Maybe this is useful to anyone in the future, I have implemented a custom Authorize Attribute like this:

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

    public ClaimAuthorizeAttribute(string Claim)
    {
        _claim = Claim;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;
        if(user.Identity.IsAuthenticated && user.HasClaim(ClaimTypes.Name, _claim))
        {
            return;
        }

        context.Result = new ForbidResult();
    }
}

Apache Subversion supports path-based authorization that helps you configure granular permissions for user and group accounts on paths in your repositories (files or directories). Path-based authorization supports three access levels - No Access, Read Only and Read / Write.

Path-based authorization permissions are stored in per-repository or per-server authorization files with a special syntax. Here is an example from SVNBook:

[calc:/branches/calc/bug-142]
harry = rw
sally = r

When you require a complex permission structure with many paths and accounts you can benefit from a GUI-based permission management tools provided by VisualSVN Server:

• Server administrators can manage user and group permissions via the VisualSVN Server Manager console or PowerShell,
• Non-admin users can manage permissions via RepoCfg.

Non-admin users can manage permissions via the RepoCfg tool

curl -u username:password http://
curl -u username http://

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

http://curl.haxx.se/docs/manpage.html#-u

Note that you do not need --basic flag as it is the default.

Stop with whatever you were doing ! :)

Implement the RESTful client as a SERVICE and delegate the intensive network stuff to activity independent component: a SERVICE.

Watch this insightful video http://www.youtube.com/watch?v=xHXn3Kg2IQE where Virgil Dobjanschi is explaining his approach(es) to this challenge...

To send a POST request call:

        connection.setDoOutput(true); // Triggers POST.

If you want to sent text in the request use:

        java.io.OutputStreamWriter wr = new java.io.OutputStreamWriter(connection.getOutputStream());
        wr.write(textToSend);
        wr.flush();

$headers = array(
    'Authorization: Basic '. base64_encode($username.':'.$password),
);
...
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

No, that is not a valid production according to the "credentials" definition in RFC 2617. You give a valid auth-scheme, but auth-param values must be of the form token "=" ( token | quoted-string ) (see section 1.2), and your example doesn't use "=" that way.

All you need to do is a post request like below :-

POST https://www.googleapis.com/oauth2/v4/token
Content-Type: application/json

{
  "client_id": <client_id>,
  "client_secret": <client_secret>,
  "refresh_token": <refresh_token>,
  "grant_type": "refresh_token"
}

There is a Superuser Roles: root, which is a Built-In Roles, may meet your need.

You can work with the overridable HandleUnauthorizedRequest inside your custom AuthorizeAttribute

Like this:

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
    // Returns HTTP 401 by default - see HttpUnauthorizedResult.cs.
    filterContext.Result = new RedirectToRouteResult(
    new RouteValueDictionary 
    {
        { "action", "YourActionName" },
        { "controller", "YourControllerName" },
        { "parameterName", "YourParameterValue" }
    });
}

You can also do something like this:

private class RedirectController : Controller
{
    public ActionResult RedirectToSomewhere()
    {
        return RedirectToAction("Action", "Controller");
    }
}

Now you can use it in your HandleUnauthorizedRequest method this way:

filterContext.Result = (new RedirectController()).RedirectToSomewhere();

You can read the Name from WindowsIdentity:

var user = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
return Ok(user);

How do I set up the basic authorization?

All you need to do is use -u, --user USER[:PASSWORD]. Behind the scenes curl builds the Authorization header with base64 encoded credentials for you.

Example:

curl -u username:password -i -H 'Accept:application/json' http://example.com

One of the best posts I've ever come across regarding Security as it relates to REST is over at 1 RainDrop. The MySpace API's use OAuth also for security and you have full access to their custom channels in the RestChess code, which I did a lot of exploration with. This was demo'd at Mix and you can find the posting here.

In .Net Core You can use

return new ForbidResult();

instead of

return Unauthorized();

which has the advantage to redirecting to the default unauthorized page (Account/AccessDenied) rather than giving a straight 401

to change the default location modify your startup.cs

services.AddAuthentication(options =>...)
            .AddOpenIdConnect(options =>...)
            .AddCookie(options =>
            {
                options.AccessDeniedPath = "/path/unauthorized";

            })

just note, The different between the methods are, if the header is not exist

request.headers.get('your-header-name')

will return None or no exception, so you can use it like

if request.headers.get('your-header-name'):
    ....

but the following will throw an error

if request.headers['your-header-name'] # KeyError: 'your-header-name'
    ....

You can handle it by

if 'your-header-name' in request.headers:
   customHeader = request.headers['your-header-name']
   ....

Note there are serious security arguments against using Oauth 2:

one bleak article

and a more technical one

Note these are coming from Oauth 2's lead author.

Key points:

• Oauth 2 offers no security on top of SSL while Oauth 1 is transport-independent.

• in a sense SSL isn't secure in that the server does not verify the connection and the common client libraries make it easy to ignore failures.

  The problem with SSL/TLS, is that when you fail to verify the certificate on the client side, the connection still works. Any time ignoring an error leads to success, developers are going to do just that. The server has no way of enforcing certificate verification, and even if it could, an attacker will surely not.

• you can fat-finger away all of your security, which is much harder to do in OAuth 1.0:

  The second common potential problem are typos. Would you consider it a proper design when omitting one character (the ‘s’ in ‘https’) voids the entire security of the token? Or perhaps sending the request (over a valid and verified SSL/TLS connection) to the wrong destination (say ‘http://gacebook.com’?). Remember, being able to use OAuth bearer tokens from the command line was clearly a use case bearer tokens advocates promoted.

If anyone just wants to validate a bearer token in the authorize phase using the current security practices you can,

add this to your Startup/ConfigureServices

    services.AddSingleton<IAuthorizationHandler, BearerAuthorizationHandler>();
    services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer();

    services.AddAuthorization(options => options.AddPolicy("Bearer",
        policy => policy.AddRequirements(new BearerRequirement())
        )
    );

and this in your codebase,

public class BearerRequirement : IAuthorizationRequirement
{
    public async Task<bool> IsTokenValid(SomeValidationContext context, string token)
    {
        // here you can check if the token received is valid 
        return true;
    }
}

public class BearerAuthorizationHandler : AuthorizationHandler<BearerRequirement> 
{

    public BearerAuthorizationHandler(SomeValidationContext thatYouCanInject)
    {
       ...
    }

    protected override async Task HandleRequirementAsync(AuthorizationHandlerContext context, BearerRequirement requirement)
    {
        var authFilterCtx = (Microsoft.AspNetCore.Mvc.Filters.AuthorizationFilterContext)context.Resource;
        string authHeader = authFilterCtx.HttpContext.Request.Headers["Authorization"];
        if (authHeader != null && authHeader.Contains("Bearer"))
        {
            var token = authHeader.Replace("Bearer ", string.Empty);
            if (await requirement.IsTokenValid(thatYouCanInject, token))
            {
                context.Succeed(requirement);
            }
        }
    }
}

If the code doesn't reach context.Succeed(...) it will Fail anyway (401).

And then in your controllers you can use

 [Authorize(Policy = "Bearer", AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]

For those who use NSwag and need a custom header:

app.UseSwaggerUi3(typeof(Startup).GetTypeInfo().Assembly, settings =>
      {
          settings.GeneratorSettings.IsAspNetCore = true;
          settings.GeneratorSettings.OperationProcessors.Add(new OperationSecurityScopeProcessor("custom-auth"));

          settings.GeneratorSettings.DocumentProcessors.Add(
              new SecurityDefinitionAppender("custom-auth", new SwaggerSecurityScheme
                {
                    Type = SwaggerSecuritySchemeType.ApiKey,
                    Name = "header-name",
                    Description = "header description",
                    In = SwaggerSecurityApiKeyLocation.Header
                }));
        });            
    }

Swagger UI will then include an Authorize button.

Authentication is a process of verification:

• user identity in a system(username, login, phone number, email...) by providing a proof (secret key, biometrics, sms...). Multi-factor authentication as an extension.
• email checking using digital signature^[About]
• checksum

Authorization is the next step after Authentication. It is about permissions/roles/privileges to resources. OAuth (Open Authorization) is an example of Authorization

Kindly try below on postman :-

Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.

Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

When I turn off my Comodo Antivirus everything goes back normal. All other solutions suggested here went in vain. Somehow I figured out one solution.

If you are using Comodo Antivirus (Version 6.3/ For other versions search for similar options) the following solution would help you.

Open Comodo > Tasks > Advanced Tasks > Open Advanced Settings > Security Settings > Firewall > Firewall Settings > Advanced : Filter loopback traffic (e.g. 127.x.x.x, ::1)

Uncheck this "Filter loopback traffic" option, which prevents adb from normal working.

You can try something like this

r = requests.get(ENDPOINT, params=params, headers={'Authorization': 'Basic %s' %  API_KEY})

▲ is the Unicode black up-pointing triangle (?) while ▼ is the black down-pointing triangle (?).

You can just plug the characters (copied from the web) into this site for a lookup.

ok i had the same problem and i fix it like this by removing [] from [{"key":"value"}]:

1. in your php file make shure that you print like this

echo json_encode(array_shift($your_variable));

2. in your success function do this

 success: function (data) {
    var result = $.parseJSON(data);
      ('.yourclass').append(result['your_key1']);
      ('.yourclass').append(result['your_key2']);
       ..
    }

and also you can loop it if you want

I use the blow function in my GeneralUtils class, check it may be useful

    public String getFieldType(Object o) {
    if (o == null) {
        return "Unable to identify the class name";
    }
    return o.getClass().getName();
}

Using HttpClient 3.x, you need to do this:

Protocol easyHttps = new Protocol("https", new EasySSLProtocolSocketFactory(), 443);
Protocol.registerProtocol("https", easyHttps);

An implementation of EasySSLProtocolSocketFactory can be found here.

You can always do something like this:

update  mytable t
set     SomeColumn = c.ComputedValue
from    (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id 

You can now also use with statement inside update

update  mytable t
set     SomeColumn = c.ComputedValue
from    (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
         select *, 42 as ComputedValue, abc.ComputedValue_new  from mytable n1
           inner join abc on n1.id=abc.id) c
where t.id = c.id 

I assume your game has a main loop, and all your sprites are in a list called sprites.

In your main loop, get all events, and check for the MOUSEBUTTONDOWN or MOUSEBUTTONUP event.

while ... # your main loop
  # get all events
  ev = pygame.event.get()

  # proceed events
  for event in ev:

    # handle MOUSEBUTTONUP
    if event.type == pygame.MOUSEBUTTONUP:
      pos = pygame.mouse.get_pos()

      # get a list of all sprites that are under the mouse cursor
      clicked_sprites = [s for s in sprites if s.rect.collidepoint(pos)]
      # do something with the clicked sprites...

So basically you have to check for a click on a sprite yourself every iteration of the mainloop. You'll want to use mouse.get_pos() and rect.collidepoint().

Pygame does not offer event driven programming, as e.g. cocos2d does.

Another way would be to check the position of the mouse cursor and the state of the pressed buttons, but this approach has some issues.

if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()):
  print ("You have opened a chest!")

You'll have to introduce some kind of flag if you handled this case, since otherwise this code will print "You have opened a chest!" every iteration of the main loop.

handled = False

while ... // your loop

  if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()) and not handled:
    print ("You have opened a chest!")
    handled = pygame.mouse.get_pressed()[0]

Of course you can subclass Sprite and add a method called is_clicked like this:

class MySprite(Sprite):
  ...

  def is_clicked(self):
    return pygame.mouse.get_pressed()[0] and self.rect.collidepoint(pygame.mouse.get_pos())

So, it's better to use the first approach IMHO.

