Use tow function to solve it ,Very simple and useful:

HTML:

<input class="int-number" type="text" />
<input class="decimal-number" type="text" />

JQuery:

//Integer Number
$(document).on("input", ".int-number", function (e) {
  this.value = this.value.replace(/[^0-9]/g, '');
});

//Decimal Number
$(document).on("input", ".decimal-number", function (e) {
    this.value = this.value.replace(/[^0-9.]/g, '').replace(/(\..*)\./g, '$1');
});

See this IEEE_754_types.h header for the union types to extract: float, double and long double, (endianness handled). Here is an extract:

And see dtoa_base.c for a demonstration of how to convert a double value to string form.

Furthermore, check out section 1.2.1.1.4.2 - Floating-Point Type Memory Layout of the C/CPP Reference Book, it explains super well and in simple terms the memory representation/layout of all the floating-point types and how to decode them (w/ illustrations) following the actually IEEE 754 Floating-Point specification.

It also has links to really really good ressources that explain even deeper.

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

Assuming type TreeMap<String,Integer> :

for(Map.Entry<String,Integer> entry : treeMap.entrySet()) {
  String key = entry.getKey();
  Integer value = entry.getValue();

  System.out.println(key + " => " + value);
}

(key and Value types can be any class of course)

There are legitimate technical reasons to want a generalized solution to the problem of bash alias not having a mechanism to take a reposition arbitrary arguments. One reason is if the command you wish to execute would be adversely affected by the changes to the environment that result from executing a function. In all other cases, functions should be used.

What recently compelled me to attempt a solution to this is that I wanted to create some abbreviated commands for printing the definitions of variables and functions. So I wrote some functions for that purpose. However, there are certain variables which are (or may be) changed by a function call itself. Among them are:

FUNCNAME BASH_SOURCE BASH_LINENO BASH_ARGC BASH_ARGV

The basic command I had been using (in a function) to print variable defns. in the form output by the set command was:

sv () { set | grep --color=never -- "^$1=.*"; }

E.g.:

> V=voodoo
sv V
V=voodoo

Problem: This won't print the definitions of the variables mentioned above as they are in the current context, e.g., if in an interactive shell prompt (or not in any function calls), FUNCNAME isn't defined. But my function tells me the wrong information:

> sv FUNCNAME
FUNCNAME=([0]="sv")

One solution I came up with has been mentioned by others in other posts on this topic. For this specific command to print variable defns., and which requires only one argument, I did this:

alias asv='(grep -- "^$(cat -)=.*" <(set)) <<<'

Which gives the correct output (none), and result status (false):

> asv FUNCNAME
> echo $?
1

However, I still felt compelled to find a solution that works for arbitrary numbers of arguments.

A General Solution To Passing Arbitrary Arguments To A Bash Aliased Command:

# (I put this code in a file "alias-arg.sh"):

# cmd [arg1 ...] – an experimental command that optionally takes args,
# which are printed as "cmd(arg1 ...)"
#
# Also sets global variable "CMD_DONE" to "true".
#
cmd () { echo "cmd($@)"; declare -g CMD_DONE=true; }

# Now set up an alias "ac2" that passes to cmd two arguments placed
# after the alias, but passes them to cmd with their order reversed:
#
# ac2 cmd_arg2 cmd_arg1 – calls "cmd" as: "cmd cmd_arg1 cmd_arg2"
#
alias ac2='
    # Set up cmd to be execed after f() finishes:
    #
    trap '\''cmd "${CMD_ARGV[1]}" "${CMD_ARGV[0]}"'\'' SIGUSR1;
    #        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    #       (^This is the actually execed command^)
    #
    # f [arg0 arg1 ...] – acquires args and sets up trap to run cmd:
    f () {
        declare -ag CMD_ARGV=("$@");  # array to give args to cmd
        kill -SIGUSR1 $$;             # this causes cmd to be run
        trap SIGUSR1;                 # unset the trap for SIGUSR1
        unset CMD_ARGV;               # clean up env...
        unset f;                      # incl. this function!
    };
    f'  # Finally, exec f, which will receive the args following "ac2".

E.g.:

> . alias-arg.sh
> ac2 one two
cmd(two one)
>
> # Check to see that command run via trap affects this environment:
> asv CMD_DONE
CMD_DONE=true

A nice thing about this solution is that all the special tricks used to handle positional parameters (arguments) to commands will work when composing the trapped command. The only difference is that array syntax must be used.

E.g.,

If you want "$@", use "${CMD_ARGV[@]}".

If you want "$#", use "${#CMD_ARGV[@]}".

Etc.

You can use Files#readAllLines() to get all lines of a text file into a List<String>.

for (String line : Files.readAllLines(Paths.get("/path/to/file.txt"))) {
    // ...
}

Tutorial: Basic I/O > File I/O > Reading, Writing and Creating text files

You can use String#split() to split a String in parts based on a regular expression.

for (String part : line.split("\\s+")) {
    // ...
}

Tutorial: Numbers and Strings > Strings > Manipulating Characters in a String

You can use Integer#valueOf() to convert a String into an Integer.

Integer i = Integer.valueOf(part);

Tutorial: Numbers and Strings > Strings > Converting between Numbers and Strings

You can use List#add() to add an element to a List.

numbers.add(i);

Tutorial: Interfaces > The List Interface

So, in a nutshell (assuming that the file doesn't have empty lines nor trailing/leading whitespace).

List<Integer> numbers = new ArrayList<>();
for (String line : Files.readAllLines(Paths.get("/path/to/file.txt"))) {
    for (String part : line.split("\\s+")) {
        Integer i = Integer.valueOf(part);
        numbers.add(i);
    }
}

If you happen to be at Java 8 already, then you can even use Stream API for this, starting with Files#lines().

List<Integer> numbers = Files.lines(Paths.get("/path/to/test.txt"))
    .map(line -> line.split("\\s+")).flatMap(Arrays::stream)
    .map(Integer::valueOf)
    .collect(Collectors.toList());

Tutorial: Processing data with Java 8 streams

There are many efficient ways to test primality (and this isn't one of them), but the loop you wrote can be concisely rewritten in Python:

def is_prime(a):
    return all(a % i for i in xrange(2, a))

That is, a is prime if all numbers between 2 and a (not inclusive) give non-zero remainder when divided into a.

You can use

string extension = System.IO.Path.GetExtension(filename);

And then remove the extension manually:

string result = filename.Substring(0, filename.Length - extension.Length);

This is how I handle iPhone (and similar) devices [not iPad]:

In my CSS file:

@media only screen and (max-width: 480px), only screen and (max-device-width: 480px) {
   /* CSS overrides for mobile here */
}

In the head of my HTML document:

<meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=no">

This is a very common question seen on Stackoverflow.

The important part here is not the command displayed in the error, but what the actual error tells you instead.

a Quick breakdown on why this error is received.

cmd.exe Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.

How do I fix this:

When Actual Command/executable fails

First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.

If you have any executable which you are attempting to run from cmd.exe then you need to tell cmd.exe where this file is located. There are 2 ways of doing this.

1. specify the full path to the file.

   "C:\My_Files\mycommand.exe"

2. Add the location of the file to your environment Variables.

Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables

In the System Variables Window, locate path and select edit

Now simply add your path to the end of the string, seperated by a semicolon ; as:

;C:\My_Files\

Save the changes and exit. You need to make sure that ANY cmd.exe windows you had open are then closed and re-opened to allow it to re-import the environment variables. Now you should be able to run mycommand.exe from any path, within cmd.exe as the environment is aware of the path to it.

When C:\Program or Similar fails

This is a very simple error. Each string after a white space is seen as a different command in cmd.exe terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe to see it as a single string, and not separate commands.

So to execute C:\Program Files\My-App\Mobile.exe simply run as:

"C:\Program Files\My-App\Mobile.exe"

Try this:

sys.getsizeof(object)

getsizeof() Return the size of an object in bytes. It calls the object’s __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.

A recursive recipe

Some tslint rules are disabling use of [], example message: Array type using 'T[]' is forbidden for non-simple types. Use 'Array<T>' instead.

Then you would write it like:

var userTestStatus: Array<{ id: number, name: string }> = Array(
    { "id": 0, "name": "Available" },
    { "id": 1, "name": "Ready" },
    { "id": 2, "name": "Started" }
);

android:layout_gravity="center"

or

android:gravity="center"

both works for me.

You should never use select(), or text(), or radio() etc.; it's terrible practice. You should use input():

$form->input('tree_id', array('options' => $trees));

Then in the controller:

$this->data['Leaf']['tree_id'] = $id;

As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined keyword.

tasks:
    - shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
      when: foo is defined

    - fail: msg="Bailing out. this play requires 'bar'"
      when: bar is undefined

Ansible Documentation

Below shows the query for mongoose's findOneAndUpdate. Here new: true is used to get the updated doc and fields is used for specific fields to get.

eg. findOneAndUpdate(conditions, update, options, callback)

await User.findOneAndUpdate({
      "_id": data.id,
    }, { $set: { name: "Amar", designation: "Software Developer" } }, {
      new: true,
      fields: {
        'name': 1,
        'designation': 1
      }
    }).exec();

I am using this, try it in playground. Define the base urls as Struct in Constants

struct Constants {

    struct APIDetails {
        static let APIScheme = "https"
        static let APIHost = "restcountries.eu"
        static let APIPath = "/rest/v1/alpha/"
    }
}

private func createURLFromParameters(parameters: [String:Any], pathparam: String?) -> URL {

    var components = URLComponents()
    components.scheme = Constants.APIDetails.APIScheme
    components.host   = Constants.APIDetails.APIHost
    components.path   = Constants.APIDetails.APIPath
    if let paramPath = pathparam {
        components.path = Constants.APIDetails.APIPath + "\(paramPath)"
    }
    if !parameters.isEmpty {
        components.queryItems = [URLQueryItem]()
        for (key, value) in parameters {
            let queryItem = URLQueryItem(name: key, value: "\(value)")
            components.queryItems!.append(queryItem)
        }
    }

    return components.url!
}

let url = createURLFromParameters(parameters: ["fullText" : "true"], pathparam: "IN")

//Result url= https://restcountries.eu/rest/v1/alpha/IN?fullText=true

This GitPro page does summarize the consequence of a git submodule update nicely

When you run git submodule update, it checks out the specific version of the project, but not within a branch. This is called having a detached head — it means the HEAD file points directly to a commit, not to a symbolic reference.
The issue is that you generally don’t want to work in a detached head environment, because it’s easy to lose changes.
If you do an initial submodule update, commit in that submodule directory without creating a branch to work in, and then run git submodule update again from the superproject without committing in the meantime, Git will overwrite your changes without telling you. Technically you won’t lose the work, but you won’t have a branch pointing to it, so it will be somewhat difficult to retrieve.

Note March 2013:

As mentioned in "git submodule tracking latest", a submodule now (git1.8.2) can track a branch.

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 
# or (with rebase)
git submodule update --rebase --remote

See "git submodule update --remote vs git pull".

MindTooth's answer illustrate a manual update (without local configuration):

git submodule -q foreach git pull -q origin master

In both cases, that will change the submodules references (the gitlink, a special entry in the parent repo index), and you will need to add, commit and push said references from the main repo.
Next time you will clone that parent repo, it will populate the submodules to reflect those new SHA1 references.

The rest of this answer details the classic submodule feature (reference to a fixed commit, which is the all point behind the notion of a submodule).

To avoid this issue, create a branch when you work in a submodule directory with git checkout -b work or something equivalent. When you do the submodule update a second time, it will still revert your work, but at least you have a pointer to get back to.

Switching branches with submodules in them can also be tricky. If you create a new branch, add a submodule there, and then switch back to a branch without that submodule, you still have the submodule directory as an untracked directory:

So, to answer your questions:

can I create branches/modifications and use push/pull just like I would in regular repos, or are there things to be cautious about?

You can create a branch and push modifications.

WARNING (from Git Submodule Tutorial): Always publish (push) the submodule change before publishing (push) the change to the superproject that references it. If you forget to publish the submodule change, others won't be able to clone the repository.

how would I advance the submodule referenced commit from say (tagged) 1.0 to 1.1 (even though the head of the original repo is already at 2.0)

The page "Understanding Submodules" can help

Git submodules are implemented using two moving parts:

• the .gitmodules file and
• a special kind of tree object.

