Programs & Examples On #Onbeforeprint

Here is a version that uses dataType html, but this is far less explicit, because i am returning an empty string to indicate an error.

Ajax call:

$.ajax({
  type : 'POST',
  url : 'post.php',
  dataType : 'html',
  data: {
      email : $('#email').val()
  },
  success : function(data){
      $('#waiting').hide(500);
      $('#message').removeClass().addClass((data == '') ? 'error' : 'success')
     .html(data).show(500);
      if (data == '') {
          $('#message').html("Format your email correcly");
          $('#demoForm').show(500);
      }
  },
  error : function(XMLHttpRequest, textStatus, errorThrown) {
      $('#waiting').hide(500);
      $('#message').removeClass().addClass('error')
      .text('There was an error.').show(500);
      $('#demoForm').show(500);
  }

});

post.php

<?php
sleep(1);

function processEmail($email) {
    if (preg_match("#^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$#", $email)) {
        // your logic here (ex: add into database)
        return true;
    }
    return false;
}

if (processEmail($_POST['email'])) {
    echo "<span>Your email is <strong>{$_POST['email']}</strong></span>";
}

There does not seem to be a straight-forward way provided by Google or Yahoo finance portals to download the full list of tickers. One possible 'brute force' way to get it is to query their APIs for every possible combinations of letters and save only those that return valid results. As silly as it may seem there are people who actually do it (ie. check this: http://investexcel.net/all-yahoo-finance-stock-tickers/).

You can download lists of symbols from exchanges directly or 3rd party websites as suggested by @Eugene S and @Capn Sparrow, however if you intend to use it to fetch data from Google or Yahoo, you have to sometimes use prefixes or suffixes to make sure that you're getting the correct data. This is because some symbols may repeat between exchanges, so Google and Yahoo prepend or append exchange codes to the tickers in order to distinguish between them. Here's an example:

Company:  Vodafone
------------------
LSE symbol:    VOD
 in Google:    LON:VOD
 in Yahoo:     VOD.L
NASDAQ symbol: VOD
 in Google:    NASDAQ:VOD
 in Yahoo:     VOD

Try this:

Xvfb :21 -screen 0 1024x768x24 +extension RANDR &

Xvfb --help

+extension name        Enable extension
-extension name        Disable extension

It depends mostly on how much the repository is used. With one user checking in once a day and a branch/merge/etc operation once a week you probably don't need to run it more than once a year.

With several dozen developers working on several dozen projects each checking in 2-3 times a day, you might want to run it nightly.

It won't hurt to run it more frequently than needed, though.

What I'd do is run it now, then a week from now take a measurement of disk utilization, run it again, and measure disk utilization again. If it drops 5% in size, then run it once a week. If it drops more, then run it more frequently. If it drops less, then run it less frequently.

As @DSM points out, you can do this more directly using the vectorised string methods:

df['Date'].str[-4:].astype(int)

Or using extract (assuming there is only one set of digits of length 4 somewhere in each string):

df['Date'].str.extract('(?P<year>\d{4})').astype(int)

An alternative slightly more flexible way, might be to use apply (or equivalently map) to do this:

df['Date'] = df['Date'].apply(lambda x: int(str(x)[-4:]))
             #  converts the last 4 characters of the string to an integer

The lambda function, is taking the input from the Date and converting it to a year.
You could (and perhaps should) write this more verbosely as:

def convert_to_year(date_in_some_format):
    date_as_string = str(date_in_some_format)  # cast to string
    year_as_string = date_in_some_format[-4:] # last four characters
    return int(year_as_string)

df['Date'] = df['Date'].apply(convert_to_year)

Perhaps 'Year' is a better name for this column...

I had also the ADT Bundle that had the HTTP as update url. Changing it to HTTPS solved the problem for me.

Neither UIImageView not UIImage holds on to the filename of the image loaded.

You can either

1: (as suggested by Kenny Winker above) subclass UIImageView to have a fileName property or

2: name the image files with numbers (image1.jpg, image2.jpg etc) and tag those images with the corresponding number (tag=1 for image1.jpg, tag=2 for image2.jpg etc) or

3: Have a class level variable (eg. NSString *currentFileName) which updates whenever you update the UIImageView's image

Below is the right code. Include JS files in following manner:

$(document).ready(function() {_x000D_
  $(function() {_x000D_
    $('#datetimepicker6').datetimepicker();_x000D_
    $('#datetimepicker7').datetimepicker({_x000D_
      useCurrent: false //Important! See issue #1075_x000D_
    });_x000D_
    $("#datetimepicker6").on("dp.change", function(e) {_x000D_
      $('#datetimepicker7').data("DateTimePicker").minDate(e.date);_x000D_
    });_x000D_
    $("#datetimepicker7").on("dp.change", function(e) {_x000D_
      $('#datetimepicker6').data("DateTimePicker").maxDate(e.date);_x000D_
    });_x000D_
  });_x000D_

you should try using os.walk

yourpath = 'path'

import os
for root, dirs, files in os.walk(yourpath, topdown=False):
    for name in files:
        print(os.path.join(root, name))
        stuff
    for name in dirs:
        print(os.path.join(root, name))
        stuff

Try request.setAttribute("param",value);. It worked fine for me.

Please find this code sample:

private void sanitizePrice(ServletRequest request){
        if(request.getParameterValues ("price") !=  null){
            String price[] = request.getParameterValues ("price");

            for(int i=0;i<price.length;i++){
                price[i] = price[i].replaceAll("[^\\dA-Za-z0-9- ]", "").trim();
                System.out.println(price[i]);
            }
            request.setAttribute("price", price);
            //request.getParameter("numOfBooks").re
        }
    }

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

Using #pragma once should work on any modern compiler, but I don't see any reason not to use a standard #ifndef include guard. It works just fine. The one caveat is that GCC didn't support #pragma once before version 3.4.

I also found that, at least on GCC, it recognizes the standard #ifndef include guard and optimizes it, so it shouldn't be much slower than #pragma once.

The error says "The index is out of range". That means you were trying to index an object with a value that was not valid. If you have two books, and I ask you to give me your third book, you will look at me funny. This is the computer looking at you funny. You said - "create a collection". So it did. But initially the collection is empty: not only is there nothing in it - it has no space to hold anything. "It has no hands".

Then you said "the first element of the collection is now 'ItemID'". And the computer says "I never was asked to create space for a 'first item'." I have no hands to hold this item you are giving me.

In terms of your code, you created a view, but never specified the size. You need a

dataGridView1.ColumnCount = 5;

Before trying to access any columns. Modify

DataGridView dataGridView1 = new DataGridView();

dataGridView1.Columns[0].Name = "ItemID";

to

DataGridView dataGridView1 = new DataGridView();
dataGridView1.ColumnCount = 5;
dataGridView1.Columns[0].Name = "ItemID";

See http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columncount.aspx

As explained, this is because your postgresql is in old version -> update it For Mac via homebrew:

brew tap petere/postgresql,

brew install <formula> (eg: brew install petere/postgresql/postgresql-9.6)

Remove old postgre:

brew unlink postgresql

brew link -f postgresql-9.6

If any error happen, don't forget to read and follow brew instruction in each step.

ILSpy works great!

As far as I can tell it does everything that Reflector did and looks the same too.

As docs say you have to call setTheme before any view output. It seems that super.onCreate() takes part in view processing.

So, to switch between themes dynamically you simply need to call setTheme before super.onCreate like this:

public void onCreate(Bundle savedInstanceState) {
    setTheme(android.R.style.Theme);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
}

If you want to carry on using CSS3 selectors but need to support older browsers I would suggest using a polyfill such as Selectivizr.js

From the Jinja2 template designer documentation:

{% if variable is defined %}
    value of variable: {{ variable }}
{% else %}
    variable is not defined
{% endif %}

We can add "AwaitTerminationSeconds" property for both taskExecutor and taskScheduler as below,

<property name="awaitTerminationSeconds" value="${taskExecutor .awaitTerminationSeconds}" />

<property name="awaitTerminationSeconds" value="${taskScheduler .awaitTerminationSeconds}" />

Documentation for "waitForTasksToCompleteOnShutdown" property says, when shutdown is called

"Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property."

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/concurrent/ExecutorConfigurationSupport.html#setWaitForTasksToCompleteOnShutdown-boolean-

So it is always advised to use waitForTasksToCompleteOnShutdown and awaitTerminationSeconds properties together. Value of awaitTerminationSeconds depends on our application.

I took a slightly different approach than others

static float NextFloat(Random random)
{
    double val = random.NextDouble(); // range 0.0 to 1.0
    val -= 0.5; // expected range now -0.5 to +0.5
    val *= 2; // expected range now -1.0 to +1.0
    return float.MaxValue * (float)val;
}

The comments explain what I'm doing. Get the next double, convert that number to a value between -1 and 1 and then multiply that with float.MaxValue.

Formatter class is also a good option. fmt.format("%.2f", variable); 2 here is showing how many decimals you want. You can change it to 4 for example. Don't forget to close the formatter.

 private static int nJars, nCartons, totalOunces, OuncesTolbs, lbs;

 public static void main(String[] args)
  {
   computeShippingCost();
  }

  public static void computeShippingCost()
  {
   System.out.print("Enter a number of jars: ");
   Scanner kboard = new Scanner (System.in);
   nJars = kboard.nextInt();
   int nCartons = (nJars + 11) / 12;
   int totalOunces = (nJars * 21) + (nCartons * 25);
   int lbs = totalOunces / 16;


   double shippingCost =  ((nCartons * 1.44) + (lbs + 1) * 0.96) + 3.0;

     Formatter fmt = new Formatter();
     fmt.format("%.2f", shippingCost);

   System.out.print("$" + fmt);

   fmt.close();

}

I used a pop over inside a list, Im giving an example via HTML

Even though this question is very old and I stumbled upon it for my own issues with JPA 2.0 and Oracle sequences.

Want to share my research on some of the things -

Relationship between @SequenceGenerator(allocationSize) of GenerationType.SEQUENCE and INCREMENT BY in database sequence definition

Make sure @SequenceGenerator(allocationSize) is set to same value as INCREMENT BY in Database sequence definition to avoid problems (the same applies to the initial value).