This post might be old but i am just posting it incase it helps some other person, I would not advise to Create a .htaccess file in your web root and change the index. I feel it is better to follow the steps

1. Go to the conf folder of your apache folder mine is

   C:\Apache24\conf

2. Open the file named

   httpd.conf

3. Go to the section

   <IfModule dir_module>
      DirectoryIndex index.html 
   
    </IfModule>
   

4. Add index.php to it as shown below

    <IfModule dir_module>
     DirectoryIndex index.html index.php
   
   </IfModule>
   

This way, it still picks index.html and index.php as the default index but giving priority to index.html because index.html came before *index.php. By this I mean in you have both index.html and index.php in the same directory, the index.html will be used as the default index except you write **index.php* before index.hml

I hope it helps someone... Happy Coding

There seems to be a few details left out of your explanation, but I will do my best...

If these are NUL-terminated strings or the memory is pre-zeroed, you can just iterate down the length of the memory segment until you hit a NUL (0) character or the maximum length (whichever comes first). Use the string constructor, passing the buffer and the size determined in the previous step.

string retrieveString( char* buf, int max ) {

    size_t len = 0;
    while( (len < max) && (buf[ len ] != '\0') ) {
        len++;
    }

    return string( buf, len );

}

If the above is not the case, I'm not sure how you determine where a string ends.

Here is a trick though. You can map the Ctrl+Z keys. This can be achieved by editing the .vimrc file. Add the following lines in the '.vimrc` file.

nnoremap <c-z> :u<CR>      " Avoid using this**
inoremap <c-z> <c-o>:u<CR>

This may not the a preferred way, but can be used.

** Ctrl+Z is used in Linux to suspend the ongoing program/process.

The two answers are good. And I also suggest you a similar method:

<% @images.each.with_index do |page, index| %>
<% end %>

You might not see the difference between this and the accepted answer. Let me direct your eyes to these method calls: .each.with_index see how it's .each and then .with_index.

You cannot do this in C#. What you can do is have a out parameter or return your own class (or struct if you want it to be immutable).

public int GetDay(DateTime date, out string name)
{
  // ...
}

public DayOfWeek GetDay(DateTime date)
{
  // ...
}

public class DayOfWeek
{
  public int Day { get; set; }
  public string Name { get; set; }
}

Go a simple way to do this :-

Created one class to hold following information

• Level (number)
• Url (Url of the site)

Go the list of sites stored on a ArrayList object. And executed following query to sort it in descending order by Level.

var query = from MyClass object in objCollection 
    orderby object.Level descending 
    select object

Once I got the collection sorted in descending order, I wrote following code to get the Object that comes as top row

MyClass topObject = query.FirstRow<MyClass>()

This worked like charm.

I wanted to do the same, and I had first problems with the split function, then problems with installing pandas 0.15.2, so I went back to my old version, and wrote a little function that works very well. I hope this can help!

# input - df: a Dataframe, chunkSize: the chunk size
# output - a list of DataFrame
# purpose - splits the DataFrame into smaller chunks
def split_dataframe(df, chunk_size = 10000): 
    chunks = list()
    num_chunks = len(df) // chunk_size + 1
    for i in range(num_chunks):
        chunks.append(df[i*chunk_size:(i+1)*chunk_size])
    return chunks

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!

you can either use shuffle or sample . both of which come from random module.

import random
def shuffle(arr1):
    n=len(arr1)
    b=random.sample(arr1,n)
    return b

OR

import random
def shuffle(arr1):
    random.shuffle(arr1)
    return arr1

use grep -n -i null myfile.txt to output the line number in front of each match.

I dont think grep has a switch to print the count of total lines matched, but you can just pipe grep's output into wc to accomplish that:

grep -n -i null myfile.txt | wc -l

Graphically, the cron syntax for Quarz is (source):

+-------------------- second (0 - 59)
|  +----------------- minute (0 - 59)
|  |  +-------------- hour (0 - 23)
|  |  |  +----------- day of month (1 - 31)
|  |  |  |  +-------- month (1 - 12)
|  |  |  |  |  +----- day of week (0 - 6) (Sunday=0 or 7)
|  |  |  |  |  |  +-- year [optional]
|  |  |  |  |  |  |
*  *  *  *  *  *  * command to be executed 

So if you want to run a command every 30 minutes you can say either of these:

0 0/30 * * * * ?
0 0,30 * * * * ?

You can check crontab expressions using either of these:

• crontab.guru — (disclaimer: I am not related to that page at all, only that I find it very useful). This page uses UNIX style of cron that does not have seconds in it, while Spring does as the first field.
• Cron Expression Generator & Explainer - Quartz — cron formatter, allowing seconds also.

I just spent sometime debugging the same issue. Note, that issue might not be between different projects, but actually between several references in one project that depend on different versions of the same dll/assembly. In my case, issue was reference FastMember.dll versions mismatch that comes from two different NuGet packages in a single project. When I was given a project, it would not compile because NuGet packages were missing and VS refused to restore missing packages. Through the NuGet menu, I manually update all the NuGets to the latest version, that is when the warning appeared.

Notice, that Project file item includes which caused reference "C:\Users\ksd3jvp\Source\Temp\AITool\Misra\AMSAITool\packages\ClosedXML.0.94.2\lib\net46\ClosedXML.dll"

ClosedXML.dll comes from ClosedXML NuGet and it depends on FastMember.dll 1.3.0.0. On top of it, there is also FastMember Nuget in the project, and it has FastMember.dll 1.5.0.0. Mismatch !

I have uninstalled ClosedXML & FastMember NuGets, because I had binding redirect and installed just latest version of ClosedXML That fixed the issue !

From the standard

7.5.2 Element identifiers: the id and class attributes

Attribute definitions

id = name [CS]
This attribute assigns a name to an element. This name must be unique in a document.

class = cdata-list [CS]
This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

Yes, just put a space between them.

As a good example may be worth it to navigate to this project and see how to handle exiting processes grammatically or in this snippet from VM found in here

In angular 1.3, I think, they added a new function - $scope.$applyAsync(). This function calls apply later on - they say about 10 ms later at least. It is not perfect, but it does at least eliminate the annoying error.

On Charles' comment problem: to make things worse, let

Inner Join all_tab_comments C on T.owner = C.owner and T.table_name = C.table_name

ORA-01008: not all variables bound

Both statements execute fine in SQL Developer. The shortened code:

            Using con = New OracleConnection(cs)
                con.Open()
                Using cmd = con.CreateCommand()
                    cmd.CommandText = cmdText
                    cmd.Parameters.Add(pn, OracleDbType.NVarchar2, 250).Value = p
                    Dim tbl = New DataTable
                    Dim da = New OracleDataAdapter(cmd)
                    da.Fill(tbl)
                    Return tbl
                End Using
            End Using

using Oracle.ManagedDataAccess.dll Version 4.121.2.0 with the default settings in VS2015 on the .Net 4.61 platform.

So somewhere in the call chain, there might be a parser that is a bit too aggressively looking for one-line-comments started by -- in the commandText. But even if this would be true, the error message "not all variables bound" is at least misleading.

Settings > Language & input > Current keyboard > Hardware Switch ON.
It allows you to use your physical keyboard for input while at the same time showing the soft keyboard. I just tested it on Android Lollipop and it works.

You can't do it directly, you should provide your own way to check this. Eg.

class MyClass {
  Object attr1, attr2, attr3;

  public boolean isValid() {
    return attr1 != null && attr2 != null && attr3 != null;
  }
}

Or make all fields final and initialize them in constructors so that you can be sure that everything is initialized.

If you use Tomcat, add '-Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true' in VM properties.

I've had great success with TopShelf.

TopShelf is a Nuget package designed to make it easy to create .NET Windows apps that can run as console apps or as Windows Services. You can quickly hook up events such as your service Start and Stop events, configure using code e.g. to set the account it runs as, configure dependencies on other services, and configure how it recovers from errors.

From the Package Manager Console (Nuget):

Install-Package Topshelf

Refer to the code samples to get started.

Example:

HostFactory.Run(x =>                                 
{
    x.Service<TownCrier>(s =>                        
    {
       s.ConstructUsing(name=> new TownCrier());     
       s.WhenStarted(tc => tc.Start());              
       s.WhenStopped(tc => tc.Stop());               
    });
    x.RunAsLocalSystem();                            

    x.SetDescription("Sample Topshelf Host");        
    x.SetDisplayName("Stuff");                       
    x.SetServiceName("stuff");                       
}); 

TopShelf also takes care of service installation, which can save a lot of time and removes boilerplate code from your solution. To install your .exe as a service you just execute the following from the command prompt:

myservice.exe install -servicename "MyService" -displayname "My Service" -description "This is my service."

You don't need to hook up a ServiceInstaller and all that - TopShelf does it all for you.

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

To highlight a few points:

The docs recommend using an install environment: https://conda.io/docs/user-guide/install/download.html#choosing-a-version-of-anaconda-or-miniconda

The version archive is here: https://repo.continuum.io/archive/

The version history is here: https://docs.anaconda.com/anaconda/release-notes

"Anaconda3 then its python 3.x and if it is Anaconda2 then its 2.x" - +1 papbiceps

The version archive is sorted newest at the top, but Anaconda2 ABOVE Anaconda3.

The maven plugin and embedded Tomcat are usable work-arounds (I like second better because you can debug) but actual web server integration is a feature only available in intelij paid editions.

How to create CascadeClassifier :

1. Open this link : https://github.com/opencv/opencv/tree/master/data/haarcascades
2. Right click on where you find "haarcascade_frontalface_default.xml"
3. Click on "Save link as"
4. Save it into the same folder in which your file is.
5. Include this line in your file face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_frontalface_default.xml")

I wrote a VBA file to add a tool cleaning these abnormally biggest file. This script clear all columns and rows after the last cells realy used to reset the last cells ( [Ctrl]+[End] ), and it also provides enable images compression.

I dev an AddIns with auto install (just run it with macro enabled) to include in context menu many new buttons:

1. Optimize
2. Optimize and Save
3. Disable Optimizer

This is based on KB of Microsoft office 2003 and answer of PP. with personals improvement :

1. add compression of images
2. fix bug for Columns
3. feat compatibility with excel 2007 - 2010 - ... (more than 255 columns)

I had this problem and then found these pages: Here you can see that apache library is deprecated, but it's not removed, so it should work. It doesn't.

See.

And here you can see how to include apache library to your project

See.

I resolved problem by adding following to my build.gradle file as recommended in second link.

android {
    useLibrary 'org.apache.http.legacy'
}

However this only works if you are using gradle 1.3.0-beta2 or greater, so you will have to add this to buildscript dependencies if you are on a lower version:

classpath 'com.android.tools.build:gradle:1.3.0-beta2'

Hope this helps.

So I used the overflowing jquery library: https://github.com/kevinmarx/overflowing

After installing the library, if you want to assign the class overflowing to all overflowing elements, you simply run:

$('.targetElement').overflowing('.parentElement')

This will then give the class overflowing, as in <div class="targetElement overflowing"> to all elements that are overflowing. You could then add this to some event handler(click, mouseover) or other function that will run the above code so that it updates dynamically.

condition ? truth : false;

If the condition is true then evaluate the first expression. If the condition is false, evaluate the second expression.

