If one need to use the sp_executesql with OUTPUT variables:

EXEC sp_executesql @sql
                  ,N'@p0 INT'
                  ,N'@p1 INT OUTPUT'
                  ,N'@p2 VARCHAR(12) OUTPUT' 
                  ,@p0
                  ,@p1 OUTPUT
                  ,@p2 OUTPUT;

This is called string interpolation; it doesn't exist as such in Java.

One approach is to use String.format:

String string = String.format("A string %s", aVariable);

Another approach is to use a templating library such as Velocity or FreeMarker.

In addition to the answers above, you can check the type of object using type(plt.subplots()) which returns a tuple, on the other hand, type(plt.subplot()) returns matplotlib.axes._subplots.AxesSubplot which you can't unpack.

Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:

$(boot2docker shellinit)

I had tested these commands:

>>  docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory
>>  boot2docker shellinit
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/ca.pem
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/cert.pem
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/key.pem
    export DOCKER_HOST=tcp://192.168.59.103:2376

    export DOCKER_TLS_VERIFY=1
>> docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory

Notice that docker info returned that same error. however.. when using $(boot2docker shellinit)...

Make sure that in the path to the project there is no foldername having whitespace. While creating a project the specified path folders must not contain any space in their naming.

I ran into the same problem and Master Morality's answer didn't do it for me. The following, which is based on the previous answer, worked:

private void run_cmd(string cmd, string args)
{
 ProcessStartInfo start = new ProcessStartInfo();
 start.FileName = cmd;//cmd is full path to python.exe
 start.Arguments = args;//args is path to .py file and any cmd line args
 start.UseShellExecute = false;
 start.RedirectStandardOutput = true;
 using(Process process = Process.Start(start))
 {
     using(StreamReader reader = process.StandardOutput)
     {
         string result = reader.ReadToEnd();
         Console.Write(result);
     }
 }
}

As an example, cmd would be @C:/Python26/python.exe and args would be C://Python26//test.py 100 if you wanted to execute test.py with cmd line argument 100. Note that the path the .py file does not have the @ symbol.

Like this: HttpRequest.UrlReferrer Property

Uri myReferrer = Request.UrlReferrer;
string actual = myReferrer.ToString();

Simply check the var/lib/cloud/instance symlink, it should point to /var/lib/cloud/instances/{instance-id} where {instance_id} is your instance-id.

You can use a RegularExpression validator. The ValidationExpression property has a button you can press in Visual Studio's property's panel that gets lists a lot of useful expressions. The one they use for email addresses is:

\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

There are multiple ways to achieve this

1. Slash concatenation

  var MultiLine=  '1\
    2\
    3\
    4\
    5\
    6\
    7\
    8\
    9';

2. regular concatenation

var MultiLine = '1'
+'2'
+'3'
+'4'
+'5';

3. Array Join concatenation

var MultiLine = [
'1',
'2',
'3',
'4',
'5'
].join('');

Performance wise, Slash concatenation (first one) is the fastest.

Refer this test case for more details regarding the performance

Update:

With the ES2015, we can take advantage of its Template strings feature. With it, we just need to use back-ticks for creating multi line strings

Example:

 `<h1>{{title}}</h1>
  <h2>{{hero.name}} details!</h2>
  <div><label>id: </label>{{hero.id}}</div>
  <div><label>name: </label>{{hero.name}}</div>
  `

You can use pandas dataframes or series as Julien said but if you want to restrict your-self to numpy you can pass an additional array of indices:

from sklearn.model_selection import train_test_split
import numpy as np
n_samples, n_features, n_classes = 10, 2, 2
data = np.random.randn(n_samples, n_features)  # 10 training examples
labels = np.random.randint(n_classes, size=n_samples)  # 10 labels
indices = np.arange(n_samples)
x1, x2, y1, y2, idx1, idx2 = train_test_split(
    data, labels, indices, test_size=0.2)

use this

<div id="date">23/05/2013</div>
<script type="text/javascript">
$(document).ready(function(){
  var x = $("#date").text();
    x.text(x.substring(0, 2) + '<br />'+x.substring(3));     
});
</script>

I found a simple solution.

Just change the cell focus after click on cell.

private void DGV_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex == "Here checkbox column id or name") {
        DGV.Item(e.ColumnIndex, e.RowIndex + 1).Selected = true;
        //Here your code

    }
}

Don't forget to check if the column of your (ckeckbox + 1) index exist.

Since the assembly resides in a temporary cache, you should combine the path to get the dll's config:

var appConfig = ConfigurationManager.OpenExeConfiguration(
    Path.Combine(Environment.CurrentDirectory, Assembly.GetExecutingAssembly().ManifestModule.Name));

For those wondering, @edward-coast

If you want to set the keep alive for the server, add this to /etc/ssh/sshd_config:

ClientAliveInterval 60
ClientAliveCountMax 2

ClientAliveInterval: Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client.

ClientAliveCountMax: Sets the number of client alive messages (see below) which may be sent without sshd(8) receiving any messages back from the client. If this threshold is reached while client alive messages are being sent, sshd will disconnect the client, terminating the session.

Unpack it and place somewhere you can find it. In my example, I will assume you will place it to C:\Selenium\iexploredriver.exe

Then you have to set it up in the system. Here is the Java code pasted from my Selenium project:

File file = new File("C:/Selenium/iexploredriver.exe");
System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();

Basically, you have to set this property before you initialize driver

Reference:

• Driver executable must be set by the webdriver.ie.driver system property

Something like:

if(divisor == 0) {
  throw new ArithmeticException("Division by zero!");
}

SELECT * 
FROM table_name
WHERE table_name.the_date > DATE_SUB(CURDATE(), INTERVAL 1 DAY)

It is technically approved that MD5 is faster than SHA256 so in just verifying file integrity it will be sufficient and better for performance.

You are able to checkout the following resources:

• Speed Comparison of Popular Crypto Algorithms
• Comparison of cryptographic hash functions

This works better, as you can show validationMessage for a specified key:

    ModelState.AddModelError("keyName","Message");

and display it like this:

    @Html.ValidationMessage("keyName")

Using the LOAD DATA INFILE SQL statement you can import the CSV file, but you can't update data. However, there is a trick you can use.

• Create another temporary table to use for the import

• Load onto this table from the CSC

  LOAD DATA LOCAL INFILE '/file.csv'
  INTO TABLE temp_table
  FIELDS TERMINATED BY ','
  LINES TERMINATED BY '\n'
  (field1, field2, field3); 
  

• UPDATE the real table joining the table

  UPDATE maintable
  INNER JOIN temp_table A USING (field1)
  SET maintable.field1 = temp_table.field1
  

The best source for rationale for a Python addition would be its PEP: PEP 389: argparse - New Command Line Parsing Module, in particular, the section entitled, Why aren't getopt and optparse enough?

<span> elements are inline elements, as such layout properties such as width or margin don't work. You can fix that by either changing the <span> to a block element (such as <div>), or by using padding instead.

Note that making a span element a block element by adding display: block; is redundant, as a span is by definition a otherwise style-less inline element whereas div is an otherwise style-less block element. So the correct solution is to use a div instead of a block-span.

Maybe the span element is hidden. If that's the case then use the innerHtml property:

By.css:

String kk = wd.findElement(By.cssSelector("#customSelect_3 span.selectLabel"))
              .getAttribute("innerHTML");

By.xpath:

String kk = wd.findElement(By.xpath(
                   "//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel')]"))
              .getAttribute("innerHTML");

"/.//" means "look under the selected element".

You can wrap the whole connection in a context manager, like the following:

from contextlib import contextmanager
import pyodbc
import sys

@contextmanager
def open_db_connection(connection_string, commit=False):
    connection = pyodbc.connect(connection_string)
    cursor = connection.cursor()
    try:
        yield cursor
    except pyodbc.DatabaseError as err:
        error, = err.args
        sys.stderr.write(error.message)
        cursor.execute("ROLLBACK")
        raise err
    else:
        if commit:
            cursor.execute("COMMIT")
        else:
            cursor.execute("ROLLBACK")
    finally:
        connection.close()

Then do something like this where ever you need a database connection:

with open_db_connection("...") as cursor:
    # Your code here

The connection will close when you leave the with block. This will also rollback the transaction if an exception occurs or if you didn't open the block using with open_db_connection("...", commit=True).

I used this command to find last 5 minutes logs for particular event "DHCPACK", try below:

$ grep "DHCPACK" /var/log/messages | grep "$(date +%h\ %d) [$(date --date='5 min ago' %H)-$(date +%H)]:*:*"

You can download the Apache Standard Taglib and include the jar in your project.

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

• Overview of the New C++ (C++11/14) (PDF only) (Scott Meyers) (updated for C++14) These are the presentation materials (slides and some lecture notes) of a three-day training course offered by Scott Meyers, who's a highly respected author on C++. Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• The C++ Super-FAQ (Marshall Cline, Bjarne Stroustrup and others) is an effort by the Standard C++ Foundation to unify the C++ FAQs previously maintained individually by Marshall Cline and Bjarne Stroustrup and also incorporating new contributions. The items mostly address issues at an intermediate level and are often written with a humorous tone. Not all items might be fully up to date with the latest edition of the C++ standard yet.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

Why not create a webfont with your svg image or images, import the webfont in the css and then just change the color of the glyph using the css color attribute? No javascript needed

scanf needs to know the size of the data being pointed at by &d to fill it properly, whereas variadic functions promote floats to doubles (not entirely sure why), so printf is always getting a double.

So the methods mentioned above didn't work for me. What worked for me was googling Samsung Galaxy Tab USB driver and downloading and running the application that got my device recognized when I did adb devices. Since I was using a Samsung Galaxy, I used this link to download the usb driver from the OFFICIAL Samsung site. You would want to google your own respective android model usb driver

http://www.samsung.com/us/support/owners/product/SCH-I925EAAVZW

After downloading it, I ran the application to install my usb driver and then did adb devices. Make sure your Google USB driver from the Android SDK is downloaded and that your sdk is up to date as well. Also, make sure that your USB debugging mode is enable by going to Settings -> Developer Options -> then checking USB debugging. After all this, your device in the Device Manager should not have a yellow exclamation point next to it. When you run adb devices your device should show up. Hope this helps people. I literally spent hours trying to figure this out. Hopefully my answer could save you guys the hours I spent googling.

