I built quicktype exactly for this purpose. Just paste your sample JSON and quicktype generates this type hierarchy for your API data:

struct Forecast {
    let hourly: Hourly
    let daily: Daily
    let currently: Currently
    let flags: Flags
    let longitude: Double
    let latitude: Double
    let offset: Int
    let timezone: String
}

struct Hourly {
    let icon: String
    let data: [Currently]
    let summary: String
}

struct Daily {
    let icon: String
    let data: [Datum]
    let summary: String
}

struct Datum {
    let precipIntensityMax: Double
    let apparentTemperatureMinTime: Int
    let apparentTemperatureLowTime: Int
    let apparentTemperatureHighTime: Int
    let apparentTemperatureHigh: Double
    let apparentTemperatureLow: Double
    let apparentTemperatureMaxTime: Int
    let apparentTemperatureMax: Double
    let apparentTemperatureMin: Double
    let icon: String
    let dewPoint: Double
    let cloudCover: Double
    let humidity: Double
    let ozone: Double
    let moonPhase: Double
    let precipIntensity: Double
    let temperatureHigh: Double
    let pressure: Double
    let precipProbability: Double
    let precipIntensityMaxTime: Int
    let precipType: String?
    let sunriseTime: Int
    let summary: String
    let sunsetTime: Int
    let temperatureMax: Double
    let time: Int
    let temperatureLow: Double
    let temperatureHighTime: Int
    let temperatureLowTime: Int
    let temperatureMin: Double
    let temperatureMaxTime: Int
    let temperatureMinTime: Int
    let uvIndexTime: Int
    let windGust: Double
    let uvIndex: Int
    let windBearing: Int
    let windGustTime: Int
    let windSpeed: Double
}

struct Currently {
    let precipProbability: Double
    let humidity: Double
    let cloudCover: Double
    let apparentTemperature: Double
    let dewPoint: Double
    let ozone: Double
    let icon: String
    let precipIntensity: Double
    let temperature: Double
    let pressure: Double
    let precipType: String?
    let summary: String
    let uvIndex: Int
    let windGust: Double
    let time: Int
    let windBearing: Int
    let windSpeed: Double
}

struct Flags {
    let sources: [String]
    let isdStations: [String]
    let units: String
}

It also generates dependency-free marshaling code to coax the return value of JSONSerialization.jsonObject into a Forecast, including a convenience constructor that takes a JSON string so you can quickly parse a strongly typed Forecast value and access its fields:

let forecast = Forecast.from(json: jsonString)!
print(forecast.daily.data[0].windGustTime)

You can install quicktype from npm with npm i -g quicktype or use the web UI to get the complete generated code to paste into your playground.

This is really simple , just add this in web.config

<system.webServer>
  <httpProtocol>
    <customHeaders>
      <add name="Access-Control-Allow-Origin" value="http://localhost" />
      <add name="Access-Control-Allow-Headers" value="X-AspNet-Version,X-Powered-By,Date,Server,Accept,Accept-Encoding,Accept-Language,Cache-Control,Connection,Content-Length,Content-Type,Host,Origin,Pragma,Referer,User-Agent" />
      <add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, OPTIONS" />
      <add name="Access-Control-Max-Age" value="1000" />
    </customHeaders>
  </httpProtocol>
</system.webServer>

In Origin put all domains that have access to your web server, in headers put all possible headers that any ajax http request can use, in methods put all methods that you allow on your server

First case:

A normal product lookup would look like this

http://our.api.com/product/1

So Im thinking that best practice would be for you to do this

http://our.api.com/Product/101404,7267261

Second Case

Search with querystring parameters - fine like this. I would be tempted to combine terms with AND and OR instead of using [].

PS This can be subjective, so do what you feel comfortable with.

The reason for putting the data in the url is so the link can pasted on a site/ shared between users. If this isnt an issue, by all means use a JSON/ POST instead.

EDIT: On reflection I think this approach suits an entity with a compound key, but not a query for multiple entities.

I think the answer depends on which features of stored procedures you need to use.

Stored procedures returning a result set can be run using Query; stored procedures which don't return a result set can be run using Execute - in both cases (using EXEC <procname>) as the SQL command (plus input parameters as necessary). See the documentation for more details.

As of revision 2d128ccdc9a2 there doesn't appear to be native support for OUTPUT parameters; you could add this, or alternatively construct a more complex Query command which declared TSQL variables, executed the SP collecting OUTPUT parameters into the local variables and finallyreturned them in a result set:

DECLARE @output int

EXEC <some stored proc> @i = @output OUTPUT

SELECT @output AS output1

Use a MemoryStream instead of a FileStream, like this:

MemoryStream ms = new MemoryStream();
bmp.Save (ms, ImageFormat.Jpeg);
byte[] bmpBytes = ms.ToArray();

In my case, the original repository was a bare one.

So, I had to type (in windows):

mkdir   dest
cd dest
git init
git remote add origin a\valid\yet\bare\repository
git pull origin master

To check if a repository is a bare one:

git rev-parse --is-bare-repository 

Here is what i tried to do to add parameter in the url which contain the specific character in the url.

jQuery('a[href*="google.com"]').attr('href', function(i,href) {
        //jquery date addition
        var requiredDate = new Date();
        var numberOfDaysToAdd = 60;
        requiredDate.setDate(requiredDate.getDate() + numberOfDaysToAdd); 
        //var convertedDate  = requiredDate.format('d-M-Y');
        //var newDate = datepicker.formatDate('yy/mm/dd', requiredDate );
        //console.log(requiredDate);

        var month   = requiredDate.getMonth()+1;
        var day     = requiredDate.getDate();

        var output = requiredDate.getFullYear() + '/' + ((''+month).length<2 ? '0' : '') + month + '/' + ((''+day).length<2 ? '0' : '') + day;
        //

Working Example Click

Try this:

Date date = new Date(logEvent.timeSTamp);
DateFormat formatter = new SimpleDateFormat("HH:mm:ss.SSS");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
String dateFormatted = formatter.format(date);

See SimpleDateFormat for a description of other format strings that the class accepts.

See runnable example using input of 1200 ms.

I was having a lot of problems to get this working, every single solution I found didn't seem to work.

I realized that I had to set the div display to flex, so basically this is my CSS:

div{
display: flex;
}

div img{ 
max-height: 100%;
max-width: 100%;
}

In Android Studio 3.4.1, you can use the search feature of Android Studio to find "Device File Explorer" and then go to the /data/data/package_name/database directory of your emulator.

A big difference is if you are displaying arrays. Especially ones with NIL. For example:

print [nil, 1, 2]

gives

[nil, 1, 2]

but

puts [nil, 1, 2]

gives

1
2

Note, no appearing nil item (just a blank line) and each item on a different line.

Here is a working fiddle with indeterminate number of cells: http://jsfiddle.net/r9yrM/1/

You can fix a width to each parent div (the table), otherwise it'll be 100% as usual.

The trick is to use table-layout: fixed; and some width on each cell to trigger it, here 2%. That will trigger the other table algorightm, the one where browsers try very hard to respect the dimensions indicated.
Please test with Chrome (and IE8- if needed). It's OK with a recent Safari but I can't remember the compatibility of this trick with them.

CSS (relevant instructions):

div {
    display: table;
    width: 250px;
    table-layout: fixed;
}

div > div {
    display: table-cell;
    width: 2%; /* or 100% according to OP comment. See edit about Safari 6 below */
}

EDIT (2013): Beware of Safari 6 on OS X, it has table-layout: fixed; wrong (or maybe just different, very different from other browsers. I didn't proof-read CSS2.1 REC table layout ;) ). Be prepared to different results.

There are a couple of things to be aware of:

• The Ant matchers match against the request path and not the path of the resource on the filesystem.
• Resources placed in src/main/resources/public will be served from the root of your application. For example src/main/resources/public/hello.jpg would be served from http://localhost:8080/hello.jpg

This is why your current matcher configuration hasn't permitted access to the static resources. For /resources/** to work, you would have to place the resources in src/main/resources/public/resources and access them at http://localhost:8080/resources/your-resource.

As you're using Spring Boot, you may want to consider using its defaults rather than adding extra configuration. Spring Boot will, by default, permit access to /css/**, /js/**, /images/**, and /**/favicon.ico. You could, for example, have a file named src/main/resources/public/images/hello.jpg and, without adding any extra configuration, it would be accessible at http://localhost:8080/images/hello.jpg without having to log in. You can see this in action in the web method security smoke test where access is permitted to the Bootstrap CSS file without any special configuration.

changing java proxy settings to direct connection did not fix my issue.

What worked for me:

1. Run "Configure Java" as administrator.
2. Go to Advanced
3. Scroll to bottom
4. Under: "Advanced Security Settings" uncheck "Use SSL 2.0 compatible ClientHello format"
5. Save

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

defaultConfig {
    multiDexEnabled true
}

In Kotlin,you can use using alpha like this,

   //Click on On.//
    view.rel_on.setOnClickListener{
        view.rel_off.alpha= 0.2F
        view.rel_on.alpha= 1F

    }

    //Click on Off.//
    view.rel_off.setOnClickListener {
        view.rel_on.alpha= 0.2F
        view.rel_off.alpha= 1F
    }

Result is like in this screen shots.

Hope this will help you.Thanks

Something like this might make it a bit easier, you could obviously use a script to generate this, or even excel

);

If your project is CLI (Common Language Runtime Support), then:

You can use the array class, not that one you get when you write:

#include <array>
using namespace std;

In other words, not the unmanaged array class you get when using the std namespace and when including the array header, not the unmanaged array class defined in the std namespace and in the array header, but the managed class array of the CLI.

with this class, you can create an array of any rank you want.

The following code below creates new two dimensional array of 2 rows and 3 columns and of type int, and I name it "arr":

array<int, 2>^ arr = gcnew array<int, 2>(2, 3);

Now you can access elements in the array, by name it and write only one squared parentheses [], and inside them, add the row and column, and separate them with the comma ,.

The following code below access an element in 2nd row and 1st column of the array I already created in previous code above:

arr[0, 1]

writing only this line is to read the value in that cell, i.e. get the value in this cell, but if you add the equal = sign, you are about to write the value in that cell, i.e. set the value in this cell. You also can use the +=, -=, *= and /= operators of course, for numbers only (int, float, double, __int16, __int32, __int64 and etc), but sure you know it already.

If your project is not CLI, then you can use the unmanaged array class of the std namespace, if you #include <array>, of course, but the problem is that this array class is different than the CLI array. Create array of this type is same like the CLI, except that you will have to remove the ^ sign and the gcnew keyword. But unfortunately the second int parameter in the <> parentheses specifies the length (i.e. size) of the array, not its rank!

