I don't mention basics like syntax highlighting as I expect these by default.

This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?

We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

Submit edits to the spreadsheet

This error is usually encountered when inserting a record in a table where one of the columns is a VARCHAR or CHAR data type and the length of the value being inserted is longer than the length of the column.

I am not satisfied how Microsoft decided to inform with this "dry" response message, without any point of where to look for the answer.

Edit (for ASP.NET)

After you edited your question it's cler you're using ASP.NET. Things are pretty different there (because in that case a roundtrip to server is pretty discouraged). You can do same things with JavaScript (but to handle globalization with toUpperCase() may be a pain) or you can use CSS classes (relying on browsers implementation). Simply declare this CSS rule:

.upper-case
{
    text-transform: uppercase
}

And add upper-case class to your text-box:

<asp:TextBox ID="TextBox1" CssClass="upper-case" runat="server"/>

General (Old) Answer

but it capitalize characters after pressing Enter key.

It depends where you put that code. If you put it in, for example, TextChanged event it'll make upper case as you type.

You have a property that do exactly what you need: CharacterCasing:

TextBox1.CharacterCasing = CharacterCasing.Upper;

It works more or less but it doesn't handle locales very well. For example in German language ß is SS when converted in upper case (Institut für Deutsche Sprache) and this property doesn't handle that.

You may mimic CharacterCasing property adding this code in KeyPress event handler:

e.KeyChar = Char.ToUpper(e.KeyChar);

Unfortunately .NET framework doesn't handle this properly and upper case of sharp s character is returned unchanged. An upper case version of ß exists and it's ? and it may create some confusion, for example a word containing "ss" and another word containing "ß" can't be distinguished if you convert in upper case using "SS"). Don't forget that:

However, in 2010 the use of the capital sharp s became mandatory in official documentation when writing geographical names in all-caps.

There isn't much you can do unless you add proper code for support this (and others) subtle bugs in .NET localization. Best advice I can give you is to use a custom dictionary per each culture you need to support.

Finally don't forget that this transformation may be confusing for your users: in Turkey, for example, there are two different versions of i upper case letter.

If text processing is important in your application you can solve many issues using specialized DLLs for each locale you support like Word Processors do.

What I usually do is to do not use standard .NET functions for strings when I have to deal with culture specific issues (I keep them only for text in invariant culture). I create a Unicode class with static methods for everything I need (character counting, conversions, comparison) and many specialized derived classes for each supported language. At run-time that static methods will user current thread culture name to pick proper implementation from a dictionary and to delegate work to that. A skeleton may be something like this:

abstract class Unicode
{
    public static string ToUpper(string text)
    {
        return GetConcreteClass().ToUpperCore(text);
    }

    protected virtual string ToUpperCore(string text)
    {
        // Default implementation, overridden in derived classes if needed
        return text.ToUpper();
    }

    private Dictionary<string, Unicode> _implementations;

    private Unicode GetConcreteClass()
    {
        string cultureName = Thread.Current.CurrentCulture.Name;

        // Check if concrete class has been loaded and put in dictionary
        ...

        return _implementations[cultureName];
    }
}

I'll then have an implementation specific for German language:

sealed class German : Unicode
{
    protected override string ToUpperCore(string text)
    {
        // Very naive implementation, just to provide an example
        return text.ToUpper().Replace("ß", "?");
    }
}

True implementation may be pretty more complicate (not all OSes supports upper case ?) but take as a proof of concept. See also this post for other details about Unicode issues on .NET.

Solution for people who prefer clicking:

1. Install sourcetree (it is free)

2. Check how your commits look like. Most likely you have something similar to this

3. Right click on parent commit. In our case it is master branch.

4. You can squash commit with previous one by clicking a button. In our case we have to click 2 times. You can also change commit message

5. Results are awesome and we are ready to push!

Side note: If you were pushing your partial commits to remote you have to use force push after squash

I encountered a similar error while trying to import data using pandas, The first column on my dataset had spaces before the start of the words. I removed the spaces and it worked like a charm!!

Using the links posted in the previous answers, I coded a little example in C++ using a Virtual Serial Port. I pushed the code into GitHub: https://github.com/cymait/virtual-serial-port-example .

The code is pretty self explanatory. First, you create the master process by running ./main master and it will print to stderr the device is using. After that, you invoke ./main slave device, where device is the device printed in the first command.

And that's it. You have a bidirectional link between the two process.

Using this example you can test you the application by sending all kind of data, and see if it works correctly.

Also, you can always symlink the device, so you don't need to re-compile the application you are testing.

The output file needs to be opened in binary mode:

f = open('varstor.txt','w')

needs to be:

f = open('varstor.txt','wb')

string name= "abc";
IList<string> strList = new List<string>() { "abc",  "def", "ghi", "jkl", "mno" };
if (strList.Contains(name))
{
  Console.WriteLine("Got It");
}

/////////////////   OR ////////////////////////

IList<int> num = new List<int>();
num.Add(10);
num.Add(20);
num.Add(30);
num.Add(40);

Console.WriteLine(num.Count);   // to count the total numbers in the list

if(num.Contains(20)) {
    Console.WriteLine("Got It");    // if condition to find the number from list
}

I up-voted you as your method is simple. I did make only a couple of slight amends as sometimes the event fires even though there are no bytes to send - On my machine it did it when I clicked the remove button on a file.

myDropzone.on("totaluploadprogress", function(totalPercentage, totalBytesToBeSent, totalBytesSent ){
            if(totalPercentage >= 100 && totalBytesSent) {
                // All done! Call func here
            }
        });

You need to write() the read() data into the new file:

ssize_t nrd;
int fd;
int fd1;

fd = open(aa[1], O_RDONLY);
fd1 = open(aa[2], O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
while (nrd = read(fd,buffer,50)) {
    write(fd1,buffer,nrd);
}

close(fd);
close(fd1);

Update: added the proper opens...

Btw, the O_CREAT can be OR'd (O_CREAT | O_WRONLY). You are actually opening too many file handles. Just do the open once.

If you haven't pushed that change yet, git reset --hard HEAD^

Otherwise, reverting the revert is perfectly fine.

Another way is to git checkout HEAD^^ -- . and then git add -A && git commit.

From JavaEE docs ServletResponse#setContentType

• Sets the content type of the response being sent to the client, if the response has not been committed yet.

• The given content type may include a character encoding specification, for example,

response.setContentType("text/html;charset=UTF-8");

• The response's character encoding is only set from the given content type if this method is called before getWriter is called.

• This method may be called repeatedly to change content type and character encoding.

• This method has no effect if called after the response has been committed. It does not set the response's character encoding if it is called after getWriter has been called or after the response has been committed.

• Containers must communicate the content type and the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the Content-Type header is used.

use

app:backgroundTint="@color/orange" in

<com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/id_share_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/share"
        app:backgroundTint="@color/orange"
        app:fabSize="mini"
        app:layout_anchorGravity="end|bottom|center" />

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

In linguistics, to divide language into small components that can be analyzed. For example, parsing this sentence would involve dividing it into words and phrases and identifying the type of each component (e.g.,verb, adjective, or noun).

Parsing is a very important part of many computer science disciplines. For example, compilers must parse source code to be able to translate it into object code. Likewise, any application that processes complex commands must be able to parse the commands. This includes virtually all end-user applications.

Parsing is often divided into lexical analysis and semantic parsing. Lexical analysis concentrates on dividing strings into components, called tokens, based on punctuationand other keys. Semantic parsing then attempts to determine the meaning of the string.

http://www.webopedia.com/TERM/P/parse.html

All of the above work, but also have to work around a problem (escapes and special characters) that doesn't need to occur in the first place: Special characters when the variable is expanded by the shell. Just don't do that (variable expansion) in the first place. Use the variable directly, without expansion.

Also, if your variable contains a secret and you want to copy that secret into a file, you might want to not have expansion in the command line as tracing/command echo of the shell commands might reveal the secret. Means, all answers which use $var in the command line may have a potential security risk by exposing the variable contents to tracing and logging of the shell.

Use this:

printenv var >file

That means, in case of the OP question:

printenv var >"$destfile"

Note: variable names are case sensitive.

So before I found this post, I successfully found this to work.

Model._meta.fields

It works equally as

Model._meta.get_fields()

I'm not sure what the difference is in the results, if there is one. I ran this loop and got the same output.

for field in Model._meta.fields:
    print(field.name)

If you need to redirect out of your angular application use $window.location. That was my case; hopefully someone will find it useful.

String string="this is a text";
editText.setText(string)

I have found String to be a useful Indirect Subclass of CharSequence

http://developer.android.com/reference/android/widget/TextView.html find setText(CharSequence text)

http://developer.android.com/reference/java/lang/CharSequence.html

It shouldn't be HTTP headers if the file has been downloaded successfully and it's the same file that you can open from OI.

A shot in the dark, but could it be that you are not allowing installation from unknown sources, and that OI is somehow bypassing that?

Settings > Applications > Unknown sources...

Edit

Answer extracted from comments which worked. Ensure the Content-Type is set to application/vnd.android.package-archive

Using SelectionRange you will get the Start and End date.

private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
    var startDate = monthCalendar1.SelectionRange.Start.ToString("dd MMM yyyy");
    var endDate = monthCalendar1.SelectionRange.End.ToString("dd MMM yyyy");
}

If you want to update the maximum number of days that can be selected, then set MaxSelectionCount property. The default is 7.

// Only allow 21 days to be selected at the same time.
monthCalendar1.MaxSelectionCount = 21;

I had this problem a couple hours ago when I exported my projects from Eclipse to Android Studio. Unfortunately, the top answers here didn't work for me.

