I tried something similar and was able to reproduce the problem (IndexOutOfBoundsException). Below are my findings:

1) The implementation of the Collections.copy(destList, sourceList) first checks the size of the destination list by calling the size() method. Since the call to the size() method will always return the number of elements in the list (0 in this case), the constructor ArrayList(capacity) ensures only the initial capacity of the backing array and this does not have any relation to the size of the list. Hence we always get IndexOutOfBoundsException.

2) A relatively simple way is to use the constructor that takes a collection as its argument:

List<SomeBean> wsListCopy=new ArrayList<SomeBean>(wsList);  

You can use this function:

function mapMap(map, fn) {
  return new Map(Array.from(map, ([key, value]) => [key, fn(value, key, map)]));
}

usage:

var map1 = new Map([["A", 2], ["B", 3], ["C", 4]]);

var map2 = mapMap(map1, v => v * v);

console.log(map1, map2);
/*
Map { A ? 2, B ? 3, C ? 4 }
Map { A ? 4, B ? 9, C ? 16 }
*/

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

Cancelling Angular $http Ajax with the timeout property doesn't work in Angular 1.3.15. For those that cannot wait for this to be fixed I'm sharing a jQuery Ajax solution wrapped in Angular.

The solution involves two services:

• HttpService (a wrapper around the jQuery Ajax function);
• PendingRequestsService (tracks the pending/open Ajax requests)

Here goes the PendingRequestsService service:

    (function (angular) {
    'use strict';
    var app = angular.module('app');
    app.service('PendingRequestsService', ["$log", function ($log) {            
        var $this = this;
        var pending = [];
        $this.add = function (request) {
            pending.push(request);
        };
        $this.remove = function (request) {
            pending = _.filter(pending, function (p) {
                return p.url !== request;
            });
        };
        $this.cancelAll = function () {
            angular.forEach(pending, function (p) {
                p.xhr.abort();
                p.deferred.reject();
            });
            pending.length = 0;
        };
    }]);})(window.angular);

The HttpService service:

     (function (angular) {
        'use strict';
        var app = angular.module('app');
        app.service('HttpService', ['$http', '$q', "$log", 'PendingRequestsService', function ($http, $q, $log, pendingRequests) {
            this.post = function (url, params) {
                var deferred = $q.defer();
                var xhr = $.ASI.callMethod({
                    url: url,
                    data: params,
                    error: function() {
                        $log.log("ajax error");
                    }
                });
                pendingRequests.add({
                    url: url,
                    xhr: xhr,
                    deferred: deferred
                });            
                xhr.done(function (data, textStatus, jqXhr) {                                    
                        deferred.resolve(data);
                    })
                    .fail(function (jqXhr, textStatus, errorThrown) {
                        deferred.reject(errorThrown);
                    }).always(function (dataOrjqXhr, textStatus, jqXhrErrorThrown) {
                        //Once a request has failed or succeeded, remove it from the pending list
                        pendingRequests.remove(url);
                    });
                return deferred.promise;
            }
        }]);
    })(window.angular);

Later in your service when you are loading data you would use the HttpService instead of $http:

(function (angular) {

    angular.module('app').service('dataService', ["HttpService", function (httpService) {

        this.getResources = function (params) {

            return httpService.post('/serverMethod', { param: params });

        };
    }]);

})(window.angular);

Later in your code you would like to load the data:

(function (angular) {

var app = angular.module('app');

app.controller('YourController', ["DataService", "PendingRequestsService", function (httpService, pendingRequestsService) {

    dataService
    .getResources(params)
    .then(function (data) {    
    // do stuff    
    });    

    ...

    // later that day cancel requests    
    pendingRequestsService.cancelAll();
}]);

})(window.angular);

You can also use regex.

let trimmedString = myString.stringByReplacingOccurrencesOfString("\\s", withString: "", options: NSStringCompareOptions.RegularExpressionSearch, range: nil)

Don't forget to use apply plugin: 'com.android.library' in your build.gradle instead of apply plugin: 'com.android.application'

Apache's errorlog will explain why you get a permission denied. Also, serverfault.com is a better forum for a question like this.

If the error log simply says "permission denied", su to the user that the webserver is running as and try to read from the file in question. So for example:

sudo -s
su - nobody
cd /
cd /home
cd user
cd xxx
cat index.html

See if one of those gives you the "permission denied" error.

This code will remove the indentation and list bullets.

ul {
    padding: 0;
    list-style-type: none;
}

Thought I would add an answer to this one, since my problem was simple but hard to notice. In particular I had copy/pasted an existing meta-data element when creating my com.google.firebase.messaging.default_notification_icon, which used an android:value tag to specify its value. This will not work for the notification icon, and once I changed it to android:resource everything worked as expected.

you can install it using this command line

 echo @php "%~dp0composer.phar" %* > composer.bat

Import moment js:

var fulldate = new Date(1370001284000);
var converted_date = moment(fulldate).format(");

I resolved this same problem in python using flask and with this library. flask_cors

The const variable specifies whether a variable is modifiable or not. The constant value assigned will be used each time the variable is referenced. The value assigned cannot be modified during program execution.

Bjarne Stroustrup's explanation sums it up briefly:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects.

A const variable has to be declared within the class, but it cannot be defined in it. We need to define the const variable outside the class.

T1() : t( 100 ){}

Here the assignment t = 100 happens in initializer list, much before the class initilization occurs.

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

For anyone who needs to run a program in the background "without PHP waiting for it to finish" do this:

 pclose(popen("start /B ".$cmd, "r")); 

where $cmd is the string command for the program that you need to run (e.g. $cmd can equal notepad.exe or node Path\to\server.js).

Source: https://www.php.net/manual/en/function.exec.php (see Arno van den Brink's note in the section titled "User Contributed Notes").

the simplest way I can think to explain this is by using some pseudo code

so

list of 1, 2 ,3
for each item in list
    templist.Add(item)
    for each item2 in list
        if item2 is Not item
            templist.add(item)
               for each item3 in list
                   if item2 is Not item
                      templist.add(item)

                   end if
               Next
            end if

    Next
    permanentListofPermutaitons,add(templist)
    tempList.Clear()
Next

Now obviously this is not the most flexible way to do this, and doing it recursively would be a lot more functional by my tired sunday night brain doesn't want to think about that at this moment. If no ones put up a recursive version by the morning I'll do one.

break is to break out of a loop like for, while, switch etc which you don't have here, you need to use return to break the execution flow of the current function and return to the caller.

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        requestAnimFrame(loop);
        if (game == 1) {
           return
        }
    }
}

Note: This does not cover the logic behind the if condition or when to return from the method, for that we need to have more context regarding the drawAllEnemies and requestAnimFrame method as well as how game value is updated

package - takes the compiled code and package it in its distributable format, such as a JAR or WAR file. install - install the package into the local repository, for use as a dependency in other projects locally

After reading a bunch of people's comments online about this, my first reaction was that this is basically one of those really unimportant debates. However, my initial interest was to find out the right format so I could be consistent with my file naming practice.

Long story short, the creator of YAML are saying .yaml, but personally I keep doing .yml. That just makes more sense to me. So I went on the journey to find affirmation and soon enough, I realise that docker uses .yml everywhere. I've been writing docker-compose.yml files all this time, while you keep seeing in kubernetes' docs kubectl apply -f *.yaml...

So, in conclusion, both formats are obviously accepted and if you are on the other end, (ie: writing systems that receive a YAML file as input) you should allow for both. That seems like another snake case versus camel case thingy...

keras.callbacks.TensorBoard(log_dir='./Graph', histogram_freq=0,  
          write_graph=True, write_images=True)

This line creates a Callback Tensorboard object, you should capture that object and give it to the fit function of your model.

tbCallBack = keras.callbacks.TensorBoard(log_dir='./Graph', histogram_freq=0, write_graph=True, write_images=True)
...
model.fit(...inputs and parameters..., callbacks=[tbCallBack])

This way you gave your callback object to the function. It will be run during the training and will output files that can be used with tensorboard.

If you want to visualize the files created during training, run in your terminal

tensorboard --logdir path_to_current_dir/Graph 

Hope this helps !

I thought it should be

std::transform( map.begin(), map.end(), 
                   std::back_inserter(vec), 
                   boost::bind(&MapT::value_type::first,_1) ); 

One of the simplest way: use Link as follows:

import { Link } from 'react-router-dom';

<Link to={`your-path`} activeClassName="current">{your-link-name}</Link>

If we want to cover the whole div section as link:

 <div>
     <Card as={Link} to={'path-name'}>
         .... 
           card content here
         ....
     </Card>
 </div>

A node is the generic name for any type of object in the DOM hierarchy. A node could be one of the built-in DOM elements such as document or document.body, it could be an HTML tag specified in the HTML such as <input> or <p> or it could be a text node that is created by the system to hold a block of text inside another element. So, in a nutshell, a node is any DOM object.

An element is one specific type of node as there are many other types of nodes (text nodes, comment nodes, document nodes, etc...).

The DOM consists of a hierarchy of nodes where each node can have a parent, a list of child nodes and a nextSibling and previousSibling. That structure forms a tree-like hierarchy. The document node has the html node as its child. The html node has its list of child nodes (the head node and the body node). The body node would have its list of child nodes (the top level elements in your HTML page) and so on.

So, a nodeList is simply an array-like list of nodes.

An element is a specific type of node, one that can be directly specified in the HTML with an HTML tag and can have properties like an id or a class. can have children, etc... There are other types of nodes such as comment nodes, text nodes, etc... with different characteristics. Each node has a property .nodeType which reports what type of node it is. You can see the various types of nodes here (diagram from MDN):

You can see an ELEMENT_NODE is one particular type of node where the nodeType property has a value of 1.

So document.getElementById("test") can only return one node and it's guaranteed to be an element (a specific type of node). Because of that it just returns the element rather than a list.

Since document.getElementsByClassName("para") can return more than one object, the designers chose to return a nodeList because that's the data type they created for a list of more than one node. Since these can only be elements (only elements typically have a class name), it's technically a nodeList that only has nodes of type element in it and the designers could have made a differently named collection that was an elementList, but they chose to use just one type of collection whether it had only elements in it or not.

EDIT: HTML5 defines an HTMLCollection which is a list of HTML Elements (not any node, only Elements). A number of properties or methods in HTML5 now return an HTMLCollection. While it is very similar in interface to a nodeList, a distinction is now made in that it only contains Elements, not any type of node.

The distinction between a nodeList and an HTMLCollection has little impact on how you use one (as far as I can tell), but the designers of HTML5 have now made that distinction.

For example, the element.children property returns a live HTMLCollection.

Use the following code fragment to hide the form on button click.

document.getElementById("your form id").style.display="none";

And the following code to display it:

document.getElementById("your form id").style.display="block";

Or you can use the same function for both purposes:

function asd(a)
{
    if(a==1)
        document.getElementById("asd").style.display="none";
    else
        document.getElementById("asd").style.display="block";
}

And the HTML:

<form id="asd">form </form>
<button onclick="asd(1)">Hide</button>
<button onclick="asd(2)">Show</button>

To fix this issue, do these steps:

1. Right click the Project name in Solution Explorer of Visual Studio
2. Select Set as StartUp Project from the menu
3. Re-run your project It should work!

If it did not work, be sure that you have set your start page. If your project is C# Windows Application or C# Console Application, try this:

1. Right click the Project name in Solution Explorer of Visual Studio
2. Select Properties
3. Select the Application tab
4. In the Output Type drop box
5. Select the correct application type of your project
6. Re-run your project and let me know if it won’t work.

If you have a polyfill for URLSearchParams or simply don't have to support Internet Explorer, that's what I would use like suggested in other answers here. If you don't want to depend on URLSearchParams, that's how I would do it:

function removeParameterFromUrl(url, parameter) {
  const replacer = (m, p1, p2) => (p1 === '?' && p2 === '&' ? '?' : p2 || '')
  return url.replace(new RegExp(`([?&])${parameter}=[^&#]+([&#])?`), replacer)
}

It will replace a parameter preceded by ? (p1) and followed by & (p2) with ? to make sure the list of parameters still starts with a question mark, otherwise, it will replace it with the next separator (p2): could be &, or #, or undefined which falls back to an empty string.

