just use following code

c = np.matrix([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
matrix([[1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]])

Then it will give you

you can check shape and dimension of matrix by using following code

c.shape

c.ndim

Here is just another option you couold apply for ASP NET MVC.

Normally you shoud use BaseController class for each Controller class.

So inside of it's constructor method do following.

public class BaseController : Controller
{
        public BaseController()
        {
            // get the previous url and store it with view model
            ViewBag.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;
        }
}

And now in ANY view you can do like

<button class="btn btn-success mr-auto" onclick="  window.location.href = '@ViewBag.PreviousUrl'; " style="width:2.5em;"><i class="fa fa-angle-left"></i></button>

Enjoy!

check your build.gradle file and make sure that use apply plugin: 'com.android.application' istead of apply plugin: 'com.android.library'

it worked for me

In SQL Server Denali, you will be able to do something that approaches what you're looking for. But you still can't just pass any arbitrarily defined wacky date string and expect SQL Server to accommodate. Here is one example using something you posted in your own answer. The FORMAT() function and can also accept locales as an optional argument - it is based on .Net's format, so most if not all of the token formats you'd expect to see will be there.

DECLARE @d DATETIME = '2008-10-13 18:45:19';

-- returns Oct-13/2008 18:45:19:
SELECT FORMAT(@d, N'MMM-dd/yyyy HH:mm:ss');

-- returns NULL if the conversion fails:
SELECT TRY_PARSE(FORMAT(@d, N'MMM-dd/yyyy HH:mm:ss') AS DATETIME);

-- returns an error if the conversion fails:
SELECT PARSE(FORMAT(@d, N'MMM-dd/yyyy HH:mm:ss') AS DATETIME);

I strongly encourage you to take more control and sanitize your date inputs. The days of letting people type dates using whatever format they want into a freetext form field should be way behind us by now. If someone enters 8/9/2011 is that August 9th or September 8th? If you make them pick a date on a calendar control, then the app can control the format. No matter how much you try to predict your users' behavior, they'll always figure out a dumber way to enter a date that you didn't plan for.

Until Denali, though, I think that @Ovidiu has the best advice so far... this can be made fairly trivial by implementing your own CLR function. Then you can write a case/switch for as many wacky non-standard formats as you want.

UPDATE for @dhergert:

SELECT TRY_PARSE('10/15/2008 10:06:32 PM' AS DATETIME USING 'en-us');
SELECT TRY_PARSE('15/10/2008 10:06:32 PM' AS DATETIME USING 'en-gb');

Results:

2008-10-15 22:06:32.000
2008-10-15 22:06:32.000

You still need to have that other crucial piece of information first. You can't use native T-SQL to determine whether 6/9/2012 is June 9th or September 6th.

You can pass it as an environment variable like this. Generally Node is the host that it is running in. The hostname is defaulted to the host name of the node when it is created.

docker service create -e 'FOO={{.Node.Hostname}}' nginx  

Then you can do docker ps to get the process ID and look at the env

$ docker exec -it c81640b6d1f1 env                                                                                                                                    PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=c81640b6d1f1
TERM=xterm
FOO=docker-desktop
NGINX_VERSION=1.17.4
NJS_VERSION=0.3.5
PKG_RELEASE=1~buster
HOME=/root

An example of usage would be with metricbeats so you know which node is having system issues which I put in https://github.com/trajano/elk-swarm:

  metricbeat:
    image: docker.elastic.co/beats/metricbeat:7.4.0
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /sys/fs/cgroup:/hostfs/sys/fs/cgroup:ro
      - /proc:/hostfs/proc:ro
      - /:/hostfs:ro
    user: root
    hostname: "{{.Node.Hostname}}"
    command:
      - -E
      - |
        metricbeat.modules=[
          {
            module:docker,
            hosts:[unix:///var/run/docker.sock],
            period:10s,
            enabled:true
          }
        ] 
      - -E
      - processors={1:{add_docker_metadata:{host:unix:///var/run/docker.sock}}} 
      - -E
      - output.elasticsearch.enabled=false
      - -E
      - output.logstash.enabled=true
      - -E
      - output.logstash.hosts=["logstash:5044"]
    deploy:
      mode: global

Here's a shorter one:

(Get-ChildItem C:\MYDIRECTORY -Recurse).fullname > filename.txt

It might be, because your span element sets is side as width as its content. if you have a div with 500px width and text-align center, and you enter a span tag it should be aligned in the center. So your problem might be a CSS one. Install Firebug at Firefox and check the style attributes your span or div object has.

You can avoid the repetition with an attribute test instead:

a/b/*[local-name()='c' or local-name()='d' or local-name()='e']

Contrary to Dimitre's antagonistic opinion, the above is not incorrect in a vacuum where the OP has not specified the interaction with namespaces. The self:: axis is namespace restrictive, local-name() is not. If the OP's intention is to capture c|d|e regardless of namespace (which I'd suggest is even a likely scenario given the OR nature of the problem) then it is "another answer that still has some positive votes" which is incorrect.

You can't be definitive without definition, though I'm quite happy to delete my answer as genuinely incorrect if the OP clarifies his question such that I am incorrect.

The latter is preferred, because it will handle subclasses properly. In fact, your example can be written even more easily because isinstance()'s second parameter may be a tuple:

if isinstance(b, (str, unicode)):
    do_something_else()

or, using the basestring abstract class:

if isinstance(b, basestring):
    do_something_else()

Since you're using SQL 2008:

UPDATE
    table_Name

SET
    column_A  
     = CASE
        WHEN @flag = '1' THEN @new_value
        ELSE 0
    END + column_A,

    column_B  
     = CASE
        WHEN @flag = '0' THEN @new_value
        ELSE 0
    END + column_B 
WHERE
    ID = @ID

If you were using SQL 2012:

UPDATE
    table_Name
SET
    column_A  = column_A + IIF(@flag = '1', @new_value, 0),
    column_B  = column_B + IIF(@flag = '0', @new_value, 0)
WHERE
    ID = @ID

Typically for dynamic lists of items, you use a std::vector.

Generally I use memset or a loop for raw memory dynamic allocation, depending on how variable I anticipate that area of code to be in the future.

HTML:

<div class="form-group">
  <label for="pt_date" class="col-2 col-form-label">Date</label>
  <input class="form-control" type="date" value=<?php echo  date("Y-m-d") ;?> id="pt_date" name="pt_date">
</div>

SQL

$pt_date = $_POST['pt_date'];

$sql = "INSERT INTO `table` ( `pt_date`) VALUES ( '$pt_date')";

Try this:

    @Repository
    @Qualifier("birthdayRepository")
    public interface BirthdayRepository extends MongoRepository<BirthDay,String> {
        public BirthDay findByFirstName(String firstName);
    }

And when injecting the bean:

    @Autowired
    @Qualifier("birthdayRepository")
    private BirthdayRepository repository;

If not, check your CoponentScan in your config.

When making join(t) function for both non-daemon thread and daemon thread, the main thread (or main process) should wait t seconds, then can go further to work on its own process. During the t seconds waiting time, both of the children threads should do what they can do, such as printing out some text. After the t seconds, if non-daemon thread still didn't finish its job, and it still can finish it after the main process finishes its job, but for daemon thread, it just missed its opportunity window. However, it will eventually die after the python program exits. Please correct me if there is something wrong.

OK - so this issue has been driving me crazy - v 6.3.6 on Ubuntu Linux. None of the above solutions worked for me. Connecting to localhost mysql server previously always worked fine. Connecting to remote server always timed out - after about 60 seconds, sometimes after less time, sometimes more.

What finally worked for me was upgrading Workbench to 6.3.9 - no more dropped connections.

npm init

to create the package.json file and then you use

ls node_modules/ | xargs npm install --save

to fill in the modules you have in the node_modules folder.

Edit: @paldepind pointed out that the second command is redundant because npm init now automatically adds what you have in your node_modules/ folder. I don't know if this has always been the case, but now at least, it works without the second command.

first of all you need to go in your ssh directory
for this type following command in your terminal in mac or whatever you use in window

cd ~/.ssh

now it is in the ssh
here you can find all you ssh key/files related to your all projects. now, type the following command to show you if any ssh key available

ls

this will show you all available ssh, in my case there were two
now, you will need to start an agent to add a ssh in it. For this type following command

eval "$(ssh-agent -s)"

now last but not least you will add a ssh in this agent type following command

ssh-add ~/.ssh/your-ssh

replace

replace your-ssh with your ssh file name which you got a list form second step ls command

to add parameter to post urls (to perma-links), i use this:

add_filter( 'post_type_link', 'append_query_string', 10, 2 );
function append_query_string( $url, $post ) 
{
    return add_query_arg('my_pid',$post->ID, $url);
}

output:

http://yoursite.com/pagename?my_pid=12345678

Don't do it inside the loop. Make a list, then combine them outside the loop.

datalist = list()

for (i in 1:5) {
    # ... make some data
    dat <- data.frame(x = rnorm(10), y = runif(10))
    dat$i <- i  # maybe you want to keep track of which iteration produced it?
    datalist[[i]] <- dat # add it to your list
}

big_data = do.call(rbind, datalist)
# or big_data <- dplyr::bind_rows(datalist)
# or big_data <- data.table::rbindlist(datalist)

This is a much more R-like way to do things. It can also be substantially faster, especially if you use dplyr::bind_rows or data.table::rbindlist for the final combining of data frames.

Just tried the stored procedure script. Seems the problem is the ' marks around the delimiters. The MySQL Docs show that delimiter characters do not need the single quotes.

So you want:

delimiter //

Instead of:

delimiter '//'

Works for me :)

Description OF Solution : Eclipse IDE can be used for this by creating a sample java project and add all jars in the Project Build path

STEPS below:

1. Create a sample Eclipse Java project.

2. All all the jars you have in its Build Path

3. CTRL+SHIFT+T and Type the full class name .

4. Results will be displayed in the window with all the jars having that class. See attached picture .

Assuming you are using Python 3.x:

print(*myList, sep='\n')

You can get the same behavior on Python 2.x using from __future__ import print_function, as noted by mgilson in comments.

With the print statement on Python 2.x you will need iteration of some kind, regarding your question about print(p) for p in myList not working, you can just use the following which does the same thing and is still one line:

for p in myList: print p

For a solution that uses '\n'.join(), I prefer list comprehensions and generators over map() so I would probably use the following:

print '\n'.join(str(p) for p in myList) 

If you are in a domain environment, you can also use:

winrs -r:PCNAME cmd

This will open a remote command shell.

If you are using node.js, console.log() takes format string as a first parameter:

 console.log('count: %d', count);

Apart from syntactic sugar, a reference is a const pointer (not pointer to a const). You must establish what it refers to when you declare the reference variable, and you cannot change it later.

Update: now that I think about it some more, there is an important difference.

A const pointer's target can be replaced by taking its address and using a const cast.

A reference's target cannot be replaced in any way short of UB.

