Programs & Examples On #Tools.jar

There are two directories that looks like JDK.

  C:\Program Files\Java\jdk1.7.0_02
  C:\Program Files (x86)\Java\jdk1.7.0_02\

This may be due to both 64 bit and 32 bit JDK installed? What ever may be the case, the java.exe seen by ant.bat should from the JDK. If the JRE's java.exe comes first in the path, that will be used to guess the JDK location.

Put 'C:\Program Files (x86)\Java\jdk1.7.0_02\bin' or 'C:\Program Files\Java\jdk1.7.0_02' as the first argument in the path.

Further steps:

You can take output of ant -diagnostics and look for interesting keys. (assuming Sun/Oracle JDK).

 java.class.path 
 java.library.path
 sun.boot.library.path

(in my case tools.jar appears in java.class.path)

Using suggestions from answers on this page and this other one (ANT_HOME is set incorrectly or ant could not be located), the ultimate fix was the following:

1. Adding a ANT_HOME environment variable that points to the ROOT directory of your Apache ant directory location. (Not the bin sub-dir!)

2. Adding a JAVA_HOME environment variable that points to the ROOT directory of your Java JDK (or SDK) directory location. (NOT your JRE and not the bin sub-dir!)

3. Appended %ANT_HOME%\bin;%JAVA_HOME%\bin to the PATH environment variable.

4. Make sure you close any command window(s) that were open prior to the changes above. Only command windows opened after the changes will have the updated environment variables.

An easy way is :

        wstring your_wchar_in_ws(<your wchar>);
        string your_wchar_in_str(your_wchar_in_ws.begin(), your_wchar_in_ws.end());
        char* your_wchar_in_char =  your_wchar_in_str.c_str();

I'm using this method for years :)

When you declare

public static <T> void foo(List<T>... bar) the compiler converts it to

public static <T> void foo(List<T>[] bar) then to

public static void foo(List[] bar)

The danger then arises that you'll mistakenly assign incorrect values into the list and the compiler will not trigger any error. For example, if T is a String then the following code will compile without error but will fail at runtime:

// First, strip away the array type (arrays allow this kind of upcasting)
Object[] objectArray = bar;

// Next, insert an element with an incorrect type into the array
objectArray[0] = Arrays.asList(new Integer(42));

// Finally, try accessing the original array. A runtime error will occur
// (ClassCastException due to a casting from Integer to String)
T firstElement = bar[0].get(0);

If you reviewed the method to ensure that it doesn't contain such vulnerabilities then you can annotate it with @SafeVarargs to suppress the warning. For interfaces, use @SuppressWarnings("unchecked").

If you get this error message:

Varargs method could cause heap pollution from non-reifiable varargs parameter

and you are sure that your usage is safe then you should use @SuppressWarnings("varargs") instead. See Is @SafeVarargs an appropriate annotation for this method? and https://stackoverflow.com/a/14252221/14731 for a nice explanation of this second kind of error.

In order to achieve constructor chaining, the abstract class will have a constructor. The compiler keeps Super() statement inside the subclass constructor, which will call the superclass constructor. If there were no constructors for abstract classes then java rules are violated and we can't achieve constructor chaining.

<textarea rows="4" cols="50"></textarea>

It is equivalent to:

textarea {
    height: 4em;
    width: 50em;
}

where 1em is equivalent to the current font size, thus make the text area 50 chars wide. see here.

You can simply use one line javascript in browser console to convert a hex map key to base64. Open console in latest browser (F12 on Windows, ? Option+? Command+I on macOS, Ctrl+? Shift+I on Linux) and paste the code and replace the SHA-1, SHA-256 hex map that Google Play provides under Release Setup App signing:

Hex map key to Base64 key hash

> btoa('a7:77:d9:20:c8:01:dd:fa:2c:3b:db:b2:ef:c5:5a:1d:ae:f7:28:6f'.split(':').map(hc => String.fromCharCode(parseInt(hc, 16))).join(''))
< "p3fZIMgB3fosO9uy78VaHa73KG8="

You can also convert it here; run the below code snippet and paste hex map key and hit convert button:

document.getElementById('convert').addEventListener('click', function() {
  document.getElementById('result').textContent = btoa(
    document.getElementById('hex-map').value
      .split(':')
      .map(hc => String.fromCharCode(parseInt(hc, 16)))
      .join('')
  );
});

<textarea id="hex-map" placeholder="paste hex key map here" style="width: 100%"></textarea>
<button id="convert">Convert</button>
<p><code id="result"></code></p>

And if you want to reverse a key hash to check and validate it:

Reverse Base64 key hash to hex map key

> atob('p3fZIMgB3fosO9uy78VaHa73KG8=').split('').map(c => c.charCodeAt(0).toString(16)).join(':')
< "a7:77:d9:20:c8:1:dd:fa:2c:3b:db:b2:ef:c5:5a:1d:ae:f7:28:6f"

document.getElementById('convert').addEventListener('click', function() {
  document.getElementById('result').textContent = atob(document.getElementById('base64-hash').value)
    .split('')
    .map(c => c.charCodeAt(0).toString(16))
    .join(':')
});

<textarea id="base64-hash" placeholder="paste base64 key hash here" style="width: 100%"></textarea>
<button id="convert">Convert</button>
<p><code id="result"></code></p>

Ideally you would use str.find or str.index like demented hedgehog said. But you said you can't ...

Your problem is your code searches only for the first character of your search string which(the first one) is at index 2.

You are basically saying if char[0] is in s, increment index until ch == char[0] which returned 3 when I tested it but it was still wrong. Here's a way to do it.

def find_str(s, char):
    index = 0

    if char in s:
        c = char[0]
        for ch in s:
            if ch == c:
                if s[index:index+len(char)] == char:
                    return index

            index += 1

    return -1

print(find_str("Happy birthday", "py"))
print(find_str("Happy birthday", "rth"))
print(find_str("Happy birthday", "rh"))

It produced the following output:

3
8
-1

As suggested, you can use some 3rd party library, or do it manually (which is not that much work), but the simplest and the most flexible is to perhaps use the built-in functionality in .NET. For more see:

• System.Drawing.Image.PropertyItems Property

• System.Drawing.Imaging.PropertyItem Class

• How to: Read Image Metadata

I say "it’s the most flexible" because .NET does not try to interpret or coalesce the data in any way. For each EXIF you basically get an array of bytes. This may be good or bad depending on how much control you actually want.

Also, I should point out that the property list does not in fact directly correspond to the EXIF values. EXIF itself is stored in multiple tables with overlapping ID’s, but .NET puts everything in one list and redefines ID’s of some items. But as long as you don’t care about the precise EXIF ID’s, you should be fine with the .NET mapping.

Edit: It's possible to do it without loading the full image following this answer: https://stackoverflow.com/a/552642/2097240

Using callback plugins, you can have the stdout of your commands output in readable form with the play: gist: human_log.py

I improved from this:

SELECT 
    col, 
    COUNT(col)
FROM
    table_name
GROUP BY col
HAVING COUNT(col) > 1; 

if (strstr(request, "favicon") != NULL) {
    // contains
}

I had a similar situation with this issue. In this case it would have looked like this

Sub Test()
   MsqBox ("Hello world")
End Sub

The problem was, that I had a lot more code there and couldn't recognize, that there was a misspelling in "MsqBox" (q instead of g) and therefore I had an error, it was really misleading, but since you can get on this error like that, maybe someone else will notice that it was cause by a misspelling like this...

" the user is the one who select max no and min no ?" What do you mean by this line ?

You can use java function int random = Random.nextInt(n). This returns a random int in range[0, n-1]).

and you can set it in your textview using the setText() method

In laravel 5.3 $start = Input::get('start'); returns NULL

To solve this

use Illuminate\Support\Facades\Input;

//then inside you controller function  use

$input = Input::all(); // $input will have all your variables,  

$start = $input['start'];
$limit = $input['limit'];

In your theme's functions.php:

function my_custom_js() {
    echo '<script type="text/javascript" src="myscript.js"></script>';
}
// Add hook for admin <head></head>
add_action( 'admin_head', 'my_custom_js' );
// Add hook for front-end <head></head>
add_action( 'wp_head', 'my_custom_js' );

**403 Forbidden **

You don't have permission to access /Folder-Name/ on this server**

The solution for this problem is:

1.go to etc/apache2/apache2.conf

2.find the below code and change AllowOverride all to AllowOverride none

 <Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride all      Change this to--->  AllowOverride none
    Require all granted
 </Directory>

It will work fine on your Ubuntu server

I suppose you want to commit the changes to one branch and then make those changes visible in the other branch. In git you should have no changes on top of HEAD when changing branches.

You commit only the changed files by:

git commit [some files]

Or if you are sure that you have a clean staging area you can

git add [some files]       # add [some files] to staging area
git add [some more files]  # add [some more files] to staging area
git commit                 # commit [some files] and [some more files]

If you want to make that commit available on both branches you do

git stash                     # remove all changes from HEAD and save them somewhere else
git checkout <other-project>  # change branches
git cherry-pick <commit-id>   # pick a commit from ANY branch and apply it to the current
git checkout <first-project>  # change to the other branch
git stash pop                 # restore all changes again

you can create selector file in res/drawable

example: res/drawable/selector_button.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/btn_disabled" android:state_enabled="false" />
    <item android:drawable="@drawable/btn_enabled" />
</selector>

and in layout activity, fragment or etc

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/selector_bg_rectangle_black"/>

I had a similar problem due to a zombie vim.exe process. Killing it in Task Manager, followed by a git rebase --abort fixed it.

You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:

curl_setopt($ch, CURLOPT_PROXYTYPE, 7);

str_replace is considerably faster.

$find_letters = array('a', 'c', 'd');
$string = 'abcdefg';
$match = (str_replace($find_letters, '', $string) != $string);

For old Python (tested on 2.4) the top solution points the way. You can do this:

import string

def try_interp():
    d = 1
    f = 1.1
    s = "s"
    print string.Template("d: $d f: $f s: $s").substitute(**locals())

try_interp()

And you get

d: 1 f: 1.1 s: s

Simply put, If you want to pull from GitHub the branch the_branch_I_want:

git fetch origin
git branch -f the_branch_I_want origin/the_branch_I_want
git checkout the_branch_I_want

There's another way for the later versions, for example in 1.10:

{% load admin_urls %}
<a href="{% url opts|admin_urlname:'add' %}">Add user</a>
<a href="{% url opts|admin_urlname:'delete' user.pk %}">Delete this user</a>

Where opts is something like mymodelinstance._meta or MyModelClass._meta

One gotcha is you can't access underscore attributes directly in Django templates (like {{ myinstance._meta }}) so you have to pass the opts object in from the view as template context.

A Fiddle would have been more helpful nevertheless from what I understand, I guess what you need is persistent headers, look into this

http://css-tricks.com/persistent-headers/

By using

$_SERVER['REQUEST_METHOD']

Example

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
     // The request is using the POST method
}

For more details please see the documentation for the $_SERVER variable.