It is called the Conditional Operator and it is a type of Ternary Operation.

To ignore an entire directory in Git, the easiest way is to include a .gitignore file within the target directory which simply contains "*".

An illustrative example,

Example System

/root/
    .gitignore
    /dirA/
        someFile1.txt
        someFile2.txt
    /dirB/
        .gitignore
        someFile3.txt
        someFile4.txt

Goal

• ignore the contents of /dirB/

Top Level (/root/.gitignore)

• This is where your standard gitignore info goes (e.g. a “~Untitled.docx”, some private dirs, etc.). “dirB/“ can certainly be placed here, if needed

Ignored Directory (/root/dirB/.gitignore)

• Git watches for gitignore at every step of the file system so anytime you have ignore specifications to apply then toss it in, generating a new gitignore for that dir

• dirB/.gitignore then just reads as “*” and all contents are ignored completely, itself and all files!

And it's that simple :)

for (Integer i : l)
{
    if (i.intValue() == 5){
            itemsToRemove.add(i);
            break;
    }
}

The catch is the after removing the element from the list if you skip the internal iterator.next() call. it still works! Though I dont propose to write code like this it helps to understand the concept behind it :-)

Cheers!

You should use ExecuteScalar() (which returns the first row first column) instead of ExecuteNonQuery() (which returns the no. of rows affected).

You should refer differences between executescalar and executenonquery for more details.

Hope it helps!

You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.

In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.

select
    p.product_id,
    p.type_id,
    p.product_name,
    p.type,
    case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
    Product p

    inner join Product_Type pt on
        pt.type_id = p.type_id

    left join Product_ArtistAuthor paa on
        paa.artist_id = p.artist_id
where
    p.product_id = $pid

I used a left join since I don't know the business logic.

f1 = open("input1.txt", "r")
print(f1.readline())

const is similar to static we can access both varables with class name but diff is static variables can be modified and const can not.

Following Class does the trick:

org.apache.lucene.analysis.miscellaneous.ASCIIFoldingFilter

As I observed in my code. If once the value is fetched of body from Response, its become blank.

String str = response.body().string();  // {response:[]}

String str1  = response.body().string();  // BLANK

So I believe after fetching once the value from body, it become empty.

Suggestion : Store it in String, that can be used many time.

When you make a POST HttpWebRequest, you must specify the length of the data you are sending, something like:

string data = "something you need to send"
byte[] postBytes = Encoding.ASCII.GetBytes(data);
request.ContentLength = postBytes.Length;

if you are not sending any data, just set it to 0, that means you just have to add to your code this line:

request.ContentLength = 0;

Usually, if you are not sending any data, chosing the GET method instead is wiser, as you can see in the HTTP RFC

Another non-bash 4 way.

#!/bin/bash

# A pretend Python dictionary with bash 3 
ARRAY=( "cow:moo"
        "dinosaur:roar"
        "bird:chirp"
        "bash:rock" )

for animal in "${ARRAY[@]}" ; do
    KEY=${animal%%:*}
    VALUE=${animal#*:}
    printf "%s likes to %s.\n" "$KEY" "$VALUE"
done

echo -e "${ARRAY[1]%%:*} is an extinct animal which likes to ${ARRAY[1]#*:}\n"

You could throw an if statement for searching in there as well. if [[ $var =~ /blah/ ]]. or whatever.

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

     foreach (DataRow row in DataRow row in GridView1.Rows)
        {
            foreach (DataColumn c in GridView1.Columns)

               bool ckbVal = (bool)(row[c.ColumnName]);

        }

protected void finalize() throws Throwable {}

• every class inherits the finalize() method from java.lang.Object
• the method is called by the garbage collector when it determines no more references to the object exist
• the Object finalize method performs no actions but it may be overridden by any class
• normally it should be overridden to clean-up non-Java resources ie closing a file

• if overridding finalize() it is good programming practice to use a try-catch-finally statement and to always call super.finalize(). This is a safety measure to ensure you do not inadvertently miss closing a resource used by the objects calling class

  protected void finalize() throws Throwable {
       try {
           close();        // close open files
       } finally {
           super.finalize();
       }
   }
  

• any exception thrown by finalize() during garbage collection halts the finalization but is otherwise ignored

• finalize() is never run more than once on any object

quoted from: http://www.janeg.ca/scjp/gc/finalize.html

You could also check this article:

• Object finalization and cleanup

If you have a list of lists, you only needed to use ...

import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.

Suppose you want to write that in the same file, you can do as follows:

Set-Content -Path "C:\temp\Newtext.txt" -Value (get-content -Path "c:\Temp\Newtext.txt" | Select-String -Pattern 'H\|159' -NotMatch)

Use sed, but let the shell do the math, with the goal being to use the d command by giving a range (to remove the last 23 lines):

sed -i "$(($(wc -l < file)-22)),\$d" file

To remove the last 3 lines, from inside out:

$(wc -l < file)

Gives the number of lines of the file: say 2196

We want to remove the last 23 lines, so for left side or range:

$((2196-22))

Gives: 2174 Thus the original sed after shell interpretation is:

sed -i '2174,$d' file

With -i doing inplace edit, file is now 2173 lines!

If you want to save it into a new file, the code is:

sed -i '2174,$d' file > outputfile

One Liner:

modalPresentationStyle is required to be set on the navigationController which is being presented.

iOS 13 and below iOS version fullScreen with overCurrentContext and navigationController

Tested Code

let controller = UIViewController()
let navigationController = UINavigationController(rootViewController: controller)
navigationController.modalPresentationStyle = .overCurrentContext
self.navigationController?.present(navigationController, animated: true, completion: nil)

modalPresentationStyle require to set at navigationController.

You can also use

$('#myModal').hasClass('show');

BufferedReader br;
FileInputStream fin;
try {
    fin = new FileInputStream(fileName);
    br = new BufferedReader(new InputStreamReader(fin));

    /*Path pathToFile = Paths.get(fileName);
    br = Files.newBufferedReader(pathToFile,StandardCharsets.US_ASCII);*/

    String line = br.readLine();
    while (line != null) {
        String[] attributes = line.split(",");
        Movie movie = createMovie(attributes);
        movies.add(movie);
        line = br.readLine();
    }
    fin.close();
    br.close();
} catch (FileNotFoundException e) {
    System.out.println("Your Message");
} catch (IOException e) {
    System.out.println("Your Message");

It works for me. Hope It will help you too.

I was experiencing this segmentation fault after upgrading dlib on RPI. I tracebacked the stack as suggested by Shiplu Mokaddim above and it settled on an OpenBLAS library.

Since OpenBLAS is also multi-threaded, using it in a muilt-threaded application will exponentially multiply threads until segmentation fault. For multi-threaded applications, set OpenBlas to single thread mode.

In python virtual environment, tell OpenBLAS to only use a single thread by editing:

    $ workon <myenv>
    $ nano .virtualenv/<myenv>/bin/postactivate

and add:

    export OPENBLAS_NUM_THREADS=1 
    export OPENBLAS_MAIN_FREE=1

After reboot I was able to run all my image recognition apps on rpi3b which were previously crashing it.

I ran into this when checking on a null or empty string

if (x == NULL || x == '') {

changed it to

if (is.null(x) || x == '') {

I found these instructions on a blog post that indicated this step, which worked for me (Windows 8, 64-bit):

Make sure that in windows features, you have both WCF options under .Net framework are ticked. So go to Control Panel –> Programs and Features –> Turn Windows Features ON/Off –> Features –> Add Features –> .NET Framework X.X Features. Make sure that .Net framework says it is installed, and make sure that the WCF Activation node underneath it is selected (checkbox ticked) and both options under WCF Activation are also checked.

These are:
* HTTP Activation
* Non-HTTP Activation
Both options need to be selected (checked box ticked).

It appears that your HTML syntax is incorrect for the table cell. Before you try the other idea below, confirm if this works or not... You can also try adding this to your table itself: table-layout:fixed.. .

<td style="overflow: hidden; width: 280px; text-align: left; valign: top; whitespace: nowrap;">
   [content]
</td>

New HTML

<td>
   <div class="MyClass"">
       [content]
   </div>
</td>

CSS Class:

.MyClass{
   height: 280px; 
   width: 456px; 
   overflow: hidden;
   white-space: nowrap;
}

This is a rehash of the previous answer but it's more likely to work on different mongodb versions.

I recommend use boolean;. You have to install the boolean module from cpan though.

I put commit .gitignore, which is a courtesy to other who may build my project that the following files are derived and should be ignored.

I usually do a hybrid. I like to make makefile generate the .gitignore file since the makefile will know all the files associated with the project -derived or otherwise. Then have a top level project .gitignore that you check in, which would ignore the generated .gitignore files created by the makefile for the various sub directories.

So in my project, I might have a bin sub directory with all the built executables. Then, I'll have my makefile generate a .gitignore for that bin directory. And in the top directory .gitignore that lists bin/.gitignore. The top one is the one I check in.

If you got a lot configurations the output might be pretty lengthy. To just show dependencies for the runtime configuration, run

It's a table-valued function, but you're using it as a scalar function.

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

But... also consider changing your function into an inline TVF, as it'll perform better.

In the official getting started example (https://docs.docker.com/compose/gettingstarted/) with the following docker-compose.yml:

version: '3'
services:
  web:
    build: .
    ports:
     - "5000:5000"
  redis:
    image: "redis:alpine"

After you start this with docker-compose up, you can easily shell into either your redis container or your web container with:

docker-compose exec redis sh
docker-compose exec web sh 

I used Storm + SQLite for a small project, and was pretty happy with it until I added multiprocessing. Trying to use the database from multiple processes resulted in a "Database is locked" exception. I switched to SQLAlchemy, and the same code worked with no problems.

The third parameter of String.prototype.replace() function was never defined as a standard, so most browsers simply do not implement it.

The best way is to use regular expression with g (global) flag.

var myStr = 'this,is,a,test';_x000D_
var newStr = myStr.replace(/,/g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

Still have issues?

It is important to note, that regular expressions use special characters that need to be escaped. As an example, if you need to escape a dot (.) character, you should use /\./ literal, as in the regex syntax a dot matches any single character (except line terminators).

var myStr = 'this.is.a.test';_x000D_
var newStr = myStr.replace(/\./g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

If you need to pass a variable as a replacement string, instead of using regex literal you may create RegExp object and pass a string as the first argument of the constructor. The normal string escape rules (preceding special characters with \ when included in a string) will be necessary.

var myStr = 'this.is.a.test';_x000D_
var reStr = '\\.';_x000D_
var newStr = myStr.replace(new RegExp(reStr, 'g'), '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.

My original question for this was how to both have an element of a fixed aspect, but to fit that within a specified container exactly, which makes it a little fiddly. If you simply want an individual element to maintain its aspect ratio it is a lot easier.

The best method I've come across is by giving an element zero height and then using percentage padding-bottom to give it height. Percentage padding is always proportional to the width of an element, and not its height, even if its top or bottom padding.

W3C Padding Properties

So utilising that you can give an element a percentage width to sit within a container, and then padding to specify the aspect ratio, or in other terms, the relationship between its width and height.

.object {
    width: 80%; /* whatever width here, can be fixed no of pixels etc. */
    height: 0px;
    padding-bottom: 56.25%;
}
.object .content {
    position: absolute;
    top: 0px;
    left: 0px;
    height: 100%;
    width: 100%;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    padding: 40px;
}

So in the above example the object takes 80% of the container width, and then its height is 56.25% of that value. If it's width was 160px then the bottom padding, and thus the height would be 90px - a 16:9 aspect.

