Ack! Constant strings:

const char *strings[] = {"one","two","three"};

If I remember correctly.

Oh, and you want to use strcpy for assignment, not the = operator. strcpy_s is safer, but it's neither in C89 nor in C99 standards.

char arr[MAX_NUMBER_STRINGS][MAX_STRING_SIZE]; 
strcpy(arr[0], "blah");

Update: Thomas says strlcpy is the way to go.

Use document.location.href to change the page location, place it in the function on a successful ajax run.

train_test_split is part of the module sklearn.model_selection, hence, you may need to import the module from model_selection

Code:

from sklearn.model_selection import train_test_split

It's way better than Resharper (which by the way always slowed down my VS to a crawl), it works with C# and VB.NET (including refactoring) and the support and community is excellent. Worth the price tag. And yes, it does support 2010 (in RC at the time of this writing).

It's not clear how you want your Date logic to behave? Usually a good way to deal with default behaviour is the Null Object pattern.

I use the following:

UIView *view = [[UIView alloc] init];
myTableView.tableFooterView = view;
[view release];

Doing it in viewDidLoad. But you can set it anywhere.

Rhomobile Rhodes (http://rhomobile.com/products/rhodes) is very similar in approach to PhoneGap, but is the only framework with:

1. a Model View Controller pattern (as most web frameworks provide)
2. an Object Relational Manager
3. support for all popular smartphones (including Windows Phone 7)
4. a hosted development service (not just hosted build): http://rhohub.com
5. a full debugger and SDK-less emulator in the RhoStudio IDE
6. support for synchronized offline data

You have two options:

1. Define a named class. Pass your parameter to the constructor of the named class.

2. Have your anonymous class close over your "parameter". Be sure to mark it as final.

Easiest way is probably

pip3 -V

This will show you where your pip is installed and therefore where your packages are located.

If you need to use a function to cast:

var list1 = new List<Type1>();
var list2 = new List<Type2>();

list2 = list1.ConvertAll(x => myConvertFuntion(x));

Where my custom function is:

private Type2 myConvertFunction(Type1 obj){
   //do something to cast Type1 into Type2
   return new Type2();
}

If you came across this error while using the command line its because you must be using php 7 to execute whatever it is you are trying to execute. What happened is that the code is trying to use an operator thats only available in php7+ and is causing a syntax error.

If you already have php 7+ on your computer try pointing the command line to the higher version of php you want to use.

export PATH=/usr/local/[php-7-folder]/bin/:$PATH

Here is the exact location that worked based off of my setup for reference:

export PATH=/usr/local/php5-7.1.4-20170506-100436/bin/:$PATH

The operator thats actually caused the break is the "null coalesce operator" you can read more about it here:

Okay, so I've joined the google group of libphonenumber ( https://groups.google.com/forum/?hl=en&fromgroups#!forum/libphonenumber-discuss ) and I've asked a question.

I don't need to set the country in parameter if my phone number begins with "+". Here is an example :

PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    // phone must begin with '+'
    PhoneNumber numberProto = phoneUtil.parse(phone, "");
    int countryCode = numberProto.getCountryCode();
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

This might be a better approach than top answer if you need to compare 2 output arrays to each other but use the first array to populate the options.

This is also helpful when you have a non-numeric or offset index (key) in your array.

<select name="roles[]" multiple>
    @foreach($roles as $key => $value)
        <option value="{{$key}}" @if(in_array($value, $compare_roles))selected="selected"@endif>
            {{$value}}
        </option>
    @endforeach
</select>

In 2020, I use apply() with argument result_type='expand'

>>> appiled_df = df.apply(lambda row: fn(row.text), axis='columns', result_type='expand')
>>> df = pd.concat([df, appiled_df], axis='columns')

Use the DO statement, a new option in version 9.0:

DO LANGUAGE plpgsql
$$
BEGIN
CREATE TABLE "Logs"."Events"
    (
        EventId BIGSERIAL NOT NULL PRIMARY KEY,
        PrimaryKeyId bigint NOT NULL,
        EventDateTime date NOT NULL DEFAULT(now()),
        Action varchar(12) NOT NULL,
        UserId integer NOT NULL REFERENCES "Office"."Users"(UserId),
        PrincipalUserId varchar(50) NOT NULL DEFAULT(user)
    );

    CREATE TABLE "Logs"."EventDetails"
    (
        EventDetailId BIGSERIAL NOT NULL PRIMARY KEY,
        EventId bigint NOT NULL REFERENCES "Logs"."Events"(EventId),

In my case I was using Windows 7 with the 64-bit OS. We installed the 64-bit Java SE and 64-bit ADT Bundle. With that set up, we couldn't get the SDK manager to work correctly (specifically, no downloads allowed and it didn't show all the API download options). After trying all of the above answers and from other posts, we decided to look into the Java set up and realized it might the 64-bit configuration that's giving the ADT bundle grief (I vaguely recall seeing/reading this issue before).

So we uninstalled Java 64-bit and reinstalled the 32-bit, and then used the 32-bit ADT bundle, and it worked correctly. The system user was already an admin, so we didn't need to "Run as Administrator"

You can add "_CRT_SECURE_NO_WARNINGS" in Preprocessor Definitions.

Right-click your project->Properties->Configuration Properties->C/C++ ->Preprocessor->Preprocessor Definitions.

If you need to update user information for a specific user ID "x",

1. you need to create a dbManager class that will initialise the database in its constructor and acts as a mediator between your viewModel and DAO, and also .

2. The ViewModel will initialize an instance of dbManager to access the database. The code should look like this:

      @Entity
       class User{
       @PrimaryKey
       String userId;
       String username;
       }
   
       Interface UserDao{
       //forUpdate
       @Update
       void updateUser(User user)
       }
   
       Class DbManager{
       //AppDatabase gets the static object o roomDatabase.
       AppDatabase appDatabase;
       UserDao userDao;
       public DbManager(Application application ){
       appDatabase = AppDatabase.getInstance(application);
   
       //getUserDao is and abstract method of type UserDao declared in AppDatabase //class
       userDao = appDatabase.getUserDao();
       } 
   
       public void updateUser(User user, boolean isUpdate){
       new InsertUpdateUserAsyncTask(userDao,isUpdate).execute(user);
       }
   
   
   
       public static class InsertUpdateUserAsyncTask extends AsyncTask<User, Void, Void> {
   
   
        private UserDao userDAO;
        private boolean isInsert;
   
        public InsertUpdateBrandAsyncTask(BrandDAO userDAO, boolean isInsert) {
          this. userDAO = userDAO;
          this.isInsert = isInsert;
        }
   
        @Override
        protected Void doInBackground(User... users) {
          if (isInsert)
       userDAO.insertBrand(brandEntities[0]);
          else
       //for update
       userDAO.updateBrand(users[0]);
       //try {
       //  Thread.sleep(1000);
       //} catch (InterruptedException e) {
       //  e.printStackTrace();
       //}
          return null;
        }
         }
       }
   
        Class UserViewModel{
        DbManager dbManager;
        public UserViewModel(Application application){
        dbmanager = new DbMnager(application);
        }
   
        public void updateUser(User user, boolean isUpdate){
        dbmanager.updateUser(user,isUpdate);
        }
   
        }
   
   
   
   
   Now in your activity or fragment initialise your UserViewModel like this:
   
   UserViewModel userViewModel = ViewModelProviders.of(this).get(UserViewModel.class);
   

   Then just update your user item this way, suppose your userId is 1122 and userName is "xyz" which has to be changed to "zyx".

   Get an userItem of id 1122 User object

User user = new user();
 if(user.getUserId() == 1122){
   user.setuserName("zyx");
   userViewModel.updateUser(user);
 }

This is a raw code, hope it helps you.

Happy coding

If you use an = statement to assign a value to a var with an object on the right side, javascript will not copy but reference the object.

You can use lodash's clone method

var obj = {a: 25, b: 50, c: 75};
var A = _.clone(obj);

Or lodash's cloneDeep method if your object has multiple object levels

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.cloneDeep(obj);

Or lodash's merge method if you mean to extend the source object

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.merge({}, obj, {newkey: "newvalue"});

Or you can use jQuerys extend method:

var obj = {a: 25, b: 50, c: 75};
var A = $.extend(true,{},obj);

Here is jQuery 1.11 extend method's source code :

jQuery.extend = jQuery.fn.extend = function() {
    var src, copyIsArray, copy, name, options, clone,
        target = arguments[0] || {},
        i = 1,
        length = arguments.length,
        deep = false;

    // Handle a deep copy situation
    if ( typeof target === "boolean" ) {
        deep = target;

        // skip the boolean and the target
        target = arguments[ i ] || {};
        i++;
    }

    // Handle case when target is a string or something (possible in deep copy)
    if ( typeof target !== "object" && !jQuery.isFunction(target) ) {
        target = {};
    }

    // extend jQuery itself if only one argument is passed
    if ( i === length ) {
        target = this;
        i--;
    }

    for ( ; i < length; i++ ) {
        // Only deal with non-null/undefined values
        if ( (options = arguments[ i ]) != null ) {
            // Extend the base object
            for ( name in options ) {
                src = target[ name ];
                copy = options[ name ];

                // Prevent never-ending loop
                if ( target === copy ) {
                    continue;
                }

                // Recurse if we're merging plain objects or arrays
                if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) ) ) {
                    if ( copyIsArray ) {
                        copyIsArray = false;
                        clone = src && jQuery.isArray(src) ? src : [];

                    } else {
                        clone = src && jQuery.isPlainObject(src) ? src : {};
                    }

                    // Never move original objects, clone them
                    target[ name ] = jQuery.extend( deep, clone, copy );

                // Don't bring in undefined values
                } else if ( copy !== undefined ) {
                    target[ name ] = copy;
                }
            }
        }
    }

    // Return the modified object
    return target;
};

At least for me, the signal(SIGSEGV ...) approach mentioned in another answer did not work on Win32 with Visual C++ 2015. What did work for me was to use _set_se_translator() found in eh.h. It works like this:

Step 1) Make sure you enable Yes with SEH Exceptions (/EHa) in Project Properties / C++ / Code Generation / Enable C++ Exceptions, as mentioned in the answer by Volodymyr Frytskyy.

Step 2) Call _set_se_translator(), passing in a function pointer (or lambda) for the new exception translator. It is called a translator because it basically just takes the low-level exception and re-throws it as something easier to catch, such as std::exception:

#include <string>
#include <eh.h>

// Be sure to enable "Yes with SEH Exceptions (/EHa)" in C++ / Code Generation;
_set_se_translator([](unsigned int u, EXCEPTION_POINTERS *pExp) {
    std::string error = "SE Exception: ";
    switch (u) {
    case 0xC0000005:
        error += "Access Violation";
        break;
    default:
        char result[11];
        sprintf_s(result, 11, "0x%08X", u);
        error += result;
    };
    throw std::exception(error.c_str());
});

Step 3) Catch the exception like you normally would:

try{
    MakeAnException();
}
catch(std::exception ex){
    HandleIt();
};

yes it's possible to print a string to the console.

#include "stdafx.h"
#include <string>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    string strMytestString("hello world");
    cout << strMytestString;
    return 0;
}

stdafx.h isn't pertinent to the solution, everything else is.