These together triangulate a specific revision of a specific repository which is checked out into a specific location in your project.

From the git submodule page

you cannot modify the contents of the submodule from within the main project

100% correct: you cannot modify a submodule, only refer to one of its commits.

This is why, when you do modify a submodule from within the main project, you:

• need to commit and push within the submodule (to the upstream module), and
• then go up in your main project, and re-commit (in order for that main project to refer to the new submodule commit you just created and pushed)

A submodule enables you to have a component-based approach development, where the main project only refers to specific commits of other components (here "other Git repositories declared as sub-modules").

A submodule is a marker (commit) to another Git repository which is not bound by the main project development cycle: it (the "other" Git repo) can evolves independently.
It is up to the main project to pick from that other repo whatever commit it needs.

However, should you want to, out of convenience, modify one of those submodules directly from your main project, Git allows you to do that, provided you first publish those submodule modifications to its original Git repo, and then commit your main project refering to a new version of said submodule.

But the main idea remains: referencing specific components which:

• have their own lifecycle
• have their own set of tags
• have their own development

The list of specific commits you are refering to in your main project defines your configuration (this is what Configuration Management is all about, englobing mere Version Control System)

If a component could really be developed at the same time as your main project (because any modification on the main project would involve modifying the sub-directory, and vice-versa), then it would be a "submodule" no more, but a subtree merge (also presented in the question Transferring legacy code base from cvs to distributed repository), linking the history of the two Git repo together.

Does that help understanding the true nature of Git Submodules?

if you want to hide a whole div from the view in another screen size. You can follow bellow code as an example.

div.disabled{
  display: none;
}

try

$('#page_output').html(str_output);

Sadly, I experienced a case of multiple dots on file name that splittext does not worked well... my work around:

file = r'C:\Docs\file.2020.1.1.xls'
ext = '.'+ os.path.realpath(file).split('.')[-1:][0]
filefinal = file.replace(ext,'.zip')
os.rename(file ,filefinal)

This code actually doesn't provide focus:

new Actions(driver).moveToElement(element).perform();

It provides a hover effect.

Additionally, the JS code .focus() requires that the window be active in order to work.

js.executeScript("element.focus();");

I have found that this code works:

element.sendKeys(Keys.SHIFT);

For my own code, I use both:

element.sendKeys(Keys.SHIFT);
js.executeScript("element.focus();");

It's faster to avoid using regular expressions, if you're just trying to find the first substring match within an array of string values. You can add your own array searching function:

Code:

Array.prototype.findFirstSubstring = function(s) {
            for(var i = 0; i < this.length;i++)
            {
                if(this[i].indexOf(s) !== -1)
                    return i;
            }
            return -1;
        };

Usage:

i.findFirstSubstring('height');

Returns:

-1 if not found or the array index of the first substring occurrence if it is found (in your case would be 2)

From the screenshot I can see that you want to pass "user" and "password" values to the service. You have send the parameter values in the request header part which is wrong. The values are sent in the request body and not in the request header. Also your syntax is wrong. Correct syntax is: {"user":"user_val","password":"password_val"}. Also check what is the the content type. It should match with the content type you have set to your service.

You need to specify how you'll authenticate with the database. If you want to use integrated security (this means using Windows authentication using your local or domain Windows account), add this to the connection string:

Integrated Security = True;

If you want to use SQL Server authentication (meaning you specify a login and password rather than using a Windows account), add this:

User ID = "username"; Password = "password";

Apache Http Client APIs are very commonly used for calling HTTP Rest services.

Here is one of example of consuming HTTP GET call.

import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.impl.client.HttpClientBuilder;

public class CallHTTPGetService {

public static void main(String[] args) throws ClientProtocolException, IOException {


    HttpClient client = HttpClientBuilder.create().build();
    HttpUriRequest httpUriRequest = new HttpGet("URL");

    HttpResponse response = client.execute(httpUriRequest);
    System.out.println(response);

}
}

}   
}

To call it (from main):

mJSONParser = new JSONParser();
mJSONParser.execute();

I appreciate this might not be the answer to resolving on 3.4 but I tried a huge variety of things to fix this on 3.4 and thought this might be useful if someone is time pressed or doesn't have the know-how to correct it (in my case, work demands).

With exactly the same setup, I found that my installation problems only happened with Python 3.4. When I changed to 2.7, all my issues seemed to be resolved.

We have a rather overzealous security setup though so I'm going to try the same on my home version (still 3.4) and see if I have any more joy. My inclination is that my VS version has somehow been restricted and the answers above should help. If I find anything more tonight I'll add further detail.

This is my first reply, not the most technical I'm afraid!

A rather new project is the xml-coreutils package featuring xml-cat, xml-cp, xml-cut, xml-grep, ...

http://xml-coreutils.sourceforge.net/contents.html

What about creating an additional wrapper class?

package com.naveen.research.sql;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public abstract class PreparedStatementWrapper implements AutoCloseable {

    protected PreparedStatement stat;

    public PreparedStatementWrapper(Connection con, String query, Object ... params) throws SQLException {
        this.stat = con.prepareStatement(query);
        this.prepareStatement(params);
    }

    protected abstract void prepareStatement(Object ... params) throws SQLException;

    public ResultSet executeQuery() throws SQLException {
        return this.stat.executeQuery();
    }

    public int executeUpdate() throws SQLException {
        return this.stat.executeUpdate();
    }

    @Override
    public void close() {
        try {
            this.stat.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Then in the calling class you can implement prepareStatement method as:

try (Connection con = DriverManager.getConnection(JDBC_URL, prop);
    PreparedStatementWrapper stat = new PreparedStatementWrapper(con, query,
                new Object[] { 123L, "TEST" }) {
            @Override
            protected void prepareStatement(Object... params) throws SQLException {
                stat.setLong(1, Long.class.cast(params[0]));
                stat.setString(2, String.valueOf(params[1]));
            }
        };
        ResultSet rs = stat.executeQuery();) {
    while (rs.next())
        System.out.println(String.format("%s, %s", rs.getString(2), rs.getString(1)));
} catch (SQLException e) {
    e.printStackTrace();
}

In windows this scenario happens when Eclipse crashes without a clean shutdown it will have the local Jetty or Tomcat server keep running. When you reopen Eclipse and try to start server again this will lead to the "Address already in use: JVM_Bind"

You can solve this by opening Task Manager and find the javaw.exe process and ending it.

Then you can restart the server on Eclipse.

The compiler only knows that the code is or isn't reachable if you use "return". Think of Environment.Exit() as a function that you call, and the compiler don't know that it will close the application.

There is nothing like session container , so you can set it as null

but rather you can set individual session element as null or ""

like Session["userid"] = null;

Once you are in terminal/command line, access the database/collection you want to use as follows:

show dbs
use <db name>
show collections

choose your collection and type the following to see all contents of that collection:

db.collectionName.find()

More info here on the MongoDB Quick Reference Guide.

For me, it was like this using property

    let blueKills = match.blueTeam.participants.reduce(0, { (result, participant) -> Int in
        result + participant.kills
    })

String [] both = new ArrayList<String>(){{addAll(Arrays.asList(first)); addAll(Arrays.asList(second));}}.toArray(new String[0]);

If you have cloned your repo using url that contains your username, then you should also change remote.origin.url property because otherwise it keeps asking password for the old username.

example:

remote.origin.url=https://<old_uname>@<repo_url>

should change to

remote.origin.url=https://<new_uname>@<repo_url>

i'd suggest adding a class to display/hide elements:

.hide { display:none; }

and then use jquery's .toggleClass() to show/hide the element:

$(".news").toggleClass("hide");

I think op wants to know what the font that is used on a webpage is, and hoped that info might be findable in the 'inspect' pane.

Try adding the Whatfont Chrome extension.

I had this:

class paulzSprite;
...

struct spriteFrame
{
    spriteFrame(int, int, paulzSprite*, int, int);
    paulzSprite* pSprite; //points to the sprite class this struct frames
    static paulzSprite* pErase; //pointer to blanking sprite
    int x, y;
    int Xmin, Xmax, Ymin, Ymax; //limits, leave these to individual child classes, according to bitmap size
    bool move(int, int);
    bool DrawAt(int, int);
    bool dead;
};

spriteFrame::spriteFrame(int initx, int inity, paulzSprite* pSpr, int winWidth, int winHeight)
{
    x = initx;
    y= inity;
    pSprite = pSpr;
    Xmin = Ymin = 0;
    Xmax = winWidth - pSpr->width;
    Ymax = winHeight - pSpr->height;
    dead = false;
}

...

Got the same grief as in the original question. Only solved by moving the definition of paulzSprite to after that of spriteFrame. Shouldn't the compiler be smarter than this (VC++, VS 11 Beta)?

And btw, I wholeheartedly agree with Clifford's remark above "Pointers don't cause memory leaks, poor coding causes memory leaks". IMHO this is true of many other new "smart coding" features, which should not become a substitute for understanding what you are actually asking the computer to do.

I detected another reason - Thumbs.db, which affected performance badly.

Go to File > Settings > Editor > File Types and in field Ignore files and folders add this: Thumbs.db;

Now, Android Studio runs like a charm.

This solution worked for me.

The problem with setting location.hash is that the page will jump to that id if it's found on the page.

The problem with window.history.pushState is that it adds an entry to the history for each tab the user clicks. Then when the user clicks the back button, they go to the previous tab. (this may or may not be what you want. it was not what I wanted).

For me, replaceState was the better option in that it only replaces the current history, so when the user clicks the back button, they go to the previous page.

$('#tab-selector').tabs({
  activate: function(e, ui) {
    window.history.replaceState(null, null, ui.newPanel.selector);
  }
});

Check out the History API docs on MDN.

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

With jquery

  $("div#id").append('<a href=#>Your LINK TITLE</a>')

With javascript

   var new_a = document.createElement('a');
   new_a.setAttribute("href", "link url here");
   new_a.innerHTML = "your link text";
   //add new link to the DOM
   document.appendChild(new_a);

I solved my issue by editing the Bootstrap CSS file, see their doc:

.hide:

.hide is available, but it does not always affect screen readers and is deprecated as of v3.0.1

.hide {
  display: none !important;
}

.hidden is what we're suppose to use now, but it is actually:

.hidden {
  display: none !important;
  visibility: hidden !important;
}

The jQuery "fadeIn" won't work because of the "visibility".

So, for the latest Bootstrap, .hide is no longer in use, but it's still in the min.css file. so I left .hidden AS IS and just removed the "!important" from the ".hide" class ( which is supposed to be deprecated anyway ). but you can also just override it in your own CSS, I just wanted all my application to act the same so I changed the Bootstrap CSS file.

And now the jQuery "fadeIn()" works.

The reason that I've done this vs the suggestions above, is because when you "removeClass('.hide')" the object immediately is shown, and you skip the animation :)

I hope it helped others.

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')

Note that the value returned by the stored procedure is being return into :Z

You can either cast Height as a decimal:

select cast(@height as decimal(10, 5))/10 as heightdecimal

or you place a decimal point in your value you are dividing by:

declare @height int
set @height = 1023

select @height/10.0 as heightdecimal

see sqlfiddle with an example

ListBoxItem is a WPF class, NOT a WinForms class.

For WPF, use ListBoxItem.

For WinForms, the item is a Object type, so use one of these:
1. Provide your own ToString() method for the Object type.
2. Use databinding with DisplayMemeber and ValueMember (see Kelsey's answer)

I'm not quite sure what your problem is, but you need to specify the parameter name like so.

-(void) changeCellText:(NSIndexPath *) nowIndex{
    UILabel *content = (UILabel *)[[(UITableViewCell *)[(UITableView *)self cellForRowAtIndexPath:nowIndex] contentView] viewWithTag:contentTag];
    content.text = [formatter stringFromDate:checkInDate.date];
}

I downloaded and extracted Crypto++ in C:\cryptopp. I used Visual Studio Express 2012 to build all the projects inside (as instructed in readme), and everything was built successfully. Then I made a test project in some other folder and added cryptolib as a dependency.

