I encountered the same problem on windows 10. My very specific issue is due to my installation of Anaconda. I installed Anaconda and under the path Path/to/Anaconda3/, there comes the python.exe. Thus, I didn't install python at all because Anaconda includes python. When using pip to install packages, I found the same error report, pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available..

The solution was the following:

1) you can download python again on the official website;

2) Navigate to the directory where "Python 3.7 (64-bit).lnk"is located

3) import ssl and exit()

4) type in cmd, "Python 3.7 (64-bit).lnk" -m pip install tensorflow for instance.

Here, you're all set.

There's now a much easier way to install an older version of a formula that you'd previously installed. Simply use

brew switch [formula] [version]

For instance, I alternate regularly between Node.js 0.4.12 and 0.6.5:

brew switch node 0.4.12
brew switch node 0.6.5

Since brew switch just changes the symlinks, it's very fast. See further documentation on the Homebrew Wiki under External Commands.

I had exactly the same error, but I installed postgreSQL through brew and re-run the original command and it worked perfectly :

brew install postgresql

Those won't necessarily give the same result: find() will get you any descendant node, whereas children() will only get you immediate children that match.

At one point, find() was a lot slower since it had to search for every descendant node that could be a match, and not just immediate children. However, this is no longer true; find() is much quicker due to using native browser methods.

Kotlin static and constant value & method declare

object MyConstant {

@JvmField   // for access in java code 
val PI: Double = 3.14

@JvmStatic // JvmStatic annotation for access in java code
fun sumValue(v1: Int, v2: Int): Int {
    return v1 + v2
}

}

Access value anywhere

val value = MyConstant.PI
val value = MyConstant.sumValue(10,5)

Older versions of git require you first define an ignore pattern and immediately (on the next line) define the exclusion. [tested on version 1.9.3 (Apple Git-50)]

/config.php
!/*/config.php

Later versions only require the following [tested on version 2.2.1]

/config.php

Sometimes using the error event is not feasible, e.g. because you're trying to do something on a page that’s already loaded, such as when you’re running code via the console, a bookmarklet, or a script loaded asynchronously. In that case, checking that img.naturalWidth and img.naturalHeight are 0 seems to do the trick.

For example, here's a snippet to reload all broken images from the console:

$$("img").forEach(img => {
  if (!img.naturalWidth && !img.naturalHeight) {
    img.src = img.src;
  }
}

I had a similar issue. I needed to keep the legacy encrypted passwords (Base64/SHA-1/Random salt Encoded) as users will not want to change their passwords or re-register. However I wanted to use the BCrypt encoder moving forward too.

My solution was to write a bespoke decoder that checks to see which encryption method was used first before matching (BCrypted ones start with $).

To get around the salt issue, I pass into the decoder a concatenated String of salt + encrypted password via my modified user object.

Decoder

@Component
public class LegacyEncoder implements PasswordEncoder {

    private static final String BCRYP_TYPE = "$";
    private static final PasswordEncoder BCRYPT = new BCryptPasswordEncoder();

    @Override
    public String encode(CharSequence rawPassword) {

    return BCRYPT.encode(rawPassword);
    }

    @Override
    public boolean matches(CharSequence rawPassword, String encodedPassword) {

    if (encodedPassword.startsWith(BCRYP_TYPE)) {
        return BCRYPT.matches(rawPassword, encodedPassword);
    }

    return sha1SaltMatch(rawPassword, encodedPassword);
    }

    @SneakyThrows
    private boolean sha1SaltMatch(CharSequence rawPassword, String encodedPassword) {

    String[] saltHash = encodedPassword.split(User.SPLIT_CHAR);

    // Legacy code from old system   
    byte[] b64salt = Base64.getDecoder().decode(saltHash[0].getBytes());
    byte[] validHash = Base64.getDecoder().decode(saltHash[1]);
    byte[] checkHash = Utility.getHash(5, rawPassword.toString(), b64salt);

    return Arrays.equals(checkHash, validHash);
    }

}

User Object

public class User implements UserDetails {

    public static final String SPLIT_CHAR = ":";

    @Id
    @Column(name = "user_id", nullable = false)
    private Integer userId;

    @Column(nullable = false, length = 60)
    private String password;

    @Column(nullable = true, length = 32)
    private String salt;

.
.

    @PostLoad
    private void init() {

    username = emailAddress; //To comply with UserDetails
    password = salt == null ? password : salt + SPLIT_CHAR + password;
    }        

You can also add a hook to re-encode the password in the new BCrypt format and replace it. Thus phasing out the old method.

I encountered the same issue when trying to use Cordova. Turns out I already had brew, try which brew, but it was outdated. So, I had to update it first:

1. Update brew: brew update
2. Install Apache Ant: brew install ant

Apparently this issue caused by Android Studio on the various situation but the reason is build error When importing an existing project into android studio.

In my case, I've imported my exist project where I was supposed to install few build tools then finally build configuration was done with error. In this case, just do the following things

1. Close the current project
2. File>New>Import Project (Don't use the open recent project)
   
   Note: I'm sure this kind of error is not on source code when this happened on Import project.

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

C++11

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

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

C++14

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

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

WHERE t.date >= DATE_ADD(CURDATE(), INTERVAL '-3' DAY);

use quotes on the -3 value

Item[] newItemList = new  Item[itemList.length+1];
    //for loop to go thorough the list one by one
    for(int i=0; i< itemList.length;i++){
        //value is stored here in the new list from the old one
        newItemList[i]=itemList[i];
    }
    //all the values of the itemLists are stored in a bigger array named newItemList
    itemList=newItemList;

If you know which column # it is (first / second / nth) then this solution posted on a similar question works regardless of whether it is named or unnamed, and in one line: https://stackoverflow.com/a/26336314/4355695

df.rename(columns = {list(df)[1]:'new_name'}, inplace=True)
# 1 is for second column (0,1,2..)

I am trying to set a JPanel's background using an image, however, every example I find seems to suggest extending the panel with its own class

yes you will have to extend JPanel and override the paintcomponent(Graphics g) function to do so.

@Override
  protected void paintComponent(Graphics g) {

    super.paintComponent(g);
        g.drawImage(bgImage, 0, 0, null);
}

I have been looking for a way to simply add the image without creating a whole new class and within the same method (trying to keep things organized and simple).

You can use other component which allows to add image as icon directly e.g. JLabel if you want.

ImageIcon icon = new ImageIcon(imgURL); 
JLabel thumb = new JLabel();
thumb.setIcon(icon);

But again in the bracket trying to keep things organized and simple !! what makes you to think that just creating a new class will lead you to a messy world ?

• Right click the Google Chrome icon and select Properties.
• Copy the value of Target, for example: "C:\Users\zero\AppData\Local\Google\Chrome\Application\chrome.exe".
• Create a shortcut on your Desktop.

• Paste the value into Location of the item, and append --kiosk <your url>:

  "C:\Users\zero\AppData\Local\Google\Chrome\Application\chrome.exe" --kiosk http://www.google.com
  

• Press Apply, then OK.

• To start Chrome at Windows startup, copy this shortcut and paste it into the Startup folder (Start -> Program -> Startup).

To see just the Python releases, do conda search --full-name python.

egrep -ir --include=*.{php,html,js} "(document.cookie|setcookie)" .

The r flag means to search recursively (search subdirectories). The i flag means case insensitive.

If you just want file names add the l (lowercase L) flag:

egrep -lir --include=*.{php,html,js} "(document.cookie|setcookie)" .

code example below:

g.setFont(new Font("TimesRoman", Font.PLAIN, 30));
g.drawString("Welcome to the Java Applet", 20 , 20);

When you want to put your Servlet file in your custom location or with custom name, rather than the default naming convention [servletname]-servlet.xml and path under Web-INF/ ,then you can use ContextLoaderListener.

You are getting close!

# Find all of the text between paragraph tags and strip out the html
page = soup.find('p').getText()

Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like

soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})

to zero in on the body of the article.

Probably the mymobileNO.titleLabel.text value doesn't include the scheme tel://

Your code should look like this:

NSString *phoneNumber = [@"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

Here is a complete solution based on the LocationManager and as fallbacks the TelephonyManager and the Network Provider's locations. I used the above answer from @Marco W. for the fallback part(great answer as itself!).

Note: the code contains PreferencesManager, this is a helper class that saves and loads data from SharedPrefrences. I'm using it to save the country to S"P, I'm only getting the country if it is empty. For my product I don't really care for all the edge cases(user travels abroad and so on).

public static String getCountry(Context context) {
    String country = PreferencesManager.getInstance(context).getString(COUNTRY);
    if (country != null) {

        if (location == null) {
            log.w("Couldn't get location from network and gps providers")
            return

        try {

                    PreferencesManager.getInstance(context).putString(COUNTRY, country);
                    return country;
                }
            }

typedef enum state {DEAD,ALIVE} State;
|     | |                     | |   |^ terminating semicolon, required! 
|     | |   type specifier    | |   |
|     | |                     | ^^^^^  declarator (simple name)

|     | ^^^^^^^^^^^^^^^^^^^^^^^  
|     |
^^^^^^^-- storage class specifier (in this case typedef)

The typedef keyword is a pseudo-storage-class specifier. Syntactically, it is used in the same place where a storage class specifier like extern or static is used. It doesn't have anything to do with storage. It means that the declaration doesn't introduce the existence of named objects, but rather, it introduces names which are type aliases.

After the above declaration, the State identifier becomes an alias for the type enum state {DEAD,ALIVE}. The declaration also provides that type itself. However that isn't typedef doing it. Any declaration in which enum state {DEAD,ALIVE} appears as a type specifier introduces that type into the scope:

enum state {DEAD, ALIVE} stateVariable;

If enum state has previously been introduced the typedef has to be written like this:

typedef enum state State;

otherwise the enum is being redefined, which is an error.

Like other declarations (except function parameter declarations), the typedef declaration can have multiple declarators, separated by a comma. Moreover, they can be derived declarators, not only simple names:

typedef unsigned long ulong, *ulongptr;
|     | |           | |  1 | |   2   |
|     | |           | |    | ^^^^^^^^^--- "pointer to" declarator
|     | |           | ^^^^^^------------- simple declarator
|     | ^^^^^^^^^^^^^-------------------- specifier-qualifier list
^^^^^^^---------------------------------- storage class specifier

This typedef introduces two type names ulong and ulongptr, based on the unsigned long type given in the specifier-qualifier list. ulong is just a straight alias for that type. ulongptr is declared as a pointer to unsigned long, thanks to the * syntax, which in this role is a kind of type construction operator which deliberately mimics the unary * for pointer dereferencing used in expressions. In other words ulongptr is an alias for the "pointer to unsigned long" type.

Alias means that ulongptr is not a distinct type from unsigned long *. This is valid code, requiring no diagnostic:

unsigned long *p = 0;
ulongptr q = p;

The variables q and p have exactly the same type.

The aliasing of typedef isn't textual. For instance if user_id_t is a typedef name for the type int, we may not simply do this:

unsigned user_id_t uid;  // error! programmer hoped for "unsigned int uid". 

This is an invalid type specifier list, combining unsigned with a typedef name. The above can be done using the C preprocessor:

#define user_id_t int
unsigned user_id_t uid;

whereby user_id_t is macro-expanded to the token int prior to syntax analysis and translation. While this may seem like an advantage, it is a false one; avoid this in new programs.