Anyway, creating a new project instead of opening an old one did the trick for me as what Thomas Kaliakos mentioned on his comment here

I had to mess around with the project..and at some point it worked. I don't know how though. My guess would be that creating a new project and adding your source code would work every time. Sorry for not being very clear, but honestly I was surprized even myself that it worked. – Thomas Kaliakos Oct 15 '13 at 4:08

If you are on Mac, make sure you enable annotation processing (tick the checkbox) at these 2 places.

1.) Intellij IDEA -> Preferences -> Compiler -> Annotation Processors

2.) File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors

And then

3.) Intellij IDEA -> Preferences -> Plugins ->Browse Repositories-> Search for "Lombok"-> install plugin -> Apply and restart IDEA

4.) And then probably restart Intellij IDEA.

This is my IntelliJ IDEA and Mac Version - IntelliJ IDEA 2017.1.5 Build #IU-171.4694.70 --- Mac OS X 10.12

Based on what @J. Calleja said, you have two choices

Method 1 - Random access

If you want to random access the element of Mat, just simply use

Mat.at<data_Type>(row_num, col_num) = value;

Method 2 - Continuous access

If you want to continuous access, OpenCV provides Mat iterator compatible with STL iterator and it's more C++ style

MatIterator_<double> it, end;
for( it = I.begin<double>(), end = I.end<double>(); it != end; ++it)
{
    //do something here
}

or

for(int row = 0; row < mat.rows; ++row) {
    float* p = mat.ptr(row); //pointer p points to the first place of each row
    for(int col = 0; col < mat.cols; ++col) {
         *p++;  // operation here
    }
}

If you have any difficulty to understand how Method 2 works, I borrow the picture from a blog post in the article Dynamic Two-dimensioned Arrays in C, which is much more intuitive and comprehensible.

See the picture below.

This worked for me:

<html>
<head>
<title>scroll</title>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js" type="text/javascript"></script>

</head>
<body>

<style>
div.container {
  overflow:hidden;
  width:200px;
  height:200px;
}
div.content {
  position:relative;
  width:200px;
  height:200px;  
  overflow:hidden;
  top:0;
}
</style>

<div class="container">
  <p>
    <a href="javascript:up();"><img src="/images/img_flecha_left.png" class="up" /></a>
    <a href="javascript:down();"><img src="/images/img_flecha_left.png" class="down" /></a>   

  </p>
  <div class="content">
    <p>Hello World</p><p>Hello World</p>
    <p>Hello World</p>
    <p>Hello World</p>
    <p>Hello World</p>
    <p>Hello World</p>
    <p>Hello World</p>
    <p>Hello World</p>
    <p>Hello World</p>
  </div>
</div>

<script>
function up() {
    var topVal = $(".content").css("top"); //alert(topVal);
    var val=parseInt(topVal.replace("px",""));
    val=val-20;
    $(".content").css("top", val+"px");    
}
function down() {
    var topVal = $(".content").css("top"); //alert(topVal);
    var val=parseInt(topVal.replace("px",""));
    val=val+20;
    $(".content").css("top", val+"px");  
}
</script>
</body>
</html>

You can do it just like with a property:

FieldInfo fi = typeof(Foo).GetField("_bar", BindingFlags.NonPublic | BindingFlags.Instance);
if (fi.GetCustomAttributes(typeof(SomeAttribute)) != null)
    ...

This worked for me

sudo apt-get install libc6-i386 lib32stdc++6 lib32gcc1 lib32ncurses5

using System.IO;

DirectoryInfo di = new DirectoryInfo(folder);
FileInfo[] files = di.GetFiles("*.xml");

public static <T> List<T> merge(@Nonnull final List<T>... list) {
    // calculate length first
    int mergedLength = 0;
    for (List<T> ts : list) {
      mergedLength += ts.size();
    }

    final List<T> mergedList = new ArrayList<>(mergedLength);

    for (List<T> ts : list) {
      mergedList.addAll(ts);
    }

    return mergedList;
  }

It's worth mentioning that the validation properties are different for forms and form elements (note that touched and untouched are for fields only):

Input fields have the following states:

$untouched The field has not been touched yet
$touched The field has been touched
$pristine The field has not been modified yet
$dirty The field has been modified
$invalid The field content is not valid
$valid The field content is valid

They are all properties of the input field, and are either true or false.

Forms have the following states:

$pristine No fields have been modified yet
$dirty One or more have been modified
$invalid The form content is not valid
$valid The form content is valid
$submitted The form is submitted

They are all properties of the form, and are either true or false.

I had the same issue and couldn't use SVN after the update,

Just in case if doing xcode-select --install didn't fix the issue,

You might see,

svn: error: The subversion command line tools are no longer provided by Xcode.

Refer : https://developer.apple.com/documentation/macos_release_notes/macos_catalina_10_15_release_notes

Try installing the svn by brew

brew install svn

This should get you going.

I find easiest to use: cd $home\Desktop\

will take you to current user desktop

In my case, I needed to retrieve the username to enable the script to change the path, ie. c:\users\%username%. I needed to start the script by changing the path to the users desktop. I was able to do this, with help from above and elsewhere, by using the get-location applet.

You may have another, or even better way to do it, but this worked for me:

$Path = Get-Location

Set-Location $Path\Desktop

autowidth: true

worked perfectly for me. learnt from here.

If you really must completely strip out the single quotes you can do this:

Replace(@strip, '''', '')

However, ordinarily you'd replace ' with '' and this will make SQL Server happy when querying the database. The trick with any of the built-in SQL functions (like replace) is that they too require you to double up your single quotes.

So to replace ' with '' in code you'd do this:

Of course... in some situations you can avoid having to do this entirely if you use parameters when querying the database. Say you're querying the database from a .NET application, then you'd use the SqlParameter class to feed the SqlCommand parameters for the query and all of this single quote business will be taken care of automatically. This is usually the preferred method as SQL parameters will also help prevent SQL injection attacks.

Here are functions to guarantee logical right shift and arithmetic right shift of an int in C:

int logicalRightShift(int x, int n) {
    return (unsigned)x >> n;
}
int arithmeticRightShift(int x, int n) {
    if (x < 0 && n > 0)
        return x >> n | ~(~0U >> n);
    else
        return x >> n;
}

Since you're using requests, you should use the response's json method.

import requests

response = requests.get(...)
data = response.json()

It autodetects which decoder to use.

Here is a simple example of group by in .net core 2.1

var query = this.DbContext.Notifications.
            Where(n=> n.Sent == false).
            GroupBy(n => new { n.AppUserId })
            .Select(g => new { AppUserId = g.Key, Count =  g.Count() });

var query2 = from n in this.DbContext.Notifications
            where n.Sent == false
            group n by n.AppUserId into g
            select new { id = g.Key,  Count = g.Count()};

Which translates to:

SELECT [n].[AppUserId], COUNT(*) AS [Count]
FROM [Notifications] AS [n]
WHERE [n].[Sent] = 0
GROUP BY [n].[AppUserId]

You can run a python script via php, and outputs on browser.

Basically you have to call the python script this way:

$command = "python /path/to/python_script.py 2>&1";
$pid = popen( $command,"r");
while( !feof( $pid ) )
{
 echo fread($pid, 256);
 flush();
 ob_flush();
 usleep(100000);
}
pclose($pid);

Note: if you run any time.sleep() in you python code, it will not outputs the results on browser.

Here's my solution, i would love anyone's opinion on this, it's simple for beginners

import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.spec.InvalidKeySpecException;
import java.security.spec.KeySpec;
import java.util.Base64;
import java.util.Base64.Encoder;
import java.util.Scanner;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.PBEKeySpec;

public class Cryptography {

    public static void main(String[] args) throws NoSuchAlgorithmException, InvalidKeySpecException {
        Encoder encoder = Base64.getUrlEncoder().withoutPadding();
        System.out.print("Password: ");
        String strPassword = new Scanner(System.in).nextLine();
        byte[] bSalt = Salt();
        String strSalt = encoder.encodeToString(bSalt); // Byte to String
        System.out.println("Salt: " + strSalt);
        System.out.println("String to be hashed: " + strPassword + strSalt);
        String strHash = encoder.encodeToString(Hash(strPassword, bSalt)); // Byte to String
        System.out.println("Hashed value (Password + Salt value): " + strHash);
    }

    private static byte[] Salt() {
        SecureRandom random = new SecureRandom();
        byte salt[] = new byte[6];
        random.nextBytes(salt);
        return salt;
    }

    private static byte[] Hash(String password, byte[] salt) throws NoSuchAlgorithmException, InvalidKeySpecException {
        KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, 65536, 128);
        SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
        byte[] hash = factory.generateSecret(spec).getEncoded();
        return hash;
    }

}

You can validate by just decoding the strSalt and using the same hash method:

public static void main(String[] args) throws NoSuchAlgorithmException, InvalidKeySpecException {
        Encoder encoder = Base64.getUrlEncoder().withoutPadding();
        Decoder decoder = Base64.getUrlDecoder();
        System.out.print("Password: ");
        String strPassword = new Scanner(System.in).nextLine();
        String strSalt = "Your Salt String Here";
        byte[] bSalt = decoder.decode(strSalt); // String to Byte
        System.out.println("Salt: " + strSalt);
        System.out.println("String to be hashed: " + strPassword + strSalt);
        String strHash = encoder.encodeToString(Hash(strPassword, bSalt)); // Byte to String
        System.out.println("Hashed value (Password + Salt value): " + strHash);
    }

It's an old post but I none of this solution worked for me so I'm posting my solution if anyone find this helpful.

I just had the same problem.

In my case the control I needed to disable was a user control with child dropdowns which I could disable in IE but not in chrome.

my solution was to disable each child object, not just the usercontrol, with that code:

$('#controlName').find('*').each(function () { $(this).attr("disabled", true); })

It's working for me in chrome now.