Are they just saying don't use session/application level data store???

No. They aren't saying that in a trivial way.

They're saying do not define a "session". Don't login. Don't logout. Provide credentials with the request. Each request stands alone.

You still have data stores. You still have authentication and authorization. You just don't waste time establishing sessions and maintaining session state.

The point is that each request (a) stands completely alone and (b) can be trivially farmed out to a giant parallel server farm without any actual work. Apache or Squid can pass RESTful requests around blindly and successfully.

What if I had a queue of messages, and my user wanted to read the messages, but as he read them, wanted to block certain senders messages coming through for the duration of his session?

If the user wants a filter, then simply provide the filter on each request.

Wouldn't it make sense to ... have the server only send messages (or message ID's) that were not blocked by the user?

Yes. Provide the filter in the RESTful URI request.

Do I really have to send the entire list of message senders to block each time I request the new message list?

Yes. How big can this "list of message senders to block" be? A short list of PK's?

A GET request can be very large. If necessary, you can try a POST request even though it sounds like a kind of query.

VI search and replace command examples

Let us say you would like to find a word called “foo” and replace with “bar”.

First hit [Esc] key

Type : (colon) followed by %s/foo/bar/ and hit [Enter] key

:%s/foo/bar/

Firstly, the code in the question does not produce the described output. It extracts the file extension ("txt") and not the file base name ("hello"). To do that the last line should call First(), not Last(), like this...

static string GetFileBaseNameUsingSplit(string path)
{
    string[] pathArr = path.Split('\\');
    string[] fileArr = pathArr.Last().Split('.');
    string fileBaseName = fileArr.First().ToString();

    return fileBaseName;
}

Having made that change, one thing to think about as far as improving this code is the amount of garbage it creates:

• A string[] containing one string for each path segment in path
• A string[] containing at least one string for each . in the last path segment in path

Therefore, extracting the base file name from the sample path "C:\Program Files\hello.txt" should produce the (temporary) objects "C:", "Program Files", "hello.txt", "hello", "txt", a string[3], and a string[2]. This could be significant if the method is called on a large number of paths. To improve this, we can search path ourselves to locate the start and end points of the base name and use those to create one new string...

static string GetFileBaseNameUsingSubstringUnsafe(string path)
{
    // Fails on paths with no file extension - DO NOT USE!!
    int startIndex = path.LastIndexOf('\\') + 1;
    int endIndex = path.IndexOf('.', startIndex);
    string fileBaseName = path.Substring(startIndex, endIndex - startIndex);

    return fileBaseName;
}

This is using the index of the character after the last \ as the start of the base name, and from there looking for the first . to use as the index of the character after the end of the base name. Is this shorter than the original code? Not quite. Is it a "smarter" solution? I think so. At least, it would be if not for the fact that...

As you can see from the comment, the previous method is problematic. Though it works if you assume all paths end with a file name with an extension, it will throw an exception if the path ends with \ (i.e. a directory path) or otherwise contains no extension in the last segment. To fix this, we need to add an extra check to account for when endIndex is -1 (i.e. . is not found)...

static string GetFileBaseNameUsingSubstring(string path)
{
    int startIndex = path.LastIndexOf('\\') + 1;
    int endIndex = path.IndexOf('.', startIndex);
    int length = (endIndex >= 0 ? endIndex : path.Length) - startIndex;
    string fileBaseName = path.Substring(startIndex, length);

    return fileBaseName;
}

Now this version is nowhere near shorter than the original, but it is more efficient and (now) correct, too.

As far as .NET methods that implement this functionality, many other answers suggest using Path.GetFileNameWithoutExtension(), which is an obvious, easy solution but does not produce the same results as the code in the question. There is a subtle but important difference between GetFileBaseNameUsingSplit() and Path.GetFileNameWithoutExtension() (GetFileBaseNameUsingPath() below): the former extracts everything before the first . and the latter extracts everything before the last .. This doesn't make a difference for the sample path in the question, but take a look at this table comparing the results of the above four methods when called with various paths...

...and you'll see that Path.GetFileNameWithoutExtension() yields different results when passed a path where the file name has a double extension or a leading and/or trailing .. You can try it for yourself with the following code...

TL;DR The code in the question does not behave as many seem to expect in some corner cases. If you're going to write your own path manipulation code, be sure to take into consideration...

• ...how you define a "filename without extension" (is it everything before the first . or everything before the last .?)
• ...files with multiple extensions
• ...files with no extension
• ...files with a leading .
• ...files with a trailing . (probably not something you'll ever encounter on Windows, but they are possible)
• ...directories with an "extension" or that otherwise contain a .
• ...paths that end with a \
• ...relative paths

Not all file paths follow the usual formula of X:\Directory\File.ext!

There are a few options:

Read all sheets directly into an ordered dictionary.

import pandas as pd

# for pandas version >= 0.21.0
sheet_to_df_map = pd.read_excel(file_name, sheet_name=None)

# for pandas version < 0.21.0
sheet_to_df_map = pd.read_excel(file_name, sheetname=None)

Read the first sheet directly into dataframe

df = pd.read_excel('excel_file_path.xls')
# this will read the first sheet into df

Read the excel file and get a list of sheets. Then chose and load the sheets.

xls = pd.ExcelFile('excel_file_path.xls')

# Now you can list all sheets in the file
xls.sheet_names
# ['house', 'house_extra', ...]

# to read just one sheet to dataframe:
df = pd.read_excel(file_name, sheetname="house")

Read all sheets and store it in a dictionary. Same as first but more explicit.

# to read all sheets to a map
sheet_to_df_map = {}
for sheet_name in xls.sheet_names:
    sheet_to_df_map[sheet_name] = xls.parse(sheet_name)
    # you can also use sheet_index [0,1,2..] instead of sheet name.

Thanks @ihightower for pointing it out way to read all sheets and @toto_tico for pointing out the version issue.

sheetname : string, int, mixed list of strings/ints, or None, default 0 Deprecated since version 0.21.0: Use sheet_name instead Source Link

$newDate = preg_replace("/(\d+)\D+(\d+)\D+(\d+)/","$3-$2-$1",$originalDate);

This code works for every date format.

You can change the order of replacement variables such $3-$1-$2 due to your old date format.

It's not a solution but a hint for those using Spring:

I tried to use org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean with setting persistenceXmlLocation but with this I had to provide the <class> elements (even if the persistenceXmlLocation just pointed to META-INF/persistence.xml).

When not using persistenceXmlLocation I could omit these <class> elements.

Microsoft has given us a cleaner, more convenient way of creating anonymous delegates called Lambda expressions. However, there is not a lot of attention being paid to the expressions portion of this statement. Microsoft released a entire namespace, System.Linq.Expressions, which contains classes to create expression trees based on lambda expressions. Expression trees are made up of objects that represent logic. For example, x = y + z is an expression that might be part of an expression tree in .Net. Consider the following (simple) example:

using System;
using System.Linq;
using System.Linq.Expressions;


namespace ExpressionTreeThingy
{
    class Program
    {
        static void Main(string[] args)
        {
            Expression<Func<int, int>> expr = (x) => x + 1; //this is not a delegate, but an object
            var del = expr.Compile(); //compiles the object to a CLR delegate, at runtime
            Console.WriteLine(del(5)); //we are just invoking a delegate at this point
            Console.ReadKey();
        }
    }
}

This example is trivial. And I am sure you are thinking, "This is useless as I could have directly created the delegate instead of creating an expression and compiling it at runtime". And you would be right. But this provides the foundation for expression trees. There are a number of expressions available in the Expressions namespaces, and you can build your own. I think you can see that this might be useful when you don't know exactly what the algorithm should be at design or compile time. I saw an example somewhere for using this to write a scientific calculator. You could also use it for Bayesian systems, or for genetic programming (AI). A few times in my career I have had to write Excel-like functionality that allowed users to enter simple expressions (addition, subtrations, etc) to operate on available data. In pre-.Net 3.5 I have had to resort to some scripting language external to C#, or had to use the code-emitting functionality in reflection to create .Net code on the fly. Now I would use expression trees.

Just for the sake of people who landed here for the same reason I did:

Don't use reserved keywords

I named a function in my class definition delete(), which is a reserved keyword and should not be used as a function name. Renaming it to deletion() (which also made sense semantically in my case) resolved the issue.

For a list of reserved keywords: http://en.cppreference.com/w/cpp/keyword

I quote: "Since they are used by the language, these keywords are not available for re-definition or overloading. "

These stages are suggestions. You can adapt the stages based on your business need. Some stages can be repeated for multiple types of testing, security, and performance. Depending on the complexity of your project and the structure of your teams, some stages can be repeated several times at different levels. For example, the end product of one team can become a dependency in the project of the next team. This means that the first team’s end product is subsequently staged as an artifact in the next team’s project.

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

Like this :

var id = $('div.foo').attr('id');
$('div.foo').attr('id', id + ' id_adding');

1. get actual ID
2. put actuel ID and add the new one

var newData = [1,2,3,4,5,6,7];
var chart = $('#chartjs').highcharts();
chart.series[0].setData(newData, true);

Explanation:
Variable newData contains value that want to update in chart. Variable chart is an object of a chart. setData is a method provided by highchart to update data.

Method setData contains two parameters, in first parameter we need to pass new value as array and second param is Boolean value. If true then chart updates itself and if false then we have to use redraw() method to update chart (i.e chart.redraw();)

Fully async version with ES6, only native packages, fs.promises and async/await, does file operations in parallel:

const fs = require('fs');
const path = require('path');

async function listDirectories(rootPath) {
    const fileNames = await fs.promises.readdir(rootPath);
    const filePaths = fileNames.map(fileName => path.join(rootPath, fileName));
    const filePathsAndIsDirectoryFlagsPromises = filePaths.map(async filePath => ({path: filePath, isDirectory: (await fs.promises.stat(filePath)).isDirectory()}))
    const filePathsAndIsDirectoryFlags = await Promise.all(filePathsAndIsDirectoryFlagsPromises);
    return filePathsAndIsDirectoryFlags.filter(filePathAndIsDirectoryFlag => filePathAndIsDirectoryFlag.isDirectory)
        .map(filePathAndIsDirectoryFlag => filePathAndIsDirectoryFlag.path);
}

Tested, it works nicely.

In answer to your general question of

So I am curious: What did I do to disorientate migrations? And what can I do to get it working with just one initial migration?

I've just had the same error message as you after I merged several branches and the migrations got confused about the current state of the database. Worst of all, this was only happening on the client's server, not on our development systems.

In trying to work out what was happening there, I came across this superb Microsoft guide:

Microsoft's guide to Code First Migrations in Team Environments

Whilst that guide was written to explain migrations in teams, it also gives the best explanation I've found of how the migrations work internally, which may well lead to an explanation for the behaviour your seeing. It's very worth putting an hour aside to read all of that for anyone who works with EF6 or below.

