Programs & Examples On #Dead letter

First, create your Module. You can do that using the default Android Studio Module Wizard (File -> New -> New Module), select Android Library, give it a Name and a package name, and finish. After that you will see that nothing happens. Open the side Gradle Projects Section (should be somewhere on the right panel)

You should see something like this:

Expand your module gradle and run the Run Configurations task. After that refresh the content and refresh the project structure.

It should work now.

I encountered

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from projects)

The cause was that I had not started the MySQL server.

It may help to check that the MySQL is running as the first step in troubleshooting the error.

Max has the best solution for when you always want to start both projects, but you can also right click a project and choose menu Debug ? Start New Instance.

This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).

Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.

Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.

If you are comparing schemas on the same database then try:

select * from dba_objects 
   where schema_name = 'ASCHEMA' 
     and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects 
where schema_name = 'BSCHEMA' 
  and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )

and switch around the orders of ASCHEMA and BSCHEMA.

If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas

Use this method and pass your array in parameter

Collections.shuffle(arrayList);

This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.

You can now use arraylist which is shuffled.

You can't... an array's size is always fixed in Java. Typically instead of using an array, you'd use an implementation of List<T> here - usually ArrayList<T>, but with plenty of other alternatives available.

You can create an array from the list as a final step, of course - or just change the signature of the method to return a List<T> to start with.

In case you're using apache's http-client 4:

SSLConnectionSocketFactory sslConnectionSocketFactory = 
    new SSLConnectionSocketFactory(sslContext,
             new String[] { "TLSv1.2" }, null, new HostnameVerifier() {
                    public boolean verify(String arg0, SSLSession arg1) {
                            return true;
            }
      });

Note that the wmode=transparent fix only works if it's first so

Not

Have a look at insertAdjacentHTML

var element = document.getElementById("one");
var newElement = '<div id="two">two</div>'
element.insertAdjacentHTML( 'afterend', newElement )
// new DOM structure: <div id="one">one</div><div id="two">two</div>

position is the position relative to the element you are inserting adjacent to:

'beforebegin' Before the element itself

'afterbegin' Just inside the element, before its first child

'beforeend' Just inside the element, after its last child

'afterend' After the element itself

If you are converting to HTML, you can set the size of the image using HTML syntax using:

  <img src="path/to/image" height="400px" width="300px" />

or whatever height and width you would want to give.

 //this will work for user in time zone MST with 7 off set or UTC with saving time 

 //I have tried all the above and they fail the only solution is to use some math
 //the trick is to rely on $newdate is time()     //strtotime is corrupt it tries to read to many minds

 $dnol = strtotime('today')*1000;
 $dn = ($newdate*1000)-86400000;
 $dz=$dn/86400000;      //divide into days
 $dz=floor($dz);     //filter off excess time

Steps to follow Remove Modules in Android Studio:3.1.4.

1. Goto Project-->Right Click on Module (FolderIcon-GreywithGreenColorDot) -->Load/UnLoadModules in PopUp -->Select Which Module to Unload in PopUpWindow

2. Again RightClick on Module (FolderIcon-OrangeColor) -->Remove module.

3. Finally, RightClick again on Module (FolderIcon-GreyColor) -->Delete.

   Note:Incase Project Enabled with Git please remove module from settings.gradle, otherwise deleted module.iml will show in project module list(Reference Link).gradle.xml which is located in project/.idea/gradle.xml--remove a module from here.

Hope it helps. Thank-you.

If it helps to anyone, I currently use VMWare Workstation in my computer, and it also blocks Apache from starting, because VMWare Workstation listens for requests on port 443.

You can either comment out "listen 443" inside the "httpd-ssl.config" or you can disable "Shared VMs" from VMWare Workstation General Preferences.

I was having the same issue and this works excellently.

Private Sub DataGridView17_CellFormatting(sender As Object, e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView17.CellFormatting

It seems your curl points to a non-existing file with CA certs or similar.

For the primary reference on CA certs with curl, see: https://curl.haxx.se/docs/sslcerts.html

This may sound like an unhelpful answer ... But why are you using a LinkButton for something purely client-side? Use a standard HTML anchor tag and set its onclick action to your Javascript.

If you need the server to generate the text of that link, then use an asp:Label as the content between the anchor's start and end tags.

If you need to dynamically change the script behavior based on server-side code, consider asp:Literal as a technique.

But unless you're doing server-side activity from the Click event of the LinkButton, there just doesn't seem to be much point to using it here.

You might check Select2 plugin:

http://ivaynberg.github.io/select2/

Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.

It's quite popular and very maintainable. It should cover most of your needs if not all.

 <label for="fileEdit">
    <i class="fa fa-cloud-upload">
    </i>
    <input id="fileEdit" class="hidden" type="file" name="addImg" ng-file-change="onImageChange( $files )" ng-multiple="false" accept="{{ contentType }}"/>
  </label>

For example you can use this : label with hidden input (icon is present).

The answer of Logan Capaldo is correct but can be marginally simplified because it is unnecessary to specialize the class every time. One can write:

// in header
template<typename T>
struct TypeParseTraits
{ static const char* name; };

// in c-file
#define REGISTER_PARSE_TYPE(X) \
    template <> const char* TypeParseTraits<X>::name = #X

REGISTER_PARSE_TYPE(int);
REGISTER_PARSE_TYPE(double);
REGISTER_PARSE_TYPE(FooClass);
// etc...

This also allows you to put the REGISTER_PARSE_TYPE instructions in a C++ file...

Also, you can use shelljs plugin. It's easy and it's cross-platform.

Install command:

npm install [-g] shelljs

What is shellJS

ShellJS is a portable (Windows/Linux/OS X) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects - say goodbye to those gnarly Bash scripts!

An example of how it works:

var shell = require('shelljs');

if (!shell.which('git')) {
  shell.echo('Sorry, this script requires git');
  shell.exit(1);
}

// Copy files to release dir
shell.rm('-rf', 'out/Release');
shell.cp('-R', 'stuff/', 'out/Release');

// Replace macros in each .js file
shell.cd('lib');
shell.ls('*.js').forEach(function (file) {
  shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);
  shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);
  shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);
});
shell.cd('..');

// Run external tool synchronously
if (shell.exec('git commit -am "Auto-commit"').code !== 0) {
  shell.echo('Error: Git commit failed');
  shell.exit(1);
}

Also, you can use from the command line:

$ shx mkdir -p foo
$ shx touch foo/bar.txt
$ shx rm -rf foo

You can use em for percentage instead of pixels,

Example:

border:10PX dotted #c1a9ff; /* In Pixels */
border:0.75em dotted #c1a9ff; /* Exact same as above in Percentage */

From what I gather, Matz does not like the construct

begin
    <multiple_lines_of_code>
end while <cond>

because, it's semantics is different than

<single_line_of_code> while <cond>

in that the first construct executes the code first before checking the condition, and the second construct tests the condition first before it executes the code (if ever). I take it Matz prefers to keep the second construct because it matches one line construct of if statements.

I never liked the second construct even for if statements. In all other cases, the computer executes code left-to-right (eg. || and &&) top-to-bottom. Humans read code left-to-right top-to-bottom.

I suggest the following constructs instead:

if <cond> then <one_line_code>      # matches case-when-then statement

while <cond> then <one_line_code>

<one_line_code> while <cond>

begin <multiple_line_code> end while <cond> # or something similar but left-to-right

I don't know if those suggestions will parse with the rest of the language. But in any case I prefere keeping left-to-right execution as well as language consistency.

@IhorSakaylyuk's answer can be improved further down to O(sqrt(n/2)) by skipping all of the even numbers except 2:

const isPrime = number => {
    if(num % 2 === 0 && number !== 2) return false
    for(let i = 3, s = Math.sqrt(num); i <= s; i += 2)
        if(num % i === 0) return false; 
    return num > 1;
}

You can also use the npm package pial.

Use the flex-grow property to make a flex item consume free space on the main axis.

This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.

A common example is flex-grow: 1 or, using the shorthand property, flex: 1.

Hence, instead of width: 96% on your div, use flex: 1.

You wrote:

So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.

The squashing of the fixed-width div is related to another flex property: flex-shrink

By default, flex items are set to flex-shrink: 1 which enables them to shrink in order to prevent overflow of the container.

To disable this feature use flex-shrink: 0.

For more details see The flex-shrink factor section in the answer here:

• What are the differences between flex-basis and width?

Learn more about flex alignment along the main axis here:

• In CSS Flexbox, why are there no "justify-items" and "justify-self" properties?

Remove -Werror from your Make or CMake files, as suggested in this post

It sounds like your printMousePos function should:

1. Get the X and Y coordinates of the mouse
2. Add those values to the HTML

Currently, it does this:

1. Creates (undefined) variables for the X and Y coordinates of the mouse
2. Attaches a function to the "mousemove" event (which will set those variables to the mouse coordinates when triggered by a mouse move)
3. Adds the current values of your variables to the HTML

See the problem? Your variables are never getting set, because as soon as you add your function to the "mousemove" event you print them.

It seems like you probably don't need that mousemove event at all; I would try something like this:

function printMousePos(e) {
    var cursorX = e.pageX;
    var cursorY = e.pageY;
    document.getElementById('test').innerHTML = "x: " + cursorX + ", y: " + cursorY;
}

You can try with

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

I had this problem, after installing jdk7 next to Java 6. The binaries were correctly updated using update-alternatives --config java to jdk7, but the $JAVA_HOME environment variable still pointed to the old directory of Java 6.

Use toString() when you want to present information to a user (including a developer looking at a log). Never rely in your code on toString() giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString() return, then it was already broken.

If you need to get the exact name used to declare the enum constant, you should use name() as toString may have been overridden.

According to Javascript Date Documentation, you can easily do this way:

var twoHoursBefore = new Date();
twoHoursBefore.setHours(twoHoursBefore.getHours() - 2);

And don't worry about if hours you set will be out of 0..23 range. Date() object will update the date accordingly.

