The Pythonic way of summing an array is using sum. For other purposes, you can sometimes use some combination of reduce (from the functools module) and the operator module, e.g.:

def product(xs):
    return reduce(operator.mul, xs, 1)

Be aware that reduce is actually a foldl, in Haskell terms. There is no special syntax to perform folds, there's no builtin foldr, and actually using reduce with non-associative operators is considered bad style.

Using higher-order functions is quite pythonic; it makes good use of Python's principle that everything is an object, including functions and classes. You are right that lambdas are frowned upon by some Pythonistas, but mostly because they tend not to be very readable when they get complex.

When you create a new CMS block named block_identifier from the admin panel you can use the following code to call it from your .phtml file:

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block_identifier')->toHtml(); 
?> 

Then clear the cache and reload your browser.

I'm surprised nobody mentioned this. You can tether via Bluetooth, and separate them by ten+ meters(or less with obstacles). You've got a real bad connection. No microwave, no elevator, no software needed.

This is arguably not the best way for most circumstances, but it's not been mentioned yet so perhaps it will help someone.

1. Bind mount host volume

   Host folder FOOBAR is mounted in container /volume/FOOBAR

2. Modify your container's startup script to find GID of the volume you're interested in

   $ TARGET_GID=$(stat -c "%g" /volume/FOOBAR)

3. Ensure your user belongs to a group with this GID (you may have to create a new group). For this example I'll pretend my software runs as the nobody user when inside the container, so I want to ensure nobody belongs to a group with a group id equal to TARGET_GID

  EXISTS=$(cat /etc/group | grep $TARGET_GID | wc -l)

  # Create new group using target GID and add nobody user
  if [ $EXISTS == "0" ]; then
    groupadd -g $TARGET_GID tempgroup
    usermod -a -G tempgroup nobody
  else
    # GID exists, find group name and add
    GROUP=$(getent group $TARGET_GID | cut -d: -f1)
    usermod -a -G $GROUP nobody
  fi

I like this because I can easily modify group permissions on my host volumes and know that those updated permissions apply inside the docker container. This happens without any permission or ownership modifications to my host folders/files, which makes me happy.

I don't like this because it assumes there's no danger in adding yourself to an arbitrary groups inside the container that happen to be using a GID you want. It cannot be used with a USER clause in a Dockerfile (unless that user has root privileges I suppose). Also, it screams hack job ;-)

If you want to be hardcore you can obviously extend this in many ways - e.g. search for all groups on any subfiles, multiple volumes, etc.

If you are using curl on Windows:

curl -H "Content-Type: application/xml" -d "<?xml version="""1.0""" encoding="""UTF-8""" standalone="""yes"""?><message><sender>Me</sender><content>Hello!</content></message>" http://localhost:8080/webapp/rest/hello

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

This might be because of the transitive dependencies.

Try to add/ remove the scope from the JSTL library.

This worked for me!

In app.component.html:

 <select type="number" [(ngModel)]="selectedLevel">
          <option *ngFor="let level of levels" [ngValue]="level">{{level.name}}</option>
        </select>

And app.component.ts:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  levelNum:number;
  levels:Array<Object> = [
      {num: 0, name: "AA"},
      {num: 1, name: "BB"}
  ];

  toNumber(){
    this.levelNum = +this.levelNum;
    console.log(this.levelNum);
  }

  selectedLevel = this.levels[0];

  selectedLevelCustomCompare = {num: 1, name: "BB"}

  compareFn(a, b) {
    console.log(a, b, a && b && a.num == b.num);
    return a && b && a.num == b.num;
  }
}

here is another t-sql UDF

CREATE FUNCTION dbo.Format(@num int)
returns varChar(30)
As
Begin
Declare @out varChar(30) = ''

  while @num > 0 Begin
      Set @out = str(@num % 1000, 3, 0) + Coalesce(','+@out, '')
      Set @num = @num / 1000
  End
  Return @out
End

You are setting the extra with an array. You are then trying to get a single int.

Your code should be:

int[] arrayB = extras.getIntArray("numbers");

// Get current date/time in milliseconds.
#include "boost/date_time/posix_time/posix_time.hpp"
namespace pt = boost::posix_time;

int main()
{
     pt::ptime current_date_microseconds = pt::microsec_clock::local_time();

    long milliseconds = current_date_microseconds.time_of_day().total_milliseconds();

    pt::time_duration current_time_milliseconds = pt::milliseconds(milliseconds);

    pt::ptime current_date_milliseconds(current_date_microseconds.date(), 
                                        current_time_milliseconds);

    std::cout << "Microseconds: " << current_date_microseconds 
              << " Milliseconds: " << current_date_milliseconds << std::endl;

    // Microseconds: 2013-Jul-12 13:37:51.699548 Milliseconds: 2013-Jul-12 13:37:51.699000
}

With deployments that have stateful sets (or services, jobs, etc.) you can use this command:

This command terminates anything that runs in the specified <NAMESPACE>

kubectl -n <NAMESPACE> delete replicasets,deployments,jobs,service,pods,statefulsets --all

And forceful

kubectl -n <NAMESPACE> delete replicasets,deployments,jobs,service,pods,statefulsets --all --cascade=true --grace-period=0 --force

This is just some additional information that might help anyone. I want to make it abundantly clear that what I am describing here is possibly:

• A. not 100% correct and
• B. not safe in terms of network security.

I am not a DBA, but every time I find myself setting up a SQL Server (Express or Full) for testing or what not I run into the connectivity issue. The solution I am describing is more for the person who is just trying to get their job done - consult someone who is knowledgeable in this field when setting up a production server.

For SQL Server 2008 R2 this is what I end up doing:

1. Make sure everything is squared away like in this tutorial which is the same tutorial posted above as a solution by "Dani" as the selected answer to this question.
2. Check and/or set, your firewall settings for the computer that is hosting the SQL Server. If you are using a Windows Server 2008 R2 then use the Server Manager, go to Configuration and then look at "Windows Firewall with Advanced Security". If you are using Windows 7 then go to Control Panel and search for "Firewall" click on "Allow a program through Windows Firewall".
   • Create an inbound rule for port TCP 1433 - allow the connection
   • Create an outbound rule for port TCP 1433 - allow the connection
3. When you are finished with the firewall settings you are going to want to check one more thing. Open up the "SQL Server Configuration Manager" locate: SQL Server Network Configuration - Protocols for SQLEXPRESS (or equivalent) - TCP/IP
   • Double click on TCP/IP
   • Click on the IP Addresses tab
   • Under IP1 set the TCP Port to 1433 if it hasn't been already
   • Under IP All set the TCP Port to 1433 if it hasn't been already
4. Restart SQL Server and SQL Browser (do both just to be on the safe side)

Usually after I do what I mentioned above I don't have a problem anymore. Here is a screenshot of what to look for - for that last step:

Again, if someone with more information about this topic sees a red flag please correct me.

If you want to stash untracked files, but keep indexed files (the ones you're about to commit for example), just add -k (keep index) option to the -u

git stash -u -k

Perhaps your Apache is bounded to localhost only. Look in your apache configuration file for:

Listen 127.0.0.1:80

If you found it, replace it for:

Listen 80

You could also use re.search depending on how you want it to match.

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

You're asking the wrong question. The codebehind (controller) has nothing to do with what the frontend does. In fact, that's the strength of MVC -- you separate the code/concept from the view.

If you want an action to open in a new window, then links to that action need to tell the browser to open a new window when clicked.

A pseudo example: <a href="NewWindow" target="_new">Click Me</a>

And that's all there is to it. Set the target of links to that action.

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

Did the following for a spring application running static, rest and websocket content.

The Apache is used as Proxy and SSL Endpoint for the following URIs:

• /app → static content
• /api → REST API
• /api/ws → websocket

Apache configuration

<VirtualHost *:80>
    ServerName xxx.xxx.xxx    

    ProxyRequests Off
    ProxyVia Off
    ProxyPreserveHost On

    <Proxy *>
         Require all granted
    </Proxy>

    RewriteEngine On

    # websocket 
    RewriteCond %{HTTP:Upgrade}         =websocket                      [NC]
    RewriteRule ^/api/ws/(.*)           ws://localhost:8080/api/ws/$1   [P,L]

    # rest
    ProxyPass /api http://localhost:8080/api
    ProxyPassReverse /api http://localhost:8080/api

    # static content    
    ProxyPass /app http://localhost:8080/app
    ProxyPassReverse /app http://localhost:8080/app 
</VirtualHost>

I use the same vHost config for the SSL configuration, no need to change anything proxy related.

<ui:include>

Most basic way is <ui:include>. The included content must be placed inside <ui:composition>.

Kickoff example of the master page /page.xhtml:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title>Include demo</title>
    </h:head>
    <h:body>
        <h1>Master page</h1>
        <p>Master page blah blah lorem ipsum</p>
        <ui:include src="/WEB-INF/include.xhtml" />
    </h:body>
</html>

The include page /WEB-INF/include.xhtml (yes, this is the file in its entirety, any tags outside <ui:composition> are unnecessary as they are ignored by Facelets anyway):

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h2>Include page</h2>
    <p>Include page blah blah lorem ipsum</p>
</ui:composition>
  

This needs to be opened by /page.xhtml. Do note that you don't need to repeat <html>, <h:head> and <h:body> inside the include file as that would otherwise result in invalid HTML.

You can use a dynamic EL expression in <ui:include src>. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

<ui:define>/<ui:insert>

A more advanced way of including is templating. This includes basically the other way round. The master template page should use <ui:insert> to declare places to insert defined template content. The template client page which is using the master template page should use <ui:define> to define the template content which is to be inserted.

