It's fairly simple. You write values using keys and expiry times. You get values using keys. You can expire keys from the system.

Most clients follow the same rules. You can read the generic instructions and best practices on the memcached homepage.

If you really want to dig into it, I'd look at the source. Here's the header comment:

"""
client module for memcached (memory cache daemon)

Overview
========

See U{the MemCached homepage<http://www.danga.com/memcached>} for more about memcached.

Usage summary
=============

This should give you a feel for how this module operates::

    import memcache
    mc = memcache.Client(['127.0.0.1:11211'], debug=0)

    mc.set("some_key", "Some value")
    value = mc.get("some_key")

    mc.set("another_key", 3)
    mc.delete("another_key")

    mc.set("key", "1")   # note that the key used for incr/decr must be a string.
    mc.incr("key")
    mc.decr("key")

The standard way to use memcache with a database is like this::

    key = derive_key(obj)
    obj = mc.get(key)
    if not obj:
        obj = backend_api.get(...)
        mc.set(key, obj)

    # we now have obj, and future passes through this code
    # will use the object from the cache.

Detailed Documentation
======================

More detailed documentation is available in the L{Client} class.

There's no need to use external modules, with just one line you can have the file name and relative path. If you are using modules and need to apply a path relative to the script directory, the relative path is enough.

$0 =~ m/(.+)[\/\\](.+)$/;
print "full path: $1, file name: $2\n";

I could not change the code, so I needed command line for testing purpose and figured this could help someone:

Application specific caches are stored in ~/Library/Caches/<bundle-identifier-of-your-app>, so simply remove as below and re-open your application

rm -rf ~/Library/Caches/com.mycompany.appname/

EDIT: If all your keys are strings, then before continuing to read this answer, please see Jack O'Connor's significantly simpler (and faster) solution (which also works for hashing nested dictionaries).

Although an answer has been accepted, the title of the question is "Hashing a python dictionary", and the answer is incomplete as regards that title. (As regards the body of the question, the answer is complete.)

Nested Dictionaries

If one searches Stack Overflow for how to hash a dictionary, one might stumble upon this aptly titled question, and leave unsatisfied if one is attempting to hash multiply nested dictionaries. The answer above won't work in this case, and you'll have to implement some sort of recursive mechanism to retrieve the hash.

Here is one such mechanism:

import copy

def make_hash(o):

  """
  Makes a hash from a dictionary, list, tuple or set to any level, that contains
  only other hashable types (including any lists, tuples, sets, and
  dictionaries).
  """

  if isinstance(o, (set, tuple, list)):

    return tuple([make_hash(e) for e in o])    

  elif not isinstance(o, dict):

    return hash(o)

  new_o = copy.deepcopy(o)
  for k, v in new_o.items():
    new_o[k] = make_hash(v)

  return hash(tuple(frozenset(sorted(new_o.items()))))

Bonus: Hashing Objects and Classes

The hash() function works great when you hash classes or instances. However, here is one issue I found with hash, as regards objects:

class Foo(object): pass
foo = Foo()
print (hash(foo)) # 1209812346789
foo.a = 1
print (hash(foo)) # 1209812346789

The hash is the same, even after I've altered foo. This is because the identity of foo hasn't changed, so the hash is the same. If you want foo to hash differently depending on its current definition, the solution is to hash off whatever is actually changing. In this case, the __dict__ attribute:

class Foo(object): pass
foo = Foo()
print (make_hash(foo.__dict__)) # 1209812346789
foo.a = 1
print (make_hash(foo.__dict__)) # -78956430974785

Alas, when you attempt to do the same thing with the class itself:

print (make_hash(Foo.__dict__)) # TypeError: unhashable type: 'dict_proxy'

The class __dict__ property is not a normal dictionary:

print (type(Foo.__dict__)) # type <'dict_proxy'>

Here is a similar mechanism as previous that will handle classes appropriately:

import copy

DictProxyType = type(object.__dict__)

def make_hash(o):

  """
  Makes a hash from a dictionary, list, tuple or set to any level, that 
  contains only other hashable types (including any lists, tuples, sets, and
  dictionaries). In the case where other kinds of objects (like classes) need 
  to be hashed, pass in a collection of object attributes that are pertinent. 
  For example, a class can be hashed in this fashion:

    make_hash([cls.__dict__, cls.__name__])

  A function can be hashed like so:

    make_hash([fn.__dict__, fn.__code__])
  """

  if type(o) == DictProxyType:
    o2 = {}
    for k, v in o.items():
      if not k.startswith("__"):
        o2[k] = v
    o = o2  

  if isinstance(o, (set, tuple, list)):

    return tuple([make_hash(e) for e in o])    

  elif not isinstance(o, dict):

    return hash(o)

  new_o = copy.deepcopy(o)
  for k, v in new_o.items():
    new_o[k] = make_hash(v)

  return hash(tuple(frozenset(sorted(new_o.items()))))

You can use this to return a hash tuple of however many elements you'd like:

# -7666086133114527897
print (make_hash(func.__code__))

# (-7666086133114527897, 3527539)
print (make_hash([func.__code__, func.__dict__]))

# (-7666086133114527897, 3527539, -509551383349783210)
print (make_hash([func.__code__, func.__dict__, func.__name__]))

NOTE: all of the above code assumes Python 3.x. Did not test in earlier versions, although I assume make_hash() will work in, say, 2.7.2. As far as making the examples work, I do know that

func.__code__ 

should be replaced with

func.func_code

You need turn on the POP mail and IMAP mail feature in setting of the email you are using to send mail. Good luck!

As an extension to Ignacio Vazquez-Abrams' answer

>>> u'a?ä'.encode('ascii', 'ignore')
'a'

It is sometimes desirable to remove accents from characters and print the base form. This can be accomplished with

>>> import unicodedata
>>> unicodedata.normalize('NFKD', u'a?ä').encode('ascii', 'ignore')
'aa'

You may also want to translate other characters (such as punctuation) to their nearest equivalents, for instance the RIGHT SINGLE QUOTATION MARK unicode character does not get converted to an ascii APOSTROPHE when encoding.

>>> print u'\u2019'
’
>>> unicodedata.name(u'\u2019')
'RIGHT SINGLE QUOTATION MARK'
>>> u'\u2019'.encode('ascii', 'ignore')
''
# Note we get an empty string back
>>> u'\u2019'.replace(u'\u2019', u'\'').encode('ascii', 'ignore')
"'"

Although there are more efficient ways to accomplish this. See this question for more details Where is Python's "best ASCII for this Unicode" database?

I had the same problem, only need to show shortdate (without the time), moreover it was needed to have multi-language settings, so depends of the language, show dd-mm-yyyy or mm-dd-yyyy.

Finally using DataFormatString="{0:d}, all works fine and show only the date with culture format.

You can try something like

SELECT  e.EntityId, 
        e.EntityName, 
        CASE 
            WHEN ep.EntityId IS NULL THEN 'False' 
            ELSE 'TRUE' 
        END AS HasProfile 
FROM    Entities e LEFT JOIN 
        EntityProfiles ep ON e.EntityID = ep.EntityID

Or

SELECT e.EntityId, 
        e.EntityName, 
        CASE 
            WHEN e.EntityProfile IS NULL THEN 'False' 
            ELSE 'TRUE' 
        END AS HasProfile 

FROM    Entities e

One of the benefit of using the resource file is accessing the resources by names, so the image can change, the image name can change, as long as the resource is kept up to date correct image will show up.

Here is a cleaner approach to accomplish this: Assuming Resources.resx is in 'UI.Images' namespace, add the namespace reference in your xaml like this:

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:UI="clr-namespace:UI.Images" 

Set your Image source like this:

<Image Source={Binding {x:Static UI:Resources.Search}} /> where 'Search' is name of the resource.

If you're using GNU find,

find . -mtime 1 -exec cp -t ~/test/ {} +

This works as well as piping the output into xargs while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...).

  n = ThisWorkbook.Worksheets(1).Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count

More information would be useful.

But the simplest form:

#include <iostream>
#include <sstream>
#include <fstream>
#include <string>

int main()
{
    std::ifstream  data("plop.csv");

    std::string line;
    while(std::getline(data,line))
    {
        std::stringstream  lineStream(line);
        std::string        cell;
        while(std::getline(lineStream,cell,','))
        {
            // You have a cell!!!!
        }
    }
 }

There is a new polyfill for translating touch events to drag-and-drop, such that HTML5 Drag And Drop is utilizable on mobile.

The polyfill was introduced by Bernardo Castilho on this post.

Here's a demo from that post.

The post also presents several considerations of the folyfill design.

You could add a compact method to Hash like this

class Hash
  def compact
    delete_if { |k, v| v.nil? }
  end
end

or for a version that supports recursion

class Hash
  def compact(opts={})
    inject({}) do |new_hash, (k,v)|
      if !v.nil?
        new_hash[k] = opts[:recurse] && v.class == Hash ? v.compact(opts) : v
      end
      new_hash
    end
  end
end

You can use this, but remember that your query gives 1 result, multiple results will throw the exception.

declare @ModelID uniqueidentifer
Set @ModelID = (select Top(1) modelid from models where areaid = 'South Coast')

Another way:

Select Top(1)@ModelID = modelid from models where areaid = 'South Coast'

As a rule of thumb:

• private: class scope.
• default (or package-private): package scope.
• protected: package scope + child (like package, but we can subclass it from different packages). The protected modifier always keeps the "parent-child" relationship.
• public: everywhere.