For example, if we define the sequence in database with a INCREMENT BY value of 20, set the allocationsize in SequenceGenerator also to 20. In this case the JPA will not make a call to database until it reaches the next 20 mark while it increments each value by 1 internally. This saves database calls to get the next sequence number each time. The side effect of this is - Whenever the application is redeployed or the server is restarted in between, it'll call database to get the next batch and you'll see jumps in the sequence values. Also we need to make sure the database definition and the application setting to be in-sync which may not be possible all the time as both of them are managed by different groups and you can quickly lose control of. If database value is less than the allocationsize, you'll see PrimaryKey constraint errors due to duplicate values of Id. If the database value is higher than the allocationsize, you'll see jumps in the values of Id.

If the database sequence INCREMENT BY is set to 1 (which is what DBAs generally do), set the allocationSize as also 1 so that they are in-sync but the JPA calls database to get next sequence number each time.

If you don't want the call to database each time, use GenerationType.IDENTITY strategy and have the @Id value set by database trigger. With GenerationType.IDENTITY as soon as we call em.persist the object is saved to DB and a value to id is assigned to the returned object so we don't have to do a em.merge or em.flush. (This may be JPA provider specific..Not sure)

Another important thing -

JPA 2.0 automatically runs ALTER SEQUENCE command to sync the allocationSize and INCREMENT BY in database sequence. As mostly we use a different Schema name(Application user name) rather than the actual Schema where the sequence exists and the application user name will not have ALTER SEQUENCE privileges, you might see the below warning in the logs -

000004c1 Runtime W CWWJP9991W: openjpa.Runtime: Warn: Unable to cache sequence values for sequence "RECORD_ID_SEQ". Your application does not have permission to run an ALTER SEQUENCE command. Ensure that it has the appropriate permission to run an ALTER SEQUENCE command.

As the JPA could not alter the sequence, JPA calls database everytime to get next sequence number irrespective of the value of @SequenceGenerator.allocationSize. This might be a unwanted consequence which we need to be aware of.

To let JPA not to run this command, set this value - in persistence.xml. This ensures that JPA will not try to run ALTER SEQUENCE command. It writes a different warning though -

00000094 Runtime W CWWJP9991W: openjpa.Runtime: Warn: The property "openjpa.jdbc.DBDictionary=disableAlterSeqenceIncrementBy" is set to true. This means that the 'ALTER SEQUENCE...INCREMENT BY' SQL statement will not be executed for sequence "RECORD_ID_SEQ". OpenJPA executes this command to ensure that the sequence's INCREMENT BY value defined in the database matches the allocationSize which is defined in the entity's sequence. With this SQL statement disabled, it is the responsibility of the user to ensure that the entity's sequence definition matches the sequence defined in the database.

As noted in the warning, important here is we need to make sure @SequenceGenerator.allocationSize and INCREMENT BY in database sequence definition are in sync including the default value of @SequenceGenerator(allocationSize) which is 50. Otherwise it'll cause errors.

It worked for me this way, it's the best I've found. It is for a max length of 200 characters

editObservations.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        if (editObservations.getText().length() >= 201){
                String str = editObservations.getText().toString().substring(0, 200);
                editObservations.setText(str);
                editObservations.setSelection(str.length());
        }
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
                                          int after) {
    }

    @Override
    public void afterTextChanged(Editable s) {
    }
});

dataGridView1.SelectedRows[0].Index;

For a long time, CMake had the add_definitions command for this purpose. However, recently the command has been superseded by a more fine grained approach (separate commands for compile definitions, include directories, and compiler options).

An example using the new add_compile_definitions:

add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION})
add_compile_definitions(WITH_OPENCV2)

Or:

add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION} WITH_OPENCV2)

The good part about this is that it circumvents the shabby trickery CMake has in place for add_definitions. CMake is such a shabby system, but they are finally finding some sanity.

Find more explanation on which commands to use for compiler flags here: https://cmake.org/cmake/help/latest/command/add_definitions.html

Likewise, you can do this per-target as explained in Jim Hunziker's answer.

If you wrap your form elements in a form tag with a name attribute you can easily get the value using document.formName.radioGroupName.value.

<form name="myForm">
    <input type="radio" id="genderm" name="gender" value="male" />
    <label for="genderm">Male</label>
    <input type="radio" id="genderf" name="gender" value="female" />
    <label for="genderf">Female</label>
</form>

<script>
    var selected = document.forms.myForm.gender.value;
</script>

This works for me

If you migrated .htaccess file from public directory to project folder and altered server.php to index.php in project folder then this should works for you.

Upgrade to PostgreSQL 9.5 or greater. If (not) exists was introduced in version 9.5.

Check first your class loader.

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

if (classLoader == null) {
    classLoader = Class.class.getClassLoader();
}

classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");

// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml

This should fix your problem:

$credentials = New-Object Management.Automation.PSCredential “[email protected]”, (“password” | ConvertTo-SecureString -AsPlainText -Force)

Then use the credential in your call to Send-MailMessage -From $From -To $To -Body $Body $Body -SmtpServer {$smtpServer URI} -Credential $credentials -Verbose -UseSsl

According to the latest pandas documentation you can read a csv file selecting only the columns which you want to read.

import pandas as pd

df = pd.read_csv('some_data.csv', usecols = ['col1','col2'], low_memory = True)

Here we use usecols which reads only selected columns in a dataframe.

We are using low_memory so that we Internally process the file in chunks.

A person might get this while working with factory functions, so I can confirm this is valid syntax:

$user = factory(User::class, 1)->create()->first();

You might see the collection instance error if you do something like:

$user = factory(User::class, 1)->create()->id;

so change it to:

$user = factory(User::class, 1)->create()->first()->id;

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>

This also works though its cheating

def factorial(n):
    x=[]
    if n <= 1:
        return 1
    else:
        for i in range(1,n+1): 
            p*=i
            x.append(p)
        print x[n-1]    

You want sessions if you have data you want to have the data held for longer than one page.

$_GET for just one page.

<a href='page.php?var=data'>Data link</a>

on page.php

<?php
echo $_GET['var'];
?>

will output: data

You can write the following:

Path.Combine(Path.GetParentDirectory(GetType(MyClass).Assembly.Location), "Images\image.jpg")

Try

public bool IsDivisible(int x, int n)
{
   return (x % n) == 0;
}

The modulus operator % returns the remainder after dividing x by n which will always be 0 if x is divisible by n.

For more information, see the % operator on MSDN.

It only worked for me in Firefox when accessing it from the window object.

Example...

window.onload = function()
{
 window.localStorage.clear();
}

I don't see a way to run a single untagged test within a test class but I am providing my workflow since it seems to be useful for anyone who runs into this question.

From within a sbt session:

test:testOnly *YourTestClass

(The asterisk is a wildcard, you could specify the full path com.example.specs.YourTestClass.)

All tests within that test class will be executed. Presumably you're most concerned with failing tests, so correct any failing implementations and then run:

test:testQuick

... which will only execute tests that failed. (Repeating the most recently executed test:testOnly command will be the same as test:testQuick in this case, but if you break up your test methods into appropriate test classes you can use a wildcard to make test:testQuick a more efficient way to re-run failing tests.)

Note that the nomenclature for test in ScalaTest is a test class, not a specific test method, so all untagged methods are executed.

If you have too many test methods in a test class break them up into separate classes or tag them appropriately. (This could be a signal that the class under test is in violation of single responsibility principle and could use a refactoring.)

Use org.mortbay.jetty.handler.ContextHandler. You don't need additional components like StaticServlet.

At the jetty home,

$ cd contexts

$ cp javadoc.xml static.xml

$ vi static.xml

...

<Configure class="org.mortbay.jetty.handler.ContextHandler">
<Set name="contextPath">/static</Set>
<Set name="resourceBase"><SystemProperty name="jetty.home" default="."/>/static/</Set>
<Set name="handler">
  <New class="org.mortbay.jetty.handler.ResourceHandler">
    <Set name="cacheControl">max-age=3600,public</Set>
  </New>
 </Set>
</Configure>

Set the value of contextPath with your URL prefix, and set the value of resourceBase as the file path of the static content.

It worked for me.

Just having final will have the intended effect.

final int x = 5;

...
x = 10; // this will cause a compilation error because x is final

Declaring static is making it a class variable, making it accessible using the class name <ClassName>.x

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

Change your configuration to this (add a slash):

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

Or the solution outlined below (proposed by @absiddiqueLive) will work for any domain:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

If you need to support http and https and preserve the protocol choice try the following:

RewriteRule ^login\$ https://www.%{HTTP_HOST}/login [R=301,L]

Where you replace login with checkout.php or whatever URL you need to support HTTPS on.

I'd argue this is a bad idea though. For the reasoning please read this answer.

I found this while passing and looking for answers on how to compile a set of csvs into a single excel doc with the worksheets (tabs) named after the csv files. It is a nice function. Sadly, I cannot run them on my network :( so i do not know how well it works.

Correct me if I'm mistaken, but the previous example, I believe, is just slightly out of sync with the latest version of James Newton's Json.NET library.

var o = JObject.Parse(stringFullOfJson);
var page = (int)o["page"];
var totalPages = (int)o["total_pages"];

If you're not in an ipython notebook (like the OP), you can also just declare the size when you declare the figure:

width = 12
height = 12
plt.figure(figsize=(width, height))

One of the variables has not been given any value, thus it is a NoneType. You'll have to look into why this is, it's probably a simple logic error on your part.

Per screenshot, in Eclipse select "run as" then "Run Configurations..." and add the answer from Trevor Robinson with double quotes instead of quotes. If you miss the double quotes you'll get "could not find or load main class" errors.

Update your google play services or just create the new emulator. When you install the new emulator this problem will automatically be solved. Happy coding :)

Yes. Try:

class USBDevice : GenericDevice, IOurDevice

Note: The base class should come before the list of interface names.

Of course, you'll still need to implement all the members that the interfaces define. However, if the base class contains a member that matches an interface member, the base class member can work as the implementation of the interface member and you are not required to manually implement it again.