If a method only accesses local variables, it's thread safe. Is that it?

Absolultely not. You can write a program with only a single local variable accessed from a single thread that is nevertheless not threadsafe:

https://stackoverflow.com/a/8883117/88656

Does that apply for static methods as well?

Absolutely not.

One answer, provided by @Cybis, was: "Local variables cannot be shared among threads because each thread gets its own stack."

Absolutely not. The distinguishing characteristic of a local variable is that it is only visible from within the local scope, not that it is allocated on the temporary pool. It is perfectly legal and possible to access the same local variable from two different threads. You can do so by using anonymous methods, lambdas, iterator blocks or async methods.

Is that the case for static methods as well?

Absolutely not.

If a method is passed a reference object, does that break thread safety?

Maybe.

I've done some research, and there is a lot out there about certain cases, but I was hoping to be able to define, by using just a few rules, guidelines to follow to make sure a method is thread safe.

You are going to have to learn to live with disappointment. This is a very difficult subject.

So, I guess my ultimate question is: "Is there a short list of rules that define a thread-safe method?

Nope. As you saw from my example earlier an empty method can be non-thread-safe. You might as well ask "is there a short list of rules that ensures a method is correct". No, there is not. Thread safety is nothing more than an extremely complicated kind of correctness.

Moreover, the fact that you are asking the question indicates your fundamental misunderstanding about thread safety. Thread safety is a global, not a local property of a program. The reason why it is so hard to get right is because you must have a complete knowledge of the threading behaviour of the entire program in order to ensure its safety.

Again, look at my example: every method is trivial. It is the way that the methods interact with each other at a "global" level that makes the program deadlock. You can't look at every method and check it off as "safe" and then expect that the whole program is safe, any more than you can conclude that because your house is made of 100% non-hollow bricks that the house is also non-hollow. The hollowness of a house is a global property of the whole thing, not an aggregate of the properties of its parts.

From access help:

Stop Disabled Mode from blocking a query If you try to run an append query and it seems like nothing happens, check the Access status bar for the following message:

This action or event has been blocked by Disabled Mode.

To stop Disabled Mode from blocking the query, you must enable the database content. You use the Options button in the Message Bar to enable the query.

Enable the append query In the Message Bar, click Options. In the Microsoft Office Security Options dialog box, click Enable this content, and then click OK. If you don't see the Message Bar, it may be hidden. You can show it, unless it has also been disabled. If the Message Bar has been disabled, you can enable it.

Show the Message Bar If the Message Bar is already visible, you can skip this step.

On the Database Tools tab, in the Show/Hide group, select the Message Bar check box. If the Message Bar check box is disabled, you will have to enable it.

Enable the Message Bar If the Message Bar check box is enabled, you can skip this step.

Click the Microsoft Office Button , and then click Access Options. In the left pane of the Access Options dialog box, click Trust Center. In the right pane, under Microsoft Office Access Trust Center, click Trust Center Settings. In the left pane of the Trust Center dialog box, click Message Bar. In the right pane, click Show the Message Bar in all applications when content has been blocked, and then click OK. Close and reopen the database to apply the changed setting. Note When you enable the append query, you also enable all other database content.

It is similar to some of the other aproaches here. Hope helps :)

Based on your question, I think that you may be a bit confused about the difference between a User and a Login. A Login is an account on the SQL Server as a whole - someone who is able to log in to the server and who has a password. A User is a Login with access to a specific database.

Creating a Login is easy and must (obviously) be done before creating a User account for the login in a specific database:

CREATE LOGIN NewAdminName WITH PASSWORD = 'ABCD'
GO

Here is how you create a User with db_owner privileges using the Login you just declared:

Use YourDatabase;
GO

IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'NewAdminName')
BEGIN
    CREATE USER [NewAdminName] FOR LOGIN [NewAdminName]
    EXEC sp_addrolemember N'db_owner', N'NewAdminName'
END;
GO

Now, Logins are a bit more fluid than I make it seem above. For example, a Login account is automatically created (in most SQL Server installations) for the Windows Administrator account when the database is installed. In most situations, I just use that when I am administering a database (it has all privileges).

However, if you are going to be accessing the SQL Server from an application, then you will want to set the server up for "Mixed Mode" (both Windows and SQL logins) and create a Login as shown above. You'll then "GRANT" priviliges to that SQL Login based on what is needed for your app. See here for more information.

UPDATE: Aaron points out the use of the sp_addsrvrolemember to assign a prepared role to your login account. This is a good idea - faster and easier than manually granting privileges. If you google it you'll see plenty of links. However, you must still understand the distinction between a login and a user.

This works for me:

function isTouchDevice(){
    return true == ("ontouchstart" in window || window.DocumentTouch && document instanceof DocumentTouch);
}

The MultiByteToWideChar answer that Charles Bailey gave is the correct one. Because LPCWSTR is just a typedef for const WCHAR*, widestr in the example code there can be used wherever a LPWSTR is expected or where a LPCWSTR is expected.

One minor tweak would be to use std::vector<WCHAR> instead of a manually managed array:

// using vector, buffer is deallocated when function ends
std::vector<WCHAR> widestr(bufferlen + 1);

::MultiByteToWideChar(CP_ACP, 0, instr.c_str(), instr.size(), &widestr[0], bufferlen);

// Ensure wide string is null terminated
widestr[bufferlen] = 0;

// no need to delete; handled by vector

Also, if you need to work with wide strings to start with, you can use std::wstring instead of std::string. If you want to work with the Windows TCHAR type, you can use std::basic_string<TCHAR>. Converting from std::wstring to LPCWSTR or from std::basic_string<TCHAR> to LPCTSTR is just a matter of calling c_str. It's when you're changing between ANSI and UTF-16 characters that MultiByteToWideChar (and its inverse WideCharToMultiByte) comes into the picture.

In VS2013 F4 on your project to view properties window and disable Anonymous access and enable "Windows authentication"

Then it will work. No need to change anything else

If loading images dynamically one can create a .js file like following and do require in it.

export const data = [
  {
    id: "1",
    text: "blablabla1",
    imageLink: require('../assets/first-image.png')
  },
  {
    id: "2",
    text: "blablabla2",
    imageLink: require('../assets/second-image.png')
  }
]

In your component .js file

import {data} from './js-u-created-above';
...

function UsageExample({item}) {
   <View>
     <Image style={...} source={item.imageLink} /> 
   </View>
}

function ComponentName() {
   const elements = data.map(item => <UsageExample key={item.id} item={item}/> );
   return (...);
}

You have a couple of options:

1. Scope the domain down (see document.domain) in both the containing page and the iframe to the same thing. Then they will not be bound by 'same origin' constraints.

2. Use postMessage which is supported by all HTML5 browsers for cross-domain communication.

Assuming you want a default button checked.

<div class="row">
    <h1>Radio Group #2</h1>
    <label for="year" class="control-label input-group">Year</label>
    <div class="btn-group" data-toggle="buttons">
        <label class="btn btn-default">
            <input type="radio" name="year" value="2011">2011
        </label>
        <label class="btn btn-default">
            <input type="radio" name="year" value="2012">2012
        </label>
        <label class="btn btn-default active">
            <input type="radio" name="year" value="2013" checked="">2013
        </label>
    </div>
  </div>

Add the active class to the button (label tag) you want defaulted and checked="" to its input tag so it gets submitted in the form by default.

You can also use a visual diff.

For example, if you are using Sourcetree, you can simply select any two commits in log view.

(I personally prefer using a GUI in most cases for this, and I'm posting this for those who may not be familiar with GUI options.)

With sdk, you can't write to the root of internal storage. This cause your error.

Edit :

Based on your code, to use internal storage with sdk:

final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");

In the Windows Powershell console, type

[System.IO.Directory]::GetFiles("\\.\\pipe\\")

get-childitem \\.\pipe\

This returns a list of objects. If you want the name only:

(get-childitem \\.\pipe\).FullName

(The second example \\.\pipe\ does not work in Powershell 7, but the first example does)

I got here searching for a way to execute some code whenever the program ends.
Found this:

Kernel.at_exit { puts "sayonara" }
# do whatever
# [...]
# call #exit or #abort or just let the program end
# calling #exit! will skip the call

Called multiple times will register multiple handlers.

This is a combination of the above, because I had to read several posts to understand.

1. In the Headers, add the following key-values:
   1. Content-Type to application/json
   2. and Accept to application/json

2. In the Body:
   1. change the type to "raw"
   2. confirm "JSON (application/json)" is the text type
   3. put the nested property there: { "Obj1" : { "key1" : "val1" } }

I had the same error. Weird thing was, I had one new project form scratch, there it worked perfectly and another, much bigger project, where I always ran into that error message.

The perfecrtly working project (nearly) always creates the database (indluding the files) automatically. It can be any command, read, write, update. The files get created. Of course it uses

DropCreateDatabaseIfModelChanges

There is only one case, when it gets troubled: IF the mdf is auto-created and you delete the mdf and log file. Then that was about it. Say good-bye to your autocreation...

The only way I found to fix it was like mentioned:

sqllocaldb stop v11.0 & sqllocaldb delete v11.0

After that, everything is back to normal (and all other Databases handled by LocalDB also gone!).

EDIT: That was not true. I just tried it and the v11.0 gets automatically recreated and all mdfs stay available. I have not tried with "non file based" LocalDBs.

The confusing thing is, I also got this error if something else was wrong. So my suggestion is, if you want to make sure your DB-Setup is sound and solid: Create a new solution/project from scratch, use the most basic DB commands (Add an entity, show all entities, delete all entities) and see if it works.

If YES, the problem is somewhere in the abyss of VS2013 config and versioning and nuget and stuff.

IF NO, you have a problem with your LocalDB installation.

For anyone who really wants to understand what's going on in EF (and I am still not sure if I do :-) ) http://odetocode.com/Blogs/scott/archive/2012/08/14/a-troubleshooting-guide-for-entity-framework-connections-amp-migrations.aspx

P.S.: Nudge me if you need the running example project.

You can try below code in Global.asax file.

protected void Application_BeginRequest()
    {
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
        Response.Cache.SetNoStore();
    }

Add multiple classes:

$("p").addClass("class1 class2 class3");

or in cascade:

$("p").addClass("class1").addClass("class2").addClass("class3");

Very similar also to remove more classes:

$("p").removeClass("class1 class2 class3");

or in cascade:

$("p").removeClass("class1").removeClass("class2").removeClass("class3");

Just add parameters, split by comma:

UPDATE tablename SET column1 = "value1", column2 = "value2" ....

I had a "Install build tools and sync" link in the lower right hand corner of my screen. I clicked on that and it fixed the issue.

Adding to John and Tim's answer.

Unless you are coding for Win98, there are only two of the 6+ string types you should be using in your application

• LPWSTR
• LPCWSTR

The rest are meant to support ANSI platforms or dual compilations. Those are not as relevant today as they used to be.

