You can use QString.arg like this

QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", "Jane");
// You get "~/Tom-Jane.txt"

This method is preferred over sprintf because:

Changing the position of the string without having to change the ordering of substitution, e.g.

// To get "~/Jane-Tom.txt"
QString my_formatted_string = QString("%1/%3-%2.txt").arg("~", "Tom", "Jane");

Or, changing the type of the arguments doesn't require changing the format string, e.g.

// To get "~/Tom-1.txt"
QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", QString::number(1));

As you can see, the change is minimal. Of course, you generally do not need to care about the type that is passed into QString::arg() since most types are correctly overloaded.

One drawback though: QString::arg() doesn't handle std::string. You will need to call: QString::fromStdString() on your std::string to make it into a QString before passing it to QString::arg(). Try to separate the classes that use QString from the classes that use std::string. Or if you can, switch to QString altogether.

That's an old thread, but in case you want to upload the image having same extension-

    $image = $request->image;
    $imageInfo = explode(";base64,", $image);
    $imgExt = str_replace('data:image/', '', $imageInfo[0]);      
    $image = str_replace(' ', '+', $imageInfo[1]);
    $imageName = "post-".time().".".$imgExt;
    Storage::disk('public_feeds')->put($imageName, base64_decode($image));

You can create 'public_feeds' in laravel's filesystem.php-

   'public_feeds' => [
        'driver' => 'local',
        'root'   => public_path() . '/uploads/feeds',
    ],

The downfall of ArrayList and LinkedList is that when iterating through them, depending on the search algorithm, the time it takes to find an item grows with the size of the list.

The beauty of hashing is that although you sacrifice some extra time searching for the element, the time taken does not grow with the size of the map. This is because the HashMap finds information by converting the element you are searching for, directly into the index, so it can make the jump.

Long story short... LinkedList: Consumes a little more memory than ArrayList, low cost for insertions(add & remove) ArrayList: Consumes low memory, but similar to LinkedList, and takes extra time to search when large. HashMap: Can perform a jump to the value, making the search time constant for large maps. Consumes more memory and takes longer to find the value than small lists.

create resource layout file list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="wrap_content">
<TextView
        android:id="@+id/header_text"
        android:layout_height="0dp"
        android:layout_width="fill_parent"
        android:layout_weight="1"
        android:text="Header"
        />
<TextView
        android:id="@+id/item_text"
        android:layout_height="0dp"
        android:layout_width="fill_parent"
        android:layout_weight="1"
        android:text="dynamic text"
        />
</LinearLayout>

and initialise adaptor like this

adapter = new ArrayAdapter<String>(this, R.layout.list_item,R.id.item_text,data_array);

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

Swift 3 solution:

let languages = ["bs", "zh-Hant", "en", "fi", "ko", "lv", "ms", "pl", "pt-BR", "ru", "sr-Latn", "sk", "es", "tr"]
UserDefaults.standard.set([languages[0]], forKey: "AppleLanguages")

Gave some examples of language codes that can be used. Hope this helps

An IEEE double has 53 significant bits (that's the value of DBL_MANT_DIG in <cfloat>). That's approximately 15.95 decimal digits (log10(2⁵³)); the implementation sets DBL_DIG to 15, not 16, because it has to round down. So you have nearly an extra decimal digit of precision (beyond what's implied by DBL_DIG==15) because of that.

The nextafter() function computes the nearest representable number to a given number; it can be used to show just how precise a given number is.

This program:

#include <cstdio>
#include <cfloat>
#include <cmath>

int main() {
    double x = 1.0/7.0;
    printf("FLT_RADIX = %d\n", FLT_RADIX);
    printf("DBL_DIG = %d\n", DBL_DIG);
    printf("DBL_MANT_DIG = %d\n", DBL_MANT_DIG);
    printf("%.17g\n%.17g\n%.17g\n", nextafter(x, 0.0), x, nextafter(x, 1.0));
}

gives me this output on my system:

FLT_RADIX = 2
DBL_DIG = 15
DBL_MANT_DIG = 53
0.14285714285714282
0.14285714285714285
0.14285714285714288

(You can replace %.17g by, say, %.64g to see more digits, none of which are significant.)

As you can see, the last displayed decimal digit changes by 3 with each consecutive value. The fact that the last displayed digit of 1.0/7.0 (5) happens to match the mathematical value is largely coincidental; it was a lucky guess. And the correct rounded digit is 6, not 5. Replacing 1.0/7.0 by 1.0/3.0 gives this output:

FLT_RADIX = 2
DBL_DIG = 15
DBL_MANT_DIG = 53
0.33333333333333326
0.33333333333333331
0.33333333333333337

which shows about 16 decimal digits of precision, as you'd expect.

I had the same question and solved the problem. In my case, the Windows Firewall (not the router) was blocking the V8 machine I/O on the hosting machine.

1. Go to windows button
2. Search "Firewall"
3. Choose "Allow programs to communicate through Firewall"
4. Click Change Setup
5. Tick all of "Evented I/O for V8 Javascript" OR "Node.js: Server-side Javascript"

My guess is that "Evented I/O for V8 Javascript" is the I/O process that node.js communicates to outside world and we need to free it before it can send packets outside of the local computer. After enabling this program to communicate over Windows firewall, I could use any port numbers to listen.

All too often a new developer asks this simple question which is a common problem specifically with Visual Studio IDE's. Few people answer the specific question and often critique the question or give "guesses" for solutions which don't answer the common problems. The first common problem is the IDE leads you to create new projects rather than add new files (.java, .py, .cpp, .c) to the existing solution (by default it creates a new solution) unless you change the project name and add to the current solution. This problem occurs for Python, java, c#, C++ and C project folders.

The new developer selecting "new>project>project name and changing the solution directory to "use same solution" still creates a new "project" in the same solution space, but not in the same directory space as the current user interface file or command line file which still leads to problems with "package not found" errors when building and running the project or solution. This is why the above coding suggestions to importing packages, classes, methods and functions only work (and thus don't answer the question) when the "library" file or "separate behavior" file is not only in the same solution directory path, but also in the same "user interface" or "command shell" application directory space. This does does not happen when you add another project using the new>project>project type commands of the IDE. The problem here is the new project is stored in a different directory than the existing Client or User interface code files. To create a new "file" in the same project space rather than new project the beginner needs to do the following that Microsoft won't do for you and even misleads you away from the intuitively obvious by default.

1. Select the "application" you want to import the new behavior into (from another file)
2. Select project>add new item
3. Select the "program file template type" such as filetype.py, filetype.java, filetype.c, filetype.cpp, filetype.C#, etc. or a library class file type (something other than startup file options you see when you create a new application project or create a new library project).
4. A new file name with default name is created in your project.
5. Change the default name of the file to something like library.py or façade.java, etc.

NOW the code recommendations to import libraries or using namespaces will work as described in the comments above and you don't have to change path statements or change solutions paths and solution names that Microsoft won't let you change easily (i.e. you can change the filenames or project names but the IDE won't automatically change the project path or the solution path names).

The following is a Python example but works similar for C#, java, or C/C++ using the includes, namespaces or using code commands appropriate to each language to find code in other classes/projects in the SAME DIRECTORY SPACE.

The application file "hello world" importing from other code files in the same directory.

Note the python white space delimiters are not going to space correctly in this stackoverflow comment editor:

print ("test")

from CIXMPythonFacade import ClassA

c1=ClassA
c1.methodA()

from CIXMPythonFacade import functionA 

functionA()


class ClassName(object): 
         def __init__(object, parameter):
         object.parameter = value

The library file or "façade" file containing classes, methods or functions you want to import.

class class1(object):
    """description of class"""

class ClassA(object):
    print ("test2")
    def methodA():
        print ("test3")

def functionA ():
    print ("test4")
    return (0)


pass

NOW how do you actually solve the mess that the IDE leads you into? To import code from another file in the same directory space you add a reference to it.

1. Select the application file
2. Select Project>add reference
3. Choose the filename visible with the right directory path (check it)
4. The reference is now available to the interpreter, the code checker and/or the compiler.

OK so now that you have this problem solved, how do you really link two separate projects together in the same solution space?

1. You have to go to both the indexer or "intellisense" options and the compiler/interpreter and physically check or change/add the directory path statements if they are something other than what points to your "second" project or solution space. When you do the path changes or change the path variables to your workspace and to the specific locations of the projects which are different directory spaces the compiler and the code analyzer can then find these libraries, headers.h, namespaces, project or file locations.
2. To remove old projects you created by mistake it is even worse. You have to exit the Visual Studio IDE, open windows explorer, go to the workspace directory ...documents\visualstudio xxx\solutionname\packagename select the file or folder, right click and "delete" file or folder.
3. When you re-enter the IDE and select open solution or open package/solution, the old files and solution/package names are gone as are their misleading path statements which fools the compiler and code analyzer to look at the old directory even though you changed the filename and changed the project name, it does not change the directory path with it.

Microsoft really, really needs to fix these problem so you can intuitively create what most people want to create as new files in the same directories and remove solutions by selecting them and deleting them from the IDE. Beginners get so frustrated with directory path statements so flexible for seasoned developers, but so unfair to new developers in their defaults.

Hope this really helps you new guys and stops seasoned developers from giving you the wrong answers that don't work for you. They assume you already understand path statements and just want to type the right code...which is also why the tunnel in on trying to correct your code but does not help you fix the problem. This is probably the most common problem continually described on stackoverflow with wrong answers that don't work for new programmers.

For a super succinct with jQuery approach try:

<div onclick="$(this).toggleClass('newclass')">click me</div>

Or pure JS:

<div onclick="this.classList.toggle('newclass');">click me</div>

You can use twitter search page to bypass 3,200 limit. However you have to scroll down many times in the search results page. For example, I searched tweets from @beyinsiz_adam. This is the link of search results: https://twitter.com/search?q=from%3Abeyinsiz_adam&src=typd&f=realtime

Now in order to scroll down many times, you can use the following javascript code.

    var myVar=setInterval(function(){myTimer()},1000);
    function myTimer() {
        window.scrollTo(0,document.body.scrollHeight);
    }

Just run it in the FireBug console. And wait some time to load all tweets.

The best option I found is below. It will extract a number and can eliminate any type of char.

def extract_nbr(input_str):
    if input_str is None or input_str == '':
        return 0

    out_number = ''
    for ele in input_str:
        if ele.isdigit():
            out_number += ele
    return float(out_number)    

DO NOT PUT .xib WHEN YOU INSERT IN THE XIB NAME! IT IS ALREADY IMPLIED!