Master template page /WEB-INF/template.xhtml (as a design hint: the header, menu and footer can in turn even be <ui:include> files):

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title><ui:insert name="title">Default title</ui:insert></title>
    </h:head>
    <h:body>
        <div id="header">Header</div>
        <div id="menu">Menu</div>
        <div id="content"><ui:insert name="content">Default content</ui:insert></div>
        <div id="footer">Footer</div>
    </h:body>
</html>

Template client page /page.xhtml (note the template attribute; also here, this is the file in its entirety):

<ui:composition template="/WEB-INF/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

    <ui:define name="title">
        New page title here
    </ui:define>

    <ui:define name="content">
        <h1>New content here</h1>
        <p>Blah blah</p>
    </ui:define>
</ui:composition>

This needs to be opened by /page.xhtml. If there is no <ui:define>, then the default content inside <ui:insert> will be displayed instead, if any.

<ui:param>

You can pass parameters to <ui:include> or <ui:composition template> by <ui:param>.

<ui:include ...>
    <ui:param name="foo" value="#{bean.foo}" />
</ui:include>

<ui:composition template="...">
    <ui:param name="foo" value="#{bean.foo}" />
    ...
</ui:composition >

Inside the include/template file, it'll be available as #{foo}. In case you need to pass "many" parameters to <ui:include>, then you'd better consider registering the include file as a tagfile, so that you can ultimately use it like so <my:tagname foo="#{bean.foo}">. See also When to use <ui:include>, tag files, composite components and/or custom components?

You can even pass whole beans, methods and parameters via <ui:param>. See also JSF 2: how to pass an action including an argument to be invoked to a Facelets sub view (using ui:include and ui:param)?

Design hints

The files which aren't supposed to be publicly accessible by just entering/guessing its URL, need to be placed in /WEB-INF folder, like as the include file and the template file in above example. See also Which XHTML files do I need to put in /WEB-INF and which not?

There doesn't need to be any markup (HTML code) outside <ui:composition> and <ui:define>. You can put any, but they will be ignored by Facelets. Putting markup in there is only useful for web designers. See also Is there a way to run a JSF page without building the whole project?

The HTML5 doctype is the recommended doctype these days, "in spite of" that it's a XHTML file. You should see XHTML as a language which allows you to produce HTML output using a XML based tool. See also Is it possible to use JSF+Facelets with HTML 4/5? and JavaServer Faces 2.2 and HTML5 support, why is XHTML still being used.

CSS/JS/image files can be included as dynamically relocatable/localized/versioned resources. See also How to reference CSS / JS / image resource in Facelets template?

You can put Facelets files in a reusable JAR file. See also Structure for multiple JSF projects with shared code.

For real world examples of advanced Facelets templating, check the src/main/webapp folder of Java EE Kickoff App source code and OmniFaces showcase site source code.

If I'm not mistaken:

var jq = $.noConflict();

then you can call jquery function with jq.(whatever).

jq('#selector');

I just put the content in the question in a file called test.php and ran php test.php. (In the folder where the test.php is.)

$ php foo.php

Try this:

<?php 
/*

get_header();
echo do_shortcode('[CONTACT-US-FORM]'); 
?>

You can use the Search & Replace feature with this regex ^([\w\d\_\.\s\-]*)$ to find text and the replaced text is "$1".

    {
        List<Order> orders = new List<Order>();

        {
            orders = (from o in db.Orders
                      orderby o.Date descending //use orderby, otherwise Skip will throw an error

Bonus

Do above first, then perhaps use this!

Since this question is about (view) models, I'm going to give away a little solution for you that will not only be useful for paging, but for the rest of your application if you want to keep your entities separate, only used in the repository, and have the rest of the application deal with models (which can be used as view models).

Repository

In your order repository (in my case), add a static method to convert a model:

public static OrderModel ConvertToModel(Order entity)
{
    if (entity == null) return null;
    OrderModel model = new OrderModel
    {
        ContactId = entity.contactId,
        OrderId = entity.orderId,
    }
    return model;
}

Below your repository class, add this:

public static partial class Ex
{
    public static IEnumerable<OrderModel> SelectOrderModel(this IEnumerable<Order> source)
    {
        bool includeRelations = source.GetType() != typeof(DbQuery<Order>);
        return source.Select(x => new OrderModel
        {
            OrderId = x.orderId,
            //example use ConvertToModel of some other repository
            BillingAddress = includeRelations ? AddressRepository.ConvertToModel(x.BillingAddress) : null,
            //example use another extension of some other repository
            Shipments = includeRelations && x.Shipments != null ? x.Shipments.SelectShipmentModel() : null
        });
    }
}

And then in your GetOrderPage method:

    public IEnumerable<OrderModel> GetOrderPage(int page, int itemsPerPage, string searchString, string sortOrder, int? partnerId,
        out int totalCount)
    {
        IQueryable<Order> query = DbContext.Orders; //get queryable from db
        .....//do your filtering, sorting, paging (do not use .ToList() yet)

        return queryOrders.SelectOrderModel().AsEnumerable();
        //or, if you want to include relations
        return queryOrders.Include(x => x.BillingAddress).ToList().SelectOrderModel();
        //notice difference, first ToList(), then SelectOrderModel().
    }

Let me explain:

The static ConvertToModel method can be accessed by any other repository, as used above, I use ConvertToModel from some AddressRepository.

The extension class/method lets you convert an entity to a model. This can be IQueryable or any other list, collection.

Now here comes the magic: If you have executed the query BEFORE calling SelectOrderModel() extension, includeRelations inside the extension will be true because the source is NOT a database query type (not an linq-to-sql IQueryable). When this is true, the extension can call other methods/extensions throughout your application for converting models.

Now on the other side: You can first execute the extension and then continue doing LINQ filtering. The filtering will happen in the database eventually, because you did not do a .ToList() yet, the extension is just an layer of dealing with your queries. Linq-to-sql will eventually know what filtering to apply in the Database. The inlcudeRelations will be false so that it doesn't call other c# methods that SQL doesn't understand.

It looks complicated at first, extensions might be something new, but it's really useful. Eventually when you have set this up for all repositories, simply an .Include() extra will load the relations.

If you only want to change the progress bar color, you can simply use a color filter in your Activity's onCreate() method:

ProgressBar progressbar = (ProgressBar) findViewById(R.id.progressbar);
int color = 0xFF00FF00;
progressbar.getIndeterminateDrawable().setColorFilter(color, PorterDuff.Mode.SRC_IN);
progressbar.getProgressDrawable().setColorFilter(color, PorterDuff.Mode.SRC_IN);

Idea from here.

You only need to do this for pre-lollipop versions. On Lollipop you can use the colorAccent style attribute.

                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

If you are getting the output Optional(5) when trying to print the value of 5 in an optional Int or String, you should unwrap the value first:

if let value = text {
    print(value)
}

Now you've got the value without the "Optional" string that Swift adds when the value is not unwrapped before.

I'm not sure why you "can't login to the Apple Developer Forums", but (without violating the NDA) you can also hide your statusBar through Xcode. It's a general setting on your application target.

Just use the style float: left in this way:

<p style="float: left"> Lorem Ipsum </p> 
<form style="float: left">
   <input  type='submit'/>
</form>
<p style="float: left"> Lorem Ipsum </p>

I start applications that I want to run persistently or at least semi-permanently via screen -dmS NAME /path/to/script. As far as I am informed this is the most elegant solution.

I had same issue in Angular7 when I create dynamic components. There are two components(TreatListComponent, MyTreatComponent) that needs to be loaded dynamically. I just added entryComponents array in to my app.module.ts file.

    entryComponents: [
    TreatListComponent,
    MyTreatComponent
  ],

Here is another way...

It adds "others" to the enum definition of the column "rtipo" of the table "firmas".

set @new_enum = 'others';
set @table_name = 'firmas';
set @column_name = 'rtipo';
select column_type into @tmp from information_schema.columns 
  where table_name = @table_name and column_name=@column_name;
set @tmp = insert(@tmp, instr(@tmp,')'), 0, concat(',\'', @new_enum, '\'') );
set @tmp = concat('alter table ', @table_name, ' modify ', @column_name, ' ', @tmp);
prepare stmt from @tmp;
execute stmt;
deallocate prepare stmt;

Our version of Oracle is running on Red Hat Enterprise Linux. We experimented with several different types of group permissions to no avail. The /defaultdir directory had a group that was a secondary group for the oracle user. When we updated the /defaultdir directory to have a group of "oinstall" (oracle's primary group), I was able to select from the external tables underneath that directory with no problem.

So, for others that come along and might have this issue, make the directory have oracle's primary group as the group and it might resolve it for you as it did us. We were able to set the permissions to 770 on the directory and files and selecting on the external tables works fine now.

I had the same use case, You can change your method defination in the following way :

@RequestMapping(value = "/saveFruits", method = RequestMethod.POST, 
    consumes = "application/json")
@ResponseBody
public ResultObject saveFruits(@RequestBody Map<String,List<String>> fruits) {
    ..
}

The only problem is it accepts any key in place of "fruits" but You can easily get rid of a wrapper if it is not big functionality.

If you have installed openssl, you can use:

echo -n "foobar" | openssl dgst -sha256

For other algorithms you can replace -sha256 with -md4, -md5, -ripemd160, -sha, -sha1, -sha224, -sha384, -sha512 or -whirlpool.