Add this permission in Manifest,
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

File folder = new File(Environment.getExternalStorageDirectory() + 
                             File.separator + "TollCulator");
boolean success = true;
if (!folder.exists()) {
    success = folder.mkdirs();
}
if (success) {
    // Do something on success
} else {
    // Do something else on failure 
}

when u run the application go too DDMS->File Explorer->mnt folder->sdcard folder->toll-creation folder

OK guys I finally overcame this problem. Here is the solution:

1. Download gradle-1.6-bin.zip for offline use.

2. Paste it in the C:\Users\username\.gradle directory.

3. Open Android Studio and click on the "Create New Project" option and you will not get this error any more while offline.

   You might get some other errors like this:

   

   Don't worry, just ignore it. Your project has been created.

4. So now click on "Import Project" and go to the path C:\Users\username\AndroidStudioProjects and open your project and you are done.

import keyboard

while True:
    print('please say yes')
    if keyboard.is_pressed('y'):
         break
print('i got u :) ')
print('i was trying to write you are a idiot ')
print('  :( ')

for enter use 'ENTER'

If you're trying to write a newline to a file, you could simply use BufferedWriter's newLine() method.

1. No, there isn't anything that should be avoided
2. The parameters related to performance are not in web.xml they are in the servlet container configuration files (server.xml on tomcat)

3. No. But the default servlet (mapped in a web.xml at a common location in your servlet container) should preferably disable file listings (so that users don't see the contents of your web folders):

   listings true

I use intellj idea and in windows in terminal type: gradlew.bat run it is working for me.

A solution is to use the include statement with remote_user var (describe there : http://docs.ansible.com/playbooks_roles.html) but it has to be done at playbook instead of task level.

I would put this as a comment, but I don't have the rep for it. What Josh Crozier answered is correct, but for IE .cur and .ani are the only supported formats for this. So you should probably have a fallback just in case:

.test {
    cursor:url("http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif"), url(foo.cur), auto;
}

Thanks everyone who have answered.I have seen all answers and to try to make it easy for everyone

Step 1: Type edit environment and select the option shown

Step 2: Select Path and click on edit

Step 3: In the end add the below statement(you can avoid the first ; if its already there)

;C:\Program Files\Git\bin\git.exe;C:\Program Files\Git\cmd

Step 4:- Click on ok

Step 5 **:- One of the important step which is highlighted by one of the users. thanks to him. Please, **CLOSE command prompt and REOPEN then try to write git.

**

• Close command prompt and restart before trying the below command

**

Here is the magic

This code sends array of integer values

Initialize array List

List<Integer> test = new ArrayList<Integer>();

Add values to array List

test.add(1);
test.add(2);
test.add(3);
Intent intent=new Intent(this, targetActivty.class);

Send the array list values to target activity

intent.putIntegerArrayListExtra("test", (ArrayList<Integer>) test);
startActivity(intent);

here you get values on targetActivty

Intent intent=getIntent();
ArrayList<String> test = intent.getStringArrayListExtra("test");

Try this in the .htaccess of the external root folder :

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

And if it only concerns .js scripts you should wrap the above code inside this:

<FilesMatch "\.(js)$">
...
</FilesMatch>

You could write a script to update the FK's for you.. check out this blog: http://multunus.com/2011/03/how-to-easily-merge-two-identical-mysql-databases/

They have a clever script to use the information_schema tables to get the "id" columns:

SET @db:='id_new'; 

select @max_id:=max(AUTO_INCREMENT) from information_schema.tables;

select concat('update ',table_name,' set ', column_name,' = ',column_name,'+',@max_id,' ; ') from information_schema.columns where table_schema=@db and column_name like '%id' into outfile 'update_ids.sql';

use id_new
source update_ids.sql;

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/

You can accomplish this via layout weights. A weight dictates how the unclaimed portions of the screen are divided up. Give each EditText a layout_width of 0, and some proportional weight. I.e., give one a weight of 2, and the other a weight of 1 if you want the first to take up twice as much space.

Even i had the same problem . And the fault was with the "unsigned" marker in the FK's table PK

Based on the current user's latitude, longitude and the distance you wants to find,the sql query is given below.

SELECT * FROM(
    SELECT *,(((acos(sin((@latitude*pi()/180)) * sin((Latitude*pi()/180))+cos((@latitude*pi()/180)) * cos((Latitude*pi()/180)) * cos(((@longitude - Longitude)*pi()/180))))*180/pi())*60*1.1515*1.609344) as distance FROM Distances) t
WHERE distance <= @distance

@latitude and @longitude are the latitude and longitude of the point. Latitude and longitude are the columns of distances table. Value of pi is 22/7

Well, there's an alternate way! You can use a button instead of hyperlink. Hence, when the button is clicked the web page specified in "name_of_webpage" is opened in the target frame named "name_of_iframe". It works for me!

<form method="post" action="name_of_webpage" target="name_of_iframe">
<input type="submit" value="any_name_you_want" />
</form>
<iframe name="name_of_iframe"></iframe>

Yes the above answers describing the corect way to sort datatable

DataView dv = ft.DefaultView;
dv.Sort = "occr desc";
DataTable sortedDT = dv.ToTable();

But in addition to this, to select particular row in it you can use LINQ and try following

var Temp = MyDataSet.Tables[0].AsEnumerable().Take(1).CopyToDataTable();

You can generate the XML documentation file using either the command-line compiler or through the Visual Studio interface. If you are compiling with the command-line compiler, use options /doc or /doc+. That will generate an XML file by the same name and in the same path as the assembly. To specify a different file name, use /doc:file.

If you are using the Visual Studio interface, there's a setting that controls whether the XML documentation file is generated. To set it, double-click My Project in Solution Explorer to open the Project Designer. Navigate to the Compile tab. Find "Generate XML documentation file" at the bottom of the window, and make sure it is checked. By default this setting is on. It generates an XML file using the same name and path as the assembly.

In a .txt file opened with Notepad++,
press Ctrl-F
go in the tab "Replace"
write the regex pattern \|.+ in the space Find what
and let the space Replace with blank

Then tick the choice matches newlines after the choice Regular expression
and press two times on the Replace button

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

If you want result to be stored in another dataset:

df.drop_duplicates(keep=False)

or

df.drop_duplicates(keep=False, inplace=False)

If same dataset needs to be updated:

df.drop_duplicates(keep=False, inplace=True)

Above examples will remove all duplicates and keep one, similar to DISTINCT * in SQL

git stash is your friend.

If you have not made the commit yet, just run git stash. This will save away all of your changes.

Switch to the branch you want the changes on and run git stash pop.

There are lots of uses for git stash. This is certainly one of the more useful reasons.

An example:

# work on some code
git stash
git checkout correct-branch
git stash pop

This is preferred approach in most cases:

 File.open(yourfile, 'w') { |file| file.write("your text") }

When a block is passed to File.open, the File object will be automatically closed when the block terminates.

If you don't pass a block to File.open, you have to make sure that file is correctly closed and the content was written to file.

begin
  file = File.open("/tmp/some_file", "w")
  file.write("your text") 
rescue IOError => e
  #some error occur, dir not writable etc.
ensure
  file.close unless file.nil?
end

You can find it in documentation:

static VALUE rb_io_s_open(int argc, VALUE *argv, VALUE klass)
{
    VALUE io = rb_class_new_instance(argc, argv, klass);
    if (rb_block_given_p()) {
        return rb_ensure(rb_yield, io, io_close, io);
    }
    return io;
}

Two possibilities I can think of, although they are both mentioned in the link you referenced:

1. You're not specifying the correct SSH keypair file or user name in the ssh command you're using to log into the server:

   ssh -i [full path to keypair file] root@[EC2 instance hostname or IP address]

2. You don't have the correct permissions on the keypair file; you should use

   chmod 600 [keypair file]

to ensure that only you can read or write the file.

Try using the -v option with ssh to get more info on where exactly it's failing, and post back here if you''d like more help.

[Update]: OK, so this is what you should have seen if everything was set up properly:

debug1: Authentications that can continue: publickey,gssapi-with-mic
debug1: Next authentication method: publickey
debug1: Trying private key: ec2-keypair
debug1: read PEM private key done: type RSA
debug1: Authentication succeeded (publickey).

Are you running the ssh command from the directory containing the ec2-keypair file ? If so, try specifying -i ./ec2-keypair just to eliminate path problems. Also check "ls -l [full path to ec2-keypair]" file and make sure the permissions are 600 (displayed as rw-------). If none of that works, I'd suspect the contents of the keypair file, so try recreating it using the steps in your link.

Add -lrt to the end of g++ command line. This links in the librt.so "Real Time" shared library.

==========Advise==========

@martin clayton Answer is correct, But this is an advise only.

Please avoid the use of ambiguous variable in the stored procedure.

Example :

SELECT Id, dateCreated
INTO id, datecreated
FROM products
WHERE pName = iName

The above example will cause an error (null value error)

Example give below is correct. I hope this make sense.

Example :

SELECT Id, dateCreated
INTO val_id, val_datecreated
FROM products
WHERE pName = iName

You can also make them unambiguous by referencing the table, like:

[ Credit : maganap ]

SELECT p.Id, p.dateCreated INTO id, datecreated FROM products p 
WHERE pName = iName

Make use of Parameter Grouping (Laravel 4.2). For your example, it'd be something like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

Here's my general-purpose function which parametrizes the CSS selector and rules, and optionally takes in a css filename (case-sensitive) if you wish to add to a particular sheet instead (otherwise, if you don't provide a CSS filename, it will create a new style element and append it to the existing head. It will make at most one new style element and re-use it on future function calls). Works with FF, Chrome, and IE9+ (maybe earlier too, untested).

function addCssRules(selector, rules, /*Optional*/ sheetName) {
    // We want the last sheet so that rules are not overridden.
    var styleSheet = document.styleSheets[document.styleSheets.length - 1];
    if (sheetName) {
        for (var i in document.styleSheets) {
            if (document.styleSheets[i].href && document.styleSheets[i].href.indexOf(sheetName) > -1) {
                styleSheet = document.styleSheets[i];
                break;
            }
        }
    }
    if (typeof styleSheet === 'undefined' || styleSheet === null) {
        var styleElement = document.createElement("style");
        styleElement.type = "text/css";
        document.head.appendChild(styleElement);
        styleSheet = styleElement.sheet;
    }

    if (styleSheet) {
        if (styleSheet.insertRule)
            styleSheet.insertRule(selector + ' {' + rules + '}', styleSheet.cssRules.length);
        else if (styleSheet.addRule)
            styleSheet.addRule(selector, rules);
    }
}

below command worked in my debain 10 box!

root@debian:/home/arun# readlink -f $(which java)
/usr/lib/jvm/java-11-openjdk-amd64/bin/java

A simple example:

import java.util.Scanner;

public class Example
{
    public static void main(String[] args)
    {
        int number1, number2, sum;

        Scanner input = new Scanner(System.in);

        System.out.println("Enter First multiple");
        number1 = input.nextInt();

        System.out.println("Enter second multiple");
        number2 = input.nextInt();

        sum = number1 * number2;

        System.out.printf("The product of both number is %d", sum);
    }
}

Try this:

val date = Calendar.getInstance().time
val formatter = SimpleDateFormat.getDateTimeInstance() //or use getDateInstance()
val formatedDate = formatter.format(date)

You can use your own pattern as well, e.g.

val sdf = SimpleDateFormat("yyyy.MM.dd")
// 2020.02.02

To get local formatting use getDateInstance(), getDateTimeInstance(), or getTimeInstance(), or use new SimpleDateFormat(String template, Locale locale) with for example Locale.US for ASCII dates. The first three options require API level 29.

int id = getResources().getIdentifier("gameover", "drawable", getPackageName());
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams vp = 
    new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                    LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(vp);        
imageView.setImageResource(id);        
someLinearLayout.addView(imageView); 

There is a general problem: it's hard to mock time. Also, it's really bad practice to place long running/waiting code in a unit test.