There is no way to specify rank in this kind of array, rank is CLI array's feature only..

std array behaves like normal array in c++, that you define with pointer, for example int* and then: new int[size], or without pointer: int arr[size], but unlike the normal array of the c++, std array provides functions that you can use with the elements of the array, like fill, begin, end, size, and etc, but normal array provides nothing.

But still std array are one dimensional array, like the normal c++ arrays. But thanks to the solutions that the other guys suggest about how you can make the normal c++ one dimensional array to two dimensional array, we can adapt the same ideas to std array, e.g. according to Mehrdad Afshari's idea, we can write the following code:

array<array<int, 3>, 2> array2d = array<array<int, 3>, 2>();

This line of code creates a "jugged array", which is an one dimensional array that each of its cells is or points to another one dimensional array.

If all one dimensional arrays in one dimensional array are equal in their length/size, then you can treat the array2d variable as a real two dimensional array, plus you can use the special methods to treat rows or columns, depends on how you view it in mind, in the 2D array, that std array supports.

You also can use Kevin Loney's solution:

int *ary = new int[sizeX*sizeY];

// ary[i][j] is then rewritten as
ary[i*sizeY+j]

but if you use std array, the code must look different:

array<int, sizeX*sizeY> ary = array<int, sizeX*sizeY>();
ary.at(i*sizeY+j);

And still have the unique functions of the std array.

Note that you still can access the elements of the std array using the [] parentheses, and you don't have to call the at function. You also can define and assign new int variable that will calculate and keep the total number of elements in the std array, and use its value, instead of repeating sizeX*sizeY

You can define your own two dimensional array generic class, and define the constructor of the two dimensional array class to receive two integers to specify the number of rows and columns in the new two dimensional array, and define get function that receive two parameters of integer that access an element in the two dimensional array and returns its value, and set function that receives three parameters, that the two first are integers that specify the row and column in the two dimensional array, and the third parameter is the new value of the element. Its type depends on the type you chose in the generic class.

You will be able to implement all this by using either the normal c++ array (pointers or without) or the std array and use one of the ideas that other people suggested, and make it easy to use like the cli array, or like the two dimensional array that you can define, assign and use in C#.

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

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

I had the same issue but the below steps helped me to get out of it.

1. Installing the 'webpack-dev-server' locally (In the project directory as it was not picking from the global installation)

   npm install --save webpack-dev-server

Can verify whether 'webpack-dev-server' folder exists inside node_modules.

2. Running using npx for running directly

npx webpack-dev-server --mode development --config ./webpack.dev.js

npm run start also works fine where your entry in package.json scripts should be like the above like without npx.

are you writing java code for android? in that case you should write maybe

if (90 >= angle && angle <= 180) {

updating the code to a nicer style (like some suggested) you would get:

if (angle <= 90 && angle <= 180) {

now you see that the second check is unnecessary or maybe you mixed up < and > signs in the first check and wanted actually to have

if (angle >= 90 && angle <= 180) {

Mine works on NSMutableArray with componentsJoinedByString

var array = ["1", "2", "3"]
let stringRepresentation = array.componentsJoinedByString("-") // "1-2-3"

If you are using Rails 5 and above, the following solution will work.

#delete based on id
user_id = 50
User.find(id: user_id).delete_all

#delete based on condition
threshold_age = 20
User.where(age: threshold_age).delete_all

The home-grown core Java solution that I use to decorate existing factories:

public class ThreadFactoryNameDecorator implements ThreadFactory {
    private final ThreadFactory defaultThreadFactory;
    private final String suffix;

    public ThreadFactoryNameDecorator(String suffix) {
        this(Executors.defaultThreadFactory(), suffix);
    }

    public ThreadFactoryNameDecorator(ThreadFactory threadFactory, String suffix) {
        this.defaultThreadFactory = threadFactory;
        this.suffix = suffix;
    }

    @Override
    public Thread newThread(Runnable task) {
        Thread thread = defaultThreadFactory.newThread(task);
        thread.setName(thread.getName() + "-" + suffix);
        return thread;
    }
}

In action:

Executors.newSingleThreadExecutor(new ThreadFactoryNameDecorator("foo"));

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

You may use a implementation of Callable such that

public class MyAsyncCallable<V> implements Callable<V> {

    CallbackInterface ci;

    public MyAsyncCallable(CallbackInterface ci) {
        this.ci = ci;
    }

    public V call() throws Exception {

        System.out.println("Call of MyCallable invoked");
        System.out.println("Result = " + this.ci.doSomething(10, 20));
        return (V) "Good job";
    }
}

where CallbackInterface is something very basic like

public interface CallbackInterface {
    public int doSomething(int a, int b);
}

and now the main class will look like this

ExecutorService ex = Executors.newFixedThreadPool(2);

MyAsyncCallable<String> mac = new MyAsyncCallable<String>((a, b) -> a + b);
ex.submit(mac);

Firstly, I'd recommend breaking the module up into the useful things you need. But you can always create a class extending that for your invocation:

module UsefulThings
  def a
    puts "aaay"
  end
  def b
    puts "beee"
  end
end

def test
  ob = Class.new.send(:include, UsefulThings).new
  ob.a
end

test

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

Many things changed since 2009, but I can only find answers saying you need to use NamedParametersJDBCTemplate.

For me it works if I just do a

db.query(sql, new MyRowMapper(), StringUtils.join(listeParamsForInClause, ","));

using SimpleJDBCTemplate or JDBCTemplate

Since you need to match content without including it in the result (must match name=" but it's not part of the desired result) some form of zero-width matching or group capturing is required. This can be done easily with the following tools:

Perl

With Perl you could use the n option to loop line by line and print the content of a capturing group if it matches:

perl -ne 'print "$1\n" if /name="(.*?)"/' filename

GNU grep

If you have an improved version of grep, such as GNU grep, you may have the -P option available. This option will enable Perl-like regex, allowing you to use \K which is a shorthand lookbehind. It will reset the match position, so anything before it is zero-width.

grep -Po 'name="\K.*?(?=")' filename

The o option makes grep print only the matched text, instead of the whole line.

Vim - Text Editor

Another way is to use a text editor directly. With Vim, one of the various ways of accomplishing this would be to delete lines without name= and then extract the content from the resulting lines:

:v/.*name="\v([^"]+).*/d|%s//\1

Standard grep

If you don't have access to these tools, for some reason, something similar could be achieved with standard grep. However, without the look around it will require some cleanup later:

grep -o 'name="[^"]*"' filename

A note about saving results

In all of the commands above the results will be sent to stdout. It's important to remember that you can always save them by piping it to a file by appending:

> result

to the end of the command.

Add ArrayList1, ArrayList2 and produce a Single arraylist ArrayList3. Now convert it into

Set Unique_set = new HashSet(Arraylist3);

in the unique set you will get the unique elements.
Note

ArrayList allows to duplicate values. Set doesn't allow the values to duplicate. Hope your problem solves.

1)declare the structs before the main function. it worked for me. 2) And also fix the spelling mistake of that variable name if any e

compareTo() not only applies to Strings but also any other object because compareTo<T> takes a generic argument T. String is one of the classes that has implemented the compareTo() method by implementing the Comparable interface.(compareTo() is a method fo the comparable Interface). So any class is free to implement the Comparable interface.

But compareTo() gives the ordering of objects, used typically in sorting objects in ascending or descending order while equals() will only talk about the equality and say whether they are equal or not.

       //....your actions for the keys .....
    }
 });

To set the focus on start:

$(function() {
   $('#mydiv').focus();
});

To remove - if you don't like it - the div focus border, set outline: none in the CSS.

See the table of keycodes for more keyCode possibilities.

All of the code assuming you use jQuery.

I also have used the table approach. However, there is overhead. Why store a second list of pointers? A function in C without the () is a const pointer. So you can do:

struct state;
typedef void (*state_func_t)( struct state* );

typedef struct state
{
  state_func_t function;

  // other stateful data

} state_t;

void do_state_initial( state_t* );
void do_state_foo( state_t* );
void do_state_bar( state_t* );

void run_state( state_t* i ) {
    i->function(i);
};

int main( void ) {
    state_t state = { do_state_initial };

    while ( 1 ) {
        run_state( state );

        // do other program logic, run other state machines, etc
    }
}

Of course depending on your fear factor (i.e. safety vs speed) you may want to check for valid pointers. For state machines larger than three or so states, the approach above should be less instructions than an equivalent switch or table approach. You could even macro-ize as:

#define RUN_STATE(state_ptr_) ((state_ptr_)->function(state_ptr_))

Also, I feel from the OP's example, that there is a simplification that should be done when thinking about / designing a state machine. I don't thing the transitioning state should be used for logic. Each state function should be able to perform its given role without explicit knowledge of past state(s). Basically you design for how to transition from the state you are in to another state.

Finally, don't start the design of a state machine based on "functional" boundaries, use sub-functions for that. Instead divide the states based on when you will have to wait for something to happen before you can continue. This will help minimize the number of times you have to run the state machine before you get a result. This can be important when writing I/O functions, or interrupt handlers.

Also, a few pros and cons of the classic switch statement:

Pros:

• it is in the language, so it is documented and clear
• states are defined where they are called
• can execute multiple states in one function call
• code common to all states can be executed before and after the switch statement

Cons:

• can execute multiple states in one function call
• code common to all states can be executed before and after the switch statement
• switch implementation can be slow

Note the two attributes that are both pro and con. I think the switch allows the opportunity for too much sharing between states, and the interdependency between states can become unmanageable. However for a small number of states, it may be the most readable and maintainable.

May I recommend you corn-httpclient. It's simple,fast and enough for most cases.

HttpForm form = new HttpForm(new URI("http://localhost:8080/test/formtest.jsp"));
//Authentication form.setCredentials("user1", "password");
form.putFieldValue("input1", "your value");
HttpResponse response = form.doPost();
assertFalse(response.hasError());
assertNotNull(response.getData());
assertTrue(response.getData().contains("received " + val));

You could use flatMap. It can filter and map in one.

$scope.appIds = $scope.applicationsHere.flatMap(obj => obj.selected ? obj.id : [])

In Swift

func getFilePath() -> URL? {
    let realm = try! Realm()
    return realm.configuration.fileURL
}

Use the built-in sp_msforeachtable stored procedure.

To disable all constraints:

EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT ALL";

To enable all constraints:

EXEC sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL";

To drop all the tables:

EXEC sp_msforeachtable "DROP TABLE ?";

Here's an alternative to Arun's first solution, with a simpler Perl-like regular expression:

as.numeric(gsub("[^\\d]+", "", years, perl=TRUE))

I contacted Heroku support, and they confirmed that it is a bug with the latest gem (I am using heroku-2.26.2)

Charlie - we are aware of this issue with the 'heroku' gem and are working to fix it.

