Try this solution:

def binary_int_to_decimal(binary):
    n = 0
    for d in binary:
        n = n * 2 + d

    return n

int len=sizeof(array)/sizeof(int);

Should work.

The manual for json_encode specifies this:

All string data must be UTF-8 encoded.

Thus, try array_mapping utf8_encode() to your array before you encode it:

$arr = array_map('utf8_encode', $arr);
$json = json_encode($arr);

// {"funds":"ComStage STOXX\u00c2\u00aeEurope 600 Techn NR ETF"}

For reference, take a look at the differences between the three examples on this fiddle. The first doesn't use character encoding, the second uses htmlentities and the third uses utf8_encode - they all return different results.

For consistency, you should use utf8_encode().

• json_encode()
• utf8_encode()
• array_map()

Because your image is an inline-block element. You could change it to a block-level element like this:

<img src="queuedError.jpg" style="margin:auto; width:200px;display:block" />

and it will be centered.

Since your local repository is few commits ahead, git tries to merge your remote to your local repo. This can be handled via merge, but in your case, perhaps you are looking for rebase, i.e. add your commit to the top. You can do this with

git rebase or git pull --rebase

Here is a good article explaining the difference between git pull & git pull --rebase.

https://www.derekgourlay.com/blog/git-when-to-merge-vs-when-to-rebase/

If you have LineageOS 7.1.2 (and have root), try this solution from XDA.

After having tried all the solutions proposed here, none of which worked for my Nexus 4 (mako), I found one on XDA that solves the problem with the Android dialer (but not with other apps). Basically I downloaded a recompiled version of the Dialer.apk file, which simply ignores the proximity sensor and behaves in the same way as the stock dialer app does.

Rename /system/priv-app/Dialer/Dialer.apk to something, then place the downloaded file to that folder. After reboot, I had to install the new dialer manually (simply by clicking on it). So now the original app is replaced, and the calls should be handled by this new one.

[Downside: the new way to answer a call is by pulling down the status bar and clicking 'Answer' (or 'Dismiss'), the usual slider is missing. Also, you'll need to repeat this every time your Android updates to a newer version.]

There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:

function get-loggedonuser ($computername){

#mjolinor 3/17/10

$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'

$logontype = @{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}

$logon_sessions = @(gwmi win32_logonsession -ComputerName $computername)
$logon_users = @(gwmi win32_loggedonuser -ComputerName $computername)

$session_user = @{}

$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}


$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)

$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime

$loggedonuser
}

}

Since MultiMarkdown was mentioned as an option in comments.

In MultiMarkdown the syntax for an internal link is simple.

For any heading in the document simply give the heading name in this format [heading][] to create an internal link.

Read more here: MultiMarkdown-5 Cross-references.

Cross-References

An oft-requested feature was the ability to have Markdown automatically handle within-document links as easily as it handled external links. To this aim, I added the ability to interpret [Some Text][] as a cross-link, if a header named “Some Text” exists.

As an example, [Metadata][] will take you to # Metadata (or any of ## Metadata, ### Metadata, #### Metadata, ##### Metadata, ###### Metadata).

Alternatively, you can include an optional label of your choosing to help disambiguate cases where multiple headers have the same title:

### Overview [MultiMarkdownOverview] ##

This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers.

If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence.

In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.

You can do it using streams map function like below, get result in new stream for further processing.

Stream<Fruit> newFruits = fruits.stream().map(fruit -> {fruit.name+="s"; return fruit;});
        newFruits.forEach(fruit->{
            System.out.println(fruit.name);
        });

It's not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing.

In other words, %count% is replaced with its value 1 before running the loop.

What you need is something like:

setlocal enableextensions enabledelayedexpansion
set /a count = 1
for /f "tokens=*" %%a in (config.properties) do (
  set /a count += 1
  echo !count!
)
endlocal

Delayed expansion using ! instead of % will give you the expected behaviour. See also here.

Also keep in mind that setlocal/endlocal actually limit scope of things changed inside so that they don't leak out. If you want to use count after the endlocal, you have to use a "trick" made possible by the very problem you're having:

endlocal && set count=%count%

Let's say count has become 7 within the inner scope. Because the entire command is interpreted before execution, it effectively becomes:

endlocal && set count=7

Then, when it's executed, the inner scope is closed off, returning count to it's original value. But, since the setting of count to seven happens in the outer scope, it's effectively leaking the information you need.

You can string together multiple sub-commands to leak as much information as you need:

endlocal && set count=%count% && set something_else=%something_else%

To upload an image simple drag and drop from ur desktop or from anywhere n u can achieve this by copying the image and pasting it on the text area using ctrl+v

An utility method like the following can be used to solve this.

import (
  "os"
  "path/filepath"
  "log"
)

func ensureDir(fileName string) {
  dirName := filepath.Dir(fileName)
  if _, serr := os.Stat(dirName); serr != nil {
    merr := os.MkdirAll(dirName, os.ModePerm)
    if merr != nil {
        panic(merr)
    }
  }
}



func main() {
  _, cerr := os.Create("a/b/c/d.txt")
  if cerr != nil {
    log.Fatal("error creating a/b/c", cerr)
  }
  log.Println("created file in a sub-directory.")
}

public void reverseLinkedList(Node node){
    if(node==null){
        return;
    }

    reverseLinkedList(node.next);
    Node temp = node.next;
    node.next=node.prev;
    node.prev=temp;
    return;
}

I faced a similar issue where XML was containing control characters. After looking into the code, I found that a deprecated class,StringBufferInputStream, was used for reading string content.

http://docs.oracle.com/javase/7/docs/api/java/io/StringBufferInputStream.html

This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the StringReader class.

I changed it to ByteArrayInputStream and it worked fine.

SRCS=$(wildcard *.c)

OBJS=$(SRCS:.c=.o)

all: $(OBJS)

android:singleLine is now deprecated. From the documentation:

This constant was deprecated in API level 3.

This attribute is deprecated. Use maxLines instead to change the layout of a static text, and use the textMultiLine flag in the inputType attribute instead for editable text views (if both singleLine and inputType are supplied, the inputType flags will override the value of singleLine).

So you could just set android:inputType="textEmailSubject" or any other value that matches the content of the field.

While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

You can also use the element selectors:

mat-header-cell:nth-child(1), mat-cell:nth-child(1) {
    flex: 0 0 64px;
}

But jymdman's answer is the most recommended way to go in most cases.

select * from tbl where (endDate>=@starDate and startDate<=@endDate)

attached the diagram for explanation

storing simple data in DB StartDate =10/01/2020 and endDate=20/01/2020. user can provide @startDate(d1) and @endDate(d2) to search.

here 6 scenarios can happen depicted by the 4 red lines (match data) 2 green lines (no match data).

so by conclusion from the image, to get data from DB by providing d1,d2. ED must be greater than d1(@startDate) and SD must be less than d2(@endDate).

I wrote for Visual Basic users :

Protected Function HasColumnAndValue(ByRef reader As IDataReader, ByVal columnName As String) As Boolean
    For i As Integer = 0 To reader.FieldCount - 1
        If reader.GetName(i).Equals(columnName) Then
            Return Not IsDBNull(reader(columnName))
        End If
    Next

    Return False
End Function

I think this is more powerful and the usage is :

If HasColumnAndValue(reader, "ID_USER") Then
    Me.UserID = reader.GetDecimal(reader.GetOrdinal("ID_USER")).ToString()
End If

You could loop through the array and in each iteration call the randomFill method. Check it out:

import java.util.Random;

public class NumberList {
    private static double[] anArray;

    public static double[] list() {  
        return new double[10];
    }

    public static void print() {
        System.out.println(String.join(" ", anArray));
    }


    public static double randomFill() {
        return (new Random()).nextInt();
    }

    public static void main(String args[]) {
        list();
        for(int i = 0; i < anArray.length; i++)
            anArray[i] = randomFill();

        print();
    }
}

The STAThreadAttribute marks a thread to use the Single-Threaded COM Apartment if COM is needed. By default, .NET won't initialize COM at all. It's only when COM is needed, like when a COM object or COM Control is created or when drag 'n' drop is needed, that COM is initialized. When that happens, .NET calls the underlying CoInitializeEx function, which takes a flag indicating whether to join the thread to a multi-threaded or single-threaded apartment.

Why is STAThread required?

outgoing url in mvc generated based on the current routing schema.

because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.

to solve this problem you should use UrlParameter.Optional:

 <a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>

If above answers will not work, try to check your code,,In my experience,having an infinite loop will also cause that problem.Check your else if statement.

I have used this in the past.

In recent versions of Git you can add multiple pushurls for a given remote. Use the following to add two pushurls to your origin:

git remote set-url --add --push origin git://original/repo.git
git remote set-url --add --push origin git://another/repo.git

So when you push to origin, it will push to both repositories.

UPDATE 1: Git 1.8.0.1 and 1.8.1 (and possibly other versions) seem to have a bug that causes --add to replace the original URL the first time you use it, so you need to re-add the original URL using the same command. Doing git remote -v should reveal the current URLs for each remote.

UPDATE 2: Junio C. Hamano, the Git maintainer, explained it's how it was designed. Doing git remote set-url --add --push <remote_name> <url> adds a pushurl for a given remote, which overrides the default URL for pushes. However, you may add multiple pushurls for a given remote, which then allows you to push to multiple remotes using a single git push. You can verify this behavior below:

$ git clone git://original/repo.git
$ git remote -v
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.'
remote.origin.url=git://original/repo.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*

Now, if you want to push to two or more repositories using a single command, you may create a new remote named all (as suggested by @Adam Nelson in comments), or keep using the origin, though the latter name is less descriptive for this purpose. If you still want to use origin, skip the following step, and use origin instead of all in all other steps.

So let's add a new remote called all that we'll reference later when pushing to multiple repositories:

$ git remote add all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)               <-- ADDED
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git            <-- ADDED
remote.all.fetch=+refs/heads/*:refs/remotes/all/* <-- ADDED

Then let's add a pushurl to the all remote, pointing to another repository:

$ git remote set-url --add --push all git://another/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)                 <-- CHANGED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git         <-- ADDED

Here git remote -v shows the new pushurl for push, so if you do git push all master, it will push the master branch to git://another/repo.git only. This shows how pushurl overrides the default url (remote.all.url).