For Android API level 13 and you need to use this:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int maxX = size.x; 
int maxY = size.y;

Then (0,0) is top left corner and (maxX,maxY) is bottom right corner of the screen.

The 'getWidth()' for screen size is deprecated since API 13

Furthermore getwidth() and getHeight() are methods of android.view.View class in android.So when your java class extends View class there is no windowManager overheads.

          int maxX=getwidht();
          int maxY=getHeight();

as simple as that.

My favorite rendering of the procedures list of the current database: name, parameters list, comment

SELECT specific_name AS name, param_list AS params, `comment`
FROM mysql.proc
WHERE db = DATABASE()
AND type = 'PROCEDURE';

Add returns for functions:

SELECT specific_name AS name, param_list AS params, `returns`, `comment`
FROM mysql.proc
WHERE db = DATABASE()
AND type = 'FUNCTION';

I had a similar issue. I added write permissions to the .bak file itself, and my folder that I was writing the backup to for the NETWORK SERVICE user. To add permissions just right-click what file/directory you want to alter, select the security tab, and add the appropriate users/permissions there.

Since .NET 2.0 you can use:

// Indicates whether the specified string is null or an Empty string.
string.IsNullOrEmpty(string value);

Additionally, since .NET 4.0 there's a new method that goes a bit farther:

// Indicates whether a specified string is null, empty, or consists only of white-space characters.
string.IsNullOrWhiteSpace(string value);

If you have a dataset named daily_data:

daily_data<-daily_data[order(as.Date(daily_data$date, format="%d/%m/%Y")),] 

The latest PowerShell version as of Sept 2015 is PowerShell 4.0. It's bundled with Windows Management Framework 4.0.

Here's the download page for PowerShelll 4.0 for all versions of Windows. For Windows 7, there are 2 links on that page, 1 for x64 and 1 for x86.

Strange behaviour which I was experienced also. So for me "return false" did the trick.

        $( '#selector' ).on( 'click', function() {
            //code
            return false;
        });

There are a lot of implementations that can be used. The most obvious seems to be something like this:

String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, "");
};

" foo bar ".trim();  // "foo bar"

Easiest and power full way

read only radio inputs using getAttribute

document.addEventListener('input',(e)=>{

if(e.target.getAttribute('name')=="myRadios")
console.log(e.target.value)
})

<input type="radio" name="myRadios" value="1" /> 1
<input type="radio" name="myRadios" value="2" /> 2

Try something like this:

public boolean checkNull() throws IllegalAccessException {
    for (Field f : getClass().getDeclaredFields())
        if (f.get(this) != null)
            return false;
    return true;            
}

Although it would probably be better to check each variable if at all feasible.

1. Download the file from http://www.java2s.com/Code/Jar/STUVWXYZ/Downloadjavaxservletjar.htm

2. Make a folder ("lib") inside the project folder and move that jar file to there.

3. In Eclipse, right click on project > BuildPath > Configure BuildPath > Libraries > Add External Jar

Thats all

I created a docker container for doing exactly that https://github.com/qoomon/docker-host

You can then simply use container name dns to access host system e.g. curl http://dockerhost:9200

Bootstrap has it's own classes for borders including .rounded-0 to get rid of rounded corners on any element including buttons

https://getbootstrap.com/docs/4.4/utilities/borders/#border-radius

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<a class="btn btn-primary">Regular Rounded Corners</a>_x000D_
<a class="btn btn-primary rounded-pill">Pill Corners</a>_x000D_
<a class="btn btn-primary rounded-0">Square Corners</a>

If you want to concatenate a variable with a fixed path and a string as the dynamic path into a whole path to remove the folder, you may need the following command:

$fixPath = "C:\Users\myUserName\Desktop"
Remove-Item ("$fixPath" + "\Folder\SubFolder") -Recurse

In the variable $newPath the concatenate path is now: "C:\Users\myUserName\Desktop\Folder\SubFolder"

So you can remove several directories from the starting point ("C:\Users\myUserName\Desktop"), which is already defined and fixed in the variable $fixPath.

$fixPath = "C:\Users\myUserName\Desktop"
Remote-Item ("$fixPath" + "\Folder\SubFolder") -Recurse
Remote-Item ("$fixPath" + "\Folder\SubFolder1") -Recurse
Remote-Item ("$fixPath" + "\Folder\SubFolder2") -Recurse

Leading on from Andrew's answer with regards to c#2 and c#3 ... you can also do them inline for a one off search function (see below).

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> list = new List<int> { 1, 2, 3 };

        List<int> newList = list.FindAll(delegate(int arg)
                           {
                               return arg> 2;
                           });
    }
}

Hope this helps.

For C++ users, to increase the Build console output size see here

I always find it easier to learn a language in a specific problem domain. You might try looking at Django and doing the tutorial. This will give you a very light-weight intro to both Python and to a web framework (a very well-documented one) that is 100% Python.

Then do something in your field(s) of expertise -- graph generation, or whatever -- and tie that into a working framework to see if you got it right. My universe tends to be computational linguistics and there are a number of Python-based toolkits to help get you started. E.g. Natural Language Toolkit.

Just a thought.

If you want your anchor to still appear to be clickable:

$("a").removeAttr("href").css("cursor","pointer");

And if you wanted to remove the href from only anchors with certain attributes (eg ones that just have a hash mark as the href - this can be useful in asp.net)

$("a[href='#']").removeAttr("href").css("cursor","pointer");

I though I'd add one more way. In my case I supply this to com.hazelcast.config.XmlConfigBuilder which only needs java.util.Properties to resolve some properties inside the Hazelcast XML configuration file, i.e. it only calls getProperty(String) method. So, this allowed me to do what I needed:

@RequiredArgsConstructor
public class SpringReadOnlyProperties extends Properties {

  private final org.springframework.core.env.Environment delegate;

  @Override
  public String getProperty(String key) {
    return delegate.getProperty(key);
  }

  @Override
  public String getProperty(String key, String defaultValue) {
    return delegate.getProperty(key, defaultValue);
  }

  @Override
  public synchronized String toString() {
    return getClass().getName() + "{" + delegate + "}";
  }

  @Override
  public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass()) return false;
    if (!super.equals(o)) return false;
    SpringReadOnlyProperties that = (SpringReadOnlyProperties) o;
    return delegate.equals(that.delegate);
  }

  @Override
  public int hashCode() {
    return Objects.hash(super.hashCode(), delegate);
  }

  private void throwException() {
    throw new RuntimeException("This method is not supported");
  }

  //all methods below throw the exception

  * override all methods *
}

P.S. I ended up not using this specifically for Hazelcast because it only resolves properties for XML file but not at runtime. Since I also use Spring, I decided to go with a custom org.springframework.cache.interceptor.AbstractCacheResolver#getCacheNames. This resolves properties for both situations, at least if you use properties in cache names.

Following Code authenticates from LDAP using pure Java JNDI. The Principle is:-

1. First Lookup the user using a admin or DN user.
2. The user object needs to be passed to LDAP again with the user credential
3. No Exception means - Authenticated Successfully. Else Authentication Failed.

Code Snippet

public static boolean authenticateJndi(String username, String password) throws Exception{
    Properties props = new Properties();
    props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    props.put(Context.PROVIDER_URL, "ldap://LDAPSERVER:PORT");
    props.put(Context.SECURITY_PRINCIPAL, "uid=adminuser,ou=special users,o=xx.com");//adminuser - User with special priviledge, dn user
    props.put(Context.SECURITY_CREDENTIALS, "adminpassword");//dn user password


    InitialDirContext context = new InitialDirContext(props);

    SearchControls ctrls = new SearchControls();
    ctrls.setReturningAttributes(new String[] { "givenName", "sn","memberOf" });
    ctrls.setSearchScope(SearchControls.SUBTREE_SCOPE);

    NamingEnumeration<javax.naming.directory.SearchResult> answers = context.search("o=xx.com", "(uid=" + username + ")", ctrls);
    javax.naming.directory.SearchResult result = answers.nextElement();

    String user = result.getNameInNamespace();

    try {
        props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        props.put(Context.PROVIDER_URL, "ldap://LDAPSERVER:PORT");
        props.put(Context.SECURITY_PRINCIPAL, user);
        props.put(Context.SECURITY_CREDENTIALS, password);

   context = new InitialDirContext(props);
    } catch (Exception e) {
        return false;
    }
    return true;
}

Create Button and add image as its background swift 4

     let img = UIImage(named: "imgname")
     let myButton = UIButton(type: UIButtonType.custom)
     myButton.frame = CGRect.init(x: 10, y: 10, width: 100, height: 45)
     myButton.setImage(img, for: .normal)
     myButton.addTarget(self, action: #selector(self.buttonClicked(_:)), for: UIControlEvents.touchUpInside)
     self.view.addSubview(myButton)

All these tips will work, but a simpler way might be to include your stylesheet after the Bootstrap styles.

If you include your css (site-specific.css) after Bootstrap's (bootstrap.css), you can override rules by redefining them.

For example, if this is how you include CSS in your <head>

<link rel="stylesheet" href="css/bootstrap.css" />
<link rel="stylesheet" href="css/site-specific.css" />

You can simply move the sidebar to the right by writing (in your site-specific.css file):

.sidebar {
    float: right;
}

Forgive the lack of HAML and SASS, I do not know them well enough to write tutorials in them.

I had the same issue, so I first SSH into the server to confirm that I able to log in to the server by using the command:

ssh -i /Users/Desktop/mypemfile.pem [email protected]

Then in New Terminal

I copied a small file to the server by using SCP, to make sure I am able to make a connection:

scp -i /Users/Desktop/mypemfile.pem /Users/Desktop/test.file [email protected]:/home/user/test/

Then In the same new terminal, I tried running rsync:

rsync -avz -e "ssh -i /Users/Desktop/mypemfile.pem" /Users/Desktop/backup/image.img.gz [email protected]:

This is another clean solution:

sub, sup {vertical-align: baseline; position: relative; font-size: 70%;} /* 70% size of its parent element font-size which is good. */
sub {bottom: -0.6em;} /* use em becasue they adapt to parent font-size */
sup {top: -0.6em;} /* use em becasue they adapt to parent font-size */

In this way you can still use sup/sub tags but you fixed their idious behavior to always screw up paragraph line height.