The conversion was probably not successful. The only thing that was successful was the running of VCUpgrade. The actual conversion itself failed but you don't know until you experience the errors you are seeing. For some of the details, see Visual Studio on the Crypto++ wiki.

Any ideas how to fix this?

To resolve your issues, you should download vs2010.zip if you want static C/C++ runtime linking (/MT or /MTd), or vs2010-dynamic.zip if you want dynamic C/C++ runtime linking (/MT or /MTd). Both fix the latent, silent failures produced by VCUpgrade.

vs2010.zip, vs2010-dynamic.zip and vs2005-dynamic.zip are built from the latest GitHub sources. As of this writing (JUN 1 2016), that's effectively pre-Crypto++ 5.6.4. If you are using the ZIP files with a down level Crypto++, like 5.6.2 or 5.6.3, then you will run into minor problems.

There are two minor problems I am aware. First is a rename of bench.cpp to bench1.cpp. Its error is either:

• C1083: Cannot open source file: 'bench1.cpp': No such file or directory
• LNK2001: unresolved external symbol "void __cdecl OutputResultOperations(char const *,char const *,bool,unsigned long,double)" (?OutputResultOperations@@YAXPBD0_NKN@Z)

The fix is to either (1) open cryptest.vcxproj in notepad, find bench1.cpp, and then rename it to bench.cpp. Or (2) rename bench.cpp to bench1.cpp on the filesystem. Please don't delete this file.

The second problem is a little trickier because its a moving target. Down level releases, like 5.6.2 or 5.6.3, are missing the latest classes available in GitHub. The missing class files include HKDF (5.6.3), RDRAND (5.6.3), RDSEED (5.6.3), ChaCha (5.6.4), BLAKE2 (5.6.4), Poly1305 (5.6.4), etc.

The fix is to remove the missing source files from the Visual Studio project files since they don't exist for the down level releases.

Another option is to add the missing class files from the latest sources, but there could be complications. For example, many of the sources subtly depend upon the latest config.h, cpu.h and cpu.cpp. The "subtlety" is you won't realize you are getting an under-performing class.

An example of under-performing class is BLAKE2. config.h adds compile time ARM-32 and ARM-64 detection. cpu.h and cpu.cpp adds runtime ARM instruction detection, which depends upon compile time detection. If you add BLAKE2 without the other files, then none of the detection occurs and you get a straight C/C++ implementation. You probably won't realize you are missing the NEON opportunity, which runs around 9 to 12 cycles-per-byte versus 40 cycles-per-byte or so for vanilla C/C++.

This will work!

$(document).ready(function ()
    {
        $.ajax(
            {
            type: 'POST',
            url: "/Home/MethodName",
            success: function (data) {
                //data is the string that the method returns in a json format, but in string
                var jsonData = JSON.parse(data); //This converts the string to json

                for (var i = 0; i < jsonData.length; i++) //The json object has lenght
                {
                    var object = jsonData[i]; //You are in the current object
                    $('#olListId').append('<li class="someclass>' + object.Atributte  + '</li>'); //now you access the property.

                }

                /* JSON EXAMPLE
                [{ "Atributte": "value" }, 
                { "Atributte": "value" }, 
                { "Atributte": "value" }]
                */
            }
        });
    });

The main thing about this is using the property exactly the same as the attribute of the JSON key-value pair.

Use Pre-request script tab to write javascript to get and save the date into a variable:

const dateNow= new Date();
pm.environment.set('currentDate', dateNow.toISOString());

and then use it in the request body as follows:

"currentDate": "{{currentDate}}"

There is no real need to create a war to run it from Tomcat. You can follow these steps

1. Create a folder in webapps folder e.g. MyApp

2. Put your html and css in that folder and name the html file, which you want to be the starting page for your application, index.html

3. Start tomcat and point your browser to url "http://localhost:8080/MyApp". Your index.html page will pop up in the browser

Like this:

$dd = document.getElementById("yourselectelementid");
$so = $dd.options[$dd.selectedIndex];

Rewrite rules are pretty much written the same way with nginx: http://wiki.nginx.org/HttpRewriteModule#rewrite

Which rules are causing you trouble? I could help you translate those!

There are two parts to that answer (I wrote it). One part is easy to quantify, the other is more empirical.

Hardware Constraints:

This is the easy to quantify part. Appendix F of the current CUDA programming guide lists a number of hard limits which limit how many threads per block a kernel launch can have. If you exceed any of these, your kernel will never run. They can be roughly summarized as:

1. Each block cannot have more than 512/1024 threads in total (Compute Capability 1.x or 2.x and later respectively)
2. The maximum dimensions of each block are limited to [512,512,64]/[1024,1024,64] (Compute 1.x/2.x or later)
3. Each block cannot consume more than 8k/16k/32k/64k/32k/64k/32k/64k/32k/64k registers total (Compute 1.0,1.1/1.2,1.3/2.x-/3.0/3.2/3.5-5.2/5.3/6-6.1/6.2/7.0)
4. Each block cannot consume more than 16kb/48kb/96kb of shared memory (Compute 1.x/2.x-6.2/7.0)

If you stay within those limits, any kernel you can successfully compile will launch without error.

Performance Tuning:

This is the empirical part. The number of threads per block you choose within the hardware constraints outlined above can and does effect the performance of code running on the hardware. How each code behaves will be different and the only real way to quantify it is by careful benchmarking and profiling. But again, very roughly summarized:

1. The number of threads per block should be a round multiple of the warp size, which is 32 on all current hardware.
2. Each streaming multiprocessor unit on the GPU must have enough active warps to sufficiently hide all of the different memory and instruction pipeline latency of the architecture and achieve maximum throughput. The orthodox approach here is to try achieving optimal hardware occupancy (what Roger Dahl's answer is referring to).

The second point is a huge topic which I doubt anyone is going to try and cover it in a single StackOverflow answer. There are people writing PhD theses around the quantitative analysis of aspects of the problem (see this presentation by Vasily Volkov from UC Berkley and this paper by Henry Wong from the University of Toronto for examples of how complex the question really is).

At the entry level, you should mostly be aware that the block size you choose (within the range of legal block sizes defined by the constraints above) can and does have a impact on how fast your code will run, but it depends on the hardware you have and the code you are running. By benchmarking, you will probably find that most non-trivial code has a "sweet spot" in the 128-512 threads per block range, but it will require some analysis on your part to find where that is. The good news is that because you are working in multiples of the warp size, the search space is very finite and the best configuration for a given piece of code relatively easy to find.

For the record, this is documented in How do I add resources to my JAR? (illustrated for unit tests but the same applies for a "regular" resource):

To add resources to the classpath for your unit tests, you follow the same pattern as you do for adding resources to the JAR except the directory you place resources in is ${basedir}/src/test/resources. At this point you would have a project directory structure that would look like the following:

my-app
|-- pom.xml
`-- src
    |-- main
    |   |-- java
    |   |   `-- com
    |   |       `-- mycompany
    |   |           `-- app
    |   |               `-- App.java
    |   `-- resources
    |       `-- META-INF
    |           |-- application.properties
    `-- test
        |-- java
        |   `-- com
        |       `-- mycompany
        |           `-- app
        |               `-- AppTest.java
        `-- resources
            `-- test.properties

In a unit test you could use a simple snippet of code like the following to access the resource required for testing:

...

// Retrieve resource
InputStream is = getClass().getResourceAsStream("/test.properties" );

// Do something with the resource

...

I like to have a method in my activity called showToast which I can call from anywhere...

public void showToast(final String toast)
{
    runOnUiThread(() -> Toast.makeText(MyActivity.this, toast, Toast.LENGTH_SHORT).show());
}

I then most frequently call it from within MyActivity on any thread like this...

showToast(getString(R.string.MyMessage));

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

Also you can have the selected value using following code:

alert("Selected option value is: "+$('#SelectelementId').select2("val"));

A good bet is to utilize Rails' Arel SQL manager, which explicitly supports case-insensitive ActiveRecord queries:

t = Guide.arel_table Guide.where(t[:title].matches('%attack')) 

Here's an interesting blog post regarding the portability of case-insensitive queries using Arel. It's worth a read to understand the implications of utilizing Arel across databases.

Please check the following file

%SystemRoot%\system32\drivers\etc\host

The line which bind the host name with ip is probably missing a line which bind them togather

127.0.0.1  localhost

If the given line is missing. Add the line in the file

Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.

Add the column and update all rows in the DataTable, for example:

DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("ID", typeof(Int32)));
tbl.Columns.Add(new DataColumn("Name", typeof(string)));
for (Int32 i = 1; i <= 10; i++) {
    DataRow row = tbl.NewRow();
    row["ID"] = i;
    row["Name"] = i + ". row";
    tbl.Rows.Add(row);
}
DataColumn newCol = new DataColumn("NewColumn", typeof(string));
newCol.AllowDBNull = true;
tbl.Columns.Add(newCol);
foreach (DataRow row in tbl.Rows) {
    row["NewColumn"] = "You DropDownList value";
}
//if you don't want to allow null-values'
newCol.AllowDBNull = false;

Just use

<input type="number" id="foo" runat="server" />

It'll work on all modern browsers except IE +10. Here is a full list:

http://caniuse.com/#feat=input-number

Most importantly you need to mount the drive

net use z: \\yourserver\sharename

Of course, you need to make sure that the account the batch file runs under has permission to access the share. If you are doing this by using a Scheduled Task, you can choose the account by selecting the task, then:

• right click Properties
• click on General tab
• change account under

"When running the task, use the following user account:" That's on Windows 7, it might be slightly different on different versions of Windows.

Then run your batch script with the following changes

copy "z:\FolderName" "C:\TEST_BACKUP_FOLDER"

if the file containing that link tag is in the root dir of the project, then the correct path would be "css/styles.css"

You can limit mongod process usage using cgroups on Linux.

Using cgroups, our task can be accomplished in a few easy steps.

1. Create control group:

   cgcreate -g memory:DBLimitedGroup 
   

   (make sure that cgroups binaries installed on your system, consult your favorite Linux distribution manual for how to do that)

2. Specify how much memory will be available for this group:

   echo 16G > /sys/fs/cgroup/memory/DBLimitedGroup/memory.limit_in_bytes
   

   This command limits memory to 16G (good thing this limits the memory for both malloc allocations and OS cache)

3. Now, it will be a good idea to drop pages already stayed in cache:

   sync; echo 3 > /proc/sys/vm/drop_caches
   

4. And finally assign a server to created control group:

   cgclassify -g memory:DBLimitedGroup \`pidof mongod\`
   

   This will assign a running mongod process to a group limited by only 16GB memory.

source: Using Cgroups to Limit MySQL and MongoDB memory usage

simple just run

rm -r node_modules

in fact, you can delete any folder with this.

like rm -r AnyFolderWhichIsNotDeletableFromShiftDeleteOrDelete.

just open the gitbash move to root of the folder and run this command

Hope this will help.

There are some great, articulate answers already, but the question asks for a random number between 0 and 74. Use:

arc4random_uniform(75)

For me it worked after manually copying the sqljdbc4-2.jar into WEB-INF/lib folder. So please have a try on this too.

Pass the id and hold into a variable and pass the variable where ever you want.

var temp = $('select[name=ID Name]').val();

Let's not use NOW() as you're losing any query caching or optimization because the query is different every time. See the list of functions you should not use in the MySQL documentation.

In the code below, let's assume this table is growing with time. New stuff is added and you want to show just the stuff in the last 30 days. This is the most common case.

Note that the date has been added as a string. It is better to add the date in this way, from your calling code, than to use the NOW() function as it kills your caching.

SELECT * FROM table WHERE exec_datetime >= DATE_SUB('2012-06-12', INTERVAL 30 DAY);

You can use BETWEEN if you really just want stuff from this very second to 30 days before this very second, but that's not a common use case in my experience, so I hope the simplified query can serve you well.

Return 0 on success and non-zero for error. This is the standard used by UNIX and DOS scripting to find out what happened with your program.