Now let's add another pushurl pointing to the original repository:

$ git remote set-url --add --push all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git
remote.all.pushurl=git://original/repo.git        <-- ADDED

You see both pushurls we added are kept. Now a single git push all master will push the master branch to both git://another/repo.git and git://original/repo.git.

JLabel label = new JLabel ("Text Color: Red");
label.setForeground (Color.red);

this should work

To achieve desired look of SearchView, you can use styles.

First, you need to create style for your SearchView, which should look something like this:

<style name="CustomSearchView" parent="Widget.AppCompat.SearchView">
    <item name="searchIcon">@null</item>
    <item name="queryBackground">@null</item>
</style>

Whole list of attributes you can find at this article, under the "SearchView" section.

Secondly, you need to create a style for your Toolbar, which is used as ActionBar:

<style name="ToolbarSearchView" parent="Base.ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="searchViewStyle">@style/CustomSearchView</item>
</style>

And finally you need to update your Toolbar theme attribute this way:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:theme="@style/ToolbarSearchView" />

Result:

NOTE: You need to change your Toolbar theme attribute directly. If you'll just update your main theme searchViewStyle attribute it wouldn't affect your Toolbar.

{INDEX|KEY}

So KEY is an INDEX ;)

Adding the correct link here Kebab Case

which is All lowercase with - separating words.

I suggest using ES5 array methods:

["myCircle1","myCircle2","myCircle3","myCircle4"] // Array of IDs
.map(document.getElementById, document)           // Array of elements
.forEach(doStuff);

Then doStuff will be called once for each element, and will receive 3 arguments: the element, the index of the element inside the array of elements, and the array of elements.

Updating an entry:

A simple increment should do the trick.

UPDATE mytable 
  SET logins = logins + 1 
  WHERE id = 12

Insert new row, or Update if already present:

If you would like to update a previously existing row, or insert it if it doesn't already exist, you can use the REPLACE syntax or the INSERT...ON DUPLICATE KEY UPDATE option (As Rob Van Dam demonstrated in his answer).

Inserting a new entry:

Or perhaps you're looking for something like INSERT...MAX(logins)+1? Essentially you'd run a query much like the following - perhaps a bit more complex depending on your specific needs:

INSERT into mytable (logins) 
  SELECT max(logins) + 1 
  FROM mytable

You can't do this because the table variables are out of scope.

You would have to declare the table variable inside the dynamic SQL statement or create temporary tables.

I would suggest you read this excellent article on dynamic SQL.

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

You need to escape those but don't just replace it by %2F manually. You can use URLEncoder for this.

Eg URLEncoder.encode(url, "UTF-8")

Then you can say

yourUrl = "www.musicExplained/index.cfm/artist/" + URLEncoder.encode(VariableName, "UTF-8")

Here is the what I have done to avoid CrossThreadException and writing to the textbox from another thread.

Here is my Button.Click function- I want to generate a random number of threads and then get their IDs by calling the getID() method and the TextBox value while being in that worker thread.

private void btnAppend_Click(object sender, EventArgs e) 
{
    Random n = new Random();

    for (int i = 0; i < n.Next(1,5); i++)
    {
        label2.Text = "UI Id" + ((Thread.CurrentThread.ManagedThreadId).ToString());
        Thread t = new Thread(getId);
        t.Start();
    }
}

Here is getId (workerThread) code:

public void getId()
{
    int id = Thread.CurrentThread.ManagedThreadId;
    //Note that, I have collected threadId just before calling this.Invoke
    //method else it would be same as of UI thread inside the below code block 
    this.Invoke((MethodInvoker)delegate ()
    {
        inpTxt.Text += "My id is" +"--"+id+Environment.NewLine; 
    });
}

Managed code is what C#.Net, VB.Net, F#.Net etc compilers create. It runs on the CLR, which among other things offers services like garbage collection, and reference checking, and much more. So think of it as, my code is managed by the CLR.

On the other hand, unmanaged code compiles straight to machine code. It doesn't manage by CLR.

If you want all the paths, use recursion.

Using an adjacency list, preferably, create a function f() that attempts to fill in a current list of visited vertices. Like so:

void allPaths(vector<int> previous, int current, int destination)
{
    previous.push_back(current);

    if (current == destination)
        //output all elements of previous, and return

    for (int i = 0; i < neighbors[current].size(); i++)
        allPaths(previous, neighbors[current][i], destination);
}

int main()
{
    //...input
    allPaths(vector<int>(), start, end);
}

Due to the fact that the vector is passed by value (and thus any changes made further down in the recursive procedure aren't permanent), all possible combinations are enumerated.

You can gain a bit of efficiency by passing the previous vector by reference (and thus not needing to copy the vector over and over again) but you'll have to make sure that things get popped_back() manually.

One more thing: if the graph has cycles, this won't work. (I assume in this case you'll want to find all simple paths, then) Before adding something into the previous vector, first check if it's already in there.

If you want all shortest paths, use Konrad's suggestion with this algorithm.

Rather than silencing the warnings, gcc style is usually to use either standard C constructs or the __attribute__ extension to tell the compiler more about your intention. For instance, the warning about assignment used as a condition is suppressed by putting the assignment in parentheses, i.e. if ((p=malloc(cnt))) instead of if (p=malloc(cnt)). Warnings about unused function arguments can be suppressed by some odd __attribute__ I can never remember, or by self-assignment, etc. But generally I prefer just globally disabling any warning option that generates warnings for things that will occur in correct code.

I had to do this and used subprocess.

import subprocess

subprocess.run("python3 script1.py & python3 script2.py", shell=True)

This is what you want:

>>> string1 = "go"
>>> string2 = "now"
>>> string3 = "great"
>>> mystring = """
... I will {string1} there
... I will go {string2}
... {string3}
... """
>>> locals()
{'__builtins__': <module '__builtin__' (built-in)>, 'string3': 'great', '__package__': None, 'mystring': "\nI will {string1} there\nI will go {string2}\n{string3}\n", '__name__': '__main__', 'string2': 'now', '__doc__': None, 'string1': 'go'}
>>> print(mystring.format(**locals()))

I will go there
I will go now
great

Here is a method for getting a random color:

private static Random sRandom;

public static synchronized int randomColor() {
    if (sRandom == null) {
        sRandom = new Random();
    }
    return 0xff000000 + 256 * 256 * sRandom.nextInt(256) + 256 * sRandom.nextInt(256)
            + sRandom.nextInt(256);
}

Benefits:

• Get the integer representation which can be used with java.awt.Color or android.graphics.Color
• Keep a static reference to Random.

types.Values.ToList().IndexOf("one");

Values.ToList() converts your dictionary values into a List of objects. IndexOf("one") searches your new List looking for "one" and returns the Index which would match the index of the Key/Value pair in the dictionary.

This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.

Keep in mind there may be more than one "one" value in your dictionary. And that is the reason there is no "get key" method.

Setting IsSynchronizedWithCurrentItem="True" worked for me!

Turns out that YUI's reset CSS strips the list style from 'ul li' instead of just 'ul', which is why setting it just in 'ul' never worked.

if you are using mysql this code you can use.

string con = "SERVER=localhost; user id=root; password=; database=databasename";
    private void loaddata()
{
MySqlConnection connect = new MySqlConnection(con);
connect.Open();
try
{
MySqlCommand cmd = connect.CreateCommand();
cmd.CommandText = "SELECT * FROM DATA1";
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
datagrid.DataSource = dt;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Another method is to change the socket so it never generates SIGPIPE on write(). This is more convenient in libraries, where you might not want a global signal handler for SIGPIPE.

On most BSD-based (MacOS, FreeBSD...) systems, (assuming you are using C/C++), you can do this with:

int set = 1;
setsockopt(sd, SOL_SOCKET, SO_NOSIGPIPE, (void *)&set, sizeof(int));

With this in effect, instead of the SIGPIPE signal being generated, EPIPE will be returned.

You may be able to replace the:

VirtualHost ipaddress:443

with

VirtualHost *:443

You probably need todo this on all of your virt hosts.

It will probably clear up that message. Let the ServerName directive worry about routing the message request.

Again, you may not be able to do this if you have multiple ip's aliases to the same machine.

Change your .\SQLEXPRESS,and add your SQL express name only and it works for me

It seems that with ASP.NET Core 2, you can again inherit AuthorizeAttribute, you just need to also implement IAuthorizationFilter (or IAsyncAuthorizationFilter):

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class CustomAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    private readonly string _someFilterParameter;

    public CustomAuthorizeAttribute(string someFilterParameter)
    {
        _someFilterParameter = someFilterParameter;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;

        if (!user.Identity.IsAuthenticated)
        {
            // it isn't needed to set unauthorized result 
            // as the base class already requires the user to be authenticated
            // this also makes redirect to a login page work properly
            // context.Result = new UnauthorizedResult();
            return;
        }

        // you can also use registered services
        var someService = context.HttpContext.RequestServices.GetService<ISomeService>();

        var isAuthorized = someService.IsUserAuthorized(user.Identity.Name, _someFilterParameter);
        if (!isAuthorized)
        {
            context.Result = new StatusCodeResult((int)System.Net.HttpStatusCode.Forbidden);
            return;
        }
    }
}

Is declaring a variable as private static varName; any different from declaring a variable private varName;?

Yes, both are different. And the first one is called class variable because it holds single value for that class whereas the other one is called instance variable because it can hold different value for different instances(Objects). The first one is created only once in jvm and other one is created once per instance i.e if you have 10 instances then you will have 10 different private varName; in jvm.

Does declaring the variable as static give it other special properties?

Yes, static variables gets some different properties than normal instance variables. I've mentioned few already and let's see some here: class variables (instance variables which are declared as static) can be accessed directly by using class name like ClassName.varName. And any object of that class can access and modify its value unlike instance variables are accessed by only its respective objects. Class variables can be used in static methods.

What is the use of a private static variable in Java?

Logically, private static variable is no different from public static variable rather the first one gives you more control. IMO, you can literally replace public static variable by private static variable with help of public static getter and setter methods.

