Programs & Examples On #Zend db table

Try this updated code :

$(bla).click(function(){        
  if (something) {
     console.log($target.prev("input")) // gives out the right object
     $target.toggleClass("open").prev("input").attr("disabled", "true");
  }else{
     $target.toggleClass("open").prev("input").removeAttr("disabled"); //this works
  }
})

with open('input.json','r') as f:
    s = f.read()
    s = s.replace('\'','\"')
    data = json.loads(s)

This worked perfectly well for me. Thanks.

I faced the same problem and reason was that my app was not live and publicly available.

I added my email id in contact email under setting tabs and make my app live(which previously was disabled to make live).

After making my app live its showing sharing dialogue with proper image, title and description with my app name in bottom.

I use hebrew(RTL language) in strings.xml. I have manually searched the string.xml for this char: ' than I added the escape char \ infront of it (now it looks like \' ) and still got the same error!

I searched again for the char ' and I replaced the char ' with \'(eng writing) , since it shows a right to left it looks like that '\ in the strings.xml !!

Problem solved.

Assuming you have:

HashMap<Key, Value> map; // Assigned or populated somehow.

For a list of values:

List<Value> values = new ArrayList<Value>(map.values());

For a list of keys:

List<Key> keys = new ArrayList<Key>(map.keySet());

Note that the order of the keys and values will be unreliable with a HashMap; use a LinkedHashMap if you need to preserve one-to-one correspondence of key and value positions in their respective lists.

1. Select MainActivity.java file from the left pane, as shown in the red colored rectangle.

2. Left click the XML Tag icon as shown in the red colored circle.

3. Select the "activity_main.xml(layout)" option shown highlighted in the below figure.

Could it be this? http://docs.gunicorn.org/en/latest/settings.html#timeout

Other possibilities could be your response is taking too long or is stuck waiting.

You haven't posted the findvertex method, but Access Reading Violation with an offset like 0x00000048 means that the Vertex* f; in your getCost function is receiving null, and when trying to access the member adj in the null Vertex pointer (that is, in f), it is offsetting to adj (in this case, 72 bytes ( 0x48 bytes in decimal )), it's reading near the 0 or null memory address.

Doing a read like this violates Operating-System protected memory, and more importantly means whatever you're pointing at isn't a valid pointer. Make sure findvertex isn't returning null, or do a comparisong for null on f before using it to keep yourself sane (or use an assert):

assert( f != null ); // A good sanity check

EDIT:

If you have a map for doing something like a find, you can just use the map's find method to make sure the vertex exists:

Vertex* Graph::findvertex(string s)
{
    vmap::iterator itr = map1.find( s );
    if ( itr == map1.end() )
    {
        return NULL;
    }
    return itr->second;
}

Just make sure you're still careful to handle the error case where it does return NULL. Otherwise, you'll keep getting this access violation.

Check that the application on the test device and Google Play developer console really match.

I might have a bit of a special case but it might help someone: First, I had uploaded a package to Google Play that I had created with an ant build script. Second, on the test device, I debugged the same application (or so I thought). I got the "Error while retrieving information from server. [RPC:S-7:AEC-0]", and logcat displayed:

Class not found when unmarshalling: com.google.android.finsky.billing.lightpurchase.PurchaseParams, e: java.lang.ClassNotFoundException: com.google.android.finsky.billing.lightpurchase.PurchaseParams

The problem was that in the ant script, I have aapt command for modifying the package name. However, Eclipse does not run that command, so there was a package name mismatch between the applications in Google Play and the test device.

The grep family of commands (incl egrep, fgrep) is the usual solution for this.

$ grep pattern filename

If you're searching source code, then ack may be a better bet. It'll search subdirectories automatically and avoid files you'd normally not search (objects, SCM directories etc.)

On Windows use:

C:\PostgreSQL\pg10\bin>createuser -U postgres --pwprompt <USER>

Add --superuser or --createdb as appropriate.

See https://www.postgresql.org/docs/current/static/app-createuser.html for further options.

I don't think an implicit wait is what you want. Try this:

driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);

You can use directly replace function on javascript with regex or define a help function as in php ltrim(left) and rtrim(right):

1) With replace:

var myArray = ",'first string','more','even more'".replace(/^\s+/, '').split(/'?,?'/);

2) Help functions:

if (!String.prototype.ltrim) String.prototype.ltrim = function() {
    return this.replace(/^\s+/, '');
};
if (!String.prototype.rtrim) String.prototype.rtrim = function() {
    return this.replace(/\s+$/, '');
};
var myArray = ",'first string','more','even more'".ltrim().split(/'?,?'/).filter(function(el) {return el.length != 0});;

You can do and other things to add parameter to the help function with what you want to replace the char, etc.

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

Follow this simple steps; (Works on MAC OS too)

1. Open terminal and run sudo mongod

2. Open a new terminal tab(Don't close step 1 tab) and run sudo mongo

That's all

Why does it give me that error?

Because your first parameter you pass to the loop function is None but your function is expecting an callable object, which None object isn't.

Therefore you have to pass the callable-object which is in your case the hi function object.

def hi():     
  print 'hi'

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)

$_SERVER['HTTP_REFERER'] will give you incomplete url.

If you want http://bawse.3owl.com/jayz__magna_carta_holy_grail.php, $_SERVER['HTTP_REFERER'] will give you http://bawse.3owl.com/ only.

you can run this small php code

<?php
phpinfo();
?>

Copy the whole output page, paste it in this link. Then analyze. It will show if Xdebug is installed or not. And it will give instructions to complete the installation.

i was facing the same issue.. so instead of downloading font awesome , i added a link in my html code and it worked.

<script src="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.11.2/js/all.js" integrity="sha256-2JRzNxMJiS0aHOJjG+liqsEOuBb6++9cY4dSOyiijX4=" crossorigin="anonymous"></script>

This works:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

You mean something like this?

<?php

$jsonurl = "http://search.twitter.com/trends.json";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);

foreach ( $json_output->trends as $trend )
{
    echo "{$trend->name}\n";
}

GitHub pages host only static HTML pages. No server side technology is supported, so Node.js applications won't run on GitHub pages. There are lots of hosting providers, as listed on the Node.js wiki.

App fog seems to be the most economical as it provides free hosting for projects with 2GB of RAM (which is pretty good if you ask me).
As stated here, AppFog removed their free plan for new users.

If you want to host static pages on GitHub, then read this guide. If you plan on using Jekyll, then this guide will be very helpful.

I trained a neural network in Keras to perform non linear regression on some data. This is some part of my code for testing on new data using previously saved model configuration and weights.

fname = r"C:\Users\tauseef\Desktop\keras\tutorials\BestWeights.hdf5"
modelConfig = joblib.load('modelConfig.pkl')
recreatedModel = Sequential.from_config(modelConfig)
recreatedModel.load_weights(fname)
unseenTestData = np.genfromtxt(r"C:\Users\tauseef\Desktop\keras\arrayOf100Rows257Columns.txt",delimiter=" ")
X_test = unseenTestData
standard_scalerX = StandardScaler()
standard_scalerX.fit(X_test)
X_test_std = standard_scalerX.transform(X_test)
X_test_std = X_test_std.astype('float32')
unseenData_predictions = recreatedModel.predict(X_test_std)

Isn't that what hidden parameters are for to start with...?

<form action="http://www.example.com" method="GET">
  <input type="hidden" name="a" value="1" /> 
  <input type="hidden" name="b" value="2" /> 
  <input type="hidden" name="c" value="3" /> 
  <input type="submit" /> 
</form>

I wouldn't count on any browser retaining any existing query string in the action URL.

As the specifications (RFC1866, page 46; HTML 4.x section 17.13.3) state:

If the method is "get" and the action is an HTTP URI, the user agent takes the value of action, appends a `?' to it, then appends the form data set, encoded using the "application/x-www-form-urlencoded" content type.

Maybe one could percent-encode the action-URL to embed the question mark and the parameters, and then cross one's fingers to hope all browsers would leave that URL as it (and validate that the server understands it too). But I'd never rely on that.

By the way: it's not different for non-hidden form fields. For POST the action URL could hold a query string though.

You can also declare 'x' with the keyword var:

var x = new
{
  driver = new
  {
    firstName = "john",
    lastName = "walter"
  },
  car = new
  {
    brand = "BMW"
  }
};

This will allow you to declare your x object inline, but you will have to name your 2 anonymous objects, in order to access them. You can have an array of "x" :

x.driver.firstName // "john"
x.car.brand // "BMW"

var y = new[] { x, x, x, x };
y[1].car.brand; // "BMW"

You can use:

  import ipy_autoreload
  %autoreload 2 
  %aimport your_mod

I would recommend you to change Status cache of the Overlays.

Settings -> Icon Overlays -> Status cache

Maybe this would help to reinitialise the cache.

Be sure touse the latest version of Tortoise.

I resolved the error by force stopping (killed) git processes (ssh agent), then uninstalling Git, and then installing Git again.