Dont do this:

 UIView *viewFromNib = [[NSBundle mainBundle] loadNibNamed:@"ResultsAssessmentView.xib" owner:self options:nil][0];

Do this:

 UIView *viewFromNib = [[NSBundle mainBundle] loadNibNamed:@"ResultsAssessmentView" owner:self options:nil][0];

One thing that has worked for me with random npm install errors (where the package that errors out is different under different times (but same environment) is to use this:

npm cache clean

And then repeat the process. Then the process seems to go smoother and the real problem and error message will emerge, where you can fix it and then proceed.

This is based on experience of running npm install of a whole bunch of packages under a pretty bare Ubuntu installation inside a Docker instance. Sometimes there are build/make tools missing from the Ubuntu and the npm errors will not show the real problem until you clean the cache for some reason.

This java program help to find second highest number in any given array. First we have to get highest value and then we have to go second one.

class Demo{
    public static void main(String args[]){
        int arr[]={321,321,321,43,65,234,56,-1,4,45,-67};
        int max=arr[0];
        int len=arr.length;
        for(int i=0;i<len;i++){
            if(max<arr[i]){
                max=arr[i];
            }
        }

        System.out.println("Max value is "+max);

        int secMax=arr[0];
        for(int j=0;j<len;j++){
            if(max>arr[j]){
                if(secMax<arr[j]){
                    secMax=arr[j];
                }
                else if(secMax>arr[j]){
                    secMax=arr[j];
                }

            }
            else if(max==arr[j]){
                //
            }

        }
                System.out.println("Sec Max value is "+secMax);

    }
}

Remove the ' around the point:

mysql_query("UPDATE member_profile SET points=".$points."+1 WHERE user_id = '".$userid."'");

You are "casting" an integer value to string in your original query...

From the official documentation regarding the Formatter class:

The constructor takes two optional arguments: a message format string and a date format string.

So change

# create formatter
formatter = logging.Formatter("%(asctime)s;%(levelname)s;%(message)s")

to

# create formatter
formatter = logging.Formatter("%(asctime)s;%(levelname)s;%(message)s",
                              "%Y-%m-%d %H:%M:%S")

var a = A.parentNode.replaceChild(document.createElement("span"), A);

a is the replaced A element.

Hope this will help you. Please let me know If you have any query.

assert() is not a native javascript function. It is a custom function someone made. You will have to look for it on your page or in your files and post it for anybody to help determine what it's doing.

For checking Java version in android studio version , simply open Terminal of Android Studio and type

java -version 

This will display java version installed in android studio

Finally it worked for me.

<select ng-init="mybasketModel = basket[0]" ng-model="mybasketModel">
        <option ng-repeat="item in basket" ng-selected="$first">{{item}}</option>
</select>

Integer.parseInt(str) throws NumberFormatException if the string does not contain a parsable integer. You can hadle the same as below.

int a;
String str = "N/A";

try {   
   a = Integer.parseInt(str);
} catch (NumberFormatException nfe) {
  // Handle the condition when str is not a number.
}

Here's an example of going from a list of strings, to a single string, back to a list of strings.

Compiling:

$ javac test.java
$ java test

Running:

    Initial list:

        "abc"
        "def"
        "ghi"
        "jkl"
        "mno"

    As single string:

        "[abc, def, ghi, jkl, mno]"

    Reconstituted list:

        "abc"
        "def"
        "ghi"
        "jkl"
        "mno"

Source code:

import java.util.*;
public class test {

    public static void main(String[] args) {
        List<String> listOfStrings= new ArrayList<>();
        listOfStrings.add("abc");
        listOfStrings.add("def");
        listOfStrings.add("ghi");
        listOfStrings.add("jkl");
        listOfStrings.add("mno");

        show("\nInitial list:", listOfStrings);

        String singleString = listOfStrings.toString();

        show("As single string:", singleString);

        List<String> reconstitutedList = Arrays.asList(
             singleString.substring(0, singleString.length() - 1)
                  .substring(1).split("[\\s,]+"));

        show("Reconstituted list:", reconstitutedList);
    }

    public static void show(String title, Object operand) {
        System.out.println(title + "\n");
        if (operand instanceof String) {
            System.out.println("    \"" + operand + "\"");
        } else {
            for (String string : (List<String>)operand)
                System.out.println("    \"" + string + "\"");
        }
        System.out.println("\n");
    }
}

I've required this functionality several times for debugging/analyzing code from others. For this, I've written a Perl script which generates a class with several overloaded toString methods. Each toString method takes an Enum as an argument and returns const char*.

Of course, the script doesn't parse C++ for enums itself, but uses ctags for generating symbol table.

The Perl script is here: http://heinitz-it.de/download/enum2string/enum2string.pl.html

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

You don't. The whole reason for using the SecureString object is to avoid creating a string object (which is loaded into memory and kept there in plaintext until garbage collection). However, you can add characters to a SecureString by appending them.

var s = new SecureString();
s.AppendChar('d');
s.AppendChar('u');
s.AppendChar('m');
s.AppendChar('b');
s.AppendChar('p');
s.AppendChar('a');
s.AppendChar('s');
s.AppendChar('s');
s.AppendChar('w');
s.AppendChar('d');

Double quotes are interpreted as literals in regex; they are not special characters. You are trying to match a literal "||".

Just use Pattern.quote(delimiter):

As requested, here's a line of code (same as Sanjay's)

final String[] tokens = line.split(Pattern.quote(delimiter));

If that doesn't work, you're not passing in the correct delimiter.

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

When you want to write more complex ruby scripts, these tools may help:

For example:

• thor(a scripting framework)

• gli(git like interface)

• methadone(for creating simple tools)

They give you a quick start to write your own scripts, especially 'command line app'.

Also if your variable is an ARRAY, there are few options too:

{% if arrayVariable[0] is defined %} 
    #if variable is not null#
{% endif %}

OR

{% if arrayVariable|length > 0 %} 
    #if variable is not null# 
{% endif %}

This will only works if your array is defined AND is NULL

Don't name your current python script with the name of some other module you import

Solution: rename your working python script

Example:

1. you are working in medicaltorch.py
2. in that script, you have: from medicaltorch import datasets as mt_datasets where medicaltorch is supposed to be an installed module

This will fail with the ImportError. Just rename your working python script in 1.

You can use "wildcards" with MATCH so assuming "ASDFGHJK" in H1 as per Peter's reply you can use this regular formula

=INDEX(G:G,MATCH("*"&H1&"*",G:G,0)+3)

MATCH can only reference a single column or row so if you want to search 6 columns you either have to set up a formula with 6 MATCH functions or change to another approach - try this "array formula", assuming search data in A2:G100

=INDIRECT("R"&REPLACE(TEXT(MIN(IF(ISNUMBER(SEARCH(H1,A2:G100)),(ROW(A2:G100)+3)*1000+COLUMN(A2:G100))),"000000"),4,0,"C"),FALSE)

confirmed with Ctrl-Shift-Enter

If the undefined's are implicit then you can do:

var len = 0;
for (var i in arr) { len++ };

undefined's are implicit if you don't set them explicitly

//both are a[0] and a[3] are explicit undefined
var arr = [undefined, 1, 2, undefined];

arr[6] = 3;
//now arr[4] and arr[5] are implicit undefined

delete arr[1]
//now arr[1] is implicit undefined

arr[2] = undefined
//now arr[2] is explicit undefined

Only this sample working without problem:

var crop = new Rectangle(0, y, bitmap.Width, h);
var bmp = new Bitmap(bitmap.Width, h);
var tempfile = Application.StartupPath+"\\"+"TEMP"+"\\"+Path.GetRandomFileName();


using (var gr = Graphics.FromImage(bmp))
{
    try
    {
        var dest = new Rectangle(0, 0, bitmap.Width, h);
        gr.DrawImage(image,dest , crop, GraphicsUnit.Point);
        bmp.Save(tempfile,ImageFormat.Jpeg);
        bmp.Dispose();
    }
    catch (Exception)
    {


    }

}

This might be an exception occurring in the finalizer. If you are doing the Pattern of ~Class(){ Dispose(false); } check what are you disposing as an un-managed resource. Just put a try..catch there and you should be fine.

We found the issue as we had this mysterious failure with no logs We did the usual recommended pattern of using a "void Dispose(bool disposing)".

Looking at the answers on this question about the finalizer we found a possible place where the Disposal of the unmanaged resources could throw an exception.

It turns out somewhere we did not dispose the object properly thus the finalizer took over the diposal of unmanaged resources thus behold an exception occurred.

In this case was using the Kafka Rest API to clean up the client from Kafka. Seems that it did threw exception at some point then this issue occurred.

Shouldnt we be using OG?

The chosen answer is good but doesn't work when a site is redirected (very common!), and doesn't return OG tags, which are the new industry standard. Here's a little function which is a bit more usable in 2018. It tries to get OG tags and falls back to meta tags if it cant them:

function getSiteOG( $url, $specificTags=0 ){
    $doc = new DOMDocument();
    @$doc->loadHTML(file_get_contents($url));
    $res['title'] = $doc->getElementsByTagName('title')->item(0)->nodeValue;

    foreach ($doc->getElementsByTagName('meta') as $m){
        $tag = $m->getAttribute('name') ?: $m->getAttribute('property');
        if(in_array($tag,['description','keywords']) || strpos($tag,'og:')===0) $res[str_replace('og:','',$tag)] = $m->getAttribute('content');
    }

You could run some jQuery client-side validation to check:

$(function(){
    $("input[type='submit']").click(function(){
        var $fileUpload = $("input[type='file']");
        if (parseInt($fileUpload.get(0).files.length)>2){
         alert("You can only upload a maximum of 2 files");
        }
    });    
});?

But remember to check on the server side too as client-side validation can be bypassed quite easily.

You can unhide navigationController in viewWillDisappear

override func viewWillDisappear(animated: Bool)
{
    super.viewWillDisappear(animated)
    self.navigationController?.isNavigationBarHidden = false
}

Swift 3

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    self.navigationController?.setNavigationBarHidden(false, animated: animated)
}

to check your node verison right. using NODE_MODULE_VERSION 51 means that your node version is nodejs v7.x, requires NODE_MODULE_VERSION 57 means you need upgrade your node to v8.x,so you need to upgrade your node. and then you need run npm rebuild command to rebuild your project

A concrete example of overhead is the difference between a "local" procedure call and a "remote" procedure call.

For example, with classic RPC (and many other remote frameworks, like EJB), a function or method call looks the same to a coder whether its a local, in memory call, or a distributed, network call.

For example:

service.function(param1, param2);

Is that a normal method, or a remote method? From what you see here you can't tell.

But you can imagine that the difference in execution times between the two calls are dramatic.

So, while the core implementation will "cost the same", the "overhead" involved is quite different.

When using a widget like jQuery UI's Autocomplete make sure to check that it is not adding/changing to autocomplete attribute to off. I found this to be true when using it and will break any work you may have done to override any browser field caching. Make certain that you have a unique name attribute and force a unique autocomplete attribute after the widget initializes. See below for some hints on how that might work for your situation.