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

Here's a snippet of how to get the creation time of files in the directory and find those which have been created 3 months ago (90 days ago to be exact):

    DirectoryInfo source = new DirectoryInfo(sourceDirectoryPath);

    // Get info of each file into the directory
    foreach (FileInfo fi in source.GetFiles())
    {
        var creationTime = fi.CreationTime;

        if(creationTime < (DateTime.Now- new TimeSpan(90, 0, 0, 0)))
        {
            fi.Delete();
        }
    }

On the anaconda prompt, do a

• conda -V or conda --version to get the conda version.

Questions 1 & 2

So basically, first parameter is the object to iterate on. It can be an array or an object. If it is an object like this :

var values = {name: 'misko', gender: 'male'};

Angular will take each value one by one the first one is name, the second is gender.

If your object to iterate on is an array (also possible), like this :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]

Angular.forEach will take one by one starting by the first object, then the second object.

For each of this object, it will so take them one by one and execute a specific code for each value. This code is called the iterator function. forEach is smart and behave differently if you are using an array of a collection. Here is some exemple :

var obj = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(obj, function(value, key) {
  console.log(key + ': ' + value);
});
// it will log two iteration like this
// name: misko
// gender: male

So key is the string value of your key and value is ... the value. You can use the key to access your value like this : obj['name'] = 'John'

If this time you display an array, like this :

var values = [{ "Name" : "Thomas", "Password" : "thomasTheKing" },
           { "Name" : "Linda", "Password" : "lindatheQueen" }];
angular.forEach(values, function(value, key){
     console.log(key + ': ' + value);
});
// it will log two iteration like this
// 0: [object Object]
// 1: [object Object]

So then value is your object (collection), and key is the index of your array since :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]
// is equal to
{0: { "Name" : "Thomas", "Password" : "thomasTheKing" },
 1: { "Name" : "Linda", "Password" : "lindatheQueen" }}

I hope it answer your question. Here is a JSFiddle to run some code and test if you want : http://jsfiddle.net/ygahqdge/

Debugging your code

The problem seems to come from the fact $http.get() is an asynchronous request.

You send a query on your son, THEN when you browser end downloading it it execute success. BUT just after sending your request your perform a loop using angular.forEach without waiting the answer of your JSON.

You need to include the loop in the success function

var app = angular.module('testModule', [])
    .controller('testController', ['$scope', '$http', function($scope, $http){
    $http.get('Data/info.json').then(function(data){
         $scope.data = data;

         angular.forEach($scope.data, function(value, key){
         if(value.Password == "thomasTheKing")
           console.log("username is thomas");
         });
    });

});

This should work.

Going more deeply

The $http API is based on the deferred/promise APIs exposed by the $q service. While for simple usage patterns this doesn't matter much, for advanced usage it is important to familiarize yourself with these APIs and the guarantees they provide.

You can give a look at deferred/promise APIs, it is an important concept of Angular to make smooth asynchronous actions.

In .Net Core, follow the instructions at https://docs.microsoft.com/en-us/aspnet/core/security/enforcing-ssl

In your startup.cs add the following:

// Requires using Microsoft.AspNetCore.Mvc;
public void ConfigureServices(IServiceCollection services)
{
    services.Configure<MvcOptions>(options =>
    {
        options.Filters.Add(new RequireHttpsAttribute());
    });`enter code here`

To redirect Http to Https, add the following in the startup.cs

// Requires using Microsoft.AspNetCore.Rewrite;
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    var options = new RewriteOptions()
       .AddRedirectToHttps();

    app.UseRewriter(options);

This solution is purely using ng tag on HTML.

The solution is to limit the long text displayed with 'show more...' link at the end of it. If user click 'show more...' link, it will show the rest of the text and removed the 'show more...' link.

HTML:

<div ng-init="limitText=160">
   <p>{{ veryLongText | limitTo: limitText }} 
       <a href="javascript:void(0)" 
           ng-hide="veryLongText.length < limitText" 
           ng-click="limitText = veryLongText.length + 1" > show more..
       </a>
   </p>
</div>

I had the same problem. I think the best solution is to use log.exception, which will automatically print out stack trace and error message, such as:

try:
    pass
    log.info('Success')
except:
    log.exception('Failed')

so I am assuming this is kinda out of use now but one way to do it is actually using document.body.style.zoom=2.0; but if you do this then all of your canvas measurements will have to be divided by the zoom. Also, set the zoom higher for more aliasing. This is helpful because it is adjustable. Also if using this method, I suggest that you make functions to do the same as ctx.fillRect() etc. but with the zoom taken into account. E.g.

function fillRect(x, y, width, height) {
    var zoom = document.body.style.zoom;
    ctx.fillRect(x/zoom, y/zoom, width/zoom, height/zoom);
}

Hope this helps!

Also, a sidenote: this can be used to sharpen circle edges as well so that they don't look as blurred. Just use a zoom such as 0.5!

I run into this problem on a regular basis and often use the "add a method" solution. However, there are definitely cases where "add a method" or "compute it in the view" don't work (or don't work well). E.g. when you are caching template fragments and need some non-trivial DB computation to produce it. You don't want to do the DB work unless you need to, but you won't know if you need to until you are deep in the template logic.

Some other possible solutions:

1. Use the {% expr <expression> as <var_name> %} template tag found at http://www.djangosnippets.org/snippets/9/ The expression is any legal Python expression with your template's Context as your local scope.

2. Change your template processor. Jinja2 (http://jinja.pocoo.org/2/) has syntax that is almost identical to the Django template language, but with full Python power available. It's also faster. You can do this wholesale, or you might limit its use to templates that you are working on, but use Django's "safer" templates for designer-maintained pages.

When using Jest 21.2.1, I can see code coverage at the command line and create a coverage directory by passing --coverage to the Jest script. Below are some examples:

I tend to install Jest locally, in which case the command might look like this:

npx jest --coverage

I assume (though haven't confirmed), that this would also work if I installed Jest globally:

jest --coverage

The very sparse docs are here

When I navigated into the coverage/lcov-report directory I found an index.html file that could be loaded into a browser. It included the information printed at the command line, plus additional information and some graphical output.

Upgrading protobuf-gradle-plugin to version 0.8.10 solved my problem. Replace your existing protobuf with

classpath 'gradle.plugin.com.google.protobuf:protobuf-gradle-plugin:0.8.10'

For python markdown with attr_list extension the syntax is a little different:

{: #someid .someclass somekey='some value' }

Example:

[Click here](http://exmaple.com){: .btn .btn-primary }

Lead information paragraph
{: .lead }

I suggest you to use StringBuilder class for it and than parse it to string if you need.

System.Text.StringBuilder strBuilder = new System.Text.StringBuilder("valta is the best place in the World");
strBuilder[0] = 'M';
string str=strBuilder.ToString();

You can't change string's characters in this way, because in C# string isn't dynamic and is immutable and it's chars are readonly. For make sure in it try to use methods of string, for example, if you do str.ToLower() it makes new string and your previous string doesn't change.

As of PowerShell 6.0, Split-Path has an -Extenstion parameter. This means you can do:

$path | Split-Path -Extension

or

Split-Path -Path $path -Extension

For $path = "test.txt" both versions will return .txt, inluding the full stop.

I had the same problem. I was using Docker Toolbox on Windows Home. Instead of localhost I had to use http://192.168.99.100:8080/.

You can get the correct IP address using the command:

docker-machine ip

The above command returned 192.168.99.100 for me.

May I suggest trying to use in else if statement in your if/else statement. And if you don't want to run any code that not under any conditions you want you can just leave the else out at the end of the statement. else if can also be used for any number of diversion paths that need things to be a certain condition for each.

if(condition 1){

} else if (condition 2) {

}else {

}

First navigate to below location and open it in a text editor

<TOMCAT_HOME>/conf/tomcat-users.xml

For tomcat 7, Add the following xml code somewhere between <tomcat-users> I find the following solution.

  <role rolename="manager-gui"/>
  <user username="username" password="password" roles="manager-gui"/>

Now restart the tomcat server.

The only way to ensure code is executed is to place your setTimeout logic in a different process.

Use the child process module to spawn a new node.js program that does your logic and pass data to that process through some kind of a stream (maybe tcp).

This way even if some long blocking code is running in your main process your child process has already started itself and placed a setTimeout in a new process and a new thread and will thus run when you expect it to.

Further complication are at a hardware level where you have more threads running then processes and thus context switching will cause (very minor) delays from your expected timing. This should be neglible and if it matters you need to seriously consider what your trying to do, why you need such accuracy and what kind of real time alternative hardware is available to do the job instead.

In general using child processes and running multiple node applications as separate processes together with a load balancer or shared data storage (like redis) is important for scaling your code.

If you're using compass:

compass watch --output-style compressed

json_decode($jsondata, true);

true turns all properties to array (sequential or not)

Note that the "if ($str)" and "IsNullOrEmpty" tests don't work comparably in all instances: an assignment of $str=0 produces false for both, and depending on intended program semantics, this could yield a surprise.

"%s" will read the input until whitespace is reached.

gets might be a good place to start if you want to read a line (i.e. all characters including whitespace until a newline character is reached).

It would be the 32 bit version of eclipse , for instance if you are running the 32 bit version of eclipse in 64 bit JVM, this error will be the result.

To confirm this check for log in your configuration folder of the eclipse. Log will be as following java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM ...

try installing the either 64 bit eclipse or run in 32 bit jvm

I tried using Adam B's answer, however, it didn't work for me. Instead, I found the following workaround for adding legends to pointplots.

import matplotlib.patches as mpatches
red_patch = mpatches.Patch(color='#bb3f3f', label='Label1')
black_patch = mpatches.Patch(color='#000000', label='Label2')

In the pointplots, the color can be specified as mentioned in previous answers. Once these patches corresponding to the different plots are set up,

plt.legend(handles=[red_patch, black_patch])

And the legend ought to appear in the pointplot.

