RFC 2616, section 14.9.1:

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.

Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.

For me, a more concrete example of Cache-Control: private is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.

FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.

This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.

Just loop the array and convert items:

for(var i=0, len=count_array.length; i<len; i++){
    count_array[i] = parseInt(count_array[i], 10);
}

Don't forget the second argument for parseInt.

Along with WSDL, I had xsd files. The above did not work in my case gave error. It worked as follows

wsdl /l:C# /out:D:\FileName.cs D:\NameApi\wsdl_1_1\RESAdapterService.wsdl 
D:\CXTypes.xsd D:\CTypes.xsd 
D:\Preferences.xsd 

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

I have also used a non-generic version, using the new keyword:

public interface IMetadata
{
    Type DataType { get; }

    object Data { get; }
}

public interface IMetadata<TData> : IMetadata
{
    new TData Data { get; }
}

Explicit interface implementation is used to allow both Data members:

public class Metadata<TData> : IMetadata<TData>
{
    public Metadata(TData data)
    {
       Data = data;
    }

    public Type DataType
    {
        get { return typeof(TData); }
    }

    object IMetadata.Data
    {
        get { return Data; }
    }

    public TData Data { get; private set; }
}

You could derive a version targeting value types:

public interface IValueTypeMetadata : IMetadata
{

}

public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{

}

public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
    public ValueTypeMetadata(TData data) : base(data)
    {}
}

This can be extended to any kind of generic constraints.

Two suggestions:

1. Use std::deque instead of std::vector for better performance in your specific case and use the method std::deque::pop_front().
2. Rethink (I mean: delete) the & in std::vector<ScanRule>& topPriorityRules;

I couldn't get the above code to work.

Google does a great explanation though here: http://code.google.com/apis/maps/documentation/javascript/basics.html#DetectingUserLocation

Where they first use the W3C Geolocation method and then offer the Google.gears fallback method for older browsers.

The example is here:

http://code.google.com/apis/maps/documentation/javascript/examples/map-geolocation.html

You can patch the IP of Node where pods are hosted ( Private IP of Node ) , this is the easy workaround .

Taking reference with above posts , Following worked for me :

kubectl patch service my-loadbalancer-service-name \ -n lb-service-namespace \ -p '{"spec": {"type": "LoadBalancer", "externalIPs":["xxx.xxx.xxx.xxx Private IP of Physical Server - Node - where deployment is done "]}}'

As of Jan 2020 and WordPress v5.3.2, I confirm the following works fine.

It will include the field keys with their equivalent underscore keys as well, but I guess if you properly "enum" your keys in your code, that should be no problem:

$meta_values   = get_post_meta( get_the_ID() );
$example_field = meta_values['example_field_key'][0];

//OR if you do enum style 
//(emulation of a class with a list of *const* as enum does not exist in PHP per se)
$example_field = meta_values[PostTypeEnum::FIELD_EXAMPLE_KEY][0]; 

As the print_r(meta_values); gives:

Array
(
    [_edit_lock] => Array
        (
            [0] => 1579542560:1
        )

    [_edit_last] => Array
        (
            [0] => 1
        )

    [example_field] => Array
        (
            [0] => 13
        )
)

Hope that helps someone, go make a ruckus!

Based on the Answer marked as correct, adding my answer. Small code added just to reset the indices-

$input = array_values(array_map("unserialize", array_unique(array_map("serialize", $inputArray))));

The django shell is the good way to execute a python module with the django environment, but it is not always easy and tiresome to import modules and execute functions manually especially without auto-completion. To resolve this, I created a small shell script "runscript.sh" that allows you to take full advantage of the auto-completion and the log history of the Linux console.

NB: Copy runscript.sh to the root project and set the execute right (chmod +x)

For example: I want to run python function named show(a, b, c) in module do_somethings.py in myapp/do_folder/

The standard django way (manage.py shell):

python3 manage.py shell
 > from myapp.do_folder import do_somethings
 > do_somethings.show("p1", "p2"  , 3.14159)

With script (runscript.sh):

./runscript.sh myapp/do_folder/do_somethings.py show p1 p2 3.14159

The script is not limited in number of arguments. However only arguments of primitive types are supported (int, float, string)

If you know you're going to have a limited number of max options then I would try this (example for max of 4 options per order):

Select OI.ID, OI.Item_Name, OO1.Value, OO2.Value, OO3.Value, OO4.Value

FROM Ordered_Items OI
    LEFT JOIN Ordered_Options OO1 ON OO1.Ordered_Item_ID = OI.ID
    LEFT JOIN Ordered_Options OO2 ON OO2.Ordered_Item_ID = OI.ID AND OO2.ID != OO1.ID
    LEFT JOIN Ordered_Options OO3 ON OO3.Ordered_Item_ID = OI.ID AND OO3.ID != OO1.ID AND OO3.ID != OO2.ID
    LEFT JOIN Ordered_Options OO4 ON OO4.Ordered_Item_ID = OI.ID AND OO4.ID != OO1.ID AND OO4.ID != OO2.ID AND OO4.ID != OO3.ID

GROUP BY OI.ID, OI.Item_Name

The group by condition gets rid of all of the duplicates that you would otherwise get. I've just implemented something similar on a site I'm working on where I knew I'd always have 1 or 2 matched in my child table, and I wanted to make sure I only had 1 row for each parent item.

None of the previously given examples were meeting my needs completely, so I wrote my own queue that allows following functionality: iteration, index access, indexOf, lastIndexOf, get first, get last, offer, remaining capacity, expand capacity, dequeue last, dequeue first, enqueue / add element, dequeue / remove element, subQueueCopy, subArrayCopy, toArray, snapshot, basics like size, remove or contains.

Garbage collection

The browsers garbage collection has no idea if the code that's eval'ed can be removed from memory so it just keeps it stored until the page is reloaded. Not too bad if your users are only on your page shortly, but it can be a problem for webapp's.

Here's a script to demo the problem

https://jsfiddle.net/CynderRnAsh/qux1osnw/

document.getElementById("evalLeak").onclick = (e) => {
  for(let x = 0; x < 100; x++) {
    eval(x.toString());
  }
};

Something as simple as the above code causes a small amount of memory to be store until the app dies. This is worse when the evaled script is a giant function, and called on interval.

I would try formatting your table correctly first off like so:

I cannot help but thinking that formatting the table could at the very least not do any harm.

<table>
   <thead>
      <th>Header1</th>
      ......
   </thead>
   <tbody>
       <tr><td>Content1</td>....</tr>
       ......
   </tbody>
</table>

python3 -m virtualenv virtualenv_name

python -m virtualenv virtualenv_name

PEP 3101 proposes the replacement of the % operator with the new, advanced string formatting in Python 3, where it would be the default.

Think of a GrantedAuthority as being a "permission" or a "right". Those "permissions" are (normally) expressed as strings (with the getAuthority() method). Those strings let you identify the permissions and let your voters decide if they grant access to something.

You can grant different GrantedAuthoritys (permissions) to users by putting them into the security context. You normally do that by implementing your own UserDetailsService that returns a UserDetails implementation that returns the needed GrantedAuthorities.

Roles (as they are used in many examples) are just "permissions" with a naming convention that says that a role is a GrantedAuthority that starts with the prefix ROLE_. There's nothing more. A role is just a GrantedAuthority - a "permission" - a "right". You see a lot of places in spring security where the role with its ROLE_ prefix is handled specially as e.g. in the RoleVoter, where the ROLE_ prefix is used as a default. This allows you to provide the role names withtout the ROLE_ prefix. Prior to Spring security 4, this special handling of "roles" has not been followed very consistently and authorities and roles were often treated the same (as you e.g. can see in the implementation of the hasAuthority() method in SecurityExpressionRoot - which simply calls hasRole()). With Spring Security 4, the treatment of roles is more consistent and code that deals with "roles" (like the RoleVoter, the hasRole expression etc.) always adds the ROLE_ prefix for you. So hasAuthority('ROLE_ADMIN') means the the same as hasRole('ADMIN') because the ROLE_ prefix gets added automatically. See the spring security 3 to 4 migration guide for futher information.

But still: a role is just an authority with a special ROLE_ prefix. So in Spring security 3 @PreAuthorize("hasRole('ROLE_XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')") and in Spring security 4 @PreAuthorize("hasRole('XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')").

Regarding your use case:

Users have roles and roles can perform certain operations.

You could end up in GrantedAuthorities for the roles a user belongs to and the operations a role can perform. The GrantedAuthorities for the roles have the prefix ROLE_ and the operations have the prefix OP_. An example for operation authorities could be OP_DELETE_ACCOUNT, OP_CREATE_USER, OP_RUN_BATCH_JOBetc. Roles can be ROLE_ADMIN, ROLE_USER, ROLE_OWNER etc.

You could end up having your entities implement GrantedAuthority like in this (pseudo-code) example:

@Entity
class Role implements GrantedAuthority {
    @Id
    private String id;

    @ManyToMany
    private final List<Operation> allowedOperations = new ArrayList<>();

    @Override
    public String getAuthority() {
        return id;
    }

    public Collection<GrantedAuthority> getAllowedOperations() {
        return allowedOperations;
    }
}

@Entity
class User {
    @Id
    private String id;

    @ManyToMany
    private final List<Role> roles = new ArrayList<>();

    public Collection<Role> getRoles() {
        return roles;
    }
}

@Entity
class Operation implements GrantedAuthority {
    @Id
    private String id;

    @Override
    public String getAuthority() {
        return id;
    }
}

The ids of the roles and operations you create in your database would be the GrantedAuthority representation, e.g. ROLE_ADMIN, OP_DELETE_ACCOUNT etc. When a user is authenticated, make sure that all GrantedAuthorities of all its roles and the corresponding operations are returned from the UserDetails.getAuthorities() method.

Example: The admin role with id ROLE_ADMIN has the operations OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB assigned to it. The user role with id ROLE_USER has the operation OP_READ_ACCOUNT.

If an admin logs in the resulting security context will have the GrantedAuthorities: ROLE_ADMIN, OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB

If a user logs it, it will have: ROLE_USER, OP_READ_ACCOUNT

The UserDetailsService would take care to collect all roles and all operations of those roles and make them available by the method getAuthorities() in the returned UserDetails instance.

ls -lR is to display all files, directories and sub directories of the current directory ls -lR | more is used to show all the files in a flow.

You're talking about right-clicking on a table and selecting "Edit Top 50 Rows", right?

I tried [Ctl][Enter] and [Alt][Enter], but neither of those works.

Even when I insert data with CR/LF (using a standard INSERT statement), it shows up here in a single line with a rectangle representing the control codes.

You can use gdb, but I would first try Valgrind. See the quick start guide.

Briefly, Valgrind instruments your program so it can detect several kinds of errors in using dynamically allocated memory, such as double frees and writes past the end of allocated blocks of memory (which can corrupt the heap). It detects and reports the errors as soon as they occur, thus pointing you directly to the cause of the problem.

Try to understand through this below function using python3

def floating_decimals(f_val, dec):
    prc = "{:."+str(dec)+"f}" #first cast decimal as str
    print(prc) #str format output is {:.3f}
    return prc.format(f_val)


print(floating_decimals(50.54187236456456564, 3))

Output is : 50.542

Hope this helps you!

The workaround is simple. Just use the Uri().ToString() method and percent-encode white-spaces, if any, afterwards.

string path = new Uri("C:\my example?.txt").ToString().Replace(" ", "%20");

properly returns file:///C:/my%20example?.txt

As others have suggested that you should look into MERGE statement but nobody provided a solution using it I'm adding my own answer with this particular TSQL construct. I bet you'll like it.

Important note

Your code has a typo in your if statement in not exists(select...) part. Inner select statement has only one where condition while UserName condition is excluded from the not exists due to invalid brace completion. In any case you cave too many closing braces.

I assume this based on the fact that you're using two where conditions in update statement later on in your code.

Let's continue to my answer...