As a result, if we divide access right into three rights:

• (D)irect (invoke from a method inside the same class, or via "this" syntax).
• (R)eference (invoke a method using a reference to the class, or via "dot" syntax).
• (I)nheritance (via subclassing).

then we have this simple table:

+—-———————————————+————————————+———————————+
|                 |    Same    | Different |
|                 |   Package  | Packages  |
+—————————————————+————————————+———————————+
| private         |   D        |           |
+—————————————————+————————————+———————————+
| package-private |            |           |
| (no modifier)   |   D R I    |           |
+—————————————————+————————————+———————————+
| protected       |   D R I    |       I   |
+—————————————————+————————————+———————————+
| public          |   D R I    |    R  I   |
+—————————————————+————————————+———————————+

Generic Object Oriented Solution

For people like me that use frameworks like angular that don't allow manipulating DOM directly, I created a function that takes a string and returns an array of url/plainText objects that can be used to create any UI representation that you want.

URL regex

For URL matching I used (slightly adapted) h0mayun regex: /(?:(?:https?:\/\/)|(?:www\.))[^\s]+/g

My function also drops punctuation characters from the end of a URL like . and , that I believe more often will be actual punctuation than a legit URL ending (but it could be! This is not rigorous science as other answers explain well) For that I apply the following regex onto matched URLs /^(.+?)([.,?!'"]*)$/.

Typescript code

    export function urlMatcherInText(inputString: string): UrlMatcherResult[] {
        if (! inputString) return [];

        const results: UrlMatcherResult[] = [];

        function addText(text: string) {
            if (! text) return;

            const result = new UrlMatcherResult();
            result.type = 'text';
            result.value = text;
            results.push(result);
        }

        function addUrl(url: string) {
            if (! url) return;

            const result = new UrlMatcherResult();
            result.type = 'url';
            result.value = url;
            results.push(result);
        }

        const findUrlRegex = /(?:(?:https?:\/\/)|(?:www\.))[^\s]+/g;
        const cleanUrlRegex = /^(.+?)([.,?!'"]*)$/;

        let match: RegExpExecArray;
        let indexOfStartOfString = 0;

        do {
            match = findUrlRegex.exec(inputString);

            if (match) {
                const text = inputString.substr(indexOfStartOfString, match.index - indexOfStartOfString);
                addText(text);

                var dirtyUrl = match[0];
                var urlDirtyMatch = cleanUrlRegex.exec(dirtyUrl);
                addUrl(urlDirtyMatch[1]);
                addText(urlDirtyMatch[2]);

                indexOfStartOfString = match.index + dirtyUrl.length;
            }
        }
        while (match);

        const remainingText = inputString.substr(indexOfStartOfString, inputString.length - indexOfStartOfString);
        addText(remainingText);

        return results;
    }

    export class UrlMatcherResult {
        public type: 'url' | 'text'
        public value: string
    }

In Windows, like this:

-Djava.library.path="C:/MyLibPath;%PATH%"

%PATH% is your old -Djava.library.path

form.reset() is a DOM element method (not one on the jQuery object), so you need:

$("#client.frm")[0].reset();
//faster version:
$("#client")[0].reset();

Or without jQuery:

document.getElementById("client").reset();

For inside some directory, this will be use full as it copy all contents from "folder1" to new directory "folder2" inside some directory.

$(pwd) will get path for current directory.

Notice the dot (.) after folder1 to get all contents inside folder1

cp -r $(pwd)/folder1/. $(pwd)/folder2

Starting with HTML5, <input type="date" /> will do just fine.

I just discovered this issue. I was able to get around it by using indirection. In each module define a function, lets call it indirect:

function indirect(js) { return eval(js); }

With that function in each module, you can then execute any code in the context of it.

E.g. if you had this import in your module:

import { imported_fn } from "./import.js";

You could then get the results of calling imported_fn from the console by doing this:

indirect("imported_fn()");

Using eval was my first thought, but it doesn't work. My hypothesis is that calling eval from the console remains in the context of console, and we need to execute in the context of the module.

If you want insert into specify column:

INSERT INTO table (time)
(SELECT time FROM 
    dblink('dbname=dbtest', 'SELECT time FROM tblB') AS t(time integer) 
    WHERE time > 1000
);

In your first example, you are making a blank array, same as doing var x = []. The 2nd example makes an array of size 3 (with all elements undefined). The 3rd and 4th examples are the same, they both make arrays with those elements.

Be careful when using new Array().

var x = new Array(10); // array of size 10, all elements undefined
var y = new Array(10, 5); // array of size 2: [10, 5]

The preferred way is using the [] syntax.

var x = []; // array of size 0
var y = [10] // array of size 1: [1]

var z = []; // array of size 0
z[2] = 12;  // z is now size 3: [undefined, undefined, 12]

In the mixins of the Bootstrap sources Sass files, remove all $border references (not in the outline variant).

@mixin button-variant($color, $background, $border){ 
$active-background: darken($background, 10%);
//$active-border: darken($border, 12%);    
  color: $color;
  background-color: $background;
  //border-color: $border;
  @include box-shadow($btn-box-shadow);
  [...]
}

Or simply code you own _customButton.scss mixin.

There are four ways I've found to put a newline into the minibuffer.

1. C-o

2. C-q C-j

3. C-q 12 (12 is the octal value of newline)

4. C-x o to the main window, kill a newline with C-k, then C-x o back to the minibuffer, yank it with C-y

If you are receiving preview of data in the excel source. But while executing the data flow task you receive Acquire connection error. Then move the file to local system and change the file path in excel connection manager and try executing again.

Looks like the type is boolean and therefore can never be null and should be false by default.

One way would be created a JsonObject and iterating through the parameters. For example

JsonObject jobj = new Gson().fromJson(jsonString, JsonObject.class);

Then you can extract bean values like:

String fieldValue = jobj.get(fieldName).getAsString();
boolean fieldValue = jobj.get(fieldName).getAsBoolean();
int fieldValue = jobj.get(fieldName).getAsInt();

Hope this helps.

print("\n".join(sys.path))

(The outer parentheses are included for Python 3 compatibility and are usually omitted in Python 2.)

There are 2 steps to resolve this:

1. Add UseAccessibleHeader="true" to Gridview tag:

   <asp:GridView ID="MyGridView" runat="server" UseAccessibleHeader="true">
   

2. Add the following Code to the PreRender event:

Protected Sub MyGridView_PreRender(sender As Object, e As EventArgs) Handles MyGridView.PreRender
    Try
        MyGridView.HeaderRow.TableSection = TableRowSection.TableHeader
    Catch ex As Exception
    End Try
End Sub

Note setting Header Row in DataBound() works only when the object is databound, any other postback that doesn't databind the gridview will result in the gridview header row style reverting to a standard row again. PreRender works everytime, just make sure you have an error catch for when the gridview is empty.

Set the background color of the src to none and allow transparencey.

[WITHIN SCR PAGE STYLE]
<style type="text/css">
    body
    {
        background:none transparent;
    }
</style>

[IFRAME]
<iframe src="#" allowtransparency="true">Error, iFrame failed to load.</iframe>

NOTE: I code my CSS a little different to how everyone else does.

Put the loops in a subroutine and call return

on anchor tag use href and not onclick

<a href="#target1">asdf<a>

And div:

<div id="target1">some content</div>

BufferedReader br = null;
try {
        String fpath = Environment.getExternalStorageDirectory() + <your file name>;
        try {
            br = new BufferedReader(new FileReader(fpath));
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        }
        String line = "";
        while ((line = br.readLine()) != null) {
         //Do something here 
        }

wget uses environment variables somthing like this at command line can work:

export http_proxy=http://your_ip_proxy:port/
export https_proxy=$http_proxy
export ftp_proxy=$http_proxy
export dns_proxy=$http_proxy
export rsync_proxy=$http_proxy
export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"

Keeping the code simple is always my advice:

If IsNull(Me.Id) = True Then
  DoCmd.GoToRecord , , acNext
Else
  DoCmd.GoToRecord , , acLast
End If

You can get this info from the ResultSet metadata. See ResultSetMetaData

e.g.

 ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
 ResultSetMetaData rsmd = rs.getMetaData();
 String name = rsmd.getColumnName(1);

and you can get the column name from there. If you do

select x as y from table

then rsmd.getColumnLabel() will get you the retrieved label name too.

Here is a working example :

document.cookie = "testCookie=cookieval; domain=." + 
location.hostname.split('.').reverse()[1] + "." + 
location.hostname.split('.').reverse()[0] + "; path=/"

This is a generic solution that takes the root domain from the location object and sets the cookie. The reversing is because you don't know how many subdomains you have if any.

In WPF an image is typically loaded from a Stream or an Uri.

BitmapImage supports both and an Uri can even be passed as constructor argument:

var uri = new Uri("http://...");
var bitmap = new BitmapImage(uri);

If the image file is located in a local folder, you would have to use a file:// Uri. You could create such a Uri from a path like this:

var path = Path.Combine(Environment.CurrentDirectory, "Bilder", "sas.png");
var uri = new Uri(path);

If the image file is an assembly resource, the Uri must follow the the Pack Uri scheme:

var uri = new Uri("pack://application:,,,/Bilder/sas.png");

In this case the Visual Studio Build Action for sas.png would have to be Resource.

Once you have created a BitmapImage and also have an Image control like in this XAML

<Image Name="image1" />

you would simply assign the BitmapImage to the Source property of that Image control:

image1.Source = bitmap;

            }
        }

When you use the input function it automatically turns it into a string. You need to go:

vote = int(input('Enter the name of the player you wish to vote for'))

which turns the input into a int type value

Discovered one more thing to check - look in Task manager - if other users are connected to this box, even if they are 'disconnected' you have to actually sign them out to get the service to finally delete.

4. window.location.replace("http://www.example.com/index.php");

Edited: Kindly note that
whereBetween('date',$start_date,$end_date)

No, it needs three operands. That's why they're called ternary operators.