Some general constructor tips:

• Try to focus all initialization in a single constructor and call it from the other constructors
  • This works well if multiple constructors exist to simulate default parameters
• Never call a non-final method from a constructor
  • Private methods are final by definition
  • Polymorphism can kill you here; you can end up calling a subclass implementation before the subclass has been initialized
  • If you need "helper" methods, be sure to make them private or final
• Be explicit in your calls to super()
  • You would be surprised at how many Java programmers don't realize that super() is called even if you don't explicitly write it (assuming you don't have a call to this(...) )

• Know the order of initialization rules for constructors. It's basically:

  1. this(...) if present (just move to another constructor)
  2. call super(...) [if not explicit, call super() implicitly]
  3. (construct superclass using these rules recursively)
  4. initialize fields via their declarations
  5. run body of current constructor
  6. return to previous constructors (if you had encountered this(...) calls)

The overall flow ends up being:

• move all the way up the superclass hierarchy to Object
• while not done
  • init fields
  • run constructor bodies
  • drop down to subclass

For a nice example of evil, try figuring out what the following will print, then run it

package com.javadude.sample;

/** THIS IS REALLY EVIL CODE! BEWARE!!! */
class A {
    private int x = 10;
    public A() {
        init();
    }
    protected void init() {
        x = 20;
    }
    public int getX() {
        return x;
    }
}

class B extends A {
    private int y = 42;
    protected void init() {
        y = getX();
    }
    public int getY() {
        return y;
    }
}

public class Test {
    public static void main(String[] args) {
        B b = new B();
        System.out.println("x=" + b.getX());
        System.out.println("y=" + b.getY());
    }
}

I'll add comments describing why the above works as it does... Some of it may be obvious; some is not...

Just add style="table-layout: fixed ; width: 100%;" inside <table> tag and also if you do not specify any styles and add just style=" width: 100%;" inside <table> You will be able to resolve it.

I'm using psr-4 autoloading specification.

Had to add below lines to the project's composer.json. I intend to place my class files inside src/App , src/Test and library directory.

"autoload": {
        "psr-4": {
            "OrgName\\AppType\\AppName\\": ["src/App", "src/Test", "library/"]
        }
    } 

This is pretty much self explaining. OrgName\AppType\AppName is my intended namespace prefix. e.g for class User in src/App/Controller/Provider/User.php -

namespace OrgName\AppType\AppName\Controller\Provider; // namespace declaration

use OrgName\AppType\AppName\Controller\Provider\User; // when using the class

Also notice "src/App", "src/Test" .. are from your web-root that is where your composer.json is. Nothing to do with the vendor dir. take a look at vendor/autoload.php

Now if composer is installed properly all that is required is #composer update

After composer update my classes loaded successfully. What I observed is that composer is adding a line in vendor/composer/autoload_psr4.php

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(
    'Monolog\\' => array($vendorDir . '/monolog/monolog/src/Monolog'),
    'OrgName\\AppType\\AppName\\' => array($baseDir . '/src/App', $baseDir . '/src/Test', $baseDir . '/library'),
);

This is how composer maps. For psr-0 mapping is in vendor/composer/autoload_classmap.php

Jackson and Gson are the most complete Java JSON packages regarding actual data binding support; many other packages only provide primitive Map/List (or equivalent tree model) binding. Both have complete support for generic types, as well, as enough configurability for many common use cases.

Since I am more familiar with Jackson, here are some aspects where I think Jackson has more complete support than Gson (apologies if I miss a Gson feature):

• Extensive annotation support; including full inheritance, and advanced "mix-in" annotations (associate annotations with a class for cases where you can not directly add them)
• Streaming (incremental) reading, writing, for ultra-high performance (or memory-limited) use cases; can mix with data binding (bind sub-trees) -- EDIT: latest versions of Gson also include streaming reader
• Tree model (DOM-like access); can convert between various models (tree <-> java object <-> stream)
• Can use any constructors (or static factory methods), not just default constructor
• Field and getter/setter access (earlier gson versions only used fields, this may have changed)
• Out-of-box JAX-RS support
• Interoperability: can also use JAXB annotations, has support/work-arounds for common packages (joda, ibatis, cglib), JVM languages (groovy, clojure, scala)
• Ability to force static (declared) type handling for output
• Support for deserializing polymorphic types (Jackson 1.5) -- can serialize AND deserialize things like List correctly (with additional type information)
• Integrated support for binary content (base64 to/from JSON Strings)

for simple tasks, we can use http://flower.readthedocs.io/en/latest/screenshots.html and http://policystat.github.io/jobtastic/ to do the monitoring.

and for complicated tasks, say a task which deals with a lot other modules. We recommend manually record the progress and message on the specific task unit.

Better way is to autowire with a constructor:

private final HttpServletRequest httpServletRequest;

public ClassConstructor(HttpServletRequest httpServletRequest){
      this.httpServletRequest = httpServletRequest;
}

SELECT e.*,
       cnt.colCount 
FROM eventsTable e
INNER JOIN (
           select columnName,count(columnName) as colCount
           from eventsTable e2 
          group by columnName
           ) as cnt on cnt.columnName = e.columnName
WHERE e.columnName='Business'

-- Added space

r+ is the canonical mode for reading and writing at the same time. This is not different from using the fopen() system call since file() / open() is just a tiny wrapper around this operating system call.

Change charset to from 'utf8mb4' to 'utf8' and

collation to 'utf8mb4_unicode_ci' to 'utf8_unicode_ci'

in config/database.php file

It worked for me.

Turning off my VPN resolved the issue.

How I work to automate Office / Excel:

1. Record a macro, this will generate a VBA template
2. Edit the VBA template so it will match my needs
3. Convert to VB.Net (A small step for men)
4. Leave it in VB.Net, Much more easy as doing it using C#

rsync include exclude pattern examples:

"*"         means everything
"dir1"      transfers empty directory [dir1]
"dir*"      transfers empty directories like: "dir1", "dir2", "dir3", etc...
"file*"     transfers files whose names start with [file]
"dir**"     transfers every path that starts with [dir] like "dir1/file.txt", "dir2/bar/ffaa.html", etc...
"dir***"    same as above
"dir1/*"    does nothing
"dir1/**"   does nothing
"dir1/***"  transfers [dir1] directory and all its contents like "dir1/file.txt", "dir1/fooo.sh", "dir1/fold/baar.py", etc...

And final note is that simply dont rely on asterisks that are used in the beginning for evaluating paths; like "**dir" (its ok to use them for single folders or files but not paths) and note that more than two asterisks dont work for file names.

The problem is not that you can't forward-declare a template class. Yes, you do need to know all of the template parameters and their defaults to be able to forward-declare it correctly:

namespace std {
  template<class T, class Allocator = std::allocator<T>>
  class list;
}

But to make even such a forward declaration in namespace std is explicitly prohibited by the standard: the only thing you're allowed to put in std is a template specialisation, commonly std::less on a user-defined type. Someone else can cite the relevant text if necessary.

Just #include <list> and don't worry about it.

Oh, incidentally, any name containing double-underscores is reserved for use by the implementation, so you should use something like TEST_H instead of __TEST__. It's not going to generate a warning or an error, but if your program has a clash with an implementation-defined identifier, then it's not guaranteed to compile or run correctly: it's ill-formed. Also prohibited are names beginning with an underscore followed by a capital letter, among others. In general, don't start things with underscores unless you know what magic you're dealing with.

I cloned the repository with HTTPS URL instead of SSH URL hence even after adding the SSH Key it was asking me for password on Bash Shell.

I just edited the ./.git/config file and changed the value of url variable by simply replacing the https:// to ssh://

E.g.

[core]
        ...
        ...
        ...
[remote "origin"]
        url = https://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

Changed to:

[core]
        ...
        ...
        ...
[remote "origin"]
        url = ssh://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

Note: There is no magic to animating a gif: it is either an animated gif or it is not. If the gif is not visible, very likely the path to the gif is wrong - or, as in your case, the container (div/p/etc) is not large enough to display it. In your code sample, you did not specify height or width and that appeared to be problem.

If the gif is displayed but not animating, see reference links at very bottom of this answer.

Displaying the gif + overlay, however, is easier than you might think.

All you need are two absolute-position DIVs: an overlay div, and a div that contains your loading gif. Both have higher z-index than your page content, and the image has a higher z-index than the overlay - so they will display above the page when visible.

So, when the button is pressed, just unhide those two divs. That's it!

Once upon a midnight dreary, while I pondered weak and weary, over many a quaint and curious routine of forgotten code... While I nodded, nearly napping, suddenly there came a tapping... as of someone gently rapping - rapping at my office door. 'Tis the team leader, I muttered, tapping at my office door - only this and nothing more. Ah, distinctly I remember it was in the bleak December and each separate React print-out lay there crumpled on the floor. Eagerly I wished the morrow; vainly I had sought to borrow from Stack-O surcease from sorrow - sorrow for my routine's core. For the brilliant but unworking code my angels seem to just ignore. I'll be tweaking code... forevermore! - <a href="http://www.online-literature.com/poe/335/" target="_blank">Apologies To Poe</a></div>_x000D_

You might enjoy playing with the new backdrop-filter:blur(_px) css property that gives a blur effect to the underlying content, as used in above demo... (As of April 2020: works in Chrome, Edge, Safari, Android, but not yet in Firefox)

This way you check if the string is not null and not empty, also considering the empty spaces:

boolean isEmpty = str == null || str.trim().length() == 0;
if (isEmpty) {
    // handle the validation
}

Try this:

if (MessageBox.Show("Are you sure", "Title_here", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
{
    Do something here for 'Yes'...
}

When it comes to using a very long number that may exceed 32 bits to represent, you may use long to make sure that you'll not have strange behavior.

From Java 5 you can use in-boxing and out-boxing features to make the use of int and Integer completely the same. It means that you can do :

int myInt = new Integer(11);
Integer myInt2 = myInt;

The in and out boxing allow you to switch between int and Integer without any additional conversion (same for Long,Double,Short too)

You may use int all the time, but Integer contains some helper methods that can help you to do some complex operations with integers (such as Integer.parseInt(String) )

You can solve this problem by following two ways:
A) Start your WAMP befor you login to skype. So that WAMP will take over the the port and there will be no conflict with the port number. And you are able to use Skype as well as WAMP.
But this is not the permanent solution for your problem. Whenever you want to start WAMP you need to signout Skype first and than only you are able to start WAMP. Which is really i don’t like.

B) Second option is to change the port of Skype itself, so that it will not conflict with WAMP. Following screen/steps will help you to solve this problem:
1) SignIn to Skype.
2) Got to the Tools -> options
3) Select the “Advanced” -> Connection
4) Unchecked “Use port 80 and 443 as alternatives for incoming connections” checkbox and click save.
5) Now Signout and SignIn again to skype. (this change will take affect only you relogin to skype)
Now every time you start WAMP will not conflict with skype.

Using plain javascript:

element.parentNode

In jQuery:

element.parent()

you can easily implement by jQuery

$('input').attr('autocomplete','off');

in javascript return statement only used inside function block. if you try to use return statement inside independent if else block it trigger syntax error : Illegal return statement in JavaScript

Here is my example code to avoid such error :

<script type = 'text/javascript'>
(function(){
    var ss= 'no';
    if(getStatus(ss)){
        alert('Status return true');   
    }else{
        alert('Status return false'); 
    }

    function getStatus(ask){
        if(ask=='yes')
        {
        return true;     
        }
        else
        {
        return false;
        }
    }
})();
</script>

Please check Jsfiddle example

onBindViewHolder() is called for each and every item and setting the click listener inside onBindVieHolder() is an unnecessary option to repeat when you can call it once in your ViewHolder constructor.

public class MyViewHolder extends RecyclerView.ViewHolder 
      implements View.OnClickListener{
   public final TextView textView; 

   public MyViewHolder(View view){
      textView = (TextView) view.findViewById(R.id.text_view);
      view.setOnClickListener(this);
      // getAdapterPosition() retrieves the position here.
   } 

   @Override
   public void onClick(View v){
      // Clicked on item 
      Toast.makeText(mContext, "Clicked on position: " + getAdapterPosition(), Toast.LENGTH_SHORT).show();
   }
}

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

You should set a condition loop to check the TextBox1 value.