Among the disadvantages that it doesn't work well for derived types:

 #define silly_macro int *

 silly_macro not, what, you, think;

This declaration doesn't declare what, you and think as being of type "pointer to int" because the macro-expansion is:

 int * not, what, you, think;

The type specifier is int, and the declarators are *not, what, you and think. So not has the expected pointer type, but the remaining identifiers do not.

And that's probably 99% of everything about typedef and type aliasing in C.

There re many ways to drop a database or update existing database, simply you can switched to previous migrations.

dotnet ef database update previousMigraionName    

But some databases have limitations like not allow to modify after create relationships, means you have not allow privileges to drop columns from ef core database providers but most of time in ef core drop database is allowed.so you can drop DB using drop command and then you use previous migration again.

dotnet ef database drop
PMC command 
PM> drop-database

OR you can do manually deleting database and do a migration.

Sparky's answer is one standard way to solve this problem, but as I also wrote in my comment, you run the risk of overflows. This can be solved by using a wider type, but what if you want to divide long longs?

Nathan Ernst's answer provides one solution, but it involves a function call, a variable declaration and a conditional, which makes it no shorter than the OPs code and probably even slower, because it is harder to optimize.

My solution is this:

q = (x % y) ? x / y + 1 : x / y;

It will be slightly faster than the OPs code, because the modulo and the division is performed using the same instruction on the processor, because the compiler can see that they are equivalent. At least gcc 4.4.1 performs this optimization with -O2 flag on x86.

In theory the compiler might inline the function call in Nathan Ernst's code and emit the same thing, but gcc didn't do that when I tested it. This might be because it would tie the compiled code to a single version of the standard library.

As a final note, none of this matters on a modern machine, except if you are in an extremely tight loop and all your data is in registers or the L1-cache. Otherwise all of these solutions will be equally fast, except for possibly Nathan Ernst's, which might be significantly slower if the function has to be fetched from main memory.

One better way would be to use SELECT COUNT statement of SQL.

Just when you need the count of number of rows returned, execute another query returning the exact number of result of that query.

 try
{
   Conn=ConnectionODBC.getConnection();
   Statement stmt = Conn.createStatement();        
    String sqlStmt = sql;        
    String sqlrow = SELECT COUNT(*) from (sql) rowquery;
    String total = stmt.executeQuery(sqlrow);
    int rowcount = total.getInt(1);
    }

If this is for Cygwin, it installs "pip" as "pip2". Just create a softlink to "pip2" in the same location where "pip2" is installed.

I had the same problem, and it came from a wrong client_id / Facebook App ID.

Did you switch your Facebook app to "public" or "online ? When you do so, Facebook creates a new app with a new App ID.

You can compare the "client_id" parameter value in the url with the one in your Facebook dashboard.

Also Make sure your app is public. Click on + Add product Now go to products => Facebook Login Now do the following:

Valid OAuth redirect URIs : example.com/

Once you are able to parse those strings into a Date object comparing them is easy (Using the < operator). Parsing the dates will depend on the format. You may take a look at Datejs which might simplify this task.

you can use below event of keypress on document load.

 $(document).keypress(function(e) {
            if(e.which == 13) {
               yourfunction();
            }
        });

Thanks

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

In your app's build.gradle add the following:

android {
    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'

}

Enforces Gradle to only compile the version number you state for all dependencies, no matter which version number the dependencies have stated.

If you’re running JQuery on a production site, which library should you load? JQuery.js or JQuery.min.js? The short answer is, they are essentially the same, with the same functionality.

One version is long, while the other is the minified version. The minified is compressed to save space and page load time. White spaces have been removed in the minified version making them jibberish and impossible to read.

If you’re going to run the JQuery library on a production site, I recommend that you use the minified version, to decrease page load time, which Google now considers in their page ranking.

Another good option is to use Google’s online javascript library. This will save you the hassle of downloading the library, as well as uploading to your site. In addition, your site also does not use resources when JQuery is loaded.

The latest JQuery minified version from Google is available here.

You can link to it in your pages using:

Add target="_blank" to the <form> tag.

For those looking for an example of how to pass the OAuth2 authorization (access token) in the header (as opposed to using a request or body parameter), here is how it's done:

Authorization: Bearer 0b79bab50daca910b000d4f1a2b675d604257e42

Here is new may to authenticate from "admin" and then switch to your desired DB for further operations:

   var MongoClient = require('mongodb').MongoClient;
var Db = require('mongodb').Db, Server = require('mongodb').Server ,
    assert = require('assert');

var user = 'user';
var password = 'password';

MongoClient.connect('mongodb://'+user+':'+password+'@localhost:27017/opsdb',{native_parser:true, authSource:'admin'}, function(err,db){
    if(err){
        console.log("Auth Failed");
        return;
    }
    console.log("Connected");
    db.collection("cols").find({loc:{ $eq: null } }, function(err, docs) {
        docs.each(function(err, doc) {
          if(doc) {
            console.log(doc['_id']);
          }
        });
    });

    db.close();

}); 

There is NNCron for Windows. IT can schedule jobs to be run periodically.

An Observable is an object that emits a stream of events: Next, Error and Completed.

When your function returns an Observable, it is not returning a stream, but an instance of Observable. The flatMap operator simply maps that instance to a stream.

That is the behaviour of flatMap when compared to map: Execute the given function and flatten the resulting object into a stream.

You have to download and add the SQLite JDBC driver to your classpath.
You can download from here https://bitbucket.org/xerial/sqlite-jdbc/downloads

If you use Gradle, you will only have to add the SQLite dependency:

dependencies {
    compile 'org.xerial:sqlite-jdbc:3.8.11.2'
} 

Next thing you have to do is to initialize the driver:

try {
    Class.forName("org.sqlite.JDBC");
} catch (ClassNotFoundException eString) {
    System.err.println("Could not init JDBC driver - driver not found");
}

You can install pywin32 wheel packages from PYPI with PIP by pointing to this package: https://pypi.python.org/pypi/pypiwin32 No need to worry about first downloading the package, just use pip:

pip install pypiwin32

Currently I think this is "the easiest" way to get in working :) Hope this helps.

All you need to do is use size() to get the last value of the Arraylist. For ex. if you ArrayList of integers, then to get last value you will have to

int lastValue = arrList.get(arrList.size()-1);

Remember, elements in an Arraylist can be accessed using index values. Therefore, ArrayLists are generally used to search items.

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

Use org.apache.commons.lang3.StringUtils

String emptyString = new String();    
result = StringUtils.defaultIfEmpty(emptyString, "default");
System.out.println(result);

String nullString = null;
result = StringUtils.defaultIfEmpty(nullString, "default");
System.out.println(result);

Both of the above options will print:

default

default

All compilers I know will replace a simple std::copy with a memcpy when it is appropriate, or even better, vectorize the copy so that it would be even faster than a memcpy.

In any case: profile and find out yourself. Different compilers will do different things, and it's quite possible it won't do exactly what you ask.

See this presentation on compiler optimisations (pdf).

Here's what GCC does for a simple std::copy of a POD type.

#include <algorithm>

struct foo
{
  int x, y;    
};

void bar(foo* a, foo* b, size_t n)
{
  std::copy(a, a + n, b);
}

Here's the disassembly (with only -O optimisation), showing the call to memmove:

bar(foo*, foo*, unsigned long):
    salq    $3, %rdx
    sarq    $3, %rdx
    testq   %rdx, %rdx
    je  .L5
    subq    $8, %rsp
    movq    %rsi, %rax
    salq    $3, %rdx
    movq    %rdi, %rsi
    movq    %rax, %rdi
    call    memmove
    addq    $8, %rsp
.L5:
    rep
    ret

If you change the function signature to

void bar(foo* __restrict a, foo* __restrict b, size_t n)

then the memmove becomes a memcpy for a slight performance improvement. Note that memcpy itself will be heavily vectorised.

If you using PHP 5.2, json_encode just expect only 1 parameter when call it. This is an alternative to unescape slash of json values:

stripslashes(json_encode($array))

Don't use it if your data is complicated.

There is really quite a number of ways to do this and all of the above are in one way or another valid approaches... Let me add a straightforward proposition. So assuming your current existing json file looks is this....

{
     "name":"myname"
}

And you want to bring in this new json content (adding key "id")

{
     "id": "134",
     "name": "myname"
 }

My approach has always been to keep the code extremely readable with easily traceable logic. So first, we read the entire existing json file into memory, assuming you are very well aware of your json's existing key(s).

import json 

# first, get the absolute path to json file
PATH_TO_JSON = 'data.json' #  assuming same directory (but you can work your magic here with os.)

# read existing json to memory. you do this to preserve whatever existing data. 
with open(PATH_TO_JSON,'r') as jsonfile:
    json_content = json.load(jsonfile) # this is now in memory! you can use it outside 'open'

Next, we use the 'with open()' syntax again, with the 'w' option. 'w' is a write mode which lets us edit and write new information to the file. Here s the catch that works for us ::: any existing json with the same target write name will be erased automatically.

So what we can do now, is simply write to the same filename with the new data

# add the id key-value pair (rmbr that it already has the "name" key value)
json_content["id"] = "134"

with open(PATH_TO_JSON,'w') as jsonfile:
    json.dump(json_content, jsonfile, indent=4) # you decide the indentation level

And there you go! data.json should be good to go for an good old POST request

to change multiple files (and saving a backup as *.bak):

perl -p -i -e "s/\|/x/g" *

will take all files in directory and replace | with x called a “Perl pie” (easy as a pie)

Enclosed in {} represents an object; enclosed in [] represents an array, there can be multiple objects in the array
example object :

{
    "brand": "bwm", 
    "price": 30000
}


{
    "brand": "benz", 
    "price": 50000
}

example array:

[
    {
        "brand": "bwm", 
        "price": 30000
    }, 
    {
        "brand": "benz", 
        "price": 50000
    }
]

In order to use JSON more beautifully, you can go here JSON Viewer do format

//By : Dhaval Nimavat
    import UIKit

   func weather_diff(country1:String,temp1:Double,country2:String,temp2:Double)->(c1:String,c2:String,diff:Double)
   {
    let c1 = country1
    let c2 = country2
    let diff = temp1 - temp2
    return(c1,c2,diff)
   }

   let result = 
   weather_diff(country1: "India", temp1: 45.5, country2: "Canada", temp2:    18.5)
   print("Weather difference between \(result.c1) and \(result.c2) is \(result.diff)")

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

Both functions are wrong. First of all function initNode has a confusing name. It should be named as for example initList and should not do the task of addNode. That is, it should not add a value to the list.

In fact, there is not any sense in function initNode, because the initialization of the list can be done when the head is defined:

Node *head = nullptr;

or

Node *head = NULL;

So you can exclude function initNode from your design of the list.

Also in your code there is no need to specify the elaborated type name for the structure Node that is to specify keyword struct before name Node.

Function addNode shall change the original value of head. In your function realization you change only the copy of head passed as argument to the function.