While looping through your string one character at a time is a viable method, there's no need. VBA has built-in functions for this kind of thing:

Public Function ProcessString(input_string As String) As String
    ProcessString=Replace(input_string,"*","")
End Function

On my Ubuntu 13.04, I tried quite a few tweaks before succeeding with this:

1. Edit /etc/init/jenkins.conf
2. Locate the spot where "exec start-stop-server..." begins
3. Insert the environment update just before that, i.e.

export PATH=$PATH:/some/new/path/bin

Simple solution: IN ~/.sdkman/etc/config, change sdkman_insecure_ssl=true

Steps:
nano ~/.sdkman/etc/config
change sdkman_insecure_ssl=false to sdkman_insecure_ssl=true
save and exit

You can use a Union.

This will return the results of the queries in separate rows.

First you must make sure that both queries return identical columns.

Then you can do :

SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS Number
FROM tableD 
RIGHT OUTER JOIN [tableB] 
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id 
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

UNION

SELECT tableA.Id, tableA.Name,  '' AS Owner, '' AS ImageUrl, '' AS CompanyImageUrl, COUNT([tableC].Id) AS Number
FROM 
[tableC] 
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id GROUP BY tableA.Id, tableA.Name

As has been mentioned, both queries return quite different data. You would probably only want to do this if both queries return data that could be considered similar.

SO

You can use a Join

If there is some data that is shared between the two queries. This will put the results of both queries into a single row joined by the id, which is probably more what you want to be doing here...

You could do :

SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS NumberOfUsers, query2.NumberOfPlans
FROM tableD 
RIGHT OUTER JOIN [tableB] 
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id 


INNER JOIN 
  (SELECT tableA.Id, COUNT([tableC].Id) AS NumberOfPlans 
   FROM [tableC] 
   RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id 
   GROUP BY tableA.Id, tableA.Name) AS query2 
ON query2.Id = tableA.Id

GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

Did you know that JavaScript has it's built-in methods and libs to create forms and submit them?

I am seeing a lot of replies here all asking to use a 3rd party library which I think is an overkill.

I would do the following in pure Javascript:

<script>
function launchMyForm()
{
   var myForm = document.createElement("FORM");
   myForm.setAttribute("id","TestForm");
   document.body.appendChild(myForm);

// this will create a new FORM which is mapped to the Java Object of myForm, with an id of TestForm. Equivalent to: <form id="TestForm"></form>

   var myInput = document.createElement("INPUT");
   myInput.setAttribute("id","MyInput");
   myInput.setAttribute("type","text");
   myInput.setAttribute("value","Heider");
   document.getElementById("TestForm").appendChild(myInput);

// This will create an INPUT equivalent to: <INPUT id="MyInput" type="text" value="Heider" /> and then assign it to be inside the TestForm tags. 
}
</script>

This way (A) you don't need to rely on 3rd parties to do the job. (B) It's all built-in to all browsers, (C) faster, (D) it works, feel free to try it out.

I hope this helps. H

If you in any doubt, have a look at JDK source code

ArrayList.clear() source code:

public void clear() {
    modCount++;

    // Let gc do its work
    for (int i = 0; i < size; i++)
        elementData[i] = null;

    size = 0;
}

You will see that size is set to 0 so you start from 0 position.

Please note that when adding elements to ArrayList, the backend array is extended (i.e. array data is copied to bigger array if needed) in order to be able to add new items. When performing ArrayList.clear() you only remove references to array elements and sets size to 0, however, capacity stays as it was.

This works for me:

public void updatedatabase()
{

    SqlConnection conn = new SqlConnection("Data Source=" + txtserver.Text.Trim() + ";Initial Catalog=" + txtdatabase.Text.Trim() + ";User ID=" + txtuserid.Text.Trim() + ";Password=" + txtpwd.Text.Trim() + "");
    try
    {

        conn.Open();

        string script = File.ReadAllText(Server.MapPath("~/Script/DatingDemo.sql"));

        // split script on GO command
        IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$", RegexOptions.Multiline | RegexOptions.IgnoreCase);
        foreach (string commandString in commandStrings)
        {
            if (commandString.Trim() != "")
            {
                new SqlCommand(commandString, conn).ExecuteNonQuery();
            }
        }
        lblmsg.Text = "Database updated successfully.";

    }
    catch (SqlException er)
    {
        lblmsg.Text = er.Message;
        lblmsg.ForeColor = Color.Red;
    }
    finally
    {
        conn.Close();
    }
}

$unixtime = 1307595105;
echo $time = date("m/d/Y h:i:s A T",$unixtime);

Besides the solutions presented already, you could use the Apache Commons Lang library:

if(StringUtils.startsWithAny(newStr4, new String[] {"Mon","Tues",...})) {
  //whatever
}

Update: the introduction of varargs at some point makes the call simpler now:

StringUtils.startsWithAny(newStr4, "Mon", "Tues",...)

It would have worked out of the box if you hadn't used @EnableWebMvc annotation. When you do that you switch off all the things that Spring Boot does for you in WebMvcAutoConfiguration. You could remove that annotation, or you could add back the view controller that you switched off:

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("forward:/index.html");
}

OP's problem was related with HTML coding. But if you are using plain text, please use "\n" and not "\r\n".

My personal use case: using mailx mailer, simply replacing "\r\n" into "\n" fixed my issue, related with wrong automatic Content-Type setting.

Wrong header:

User-Agent: Heirloom mailx 12.4 7/29/08
MIME-Version: 1.0
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64

Correct header:

User-Agent: Heirloom mailx 12.4 7/29/08
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I'm not saying that "application/octet-stream" and "base64" are always wrong/unwanted, but they where in my case.

A "rollback" only works if you used transactions. That way you can group queries together and undo all queries if only one of them fails.

But if you already committed the transaction (or used a regular DELETE-query), the only way of getting your data back is to recover it from a previously made backup.

There is also a new option now in http://vimr.org/, which looks quite promising.

If you can create your sql statement dynamically you can do following workaround:

String myArray[][] = { { "1-1", "1-2" }, { "2-1", "2-2" }, { "3-1", "3-2" } };

StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");

for (int i = 0; i < myArray.length - 1; i++) {
    mySql.append(", (?, ?)");
}

myStatement = myConnection.prepareStatement(mySql.toString());

for (int i = 0; i < myArray.length; i++) {
    myStatement.setString(i, myArray[i][1]);
    myStatement.setString(i, myArray[i][2]);
}
myStatement.executeUpdate();

Spring has a utility method for this:

TypedQuery<Profile> query = em.createNamedQuery(namedQuery, Profile.class);
...
return org.springframework.dao.support.DataAccessUtils.singleResult(query.getResultList());

If you are using a mouse first do

 :set paste 

Then right click mouse and the contents in buffer will be pasted

The answer of @DanielPlaisted before generally works, but the generic method must be public or one must use BindingFlags.NonPublic | BindingFlags.Instance! Couldn't post it as a comment for lack of reputation.

I just added that to the media object manually

let media = document.querySelector('.my-video');
media.isplaying = false;

...

if(media.isplaying) //do something

Then just toggle it when i hit play or pause.

Following the greenhoorn's answer, you can use "Extensions" like this:

  public static class HttpClientExtensions
    {
        public static HttpClient AddTokenToHeader(this HttpClient cl, string token)
        {
            //int timeoutSec = 90;
            //cl.Timeout = new TimeSpan(0, 0, timeoutSec);
            string contentType = "application/json";
            cl.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(contentType));
            cl.DefaultRequestHeaders.Add("Authorization", String.Format("Bearer {0}", token));
            var userAgent = "d-fens HttpClient";
            cl.DefaultRequestHeaders.Add("User-Agent", userAgent);
            return cl;
        }
    }

And use:

string _tokenUpdated = "TOKEN";
HttpClient _client;
_client.AddTokenToHeader(_tokenUpdated).GetAsync("/api/values")

This syntax has changed with the newer Apache HTTPd server, please see upgrade to apache 2.4 doc for full details.

2.2 configuration syntax was

Order deny,allow
Deny from all

2.4 configuration now is

Require all denied

Thus, this 2.2 syntax

order deny,allow
deny from all
allow from 127.0.0.1

Would ne now written

Require local

This may be obvious, but you can inline the array like so:

package main

import (
    "fmt"
)

func main() {
    for _, element := range [3]string{"a", "b", "c"} {
        fmt.Print(element)
    }
}

outputs:

abc

https://play.golang.org/p/gkKgF3y5nmt

var student = [];
var obj = {
    'first_name': name,
    'last_name': name,
    'age': age,
}
student.push(obj);

You can use publicPath to point to the location where you want webpack-dev-server to serve its "virtual" files. The publicPath option will be the same location of the content-build option for webpack-dev-server. webpack-dev-server creates virtual files that it will use when you start it. These virtual files resemble the actual bundled files webpack creates. Basically you will want the --content-base option to point to the directory your index.html is in. Here is an example setup:

//application directory structure
/app/
/build/
/build/index.html
/webpack.config.js


//webpack.config.js
var path = require("path");
module.exports = {
...
  output: {
    path: path.resolve(__dirname, "build"),
    publicPath: "/assets/",
    filename: "bundle.js"
  }
};  


//index.html
<!DOCTYPE>
<html>
...
<script src="assets/bundle.js"></script>
</html>

//starting a webpack-dev-server from the command line
$ webpack-dev-server --content-base build 

webpack-dev-server has created a virtual assets folder along with a virtual bundle.js file that it refers to. You can test this by going to localhost:8080/assets/bundle.js then check in your application for these files. They are only generated when you run the webpack-dev-server.

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

as date_format uses the same format as date ( http://www.php.net/manual/en/function.date.php ) the "Numeric representation of a month, without leading zeros" is a lowercase n .. so

echo date('n'); // "9"

Another approach is to use ForEach-Object to project individual items to a string and then use the Out-String CmdLet to project the final results to a string or string array:

gci Microsoft.PowerShell.Core\Registry::HKEY_CLASSES_ROOT\CID | foreach { "CID Key {0}" -f $_.Name } | Out-String

#Result: One multi-line string equal to:
@"
CID Key HKEY_CLASSES_ROOT\CID\2a621c8a-7d4b-4d7b-ad60-a957fd70b0d0
CID Key HKEY_CLASSES_ROOT\CID\2ec6f5b2-8cdc-461e-9157-ffa84c11ba7d
CID Key HKEY_CLASSES_ROOT\CID\5da2ceaf-bc35-46e0-aabd-bd826023359b
CID Key HKEY_CLASSES_ROOT\CID\d13ad82e-d4fb-495f-9b78-01d2946e6426
"@

gci Microsoft.PowerShell.Core\Registry::HKEY_CLASSES_ROOT\CID | foreach { "CID Key {0}" -f $_.Name } | Out-String -Stream

#Result: An array of single line strings equal to:
@(
"CID Key HKEY_CLASSES_ROOT\CID\2a621c8a-7d4b-4d7b-ad60-a957fd70b0d0",
"CID Key HKEY_CLASSES_ROOT\CID\2ec6f5b2-8cdc-461e-9157-ffa84c11ba7d",
"CID Key HKEY_CLASSES_ROOT\CID\5da2ceaf-bc35-46e0-aabd-bd826023359b",
"CID Key HKEY_CLASSES_ROOT\CID\d13ad82e-d4fb-495f-9b78-01d2946e6426")

The benefit of this approach is that you can store the result to a variable and it will NOT have any empty lines.

too late.. but I guess I have the answer -

Here's my sample study.df dataframe -

   >study.df
   study   sample       collection_dt other_column
   1 DS-111 ES768098 2019-01-21:04:00:30         <NA>

   3 DS-111 ES768100                <NA>   some_value

And then -

Use OnCommand event of imagebutton. Within it do

<asp:Button id="Button1" Text="Click" CommandName="Something" CommandArgument="your command arg" OnCommand="CommandBtn_Click" runat="server"/>

Code-behind:

void CommandBtn_Click(Object sender, CommandEventArgs e) 
{    
    switch(e.CommandName)
    {
        case "Something":
            // Do your code
            break;
        default:              
            break; 

    }
}

json.dumps() is much more than just making a string out of a Python object, it would always produce a valid JSON string (assuming everything inside the object is serializable) following the Type Conversion Table.