For the original see doublep answer:

Foo[] a = x.toArray(new Foo[x.size()]);

As for the update:

int i = 0;
Bar[] bars = new Bar[fooCollection.size()];
for( Foo foo : fooCollection ) { // where fooCollection is Collection<Foo>
    bars[i++] = new Bar(foo);
}    

This is the idiom I've always used to get a modified copy of a string without changing the original:

(my $newstring = $oldstring) =~ s/foo/bar/g;

In perl 5.14.0 or later, you can use the new /r non-destructive substitution modifier:

my $newstring = $oldstring =~ s/foo/bar/gr; 

NOTE:
The above solutions work without g too. They also work with any other modifiers.

Similar to Underscore library there is another library called as 'lodash' that has one method "orderBy" which takes in the parameter to determine in which order to sort it. You can use it like

_.orderBy('collection', 'propertyName', 'desc')

For some reason, it's not documented on the website docs.

If you either want the string or an empty string in case something is null, without anything can break:

using (var cmd = new OdbcCommand(cmdText, connection))
{
    var result = string.Empty;
    var scalar = cmd.ExecuteScalar();
    if (scalar != DBNull.Value) // Case where the DB value is null
    {
        result = Convert.ToString(scalar); // Case where the query doesn't return any rows. 
        // Note: Convert.ToString() returns an empty string if the object is null. 
        //       It doesn't break, like scalar.ToString() would have.
    }
    return result;
}

Its working in Safari browser.

html,
body {
  overflow: hidden;
  position: fixed
}

Declare this

[DllImport("user32")]
private static extern bool SetForegroundWindow(IntPtr hwnd);
[DllImport("user32")]
private static extern bool ShowWindowAsync(IntPtr hwnd, int a);

And put this inside your function (note that "checkInstalled" is optional, but if you'll use it, you have to implement it)

if (ckeckInstalled("example"))
{
    int count = Process.GetProcessesByName("example").Count();
    if (count < 1)
        Process.Start("example.exe");
    else
    {
        var proc = Process.GetProcessesByName("example").FirstOrDefault();
        if (proc != null && proc.MainWindowHandle != IntPtr.Zero)
        {
            SetForegroundWindow(proc.MainWindowHandle);
            ShowWindowAsync(proc.MainWindowHandle, 3);
        }
    }
}

NOTE: I'm not sure if this works when more than one instance of the .exe is running.

Yet another variant:

Date.prototype.isPrototypeOf(myDateObject)

The Java keyword list specifies the goto keyword, but it is marked as "not used".

It was in the original JVM (see answer by @VitaliiFedorenko), but then removed. It was probably kept as a reserved keyword in case it were to be added to a later version of Java.

If goto was not on the list, and it gets added to the language later on, existing code that used the word goto as an identifier (variable name, method name, etc...) would break. But because goto is a keyword, such code will not even compile in the present, and it remains possible to make it actually do something later on, without breaking existing code.

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

for 1 dimensional array

int[] listItems = new int[] {2,4,8};
int length = listItems.Length;

for multidimensional array

int length = listItems.Rank;

To get the size of 1 dimension

int length =  listItems.GetLength(0);

As far as aspect oriented logging is concerned I was recommended PostSharp on another SO question -

Aspect Oriented Logging with Unity\T4\anything else

The link provided in the answer is worth visiting if you are evaluating logging frameworks.

':'.join(x.encode('hex') for x in 'Hello World!')

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

It will store value of number of characters printed so far in that printf() function.

Example:

int a;
printf("Hello World %n \n", &a);
printf("Characters printed so far = %d",a);

The output of this program will be

Hello World
Characters printed so far = 12

When passing by value:

void func(Object o);

and then calling

func(a);

you will construct an Object on the stack, and within the implementation of func it will be referenced by o. This might still be a shallow copy (the internals of a and o might point to the same data), so a might be changed. However if o is a deep copy of a, then a will not change.

When passing by reference:

void func2(Object& o);

and then calling

func2(a);

you will only be giving a new way to reference a. "a" and "o" are two names for the same object. Changing o inside func2 will make those changes visible to the caller, who knows the object by the name "a".

A real edge case is where you have used an MySQL tool, (Sequel Pro in my case) to rename a database. Then created a database with the same name.

This kept foreign key constraints to the same database name, so the renamed database (e.g. my_db_renamed) had foreign key constraints in the newly created database (my_db)

Not sure if this is a bug in Sequel Pro, or if some use case requires this behaviour, but it cost me best part of a morning :/

Mac OSX only

An easier way to get going (assuming you already have homebrew installed, which you should, if not, go do that first and let homebrew make your life better) is to just run the following command:

brew install chromedriver

That should put the chromedriver in your path and you should be all set.

you could try

if (isValid) {
    document.getElementById("endTimeLabel").style.display = "none";
}else {
    document.getElementById("endTimeLabel").style.display = "block";
}

alone those lines

I am not very good in grep. But your problem can be solved using AWK command. Just see

awk '/select/,/from/' *.sql

The above code will result from first occurence of select till first sequence of from. Now you need to verify whether returned statements are having customername or not. For this you can pipe the result. And can use awk or grep again.

If any body wants to convert list of custom class objects instead of list of string then override the ToString method of your class with csv row representation of your class.

Public Class MyClass{
   public int Id{get;set;}
   public String PropertyA{get;set;}
   public override string ToString()
   {
     return this.Id+ "," + this.PropertyA;
   }
}

Then following code can be used to convert this class list to CSV with header column

string csvHeaderRow = String.Join(",", typeof(MyClass).GetProperties(BindingFlags.Public | BindingFlags.Instance).Select(x => x.Name).ToArray<string>()) + Environment.NewLine;
string csv= csvHeaderRow + String.Join(Environment.NewLine, MyClass.Select(x => x.ToString()).ToArray());

Adding another simple alternative that is quite elegant in my opinion.

Your plot:

plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")

Legend:

legend("bottomright", c("group A", "group B"), pch=c(1,2), lty=c(1,2),
       inset=c(0,1), xpd=TRUE, horiz=TRUE, bty="n"
       )

Result:

Here only the second line of the legend was added to your example. In turn:

• inset=c(0,1) - moves the legend by fraction of plot region in (x,y) directions. In this case the legend is at "bottomright" position. It is moved by 0 plotting regions in x direction (so stays at "right") and by 1 plotting region in y direction (from bottom to top). And it so happens that it appears right above the plot.
• xpd=TRUE - let's the legend appear outside of plotting region.
• horiz=TRUE - instructs to produce a horizontal legend.
• bty="n" - a style detail to get rid of legend bounding box.

Same applies when adding legend to the side:

par(mar=c(5,4,2,6))
plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")

legend("topleft", c("group A", "group B"), pch=c(1,2), lty=c(1,2),
       inset=c(1,0), xpd=TRUE, bty="n"
       )

Here we simply adjusted legend positions and added additional margin space to the right side of the plot. Result:

class async_file_get_contents extends Thread{
    public $ret;
    public $url;
    public $finished;
        public function __construct($url) {
        $this->finished=false;
        $this->url=$url;
    }
        public function run() {
        $this->ret=file_get_contents($this->url);
        $this->finished=true;
    }
}
$afgc=new async_file_get_contents("http://example.org/file.ext");

The assignment operator has lower precedence than &&, so your condition is equivalent to:

if ((match == 0 && k) = m)

But the left-hand side of this is an rvalue, namely the boolean resulting from the evaluation of the sub­expression match == 0 && k, so you cannot assign to it.

By contrast, comparison has higher precedence, so match == 0 && k == m is equivalent to:

if ((match == 0) && (k == m))

I have posted a new post about how to build an Android NDK application with OpenCV included using Android Studio and Gradle. More information can be seen here, I have summarized two methods:

(1) run ndk-build within Gradle task

sourceSets.main.jni.srcDirs = []

task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
    ndkDir = project.plugins.findPlugin('com.android.application').getNdkFolder()
    commandLine "$ndkDir/ndk-build",
            'NDK_PROJECT_PATH=build/intermediates/ndk',
            'NDK_LIBS_OUT=src/main/jniLibs',
            'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
            'NDK_APPLICATION_MK=src/main/jni/Application.mk'
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}

(2) run ndk-build with an external tool

Parameters: NDK_PROJECT_PATH=$ModuleFileDir$/build/intermediates/ndk NDK_LIBS_OUT=$ModuleFileDir$/src/main/jniLibs NDK_APPLICATION_MK=$ModuleFileDir$/src/main/jni/Application.mk APP_BUILD_SCRIPT=$ModuleFileDir$/src/main/jni/Android.mk V=1

Source article: Java: Calling super()

Yes. super(...) will invoke the constructor of the super-class.

Illustration:

Stand alone example:

class Animal {
    public Animal(String arg) {
        System.out.println("Constructing an animal: " + arg);
    }
}

class Dog extends Animal {
    public Dog() {
        super("From Dog constructor");
        System.out.println("Constructing a dog.");
    }
}

public class Test {
    public static void main(String[] a) {
        new Dog();
    }
}

Prints:

Constructing an animal: From Dog constructor
Constructing a dog.

At the present time, Intel graphics chips do not support CUDA. It is possible that, in the nearest future, these chips will support OpenCL (which is a standard that is very similar to CUDA), but this is not guaranteed and their current drivers do not support OpenCL either. (There is an Intel OpenCL SDK available, but, at the present time, it does not give you access to the GPU.)

Newest Intel processors (Sandy Bridge) have a GPU integrated into the CPU core. Your processor may be a previous-generation version, in which case "Intel(HD) graphics" is an independent chip.