The function could look as:

void addNode(Node **head, int n)
{
    Node *NewNode = new Node {n, *head};
    *head = NewNode;
}

Or if your compiler does not support the new syntax of initialization then you could write

void addNode(Node **head, int n)
{
    Node *NewNode = new Node;
    NewNode->x = n;
    NewNode->next = *head;
    *head = NewNode;
}

Or instead of using a pointer to pointer you could use a reference to pointer to Node. For example,

void addNode(Node * &head, int n)
{
    Node *NewNode = new Node {n, head};
    head = NewNode;
}

Or you could return an updated head from the function:

Node * addNode(Node *head, int n)
{
    Node *NewNode = new Node {n, head};
    head = NewNode;
    return head;
}

And in main write:

head = addNode(head, 5);

If you have this problem when using an instaled version, when using setup.py, make sure your module is included inside packages

setup(name='Your program',
    version='0.7.0',
    description='Your desccription',
    packages=['foo', 'foo.bar'], # add `foo.bar` here

If the repository is on GitHub, you can use the open source Android app Octodroid which displays the size of the repository by default.

Works perfectly fine if the first option's value is null. Explanation : The HTML5 will read a null value on button submit. If not null (value attribute), the selected value is assumed not to be null hence the validation would have worked i.e by checking if there's been data in the option tag. Therefore it will not produce the validation method. However, i guess the other side becomes clear, if the value attribute is set to null ie (value = "" ), HTML5 will detect an empty value on the first or rather the default selected option thus giving out the validation message. Thanks for asking. Happy to help. Glad to know if i did.

I had the same problem on my mac, but in my case, the problem was that I did not run the database (sudo mongod) before; the problem was solved when I first ran the mondo sudod on the console and, once it was done, on another console, the connection to the server ...

I think you should install API 18 from android sdk if not already installed, otherwise you can try "invalidate caches and restart" (Find: File->invalidate caches and restart).

Your question doesn't address what you want to put in the DIV tags, which is probably why you've received some incomplete/wrong answers. The truth is that you can, as Royi said, put DIV tags inside of your forms. You don't want to do this for labels, for instance, but if you have a form with a bunch of checkboxes that you want to lay out into three columns, then by all means, use DIV tags (or SPAN, HEADER, etc.) to accomplish the look and feel you're trying to achieve.

I can see libc error in the log.

Your code is fine. What you are seeing is a linker issue.

If you put your code in a single file like this:

#include <iostream>
#include <string>

using namespace std;

string trim(const string& str)
{
    size_t first = str.find_first_not_of(' ');
    if (string::npos == first)
    {
        return str;
    }
    size_t last = str.find_last_not_of(' ');
    return str.substr(first, (last - first + 1));
}

int main() {
    string s = "abc ";
    cout << trim(s);

}

then do g++ test.cc and run a.out, you will see it works.

You should check if the file that contains the trim function is included in the link stage of your compilation process.

Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.

I just tested (should have done that first), and something like ng-show="!a && b" worked as expected.

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

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

Link to Reference

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

I know this is an old question, but I am surprised that all answers ensure that the method exists and it is a function, when the OP does only want to check for existence. To know it is a function (as many have stated) you may use:

typeof myObj.prop2 === 'function'

But you may also use as a condition:

typeof myObj.prop2

Or even:

myObj.prop2

This is so because a function evaluates to true and undefined evaluates to false. So if you know that if the member exists it may only be a function, you can use:

if(myObj.prop2) {
  <we have prop2>
}

Or in an expression:

myObj.prop2 ? <exists computation> : <no prop2 computation>

It's just like you did. And I'll give you a small tip for these kind of silly things: just use the browser url box to try js syntax. for example, write this: javascript:alert("test"+5) and you have your answer. The problem in your code is probably that this element does not exist in your document... maybe it's inside a form or something. You can test this too by writing in the url: javascript:alert(document.horseThumb_5) to check where your mistake is.

VBA subs are no macros. A VBA sub can be a macro, but it is not a must.

The term "macro" is only used for recorded user actions. from these actions a code is generated and stored in a sub. This code is simple and do not provide powerful structures like loops, for example Do .. until, for .. next, while.. do, and others.

The more elegant way is, to design and write your own VBA code without using the macro features!

VBA is a object based and event oriented language. Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.

If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx.exe".

In VBA you have nothing like this, but you have a XLSM file wich is started by Excel. You can attach some code to the Workbook_Open event. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets.

It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.

In the object based model you have objects, that have events and methods. methods are action you can do with a object. events are things that can happen to an object. An objects can contain another objects, and so on. You can create new objects, like sheets or charts.

You can fix this problem by adding "$(ProjectDir)" (or wherever the stdafx.h is) to list of directories under Project->Properties->Configuration Properties->C/C++->General->Additional Include Directories.

(change) event bound to classical input change event.

https://developer.mozilla.org/en-US/docs/Web/Events/change

You can use (change) event even if you don't have a model at your input as

<input (change)="somethingChanged()">

(ngModelChange) is the @Output of ngModel directive. It fires when the model changes. You cannot use this event without ngModel directive.

https://github.com/angular/angular/blob/master/packages/forms/src/directives/ng_model.ts#L124

As you discover more in the source code, (ngModelChange) emits the new value.

https://github.com/angular/angular/blob/master/packages/forms/src/directives/ng_model.ts#L169

So it means you have ability of such usage:

<input (ngModelChange)="modelChanged($event)">

modelChanged(newObj) {
    // do something with new value
}

Basically, it seems like there is no big difference between two, but ngModel events gains the power when you use [ngValue].

  <select [(ngModel)]="data" (ngModelChange)="dataChanged($event)" name="data">
      <option *ngFor="let currentData of allData" [ngValue]="currentData">
          {{data.name}}
      </option>
  </select>

dataChanged(newObj) {
    // here comes the object as parameter
}

assume you try the same thing without "ngModel things"

<select (change)="changed($event)">
    <option *ngFor="let currentData of allData" [value]="currentData.id">
        {{data.name}}
    </option>
</select>

changed(e){
    // event comes as parameter, you'll have to find selectedData manually
    // by using e.target.data
}

If the list is sorted, you can use a binary search. If not, then there is no better way.

If you're doing this a lot, it would almost certainly be worth your while to sort the list the first time. Since you can't modify the classes, you would have to use a Comparator to do the sorting and searching.

After trying a few things, and coming across PyMySQL Github, this worked:

sudo pip install PyMySQL

And to import use:

import pymysql

You can try the expand option in Series.str.split('seperator', expand=True).
By default expand is False.

expand : bool, default False
Expand the splitted strings into separate columns.

• If True, return DataFrame/MultiIndex expanding dimensionality.
• If False, return Series/Index, containing lists of strings.

As you probably figured out, the issue is that you are trying to allocate one large contiguous block of memory, which does not work due to memory fragmentation. If I needed to do what you are doing I would do the following:

int sizeA = 10000,
    sizeB = 10000;
double sizeInMegabytes = (sizeA * sizeB * 8.0) / 1024.0 / 1024.0; //762 mb
double[][] randomNumbers = new double[sizeA][];
for (int i = 0; i < randomNumbers.Length; i++)
{
    randomNumbers[i] = new double[sizeB];
}

Then, to get a particular index you would use randomNumbers[i / sizeB][i % sizeB].

Another option if you always access the values in order might be to use the overloaded constructor to specify the seed. This way you would get a semi random number (like the DateTime.Now.Ticks) store it in a variable, then when ever you start going through the list you would create a new Random instance using the original seed:

private static int randSeed = (int)DateTime.Now.Ticks;  //Must stay the same unless you want to get different random numbers.
private static Random GetNewRandomIterator()
{
    return new Random(randSeed);
}

It is important to note that while the blog linked in Fredrik Mörk's answer indicates that the issue is usually due to a lack of address space it does not list a number of other issues, like the 2GB CLR object size limitation (mentioned in a comment from ShuggyCoUk on the same blog), glosses over memory fragmentation, and fails to mention the impact of page file size (and how it can be addressed with the use of the CreateFileMapping function).

The 2GB limitation means that randomNumbers must be less than 2GB. Since arrays are classes and have some overhead them selves this means an array of double will need to be smaller then 2^31. I am not sure how much smaller then 2^31 the Length would have to be, but Overhead of a .NET array? indicates 12 - 16 bytes.

Memory fragmentation is very similar to HDD fragmentation. You might have 2GB of address space, but as you create and destroy objects there will be gaps between the values. If these gaps are too small for your large object, and additional space can not be requested, then you will get the System.OutOfMemoryException. For example, if you create 2 million, 1024 byte objects, then you are using 1.9GB. If you delete every object where the address is not a multiple of 3 then you will be using .6GB of memory, but it will be spread out across the address space with 2024 byte open blocks in between. If you need to create an object which was .2GB you would not be able to do it because there is not a block large enough to fit it in and additional space cannot be obtained (assuming a 32 bit environment). Possible solutions to this issue are things like using smaller objects, reducing the amount of data you store in memory, or using a memory management algorithm to limit/prevent memory fragmentation. It should be noted that unless you are developing a large program which uses a large amount of memory this will not be an issue. Also, this issue can arise on 64 bit systems as windows is limited mostly by the page file size and the amount of RAM on the system.

Since most programs request working memory from the OS and do not request a file mapping, they will be limited by the system's RAM and page file size. As noted in the comment by Néstor Sánchez (Néstor Sánchez) on the blog, with managed code like C# you are stuck to the RAM/page file limitation and the address space of the operating system.

That was way longer then expected. Hopefully it helps someone. I posted it because I ran into the System.OutOfMemoryException running a x64 program on a system with 24GB of RAM even though my array was only holding 2GB of stuff.

If the string contains Unicode data (strictly speaking, non-BMP characters) the other methods that have been posted will corrupt it, because you cannot swap the order of high and low surrogate code units when reversing the string. (More information about this can be found on my blog.)

The following code sample will correctly reverse a string that contains non-BMP characters, e.g., "\U00010380\U00010381" (Ugaritic Letter Alpa, Ugaritic Letter Beta).

public static string Reverse(this string input)
{
    if (input == null)
        throw new ArgumentNullException("input");

    // allocate a buffer to hold the output
    char[] output = new char[input.Length];
    for (int outputIndex = 0, inputIndex = input.Length - 1; outputIndex < input.Length; outputIndex++, inputIndex--)
    {
        // check for surrogate pair
        if (input[inputIndex] >= 0xDC00 && input[inputIndex] <= 0xDFFF &&
            inputIndex > 0 && input[inputIndex - 1] >= 0xD800 && input[inputIndex - 1] <= 0xDBFF)
        {
            // preserve the order of the surrogate pair code units
            output[outputIndex + 1] = input[inputIndex];
            output[outputIndex] = input[inputIndex - 1];
            outputIndex++;
            inputIndex--;
        }
        else
        {
            output[outputIndex] = input[inputIndex];
        }
    }

    return new string(output);
}

Try the code below to prevent the default behaviour scrolling back to the top of the page

$(document).ready(function() {   
  $('.galleryicon').live("click", function(e) {  // the (e) represent the event
    $('#mainImage').hide();     
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");     
    var i = $('<img />').attr('src',this.href).load(function() {         
      $('#mainImage').attr('src', i.attr('src'));         
      $('#cakebox').css('background-image', 'none');         
      $('#mainImage').fadeIn();     
    });
  e.preventDefault(); //Prevent default click action which is causing the 
  return false;       //page to scroll back to the top
  });  
});

For more information on event.preventDefault() have a look here at the official documentation.