Here's the issue if you care to follow-along - https://github.com/heroku/heroku/issues/356

Downgrading to an earlier version of the 'heroku' gem should help. I've been using v2.25.0 for most of today without issue.

Downgrade with the following commands:

gem uninstall heroku

gem install heroku --version 2.25.0

If you already have multiple gems installed, you may be presented with:

Select gem to uninstall:
 1. heroku-2.25.0
 2. heroku-2.26.2
 3. All versions

Just uninstall #2 and rerun the command. Joy!

For modern browsers, use td:nth-child(2) for the second td, and td:nth-child(3) for the third. Remember that these retrieve the second and third td for every row.

If you need compatibility with IE older than version 9, use sibling combinators or JavaScript as suggested by Tim. Also see my answer to this related question for an explanation and illustration of his method.

I found this url to be very useful: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/2cdcab2e-ea49-4fd5-b2b8-13824ab4619b/help-server-not-listening-on-1433

In particular, my problem was that I did not enable the TCP/IP in Sql Server Configuration Manager->SQL Server Network Configuration->Protocols for SQLEXPRESS.

Once you open it, you have to go to the IP Addresses tab and for me, changing IPAll to TCP port 1433 and deleting the TCP Dynamic Ports value worked.

Follow the other steps to make sure 1433 is listening (Use netstat -an to make sure 0.0.0.0:1433 is LISTENING.), and that you can telnet to the port from the client machine.

Finally, I second the suggestion to remove the \SQLEXPRESS from the connection.

EDIT: I should note I am using SQL Server 2014 Express.

In the interest of coverage. I put forward an implementation using lambda expressions.

C++11

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

sort( values.begin( ), values.end( ), [ ]( const MyStruct& lhs, const MyStruct& rhs )
{
   return lhs.key < rhs.key;
});

C++14

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

sort( values.begin( ), values.end( ), [ ]( const auto& lhs, const auto& rhs )
{
   return lhs.key < rhs.key;
});

When your are three tables or more, just add union and left outer join:

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from 
(
    select category_id from a
    union
    select category_id from b
) as c
left outer join a on a.category_id = c.category_id
left outer join b on b.category_id = c.category_id

Hat tip to Adam Bien if you don't want to use createQuery with a String and want type safety:

 @PersistenceContext
 EntityManager em;

 public List<ConfigurationEntry> allEntries() {
        CriteriaBuilder cb = em.getCriteriaBuilder();
        CriteriaQuery<ConfigurationEntry> cq = cb.createQuery(ConfigurationEntry.class);
        Root<ConfigurationEntry> rootEntry = cq.from(ConfigurationEntry.class);
        CriteriaQuery<ConfigurationEntry> all = cq.select(rootEntry);
        TypedQuery<ConfigurationEntry> allQuery = em.createQuery(all);
        return allQuery.getResultList();
 }

I just want to add that this nearly identical post provides the very useful alternative of using an echo pipe if no force or quiet switch is available. For instance, I think it's the only way to bypass the Y/N prompt in this example.

Echo y|NETDOM COMPUTERNAME WorkComp /Add:Work-Comp

In a general sense you should first look at your command switches for /f, /q, or some variant thereof (for example, Netdom RenameComputer uses /Force, not /f). If there is no switch available, then use an echo pipe.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

Is EmailHandler really the full name of your servlet class, i.e. it's not in a package like com.something.EmailHandler? It has to be fully-qualified in web.xml.

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

You can also use a regular expression as a field separator. The following will print "bar" by using a regular expression to set the number "10" as a separator.

echo "foo 10 bar" | awk -F'[0-9][0-9]' '{print $2}'

A bit cheesy, but if you use a mac you can pass a terminal command to the console from python.

Try typing the following in the terminal:

$ say 'hello world' 

And there will be a voice from the mac that will speak that. From python such a thing is relatively easy:

import os
os.system("echo 'hello world'")
os.system("say 'hello world'") 

Like this?

 System.out.println(Name + " " + Income);

Simple Answer: NO

Well, at least a naming convention as such encouraged by Oracle or community, no, however, basically you have to be aware of following the rules and limits for identifiers, such as indicated in MySQL documentation: https://dev.mysql.com/doc/refman/8.0/en/identifiers.html

About the naming convention you follow, I think it is ok, just the number 5 is a little bit unnecesary, I think most visual tools for managing databases offer a option for sorting column names (I use DBeaver, and it have it), so if the purpouse is having a nice visual presentation of your table you can use this option I mention.

By personal experience, I would recommed this:

• Use lower case. This almost ensures interoperability when you migrate your databases from one server to another. Sometimes the lower_case_table_names is not correctly configured and your server start throwing errors just by simply unrecognizing your camelCase or PascalCase standard (case sensitivity problem).
• Short names. Simple and clear. The most easy and fast is identify your table or columns, the better. Trust me, when you make a lot of different queries in a short amount of time is better having all simple to write (and read).
• Avoid prefixes. Unless you are using the same database for tables of different applications, don't use prefixes. This only add more verbosity to your queries. There are situations when this could be useful, for example, when you want to indentify primary keys and foreign keys, that usually table names are used as prefix for id columns.
• Use underscores for separating words. If you still want to use more than one word for naming a table, column, etc., so use underscores for separating_the_words, this helps for legibility (your eyes and your stressed brain are going to thank you).
• Be consistent. Once you have your own standard, follow it. Don´t be the person that create the rules and is the first who breaking them, that is shameful.

And what about the "Plural vs Singular" naming? Well, this is most a situation of personal preferences. In my case I try to use plural names for tables because I think a table as a collection of elements or a package containig elements, so a plural name make sense for me; and singular names for columns because I see columns as attributes that describe singularly to those table elements.

Well there are a few ways to go about this depending on the intended behavior, but this link should give you all the best solutions and not surprisingly is from Dianne Hackborn

http://groups.google.com/group/android-developers/browse_thread/thread/d2a5c203dad6ec42

Essentially you have the following options

• Use a name for your initial back stack state and use FragmentManager.popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE).
• Use FragmentManager.getBackStackEntryCount()/getBackStackEntryAt().getId() to retrieve the ID of the first entry on the back stack, and FragmentManager.popBackStack(int id, FragmentManager.POP_BACK_STACK_INCLUSIVE).
• FragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE) is supposed to pop the entire back stack... I think the documentation for that is just wrong. (Actually I guess it just doesn't cover the case where you pass in POP_BACK_STACK_INCLUSIVE),

You can take a look at the add(int index, E element):

Inserts the specified element at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Once you add you can then check the size of the ArrayList and remove the ones at the end.

I am pretty bad at html but I used   between the buttons and it worked well.

This is an addendum to @endy-tjahjono's solution.

I ended up not being able to get the value of uploadme from the scope. Even though uploadme in the HTML was visibly updated by the directive, I could still not access its value by $scope.uploadme. I was able to set its value from the scope, though. Mysterious, right..?

As it turned out, a child scope was created by the directive, and the child scope had its own uploadme.

The solution was to use an object rather than a primitive to hold the value of uploadme.

In the controller I have:

$scope.uploadme = {};
$scope.uploadme.src = "";

and in the HTML:

 <input type="file" fileread="uploadme.src"/>
 <input type="text" ng-model="uploadme.src"/>

There are no changes to the directive.

Now, it all works like expected. I can grab the value of uploadme.src from my controller using $scope.uploadme.

I'm using VS SSDT on Windows. I started a project and set up local version control. I later installed git and and created a Github repo. Once I had my repo on Github I grabbed the URL and put that into VS when it asked me for the URL when I hit the "publish to Github" button.

This is called finding the k-th order statistic. There's a very simple randomized algorithm (called quickselect) taking O(n) average time, O(n^2) worst case time, and a pretty complicated non-randomized algorithm (called introselect) taking O(n) worst case time. There's some info on Wikipedia, but it's not very good.

Everything you need is in these powerpoint slides. Just to extract the basic algorithm of the O(n) worst-case algorithm (introselect):

Select(A,n,i):
    Divide input into ?n/5? groups of size 5.

    /* Partition on median-of-medians */
    medians = array of each group’s median.
    pivot = Select(medians, ?n/5?, ?n/10?)
    Left Array L and Right Array G = partition(A, pivot)

    /* Find ith element in L, pivot, or G */
    k = |L| + 1
    If i = k, return pivot
    If i < k, return Select(L, k-1, i)
    If i > k, return Select(G, n-k, i-k)

It's also very nicely detailed in the Introduction to Algorithms book by Cormen et al.

The [] operator is called an indexer. You can provide indexers that take an integer, a string, or any other type you want to use as a key. The syntax is straightforward, following the same principles as property accessors.

For example, in your case where an int is the key or index:

public int this[int index]
{
    get => GetValue(index);
}

You can also add a set accessor so that the indexer becomes read and write rather than just read-only.

public int this[int index]
{
    get => GetValue(index);
    set => SetValue(index, value);
}

If you want to index using a different type, you just change the signature of the indexer.

public int this[string index]
...

Node-ETL package is enough for all BI processing.

npm install node-etl; 

Then :

var ETL=require('node-etl');
var output=ETL.extract('./data.csv',{
              headers:["a","b","c","d"],
              ignore:(line,index)=>index!==0, //ignore first line
 });

This appears to be a bug in the SelectExtensions class as it will only check the ViewData rather than the model for the selected item. So the trick is to copy the selected item from the model into the ViewData collection under the name of the property.

This is taken from the answer I gave on the MVC forums, I also have a more complete answer in a blog post that uses Kazi's DropDownList attribute...

Given a model

public class ArticleType
{
   public Guid Id { get; set; }
   public string Description { get; set; }
}

public class Article
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public ArticleType { get; set; }
}

and a basic view model of

public class ArticleModel
{
     public Guid Id { get; set; }
     public string Name { get; set; }

     [UIHint("DropDownList")]
     public Guid ArticleType { get; set; }
}

Then we write a DropDownList editor template as follows..

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<script runat="server">  
    IEnumerable<SelectListItem> GetSelectList()
    {
        var metaData = ViewData.ModelMetadata;
        if (metaData == null)
        {
            return null;
        }

        var selected = Model is SelectListItem ? ((SelectListItem) Model).Value : Model.ToString();
        ViewData[metaData.PropertyName] = selected;

        var key = metaData.PropertyName + "List";
        return (IEnumerable<SelectListItem>)ViewData[key];
    }
</script>
<%= Html.DropDownList(null, GetSelectList()) %>

This will also work if you change ArticleType in the view model to a SelectListItem, though you do have to implement a type converter as per Kazi's blog and register it to force the binder to treat this as a simple type.