So now you can do:

  <p>This is a line of text.</p>
  <p>This is a line of text, <sub>with sub text.</sub></p>
  <p>This is a line of text, <sup>with sup text.</sup></p>
  <p>This is a line of text.</p>

And your paragraph line height should not get screwed up.

Tested on IE7, IE8, FF3.6, SAFARI4, CHROME5, OPERA9

I tested using a p {line-height: 1.3;} (that is a good line height unless you want your lines to stick too close) and it still works, cause "-0.6em" is such a small amount that also with that line height the sub/sub text will fit and don't go over each other.

Forgot a detail that might be relevant I always use DOCTYPE in the 1st line of my page (specifically I use the HTML 4.01 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">). So I don't know if this solution works well when browser is in quirkmode (or not standard mode) due to lack of DOCTYPE or to a DOCTYPE that does not triggers Standard/Almost Standard mode.

According to this link: signature help

APK Signature Scheme v2 offers:

1. Faster app install times
2. More protection against unauthorized alterations to APK files.

Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files. By default, Android Studio 2.2 and the Android Plugin for Gradle 2.2 sign your app using both APK Signature Scheme v2 and the traditional signing scheme, which uses JAR signing.

It is recommended to use APK Signature Scheme v2 but is not mandatory.

Although we recommend applying APK Signature Scheme v2 to your app, this new scheme is not mandatory. If your app doesn't build properly when using APK Signature Scheme v2, you can disable the new scheme.

A new library called ts-optchain provides this functionality, and unlike lodash' solution, it also keeps your types safe, here is a sample of how it is used (taken from the readme):

import { oc } from 'ts-optchain';

interface I {
  a?: string;
  b?: {
    d?: string;
  };
  c?: Array<{
    u?: {
      v?: number;
    };
  }>;
  e?: {
    f?: string;
    g?: () => string;
  };
}

const x: I = {
  a: 'hello',
  b: {
    d: 'world',
  },
  c: [{ u: { v: -100 } }, { u: { v: 200 } }, {}, { u: { v: -300 } }],
};

// Here are a few examples of deep object traversal using (a) optional chaining vs
// (b) logic expressions. Each of the following pairs are equivalent in
// result. Note how the benefits of optional chaining accrue with
// the depth and complexity of the traversal.

oc(x).a(); // 'hello'
x.a;

oc(x).b.d(); // 'world'
x.b && x.b.d;

oc(x).c[0].u.v(); // -100
x.c && x.c[0] && x.c[0].u && x.c[0].u.v;

oc(x).c[100].u.v(); // undefined
x.c && x.c[100] && x.c[100].u && x.c[100].u.v;

oc(x).c[100].u.v(1234); // 1234
(x.c && x.c[100] && x.c[100].u && x.c[100].u.v) || 1234;

oc(x).e.f(); // undefined
x.e && x.e.f;

oc(x).e.f('optional default value'); // 'optional default value'
(x.e && x.e.f) || 'optional default value';

// NOTE: working with function value types can be risky. Additional run-time
// checks to verify that object types are functions before invocation are advised!
oc(x).e.g(() => 'Yo Yo')(); // 'Yo Yo'
((x.e && x.e.g) || (() => 'Yo Yo'))();

For the instance:

if (obj is IMyInterface) {}

For the class:

Check if typeof(MyClass).GetInterfaces() contains the interface.

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

you could use display: inline-block;

hope it is useful.

Excel 2010 driver is 64 bit, while the default SSMS import export wizard is 32 therefore the error message.

You can import using the Import Export Data (64 bit) tool. ("C:\Program Files\Microsoft SQL Server\110\DTS\Binn\DTSWizard.exe") notice the path is not Program Files x86.

testVar = raw_input("Ask user for something.")

A bit more readable comparing is done by casting event.key to upper case (I used onkeyup - needed the event to fire once upon each key tap):

window.onkeyup = function(event) {
    let key = event.key.toUpperCase();
    if ( key == 'W' ) {
        // 'W' key is pressed
    } else if ( key == 'D' ) {
        // 'D' key is pressed
    }
}

Each key has it's own code, get it out by outputting value of "key" variable (eg for arrow up key it will be 'ARROWUP' - (casted to uppercase))

In any web application, there will be a web.xml in the WEB-INF/ folder.

If you dont have one in your web app, as it seems to be the case in your folder structure, the default Tomcat web.xml is under TOMCAT_HOME/conf/web.xml

Either way, the relevant lines of the web.xml are

<welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

so any file matching this pattern when found will be shown as the home page.

In Tomcat, a web.xml setting within your web app will override the default, if present.

You can use the .forEach() method of JavaScript for looping through JSON.

var datesBooking = [_x000D_
    {"date": "04\/24\/2018"},_x000D_
      {"date": "04\/25\/2018"}_x000D_
    ];_x000D_
    _x000D_
    datesBooking.forEach(function(data, index) {_x000D_
      console.log(data);_x000D_
    });

The first time I realized that the Unit testing project referenced the app.config in that project rather then the app.config associated with my production code project (off course, DOH) I just added a line in the Post Build Event of the Prod project that will copy the app.config to the bin folder of the test project.

Problem solved

I haven't noticed any weird side effects so far, but I am not sure that this is the right solution, but at least it seems to work.

For those that have Windows XP and have MySQL server 5.5 installed - the location for the database is C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\data, unless you changed the location within the MySql Workbench installation GUI.

Use the rawurlencode function instead.

You have to create a password file: see http://www.postgresql.org/docs/9.0/interactive/libpq-pgpass.html for more info.

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

I would like to share an answer that also demonstrates approach using the Android SDK provided by the Ubuntu repository:

Install Android SDK

sudo apt-get install android-sdk

Export environmental variables

export ANDROID_HOME="/usr/lib/android-sdk/"
export PATH="${PATH}:${ANDROID_HOME}tools/:${ANDROID_HOME}platform-tools/"

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

yes, there is:

object[] x = new object[2];

x[0] = new { firstName = "john", lastName = "walter" };
x[1] = new { brand = "BMW" };

you were practically there, just the declaration of the anonymous types was a little off.

If the error message is just

"Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.", then grant the login permission for 'NT AUTHORITY\NETWORK SERVICE'

by using

"sp_grantlogin 'NT AUTHORITY\NETWORK SERVICE'" 

else if the error message is like

"Cannot open database "Phaeton.mdf" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'."

try using

"EXEC sp_grantdbaccess 'NT AUTHORITY\NETWORK SERVICE'" 

under your "Phaeton" database.

    string stringToDecrypt = CypherText.Replace(" ", "+");
    int len = stringToDecrypt.Length;
    byte[] inputByteArray = Convert.FromBase64String(stringToDecrypt); 

You can use the Console API (which made its appearance in Java 6) as follows:

Console cons = System.console();
if(cons != null) {
  char c = (char) cons.reader().read();  // Checking for EOF omitted
  ...
}

If you just need a single line you don't even need to go through the reader object:

String s = cons.readLine();

In vanilla/pure javascript you can check as following -

var field = document.querySelector("input[name='fieldName']");
if(field.readOnly){
 alert("foo");
}

I also used the bash4 way but I find and annoying bug.

I needed to update dynamically the associative array content so i used this way:

for instanceId in $instanceList
do
   aws cloudwatch describe-alarms --output json --alarm-name-prefix $instanceId| jq '.["MetricAlarms"][].StateValue'| xargs | grep -E 'ALARM|INSUFFICIENT_DATA'
   [ $? -eq 0 ] && statusCheck+=([$instanceId]="checkKO") || statusCheck+=([$instanceId]="allCheckOk"
done

I find out that with bash 4.3.11 appending to an existing key in the dict resulted in appending the value if already present. So for example after some repetion the content of the value was "checkKOcheckKOallCheckOK" and this was not good.

No problem with bash 4.3.39 where appenging an existent key means to substisture the actuale value if already present.

I solved this just cleaning/declaring the statusCheck associative array before the cicle:

unset statusCheck; declare -A statusCheck

Some people have already mentioned HttpURLConnection, URL and URLConnection. If you need all the control and extra features that the curl library provides you (and more), I'd recommend Apache's httpclient.

Just create an extension for the StringBuilder class:

Public Module Extensions
    <Extension()>
    Public Sub AppendFormatWithNewLine(ByRef sb As System.Text.StringBuilder, ByVal format As String, ParamArray values() As Object)
        sb.AppendLine(String.Format(format, values))
    End Sub
End Module

Windows doesn't ignore anything. This is an issue with your setup; Windows just uses what you provide. It has no special knowledge of JAVA_HOME.

CLASSPATH has nothing to do with Windows, either. To Windows it's only an environmental variable that gets expanded to a folder location.

Check your %PATH% environmental variable. It's what's making Windows find one before the other. The path (as the post you linked to said) should point to %JAVA_HOME%\bin;<remainder of path>. Again, the post you linked to gave you a way to set this using a batch file.

(For others who might not know this: The easiest way to inspect the %PATH% is to open a command prompt and type echo %PATH%. You can also get there by right-clicking on Computer in the right pane of the Start Menu and choosing Properties, then Advanced System Settings, and the tne Environmental Variables button.)

Use regular expression:

int i=Integer.parseInt("hello123".replaceAll("[\\D]",""));
int j=Integer.parseInt("123hello".replaceAll("[\\D]",""));
int k=Integer.parseInt("1h2el3lo".replaceAll("[\\D]",""));

output:

i=123;
j=123;
k=123;

There are a few. I was looking into MBTrading for a friend. I didn't get too far, as my friend lost interest. Seemed relatively straigt forward with a C# and VB.Net SDK. They had some docs and everything. This was ~6 months ago, so it may be better (or worse) by now.