For anyone brought to this question by that error message after merging migrations, the trick of generating a blank migration with the current state of the database solved things for me, but do be very sure to have read the whole guide to know if that solution is appropriate in your case.

Using advanced wheres:

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) {
          $q->where('Cab', 2)
            ->orWhere('Cab', 4);
      })
      ->get();

Or, even better, using whereIn():

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->whereIn('Cab', $cabIds)
      ->get();

I wanted to get rid of OWIN in the project:

1. Delete OWIN references and Nuget packages from project
2. Clean & Rebuild project
3. Run app

Then I got OWIN error. These steps didn't work, because OWIN.dll was still in bin/ directory.

FIX:

1. Delete bin/ directory manually
2. Rebuild project

Simple and easy to understand, this will send the name of the button that has been clicked, then will branch off to do whatever you want. This can reduce the need for two targets. Less pages...!

table_ages <- subset(infert, select=c("age"))
summary(table_ages)
#            age       
#  Min.   :21.00  
#  1st Qu.:28.00  
#  Median :31.00  
#  Mean   :31.50  
#  3rd Qu.:35.25  
#  Max.   :44.00  

This is probably what they're looking for. summary(...) applied to a numeric returns the min, max, mean, median, and 25th and 75th percentile of the data.

Note that

summary(infert$age)
#    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
#   21.00   28.00   31.00   31.50   35.25   44.00 

The numbers are the same but the format is different. This is because table_ages is a data frame with one column (ages), whereas infert$age is a numeric vector. Try typing summary(infert).

This should work:

find DIR_NAME -type f | wc -l

Explanation:

• -type f to include only files.
• | (and not ¦) redirects find command's standard output to wc command's standard input.
• wc (short for word count) counts newlines, words and bytes on its input (docs).
• -l to count just newlines.

Notes:

• Replace DIR_NAME with . to execute the command in the current folder.
• You can also remove the -type f to include directories (and symlinks) in the count.
• It's possible this command will overcount if filenames can contain newline characters.

Explanation of why your example does not work:

In the command you showed, you do not use the "Pipe" (|) to kind-of connect two commands, but the broken bar (¦) which the shell does not recognize as a command or something similar. That's why you get that error message.

Use a list.

groups = [0]*3
for i in xrange(3):
    groups[i] = self.getGroup(selected, header + i)

or more "Pythonically":

groups = [self.getGroup(selected, header + i) for i in xrange(3)]

For what it's worth, you could try to create variables the "wrong" way, i.e. by modifying the dictionary which holds their values:

l = locals()
for i in xrange(3):
    l['group' + str(i)] = self.getGroup(selected, header + i)

but that's really bad form, and possibly not even guaranteed to work.

You could make use of APScheduler in your Flask application and run your jobs via its interface:

import atexit

# v2.x version - see https://stackoverflow.com/a/38501429/135978
# for the 3.x version
from apscheduler.scheduler import Scheduler
from flask import Flask

app = Flask(__name__)

cron = Scheduler(daemon=True)
# Explicitly kick off the background thread
cron.start()

@cron.interval_schedule(hours=1)
def job_function():
    # Do your work here


# Shutdown your cron thread if the web process is stopped
atexit.register(lambda: cron.shutdown(wait=False))

if __name__ == '__main__':
    app.run()

You are using a table variable i.e. you should declare the table. This is not a temporary table.

You create a temp table like so:

CREATE TABLE #customer
(
     Name varchar(32) not null
)

You declare a table variable like so:

DECLARE @Customer TABLE
(
      Name varchar(32) not null
)

Notice that a temp table is declared using # and a table variable is declared using a @. Go read about the difference between table variables and temp tables.

UPDATE:

Based on your comment below you are actually trying to create tables in a stored procedure. For this you would need to use dynamic SQL. Basically dynamic SQL allows you to construct a SQL Statement in the form of a string and then execute it. This is the ONLY way you will be able to create a table in a stored procedure. I am going to show you how and then discuss why this is not generally a good idea.

Now for a simple example (I have not tested this code but it should give you a good indication of how to do it):

CREATE PROCEDURE sproc_BuildTable 
    @TableName NVARCHAR(128)
   ,@Column1Name NVARCHAR(32)
   ,@Column1DataType NVARCHAR(32)
   ,@Column1Nullable NVARCHAR(32)
AS

   DECLARE @SQLString NVARCHAR(MAX)
   SET @SQString = 'CREATE TABLE '+@TableName + '( '+@Column1Name+' '+@Column1DataType +' '+@Column1Nullable +') ON PRIMARY '

   EXEC (@SQLString)
   GO

This stored procedure can be executed like this:

sproc_BuildTable 'Customers','CustomerName','VARCHAR(32)','NOT NULL'

There are some major problems with this type of stored procedure.

Its going to be difficult to cater for complex tables. Imagine the following table structure:

CREATE TABLE [dbo].[Customers] (
    [CustomerID] [int] IDENTITY(1,1) NOT NULL,
    [CustomerName] [nvarchar](64) NOT NULL,
    [CustomerSUrname] [nvarchar](64) NOT NULL,
    [CustomerDateOfBirth] [datetime] NOT NULL,
    [CustomerApprovedDiscount] [decimal](3, 2) NOT NULL,
    [CustomerActive] [bit] NOT NULL,
    CONSTRAINT [PK_Customers] PRIMARY KEY CLUSTERED 
    (
        [CustomerID] ASC
    ) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,      ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[Customers] ADD CONSTRAINT [DF_Customers_CustomerApprovedDiscount] DEFAULT ((0.00)) FOR [CustomerApprovedDiscount]
GO 

This table is a little more complex than the first example, but not a lot. The stored procedure will be much, much more complex to deal with. So while this approach might work for small tables it is quickly going to be unmanageable.

Creating tables require planning. When you create tables they should be placed strategically on different filegroups. This is to ensure that you don't cause disk I/O contention. How will you address scalability if everything is created on the primary file group?

Could you clarify why you need tables to be created dynamically?

UPDATE 2:

Delayed update due to workload. I read your comment about needing to create a table for each shop and I think you should look at doing it like the example I am about to give you.

In this example I make the following assumptions:

1. It's an e-commerce site that has many shops
2. A shop can have many items (goods) to sell.
3. A particular item (good) can be sold at many shops
4. A shop will charge different prices for different items (goods)
5. All prices are in $ (USD)

Let say this e-commerce site sells gaming consoles (i.e. Wii, PS3, XBOX360).

Looking at my assumptions I see a classical many-to-many relationship. A shop can sell many items (goods) and items (goods) can be sold at many shops. Let's break this down into tables.

First I would need a shop table to store all the information about the shop.

A simple shop table might look like this:

CREATE TABLE [dbo].[Shop](
    [ShopID] [int] IDENTITY(1,1) NOT NULL,
    [ShopName] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_Shop] PRIMARY KEY CLUSTERED 
    (
      [ShopID] ASC
    ) WITH (
              PAD_INDEX  = OFF
              , STATISTICS_NORECOMPUTE  = OFF
              , IGNORE_DUP_KEY = OFF
              , ALLOW_ROW_LOCKS  = ON
              , ALLOW_PAGE_LOCKS  = ON
    ) ON [PRIMARY]
    ) ON [PRIMARY]

    GO

Let's insert three shops into the database to use during our example. The following code will insert three shops:

INSERT INTO Shop
SELECT 'American Games R US'
UNION
SELECT 'Europe Gaming Experience'
UNION
SELECT 'Asian Games Emporium'

If you execute a SELECT * FROM Shop you will probably see the following:

ShopID  ShopName
1           American Games R US
2           Asian Games Emporium
3           Europe Gaming Experience

Right, so now let's move onto the Items (goods) table. Since the items/goods are products of various companies I am going to call the table product. You can execute the following code to create a simple Product table.

CREATE TABLE [dbo].[Product](
    [ProductID] [int] IDENTITY(1,1) NOT NULL,
    [ProductDescription] [nvarchar](128) NOT NULL,
 CONSTRAINT [PK_Product] PRIMARY KEY CLUSTERED 
 (
     [ProductID] ASC
 )WITH (PAD_INDEX  = OFF
        , STATISTICS_NORECOMPUTE  = OFF
        , IGNORE_DUP_KEY = OFF

Let's populate the products table with some products. Execute the following code to insert some products:

INSERT INTO Product
SELECT 'Wii'
UNION 
SELECT 'PS3'
UNION 
SELECT 'XBOX360'

If you execute SELECT * FROM Product you will probably see the following:

ProductID   ProductDescription
1           PS3
2           Wii
3           XBOX360

OK, at this point you have both product and shop information. So how do you bring them together? Well we know we can identify the shop by its ShopID primary key column and we know we can identify a product by its ProductID primary key column. Also, since each shop has a different price for each product we need to store the price the shop charges for the product.

So we have a table that maps the Shop to the product. We will call this table ShopProduct. A simple version of this table might look like this:

CREATE TABLE [dbo].[ShopProduct](
[ShopID] [int] NOT NULL,
[ProductID] [int] NOT NULL,
[Price] [money] NOT NULL,
CONSTRAINT [PK_ShopProduct] PRIMARY KEY CLUSTERED 
 (
     [ShopID] ASC,
      [ProductID] ASC
 )WITH (PAD_INDEX  = OFF,
     STATISTICS_NORECOMPUTE  = OFF, 
     IGNORE_DUP_KEY = OFF, 
     ALLOW_ROW_LOCKS  = ON,
     ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

 GO

So let's assume the American Games R Us shop only sells American consoles, the Europe Gaming Experience sells all consoles and the Asian Games Emporium sells only Asian consoles. We would need to map the primary keys from the shop and product tables into the ShopProduct table.

Here is how we are going to do the mapping. In my example the American Games R Us has a ShopID value of 1 (this is the primary key value) and I can see that the XBOX360 has a value of 3 and the shop has listed the XBOX360 for $159.99

By executing the following code you would complete the mapping:

INSERT INTO ShopProduct VALUES(1,3,159.99)

Now we want to add all product to the Europe Gaming Experience shop. In this example we know that the Europe Gaming Experience shop has a ShopID of 3 and since it sells all consoles we will need to insert the ProductID 1, 2 and 3 into the mapping table. Let's assume the prices for the consoles (products) at the Europe Gaming Experience shop are as follows: 1- The PS3 sells for $259.99 , 2- The Wii sells for $159.99 , 3- The XBOX360 sells for $199.99.