Add some css either in the head or in a external document. asp:TextBox are rendered as input :

input {
     width:100%;
}

Your html should look like : http://jsfiddle.net/c5WXA/

Note this will affect all your textbox : if you don't want this, give the containing div a class and specify the css.

.divClass input {
     width:100%;
}

I don't know why @Paul's reply is downvoted, but the validation against null is a good choice. Maybe a more affirmative example will make better sense:

In JavaScript a missed parameter is like a declared variable that is not initialized (just var a1;). And the equality operator converts the undefined to null, so this works great with both value types and objects, and this is how CoffeeScript handles optional parameters.

function overLoad(p1){
    alert(p1 == null); // Caution, don't use the strict comparison: === won't work.
    alert(typeof p1 === 'undefined');
}

overLoad(); // true, true
overLoad(undefined); // true, true. Yes, undefined is treated as null for equality operator.
overLoad(10); // false, false


function overLoad(p1){
    if (p1 == null) p1 = 'default value goes here...';
    //...
}

Though, there are concerns that for the best semantics is typeof variable === 'undefined' is slightly better. I'm not about to defend this since it's the matter of the underlying API how a function is implemented; it should not interest the API user.

I should also add that here's the only way to physically make sure any argument were missed, using the in operator which unfortunately won't work with the parameter names so have to pass an index of the arguments.

function foo(a, b) {
    // Both a and b will evaluate to undefined when used in an expression
    alert(a); // undefined
    alert(b); // undefined

    alert("0" in arguments); // true
    alert("1" in arguments); // false
}

foo (undefined);

Preprocess your input CSV to replace blank entries with \N.

Attempt at a regex: s/,,/,\n,/g and s/,$/,\N/g

Good luck.

The right approach is to use setImageViewUri() (slower) or the setImageViewBitmap() and recreating RemoteViews every time you update the notification.

One more plugin, to play notification sounds on websites: Ion.Sound

• Basic Demo
• Advanced Demo
• Ion.Sound GitHub Page

Advantages:

• JavaScript-plugin for playing sounds based on Web Audio API with fallback to HTML5 Audio.
• Plugin is working on most popular desktop and mobile browsers and can be used everywhere, from common web sites to browser games.
• Audio-sprites support included.
• No dependecies (jQuery not required).
• 25 free sounds included.

Set up plugin:

// set up config
ion.sound({
    sounds: [
        {
            name: "my_cool_sound"
        },
        {
            name: "notify_sound",
            volume: 0.2
        },
        {
            name: "alert_sound",
            volume: 0.3,
            preload: false
        }
    ],
    volume: 0.5,
    path: "sounds/",
    preload: true
});

// And play sound!
ion.sound.play("my_cool_sound");

I tried to manage using the below command. This will write the output in log file as well as print on console.

#!/bin/bash

# Log Location on Server.
LOG_LOCATION=/home/user/scripts/logs
exec > >(tee -i $LOG_LOCATION/MylogFile.log)
exec 2>&1

echo "Log Location should be: [ $LOG_LOCATION ]"

Please note: This is bash code so if you run it using sh it will through syntax error

Tried most of the above and nothing worked. Then turned off the VPN software (NordVPN) and everything was fine.

Jefferson is right, you have to do it backwards.

Here's the c# equivalent:

for (var i == list.Items.Count - 1; i >= 0; i--)
{
    list.Items.RemoveAt(i);
}

It's hard to tell exactly what you're after, but something like this should get you started:

with open ("data.txt", "r") as myfile:
    data = ' '.join([line.replace('\n', '') for line in myfile.readlines()])

First of all, I don't really see why you would want an object having only ID and Version, and all other props to be nulls. However, here is some code which will do that for you (which doesn't use JPA Em, but normal Hibernate. I assume you can find the equivalence in JPA or simply obtain the Hibernate Session obj from the em delegate Accessing Hibernate Session from EJB using EntityManager ):

List<T> results = session.createCriteria(entityClazz)
    .setProjection( Projections.projectionList()
        .add( Property.forName("ID") )
        .add( Property.forName("VERSION") )
    )
    .setResultTransformer(Transformers.aliasToBean(entityClazz); 
    .list();

This will return a list of Objects having their ID and Version set and all other props to null, as the aliasToBean transformer won't be able to find them. Again, I am uncertain I can think of a situation where I would want to do that.

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

One way to do that would be to write a root reducer in your application.

The root reducer would normally delegate handling the action to the reducer generated by combineReducers(). However, whenever it receives USER_LOGOUT action, it returns the initial state all over again.

For example, if your root reducer looked like this:

const rootReducer = combineReducers({
  /* your app’s top-level reducers */
})

You can rename it to appReducer and write a new rootReducer delegating to it:

const appReducer = combineReducers({
  /* your app’s top-level reducers */
})

const rootReducer = (state, action) => {
  return appReducer(state, action)
}

Now we just need to teach the new rootReducer to return the initial state after USER_LOGOUT action. As we know, reducers are supposed to return the initial state when they are called with undefined as the first argument, no matter the action. Let’s use this fact to conditionally strip the accumulated state as we pass it to appReducer:

 const rootReducer = (state, action) => {
  if (action.type === 'USER_LOGOUT') {
    state = undefined
  }

  return appReducer(state, action)
}

Now, whenever USER_LOGOUT fires, all reducers will be initialized anew. They can also return something different than they did initially if they want to because they can check action.type as well.

To reiterate, the full new code looks like this:

const appReducer = combineReducers({
  /* your app’s top-level reducers */
})

const rootReducer = (state, action) => {
  if (action.type === 'USER_LOGOUT') {
    state = undefined
  }

  return appReducer(state, action)
}

Note that I’m not mutating the state here, I am merely reassigning the reference of a local variable called state before passing it to another function. Mutating a state object would be a violation of Redux principles.

In case you are using redux-persist, you may also need to clean your storage. Redux-persist keeps a copy of your state in a storage engine, and the state copy will be loaded from there on refresh.

First, you need to import the appropriate storage engine and then, to parse the state before setting it to undefined and clean each storage state key.

const rootReducer = (state, action) => {
    if (action.type === SIGNOUT_REQUEST) {
        // for all keys defined in your persistConfig(s)
        storage.removeItem('persist:root')
        // storage.removeItem('persist:otherKey')

        state = undefined;
    }
    return appReducer(state, action);
};

This is what I came up with. Here is a fiddle.

First, I need three wrapper elements for both a square shape and centered text.

<div><div><div>Lorem ipsum dolor sit amet, consectetuer adipiscing elit,
sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat
volutpat.</div></div></div>

This is the stylecheet. It makes use of two techniques, one for square shapes and one for centered text.

body > div {
    position:relative;
    height:0;
    width:50%; padding-bottom:50%;
}

body > div > div {
    position:absolute; top:0;
    height:100%; width:100%;
    display:table;
    border:1px solid #000;
    margin:1em;
}

body > div > div > div{
    display:table-cell;
    vertical-align:middle; text-align:center;
    padding:1em;
}

Case #1

1. Not necessarily, there are other places in the pipeline to modify the response (action filters, message handlers).
2. See above -- but if the action returns a domain model, then you can't modify the response inside the action.

Cases #2-4

1. The main reasons to throw HttpResponseException are:
   • if you are returning a domain model but need to handle error cases,
   • to simplify your controller logic by treating errors as exceptions

2. These should be equivalent; HttpResponseException encapsulates an HttpResponseMessage, which is what gets returned back as the HTTP response.

   e.g., case #2 could be rewritten as

   public HttpResponseMessage Get(string id)
   {
       HttpResponseMessage response;
       var customer = _customerService.GetById(id);
       if (customer == null)
       {
           response = new HttpResponseMessage(HttpStatusCode.NotFound);
       }
       else
       {
           response = Request.CreateResponse(HttpStatusCode.OK, customer);
           response.Content.Headers.Expires = new DateTimeOffset(DateTime.Now.AddSeconds(300));
       }
       return response;
   }
   

   ... but if your controller logic is more complicated, throwing an exception might simplify the code flow.

3. HttpError gives you a consistent format for the response body and can be serialized to JSON/XML/etc, but it's not required. e.g., you may not want to include an entity-body in the response, or you might want some other format.

Here is additional information for other answers.

Since Android has

GPS_PROVIDER and NETWORK_PROVIDER

you can register to both and start fetch events from onLocationChanged(Location location) from two at the same time. So far so good. Now the question do we need two results or we should take the best. As I know GPS_PROVIDER results have better accuracy than NETWORK_PROVIDER.

Let's define Location field:

private Location currentBestLocation = null;

Before we start listen on Location change we will implement the following method. This method returns the last known location, between the GPS and the network one. For this method newer is best.

/**
 * @return the last know best location
 */
private Location getLastBestLocation() {
    Location locationGPS = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    Location locationNet = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    long GPSLocationTime = 0;
    if (null != locationGPS) { GPSLocationTime = locationGPS.getTime(); }

    long NetLocationTime = 0;

    if (null != locationNet) {
        NetLocationTime = locationNet.getTime();
    }

    if ( 0 < GPSLocationTime - NetLocationTime ) {
        return locationGPS;
    }
    else {
        return locationNet;
    }
}

Each time when we retrieve a new location we will compare it with our previous result.

...
static final int TWO_MINUTES = 1000 * 60 * 2;
...

I add a new method to onLocationChanged:

@Override
public void onLocationChanged(Location location) {

    makeUseOfNewLocation(location);

    if(currentBestLocation == null){
        currentBestLocation = location;
    }

    ....
}


/**
 * This method modify the last know good location according to the arguments.
 *
 * @param location The possible new location.
 */
void makeUseOfNewLocation(Location location) {
    if ( isBetterLocation(location, currentBestLocation) ) {
        currentBestLocation = location;
    }
}

....