I am assuming that you are making a quiz kind of application. For this kind of application I have written a function which is as follows:

def shuffle(q):
"""
The input of the function will 
be the dictionary of the question
and answers. The output will
be a random question with answer
"""
selected_keys = []
i = 0
while i < len(q):
    current_selection = random.choice(q.keys())
    if current_selection not in selected_keys:
        selected_keys.append(current_selection)
        i = i+1
        print(current_selection+'? '+str(q[current_selection]))

If I will give the input of questions = {'VENEZUELA':'CARACAS', 'CANADA':'TORONTO'} and call the function shuffle(questions) Then the output will be as follows:

VENEZUELA? CARACAS
CANADA? TORONTO

You can extend this further more by shuffling the options also

Swift 5.0

// Standard State
myButton.setTitle("Title", for: .normal)

The answer is YES, but shouldn't use 'Background Fetch' or 'Remote notification'. PushKit is the answer you desire.

In summary, PushKit, the new framework in ios 8, is the new push notification mechanism which can silently launch your app into the background with no visual alert prompt even your app was killed by swiping out from app switcher, amazingly you even cannot see it from app switcher.

PushKit reference from Apple:

The PushKit framework provides the classes for your iOS apps to receive pushes from remote servers. Pushes can be of one of two types: standard and VoIP. Standard pushes can deliver notifications just as in previous versions of iOS. VoIP pushes provide additional functionality on top of the standard push that is needed to VoIP apps to perform on-demand processing of the push before displaying a notification to the user.

To deploy this new feature, please refer to this tutorial: https://zeropush.com/guide/guide-to-pushkit-and-voip - I've tested it on my device and it works as expected.

In order to match the vector lenght and angle with the x,y coordinates of the plot, you can use to following options to plt.quiver:

plt.figure(figsize=(5,2), dpi=100)

plt.xlim(0,250)
plt.ylim(0,100)

Well you would need to get a file with JFileChooser and then read through the lines of the file using a scanner and the hasNext() function

http://docs.oracle.com/javase/7/docs/api/javax/swing/JFileChooser.html

once you do that you can save the line into a variable and manipulate the contents.

I am adding my solution to this problem.

I don't want to use image and validator will punish you for using negative values in CSS, so I go this way:

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

li          { padding-left:0.75em; position:relative; }

li:before       { content:"•"; color:#e60000; position:absolute; left:0em; }

Try your regex with a tool like http://jsregex.com/ (There is many) or better, a unit test.

For a naive validation:

function validateDate(testdate) {
    var date_regex = /^\d{2}\/\d{2}\/\d{4}$/ ;
    return date_regex.test(testdate);
}

In your case, to validate (MM/DD/YYYY), with a year between 1900 and 2099, I'll write it like that:

function validateDate(testdate) {
    var date_regex = /^(0[1-9]|1[0-2])\/(0[1-9]|1\d|2\d|3[01])\/(19|20)\d{2}$/ ;
    return date_regex.test(testdate);
}

}

Let's say N = 5 and your model is Message, you can do something like this:

Message.order(id: :asc).from(Message.all.order(id: :desc).limit(5), :messages)

Look at the sql:

SELECT "messages".* FROM (
  SELECT  "messages".* FROM "messages"  ORDER BY "messages"."created_at" DESC LIMIT 5
) messages  ORDER BY "messages"."created_at" ASC

The key is the subselect. First we need to define what are the last messages we want and then we have to order them in ascending order.

You could put \s* inbetween every character in your search string so if you were looking for cat you would use c\s*a\s*t\s*s\s*s

It's long but you could build the string dynamically of course.

You can see it working here: http://www.rubular.com/r/zzWwvppSpE

This problem normally appears while copy pasting the tag lib URL from the internet. Usually the quotes "" in which the URL http://www.springframework.org/tags is embedded might not be correct. Try removing quotes and type them manually. This resolved the issue for me.

Try:

s = filter(str.isalnum, s)

in Python3:

s = ''.join(filter(str.isalnum, s))

Edit: realized that the OP wants to replace non-chars with '*'. My answer does not fit

    private void button1_Click(object sender, EventArgs e)
    {
        long myTicks = 633896886277130000;
        DateTime dtime = new DateTime(myTicks);
        MessageBox.Show(dtime.ToString("MMMM d, yyyy"));
    }

Is that what you need?

I don't see how that format is necessarily easy to work with in SQL queries, though.

I was faced with something similar recently and solved it by catching the error to find out if it's a Mongoose ObjectId error.

app.get("/:userId", (req, res, next) => {
    try {
        // query and other code here
    } catch (err) {
        if (err.kind === "ObjectId") {
            return res.status(404).json({
                errors: [
                    {
                        msg: "User not found",
                        status: "404",
                    },
                ],
            });
        }
        next(err);
    }
});

Try this:

In the IIS Manager right click on Web sites, chose New, then Web site...

This way you can recreate the Default Web Site.

After these steps restart IIS: Right click on local computer, All Tasks, Restart IIS...

locale command with no arguments will print the values of all of the relevant environment variables except for LANGUAGE.

For current encoding:

locale charmap

For available locales:

locale -a

For available encodings:

locale -m

To further expand on BIGNUM's post - Ideally you want a solution that will simulate the conditions you will see in production and modifying your code won't do that and could be dangerous if you forget to take the code out before you deploy it.

You will need a self-signed certificate of some sort. If you know what you're doing you can use the binary BIGNUM posted, but if not you can go hunting for the certificate. If you're using IIS Express you will have one of these already, you'll just have to find it. Open Firefox or whatever browser you like and go to your dev website. You should be able to view the certificate information from the URL bar and depending on your browser you should be able to export the certificate to a file.

Next, open MMC.exe, and add the Certificate snap-in. Import your certificate file into the Trusted Root Certificate Authorities store and that's all you should need. It's important to make sure it goes into that store and not some other store like 'Personal'. If you're unfamiliar with MMC or certificates, there are numerous websites with information how to do this.

Now, your computer as a whole will implicitly trust any certificates that it has generated itself and you won't need to add code to handle this specially. When you move to production it will continue to work provided you have a proper valid certificate installed there. Don't do this on a production server - that would be bad and it won't work for any other clients other than those on the server itself.

Agree with @Tillito, however in most cases it will foul SQL optimizer and it will not use right indexes.

It may be obvious for somebody, but I burned hours solving performance issues using Tillito solution. Lets say you have the table:

 Create table OrderDetail
    (  
       Id int primary key,
       CustomerId int references Customer(Id),
       Amount decimal default(0)
    );
 Create index ix_customer on OrderDetail(CustomerId);

and your view is something like this

 Create view CustomerView
    As
      Select 
          IsNull(CustomerId, -1) as CustomerId, -- forcing EF to use it as key
          Sum(Amount) as Amount
      From OrderDetail
      Group by CustomerId

Sql optimizer will not use index ix_customer and it will perform table scan on primary index, but if instead of:

Group by CustomerId

you use

Group by IsNull(CustomerId, -1)

it will make MS SQL (at least 2008) include right index into plan.

You can only Extend a single class. And implement Interfaces from many sources.

Extending multiple classes is not available. The only solution I can think of is not inheriting either class but instead having an internal variable of each class and doing more of a proxy by redirecting the requests to your object to the object that you want them to go to.

 public class CustomActivity extends Activity {

     private AnotherClass mClass;

     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         mClass = new AnotherClass(this);
     }

     //Implement each method you want to use.
     public String getInfoFromOtherClass()
     {
        return mClass.getInfoFromOtherClass();
     }
 }

this is the best solution I have come up with. You can get the functionality from both classes and Still only actually be of one class type.

The drawback is that you cannot fit into the Mold of the Internal class using a cast.

In the newer version of datatables (version 1.10.7) it seems things have changed. The way to prevent DataTables from automatically sorting by the first column is to set the order option to an empty array.

You just need to add the following parameter to the DataTables options:

"order": [] 

Set up your DataTable as follows in order to override the default setting:

$('#example').dataTable( {
    "order": [],
    // Your other options here...
} );

That will override the default setting of "order": [[ 0, 'asc' ]].

You can find more details regarding the order option here: https://datatables.net/reference/option/order

A simple solution with acceptable outcome:

<input type="file" class="form-control">

And the style:

input[type=file].form-control {
    height: auto;
}

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

Or visit my codepen example :

Follow these instructions,

1. First make sure you have notepad++ installed on your system and that it is the default programme to open .txt files.

2. Then Install gitpad on your system. Note the last I checked the download link was broken, so download it from here as explained.

Then while committing you should see your favorite text editor popping up.

To create a test case template:

"New" -> "JUnit Test Case" -> Select "Class under test" -> Select "Available methods". I think the wizard is quite easy for you.

You need to use the square brackets notation to have values sent as an array:

<form method='post' id='userform' action='thisform.php'>
<tr>
    <td>Trouble Type</td>
    <td>
    <input type='checkbox' name='checkboxvar[]' value='Option One'>1<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Two'>2<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Three'>3
    </td>
</tr>
</table>
<input type='submit' class='buttons'>
</form>

Please note though, that only the values of only checked checkboxes will be sent.

String start_dt = "2011-01-31";

DateFormat parser = new SimpleDateFormat("yyyy-MM-dd"); 
Date date = (Date) parser.parse(start_dt);

DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy"); 
System.out.println(formatter.format(date));

Prints: 01-31-2011

You are trying to run bash, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d, but you can do this by adding -it to the command line, which ensures that the container has a valid tty associated with it and that stdin remains connected:

docker run -it -d -p 52022:22 basickarl/docker-git-test

You would more commonly run some sort of long-lived non-interactive process (like sshd, or a web server, or a database server, or a process manager like systemd or supervisor) when starting detached containers.