If you have android, you can install free app on phone (Wifi file Transfer) and enable ssl, port and other options for access and send data in both directions just start application and write in pc browser phone ip and port. enjoy!

You can overflow:hidden to your #content. Write like this:

#content
{
    min-width:700px;
    margin-left:10px;
    overflow:hidden;
    background-color:AppWorkspace;
}

This script logs all the file names and ids in the drive:

// Log the name and id of every file in the user's Drive
function listFiles() {
  var files = DriveApp.getFiles();
  while ( files.hasNext() ) {
    var file = files.next();
    Logger.log( file.getName() + ' ' + file.getId() );
  }
}  

Also, the "Files: list" page has a form at the end that lists the metadata of all the files in the drive, that can be used in case you need but a few ids.

In 2012, use the python requests library

>>> import requests
>>> 
>>> url = "http://download.thinkbroadband.com/10MB.zip"
>>> r = requests.get(url)
>>> print len(r.content)
10485760

You can run pip install requests to get it.

Requests has many advantages over the alternatives because the API is much simpler. This is especially true if you have to do authentication. urllib and urllib2 are pretty unintuitive and painful in this case.

2015-12-30

People have expressed admiration for the progress bar. It's cool, sure. There are several off-the-shelf solutions now, including tqdm:

from tqdm import tqdm
import requests

url = "http://download.thinkbroadband.com/10MB.zip"
response = requests.get(url, stream=True)

with open("10MB", "wb") as handle:
    for data in tqdm(response.iter_content()):
        handle.write(data)

This is essentially the implementation @kvance described 30 months ago.

Using font-face requires a little understanding of browser inconsistencies and may require some changes on the web server itself. First thing you have to do is check the console to see if/what messages are being generated. Is it a permissions issue or resource not found....?

Secondly because each browser is expecting a different font type I would use Font Squirrel to upload your font and then generate the additional files and CSS needed. http://www.fontsquirrel.com/fontface/generator

And finally, versions of FireFox and IE will not allow fonts to be loaded cross domain. You may need to modify your Apache config or .htaccess (Header set Access-Control-Allow-Origin "*")

In both: Anaconda prompt and the old cmd.exe, you change your directory by first changing to the drive you want, by simply writing its name followed by a ':', exe: F: , which will take you to the drive named 'F' on your machine. Then using the command cd to navigate your way inside that drive as you normally would.

From the root shell (e.g. adb shell), you can lock with:

echo mylockname >/sys/power/wake_lock    

After which the device will stay awake, until you do:

echo mylockname >/sys/power/wake_unlock    

With the same string for 'mylockname'.

Note that this will not prevent the screen from going black, but it will prevent the CPU from sleeping.

Note that /sys/power/wake_lock is read-write for user radio (1001) and group system (1000), and, of course, root.

A reference is here: http://lwn.net/Articles/479841/

Don't try to do this yourself if you're serious about getting edge cases right. So while they many naive/simple methods are theoretically exact, they can have nasty numerical behavior for nearly singular matrices. In particular you can get cancelation/round-off errors that cause you to get arbitrarily bad results.

A "correct" way is Gaussian elimination with row and column pivoting so that you're always dividing by the largest remaining numerical value. (This is also stable for NxN matrices.). Note that row pivoting alone doesn't catch all the bad cases.

However IMO implementing this right and fast is not worth your time - use a well tested library and there are a heap of header only ones.

I use the /^[a-z]+:[^:]+$/i regular expression for URL validation. See an example of my cross-browser InputKeyFilter code with URL validation.

Run eventvwr from the command line to see if it has recorded any Application errors.

This might give you an actual error message that is more useful.

I struggled with the idea of centralizing a global error handling routine in an MVC app before. I have a post on the ASP.NET forums.

It basically handles all your application errors in the global.asax without the need for an error controller, decorating with the [HandlerError] attribute, or fiddling with the customErrors node in the web.config.

Including "string.h" makes things easier. An easier way to tackle your problem is:

#include <string.h>
    char* createStr(){
    static char str[20] = "my";
    return str;
}
int main(){
    char a[20];
    strcpy(a,createStr()); //this will copy the returned value of createStr() into a[]
    printf("%s",a);
    return 0;
}

I modified Sanoj Dushmantha's answer to use sessionStorage instead of localStorage. However, despite the documentation, browsers will still store this data even after the browser is closed. To fix this issue, I am removing the scroll position after it is reset.

<script>
    document.addEventListener("DOMContentLoaded", function (event) {
        var scrollpos = sessionStorage.getItem('scrollpos');
        if (scrollpos) {
            window.scrollTo(0, scrollpos);
            sessionStorage.removeItem('scrollpos');
        }
    });

    window.addEventListener("beforeunload", function (e) {
        sessionStorage.setItem('scrollpos', window.scrollY);
    });
</script>

I had the same challenge. When I collapsed some menus I had on the left of my web app, the datatable would not resize. Adding "autoWidth": false duirng initialization worked for me.

$('#dataTable').DataTable({'autoWidth':false, ...});

If you want to fetch + merge, run

git pull

if you want simply to fetch :

git fetch

The issue with the null connection is related to the findBT() function. you must change the device name from "MattsBlueTooth" to your device name as well as confirm the UUID for your service/device. Use something like BLEScanner app to confrim both on Android.

now you can use rgba in CSS properties like this:

.class {
    background: rgba(0,0,0,0.5);
}

0.5 is the transparency, change the values according to your design.

My answer on this question might help you:

int finalHeight, finalWidth;
final ImageView iv = (ImageView)findViewById(R.id.scaled_image);
final TextView tv = (TextView)findViewById(R.id.size_label);
ViewTreeObserver vto = iv.getViewTreeObserver();
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
    public boolean onPreDraw() {
        iv.getViewTreeObserver().removeOnPreDrawListener(this);
        finalHeight = iv.getMeasuredHeight();
        finalWidth = iv.getMeasuredWidth();
        tv.setText("Height: " + finalHeight + " Width: " + finalWidth);
        return true;
    }
});

You can then add your image scaling work from within the onPreDraw() method.

You can try this:

var entryArray = Array.prototype.slice.call(entry)

The only valid answer would be the pause command.

Though this does not wait specifically for the 'ENTER' key, it waits for any key that is pressed.

And just in case you want it convenient for the user, pause is the best option.

For those of you who can't use the HtmlAgilityPack, .NETs XML reader is an option. This can fail on well formatted HTML though so always add a catch with regx as a backup. Note this is NOT fast, but it does provide a nice opportunity for old school step through debugging.

            Regex compressSpaces = new Regex(@"[\s\r\n]+");
            textOnly = tagRemove.Replace(content, string.Empty);
            textOnly = compressSpaces.Replace(textOnly, " ");
            cleaned = textOnly;

I do the following to work out which dependency cannot be found.

Run regedit.exe and navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion

Create the following:

LogFailures set value to 1 (DWORD)
LogResourceBinds set value to 1 (DWORD)
LogPath (String) set value to C:\FusionLog\

Now run your program and wait for it to raise Could not load file or assembly or one of its dependencies.

Using explorer, navigate to C:\FusionLog and there should be a folder containing logs for your program, showing which dependency is missing.

Note: Some people use FUSLOGVW.exe, which is a viewer for these Fusion Logs. On my machine it can be found in multiple places, including:

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.2 Tools\x64\FUSLOGVW.exe

I think you can try this for calling in from a class

 System.Web.HttpContext.Current.Server.MapPath("~/SignatureImages/");

*----------------Sorry I oversight, for static function already answered the question by adrift*

System.Web.Hosting.HostingEnvironment.MapPath("~/SignatureImages/");

Update

I got exception while using System.Web.Hosting.HostingEnvironment.MapPath("~/SignatureImages/");

Ex details : System.ArgumentException: The relative virtual path 'SignatureImages' is not allowed here. at System.Web.VirtualPath.FailIfRelativePath()

Solution (tested in static webmethod)

System.Web.HttpContext.Current.Server.MapPath("~/SignatureImages/"); Worked

If you updated Internet Explorer and began having technical problems, you can use the Compatibility View feature to emulate a previous version of Internet Explorer.

For instructions, see the section below that corresponds with your version. To find your version number, click Help > About Internet Explorer. Internet Explorer 11

To edit the Compatibility View list:

Open the desktop, and then tap or click the Internet Explorer icon on the taskbar.
Tap or click the Tools button (Image), and then tap or click Compatibility View settings.
To remove a website:
Click the website(s) where you would like to turn off Compatibility View, clicking Remove after each one.
To add a website:
Under Add this website, enter the website(s) where you would like to turn on Compatibility View, clicking Add after each one.

After "return" statement, you can't write any code(excluding try-finally block). Move your new activity codes before the "return" statements.

Once a dom element is created, the tag is immutable, I believe. You'd have to do something like this:

$(this).replaceWith($('<h5>' + this.innerHTML + '</h5>'));

Based on .NET 4.5

Sample code below

using System;

enum Importance
{
    None,
    Low,
    Medium,
    Critical
}

class Program
{
    static void Main()
    {
    // The input value.
    string value = "Medium";

    // An unitialized variable.
    Importance importance;

    // Call Enum.TryParse method.
    if (Enum.TryParse(value, out importance))
    {
        // We now have an enum type.
        Console.WriteLine(importance == Importance.Medium);
    }
    }
}

the behaviour of fixed elements (and absolute elements) as defined in CSS Spec:

They behave as they are detached from document, and placed in the nearest fixed/absolute positioned parent. (not a word by word quote)

This makes zindex calculation a bit complicated, I solved my problem (the same situation) by dynamically creating a container in body element and moving all such elements (which are class-ed as "my-fixed-ones" inside that body-level element)

Having an interest in this, I decided to test the suggested methods with the closest "apples to apples" test I could. I wrote a Console app, with the following code:

The results surprised me; they were consistent when run multiple times:

Generating 100000 arrays of data...
Test data generated.
Testing BinarySerializer...
BinaryFormatter: Serializing took 336.8392ms.
BinaryFormatter: Deserializing took 208.7527ms.

Testing ProtoBuf serializer...
ProtoBuf: Serializing took 2284.3827ms.
ProtoBuf: Deserializing took 2201.8072ms.

Testing NetSerializer serializer...
NetSerializer: Serializing took 2139.5424ms.
NetSerializer: Deserializing took 2113.7296ms.
Press any key to end.

Collecting these results, I decided to see if ProtoBuf or NetSerializer performed better with larger objects. I changed the collection count to 10,000 objects, but increased the size of the arrays to 1-10,000 instead of 1-100. The results seemed even more definitive:

Generating 10000 arrays of data...
Test data generated.
Testing BinarySerializer...
BinaryFormatter: Serializing took 285.8356ms.
BinaryFormatter: Deserializing took 206.0906ms.

Testing ProtoBuf serializer...
ProtoBuf: Serializing took 10693.3848ms.
ProtoBuf: Deserializing took 5988.5993ms.

Testing NetSerializer serializer...
NetSerializer: Serializing took 9017.5785ms.
NetSerializer: Deserializing took 5978.7203ms.
Press any key to end.

My conclusion, therefore, is: there may be cases where ProtoBuf and NetSerializer are well-suited to, but in terms of raw performance for at least relatively simple objects... BinaryFormatter is significantly more performant, by at least an order of magnitude.

YMMV.

Previous answers were good and correct, but in my opinion, an extra names parameter will make it perfect, and it should be the recommended way, especially when the csv has no headers.

Solution

Use usecols and names parameters

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'])

Additional reading

or use header=None to explicitly tells people that the csv has no headers (anyway both lines are identical)

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'], header=None)

So that you can retrieve your data by

# with `names` parameter
df['colA']
df['colB'] 

instead of

# without `names` parameter
df[0]
df[1]

Explain

Based on read_csv, when names are passed explicitly, then header will be behaving like None instead of 0, so one can skip header=None when names exist.