However, for what you have as your example, you can do this:

if(condition) x = true;

Although it's safer to have braces if you need to add more than one statement in the future:

if(condition) { x = true; }

Edit: Now that you mention the actual code in which your question applies to:

if(!defaults.slideshowWidth)
    { defaults.slideshowWidth = obj.find('img').width()+'px'; }

try the following code

select * from TableA A 
inner join TableB B on A.Column=B.Column 
inner join TableC C on A.Column=C.Column

In Ubuntu:

First You have to check that is the Docker Database port is Available in your system by following command -

sudo iptables -L -n

Sample OUTPUT:

Chain DOCKER (1 references)
target     prot opt source               destination         
ACCEPT     tcp  --  0.0.0.0/0            172.17.0.2           tcp dpt:3306
ACCEPT     tcp  --  0.0.0.0/0            172.17.0.3           tcp dpt:80
ACCEPT     tcp  --  0.0.0.0/0            172.17.0.3           tcp dpt:22

Here 3306 is used as Docker Database Port on 172.17.0.2 IP, If this port is not available Run the following command -

sudo iptables -A INPUT -p tcp --dport 3306 -j ACCEPT

Now, You can easily access the Docker Database from your local system by following configuration

  host: 172.17.0.2 
  adapter: mysql
  database: DATABASE_NAME
  port: 3307
  username: DATABASE_USER
  password: DATABASE_PASSWORD
  encoding: utf8

In CentOS:

First You have to check that is the Docker Database port is Available in your firewall by following command -

sudo firewall-cmd --list-all

Sample OUTPUT:

  target: default
  icmp-block-inversion: no
  interfaces: eno79841677
  sources: 
  services: dhcpv6-client ssh
  **ports: 3307/tcp**
  protocols: 
  masquerade: no
  forward-ports: 
  sourceports: 
  icmp-blocks: 
  rich rules:

Here 3307 is used as Docker Database Port on 172.17.0.2 IP, If this port is not available Run the following command -

sudo firewall-cmd --zone=public --add-port=3307/tcp

In server, You can add the port permanently

sudo firewall-cmd --permanent --add-port=3307/tcp
sudo firewall-cmd --reload

Now, You can easily access the Docker Database from your local system by the above configuration.

You've basically answered anything and everything already, so I'm no sure what the point is here?

FWIW I would use an httphandler - there seems no point in invoking a page lifecycle and having to deal with clipping off the bits of viewstate and session and what have you which don't make sense for an XML doc. It's like buying a car and stripping it for parts to make your motorbike.

And content-type is all important, it's how the requester knows what to do with the response.

concurrent.futures.as_completed

https://docs.python.org/3.7/library/concurrent.futures.html#concurrent.futures.as_completed

The following solution:

• returns to the main thread immediately when an exception is called
• requires no extra user defined classes because it does not need:
  • an explicit Queue
  • to add an except else around your work thread

Source:

#!/usr/bin/env python3

import concurrent.futures
import time

def func_that_raises(do_raise):
    for i in range(3):
        print(i)
        time.sleep(0.1)
    if do_raise:
        raise Exception()
    for i in range(3):
        print(i)
        time.sleep(0.1)

with concurrent.futures.ThreadPoolExecutor(max_workers=2) as executor:
    futures = []
    futures.append(executor.submit(func_that_raises, False))
    futures.append(executor.submit(func_that_raises, True))
    for future in concurrent.futures.as_completed(futures):
        print(repr(future.exception()))

Possible output:

0
0
1
1
2
2
0
Exception()
1
2
None

It is unfortunately not possible to kill futures to cancel the others as one fails:

• concurrent.features; Python: concurrent.futures How to make it cancelable?
• threading: Is there any way to kill a Thread?
• C pthreads: Kill Thread in Pthread Library

If you do something like:

for future in concurrent.futures.as_completed(futures):
    if future.exception() is not None:
        raise future.exception()

then the with catches it, and waits for the second thread to finish before continuing. The following behaves similarly:

for future in concurrent.futures.as_completed(futures):
    future.result()

since future.result() re-raises the exception if one occurred.

If you want to quit the entire Python process, you might get away with os._exit(0), but this likely means you need a refactor.

Custom class with perfect exception semantics

I ended up coding the perfect interface for myself at: The right way to limit maximum number of threads running at once? section "Queue example with error handling". That class aims to be both convenient, and give you total control over submission and result / error handling.

Tested on Python 3.6.7, Ubuntu 18.04.

This might sound like a really basic "DUH" answer, but make sure that the column you're using to Lookup from on the merging file is actually full of unique values!

I noticed earlier today that PowerQuery won't throw you an error (like in PowerPivot) and will happily allow you to run a Many-Many merge. This will result in multiple rows being produced for each record that matches with a non-unique value.

In Python 3, dict.values() (along with dict.keys() and dict.items()) returns a view, rather than a list. See the documentation here. You therefore need to wrap your call to dict.values() in a call to list like so:

v = list(d.values())
{names[i]:v[i] for i in range(len(names))}

Here is a small contribution :

array=(word "two words" words)  
search_string="two"  
match=$(echo "${array[@]:0}" | grep -o $search_string)  
[[ ! -z $match ]] && echo "found !"  

Note: this way doesn't distinguish the case "two words" but this is not required in the question.

For me it is an entirely different story.
Since this page has a good search engine ranking, I should add my case and the solution here too.

I built jquery myself with webpack picking only the modules I use. The ajax is always failed with "No Transport" message as the only clue.

After a long debugging, the problem turns out to be XMLHttpRequest is pluggable in jquery and it not include by default.

You have to explicitly include jquery/src/ajax/xhr file in order to make the ajax working in browsers.

The way without re-inserting all entries into the new map should be the fastest it won't because HashMap.clone internally performs rehash as well.

Map<String, Column> newColumnMap = originalColumnMap.clone();
newColumnMap.replaceAll((s, c) -> new Column(c));

public class Network {

Context context;

public Network(Context context){
    this.context = context;
}

public boolean isOnline() {
    ConnectivityManager cm =
            (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    return activeNetwork != null &&
                          activeNetwork.isConnectedOrConnecting();
}

}

You can generate a XmlHttpRequest and request the page,and then use getResponseText() to get the content.

I use the following code to create PDF

protected void CreatePDF(Stream stream)
        {
            using (var document = new Document(PageSize.A4, 40, 40, 40, 30))
            {
                var writer = PdfWriter.GetInstance(document, stream);

                tagProcessorFactory.AddProcessor(
                    new TableProcessor(),
                    new string[] { HTML.Tag.TABLE }
                );

                fontProvider.Register(HttpContext.Current.Server.MapPath("~/Content/Fonts/GothamRounded-Medium.ttf"), "Gotham Rounded Medium");
                CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);

                var htmlPipelineContext = new HtmlPipelineContext(cssAppliers);
                htmlPipelineContext.SetTagFactory(tagProcessorFactory);

                var pdfWriterPipeline = new PdfWriterPipeline(document, writer);
                var htmlPipeline = new HtmlPipeline(htmlPipelineContext, pdfWriterPipeline);

                // get an ICssResolver and add the custom CSS
                var cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(true);
                cssResolver.AddCss(CSSSource, "utf-8", true);
                var cssResolverPipeline = new CssResolverPipeline(
                    cssResolver, htmlPipeline
                );

                var worker = new XMLWorker(cssResolverPipeline, true);
                var parser = new XMLParser(worker);
                using (var stringReader = new StringReader(HTMLSource))
                {
                    parser.Parse(stringReader);
                    document.Close();
                    HttpContext.Current.Response.ContentType = "application /pdf";
                    if (base.View)
                        HttpContext.Current.Response.AddHeader("content-disposition", "inline;filename=\"" + OutputFileName + ".pdf\"");

Heap is just an area where memory is allocated or deallocated without any order. This happens when one creates an object using the new operator or something similar. This is opposed to stack where memory is deallocated on the first in last out basis.

Try using the net use command in your script to map the share first, because you can provide it credentials. Then, your copy command should use those credentials.

net use \\<network-location>\<some-share> password /USER:username

Don't leave a trailing \ at the end of the

With a = subprocess.Popen("cdrecord --help",stdout = subprocess.PIPE) , you need to either use a list or use shell=True;

Either of these will work. The former is preferable.

a = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE)

a = subprocess.Popen('cdrecord --help', shell=True, stdout=subprocess.PIPE)

Also, instead of using Popen.stdout.read/Popen.stderr.read, you should use .communicate() (refer to the subprocess documentation for why).

proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()

Gradle 4.9+

gradle run --args='arg1 arg2'

This assumes your build.gradle is configured with the Application plugin. Your build.gradle should look similar to this:

plugins {
  // Implicitly applies Java plugin
  id: 'application'
}

application {
  // URI of your main class/application's entry point (required)
  mainClassName = 'org.gradle.sample.Main'
}

Pre-Gradle 4.9

Include the following in your build.gradle:

run {
    if (project.hasProperty("appArgs")) {
        args Eval.me(appArgs)
    }
}

Then to run: gradle run -PappArgs="['arg1', 'args2']"

In Python monkeypatching generally works by overwriting a class or function's signature with your own. Below is an example from the Zope Wiki:

from SomeOtherProduct.SomeModule import SomeClass
def speak(self):
   return "ook ook eee eee eee!"
SomeClass.speak = speak

This code will overwrite/create a method called peak in the class. In Jeff Atwood's recent post on monkey patching, he showed an example in C# 3.0 which is the current language I use for work.

I would use SQL Server Full Text Indexing, which will allow you to do searches and return things that not only contain the word but also may have a misspelling.