To get this mapping done you would need to execute the following code:

INSERT INTO ShopProduct VALUES(3,2,159.99) --This will insert the WII console into the mapping table for the Europe Gaming Experience Shop with a price of 159.99
INSERT INTO ShopProduct VALUES(3,1,259.99) --This will insert the PS3 console into the mapping table for the Europe Gaming Experience Shop with a price of 259.99
INSERT INTO ShopProduct VALUES(3,3,199.99) --This will insert the XBOX360 console into the mapping table for the Europe Gaming Experience Shop with a price of 199.99

At this point you have mapped two shops and their products into the mapping table. OK, so now how do I bring this all together to show a user browsing the website? Let's say you want to show all the product for the European Gaming Experience to a user on a web page – you would need to execute the following query:

SELECT      Shop.*
        , ShopProduct.*
        , Product.*
FROM         Shop 
INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
WHERE       Shop.ShopID=3

You will probably see the following results:

ShopID     ShopName                 ShopID  ProductID   Price   ProductID   ProductDescription
3          Europe Gaming Experience   3         1       259.99  1           PS3
3          Europe Gaming Experience   3         2       159.99  2           Wii
3          Europe Gaming Experience   3         3       199.99  3           XBOX360

Now for one last example, let's assume that your website has a feature which finds the cheapest price for a console. A user asks to find the cheapest prices for XBOX360.

You can execute the following query:

 SELECT     Shop.*
        , ShopProduct.*
        , Product.*
 FROM         Shop 
 INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
 INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
 WHERE      Product.ProductID =3  -- You can also use Product.ProductDescription = 'XBOX360'
 ORDER BY    Price ASC

This query will return a list of all shops which sells the XBOX360 with the cheapest shop first and so on.

You will notice that I have not added the Asian Games shop. As an exercise, add the Asian games shop to the mapping table with the following products: the Asian Games Emporium sells the Wii games console for $99.99 and the PS3 console for $159.99. If you work through this example you should now understand how to model a many-to-many relationship.

I hope this helps you in your travels with database design.

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

MERGE INTO OPT
USING
    (SELECT 1 "one" FROM dual) 
ON
    (OPT.email= '[email protected]' and OPT.campaign_id= 100) 
WHEN NOT matched THEN
INSERT (email, campaign_id)
VALUES ('[email protected]',100) 
;

You can also use an animator for it:

int secondsToRun = 999;

ValueAnimator timer = ValueAnimator.ofInt(secondsToRun);
timer.setDuration(secondsToRun * 1000).setInterpolator(new LinearInterpolator());
timer.addUpdateListener(new ValueAnimator.AnimatorUpdateListener()
    {
        @Override
        public void onAnimationUpdate(ValueAnimator animation)
        {
            int elapsedSeconds = (int) animation.getAnimatedValue();
            int minutes = elapsedSeconds / 60;
            int seconds = elapsedSeconds % 60;

            textView.setText(String.format("%d:%02d", minutes, seconds));
        }
    });
timer.start();

Or you can make a simple function like this:

// Provided 'c' is only a numeric character
int parseInt (char c) {
    return c - '0';
}

If you know it's in dd/mm/YYYY, you can do:

    $regex = '#([/d]{1,2})/([/d]{1,2})/([/d]{2,4})#';
    $match = array();
    if (preg_match($regex, $date, $match)) {
        if (strlen($match[3]) == 2) {
            $match[3] = '20' . $match[3];
        }
        return mktime(0, 0, 0, $match[2], $match[1], $match[3]);
    }
    return strtotime($date);

It will match dates in the form d/m/YY or dd/mm/YYYY (or any combination of the two)...

If you want to support more separators than just /, you can change the regex to:

    $regex = '#([\d]{1,2})[/-]([\d]{1,2})[/-]([\d]{2,4})#';

And then add any characters you want into the [/-] bit (Note, the - character needs to be last)

It isn't possible to do it the way you've defined ldap_get. However, if you define ldap_get like this:

def ldap_get ( base_dn, filter, attrs=nil, scope=LDAP::LDAP_SCOPE_SUBTREE )

Now you can:

ldap_get( base_dn, filter, X )

But now you have problem that you can't call it with the first two args and the last arg (the same problem as before but now the last arg is different).

The rationale for this is simple: Every argument in Ruby isn't required to have a default value, so you can't call it the way you've specified. In your case, for example, the first two arguments don't have default values.

As already mentioned, you can simply cast long to double. But be careful with long to double conversion because long to double is a narrowing conversion in java.

Conversion from type double to type long requires a nontrivial translation from a 64-bit floating-point value to the 64-bit integer representation. Depending on the actual run-time value, information may be lost.

e.g. following program will print 1 not 0

    long number = 499999999000000001L;
    double converted = (double) number;
    System.out.println( number - (long) converted);

Try:

this.props.router.goBack()

Look, the sed script that prints the 100 last lines you can find in the documentation for sed (https://www.gnu.org/software/sed/manual/sed.html#tail):

$ cat sed.cmd
1! {; H; g; }
1,100 !s/[^\n]*\n//
$p

$ sed -nf sed.cmd logfilename

For me it is way more difficult than your script so

tail -n 100 logfilename

is much much simpler. And it is quite efficient, it will not read all file if it is not necessary. See my answer with strace report for tail ./huge-file: https://unix.stackexchange.com/questions/102905/does-tail-read-the-whole-file/102910#102910

You can take a dump to your local machine using this command:

mongorestore -h <host>:<port> -u <username> -p <password> -d <DBNAME> /path/to/destination/directory/<DBNAME>

I have just went through the same issue and found a good solution at PHP manuals.

I changed all my file encoding to UTF8 then the default encoding on my connection. This solved all the problems.

if (!$mysqli->set_charset("utf8")) {
    printf("Error loading character set utf8: %s\n", $mysqli->error);
} else {
   printf("Current character set: %s\n", $mysqli->character_set_name());
}

View Source

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

Here is perhaps a different way for you to achieve this. Pass into the directive both the index and the item and let the directive setup the html in a template:

Demo: http://plnkr.co/edit/ybcNosdPA76J1IqXjcGG?p=preview

html:

<ul id="thumbnails">
    <li class="thumbnail" ng-repeat="item in items" options='#my-container' itemdata='item' index="$index">

    </li>
  </ul>

js directive:

app.directive('thumbnail', [function() {
  return {
    restrict: 'CA',
    replace: false,
    transclude: false,
    scope: {
        index: '=index',
        item: '=itemdata'
    },
    template: '<a href="#"><img src="{{item.src}}" alt="{{item.alt}}" /></a>',
    link: function(scope, elem, attrs) {
        if (parseInt(scope.index) == 0) {
            angular.element(attrs.options).css({'background-image':'url('+ scope.item.src +')'});
        }

        elem.bind('click', function() {
            var src = elem.find('img').attr('src');

            // call your SmoothZoom here
            angular.element(attrs.options).css({'background-image':'url('+ scope.item.src +')'});
        });
    }
}
}]);

You probably would be better off adding a ng-click to the image as pointed out in another answer.

The link for the demo was incorrect. It has been updated to: http://plnkr.co/edit/ybcNosdPA76J1IqXjcGG?p=preview

Simple ruby script based on this answer: registry_cleaner.

You can run it on local machine:

./registry_cleaner.rb --host=https://registry.exmpl.com --repository=name --tags_count=4

And then on the registry machine remove blobs with /bin/registry garbage-collect /etc/docker/registry/config.yml.

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Sub Testing()
    Dim filename As String: filename = GetFileName(Range("o1"))

    ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _
                                              filename:=filename, _
                                              Quality:=xlQualityStandard, _
                                              IncludeDocProperties:=True, _
                                              IgnorePrintAreas:=False, _
                                              OpenAfterPublish:=False
End Sub

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

Instead of using JTextArea.setText(String text), use JTextArea.append(String text).

Appends the given text to the end of the document. Does nothing if the model is null or the string is null or empty.

This will add text on to the end of your JTextArea.

Another option would be to use getText() to get the text from the JTextArea, then manipulate the String (add or remove or change the String), then use setText(String text) to set the text of the JTextArea to be the new String.

I have a lib what use https://requests.readthedocs.io/en/master/ what use https://pypi.org/project/certifi/ but I have a custom CA included in my /etc/ssl/certs.

So I solved my problem like this:

# Your TLS certificates directory (Debian like)
export SSL_CERT_DIR=/etc/ssl/certs
# CA bundle PATH (Debian like again)
export CA_BUNDLE_PATH="${SSL_CERT_DIR}/ca-certificates.crt"
# If you have a virtualenv:
. ./.venv/bin/activate
# Get the current certifi CA bundle
CERTFI_PATH=`python -c 'import certifi; print(certifi.where())'`

test -L $CERTFI_PATH || rm $CERTFI_PATH
test -L $CERTFI_PATH || ln -s $CA_BUNDLE_PATH $CERTFI_PATH

Et voilà !

You have a potential race condition in your code--what happens if the user has permissions to write to the folder when you check, but before the user actually writes to the folder this permission is withdrawn? The write will throw an exception which you will need to catch and handle. So the initial check is pointless. You might as well just do the write and handle any exceptions. This is the standard pattern for your situation.

First - most classes will never need to be thread-safe. Use YAGNI: only apply thread-safety when you know you actually are going to use it (and test it).

For the method-level stuff, there is [MethodImpl]:

[MethodImpl(MethodImplOptions.Synchronized)]
public void SomeMethod() {/* code */}

This can also be used on accessors (properties and events):

private int i;
public int SomeProperty
{
    [MethodImpl(MethodImplOptions.Synchronized)]
    get { return i; }
    [MethodImpl(MethodImplOptions.Synchronized)]
    set { i = value; }
}

Note that field-like events are synchronized by default, while auto-implemented properties are not:

public int SomeProperty {get;set;} // not synchronized
public event EventHandler SomeEvent; // synchronized

Personally, I don't like the implementation of MethodImpl as it locks this or typeof(Foo) - which is against best practice. The preferred option is to use your own locks:

private readonly object syncLock = new object();
public void SomeMethod() {
    lock(syncLock) { /* code */ }
}

Note that for field-like events, the locking implementation is dependent on the compiler; in older Microsoft compilers it is a lock(this) / lock(Type) - however, in more recent compilers it uses Interlocked updates - so thread-safe without the nasty parts.

This allows more granular usage, and allows use of Monitor.Wait/Monitor.Pulse etc to communicate between threads.

If you want to simply add all the deleted files to stage then you can use git add .

This is the easiest way right now with git v2.27.0. Note that using * and . are different approaches. Using git add * would only add currently present files whereas git add . would also stage the files deleted with rm command.

It's obvious but worth mentioning that other files which have been modified would also be added to the staging area when you use git add ..

            tr.append("<td>" + json[i].score + "</td>");
            tr.append("<td>" + json[i].team + "</td>");
            $('table').append(tr);

JSFiddle

Long story short, EOF marker(but a different literal can be used as well) is a heredoc format that allows you to provide your input as multiline. A lot of confusion comes from how cat actually works it seems. You can use cat with >> or > as follows:

$ cat >> temp.txt
line 1

While cat can be used this way when writing manually into console, it's not convenient if I want to provide the input in a more declarative way so that it can be reused by tools and also to keep indentations, whitespaces, etc.
Heredoc allows to define your entire input as if you are not working with stdin but typing in a separate text editor. This is what Wikipedia article means by:

it is a section of a source code file that is treated as if it were a separate file.