IIRC, you can create a demo account for free. I don't remember all the details, but it let you connect to their test server and pull quotes and make fake trades and such to get your software fine tuned.

Don't know much about cost for an actual account or anything.

Assuming a list like below - and assuming some of the options were selected ... (this is a multi select, but this will also work on a single select.

<select multiple='multiple' id='selectListName'> 
    <option>1</option> 
    <option>2</option> 
    <option>3</option> 
    <option>4</option>
</select>

In some function called based on some event, the following code would clear all selected options.

$("#selectListName").prop('selectedIndex', -1);

Okay... Finally I could install it! Why? or what I did? well I am not sure. first I downloaded and installed the package (I installed all the files(3) from the disk image) but I couldn't start it. (nor from the preferences panel, nor from the termial)

second I removed it and installed through mac ports.

again, the same thing. could not start it.

Now I deleted it again, installed from the package. (i am not sure if it was the exact same package but I think it is) Only this time I got the package from another site(its a mirror).

the site:

http://www.mmisoftware.co.uk/weblog/2009/08/29/mac-os-x-10-6-snow-leopard-and-mysql/

and the link:

http://mirror.services.wisc.edu/mysql/Downloads/MySQL-5.1/mysql-5.1.37-osx10.5-x86.dmg

1.- install mysql-5-1.37-osx10.5-x86.pkg

2.- install MySQLStartupItem.pkg

3.- install MySQL.prefpanel

And this time is working fine (even the preferences panel!)

Nothing special, I don't know what happened the first two times.

But thank you all. Regards.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

try it:

const cors = require('cors')

const corsOptions = {

}
app.use(cors(corsOptions));

Quote the Windows help for the set command (set /?):

If Command Extensions are enabled, then there are several dynamic
environment variables that can be expanded but which don't show up in
the list of variables displayed by SET.  These variable values are
computed dynamically each time the value of the variable is expanded.
If the user explicitly defines a variable with one of these names, then
that definition will override the dynamic one described below:

%CD% - expands to the current directory string.

%DATE% - expands to current date using same format as DATE command.

%TIME% - expands to current time using same format as TIME command.

%RANDOM% - expands to a random decimal number between 0 and 32767.

%ERRORLEVEL% - expands to the current ERRORLEVEL value

%CMDEXTVERSION% - expands to the current Command Processor Extensions
    version number.

%CMDCMDLINE% - expands to the original command line that invoked the
    Command Processor.

Note the %CD% - expands to the current directory string. part.

var array=[];

array.push(array);  //insert the array value using push methods.

for (var i = 0; i < array.length; i++) {    
    nameList += "" + array[i] + "";          //display the array value.                                                             
}

$("id/class").html(array.length);   //find the array length.

you can use this:

 \str_getcsv($str,PHP_EOL);

If it worked the way you expected it to (resulting in "abc9"), what would "9" + 9 deliver? 18 or "99"?

To remove this ambiguity, you are required to make explicit what you want to convert in this case:

"abc" + str(9)

String s = "String="

String[] str = s.split("="); //now str[0] is "hello" and str[1] is "goodmorning,2,1"

add this string

you can also use

word-break: break-all;

when nothing seems working this works always ;)

to keep it simple: EOF is an integer type with value -1. Therefore, we must use an integer variable to test EOF.

I was able to implement the Child form inside the parent.

In the Example below Form2 should change to the name of your child form. NewMDIChild.MdiParent=me is the main form since the control that opens (shows) the child form is the parent or Me.

NewMDIChild.Show() is your child form since you associated your child form with Dim NewMDIChild As New Form2()

Protected Sub MDIChildNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem2.Click
   Dim NewMDIChild As New Form2()
   'Set the Parent Form of the Child window.
   NewMDIChild.MdiParent = Me
   'Display the new form.
   NewMDIChild.Show()
End Sub

Simple and it works.

From your service method:

function serviceMethod() {
    return $timeout(function() {
        return {
            property: 'value'
        };
    }, 1000);
}

And in your controller:

serviceName
    .serviceMethod()
    .then(function(data){
        //handle the success condition here
        var x = data.property
    });

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

Why not just set the left two columns to a fixed with in your own css and then make a new grid layout of the full 12 columns for the rest of the content?

<div class="row">
    <div class="fixed-1">Left 1</div>
    <div class="fixed-2">Left 2</div>
    <div class="row">
        <div class="col-md-1"></div>
        <div class="col-md-11"></div>
    </div>
</div>

cacerts is where Java stores public certificates of root CAs. Java uses cacerts to authenticate the servers.

Keystore is where Java stores the private keys of the clients so that it can share it to the server when the server requests client authentication.

 Date.prototype.AddDays = function (days) {
    days = parseInt(days, 10);
    return new Date(this.valueOf() + 1000 * 60 * 60 * 24 * days);
}

Example

var dt = new Date();
console.log(dt.AddDays(-30));
console.log(dt.AddDays(-10));
console.log(dt.AddDays(-1));
console.log(dt.AddDays(0));
console.log(dt.AddDays(1));
console.log(dt.AddDays(10));
console.log(dt.AddDays(30));

Had a similar problem where we wanted to update from deprecated Http module to HttpClient in Angular 7. But the application is large and need to change res.json() in a lot of places. So I did this to have the new module with back support.

return this.http.get(this.BASE_URL + url)
      .toPromise()
      .then(data=>{
        let res = {'results': JSON.stringify(data),
        'json': ()=>{return data;}
      };
       return res; 
      })
      .catch(error => {
        return Promise.reject(error);
      });

Adding a dummy "json" named function from the central place so that all other services can still execute successfully before updating them to accommodate a new way of response handling i.e. without "json" function.

Try this:

var frm = document.getElementById('search-theme-form') || null;
if(frm) {
   frm.action = 'whatever_you_need.ext' 
}

Late to the party here, but I often use this construct for doing ad-hoc padding of some value n, known to be a positive, decimal:

(offset + n + '').substr(1);

Where offset is 10^^digits.

E.g. Padding to 5 digits, where n = 123:

(1e5 + 123 + '').substr(1); // => 00123

The hexidecimal version of this is slightly more verbose:

(0x100000 + 0x123).toString(16).substr(1); // => 00123

Note 1: I like @profitehlolz's solution as well, which is the string version of this, using slice()'s nifty negative-index feature.

Semaphore can be counted, while mutex can only count to 1.

Suppose you have a thread running which accepts client connections. This thread can handle 10 clients simultaneously. Then each new client sets the semaphore until it reaches 10. When the Semaphore has 10 flags, then your thread won't accept new connections

Mutex are usually used for guarding stuff. Suppose your 10 clients can access multiple parts of the system. Then you can protect a part of the system with a mutex so when 1 client is connected to that sub-system, no one else should have access. You can use a Semaphore for this purpose too. A mutex is a "Mutual Exclusion Semaphore".

Based on your requirements you can also do the following without libraries like jQuery:

Add this to your head:

window.onload = function () {
    document.getElementById("frmSubmit").onsubmit = function onSubmit(form) {
        var isValid = true;
        //validate your elems here
        isValid = false;

        if (!isValid) {
            alert("Please check your fields!");
            return false;
        }
        else {
            //you are good to go
            return true;
        }
    }
}

And your form may still look something like:

    <form id="frmSubmit" action="/Submit">
        <input type="submit" value="Submit" />
    </form>

You can use LIKE statement instead of =. But to do this with DateStamp you need to CONVERT it first to VARCHAR:

SELECT * 
FROM [User] U
WHERE CONVERT(VARCHAR, U.DateCreated, 120) LIKE '2014-02-07%'

You're using an Array like an "associative array", which does not exist in JavaScript. Use an Object ({}) instead.

If you are going to continue with an array, realize that toString() will join all the numbered properties together separated by a comma. (the same as .join(",")).

Properties like a and b will not come up using this method because they are not in the numeric indexes. (ie. the "body" of the array)

In JavaScript, Array inherits from Object, so you can add and delete properties on it like any other object. So for an array, the numbered properties (they're technically just strings under the hood) are what counts in methods like .toString(), .join(), etc. Your other properties are still there and very much accessible. :)

Read Mozilla's documentation for more information about Arrays.

var aa = [];

// these are now properties of the object, but not part of the "array body"
aa.a = "A";
aa.b = "B";

// these are part of the array's body/contents
aa[0] = "foo";
aa[1] = "bar";

aa.toString(); // most browsers will say "foo,bar" -- the same as .join(",")

Also, note that XDocument is supported in Xbox 360 and Windows Phone OS 7.0. If you target them, develop for XDocument or migrate from XmlDocument.

If I recall correctly, gcc determines the filetype from the suffix. So, make it foo.cc and it should work.

And, to answer your other question, that is the difference between "gcc" and "g++". gcc is a frontend that chooses the correct compiler.

Don't forget to use var/let while declaring any variable.See below examples for JS compiler behaviour.

function  func(){
return true;
}

isBool = func();
console.log(typeof (isBool));   // output - string


let isBool = func();
console.log(typeof (isBool));   // output - boolean

Actually what made this so confusing is that the Beanstalk people stand behind their very non-standard use of Staging (it comes before development in their diagram, and it's not a mistake!

Adding kernel means you want to use Jupyter Notebook with versions of python which are not showing up in the list.

Simple approach- Start notebook with required python version, suppose I have python3.7 installed then use below command from terminal (cmd) to run notebook:

python3.7 -m notebook

Sometimes instead of python3.7 it's install with alias of py, py3.7, python.

There's public static class AbstractMap.SimpleEntry<K,V>. Don't let the Abstract part of the name mislead you: it is in fact NOT an abstract class (but its top-level AbstractMap is).

The fact that it's a static nested class means that you DON'T need an enclosing AbstractMap instance to instantiate it, so something like this compiles fine:

Map.Entry<String,Integer> entry =
    new AbstractMap.SimpleEntry<String, Integer>("exmpleString", 42);

As noted in another answer, Guava also has a convenient static factory method Maps.immutableEntry that you can use.

