
   dateFormat: "mm/dd/yy",

   onSelect: function(selected) {
         $("#date_end").datepicker("option","minDate", selected); //  mindate on the End datepicker cannot be less than start date already selected.
         var date = $(this).datepicker('getDate');
         var tempStartDate = new Date(date);
         var default_end = new Date(tempStartDate.getFullYear(), tempStartDate.getMonth(), tempStartDate.getDate()+1); //this parses date to overcome new year date weirdness
         $('#date_end').datepicker('setDate', default_end); // Set as default                           
   }

 });

 $( "#date_end" ).datepicker({

   minDate: 0,
   dateFormat: "mm/dd/yy",

   onSelect: function(selected) {
     $("#date_start").datepicker("option","maxDate", selected); //  maxdate on the Start datepicker cannot be more than end date selected.

  }

});

If the other answers fail, importing it as

import moment from 'moment/moment.js'

may work.

For me this worked:

buildscript {
    repositories {
        maven { url "http://jcenter.bintray.com"}
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
...
}

        }
    }
}

I wanted to do this in React using plain Js and the fetch polyfill. OP didn't say he specifically wanted to create a form and invoke the submit method on it, so I have done it by posting the form values as json:

    headers: {
       'Content-type' : 'application/json',
       'Accept' : 'text/html'
    },

        someList: [1,2,3,4],
        someProperty: 'something',
        someObject: {some: 'object'}
    })
}

asyncPostPopup = () => {

    //open a new window and set some text until the fetch completes
    let win=window.open('about:blank')
    writeToWindow(win,'Loading...')

I searched it in Google and I found this:

The Google Chrome Extension file type is CRX. It is essentially a compression format. So if you want to see what is behind an extension, the scripts and the code, just change the file-type from “CRX” to “ZIP” .

Unzip the file and you will get all the info you need. This way you can see the guts, learn how to write an extension yourself, or modify it for your own needs.

Then you can pack it back up with Chrome’s internal tools which automatically create the file back into CRX. Installing it just requires a click.

$full_path = WP_PLUGIN_URL . '/'. str_replace( basename( __FILE__ ), "", plugin_basename(__FILE__) );

• WP_PLUGIN_URL – the url of the plugins directory
• WP_PLUGIN_DIR – the server path to the plugins directory

When I try:

<input type="button" id="moreFields" onclick="alert('The text will be show!!'); return false;" value="Give me more fields!"  />

It's worked well. So I think the problem is position of moreFields() function. Ensure that function will be define before your input tag.

Pls try:

<script type="text/javascript">
    function moreFields() {
        alert("The text will be show");
    }
</script>

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />

Hope it helped.

I know it's been a long time since the question was asked, but I found the check to be clearer like this :

if ($("#A").is('[myattr]')) {
    // attribute exists
} else {
    // attribute does not exist
}

(As found on this site here)

What exactly are the rules for requesting retransmission of lost data?

The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.

Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ

are detailed in the RFC 3366.

At what time frequency are the retransmission requests performed?

The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)

The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.

Is there an upper bound on the number?

Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.

Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?

The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

If you have a single play that you want to loop over the items, define that list in group_vars/all or somewhere else that makes sense:

all_items:
  - first
  - second
  - third
  - fourth

Then your task can look like this:

  - name: List items or default list
    debug:
      var: item
    with_items: "{{ varlist | default(all_items) }}"

Pass in varlist as a JSON array:

ansible-playbook <playbook_name> --extra-vars='{"varlist": [first,third]}'

Prior to that, you might also want a task that checks that each item in varlist is also in all_items:

  - name: Ensure passed variables are in all_items
    fail:
      msg: "{{ item }} not  in all_items list"
    when: item not in all_items
    with_items: "{{ varlist | default(all_items) }}"

The newer subprocess.check_output and similar commands are supposed to replace os.system. See this page for details. While I can't test this on Windows (because I don't have access to any Windows machines), the following should work:

from subprocess import check_output
check_output("dir C:", shell=True)

check_output returns a string of the output from your command. Alternatively, subprocess.call just runs the command and returns the status of the command (usually 0 if everything is okay).

Also note that, in python 3, that string output is now bytes output. If you want to change this into a string, you need something like

from subprocess import check_output
check_output("dir C:", shell=True).decode()

If necessary, you can tell it the kind of encoding your program outputs. The default is utf-8, which typically works fine, but other standard options are here.

