Problem Cause : The process of the current program is still running without interuption. (This is the reason why you haven't got this issue after a restart)

The fix is simple : Go to cmd and type the command taskkill -im process-name.exe -f

Eg:

 taskkill -im demo.exe -f

here,

demo - is my program name

It seems to work fine in Postgresql 9.5:

SELECT current_setting('TIMEZONE');

The cause to this error is usually because you're probably using a bootstrap framework and have already included a jquery file somewhere else may at the head or right above the closing body tag, in that case all you need to do is to include the jquery ui file wherever you have the jquery file or on both both places and you'll be fine...

  <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js" type="text/javascript"></script>

just include the above jquery ui script wherever you are importing the jquery file along with other bootstrap dependencies.

Seems a timestamp issue. According to tomcat documentation, if there is a new jsp or servlet this will create a new _java file in the work folder unless the _java.class files are newer than the jsp or servlets.

You are giving multiple Content-Type headers. application/vnd.ms-excel is enough.

And there are couple of syntax error too. To statement termination with ; on the echo statement and wrong filename extension.

header("Content-Type:   application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=abc.xls");  //File name extension was wrong
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
echo "Some Text"; //no ending ; here

If you don't mind adding a dependency, you can use JsonPath.

import com.jayway.jsonpath.JsonPath;

String firstName = JsonPath.read(rawJsonString, "$.detail.first_name");

"$" specifies the root of the raw json string and then you just specify the path to the field you want. This will always return a string. You'll have to do any casting yourself.

Be aware that it'll throw a PathNotFoundException at runtime if the path you specify doesn't exist.

sequenceName is the name of the sequence in the DB. This is how you specify a sequence that already exists in the DB. If you go this route, you have to specify the allocationSize which needs to be the same value that the DB sequence uses as its "auto increment".

Usage:

@GeneratedValue(generator="my_seq")
@SequenceGenerator(name="my_seq",sequenceName="MY_SEQ", allocationSize=1)

If you want, you can let it create a sequence for you. But to do this, you must use SchemaGeneration to have it created. To do this, use:

@GeneratedValue(strategy=GenerationType.SEQUENCE)

Also, you can use the auto-generation, which will use a table to generate the IDs. You must also use SchemaGeneration at some point when using this feature, so the generator table can be created. To do this, use:

@GeneratedValue(strategy=GenerationType.AUTO)

UPDATE: As of compose file version 3.5:

This now works:

version: "3.5"
services:
  proxy:
    image: hello-world
    ports:
      - "80:80"
    networks:
      - proxynet

networks:
  proxynet:
    name: custom_network

docker-compose up -d will join a network called 'custom_network'. If it doesn't exist, it will be created!

root@ubuntu-s-1vcpu-1gb-tor1-01:~# docker-compose up -d
Creating network "custom_network" with the default driver
Creating root_proxy_1 ... done

Now, you can do this:

version: "2"
services:
  web:
    image: hello-world
    networks:
      - my-proxy-net
networks:
  my-proxy-net:
    external:
      name: custom_network

This will create a container that will be on the external network.

I can't find any reference in the docs yet but it works!

At the time of this writing (which is with SonarQube 4.5.1), the correct property to set is sonar.coverage.exclusions, e.g.:

<properties>
    <sonar.coverage.exclusions>foo/**/*,**/bar/*</sonar.coverage.exclusions>
</properties>

This seems to be a change from just a few versions earlier. Note that this excludes the given classes from coverage calculation only. All other metrics and issues are calculated.

In order to find the property name for your version of SonarQube, you can try going to the General Settings section of your SonarQube instance and look for the Code Coverage item (in SonarQube 4.5.x, that's General Settings → Exclusions → Code Coverage). Below the input field, it gives the property name mentioned above ("Key: sonar.coverage.exclusions").

In Kotlin or in ConstraintLayout you just add :

android:windowSoftInputMode="stateHidden|adjustResize"

OR

android:windowSoftInputMode="stateVisible|adjustResize"

Which state you need after activity launch, you can set from manifest.

in your AndroidManifest.xml like this:

      <activity
        android:name=".ActivityName"
        android:windowSoftInputMode="stateHidden|adjustResize"
        />

If you want the month year unique pair, using apply is pretty sleek.

df['mnth_yr'] = df['date_column'].apply(lambda x: x.strftime('%B-%Y')) 

Outputs month-year in one column.

Don't forget to first change the format to date-time before, I generally forget.

df['date_column'] = pd.to_datetime(df['date_column'])

I think that what you have to check is:

1. if the target EXE is correctly configured in the project settings ("command", in the debugging tab). Since all individual projects run when you start debugging it's well possible that only the debugging target for the "ALL" solution is missing, check which project is currently active (you can also select the debugger target by changing the active project).

2. dependencies (DLLs) are also located at the target debugee directory or can be loaded (you can use the "depends.exe" tool for checking dependencies of an executable or DLL).

A span tag is only as wide as its contents, so there is no 'center' of a span tag. There is no extra space on either side of the content.

A div tag, however, is as wide as its containing element, so the content of that div can be centered using any extra space that the content doesn't take up.

So if your div is 100px width and your content only takes 50px, the browser will divide the remaining 50px by 2 and pad 25px on each side of your content to center it.

SHA and AES serve different purposes. SHA is used to generate a hash of data and AES is used to encrypt data.

Here's an example of when an SHA hash is useful to you. Say you wanted to download a DVD ISO image of some Linux distro. This is a large file and sometimes things go wrong - so you want to validate that what you downloaded is correct. What you would do is go to a trusted source (such as the offical distro download point) and they typically have the SHA hash for the ISO image available. You can now generated the comparable SHA hash (using any number of open tools) for your downloaded data. You can now compare the two hashs to make sure they match - which would validate that the image you downloaded is correct. This is especially important if you get the ISO image from an untrusted source (such as a torrent) or if you are having trouble using the ISO and want to check if the image is corrupted.

As you can see in this case the SHA has was used to validate data that was not corrupted. You have every right to see the data in the ISO.

AES, on the other hand, is used to encrypt data, or prevent people from viewing that data with knowing some secret.

AES uses a shared key which means that the same key (or a related key) is used to encrypted the data as is used to decrypt the data. For example if I encrypted an email using AES and I sent that email to you then you and I would both need to know the shared key used to encrypt and decrypt the email. This is different than algorithms that use a public key such PGP or SSL.

If you wanted to put them together you could encrypt a message using AES and then send along an SHA1 hash of the unencrypted message so that when the message was decrypted they were able to validate the data. This is a somewhat contrived example.

If you want to know more about these some Wikipedia search terms (beyond AES and SHA) you want want to try include:

Symmetric-key algorithm (for AES) Cryptographic hash function (for SHA) Public-key cryptography (for PGP and SSL)

If you are on Windows Vista +, then try this Powershell method:

For /F %%L in ('Powershell $Env:MY_STRING.Length') do (
    Set MY_STRING_LEN=%%L
)

or alternatively:

Powershell $Env:MY_STRING.Length > %Temp%\TmpFile.txt
Set /p MY_STRING_LEN = < %Temp%\TmpFile.txt
Del %Temp%\TmpFile.txt

I'm on Windows 7 x64 and this is working for me.

Faced the same problem. Probably it could be a solution:

<select id="select-1">
    <option>One</option>
    <option>Two</option>
    <option>Three</option>
</select>
<label for="select-1"></label>

#select-1 {
    ...
}

#select-1 + label:after {
    ...
}

You can also use this as a comment:

<?php

You can do this by displaying a div (if you want to do it in a modal manner you could use blockUI - or one of the many other modal dialog plugins out there) prior to the request then just waiting until the call back succeeds as a quick example you can you $.getJSON as follows (you might want to use .ajax if you want to add proper error handling)

$("#ajaxLoader").show(); //Or whatever you want to do
$.getJSON("/AJson/Call/ThatTakes/Ages", function(result) {
    //Process your response
    $("#ajaxLoader").hide();
});

If you do this several times in your app and want to centralise the behaviour for all ajax calls you can make use of the global AJAX events:-

$("#ajaxLoader").ajaxStart(function() { $(this).show(); })
               .ajaxStop(function() { $(this).hide(); });

Using blockUI is similar for example with mark up like:-

<a href="/Path/ToYourJson/Action" id="jsonLink">Get JSON</a>
<div id="resultContainer" style="display:none">
And the answer is:-
    <p id="result"></p>
</div>

<div id="ajaxLoader" style="display:none">
    <h2>Please wait</h2>
    <p>I'm getting my AJAX on!</p>
</div>

And using jQuery:-

$(function() {
    $("#jsonLink").click(function(e) {
        $.post(this.href, function(result) {
            $("#resultContainer").fadeIn();
            $("#result").text(result.Answer);
        }, "json");
        return false;
    });
    $("#ajaxLoader").ajaxStart(function() {
                          $.blockUI({ message: $("#ajaxLoader") });
                     })
                    .ajaxStop(function() { 
                          $.unblockUI();
                     });
});

Your users can still change their passwords by "alter user onlyTheirUserName identified by newpassword". They do not have to have the ALTER USER privilege to change their own password.