When I had the problem recently it was a cross site issue where our dev server hosts our analytics software as well as the application. In the other environments the chrome console would show this error and the javascript file (tracker) on the dev server as the source. This was causing issues for QA personnel who were trying to view the analytics data for their environment (nothing was being captured because of this issue).

The solution to fix this in-house was to add the SSL certificate the DEV site was using to the Trusted People store on the QA people's machine.

If this was a problem in production I would most likely move the javascript into the actual web apps.

json.loads() takes a JSON encoded string, not a filename. You want to use json.load() (no s) instead and pass in an open file object:

with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
    data = json.load(jsonfile)

The open() command produces a file object that json.load() can then read from, to produce the decoded Python object for you. The with statement ensures that the file is closed again when done.

The alternative is to read the data yourself and then pass it into json.loads().

For those not using arrow functions but something simpler ... I encountered this when adding parentheses after my signOut function ...

replace this <a onClick={props.signOut()}>Log Out</a>

with this <a onClick={props.signOut}>Log Out</a> ... !

1) Upgrade using windows update or using "media creation tool" http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install

• if you are using "media creation tool" select "Upgrade this PC now"

When Windows 10 installed check that it is activated.

2) Now as you have activated Windows 10 using "media creation tool" http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install select second option "Create installation media for another PC" here you can select Windows version and its language. Make sure that Windows version is also "Single Language"

3) Boot from you device, USB in my case and install clean Windows in English or any other language you selected.

All the code is client side, I hope you fine this helpful:

First thing there are 3 functions we will use:

    function setCookie(c_name, value, exdays) {
            var exdate = new Date();
            exdate.setDate(exdate.getDate() + exdays);
            var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
            document.cookie = c_name + "=" + c_value;
        }

    function getCookie(c_name) {
        var i, x, y, ARRcookies = document.cookie.split(";");
        for (i = 0; i < ARRcookies.length; i++) {
            x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
            y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
            x = x.replace(/^\s+|\s+$/g, "");
            if (x == c_name) {
                return unescape(y);
            }
        }
    }

    function DeleteCookie(name) {
            document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
        }

Now we will start with the page load:

$(window).load(function () {
 //if IsRefresh cookie exists
 var IsRefresh = getCookie("IsRefresh");
 if (IsRefresh != null && IsRefresh != "") {
    //cookie exists then you refreshed this page(F5, reload button or right click and reload)
    //SOME CODE
    DeleteCookie("IsRefresh");
 }
 else {
    //cookie doesnt exists then you landed on this page
    //SOME CODE
    setCookie("IsRefresh", "true", 1);
 }
})

Put 0 as default in SQL or add 0 into your area of table

Could do it with :contains() selector as well:

$('#toptitle:contains("Profil")').text("New word");

example: http://jsfiddle.net/niklasvh/xPRzr/

You need to use find instead of grep in this case.

You can also use find in combination with grep or egrep:

$ find | grep "f[[:alnum:]]\.frm"

From Docker documentation:

docker export does not export the contents of volumes associated with the container. If a volume is mounted on top of an existing directory in the container, docker export will export the contents of the underlying directory, not the contents of the volume. Refer to Backup, restore, or migrate data volumes in the user guide for examples on exporting data in a volume.

Import the file into Excel by first opening excel, then going to DATA, import from TXT File, choose the csv extension which will preserve 0 prefixed values, and save that column as TEXT because excel will drop the leading 0 otherwise (DO NOT double click to open with Excel if you have numeric data in a field starting with a 0 [zero]). Then just save out as a Tab Delimited Text file. When you are importing into excel you get an option to save as GENERAL, TEXT, etc.. choose TEXT so that quotes in the middle of a string in a field like YourCompany,LLC are preserved also...

BULK INSERT dbo.YourTableName
FROM 'C:\Users\Steve\Downloads\yourfiletoIMPORT.txt'

)

I wish I could use the FORMAT and Fieldquote functionality but that does not appear to be supported in my version of SSMS

I was trying to connect to mysql from the python code that was executed using spark-submit.

I was using HDP sandbox that was using Ambari. Tried lot of options such as --jars, --driver-class-path, etc, but none worked.

Solution

Copy the jar in /usr/local/miniconda/lib/python2.7/site-packages/pyspark/jars/

As of now I'm not sure if it's a solution or a quick hack, but since I'm working on POC so it kind of works for me.

You could unregister the control with

regsvr32 /u badboy.ocx

at the command line. Though i would suggest testing these things in a vmware.

Most important

Keep in mind that relative URLs are resolved from the URL of your stylesheet.

So it will work if folder images is inside the stylesheets folder.

From you description you would need to change it to either

url("../images/plaid.jpg")

or

url("/images/plaid.jpg") 

Additional 1

Also you cannot have no selector..

CSS is applied through selectors..

Additional 2

You should use either the shorthand background to pass multiple values like this

background: url("../images/plaid.jpg") no-repeat;

or the verbose syntax of specifying each property on its own

background-image: url("../images/plaid.jpg");
background-repeat:no-repeat;

Java doesn't use includes the way C does. Instead java uses a concept called the classpath, a list of resources containing java classes. The JVM can access any class on the classpath by name so if you can extend classes and refer to types simply by declaring them. The closes thing to an include statement java has is 'import'. Since classes are broken up into namespaces like foo.bar.Baz, if you're in the qux package and you want to use the Baz class without having to use its full name of foo.bar.Baz, then you need to use an import statement at the beginning of your java file like so: import foo.bar.Baz

If the page under the overlayer can be "fixed" at the top, when you open the overlay you can set

body { position: fixed; overflow-y:scroll }

you should still see the right scrollbar but the content is not scrollable. When you close the overlay just revert these properties with

body { position: static; overflow-y:auto }

I just proposed this way only because you wouldn't need to change any scroll event

Update

You could also do a slight improvement: if you get the document.documentElement.scrollTop property via javascript just before the layer opening, you could dynamically assign that value as top property of the body element: with this approach the page will stand in its place, no matter if you're on top or if you have already scrolled.

Css

.noscroll { position: fixed; overflow-y:scroll }

JS

$('body').css('top', -(document.documentElement.scrollTop) + 'px')
         .addClass('noscroll');

There is no bidirectional map in the Java Standard API. Either you can maintain two maps yourself or use the BidiMap from Apache Collections.

If you want to store your output into your desktop, follow the below command using post command in git bash.It worked for me.

curl https://localhost:8080 --request POST --header "Content-Type: application/json" -o "C:\Desktop\test.txt"

Polling like this is definitely the least preferred solution.

I assume that you have another thread that will do something to make the condition true. There are several ways to synchronize threads. The easiest one in your case would be a notification via an Object:

Main thread:

synchronized(syncObject) {
    try {
        // Calling wait() will block this thread until another thread
        // calls notify() on the object.
        syncObject.wait();
    } catch (InterruptedException e) {
        // Happens if someone interrupts your thread.
    }
}

Other thread:

// Do something
// If the condition is true, do the following:
synchronized(syncObject) {
    syncObject.notify();
}

syncObject itself can be a simple Object.

There are many other ways of inter-thread communication, but which one to use depends on what precisely you're doing.

If the time is 11:03, then the accepted answer will print 11:3.

You could zero-pad the minutes:

"Created at {:d}:{:02d}".format(tdate.hour, tdate.minute)

Or go another way and use tdate.time() and only take the hour/minute part:

str(tdate.time())[0:5]

Multiple statements are to be separated by a new line:

You might be able to make use of sql.js.

sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. no C bindings or node-gyp compilation here.

<script src='js/sql.js'></script>
<script>
    //Create the database
    var db = new SQL.Database();
    // Run a query without reading the results
    db.run("CREATE TABLE test (col1, col2);");
    // Insert two rows: (1,111) and (2,222)
    db.run("INSERT INTO test VALUES (?,?), (?,?)", [1,111,2,222]);

    // Prepare a statement
    var stmt = db.prepare("SELECT * FROM test WHERE col1 BETWEEN $start AND $end");
    stmt.getAsObject({$start:1, $end:1}); // {col1:1, col2:111}

sql.js is a single JavaScript file and is about 1.5MiB in size currently. While this could be a problem in a web-page, the size is probably acceptable for an extension.

If you have a hash structure like this:

Parameters: {"link"=>{"title"=>"Something", "time_span"=>[{"start"=>"2017-05-06T16:00:00.000Z", "end"=>"2017-05-06T17:00:00.000Z"}]}}

Then this is how I got it to work:

params.require(:link).permit(:title, time_span: [[:start, :end]])

git pull origin master will pull changes from the origin remote, master branch and merge them to the local checked-out branch.

git pull origin/master will pull changes from the locally stored branch origin/master and merge that to the local checked-out branch. The origin/master branch is essentially a "cached copy" of what was last pulled from origin, which is why it's called a remote branch in git parlance. This might be somewhat confusing.

You can see what branches are available with git branch and git branch -r to see the "remote branches".

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

For me I had a

create table mytable ( 
    dadada 
)

and forgot the semicolon at the end.

So looks like this error can occur after simple syntax errors. Just like it says.. I guess you can never read the helpful compiler comments closely enough.

I was getting an error

"ImportError: Install xlrd >= 1.0.0 for Excel support"

on Pycharm for below code

import pandas as pd
df2 = pd.read_excel("data.xlsx")
print(df2.head(3))
print(df2.tail(3))

Solution : pip install xlrd

It resolved error after using this. Also no need to use "import xlrd"

Just call it

Make sure it will be found (path).

Another method would be to use:

$(document).bind("touchmove",function(event){
  event.preventDefault();
});

But it may prevent some of the jquery mobile functionality from working properly.

Having: It applies filter conditions to each group of rows. Where: It applies a filter of individual rows.

You can use BOOL, BOOLEAN data type for storing boolean values.

These types are synonyms for TINYINT(1)

However, the BIT(1) data type makes more sense to store a boolean value (either true[1] or false[0]) but TINYINT(1) is easier to work with when you're outputting the data, querying and so on and to achieve interoperability between MySQL and other databases. You can also check this answer or thread.

MySQL also converts BOOL, BOOLEAN data types to TINYINT(1).

Further, read documentation

If you are using eclipse, you should modify the context.xml, from the server project created in your eclipse package explorer. When using tomcat in eclipse it is the only one valid, the others are ignored or overwriten

$xml = <<<XML
<root>
<elem attrib="value" />
</root>
XML;

$sxml = simplexml_load_string($xml);
$attrs = $sxml->elem->attributes();
echo $attrs["attrib"]; //or just $sxml->elem["attrib"]

Use SimpleXMLElement::attributes.

Truth is, the SimpleXMLElement get_properties handler lies big time. There's no property named "@attributes", so you can't do $sxml->elem->{"@attributes"}["attrib"].

I assume you are wanting one of the two methods:

Keep Duplicate elements

It is very easy, just concatenate like string:

def concat_list(l1,l2):
    l3 = l1+l2
    return l3

Next if you want to eliminate duplicate elements

def concat_list(l1,l2):
   l3 = []
   for i in [l1,l2]:
     for j in i:   
       if j not in l3:   
         #Check if element exists in final list, if no then add element to list
         l3.append(j)
   return l3

If you need the list of users that are in a group, you can do this instead:

from django.contrib.auth.models import Group
users_in_group = Group.objects.get(name="group name").user_set.all()

and then check

 if user in users_in_group:
     # do something

to check if the user is in the group.

Many neural network training algorithms involve making multiple presentations of the entire data set to the neural network. Often, a single presentation of the entire data set is referred to as an "epoch". In contrast, some algorithms present data to the neural network a single case at a time.

"Iteration" is a much more general term, but since you asked about it together with "epoch", I assume that your source is referring to the presentation of a single case to a neural network.