Here is the Kotlin version to get SHA encryption string.

import java.security.MessageDigest

object HashUtils {
    fun sha512(input: String) = hashString("SHA-512", input)

    fun sha256(input: String) = hashString("SHA-256", input)

    fun sha1(input: String) = hashString("SHA-1", input)

    /**

    private fun hashString(type: String, input: String): String {
        val HEX_CHARS = "0123456789ABCDEF"
        val bytes = MessageDigest
                .getInstance(type)
                .digest(input.toByteArray())
        val result = StringBuilder(bytes.size * 2)

        bytes.forEach {
            val i = it.toInt()
            result.append(HEX_CHARS[i shr 4 and 0x0f])
            result.append(HEX_CHARS[i and 0x0f])
        }

        return result.toString()
    }
}

I'm not aware of anything like a single table that lets you compare all of them in at one glance (I'm not sure such a table would even be feasible).

Of course the ISO standard document enumerates the complexity requirements in detail, sometimes in various rather readable tables, other times in less readable bullet points for each specific method.

Also the STL library reference at http://www.cplusplus.com/reference/stl/ provides the complexity requirements where appropriate.

I'm doing something similar, but in my case I'm doing serialization/De-serialization so I need to be able to go both directions. I find using a string[][] works nearly identically to the dictionary, including initialization, but you can go the other direction too, returning the substitutes to their original values, something that the dictionary really isn't set up to do.

Edit: You can use Dictionary<Key,List<Values>> in order to obtain same result as string[][]

This worked for me:

  INSERT INTO [TABLE]
  VALUES ('text','''test.com''', 1)

Basically, you take the single quote you want to insert and replace it with two. So if you want to insert a string of text ('text') and add single quotes around it, it would be ('''text'''). Hope this helps.

The simplest solution might be to limit the number of characters in the HTML itself. Rails has a truncate(string, length) helper, and I'm certain that whichever backend you're using provides something similar.

Due to the cross-browser issues you're already familiar with regarding the width of select boxes, this seems to me to be the most straightforward and least error-prone option.

<select>
  <option value="1">One</option>
  <option value="100">One hund...</option>
<select>

My Java ini files didn't have section headers and I wanted a dict as a result. So i simply injected an "[ini]" section and let the default config library do its job. The result is converted to a dict:

from configparser import ConfigParser

@staticmethod
    def readPropertyFile(path):
        # https://stackoverflow.com/questions/3595363/properties-file-in-python-similar-to-java-properties
        config = ConfigParser()
        s_config= open(path, 'r').read()
        s_config="[ini]\n%s" % s_config
        # https://stackoverflow.com/a/36841741/1497139
        config.read_string(s_config)
        items=config.items('ini')
        itemDict={}
        for key,value in items:
            itemDict[key]=value
        return itemDict

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

Maybe not as elegant but another possibility would be to write a formula to do the check and fill it in an adjacent column. You could then filter on that column.

The following looks in cell b14 and would return true for all the file types you mention. This assumes that the file extension is by itself in the column. If it's not it would be a little more complicated but you could still do it this way.

=OR(B14=".pdf",B14=".doc",B14=".docx",B14=".xls",B14=".xlsx",B14=".rtf",B14=".txt",B14=".csv",B14=".pps")

Like I said, not as elegant as the advanced filters but options are always good.

Like Edwin suggested, use snprintf:

#include <stdio.h>
int main(int argc, const char *argv[])
{
    int n = 1234;
    char buf[10];
    snprintf(buf, 10, "%d", n);
    printf("%s\n", buf);
    return 0;
}

Yes, there is a way to do this. You could use a pseudo-element after to position a block on top of your background image. Something like this: http://jsfiddle.net/Pevara/N2U6B/

The css for the :after looks like this:

#the-div:hover:after {
    content: ' ';
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    background-color: rgba(0,0,0,.5);
}

edit:
When you want to apply this to a non-empty element, and just get the overlay on the background, you can do so by applying a positive z-index to the element, and a negative one to the :after. Something like this:

#the-div {
    ...
    z-index: 1;
}
#the-div:hover:after {
    ...
    z-index: -1;
}

And the updated fiddle: http://jsfiddle.net/N2U6B/255/

In more simple terms:

Technically, the -u flag adds a tracking reference to the upstream server you are pushing to.

What is important here is that this lets you do a git pull without supplying any more arguments. For example, once you do a git push -u origin master, you can later call git pull and git will know that you actually meant git pull origin master.

Otherwise, you'd have to type in the whole command.

Using other posters code with some tweaks:

(I know I add nothing new, but the straightforward answer should be visible).

From the spring docs

Spring can be easily integrated into any Java-based web framework. All you need to do is to declare the ContextLoaderListener in your web.xml and use a contextConfigLocation to set which context files to load.

The <context-param>:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>

<listener>
   <listener-class>
        org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener> 

You can then use the WebApplicationContext to get a handle on your beans.

WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(servlet.getServletContext());
SomeBean someBean = (SomeBean) ctx.getBean("someBean");

See http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/context/support/WebApplicationContextUtils.html for more info

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

I believe this works:

$(".MyClass").length 

An example with a little less stringified html:

var container = $('#my-container'),
  table = $('<table>');

users.forEach(function(user) {
  var tr = $('<tr>');
  ['ID', 'Name', 'Address'].forEach(function(attr) {
    tr.append('<td>' + user[attr] + '</td>');
  });
  table.append(tr);
});

container.append(table);

You can see some reports in SSMS:

Right-click the instance name / reports / standard / top sessions

You can see top CPU consuming sessions. This may shed some light on what SQL processes are using resources. There are a few other CPU related reports if you look around. I was going to point to some more DMVs but if you've looked into that already I'll skip it.

You can use sp_BlitzCache to find the top CPU consuming queries. You can also sort by IO and other things as well. This is using DMV info which accumulates between restarts.

This article looks promising.

Some stackoverflow goodness from Mr. Ozar.

edit: A little more advice... A query running for 'only' 5 seconds can be a problem. It could be using all your cores and really running 8 cores times 5 seconds - 40 seconds of 'virtual' time. I like to use some DMVs to see how many executions have happened for that code to see what that 5 seconds adds up to.

Change the key of the component.

<Component key="1" />

<Component key="2" />

Component will be unmounted and a new instance of Component will be mounted since the key has changed.

edit: Documented on You Probably Don't Need Derived State:

When a key changes, React will create a new component instance rather than update the current one. Keys are usually used for dynamic lists but are also useful here.

If you (or a helpful admin) runs Set-ExecutionPolicy as administrator, the policy will be set for all users. (I would suggest "remoteSigned" rather than "unrestricted" as a safety measure.)

NB.: On a 64-bit OS you need to run Set-ExecutionPolicy for 32-bit and 64-bit PowerShell separately.

 WebConfigurationManager.ConnectionStrings["YourConnectionString"].ProviderName;

Simply replace it with nothing:

var string = 'F0123456'; // just an example
string.replace(/^F0+/i, ''); '123456'

There is no cross-browser way of styling option elements, certainly not to the extent of your second screenshot. You might be able to make them bold, and set the font-size, but that will be about it...

This is just fine but if you add option which is not in optgroup it gets buggy.

<select>_x000D_
  <optgroup label="Level One">_x000D_
    <option> A.1 </option>_x000D_
    <optgroup label="&nbsp;&nbsp;&nbsp;&nbsp;Level Two">_x000D_
      <option>&nbsp;&nbsp;&nbsp;&nbsp; A.B.1 </option>_x000D_
    </optgroup>_x000D_
    <option> A.2 </option>_x000D_
  </optgroup>_x000D_
  <option> A </option>_x000D_
</select>

Would be much better if you used css and close optgroup right away :

<select>_x000D_
  <optgroup label="Level One"></optgroup>_x000D_
  <option style="padding-left:15px"> A.1 </option>_x000D_
  <optgroup label="Level Two" style="padding-left:15px"></optgroup>_x000D_
  <option style="padding-left:30px"> A.B.1 </option>_x000D_
  <option style="padding-left:15px"> A.2 </option>_x000D_
  <option> A </option>_x000D_
</select>

This post describes it very nicely.

In short: utf8_unicode_ci uses the Unicode Collation Algorithm as defined in the Unicode standards, whereas utf8_general_ci is a more simple sort order which results in "less accurate" sorting results.

You can think of serialization as the process of converting an object instance into a sequence of bytes (which may be binary or not depending on the implementation).

It is very useful when you want to transmit one object data across the network, for instance from one JVM to another.

In Java, the serialization mechanism is built into the platform, but you need to implement the Serializable interface to make an object serializable.

You can also prevent some data in your object from being serialized by marking the attribute as transient.

Finally you can override the default mechanism, and provide your own; this may be suitable in some special cases. To do this, you use one of the hidden features in java.

It is important to notice that what gets serialized is the "value" of the object, or the contents, and not the class definition. Thus methods are not serialized.

Here is a very basic sample with comments to facilitate its reading:

import java.io.*;
import java.util.*;

// This class implements "Serializable" to let the system know
// it's ok to do it. You as programmer are aware of that.
public class SerializationSample implements Serializable {

    // These attributes conform the "value" of the object.

    // These two will be serialized;
    private String aString = "The value of that string";
    private int    someInteger = 0;

    // But this won't since it is marked as transient.
    private transient List<File> unInterestingLongLongList;

    // Main method to test.
    public static void main( String [] args ) throws IOException  { 

        // Create a sample object, that contains the default values.
        SerializationSample instance = new SerializationSample();

        // The "ObjectOutputStream" class has the default 
        // definition to serialize an object.
        ObjectOutputStream oos = new ObjectOutputStream( 
                               // By using "FileOutputStream" we will 
                               // Write it to a File in the file system
                               // It could have been a Socket to another 
                               // machine, a database, an in memory array, etc.
                               new FileOutputStream(new File("o.ser")));

        // do the magic  
        oos.writeObject( instance );
        // close the writing.
        oos.close();
    }
}

When we run this program, the file "o.ser" is created and we can see what happened behind.

If we change the value of: someInteger to, for example Integer.MAX_VALUE, we may compare the output to see what the difference is.

Here's a screenshot showing precisely that difference:

_{Can you spot the differences? ;)}

There is an additional relevant field in Java serialization: The serialversionUID but I guess this is already too long to cover it.

As of woocommerce 3.0

$order->id;

will not work, it will generate notice, use getter function:

$order->get_id();

The same applies for other woocommerce objects like procut.

I don't recommend StartNew unless you need that level of complexity.

If your async method is dependent on other async methods, the easiest approach is to use the async keyword:

private static async Task<DateTime> CountToAsync(int num = 10)
{
  for (int i = 0; i < num; i++)
  {
    await Task.Delay(TimeSpan.FromSeconds(1));
  }

  return DateTime.Now;
}

If your async method is doing CPU work, you should use Task.Run:

private static async Task<DateTime> CountToAsync(int num = 10)
{
  await Task.Run(() => ...);
  return DateTime.Now;
}

You may find my async/await intro helpful.