Find element with id in row using jquery

$(document).ready(function () {
$("button").click(function() {
    //find content of different elements inside a row.
    var nameTxt = $(this).closest('tr').find('.name').text();
    var emailTxt = $(this).closest('tr').find('.email').text();
    //assign above variables text1,text2 values to other elements.
    $("#name").val( nameTxt );
    $("#email").val( emailTxt );
    });
});

The general methodology would be to iterate through the ArrayList, and insert the values into the HashMap. An example is as follows:

HashMap<String, Product> productMap = new HashMap<String, Product>();
for (Product product : productList) {
   productMap.put(product.getProductCode(), product);
}

I never managed to make the '\t' metacharacter work with grep. However I found two alternate solutions:

1. Using <Ctrl-V> <TAB> (hitting Ctrl-V then typing tab)
2. Using awk: foo | awk '/\t/'

I didn't see anyone answer this correctly. So I'm posting it here. In order to get columns to show up you need to specify the following line.

lvRegAnimals.View = View.Details;

And then add your columns after that.

lvRegAnimals.Columns.Add("Id", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);

Hope this helps anyone else looking for this answer in the future.

I had similar issue and got solved by doing following ,

2) ANT_HOME as F:\ant\apache-ant-1.8.4-bin\apache-ant-1.8.4

3) add both to 'path ' in system variables

            fputs("Error reading file", stderr);
        } else {
            source[newLen++] = '\0'; /* Just to be safe. */
        }
    }
    fclose(fp);
}
     
int sourceLen = bufsize - 1;
int destLen = sourceLen/2;
unsigned char* dest = malloc(destLen);

I use this simpleton because we got our String class "special" (i.e. not standard):

void splitString(const String &s, const String &delim, std::vector<String> &result) {
    const int l = delim.length();
    int f = 0;
    int i = s.indexOf(delim,f);
    while (i>=0) {
        String token( i-f > 0 ? s.substring(f,i-f) : "");
        result.push_back(token);
        f=i+l;
        i = s.indexOf(delim,f);
    }
    String token = s.substring(f);
    result.push_back(token);
}

It the case of HashSet, it does NOT replace it.

From the docs:

http://docs.oracle.com/javase/6/docs/api/java/util/HashSet.html#add(E)

"Adds the specified element to this set if it is not already present. More formally, adds the specified element e to this set if this set contains no element e2 such that (e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returns false."

Instead of setting the value directly you can try using copy/paste, so instead of:

Worksheets(2).Cells(a, 15) = Worksheets(1).Cells(i, 3).Value

Try this:

Worksheets(1).Cells(i, 3).Copy
Worksheets(2).Cells(a, 15).PasteSpecial Paste:=xlPasteFormats
Worksheets(2).Cells(a, 15).PasteSpecial Paste:=xlPasteValues

To just set the font to bold you can keep your existing assignment and add this:

If Worksheets(1).Cells(i, 3).Font.Bold = True Then
  Worksheets(2).Cells(a, 15).Font.Bold = True
End If

You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.

You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig. It will give out some information and your local IP should look like 192.168.1.x.

Items should have an "ID" field, and Tags should have an "ID" field (Primary Key, Clustered).

Then make an intermediate table of ItemID/TagID and put the "Perfect Index" on there.

Using dynamic enums is bad no matter which way. You will have to go through the trouble of "duplicating" the data to ensure clear and easy code easy to maintain in the future.

If you start introducing automatic generated libraries, you are for sure causing more confusion to future developers having to upgrade your code than simply making your enum coded within the appropriate class object.

The other examples given sound nice and exciting, but think about the overhead on code maintenance versus what you get from it. Also, are those values going to change that frequently?

Here's what worked best for me.

SELECT *
FROM @T1
EXCEPT
SELECT a.*
FROM @T1 a
JOIN @T2 b ON a.ID = b.ID

This was more than twice as fast as any other method I tried.

No, POST/GET values are never null. The best they can be is an empty string, which you can convert to null/'NULL'.

if ($_POST['value'] === '') {
    $_POST['value'] = null; // or 'NULL' for SQL
}

This is also useful if you only want to temporarily suppress the warning:

import matplotlib.pyplot as plt
       
with plt.rc_context(rc={'figure.max_open_warning': 0}):
    lots_of_plots()

No need for "tricks". Python 3.3 comes with PyLauncher "py.exe", installs it in the path, and registers it as the ".py" extension handler. With it, a special comment at the top of a script tells the launcher which version of Python to run:

#!python2
print "hello"

Or

#!python3
print("hello")

From the command line:

py -3 hello.py

Or

py -2 hello.py

py hello.py by itself will choose the latest Python installed, or consult the PY_PYTHON environment variable, e.g. set PY_PYTHON=3.6.

See Python Launcher for Windows

HTTP Basic + HTTPS is one common method.

Because your delimiter is ", " you could use any of the following:

public class StringDelim {

    public static void removeBrackets(String string) {
        System.out.println(string.substring(1, string.length() - 1));
    }

    public static void main(String... args) {
        // Array.toString() example
        String [] arr = {"Hi" , "My", "name", "is", "br3nt"};
        String string = Arrays.toString(arr);
        removeBrackets(string);

        // List#toString() example
        List<String> list = new ArrayList<String>();
        list.add("Hi");
        list.add("My");
        list.add("name");
        list.add("is");
        list.add("br3nt");
        string = list.toString();
        removeBrackets(string);

        // Map#values().toString() example
        Map<String, String> map = new LinkedHashMap<String, String>();
        map.put("1", "Hi");
        map.put("2", "My");
        map.put("3", "name");
        map.put("4", "is");
        map.put("5", "br3nt");
        System.out.println(map.values().toString());
        removeBrackets(string);

        // Enum#toString() example
        EnumSet<Days> set = EnumSet.allOf(Days.class);
        string = set.toString();
        removeBrackets(string);
    }

    public enum Days {
        MON("Monday"),
        TUE("Tuesday"),
        WED("Wednesday"),
        THU("Thursday"),
        FRI("Friday"),
        SAT("Saturday"),
        SUN("Sunday");

        private final String day;

        Days(String day) {this.day = day;}
        public String toString() {return this.day;}
    }
}

If your delimiter is ANYTHING else then this isn't going to work for you.

If you want an index to be used and the query not to do a table scan:

WHERE timestamp >= CURDATE()
  AND timestamp < CURDATE() + INTERVAL 1 DAY

To show the difference that this makes on the actual execution plans, we'll test with an SQL-Fiddle (an extremely helpful site):

CREATE TABLE test                            --- simple table
    ( id INT NOT NULL AUTO_INCREMENT
    ,`timestamp` datetime                    --- index timestamp
    , data VARCHAR(100) NOT NULL 
          DEFAULT 'Sample data'
    , PRIMARY KEY (id)
    , INDEX t_IX (`timestamp`, id)
    ) ;

INSERT INTO test
    (`timestamp`)
VALUES
    ('2013-02-08 00:01:12'),
    ---                                      --- insert about 7k rows
    ('2013-02-08 20:01:12') ;

Lets try the 2 versions now.

Version 1 with DATE(timestamp) = ?

EXPLAIN
SELECT * FROM test 
WHERE DATE(timestamp) = CURDATE()            ---  using DATE(timestamp)
ORDER BY timestamp ;

Explain:

ID  SELECT_TYPE  TABLE  TYPE  POSSIBLE_KEYS  KEY  KEY_LEN  REF 
1   SIMPLE       test   ALL

ROWS  FILTERED  EXTRA
6671  100       Using where; Using filesort

It filters all (6671) rows and then does a filesort (that's not a problem as the returned rows are few)

Version 2 with timestamp <= ? AND timestamp < ?

EXPLAIN
SELECT * FROM test 
WHERE timestamp >= CURDATE()
  AND timestamp < CURDATE() + INTERVAL 1 DAY
ORDER BY timestamp ;

Explain:

ID  SELECT_TYPE  TABLE  TYPE  POSSIBLE_KEYS  KEY  KEY_LEN  REF 
1   SIMPLE       test   range t_IX           t_IX    9 

ROWS  FILTERED  EXTRA
2     100       Using where

It uses a range scan on the index, and then reads only the corresponding rows from the table.

I find this works easier. readonly the input field, then style it so the end user knows it's read only. inputs placed here (from AJAX for example) can still submit, without extra code.

<input readonly style="color: Grey; opacity: 1; ">

signal isn't the most reliable way as it differs in implementations. I would recommend using sigaction. Tom's code would now look like this :

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>

void my_handler(int s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{

   struct sigaction sigIntHandler;

   sigIntHandler.sa_handler = my_handler;
   sigemptyset(&sigIntHandler.sa_mask);
   sigIntHandler.sa_flags = 0;

   sigaction(SIGINT, &sigIntHandler, NULL);

   pause();

   return 0;    
}

REST stands for REpresentational State Transfer which is a resource based architectural style. Resource based means that data and functionalities are considered as resources.

OData is a web based protocol that defines a set of best practices for building and consuming RESTful web services. OData is a way to create RESTful web services thus an implementation of REST.

Just found another reason why an element goes blurry when being transformed. I was using transform: translate3d(-5.5px, -18px, 0); to re-position an element once it had been loaded in, however that element became blurry.

I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values. Whole numbers don't cause the blur, and the further away I went from the whole number the worse the blur became.

i.e. 5.5px blurs the element the most, 5.1px the least.

Just thought I'd chuck this here in case it helps anybody.

This is not possible with the magic methods, however you can achieve this using DQL (Doctrine Query Language). In your example, assuming you have entity named Orders with Product property, just go ahead and do the following:

$dql_query = $em->createQuery("
    SELECT o FROM AcmeCodeBundle:Orders o
    WHERE 
      o.OrderEmail = '[email protected]' AND
      o.Product LIKE 'My Products%'
");
$orders = $dql_query->getResult();

Should do exactly what you need.

I had the same issue. As pointed out by other answers ping and nslookup use different mechanisms to lookup an ip.

Chances are you are trying to ping a machine not on the same domain. When you ping the fully qualified name of the server this should then work.

nslookup works:

PS C:\Users\Administrator> nslookup nuget
Server:  ad-01.docs.com
Address:  192.168.10.20

Name:    nuget.docs.com
Address:  192.168.10.17

Ping fails:

PS C:\Users\Administrator> ping nuget
Ping request could not find host nuget. Please check the name and try again.

Ping works, using FQDN:

PS C:\Users\Administrator> ping nuget.docs.com

To fix this you will need to alter the DNS setting for the machine and add the DNS suffix to lookup.

1. Control Panel\Network and Internet\Network Connections
2. Network adapter -> properties
3. IPV4 -> Properties
4. General tab -> Advanced
5. DNS Tab
6. Select "Append these DNS suffixes (in order)"
7. Add the required domain names
8. Disable, then enable your network adapter (don't do this on a VM, you'll loose your connection, instead try 'ipconfig /renew')

Try assigning a value to $aug1 before use it in if[] statements; the error message will disappear afterwards.

For beginners: To create your .bash_profile file in your home directory on MacOS, run:

nano ~/.bash_profile

Then you can paste in the following:

https://gist.github.com/mocon/0baf15e62163a07cb957888559d1b054

As you can see, it includes some example aliases and an environment variable at the bottom.

One you're done making your changes, follow the instructions at the bottom of the Nano editor window to WriteOut (Ctrl-O) and Exit (Ctrl-X). Then quit your Terminal and reopen it, and you will be able to use your newly defined aliases and environment variables.

You can use the following function to find the biggest [number] in any string.