If TextBox1.value = "" then
   MsgBox "The file not exist" 
   Exit sub 'exit the macro
End If

Hope it help you.

Note that to call First here is actually to call a Linq extension of IEnumerable, which is implemented by Dictionary<TKey,TValue>. But for a Dictionary, "first" doesn't have a defined meaning. According to this answer, the last item added ends up being the "First" (in other words, it behaves like a Stack), but that is implementation specific, it's not the guaranteed behavior. In other words, to assume you're going to get any defined item by calling First would be to beg for trouble -- using it should be treated as akin to getting a random item from the Dictionary, as noted by Bobson below. However, sometimes this is useful, as you just need any item from the Dictionary.

Just use the Linq First():

var first = like.First();
string key = first.Key;
Dictionary<string,string> val = first.Value;

Note that using First on a dictionary gives you a KeyValuePair, in this case KeyValuePair<string, Dictionary<string,string>>.

Note also that you could derive a specific meaning from the use of First by combining it with the Linq OrderBy:

var first = like.OrderBy(kvp => kvp.Key).First();

How about SymPy? Their solver looks like what you need. Have a look at their source code if you want to build the library yourself…

You don't have to use Calendar. You can just play with timestamps :

Date d = initDate();//intialize your date to any date 
Date dateBefore = new Date(d.getTime() - n * 24 * 3600 * 1000 l ); //Subtract n days   

UPDATE DO NOT FORGET TO ADD "l" for long by the end of 1000.

Please consider the below WARNING:

Adding 1000*60*60*24 milliseconds to a java date will once in a great while add zero days or two days to the original date in the circumstances of leap seconds, daylight savings time and the like. If you need to be 100% certain only one day is added, this solution is not the one to use.

Use the re library

import re
myString = "I want to Remove all white \t spaces, new lines \n and tabs \t"
myString = re.sub(r"[\n\t\s]*", "", myString)
print myString

Output:

IwanttoRemoveallwhitespaces,newlinesandtabs

You probably need to wrap the UNION in a sub-SELECT and apply the WHERE clause afterward:

SELECT * FROM (
    SELECT * FROM Table1 WHERE Field1 = Value1
    UNION
    SELECT * FROM Table2 WHERE Field1 = Value2
) AS t WHERE Field2 = Value3

Basically, the UNION is looking for two complete SELECT statements to combine, and the WHERE clause is part of the SELECT statement.

It may make more sense to apply the outer WHERE clause to both of the inner queries. You'll probably want to benchmark the performance of both approaches and see which works better for you.

My solution was to create a pipelined function. The advantages are that the query can be a single line:

• select * from table(yourfunction(param1, param2));
• You can join your results to other tables or filter or sort them as you please..
• the results appear as regular query results so you can easily manipulate them.

To define the function you would need to do something like the following:

  -- Declare the record columns
  TYPE your_record IS RECORD(
     my_col1 VARCHAR2(50), 
     my_col2 varchar2(4000)
  );
  TYPE your_results IS TABLE OF your_record;

  -- Declare the function
  function yourfunction(a_Param1 varchar2, a_Param2 varchar2)
  return your_results pipelined is
    rt          your_results;
  begin
    -- Your query to load the table type
    select s.col1,s.col2
    bulk collect into rt
    from your_table s
    where lower(s.col1) like lower('%'||a_Param1||'%');

    -- Stuff the results into the pipeline..
    if rt.count > 0 then 
      for i in rt.FIRST .. rt.LAST loop 
        pipe row (rt(i)); 
      end loop; 
    end if;

    -- Add more results as you please....
    return;
  end find;

And as mentioned above, all you would do to view your results is:

select * from table(yourfunction(param1, param2)) t order by t.my_col1;

My issue was also within the heredoc. I had it within an if/then statement and the closing bracket directly after the semicolon. So I moved the closing bracket to its own line and issue was fixed.

I changed:

... ;}

to:

... ;
}

There's a much better way to achieve your desired result, using SQL Server's analytic (or windowing) functions.

SELECT DISTINCT Date, MAX(Score) OVER(PARTITION BY Date) FROM ScoresTable

If you need more than just the date and max score combinations, you can use ranking functions, eg:

SELECT  *
FROM    ScoresTable t
JOIN (   
    SELECT 
        ScoreId,
        ROW_NUMBER() OVER (PARTITION BY Date ORDER BY Score DESC) AS [Rank] 
        FROM ScoresTable
) window ON window.ScoreId = p.ScoreId AND window.[Rank] = 1

You may want to use RANK() instead of ROW_NUMBER() if you want multiple records to be returned if they both share the same MAX(Score).

Add your multiple columns with comma separations:

UPDATE settings SET postsPerPage = $postsPerPage, style= $style WHERE id = '1'

However, you're not sanitizing your inputs?? This would mean any random hacker could destroy your database. See this question: What's the best method for sanitizing user input with PHP?

Also, is style a number or a string? I'm assuming a string, so it would need to be quoted.

Assuming you have a form like this:

<form id="myForm" action="foo.php" method="post">
   <input type="text" value="" />
   <input type="submit" value="submit form" />

</form>

You can attach a onsubmit-event with jQuery like this:

$('#myForm').submit(function() {
  alert('Handler for .submit() called.');
  return false;
});

If you return false the form won't be submitted after the function, if you return true or nothing it will submit as usual.

See the jQuery documentation for more info.

If it's conciseness you're after, you might like:

prop.table(table(tips$smoker))

and then scale by 100 and round if you like. Or more like your exact output:

tbl <- table(tips$smoker)
cbind(tbl,prop.table(tbl))

If you wanted to do this for multiple columns, there are lots of different directions you could go depending on what your tastes tell you is clean looking output, but here's one option:

tblFun <- function(x){
    tbl <- table(x)
    res <- cbind(tbl,round(prop.table(tbl)*100,2))
    colnames(res) <- c('Count','Percentage')
    res
}

do.call(rbind,lapply(tips[3:6],tblFun))
       Count Percentage
Female    87      35.66
Male     157      64.34
No       151      61.89
Yes       93      38.11
Fri       19       7.79
Sat       87      35.66
Sun       76      31.15
Thur      62      25.41
Dinner   176      72.13
Lunch     68      27.87

If you don't like stack the different tables on top of each other, you can ditch the do.call and leave them in a list.

I know this is old, but it is actually very possible.

There's one IDE that is missing in this list and which is very efficient (I've used it in many C/C++ projects without any issues): Netbeans.

If you have SSH access, you don't need to SSH first and then copy, just use Secure Copy (SCP) from the destination.

scp user@host:/path/file /localpath/file

Wild card characters are supported, so

scp user@host:/path/folder/* /localpath/folder

will copy all of the remote files in that folder.If copying more then one directory.

note -r will copy all sub-folders and content too.

There's sooo many ways to continue a line in powershell, with pipes, brackets, parentheses, operators, dots, even with a comma. Here's a blog about it: https://get-powershellblog.blogspot.com/2017/07/bye-bye-backtick-natural-line.html

You can continue right after statements like foreach and if as well.

I believe VS2010 to be right this time, and I'd check if I had the standard handy, but currently I don't.

Now, it's exactly like the error message says: You can't capture stuff outside of the enclosing scope of the lambda.^† grid is not in the enclosing scope, but this is (every access to grid actually happens as this->grid in member functions). For your usecase, capturing this works, since you'll use it right away and you don't want to copy the grid

auto lambda = [this](){ std::cout << grid[0][0] << "\n"; }

If however, you want to store the grid and copy it for later access, where your puzzle object might already be destroyed, you'll need to make an intermediate, local copy:

vector<vector<int> > tmp(grid);
auto lambda = [tmp](){}; // capture the local copy per copy

† I'm simplifying - Google for "reaching scope" or see §5.1.2 for all the gory details.

Update: Remote Debugging

Previously, console logging was the best option for debugging JavaScript on Android. These days with Chrome for Android remote debugging, we are able to make use of all the goodness of the Chrome for Desktop Developer Tools on Android. Check out https://developers.google.com/chrome-developer-tools/docs/remote-debugging for more information.

Update: JavaScript Console

You can also navigate to about:debug in the URL bar to activate the debug menu and the JavaScript error console with recent Android devices. You should see SHOW JAVASCRIPT CONSOLE at the top of the Browser.

Currently in Android 4.0.3 (Ice Cream Sandwich), the logcat outputs to the browser channel. So you can filter using adb logcat browser:* *:S.

Original Answer

You can use the built in console JavaScript object to print log messages that you can review with adb logcat.

console.error('1');
console.info('2');
console.log('3');
console.warn('4')

Produces this output:

D/WebCore (  165): Console: 1 line: 0 source: http://...
D/WebCore (  165): Console: 2 line: 0 source: http://...
D/WebCore (  165): Console: 3 line: 0 source: http://...
D/WebCore (  165): Console: 4 line: 0 source: http://...

Determining the version of WebKit

If you type javascript:alert(navigator.userAgent) in the location bar you’ll see the WebKit version listed e.g.

In Chrome: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.2 (KHTML, like Gecko) Chrome/4.0.221.6 Safari/532.2

On Android Emulator Mozilla/5.0 (Linux; U; Android 1.6; en-us; sdk Build/DRC76) AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/525.20.1

N.B.

Versions of WebKit that are not part of a Safari release have a + after the version number, and their version number is generally higher than the latest released version of WebKit. So, for example, 528+ is an unofficial build of WebKit that is newer than the 525.x version that shipped as part of Safari 3.1.2.

It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:

var canvas = document.createElement('canvas');
canvas.id     = "CursorLayer";
canvas.width  = 1224;
canvas.height = 768;
canvas.style.zIndex   = 8;
canvas.style.position = "absolute";
canvas.style.border   = "1px solid";
window.onload = function() {
    document.getElementById("CursorLayer");
}

MS SQL Studio take care of when you delete the column but if you need to Delete Constraint Programmatically here is simple solution

Here’s a code snippet that’ll drop a column with a default constraint:

DECLARE @ConstraintName nvarchar(200)
SELECT @ConstraintName = Name FROM SYS.DEFAULT_CONSTRAINTS WHERE PARENT_OBJECT_ID = OBJECT_ID('__TableName__') AND PARENT_COLUMN_ID = (SELECT column_id FROM sys.columns WHERE NAME = N'__ColumnName__' AND object_id = OBJECT_ID(N'__TableName__'))
IF @ConstraintName IS NOT NULL
EXEC('ALTER TABLE __TableName__ DROP CONSTRAINT ' + @ConstraintName)
IF EXISTS (SELECT * FROM syscolumns WHERE id=object_id('__TableName__') AND name='__ColumnName__')
EXEC('ALTER TABLE __TableName__ DROP COLUMN __ColumnName__')

Just replace TableName and ColumnName with the appropriate values. You can safely run this even if the column has already been dropped.