SQL Server 2008+ support MERGE statement

MERGE statement is a beautiful TSQL gem very well suited for "insert or update" situations. In your case it would look similar to the following code. Take into consideration that I'm declaring variables what are likely stored procedure parameters (I suspect).

declare @clockDate date = '08/10/2012';
declare @userName = 'test';

merge Clock as target
using (select @clockDate, @userName) as source (ClockDate, UserName)
on (target.ClockDate = source.ClockDate and target.UserName = source.UserName)
when matched then
    update
    set BreakOut = getdate()
when not matched then
    insert (ClockDate, UserName, BreakOut)
    values (getdate(), source.UserName, getdate());

If you've added your own custom configuration sections to your App.Config, make sure you have defined the section in the <configSections> element. I added the my config XML but forgot to declare the configuration section up top - which caused the exception "Configuration system failed to initialize" for me.

Based on Mohamed23gharbi's answer:

function change(selector, value) {
    var sortBySelect = document.querySelector(selector);
    sortBySelect.value = value;
    sortBySelect.dispatchEvent(new Event("change"));
}

function click(selector) {
    var sortBySelect = document.querySelector(selector);
    sortBySelect.dispatchEvent(new Event("click"));
}

function test() {
    change("select#MySelect", 19);
    click("button#MyButton");
    click("a#MyLink");
}

In my case, where the elements were created by vue, this is the only way that works.

Below script gets job status for every job on the server. It also tells how many steps are there and what is the currently running step and elasped time.

SELECT sj.Name,
    CASE
        WHEN sja.start_execution_date IS NULL THEN 'Never ran'
        WHEN sja.start_execution_date IS NOT NULL AND sja.stop_execution_date IS NULL THEN 'Running'
        WHEN sja.start_execution_date IS NOT NULL AND sja.stop_execution_date IS NOT NULL THEN 'Not running'
    END AS 'RunStatus',
    CASE WHEN sja.start_execution_date IS NOT NULL AND sja.stop_execution_date IS NULL then js.StepCount else null end As TotalNumberOfSteps,
    CASE WHEN sja.start_execution_date IS NOT NULL AND sja.stop_execution_date IS NULL then ISNULL(sja.last_executed_step_id+1,js.StepCount) else null end as currentlyExecutingStep,
    CASE WHEN sja.start_execution_date IS NOT NULL AND sja.stop_execution_date IS NULL then datediff(minute, sja.run_requested_date, getdate()) ELSE NULL end as ElapsedTime
FROM msdb.dbo.sysjobs sj
JOIN msdb.dbo.sysjobactivity sja
ON sj.job_id = sja.job_id
CROSS APPLY (SELECT COUNT(*) FROM msdb.dbo.sysjobsteps as js WHERE js.job_id = sj.job_id) as js(StepCount)
WHERE session_id = (
    SELECT MAX(session_id) FROM msdb.dbo.sysjobactivity)
ORDER BY RunStatus desc

Option 1 using an InputStreamResource

Resource implementation for a given InputStream.

Should only be used if no other specific Resource implementation is > applicable. In particular, prefer ByteArrayResource or any of the file-based Resource implementations where possible.

@RequestMapping(path = "/download", method = RequestMethod.GET)
public ResponseEntity<Resource> download(String param) throws IOException {

    // ...

    InputStreamResource resource = new InputStreamResource(new FileInputStream(file));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}

Option2 as the documentation of the InputStreamResource suggests - using a ByteArrayResource:

@RequestMapping(path = "/download", method = RequestMethod.GET)
public ResponseEntity<Resource> download(String param) throws IOException {

    // ...

    Path path = Paths.get(file.getAbsolutePath());
    ByteArrayResource resource = new ByteArrayResource(Files.readAllBytes(path));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}

Also check for any long running processes executed from your .NET app against the DB. For example you may be calling a stored procedure or query which does not have enough time to finish which can show in your logs as:

• Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

  • This SqlTransaction has completed; it is no longer usable.

Check the command timeout settings Try to run a trace (profiler) and see what is happening on the DB side...

I will try to cover it with examples:

Lock: One example where you would use lock would be a shared dictionary into which items (that must have unique keys) are added.
The lock would ensure that one thread does not enter the mechanism of code that is checking for item being in dictionary while another thread (that is in the critical section) already has passed this check and is adding the item. If another thread tries to enter a locked code, it will wait (be blocked) until the object is released.

private static readonly Object obj = new Object();

lock (obj) //after object is locked no thread can come in and insert item into dictionary on a different thread right before other thread passed the check...
{
    if (!sharedDict.ContainsKey(key))
    {
        sharedDict.Add(item);
    }
}

Semaphore: Let's say you have a pool of connections, then an single thread might reserve one element in the pool by waiting for the semaphore to get a connection. It then uses the connection and when work is done releases the connection by releasing the semaphore.

Code example that I love is one of bouncer given by @Patric - here it goes:

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;

namespace TheNightclub
{
    public class Program
    {
        public static Semaphore Bouncer { get; set; }

        public static void Main(string[] args)
        {
            // Create the semaphore with 3 slots, where 3 are available.
            Bouncer = new Semaphore(3, 3);

            // Open the nightclub.
            OpenNightclub();
        }

        public static void OpenNightclub()
        {
            for (int i = 1; i <= 50; i++)
            {
                // Let each guest enter on an own thread.
                Thread thread = new Thread(new ParameterizedThreadStart(Guest));
                thread.Start(i);
            }
        }

        public static void Guest(object args)
        {
            // Wait to enter the nightclub (a semaphore to be released).
            Console.WriteLine("Guest {0} is waiting to entering nightclub.", args);
            Bouncer.WaitOne();          

            // Do some dancing.
            Console.WriteLine("Guest {0} is doing some dancing.", args);
            Thread.Sleep(500);

            // Let one guest out (release one semaphore).
            Console.WriteLine("Guest {0} is leaving the nightclub.", args);
            Bouncer.Release(1);
        }
    }
}

Mutex It is pretty much Semaphore(1,1) and often used globally (application wide otherwise arguably lock is more appropriate). One would use global Mutex when deleting node from a globally accessible list (last thing you want another thread to do something while you are deleting the node). When you acquire Mutex if different thread tries to acquire the same Mutex it will be put to sleep till SAME thread that acquired the Mutex releases it.

Good example on creating global mutex is by @deepee

class SingleGlobalInstance : IDisposable
{
    public bool hasHandle = false;
    Mutex mutex;

    private void InitMutex()
    {
        string appGuid = ((GuidAttribute)Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(GuidAttribute), false).GetValue(0)).Value.ToString();
        string mutexId = string.Format("Global\\{{{0}}}", appGuid);
        mutex = new Mutex(false, mutexId);

        var allowEveryoneRule = new MutexAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), MutexRights.FullControl, AccessControlType.Allow);
        var securitySettings = new MutexSecurity();
        securitySettings.AddAccessRule(allowEveryoneRule);
        mutex.SetAccessControl(securitySettings);
    }

    public SingleGlobalInstance(int timeOut)
    {
        InitMutex();
        try
        {
            if(timeOut < 0)
                hasHandle = mutex.WaitOne(Timeout.Infinite, false);
            else
                hasHandle = mutex.WaitOne(timeOut, false);

            if (hasHandle == false)
                throw new TimeoutException("Timeout waiting for exclusive access on SingleInstance");
        }
        catch (AbandonedMutexException)
        {
            hasHandle = true;
        }
    }


    public void Dispose()
    {
        if (mutex != null)
        {
            if (hasHandle)
                mutex.ReleaseMutex();
            mutex.Dispose();
        }
    }
}

then use like:

using (new SingleGlobalInstance(1000)) //1000ms timeout on global lock
{
    //Only 1 of these runs at a time
    GlobalNodeList.Remove(node)
}

Hope this saves you some time.

Execute this at the terminal to see conflicting configurations listening to the same port:

grep -R default_server /etc/nginx

Using this code you can check at least one checkbox is selected or not in different checkbox groups or from multiple checkboxes. Using this you can not require to remove IDs or dynamic IDs. This code work with the same IDs.

I'm sticking to the question as the title states and not the discussion. Which view is top visible on any given point?

@implementation UIView (Extra)

- (UIView *)findTopMostViewForPoint:(CGPoint)point
{
    for(int i = self.subviews.count - 1; i >= 0; i--)
    {
        UIView *subview = [self.subviews objectAtIndex:i];
        if(!subview.hidden && CGRectContainsPoint(subview.frame, point))
        {
            CGPoint pointConverted = [self convertPoint:point toView:subview];
            return [subview findTopMostViewForPoint:pointConverted];
        }
    }

    return self;
}

- (UIWindow *)topmostWindow
{
    UIWindow *topWindow = [[[UIApplication sharedApplication].windows sortedArrayUsingComparator:^NSComparisonResult(UIWindow *win1, UIWindow *win2) {
        return win1.windowLevel - win2.windowLevel;
    }] lastObject];
    return topWindow;
}

@end

Can be used directly with any UIWindow as receiver or any UIView as receiver.

This is due to the fact that your element is dynamically created. You should use event delegation to handle the event.

 document.addEventListener('click',function(e){
    if(e.target && e.target.id== 'brnPrepend'){
          //do something
     }
 });

jquery makes it easier:

 $(document).on('click','#btnPrepend',function(){//do something})

Here is an article about event delegation event delegation article

1. Install dotenv as devDependencies:

npm i --save-dev dotenv

2. Create a .env file in the root directory:

my-react-app/
|- node-modules/
|- public/
|- src/
|- .env
|- .gitignore
|- package.json
|- package.lock.json.
|- README.md

3. Update the .env file like below & REACT_APP_ is the compulsory prefix for the variable name.

REACT_APP_BASE_URL=http://localhost:8000
REACT_APP_API_KEY=YOUR-API-KEY

4. [ Optional but Good Practice ] Now you can create a configuration file to store the variables and export the variable so can use it from others file.

For example, I've create a file named base.js and update it like below:

export const BASE_URL = process.env.REACT_APP_BASE_URL;
export const API_KEY = process.env.REACT_APP_API_KEY;

5. Or you can simply just call the environment variable in your JS file in the following way:

process.env.REACT_APP_BASE_URL

A static variable inside a function has a lifespan as long as your program runs. It won't be allocated every time your function is called and deallocated when your function returns.

I've used VideoCapX for our project. It will stream out as MMS/ASF stream which can be open by media player. You can then embed media player into your webpage.

If you won't need much control, or if you want to try out VideoCapX without writing a code, try U-Broadcast, they use VideoCapX behind the scene.

Your curtime variable holds the number of seconds since the epoch. If you get one before and one after, the later one minus the earlier one is the elapsed time in seconds. You can subtract time_t values just fine.

GOTCHA: If you are having trouble with any of the many-starred suggestions, ensure that you are registering your UITableViewCells in viewDidLoad(), not from init()

For anyone who wants to download an image WITHOUT saving it to a file:

Image DownloadImage(string fromUrl)
{
    using (System.Net.WebClient webClient = new System.Net.WebClient())
    {
        using (Stream stream = webClient.OpenRead(fromUrl))
        {
            return Image.FromStream(stream);
        }
    }
}

Would something like this work for you?

SELECT * FROM FB WHERE Dte >= DATE(NOW() - INTERVAL 2 MONTH);

I had the same problem, This is what I did: I have a SPA with multiple views in the same page (without ajax), so this is the code of the module:

var app = angular.module('otisApp', ['chieffancypants.loadingBar', 'ngRoute']);

app.config(['$routeProvider', function($routeProvider){
    $routeProvider.when('/:page', {
        templateUrl: function(page){return page.page + '.html';},
        controller:'otisCtrl'
    })
    .otherwise({redirectTo:'/otis'});
}]);

I have only one controller for all views, but, the problem is the same as the question, the controller always refresh data, in order to avoid this behavior I did what people suggest above and I created a service for that purpose, then pass it to the controller as follows:

app.factory('otisService', function($http){
    var service = {            
        answers:[],
        ...