It returns the value of the biggest [number] as an Integer.

var biggestNumber = function(str) {
    var pattern = /\[([0-9]+)\]/g, match, biggest = 0;

    while ((match = pattern.exec(str)) !== null) {
        if (match.index === pattern.lastIndex) {
            pattern.lastIndex++;
        }
        match[1] = parseInt(match[1]);
        if(biggest < match[1]) {
            biggest = match[1];
        }
    }
    return biggest;
}

DEMO

The following demo calculates the biggest number in your textarea every time you click the button.

It allows you to play around with the textarea and re-test the function with a different text.

var biggestNumber = function(str) {_x000D_
    var pattern = /\[([0-9]+)\]/g, match, biggest = 0;_x000D_
_x000D_
    while ((match = pattern.exec(str)) !== null) {_x000D_
        if (match.index === pattern.lastIndex) {_x000D_
            pattern.lastIndex++;_x000D_
        }_x000D_
        match[1] = parseInt(match[1]);_x000D_
        if(biggest < match[1]) {_x000D_
            biggest = match[1];_x000D_
        }_x000D_
    }_x000D_
    return biggest;_x000D_
}_x000D_
_x000D_
document.getElementById("myButton").addEventListener("click", function() {_x000D_
    alert(biggestNumber(document.getElementById("myTextArea").value));_x000D_
});

<div>_x000D_
    <textarea rows="6" cols="50" id="myTextArea">_x000D_
this is a test [1] also this [2] is a test_x000D_
and again [18] this is a test. _x000D_
items[14].items[29].firstname too is a test!_x000D_
items[4].firstname too is a test!_x000D_
    </textarea>_x000D_
</div>_x000D_
_x000D_
<div>_x000D_
   <button id="myButton">Try me</button>_x000D_

My version of the accepted answer as a function using DATEPART, so I don't have to do a string comparison on the line with

DATENAME(dw, @StartDate) = 'Sunday'

Anyway, here's my business datediff function

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE FUNCTION BDATEDIFF
(
    @startdate as DATETIME,
    @enddate as DATETIME
)
RETURNS INT
AS
BEGIN
    DECLARE @res int

SET @res = (DATEDIFF(dd, @startdate, @enddate) + 1)
    -(DATEDIFF(wk, @startdate, @enddate) * 2)
    -(CASE WHEN DATEPART(dw, @startdate) = 1 THEN 1 ELSE 0 END)
    -(CASE WHEN DATEPART(dw, @enddate) = 7 THEN 1 ELSE 0 END)

    RETURN @res
END
GO

If you want plain C exports, use a C project not C++. C++ DLLs rely on name-mangling for all the C++isms (namespaces etc...). You can compile your code as C by going into your project settings under C/C++->Advanced, there is an option "Compile As" which corresponds to the compiler switches /TP and /TC.

If you still want to use C++ to write the internals of your lib but export some functions unmangled for use outside C++, see the second section below.

Exporting/Importing DLL Libs in VC++

What you really want to do is define a conditional macro in a header that will be included in all of the source files in your DLL project:

#ifdef LIBRARY_EXPORTS
#    define LIBRARY_API __declspec(dllexport)
#else
#    define LIBRARY_API __declspec(dllimport)
#endif

Then on a function that you want to be exported you use LIBRARY_API:

LIBRARY_API int GetCoolInteger();

In your library build project create a define LIBRARY_EXPORTS this will cause your functions to be exported for your DLL build.

Since LIBRARY_EXPORTS will not be defined in a project consuming the DLL, when that project includes the header file of your library all of the functions will be imported instead.

If your library is to be cross-platform you can define LIBRARY_API as nothing when not on Windows:

#ifdef _WIN32
#    ifdef LIBRARY_EXPORTS
#        define LIBRARY_API __declspec(dllexport)
#    else
#        define LIBRARY_API __declspec(dllimport)
#    endif
#elif
#    define LIBRARY_API
#endif

When using dllexport/dllimport you do not need to use DEF files, if you use DEF files you do not need to use dllexport/dllimport. The two methods accomplish the same task different ways, I believe that dllexport/dllimport is the recommended method out of the two.

Exporting unmangled functions from a C++ DLL for LoadLibrary/PInvoke

If you need this to use LoadLibrary and GetProcAddress, or maybe importing from another language (i.e PInvoke from .NET, or FFI in Python/R etc) you can use extern "C" inline with your dllexport to tell the C++ compiler not to mangle the names. And since we are using GetProcAddress instead of dllimport we don't need to do the ifdef dance from above, just a simple dllexport:

The Code:

#define EXTERN_DLL_EXPORT extern "C" __declspec(dllexport)

EXTERN_DLL_EXPORT int getEngineVersion() {
  return 1;
}

EXTERN_DLL_EXPORT void registerPlugin(Kernel &K) {
  K.getGraphicsServer().addGraphicsDriver(
    auto_ptr<GraphicsServer::GraphicsDriver>(new OpenGLGraphicsDriver())
  );
}

And here's what the exports look like with Dumpbin /exports:

  Dump of file opengl_plugin.dll

  File Type: DLL

  Section contains the following exports for opengl_plugin.dll

    00000000 characteristics
    49866068 time date stamp Sun Feb 01 19:54:32 2009
        0.00 version
           1 ordinal base
           2 number of functions
           2 number of names

    ordinal hint RVA      name

          1    0 0001110E getEngineVersion = @ILT+265(_getEngineVersion)
          2    1 00011028 registerPlugin = @ILT+35(_registerPlugin)

So this code works fine:

m_hDLL = ::LoadLibrary(T"opengl_plugin.dll");

m_pfnGetEngineVersion = reinterpret_cast<fnGetEngineVersion *>(
  ::GetProcAddress(m_hDLL, "getEngineVersion")
);
m_pfnRegisterPlugin = reinterpret_cast<fnRegisterPlugin *>(
  ::GetProcAddress(m_hDLL, "registerPlugin")
);

@RequestParam annotation tells Spring that it should map a request parameter from the GET/POST request to your method argument. For example:

request:

GET: http://someserver.org/path?name=John&surname=Smith

endpoint code:

public User getUser(@RequestParam(value = "name") String name, 
                    @RequestParam(value = "surname") String surname){ 
    ...  
    }

So basically, while @RequestBody maps entire user request (even for POST) to a String variable, @RequestParam does so with one (or more - but it is more complicated) request param to your method argument.

The duplicate values in any column can be deleted with a simple for loop.

Sub remove()
Dim a As Long
For a = Cells(Rows.Count, 1).End(xlUp).Row To 1 Step -1
If WorksheetFunction.CountIf(Range("A1:A" & a), Cells(a, 1)) > 1 Then Rows(a).Delete
Next
End Sub

Nto sure which RDBMS you are using, but if it is SQL Server you could look at rather using a CASE statement

Evaluates a list of conditions and returns one of multiple possible result expressions.

The CASE expression has two formats:

The simple CASE expression compares an expression to a set of simple expressions to determine the result.

The searched CASE expression evaluates a set of Boolean expressions to determine the result.

Both formats support an optional ELSE argument.

Here's an example:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def self.up
    rename_table :old_table_name, :new_table_name
  end

  def self.down
    rename_table :new_table_name, :old_table_name
  end
end

I had to go and rename the model declaration file manually.

Edit:

In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def change
    rename_table :old_table_name, :new_table_name
  end 
end

(You still have to go through and manually rename your files.)

In java you don't check if a key is pressed, instead you listen to KeyEvents. The right way to achieve your goal is to register a KeyEventDispatcher, and implement it to maintain the state of the desired key:

import java.awt.KeyEventDispatcher;
import java.awt.KeyboardFocusManager;
import java.awt.event.KeyEvent;

public class IsKeyPressed {
    private static volatile boolean wPressed = false;
    public static boolean isWPressed() {
        synchronized (IsKeyPressed.class) {
            return wPressed;
        }
    }

    public static void main(String[] args) {
        KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher() {

            @Override
            public boolean dispatchKeyEvent(KeyEvent ke) {
                synchronized (IsKeyPressed.class) {
                    switch (ke.getID()) {
                    case KeyEvent.KEY_PRESSED:
                        if (ke.getKeyCode() == KeyEvent.VK_W) {
                            wPressed = true;
                        }
                        break;

                    case KeyEvent.KEY_RELEASED:
                        if (ke.getKeyCode() == KeyEvent.VK_W) {
                            wPressed = false;
                        }
                        break;
                    }
                    return false;
                }
            }
        });
    }
}

Then you can always use:

if (IsKeyPressed.isWPressed()) {
    // do your thing.
}

You can, of course, use same method to implement isPressing("<some key>") with a map of keys and their state wrapped inside IsKeyPressed.

If you have successfully deleted from workspace tab but still it is showing in drop down menu. Then also you can successfully remove that by following these steps:

1. Go to C:/Users/user_name/.p4qt

user_name will be your username of your computer

2. Inside 001Clients folder WorkspaceSettings.xml file will be there.

There will be two tag

1. varName = "RecentlyUsedWorkspaces" remove the deleted workspace tag

2. A propertyList tag will be there with varName=deleted_workspace_name delete that tag.

from drop down menu workspace name will be deleted

Answer is you can't explicitly but you should be freeing memory in your routines.

Some tips though to help memory

• Make sure you set object to null before exiting your routine.
• Ensure you call Close on objects if they require it.
• Don't use global variables unless absolutely necessary

I would recommend checking the memory usage after performing the routine again and again you may have a memory leak.

Parris / kindall's answer join/return answer ported to Python 3:

from threading import Thread

def foo(bar):
    print('hello {0}'.format(bar))
    return "foo"

class ThreadWithReturnValue(Thread):
    def __init__(self, group=None, target=None, name=None, args=(), kwargs=None, *, daemon=None):
        Thread.__init__(self, group, target, name, args, kwargs, daemon=daemon)

        self._return = None

    def run(self):
        if self._target is not None:
            self._return = self._target(*self._args, **self._kwargs)

    def join(self):
        Thread.join(self)
        return self._return


twrv = ThreadWithReturnValue(target=foo, args=('world!',))

twrv.start()
print(twrv.join())   # prints foo

Note, the Thread class is implemented differently in Python 3.

I was also facing the same problem i did the following steps to resolve the issue

1. I edited the file /etc/php.ini and searched the path session.save_path = "/var/lib/php/session" you have to give your session info

2 After that just changed the permission given below *chown root.apache /var/lib/php/session * That's it. These above steps resolve my issue

as explained here

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Firefox stores that number in this setting (you find it in about:config): network.http.max-connections-per-server

For the max connections, Firefox stores that in this setting: network.http.max-connections

Here is a good article on creating and adding a class library. Even shows how to create Methods through the method wizard and how to use it in the application

I've come up with an awkward but functional solution for my problem. It works for a one-dimensional array (more dimensions would be tricky) and input that fits into a varchar:

  declare pos int;           -- Keeping track of the next item's position
  declare item varchar(100); -- A single item of the input
  declare breaker int;       -- Safeguard for while loop 

  -- The string must end with the delimiter
  if right(inputString, 1) <> '|' then
     set inputString = concat(inputString, '|');
  end if;

  DROP TABLE IF EXISTS MyTemporaryTable;
  CREATE TEMPORARY TABLE MyTemporaryTable ( columnName varchar(100) );
  set breaker = 0;

  while (breaker < 2000) && (length(inputString) > 1) do
     -- Iterate looking for the delimiter, add rows to temporary table.
     set breaker = breaker + 1;
     set pos = INSTR(inputString, '|');
     set item = LEFT(inputString, pos - 1);
     set inputString = substring(inputString, pos + 1);
     insert into MyTemporaryTable values(item);
  end while;

For example, input for this code could be the string Apple|Banana|Orange. MyTemporaryTable will be populated with three rows containing the strings Apple, Banana, and Orange respectively.