If you are trying to run a service like sshd, you cannot simply run service ssh start. This will -- depending on the distribution you're running inside your container -- do one of two things:

• It will try to contact a process manager like systemd or upstart to start the service. Because there is no service manager running, this will fail.

• It will actually start sshd, but it will be started in the background. This means that (a) the service sshd start command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.

If you want to run just ssh in a container, consider an example like this.

If you want to run sshd and other processes inside the container, you will need to investigate some sort of process supervisor.

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

You have the field in a string, so you'll need to convert it to datetime

order by CONVERT(datetime, EventDate ) desc

Use

var value = "" + 5 + 6;

to force it to strings.

If you deal with .xlsm file instead of .xls you can use the old method. I was trying to modify vbaProject.bin in .xlsm several times using DBP->DBx method by it didn't work, also changing value of DBP didn't. So I was very suprised that following worked :
1. Save .xlsm as .xls.
2. Use DBP->DBx method on .xls.
3. Unfortunately some erros may occur when using modified .xls file, I had to save .xls as .xlsx and add modules, then save as .xlsm.

x = x + 1 print(x) a = x + 5 print(a)

There is very useful module that can do this:

from file_read_backwards import FileReadBackwards

with FileReadBackwards("/tmp/file", encoding="utf-8") as frb:

# getting lines by lines starting from the last line up
for l in frb:
    print(l)

Here is a solution that does not require a SQL context, but maintains the metadata of a DataFrame.

a = sc.parallelize([['a', 'foo'], ['b', 'hem'], ['c', 'haw']]).toDF(['a_id', 'extra'])
b = sc.parallelize([['p1', 'a'], ['p2', 'b'], ['p3', 'c']]).toDF(["other", "b_id"])

c = a.join(b, a.a_id == b.b_id)

Then, c.show() yields:

+----+-----+-----+----+
|a_id|extra|other|b_id|
+----+-----+-----+----+
|   a|  foo|   p1|   a|
|   b|  hem|   p2|   b|
|   c|  haw|   p3|   c|
+----+-----+-----+----+

This would be a good candidate for MetaWhere if you're using Rails 3.0+, but it doesn't work on Rails 3.1. You might want to try out squeel instead. It's made by the same author. Here's how'd you'd perform an OR based chain:

Person.where{(name == "John") | (lastname == "Smith")}

You can mix and match AND/OR, among many other awesome things.

You'll have to use the "userInfo" variant and pass a NSDictionary object that contains the messageTotal integer:

NSDictionary* userInfo = @{@"total": @(messageTotal)};

NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
[nc postNotificationName:@"eRXReceived" object:self userInfo:userInfo];

On the receiving end you can access the userInfo dictionary as follows:

-(void) receiveTestNotification:(NSNotification*)notification
{
    if ([notification.name isEqualToString:@"TestNotification"])
    {
        NSDictionary* userInfo = notification.userInfo;
        NSNumber* total = (NSNumber*)userInfo[@"total"];
        NSLog (@"Successfully received test notification! %i", total.intValue);
    }
}

Your have dropped the Project in your workspace, and then trying to import it, that's the problem.

This has two solutions:

1. More your project folder outside your workspace in some other location and then try.

2. Go to File ---> new Project ---> Select the existing project radio button ---> browse to the project folder in your workspace ---> finish

Edited

Assume D:\MyDirectory\MyWorkSpace - Path of your WorkSpace

Drop your project which you want to import in Eclipse in MyDirectory folder Not in MyWorkSpace, and try.

Resolution: the app is not a webapp because it doesn't have an embedded container (e.g. Tomcat) on the classpath. Adding one fixed it. If you are using Maven, then add this in pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

For Gradle (build.gradle) it looks like

dependencies {
    compile 'org.springframework.boot:spring-boot-starter-web'
}

If you want all the ancestors rather than just the immediate ones, use inspect.getmro:

import inspect
print inspect.getmro(cls)

Usefully, this gives you all ancestor classes in the "method resolution order" -- i.e. the order in which the ancestors will be checked when resolving a method (or, actually, any other attribute -- methods and other attributes live in the same namespace in Python, after all;-).

    if(filename.contains("-")) //Check if older log contained -x
    {
         int lognumber = Int32.Parse(filename.substring(filename.lastIndexOf("-")+1, filename.Length-4); //Get old number, Can cause exception if the last digits aren't numbers
         lognumber++; //Increment lognumber by 1
         filename = filenamebase + "-" + lognumber + ".log"; //Override filename
    }
    else 
    {
         filename = filenamebase + "-1.log"; //Override filename
    }
    fs = File.Create(filename);
    fs.Close();

That's because the return type for [data bytes] is a void* c-style array, not a Uint8 (which is what Byte is a typedef for).

The error is because you are trying to set an allocated array when the return is a pointer type, what you are looking for is the getBytes:length: call which would look like:

[data getBytes:&byteData length:len];

Which fills the array you have allocated with data from the NSData object.

After brew install pyqt, you can brew test pyqt which will use the python you have got in your PATH in oder to do the test (show a Qt window).

For non-brewed Python, you'll have to set your PYTHONPATH as brew info pyqt will tell.

Sometimes it is necessary to open a new shell or tap in order to use the freshly brewed binaries.

I frequently check these issues by printing the sys.path from inside of python: python -c "import sys; print(sys.path)" The $(brew --prefix)/lib/pythonX.Y/site-packages have to be in the sys.path in order to be able to import stuff. As said, for brewed python, this is default but for any other python, you will have to set the PYTHONPATH.

You can do this:

cat("File not supplied.\nUsage: ./program F=filename\n")

Notice that cat has a return value of NULL.

I had a similar experience with Chai-Webdriver for Selenium. I added await to the assertion and it fixed the issue:

Example using Cucumberjs:

Then(/I see heading with the text of Tasks/, async function() {
    await chai.expect('h1').dom.to.contain.text('Tasks');
});

What you want to do is really important for unit testing. Basically you need to create a small local function in the view controller. Name the function anything, just include the performSegueWithIndentifier.

func localFunc() {
    println("we asked you to do it")
    performSegueWithIdentifier("doIt", sender: self)
}

Next change your utility class FBManager to include an initializer that takes an argument of a function and a variable to hold the ViewController's function that performs the segue.

public class UtilClass {

    var yourFunction : () -> ()

    init (someFunction: () -> ()) {
        self.yourFunction = someFunction
        println("initialized UtilClass")
    }

    public convenience init() {
        func dummyLog () -> () {
            println("no action passed")
        }
        self.init(dummyLog)
    }

    public func doThatThing() -> () {
        // the facebook login function
        println("now execute passed function")
        self.yourFunction()
        println("did that thing")
    }
}

(The convenience init allows you to use this in unit testing without executing the segue.)

Finally, where you have //todo: segue to the next view???, put something along the lines of:

self.yourFunction()

In your unit tests, you can simply invoke it as:

let f = UtilClass()
f.doThatThing()

where doThatThing is your fbsessionstatechange and UtilClass is FBManager.

For your actual code, just pass localFunc (no parenthesis) to the FBManager class.

Try sudo npm uninstall cordova -g to uninstall it globally and then just npm install cordova without the -g flag after cding to the local app directory

in your tsconfig you have to add: "esModuleInterop": true - it should help.

int wantedPosition = 25; // Whatever position you're looking for
int firstPosition = linearLayoutManager.findFirstVisibleItemPosition(); // This is the same as child #0
int wantedChild = wantedPosition - firstPosition;

if (wantedChild < 0 || wantedChild >= linearLayoutManager.getChildCount()) {
    Log.w(TAG, "Unable to get view for desired position, because it's not being displayed on screen.");
    return;
}

View wantedView = linearLayoutManager.getChildAt(wantedChild);
mlayoutOver =(LinearLayout)wantedView.findViewById(R.id.layout_over);
mlayoutPopup = (LinearLayout)wantedView.findViewById(R.id.layout_popup);

mlayoutOver.setVisibility(View.INVISIBLE);
mlayoutPopup.setVisibility(View.VISIBLE);

To elaborate on what @Raynos said, the function you have defined is an asynchronous callback. It doesn't execute right away, rather it executes when the file loading has completed. When you call readFile, control is returned immediately and the next line of code is executed. So when you call console.log, your callback has not yet been invoked, and this content has not yet been set. Welcome to asynchronous programming.

Example approaches

const fs = require('fs');
// First I want to read the file
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    const content = data;

    // Invoke the next step here however you like
    console.log(content);   // Put all of the code here (not the best solution)
    processFile(content);   // Or put the next step in a function and invoke it
});

function processFile(content) {
    console.log(content);
}

Or better yet, as Raynos example shows, wrap your call in a function and pass in your own callbacks. (Apparently this is better practice) I think getting into the habit of wrapping your async calls in function that takes a callback will save you a lot of trouble and messy code.

function doSomething (callback) {
    // any async callback invokes callback with response
}

doSomething (function doSomethingAfter(err, result) {
    // process the async result
});

For converting number as varchar to int, you could also use simple

(column + 0)

With PHP

echo urlencode("http://www.image.com/?username=unknown&password=unknown");

Result

http%3A%2F%2Fwww.image.com%2F%3Fusername%3Dunknown%26password%3Dunknown

With Javascript:

var myUrl = "http://www.image.com/?username=unknown&password=unknown";
var encodedURL= "http://www.foobar.com/foo?imageurl=" + encodeURIComponent(myUrl);

As previously answered here, String instances are immutable. StringBuffer and StringBuilder are mutable and suitable for such a purpose whether you need to be thread safe or not.