    }        
    return service;
});

app.controller('otisCtrl', ['$scope', '$window', 'otisService', '$routeParams',  
function($scope, $window, otisService, $routeParams){        
    $scope.message = "Hello from page: " + $routeParams.page;
    $scope.update = function(answer){
        otisService.answers.push(answers);
    };
    ...
}]);

Now I can call the update function from any of my views, pass values and update my model, I haven't no needed to use html5 apis for persistence data (this is in my case, maybe in other cases would be necessary to use html5 apis like localstorage and other stuff).

I found a free plugin that can generate class diagrams with android studio. It's called SimpleUML.

Update Android Studio 2.2+: To install the plugin, follow steps in this answer: https://stackoverflow.com/a/36823007/1245894

Older version of Android Studio On Mac: go to Android Studio -> Preferences -> Plugins

On Windows: go to Android Studio -> File -> Settings -> Plugins

Click on Browse repositories... and search for SimpleUMLCE (CE means Community Edition, this is what android studio is based on).

Install it, restart, then you can do a right click on the folder containing the classes you want to visualize, and select Add to simpleUML Diagram.

That's it; you have you fancy class diagram generated from your code!

In ExtJs, you can use

xtype: 'image'

to render a image.

Here is a fiddle showing rendering of binary data with extjs.

atob -- > converts ascii to binary

btoa -- > converts binary to ascii

Ext.application({
    name: 'Fiddle',

    launch: function () {
        var srcBase64 = "data:image/jpeg;base64," + btoa(atob("iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8H8hYDwAFegHS8+X7mgAAAABJRU5ErkJggg=="));

        Ext.create("Ext.panel.Panel", {
            title: "Test",
            renderTo: Ext.getBody(),
            height: 400,
            items: [{
                xtype: 'image',
                width: 100,
                height: 100,
                src: srcBase64
            }]
        })
    }
});

In my case this Microsoft.Owin.Host.SystemWeb package is present in the project.

But below two tags are not present in web.config.

<add key="owin:AutomaticAppStartup" value="true" />
<add key="owin:appStartup" value="namespace.className.methodName" />

after adding them it works smoothly.

All the previous solutions hard-code 40 pixels specifically into the html or CSS in one fashion or another. What if the navbar contains a different font-size or an image? What if I have a good reason not to mess with the body padding in the first place? I have been searching for a solution to this problem, and here is what I came up with:

$(document).ready(function(){
    $('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height()) + 1 )+'px'});
    $(window).resize(function(){
        $('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height()) + 1 )+'px'});
});

You can move it up or down by adjusting the '1'. It seems to work for me regardless of the size of the content in the navbar, before and after resizing.

I am curious what others think about this: please share your thoughts. (It will be refactored as not to repeat, btw.) Besides using jQuery, are there any other reasons not to approach the problem this way? I've even got it working with a secondary navbar like this:

$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height())
        + $('.admin-nav').height() + 1 )+'px'});

PS: Above is on Bootstrap 2.3.2 - will it work in 3.x As long as the generic class names remain... in fact, it should work independent of bootstrap, right?

EDIT: Here is a complete jquery function that handles two stacked, responsive fixed navbars of dynamic size. It requires 3 html classes(or could use id's): user-top, admin-top, and contentwrap:

$(document).ready(function(){

    $('.admin-top').css({'margin-top':($('.user-top').height()+0)+'px'});
    $('.contentwrap') .css({'padding-top': (
        $('.user-top').height()
         + $('.admin-top').height()
         + 0 )+'px'
    });

    $(window).resize(function(){
        $('.admin-top').css({'margin-top':($('.user-top').height()+0)+'px'});
        $('.contentwrap') .css({'padding-top': (
            $('.user-top').height()
             + $('.admin-top').height()
             + 0 )+'px'
        });
});

Question is about merging two images, however in this specified case you shouldn't do that. You should put Content Image (ie. cover) into <img /> tag, and Style Image into CSS, why?

1. As I said the cover belongs to the content of the document, while that vinyl record and shadow are just a part of the page styles.
2. Such separation is much more convenient to use. User can easily copy that image. It's easier to index by web-spiders.
3. Finally, it's much easier to maintain.

So use a very simple code:

<div class="cover">
   <img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>

.cover {
    padding: 10px;
    padding-right: 100px;

    background: url(/style/images/cover-background.png) no-repeat;
}

I bet your machine's culture is not "en-US". From the documentation:

If provider is a null reference (Nothing in Visual Basic), the current culture is used.

If your current culture is not "en-US", this would explain why it works for me but doesn't work for you and works when you explicitly specify the culture to be "en-US".

The best approach I've found so far is to set a background view of the cell and clear background of cell subviews. Of course, this looks nice on tables with indexed style only, no matter with or without accessories.

Here is a sample where cell's background is panted yellow:

UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ];
backgroundView.backgroundColor = [ UIColor yellowColor ];
cell.backgroundView = backgroundView;
for ( UIView* view in cell.contentView.subviews ) 
{
    view.backgroundColor = [ UIColor clearColor ];
}

If you need absolute URL of the file, use below code:

$file_path = \Storage::url($filename);
$url = asset($file_path);
// Output: http://example.com/storage/filename.jpg

Declarations of public functions go in header files, yes, but definitions are absolutely valid in headers as well! You may declare the definition as static (only 1 copy allowed for the entire program) if you are defining things in a header for utility functions that you don't want to have to define again in each c file. I.E. defining an enum and a static function to translate the enum to a string. Then you won't have to rewrite the enum to string translator for each .c file that includes the header. :)

Just walk over markers and remove them from map, empty maps markers array after that:

var markers = map.markers;
for(var i = 0; i < markers.length; i++) {
    markers[i].setMap(null);
}
map.markers = [];

Trapping CHLD signal may not work because you can lose some signals if they arrived simultaneously.

#!/bin/bash

trap 'rm -f $tmpfile' EXIT

tmpfile=$(mktemp)

doCalculations() {
    echo start job $i...
    sleep $((RANDOM % 5)) 
    echo ...end job $i
    exit $((RANDOM % 10))
}

number_of_jobs=10

for i in $( seq 1 $number_of_jobs )
do
    ( trap "echo job$i : exit value : \$? >> $tmpfile" EXIT; doCalculations ) &
done

wait 

i=0
while read res; do
    echo "$res"
    let i++
done < "$tmpfile"

echo $i jobs done !!!

I think I have the solution to your question, assuming you can use flexbox in your project. What you want to do is make #one a flexbox using display: flex and use flex-direction: column to make it a column alignment.

If you have any other type of files, like sql files

copy *.sql all.sql

You could use lsof to see what application is listening on port 80:

sudo lsof -i TCP:80

You can create a defaultdict

from collections import defaultdict
d1 = defaultdict(int)      # defaults to 0 values for keys
unq = set(lst1)              # lst1 = [1, 2, 2, 3, 4, 1, 2, 7]
for each in unq:
      d1[each] = lst1.count(each)
else:
      print(d1)

I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.

I had <meta http-equiv="x-ua-compatible" content="ie=edge"> on the page.

In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.

With Nginx you can take advantage of the "x-forwarded-proto" header:

function ensureSec(req, res, next){
    if (req.headers["x-forwarded-proto"] === "https"){
       return next();
    }
    res.redirect("https://" + req.headers.host + req.url);  
}

There is no real solution to this - even in the links to other questions given above. In the end I have decided to use setTimeout and call a method that checks every second! Not an ideal solution, but a solution that works and code I am calling is simple enough to not have an effect on performance by being called all the time.

function InitPageControls() {
        CheckIfChanged();
    }

    function CheckIfChanged() {
        // do logic

        setTimeout(function () {
            CheckIfChanged();
        }, 1000);
    }

Hope this helps someone in the future as it seems there is no surefire way of acheiving this using event handlers...

What works, is to enter a relative path or an absolute without the file://-protocol:

• ../my.json leads to file:///D:/swagger-ui/dist/index.html/../my.json and works
• /D:/swagger-ui/dist/my.json leads to file:///D:/swagger-ui/dist/my.json and works

This answer works with Firefox on Win7. For Chrome-Browser, see comments below:

https://developers.google.com/web/updates/2017/09/abortable-fetch

https://dom.spec.whatwg.org/#aborting-ongoing-activities

// setup AbortController
const controller = new AbortController();
// signal to pass to fetch
const signal = controller.signal;

// fetch as usual
fetch(url, { signal }).then(response => {
  ...
}).catch(e => {
  // catch the abort if you like
  if (e.name === 'AbortError') {
    ...
  }
});

// when you want to abort
controller.abort();

works in edge 16 (2017-10-17), firefox 57 (2017-11-14), desktop safari 11.1 (2018-03-29), ios safari 11.4 (2018-03-29), chrome 67 (2018-05-29), and later.

on older browsers, you can use github's whatwg-fetch polyfill and AbortController polyfill. you can detect older browsers and use the polyfills conditionally, too:

import 'abortcontroller-polyfill/dist/abortcontroller-polyfill-only'
import {fetch} from 'whatwg-fetch'

// use native browser implementation if it supports aborting
const abortableFetch = ('signal' in new Request('')) ? window.fetch : fetch

Yes. You need to prefix the table name with "#" (hash) to create temporary tables.

If you do NOT need the table later, go ahead & create it. Temporary Tables are very much like normal tables. However, it gets created in tempdb. Also, it is only accessible via the current session i.e. For EG: if another user tries to access the temp table created by you, he'll not be able to do so.

"##" (double-hash creates "Global" temp table that can be accessed by other sessions as well.

Refer the below link for the Basics of Temporary Tables: http://www.codeproject.com/Articles/42553/Quick-Overview-Temporary-Tables-in-SQL-Server-2005

If the content of your table is less than 5000 rows & does NOT contain data types such as nvarchar(MAX), varbinary(MAX), consider using Table Variables.

They are the fastest as they are just like any other variables which are stored in the RAM. They are stored in tempdb as well, not in RAM.

DECLARE @ItemBack1 TABLE
(
 column1 int,
 column2 int,
 someInt int,
 someVarChar nvarchar(50)
);

INSERT INTO @ItemBack1
SELECT column1, 
       column2, 
       someInt, 
       someVarChar 
  FROM table2
 WHERE table2.ID = 7;

I had my Apache service not start same as MySQL one. Please follow these steps if none of above tips works :

1. Open regedit.exe on any windows this available . Run as administrator. (Only on windows 7 and later editions )
   2. Go to local machine/system/controlset001/services
   3. Find and delete folders of services apache and mysql .
   4. Uninstall xampp . Delete folder of xampp.
   5. Restart computer and reinstall Xampp . After that your Xampp apache and Mysql should work.

Note: Ports 80 and 443 must be unused by any program. 
      If it is in use . Just edit ports. There is a lot of tutorials about that .

i find best for do it fast and simple

1. find ur item in list

   var d = Details.Where(x => x.ProductID == selectedProduct.ID).SingleOrDefault();
   

2. make clone from current

   OrderDetail dd = d;
   

3. Update ur clone

   dd.Quantity++;
   

4. find index in list

   int idx = Details.IndexOf(d);
   

5. remove founded item in (1)

     Details.Remove(d);
   

6. insert

    if (idx > -1)
         Details.Insert(idx, dd);
     else
         Details.Insert(Details.Count, dd);
   

Note that if you use more than 9 capture groups you have to use the syntax ${10}.

$10 or \10 or \{10} will not work.

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

Using jQuery data() to store data

I guess hiding elements doesn't work cross-browser(2012), I have'nt tested it myself.

The first and foremost step to diagnose is to check the Cassandra logs.

Find out the process and there will be hints in the command line parameters to tell you where the logs files are.

ps aux | grep cassandra

In my case, it was in default location /etc/cassandra/conf/cassandra.yaml (if you installed the yum package).

Make sure three things are configured and configured the same host/ip.

1. listen_address - you may leave it blank it will default to hostname/first IP binding with eth0 network card
2. rpc_address - this is optional, leave blank if you want it to be same as listen_address
3. seeds - this is a double quoted string of comma-separated list of IP addresses or hostnames. This was default to a hardcoded "127.0.0.1", changing it to the same as list_address and restart of Cassandra service made it work for me.