I thought the slow speed of string handling would render this approach useless, but it was quick enough (only a fraction of a second for a 1,000 entries array).

Hope this helps somebody.

What features of an IDE do you want? Integrated build engine? Debugger? Code highlighting? IntelliSense? Project management? Configuration management? Testing tools? Except for code highlighting, none of these are in your requirements.

So my suggestion is to use an editor that supports plugins, like Notepad++ (which you are already used to). If there's not already a plugin that does what you want, then write one.

I use Coda on Mac OS X.

Generally, it is assumed that name is always superseded by id. This is true, to some extent, but not for form fields and frame names, practically speaking. For example, with form elements the name attribute is used to determine the name-value pairs to be sent to a server-side program and should not be eliminated. Browsers do not use id in that manner. To be on the safe side, you could use name and id attributes on form elements. So, we would write the following:

<form id="myForm" name="myForm">
     <input type="text" id="userName" name="userName" />
</form>

To ensure compatibility, having matching name and id attribute values when both are defined is a good idea. However, be careful—some tags, particularly radio buttons, must have nonunique name values, but require unique id values. Once again, this should reference that id is not simply a replacement for name; they are different in purpose. Furthermore, do not discount the old-style approach, a deep look at modern libraries shows such syntax style used for performance and ease purposes at times. Your goal should always be in favor of compatibility.

Now in most elements, the name attribute has been deprecated in favor of the more ubiquitous id attribute. However, in some cases, particularly form fields (<button>, <input>, <select>, and <textarea>), the name attribute lives on because it continues to be required to set the name-value pair for form submission. Also, we find that some elements, notably frames and links, may continue to use the name attribute because it is often useful for retrieving these elements by name.

There is a clear distinction between id and name. Very often when name continues on, we can set the values the same. However, id must be unique, and name in some cases shouldn’t—think radio buttons. Sadly, the uniqueness of id values, while caught by markup validation, is not as consistent as it should be. CSS implementation in browsers will style objects that share an id value; thus, we may not catch markup or style errors that could affect our JavaScript until runtime.

This is taken from the book JavaScript- The Complete Reference by Thomas-Powell

This article here nicely explains it. Essentially, you can look at it as such:

CREATE TABLE t AS
SELECT 'a' v FROM dual UNION ALL
SELECT 'a'   FROM dual UNION ALL
SELECT 'a'   FROM dual UNION ALL
SELECT 'b'   FROM dual UNION ALL
SELECT 'c'   FROM dual UNION ALL
SELECT 'c'   FROM dual UNION ALL
SELECT 'd'   FROM dual UNION ALL
SELECT 'e'   FROM dual;

SELECT
  v,
  ROW_NUMBER() OVER (ORDER BY v) row_number,
  RANK()       OVER (ORDER BY v) rank,
  DENSE_RANK() OVER (ORDER BY v) dense_rank
FROM t
ORDER BY v;

The above will yield:

+---+------------+------+------------+
| V | ROW_NUMBER | RANK | DENSE_RANK |
+---+------------+------+------------+
| a |          1 |    1 |          1 |
| a |          2 |    1 |          1 |
| a |          3 |    1 |          1 |
| b |          4 |    4 |          2 |
| c |          5 |    5 |          3 |
| c |          6 |    5 |          3 |
| d |          7 |    7 |          4 |
| e |          8 |    8 |          5 |
+---+------------+------+------------+

In words

• ROW_NUMBER() attributes a unique value to each row
• RANK() attributes the same row number to the same value, leaving "holes"
• DENSE_RANK() attributes the same row number to the same value, leaving no "holes"

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

You can do something like

    SELECT *
      FROM (SELECT Fname FROM MyTbl ORDER BY Fname )
 WHERE rownum = 1;

You could also use the analytic functions RANK and/or DENSE_RANK, but ROWNUM is probably the easiest.

use simplejson or cjson for speedups

import simplejson as json

json.loads(obj)

or 

cjson.decode(obj)

urls.py:

#...    
url(r'element/update/(?P<pk>\d+)/$', 'element.views.element_update', name='element_update'),

views.py:

from django.shortcuts import redirect
from .models import Element


def element_info(request):
    # ...
    element = Element.object.get(pk=1)
    return redirect('element_update', pk=element.id)

def element_update(request, pk)
    # ...

I used the action delegate like this in a project once:

private static Dictionary<Type, Action<Control>> controldefaults = new Dictionary<Type, Action<Control>>() { 
            {typeof(TextBox), c => ((TextBox)c).Clear()},
            {typeof(CheckBox), c => ((CheckBox)c).Checked = false},
            {typeof(ListBox), c => ((ListBox)c).Items.Clear()},
            {typeof(RadioButton), c => ((RadioButton)c).Checked = false},
            {typeof(GroupBox), c => ((GroupBox)c).Controls.ClearControls()},
            {typeof(Panel), c => ((Panel)c).Controls.ClearControls()}
    };

which all it does is store a action(method call) against a type of control so that you can clear all the controls on a form back to there defaults.

If your application only works in portrait orientation, this is enough:

[[[UIApplication sharedApplication] keyWindow] addSubview:yourView]

And your view will not be shown over keyboard and status bar.

If you want to get a topmost view that over keyboard or status bar, or you want the topmost view can rotate correctly with devices, please try this framework:

https://github.com/HarrisonXi/TopmostView

It supports iOS7/8/9.

Edit: Google engineers do not recommend this approach, as described by Dianne Hackborn (a.k.a. hackbod) in this StackOverflow post. Check out this blog post for more information.

You have to add this to the activity declaration in the manifest:

android:configChanges="orientation|screenSize"

so it looks like

<activity android:label="@string/app_name" 
        android:configChanges="orientation|screenSize|keyboardHidden" 
        android:name=".your.package">

The matter is that the system destroys the activity when a change in the configuration occurs. See ConfigurationChanges.

So putting that in the configuration file avoids the system to destroy your activity. Instead it invokes the onConfigurationChanged(Configuration) method.

In c and C++ there is no data type called BOOLEAN Thats why it uses 1 and 0 as true false value. and in JAVA 1 and 0 are count as an INTEGER type so it produces error in java. And java have its own boolean values true and false with boolean data type.

happy programming..

Statement stmt3 = con.createStatement();

ResultSet rs3 = stmt3.executeQuery("SELECT COUNT(*) AS count FROM "+lastTempTable+" ;");

count = rs3.getInt("count");

So basically something like this:

public static String appendWithDelimiter(String original, String addition, String delimiter) {

if (original.equals("")) {
    return addition;
} else {
    StringBuilder sb = new StringBuilder(original.length() + addition.length() + delimiter.length());
        sb.append(original);
        sb.append(delimiter);
        sb.append(addition);
        return sb.toString();
    }
}

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

Let's do a test with 2 examples:

    <?php    
    $memory = (int)ini_get("memory_limit"); // Display your current value in php.ini (for example: 64M)
    echo "original memory: ".$memory."<br>";
    ini_set('memory_limit','128M'); // Try to override the memory limit for this script
    echo "new memory:".$memory;
    }
    // Will display:
    // original memory: 64
    // new memory: 64
    ?>

The above example doesn't work for overriding the memory_limit value. But This will work:

    <?php
    $memory = (int)ini_get("memory_limit"); // get the current value
    ini_set('memory_limit','128'); // override the value
    echo "original memory: ".$memory."<br>"; // echo the original value
    $new_memory = (int)ini_get("memory_limit"); // get the new value
    echo "new memory: ".$new_memory;  // echo the new value
    // Will display:
    // original memory: 64
    // new memory: 128
    ?>

You have to place the ini_set('memory_limit','128M'); at the top of the file or at least before any echo.

As for me, suhosin wasn't the solution because it doesn't even appear in my phpinfo(), but this worked:

    <?php
    ini_set('memory_limit','2048M'); // set at the top of the file
    (...)
    ?>

put an overlay on the page

#loading-mask {
    background-color: white;
    height: 100%;
    left: 0;
    position: fixed;
    top: 0;
    width: 100%;
    z-index: 9999;
}

and then delete that element in a window.onload handler or, hide it

window.onload=function() {
    document.getElementById('loading-mask').style.display='none';
}

Of course you should use your javascript library (jquery,prototype..) specific onload handler if you are using a library.

Just go to Web.Config from Main folder, not the one in Views Folder:

configSections

section name="entityFramework" type="System.Data. .....,Version=" <strong>5</strong>.0.0.0"..

<..>

ADJUST THE VERSION OF EntityFramework you have installed, ex. like Version 6.0.0.0"

You can use below command to see who have changed what in a file.

git blame <filename>

I had the same problem, and since this question was the first hit on google, I'll add my solution too. For me, it was a missing format attribute in an attr element in res/values/attrs.xml.

Add your own local JAR in POM file and use that in maven build.

mvn install:install-file -Dfile=path-to-jar -DgroupId=owngroupid -DartifactId=ownartifactid -Dversion=ownversion -Dpackaging=jar

For example:

mvn install:install-file -Dfile=path-to-jar -DgroupId=com.decompiler -DartifactId=jd-core-java -Dversion=1.2 -Dpackaging=jar

Then add it to the POM like this:

scrollHeight is a property of a DOM object, not a function:

Height of the scroll view of an element; it includes the element padding but not its margin.

Given this:

<div id="x" style="height: 100px; overflow: hidden;">
    <div style="height: 200px;">
        pancakes
    </div>
</div>

This yields 200:

$('#x')[0].scrollHeight

For example: http://jsfiddle.net/ambiguous/u69kQ/2/ (run with the JavaScript console open).

On many source packages (e.g. for most GNU software), the building system may know about the DESTDIR make variable, so you can often do:

 make install DESTDIR=/tmp/myinst/
 sudo cp -va /tmp/myinst/ /

The advantage of this approach is that make install don't need to run as root, so you cannot end up with files compiled as root (or root-owned files in your build tree).

Not my answer :

I wasn't too happy with the answers above and some additional searching yielded this :

SELECT SYSDATE AS current_date,

       SYSDATE + 1 AS plus_1_day,

       SYSDATE + 1/24 AS plus_1_hours,

       SYSDATE + 1/24/60 AS plus_1_minutes,

       SYSDATE + 1/24/60/60 AS plus_1_seconds

FROM   dual;

which I found very helpful. From http://sqlbisam.blogspot.com/2014/01/add-date-interval-to-date-or-dateadd.html

You could also have embed all of your template views into your main html file. For Example:

<body ng-app="testApp">
  <h1>Test App</h1>
  <div ng-view></div>
  <script type = "text/ng-template" id = "index.html">
    <h1>Index Page</h1>
    <p>{{message}}</p>
  </script>
  <script type = "text/ng-template" id = "home.html">
    <h1>Home Page</h1>
    <p>{{message}}</p>
  </script>
</body>

This way if each template requires a different controller then you can still use the angular-router. See this plunk for a working example http://plnkr.co/edit/9X0fT0Q9MlXtHVVQLhgr?p=preview

This way once the application is sent from the server to your client, it is completely self contained assuming that it doesn't need to make any data requests, etc.

Suppose you want the value of the first item.