Excel has no way of gathering that attribute with it's built-in functions. If you're willing to use some VB, all your color-related questions are answered here:

http://www.cpearson.com/excel/colors.aspx

Example form the site:

The SumColor function is a color-based analog of both the SUM and SUMIF function. It allows you to specify separate ranges for the range whose color indexes are to be examined and the range of cells whose values are to be summed. If these two ranges are the same, the function sums the cells whose color matches the specified value. For example, the following formula sums the values in B11:B17 whose fill color is red.

=SUMCOLOR(B11:B17,B11:B17,3,FALSE)

I will tell , how i solved almost similar problem. I developed a application using VS 2013 and tried to create wizard for it failed to do. Later i installed premium VS and tried and failed.

at last i used "ClickOnce" and it worked fine.

So i believe here also , "CLICKONCE" would help you.

@PropertySource can be configured by factory argument. So you can do something like:

@PropertySource(value = "classpath:application-test.yml", factory = YamlPropertyLoaderFactory.class)

Where YamlPropertyLoaderFactory is your custom property loader:

public class YamlPropertyLoaderFactory extends DefaultPropertySourceFactory {
    @Override
    public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException {
        if (resource == null){
            return super.createPropertySource(name, resource);
        }

        return new YamlPropertySourceLoader().load(resource.getResource().getFilename(), resource.getResource(), null);
    }
}

Prior to Microsoft introducing their new "Linux subsystem for Windows" option, CreateProcess() was the closest thing Windows has to fork(), but Windows requires you to specify an executable to run in that process.

The UNIX process creation is quite different to Windows. Its fork() call basically duplicates the current process almost in total, each in their own address space, and continues running them separately. While the processes themselves are different, they are still running the same program. See here for a good overview of the fork/exec model.

Going back the other way, the equivalent of the Windows CreateProcess() is the fork()/exec() pair of functions in UNIX.

If you were porting software to Windows and you don't mind a translation layer, Cygwin provided the capability that you want but it was rather kludgey.

Of course, with the new Linux subsystem, the closest thing Windows has to fork() is actually fork() :-)

I had trouble with SQLite3, nStore and Alfred.

What works for me is node-dirty:

path = "#{__dirname}/data/messages.json"
messages = db path

message = 'text': 'Lorem ipsum dolor sit...'

messages.on "load", ->    
    messages.set 'my-unique-key', message, ->
        console.log messages.get('my-unique-key').text

    messages.forEach (key, value) ->
        console.log "Found key: #{key}, val: %j", value

messages.on "drain", ->
    console.log "Saved to #{path}"

This solution worked for me:

var rawBodySaver = function (req, res, buf, encoding) {
  if (buf && buf.length) {
    req.rawBody = buf.toString(encoding || 'utf8');
  }
}

app.use(bodyParser.json({ verify: rawBodySaver }));
app.use(bodyParser.urlencoded({ verify: rawBodySaver, extended: true }));
app.use(bodyParser.raw({ verify: rawBodySaver, type: '*/*' }));

When I use solution with req.on('data', function(chunk) { }); it not working on chunked request body.

Use the above command to get the commitid, hope this helps.

The official naming conventions aren't that strict, they don't even 'forbid' camel case notation except for prefix (com in your example).

But I personally would avoid upper case letters and hyphenations, even numbers. I'd choose com.stackoverflow.mypackage like Bragboy suggested too.

(hyphenations '-' are not legal in package names)

EDIT

Interesting - the language specification has something to say about naming conventions too.

In Chapter 7.7 Unique Package Names we see examples with package names that consist of upper case letters (so CamelCase notation would be OK) and they suggest to replace hyphonation by an underscore ("mary-lou" -> "mary_lou") and prefix java keywords with an underscore ("com.example.enum" -> "com.example._enum")

Some more examples for upper case letters in package names can be found in chapter 6.8.1 Package Names.

You need to set basicHttpBinding -> MaxReceivedMessageSize in the client configuration.

You need to use runat="server" like this:

<textarea id="TextArea1" cols="20" rows="2" runat="server"></textarea>

You can use the runat=server attribute with any standard HTML element, and later use it from codebehind.

forEach() :

return value : undefined

originalArray : not modified after the method call

newArray is not created after the end of method call.

map() :

return value : new Array populated with the results of calling a provided function on every element in the calling array

originalArray : not modified after the method call

newArray is created after the end of method call.

Since map builds a new array, using it when you aren't using the
returned array is an anti-pattern; use forEach or for-of instead.

An alternative solution could be using the following code DRandom. This class should be used with a seed. It provides a familiar interface to what you would expect in .NET, it was ported from mono's Random.cs. This code may not be cryptography safe and has not been statistically tested.

Just delete your .metadata folder in your workspace and start eclipse....:)

    OR description LIKE '%keyword%'
    OR refno LIKE '%keyword%';

I was looking for the same but couldn't find it, so I make a small script in PHP, you can find it at: http://tequilaphp.wordpress.com/2010/07/05/searching-strings-in-a-database-and-files/

Good luck! (I remove some private code, let me know if I didn't break it in the process :D)

First I think you need to fix your lists, as the first node of a <ul> must be a <li> (stackoverflow ref). Once that is setup you can do this:

// note this array has outer scope
var phrases = [];

$('.phrase').each(function(){
        // this is inner scope, in reference to the .phrase element
        var phrase = '';
        $(this).find('li').each(function(){
            // cache jquery var
            var current = $(this);
            // check if our current li has children (sub elements)
            // if it does, skip it
            // ps, you can work with this by seeing if the first child
            // is a UL with blank inside and odd your custom BLANK text
            if(current.children().size() > 0) {return true;}
            // add current text to our current phrase
            phrase += current.text();
        });
        // now that our current phrase is completely build we add it to our outer array
        phrases.push(phrase);
    });
    // note the comma in the alert shows separate phrases
    alert(phrases);

Working jsfiddle.

One thing is if you get the .text() of an upper level li you will get all sub level text with it.

Keeping an array will allow for many multiple phrases to be extracted.

EDIT:

This should work better with an empty UL with no LI:

// outer scope
var phrases = [];

$('.phrase').each(function(){

    var phrase = '';
    $(this).find('li').each(function(){
        // cache jquery object
        var current = $(this);
        // check for sub levels
        if(current.children().size() > 0) {
            // check is sublevel is just empty UL
            var emptyULtest = current.children().eq(0); 
            if(emptyULtest.is('ul') && $.trim(emptyULtest.text())==""){
                phrase += ' -BLANK- '; //custom blank text
                return true;   
            } else {
             // else it is an actual sublevel with li's
             return true;   
            }
        }
        // if it gets to here it is actual li
        phrase += current.text();
    });
    phrases.push(phrase);
});
// note the comma to separate multiple phrases
alert(phrases);

It's checking the return value ($?) of grep. In this case it's comparing it to 0 (success).

Usually when you see something like this (checking the return value of grep) it's checking to see whether the particular string was detected. Although the redirect to /dev/null isn't necessary, the same thing can be accomplished using -q.

Use array_values(array_unique($array));

array_unique: for unique array array_values: for reindexing

You could do something like this:

#youritem .fade.in {
    animation-name: fadeIn;
}

#youritem .fade.out {
    animation-name: fadeOut;
}

@keyframes fadeIn {
    0% {
        opacity: 0;
        transform: translateY(startYposition);
    } 
    100% {
        opacity: 1;
        transform: translateY(endYposition);
    }
}

@keyframes fadeOut {
    0% {
        opacity: 1;
        transform: translateY(startYposition);
    } 
    100% {
        opacity: 0;
        transform: translateY(endYposition);
    }
}

Example - Slide and Fade:

This slides and animates the opacity - not based on height of the container, but on the top/coordinate. View example

Example - Auto-height/No Javascript: Here is a live sample, not needing height - dealing with automatic height and no javascript.