Because (amongst other reasons) it's much harder to ensure the input data is sanitized. If you use parametrized queries, as one does with PDO or mysqli you can entirely avoid the risk.

As an example, someone could use "enhzflep); drop table users" as a username. The old functions will allow executing multiple statements per query, so something like that nasty bugger can delete a whole table.

If one were to use PDO of mysqli, the user-name would end-up being "enhzflep); drop table users".

See bobby-tables.com.

I'm in a somewhat similar situation. It's not clear whether you know chunk size in bytes; I usually don't, but the number of records (lines) that is required is known:

def get_line():
     with open('4gb_file') as file:
         for i in file:
             yield i

lines_required = 100
gen = get_line()
chunk = [i for i, j in zip(gen, range(lines_required))]

Update: Thanks nosklo. Here's what I meant. It almost works, except that it loses a line 'between' chunks.

chunk = [next(gen) for i in range(lines_required)]

Does the trick w/o losing any lines, but it doesn't look very nice.

You most likely have your virtual machine’s networking set to NAT. If you set your networking to Bridged you should be able to access your host machine by its hostname. For example, if your hostname is “jsmith-Precision-7510” and you want to open http://localhost:3000/, you will be able to view that page at http://jsmith-Precision-7510:3000/.

To find your hostname, open a terminal/console and then run the command hostname. Your hostname will be outputted on the next line.

See the VirtualBox documentation for instructions on how to set your networking setttings to Bridged.

I believe my answer covers your new concerns about handling any type of line endings since both "\r\n" and "\r" are converted to Linux standard "\n" before parsing the lines.

To support the "\r" EOL character along with the regular "\n", and "\r\n" from Windows, here's what I would do:

line_num=0
text=File.open('xxx.txt').read
text.gsub!(/\r\n?/, "\n")
text.each_line do |line|
  print "#{line_num += 1} #{line}"
end

Of course this could be a bad idea on very large files since it means loading the whole file into memory.

I recommend to read Microsoft guide for use Relationships, Navigation Properties and Foreign Keys in EF Code First, like this picture.

Namenode enters into safemode when there is shortage of memory. As a result the HDFS becomes readable only. That means one can not create any additional directory or file in the HDFS. To come out of the safemode, the following command is used:

hadoop dfsadmin -safemode leave

If you are using cloudera manager:

go to >>Actions>>Leave Safemode

But it doesn't always solve the problem. The complete solution lies in making some space in the memory. Use the following command to check your memory usage.

free -m

If you are using cloudera, you can also check if the HDFS is showing some signs of bad health. It probably must be showing some memory issue related to the namenode. Allot more memory by following the options available. I am not sure what commands to use for the same if you are not using cloudera manager but there must be a way. Hope it helps! :)

None of these ideas helped my project using MVC 5.2.2.

• System.web.Http 5.2.2 was already installed
• Deleting the Packages folder and completely re-downloading all NuGet libraries did nothing
• Web.config already had a dependentAssembly entry for System.Web.Http

Forcing a reinstall corrected the problem. From the NuGet package manager console:

update-Package -reinstall Microsoft.AspNet.WebApi.WebHost

To change color of selected ViewCell, there is a simple process without using custom renderer. Make Tapped event of your ViewCell as below

<ListView.ItemTemplate>
    <DataTemplate>
        <ViewCell Tapped="ViewCell_Tapped">            
        <Label Text="{Binding StudentName}" TextColor="Black" />
        </ViewCell>
    </DataTemplate>
</ListView.ItemTemplate>

In your ContentPage or .cs file, implement the event

private void ViewCell_Tapped(object sender, System.EventArgs e)
{
    if(lastCell!=null)
    lastCell.View.BackgroundColor = Color.Transparent;
    var viewCell = (ViewCell)sender;
    if (viewCell.View != null)
    {
        viewCell.View.BackgroundColor = Color.Red;
        lastCell = viewCell;
    }
} 

Declare lastCell at the top of your ContentPage like this ViewCell lastCell;

Try this: TO_DATE('2011-07-28T23:54:14Z', 'YYYY-MM-DD"T"HH24:MI:SS"Z"')

Note that the native Array.forEach method is now widely supported.

This article by Andre Staltz is the best and clearest explanation I've seen so far.

Some quotes from the article:

Reactive programming is programming with asynchronous data streams.

On top of that, you are given an amazing toolbox of functions to combine, create and filter any of those streams.

Here's an example of the fantastic diagrams that are a part of the article:

If you get net::ERR_CONTENT_DECODING_FAILED in the console then you are using gzip in your .htaccess file but gzip encoding is Off.

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

PHP extensions for Ubuntu 20.04 LTS (Focal Fossa)

Bit less elegant but can also do:

Please Try This one:

Try Adding input Css like this:

 -webkit-appearance: none;
       border-radius: 0;

Short answer: You can't.

You will have to use border-image property and a few images.

Regardless of how do you index the pushbacks your vector contains 10 elements indexed from 0 (0, 1, ..., 9). So in your second loop v[j] is invalid, when j is 10.

This will fix the error:

for(int j = 9;j >= 0;--j)
{
    cout << v[j];
}

In general it's better to think about indexes as 0 based, so I suggest you change also your first loop to this:

for(int i = 0;i < 10;++i)
{
    v.push_back(i);
}

Also, to access the elements of a container, the idiomatic approach is to use iterators (in this case: a reverse iterator):

for (vector<int>::reverse_iterator i = v.rbegin(); i != v.rend(); ++i)
{
    std::cout << *i << std::endl;
}

The alternative for explode in php is split.

The first parameter is the delimiter, the second parameter the maximum number splits. The parts are returned without the delimiter present (except possibly the last part). When the delimiter is None, all whitespace is matched. This is the default.

>>> "Rajasekar SP".split()
['Rajasekar', 'SP']

>>> "Rajasekar SP".split('a',2)
['R','j','sekar SP']

You have install nodeJs on your system in order to execute npm commands. Once npm is properly working you can visit bower.io. There you will find complete documentation on this topic. You will find a command $ npm install bower. this will install bower on your machine. After installing bower you can install Bootstrap easily.

Here is a video tutorial on that

If you're using a variable when searching in a string, mysql_real_escape_string() is good for you. Just my suggestion:

$char = "and way's 'hihi'";
$myvar = mysql_real_escape_string($char);

select * from tablename where fields like "%string $myvar  %";

Shortest version without form, min or external JavaScript.

<input type="range" value="0" max="10" oninput="num.value = this.value">
<output id="num">0</output>

Explanation

If you wanna retrieve the value from the output you commonly use an id that can be linked from the oninput instead of using this.nextElementSibling.value (we take advantage of something that we are already using)

Compare the example above with this valid but a little more complex and long answer:

<input id="num" type="range" value="0" max="100" oninput="this.nextElementSibling.value = this.value">
<output>0</output>

With the shortest answer:

• We avoid the use of this, something weird in JS for newcomers
• We avoid new concept about connecting siblings in the DOM
• We avoid too much attributes in the input placing the id in the output

Notes

• In both examples we don't need to add the min value when equal to 0
• Removing JavaScript’s this keyword makes it a better language

Today I faced the same issue where my database was changed from Multi User to Single User mode and this was eventually stopping me to publish database.

In order to fix this issue, I had to close all Visual Studio instances and run the below command in Sql Server query window -

USE [Your_Database_Name]; ALTER DATABASE [Your_Database_Name] SET MULTI_USER GO

This command has changed the DB from Single user to Multi User and afterwards, I was successfully able to publish.

Use Singular and take advantage of the English convention seen in e.g. "Business Directory".

Lots of things read this way: "Book Case", "Dog Pack", "Art Gallery", "Film Festival", "Car Lot", etc.

This conveniently matches the url path left to right. Item type on the left. Set type on the right.

Does GET /users really ever fetch a set of users? Not usually. It fetches a set of stubs containing a key and perhaps a username. So it's not really /users anyway. It's an index of users, or a "user index" if you will. Why not call it that? It's a /user/index. Since we've named the set type, we can have multiple types showing different projections of a user without resorting to query parameters e.g. user/phone-list or /user/mailing-list.

And what about User 300? It's still /user/300.

GET /user/index
GET /user/{id}

POST /user
PUT /user/{id}

DELETE /user/{id}

In closing, HTTP can only ever have a single response to a single request. A path is always referring to a singular something.

Sometimes NaNs or null values in data will generate this error with Numpy. If you are ingesting data from say, a CSV file or something like that, and then operating on the data using numpy arrays, the problem could have originated with your data ingest. You could try feeding your code a small set of data with known values, and see if you get the same result.

Use the SingleOrDefault() instead of FirstOrDefault().

This CSS also shows a fixed height HTML table. It sets the height of the HTML tbody to 400 pixels and the HTML tbody scrolls when the it is larger, retaining the HTML thead as a non-scrolling element.

In addition, each th cell in the heading and each td cell the body should be styled for the desired fixed width.

#the-table {
  display: block;
  background: white; /* optional */
}

#the-table thead {
  text-align: left; /* optional */
}

#the-table tbody {
  display: block;
  max-height: 400px;
  overflow-y: scroll;
}

I think you probably want to use a token list for this purpose: to set up the token list \newtoks\packagename to assign the name: \packagename={New Name for the package} to put the name into your output: \the\packagename.

You could use FileAPI, but it's pretty much unsupported.

It worked for me when I selected 'Use Host GPU' option under 'Emulation Options:'.

You can find the option under Edit window of the virtual device.

The solution I found was to use the New-Object cmdlet to initialize an array of the proper size.