In your controller we then have...

public ArticleController 
{
     ...
     public ActionResult Edit(int id)
     {
          var entity = repository.FindOne<Article>(id);
          var model = builder.Convert<ArticleModel>(entity);

          var types = repository.FindAll<ArticleTypes>();
          ViewData["ArticleTypeList"] = builder.Convert<SelectListItem>(types);

          return VIew(model);
     }
     ...
}

Since Express 4.0, there's a dedicated sendStatus function:

res.sendStatus(404);

If you're using an earlier version of Express, use the status function instead.

res.status(404).send('Not found');

Try this:

;WITH CTE
AS
(
    SELECT DISTINCT
        M1.Product_ID Group_ID,
        M1.Product_ID
    FROM matches M1
        LEFT JOIN matches M2
            ON M1.Product_Id = M2.matching_Product_Id
    WHERE M2.matching_Product_Id IS NULL
    UNION ALL
    SELECT
        C.Group_ID,
        M.matching_Product_Id
    FROM CTE C
        JOIN matches M
            ON C.Product_ID = M.Product_ID
)
SELECT * FROM CTE ORDER BY Group_ID

You can use OPTION(MAXRECURSION n) to control recursion depth.

SQL FIDDLE DEMO

If you recently added a collection to your project when this started to occur, the problem may be caused by two collections which have the same CollectionDataContract attribute:

[CollectionDataContract(Name="AItems", ItemName="A")]
public class CollectionA : List<A> { }

[CollectionDataContract(Name="AItems", ItemName="A")]  // Wrong
public class CollectionB : List<B> { }

I fixed the error by sweeping through my project and ensuring that every Name and ItemName attribute was unique:

[CollectionDataContract(Name="AItems", ItemName="A")]
public class CollectionA : List<A> { }

[CollectionDataContract(Name="BItems", ItemName="B")]  // Corrected
public class CollectionB : List<B> { }

Then I refreshed the service reference and everything worked again.

I understand the accepted answer, and have up-voted it but thought I'd dump my laymen's answer here...

Creating a hash

1. The salt is randomly generated using the function Rfc2898DeriveBytes which generates a hash and a salt. Inputs to Rfc2898DeriveBytes are the password, the size of the salt to generate and the number of hashing iterations to perform. https://msdn.microsoft.com/en-us/library/h83s4e12(v=vs.110).aspx
2. The salt and the hash are then mashed together(salt first followed by the hash) and encoded as a string (so the salt is encoded in the hash). This encoded hash (which contains the salt and hash) is then stored (typically) in the database against the user.

Checking a password against a hash

To check a password that a user inputs.

1. The salt is extracted from the stored hashed password.
2. The salt is used to hash the users input password using an overload of Rfc2898DeriveBytes which takes a salt instead of generating one. https://msdn.microsoft.com/en-us/library/yx129kfs(v=vs.110).aspx
3. The stored hash and the test hash are then compared.

The Hash

Under the covers the hash is generated using the SHA1 hash function (https://en.wikipedia.org/wiki/SHA-1). This function is iteratively called 1000 times (In the default Identity implementation)

Why is this secure

• Random salts means that an attacker can’t use a pre-generated table of hashs to try and break passwords. They would need to generate a hash table for every salt. (Assuming here that the hacker has also compromised your salt)
• If 2 passwords are identical they will have different hashes. (meaning attackers can’t infer ‘common’ passwords)
• Iteratively calling SHA1 1000 times means that the attacker also needs to do this. The idea being that unless they have time on a supercomputer they won’t have enough resource to brute force the password from the hash. It would massively slow down the time to generate a hash table for a given salt.

You can force to revert your local directory to svn.

 svn revert -R your_local_path

Use Ctrl-N to get a list of word suggestions while in insert mode. Type :help i_CTRL-N to see Vim's documentation on this functionality.

Here is an example of importing the Python dictionary into Vim.

I'm using this alias for checking out a branch in a temporary directory:

[alias]
    cot = "!TEMP=$(mktemp -d); f() { git worktree prune && git worktree add $TEMP $1 && zsh -c \"cd $TEMP; zsh\";}; f" # checkout branch in temporary directory

Usage:

git cot mybranch

You are then dropped in a new shell in the temporary directory where you can work on the branch. You can even use git commands in this directory.

When you're done, delete the directory and run:

git worktree prune

This is also done automatically in the alias, before adding a new worktree.

In my case, there was a mistake in the list of the parameters was not well formed. So make sure the parameters are well formed. For e.g. correct format of parameters

data: {'reporter': reporter,'partner': partner,'product': product}

Here are 4 methods:

var x = 34
var s = String(x)
var ss = "\(x)"
var sss = toString(x)
var ssss = x.description

I can imagine that some people will have an issue with ss. But if you were looking to build a string containing other content then why not.

you can enter the jdk path required as th full path for java.exe in sql developer for oracle 11g.

I found the jdk at the following path in my system.

c:\app\sony\product\11.0.0\db_1\jdk

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

Solution

Use usecols and names parameters

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

Additional reading

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

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

So that you can retrieve your data by

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

instead of

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

Explain

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

For legend labels can use something like below. Legendlabels are the plot lines saved. modFreq are where the name of the actual labels corresponding to the plot lines. Then the third parameter is the location of the legend. Lastly, you can pass in any arguments as I've down here but mainly need the first three. Also, you are supposed to if you set the labels correctly in the plot command. To just call legend with the location parameter and it finds the labels in each of the lines. I have had better luck making my own legend as below. Seems to work in all cases where have never seemed to get the other way going properly. If you don't understand let me know:

legendLabels = []
for i in range(modSize):
    legendLabels.append(ax.plot(x,hstack((array([0]),actSum[j,semi,i,semi])), color=plotColor[i%8], dashes=dashes[i%4])[0]) #linestyle=dashs[i%4]       
legArgs = dict(title='AM Templates (Hz)',bbox_to_anchor=[.4,1.05],borderpad=0.1,labelspacing=0,handlelength=1.8,handletextpad=0.05,frameon=False,ncol=4, columnspacing=0.02) #ncol,numpoints,columnspacing,title,bbox_transform,prop
leg = ax.legend(tuple(legendLabels),tuple(modFreq),'upper center',**legArgs)
leg.get_title().set_fontsize(tick_size)

You can also use the leg to change fontsizes or nearly any parameter of the legend.

Global title as stated in the above comment can be done with adding text per the link provided: http://matplotlib.sourceforge.net/examples/pylab_examples/newscalarformatter_demo.html

f.text(0.5,0.975,'The new formatter, default settings',horizontalalignment='center',
       verticalalignment='top')

the solution from millhouse is not working anymore with recent version of mockito

This solution work with java 8 and mockito 2.2.9

where ArgumentMatcher is an instanceof org.mockito.ArgumentMatcher

public class ClassOrSubclassMatcher<T> implements ArgumentMatcher<Class<T>> {

   private final Class<T> targetClass;

    public ClassOrSubclassMatcher(Class<T> targetClass) {
        this.targetClass = targetClass;
    }

    @Override
    public boolean matches(Class<T> obj) {
        if (obj != null) {
            if (obj instanceof Class) {
                return targetClass.isAssignableFrom( obj);
            }
        }
        return false;
    }
}

And the use

when(a.method(ArgumentMatchers.argThat(new ClassOrSubclassMatcher<>(A.class)))).thenReturn(b);

Just use JSON.stringify(object). It's built into Javascript and can therefore also be used within Typescript.

I do not like transformations to have any more info than needed. So instead of restating the keys, I simply state the condition and intention. It is much easier to see the intention when done like this, at least IMO. Also, I try and put all the xdt attributes first to indicate to the reader, these are transformations and not new things being defined.

<appSettings>
  <add xdt:Locator="Condition(@key='developmentModeUserId')" xdt:Transform="Remove" />
  <add xdt:Locator="Condition(@key='developmentMode')" xdt:Transform="SetAttributes"
       value="false"/>
</appSettings>

In the above it is much easier to see that the first one is removing the element. The 2nd one is setting attributes. It will set/replace any attributes you define here. In this case it will simply set value to false.

if you call pyplot as plt

frameon=False is to remove the border around the legend

and '' is passing the information that no variable should be in the legend

You can use either foreign key on many side of OneToMany relation (i.e. ManyToOne relation) or use ManyToMany (on any side) with unique constraint.

Add programatically noborder class to specific row to hide it

<style>
     .noborder
      {
        border:none;
      }
    </style>

<table>

    <tr>
       <th>heading1</th>
       <th>heading2</th>
    </tr>


    <tr>
       <td>content1</td>
       <td>content2</td>
    </tr>
    /*no border for this row */
    <tr class="noborder">
       <td>content1</td>
       <td>content2</td>
    </tr>

</table>

this would be good log4j error/exception logging - readable by splunk/other logging/monitoring s/w. everything is form of key-value pair. log4j would get the stack trace from Exception obj e

    try {
          ---
          ---
    } catch (Exception e) {
        log.error("api_name={} method={} _message=\"error description.\" msg={}", 
                  new Object[]{"api_name", "method_name", e.getMessage(), e});
    }

The other Answers are correct, especially this one by Stephen C.

Reaching Outside Java

Generating a UUID value within Java is limited to Version 4 (random) because of security concerns.

If you want other versions of UUIDs, one avenue is to have your Java app reach outside the JVM to generate UUIDs by calling on:

• Command-line utility
  Bundled with nearly every operating system.
  For example, uuidgen found in Mac OS X, BSD, and Linux.
• Database server
  Use JDBC to retrieve a UUID generated on the database server.
  For example, the uuid-ossp extension often bundled with Postgres. That extension can generates Versions 1, 3, and 4 values and additionally a couple variations:
  • uuid_generate_v1mc() – generates a version 1 UUID but uses a random multicast MAC address instead of the real MAC address of the computer.
  • uuid_generate_v5(namespace uuid, name text) – generates a version 5 UUID, which works like a version 3 UUID except that SHA-1 is used as a hashing method.
• Web Service
  For example, UUID Generator creates Versions 1 & 3 as well as nil values and GUID.

Try to use datepicker/ timepicker instead of datetimepicker like:

replace:

$('#datetimepicker1').datetimepicker();

with:

$('#datetimepicker1').datepicker(); // or timepicker for time picker

The best practice for this, in my opinion is:

TimeUnit.DAYS.toMillis(1);     // 1 day to milliseconds.
TimeUnit.MINUTES.toMillis(23); // 23 minutes to milliseconds.
TimeUnit.HOURS.toMillis(4);    // 4 hours to milliseconds.
TimeUnit.SECONDS.toMillis(96); // 96 seconds to milliseconds.