Had the same problem. For me it worked to call

viewPage.setAdapter( adapter );

again which caused reinstantiating the pages again.

While it is possible to combine the results, I would advise against doing so.

You have two fundamentally different types of queries that return a different number of rows, a different number of columns and different types of data. It would be best to leave it as it is - two separate queries.

It depends on what you are after in the Dictionary

Models.TestModels obj = new Models.TestModels();

foreach (var keyValuPair in obj.sp)
{
    // KeyValuePair<int, dynamic>
}

foreach (var key in obj.sp.Keys)
{
     // Int 
}

foreach (var value in obj.sp.Values)
{
    // dynamic
}

Why not just use simple javascript?

var array=[1,2,3,4];
var lastEl = array[array.length-1];

You can write it as a method too, if you like (assuming prototype has not been included on your page):

Array.prototype.last = function() {return this[this.length-1];}

If you want to kill the Sticky Service,the following command NOT WORKING:

adb shell am force-stop <PACKAGE>
adb shell kill <PID>

The following command is WORKING:

adb shell pm disable <PACKAGE>

If you want to restart the app,you must run command below first:

adb shell pm enable <PACKAGE>

Specify a 'display-image' and 'full-size-image' as described here: http://www.informit.com/articles/article.aspx?p=1829415&seqNum=16

iOS8 requires these images

Here's my working Async Pure Javascript from 2020

function testFileExists(src, successFunc, failFunc) {
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function () {
        if (this.readyState === this.DONE) {
            if (xhr.status === 200) {
                successFunc(xhr);
            } else {
                failFunc(xhr);
            }
        }
    }
    // xhr.error = function() {
    //     failFunc(xhr);
    // }
    // xhr.onabort = function() {
    //     failFunc(xhr);
    // }
    // xhr.timeout = function() {
    //     failFunc(xhr);
    // }
    xhr.timeout = 5000;           // TIMEOUT SET TO PREFERENCE (5 SEC)
    xhr.open('HEAD', src, true);
    xhr.send(null);               // VERY IMPORTANT
}
function fileExists(xhr) {
    alert("File exists !!  Yay !!");
}
function fileNotFound(xhr) {
    alert("Cannot find the file, bummer");
}
testFileExists("test.html", fileExists, fileNotFound);

I could not force it to come back with any of the abort, error, or timeout callbacks. Each one of these returned a main status code of 0, in the test above, so I removed them. You can experiment. I set the timeout to 5 seconds as the default seems to be very excessive. With the Async call, it doesn't seem to do anything without the send() command.

I was having same problem and I resolved the issue. Earlier css was overflow:hidden; z-index:999999;

I change it to overflow:visible;

You can try these:

function union(a, b) {
    return a.concat(b).reduce(function(prev, cur) {
        if (prev.indexOf(cur) === -1) prev.push(cur);
        return prev;
    }, []);    
}

or

function union(a, b) {
    return a.concat(b.filter(function(el) {
        return a.indexOf(el) === -1;
    }));
}

is compares identity. A string will never be identical to a not-string.

== is equality. But a string will never be equal to either True or False.

You want neither.

path = '/bla/bla/bla'

if path:
    print "True"
else:
    print "False"

It was fixed when I removed settings.xml from .m2 folder.

This works for me using enzyme 2.4.1:

const wrapper = mount(<EditableText defaultValue="Hello" />);
const input = wrapper.find('input');

console.log(input.node.value);

Log4j by default looks for a file called log4j.properties or log4j.xml on the classpath.

You can control which file it uses to initialize itself by setting system properties as described here (Look for the "Default Initialization Procedure" section).

For example:

java -Dlog4j.configuration=customName ....

Will cause log4j to look for a file called customName on the classpath.

If you are having problems I find it helpful to turn on the log4j.debug:

-Dlog4j.debug

It will print to System.out lots of helpful information about which file it used to initialize itself, which loggers / appenders got configured and how etc.

The configuration file can be a java properties file or an xml file. Here is a sample of the properties file format taken from the log4j intro documentation page:

log4j.rootLogger=debug, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender

In the spring boot reference,it said:

When a class doesn’t include a package declaration it is considered to be in the “default package”. The use of the “default package” is generally discouraged, and should be avoided. It can cause particular problems for Spring Boot applications that use @ComponentScan, @EntityScan or @SpringBootApplication annotations, since every class from every jar, will be read.

com
 +- example
     +- myproject
         +- Application.java
         |
         +- domain
         |   +- Customer.java
         |   +- CustomerRepository.java
         |
         +- service
         |   +- CustomerService.java
         |
         +- web
             +- CustomerController.java

In your cases. You must add scanBasePackages in the @SpringBootApplication annotation.just like@SpringBootApplication(scanBasePackages={"domain","contorller"..})

I tried this in Python 3 , seems to work fine .

a, b = map(int,input().split())

print(a)

print(b)

Input : 3 44

Output :

3

44

I recorded a macro and I found it in %APPDATA%\Notepad++\shortcuts.xml. It looks like posted in the first post of this thread.

I use NPP Ver. 5.9.6.2 with Win7.

Other answers indicate perfectly well that --no-ff results in a merge commit. This retains historical information about the feature branch which is useful since feature branches are regularly cleaned up and deleted.

This answer may provide context for when to use or not to use --no-ff.

Merging from feature into the main branch: use --no-ff

Worked example:

$ git checkout -b NewFeature
[work...work...work]
$ git commit -am  "New feature complete!"
$ git checkout main
$ git merge --no-ff NewFeature
$ git push origin main
$ git branch -d NewFeature

Merging changes from main into feature branch: leave off --no-ff

Worked example:

$ git checkout -b NewFeature
[work...work...work]
[New changes made for HotFix in the main branch! Lets get them...]
$ git commit -am  "New feature in progress"
$ git pull origin main
[shortcut for "git fetch origin main", "git merge origin main"]

Consider using strtok_r, as others have suggested, or something like:

void printWords(const char *string) {
    // Make a local copy of the string that we can manipulate.
    char * const copy = strdup(string);
    char *space = copy;
    // Find the next space in the string, and replace it with a newline.
    while (space = strchr(space,' ')) *space = '\n';
    // There are no more spaces in the string; print out our modified copy.
    printf("%s\n", copy);
    // Free our local copy
    free(copy);
}

Try To Give Full path for reading image.

Example image = ImageIO.read(new File("D:/work1/Jan14Stackoverflow/src/Strawberry.jpg"));

your code is not producing any exception after giving the full path. If you want to just read an image file in java code. Refer the following - http://docs.oracle.com/javase/tutorial/2d/images/examples/LoadImageApp.java

If the object of your class is created at end your code works fine for me and displays the image

// PracticeFrame pframe = new PracticeFrame();//comment this

new PracticeFrame().add(panel);

The difference is ternary operator

• You can use

return condition ? someData : Promise.reject(new Error('not OK'))

• You can't use

return condition ? someData  : throw new Error('not OK')

Chrome (and maybe other webkit browsers) only:

/* you probably want to specify the size if you're going to disable the scrollbar */_x000D_
select[size]::-webkit-scrollbar {_x000D_
 display: none;_x000D_
}

<select size=4>_x000D_
  <option>Mango</option>_x000D_
  <option>Peach</option>_x000D_
  <option>Orange</option>_x000D_
  <option>Banana</option>_x000D_
</select>

My scenario was different after I tested all the possible options. If you have changed the ports and still get the same problem, well here's something you can try out. This was done in Windows 7.

Step 1: Confirm the cause of the error by going to Control Panel -> System and Security -> Administrative Tools -> Event Viewer -> Windows Logs -> Application -> Error. Mine said "The Apache service named reported the following error:

httpd.exe: Syntax error on line 424 of C:/xampp/apache/conf/httpd.conf: Cannot load c:\xampp\php\php5apache.dll into server: The specified module could not be found." So I needed to change \php5apache.dll to the version of my php and apache version installed which was php7apache2_4.dll

Step 2: To get the correct name for your .dll php and apache file, got to C:\xampp\php. You will see something like php7apache2_4.dll with other files in the folder.

Step 3: Go to C:/xampp/apache/conf/httpd.conf and edit the configuration file and change "c:\xampp\php\php5apache.dll" to "c:\xampp\php\php7apache2_4.dll" in my case. Make sure you open the file as administrator save changes made.

Step 4: Run the xampp server and everything should work fine. Do not forget to shut down the xampp server before doing the changes to the apache configuration file.

Hope this helps. Cheers! :)

For bash, Bourne shell and fish:

curl -s http://server/path/script.sh | bash -s arg1 arg2

Flag "-s" makes shell read from stdin.

You can try use in javascript:

window.onload = function() {
 alert("let's go!");
}

Its a good practice separate javascript of html

For the current date activity and complete activity for previous 30 days use this, since the SYSDATE is variable in a day the previous 30th day will not have the whole data for that day.

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM mytable
WHERE create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND SYSDATE()

m,n=map(int,input().split()) # m - number of rows; n - number of columns;

matrix = [[int(j) for j in input().split()[:n]] for i in range(m)]

for i in matrix:print(i)

You can also do something like:

SELECT COUNT(DISTINCT id + name + address) FROM mytable

Using either a float or a double value in a C expression will result in a value that is a double anyway, so printf can't tell the difference. Whereas a pointer to a double has to be explicitly signalled to scanf as distinct from a pointer to float, because what the pointer points to is what matters.

Firstly a warning: you should never tinker with DOM that is managed by React, which you are doing by calling ReactDOM.render(<SampleComponent ... />);

With React, you should use SampleComponent directly in the main App.

var App = require('./App.js');
var SampleComponent = require('./SampleComponent.js');
ReactDOM.render(<App/>, document.body);

The content of your Component is irrelevant, but it should be used like this:

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component! </h1>
                <SampleComponent name="SomeName"/>
            </div>
        );
    }
});

You can then extend your app component to use a list.

var App = React.createClass({
    render: function() {
        var componentList = [
            <SampleComponent name="SomeName1"/>,
            <SampleComponent name="SomeName2"/>
        ]; // Change this to get the list from props or state
        return (
            <div>
                <h1>App main component! </h1>
                {componentList}
            </div>
        );
    }
});

I would really recommend that you look at the React documentation then follow the "Get Started" instructions. The time you spend on that will pay off later.

Might not work you for, but a technique I've used a couple times in the past for similar circumstances.

created updated_{table_name}, then select insert into this table in batches. Once finished, and this hinges on Oracle ( which I don't know or use ) supporting the ability to rename tables in an atomic fashion. updated_{table_name} becomes {table_name} while {table_name} becomes original_{table_name}.

Last time I had to do this was for a heavily indexed table with several million rows that absolutely positively could not be locked for the duration needed to make some serious changes to it.