Also note that @bluescorpion says in the comments that Windows 10 needs a trailing backslash, as in check_output("dir C:\\", shell=True). The double backslash is needed because \ is a special character in python, so it has to be escaped. (Also note that even prefixing the string with r doesn't help if \ is the very last character of the string — r"dir C:\" is a syntax error, though r"dir C:\ " is not.)

If EditText is inside Recycler or ListView and/or this have disable state use below code.

public static void showKeyboardByFocus(final View view)
    {
        view.requestFocus();

        InputMethodManager keyboard = SystemMaster.getInputMethodManager();
        keyboard.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);

        Runnable re = new Runnable()
        {
            @Override
            public void run()
            {
                view.setEnabled(true);
                view.requestFocus();
            }
        };

        Handler h = new Handler(Looper.getMainLooper());
        h.postDelayed(re, 360);
    }

I got it

Cells(1, 1).Value = StartDate
Cells(1, 1).NumberFormat = "dd/mm/yyyy"

Basically, I need to set the cell format, instead of setting the date.

Try the sp_foreachdb procedure.

Compounded the problem by deleting the local repo so I could clone a fresh copy. I was faced with new error "git cannot be found Git failed with a fatal error.fatal: repository 'xyz' not found"

I tried everything suggestions i google about with no resolution. The following simple step worked for me and I am adding it to the growing list of possible resolutions:

git config --get http.proxy result is http://google.com:80

this is not right so i got rid of it.

git config --global --unset http.proxy

Make sure that you actually save the file as UTF-8, alternatively use HTML entities (&#nnn;) for the special characters.

I just stumbled on this old post, and while I'm sure user01 has long since found his answer, I found the current answers don't quite work. After playing around for a little bit using info provided by the others, I found a solution that worked in IE, Firefox, and Chrome. In CSS:

html, body {
    height: 100%;
}

html {
    display: table;
    margin: auto;
}

body {
    display: table-cell;
    vertical-align: middle;
}

This is almost identical to abernier's answer, but I found that including width would break the centering, as would omitting the auto margin. I hope anyone else who stumbles on this thread will find my answer helpful.

Note: Omit html, body { height: 100%; } to only center horizontally.

Well, file_exists does not say if a file exists, it says if a path exists. ???????

So, to check if it is a file then you should use is_file together with file_exists to know if there is really a file behind the path, otherwise file_exists will return true for any existing path.

Here is the function i use :

function fileExists($filePath)
{
      return is_file($filePath) && file_exists($filePath);
}

Two possible answers:

1- You did not include spring-beans and spring-context jars in your lib. If you are using maven (which will help a lot) those two lines will be enough

<dependency>
 <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
   <version>3.1.0.RELEASE</version>
</dependency>
<dependency>
 <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
   <version>3.1.0.RELEASE</version>
</dependency>

2- The necessary jars are in your classpath but are not deployed on tomcat.

I use:

int myint = 0;
long double myLD = 0.0;

string myint_str = static_cast<ostringstream*>(&(ostringstream() << myint))->str();
string myLD_str = static_cast<ostringstream*>(&(ostringstream() << myLD))->str();

It works on my Windows and Linux g++ compilers.

Maybe try the Intl polyfill for IE8 or the olyfill service ?

or

https://github.com/andyearnshaw/Intl.js/

Try MySQL Workbench. It packs in very nice data modeling tools. Check out their screenshots for EER diagrams (Enhanced Entity Relationships, which are a notch up ER diagrams).

This isn't CakePHP specific, but you can modify the options so that the foreign keys and join tables follow the conventions that CakePHP uses. This would simplify your data modeling process once you've put the rules in place.

onCreate(Bundle savedInstanceState) you will get the Bundle null when activity get starts first time and it will get in use when activity orientation get changed .......

http://www.gitshah.com/2011/03/how-to-handle-screen-orientation_28.html

Android provides another elegant way of achieving this. To achieve this, we have to override a method called onSaveInstanceState(). Android platform allows the users to save any instance state. Instance state can be saved in the Bundle. Bundle is passed as argument to the onSaveInstanceState method.

we can load the saved instance state from the Bundle passed as argument to the onCreate method. We can also load the saved instance state in onRestoreInstanceState method. But I will leave that for the readers to figure out.