<?php $autocomplete = 'off_'.time(); ?>
<script>
   $('#email').autocomplete({
      create: function( event, ui ) {
         $(this).attr('autocomplete','<? echo $autocomplete; ?>');
      },
      source: function (request, response) { //your code here },
      focus: function( event, ui ) { //your code here },
      select: function( event, ui ) { //your code here },
   });
</script>
<input type="email" id="email" name="email_<? echo $autocomplete; ?>" autocomplete="<? echo $autocomplete; ?>" />

In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,

default_days     = 1000         # How long to certify for

defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:

openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.

Perhaps the most ignorant answer I've posted but here goes: Use TigerVNC client/viewer and check 'Resize remote session to local window' under Screen tab of options.

I don't know what the $%#@ TigerVNC client tells remote vncserver or xrandr or Xvnc or gnome or ... but it resizes when I change the TigerVNC Client window.

My setup:

• Tiger VNC Server running on CentOS 6. Hosting GNOME desktop. (Works with RHEL 6.6 too)
• Windows some version with Tiger VNC Client.

With this the resolution changes to fit the size of the client window no matter what it is, and it's not zooming, it's actual resolution change (I can see the new resolution in xrandr output).

I tried all I could to add a new resolution to the xrandr, but to no avail, always end up with 'xrandr: Failed to get size of gamma for output default' error.

Versions with which it works for me right now (although I've not had issues with ANY versions in the past, I just install the latest using yum install gnome-* tigervnc-server and works fine):

Following is a succinct implementation using Java8 streams, a one liner:

String foobarspam = "foobarspam";
AtomicInteger splitCounter = new AtomicInteger(0);
Collection<String> splittedStrings = foobarspam
                                    .chars()
                                    .mapToObj(_char -> String.valueOf((char)_char))
                                    .collect(Collectors.groupingBy(stringChar -> splitCounter.getAndIncrement() / 3
                                                                ,Collectors.joining()))
                                    .values();

Output:

[foo, bar, spa, m]

<img id="output_image" height=50px width=50px\
<input type="file" accept="image/*" onchange="preview_image(event)">

<script type"text/javascript">
  function preview_image(event) {
    var reader = new FileReader();
    reader.onload = function(){
      var output = document.getElementById('output_image');
      output.src = reader.result;
    }
    reader.readAsDataURL(event.target.files[0]);

Method 1: Wrap Label Tag

Wrap the checkbox within a label tag:

<label><input type="checkbox" name="checkbox" value="value">Text</label>

Method 2: Use the for Attribute

Use the for attribute (match the checkbox id):

<input type="checkbox" name="checkbox" id="checkbox_id" value="value">
<label for="checkbox_id">Text</label>

NOTE: ID must be unique on the page!

Explanation

Since the other answers don't mention it, a label can include up to 1 input and omit the for attribute, and it will be assumed that it is for the input within it.

Excerpt from w3.org (with my emphasis):

[The for attribute] explicitly associates the label being defined with another control. When present, the value of this attribute must be the same as the value of the id attribute of some other control in the same document. When absent, the label being defined is associated with the element's contents.

To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element. The label itself may be positioned before or after the associated control.

Using this method has some advantages over for:

• No need to assign an id to every checkbox (great!).

• No need to use the extra attribute in the <label>.

• The input's clickable area is also the label's clickable area, so there aren't two separate places to click that can control the checkbox - only one, no matter how far apart the <input> and actual label text are, and no matter what kind of CSS you apply to it.

Demo with some CSS:

label {
 border:1px solid #ccc;
 padding:10px;
 margin:0 0 10px;
 display:block; 
}

label:hover {
 background:#eee;
 cursor:pointer;
}

<label><input type="checkbox" />Option 1</label>
<label><input type="checkbox" />Option 2</label>
<label><input type="checkbox" />Option 3</label>

is called a generic type. You can instantiate an object Pool like this:

PoolFactory<Integer> pool = new Pool<Integer>();

The generic parameter can only be a reference type. So you can't use primitive types like int or double or char or other primitive types.

Yes, you can definitely do this. Just use something like

.parent:hover .child {
   /* ... */
}

According to this page it's supported by all major browsers.

This error occurs because you tell to Maven to pakage files to war.

<packaging>war</packaging>

Do you really need war? If not, put jar there. Here is full code:

// or in C# 3.0:
var foos = dict.Values.ToArray();

To answer your first question... .format just seems more sophisticated in many ways. An annoying thing about % is also how it can either take a variable or a tuple. You'd think the following would always work:

"hi there %s" % name

yet, if name happens to be (1, 2, 3), it will throw a TypeError. To guarantee that it always prints, you'd need to do

"hi there %s" % (name,)   # supply the single argument as a single-item tuple

which is just ugly. .format doesn't have those issues. Also in the second example you gave, the .format example is much cleaner looking.

Why would you not use it?

• not knowing about it (me before reading this)
• having to be compatible with Python 2.5

To answer your second question, string formatting happens at the same time as any other operation - when the string formatting expression is evaluated. And Python, not being a lazy language, evaluates expressions before calling functions, so in your log.debug example, the expression "some debug info: %s"%some_infowill first evaluate to, e.g. "some debug info: roflcopters are active", then that string will be passed to log.debug().

redirect to ../

You have a couple options, you could setTimeout() or setInterval(). Here's a great article that elaborates on how to use them.

The magic is that they're built in to JavaScript, you can use them with any library.

Try this:

your_command 2>stderr.log 1>stdout.log

More information

The numerals 0 through 9 are file descriptors in bash. 0 stands for standard input, 1 stands for standard output, 2 stands for standard error. 3 through 9 are spare for any other temporary usage.

Any file descriptor can be redirected to a file or to another file descriptor using the operator >. You can instead use the operator >> to appends to a file instead of creating an empty one.

Usage:

file_descriptor > filename

file_descriptor > &file_descriptor

Please refer to Advanced Bash-Scripting Guide: Chapter 20. I/O Redirection.

Please use this for comparison:

string.Equals(a, b, StringComparison.CurrentCultureIgnoreCase);

std::string trimmed(std::string str ) {
if(str.length() == 0 ) { return "" ; }
else if ( str == std::string(" ") ) { return "" ; } 
else {
    while(str.at(0) == ' ') { str.erase(0, 1);}
    while(str.at(str.length()-1) == ' ') { str.pop_back() ; }
    return str ;
    } 
}

add this code to the starting of the main CSS.

*,html,body{
  margin:0 !important;
  padding:0 !important;
  box-sizing: border-box !important;;
}

This might work for you...

<script type="text/javascript">

All the above answers are correct. Just providing with your dataset to find perfect divisor:

#include <stdio.h>

int main() 
{

int arr[7] = {3,5,7,8,9,17,19};
int j = 51;
int i = 0;

for (i=0 ; i < 7; i++) {
    if (j % arr[i] == 0)
        printf("%d is the perfect divisor of %d\n", arr[i], j);
}

return 0;
}

Use the command:

git rev-parse HEAD

For the short version:

git rev-parse --short HEAD

There are mainly three types of variables in MySQL:

1. User-defined variables (prefixed with @):

   You can access any user-defined variable without declaring it or initializing it. If you refer to a variable that has not been initialized, it has a value of NULL and a type of string.

   SELECT @var_any_var_name
   

   You can initialize a variable using SET or SELECT statement:

   SET @start = 1, @finish = 10;    
   

   or

   SELECT @start := 1, @finish := 10;
   
   SELECT * FROM places WHERE place BETWEEN @start AND @finish;
   

   User variables can be assigned a value from a limited set of data types: integer, decimal, floating-point, binary or nonbinary string, or NULL value.

   User-defined variables are session-specific. That is, a user variable defined by one client cannot be seen or used by other clients.

   They can be used in SELECT queries using Advanced MySQL user variable techniques.

2. Local Variables (no prefix) :

   Local variables needs to be declared using DECLARE before accessing it.

   They can be used as local variables and the input parameters inside a stored procedure:

   DELIMITER //
   
   CREATE PROCEDURE sp_test(var1 INT) 
   BEGIN   
       DECLARE start  INT unsigned DEFAULT 1;  
       DECLARE finish INT unsigned DEFAULT 10;
   
       SELECT  var1, start, finish;
   
       SELECT * FROM places WHERE place BETWEEN start AND finish; 
   END; //
   
   DELIMITER ;
   
   CALL sp_test(5);
   

   If the DEFAULT clause is missing, the initial value is NULL.

   The scope of a local variable is the BEGIN ... END block within which it is declared.

3. Server System Variables (prefixed with @@):

   The MySQL server maintains many system variables configured to a default value. They can be of type GLOBAL, SESSION or BOTH.

   Global variables affect the overall operation of the server whereas session variables affect its operation for individual client connections.

   To see the current values used by a running server, use the SHOW VARIABLES statement or SELECT @@var_name.

   SHOW VARIABLES LIKE '%wait_timeout%';
   
   SELECT @@sort_buffer_size;
   

   They can be set at server startup using options on the command line or in an option file. Most of them can be changed dynamically while the server is running using SET GLOBAL or SET SESSION:

   -- Syntax to Set value to a Global variable:
   SET GLOBAL sort_buffer_size=1000000;
   SET @@global.sort_buffer_size=1000000;
   
   -- Syntax to Set value to a Session variable:
   SET sort_buffer_size=1000000;
   SET SESSION sort_buffer_size=1000000;
   SET @@sort_buffer_size=1000000;
   SET @@local.sort_buffer_size=10000;
   

The <select> tag creates a dropdown list. You can't put html links inside a dropdown.

However, there are JavaScript libraries that provide similar functionality. Here is one example: http://www.dynamicdrive.com/dynamicindex1/dropmenuindex.htm

How can I get the item name "Mon, Tue, etc" when I already have the item value "0, 1, etc."

On some older C code (quite some time ago), I found code analogous to:

std::string weekEnumToStr(int n)
{
   std::string s("unknown");
   switch (n)
   {
   case 0: { s = "Mon"; } break;
   case 1: { s = "Tue"; } break;
   case 2: { s = "Wed"; } break;
   case 3: { s = "Thu"; } break;
   case 4: { s = "Fri"; } break;
   case 5: { s = "Sat"; } break;
   case 6: { s = "Sun"; } break;
   }
   return s;
}

Con: This establishes a "pathological dependency" between the enumeration values and the function... meaning if you change the enum you must change the function to match. I suppose this is true even for a std::map.

I vaguely remember we found a utility to generate the function code from the enum code. The enum table length had grown to several hundred ... and at some point it is maybe a sound choice to write code to write code.

Note -

in an embedded system enhancement effort, my team replaced many tables (100+?) of null-terminated-strings used to map enum int values to their text strings.