You said:

I can't use Map.Entry itself because apparently it's a read-only object that I can't instantiate new instanceof

That's not entirely accurate. The reason why you can't instantiate it directly (i.e. with new) is because it's an interface Map.Entry.

Caveat and tip

As noted in the documentation, AbstractMap.SimpleEntry is @since 1.6, so if you're stuck to 5.0, then it's not available to you.

To look for another known class that implements Map.Entry, you can in fact go directly to the javadoc. From the Java 6 version

Interface Map.Entry

All Known Implementing Classes:

• AbstractMap.SimpleEntry, AbstractMap.SimpleImmutableEntry

Unfortunately the 1.5 version does not list any known implementing class that you can use, so you may have be stuck with implementing your own.

Try this change border-color to anything which you want

.form-control:focus {
  border-color: #666666;

The Task.Run got introduced in newer .NET framework version and it is recommended.

Starting with the .NET Framework 4.5, the Task.Run method is the recommended way to launch a compute-bound task. Use the StartNew method only when you require fine-grained control for a long-running, compute-bound task.

The Task.Factory.StartNew has more options, the Task.Run is a shorthand:

The Run method provides a set of overloads that make it easy to start a task by using default values. It is a lightweight alternative to the StartNew overloads.

And by shorthand I mean a technical shortcut:

public static Task Run(Action action)
{
    return Task.InternalStartNew(null, action, null, default(CancellationToken), TaskScheduler.Default,
        TaskCreationOptions.DenyChildAttach, InternalTaskOptions.None, ref stackMark);
}

I think Microsoft guide for ASP.NET Identity is a good start.

https://docs.microsoft.com/en-us/aspnet/identity/overview/features-api/account-confirmation-and-password-recovery-with-aspnet-identity

Note:

If you do not use AccountController and wan't to reset your password, use Request.GetOwinContext().GetUserManager<ApplicationUserManager>();. If you dont have the same OwinContext you need to create a new DataProtectorTokenProvider like the one OwinContext uses. By default look at App_Start -> IdentityConfig.cs. Should look something like new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));.

Could be created like this:

Without Owin:

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset()
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));

    var email = "[email protected]";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset(string token)
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));
    var email = "[email protected]";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

With Owin:

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin()
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "[email protected]";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin(string token)
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "[email protected]";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

The DpapiDataProtectionProvider and DataProtectorTokenProvider needs to be created with the same name for a password reset to work. Using Owin for creating the password reset token and then creating a new DpapiDataProtectionProvider with another name won't work.

Code that I use for ASP.NET Identity:

Web.Config:

<add key="AllowedHosts" value="example.com,example2.com" />

AccountController.cs:

[Route("RequestResetPasswordToken/{email}/")]
[HttpGet]
[AllowAnonymous]
public async Task<IHttpActionResult> GetResetPasswordToken([FromUri]string email)

    if (!ModelState.IsValid)
        return BadRequest(ModelState);

        return NoContent();

I had the same problem.I solved with following command maven:

mvn eclipse:eclipse -Dwtpversion=2.0

PS: My project is WTP plugin

try using the permission of WRITE_EXTERNAL_STORAGE You should use that whether there is an external card or not.

This works well for me:

path = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_MOVIES);
File file = new File(path, "/" + fname);

and places my files in the appropriate folder

JAXB is an ideal solution. But you do not necessarily need xsd and xjc for that. More often than not you don't have an xsd but you know what your xml is. Simply analyze your xml, e.g.,

<customer id="100">
    <age>29</age>
    <name>mkyong</name>
</customer>

Create necessary model class(es):

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

    @XmlElement
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    @XmlElement
    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

Try to unmarshal:

JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(new File("C:\\file.xml"));

Check results, fix bugs!

DateTime dt1 = DateTime.Now.Date;
DateTime dt2 = Convert.ToDateTime(TextBox4.Text.Trim()).Date;

    MessageBox.Show("Invalid Date... Please Give Correct Date....");
}

Others are correct in saying that setting button.enabled = false doesn't prevent the button from triggering. However, I found that setting button.visible = false does work. The button disappears and can't be clicked until you set visible to true again.

Now only I came across this situation and found some more interesting features around GROUP_CONCAT. I hope these details will make you feel interesting.

simple GROUP_CONCAT

SELECT GROUP_CONCAT(TaskName) 
FROM Tasks;

Result:

+------------------------------------------------------------------+
| GROUP_CONCAT(TaskName)                                           |
+------------------------------------------------------------------+
| Do garden,Feed cats,Paint roof,Take dog for walk,Relax,Feed cats |
+------------------------------------------------------------------+

GROUP_CONCAT with DISTINCT

SELECT GROUP_CONCAT(TaskName) 
FROM Tasks;

Result:

+------------------------------------------------------------------+
| GROUP_CONCAT(TaskName)                                           |
+------------------------------------------------------------------+
| Do garden,Feed cats,Paint roof,Take dog for walk,Relax,Feed cats |
+------------------------------------------------------------------+

GROUP_CONCAT with DISTINCT and ORDER BY

SELECT GROUP_CONCAT(DISTINCT TaskName ORDER BY TaskName DESC) 
FROM Tasks;

Result:

+--------------------------------------------------------+
| GROUP_CONCAT(DISTINCT TaskName ORDER BY TaskName DESC) |
+--------------------------------------------------------+
| Take dog for walk,Relax,Paint roof,Feed cats,Do garden |
+--------------------------------------------------------+

GROUP_CONCAT with DISTINCT and SEPARATOR

SELECT GROUP_CONCAT(DISTINCT TaskName SEPARATOR ' + ') 
FROM Tasks;

Result:

+----------------------------------------------------------------+
| GROUP_CONCAT(DISTINCT TaskName SEPARATOR ' + ')                |
+----------------------------------------------------------------+
| Do garden + Feed cats + Paint roof + Relax + Take dog for walk |
+----------------------------------------------------------------+

GROUP_CONCAT and Combining Columns

SELECT GROUP_CONCAT(TaskId, ') ', TaskName SEPARATOR ' ') 
FROM Tasks;

Result:

+------------------------------------------------------------------------------------+
| GROUP_CONCAT(TaskId, ') ', TaskName SEPARATOR ' ')                                 |
+------------------------------------------------------------------------------------+
| 1) Do garden 2) Feed cats 3) Paint roof 4) Take dog for walk 5) Relax 6) Feed cats |
+------------------------------------------------------------------------------------+

GROUP_CONCAT and Grouped Results Assume that the following are the results before using GROUP_CONCAT

Use the keys method: {"apple" => "fruit", "carrot" => "vegetable"}.keys == ["apple", "carrot"]

1. It is a class in org.openqa.selenium.remote.DesiredCapabilities package.
2. It gives facility to set the properties of browser. Such as to set BrowserName, Platform, Version of Browser.
3. Mostly DesiredCapabilities class used when do we used Selenium Grid.
4. We have to execute mutiple TestCases on multiple Systems with different browser with Different version and Different Operating System.

Example:

WebDriver driver;
String baseUrl , nodeUrl;
baseUrl = "https://www.facebook.com";
nodeUrl = "http://192.168.10.21:5568/wd/hub";

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setBrowserName("firefox");
capability.setPlatform(Platform.WIN8_1);

driver = new RemoteWebDriver(new URL(nodeUrl),capability);
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES);

I agree with the use of instanceof already mentioned.

An additional benefit of using instanceof is that when used with a null reference instanceof of will return false, while a.getClass() would throw a NullPointerException.

Above solutions not helped me, but I resolve same issue by next way

private setHeaders(params) {      
        const accessToken = this.localStorageService.get('token');
        const reqData = {
            headers: {
                Authorization: `Bearer ${accessToken}`
            },
        };
        if(params) {
            let reqParams = {};        
            Object.keys(params).map(k =>{
                reqParams[k] = params[k];
            });
            reqData['params'] = reqParams;
        }
        return reqData;
    }

and send request

this.http.get(this.getUrl(url), this.setHeaders(params))

Its work with NestJS backend, with other I don't know.

There is no google play store in avd emulator. But you can install it manually.

1. Install Google APIs System Image, so you will have google services already (without play store)

2. Create AVD based on Google APIs image

3. Download smallest archive from http://opengapps.org/ and extract Phonesky.apk from it

4. Push Phonesky.apk to /system/priv-app/ on avd.

5. Restart avd. Google play should be there.

Recently I've just tried to do it by myself and you can find detailed tutorial on my blog: http://linuxoidchannel.blogspot.com/2017/01/how-to-install-google-play-store-on.html

Hope to helpful!

NewScores is an alias to Scores table - it looks like you can combine the queries as follows:

SELECT 
    ROW_NUMBER() OVER( ORDER BY NETT) AS Rank, 
    Name, 
    FlagImg, 
    Nett, 
    Rounds 
FROM (
    SELECT 
        Members.FirstName + ' ' + Members.LastName AS Name, 
        CASE 
            WHEN MenuCountry.ImgURL IS NULL THEN 
                '~/images/flags/ismygolf.png' 
            ELSE 
                MenuCountry.ImgURL 
        END AS FlagImg, 
        AVG(CAST(NewScores.NetScore AS DECIMAL(18, 4))) AS Nett, 
        COUNT(Score.ScoreID) AS Rounds 
    FROM 
        Members 
        INNER JOIN 
        Score NewScores
            ON Members.MemberID = NewScores.MemberID 
        LEFT OUTER JOIN MenuCountry 
            ON Members.Country = MenuCountry.ID 
    WHERE 
        Members.Status = 1 
        AND NewScores.InsertedDate >= DATEADD(mm, -3, GETDATE())
    GROUP BY

This is a great answer: https://stackoverflow.com/a/986977/5914609

However in my case it did not work. And i spent hours searching for the solution.
Finally i've returned to above code and added !important to each style. And it worked.
I can not add comments below the original answer. So here is the fix:

function getScrollBarWidth () {
  var inner = document.createElement('p');
  inner.style.width = "100% !important";
  inner.style.height = "200px !important";

  var outer = document.createElement('div');
  outer.style.position = "absolute !important";
  outer.style.top = "0px !important";
  outer.style.left = "0px !important";
  outer.style.visibility = "hidden !important";
  outer.style.width = "200px !important";
  outer.style.height = "150px !important";
  outer.style.overflow = "hidden !important";
  outer.appendChild (inner);

  document.body.appendChild (outer);
  var w1 = inner.offsetWidth;
  outer.style.overflow = 'scroll !important';
  var w2 = inner.offsetWidth;
  if (w1 == w2) w2 = outer.clientWidth;

  document.body.removeChild (outer);

  return (w1 - w2);
};

Maybe the sample is oversimplified, but you don't need the Java stream API here. Just use the Map directly.