Some interesting timings regarding all these methods. If you have Gigabit connections, you should not use the /z flag or it will kill your connection speed. Robocopy or dism are the only tools that go full speed and show a progress bar. wdscase is for multicasting off a WDS server and might be faster if you are imaging 5+ computers. To get the 1:17 timing, I was maxing out the Gigabit connection at 920Mbps so you won't get that on two connections at once. Also take note that exporting the small wim index out of the larger wim file too longer than just copying the whole thing.

If you don't have robocopy.exe available, why not run it from the network share you are copying your files from? In my case, I prefer to do that so I don't have to rebuild my WinPE boot.wim file every time I want to make a change and then update dozens of flash drives.

Just install cache eraser plugin, it is compatible with nb6.9, 7.0,7.1,7.2 and 7.3: To configure the plugin you have to provide the cache dir which is in netbean's about screen. Then with Tools->erase cache, you clear the netbeans cache. That is all, good luck.

If you don't wont use jquery.ui(that is highly recommended), you can take a look at Block.UI plugin.

We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration. -- jQuery.each() | jQuery API Documentation

namedtuples are immutable, just like standard tuples. You have two choices:

1. Use a different data structure, e.g. a class (or just a dictionary); or
2. Instead of updating the structure, replace it.

The former would look like:

class N(object):

    def __init__(self, ind, set, v):
        self.ind = ind
        self.set = set
        self.v = v

And the latter:

item = items[node.ind]
items[node.ind] = N(item.ind, item.set, node.v)

Edit: if you want the latter, Ignacio's answer does the same thing more neatly using baked-in functionality.

Type history in your terminal. It's not technically git, but I think it is what you want.

safeAreaLayoutGuide When the view is visible onscreen, this guide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. (In tvOS, the safe area reflects the area not covered the screen's bezel.) If the view is not currently installed in a view hierarchy, or is not yet visible onscreen, the layout guide edges are equal to the edges of the view.

Then to get the height of the red arrow in the screenshot it's:

self.safeAreaLayoutGuide.layoutFrame.size.height

Yeah, the best way is to convert the object notation to a flat key-value string representation, as mentioned in this comment: https://stackoverflow.com/a/39357531/2529199

I wanted to highlight an alternative method using this NPM library: https://www.npmjs.com/package/dot-object which lets you manipulate different objects using dot notation.

I used this pattern to programatically create a nested object property when accepting the key-value as a function variable, as follows:

const dot = require('dot-object');

function(docid, varname, varvalue){
  let doc = dot.dot({
      [varname]: varvalue 
  });

  Mongo.update({_id:docid},{$set:doc});
}

This pattern lets me use nested as well as single-level properties interchangeably, and insert them cleanly into Mongo.

If you need to play around with JS Objects beyond just Mongo, especially on the client-side but have consistency when working with Mongo, this library gives you more options than the earlier mentioned mongo-dot-notation NPM module.

P.S I originally wanted to just mention this as a comment but apparently my S/O rep isn't high enough to post a comment. So, not trying to muscle in on SzybkiSasza's comment, just wanted to highlight providing an alternative module.

The problem here is that you are including commands.c in commands.h before the function prototype. Therefore, the C pre-processor inserts the content of commands.c into commands.h before the function prototype. commands.c contains the function definition. As a result, the function definition ends up before than the function declaration causing the error.

The content of commands.h after the pre-processor phase looks like this:

#ifndef COMMANDS_H_
#define COMMANDS_H_

// function definition
void f123(){

}

// function declaration
void f123();

#endif /* COMMANDS_H_ */

This is an error because you can't declare a function after its definition in C. If you swapped #include "commands.c" and the function declaration the error shouldn't happen because, now, the function prototype comes before the function declaration.

However, including a .c file is a bad practice and should be avoided. A better solution for this problem would be to include commands.h in commands.c and link the compiled version of command to the main file. For example:

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123(); // function declaration

#endif

commands.c

#include "commands.h"

void f123(){} // function definition

document.getElementById("elementID").scrollIntoView();

Same thing, but wrapping it in a function:

function scrollIntoView(eleID) {
   var e = document.getElementById(eleID);
   if (!!e && e.scrollIntoView) {
       e.scrollIntoView();
   }
}

This even works in an IFrame on an iPhone.