The problem with the tables was that a value out of range was often not noticed because many of these tables were gathered into one region of code / memory, such that a value out-of-range reached past the named table end(s) and returned a null-terminated-string from some subsequent table.

Using the function-with-switch statement also allowed us to add an assert in the default clause of the switch. The asserts found several more coding errors during test, and our asserts were tied into a static-ram-system-log our field techs could search.

If you want to listen to a native event on the root element of a component, you have to use the .native modifier for v-on, like following:

<template>
  <div id="app">
    <test v-on:click.native="testFunction"></test>
  </div>
</template>

or in shorthand, as suggested in comment, you can as well do:

<template>
  <div id="app">
    <test @click.native="testFunction"></test>
  </div>
</template>

Expanding on @Avenir Çokaj's answer

Being a novice even I did not understand the error message clearly at first.

What the error message indicates is that in your formGroup you have an element that doesn't get accounted for in your formControl. (Intentionally/Accidentally)

If you intend on not validating this field but still want to use the ngModel on this input element please add the flag to indicate it's a standalone component without a need for validation as mentioned by @Avenir above.

For other language use day of week to recognize day name

For example for Persian use below code

$dayName = getDayName(date('w', strtotime('2019-11-14')));

    function getDayName($dayOfWeek) {

        switch ($dayOfWeek){
            case 6:
                return '????';
            case 0:
                return '?? ????';
            case 1:
                return '?? ????';
            case 2:
                return '?? ????';
            case 3:
                return '???? ????';
            case 4:
                return '??? ????';
            case 5:
                return '????';
            default:
                return '';
        }

    }

Remove the z-index value.

I would also recommend this approach.

HTML:

<header class="main-header" role="banner">
  <img src="mybannerimage.gif" alt="Banner Image"/>
</header>

CSS:

.main-header {
  text-align: center;
}

This will center your image with out stretching it out. You can adjust the padding as needed to give it some space around your image. Since this is at the top of your page you don't need to force it there with position absolute unless you want your other elements to go underneath it. In that case you'd probably want position:fixed; anyway.

For Googlers:

• DO NOT mix statefulness with state transfer mechanisms

STATEFULNESS

• Stateful = save authorization info on server side, this is the traditional way
• Stateless = save authorization info on client side, along with a signature to ensure integrity

MECHANISMS

• Cookie = a special header with special treatment (access, storage, expiration, security, auto-transfer) by browsers
• Custom Headers = e.g. Authorization, are just headers without any special treatment, client has to manage all aspects of the transfer
• Other. Other transfer mechanisms may be utilized, e.g. query string was a choice to transfer auth ID for a while but was abandoned for its insecurity

STATEFULNESS COMPARISON

• "Stateful authorization" means the server stores and maintains user authorization info on server, making authorizations part of the application state
• This means client only need to keep an "auth ID" and the server can read auth detail from its database
• This implies that server keeps a pool of active auths (users that are logged in) and will query this info for every request
• "Stateless authorization" means the server does not store and maintain user auth info, it simply does not know which users are signed in, and rely on the client to produce auth info
• Client will store complete auth info like who you are (user ID), and possibly permissions, expiration time, etc., this is more than just auth ID, so it is given a new name token
• Obviously client cannot be trusted, so auth data is stored along with a signature generated from hash(data + secret key), where secret key is only known to server, so the integrity of token data can be verified
• Note that token mechanism merely ensures integrity, but not confidentiality, client has to implement that
• This also means for every request client has to submit a complete token, which incurs extra bandwidth

MECHANISM COMPARISON

• "Cookie" is just a header, but with some preloaded operations on browsers
• Cookie can be set by server and auto-saved by client, and will auto-send for same domain
• Cookie can be marked as httpOnly thus prevent client JavaScript access
• Preloaded operations may not be available on platforms other than browsers (e.g. mobile), which may lead to extra efforts
• "Custom headers" are just custom headers without preloaded operations
• Client is responsible to receive, store, secure, submit and update the custom header section for each requests, this may help prevent some simple malicious URL embedding

SUM-UP

• There is no magic, auth state has to be stored somewhere, either at server or client
• You may implement stateful/stateless with either cookie or other custom headers
• When people talk about those things their default mindset is mostly: stateless = token + custom header, stateful = auth ID + cookie; these are NOT the only possible options
• They have pros and cons, but even for encrypted tokens you should not store sensitive info

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

Return successfully by blocking rm's returncode behind a pipe with the true command, which always returns 0 (success)

The other answers were not completely satisfying to me. Here's what worked for postgresql-9.1 on Xubuntu 12.04.1 LTS.

1. Connect to the default database with user postgres:

   sudo -u postgres psql template1

2. Set the password for user postgres, then exit psql (Ctrl-D):

   ALTER USER postgres with encrypted password 'xxxxxxx';

3. Edit the pg_hba.conf file:

   sudo vim /etc/postgresql/9.1/main/pg_hba.conf

   and change "peer" to "md5" on the line concerning postgres:

   local      all     postgres     peer md5

   To know what version of postgresql you are running, look for the version folder under /etc/postgresql. Also, you can use Nano or other editor instead of VIM.

4. Restart the database :

   sudo /etc/init.d/postgresql restart

   (Here you can check if it worked with psql -U postgres).

5. Create a user having the same name as you (to find it, you can type whoami):

   sudo createuser -U postgres -d -e -E -l -P -r -s <my_name>

   The options tell postgresql to create a user that can login, create databases, create new roles, is a superuser, and will have an encrypted password. The really important ones are -P -E, so that you're asked to type the password that will be encrypted, and -d so that you can do a createdb.

   Beware of passwords: it will first ask you twice the new password (for the new user), repeated, and then once the postgres password (the one specified on step 2).

6. Again, edit the pg_hba.conf file (see step 3 above), and change "peer" to "md5" on the line concerning "all" other users:

   local      all     all     peer md5

7. Restart (like in step 4), and check that you can login without -U postgres:

   psql template1

   Note that if you do a mere psql, it will fail since it will try to connect you to a default database having the same name as you (i.e. whoami). template1 is the admin database that is here from the start.

8. Now createdb <dbname> should work.

I faced similar problem, The reason for it was i make use of ajax to fetch data. In this case i had made two asynchronous ajax call. In one i just return string msg and show in alert. In second ajax call i fetch arraylist in json format and decode it in js. So my second request use to process first and i was getting alert of object.

So just check. 1. alert should contain string. 2. If u get arrayList or any other Object decode it.

All the best!

Here is a function I use to execute sql commands. You just have to change $sqlCommand.CommandText to the name of your sproc and $SqlCommand.CommandType to CommandType.StoredProcedure.

function execute-Sql{
    param($server, $db, $sql )
    $sqlConnection = new-object System.Data.SqlClient.SqlConnection
    $sqlConnection.ConnectionString = 'server=' + $server + ';integrated security=TRUE;database=' + $db 
    $sqlConnection.Open()
    $sqlCommand = new-object System.Data.SqlClient.SqlCommand
    $sqlCommand.CommandTimeout = 120
    $sqlCommand.Connection = $sqlConnection
    $sqlCommand.CommandText= $sql
    $text = $sql.Substring(0, 50)
    Write-Progress -Activity "Executing SQL" -Status "Executing SQL => $text..."
    Write-Host "Executing SQL => $text..."
    $result = $sqlCommand.ExecuteNonQuery()
    $sqlConnection.Close()
}

You can install miniconda (https://conda.io/miniconda.html). That's a bit more than just python 3.7 but the installation is very straightforward and simple.

curl https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O
sudo yum install bzip2
bash Miniconda3-latest-Linux-x86_64.sh

You'll have to accept the license agreement and choose some options in interactive mode (accept the defaults). I believe it can be also installed silently somehow.

That's work for me. Where myList is some unknown kind of list.

IEnumerable myEnum = myList as IEnumerable;
Type entryType = myEnum.AsQueryable().ElementType;

In Python 3.4 you can use the pathlib module:

>>> from pathlib import Path
>>> p = Path('C:\Program Files\Internet Explorer\iexplore.exe')
>>> p.name
'iexplore.exe'
>>> p.suffix
'.exe'
>>> p.root
'\\'
>>> p.parts
('C:\\', 'Program Files', 'Internet Explorer', 'iexplore.exe')
>>> p.relative_to('C:\Program Files')
WindowsPath('Internet Explorer/iexplore.exe')
>>> p.exists()
True

While searching this very question I discovered this example in the documentation.

QPushButton *quitButton = new QPushButton("Quit");
connect(quitButton, &QPushButton::clicked, &app, &QCoreApplication::quit, Qt::QueuedConnection);

Mutatis mutandis for your particular action of course.

Along with this note.

It's good practice to always connect signals to this slot using a QueuedConnection. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop.

It's common to connect the QGuiApplication::lastWindowClosed() signal to quit()

I have a code very similar to yours and if it works onPause () and onResume (). When changing the fragment, these functions are activated respectively.

Code in fragment:

 @Override
public void onResume() {
    super.onResume();
    sensorManager.registerListener(this, proximidad, SensorManager.SENSOR_DELAY_NORMAL);
    sensorManager.registerListener(this, brillo, SensorManager.SENSOR_DELAY_NORMAL);
    Log.e("Frontales","resume");
}

@Override
public void onPause() {
    super.onPause();
    sensorManager.unregisterListener(this);
    Log.e("Frontales","Pause");

}

Log when change of fragment:

05-19 22:28:54.284 2371-2371/madi.cajaherramientas E/Frontales: resume
05-19 22:28:57.002 2371-2371/madi.cajaherramientas E/Frontales: Pause
05-19 22:28:58.697 2371-2371/madi.cajaherramientas E/Frontales: resume
05-19 22:29:00.840 2371-2371/madi.cajaherramientas E/Frontales: Pause
05-19 22:29:02.248 2371-2371/madi.cajaherramientas E/Frontales: resume
05-19 22:29:03.718 2371-2371/madi.cajaherramientas E/Frontales: Pause

Fragment onCreateView:

View rootView;
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    rootView = inflater.inflate(R.layout.activity_proximidad, container, false);
    ButterKnife.bind(this,rootView);
    inflar();
    setTextos();
    return rootView;
}

Action when I pulse back (in the activity where I load the fragment):

@Override
public void onBackPressed() {

    int count = getFragmentManager().getBackStackEntryCount();

    if (count == 0) {
        super.onBackPressed();

    } else {
        getFragmentManager().popBackStack();
    }

 }

If you are working with devtools try to save the files with:

devtools::use_data(x, internal = TRUE)

Then, delete all files saved previously.

From doc:

internal If FALSE, saves each object in individual .rda files in the data directory. These are available whenever the package is loaded. If TRUE, stores all objects in a single R/sysdata.rda file. These objects are only available within the package.