This should permit the compiler to do more optimization on a reference.

One issue is that reindex will fail if there are duplicate values. Say we're working with timestamped data, which we want to index by date:

df = pd.DataFrame({
    'timestamps': pd.to_datetime(
        ['2016-11-15 1:00','2016-11-16 2:00','2016-11-16 3:00','2016-11-18 4:00']),
    'values':['a','b','c','d']})
df.index = pd.DatetimeIndex(df['timestamps']).floor('D')
df

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-18  "2016-11-18 04:00:00"  d

Due to the duplicate 2016-11-16 date, an attempt to reindex:

all_days = pd.date_range(df.index.min(), df.index.max(), freq='D')
df.reindex(all_days)

fails with:

...
ValueError: cannot reindex from a duplicate axis

(by this it means the index has duplicates, not that it is itself a dup)

Instead, we can use .loc to look up entries for all dates in range:

df.loc[all_days]

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-17  NaN                    NaN
2016-11-18  "2016-11-18 04:00:00"  d

fillna can be used on the column series to fill blanks if needed.

To expand on BalusC's answer, any scenario where the sender continues to write after the peer has stopped reading and closed its socket will produce this exception, as will the peer closing while it still had unread data in its own socket receive buffer. In other words, an application protocol error. For example, if you write something to the peer that the peer doesn't understand, and then it closes its socket in protest, and you then continue to write, the peer's TCP stack will issue an RST, which results in this exception and message at the sender.

The syntax is

EXEC mySchema.myPackage.myProcedure@myRemoteDB( 'someParameter' );

To add on to what Egon said, simply create your blob called "folder/1.txt", and it will work. No need to create a directory.

get ID of ImageView as

ImageView imgFp = (ImageView) findViewById(R.id.imgFp);

then Use

imgFp.setImageResource(R.drawable.fpscan);

to set source image programatically instead from XML.

Simple and elegant solution for BootStrap 3.x. The same modal can be reused in this way.

$("#myModal").modal("hide");
$('#myModal').on('hidden.bs.modal', function (e) {
   $("#myModal").html(data);
   $("#myModal").modal();
   // do something more...
}); 

First execute this

sudo apt-get install gcc binutils make linux-source

Then run again

/usr/bin/vmware-config-tools.pl

This is all you need to do. Now your system has the gcc make and the linux kernel sources.

If you add the following you can set the background colour or image (your css)

 html { 
     background-image: url('http://yoursite/i/tile.jpg');
     background-repeat: repeat; 
 }

 .body {
     background-color: transparent; 
 }

This is because BS applies a css rule for background colour and also for the .container class.

Simple way to catch all scroll events (touch and wheel)

window.onscroll = function(e) {
  // print "false" if direction is down and "true" if up
  console.log(this.oldScroll > this.scrollY);
  this.oldScroll = this.scrollY;
}

If your server have a http service you can compress your directory and download the compressed file.

Compress:

tar -zcvf archive-name.tar.gz -C directory-name .

Download throught your browser:

http://the-server-ip/archive-name.tar.gz

If you don't have direct access to the server ip, do a ssh tunnel throught putty, and forward the 80 port in some local port, and you can download the file.

The accepted answer gave two locations:

here

C:\Documents and Settings\Administrator\Local Settings\Temp\VWDWebCache

and possibly here

C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\WebsiteCache

Did you try those?

Edited to add

On my Windows Vista machine, it's located in

%Temp%\VWDWebCache

and in

%LocalAppData%\Microsoft\WebsiteCache

From your additional information (regarding team edition) this comes from Clear Client TFS Cache:

Clear Client TFS Cache

Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

To solve it..

For Windows Vista delete contents of this folder

%LocalAppData%\Microsoft\Team Foundation\1.0\Cache

I ran into this using networkx and bokeh

This works for me in Windows 7 (taken from here):

1. To create a jupyter_notebook_config.py file, with all the defaults commented out, you can use the following command line:

   $ jupyter notebook --generate-config

2. Open the file and search for c.NotebookApp.iopub_data_rate_limit

3. Comment out the line c.NotebookApp.iopub_data_rate_limit = 1000000 and change it to a higher default rate. l used c.NotebookApp.iopub_data_rate_limit = 10000000

This unforgiving default config is popping up in a lot of places. See git issues:

• jupyter

• IOPub data rate exceeded

It looks like it might get resolved with the 5.1 release

Update:

Jupyter notebook is now on release 5.2.2. This problem should have been resolved. Upgrade using conda or pip.

begin() returns the first pair, (precisely, an iterator to the first pair, and you can access the key/value as ->first and ->second of that iterator)

For TF2.x, you can do like this.

import tensorflow as tf
with tf.compat.v1.Session() as sess:
    hello = tf.constant('hello world')
    print(sess.run(hello))

>>> b'hello world

It can done simply by using the Builder's setView(). You can create any view of your choice and feed into the builder. This works good. I use a custom TextView that is rendered by the dialog builder. I dont set the message and this space is utilized to render my custome textview.

Create a table layout panel with two columns in your form and name it tlpFields.

Then, simply add new control to table layout panel (in this case I added 5 labels in column-1 and 5 textboxes in column-2).

tlpFields.RowStyles.Clear();  //first you must clear rowStyles

for (int ii = 0; ii < 5; ii++)
{
    Label l1= new Label();
    TextBox t1 = new TextBox();

    l1.Text = "field : ";

    tlpFields.Controls.Add(l1, 0, ii);  // add label in column0
    tlpFields.Controls.Add(t1, 1, ii);  // add textbox in column1

    tlpFields.RowStyles.Add(new RowStyle(SizeType.Absolute,30)); // 30 is the rows space
}

Finally, run the code.

Use the Python set type. That would be the most Pythonic. :)

Also, since it's native, it should be the most optimized method too.

See:

http://docs.python.org/library/stdtypes.html#set

http://docs.python.org/library/sets.htm (for older python)

# Using Python 2.7 set literal format.
# Otherwise, use: l1 = set([1,2,6,8])
#
l1 = {1,2,6,8}
l2 = {2,3,5,8}
l3 = l1 - l2

Use following command instead of npm install

npm ci

python -c "from datetime import datetime; print str(datetime.now())[:-3]"

If you want to execute multiple commands in a for loop, you can save the result of find with mapfile (bash >= 4) as an variable and go through the array with ${dirlist[@]}. It also works with directories containing spaces.

The find command is based on the answer by Boldewyn. Further information about the find command can be found there.

IFS=""
mapfile -t dirlist < <( find . -maxdepth 1 -mindepth 1 -type d -printf '%f\n' )
for dir in ${dirlist[@]}; do
    echo ">${dir}<"
    # more commands can go here ...
done

This was my workaround:

$('#vcGoButton').click(function () {
    var buttonStatus = $('#vcChangeLocation').prop('checked');
    console.log("Status is " + buttonStatus);
    if (buttonStatus) {
        var address = $('#vcNewLocation').val();
        var cabNumber = $('#vcVehicleNumber').val();
        $.get('postCabLocation.php',
              {address: address, cabNumber: cabNumber},
              function(data) {
                  console.log("Changed vehicle " + cabNumber + " location to " + address );
              });
    }
    else {
        console.log("VC go button clicked, but no location action");
    }
});

A few years ago it was said that update() and digest() were legacy methods and the new streaming API approach was introduced. Now the docs say that either method can be used. For example:

var crypto    = require('crypto');
var text      = 'I love cupcakes';
var secret    = 'abcdeg'; //make this your secret!!
var algorithm = 'sha1';   //consider using sha256
var hash, hmac;

// Method 1 - Writing to a stream
hmac = crypto.createHmac(algorithm, secret);    
hmac.write(text); // write in to the stream
hmac.end();       // can't read from the stream until you call end()
hash = hmac.read().toString('hex');    // read out hmac digest
console.log("Method 1: ", hash);

// Method 2 - Using update and digest:
hmac = crypto.createHmac(algorithm, secret);
hmac.update(text);
hash = hmac.digest('hex');
console.log("Method 2: ", hash);

Tested on node v6.2.2 and v7.7.2

See https://nodejs.org/api/crypto.html#crypto_class_hmac. Gives more examples for using the streaming approach.

In C, a string, as you know, is a character pointer (char *). If you want to swap two strings, you're swapping two char pointers, i.e. just two addresses. In order to do any swap in a function, you need to give it the addresses of the two things you're swapping. So in the case of swapping two pointers, you need a pointer to a pointer. Much like to swap an int, you just need a pointer to an int.

The reason your last code snippet doesn't work is because you're expecting it to swap two char pointers -- it's actually written to swap two characters!

Edit: In your example above, you're trying to swap two int pointers incorrectly, as R. Martinho Fernandes points out. That will swap the two ints, if you had:

int a, b;
intSwap(&a, &b);

LocalDate from java.time

Use LocalDate from java.time, the modern Java date and time API, for a date

    DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MMMM d, u", Locale.ENGLISH);
    LocalDate date = LocalDate.parse("June 27, 2007", dateFormatter);
    System.out.println(date);

Output:

2007-06-27

As others have said already, remember to specify an English-speaking locale when your string is in English. A LocalDate is a date without time of day, so a lot better suitable for the date from your string than the old Date class. Despite its name a Date does not represent a date but a point in time that falls on at least two different dates in different time zones of the world.

Only if you need an old-fashioned Date for an API that you cannot afford to upgrade to java.time just now, convert like this:

    Instant startOfDay = date.atStartOfDay(ZoneId.systemDefault()).toInstant();
    Date oldfashionedDate = Date.from(startOfDay);
    System.out.println(oldfashionedDate);

Output in my time zone:

Wed Jun 27 00:00:00 CEST 2007

For business data, if the data is private I would use a secured connection, otherwise a forms authentication is sufficient.

If you do decide to use a secured connection, please note that I do not have experience with securing websites, I am just recanting off what I encountered during my own personal experience. If I am wrong in anyway, please feel free to correct me.

What should I do to prepare my website for https. (Do I need to alter the code / Config)

In order to enable SSL (Secure Sockets Layer) for your website, you would need to set-up a certificate, code or config is not altered.

I have enabled SSL for an internal web-server, by using OpenSSL and ActivePerl from this online tutorial. If this is used for a larger audience (my audience was less than 10 people) and is in the public domain, I suggest seeking professional alternatives.

Is SSL and https one and the same...

Not exactly, but they go hand in hand! SSL ensures that data is encrypted and decrypted back and forth while you are viewing the website, https is the URI that is need to access the secure website. You will notice when you try to access http://secure.mydomain.com it displays an error message.

Do I need to apply with someone to get some license or something.

You would not need to obtain a license, but rather a certificate. You can look into companies that offer professional services with securing websites, such as VeriSign as an example.

Do I need to make all my pages secured or only the login page...

Once your certificate is enabled for mydomain.com every page that falls under *.mydomain.com will be secured.