/** Determines whether one location reading is better than the current location fix
 * @param location  The new location that you want to evaluate
 * @param currentBestLocation  The current location fix, to which you want to compare the new one.
 */
protected boolean isBetterLocation(Location location, Location currentBestLocation) {
    if (currentBestLocation == null) {
        // A new location is always better than no location
        return true;
    }

    // Check whether the new location fix is newer or older
    long timeDelta = location.getTime() - currentBestLocation.getTime();
    boolean isSignificantlyNewer = timeDelta > TWO_MINUTES;
    boolean isSignificantlyOlder = timeDelta < -TWO_MINUTES;
    boolean isNewer = timeDelta > 0;

    // If it's been more than two minutes since the current location, use the new location,
    // because the user has likely moved.
    if (isSignificantlyNewer) {
        return true;
        // If the new location is more than two minutes older, it must be worse.
    } else if (isSignificantlyOlder) {
        return false;
    }

    // Check whether the new location fix is more or less accurate
    int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy());
    boolean isLessAccurate = accuracyDelta > 0;
    boolean isMoreAccurate = accuracyDelta < 0;
    boolean isSignificantlyLessAccurate = accuracyDelta > 200;

    // Check if the old and new location are from the same provider
    boolean isFromSameProvider = isSameProvider(location.getProvider(),
                                                currentBestLocation.getProvider());

    // Determine location quality using a combination of timeliness and accuracy
    if (isMoreAccurate) {
        return true;
    } else if (isNewer && !isLessAccurate) {
        return true;
    } else if (isNewer && !isSignificantlyLessAccurate && isFromSameProvider) {
        return true;
    }
    return false;
}

// Checks whether two providers are the same
private boolean isSameProvider(String provider1, String provider2) {
    if (provider1 == null) {
        return provider2 == null;
    }
    return provider1.equals(provider2);
}

....

For Access 2013, you could just do

Sendkeys "%fic"

This is the same as typing ALT, F, I, C on your keyboard.

It's probably a different sequence of letters for different versions, but the "%" symbol means "ALT", so keep that in the code. you may just need to change the letters, depending on what letters appear when you press ALT

Letters that appear when pressing ALT in Access 2013

As mentioned in other answers, doubles can have small deviations. And you could write your own method to compare them using an "acceptable" deviation. However ...

There is an apache class for comparing doubles: org.apache.commons.math3.util.Precision

It contains some interesting constants: SAFE_MIN and EPSILON, which are the maximum possible deviations of simple arithmetic operations.

It also provides the necessary methods to compare, equal or round doubles. (using ulps or absolute deviation)

You have to specify Resource for the bucket via "arn:aws:s3:::bucketname" or "arn:aws:3:::bucketname*". The latter is preferred since it allows manipulations on the bucket's objects too. Notice there is no slash!

Listing objects is an operation on Bucket. Therefore, action "s3:ListBucket" is required. Adding an object to the Bucket is an operation on Object. Therefore, action "s3:PutObject" is needed. Certainly, you may want to add other actions as you require.

{
"Version": "version_id",
"Statement": [
    {
        "Sid": "some_id",
        "Effect": "Allow",
        "Action": [
            "s3:ListBucket",
            "s3:PutObject"
        ],
        "Resource": [
            "arn:aws:s3:::bucketname*"
        ]
    }
] 
}

UPDATE 2015:

Graph API v2.0 can't be queried using usernames, you should use userId always.

In classic mode IIS works h ISAPI extensions and ISAPI filters directly. And uses two pipe lines , one for native code and other for managed code. You can simply say that in Classic mode IIS 7.x works just as IIS 6 and you dont get extra benefits out of IIS 7.x features.

In integrated mode IIS and ASP.Net are tightly coupled rather then depending on just two DLLs on Asp.net as in case of classic mode.

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

Check out the library angular-cache if you like $http's built-in caching but want more control. You can use it to seamlessly augment $http cache with time-to-live, periodic purges, and the option of persisting the cache to localStorage so that it's available across sessions.

FWIW, it also provides tools and patterns for making your cache into a more dynamic sort of data-store that you can interact with as POJO's, rather than just the default JSON strings. Can't comment on the utility of that option as yet.

(Then, on top of that, related library angular-data is sort of a replacement for $resource and/or Restangular, and is dependent upon angular-cache.)

The problem I had accessing the sqlite db file I created in my java (jersey) server had solely to due with path. Some of the docs say the jdbc connect url should look like "jdbc:sqlite://path-to-file/sample.db". I thought the double-slash was part of a htt protocol-style path and would map properly when deployed, but in actuality, it's an absolute or relative path. So, when I placed the file at the root of the WebContent folder (tomcat project), a uri like this worked "jdbc:sqlite:sample.db".

The one thing that was throwing me was that when I was stepping through the debugger, I received a message that said "opening db: ... permission denied". I thought it was a matter of file system permissions or perhaps sql user permissions. After finding out that SQLite doesn't have the concept of roles/permissions like MySQL, etc, I did eventually change the file permissions before I came to what I believe was the correct solution, but I think it was just a bad message (i.e. permission denied, instead of File not found).

Hope this helps someone.

I used this in all my view controllers, it's simple. Add this lines in all your viewDidLoad methods:

- (void)viewDidLoad{
    //add this 2 lines:
    if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
        self.edgesForExtendedLayout = UIRectEdgeNone;

    [super viewDidLoad];
}

static variables are specific to a class . Constructors initialize attributes ESPECIALY for an instance.

After doing an insert into a table with an identity column, you can reference @@IDENTITY to get the value: http://msdn.microsoft.com/en-us/library/aa933167%28v=sql.80%29.aspx

Just for fun, a shell (almost any shell) implementation:

#!/bin/sh
gcd() {   # Calculate $1 % $2 until $2 becomes zero.
      until [ "$2" -eq 0 ]; do set -- "$2" "$(($1%$2))"; done
      echo "$1"
      }

lcm() {   echo "$(( $1 / $(gcd "$1" "$2") * $2 ))";   }

while [ $# -gt 1 ]; do
    t="$(lcm "$1" "$2")"
    shift 2
    set -- "$t" "$@"
done
echo "$1"

try it with:

$ ./script 2 3 4 5 6

to get

60

The biggest input and result should be less than (2^63)-1 or the shell math will wrap.

Try this

@echo off
setlocal enableextensions enabledelayedexpansion
set firstLine=1
for /f "delims=" %%i in (yourfilename.txt) do (
    if !firstLine!==1 echo %%i
    set firstLine=0
)
endlocal

GUID has longstanding usage in areas where it isn't necessarily a 128-bit value in the same way as a UUID. For example, the RSS specification defines GUIDs to be any string of your choosing, as long as it's unique, with an "isPermalink" attribute to specify that the value you're using is just a permalink back to the item being syndicated.

I've had this problem before. Figured out I had another application using the same port (3000).

Easy way to find this out:

In the terminal, type netstat -a -p TCP -n | grep 3000 (substitute the port you're using for the '3000'). If there is more than one listening, something else is already occupying that port. You should stop that process or change the port for your new process.

You could also use jOOL library - https://github.com/jOOQ/jOOL

It has already prepared function interfaces with different number of parameters. For instance, you could use org.jooq.lambda.function.Function3, etc from Function0 up to Function16.

Thanks to all this replies + some trial and errors, I managed to install it on a Mac with clang. So just sharing my solution in case it is useful to someone.

1. Follow the instructions on Documentation - Installing TensorFlow from Sources

2. When prompted for

   Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]

then copy-paste this string:

-mavx -mavx2 -mfma -msse4.2

(The default option caused errors, so did some of the other flags. I got no errors with the above flags. BTW I replied n to all the other questions)

After installing, I verify a ~2x to 2.5x speedup when training deep models with respect to another installation based on the default wheels - Installing TensorFlow on macOS

Hope it helps

Not the most elegant, but I do (for Python 3):

if hasattr(instance, '__iter__') and not isinstance(instance, (str, bytes)):
    ...

This allows other iterables (like Django querysets) but excludes strings and bytestrings. I typically use this in functions that accept either a single object ID or a list of object IDs. Sometimes the object IDs can be strings and I don't want to iterate over those character by character. :)

In a webpage where I wanted a in image to scale with browser size change and remain at the top, next to a fixed div, all I had to do was use a single CSS line: overflow:hidden; and it did the trick. The image scales perfectly.

What is especially nice is that this is pure css and will work even if Javascript is turned off.

CSS:

#ImageContainerDiv {
  overflow: hidden;
}

HTML:

<div id="ImageContainerDiv">
  <a href="URL goes here" target="_blank">
    <img src="MapName.png" alt="Click to load map" />
  </a>
</div>

I had the same problem for gitlab CI running node:lts image:

• I just restarted the docker daemon and restart the container, it worked for me.

var str = "Lorem ipsum <pre>text 1</pre> Lorem ipsum <pre>text 2</pre>";_x000D_
    str.replace(/<pre>(.*?)<\/pre>/g, function(match, g1) { console.log(g1); });

Since accepted answer is without javascript code, so adding that:

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

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

move $s0, $zero
li   $s0, 0

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

li $s0, 12345678

Here is what needs to go in D1: =VLOOKUP(C1, $A$1:$B$4, 2, FALSE)

You should then be able to copy this down to the rest of column D.

In some rarer occasions, check that the project can be built using regular npm commands. I ran into one that is configured to work with bower, so bower install <github_url> works while npm install <github_url> gives that unhelpful cryptic error message on all platforms...

You need to create new TextNodes as well as td nodes for each column, not reuse them among all of the columns as your code is doing.