One widely used area of private static variable is in implementation of simple Singleton pattern where you will have only single instance of that class in whole world. Here static identifier plays crucial role to make that single instance is accessible by outside world(Of course public static getter method also plays main role).

public class Singleton {
    private static Singleton singletonInstance = new Singleton();

    private Singleton(){}

    public static Singleton getInstance(){
        return Singleton.singletonInstance;
    }
}

The easiest way to fix this was to press (CTRL) and (,) in VS Code to open Settings.

After that, on the search bar search for code runner, then scroll down and search for Run In Terminal and check that box as highlighted in the below image:

In my experience, this error was as a result of improper naming of aliases in Webpack. In that I had an alias named redux and webpack tried looking for the redux that comes with the redux package in my alias path.

To fix this, I had to rename the alias to something different like Redux.

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

in IntelliJ 2020 in the pom.xml view one should be able to apply pom changes by following key combination: CTRG + SHIFT + O.

And as correctly commented before - IntelliJ additionally shows a balloon widget to import changes.

They always say it depends but when it comes to mirroring a website The best exists httrack. It is super fast and easy to work. The only downside is it's so called support forum but you can find your way using official documentation. It has both GUI and CLI interface and it Supports cookies just read the docs This is the best.(Be cureful with this tool you can download the whole web on your harddrive)

httrack -c8 [url]

By default maximum number of simultaneous connections limited to 8 to avoid server overload

As mentioned before you can use --extra-vars (-e) , but instead of specifying the pwd on the commandline so it doesn't end up in the history files you can save it to an environment variable. This way it also goes away when you close the session.

Other answers have focused more on the multithreading vs multiprocessing aspect, but in python Global Interpreter Lock (GIL) has to be taken into account. When more number (say k) of threads are created, generally they will not increase the performance by k times, as it will still be running as a single threaded application. GIL is a global lock which locks everything out and allows only single thread execution utilizing only a single core. The performance does increase in places where C extensions like numpy, Network, I/O are being used, where a lot of background work is done and GIL is released.
So when threading is used, there is only a single operating system level thread while python creates pseudo-threads which are completely managed by threading itself but are essentially running as a single process. Preemption takes place between these pseudo threads. If the CPU runs at maximum capacity, you may want to switch to multiprocessing.
Now in case of self-contained instances of execution, you can instead opt for pool. But in case of overlapping data, where you may want processes communicating you should use multiprocessing.Process.

On my side, this error came from the data type "INT' in the Null values column. The error is resolved by just changing the data a type to varchar.

simply add a border: 2px solid #e60000; to your 2nd div tag CSS.

Definitely it works

#Div2Id {
    border: 2px solid #e60000; --> color is your preference
}

Every object has to be named inside the parent object:

{ "data": {
    "stuff": {
        "onetype": [
            { "id": 1, "name": "" },
            { "id": 2, "name": "" }
        ],
        "othertype": [
            { "id": 2, "xyz": [-2, 0, 2], "n": "Crab Nebula", "t": 0, "c": 0, "d": 5 }
        ]
    },
    "otherstuff": {
        "thing":
            [[1, 42], [2, 2]]
    }
}
}

So you cant declare an object like this:

var obj = {property1, property2};

It has to be

var obj = {property1: 'value', property2: 'value'};

The source code for the Android mobile application open-gpstracker which you appreciated is available here.

You can checkout the code using SVN client application or via Git:

• svn checkout http://open-gpstracker.googlecode.com/svn/trunk/ open-gpstracker-read-only
• git clone https://code.google.com/p/open-gpstracker/

Debugging the source code will surely help you.

span:not(:last-child) {
    margin-right: 10px;
}

Extra answer: if you are doing this from chroot.

You need source of random numbers to be able to establish secure connection to pypi.

On linux, you can bind-mount host dev to chroot dev:

mount --bind /dev /path-to-chroot/dev

C++ places the default parameter logic in the calling side, this means that if the default value expression cannot be computed from the calling place, then the default value cannot be used.

Other compilation units normally just include the declaration so default value expressions placed in the definition can be used only in the defining compilation unit itself (and after the definition, i.e. after the compiler sees the default value expressions).

The most useful place is in the declaration (.h) so that all users will see it.

Some people like to add the default value expressions in the implementation too (as a comment):

void foo(int x = 42,
         int y = 21);

void foo(int x /* = 42 */,
         int y /* = 21 */)
{
   ...
}

However, this means duplication and will add the possibility of having the comment out of sync with the code (what's worse than uncommented code? code with misleading comments!).

I prefer the OO approach:

$date = new \DateTimeImmutable('today'); //'today' gives midnight, leave blank for current time.
$futureDate = $date->add(\DateInterval::createFromDateString('+1 Year'))

Use DateTimeImmutable otherwise you will modify the original date too! more on DateTimeImmutable: http://php.net/manual/en/class.datetimeimmutable.php

If you just want from todays date then you can always do:

new \DateTimeImmutable('-1 Month');

Construct both separate queries and joins, then time each of them -- nothing helps more than real-world numbers.

Then even better -- add "EXPLAIN" to the beginning of each query. This will tell you how many subqueries MySQL is using to answer your request for data, and how many rows scanned for each query.

Make is behaving correctly. hello already exists and is not older than the .c files, and therefore there is no more work to be done. There are four scenarios in which make will need to (re)build:

• If you modify one of your .c files, then it will be newer than hello, and then it will have to rebuild when you run make.
• If you delete hello, then it will obviously have to rebuild it
• You can force make to rebuild everything with the -B option. make -B all
• make clean all will delete hello and require a rebuild. (I suggest you look at @Mat's comment about rm -f *.o hello

Why are you grouping by? Do you mean order by?

SELECT player_name, player_salary, player_salary * 1.1 AS NewSalary
FROM players
ORDER BY player_salary, player_name;

Or place the image in a location relative to a class and you don't need all that package/path info in the string itself.

com.xyz.SomeClassInThisPackage.class.getResource( "resources/camera.png" );

That way if you move the class to a different package, you dont have to find all the strings, you just move the class and its resources directory.

Perhaps:

> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)

var ary = ['first', 'second', 'third', 'fourth', 'fifth'];

console.log(Object.keys(ary)[0]);

Make any Object array (req), then simply do Object.keys(req)[0] to pick the first key in the Object array.

IF you are using Vector3 this is what i did

1- I create a class Name it Player

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[Serializable]
public class Player
{
    public Vector3[] Position;

}

2- then i call it like this

if ( _ispressed == true)
        {
            Player playerInstance = new Player();
            playerInstance.Position = newPos;
            string jsonData = JsonUtility.ToJson(playerInstance);

            reference.Child("Position" + Random.Range(0, 1000000)).SetRawJsonValueAsync(jsonData);
            Debug.Log(jsonData);
            _ispressed = false;
        }

3- and this is the result

"Position":[ {"x":-2.8567452430725099,"y":-2.4323320388793947,"z":0.0}]}

Are you sure you are on the local an-other-branch when you merge?

git fetch origin an-other-branch
git checkout an-other-branch
git merge origin/an-other-branch

The other explanation:

all the changes from the branch you’re trying to merge have already been merged to the branch you’re currently on.
More specifically it means that the branch you’re trying to merge is a parent of your current branch

if you're ahead of the remote repo by one commit, it's the remote repo that's out of date, not you.

But in your case, if git pull works, that just means you are not on the right branch.

A secondary option would be to match and return non-digits with some expression similar to,

/\D+/g

which would likely work for that specific string in the question (1 ding ?).

Demo

Test

function non_digit_string(str) {_x000D_
 const regex = /\D+/g;_x000D_
 let m;_x000D_
_x000D_
 non_digit_arr = [];_x000D_
 while ((m = regex.exec(str)) !== null) {_x000D_
  // This is necessary to avoid infinite loops with zero-width matches_x000D_
  if (m.index === regex.lastIndex) {_x000D_
   regex.lastIndex++;_x000D_
  }_x000D_
_x000D_
_x000D_
  m.forEach((match, groupIndex) => {_x000D_
   if (match.trim() != '') {_x000D_
    non_digit_arr.push(match.trim());_x000D_
   }_x000D_
  });_x000D_
 }_x000D_
 return non_digit_arr;_x000D_
}_x000D_
_x000D_
const str = `1 ding ? 124_x000D_
12 ding ?_x000D_
123 ding ? 123`;_x000D_
console.log(non_digit_string(str));

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

RegEx Circuit

jex.im visualizes regular expressions:

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>

Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize and add following two methods:

public class SerilizeDeserialize
{

    // Serialize collection of any type to a byte stream

    public static byte[] Serialize<T>(T obj)
    {
        using (MemoryStream memStream = new MemoryStream())
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            binSerializer.Serialize(memStream, obj);
            return memStream.ToArray();
        }
    }

    // DSerialize collection of any type to a byte stream

    public static T Deserialize<T>(byte[] serializedObj)
    {
        T obj = default(T);
        using (MemoryStream memStream = new MemoryStream(serializedObj))
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            obj = (T)binSerializer.Deserialize(memStream);
        }
        return obj;
    }

}

How To use these method in your Class:

ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);

ArrayList arrayListMemDes = new ArrayList();

arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);

Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
    Console.WriteLine(item);
}

You'll first need to separate your numpy array into two separate arrays containing x and y values.

x = [1, 2, 3, 9]
y = [1, 4, 1, 3]

curve_fit also requires a function that provides the type of fit you would like. For instance, a linear fit would use a function like

def func(x, a, b):
    return a*x + b

scipy.optimize.curve_fit(func, x, y) will return a numpy array containing two arrays: the first will contain values for a and b that best fit your data, and the second will be the covariance of the optimal fit parameters.

Here's an example for a linear fit with the data you provided.

import numpy as np
from scipy.optimize import curve_fit

x = np.array([1, 2, 3, 9])
y = np.array([1, 4, 1, 3])

def fit_func(x, a, b):
    return a*x + b

params = curve_fit(fit_func, x, y)

[a, b] = params[0]

This code will return a = 0.135483870968 and b = 1.74193548387

Here's a plot with your points and the linear fit... which is clearly a bad one, but you can change the fitting function to obtain whatever type of fit you would like.