If you want to use Netbeans to define tables read this https://codezone4.wordpress.com/2012/06/19/java-database-application-using-javadb-part-1/ Simply define column as integer and create database, then grab structure to a temporary file, then delete table. Right clik to tables folder and select recreate table, select saved file and edit script for auto increment.

It seems like GSON supports this, although I don't know if you want to switch from the library you are using.

use blank? http://api.rubyonrails.org/classes/Object.html#method-i-blank-3F

unless params[:one].blank? && params[:two].blank?

will return true if its empty or nil

also... that will not work if you are testing boolean values.. since

>> false.blank?
=> true

in that case you could use

unless params[:one].to_s.blank? && params[:two].to_s.blank?

Yes, as you can see the support-package instantiates the fragments too (when they get destroyed and re-opened). Your Fragment subclasses need a public empty constructor as this is what's being called by the framework.

Multiple parameters can be given like below,

    @RequestMapping(value = "/mno/{objectKey}", method = RequestMethod.GET, produces = "application/json")
    public List<String> getBook(HttpServletRequest httpServletRequest, @PathVariable(name = "objectKey") String objectKey
      , @RequestParam(value = "id", defaultValue = "false")String id,@RequestParam(value = "name", defaultValue = "false") String name) throws Exception {
               //logic
}

Use .closest() to traverse up the DOM tree up to the specified selector.

var classes = $(this).parent().closest('div').attr('class').split(' '); // this gets the parent classes.

For windows, If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'port';


mysql> SHOW VARIABLES WHERE Variable_name = 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)

It will give you the port number on which MySQL is running.

If you want to remove or unset all $_SESSION 's then try this

session_destroy();

If you want to remove specific $_SESSION['name'] then try this

session_unset('name');

Yes, underscores may be used anywhere in an identifier. I believe the rules are: any of a-z, A-Z, _ in the first character and those +0-9 for the following characters.

Underscore prefixes are common in C code -- a single underscore means "private", and double underscores are usually reserved for use by the compiler.

In your script, this part:

document.getElementById('Noite')

must be returning null and you are also attempting to set the display property to an invalid value. There are a couple of possible reasons for this first part to be null.

1. You are running the script too early before the document has been loaded and thus the Noite item can't be found.

2. There is no Noite item in your HTML.

I should point out that your use of document.write() in this case code probably signifies a problem. If the document has already loaded, then a new document.write() will clear the old content and start a new fresh document so no Noite item would be found.

If your document has not yet been loaded and thus you're doing document.write() inline to add HTML inline to the current document, then your document has not yet been fully loaded so that's probably why it can't find the Noite item.

The solution is probably to put this part of your script at the very end of your document so everything before it has already been loaded. So move this to the end of your body:

document.getElementById('Noite').style.display='block';

And, make sure that there are no document.write() statements in javascript after the document has been loaded (because they will clear the previous document and start a new one).

In addition, setting the display property to "display" doesn't make sense to me. The valid options for that are "block", "inline", "none", "table", etc... I'm not aware of any option named "display" for that style property. See here for valid options for teh display property.

You can see the fixed code work here in this demo: http://jsfiddle.net/jfriend00/yVJY4/. That jsFiddle is configured to have the javascript placed at the end of the document body so it runs after the document has been loaded.

P.S. I should point out that your lack of braces for your if statements and your inclusion of multiple statements on the same line makes your code very misleading and unclear.

I'm having a really hard time figuring out what you're asking, but here's a cleaned up version of your code that works which you can also see working here: http://jsfiddle.net/jfriend00/QCxwr/. Here's a list of the changes I made:

1. The script is located in the body, but after the content that it is referencing.
2. I've added var declarations to your variables (a good habit to always use).
3. The if statement was changed into an if/else which is a lot more efficient and more self-documenting as to what you're doing.
4. I've added braces for every if statement so it absolutely clear which statements are part of the if/else and which are not.
5. I've properly closed the </dd> tag you were inserting.
6. I've changed style.display = ''; to style.display = 'block';.
7. I've added semicolons at the end of every statement (another good habit to follow).

The code:

<div id="Night" style="display: none;">
    <img src="Img/night.png" style="position: fixed; top: 0px; left: 5%; height: auto; width: 100%; z-index: -2147483640;">
    <img src="Img/moon.gif" style="position: fixed; top: 0px; left: 5%; height: 100%; width: auto; z-index: -2147483639;">
</div>    
<script>
document.write("<dl><dd>");
var day = new Date();
var hr = day.getHours();
if (hr == 0) {
    document.write("Meia-noite!<br>Já é amanhã!");
} else if (hr <=5 ) {
    document.write("&nbsp;&nbsp;Você não<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;devia<br>&nbsp;&nbsp;&nbsp;&nbsp;estar<br>dormindo?");
} else if (hr <= 11) {         
    document.write("Bom dia!");
} else if (hr == 12) {
    document.write("&nbsp;&nbsp;&nbsp;&nbsp;Vamos<br>&nbsp;almoçar?");
} else if (hr <= 17) {
    document.write("Boa Tarde");
} else if (hr <= 19) {
    document.write("&nbsp;Bom final<br>&nbsp;de tarde!");
} else if (hr == 20) {
    document.write("&nbsp;Boa Noite"); 
    document.getElementById('Noite').style.display='block';
} else if (hr == 21) {
    document.write("&nbsp;Boa Noite"); 
    document.getElementById('Noite').style.display='none';
} else if (hr == 22) {
    document.write("&nbsp;Boa Noite");
} else if (hr == 23) {
    document.write("Ó Meu! Já é quase meia-noite!");
}
document.write("</dl></dd>");
</script>

Any solution work only if List a list(of string)

If you have a generic list of your own Objects like list(of car) where car has n properties, you must loop the PropertiesInfo of each car object.

Look at: http://www.csharptocsharp.com/generate-csv-from-generic-list

You can also use 2 methods from java.time.YearMonth( Since Java 8 ):

import java.time.YearMonth;
...
int year = YearMonth.now().getYear();
int month = YearMonth.now().getMonthValue();

You are using Python 2 methodology instead of Python 3.

Change:

outfile=open('./immates.csv','wb')

To:

outfile=open('./immates.csv','w')

and you will get a file with the following output:

SNo,States,Dist,Population
1,Andhra Pradesh,13,49378776
2,Arunachal Pradesh,16,1382611
3,Assam,27,31169272
4,Bihar,38,103804637
5,Chhattisgarh,19,25540196
6,Goa,2,1457723
7,Gujarat,26,60383628
.....

In Python 3 csv takes the input in text mode, whereas in Python 2 it took it in binary mode.

Here is the code I ran:

url='http://www.mapsofindia.com/districts-india/'

list_of_rows=[]
for row in table.findAll('tr')[1:]:
    list_of_cells=[]
    for cell in row.findAll('td'):
        list_of_cells.append(cell.text)
    list_of_rows.append(list_of_cells)
outfile = open('./immates.csv','w')
writer=csv.writer(outfile)
writer.writerow(['SNo', 'States', 'Dist', 'Population'])
writer.writerows(list_of_rows)

DateFormat df = new SimpleDateFormat("HH:mm:ss");
String formatted = df.format(aDateObject);

Here is a possible solution:

def download_list_s3_folder(my_bucket,my_folder):
    import boto3
    s3 = boto3.client('s3')
    response = s3.list_objects_v2(
        Bucket=my_bucket,
        Prefix=my_folder,
        MaxKeys=1000)
    return [item["Key"] for item in response['Contents']]

Couple of problems:

The while should be a for You are not returning a value but you have declared a return type of double

double average = sum / data.length;;

sum and data.length are both ints so the division will return an int - check your types

double semi-colon, probably won't break it, just looks odd.

I agree with pez and some here.

It seems obvious to me that "new" is self descriptive object creation, where the YUI pattern Greg Dean describes is completely obscured.

The possibility someone could write var bar = foo; or var bar = baz(); where baz isn't an object creating method seems far more dangerous.

Define a class

public class Language
{
     public string Name { get; set; }
     public string Value { get; set; }
}

then...

//Build a list
var dataSource = new List<Language>();
dataSource.Add(new Language() { Name = "blah", Value = "blah" });
dataSource.Add(new Language() { Name = "blah", Value = "blah" });
dataSource.Add(new Language() { Name = "blah", Value = "blah" });

//Setup data binding
this.comboBox1.DataSource = dataSource;
this.comboBox1.DisplayMember = "Name";
this.comboBox1.ValueMember = "Value";

// make it readonly
this.comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

And this gives the total:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

If you need more detail, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)

For example like this:

var value = $("#a").find("#b").val()

I think it suffices to hand the data over directly:

$("#inputhidden").select2("data", data, true);

Note that the second parameter seems to indicate that a refresh is desired.

Thanks to @Bergi for help with this.

If that doesn't automatically update you could either try calling it's updateResults method directly.

$("#inputhidden").select2("updateResults");

Or trigger it indirectly by sending a trigger to the "input.select2-input" like so:

var search = $("#inputhidden input.select2-input");
search.trigger("input");

I've created a custom PagerAdapters library to change items in PagerAdapters dynamically.

You can change items dynamically like following by using this library.

@Override
protected void onCreate(Bundle savedInstanceState) {
        /** ... **/
    adapter = new MyStatePagerAdapter(getSupportFragmentManager()
                            , new String[]{"1", "2", "3"});
    ((ViewPager)findViewById(R.id.view_pager)).setAdapter(adapter);
     adapter.add("4");
     adapter.remove(0);
}

class MyPagerAdapter extends ArrayViewPagerAdapter<String> {

    public MyPagerAdapter(String[] data) {
        super(data);
    }

    @Override
    public View getView(LayoutInflater inflater, ViewGroup container, String item, int position) {
        View v = inflater.inflate(R.layout.item_page, container, false);
        ((TextView) v.findViewById(R.id.item_txt)).setText(item);
        return v;
    }
}

Thils library also support pages created by Fragments.

Open a command prompt:

 Version:  java -version
 Location: where java (in Windows)
           which java (in Unix, Linux, and Mac)

To set Java home in Windows:

Right click on My computer → Properties → Advanced system settings → Environment Variable → System Variable → New. Give the name as JAVA_HOME and the value as (e.g.) c:\programfiles\jdk

Select Path and click Edit, and keep it in the beginning as: %JAVA_HOME%\bin;...remaining settings goes here

Here are simple regex to understand (verified, and no preceding 0)

Between 0 to 100 (Try it here):

^(0|[1-9][0-9]?|100)$

Between 1 to 100 (Try it here):

^([1-9][0-9]?|100)$

In the app/web.config file set the following configuration:

<configuration>
  <appSettings>
    <add key="NameForTheKey" value="ValueForThisKey" />
    ... 
    ...    
  </appSettings>
...
...
</configuration>

then you can access this in your code by putting in this line:

string myVar = System.Configuration.ConfigurationManager.AppSettings["NameForTheKey"];

*Note that this work fine for .net4.5.x and .net4.6.x; but do not work for .net core. Best regards: Rafael

I had this info message "No Spring WebApplicationInitializer types detected on classpath" while deploying a WAR with spring integration beans in WebLogic server. Actually, I could observe that the servlet URL returned 404 Not Found and beside that info message with a negative tone "No Spring ...etc" in Server logs, nothing else was seemingly in error in my spring config; no build or deployment errors, no complaints. Indeed, I suspected that the beans.xml (spring context XML) was actually not picked up at all and that was bound to the very specific organizing of artefacts in Oracle's jDeveloper. The solution is to play carefully with the 'contributors' and 'filters' for the WEB-INF/classes category when you edit your deployment profile under the 'deployment' topic in project properties.

Precisely, I would advise to name your spring context by the jDeveloper default "beans.xml" and place it side by side to the WEB-INF subdirectory itself (under your web Apllication source path, e.g. like <...your project path>/public_html/). Then in the WEB-INF/classes category (when editing the deployment profile) your can check the Project HTML root directory in the 'contributor' list, and then select the beans.xml in filters, and then ensure your web.xml features a context-param value like classpath:beans.xml.