Bonus: Here’s the code to drop foreign keys and other types of constraints.

IF EXISTS(SELECT 1 FROM INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE where TABLE_NAME = '__TableName__' AND COLUMN_NAME = '__ColumnName__')
BEGIN
SELECT @ConstraintName = CONSTRAINT_NAME FROM INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE where TABLE_NAME = '__TableName__' AND COLUMN_NAME = '__ColumnName__'
EXEC('ALTER TABLE __TableName__ DROP CONSTRAINT ' + @ConstraintName)
END

There are quite a few elements of the $.Ajax() that can cause issues if they are not defined correctly. I would suggest rewritting your javascript in its most basic form, you will most likely find that it works fine.

Script example:

$.ajax({
    type: "POST",
    url: '/Default.aspx/TestMethod',
    data: '{message: "HAI" }',
    contentType: "application/json; charset=utf-8",
    success: function (data) {
        console.log(data);
    },
    failure: function (response) {
        alert(response.d);
    }
});

WebMethod example:

[WebMethod]
public static string TestMethod(string message)
{
     return "The message" + message;
}

You can also try <C-x><C-l> which will repeat the last line from insert mode and brings you a completion window with all of the lines. It works almost like <C-p>

Since I think you are new with Python, lets do the long way, iterate thru your list using for loop and multiply and append each element to a new list.

using for loop

lst = [5, 20 ,15]
product = []
for i in lst:
    product.append(i*5)
print product

using list comprehension, this is also same as using for-loop but more 'pythonic'

lst = [5, 20 ,15]

prod = [i * 5 for i in lst]
print prod

I was able to handle that by simply overriding the method 'unsuccessfulAuthentication' in my filter. There, I send an error response to the client with the desired HTTP status code.

@Override
protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response,
        AuthenticationException failed) throws IOException, ServletException {

    if (failed.getCause() instanceof RecordNotFoundException) {
        response.sendError((HttpServletResponse.SC_NOT_FOUND), failed.getMessage());
    }
}

Answering the question in your title, you can query sys.tables or sys.objects where type = 'U' to check for the existence of a table. You can also use OBJECT_ID('table_name', 'U'). If it returns a non-null value then the table exists:

IF (OBJECT_ID('dbo.My_Table', 'U') IS NULL)
BEGIN
    CREATE TABLE dbo.My_Table (...)
END

You can do the same for databases with DB_ID():

IF (DB_ID('My_Database') IS NULL)
BEGIN
    CREATE DATABASE My_Database
END

If you want to create the database and then start using it, that needs to be done in separate batches. I don't know the specifics of your case, but there shouldn't be many cases where this isn't possible. In a SQL script you can use GO statements. In an application it's easy enough to send across a new command after the database is created.

The only place that you might have an issue is if you were trying to do this in a stored procedure and creating databases on the fly like that is usually a bad idea.

If you really need to do this in one batch, you can get around the issue by using EXEC to get around the parsing error of the database not existing:

CREATE DATABASE Test_DB2

IF (OBJECT_ID('Test_DB2.dbo.My_Table', 'U') IS NULL)
BEGIN
    EXEC('CREATE TABLE Test_DB2.dbo.My_Table (my_id INT)')
END

EDIT: As others have suggested, the INFORMATION_SCHEMA.TABLES system view is probably preferable since it is supposedly a standard going forward and possibly between RDBMSs.

Check whether you had applied any filters in the console. It happens to me in chrome console.

If you don't mind modifying your HTML a little to include the value attribute of the options, you can significantly reduce the code necessary to do this:

<option>B</option>

to

<option value="B">B</option>

This will be helpful when you want to do something like:

<option value="IL">Illinois</option>

With that, the follow jQuery will make the change:

$("select option[value='B']").attr("selected","selected");

If you decide not to include the use of the value attribute, you will be required to cycle through each option, and manually check its value:

$("select option").each(function(){
  if ($(this).text() == "B")
    $(this).attr("selected","selected");
});

Use Simple HTML

<frameset cols="25%,*">
  <frame src="frame_a.htm">
  <frame src="frame_b.htm">
</frameset>

I thought I'd share what works for me in MVC5 for anyone that comes looking for a similar answer.

My Controller Signature looks like this:

public ActionResult Index(DateTime? EventDate, DateTime? EventTime)
{

}

My ActionLink looks like this in Razor:

@Url.Action("Index", "Book", new { EventDate = apptTime, EventTime = apptTime})

This gives a URL like this:

Book?EventDate=01%2F20%2F2016%2014%3A15%3A00&EventTime=01%2F20%2F2016%2014%3A15%3A00

Which encodes the date and time as it should.

Change the code to

List<string> nameslist = new List<string> {"one", "two", "three"};

or

List<string> nameslist = new List<string>(new[] {"one", "two", "three"});

The [Flags] attribute should be used whenever the enumerable represents a collection of possible values, rather than a single value. Such collections are often used with bitwise operators, for example:

var allowedColors = MyColor.Red | MyColor.Green | MyColor.Blue;

Note that the [Flags] attribute doesn't enable this by itself - all it does is allow a nice representation by the .ToString() method:

enum Suits { Spades = 1, Clubs = 2, Diamonds = 4, Hearts = 8 }
[Flags] enum SuitsFlags { Spades = 1, Clubs = 2, Diamonds = 4, Hearts = 8 }

...

var str1 = (Suits.Spades | Suits.Diamonds).ToString();
           // "5"
var str2 = (SuitsFlags.Spades | SuitsFlags.Diamonds).ToString();
           // "Spades, Diamonds"

It is also important to note that [Flags] does not automatically make the enum values powers of two. If you omit the numeric values, the enum will not work as one might expect in bitwise operations, because by default the values start with 0 and increment.

Incorrect declaration:

[Flags]
public enum MyColors
{
    Yellow,  // 0
    Green,   // 1
    Red,     // 2
    Blue     // 3
}

The values, if declared this way, will be Yellow = 0, Green = 1, Red = 2, Blue = 3. This will render it useless as flags.

Here's an example of a correct declaration:

[Flags]
public enum MyColors
{
    Yellow = 1,
    Green = 2,
    Red = 4,
    Blue = 8
}

To retrieve the distinct values in your property, one can do this:

if (myProperties.AllowedColors.HasFlag(MyColor.Yellow))
{
    // Yellow is allowed...
}

or prior to .NET 4:

if((myProperties.AllowedColors & MyColor.Yellow) == MyColor.Yellow)
{
    // Yellow is allowed...
}

if((myProperties.AllowedColors & MyColor.Green) == MyColor.Green)
{
    // Green is allowed...
}    

Under the covers

This works because you used powers of two in your enumeration. Under the covers, your enumeration values look like this in binary ones and zeros:

 Yellow: 00000001
 Green:  00000010
 Red:    00000100
 Blue:   00001000

Similarly, after you've set your property AllowedColors to Red, Green and Blue using the binary bitwise OR | operator, AllowedColors looks like this:

myProperties.AllowedColors: 00001110

So when you retrieve the value you are actually performing bitwise AND & on the values:

myProperties.AllowedColors: 00001110
             MyColor.Green: 00000010
             -----------------------
                            00000010 // Hey, this is the same as MyColor.Green!

The None = 0 value

And regarding the use of 0 in your enumeration, quoting from MSDN:

[Flags]
public enum MyColors
{
    None = 0,
    ....
}

Use None as the name of the flag enumerated constant whose value is zero. You cannot use the None enumerated constant in a bitwise AND operation to test for a flag because the result is always zero. However, you can perform a logical, not a bitwise, comparison between the numeric value and the None enumerated constant to determine whether any bits in the numeric value are set.

You can find more info about the flags attribute and its usage at msdn and designing flags at msdn

In this code i is iterated till 3 then the loop ends;

int function (void)
{
    for (int i=0; i<5; i++)
    {
      if (i == 3)
      {
         break;
      }
    }
}

In this code i is iterated till 3 but with an output;

There are Python libraries that can recognize files based on their content (usually a header / magic number) and that don't rely on the file name or extension.

If you're addressing many different file types, you can use python-magic. That's just a Python binding for the well-established magic library. This has a good reputation and (small endorsement) in the limited use I've made of it, it has been solid.

There are also libraries for more specialized file types. For example, the Python standard library has the imghdr module that does the same thing just for image file types.

If you need dependency-free (pure Python) file type checking, see filetype.

I found that the above answer caused me an exception when I tried to instantiate the parser. I found the following code that resolved this at http://docstore.mik.ua/orelly/xml/sax2/ch03_02.htm.

import org.xml.sax.*;
import javax.xml.parsers.*;

XMLReader        parser;

try {
    SAXParserFactory factory;

    factory = SAXParserFactory.newInstance ();
    factory.setNamespaceAware (true);
    parser = factory.newSAXParser ().getXMLReader ();
    // success!

} catch (FactoryConfigurationError err) {
    System.err.println ("can't create JAXP SAXParserFactory, "
    + err.getMessage ());
} catch (ParserConfigurationException err) {
    System.err.println ("can't create XMLReader with namespaces, "
    + err.getMessage ());
} catch (SAXException err) {
    System.err.println ("Hmm, SAXException, " + err.getMessage ());
}

In my case I had this referenceError as the order of script calls was wrong. Solved that by changing the order:

<script src="js/index.js"></script>

to

<script src="js/jquery-1.10.2.js"></script>
<script src="js/index.js"></script>

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

If I may I could give you some new code for the same task, in my code you can create a so called 'document'(not really)and it is saved, and can be opened up again. It is also stored as a string file though(not a document). Here is the code:

#include "iostream"

#include "windows.h"

#include "string"

#include "fstream"

using namespace std;

int main() {

string saveload;


cout << "---------------------------" << endl;
cout << "|enter 'text' to write your document    |" << endl;
cout << "|enter 'open file' to open the document |" << endl;
cout << "----------------------------------------" << endl;
while (true){
    getline(cin, saveload);

    if (saveload == "open file"){
        string filenamet;
        cout << "file name? " << endl;
        getline(cin, filenamet, '*');
        ifstream loadFile;

        loadFile.open(filenamet, ifstream::in);

        cout << "the text you entered was: ";

        while (loadFile.good()){

            cout << (char)loadFile.get();

            Sleep(100);
        }

        cout << "" << endl;

        loadFile.close();

    }

    if (saveload == "text") {
        string filename;
        cout << "file name: " << endl;
        getline(cin, filename,'*');
        string textToSave;
        cout << "Enter your text: " << endl;
        getline(cin, textToSave,'*');

        ofstream saveFile(filename);

        saveFile << textToSave;

        saveFile.close();

    }
}
return 0;
}

Just take this code and change it to serve your purpose. DREAM BIG,THINK BIG, DO BIG

Since I cannot comment, adding this note in addition to @jethro answer.