In my case, I had to close R session and reinstall all packages. In that session I worked with large tables, I suspect this might have had the effect.

I found the same issue and tried everything. I have two different apps, one in objective-C and one in swift - both have the same problem. The error message comes in the debugger and the screen goes black after the first photo. This only happens in iOS >= 8.0, obviously it is a bug.

I found a difficult workaround. Shut off the camera controls with imagePicker.showsCameraControls = false and create your own overlayView that has the missing buttons. There are various tutorials around how to do this. The strange error message stays, but at least the screen doesn't go black and you have a working app.

Another reason this can happen is if you send the wrong appId. This can happen in early development if you have a development app and a production app. If you hard-code the appId for dev and push to prod, this will show up.

You can use capturing groups to organize and parse an expression. A non-capturing group has the first benefit, but doesn't have the overhead of the second. You can still say a non-capturing group is optional, for example.

Say you want to match numeric text, but some numbers could be written as 1st, 2nd, 3rd, 4th,... If you want to capture the numeric part, but not the (optional) suffix you can use a non-capturing group.

([0-9]+)(?:st|nd|rd|th)?

That will match numbers in the form 1, 2, 3... or in the form 1st, 2nd, 3rd,... but it will only capture the numeric part.

I just had a jaw-drop moment - Termux allows you to install NodeJS on an Android device!

It seems to work for a basic Websocket Speed Test I had on hand. The http served by it can be accessed both locally and on the network.

There is a medium post that explains the installation process

Basically: 1. Install termux 2. apt install nodejs 3. node it up!

One restriction I've run into - it seems the shared folders don't have the necessary permissions to install modules. It might just be a file permission thing. The private app storage works just fine.

disable button:

$('#button_id').attr('disabled','disabled');

enable button:

$('#button_id').removeAttr('disabled');

None of the answers above seemed to properly serialize properties which are on the prototype of Error (because getOwnPropertyNames() does not include inherited properties). I was also not able to redefine the properties like one of the answers suggested.

This is the solution I came up with - it uses lodash but you could replace lodash with generic versions of those functions.

 function recursivePropertyFinder(obj){
    if( obj === Object.prototype){
        return {};
    }else{
        return _.reduce(Object.getOwnPropertyNames(obj), 
            function copy(result, value, key) {
                if( !_.isFunction(obj[value])){
                    if( _.isObject(obj[value])){
                        result[value] = recursivePropertyFinder(obj[value]);
                    }else{
                        result[value] = obj[value];
                    }
                }
                return result;
            }, recursivePropertyFinder(Object.getPrototypeOf(obj)));
    }
}


Error.prototype.toJSON = function(){
    return recursivePropertyFinder(this);
}

Here's the test I did in Chrome:

var myError = Error('hello');
myError.causedBy = Error('error2');
myError.causedBy.causedBy = Error('error3');
myError.causedBy.causedBy.displayed = true;
JSON.stringify(myError);

{"name":"Error","message":"hello","stack":"Error: hello\n    at <anonymous>:66:15","causedBy":{"name":"Error","message":"error2","stack":"Error: error2\n    at <anonymous>:67:20","causedBy":{"name":"Error","message":"error3","stack":"Error: error3\n    at <anonymous>:68:29","displayed":true}}}

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

See here:

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.html

the reason of the exception has been explained already, however the suggested solution isn't really the best.

You should create a class that keeps a Scanner as private using Singleton Pattern, that makes that scanner unique on your code.

Then you can implement the methods you need or you can create a getScanner ( not recommended ) and you can control it with a private boolean, something like alreadyClosed.

If you are not aware how to use Singleton Pattern, here's a example:

public class Reader {
    
    
    private Scanner reader;
    private static Reader singleton = null;
    private boolean alreadyClosed;
    
    private Reader() {
        alreadyClosed = false;
        reader = new Scanner(System.in);
    }
    
    public static Reader getInstance() {
        if(singleton == null) {
            singleton = new Reader();
        }
        return singleton;
    }
    
    public int nextInt() throws AlreadyClosedException {
        if(!alreadyClosed) {
            return reader.nextInt();
        }
        throw new AlreadyClosedException(); //Custom exception
    }
    
    public double nextDouble() throws AlreadyClosedException {
        if(!alreadyClosed) {
            return reader.nextDouble();
        }
        throw new AlreadyClosedException();
    }
    
    public String nextLine() throws AlreadyClosedException {
        if(!alreadyClosed) {
            return reader.nextLine();
        }
        throw new AlreadyClosedException();
    }
    
    public void close() {
        alreadyClosed = true;
        reader.close();
    }   
}

Simply place normal button indide Ajax.BeginForm and on click find parent form and normal submit. Ajax form in Razor:

@using (Ajax.BeginForm("AjaxPost", "Home", ajaxOptions))
    {        
        <div class="form-group">
            <div class="col-md-12">

                <button class="btn btn-primary" role="button" type="button" onclick="submitParentForm($(this))">Submit parent from Jquery</button>
            </div>
        </div>
    }

and Javascript:

function submitParentForm(sender) {
    var $formToSubmit = $(sender).closest('form');

    $formToSubmit.submit();
}

I found that the repo that had the package was not enabled. On OEL7,

$ vi /etc/yum.repos.d/ULN-Base.repo
Set enabled to 1 for ol7_optional_latest

$ yum install php-bcmath

and that worked...

I used the following command to find where the package was

$ yum --noplugins --showduplicates --enablerepo \* --disablerepo \*-source --disablerepo C5.\*,c5-media,\*debug\*,\*-source list \*bcmath

Cells(1,1).Value2 = "'123,456"

note the single apostrophe before the number - this will signal to excel that whatever follows has to be interpreted as text.

.article-img img{ 
    height: 100%;
    width: 100%;
    position: relative;
    vertical-align: middle;
    border-style: none;
 }

You will make images size same as div and you can use bootstrap grid to manipulate div size accordingly

I've had the same error parsing a string containing \n into JSON. The solution was to use string.replace('\n','\\n')

To expand on @PhiLho answer, you can center a very large image (or any size image) on a page with:

{ 
background-image: url(_images/home.jpg);
background-repeat:no-repeat;
background-position:center; 
}

Or you could use a smaller image with a background color that matches the background of the image (if it is a solid color). This may or may not suit your purposes.

{ 
background-color: green;
background-image: url(_images/home.jpg);
background-repeat:no-repeat;
background-position:center; 
}

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!

You can simply reset the root password by running the server with --skip-grant-tables and logging in without a password by running the following as root or with sudo:

service mysql stop
mysqld_safe --skip-grant-tables &
mysql -u root

mysql> use mysql;
mysql> update user set authentication_string=PASSWORD("YOUR-NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
mysql> quit

# service mysql stop
# service mysql start
$ mysql -u root -p

Adding libraries with resources To add a Support Library with resources (such as v7 appcompat for action bar) to your application project:

Using Eclipse

Create a library project based on the support library code:

• Make sure you have downloaded the Android Support Library using the SDK Manager.

• Create a library project and ensure the required JAR files are included in the project's build path:

• Select File > Import.

• Select Existing Android Code Into Workspace and click Next.

• Browse to the SDK installation directory and then to the Support Library folder. For example, if you are adding the appcompat project, browse to /extras/android/support/v7/appcompat/.

• Click Finish to import the project. For the v7 appcompat project, you should now see a new project titled android-support-v7-appcompat.

• In the new library project, expand the libs/ folder, right-click each .jar file and select Build

• Path > Add to Build Path. For example, when creating the the v7 appcompat project, add both the android-support-v4.jar and android-support-v7-appcompat.jar files to the build path.

• Right-click the library project folder and select Build Path > Configure Build Path.

• In the Order and Export tab, check the .jar files you just added to the build path, so they are available to projects that depend on this library project. For example, the appcompat project requires you to export both the android-support-v4.jar and android-support-v7-appcompat.jar files.

• Uncheck Android Dependencies.

• Click OK to complete the changes.

• You now have a library project for your selected Support Library that you can use with one or more application projects.

• Add the library to your application project:

• In the Project Explorer, right-click your project and select Properties.

• In the category panel on the left side of the dialog, select Android.

• In the Library pane, click the Add button.

• Select the library project and click OK. For example, the appcompat project should be listed as android-support-v7-appcompat.

• In the properties window, click OK.

While this does not directly answer the question, it is related.

This way you don't need to keep creating/iterating. Just create a reverse map once and get what you need.

/**
 * Both key and value types must define equals() and hashCode() for this to work.
 * This takes into account that all keys are unique but all values may not be.