The slight problem here, which may not be an issue for you, is that there is no natural space inside your new object. If you need to put some text in for example and that text needs to take it's own padding values you need to add a container inside and specify the properties in there.

Also vw and vh units aren't supported on some older browsers, so the accepted answer to my question might not be possible for you and you might have to use something more lo-fi.

Yes, the order of elements in JSON arrays is preserved. From RFC 7159 -The JavaScript Object Notation (JSON) Data Interchange Format (emphasis mine):

An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.

An array is an ordered sequence of zero or more values.

The terms "object" and "array" come from the conventions of JavaScript.

Some implementations do also preserve the order of JSON objects as well, but this is not guaranteed.

To differentiate between scroll up/down in jQuery, you could use:

var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$('#yourDiv').bind(mousewheelevt, function(e){

    var evt = window.event || e //equalize event object     
    evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible               
    var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF

    if(delta > 0) {
        //scroll up
    }
    else{
        //scroll down
    }   
});

This method also works in divs that have overflow:hidden.

I successfully tested it in FireFox, IE and Chrome.

Found the code that I referred to in my comment above. To test it, do this:

1. In Sheet1 change the cell height and width of say A1 as shown in the snapshot below.
2. Format the cell by right clicking on it to show time format
3. Add two buttons (form controls) on the worksheet and name them as shown in the snapshot
4. Paste this code in a module
5. Right click on the Start Timer button on the sheet and click on Assign Macros. Select StartTimer macro.
6. Right click on the End Timer button on the sheet and click on Assign Macros. Select EndTimer macro.

Now click on Start Timer button and you will see the time getting updated in cell A1. To stop time updates, Click on End Timer button.

Code (TRIED AND TESTED)

Public Declare Function SetTimer Lib "user32" ( _
ByVal HWnd As Long, ByVal nIDEvent As Long, _
ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long

Public Declare Function KillTimer Lib "user32" ( _
ByVal HWnd As Long, ByVal nIDEvent As Long) As Long

Public TimerID As Long, TimerSeconds As Single, tim As Boolean
Dim Counter As Long

'~~> Start Timer
Sub StartTimer()
    '~~ Set the timer for 1 second
    TimerSeconds = 1
    TimerID = SetTimer(0&, 0&, TimerSeconds * 1000&, AddressOf TimerProc)
End Sub

'~~> End Timer
Sub EndTimer()
    On Error Resume Next
    KillTimer 0&, TimerID
End Sub

Sub TimerProc(ByVal HWnd As Long, ByVal uMsg As Long, _
ByVal nIDEvent As Long, ByVal dwTimer As Long)
    '~~> Update value in Sheet 1
    Sheet1.Range("A1").Value = Time
End Sub

SNAPSHOT

You can't break from a Groovy each loop, but you can break from a java "enhanced" for loop.

def a = [1, 2, 3, 4, 5, 6, 7]

for (def i : a) {
    if (i < 2)
        continue
    if (i > 5)
        break
    println i
}

Output:

2
3
4
5

This might not fit for absolutely every situation but it's helped for me :)

    from  wp_postmeta m 
    inner join wp_postmeta n
      on m.post_id  = n.post_id
    inner join wp_posts p
      ON m.post_id=p.id 
    and m.meta_key = '_sale_price'
    and  n.meta_key = '_regular_price'
     AND p.post_type = 'product';



 update  wp_postmeta m

 set m.meta_value = n.meta_value;

I encountered the same problem, but I check find that I hadn't the parent table. So I just edit the parent migration in front of the child migration. Just do it.

even i came across the same situation and one of my mentor put this idea across to myself.

step:1 when clicked on the button on which we should show the drop down menu. then add the below class name "more_wrap_background" to the current active page like shown below

$('.ui-page-active').append("<div class='more_wrap_background' id='more-wrap-bg'> </div>");

step-2 then add a clicks for the div tag like

$(document).on('click', '#more-wrap-bg', hideDropDown);

where hideDropDown is the function to be called to hide drop down menu

Step-3 and important step while hiding the drop down menu is that remove that class you that added earlier like

$('#more-wrap-bg').remove();

I am removing by using its id in the above code

.more_wrap_background {
  top: 0;
  padding: 0;
  margin: 0;
  background: rgba(0, 0, 0, 0.1);
  position: fixed;
  display: block;
  width: 100% !important;
  z-index: 999;//should be one less than the drop down menu's z-index
  height: 100% !important;
}

I think a much easier way is to use ASIHTTPRequest. Three lines of code can accomplish this:

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadDestinationPath:@"/path/to/my_file.txt"];
[request startSynchronous];

Link to Reference

UPDATE: I should mention that ASIHTTPRequest is no longer maintained. The author has specifically advised people to use other framework instead, like AFNetworking

I would like to run an automation test in different environments.
So I add this to command maven command:

spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=productionEnv1"

Short Answer

To copy myfile.txt to /foo/bar/myfile.txt, use:

mkdir -p /foo/bar && cp myfile.txt $_

How does this work?

There's a few components to this, so I'll cover all the syntax step by step.

The mkdir utility, as specified in the POSIX standard, makes directories. The -p argument, per the docs, will cause mkdir to

Create any missing intermediate pathname components

meaning that when calling mkdir -p /foo/bar, mkdir will create /foo and /foo/bar if /foo doesn't already exist. (Without -p, it will instead throw an error.

The && list operator, as documented in the POSIX standard (or the Bash manual if you prefer), has the effect that cp myfile.txt $_ only gets executed if mkdir -p /foo/bar executes successfully. This means the cp command won't try to execute if mkdir fails for one of the many reasons it might fail.

Finally, the $_ we pass as the second argument to cp is a "special parameter" which can be handy for avoiding repeating long arguments (like file paths) without having to store them in a variable. Per the Bash manual, it:

expands to the last argument to the previous command

In this case, that's the /foo/bar we passed to mkdir. So the cp command expands to cp myfile.txt /foo/bar, which copies myfile.txt into the newly created /foo/bar directory.

Note that $_ is not part of the POSIX standard, so theoretically a Unix variant might have a shell that doesn't support this construct. However, I don't know of any modern shells that don't support $_; certainly Bash, Dash, and zsh all do.

A final note: the command I've given at the start of this answer assumes that your directory names don't have spaces in. If you're dealing with names with spaces, you'll need to quote them so that the different words aren't treated as different arguments to mkdir or cp. So your command would actually look like:

mkdir -p "/my directory/name with/spaces" && cp "my filename with spaces.txt" "$_"

In WPF, you use a DispatcherTimer.

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

Depending on the file which will be put into filesystem, as long as that file is not a malware, then that would be safe.

But don't worry to write/read file(s) to File System directory, cause you can tighten that directory security (include it's inheritance) by give a proper access right and security restriction. eg: read/write/modify.

By default, File System, Local Storage, and Storage directory are located on "\Users[Current User]\AppData\Local\Google\Chrome\User Data\Default" directory.

However you can customize it by using "--user-data-dir" flag.

And this is a sample:

"C:\Program Files (x86)\Google\Application\chrome.exe" --user-data-dir="C:\Chrome_Data\OO7" --allow-file-access-from-files

Hope this helps anyone.

Because my keyboard has an O key.
It does not have a T or an O key.

I suspect most people are similarly lazy and use O when they mean T because it's easier to type.

Since this hasn't been closed yet, here are a few more options.

• Use Ctrl+x followed by Ctrl+e to open the current line in the editor specified by $FCEDIT or $EDITOR or emacs (tried in that order).
• If you ran the command earlier, hit Ctrl+r for a reverse history search and type option25 (in this case). The line will be displayed. Hit Tab to start editing at this point.
• Use history expansion with the s/// modifier. E.g. !-2:s/--option25/--newoption/ would rerun the second-to-last command, but replace option25. To modify the last ./cmd command, use the !string syntax: !./cmd:s/--option25/--newoption/
  Any delimiter may be used in place of / in the substitution.
• If editing the previous line, you can use quick substitution: ^--option25^--newoption
• Character search. This was mentioned by Pax, and can be done in regular emacs-mode with Ctrl+] for forward search, and Ctrl+Alt+] for backward search.

I recommend the second option. Ctrl+r is really handy and fast, no mucking about with editors, and you see the results before the command is run (unlike the history expansions).

I needed this functionality for multiple read more area's on one page implementing this into a Wordpress shortcode I ran into the same problem.

Design technically all of the read more span's on the page have a fixed height. And I wanted to be able to expand them separately to an auto height with a toggle. First click: 'expand to full height of text span', second click: 'collapse back to default height of 70px'

Html

 <span class="read-more" data-base="70" data-height="null">
     /* Lots of text determining the height of this span */
 </span>
 <button data-target='read-more'>Read more</button>

CSS

span.read-more {
    position:relative;
    display:block;
    overflow:hidden;
}

So above this looks very simple the data-base attribute I need to set the fixed height needed. The data-height attribute I used to store the actual (dynamic) height of the element.

The jQuery part

jQuery(document).ready(function($){

  $.fn.clickToggle = function(func1, func2) {
      var funcs = [func1, func2];
      this.data('toggleclicked', 0);
      this.click(function() {
          var data = $(this).data();
          var tc = data.toggleclicked;
          $.proxy(funcs[tc], this)();
          data.toggleclicked = (tc + 1) % 2;
      });
      return this;
  };

    function setAttr_height(key) {
        $(key).each(function(){
            var setNormalHeight = $(this).height();
            $(this).attr('data-height', setNormalHeight);
            $(this).css('height', $(this).attr('data-base') + 'px' );
        });
    }
    setAttr_height('.read-more');

    $('[data-target]').clickToggle(function(){
        $(this).prev().animate({height: $(this).prev().attr('data-height')}, 200);
    }, function(){
        $(this).prev().animate({height: $(this).prev().attr('data-base')}, 200);
    });

});

First I've used a clickToggle function for my first and second click. The second function is more important: setAttr_height() All of the .read-more elements have their actual heights set on page load in the base-height attribute. After that the base height is set through the jquery css function.

With both of our attributes set we now can toggle between them in a smooth way. Only chang the data-base to your desired (fixed)height and switch the .read-more class for your own ID

You can all see it working in a fiddle FIDDLE

If you want to replace those ugly ==> <== with something else

tail -n +1 *.txt | sed -e 's/==>/\n###/g' -e 's/<==/###/g' >> "files.txt"

explanation:

tail -n +1 *.txt - output all files in folder with header

sed -e 's/==>/\n###/g' -e 's/<==/###/g' - replace ==> with new line + ### and <== with just ###

>> "files.txt" - output all to a file

+ means a space only in application/x-www-form-urlencoded content, such as the query part of a URL:

http://www.example.com/path/foo+bar/path?query+name=query+value

In this URL, the parameter name is query name with a space and the value is query value with a space, but the folder name in the path is literally foo+bar, not foo bar.

%20 is a valid way to encode a space in either of these contexts. So if you need to URL-encode a string for inclusion in part of a URL, it is always safe to replace spaces with %20 and pluses with %2B. This is what eg. encodeURIComponent() does in JavaScript. Unfortunately it's not what urlencode does in PHP (rawurlencode is safer).

Oracle's free SQL Developer will do this:

http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html

You just find your table, right-click on it and choose Export Data->Insert

This will give you a file with your insert statements. You can also export the data in SQL Loader format as well.