I found out that you also need to do the FOREIGN KEY line as the last part of create the table statement, otherwise you will get a syntax error when installing your app. What I mean is, you cannot do something like this:

private static final String TASK_TABLE_CREATE = "create table "
    + TASK_TABLE + " (" + TASK_ID
    + " integer primary key autoincrement, " + TASK_TITLE
    + " text not null, " + TASK_NOTES + " text not null, "
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+" ("+CAT_ID+"), "
+ TASK_DATE_TIME + " text not null);";

Where I put the TASK_DATE_TIME after the foreign key line.

There is more than one way to define "memory leak". In particular, there are two primary definitions of "memory leak" that are in common usage among programmers.

The first commonly used definition of "memory leak" is, "Memory was allocated and was not subsequently freed before the program terminated." However, many programmers (rightly) argue that certain types of memory leaks that fit this definition don't actually pose any sort of problem, and therefore should not be considered true "memory leaks".

An arguably stricter (and more useful) definition of "memory leak" is, "Memory was allocated and cannot be subsequently freed because the program no longer has any pointers to the allocated memory block." In other words, you cannot free memory that you no longer have any pointers to. Such memory is therefore a "memory leak". Valgrind uses this stricter definition of the term "memory leak". This is the type of leak which can potentially cause significant heap depletion, especially for long lived processes.

The "still reachable" category within Valgrind's leak report refers to allocations that fit only the first definition of "memory leak". These blocks were not freed, but they could have been freed (if the programmer had wanted to) because the program still was keeping track of pointers to those memory blocks.

In general, there is no need to worry about "still reachable" blocks. They don't pose the sort of problem that true memory leaks can cause. For instance, there is normally no potential for heap exhaustion from "still reachable" blocks. This is because these blocks are usually one-time allocations, references to which are kept throughout the duration of the process's lifetime. While you could go through and ensure that your program frees all allocated memory, there is usually no practical benefit from doing so since the operating system will reclaim all of the process's memory after the process terminates, anyway. Contrast this with true memory leaks which, if left unfixed, could cause a process to run out of memory if left running long enough, or will simply cause a process to consume far more memory than is necessary.

Probably the only time it is useful to ensure that all allocations have matching "frees" is if your leak detection tools cannot tell which blocks are "still reachable" (but Valgrind can do this) or if your operating system doesn't reclaim all of a terminating process's memory (all platforms which Valgrind has been ported to do this).

I have joined the answer from Lucas and "ASP.NET MVC Helpers, Merging two object htmlAttributes together" and plus controllerName to following code:

// Sample usage in CSHTML

 @Html.ActionImage("Edit",
       "EditController"
        new { id = MyId },
       "~/Content/Images/Image.bmp",
       new { width=108, height=129, alt="Edit" })

And the extension class for the code above:

using System.Collections.Generic;
using System.Reflection;
using System.Web.Mvc;

namespace MVC.Extensions
{
    public static class MvcHtmlStringExt
    {
        // Extension method
        public static MvcHtmlString ActionImage(
          this HtmlHelper html,
          string action,
          string controllerName,
          object routeValues,
          string imagePath,
          object htmlAttributes)
        {
            //https://stackoverflow.com/questions/4896439/action-image-mvc3-razor
            var url = new UrlHelper(html.ViewContext.RequestContext);

            // build the <img> tag
            var imgBuilder = new TagBuilder("img");
            imgBuilder.MergeAttribute("src", url.Content(imagePath));

            var dictAttributes = htmlAttributes.ToDictionary();

            if (dictAttributes != null)
            {
                foreach (var attribute in dictAttributes)
                {
                    imgBuilder.MergeAttribute(attribute.Key, attribute.Value.ToString(), true);
                }
            }                        

            string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);

            // build the <a> tag
            var anchorBuilder = new TagBuilder("a");
            anchorBuilder.MergeAttribute("href", url.Action(action, controllerName, routeValues));
            anchorBuilder.InnerHtml = imgHtml; // include the <img> tag inside            
            string anchorHtml = anchorBuilder.ToString(TagRenderMode.Normal);

            return MvcHtmlString.Create(anchorHtml);
        }

        public static IDictionary<string, object> ToDictionary(this object data)
        {
            //https://stackoverflow.com/questions/6038255/asp-net-mvc-helpers-merging-two-object-htmlattributes-together

            if (data == null) return null; // Or throw an ArgumentNullException if you want

            BindingFlags publicAttributes = BindingFlags.Public | BindingFlags.Instance;
            Dictionary<string, object> dictionary = new Dictionary<string, object>();

            foreach (PropertyInfo property in
                     data.GetType().GetProperties(publicAttributes))
            {
                if (property.CanRead)
                {
                    dictionary.Add(property.Name, property.GetValue(data, null));
                }
            }
            return dictionary;
        }
    }
}

Use IList to get the JArray Count and Use Loop to Convert into List

       var array = result["items"].Value<JArray>();

        IList collection = (IList)array;

        var list = new List<string>();

        for (int i = 0; i < collection.Count; j++)
            {
              list.Add(collection[i].ToString());             
            }                         

seeing as autocomplete=off is deprecated, I suggest a more recent solution.

Set your password field to a normal text field, and mask your input with "discs" using CSS. the code should look like this:

<input type="text" class="myPassword" /> 

input .myPassword{
    text-security:disc;
    -webkit-text-security:disc;
    -mox-text-security:disc;
}

Please note that this may not work propely on firefox browsers, and an additional walkaround is needed. Read more about it here :https://stackoverflow.com/a/49304708/5477548.

The solution was taken from this link, but to comply with SO "no-hotlinks" i summarized it here.

This might be your script-free solution: http://davidwalsh.name/css-transform-rotate

It's supported in all browsers prefixed and, in IE10-11 and all still-used Firefox versions, unprefixed.

That means that if you don't care for old IEs (the bane of web designers) you can skip the -ms- and -moz- prefixes to economize space.

However, the Webkit browsers (Chrome, Safari, most mobile navigators) still need -webkit-, and there's a still-big cult following of pre-Next Opera and using -o- is sensate.

if (android.os.Build.VERSION.SDK_INT >= 21) {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position], context.getTheme()));
} else {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position]));
}

For brevity, we can understand these two APIs like below:

1. X.class.isAssignableFrom(Y.class)

If X and Y are the same class, or X is Y's super class or super interface, return true, otherwise, false.

2. X.class.isInstance(y)

Say y is an instance of class Y, if X and Y are the same class, or X is Y's super class or super interface, return true, otherwise, false.

Without over-complicating the problem, to grant the EXECUTE on chosen database:

USE [DB]
GRANT EXEC TO [User_Name];

As @thomas-lotze has mentioned, currently pip tooling does not do that as there is no corresponding --user option. But what I find is that I can check in ~/.local/bin and look for the specific pip#.# which looks to me like it corresponds to the --user option.

In my case:

antho@noctil: ~/.l/bin$ pwd
/home/antho/.local/bin
antho@noctil: ~/.l/bin$ ls pip*
pip  pip2  pip2.7  pip3  pip3.5

And then just uninstall with the specific pip version.

This probably does not answer your question, but I had the same question and it answered mine.

I changed Private Function to Public Function and it worked.

CMake is actually pretty good for this. The key part was everyone on the Windows side has to remember to run CMake before loading in the solution, and everyone on our Mac side would have to remember to run it before make.

The hardest part was as a Windows developer making sure your structural changes were in the cmakelist.txt file and not in the solution or project files as those changes would probably get lost and even if not lost would not get transferred over to the Mac side who also needed them, and the Mac guys would need to remember not to modify the make file for the same reasons.

It just requires a little thought and patience, but there will be mistakes at first. But if you are using continuous integration on both sides then these will get shook out early, and people will eventually get in the habit.

Here is an article with live working demo Class Animation In JQuery

You can try this,

$(function () {
   $("#btnSubmit").click(function () {
   $("#btnClass").removeClass("btnDiv").addClass("btn");
   });
});

you can also use switchClass() method - it allows you to animate the transition of adding and removing classes at the same time.

$(function () {
        $("#btnSubmit").click(function () {
            $("#btnClass").switchClass("btn", "btnReset", 1000, "easeInOutQuad");
        });
    });

This is NOT possible

The Simulator does not run ARM code, ONLY x86 code. Unless you have the raw source code from Apple, you won't see the App Store on the Simulator.

The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account. To test your app on an actual device, you will need to be apart of the Apple Developer program.

Under some circumstances (if you get "ERROR 1064 (42000): You have an error in your SQL syntax;...") you need to do

ALTER TABLE mytable MODIFY mytable.mycolumn varchar(255);

While sourceSets allows you to include entire directory structures, there's no way to exclude parts of it in Android Studio (as of version 1.2), as described here: Android Studio Exclude Class from build?

Until Android Studio gets updated to support include/exclude directives for Android sources, Symlinks work quite well. If you're using Windows, native tools such as junction or mklink can accomplish the equivalent of Un*x symlinks. CygWin can also create these with a little coersion. See: Git Symlinks in Windows and How to make symbolic link with cygwin in Windows 7

This was very helpful. Angular doesn't work exactly like JQuery. It has its own jsonp() method, which indeed requires "&callback=JSON_CALLBACK" at the end of the query string. Here's an example:

var librivoxSearch = angular.module('librivoxSearch', []);
librivoxSearch.controller('librivoxSearchController', function ($scope, $http) {
    $http.jsonp('http://librivox.org/api/feed/audiobooks/author/Melville?format=jsonp&callback=JSON_CALLBACK').success(function (data) {
        $scope.data = data;
    });
});

Then display or manipulate {{ data }} in your Angular template.

For me to work I had to explicitly provide the type although it is contained in the blob by doing so:

const file = new File([blob], 'untitled', { type: blob.type })

@Simple-Solution

I use a simple Python HTTP server. When in the directory of the Angular app in question (using a MBP with Mavericks 10.9 and Python 2.x) I simply run

python -m SimpleHTTPServer 8080

And that sets up the simple server on port 8080 letting you visit localhost:8080 on your browser to view the app in development.

Hope that helped!

OK guys the truth is somewhere in the middle cause you have to see the issue from the parent's view and child's. The solution below works ONLY when spinner mode = dialog regardless of Android version (no problem there.. tested it in VD and DesireS with Android =>2.2) :

1. .Set you spinner's(the parent) mode like :

   android:spinnerMode="dialog"  
   

2. Set the textview's(child custom view) properties to :

   android:layout_weight="1"  
   android:ellipsize="none"  
   android:maxLines="100"  
   android:scrollHorizontally="false"
   

I hope this works for you also.

If you have lists that are not the same length, you may not want to use zip as per Patricks answer. This works:

>>> zip(*[('a', 1), ('b', 2), ('c', 3), ('d', 4)])
[('a', 'b', 'c', 'd'), (1, 2, 3, 4)]

But with different length lists, zip truncates each item to the length of the shortest list:

>>> zip(*[('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', )])
[('a', 'b', 'c', 'd', 'e')]

You can use map with no function to fill empty results with None:

>>> map(None, *[('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', )])
[('a', 'b', 'c', 'd', 'e'), (1, 2, 3, 4, None)]

zip() is marginally faster though.