SHIFT + TAB works

You are importing the module datetime, which doesn't have a strptime function.

That module does have a datetime object with that method though:

import datetime
dtDate = datetime.datetime.strptime(sDate, "%m/%d/%Y")

Alternatively you can import the datetime object from the module:

from datetime import datetime
dtDate = datetime.strptime(sDate, "%m/%d/%Y")

Note that the strptime method was added in python 2.5; if you are using an older version use the following code instead:

import datetime, time
dtDate = datetime.datetime(*time.strptime(sDate, "%m/%d/%Y")[:6])

I created 2 servers, listening on same port 8081, running from same code, while learning

1st server creation shud have worked 2nd server creation failed with EADDRINUSE

node.js callback delays might be reason behind neither worked, or 2nd server creation had exception, and program exited, so 1st server is also closed

2 server issue hint, I got from: How to fix Error: listen EADDRINUSE while using nodejs?

The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

If you mean you want to open a new tab, try the below:

protected void Page_Load(object sender, EventArgs e)
{
    this.Form.Target = "_blank";
}

protected void Button1_Click(object sender, EventArgs e)
{

    Response.Redirect("Otherpage.aspx");
}

This will keep the original page to stay open and cause the redirects on the current page to affect the new tab only.

Obligatory Twisted example:

twistd -n ftp

And probably useful:

twistd ftp --help

Usage: twistd [options] ftp [options].
WARNING: This FTP server is probably INSECURE do not use it.
Options:
  -p, --port=           set the port number [default: 2121]
  -r, --root=           define the root of the ftp-site. [default:
                    /usr/local/ftp]
  --userAnonymous=  Name of the anonymous user. [default: anonymous]
  --password-file=  username:password-style credentials database
  --version         
  --help            Display this help and exit.

You can also use the following command:

echo toto; history -d $(history | sed -n '$s/\s*\([0-9]*\)\s*.*$/\1/p')

I think it's a very portable command.

For mysql you have limit, you can fire query as :

SELECT * FROM table limit 100` -- get 1st 100 records
SELECT * FROM table limit 100, 200` -- get 200 records beginning with row 101

For Oracle you can use rownum

See mysql select syntax and usage for limit here.

For SQLite, you have limit, offset. I haven't used SQLite but I checked it on SQLite Documentation. Check example for SQLite here.

QEMU has a fantastic utility called qmeu-img that will translate between all manner of disk image formats. An article on this process is at http://thedarkmaster.wordpress.com/2007/03/12/vmware-virtual-machine-to-virtual-box-conversion-how-to/

I recall in my head that I used qemu-img to roll multiple VMDKs into one, but I don't have that computer with me to retest the process. Even if I'm wrong, the article above includes a section that describes how to convert them with your VMWare tools.

Update

See my other SO answer.

var request = (HttpWebRequest)WebRequest.Create("https://example.com/endpoint");

From your stack trace, EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) occurred because dispatch_group_t was released while it was still locking (waiting for dispatch_group_leave).

According to what you found, this was what happened :

• dispatch_group_t group was created. group's retain count = 1.
• -[self webservice:onCompletion:] captured the group. group's retain count = 2.
• dispatch_async(...., ^{ dispatch_group_wait(group, ...) ... }); captured the group again. group's retain count = 3.
• Exit the current scope. group was released. group's retain count = 2.
• dispatch_group_leave was never called.
• dispatch_group_wait was timeout. The dispatch_async block was completed. group was released. group's retain count = 1.
• You called this method again. When -[self webservice:onCompletion:] was called again, the old onCompletion block was replaced with the new one. So, the old group was released. group's retain count = 0. group was deallocated. That resulted to EXC_BAD_INSTRUCTION.

To fix this, I suggest you should find out why -[self webservice:onCompletion:] didn't call onCompletion block, and fix it. Then make sure the next call to the method will happen after the previous call did finish.

In case you allow the method to be called many times whether the previous calls did finish or not, you might find someone to hold group for you :

• You can change the timeout from 2 seconds to DISPATCH_TIME_FOREVER or a reasonable amount of time that all -[self webservice:onCompletion] should call their onCompletion blocks by the time. So that the block in dispatch_async(...) will hold it for you.
  OR
• You can add group into a collection, such as NSMutableArray.

I think it is the best approach to create a dedicate class for this action. When you want to make calls to webservice, you then create an object of the class, call the method on it with the completion block passing to it that will release the object. In the class, there is an ivar of dispatch_group_t or dispatch_semaphore_t.

Yes! And another solution. My solution differs in the keys that are being checked. In all other solutions we only look at the keys in dict_b. But here we look in the union of both dictionaries.

Do with it as you please

def update_nested(dict_a, dict_b):
    set_keys = set(dict_a.keys()).union(set(dict_b.keys()))
    for k in set_keys:
        v = dict_a.get(k)
        if isinstance(v, dict):
            new_dict = dict_b.get(k, None)
            if new_dict:
                update_nested(v, new_dict)
        else:
            new_value = dict_b.get(k, None)
            if new_value:
                dict_a[k] = new_value

Based on the previous answers, here is another solution which returns the same result as df2.teams.apply(pd.Series) with a much faster run time:

pd.DataFrame([{x: y for x, y in enumerate(item)} for item in df2['teams'].values.tolist()], index=df2.index)

Timings:

import pandas as pd
d1 = {'teams': [['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],
                ['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG']]}
df2 = pd.DataFrame(d1)
df2 = pd.concat([df2]*1000).reset_index(drop=True)

In [2]: %timeit df2['teams'].apply(pd.Series)

For NetBeans to be able to interact with tomcat, it needs the user as setup in netbeans to be properly configured in the tomcat-users.xml file. NetBeans can do so automatically.

That is, within the tomcat-users.xml, which you can find in ${CATALINA_HOME}/conf, or ${CATALINA_BASE}/conf,

1. make sure that the user (as chosen in netbeans) is added the script-manager role

Example, change

<user password="tomcat" roles="manager,admin" username="tomcat"/>

To

<user password="tomcat" roles="manager-script,manager,admin" username="tomcat"/>

2. make sure that the manager-script role is declared

Add

<role rolename="manager-script"/>

Actually the netbeans online-help incorrectly states:

Username - Specifies the user name that the IDE uses to log into the server's manager application. The user must be associated with the manager role. The first time the IDE started the Tomcat Web Server, such as through the Start/Stop menu action or by executing a web component from the IDE, the IDE adds an admin user with a randomly-generated password to the tomcat-base-path/conf/tomcat-users.xml file. (Right-click the Tomcat Web server instance node in the Services window and select Properties. In the Properties dialog box, the Base Directory property points to the base-dir directory.) The admin user entry in the tomcat-users.xml file looks similar to the following: <user username="idea" password="woiehh" roles="manager"/>

The role should be manager-script, and not manager.

For a more complete tomcat-users.xml file:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="manager-script"/>
  <role rolename="manager-gui"/>
  <user password="tomcat" roles="manager-script" username="tomcat"/>
  <user password="pass" roles="manager-gui" username="me"/>
</tomcat-users>

There is another nice posting on why am I getting the deployment error?

Depending on your needs, you may also want to check out the classes CountDownLatch and CyclicBarrier in the java.util.concurrent package. They can be useful if you want your threads to wait for each other, or if you want more fine-grained control over the way your threads execute (e.g., waiting in their internal execution for another thread to set some state). You could also use a CountDownLatch to signal all of your threads to start at the same time, instead of starting them one by one as you iterate through your loop. The standard API docs have an example of this, plus using another CountDownLatch to wait for all threads to complete their execution.

The simple solution is to redirect to a new (if not the same) page. This pattern is very common in web applications, and is called Post/Redirect/Get. It's typical for all forms to do a POST, then if successful, you should do a redirect.

Try as much as possible to always separate (in different files) your view script (html mostly) from your controller script (business logic and stuff). In this way, you would always post data to a seperate controller script and then redirect back to a view script which when rendered, will contain no POST data in the request header.

You can use this method:

function string:split(delimiter)
  local result = { }
  local from  = 1
  local delim_from, delim_to = string.find( self, delimiter, from  )
  while delim_from do
    table.insert( result, string.sub( self, from , delim_from-1 ) )
    from  = delim_to + 1
    delim_from, delim_to = string.find( self, delimiter, from  )
  end
  table.insert( result, string.sub( self, from  ) )
  return result
end

delimiter = string.split(stringtodelimite,pattern) 

_{All standard references below refers to N4659: March 2017 post-Kona working draft/C++17 DIS.}

Typedef declarations can, whereas alias declarations cannot, be used as initialization statements

But, with the first two non-template examples, are there any other subtle differences in the standard?

• Differences in semantics: none.
• Differences in allowed contexts: some⁽¹⁾.

^{(1) In addition to the examples of alias templates, which has already been mentioned in the original post.}

Same semantics

As governed by [dcl.typedef]/2 [extract, emphasis mine]

[dcl.typedef]/2 A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. Such a typedef-name has the same semantics as if it were introduced by the typedef specifier. [...]

a typedef-name introduced by an alias-declaration has the same semantics as if it were introduced by the typedef declaration.

Subtle difference in allowed contexts

However, this does not imply that the two variations have the same restrictions with regard to the contexts in which they may be used. And indeed, albeit a corner case, a typedef declaration is an init-statement and may thus be used in contexts which allow initialization statements

// C++11 (C++03) (init. statement in for loop iteration statements).
for(typedef int Foo; Foo{} != 0;) {}

// C++17 (if and switch initialization statements).
if (typedef int Foo; true) { (void)Foo{}; }
//  ^^^^^^^^^^^^^^^ init-statement

switch(typedef int Foo; 0) { case 0: (void)Foo{}; }
//     ^^^^^^^^^^^^^^^ init-statement

// C++20 (range-based for loop initialization statements).
std::vector<int> v{1, 2, 3};
for(typedef int Foo; Foo f : v) { (void)f; }
//  ^^^^^^^^^^^^^^^ init-statement

for(typedef struct { int x; int y;} P;
//  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ init-statement
    auto [x, y] : {P{1, 1}, {1, 2}, {3, 5}}) { (void)x; (void)y; }

whereas an alias-declaration is not an init-statement, and thus may not be used in contexts which allows initialization statements

// C++ 11.
for(using Foo = int; Foo{} != 0;) {}
//  ^^^^^^^^^^^^^^^ error: expected expression

// C++17 (initialization expressions in switch and if statements).
if (using Foo = int; true) { (void)Foo{}; }
//  ^^^^^^^^^^^^^^^ error: expected expression

switch(using Foo = int; 0) { case 0: (void)Foo{}; }
//     ^^^^^^^^^^^^^^^ error: expected expression

// C++20 (range-based for loop initialization statements).
std::vector<int> v{1, 2, 3};
for(using Foo = int; Foo f : v) { (void)f; }
//  ^^^^^^^^^^^^^^^ error: expected expression

If you want to do it without any extra includes:

vector<IComponent*> myComponents; //assume it has items in it already.
void RemoveComponent(IComponent* componentToRemove)
{
    IComponent* juggler;

    if (componentToRemove != NULL)
    {
        for (int currComponentIndex = 0; currComponentIndex < myComponents.size(); currComponentIndex++)
        {
            if (componentToRemove == myComponents[currComponentIndex])
            {
                //Since we don't care about order, swap with the last element, then delete it.
                juggler = myComponents[currComponentIndex];
                myComponents[currComponentIndex] = myComponents[myComponents.size() - 1];
                myComponents[myComponents.size() - 1] = juggler;

                //Remove it from memory and let the vector know too.
                myComponents.pop_back();
                delete juggler;
            }
        }
    }
}

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

For SDK 29 :

String str1 = "";
folder1 = new File(String.valueOf(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES)));
if (folder1.exists()) {str1 = folder1.toString() + File.separator;}

public static void createTextFile(String sBody, String FileName, String Where) {
    try {
        File gpxfile = new File(Where, FileName);
        FileWriter writer = new FileWriter(gpxfile);
        writer.append(sBody);
        writer.flush();
        writer.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Then you can save your file like this :

createTextFile("This is Content","file.txt",str1);

Use get_the_category() like this:

<?php
foreach((get_the_category()) as $category) { 
    echo $category->cat_name . ' '; 
} 
?>

It returns a list because a post can have more than one category.