Try this.

HTML

<!-- Your table -->
<table width="100%" border="0" cellspacing="0" cellpadding="0" id="table-data"> 
    <thead>
        <tr>
            <th>Name</th>
            <th>Location</th>
            <th>From</th>
            <th>To</th>
            <th>Add</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td><input type="text" autofocus placeholder="who" name="who" ></td>
            <td><input type="text" autofocus placeholder="location" name="location" ></td>
            <td><input type="text" placeholder="Start Date" name="datepicker_start" class="datepicker"></td>
            <td><input type="text" placeholder="End Date" name="datepicker_end" class="datepicker"></td>
            <td><input type="button" name="add" value="Add" class="tr_clone_add"></td>
        </tr>
    <tbody>
</table>

<!-- Model of new row -->
<table id="new-row-model" style="display: none"> 
    <tbody>
        <tr>
            <td><input type="text" autofocus placeholder="who" name="who" ></td>
            <td><input type="text" autofocus placeholder="location" name="location" ></td>
            <td><input type="text" placeholder="Start Date" name="datepicker_start" class="datepicker"></td>
            <td><input type="text" placeholder="End Date" name="datepicker_end" class="datepicker"></td>
            <td><input type="button" name="add" value="Add" class="tr_clone_add"></td>
        </tr>
    <tbody>
</table>

Script

$("input.tr_clone_add").live('click', function(){
    var new_row = $("#new-row-model tbody").clone();
    $("#table-data tbody").append(new_row.html());
});

If your clustered index consist from only those fields than the simple, fast and reliable option is to use IGNORE_DUP_KEY

If you create the Clustered index with IGNORE_DUP_KEY ON

Than you can just use:

INSERT INTO EmailsRecebidos (De, Assunto, Data) VALUES (@_DE, @_ASSUNTO, @_DATA)

This should be safe in all cases!

If you are using GCP then you have to set workers per instance type.

Using transform in combination with transition works flawlessly for me:

.ani-grow {
    -webkit-transition: all 0.5s ease; 
    -moz-transition: all 0.5s ease; 
    -o-transition: all 0.5s ease; 
    -ms-transition: all 0.5s ease; 
    transition: all 0.5s ease; 
}
.ani-grow:hover {
    transform: scale(1.01);
}

by splitting with newlines.

for line in wallop_of_a_string_with_many_lines.split('\n'):
  #do_something..

if you iterate over a string, you are iterating char by char in that string, not by line.

>>>string = 'abc'
>>>for line in string:
    print line

a
b
c

Don't make data frames. Keep the list, name its elements but do not attach it.

The biggest reason for this is that if you make variables on the go, almost always you will later on have to iterate through each one of them to perform something useful. There you will again be forced to iterate through each one of the names that you have created on the fly.

It is far easier to name the elements of the list and iterate through the names.

As far as attach is concerned, its really bad programming practice in R and can lead to a lot of trouble if you are not careful.

We can also use str_extract from stringr

years<-c("20 years old", "1 years old")
as.integer(stringr::str_extract(years, "\\d+"))
#[1] 20  1

If there are multiple numbers in the string and we want to extract all of them, we may use str_extract_all which unlike str_extract returns all the macthes.

years<-c("20 years old and 21", "1 years old")
stringr::str_extract(years, "\\d+")
#[1] "20"  "1"

stringr::str_extract_all(years, "\\d+")

#[[1]]
#[1] "20" "21"

#[[2]]
#[1] "1"

To conditionally control view of Template/Command fields, use RowDataBound event of Gridview, like:

    <asp:GridView ID="gv1" OnRowDataBound="gv1_RowDataBound"
              runat="server" AutoGenerateColumns="False" DataKeyNames="Id" >
    <Columns>   
        ...        
           <asp:TemplateField HeaderText="Order Status" 
HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"> 
                 <ItemTemplate> 
                       <asp:Label ID="lblOrderStatus" runat="server"
Text='<%# Bind("OrderStatus") %>'></asp:Label> 
                 </ItemTemplate>
                 <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                 <ItemStyle HorizontalAlign="Center"></ItemStyle>
           </asp:TemplateField>  
        ...

            <asp:CommandField ShowSelectButton="True" SelectText="Select" />

    </Columns>
                </asp:GridView>

and following:

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        Label lblOrderStatus=(Label) e.Row.Cells[4].FindControl("lblOrderStatus");

        if (lblOrderStatus.Text== "Ordered")
        {
            lblOrderStatus.ForeColor = System.Drawing.Color.DarkBlue;
            LinkButton bt = (LinkButton)e.Row.Cells[5].Controls[0];
            bt.Visible = false;
            e.Row.BackColor = System.Drawing.Color.LightGray;
        }
    }

JAVA APP

@OnEditorAction(R.id.textinput)
boolean onEditorAction(int actionId, KeyEvent key){
    boolean handled = false;
    if (actionId == EditorInfo.IME_ACTION_SEND || (key.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
        //do whatever you want
        handled = true;
    }
    return handled;
}

Simplest solution seems to be specifying the ylim range. Here is some code to do this automatically (left default, right - adjusted):

# default y-axis
barplot(dat, beside=TRUE)

# automatically adjusted y-axis
barplot(dat, beside=TRUE, ylim=range(pretty(c(0, dat))))

The trick is to use pretty() which returns a list of interval breaks covering all values of the provided data. It guarantees that the maximum returned value is 1) a round number 2) greater than maximum value in the data.

In the example 0 was also added pretty(c(0, dat)) which makes sure that axis starts from 0.

Yes, there is. The difference is in the return value. The return value of "++i" will be the value after incrementing i. The return of "i++" will be the value before incrementing. This means that code that looks like the following:

int a = 0;
int b = ++a; // a is incremented and the result after incrementing is saved to b.
int c = a++; // a is incremented again and the result before incremening is saved to c.

Therefore, a would be 2, and b and c would each be 1.

I could rewrite the code like this:

int a = 0; 

// ++a;
a = a + 1; // incrementing first.
b = a; // setting second. 

// a++;
c = a; // setting first. 
a = a + 1; // incrementing second. 

Looks like you want git diff and/or git log. Also check out gitk

gitk path/to/file
git diff path/to/file
git log path/to/file

For example:

let myString = "Hello World"
let myMatch = myString.match(/H.*/)
console.log(myMatch)

Or

let myString = "Hello World"
let myVariable = "H"
let myReg = new RegExp(myVariable + ".*")
let myMatch = myString.match(myReg)
console.log(myMatch)

Vanilla Javascript Answer

var c = document.getElementById("myElement").getBoundingClientRect();
var bot = c.bottom;
var rgt = c.right;

To be clear the element can be anything so long as you have allocated an id to it <img> <div> <p> etc.

for example

<img
    id='myElement'
    src='/img/logout.png'
    className='logoutImg img-button'
    alt='Logout'
/>

I have a 7GB SQLite database. To perform a particular query with an inner join takes 2.6s In order to speed this up I tried adding indexes. Depending on which index(es) I added, sometimes the query went down to 0.1s and sometimes it went UP to as much as 7s. I think the problem in my case was that if a column is highly duplicate then adding an index degrades performance :(

In your example number is a primitive, so will be stored as a value.

If you want to use a reference then you should use one of the wrapper types (e.g. Integer)

I've created a simple library for handling optional arguments with JavaScript functions, see https://github.com/ovatto/argShim. The library is developed with Node.js in mind but should be easily ported to work with e.g. browsers.

Example:

var argShim = require('argShim');
var defaultOptions = {
  myOption: 123
};

var my_function = argShim([
    {optional:'String'},
    {optional:'Object',default:defaultOptions}
  ], function(content, options) {
    console.log("content:", content, "options:", options);
  });

my_function();
my_function('str');
my_function({myOption:42});
my_function('str', {myOption:42});

Output:

content: undefined options: { myOption: 123 }
content: str options: { myOption: 123 }
content: undefined options: { myOption: 42 }
content: str options: { myOption: 42 }

The main target for the library are module interfaces where you need to be able to handle different invocations of exported module functions.

I used this method:

$(document).mousemove(function(e) {
    window.x = e.pageX;
    window.y = e.pageY;
});

function show_popup(str) {
    $("#popup_content").html(str);
    $("#popup").fadeIn("fast");
    $("#popup").css("top", y);
    $("#popup").css("left", x);
}

In this way I'll always have the distance from the top saved in y and the distance from the left saved in x.

On Windows I use this code:

void * G_pPointer = NULL;
const char * G_szPointerName = NULL;
void CheckPointerIternal()
{
    char cTest = *((char *)G_pPointer);
}
bool CheckPointerIternalExt()
{
    bool bRet = false;

    __try
    {
        CheckPointerIternal();
        bRet = true;
    }
    __except (EXCEPTION_EXECUTE_HANDLER)
    {
    }

    return  bRet;
}
void CheckPointer(void * A_pPointer, const char * A_szPointerName)
{
    G_pPointer = A_pPointer;
    G_szPointerName = A_szPointerName;
    if (!CheckPointerIternalExt())
        throw std::runtime_error("Invalid pointer " + std::string(G_szPointerName) + "!");
}

Usage:

unsigned long * pTest = (unsigned long *) 0x12345;
CheckPointer(pTest, "pTest"); //throws exception

Just add this to your local.properties file of your project:

BUILD_DIR=C\:\\Tmp

(The error in Windows is due a long path, so I gave the path to one temporary folder.)

I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:

1) I set up a form so I can use a POST method.

2) When the user is done drawing, he can click the "Save" button.

3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.

document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();

4) When the form is submited I have this small php script:

<?php 
$upload_dir = somehow_get_upload_dir();  //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>

You can also use function:

//Works with negative numbers now
static int MyRound(double d) {
  if (d < 0) {
    return (int)(d - 0.5);
  }
  return (int)(d + 0.5);
}

Depending on the architecture it is several times faster.

if (element.nodeName == "A") {
 ...
} else if (element.nodeName == "TD") {
 ...
}

Use finish like this:

Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish();  //Kill the activity from which you will go to next activity 
startActivity(i);

FLAG_ACTIVITY_NO_HISTORY you can use in case for the activity you want to finish. For exampe you are going from A-->B--C. You want to finish activity B when you go from B-->C so when you go from A-->B you can use this flag. When you go to some other activity this activity will be automatically finished.

To learn more on using Intent.FLAG_ACTIVITY_NO_HISTORY read: http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NO_HISTORY

I feel like an advanced necromancer here, but this is still an issue 4 years later in MVC5.

To handle ajax requests properly the anti-forgery token needs to be passed to the server on ajax calls. Integrating it into your post data and models is messy and unnecessary. Adding the token as a custom header is clean and reusable - and you can configure it so you don't have to remember to do it every time.

There is an exception - Unobtrusive ajax does not need special treatment for ajax calls. The token is passed as usual in the regular hidden input field. Exactly the same as a regular POST.