 * @return
 */
public static <K, V> Map<V, List<K>> reverseMap(Map<K,V> map) {
    if(map == null) return null;

    Map<V, List<K>> reverseMap = new ArrayMap<>();

    for(Map.Entry<K,V> entry : map.entrySet()) {
        appendValueToMapList(reverseMap, entry.getValue(), entry.getKey());
    }

    return reverseMap;
}


/**
 * Takes into account that the list may already have values.
 * 
 * @param map
 * @param key

 */
public static <K, V> Map<K, List<V>> appendValueToMapList(Map<K, List<V>> map, K key, V value) {
    if(map == null || key == null || value == null) return map;

    List<V> list = map.get(key);

    if(list == null) {
        List<V> newList = new ArrayList<>();
        newList.add(value);
        map.put(key, newList);
    }
    else {
        list.add(value);
    }

    return map;
}

If you were running a 64 bit platform you would see x86_64 or something very similar in the output from uname -a

To get your specific machine hardware name run

uname -m

You can also call

getconf LONG_BIT

which returns either 32 or 64

We can use paste0:

df$combField <- paste0(df$x, df$y)

If you do not want any padding space introduced in the concatenated field. This is more useful if you are planning to use the combined field as a unique id that represents combinations of two fields.

I have found a way to get the desired output. Though it may be somewhat unorthodox way. Anyways here it goes. In the redir.env file I have following code:

#####redir.env#####    
export LOG_FILE=log.txt

      exec 2>>${LOG_FILE}

    function log {
     echo "$1">>${LOG_FILE}
    }

    function message {
     echo "$1"
     echo "$1">>${LOG_FILE}
    }

Then in the actual script I have the following codes:

#!/bin/sh 
. redir.env
echo "Echoed to console only"
log "Written to log file only"
message "To console and log"
echo "This is stderr. Written to log file only" 1>&2

Here echo outputs only to console, log outputs to only log file and message outputs to both the log file and console.

After executing the above script file I have following outputs:

In console

In console
Echoed to console only
To console and log

For the Log file

In Log File Written to log file only
This is stderr. Written to log file only
To console and log

Hope this help.

you can simply use,

var className = $('#id').attr('class');

It's not built into the SDK, but you can use the Zxing library. It's free, open source, and Apache-licensed.

The 2016 recommendation is to use the Barcode API, which also works offline.

If you want to use rollback, then use start transaction and otherwise forget all those things,

By default, MySQL automatically commits the changes to the database.

To force MySQL not to commit these changes automatically, execute following:

SET autocommit = 0;
//OR    
SET autocommit = OFF

To enable the autocommit mode explicitly:

SET autocommit = 1;
//OR    
SET autocommit = ON;

In Spring, those objects that form the backbone of your application and that are managed by the Spring IoC container are referred to as beans. A bean is simply an object that is instantiated, assembled and otherwise managed by a Spring IoC container;

OUTPUT

List size is : 4

List Elements are  : [8.8.8.8, 8.8.4.4, 156.154.70.1, 156.154.71.1]

https://lodash.com/docs#isEmpty comes in pretty handy:

_.isEmpty({})   // true
_.isEmpty()     // true
_.isEmpty(null) // true
_.isEmpty("")   // true

Eulerian path must visit each edge exactly once, while Hamiltonian path must visit each vertex exactly once.

Also useful is the coalesce operator ??:

VB:

Return Iif( s IsNot Nothing, s, "My Default Value" )

C#:

return s ?? "My Default Value";

The currently selected solution produces incorrect results. To correctly solve this problem, we can perform a left-join from df1 to df2, making sure to first get just the unique rows for df2.

First, we need to modify the original DataFrame to add the row with data [3, 10].

df1 = pd.DataFrame(data = {'col1' : [1, 2, 3, 4, 5, 3], 
                           'col2' : [10, 11, 12, 13, 14, 10]}) 
df2 = pd.DataFrame(data = {'col1' : [1, 2, 3],
                           'col2' : [10, 11, 12]})

df1

   col1  col2
0     1    10
1     2    11
2     3    12
3     4    13
4     5    14
5     3    10

df2

   col1  col2
0     1    10
1     2    11
2     3    12

Perform a left-join, eliminating duplicates in df2 so that each row of df1 joins with exactly 1 row of df2. Use the parameter indicator to return an extra column indicating which table the row was from.

df_all = df1.merge(df2.drop_duplicates(), on=['col1','col2'], 
                   how='left', indicator=True)
df_all

   col1  col2     _merge
0     1    10       both
1     2    11       both
2     3    12       both
3     4    13  left_only
4     5    14  left_only
5     3    10  left_only

Create a boolean condition:

df_all['_merge'] == 'left_only'

0    False
1    False
2    False
3     True
4     True
5     True
Name: _merge, dtype: bool

Why other solutions are wrong

A few solutions make the same mistake - they only check that each value is independently in each column, not together in the same row. Adding the last row, which is unique but has the values from both columns from df2 exposes the mistake:

common = df1.merge(df2,on=['col1','col2'])
(~df1.col1.isin(common.col1))&(~df1.col2.isin(common.col2))
0    False
1    False
2    False
3     True
4     True
5    False
dtype: bool

This solution gets the same wrong result:

df1.isin(df2.to_dict('l')).all(1)

After reading all the posts here, i settled on the consolidated solution of Marko Avlijaš. However, it did not solve all of my issues.

In our environment we have a Windows Service which is scheduled to run hundreds of different .bat .cmd .exe,... etc. files which have accumulated over the years and were written by many different people and in different styles. We have no control over the writing of the programs & scripts, we are just responsible for scheduling, running, and reporting on success/failure.

So i tried pretty much all of the suggestions here with different levels of success. Marko's answer was almost perfect, but when run as a service, it didnt always capture stdout. I never got to the bottom of why not.

The only solution we found that works in ALL our cases is this : http://csharptest.net/319/using-the-processrunner-class/index.html

Since HTTP Params class is immutable therefore you need to chain the set method:

const params = new HttpParams()
.set('aaa', '111')
.set('bbb', "222");

As stated in other answers, you can check the mime type by checking the signature of the file in the first bytes of the file.

But what other answers are doing is loading the entire file in memory in order to check the signature, which is very wasteful and could easily freeze your browser if you select a big file by accident or not.

Use the apache commons cli if you plan on extending that past a single arg.

"The Apache Commons CLI library provides an API for parsing command line options passed to programs. It's also able to print help messages detailing the options available for a command line tool."

Commons CLI supports different types of options:

• POSIX like options (ie. tar -zxvf foo.tar.gz)
• GNU like long options (ie. du --human-readable --max-depth=1)
• Java like properties (ie. java -Djava.awt.headless=true -Djava.net.useSystemProxies=true Foo)
• Short options with value attached (ie. gcc -O2 foo.c)
• long options with single hyphen (ie. ant -projecthelp)

Also check this answer from here: Cannot manually edit applicationhost.config

The answer is simple, if not that obvious: win2008 is 64bit, notepad++ is 32bit. When you navigate to Windows\System32\inetsrv\config using explorer you are using a 64bit program to find the file. When you open the file using using notepad++ you are trying to open it using a 32bit program. The confusion occurs because, rather than telling you that this is what you are doing, windows allows you to open the file but when you save it the file's path is transparently mapped to Windows\SysWOW64\inetsrv\Config.

So in practice what happens is you open applicationhost.config using notepad++, make a change, save the file; but rather than overwriting the original you are saving a 32bit copy of it in Windows\SysWOW64\inetsrv\Config, therefore you are not making changes to the version that is actually used by IIS. If you navigate to the Windows\SysWOW64\inetsrv\Config you will find the file you just saved.

How to get around this? Simple - use a 64bit text editor, such as the normal notepad that ships with windows.

we all know generally that for sending the data according to the http standards we generally use POST request. But if you really want to use Get for sending the data in your scenario I would suggest you to use the query-string or query-parameters.

1.GET use of Query string as. {{url}}admin/recordings/some_id

here the some_id is mendatory parameter to send and can be used and req.params.some_id at server side.

2.GET use of query string as{{url}}admin/recordings?durationExact=34&isFavourite=true

here the durationExact ,isFavourite is optional strings to send and can be used and req.query.durationExact and req.query.isFavourite at server side.

3.GET Sending arrays {{url}}admin/recordings/sessions/?os["Windows","Linux","Macintosh"]

and you can access those array values at server side like this

let osValues = JSON.parse(req.query.os);
        if(osValues.length > 0)
        {
            for (let i=0; i<osValues.length; i++)
            {
                console.log(osValues[i])
                //do whatever you want to do here
            }
        }

Node.js was created explicitly as an experiment in async processing. The theory was that doing async processing on a single thread could provide more performance and scalability under typical web loads than the typical thread-based implementation.

And you know what? In my opinion that theory's been borne out. A node.js app that isn't doing CPU intensive stuff can run thousands more concurrent connections than Apache or IIS or other thread-based servers.

The single threaded, async nature does make things complicated. But do you honestly think it's more complicated than threading? One race condition can ruin your entire month! Or empty out your thread pool due to some setting somewhere and watch your response time slow to a crawl! Not to mention deadlocks, priority inversions, and all the other gyrations that go with multithreading.

In the end, I don't think it's universally better or worse; it's different, and sometimes it's better and sometimes it's not. Use the right tool for the job.

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

Assuming you want a list containing all of the products for the specified category-Ids, you can treat your query as a projection followed by a flattening operation. There's a LINQ operator that does that: SelectMany.