Try this -

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

Alternatively,

1. you could also declare in your manifest file's activity -

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Main"
          android:label="@string/app_name"
          android:windowSoftInputMode="stateHidden"
          >

2. If you have already been using android:windowSoftInputMode for a value like adjustResize or adjustPan, you can combine two values like:

<activity
        ...
        android:windowSoftInputMode="stateHidden|adjustPan"
        ...
        >

This will hide the keyboard whenever appropriate but pan the activity view in case the keyboard has to be shown.

Style the ::-ms-clear pseudo-element for the box:

.someinput::-ms-clear {
    display: none;
}

As an exploration of this topic, I have a presentation titled "Securing TodoMVC Using the Web Cryptography API" (video, code).

It uses the Web Cryptography API to store the todo list encrypted in localStorage by password protecting the application and using a password derived key for encryption. If you forget or lose the password, there is no recovery. (Disclaimer - it was a POC and not intended for production use.)

As the other answers state, this is still susceptible to XSS or malware installed on the client computer. However, any sensitive data would also be in memory when the data is stored on the server and the application is in use. I suggest that offline support may be the compelling use case.

In the end, encrypting localStorage probably only protects the data from attackers that have read only access to the system or its backups. It adds a small amount of defense in depth for OWASP Top 10 item A6-Sensitive Data Exposure, and allows you to answer "Is any of this data stored in clear text long term?" correctly.

One simple way can be the use of assign() function that is pre-defined in vector class.

e.g.

array[5]={1,2,3,4,5};

vector<int> v;
v.assign(array, array+5); // 5 is size of array.

Updated for Numpy 1.7.0:(Hat-tip to @Rolf Bartstra.)

a=np.empty(n); a.fill(5) is fastest.

In descending speed order:

%timeit a=np.empty(1e4); a.fill(5)
100000 loops, best of 3: 5.85 us per loop

%timeit a=np.empty(1e4); a[:]=5 
100000 loops, best of 3: 7.15 us per loop

%timeit a=np.ones(1e4)*5
10000 loops, best of 3: 22.9 us per loop

%timeit a=np.repeat(5,(1e4))
10000 loops, best of 3: 81.7 us per loop

%timeit a=np.tile(5,[1e4])
10000 loops, best of 3: 82.9 us per loop

Once you have selected the highest value, which is "12" in my example, you can then declare it as integer and increment your value:

$FileList = "1", "2", "11"
$foldername = [int]$FileList[2] + 1
$foldername

Since the Fetch API is supported by Chrome (and most other browsers), it is now quite easy to make HTTP requests from the devtools console.

To GET a JSON file for instance:

fetch('https://jsonplaceholder.typicode.com/posts/1')_x000D_
  .then(res => res.json())_x000D_
  .then(console.log)

Or to POST a new resource:

fetch('https://jsonplaceholder.typicode.com/posts', {_x000D_
  method: 'POST',_x000D_
  body: JSON.stringify({_x000D_
    title: 'foo',_x000D_
    body: 'bar',_x000D_
    userId: 1_x000D_
  }),_x000D_
  headers: {_x000D_
    'Content-type': 'application/json; charset=UTF-8'_x000D_
  }_x000D_
})_x000D_
.then(res => res.json())_x000D_
.then(console.log)

Chrome Devtools actually also support new async/await syntax (even though await normally only can be used within an async function):

const response = await fetch('https://jsonplaceholder.typicode.com/posts/1')
console.log(await response.json())

Notice that your requests will be subject to the same-origin policy, just like any other HTTP-request in the browser, so either avoid cross-origin requests, or make sure the server sets CORS-headers that allow your request.

Using a plugin (old answer)

As an addition to previously posted suggestions I've found the Postman plugin for Chrome to work very well. It allow you to set headers and URL parameters, use HTTP authentication, save request you execute frequently and so on.

I usually insert a blockquote and add a Unicode character(memo which is(U+1F4DD)) inside it.

...

Emoji

Of course, if you do not like you can search you like. I am sure there will be one in it is your satisfaction!

• find more emoji: https://emojipedia.org/

  just search you like icon and copy-paste then done(since it is a character, so it suitable for every device)

• find Code

  If you don't like copy paste and want to type yourself, you can consider searching the Unicode.

  

p.s. You can also pay attention to the emoji version (usually it is the same as the Unicode version), and more icons may appear in the future to your satisfaction.

• Unicode Version 14.0
• Emoji Version 14.0

You may get some information viewing it in assembly, but I think the easiest thing to do is fire up a virtual machine and see what it does. Make sure you have no open shares or anything like that that it can jump through though ;)

I know this post is older, but haven't seen a solution that provides the actual information, so I want to share what I use for SQL Server 2012 and above. the link below leads to the screenshot showing the information.

First (so no time is wasted):

SQL Server 2000:
SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')

SQL Server 2005+

The "SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')" is not in use anymore. You can see more details on MSFT documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/serverproperty-transact-sql?view=sql-server-2017

SQL Server 2005 - 2008R2 you would have to:

Using PowerShell: https://www.ryadel.com/en/sql-server-retrieve-product-key-from-an-existing-installation/

Using TSQL (you would need to know the registry key path off hand): https://docs.microsoft.com/en-us/sql/relational-databases/system-dynamic-management-views/sys-dm-server-registry-transact-sql?view=sql-server-2017

SQL Server 2012+

Now, you can extract SQL Server Licensing information from the SQL Server Error Log, granted it may not be formatted the way you want, but the information is there and can be parsed, along with more descriptive information that you probably didn't expect.

EXEC sp_readerrorlog @p1 = 0
                    ,@p2 = 1
                    ,@p3 = N'licensing'

NOTE: I tried pasting the image directly, but since I am new at stakoverflow we have to follow the link below.

SQL Server License information via sp_readerrorlog

Using css zebra styling

Copy paste this example and see the header fixed.

       <style>
       .zebra tr:nth-child(odd){
       background:white;
       color:black;
       }

       .zebra tr:nth-child(even){
       background: grey;
       color:black;
       }

      .zebra tr:nth-child(1) {
       background:black;
       color:yellow;
       position: fixed;
       margin:-30px 0px 0px 0px;
       }
       </style>


   <DIV  id= "stripped_div"

         class= "zebra"
         style = "
            border:solid 1px red;
            height:15px;
            width:200px;
            overflow-x:none;
            overflow-y:scroll;
            padding:30px 0px 0px 0px;"
            >

                <table>
                   <tr >
                       <td>Name:</td>
                       <td>Age:</td>
                   </tr>
                    <tr >
                       <td>Peter</td>
                       <td>10</td>
                   </tr>
                </table>

    </DIV>

Notice the top padding of of 30px in the div leaves space that is utilized by the 1st row of stripped data ie tr:nth-child(1) that is "fixed position" and formatted to a margin of -30px

Another approach is to (ab)use the PostgreSQL GUC mechanism to create variables. See this prior answer for details and examples.

You declare the GUC in postgresql.conf, then change its value at runtime with SET commands and get its value with current_setting(...).

I don't recommend this for general use, but it could be useful in narrow cases like the one mentioned in the linked question, where the poster wanted a way to provide the application-level username to triggers and functions.

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

Data types

• std::variant<Ts...>

  • Almost-always non-empty last I checked?
  • Tagged union type
  • {awesome|useful}

• std::optional

  • Maybe holds one of something
  • Ridiculously useful

• std::any

  • Holds one of anything (that is copyable)

• std::string_view

  • std::string like reference-to-character-array or substring
  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

File System TS v1

• [class.path]

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

It seems to me that the answers here are outdated. For me under Windows 10 and Git 2.15.0 this did the job:

git credential reject
protocol=https
host=github.com
<Empty line here>

And then to set the new username & password:

git credential fill
protocol=https
host=github.com
<empty line here>

After this, if the credentials now work on the desired target host, we should use git credential approve -as mentioned in typical use of Git credentials (step 4)- to tell the credential helpers to mark the credentials as approved and reuse them in future connections.

Conaider this situation:

Mark and Lisa are secretly a couple, and because of age difference they are not allowed to be together. Mark and Lisa meet every night when nobody is watching. They have estabilished their own set of rules how to comunicate when the time comes. He stands in her garden and throws the small rock at her window. Lisa knows that it is time, and responds by waving from the window and opening it afterwards so Mark can climb in. That was example how the API works. The rock is initial request to another end. Another end waves, opens the window which basicaly means "Welcome in!".

API is almost like human language but for computers.

use typescript for your coding, because it's object oriented, strictly typed and easy to maintain the code ...

Here one simple example I have created to share data between two controller using Typescript...

module Demo {
//create only one module for single Applicaiton
angular.module('app', []);
//Create a searvie to share the data
export class CommonService {
    sharedData: any;
    constructor() {
        this.sharedData = "send this data to Controller";
    }
}
//add Service to module app
angular.module('app').service('CommonService', CommonService);

//Create One controller for one purpose
export class FirstController {
    dataInCtrl1: any;
    //Don't forget to inject service to access data from service
    static $inject = ['CommonService']
    constructor(private commonService: CommonService) { }
    public getDataFromService() {
        this.dataInCtrl1 = this.commonService.sharedData;
    }
}
//add controller to module app
angular.module('app').controller('FirstController', FirstController);
export class SecondController {
    dataInCtrl2: any;
    static $inject = ['CommonService']
    constructor(private commonService: CommonService) { }
    public getDataFromService() {
        this.dataInCtrl2 = this.commonService.sharedData;
    }
}
angular.module('app').controller('SecondController', SecondController);

}

I think the main difference I can describe relates to record oriented vs. column oriented formats. Record oriented formats are what we're all used to -- text files, delimited formats like CSV, TSV. AVRO is slightly cooler than those because it can change schema over time, e.g. adding or removing columns from a record. Other tricks of various formats (especially including compression) involve whether a format can be split -- that is, can you read a block of records from anywhere in the dataset and still know it's schema? But here's more detail on columnar formats like Parquet.

Parquet, and other columnar formats handle a common Hadoop situation very efficiently. It is common to have tables (datasets) having many more columns than you would expect in a well-designed relational database -- a hundred or two hundred columns is not unusual. This is so because we often use Hadoop as a place to denormalize data from relational formats -- yes, you get lots of repeated values and many tables all flattened into a single one. But it becomes much easier to query since all the joins are worked out. There are other advantages such as retaining state-in-time data. So anyway it's common to have a boatload of columns in a table.

Let's say there are 132 columns, and some of them are really long text fields, each different column one following the other and use up maybe 10K per record.

While querying these tables is easy with SQL standpoint, it's common that you'll want to get some range of records based on only a few of those hundred-plus columns. For example, you might want all of the records in February and March for customers with sales > $500.

To do this in a row format the query would need to scan every record of the dataset. Read the first row, parse the record into fields (columns) and get the date and sales columns, include it in your result if it satisfies the condition. Repeat. If you have 10 years (120 months) of history, you're reading every single record just to find 2 of those months. Of course this is a great opportunity to use a partition on year and month, but even so, you're reading and parsing 10K of each record/row for those two months just to find whether the customer's sales are > $500.