Example of using getElementById: http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_document_getelementbyid

those icons are a way of Egit to show you status of the current file/folder in git. You might want to check this out:

• dirty (folder) - At least one file below the folder is dirty; that means that it has changes in the working tree that are neither in the index nor in the repository.
• tracked - The resource is known to the Git repository. untracked - The resource is not known to the Git repository.
• ignored - The resource is ignored by the Git team provider. Here only the preference settings under Team -> Ignored Resources and the "derived" flag are relevant. The .gitignore file is not taken into account.
• dirty - The resource has changes in the working tree that are neither in the index nor in the repository.
• staged - The resource has changes which are added to the index. Not that adding to the index is possible at the moment only on the commit dialog on the context menu of a resource.
• partially-staged - The resource has changes which are added to the index and additionally changes in the working tree that are neither in the index nor in the repository.
• added - The resource is not yet tracked by but added to the Git repository.
• removed - The resource is staged for removal from the Git repository.
• conflict - A merge conflict exists for the file.
• assume-valid - The resource has the "assume unchanged" flag. This means that Git stops checking the working tree files for possible modifications, so you need to manually unset the bit to tell Git when you change the working tree file. This setting can be switched on with the menu action Team->Assume unchanged (or on the command line with git update-index--assume-unchanged).

....but $('span', $('#foo')); doesn't work?

This method is called as providing selector context.

In this you provide a second argument to the jQuery selector. It can be any css object string just like you would pass for direct selecting or a jQuery element.

eg.

$("span",".cont1").css("background", '#F00');

The above line will select all spans within the container having the class named cont1.

You can't take a screen-shot: it would be an irresponsible security risk to let you do so. However, you can:

• Do things server-side and generate an image
• Draw something similar to a Canvas and render that to an image (in a browser that supports it)
• Use some other drawing library to draw directly to the image (slow, but would work on any browser)

I had to do something similar for work, but in my case I had to filter all that is not a letter, number or whitespace (but you could easily modify it to your needs). The filtering is done client-side in JavaScript, but for security reasons I am also doing the filtering server-side. Since I can expect most of the strings to be clean, I would like to avoid copying the string unless I really need to. This let my to the implementation below, which should perform better for both clean and dirty strings.

public static string EnsureOnlyLetterDigitOrWhiteSpace(string input)
{
    StringBuilder cleanedInput = null;
    for (var i = 0; i < input.Length; ++i)
    {
        var currentChar = input[i];
        var charIsValid = char.IsLetterOrDigit(currentChar) || char.IsWhiteSpace(currentChar);

        if (charIsValid)
        {
            if(cleanedInput != null)
                cleanedInput.Append(currentChar);
        }
        else
        {
            if (cleanedInput != null) continue;
            cleanedInput = new StringBuilder();
            if (i > 0)
                cleanedInput.Append(input.Substring(0, i));
        }
    }

    return cleanedInput == null ? input : cleanedInput.ToString();
}

Got into the same predicament. I ended up with the following. So here I am not injecting the scope object into the factory, but setting the $scope in the controller itself using the concept of promise returned by $http service.

(function () {
    getDataFactory = function ($http)
    {
        return {
            callWebApi: function (reqData)
            {
                var dataTemp = {
                    Page: 1, Take: 10,
                    PropName: 'Id', SortOrder: 'Asc'
                };

                return $http({
                    method: 'GET',
                    url: '/api/PatientCategoryApi/PatCat',
                    params: dataTemp, // Parameters to pass to external service
                    headers: { 'Content-Type': 'application/Json' }
                })                
            }
        }
    }
    patientCategoryController = function ($scope, getDataFactory) {
        alert('Hare');
        var promise = getDataFactory.callWebApi('someDataToPass');
        promise.then(
            function successCallback(response) {
                alert(JSON.stringify(response.data));
                // Set this response data to scope to use it in UI
                $scope.gridOptions.data = response.data.Collection;
            }, function errorCallback(response) {
                alert('Some problem while fetching data!!');
            });
    }
    patientCategoryController.$inject = ['$scope', 'getDataFactory'];
    getDataFactory.$inject = ['$http'];
    angular.module('demoApp', []);
    angular.module('demoApp').controller('patientCategoryController', patientCategoryController);
    angular.module('demoApp').factory('getDataFactory', getDataFactory);    
}());

I had an array of strings, not objects and i used this approach:

ng-repeat="name in names | unique"

with this filter:

angular.module('app').filter('unique', unique);
function unique(){
return function(arry){
        Array.prototype.getUnique = function(){
        var u = {}, a = [];
        for(var i = 0, l = this.length; i < l; ++i){
           if(u.hasOwnProperty(this[i])) {
              continue;
           }
           a.push(this[i]);
           u[this[i]] = 1;
        }
        return a;
    };
    if(arry === undefined || arry.length === 0){
          return '';
    }
    else {
         return arry.getUnique(); 
    }

  };
}

For Windows. Run these commands in Git Bash:

git config --global diff.tool meld
git config --global difftool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"
git config --global difftool.prompt false

git config --global merge.tool meld
git config --global mergetool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"
git config --global mergetool.prompt false

(Update the file path for Meld.exe if yours is different.)