EF Core 2.1+ :

Property:

public string[] Strings { get; set; }

OnModelCreating:

modelBuilder.Entity<YourEntity>()
            .Property(e => e.Strings)
            .HasConversion(
                v => string.Join(',', v),
                v => v.Split(',', StringSplitOptions.RemoveEmptyEntries));

Update (2021-02-14)

The PostgreSQL has an array data type and the Npgsql EF Core provider does support that. So it will map your C# arrays and lists to the PostgreSQL array data type automatically and no extra config is required. Also you can operate on the array and the operation will be translated to SQL.

defaultdict can do something like that for you.

Example:

>>> from collections import defaultdict
>>> d = defaultdict(list)
>>> d
defaultdict(<class 'list'>, {})
>>> d['new'].append(10)
>>> d
defaultdict(<class 'list'>, {'new': [10]})

Building on Graham's answer, the extra code saves the workbook back into it's original location in it's original format.

Public Sub SaveWorksheetsAsCsv()

Dim WS As Excel.Worksheet
Dim SaveToDirectory As String

Dim CurrentWorkbook As String
Dim CurrentFormat As Long

 CurrentWorkbook = ThisWorkbook.FullName
 CurrentFormat = ThisWorkbook.FileFormat
' Store current details for the workbook

      SaveToDirectory = "C:\"

      For Each WS In ThisWorkbook.Worksheets
          WS.SaveAs SaveToDirectory & WS.Name, xlCSV
      Next

 Application.DisplayAlerts = False
  ThisWorkbook.SaveAs Filename:=CurrentWorkbook, FileFormat:=CurrentFormat
 Application.DisplayAlerts = True
' Temporarily turn alerts off to prevent the user being prompted
'  about overwriting the original file.

End Sub

Remove all but 5 (or whatever number) of the most recent files in a directory.

rm `ls -t | awk 'NR>5'`

You can convert hex to RGB:

string ccode = "#00FFFF00";
int argb = Int32.Parse(ccode.Replace("#", ""), NumberStyles.HexNumber);
Color clr = Color.FromArgb(argb);

Your first usage of Map is inside a function in the combat class. That happens before Map is defined, hence the error.

A forward declaration only says that a particular class will be defined later, so it's ok to reference it or have pointers to objects, etc. However a forward declaration does not say what members a class has, so as far as the compiler is concerned you can't use any of them until Map is fully declared.

The solution is to follow the C++ pattern of the class declaration in a .h file and the function bodies in a .cpp. That way all the declarations appear before the first definitions, and the compiler knows what it's working with.

In case you missed it, there's a chapter in the excellent Joshua Bloch's book "Effective Java, 2nd edition".

• Chapter 6 - Enums and Annotations
• Item 34 : Emulate extensible enums with interfaces

Just the conclusion :

A minor disadvantage of the use of interfaces to emulate extensible enums is those implementations cannot be inherited from one enum type to another. In the case of our Operation example, the logic to store and retrieve the symbol associated with an operation is duplicated in BasicOperation and ExtendedOperation. In this case, it doesn’t matter because very little code is duplicated. If there were a a larger amount of shared functionality, you could encapsulate it in a helper class or a static helper method to eliminate the code duplication.

In summary, while you cannot write an extensible enum type, you can emulate it by writing an interface to go with a basic enum type that implements the interface. This allows clients to write their own enums that implement the interface. These enums can then be used wherever the basic enum type can be used, assuming APIs are written in terms of the interface.

You could use regular expressions to replace the '\n' or '\n\r' characters with '<br />'.

you have this:

var h1 = document.createElement("h1");

h1.textContent = "This is a very long string and I would like to insert a carriage return HERE...
moreover, I would like to insert another carriage return HERE... 
so this text will display in a new line";

you can replace your characters like this:

h1.innerHTML = h1.innerHTML.replace(/\n\r?/g, '<br />');

Docker:

I was getting this problem from my Dockerfile as I had:

RUN bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)

However, according to this issue, it was solved:

The exec form makes it possible to avoid shell string munging, and to RUN commands using a base image that does not contain /bin/sh.

Note

To use a different shell, other than /bin/sh, use the exec form passing in the desired shell. For example,

RUN ["/bin/bash", "-c", "echo hello"]

Solution:

RUN ["/bin/bash", "-c", "bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)"]

Notice the quotes around each parameter.

Just append :after to your #alertlist li:hover selector the same way you do with your #alertlist li.selected selector:

#alertlist li.selected:after, #alertlist li:hover:after
{
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}

You need an INSERT ... SELECT

INSERT INTO exception_codes( code, message )
  SELECT code, message
    FROM exception_code_tmp

You want to edit this file: "\xampp\phpMyAdmin\config.inc.php"

change this line:

$cfg['Servers'][$i]['password'] = 'WhateverPassword';

to whatever your password is. If you don't remember your password, then run this command within the Shell:

mysqladmin.exe -u root password WhateverPassword

where WhateverPassword is your new password.

I know others will recommend Apache's http-client, but it adds complexity (i.e., more things that can go wrong) that is rarely warranted. For a simple task, java.net.URL will do.

URL url = new URL("http://www.y.com/url");
InputStream is = url.openStream();
try {
  /* Now read the retrieved document from the stream. */
  ...
} finally {
  is.close();
}

You could try using a Bloom Filter. Insert each number in the bag into the bloom, then iterate over the complete 1-k set until reporting each one not found. This may not find the answer in all scenarios, but might be a good enough solution.

I'm using

Django 2.2

and got the same error while connecting to sql-server 2012. Spent lot of time to solve this issue and finally this worked.

I changed

'driver': 'ODBC Driver 13 for SQL Server'

to

'driver': 'SQL Server Native Client 11.0'

and it worked.

You can also add a middleware to add CORS headers, something like this would work:

/**
 * Adds CORS headers to the response
 *
 * {@link https://en.wikipedia.org/wiki/Cross-origin_resource_sharing}
 * {@link http://expressjs.com/en/4x/api.html#res.set}
 * @param {object} request the Request object
 * @param {object} response the Response object
 * @param {function} next function to continue execution
 * @returns {void}
 * @example
 * <code>
 * const express = require('express');
 * const corsHeaders = require('./middleware/cors-headers');
 *
 * const app = express();
 * app.use(corsHeaders);
 * </code>
 */
module.exports = (request, response, next) => {
    // http://expressjs.com/en/4x/api.html#res.set
    response.set({
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': 'DELETE,GET,PATCH,POST,PUT',
        'Access-Control-Allow-Headers': 'Content-Type,Authorization'
    });

    // intercept OPTIONS method
    if(request.method === 'OPTIONS') {
        response.send(200);
    } else {
        next();
    }
};

I had problem with caching my css files. Setting headers in PHP didn't help me (perhaps because the headers would need to be set in the stylesheet file instead of the page linking to it?).

I found the solution on this page: https://css-tricks.com/can-we-prevent-css-caching/

The solution:

Append timestamp as the query part of the URI for the linked file.
(Can be used for css, js, images etc.)

For development:

<link rel="stylesheet" href="style.css?<?php echo date('Y-m-d_H:i:s'); ?>">

For production (where caching is mostly a good thing):

<link rel="stylesheet" type="text/css" href="style.css?version=3.2">
(and rewrite manually when it is required)

Or combination of these two:

<?php
    define( "DEBUGGING", true ); // or false in production enviroment
?>
<!-- ... -->
<link rel="stylesheet" type="text/css" href="style.css?version=3.2<?php echo (DEBUGGING) ? date('_Y-m-d_H:i:s') : ""; ?>">

EDIT:

Or prettier combination of those two:

<?php
    // Init
    define( "DEBUGGING", true ); // or false in production enviroment
    // Functions
    function get_cache_prevent_string( $always = false ) {
        return (DEBUGGING || $always) ? date('_Y-m-d_H:i:s') : "";
    }
?>
<!-- ... -->
<link rel="stylesheet" type="text/css" href="style.css?version=3.2<?php echo get_cache_prevent_string(); ?>">

I've tried a couple of command line XPath utilities and when I realized I am spending too much time googling and figuring out how they work, so I wrote the simplest possible XPath parser in Python which did what I needed.

The script below shows the string value if the XPath expression evaluates to a string, or shows the entire XML subnode if the result is a node:

#!/usr/bin/env python
import sys
from lxml import etree

tree = etree.parse(sys.argv[1])
xpath = sys.argv[2]

for e in tree.xpath(xpath):

    if isinstance(e, str):
        print(e)
    else:
        print((e.text and e.text.strip()) or etree.tostring(e))

It uses lxml — a fast XML parser written in C which is not included in the standard python library. Install it with pip install lxml. On Linux/OSX might need prefixing with sudo.

Usage:

python xmlcat.py file.xml "//mynode"

lxml can also accept an URL as input:

python xmlcat.py http://example.com/file.xml "//mynode" 

Extract the url attribute under an enclosure node i.e. <enclosure url="http:...""..>):

python xmlcat.py xmlcat.py file.xml "//enclosure/@url"

Xpath in Google Chrome

As an unrelated side note: If by chance you want to run an XPath expression against the markup of a web page then you can do it straight from the Chrome devtools: right-click the page in Chrome > select Inspect, and then in the DevTools console paste your XPath expression as $x("//spam/eggs").

Get all authors on this page:

$x("//*[@class='user-details']/a/text()")

At the risk of causing some cringing by purests and c# programmers, you can use multiple statements and else in a one-line if statement in VB. In this example, y ends up 3 and not 7.

i = 1
If i = 1 Then x = 3 : y = 3 Else x = 7 : y = 7

Simple code that gives you the difference with multiple items if you want that:

a=[1,2,3,3,4]
b=[2,4]
tmp = copy.deepcopy(a)
for k in b:
    if k in tmp:
        tmp.remove(k)
print(tmp)

FIXED!

I've been wrestling with the same issue, and just had a breakthrough! We've established that if you give the image a background color or image, the png displays properly on top of it. The black border is gone, but now you've got an opaque background, and that pretty much defeats the purpose.

Then I remembered a rgba to ie filter converter I came across. (Thanks be to Michael Bester). So I wondered what would happen if I gave my problem pngs an ie filtered background emulating rgba(255,255,255,0), fully expecting it not to work, but lets try it anyway...