$array = new-object object[] 5 
for($i=0; $i -lt $array.Length;$i++)
{
    $array[$i] = $FALSE
}

It's working for me:

File file = path.toFile();
String mimeType = Files.probeContentType(path);     

DiskFileItem fileItem = new DiskFileItem("file", mimeType, false, file.getName(), (int) file.length(),
            file.getParentFile());
fileItem.getOutputStream();
MultipartFile multipartFile = new CommonsMultipartFile(fileItem);

The other answer is very detailed and addresses the bulk of the questions raised by the OP.

To elaborate, and specifically to address the OP's question of "How does OAuth 2 protect against things like replay attacks using the Security Token?", there are two additional protections in the official recommendations for implementing OAuth 2:

1) Tokens will usually have a short expiration period (http://tools.ietf.org/html/rfc6819#section-5.1.5.3):

A short expiration time for tokens is a means of protection against the following threats:

• replay...

2) When the token is used by Site A, the recommendation is that it will be presented not as URL parameters but in the Authorization request header field (http://tools.ietf.org/html/rfc6750):

Clients SHOULD make authenticated requests with a bearer token using the "Authorization" request header field with the "Bearer" HTTP authorization scheme. ...

The "application/x-www-form-urlencoded" method SHOULD NOT be used except in application contexts where participating browsers do not have access to the "Authorization" request header field. ...

URI Query Parameter... is included to document current use; its use is not recommended, due to its security deficiencies

|| and && bind with the precedence that you expect from boolean operators in programming languages (&& is very strong, || is slightly less strong).

and and or have lower precedence.

For example, unlike ||, or has lower precedence than =:

> a = false || true
 => true 
> a
 => true 
> a = false or true
 => true 
> a
 => false

Likewise, unlike &&, and also has lower precedence than =:

> a = true && false
 => false 
> a
 => false 
> a = true and false
 => false 
> a
 => true 

What's more, unlike && and ||, and and or bind with equal precedence:

> !puts(1) || !puts(2) && !puts(3)
1
 => true
> !puts(1) or !puts(2) and !puts(3)
1
3
 => true 
> !puts(1) or (!puts(2) and !puts(3))
1
 => true

The weakly-binding and and or may be useful for control-flow purposes: see http://devblog.avdi.org/2010/08/02/using-and-and-or-in-ruby/ .

I have:

1. Right-click on project with issue -> Unload Project
2. Right-click on project and choose Edit *.csproj

3. Copy-paste the configuration from existing configuration which works with specific name and targeting platform (I had Release | x64):

   <PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|x64'">
     <OutputPath>bin\x64\Release\</OutputPath>
     <DefineConstants>TRACE</DefineConstants>
     <Optimize>true</Optimize>
     <DebugType>pdbonly</DebugType>
     <PlatformTarget>x64</PlatformTarget>
     <ErrorReport>prompt</ErrorReport>
     <CodeAnalysisRuleSet>MinimumRecommendedRules.ruleset</CodeAnalysisRuleSet>
     <Prefer32Bit>true</Prefer32Bit>
   </PropertyGroup>
   

4. Right-click project -> Reload Project
5. Rebuild project/solution

Load data infile query is much better option but some servers like godaddy restrict this option on shared hosting so , only two options left then one is insert record on every iteration or batch insert , but batch insert has its limitaion of characters if your query exceeds this number of characters set in mysql then your query will crash , So I suggest insert data in chunks withs batch insert , this will minimize number of connections established with database.best of luck guys

use like this your inline css

<td width="178" rowspan="3" valign="top" 
align="right" background="images/left.jpg" 
style="background-repeat:background-position: right top;">
</td>

Generic solution that doesn't require a GUI like jconsole (doesn't work on remote terminals), ps works for non-java processes, doesn't require a JVM installed.

ps -o nlwp <pid>

if you want to upgrade only a single column of a table row then you can use as following:

$this->db->set('column_header', $value); //value that used to update column  
$this->db->where('column_id', $column_id_value); //which row want to upgrade  
$this->db->update('table_name');  //table name

Are you sure you can't alter the HTML in the popup window?

If you can, add a <script> tag at the end of the popup's HTML, and call window.print() inside it. Then it won't be called until the HTML has loaded.

This is what I do on mine

$(document).ready(function() {
  if ($('#userForm').valid()) {
    var formData = $("#userForm").serializeArray();
    $.ajax({
      url: 'http://www.example.com/user/' + $('#Id').val() + '?callback=?',
      type: "GET",
      data: formData,
      dataType: "jsonp",
      jsonpCallback: "localJsonpCallback"
    });
  });

function localJsonpCallback(json) {
  if (!json.Error) {
    $('#resultForm').submit();
  } else {
    $('#loading').hide();
    $('#userForm').show();
    alert(json.Message);
  }
}

The Facebook "Graph API Rate Limiting" docs says that an error with code #4 is an app level rate limit, which is different than user level rate limits. Although it doesn't give any exact numbers, it describes their app level rate-limit as:

This rate limiting is applied globally at the app level. Ads api calls are excluded.

• Rate limiting happens real time on sliding window for past one hour.
• Stats is collected for number of calls and queries made, cpu time spent, memory used for each app.
• There is a limit for each resource multiplied by monthly active users of a given app.
• When the app uses more than its allowed resources the error is thrown.
• Error, Code: 4, Message: Application request limit reached

The docs also give recommendations for avoiding the rate limits. For app level limits, they are:

Recommendations:

• Verify the error code (4) to confirm the throttling type.
• Do not make burst of calls, spread out the calls throughout the day.
• Do smart fetching of data (important data, non duplicated data, etc).
  • Real-time insights, make sure API calls are structured in a way that you can read insights for as many as Page posts as possible, with minimum number of requests.
  • Don't fetch users feed twice (in the case that two App users have a specific friend in common)
  • Don't fetch all user's friends feed in a row if the number of friends is more than 250. Separate the fetches over different days. As an option, fetch first the app user's news feed (me/home) in order to detect which friends are more important to the App user. Then, fetch those friends feeds first.
• Consider to limit/filter the requests by using the following parameters: "since", "until", "limit"
• For page related calls use realtime updates to subscribe to changes in data.
• Field expansion allows ton "join" multiple graph queries into a single call.
• Etags to check if the data querying has changed since the last check.
• For page management developers who does not have massive user base, have the admins of the page to accept the app to increase the number of users.

Finally, the docs give the following informational tips:

• Batching calls will not reduce the number of api calls.
• Making parallel calls will not reduce the number of api calls.

Using Jquery you could do something like this:

$(document).ready(function() {
    if ($("img").attr("src") != null)
    {
       if ($("img").attr("src").toString() == "")
       {
            $("img").attr("src", "images/default.jpg");
       }
    }
    else
    {
        $("img").attr("src", "images/default.jpg");
    }
});

If you have no Medium security level, then you should add your application to the Exception Site List (Java Control Panel ? Security tab).

1. Open your applet in a browser and copy the contents of your address bar.

2. Go to Control Panel ? Java Control Panel ? Security tab and press the Edit Site List... button.

3. Press the Add button, insert your path and press Enter.

4. Press Continue on the security warning that appears.

5. Open the applet again and don't forget to press Run on the pop-up window.

The top answer of the question Anders Lindahl refers to an xsd file.

Personally I found this xsd file also very useful (I don't remember how I found that one). It looks a bit less intimidating, and as far as I used it, all the elements and attributes seem to be recognized by Jenkins (v1.451)

One thing though: when adding multiple <failure ... elements, only one was retained in Jenkins. When creating the xml file, I now concatenate all the failures in one.

Update 2016-11 The link is broken now. A better alternative is this page from cubic.org: JUnit XML reporting file format, where a nice effort has been taken to provide a sensible documented example. Example and xsd are copied below, but their page looks waay nicer.

You can use this

@echo off
for /F %%i in ('dir /b "c:\test directory\*.*"') do (
   echo Folder is NON empty
   goto :EOF
)
echo Folder is empty or does not exist

Taken from here.

That should do what you need.

As mentioned in a comment by @user566245 :

this is correct in principle, but individual mileage may vary. For example certain elements like textarea by default have a border, applying this reset will render those textarea's border less.

JAVASCRIPT ?

Nobody thought about other than css to reset css? Yes?

There is that snip fully relevant : https://stackoverflow.com/a/14791113/845310

getElementsByTagName("*") will return all elements from DOM. Then you may set styles for each element in the collection:

answered Feb 9 '13 at 20:15 by VisioN

var allElements = document.getElementsByTagName("*");
for (var i = 0, len = allElements.length; i < len; i++) {
    var element = allElements[i];
    // element.style.border = ...
}

With all this said; i don't think a css reset is something feasable unless we end up with only one web browser .. if the 'default' is set by browser in the end.

I assumed openjdk8 would work with tomcat8 but I had to remove it and keep openjdk7 only, this fixed the issue in my case. I really don't know why or if there is something else I could have done.

The casting of a string (i.e. "5/1/2009") to datetime is certainly more legible but we found code a while back that would return the first of the month...

DECLARE @Date DATETIME
//...
SELECT DATEADD(mm, DATEDIFF(mm,0,@Date), 0)

@Egidius, when creating an XMLHttpRequest, you should use

var xhr = new XMLHttpRequest({mozSystem: true});

What is mozSystem?

mozSystem Boolean: Setting this flag to true allows making cross-site connections without requiring the server to opt-in using CORS. Requires setting mozAnon: true, i.e. this can't be combined with sending cookies or other user credentials. This only works in privileged (reviewed) apps; it does not work on arbitrary webpages loaded in Firefox.