For instance, if one of the values is None, the str() would produce an invalid JSON which cannot be loaded:

>>> data = {'jsonKey': None}
>>> str(data)
"{'jsonKey': None}"
>>> json.loads(str(data))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)

But the dumps() would convert None into null making a valid JSON string that can be loaded:

>>> import json
>>> data = {'jsonKey': None}
>>> json.dumps(data)
'{"jsonKey": null}'
>>> json.loads(json.dumps(data))
{u'jsonKey': None}

You don't need jQuery, and there are a bunch of ways to do it, for example:

var parts = myString.split('/');
var answer = parts[parts.length - 1];

Where myString contains your string.

I am doing this way:

<div class="card-logo">
    <img height="100%" width="100%" src="http://someimage.jpg">
</div>

and CSS:

.card-logo {
    width: 20%;
}

I prefer this way, as if I need to upscale - I can use 150% as well

There's now a full-fledged plugin for that:

Had similar problems recently. Would suggest you carefully check if the user you're connecting with has proper authorizations on the remote machine.

You can review permissions using the following command.

Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell

Found this tip here (updated link, thanks "unbob"):

https://devblogs.microsoft.com/scripting/configure-remote-security-settings-for-windows-powershell/

It fixed it for me.

For Java 1.8 and higher you must set -Djdk.http.auth.tunneling.disabledSchemes= to make proxies with Basic Authorization working with https.

Well You see.. SOA stands for Service Oriented Architecture.... In simplest words, you write a piece of code that is very generic i.e. it does some thing that can be used in a lot of applications ... may be something like a address book or may be a calculator. and you launch this code on the IIS. So you provide a service through your code. So you are a service provider. Now someone wants to use a similar code then he does not have to write the code again. He simply uses your code maybe through a web service. Hence he becomes a service consumer. Hence making a program using such services is called SOA. And the loose coupling is there as the service provider and consumer may be interacting even if they are using diff programming languages. Hope you understand.

You can control the default behavior by setting push.default in your git config. From the git-config(1) documentation:

push.default

Defines the action git push should take if no refspec is given on the command line, no refspec is configured in the remote, and no refspec is implied by any of the options given on the command line. Possible values are:

• nothing: do not push anything

• matching: push all matching branches

  All branches having the same name in both ends are considered to be matching.

  This used to be the default, but not since Git 2.0 (simple is the new default).

• upstream: push the current branch to its upstream branch (tracking is a deprecated synonym for upstream)

• current: push the current branch to a branch of the same name

• simple: (new in Git 1.7.11) like upstream, but refuses to push if the upstream branch's name is different from the local one

  This is the safest option and is well-suited for beginners.

  This mode has become the default in Git 2.0.

The simple, current and upstream modes are for those who want to push out a single branch after finishing work, even when the other branches are not yet ready to be pushed out

Command line examples:

To view the current configuration:

git config --global push.default

To set a new configuration:

git config --global push.default current

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }

Here is a "concrete" (and possibly useful) example of how, why, and when to use these handy, yet unsightly constructs...

Xcode uses a "global" "user default" to decide which XCTestObserver class spews it's heart out to the beleaguered console.

In this example... when I implicitly load this psuedo-library, let's call it... libdemure.a, via a flag in my test target á la..

OTHER_LDFLAGS = -ldemure

I want to..

1. At load (ie. when XCTest loads my test bundle), override the "default" XCTest "observer" class... (via the constructor function) PS: As far as I can tell.. anything done here could be done with equivalent effect inside my class' + (void) load { ... } method.

2. run my tests.... in this case, with less inane verbosity in the logs (implementation upon request)

3. Return the "global" XCTestObserver class to it's pristine state.. so as not to foul up other XCTest runs which haven't gotten on the bandwagon (aka. linked to libdemure.a). I guess this historically was done in dealloc.. but I'm not about to start messing with that old hag.

So...

#define USER_DEFS NSUserDefaults.standardUserDefaults

@interface      DemureTestObserver : XCTestObserver @end
@implementation DemureTestObserver

__attribute__((constructor)) static void hijack_observer() {

/*! here I totally hijack the default logging, but you CAN
    use multiple observers, just CSV them, 
    i.e. "@"DemureTestObserverm,XCTestLog"
*/
  [USER_DEFS setObject:@"DemureTestObserver" 
                forKey:@"XCTestObserverClass"];
  [USER_DEFS synchronize];
}

__attribute__((destructor)) static void reset_observer()  {

  // Clean up, and it's as if we had never been here.
  [USER_DEFS setObject:@"XCTestLog" 
                forKey:@"XCTestObserverClass"];
  [USER_DEFS synchronize];
}

...
@end

Without the linker flag... (Fashion-police swarm Cupertino demanding retribution, yet Apple's default prevails, as is desired, here)

WITH the -ldemure.a linker flag... (Comprehensible results, gasp... "thanks constructor/destructor"... Crowd cheers)

If you use CSS to select a monospace font, the problem of varying character length is easily solved.

This code may be helpful for you.

from tkinter import filedialog
from tkinter import *
root = Tk()
root.withdraw()
folder_selected = filedialog.askdirectory()

Try this one if you are working with python 2.7:

from __future__ import print_function

You may use Upsert with $setOnInsert operator.

db.Table.update({noExist: true}, {"$setOnInsert": {xxxYourDocumentxxx}}, {upsert: true})

Another solution could be to use Number object parser like this:

let result = Number(new Date("2012-02-10T13:19:11+0000"));_x000D_
let resultWithGetTime = (new Date("2012-02-10T13:19:11+0000")).getTime();_x000D_
console.log(result);_x000D_
console.log(resultWithGetTime);

This converts to milliseconds just like getTime() on Date object

Since no answers were posted, I found the following here:

The Web server (running the Web site) thinks that the request submitted by the client (e.g. your Web browser or our CheckUpDown robot) can not be completed because it conflicts with some rule already established. For example, you may get a 409 error if you try to upload a file to the Web server which is older than the one already there - resulting in a version control conflict.

Someone on a similar question right here on stackoverflow, said the answer was:

I've had this issue when I was referencing the url of the document library and not the destination file itself.

i.e. try http://server name/document library name/new file name.doc

However I am 100% sure this was not my case, since I checked the WebRequest's URI property several times and the URI was complete with filename, and all the folders in the path existed on the sharepoint site.

Anyways, I hope this helps someone.

Probably my question should have been more specific. I actually know a base class for the string so solved it by:

ReportClass report = (ReportClass)Activator.CreateInstance(Type.GetType(reportClass));

The Activator.CreateInstance class has various methods to achieve the same thing in different ways. I could have cast it to an object but the above is of the most use to my situation.

You can use CTRL+R, CTRL+R or for complex namespace changes use this tool https://marketplace.visualstudio.com/items?itemName=vs-publisher-599079.FixNamespace

inserting data form one table to another table in different DATABASE

insert into DocTypeGroup 
    Select DocGrp_Id,DocGrp_SubId,DocGrp_GroupName,DocGrp_PM,DocGrp_DocType 
    from Opendatasource( 'SQLOLEDB','Data Source=10.132.20.19;UserID=sa;Password=gchaturthi').dbIPFMCI.dbo.DocTypeGroup

Lets say we have existing list, and gonna use java 8 for this activity `

import java.util.*;
import java.util.stream.Collectors;

public class AddingArray {

    public void addArrayInList(){
        List<Integer> list = Arrays.asList(3, 7, 9);

   // And we have an array of Integer type 

        int nums[] = {4, 6, 7};

   //Now lets add them all in list
   // converting array to a list through stream and adding that list to previous list
        list.addAll(Arrays.stream(nums).map(num -> 
                                       num).boxed().collect(Collectors.toList()));
     }
}

`

I just tried all of these, and for IE11, the only thing that seems to work is disabled="true". Values of disabled or no value given didnt work. As a matter of fact, the jsp got an error that equal is required for all fields, so I had to specify disabled="true" for this to work.

use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

The language specification says on p.64f

A construct of the form < T > ( ... ) => { ... } could be parsed as an arrow function expression with a type parameter or a type assertion applied to an arrow function with no type parameter. It is resolved as the former[..]

example:

// helper function needed because Backbone-couchdb's sync does not return a jqxhr
let fetched = <
           R extends Backbone.Collection<any> >(c:R) => {
               return new Promise(function (fulfill, reject) {
                   c.fetch({reset: true, success: fulfill, error: reject})
               });
           };

select ID from A where ID not in (select ID from B);

or

select ID from A except select ID from B;

Your second question:

delete from A where ID not in (select ID from B);

For the sake of completeness, here's another possible solution:

SELECT sensorID,timestamp,sensorField1,sensorField2 
FROM sensorTable s1
WHERE timestamp = (SELECT MAX(timestamp) FROM sensorTable s2 WHERE s1.sensorID = s2.sensorID)
ORDER BY sensorID, timestamp;

Pretty self-explaining I think, but here's more info if you wish, as well as other examples. It's from the MySQL manual, but above query works with every RDBMS (implementing the sql'92 standard).

I had trouble passing parameters to the Commands.AddScript method.

C:\Foo1.PS1 Hello World Hunger
C:\Foo2.PS1 Hello World

scriptFile = "C:\Foo1.PS1"

parameters = "parm1 parm2 parm3" ... variable length of params

I Resolved this by passing null as the name and the param as value into a collection of CommandParameters

Here is my function:

private static void RunPowershellScript(string scriptFile, string scriptParameters)
{
    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
    Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
    runspace.Open();
    RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
    Pipeline pipeline = runspace.CreatePipeline();
    Command scriptCommand = new Command(scriptFile);
    Collection<CommandParameter> commandParameters = new Collection<CommandParameter>();
    foreach (string scriptParameter in scriptParameters.Split(' '))
    {
        CommandParameter commandParm = new CommandParameter(null, scriptParameter);
        commandParameters.Add(commandParm);
        scriptCommand.Parameters.Add(commandParm);
    }
    pipeline.Commands.Add(scriptCommand);
    Collection<PSObject> psObjects;

The preferred way to specify toolchain-specific options is using CMake's toolchain facility. This ensures that there is a clean division between:

• instructions on how to organise source files into targets -- expressed in CMakeLists.txt files, entirely toolchain-agnostic; and
• details of how certain toolchains should be configured -- separated into CMake script files, extensible by future users of your project, scalable.

Ideally, there should be no compiler/linker flags in your CMakeLists.txt files -- even within if/endif blocks. And your program should build for the native platform with the default toolchain (e.g. GCC on GNU/Linux or MSVC on Windows) without any additional flags.

Steps to add a toolchain:

1. Create a file, e.g. arm-linux-androideadi-gcc.cmake with global toolchain settings:

   set(CMAKE_CXX_COMPILER arm-linux-gnueabihf-g++)
   set(CMAKE_CXX_FLAGS_INIT "-fexceptions")
   

   (You can find an example Linux cross-compiling toolchain file here.)

2. When you want to generate a build system with this toolchain, specify the CMAKE_TOOLCHAIN_FILE parameter on the command line:

   mkdir android-arm-build && cd android-arm-build
   cmake -DCMAKE_TOOLCHAIN_FILE=$(pwd)/../arm-linux-androideadi-gcc.cmake ..
   

   (Note: you cannot use a relative path.)

3. Build as normal:

   cmake --build .
   

Toolchain files make cross-compilation easier, but they have other uses:

• Hardened diagnostics for your unit tests.

  set(CMAKE_CXX_FLAGS_INIT "-Werror -Wall -Wextra -Wpedantic")
  

• Tricky-to-configure development tools.

  # toolchain file for use with gcov
  set(CMAKE_CXX_FLAGS_INIT "--coverage -fno-exceptions -g")
  

• Enhanced safety checks.

  # toolchain file for use with gdb
  set(CMAKE_CXX_FLAGS_DEBUG_INIT "-fsanitize=address,undefined -fsanitize-undefined-trap-on-error")
  set(CMAKE_EXE_LINKER_FLAGS_INIT "-fsanitize=address,undefined -static-libasan")
  

gpg: no valid OpenPGP data found.