So, for making a scheduling API testable, I used an interface with a real and a mock implementation like this:

public interface Clock {
    
    public long getCurrentMillis();
    
    public void sleep(long millis) throws InterruptedException;
    
}

public static class SystemClock implements Clock {

    @Override
    public long getCurrentMillis() {
        return System.currentTimeMillis();
    }

    @Override
    public void sleep(long millis) throws InterruptedException {
        Thread.sleep(millis);
    }
    
}

public static class MockClock implements Clock {

    private final AtomicLong currentTime = new AtomicLong(0);
    

    public MockClock() {
        this(System.currentTimeMillis());
    }
    
    public MockClock(long currentTime) {
        this.currentTime.set(currentTime);
    }
    

    @Override
    public long getCurrentMillis() {
        return currentTime.addAndGet(5);
    }

    @Override
    public void sleep(long millis) {
        currentTime.addAndGet(millis);
    }
    
}

With this, you could imitate time in your test:

@Test
public void testExpiration() {
    MockClock clock = new MockClock();
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExpiration("foo", 1000);
    clock.sleep(2000) // wait for 2 seconds
    assertNull(sco.getIfNotExpired("foo"));
}

An advanced multi-threading mock for Clock is much more complex, of course, but you can make it with ThreadLocal references and a good time synchronization strategy, for example.

I sugges to use the Apache Commons CSV https://commons.apache.org/proper/commons-csv/

Here is one example:

    Path currentRelativePath = Paths.get("");
    String currentPath = currentRelativePath.toAbsolutePath().toString();
    String csvFile = currentPath + "/pathInYourProject/test.csv";

    Reader in;
    Iterable<CSVRecord> records = null;
    try
    {
        in = new FileReader(csvFile);
        records = CSVFormat.EXCEL.withHeader().parse(in); // header will be ignored
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }

    for (CSVRecord record : records) {
        String line = "";
        for ( int i=0; i < record.size(); i++)
        {
            if ( line == "" )
                line = line.concat(record.get(i));
            else
                line = line.concat("," + record.get(i));
        }
        System.out.println("read line: " + line);
    }

It automaticly recognize , and " but not ; (maybe it can be configured...).

My example file is:

col1,col2,col3
val1,"val2",val3
"val4",val5
val6;val7;"val8"

And output is:

read line: val1,val2,val3
read line: val4,val5
read line: val6;val7;"val8"

Last line is considered like one value.

I made a simple wrapper for the Fullscreen API, called screenfull.js, to smooth out the prefix mess and fix some inconsistencies in the different implementations. Check out the demo to see how the Fullscreen API works.

This is TypeScript version of @Joel's answer. It is usable after Node 11.0:

import { promises as fs } from 'fs';

async function loadMonoCounter() {
    const data = await fs.readFile('monolitic.txt', 'binary');
    return Buffer.from(data);
}

Without eval:

Your original string was not an actual string.

jsonObj = "{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}"

The easiest way to to wrap it all with a single quote.

 jsonObj = '"{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}"'

Then you can combine two steps to parse it to JSON:

 $.parseJSON(jsonObj.slice(1,-1))

The size in bits of long on Windows platforms is 32 bits (4 bytes).

You can check this using sizeof(long).

I just want to point out that most of the answers here don't work, I am new to NodeJS and IDK if throughout time the "module.exports.yourClass" method changed, or if people just entered the wrong answer.

// MyClass

module.exports.Ninja = class Ninja{
    test(){
        console.log('TESTING 1... 2... 3...');
    };
}

//Using MyClass in seprate File


const ninjaFw = require('./NinjaFw');

let ninja = new ninjaFw.Ninja();
ninja.test();

• This is the method I am currently using. I like this syntax, becuase module.exports sits on the same line as the class declaration and that cleans the code up a little imo. The other way you can do it is like this:

//  Ninja Framework File


class Ninja{
    test(){
        console.log('TESTING 1... 2... 3...');
    };
}


module.exports.Ninja = Ninja;

• Two different syntax but, in the end, the same result. Just a matter of syntax anesthetics.

I think this suits perfect for any color you have:

a {
    color: inherit;
}

Update

With ES6, this is possible in exactly the manner you have described; a detailed description can be found in the documentation.

Old answer

Default parameters in JavaScript can be implemented in mainly two ways:

function myfunc(a, b)
{
    // use this if you specifically want to know if b was passed
    if (b === undefined) {
        // b was not passed
    }
    // use this if you know that a truthy value comparison will be enough
    if (b) {
        // b was passed and has truthy value
    } else {
        // b was not passed or has falsy value
    }
    // use this to set b to a default value (using truthy comparison)
    b = b || "default value";
}

The expression b || "default value" evaluates the value AND existence of b and returns the value of "default value" if b either doesn't exist or is falsy.

Alternative declaration:

function myfunc(a)
{
    var b;

    // use this to determine whether b was passed or not
    if (arguments.length == 1) {
        // b was not passed
    } else {
        b = arguments[1]; // take second argument
    }
}

The special "array" arguments is available inside the function; it contains all the arguments, starting from index 0 to N - 1 (where N is the number of arguments passed).

This is typically used to support an unknown number of optional parameters (of the same type); however, stating the expected arguments is preferred!

Further considerations

Although undefined is not writable since ES5, some browsers are known to not enforce this. There are two alternatives you could use if you're worried about this:

b === void 0;
typeof b === 'undefined'; // also works for undeclared variables

I had what at first seemed to be an identical problem, but it turned out to be due to an NHibernate/WPF compatibility issue. The problem was caused by the way WPF checks for object equality. I was able to get my stuff to work by using the object ID property in the SelectedValue and SelectedValuePath properties.

<ComboBox Name="CategoryList"
          DisplayMemberPath="CategoryName"
          SelectedItem="{Binding Path=CategoryParent}"
          SelectedValue="{Binding Path=CategoryParent.ID}"
          SelectedValuePath="ID">

See the blog post from Chester, The WPF ComboBox - SelectedItem, SelectedValue, and SelectedValuePath with NHibernate, for details.

@olleh answer worked because npm install will create a node_modules directory in the current path where it is executed. So, while using the file server system module, the below declaration locate files from the top level directory of node_modules.

const fs = require('fs')

After you tried Clean and Rebuild without success, check your res folder for corrupted files.

In my case a corrupted .png file caused all the trouble.

Using Apache ArrayUtils downloadable at this link you can easy use the method

subarray(boolean[] array, int startIndexInclusive, int endIndexExclusive) 

"boolean" is only an example, there are methods for all primitives java types

sending mail in php is not a one-step process. mail() returns true/false, but even if it returns true, it doesn't mean the message is going to be sent. all mail() does is add the message to the queue(using sendmail or whatever you set in php.ini)

there is no reliable way to check if the message has been sent in php. you will have to look through the mail server logs.

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

Using .data() will only add data to the jQuery object for that element. In order to add the information to the element itself you need to access that element using jQuery's .attr or native .setAttribute

$('div').attr('data-info', 1);
$('div')[0].setAttribute('data-info',1);

In order to access an element with the attribute set, you can simply select based on that attribute as you note in your post ($('div[data-info="1"]')), but when you use .data() you cannot. In order to select based on the .data() setting, you would need to use jQuery's filter function.

jsFiddle Demo

$('div').data('info', 1);_x000D_
//alert($('div').data('info'));//1_x000D_
_x000D_
$('div').filter(function(){_x000D_
   return $(this).data('info') == 1; _x000D_
}).text('222');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div>1</div>

Use Iterators...

var myarray = ['hello', ' hello again'];
processArray(myarray[Symbol.iterator](), () => {
    console.log('all done')
})
function processArray(iter, cb) {
    var curr = iter.next()
    if(curr.done)
        return cb()
    console.log(curr.value)
    processArray(iter, cb)
}

From other post:

    find /c "string" file >NUL
    if %errorlevel% equ 1 goto notfound
        echo found
    goto done
    :notfound
        echo notfound
    goto done
    :done

Use the /i switch when you want case insensitive checking:

    find /i /c "string" file >NUL

Or something like: if not found write to file.

    find /c "%%P" file.txt  || ( echo %%P >> newfile.txt )

Or something like: if found write to file.

    find /c "%%P" file.txt  && ( echo %%P >> newfile.txt )

Or something like:

    find /c "%%P" file.txt  && ( echo found ) || ( echo not found )

the way i found was to find the project compiler output (project structure > project). then find the complied folder of the module you wish to turn to a jar, compress it with zip and change the extension of the output from zip to jar.

My PC is running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes. You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:

<?php echo phpinfo(); ?>

There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from

PHPIniDir 'c:\PHP\'

to

PHPIniDir 'c:\PHP'

Pay the attention that the last slash disturbed everything!

Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!

Try changing your code to this:

private void Test()
{            
    System.IO.MemoryStream data = new System.IO.MemoryStream(TestStream());

    byte[] buf = new byte[data.Length];
    data.Read(buf, 0, buf.Length);                       
}

For those that just used a standard form submit (non-AJAX), there's another way to fire some Javascript/JQuery code upon completion of your action.

First, create a string property on your Model.

public class MyModel 
{
    public string JavascriptToRun { get; set;}
}

Now, bind to your new model property in the Javascript of your view:

<script type="text/javascript">
     @Model.JavascriptToRun
</script>

Now, also in your view, create a Javascript function that does whatever you need to do:

<script type="text/javascript">
     @Model.JavascriptToRun

     function ShowErrorPopup() {
          alert('Sorry, we could not process your order.');
     }

</script>

Finally, in your controller action, you need to call this new Javascript function:

[HttpPost]
public ActionResult PurchaseCart(MyModel model)
{
    // Do something useful
    ...

    if (success == false)
    {
        model.JavascriptToRun= "ShowErrorPopup()";
        return View(model);
    }
    else
        return RedirectToAction("Success");
}

Functions are first class objects that can be:

• Defined within your function
• Created just like any other variable or object at any point in your function
• Returned from your function (which may seem obvious after the two above, but still)

To build on the example given by Kenny:

   function a(x) {
      var w = function b(y) {
        return x + y;
      }
      return w;
   };

   var returnedFunction = a(3);
   alert(returnedFunction(2));

Would alert you with 5.

Non-VBA Solution:

You need to make an additional group of data for each color group that represent the Y values for that particular group. You can use these groups to make multiple data sets within your graph.