Once that was fixed, I was able to progress and after some more bean config changes and implementations, the message "No Spring WebApplicationInitializer types detected on classpath" came back! Actually, I did not notice when and why exactly it came back. This second time, I added a

public class HttpGatewayInit implements WebApplicationInitializer { ... }

which implements empty inherited methods, and the whole application works fine!

...If you feel that java EE development has been getting a bit too crazy with cascades of XML configuration files (some edited manually, others through wizards) intepreted by cascades of variant initializers, let me insist that I fully share your point.

If you run docker run <NAME> it will spawn a new image, which most likely isn't what you want.

If you want to change a current image do the following:

docker ps -a

Take the id of your target container and go to:

cd /var/lib/docker/containers/<conainerID><and then some:)>

Stop the container:

docker stop <NAME>

Change the files

vi config.v2.json

"Config": {
    ....
    "ExposedPorts": {
        "80/tcp": {},
        "8888/tcp": {}
    },
    ....
},
"NetworkSettings": {
....
"Ports": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],

And change file

vi hostconfig.json

"PortBindings": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],
     "8888/tcp": [
         {
             "HostIp": "",
             "HostPort": "8888"
         } 
     ]
 }

Restart your docker and it should work.

For an uglier version of unshift use splice:

TheArray.splice(0, 0, TheNewObject);

Another approach is to filter using LINQ before the loop executes:

foreach ( int number in numbers.Where(n => n >= 0) )
{
    // process number
}

If everything you want to drop is owned by the same user, then you can use:

drop owned by the_user;

This will drop everything that the user owns.

That includes materialized views, views, sequences, triggers, schemas, functions, types, aggregates, operators, domains and so on (so, really: everything) that the_user owns (=created).

You have to replace the_user with the actual username, currently there is no option to drop everything for "the current user". The upcoming 9.5 version will have the option drop owned by current_user.

You need to use a long literal:

But I would expect that function to run out of memory (or time) ...

Anyone who says that JDO is dead is an astroturfing FUD monger and they know it.

JDO is alive and well. The specification is still more powerful, mature and advanced than the much younger and constrained JPA.

If you want to limit yourself to only what's available in the JPA standard you can write to JPA and use DataNucleus as a high performance, more transparent persistence implementation than the other implementations of JPA. Of course DataNucleus also implements the JDO standard if you want the flexibility and efficiency of modeling that JDO brings.

The best way I found, aside of using a dedicated commit GUI, is to use git difftool -d - This opens your diff tool in directory comparison mode, comparing HEAD with current dirty folder.

You were close. This will work:

.image { position: relative; border: 1px solid black; width: 200px; height: 200px; }
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; right:0; bottom:0; display: none; background-color: rgba(0,0,0,0.5); }
.image:hover .overlay { display: block; }

You needed to put the :hover on image, and make the .overlay cover the whole image by adding right:0; and bottom:0.

I guess that this code should answer your question:

use strict;
use warnings;

my @keys = qw/one two three two/;
my %hash;
for my $key (@keys)
{
    $hash{$key}++;
}

for my $key (keys %hash)
{
   print "$key: ", $hash{$key}, "\n";
}

Output:

three: 1
one: 1
two: 2

The iteration can be simplified to:

$hash{$_}++ for (@keys);

(See $_ in perlvar.) And you can even write something like this:

$hash{$_}++ or print "Found new value: $_.\n" for (@keys);

Which reports each key the first time it’s found.

  is a HTML entity. When doing .text(), all HTML entities are decoded to their character values.

Instead of comparing using the entity, compare using the actual raw character:

var x = td.text();
if (x == '\xa0') { // Non-breakable space is char 0xa0 (160 dec)
  x = '';
}

Or you can also create the character from the character code manually it in its Javascript escaped form:

var x = td.text();
if (x == String.fromCharCode(160)) { // Non-breakable space is char 160
  x = '';
}

More information about String.fromCharCode is available here:

Add android:screenOrientation="portrait" to the activity in the AndroidManifest.xml. For example:

<activity android:name=".SomeActivity"
    android:label="@string/app_name"
    android:screenOrientation="portrait" />

EDIT: Since this has become a super-popular answer, I feel very guilty as forcing portrait is rarely the right solution to the problems it's frequently applied to.
The major caveats with forced portrait:

• This does not absolve you of having to think about activity lifecycle events or properly saving/restoring state. There are plenty of things besides app rotation that can trigger an activity destruction/recreation, including unavoidable things like multitasking. There are no shortcuts; learn to use bundles and retainInstance fragments.
• Keep in mind that unlike the fairly uniform iPhone experience, there are some devices where portrait is not the clearly popular orientation. When users are on devices with hardware keyboards or game pads a la the Nvidia Shield, on Chromebooks, on foldables, or on Samsung DeX, forcing portrait can make your app experience either limiting or a giant usability hassle. If your app doesn't have a strong UX argument that would lead to a negative experience for supporting other orientations, you should probably not force landscape. I'm talking about things like "this is a cash register app for one specific model of tablet always used in a fixed hardware dock."

So most apps should just let the phone sensors, software, and physical configuration make their own decision about how the user wants to interact with your app. A few cases you may still want to think about, though, if you're not happy with the default behavior of sensor orientation in your use case:

• If your main concern is accidental orientation changes mid-activity that you think the device's sensors and software won't cope with well (for example, in a tilt-based game) consider supporting landscape and portrait, but using nosensor for the orientation. This forces landscape on most tablets and portrait on most phones, but I still wouldn't recommend this for most "normal" apps (some users just like to type in the landscape softkeyboard on their phones, and many tablet users read in portrait - and you should let them).
• If you still need to force portrait for some reason, sensorPortrait may be better than portrait for Android 2.3+; this allows for upside-down portrait, which is quite common in tablet usage.

          Delete_Directory( $file );      
      }

I try like this with function then calling if needed a this function. Has been worked for me.

function modal_fix() {
var a = $(".modal"),
    b = $("body");
a.on("shown.bs.modal", function () {
    b.hasClass("modal-open") || b.addClass("modal-open");
});
}

You can use ggplot2 to rotate the x-axis label adding an additional layer

theme(axis.text.x = element_text(angle = 90, hjust = 1))

Test whether something exists at given path using the -e file-test operator.

print "$base_path exists!\n" if -e $base_path;

However, this test is probably broader than you intend. The code above will generate output if a plain file exists at that path, but it will also fire for a directory, a named pipe, a symlink, or a more exotic possibility. See the documentation for details.

Given the extension of .TGZ in your question, it seems that you expect a plain file rather than the alternatives. The -f file-test operator asks whether a path leads to a plain file.

print "$base_path is a plain file!\n" if -f $base_path;

The perlfunc documentation covers the long list of Perl's file-test operators that covers many situations you will encounter in practice.

• -r
  File is readable by effective uid/gid.
• -w
  File is writable by effective uid/gid.
• -x
  File is executable by effective uid/gid.
• -o
  File is owned by effective uid.
• -R
  File is readable by real uid/gid.
• -W
  File is writable by real uid/gid.
• -X
  File is executable by real uid/gid.
• -O
  File is owned by real uid.
• -e
  File exists.
• -z
  File has zero size (is empty).
• -s
  File has nonzero size (returns size in bytes).
• -f
  File is a plain file.
• -d
  File is a directory.
• -l
  File is a symbolic link (false if symlinks aren’t supported by the file system).
• -p
  File is a named pipe (FIFO), or Filehandle is a pipe.
• -S
  File is a socket.
• -b
  File is a block special file.
• -c
  File is a character special file.
• -t
  Filehandle is opened to a tty.
• -u
  File has setuid bit set.
• -g
  File has setgid bit set.
• -k
  File has sticky bit set.
• -T
  File is an ASCII or UTF-8 text file (heuristic guess).
• -B
  File is a “binary” file (opposite of -T).
• -M
  Script start time minus file modification time, in days.
• -A
  Same for access time.
• -C
  Same for inode change time (Unix, may differ for other platforms)

Some ideas:

• Use git mergetool to split the merge files into original and new parts. Hopefully one of those is the file with your non-stash changes in it.

• Apply the diff of the stash in reverse, to undo just those changes. You'll probably have to manually split out the files with the merge conflicts (which hopefully the above trick will work for).

I didn't test either of these, so I don't know for sure of they will work.

Using function Find is cleaner way.

MyClass item = MyList.Find(item => item.name == "foo");
if (item != null) // check item isn't null
{
 ....
}

You can use command line tool to build the release version. Next to your project folder, i.e.

$ ls
...
Foo.xcodeproj
...

Type the following build command:

$ xcodebuild -configuration Release

Use new Date(dateString) if your string is compatible with Date.parse(). If your format is incompatible (I think it is), you have to parse the string yourself (should be easy with regular expressions) and create a new Date object with explicit values for year, month, date, hour, minute and second.

Here is an easy one:

$myVar > "c:\myfilepath\myfilename.myextension"

You can also try:

Get-content "c:\someOtherPath\someOtherFile.myextension" > "c:\myfilepath\myfilename.myextension"

IMHO better than the accepted answer is to use the following:

git config --local status.showUntrackedFiles no

The accepted answer does not work for when new files are added that are not in .gitignore

Let's Encrypt is a free, automated, and open certificate authority made by the Internet Security Research Group (ISRG). It is sponsored by well-known organisations such as Mozilla, Cisco or Google Chrome. All modern browsers are compatible and trust Let's Encrypt.

All certificates are free (even wildcard certificates)! For security reasons, the certificates expire pretty fast (after 90 days). For this reason, it is recommended to install an ACME client, which will handle automatic certificate renewal.

There are many clients you can use to install a Let's Encrypt certificate:

Let’s Encrypt uses the ACME protocol to verify that you control a given domain name and to issue you a certificate. To get a Let’s Encrypt certificate, you’ll need to choose a piece of ACME client software to use. - https://letsencrypt.org/docs/client-options/

How can a simple task be made complicated. My solution is:

public String removeLastChar(String s) {
    return s[0..-1]
}

or

public String removeLastChar(String s) {
    if (s.length() > 0) {
        return s[0..-1]
    }
    return s
}

Just remove activation section, I don't know why -Pdev1 doesn't override default false activation. But if you omit this:

<activation> <activeByDefault>false</activeByDefault> </activation>

then your profile will be activated only after explicit declaration as -Pdev1

Modify the DataNode class so that it implements Comparable interface.

public int compareTo(DataNode o)
{
     return(degree - o.degree);
}

then just use

Collections.sort(nodeList);

Use of pseudo-element as suggested by Terry has one PRO and one CON:

1. PRO - great cross-browser compatibility because pseudo-element are supported also on older IE.
2. CON - it requires to create an extra (even if generated) element, that infact is defined pseudo-element.

Anyway is a great solution.

OTHER SOLUTIONS:

If you can accept compatibility since IE9 (IE8 does not have support for this), you can achieve desired result in other two possible ways:

1. using outline property combined with border and a single inset box-shadow
2. using two box-shadow combined with border.

Here a jsFiddle with Terry's modified code that shows, side by side, these other possible solutions. Main specific properties for each one are the following (others are shared in .double-border class):

.left
{
  outline: 4px solid #fff;
  box-shadow:inset 0 0 0 4px #fff;
}

.right
{
  box-shadow:0 0 0 4px #fff, inset 0 0 0 4px #fff;
}

LESS code:

You asked for possible advantages about using a pre-processor like LESS. I this specific case, utility is not so great, but anyway you could optimize something, declaring colors and border/ouline/shadow with @variable.

Here an example of my CSS code, declared in LESS (changing colors and border-width becomes very quick):

@double-border-size:4px;
@inset-border-color:#fff;
@content-color:#ccc;

.double-border 
{
  background-color: @content-color;
  border: @double-border-size solid @content-color;
  padding: 2em;
  width: 16em;
  height: 16em;
  float:left;
  margin-right:20px;
  text-align:center;
}

.left
{
  outline: @double-border-size solid @inset-border-color;
  box-shadow:inset 0 0 0 @double-border-size @inset-border-color;
}

.right
{
  box-shadow:0 0 0 @double-border-size @inset-border-color, inset 0 0 0 @double-border-size @inset-border-color;
}

It will work for any object. Even if you don't know the size:

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

you should not use Nested List in List.