ListBox list = new ListBox();
Console.Write(list.Items[0].Value);

In my python interpreter exit is actually a string and not a function -- 'Use Ctrl-D (i.e. EOF) to exit.'. You can check on your interpreter by entering type(exit)

In active python what is happening is that exit is a function. If you do not call the function it will print out the string representation of the object. This is the default behaviour for any object returned. It's just that the designers thought people might try to type exit to exit the interpreter, so they made the string representation of the exit function a helpful message. You can check this behaviour by typing str(exit) or even print exit.

Here is my version which adds the tcp port in case it's not 80 or 443:

function url(s) {
    var l = window.location;
    return ((l.protocol === "https:") ? "wss://" : "ws://") + l.hostname + (((l.port != 80) && (l.port != 443)) ? ":" + l.port : "") + l.pathname + s;
}

Edit 1: Improved version as by suggestion of @kanaka :

function url(s) {
    var l = window.location;
    return ((l.protocol === "https:") ? "wss://" : "ws://") + l.host + l.pathname + s;
}

Edit 2: Nowadays I create the WebSocket this:

var s = new WebSocket(((window.location.protocol === "https:") ? "wss://" : "ws://") + window.location.host + "/ws");

I'm super late to the party, but SO_NOSIGPIPE isn't portable, and might not work on your system (it seems to be a BSD thing).

A nice alternative if you're on, say, a Linux system without SO_NOSIGPIPE would be to set the MSG_NOSIGNAL flag on your send(2) call.

Example replacing write(...) by send(...,MSG_NOSIGNAL) (see nobar's comment)

char buf[888];
//write( sockfd, buf, sizeof(buf) );
send(    sockfd, buf, sizeof(buf), MSG_NOSIGNAL );

If you are using Angular, go like this:

<select>_x000D_
    <option [ngValue]="undefined"  disabled selected>Select your option</option>_x000D_
    <option [ngValue]="hurr">Durr</option>_x000D_
</select>

If you have another file in same directory, you can either do:

bash another_script.sh

or

source another_script.sh

or

. another_script.sh

When you use bash instead of source, the script cannot alter environment of the parent script. The . command is POSIX standard while source command is a more readable bash synonym for . (I prefer source over .). If your script resides elsewhere just provide path to that script. Both relative as well as full path should work.

There's an easier way:

find ... | while read -r file; do
    echo "look at my $file, my $file is amazing";
done

Alternatively:

while read -r file; do
    echo "look at my $file, my $file is amazing";
done <<< "$(find ...)"

I think this link will do your homework: http://ootips.org/uml-hasa.html

To understand the terms I remember an example in my early programming days:

If you have a 'chess board' object that contains 'box' objects that is composition because if the 'chess board' is deleted there is no reason for the boxes to exist anymore.

If you have a 'square' object that have a 'color' object and the square gets deleted the 'color' object may still exist, that is aggregation

Both of them are associations, the main difference is conceptual

In addition to the other suggestions - you can also wrap the flag in a control class and make a final instance of it in your parent class:

public class Test {
  class Control {
    public volatile boolean flag = false;
  }
  final Control control = new Control();

  class T1 implements Runnable {
    @Override
    public void run() {
      while ( !control.flag ) {

      }
    }
  }

  class T2 implements Runnable {
    @Override
    public void run() {
      while ( !control.flag ) {

      }
    }
  }

  private void test() {
    T1 main = new T1();
    T2 help = new T2();

    new Thread(main).start();
    new Thread(help).start();
  }

  public static void main(String[] args) throws InterruptedException {
    try {
      Test test = new Test();
      test.test();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Reason of the error: Package name left blank while creating a class. This make use of default package. Thus causes this error.

Quick fix:

1. Create a package eg. helloWorld inside the src folder.
2. Move helloWorld.java file in that package. Just drag and drop on the package. Error should disappear.

Explanation:

• My Eclipse version: 2020-09 (4.17.0)
• My Java version: Java 15, 2020-09-15

Latest version of Eclipse required java11 or above. The module feature is introduced in java9 and onward. It was proposed in 2005 for Java7 but later suspended. Java is object oriented based. And module is the moduler approach which can be seen in language like C. It was harder to implement it, due to which it took long time for the release. Source: Understanding Java 9 Modules

When you create a new project in Eclipse then by default module feature is selected. And in Eclipse-2020-09-R, a pop-up appears which ask for creation of module-info.java file. If you select don't create then module-info.java will not create and your project will free from this issue.

Best practice is while crating project, after giving project name. Click on next button instead of finish. On next page at the bottom it ask for creation of module-info.java file. Select or deselect as per need.

If selected: (by default) click on finish button and give name for module. Now while creating a class don't forget to give package name. Whenever you create a class just give package name. Any name, just don't left it blank.

If deselect: No issue

You want a java decompiler, you can use the command line tool javap to do this. Also, Java Decompiler HOW-TO describes how you can decompile a class file.

You should use:

var autocompleteIds= $("#EventId");
autocompleteIds.empty().append('<option value="Id">Text</option>').val("Id").trigger('change');

// For set multi selected values
var data =  [];//Array Ids
var option =  [];//Array options of Ids above
autocompleteIds.empty().append(option).val(data).trigger('change');

// Callback handler that will be called on success
request.done(function (response, textStatus, jqXHR) {
    // append the new option
    $("#EventId").append('<option value="' + response.id + '">' + response.text + '</option>');

    // get a list of selected values if any - or create an empty array
    var selectedValues = $("#EventId").val();
    if (selectedValues == null) {
        selectedValues = new Array();
    }
    selectedValues.push(response.id);   // add the newly created option to the list of selected items
    $("#EventId").val(selectedValues).trigger('change');   // have select2 do it's thing
});

For me, I checked the CMakeError.log file and found:

[...] error MSB8036: The Windows SDK version 8.1 was not found. Install the required version of Windows SDK or change the SDK version in the project property pages or by right-clicking the solution and selecting "Retarget solution".

This is despite using Visual Studio 2017 on Windows 7. So it appears that CMake is trying to build its detection project with the Windows 8.1 SDK.

I used the Visual Studio installer to add that component and now CMake is happy as a clam.

I think the best way is Convert.ToInt32.

Apache Commons Daemon is a good alternative. It has Procrun for windows services, and Jsvc for unix daemons. It uses less restrictive Apache license, and Apache Tomcat uses it as a part of itself to run on Windows and Linux! To get it work is a bit tricky, but there is an exhaustive article with working example.

Besides that, you may look at the bin\service.bat in Apache Tomcat to get an idea how to setup the service. In Tomcat they rename the Procrun binaries (prunsrv.exe -> tomcat6.exe, prunmgr.exe -> tomcat6w.exe).

Something I struggled with using Procrun, your start and stop methods must accept the parameters (String[] argv). For example "start(String[] argv)" and "stop(String[] argv)" would work, but "start()" and "stop()" would cause errors. If you can't modify those calls, consider making a bootstrapper class that can massage those calls to fit your needs.

If you know what element you want to retrieve, then you already have the element. The only question for a Set to answer, given an element, is whether it contains() it or not.

If you want to iterator over the elements, just use a Set.iterator().

It sounds like what you're trying to do is designate a canonical element for an equivalence class of elements. You can use a Map<MyObject,MyObject> to do this. See this SO question or this one for a discussion.

If you are really determined to find an element that .equals() your original element with the constraint that you MUST use the HashSet, I think you're stuck with iterating over it and checking equals() yourself. The API doesn't let you grab something by its hash code. So you could do:

MyObject findIfPresent(MyObject source, HashSet<MyObject> set)

Brute force and O(n) ugly, but if that's what you need to do...

Here are various optimisations and applications of proper Python style to make your code a lot neater. I've put in some optional code using the csv module, which is more desirable than parsing it manually. I've also put in a bit of namedtuple goodness, but I don't use the attributes that then provides. Names of the parts of the namedtuple are inaccurate, you'll need to correct them.

import csv
from collections import namedtuple
from time import localtime, strftime

# Method one, reading the file into lists manually (less desirable)
with open('grades.dat') as files:
    grades = [[e.strip() for e in s.split(',')] for s in files]

# Method two, using csv and namedtuple
StudentRecord = namedtuple('StudentRecord', 'id, lastname, firstname, something, homework1, homework2, homework3, homework4, homework5, homework6, homework7, exam1, exam2, exam3')
grades = map(StudentRecord._make, csv.reader(open('grades.dat')))
# Now you could have student.id, student.lastname, etc.
# Skipping the namedtuple, you could do grades = map(tuple, csv.reader(open('grades.dat')))

request = open('requests.dat', 'w')
cont = 'y'

while cont.lower() == 'y':
    answer = raw_input('Please enter the Student I.D. of whom you are looking: ')
    for student in grades:
        if answer == student[0]:
            print '%s, %s      %s      %s' % (student[1], student[2], student[0], student[3])
            time = strftime('%a, %b %d %Y %H:%M:%S', localtime())
            print time
            print 'Exams - %s, %s, %s' % student[11:14]
            print 'Homework - %s, %s, %s, %s, %s, %s, %s' % student[4:11]
            total = sum(int(x) for x in student[4:14])
            print 'Total points earned - %d' % total
            grade = total / 5.5
            if grade >= 90:
                letter = 'an A'
            elif grade >= 80:
                letter = 'a B'
            elif grade >= 70:
                letter = 'a C'
            elif grade >= 60:
                letter = 'a D'
            else:
                letter = 'an F'

            if letter = 'an A':
                print 'Grade: %s, that is equal to %s.' % (grade, letter)
            else:
                print 'Grade: %.2f, that is equal to %s.' % (grade, letter)

            request.write('%s %s, %s %s\n' % (student[0], student[1], student[2], time))


    print
    cont = raw_input('Would you like to search again? ')

print 'Goodbye.'

explained with respect to, linux/unix based systems, though it's a basic concept for all other computing systems.

*

Linkers and Loaders from LinuxJournal explains this concept with clarity. It also explains how the classic name a.out came. (assembler output)

A quick summary,

c program --> [compiler] --> objectFile --> [linker] --> executable file (say, a.out)

we got the executable, now give this file to your friend or to your customer who is in need of this software :)

when they run this software, say by typing it in command line ./a.out

execute in command line ./a.out --> [Loader] --> [execve] --> program is loaded in memory

Once the program is loaded into the memory, control is transferred to this program by making the PC (program counter) pointing to the first instruction of a.out

To Solve this problem go to Solution Explorer And right click reference and click add reference and chose .net and find system.configuration select an click ok

I believe it causes the standard event to not happen.

In your example the browser will not attempt to go to #.

An alternative, but a bit slower alternative is to do it over indexing.

np.isnan(data)[np.isnan(data) == False].size

In [30]: %timeit np.isnan(data)[np.isnan(data) == False].size
1 loops, best of 3: 498 ms per loop 

The double use of np.isnan(data) and the == operator might be a bit overkill and so I posted the answer only for completeness.

Use fabs() (in math.h) to get absolute-value for double:

double d1 = fabs(-3.8951);

Example:

  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build --prod",
    "build_c": "ng build --prod && del \"../../server/front-end/*.*\" /s /q & xcopy /s dist \"../../server/front-end\"",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

As you can see, the script "build_c" is building the angular application, then deletes all old files from a directory, then finally copies the result build files.

If I understood you well I think you have two ways of doing it.

First you could try ngSwitch and the second possible way would be creating you own filter. Probably ngSwitch is the right aproach but if you want to hide or show inline content just using {{}} filter is the way to go.