Here is an example using your data:

     A       B        C        D                    E                        F                            G
----------------------------------------------------------------------------------------------------------------------
1| COMPANY  XVALUE   YVALUE   GROUP                 Red                     Orange                       Green
2| Apple     45       35       red         =IF($D2="red",$C2,NA()) =IF($D2="orange",$C2,NA()) =IF($D2="green",$C2,NA())
3| Xerox     45       38       red         =IF($D3="red",$C3,NA()) =IF($D3="orange",$C3,NA()) =IF($D3="green",$C3,NA())
4| KMart     63       50       orange      =IF($D4="red",$C4,NA()) =IF($D4="orange",$C4,NA()) =IF($D4="green",$C4,NA())
5| Exxon     53       59       green       =IF($D5="red",$C5,NA()) =IF($D5="orange",$C5,NA()) =IF($D5="green",$C5,NA())

It should look like this afterwards:

     A       B        C        D          E           F          G
---------------------------------------------------------------------
1| COMPANY  XVALUE   YVALUE   GROUP       Red         Orange     Green
2| Apple     45       35       red         35         #N/A       #N/A    
3| Xerox     45       38       red         38         #N/A       #N/A
4| KMart     63       50       orange     #N/A         50        #N/A
5| Exxon     53       59       green      #N/a        #N/A        59

Now you can generate your graph using different data sets. Here is a picture showing just this example data:

You can change the series (X;Y) values to B:B ; E:E, B:B ; F:F, B:B ; G:G respectively, to make it so the graph is automatically updated when you add more data.

This works for me on the Northwind sample DB, note that SearchLetter has 2 characters to it and SearchLetter also has to be declared for this to run:

declare @SearchLetter2 char(2)
declare @SearchLetter char(1)
Set @SearchLetter = 'A'
Set @SearchLetter2 = @SearchLetter+'%'
select * from Customers where ContactName like @SearchLetter2 and Region='WY'

I'm adding this because it's not mentioned in any of the other answers. You can give a container a specific hostname at runtime with the -h directive.

docker run -h=my.docker.container.example.com ubuntu:latest

You can use backticks (or whatever equivalent your shell uses) to get the output of hosthame into the -h argument.

docker run -h=`hostname` ubuntu:latest

There is a caveat, the value of hostname will be taken from the host you run the command from, so if you want the hostname of a virtual machine that's running your docker container then using hostname as an argument may not be correct if you are using the host machine to execute docker commands on the virtual machine.

Push always unique value in array

ab = [
     {"id":"1","val":"value1"},
     {"id":"2","val":"value2"},
     {"id":"3","val":"value3"}
   ];



var clickId = [];
var list = JSON.parse(ab);
$.each(list, function(index, value){
    if(clickId.indexOf(value.id) < 0){
        clickId.push(value.id);
    }
});

For me this issue only occurred on Android < 4.0

The combination of parameters I used were:

android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"

The maxLines count seemed to be the random final piece that made my TextView wrap.

Render Line Endings is a VS Code extension that is still actively maintained (as of Apr 2020):

https://marketplace.visualstudio.com/items?itemName=medo64.render-crlf

https://github.com/medo64/render-crlf/

It can be configured like this:

{
    "editor.renderWhitespace": "all",
    "code-eol.newlineCharacter": "¬",
    "code-eol.returnCharacter" : "¤",
    "code-eol.crlfCharacter"   : "¤¬",
}

and looks like this:

This works for me:

Console.OutputEncoding = System.Text.Encoding.Default;

To display some of the symbols, it's required to set Command Prompt's font to Lucida Console:

1. Open Command Prompt;

2. Right click on the top bar of the Command Prompt;

3. Click Properties;

4. If the font is set to Raster Fonts, change it to Lucida Console.

While you should probably use one of the many SQLite wrappers, if you wanted to know how to call the SQLite library yourself, you would:

1. Configure your Swift project to handle SQLite C calls. If using Xcode 9 or later, you can simply do:

   import SQLite3
   

2. Create/open database.

   let fileURL = try! FileManager.default
       .url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
       .appendingPathComponent("test.sqlite")
   
   // open database
   
   var db: OpaquePointer?
   guard sqlite3_open(fileURL.path, &db) == SQLITE_OK else {
       print("error opening database")
       sqlite3_close(db)
       db = nil
       return
   }
   

   Note, I know it seems weird to close the database upon failure to open, but the sqlite3_open documentation makes it explicit that we must do so to avoid leaking memory:

   Whether or not an error occurs when it is opened, resources associated with the database connection handle should be released by passing it to sqlite3_close() when it is no longer required.

3. Use sqlite3_exec to perform SQL (e.g. create table).

   if sqlite3_exec(db, "create table if not exists test (id integer primary key autoincrement, name text)", nil, nil, nil) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error creating table: \(errmsg)")
   }
   

4. Use sqlite3_prepare_v2 to prepare SQL with ? placeholder to which we'll bind value.

   var statement: OpaquePointer?
   
   if sqlite3_prepare_v2(db, "insert into test (name) values (?)", -1, &statement, nil) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error preparing insert: \(errmsg)")
   }
   
   if sqlite3_bind_text(statement, 1, "foo", -1, SQLITE_TRANSIENT) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure binding foo: \(errmsg)")
   }
   
   if sqlite3_step(statement) != SQLITE_DONE {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure inserting foo: \(errmsg)")
   }
   

   Note, that uses the SQLITE_TRANSIENT constant which can be implemented as follows:

   internal let SQLITE_STATIC = unsafeBitCast(0, to: sqlite3_destructor_type.self)
   internal let SQLITE_TRANSIENT = unsafeBitCast(-1, to: sqlite3_destructor_type.self)
   

5. Reset SQL to insert another value. In this example, I'll insert a NULL value:

   if sqlite3_reset(statement) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error resetting prepared statement: \(errmsg)")
   }
   
   if sqlite3_bind_null(statement, 1) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure binding null: \(errmsg)")
   }
   
   if sqlite3_step(statement) != SQLITE_DONE {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure inserting null: \(errmsg)")
   }
   

6. Finalize prepared statement to recover memory associated with that prepared statement:

   if sqlite3_finalize(statement) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error finalizing prepared statement: \(errmsg)")
   }
   
   statement = nil
   

7. Prepare new statement for selecting values from table and loop through retrieving the values:

   if sqlite3_prepare_v2(db, "select id, name from test", -1, &statement, nil) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error preparing select: \(errmsg)")
   }
   
   while sqlite3_step(statement) == SQLITE_ROW {
       let id = sqlite3_column_int64(statement, 0)
       print("id = \(id); ", terminator: "")
   
       if let cString = sqlite3_column_text(statement, 1) {
           let name = String(cString: cString)
           print("name = \(name)")
       } else {
           print("name not found")
       }
   }
   
   if sqlite3_finalize(statement) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error finalizing prepared statement: \(errmsg)")
   }
   
   statement = nil
   

8. Close database:

   if sqlite3_close(db) != SQLITE_OK {
       print("error closing database")
   }
   
   db = nil
   

For Swift 2 and older versions of Xcode, see previous revisions of this answer.

The code helped me to fulfill my requirement.

I have made some modifications and using a form I completed this. Here is my code-

Need a 'target' attribute for 'form' -- that's it!

Form

<form id="view_form" name="view_form" method="post" action="view_report.php"  target="Map" >
  <input type="text" value="<?php echo $sale->myvalue1; ?>" name="my_value1"/>
  <input type="text" value="<?php echo $sale->myvalue2; ?>" name="my_value2"/>
  <input type="button" id="download" name="download" value="View report" onclick="view_my_report();"   /> 
</form>

JavaScript

function view_my_report() {     
   var mapForm = document.getElementById("view_form");
   map=window.open("","Map","status=0,title=0,height=600,width=800,scrollbars=1");

   if (map) {
      mapForm.submit();
   } else {
      alert('You must allow popups for this map to work.');
   }
}

Full code is explained showing normal form and form elements.

Just came across this and the short code for transparency is simply #00000000.

Looking at https://stackoverflow.com/a/39144104/2914140 I simplified a bit:

// In onCreateView():
view.edit_text.run {
    requestFocus()
    post { showKeyboard(this) }
}

fun showKeyboard(view: View) {
    val imm = view.context.getSystemService(
        Context.INPUT_METHOD_SERVICE) as InputMethodManager?
    imm?.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
}

It is better than https://stackoverflow.com/a/11155404/2914140:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

because when you press Home button and move to home screen, the keyboard will stay open.

You can easily define such function and use it then:

ifnull <- function(x,y) {
  if(is.na(x)==TRUE) 
    return (y)
  else 
    return (x);
}

or same minified version:

ifnull <- function(x,y) {if(is.na(x)==TRUE) return (y) else return (x);}

That code gets you the IP address of your server not the address of the client who is accessing your website. Use the HttpContext.Current.Request.UserHostAddress property to the client's IP address.

You can just delete .git. Typically:

rm -rf .git

Then, recreate as the right user.

For anything below Honeycomb (API Level 11) you'll have to use setLayoutParams(...).

If you can limit your support to Honeycomb and up you can use the setX(...), setY(...), setLeft(...), setTop(...), etc.

If you don't want to wrap a table under any div:

table{
  table-layout: fixed;
}
tbody{
      display: block;
    overflow: auto;
}

With AppCompat (22.1.1+) you can add a style like this:

<style name="MyGreenButton">
    <item name="colorButtonNormal">#009900</item>
</style>

And use it by just applying the style:

<android.support.v7.widget.AppCompatButton
    style="@style/MyGreenButton"
    android:layout_width="match_width"
    android:layout_height="wrap_content"
    android:text="A Green Button"
    />

Programmatically changing the color, I found that the only way to update the color (on API 15 or 16) was to use the 'background tint list' instead. And it doesn't remove the nice radial animation on API 21 devices:

ColorStateList colorStateList = new ColorStateList(new int[][] {{0}}, new int[] {0xFF009900}); // 0xAARRGGBB
button.setSupportBackgroundTintList(colorStateList);

Because button.setBackground(...) and button.getBackground().mutate().setColorFilter(...) do not change the button color on API 15 and 16 like they do on API 21.

NoneType means that instead of an instance of whatever Class or Object you think you're working with, you've actually got None. That usually means that an assignment or function call up above failed or returned an unexpected result.

This is a project that it can serialize(JSON base now) all data in your model and put them to a specific directory automatically and then it can deserialize it whenever you want... I've personally serialized thousand records with this script and then load all of them back to another database without any losing data.

Anyone that would be interested in opensource projects can contribute this project and add more feature to it.

According to this nice FAQ there are a couple solutions.

You might also be able to escape the ampersand with the backslash character \ if you can modify the comment.

We can pretend they are filenames and remove extensions:

tools::file_path_sans_ext(a)
# [1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"

you can use this method : https://stackoverflow.com/a/31804061/3343174 it's converting perfectly any hexadecimal number (presented as a string) to a decimal number

Simplest version, assuming you're working on the same branch that the file you want is on:

git checkout path/to/file.

I do this so often that I've got an alias set to gc='git checkout'.