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id is a newly generated ObjectId.

You can read more about the Types object at Mongoose#Types documentation.

You can run a single test class, but not a single method within a test class. You use the simple name of the class not the fully-qualified name of the class. So, if you have a test in "org.sonatype.test.MyTest" and that is the only test you want to run, your command line would look like this:

mvn test -Dtest=MyTest

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

You can use awk which is a utility/language designed for data extraction

e.g. for 1.2/3.4

>echo 1.2 3.4 | awk '{ print $2/$1 }'

If you can't edit the source of the class (why not?), then you need to iterate over the list and compare each item based on the four criteria mentioned ("title, author, url and description").

To do this in a performant way, I would create a new class, something like BlogKey which contains those four elements and which properly implements equals() and hashCode(). You can then iterate over the original list, constructing a BlogKey for each and adding to a HashMap:

Map<BlogKey, Blog> map = new HashMap<BlogKey, Blog>();
for (Blog blog : blogs) {
     BlogKey key = createKey(blog);
     if (!map.containsKey(key)) {
          map.put(key, blog);
     }
}
Collection<Blog> uniqueBlogs = map.values();

However the far simplest thing is to just edit the original source code of Blog so that it correctly implements equals() and hashCode().

This one can be useful as well:

if (Debugger.IsAttached)
{
...
}

The current C++ standard does not have hash maps, but the coming C++0x standard does, and these are already supported by g++ in the shape of "unordered maps":

#include <unordered_map>
#include <iostream>
#include <string>
using namespace std;

int main() {
    unordered_map <string, int> m;
    m["foo"] = 42;
    cout << m["foo"] << endl;
}

In order to get this compile, you need to tell g++ that you are using C++0x:

g++ -std=c++0x main.cpp

These maps work pretty much as std::map does, except that instead of providing a custom operator<() for your own types, you need to provide a custom hash function - suitable functions are provided for types like integers and strings.

If you want to replace several keys at once (preserving order):

/**
 * Rename keys of an array
 * @param array $array (asoc)
 * @param array $replacement_keys (indexed)
 * @return array
 */
function rename_keys($array, $replacement_keys)  {
      return array_combine($replacement_keys, array_values($array));
}

Usage:

$myarr = array("a" => 22, "b" => 144, "c" => 43);
$newkeys = array("x","y","z");
print_r(rename_keys($myarr, $newkeys));
//must return: array("x" => 22, "y" => 144, "z" => 43);

Set it with a px value. Changing the code like below should work

el.css('marginLeft', mrg + 'px');

One of the best source of information on this topic is Paul Irish's Bulletproof @font-face syntax article.

Read it and you will end with something like:

/* definition */
@font-face {
  font-family: EntezareZohoor2;
  src: url('fonts/EntezareZohoor2.eot');
  src: url('fonts/EntezareZohoor2.eot?') format('?'),
       url('fonts/EntezareZohoor2.woff') format('woff'),
       url('fonts/EntezareZohoor2.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

/* use */
body {
    font-family: EntezareZohoor2, Tahoma, serif;
}

You can add a sequence of numbers very easily with

data$ID <- seq.int(nrow(data))

If you are already using library(tidyverse), you can use

data <- tibble::rowid_to_column(data, "ID")

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:

function modify_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
        wp_enqueue_script('jquery');
    }
}
add_action('init', 'modify_jquery');

Code taken from here: http://www.wpbeginner.com/wp-themes/replace-default-wordpress-jquery-script-with-google-library/

You could try using df['column'].str. and then use any string function. Pandas documentation includes those like split

To update all possible packages I used conda update --update-all

It works!

RegisteredClientScriptBlock adds the script at the top of the page on the post-back with no assurance about the order, meaning that either the call is being injected after the function declaration (your js file with the function is inlined after your call) or when the script tries to execute the div is probably not there yet 'cause the page is still rendering. A good idea is probably to simulate the two scenarios I described above on firebug and see if you get similar errors.

My guess is this would work if you append the script at the bottom of the page with RegisterStartupScript - worth a shot at least.

Anyway, as an alternative solution if you add the runat="server" attribute to the div you will be able to access it by its id in the codebehind (without reverting to js - how cool that might be), and make it disappear like this:

data.visible = false

A connection string for SQL Server should look more like: "Server= localhost; Database= employeedetails; Integrated Security=True;"

If you have a named instance of SQL Server, you'll need to add that as well, e.g., "Server=localhost\sqlexpress"

Just in case this helps someone, I was getting this error because I completely missed the stated fact that the scope prefix must not be used when calling a local scope. So if you defined a local scope in your model like this:

public function scopeRecentFirst($query)
{
    return $query->orderBy('updated_at', 'desc');
}

You should call it like:

$CurrentUsers = \App\Models\Users::recentFirst()->get();

Note that the prefix scope is not present in the call.

using sklearn library preprocessing class

from sklearn.impute import SimpleImputer
missingvalues = SimpleImputer(missing_values = np.nan, strategy = 'mean', axis = 0)
missingvalues = missingvalues.fit(x[:,1:3])
x[:,1:3] = missingvalues.transform(x[:,1:3])

Note: In the recent version parameter missing_values value change to np.nan from NaN

Performance wise there is no difference. The only purpose of having const_iterator over iterator is to manage the accessesibility of the container on which the respective iterator runs. You can understand it more clearly with an example:

std::vector<int> integers{ 3, 4, 56, 6, 778 };

If we were to read & write the members of a container we will use iterator:

for( std::vector<int>::iterator it = integers.begin() ; it != integers.end() ; ++it )
       {*it = 4;  std::cout << *it << std::endl; }

If we were to only read the members of the container integers you might wanna use const_iterator which doesn't allow to write or modify members of container.

for( std::vector<int>::const_iterator it = integers.begin() ; it != integers.end() ; ++it )
       { cout << *it << endl; }

NOTE: if you try to modify the content using *it in second case you will get an error because its read-only.

If I'm not mislead, you just need to set your local branches to track their pairs in the origin server.

Using your command line, you can try

git checkout mybranch
git branch --set-upstream-to=origin/mybranch

That will configure something as an equivalent of your local branch in the server. I'll bet that Android Studio is complaining about the lack of that.

If someone knows how to do this using the GUI of that IDE, that would be interesting to read. :)

I've made the stupidest error. Passed app id into MobileAds.initialize from one app and used placement id in loadAd from another admob app.

Once I corrected placement id all come to work.

Center iframe

One solution is:

div {
  text-align:center;
  width:100%;
}
iframe{
  width: 200px;
}

<div>
  <iframe></iframe>
</div>

JSFiddle: https://jsfiddle.net/h9gTm/

edit: vertical align added

css:

div {
    text-align: center;
    width: 100%;
    vertical-align: middle;
    height: 100%;
    display: table-cell;
}
.iframe{
  width: 200px;
}
div,
body,
html {
    height: 100%;
    width: 100%;
}
body{
    display: table;
}

JSFiddle: https://jsfiddle.net/h9gTm/1/

Edit: FLEX solution

Using display: flex on the <div>

div {
    display: flex;
    align-items: center;
    justify-content: center;
}

Wikipedia has us covered:

In computer science, overhead is generally considered any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to attain a particular goal. It is a special case of engineering overhead.

I use expr. It returns a non-zero if you try to add a zero to a non-numeric value:

if expr -- "$number" + 0 > /dev/null 2>&1
then
    echo "$number is a number"
else
    echo "$number isn't a number"
fi

It might be possible to use bc if you need non-integers, but I don't believe bc has quite the same behavior. Adding zero to a non-number gets you zero and it returns a value of zero too. Maybe you can combine bc and expr. Use bc to add zero to $number. If the answer is 0, then try expr to verify that $number isn't zero.

$out.='<option value="'.$key.'">'.$value["name"];

me funciono con esta

"<a  href='javascript:void(0)' onclick='cargar_datos_cliente(\"$row->DSC_EST\")' class='button micro asignar margin-none'>Editar</a>";

Try like

HTML in PHP :

echo "<a href='".$link_address."'>Link</a>";

Or even you can try like

echo "<a href='$link_address'>Link</a>";

Or you can use PHP in HTML like

PHP in HTML :

<a href="<?php echo $link_address;?>"> Link </a>

If we use=> .equals method

if(obj.equals(null))  

// Which mean null.equals(null) when obj will be null.

When your obj will be null it will throw Null Point Exception.

so we should use ==

if(obj == null)

it will compare the references.

If you're changing the prototype of the built-in 'function' object it's possible you're running into a browser bug or race condition by modifying a fundamental built-in object.

Test it in multiple browsers to find out.

A facade should not be described as a class which contains a lot of other classes. It is in fact a interface to this classes and should make the usage of the classes easier otherwise the facade class is useless.

It's just a different syntax. Instead of

foreach ($a as $v) {
    # ...
}

You could write this:

foreach ($a as $v):
    # ...
endforeach;

They will function exactly the same; it's just a matter of style. (Personally I have never seen anyone use the second form.)

try : android:stateListAnimator="@null"

A simple way to do that in VBA is:

YourText = "c:\excel\text.txt"
xString = Mid(YourText, 2 + Len(YourText) - InStr(StrReverse(YourText), "\" ))

It should be like this

$(this).text($(this).text().replace('N/A, ', ''))

One another way is to use the same thing what firebase uses.

For example when user logs in, firebase stores below details in local storage. When user comes back to the page, firebase uses the same method to identify if user should be logged in automatically.

ATTN: As this is neither listed or recommended by firebase. You can call this method un-official way of doing this. Which means later if firebase changes their inner working, this method may not work. Or in short. Use at your own risk! :)

You should be able to set your credentials like this:

git remote set-url origin https://<USERNAME>:<PASSWORD>@bitbucket.org/path/to/repo.git

You can get the remote url like this:

git config --get remote.origin.url

Here is a way which allows to remove points after a certain number of points plotted:

import matplotlib.pyplot as plt
# generate axes object
ax = plt.axes()

# set limits
plt.xlim(0,10) 
plt.ylim(0,10)

for i in range(10):        
     # add something to axes    
     ax.scatter([i], [i]) 
     ax.plot([i], [i+1], 'rx')

     # draw the plot
     plt.draw() 
     plt.pause(0.01) #is necessary for the plot to update for some reason

     # start removing points if you don't want all shown
     if i>2:
         ax.lines[0].remove()
         ax.collections[0].remove()

Assuming the rectangle is represented by three points A,B,C, with AB and BC perpendicular, you only need to check the projections of the query point M on AB and BC:

0 <= dot(AB,AM) <= dot(AB,AB) &&
0 <= dot(BC,BM) <= dot(BC,BC)

AB is vector AB, with coordinates (Bx-Ax,By-Ay), and dot(U,V) is the dot product of vectors U and V: Ux*Vx+Uy*Vy.

Update. Let's take an example to illustrate this: A(5,0) B(0,2) C(1,5) and D(6,3). From the point coordinates, we get AB=(-5,2), BC=(1,3), dot(AB,AB)=29, dot(BC,BC)=10.

For query point M(4,2), we have AM=(-1,2), BM=(4,0), dot(AB,AM)=9, dot(BC,BM)=4. M is inside the rectangle.

For query point P(6,1), we have AP=(1,1), BP=(6,-1), dot(AB,AP)=-3, dot(BC,BP)=3. P is not inside the rectangle, because its projection on side AB is not inside segment AB.

The other answers were good but they involve javascript or they doesn't center the video horizontally AND vertically.