Edit: Revise your code like so:

for (var i = 1; i < 4; i++)
{
   tr[i] = document.createElement('tr');   
      var td1 = document.createElement('td');
      var td2 = document.createElement('td');
      td1.appendChild(document.createTextNode('Text1'));
      td2.appendChild(document.createTextNode('Text2'));
      tr[i].appendChild(td1);
      tr[i].appendChild(td2);
  table.appendChild(tr[i]);
}

See this: Demo

$('#cat_icon,.panel_title').click(function () {
   $('#categories,#cat_icon').stop().slideToggle('slow');
});

Path of least resistance:

• Have a simple web project in mind.
• Go to rubyonrails.org and look at their "Blog in 15 minutes" screencast to get excited.
• Get a copy of O'Reilly Media's Learning Ruby
• Get a Mac or Linux box.
  (Fewer early Rails frustrations due to the fact that Rails is generally developed on these.)
• Get a copy of Agile Web Development with Rails.
• Get the version of Ruby and Rails described in that book.
• Run through that book's first section to get a feel for what it's like.
• Go to railscasts.com and view at the earliest videos for a closer look.
• Buy The Rails Way by Obie Fernandez to get a deeper understanding of Rails and what it's doing.
• Then upgrade to the newest production version of Rails, and view the latest railscasts.com videos.

var mystring = "abc ab a";
var re  = new RegExp("ab"); // any regex here

if ( re.exec(mystring) != null ){ 
   alert("matches"); // true in this case
}

Use standard regular expressions:

var re  = new RegExp("^ab");  // At front
var re  = new RegExp("ab$");  // At end
var re  = new RegExp("ab(c|d)");  // abc or abd

I am not a coder, but you could save a few lines:

<div>
            <select onchange="if(selectedIndex!=0)document.getElementById('less_is_more').innerHTML=options[selectedIndex].value;">
                <option value="">hire me for real estate</option>
                <option value="me!!!">Who is a good Broker? </option>
                <option value="yes!!!">Can I buy a house with no down payment</option>
                <option value="send me a note!">Get my contact info?</option>
            </select>
        </div>

<div id="less_is_more"></div>

Here is demo.

1. No you don’t need quotes.

2. Yes you can. But note that relative URLs are resolved from the URL of your stylesheet.

3. Better don’t use quotes. I think there are clients that don’t understand them.

In case you are using eclipse to connect oracle without SID. There are two drivers to select i.e., Oracle thin driver and other is other driver. Select other drivers and enter service name in database column. Now you can connect directly using service name without SID.

<http pattern="/resources/**" security="none"/>

Or with Java configuration:

web.ignoring().antMatchers("/resources/**");

Instead of the old:

 <intercept-url pattern="/resources/**" filters="none"/>

for exp . disable security for a login page :

  <intercept-url pattern="/login*" filters="none" />

Here is a runnable example using the mentioned indeterminate attribute:

const indeterminates = document.getElementsByClassName('indeterminate');_x000D_
indeterminates['0'].indeterminate  = true;

<form>_x000D_
  <div>_x000D_
    <input type="checkbox" checked="checked" />True_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" />False_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" class="indeterminate" />Indeterminate_x000D_
  </div>_x000D_
</form>

Just run the code snippet to see how it looks like.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

There is a magical function PHP is offering to you it called in_array().

Using parts of your code we will modify the loop as follows:

<?php
$array = array(12,43,66,21,56,43,43,78,78,100,43,43,43,21);
$arr2 = array();
$counter = 0;
for($arr = 0; $arr < count($array); $arr++){
    if (in_array($array[$arr], $arr2)) {
        ++$counter;
        continue;
    }
    else{
        $arr2[] = $array[$arr];
    }
}
echo 'number of duplicates: '.$counter;
print_r($arr2);
?>

The above code snippet will return the number total number of repeated items i.e. form the sample array 43 is repeated 5 times, 78 is repeated 1 time and 21 is repeated 1 time, then it returns an array without repeat.

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

You can use SSH and SFTP as suggested here.

1. In the Guest OS (Mac OS X), open System Preferences > Sharing, then activate Remote Login; note the ip address specified in the Remote Login instructions, e.g. ssh [email protected]
2. In VirtualBox, open Devices > Network > Network Settings > Advanced > Port Forwarding and specify Host IP = 127.0.0.1, Host Port 2222, Guest IP 10.0.2.15, Guest Port 22
3. On the Host OS, run the following command sftp -P 2222 [email protected]; if you prefer a graphical interface, you can use FileZilla

Replace user and 10.0.2.15 with the appropriate values relevant to your configuration.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

I had similar situation like Hobhouse. I wanted to use command

 ssh myhost.com 'some_command'

and 'some_command' exists in '/var/some_location' so I tried to append '/var/some_location' in PATH environment by editing '$HOME/.bashrc'

but that wasn't working. because default .bashrc(Ubuntu 10.4 LTS) prevent from sourcing by code like below

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

so If you want to change environment for ssh non-login shell. you should add code above that line.

Many times, we need to hide some parts of codes while writing a long code.

Example: - Just on clicking "Code show/hide", we can hide 3 lines of codes.

So here is the function that you need to define for partially hiding few part of codes and then call it whenever you want to hide some code:

from IPython.display import HTML

def hide_toggle(for_next=False):
    this_cell = """$('div.cell.code_cell.rendered.selected')""" ; next_cell = this_cell + '.next()';
    toggle_text = 'Code show/hide'  # text shown on toggle link
    target_cell = this_cell ;  js_hide_current = '' 

    if for_next:
        target_cell = next_cell; toggle_text += ' next cell';
        js_hide_current = this_cell + '.find("div.input").hide();'
    js_f_name = 'code_toggle_{}'.format(str(random.randint(1,2**64)))

    html = """<script>
            function {f_name}() {{{cell_selector}.find('div.input').toggle(); }}
            {js_hide_current}
        </script>
        <a href="javascript:{f_name}()">{toggle_text}</a>
    """.format(f_name=js_f_name,cell_selector=target_cell,js_hide_current=js_hide_current, toggle_text=toggle_text )
    return HTML(html)

Once we are ready with function definition, our next task is very easy. Just we need to call the function to hide/show the code.

print("Function for hiding the cell")
hide_toggle()

Just index using you ind_pos

ind_pos = [1,5,7]
print (a[ind_pos]) 
[88 85 16]


In [55]: a = [0,88,26,3,48,85,65,16,97,83,91]

In [56]: import numpy as np

In [57]: arr = np.array(a)

In [58]: ind_pos = [1,5,7]

In [59]: arr[ind_pos]
Out[59]: array([88, 85, 16])

Just try to create the marker and set the draggable property to true. The code will be something as follows:

Marker = new google.maps.Marker({
    position: latlon,
    map: map,            
    draggable: true,
    title: "Drag me!"
});

I hope this helps!

You get Constant expression required because you left the values off your constants. Try:

public abstract class Foo {
    ...
    public static final int BAR=0;
    public static final int BAZ=1;
    public static final int BAM=2;
    ...
}

Try the following statement:

select  distinct A.[Tag],
     count(A.[Tag]) as TAG_COUNT,
     (SELECT count(*) FROM [TagTbl] AS B WHERE A.[Tag]=B.[Tag] AND B.[ID]>0)
     from [TagTbl] AS A GROUP BY A.[Tag]

The first field will be the tag the second will be the whole count the third will be the positive ones count.

First of all, you're testing fp twice. so printf("Error Reading File\n"); never gets executed.

Then, the output of fscanf should be equal to 2 since you're reading two values.

By your tags, I'm assuming your using Github. Why not create some branch protection rules for your master branch? That way even if you do try to push to master, it will reject it.

1) Go to the 'Settings' tab of your repo on Github.

2) Click on 'Branches' on the left side-menu.

3) Click 'Add rule'

4) Enter 'master' for a branch pattern.

5) Check off 'Require pull request reviews before merging'

I would also recommend doing the same for your dev branch.

I found this very difficult to get an answer to but eventually figured it out. So I will write the steps below.

1. Before you setup your connection string in code, ensure you actually can access your database. Start obviously by logging into the database server using SSMS (Sql Server Management Studio or it's equivalent in other databases) locally to ensure you have access using whatever details you intend to use.

2. Next (if needed), if you are trying to access the database on a separate server, ensure you can do likewise in SSMS. So setup SSMS on a computer and ensure you can access the server with the username and password to that database server.

If you don't get the above 2 right, you are simply wasting your time as you cant access the database. This can either be because the user you setup is wrong, doesn't have remote access enabled (if needed), or the ports are not opened (if needed), among many other reasons but these being the most common.

Once you have verified that you can access the database using SSMS. The next step, just for the sake of automating the process and avoiding mistakes, is to let the system do the work for you.

3. Start up an empty project, add your choice of Linq to SQL or Dataset (EF is good but the connection string is embedded inside of an EF con string, I want a clean one), and connect to your database using the details verified above in the con string wizzard. Add any table and save the file.

Now go into the web config, and magically, you will see nice clean working connection string there with all the details you need.

{ Below was part of an old post so you can ignore this, I leave it in for reference as its the most basic way to access the database from only code behind. Please scroll down and continue from step 2 below. }

Lets assume the above steps start you off with something like the following as your connection string in the code behind:

string conString = "Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;";

This step is very important. Make sure you have the above format of connection string working before taking the following steps. Make sure you actually can access your data using some form of sql command text which displays some data from a table in labels or text boses or whatever, as this is the simplest way to do a connection string.

Once you are sure the above style works its now time to take the next steps:

1. Export your string literal (the stuff in the quotes, including the quotes) to the following section of the web.config file (for multiple connection strings, just do multiple lines:

<configuration>
    <connectionStrings>
        <add name="conString" connectionString="Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
        <add name="conString2" connectionString="Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
        <add name="conString3" connectionString="Data Source=localhost;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
    </connectionStrings>
</configuration>

{ The above was part of an old post, after doing the top 3 steps this whole process will be done for you, so you can ignore it. I just leave it here for my own reference. }

2. Now add the following line of code to the C# code behind, prefrably just under the class definition (i.e. not inside a method). This points to the root folder of your project. Essentially it is the project name. This is usually the location of the web.config file (in this case my project is called MyProject.

static Configuration rootWebConfig = WebConfigurationManager.OpenWebConfiguration("/MyProject");

3. Now add the following line of code to the C# code behind. This sets up a string constant to which you can refer in many places throughout your code should you need a conString in different methods.

const string CONSTRINGNAME = "conString";

4. Next add the following line of code to the C# code behind. This gets the connection string from the web.config file with the name conString (from the constant above)

ConnectionStringSettings conString = rootWebConfig.ConnectionStrings.ConnectionStrings[CONSTRINGNAME];

5. Finally, where you origionally would have had something similar to this line of code:

SqlConnection con = new SqlConnection(conString)

you will replace it with this line of code:

SqlConnection con = new SqlConnection(conString.ConnectionString)

After doing these 5 steps your code should work as it did before. Hense the reason you test the constring first in its origional format so you know if it is a problem with the connection string or if it is a problem with the code.