Tested and works in Opera 12.17, firefox 30, Internet Explorer 9 and chrome 26.0.1410.64

document.oncontextmenu =function( evt ){

^ BRANCH Selector
git checkout HEAD^2
Selects the 2nd branch of a (merge) commit by moving onto the selected branch (one step backwards on the commit-tree)

~ COMMIT Selector
git checkout HEAD~2
Moves 2 commits backwards on the default/selected branch

Defining both ~ and ^ relative refs as PARENT selectors is far the dominant definition published everywhere on the internet I have come across so far - including the official Git Book. Yes they are PARENT selectors, but the problem with this "explanation" is that it is completely against our goal: which is how to distinguish the two... :)

The other problem is when we are encouraged to use the ^ BRANCH selector for COMMIT selection (aka HEAD^ === HEAD~).
Again, yes, you can use it this way, but this is not its designed purpose. The ^ BRANCH selector's backwards move behaviour is a side effect not its purpose.

At merged commits only, can a number be assigned to the ^ BRANCH selector. Thus its full capacity can only be utilised where there is a need for selecting among branches. And the most straightforward way to express a selection in a fork is by stepping onto the selected path / branch - that's for the one step backwards on the commit-tree. It is a side effect only, not its main purpose.

You can use the -f operator

$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)

If you want to stick with the same sort of loop then this will work:

Option Explicit

Sub selectColumns()

Dim topSelection As Integer
Dim endSelection As Integer
topSelection = 2
endSelection = 10

Dim columnSelected As Integer
columnSelected = 1
Do
   With Excel.ThisWorkbook.ActiveSheet
        .Range(.Cells(columnSelected, columnSelected), .Cells(endSelection, columnSelected)).Select
   End With
   columnSelected = columnSelected + 1
Loop Until columnSelected > 10

End Sub

EDIT

If in reality you just want to loop through every cell in an area of the spreadsheet then use something like this:

Sub loopThroughCells()

'=============
'this is the starting point
Dim rwMin As Integer
Dim colMin As Integer
rwMin = 2
colMin = 2
'=============

'=============
'this is the ending point
Dim rwMax As Integer
Dim colMax As Integer
rwMax = 10
colMax = 5
'=============

'=============
'iterator
Dim rwIndex As Integer
Dim colIndex As Integer
'=============

For rwIndex = rwMin To rwMax
        For colIndex = colMin To colMax
            Cells(rwIndex, colIndex).Select
        Next colIndex
Next rwIndex

End Sub

I had the same issue:

raise SSLError(e)
requests.exceptions.SSLError: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol

I had fiddler running, I stopped fiddler capture and did not see this error. Could be because of fiddler.

Don't know how you want to format it, but you can do:

print("Created at %s:%s" % (t1.hour, t1.minute))

for example.

Yes it will return null if it's not present you can try this below in the demo. Both will return true. The first elements exists the second doesn't.

Demo

Html

<div id="xx"></div>

Javascript:

   if (document.getElementById('xx') !=null) 
     console.log('it exists!');

   if (document.getElementById('xxThisisNotAnElementOnThePage') ==null) 
     console.log('does not exist!');

If you have tried .attr("value", "") and didn't work, don't panic (like I did)

just do .val("") instead, and will work fine

This is concerning "Build Solution" option only.

I got totally fed up with Visual Studio's inability to really clean solutions and wrote this little tool that will do it for you.

Close your solution in VS first and drag its folder from Windows Explorer into this app or into its icon. Depending on the setting at the bottom of its window, it can also remove additional stuff, that will help if you try to manually upload your solution to GitHub or share it with someone else:

In a nutshell, it will place all "Debug" folders, Intellisense, and other caches that can be rebuilt by VS into Recycle Bin for you.

As it turns out, the problem wasn't actually a looping chain of synonyms, but the fact that the synonym was pointing to a view that did not exist.

Oracle apparently errors out as a looping chain in this condition.

If you are wanting to just copy the whole column, you can simplify the code a lot by doing something like this:

Sub CopyCol()

    Sheets("Sheet1").Columns(1).Copy

    Sheets("Sheet2").Columns(2).PasteSpecial xlPasteValues

End Sub

Or

Sub CopyCol()

    Sheets("Sheet1").Columns("A").Copy

    Sheets("Sheet2").Columns("B").PasteSpecial xlPasteValues

End Sub

Or if you want to keep the loop

Public Sub CopyrangeA()

    Dim firstrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    firstrowDB = 1
    arr1 = Array("BJ", "BK")
    arr2 = Array("A", "B")

    For i = LBound(arr1) To UBound(arr1)

        Sheets("Sheet1").Columns(arr1(i)).Copy

        Sheets("Sheet2").Columns(arr2(i)).PasteSpecial xlPasteValues

    Next
    Application.CutCopyMode = False

End Sub

You can wrote **_bold and italic_** and re-style it to underlined text, like this:

strong>em,
em>strong,
b>i,
i>b {
    font-style:normal;
    font-weight:normal;
    text-decoration:underline;
}

This is fairly simple with the callback syntax of attr:

$("#product1 :checkbox").click(function(){
  $(this)
   .closest('tr') // find the parent row
       .find(":input[type='text']") // find text elements in that row
           .attr('disabled',function(idx, oldAttr) {
               return !oldAttr; // invert disabled value
           })
           .toggleClass('disabled') // enable them
       .end() // go back to the row
       .siblings() // get its siblings
           .find(":input[type='text']") // find text elements in those rows
               .attr('disabled',function(idx, oldAttr) {
                   return !oldAttr; // invert disabled value
               })
               .removeClass('disabled'); // disable them
});

In Python, without external dependencies, it is something like this (untested):

with open("filename") as origin:
    for line in origin:
        if not "something" in line:
           continue
        try:
            print line.split('"')[1]
        except IndexError:
            print

Change your declarations to this:

double lateFee = 0.0;
double monthlyCharge = 0.0;
double annualRate = 0.0;

The error is caused because there is at least one path through your code where these variables end up not getting set to anything.

A database is the computerized logical representation of a conceptual (or business) model, consisting of a set of informal business rules. These rules are the user-understood meaning of the data. Because computers comprehend only formal representations, business rules cannot be represented directly in a database. They must be mapped to a formal representation, a logical model, which consists of a set of integrity constraints. These constraints — the database schema — are the logical representation in the database of the business rules and, therefore, are the DBMS-understood meaning of the data. It follows that if the DBMS is unaware of and/or does not enforce the full set of constraints representing the business rules, it has an incomplete understanding of what the data means and, therefore, cannot guarantee (a) its integrity by preventing corruption, (b) the integrity of inferences it makes from it (that is, query results) — this is another way of saying that the DBMS is, at best, incomplete.

Note: The DBMS-“understood” meaning — integrity constraints — is not identical to the user-understood meaning — business rules — but, the loss of some meaning notwithstanding, we gain the ability to mechanize logical inferences from the data.

"An Old Class of Errors" by Fabian Pascal

you can use "__range" for example :

from datetime import datetime
start_date=datetime(2009, 12, 30)
end_end=datetime(2020,12,30)
Sample.objects.filter(date__range=[start_date,end_date])

No you don't need to check if you're in the main thread. Here is how you can do this in Swift:

runThisInMainThread { () -> Void in
    runThisInMainThread { () -> Void in
        // No problem
    }
}

func runThisInMainThread(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

Its included as a standard function in my repo, check it out: https://github.com/goktugyil/EZSwiftExtensions

Here is the solution:

d3.select("svg").remove();

This is a remove function provided by D3.js.

Using regex:

str = 'string'
n = 1  #to remove first n characters

str[/.{#{str.size-n}}\z/] #=> "tring"

None of the above worked on Sublime Text 3 on Windows 10, Ctrl + Shift + ' with the Emmet Sublime Text 3 plugin works great and was the only working solution for me. Ctrl + Shift + T re-opens the last closed item and to my knowledge of Sublime, has done so since early builds of ST3 or late builds of ST2.

If you add all your events with this snippet of code:

//put this somewhere in your JavaScript:
HTMLElement.prototype.addEvent = function(event, callback){
  if(!this.events)this.events = {};
  if(!this.events[event]){
    this.events[event] = [];
    var element = this;
    this['on'+event] = function(e){
      var events = element.events[event];
      for(var i=0;i<events.length;i++){
        events[i](e||event);
      }
    }
  }
  this.events[event].push(callback);
}
//use like this:
element.addEvent('change', function(e){...});

then you can just use element.on<EVENTNAME>() where <EVENTNAME> is the name of your event, and that will call all events with <EVENTNAME>

I got this issue because I was lazily defining a variable in my .m outside of a method, then in another .m file I was defining another variable with the same name outside a method. This was causing a global variable name duplicate issue.

The calculated column trick is widely known as a "nullbuster"; my notes credit Steve Kass:

CREATE TABLE dupNulls (
pk int identity(1,1) primary key,
X  int NULL,
nullbuster as (case when X is null then pk else 0 end),
CONSTRAINT dupNulls_uqX UNIQUE (X,nullbuster)
)

In pre Sql 2008 By taking out the date part:

GROUP BY CONVERT(CHAR(8),DateTimeColumn,10)

If your widget is a Button:

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:weightSum="2"
    android:orientation="horizontal">
    <Button android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="somebutton"/>

    <TextView android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"/>
</LinearLayout>

I'm assuming you want your widget to take up one half, and another widget to take up the other half. The trick is using a LinearLayout, setting layout_width="fill_parent" on both widgets, and setting layout_weight to the same value on both widgets as well. If there are two widgets, both with the same weight, the LinearLayout will split the width between the two widgets.

NOTE : This solution is broken in iOS 8. I will post new solution ASAP.

I am going to answer here using storyboard but it is also possible without storyboard.

1. Init: Create two UIViewController in storyboard.

   • lets say FirstViewController which is normal and SecondViewController which will be the popup.

2. Modal Segue: Put UIButton in FirstViewController and create a segue on this UIButton to SecondViewController as modal segue.

3. Make Transparent: Now select UIView (UIView Which is created by default with UIViewController) of SecondViewController and change its background color to clear color.

4. Make background Dim: Add an UIImageView in SecondViewController which covers whole screen and sets its image to some dimmed semi transparent image. You can get a sample from here : UIAlertView Background Image

5. Display Design: Now add an UIView and make any kind of design you want to show. Here is a screenshot of my storyboard

   • Here I have add segue on login button which open SecondViewController as popup to ask username and password

6. Important: Now that main step. We want that SecondViewController doesn't hide FirstViewController completely. We have set clear color but this is not enough. By default it adds black behind model presentation so we have to add one line of code in viewDidLoad of FirstViewController. You can add it at another place also but it should run before segue.