.str.get

This is the simplest to specify string methods

# Setup
df = pd.DataFrame({'A': ['xyz', 'abc', 'foobar'], 'B': [123, 456, 789]})
df

        A    B
0     xyz  123
1     abc  456
2  foobar  789

df.dtypes

A    object
B     int64
dtype: object

For string (read:object) type columns, use

df['C'] = df['A'].str[0]
# Similar to,
df['C'] = df['A'].str.get(0)

.str handles NaNs by returning NaN as the output.

For non-numeric columns, an .astype conversion is required beforehand, as shown in @Ed Chum's answer.

# Note that this won't work well if the data has NaNs. 
# It'll return lowercase "n"
df['D'] = df['B'].astype(str).str[0]

df
        A    B  C  D
0     xyz  123  x  1
1     abc  456  a  4
2  foobar  789  f  7

List Comprehension and Indexing

There is enough evidence to suggest a simple list comprehension will work well here and probably be faster.

# For string columns
df['C'] = [x[0] for x in df['A']]

# For numeric columns
df['D'] = [str(x)[0] for x in df['B']]

df
        A    B  C  D
0     xyz  123  x  1
1     abc  456  a  4
2  foobar  789  f  7

If your data has NaNs, then you will need to handle this appropriately with an if/else in the list comprehension,

df2 = pd.DataFrame({'A': ['xyz', np.nan, 'foobar'], 'B': [123, 456, np.nan]})
df2

        A      B
0     xyz  123.0
1     NaN  456.0
2  foobar    NaN

# For string columns
df2['C'] = [x[0] if isinstance(x, str) else np.nan for x in df2['A']]

# For numeric columns
df2['D'] = [str(x)[0] if pd.notna(x) else np.nan for x in df2['B']]

        A      B    C    D
0     xyz  123.0    x    1
1     NaN  456.0  NaN    4
2  foobar    NaN    f  NaN

Let's do some timeit tests on some larger data.

df_ = df.copy()
df = pd.concat([df_] * 5000, ignore_index=True) 

%timeit df.assign(C=df['A'].str[0])
%timeit df.assign(D=df['B'].astype(str).str[0])

%timeit df.assign(C=[x[0] for x in df['A']])
%timeit df.assign(D=[str(x)[0] for x in df['B']])

UPDATE

The bookmarklet hack below is broken due to XHR issues and API changes.

Thankfully Github now has "A Whole New Code Search" which does the job superbly.

Checkout this voodoo: Github code search userscript.

Follow the directions there, or if you hate bloating your browser with scripts and extensions, use my bookmarkified bundle of the userscript:

javascript:(function(){var s='https://raw.githubusercontent.com/skratchdot/github-enhancement-suite/master/build/github-enhancement-suite.user.js',t='text/javascript',d=document,n=navigator,e;(e=d.createElement('script')).src=s;e.type=t;d.getElementsByTagName('head')[0].appendChild(e)})();doIt('');void('');

Save the source above as the URL of a new bookmark. Browse to any Github repo, click the bookmark, and bam: in-page, ajaxified code search.

CAVEAT Github must index a repo before you can search it.

Abracadabra...

Here's a sample search from the annotated ECMAScript 5.1 specification repository:

I am using Retrofit 1.9 to obtain a XML.

public class ServicioConexionRetrofitXML {

    public static final String API_BASE_URL = new GestorPreferencias().getPreferencias().getHost();
    public static final long tiempoMaximoRespuestaSegundos = 60;
    public static final long tiempoMaximoLecturaSegundos = 100;
    public static final OkHttpClient clienteOkHttp = new OkHttpClient();


    private static RestAdapter.Builder builder = new RestAdapter.Builder().
            setEndpoint(API_BASE_URL).
            setClient(new OkClient(clienteOkHttp)).setConverter(new SimpleXMLConverter());


    public static <S> S createService(Class<S> serviceClass) {
        clienteOkHttp.setConnectTimeout(tiempoMaximoRespuestaSegundos, TimeUnit.SECONDS);
        clienteOkHttp.setReadTimeout(tiempoMaximoLecturaSegundos, TimeUnit.SECONDS);
        RestAdapter adapter = builder.build();
        return adapter.create(serviceClass);
    }

}

If you are using Retrofit 1.9.0 and okhttp 2.6.0, add to your Gradle file.

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:okhttp:2.6.0'
    // Librería de retrofit para XML converter (Simple) Se excluyen grupos para que no entre
    // en conflicto.
    compile('com.squareup.retrofit:converter-simplexml:1.9.0') {
        exclude group: 'xpp3', module: 'xpp3'
        exclude group: 'stax', module: 'stax-api'
        exclude group: 'stax', module: 'stax'
    }

Note: If you need to fetch a JSON, just remove from code above.

.setConverter(new SimpleXMLConverter())

You don't need to convert the original entry - you can use TEXT function in the concatenation formula, e.g. with date in A1 use a formula like this

="Today is "&TEXT(A1,"dd-mm-yyyy")

You can change the "dd-mm-yyyy" part as required

For Kotlin:

In your adapter, simply call

(context as Your_Activity_Name).yourMethod()

I tried this is working

ALTER DATABASE dbName SET MULTI_USER WITH ROLLBACK IMMEDIATE

You can either create a static method or use the other class as a member of your class calling the function in the constructor.

public class aClass {
      private SomeOtherClass oc;
      public class aClass( SomeOtherClass otherClass) {
         oc = otherClass;
      }

      public callOtherClassMethod() {
         oc.otherClassMethod();
       }
    }

Yes, it's generally bad to call virtual method in the constructor.

At this point, the objet may not be fully constructed yet, and the invariants expected by methods may not hold yet.

Most of the replies so far are wrong in one respect: you can declare variables after the case statement, but you can't initialize them:

case 1:
    int x; // Works
    int y = 0; // Error, initialization is skipped by case
    break;
case 2:
    ...

As previously mentioned, a nice way around this is to use braces to create a scope for your case.

Functions are not allowed to have side-effects such as altering table contents.

Stored Procedures are.

If a function called a stored procedure, the function would become able to have side-effects.

So, sorry, but no, you can't call a stored procedure from a function.

if you use ini_set on the fly then you will find here http://php.net/manual/en/ini.core.php the information that e.g. upload_max_filesize and post_max_size is not changeable on the fly (PHP_INI_PERDIR).

Only a php.ini, .htaccess or vhost config change seems to change these variables.

Change each 'foo' to 'bar', but ask for confirmation first.

There is no use of pointers in java so far. You can create an object from the class and use different classes which are linked with each other and use the functions of every class in main class.

Only suggestion is to access your resp_dict via .get() for a more graceful approach that will degrade well if the data isn't as expected.

resp_dict = json.loads(resp_str)
resp_dict.get('name') # will return None if 'name' doesn't exist

You could also add some logic to test for the key if you want as well.

if 'name' in resp_dict:
    resp_dict['name']
else:
    # do something else here.

For those using React, detecting a same-origin iframe load event is as simple as setting onLoad event listener on iframe element.

<iframe src={'path-to-iframe-source'} onLoad={this.loadListener} frameBorder={0} />

In general, I/O means Input or Output. Those methods throw the IOException whenever an input or output operation is failed or interpreted. Note that this won't be thrown for reading or writing to memory as Java will be handling it automatically.

Here are some cases which result in IOException.

• Reading from a closed inputstream
• Try to access a file on the Internet without a network connection

I'm not sure of your exact requirement but one possible solution to improve 'readability' is to store it as an array.

{
  "testCases" :
  {
    "case.1" :
    {
      "scenario" : "this the case 1.",
      "result" : ["this is a very long line which is not easily readble.",
                  "so i would like to write it in multiple lines.",
                  "but, i do NOT require any new lines in the output."]
    }
  }
}

}

The join in back again whenever required with

result.join(" ")

Go to 'c:/Windows/System32' and delete the java.exe, javaw.exe and javaws.exe there. See at Registry Key '...' has value '1.7', but '1.6' is required. Java 1.7 is Installed and the Registry is Pointing to it

I thought I would post another answer for people that might be looking for something similar.

In our build job we have cases where we would want the build to continue, but be marked as unstable. For ours it's relating to version numbers.

So, I wanted to set a condition on the build and set the build to unstable if that condition is met.

I used the Conditional step (single) option as a build step.

Then I used Execute system Groovy script as the build step that would run when that condition is met.

I used Groovy Command and set the script the following

import hudson.model.*

def build = Thread.currentThread().executable
build.@result = hudson.model.Result.UNSTABLE

return

That seems to work quite well.

I stumbled upon the solution here

http://tech.akom.net/archives/112-Marking-Jenkins-build-UNSTABLE-from-environment-inject-groovy-script.html

Use reduce() to traverse the dictionary:

from functools import reduce  # forward compatibility for Python 3
import operator

def getFromDict(dataDict, mapList):
    return reduce(operator.getitem, mapList, dataDict)

and reuse getFromDict to find the location to store the value for setInDict():

def setInDict(dataDict, mapList, value):
    getFromDict(dataDict, mapList[:-1])[mapList[-1]] = value

All but the last element in mapList is needed to find the 'parent' dictionary to add the value to, then use the last element to set the value to the right key.

Demo:

>>> getFromDict(dataDict, ["a", "r"])
1
>>> getFromDict(dataDict, ["b", "v", "y"])
2
>>> setInDict(dataDict, ["b", "v", "w"], 4)
>>> import pprint
>>> pprint.pprint(dataDict)
{'a': {'r': 1, 's': 2, 't': 3},
 'b': {'u': 1, 'v': {'w': 4, 'x': 1, 'y': 2, 'z': 3}, 'w': 3}}

Note that the Python PEP8 style guide prescribes snake_case names for functions. The above works equally well for lists or a mix of dictionaries and lists, so the names should really be get_by_path() and set_by_path():

from functools import reduce  # forward compatibility for Python 3
import operator

def get_by_path(root, items):
    """Access a nested object in root by item sequence."""
    return reduce(operator.getitem, items, root)

def set_by_path(root, items, value):
    """Set a value in a nested object in root by item sequence."""
    get_by_path(root, items[:-1])[items[-1]] = value

And for completion's sake, a function to delete a key:

def del_by_path(root, items):
    """Delete a key-value in a nested object in root by item sequence."""
    del get_by_path(root, items[:-1])[items[-1]]

I Faced same problem but it work for.I executed the Pod Install Command Before 3 Hour ago after that its updated what i want. You just need to Keep tracking the "Activity Monitor" You can see their "git remote https" or "Git" in disk tab. It will download around 330 Mb then it shows 1 GB and After some minutes it will starts installing. No need to Execute extra command.

Note : during downloading your MAC need to in continuously Active mode.If your system goes in sleep mode then CPU stop the process and you will get a error Like Add manually.

You're the victim of the classic deadlock. task.Wait() or task.Result is a blocking call in UI thread which causes the deadlock.

Don't block in the UI thread. Never do it. Just await it.

private async void Button_Click(object sender, RoutedEventArgs 
{
      var task = GetResponseAsync<MyObject>("my url");
      var items = await task;
}

Btw, why are you catching the WebException and throwing it back? It would be better if you simply don't catch it. Both are same.

Also I can see you're mixing the asynchronous code with synchronous code inside the GetResponse method. StreamReader.ReadToEnd is a blocking call --you should be using StreamReader.ReadToEndAsync.

Also use "Async" suffix to methods which returns a Task or asynchronous to follow the TAP("Task based Asynchronous Pattern") convention as Jon says.

Your method should look something like the following when you've addressed all the above concerns.

public static async Task<List<T>> GetResponseAsync<T>(string url)
{
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
    var response = (HttpWebResponse)await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null);

    Stream stream = response.GetResponseStream();
    StreamReader strReader = new StreamReader(stream);
    string text = await strReader.ReadToEndAsync();

    return JsonConvert.DeserializeObject<List<T>>(text);
}

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?

To get the list of fields for which there are multiple records, you can use..

select field1,field2,field3, count(*)
  from table_name
  group by field1,field2,field3
  having count(*) > 1

Check this link for more information on how to delete the rows.

http://support.microsoft.com/kb/139444

There should be a criterion for deciding how you define "first rows" before you use the approach in the link above. Based on that you'll need to use an order by clause and a sub query if needed. If you can post some sample data, it would really help.