I am new to C#, ASP.Net and Sql Server. So I am sure there must be a better way to do this code. I also would appreicate feedback on how to improve these steps if possible. I have looked all over for something like this but I eventually figured it out after many weeks of hard work. Looking at it myself, I still think, there must be an easier way.

I hope this is helpful.

With Ruby:

ruby -e "File.read('file.txt').split.inject(0){|mem, obj| mem += obj.to_f}"

FWIW, you can pass a table name to useful system SP's like this, should you wish to explore a database that way :

DECLARE @Table sysname; SET @Table = 'TableName';
EXEC sp_fkeys @Table;
EXEC sp_help @Table;

The actually correct and convenient answer for python 3:

>>> import codecs
>>> myString = "spam\\neggs"
>>> print(codecs.escape_decode(bytes(myString, "utf-8"))[0].decode("utf-8"))
spam

>>> myString = "naïve \\t test"

naïve    test

Details regarding codecs.escape_decode:

• codecs.escape_decode is a bytes-to-bytes decoder
• codecs.escape_decode decodes ascii escape sequences, such as: b"\\n" -> b"\n", b"\\xce" -> b"\xce".
• codecs.escape_decode does not care or need to know about the byte object's encoding, but the encoding of the escaped bytes should match the encoding of the rest of the object.

Background:

• @rspeer is correct: unicode_escape is the incorrect solution for python3. This is because unicode_escape decodes escaped bytes, then decodes bytes to unicode string, but receives no information regarding which codec to use for the second operation.
• @Jerub is correct: avoid the AST or eval.
• I first discovered codecs.escape_decode from this answer to "how do I .decode('string-escape') in Python3?". As that answer states, that function is currently not documented for python 3.

The Actual solution of this problem is changing first line in web.php

Just replace Welcome route with following route

Route::view('/', 'welcome');

If still getting same error than you probab

It's been said elaborately, just as "the short answer":

• static variable (class)
  lifetime = program runtime (1)
  visibility = determined by access modifiers (private/protected/public)

• static variable (global scope)
  lifetime = program runtime (1)
  visibility = the compilation unit it is instantiated in (2)

• heap variable
  lifetime = defined by you (new to delete)
  visibility = defined by you (whatever you assign the pointer to)

• stack variable
  visibility = from declaration until scope is exited
  lifetime = from declaration until declaring scope is exited

(1) more exactly: from initialization until deinitialization of the compilation unit (i.e. C / C++ file). Order of initialization of compilation units is not defined by the standard.

(2) Beware: if you instantiate a static variable in a header, each compilation unit gets its own copy.

If you need to update the value in a particular table:

UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');

where

  TABLE-NAME         - The name of the table being updated
  COLUMN-NAME        - The name of the column being updated
  STRING-TO-REPLACE  - The value to replace
  REPLACEMENT-STRING - The replacement

This piece of code may help..

#include <bits/stdc++.h>
using namespace std;    

class node{
public:
    int age;
    string name;
    node(int a, string b){
        age = a;
        name = b;
    }
};

bool operator<(const node& a, const node& b) {

    node temp1=a,temp2=b;
    if(a.age != b.age)
        return a.age > b.age;
    else{
        return temp1.name.append(temp2.name) > temp2.name.append(temp1.name);
    }
}

int main(){
    priority_queue<node> pq;
    node b(23,"prashantandsoon..");
    node a(22,"prashant");
    node c(22,"prashantonly");
    pq.push(b);
    pq.push(a);
    pq.push(c);

    int size = pq.size();
    for (int i = 0; i < size; ++i)
    {
        cout<<pq.top().age<<" "<<pq.top().name<<"\n";
        pq.pop();
    }
}

Output:

22 prashantonly
22 prashant
23 prashantandsoon..

Part of the answer to 'handle' the 'Sequence has no elements' Exception in VB is to test for empty

If Not (myMap Is Nothing) Then
' execute code
End if

Where MyMap is the sequence queried returning empty/null. FYI

I saw this post at least twice, because the accepted answer is hard to remeber for me(I rarely use z or j flags and they are seems not platform independant).

The standard never says clearly the exact data length of size_t, so I suggest you should first check the length size_t on your platform then select one of them:

if sizeof(size_t) == 4 use PRIu32
if sizeof(size_t) == 8 use PRIu64

And I suggest using stdint types instead of raw data types for consistancy.

Creating the file in the Default path did not work for me as the Menu.sublime-menu file has overridden almost all other menu options and left me with only the custom one.

What worked for me is creating the below file in path ~/Library/Application Support/Sublime Text 3/Packages/User/Main.sublime-menu (note directory User instead of Default):

                    { "command": "open_recent_file", "args": {"index": 50 } }
                ]
            }
        ]
    }
]

Result:

Jquery or Javascipt doesn't provide a built-in method to achieve this.

CSS test transform (text-transform:capitalize;) doesn't really capitalize the string's data but shows a capitalized rendering on the screen.

If you are looking for a more legit way of achieving this in the data level using plain vanillaJS, use this solution =>

var capitalizeString = function (word) {    
    word = word.toLowerCase();
    if (word.indexOf(" ") != -1) { // passed param contains 1 + words
        word = word.replace(/\s/g, "--");
        var result = $.camelCase("-" + word);
        return result.replace(/-/g, " ");
    } else {
    return $.camelCase("-" + word);
    }
}

Here's another way:

{

      Sub find_test2()

            alpha_col = "A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,W,Z" 
            MsgBox Split(alpha_col, ",")(ActiveCell.Column - 1) 

      End Sub

}

You can just pass your URL,

NSURL *url = [NSURL URLWithString:@"http://www.myurl.com/1.png"];
NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData * _Nullable data,    NSURLResponse * _Nullable response, NSError * _Nullable error) {
    if (data) {
        UIImage *image = [UIImage imageWithData:data];
        if (image) {
            dispatch_async(dispatch_get_main_queue(), ^{
                    yourimageview.image = image;
            });
        }
    }
}];
[task resume];

Try this another way:

var qry = Employees
          .OrderByDescending (s => s.EmpFName)
          .ThenBy (s => s.Address)
          .Select (s => s.EmpCode);

Queryable.ThenBy

I had the same problem recently and this helped me:

    header('Content-Description: File Transfer'); 
    header('Content-Type: application/octet-stream'); 
    header('Content-Disposition: attachment; filename="FILENAME"'); 
    header('Content-Transfer-Encoding: binary'); 
    header('Expires: 0'); 
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); 
    header('Pragma: public'); 
    header('Content-Length: ' . filesize("PATH/TO/FILE")); 
    ob_clean(); 
    flush(); 
    readfile(PATH/TO/FILE);      
    exit();

I found this answer here

If you do not mind having to compile/generate the file then you could use a pre processing technique. This gives you the power of the generate but results in a clean Verilog file which is often easier to debug and leads to less simulator issues.

I use RubyIt to generate verilog files from templates using ERB (Embedded Ruby).

parameter ROWBITS = <%= ROWBITS %> ;
always @(posedge sysclk) begin
  <% (0...ROWBITS).each do |addr| -%>
    temp[<%= addr %>] <= 1'b0;
  <% end -%>
end

Generating the module_name.v file with :

$ ruby_it --parameter ROWBITS=4 --outpath ./ --file ./module_name.rv

The generated module_name.v

parameter ROWBITS = 4 ;
always @(posedge sysclk) begin
  temp[0] <= 1'b0;
  temp[1] <= 1'b0;
  temp[2] <= 1'b0;
  temp[3] <= 1'b0;
end

There is also a nice Python module named wget that is pretty easy to use. Found here.

This demonstrates the simplicity of the design:

>>> import wget
>>> url = 'http://www.futurecrew.com/skaven/song_files/mp3/razorback.mp3'
>>> filename = wget.download(url)
100% [................................................] 3841532 / 3841532>
>> filename
'razorback.mp3'

Enjoy.

However, if wget doesn't work (I've had trouble with certain PDF files), try this solution.

Edit: You can also use the out parameter to use a custom output directory instead of current working directory.

>>> output_directory = <directory_name>
>>> filename = wget.download(url, out=output_directory)
>>> filename
'razorback.mp3'

add "--psm 7 -c tessedit_char_whitelist=0123456789'" works for me when the image contain's only 1 line.

Take out the "http://www.w3.org/TR/html4/loose.dtd" from the DOCTYPE declaration and it fix your problem.

Cheers! :)

I had exactly same problem (on OS X Maverics 10.9.1 with SQLite3 3.7.13, but I don't think SQLite is related to the cause). I tried to import csv data saved from MS Excel 2011, which btw. uses ';' as columns separator. I found out that csv file from Excel still uses newline character from Mac OS 9 times, changing it to unix newline solved the problem. AFAIR BBEdit has a command for this, as well as Sublime Text 2.

Another correct way to get selected value would be using this selector:

$("option[value="0"]:selected")

Best for you!

$var:25%;
$foo:5px;
.selector {
    height:unquote("calc( #{$var} - #{$foo} )");
}

As sjdh also mentioned, ggplot2 comes to the rescue. A more intuitive way without making a dummy data set is to use xlim:

library(ggplot2)
eq <- function(x){sin(x)}
base <- ggplot() + xlim(0, 30)
base + geom_function(fun=eq)

Additionally, for a smoother graph we can set the number of points over which the graph is interpolated using n:

base + geom_function(fun=eq, n=10000)

Try below code:

myArray = myArray.Where(s => (myArray.IndexOf(s) != indexValue)).ToArray();

or

myArray = myArray.Where(s => (s != "not_this")).ToArray();

 $('div#imageContainer').click(function () {
      $('div#imageContainerimg').attr('src', 'YOUR NEW IMAGE URL HERE'); 
});

If you want to convert from char to int, why not think about unicode number?