   [self setModalPresentationStyle:UIModalPresentationCurrentContext];

7. Dismiss: When to dismiss depends on your use case. This is a modal presentation so to dismiss we do what we do for modal presentation:

   [self dismissViewControllerAnimated:YES completion:Nil];

Thats all.....

Any kind of suggestion and comment are welcome.

Demo : You can get demo source project from Here : Popup Demo

NEW : Someone have done very nice job on this concept : MZFormSheetController
New : I found one more code to get this kind of function : KLCPopup

iOS 8 Update : I made this method to work with both iOS 7 and iOS 8

+ (void)setPresentationStyleForSelfController:(UIViewController *)selfController presentingController:(UIViewController *)presentingController
{
    if (iOSVersion >= 8.0)
    {
        presentingController.providesPresentationContextTransitionStyle = YES;
        presentingController.definesPresentationContext = YES;

        [presentingController setModalPresentationStyle:UIModalPresentationOverCurrentContext];
    }
    else
    {
        [selfController setModalPresentationStyle:UIModalPresentationCurrentContext];
        [selfController.navigationController setModalPresentationStyle:UIModalPresentationCurrentContext];
    }
}

Can use this method inside prepareForSegue deligate like this

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    PopUpViewController *popup = segue.destinationViewController;
    [self setPresentationStyleForSelfController:self presentingController:popup]
}

junit4 require that test classname should be use Test as suffix.

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

Assuming that you have a collection ${roles} of the elements to put in the combo, and ${selected} the selected element, It would go like this:

<select name='role'>
    <option value="${selected}" selected>${selected}</option>
    <c:forEach items="${roles}" var="role">
        <c:if test="${role != selected}">
            <option value="${role}">${role}</option>
        </c:if>
    </c:forEach>
</select>

UPDATE (next question)

You are overwriting the attribute "productSubCategoryName". At the end of the for loop, the last productSubCategoryName.

Because of the limitations of the expression language, I think the best way to deal with this is to use a map:

Map<String,Boolean> map = new HashMap<String,Boolean>();
for(int i=0;i<userProductData.size();i++){
    String productSubCategoryName=userProductData.get(i).getProductSubCategory();
    System.out.println(productSubCategoryName);
    map.put(productSubCategoryName, true);
}
request.setAttribute("productSubCategoryMap", map);

And then in the JSP:

<select multiple="multiple" name="prodSKUs">
    <c:forEach items="${productSubCategoryList}" var="productSubCategoryList">
        <option value="${productSubCategoryList}" ${not empty productSubCategoryMap[productSubCategoryList] ? 'selected' : ''}>${productSubCategoryList}</option>
    </c:forEach>
</select>

The a.download is not supported by IE. At least at the HTML5 "supported" pages. :(

You can use reorder:

qplot(reorder(factor(cyl),factor(cyl),length),data=mtcars,geom="bar")

Edit:

To have the tallest bar at the left, you have to use a bit of a kludge:

qplot(reorder(factor(cyl),factor(cyl),function(x) length(x)*-1),
   data=mtcars,geom="bar")

I would expect this to also have negative heights, but it doesn't, so it works!

Both works fine. But according to the Apache docs you should avoid using mod_rewrite for simple redirections, and use Redirect instead. So according to them, you should preferably do:

<VirtualHost *:80>
    ServerName www.example.com
    Redirect / https://www.example.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.com
    # ... SSL configuration goes here
</VirtualHost>

The first / after Redirect is the url, the second part is where it should be redirected.

You can also use it to redirect URLs to a subdomain: Redirect /one/ http://one.example.com/

The curl installed by default in Debian supports HTTPS since a great while back. (a long time ago there were two separate packages, one with and one without SSL but that's not the case anymore)

OPTIONS /path

You can send an OPTIONS request with curl like this:

curl -i -X OPTIONS http://example.org/path

You may also use -v instead of -i to see more output.

OPTIONS *

To send a plain * (instead of the path, see RFC 7231) with the OPTIONS method, you need curl 7.55.0 or later as then you can run a command line like:

curl -i --request-target "*" -X OPTIONS http://example.org

• Search and download the appropriate vcruntime140.dll file for your system from the internet (32 / 64 bit version) , and replace it with the vcruntime140.dll file in the folder ~\Android\Sdk\emulator

• Try step 1

• If you get error about vcruntime140_1 , change the file name as vcruntime140_1.dll ,try step 1

3. If you get error about msvcp140.dll

• Search and download the appropriate msvcp140.dll file for your system from the internet (32 / 64 bit version)
• Replace the file in the folder C:\Windows\System32 with file msvcp140.dll
• Try step 1

If it runs , you can run it from Android Studio also.

You can do something like this, very simple and efficient solution: What i did was actually use a parameter instead of basic placeholder, created a SqlParameter object and used another existing execution method. For e.g in your scenario:

string sql = "INSERT INTO mssqltable (varbinarycolumn) VALUES (@img)";
SqlParameter param = new SqlParameter("img", arraytoinsert); //where img is your parameter name in the query
ExecuteStoreCommand(sql, param);

This should work like a charm, provided you have an open sql connection established.

The standard MIME type is application/pdf. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.

MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.

The use of x-pdf predates the standardization of the MIME type for PDF. MIME types in the x- namespace are considered experimental, just as those in the vnd. namespace are considered vendor-specific. x-pdf might be used for compatibility with old software.

An ellipsis is three periods in a row...

The TextView will use an ellipsis when it cannot expand to show all of its text. The attribute ellipsized sets the position of the three dots if it is necessary.

Insertion

Sequence Containers

• vector: The functions insert, emplace_back, emplace, push_back cause reallocation if the new size is greater than the old capacity. Reallocation invalidates all the references, pointers, and iterators referring to the elements in the sequence. If no reallocation happens, all the iterators and references before the insertion point remain valid. [26.3.11.5/1]
  With respect to the reserve function, reallocation invalidates all the references, pointers, and iterators referring to the elements in the sequence. No reallocation shall take place during insertions that happen after a call to reserve() until the time when an insertion would make the size of the vector greater than the value of capacity(). [26.3.11.3/6]

• deque: An insertion in the middle of the deque invalidates all the iterators and references to elements of the deque. An insertion at either end of the deque invalidates all the iterators to the deque, but has no effect on the validity of references to elements of the deque. [26.3.8.4/1]

• list: Does not affect the validity of iterators and references. If an exception is thrown there are no effects. [26.3.10.4/1].
  The insert, emplace_front, emplace_back, emplace, push_front, push_back functions are covered under this rule.

• forward_list: None of the overloads of insert_after shall affect the validity of iterators and references [26.3.9.5/1]

• array: As a rule, iterators to an array are never invalidated throughout the lifetime of the array. One should take note, however, that during swap, the iterator will continue to point to the same array element, and will thus change its value.

Associative Containers

• All Associative Containers: The insert and emplace members shall not affect the validity of iterators and references to the container [26.2.6/9]

Unordered Associative Containers

• All Unordered Associative Containers: Rehashing invalidates iterators, changes ordering between elements, and changes which buckets elements appear in, but does not invalidate pointers or references to elements. [26.2.7/9]
  The insert and emplace members shall not affect the validity of references to container elements, but may invalidate all iterators to the container. [26.2.7/14]
  The insert and emplace members shall not affect the validity of iterators if (N+n) <= z * B, where N is the number of elements in the container prior to the insert operation, n is the number of elements inserted, B is the container’s bucket count, and z is the container’s maximum load factor. [26.2.7/15]

• All Unordered Associative Containers: In case of a merge operation (e.g., a.merge(a2)), iterators referring to the transferred elements and all iterators referring to a will be invalidated, but iterators to elements remaining in a2 will remain valid. (Table 91 — Unordered associative container requirements)

Container Adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Erasure

Sequence Containers

• vector: The functions erase and pop_back invalidate iterators and references at or after the point of the erase. [26.3.11.5/3]

• deque: An erase operation that erases the last element of a deque invalidates only the past-the-end iterator and all iterators and references to the erased elements. An erase operation that erases the first element of a deque but not the last element invalidates only iterators and references to the erased elements. An erase operation that erases neither the first element nor the last element of a deque invalidates the past-the-end iterator and all iterators and references to all the elements of the deque. [ Note: pop_front and pop_back are erase operations. —end note ] [26.3.8.4/4]

• list: Invalidates only the iterators and references to the erased elements. [26.3.10.4/3]. This applies to erase, pop_front, pop_back, clear functions.
  remove and remove_if member functions: Erases all the elements in the list referred by a list iterator i for which the following conditions hold: *i == value, pred(*i) != false. Invalidates only the iterators and references to the erased elements [26.3.10.5/15].
  unique member function - Erases all but the first element from every consecutive group of equal elements referred to by the iterator i in the range [first + 1, last) for which *i == *(i-1) (for the version of unique with no arguments) or pred(*i, *(i - 1)) (for the version of unique with a predicate argument) holds. Invalidates only the iterators and references to the erased elements. [26.3.10.5/19]

• forward_list: erase_after shall invalidate only iterators and references to the erased elements. [26.3.9.5/1].
  remove and remove_if member functions - Erases all the elements in the list referred by a list iterator i for which the following conditions hold: *i == value (for remove()), pred(*i) is true (for remove_if()). Invalidates only the iterators and references to the erased elements. [26.3.9.6/12].
  unique member function - Erases all but the first element from every consecutive group of equal elements referred to by the iterator i in the range [first + 1, last) for which *i == *(i-1) (for the version with no arguments) or pred(*i, *(i - 1)) (for the version with a predicate argument) holds. Invalidates only the iterators and references to the erased elements. [26.3.9.6/16]

• All Sequence Containers: clear invalidates all references, pointers, and iterators referring to the elements of a and may invalidate the past-the-end iterator (Table 87 — Sequence container requirements). But for forward_list, clear does not invalidate past-the-end iterators. [26.3.9.5/32]

• All Sequence Containers: assign invalidates all references, pointers and iterators referring to the elements of the container. For vector and deque, also invalidates the past-the-end iterator. (Table 87 — Sequence container requirements)

Associative Containers

• All Associative Containers: The erase members shall invalidate only iterators and references to the erased elements [26.2.6/9]

• All Associative Containers: The extract members invalidate only iterators to the removed element; pointers and references to the removed element remain valid [26.2.6/10]

Container Adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

General container requirements relating to iterator invalidation:

• Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [26.2.1/12]

• no swap() function invalidates any references, pointers, or iterators referring to the elements of the containers being swapped. [ Note: The end() iterator does not refer to any element, so it may be invalidated. —end note ] [26.2.1/(11.6)]

As examples of the above requirements:

• transform algorithm: The op and binary_op functions shall not invalidate iterators or subranges, or modify elements in the ranges [28.6.4/1]

• accumulate algorithm: In the range [first, last], binary_op shall neither modify elements nor invalidate iterators or subranges [29.8.2/1]

• reduce algorithm: binary_op shall neither invalidate iterators or subranges, nor modify elements in the range [first, last]. [29.8.3/5]

and so on...