// implicitly List<Product>
var products = new[] { CategoryId1, CategoryId2, CategoryId3 }
                     .SelectMany(id => GetAllProducts(id))
                     .ToList();

In C# 4, you can shorten the SelectMany to: .SelectMany(GetAllProducts)

If you already have lists representing the products for each Id, then what you need is a concatenation, as others point out.

I found JXDatePicker as a better solution to this. It gives what you need and very easy to use.

import java.text.SimpleDateFormat;
import java.util.Calendar;
import javax.swing.JFrame;
import javax.swing.JPanel;
import org.jdesktop.swingx.JXDatePicker;

public class DatePickerExample extends JPanel {

    public static void main(String[] args) {
        JFrame frame = new JFrame("JXPicker Example");
        JPanel panel = new JPanel();

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setBounds(400, 400, 250, 100);

        JXDatePicker picker = new JXDatePicker();
        picker.setDate(Calendar.getInstance().getTime());
        picker.setFormats(new SimpleDateFormat("dd.MM.yyyy"));

        panel.add(picker);
        frame.getContentPane().add(panel);

        frame.setVisible(true);
    }
}

For npm

 npm install --save core-js@^3

for yarn

yarn add core-js@^3

In Linux:

java -version

In Windows:

java.exe -version

If you need more info about the JVM you can call the executable with the parameter -XshowSettings:properties. It will show a lot of System Properties. These properties can also be accessed by means of the static method System.getProperty(String) in a Java class. As example this is an excerpt of some of the properties that can be obtained:

$ java -XshowSettings:properties -version
[...]
java.specification.version = 1.7
java.vendor = Oracle Corporation
java.vendor.url = http://java.oracle.com/
java.vendor.url.bug = http://bugreport.sun.com/bugreport/
java.version = 1.7.0_95
[...]

So if you need to access any of these properties from Java code you can use:

System.getProperty("java.specification.version");
System.getProperty("java.vendor");
System.getProperty("java.vendor.url");
System.getProperty("java.version");

Take into account that sometimes the vendor is not exposed as clear as Oracle or IBM. For example,

$ java version
"1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

HotSpot is what Oracle calls their implementation of the JVM. Check this list if the vendor does not seem to be shown with -version.

os.path provides many functions for manipulating paths/filenames. (docs)

os.path.splitext takes a path and splits the file extension from the end of it.

import os

filepaths = ["/folder/soundfile.mp3", "folder1/folder/soundfile.flac"]

for fp in filepaths:
    # Split the extension from the path and normalise it to lowercase.
    ext = os.path.splitext(fp)[-1].lower()

    # Now we can simply use == to check for equality, no need for wildcards.
    if ext == ".mp3":
        print fp, "is an mp3!"
    elif ext == ".flac":
        print fp, "is a flac file!"
    else:
        print fp, "is an unknown file format."

Gives:

/folder/soundfile.mp3 is an mp3!
folder1/folder/soundfile.flac is a flac file!

Here is some code, nothing rocket science but it works well enough

require 'rubygems'
require 'rainbow'
if defined?(var).nil?  # .nil? is optional but might make for clearer intent.
 print "var is not defined\n".color(:red)
else
 print "car is defined\n".color(:green)
end

Clearly, the colouring code is not necessary, just a nice visualation in this toy example.

You can use ping -a <ip> or nbtstat -A <ip>

If you have default parameters in your base constructor the base class will be called automatically.

using namespace std;

class Base
{
    public:
    Base(int a=1) : _a(a) {}

    protected:
    int _a;
};

class Derived : public Base
{
  public:
  Derived() {}

  void printit() { cout << _a << endl; }
};

int main()
{
   Derived d;
   d.printit();
   return 0;
}

Output is: 1

One solution could be to wrap the options inside optgroup:

optgroup { font-size:40px; }

<select>
  <optgroup>
    <option selected="selected" class="service-small">Service area?</option>
    <option class="service-small">Volunteering</option>
    <option class="service-small">Partnership &amp; Support</option>
    <option class="service-small">Business Services</option>
  </optgroup>
</select>

In my case I had special instruction into nginx configuration file:

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            try_files $uri =404;
    }

All clients have received '404' because nginx nothing known about Flask.

I hope it help someone.

Here's how do to it with the SSDB catalog that was introduced with SQL Server 2012...

using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Data.SqlClient;

using Microsoft.SqlServer.Management.IntegrationServices;

public List<string> ExecutePackage(string folder, string project, string package)
{
    // Connection to the database server where the packages are located
    SqlConnection ssisConnection = new SqlConnection(@"Data Source=.\SQL2012;Initial Catalog=master;Integrated Security=SSPI;");

    // SSIS server object with connection
    IntegrationServices ssisServer = new IntegrationServices(ssisConnection);

    // The reference to the package which you want to execute
    PackageInfo ssisPackage = ssisServer.Catalogs["SSISDB"].Folders[folder].Projects[project].Packages[package];

    // Add a parameter collection for 'system' parameters (ObjectType = 50), package parameters (ObjectType = 30) and project parameters (ObjectType = 20)
    Collection<PackageInfo.ExecutionValueParameterSet> executionParameter = new Collection<PackageInfo.ExecutionValueParameterSet>();

    // Add execution parameter (value) to override the default asynchronized execution. If you leave this out the package is executed asynchronized
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "SYNCHRONIZED", ParameterValue = 1 });

    // Add execution parameter (value) to override the default logging level (0=None, 1=Basic, 2=Performance, 3=Verbose)
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "LOGGING_LEVEL", ParameterValue = 3 });

    // Add a project parameter (value) to fill a project parameter
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 20, ParameterName = "MyProjectParameter", ParameterValue = "some value" });

    // Add a project package (value) to fill a package parameter
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 30, ParameterName = "MyPackageParameter", ParameterValue = "some value" });

    // Get the identifier of the execution to get the log
    long executionIdentifier = ssisPackage.Execute(false, null, executionParameter);

    // Loop through the log and do something with it like adding to a list
    var messages = new List<string>();
    foreach (OperationMessage message in ssisServer.Catalogs["SSISDB"].Executions[executionIdentifier].Messages)
    {
        messages.Add(message.MessageType + ": " + message.Message);
    }

    return messages;
}

if you are using Swift Mailer: please ensure that your $transport variable is similar to the below, based on tests i have done, that error results from ssl and port misconfiguration. note: you must include 'ssl' or 'tls' in the transport variable.

EXAMPLE CODE:

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))
  ->setUsername([email protected])
  ->setPassword(password)
;

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('News Letter Subscription'))
  ->setFrom(['[email protected]' => 'A Name'])
  ->setTo(['[email protected]' => 'A Name'])
  ->setBody('your message body')
  ;

// Send the message
$result = $mailer->send($message);

Below is my solution - taking into account that the diffed tables can have duplicate rows. The accepted answer does not take this into account which would give you wrong results in case of duplicates. I am taking care of duplicate rows by numbering them using row_number() and then comparing the numbered rows:

-- TEST TABLES
create table t1 (col_num number,col_date date,col_varchar varchar2(400));
create table t2 (col_num number,col_date date,col_varchar varchar2(400));  

-- TEST DATA
insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am in both');
insert into t2 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am in both');

insert into t1 values (null,null,'I am in both with nulls');
insert into t2 values (null,null,'I am in both with nulls');

insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am in T1 only');
insert into t2 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am in T2 only');

insert into t1 values (null,null,'I am in T1 only with nulls');
insert into t2 values (null,null,'I am in T2 only with nulls');

insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T1 but not in T2');
insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T1 but not in T2');

insert into t2 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T2 but not in T1');
insert into t2 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T2 but not in T1');

insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T1 and once in T2');
insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T1 and once in T2');

insert into t2 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T2 and once in T1');
insert into t2 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T2 and once in T1');
insert into t1 values (1,TO_DATE ('01.JAN.3000 00:00:00', 'DD.MON.YYYY HH24:MI:SS'),'I am twice in T2 and once in T1');

-- THE DIFF
-- All columns need to be named in the partition by clause, it is not possible to just say 'partition by *'
-- The column used in the order by clause does not matter in terms of functionality

Using Android's built in method

If you want every column and every row, then just pass in null for the SQLiteDatabase column and selection parameters.

Cursor cursor = db.query(TABLE_NAME, null, null, null, null, null, null, null);

More details

The other answers use rawQuery, but you can use Android's built in SQLiteDatabase. The documentation for query says that you can just pass in null to the selection parameter to get all the rows.

selection Passing null will return all rows for the given table.

And while you can also pass in null for the column parameter to get all of the columns (as in the one-liner above), it is better to only return the columns that you need. The documentation says

columns Passing null will return all columns, which is discouraged to prevent reading data from storage that isn't going to be used.