Most of the references on the web about this issue point out to the fact that you cannot download files via ajax call 'out of the box'. I have seen (hackish) solutions that involve iframes and also solutions like @dcodesmith's that work and are perfectly viable.

Here's another solution I found that works in Angular and is very straighforward.

In the view, wrap the csv download button with <a> tag the following way :

<a target="_self" ng-href="{{csv_link}}">
  <button>download csv</button>
</a>

(Notice the target="_self there, it's crucial to disable Angular's routing inside the ng-app more about it here)

Inside youre controller you can define csv_link the following way :

$scope.csv_link = '/orders' + $window.location.search;

(the $window.location.search is optional and onlt if you want to pass additionaly search query to your server)

Now everytime you click the button, it should start downloading.

Since this question is still getting a lot of attention, I decided to answer it by copying this answer from Code Review.SE:

You're following the same philosophy as the bubble sort, which is very, very, very slow. Have you tried this?:

• Sort your unordered array with quicksort. Quicksort is much faster than bubble sort (I know, you are not sorting, but the algorithm you follow is almost the same as bubble sort to traverse the array).

• Then start removing duplicates (repeated values will be next to each other). In a for loop you could have two indices: source and destination. (On each loop you copy source to destination unless they are the same, and increment both by 1). Every time you find a duplicate you increment source (and don't perform the copy). @morgano

If the web service being invoked uses windows integrated security, creating a NetworkCredential from the current WindowsIdentity should be sufficient to allow the web service to use the current users windows login. However, if the web service uses a different security model, there isn't any way to extract a users password from the current identity ... that in and of itself would be insecure, allowing you, the developer, to steal your users passwords. You will likely need to provide some way for your user to provide their password, and keep it in some secure cache if you don't want them to have to repeatedly provide it.

Edit: To get the credentials for the current identity, use the following:

Uri uri = new Uri("http://tempuri.org/");
ICredentials credentials = CredentialCache.DefaultCredentials;
NetworkCredential credential = credentials.GetCredential(uri, "Basic");

 moment(dateString, 'YYYY-MM-DD', true).isValid() ||
 moment(dateString, 'YYYY-M-DD', true).isValid() ||
 moment(dateString, 'YYYY-MM-D', true).isValid();

Use pandas!

import datetime
# BDay is business day, not birthday...
from pandas.tseries.offsets import BDay

today = datetime.datetime.today()
print(today - BDay(4))

Since today is Thursday, Sept 26, that will give you an output of:

datetime.datetime(2013, 9, 20, 14, 8, 4, 89761)

I would use a for loop to iterate over the lines in the text file:

for line in my_text:
    outputfile.writelines(data_parser(line, reps))

If you want to read the file line-by-line instead of loading the whole thing at the start of the script you could do something like this:

inputfile = open('test.dat')
outputfile = open('test.csv', 'w')

# sample text string, just for demonstration to let you know how the data looks like
# my_text = '"2012-06-23 03:09:13.23",4323584,-1.911224,-0.4657288,-0.1166382,-0.24823,0.256485,"NAN",-0.3489428,-0.130449,-0.2440527,-0.2942413,0.04944348,0.4337797,-1.105218,-1.201882,-0.5962594,-0.586636'

# dictionary definition 0-, 1- etc. are there to parse the date block delimited with dashes, and make sure the negative numbers are not effected
reps = {'"NAN"':'NAN', '"':'', '0-':'0,','1-':'1,','2-':'2,','3-':'3,','4-':'4,','5-':'5,','6-':'6,','7-':'7,','8-':'8,','9-':'9,', ' ':',', ':':',' }

for i in range(4): inputfile.next() # skip first four lines
for line in inputfile:
    outputfile.writelines(data_parser(line, reps))

inputfile.close()
outputfile.close()

Finally found the simplest way:

<button (click)="toggle($event)" class="someclass" id="btn1"></button>
<button (click)="toggle($event)" class="someclass" id="btn2"></button>

toggle(event) {
   console.log(event.target.id); 
}

Demo Here

var e = jQuery.Event("keypress");
e.which = 13; //choose the one you want
e.keyCode = 13;
$("#theInputToTest").trigger(e);

What i did was i commented out the

props.put("mail.smtp.starttls.enable","true"); 

Because apparently for G-mail you did not need it. Then if you haven't already done this you need to create an app password in G-mail for your program. I did that and it worked perfectly. Here this link will show you how: https://support.google.com/accounts/answer/185833.

Employer employer = context.Employers.First(x => x.EmployerId == 1);

context.Customers.DeleteObject(employer);
context.SaveChanges();

I'm going to weigh in on this (Angular 7 Solution)

Working with Subclipse on Eclipse Indigo Service Release 2

I had commited folders with temporary files and logs lying under /src to the SVN repository. And after realizing it, I found myself in the same situation with a grayed out "svn:ignore"

I found following solution:

1. I deleted the folder from my Project Source

2. Team -> Commit... withouth the folder

3. Recreated the folder back into the project tree

Now I was able to use "Team -> Add to svn:ignore..."

You can use this

function removeEntity(object) {
    var scene = document.querySelectorAll("scene");                               //clear the objects from the scene
    for (var i = 0; i < scene.length; i++) {                                    //loop through to get all object in the scene
    var scene =document.getElementById("scene");                                  
    scene.removeChild(scene.childNodes[0]);                                        //remove all specified objects
  }   

Very interesting thread, I especially liked idea to just factor subselection again. I had the similar problem before and I just converted to character and then back to factor.

   df <- data.frame(letters=letters[1:5],numbers=seq(1:5))
   levels(df$letters)
   ## [1] "a" "b" "c" "d" "e"
   subdf <- df[df$numbers <= 3]
   subdf$letters<-factor(as.character(subdf$letters))

Starting

start-dfs.sh (starts the namenode and the datanode)
start-mapred.sh (starts the jobtracker and the tasktracker)

Stopping

stop-dfs.sh
stop-mapred.sh

If you have a collection of objects that you load using stored procedure you can also use LoadFromCollection.

using (ExcelPackage package = new ExcelPackage(file))
{
    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("test");

    worksheet.Cells["A1"].LoadFromCollection(myColl, true, OfficeOpenXml.Table.TableStyles.Medium1);

    package.Save();
}

Don't update the primary key. It could cause a lot of problems for you keeping your data intact, if you have any other tables referencing it.

Ideally, if you want a unique field that is updateable, create a new field.

ClickOnce apps are designed so that the end user downloads a "downloader" - the ClickOnce app, then when ya run it, it downloads and installs in %LocalAppData%\Apps\2.0..... and then it's random folder names for every OS install you do. Backing up is pointless and so is trying to move the program. The point of ClickOnce is 2-Fold: 1. AutoUpdating of the program 2. The end user has no installer and also can't move the app or it breaks

The %LocalAppData%\Apps\2.0..... folder is the program AND %LocalAppData%\GitHub is the settings folder.

I'm not going to cover how to circumvent this - only stating the above. :P

The best 'tip' I can say legitimately is: You 'can' in some cases move the final folder that all the files are in and use a symlink back, if you are low on space. But, not all apps will work and essentially will delete the symlink once you they run. Then they might reinstall or simply just remove the link. Keep in mind also, other apps may be using that same final folder as well, so move the folder will affect those too.

Another option would be to add engine='python' to the command pandas.read_csv(filename, sep='\t', engine='python')

Simply using below code in Kotlin works for me

WebView(applicationContext).clearCache(true)

In Oracle 11g, if you want to search any text in whole database or procedure below mentioned query can be used:

select * from user_source WHERE UPPER(text) LIKE '%YOUR SAGE%'

calculate distance in Mysql

 SELECT (6371 * acos(cos(radians(lat2)) * cos(radians(lat1) ) * cos(radians(long1) -radians(long2)) + sin(radians(lat2)) * sin(radians(lat1)))) AS distance

thus distance value will be calculated and anyone can apply as required.

If I want something like sed, then I usually just call sed itself using the sh library.

from sh import sed

sed(['-i', 's/^# deb/deb/', '/etc/apt/sources.list'])

Sure, there are downsides. Like maybe the locally installed version of sed isn't the same as the one you tested with. In my cases, this kind of thing can be easily handled at another layer (like by examining the target environment beforehand, or deploying in a docker image with a known version of sed).

PHP can be frustrating for this reason. The answers above using global did not work for me, and it took me awhile to figure out the proper use of use.

This is correct:

$functionName = function($stuff) use ($globalVar) {
 //do stuff
}
$output = $functionName($stuff);
$otherOutput = $functionName($otherStuff);

This is incorrect:

function functionName($stuff) use ($globalVar) {
 //do stuff
}
$output = functionName($stuff);
$otherOutput = functionName($otherStuff);

Using your specific example:

    $data = 'My data';

    $menugen = function() use ($data) {
        echo "[" . $data . "]";
    }

    $menugen();

You should try using nohup and running it in the background:

nohup sleep 3600 &

Old thread, but maybe my answer will help someone. I resolved by executing the query first, then setting an errors variable, then checking if that errors variable array is empty. see simplified example:

$field1 = 'foo';
$field2 = 'bar';

$insert_QUERY = $db->prepare("INSERT INTO table bogus(field1, field2) VALUES (:field1, :field2)");
$insert_QUERY->bindParam(':field1', $field1);
$insert_QUERY->bindParam(':field2', $field2);

$insert_QUERY->execute();

$databaseErrors = $insert_QUERY->errorInfo();

if( !empty($databaseErrors) ){  
    $errorInfo = print_r($databaseErrors, true); # true flag returns val rather than print
    $errorLogMsg = "error info: $errorInfo"; # do what you wish with this var, write to log file etc...         