This is my solution using pure Win32/C++ based on the top answer. The idea is to wrap everything required into one function without the need for external callback functions or structures:

#include <utility>

HWND FindTopWindow(DWORD pid)
{
    std::pair<HWND, DWORD> params = { 0, pid };

    // Enumerate the windows using a lambda to process each window
    BOOL bResult = EnumWindows([](HWND hwnd, LPARAM lParam) -> BOOL 
    {
        auto pParams = (std::pair<HWND, DWORD>*)(lParam);

        DWORD processId;
        if (GetWindowThreadProcessId(hwnd, &processId) && processId == pParams->second)
        {
            // Stop enumerating
            SetLastError(-1);
            pParams->first = hwnd;
            return FALSE;
        }

        // Continue enumerating
        return TRUE;
    }, (LPARAM)&params);

    if (!bResult && GetLastError() == -1 && params.first)
    {
        return params.first;
    }

    return 0;
}

Besides put all your assets in the public folder, you can use the HTML::image() Method, and only needs an argument which is the path to the image, relative on the public folder, as well:

{{ HTML::image('imgs/picture.jpg') }}

Which generates the follow HTML code:

<img src="http://localhost:8000/imgs/picture.jpg">

The link to other elements of HTML::image() Method: http://laravel-recipes.com/recipes/185/generating-an-html-image-element

Something like this should work (suggested by orip):

ssh-agent bash -c 'ssh-add /somewhere/yourkey; git clone [email protected]:user/project.git'

if you prefer subshells, you could try the following (though it is more fragile):

ssh-agent $(ssh-add /somewhere/yourkey; git clone [email protected]:user/project.git)

Git will invoke SSH which will find its agent by environment variable; this will, in turn, have the key loaded.

Alternatively, setting HOME may also do the trick, provided you are willing to setup a directory that contains only a .ssh directory as HOME; this may either contain an identity.pub, or a config file setting IdentityFile.

giving permision 400 makes the key private and not accessible by someone unknown. It makes the key as a protected one.

chmod 400 /Users/tudouya/.ssh/vm/vm_id_rsa.pub

Since this is still the first result on the Googler when searching how to remove all modules in NPM, I figured I'd share a small script for Powershell to remove all dependencies through NPM:

#Create a Packages Array to add package names to
$Packages = New-Object System.Collections.ArrayList

#Get all Production Dependencies by name
(Get-Content .\Package.json | ConvertFrom-JSON).dependencies.psobject.properties.name |
ForEach-Object { $Packages.Add($_) | Out-Null }

#Get all Dev Dependencies by name
(Get-Content .\Package.json | ConvertFrom-JSON).devDependencies.psobject.properties.name | 
ForEach-Object { $Packages.Add($_) | Out-Null }

#Remove each package individually
Foreach($Package in ($Packages | select -unique))
{ npm uninstall $Package }

#Clean up any remaining packages
$Modules = Get-ChildItem "node_modules"
if($Modules)
{ $Modules | ForEach-Object { Remove-Item ".\node_modules\$_" -Force -Recurse } }

This runs a more specific removal, rather than removing each module from node_modules individually.

The best use case I can think of is in caching AJAX responses. Here's a modified example from Rebecca Murphey's intro post on the topic:

var cache = {};

function getData( val ){

    // return either the cached value or jqXHR object wrapped Promise
    return $.when(
        cache[ val ] || 
        $.ajax('/foo/', {
            data: { value: val },
            dataType: 'json',
            success: function( resp ){
                cache[ val ] = resp;
            }
        })
    );
}

getData('foo').then(function(resp){
    // do something with the response, which may
    // or may not have been retrieved using an
    // XHR request.
});

Basically, if the value has already been requested once before it's returned immediately from the cache. Otherwise, an AJAX request fetches the data and adds it to the cache. The $.when/.then doesn't care about any of this; all you need to be concerned about is using the response, which is passed to the .then() handler in both cases. jQuery.when() handles a non-Promise/Deferred as a Completed one, immediately executing any .done() or .then() on the chain.

Deferreds are perfect for when the task may or may not operate asynchronously, and you want to abstract that condition out of the code.

Another real world example using the $.when helper:

$.when($.getJSON('/some/data/'), $.get('template.tpl')).then(function (data, tmpl) {

    $(tmpl) // create a jQuery object out of the template
    .tmpl(data) // compile it
    .appendTo("#target"); // insert it into the DOM

});

TS gets compiled to JS which then executed. Therefore you have access to all of the objects in the JS runtime. One of those objects is the JSON object. This contains the following methods:

• JSON.parse() method parses a JSON string, constructing the JavaScript value or object described by the string.
• JSON.stringify() method converts a JavaScript object or value to a JSON string.

Example:

const jsonString = '{"employee":{ "name":"John", "age":30, "city":"New York" }}';_x000D_
_x000D_
_x000D_
const JSobj = JSON.parse(jsonString);_x000D_
_x000D_
console.log(JSobj);_x000D_
console.log(typeof JSobj);_x000D_
_x000D_
const JSON_string = JSON.stringify(JSobj);_x000D_
_x000D_
console.log(JSON_string);_x000D_
console.log(typeof JSON_string);

The org.apache.http classes and the AndroidHttpClient class have been deprecated in Android 5.1. These classes are no longer being maintained and you should migrate any app code using these APIs to the URLConnection classes as soon as possible.

https://developer.android.com/about/versions/android-5.1.html#http

Thought of sharing my code using HttpUrlConnection

public String  performPostCall(String requestURL,
        HashMap<String, String> postDataParams) {

    URL url;
    String response = "";
    try {
        url = new URL(requestURL);

        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setReadTimeout(15000);
        conn.setConnectTimeout(15000);
        conn.setRequestMethod("GET");
        conn.setDoInput(true);
        conn.setDoOutput(true);


        OutputStream os = conn.getOutputStream();
        BufferedWriter writer = new BufferedWriter(
                new OutputStreamWriter(os, "UTF-8"));
        writer.write(getPostDataString(postDataParams));

        writer.flush();
        writer.close();
        os.close();
        int responseCode=conn.getResponseCode();

        if (responseCode == HttpsURLConnection.HTTP_OK) {
            String line;
            BufferedReader br=new BufferedReader(new InputStreamReader(conn.getInputStream()));
            while ((line=br.readLine()) != null) {
                response+=line;
            }
        }
        else {
            response="";    

        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return response;
}

...

private String getPostDataString(HashMap<String, String> params) throws UnsupportedEncodingException{
        StringBuilder result = new StringBuilder();
        boolean first = true;
        for(Map.Entry<String, String> entry : params.entrySet()){
            if (first)
                first = false;
            else
                result.append("&");

            result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
        }

        return result.toString();
    }

also you can Post method :

conn.setRequestMethod("POST");

Update 21/02/2016

UPDATE 24/08/2016

Use some best library , such as :

• Retrofit
• Volley

because :

• Avoid HttpUrlConnection and HttpClient

On lower API levels (mostly on Gingerbread and Froyo), HttpUrlConnection and HttpClient are far from being perfect

• And Avoid AsyncTask Too
• They are Much Faster
• They Caches Everything

Since the introduction of Honeycomb (API 11), it's been mandatory to perform network operations on a separate thread, different from the main thread

If the starting cell of the range and of the key is static, the solution can be very simple:

Range("A3").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Sort key1:=Range("B3", Range("B3").End(xlDown)), _
order1:=xlAscending, Header:=xlNo

On Windows, Subversion stores the auth data in %APPDATA%\Subversion\auth. The passwords however are stored encrypted, not in plaintext.

You can decrypt those, but only if you log in to Windows as the same user for which the auth data was saved.

Someone even wrote a tool to decrypt those. Never tried the tool myself so I don't know how well it works, but you might want to try it anyway:

http://www.leapbeyond.com/ric/TSvnPD/

Update: In TortoiseSVN 1.9 and later, you can do it without any additional tools:

Settings Dialog -> Saved Data, then click the "Clear..." button right of the text "Authentication Data". A new dialog pops up, showing all stored authentication data where you can chose which one(s) to clear. Instead of clearing, hold down the Shift and Ctrl button, and then double click on the list. A new column is shown in the dialog which shows the password in clear.

I have not tested this code. I have used similar code and it works. The syntax is in Oracle.

If you are getting this from your own package.json, just add the repository field to it. (use the link to your actual repository):

"repository" : { 
   "type" : "git",
   "url" : "https://github.com/npm/npm.git"
 }

I wrote a small lib for this. https://www.npmjs.com/package/@inf3rno/promise.exposed

I used the factory method approach others wrote, but I overrode the then, catch, finally methods too, so you can resolve the original promise by those as well.

Resolving Promise without executor from outside:

const promise = Promise.exposed().then(console.log);
promise.resolve("This should show up in the console.");

Racing with the executor's setTimeout from outside:

const promise = Promise.exposed(function (resolve, reject){
    setTimeout(function (){
        resolve("I almost fell asleep.")
    }, 100000);
}).then(console.log);

setTimeout(function (){
    promise.resolve("I don't want to wait that much.");
}, 100);

There is a no-conflict mode if you don't want to pollute the global namespace:

const createExposedPromise = require("@inf3rno/promise.exposed/noConflict");
const promise = createExposedPromise().then(console.log);
promise.resolve("This should show up in the console.");

For linux and Windows: Just modify 1 line, and you can change it.

1. Open file

cwp.py

in

C:\Users\ [your computer name]\Anaconda2

.

2. find the line 

os.chdir(documents_folder)

at the end of the file.

Change it to

os.chdir("your expected working folder")

for example: os.chdir("D:/Jupyter_folder")

3. save and close.

It worked.

Update:

When it comes to MacOS, I couldn't find the cwp.py. Here is what I found:

Open terminal on your Macbook, run 'jupyter notebook --generate-config'.

It will create a config file at /Users/[your_username]/.jupyter/jupyter_notebook_config.py

Open the config file, then change this line #c.NotebookApp.notebook_dir = '' to c.NotebookApp.notebook_dir = 'your path' and remember un-comment this line too.

For example, I change my path to '/Users/catbuilts/JupyterProjects/'

When you want to differ between a superClass and the inheritedClass you can use:

if([myTestClass class] == [myInheritedClass class]){
   NSLog(@"I'm the inheritedClass);
} 
if([myTestClass class] == [mySuperClass class]){
   NSLog(@"I'm the superClass);
} 

Using - (BOOL)isKindOfClass:(Class)aClass in this case would result in TRUE both times because the inheritedClass is also a kind of the superClass.

BigInteger has a constructor where you can pass string as an argument.

try below,

private void sum(String newNumber) {
    // BigInteger is immutable, reassign the variable:
    this.sum = this.sum.add(new BigInteger(newNumber));
}

You need a public class for Form1 to initialize.

See this code:

namespace TimerApp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private int counter = 60;
        private void button1_Click(object sender, EventArgs e)
        {
            //Insert your code from before
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            //Again insert your code
        }
    }
}

I've tried this and it all worked fine

If you need anymore help feel free to comment :)

git rev-list --all | (
    while read revision; do
        git grep -F 'password' $revision
    done
)

I woudn't bother with the likelihood of collision. Just generate a random string and check if it exists. If it does, try again and you shouldn't need to do it more that a couple of times unless you have a huge number of plates already assigned.