You can use this full CSS solution to have a video that simulate the background-size: cover property:

  video {
    position: fixed;           // Make it full screen (fixed)
    right: 0;
    bottom: 0;
    z-index: -1;               // Put on background

    min-width: 100%;           // Expand video
    min-height: 100%;
    width: auto;               // Keep aspect ratio
    height: auto;

    top: 50%;                  // Vertical center offset
    left: 50%;                 // Horizontal center offset

    -webkit-transform: translate(-50%,-50%);
    -moz-transform: translate(-50%,-50%);
    -ms-transform: translate(-50%,-50%);
    transform: translate(-50%,-50%);         // Cover effect: compensate the offset

    background: url(bkg.jpg) no-repeat;      // Background placeholder, not always needed
    background-size: cover;
  }

Just put your globals in the file you are importing.

Another example to output date and time using zero as a fill character on instances of single digit values: 2017-06-04 18:13:02

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

int main()
{
    time_t t = time(0);   // Get time now
    struct tm * now = localtime(&t);
    cout.fill('0');
    cout << (now->tm_year + 1900) << '-'
        << setw(2) << (now->tm_mon + 1) << '-'
        << setw(2) << now->tm_mday << ' '
        << setw(2) << now->tm_hour << ':'
        << setw(2) << now->tm_min << ':'
        << setw(2) << now->tm_sec
        << endl;
    return 0;
}

There's been a fair amount of recent research in considering how REST HTTP calls could replace the message queue concept.

If you introduce the concept of a process and a task as a resource, the need for middle messaging layer starts to evaporate.

Ex:

POST /task/name
    - Returns a 202 accepted status immediately
    - Returns a resource url for the created task: /task/name/X
    - Returns a resource url for the started process: /process/Y

GET /process/Y
    - Returns status of ongoing process

A task can have multiple steps for initialization, and a process can return status when polled or POST to a callback URL when complete.

This is dead simple, and becomes quite powerful when you realize that you can now subscribe to an rss/atom feed of all running processes and tasks without any middle layer. Any queuing system is going to require some sort of web front end anyway, and this concept has it built in without another layer of custom code.

Your resources exist until you delete them, which means you can view historical information long after the process and task complete.

You have built in service discovery, even for a task that has multiple steps, without any extra complicated protocols.

GET /task/name
    - returns form with required fields

POST (URL provided form's "action" attribute)

Your service discovery is an HTML form - a universal and human readable format.

The entire flow can be used programmatically or by a human, using universally accepted tools. It's a client driven, and therefore RESTful. Every tool created for the web can drive your business processes. You still have alternate message channels by POSTing asynchronously to a separate array of log servers.

After you consider it for a while, you sit back and start to realize that REST may just eliminate the need for a messaging queue and an ESB altogether.

numpy.random.rand(row, column) generates random numbers between 0 and 1, according to the specified (m,n) parameters given. So use it to create a (m,n) matrix and multiply the matrix for the range limit and sum it with the high limit.

Analyzing: If zero is generated just the low limit will be held, but if one is generated just the high limit will be held. In order words, generating the limits using rand numpy you can generate the extreme desired numbers.

import numpy as np

high = 10
low = 5
m,n = 2,2

a = (high - low)*np.random.rand(m,n) + low

Output:

a = array([[5.91580065, 8.1117106 ],
          [6.30986984, 5.720437  ]])

In .net VB - you could achieve control over columns and rows with the following in your razor file:

@Html.EditorFor(Function(model) model.generalNotes, New With {.htmlAttributes = New With {.class = "someClassIfYouWant", .rows = 5,.cols=6}})

In addition to adding these attributes to your Id column:

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public Guid Id { get; set; }

in your migration you should change your CreateTable to add the defaultValueSQL property to your column i.e.:

Id = c.Guid(nullable: false, identity: true, defaultValueSql: "newsequentialid()"),

This will prevent you from having to manually touch your database which, as you pointed out in the comments, is something you want to avoid with Code First.

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

Great answers, but just wanted to mention a gotcha that "pass" keyword will not work in the if/else part of the list-comprehension (as posted in the examples mentioned above).

#works
list1 = [10, 20, 30, 40, 50]
newlist2 = [x if x > 30 else x**2 for x in list1 ]
print(newlist2, type(newlist2))

#but this WONT work
list1 = [10, 20, 30, 40, 50]
newlist2 = [x if x > 30 else pass for x in list1 ]
print(newlist2, type(newlist2))

This is tried and tested on python 3.4. Error is as below:

newlist2 = [x if x > 30 else pass for x in list1 ]                                    
SyntaxError: invalid syntax

So, try to avoid pass-es in list comprehensions

if ($string =~ m/something/) {
   # Do work
}

Where something is a regular expression.

Use Token when...

Federation is desired. For example, you want to use one provider (Token Dispensor) as the token issuer, and then use your api server as the token validator. An app can authenticate to Token Dispensor, receive a token, and then present that token to your api server to be verified. (Same works with Google Sign-In. Or Paypal. Or Salesforce.com. etc)

Asynchrony is required. For example, you want the client to send in a request, and then store that request somewhere, to be acted on by a separate system "later". That separate system will not have a synchronous connection to the client, and it may not have a direct connection to a central token dispensary. a JWT can be read by the asynchronous processing system to determine whether the work item can and should be fulfilled at that later time. This is, in a way, related to the Federation idea above. Be careful here, though: JWT expire. If the queue holding the work item does not get processed within the lifetime of the JWT, then the claims should no longer be trusted.

Cient Signed request is required. Here, request is signed by client using his private key and server would validate using already registered public key of the client.

You can use JSON.parse() (which is a built in function that will probably force you to wrap it with try-catch statements).

Or use some JSON parsing npm library, something like json-parse-or

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

inside OnCreate method :-

{

    Button b = (Button)findViewById(R.id.button1);
    b.setOnClickListener((View.OnClickListener)this);

    b = (Button)findViewById(R.id.button2);
    b.setOnClickListener((View.OnClickListener)this);
} 

@Override
public void OnClick(View v){

    switch(v.getId()){
         case R.id.button1:
             //whatever
             break;

         case R.id.button2:
             //whatever
             break;
}

Try this:

par(adj = 0)
plot(1, 1, main = "Title")

or equivalent:

plot(1, 1, main = "Title", adj = 0)

adj = 0 produces left-justified text, 0.5 (the default) centered text and 1 right-justified text. Any value in [0, 1] is allowed.

However, the issue is that this will also change the position of the label of the x-axis and y-axis.

You have two options:

OPTION 1:

You can use removeProperty method. It will remove a style from an element.

el.style.removeProperty('zoom');

OPTION 2:

You can set it to the default value:

el.style.zoom = "";

The effective zoom will now be whatever follows from the definitions set in the stylesheets (through link and style tags). So this syntax will only modify the local style of this element.

Make sure the required dlls are exported (or copied manually) to the bin folder when building your application.

Yes. Although I use the following code.

.carousel.fade
{
    opacity: 1;

    .item
    {
        -moz-transition: opacity ease-in-out .7s;
        -o-transition: opacity ease-in-out .7s;
        -webkit-transition: opacity ease-in-out .7s;
        transition: opacity ease-in-out .7s;
        left: 0 !important;
        opacity: 0;
        top:0;
        position:absolute;
        width: 100%;
        display:block !important;
        z-index:1;
        &:first-child{
            top:auto;
            position:relative;
        }

        &.active
        {
            opacity: 1;
            -moz-transition: opacity ease-in-out .7s;
            -o-transition: opacity ease-in-out .7s;
            -webkit-transition: opacity ease-in-out .7s;
            transition: opacity ease-in-out .7s;
            z-index:2;
        }
    }
}

Then change the class on the carousel from "carousel slide" to "carousel fade". This works in safari, chrome, firefox, and IE 10. It will correctly downgrade in IE 9, however, the nice face effect doesn't happen.

Edit: Since this answer has gotten so popular I've added the following which rewritten as pure CSS instead of the above which was LESS:

.carousel.fade {
  opacity: 1;
}
.carousel.fade .item {
  -moz-transition: opacity ease-in-out .7s;
  -o-transition: opacity ease-in-out .7s;
  -webkit-transition: opacity ease-in-out .7s;
  transition: opacity ease-in-out .7s;
  left: 0 !important;
  opacity: 0;
  top:0;
  position:absolute;
  width: 100%;
  display:block !important;
  z-index:1;
}
.carousel.fade .item:first-child {
  top:auto;
  position:relative;
}
.carousel.fade .item.active {
  opacity: 1;
  -moz-transition: opacity ease-in-out .7s;
  -o-transition: opacity ease-in-out .7s;
  -webkit-transition: opacity ease-in-out .7s;
  transition: opacity ease-in-out .7s;
  z-index:2;
}

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

I had the same problem. This worked for me:

• In VB go to Tools » References
• Uncheck the library "Crystal Analysis Common Controls 1.0". Or any library.
• Just leave these 5 references:
  1. Visual Basic For Applications (This is the library that defines the VBA language.)
  2. Microsoft Excel Object Library (This defines all of the elements of Excel.)
  3. OLE Automation (This specifies the types for linking and embedding documents and for automation of other applications and the "plumbing" of the COM system that Excel uses to communicate with the outside world.)
  4. Microsoft Office (This defines things that are common to all Office programs such as Command Bars and Command Bar controls.)
  5. Microsoft Forms 2.0 This is required if you are using a User Form. This library defines things like the user form and the controls that you can place on a form.
• Then Save.

This answer mentions Json.NET but stops short of telling you how you can use Json.NET to serialize a dictionary:

return JsonConvert.SerializeObject( myDictionary );

As opposed to JavaScriptSerializer, myDictionary does not have to be a dictionary of type <string, string> for JsonConvert to work.

int64_t is guaranteed by the C99 standard to be exactly 64 bits wide on platforms that implement it, there's no such guarantee for a long which is at least 32 bits so it could be more.

§7.18.1.3 Exact-width integer types 1 The typedef name intN_t designates a signed integer type with width N , no padding bits, and a two’s complement representation. Thus, int8_t denotes a signed integer type with a width of exactly 8 bits.

I encountered this error when "" was added by mistake to my command line arguments when altering properties for "All Configurations". Removing them from RightClickProject->Properties->Configuration Properties->Debugging->Command Arguments allowed it to run in the debugger again.

@Stephen Bailey

To complete your answer, you can also delegate the user rights to the project manager, through a plain text file in your repository.

To do that, you set up your SVN database with a default authz file containing the following:

###########################################################################
# The content of this file always precedes the content of the
# $REPOS/admin/acl_descriptions.txt file.
# It describes the immutable permissions on main folders.
###########################################################################
[groups]
svnadmins = xxx,yyy,....

[/]
@svnadmins = rw
* = r
[/admin]
@svnadmins = rw
@projadmins = r
* =

[/admin/acl_descriptions.txt]
@projadmins = rw

This default authz file authorizes the SVN administrators to modify a visible plain text file within your SVN repository, called '/admin/acl_descriptions.txt', in which the SVN administrators or project managers will modify and register the users.

Then you set up a pre-commit hook which will detect if the revision is composed of that file (and only that file).

If it is, this hook's script will validate the content of your plain text file and check if each line is compliant with the SVN syntax.

Then a post-commit hook will update the \conf\authz file with the concatenation of:

• the TEMPLATE authz file presented above
• the plain text file /admin/acl_descriptions.txt

The first iteration is done by the SVN administrator, who adds:

[groups]
projadmins = zzzz

He commits his modification, and that updates the authz file.