The documentation also explains how to do this from outside the loop.

Those GCD functions provided by Commons-Math and Guava have some differences.

• Commons-Math throws an ArithematicException.class only for Integer.MIN_VALUE or Long.MIN_VALUE.
  • Otherwise, handles the value as an absolute value.
• Guava throws an IllegalArgumentException.class for any negative values.

Take a look at the GeckoFX control.

GeckoFX is an open-source component which makes it easy to embed Mozilla Gecko (Firefox) into any .NET Windows Forms application. Written in clean, fully commented C#, GeckoFX is the perfect replacement for the default Internet Explorer-based WebBrowser control.

Sample application using Vue. Requires a backend server running on localhost to process the request:

var app = new Vue({
  el: "#app",
  data: {
    file: ''
  },
  methods: {
    submitFile() {
      let formData = new FormData();
      formData.append('file', this.file);
      console.log('>> formData >> ', formData);

      // You should have a server side REST API 
      axios.post('http://localhost:8080/restapi/fileupload',
          formData, {
            headers: {
              'Content-Type': 'multipart/form-data'
            }
          }
        ).then(function () {
          console.log('SUCCESS!!');
        })
        .catch(function () {
          console.log('FAILURE!!');
        });
    },
    handleFileUpload() {
      this.file = this.$refs.file.files[0];
      console.log('>>>> 1st element in files array >>>> ', this.file);
    }
  }
});

///UPDATED DEMO 2 WATCH SOLUTION////

I hope that is the solution you're looking for! DEMO1 DEMO2

With that solution the only scrollbar in the page is on your contents section in the middle! In that section build your structure with a sidebar or whatever you want!

You can do that with that code here:

<div class="navTop">
<h1>Title</h1>
    <nav>Dynamic menu</nav>
</div>
<div class="container">
    <section>THE CONTENTS GOES HERE</section>
</div>
<footer class="bottomFooter">
    Footer
</footer>

With that css:

.navTop{
width:100%;
border:1px solid black;
float:left;
}
.container{
width:100%;
float:left;
overflow:scroll;
}
.bottomFooter{
float:left;
border:1px solid black;
width:100%;
}

And a bit of jquery:

$(document).ready(function() {
  function setHeight() {
    var top = $('.navTop').outerHeight();
    var bottom = $('footer').outerHeight();
    var totHeight = $(window).height();
    $('section').css({ 
      'height': totHeight - top - bottom + 'px'
    });
  }

  $(window).on('resize', function() { setHeight(); });
  setHeight();
});

If you don't want jquery

<div class="row">
    <h1>Title</h1>
    <nav>NAV</nav>
</div>

<div class="row container">
    <div class="content">
        <div class="sidebar">
            SIDEBAR
        </div>
        <div class="contents">
            CONTENTS
        </div>
    </div>
    <footer>Footer</footer>
</div>

There is no format specifier for bool. You can print it using some of the existing specifiers for printing integral types or do something more fancy:

 printf("%s", x?"true":"false");

I found a solution that works for hiding the grid lines in a Line chart.

Set the gridLines color to be the same as the div's background color.

var options = {
    scales: {
        xAxes: [{
            gridLines: {
                color: "rgba(0, 0, 0, 0)",
            }
        }],
        yAxes: [{
            gridLines: {
                color: "rgba(0, 0, 0, 0)",
            }   
        }]
    }
}

or use

var options = {
    scales: {
        xAxes: [{
            gridLines: {
                display:false
            }
        }],
        yAxes: [{
            gridLines: {
                display:false
            }   
        }]
    }
}

if you are using webstorm just make sure your default port is not 3000 from file -> settings -> Build, Execution, Deployment -> Debugger And there change

Built-in server port

and set it to "63342" or see this answer Change WebStorm LiveEdit Port (63342)

I've had to do a verification of a letsencrypt certificate and I did it like this:

1. Download the root-cert and the intermediate-cert from the letsencrypt chain of trust.

2. Issue this command:

   $ openssl verify -CAfile letsencrypt-root-cert/isrgrootx1.pem.txt -untrusted letsencrypt-intermediate-cert/letsencryptauthorityx3.pem.txt /etc/letsencrypt/live/sitename.tld/cert.pem 
   /etc/letsencrypt/live/sitename.tld/cert.pem: OK
   

You can use this approach which truncates the time part:

select * from test
where convert(datetime,'03/19/2014',102) = DATEADD(dd, DATEDIFF(dd, 0, date), 0)

You can use this function to get the time (unfortunately it doesn't say AM or PM):

def gettime():
    from datetime import datetime
    return ((str(datetime.now())).split(' ')[1]).split('.')[0]

To get the hours, minutes, seconds and milliseconds to merge later, you can use these functions:

Hour:

def gethour():
    from datetime import datetime
    return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]

Minute:

def getminute():
    from datetime import datetime
    return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]

Second:

def getsecond():
    from datetime import datetime
    return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]

Millisecond:

def getmillisecond():
    from datetime import datetime
    return (str(datetime.now())).split('.')[1]

If you also want to get the name of the foreign key column:

SELECT i.TABLE_SCHEMA, i.TABLE_NAME, 
       i.CONSTRAINT_TYPE, i.CONSTRAINT_NAME, 
       k.COLUMN_NAME, k.REFERENCED_TABLE_NAME, k.REFERENCED_COLUMN_NAME 
  FROM information_schema.TABLE_CONSTRAINTS i 
  LEFT JOIN information_schema.KEY_COLUMN_USAGE k 
       ON i.CONSTRAINT_NAME = k.CONSTRAINT_NAME 
 WHERE i.TABLE_SCHEMA = '<TABLE_NAME>' AND i.CONSTRAINT_TYPE = 'FOREIGN KEY' 
 ORDER BY i.TABLE_NAME;

Open Console/Command line --> Go to your Jenkins installation directory. Execute the following commands respectively:

Although this is valid in HTML, you can't use an ID starting with an integer in CSS selectors.

As pointed out, you can use getElementById instead, but you can also still achieve the same with a querySelector:

document.querySelector("[id='22']")

You can define a generic function like this:

@SuppressWarnings("unchecked")
public static <T> List<T> newFixedSizeList(int size) {
    return (List<T>)Arrays.asList(new Object[size]);
}

And

List<String> s = newFixedSizeList(3);  // All elements are initialized to null
s.set(0, "zero");
s.add("three");  // throws java.lang.UnsupportedOperationException

Try

$('li.current_sub').prev('.par_cat').[do stuff];

In latin1 each character is exactly one byte long. In utf8 a character can consist of more than one byte. Consequently utf8 has more characters than latin1 (and the characters they do have in common aren't necessarily represented by the same byte/bytesequence).

As Peter Mortensen wrote:

In the Visual Studio 2005 menu:

Debug -> New Breakpoint -> New Data Breakpoint

Enter: &myVariable

Additional information:

Obviously, the system must know which address in memory to watch. So - set a normal breakpoint to the initialisation of myVariable (or myClass.m_Variable) - run the system and wait till it stops at that breakpoint. - Now the Menu entry is enabled, and you can watch the variable by entering &myVariable, or the instance by entering &myClass.m_Variable. Now the addresses are well defined.

Sorry when I did things wrong by explaining an already given solution. But I could not add a comment, and there has been some comments regarding this.

The solution given by Ash Clarke for subdomains works great, but please note that you need to include the document.domain = "mydomain.com"; in both the head of the iframe page and the head of the parent page, as stated in the link same origin policy checks

An important extension to the same origin policy implemented for JavaScript DOM access (but not for most of the other flavors of same-origin checks) is that two sites sharing a common top-level domain may opt to communicate despite failing the "same host" check by mutually setting their respective document.domain DOM property to the same qualified, right-hand fragment of their current host name. For example, if http://en.example.com/ and http://fr.example.com/ both set document.domain to "example.com", they would be from that point on considered same-origin for the purpose of DOM manipulation.

Or you can use reject method

$newColection = $collection->reject(function($element) {
    return $item->selected != true;
});

or pull method

$selected = []; 
foreach ($collection as $key => $item) {
      if ($item->selected == true) {
          $selected[] = $collection->pull($key);
      }
}

Starting with parameter:

This may depend on the software which created the setup.exe.

Yes. Look at http://jerrywickey.com/test/testJerrysLibrary.php

It gives sample code examples for RSA encryption and decryption in PHP as well as RSA encryption in javascript.

If you want to encrypt text instead of just base 10 numbers, you'll also need a base to base conversion. That is convert text to a very large number. Text is really just writing in base 63. 26 lowercase letters plus 26 uppercase + 10 numerals + space character. The code for that is below also.

The $GETn parameter is a file name that holds keys for the cryption functions. If you don't figure it out, ask. I'll help.

I actually posted this whole encryption library yesterday, but Brad Larson a mod, killed it and said this kind of stuff isn't really what Stack Overflow is about. But you can still find all the code examples and the whole function library to carry out client/server encryption decryption for AJAX at the link above.

A possible explanation is that the selectlist value that you are binding to is not a string.

So in that example, is the parameter 'PageOptionsDropDown' a string in your model? Because if it isn't then the selected value in the list wouldn't be shown.

The easiest way to do this is with 2 divs, 1 with the background and 1 with the text:

#container {_x000D_
  position: relative;_x000D_
  width: 300px;_x000D_
  height: 200px;_x000D_
}_x000D_
#block {_x000D_
  background: #CCC;_x000D_
  filter: alpha(opacity=60);_x000D_
  /* IE */_x000D_
  -moz-opacity: 0.6;_x000D_
  /* Mozilla */_x000D_
  opacity: 0.6;_x000D_
  /* CSS3 */_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
}_x000D_
#text {_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
}

<div id="container">_x000D_
  <div id="block"></div>_x000D_
  <div id="text">Test</div>_x000D_
</div>

That isn't the Node.js command prompt window. That is a language shell to run JavaScript commands, also known as a REPL.