I spotted half of the problem: I can't use the 'indexer' notation to objects (my_object[0]). Is there a way to bypass it?

No; an object literal, as the name implies, is an object, and not an array, so you cannot simply retrieve a property based on an index, since there is no specific order of their properties. The only way to retrieve their values is by using the specific name:

var someVar = options.filters.firstName; //Returns 'abc'

Or by iterating over them using the for ... in loop:

for(var p in options.filters) {
    var someVar = options.filters[p]; //Returns the property being iterated
}

The main difference between localStorage and sessionStorage is that sessionStorage is unique per tab. If you close the tab the sessionStorage gets deleted, localStorage does not. Also you cannot communicate between tabs :)

Another subtle difference is that for example on Safari (8.0.3) localStorage has a limit of 2551 k characters but sessionStorage has unlimited storage

On Chrome (v43) both localStorage and sessionStorage are limited to 5101 k characters (no difference between normal / incognito mode)

On Firefox both localStorage and sessionStorage are limited to 5120 k characters (no difference between normal / private mode )

No difference in speed whatsoever :)

There's also a problem with Mobile Safari and Mobile Chrome, Private Mode Safari & Chrome have a maximum space of 0KB

You will need to use reflection to get the type "TestRunner". Use the Assembly.GetType method.

class Program
{
    static void Main(string[] args)
    {
        Assembly assembly = Assembly.LoadFile(@"C:\dyn.dll");
        Type type = assembly.GetType("TestRunner");
        var obj = (TestRunner)Activator.CreateInstance(type);
        obj.Run();
    }
}

In random.random() the output lies between 0 & 1 , and it takes no input parameters

Whereas random.uniform() takes parameters , wherein you can submit the range of the random number. e.g.
import random as ra print ra.random() print ra.uniform(5,10)

OUTPUT:-
0.672485369423 7.9237539416

One possible solution might be to use the ng-cloak directive with the element where we are using the models e.g.

<div ng-cloak="">
  Value in  myModel is: {{myModel}}
</div>

I think this one takes least effort.

Very simple solution with one big constraint: you can't assign custom values to enum values, but with the right regex, you could. you could also add a map to translate them back to enum values without much more effort:

#include <vector>
#include <string>
#include <regex>
#include <iterator>

std::vector<std::string> split(const std::string& s, 
                               const std::regex& delim = std::regex(",\\s*"))
{
    using namespace std;
    vector<string> cont;
    copy(regex_token_iterator<string::const_iterator>(s.begin(), s.end(), delim, -1), 
         regex_token_iterator<string::const_iterator>(),
         back_inserter(cont));
    return cont;
}

#define EnumType(Type, ...)     enum class Type { __VA_ARGS__ }

#define EnumStrings(Type, ...)  static const std::vector<std::string> \
                                Type##Strings = split(#__VA_ARGS__);

#define EnumToString(Type, ...) EnumType(Type, __VA_ARGS__); \
                                EnumStrings(Type, __VA_ARGS__)

Usage example:

EnumToString(MyEnum, Red, Green, Blue);

In my case I'm using C# OracleCommand with OracleParameter, and I set all the the parameters Size property to max length of each column, then the error solved.

OracleParameter parm1 = new OracleParameter();
param1.OracleDbType = OracleDbType.Varchar2;
param1.Value = "test1";
param1.Size = 8;

OracleParameter parm2 = new OracleParameter();
param2.OracleDbType = OracleDbType.Varchar2;
param2.Value = "test1";
param2.Size = 12;

If you installed the command line tools separately, delete them using:

sudo rm -rf /Library/Developer/CommandLineTools

I made an extension function for Kotlin. Paste it where ever you like and import it while creating OkHttpClient.

fun OkHttpClient.Builder.ignoreAllSSLErrors(): OkHttpClient.Builder {
    val naiveTrustManager = object : X509TrustManager {
        override fun getAcceptedIssuers(): Array<X509Certificate> = arrayOf()
        override fun checkClientTrusted(certs: Array<X509Certificate>, authType: String) = Unit
        override fun checkServerTrusted(certs: Array<X509Certificate>, authType: String) = Unit
    }

    val insecureSocketFactory = SSLContext.getInstance("TLSv1.2").apply {
        val trustAllCerts = arrayOf<TrustManager>(naiveTrustManager)
        init(null, trustAllCerts, SecureRandom())
    }.socketFactory

    sslSocketFactory(insecureSocketFactory, naiveTrustManager)
    hostnameVerifier(HostnameVerifier { _, _ -> true })
    return this
}

use it like this:

val okHttpClient = OkHttpClient.Builder().apply {
    // ...
    if (BuildConfig.DEBUG) //if it is a debug build ignore ssl errors
        ignoreAllSSLErrors()
    //...
}.build()

For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png, and I put this in my css file...

div.example { background: url('example.png'); }

... then somehow it magically works. I figured this out by running the rake assets:precompile task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets. That's ironic, IMO...

In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.

Kind of frustrating there aren't better docs out there for this big of a change.

Our team considers date-fns the best library in this space. It treats dates as immutable (Moment.js will probably never adopt immutability), it's faster, and can be loaded modularly.

const newDate = DateFns.addDays(oldDate, 2);

I know it's too late. But I found a solution even if you are using overflow or display:flex in parent elements sticky will work.

steps:

1. Create a parent element for the element you want to set sticky (Get sure that the created element is relative to body or to full-width & full-height parent).

2. Add the following styles to the parent element:

   { position: absolute; height: 100vmax; }

3. For the sticky element, get sure to add z-index that is higher than all elements in the page.

That's it! Now it must work. Regards

I'm surprised no one posted this simple solution. That is if your strings are going to be "true" or "false".

def to_boolean(str)
    eval(str)
end

I've had to face this issue and also tried to solve it from different perspectives. Finally I found a solution by using a single flag to check if an error happened.

... extends WebViewClient {

    boolean error;

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {

        showLoading(true);
        super.onPageStarted(view, url, favicon);

        error  = false; // IMPORTANT
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);

        if(!error) {
            Observable.timer(100, TimeUnit.MICROSECONDS, AndroidSchedulers.mainThread())
                    .subscribe((data) -> view.setVisibility(View.VISIBLE) );
        }

        showLoading(false);
    }


    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

        view.stopLoading();

        view.setVisibility(View.INVISIBLE) 
        error  = true;  

        // Handle the error
    }


     @Override
    @TargetApi(android.os.Build.VERSION_CODES.M)
    public void onReceivedError(WebView view,
                                WebResourceRequest request,
                                WebResourceError error) {

        this.onReceivedError(view, error.getErrorCode(),
                error.getDescription().toString(),
                request.getUrl().toString());
    }
 }

This way I hide the page every time there's an error and show it when the page has loaded again properly.

Also added a small delay in case.

I avoided the solution of loading an empty page as it does not allow you to do webview.reload() later on due to it adds that new page in the navigation history.

You can add float:none; margin:auto; styling to centerize column content.

To avoid any ambiguity, use the utilities methods from SwingUtilities :

SwingUtilities.isLeftMouseButton(MouseEvent anEvent) SwingUtilities.isRightMouseButton(MouseEvent anEvent) SwingUtilities.isMiddleMouseButton(MouseEvent anEvent)

Answering to myself. From the RequireJS website:

//THIS WILL FAIL
define(['require'], function (require) {
    var namedModule = require('name');
});

This fails because requirejs needs to be sure to load and execute all dependencies before calling the factory function above. [...] So, either do not pass in the dependency array, or if using the dependency array, list all the dependencies in it.

My solution:

// Modules configuration (modules that will be used as Jade helpers)
define(function () {
    return {
        'moment':   'path/to/moment',
        'filesize': 'path/to/filesize',
        '_':        'path/to/lodash',
        '_s':       'path/to/underscore.string'
    };
});

The loader:

define(['jade', 'lodash', 'config'], function (Jade, _, Config) {
    var deps;

    // Dynamic require
    require(_.values(Config), function () {
        deps = _.object(_.keys(Config), arguments);

        // Use deps...
    });
});

A particular feature of a HashMap is that unlike, say, balanced trees, its behavior is probabilistic. In these cases its usually most helpful to talk about complexity in terms of the probability of a worst-case event occurring would be. For a hash map, that of course is the case of a collision with respect to how full the map happens to be. A collision is pretty easy to estimate.

p_collision = n / capacity

So a hash map with even a modest number of elements is pretty likely to experience at least one collision. Big O notation allows us to do something more compelling. Observe that for any arbitrary, fixed constant k.

O(n) = O(k * n)

We can use this feature to improve the performance of the hash map. We could instead think about the probability of at most 2 collisions.

p_{collision x 2} = (n / capacity)²

This is much lower. Since the cost of handling one extra collision is irrelevant to Big O performance, we've found a way to improve performance without actually changing the algorithm! We can generalzie this to

p_{collision x k} = (n / capacity)^k

And now we can disregard some arbitrary number of collisions and end up with vanishingly tiny likelihood of more collisions than we are accounting for. You could get the probability to an arbitrarily tiny level by choosing the correct k, all without altering the actual implementation of the algorithm.

We talk about this by saying that the hash-map has O(1) access with high probability

if you want to add a global property, you can use:

    var styleEl = document.createElement('style'), styleSheet;
            document.head.appendChild(styleEl);
            styleSheet = styleEl.sheet;
            styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);

From Wikipedia Media type,

A media type is composed of a type, a subtype, and optional parameters. As an example, an HTML file might be designated text/html; charset=UTF-8.

Media type consists of top-level type name and sub-type name, which is further structured into so-called "trees".

top-level type name / subtype name [ ; parameters ]

top-level type name / [ tree. ] subtype name [ +suffix ] [ ; parameters ]

All media types should be registered using the IANA registration procedures. Currently the following trees are created: standard, vendor, personal or vanity, unregistered x.

Standard:

Media types in the standards tree do not use any tree facet (prefix).

type / media type name [+suffix]

Examples: "application/xhtml+xml", "image/png"

Vendor:

Vendor tree is used for media types associated with publicly available products. It uses vnd. facet.

type / vnd. media type name [+suffix] - used in the case of well-known producer

type / vnd. producer's name followed by media type name [+suffix] - producer's name must be approved by IANA

type / vnd. producer's name followed by product's name [+suffix] - producer's name must be approved by IANA

Personal or Vanity tree:

Personal or Vanity tree includes media types created experimentally or as part of products that are not distributed commercially. It uses prs. facet.

type / prs. media type name [+suffix]

Unregistered x. tree:

The "x." tree may be used for media types intended exclusively for use in private, local environments and only with the active agreement of the parties exchanging them. Types in this tree cannot be registered.

According to the previous version of RFC 6838 - obsoleted RFC 2048 (published in November 1996) it should rarely, if ever, be necessary to use unregistered experimental types, and as such use of both "x-" and "x." forms is discouraged. Previous versions of that RFC - RFC 1590 and RFC 1521 stated that the use of "x-" notation for the sub-type name may be used for unregistered and private sub-types, but this recommendation was obsoleted in November 1996.

type / x. media type name [+suffix]

So its clear that the standard type MIME type application/pdf is the appropriate one to use while you should avoid using the obsolete and unregistered x- media type as stated in RFC 2048 and RFC 6838.

The reason to make an App with no activity or service could be making a Homescreen Widget app that doesn't need to be started.
Once you start a project don't create any activities. After you created the project just hit run. Android studio will say No default activity found.

Click Edit Configuration (From the Run menu) and in the Launch option part set the Launch value to Nothing. Then click ok and run the App.

(Since there is no launcher activity, No app will be show in the Apps menu.).

API keys are just one way of authenticating users of web services.

From ISO14882:2011(e) 5.6-4:

The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined. For integral operands the / operator yields the algebraic quotient with any fractional part discarded; if the quotient a/b is representable in the type of the result, (a/b)*b + a%b is equal to a.