/* 
 $errorLogMsg will return something like: 
 error info:  
 Array(
  [0] => 42000
  [1] => 1064
  [2] => You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'table bogus(field1, field2) VALUES                                                  ('bar', NULL)' at line 1

The new urllib3 library has a nice documentation here
In order to get your desired result you shuld follow that:

Import urllib3
from bs4 import BeautifulSoup

url = 'http://www.thefamouspeople.com/singers.php'

http = urllib3.PoolManager()
response = http.request('GET', url)
soup = BeautifulSoup(response.data.decode('utf-8'))

The "decode utf-8" part is optional. It worked without it when i tried, but i posted the option anyway.

Using set bg=dark with a white background can produce nearly unreadable text in some syntax highlighting schemes. Instead, you can change the overall colorscheme to something that looks good in your terminal. The colorscheme file should set the background attribute for you appropriately. Also, for more information see:

I assume curl is reading the proxy address from the environment variable http_proxy and that the variable should keep its value. Then in a shell like bash, export http_proxy=''; before a command (or in a shell script) would temporarily change its value.

(See curl's manual for all the variables it looks at, under the ENVIRONMENT heading.)

After a full day of search, I disabled Avast for 10 minutes and Windows Firewall (important) and everything started working!

This was my error:

Mail server connection failed; nested exception is javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target. Failed messages: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target  

Here is how to fix the issue in Avast 19.8.2393 by adding an exclusion to SMTP port 587 (or whichever port your application uses):

1. Open Avast

2. Click on 'Settings'

3. Click on 'Troubleshooting' and then 'Open old settings'

4. Click again on 'Troubleshooting', scroll down to 'Redirect settings' and delete the port that your app uses.

In my case, I just removed 587 from SMTP ports.

Now I am able to use Avast and also have my Windows Firewall switched on (no need to add additional exclusion for the Firewall).

Here are my application.properties e-mail properties:

###### I am using a Google App Password which I generated in my Gmail Security settings ######
spring.mail.host = smtp.gmail.com
spring.mail.port = 587
spring.mail.protocol = smtp

In Asp.Net MVC when you use @Html.AntiForgeryToken() Razor creates a hidden input field with name __RequestVerificationToken to store tokens. If you want to write an AJAX implementation you have to fetch this token yourself and pass it as a parameter to the server so it can be validated.

Step 1: Get the token

var token = $('input[name="`__RequestVerificationToken`"]').val();

Step 2: Pass the token in the AJAX call

function registerStudent() {

var student = {     
    "FirstName": $('#fName').val(),
    "LastName": $('#lName').val(),
    "Email": $('#email').val(),
    "Phone": $('#phone').val(),
};

$.ajax({
    url: '/Student/RegisterStudent',
    type: 'POST',
    data: { 
     __RequestVerificationToken:token,
     student: student,
        },
    dataType: 'JSON',
    contentType:'application/x-www-form-urlencoded; charset=utf-8',
    success: function (response) {
        if (response.result == "Success") {
            alert('Student Registered Succesfully!')

        }
    },
    error: function (x,h,r) {
        alert('Something went wrong')
      }
})
};

Note: The content type should be 'application/x-www-form-urlencoded; charset=utf-8'

I have uploaded the project on Github; you can download and try it.

I would put this in a comment to ghostdog74, except my rep is too low, so here goes.

more +2 file2.txt > temp
This code will actually ignore rows 1 and 2 of the file. OP wants to keep all rows from the first file (to maintain the header row), and then exclude the first row (presumably the same header row) on the second file, so to exclude only the header row OP should use more +1.

type temp file1.txt > out.txt

It is unclear what order results from this code. Is temp appended to file1.txt (as desired), or is file1.txt appended to temp (undesired as the header row would be buried in the middle of the resulting file).

In addition, these operations take a REALLY LONG TIME with large files (e.g. 300MB)

Please Try the following codes :

Import Execute 

Execute("zbx_control.sh")

If your classes are in the same package, you won't need to import. To call a method from class B in class A, you should use classB.methodName(arg)

Swift Answer

This is meant to supplement my Objective-C answer for Swift users, to keep the Objective-C answer from getting too big.

Setup

First, set up the in-app purchase on appstoreconnect.apple.com. Follow the beginning part of my Objective-C answer (steps 1-13, under the App Store Connect header) for instructions on doing that.

It could take a few hours for your product ID to register in App Store Connect, so be patient.

Now that you've set up your in-app purchase information on App Store Connect, we need to add Apple's framework for in-app-purchases, StoreKit, to the app.

Go into your Xcode project, and go to the application manager (blue page-like icon at the top of the left bar where your app's files are). Click on your app under targets on the left (it should be the first option), then go to "Capabilities" at the top. On the list, you should see an option "In-App Purchase". Turn this capability ON, and Xcode will add StoreKit to your project.

Coding

Now, we're going to start coding!

First, make a new swift file that will manage all of your in-app-purchases. I'm going to call it IAPManager.swift.

In this file, we're going to create a new class, called IAPManager that is a SKProductsRequestDelegate and SKPaymentTransactionObserver. At the top, make sure you import Foundation and StoreKit

import Foundation
import StoreKit

public class IAPManager: NSObject, SKProductsRequestDelegate,
                         SKPaymentTransactionObserver {
}

Next, we're going to add a variable to define the identifier for our in-app purchase (you could also use an enum, which would be easier to maintain if you have multiple IAPs).

// This should the ID of the in-app-purchase you made on AppStore Connect.
// if you have multiple IAPs, you'll need to store their identifiers in
// other variables, too (or, preferably in an enum).
let removeAdsID = "com.skiplit.removeAds"

Let's add an initializer for our class next:

// This is the initializer for your IAPManager class
//
// A better, and more scaleable way of doing this
// is to also accept a callback in the initializer, and call
// that callback in places like the paymentQueue function, and
// in all functions in this class, in place of calls to functions
// in RemoveAdsManager (you'll see those calls in the code below).

let productID: String
init(productID: String){
    self.productID = productID
}

Now, we're going to add the required functions for SKProductsRequestDelegate and SKPaymentTransactionObserver to work:

_{We'll add the RemoveAdsManager class later}

// This is called when a SKProductsRequest receives a response
public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse){
    // Let's try to get the first product from the response
    // to the request
    if let product = response.products.first{
        // We were able to get the product! Make a new payment
        // using this product
        let payment = SKPayment(product: product)

        // add the new payment to the queue
        SKPaymentQueue.default().add(self)
        SKPaymentQueue.default().add(payment)
    }
    else{
        // Something went wrong! It is likely that either
        // the user doesn't have internet connection, or
        // your product ID is wrong!
        //
        // Tell the user in requestFailed() by sending an alert,
        // or something of the sort

        RemoveAdsManager.removeAdsFailure()
    }
}

// This is called when the user restores their IAP sucessfully
private func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue){
    // For every transaction in the transaction queue...
    for transaction in queue.transactions{
        // If that transaction was restored
        if transaction.transactionState == .restored{
            // get the producted ID from the transaction
            let productID = transaction.payment.productIdentifier

            // In this case, we have only one IAP, so we don't need to check
            // what IAP it is. However, this is useful if you have multiple IAPs!
            // You'll need to figure out which one was restored
            if(productID.lowercased() == IAPManager.removeAdsID.lowercased()){
                // Restore the user's purchases
                RemoveAdsManager.restoreRemoveAdsSuccess()
            }

            // finish the payment
            SKPaymentQueue.default().finishTransaction(transaction)
        }
    }
}

// This is called when the state of the IAP changes -- from purchasing to purchased, for example.
// This is where the magic happens :)
public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]){
    for transaction in transactions{
        // get the producted ID from the transaction
        let productID = transaction.payment.productIdentifier

        // In this case, we have only one IAP, so we don't need to check
        // what IAP it is.
        // However, if you have multiple IAPs, you'll need to use productID
        // to check what functions you should run here!

        switch transaction.transactionState{
        case .purchasing:
            // if the user is currently purchasing the IAP,
            // we don't need to do anything.
            //
            // You could use this to show the user
            // an activity indicator, or something like that
            break
        case .purchased:
            // the user successfully purchased the IAP!
            RemoveAdsManager.removeAdsSuccess()
            SKPaymentQueue.default().finishTransaction(transaction)
        case .restored:
                // the user restored their IAP!
                IAPTestingHandler.restoreRemoveAdsSuccess()
                SKPaymentQueue.default().finishTransaction(transaction)
        case .failed:
                // The transaction failed!
                RemoveAdsManager.removeAdsFailure()
                // finish the transaction
                SKPaymentQueue.default().finishTransaction(transaction)
        case .deferred:
                // This happens when the IAP needs an external action
                // in order to proceeded, like Ask to Buy
                RemoveAdsManager.removeAdsDeferred()
                break
        }
    }
}

Now let's add some functions that can be used to start a purchase or a restore purchases:

// Call this when you want to begin a purchase
// for the productID you gave to the initializer
public func beginPurchase(){
    // If the user can make payments
    if SKPaymentQueue.canMakePayments(){
        // Create a new request
        let request = SKProductsRequest(productIdentifiers: [productID])
        // Set the request delegate to self, so we receive a response
        request.delegate = self
        // start the request
        request.start()
    }
    else{
        // Otherwise, tell the user that
        // they are not authorized to make payments,
        // due to parental controls, etc
    }
}

// Call this when you want to restore all purchases
// regardless of the productID you gave to the initializer
public func beginRestorePurchases(){
    // restore purchases, and give responses to self
    SKPaymentQueue.default().add(self)
    SKPaymentQueue.default().restoreCompletedTransactions()
}

Next, let's add a new utilities class to manage our IAPs. All of this code could be in one class, but having it multiple makes it a little cleaner. I'm going to make a new class called RemoveAdsManager, and in it, put a few functions

public class RemoveAdsManager{

    class func removeAds()
    class func restoreRemoveAds()

    class func areAdsRemoved() -> Bool

    class func removeAdsSuccess()
    class func restoreRemoveAdsSuccess()
    class func removeAdsDeferred()
    class func removeAdsFailure()
}

The first three functions, removeAds, restoreRemoveAds, and areAdsRemoved, are functions that you'll call to do certain actions. The last four are one that will be called by IAPManager.