List<List<T>> 

is not legal, even if T were a defined type.

Here's the method I use (for similar things, not just title):

<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head>
<title><!--TITLE--></title>
</head>

<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer

// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>

PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';", that string will get sent the browser and is emptied from memory.

What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."

So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.

ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.

Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title> with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.

It effectively holds onto output so you can manipulate it before sending it to the browser.

Hopefully my comments are clear enough. Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)

NOTE: nosid's answer shows how to add to an existing collection using forEachOrdered(). This is a useful and effective technique for mutating existing collections. My answer addresses why you shouldn't use a Collector to mutate an existing collection.

The short answer is no, at least, not in general, you shouldn't use a Collector to modify an existing collection.

The reason is that collectors are designed to support parallelism, even over collections that aren't thread-safe. The way they do this is to have each thread operate independently on its own collection of intermediate results. The way each thread gets its own collection is to call the Collector.supplier() which is required to return a new collection each time.

These collections of intermediate results are then merged, again in a thread-confined fashion, until there is a single result collection. This is the final result of the collect() operation.

A couple answers from Balder and assylias have suggested using Collectors.toCollection() and then passing a supplier that returns an existing list instead of a new list. This violates the requirement on the supplier, which is that it return a new, empty collection each time.

This will work for simple cases, as the examples in their answers demonstrate. However, it will fail, particularly if the stream is run in parallel. (A future version of the library might change in some unforeseen way that will cause it to fail, even in the sequential case.)

Let's take a simple example:

List<String> destList = new ArrayList<>(Arrays.asList("foo"));
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");
newList.parallelStream()
       .collect(Collectors.toCollection(() -> destList));
System.out.println(destList);

When I run this program, I often get an ArrayIndexOutOfBoundsException. This is because multiple threads are operating on ArrayList, a thread-unsafe data structure. OK, let's make it synchronized:

List<String> destList =
    Collections.synchronizedList(new ArrayList<>(Arrays.asList("foo")));

This will no longer fail with an exception. But instead of the expected result:

[foo, 0, 1, 2, 3]

it gives weird results like this:

[foo, 2, 3, foo, 2, 3, 1, 0, foo, 2, 3, foo, 2, 3, 1, 0, foo, 2, 3, foo, 2, 3, 1, 0, foo, 2, 3, foo, 2, 3, 1, 0]

This is the result of the thread-confined accumulation/merging operations I described above. With a parallel stream, each thread calls the supplier to get its own collection for intermediate accumulation. If you pass a supplier that returns the same collection, each thread appends its results to that collection. Since there is no ordering among the threads, results will be appended in some arbitrary order.

Then, when these intermediate collections are merged, this basically merges the list with itself. Lists are merged using List.addAll(), which says that the results are undefined if the source collection is modified during the operation. In this case, ArrayList.addAll() does an array-copy operation, so it ends up duplicating itself, which is sort-of what one would expect, I guess. (Note that other List implementations might have completely different behavior.) Anyway, this explains the weird results and duplicated elements in the destination.

You might say, "I'll just make sure to run my stream sequentially" and go ahead and write code like this

stream.collect(Collectors.toCollection(() -> existingList))

anyway. I'd recommend against doing this. If you control the stream, sure, you can guarantee that it won't run in parallel. I expect that a style of programming will emerge where streams get handed around instead of collections. If somebody hands you a stream and you use this code, it'll fail if the stream happens to be parallel. Worse, somebody might hand you a sequential stream and this code will work fine for a while, pass all tests, etc. Then, some arbitrary amount of time later, code elsewhere in the system might change to use parallel streams which will cause your code to break.

OK, then just make sure to remember to call sequential() on any stream before you use this code:

stream.sequential().collect(Collectors.toCollection(() -> existingList))

Of course, you'll remember to do this every time, right? :-) Let's say you do. Then, the performance team will be wondering why all their carefully crafted parallel implementations aren't providing any speedup. And once again they'll trace it down to your code which is forcing the entire stream to run sequentially.

Don't do it.

In 2020, just do

$.datetimepicker.setLocale('en');

Of course, replace 'en' with the correct language ('sv', 'fr', ...)

In addition to the answer of "dasblinkenlight" I think an example could help. I will only use 8 bits for a better understanding.

x & 1 produces a value that is either 1 or 0, depending on the least significant bit of x: if the last bit is 1, the result of x & 1 is 1; otherwise, it is 0. This is a bitwise AND operation.

This is because 1 will be represented in bits as 00000001. Only the last bit is set to 1. Let's assume x is 185 which will be represented in bits as 10111001. If you apply a bitwise AND operation on x with 1 this will be the result:

00000001
10111001
--------
00000001

The first seven bits of the operation result will be 0 after the operation and will carry no information in this case (see Logical AND operation). Because whatever the first seven bits of the operand x were before, after the operation they will be 0. But the last bit of the operand 1 is 1 and it will reveal if the last bit of operand x was 0 or 1. So in this example the result of the bitwise AND operation will be 1 because our last bit of x is 1. If the last bit would have been 0, then the result would have been also 0, indicating that the last bit of operand x is 0:

00000001
10111000
--------
00000000

x >>= 1 means "set x to itself shifted by one bit to the right". The expression evaluates to the new value of x after the shift

Let's pick the example from above. For x >>= 1 this would be:

10111001
--------
01011100

And for left shift x <<= 1 it would be:

10111001
--------
01110010

Please pay attention to the note of user "dasblinkenlight" in regard to shifts.

Microsoft Visual Studio is funny when your using the installer you MUST checkbox a-lot of options to bypass the .netframework(somewhat) to make more c++ instead of c sharp applications, such as the clr options under dekstop development... in visual studio installer.... difference is c++ win32 console project or a c++ CLR console project. So whats the difference? Well i'm not going to list all of the files CLR includes but since most good c++ kernals are in linux... so CLR allows you to bypass a-lot of the windows .netframework b/c visual studio was really meant for you to make apps in C sharp.

Heres a C++ win32 console project!

#include "stdafx.h"
#include <iostream>
using namespace std;
int main( )
{
cout<<"Hello World"<<endl;
return 0;
}

Now heres a c++ CLR console project!

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
Console::WriteLine("Hello World");
return 0;
}

Both programs do the same thing .... CLR just looks more frameworked class overloading methodology so microsoft can great it's own vast library you should familiarize yourself w/ if so inclined. https://msdn.microsoft.com/en-us/library/2e6a4at9.aspx

You should use live method for elements which are rendered later, like colorbox, hidden fields or iframe

$(".inverter-value").live("change",function() {
     elem = this
    $.ajax({
      url: '/main/invertor_attribute/',
      type: 'POST',
      aysnc: false,
      data: {id: $(this).val() },
      success: function(data){
       // code
      },
      dataType: 'html'
    });
  });

The problem is extra 13 byte which server.py receives at the start. To resolve that write "l = c.recv(1024)" twice before the while loop as below.

print "Receiving..."
l = c.recv(1024) #this receives 13 bytes which is corrupting the data
l = c.recv(1024) # Now actual data starts receiving
while (l):

This resolves the issue, tried with different format and sizes of files. If anyone knows what this starting 13 bytes refers to, please reply.

A quick grep of the libstd++ code base revealed the following two usages of __gx_personality_v0:

In libsupc++/unwind-cxx.h

// GNU C++ personality routine, Version 0.                                      
extern "C" _Unwind_Reason_Code __gxx_personality_v0
     (int, _Unwind_Action, _Unwind_Exception_Class,
      struct _Unwind_Exception *, struct _Unwind_Context *);

In libsupc++/eh_personality.cc

#define PERSONALITY_FUNCTION    __gxx_personality_v0
extern "C" _Unwind_Reason_Code
PERSONALITY_FUNCTION (int version,
                      _Unwind_Action actions,
                      _Unwind_Exception_Class exception_class,
                      struct _Unwind_Exception *ue_header,
                      struct _Unwind_Context *context)
{
  // ... code to handle exceptions and stuff ...
}

(Note: it's actually a little more complicated than that; there's some conditional compilation that can change some details).

So, as long as your code isn't actually using exception handling, defining the symbol as void* won't affect anything, but as soon as it does, you're going to crash - __gxx_personality_v0 is a function, not some global object, so trying to call the function is going to jump to address 0 and cause a segfault.

SilverSkin and Anders are both correct. You can use parentheses to execute multiple commands. However, you have to make sure that the commands themselves (and their parameters) do not contain parentheses. cmd greedily searches for the first closing parenthesis, instead of handling nested sets of parentheses gracefully. This may cause the rest of the command line to fail to parse, or it may cause some of the parentheses to get passed to the commands (e.g. DEL myfile.txt)).

A workaround for this is to split the body of the loop into a separate function. Note that you probably need to jump around the function body to avoid "falling through" into it.

FOR /r %%X IN (*.txt) DO CALL :loopbody %%X
REM Don't "fall through" to :loopbody.
GOTO :EOF

:loopbody
ECHO %1
DEL %1
GOTO :EOF

In the answer from @mariubog (https://stackoverflow.com/a/27882337/1279002) I was using password grant types too as in the example but needed to set the client authentication scheme to form. Scopes were not supported by the endpoint for password and there was no need to set the grant type as the ResourceOwnerPasswordResourceDetails object sets this itself in the constructor.

...

public ResourceOwnerPasswordResourceDetails() {
    setGrantType("password");
}

...

The key thing for me was the client_id and client_secret were not being added to the form object to post in the body if resource.setClientAuthenticationScheme(AuthenticationScheme.form); was not set.

See the switch in: org.springframework.security.oauth2.client.token.auth.DefaultClientAuthenticationHandler.authenticateTokenRequest()

Finally, when connecting to Salesforce endpoint the password token needed to be appended to the password.

@EnableOAuth2Client
@Configuration
class MyConfig {

@Value("${security.oauth2.client.access-token-uri}")
private String tokenUrl;

@Value("${security.oauth2.client.client-id}")
private String clientId;

@Value("${security.oauth2.client.client-secret}")
private String clientSecret;

@Value("${security.oauth2.client.password-token}")
private String passwordToken;

@Value("${security.user.name}")
private String username;

@Value("${security.user.password}")
private String password;


@Bean
protected OAuth2ProtectedResourceDetails resource() {

    ResourceOwnerPasswordResourceDetails resource = new ResourceOwnerPasswordResourceDetails();

    resource.setAccessTokenUri(tokenUrl);
    resource.setClientId(clientId);
    resource.setClientSecret(clientSecret);
    resource.setClientAuthenticationScheme(AuthenticationScheme.form);
    resource.setUsername(username);
    resource.setPassword(password + passwordToken);

    return resource;
}

@Bean
 public OAuth2RestOperations restTemplate() {
    return new OAuth2RestTemplate(resource(), new DefaultOAuth2ClientContext(new DefaultAccessTokenRequest()));
    }
}


@Service
@SuppressWarnings("unchecked")
class MyService {
    @Autowired
    private OAuth2RestOperations restTemplate;

    public MyService() {
        restTemplate.getAccessToken();
    }
}

if you are working on dynamic permissions and any permission like ACCESS_FINE_LOCATION,ACCESS_COARSE_LOCATION giving error "cannot resolve method PERMISSION_NAME" in this case write you code with permission name and then rebuild your project this will regenerate the manifest(Manifest.permission) file.

As an alternative answer, there's a command line to invoke directly the Control Panel, which is javaws -viewer, should work for both openJDK and Oracle's JDK (thanks @Nasser for checking the availability in Oracle's JDK)

Same caution to run as the user you need to access permissions with applies.