Instead of using the referrer, you can implement window.postMessage to communicate accross iframes/windows across domains.
You post to window.parent, and then parent returns the URL.
This works, but it requires asynchronous communication.
You will have to write a synchronous wrapper around the asynchronous methods, if you need it synchronous.

After a lot of research I finally found the ultimate solution. It works even for floated elements. View Source

.element {
    position: relative;
    top: 50%;
    transform: translateY(-50%); /* or try 50% */
}

Or, you could use this:

adb shell am start -n com.package.name/.ActivityName

After activating the virtual environment and installing Flask, I created an app.py file. I run it like this : python -m flask run. Hope this will help!

If you haven't added yourself to the group that owns .git/, then you should.

sudo usermod -a -G $(stat -c '%G' .git) $USER
sudo chmod g+u .git -R
sudo chmod g+u .gitignore
su - $USER

What this does:

1. finds out which group owns .git/ and adds your user to that group.
2. makes sure group members have the same permissions as the owner for .git/.
3. repeats this for .gitignore, which you'll probably need
4. logs you out and back in to refresh your group membership file permissions

If you just recently did something like this (added yourself to the group that owns .git/), then you need to log out and back in before you'll be able to write to .git/FETCH_HEAD during your git pull.

DATEDIFF(minute,startdate,enddate)/60.0)

Or use this for 2 decimal places:

CAST(DATEDIFF(minute,startdate,enddate)/60.0 as decimal(18,2))

Try this command in terminal and then reload. It worked for me

adb reverse tcp:8081 tcp:8081

document.getElementsByClassName('btn-pageMenu') delivers a nodeList. You should use: document.getElementsByClassName('btn-pageMenu')[0].style.display (if it's the first element from that list you want to change.

If you want to change style.display for all nodes loop through the list:

var elems = document.getElementsByClassName('btn-pageMenu');
for (var i=0;i<elems.length;i+=1){
  elems[i].style.display = 'block';
}

to be complete: if you use jquery it is as simple as:

?$('.btn-pageMenu').css('display'???????????????????????????,'block');??????

We can also use col-md-offset like this, it would save us from an extra divs code. So instead of three divs we can do by using only one div:

<div class="col-md-4 col-md-offset-4">Centered content</div>

I had the same problem. Even after updating the password using sudo passwd it was not working. I had to give "multiple" roles for my user through IAM & Admin Refer Screen Shot on IAM & Admin screen of google cloud

You cannot access elements of an empty vector by subscript.
Always check that the vector is not empty & the index is valid while using the [] operator on std::vector.
[] does not add elements if none exists, but it causes an Undefined Behavior if the index is invalid.

You should create a temporary object of your structure, fill it up and then add it to the vector, using vector::push_back()

subject subObj;
subObj.name = s1;
sub.push_back(subObj);

You could just use ArrayList which does the job for you.

There are three options, that you can use. -I is to exclude binary files in grep. Other are for line numbers and file names.

grep -I -n -H 


-I -- process a binary file as if it did not contain matching data; 
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match

So this might be a way to run grep:

grep -InH your-word *

Execute chmod 777 -R scripts/, it worked fine for me ;)

First, make sure you initialize it in document.ready like this:

$(document).ready(function () {
    $('select').material_select();
});

Then, populate it with your data in the way you want. My example:

    function FillMySelect(myCustomData) {
       $("#mySelect").html('');

        $.each(myCustomData, function (key, value) {
           $("#mySelect").append("<option value='" + value.id+ "'>" + value.name + "</option>");
        });
}

Make sure after you are done with the population, to trigger this contentChanged like this:

$("#mySelect").trigger('contentChanged');

EOF indicates "end of file". A newline (which is what happens when you press enter) isn't the end of a file, it's the end of a line, so a newline doesn't terminate this loop.

The code isn't wrong[*], it just doesn't do what you seem to expect. It reads to the end of the input, but you seem to want to read only to the end of a line.

The value of EOF is -1 because it has to be different from any return value from getchar that is an actual character. So getchar returns any character value as an unsigned char, converted to int, which will therefore be non-negative.

If you're typing at the terminal and you want to provoke an end-of-file, use CTRL-D (unix-style systems) or CTRL-Z (Windows). Then after all the input has been read, getchar() will return EOF, and hence getchar() != EOF will be false, and the loop will terminate.

[*] well, it has undefined behavior if the input is more than LONG_MAX characters due to integer overflow, but we can probably forgive that in a simple example.

I solved my problem like this

$('#startdatetime-from').datetimepicker({
language: 'en',
format: 'yyyy-MM-dd hh:mm',
defaultDate:new Date()
});

i'd just do a simple check to see if d[a] exists and if not initialize it...

var a = "1",
    b = "hello",
    c = { "100" : "some important data" },
    d = {};

    if (d[a] === undefined) {
        d[a] = {}
    };
    d[a]["greeting"] = b;
    d[a]["data"] = c;

    console.debug (d);

For List<List<List<x>>> and so on, use

list.SelectMany(x => x.SelectMany(y => y)).ToList();

This has been posted in a comment, but it does deserves a separate reply in my opinion.

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.

So register the ChildComponent in Shared Module manually.

The schema definition for an attribute determines whether an attribute must have a value. If the manager attribute in the example given is the attribute defined in RFC4524 with OID 0.9.2342.19200300.100.1.10, then that attribute has DN syntax. DN syntax is a sequence of relative distinguished names and must not be empty. The filter given in the example is used to cause the LDAP directory server to return only entries that do not have a manager attribute to the LDAP client in the search result.

Use serialize() on the variable, then save the string to a file. later you will be able to read the serialed var from the file and rebuilt the original var (wether it was a string or an array or an object)

There is also an option to make configuration static in startup.cs so that what you can access it anywhere with ease, static variables are convenient huh!

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

internal static IConfiguration Configuration { get; private set; }

This makes configuration accessible anywhere using Startup.Configuration.GetSection... What can go wrong?

I was trying to access my web pages on specific port number and tried much things, but I've found the port was filtered by firewall. Just added a bypass rule and everything was done.

Maybe help someone!

Just to add another flavor from the Reuben response, I use it like this to add or remove this rule according to a condition:

    RelativeLayout.LayoutParams layoutParams =
            (RelativeLayout.LayoutParams) holder.txtGuestName.getLayoutParams();

    if (SOMETHING_THAT_WOULD_LIKE_YOU_TO_CHECK) {
        // if true center text:
        layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
        holder.txtGuestName.setLayoutParams(layoutParams);
    } else {
        // if false remove center:
        layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, 0);
        holder.txtGuestName.setLayoutParams(layoutParams);
    }

I use sql-workbench for working with H2 and any other DBMS I have to deal with and it makes me smile :-)

IF you know the width of the container, you could do like this:

#container
  width: #{200}px
  #element
    width: #{(0.25 * 200) - 5}px

I'm aware that in many cases #container could have a relative width. Then this wouldn't work.

in your css :

 #txtComputer {
      font-size: 24px;
 }

You can style an input entirely (background, color, etc.) and even use the hover event.

If you are trying to convert all string to lowercase in the list, You can use pandas :

import pandas as pd

data = ['Study', 'Insights']

pd_d = list(pd.Series(data).str.lower())

output:

['study', 'insights']

Got it working! I should have been building a JSONArray of JSONObjects and then add the array to a final "Addresses" JSONObject. Observe the following:

JSONObject json      = new JSONObject();
JSONArray  addresses = new JSONArray();
JSONObject address;
try
{
   int count = 15;

   for (int i=0 ; i<count ; i++)
   {
       address = new JSONObject();
       address.put("CustomerName"     , "Decepticons" + i);
       address.put("AccountId"        , "1999" + i);
       address.put("SiteId"           , "1888" + i);
       address.put("Number"            , "7" + i);
       address.put("Building"          , "StarScream Skyscraper" + i);
       address.put("Street"            , "Devestator Avenue" + i);
       address.put("City"              , "Megatron City" + i);
       address.put("ZipCode"          , "ZZ00 XX1" + i);
       address.put("Country"           , "CyberTron" + i);
       addresses.add(address);
   }
   json.put("Addresses", addresses);
}
catch (JSONException jse)
{ 

}
response.setContentType("application/json");
response.getWriter().write(json.toString());

This worked and returned valid and parse-able JSON. Hopefully this helps someone else in the future. Thanks for your help Marcel

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

Very basic example with $lookup.

db.getCollection('users').aggregate([
    {
        $lookup: {
            from: "userinfo",
            localField: "userId",
            foreignField: "userId",
            as: "userInfoData"
        }
    },
    {
        $lookup: {
            from: "userrole",
            localField: "userId",
            foreignField: "userId",
            as: "userRoleData"
        }
    },
    { $unwind: { path: "$userInfoData", preserveNullAndEmptyArrays: true }},
    { $unwind: { path: "$userRoleData", preserveNullAndEmptyArrays: true }}
])

Here is used

 { $unwind: { path: "$userInfoData", preserveNullAndEmptyArrays: true }}, 
 { $unwind: { path: "$userRoleData", preserveNullAndEmptyArrays: true }}

Instead of

{ $unwind:"$userRoleData"} 
{ $unwind:"$userRoleData"}

Because { $unwind:"$userRoleData"} this will return empty or 0 result if no matching record found with $lookup.

put following code in your page

  Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequest);
    function EndRequest(sender, args) {
        if (args.get_error() == undefined) {
        $('.dropdown-toggle').dropdown();
        }
    }

This regex works well for me to validate password:

/[ !"#$%&'()*+,-./:;<=>?@[\\\]^_`{|}~]/

This list of special characters (including white space and punctuation) was taken from here: https://www.owasp.org/index.php/Password_special_characters. It was changed a bit, cause backslash ('\') and closing bracket (']') had to be escaped for proper work of the regex. That's why two additional backslash characters were added.

The short and sweet version:

• ($) calls the function which is its left-hand argument on the value which is its right-hand argument.
• (.) composes the function which is its left-hand argument on the function which is its right-hand argument.

You'll get converting errors with:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

Use instead:

string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
    found = true; 
} else {
    found = false; 
}

Because you are passing a string as the second argument to the date function, which should be an integer.

string date ( string $format [, int $timestamp = time() ] )

Try strtotime which will Parse about any English textual datetime description into a Unix timestamp (integer):

date("d", strtotime($_GET['start_date']));

Two steps:

• Generate the log
• Load Gmail to send the log

.