SELECT UNICODE(';') -- 59

This way you can convert any char to int without any error. Cheers.

you are calling the push() on an array element (int), where push() should be called on the array, also handling/filling the array this way makes no sense you can do it like this

for (var i = 0; i < rows - 1; i++)
{
  for (var j = c; j < cols; j++)
  {
    myArray[i].push(0);
  }
}


for (var i = r; i < rows - 1; i++)
{

  for (var j = 0; j < cols; j++)
  {
      col.push(0);
  }
}

you can also combine the two loops using an if condition, if row < r, else if row >= r

This should work :

<td>{{ number_format($Expense->price, 2) }}</td>

In more recent versions of SQL Server Management studio, you can now right click on a database and 'Take Database Offline'. This gives you the option to Drop All Active Connections to the database.

I got the same use case today(31/07/2018) and found this to be a workaround. It is based on my research and it worked for me. Expectation - To achieve the following in TypeScript:

var myStaticClass = {
    property: 10,
    method: function(){} 
}

I did this:

//MyStaticMembers.ts
namespace MyStaticMembers {
        class MyStaticClass {
           static property: number = 10;
           static myMethod() {...}
        }
        export function Property(): number {
           return MyStaticClass.property;
        }
        export function Method(): void {
           return MyStaticClass.myMethod();
        }
     }

Hence we shall consume it as below:

//app.ts
/// <reference path="MyStaticMembers.ts" />
    console.log(MyStaticMembers.Property);
    MyStaticMembers.Method();

This worked for me. If anyone has other better suggestions please let us all hear it !!! Thanks...

Ctrl + 7 to comment a selected text.

Building on verified answer, for me this worked best:

ab = pd.concat({k: pd.DataFrame(v).T for k, v in data.items()}, axis=0)
ab.T

Just create this class and add it to your element to be centered.

.navbar-center {
  margin-left: auto;
  margin-right: auto;
}

It means to group by the first column regardless of what it's called. You can do the same with ORDER BY.

Use:

Dim n As String = MsgBox("Do you really want to exit?", MsgBoxStyle.YesNo, "Confirmation Dialog Box")
If n = vbYes Then
    MsgBox("Current Form is closed....")
    Me.Close() 'Current Form Closed
    Yogi_Cottex.Show() 'Form Name.show()
End If

There are dictionary comprehensions in Python 2.7+, but they don't work quite the way you're trying. Like a list comprehension, they create a new dictionary; you can't use them to add keys to an existing dictionary. Also, you have to specify the keys and values, although of course you can specify a dummy value if you like.

>>> d = {n: n**2 for n in range(5)}
>>> print d
{0: 0, 1: 1, 2: 4, 3: 9, 4: 16}

If you want to set them all to True:

>>> d = {n: True for n in range(5)}
>>> print d
{0: True, 1: True, 2: True, 3: True, 4: True}

What you seem to be asking for is a way to set multiple keys at once on an existing dictionary. There's no direct shortcut for that. You can either loop like you already showed, or you could use a dictionary comprehension to create a new dict with the new values, and then do oldDict.update(newDict) to merge the new values into the old dict.

Embedded environment, sometime, there is no MMU, less memory, less storage space. In C programming level, almost same, cross compiler do their job.

I had an issue with Page.ClientScript.RegisterStartUpScript - I wasn't using an update panel, but the control was cached. This meant that I had to insert the script into a Literal (or could use a PlaceHolder) so when rendered from the cache the script is included.

A similar solution might work for you.

While working in a big project which has complex build system and where it is hard to get (or modify) the gcc/g++ command directly there is another way to see the result of macro expansion. Simply redefine the macro, and you will get output similiar to following:

file.h: note: this is the location of the previous definition
#define MACRO current_value

"[1-9][0-9]*|0"

I'd just use "[0-9]+" to represent positive whole numbers.

Phoronix did some benchmarks about this, but it is about a snapshot version of Clang/LLVM from a few months back. The results being that things were more-or-less a push; neither GCC nor Clang is definitively better in all cases.

Since you'd use the latest Clang, it's maybe a little less relevant. Then again, GCC 4.6 is slated to have some major optimizations for Core 2 and i7, apparently.

I figure Clang's faster compilation speed will be nicer for original developers, and then when you push the code out into the world, Linux distro/BSD/etc. end-users will use GCC for the faster binaries.

You do have an RTRIM and an LTRIM function. You can combine them to get the trim function you want.

UPDATE Table
SET Name = RTRIM(LTRIM(Name))

struct Node {
    let data: Int
    init(_ d:Int){
        data = d
    }
}

struct Stack {
    private var backingStore = [Node]()
    private var minArray = [Int]()

    mutating func push(n:Node) {
        backingStore.append(n)
        minArray.append(n.data)
        minArray.sort(>)
        minArray
    }

    mutating func pop() -> Node? {
        if(backingStore.isEmpty){
            return nil
        }

        let n = backingStore.removeLast()

        var found = false
        minArray = minArray.filter{
            if (!found && $0 == n.data) {
                found = true
                return false
            }
            return true
        }
        return n
    }

    func min() -> Int? {
        return minArray.last
    }
}

The above methods are useful but they are not full-proof because it will give error if time is between 12:00 AM/PM and 01:00 AM/PM . It will return the "No Go" in-spite of being in between the timing . Here is the code for the same:

$time = '2019-03-27 12:00 PM';

$date_one = $time; 
$date_one = strtotime($date_one);
$date_one = strtotime("+60 minutes", $date_one);
$date_one =  date('Y-m-d h:i A', $date_one);

$date_ten = strtotime($time); 
$date_ten = strtotime("-12 minutes", $date_ten); 
$date_ten = date('Y-m-d h:i A', $date_ten);

$paymentDate='2019-03-27 12:45 AM';

$contractDateBegin = date('Y-m-d h:i A', strtotime($date_ten)); 
$contractDateEnd = date('Y-m-d h:i A', strtotime($date_one));

echo $paymentDate; 
echo "---------------"; 
echo $contractDateBegin; 
echo "---------------"; 
echo $contractDateEnd; 
echo "---------------";

$contractDateEnd='2019-03-27 01:45 AM';

if($paymentDate > $contractDateBegin && $paymentDate < $contractDateEnd)  
{  
 echo "is between";
} 
else
{  
  echo "NO GO!";  
}

Here you will get output "NO Go" because 12:45 > 01:45.

To get proper output date in between, make sure that for "AM" values from 01:00 AM to 12:00 AM will get converted to the 24-hour format. This little trick helped me.

You can keep your initial linear layout by nesting the relative layout within the linear layout:

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView android:text="welcome" 
        android:id="@+id/TextView"

On the latest support library none of the solutions discussed here are necessary anymore. You can play with your Activity's fragments as you like using the FragmentTransaction. Just make sure that your fragments can be identified either with an id or tag.

The fragments will be restored automatically as long as you don't try to recreate them on every call to onCreate(). Instead, you should check if savedInstanceState is not null and find the old references to the created fragments in this case.

Here is an example:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState == null) {
        myFragment = MyFragment.newInstance();
        getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.my_container, myFragment, MY_FRAGMENT_TAG)
                .commit();
    } else {
        myFragment = (MyFragment) getSupportFragmentManager()
                .findFragmentByTag(MY_FRAGMENT_TAG);
    }
...
}

Note however that there is currently a bug when restoring the hidden state of a fragment. If you are hiding fragments in your activity, you will need to restore this state manually in this case.

This answer explains the theoretical limitation of why regular expressions are not the right tool for this task.

Regular expressions can not do this.

Regular expressions are based on a computing model known as Finite State Automata (FSA). As the name indicates, a FSA can remember only the current state, it has no information about the previous states.

In the above diagram, S1 and S2 are two states where S1 is the starting and final step. So if we try with the string 0110 , the transition goes as follows:

      0     1     1     0
-> S1 -> S2 -> S2 -> S2 ->S1

In the above steps, when we are at second S2 i.e. after parsing 01 of 0110, the FSA has no information about the previous 0 in 01 as it can only remember the current state and the next input symbol.

In the above problem, we need to know the no of opening parenthesis; this means it has to be stored at some place. But since FSAs can not do that, a regular expression can not be written.

However, an algorithm can be written to do this task. Algorithms are generally falls under Pushdown Automata (PDA). PDA is one level above of FSA. PDA has an additional stack to store some additional information. PDAs can be used to solve the above problem, because we can 'push' the opening parenthesis in the stack and 'pop' them once we encounter a closing parenthesis. If at the end, stack is empty, then opening parenthesis and closing parenthesis matches. Otherwise not.

I got this error when I modified an Nlog configuration file and didn't format the XML correctly.

Wouldn't something akin to this be better, security-wise?:

sqlplus -s /nolog << EOF
CONNECT admin/password;

whenever sqlerror exit sql.sqlcode;
set echo off 
set heading off

@pl_script_1.sql
@pl_script_2.sql

exit;
EOF 

If you use a Container as the body of the Scaffold, its size will be accordingly the size of its child, and usually that is not what you want when you try to add a background image to your app.

Looking at this other question, @collin-jackson was also suggesting to use Stack instead of Container as the body of the Scaffold and it definitely does what you want to achieve.

This is how my code looks like

@override
Widget build(BuildContext context) {
  return new Scaffold(
    body: new Stack(
      children: <Widget>[
        new Container(
          decoration: new BoxDecoration(
            image: new DecorationImage(image: new AssetImage("images/background.jpg"), fit: BoxFit.cover,),
          ),
        ),
        new Center(
          child: new Text("Hello background"),
        )
      ],
    )
  );
}

This will work, and if you need where statement you can add it as parameter.

class GenericDAOWithJPA<T, ID extends Serializable> {

.......

public List<T> findAll() {
            return entityManager.createQuery("Select t from " + persistentClass.getSimpleName() + " t").getResultList();
    }
}

Instead of checking for Build.VERSION.SDK_INT >= Build.VERSION_CODES.O as many answers suggest, there is a slightly simpler way -

Add the following line to the application section of AndroidManifest.xml file as explained in the Set Up a Firebase Cloud Messaging Client App on Android doc:

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id" 
        android:value="@string/default_notification_channel_id" />

Then add a line with a channel name to the values/strings.xml file:

<string name="default_notification_channel_id">default</string>

After that you will be able to use the new version of NotificationCompat.Builder constructor with 2 parameters (since the old constructor with 1 parameter has been deprecated in Android Oreo):

private void sendNotification(String title, String body) {
    Intent i = new Intent(this, MainActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pi = PendingIntent.getActivity(this,
            0 /* Request code */,
            i,
            PendingIntent.FLAG_ONE_SHOT);

    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, 
        getString(R.string.default_notification_channel_id))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(title)
            .setContentText(body)
            .setAutoCancel(true)
            .setSound(sound)
            .setContentIntent(pi);

    NotificationManager manager = 
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    manager.notify(0, builder.build());
}

In addition to the other answers, on a recent C library (Posix 2008 compliant), you could use getline. See this answer (to a related question).