_Layout.cshtml

In _layout.cshtml I have this JavaScript block. It doesn't write the token into the DOM, rather it uses jQuery to extract it from the hidden input literal that the MVC Helper generates. The Magic string that is the header name is defined as a constant in the attribute class.

<script type="text/javascript">
    $(document).ready(function () {
        var isAbsoluteURI = new RegExp('^(?:[a-z]+:)?//', 'i');
        //http://stackoverflow.com/questions/10687099/how-to-test-if-a-url-string-is-absolute-or-relative

        $.ajaxSetup({
            beforeSend: function (xhr) {
                if (!isAbsoluteURI.test(this.url)) {
                    //only add header to relative URLs
                    xhr.setRequestHeader(
                       '@.ValidateAntiForgeryTokenOnAllPosts.HTTP_HEADER_NAME', 
                       $('@Html.AntiForgeryToken()').val()
                    );
                }
            }
        });
    });
</script>

Note the use of single quotes in the beforeSend function - the input element that is rendered uses double quotes that would break the JavaScript literal.

Client JavaScript

When this executes the beforeSend function above is called and the AntiForgeryToken is automatically added to the request headers.

$.ajax({
  type: "POST",
  url: "CSRFProtectedMethod",
  dataType: "json",
  contentType: "application/json; charset=utf-8",
  success: function (data) {
    //victory
  }
});

Server Library

A custom attribute is required to process the non standard token. This builds on @viggity's solution, but handles unobtrusive ajax correctly. This code can be tucked away in your common library

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public class ValidateAntiForgeryTokenOnAllPosts : AuthorizeAttribute
{
    public const string HTTP_HEADER_NAME = "x-RequestVerificationToken";

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        var request = filterContext.HttpContext.Request;

        //  Only validate POSTs
        if (request.HttpMethod == WebRequestMethods.Http.Post)
        {

            var headerTokenValue = request.Headers[HTTP_HEADER_NAME];

            // Ajax POSTs using jquery have a header set that defines the token.
            // However using unobtrusive ajax the token is still submitted normally in the form.
            // if the header is present then use it, else fall back to processing the form like normal
            if (headerTokenValue != null)
            {
                var antiForgeryCookie = request.Cookies[AntiForgeryConfig.CookieName];

                var cookieValue = antiForgeryCookie != null
                    ? antiForgeryCookie.Value
                    : null;

                AntiForgery.Validate(cookieValue, headerTokenValue);
            }
            else
            {
                new ValidateAntiForgeryTokenAttribute()
                    .OnAuthorization(filterContext);
            }
        }
    }
}

Server / Controller

Now you just apply the attribute to your Action. Even better you can apply the attribute to your controller and all requests will be validated.

[HttpPost]
[ValidateAntiForgeryTokenOnAllPosts]
public virtual ActionResult CSRFProtectedMethod()
{
  return Json(true, JsonRequestBehavior.DenyGet);
}

tr:not(:contains(.... work for me

function busca(busca){
    $("#listagem tr:not(:contains('"+busca+"'))").css("display", "none");
    $("#listagem tr:contains('"+busca+"')").css("display", "");
}

I think a more flexible option would be to wrap the Text() with Align() like so:

Align(
  alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
  child: Text("My Text"),
),

Using Center() seems to ignore TextAlign entirely on the Text widget. It will not align TextAlign.left or TextAlign.right if you try, it will remain in the center.

This will print stars in triangle:

`   
public class printstar{
public static void main (String args[]){
int m = 0;
for(int i=1;i<=4;i++){
for(int j=1;j<=4-i;j++){
System.out.print("");}

for (int n=0;n<=i+m;n++){
if (n%2==0){
System.out.print("*");}
else {System.out.print(" ");}
}
m = m+1;
System.out.println("");
}
}
}'

Reading and understanding this should help you with designing the logic next time..

Consider also .attr()

$("#roommate_but").attr("disabled", true); worked for me.

I have MinGW and also mingw32-make.exe in my bin in the C:\MinGW\bin . same other I add bin path to my windows path. After that I change it's name to make.exe . Now I can Just write command "make" in my Makefile direction and execute my Makefile same as Linux.

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

HashMap is unordered per the second line of the documentation:

This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.

Perhaps you can do as aix suggests and use a LinkedHashMap, or another ordered collection. This link can help you find the most appropriate collection to use.

You can remove your current installed jre and add the jdk by specifying the path to where the jdk is installed.

I determined that this problem was a corrupt connection manager by identifying the specific connection that was failing. I'm working in SQL Server 2016 and I have created the SSISDB catalog and I am deploying my projects there.

Here's the short answer. Delete the connection manager and then re-create it with the same name. Make sure the packages using that connection are still wired up correctly and you should be good to go. If you're not sure how to do that, I've included the detailed procedure below.

To identify the corrupt connection, I did the following. In SSMS, I opened the Integration Services Catalogs folder, then the SSISDB folder, then the folder for my solution, and on down until I found my list of packages for that project.

By right clicking the package that failed, going to reports>standard reports>all executions, selecting the last execution, and viewing the "All Messages" report I was able to isolate which connection was failing. In my case, the connection manager to my destination. I simply deleted the connection manager and then recreated a new connection manager with the same name.

Subsequently, I went into my package, opened the data flow, found that some of my destinations had lit up with the red X. I opened the destination, re-selected the correct connection name, re-selected the target table, and checked the mappings were still correct. I had six destinations and only three had the red X but I clicked all of them and made sure they were still configured correctly.

This should get you started: Using VBA in your own Excel workbook, have it prompt the user for the filename of their data file, then just copy that fixed range into your target workbook (that could be either the same workbook as your macro enabled one, or a third workbook). Here's a quick vba example of how that works:

' Get customer workbook...
Dim customerBook As Workbook
Dim filter As String
Dim caption As String
Dim customerFilename As String
Dim customerWorkbook As Workbook
Dim targetWorkbook As Workbook

' make weak assumption that active workbook is the target
Set targetWorkbook = Application.ActiveWorkbook

' get the customer workbook
filter = "Text files (*.xlsx),*.xlsx"
caption = "Please Select an input file "
customerFilename = Application.GetOpenFilename(filter, , caption)

Set customerWorkbook = Application.Workbooks.Open(customerFilename)

' assume range is A1 - C10 in sheet1
' copy data from customer to target workbook
Dim targetSheet As Worksheet
Set targetSheet = targetWorkbook.Worksheets(1)
Dim sourceSheet As Worksheet
Set sourceSheet = customerWorkbook.Worksheets(1)

targetSheet.Range("A1", "C10").Value = sourceSheet.Range("A1", "C10").Value

' Close customer workbook
customerWorkbook.Close

When you create a stored routine that has a BEGIN...END block, statements within the block are terminated by semicolon (;). But the CREATE PROCEDURE statement also needs a terminator. So it becomes ambiguous whether the semicolon within the body of the routine terminates CREATE PROCEDURE, or terminates one of the statements within the body of the procedure.

The way to resolve the ambiguity is to declare a distinct string (which must not occur within the body of the procedure) that the MySQL client recognizes as the true terminator for the CREATE PROCEDURE statement.

You can use find function in your Form class. If you want to cast (Label) ,(TextView) ... etc, in this way you can use special features of objects. It will be return Label object.

(Label)this.Controls.Find(name,true)[0];

name: item name of searched item in the form

true: Search all Children boolean value

I have found it satisfactory to use ls and cd within ipython notebook to find the file. Then type cat your_file_name into the cell, and you'll get back the contents of the file, which you can then paste into the cell as code.

Building on rcar's answer, you have to make sure a substring of the target isn't found.

if a%X%==a%PATH% echo %X% is in PATH
echo %PATH% | find /c /i ";%X%"
if errorlevel 1 echo %X% is in PATH
echo %PATH% | find /c /i "%X%;"
if errorlevel 1 echo %X% is in PATH

A fairly portable way of doing it is with the raw escape sequences. See http://en.wikipedia.org/wiki/ANSI_escape_code

Java doesn't "handle the codes", that's true, but Java outputs what you told it to output. it's not Java's fault that the Windows console treats ESC (chr(27)) as just another glyph (?).

Try to change z-index value for .modal and .modal-backdrop less than .datepicker z-index value.

+1 means 2 days ago. It's rounded.

Try the below code:

Sub opendfiles()

Dim myfile As Variant
Dim counter As Integer
Dim path As String

myfolder = "D:\temp\"
ChDir myfolder
myfile = Application.GetOpenFilename(, , , , True)
counter = 1
If IsNumeric(myfile) = True Then
    MsgBox "No files selected"
End If
While counter <= UBound(myfile)
    path = myfile(counter)
    Workbooks.Open path
    counter = counter + 1
Wend

End Sub

I would suggest to watch model value and update it upon chage: http://plnkr.co/edit/Mb0uRyIIv1eK8nTg3Qng?p=preview

The only interesting issue is with spaces: In AngularJS 1.0.3 ng-model on input automatically trims string, so it does not detect that model was changed if you add spaces at the end or at start (so spaces are not automatically removed by my code). But in 1.1.1 there is 'ng-trim' directive that allows to disable this functionality (commit). So I've decided to use 1.1.1 to achieve exact functionality you described in your question.

Use FileInfo.Exists Property:

DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles("*.xml");
if (TXTFiles.Length == 0)
{
    log.Info("no files present")
}
foreach (var fi in TXTFiles)
    log.Info(fi.Exists);

or File.Exists Method:

string curFile = @"c:\temp\test.txt";
Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");

my datagridview is editonEnter mode . so it refresh only after i leave cell or after i revisit and exit cell twice.

to trigger this iimedately . i unfocus from datagridview . then refocus it.

 this.SelectNextControl(dgv1,true,true,false,true);    
 Application.DoEvents();    //this does magic
 dgv1.Focus();

As it was mentioned before - you can't modify original list, but you can stream, modify and collect items into new list. Here is simple example how to modify string element.

public class StreamTest {

    @Test
    public void replaceInsideStream()  {
        List<String> list = Arrays.asList("test1", "test2_attr", "test3");
        List<String> output = list.stream().map(value -> value.replace("_attr", "")).collect(Collectors.toList());
        System.out.println("Output: " + output); // Output: [test1, test2, test3]
    }
}

Random Samples and Permutations ina dataframe If it is in matrix form convert into data.frame use the sample function from the base package indexes = sample(1:nrow(df1), size=1*nrow(df1)) Random Samples and Permutations

You have declared an array that can store 8 elements not 9.

this.posStatus = new int[8]; 

It means postStatus will contain 8 elements from index 0 to 7.

You can rename the table in question, create a table with an identical schema, and then drop the original table at your leisure.

See the MySQL 5.1 Reference Manual for the [RENAME TABLE][1] and [CREATE TABLE][2] commands.

RENAME TABLE tbl TO tbl_old;

CREATE TABLE tbl LIKE tbl_old;

DROP TABLE tbl_old; -- at your leisure

This approach can help minimize application downtime.