 List<String> list1 = id1.get(1); // this will return the list from your map

The first thing I'd look at is a database. However, serialization is an option. If you go for binary serialization, then I would avoid BinaryFormatter - it has a tendency to get angry between versions if you change fields etc. Xml via XmlSerialzier would be fine, and can be side-by-side compatible (i.e. with the same class definitions) with protobuf-net if you want to try contract-based binary serialization (giving you a flat file serializer without any effort).

Most probably, you didn't install any SQL Server Engine service. If no SQL Server engine is installed, no service will appear in the SQL Server Configuration Manager tool. Consider that the packages SQLManagementStudio_Architecture_Language.exe and SQLEXPR_Architecture_Language.exe, available in the Microsoft site contain, respectively only the Management Studio GUI Tools and the SQL Server engine.

If you want to have a full featured SQL Server installation, with the database engine and Management Studio, download the installer file of SQL Server with Advanced Services. Moreover, to have a sample database in order to perform some local tests, use the Adventure Works database.

Considering the package of SQL Server with Advanced Services, at the beginning at the installation you should see something like this (the screenshot below is about SQL Server 2008 Express, but the feature selection is very similar). The checkbox next to "Database Engine Services" must be checked. In the next steps, you will be able to configure the instance settings and other options.

Execute again the installation process and select the database engine services in the feature selection step. At the end of the installation, you should be able to see the SQL Server services in the SQL Server Configuration Manager.

I solved the same problem without the temp table/view and with dataframe functions.

Of course I found that only one format works with this solution and that's yyyy-MM-DD.

For example:

val df = sc.parallelize(Seq("2016-08-26")).toDF("Id")
val df2 = df.withColumn("Timestamp", (col("Id").cast("timestamp")))
val df3 = df2.withColumn("Date", (col("Id").cast("date")))

df3.printSchema

root
 |-- Id: string (nullable = true)
 |-- Timestamp: timestamp (nullable = true)
 |-- Date: date (nullable = true)

df3.show

+----------+--------------------+----------+
|        Id|           Timestamp|      Date|
+----------+--------------------+----------+
|2016-08-26|2016-08-26 00:00:...|2016-08-26|
+----------+--------------------+----------+

The timestamp of course has 00:00:00.0 as a time value.

Further to Stephen Weinberg's answer, I have since implemented a handy tool called iojson, which helps to populate data to an existing object easily as well as encoding the existing object to a JSON string. A iojson middleware is also provided to work with other middlewares. More examples can be found at https://github.com/junhsieh/iojson

Example:

func main() {
    jsonStr := `{"Status":true,"ErrArr":[],"ObjArr":[{"Name":"My luxury car","ItemArr":[{"Name":"Bag"},{"Name":"Pen"}]}],"ObjMap":{}}`

    car := NewCar()

    i := iojson.NewIOJSON()

    if err := i.Decode(strings.NewReader(jsonStr)); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    }

    // populating data to a live car object.
    if v, err := i.GetObjFromArr(0, car); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    } else {
        fmt.Printf("car (original): %s\n", car.GetName())
        fmt.Printf("car (returned): %s\n", v.(*Car).GetName())

        for k, item := range car.ItemArr {
            fmt.Printf("ItemArr[%d] of car (original): %s\n", k, item.GetName())
        }

        for k, item := range v.(*Car).ItemArr {
            fmt.Printf("ItemArr[%d] of car (returned): %s\n", k, item.GetName())
        }
    }
}

Sample output:

car (original): My luxury car
car (returned): My luxury car
ItemArr[0] of car (original): Bag
ItemArr[1] of car (original): Pen
ItemArr[0] of car (returned): Bag
ItemArr[1] of car (returned): Pen

You can try ng-file-upload angularjs plugin (instead of ng-upload).

It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.

html

<!-- Note: MUST BE PLACED BEFORE angular.js-->
<script src="ng-file-upload-shim.min.js"></script> 
<script src="angular.min.js"></script>
<script src="ng-file-upload.min.js"></script> 

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var file = $files[i];
      $scope.upload = $upload.upload({
        url: 'server/upload/url', //upload.php script, node.js route, or servlet url
        data: {myObj: $scope.myModelObj},
        file: file,
      }).progress(function(evt) {
        console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
      }).then(function(response) {
        var data = response.data;
        // file is uploaded successfully
        console.log(data);
      });
    }
  };
}];

Don't know the nature of your app, but I have seen this error manifested multiple times because of a connection pool leak, so that would be worth checking out. On Linux, socket connections consume file descriptors as well as file system files. Just a thought.

Viewgroup inherits properties of views and does more with other views and viewgroup.

See the Android API: http://developer.android.com/reference/android/view/ViewGroup.html

For future reference, you can get help for any command by using the /? switch, which should explain what switches do what.

According to the set /? screen, the format for set /p is SET /P variable=[promptString] which would indicate that the p in /p is "prompt." It just prints in your example because <nul passes in a nul character which immediately ends the prompt so it just acts like it's printing. It's still technically prompting for input, it's just immediately receiving it.

/L in for /L generates a List of numbers.

I used the Visual Studio 2008 Uninstall tool and it worked fine for me.

You can use this tool to uninstall Visual Studio 2008 official release and Visual Studio 2008 Release candidate (Only English version).

Found here, on the MSDN Forum: MSDN forum topic.

I found this answer here

Be sure you run the tool with admin-rights.

There are some use cases suitable to UDP transport and others suitable to TCP transport.

The use case also dictates encoding settings for the video. When broadcasting soccer match focus is on quality and for video conference focus is on latency.

When using multicast to deliver video to your customers then UDP is used.

Requirement for multicast is expensive networking hardware between broadcasting server and customer. In practice this means if your company owns network infrastructure you can use UDP and multicast for live video streaming. Even then quality-of-service is also implemented to mark video packets and prioritize them so no packet loss happens.

Multicast will simplify broadcasting software because network hardware will handle distributing packets to customers. Customers subscribe to multicast channels and network will reconfigure to route packets to new subscriber. By default all channels are available to all customers and can be optimally routed.

This workflow places dificulty on authorization process. Network hardware does not differentiate subscribed users from other users. Solution to authorization is in encrypting video content and enabling decryption in player software when subscription is valid.

Unicast (TCP) workflow allows server to check client's credentials and only allow valid subscriptions. Even allow only certain number of simultaneous connections.

Multicast is not enabled over internet.

For delivering video over internet TCP must be used. When UDP is used developers end up re-implementing packet re-transmission, for eg. Bittorrent p2p live protocol.

"If you use TCP, the OS must buffer the unacknowledged segments for every client. This is undesirable, particularly in the case of live events".

This buffer must exist in some form. Same is true for jitter buffer on player side. It is called "socket buffer" and server software can know when this buffer is full and discard proper video frames for live streams. It is better to use unicast/TCP method because server software can implement proper frame dropping logic. Random missing packets in UDP case will just create bad user experience. like in this video: http://tinypic.com/r/2qn89xz/9

"IP multicast significantly reduces video bandwidth requirements for large audiences"

This is true for private networks, Multicast is not enabled over internet.

"Note that if TCP loses too many packets, the connection dies; thus, UDP gives you much more control for this application since UDP doesn't care about network transport layer drops."

UDP also doesn't care about dropping entire frames or group-of-frames so it does not give any more control over user experience.

"Usually a video stream is somewhat fault tolerant"

Encoded video is not fault tolerant. When transmitted over unreliable transport then forward error correction is added to video container. Good example is MPEG-TS container used in satellite video broadcast that carry several audio, video, EPG, etc. streams. This is necessary as satellite link is not duplex communication, meaning receiver can't request re-transmission of lost packets.

When you have duplex communication available it is always better to re-transmit data only to clients having packet loss then to include overhead of forward-error-correction in stream sent to all clients.

In any case lost packets are unacceptable. Dropped frames are ok in exceptional cases when bandwidth is hindered.

The result of missing packets are artifacts like this one:

Some decoders can break on streams missing packets in critical places.

You can di this:

#axs[1].plot(clust_data[:,0],clust_data[:,1]) # Remove this if you don't need it
axs[1].axis("off")  # This will leave the table alone in the window 

use <sys/time.h>

struct timeval tp;
gettimeofday(&tp, NULL);
long int ms = tp.tv_sec * 1000 + tp.tv_usec / 1000;

Open Ports Scanner works for me.

I say a website can be a web application, but more often a website has multiple web applications. the relationship between the two is one of composition: website composed of applications.

a dating site might have a photo upload web application, a calendar one so you can mark when you're dating who.

These applications are embedded throughout the website.

From a controller or view - use the following to display the version:

<?php
   echo CI_VERSION;
?>

It's basically a shorthand. So instead of having to write:

this.props.dispatch(toggleTodo(id));

You would use mapDispatchToProps as shown in your example code, and then elsewhere write:

this.props.onTodoClick(id);

or more likely in this case, you'd have that as the event handler:

<MyComponent onClick={this.props.onTodoClick} />

There's a helpful video by Dan Abramov on this here: https://egghead.io/lessons/javascript-redux-generating-containers-with-connect-from-react-redux-visibletodolist

The top-ranked solution (by Mizbah Ahsan) is not quite right ...but is close. If you apply draggable() to the modal dialog element, the browser window scroll bars will drag around the screen as you drag the modal dialog. The way to fix that is to apply draggable() to the modal-dialog class instead:

$(".modal-dialog").draggable({
    handle: ".modal-header"
});

Thanks!