Another solution for generating an 8-character long pseudo-random string in pure (My)SQL:

SELECT LEFT(UUID(), 8);

You can try the following (pseudo-code):

DO 
    SELECT LEFT(UUID(), 8) INTO @plate;
    INSERT INTO plates (@plate);
WHILE there_is_a_unique_constraint_violation
-- @plate is your newly assigned plate number

Since this post has received a unexpected level of attention, let me highlight ADTC's comment : the above piece of code is quite dumb and produces sequential digits.

For slightly less stupid randomness try something like this instead :

SELECT LEFT(MD5(RAND()), 8)

And for true (cryptograpically secure) randomness, use RANDOM_BYTES() rather than RAND() (but then I would consider moving this logic up to the application layer).

Here's another option for those not using heatmap.2 (aheatmap is good!)

Make a sequential vector of 100 values from min to max of your input matrix, find value closest to 0 in that, make two vector of colours to and from desired midpoint, combine and use them:

breaks <- seq(from=min(range(inputMatrix)), to=max(range(inputMatrix)), length.out=100)
midpoint <- which.min(abs(breaks - 0))
rampCol1 <- colorRampPalette(c("forestgreen", "darkgreen", "black"))(midpoint)
rampCol2 <- colorRampPalette(c("black", "darkred", "red"))(100-(midpoint+1))
rampCols <- c(rampCol1,rampCol2)

You were almost there.

Remove protected $dates = ['license_expire']

and then change your LicenseExpire accessor to:

public function getLicenseExpireAttribute($date)
{
    return Carbon::parse($date);
}

This way it will return a Carbon instance no matter what. So for your form you would just have $employee->license_expire->format('Y-m-d') (or whatever format is required) and diffForHumans() should work on your home page as well.

Hope this helps!

If your numbers are a, b and c then:

    int a = 1;
    int b = 2;
    int c = 3;

    int d =  a > b ? a : b;
    return c > d ? c : d;

This could turn into one of those "how many different ways can we do this" type questions!

This is a paragraph option. Go to Window>Paragraph then a small window will pop up. You will have two buttons on the bottom. One with a arrow on the left of P and one on the right. Select the right one.

NORMSINV (mentioned in a comment) is the inverse of the CDF of the standard normal distribution. Using scipy, you can compute this with the ppf method of the scipy.stats.norm object. The acronym ppf stands for percent point function, which is another name for the quantile function.

In [20]: from scipy.stats import norm

In [21]: norm.ppf(0.95)
Out[21]: 1.6448536269514722

Check that it is the inverse of the CDF:

In [34]: norm.cdf(norm.ppf(0.95))
Out[34]: 0.94999999999999996

By default, norm.ppf uses mean=0 and stddev=1, which is the "standard" normal distribution. You can use a different mean and standard deviation by specifying the loc and scale arguments, respectively.

In [35]: norm.ppf(0.95, loc=10, scale=2)
Out[35]: 13.289707253902945

If you look at the source code for scipy.stats.norm, you'll find that the ppf method ultimately calls scipy.special.ndtri. So to compute the inverse of the CDF of the standard normal distribution, you could use that function directly:

In [43]: from scipy.special import ndtri

In [44]: ndtri(0.95)
Out[44]: 1.6448536269514722

If you realy need to restart your app, you could write a separate app the start it...

This page provides many different examples for different scenarios:

http://www.rgagnon.com/javadetails/java-0014.html

Within Excel you need to set a reference to the VB script run-time library. The relevant file is usually located at \Windows\System32\scrrun.dll

• To reference this file, load the Visual Basic Editor (ALT+F11)
• Select Tools > References from the drop-down menu
• A listbox of available references will be displayed
• Tick the check-box next to 'Microsoft Scripting Runtime'
• The full name and path of the scrrun.dll file will be displayed below the listbox
• Click on the OK button.

This can also be done directly in the code if access to the VBA object model has been enabled.

Access can be enabled by ticking the check-box Trust access to the VBA project object model found at File > Options > Trust Center > Trust Center Settings > Macro Settings

To add a reference:

Sub Add_Reference()

    Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference

End Sub

To remove a reference:

Sub Remove_Reference()

Dim oReference As Object

    Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")

    Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference

End Sub

Modern browsers have support for document.getElementsByClassName. You can see the full breakdown of which vendors provide this functionality at caniuse. If you're looking to extend support into older browsers, you may want to consider a selector engine like that found in jQuery or a polyfill.

Older Answer

You'll want to check into jQuery, which will allow the following:

$(".classname").hide(); // hides everything with class 'classname'

Google offers a hosted jQuery source-file, so you can reference it and be up-and-running in moments. Include the following in your page:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
  $(function(){
    $(".classname").hide();
  });
</script>

l = ['a','b','a','c','a','d']
to_remove = [1, 3]
[l[i] for i in range(0, len(l)) if i not in to_remove])

It's basically the same as the top voted answer, just a different way of writing it. Note that using l.index() is not a good idea, because it can't handle duplicated elements in a list.

ENV['RAILS_ENV'] is now deprecated.

You should use Rails.env which is clearly much nicer.

printf("%05d", zipCode);

The 0 indicates what you are padding with and the 5 shows the width of the integer number.

Example 1: If you use "%02d" (useful for dates) this would only pad zeros for numbers in the ones column. E.g., 06 instead of 6.

Example 2: "%03d" would pad 2 zeros for one number in the ones column and pad 1 zero for a number in the tens column. E.g., number 7 padded to 007 and number 17 padded to 017.

Looking inside the .iml file of your project you will see the following line:

 <option name="ASSETS_FOLDER_RELATIVE_PATH" value="/src/main/assets" />

This means the "assets" folder is already declared for Gradle. You will need to create it under src/main/ (I'm using Android Studio 0.4.2).

You can try this query:

USE AdventureWorks
GO
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%myName%'

Try the strict equality comparison:

if(1 === true)
    document.write("oh!!! that's true");  //**this is not displayed**

The == operator does conversion from one type to another, the === operator doesn't.

Angular's own ng-Router takes URLs into consideration while routing, UI-Router takes states in addition to URLs.

States are bound to named, nested and parallel views, allowing you to powerfully manage your application's interface.

While in ng-router, you have to be very careful about URLs when providing links via <a href=""> tag, in UI-Router you have to only keep state in mind. You provide links like <a ui-sref="">. Note that even if you use <a href=""> in UI-Router, just like you would do in ng-router, it will still work.

So, even if you decide to change your URL some day, your state will remain same and you need to change URL only at .config.

While ngRouter can be used to make simple apps, UI-Router makes development much easier for complex apps. Here its wiki.

ALTER TABLE t_name modify c_name INT(10) AUTO_INCREMENT PRIMARY KEY;

If you just want to make sure a certain file exists (f.ex. because it shoud be created in a different way than via ansible) and fail if it doesn't, then you can do this:

- name: sanity check that /some/path/file exists
  command: stat /some/path/file
  check_mode: no # always run
  changed_when: false # doesn't change anything

My approach is using the attributes collection to add HTML data- attributes from code behind. This is more inline with jquery and client side scripting.

// This would likely be done with findControl in your grid OnItemCreated handler
LinkButton targetBtn = new LinkButton();


// Add attributes
targetBtn.Attributes.Add("data-{your data name here}", value.ToString() );
targetBtn.Attributes.Add("data-{your data name 2 here}", value2.ToString() );

Then retrieve the values through the attribute collection

string val = targetBtn.Attributes["data-{your data name here}"].ToString();

Actually it is the issue related to the app store. I have upload many build some time it takes time depend upon the size of the ipa and at which time you are uploading it to the App Store. Please use Application Loader 3.0 or higher to upload the build.

There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...

https://api.jquery.com/category/effects/

You can use slideDown just like this:

$("test").slideDown("slow");

And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.

arrOfObj.map(o => { 
  o.isActive = true; 
  return o; 
});

I had a similar problem to solve, here is a simple solution of how to pass variables to template files, the trick is to write the template file taking advantage of the variable. You need to create a dictionary (list is also possible), which holds the set of variables corresponding to each of the file. Then within the template file access them.

see below:

the template file: test_file.j2
# {{ ansible_managed }} created by [email protected]

{% set dkey  = (item | splitext)[0]  %}
{% set fname = test_vars[dkey].name  %}
{% set fip   = test_vars[dkey].ip    %}
{% set fport = test_vars[dkey].port  %}
filename: {{ fname }}
ip address: {{ fip }}
port: {{ fport }}

        port: 8002
      file_03:
        name: file_03.txt
        ip: 10.0.0.3
        port: 8003

  tasks:
    - name: copy the files
      template:
        src: test_file.j2

$("#e2").select2({
   placeholder: "Select a State",
   allowClear: true
});
$("#e2_2").select2({
   placeholder: "Select a State"
});

The placeholder can be declared via a data-placeholder attribute attached to the select, or via the placeholder configuration element as seen in the example code.

When placeholder is used for a non-multi-value select box, it requires that you include an empty tag as your first option.

Optionally, a clear button (visible once a selection is made) is available to reset the select box back to the placeholder value.

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

https://www.slideshare.net/InfoQ/amazon-dynamodb-design-patterns-best-practices https://www.slideshare.net/AmazonWebServices/awsome-day-2016-module-4-databases-amazon-dynamodb-and-amazon-rds https://ceyhunozgun.blogspot.com/2017/04/implementing-object-persistence-with-dynamodb.html

This problem is usually caused by writing to a connection that had already been closed by the peer. In this case it could indicate that the user cancelled the download for example.

Maps have also had factory methods added in Java 9. For up to 10 entries Maps have overloaded constructors that take pairs of keys and values. For example we could build a map of various cities and their populations (according to google in October 2016) as follow:

Map<String, Integer> cities = Map.of("Brussels", 1_139000, "Cardiff", 341_000);

The var-args case for Map is a little bit harder, you need to have both keys and values, but in Java, methods can’t have two var-args parameters. So the general case is handled by taking a var-args method of Map.Entry<K, V> objects and adding a static entry() method that constructs them. For example:

Map<String, Integer> cities = Map.ofEntries(
    entry("Brussels", 1139000), 
    entry("Cardiff", 341000)
);

Collection Factory Methods in Java 9

I'm not sure what you think this ORDER BY is accomplishing? Even if you do put ORDER BY in the view in a legal way (e.g. by adding a TOP clause), if you just select from the view, e.g. SELECT * FROM dbo.TopUsersTest; without an ORDER BY clause, SQL Server is free to return the rows in the most efficient way, which won't necessarily match the order you expect. This is because ORDER BY is overloaded, in that it tries to serve two purposes: to sort the results and to dictate which rows to include in TOP. In this case, TOP always wins (though depending on the index chosen to scan the data, you might observe that your order is working as expected - but this is just a coincidence).

In order to accomplish what you want, you need to add your ORDER BY clause to the queries that pull data from the view, not to the code of the view itself.

So your view code should just be:

CREATE VIEW [dbo].[TopUsersTest] 
AS 
  SELECT 
    u.[DisplayName], SUM(a.AnswerMark) AS Marks
  FROM
    dbo.Users_Questions AS uq
    INNER JOIN [dbo].[Users] AS u
      ON u.[UserID] = us.[UserID] 
    INNER JOIN [dbo].[Answers] AS a
      ON a.[AnswerID] = uq.[AnswerID]
    GROUP BY u.[DisplayName];

The ORDER BY is meaningless so should not even be included.