The rest is basic math:

(-7/3) => -2
-2 * 3 => -6
so a%b => -1

(7/-3) => -2
-2 * -3 => 6
so a%b => 1

Note that

If both operands are nonnegative then the remainder is nonnegative; if not, the sign of the remainder is implementation-defined.

from ISO14882:2003(e) is no longer present in ISO14882:2011(e)

This is issue has almost driven me nut in the past. To buttress what others have said, after making sure that all the indentations on the yaml file has been corrected and the problem persist, run a 'flutter clean' command at the terminal in Android studio. As at flutter 1.9, this should fix the issue.

my solution:

create a file card_view_border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/white_background"/>
<stroke android:width="2dp" 
    android:color="@color/red" />
<corners android:radius="20dip"/>
</shape>

and set programmatically

cardView.setBackgroundResource(R.drawable.card_view_border);

Base64 instead of escaping special characters

I'll give you a very different but real example: I write javascript code to be run in a browser. HTML tags have ID values, but there are constraints on what characters are valid in an ID.

But I want my ID to losslessly refer to files in my file system. Files in reality can have all manner of weird and wonderful characters in them from exclamation marks, accented characters, tilde, even emoji! I cannot do this:

<div id="/path/to/my_strangely_named_file!@().jpg">
    <img src="http://myserver.com/path/to/my_strangely_named_file!@().jpg">
    Here's a pic I took in Moscow.
</div>

Suppose I want to run some code like this:

# ERROR
document.getElementById("/path/to/my_strangely_named_file!@().jpg");

I think this code will fail when executed.

With Base64 I can refer to something complicated without worrying about which language allows what special characters and which need escaping:

document.getElementById("18GerPD8fY4iTbNpC9hHNXNHyrDMampPLA");

Unlike using an MD5 or some other hashing function, you can reverse the encoding to find out what exactly the data was that actually useful.

I wish I knew about Base64 years ago. I would have avoided tearing my hair out with ‘encodeURIComponent’ and str.replace(‘\n’,’\\n’)

SSH transfer of text:

If you're trying to pass complex data over ssh (e.g. a dotfile so you can get your shell personalizations), good luck doing it without Base 64. This is how you would do it with base 64 (I know you can use SCP, but that would take multiple commands - which complicates key bindings for sshing into a server):

I'm surprised not a lot of people know about the download attribute for a elements. Please help spread the word about it! You can have a hidden html link, and fake a click on it. If the html link has the download attribute it downloads the file, not views it, no matter what. Here's the code. It will download a cat picture if it can find it.

document.getElementById('download').click();

<a href="https://docs.google.com/uc?id=0B0jH18Lft7ypSmRjdWg1c082Y2M" download id="download" hidden></a>

Note: This is not supported on all browsers: http://www.w3schools.com/tags/att_a_download.asp

Run This Command

npm install bootstrap@3

your Angular.json

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.min.css",
  "src/styles.css"
],

Instead of trying to manually align the text into columns with arbitrary strings of spaces, you should embed actual tabs (the \t escape sequence) into each output string:

Console.WriteLine("Customer name" + "\t"
    + "sales" + "\t" 
    + "fee to be paid" + "\t" 
    + "70% value" + "\t" 
    + "30% value");
for (int DisplayPos = 0; DisplayPos < LineNum; DisplayPos++)
{
    seventy_percent_value = ((fee_payable[DisplayPos] / 10.0) * 7);
    thirty_percent_value = ((fee_payable[DisplayPos] / 10.0) * 3);          
    Console.WriteLine(customer[DisplayPos] + "\t" 
        + sales_figures[DisplayPos] + "\t" 
        + fee_payable + "\t\t"
        + seventy_percent_value + "\t\t" 
        + thirty_percent_value);
}

This might help:

If the adb connection is ever lost:

Make sure that your host is still connected to the same Wi-Fi network your Android device is. Reconnect by executing the "adb connect IP" step. (IP is obviously different when you change location.) Or if that doesn't work, reset your adb host: adb kill-server and then start over from the beginning.

@(new HtmlString(myString))

That's really an informational message.

Likely, you're doing OPTIMIZE on an InnoDB table (table using the InnoDB storage engine, rather than the MyISAM storage engine).

InnoDB doesn't support the OPTIMIZE the way MyISAM does. It does something different. It creates an empty table, and copies all of the rows from the existing table into it, and essentially deletes the old table and renames the new table, and then runs an ANALYZE to gather statistics. That's the closest that InnoDB can get to doing an OPTIMIZE.

The message you are getting is basically MySQL server repeating what the InnoDB storage engine told MySQL server:

Table does not support optimize is the InnoDB storage engine saying...

"I (the InnoDB storage engine) don't do an OPTIMIZE operation like my friend (the MyISAM storage engine) does."

"doing recreate + analyze instead" is the InnoDB storage engine saying...

"I have decided to perform a different set of operations which will achieve an equivalent result."

I have done this:

#!/usr/bin/env python3

import fileinput
import os

Dir = input ("Source directory: ")
os.chdir(Dir)

Filelist = os.listdir()
print('File list: ',Filelist)

NomeFile = input ("Insert file name: ")

CarOr = input ("Text to search: ")

CarNew = input ("New text: ")

with fileinput.FileInput(NomeFile, inplace=True, backup='.bak') as file:
    for line in file:
        print(line.replace(CarOr, CarNew), end='')

file.close ()

You can use numpy.shape.

import numpy as np
x = np.array([[1, 2],[3, 4],[5, 6]])

Result:

>>> x
array([[1, 2],
       [3, 4],
       [5, 6]])
>>> np.shape(x)
(3, 2)

First value in the tuple is number rows = 3; second value in the tuple is number of columns = 2.

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

the solution what I found to work in my case

$('#multiselect1').multiselect({
    selectAllValue: 'multiselect-all',
    enableCaseInsensitiveFiltering: true,
    enableFiltering: true,
    maxHeight: '300',
    buttonWidth: '235',
    onChange: function(element, checked) {
        var brands = $('#multiselect1 option:selected');
        var selected = [];
        $(brands).each(function(index, brand){
            selected.push([$(this).val()]);
        });

        console.log(selected);
    }
}); 

Legacy. List was originally defined to be functional-languages-looking:

1 :: 2 :: Nil // a list
list1 ::: list2  // concatenation of two lists

list match {
  case head :: tail => "non-empty"
  case Nil          => "empty"
}

Of course, Scala evolved other collections, in an ad-hoc manner. When 2.8 came out, the collections were redesigned for maximum code reuse and consistent API, so that you can use ++ to concatenate any two collections -- and even iterators. List, however, got to keep its original operators, aside from one or two which got deprecated.

@ - Instance variable of a class
@@ - Class variable, also called as static variable in some cases

A class variable is a variable that is shared amongst all instances of a class. This means that only one variable value exists for all objects instantiated from this class. If one object instance changes the value of the variable, that new value will essentially change for all other object instances.

Another way of thinking of thinking of class variables is as global variables within the context of a single class. Class variables are declared by prefixing the variable name with two @ characters (@@). Class variables must be initialized at creation time

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

If you want to exclude the sub-directories, you can use

git diff <ref1>..<ref2> -- $(git diff <ref1>..<ref2> --name-only | grep -v /)

clear site data in your browser. and it will be fixed. sometimes when you run proxies, vpns or some other programs this error happens.

Strings:

>>> n = '4'
>>> print(n.zfill(3))
004

And for numbers:

>>> n = 4
>>> print(f'{n:03}') # Preferred method, python >= 3.6
004
>>> print('%03d' % n)
004
>>> print(format(n, '03')) # python >= 2.6
004
>>> print('{0:03d}'.format(n))  # python >= 2.6 + python 3

>>> print('{foo:03d}'.format(foo=n))  # python >= 2.6 + python 3
004
>>> print('{:03d}'.format(n))  # python >= 2.7 + python3
004

String formatting documentation.

<input type="text" autoFocus />

always try the simple and basic solution first, works for me.

I would say to add a paragraph with a period in it and style it like so:

<p class="center">.</p>

<style>
.center {font-size: 0px; margin-bottom: anyPercentage%;}
</style>

You may need to toy around with the percentages to get it right

Which programming language are you using? May be you just need to escape the backslash like "[^\\s-]"

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

Using update directly is more efficient and could also prevent integrity problems.

From the official documentation https://docs.djangoproject.com/en/3.0/ref/models/querysets/#django.db.models.query.QuerySet.update

If you’re just updating a record and don’t need to do anything with the model object, the most efficient approach is to call update(), rather than loading the model object into memory. For example, instead of doing this:

e = Entry.objects.get(id=10)
e.comments_on = False
e.save()

…do this:

Entry.objects.filter(id=10).update(comments_on=False)

Using update() also prevents a race condition wherein something might change in your database in the short period of time between loading the object and calling save().

with UnionTable as  
(
    SELECT a.id, a.time FROM dbo.a
    UNION
    SELECT b.id, b.time FROM dbo.b
) SELECT id FROM UnionTable GROUP BY id

const char* one = "one";
const char* two = "two";
char result[40];
sprintf(result, "%s%s", one, two);

I think this is a esay solution for this. Make Previous button type to button, and a new add onclick attribute in button with value jQuery(this).attr('type','submit');.

So, when the user clicks on the Previous button then its type will be changed to submit and the form will be submitted with Previous button.

<form>
  <!-- Put your cursor in this field and press Enter -->
  <input type="text" name="field1" />

  <!-- This is the button that will submit -->
  <input type="button" onclick="jQuery(this).attr('type','submit');" name="prev" value="Previous Page" />

  <!-- But this is the button that I WANT to submit -->
  <input type="submit" name="next" value="Next Page" />
</form>

I shared my experience of using two LEFT JOINS in a single SQL query.

I have 3 tables:

Table 1) Patient consists columns PatientID, PatientName

Table 2) Appointment consists columns AppointmentID, AppointmentDateTime, PatientID, DoctorID

Table 3) Doctor consists columns DoctorID, DoctorName

Query:

SELECT Patient.patientname, AppointmentDateTime, Doctor.doctorname

FROM Appointment 

LEFT JOIN Doctor ON Appointment.doctorid = Doctor.doctorId  //have doctorId column common

LEFT JOIN Patient ON Appointment.PatientId = Patient.PatientId      //have patientid column common

WHERE Doctor.Doctorname LIKE 'varun%' // setting doctor name by using LIKE

AND Appointment.AppointmentDateTime BETWEEN '1/16/2001' AND '9/9/2014' //comparison b/w dates 

ORDER BY AppointmentDateTime ASC;  // getting data as ascending order

I wrote the solution to get date format like "mm/dd/yy" (under my name "VARUN TEJ REDDY")

bitvise tunnelier works really well

I was able to achieve the desired result by using Alt + Shift + up/down and then typing the desired comment characters and additional character.

You can use FusedLocationProvider

For using Fused Location Provider in your project you will have to add the google play services location dependency in our app level build.gradle file

dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   ...
   ...
   ...
   implementation 'com.google.android.gms:play-services-location:17.0.0'
}

Permissions in Manifest

Apps that use location services must request location permissions. Android offers two location permissions: ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

As you may know that from Android 6.0 (Marshmallow) you must request permissions for important access in the runtime. Cause it’s a security issue where while installing an application, user may not clearly understand about an important permission of their device.

ActivityCompat.requestPermissions(
    this,
    arrayOf(Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION),
    PERMISSION_ID
)

Then you can use the FusedLocationProvider Client to get the updated location in your desired place.

    mFusedLocationClient.lastLocation.addOnCompleteListener(this) { task ->
        var location: Location? = task.result
        if (location == null) {
            requestNewLocationData()
        } else {
            findViewById<TextView>(R.id.latTextView).text = location.latitude.toString()
            findViewById<TextView>(R.id.lonTextView).text = location.longitude.toString()
        }
    }

You can also check certain configuration like if the device has location settings on or not. You can also check the article on Detect Current Latitude & Longitude using Kotlin in Android for more functionality. If there is no cache location then it will catch the current location using:

private fun requestNewLocationData() {
    var mLocationRequest = LocationRequest()
    mLocationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    mLocationRequest.interval = 0
    mLocationRequest.fastestInterval = 0
    mLocationRequest.numUpdates = 1

    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
    mFusedLocationClient!!.requestLocationUpdates(
            mLocationRequest, mLocationCallback,
            Looper.myLooper()
    )
}

I found I had the same error. I was compiling a code with both lapack and blas. When I switched the order that the two libraries were called the error went away.