In Windows, there should be a Node.js command prompt in your Start menu or start screen:

Which will open a command prompt window that looks like this:

From there you can switch directories using the cd command.

To suppress output, use redirection to NUL.

There are two kinds of output that console commands use:

• standard output, or stdout,

• standard error, or stderr.

Of the two, stdout is used more often, both by internal commands, like copy, and by console utilities, or external commands, like find and others, as well as by third-party console programs.

>NUL suppresses the standard output and works fine e.g. for suppressing the 1 file(s) copied. message of the copy command. An alternative syntax is 1>NUL. So,

COPY file1 file2 >NUL

or

COPY file1 file2 1>NUL

or

>NUL COPY file1 file2

or

1>NUL COPY file1 file2

suppresses all of COPY's standard output.

To suppress error messages, which are typically printed to stderr, use 2>NUL instead. So, to suppress a File Not Found message that DEL prints when, well, the specified file is not found, just add 2>NUL either at the beginning or at the end of the command line:

DEL file 2>NUL

or

2>NUL DEL file

Although sometimes it may be a better idea to actually verify whether the file exists before trying to delete it, like you are doing in your own solution. Note, however, that you don't need to delete the files one by one, using a loop. You can use a single command to delete the lot:

IF EXIST "%scriptDirectory%*.noext" DEL "%scriptDirectory%*.noext"

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

Sorry, not Swift, just a proof of concept in the closest language at hand.

// JavaScript POC. Output:
// Matches:  ["GOODBYE","CRUEL","WORLD","IM","LEAVING","U","TODAY"]

let str = `GOODBYE,CRUEL,WORLD,IM,LEAVING,U,TODAY`
let matches = [];

function recurse(str, matches) {
    let regex = /^((,?([A-Z]+))+)$/gm
    let m
    while ((m = regex.exec(str)) !== null) {
        matches.unshift(m[3])
        return str.replace(m[2], '')
    }
    return "bzzt!"
}

while ((str = recurse(str, matches)) != "bzzt!") ;
console.log("Matches: ", JSON.stringify(matches))

Note: If you were really going to use this, you would use the position of the match as given by the regex match function, not a string replace.

Change the Encoding of the stream writer. It's a property.

http://msdn.microsoft.com/en-us/library/system.io.streamwriter.encoding.aspx

So:

sw.Encoding = Encoding.GetEncoding(28591);

Prior to writing to the stream.

In here:

    if (ValidationUtils.isNullOrEmpty(lastName)) {
        registrationErrors.add(ValidationErrors.LAST_NAME);
    }
    if (!ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do

    if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.

I managed to use soap,wsdl and Node.js You need to install soap with npm install soap

Create a node server called server.js that will define soap service to be consumed by a remote client. This soap service computes Body Mass Index based on weight(kg) and height(m).

const soap = require('soap');
const express = require('express');
const app = express();
/**
 * this is remote service defined in this file, that can be accessed by clients, who will supply args
 * response is returned to the calling client
 * our service calculates bmi by dividing weight in kilograms by square of height in metres
 */
const service = {
  BMI_Service: {
    BMI_Port: {
      calculateBMI(args) {
        //console.log(Date().getFullYear())
        const year = new Date().getFullYear();
        const n = args.weight / (args.height * args.height);
        console.log(n);
        return { bmi: n };
      }
    }
  }
};
// xml data is extracted from wsdl file created
const xml = require('fs').readFileSync('./bmicalculator.wsdl', 'utf8');
//create an express server and pass it to a soap server
const server = app.listen(3030, function() {
  const host = '127.0.0.1';
  const port = server.address().port;
});
soap.listen(server, '/bmicalculator', service, xml);

Next, create a client.js file that will consume soap service defined by server.js. This file will provide arguments for the soap service and call the url with SOAP's service ports and endpoints.

const express = require('express');
const soap = require('soap');
const url = 'http://localhost:3030/bmicalculator?wsdl';
const args = { weight: 65.7, height: 1.63 };
soap.createClient(url, function(err, client) {
  if (err) console.error(err);
  else {
    client.calculateBMI(args, function(err, response) {
      if (err) console.error(err);
      else {
        console.log(response);
        res.send(response);
      }
    });
  }
});

Your wsdl file is an xml based protocol for data exchange that defines how to access a remote web service. Call your wsdl file bmicalculator.wsdl

<definitions name="HelloService" targetNamespace="http://www.examples.com/wsdl/HelloService.wsdl"

You can try this query in any given SQL Server database:

SELECT 
    name,
    create_date,
    modify_date
FROM sys.procedures
WHERE create_date = '20120927'  

which lists out the name, the creation and the last modification date - unfortunately, it doesn't record who created and/or modified the stored procedure in question.

Assuming (!) the strings are of equal length, why not convert the strings to byte arrays and then XOR the bytes. The resultant byte arrays may be of different lengths too depending on your encoding (e.g. UTF8 will expand to different byte lengths for different characters).

You should be careful to specify the character encoding to ensure consistent/reliable string/byte conversion.

New ways to align items right:

Grid:

.header {
        display:grid;
        grid-template-columns: 1fr auto;
    }

Demo

Bootstrap 4. Align right:

<div class="row">
      <div class="col">left</div>
      <div class="col">
          <div class="float-right">element needs to be right aligned</div>
      </div>
</div>

Demo

Xamarin.Forms supports multiple navigation hosts built-in:

• NavigationPage, where the next page slide in,
• TabbedPage, the one you don't like
• CarouselPage, that allows for switching left and right to next/prev pages.

On top of this, all pages also supports PushModalAsync() which just push a new page on top of the existing one.

At the very end, if you want to make sure the user can't get back to the previous page (using a gesture or the back hardware button), you can keep the same Page displayed and replace its Content.

The suggested options of replacing the root page works as well, but you'll have to handle that differently for each platform.

I feel like the simplest solution is sans javascript and simply putting the link in each cell (provided you don't have massive gullies between your cells or really think border lines). Have your css:

.tableClass td a{
   display: block;
}

and then add a link per cell:

<table class="tableClass">
    <tr>
        <td><a href="#link">Link name</a></td>
        <td><a href="#link">Link description</a></td>
        <td><a href="#link">Link somthing else</a></td>
    </tr>
</table>

boring but clean.

The problem with Java console input is that it's buffered input, and requires an enter key to continue.

There are these two discussions: Detecting and acting on keyboard direction keys in Java and Java keyboard input parsing in a console app

The latter of which used JLine to get his problem solved.

I personally haven't used it.

This is a variation on this answer, currently suggested by gitlab to "migrate" a git repository from one server to another.

1. Let us assume that your old project is called existing_repo, stored in a existing_repo folder.

2. Create a repo on your new server. We will assume that the url of that new project is git@newserver:newproject.git

3. Open a command-line interface, and enter the following:

   cd existing_repo
   git remote rename origin old-origin
   git remote add origin git@newserver:newproject.git
   git push -u origin --all
   git push -u origin --tags
   

The benefits of this approach is that you do not delete the branch that corresponds to your old server.

Following code might Help you.

I have taken UITableView with custom prototype cell class named UITableViewCell inside UIViewController.

So i have ViewController.h, ViewController.m and TableViewCell.h,TableViewCell.m

Here is the code for that:

ViewController.h

@interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>

@property (strong, nonatomic) IBOutlet UITableView *tblView;

@end

ViewController.m

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return (YourNumberOfRows);
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier = @"cell";

    __weak TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

    if (indexPath.row==0) {
        [cell setDidTapButtonBlock:^(id sender)
         {
             // Your code here

         }];
    }    
    return cell;
}

Custom cell class :

TableViewCell.h

@interface TableViewCell : UITableViewCell

@property (copy, nonatomic) void (^didTapButtonBlock)(id sender);

@property (strong, nonatomic) IBOutlet UILabel *lblTitle;
@property (strong, nonatomic) IBOutlet UIButton *btnAction;

- (void)setDidTapButtonBlock:(void (^)(id sender))didTapButtonBlock;

@end

and

UITableViewCell.m

@implementation TableViewCell

- (void)awakeFromNib {
    // Initialization code
    [self.btnAction addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];

}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}
- (void)didTapButton:(id)sender {
    if (self.didTapButtonBlock)
    {
        self.didTapButtonBlock(sender);
    }
}

Note: Here I have taken all UIControls using Storyboard.

Hope that can help you...!!!

For anyone reading this and using Postgres.app, you may need host: localhost in your database.yml. http://postgresapp.com/documentation#toc_3

EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value syntax is incorrect.

I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. error message. In 2008, the modified script is still successful.

declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)

Try building your project from the Powershell command line:

dotnet build

Then you can see any errors in the command line output even if Visual Studio is playing hide and seek with build error messages.

Try this:

var hms = '02:04:33';   // your input string
var a = hms.split(':'); // split it at the colons

// minutes are worth 60 seconds. Hours are worth 60 minutes.
var seconds = (+a[0]) * 60 * 60 + (+a[1]) * 60 + (+a[2]); 

console.log(seconds);

replace method of string objects does not accept regular expressions but only fixed strings (see documentation: http://docs.python.org/2/library/stdtypes.html#str.replace).

You have to use re module:

import re
newline= re.sub("<\/?\[[0-9]+>", "", line)

Not sure if this is helpful for you, but removing the container always helps.

So, if you use docker-compose for your setup, you can simply use docker-compose down && docker-compose up instead of docker-compose restart. With a proper setup (make sure to use volume mounts for persistent data), you don't lose any data this way.

Sure, this is more than the OP requested. But there are various situations where the other answers cannot help (if using a remote docker server or working on a Windows machine, accessing the underlying filesystem is proprietary and difficult)

In Vue2 be aware that you can access this.$refs.uniqueName only after mounting the component.

It's easier to use the timestamp for this things since Tweepy gets both

import datetime
print(datetime.datetime.fromtimestamp(int(t1)).strftime('%H:%M'))

If you don't use a compacting garbage collector, you can have some sort of a memory leak due to heap fragmentation.

I fixed this issue on machine disabling the loopback check setting:

1. Edit the Windows registry: Start –> Run > Regedit
2. Navigate to: HKLM\System\CurrentControlSet\Control\LSA
3. Add a DWORD value called “DisableLoopbackCheck”
4. Set this value to 1

I found this extension for VS code called Git Merger. It adds Git: Merge from to the commands.