A __pycache__ folder is created when you use the line:

import file_name

or try to get information from another file you have created. This makes it a little faster when running your program the second time to open the other file.

I think we have multiple solutions here:

• instance of could be a solution.

Why? In Java every class is inherited from the Object class itself. So if you have a variable and you would like to know its type. You can use

• System.out.println(((Object)f).getClass().getName());

or

• Integer.class.isInstance(1985); // gives true

or

• isPrimitive()

  public static void main(String[] args) {
  
   ClassDemo classOne = new ClassDemo();
   Class classOneClass = classOne();
  
   int i = 5;
   Class iClass = int.class;
  
   // checking for primitive type
   boolean retval1 = classOneClass.isPrimitive();
   System.out.println("classOneClass is primitive type? = " + retval1);
  
   // checking for primitive type?
   boolean retval2 = iClass.isPrimitive();
   System.out.println("iClass is primitive type? = " + retval2);
  }
  

This going to give us:

1. FALSE
2. TRUE

Find out more here: How to determine the primitive type of a primitive variable?

https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

http://docs.oracle.com/cd/E26806_01/wlp.1034/e14255/com/bea/p13n/expression/operator/Instanceof.html

Simple is that:

IF OBJECT_ID(dbo.TableName, 'U') IS NOT NULL
DROP TABLE dbo.TableName

where dbo.TableName is your desired table and 'U' is type of your table.

Although it doesn't apply to this specific example, Option 1 allows you to initialize member variables of reference type (or const type, as pointed out below). Option 2 doesn't. In general, Option 1 is the more powerful approach.

If you have Exchange 2010:

(In my case, the error message didn't contain " for [email protected]")

This shows how to add a receive connector: http://exchangeserverpro.com/how-to-configure-a-relay-connector-for-exchange-server-2010/

But I also needed to perform a step found here: http://recover-email.blogspot.com.au/2013/12/how-to-solve-exchange-smtp-server-error.html

• Go to Exchange Management Shell and run the command
• Get-ReceiveConnector "JiraTest" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"

While working on this, I ran the following on the affected server's PowerShell console until the error went away:

Send-MailMessage -From "[email protected]" -To "[email protected]" -Subject "Test Email" -Body "This is a test"

As jackrabb1t pointed out, --follow is more robust since it continues listing the history beyond renames/moves. So, if you are looking for a file that is not currently in the same path or a file that has been renamed throughout various commits, --follow will track it.

This can be a better option if you want to visualize the name/path changes:

git log --follow --name-status -- <path>

But if you want a more compact list with only what matters:

git log --follow --name-status --format='%H' -- <path>

or even

git log --follow --name-only --format='%H' -- <path>

The downside is that --follow only works for a single file.

Sun's java 1.4 has the following arguments to control memory size:

-Xmsn Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB. Examples:

           -Xms6291456
           -Xms6144k
           -Xms6m

-Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:

           -Xmx83886080
           -Xmx81920k
           -Xmx80m

http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/java.html

Java 5 and 6 have some more. See http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp

you can try typescript's For :

selectChildren(data , $event){
   let parentChecked : boolean = data.checked;
   for(let o of this.hierarchicalData){
      for(let child of o){
         child.checked = parentChecked;
      }
   }
}

I had the similar issue, unfortunately I used the GitExtensions HMI and forgot that I wrote a passphrase. With HMI.... forget it ! Do not enter passphrase when you generate your key !

BOTHER appears to be available from <asm/termios.h> on Linux. Pulling the definition from there is going to be wildly non-portable, but I assume this API is non-portable anyway, so it's probably no big loss.

ind_list = [1, 3]
df.ix[ind_list]

should do the trick! When I index with data frames I always use the .ix() method. Its so much easier and more flexible...

UPDATE This is no longer the accepted method for indexing. The ix method is deprecated. Use .iloc for integer based indexing and .loc for label based indexing.

Passing data from one Activity to Activity in android

An intent contains the action and optionally additional data. The data can be passed to other activity using intent putExtra() method. Data is passed as extras and are key/value pairs. The key is always a String. As value you can use the primitive data types int, float, chars, etc. We can also pass Parceable and Serializable objects from one activity to other.

Intent intent = new Intent(context, YourActivity.class);
intent.putExtra(KEY, <your value here>);
startActivity(intent);

Retrieving bundle data from android activity

You can retrieve the information using getData() methods on the Intent object. The Intent object can be retrieved via the getIntent() method.

 Intent intent = getIntent();
  if (null != intent) { //Null Checking
    String StrData= intent.getStringExtra(KEY);
    int NoOfData = intent.getIntExtra(KEY, defaultValue);
    boolean booleanData = intent.getBooleanExtra(KEY, defaultValue);
    char charData = intent.getCharExtra(KEY, defaultValue); 
  }

import java.io.*;
import java.util.Scanner;
class ar1 {
    public static void main(String[] args) {
        //Scanner sc=new Scanner(System.in);
        int[] a={10,20,30,40,12,32};
        int bi=0,sm=0;
        //bi=sc.nextInt();
        //sm=sc.nextInt();
        for(int i=0;i<=a.length-1;i++) {
            if(a[i]>a[i+1]) 
                bi=a[i];

            if(a[i]<a[i+1])
                sm=a[i];
        }
        System.out.println("big"+bi+"small"+sm);
    }
}

You cannot use items instead iteritems in all places in Python. For example, the following code:

class C:
  def __init__(self, a):
    self.a = a
  def __iter__(self):
    return self.a.iteritems()

>>> c = C(dict(a=1, b=2, c=3))
>>> [v for v in c]
[('a', 1), ('c', 3), ('b', 2)]

will break if you use items:

class D:
  def __init__(self, a):
    self.a = a
  def __iter__(self):
    return self.a.items()

>>> d = D(dict(a=1, b=2, c=3))
>>> [v for v in d]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __iter__ returned non-iterator of type 'list'

The same is true for viewitems, which is available in Python 3.

Also, since items returns a copy of the dictionary’s list of (key, value) pairs, it is less efficient, unless you want to create a copy anyway.

In Python 2, it is best to use iteritems for iteration. The 2to3 tool can replace it with items if you ever decide to upgrade to Python 3.

You can also use Comparator.comparing(Function, Comparator)
It is convenient to chain comparators when necessary, e.g.:

Comparator<SomeEntity> ENTITY_COMPARATOR = comparing(SomeEntity::getProperty1, reverseOrder())
        .thenComparingInt(SomeEntity::getProperty2)
        .thenComparing(SomeEntity::getProperty3, reverseOrder());

use this code it is working

You are trying to create a wrapper to get Application Context and there is a possibility that it might return "null" pointer.

As per my understanding, I guess its better approach to call- any of the 2 Context.getApplicationContext() or Activity.getApplication().

You can use the following code to copy files from one directory to another

// parent folders of dest must exist before calling this function
public static void copyTo( File src, File dest ) throws IOException {
     // recursively copy all the files of src folder if src is a directory
     if( src.isDirectory() ) {
         // creating parent folders where source files is to be copied
         dest.mkdirs();
         for( File sourceChild : src.listFiles() ) {
             File destChild = new File( dest, sourceChild.getName() );
             copyTo( sourceChild, destChild );
         }
     } 
     // copy the source file
     else {
         InputStream in = new FileInputStream( src );
         OutputStream out = new FileOutputStream( dest );
         writeThrough( in, out );
         in.close();
         out.close();
     }
 }

Vanilla:

window.addEventListener('scroll', function(ev) {

   var someDiv = document.getElementById('someDiv');
   var distanceToTop = someDiv.getBoundingClientRect().top;

   console.log(distanceToTop);
});

Open your browser console and scroll your page to see the distance.