Example

SQLiteDatabase db = mHelper.getReadableDatabase();
String[] columns = {
        MyDatabaseHelper.COLUMN_1,
        MyDatabaseHelper.COLUMN_2,
        MyDatabaseHelper.COLUMN_3};
String selection = null; // this will select all rows
Cursor cursor = db.query(MyDatabaseHelper.MY_TABLE, columns, selection,
        null, null, null, null, null);

I had the same error and I solved it by importing HttpModule in app.module.ts

import { HttpModule } from '@angular/http';

and then in the imports[] array:

i had the same problem until i downloaded bootstrap-tab.js and included it in my script, download from here https://code.google.com/p/fusionleaf/source/browse/webroot/fusionleaf/com/www/inc/bootstrap/js/bootstrap-tab.js?r=82aacd63ee1f7f9a15ead3574fe2c3f45b5c1027

Have you added the dll into your project references list? If not right click on the project "References" folder and selecet "Add Reference" then use browse to locate your science.dll, select it and click ok.

edit

I can't see the image of your VS instance that some people are referring to and I note that you now say that it works in Net4.0 and VS2010.

VS2008 projects support NET 3.5 by default. I expect that is the problem as your DLL may be NET 4.0 compliant but not NET 3.5.

If you have your dates in DateTime variables, they don't have a format.

You can use the Date property to return a DateTime value with the time portion set to midnight. So, if you have:

DateTime dt1 = DateTime.Parse("07/12/2011");
DateTime dt2 = DateTime.Now;

if(dt1.Date > dt2.Date)
{
     //It's a later date
}
else
{
     //It's an earlier or equal date
}

To get the maximum value of a column across a set of rows:

SELECT MAX(column1) FROM table; -- expect one result

To get the maximum value of a set of columns, literals, or variables for each row:

SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results

More efficient way

I suggest you to draw a circle with CustomPainter. It's very easy and way more efficient than creating a bunch of widgets/masks:

/// Draws a circle if placed into a square widget.
class CirclePainter extends CustomPainter {
  final _paint = Paint()
    ..color = Colors.red
    ..strokeWidth = 2
    // Use [PaintingStyle.fill] if you want the circle to be filled.
    ..style = PaintingStyle.stroke;

  @override
  void paint(Canvas canvas, Size size) {
    canvas.drawOval(
      Rect.fromLTWH(0, 0, size.width, size.height),
      _paint,
    );
  }

  @override
  bool shouldRepaint(CustomPainter oldDelegate) => false;
}

Usage:

  Widget _buildCircle(BuildContext context) {
    return SizedBox(
      width: 20,
      height: 20,
      child: CustomPaint(
        painter: CirclePainter(),
      ),
    );
  }

In both: Anaconda prompt and the old cmd.exe, you change your directory by first changing to the drive you want, by simply writing its name followed by a ':', exe: F: , which will take you to the drive named 'F' on your machine. Then using the command cd to navigate your way inside that drive as you normally would.

Recently, I faced similar problem and I solved it using following approach

def round(value: Either[Double, Float], places: Int) = {
  if (places < 0) 0
  else {
    val factor = Math.pow(10, places)
    value match {
      case Left(d) => (Math.round(d * factor) / factor)
      case Right(f) => (Math.round(f * factor) / factor)
    }
  }
}

def round(value: Double): Double = round(Left(value), 0)
def round(value: Double, places: Int): Double = round(Left(value), places)
def round(value: Float): Double = round(Right(value), 0)
def round(value: Float, places: Int): Double = round(Right(value), places)

I used this SO issue. I have couple of overloaded functions for both Float\Double and implicit\explicit options. Note that, you need to explicitly mention the return type in case of overloaded functions.

With Spring you could easily read it from the resources folder (either main/resources or test/resources):

For example create a file: test/resources/subfolder/sample.json

@Test
public void testReadFile() {
    String json = this.readFile("classpath:subfolder/sample.json");
    System.out.println(json);
}

public String readFile(String path) {
    try {
        File file = ResourceUtils.getFile(path);
        return new String(Files.readAllBytes(file.toPath()));
    } catch (IOException e) {
        e.printStackTrace();
    }

    return null;
}

NOTE: the answer that says to use the ZZ command doesn't work for me on my Mavericks system, but this is probably due to something in my vim configuration because if I start with a pristine .vimrc, the accepted answer works. My answer might work for you if the other solution doesn't.

On MacOS X, according to the crontab manpage, the crontab temporary file that gets created with crontab -e needs to be edited in-place. Vim doesn't edit in-place by default (but it might do some special case to support crontab -e), so if your $EDITOR environment variable is set to vi (the default) or vim, editing the crontab will always fail.

To get Vim to edit the file in-place, you need to do:

:setlocal nowritebackup

That should enable you to update the crontab when you do crontab -e with the :wq or ZZ commands.

You can add an autocommand in your .vimrc to make this automatically work when editing crontabs:

autocmd FileType crontab setlocal nowritebackup

Another way is to add the setlocal nowritebackup to ~/.vim/after/ftplugin/crontab.vim, which will be loaded by Vim automatically when you're editing a crontab file if you have the Filetype plugin enabled. You can also check for the OS if you're using your vim files across multiple platforms:

""In ~/.vim/after/ftplugin/crontab.vim
if has("mac")
  setlocal nowritebackup
endif

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

In the example you gave, the method will never throw an IOException, therefore the declaration is wrong (but valid). My guess is that the original method threw the IOException, but it was then updated to handle the exception within but the declaration was not changed.

Although they vary slightly as to how they retrieve a height value, i.e some would calculate the whole element including padding, margin, scrollbar, etc and others would just calculate the element in its raw form.
You can try these ones:

javascript:

var myDiv = document.getElementById("myDiv");
myDiv.clientHeight;
myDiv.scrollHeight;
myDiv.offsetHeight;

or in jquery:

$("#myDiv").height();
$("#myDiv").innerHeight();
$("#myDiv").outerHeight();

CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.

Use a border-radius property of 50%.

So for example:

.example-div {

    border-radius: 50%

}

First make your data base offline after that detach it e.g.

Use Master
GO
ALTER DATABASE dbname SET OFFLINE
GO
EXEC sp_detach_db 'dbname', 'true'

u can also show a certain number of digit after decimal point(here 2 digits) using following code :

var num = (15.46974).toFixed(2)_x000D_
console.log(num) // 15.47_x000D_
console.log(typeof num) // string

This worked for me:

git ls-files -m | xargs -L 1 chmod 644

Every method present in StringBuffer is Synchronized. hence at a time only one thread is allowed to operate StringBuffer object. It Increases waiting time of a Thread and Creates Performance problems to overcome this problem SUN People intoduced StringBuilder in 1.5 version.

Reverse merge is exactly what you want (see luapyad's answer). Just apply the merge to the erroneously-commited file instead of the entire directory.

If you're using RHEL, CentOS, Oracle Linux, etc. You can use yum to install tkinter module

yum install tkinter

when new allocates an array, depending on the compiler (i use gnu c++), the word in front of the array contains information about the number of bytes allocated.

The test code:

#include <stdio.h>
#include <stdlib.h>

int
main ()
{
    int arraySz;
    char *a;
    unsigned int *q;

    for (arraySz = 5; arraySz <= 64; arraySz++) {

        printf ("%02d - ", arraySz);

        a = new char[arraySz];
        unsigned char *p = (unsigned char *) a;

        q = (unsigned int *) (a - 4);
        printf ("%02d\n", (*q));

        delete[] (a);

    }
}

on my machine dumps out:

I would not recommend this solution (vector is better), but if you are really desperate, you could find a relationship and be able to conclude the number of bytes allocated from the heap.

You can clear your bash history like this:

I was trying do the same of making a particular file my default page, instead of directory structure. So in IIS server I had to go to Default Document, add the page that I want to make as default and at the same time, go to the Web.config file and update the defaultDocument header with "enabled=true". This worked for me. Hopefully it helps.

chmod 400 mykey.pem

ssh -i mykey.pem [email protected]

Will connect you over ssh using a .pem file to any server.

A late answer, yet another definition:

A package is represented by an imported top-entity which could either be a self-contained module, or the __init__.py special module as the top-entity from a set of modules within a sub directory structure.

So physically a package is a distribution unit, which provides one or more modules.

but what I got is something like this: Date@124bbbf  
while I change the import to: import java.util.Date;  
the code works perfectly, why? 

What do you mean by "works perfectly"? The output of printing a Date object is the same no matter whether you imported java.util.* or java.util.Date. The output that you get when printing objects is the representation of the object by the toString() method of the corresponding class.