• <% %> : Executes the ruby code
• <%= %> : Prints into Erb file. Or browser
• <% -%> : Avoids line break after expression.
• <%# %> : ERB comment

Depending on your needs, this can be one step or two steps

1. use encode() to convert string to bytes, immutable
2. use bytearray() to convert bytes to bytearray, mutable

s="ABCD"
encoded=s.encode('utf-8')
array=bytearray(encoded)

The following validation is done in Python 3.7

>>> s="ABCD"
>>> encoded=s.encode('utf-8')
>>> encoded
b'ABCD'
>>> array=bytearray(encoded)
>>> array
bytearray(b'ABCD')

hi guys after one day searching on web finally i solve problem with below source code hope to help you

    public UploadResult UploadFile(string  fileAddress)
    {
        HttpClient client = new HttpClient();

        MultipartFormDataContent form = new MultipartFormDataContent();
        HttpContent content = new StringContent("fileToUpload");
        form.Add(content, "fileToUpload");       
        var stream = new FileStream(fileAddress, FileMode.Open);            
        content = new StreamContent(stream);
        var fileName = 
        content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
        {
            Name = "name",
            FileName = Path.GetFileName(fileAddress),                 
        };
        form.Add(content);
        HttpResponseMessage response = null;          

        var url = new Uri("http://192.168.10.236:2000/api/Upload2");
        response = (client.PostAsync(url, form)).Result;          

    }

I don't understand what the meaning of ordering with the same column ASC and DESC in the same ORDER BY, but this how you can do it: naam DESC, naam ASC like so:

ORDER BY `product_category_id` DESC,`naam` DESC, `naam` ASC

var dt = DateTime.Now; 
var unixTime = ((DateTimeOffset)dt).ToUnixTimeSeconds();

// 1510396991

var dt = DateTimeOffset.FromUnixTimeSeconds(1510396991);

// [11.11.2017 10:43:11 +00:00]

Performance: No impact on performance as byte code is same. though it will lead to some compile overheads.

Compilation: on my personal machine, Compiling a blank class without importing anything takes 100 ms but same class when import java.* takes 170 ms.

To use uint8_t type alias, you have to include stdint.h standard header.

I had this problem i.e. works fine when pasted into browser but 505s when done through java. It was simply the spaces that needed to be escaped/encoded.

.sort(), in pymongo, takes key and direction as parameters.

So if you want to sort by, let's say, id then you should .sort("_id", 1)

For multiple fields:

.sort([("field1", pymongo.ASCENDING), ("field2", pymongo.DESCENDING)])

Found another solution:

• Apply the formula to the first 3 or 4 cells of the column
• Ctrl + C the formula in one of the last rows (if you copy the first line it won't work)
• Click on the column header to select the whole column
• Press Ctrl + V to paste it in all cells bellow

In Node.js, you can use its native require("assert").deepStrictEqual. More info: http://nodejs.org/api/assert.html

For example:

var assert = require("assert");
assert.deepStrictEqual({a:1, b:2}, {a:1, b:3}); // will throw AssertionError

Another example that returns true / false instead of returning errors:

var assert = require("assert");

function deepEqual(a, b) {
    try {
      assert.deepEqual(a, b);
    } catch (error) {
      if (error.name === "AssertionError") {
        return false;
      }
      throw error;
    }
    return true;
};

A timestamp is a point in time. Typically this can be represented by a number of milliseconds past an epoc (the Unix Epoc of Jan 1 1970 12AM UTC). The format of that point in time depends on the time zone. While it is the same point in time, the "hours value" is not the same among time zones and one must take into account the offset from the UTC.

Here's some code to illustrate. A point is time is captured in three different ways.

var moment = require( 'moment' );

var localDate = new Date();
var localMoment = moment();
var utcMoment = moment.utc();
var utcDate = new Date( utcMoment.format() );

//These are all the same
console.log( 'localData unix = ' + localDate.valueOf() );
console.log( 'localMoment unix = ' + localMoment.valueOf() );
console.log( 'utcMoment unix = ' + utcMoment.valueOf() );

//These formats are different
console.log( 'localDate = ' + localDate );
console.log( 'localMoment string = ' + localMoment.format() );
console.log( 'utcMoment string = ' + utcMoment.format() );
console.log( 'utcDate  = ' + utcDate );

//One to show conversion
console.log( 'localDate as UTC format = ' + moment.utc( localDate ).format() );
console.log( 'localDate as UTC unix = ' + moment.utc( localDate ).valueOf() );

Which outputs this:

localData unix = 1415806206570
localMoment unix = 1415806206570
utcMoment unix = 1415806206570
localDate = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localMoment string = 2014-11-12T10:30:06-05:00
utcMoment string = 2014-11-12T15:30:06+00:00
utcDate  = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localDate as UTC format = 2014-11-12T15:30:06+00:00
localDate as UTC unix = 1415806206570

In terms of milliseconds, each are the same. It is the exact same point in time (though in some runs, the later millisecond is one higher).

As far as format, each can be represented in a particular timezone. And the formatting of that timezone'd string looks different, for the exact same point in time!

Are you going to compare these time values? Just convert to milliseconds. One value of milliseconds is always less than, equal to or greater than another millisecond value.

Do you want to compare specific 'hour' or 'day' values and worried they "came from" different timezones? Convert to UTC first using moment.utc( existingDate ), and then do operations. Examples of those conversions, when coming out of the DB, are the last console.log calls in the example.

        InitializeComponent();

        string myHost = System.Net.Dns.GetHostName();
        string myIP = null;

        for (int i = 0; i <= System.Net.Dns.GetHostEntry(myHost).AddressList.Length - 1; i++)
        {
            if (System.Net.Dns.GetHostEntry(myHost).AddressList[i].IsIPv6LinkLocal == false)
            {
                myIP = System.Net.Dns.GetHostEntry(myHost).AddressList[i].ToString();
            }
        }
    }

Declare myIP and myHost in public Variable and use in any function of the form.

You can use this :

@GET("group/{id}/users")

Call<List<User>> groupList(@Path("id") int groupId, @Query("sort") String sort);

Try to install nodemon globally.

sudo npm install -g nodemon

IN windows open cmd

go to directory where your netbeans downloaded

then run below command JDK path may be different from the path I mentioned

netbeans-8.2-windows.exe --javahome "C:\Program Files\Java\jdk-9.0.1"

if you face issue in existing installed in netbeans you can find details in here

... you can use it on any granularity type i.e.:

DATEPART(YEAR, [date])

DATEPART(MONTH, [date]) 

DATEPART(DAY, [date])    

DATEPART(HOUR, [date]) 

DATEPART(MINUTE, [date])

(note: I like the [ ] around the date reserved word though. Of course that's in case your column with timestamp is labeled "date")

If you want to display links coming from your state or store in Vue 2.0, you can do like this:

<a v-bind:href="''"> {{ url_link }} </a>

Most likely, the remote host ip or ip_alias is not in the ~/.ssh/known_hosts file. You can use the following command to add the host name to known_hosts file.

$ssh-keyscan -H -t rsa ip_or_ipalias >> ~/.ssh/known_hosts

Also, I have generated the following script to check if the particular ip or ipalias is in the know_hosts file.

#!/bin/bash
#Jason Xiong: Dec 2013   
# The ip or ipalias stored in known_hosts file is hashed and   
# is not human readable.This script check if the supplied ip    
# or ipalias exists in ~/.ssh/known_hosts file

if [[ $# != 2 ]]; then
   echo "Usage: ./search_known_hosts -i ip_or_ipalias"
   exit;
fi
ip_or_alias=$2;
known_host_file=/home/user/.ssh/known_hosts
entry=1;

cat $known_host_file | while read -r line;do
  if [[ -z "$line" ]]; then
    continue;
  fi   
  hash_type=$(echo $line | sed -e 's/|/ /g'| awk '{print $1}'); 
  key=$(echo $line | sed -e 's/|/ /g'| awk '{print $2}');
  stored_value=$(echo $line | sed -e 's/|/ /g'| awk '{print $3}'); 
  hex_key=$(echo $key | base64 -d | xxd -p); 
  if  [[ $hash_type = 1 ]]; then      
     gen_value=$(echo -n $ip_or_alias | openssl sha1 -mac HMAC \
         -macopt hexkey:$hex_key | cut -c 10-49 | xxd -r -p | base64);     
     if [[ $gen_value = $stored_value ]]; then
       echo $gen_value;
       echo "Found match in known_hosts file : entry#"$entry" !!!!"
     fi
  else
     echo "unknown hash_type"
  fi
  entry=$((entry + 1));
done

You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?

if (query.list().size() == 1) 

Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.

This is a nice 5-part tutorial that covers a lot of useful material: http://mobile.tutsplus.com/tutorials/phonegap/phonegap-from-scratch/
(Anyone else noticing a trend forming here??? hehehee )

Edit I just finished a nice four part tutorial building an app to write, save, edit, & delete notes using jQuery mobile (only), it was very practical & useful, but it was also only for jQM. So, I looked to see what else they had on DZone.

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

WHERE NULLIF(your_column, '') IS NOT NULL

Nowadays (4.5 years on), to make it easier for a human to read, I would just use

WHERE your_column <> ''

While there is a temptation to make the null check explicit...

WHERE your_column <> '' 
      AND your_column IS NOT NULL

...as @Martin Smith demonstrates in the accepted answer, it doesn't really add anything (and I personally shun SQL nulls entirely nowadays, so it wouldn't apply to me anyway!).

Since the rules are running in JavaScript, why not disable them using javascript (or in my examples case, jQuery)?

$('#fieldId').attr('disabled', 'disabled'); //Disable
$('#fieldId').removeAttr('disabled'); //Enable

UPDATE

The attr function is no longer the primary approach to this, as was pointed out in the comments below. This is now done with the prop function.

$( "input" ).prop( "disabled", true ); //Disable
$( "input" ).prop( "disabled", false ); //Enable

It's easier using Array.filter:

var unique = arr.filter(function(elem, index, self) {
    return index === self.indexOf(elem);
})

As short as @jumbo's answer is :-) you can do it even more tersely. This just returns the Count property of the array returned by the antecedent sub-expression:

@(Get-Alias).Count

A couple points to note:

1. You can put an arbitrarily complex expression in place of Get-Alias, for example:

   @(Get-Process | ? { $_.ProcessName -eq "svchost" }).Count
   

2. The initial at-sign (@) is necessary for a robust solution. As long as the answer is two or greater you will get an equivalent answer with or without the @, but when the answer is zero or one you will get no output unless you have the @ sign! (It forces the Count property to exist by forcing the output to be an array.)

2012.01.30 Update

The above is true for PowerShell V2. One of the new features of PowerShell V3 is that you do have a Count property even for singletons, so the at-sign becomes unimportant for this scenario.

You get and format like this

for /f "tokens=1-4 delims=/ " %%i in ("%date%") do (
     set dow=%%i
     set month=%%j
     set day=%%k
     set year=%%l
)
set datestr=%month%_%day%_%year%
echo datestr is %datestr%

Note: Above only works on US locale. It assumes the output of echo %date% looks like this: Thu 02/13/21. If you have different Windows locale settings, you will need to modify the script based on your configuration.