There is however a way to modify a String but I would never recommend it because it is unsafe, unreliable and it can can be considered as cheating : you can use reflection to modify the inner char array the String object contains. Reflection allows you to access fields and methods that are normally hidden in the current scope (private methods or fields from another class...).

public static void main(String[] args) {
    String text = "This is a test";
    try {
        //String.value is the array of char (char[])
        //that contains the text of the String
        Field valueField = String.class.getDeclaredField("value");
        //String.value is a private variable so it must be set as accessible 
        //to read and/or to modify its value
        valueField.setAccessible(true);
        //now we get the array the String instance is actually using
        char[] value = (char[])valueField.get(text);
        //The 13rd character is the "s" of the word "Test"
        value[12]='x';
        //We display the string which should be "This is a text"
        System.out.println(text);
    } catch (NoSuchFieldException | SecurityException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }
}

Or you can do it like as well:

<asp:DropDownList ID="ddl" runat="server"  AutoPostBack="true" onchange="javascript:CalcTotalAmt();" OnSelectedIndexChanged="ddl_SelectedIndexChanged"></asp:DropDownList>

In any case you can know it:

mysql> select @@datadir;

Inspired by Solomon's answer, but to stick with the question, which is related to histogram, a clean solution is:

sns.distplot(bar)
sns.distplot(foo)
plt.show()

Make sure to plot the taller one first, otherwise you would need to set plt.ylim(0,0.45) so that the taller histogram is not chopped off.

SELECT created
  FROM dba_objects
 WHERE object_name = <<your table name>>
   AND owner = <<owner of the table>>
   AND object_type = 'TABLE'

will tell you when a table was created (if you don't have access to DBA_OBJECTS, you could use ALL_OBJECTS instead assuming you have SELECT privileges on the table).

The general answer to getting timestamps from a row, though, is that you can only get that data if you have added columns to track that information (assuming, of course, that your application populates the columns as well). There are various special cases, however. If the DML happened relatively recently (most likely in the last couple hours), you should be able to get the timestamps from a flashback query. If the DML happened in the last few days (or however long you keep your archived logs), you could use LogMiner to extract the timestamps but that is going to be a very expensive operation particularly if you're getting timestamps for many rows. If you build the table with ROWDEPENDENCIES enabled (not the default), you can use

SELECT scn_to_timestamp( ora_rowscn ) last_modified_date,
       ora_rowscn last_modified_scn,
       <<other columns>>
  FROM <<your table>>

to get the last modification date and SCN (system change number) for the row. By default, though, without ROWDEPENDENCIES, the SCN is only at the block level. The SCN_TO_TIMESTAMP function also isn't going to be able to map SCN's to timestamps forever.

You can use the core with GDB in many ways, but passing parameters which is to be passed to the executable to GDB is not the way to use the core file. This could also be the reason you got that error. You can use the core file in the following ways:

gdb <executable> <core-file> or gdb <executable> -c <core-file> or

gdb <executable>
...
(gdb) core <core-file>

When using the core file you don't have to pass arguments. The crash scenario is shown in GDB (checked with GDB version 7.1 on Ubuntu).

For example:

$ ./crash -p param1 -o param2
Segmentation fault (core dumped)
$ gdb ./crash core
GNU gdb (GDB) 7.1-ubuntu
...
Core was generated by `./crash -p param1 -o param2'. <<<<< See this line shows crash scenario

If you want to pass parameters to the executable to be debugged in GDB, use --args.

You can use a FileOutputStream for this.

FileOutputStream fos = null;
try {
    fos = new FileOutputStream(new File("myFile")); 
    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    // Put data in your baos

    baos.writeTo(fos);
} catch(IOException ioe) {
    // Handle exception here
    ioe.printStackTrace();
} finally {
    fos.close();
}

If you want to do the background explicitly, you must be certain that you draw behind the current elements on the canvas.

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
// Add behind elements.
ctx.globalCompositeOperation = 'destination-over'
// Now draw!
ctx.fillStyle = "blue";
ctx.fillRect(0, 0, canvas.width, canvas.height);

you can go with sth like [^-]\d{4}$: you prevent the minus sign - to be before your 4 digits.
you can also use ^\d{4}$ with ^ to catch the beginning of the string. It depends on your scenario actually...

Figured it out for myself in the end. It is simple, I was just missing the ** operator to unpack the dictionary

So my example becomes:

d = dict(p1=1, p2=2)
def f2(p1,p2):
    print p1, p2
f2(**d)

enum MyEnum {VALUE_1,VALUE_2}

is (approximately) like saying

class MyEnum {

    public static final MyEnum VALUE_1 = new MyEnum("VALUE_1");
    public static final MyEnum VALUE_2 = new MyEnum("VALUE_2");

    private final name;

    private MyEnum(String name) {
        this.name = name;
    }

    public String name() { return this.name }
}

so I guess the all caps is strictly more correct, but still I use the class name convention since I hate all caps wherever

I'm not sure about what you're trying to do... maybe something like

SELECT gid, COUNT(*) AS num FROM gd GROUP BY gid HAVING num > 10 ORDER BY lastupdated DESC

We can use $set operator to update the nested array inside object filed update the value

   {
       "_id" : ObjectId("5bd3013ac714ea4959f80115"), 
       "geolocation.country" : "United States of America"
   }, 
   { $set: 
       {
           "geolocation.$.country" : "USA"
       } 
    }, 
   false,
   true
);

You should use

 SSLContext.getInstance("TLSv1.2"); 

for specific protocol version.

The second exception occured because default socketFactory used fallback SSLv3 protocol for failures.

You can use NoSSLFactory from main answer here for its suppression How to disable SSLv3 in android for HttpsUrlConnection?

Also you should init SSLContext with all your certificates(client and trusted ones if you need them)

But all of that is useless without using

ProviderInstaller.installIfNeeded(getContext())

No need to embed! Just simply send the user to google and add the var in the search like this: (Remember, code might not work on this, so try in a browser if it doesn't.) Hope it works!

<script>
function search() {
var Blah = document.getElementById("Blah").value;
location.replace("https://www.google.com/search?q=" + Blah + "");
}
</script>

    function search() {_x000D_
    var Blah = document.getElementById("Blah").value;_x000D_
    location.replace("https://www.google.com/search?q=" + Blah + "");_x000D_
    }

<textarea id="Blah"></textarea><button onclick="search()">Search</button>

Tray this short way

  var lower = (str+"").toLowerCase();

Put the textarea to a form, naming them, and just use the DOM objects easily, like this:

<body onload="form1.box.value = 'Welcome!'">
  <form name="form1">
    <textarea name="box"></textarea>
  </form>
</body>

Just use Control.Invoke Method or Control.BeginInvoke Method.

MKV container supports video and audio codecs Virtually anything and also supports subtitles and DVD menus. So you can just copy codecs from input video to output video with MKV container with subtitles. First you should convert SRT to ASS subtitle format

ffmpeg -i input.srt input.ass

and embed ASS subtitles to video

ffmpeg -i input.mp4 -i input.ass -c:v copy -c:a copy -c:s copy -map 0:0 -map 0:1 -map 1:0 -y out.mkv

Also worked with VMW file.

ffmpeg -i input.wmv -i input.ass -c:v copy -c:a copy -c:s copy -map 0:0 -map 0:1 -map 1:0 -y out.mkv

1. In my opinion, the most convenient way is to search for one occurrence first, and then invoke the following :substitute command:

:%s///gc

Since the pattern is empty, this :substitute command will look for the occurrences of the last-used search pattern, and will then replace them with the empty string, each time asking for user confirmation, realizing exactly the desired behavior.

2. If it is a common pattern in one’s editing habits, one can further define a couple of text-object selection mappings to operate specifically on the match of the last search pattern under the cursor. The following two mappings can be used in both Visual and Operator-pending modes to select the text of the preceding match of the last search pattern.

vnoremap <silent> i/ :<c-u>call SelectMatch()<cr>
onoremap <silent> i/ :call SelectMatch()<cr>
function! SelectMatch()
    if search(@/, 'bcW')
        norm! v
        call search(@/, 'ceW')
    else
        norm! gv
    endif
endfunction

Using these mappings one can delete the match under the cursor with di/, or apply any other operator or visually select it with vi/.

I don't believe this is possible - there is no ability to set the timezone on a Date object after it is created.

And in a way this makes sense - conceptually (if perhaps not in implementation); per http://en.wikipedia.org/wiki/Unix_timestamp (emphasis mine):

Unix time, or POSIX time, is a system for describing instants in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of Thursday, January 1, 1970.

Once you've constructed one it will represent a certain point in "real" time. The time zone is only relevant when you want to convert that abstract time point into a human-readable string.

Thus it makes sense you would only be able to change the actual time the Date represents in the constructor. Sadly it seems that there is no way to pass in an explicit timezone - and the constructor you are calling (arguably correctly) translates your "local" time variables into GMT when it stores them canonically - so there is no way to use the int, int, int constructor for GMT times.