If it's available to you, then it's difficult to think of a reason not to use the Java 5 executor framework. Calling:

ScheduledExecutorService ex = Executors.newSingleThreadScheduledExecutor();

will give you a ScheduledExecutorService with similar functionality to Timer (i.e. it will be single-threaded) but whose access may be slightly more scalable (under the hood, it uses concurrent structures rather than complete synchronization as with the Timer class). Using a ScheduledExecutorService also gives you advantages such as:

• You can customize it if need be (see the newScheduledThreadPoolExecutor() or the ScheduledThreadPoolExecutor class)
• The 'one off' executions can return results

About the only reasons for sticking to Timer I can think of are:

• It is available pre Java 5
• A similar class is provided in J2ME, which could make porting your application easier (but it wouldn't be terribly difficult to add a common layer of abstraction in this case)

The idea behind StandardScaler is that it will transform your data such that its distribution will have a mean value 0 and standard deviation of 1.
In case of multivariate data, this is done feature-wise (in other words independently for each column of the data).
Given the distribution of the data, each value in the dataset will have the mean value subtracted, and then divided by the standard deviation of the whole dataset (or feature in the multivariate case).

int a = 3;
int b = 2;
float c = ((float)a)/b

I had the same issue and I have gone through all these solutions given, but none of them worked for me. But then I realised my stupid mistake. I forgot to change Code signing identity to iOS Distribution from iOS Developer, under build settings tab. Please make sure you have selected 'iOS Distribution' there.

You can have read.table or read.csv do this conversion for you semi-automatically. First create a new class definition, then create a conversion function and set it as an "as" method using the setAs function like so:

setClass("num.with.commas")
setAs("character", "num.with.commas", 
        function(from) as.numeric(gsub(",", "", from) ) )

Then run read.csv like:

DF <- read.csv('your.file.here', 
   colClasses=c('num.with.commas','factor','character','numeric','num.with.commas'))

Using ElementTree:

import xml.etree.ElementTree

# Open original file
et = xml.etree.ElementTree.parse('file.xml')

# Append new tag: <a x='1' y='abc'>body text</a>
new_tag = xml.etree.ElementTree.SubElement(et.getroot(), 'a')
new_tag.text = 'body text'
new_tag.attrib['x'] = '1' # must be str; cannot be an int
new_tag.attrib['y'] = 'abc'

# Write back to file
#et.write('file.xml')
et.write('file_new.xml')

note: output written to file_new.xml for you to experiment, writing back to file.xml will replace the old content.

IMPORTANT: the ElementTree library stores attributes in a dict, as such, the order in which these attributes are listed in the xml text will NOT be preserved. Instead, they will be output in alphabetical order. (also, comments are removed. I'm finding this rather annoying)

ie: the xml input text <b y='xxx' x='2'>some body</b> will be output as <b x='2' y='xxx'>some body</b>(after alphabetising the order parameters are defined)

This means when committing the original, and changed files to a revision control system (such as SVN, CSV, ClearCase, etc), a diff between the 2 files may not look pretty.

There are several ways to exit Vim and have everything the same when you return. There is very good documentation within Vim itself explaining the various ways this can be done. You can use the following command within vim to access the relevant help page: :help usr_21

To give you a brief summary, here are the different methods of quitting and returning with your session intact:

1. Suspend and resume - You don't actually quit Vim with this; you simply hide your session in the background until you need it. If you reset your computer or issue a kill command to Vim, you will lose your session. This is good for when you want to switch to another task temporarily, but if this is the case, then you might want to look into using the GNU Screen utility instead.

2. Sessions - This is the true way of saving your session between instances of Vim. Even if you truly quit Vim, your session will be there for you when you return. This is probably what you are looking for.

String str = new String("SOME")

always create a new object on the heap

String str="SOME" 

uses the String pool

Try this small example:

        String s1 = new String("hello");
        String s2 = "hello";
        String s3 = "hello";

        System.err.println(s1 == s2);
        System.err.println(s2 == s3);

To avoid creating unnecesary objects on the heap use the second form.

[request setValue:@"application/zip" forHTTPHeaderField:@"Content-Type"];

The search query model lives in the scope defined by the ng-controller="whatever" directive. So if you want to bind the query model to <title>, you have to move the ngController declaration to an HTML element that is a common parent to both the body and title elements:

<html ng-app="phonecatApp" ng-controller="PhoneListCtrl">

In controller:

function innerItem($scope, $element){
    var jQueryInnerItem = $($element); 
}

Just an FYI for people who might have the same problem -- I just had to make my server send back the JSON as application/json and the default jQuery handler worked fine.

Add your library folder in your root location of your project and copy all the library files there. For ex YourProject/library then sync it and rest things seems OK to me.

jQuery 1.6+

To change the disabled property you should use the .prop() function.

$("input").prop('disabled', true);
$("input").prop('disabled', false);

jQuery 1.5 and below

The .prop() function doesn't exist, but .attr() does similar:

Set the disabled attribute.

$("input").attr('disabled','disabled');

To enable again, the proper method is to use .removeAttr()

$("input").removeAttr('disabled');

In any version of jQuery

You can always rely on the actual DOM object and is probably a little faster than the other two options if you are only dealing with one element:

// assuming an event handler thus 'this'
this.disabled = true;

The advantage to using the .prop() or .attr() methods is that you can set the property for a bunch of selected items.

Note: In 1.6 there is a .removeProp() method that sounds a lot like removeAttr(), but it SHOULD NOT BE USED on native properties like 'disabled' Excerpt from the documentation:

Note: Do not use this method to remove native properties such as checked, disabled, or selected. This will remove the property completely and, once removed, cannot be added again to element. Use .prop() to set these properties to false instead.

In fact, I doubt there are many legitimate uses for this method, boolean props are done in such a way that you should set them to false instead of "removing" them like their "attribute" counterparts in 1.5

You can use base_path() to get the base of your application - and then just add your public folder to that:

$path = base_path().'/public';
return File::put($path , $data)

Note: Be very careful about allowing people to upload files into your root of public_html. If they upload their own index.php file, they will take over your site.

The & means that the function accepts the address (or reference) to a variable, instead of the value of the variable.

For example, note the difference between this:

void af(int& g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

And this (without the &):

void af(int g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

I followed @josh3737 and installed the latest MSI from the node.js homepage.

But I had the additional problem that I still had the old node and npm on the command line. The problem was caused by the new installation, that it was installed into

C:\Program Files (x86)\nodejs\

instead of the previous installation in

C:\Program Files\nodejs\

The new installation added the new directory into my path variable after the old one. So the old installation was still the active one in the path. After removing C:\Program Files\nodejs\ from system path and C:\Users\...\AppData\Roaming\npm from user path and restarting the command line the new installation was active.

Maybe the least path was a local problem that has nothing to do with the new installation, I had two links to AppData\Roaming\npm in it. And maybe this can also be fixed by first uninstalling node.js and installing the new version afterwards.

You can wrap your TextInput in View.

<View>_x000D_
  <TextInput/>_x000D_
  <Icon/>_x000D_
<View>

and dynamically calculate width, if you want add an icon,

iconWidth = 0.05*viewWidth 
textInputWidth = 0.95*viewWidth

otherwise textInputwWidth = viewWidth.

View and TextInput background color are both white. (Small hack)

If you want to do the shortcut way :) :

','.join([str(word) for word in wordList])

But if you want to show off with logic :) :

wordList = ['USD', 'EUR', 'JPY', 'NZD', 'CHF', 'CAD']
stringText = ''

for word in wordList:
    stringText += word + ','

stringText = stringText[:-2]   # get rid of last comma
print(stringText)

select Id, StartDate,
Case IsNull (StartDate , '01/01/1800')
When '01/01/1800' then
  'Awaiting'
Else
  'Approved'
END AS StartDateStatus

Another valid option is to spread the joins across multiple LINQ clauses, as follows:

public static IEnumerable<Announcementboard> GetSiteContent(string pageName, DateTime date)
{
    IEnumerable<Announcementboard> content = null;
    IEnumerable<Announcementboard> addMoreContent = null;
        try
        {
            content = from c in DB.Announcementboards
              // Can be displayed beginning on this date
              where c.Displayondate > date.AddDays(-1)
              // Doesn't Expire or Expires at future date
              && (c.Displaythrudate == null || c.Displaythrudate > date)
              // Content is NOT draft, and IS published
              && c.Isdraft == "N" && c.Publishedon != null
              orderby c.Sortorder ascending, c.Heading ascending
              select c;

            // Get the content specific to page names
            if (!string.IsNullOrEmpty(pageName))
            {
              addMoreContent = from c in content
                  join p in DB.Announceonpages on c.Announcementid equals p.Announcementid
                  join s in DB.Apppagenames on p.Apppagenameid equals s.Apppagenameid
                  where s.Apppageref.ToLower() == pageName.ToLower()
                  select c;
            }

            // Add the specified content using UNION
            content = content.Union(addMoreContent);

            // Exclude the duplicates using DISTINCT
            content = content.Distinct();

            return content;
        }
    catch (MyLovelyException ex)
    {
        // Add your exception handling here
        throw ex;
    }
}

Selected Answer is not good.

Use pointer-events CSS style. (As Rashad Annara suggested)

See MDN https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events. Its supported in most browsers.

Simple adding "disabled" attribute to anchor will do the job if you have global CSS rule like following:

a[disabled], a[disabled]:hover {
   pointer-events: none;
   color: #e1e1e1;
}

In my system its the \ key. it's used for commands so that you can combine it with other chars.