In this scenario, the message is a cryptic way of telling you that the download failed. Piping these two steps together is nice when it works, but it kind of breaks the error reporting -- especially when you use wget -q (or curl -s), because these suppress error messages from the download step.

There could be any number of reasons for the download failure. My case, which wasn't exactly listed so far, was that the proxy settings were lost when I called the enclosing script with sudo.

Based on this questions answer I implemented a class you can use to read a file synchronously line-by-line with fs.readSync(). You can make this "pause" and "resume" by using a Q promise (jQuery seems to require a DOM so cant run it with nodejs):

var fs = require('fs');
var Q = require('q');

var lr = new LineReader(filenameToLoad);
lr.open();

var promise;
workOnLine = function () {
    var line = lr.readNextLine();
    promise = complexLineTransformation(line).then(
        function() {console.log('ok');workOnLine();},
        function() {console.log('error');}
    );
}
workOnLine();

complexLineTransformation = function (line) {
    var deferred = Q.defer();
    // ... async call goes here, in callback: deferred.resolve('done ok'); or deferred.reject(new Error(error));
    return deferred.promise;
}

function LineReader (filename) {      
  this.moreLinesAvailable = true;
  this.fd = undefined;
  this.bufferSize = 1024*1024;
  this.buffer = new Buffer(this.bufferSize);
  this.leftOver = '';

  this.read = undefined;
  this.idxStart = undefined;
  this.idx = undefined;

  this.lineNumber = 0;

  this._bundleOfLines = [];

  this.open = function() {
    this.fd = fs.openSync(filename, 'r');
  };

  this.readNextLine = function () {
    if (this._bundleOfLines.length === 0) {
      this._readNextBundleOfLines();
    }
    this.lineNumber++;
    var lineToReturn = this._bundleOfLines[0];
    this._bundleOfLines.splice(0, 1); // remove first element (pos, howmany)
    return lineToReturn;
  };

  this.getLineNumber = function() {
    return this.lineNumber;
  };

  this._readNextBundleOfLines = function() {
    var line = "";
    while ((this.read = fs.readSync(this.fd, this.buffer, 0, this.bufferSize, null)) !== 0) { // read next bytes until end of file
      this.leftOver += this.buffer.toString('utf8', 0, this.read); // append to leftOver
      this.idxStart = 0
      while ((this.idx = this.leftOver.indexOf("\n", this.idxStart)) !== -1) { // as long as there is a newline-char in leftOver
        line = this.leftOver.substring(this.idxStart, this.idx);
        this._bundleOfLines.push(line);        
        this.idxStart = this.idx + 1;
      }
      this.leftOver = this.leftOver.substring(this.idxStart);
      if (line !== "") {
        break;
      }
    }
  }; 
}

(ANSWER IS IN DOT NET 4.5 and in java, there must be a similar approach exist)

I am from West Bengal in INDIA. As I understand your problem is ... You want to produce similar to ' ? ' (It is a letter in Bengali language) which has Unicode HEX : 0X0985.

Now if you know this value in respect of your language then how will you produce that language specific Unicode symbol right ?

In Dot Net it is as simple as this :

int c = 0X0985;
string x = Char.ConvertFromUtf32(c);

Now x is your answer. But this is HEX by HEX convert and sentence to sentence conversion is a work for researchers :P

You can use the Y-combinator: (Wikipedia)

// ES5 syntax
var Y = function Y(a) {
  return (function (a) {
    return a(a);
  })(function (b) {
    return a(function (a) {
      return b(b)(a);
    });
  });
};

// ES6 syntax
const Y = a=>(a=>a(a))(b=>a(a=>b(b)(a)));

// If the function accepts more than one parameter:
const Y = a=>(a=>a(a))(b=>a((...a)=>b(b)(...a)));

And you can use it as this:

// ES5
var fn = Y(function(fn) {
  return function(counter) {
    console.log(counter);
    if (counter > 0) {
      fn(counter - 1);
    }
  }
});

// ES6
const fn = Y(fn => counter => {
  console.log(counter);
  if (counter > 0) {
    fn(counter - 1);
  }
});

You can implement like a below logic. Suppose you want an array of values.

let test = [ {name:'test',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:30},
             {name:'test3',lastname:'kumar',age:47},
             {name:'test',lastname:'kumar',age:28},
             {name:'test4',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:29}]

let result1 = test.map(element => 
              { 
                 if (element.age === 30) 
                 {
                    return element.lastname;
                 }
              }).filter(notUndefined => notUndefined !== undefined);

output : ['kumar','kumar','kumar']

Quoted from the javadoc;

This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class's natural ordering, and the class's compareTo method is referred to as its natural comparison method.

Lists (and arrays) of objects that implement this interface can be sorted automatically by Collections.sort (and Arrays.sort). Objects that implement this interface can be used as keys in a sorted map or as elements in a sorted set, without the need to specify a comparator.

Edit: ..and made the important bit bold.

This might help, I used to fi my files like this: http://security102.blogspot.ru/2010/04/findreplace-of-nul-objects-in-notepad.html

Basically you need to replace \x00 characters with regular expressions

myWebView.setAlpha(0);

is the best answer. It works!

If you are coming from Eclipse: http://tanu.wordpress.com/2010/09/24/moving-from-eclipse-to-intellij-idea/

General documentation and shortcuts are on Intellij's site http://www.jetbrains.com/idea/documentation/index.jsp

Just to expand on casperOne's answer.

The JSON spec does not account for Date values. MS had to make a call, and the path they chose was to exploit a little trick in the javascript representation of strings: the string literal "/" is the same as "\/", and a string literal will never get serialized to "\/" (even "\/" must be mapped to "\\/").

See http://msdn.microsoft.com/en-us/library/bb299886.aspx#intro_to_json_topic2 for a better explanation (scroll down to "From JavaScript Literals to JSON")

One of the sore points of JSON is the lack of a date/time literal. Many people are surprised and disappointed to learn this when they first encounter JSON. The simple explanation (consoling or not) for the absence of a date/time literal is that JavaScript never had one either: The support for date and time values in JavaScript is entirely provided through the Date object. Most applications using JSON as a data format, therefore, generally tend to use either a string or a number to express date and time values. If a string is used, you can generally expect it to be in the ISO 8601 format. If a number is used, instead, then the value is usually taken to mean the number of milliseconds in Universal Coordinated Time (UTC) since epoch, where epoch is defined as midnight January 1, 1970 (UTC). Again, this is a mere convention and not part of the JSON standard. If you are exchanging data with another application, you will need to check its documentation to see how it encodes date and time values within a JSON literal. For example, Microsoft's ASP.NET AJAX uses neither of the described conventions. Rather, it encodes .NET DateTime values as a JSON string, where the content of the string is /Date(ticks)/ and where ticks represents milliseconds since epoch (UTC). So November 29, 1989, 4:55:30 AM, in UTC is encoded as "\/Date(628318530718)\/".

A solution would be to just parse it out:

value = new Date(parseInt(value.replace("/Date(", "").replace(")/",""), 10));

However I've heard that there is a setting somewhere to get the serializer to output DateTime objects with the new Date(xxx) syntax. I'll try to dig that out.

The second parameter of JSON.parse() accepts a reviver function where prescribes how the value originally produced by, before being returned.

Here is an example for date:

var parsed = JSON.parse(data, function(key, value) {
  if (typeof value === 'string') {
    var d = /\/Date\((\d*)\)\//.exec(value);
    return (d) ? new Date(+d[1]) : value;
  }
  return value;
});

See the docs of JSON.parse()

re.match is anchored at the beginning of the string. That has nothing to do with newlines, so it is not the same as using ^ in the pattern.

As the re.match documentation says:

If zero or more characters at the beginning of string match the regular expression pattern, return a corresponding MatchObject instance. Return None if the string does not match the pattern; note that this is different from a zero-length match.

Note: If you want to locate a match anywhere in string, use search() instead.

re.search searches the entire string, as the documentation says:

Scan through string looking for a location where the regular expression pattern produces a match, and return a corresponding MatchObject instance. Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string.

So if you need to match at the beginning of the string, or to match the entire string use match. It is faster. Otherwise use search.

The documentation has a specific section for match vs. search that also covers multiline strings:

Python offers two different primitive operations based on regular expressions: match checks for a match only at the beginning of the string, while search checks for a match anywhere in the string (this is what Perl does by default).

Note that match may differ from search even when using a regular expression beginning with '^': '^' matches only at the start of the string, or in MULTILINE mode also immediately following a newline. The “match” operation succeeds only if the pattern matches at the start of the string regardless of mode, or at the starting position given by the optional pos argument regardless of whether a newline precedes it.

Now, enough talk. Time to see some example code:

# example code:
string_with_newlines = """something
someotherthing"""

import re

print re.match('some', string_with_newlines) # matches
print re.match('someother', 
               string_with_newlines) # won't match
print re.match('^someother', string_with_newlines, 
               re.MULTILINE) # also won't match
print re.search('someother', 
                string_with_newlines) # finds something
print re.search('^someother', string_with_newlines, 
                re.MULTILINE) # also finds something

m = re.compile('thing$', re.MULTILINE)

print m.match(string_with_newlines) # no match
print m.match(string_with_newlines, pos=4) # matches
print m.search(string_with_newlines, 
               re.MULTILINE) # also matches

It is 2017, but this thread is top in my search engine, today the following methods are preferred (initializer lists)

std::vector<std::string> v = { "xyzzy", "plugh", "abracadabra" };
std::vector<std::string> v({ "xyzzy", "plugh", "abracadabra" });
std::vector<std::string> v{ "xyzzy", "plugh", "abracadabra" };

I Faced the same issue while installing a setup using a jar file. Solution thta worked for me is

1. open command prompt as administrator
2. Go to jdk bin directory (Ex.C:\Program Files\Java\jdk1.8.0_73\bin)
3. now execute java -jar <<jar fully qualified path>>

It worked for me :)

Since most of the answers to this question are between 2009 and 2014 (except for a comment in 2018), there should be an update to this.

I found a solution to the wrap-text problem brought up by Spongman on Jun 11 '14 at 23:20. He has an example here: jsfiddle.net/vPpD4

If you add the following in the CSS under the div tag in the jsfiddle.net/vPpD4 example, you get the desired wrap-text effect that I think Spongman was asking about. I don't know how far back this is applicable, but this works in all of the current (as of Dec 2020/Jan 2021) browsers available for Windows computers. Note: I have not tested this on the Apple Safari browser. I have also not tested this on any mobile devices.

    div img { 
        float: left;
    }
    .clearfix::after {
        content: ""; 
        clear: both;
        display: table;
    }

I also added a border around the image, just so that the reader will understand where the edge of the image is and why the text wraps as it does. The resulting example looks is here: http://jsfiddle.net/tqg7hLzk/

I have to offer this as a better approach - you don't always have the luxury of an identity field:

UPDATE m
SET [status]=10
FROM (
  Select TOP (10) *
  FROM messages
  WHERE [status]=0
  ORDER BY [priority] DESC
) m

You can also make the sub-query as complicated as you want - joining multiple tables, etc...

Why is this better? It does not rely on the presence of an identity field (or any other unique column) in the messages table. It can be used to update the top N rows from any table, even if that table has no unique key at all.

For demo code that conforms to POSIX standard as described in Setting Terminal Modes Properly and Serial Programming Guide for POSIX Operating Systems, the following is offered.
This code should execute correctly using Linux on x86 as well as ARM (or even CRIS) processors.
It's essentially derived from the other answer, but inaccurate and misleading comments have been corrected.

This demo program opens and initializes a serial terminal at 115200 baud for non-canonical mode that is as portable as possible.
The program transmits a hardcoded text string to the other terminal, and delays while the output is performed.
The program then enters an infinite loop to receive and display data from the serial terminal.
By default the received data is displayed as hexadecimal byte values.

To make the program treat the received data as ASCII codes, compile the program with the symbol DISPLAY_STRING, e.g.

 cc -DDISPLAY_STRING demo.c

If the received data is ASCII text (rather than binary data) and you want to read it as lines terminated by the newline character, then see this answer for a sample program.