You can solve the problem by downloading the 'conveyor' library from extensions and update in Visual Studio.

You can access it from other devices.

• Open Visual Studio

• Tools > Extensions and Updates

• Online > Visual Studio Marketplace

• Search 'Conveyor'
• Download and install this extension

When you launch the API, you can access it from other devices. This plugin creates a link from your own ip address.

Example: https://youripadress:5000/api/values

crypto now supports base64 (reference):

cipher.final('base64') 

So you could simply do:

var cipher = crypto.createCipheriv('des-ede3-cbc', encryption_key, iv);
var ciph = cipher.update(plaintext, 'utf8', 'base64');
ciph += cipher.final('base64');

var decipher = crypto.createDecipheriv('des-ede3-cbc', encryption_key, iv);
var txt = decipher.update(ciph, 'base64', 'utf8');
txt += decipher.final('utf8');

Your confusion stems from the fact that declared properties are not (necessarily named the same as) (instance) variables.

The expresion

indexPath.row

is equivalent to

[indexPath row]

and the assignment

delegate.myData = [myData objectAtIndex:indexPath.row];

is equivalent to

[delegate setMyData:[myData objectAtIndex:[indexPath row]]];

assuming standard naming for synthesised properties.

Furthermore, delegate is probably declared as being of type id<SomeProtocol>, i.e., the compiler hasn’t been able to provide actual type information for delegate at that point, and the debugger is relying on information provided at compile-time. Since id is a generic type, there’s no compile-time information about the instance variables in delegate.

Those are the reasons why you don’t see myData or row as variables.

If you want to inspect the result of sending -row or -myData, you can use commands p or po:

p (NSInteger)[indexPath row]
po [delegate myData]

or use the expressions window (for instance, if you know your delegate is of actual type MyClass *, you can add an expression (MyClass *)delegate, or right-click delegate, choose View Value as… and type the actual type of delegate (e.g. MyClass *).

That being said, I agree that the debugger could be more helpful:

• There could be an option to tell the debugger window to use run-time type information instead of compile-time information. It'd slow down the debugger, granted, but would provide useful information;

• Declared properties could be shown up in a group called properties and allow for (optional) inspection directly in the debugger window. This would also slow down the debugger because of the need to send a message/execute a method in order to get information, but would provide useful information, too.

To delete rows empty in table

syntax:

DELETE FROM table_name 
WHERE column_name IS NULL;

example:

Table name: data ---> column name: pkdno

DELETE FROM data 
WHERE pkdno IS NULL;

Answer: 5 rows deleted. (sayso)

1. Install Xcode and Xcode Command Line Tools as mentioned.
2. Use Pillow instead, as PIL is basically dead. Pillow is a maintained fork of PIL.

https://pypi.org/project/Pillow/

pip install Pillow

If you have both Pythons installed and want to install this for Python3:

python3 -m pip install Pillow

Set flags on Activity's Window as below

@Override public void onResume() {
 super.onResume();
 getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

@Override public void onPause() {
 super.onPause();
 getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

This works

var Box = React.createClass({
    getInitialState: function() {
        return {
            color: 'white'
        };
    },

    changeColor: function() {
        var newColor = this.state.color == 'white' ? 'black' : 'white';
        this.setState({ color: newColor });
    },

    render: function() {
        return (
            <div>
                <div
                    className='box'
                    style={{background:this.state.color}}
                    onClick={this.changeColor}
                >
                    In here already
                </div>
            </div>
        );
    }
});

ReactDOM.render(<Box />, document.getElementById('div1'));
ReactDOM.render(<Box />, document.getElementById('div2'));
ReactDOM.render(<Box />, document.getElementById('div3'));

and in your css, delete the styles you have and put this

.box {
  width: 200px;
  height: 200px;
  border: 1px solid black;
  float: left;
}

You have to style the actual div you are calling onClick on. Give the div a className and then style it. Also remember to remove this block where you are rendering App into the dom, App is not defined

ReactDOM.render(<App />,document.getElementById('root'));

Simply forcefully kill the process ID, the hadoop job will also be killed automatically . Use this command:

kill -9 <process_id> 

eg: process ID no: 4040 namenode

username@hostname:~$ kill -9 4040

Javascript files are often cached by the browser for a lot longer than you might expect.

This can often result in unexpected behaviour when you release a new version of your JS file.

Therefore, it is common practice to add a QueryString parameter to the URL for the javascript file. That way, the browser caches the Javascript file with v=1. When you release a new version of your javascript file you change the url's to v=2 and the browser will be forced to download a new copy.

Change the following line in your Eval.svc file from:

<%@ ServiceHost Language="C#" Debug="true" Service="EvalServiceLibary.Eval" %> 

to:

<%@ ServiceHost Language="C#" Debug="true" Service="EvalServiceLibary.EvalService" %>

As others have pointed out, ideally, the foreign key would be created as a reference to a primary key (usually an IDENTITY column). However, we don't live in an ideal world, and sometimes even a "small" change to a schema can have significant ripple effects to the application logic.

Consider the case of a Customer table with a SSN column (and a dumb primary key), and a Claim table that also contains a SSN column (populated by business logic from the Customer data, but no FK exists). The design is flawed, but has been in use for several years, and three different applications have been built on the schema. It should be obvious that ripping out Claim.SSN and putting in a real PK-FK relationship would be ideal, but would also be a significant overhaul. On the other hand, putting a UNIQUE constraint on Customer.SSN, and adding a FK on Claim.SSN, could provide referential integrity, with little or no impact on the applications.

Don't get me wrong, I'm all for normalization, but sometimes pragmatism wins over idealism. If a mediocre design can be helped with a band-aid, surgery might be avoided.

I'd wrap the dictionary in another class:

public class MyListDictionary
{

    private Dictionary<string, List<string>> internalDictionary = new Dictionary<string,List<string>>();

    public void Add(string key, string value)
    {
        if (this.internalDictionary.ContainsKey(key))
        {
            List<string> list = this.internalDictionary[key];
            if (list.Contains(value) == false)
            {
                list.Add(value);
            }
        }
        else
        {
            List<string> list = new List<string>();
            list.Add(value);
            this.internalDictionary.Add(key, list);
        }
    }

}

Eric Niebler is working on a range-proposal and some of the examples show how to remove certain elements. Removing 8. Does create a new vector.

#include <iostream>
#include <range/v3/all.hpp>

int main(int argc, char const *argv[])
{
    std::vector<int> vi{2,4,6,8,10};
    for (auto& i : vi) {
        std::cout << i << std::endl;
    }
    std::cout << "-----" << std::endl;
    std::vector<int> vim = vi | ranges::view::remove_if([](int i){return i == 8;});
    for (auto& i : vim) {
        std::cout << i << std::endl;
    }
    return 0;
}

outputs

2
4
6
8
10
-----
2

The accepted answer will return all the parent nodes too. To get only the actual nodes with ABC even if the string is after
:

//*[text()[contains(.,'ABC')]]/text()[contains(.,"ABC")]

I want to stress on using

SET XACT_ABORT ON;

for the MSSQL transaction with multiple sql statements.

See: https://msdn.microsoft.com/en-us/library/ms188792.aspx They provide a very good example.

So, the final code should look like the following:

SET XACT_ABORT ON;

BEGIN TRANSACTION
   DECLARE @DataID int;
   INSERT INTO DataTable (Column1 ...) VALUES (....);
   SELECT @DataID = scope_identity();
   INSERT INTO LinkTable VALUES (@ObjectID, @DataID);
COMMIT

For performing Unmarshall using JAXB:

1) Convert given XML to XSD(by yourself or by online convertor),

2) Create a JAXB project in eclipse,

3) Create XSD file and paste that converted XSD content in it,

4) Right click on **XSD file--> Generate--> JAXB Classes-->follow the instructions(this will create all nessasary .java files in src, i.e., one package-info, object factory and pojo class),

5) Create another .java file in src to operate unmarshall operation, and run it.

Happy Coding !!

Well, the shortest way I know of, is following:

psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}

database_name: Which database should you insert your file data in.

file_path: Absolute path to the file through which you want to perform the importing.

host_name: The name of the host. For development purposes, it is mostly localhost.

Upon entering this command in console, you will be prompted to enter your password.

This is what it worked for me. The tsconfig.json has an option noImplicitAny that it was set to true, I just simply set it to false and now I can access properties in objects using strings.

$(function(){
    var _top = $(window).scrollTop();
    var _direction;
    $(window).scroll(function(){
        var _cur_top = $(window).scrollTop();
        if(_top < _cur_top)
        {
            _direction = 'down';
        }
        else
        {
            _direction = 'up';
        }
        _top = _cur_top;
        console.log(_direction);
    });
});

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

All the three syntax work very well.

Another way is to first write

path = r'C:\user\...................' (whatever is the path for you)

and then passing it to os.chdir(path)

In the above query when we are trying to combine two or more tables it is necessary to use joins and specify the alias name for description and date (that means, the table from which you are fetching the description and date values)

SELECT DISTINCT Description, Date as treatmentDate  
FROM doothey.Patient P  
INNER JOIN doothey.Account A ON P.PatientID = A.PatientID  
INNER JOIN doothey.AccountLine AL ON A.AccountNo = AL.AccountNo  
INNER JOIN doothey.Item I ON AL.ItemNo = I.ItemNo  
WHERE p.FamilyName = 'Stange' AND p.GivenName = 'Jessie';

"0,1".split(',')

If you want to do it via javascript rather than CSS you can use:

var link = document.getElementById('nav-ask');
link.style.display = 'none'; //or
link.style.visibility = 'hidden';

depending on what you want to do.