Let's add some code to the first two functions, removeAds and restoreRemoveAds:

// Call this when the user wants
// to remove ads, like when they
// press a "remove ads" button
class func removeAds(){
    // Before starting the purchase, you could tell the
    // user that their purchase is happening, maybe with
    // an activity indicator

    let iap = IAPManager(productID: IAPManager.removeAdsID)
    iap.beginPurchase()
}

// Call this when the user wants
// to restore their IAP purchases,
// like when they press a "restore
// purchases" button.
class func restoreRemoveAds(){
    // Before starting the purchase, you could tell the
    // user that the restore action is happening, maybe with
    // an activity indicator

    let iap = IAPManager(productID: IAPManager.removeAdsID)
    iap.beginRestorePurchases()
}

And lastly, let's add some code to the last five functions.

// Call this to check whether or not
// ads are removed. You can use the
// result of this to hide or show
// ads
class func areAdsRemoved() -> Bool{
    // This is the code that is run to check
    // if the user has the IAP.

    return UserDefaults.standard.bool(forKey: "RemoveAdsPurchased")
}

// This will be called by IAPManager
// when the user sucessfully purchases
// the IAP
class func removeAdsSuccess(){
    // This is the code that is run to actually
    // give the IAP to the user!
    //
    // I'm using UserDefaults in this example,
    // but you may want to use Keychain,
    // or some other method, as UserDefaults
    // can be modified by users using their
    // computer, if they know how to, more
    // easily than Keychain

    UserDefaults.standard.set(true, forKey: "RemoveAdsPurchased")
    UserDefaults.standard.synchronize()
}

// This will be called by IAPManager
// when the user sucessfully restores
//  their purchases
class func restoreRemoveAdsSuccess(){
    // Give the user their IAP back! Likely all you'll need to
    // do is call the same function you call when a user
    // sucessfully completes their purchase. In this case, removeAdsSuccess()

    removeAdsSuccess()
}

// This will be called by IAPManager
// when the IAP failed
class func removeAdsFailure(){
    // Send the user a message explaining that the IAP
    // failed for some reason, and to try again later
}

// This will be called by IAPManager
// when the IAP gets deferred.
class func removeAdsDeferred(){
    // Send the user a message explaining that the IAP
    // was deferred, and pending an external action, like
    // Ask to Buy.
}

Putting it all together, we get something like this:

import Foundation
import StoreKit

public class RemoveAdsManager{

    // Call this when the user wants
    // to remove ads, like when they
    // press a "remove ads" button
    class func removeAds(){
        // Before starting the purchase, you could tell the
        // user that their purchase is happening, maybe with
        // an activity indicator

        let iap = IAPManager(productID: IAPManager.removeAdsID)
        iap.beginPurchase()
    }

    // Call this when the user wants
    // to restore their IAP purchases,
    // like when they press a "restore
    // purchases" button.
    class func restoreRemoveAds(){
        // Before starting the purchase, you could tell the
        // user that the restore action is happening, maybe with
        // an activity indicator

        let iap = IAPManager(productID: IAPManager.removeAdsID)
        iap.beginRestorePurchases()
    }

    // Call this to check whether or not
    // ads are removed. You can use the
    // result of this to hide or show
    // ads
    class func areAdsRemoved() -> Bool{
        // This is the code that is run to check
        // if the user has the IAP.

        return UserDefaults.standard.bool(forKey: "RemoveAdsPurchased")
    }

    // This will be called by IAPManager
    // when the user sucessfully purchases
    // the IAP
    class func removeAdsSuccess(){
        // This is the code that is run to actually
        // give the IAP to the user!
        //
        // I'm using UserDefaults in this example,
        // but you may want to use Keychain,
        // or some other method, as UserDefaults
        // can be modified by users using their
        // computer, if they know how to, more
        // easily than Keychain

        UserDefaults.standard.set(true, forKey: "RemoveAdsPurchased")
        UserDefaults.standard.synchronize()
    }

    // This will be called by IAPManager
    // when the user sucessfully restores
    //  their purchases
    class func restoreRemoveAdsSuccess(){
        // Give the user their IAP back! Likely all you'll need to
        // do is call the same function you call when a user
        // sucessfully completes their purchase. In this case, removeAdsSuccess()
        removeAdsSuccess()
    }

    // This will be called by IAPManager
    // when the IAP failed
    class func removeAdsFailure(){
        // Send the user a message explaining that the IAP
        // failed for some reason, and to try again later
    }

    // This will be called by IAPManager
    // when the IAP gets deferred.
    class func removeAdsDeferred(){
        // Send the user a message explaining that the IAP
        // was deferred, and pending an external action, like
        // Ask to Buy.
    }

}

public class IAPManager: NSObject, SKProductsRequestDelegate, SKPaymentTransactionObserver{

    // This should the ID of the in-app-purchase you made on AppStore Connect.
    // if you have multiple IAPs, you'll need to store their identifiers in

                // we don't need to do anything.
                //
                // You could use this to show the user
                // an activity indicator, or something like that
                break
            case .purchased:
                // the user sucessfully purchased the IAP!
                RemoveAdsManager.removeAdsSuccess()
                SKPaymentQueue.default().finishTransaction(transaction)
            case .restored:
                // the user restored their IAP!
                RemoveAdsManager.restoreRemoveAdsSuccess()
                SKPaymentQueue.default().finishTransaction(transaction)
            case .failed:
                // The transaction failed!
                RemoveAdsManager.removeAdsFailure()
                // finish the transaction
                SKPaymentQueue.default().finishTransaction(transaction)
            case .deferred:
                // This happens when the IAP needs an external action
                // in order to proceeded, like Ask to Buy
                RemoveAdsManager.removeAdsDeferred()
                break
            }
        }
    }

}

Lastly, you need to add some way for the user to start the purchase and call RemoveAdsManager.removeAds() and start a restore and call RemoveAdsManager.restoreRemoveAds(), like a button somewhere! Keep in mind that, per the App Store guidelines, you do need to provide a button to restore purchases somewhere.

Submitting for review

The last thing to do is submit your IAP for review on App Store Connect! For detailed instructions on doing that, you can follow the last part of my Objective-C answer, under the Submitting for review header.

For those who want to substrat two timestamps (instead of dates), there is a similar solution:

SELECT ( CAST( date2 AS DATE ) - CAST( date1 AS DATE ) ) * 1440 AS minutesInBetween
FROM ...

or

SELECT ( CAST( date2 AS DATE ) - CAST( date1 AS DATE ) ) * 86400 AS secondsInBetween
FROM ...

Since none of the other answers worked for me I did it using this hack:

$ cd /yourfolder
svn co https://path-to-folder-which-has-your-files/ --depth files

This will create a new local folder which has only the files from the remote path. Then you can do a symbolic link to the files you want to have here.

This is probably not the ultimate solution, and it requires that you use the TabLayout together with a ViewPager, but this is how I solved it:

void selectPage(int pageIndex)
{
    viewPager.setCurrentItem(pageIndex);
    tabLayout.setupWithViewPager(viewPager);
}

I tested how big the performance impact of using this code is by first looking at the CPU- and memory monitors in Android Studio while running the method, then comparing it to the load that was put on the CPU and memory when I navigated between the pages myself (using swipe gestures), and the difference isn't significantly big, so at least it's not a horrible solution...

Hope this helps someone!

I tried restarting Xcode (7) and nothing (the have you tried switching it off and on again of iOS development for me :-)). I then tried by restarting my box and that worked.

In my case the script was failing when copying a file from a location to another one. I think it could have been related to Finder screwing with writing rights over certain folders.

env: django 2.1.7

view:

dict_objs[query_obj.id] = {'obj': query_obj, 'tag': str_tag}
return render(request, 'obj.html', {'dict_objs': dict_objs})

template:

{% for obj_id,dict_obj in dict_objs.items %}
<td>{{ dict_obj.obj.obj_name }}</td>
<td style="display:none">{{ obj_id }}</td>
<td>{{ forloop.counter }}</td>
<td>{{ dict_obj.obj.update_timestamp|date:"Y-m-d H:i:s"}}</td>

No. REST has nothing to do with URI naming conventions. If you include these conventions as part of your API, out-of-band, instead of only via hypertext, then your API is not RESTful.

For more information, see http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven

First you can get the rowid of the selected row with respect of getGridParam method and 'selrow' as the parameter and then you can use getCell to get the cell value from the corresponding column:

var myGrid = $('#list'),
    selRowId = myGrid.jqGrid ('getGridParam', 'selrow'),
    celValue = myGrid.jqGrid ('getCell', selRowId, 'columnName');

The 'columnName' should be the same name which you use in the 'name' property of the colModel. If you need values from many column of the selected row you can use getRowData instead of getCell.

you can use jquery dialog widget

http://jqueryui.com/demos/dialog/

Right click on your root folder, find in folder.

you can do it using isin(dict) method:

In [74]: df1[~df1.isin(df2.to_dict('l')).all(1)]
Out[74]:
   col1  col2
3     4    13
4     5    14

Explanation:

In [75]: df2.to_dict('l')
Out[75]: {'col1': [1, 2, 3], 'col2': [10, 11, 12]}

In [76]: df1.isin(df2.to_dict('l'))
Out[76]:
    col1   col2
0   True   True
1   True   True
2   True   True
3  False  False
4  False  False

In [77]: df1.isin(df2.to_dict('l')).all(1)
Out[77]:
0     True
1     True
2     True
3    False
4    False
dtype: bool

If your form submission takes them to another page (as I assume it does, hence the triggering of beforeunload), you could try to change your form submission to an ajax call. This way, they won't leave your page when they submit the form and you can use your beforeunload binding code as you wish.