The code below is how to detect almost all currently pressed keys, not just the Shift key.

private KeyMessageFilter m_filter = new KeyMessageFilter();

private void Form1_Load(object sender, EventArgs e)
{
    Application.AddMessageFilter(m_filter);
}


public class KeyMessageFilter : IMessageFilter
{
    private const int WM_KEYDOWN = 0x0100;
    private const int WM_KEYUP = 0x0101;
    private bool m_keyPressed = false;

    private Dictionary<Keys, bool> m_keyTable = new Dictionary<Keys, bool>();

    public Dictionary<Keys, bool> KeyTable
    {
        get { return m_keyTable; }
        private set { m_keyTable = value; }
    }

    public bool IsKeyPressed()
    {
        return m_keyPressed;
    }

    public bool IsKeyPressed(Keys k)
    {
        bool pressed = false;

        if (KeyTable.TryGetValue(k, out pressed))
        {
            return pressed;
        }

        return false;
    }

    public bool PreFilterMessage(ref Message m)
    {
        if (m.Msg == WM_KEYDOWN)
        {
            KeyTable[(Keys)m.WParam] = true;

            m_keyPressed = true;
        }

        if (m.Msg == WM_KEYUP)
        {
            KeyTable[(Keys)m.WParam] = false;

            m_keyPressed = false;
        }

        return false;
    }
}

HTML event handler code behaves like the body of a JavaScript function. Many languages such as C or Perl implicitly return the value of the last expression evaluated in the function body. JavaScript doesn't, it discards it and returns undefined unless you write an explicit returnEXPR.

To display a dialog or a toaster in a thread, the most concise way is to use the Activity object.

For example:

new Thread(new Runnable() {
    @Override
    public void run() {
        myActivity.runOnUiThread(new Runnable() {
            public void run() {
                myActivity.this.processingWaitDialog = new ProgressDialog(myActivity.this.getContext());
                myActivity.this.processingWaitDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
                myActivity.this.processingWaitDialog.setMessage("abc");
                myActivity.this.processingWaitDialog.setIndeterminate(true);
                myActivity.this.processingWaitDialog.show();
            }
        });
        expenseClassify.serverPost(
                new AsyncOperationCallback() {
                    public void operationCompleted(Object sender) {
                        myActivity.runOnUiThread(new Runnable() {
                            public void run() {
                                if (myActivity.this.processingWaitDialog != null 
                                        && myActivity.this.processingWaitDialog.isShowing()) {
                                    myActivity.this.processingWaitDialog.dismiss();
                                    myActivity.this.processingWaitDialog = null;
                                }
                            }
                        }); // .runOnUiThread(new Runnable()

I'm not aware of OpenCV but looking at the problem logically I think you could differentiate between bottle and can by changing the image which you are looking for i.e. Coca Cola. You should incorporate till top portion of can as in case of can there is silver lining at top of coca cola and in case of bottle there will be no such silver lining.

But obviously this algorithm will fail in cases where top of can is hidden, but in such case even human will not be able to differentiate between the two (if only coca cola portion of bottle/can is visible)

While I find most answers here quite correct, many of them contain unnecessary Bashisms. POSIX parameter expansion gives you all you need:

[ "${host#user}" != "${host}" ]

and

[ "${host#node}" != "${host}" ]

${var#expr} strips the smallest prefix matching expr from ${var} and returns that. Hence if ${host} does not start with user (node), ${host#user} (${host#node}) is the same as ${host}.

expr allows fnmatch() wildcards, thus ${host#node??} and friends also work.

$ck=2016-09-13 14:12:33;
$endtime = date('H-i-s', strtotime("+05 minutes", strtotime($ck)));  

The only way I've figured out how to do this is to have two properties for my class. One as the boolean for the programming API which is not included in the mapping. It's getter and setter reference a private char variable which is Y/N. I then have another protected property which is included in the hibernate mapping and it's getters and setters reference the private char variable directly.

EDIT: As has been pointed out there are other solutions that are directly built into Hibernate. I'm leaving this answer because it can work in situations where you're working with a legacy field that doesn't play nice with the built in options. On top of that there are no serious negative consequences to this approach.

None of the answers worked for me, but this is what finally worked after I set:

android:fitsSystemWindows="false"

In parent activity layout file it's not suggested at many places but it's work for me and saves my day

If you highlight the method Assert.assertEquals(val1, val2) and hit Ctrl + Shift + M (Add Import), it will add it as a static import, at least in Eclipse 3.4.

Here's the .gitignore that GitHub uses by default for new Xcode repositories:

https://github.com/github/gitignore/blob/master/Objective-C.gitignore

It's likely to be reasonably correct at any given time.

I was facing the same issue with jenkins ssh slave 'jenkinsci/ssh-slave'. However, my case was a bit complicated because it was necessary to pass an argument which contained spaces. I've managed to do it like below (entrypoint in dockerfile is in exec form):

command: ["some argument with space which should be treated as one"]

You can use these options as well, either use \footnotesize or \tiny. This would really help in fitting big tables.

About this, java declares that on Windows 10, Edge browser does not support plugins, so it will NOT run java. (see https://www.java.com/it/download/win10.jsp --> only visible with edge in win10) It also reports a notice: java is not officially supported yet in Windows 10. (see https://www.java.com/it/download/faq/win10_faq.xml)

Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z] or [0-9-]), OR escape it (e.g. [a-z\-0-9]) in order to add "hyphen" to your class.

It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.

(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)

Great question!

Defining an Android Mulitline EditText Field is done via the inputType=”textMultiline”. Unfortunately the text looks strangely aligned. To solve that also use the gravity=”left|top” attribute.

<EditText

   android:layout_height="match_parent"
   android:ems="10"

One of the reasons for me getting an error was the file name make sure the file name is Dockerfile So i figured it out, hope it might help someone.

The new constraint is fine, but if you need T being a value type too, use this:

protected T GetObject() {
    if (typeof(T).IsValueType || typeof(T) == typeof(string)) {
        return default(T);
    } else {
       return (T)Activator.CreateInstance(typeof(T));
    }
}

Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms.

In the Java context, we first need to make a distinction between "copying a value" and "copying an object".

int a = 1;
int b = a;     // copying a value
int[] s = new int[]{42};
int[] t = s;   // copying a value (the object reference for the array above)

StringBuffer sb = new StringBuffer("Hi mom");
               // copying an object.
StringBuffer sb2 = new StringBuffer(sb);

In short, an assignment of a reference to a variable whose type is a reference type is "copying a value" where the value is the object reference. To copy an object, something needs to use new, either explicitly or under the hood.

Now for "shallow" versus "deep" copying of objects. Shallow copying generally means copying only one level of an object, while deep copying generally means copying more than one level. The problem is in deciding what we mean by a level. Consider this:

public class Example {
    public int foo;
    public int[] bar;
    public Example() { };
    public Example(int foo, int[] bar) { this.foo = foo; this.bar = bar; };
}

Example eg1 = new Example(1, new int[]{1, 2});
Example eg2 = ... 

The normal interpretation is that a "shallow" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to the same array as in the original; e.g.

Example eg2 = new Example(eg1.foo, eg1.bar);

The normal interpretation of a "deep" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to a copy of the original array; e.g.

Example eg2 = new Example(eg1.foo, Arrays.copy(eg1.bar));

(People coming from a C / C++ background might say that a reference assignment produces a shallow copy. However, that's not what we normally mean by shallow copying in the Java context ...)

Two more questions / areas of uncertainty exist:

• How deep is deep? Does it stop at two levels? Three levels? Does it mean the whole graph of connected objects?

• What about encapsulated data types; e.g. a String? A String is actually not just one object. In fact, it is an "object" with some scalar fields, and a reference to an array of characters. However, the array of characters is completely hidden by the API. So, when we talk about copying a String, does it make sense to call it a "shallow" copy or a "deep" copy? Or should we just call it a copy?

Finally, clone. Clone is a method that exists on all classes (and arrays) that is generally thought to produce a copy of the target object. However:

• The specification of this method deliberately does not say whether this is a shallow or deep copy (assuming that is a meaningful distinction).

• In fact, the specification does not even specifically state that clone produces a new object.

Here's what the javadoc says:

"Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression x.clone() != x will be true, and that the expression x.clone().getClass() == x.getClass() will be true, but these are not absolute requirements. While it is typically the case that x.clone().equals(x) will be true, this is not an absolute requirement."

Note, that this is saying that at one extreme the clone might be the target object, and at the other extreme the clone might not equal the original. And this assumes that clone is even supported.

In short, clone potentially means something different for every Java class.

Some people argue (as @supercat does in comments) that the Java clone() method is broken. But I think the correct conclusion is that the concept of clone is broken in the context of OO. AFAIK, it is impossible to develop a unified model of cloning that is consistent and usable across all object types.

The Content-Type header is just used as info for your application. The browser doesn't care what it is. The browser just returns you the data from the AJAX call. If you want to parse it as JSON, you need to do that on your own.

The header is there so your app can detect what data was returned and how it should handle it. You need to look at the header, and if it's application/json then parse it as JSON.

This is actually how jQuery works. If you don't tell it what to do with the result, it uses the Content-Type to detect what to do with it.

I think this issue is similar to mine:

1. Connect to MySQL
2. End MySQL service (should not quit node script)
3. Start MySQL service, Node reconnects to MySQL
4. Query the DB -> FAIL (Cannot enqueue Query after fatal error.)