I know this question is already been answered but for new comers those two solutions may help:

1. Make sure your gmail is allowing low secure apps to sign in, you can turn it on here: https://www.google.com/settings/security/lesssecureapps.
2. Change your password.

I'm with a similar problem, but, in filenames of a file I'm compressing with apache commons. So, i resolved it with this command:

convmv --notest -f cp1252 -t utf8 * -r

it works very well for me. Hope it help anyone ;)

For current datetime, you can use now() function in postgresql insert query.

You can also refer following link.

insert statement in postgres for data type timestamp without time zone NOT NULL,.

If you want to pass a parameter to the delayed function:

    setTimeout(setTimer, 3000, param1, param2);

I'm currently managing a MySQL database on Amazon's cloud infrastructure that has grown to 160 GB. Query performance is fine. What has become a nightmare is backups, restores, adding slaves, or anything else that deals with the whole dataset, or even DDL on large tables. Getting a clean import of a dump file has become problematic. In order to make the process stable enough to automate, various choices needed to be made to prioritize stability over performance. If we ever had to recover from a disaster using a SQL backup, we'd be down for days.

Horizontally scaling SQL is also pretty painful, and in most cases leads to using it in ways you probably did not intend when you chose to put your data in SQL in the first place. Shards, read slaves, multi-master, et al, they are all really shitty solutions that add complexity to everything you ever do with the DB, and not one of them solves the problem; only mitigates it in some ways. I would strongly suggest looking at moving some of your data out of MySQL (or really any SQL) when you start approaching a dataset of a size where these types of things become an issue.

Update: a few years later, and our dataset has grown to about 800 GiB. In addition, we have a single table which is 200+ GiB and a few others in the 50-100 GiB range. Everything I said before holds. It still performs just fine, but the problems of running full dataset operations have become worse.

TextMate with the Django and django-html bundles installed gives you syntax highlighting and great extensibility. It is lightweight and fun to use.

Here is a link to a code completion project for TextMate with Python (which I haven't used myself). As for "intellisense" (which I understand to be inline-doc reference), TextMate has that too.

I don't know if maybe it's a difference in Excel version but this question is 6 years old and the accepted answer didn't help me so this is what I figured out:

Under Conditional Formatting > Manage Rules:

1. Make a new rule with "Use a formula to determine which cells to format"
2. Make your rule, but put a dollar sign only in front of the letter: $A2<$B2
3. Under "Applies to", Manually select the second column (It would not work for me if I changed the value in the box, it just kept snapping back to what was already there), so it looks like $B$2:$B$100 (assuming you have 100 rows)

This worked for me in Excel 2016.

Try this:

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

or equivalent:

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

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

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

var objectA = {}

is a lot quicker and, in my experience, more commonly used, so it's probably best to adopt the 'standard' and save some typing.

As GateKiller said you need to change the maxRequestLength. You may also need to change the executionTimeout in case the upload speed is too slow. Note that you don't want either of these settings to be too big otherwise you'll be open to DOS attacks.

The default for the executionTimeout is 360 seconds or 6 minutes.

You can change the maxRequestLength and executionTimeout with the httpRuntime Element.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <httpRuntime maxRequestLength="102400" executionTimeout="1200" />
    </system.web>
</configuration>

EDIT:

If you want to handle the exception regardless then as has been stated already you'll need to handle it in Global.asax. Here's a link to a code example.

The accepted answer is problematic for http urls. Moreover Uri.LocalPath does Windows specific conversions, and as someone pointed out leaves query strings in there. A better way is to use Uri.AbsolutePath

The correct way to do this for http urls is:

Uri uri = new Uri(hreflink);
string filename = System.IO.Path.GetFileName(uri.AbsolutePath);

I looked at using KeychainItemWrapper (the ARC version) but I didn't find its Objective C wrapper as wholesome as desired.

I used this solution by Kishikawa Katsumi, which meant I wrote less code and didn't have to use casts to store NSString values.

Two examples of storing:

[UICKeyChainStore setString:@"kishikawakatsumi" forKey:@"username"];
[UICKeyChainStore setString:@"P455_w0rd$1$G$Z$" forKey:@"password"];

Two examples of retrieving

UICKeyChainStore *store = [UICKeyChainStore keyChainStore];
    // or
UICKeyChainStore *store = [UICKeyChainStore keyChainStoreWithService:@"YOUR_SERVICE"];

NSString *username = [store stringForKey:@"username"];
NSString *password = [store stringForKey:@"password"];

For Some reason it is not working so we can do this by another way

just remove the line and add this :-

<a onclick="window.open ('http://www.foracure.org.au', ''); return false" href="javascript:void(0);"></a>

Good luck.

This was how I solved it:

I compiled some of the other answers into a single utility method:

public class TimeLimitedCodeBlock {

  public static void runWithTimeout(final Runnable runnable, long timeout, TimeUnit timeUnit) throws Exception {
    runWithTimeout(new Callable<Object>() {
      @Override
      public Object call() throws Exception {
        runnable.run();
        return null;
      }
    }, timeout, timeUnit);
  }

  public static <T> T runWithTimeout(Callable<T> callable, long timeout, TimeUnit timeUnit) throws Exception {
    final ExecutorService executor = Executors.newSingleThreadExecutor();
    final Future<T> future = executor.submit(callable);
    executor.shutdown(); // This does not cancel the already-scheduled task.
    try {
      return future.get(timeout, timeUnit);
    }
    catch (TimeoutException e) {
      //remove this if you do not want to cancel the job in progress
      //or set the argument to 'false' if you do not want to interrupt the thread
      future.cancel(true);
      throw e;
    }
    catch (ExecutionException e) {
      //unwrap the root cause
      Throwable t = e.getCause();
      if (t instanceof Error) {
        throw (Error) t;
      } else if (t instanceof Exception) {
        throw (Exception) t;
      } else {
        throw new IllegalStateException(t);
      }
    }
  }

}

Sample code making use of this utility method:

  public static void main(String[] args) throws Exception {
    final long startTime = System.currentTimeMillis();
    log(startTime, "calling runWithTimeout!");
    try {
      TimeLimitedCodeBlock.runWithTimeout(new Runnable() {
        @Override
        public void run() {
          try {
            log(startTime, "starting sleep!");
            Thread.sleep(10000);
            log(startTime, "woke up!");
          }
          catch (InterruptedException e) {
            log(startTime, "was interrupted!");
          }
        }
      }, 5, TimeUnit.SECONDS);
    }
    catch (TimeoutException e) {
      log(startTime, "got timeout!");
    }
    log(startTime, "end of main method!");
  }

  private static void log(long startTime, String msg) {
    long elapsedSeconds = (System.currentTimeMillis() - startTime);
    System.out.format("%1$5sms [%2$16s] %3$s\n", elapsedSeconds, Thread.currentThread().getName(), msg);
  }

Output from running the sample code on my machine:

    0ms [            main] calling runWithTimeout!
   13ms [ pool-1-thread-1] starting sleep!
 5015ms [            main] got timeout!
 5016ms [            main] end of main method!
 5015ms [ pool-1-thread-1] was interrupted!

You generally shouldn't use e.g. const int in a header file, if it's included in several source files. That is because then the variables will be defined once per source file (translation units technically speaking) because global const variables are implicitly static, taking up more memory than required.

You should instead have a special source file, Constants.cpp that actually defines the variables, and then have the variables declared as extern in the header file.

Something like this header file:

// Protect against multiple inclusions in the same source file
#ifndef CONSTANTS_H
#define CONSTANTS_H

extern const int CONSTANT_1;

#endif

And this in a source file:

const int CONSTANT_1 = 123;

In my case I needed to get the data type for Dynamic SQL (Shudder!) anyway here is a function that I created that returns the full data type. For example instead of returning 'decimal' it would return DECIMAL(18,4): dbo.GetLiteralDataType

var Text = File.ReadAllLines("Path"); foreach (var i in Text) {    var SplitText = i.Split().Where(x=> x.Lenght>1).ToList();    //@Array1 add SplitText[0]    //@Array2 add SpliteText[1]   }  

If more than one result is expected, then the getResponse() method will return a Vector containing the various responses.

In which case the offending code becomes:

Object result = envelope.getResponse();

// treat result as a vector
String resultText = null;
if (result instanceof Vector)
{
    SoapPrimitive element0 = (SoapPrimitive)((Vector) result).elementAt(0);
    resultText = element0.toString();
}

tv.setText(resultText);

Answer based on the ksoap2-android (mosabua fork)

Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.

Iterator<String> itr2 = keys.iterator();
    while(itr2.hasNext()){
        String v = itr2.next();
        System.out.println("Key: "+v+" ,value: "+m.get(v));
    }

EDIT: Consider looking at and upvoting Malvineous's answer on this page. Netmasks are a much more elegant solution.

Simply use a percent sign as a wildcard in the IP address.

From http://dev.mysql.com/doc/refman/5.1/en/grant.html

You can specify wildcards in the host name. For example, user_name@'%.example.com' applies to user_name for any host in the example.com domain, and user_name@'192.168.1.%' applies to user_name for any host in the 192.168.1 class C subnet.

My inclination is to agree that stripping non-digits and just accepting what's there is best. Maybe to ensure at least a couple digits are present, although that does prohibit something like an alphabetic phone number "ASK-JAKE" for example.

A couple simple perl expressions might be:

@f = /(\d+)/g;
tr/0-9//dc;

Use the first one to keep the digit groups together, which may give formatting clues. Use the second one to trivially toss all non-digits.

Is it a worry that there may need to be a pause and then more keys entered? Or something like 555-1212 (wait for the beep) 123?

To sort dictionary, we could make use of operator module. Here is the operator module documentation.

import operator                             #Importing operator module
dc =  {"aa": 3, "bb": 4, "cc": 2, "dd": 1}  #Dictionary to be sorted

dc_sort = sorted(dc.items(),key = operator.itemgetter(1),reverse = True)
print dc_sort

Output sequence will be a sorted list :

[('bb', 4), ('aa', 3), ('cc', 2), ('dd', 1)]

If we want to sort with respect to keys, we can make use of

dc_sort = sorted(dc.items(),key = operator.itemgetter(0),reverse = True)

Output sequence will be :

[('dd', 1), ('cc', 2), ('bb', 4), ('aa', 3)]

import sys

try: 
    # your code here
except Exception as err:
    print("Error: " + str(err))
sys.exit(50) # whatever non zero exit code

I extended David West's great answer so that you can input a string and tell it all the substrings you would like to embolden:

func addBoldText(fullString: NSString, boldPartsOfString: Array<NSString>, font: UIFont!, boldFont: UIFont!) -> NSAttributedString {
    let nonBoldFontAttribute = [NSFontAttributeName:font!]
    let boldFontAttribute = [NSFontAttributeName:boldFont!]
    let boldString = NSMutableAttributedString(string: fullString as String, attributes:nonBoldFontAttribute)
    for i in 0 ..< boldPartsOfString.count {
        boldString.addAttributes(boldFontAttribute, range: fullString.rangeOfString(boldPartsOfString[i] as String))
    }
    return boldString
}

And then call it like this:

let normalFont = UIFont(name: "Dosis-Medium", size: 18)
let boldSearchFont = UIFont(name: "Dosis-Bold", size: 18)
self.UILabel.attributedText = addBoldText("Check again in 30 days to find more friends", boldPartsOfString: ["Check", "30 days", "find", "friends"], font: normalFont!, boldFont: boldSearchFont!)

This will embolden all the substrings you want bolded in your given string

@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs sizes so you won't notice, but if you used anything else (e.g. col-sm, col-md, etc), you'd understand.

Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/

.left-side {
  background-color: blue;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.something {
  height: 100%;
  background-color: red;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.row {
  background-color: green;
  overflow: hidden;
}

ReducedForm is a type, so you cannot say

ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

You can only use the . operator on an instance:

ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

You're looking for the toggle_comment command. (Edit > Comment > Toggle Comment)

By default, this command is mapped to:

• Ctrl+/ (On Windows and Linux)
• Command ?+/ (On Mac)

This command also takes a block argument, which allows you to use block comments instead of single lines (e.g. /* ... */ as opposed to // ... in JavaScript). By default, the following key combinations are mapped to toggle block comments:

• Ctrl+Shift+/ (On Windows and Linux)
• Command ?+Alt+/ (On Mac)

This is not another code as you have already helped yourself; but for you to take a look at the performance when using Excel functions in VBA.