You have to move the css folder into your web folder. It seems that your web folder on the hard drive equals the /ServletApp folder as seen from the www. Other content than inside your web folder cannot be accessed from the browsers.

The url of the CSS link is then

 <link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>

Sticky navbar:

To make a sticky nav you need to add the class navbar-fixed-top to your nav

Official documentation:
http://getbootstrap.com/components/#navbar-fixed-top

Official example:
http://getbootstrap.com/examples/navbar-fixed-top/

A simple example code:

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container">
    ...
  </div>
</nav>

with related jsfiddle: http://jsfiddle.net/ur7t8/

Resize the navbar:

If you want the nav bar to resize while you scroll the page you can give a look to this example: http://www.bootply.com/109943

JS

$(window).scroll(function() {
  if ($(document).scrollTop() > 50) {
    $('nav').addClass('shrink');
  } else {
    $('nav').removeClass('shrink');
  }
});

CSS

nav.navbar.shrink {
  min-height: 35px;
}

Animation:

To add an animation while you scroll, all you need to do is set a transition on the nav

CSS

nav.navbar{
  background-color:#ccc;
   // Animation
   -webkit-transition: all 0.4s ease;
   transition: all 0.4s ease;
}

I made a jsfiddle with the full example code: http://jsfiddle.net/Filo/m7yww8oa/

You could use convert from the hablar package:

library(dplyr)
library(hablar)

# Sample df (stolen from the solution by Luca Braglia)
df <- tibble("a" = as.character(0:5),
                 "b" = paste(0:5, ".1", sep = ""),
                 "c" = letters[1:6])

# insert variable names in num()
df %>% convert(num(a, b))

Which gives you:

# A tibble: 6 x 3
      a     b c    
  <dbl> <dbl> <chr>
1    0. 0.100 a    
2    1. 1.10  b    
3    2. 2.10  c    
4    3. 3.10  d    
5    4. 4.10  e    
6    5. 5.10  f   

Or if you are lazy, let retype() from hablar guess the right data type:

df %>% retype()

which gives you:

# A tibble: 6 x 3
      a     b c    
  <int> <dbl> <chr>
1     0 0.100 a    
2     1 1.10  b    
3     2 2.10  c    
4     3 3.10  d    
5     4 4.10  e    
6     5 5.10  f   

if(!empty($_POST['filename'])){
$filename = $_POST['filename'];

echo $filename;
}

If you put an inverted comma at the start of the field, it will be interpreted as text.

Example: 25/12/2008 becomes '25/12/2008

You are also able to select the field type when importing.

Below is an alternative implementation of a 'create user' controller method using Claims based roles.

The created claims then work with the Authorize attribute e.g. [Authorize(Roles = "Admin, User.*, User.Create")]

    // POST api/User/Create
    [Route("Create")]
    public async Task<IHttpActionResult> Create([FromBody]CreateUserModel model)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        // Generate long password for the user
        var password = System.Web.Security.Membership.GeneratePassword(25, 5);

        // Create the user
        var user = new ApiUser() { UserName = model.UserName };
        var result = await UserManager.CreateAsync(user, password);
        if (!result.Succeeded)
        {
            return GetErrorResult(result);
        }

        // Add roles (permissions) for the user
        foreach (var perm in model.Permissions)
        {
            await UserManager.AddClaimAsync(user.Id, new Claim(ClaimTypes.Role, perm));
        }

        return Ok<object>(new { UserName = user.UserName, Password = password });
    }

I have 3 fields to fetch from Oracle Database,Which is for Forex and Currency Application.

The answer depends on what is in your hash. If you have a simple hash a simple

print map { "$_ $h{$_}\n" } keys %h;

or

print "$_ $h{$_}\n" for keys %h;

will do, but if you have a hash that is populated with references you will something that can walk those references and produce a sensible output. This walking of the references is normally called serialization. There are many modules that implement different styles, some of the more popular ones are:

• Data::Dumper
• Data::Dump::Streamer
• YAML::XS
• JSON::XS
• XML::Dumper

Due to the fact that Data::Dumper is part of the core Perl library, it is probably the most popular; however, some of the other modules have very good things to offer.

Try combo of split("/") and * for strings with existing joins.

import os

home = '/home/build/test/sandboxes/'
todaystr = '042118'
new = '/new_sandbox/'

os.path.join(*home.split("/"), todaystr, *new.split("/"))

How it works...

split("/") turns existing path into list: ['', 'home', 'build', 'test', 'sandboxes', '']

* in front of the list breaks out each item of list its own parameter

android.provider.telephony.SMS_RECEIVED is not correct because Telephony is a class and it should be capital as in android.provider.Telephony.SMS_RECEIVED

If you compute modulo a power of two, using bitwise AND is simpler and generally faster than performing division. If b is a power of two, a % b == a & (b - 1).

For example, let's take a value in register EAX, modulo 64.
The simplest way would be AND EAX, 63, because 63 is 111111 in binary.

The masked, higher digits are not of interest to us. Try it out!

Analogically, instead of using MUL or DIV with powers of two, bit-shifting is the way to go. Beware signed integers, though!

Instead of changing the ticks, why not change the units instead? Make a separate array X of x-values whose units are in nm. This way, when you plot the data it is already in the correct format! Just make sure you add a xlabel to indicate the units (which should always be done anyways).

from pylab import *

# Generate random test data in your range
N = 200
epsilon = 10**(-9.0)
X = epsilon*(50*random(N) + 1)
Y = random(N)

# X2 now has the "units" of nanometers by scaling X
X2 = (1/epsilon) * X

subplot(121)
scatter(X,Y)
xlim(epsilon,50*epsilon)
xlabel("meters")

subplot(122)
scatter(X2,Y)
xlim(1, 50)
xlabel("nanometers")

show()

A jQuery solution:

$("#frame1").ready( function() {

  $("#frame1").contents().scrollTop( $("#frame1").contents().scrollTop() + 10 );

});

Use jline3:

Example:

Terminal terminal = TerminalBuilder.builder()
    .jna(true)
    .system(true)
    .build();

// raw mode means we get keypresses rather than line buffered input
terminal.enterRawMode();
reader = terminal .reader();
...
int read = reader.read();
....
reader.close();
terminal.close();

I solved a similar problem by closing the project, then re-importing the project (not opening, but re-importing as an eclipse or other project)

An abstract class is a class that you can't create an object from, so it is mostly used for inheriting from.(I am not sure if you can have static methods in it)

An abstract method is a method that the child class must override, it does not have a body, is marked abstract and only abstract classes can have those methods.

The reason why you're getting that error is because you've declared your struct as:

struct {
 char name[32];
 int  size;
 int  start;
 int  popularity;
} stasher_file;

This is not declaring a stasher_file type. This is declaring an anonymous struct type and is creating a global instance named stasher_file.

What you intended was:

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

But note that while Brian R. Bondy's response wasn't correct about your error message, he's right that you're trying to write into the struct without having allocated space for it. If you want an array of pointers to struct stasher_file structures, you'll need to call malloc to allocate space for each one:

struct stasher_file *newFile = malloc(sizeof *newFile);
if (newFile == NULL) {
   /* Failure handling goes here. */
}
strncpy(newFile->name, name, 32);
newFile->size = size;
...

(BTW, be careful when using strncpy; it's not guaranteed to NUL-terminate.)

Just edit or add

On OSX, I used MacPorts to address the same problem when connecting to my siteground database. Siteground appears to be using 5.0.77mm0.1-log, but creating a new user account didn't fix the problem. This is what did

sudo port install php5-mysql -mysqlnd +mysql5

This downgrades the mysql driver that php will use.

Use position:fixed, as previously stated, IE6 doesn't recognize position:fixed, but with some css magic you can get IE6 to behave:

html, body {
    height: 100%;
    overflow:auto;
}
body #fixedElement {
    position:fixed !important;
    position: absolute; /*ie6 */
    bottom: 0;
}

The !important flag makes it so you don't have to use a conditional comment for IE. This will have #fixedElement use position:fixed in all browsers but IE, and in IE, position:absolute will take effect with bottom:0. This will simulate position:fixed for IE6

one cannot use the Context of the Service; was able to get the (package) Context alike:

Intent intent = new Intent(getApplicationContext(), SomeActivity.class);

Try getting the element with the ID and check if the return value is null:

document.getElementById('some_nonexistent_id') === null

If you're using jQuery, you can do:

$('#some_nonexistent_id').length === 0

Have a look at this sample:

public class A {
  //statements
}

public class B extends A {
  public void foo() { }
}

A a=new B();

//To execute **foo()** method.

((B)a).foo();

[Late answer in response to a bounty asking for newer responses]

Looking over earlier answers,

• Fetching and deleting all items, as suggested by @Grouchal and others, is still an effective and useful solution. If you have very large data stores then it might be slow, but it still works very well.
• Simply removing the data store is, as you and @groundhog note, no longer effective. It's obsolete even if you don't use external binary storage because iOS 7 uses WAL mode for SQLite journalling. With WAL mode there may be (potentially large) journal files sitting around for any Core Data persistent store.

But there's a different, similar approach to removing the persistent store that does work. The key is to put your persistent store file in its own sub-directory that doesn't contain anything else. Don't just stick it in the documents directory (or wherever), create a new sub-directory just for the persistent store. The contents of that directory will end up being the persistent store file, the journal files, and the external binary files. If you want to nuke the entire data store, delete that directory and they'll all disappear.

You'd do something like this when setting up your persistent store:

NSURL *storeDirectoryURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"persistent-store"];
if ([[NSFileManager defaultManager] createDirectoryAtURL:storeDirectoryURL
        withIntermediateDirectories:NO
        attributes:nil
        error:nil]) {
    NSURL *storeURL = [storeDirectoryURL URLByAppendingPathComponent:@"MyApp.sqlite"];
    // continue with storeURL as usual...
}

Then when you wanted to remove the store,

[[NSFileManager defaultManager] removeItemAtURL:storeDirectoryURL error:nil];

That recursively removes both the custom sub-directory and all of the Core Data files in it.

This only works if you don't already have your persistent store in the same folder as other, important data. Like the documents directory, which probably has other useful stuff in it. If that's your situation, you could get the same effect by looking for files that you do want to keep and removing everything else. Something like:

NSString *docsDirectoryPath = [[self applicationDocumentsDirectory] path];
NSArray *docsDirectoryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:docsDirectoryPath error:nil];
for (NSString *docsDirectoryItem in docsDirectoryContents) {
    // Look at docsDirectoryItem. If it's something you want to keep, do nothing.
    // If it's something you don't recognize, remove it.
}

This approach may be error prone. You've got to be absolutely sure that you know every file you want to keep, because otherwise you might remove important data. On the other hand, you can remove the external binary files without actually knowing the file/directory name used to store them.