In array you also can use variables passing to req.params:

app.get(["/:foo", "/:foo/:bar"], /* function */);

The problem is in the import line. You are importing a module, not a class. Assuming your file is named other_file.py (unlike java, again, there is no such rule as "one class, one file"):

from other_file import findTheRange

if your file is named findTheRange too, following java's convenions, then you should write

from findTheRange import findTheRange

you can also import it just like you did with random:

import findTheRange
operator = findTheRange.findTheRange()

Some other comments:

a) @Daniel Roseman is right. You do not need classes here at all. Python encourages procedural programming (when it fits, of course)

b) You can build the list directly:

  randomList = [random.randint(0, 100) for i in range(5)]

c) You can call methods in the same way you do in java:

largestInList = operator.findLargest(randomList)
smallestInList = operator.findSmallest(randomList)

d) You can use built in function, and the huge python library:

largestInList = max(randomList)
smallestInList = min(randomList)

e) If you still want to use a class, and you don't need self, you can use @staticmethod:

class findTheRange():
    @staticmethod
    def findLargest(_list):
        #stuff...

You can do something like this

Session session = app.factory.openSession();
CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery query = builder.createQuery();
Root<Users> root = query.from(Users.class);
query.select(root.get("firstname"));
String name = session.createQuery(query).getSingleResult();

where you can change "firstname" with the name of the column you want.

It's producing enumerable sequence. What it does is actually creating local IEnumerable sequence and returning it as a method result

No need to find. If you are just looking for a pattern within a specific directory, this should suffice:

grep -hn FOO /your/path/*.bar

Where -h is the parameter to hide the filename, as from man grep:

-h, --no-filename

Suppress the prefixing of file names on output. This is the default when there is only one file (or only standard input) to search.

Note that you were using

-H, --with-filename

Print the file name for each match. This is the default when there is more than one file to search.

If you are looking for the last row of a column, use:

Sub SelectFirstColumn()
   SelectEntireColumn (1)
End Sub

Sub SelectSecondColumn()
    SelectEntireColumn (2)
End Sub

Sub SelectEntireColumn(columnNumber)
    Dim LastRow
    Sheets("sheet1").Select
    LastRow = ActiveSheet.Columns(columnNumber).SpecialCells(xlLastCell).Row

    ActiveSheet.Range(Cells(1, columnNumber), Cells(LastRow, columnNumber)).Select
End Sub

Other commands you will need to get familiar with are copy and paste commands:

Sub CopyOneToTwo()
    SelectEntireColumn (1)
    Selection.Copy

    Sheets("sheet1").Select
    ActiveSheet.Range("B1").PasteSpecial Paste:=xlPasteValues
End Sub

Finally, you can reference worksheets in other workbooks by using the following syntax:

Dim book2
Set book2 = Workbooks.Open("C:\book2.xls")
book2.Worksheets("sheet1")

The path of the cache directory is listed in the About window (menu Help/About). Close NetBeans, then delete (or rename) the directory. NetBeans will rebuild its cache when it starts up.

One way would be to first flatten the list with a SelectMany:

subList.SelectMany(m => m).Where(k => k.Key.Equals("valueTitle"));

I'd answer this question with another question: Do you use singeltons/ Are singeltons bad?

Because (almost all) singelton usage is a glorified global variable.

If you have to consider the Windows case in order to be cross-platform, then try the following:

os.system('taskkill /f /im exampleProcess.exe')

Here is the plunker

New plunker with cleaner code & where both the query and search list items are case insensitive

Main idea is create a filter function to achieve this purpose.

From official doc

function: A predicate function can be used to write arbitrary filters. The function is called for each element of array. The final result is an array of those elements that the predicate returned true for.

<input ng-model="query">

<tr ng-repeat="smartphone in smartphones | filter: search "> 

$scope.search = function(item) {
    if (!$scope.query || (item.brand.toLowerCase().indexOf($scope.query) != -1) || (item.model.toLowerCase().indexOf($scope.query.toLowerCase()) != -1) ){
        return true;
    }
    return false;
};

Update

Some people might have a concern on performance in real world, which is correct.

In real world, we probably would do this kinda filter from controller.

Here is the detail post showing how to do it.

in short, we add ng-change to input for monitoring new search change

and then trigger filter function.

The following one-liner fast-forwards all branches that have an upstream branch if possible, and prints an error otherwise:

git branch \
  --format "%(if)%(upstream:short)%(then)git push . %(upstream:short):%(refname:short)%(end)" |
  sh

How does it work?

It uses a custom format with the git branch command. For each branch that has an upstream branch, it prints a line with the following pattern:

git push . <remote-ref>:<branch>

This can be piped directly into sh (assuming that the branch names are well-formed). Omit the | sh to see what it's doing.

Caveats

The one-liner will not contact your remotes. Issue a git fetch or git fetch --all before running it.

The currently checked-out branch will not be updated with a message like

! [remote rejected] origin/master -> master (branch is currently checked out)

For this, you can resort to regular git pull --ff-only .

Alias

Add the following to your .gitconfig so that git fft performs this command:

[alias]
        fft = !sh -c 'git branch --format \"%(if)%(upstream:short)%(then)git push . %(upstream:short):%(refname:short)%(end)\" | sh' -

See also my .gitconfig. The alias is a shorthand to "fast-forward tracking (branches)".

I think you can try this for calling in from a class

 System.Web.HttpContext.Current.Server.MapPath("~/SignatureImages/");

*----------------Sorry I oversight, for static function already answered the question by adrift*

System.Web.Hosting.HostingEnvironment.MapPath("~/SignatureImages/");

Update

I got exception while using System.Web.Hosting.HostingEnvironment.MapPath("~/SignatureImages/");

Ex details : System.ArgumentException: The relative virtual path 'SignatureImages' is not allowed here. at System.Web.VirtualPath.FailIfRelativePath()

Solution (tested in static webmethod)

System.Web.HttpContext.Current.Server.MapPath("~/SignatureImages/"); Worked

 a = [[a, 2], [b, 3], [c, 4], [d, 5], [a, 1], [b, 6], [e, 7], [h, 8]]

I need this from above one

 a = [[a, 3], [b, 9], [c, 4], [d, 5], [e, 7], [h, 8]]

a.append([0, 0])
for i in range(len(a)):
     for j in range(i + 1, len(a) - 1):
            if a[i][0] == a[j][0]:
                    a[i][1] += a[j][1]
                    del a[j]
a.pop()
        

To find the minimum value of a list, you might just as well use min:

x = min(float(s) for s in l) # min of a generator

Or, if you want the result as a string, rather than a float, use a key function:

x = min(l, key=float)

Probably the project you are running is not compatible (API version/Hardware requirements) with the emulator settings. Check in your build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.

You should also uncheck Tools > Android > Enable ADB Integration

If your case is different then restart your Android Studio and run the emulator again.

I've just found out this little trick for testing if exception names in Python 2.7 . Sometimes i have handled specific exceptions in the code, so i needed a test to see if that name is within a list of handled exceptions.

try:
    raise IndexError #as test error
except Exception as e:
    excepName = type(e).__name__ # returns the name of the exception

One way is to use a script tag to import the variables you want to your views:

<script type="text/javascript">
window.base_url = <?php echo json_encode(base_url()); ?>;
</script>

Here, I wrapped the base_url with json_encode so that it'll automatically escape any characters to valid Javascript. I put base_url to the global Window so you can use it anywhere just by calling base_url, but make sure to put the script tag above any Javascript that calls it. With your given example:

...
$('#style_color').attr("href", base_url + "assets/css/themes/" + color_ + ".css");

Additional to the above - the QEMU website has good documentation about setting up an ARM based emulator: http://qemu.weilnetz.de/qemu-doc.html#ARM-System-emulator

The following is slower than the approaches timed here, but we can compute the extra column based on the contents of more than one column, and more than two values can be computed for the extra column.

Simple example using just the "Set" column:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Example with more colours and more columns taken into account:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    elif row["Type"] == "C":
        return "blue"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C   blue

Edit (21/06/2019): Using plydata

It is also possible to use plydata to do this kind of things (this seems even slower than using assign and apply, though).

from plydata import define, if_else

Simple if_else:

df = define(df, color=if_else('Set=="Z"', '"red"', '"green"'))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Nested if_else:

df = define(df, color=if_else(
    'Set=="Z"',
    '"red"',
    if_else('Type=="C"', '"green"', '"blue"')))

print(df)                            

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B   blue
3   Y    C  green

Here is a working example:

@echo off
:ask
@echo echo Would you like to use developer mode?(Y/N)
set INPUT=
set /P INPUT=Type input: %=%
If /I "%INPUT%"=="y" goto yes 
If /I "%INPUT%"=="n" goto no
goto ask
:yes
@echo you select yes
goto exit
:no
@echo you select no
goto exit
:exit
@pause

When your certificate expires, it simply disappears from the ‘Certificates, Identifier & Profiles’ section of Member Center. There is no ‘Renew’ button that allows you to renew your certificate. You can revoke a certificate and generate a new one before it expires. Or you can wait for it to expire and disappear, then generate a new certificate. In Apple's App Distribution Guide:

Replacing Expired Certificates

When your development or distribution certificate expires, remove it and request a new certificate in Xcode.