Changes to your Manifest

On your manifest, do not forget to include this line on your permissions:

"permissions": {
       "systemXHR" : {},
}

The following site uses System.Management to accomplish the same is a very sleek way in a console application

Implemented in JavaScript (ES6):

/**

    * @param {Object} input - The input parameters
    * @param {number} input.radius - The circle's radius
    * @param {number} input.angle - The angle in degrees
    * @param {number} input.cx - The circle's origin x
    * @param {number} input.cy - The circle's origin y
    * @returns {Array[number,number]} The calculated x and y
*/
function pointsOnCircle({ radius, angle, cx, cy }){

    angle = angle * ( Math.PI / 180 ); // Convert from Degrees to Radians
    const x = cx + radius * Math.sin(angle);
    const y = cy + radius * Math.cos(angle);
    return [ x, y ];

}

Usage:

const [ x, y ] = pointsOnCircle({ radius: 100, angle: 180, cx: 150, cy: 150 });
console.log( x, y );

Codepen

/**

You dont need absolute positioning Use

p {
 text-align: center;
line-height: 100px;

}

And adjust at will...

If text exceeds width and goes more than one line

In that case the adjust you can do is to include the display property in your rules as follows;

(I added a background for a better view of the example)

div
{
  width:300px;
  height:100px;  
  display: table; 
  background:#ccddcc;  
}


p {
  text-align:center; 
  vertical-align: middle;
  display: table-cell;   
}

Using Android's built in method

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

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

More details

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

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

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

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

Example

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

another simple way to pass object using a bundle:

• in the class object, create a static list or another data structure with a key
• when you create the object, put it in the list/data structure with the key (es. the long timestamp when the object is created)
• create the method static getObject(long key) to get the object from the list
• in the bundle pass the key, so you can get the object later from another point in the code

But you can open the folder with the .SLN in to edit the code in the project, which will detect the .SLN to select the library that provides Intellisense.

@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.

.box {_x000D_
  width: 500px;_x000D_
  height: 100px;_x000D_
  border: solid 5px #000;_x000D_
  border-color: transparent transparent #000 transparent;_x000D_
  border-radius: 0 0 240px 50%/60px;_x000D_
}

<div class="box"></div>

ORDER BY alters the order in which items are returned.

GROUP BY will aggregate records by the specified columns which allows you to perform aggregation functions on non-grouped columns (such as SUM, COUNT, AVG, etc).

(using the same example as the guy above)

from matplotlib import pyplot
import numpy
a = numpy.arange(int(1e3))
fig = pyplot.Figure()
ax  = fig.add_subplot(1, 1, 1)
lines = ax.plot(a)

for i, line in enumerate(ax.lines):
    ax.lines.pop(i)
    line.remove()

Received this same error on SQL Server 2017 trying to link to Oracle 12c. We were able to use Oracle's SQL Developer to connect to the source database, but the linked server kept throwing the 7302 error.

In the end, we stopped all SQL Services, then re-installed the ODAC components. Started the SQL Services back up and voila!

To remove duplicates from a column

1. Sort the values in column A A->Z
2. Select column B

3. While column B is still selected, in the formula input box, enter

   =IF(TRIM(A1)=TRIM(A2),"",TRIM(A1))
   

4. While Column B is still selected, select Edit -> Fill -> Down (in newer versions, simply select cell B1 and pull down the outer box to expand all the way down in the column)

Note: if column B is on another sheet, you may do Sheet1!A1 and Sheet1!A2.

You can use cmd + ; for Mac or Ctrl + Alt + Shift + S for Windows/Linux to pull up the Project Structure dialog. In there, you can set the JDK location as well as the Android SDK location.

To get your JDK location, run /usr/libexec/java_home -v 1.7 in terminal. Send 1.7 for Java 7 or 1.8 for Java 8.

I have exactly the same issue with you. I have TortoiseSVN installed on my windows, I have also eclipse installed, in the eclipse, I have the subclipse 1.4 installed.

here is the issue I have proxy settings, I can open the repo through web browser, for some reason, I cannot open a repo through svn. I tried to change the proxy following the link below Eclipse Kepler not connecting to internet via proxy. It doesn't work.

Finally I found out a solution

You have to change the proxy setting in TortoiseSVN. After I enable the proxy setting the same with my browser. The issue is gone.

here is the link of how to enable proxy setting in TortoiseSVN https://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-settings.html Seach "Network Settings" on the page above

Environment variable (can access anywhere/ dynamic object) is a type of variable. They are of 2 types system environment variables and user environment variables.

System variables having a predefined type and structure. That are used for system function. Values that produced by the system are stored in the system variable. They generally indicated by using capital letters Example: HOME,PATH,USER

User environment variables are the variables that determined by the user,and are represented by using small letters.

the core functions are getBytes(String charset) and new String(byte[] data). you can use these functions to do UTF-8 decoding.

UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String() is the byte array, which calling is equal to new String(bytes, "UTF-8")

Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.

The decoding sentence should be

String decoded = new String(encoded.getBytes("ISO-8859-1"));

To add on to Ken's answer, this handles commas and spaces and parentheses

--Handles parentheses, commas, spaces, hyphens..

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

I like this approach. It feels simple and not magical and supports all iterable types and doesn't require imports.

def chunk_iter(iterable, chunk_size):
it = iter(iterable)
while True:
    chunk = tuple(next(it) for _ in range(chunk_size))
    if not chunk:
        break
    yield chunk

I know this is an old question, already answered, but here is my take on this; I refactored the suspension of updates into an IDisposable - that way I can enclose the statements I want to run in a using statement.

class SuspendDrawingUpdate : IDisposable
{
    private const int WM_SETREDRAW = 0x000B;
    private readonly Control _control;
    private readonly NativeWindow _window;

    public SuspendDrawingUpdate(Control control)
    {
        _control = control;

        var msgSuspendUpdate = Message.Create(_control.Handle, WM_SETREDRAW, IntPtr.Zero, IntPtr.Zero);

        _window = NativeWindow.FromHandle(_control.Handle);
        _window.DefWndProc(ref msgSuspendUpdate);
    }

    public void Dispose()
    {
        var wparam = new IntPtr(1);  // Create a C "true" boolean as an IntPtr
        var msgResumeUpdate = Message.Create(_control.Handle, WM_SETREDRAW, wparam, IntPtr.Zero);

        _window.DefWndProc(ref msgResumeUpdate);

        _control.Invalidate();
    }
}

this will sort it for you

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button but1=(Button)findViewById(R.id.button1);

    but1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent int1= new Intent(MainActivity.this,xxactivity.class);
            startActivity(int1);
        }
    });
}

You just need to amend the xxactivity to the name of your second activity

The OpenCV Android SDK has an example gradle.build file with helpful comments: https://github.com/opencv/opencv/blob/master/modules/java/android_sdk/build.gradle.in

//
//   Import module: Menu -> "File" -> "New" -> "Module" -> "Import Gradle project":

These answers were helpful in solving a similar issue while trying to define a named range with Workbook scope. The "ah-HA!" for me is to use the Names Collection which is relative to the whole Workbook! This may be restating the obvious to many, but it wasn't clearly stated in my research, so I share for other's with similar questions.

' Local / Worksheet only scope
Worksheets("Sheet2").Names.Add Name:="a_test_rng1", RefersTo:=Range("A1:A4")

' Global / Workbook scope
ThisWorkbook.Names.Add Name:="a_test_rng2", RefersTo:=Range("B1:b4") 

If you look at your list of names when Sheet2 is active, both ranges are there, but switch to any other sheet, and "a_test_rng1" is not present.

Now I can happily generate a named range in my code with what ever scope I deem appropriate. No need mess around with the name manager or a plug in.

Aside, the name manager in Excel Mac 2011 is a mess, but I did discover that while there are no column labels to tell you what you're looking at while viewing your list of named ranges, if there is a sheet listed beside the name, that name is scoped to worksheet / local. See screenshot attached.

Full credit to this article for putting together the pieces.

convert Collection into string as comma seperated in Java 8

listOfString object contains ["A","B","C" ,"D"] elements-

listOfString.stream().map(ele->"'"+ele+"'").collect(Collectors.joining(","))

Output is :- 'A','B','C','D'

And Convert Strings Array to List in Java 8

    String string[] ={"A","B","C","D"};
    List<String> listOfString = Stream.of(string).collect(Collectors.toList());

In jQuery just use an attribute selector like

$('input[name="locationthemes"]:checked');

to select all checked inputs with name "locationthemes"

console.log($('input[name="locationthemes"]:checked').serialize());

//or

$('input[name="locationthemes"]:checked').each(function() {
   console.log(this.value);
});

Demo

In VanillaJS

[].forEach.call(document.querySelectorAll('input[name="locationthemes"]:checked'), function(cb) {
   console.log(cb.value); 
});

Demo

In ES6/spread operator

[...document.querySelectorAll('input[name="locationthemes"]:checked')]
   .forEach((cb) => console.log(cb.value));

Demo

console.log( Object.keys( {'a':1,'b':2} ) );

string startTime = "7:00 AM";
string endTime = "2:00 PM";

TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));

Console.WriteLine(duration);
Console.ReadKey();

Will output: 07:00:00.

It also works if the user input military time:

string startTime = "7:00";
string endTime = "14:00";

TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));

Console.WriteLine(duration);
Console.ReadKey();

Outputs: 07:00:00.

To change the format: duration.ToString(@"hh\:mm")

Addendum:

Over the years it has somewhat bothered me that this is the most popular answer I have ever given; the original answer never actually explained why the OP's code didn't work despite the fact that it is perfectly valid. The only reason it gets so many votes is because the post comes up on Google when people search for a combination of the terms "C#", "timespan", and "between".