Convert JavaScript object to json data

$("form").submit(function(event){
  event.preventDefault();
  var formData = $("form").serializeArray(); // Create array of object
  var jsonConvertedData = JSON.stringify(formData);  // Convert to json
  consol.log(jsonConvertedData);
});

You can validate json data using http://jsonlint.com

Assuming you have two log-files in:

• C:/temp/my.log
• C:/temp/alsoMy.log

cd to C: and use:

grep -r somethingtosearch temp/*.log

It will give you a list like:

temp/my.log:somethingtosearch
temp/alsoMy.log:somethingtosearch1
temp/alsoMy.log:somethingtosearch2

Use some javascript!

I don't like mounting volumes as a link to a host directory, so I came up with a pattern for upgrading docker containers with entirely docker managed containers. Creating a new docker container with --volumes-from <container> will give the new container with the updated images shared ownership of docker managed volumes.

docker pull mysql
docker create --volumes-from my_mysql_container [...] --name my_mysql_container_tmp mysql

By not immediately removing the original my_mysql_container yet, you have the ability to revert back to the known working container if the upgraded container doesn't have the right data, or fails a sanity test.

At this point, I'll usually run whatever backup scripts I have for the container to give myself a safety net in case something goes wrong

docker stop my_mysql_container
docker start my_mysql_container_tmp

Now you have the opportunity to make sure the data you expect to be in the new container is there and run a sanity check.

docker rm my_mysql_container
docker rename my_mysql_container_tmp my_mysql_container

The docker volumes will stick around so long as any container is using them, so you can delete the original container safely. Once the original container is removed, the new container can assume the namesake of the original to make everything as pretty as it was to begin.

There are two major advantages to using this pattern for upgrading docker containers. Firstly, it eliminates the need to mount volumes to host directories by allowing volumes to be directly transferred to an upgraded containers. Secondly, you are never in a position where there isn't a working docker container; so if the upgrade fails, you can easily revert to how it was working before by spinning up the original docker container again.

This should do the trick:

image = open("image.png", "wb")
image.write(base64string.decode('base64'))
image.close()

As per my understanding sys.stdout.flush() pushes out all the data that has been buffered to that point to a file object. While using stdout, data is stored in buffer memory (for some time or until the memory gets filled) before it gets written to terminal. Using flush() forces to empty the buffer and write to terminal even before buffer has empty space.

1. Exact ical format: http://www.ietf.org/rfc/rfc2445.txt
2. According to the spec, it has to end in .ics

Edit: actually I'm not sure - line 6186 gives an example in .ics naming format, but it also states you can use url parameters. I don't think it matters, so long as the MIME type is correct.

Edit: Example from wikipedia: http://en.wikipedia.org/wiki/ICalendar

Use the following code to return a short string:

I recommend that before executing SaveAs, delete the file it exists.

If Dir("f:ull\path\with\filename.xls") <> "" Then
    Kill "f:ull\path\with\filename.xls"

It's easier than setting DisplayAlerts off and on, plus if DisplayAlerts remains off due to code crash, it can cause problems if you work with Excel in the same session.

For those who want to filter from an array of objects using any key:

function filterItems(items, searchVal) {_x000D_
  return items.filter((item) => Object.values(item).includes(searchVal));_x000D_
}_x000D_
let data = [_x000D_
  { "name": "apple", "type": "fruit", "id": 123234 },_x000D_
  { "name": "cat", "type": "animal", "id": 98989 },_x000D_
  { "name": "something", "type": "other", "id": 656565 }]_x000D_
_x000D_
_x000D_
console.log("Filtered by name: ", filterItems(data, "apple"));_x000D_
console.log("Filtered by type: ", filterItems(data, "animal"));_x000D_
console.log("Filtered by id: ", filterItems(data, 656565));

filter from an array of the JSON objects:**

Combining the answers from ratty's and Haim's posts (including comments) I've come up with this, which for SQL Server seems to be the most elegant so far:

-- DROP TABLE #tmpTableSizes
CREATE TABLE #tmpTableSizes
(
    tableName varchar(100),
    numberofRows varchar(100),
    reservedSize varchar(50),
    dataSize varchar(50),
    indexSize varchar(50),
    unusedSize varchar(50)
)
insert #tmpTableSizes
EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"


select  * from #tmpTableSizes
order by cast(LEFT(reservedSize, LEN(reservedSize) - 4) as int)  desc

This gives you a list of all your tables in order of reserved size, ordered from largest to smallest.

Use this echo statement

 echo -e "Hai\nHello\nTesting\n"

The output is

Hai
Hello
Testing

For the EditText if we specify,

android:inputType="number"

only numbers can be got. But if you use,

android:inputType="phone"

along with the numbers it can accept special characters like ;,/". etc.

I landed on this page trying to figure out a sane way to validate strings as "valid" urls. I share here my solution using python3. No extra libraries required.

See https://docs.python.org/2/library/urlparse.html if you are using python2.

See https://docs.python.org/3.0/library/urllib.parse.html if you are using python3 as I am.

import urllib
from pprint import pprint

invalid_url = 'dkakasdkjdjakdjadjfalskdjfalk'
valid_url = 'https://stackoverflow.com'
tokens = [urllib.parse.urlparse(url) for url in (invalid_url, valid_url)]

for token in tokens:
    pprint(token)

min_attributes = ('scheme', 'netloc')  # add attrs to your liking
for token in tokens:
    if not all([getattr(token, attr) for attr in min_attributes]):
        error = "'{url}' string has no scheme or netloc.".format(url=token.geturl())
        print(error)
    else:
        print("'{url}' is probably a valid url.".format(url=token.geturl()))

ParseResult(scheme='', netloc='', path='dkakasdkjdjakdjadjfalskdjfalk', params='', query='', fragment='')

ParseResult(scheme='https', netloc='stackoverflow.com', path='', params='', query='', fragment='')

'dkakasdkjdjakdjadjfalskdjfalk' string has no scheme or netloc.

'https://stackoverflow.com' is probably a valid url.

Here is a more concise function:

from urllib.parse import urlparse

min_attributes = ('scheme', 'netloc')


def is_valid(url, qualifying=min_attributes):
    tokens = urlparse(url)
    return all([getattr(tokens, qualifying_attr)
                for qualifying_attr in qualifying])

What happens in your code if $usertable is not a valid table or doesn't include a column PartNumber or part is not a number.

You must escape $partid and also read the document for mysql_fetch_assoc() because it can return a boolean

First of all, write the following code:

#include <Mmsystem.h>
#include <mciapi.h>
//these two headers are already included in the <Windows.h> header
#pragma comment(lib, "Winmm.lib")

To open *.mp3:

mciSendString("open \"*.mp3\" type mpegvideo alias mp3", NULL, 0, NULL);

To play *.mp3:

mciSendString("play mp3", NULL, 0, NULL);

To play and wait until the *.mp3 has finished playing:

mciSendString("play mp3 wait", NULL, 0, NULL);

To replay (play again from start) the *.mp3:

mciSendString("play mp3 from 0", NULL, 0, NULL);

To replay and wait until the *.mp3 has finished playing:

mciSendString("play mp3 from 0 wait", NULL, 0, NULL);

To play the *.mp3 and replay it every time it ends like a loop:

mciSendString("play mp3 repeat", NULL, 0, NULL);

If you want to do something when the *.mp3 has finished playing, then you need to RegisterClassEx by the WNDCLASSEX structure, CreateWindowEx and process it's messages with the GetMessage, TranslateMessage and DispatchMessage functions in a while loop and call:

mciSendString("play mp3 notify", NULL, 0, hwnd); //hwnd is an handle to the window returned from CreateWindowEx. If this doesn't work, then replace the hwnd with MAKELONG(hwnd, 0).

In the window procedure, add the case MM_MCINOTIFY: The code in there will be executed when the mp3 has finished playing.

But if you program a Console Application and you don't deal with windows, then you can CreateThread in suspend state by specifying the CREATE_SUSPENDED flag in the dwCreationFlags parameter and keep the return value in a static variable and call it whatever you want. For instance, I call it mp3. The type of this static variable is HANDLE of course.

Here is the ThreadProc for the lpStartAddress of this thread:

DWORD WINAPI MP3Proc(_In_ LPVOID lpParameter) //lpParameter can be a pointer to a structure that store data that you cannot access outside of this function. You can prepare this structure before `CreateThread` and give it's address in the `lpParameter`
{
    Data *data = (Data*)lpParameter; //If you call this structure Data, but you can call it whatever you want.
    while (true)
    {
        mciSendString("play mp3 from 0 wait", NULL, 0, NULL);
        //Do here what you want to do when the mp3 playback is over
        SuspendThread(GetCurrentThread()); //or the handle of this thread that you keep in a static variable instead
    }
}

All what you have to do now is to ResumeThread(mp3); every time you want to replay your mp3 and something will happen every time it finishes.

You can #define play_my_mp3 ResumeThread(mp3); to make your code more readable.

Of course you can remove the while (true), SuspendThread and the from 0 codes, if you want to play your mp3 file only once and do whatever you want when it is over.

If you only remove the SuspendThread call, then the sound will play over and over again and do something whenever it is over. This is equivalent to:

mciSendString("play mp3 repeat notify", NULL, 0, hwnd); //or MAKELONG(hwnd, 0) instead

in windows.

To pause the *.mp3 in middle:

mciSendString("pause mp3", NULL, 0, NULL);

and to resume it:

mciSendString("resume mp3", NULL, 0, NULL);

To stop it in middle:

mciSendString("stop mp3", NULL, 0, NULL);

Note that you cannot resume a sound that has been stopped, but only paused, but you can replay it by carrying out the play command. When you're done playing this *.mp3, don't forget to:

mciSendString("close mp3", NULL, 0, NULL);

All these actions also apply to (work with) wave files too, but with wave files, you can use "waveaudio" instead of "mpegvideo". Also you can just play them directly without opening them:

PlaySound("*.wav", GetModuleHandle(NULL), SND_FILENAME);

If you don't want to specify an handle to a module:

sndPlaySound("*.wav", SND_FILENAME);

If you don't want to wait until the playback is over:

PlaySound("*.wav", GetModuleHandle(NULL), SND_FILENAME | SND_ASYNC);
//or
sndPlaySound("*.wav", SND_FILENAME | SND_ASYNC);

To play the wave file over and over again:

PlaySound("*.wav", GetModuleHandle(NULL), SND_FILENAME | SND_ASYNC | SND_LOOP);
//or
sndPlaySound("*.wav", SND_FILENAME | SND_ASYNC | SND_LOOP);

Note that you must specify both the SND_ASYNC and SND_LOOP flags, because you never going to wait until a sound, that repeats itself countless times, is over!

Also you can fopen the wave file and copy all it's bytes to a buffer (an enormous/huge (very big) array of bytes) with the fread function and then:

PlaySound(buffer, GetModuleHandle(NULL), SND_MEMORY);
//or
PlaySound(buffer, GetModuleHandle(NULL), SND_MEMORY | SND_ASYNC);
//or
PlaySound(buffer, GetModuleHandle(NULL), SND_MEMORY | SND_ASYNC | SND_LOOP);
//or
sndPlaySound(buffer, SND_MEMORY);
//or
sndPlaySound(buffer, SND_MEMORY | SND_ASYNC);
//or
sndPlaySound(buffer, SND_MEMORY | SND_ASYNC | SND_LOOP);

Either OpenFile or CreateFile or CreateFile2 and either ReadFile or ReadFileEx functions can be used instead of fopen and fread functions.

Hope this fully answers perfectly your question.

@Adorojan's answer is almost correct. But addition of offset is not correct since offset value will be negative if browser date is ahead of GMT and vice versa. Below is the solution which I came with and is working perfectly fine for me:

// Input time in UTC_x000D_
var inputInUtc = "6/29/2011 4:52:48";_x000D_
_x000D_
var dateInUtc = new Date(Date.parse(inputInUtc+" UTC"));_x000D_
//Print date in UTC time_x000D_
document.write("Date in UTC : " + dateInUtc.toISOString()+"<br>");_x000D_
_x000D_
var dateInLocalTz = convertUtcToLocalTz(dateInUtc);_x000D_
//Print date in local time_x000D_
document.write("Date in Local : " + dateInLocalTz.toISOString());_x000D_
_x000D_
function convertUtcToLocalTz(dateInUtc) {_x000D_
  //Convert to local timezone_x000D_
  return new Date(dateInUtc.getTime() - dateInUtc.getTimezoneOffset()*60*1000);_x000D_
}

You mention two different groupIds, com.morrislgn.merchandising.common and com.johnlewis.jec.webpim.common. Maybe this is the problem.