Then the project manager 'zzzz' can add, remove or declare any group of users and any users he wants. He commits the file and the authz file is updated.

That way, the SVN administrator does not have to individually manage any and all users for all SVN repositories.

I would like to add to the answers of BalusC and Pascal Thivent another common use of insertable=false, updatable=false:

Consider a column that is not an id but some kind of sequence number. The responsibility for calculating the sequence number may not necessarily belong to the application.

For example, sequence number starts with 1000 and should increment by one for each new entity. This is easily done, and very appropriately so, in the database, and in such cases these configurations makes sense.

It's and old post, but it's new for me. So, it is straight forward! In this part of the code:

 public boolean onNavigationItemSelected(MenuItem item) {

} , I bound an ImageView to the LinearLayout, which contains the ImageView from the example, listed below. Mind: it's the same code you get when you start a new project, and choose the template "Navigation Drawer Activity":

<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="@dimen/nav_header_vertical_spacing"
android:src="@android:drawable/sym_def_app_icon" />

I gave the LinearLayout and ID, inside nav_header_main.xml (in my case I chose 'navigation_header_container' , so it went this way:

LinearLayout lV = (LinearLayout) findViewById(R.id.navigation_header_container);

    ivCloseDrawer = (ImageView) lV.findViewById(R.id.imageView);
    ivCloseDrawer.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            drawer.closeDrawer(GravityCompat.START);
        }
    });

Note: I have a private ImageView ivCloseDrawer declared at the top, before onCreate (MainActivity).

It worked fine! Hope it helps, Best Regards.

Yes, if you redirect the output, it won't appear on the console. Use tee.

ls 2>&1 | tee /tmp/ls.txt

l = [1,2,3,4,5]
sum = 0
for x in l:
    sum = sum + x

And you can change l for any list you want.

Another solution would be using [class.active].

Example :

<ol class="breadcrumb">
    <li [class.active]="step=='step1'" (click)="step='step1'">Step1</li>
</ol>

std::map<Key, Value> ? SortedDictionary<TKey, TValue>

std::unordered_map<Key, Value> ? Dictionary<TKey, TValue>

In C++, almost everything is possible! If you have no way to get private data, then you have to hack. Do it only for testing!

class A {
     int iData;
};

int main ()
{
    A a;
    struct ATwin { int pubData; }; // define a twin class with public members
    reinterpret_cast<ATwin*>( &a )->pubData = 42; // set or get value

    return 0;
}

Include both left and right version with pre-allocation. This is as fast as RegExp impl for small chunks but it goes faster as the chunk size grows. And it is memory efficent.

function chunkLeft (str, size = 3) {
  if (typeof str === 'string') {
    const length = str.length
    const chunks = Array(Math.ceil(length / size))
    for (let i = 0, index = 0; index < length; i++) {
      chunks[i] = str.slice(index, index += size)
    }
    return chunks
  }
}

function chunkRight (str, size = 3) {
  if (typeof str === 'string') {
    const length = str.length
    const chunks = Array(Math.ceil(length / size))
    if (length) {
      chunks[0] = str.slice(0, length % size || size)
      for (let i = 1, index = chunks[0].length; index < length; i++) {
        chunks[i] = str.slice(index, index += size)
      }
    }
    return chunks
  }
}

console.log(chunkRight())  // undefined
console.log(chunkRight(''))  // []
console.log(chunkRight('1'))  // ["1"]
console.log(chunkRight('123'))  // ["123"]
console.log(chunkRight('1234'))  // ["1", "234"]
console.log(chunkRight('12345'))  // ["12", "345"]
console.log(chunkRight('123456'))  // ["123", "456"]
console.log(chunkRight('1234567'))  // ["1", "234", "567"]

This one took me about half a day to figure out but this is what worked for me. Inside the rootViewController that initializes the navigationController, I put this code inside my viewDidAppear method:

//set bar color
[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:85.0/255.0 green:143.0/255.0 blue:220.0/255.0 alpha:1.0]];
//optional, i don't want my bar to be translucent
[self.navigationController.navigationBar setTranslucent:NO];
//set title and title color
[self.navigationItem setTitle:@"Title"];
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];
//set back button color
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor,nil] forState:UIControlStateNormal];
//set back button arrow color
[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

You can do it using the "collapse" directive: http://jsfiddle.net/iscrow/Es4L3/ (check the two "Note" in the HTML).

              <ul class="nav">

That is, you need to store the collapsed state in a variable, and changing the collapsed also by (simply) changing the value of that variable.

Release 0.14 added a uib- prefix to components:

https://github.com/angular-ui/bootstrap/wiki/Migration-guide-for-prefixes

Change: collapse to uib-collapse.

you would need a parking lot, that holds a multi-dimensional array (specified in the constructor) of a type "space". The parking lot can keep track of how many spaces are taken via calls to functions that fill and empty spaces.Space can hold an enumerated type that tells what kind of space it is. Space also has a method taken(). for the valet parking, just find the first space thats open and put the car there. You will also need a Car object to put in the space, that holds whether it is a handicapped, compact, or regular vehicle.

class ParkingLot
{
    Space[][] spaces;

    ParkingLot(wide, long); // constructor

    FindOpenSpace(TypeOfCar); // find first open space where type matches
}

enum TypeOfSpace = {compact, handicapped, regular };
enum TypeOfCar = {compact, handicapped, regular };

class Space
{
    TypeOfSpace type;
    bool empty;
    // gets and sets here
    // make sure car type
}

class car
{
    TypeOfCar type;
}

JSON Schema is not intended to be feature equivalent with XML Schema. There are features in one but not in the other.

In general you can create a mapping from XML to JSON and back again, but that is not the case for XML schema and JSON schema.

That said, if you have mapped a XML file to JSON, it is quite possible to craft an JSON Schema that validates that JSON in nearly the same way that the XSD validates the XML. But it isn't a direct mapping. And it is not possible to guarantee that it will validate the JSON exactly the same as the XSD validates the XML.

For this reason, and unless the two specs are made to be 100% feature compatible, migrating a validation system from XML/XSD to JSON/JSON Schema will require human intervention.

You are really mixing together two different things.

Use dir(), vars() or the inspect module to get what you are interested in (I use __builtins__ as an example; you can use any object instead).

>>> l = dir(__builtins__)
>>> d = __builtins__.__dict__

Print that dictionary however fancy you like:

>>> print l
['ArithmeticError', 'AssertionError', 'AttributeError',...

or

>>> from pprint import pprint
>>> pprint(l)
['ArithmeticError',
 'AssertionError',
 'AttributeError',
 'BaseException',
 'DeprecationWarning',
...

>>> pprint(d, indent=2)
{ 'ArithmeticError': <type 'exceptions.ArithmeticError'>,
  'AssertionError': <type 'exceptions.AssertionError'>,
  'AttributeError': <type 'exceptions.AttributeError'>,
...
  '_': [ 'ArithmeticError',
         'AssertionError',
         'AttributeError',
         'BaseException',
         'DeprecationWarning',
...

Pretty printing is also available in the interactive debugger as a command:

(Pdb) pp vars()
{'__builtins__': {'ArithmeticError': <type 'exceptions.ArithmeticError'>,
                  'AssertionError': <type 'exceptions.AssertionError'>,
                  'AttributeError': <type 'exceptions.AttributeError'>,
                  'BaseException': <type 'exceptions.BaseException'>,
                  'BufferError': <type 'exceptions.BufferError'>,
                  ...
                  'zip': <built-in function zip>},
 '__file__': 'pass.py',
 '__name__': '__main__'}

Setting the CurrentCell and then calling BeginEdit(true) works well for me.

The following code shows an eventHandler for the KeyDown event that sets a cell to be editable.

My example only implements one of the required key press overrides but in theory the others should work the same. (and I'm always setting the [0][0] cell to be editable but any other cell should work)

    private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Tab && dataGridView1.CurrentCell.ColumnIndex == 1)
        {
            e.Handled = true;
            DataGridViewCell cell = dataGridView1.Rows[0].Cells[0];
            dataGridView1.CurrentCell = cell;
            dataGridView1.BeginEdit(true);               
        }
    }

If you haven't found it previously, the DataGridView FAQ is a great resource, written by the program manager for the DataGridView control, which covers most of what you could want to do with the control.

Beware of triggers. Maybe the issue is with some operation in the trigger for inserted rows.

To complete the answer, it could work something like this...

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
switch (types) {
   case UIRemoteNotificationTypeAlert:
   case UIRemoteNotificationTypeBadge:
       // For enabled code
       break;
   case UIRemoteNotificationTypeSound:
   case UIRemoteNotificationTypeNone:
   default:
       // For disabled code
       break;
}

edit: This is not right. since these are bit-wise stuff, it wont work with a switch, so I ended using this:

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
UIRemoteNotificationType typesset = (UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
if((types & typesset) == typesset)
{
    CeldaSwitch.chkSwitch.on = true;
}
else
{
    CeldaSwitch.chkSwitch.on = false;
}

Your data types are mismatched when you are retrieving the field values.

Also check how you store your enums, default is ORDINAL (numeric value stored in database), but STRING (name of enum stored in database) is also an option. Make sure the Entity in your code and the Model in your database are exactly the same.

I had an enum mismatch. It was set to default (ORDINAL) but the database model was expecting a string VARCHAR2(100char). Solution: @Enumerated(EnumType.STRING)

This code works for me:

public void Run()
{
    Dog myDog = new Dog();
    myDog.Name= "Foo";
    myDog.Color = DogColor.Brown;

    System.Console.WriteLine("{0}", myDog.ToString());

    MemoryStream stream = SerializeToStream(myDog);

    Dog newDog = (Dog)DeserializeFromStream(stream);

    System.Console.WriteLine("{0}", newDog.ToString());
}

Where the types are like this:

[Serializable]
public enum DogColor
{
    Brown,
    Black,
    Mottled
}

[Serializable]
public class Dog
{
    public String Name
    {
        get; set;
    }

    public DogColor Color
    {
        get;set;
    }

    public override String ToString()
    {
        return String.Format("Dog: {0}/{1}", Name, Color);
    }
}

and the utility methods are:

public static MemoryStream SerializeToStream(object o)
{
    MemoryStream stream = new MemoryStream();
    IFormatter formatter = new BinaryFormatter();
    formatter.Serialize(stream, o);
    return stream;
}

public static object DeserializeFromStream(MemoryStream stream)
{
    IFormatter formatter = new BinaryFormatter();
    stream.Seek(0, SeekOrigin.Begin);
    object o = formatter.Deserialize(stream);
    return o;
}

This is the only "simple" way to do this in SQL Server without some giant convoluted created function or executed sql string call, both of which are terrible solutions:

1. create a temp table
2. openrowset your stored procedure data into it

EXAMPLE:

INSERT INTO #YOUR_TEMP_TABLE
SELECT * FROM OPENROWSET ('SQLOLEDB','Server=(local);TRUSTED_CONNECTION=YES;','set fmtonly off EXEC [ServerName].dbo.[StoredProcedureName] 1,2,3')

Note: You MUST use 'set fmtonly off', AND you CANNOT add dynamic sql to this either inside the openrowset call, either for the string containing your stored procedure parameters or for the table name. Thats why you have to use a temp table rather than table variables, which would have been better, as it out performs temp table in most cases.