For Linux. Run these commands in Git Bash:

git config --global diff.tool meld
git config --global difftool.meld.path "/usr/bin/meld"
git config --global difftool.prompt false

git config --global merge.tool meld
git config --global mergetool.meld.path "/usr/bin/meld"
git config --global mergetool.prompt false

You can verify Meld's path using this command:

which meld

I encountered same problem when I upgraded from Windows 7 to 10. Eventually I have to re-install SVN and reboot the system and it worked. However, I have to manually upgrade each SVN directory to new SVN 1.8 format (it showed up automatically on explorer on right click to upgrade the directory to latest version). Hope this helps.

I wanted the same thing; a delete button on my Details view. I eventually realised I needed to post from that view:

@using (Html.BeginForm())
        {
            @Html.AntiForgeryToken()
            @Html.HiddenFor(model => model.Id)
            @Html.ActionLink("Edit", "Edit", new { id = Model.Id }, new { @class = "btn btn-primary", @style="margin-right:30px" })

            <input type="submit" value="Delete" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this record?');" />
        }

And, in the Controller:

 // this action deletes record - called from the Delete button on Details view
    [HttpPost]
    public ActionResult Details(MainPlus mainPlus)
    {
        if (mainPlus != null)
        {
            try
            {
                using (IDbConnection db = new SqlConnection(PCALConn))
                {
                    var result = db.Execute("DELETE PCAL.Main WHERE Id = @Id", new { Id = mainPlus.Id });
                }
                return RedirectToAction("Calls");
            } etc

Don't use exit(0); That's bad practice at the best of times. Use Yii::$app->end();

So your code would look like

$this->redirect(['index'], 302);
Yii::$app->end();

That said though the actual problem was stopping POST requests, this is the wrong solution to that problem (although it does work). To stop POST requests you need to use access control.

public function behaviors()
{
    return [
        'access' => [
            'class' => \yii\filters\AccessControl::className(),
            'only' => ['create', 'update'],
            'rules' => [
                // deny all POST requests
                [
                    'allow' => false,
                    'verbs' => ['POST']
                ],
                // allow authenticated users
                [
                    'allow' => true,
                    'roles' => ['@'],
                ],
                // everything else is denied
            ],
        ],
    ];
}

<input [ngModel]="item.value | useMyPipeToFormatThatValue" 
      (ngModelChange)="item.value=$event" name="inputField" type="text" />

The solution here is to split the binding into a one-way binding and an event binding - which the syntax [(ngModel)] actually encompasses. [] is one-way binding syntax and () is event binding syntax. When used together - [()] Angular recognizes this as shorthand and wires up a two-way binding in the form of a one-way binding and an event binding to a component object value.

The reason you cannot use [()] with a pipe is that pipes work only with one-way bindings. Therefore you must split out the pipe to only operate on the one-way binding and handle the event separately.

See Angular Template Syntax for more info.

You can try using the gitzip extension for chrome, its super easy to use and has helped me download many folders before too!

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

It's been years since the question was asked and was answered.

Project will effects Columns in the table while Select effects the Rows. on other hand Project is use to select the columns with specefic properties rather than Select the all of columns data

The ul.nav li is more restrictive and so takes precedence, try this:

ul.nav li.selected {  
  background-color:red; 
}

Try using style for th

th {text-align:center}

Building on Habib's answer, you could write an extension method:

public static bool ValidateJSON(this string s)
{
    try
    {
        JToken.Parse(s);
        return true;
    }
    catch (JsonReaderException ex)
    {
        Trace.WriteLine(ex);
        return false;
    }
}

Which can then be used like this:

if(stringObject.ValidateJSON())
{
    // Valid JSON!
}

This depends on what content do you have. You need to initialize your requestMessage.Content property with new HttpContent. For example:

...
// Add request body
if (isPostRequest)
{
    requestMessage.Content = new ByteArrayContent(content);
}
...

where content is your encoded content. You also should include correct Content-type header.