When your certificate expires or is revoked, any provisioning profile that made use of the expired/revoked certificate will be reflected as ‘Invalid’. You cannot build and sign any app using these invalid provisioning profiles. As you can imagine, I'd rather revoke and regenerate a certificate before it expires.

Q: If I do that then will all my live apps be taken down?

Apps that are already on the App Store continue to function fine. Again, in Apple's App Distribution Guide:

Important: Re-creating your development or distribution certificates doesn’t affect apps that you’ve submitted to the store nor does it affect your ability to update them.

So…

Q: How to I properly renew it?

As mentioned above, there is no renewing of certificates. Follow the steps below to revoke and regenerate a new certificate, along with the affected provisioning profiles. The instructions have been updated for Xcode 8.3 and Xcode 9.

Step 1: Revoke the expiring certificate

Login to Member Center > Certificates, Identifiers & Profiles, select the expiring certificate. Take note of the expiry date of the certificate, and click the ‘Revoke’ button.

Step 2: (Optional) Remove the revoked certificate from your Keychain

Optionally, if you don't want to have the revoked certificate lying around in your system, you can delete them from your system. Unfortunately, the ‘Delete Certificate’ function in Xcode > Preferences > Accounts > [Apple ID] > Manage Certificates… seems to be always disabled, so we have to delete them manually using Keychain Access.app (/Applications/Utilities/Keychain Access.app).

Filter by ‘login’ Keychains and ‘Certificates’ Category. Locate the certificate that you've just revoked in Step 1.

Depending on the certificate that you've just revoked, search for either ‘Mac’ or ‘iPhone’. Mac App Store distribution certificates begin with “3rd Party Mac Developer”, and iOS App Store distribution certificates begin with “iPhone Distribution”.

You can locate the revoked certificate based on the team name, the type of certificate (Mac or iOS) and the expiry date of the certificate you've noted down in Step 1.

Step 3: Request a new certificate using Xcode

Under Xcode > Preferences > Accounts > [Apple ID] > Manage Certificates…, click on the ‘+’ button on the lower left, and select the same type of certificate that you've just revoked to let Xcode request a new one for you.

Step 4: Update your provisioning profiles to use the new certificate

After which, head back to Member Center > Certificates, Identifiers & Profiles > Provisioning Profiles > All. You'll notice that any provisioning profile that made use of the revoked certificate is now reflected as ‘Invalid’.

Click on any profile that are now ‘Invalid’, click ‘Edit’, then choose the newly created certificate, then click on ‘Generate’. Repeat this until all provisioning profiles are regenerated with the new certificate.

Step 5: Use Xcode to download the new provisioning profiles

Tip: Before you download the new profiles using Xcode, you may want to clear any existing and possibly invalid provisioning profiles from your Mac. You can do so by removing all the profiles from ~/Library/MobileDevice/Provisioning Profiles

Back in Xcode > Preferences > Accounts > [Apple ID], click on the ‘Download All Profiles’ button to ask Xcode to download all the provisioning profiles from your developer account.

It turns out that there is a float: left property by default on all navbar-nav>li elements, which is why they were all scrunching up to the left. Once I added the code below, it made the navbar both centered and not scrunched up.

.navbar-nav>li {
        float: none;
}

Hope this helps someone else who's looking to center a navbar.

var fs = require('fs');

function base64Encode(file) {
    var body = fs.readFileSync(file);
    return body.toString('base64');
}


var base64String = base64Encode('test.jpg');
console.log(base64String);

Immutable, suitable for ReactJS:

Assume:

cosnt arr = [{id: 1, name: "Person 1"}, {id:2, name:"Person 2"}];

The updated item is the second and name is changed to Special Person:

const updatedItem = {id:2, name:"Special Person"};

Hint: the lodash has useful tools but now we have some of them on Ecmascript6+, so I just use map function that is existed on both of lodash and ecmascript6+:

const newArr = arr.map(item => item.id === 2 ? updatedItem : item);

the method modify() that you called in the last is called in global context if you want to override modify() you first have to inherit A or B.

Maybe you're trying to do this:

In this case C inherits A

function A() {
    this.modify = function() {
        alert("in A");
    }
}

function B() {
    this.modify = function() {
        alert("in B");
    }
}

C = function() {
    this.modify = function() {
        alert("in C");
    };

    C.prototype.modify(); // you can call this method where you need to call modify of the parent class
}

C.prototype = new A();

You can do the following steps:

1. First isolate the column (by inserting a blank column before and/or after the column you want to count the unique values if there are any adjacent columns;

2. Then select the whole column, go to 'Data' > 'Advanced Filter' and check the checkbox 'Unique records only'. This will hide all non-unique records so you can count the unique ones by selecting the whole column.

This is apparently a bug in the Entity Framework that the model does not get updated when your Edmx file is located inside a folder. The workarounds available at the moment are:

1. Install VS 2012 Update 1 which should fix the bug.
2. If you are not in a position to install Update 1, you will have to right click on the model.tt T4 template file and click run custom tool. This will update the classes for you.

Hope that helps someone out there.

In Ruby 1.9.2 and above they added a .to_date function to DateTime:

http://ruby-doc.org/stdlib-1.9.2/libdoc/date/rdoc/DateTime.html#method-i-to_date

This instance method doesn't appear to be present in earlier versions like 1.8.7.

In Ruby, any variable whose name starts with a capital letter is a constant and you can only assign to it once. Choose one of these alternatives:

class MyClass
  MYCONSTANT = "blah"

  def mymethod
    MYCONSTANT
  end
end

class MyClass
  def mymethod
    my_constant = "blah"
  end
end

Use display instead of visibility. display: none for invisible and no setting for visible.

Simply put, the transient java keyword protect fields from the been Serialize as their non-transient fields counter parts.

In this code snippet our abstract class BaseJob implement Serializable interface, we extends from BaseJob but we need not serialize the remote and local data sources; serialize only organizationName and isSynced fields.

public abstract class BaseJob implements Serializable{
   public void ShouldRetryRun(){}
}

public class SyncOrganizationJob extends BaseJob {

   public String organizationName;
   public Boolean isSynced

   @Inject transient RemoteDataSource remoteDataSource;
   @Inject transient LocalDaoSource localDataSource;

   public SyncOrganizationJob(String organizationName) {
     super(new 
         Params(BACKGROUND).groupBy(GROUP).requireNetwork().persist());

      this.organizationName = organizationName;
      this.isSynced=isSynced;

   }
}

Swift 4.2 solution that takes possible heights of UIToolbar and UITabBar into account.

private func setupKeyboardNotifications() {
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIControl.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIControl.keyboardWillHideNotification, object: nil)
}

@objc func keyboardWillShow(_ notification: Notification) {
    let userInfo: NSDictionary = notification.userInfo! as NSDictionary
    let keyboardSize = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue.size

    let tabbarHeight = tabBarController?.tabBar.frame.size.height ?? 0
    let toolbarHeight = navigationController?.toolbar.frame.size.height ?? 0
    let bottomInset = keyboardSize.height - tabbarHeight - toolbarHeight

    scrollView.contentInset.bottom = bottomInset
    scrollView.scrollIndicatorInsets.bottom = bottomInset
}

@objc func keyboardWillHide(_ notification: Notification) {
    scrollView.contentInset = .zero
    scrollView.scrollIndicatorInsets = .zero
}

And, if you're targeting < iOS 9, you have to unregister the observer at some point (thanks Joe)

The return statement stops a loop only if it's inside the function (i.e. it terminates both the loop and the function). Otherwise, you will get this error:

Uncaught SyntaxError: Illegal return statement(…)

To terminate a loop you should use break.