On the plus side, it's trivial to just use the constructor that takes a String instead. You don't even have to convert the numeric month into a String (on Firefox at least), so I was hoping a naive implementation would work. However, after trying it out it works successfully in Firefox, Chrome, and Opera but fails in Konqueror ("Invalid Date") , Safari ("Invalid Date") and IE ("NaN"). I suppose you'd just have a lookup array to convert the month to a string, like so:

var months = [ '', 'January', 'February', ..., 'December'];

function createGMTDate(xiYear, xiMonth, xiDate) {
   return new Date(months[xiMonth] + ' ' + xiDate + ', ' + xiYear + ' 00:00:00 GMT');
}

My app was running on Nexus 5X API 26 x86 (virtual device on emulator) without any errors and then I included a third party AAR. Then it keeps giving this error. I cleaned, rebuilt, checked/unchecked instant run option, wiped the data in AVD, performed cold boot but problem insists. Then I tried the solution found here. he/she says that add splits & abi blocks for 'x86', 'armeabi-v7a' in to module build.gradle file and hallelujah it is clean and fresh again :)

Edit: On this post Driss Bounouar's solution seems to be same. But my emulator was x86 before adding the new AAR and HAXM emulator was already working.

So, like others said, definitely the best option is:

window['myfunction'](arguments)

And like Jason Bunting said, it won't work if the name of your function includes an object:

window['myobject.myfunction'](arguments); // won't work
window['myobject']['myfunction'](arguments); // will work

So here's my version of a function that will execute all functions by name (including an object or not):

my = {_x000D_
    code : {_x000D_
        is : {_x000D_
            nice : function(a, b){ alert(a + "," + b); }_x000D_
        }_x000D_
    }_x000D_
};_x000D_
_x000D_
guy = function(){ alert('awesome'); }_x000D_
_x000D_
function executeFunctionByName(str, args)_x000D_
{_x000D_
    var arr = str.split('.');_x000D_
    var fn = window[ arr[0] ];_x000D_
    _x000D_
    for (var i = 1; i < arr.length; i++)_x000D_
    { fn = fn[ arr[i] ]; }_x000D_
    fn.apply(window, args);_x000D_
}_x000D_
_x000D_
executeFunctionByName('my.code.is.nice', ['arg1', 'arg2']);_x000D_
executeFunctionByName('guy');

Solution for iOS 9:

NSString *language = [[NSLocale preferredLanguages] objectAtIndex:0];

language = "en-US"

NSDictionary *languageDic = [NSLocale componentsFromLocaleIdentifier:language];

languageDic will have the needed components

NSString *countryCode = [languageDic objectForKey:@"kCFLocaleCountryCodeKey"];

countryCode = "US"

NSString *languageCode = [languageDic objectForKey:@"kCFLocaleLanguageCodeKey"];

languageCode = "en"

This is an example of Python lists:

my_list = [0,1,2,3,4]
top_rock_list = ["Bohemian Rhapsody","Kashmir","Sweet Emotion", "Fortunate Son"]

This is an example of Python tuple:

my_tuple = (a,b,c,d,e)
celebrity_tuple = ("John", "Wayne", 90210, "Actor", "Male", "Dead")

Python lists and tuples are similar in that they both are ordered collections of values. Besides the shallow difference that lists are created using brackets "[ ... , ... ]" and tuples using parentheses "( ... , ... )", the core technical "hard coded in Python syntax" difference between them is that the elements of a particular tuple are immutable whereas lists are mutable (...so only tuples are hashable and can be used as dictionary/hash keys!). This gives rise to differences in how they can or can't be used (enforced a priori by syntax) and differences in how people choose to use them (encouraged as 'best practices,' a posteriori, this is what smart programers do). The main difference a posteriori in differentiating when tuples are used versus when lists are used lies in what meaning people give to the order of elements.

For tuples, 'order' signifies nothing more than just a specific 'structure' for holding information. What values are found in the first field can easily be switched into the second field as each provides values across two different dimensions or scales. They provide answers to different types of questions and are typically of the form: for a given object/subject, what are its attributes? The object/subject stays constant, the attributes differ.

For lists, 'order' signifies a sequence or a directionality. The second element MUST come after the first element because it's positioned in the 2nd place based on a particular and common scale or dimension. The elements are taken as a whole and mostly provide answers to a single question typically of the form, for a given attribute, how do these objects/subjects compare? The attribute stays constant, the object/subject differs.

There are countless examples of people in popular culture and programmers who don't conform to these differences and there are countless people who might use a salad fork for their main course. At the end of the day, it's fine and both can usually get the job done.

To summarize some of the finer details

Similarities:

1. Duplicates - Both tuples and lists allow for duplicates

2. Indexing, Selecting, & Slicing - Both tuples and lists index using integer values found within brackets. So, if you want the first 3 values of a given list or tuple, the syntax would be the same:

   >>> my_list[0:3]
   [0,1,2]
   >>> my_tuple[0:3]
   [a,b,c]
   

3. Comparing & Sorting - Two tuples or two lists are both compared by their first element, and if there is a tie, then by the second element, and so on. No further attention is paid to subsequent elements after earlier elements show a difference.

   >>> [0,2,0,0,0,0]>[0,0,0,0,0,500]
   True
   >>> (0,2,0,0,0,0)>(0,0,0,0,0,500)
   True
   

Differences: - A priori, by definition

1. Syntax - Lists use [], tuples use ()

2. Mutability - Elements in a given list are mutable, elements in a given tuple are NOT mutable.

   # Lists are mutable:
   >>> top_rock_list
   ['Bohemian Rhapsody', 'Kashmir', 'Sweet Emotion', 'Fortunate Son']
   >>> top_rock_list[1]
   'Kashmir'
   >>> top_rock_list[1] = "Stairway to Heaven"
   >>> top_rock_list
   ['Bohemian Rhapsody', 'Stairway to Heaven', 'Sweet Emotion', 'Fortunate Son']
   
   # Tuples are NOT mutable:       
   >>> celebrity_tuple
   ('John', 'Wayne', 90210, 'Actor', 'Male', 'Dead')
   >>> celebrity_tuple[5]
   'Dead'
   >>> celebrity_tuple[5]="Alive"
   Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   TypeError: 'tuple' object does not support item assignment
   

3. Hashtables (Dictionaries) - As hashtables (dictionaries) require that its keys are hashable and therefore immutable, only tuples can act as dictionary keys, not lists.

   #Lists CAN'T act as keys for hashtables(dictionaries)
   >>> my_dict = {[a,b,c]:"some value"}
   Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   TypeError: unhashable type: 'list'
   
   #Tuples CAN act as keys for hashtables(dictionaries)
   >>> my_dict = {("John","Wayne"): 90210}
   >>> my_dict
   {('John', 'Wayne'): 90210}
   

Differences - A posteriori, in usage

1. Homo vs. Heterogeneity of Elements - Generally list objects are homogenous and tuple objects are heterogeneous. That is, lists are used for objects/subjects of the same type (like all presidential candidates, or all songs, or all runners) whereas although it's not forced by), whereas tuples are more for heterogenous objects.

2. Looping vs. Structures - Although both allow for looping (for x in my_list...), it only really makes sense to do it for a list. Tuples are more appropriate for structuring and presenting information (%s %s residing in %s is an %s and presently %s % ("John","Wayne",90210, "Actor","Dead"))

look at it is informative [Qualified identifiers

A qualified id-expression is an unqualified id-expression prepended by a scope resolution operator ::, and optionally, a sequence of enumeration, (since C++11)class or namespace names or decltype expressions (since C++11) separated by scope resolution operators. For example, the expression std::string::npos is an expression that names the static member npos in the class string in namespace std. The expression ::tolower names the function tolower in the global namespace. The expression ::std::cout names the global variable cout in namespace std, which is a top-level namespace. The expression boost::signals2::connection names the type connection declared in namespace signals2, which is declared in namespace boost.

The keyword template may appear in qualified identifiers as necessary to disambiguate dependent template names]1

</div>

The current state of a socket is determined by 'keep-alive' activity. In your case, this is possible that when you are issuing the send call, the keep-alive activity tells that the socket is active and so the send call will write the required data (40 bytes) in to the buffer and returns without giving any error.

When you are sending a bigger chunk, the send call goes in to blocking state.

The send man page also confirms this:

When the message does not fit into the send buffer of the socket, send() normally blocks, unless the socket has been placed in non-blocking I/O mode. In non-blocking mode it would return EAGAIN in this case

So, while blocking for the free available buffer, if the caller is notified (by keep-alive mechanism) that the other end is no more present, the send call will fail.

Predicting the exact scenario is difficult with the mentioned info, but I believe, this should be the reason for you problem.

.service-small option {
    font-size: 14px;
    padding: 5px;
    background: #5c5c5c;
}

I think it because you used .styled-select in start of the class code.

In production, you'll just have the HTML generated from your template pointing to wherever the host has media files stored. So your template will just have for example

<img src="../media/foo.png">

And then you'll just make sure that directory is there with the relevant file(s).

during development is a different issue. The django docs explain it succinctly and clearly enough that it's more effective to link there and type it up here, but basically you'll define a view for site media with a hardcoded path to location on disk.

Right here.

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

Update

the library already have Java/Kotlin support, see github.

Original

To simplify I did a class to be used simply, I added it on Encryption library to use it you just do as follow:

Add the gradle library:

compile 'se.simbio.encryption:library:2.0.0'

and use it:

Encryption encryption = Encryption.getDefault("Key", "Salt", new byte[16]);
String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);

if you not want add the Encryption library you can just copy the following class to your project. If you are in an android project you need to import android Base64 in this class, if you are in a pure java project you need to add this class manually you can get it here

You can use Enum.Parse like, if it is string

Use java-google-translate-text-to-speech instead of Google Translate API v2 Java.

About java-google-translate-text-to-speech

Api unofficial with the main features of Google Translate in Java.

Easy to use!

It also provide text to speech api. If you want to translate the text "Hello!" in Romanian just write:

Translator translate = Translator.getInstance();
String text = translate.translate("Hello!", Language.ENGLISH, Language.ROMANIAN);
System.out.println(text); // "Buna ziua!" 