"LAPACK_LIB = -llapack -lblas" worked where "LAPACK_LIB = -lblas -llapack" gave the error described above.

I use

setTranscriptMode(ListView.TRANSCRIPT_MODE_NORMAL);

to add entries at the bottom, and older entries scroll off the top, like a chat transcript

You can place the image in a div and add a div id and have the CSS for that div have a text-align:center:

HTML:

<div id="intro_img">

    <img src="???" alt="???">

</div>

CSS:

#intro_img {
    text-align: center;
}

I've done this kind of thing with a form that contains a TextBox.

So if you wanted to put this in say cell H1, then use:

ActiveSheet.Range("H1").Value = txtBoxName.Text

You can directly access a global variable inside a function. If you want to change the value of that global variable, use "global variable_name". See the following example:

var = 1
def global_var_change():
      global var
      var = "value changed"
global_var_change() #call the function for changes
print var

Generally speaking, this is not a good programming practice. By breaking namespace logic, code can become difficult to understand and debug.

Logging to stdout and rotating file with different levels and formats:

import logging
import logging.handlers
import sys

if __name__ == "__main__":

    # Change root logger level from WARNING (default) to NOTSET in order for all messages to be delegated.
    logging.getLogger().setLevel(logging.NOTSET)

    # Add stdout handler, with level INFO
    console = logging.StreamHandler(sys.stdout)
    console.setLevel(logging.INFO)
    formater = logging.Formatter('%(name)-13s: %(levelname)-8s %(message)s')
    console.setFormatter(formater)
    logging.getLogger().addHandler(console)

    # Add file rotating handler, with level DEBUG
    rotatingHandler = logging.handlers.RotatingFileHandler(filename='rotating.log', maxBytes=1000, backupCount=5)
    rotatingHandler.setLevel(logging.DEBUG)
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    rotatingHandler.setFormatter(formatter)
    logging.getLogger().addHandler(rotatingHandler)

    log = logging.getLogger("app." + __name__)

    log.debug('Debug message, should only appear in the file.')
    log.info('Info message, should appear in file and stdout.')
    log.warning('Warning message, should appear in file and stdout.')
    log.error('Error message, should appear in file and stdout.')

I think you ought to use a regex:

import java.util.regex.*;

public class Test {
  public static void main(String[] args) {
    String neg = "-123abc";
    String pos = "123abc";
    String non = "abc123";
        /* I'm not sure if this regex is too verbose, but it should be
         * clear. It checks that the string starts with either a series
         * of one or more digits... OR a negative sign followed by 1 or
         * more digits. Anything can follow the digits. Update as you need
         * for things that should not follow the digits or for floating
         * point numbers.
         */
    Pattern pattern = Pattern.compile("^(\\d+.*|-\\d+.*)");
    Matcher matcher = pattern.matcher(neg);
    if(matcher.matches()) {
        System.out.println("matches negative number");
    }
    matcher = pattern.matcher(pos);
    if (matcher.matches()) {
        System.out.println("positive matches");
    }
    matcher = pattern.matcher(non);
    if (!matcher.matches()) {
        System.out.println("letters don't match :-)!!!");
    }
  }
}

You may want to adjust this to accept floating point numbers, but this will work for negatives. Other answers won't work for negatives because they only check the first character! Be more specific about your needs and I can help you adjust this approach.

There is a jQuery solution in this thread. Try something like this:

var decoded = $("<div/>").html('your string').text();

This sets the innerHTML of a new <div> element (not appended to the page), causing jQuery to decode it into HTML, which is then pulled back out with .text().

How about Azure ServiceBus? It supports nodejs.

The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.

If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.

$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');

Using Java.util.ArrayList or LinkedList is the usual way of doing this. With arrays that's not possible as I know.

Example:

List<Float> unindexedVectors = new ArrayList<Float>();

unindexedVectors.add(2.22f);

unindexedVectors.get(2);

Your code should work, but you can also try:

    if not item in mylist :

You can disable caching globally using $.ajaxSetup(), for example:

$.ajaxSetup({ cache: false });

This appends a timestamp to the querystring when making the request. To turn cache off for a particular $.ajax() call, set cache: false on it locally, like this:

$.ajax({
  cache: false,
  //other options...
});

I would do it in the simplest way, so anyone can understand what happens, even if there are smarter ways:

my $text = "";
while (my $line = <FILE>) {
    $text .= $line;
}

Not using iframes puts you in a world of handling #document security issues with cross domain and links firing unexpected ways that was not intended for originally, do you really need bad Advertisements?

You can use jquery .load function to send the page to whatever html element you want to target, assuming your not getting this from another domain.

You can use javascript .innerHTML value to set and to rewrite the element with whatever you want, but if you add another file you might be writing against 2 documents in 1... like a in another

iframes are old, another way we can add "src" into the html alone without any use for javascript. But it's old, prehistoric, and just plain OLD! Frameset makes it worse because I can put #document in those to handle multiple html files. An Old way people created navigation menu's Long and before people had FLIP phones.

1.) Yes you will have to work in Javascript if you do NOT want to use an Iframe.

2.) There is a good hack in which you can set the domain to equal each other without having to set server stuff around. Means you will have to have edit capabilities of the documents.

3.) javascript window.document is limited to the iframe itself and can NOT go above the iframe if you want to grab something through the DOM itself. Because it treats it like a separate tab, it also defines it in another document object model.

Why does nobody here consider using this simple code?

TCHAR szDir[MAX_PATH] = { 0 };

GetModuleFileName(NULL, szDir, MAX_PATH);
szDir[std::string(szDir).find_last_of("\\/")] = 0;

or even simpler

TCHAR szDir[MAX_PATH] = { 0 };
TCHAR* szEnd = nullptr;
GetModuleFileName(NULL, szDir, MAX_PATH);
szEnd = _tcsrchr(szDir, '\\');
*szEnd = 0;

Old Question, but for angular 6, this needs to be done when you are using HttpClient I am exposing token data publicly here but it would be good if accessed via read-only properties.

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable, of } from 'rxjs';
import { delay, tap } from 'rxjs/operators';
import { Router } from '@angular/router';


@Injectable()
export class AuthService {
    isLoggedIn: boolean = false;
    url = "token";

    tokenData = {};
    username = "";
    AccessToken = "";

    constructor(private http: HttpClient, private router: Router) { }

    login(username: string, password: string): Observable<object> {
        let model = "username=" + username + "&password=" + password + "&grant_type=" + "password";

        return this.http.post(this.url, model).pipe(
            tap(
                data => {
                    console.log('Log In succesful')
                    //console.log(response);
                    this.isLoggedIn = true;
                    this.tokenData = data;
                    this.username = data["username"];
                    this.AccessToken = data["access_token"];
                    console.log(this.tokenData);
                    return true;

                },
                error => {
                    console.log(error);
                    return false;

                }
            )
        );
    }
}

replace Range("A1") = "Asdf" with Range("A1").value = "Asdf"

As with most things you should pick which to use based on the context and what is conceptually the correct way to go. A switch is really saying "pick one of these based on this variables value" but an if statement is just a series of boolean checks.

As an example, if you were doing:

int value = // some value
if (value == 1) {
    doThis();
} else if (value == 2) {
    doThat();
} else {
    doTheOther();
}

This would be much better represented as a switch as it then makes it immediately obviously that the choice of action is occurring based on the value of "value" and not some arbitrary test.

Also, if you find yourself writing switches and if-elses and using an OO language you should be considering getting rid of them and using polymorphism to achieve the same result if possible.

Finally, regarding switch taking longer to type, I can't remember who said it but I did once read someone ask "is your typing speed really the thing that affects how quickly you code?" (paraphrased)

Instead of invoking the sp_helptext locally with a remote argument, invoke it remotely with a local argument:

Don't use Holo theme and the Actionbar will disappear. This code is working for me on API 8+, with support lib v7:

<style name="NoActionBar" parent="@style/Theme.AppCompat.Light">
<item name="android:windowNoTitle">true</item>
</style>

set that theme for your activity:

<activity android:theme="@style/NoActionBar" ... />

and in your activity class.

It works even when it extends ActionBarActivity.

For me the basic oracle only was not installed. Please ensure you have oracle installed and then try checking host and port.

extension UIColor {
    public convenience init?(hex: String) {
        let r, g, b, a: CGFloat

        if hex.hasPrefix("#") {
            let start = hex.index(hex.startIndex, offsetBy: 1)
            let hexColor = String(hex[start...])

            if hexColor.count == 8 {
                let scanner = Scanner(string: hexColor)
                var hexNumber: UInt64 = 0

                if scanner.scanHexInt64(&hexNumber) {
                    r = CGFloat((hexNumber & 0xff000000) >> 24) / 255
                    g = CGFloat((hexNumber & 0x00ff0000) >> 16) / 255
                    b = CGFloat((hexNumber & 0x0000ff00) >> 8) / 255
                    a = CGFloat(hexNumber & 0x000000ff) / 255

                    self.init(red: r, green: g, blue: b, alpha: a)
                    return
                }
            }
        }

        return nil
    }
}

Usage:

let white = UIColor(hex: "#ffffff")

You can't use transparency on background-images directly, but you can achieve this effect with something like this:

It is not possible to use the RTMP protocol in HTML 5, because the RTMP protocol is only used between the server and the flash player. So you can use the other streaming protocols for viewing the streaming videos in HTML 5.

$('#frmTest input:checked').length > 0

Get the value for an associative array property when the property name is an integer:

Starting with an associative array where the property names are integers:

var categories = [
    {"1": "Category 1"},
    {"2": "Category 2"},
    {"3": "Category 3"},
    {"4": "Category 4"}
];

Push items to the array:

categories.push({"2300": "Category 2300"});
categories.push({"2301": "Category 2301"});

Loop through the array and do something with the property value.

for (var i = 0; i < categories.length; i++) {
    for (var categoryid in categories[i]) {
        var category = categories[i][categoryid];
        // Log progress to the console
        console.log(categoryid + ": " + category);
        //  ... do something
    }
}

Console output should look like this:

1: Category 1
2: Category 2
3: Category 3
4: Category 4
2300: Category 2300
2301: Category 2301

As you can see, you can get around the associative array limitation and have a property name be an integer.

NOTE: The associative array in my example is the JSON content you would have if you serialized a Dictionary<string, string>[] object.

AppSettings.Set does not persist the changes to your configuration file. It just changes it in memory. If you put a breakpoint on System.Configuration.ConfigurationManager.AppSettings.Set("lang", lang);, and add a watch for System.Configuration.ConfigurationManager.AppSettings[0] you will see it change from "English" to "Russian" when that line of code runs.

The following code (used in a console application) will persist the change.

class Program
{
    static void Main(string[] args)
    {
        UpdateSetting("lang", "Russian");
    }

    private static void UpdateSetting(string key, string value)
    {
        Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        configuration.AppSettings.Settings[key].Value = value;
        configuration.Save();

        ConfigurationManager.RefreshSection("appSettings");
    }
}

From this post: http://vbcity.com/forums/t/152772.aspx

One major point to note with the above is that if you are running this from the debugger (within Visual Studio) then the app.config file will be overwritten each time you build. The best way to test this is to build your application and then navigate to the output directory and launch your executable from there. Within the output directory you will also find a file named YourApplicationName.exe.config which is your configuration file. Open this in Notepad to see that the changes have in fact been saved.

 datetime.datetime.now() - datetime.timedelta(minutes=15)

I have the same problem, and I have add this code to my application and its work fine for me.

step -1 : added the jquery.placeholder.js plugin

step -2 :write the below code in your area.

$(function () {
       $('input, textarea').placeholder();
});

And now I can see placeholders on the input boxes!