.item img {
    background: transparent;
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF)"; /* IE8 */   
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF);   /* IE6 & 7 */      
    zoom: 1;

}

Presto! Goodbye black, and hello working alpha channels in ie7 and 8. Fade your pngs in and out, or animate them across the screen - it's all good.

var attr = $(this).attr('name');

// For some browsers, `attr` is undefined; for others,
// `attr` is false.  Check for both.
if (typeof attr !== typeof undefined && attr !== false) {
    // ...
}

here in this code first we are creating RSA key which is private but it has pair of its public key as well so to get your actual public key we simply do this

openssl rsa -in mykey.pem -pubout > mykey.pub

hope you get it for more info check this

I used multiple examples to patch this working one liner together.

This will open your batch script as an ADMIN + Maximized Window

Just add one of the following codes to the top of your batch script. Both ways work, just different ways to code it.

I believe the first example responds the quickest due to /d switch disabling my doskey commands that I have enabled..

EXAMPLE ONE

@ECHO OFF
IF NOT "%1"=="MAX" (powershell -WindowStyle Hidden -NoProfile -Command {Start-Process CMD -ArgumentList '/D,/C' -Verb RunAs} & START /MAX CMD /D /C %0 MAX & EXIT /B)
:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Your original batch code here:

:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

EXAMPLE TWO

@ECHO OFF
IF NOT "%1"=="MAX" (powershell -WindowStyle Hidden -NoProfile -Command "Start-Process CMD -ArgumentList '/C' -Verb RunAs" & START /MAX CMD /C "%0" MAX & EXIT /B)
:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Your original batch code here:

:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

See below for recommendations when using your original batch code

Place the original batch code in it's entirety

Just because the first line of code at the very top has @ECHO OFF doesn't mean you should not include it again if your original script has it as well.

This ensures that when the script get's restarted in a new window now running in admin mode that you don't lose your intended script parameters/attributes... Such as the current working directory, your local variables, and so on

You could beginning with the following commands to avoid some of these issues

:: Make sure to use @ECHO OFF if your original code had it
@ECHO OFF
:: Avoid clashing with other active windows variables with SETLOCAL
SETLOCAL
:: Nice color to work with using 0A
COLOR 0A
:: Give your script a name
TITLE NAME IT!

:: Ensure your working directory is set where you want it to be
:: the following code sets the working directory to the script directory folder
PUSHD "%~dp0"

THE REST OF YOUR SCRIPT HERE...

:: Signal the script is finished in the title bar
ECHO.
TITLE Done! NAME IT!
PAUSE
EXIT

To create the regex from a string, you have to use JavaScript's RegExp object.

If you also want to match/replace more than one time, then you must add the g (global match) flag. Here's an example:

var stringToGoIntoTheRegex = "abc";
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

In the general case, escape the string before using as regex:

Not every string is a valid regex, though: there are some speciall characters, like ( or [. To work around this issue, simply escape the string before turning it into a regex. A utility function for that goes in the sample below:

function escapeRegExp(stringToGoIntoTheRegex) {
    return stringToGoIntoTheRegex.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}

var stringToGoIntoTheRegex = escapeRegExp("abc"); // this is the only change from above
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

Note: the regex in the question uses the s modifier, which didn't exist at the time of the question, but does exist -- a s (dotall) flag/modifier in JavaScript -- today.

No. Java methods can only return one result (void, a primitive, or an object), and creating a struct-type class like this is exactly how you do it.

As a note, it is frequently possible to make classes like your ReturningValues immutable like this:

public class ReturningValues {
    public final String value;
    public final int index;

    public ReturningValues(String value, int index) {
        this.value = value;
        this.index = index;
    }
}

This has the advantage that a ReturningValues can be passed around, such as between threads, with no concerns about accidentally getting things out of sync.

In my case, it happenned for the master branch. Later found that my access to the project was accidentally revoked by the project manager. To cross-check, I visited the review site and couldn't see any commits of the said branch and others for that project.

Since variable names in the BASH shell cannot contain a dot or space it is better to use an associative array in BASH like this:

#!/bin/bash

# declare an associative array
declare -A arr

# read file line by line and populate the array. Field separator is "="
while IFS='=' read -r k v; do
   arr["$k"]="$v"
done < app.properties

Testing:

Use declare -p to show the result:

  > declare -p arr  

        declare -A arr='([db.uat.passwd]="secret" [db.uat.user]="saple user" )'

Have you tried loading the socket.io script not from a relative URL?

You're using:

<script src="socket.io/socket.io.js"></script>

And:

socket.connect('http://127.0.0.1:8080');

You should try:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

And:

socket.connect('http://localhost:8080');

Switch localhost:8080 with whatever fits your current setup.

Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).

Note, you can use {{.}} to render the current context item.

{{#avatar}}{{.}}{{/avatar}}

{{^avatar}}missing{{/avatar}}

If you are using Kotlin

    this.findViewById<View>(android.R.id.content)
                         .rootView
                         .setBackgroundColor(ContextCompat.getColor(this, R.color.black))

Make use of *(B) instead of *B[0]. Here, *(B+i) implies B[i] and *(B) implies B[0], that is
*(B+0)=*(B)=B[0].

#include <stdio.h>

int func(int *B){
    *B = 5;     
    // if you want to modify ith index element in the array just do *(B+i)=<value>
}

int main(void){

    int B[10] = {};
    printf("b[0] = %d\n\n", B[0]);
    func(B);
    printf("b[0] = %d\n\n", B[0]);
    return 0;
}

To do it from a Base64 encoding you can use the following function:

function base64ToArrayBuffer(data) {
  const bString = window.atob(data);
  const bLength = bString.length;
  const bytes = new Uint8Array(bLength);
  for (let i = 0; i < bLength; i++) {
      bytes[i] = bString.charCodeAt(i);
  }
  return bytes;
}
function base64toPDF(base64EncodedData, fileName = 'file') {
  const bufferArray = base64ToArrayBuffer(base64EncodedData);
  const blobStore = new Blob([bufferArray], { type: 'application/pdf' });
  if (window.navigator && window.navigator.msSaveOrOpenBlob) {
      window.navigator.msSaveOrOpenBlob(blobStore);
      return;
  }
  const data = window.URL.createObjectURL(blobStore);
  const link = document.createElement('a');
  document.body.appendChild(link);
  link.href = data;
  link.download = `${fileName}.pdf`;
  link.click();
  window.URL.revokeObjectURL(data);
  link.remove();
}

I used tabularise in Vim to align the columns:

:%Tab /^[^ ]*\zs /r1l1l1
:%Tab /^ *[^ ]* *[^ ]*\zs /l1

For any T object you can do:

return Request.CreateResponse<T>(HttpStatusCode.OK, Tobject);

Thank you guys for the help,

When I asked at first I didn't think it's even possible, but after your answers I googled and found this amazing tutorial:

http://blog.thomaslebrun.net/2011/11/html-5-how-to-customize-the-error-message-for-a-required-field/#.UsNN1BYrh2M

Here is a working example of above. http://jsfiddle.net/z7L6m2sc/ Now select2 has been updated the classes have change may be why you cannot get it to work. Here is the css....

.select2-dropdown.select2-dropdown--below{
    width: 148px !important;
}

.select2-container--default .select2-selection--single{
    padding:6px;
    height: 37px;
    width: 148px; 
    font-size: 1.2em;  
    position: relative;
}

.select2-container--default .select2-selection--single .select2-selection__arrow {
    background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
    background-image: -moz-linear-gradient(top, #424242, #030303);
    background-image: -ms-linear-gradient(top, #424242, #030303);

In scripts you have more options and a better shot at rational decomposition. Look into SQLCMD mode (Query Menu -> SQLCMD mode), specifically the :setvar and :r commands.

Within a stored procedure your options are very limited. You can't create define a function directly with the body of a procedure. The best you can do is something like this, with dynamic SQL:

create proc DoStuff
as begin

  declare @sql nvarchar(max)

  /*
  define function here, within a string
  note the underscore prefix, a good convention for user-defined temporary objects
  */
  set @sql = '
    create function dbo._object_name_twopart (@object_id int)
    returns nvarchar(517) as
    begin
      return 
        quotename(object_schema_name(@object_id))+N''.''+
        quotename(object_name(@object_id))
    end
  '

  /*
  create the function by executing the string, with a conditional object drop upfront
  */
  if object_id('dbo._object_name_twopart') is not null drop function _object_name_twopart
  exec (@sql)

  /*
  use the function in a query
  */
  select object_id, dbo._object_name_twopart(object_id) 
  from sys.objects
  where type = 'U'

  /*
  clean up
  */
  drop function _object_name_twopart

end
go

This approximates a global temporary function, if such a thing existed. It's still visible to other users. You could append the @@SPID of your connection to uniqueify the name, but that would then require the rest of the procedure to use dynamic SQL too.

Starting

I use this bit of code to import sql statements created by mysqldump:

public static void importSQL(Connection conn, InputStream in) throws SQLException
{
    Scanner s = new Scanner(in);
    s.useDelimiter("(;(\r)?\n)|(--\n)");
    Statement st = null;
    try
    {
        st = conn.createStatement();
        while (s.hasNext())
        {
            String line = s.next();
            if (line.startsWith("/*!") && line.endsWith("*/"))
            {
                int i = line.indexOf(' ');
                line = line.substring(i + 1, line.length() - " */".length());
            }

            if (line.trim().length() > 0)
            {
                st.execute(line);
            }
        }
    }
    finally
    {
        if (st != null) st.close();
    }
}

I was using this two lines in the url and the template from the admin what i was changing to my need

url(r'^change-password/$', 'django.contrib.auth.views.password_change', {
    'template_name': 'password_change_form.html'}, name="password-change"),
url(r'^change-password-done/$', 'django.contrib.auth.views.password_change_done', {
    'template_name': 'password_change_done.html'
    }, name="password-change-done")

Suppose there's a file test.txt in Root Folder, and want to move it to \TxtFolder,

You can try

move %~dp0\test.txt %~dp0\TxtFolder

Here's a Split function that is compatible with SQL Server versions prior to 2005.