You can't: DataFrame columns are Series, by definition. That said, if you make the dtype (the type of all the elements) datetime-like, then you can access the quantities you want via the .dt accessor (docs):

>>> df["TimeReviewed"] = pd.to_datetime(df["TimeReviewed"])
>>> df["TimeReviewed"]
205  76032930   2015-01-24 00:05:27.513000
232  76032930   2015-01-24 00:06:46.703000
233  76032930   2015-01-24 00:06:56.707000
413  76032930   2015-01-24 00:14:24.957000
565  76032930   2015-01-24 00:23:07.220000
Name: TimeReviewed, dtype: datetime64[ns]
>>> df["TimeReviewed"].dt
<pandas.tseries.common.DatetimeProperties object at 0xb10da60c>
>>> df["TimeReviewed"].dt.year
205  76032930    2015
232  76032930    2015
233  76032930    2015
413  76032930    2015
565  76032930    2015
dtype: int64
>>> df["TimeReviewed"].dt.month
205  76032930    1
232  76032930    1
233  76032930    1
413  76032930    1
565  76032930    1
dtype: int64
>>> df["TimeReviewed"].dt.minute
205  76032930     5
232  76032930     6
233  76032930     6
413  76032930    14
565  76032930    23
dtype: int64

If you're stuck using an older version of pandas, you can always access the various elements manually (again, after converting it to a datetime-dtyped Series). It'll be slower, but sometimes that isn't an issue:

>>> df["TimeReviewed"].apply(lambda x: x.year)
205  76032930    2015
232  76032930    2015
233  76032930    2015
413  76032930    2015
565  76032930    2015
Name: TimeReviewed, dtype: int64

For people wondering, this also works for button click. For example:

private void btn_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Test")
        }

private void txb_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)13)
            {
                btn_Click(sender, e);
            }

When pressing Enter in the textfield(txb) in this case it will click the button which will active the MessageBox.

If you can change the format of your placeholder, you could use String.format(). If not, you could also replace it as pre-processing.

String.format("hello %s!", "world");

From Microsoft MSDN recommendations:

Application icons and Control Panel items: The full set includes 16x16, 32x32, 48x48, and 256x256 (code scales between 32 and 256). The .ico file format is required. For Classic Mode, the full set is 16x16, 24x24, 32x32, 48x48 and 64x64.

So we have already standard recommended sizes of:

• 16 x 16,
• 24 x 24,
• 32 x 32,
• 48 x 48,
• 64 x 64,
• 256 x 256.

If we would like to support high DPI settings, the complete list will include the following sizes as well:

• 20 x 20,
• 30 x 30,
• 36 x 36,
• 40 x 40,
• 60 x 60,
• 72 x 72,
• 80 x 80,
• 96 x 96,
• 128 x 128,
• 320 x 320,
• 384 x 384,
• 512 x 512.

Use Element#outerHTML:

var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));

console.log(el.outerHTML);

It can also be used to write DOM elements. From Mozilla's documentation:

The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. It can be set to replace the element with nodes parsed from the given string.

I had same issue with VMWare 12.5.2 and OS: Mac OS Sierra.
These are few steps to solve this issue:(which worked for me.)

1. Open VMWare.
2. select your OS. (Mine is MacOS Sierra)
3. Then In left hand side, Select option "Edit virtual machine settings"
4. There will be one popup of setting. In that you need to select "Hardware" Tab.
5. In that, there is option "USB Controller". Select that. You will find option right hand side.
6. In that, Set USB compatibility as "USB 2.0" and check all 3 options as selected. options must be as following: i) Automatically connect new USB devices, ii) Show all USB input devices, iii) Share Bluetooth devices with the virtual machine
7. Press OK.

There you go. It will work. Now you can power on your virtual machine.And try to connect your device with proper USB cable. Sometimes there can be issue with USB cable which are not authorized. Still if you have doubt, you can ask me here.

Just put below code in AndroidManifest :

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

Update for Twig 2 and Twig 3.

truncate filter is not available, instead of it you may use u-filter

here is an example:

{{ 'Lorem ipsum'|u.truncate(8) }}
Lorem ip

{{ 'Lorem ipsum'|u.truncate(8, '...') }}
Lorem...

Note: this filter is part of StringExtension that can be required by

twig/string-extra

Do you know View.getViewTreeObserver().addOnGlobalLayoutListener()

By this you can calculate the sizes.

I achieve your UI effect by GridView:

GridView g;
g.setNumColumns(2);
g.setStretchMode(GridView.STRETCH_SPACING_UNIFORM);

It's because you're calling doGet() without actually implementing doGet(). It's the default implementation of doGet() that throws the error saying the method is not supported.

This has been discussed in many posts but still I could not figure out a solution with:

android:focusable="false"
android:focusableInTouchMode="false"
android:focusableInTouchMode="false"

Below solution will work with any of the ui components : Button, ImageButtons, ImageView, Textview. LinearLayout, RelativeLayout clicks inside a listview cell and also will respond to onItemClick:

Adapter class - getview():

    @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view = convertView;
            if (view == null) {
                view = lInflater.inflate(R.layout.my_ref_row, parent, false);
            }
            final Organization currentOrg = organizationlist.get(position).getOrganization();

            TextView name = (TextView) view.findViewById(R.id.name);
            Button btn = (Button) view.findViewById(R.id.btn_check);
            btn.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    context.doSelection(currentOrg);

                }
            });

       if(currentOrg.isSelected()){
            btn.setBackgroundResource(R.drawable.sub_search_tick);
        }else{
            btn.setBackgroundResource(R.drawable.sub_search_tick_box);
        }

    }

In this was you can get the button clicked object to the activity. (Specially when you want the button to act as a check box with selected and non-selected states):

    public void doSelection(Organization currentOrg) {
        Log.e("Btn clicked ", currentOrg.getOrgName());
        if (currentOrg.isSelected() == false) {
            currentOrg.setSelected(true);
        } else {
            currentOrg.setSelected(false);
        }
        adapter.notifyDataSetChanged();

    }

By design there is no simple way to turn on or turn off the identity feature for an existing column. The only clean way to do this is to create a new column and make it an identity column or create a new table and migrate your data.

If we use SQL Server Management Studio to get rid of the identity value on column "id", a new temporary table is created, the data is moved to the temporary table, the old table is dropped and the new table is renamed.

Use Management Studio to make the change and then right click in the designer and select "Generate Change Script".

You will see that this is what SQL server in doing in the background.

There is also the possibility to use the Vector Asset Studio in combination with Scalable Vector Graphics (SVG). Android Studio will handle the rest for you. As the official documentation says:

Vector Asset Studio helps you add material icons and import Scalable Vector Graphic (SVG) files into your app project as a drawable resource. Compared to raster images, vector drawables can reduce the size of your app and be resized without loss of image quality. They help you to more easily support different Android devices with varying screen sizes and resolutions because you can display one vector drawable on all of them.

I consider this the future approach.

Use dict.setdefault():

dic.setdefault(key,[]).append(value)

help(dict.setdefault):

    setdefault(...)
        D.setdefault(k[,d]) -> D.get(k,d), also set D[k]=d if k not in D

In your particular case the fastest sort is probably the one described in this answer. It is exactly optimized for an array of 6 ints and uses sorting networks. It is 20 times (measured on x86) faster than library qsort. Sorting networks are optimal for sort of fixed length arrays. As they are a fixed sequence of instructions they can even be implemented easily by hardware.

Generally speaking there is many sorting algorithms optimized for some specialized case. The general purpose algorithms like heap sort or quick sort are optimized for in place sorting of an array of items. They yield a complexity of O(n.log(n)), n being the number of items to sort.

The library function qsort() is very well coded and efficient in terms of complexity, but uses a call to some comparizon function provided by user, and this call has a quite high cost.

For sorting very large amount of datas algorithms have also to take care of swapping of data to and from disk, this is the kind of sorts implemented in databases and your best bet if you have such needs is to put datas in some database and use the built in sort.

Streams don't have a simple .toString() function (which I understand) nor something like a .toStringAsync(cb) function (which I don't understand).

So I created my own helper function:

var streamToString = function(stream, callback) {
  var str = '';
  stream.on('data', function(chunk) {
    str += chunk;
  });
  stream.on('end', function() {
    callback(str);
  });
}

// how to use:
streamToString(myStream, function(myStr) {
  console.log(myStr);
});

Sorting is a secondary problem here. As other said, just storing the integers is hard, and cannot work on all inputs, since 27 bits per number would be necessary.