JsonConvert.SerializeObject(ObjectName, new JsonSerializerSettings(){ PreserveReferencesHandling = PreserveReferencesHandling.Objects, Formatting = Formatting.Indented });

You also can get it from any ContainerAware (f.i. Controller) class from the request service:

• If you are using apache as a webserver (I suppose for other webservers the solution would be similar) and are using virtualhosting (your urls look like this - localhost/app.php then you can use:

  $container->get('request')->server->get('DOCUMENT_ROOT');
  // in controller:
  $this->getRequest()->server->get('DOCUMENT_ROOT');
  

• Else (your urls look like this - localhost/path/to/Symfony/web/app.php:

  $container->get('request')->getBasePath();
  // in controller:
  $this->getRequest()->getBasePath();
  

You can achieve spacing between columns using the col-xs-* classes,within in a col-xs-* div coded below. The spacing is consistent so that all of your columns line up correctly. To get even spacing and column size I would do the following:

<div class="container">
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
</div>

## you can use request module and promise in express to make any request ##

Another possible way to do that:

from django.core.files import File

with open('path_to_file', 'r') as f:   # use 'rb' mode for python3
    data = File(f)
    model.image.save('filename', data, True)

One of the goals of compilers is to rule out classes of errors. Some unreachable code is there by accident, it's nice that javac rules out that class of error at compile time.

For every rule that catches erroneous code, someone will want the compiler to accept it because they know what they're doing. That's the penalty of compiler checking, and getting the balance right is one of the tricker points of language design. Even with the strictest checking there's still an infinite number of programs that can be written, so things can't be that bad.

If you try to run 32-bit applications on IIS 7 (and/or 64-bit OS machine), you will get the same error. So, from the IIS 7, right click on the applications' application pool and go to "advanced settings" and change "Enable 32-Bit Applications" to "TRUE".

Restart your website and it should work.

Microsoft Core Library, ie they are at the heart of everything.

There is a more "massaged" explanation you may prefer:

"When Microsoft first started working on the .NET Framework, MSCorLib.dll was an acronym for Microsoft Common Object Runtime Library. Once ECMA started to standardize the CLR and parts of the FCL, MSCorLib.dll officially became the acronym for Multilanguage Standard Common Object Runtime Library."

From http://weblogs.asp.net/mreynolds/archive/2004/01/31/65551.aspx

Around 1999, to my personal memory, .Net was known as "COOL", so I am a little suspicious of this derivation. I never heard it called "COR", which is a silly-sounding name to a native English speaker.

Just try with:

var check = moment(n.entry.date_entered, 'YYYY/MM/DD');

var month = check.format('M');
var day   = check.format('D');
var year  = check.format('YYYY');

Why all the other answers use slideUp is just beyond me. As I'm using the fade and in classes to have the alert fade away when closed (or after timeout), I don't want it to "slide up" and conflict with that.

Besides the slideUp method didn't even work. The alert itself didn't show at all. Here's what worked perfectly for me:

$(document).ready(function() {
    // show the alert
    setTimeout(function() {
        $(".alert").alert('close');
    }, 2000);
});

Here is a simple way to iterate through your custom Enum object

For Each enumValue As Integer In [Enum].GetValues(GetType(MyEnum))

EntryStream.of(countByType).sortedBy(e -> e.getValue()).keys().toList();

Being the author of the response that you highlight in your question, and admittedly coming to this one a bit late, I'd have to say that among the many reasons that have been listed, the productivity of a professional developer is one of the most highly-regarded skills.

By productivity, I mean the ability to do your job efficiently with the best-possible results. IDEs enable this on many levels. I'm not an Emacs expert, but I doubt that it lacks any of the features of the major IDEs.

Design, documentation, tracking, developing, building, analyzing, deploying, and maintenance, key stepping stones in an enterprise application, can all be done within an IDE.

Why you wouldn't use something so powerful if you have the choice?

As an experiment, commit yourself to use an IDE for, say, 30 days, and see how you feel. I would love to read your thoughts on the experience.

Ref: zip built-in function

zip() in conjunction with the * operator can be used to unzip a list

unzip_lst = zip(*mylist)
for i in unzip_lst:
    for j in i:
        print j

It seems to me that all other answers here (so far) fail to address the race-condition that occurs with their proposed solutions.

Any code where you first check for the files existence, and then, a few lines later in your program, you create it, runs the risk of the file being created while you weren't looking and causing you problems (or you causing the owner of "that other file" problems).

If you want to avoid this sort of thing, I would suggest something like the following (untested):

import os

def open_if_not_exists(filename):
    try:
        fd = os.open(filename, os.O_CREAT | os.O_EXCL | os.O_WRONLY)
    except OSError, e:
        if e.errno == 17:
            print e
            return None
        else:
            raise
    else:
        return os.fdopen(fd, 'w')

This should open your file for writing if it doesn't exist already, and return a file-object. If it does exists, it will print "Ooops" and return None (untested, and based solely on reading the python documentation, so might not be 100% correct).

There are two types of quotes in MySQL:

1. ' for enclosing string literals
2. ` for enclosing identifiers such as table and column names

And then there is " which is a special case. It could be used for one of above-mentioned purposes at a time depending on MySQL server's sql_mode:

1. By default the " character can be used to enclose string literals just like '
2. In ANSI_QUOTES mode the " character can be used to enclose identifiers just like `

The following query will produce different results (or errors) depending on SQL mode:

SELECT "column" FROM table WHERE foo = "bar"

ANSI_QUOTES disabled

The query will select the string literal "column" where column foo is equal to string "bar"

ANSI_QUOTES enabled

The query will select the column column where column foo is equal to column bar

When to use what

• I suggest that you avoid using " so that your code becomes independent of SQL modes
• Always quote identifiers since it is a good practice (quite a few questions on SO discuss this)

What you are missing, as idljarn already mentioned in a comment is that if you are overriding a function from a base class, then you cannot possibly mark it as non-virtual:

struct base {
   virtual void f();
};
struct derived : base {
   void f() final;       // virtual as it overrides base::f
};
struct mostderived : derived {
   //void f();           // error: cannot override!
};

Subtract from another date object

Better to first compress catalog on remote server:

tar czfP backup.tar.gz /path/to/catalog

Secondly, download from remote:

scp [email protected]:/path/to/backup.tar.gz .

At the end, extract the files:

tar -xzvf backup.tar.gz

In fact, it is very easy.

composer update

will do all this for you, but it will also update the other packages.

To remove a package without updating the others, specifiy that package in the command, for instance:

composer update monolog/monolog

will remove the monolog/monolog package.

Nevertheless, there may remain some empty folders or files that cannot be removed automatically, and that have to be removed manually.

This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.

Ensures that the object is displayed (or should be) only to readers and similar devices. It give more sense in context with other element with attribute aria-hidden="true".

<div class="alert alert-danger" role="alert">
  <span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>
  <span class="sr-only">Error:</span>
  Enter a valid email address
</div>

Glyphicon will be displayed on all other devices, word Error: on text readers.

In addition to what Tichodroma said, you might end up using this syntax:

outputString=$(python myPythonScript arg1 arg2 arg3)

Signed variables use one bit to flag whether they are positive or negative. Unsigned variables don't have this bit, so they can store larger numbers in the same space, but only nonnegative numbers, e.g. 0 and higher.

Yes ..it is possible using INSERT ON DUPLICATE KEY UPDATE sql statement.. syntax: INSERT INTO table_name (a,b,c) VALUES (1,2,3),(4,5,6) ON DUPLICATE KEY UPDATE a=VALUES(a),b=VALUES(b),c=VALUES(c)

Before I show you how to reload / refresh model data from the server programmatically? I have to explain for you the concept of Data Binding. This is an extremely powerful concept that will truly revolutionize the way you develop. So may be you have to read about this concept from this link or this seconde link in order to unterstand how AngularjS work.

now I'll show you a sample example that exaplain how can you update your model from server.

HTML Code:

<div ng-controller="PersonListCtrl">
    <ul>
        <li ng-repeat="person in persons">
            Name: {{person.name}}, Age {{person.age}}
        </li>
    </ul>
   <button ng-click="updateData()">Refresh Data</button>
</div>

So our controller named: PersonListCtrl and our Model named: persons. go to your Controller js in order to develop the function named: updateData() that will be invoked when we are need to update and refresh our Model persons.

Javascript Code:

app.controller('adsController', function($log,$scope,...){

.....

$scope.updateData = function(){
$http.get('/persons').success(function(data) {
       $scope.persons = data;// Update Model-- Line X
     });
}

});

Now I explain for you how it work: when user click on button Refresh Data, the server will call to function updateData() and inside this function we will invoke our web service by the function $http.get() and when we have the result from our ws we will affect it to our model (Line X).Dice that affects the results for our model, our View of this list will be changed with new Data.

To understand methods you must first think in terms of object oriented programming: Let's take a car as a a class. All cars have things in common and things that make them unique, for example all cars have 4 wheels, doors, a steering wheel.... but Your individual car (Lets call it, my_toyota) is red, goes from 0-60 in 5.6s Further the car is currently located at my house, the doors are locked, the trunk is empty... All those are properties of the instance of my_toyota. your_honda might be on the road, trunk full of groceries ...

However there are things you can do with the car. You can drive it, you can open the door, you can load it. Those things you can do with a car are methods of the car, and they change a properties of the specific instance.

as pseudo code you would do:

my_toyota.drive(shop)

to change the location from my home to the shop or

my_toyota.load([milk, butter, bread]

by this the trunk is now loaded with [milk, butter, bread].

As such a method is practically a function that acts as part of the object:

class Car(vehicle)
    n_wheels = 4

    load(self, stuff):
    '''this is a method, to load stuff into the trunk of the car'''
        self.open_trunk
        self.trunk.append(stuff)
        self.close_trunk

the code then would be:

my_toyota = Car(red)
my_shopping = [milk, butter, bread]
my_toyota.load(my_shopping)

If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.

First of all, where you're going wrong is the offset.

It should look more like this...

set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%

If the date was Tue 12/02/2013 then it would display it as 2013/02/12.

To remove the slashes, the code would look more like

set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%

which would output 20130212

And a hint for doing it in the future, if mydate equals something like %date:~10,4%%date:~7,2% or the like, you probably forgot a tilde (~).