(Kotlin) In the activity hosting the fragment(s):

    override fun onOptionsItemSelected(item: MenuItem): Boolean {
    when (item.itemId) {
        android.R.id.home -> {
            onBackPressed()
            return true
        }
    }
    return super.onOptionsItemSelected(item)
}

I have found that when I add fragments to a project, they show the action bar home button by default, to remove/disable it put this in onViewCreated() (use true to enable it if it is not showing):

val actionBar = this.requireActivity().actionBar
    actionBar?.setDisplayHomeAsUpEnabled(false)

Magento 1.x

(magento 2 example provided below)

sectionName, groupName and fieldName are present in etc/system.xml file of the module.

PHP Syntax:

Mage::getStoreConfig('sectionName/groupName/fieldName');

From within an editor in the admin, such as the content of a CMS Page or Static Block; the description/short description of a Catalog Category, Catalog Product, etc.

{{config path="sectionName/groupName/fieldName"}}

For the "Within an editor" approach to work, the field value must be passed through a filter for the {{ ... }} contents to be parsed out. Out of the box, Magento will do this for Category and Product descriptions, as well as CMS Pages and Static Blocks. However, if you are outputting the content within your own custom view script and want these variables to be parsed out, you can do so like this:

<?php
    $example = Mage::getModel('identifier/name')->load(1);
    $filter  = Mage::getModel('cms/template_filter');
    echo $filter->filter($example->getData('field'));
?>

Replacing identifier/name with the a appropriate values for the model you are loading, and field with the name of the attribute you want to output, which may contain {{ ... }} occurrences that need to be parsed out.

Magento 2.x

From any Block class that extends \Magento\Framework\View\Element\AbstractBlock

$this->_scopeConfig->getValue('sectionName/groupName/fieldName');

Any other PHP class:

If the class (and none of it's parent's) does not inject \Magento\Framework\App\Config\ScopeConfigInterface via the constructor, you'll have to add it to your class.

// ... Remaining class definition above...

/**
 * @var \Magento\Framework\App\Config\ScopeConfigInterface
 */
protected $_scopeConfig;

/**
 * Constructor
 */
public function __construct(
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    // ...any other injected classes the class depends on...
) {
  $this->_scopeConfig = $scopeConfig;
  // Remaining constructor logic...
}

// ...remaining class definition below...

Once you have injected it into your class, you can now fetch store configuration values with the same syntax example given above for block classes.

Note that after modifying any class's __construct() parameter list, you may have to clear your generated classes as well as dependency injection directory: var/generation & var/di

You need to have a SQLite JDBC driver in your classpath.

Taro L. Saito (xerial) forked the Zentus project and now maintains it under the name sqlite-jdbc. It bundles the native drivers for major platforms so you don't need to configure them separately.

All-In-One Solution

I would personally combine Color Thief along with this modified version of Name that Color to obtain a more-than-sufficient array of dominant color results for images.

Example:

Consider the following image:

You can use the following code to extract image data relating to the dominant color:

let color_thief = new ColorThief();
let sample_image = new Image();

sample_image.onload = () => {
  let result = ntc.name('#' + color_thief.getColor(sample_image).map(x => {
    const hex = x.toString(16);
    return hex.length === 1 ? '0' + hex : hex;
    
  }).join(''));
  
  console.log(result[0]); // #f0c420     : Dominant HEX/RGB value of closest match
  console.log(result[1]); // Moon Yellow : Dominant specific color name of closest match
  console.log(result[2]); // #ffff00     : Dominant HEX/RGB value of shade of closest match
  console.log(result[3]); // Yellow      : Dominant color name of shade of closest match
  console.log(result[4]); // false       : True if exact color match
};

sample_image.crossOrigin = 'anonymous';
sample_image.src = document.getElementById('sample-image').src;

Since the built-in IndexOf function is already optimized for searching a character within a string, an even faster version would be (as extension method):

public static int NthIndexOf(this string input, char value, int n)
{
    if (n <= 0) throw new ArgumentOutOfRangeException("n", n, "n is less than zero.");

    int i = -1;
    do
    {
        i = input.IndexOf(value, i + 1);
        n--;
    }
    while (i != -1 && n > 0);

    return i;
}

Or to search from the end of the string using LastIndexOf:

public static int NthLastIndexOf(this string input, char value, int n)
{
    if (n <= 0) throw new ArgumentOutOfRangeException("n", n, "n is less than zero.");

    int i = input.Length;
    do
    {
        i = input.LastIndexOf(value, i - 1);
        n--;
    }
    while (i != -1 && n > 0);

    return i;
}

Searching for a string instead of a character is as simple as changing the parameter type from char to string and optionally add an overload to specify the StringComparison.

When using TypeScript, the default tab width is always two regardless of what it says in the toolbar. You have to set "prettier.tabWidth" in your user settings to change it.

Ctrl + P, Type ? user settings, add:

"prettier.tabWidth": 4

in my case the solution was to set the proxy to "native" I had configured the proxy under linux with cntlm and also in Firefox (used as eclipse browser also.

DECLARE @chr nvarchar(50) = (SELECT CONVERT(nvarchar(50), GETDATE(), 103))

SELECT @chr chars, CONVERT(date, @chr, 103) date_again

You should chain the replace() together instead of assigning the result and replacing again.

var strMessage1 = document.getElementById("element1") ;
strMessage1.innerHTML = strMessage1.innerHTML
                        .replace(/aaaaaa./g,'<a href=\"http://www.google.com/')
                        .replace(/.bbbbbb/g,'/world\">Helloworld</a>');

Python Force-suppress all exponential notation when printing numpy ndarrays, wrangle text justification, rounding and print options:

What follows is an explanation for what is going on, scroll to bottom for code demos.

Passing parameter suppress=True to function set_printoptions works only for numbers that fit in the default 8 character space allotted to it, like this:

import numpy as np
np.set_printoptions(suppress=True) #prevent numpy exponential 
                                   #notation on print, default False

#            tiny     med  large
a = np.array([1.01e-5, 22, 1.2345678e7])  #notice how index 2 is 8 
                                          #digits wide

print(a)    #prints [ 0.0000101   22.     12345678. ]

However if you pass in a number greater than 8 characters wide, exponential notation is imposed again, like this:

np.set_printoptions(suppress=True)

a = np.array([1.01e-5, 22, 1.2345678e10])    #notice how index 2 is 10
                                             #digits wide, too wide!

#exponential notation where we've told it not to!
print(a)    #prints [1.01000000e-005   2.20000000e+001   1.23456780e+10]

numpy has a choice between chopping your number in half thus misrepresenting it, or forcing exponential notation, it chooses the latter.

Here comes set_printoptions(formatter=...) to the rescue to specify options for printing and rounding. Tell set_printoptions to just print bare a bare float:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:f}'.format})

a = np.array([1.01e-5, 22, 1.2345678e30])  #notice how index 2 is 30
                                           #digits wide.  

#Ok good, no exponential notation in the large numbers:
print(a)  #prints [0.000010 22.000000 1234567799999999979944197226496.000000] 

We've force-suppressed the exponential notation, but it is not rounded or justified, so specify extra formatting options:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:0.2f}'.format})  #float, 2 units 
                                               #precision right, 0 on left

a = np.array([1.01e-5, 22, 1.2345678e30])   #notice how index 2 is 30
                                            #digits wide

print(a)  #prints [0.00 22.00 1234567799999999979944197226496.00]

The drawback for force-suppressing all exponential notion in ndarrays is that if your ndarray gets a huge float value near infinity in it, and you print it, you're going to get blasted in the face with a page full of numbers.

Notice that rounding is consistent at 2 units precision, and exponential notation is suppressed in both the very large e+x and very small e-x ranges.

jQuery's .eq() can help you traverse through elements with an indexed approach.

var testimonialElements = $(".testimonial");
for(var i=0; i<testimonialElements.length; i++){
    var element = testimonialElements.eq(i);
    //do something with element
}

The request method getRequestDispatcher() can be used for referring to local servlets within single webapp.

Servlet context based getRequestDispatcher() method can used of referring servlets from other web applications deployed on SAME server.

I believe that you can omit updating the "non-desired" columns by adjusting the other answers as follows:

update table set
    columnx = (case when condition1 then 25 end),
    columny = (case when condition2 then 25 end)`

As I understand it, this will update only when the condition is met.

After reading all the comments, this is the most efficient:

Update table set ColumnX = 25 where Condition1
 Update table set ColumnY = 25 where Condition1`

Sample Table:

CREATE TABLE [dbo].[tblTest](
    [ColX] [int] NULL,
    [ColY] [int] NULL,
    [ColConditional] [bit] NULL,
    [id] [int] IDENTITY(1,1) NOT NULL
) ON [PRIMARY]

Sample Data:

Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 0)
Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 0)
Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 1)
Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 1)
Insert into tblTest (ColX, ColY, ColConditional) values (1, null, null)
Insert into tblTest (ColX, ColY, ColConditional) values (2, null, null)
Insert into tblTest (ColX, ColY, ColConditional) values (null, 1, null)
Insert into tblTest (ColX, ColY, ColConditional) values (null, 2, null)

Now I assume you can write a conditional that handles nulls. For my example, I am assuming you have written such a conditional that evaluates to True, False or Null. If you need help with this, let me know and I will do my best.

Now running these two lines of code does infact change X to 25 if and only if ColConditional is True(1) and Y to 25 if and only if ColConditional is False(0)

Update tblTest set ColX = 25 where ColConditional = 1
Update tblTest set ColY = 25 where ColConditional = 0

P.S. The null case was never mentioned in the original question or any updates to the question, but as you can see, this very simple answer handles them anyway.

String path = System.getProperty("user.dir")+"/config.xml";
File f=new File(path);

You can set label's border via its underlying CALayer property:

#import <QuartzCore/QuartzCore.h>

myLabel.layer.borderColor = [UIColor greenColor].CGColor
myLabel.layer.borderWidth = 3.0

Swift 5:

myLabel.layer.borderColor = UIColor.darkGray.cgColor
myLabel.layer.borderWidth = 3.0

You can use plenty of things.

• If you're a standards junkie, you can use the HTML5 <audio> tag:

Here is the official W3C specification for the audio tag.

Usage:

<audio controls>
 <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.mp4"
         type='audio/mp4'>
 <!-- The next two lines are only executed if the browser doesn't support MP4 files -->
 <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.oga"
         type='audio/ogg; codecs=vorbis'>
 <!-- The next line will only be executed if the browser doesn't support the <audio> tag-->
 <p>Your user agent does not support the HTML5 Audio element.</p>
</audio>

jsFiddle here.

• Or, if you want to support older browsers, you can use many of the free audio flash players available. Such as:

  • Dewplayer
  • MP3 Player (boring name... right? :) )
  • Website Music Player (even more boring... right?)
  • Zanorg Player

Note: I'm not sure which are the best ones, as I have never used one (yet).

UPDATE: As mentioned in another answer's comment, you are using XHTML 1.0 Transitional. You might be able to get <audio> to work with some hack.

UPDATE 2: I just remembered another way to do play audio. This will work in XHTML!!! This is fully standards-compliant.

You use this JavaScript:

var aud = document.createElement("iframe");
aud.setAttribute('src', "http://yoursite.com/youraudio.mp4"); // replace with actual file path
aud.setAttribute('width', '1px');
aud.setAttribute('height', '1px');
aud.setAttribute('scrolling', 'no');
aud.style.border = "0px";
document.body.appendChild(aud);

This is my answer to another question.

UPDATE 3: To customise the controls, you can use something like this.