UPDATE:

Oh, it can be even nicer (from this answer):

requestMessage.Content = new StringContent("{\"name\":\"John Doe\",\"age\":33}", Encoding.UTF8, "application/json");

You need to use the reserve function to set an initial allocated size or do it in the initial constructor.

vector<CustomClass *> content(20000);

or

vector<CustomClass *> content;
...
content.reserve(20000);

When you reserve() elements, the vector will allocate enough space for (at least?) that many elements. The elements do not exist in the vector, but the memory is ready to be used. This will then possibly speed up push_back() because the memory is already allocated.

display: flex

.container {
  display: flex;
  justify-content: center;
}

Notes:

• It’s not a hack
• Browser support: flexbox

max-width & margin

You can horizontally center a block-level element by assigning a fixed width and setting margin-right and margin-left to auto.

.container ul {
  /* for IE below version 7 use `width` instead of `max-width` */
  max-width: 800px;
  margin-right: auto;
  margin-left: auto;
}

Notes:

• No container needed
• Requires (maximum) width of the centered element to be known

IE9+: transform: translatex(-50%) & left: 50%

This is similar to the quirky centering method which uses absolute positioning and negative margins.

.container {
  position: relative;
}

.container ul {
  position: absolute;
  left: 50%;
  transform: translatex(-50%);
}

Notes:

• The centered element will be removed from document flow. All elements will completely ignore of the centered element.
• This technique allows vertical centering by using top instead of left and translateY() instead of translateX(). The two can even be combined.
• Browser support: transform2d

IE8+: display: table & margin

Just like the first solution, you use auto values for right and left margins, but don’t assign a width. If you don’t need to support IE7 and below, this is better suited, although it feels kind of hacky to use the table property value for display.

.container ul {
  display: table;
  margin-right: auto;
  margin-left: auto;
}

IE8+: display: inline-block & text-align

Centering an element just like you would do with regular text is possible as well. Downside: You need to assign values to both a container and the element itself.

.container {
  text-align: center;
}

.container ul {
  display: inline-block;

  /* One most likely needs to realign flow content */
  text-align: initial;
}

Notes:

• Does not require to specify a (maximum) width
• Aligns flow content to the center (potentially unwanted side effect)
• Works kind of well with a dynamic number of menu items (i.e. in cases where you can’t know the width a single item will take up)

while installing python packages in a global environment is doable, it is a best practice to isolate the environment between projects (creating virtual environments). Otherwise, confusion between Python versions will arise, just like your problem.

The simplest method is to use venv library in the project directory:

python3 -m venv venv

Where the first venv is to call the venv package, and the second venv defines the virtual environment directory name. Then activate the virtual environment:

source venv/bin/activate

Once the virtual environment has been activated, your pip install ... commands would not be interfered with any other Python version or pip version anymore. For installing requests:

pip install requests

Another benefit of the virtual environment is to have a concise list of libraries needed for that specific project.

*note: commands only work on Linux and Mac OS

Use regex pattern ^(?=.{8})(?=.*[^a-zA-Z])

Explanation:

^(?=.{8})(?=.*[^a-zA-Z])
¦+------++-------------+
¦   ¦           ¦
¦   ¦           + string contains some non-letter character
¦   ¦
¦   + string contains at least 8 characters
¦
+ begining of line/string

If you want to limit also maximum length (let's say 16), then use regex pattern:

^(?=.{8,16}$)(?=.*[^a-zA-Z])

This can be done with a single statement and some XML magic:

select table_name, 
       to_number(extractvalue(xmltype(dbms_xmlgen.getxml('select count(*) c from '||owner||'.'||table_name)),'/ROWSET/ROW/C')) as count
from all_tables
where owner = 'FOOBAR'

Flash still has the ASO file, which is the compiled byte code for your classes. On Windows, you can see the ASO files here:

C:\Documents and Settings\username\Local Settings\Application Data\Adobe\Flash CS4\en\Configuration\Classes\aso

On a Mac, the directory structure is similar in /Users/username/Library/Application Support/

You can remove those files by hand, or in Flash you can select Control->Delete ASO files to remove them.

This will probably be added in coming updates. But in the meantime, to accomplish this you can use reflection.