By using the constraint definition on table creation, you can specify one or multiple constraints that span multiple columns. The syntax, simplified from technet's documentation, is in the form of:

CONSTRAINT constraint_name UNIQUE [ CLUSTERED | NONCLUSTERED ] 
(
    column [ ASC | DESC ] [ ,...n ]
)

Therefore, the resuting table definition would be:

CREATE TABLE [dbo].[user](
    [userID] [int] IDENTITY(1,1) NOT NULL,
    [fcode] [int] NULL,
    [scode] [int] NULL,
    [dcode] [int] NULL,
    [name] [nvarchar](50) NULL,
    [address] [nvarchar](50) NULL,
    CONSTRAINT [PK_user_1] PRIMARY KEY CLUSTERED 
    (
        [userID] ASC
    ),
    CONSTRAINT [UQ_codes] UNIQUE NONCLUSTERED
    (
        [fcode], [scode], [dcode]
    )
) ON [PRIMARY]

Ken Clark's answer didn't work in my case. It might not work in yours either. If not, try this:

SELECT * 
from table T

INNER JOIN
  (
  select id, MIN(point) MinPoint
  from table T
  group by AccountId
  ) NewT on T.id = NewT.id and T.point = NewT.MinPoint

ORDER BY game desc

I have made a small demo of NumberPicker. This may not be perfect but you can use and modify the same.

public class MainActivity extends Activity implements NumberPicker.OnValueChangeListener
{
    private static TextView tv;
    static Dialog d ;
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv = (TextView) findViewById(R.id.textView1);
        Button b = (Button) findViewById(R.id.button11);
         b.setOnClickListener(new OnClickListener()
         {

            @Override
            public void onClick(View v) {
                 show();
            }
            });

I had this issue and I solved it by creating a directory in mysite folder to hold my db.sqlite3 file. so I did /home/user/src/mysite/database/db.sqlite3. In my django setting file I change my

 DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.sqlite3',
    'NAME': "/home/user/src/mysite/database/db.sqlite3" ,
}}

I did this to make Django aware that I am storing my database in a sub directory of the base directory, which mysite in my case. Now you need to grant the permission to apache to be able read write the database.

chown user:www-data database/db.sqlite3
chown user:www-data database 
chmod 755 database
 chmod 755 database/db.sqlite3

This solved my problem. Here is a list of the different permissions. You can use choose the one that fits you but avoid 777 and 666

-rw------- (600) -- Only the user has read and write permissions.

-rw-r--r-- (644) -- Only user has read and write permissions; the group and others can read only.

-rwx------ (700) -- Only the user has read, write and execute permissions.

-rwxr-xr-x (755) -- The user has read, write and execute permissions; the group and others can only read and execute.

-rwx--x--x (711) -- The user has read, write and execute permissions; the group and others can only execute.

-rw-rw-rw- (666) -- Everyone can read and write to the file. Bad idea.

-rwxrwxrwx (777) -- Everyone can read, write and execute. Another bad idea.

Here are a couple common settings for directories:

drwx------ (700) -- Only the user can read, write in this directory.

drwxr-xr-x (755) -- Everyone can read the directory, but its contents can only be changed by the user.

For some reason, a question about GET requests was merged with this one, so I'll respond to it here.

This simple function will asynchronously get an HTTP status reply from a CORS-enabled page. If you run it, you'll see that only a page with the proper headers returns a 200 status if accessed via XMLHttpRequest -- whether GET or POST is used. Nothing can be done on the client side to get around this except possibly using JSONP if you just need a json object.

The following can be easily modified to get the data held in the xmlHttpRequestObject object:

function checkCorsSource(source) {_x000D_
  var xmlHttpRequestObject;_x000D_
  if (window.XMLHttpRequest) {_x000D_
    xmlHttpRequestObject = new XMLHttpRequest();_x000D_
    if (xmlHttpRequestObject != null) {_x000D_
      var sUrl = "";_x000D_
      if (source == "google") {_x000D_
        var sUrl = "https://www.google.com";_x000D_
      } else {_x000D_
        var sUrl = "https://httpbin.org/get";_x000D_
      }_x000D_
      document.getElementById("txt1").innerHTML = "Request Sent...";_x000D_
      xmlHttpRequestObject.open("GET", sUrl, true);_x000D_
      xmlHttpRequestObject.onreadystatechange = function() {_x000D_
        if (xmlHttpRequestObject.readyState == 4 && xmlHttpRequestObject.status == 200) {_x000D_
          document.getElementById("txt1").innerHTML = "200 Response received!";_x000D_
        } else {_x000D_
          document.getElementById("txt1").innerHTML = "200 Response failed!";_x000D_
        }_x000D_
      }_x000D_
      xmlHttpRequestObject.send();_x000D_
    } else {_x000D_
      window.alert("Error creating XmlHttpRequest object. Client is not CORS enabled");_x000D_
    }_x000D_
  }_x000D_
}

It is the solution that I found for this problem:

//If IE

inputElement.writeAttribute("unselectable", "on");

//Other browsers

inputElement.writeAttribute("disabled", "disabled");

By using this trick, you can add style sheet to your input element that works in IE and other browsers on your not-editable input box.

I have no very simple solution, but here are the main steps for the real algorithm:

1. Do a custom double linked list for the polygon vertices and edges. Using std::list won't do because you must swap next and previous pointers/offsets yourself for a special operation on the nodes. This is the only way to have simple code, and this will give good performance.
2. Find the intersection points by comparing each pair of edges. Note that comparing each pair of edge will give O(N²) time, but improving the algorithm to O(N·logN) will be easy afterwards. For some pair of edges (say a?b and c?d), the intersection point is found by using the parameter (from 0 to 1) on edge a?b, which is given by t?=d0/(d0-d1), where d0 is (c-a)×(b-a) and d1 is (d-a)×(b-a). × is the 2D cross product such as p×q=p?·q?-p?·q?. After having found t?, finding the intersection point is using it as a linear interpolation parameter on segment a?b: P=a+t?(b-a)
3. Split each edge adding vertices (and nodes in your linked list) where the segments intersect.
4. Then you must cross the nodes at the intersection points. This is the operation for which you needed to do a custom double linked list. You must swap some pair of next pointers (and update the previous pointers accordingly).

Then you have the raw result of the polygon intersection resolving algorithm. Normally, you will want to select some region according to the winding number of each region. Search for polygon winding number for an explanation on this.

If you want to make a O(N·logN) algorithm out of this O(N²) one, you must do exactly the same thing except that you do it inside of a line sweep algorithm. Look for Bentley Ottman algorithm. The inner algorithm will be the same, with the only difference that you will have a reduced number of edges to compare, inside of the loop.

You can use the function:

get.elementbyId();

string name;
char *c_string;

getline(cin, name);

c_string = new char[name.length()];

for (int index = 0; index < name.length(); index++){
    c_string[index] = name[index];
}
c_string[name.length()] = '\0';//add the null terminator at the end of
                              // the char array

I know this is not the predefined method but thought it may be useful to someone nevertheless.

The inherit value:

a { color: inherit; } 

… will cause the element to take on the colour of its parent (which is what I think you are looking for).

A live demo follows:

a {
  color: inherit;
}

<p>The default color of the html element is black. The default colour of the body and of a paragraph is inherited. This
  <a href="http://example.com">link</a> would normally take on the default link or visited color, but has been styled to inherit the color from the paragraph.</p>

SQL standard dates while inserting or updating Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.

So if you are inserting/Updating below 1/1/1753 you will get this error.

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

Of the top of my head, can you try to use the 'q' operator for the string literal

something like

insert all
  into domo_queries values (q'[select 
substr(to_char(max_data),1,4) as year,
substr(to_char(max_data),5,6) as month,
max_data
from dss_fin_user.acq_dashboard_src_load_success
where source = 'CHQ PeopleSoft FS']')
select * from dual;

Note that the single quotes of your predicate are not escaped, and the string sits between q'[...]'.

You can override the IIS default document setting using the web.config

<system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="DefaultPageToBeSet.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>

If you want to build DOM you can use jsdom.

There's also cheerio, it has the jQuery interface and it's a lot faster than older versions of jsdom, although these days they are similar in performance.

You might wanna have a look at htmlparser2, which is a streaming parser, and according to its benchmark, it seems to be faster than others, and no DOM by default. It can also produce a DOM, as it is also bundled with a handler that creates a DOM. This is the parser that is used by cheerio.

parse5 also looks like a good solution. It's fairly active (11 days since the last commit as of this update), WHATWG-compliant, and is used in jsdom, Angular, and Polymer.

And if you want to parse HTML for web scraping, you can use YQL¹. There is a node module for it. YQL I think would be the best solution if your HTML is from a static website, since you are relying on a service, not your own code and processing power. Though note that it won't work if the page is disallowed by the robot.txt of the website, YQL won't work with it.

If the website you're trying to scrape is dynamic then you should be using a headless browser like phantomjs. Also have a look at casperjs, if you're considering phantomjs. And you can control casperjs from node with SpookyJS.

Beside phantomjs there's zombiejs. Unlike phantomjs that cannot be embedded in nodejs, zombiejs is just a node module.

There's a nettuts+ toturial for the latter solutions.

¹ Since Aug. 2014, YUI library, which is a requirement for YQL, is no longer actively maintained, source

Using a char when the variable is a string won't work. Using

switch (hello.charAt(0)) 

you will extract the first character of the hello variable instead of trying to use the variable as it is, in string form. You also need to get rid of your space inside

case 'a '

Add commons-lang3-3.1.jar in your application build path. Use the below code snippet to trim the String array.

String array = {" String", "Tom Selleck "," Fish "};
array = StringUtils.stripAll(array);

Use title attribute. It is a standard HTML attribute and is by default rendered in a tooltip by most desktop browsers.

I'd suggest instead of doing another query with the same parameters just immediately running a SELECT FOUND_ROWS()