It's free!

As @r0ast3d correctly said:

Important: Google Translate API v2 is now available as a paid service. The courtesy limit for existing Translate API v2 projects created prior to August 24, 2011 will be reduced to zero on December 1, 2011. In addition, the number of requests your application can make per day will be limited.

This is correct: just see the official page:

Google Translate API is available as a paid service. See the Pricing and FAQ pages for details.

BUT, java-google-translate-text-to-speech is FREE!

Example!

I've created a sample application that demonstrates that this works. Try it here: https://github.com/IonicaBizau/text-to-speech

Excel ColumnWidth from dataGridView:

           foreach (DataGridViewColumn co in dataGridView1.Columns)
           { worksheet.Columns[co.Index + 1].ColumnWidth = co.Width/8; }

If you are an analyst and not a full stack guy, this might be more intuitive:

[(str('00000') + str(i))[-5:] for i in arange(100)]

breaking that down, you:

• start by creating a list that repeats 0's or X's, in this case, 100 long, i.e., arange(100)

• add the numbers you want to the string, in this case, numbers 0-99, i.e., 'i'

• keep only the right hand 5 digits, i.e., '[-5:]' for subsetting

• output is numbered list, all with 5 digits

In LinearLayout, use: android:layout_gravity="center".

In RelativeLayout, use: android:layout_centerInParent="true".

This was resolved. It turns out our IT Staff was correct. Both TLS 1.1 and TLS 1.2 were installed on the server. However, the issue was that our sites are running as ASP.NET 4.0 and you have to have ASP.NET 4.5 to run TLS 1.1 or TLS 1.2. So, to resolve the issue, our IT Staff had to re-enable TLS 1.0 to allow a connection with PayTrace.

So in short, the error message, "the client and server cannot communicate, because they do not possess a common algorithm", was caused because there was no SSL Protocol available on the server to communicate with PayTrace's servers.

UPDATE: Please do not enable TLS 1.0 on your servers, this was a temporary fix and is not longer applicable since there are now better work-arounds that ensure strong security practices. Please see accepted answer for a solution. FYI, I'm going to keep this answer on the site as it provides information on what the problem was, please do not down-vote.

An alternative, and perhaps a not so good procedural coding one, is to send the "function name" to a script that then executes the function. For instance, with a login form, there is typically the login, forgotusername, forgotpassword, signin activities that are presented on the form as buttons or anchors. All of these can be directed to/as, say,

weblogin.php?function=login
weblogin.php?function=forgotusername
weblogin.php?function=forgotpassword
weblogin.php?function=signin

And then a switch statement on the receiving page does any prep work and then dispatches or runs the (next) specified function.

If you already know the process then this will be useful:

PID=`ps -eaf | grep <process> | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
echo "killing $PID"
kill -9 $PID
fi

I found them useful in a situation when I wanted to declare a handler for some control's event, using another control. To do it normally you would have to store controls' references in fields of the class so that you could use them in a different method than they were created.

private ComboBox combo;
private Label label;

public CreateControls()
{
    combo = new ComboBox();
    label = new Label();
    //some initializing code
    combo.SelectedIndexChanged += new EventHandler(combo_SelectedIndexChanged);
}

void combo_SelectedIndexChanged(object sender, EventArgs e)
{
    label.Text = combo.SelectedValue;
}

thanks to lambda expressions you can use it like this:

public CreateControls()
{
    ComboBox combo = new ComboBox();
    Label label = new Label();
    //some initializing code
    combo.SelectedIndexChanged += (s, e) => {label.Text = combo.SelectedValue;};
}

Much easier.

Try this:

CSS

.style1{
    background-color:red;
    color:white;
    font-size:44px;
}

HTML

<div id="foo">hello world!</div>
<img src="zoom.png" onclick="myFunction()" />

Javascript

function myFunction()
{
    document.getElementById('foo').setAttribute("class", "style1");
}

If you have several specific properties that you want to transition in the same way (because you also have some properties you specifically don't want to transition, say opacity), another option is to do something like this (prefixes omitted for brevity):

.myclass {
    transition: all 200ms ease;
    transition-property: box-shadow, height, width, background, font-size;
}

The second declaration overrides the all in the shorthand declaration above it and makes for (occasionally) more concise code.

/* prefixes omitted for brevity */_x000D_
.box {_x000D_
    height: 100px;_x000D_
    width: 100px;_x000D_
    background: red;_x000D_
    box-shadow: red 0 0 5px 1px;_x000D_
    transition: all 500ms ease;_x000D_
    /*note: not transitioning width */_x000D_
    transition-property: height, background, box-shadow;_x000D_
}_x000D_
_x000D_
.box:hover {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  box-shadow: blue 0 0 10px 3px;_x000D_
  background: blue;_x000D_
}

<p>Hover box for demo</p>_x000D_
<div class="box"></div>

Demo

In the event someone needs a generic version of mattsven's answer (as I did), here it is:

$('select').each(function() {
    $(this).data('lastSelected', $(this).find('option:selected'));
});

$('select').change(function() {
    if(my_condition) {
        $(this).data('lastSelected').attr('selected', true);
    }
});

$('select').click(function() {
    $(this).data('lastSelected', $(this).find('option:selected'));
});

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

I modified the accepted answer and now it can get the command including primary key and foreign key in a certain schema.

declare @table varchar(100)
declare @schema varchar(100)
set @table = 'Persons' -- set table name here
set @schema = 'OT' -- set SCHEMA name here
declare @sql table(s varchar(1000), id int identity)

-- create statement
insert into  @sql(s) values ('create table ' + @table + ' (')

-- column list
insert into @sql(s)

I also had this issue using Lumen, but fixed by setting DB_STRICT_MODE=false in .env file.

fname = "feed.txt"
feed = open(fname, 'r')

num_lines = len(feed.splitlines())
num_words = 0
num_chars = 0

for line in lines:
    num_words += len(line.split())

I deleted my eclipse.ini after non of the above worked for me.

I fully expected the next run (when it looked likely to work) to recreate it so I could compare but it did not.

So I can't tell what fixed it specifically.

an oddity I did have however was jdk 1.7 but when I ran

C:\Users\jonathan.hardcastle>java -version Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion' has value '1.7', but '1.6' is required. Error: could not find java.dll Error: could not find Java SE Runtime Environment.

i got the above.. so I (re?)installed jre 1.7 specifically and that went away.

This was not linked to my eclipse success directly.

If your data.frame is a data.table, you can use special symbol .I:

data[, ID := .I]

Here cascade, in the context of remove, means that the children are removed if you remove the parent. Not the association. If you are using Hibernate as your JPA provider, you can do it using hibernate specific cascade.

Seems like the accepted answer does not work anymore. I found the correct method from another post: https://stackoverflow.com/a/46811403/6368026

Now you should use:

http://www.youtube.com/embed/videoseries?list=USERID And the USERID is your youtube user id with 'UU' appended.

For example, if your user id is TlQ5niAIDsLdEHpQKQsupg then you should put UUTlQ5niAIDsLdEHpQKQsupg. If you only have the channel id (which you can find in your channel URL) then just replace the first two characters (UC) with UU.

So in the end you would have an URL like this:

http://www.youtube.com/embed/videoseries?list=UUTlQ5niAIDsLdEHpQKQsupg

^[0-9]{1,2}[:.,-]?po$

Add any other allowable non-alphanumeric characters to the middle brackets to allow them to be parsed as well.

Something like:

class Tree {

 struct node {
   int data;
   node *llink;
   node *rlink;
 };
 .....
 .....
 .....
};

You can use this snippet :-D

using System;
using System.Reflection;

public static class EnumUtils
{
    public static T GetDefaultValue<T>()
        where T : struct, Enum
    {
        return (T)GetDefaultValue(typeof(T));
    }

    public static object GetDefaultValue(Type enumType)
    {
        var attribute = enumType.GetCustomAttribute<DefaultValueAttribute>(inherit: false);
        if (attribute != null)
            return attribute.Value;

        var innerType = enumType.GetEnumUnderlyingType();
        var zero = Activator.CreateInstance(innerType);
        if (enumType.IsEnumDefined(zero))
            return zero;

        var values = enumType.GetEnumValues();
        return values.GetValue(0);
    }
}

Example:

using System;

public enum Enum1
{
    Foo,
    Bar,
    Baz,
    Quux
}
public enum Enum2
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 0
}
public enum Enum3
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}
[DefaultValue(Enum4.Bar)]
public enum Enum4
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}

public static class Program 
{
    public static void Main() 
    {
        var defaultValue1 = EnumUtils.GetDefaultValue<Enum1>();
        Console.WriteLine(defaultValue1); // Foo

        var defaultValue2 = EnumUtils.GetDefaultValue<Enum2>();
        Console.WriteLine(defaultValue2); // Quux

        var defaultValue3 = EnumUtils.GetDefaultValue<Enum3>();
        Console.WriteLine(defaultValue3); // Foo

        var defaultValue4 = EnumUtils.GetDefaultValue<Enum4>();
        Console.WriteLine(defaultValue4); // Bar
    }
}

try:

header('Location: ' . $_SERVER['HTTP_REFERER']);

Note that this may not work with secure pages (HTTPS) and it's a pretty bad idea overall as the header can be hijacked, sending the user to some other destination. The header may not even be sent by the browser.

Ideally, you will want to either:

• Append the return address to the request as a query variable (eg. ?back=/list)
• Define a return page in your code (ie. all successful form submissions redirect to the listing page)
• Provide the user the option of where they want to go next (eg. Save and continue editing or just Save)