You can find something about this in the Adobe Developer FAQ. (It's a PDF document rather than a web page, which I guess is unsurprising in this particular case.)

The FAQ notes that the use of the command line switches is unsupported.

To open a file it's:

AcroRd32.exe <filename>

The following switches are available:

• /n - Launch a new instance of Reader even if one is already open
• /s - Don't show the splash screen
• /o - Don't show the open file dialog
• /h - Open as a minimized window
• /p <filename> - Open and go straight to the print dialog
• /t <filename> <printername> <drivername> <portname> - Print the file the specified printer.

Based on @Alex Cory's answer:

[ "$(git rev-parse --is-inside-work-tree 2>/dev/null)" == "true" ]

doesn't contain any redundant operations and works in -e mode.

• As @go2null noted, this will not work in a bare repo. If you want to work with a bare repo for whatever reason, you can just check for git rev-parse succeeding, ignoring its output.
  • I don't consider this a drawback because the above line is indended for scripting, and virtually all git commands are only valid inside a worktree. So for scripting purposes, you're most likely interested in being not just inside a "git repo" but inside a worktree.

Have you tried rake reklamer:iqmedier ?

My custom rake tasks are in the lib directory, not in lib/tasks. Not sure if that matters.

Try this. Oracle has this feature to distinguish the millennium years..

As you mentioned, if your column is a varchar, then the below query will yield you 1989..

select to_date(column_name,'dd/mm/rr') from table1;

When the format rr is used in year, the following would be done by oracle.

if rr->00 to 49 ---> result will be 2000 - 2049, if rr->50 to 99 ---> result will be 1950 - 1999

In my case I had the following warnings:

Could not resolve this reference. Could not locate the assembly "x". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.

No way to resolve conflict between "x, Version=1.0.0.248, Culture=neutral, PublicKeyToken=null" and "x". Choosing "x, Version=1.0.0.248

The path to the dll was correct in my .csproj file but I had it referenced twice and the second reference was with another version. Once I deleted the unnecessary reference, the warning disappeared.

You should consider passing the -P argument in invoking Gradle.

From Gradle Documentation :

--project-prop Sets a project property of the root project, for example -Pmyprop=myvalue. See Section 14.2, “Gradle properties and system properties”.

Considering this build.gradle

task printProp << {
    println customProp
}

Invoking Gradle -PcustomProp=myProp will give this output :

$ gradle -PcustomProp=myProp printProp
:printProp
myProp

BUILD SUCCESSFUL

Total time: 3.722 secs

This is the way I found to pass parameters.

Your second attempt failed primarily because you named the CTE same as the underlying table and made the CTE look as if it was a recursive CTE, because it essentially referenced itself. A recursive CTE must have a specific structure which requires the use of the UNION ALL set operator.

Instead, you could just have given the CTE a different name as well as added the target column to it:

With SomeName As
(
SELECT 
CODE_DEST,
ROW_NUMBER() OVER (ORDER BY [RS_NOM] DESC) AS RN
FROM DESTINATAIRE_TEMP
)
UPDATE SomeName SET CODE_DEST=RN

I have a single checkbox named chkDueDate and an HTML object with a click event as follows:

$('#chkDueDate').attr('checked', !$('#chkDueDate').is(':checked'));

Clicking the HTML object (in this case a <span>) toggles the checked property of the checkbox.

Change file type from tsx -> ts, jsx -> js

You can get this error if you are working on .tsx or .jsx file and you are just exporting styles etc and not jsx. In this case the error is solved by changing the file type to .ts or .js

In Oracle SQL Developer

ALTER TABLE car_details MODIFY torque VARCHAR(100);

Some comments:

1. Jet/ACE files are organized in data pages, which means there is a certain amount of slack space when your record boundaries are not aligned with your data pages.

2. Row-level locking will greatly reduce the number of possible records, since it forces one record per data page.

3. In Jet 4, the data page size was increased to 4KBs (from 2KBs in Jet 3.x). As Jet 4 was the first Jet version to support Unicode, this meant that you could store 1GB of double-byte data (i.e., 1,000,000,000 double-byte characters), and with Unicode compression turned on, 2GBs of data. So, the number of records is going to be affected by whether or not you have Unicode compression on.

4. Since we don't know how much room in a Jet/ACE file is taken up by headers and other metadata, nor precisely how much room index storage takes, the theoretical calculation is always going to be under what is practical.

5. To get the most efficient possible storage, you'd want to use code to create your database rather than the Access UI, because Access creates certain properties that pure Jet does not need. This is not to say there are a lot of these, as properties set to the Access defaults are usually not set at all (the property is created only when you change it from the default value -- this can be seen by cycling through a field's properties collection, i.e., many of the properties listed for a field in the Access table designer are not there in the properties collection because they haven't been set), but you might want to limit yourself to Jet-specific data types (hyperlink fields are Access-only, for instance).

I just wasted an hour mucking around with this using Rnd() to populate 4 fields defined as type byte, with composite PK on the four fields, and it took forever to append enough records to get up to any significant portion of 2GBs. At over 2 million records, the file was under 80MBs. I finally quit after reaching just 700K 7 MILLION records and the file compacted to 184MBs. The amount of time it would take to get up near 2GBs is just more than I'm willing to invest!

If you're running cPanel/WHM, make sure that IP is whitelisted in the firewall. You will als need to add that IP to the remote SQL IP list in the cPanel account you're trying to connect to.

To change the end address property edit your wsdl file

The shape is a tuple. If there is only 1 dimension the shape will be one number and just blank after a comma. For 2+ dimensions, there will be a number after all the commas.

# 1 dimension with 2 elements, shape = (2,). 
# Note there's nothing after the comma.
z=np.array([  # start dimension
    10,       # not a dimension
    20        # not a dimension
])            # end dimension
print(z.shape)

(2,)

# 2 dimensions, each with 1 element, shape = (2,1)
w=np.array([  # start outer dimension 
    [10],     # element is in an inner dimension
    [20]      # element is in an inner dimension
])            # end outer dimension
print(w.shape)

See below code. I am using that and it is opening my HomeActivity.

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);

Here simple interceptor example, I set mouse on wait when ajax starts and set it to auto when ajax ends.

$httpProvider.interceptors.push(function($document) {
return {
 'request': function(config) {
     // here ajax start
     // here we can for example add some class or show somethin
     $document.find("body").css("cursor","wait");

     return config;
  },

  'response': function(response) {
     // here ajax ends
     //here we should remove classes added on request start

     $document.find("body").css("cursor","auto");

     return response;
  }
};
});

Code has to be added in application config app.config. I showed how to change mouse on loading state but in there it is possible to show/hide any loader content, or add, remove some css classes which are showing the loader.

Interceptor will run on every ajax call, so no need to create special boolean variables ( $scope.loading=true/false etc. ) on every http call.

Interceptor is using builded in angular jqLite https://docs.angularjs.org/api/ng/function/angular.element so no Jquery needed.

I believe enum have a .name() in its API, pretty simple to use like this example:

private int security;
public String security(){ return Security.values()[security].name(); }
public void setSecurity(int security){ this.security = security; }

    private enum Security {
            low,
            high
    }

With this you can simply call

yourObject.security() 

and it returns high/low as String, in this example

With Django version 1.3, the class based approach is:

from django.conf.urls.defaults import patterns, url
from django.views.generic import RedirectView

urlpatterns = patterns('',
    url(r'^some-url/$', RedirectView.as_view(url='/redirect-url/'), name='some_redirect'),
)

This example lives in in urls.py

The problem is that date takes your request quite literally and tries to use a date of 31st September (being 31st October minus one month) and then because that doesn't exist it moves to the next day which does. The date documentation (from info date) has the following advice:

The fuzz in units can cause problems with relative items. For example, `2003-07-31 -1 month' might evaluate to 2003-07-01, because 2003-06-31 is an invalid date. To determine the previous month more reliably, you can ask for the month before the 15th of the current month. For example:

 $ date -R
 Thu, 31 Jul 2003 13:02:39 -0700
 $ date --date='-1 month' +'Last month was %B?'
 Last month was July?
 $ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!'
 Last month was June!

I'm surprised that the answers here got so many upvotes when none of them really answer the question. Here's how to make sure that ONLY LATIN characters are in a given string.

const hasOnlyLetters = !!value.match(/^[a-z]*$/i);

The !! takes transforms something that's not boolean into a boolean value. (It's exactly the same as applying a ! twice, and in fact you can use as many ! as you'd like to toggle the truthiness multiple times.)

As for the RegEx, here's the breakdown.

• /.../i The delimiter is a / and the i means to assess the statement in a case-insensitive fashion.
• ^...$ The ^ means to look at the very beginning of a string. The $ means to look at the end of the string, and when used together, it means to consider the entire string. You can add more to the RegEx outside of these boundaries for things like appending/prepending a required suffix or prefix.
• [a-z]*This part says to look for all lowercase letters. (The case-insensitive modifier means that we don't need to look at uppercase letters, too.) The * at the end says that we should match whats in the brackets any number of times. That way "abc" will match instead of just "a" or "b", and so forth.