• Match() is faster for smaller number of search, but it isn't when it compared to a large number of data. And in that instance you may consider a variant array/dictionary/arrayList approach depending on if you want to sort, you want to have duplicates or not..

• Error handling on Match

PS: **On a latter note, if you wish to do pattern matching then you may consider ScriptingObject **Regex.

You can certainly #define a macro as shown below. The compiler will replace "IMAGE_SEGMENT" with its value before compilation. While you will achieve defining a global lookup for your array, it is not the same as a global variable. When the macro is expanded, it works just like inline code and so a new image is created each time. So if you are careful in where you use the macro, then you would have effectively achieved creating a global variable.

#define IMAGE_SEGMENT [[NSImage alloc] initWithContentsOfFile:@"/User/asd.jpg"];

Then use it where you need it as shown below. Each time the below code is executed, a new object is created with a new memory pointer.

imageSegment = IMAGE_SEGMENT

Here is a function that will load CSS files with a success or failure callback. The failure callback will be called just once, if one or more resources fail to load. I think this approach is better than some of the other solutions because inserting a element into the DOM with an HREF causes an additional browser request (albeit, the request will likely come from cache, depending on response headers).

function loadCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            return $.get(url, function(css) {
                $("<style>" + css + "</style>").appendTo("head");
            });
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

Usage as so:

loadCssFiles(["https://test.com/style1.css", "https://test.com/style2.css",],
    function() {
    alert("All resources loaded");
}, function() {
    alert("One or more resources failed to load");
});

Here is another function that will load both CSS and javascript files:

function loadJavascriptAndCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            if(url.endsWith(".css")) {
                return $.get(url, function(css) {
                    $("<style>" + css + "</style>").appendTo("head");
                });
            } else {
                return $.getScript(url);
            }
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

As far as I know the correct way to check it is:

if [ $(id -u) = "0" ]; then
    echo "You are root"
else
    echo "You are NOT root"
fi

See "Testing For Root" section here:

http://linuxcommand.org/lc3_wss0080.php

As a general rule, pop up blockers target windows that launch without user interaction. Usually a click event can open a window without it being blocked. (unless it's a really bad popup blocker)

Try launching after a click event

To filter an array irrespective of the property type (i.e. for all property types), we can create a custom filter pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({ name: "filter" })
export class ManualFilterPipe implements PipeTransform {
  transform(itemList: any, searchKeyword: string) {
    if (!itemList)
      return [];
    if (!searchKeyword)
      return itemList;
    let filteredList = [];
    if (itemList.length > 0) {
      searchKeyword = searchKeyword.toLowerCase();
      itemList.forEach(item => {
        //Object.values(item) => gives the list of all the property values of the 'item' object
        let propValueList = Object.values(item);
        for(let i=0;i<propValueList.length;i++)
        {
          if (propValueList[i]) {
            if (propValueList[i].toString().toLowerCase().indexOf(searchKeyword) > -1)
            {
              filteredList.push(item);
              break;
            }
          }
        }
      });
    }
    return filteredList;
  }
}

//Usage

//<tr *ngFor="let company of companyList | filter: searchKeyword"></tr>

Don't forget to import the pipe in the app module

We might need to customize the logic to filer with dates.

document.documentMode is undefined if the browser is not IE8,

it returns 8 for standards mode and 7 for 'compatable to IE7'

If it is running as IE7 there are a lot of css and dom features that won't be supported.

Using Dapper. so i added this i hope anyone help.

public void Insert(ProductName obj)
        {
            SqlConnection connection = new SqlConnection(Connection.GetConnectionString());
            connection.Open();
            connection.Execute("ProductName_sp", new
            { @Name = obj.Name, @Code = obj.Code, @CategoryId = obj.CategoryId, @CompanyId = obj.CompanyId, @ReorderLebel = obj.ReorderLebel, @logo = obj.logo,@Status=obj.Status, @ProductPrice = obj.ProductPrice,
                @SellingPrice = obj.SellingPrice, @VatPercent = obj.VatPercent, @Description=obj.Description, @ColourId = obj.ColourId, @SizeId = obj.SizeId,
                @BrandId = obj.BrandId, @DisCountPercent = obj.DisCountPercent, @CreateById =obj.CreateById, @StatementType = "Create" }, commandType: CommandType.StoredProcedure);

        }

The easiest way I find is to create a file "any_name.pth" and put it in your folder "\Lib\site-packages". You should find that folder wherever python is installed.

In that file, put a list of directories where you want to keep modules for importing. For instance, make a line in that file like this:

C:\Users\example...\example

You will be able to tell it works by running this in python:

import sys
for line in sys: print line

You will see your directory printed out, amongst others from where you can also import. Now you can import a "mymodule.py" file that sits in that directory as easily as:

import mymodule

This will not import subfolders. For that you could imagine creating a python script to create a .pth file containing all sub folders of a folder you define. Have it run at startup perhaps.

Here's another one I just wrote that supports arrays. It concats them.

function isObject(obj) {
    return obj !== null && typeof obj === 'object';
}


function isPlainObject(obj) {
    return isObject(obj) && (
        obj.constructor === Object  // obj = {}
        || obj.constructor === undefined // obj = Object.create(null)
    );
}

function mergeDeep(target, ...sources) {
    if (!sources.length) return target;
    const source = sources.shift();

    if(Array.isArray(target)) {
        if(Array.isArray(source)) {
            target.push(...source);
        } else {
            target.push(source);
        }
    } else if(isPlainObject(target)) {
        if(isPlainObject(source)) {
            for(let key of Object.keys(source)) {
                if(!target[key]) {
                    target[key] = source[key];
                } else {
                    mergeDeep(target[key], source[key]);
                }
            }
        } else {
            throw new Error(`Cannot merge object with non-object`);
        }
    } else {
        target = source;
    }

    return mergeDeep(target, ...sources);
};

java.time

UPDATE

The other Questions are outmoded. The terrible legacy classes such as SimpleDateFormat were supplanted years ago by the modern java.time classes.

Custom

For defining your own custom formatting patterns, the codes in DateTimeFormatter are similar to but not exactly the same as the codes in SimpleDateFormat. Be sure to study the documentation. And search Stack Overflow for many examples.

DateTimeFormatter f = 
    DateTimeFormatter.ofPattern( 
        "dd MMM uuuu" , 
        Locale.ITALY 
    ) 
;

Standard ISO 8601

The ISO 8601 standard defines formats for many types of date-time values. These formats are designed for data-exchange, being easily parsed by machine as well as easily read by humans across cultures.

The java.time classes use ISO 8601 formats by default when generating/parsing strings. Simply call the toString & parse methods. No need to specify a formatting pattern.

Instant.now().toString()

2018-11-05T18:19:33.017554Z

For a value in UTC, the Z on the end means UTC, and is pronounced “Zulu”.

Localize

Rather than specify a formatting pattern, you can let java.time automatically localize for you. Use the DateTimeFormatter.ofLocalized… methods.

Get current moment with the wall-clock time used by the people of a particular region (a time zone).

ZoneId z = ZoneId.of( "Africa/Tunis" );
ZonedDateTime zdt = ZonedDateTime.now( z );

Generate text in standard ISO 8601 format wisely extended to append the name of the time zone in square brackets.

zdt.toString(): 2018-11-05T19:20:23.765293+01:00[Africa/Tunis]

Generate auto-localized text.

Locale locale = Locale.CANADA_FRENCH;
DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL ).withLocale( locale );

String output = zdt.format( f );

output: lundi 5 novembre 2018 à 19:20:23 heure normale d’Europe centrale

Generally a better practice to auto-localize rather than fret with hard-coded formatting patterns.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

simply assign a variable to () or " ", then when needed type

print(x, x, x, Hello World, x)

or something like that.

Hope this is a little less complicated:)

I've tried lots of different answers in different forums. I guess it depends on the machine your developing. But I haved used the statement

ax.lines = []

and works perfectly. I don't use cla() cause it deletes all the definitions I've made to the plot

Ex.

pylab.setp(_self.ax.get_yticklabels(), fontsize=8)

but I've tried deleting the lines many times. Also using the weakref library to check the reference to that line while I was deleting but nothing worked for me.

Hope this works for someone else =D

I recently ran into this kinda issue, where I need to communicate between client and server using websocket in a PHP based codeigniter project.

I resolved this issue by adding my port(node app running on) into Allow incoming TCP ports & Allow outgoing TCP ports lists.

You can find these configurations in Firewall Configurations in your server's WHM panel.

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

If one assumes he really needs regexp - which is perfectly reasonable in many contexts - the problem is that the specific regexp variety needs to be specified. For example:

egrep '^(100|[1-9]|[1-9][0-9])$'
grep -E '^(100|[1-9]|[1-9][0-9])$'

work fine if the (...|...) alternative syntax is available. In other contexts, they'd be backslashed like \(...\|...\)

middleware as the name suggests actually middleware is sit between middle.. middle of what? middle of request and response..how request,response,express server sit in express app in this picture you can see requests are coming from client then the express server server serves those requests.. then lets dig deeper.. actually we can divide this whole express server's whole task in to small seperate tasks like in this way. how middleware sit between request and response small chunk of server parts doing some particular task and passed request to next one.. finally doing all the tasks response has been made.. all middle ware can access request object,response object and next function of request response cycle..

this is good example for explaining middleware in express youtube video for middleware

keyPressed - when the key goes down
keyReleased - when the key comes up
keyTyped - when the unicode character represented by this key is sent by the keyboard to system input.

I personally would use keyReleased for this. It will fire only when they lift their finger up.

Note that keyTyped will only work for something that can be printed (I don't know if F5 can or not) and I believe will fire over and over again if the key is held down. This would be useful for something like... moving a character across the screen or something.

Notes:

• Each "mimic" has a "mimicState" object for its logical state. This provides a clear distinction between the Servlet API methods and the configuration and inspection of the mimic's internal state.

• You might be surprised that the check of Content-Type includes "charset=ISO-8859-1". However, for the given "doPost" code this is as per the Servlet API Javadoc, and the HttpServletResponse's own getContentType method, and the actual Content-Type header produced on e.g. Glassfish 3. You might not realise this if using normal mock objects and your own expectations of the API's behaviour. In this case it probably doesn't matter, but in more complex cases this is the sort of unanticipated API behaviour that can make a bit of a mockery of mocks!

• I've used response.getMimicState().getContentType() as the simplest way to check Content-Type and illustrate the above point, but you could indeed check for "text/html" on its own if you wanted (using response.getMimicState().getContentTypeMimeType()). Checking the Content-Type header the same way as for the Cache-Control header also works.

• For this example the response content is checked as character data (with this using the Writer's encoding). We could also check that the response's Writer was used rather than its OutputStream (using response.getMimicState().isWritingCharacterContent()), but I've taken it that we're only concerned with the resulting output, and don't care what API calls produced it (though that could be checked too...). It's also possible to retrieve the response's body content as bytes, examine the detailed state of the Writer/OutputStream etc.

Error 13 is nothing but the permission issues. Even i had the same issue and was unable to load data to mysql table and then resolved the issue myself.

Here's the solution:

Bydefault the

--local-infile is set to value 0

, inorder to use LOAD DATA LOCAL INFILE it must be enabled.

So Start mySQL like this :

mysql -u username -p --local-infile

This will make LOCAL INFILE enabled during startup and thus there wont be any issues using it !

You don't need an onclick. Assuming you're using Bootstrap 3 Bootstrap 3 Documentation

<div class="span4 proj-div" data-toggle="modal" data-target="#GSCCModal">Clickable content, graphics, whatever</div>

<div id="GSCCModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
 <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;  </button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>

Another way to check on connection attempts is to look at the server's event log. On my Windows 2008 R2 Enterprise machine I opened the server manager (right-click on Computer and select Manage. Then choose Diagnostics -> Event Viewer -> Windows Logs -> Applcation. You can filter the log to isolate the MSSQLSERVER events. I found a number that looked like this