STA (Single Threaded Apartment) is basically the concept that only one thread will interact with your code at a time. Calls into your apartment are marshaled via windows messages (using a non-visible) window. This allows calls to be queued and wait for operations to complete.

MTA (Multi Threaded Apartment) is where many threads can all operate at the same time and the onus is on you as the developer to handle the thread security.

There is a lot more to learn about threading models in COM, but if you are having trouble understanding what they are then I would say that understanding what the STA is and how it works would be the best starting place because most COM objects are STA’s.

Apartment Threads, if a thread lives in the same apartment as the object it is using then it is an apartment thread. I think this is only a COM concept because it is only a way of talking about the objects and threads they interact with…

You sure can do this!

//make a regular expression out of your needle
var needle = 'le'
var re = new RegExp(needle,'gi');
var haystack = 'I learned to play the Ukulele';

var results = new Array();//this is the results you want
while (re.exec(haystack)){
  results.push(re.lastIndex);
}

Edit: learn to spell RegExp

Also, I realized this isn't exactly what you want, as lastIndex tells us the end of the needle not the beginning, but it's close - you could push re.lastIndex-needle.length into the results array...

Edit: adding link

@Tim Down's answer uses the results object from RegExp.exec(), and all my Javascript resources gloss over its use (apart from giving you the matched string). So when he uses result.index, that's some sort of unnamed Match Object. In the MDC description of exec, they actually describe this object in decent detail.

In case you need to access a specific set of remote services you could use an intermediate reverse-proxy, to perform tls1.2 for you. This would save you from trying to patch or upgrade java1.6.

e.g. app -> proxy:http(5500)[tls-1.2] -> remote:https(443)

Configuration in its simplest form (one port per service) for apache httpd is:

Listen 127.0.0.1:5000
<VirtualHost *:5500>
    SSLProxyEngine On
    ProxyPass / https://remote-domain/
    ProxyPassReverse / https://remote-domain/
</VirtualHost>

Then instead of accessing https://remote-domain/ you access http://localhost:5500/

Also if you need to DoubleClick and make your Form bigger/smaller , you can use the First answer, create a global int variable, add 1 every time user clicks on the component you use for dragging. If variable == 2 then make your form bigger/smaller. Also use a timer for every half a sec or a second to make your variable = 0;

As of EF 5.0, you need to include the System.ComponentModel.DataAnnotations.Schema namespace.

I put this function in a util file in one of the apps in my project:

import logging
import re

from django.db import connection

logger = logging.getLogger(__name__)

def sql_logger():
    logger.debug('TOTAL QUERIES: ' + str(len(connection.queries)))
    logger.debug('TOTAL TIME: ' + str(sum([float(q['time']) for q in connection.queries])))

    logger.debug('INDIVIDUAL QUERIES:')
    for i, query in enumerate(connection.queries):
        sql = re.split(r'(SELECT|FROM|WHERE|GROUP BY|ORDER BY|INNER JOIN|LIMIT)', query['sql'])
        if not sql[0]: sql = sql[1:]
        sql = [(' ' if i % 2 else '') + x for i, x in enumerate(sql)]
        logger.debug('\n### {} ({} seconds)\n\n{};\n'.format(i, query['time'], '\n'.join(sql)))

Then, when needed, I just import it and call it from whatever context (usually a view) is necessary, e.g.:

# ... other imports
from .utils import sql_logger

class IngredientListApiView(generics.ListAPIView):
    # ... class variables and such

    # Main function that gets called when view is accessed
    def list(self, request, *args, **kwargs):
        response = super(IngredientListApiView, self).list(request, *args, **kwargs)

        # Call our function
        sql_logger()

        return response

It's nice to do this outside the template because then if you have API views (usually Django Rest Framework), it's applicable there too.

The only thing I found that worked was a post here: https://stackoverflow.com/a/44548729/9488229

I improved it, and now it provides all these features:

• Disable the button after click
• Show an animated loading icon using native bootstrap
• Re-enable the button after the page is done loading
• Text goes back to original when page loading is done

Javascript:

$(document).ready(function () {
    $('.btn').on('click', function() {
        var e=this;
        setTimeout(function() {
            e.innerHTML='<span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span> Searching...';
            e.disabled=true;
        },0);
        return true;
    });
});

Cool.

I also found the documentation regarding the E:

http://www.postgresql.org/docs/8.3/interactive/sql-syntax-lexical.html#SQL-SYNTAX-STRINGS

PostgreSQL also accepts "escape" string constants, which are an extension to the SQL standard. An escape string constant is specified by writing the letter E (upper or lower case) just before the opening single quote, e.g. E'foo'. (When continuing an escape string constant across lines, write E only before the first opening quote.) Within an escape string, a backslash character (\) begins a C-like backslash escape sequence, in which the combination of backslash and following character(s) represents a special byte value. \b is a backspace, \f is a form feed, \n is a newline, \r is a carriage return, \t is a tab. Also supported are \digits, where digits represents an octal byte value, and \xhexdigits, where hexdigits represents a hexadecimal byte value. (It is your responsibility that the byte sequences you create are valid characters in the server character set encoding.) Any other character following a backslash is taken literally. Thus, to include a backslash character, write two backslashes (\\). Also, a single quote can be included in an escape string by writing \', in addition to the normal way of ''.

Easy Way To Delete Item From state array in react:

when any data delete from database and update list without API calling that time you pass deleted id to this function and this function remove deleted recored from list

export default class PostList extends Component {_x000D_
  this.state = {_x000D_
      postList: [_x000D_
        {_x000D_
          id: 1,_x000D_

        }, {_x000D_
          id: 2,_x000D_
          name: 'In Stock Items',_x000D_

This is really strange... Once set, the default Charset is cached and it isn't changed while the class is in memory. Setting the "file.encoding" property with System.setProperty("file.encoding", "Latin-1"); does nothing. Every time Charset.defaultCharset() is called it returns the cached charset.

Here are my results:

Default Charset=ISO-8859-1
file.encoding=Latin-1
Default Charset=ISO-8859-1
Default Charset in Use=ISO8859_1

I'm using JVM 1.6 though.

(update)

Ok. I did reproduce your bug with JVM 1.5.

Looking at the source code of 1.5, the cached default charset isn't being set. I don't know if this is a bug or not but 1.6 changes this implementation and uses the cached charset:

JVM 1.5:

public static Charset defaultCharset() {
    synchronized (Charset.class) {
        if (defaultCharset == null) {
            java.security.PrivilegedAction pa =
                    new GetPropertyAction("file.encoding");
            String csn = (String) AccessController.doPrivileged(pa);
            Charset cs = lookup(csn);
            if (cs != null)
                return cs;
            return forName("UTF-8");
        }
        return defaultCharset;
    }
}

JVM 1.6:

public static Charset defaultCharset() {
    if (defaultCharset == null) {
        synchronized (Charset.class) {
            java.security.PrivilegedAction pa =
                    new GetPropertyAction("file.encoding");
            String csn = (String) AccessController.doPrivileged(pa);
            Charset cs = lookup(csn);
            if (cs != null)
                defaultCharset = cs;
            else
                defaultCharset = forName("UTF-8");
        }
    }
    return defaultCharset;
}

When you set the file encoding to file.encoding=Latin-1 the next time you call Charset.defaultCharset(), what happens is, because the cached default charset isn't set, it will try to find the appropriate charset for the name Latin-1. This name isn't found, because it's incorrect, and returns the default UTF-8.

As for why the IO classes such as OutputStreamWriter return an unexpected result,
the implementation of sun.nio.cs.StreamEncoder (witch is used by these IO classes) is different as well for JVM 1.5 and JVM 1.6. The JVM 1.6 implementation is based in the Charset.defaultCharset() method to get the default encoding, if one is not provided to IO classes. The JVM 1.5 implementation uses a different method Converters.getDefaultEncodingName(); to get the default charset. This method uses its own cache of the default charset that is set upon JVM initialization:

JVM 1.6:

public static StreamEncoder forOutputStreamWriter(OutputStream out,
        Object lock,
        String charsetName)
        throws UnsupportedEncodingException
{
    String csn = charsetName;
    if (csn == null)
        csn = Charset.defaultCharset().name();
    try {
        if (Charset.isSupported(csn))
            return new StreamEncoder(out, lock, Charset.forName(csn));
    } catch (IllegalCharsetNameException x) { }
    throw new UnsupportedEncodingException (csn);
}

JVM 1.5:

public static StreamEncoder forOutputStreamWriter(OutputStream out,
        Object lock,
        String charsetName)
        throws UnsupportedEncodingException
{
    String csn = charsetName;
    if (csn == null)
        csn = Converters.getDefaultEncodingName();
    if (!Converters.isCached(Converters.CHAR_TO_BYTE, csn)) {
        try {
            if (Charset.isSupported(csn))
                return new CharsetSE(out, lock, Charset.forName(csn));
        } catch (IllegalCharsetNameException x) { }
    }
    return new ConverterSE(out, lock, csn);
}

But I agree with the comments. You shouldn't rely on this property. It's an implementation detail.

No, you can't.

But as a solid workaround, I would suggest to classify that first div as position:relative and use div::before to create an underlying element containing your image. Classified as position:absolute you can move it anywhere relative to your initial div.

Don't forget to add content to that new element. Here's some example:

div {
  position: relative;
}    

div::before {
  content: ""; /* empty but necessary */
  position: absolute;
  background: ...
}

Note: if you want it to be 'on top' of the parent div, use div::after instead.

There is no "quick-and-dirty" way of doing this. I usually do:

mystring= string.Concat(mystring.Take(mystring.Length-1));

Update: Nowadays I would use JSON.

I also prefer to go with serialization to file. XML files fits mostly all requirements. You can use the ApplicationSettings build in but those have some restrictions and a defined but (for me) very strange behavior where they stored. I used them a lot and they work. But if you want to have full control how and where they stored I use another approach.

1. Make a class Somewhere with all your settings. I named it MySettings
2. Implement Save and Read for persistence
3. Use them in you application-code

Advantages:

• Very Simple approach.
• One Class for Settings. Load. Save.
• All your Settings are type safe.
• You can simplify or extend the logic to your needs (Versioning, many Profiles per User, etc.)
• It works very well in any case (Database, WinForms, WPF, Service, etc...)
• You can define where to store the XML files.
• You can find them and manipulate them either by code or manual
• It works for any deployment method I can imagine.

Disadvantages: - You have to think about where to store your settings files. (But you can just use your installation folder)

Here is a simple example (not tested)-

public class MySettings
{
    public string Setting1 { get; set; }
    public List<string> Setting2 { get; set; }

    public void Save(string filename)
    {
        using (StreamWriter sw = new StreamWriter(filename))
        {
            XmlSerializer xmls = new XmlSerializer(typeof(MySettings));
            xmls.Serialize(sw, this);
        }
    }
    public MySettings Read(string filename)
    {
        using (StreamReader sw = new StreamReader(filename))
        {
            XmlSerializer xmls = new XmlSerializer(typeof(MySettings));
            return xmls.Deserialize(sw) as MySettings;
        }
    }
}

And here is how to use it. It's possible to load default values or override them with the user's settings by just checking if user settings exist:

public class MyApplicationLogic
{
    public const string UserSettingsFilename = "settings.xml";
    public string _DefaultSettingspath = 
        Assembly.GetEntryAssembly().Location + 
        "\\Settings\\" + UserSettingsFilename;

    public string _UserSettingsPath = 
        Assembly.GetEntryAssembly().Location + 
        "\\Settings\\UserSettings\\" + 
        UserSettingsFilename;

    public MyApplicationLogic()
    {
        // if default settings exist
        if (File.Exists(_UserSettingsPath))
            this.Settings = Settings.Read(_UserSettingsPath);
        else
            this.Settings = Settings.Read(_DefaultSettingspath);
    }
    public MySettings Settings { get; private set; }

    public void SaveUserSettings()
    {
        Settings.Save(_UserSettingsPath);
    }
}

maybe someone get's inspired by this approach. This is how I do it now for many years and I'm quite happy with that.