You can just make sure your css file parses AFTER boostrap.css , like so:

<link href="css/bootstrap.css" rel="stylesheet">
<link href="css/myFile.css" rel="stylesheet">

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

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

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

See bobby-tables.com.

Just check for the null value and return false to it:

@{ bool nullableValue = ((Model.nullableValue == null) || (Model.nullableValue == false)) ? false : true; }
@Html.CheckBoxFor(model => nullableValue)

as suggested here solving the famous LazyInitializationException is one of the following methods:

(1) Use Hibernate.initialize

Hibernate.initialize(topics.getComments());

(2) Use JOIN FETCH

You can use the JOIN FETCH syntax in your JPQL to explicitly fetch the child collection out. This is somehow like EAGER fetching.

(3) Use OpenSessionInViewFilter

LazyInitializationException often occurs in the view layer. If you use Spring framework, you can use OpenSessionInViewFilter. However, I do not suggest you to do so. It may leads to a performance issue if not used correctly.

you can try this too And it will work:

DECLARE
  a NUMBER;
  b NUMBER;
BEGIN
  a :=: a; --this will take input from user
  b :=: b;
  DBMS_OUTPUT.PUT_LINE('a = '|| a);
  DBMS_OUTPUT.PUT_LINE('b = '|| b);
END;

That's probably the C++ runtime library. Since it's a DLL it is not included in your program executable. Your friend can download those libraries from Microsoft.

Sounds like your solution is quite plausible for this need, I honestly don't see a problem with it if your two key types are really distinct. Just makes ure you write your own implementation for this and deal with synchronization issues if needed.

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

Use datetime.timedelta()

>>> from datetime import date, timedelta
>>> yesterday = date.today() - timedelta(days=1)
>>> yesterday.strftime('%m%d%y')
'110909'

pst.setDate(6, new java.sql.Date(txtDate.getDate().getTime()));

this is the code I used to save date into the database using jdbc works fine for me

• pst is a variable for preparedstatement
• txtdate is the name for the JDateChooser

SELECT REPLACE(CONVERT(varchar(20), (CAST(9876543 AS money)), 1), '.00', '')

output= 9,876,543

and you can replace 9876543 by your column name.

For trivial applications (e.g. sporadically retrieving a temperature value from a web-enabled thermometer) HTTP 1.0 is fine for both a client and a server. You can write a bare-bones socket-based HTTP 1.0 client or server in about 20 lines of code.

For more complicated scenarios HTTP 1.1 is the way to go. Expect a 3 to 5-fold increase in code size for dealing with the intricacies of the more complex HTTP 1.1 protocol. The complexity mainly comes, because in HTTP 1.1 you will need to create, parse, and respond to various headers. You can shield your application from this complexity by having a client use an HTTP library, or server use a web application server.

Create a new file, and then on the filename use slash. For example

Java/Helloworld.txt

I know it's a quite old thread, but all these solutions are not completed and don't work on some devices when user rotates camera because data in onActivityResult is null. So here is solution which I have tested on lots of devices and haven't faced any problem so far.

First declare your Uri variable in your activity:

private Uri uriFilePath;

Then create your temporary folder for storing captured image and make intent for capturing image by camera:

PackageManager packageManager = getActivity().getPackageManager();
if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
    File mainDirectory = new File(Environment.getExternalStorageDirectory(), "MyFolder/tmp");
         if (!mainDirectory.exists())
             mainDirectory.mkdirs();

          Calendar calendar = Calendar.getInstance();

          uriFilePath = Uri.fromFile(new File(mainDirectory, "IMG_" + calendar.getTimeInMillis()));
          intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          intent.putExtra(MediaStore.EXTRA_OUTPUT, uriFilePath);
          startActivityForResult(intent, 1);
}

And now here comes one of the most important things, you have to save your uriFilePath in onSaveInstanceState, because if you didn't do that and user rotated his device while using camera, your uri would be null.

@Override
protected void onSaveInstanceState(Bundle outState) {
     if (uriFilePath != null)
         outState.putString("uri_file_path", uriFilePath.toString());
     super.onSaveInstanceState(outState);
}

After that you should always recover your uri in your onCreate method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
         if (uriFilePath == null && savedInstanceState.getString("uri_file_path") != null) {
             uriFilePath = Uri.parse(savedInstanceState.getString("uri_file_path"));
         }
    } 
}

And here comes last part to get your Uri in onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {    
    if (resultCode == RESULT_OK) {
         if (requestCode == 1) {
            String filePath = uriFilePath.getPath(); // Here is path of your captured image, so you can create bitmap from it, etc.
         }
    }
 }

P.S. Don't forget to add permissions for Camera and Ext. storage writing to your Manifest.

GSON is a good choice for Android and Web platform to parse JSON in a Kotlin project. This library is developed by Google. https://github.com/google/gson

1. First add GSON to your project:

dependencies {
   implementation 'com.google.code.gson:gson:2.8.6'
}

2. Now you need to convert your JSON to Kotlin Data class:

Copy your JSON and go to this(https://json2kt.com) website and paste your JSON to Input Json box. Write package(ex: com.example.appName) and Class name(ex: UserData) in proper box. This site will show live preview of your data class below and also you can download all classes at once in a zip file.

After downloading all classes extract zip file & place them into your project.

3. Now Parse like below:

val myJson = """
{
    "user_name": "john123",
    "email": "[email protected]",
    "name": "John Doe"
}
""".trimIndent()

val gson = Gson()
var mUser = gson.fromJson(myJson, UserData::class.java)
println(mUser.userName)

Done :)

Read up on List Comprehensions

[ (x,y) for x, y in a if x  == 1 ]

Also read up up generator functions and the yield statement.

def filter_value( someList, value ):
    for x, y in someList:
        if x == value :
            yield x,y

result= list( filter_value( a, 1 ) )

You can't directly edit your path to execute of a service. For that you can use sc command,

SC CONFIG ServiceName binPath= "Path of your file"

Eg:

sc config MongoDB binPath="I:\Programming\MongoDB\MongoDB\bin\mongod.exe --config I:\Programming\MongoDB\MongoDB\bin\mongod.cfg --service"

@Entity 
class Employee {
     @OneToOne(orphanRemoval=true)
     private Address address;
}

See here.

check if string(word/sentence...) contains specific word/character

if ( "write something here".indexOf("write som") > -1 )  { alert( "found it" );  } 

You can do it with a WITH clause.

For example:

WITH c AS (SELECT DISTINCT a, b, c FROM tableName)
SELECT * FROM tableName r, c WHERE c.rowid=r.rowid AND c.a=r.a AND c.b=r.b AND c.c=r.c

This also allows you to select only the rows selected in the WITH clauses query.

Here's a slide in/out animation between fragments:

FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.animator.enter_anim, R.animator.exit_anim);
transaction.replace(R.id.listFragment, new YourFragment());
transaction.commit();

We are using an objectAnimator.

Here are the two xml files in the animator subfolder.

enter_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set>
     <objectAnimator
         xmlns:android="http://schemas.android.com/apk/res/android"
         android:duration="1000"
         android:propertyName="x"
         android:valueFrom="2000"
         android:valueTo="0"
         android:valueType="floatType" />
</set>

exit_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set>
    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="1000"
        android:propertyName="x"
        android:valueFrom="0"
        android:valueTo="-2000"
        android:valueType="floatType" />
</set>

I hope that would help someone.

The NA can actually be due to 2 reasons. One is that there is a NA in your data. Another one is due to there being one of the values being constant. This results in standard deviation being equal to zero and hence the cor function returns NA.

The simplest way (java.specification.version):

double version = Double.parseDouble(System.getProperty("java.specification.version"));

if (version == 1.5) {
    // 1.5 specific code
} else {
    // ...
}

or something like (java.version):

String[] javaVersionElements = System.getProperty("java.version").split("\\.");

int major = Integer.parseInt(javaVersionElements[1]);

if (major == 5) {
    // 1.5 specific code
} else {
    // ...
}

or if you want to break it all up (java.runtime.version):

String discard, major, minor, update, build;

String[] javaVersionElements = System.getProperty("java.runtime.version").split("\\.|_|-b");

discard = javaVersionElements[0];
major   = javaVersionElements[1];
minor   = javaVersionElements[2];
update  = javaVersionElements[3];
build   = javaVersionElements[4];

I write a faster method for it can make the small one to set. But I test it in some data that some time it's faster that Intersect but some time Intersect fast that my code.

    public static bool Contain<T>(List<T> a, List<T> b)
    {
        if (a.Count <= 10 && b.Count <= 10)
        {
            return a.Any(b.Contains);
        }

        if (a.Count > b.Count)
        {
            return Contain((IEnumerable<T>) b, (IEnumerable<T>) a);
        }
        return Contain((IEnumerable<T>) a, (IEnumerable<T>) b);
    }

    public static bool Contain<T>(IEnumerable<T> a, IEnumerable<T> b)
    {
        HashSet<T> j = new HashSet<T>(a);
        return b.Any(j.Contains);
    }

The Intersect calls Set that have not check the second size and this is the Intersect's code.

        Set<TSource> set = new Set<TSource>(comparer);
        foreach (TSource element in second) set.Add(element);
        foreach (TSource element in first)
            if (set.Remove(element)) yield return element;

The difference in two methods is my method use HashSet and check the count and Intersect use set that is faster than HashSet. We dont warry its performance.

The test :

   static void Main(string[] args)
    {
        var a = Enumerable.Range(0, 100000);
        var b = Enumerable.Range(10000000, 1000);
        var t = new Stopwatch();
        t.Start();
        Repeat(()=> { Contain(a, b); });
        t.Stop();
        Console.WriteLine(t.ElapsedMilliseconds);//490ms

        var a1 = Enumerable.Range(0, 100000).ToList();
        var a2 = b.ToList();
        t.Restart();
        Repeat(()=> { Contain(a1, a2); });
        t.Stop();

        Console.WriteLine(t.ElapsedMilliseconds);//203ms

        t.Restart();
        Repeat(()=>{ a.Intersect(b).Any(); });
        t.Stop();
        Console.WriteLine(t.ElapsedMilliseconds);//190ms

        t.Restart();
        Repeat(()=>{ b.Intersect(a).Any(); });
        t.Stop();
        Console.WriteLine(t.ElapsedMilliseconds);//497ms

        t.Restart();
        a.Any(b.Contains);
        t.Stop();
        Console.WriteLine(t.ElapsedMilliseconds);//600ms

    }

    private static void Repeat(Action a)
    {
        for (int i = 0; i < 100; i++)
        {
            a();
        }
    }

The issue is that the original axiosTest() function isn't returning the promise. Here's an extended explanation for clarity:

function axiosTest() {
    // create a promise for the axios request
    const promise = axios.get(url)

    // using .then, create a new promise which extracts the data
    const dataPromise = promise.then((response) => response.data)

    // return it
    return dataPromise
}

// now we can use that data from the outside!
axiosTest()
    .then(data => {
        response.json({ message: 'Request received!', data })
    })
    .catch(err => console.log(err))

The function can be written more succinctly:

function axiosTest() {
    return axios.get(url).then(response => response.data)
}

Or with async/await:

async function axiosTest() {
    const response = await axios.get(url)
    return response.data
}

SMS Push uses SMS as a carrier, WAP uses download via WAP.