There is also a function in pandas called factorize which you can use to automatically do this type of work. It converts labels to numbers: ['male', 'female', 'male'] -> [0, 1, 0]. See this answer for more information.

System.GC.Collect() forces garbage collector to run. This is not recommended but can be used if situations arise.

No, sorry. User-defined functions in SQL Server are really limited, because of a requirement that they be deterministic. No way round it, as far as I know.

    return (*((uint8_t*)(&i))) == 0x67;
}

Having the following XML:

<node>Text1<subnode/>text2</node> 

How do I select either the first or the second text node via XPath?

Use:

/node/text()

This selects all text-node children of the top element (named "node") of the XML document.

/node/text()[1]

This selects the first text-node child of the top element (named "node") of the XML document.

/node/text()[2]

This selects the second text-node child of the top element (named "node") of the XML document.

/node/text()[someInteger]

This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:

/node/text()[position() = someInteger]

You don't need to use setAttribute for that - This code works (IE8 also)

<div id="something" >Hello</div>
<script type="text/javascript" >
    (function() {
        document.getElementById("something").onclick = function() { 
            alert('hello'); 
        };
    })();
</script>

If you want a dynamically sized array, then you should make a list. Not only will you get the .Add() functionality, but as @frode-f explains, dynamic arrays are more memory efficient and a better practice anyway.

And it's so easy to use.

Instead of your array declaration, try this:

$outItems = New-Object System.Collections.Generic.List[System.Object]

Adding items is simple.

$outItems.Add(1)
$outItems.Add("hi")

And if you really want an array when you're done, there's a function for that too.

$outItems.ToArray()

You can also use the required module.

require('./componentName.css');
const React = require('react');

Try a simple way:

if($('input[readonly="readonly"]')){
   alert("foo");
}

EmEditor works quite well for me. It's shareware IIRC but doesn't stop working after the license expires..

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

Another info: If you want use a Route Constraint, imagine that you want force that parameter has int datatype, then you need use this syntax:

[Route("v1/location/**{deviceOrAppid:int?}**", Name = "AddNewLocation")]

The ? character is put always before the last } character

I'm not entirely sure of the general purpose of the function, but you could always do this:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

var retval = getMachine(color, qty);

I had a similar issue trying to deploy an ASP Web Application to IIS 8. To fix it I did as Matt and Leniel suggested above. But also had to configure the Authentication setting of my site to enable Anonymous Authentication. And that Worked for me.

It is not natively possible to run Android application under iOS (which powers iPhone, iPad, iPod, etc.)

This is because both runtime stacks use entirely different approaches. Android runs Dalvik (a "variant of Java") bytecode packaged in APK files while iOS runs Compiled (from Obj-C) code from IPA files. Excepting time/effort/money and litigations (!), there is nothing inherently preventing an Android implementation on Apple hardware, however.

It looks to package a small Dalvik VM with each application and targeted towards developers.

See iPhoDroid:

Looks to be a dual-boot solution for 2G/3G jailbroken devices. Very little information available, but there are some YouTube videos.

See iAndroid:

iAndroid is a new iOS application for jailbroken devices that simulates the Android operating system experience on the iPhone or iPod touch. While it’s still very far from completion, the project is taking shape.

I am not sure the approach(es) it uses to enable this: it could be emulation or just a simulation (e.g. "looks like"). The requirement of being jailbroken makes it sound like emulation might be used ..

See BlueStacks, per the Holo Dev's comment:

It looks to be an "Android App Player" for OS X (and Windows). However, afaik, it does not [currently] target iOS devices ..

YMMV

Do a git add -A from the top of the working copy, take a look at git status and/or git diff --cached to review what you're about to do, then git commit the result.

or

int selection = Integer.parseInt(scanner.nextLine());

"Bad style" is very subjective. If a certain conventions works for you and your team, I think that will qualify a bad/good style.

To answer your question: I use a leading underscore to mark private variables. I find it clear and I can scan through code fast and find out what's going on.

(I almost never use "this" though, except to prevent a name clash.)

You might want to have a look at joda time, which is a little easier to use than the java native date tools, and provides many common date patterns pre-built.

In response to comments, more detail:

To do this using Joda time, you need two DateTimeFormatters - one for your input format to parse your input and one for your output format to print your output. Your input format is an ISO standard format, so Joda time's ISODateTimeFormat class has a static method with a parser for it already: dateHourMinuteSecondMillis. Your output format isn't one they have a pre-built formatter for, so you'll have to make one yourself using DateTimeFormat. I think DateTimeFormat.forPattern("mm/dd/yyyy kk:mm:ss.SSS"); should do the trick. Once you have your two formatters, call the parseDateTime() method on the input format and the print method on the output format to get your result, as a string.

Putting it together should look something like this (warning, untested):

DateTimeFormatter input = ISODateTimeFormat.dateHourMinuteSecondMillis();
DateTimeFormatter output = DateTimeFormat.forPattern("mm/dd/yyyy kk:mm:ss.SSS");
String outputFormat = output.print( input.parseDate(inputFormat) );

grep '^[0-9]\{1,16\}' | wc -l

Gives the counts with exact match count with limit

I am using CentOS and had same problem.

I changed /usr/local/bin/composer to /usr/bin/composer and it worked.

Run below command :

curl -sS https://getcomposer.org/installer | php sudo mv composer.phar /usr/bin/composer

Verify Composer is installed or not

composer --version

This worked for me in Luna elementary OS

sudo apt-get install libxtst6:i386

Today we are going to learn about Common table expression that is a new feature which was introduced in SQL server 2005 and available in later versions as well.

Common table Expression :- Common table expression can be defined as a temporary result set or in other words its a substitute of views in SQL Server. Common table expression is only valid in the batch of statement where it was defined and cannot be used in other sessions.

Syntax of declaring CTE(Common table expression) :-

with [Name of CTE]
as
(
Body of common table expression
)

Lets take an example :-

CREATE TABLE Employee([EID] [int] IDENTITY(10,5) NOT NULL,[Name] [varchar](50) NULL)

insert into Employee(Name) values('Neeraj')
insert into Employee(Name) values('dheeraj')
insert into Employee(Name) values('shayam')
insert into Employee(Name) values('vikas')
insert into Employee(Name) values('raj')

CREATE TABLE DEPT(EID INT,DEPTNAME VARCHAR(100))
insert into dept values(10,'IT')
insert into dept values(15,'Finance')
insert into dept values(20,'Admin')
insert into dept values(25,'HR')
insert into dept values(10,'Payroll')

I have created two tables employee and Dept and inserted 5 rows in each table. Now I would like to join these tables and create a temporary result set to use it further.

With CTE_Example(EID,Name,DeptName)
as
(
select Employee.EID,Name,DeptName from Employee 
inner join DEPT on Employee.EID =DEPT.EID
)
select * from CTE_Example

Lets take each line of the statement one by one and understand.

To define CTE we write "with" clause, then we give a name to the table expression, here I have given name as "CTE_Example"

Then we write "As" and enclose our code in two brackets (---), we can join multiple tables in the enclosed brackets.

In the last line, I have used "Select * from CTE_Example" , we are referring the Common table expression in the last line of code, So we can say that Its like a view, where we are defining and using the view in a single batch and CTE is not stored in the database as an permanent object. But it behaves like a view. we can perform delete and update statement on CTE and that will have direct impact on the referenced table those are being used in CTE. Lets take an example to understand this fact.

With CTE_Example(EID,DeptName)
as
(
select EID,DeptName from DEPT 
)
delete from CTE_Example where EID=10 and DeptName ='Payroll'

In the above statement we are deleting a row from CTE_Example and it will delete the data from the referenced table "DEPT" that is being used in the CTE.

Another option besides awk is nl which allows for options -v for setting starting value and -n <lf,rf,rz> for left, right and right with leading zeros justified. You can also include -s for a field separator such as -s "," for comma separation between line numbers and your data.

In a Unix environment, this can be done as

cat <infile> | ...other stuff... | nl -v 0 -n rz

or simply

nl -v 0 -n rz <infile>

Example:

echo "Here 
are
some 
words" > words.txt

cat words.txt | nl -v 0 -n rz

Out:

000000      Here
000001      are
000002      some
000003      words

This works for me on windows

# some_file.py on mainApp/app2 
import sys
sys.path.insert(0, sys.path[0]+'\\app2')

import some_file

Start an Android Emulator (make sure that all supported APIs are included when you created the emulator, we needed to have the Google APIs for instance).

Then simply email yourself a link to the .apk file, and download it directly in the emulator, and click the downloaded file to install it.

I got this error because my AdonisJS server was not running before I ran the test. Running the server first fixed it.

In my case, I need to set the path of openssl.cnf file manually on the command using config option. So the command

openssl req -x509 -config "C:\Users\sk\Downloads\openssl-0.9.8k_X64\openssl.cnf" -newkey rsa:4096 -keyout key.pem -out cert.pem -nodes -days 900