I solved this issue by recreating a new connection with the use of promises (q).

mysql-con.js

'use strict';
var config          = require('./../config.js');
var colors          = require('colors');
var mysql           = require('mysql');
var q               = require('q');
var MySQLConnection = {};

MySQLConnection.connect = function(){
    var d = q.defer();
    MySQLConnection.connection = mysql.createConnection({
        host                : 'localhost',
        user                : 'root',
        password            : 'password',
        database            : 'database'
    });

    MySQLConnection.connection.connect(function (err) {
        if(err) {
            console.log('Not connected '.red, err.toString().red, ' RETRYING...'.blue);
            d.reject();
        } else {
            console.log('Connected to Mysql. Exporting..'.blue);
            d.resolve(MySQLConnection.connection);
        }
    });
    return d.promise;
};

module.exports = MySQLConnection;

mysqlAPI.js

var colors          = require('colors');
var mysqlCon        = require('./mysql-con.js');
mysqlCon.connect().then(function(con){
   console.log('connected!');
    mysql = con;
    mysql.on('error', function (err, result) {
        console.log('error occurred. Reconneting...'.purple);
        mysqlAPI.reconnect();
    });
    mysql.query('SELECT 1 + 1 AS solution', function (err, results) {
            if(err) console.log('err',err);
            console.log('Works bro ',results);
    });
});

mysqlAPI.reconnect = function(){
    mysqlCon.connect().then(function(con){
      console.log("connected. getting new reference");
        mysql = con;
        mysql.on('error', function (err, result) {
            mysqlAPI.reconnect();
        });
    }, function (error) {
      console.log("try again");
        setTimeout(mysqlAPI.reconnect, 2000);
    });
};

I hope this helps.

You can do it with anchor tags using css3 :target pseudo-selector, this selector is going to be triggered when the element with the same id as the hash of the current URL get an match. Example

Knowing this, we can combine this technique with the use of proximity selectors like "+" and "~" to select any other element through the target element who id get match with the hash of the current url. An example of this would be something like what you are asking.

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

Here is a simple example of adding an image to a JFrame:

frame.add(new JLabel(new ImageIcon("Path/To/Your/Image.png")));

This is the best answer: https://stackoverflow.com/a/4027726/2159089

in linux:

export PYTHONIOENCODING=utf-8

so sys.stdout.encoding is OK.

The execution process is really confusing with recursive CTE, I found the best answer at https://technet.microsoft.com/en-us/library/ms186243(v=sql.105).aspx and the abstract of the CTE execution process is as below.

The semantics of the recursive execution is as follows:

1. Split the CTE expression into anchor and recursive members.
2. Run the anchor member(s) creating the first invocation or base result set (T0).
3. Run the recursive member(s) with Ti as an input and Ti+1 as an output.
4. Repeat step 3 until an empty set is returned.
5. Return the result set. This is a UNION ALL of T0 to Tn.

It bears mentioning that nokogiri itself ships with a command line tool, which should be installed with gem install nokogiri.

You might find this blog post useful.

You may want to use something like this:

NSDateComponents *components;
NSInteger days;

components = [[NSCalendar currentCalendar] components: NSDayCalendarUnit 
        fromDate: startDate toDate: endDate options: 0];
days = [components day];

I believe this method accounts for situations such as dates that span a change in daylight savings.

Try this:

String result = "34.1 -118.33\n<!--ABCDEFG-->";
result = result.substring(0, result.indexOf("\n"));

You can provide more flexibility to your users by provide Browser Button to them

Private Sub btn_browser_file_Click()

    .Title = "Please select a folder to list Files from"
    .InitialFileName = InitialFoldr$
    .Show
    Range("H13").Activate
    If .SelectedItems.Count <> 0 Then
        xDirect$ = .SelectedItems(1) & "\"
         Range("h12").Value = xDirect$
        xFname$ = Dir(xDirect$, 7)
        Do While xFname$ <> ""
         If (Format(FileDateTime(xDirect$ & "\" & xFname$), "MM/DD/YYYY") > Format(Range("H10").Value, "MM/DD/YYYY")) Then
            ActiveCell.Offset(xRow) = xFname$
            xRow = xRow + 1
            xFname$ = Dir
            Else
            xFname$ = Dir
            xRow = xRow
        End If
        Loop
    End If
End With

with this piece of code you can achieve this, easily. Tested code

Open a command prompt.

Go to the directory where you have your .java files

Create a directory build

Run java compilation from the command line

javac -d ./build *.java

if there are no errors, in the build directory you should have your class tree

move to the build directory and do a

jar cvf YourJar.jar *

For adding manifest check jar command line switches

window.location = mypage.href is a direct command for the browser to dump it's contents and start loading up some more. So for better clarification, here's what's happening in your PHP script:

echo '<script type="text/javascript">'; 
echo 'alert("review your answer");'; 
echo 'window.location = "index.php";';
echo '</script>';

1) prepare to accept a modification or addition to the current Javascript cache. 2) show the alert 3) dump everything in browser memory and get ready for some more (albeit an older method of loading a new URL (AND NOTICE that there are no "\n" (new line) indicators between the lines and is therefore causing some havoc in the JS decoder.

Let me suggest that you do this another way..

echo '<script type="text/javascript">\n'; 
echo 'alert("review your answer");\n'; 
echo 'document.location.href = "index.php";\n';
echo '</script>\n';

1) prepare to accept a modification or addition to the current Javascript cache. 2) show the alert 3) dump everything in browser memory and get ready for some more (in a better fashion than before) And WOW - it all works because the JS decoder can see that each command is anow a new line.

Best of luck!

Use JQuery keydown event.

$(document).keypress(function(){
    if(event.which == 70){  //f
        console.log("You have payed respect");
    }
});

In JS; keyboard keys are identified by Javascript keycodes

i had this problem too . i was running different solutions at the same time using visual studio , when closing other solutions and running just the target solution , it worked fine without that error .

I should this On Windows, environment variable expansion is %BUILD_NUMBER%

There are two ways to know which rules are overriding:

1. Search the property in the Filter box at the top of the Styles tab. It will show all the rules containing that property, with the property highlighted in yellow.

   

2. Look in the Computed tab to find the same property type, and then expand that to see the source of the various rules that are trying to apply that property.

   

Can you invert your regex so split by the non operation characters?

String ops[] = string.split("[a-z]")
// ops == [+, -, *, /, <, >, >=, <=, == ]   

This obviously doesn't return the variables in the array. Maybe you can interleave two splits (one by the operators, one by the variables)

The noob way to do this:

SELECT field1, field2 FROM table WHERE field1 = TRUE OR field2 = TRUE

You can manage this information properly at the programming language only doing an if-else.

Example in ASP/JavaScript

// Code to retrieve the ADODB.Recordset
if (rs("field1")) {
   do_the_stuff_a();
}
if (rs("field2")) {
   do_the_stuff_b();
}
rs.MoveNext();

You can use the method Path.GetFileName(yourFileName); (MSDN) to just get the name of the file.

If you are counting letters, the above solution will fail for some unicode symbols. For example for these 5 characters sample.length() will return 6 instead of 5:

String sample = "\u760c\u0444\u03b3\u03b5\ud800\udf45"; // ???e

The codePointCount function was introduced in Java 1.5 and I understand gives better results for glyphs etc

sample.codePointCount(0, sample.length()) // returns 5

We all know that Java does not provide anything like the unsigned keyword. Moreover, a byte primitive according to the Java's spec represents a value between -128 and 127. For instance, if a byte is cast to an int Java will interpret the first bit as the sign and use sign extension.

Then, how to convert a byte greater than 127 to its binary string representation ??

Nothing prevents you from viewing a byte simply as 8-bits and interpret those bits as a value between 0 and 255. Also, you need to keep in mind that there's nothing you can do to force your interpretation upon someone else's method. If a method accepts a byte, then that method accepts a value between -128 and 127 unless explicitly stated otherwise.

So the best way to solve this is convert the byte value to an int value by calling the Byte.toUnsignedInt() method or casting it as a int primitive (int) signedByte & 0xFF. Here you have an example:

public class BinaryOperations
{
    public static void main(String[] args)
    {
        byte forbiddenZeroBit = (byte) 0x80;

        buffer[0] = (byte) (forbiddenZeroBit & 0xFF);
        buffer[1] = (byte) ((forbiddenZeroBit | (49 << 1)) & 0xFF);
        buffer[2] = (byte) 96;
        buffer[3] = (byte) 234;

        System.out.println("8-bit header:");
        printBynary(buffer);
    }

    public static void printBuffer(byte[] buffer)
    {
        for (byte num : buffer) {
            printBynary(num);
        }
    }

    public static void printBynary(byte num)
    {
        int aux = Byte.toUnsignedInt(num);
        // int aux = (int) num & 0xFF; 
        String binary = String.format("%8s', Integer.toBinaryString(aux)).replace(' ', '0');
        System.out.println(binary);
    }
}

Output

8-bit header:
10000000
11100010
01100000
11101010

Out-File defaults to unicode encoding which is why you are seeing the behavior you are. Use -Encoding Ascii to change this behavior. In your case

Out-File -Encoding Ascii -append textfile.txt. 

Add-Content uses Ascii and also appends by default.

"This is a test" | Add-Content textfile.txt.

As for the lack of newline: You did not send a newline so it will not write one to file.

this is what worked for me (yes I was having the same problem) were is says something like java -Xmx3G -Xms3G put java -Xmx1024M so the run.bat should look like java -Xmx1024M -jar craftbukkit.jar -o false PAUSE

By adding the attribute readonly (or readonly="readonly") to the input field you should prevent anyone typing anything in it, but still be able to launch a click event on it.

This is also usefull in non-mobile devices as you use a date/time picker

In General to get rid of

Object of class stdClass could not be converted to string.

try to use echo '<pre>'; print_r($sql_query); for my SQL Query got the result as

stdClass Object
(
    [num_rows] => 1
    [row] => Array
        (
            [option_id] => 2
            [type] => select
            [sort_order] => 0
        )

    [rows] => Array
        (
            [0] => Array
                (
                    [option_id] => 2
                    [type] => select
                    [sort_order] => 0
                )

        )

)

In order to acces there are different methods E.g.: num_rows, row, rows

echo $query2->row['option_id'];

Will give the result as 2