CREATE FUNCTION dbo.Split(@data nvarchar(4000), @delimiter nvarchar(100))  
RETURNS @result table (Id int identity(1,1), Data nvarchar(4000)) 
AS  
BEGIN 
    DECLARE @pos   INT
    DECLARE @start INT
    DECLARE @len   INT
    DECLARE @end   INT

    SET @len   = LEN('.' + @delimiter + '.') - 2
    SET @end   = LEN(@data) + 1
    SET @start = 1
    SET @pos   = 0

    WHILE (@pos < @end)
    BEGIN
        SET @pos = CHARINDEX(@delimiter, @data, @start)
        IF (@pos = 0) SET @pos = @end

        INSERT @result (data) SELECT SUBSTRING(@data, @start, @pos - @start)
        SET @start = @pos + @len
    END

    RETURN
END

I use https://github.com/yabawock/bootstrap-sass-rails

Which is pretty much straight forward install, fast gem updates and followups and quick fixes in case is needed.

I'm surprised I couldn't find a worthwhile solution here late 2018. I went ahead and figured it out a Bootstrap 3 solution myself using flexbox.

Clean and simple example:

HTML

<div class="row row-equal">
    <div class="col-lg-4 col-md-4 col-sm-4 col-xs-12 col-equal">
        <p>Text</p>
    </div>
    <div class="col-lg-4 col-md-4 col-sm-4 col-xs-12 col-equal">
        <img src="//placehold.it/200x200">
    </div>
    <div class="col-lg-4 col-md-4 col-sm-4 col-xs-12 col-equal">
        <p>Text</p>
    </div>  
</div>

CSS

img {
  width: 100%;
}
p {
  padding: 2em;
}
@media (min-width: 768px) {
  .row-equal {
    display: flex;
    flex-wrap: wrap;
  }
  .col-equal {
    margin: auto;
  }
}

You've not shown how you're creating the string 2016-01-12T23:00:00.000Z, but I assume via .format().

Anyway, .set() is using your local time zone, but the Z in the time string indicates zero time, otherwise known as UTC.

https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators

So I assume your local timezone is 23 hours from UTC?

saikumar's answer showed how to load the time in as UTC, but the other option is to use a .format() call that outputs using your local timezone, rather than UTC.

http://momentjs.com/docs/#/get-set/
http://momentjs.com/docs/#/displaying/format/

>>> keyDict = {"a","b","c","d"}

>>> dict([(key, []) for key in keyDict])

Output:

{'a': [], 'c': [], 'b': [], 'd': []}

I was upgrading a legacy instance of jQuery UI and found that there was an extension to the dialog widget and it was simply using "center" instead of the position object. Implementing the position object or removing the parameter entirely worked for me (because center is the default).

Try this:

created_at.strftime('%FT%T')

It's a time formatting function which provides you a way to present the string representation of the date. (http://ruby-doc.org/core-2.2.1/Time.html#method-i-strftime).

Here's another way to be compatible with an IHttpActionResult return type. In this case I am asking it to use the XML Serializer(optional) instead of Data Contract serializer, I'm using return ResponseMessage( so that I get a return compatible with IHttpActionResult:

return ResponseMessage(new HttpResponseMessage(HttpStatusCode.OK)
       {
           Content = new ObjectContent<SomeType>(objectToSerialize, 
              new System.Net.Http.Formatting.XmlMediaTypeFormatter { 
                  UseXmlSerializer = true 
              })
       });

In C++ you can overload operator<< for ostream and your custom class:

class A {
public:
  int i;
};

std::ostream& operator<<(std::ostream &strm, const A &a) {
  return strm << "A(" << a.i << ")";
}

This way you can output instances of your class on streams:

A x = ...;
std::cout << x << std::endl;

In case your operator<< wants to print out internals of class A and really needs access to its private and protected members you could also declare it as a friend function:

class A {
private:
  friend std::ostream& operator<<(std::ostream&, const A&);
  int j;
};

std::ostream& operator<<(std::ostream &strm, const A &a) {
  return strm << "A(" << a.j << ")";
}

The HTML2PDF and HTML2PS that was originally mentioned in opening post was talking about a 2009 package with this link

But there is a better HTML2PDF

It is based on TCPDF though it is partly in French.

You can have table headers or footers that repeat on the pages and have page numbers and total pages. See its examples. I have been using it for over three years and recommend it.

Actually you should define your styles in res/values/styles.xml. I guess now you've got the following configuration:

<style name="AppBaseTheme" parent="android:Theme.Holo.Light"/>
<style name="AppTheme" parent="AppBaseTheme"/>

so if you want to use Theme.Black then change AppBaseTheme parent to android:Theme.Black or you could change app style directly in manifest file like this - android:theme="@android:style/Theme.Black". You must be lacking android namespace before style tag.

You can read more about styles and themes here.

The answer may be outdated, since there is a name property on the UploadedFile class. See: Uploaded Files and Upload Handlers (Django docs). So, if you bind your form with a FileField correctly, the access should be as easy as:

if form.is_valid():
    form.cleaned_data['my_file'].name

This simple problem can cause a real headache!

I can see your controller EDIT (PUT) method expects 2 parameters: a) an int id, and b) a department object.

It is the default code when you generate this from VS > add controller with read/write options. However, you have to remember to consume this service using the two parameters, otherwise you will get the error 405.

In my case, I did not need the id parameter for PUT, so I just dropped it from the header... after a few hours of not noticing it there! If you keep it there, then the name must also be retained as id, unless you go on to make necessary changes to your configurations.

I don't know why but (for now) httpclient can be compiled only as a jar into the libs directory in your project. HttpCore works fine when it is included from mvn like that:

dependencies {
      compile 'org.apache.httpcomponents:httpcore:4.4.3'
}

I'm not sure what you want, but i'll use lattice.

x = rep(x,2)
y = c(y1,y2)
fac.data = as.factor(rep(1:2,each=5))
df = data.frame(x=x,y=y,z=fac.data)
# this create a data frame where I have a factor variable, z, that tells me which data I have (y1 or y2)

Then, just plot

xyplot(y ~x|z, df)
# or maybe
xyplot(x ~y|z, df)

You can use

var modal_template_html = $.trim($('#modal_template').html());
var template = $(modal_template_html);

CREATE GLOBAL TEMPORARY TABLE Table_name
    (startdate DATE,
     enddate DATE,
     class CHAR(20))
  ON COMMIT DELETE ROWS;

I don't know anything provided by the Framework (beyond what you want to avoid) that would do what you want but (as I suspect you know) it would be pretty easy to create something simple yourself:

private DataTable GetDataTableFromDGV(DataGridView dgv) {
    var dt = new DataTable();
    foreach (DataGridViewColumn column in dgv.Columns) {
        if (column.Visible) {
            // You could potentially name the column based on the DGV column name (beware of dupes)
            // or assign a type based on the data type of the data bound to this DGV column.
            dt.Columns.Add();
        }
    }

    object[] cellValues = new object[dgv.Columns.Count];
    foreach (DataGridViewRow row in dgv.Rows) {
        for (int i = 0; i < row.Cells.Count; i++) {
            cellValues[i] = row.Cells[i].Value;
        }
        dt.Rows.Add(cellValues);
    }

    return dt;
}

arr = arr.filter(v => v);

as returned v is implicity converted to truthy

First of all, you do not have to develop any form yourself : phpMyAdmin, depending on its configuration (i.e. config.inc.php) will display an identification form, asking for a login and password.

To get that form, you should not use :

$cfg['Servers'][$i]['auth_type'] = 'config';

But you should use :

$cfg['Servers'][$i]['auth_type'] = 'cookie';

(At least, that's what I have on a server which prompts for login/password, using a form)

For more informations, you can take a look at the documentation :

• Using authentication modes
• Configuration, which states (quoting) :

'config' authentication ($auth_type = 'config') is the plain old way: username and password are stored in config.inc.php.

'cookie' authentication mode ($auth_type = 'cookie') as introduced in 2.2.3 allows you to log in as any valid MySQL user with the help of cookies.
Username and password are stored in cookies during the session and password is deleted when it ends.

This is quick Bash command, that you're probably searching for, will print only a basename of the remote repository:

Where you fetch from:

basename $(git remote show -n origin | grep Fetch | cut -d: -f2-)

Alternatively where you push to:

basename $(git remote show -n origin | grep Push | cut -d: -f2-)

Especially the -n option makes the command much quicker.

I do not pretend to show something new, just want to summarize solutions above for those who likes to use Promise functions in their code (like me).

const archiver = require('archiver');

/**
 * @param {String} source
 * @param {String} out
 * @returns {Promise}
 */
function zipDirectory(source, out) {
  const archive = archiver('zip', { zlib: { level: 9 }});
  const stream = fs.createWriteStream(out);

  return new Promise((resolve, reject) => {
    archive
      .directory(source, false)
      .on('error', err => reject(err))
      .pipe(stream)
    ;

    stream.on('close', () => resolve());
    archive.finalize();
  });
}

Hope it will help someone ;)

You can simply put javascript expression in ng-model.

You can use negative indexing to remove rows, e.g.:

dat <- dat[-1, ]

Here is an example:

> dat <- data.frame(A = 1:3, B = 1:3)
> dat[-1, ]
  A B
2 2 2
3 3 3
> dat2 <- dat[-1, ]
> dat2
  A B
2 2 2
3 3 3

That said, you may have more problems than just removing the labels that ended up on row 1. It is more then likely that R has interpreted the data as text and thence converted to factors. Check what str(foo), where foo is your data object, says about the data types.

It sounds like you just need header = TRUE in your call to read in the data (assuming you read it in via read.table() or one of it's wrappers.)

SlowCheetah and FastKoala from the VisualStudio Gallery seem to be very good tools that help out with this problem.

However, if you want to avoid addins or use the principles they implement more extensively throughout your build/integration processes then adding this to your msbuild *proj files is a shorthand fix.

Note: this is more or less a rework of the No. 2 of @oleksii's answer.