My take on this is: store only the differences between the consecutive (sorted) integers, as they will be most likely small. Then use a compression scheme, e.g. with 2 additional bits per input number, to encode how many bits the number is stored on. Something like:

00 -> 5 bits
01 -> 11 bits
10 -> 19 bits
11 -> 27 bits

It should be possible to store a fair number of possible input lists within the given memory constraint. The maths of how to pick the compression scheme to have it work on the maximum number of inputs, are beyond me.

I hope you may be able to exploit domain-specific knowledge of your input to find a good enough integer compression scheme based on this.

Oh and then, you do an insertion sort on that sorted list as you receive data.

Try this code,

public void ConnectToAccess()

    System.Data.OleDb.OleDbConnection conn = new 
        System.Data.OleDb.OleDbConnection();

    conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
        @"Data source= C:\Documents and Settings\username\" +
        @"My Documents\AccessFile.mdb";
    try
    {
        conn.Open();
        // Insert code to process data.
    }

There is no difference ...

So principially you could use both (one at a time !-)

But for the sake of readability and for the cleanliness of the html-code I always prefer the window.onload !o]

To properly answer this qustion you need to consider PHP internals or the target that PHP is built for.

To answer this from a typical Linux perspective on x86...

Sizes of types in C: https://usrmisc.wordpress.com/2012/12/27/integer-sizes-in-c-on-32-bit-and-64-bit-linux/

Types used in PHP for variables: http://php.net/manual/en/internals2.variables.intro.php

Strings are always 2GB as the length is always 32bits and a bit is wasted because it uses int rather than uint. int is impractical for lengths over 2GB as it requires a cast to avoid breaking arithmetic or "than" comparisons. The extra bit is likely being used for overflow checks.

Strangely, hash keys might internally support 4GB as uint is used although I have never put this to the test. PHP hash keys have a +1 to the length for a trailing null byte which to my knowledge gets ignored so it may need to be unsigned for that edge case rather than to allow longer keys.

A 32bit system may impose more external limits.

Use this in web.config:

<sessionState 

  timeout="20" 
/>

Move the srand call to the start of the program. As you have it now, the time might be the same between two consecutive calls, so the random number generator will start again at the same spot.

You have to catch the error just as you're already doing for your save() call and since you're handling multiple errors here, you can try multiple calls sequentially in a single do-catch block, like so:

func deleteAccountDetail() {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()
    request.entity = entityDescription

    do {
        let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]

        for entity in fetchedEntities {
            self.Context!.deleteObject(entity)
        }

        try self.Context!.save()
    } catch {
        print(error)
    }
}

Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws then try to call the method. For example:

func deleteAccountDetail() throws {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()

    request.entity = entityDescription

    let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]

    for entity in fetchedEntities {
        self.Context!.deleteObject(entity)
    }

    try self.Context!.save()
}

For formatting options, see this

Dim v1 as Double = Val(txtD.Text) / Val(txtC.Text) *
                   Val(txtF.Text) / Val(txtE.Text)
txtA.text = v1.ToString("N2");

I'm here in general only to find out that through dict it is necessary to work inside setattr XD

I use Log.d method also please import import android.util.Log;

Log.d("TAG", "Message");

But please keep in mind that, when you want to see the debug messages then don't use Run As rather use "Debug As" then select Android Application. Otherwise you'll not see the debug messages.

try following command

remove node_modules and package-lock.json

rm -rf node_modules package-lock.json

then run following command to install dependencies

npm install

finally, run your package by following command.

npm start

In PowerShell, the "sc" command is an alias for the Set-Content cmdlet. You can workaround this using the following syntax:

sc.exe config Service obj= user password= pass

Specyfying the .exe extension, PowerShell bypasses the alias lookup.

The readarray command (also spelled mapfile) was introduced in bash 4.0.

-Xmn : the size of the heap for the young generation

Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor".

And a more "official" source from IBM:

-Xmn

Sets the initial and maximum size of the new (nursery) heap to the specified value when using -Xgcpolicy:gencon. Equivalent to setting both -Xmns and -Xmnx. If you set either -Xmns or -Xmnx, you cannot set -Xmn. If you attempt to set -Xmn with either -Xmns or -Xmnx, the VM will not start, returning an error. By default, -Xmn is selected internally according to your system's capability. You can use the -verbose:sizes option to find out the values that the VM is currently using.

Since this is the number one hit to the question: Read multi sheet excel to list:

here is the openxlsx solution:

filename <-"myFilePath"

sheets <- openxlsx::getSheetNames(filename)
SheetList <- lapply(sheets,openxlsx::read.xlsx,xlsxFile=filename)
names(SheetList) <- sheets

@Ahmed

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close

2018 Update

Now you can use just window.scrollTo({ top: 0, behavior: 'smooth' }) to get the page scrolled with a smooth effect.

const btn = document.getElementById('elem');_x000D_
_x000D_
btn.addEventListener('click', () => window.scrollTo({_x000D_
  top: 400,_x000D_
  behavior: 'smooth',_x000D_
}));

#x {_x000D_
  height: 1000px;_x000D_
  background: lightblue;_x000D_
}

<div id='x'>_x000D_
  <button id='elem'>Click to scroll</button>_x000D_
</div>

Older solutions

You can do something like this:

var btn = document.getElementById('x');_x000D_
_x000D_
btn.addEventListener("click", function() {_x000D_
  var i = 10;_x000D_
  var int = setInterval(function() {_x000D_
    window.scrollTo(0, i);_x000D_
    i += 10;_x000D_
    if (i >= 200) clearInterval(int);_x000D_
  }, 20);_x000D_
})

body {_x000D_
  background: #3a2613;_x000D_
  height: 600px;_x000D_
}

<button id='x'>click</button>

ES6 recursive approach:

const btn = document.getElementById('elem');_x000D_
_x000D_
const smoothScroll = (h) => {_x000D_
  let i = h || 0;_x000D_
  if (i < 200) {_x000D_
    setTimeout(() => {_x000D_
      window.scrollTo(0, i);_x000D_
      smoothScroll(i + 10);_x000D_
    }, 10);_x000D_
  }_x000D_
}_x000D_
_x000D_
btn.addEventListener('click', () => smoothScroll());

body {_x000D_
  background: #9a6432;_x000D_
  height: 600px;_x000D_
}

<button id='elem'>click</button>

I think that this is as easy as I can explain it. Please, anyone is welcome to correct me or add to this.

SOAP is a message format used by disconnected systems (like across the internet) to exchange information / data. It does with XML messages going back and forth.

Web services transmit or receive SOAP messages. They work differently depending on what language they are written in.

Php Implementation of Chris's C# Code

Also from here, which explains the math of it very well.

This is basically a bunch of functions to convert to and from HSL (Hue Saturation Lightness)

Tested and working on PHP 5.6.15

TL;DR: The full code can be found here on Pastebin.

Hex to HSL

As I said in comments - you should always use parameters in your query - NEVER EVER concatenate together your SQL statements yourself.

Also: I would recommend to separate the click event handler from the actual code to insert the data.

So I would rewrite your code to be something like

In your web page's code-behind file (yourpage.aspx.cs)

private void button1_Click(object sender, EventArgs e)
{
      string connectionString = "Data Source=DELL-PC;initial catalog=AdventureWorks2008R2 ; User ID=sa;Password=sqlpass;Integrated Security=SSPI;";

      InsertData(connectionString,
                 textBox1.Text.Trim(),  -- first name
                 textBox2.Text.Trim(),  -- last name
                 textBox3.Text.Trim(),  -- user name
                 textBox4.Text.Trim(),  -- password
                 Convert.ToInt32(comboBox1.Text),  -- age
                 comboBox2.Text.Trim(), -- gender
                 textBox7.Text.Trim() );  -- contact
}

In some other code (e.g. a databaselayer.cs):

private void InsertData(string connectionString, string firstName, string lastname, string username, string password
                        int Age, string gender, string contact)
{
    // define INSERT query with parameters
    string query = "INSERT INTO dbo.regist (FirstName, Lastname, Username, Password, Age, Gender,Contact) " + 
                   "VALUES (@FirstName, @Lastname, @Username, @Password, @Age, @Gender, @Contact) ";

    // create connection and command
    using(SqlConnection cn = new SqlConnection(connectionString))
    using(SqlCommand cmd = new SqlCommand(query, cn))
    {
        // define parameters and their values
        cmd.Parameters.Add("@FirstName", SqlDbType.VarChar, 50).Value = firstName;
        cmd.Parameters.Add("@Lastname", SqlDbType.VarChar, 50).Value = lastName;
        cmd.Parameters.Add("@Username", SqlDbType.VarChar, 50).Value = userName;
        cmd.Parameters.Add("@Password", SqlDbType.VarChar, 50).Value = password;
        cmd.Parameters.Add("@Age", SqlDbType.Int).Value = age;
        cmd.Parameters.Add("@Gender", SqlDbType.VarChar, 50).Value = gender;
        cmd.Parameters.Add("@Contact", SqlDbType.VarChar, 50).Value = contact;

        // open connection, execute INSERT, close connection
        cn.Open();
        cmd.ExecuteNonQuery();
        cn.Close();
    }
}

Code like this:

• is not vulnerable to SQL injection attacks
• performs much better on SQL Server (since the query is parsed once into an execution plan, then cached and reused later on)
• separates the event handler (code-behind file) from your actual database code (putting things where they belong - helping to avoid "overweight" code-behinds with tons of spaghetti code, doing everything from handling UI events to database access - NOT a good design!)