The table data on the hot standby slave server is modified while a long running query is running. A solution (PostgreSQL 9.1+) to make sure the table data is not modified is to suspend the replication and resume after the query:

select pg_xlog_replay_pause(); -- suspend
select * from foo; -- your query
select pg_xlog_replay_resume(); --resume

SELECT @LastChangeDate = GETDATE()

Git GUI has a PUSH button - pardon the pun, and the dialog box it opens has a checkbox for tags.

I pushed a branch from the command line, without tags, and then tried again pushing the branch using the --follow-tags option descibed above. The option is described as following annotated tags. My tags were simple tags.

I'd fixed something, tagged the commit with the fix in, (so colleagues can cherry pick the fix,) then changed the software version number and tagged the release I created (so colleagues can clone that release).

Git returned saying everything was up-to-date. It did not send the tags! Perhaps because the tags weren't annotated. Perhaps because there was nothing new on the branch.

When I did a similar push with Git GUI, the tags were sent.

For the time being, I am going to be pushing my changes to my remotes with Git GUI and not with the command line and --follow-tags.

if var == 'stringone' or var == 'stringtwo':
    dosomething()

'is' is used to check if the two references are referred to a same object. It compare the memory address. Apparently, 'stringone' and 'var' are different objects, they just contains the same string, but they are two different instances of the class 'str'. So they of course has two different memory addresses, and the 'is' will return False.

There are several scenarios to consider. First of all, you need to check the type of your object. You can simply call GetType() for this. If the type does not implement IDynamicMetaObjectProvider, then you can use reflection same as for any other object. Something like:

var propertyInfo = test.GetType().GetProperties();

However, for IDynamicMetaObjectProvider implementations, the simple reflection doesn't work. Basically, you need to know more about this object. If it is ExpandoObject (which is one of the IDynamicMetaObjectProvider implementations), you can use the answer provided by itowlson. ExpandoObject stores its properties in a dictionary and you can simply cast your dynamic object to a dictionary.

If it's DynamicObject (another IDynamicMetaObjectProvider implementation), then you need to use whatever methods this DynamicObject exposes. DynamicObject isn't required to actually "store" its list of properties anywhere. For example, it might do something like this (I'm reusing an example from my blog post):

public class SampleObject : DynamicObject
{
    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = binder.Name;
        return true;
    }
}

In this case, whenever you try to access a property (with any given name), the object simply returns the name of the property as a string.

dynamic obj = new SampleObject();
Console.WriteLine(obj.SampleProperty);
//Prints "SampleProperty".

So, you don't have anything to reflect over - this object doesn't have any properties, and at the same time all valid property names will work.

I'd say for IDynamicMetaObjectProvider implementations, you need to filter on known implementations where you can get a list of properties, such as ExpandoObject, and ignore (or throw an exception) for the rest.

use

You can insert using a Sub-query as follows:

INSERT INTO new_table (columns....)
SELECT columns....
FROM initial_table where column=value

you can try this one isNaN(Number(x)) where x is any thing like string or number

If you really want to do this with jQuery (why?) you should get the DOM window.location object to use its functions:

$(window.location)[0].replace("https://www.google.it");

Note that [0] says to jQuery to use directly the DOM object and not the $(window.location) jQuery object incapsulating the DOM object.

Either you use a framework or you write your own server with nodejs.

A simple fileserver may look like this:

import * as http from 'http';
import * as url from 'url';
import * as fs from 'fs';
import * as path from 'path';

var mimeTypes = {
     "html": "text/html",
     "jpeg": "image/jpeg",
     "jpg": "image/jpeg",
     "png": "image/png",
     "js": "text/javascript",
     "css": "text/css"};

http.createServer((request, response)=>{
    var pathname = url.parse(request.url).pathname;
    var filename : string;
    if(pathname === "/"){
        filename = "index.html";
    }
    else
        filename = path.join(process.cwd(), pathname);

    try{
        fs.accessSync(filename, fs.F_OK);
        var fileStream = fs.createReadStream(filename);
        var mimeType = mimeTypes[path.extname(filename).split(".")[1]];
        response.writeHead(200, {'Content-Type':mimeType});
        fileStream.pipe(response);
    }
    catch(e) {
            console.log('File not exists: ' + filename);
            response.writeHead(404, {'Content-Type': 'text/plain'});
            response.write('404 Not Found\n');
            response.end();
            return;
    }
    return;
    }
}).listen(5000);

As has been mentioned already, you cannot use the "Back up" and "Restore" features to go from a SQL Server 2012 DB to a SQL Server 2008 DB. A program I wrote, SQL Server Scripter, will however connect to a SQL Server database and script out a database, its schema and data. It can be git cloned from BitBucket, and compiled with Visual Studio 2010 or later (if it's a later version, just open the .csproj).

In my specific case I tried to create a React Native app using the react-native init installation process, when I encountered the discussed problem.

FAILURE: Build failed with an exception.

* What went wrong:

A problem occurred configuring project ':app'.
> SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at 'C:\Users\***\android\local.properties'.

I add this, because when developing an android app using react native, the 'root directory' to which so many answers refer, is actually the root of the android folder (and not the project's root folder, where App.js resides). This is also made clear by the directory marked in the error message.

To solve it, just add a local.properties file to the android folder, and type:

sdk.dir=C:/Users/{user name}/AppData/Local/Android/Sdk

Be sure to add the local disk's reference ('C:/'), because it did not work otherwise in my case.

A very short way to do it is just right click on the activity_main.xml design background and select convert view then select Relativealayout. Your code in Xml Text will auto. Change. Goodluck

Sometimes (not often!) you do truly know more about past, current and future memory usage then the run time does. This does not happen very often, and I would claim never in a web application while normal pages are being served.

Many year ago I work on a report generator, that

• Had a single thread
• Read the “report request” from a queue
• Loaded the data needed for the report from the database
• Generated the report and emailed it out.
• Repeated forever, sleeping when there were no outstanding requests.
• It did not reuse any data between reports and did not do any cashing.

Firstly as it was not real time and the users expected to wait for a report, a delay while the GC run was not an issue, but we needed to produce reports at a rate that was faster than they were requested.

Looking at the above outline of the process, it is clear that.

• We know there would be very few live objects just after a report had been emailed out, as the next request had not started being processed yet.
• It is well known that the cost of running a garbage collection cycle is depending on the number of live objects, the amount of garbage has little effect on the cost of a GC run.
• That when the queue is empty there is nothing better to do then run the GC.

Therefore clearly it was well worth while doing a GC run whenever the request queue was empty; there was no downside to this.

It may be worth doing a GC run after each report is emailed, as we know this is a good time for a GC run. However if the computer had enough ram, better results would be obtained by delaying the GC run.

This behaviour was configured on a per installation bases, for some customers enabling a forced GC after each report greatly speeded up the protection of reports. (I expect this was due to low memory on their server and it running lots of other processes, so hence a well time forced GC reduced paging.)

We never detected an installation that did not benefit was a forced GC run every time the work queue was empty.

But, let be clear, the above is not a common case.

Using the following 1 line command for changing many files name in linux using phrase specificity:

find -type f -name '*.jpg' | rename 's/holiday/honeymoon/'

For all files with the extension ".jpg", if they contain the string "holiday", replace it with "honeymoon". For instance, this command would rename the file "ourholiday001.jpg" to "ourhoneymoon001.jpg".

This example also illustrates how to use the find command to send a list of files (-type f) with the extension .jpg (-name '*.jpg') to rename via a pipe (|). rename then reads its file list from standard input.

I was hoping to find a solution to this as well. I see that this is an older post, but hoping my approach might simplify this problem for someone else.

I was using a combobox with a drop down style of DropDownList, but this should work with other styles. In my case I wanted the text to read "Select Source" and I wanted the other options to be "File" and "Folder"

comboBox1.Items.AddRange(new string[] {"Select Source", "File", "Folder" });
comboBox1.Text = "Select Source";

You can select the 0 index instead if you like. I then removed the "Select Source" item when the index is changed as it no longer matters if that text is visible.

comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_IndexChanged);

private void comboBox1_IndexChanged(object sender, EventArgs e)
    {
        comboBox1.Items.Remove("Select Source");
        if (comboBox1.SelectedIndex != -1)
        {
            if (comboBox1.SelectedIndex == 0) // File
            {
                // Do things
            }
            else if (comboBox1.SelectedIndex == 1) // Folder
            {
                // Do things
            }
        }
    }

Dir.glob(File.join('path', '**', '*.rb'), &method(:require))

or alternatively, if you want to scope the files to load to specific folders:

Dir.glob(File.join('path', '{folder1,folder2}', '**', '*.rb'), &method(:require))

explanation:

Dir.glob takes a block as argument.

method(:require) will return the require method.

&method(:require) will convert the method to a bloc.

FileReaderJS can read the files for you. You get the file content inside onLoad(e) event handler as e.target.result.

If you are using VS Code, you can rename the .ts, .html, .css/.scss, .spec.ts files and the IDE will take care of the imports for you. Therefore there will be no complaints from the files that import files from your component (such as app.module.ts). However, you will still have to rename the component name everywhere it is being used.

Just do

openssl x509 -req -days 365 -in server.cer -signkey server.key -out server.crt

Make the outer div position="relative" and the inner div position="absolute" and set it's bottom="0".

If you want a condition to show elements, you can use something like this.

renderButton() {
    if (this.state.loading) {
        return <Spinner size="small" spinnerStyle={styles.spinnerStyle} />;
    }

    return (
        <Button onPress={this.onButtonPress.bind(this)}>
            Log In
        </Button>
    );
}

Then call the helping method inside render function.

<View style={styles.buttonStyle}>
      {this.renderButton()}
</View>

Or you can use another way of condition inside return.

{this.props.hasImage ? <element1> : <element2>}

I would do it in the application, actually. It's still configurable at runtime, depending on your logger system, of course. For example, if you use Apache Log (log4j/cxx) you could configure a dedicated logger for such URLs and then configure it at runtime from an XML file.

In getUserById you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user. Otherwise Hibernate.initialize(user); is actually Hibernate.initialize(null);

Here's the new getUserById (I haven't tested this ;)):

public User getUserById(Long user_id) {
    Session session = null;
    Object user = null;
    try {
        session = HibernateUtil.getSessionFactory().openSession();
        user = (User)session.load(User.class, user_id);
        Hibernate.initialize(user);
    } catch (Exception e) {
       e.printStackTrace();
    } finally {
        if (session != null && session.isOpen()) {
            session.close();
        }
    }
    return user;
}

The Character class of Java API has various functions you can use.