Here's how you accomplish that:

//View.cshtml
<script type="text/javascript">
    var arrayOfArrays = JSON.parse('@Html.Raw(Json.Encode(Model.Addresses))');
</script>

In my case, it was caused from gms services 4.3.0. So i had to change it to:

com.google.gms:google-services:4.2.0

I have found this by running:

gradlew sync -Pandroid.debug.obsoleteApi=true

in terminal. Go to view -> tool windows -> Terminal in Android Studio.

I am working MacOS 10.10. I have updated gcc to version 4.9 to make it work.

brew update
brew install gcc
brew reinstall r

One thing I find easy to do is i set an array of empty strings for the size I prefer, for example

Code:

import numpy as np

x= np.zeros(5,str)
print x

Output:

['' '' '' '' '']

Hope this is helpful :)

I had a sub folder named web.config renaming this folder resolved the issue

You have to add a manifest permission entry:

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

(of course you should list all other permissions that your app uses).

Then, implement BroadcastReceiver class, it should be simple and fast executable. The best approach is to set an alarm in this receiver to wake up your service (if it's not necessary to keep it running ale the time as Prahast wrote).

public class BootUpReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, MyService.class), PendingIntent.FLAG_UPDATE_CURRENT);
        am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, interval, pi);
    }
}

Then, add a Receiver class to your manifest file:

<receiver android:enabled="true" android:name=".receivers.BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

In the past months, I used a "preview" version of Android Studio. I tried to switch back to the "stable" releases for the software updates but it wasn't enough and I got this famous error you talk of.

Uninstalling my Android Studio 2.2.preview and installing latest stable Android Studio (2.1) fixed it for me :)

You can also use linq extensions for DataSets:

var imagePaths = dt.AsEnumerble().Select(r => r.Field<string>("ImagePath");
foreach(string imgPath in imagePaths)
{
    TextBox1.Text = imgPath;
}

You can use a library I wrote, FormPersistence.js which handles form (de)serialization by saving values to local/session storage. This approach is similar to that linked in another answer but it does not require jQuery and does not save plaintext passwords to web storage.

let myForm = document.getElementById('my-form')
FormPersistence.persist(myForm, true)

The optional second parameter of each FormPersistence function defines whether to use local storage (false) or session storage (true). In your case, session storage is likely more appropriate.

The form data by default will be cleared from storage upon submission, unless you pass false as the third parameter. If you have special value handling functions (such as inserting an element) then you can pass those as the fourth parameter. See the repository for complete documentation.

If you are in windows you can just run

net user postgres postgres

and login in postgres with postgres/postgres as user/password

Simply the answer according to my reading and understanding to this thread and @remus-rusanu answer is based on this simple scenario:

There are two transactions A and B. Transaction B is reading Table X Transaction A is writing in table X Transaction B is reading again in Table X.

• ReadUncommitted: Transaction B can read uncommitted data from Transaction A and it could see different rows based on B writing. No lock at all
• ReadCommitted: Transaction B can read ONLY committed data from Transaction A and it could see different rows based on COMMITTED only B writing. could we call it Simple Lock?
• RepeatableRead: Transaction B will read the same data (rows) whatever Transaction A is doing. But Transaction A can change other rows. Rows level Block
• Serialisable: Transaction B will read the same rows as before and Transaction A cannot read or write in the table. Table-level Block
• Snapshot: every Transaction has its own copy and they are working on it. Each one has its own view

you can use this too

echo substr($_SERVER['HTTP_HOST'], 0, strrpos($_SERVER['HTTP_HOST'], '.', -5));

You could try to create your own color palette using the RColorBrewer package

my_palette <- colorRampPalette(c("green", "black", "red"))(n = 1000)

and see how this looks like. But I assume in your case only scaling would help if you really want to keep the black in "the middle". You can simply use my_palette instead of the redgreen()

I recommend that you check out the RColorBrewer package, they have pretty nice in-built palettes, and see interactive website for colorbrewer.

if you are using Eclipse watch your POM dependencies and your Eclipse buildpath dependency on junit

if you select use Junit4 eclipse create TestCase using org.junit package but your POM use by default Junit3 (junit.framework package) that is the cause, like this picture:

Just update your Junit dependency in your POM file to Junit4 or your Eclipse BuildPath to Junit3

GWT in Intellij 12

FWIW, I was getting a similar error with my GWT application during 'Build | Rebuild Project'.

This was caused by Intellij doing a full GWT compile which I didn't like because it is also a very lengthy process.

I disabled GWT compile by turning off the module check boxes under 'Project Structure | Facets | GWT'.

Alternatively there is a 'Compiler maximum heap size' setting in that location as well.

I'll give 4 solutions:

1) Using Fernet encryption with cryptography library

Here is a solution using the package cryptography, that you can install as usual with pip install cryptography:

import base64
from cryptography.fernet import Fernet, InvalidToken
from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC

def cipherFernet(password):
    key = PBKDF2HMAC(algorithm=hashes.SHA256(), length=32, salt=b'abcd', iterations=1000, backend=default_backend()).derive(password)
    return Fernet(base64.urlsafe_b64encode(key))

def encrypt1(plaintext, password):
    return cipherFernet(password).encrypt(plaintext)

def decrypt1(ciphertext, password):
    return cipherFernet(password).decrypt(ciphertext)

# Example:

print(encrypt1(b'John Doe', b'mypass'))  
# b'gAAAAABd53tHaISVxFO3MyUexUFBmE50DUV5AnIvc3LIgk5Qem1b3g_Y_hlI43DxH6CiK4YjYHCMNZ0V0ExdF10JvoDw8ejGjg=='
print(decrypt1(b'gAAAAABd53tHaISVxFO3MyUexUFBmE50DUV5AnIvc3LIgk5Qem1b3g_Y_hlI43DxH6CiK4YjYHCMNZ0V0ExdF10JvoDw8ejGjg==', b'mypass')) 
# b'John Doe'
try:  # test with a wrong password
    print(decrypt1(b'gAAAAABd53tHaISVxFO3MyUexUFBmE50DUV5AnIvc3LIgk5Qem1b3g_Y_hlI43DxH6CiK4YjYHCMNZ0V0ExdF10JvoDw8ejGjg==', b'wrongpass')) 
except InvalidToken:
    print('Wrong password')

You can adapt with your own salt, iteration count, etc. This code is not very far from @HCLivess's answer but the goal is here to have ready-to-use encrypt and decrypt functions. Source: https://cryptography.io/en/latest/fernet/#using-passwords-with-fernet.

Note: use .encode() and .decode() everywhere if you want strings 'John Doe' instead of bytes like b'John Doe'.

2) Simple AES encryption with Crypto library

This works with Python 3:

import base64
from Crypto import Random
from Crypto.Hash import SHA256
from Crypto.Cipher import AES

def cipherAES(password, iv):
    key = SHA256.new(password).digest()
    return AES.new(key, AES.MODE_CFB, iv)

def encrypt2(plaintext, password):
    iv = Random.new().read(AES.block_size)
    return base64.b64encode(iv + cipherAES(password, iv).encrypt(plaintext))

def decrypt2(ciphertext, password):
    d = base64.b64decode(ciphertext)
    iv, ciphertext = d[:AES.block_size], d[AES.block_size:]
    return cipherAES(password, iv).decrypt(ciphertext)

# Example:    

print(encrypt2(b'John Doe', b'mypass'))
print(decrypt2(b'B/2dGPZTD8V22cIVKfp2gD2tTJG/UfP/', b'mypass'))
print(decrypt2(b'B/2dGPZTD8V22cIVKfp2gD2tTJG/UfP/', b'wrongpass'))  # wrong password: no error, but garbled output

Note: you can remove base64.b64encode and .b64decode if you don't want text-readable output and/or if you want to save the ciphertext to disk as a binary file anyway.

3) AES using a better password key derivation function and the ability to test if "wrong password entered", with Crypto library

The solution 2) with AES "CFB mode" is ok, but has two drawbacks: the fact that SHA256(password) can be easily bruteforced with a lookup table, and that there is no way to test if a wrong password has been entered. This is solved here by the use of AES in "GCM mode", as discussed in AES: how to detect that a bad password has been entered? and Is this method to say “The password you entered is wrong” secure?:

import Crypto.Random, Crypto.Protocol.KDF, Crypto.Cipher.AES

def cipherAES_GCM(pwd, nonce):
    key = Crypto.Protocol.KDF.PBKDF2(pwd, nonce, count=100000)
    return Crypto.Cipher.AES.new(key, Crypto.Cipher.AES.MODE_GCM, nonce=nonce, mac_len=16)

def encrypt3(plaintext, password):
    nonce = Crypto.Random.new().read(16)
    return nonce + b''.join(cipherAES_GCM(password, nonce).encrypt_and_digest(plaintext))  # you case base64.b64encode it if needed

def decrypt3(ciphertext, password):
    nonce, ciphertext, tag = ciphertext[:16], ciphertext[16:len(ciphertext)-16], ciphertext[-16:]
    return cipherAES_GCM(password, nonce).decrypt_and_verify(ciphertext, tag)

# Example:

print(encrypt3(b'John Doe', b'mypass'))
print(decrypt3(b'\xbaN_\x90R\xdf\xa9\xc7\xd6\x16/\xbb!\xf5Q\xa9]\xe5\xa5\xaf\x81\xc3\n2e/("I\xb4\xab5\xa6ezu\x8c%\xa50', b'mypass'))
try:
    print(decrypt3(b'\xbaN_\x90R\xdf\xa9\xc7\xd6\x16/\xbb!\xf5Q\xa9]\xe5\xa5\xaf\x81\xc3\n2e/("I\xb4\xab5\xa6ezu\x8c%\xa50', b'wrongpass'))
except ValueError:
    print("Wrong password")

4) Using RC4 (no library needed)

Adapted from https://github.com/bozhu/RC4-Python/blob/master/rc4.py.

def PRGA(S):
    i = 0
    j = 0
    while True:
        i = (i + 1) % 256
        j = (j + S[i]) % 256
        S[i], S[j] = S[j], S[i]
        yield S[(S[i] + S[j]) % 256]

def encryptRC4(plaintext, key, hexformat=False):
    key, plaintext = bytearray(key), bytearray(plaintext)  # necessary for py2, not for py3
    S = list(range(256))
    j = 0
    for i in range(256):
        j = (j + S[i] + key[i % len(key)]) % 256
        S[i], S[j] = S[j], S[i]
    keystream = PRGA(S)
    return b''.join(b"%02X" % (c ^ next(keystream)) for c in plaintext) if hexformat else bytearray(c ^ next(keystream) for c in plaintext)

print(encryptRC4(b'John Doe', b'mypass'))                           # b'\x88\xaf\xc1\x04\x8b\x98\x18\x9a'
print(encryptRC4(b'\x88\xaf\xc1\x04\x8b\x98\x18\x9a', b'mypass'))   # b'John Doe'

(Outdated since the latest edits, but kept for future reference): I had problems using Windows + Python 3.6 + all the answers involving pycrypto (not able to pip install pycrypto on Windows) or pycryptodome (the answers here with from Crypto.Cipher import XOR failed because XOR is not supported by this pycrypto fork ; and the solutions using ... AES failed too with TypeError: Object type <class 'str'> cannot be passed to C code). Also, the library simple-crypt has pycrypto as dependency, so it's not an option.