Here is a fiddle with a simple filter as an example.

<div ng-app="exapleOfFilter">
  <div ng-controller="Ctrl">
    <input ng-model="greeting" type="greeting">
      <br><br>
      <h1>{{greeting|isHello}}</h1>
  </div>
</div>

angular.module('exapleOfFilter', []).
  filter('isHello', function() {
    return function(input) {
      // conditional you want to apply
      if (input === 'hello') {
        return input;
      }
      return '';
    }
  });

function Ctrl($scope) {
  $scope.greeting = 'hello';
}

I noticed something else about your coding.... look

INSERT INTO reports_services (id,title,description,cost) VALUES (0, 'test title', 'test decription ', '3.80')

in your "CREATE TABLE" code you have the id set to "AUTO_INCREMENT" which means it's automatically generating a result for that field.... but in your above code you include it as one of the insertions and in the "VALUES" you have a 0 there... idk if that's your way of telling us you left it blank because it's set to AUTO_INC. or if that's the actual code you have... if it's the code you have not only should you not be trying to send data to a field set to generate it automatically, but the RIGHT WAY to do it WRONG would be

'0',

you put

0,

lol....so that might be causing some of the problem... I also just noticed in the code after "test description" you have a space before the '.... that might be throwing something off too.... idk.. I hope this helps n maybe resolves some other problem you might be pulling your hair out about now.... speaking of which.... I need to figure out my problem before I tear all my hair out..... good luck.. :)

UPDATE.....

I almost forgot... if you have the 0 there to show that it's blank... you could be entering "test title" as the id and "test description" as the title then "3.whatever cents" for the description leaving "cost" empty...... which could be why it maxed out because if I'm not mistaking you have it set to NOT NULL.... and you left it null... so it forced something... maybe.... lol

You have more than one form tags with runat="server" on your template, most probably you have one in your master page, remove one on your aspx page, it is not needed if already have form in master page file which is surrounding your content place holders.

Try to remove that tag:

<form id="formID" runat="server">

and of course closing tag:

</form>

It solves to me, for my purposes:

.select-container {
  position:relative;
  width:200px;
  height:18px;
  overflow:hidden;
  border:1px solid white !important
}
.select-container select {
  position:relative;
  left:-2px;
  top:-2px
}

To put more style will be necessary to use nested divs .

For unsigned data type there is no sign bit and all bits are for data ; whereas for signed data type MSB is indicated sign bit and remaining bits are for data.

To find the range do following things :

Step:1 -> Find out no of bytes for the give data type.

Step:2 -> Apply following calculations.

      Let n = no of bits in data type  

      For signed data type ::
            Lower Range = -(2^(n-1)) 
            Upper Range = (2^(n-1)) - 1)  

      For unsigned data type ::
            Lower Range = 0 
            Upper Range = (2^(n)) - 1 

For e.g.

For unsigned int size = 4 bytes (32 bits) --> Range [0 , (2^(32)) - 1]

For signed int size = 4 bytes (32 bits) --> Range [-(2^(32-1)) , (2^(32-1)) - 1]

That means sql group by 1st column in your select clause, we always use this GROUP BY 1 together with ORDER BY 1, besides you can also use like this GROUP BY 1,2,3.., of course it is convenient for us but you need to pay attention to that condition the result may be not what you want if some one has modified your select columns, and it's not visualized

import android.graphics.Color;

import java.util.Random;

public class ColorDiagram {
    // Member variables (properties about the object)
    public String[] mColors = {

            "#3079ab", // dark blue
            "#c25975", // mauve

            "#b7c0c7"  // light gray
    };

    // Method (abilities: things the object can do)
    public int getColor() {
        String color = "";

        // Randomly select a fact
        Random randomGenerator = new Random(); // Construct a new Random number generator
        int randomNumber = randomGenerator.nextInt(mColors.length);

        color = mColors[randomNumber];
        int colorAsInt = Color.parseColor(color);

        return colorAsInt;
    }
}

This is the command that you need to execute on the mirror:

git remote update

I just wanted to provide a bit of an update/special case since it looks like people still come here. If you're using a multi-index or otherwise using an index-slicer the inplace=True option may not be enough to update the slice you've chosen. For example in a 2x2 level multi-index this will not change any values (as of pandas 0.15):

idx = pd.IndexSlice
df.loc[idx[:,mask_1],idx[mask_2,:]].fillna(value=0,inplace=True)

The "problem" is that the chaining breaks the fillna ability to update the original dataframe. I put "problem" in quotes because there are good reasons for the design decisions that led to not interpreting through these chains in certain situations. Also, this is a complex example (though I really ran into it), but the same may apply to fewer levels of indexes depending on how you slice.

The solution is DataFrame.update:

df.update(df.loc[idx[:,mask_1],idx[[mask_2],:]].fillna(value=0))

It's one line, reads reasonably well (sort of) and eliminates any unnecessary messing with intermediate variables or loops while allowing you to apply fillna to any multi-level slice you like!

If anybody can find places this doesn't work please post in the comments, I've been messing with it and looking at the source and it seems to solve at least my multi-index slice problems.

For enums, I test them only when they actually have methods in them. If it's a pure value-only enum like your example, I'd say don't bother.

But since you're keen on testing it, going with your second option is much better than the first. The problem with the first is that if you use an IDE, any renaming on the enums would also rename the ones in your test class.

You're using JSTL 2.0 right? You don't need to put <c:out/> around all variables. Have you tried something like this?

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
  <c:set var="myVar" value="${myVar}${currentItem}" />
</c:forEach>

Edit: Beaten by the above

You can expend the following function in order to pull out more parameters from the DB before the insert:

--
-- insert_employee  (Function) 
--
CREATE OR REPLACE FUNCTION insert_employee(p_emp_id in number, p_emp_name in varchar2, p_emp_address in varchar2, p_emp_state in varchar2, p_emp_position in varchar2, p_emp_manager in varchar2) 
RETURN VARCHAR2 AS

   p_state_id varchar2(30) := '';
 BEGIN    
      select state_id 
      into   p_state_id
      from states where lower(emp_state) = state_name;

      INSERT INTO Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager) VALUES 
                (p_emp_id, p_emp_name, p_emp_address, p_state_id, p_emp_position, p_emp_manager);

    return 'SUCCESS';

 EXCEPTION 
   WHEN others THEN
    RETURN 'FAIL';
 END;
/

From vim: ]p

From outside: "*]p or "+]p

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

if you remove the indent at the like below, it will search and replace in multiple line. See below for example.

def replace(file, pattern, subst):
    #Create temp file
    fh, abs_path = mkstemp()
    print fh, abs_path
    new_file = open(abs_path,'w')
    old_file = open(file)
    for line in old_file:
        new_file.write(line.replace(pattern, subst))
    #close temp file
    new_file.close()
    close(fh)
    old_file.close()
    #Remove original file
    remove(file)
    #Move new file
    move(abs_path, file)

A simple comparison should be

ReactJs

return(
    <div>
      <p>Hello World</p>
    </div>
)

React Native

return(
    <View>
      <Text>Hello World</Text>
    </View>
)

React Native don't have Html Elements like div, p, h1, etc, instead it have components that make sense for mobile.

Update your format to:

SimpleDateFormat sdf=new SimpleDateFormat("E MMM dd hh:mm:ss Z yyyy");

The simplest way is to simply use the following line of jquery, using this you don't get the /fakepath nonsense, you straight up get the file that was uploaded:

$('input[type=file]')[0].files[0]; // This gets the file
$('#idOfFileUpload')[0].files[0]; // This gets the file with the specified id

Some other useful commands are:

To get the name of the file:

$('input[type=file]')[0].files[0].name; // This gets the file name

To get the type of the file:

If I were to upload a PNG, it would return image/png

$("#imgUpload")[0].files[0].type

To get the size (in bytes) of the file:

$("#imgUpload")[0].files[0].size

Also you don't have to use these commands on('change', you can get the values at any time, for instance you may have a file upload and when the user clicks upload, you simply use the commands I listed.

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

I came across a case where I thought I wanted to pass the "address" of an object property as data to another function and populate the object (with AJAX), do lookup from address array, and display in that other function. I couldn't use dot notation without doing string acrobatics so I thought an array might be nice to pass instead. I ended-up doing something different anyway, but seemed related to this post.

Here's a sample of a language file object like the one I wanted data from:

const locs = {
  "audioPlayer": {
    "controls": {
      "start": "start",
      "stop": "stop"
    },
    "heading": "Use controls to start and stop audio."
  }
}

I wanted to be able to pass an array such as: ["audioPlayer", "controls", "stop"] to access the language text, "stop" in this case.

I created this little function that looks-up the "least specific" (first) address parameter, and reassigns the returned object to itself. Then it is ready to look-up the next-most-specific address parameter if one exists.

function getText(selectionArray, obj) {
  selectionArray.forEach(key => {
    obj = obj[key];
  });
  return obj;
}

usage:

/* returns 'stop' */
console.log(getText(["audioPlayer", "controls", "stop"], locs)); 

/* returns 'use controls to start and stop audio.' */
console.log(getText(["audioPlayer", "heading"], locs));

For Bootstrap 4, a new class was released for this. According to the utilties docs:

Apply the class sticky-top.

<div class="sticky-top">...</div>

You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :

BEGIN TRANSACTION

update A
set A.ORG_NAME =  @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID

update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
    on B.ORG_ID = A.ORG_ID
    and A.ORG_ID = @ORG_ID

I've used Xavier's answer quite a bit. I want to add that restricting the package version to a specified range is easy and useful in the latest versions of NuGet.

For example, if you never want Newtonsoft.Json to be updated past version 3.x.x in your project, change the corresponding package element in your packages.config file to look like this:

<package id="Newtonsoft.Json" version="3.5.8" allowedVersions="[3.0, 4.0)" targetFramework="net40" />

Notice the allowedVersions attribute. This will limit the version of that package to versions between 3.0 (inclusive) and 4.0 (exclusive). Then, when you do an Update-Package on the whole solution, you don't need to worry about that particular package being updated past version 3.x.x.

The documentation for this functionality is here.

There is a major gotcha associated with getting an ASCII code of a char value.

In the proper sense, it can't be done.

It's because char has a range of 65535 whereas ASCII is restricted to 128. There is a huge amount of characters that have no ASCII representation at all.

The proper way would be to use a Unicode code point which is the standard numerical equivalent of a character in the Java universe.

Thankfully, Unicode is a complete superset of ASCII. That means Unicode numbers for Latin characters are equal to their ASCII counterparts. For example, A in Unicode is U+0041 or 65 in decimal. In contrast, ASCII has no mapping for 99% of char-s. Long story short:

char ch = 'A';
int cp = String.valueOf(ch).codePointAt(0);

Furthermore, a 16-bit primitive char actually represents a code unit, not a character and is thus restricted to Basic Multilingual Plane, for historical reasons. Entities beyond it require Character objects which deal away with the fixed bit-length limitation.

Use this:

document.write('<td width="74"><button id="button" type="button" onclick="myfunction('" + name + "')">click</button></td>')

In addition to accepted answer, if you're using Entity Migrations for updating database, you should add this line at the beggining of the Up() function in your migration file:

Sql("alter table dbo.CompanyTransactions drop constraint [df__CompanyTr__Creat__0cdae408];");

You can find the constraint name in the error at nuget packet manager console which starts with FK_dbo.