In a columnar format, each column (field) of a record is stored with others of its kind, spread all over many different blocks on the disk -- columns for year together, columns for month together, columns for customer employee handbook (or other long text), and all the others that make those records so huge all in their own separate place on the disk, and of course columns for sales together. Well heck, date and months are numbers, and so are sales -- they are just a few bytes. Wouldn't it be great if we only had to read a few bytes for each record to determine which records matched our query? Columnar storage to the rescue!

Even without partitions, scanning the small fields needed to satisfy our query is super-fast -- they are all in order by record, and all the same size, so the disk seeks over much less data checking for included records. No need to read through that employee handbook and other long text fields -- just ignore them. So, by grouping columns with each other, instead of rows, you can almost always scan less data. Win!

But wait, it gets better. If your query only needed to know those values and a few more (let's say 10 of the 132 columns) and didn't care about that employee handbook column, once it had picked the right records to return, it would now only have to go back to the 10 columns it needed to render the results, ignoring the other 122 of the 132 in our dataset. Again, we skip a lot of reading.

(Note: for this reason, columnar formats are a lousy choice when doing straight transformations, for example, if you're joining all of two tables into one big(ger) result set that you're saving as a new table, the sources are going to get scanned completely anyway, so there's not a lot of benefit in read performance, and because columnar formats need to remember more about the where stuff is, they use more memory than a similar row format).

One more benefit of columnar: data is spread around. To get a single record, you can have 132 workers each read (and write) data from/to 132 different places on 132 blocks of data. Yay for parallelization!

And now for the clincher: compression algorithms work much better when it can find repeating patterns. You could compress AABBBBBBCCCCCCCCCCCCCCCC as 2A6B16C but ABCABCBCBCBCCCCCCCCCCCCCC wouldn't get as small (well, actually, in this case it would, but trust me :-) ). So once again, less reading. And writing too.

So we read a lot less data to answer common queries, it's potentially faster to read and write in parallel, and compression tends to work much better.

Columnar is great when your input side is large, and your output is a filtered subset: from big to little is great. Not as beneficial when the input and outputs are about the same.

But in our case, Impala took our old Hive queries that ran in 5, 10, 20 or 30 minutes, and finished most in a few seconds or a minute.

Hope this helps answer at least part of your question!

I think it isn't bad idea to use get_object_or_404()

from django.shortcuts import get_object_or_404

def my_view(request):
    my_object = get_object_or_404(MyModel, pk=1)

This example is equivalent to:

from django.http import Http404

def my_view(request):
    try:
        my_object = MyModel.objects.get(pk=1)
    except MyModel.DoesNotExist:
        raise Http404("No MyModel matches the given query.")

You can read more about get_object_or_404() in django online documentation.

I ran into this issue on GKE and the reason was no credentials for docker.

Running this resolved it:

gcloud auth configure-docker

They are essentially the same but using provides alias templates which is quite useful. One good example I could find is as follows:

namespace std {
 template<typename T> using add_const_t = typename add_const<T>::type;
}

So, we can use std::add_const_t<T> instead of typename std::add_const<T>::type

What you need is this:

a, b, c = [0,3,5] # Unpack the list, now a, b, and c are ints
a = 1             # `a` did equal 0, not [0,3,5]
print(a)
print(b)
print(c)

As an alternative to the other answers, django-devserver outputs SQL to the console.

Parcelable much faster than serializable with Binder, because serializable use reflection and cause many GC. Parcelable is design to optimize to pass object.

Here's link to reference. http://www.developerphil.com/parcelable-vs-serializable/

This is how I usually do it. A simple number of days perspective of B minus A.

DATE_PART('day', MAX(joindate) - MIN(joindate)) as date_diff

You can write your For loop to individually store dataframes from a list:

allocation = list()

for(i in 1:length(allocation)){
    write.csv(data.frame(allocation[[i]]), file = paste0(path, names(allocation)[i], '.csv'))
}

I'd go with the CASE WHEN also.

Depending on what you actually want to do, there may be other options though, like using an outer join or whatever, but that doesn't seem to be what you need in this case.

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

Actually, the standard shell is Bourne shell (sh). /bin/sh on Linux is actually bash, but if you're aiming for cross-platform scripts, you're better off sticking to features of the original Bourne shell or writing it in something like perl.

The following PHP settings in php.ini if set to non-existent directory can also raise

Filter using wildcards:

Get-ChildItem -Filter CopyForBuild* -Include *.bat,*.cmd -Exclude *.old.cmd,*.old.bat -Recurse

Filtering using a regular expression:

Get-ChildItem -Path "V:\Myfolder" -Recurse

Check out the boost NumericConversion library. It will allow to explicitly control how you want to deal with issues like overflow handling and truncation.

Use to_datetime, there is no need for a format string the parser is man/woman enough to handle it:

In [51]:
pd.to_datetime(df['I_DATE'])

Out[51]:
0   2012-03-28 14:15:00
1   2012-03-28 14:17:28
2   2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]

To access the date/day/time component use the dt accessor:

In [54]:
df['I_DATE'].dt.date

Out[54]:
0    2012-03-28
1    2012-03-28
2    2012-03-28
dtype: object

In [56]:    
df['I_DATE'].dt.time

Out[56]:
0    14:15:00
1    14:17:28
2    14:50:50
dtype: object

You can use strings to filter as an example:

In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]

Out[59]:
         date
35 2015-02-05
36 2015-02-06
37 2015-02-07
38 2015-02-08
39 2015-02-09

You need to delete your old db folder and recreate new one. It will resolve your issue.

Comparing strings in a case insensitive way seems trivial, but it's not. I will be using Python 3, since Python 2 is underdeveloped here.

The first thing to note is that case-removing conversions in Unicode aren't trivial. There is text for which text.lower() != text.upper().lower(), such as "ß":

"ß".lower()
#>>> 'ß'

"ß".upper().lower()
#>>> 'ss'

But let's say you wanted to caselessly compare "BUSSE" and "Buße". Heck, you probably also want to compare "BUSSE" and "BU?E" equal - that's the newer capital form. The recommended way is to use casefold:

str.casefold()

Return a casefolded copy of the string. Casefolded strings may be used for caseless matching.

Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. [...]

Do not just use lower. If casefold is not available, doing .upper().lower() helps (but only somewhat).

Then you should consider accents. If your font renderer is good, you probably think "ê" == "e^" - but it doesn't:

"ê" == "e^"
#>>> False

This is because the accent on the latter is a combining character.

import unicodedata

[unicodedata.name(char) for char in "ê"]
#>>> ['LATIN SMALL LETTER E WITH CIRCUMFLEX']

[unicodedata.name(char) for char in "e^"]
#>>> ['LATIN SMALL LETTER E', 'COMBINING CIRCUMFLEX ACCENT']

The simplest way to deal with this is unicodedata.normalize. You probably want to use NFKD normalization, but feel free to check the documentation. Then one does

unicodedata.normalize("NFKD", "ê") == unicodedata.normalize("NFKD", "e^")
#>>> True

To finish up, here this is expressed in functions:

import unicodedata

def normalize_caseless(text):
    return unicodedata.normalize("NFKD", text.casefold())

def caseless_equal(left, right):
    return normalize_caseless(left) == normalize_caseless(right)

You should use the .End(xlup) but instead of using 65536 you might want to use:

sheetvar.Rows.Count

That way it works for Excel 2007 which I believe has more than 65536 rows

I found a hack because i really need this my self.

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=
    (MyclassFragment)getSupportFragmentManager().findFragmentById(R.id.idFragment);

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

By adding your own "Exception Handling Middleware", makes it hard to reuse some good built-in logic of Exception Handler like send an "RFC 7807-compliant payload to the client" when an error happens.

What I made was to extend built-in Exception handler outside of the Startup.cs class to handle custom exceptions or override the behavior of existing ones. For example, an ArgumentException and convert into BadRequest without changing the default behavior of other exceptions:

on the Startup.cs add:

app.UseExceptionHandler("/error");

and extend ErrorController.cs with something like this:

using System;
using Microsoft.AspNetCore.Diagnostics;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Hosting;

namespace Api.Controllers
{
    [ApiController]
    [ApiExplorerSettings(IgnoreApi = true)]
    [AllowAnonymous]
    public class ErrorController : ControllerBase
    {
        [Route("/error")]
        public IActionResult Error(
            [FromServices] IWebHostEnvironment webHostEnvironment)
        {
            var context = HttpContext.Features.Get<IExceptionHandlerFeature>();
            var exceptionType = context.Error.GetType();
            
            if (exceptionType == typeof(ArgumentException)
                || exceptionType == typeof(ArgumentNullException)
                || exceptionType == typeof(ArgumentOutOfRangeException))
            {
                if (webHostEnvironment.IsDevelopment())
                {
                    return ValidationProblem(
                        context.Error.StackTrace,
                        title: context.Error.Message);
                }

                return ValidationProblem(context.Error.Message);
            }

            if (exceptionType == typeof(NotFoundException))
            {
                return NotFound(context.Error.Message);
            }

            if (webHostEnvironment.IsDevelopment())
            {
                return Problem(
                    context.Error.StackTrace,
                    title: context.Error.Message
                    );
            }
            
            return Problem();
        }
    }
}

Note that:

1. NotFoundException is a custom exception and all you need to do is throw new NotFoundException(null); or throw new ArgumentException("Invalid argument.");
2. You should not serve sensitive error information to clients. Serving errors is a security risk.

The simplest way to insert a new line between echo statements is to insert an echo without arguments, for example:

echo Create the snapshots
echo
echo Snapshot created

That is, echo without any arguments will print a blank line.

Another alternative to use a single echo statement with the -e flag and embedded newline characters \n:

echo -e "Create the snapshots\n\nSnapshot created"

However, this is not portable, as the -e flag doesn't work consistently in all systems. A better way if you really want to do this is using printf:

printf "Create the snapshots\n\nSnapshot created\n"

This works more reliably in many systems, though it's not POSIX compliant. Notice that you must manually add a \n at the end, as printf doesn't append a newline automatically as echo does.

I had a similar problem using Tomcat against Oracle. I DID have the context.xml in the META-INF directory, on the disc. This file was not showing in the eclipse project though. A simple hit on the F5 refresh and the context.xml file appeared and eclipse published it. Everything worked past that. Hope this helps someone.

Try hitting F5 in eclipse

About the Implicit Objects of the Unified Expression Language, the Java EE 5 Tutorial writes:

Implicit Objects

The JSP expression language defines a set of implicit objects:

• pageContext: The context for the JSP page. Provides access to various objects including:
  • servletContext: The context for the JSP page’s servlet and any web components contained in the same application. See Accessing the Web Context.
  • session: The session object for the client. See Maintaining Client State.
  • request: The request triggering the execution of the JSP page. See Getting Information from Requests.
  • response: The response returned by the JSP page. See Constructing Responses.
• In addition, several implicit objects are available that allow easy access to the following objects:
  • param: Maps a request parameter name to a single value
  • paramValues: Maps a request parameter name to an array of values
  • header: Maps a request header name to a single value
  • headerValues: Maps a request header name to an array of values
  • cookie: Maps a cookie name to a single cookie
  • initParam: Maps a context initialization parameter name to a single value
• Finally, there are objects that allow access to the various scoped variables described in Using Scope Objects.
  • pageScope: Maps page-scoped variable names to their values
  • requestScope: Maps request-scoped variable names to their values
  • sessionScope: Maps session-scoped variable names to their values
  • applicationScope: Maps application-scoped variable names to their values

The interesting parts are in bold :)

So, to answer your question, you should be able to access it like this (using EL):

${param.accountID}

Or, using JSP Scriptlets (not recommended):

<%
    String accountId = request.getParameter("accountID");
%>

As per my usage above v.4 this gonna work

$('#selectID').on("select2:select", function(e) { 
    //var value = e.params.data;  Using {id,text format}
});

And for less then v.4 this gonna work:

$('#selectID').on("change", function(e) { 
   //var value = e.params.data; Using {id,text} format
});

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

Why not add "display: none;" to the divs style attribute? Thats all JQuery's .hide() function does.