I have the same problem and found that this is the problem of Microsoft vulnerabilities.

It works for me when I install these update patches. You can find these patches on www.microsoft.com .

1. If your office 2010 version is SP1, you need download and install office SP2 pack first. Update patch name is KB2687455.

2. Install update patch KB2965240.

   This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if an attacker convinces a user to open or preview a specially crafted Microsoft Excel workbook in an affected version of Office. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user.

3. Install update patch KB2553154.

   A security vulnerability exists in Microsoft Office 2010 32-Bit Edition that could allow arbitrary code to run when a maliciously modified file is opened. This update resolves that vulnerability.

You can try more reusable my solution with callback function. In this function you can use POST request or some logic. Used libraries: JQuery 3> and Bootstrap 3>.

https://jsfiddle.net/axnikitenko/gazbyv8v/

Html code for test:

...
<body>
    <a href='#' id="remove-btn-a-id" class="btn btn-default">Test Remove Action</a>
</body>
...

Javascript:

$(function () {
    function remove() {
        alert('Remove Action Start!');
    }
    // Example of initializing component data
    this.cmpModalRemove = new ModalConfirmationComponent('remove-data', remove,
        'remove-btn-a-id', {
            txtModalHeader: 'Header Text For Remove', txtModalBody: 'Body For Text Remove',
            txtBtnConfirm: 'Confirm', txtBtnCancel: 'Cancel'
        });
    this.cmpModalRemove.initialize();
});

This is fixed in Hamcrest 1.3. The below code compiles and does not generate any warnings:

// given
List<String> list = new ArrayList<String>();
// then
assertThat(list, is(not(empty())));

But if you have to use older version - instead of bugged empty() you could use:

hasSize(greaterThan(0))
(import static org.hamcrest.number.OrderingComparison.greaterThan; or
import static org.hamcrest.Matchers.greaterThan;)

Example:

// given
List<String> list = new ArrayList<String>();
// then
assertThat(list, hasSize(greaterThan(0)));

The most important thing about above solutions is that it does not generate any warnings. The second solution is even more useful if you would like to estimate minimum result size.

If your request is sent by HTTPS you will have an extra server variable named 'HTTPS'

if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') { //HTTPS } 

You may also need the following directive to be set before the first "sub_filter" for backend-servers with data compression:

proxy_set_header Accept-Encoding "";

Otherwise it may not work. For your example it will look like:

location /admin/ {
    proxy_pass http://localhost:8080/;
    proxy_set_header Accept-Encoding "";
    sub_filter "http://your_server/" "http://your_server/admin/";
    sub_filter_once off;
}

Use this Code: this method works on 4.3+ and also for below versions too.

   try {

         Process process = null;

        if(Build.VERSION.SDK_INT <= 16) {
            // shiny APIS 
               process = Runtime.getRuntime().exec(
                    "/system/bin/ping -w 1 -c 1 " + url);


        } 
        else 
        {

                   process = new ProcessBuilder()
                 .command("/system/bin/ping", url)
                 .redirectErrorStream(true)
                 .start();

            }



        BufferedReader reader = new BufferedReader(new InputStreamReader(
                process.getInputStream()));

        StringBuffer output = new StringBuffer();
        String temp;

        while ( (temp = reader.readLine()) != null)//.read(buffer)) > 0)
        {
            output.append(temp);
            count++;
        }

        reader.close();


        if(count > 0)
            str = output.toString();

        process.destroy();
     } catch (IOException e) {
         e.printStackTrace();
    }

    Log.i("PING Count", ""+count);
    Log.i("PING String", str);

Going off of what Surreal Dreams said, it's probably best to style the anchor tag in my experience, but it really does depend on what you are doing. Here's an example:

Html:

<div class="parent-div">
  <a href="#">Test</a>
  <a href="#">Test</a>
  <a href="#">Test</a>
</div>

Then the CSS:

.parent-div {
  width: 200px;
}
a {
  display:block;
  background-color: #ccc;
  color: #000;
  text-decoration:none;
  padding:10px;
  margin-bottom:1px;
}
a:hover {
  background-color: #ddd;
}

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

Same issue is also occuring for jcenter.

From 13 Jan 2020 onwards, Jcenter is only available at HTTPS.

Projects getting their dependencies using the same will start facing issues. For quick fixes do the following in your build.gradle

instead of

repositories {
jcenter ()
//others
}

use this:

repositories {
jcenter { url "http://jcenter.bintray.com/"}
//others
}

All modal/lightbox javascript-based systems use an overflow when displaying the modal/lightbox, on html tag or body tag.

When lightbox is show, the js push a overflow hidden on html or body tag. When lightbox is hidden, some remove the hidden other push a overflow auto on html or body tag.

Developers who work on Mac, do not see the problem of the scrollbar.

Just replace the hidden by an unset not to see the content slipping under the modal of the removal of the scrollbar.

Lightbox open/show:

<html style="overflow: unset;"></html>

Lightbox close/hide:

<html style="overflow: auto;"></html>

If you've done something like accidentally npm link generator-webapp after you've changed it, you can fix it by cloning the right generator and linking that.

git clone https://github.com/yeoman/generator-webapp.git;
# for fixing generator-webapp, replace with your required repository
cd generator-webapp;
npm link;

You can use System.out.printf() like this if you want to get nicely formatted

System.out.printf("%-20s %s\n", Name, Income);

Prints like:

Jaden             100000.0
Angela            70000.0
Bob               10000.0

This format means:

%-20s  -> this is the first argument, Name, left justified and padded to 20 spaces.
%s     -> this is the second argument, Income, if income is a decimal swap with %f
\n     -> new line character

You could also add formatting to the Income argument so that the number is printed as desired

Check out this for a quick reference

I think the easiest is using csvkit:

Gets the 2nd column: csvcut -c 2 file.csv

However, there's also csvtool, and probably a number of other csv bash tools out there:

sudo apt-get install csvtool (for Debian-based systems)

This would return a column with the first row having 'ID' in it. csvtool namedcol ID csv_file.csv

This would return the fourth row: csvtool col 4 csv_file.csv

If you want to drop the header row:

csvtool col 4 csv_file.csv | sed '1d'

SVG scaling and PNG rendering

Using pycairo and librsvg I was able to achieve SVG scaling and rendering to a bitmap. Assuming your SVG is not exactly 256x256 pixels, the desired output, you can read in the SVG to a Cairo context using rsvg and then scale it and write to a PNG.

main.py

import cairo
import rsvg

width = 256
height = 256

svg = rsvg.Handle('cool.svg')
unscaled_width = svg.props.width
unscaled_height = svg.props.height

svg_surface = cairo.SVGSurface(None, width, height)
svg_context = cairo.Context(svg_surface)
svg_context.save()
svg_context.scale(width/unscaled_width, height/unscaled_height)
svg.render_cairo(svg_context)
svg_context.restore()

svg_surface.write_to_png('cool.png')

RSVG C binding

From the Cario website with some minor modification. Also a good example of how to call a C-library from Python

from ctypes import CDLL, POINTER, Structure, byref, util
from ctypes import c_bool, c_byte, c_void_p, c_int, c_double, c_uint32, c_char_p


class _PycairoContext(Structure):
    _fields_ = [("PyObject_HEAD", c_byte * object.__basicsize__),
                ("ctx", c_void_p),
                ("base", c_void_p)]


class _RsvgProps(Structure):
    _fields_ = [("width", c_int), ("height", c_int),
                ("em", c_double), ("ex", c_double)]


class _GError(Structure):
    _fields_ = [("domain", c_uint32), ("code", c_int), ("message", c_char_p)]


def _load_rsvg(rsvg_lib_path=None, gobject_lib_path=None):
    if rsvg_lib_path is None:
        rsvg_lib_path = util.find_library('rsvg-2')
    if gobject_lib_path is None:
        gobject_lib_path = util.find_library('gobject-2.0')
    l = CDLL(rsvg_lib_path)
    g = CDLL(gobject_lib_path)
    g.g_type_init()

    l.rsvg_handle_new_from_file.argtypes = [c_char_p, POINTER(POINTER(_GError))]
    l.rsvg_handle_new_from_file.restype = c_void_p
    l.rsvg_handle_render_cairo.argtypes = [c_void_p, c_void_p]
    l.rsvg_handle_render_cairo.restype = c_bool
    l.rsvg_handle_get_dimensions.argtypes = [c_void_p, POINTER(_RsvgProps)]

    return l


_librsvg = _load_rsvg()


class Handle(object):
    def __init__(self, path):
        lib = _librsvg
        err = POINTER(_GError)()
        self.handle = lib.rsvg_handle_new_from_file(path.encode(), byref(err))
        if self.handle is None:
            gerr = err.contents
            raise Exception(gerr.message)
        self.props = _RsvgProps()
        lib.rsvg_handle_get_dimensions(self.handle, byref(self.props))

    def get_dimension_data(self):
        svgDim = self.RsvgDimensionData()
        _librsvg.rsvg_handle_get_dimensions(self.handle, byref(svgDim))
        return (svgDim.width, svgDim.height)

    def render_cairo(self, ctx):
        """Returns True is drawing succeeded."""
        z = _PycairoContext.from_address(id(ctx))
        return _librsvg.rsvg_handle_render_cairo(self.handle, z.ctx)

You must define Full-Text-Index on all tables in database where you require to use a query with CONTAINS which will take sometime.

Instead you can use the LIKE which will give you instant results without the need to adjust any settings for the tables.

Example:

SELECT * FROM ChartOfAccounts WHERE AccountName LIKE '%Tax%'

The same result obtained with CONTAINS can be obtained with LIKE.

see the result:

With my first view being MenuViewController I added:

MenuViewController *menuViewController = [[MenuViewController alloc]init];
self.window.rootViewController = menuViewController;

on the App Delegate method:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
}

That worked.

The solution using flexbox without justify-content: space-between.

<div class="title">
  <span>Cumulative performance</span>
  <span>20/02/2011</span>
</div>

.title {
  display: flex;
}

span:first-of-type {
  flex: 1;
}

When we use flex:1 on the first <span>, it takes up the entire remaining space and moves the second <span> to the right. The Fiddle with this solution: https://jsfiddle.net/2k1vryn7/

Here https://jsfiddle.net/7wvx2uLp/3/ you can see the difference between two flexbox approaches: flexbox with justify-content: space-between and flexbox with flex:1 on the first <span>.