I was dealing with this running Artifactory version 5.8.4. The "Set Me Up" function would generate settings.xml as follows:

<servers>
    <server>
      <username>${security.getCurrentUsername()}</username>
      <password>${security.getEscapedEncryptedPassword()!"AP56eMPz8L12T5u4J6rWdqWqyhQ"}</password>
      <id>central</id>
    </server>
    <server>
      <username>${security.getCurrentUsername()}</username>
      <password>${security.getEscapedEncryptedPassword()!"AP56eMPz8L12T5u4J6rWdqWqyhQ"}</password>
      <id>snapshots</id>
    </server>
</servers>

After using the mvn deploy -e -X switch, I noticed the credentials were not accurate. I removed the ${security.getCurrentUsername()} and replaced it with my username and removed ${security.getEscapedEncryptedPassword()!""} and just put my encrypted password which worked for me:

<servers>
    <server>
      <username>username</username>
      <password>AP56eMPz8L12T5u4J6rWdqWqyhQ</password>
      <id>central</id>
    </server>
    <server>
      <username>username</username>
      <password>AP56eMPz8L12T5u4J6rWdqWqyhQ</password>
      <id>snapshots</id>
    </server>
</servers>

Hope this helps!

I know this isn't a direct answer to your question but it does offer one solution to your problem. Python 2.7.9 includes PIP and SetupTools, if you update to this version you will have one solution to your problem.

In my case 'await' never finished because of exception while executing the request, e.g. server not responding, etc. Surround it with try..catch to identify what happened, it'll also complete your 'await' gracefully.

public async Task<Stuff> GetStuff(string id)
{
    string path = $"/api/v2/stuff/{id}";
    try
    {
        HttpResponseMessage response = await client.GetAsync(path);
        if (response.StatusCode == HttpStatusCode.OK)
        {
            string json = await response.Content.ReadAsStringAsync();
            return JsonUtility.FromJson<Stuff>(json);
        }
        else
        {
            Debug.LogError($"Could not retrieve stuff {id}");
        }
    }
    catch (Exception exception)
    {
        Debug.LogError($"Exception when retrieving stuff {exception}");
    }
    return null;
}

I'd like to clarify one small gotcha here. You must use CustomVideoMode1 before CustomVideoMode2, etc. VirtualBox recognizes these modes in order starting from 1 and if you skip a number, it will not recognize anything at or beyond the number you skipped. This caught me by surprise.

Don't use the classes in thejava.io package, instead use the java.nio package . The latter has a FileLock class. You can apply a lock to a FileChannel.

 try {
        // Get a file channel for the file
        File file = new File("filename");
        FileChannel channel = new RandomAccessFile(file, "rw").getChannel();

        // Use the file channel to create a lock on the file.
        // This method blocks until it can retrieve the lock.
        FileLock lock = channel.lock();

        /*
           use channel.lock OR channel.tryLock();
        */

        // Try acquiring the lock without blocking. This method returns
        // null or throws an exception if the file is already locked.
        try {
            lock = channel.tryLock();
        } catch (OverlappingFileLockException e) {
            // File is already locked in this thread or virtual machine
        }

        // Release the lock - if it is not null!
        if( lock != null ) {
            lock.release();
        }

        // Close the file
        channel.close();
    } catch (Exception e) {
    }

-(void)saveToUserDefaults:(NSString*)string_to_store keys:(NSString *)key_for_the_String
{
    NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];

    if (standardUserDefaults) {
        [standardUserDefaults setObject:string_to_store forKey:key_for_the_String];
        [standardUserDefaults synchronize];
    }
}

And call it by:

[self saveToUserDefaults:@"string_to_store" : @"key_for_the_string"];

Retrieve the string by using:

NSString * stored_string = [[NSUserDefaults standardUserDefaults] stringforkey:key_for_the_String]

if (string.IsNullOrEmpty(myString)) {
   //
}

To access helpers from your own controllers, just use:

OrdersController.helpers.order_number(@order)

The problem might be in the rest of the html, the part that you didn't post.

With this example (I just closed the open tags):

<a class="item" ng-href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026" href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026">
<div class="col-lg-2 col-sm-3 col-xs-4 item-list-image">
<img ng-src="csa/images/library/Service_Design.png" src="csa/images/library/Service_Design.png">
</div>
<div class="col-lg-8 col-sm-9 col-xs-8">
<div class="col-xs-12">
    <p>
    <strong class="ng-binding">Smoke Sequential</strong>
    </p>
    </div>
</div>
</a>

I was able to find the element without trouble with:

driver.findElement(By.linkText("Smoke Sequential")).click();

If there is more text inside the element, you could try a find by partial link text:

driver.findElement(By.partialLinkText("Sequential")).click();

Typically you want to cancel the previous ajax request and ignore it's coming response, only when a new ajax request of that instance is started, for this purpose, do the following:

Example: getting some comments from API:

// declare an ajax request's cancelToken (globally)
let ajaxRequest = null; 

function getComments() {

    // cancel  previous ajax if exists
    if (ajaxRequest ) {
        ajaxRequest.cancel(); 
    }

    // creates a new token for upcomming ajax (overwrite the previous one)
    ajaxRequest = axios.CancelToken.source();  

    return axios.get('/api/get-comments', { cancelToken: ajaxRequest.token }).then((response) => {
        console.log(response.data)
    }).catch(function(err) {
        if (axios.isCancel(err)) {
           console.log('Previous request canceled, new request is send', err.message);
        } else {
               // handle error
        }
    });
}

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

To detect both positive and negative peaks, PeakDetect is helpful.

from peakdetect import peakdetect

peaks = peakdetect(data, lookahead=20) 
# Lookahead is the distance to look ahead from a peak to determine if it is the actual peak. 
# Change lookahead as necessary 
higherPeaks = np.array(peaks[0])
lowerPeaks = np.array(peaks[1])
plt.plot(data)
plt.plot(higherPeaks[:,0], higherPeaks[:,1], 'ro')
plt.plot(lowerPeaks[:,0], lowerPeaks[:,1], 'ko')

You can provide a file-like object to the stdin argument of subprocess.call().

The documentation for the Popen object applies here.

To capture the output, you should instead use subprocess.check_output(), which takes similar arguments. From the documentation:

>>> subprocess.check_output(
...     "ls non_existent_file; exit 0",
...     stderr=subprocess.STDOUT,
...     shell=True)
'ls: non_existent_file: No such file or directory\n'

With Ansible 1.9 or later

Ansible uses the become, become_user, and become_method directives to achieve privilege escalation. You can apply them to an entire play or playbook, set them in an included playbook, or set them for a particular task.

- name: checkout repo
  git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
  become: yes
  become_user: some_user

You can use become_with to specify how the privilege escalation is achieved, the default being sudo.

The directive is in effect for the scope of the block in which it is used (examples).

See Hosts and Users for some additional examples and Become (Privilege Escalation) for more detailed documentation.

In addition to the task-scoped become and become_user directives, Ansible 1.9 added some new variables and command line options to set these values for the duration of a play in the absence of explicit directives:

• Command line options for the equivalent become/become_user directives.
• Connection specific variables which can be set per host or group.

As of Ansible 2.0.2.0, the older sudo/sudo_user syntax described below still works, but the deprecation notice states, "This feature will be removed in a future release."

Previous syntax, deprecated as of Ansible 1.9 and scheduled for removal:

- name: checkout repo
  git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
  sudo: yes
  sudo_user: some_user

Your answer is right in the docs:

Body padding required

The fixed navbar will overlay your other content, unless you add padding to the top of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.

body { padding-top: 70px; }

Make sure to include this after the core Bootstrap CSS.

and in the Bootstrap 4 docs...

Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top on the ) to prevent overlap with other elements.

May be am late to answer this question. But still someone may get benefit out of my answer.

I had similar issue and in my case I can not change the directive since, it is a library and change a code of the library is not a good practice. So what I did was use a variable to wait for page load and use ng-if inside my html to wait render the particular element.

In my controller:

$scope.render=false;

//this will fire after load the the page

angular.element(document).ready(function() {
    $scope.render=true;
});

In my html (in my case html component is a canvas)

<canvas ng-if="render"> </canvas>

try setting the attribute for td so:

.topic td{ height: 14px };

Content inside a <div class='html-content'>....</div> can be downloaded as pdf with styles using jspdf & html2canvas.

You need to refer both js libraries,

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
<script type="text/javascript" src="https://html2canvas.hertzen.com/dist/html2canvas.js"></script>

Then call below function,

//Create PDf from HTML...
function CreatePDFfromHTML() {
    var HTML_Width = $(".html-content").width();
    var HTML_Height = $(".html-content").height();
    var top_left_margin = 15;
    var PDF_Width = HTML_Width + (top_left_margin * 2);
    var PDF_Height = (PDF_Width * 1.5) + (top_left_margin * 2);
    var canvas_image_width = HTML_Width;
    var canvas_image_height = HTML_Height;

    var totalPDFPages = Math.ceil(HTML_Height / PDF_Height) - 1;

    html2canvas($(".html-content")[0]).then(function (canvas) {
        var imgData = canvas.toDataURL("image/jpeg", 1.0);
        var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]);
        pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin, canvas_image_width, canvas_image_height);
        for (var i = 1; i <= totalPDFPages; i++) { 
            pdf.addPage(PDF_Width, PDF_Height);
            pdf.addImage(imgData, 'JPG', top_left_margin, -(PDF_Height*i)+(top_left_margin*4),canvas_image_width,canvas_image_height);
        }
        pdf.save("Your_PDF_Name.pdf");
        $(".html-content").hide();
    });
}

May be this will help someone.

You can dispatch a click event, though this is not the same as a real click. For instance, it can't be used to trick a cross-domain iframe document into thinking it was clicked.

All modern browsers support document.elementFromPoint and HTMLElement.prototype.click(), since at least IE 6, Firefox 5, any version of Chrome and probably any version of Safari you're likely to care about. It will even follow links and submit forms:

document.elementFromPoint(x, y).click();

https://developer.mozilla.org/En/DOM:document.elementFromPoint https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click

Using @Tarkus's answer, here are the regexes I used in R:

getColNames <- function(conn, tableName) {
    x <- dbGetQuery( conn, paste0("SELECT sql FROM sqlite_master WHERE tbl_name = '",tableName,"' AND type = 'table'") )[1,1]
    x <- str_split(x,"\\n")[[1]][-1]
    x <- sub("[()]","",x)
    res <- gsub( '"',"",str_extract( x[1], '".+"' ) )
    x <- x[-1]
    x <- x[-length(x)]
    res <- c( res, gsub( "\\t", "", str_extract( x, "\\t[0-9a-zA-Z_]+" ) ) )
    res
}

Code is somewhat sloppy, but it appears to work.

To add to add to the previous answer, there is even a fourth way that can be used

import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)

I solved it with my own function. If you want to update specified field in document you need to address it clearly.

Example:

{
    _id : ...,
    some_key: { 
        param1 : "val1",
        param2 : "val2",
        param3 : "val3"
    }
}

If you want to update param2 only, it's wrong to do:

db.collection.update(  { _id:...} , { $set: { some_key : new_info  } }  //WRONG

You must use:

db.collection.update(  { _id:...} , { $set: { some_key.param2 : new_info  } } 

So i wrote a function something like that:

function _update($id, $data, $options=array()){

    $temp = array();
    foreach($data as $key => $value)
    {
        $temp["some_key.".$key] = $value;
    } 

    $collection->update(
        array('_id' => $id),
        array('$set' => $temp)
    );

}

_update('1', array('param2' => 'some data'));