Create a custom view extending from BottomNavigationView and access some of its fields.

public class SelectableBottomNavigationView extends BottomNavigationView {

    public SelectableBottomNavigationView(Context context) {
        super(context);
    }

    public SelectableBottomNavigationView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SelectableBottomNavigationView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public void setSelected(int index) {
        try {
            Field f = BottomNavigationView.class.getDeclaredField("mMenuView");
            f.setAccessible(true);
            BottomNavigationMenuView menuView = (BottomNavigationMenuView) f.get(this);

            try {
                Method method = menuView.getClass().getDeclaredMethod("activateNewButton", Integer.TYPE);
                method.setAccessible(true);
                method.invoke(menuView, index);
            } catch (SecurityException | NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
                e.printStackTrace();
            }
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        }
    }

}

And then use it in your xml layout file.

<com.your.app.SelectableBottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:itemBackground="@color/primary"
        app:itemIconTint="@drawable/nav_item_color_state"

Loads of answers here, but haven't seen the one I use:

input[type="text"]:read-only { color: blue; }

Note the dash in the pseudo selector. If the input is readonly="false" it'll catch that too since this selector catches the presence of readonly regardless of the value. Technically false is invalid according to specs, but the internet is not a perfect world. If you need to cover that case, you can do this:

input[type="text"]:read-only:not([read-only="false"]) { color: blue; }

textarea works the same way:

textarea:read-only:not([read-only="false"]) { color: blue; }

Keep in mind that html now supports not only type="text", but a slew of other textual types such a number, tel, email, date, time, url, etc. Each would need to be added to the selector.

If all you have is the iterator, then no, there is no "better" way. If the iterator comes from a collection you could as that for size.

Keep in mind that Iterator is just an interface for traversing distinct values, you would very well have code such as this

    new Iterator<Long>() {
        final Random r = new Random();
        @Override
        public boolean hasNext() {
            return true;
        }

        @Override
        public Long next() {
            return r.nextLong();
        }

        @Override
        public void remove() {
            throw new IllegalArgumentException("Not implemented");
        }
    };

or

    new Iterator<BigInteger>() {
        BigInteger next = BigInteger.ZERO;

        @Override
        public boolean hasNext() {
            return true;
        }

        @Override
        public BigInteger next() {
            BigInteger current = next;
            next = next.add(BigInteger.ONE);
            return current;
        }

        @Override
        public void remove() {
            throw new IllegalArgumentException("Not implemented");
        }
    }; 

You can convert type of plaintext to string:

f.write(str(plaintext) + '\n')

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

I don't see how that's not elegant, but if you repeat the expression often, then it's a good idea to put it into a method, e.g.

class MathUtil
{
   public static boolean betweenExclusive(int x, int min, int max)
   {
       return x>min && x<max;    
   }
}

This is particularly true if you mix exclusive and inclusive comparisons. The method name can help avoid typos, such as using < when <= should have been used. The method can also take care of ensuring that min < max etc..

You can get information about which volumes were specifically baked into the container by inspecting the container and looking in the JSON output and comparing a couple of the fields. When you run docker inspect myContainer, the Volumes and VolumesRW fields give you information about ALL of the volumes mounted inside a container, including volumes mounted in both the Dockerfile with the VOLUME directive, and on the command line with the docker run -v command. However, you can isolate which volumes were mounted in the container using the docker run -v command by checking for the HostConfig.Binds field in the docker inspect JSON output. To clarify, this HostConfig.Binds field tells you which volumes were mounted specifically in your docker run command with the -v option. So if you cross-reference this field with the Volumes field, you will be able to determine which volumes were baked into the container using VOLUME directives in the Dockerfile.

A grep could accomplish this like:

$ docker inspect myContainer | grep -C2 Binds
...
"HostConfig": {
    "Binds": [
        "/var/docker/docker-registry/config:/registry"
    ],

And...

$ docker inspect myContainer | grep -C3 -e "Volumes\":"
...
"Volumes": {
    "/data": "/var/lib/docker...",
    "/config": "/var/lib/docker...",
    "/registry": "/var/docker/docker-registry/config"

And in my example, you can see I've mounted /var/docker/docker-registry/config into the container as /registry using the -v option in my docker run command, and I've mounted the /data and /config volumes using the VOLUME directive in my Dockerfile. The container does not need to be running to get this information, but it needs to have been run at least one time in order to populate the HostConfig JSON output of your docker inspect command.