I wrote simple code for it without any third-party library. This code is only for a horizontal splitter (vertical is the same).

function onload()
{
    dragElement( document.getElementById("separator"), "H" );
}

// This function is used for dragging and moving
function dragElement( element, direction, handler )
{
  // Two variables for tracking positions of the cursor
  const drag = { x : 0, y : 0 };
  const delta = { x : 0, y : 0 };
  /* If present, the handler is where you move the DIV from
     otherwise, move the DIV from anywhere inside the DIV */
  handler ? ( handler.onmousedown = dragMouseDown ): ( element.onmousedown = dragMouseDown );

  // A function that will be called whenever the down event of the mouse is raised
  function dragMouseDown( e )
  {
    drag.x = e.clientX;
    drag.y = e.clientY;
    document.onmousemove = onMouseMove;
    document.onmouseup = () => { document.onmousemove = document.onmouseup = null; }
  }

  // A function that will be called whenever the up event of the mouse is raised
  function onMouseMove( e )
  {
    const currentX = e.clientX;
    const currentY = e.clientY;

    delta.x = currentX - drag.x;
    delta.y = currentY - drag.y;

    const offsetLeft = element.offsetLeft;
    const offsetTop = element.offsetTop;


    const first = document.getElementById("first");
    const second = document.getElementById("second");
    let firstWidth = first.offsetWidth;
    let secondWidth = second.offsetWidth;
    if (direction === "H" ) // Horizontal
    {
        element.style.left = offsetLeft + delta.x + "px";
        firstWidth += delta.x;
        secondWidth -= delta.x;
    }
    drag.x = currentX;
    drag.y = currentY;
    first.style.width = firstWidth + "px";
    second.style.width = secondWidth + "px";
  }
}

.splitter {
    width: 500px;
    height: 100px;
    display: flex;
}

#separator {
    cursor: col-resize;
    background: url(https://raw.githubusercontent.com/RickStrahl/jquery-resizable/master/assets/vsizegrip.png) center center no-repeat #535353;
    width: 10px;
    height: 100px;
    min-width: 10px;
}

#first {
    background-color: green;
    width: 100px;
    height: 100px;
    min-width: 10px;
}

#second {
    background-color: red;
    width: 390px;
    height: 100px;
    min-width: 10px;
}

<html>

    <head>
        <link rel="stylesheet" href="T10-Splitter.css">
        <script src="T10-Splitter.js"></script>
    </head>

    <body onload="onload()">
        <div class="splitter">

Well; this works as well:

home = "$System.env.HOME"

It's not clear what you're aiming for.

Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq

Save your JSON example to a file, say ex.json and then

yq -y '.' ex.json

I'd recommend using ActiveRecord::Base.connection.exec_query instead of ActiveRecord::Base.connection.execute which returns a ActiveRecord::Result (available in rails 3.1+) which is a bit easier to work with.

Then you can access it in various the result in various ways like .rows, .each, or .to_hash

From the docs:

result = ActiveRecord::Base.connection.exec_query('SELECT id, title, body FROM posts')
result # => #<ActiveRecord::Result:0xdeadbeef>


# Get the column names of the result:
result.columns
# => ["id", "title", "body"]

# Get the record values of the result:
result.rows
# => [[1, "title_1", "body_1"],
      [2, "title_2", "body_2"],
      ...
     ]

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

# ActiveRecord::Result also includes Enumerable.
result.each do |row|
  puts row['title'] + " " + row['body']
end

Android Device Monitor is a part of ANDROID SDK.

You can found it here: C:\android-sdk\tools\lib\monitor-x86\monitor.exe or C:\android-sdk\tools\lib\monitor-x86_64\monitor.exe.

Run it for monitring or exploring files on the AVD.

From the git checkout docs

git checkout [-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...

--ours
--theirs
When checking out paths from the index, check out stage #2 (ours) or #3 (theirs) for unmerged paths.

The index may contain unmerged entries because of a previous failed merge. By default, if you try to check out such an entry from the index, the checkout operation will fail and nothing will be checked out. Using -f will ignore these unmerged entries. The contents from a specific side of the merge can be checked out of the index by using --ours or --theirs. With -m, changes made to the working tree file can be discarded to re-create the original conflicted merge result.

Assign something to your strings. This will definitely help.

padding-left is what controls the indentation of ul not margin-left.

Compare: Here's setting padding-left to 0, notice all the indentation disappears.

ul {
  padding-left: 0;
}

<ul>
  <li>section a
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>
<ul>
  <li>section b
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>

and here's setting margin-left to 0px. Notice the indentation does NOT change.

ul {
  margin-left: 0;
}

<ul>
  <li>section a
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>
<ul>
  <li>section b
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>

I know OP asked about the utils::read.csv function, but let me provide an answer for these that come here searching how to do it using readr::read_csv from the tidyverse.

read_csv ("test.csv", col_names=FALSE, col_types = cols (.default = "c", time = "i"))

This should set the default type for all columns as character, while time would be parsed as integer.

In addition to already existing answers and to make this more confusing:

In Python, variables that are only referenced inside a function are implicitly global. If a variable is assigned a new value anywhere within the function’s body, it’s assumed to be a local. If a variable is ever assigned a new value inside the function, the variable is implicitly local, and you need to explicitly declare it as ‘global’.

Though a bit surprising at first, a moment’s consideration explains this. On one hand, requiring global for assigned variables provides a bar against unintended side-effects. On the other hand, if global was required for all global references, you’d be using global all the time. You’d have to declare as global every reference to a built-in function or to a component of an imported module. This clutter would defeat the usefulness of the global declaration for identifying side-effects.

Source: What are the rules for local and global variables in Python?.

A generic version of @Kevan's answer above, using Reactive Extensions.

public static Task<T> TimeoutAfter<T>(this Task<T> task, TimeSpan timeout, IScheduler scheduler)
{
    return task.ToObservable().Timeout(timeout, scheduler).ToTask();
}

With optional Scheduler:

public static Task<T> TimeoutAfter<T>(this Task<T> task, TimeSpan timeout, Scheduler scheduler = null)
{
    return scheduler is null 
       ? task.ToObservable().Timeout(timeout).ToTask() 
       : task.ToObservable().Timeout(timeout, scheduler).ToTask();
}

BTW: When a Timeout happens, a timeout exception will be thrown

You can definitely use the section tag as a container. It is there to group content in a more semantically significant way than with a div or as the html5 spec says:

The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading. http://www.w3.org/TR/html5/sections.html#the-section-element

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

First make sure you correct your program:

#include <stdio.h>

int main(void) {
   printf("Hello, world!\n"); //printf instead of pintf
   return 0;
}

Save the file as HelloWorld.c and type in the terminal:

gcc -o HelloWorld HelloWorld.c

Afterwards just run the executable like this:

./HelloWorld

You should be seeing Hello World!

What about just using the UniqueID of the processor?

I haven't done much testing with this but it seems to work. Here's what I came up with:

namespace OrtzIRC.WPF
{
    using System;
    using System.Windows;
    using OrtzIRC.WPF.ViewModels;

    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        private MainViewModel viewModel = new MainViewModel();
        private MainWindow window = new MainWindow();

        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            viewModel.RequestClose += ViewModelRequestClose;

            window.DataContext = viewModel;
            window.Closing += Window_Closing;
            window.Show();
        }

        private void ViewModelRequestClose(object sender, EventArgs e)
        {
            viewModel.RequestClose -= ViewModelRequestClose;
            window.Close();
        }

        private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            window.Closing -= Window_Closing;
            viewModel.RequestClose -= ViewModelRequestClose; //Otherwise Close gets called again
            viewModel.CloseCommand.Execute(null);
        }
    }
}

You've been shown PadLeft and PadRight. This will fill in the missing PadCenter.

public static class StringUtils
{
    public static string PadCenter(this string s, int width, char c)
    {
        if (s == null || width <= s.Length) return s;

        int padding = width - s.Length;
        return s.PadLeft(s.Length + padding / 2, c).PadRight(width, c);
    }
}

Note to self: don't forget to update own CV: "One day, I even fixed Joel Coehoorn's code!" ;-D -Serge

Try this:

private byte[] Hex2Bin(string hex) 
{
 if ((hex == null) || (hex.Length < 1)) {
  return new byte[0];
 }
 int num = hex.Length / 2;
 byte[] buffer = new byte[num];
 num *= 2;
 for (int i = 0; i < num; i++) {
  int num3 = int.Parse(hex.Substring(i, 2), NumberStyles.HexNumber);
  buffer[i / 2] = (byte) num3;
  i++;
 }
 return buffer;
}

private string Bin2Hex(byte[] binary) 
{
 StringBuilder builder = new StringBuilder();
 foreach(byte num in binary) {
  if (num > 15) {
   builder.AppendFormat("{0:X}", num);
  } else {
   builder.AppendFormat("0{0:X}", num); /////// ?? 15 ???? 0
  }
 }
 return builder.ToString();
}

Because setting the div's display style property to "" doesn't change anything in the CSS rule itself. That basically just creates an "empty," inline CSS rule, which has no effect beyond clearing the same property on that element.

You need to set it to something that has a value:

document.getElementById('mybox').style.display = "block";

What you're doing would work if you were replacing an inline style on the div, like this:

<div id="myBox" style="display: none;"></div>

document.getElementById('mybox').style.display = "";

  if (window.sidebar) { // Mozilla Firefox Bookmark
     window.sidebar.addPanel(document.title,location.href,"");

It adds the bookmark but in the sidebar.

• Always use -r with read.
• There is no need to use cut, you can stick with pure bash solutions.
  • In this case passing read a 2nd var (_) to catch the additional "fields"
• Prefer [[ ]] over [ ].
• Use arithmetic expressions.
• Do not forget to quote variables! Link includes other pitfalls as well

while read -r country _; do
  if [[ $country = 'US' ]]; then
    ((USCOUNTER++))
    echo "US counter $USCOUNTER"
  fi
done < "$FILE"

Assuming they are in a file or array just do the replace as a batch (i.e. on all at once):

$input = str_replace(array('.', ','), array('', '.'), $input); 

and then process the numbers from there taking full advantage of PHP's loosely typed nature.

The for loop can only contain three parameters, you have used 4. Please restate the question, what do you want to achieve?