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.

What the other thing you can do is go to: /etc/sudoers

There add the following line which gives the permission to that user www-data ALL=(ALL:ALL) ALL Why www-data ? this is because apache is running by this user name.

Incase if your user is different then try username ALL=(ALL:ALL) ALL

This worked for me.

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

Like that. Except char hi=hello; should be char hi=hello.charAt(0). (Don't forget your break; statements).

Google declares that this is not a failure, but some "misleading error reports". This bug will be fixed in version 40 of chrome.

Have a look at: Greybox

It's an awesome version of lightbox that supports forms, external web pages as well as the traditional images and slideshows. It works perfectly from a link on a webpage.

You will find many information on how to use Greybox and also some great examples. Cheers Kara

If you don't want to use JavaCV this works for me...

Step 1- Download the Resources

Download OpenCV Android SDK from http://opencv.org/downloads.html

Step 2 - Copying the OpenCV binaries into your APK

Copy libopencv_info.so & libopencv_java.so from

OpenCV-2.?.?-android-sdk -> sdk -> native -> libs -> armeabi-v7a

to

Project Root -> Your Project -> lib - > armeabi-v7a

Zip the lib folder up and rename that zip to whatever-v7a.jar.

Copy this .jar file and place it in here in your project

Project Root -> Your Project -> libs

Add this line to your projects build.gradle in the dependencies section

compile files('libs/whatever-v7a.jar')

When you compile now you will probably see your .apk is about 4mb bigger.

(Repeat for "armeabi" if you want to support ARMv6 too, likely not needed anymore.)

Step 3 - Adding the java sdk to your project

Copy the java folder from here

OpenCV-2.?.?-android-sdk -> sdk

to

Project Root -> Your Project -> libs (Same place as your .jar file);

(You can rename the 'java' folder name to 'OpenCV')

In this freshly copied folder add a typical build.gradle file; I used this:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android-library'

repositories {
    mavenCentral();
}

android {
    compileSdkVersion 19
    buildToolsVersion "19"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 19
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
}

In your Project Root settings.gradle file change it too look something like this:

include ':Project Name:libs:OpenCV', ':Project Name'

In your Project Root -> Project Name -> build.gradle file in the dependencies section add this line:

compile project(':Project Name:libs:OpenCV')

Step 4 - Using OpenCV in your project

Rebuild and you should be able to import and start using OpenCV in your project.

import org.opencv.android.OpenCVLoader;
...
if (!OpenCVLoader.initDebug()) {}

I know this if a bit of hack but I figured I would post it anyway.

opt is new for ruby 1.9. The various options are documented in IO.new : www.ruby-doc.org/core/IO.html

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

There is a solution provided to this problem in some of the OTN forums (https://kr.forums.oracle.com/forums/thread.jspa?messageID=3699989). But, the root cause of the problem is not explained. Following is my attempt to explain the root cause of the problem.

The Oracle JDBC drivers communicate with the Oracle server in a secure way. The drivers use the java.security.SecureRandom class to gather entropy for securing the communication. This class relies on the native platform support for gathering the entropy.

Entropy is the randomness collected/generated by an operating system or application for use in cryptography or other uses that require random data. This randomness is often collected from hardware sources, either from the hardware noises, audio data, mouse movements or specially provided randomness generators. The kernel gathers the entropy and stores it is an entropy pool and makes the random character data available to the operating system processes or applications through the special files /dev/random and /dev/urandom.

Reading from /dev/random drains the entropy pool with requested amount of bits/bytes, providing a high degree of randomness often desired in cryptographic operations. In case, if the entropy pool is completely drained and sufficient entropy is not available, the read operation on /dev/random blocks until additional entropy is gathered. Due to this, applications reading from /dev/random may block for some random period of time.

In contrast to the above, reading from the /dev/urandom does not block. Reading from /dev/urandom, too, drains the entropy pool but when short of sufficient entropy, it does not block but reuses the bits from the partially read random data. This is said to be susceptible to cryptanalytical attacks. This is a theorotical possibility and hence it is discouraged to read from /dev/urandom to gather randomness in cryptographic operations.

The java.security.SecureRandom class, by default, reads from the /dev/random file and hence sometimes blocks for random period of time. Now, if the read operation does not return for a required amount of time, the Oracle server times out the client (the jdbc drivers, in this case) and drops the communication by closing the socket from its end. The client when tries to resume the communication after returning from the blocking call encounters the IO exception. This problem may occur randomly on any platform, especially, where the entropy is gathered from hardware noises.

As suggested in the OTN forum, the solution to this problem is to override the default behaviour of java.security.SecureRandom class to use the non-blocking read from /dev/urandom instead of the blocking read from /dev/random. This can be done by adding the following system property -Djava.security.egd=file:///dev/urandom to the JVM. Though this is a good solution for the applications like the JDBC drivers, it is discouraged for applications that perform core cryptographic operations like crytographic key generation.

Other solutions could be to use different random seeder implementations available for the platform that do not rely on hardware noises for gathering entropy. With this, you may still require to override the default behaviour of java.security.SecureRandom.

Increasing the socket timeout on the Oracle server side can also be a solution but the side effects should be assessed from the server point of view before attempting this.

I used the above command line as follow: update TABLE-NAME set FIELD = replace(FIELD, 'And', 'and'); the purpose was to replace And with and ("A" should be lowercase). The problem is it cannot find the "And" in database, but if I use like "%And%" then it can find it along with many other ands that are part of a word or even the ones that are already lowercase.

Try using an infinite generator.

from itertools import repeat
inputs = (get_input("Is this ok? (y/n)") for _ in repeat(None))
response = (i.lower()=="y" for i in inputs if i.lower() in ("y", "n"))

while True:
    #snip: print out current state
    if next(response):
        break
    #do more processing with menus and stuff

public DataTable ImportExceltoDatatable(string filepath)
{
    // string sqlquery= "Select * From [SheetName$] Where YourCondition";
    string sqlquery = "Select * From [SheetName$] Where Id='ID_007'";
    DataSet ds = new DataSet();
    string constring = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepath + ";Extended Properties=\"Excel 12.0;HDR=YES;\"";
    OleDbConnection con = new OleDbConnection(constring + "");
    OleDbDataAdapter da = new OleDbDataAdapter(sqlquery, con);
    da.Fill(ds);
    DataTable dt = ds.Tables[0];
    return dt;
}

To prevent the jump, this is what I used

export function toggleBodyScroll(disable) {
  if (!window.tempScrollTop) {
    window.tempScrollTop = window.pageYOffset; 
    // save the current position in a global variable so I can access again later

  }
  if (disable) {
    document.body.classList.add('disable-scroll');
    document.body.style.top = `-${window.tempScrollTop}px`;
  } else {
    document.body.classList.remove('disable-scroll');
    document.body.style.top = `0px`;
    window.scrollTo({top: window.tempScrollTop});
    window.tempScrollTop = 0;
  }
}

and in my css

.disable-scroll {
  height: 100%;
  overflow: hidden;
  width: 100%;
  position: fixed;
}

You can remove useless parts and / or change indexes if you do not need them.

In VBA, the != operator is the Not operator, like this:

If Not strTest = "" Then ...

Its kind of relative path Instead of the below code

import { Something } from "../../../../../lib/src/[browser/server/universal]/...";

We can avoid the "../../../../../" its looking odd and not readable too.

So Typescript config file have answer for the same. Just specify the baseUrl, config will take care of your relative path.

way to config: tsconfig.json file add the below properties.

"baseUrl": "src",
    "paths": {
      "@app/*": [ "app/*" ],
      "@env/*": [ "environments/*" ]
    }

So Finally it will look like below

import { Something } from "@app/src/[browser/server/universal]/...";

Its looks simple,awesome and more readable..

Here is a way to do it while passing in an extra argument:

https://stackoverflow.com/a/17813797/4533488 (thanks to Denis Pshenov)

<div ng-repeat="group in groups">
    <li ng-repeat="friend in friends | filter:weDontLike(group.enemy.name)">
        <span>{{friend.name}}</span>
    <li>
</div>

With the backend:

$scope.weDontLike = function(name) {
    return function(friend) {
        return friend.name != name;
    }
}

.

And yet another way with an in-template filter only:

https://stackoverflow.com/a/12528093/4533488 (thanks to mikel)

<div ng:app>
  <div ng-controller="HelloCntl">
    <ul>
       <li ng-repeat="friend in friends | filter:{name:'!Adam'}">
            <span>{{friend.name}}</span>
            <span>{{friend.phone}}</span>
        </li>
    </ul>
</div>

The NUMBER type can be specified in different styles:

                Resulting  Resulting  Precision
Specification   Precision  Scale      Check      Comment
-------------------------------------------------------------------------------
NUMBER          NULL       NULL       NO         'maximum range and precision',
                                                 values are stored 'as given'
NUMBER(P, S)    P          S          YES        Error code: ORA-01438
NUMBER(P)       P          0          YES        Error code: ORA-01438
NUMBER(*, S)    38         S          NO

Where the precision is the total number of digits and scale is the number of digits right or left (negative scale) of the decimal point.