The setup feature does not work on Visual Studio 2017 and later versions.

The extension needs to be downloaded from VS Marketplace and then installed - Link

The same applies to other extensions such as Installer Projects (used for creating executable files) - Link

Empty refers to a variable being at its default value. So if you check if a cell with a value of 0 = Empty then it would return true.

IsEmpty refers to no value being initialized.

In a nutshell, if you want to see if a cell is empty (as in nothing exists in its value) then use IsEmpty. If you want to see if something is currently in its default value then use Empty.

Use below command:

$ git reset HEAD~1

After this you also able to view files what revert back like below response.

Unstaged changes after reset:
M   application/config/config.php
M   application/config/database.php

Add

t1.Join();    // Wait until thread t1 finishes

after you start it, but that won't accomplish much as it's essentialy the same result as running on the main thread!

I can highly recommended reading Joe Albahari's Threading in C# free e-book, if you want to gain an understanding of threading in .NET.

Imagine the .js files are placed in /my-site/some/path/ui/js/myfile.js

So normally the script tag would look like:

<script src="/my-site/some/path/ui/js/myfile.js"></script>

Now change that to:

<script src="/my-site/some/path/ui-1111111111/js/myfile.js"></script>

Now of course that will not work. To make it work you need to add one or a few lines to your .htaccess The important line is: (entire .htaccess at the bottom)

RewriteRule ^my-site\/(.*)\/ui\-([0-9]+)\/(.*) my-site/$1/ui/$3 [L]

So what this does is, it kind of removes the 1111111111 from the path and links to the correct path.

So now if you make changes you just have to change the number 1111111111 to whatever number you want. And however you include your files you can set that number via a timestamp when the js-file has last been modified. So cache will work normally if the number does not change. If it changes it will serve the new file (YES ALWAYS) because the browser get's a complete new URL and just believes that file is so new he must go get it.

You can use this for CSS, favicons and what ever gets cached. For CSS just use like so

<link href="http://my-domain.com/my-site/some/path/ui-1492513798/css/page.css" type="text/css" rel="stylesheet">

And it will work! Simple to update, simple to maintain.

The promised full .htaccess

If you have no .htaccess yet this is the minimum you need to have there:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    RewriteRule ^my-site\/(.*)\/ui\-([0-9]+)\/(.*) my-site/$1/ui/$3 [L]
</IfModule>

You can do git push --force but be aware that you are rewriting history and anyone using the repo will have issue with this.

If you want to prevent this problem, don't use reset, but instead use git revert

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

I always just use echo "<script> function(); </script>"; or something similar. you're not technically calling the function in PHP, but this as close as your going to get.

Also remember, when running on alternate ports, you need to specify the port on the URL:

http://www.example.com:8080

There may be firewalls or proxy servers to consider depending on your environment.

The pythonic way to read a file and put every lines in a list:

from __future__ import with_statement #for python 2.5
with open('C:/path/numbers.txt', 'r') as f:
    lines = f.readlines()

Then, assuming that each lines contains a number,

numbers =[int(e.strip()) for e in lines]

To remove node you can try this solution it helped me.

var rslt = (nodee=document.getElementById(id)).parentNode.removeChild(nodee);

You will need to import the other file as a module like this:

import Math

If you don't want to prefix your Calculate function with the module name then do this:

from Math import Calculate

If you want to import all members of a module then do this:

from Math import *

Edit: Here is a good chapter from Dive Into Python that goes a bit more in depth on this topic.

As per my understanding, When ever we execute print statements output will be written to buffer. And we will see the output on screen when buffer get flushed(cleared). By default buffer will be flushed when program exits. BUT WE CAN ALSO FLUSH THE BUFFER MANUALLY by using "sys.stdout.flush()" statement in the program. In the below code buffer will be flushed when value of i reaches 5.

You can understand by executing the below code.

chiru@online:~$ cat flush.py

import time
import sys

for i in range(10):
    print i
    if i == 5:
        print "Flushing buffer"
        sys.stdout.flush()
    time.sleep(1)

for i in range(10):
    print i,
    if i == 5:
        print "Flushing buffer"
        sys.stdout.flush()

chiru@online:~$ python flush.py 
0 1 2 3 4 5 Flushing buffer
6 7 8 9 0 1 2 3 4 5 Flushing buffer
6 7 8 9

I was facing issue .. then I removed JAVA_HOME variable completly and just added %JAVA_HOME%\bin in PATH then it worked!!! for mee

I had the same problem on localhost. Running around the Internet looking for the answer and I approve that adding --allow-file-access-from-files works. I work on Mac, so for me I had to go through terminal sudo /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --allow-file-access-from-files and enter your password (if you have one).

Another small thing - nothing will work unless you add to your .xml file the reference to your .xsl file as follows <?xml-stylesheet type="text/xsl" href="<path to file>"?>. Another small thing I didn't realise immediately - you should be opening your .xml file in browser, no the .xsl.

Like that. Except char hi=hello; should be char hi=hello.charAt(0). (Don't forget your break; statements).

Example more... attr() is various, val() is just one! Prop is boolean are different.

Most of these answers were written in Python version 2.x or earlier. In Python 3.x the syntax for the print function has changed to require parentheses, i.e. print().

So, this earlier high score answer from user13993 in Python 2.x:

import inspect, os
print inspect.getfile(inspect.currentframe()) # script filename (usually with path)
print os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))) # script directory

Becomes in Python 3.x:

import inspect, os
print(inspect.getfile(inspect.currentframe())) # script filename (usually with path)
print(os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))) ) # script directory

Since you have the manual user input loop, after the scanner has read your first input it will pass the carriage/return into the next line which will also be read; of course, that is not what you wanted.

You can try this

try {
    // ...
} catch (InputMismatchException e) {
    reader.next(); 
}

or alternatively, you can consume that carriage return before reading your next double input by calling

reader.next()

I realise this thread is quite old now, but I was having the same problem. This was my very basic solution using the MySQL Workbench, but it worked fine...

1. get a new sql editor and execute SHOW TABLES to get a list of your tables
2. select all of the rows, and choose copy to clipboard (unquoted) from the context menu
3. paste the list of names into another editor tab
4. write your query, ie ALTER TABLE x DROP a;
5. do some copying and pasting, so you end up with separate query for each table
6. Toggle whether the workbench should stop when an error occurs
7. Hit execute and look through the output log

any tables which had the table now haven't any tables which didn't will have shown an error in the logs

then you can find/replace 'drop a' change it to 'ADD COLUMN b INT NULL' etc and run the whole thing again....

a bit clunky, but at last you get the end result and you can control/monitor the whole process and remember to save you sql scripts in case you need them again.

Just try to re-create connection. In my situation one of jdbc connection stopped working for no reason. From console sqlplus was working ok. It took me 2 hours to realize that If i create the same connection - it works.

Delete Dan from employee.data - No need to manage a new data.frame.

employee.data <- subset(employee.data, name!="Dan")

This example might help you. by using simple casting you can get code behind urdu character.

string str = "?????";
        char ch = ' ';
        int number = 0;
        for (int i = 0; i < str.Length; i++)
        {
            ch = str[i];
            number = (int)ch;
            Console.WriteLine(number);
        }

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.