You can convert your char to lowercase at both sides:

Character.toLowerCase(name1.charAt(i)) == Character.toLowerCase(name2.charAt(j))

There are also a methods you can use to verify if the letter is uppercase or lowercase:

Character.isUpperCase('P')
Character.isLowerCase('P') 

The answers are already kind of outdated or not complete. This maybe works for non-protected apks (no Proguard), but nowadays nobody deploys an unprotected apk. The way I was able to modify a (my) well-protected apk (Proguard, security check which checks for "hacking tools", security check, which checks if the app is repackaged with debug mode,...) is via apktool as already mentioned by other ones here. But nobody explained, that you have to sign the app again.

apktool d app.apk
//generates a folder with smali bytecode files. 

//Do something with it.

apktool b [folder name] -o modified.apk
//generates the modified apk.

//and then
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore modified.apk androiddebugkey
//signs the app the the debug key (the password is android)

//this apk can be installed on a device.

In my test, the original release apk had no logging. After I decompiled with apktool I exchanged a full byte code file without logging by a full byte code file with logging, re-compiled and signed it and I was able to install it on my device. Afterwards I was able to see the logs in Android Studio as I connected the app to it.

In my opinion, decompiling with dex2jar and JD-GUI is only helpful to get a better understanding what the classes are doing, just for reading purposes. But since everything is proguarded, I'm not sure that you can ever re-compile this half-baked Java code to a working apk. If so, please let me know. I think, the only way is to manipulate the byte code itself as mentioned in this example.

You can use fmt.Sprintf or strconv.FormatFloat

For example

package main

import (
    "fmt"
)

func main() {
    val := 14.7
    s := fmt.Sprintf("%f", val)
    fmt.Println(s)
}

Random generator = new Random(); 
int i = generator.nextInt(10) + 1;

Add the @CreationTimestamp annotation:

@CreationTimestamp
@Column(name="timestamp", nullable = false, updatable = false, insertable = false)
private Timestamp timestamp;

If you don't mind using jQuery you can use the code bellow:

    <script>
     $(document).ready(function(){
           $("#department").val("${requestScope.selectedDepartment}").attr('selected', 'selected');
     });
     </script>


    <select id="department" name="department">
      <c:forEach var="item" items="${dept}">
        <option value="${item.key}">${item.value}</option>
      </c:forEach>
    </select>

In the your Servlet add the following:

        request.setAttribute("selectedDepartment", YOUR_SELECTED_DEPARTMENT );

In mi and vivo - Using the above solution is not enough. You must also tell the user to add permission manually. You can help them by opening the right location inside phone settings. Varies for different phone models.

The Request Payload - or to be more precise: payload body of a HTTP Request - is the data normally send by a POST or PUT Request. It's the part after the headers and the CRLF of a HTTP Request.

A request with Content-Type: application/json may look like this:

POST /some-path HTTP/1.1
Content-Type: application/json

{ "foo" : "bar", "name" : "John" }

If you submit this per AJAX the browser simply shows you what it is submitting as payload body. That’s all it can do because it has no idea where the data is coming from.

If you submit a HTML-Form with method="POST" and Content-Type: application/x-www-form-urlencoded or Content-Type: multipart/form-data your request may look like this:

POST /some-path HTTP/1.1
Content-Type: application/x-www-form-urlencoded

foo=bar&name=John

In this case the form-data is the request payload. Here the Browser knows more: it knows that bar is the value of the input-field foo of the submitted form. And that’s what it is showing to you.

So, they differ in the Content-Type but not in the way data is submitted. In both cases the data is in the message-body. And Chrome distinguishes how the data is presented to you in the Developer Tools.

print('\007')

Plays the bell sound on Linux. Plays the error sound on Windows 10.

Just because nobody mentioned it yet: using RAW(1) also seems common practice.

The hexadecimal value you are looking for is %2B

To get it automatically in PHP run your string through urlencode($stringVal). And then run it rhough urldecode($stringVal) to get it back.

If you want the JavaScript to handle it, use escape( str )

Edit

After @bobince's comment I did more reading and he is correct. Use encodeURIComponent(str) and decodeURIComponent(str). Escape will not convert the characters, only escape them with \'s

pip3 install BeautifulSoup4

Try this. It works for me. The reason is well explained here..

The problem can be solved by configuring pylint path under venv: $ cat .vscode/settings.json

{
    "python.pythonPath": "venv/bin/python",
    "python.linting.pylintPath": "venv/bin/pylint"
}

char **options[2][100];

declares a size-2 array of size-100 arrays of pointers to pointers to char. You'll want to remove one *. You'll also want to put your string literals in double quotes.

Hi this issue is because docker containers exit if there is no running application in the container.

-d 

option is just to run a container in deamon mode.

So the trick to make your container continuously running is point to a shell file in docker which will keep your application running.You can try with a start.sh file

Eg: docker run -d centos sh /yourlocation/start.sh

This start.sh should point to a never ending application.

In case if you dont want any application to be running,you can install monit which will keep your docker container running. Please let us know if these two cases worked for you to keep your container running.

All the best

you need length() function

select length(customer_name) from ar.ra_customers

Note that in an attribute selector (e.g., [attr~=value]), the tilde

Represents an element with an attribute name of attr whose value is a whitespace-separated list of words, one of which is exactly value.

https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors

This will do the trick :-

new Date().valueOf() 

You're not actually going out after the values. You would need to gather them like this:

var title   = document.getElementById("title").value;
var name    = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;

You could put all of these in one array:

var myArray = [ title, name, tickets ];

Or many arrays:

var titleArr   = [ title ];
var nameArr    = [ name ];
var ticketsArr = [ tickets ];

Or, if the arrays already exist, you can use their .push() method to push new values onto it:

var titleArr = [];

function addTitle ( title ) {
  titleArr.push( title );
  console.log( "Titles: " + titleArr.join(", ") );
}

Your save button doesn't work because you refer to this.form, however you don't have a form on the page. In order for this to work you would need to have <form> tags wrapping your fields:

I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit

The new form follows:

<form>
  <h1>Please enter data</h1>
  <input id="title" type="text" />
  <input id="name" type="text" />
  <input id="tickets" type="text" />
  <input type="button" value="Save" onclick="insert()" />
  <input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>

There is still some room for improvement, such as removing the onclick attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).

I've also made some changes to your JavaScript. I start by creating three empty arrays:

var titles  = [];
var names   = [];
var tickets = [];

Now that we have these, we'll need references to our input fields.

var titleInput  = document.getElementById("title");
var nameInput   = document.getElementById("name");
var ticketInput = document.getElementById("tickets");

I'm also getting a reference to our message display box.

var messageBox  = document.getElementById("display");

The insert() function uses the references to each input field to get their value. It then uses the push() method on the respective arrays to put the current value into the array.

Once it's done, it cals the clearAndShow() function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.

function insert ( ) {
 titles.push( titleInput.value );
 names.push( nameInput.value );
 tickets.push( ticketInput.value );

 clearAndShow();
}

This function, as previously stated, starts by setting the .value property of each input to an empty string. It then clears out the .innerHTML of our message box. Lastly, it calls the join() method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.

function clearAndShow () {
  titleInput.value = "";
  nameInput.value = "";
  ticketInput.value = "";

  messageBox.innerHTML = "";

  messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
  messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
  messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}

Found this post and I realize it's a bit old, but I think I might have an answer. This handles the click on the cross, backspacing and hitting the ESC key. I am sure it could probably be written better - I'm still relatively new to javascript. Here is what I ended up doing - I am using jQuery (v1.6.4):

var searchVal = ""; //create a global var to capture the value in the search box, for comparison later
$(document).ready(function() {
  $("input[type=search]").keyup(function(e) {
    if (e.which == 27) {  // catch ESC key and clear input
      $(this).val('');
    }
    if (($(this).val() === "" && searchVal != "") || e.which == 27) {
      // do something
      searchVal = "";
    }
    searchVal = $(this).val();
  });
  $("input[type=search]").click(function() {
    if ($(this).val() != filterVal) {
      // do something
      searchVal = "";
    }
  });
});

why dont you do something like:

re = /^[a-z0-9 ]$/i;
var isValid = re.test(yourInput);

to check if your input contain any special char

See this link to a Case Study on Caching:

Summary, according to the article, only Cache-Control: no-store works on Chrome, Firefox and IE. IE accepts other controls, but Chrome and Firefox do not. The link is a good read complete with the history of caching and documenting proof of concept.

Modern jQuery

Use .prop():

$('.myCheckbox').prop('checked', true);
$('.myCheckbox').prop('checked', false);

DOM API

If you're working with just one element, you can always just access the underlying HTMLInputElement and modify its .checked property:

$('.myCheckbox')[0].checked = true;
$('.myCheckbox')[0].checked = false;

The benefit to using the .prop() and .attr() methods instead of this is that they will operate on all matched elements.

jQuery 1.5.x and below

The .prop() method is not available, so you need to use .attr().

$('.myCheckbox').attr('checked', true);
$('.myCheckbox').attr('checked', false);

Note that this is the approach used by jQuery's unit tests prior to version 1.6 and is preferable to using $('.myCheckbox').removeAttr('checked'); since the latter will, if the box was initially checked, change the behaviour of a call to .reset() on any form that contains it – a subtle but probably unwelcome behaviour change.

For more context, some incomplete discussion of the changes to the handling of the checked attribute/property in the transition from 1.5.x to 1.6 can be found in the version 1.6 release notes and the Attributes vs. Properties section of the .prop() documentation.

Completing the solution of Ranadheer, using Server.MapPath to locate the file

mail.Attachments.Add(attachment);

It should be noted that if you use push --force with mutiple refs, they will ALL be modified as a result. Make sure to pay attention to where your git repo is configured to push to. Fortunately there is a way to safeguard the process slightly, by specifying a single branch to update. Read from the git man pages:

Note that --force applies to all the refs that are pushed, hence using it with push.default set to matching or with multiple push destinations configured with remote.*.push may overwrite refs other than the current branch (including local refs that are strictly behind their remote counterpart). To force a push to only one branch, use a + in front of the refspec to push (e.g git push origin +master to force a push to the master branch).

here's the incantation for nginx, inside a

location / {
    # Simple requests
    if ($request_method ~* "(GET|POST)") {
      add_header "Access-Control-Allow-Origin"  *;
    }

    # Preflighted requests
    if ($request_method = OPTIONS ) {
      add_header "Access-Control-Allow-Origin"  *;
      add_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, HEAD";
      add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept";
    }

}

The code works well for me.

$str = substr($str ,-(strlen($str)-1));

Maybe, contribute with answers too.