1. Generate the log

   File generateLog() {
       File logFolder = new File(Environment.getExternalStorageDirectory(), "MyFolder");
       if (!logFolder.exists()) {
           logFolder.mkdir();
       }
       String filename = "myapp_log_" + new Date().getTime() + ".log";
   
       File logFile = new File(logFolder, filename);
   
       try {
           String[] cmd = new String[] { "logcat", "-f", logFile.getAbsolutePath(), "-v", "time", "ActivityManager:W", "myapp:D" };
           Runtime.getRuntime().exec(cmd);
           Toaster.shortDebug("Log generated to: " + filename);
           return logFile;
       }
       catch (IOException ioEx) {
           ioEx.printStackTrace();
       }
   
       return null;
   }
   

2. Load Gmail to send the log

   File logFile = generateLog();
   Intent intent = new Intent(Intent.ACTION_SEND);
   intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(logFile));
   intent.setType("multipart/");
   startActivity(intent);

For #2 - there are many different answers out there for how to load the log file to view and send. Finally, the solution here actually worked to both:

• load Gmail as an option
• attaches the file successfully

Big thanks to https://stackoverflow.com/a/22367055/2162226 for the correctly working answer

unsupported-major-minor-version error can be because of unsupported JDK version. Update JDK, Go to Module Settings and change the JDK path to the new one. In most of the cases, it fixes the error.

The collection.count is deprecated, and will be removed in a future version. Use collection.countDocuments or collection.estimatedDocumentCount instead.

userModel.countDocuments(query).exec((err, count) => {
    if (err) {
        res.send(err);
        return;
    }

    res.json({ count: count });
});

Found the answer in How to lay out Views in RelativeLayout programmatically?

We should explicitly set id's using setId(). Only then, RIGHT_OF rules make sense.

Another mistake I did is, reusing the layoutparams object between the controls. We should create new object for each control

I had similar expirience like yours. I have Denwer server. When I loaded my http://new.new local site without using via script src jquery.min.js file at index.php in Chrome I got error 500 jquery.min.map in console. I resolved this problem simply - I disabled extension Wunderlist in Chrome and voila - I never see this error more. Although, No, I found this error again - when Wunderlist have been on again. So, check your extensions and try to disable all of them or some of them or one by one. Good luck!

You can have both formats as an argument to the function date():

date("d-m-Y H:i:s")

Check the manual for more info : http://php.net/manual/en/function.date.php

As pointed out by @ThomasVdBerge to display minutes you need the 'i' character

The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.

What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!

I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.

So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:

import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;

//  create and initialize an object 
public static JSONObject buildObject( final SimpleEntry... entries ) { 
    JSONObject object = new JSONObject();
    for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
    return object;
}

//  nest a list of objects inside another                          
public static void putObjects( final JSONObject parentObject, final String key,
                               final JSONObject... objects ) { 
    List objectList = new ArrayList<JSONObject>();
    for( JSONObject o : objects ) objectList.add( o );
    parentObject.put( key, objectList );
}   

Implementation example:

JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
    buildObject( 
        new SimpleEntry( "child1Key1", "someValue" )
      , new SimpleEntry( "child1Key2", "someValue" ) 
    )
  , buildObject( 
        new SimpleEntry( "child2Key1", "someValue" )
      , new SimpleEntry( "child2Key2", "someValue" ) 
    )
);      

You can use attached properties for setting button border radius (also the same will work for textboxes).

Create class for attached property

public class CornerRadiusSetter
{
    public static CornerRadius GetCornerRadius(DependencyObject obj) => (CornerRadius)obj.GetValue(CornerRadiusProperty);

    public static void SetCornerRadius(DependencyObject obj, CornerRadius value) => obj.SetValue(CornerRadiusProperty, value);

    public static readonly DependencyProperty CornerRadiusProperty =
        DependencyProperty.RegisterAttached(nameof(Border.CornerRadius), typeof(CornerRadius),
            typeof(CornerRadiusSetter), new UIPropertyMetadata(new CornerRadius(), CornerRadiusChangedCallback));

    public static void CornerRadiusChangedCallback(object sender, DependencyPropertyChangedEventArgs e)
    {
        Control control = sender as Control;

        if (control == null) return;

        control.Loaded -= Control_Loaded;
        control.Loaded += Control_Loaded;
    }

    private static void Control_Loaded(object sender, EventArgs e)
    {
        Control control = sender as Control;

        if (control == null || control.Template == null) return;

        control.ApplyTemplate();

        Border border = control.Template.FindName("border", control) as Border;

        if (border == null) return;

        border.CornerRadius = GetCornerRadius(control);
    }
}

Then you can use attached property syntax for multiple buttons without style duplicates:

<Button local:CornerRadiusSetter.CornerRadius="10">Click me!</Button>
<Button local:CornerRadiusSetter.CornerRadius="5, 0, 0, 5">Click me!</Button>
<Button local:CornerRadiusSetter.CornerRadius="3, 20, 8, 15">Click me!</Button>

That's because you have selected your Master table on the table drop down Table Selected

Select the table you want to use and proceed executing your query

This answer is specific to x86. Portable tools that can disassemble AArch64, MIPS, or whatever machine code include objdump and llvm-objdump.

Agner Fog's disassembler, objconv, is quite nice. It will add comments to the disassembly output for performance problems (like the dreaded LCP stall from instructions with 16bit immediate constants, for example).

objconv  -fyasm a.out /dev/stdout | less

(It doesn't recognize - as shorthand for stdout, and defaults to outputting to a file of similar name to the input file, with .asm tacked on.)

It also adds branch targets to the code. Other disassemblers usually disassemble jump instructions with just a numeric destination, and don't put any marker at a branch target to help you find the top of loops and so on.

It also indicates NOPs more clearly than other disassemblers (making it clear when there's padding, rather than disassembling it as just another instruction.)

It's open source, and easy to compile for Linux. It can disassemble into NASM, YASM, MASM, or GNU (AT&T) syntax.

Note that this output is ready to be assembled back into an object file, so you can tweak the code at the asm source level, rather than with a hex-editor on the machine code. (So you aren't limited to keeping things the same size.) With no changes, the result should be near-identical. It might not be, though, since disassembly of stuff like

doesn't have anything in the source to make sure it assembles to the longer encoding that leaves room for relocations to rewrite it with a 32bit offset.

If you don't want to install it objconv, GNU binutils objdump -Mintel -d is very usable, and will already be installed if you have a normal Linux gcc setup.

I have also used the eclipse plugin to get the project into the eclipse workspace. Since I've worked on a different project I saw that it is possible to work with eclipse but without the maven-eclipse-plugin. That makes it easier to use with different environments and enables the easy use of maven over eclipse. And that without changing the pom.xml-file.

So, I recommend the approach of Gabriel Ramirez.

increase the response.getBufferSize() get the buffer size and compare with the bytes you want to transfer !

I agree with above answers, Here is a complete read and write sample for anyone who needs it.

     router.post('/', function(req, res, next) {

        console.log(req.body);
        var id = Math.floor((Math.random()*100)+1);

        var tital = req.body.title;
        var description = req.body.description;
        var mynotes = {"Id": id, "Title":tital, "Description": description};
        
        fs.readFile('db.json','utf8', function(err,data){
            var obj = JSON.parse(data);
            obj.push(mynotes);
            var strNotes = JSON.stringify(obj);
            fs.writeFile('db.json',strNotes, function(err){
                if(err) return console.log(err);
                console.log('Note added');
            });

        })
        
        
    });


  

Put the loops in a subroutine and call return

The != operator serves this purpose for bool values.

onClick you should call function, thats called your function toggle.

onClick={() => this.toggle()}

Your method needs to return a ActionResult type:

public ActionResult Index()
{
    //All we want to do is redirect to the class selection page
    return RedirectToAction("SelectClasses", "Registration");

You have an extra -c you need to get rid of:

psexec -u administrator -p force \\135.20.230.160 -s -d cmd.exe /c "C:\Amitra\bogus.bat"

You can use display:inline-block.

This property allows a DOM element to have all the attributes of a block element, but keeping it inline. There's some drawbacks, but most of the time it's good enough. Why it's good and why it may not work for you.

EDIT: The only modern browser that has some problems with it is IE7. See Quirksmode.org

Here's how I did it:

A = ['a','b','c']
B = ['c']
logic = [(x in B) for x in A]
if True in logic:
    do something

It is dramatically more efficient to use IndexedOrderedDict from the indexed package.

Following Niklas's comment, I have done a benchmark on OrderedDict and IndexedOrderedDict with 1000 entries.

In [1]: from numpy import *
In [2]: from indexed import IndexedOrderedDict
In [3]: id=IndexedOrderedDict(zip(arange(1000),random.random(1000)))
In [4]: timeit id.keys()[56]
1000000 loops, best of 3: 969 ns per loop

In [8]: from collections import OrderedDict
In [9]: od=OrderedDict(zip(arange(1000),random.random(1000)))
In [10]: timeit od.keys()[56]
10000 loops, best of 3: 104 µs per loop

IndexedOrderedDict is ~100 times faster in indexing elements at specific position in this specific case.

Another solution possible to this error is check your Java version, maybe you can solve it downloading this jdk oracle-jdk-8, this was my mistake :P

Here's a webkit example which works for Chrome and Safari:

CSS:

::-webkit-scrollbar 
{
    width: 40px;
    background-color:#4F4F4F;
}

::-webkit-scrollbar-button:vertical:increment 
{
    height:40px;
    background-image: url(/Images/Scrollbar/decrement.png);
    background-size:39px 30px;
    background-repeat:no-repeat;
}

::-webkit-scrollbar-button:vertical:decrement 
{
    height:40px;
    background-image: url(/Images/Scrollbar/increment.png);    
    background-size:39px 30px;
    background-repeat:no-repeat;
}

Output:

for example try this :

<a href="http://www.google.com" id="myLink1">open link 1</a><br/> <a href="http://www.youtube.com" id="myLink2">open link 2</a>

    document.getElementById("myLink1").onclick = function() {
    window.open(
    "http://www.facebook.com"
        );
        return false;
      };

      document.getElementById("myLink2").onclick = function() {
    window.open(
    "http://www.yahoo.com"
        );
        return false;
      };

1) You can use the !important rule, like this:

.selected
{
  background-color:red !important;
}

See http://www.w3.org/TR/CSS2/cascade.html#important-rules for more info.

2) In your example you can also get the red background by using ul.nav li.selected instead of just .selected. This makes the selector more specific.

See http://www.w3.org/TR/CSS2/cascade.html#specificity for more info.

Alternatively you can use the following methods in JunitCore class http://junit.sourceforge.net/javadoc/org/junit/runner/JUnitCore.html

run (with Request , Class classes and Runner) or runClasses from your java file.