This works for .exe and .dll projects:

  <Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
    <TransformXml Source="App_Config\app.Base.config" Transform="App_Config\app.$(Configuration).config" Destination="app.config" />
  </Target>

This works for web projects:

  <Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
    <TransformXml Source="App_Config\Web.Base.config" Transform="App_Config\Web.$(Configuration).config" Destination="Web.config" />
  </Target>

Note that this step happens even before the build proper begins. The transformation of the config file happens in the project folder. So that the transformed web.config is available when you are debugging (a drawback of SlowCheetah).

Do remember that if you create the App_Config folder (or whatever you choose to call it), the various intermediate config files should have a Build Action = None, and Copy to Output Directory = Do not copy.

This combines both options into one block. The appropriate one is executed based on conditions. The TransformXml task is defined first though:

<Project>
<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
    <TransformXml Condition="Exists('App_Config\app.Base.config')" Source="App_Config\app.Base.config" Transform="App_Config\app.$(Configuration).config" Destination="app.config" />
    <TransformXml Condition="Exists('App_Config\Web.Base.config')" Source="App_Config\Web.Base.config" Transform="App_Config\Web.$(Configuration).config" Destination="Web.config" />
</Target>

unanswered core problem persists:

My working directory is now c:\users\projectname.git So then I try to import the project using the eclipse "import" option. When I try to import selecting the option "Use the new projects wizard" the source code is not imported, if I import selecting the option "Import as general project" the source code is imported but the created project created by Eclipse is not a java project. When selecting the option "Use the new projects wizard" and creating a new java project using the wizard should'nt the code be automatically imported ?

Yes it should.

It's a bug. Reported here.

Here is a workaround:

• Import as general project

• Notice the imported data is no valid Eclipse project (no build path available)

• Open the .project xml file in the project folder in Eclipse. If you can't see this file, see How can I get Eclipse to show .* files?.

• Go to source tab

• Search for <natures></natures> and change it to <natures><nature>org.eclipse.jdt.core.javanature</nature></natures> and save the file

  (idea comes from here)

• Right click the src folder, go to Build Path... and click Use as Source Folder

After that, you should be able to run & debug the project, and also use team actions via right-click in the package explorer.

If you still have troubles running the project (something like "main class not found"), make sure the <buildSpec> inside the .project file is set (as described here):

<buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
</buildSpec>

It's been a long time since this question was asked but if someone is still interested - I recently ran into similar icons. I was compiling a C#.net project using VS 2008. I found VS could not locate the assemblies for those references. When I double clicked VS refreshed the references and removed the icons on some of those[EDIT: which it could NOW locate]. For remaining references, I had to compile the respective assemblies.

It seems wrong to me to set up an if/else statement just to use the else portion...

Just negate your condition, and you'll get the else logic inside the if:

if (!(id in tutorTimes)) { ... }

I recently submitted an app to Apple's App Store. My app was built using iOS 12, Xcode 10, and Swift 4.2. My app uses Google AdMob for the sole purpose of showing Interstitial Ads. When prompted these question, this is what I did:

1) Does this app use the Advertising Identifier (IDFA)? ANSWER: YES

a) Serve advertisements within the app - CHECKED

b) Attribute this app ... - NOT CHECKED

c) Attribute an action ... - NOT CHECKED

I, (my name), confirm that this app ... - CHECKED

My app was accepted and "Ready for Sale" in less than 24 hrs.

This is not a perfect solution but it sort of does work.

In the select tag, include the following attributes where 'n' is the number of dropdown rows that would be visible.

<select size="1" position="absolute" onclick="size=(size!=1)?n:1;" ...>

There are three problems with this solution. 1) There is a quick flash of all the elements shown during the first mouse click. 2) The position is set to 'absolute' 3) Even if there are less than 'n' items the dropdown box will still be for the size of 'n' items.

Not sure is this could help, but I solved the pinch / zoom problem (I wanted to avoid users to do zooming on my webapp) using angular hammer module:

In my app.component.html I added:

<div id="app" (pinchin)="pinchin();">

and in my app.component.ts:

  pinchin() {
      //console.log('pinch in');
  }

We can add drawable .xml like below

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">


    <stroke
        android:width="1dp"
        android:color="@color/color_C4CDD5"/>

    <corners android:radius="8dp"/>

    <solid
        android:color="@color/color_white"/>

</shape>

I want to add that when using Windows you can use require './1.rb' if the script is run local or from a mapped network drive but when run from an UNC \\servername\sharename\folder path you need to use require_relative './1.rb'.

I don't mingle in the discussion which to use for other reasons.

After a lot of research I found the best solution to reduce the size of custom rating bars is to get the size of progress drawable in certain sizes as mentioned below :

xxhdpi - 48*48 px

xhdpi - 36*36 px

hdpi - 24*24 px

And in style put the minheight and maxheight as 16 dp for all Resolution.

Let me know if this doesn't help you to get a best small size rating bars as these sizes I found very compatible and equivalent to ratingbar.small style attribute.

Select column to drop:

ALTER TABLE my_table
DROP column_to_be_deleted;

However, some databases (including SQLite) have limited support, and you may have to create a new table and migrate the data over:

I had set the new app's application pool to the DefaultAppPool in IIS which obviously is using the Classic pipeline with .NET v.2.0.

To solve the problem I created a new App Pool using the Integrated pipeline and .NET v4.0. just for this new application and then everything started working as expected.

Don't forget to assign this new app pool to the application. Select the application in IIS, click Basic Settings and then pick the new app pool for the app.

If your input is already sorted, then there may be a simpler way to do it:

from operator import itemgetter
from itertools import groupby
unique_list = list(map(itemgetter(0), groupby(yourList)))

I found a much simpler alternative way to generating soap message. Given a Person Object:

import com.fasterxml.jackson.annotation.JsonInclude;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
  private String name;
  private int age;
  private String address; //setter and getters below
}

Below is a simple Soap Message Generator:

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

@Slf4j
public class SoapGenerator {

  protected static final ObjectMapper XML_MAPPER = new XmlMapper()
      .enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
      .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
      .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
      .registerModule(new JavaTimeModule());

  private static final String SOAP_BODY_OPEN = "<soap:Body>";
  private static final String SOAP_BODY_CLOSE = "</soap:Body>";
  private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
  private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";

  public static String soapWrap(String xml) {
    return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
  }

  public static String soapUnwrap(String xml) {
    return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
  }
}

You can use by:

 public static void main(String[] args) throws Exception{
        Person p = new Person();
        p.setName("Test");
        p.setAge(12);

        String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
        log.info("Generated String");
        log.info(xml);
      }

See ?nchar. For example:

> nchar("foo")
[1] 3
> set.seed(10)
> strn <- paste(sample(LETTERS, 10), collapse = "")
> strn
[1] "NHKPBEFTLY"
> nchar(strn)
[1] 10

The best way to send data from a parent component to a child is using props.

Passing data from parent to child via props

• Declare props (array or object) in the child
• Pass it to the child via <child :name="variableOnParent">

See demo below:

Vue.component('child-comp', {
  props: ['message'], // declare the props
  template: '<p>At child-comp, using props in the template: {{ message }}</p>',
  mounted: function () {
    console.log('The props are also available in JS:', this.message);
  }
})

new Vue({
  el: '#app',
  data: {
    variableAtParent: 'DATA FROM PARENT!'
  }
})

<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>

<div id="app">
  <p>At Parent: {{ variableAtParent }}<br>And is reactive (edit it) <input v-model="variableAtParent"></p>
  <child-comp :message="variableAtParent"></child-comp>
</div>

Tip for MULTIPLE VIDEOS on a page: I recently solved an issue with no mp4 playback in Chrome or Firefox (played fine in IE) in a page with 16 videos in modals (bootstrap 3) after discovering the frame rates of all the videos must be identical. I had 6 videos at 25fps and 12 at 29.97fps... after rendering all to 25fps versions, everything runs smooth across all browsers.

In Java 8 the static Map pattern is even easier and is my preffered method. If you want to use the Enum with Jackson you can override toString and use that instead of name, then annotate with @JsonValue

public enum MyEnum {
    BAR,
    BAZ;
    private static final Map<String, MyEnum> MAP = Stream.of(MyEnum.values()).collect(Collectors.toMap(Enum::name, Function.identity()));
    public static MyEnum fromName(String name){
        return MAP.get(name);
    }
}

public enum MyEnumForJson {
    BAR("bar"),
    BAZ("baz");
    private static final Map<String, MyEnumForJson> MAP = Stream.of(MyEnumForJson.values()).collect(Collectors.toMap(Object::toString, Function.identity()));
    private final String value;

    MyEnumForJson(String value) {
        this.value = value;
    }

    @JsonValue
    @Override
    public String toString() {
        return value;
    }

    public static MyEnumForJson fromValue(String value){
        return MAP.get(value);
    }
}

I'm going to assume you do not want to count hidden or system files.

There are many ways to do this. All of the methods that I will show involve some form of the FOR command. There are many variations of the FOR command that look almost the same, but they behave very differently. It can be confusing for a beginner.

You can get help by typing HELP FOR or FOR /? from the command line. But that help is a bit cryptic if you are not used to reading it.

1) The DIR command lists the number of files in the directory. You can pipe the results of DIR to FIND to get the relevant line and then use FOR /F to parse the desired value from the line. The problem with this technique is the string you search for has to change depending on the language used by the operating system.

@echo off
for /f %%A in ('dir ^| find "File(s)"') do set cnt=%%A
echo File count = %cnt%

2) You can use DIR /B /A-D-H-S to list the non-hidden/non-system files without other info, pipe the result to FIND to count the number of files, and use FOR /F to read the result.

@echo off
for /f %%A in ('dir /a-d-s-h /b ^| find /v /c ""') do set cnt=%%A
echo File count = %cnt%

3) You can use a simple FOR to enumerate all the files and SET /A to increment a counter for each file found.

@echo off
set cnt=0
for %%A in (*) do set /a cnt+=1
echo File count = %cnt%

I agree with Levik as the parent container is set to 100% if you have sidebars and want them to fill the space to meet up with the footer you cannot set them to 100% because they will be 100 percent of the parent height as well which means that the footer ends up getting pushed down when using the clear function.