To illustrate, using AdventureWorks2012, here is an example:

CREATE VIEW dbo.SillyView
AS
  SELECT TOP 100 PERCENT 
    SalesOrderID, OrderDate, CustomerID , AccountNumber, TotalDue
  FROM Sales.SalesOrderHeader
  ORDER BY CustomerID;
GO

SELECT SalesOrderID, OrderDate, CustomerID, AccountNumber, TotalDue
FROM dbo.SillyView;

Results:

SalesOrderID   OrderDate   CustomerID   AccountNumber   TotalDue
------------   ----------  ----------   --------------  ----------
43659          2005-07-01  29825        10-4020-000676  23153.2339
43660          2005-07-01  29672        10-4020-000117  1457.3288
43661          2005-07-01  29734        10-4020-000442  36865.8012
43662          2005-07-01  29994        10-4020-000227  32474.9324
43663          2005-07-01  29565        10-4020-000510  472.3108

And you can see from the execution plan that the TOP and ORDER BY have been absolutely ignored and optimized away by SQL Server:

There is no TOP operator at all, and no sort. SQL Server has optimized them away completely.

Now, if you change the view to say ORDER BY SalesID, you will then just happen to get the ordering that the view states, but only - as mentioned before - by coincidence.

But if you change your outer query to perform the ORDER BY you wanted:

SELECT SalesOrderID, OrderDate, CustomerID, AccountNumber, TotalDue
FROM dbo.SillyView
ORDER BY CustomerID;

You get the results ordered the way you want:

SalesOrderID   OrderDate   CustomerID   AccountNumber   TotalDue
------------   ----------  ----------   --------------  ----------
43793          2005-07-22  11000        10-4030-011000  3756.989
51522          2007-07-22  11000        10-4030-011000  2587.8769
57418          2007-11-04  11000        10-4030-011000  2770.2682
51493          2007-07-20  11001        10-4030-011001  2674.0227
43767          2005-07-18  11001        10-4030-011001  3729.364

And the plan still has optimized away the TOP/ORDER BY in the view, but a sort is added (at no small cost, mind you) to present the results ordered by CustomerID:

So, moral of the story, do not put ORDER BY in views. Put ORDER BY in the queries that reference them. And if the sorting is expensive, you might consider adding/changing an index to support it.

This works for all cases.

function resizeImg(imgId) {
    var img = document.getElementById(imgId);
    var $img = $(img);
    var maxWidth = 110;
    var maxHeight = 100;
    var width = img.width;
    var height = img.height;
    var aspectW = width / maxWidth;
    var aspectH = height / maxHeight;

    if (aspectW > 1 || aspectH > 1) {
        if (aspectW > aspectH) {
            $img.width(maxWidth);
            $img.height(height / aspectW);
        }
        else {
            $img.height(maxHeight);
            $img.width(width / aspectH);
        }
    }
}

I just wanted to share my experience with you if someone might has the same problem with MOODLE.

Our moodle platform was suddenly very slowly, the dashboard took about 2-3 times longer to load (up to 6 seconds) then usual and from time to time some pages didn't get loaded at all (not a 404 error but a blank page). In the Developer Tools Console the following error was visible: net::ERR_INCOMPLETE_CHUNKED_ENCODING.

Searching for this error, it looks like Chrome is the issue, but we had the problem with various browsers. After hours of research and comparing the databases from the days before I finally found the problem, someone turned the Event Monitoring on. However, in the "Config changes" log, this change wasn't visible! Turning Event Monitoring off, finally solved the problem - we had no rules defined for event monitoring.

We're running Moodle 3.1.2+ with MariaDB and PHP 5.4.

add an attribute to the EditText like android:imeOptions="actionSearch"

this is the best way to do the function

and the imeOptions also have some other values like "go" ?"next"?"done" etc.

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

Here is a very simple answer to this(only one line).

You can do that after you added the 'n' column into your df as follows.

import pandas as pd
df = pd.DataFrame({'l':['a','b','c','d'], 'v':[1,2,1,2]})
df['n'] = 0

df
    l   v   n
0   a   1   0
1   b   2   0
2   c   1   0
3   d   2   0

# here you can add the below code and it should work.
df = df[list('nlv')]
df

    n   l   v
0   0   a   1
1   0   b   2

However, if you have words in your columns names instead of letters. It should include two brackets around your column names. 

import pandas as pd
df = pd.DataFrame({'Upper':['a','b','c','d'], 'Lower':[1,2,1,2]})
df['Net'] = 0
df['Mid'] = 2
df['Zsore'] = 2

df

    Upper   Lower   Net Mid Zsore
0   a       1       0   2   2
1   b       2       0   2   2
2   c       1       0   2   2
3   d       2       0   2   2

# here you can add below line and it should work 
df = df[list(('Mid','Upper', 'Lower', 'Net','Zsore'))]
df

   Mid  Upper   Lower   Net Zsore
0   2   a       1       0   2
1   2   b       2       0   2
2   2   c       1       0   2
3   2   d       2       0   2

use pgAdmin or use pg_proc to get the source of your stored procedures. pgAdmin does the same.

The quick and dirty way, you can view the available environment variables from the below link.

Just replace localhost with your Jenkins hostname, if its different

base64 encoding takes 8-bit binary byte data and encodes it uses only the characters A-Z, a-z, 0-9, +, /* so it can be transmitted over channels that do not preserve all 8-bits of data, such as email.

Hence, it wants a string of 8-bit bytes. You create those in Python 3 with the b'' syntax.

If you remove the b, it becomes a string. A string is a sequence of Unicode characters. base64 has no idea what to do with Unicode data, it's not 8-bit. It's not really any bits, in fact. :-)

In your second example:

>>> encoded = base64.b64encode('data to be encoded')

All the characters fit neatly into the ASCII character set, and base64 encoding is therefore actually a bit pointless. You can convert it to ascii instead, with

>>> encoded = 'data to be encoded'.encode('ascii')

Or simpler:

>>> encoded = b'data to be encoded'

Which would be the same thing in this case.

* Most base64 flavours may also include a = at the end as padding. In addition, some base64 variants may use characters other than + and /. See the Variants summary table at Wikipedia for an overview.

Here you go:

SELECT Field1, COUNT(Field1)
  FROM Table1 
 GROUP BY Field1
HAVING COUNT(Field1) > 1
ORDER BY Field1 desc

In System.Diagnostics,

Debug.Write()
Debug.WriteLine()

etc. will print to the Output window in VS.

During a job interview of mine, the company CTO who was interviewing me tried out a word/web game I wrote in Java. Out of a word list of the entire Oxford English dictionary, what was the first word that came up to be guessed?

Of course, the most foul word in the English language.

Somehow, I still got the job offer, but I then tracked down a profanity word list (not unlike this one) and wrote a quick script to generate a new dictionary without all of the bad words (without even having to look at the list).

For your particular case, I think comparing the search to real words sounds like the way to go with a word list like that. The alternative styles/punctuation require a bit more work, but I doubt users will use that often enough to be an issue.

You can use WMI to figure this out. The Win32_BootConfiguration class will tell you both the logical drive and the physical device from which Windows boots. Specifically, the Caption property will tell you which device you're booting from.

For example, in powershell, just type gwmi Win32_BootConfiguration to get your answer.

grep -l 

(That's a lowercase L)

Your first usage of Map is inside a function in the combat class. That happens before Map is defined, hence the error.

A forward declaration only says that a particular class will be defined later, so it's ok to reference it or have pointers to objects, etc. However a forward declaration does not say what members a class has, so as far as the compiler is concerned you can't use any of them until Map is fully declared.

The solution is to follow the C++ pattern of the class declaration in a .h file and the function bodies in a .cpp. That way all the declarations appear before the first definitions, and the compiler knows what it's working with.

Wes McKinney (pandas' author) in Python for Data Analysis provides the following recipe:

groups = dict(list(gb))

which returns a dictionary whose keys are your group labels and whose values are DataFrames, i.e.

groups['foo']

will yield what you are looking for:

     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

To clarify the last post:

The VBoxManage command is:

VBoxManage setextradata <VM_NAME> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SHARE_NAME> 1

If you are very new to Android like I am this can be a little tricky. Make sure you call:

TextView myTextView = (TextView) findViewById(R.id.textView);
Typeface typeface=Typeface.createFromAsset(getAssets(), "fonts/your font.ttf");
myTextView.setTypeface(typeface);

method within a method such as onCreate.

A php/ajax progress bar can be done. (Checkout the Html_Ajax library in pear). However this requires installing a custom module into php.

Other methods require using an iframe, through which php looks to see how much of the file has been uploaded. However this hidden iframe, may be blocked by some browsers addons because hidden iframes are often used to send malicious data to a users computer.

Your best bet is to use some form of flash progress bar if you do not have control over your server.

UPDATE 2018-10-21:

As of this week, getRootDir() was deprecated. Please use getProjectDir() instead, as suggested in the comment section by Muzaraf Ali.

—-

Use this:

$this->get('kernel')->getRootDir();

And if you want the web root:

$this->get('kernel')->getRootDir() . '/../web' . $this->getRequest()->getBasePath();

this will work from controller action method...

EDIT: As for the services, I think the way you did it is as clean as possible, although I would pass complete kernel service as an argument... but this will also do the trick...

Keeping it simple, I personally like string concatenation:

print("Total score for " + name + " is " + score)

It works with both Python 2.7 an 3.X.

NOTE: If score is an int, then, you should convert it to str:

print("Total score for " + name + " is " + str(score))

In case that you have Ubuntu in your machine, the following steps will help you:

1. Check first in your php testing file if you have soap (client / server)or not by using phpinfo(); and check results in the browser. In case that you have it, it will seems like the following image ( If not go to step 2 ):

2. Open your terminal and paste: sudo apt-get install php-soap.

3. Restart your apache2 server in terminal : service apache2 restart.

4. To check use your php test file again to be seems like mine in step 1.

This is how I did it. You can try

    public class ABCService {
    @Resource(name="ABCDao")
    ABCDao abcDao;

    public int addNewABC(ABC abc) {
         ABC.setId(0);
         return abcDao.insertABC(abc);
    }
}

I am adding it so that someone in a similar situation might find it helpful.

So, even after multiDexEnabled = true I was getting the same error. I had no duplicate libraries. None of the above solutions worked. Upon reading the error log, I found OutOfMemError issue to be the primary reason and thought of changing the heap size somehow. Hence, this -

dexOptions {
        preDexLibraries = false
        javaMaxHeapSize "4g"
    }

Where "4g" means HeapSize of 4 GB. And it worked! I hope it does for you too.

You can use 100vw / 100vh. CSS3 gives us viewport-relative units. 100vw means 100% of the viewport width. 100vh; 100% of the height.

    <div style="display:flex; justify-content: space-between;background-color: lightyellow; width:100%; height:85vh">
        <div style="width:70%; height: 100%; border: 2px dashed red"></div>
        <div style="width:30%; height: 100%; border: 2px dashed red"></div>
    </div>

Assign after the EXEC token:

DECLARE @returnValue INT

EXEC @returnValue = SP_One