Think of it this way if your header is say 50px height and your footer is 50px height and the content is just autofitted to the remaining space say 100px for example and the page container is 100% of this value its height will be 200px. Then when you set the sidebar height to 100% it is then 200px even though it is supposed to fit snug in between the header and footer. Instead it ends up being 50px + 200px + 50px so the page is now 300px because the sidebars are set to the same height as the page container. There will be a big white space in the contents of the page.

I am using internet Explorer 9 and this is what I am getting as the effect when using this 100% method. I havent tried it in other browsers and I assume that it may work in some of the other options. but it will not be universal.

If you won't always have images posting to your action, you can do something like this:

[HttpPost]
public ActionResult Uploadfile(Container container, HttpPostedFileBase file) 
{
    //do container stuff

    if (Request.Files != null)
    {
        foreach (string requestFile in Request.Files)
        {
            HttpPostedFileBase file = Request.Files[requestFile]; 
            if (file.ContentLength > 0)
            {
                string fileName = Path.GetFileName(file.FileName);
                string directory = Server.MapPath("~/App_Data/uploads/");
                if (!Directory.Exists(directory))
                {
                    Directory.CreateDirectory(directory);
                }
                string path = Path.Combine(directory, fileName);
                file.SaveAs(path);
            }
        }
    }

} 

There has been an open feature request since at least 2009. The long and short of it is that it will part of the functionality of JDK 8's java.util.StringJoiner class. http://download.java.net/lambda/b81/docs/api/java/util/StringJoiner.html

Here is the Oracle issue if you are interested. http://bugs.sun.com/view_bug.do?bug_id=5015163

Here is an example of the new JDK 8 StringJoiner on an array of String

String[] a = new String[]{"first","second","third"};
StringJoiner sj = new StringJoiner(",");
for(String s:a) sj.add(s);
System.out.println(sj); //first,second,third

A utility method in String makes this even simpler:

String s = String.join(",", stringArray);

If you want to insert object, use this:

    currentLogs = [
 { socket_id: 'Server', message: 'Socketio online', data: 'Port  3333', logged: '2014-05-14 14:41:11' },
 { socket_id: 'Server', message: 'Waiting for Pi to connect...', data: 'Port: 8082', logged: '2014-05-14 14:41:11' }
];

console.warn(currentLogs.map(logs=>[ logs.socket_id , logs.message , logs.data , logs.logged ]));

The output will be:

[
  [ 'Server', 'Socketio online', 'Port  3333', '2014-05-14 14:41:11' ],
  [
    'Server',
    'Waiting for Pi to connect...',
    'Port: 8082',
    '2014-05-14 14:41:11'
  ]
]

Also, please check the documentation to know more about the map function.

For me the problem was a configuration file that was missing an Element.

std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();

This is a great place for auto:

auto now = std::chrono::system_clock::now();

Since you want to traffic at millisecond precision, it would be good to go ahead and covert to it in the time_point:

auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

now_ms is a time_point, based on system_clock, but with the precision of milliseconds instead of whatever precision your system_clock has.

auto epoch = now_ms.time_since_epoch();

epoch now has type std::chrono::milliseconds. And this next statement becomes essentially a no-op (simply makes a copy and does not make a conversion):

auto value = std::chrono::duration_cast<std::chrono::milliseconds>(epoch);

Here:

long duration = value.count();

In both your and my code, duration holds the number of milliseconds since the epoch of system_clock.

This:

std::chrono::duration<long> dur(duration);

Creates a duration represented with a long, and a precision of seconds. This effectively reinterpret_casts the milliseconds held in value to seconds. It is a logic error. The correct code would look like:

std::chrono::milliseconds dur(duration);

This line:

std::chrono::time_point<std::chrono::system_clock> dt(dur);

creates a time_point based on system_clock, with the capability of holding a precision to the system_clock's native precision (typically finer than milliseconds). However the run-time value will correctly reflect that an integral number of milliseconds are held (assuming my correction on the type of dur).

Even with the correction, this test will (nearly always) fail though:

if (dt != now)

Because dt holds an integral number of milliseconds, but now holds an integral number of ticks finer than a millisecond (e.g. microseconds or nanoseconds). Thus only on the rare chance that system_clock::now() returned an integral number of milliseconds would the test pass.

But you can instead:

if (dt != now_ms)

And you will now get your expected result reliably.

Putting it all together:

int main ()
{
    auto now = std::chrono::system_clock::now();
    auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    std::chrono::milliseconds dur(duration);

    std::chrono::time_point<std::chrono::system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Personally I find all the std::chrono overly verbose and so I would code it as:

int main ()
{
    using namespace std::chrono;
    auto now = system_clock::now();
    auto now_ms = time_point_cast<milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    milliseconds dur(duration);

    time_point<system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Which will reliably output:

Success.

Finally, I recommend eliminating temporaries to reduce the code converting between time_point and integral type to a minimum. These conversions are dangerous, and so the less code you write manipulating the bare integral type the better:

int main ()
{
    using namespace std::chrono;
    // Get current time with precision of milliseconds
    auto now = time_point_cast<milliseconds>(system_clock::now());
    // sys_milliseconds is type time_point<system_clock, milliseconds>
    using sys_milliseconds = decltype(now);
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    sys_milliseconds dt{milliseconds{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

The main danger above is not interpreting integral_duration as milliseconds on the way back to a time_point. One possible way to mitigate that risk is to write:

    sys_milliseconds dt{sys_milliseconds::duration{integral_duration}};

This reduces risk down to just making sure you use sys_milliseconds on the way out, and in the two places on the way back in.

And one more example: Let's say you want to convert to and from an integral which represents whatever duration system_clock supports (microseconds, 10^th of microseconds or nanoseconds). Then you don't have to worry about specifying milliseconds as above. The code simplifies to:

int main ()
{
    using namespace std::chrono;
    // Get current time with native precision
    auto now = system_clock::now();
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    system_clock::time_point dt{system_clock::duration{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

This works, but if you run half the conversion (out to integral) on one platform and the other half (in from integral) on another platform, you run the risk that system_clock::duration will have different precisions for the two conversions.

The full paramiko distribution ships with a lot of good demos.

In the demos subdirectory, demo.py and interactive.py have full interactive TTY examples which would probably be overkill for your situation.

In your example above ssh_stdin acts like a standard Python file object, so ssh_stdin.write should work so long as the channel is still open.

I've never needed to write to stdin, but the docs suggest that a channel is closed as soon as a command exits, so using the standard stdin.write method to send a password up probably won't work. There are lower level paramiko commands on the channel itself that give you more control - see how the SSHClient.exec_command method is implemented for all the gory details.

Option 1

If one doesn't know the sheets names

# Read all sheets in your File
df = pd.read_excel('FILENAME.xlsm', sheet_name=None)
    
# Prints all the sheets name in an ordered dictionary
print(df.keys())

Then, depending on the sheet one wants to read, one can pass each of them to a specific dataframe, such as

sheet1_df = pd.read_excel('FILENAME.xlsm', sheet_name=SHEET1NAME)
sheet2_df = pd.read_excel('FILENAME.xlsm', sheet_name=SHEET2NAME)

Option 2

If the name is not relevant and all one cares about is the position of the sheet. Let's say one wants only the first sheet,

# Read all sheets in your File
df = pd.read_excel('FILENAME.xlsm', sheet_name=None)

sheet1 = list(df.keys())[0]

Then, depending on the sheet name, one can pass each it to a specific dataframe, such as

sheet1_df = pd.read_excel('FILENAME.xlsm', sheet_name=SHEET1NAME)

Use:

git log --graph --abbrev-commit --decorate  --first-parent <branch_name>

It is only for the target branch (of course --graph, --abbrev-commit --decorate are more polishing).

The key option is --first-parent: "Follow only the first parent commit upon seeing a merge commit" (https://git-scm.com/docs/git-log)

It prevents the commit forks from being displayed.

Using seeds.rb file or FactoryBot is great, but these are respectively great for fixed data structures and testing.

The seedbank gem might give you more control and modularity to your seeds. It inserts rake tasks and you can also define dependencies between your seeds. Your rake task list will have these additions (e.g.):

rake db:seed                    # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/ENVIRONMENT/*.seeds.rb. ENVIRONMENT is the current environment in Rails.env.
rake db:seed:bar                # Load the seed data from db/seeds/bar.seeds.rb
rake db:seed:common             # Load the seed data from db/seeds.rb and db/seeds/*.seeds.rb.
rake db:seed:development        # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/development/*.seeds.rb.
rake db:seed:development:users  # Load the seed data from db/seeds/development/users.seeds.rb
rake db:seed:foo                # Load the seed data from db/seeds/foo.seeds.rb
rake db:seed:original           # Load the seed data from db/seeds.rb

I stumbled across this solution in the documentation for the Create Database statement in the help for SQL Server:

SELECT SUBSTRING(physical_name, 1, CHARINDEX(N'master.mdf', LOWER(physical_name)) - 1)
                  FROM master.sys.master_files
                  WHERE database_id = 1 AND file_id = 1

You could use substr.

str.substr(i).match(/[abc]/);

I recently bumped into the same problem. Tried to find a cheaper solution so came up with this.

   <LinearLayout
        android:id="@+id/linearButton"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/selector_button_translucent_ab_color"
        android:clickable="true"
        android:descendantFocusability="blocksDescendants"
        android:gravity="center"
        android:orientation="horizontal" >

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:contentDescription="@string/app_name"
            android:src="@drawable/ic_launcher" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/app_name"
            android:textColor="@android:color/white" />
    </LinearLayout>

Then just call the OnClickListener on LinearLayout.

Hope this helps someone as it seems like a very common problem. :)

You have mutual top-level imports, which is almost always a bad idea.

If you really must have mutual imports in Python, the way to do it is to import them within a function:

# In b.py:
def cause_a_to_do_something():
    import a
    a.do_something()

Now a.py can safely do import b without causing problems.

(At first glance it might appear that cause_a_to_do_something() would be hugely inefficient because it does an import every time you call it, but in fact the import work only gets done the first time. The second and subsequent times you import a module, it's a quick operation.)

One observation: (though this can be thought of side effect)

boolean being a primitive can either say yes or no.

Boolean is an object (it can refer to either yes or no or 'don't know' i.e. null)

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName
Set
Created="01/01/2000"
where Created is NULL