Oracle specifies ORA-01438 as

value larger than specified precision allowed for this column

As noted in the table, this integrity check is only active if the precision is explicitly specified. Otherwise Oracle silently rounds the inserted or updated value using some unspecified method.

I think what you have missed here is this:

https://maven.apache.org/settings.html#Servers

The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.

This is the prefered way of using custom repos. So probably what is happening is that the url of this repo is in settings.xml of the build server.

Once you get hold of the url and credentials, you can put them in your machine here: ~/.m2/settings.xml like this:

<settings ...> 

        .
        .
        .
        <servers>
            <server>
              <id>internal-repository-group</id>
              <username>YOUR-USERNAME-HERE</username>
              <password>YOUR-PASSWORD-HERE</password>
            </server>
        </servers>
</settings>

EDIT:

You then need to refer this repository into project POM. The id internal-repository-group can be used in every project. You can setup multiple repos and credentials setting using different IDs in settings xml.

The advantage of this approach is that project can be shared without worrying about the credentials and don't have to mention the credentials in every project.

Following is a sample pom of a project using "internal-repository-group"

<repositories>
    <repository>
        <id>internal-repository-group</id>
        <name>repo-name</name>
        <url>http://project.com/yourrepourl/</url>
        <layout>default</layout>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
        </releases>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
        </snapshots>
    </repository>
</repositories>

This is how I organized my application's static resources.

If all other methods are not working for you... Try

npm link package_name

e.g

npm link webpack
npm link autoprefixer

Here is an example of accessing the ith index of a std::vector using an std::iterator within a loop which does not require incrementing two iterators.

std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
    int ith = it - strs.begin();
    if(ith == nth) {
        printf("Iterator within  a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
    }
}

Without a for-loop

it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());

and using at method:

printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());

I know this has already been answered, but here is an example for the people who are trying to use SQL Server Types in a vb project:

            Imports System
            Imports System.IO
            Imports System.Runtime.InteropServices

            Namespace SqlServerTypes
                Public Class Utilities



                    <DllImport("kernel32.dll", CharSet:=CharSet.Auto, SetLastError:=True)>
                    Public Shared Function LoadLibrary(ByVal libname As String) As IntPtr

                    End Function

                    Public Shared Sub LoadNativeAssemblies(ByVal rootApplicationPath As String)
                        Dim nativeBinaryPath = If(IntPtr.Size > 4, Path.Combine(rootApplicationPath, "SqlServerTypes\x64\"), Path.Combine(rootApplicationPath, "SqlServerTypes\x86\"))
                        LoadNativeAssembly(nativeBinaryPath, "msvcr120.dll")
                        LoadNativeAssembly(nativeBinaryPath, "SqlServerSpatial140.dll")
                    End Sub

                    Private Shared Sub LoadNativeAssembly(ByVal nativeBinaryPath As String, ByVal assemblyName As String)
                        Dim path = System.IO.Path.Combine(nativeBinaryPath, assemblyName)
                        Dim ptr = LoadLibrary(path)

                        If ptr = IntPtr.Zero Then
                            Throw New Exception(String.Format("Error loading {0} (ErrorCode: {1})", assemblyName, Marshal.GetLastWin32Error()))
                        End If
                    End Sub
                End Class
            End Namespace

I discovered that there is a second portion of the answer to this.

The first portion helped me, but I still had a space to the right of my type=number input. I had zeroed out the margin on the input, but apparently I had to zero out the margin on the spinner as well.

This fixed it:

input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
    -webkit-appearance: none;
    margin: 0;
}

You can:

• Either, use an <input type="submit" ..>, instead of that button.
• or, Use a bit of javascript, to get a hold of form object (using name or id), and call submit(..) on it. Eg: form.submit(). Attach this code to the button click event. This will serialise the form parameters and execute a GET or POST request as specified in the form's method attribute.

If you're dealing with a single element preferably you should use the id selector as stated on GenericTypeTea answer and get the name like $("#id").attr("name");.

But if you want, as I did when I found this question, a list with all the input names of a specific class (in my example a list with the names of all unchecked checkboxes with .selectable-checkbox class) you could do something like:

var listOfUnchecked = $('.selectable-checkbox:unchecked').toArray().map(x=>x.name);

or

var listOfUnchecked = [];
$('.selectable-checkbox:unchecked').each(function () {
    listOfUnchecked.push($(this).attr('name'));
});

I would suggest this one:

PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "tag");
wl.acquire();

The flag ACQUIRE_CAUSES_WAKEUP is explained like that:

Normal wake locks don't actually turn on the illumination. Instead, they cause the illumination to remain on once it turns on (e.g. from user activity). This flag will force the screen and/or keyboard to turn on immediately, when the WakeLock is acquired. A typical use would be for notifications which are important for the user to see immediately.

Also, make sure you have the following permission in the AndroidManifewst.xml file:

<uses-permission android:name="android.permission.WAKE_LOCK" />

code {_x000D_
    background: black;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
}

<p>Some text <code>A<br />B<br />C<br />D</code> continues afterward.</p>

Tested and works in Safari 5 and IE6+.

Follow these steps when deploying the Windows Service, don't lose time:

1. Run command prompt by the Admin right

2. Insure about release mode when compilling in your IDE

3. Give a type to your project installer on design view

4. Select authentication type in accordance the case

5. Insure about software dependencies: If you are using a certificate install it correctly

6. Go your console write this:

   C:\Windows\Microsoft.NET\Framework\yourRecentVersion\installutil.exe c:\yourservice.exe

there is a hidden -i argument before the exe path -i c:\ you can use -u for uninstallling

7. Look your .exe path to seem log file. You can use event viewer to observing in the feature

Warning you get is done by compiler, not by library (or utility method).

Simplest way using Jackson directly would be:

HashMap<String,Object> props;

// src is a File, InputStream, String or such
props = new ObjectMapper().readValue(src, new TypeReference<HashMap<String,Object>>() {});
// or:
props = (HashMap<String,Object>) new ObjectMapper().readValue(src, HashMap.class);
// or even just:
@SuppressWarnings("unchecked") // suppresses typed/untype mismatch warnings, which is harmless
props = new ObjectMapper().readValue(src, HashMap.class);

Utility method you call probably just does something similar to this.

Isn't the platform solution for this implementation to use a context menu that shows on a long press?

Is the question author aware of context menus? Stacking up buttons in a listview has performance implications, will clutter your UI and violate the recommended UI design for the platform.

On the flipside; context menus - by nature of not having a passive representation - are not obvious to the end user. Consider documenting the behaviour?

This guide should give you a good start.

http://www.mikeplate.com/2010/01/21/show-a-context-menu-for-long-clicks-in-an-android-listview/

strcat(str1, str2) appends str2 after str1. It requires str1 to have enough space to hold str2. In you code, str1 and str2 are all string constants, so it should not work. You may try this way:

char str1[1024];
char *str2 = "kkkk";
strcpy(str1, "ssssss");
strcat(str1, str2);
printf("%s", str1);

The default value table only applies to initializing a variable.

Per the linked page, the following two methods of initialization are equivalent...

int x = 0;
int x = new int();

In your code, you merely defined the variable, but never initialized the object.

Try adding the current user to docker group:

sudo usermod -aG docker $USER

Then log out and login.

I found this one useful. For VB.NET developers:

    Public Shared Function GetFromFileName(ByVal fileName As String) As String
        Return GetFromExtension(Path.GetExtension(fileName).Remove(0, 1))
    End Function

    Public Shared Function GetFromExtension(ByVal extension As String) As String
        If extension.StartsWith("."c) Then
            extension = extension.Remove(0, 1)
        End If

        If MIMETypesDictionary.ContainsKey(extension) Then
            Return MIMETypesDictionary(extension)
        End If

        Return "unknown/unknown"

For UTF-16LE with BOM if you use tab characters as your delimiters instead of commas Excel will recognise the fields. The reason it works is that Excel actually ends up using its Unicode *.txt parser.

Caveat: If the file is edited in Excel and saved, it will be saved as tab-delimited ASCII. The problem now is that when you re-open the file Excel assumes it's real CSV (with commas), sees that it's not Unicode, so parses it as comma-delimited - and hence will make a hash of it!

Update: The above caveat doesn't appear to be happening for me today in Excel 2010 (Windows) at least, although there does appear to be a difference in saving behaviour if:

• you edit and quit Excel (tries to save as 'Unicode *.txt')

compared to:

• editing and closing just the file (works as expected).

@NathanClement was a bit faster. Yet, here is the complete code (slightly more elaborate):

Option Explicit

Public Sub ExportWorksheetAndSaveAsCSV()

Dim wbkExport As Workbook
Dim shtToExport As Worksheet

Set shtToExport = ThisWorkbook.Worksheets("Sheet1")     'Sheet to export as CSV
Set wbkExport = Application.Workbooks.Add
shtToExport.Copy Before:=wbkExport.Worksheets(wbkExport.Worksheets.Count)
Application.DisplayAlerts = False                       'Possibly overwrite without asking
wbkExport.SaveAs Filename:="C:\tmp\test.csv", FileFormat:=xlCSV
Application.DisplayAlerts = True
wbkExport.Close SaveChanges:=False

End Sub

I know this is an old post, but I think this is a very important topic, especially nowadays where we have 10M+ records and talk about terabytes of data.

I will also weight in with the following observations. I have about 45M records in my table ([data]), and about 300 records in my [cats] table. I have extensive indexing for all of the queries I am about to talk about.

Consider Example 1:

UPDATE d set category = c.categoryname
FROM [data] d
JOIN [cats] c on c.id = d.catid

versus Example 2:

UPDATE d set category = (SELECT TOP(1) c.categoryname FROM [cats] c where c.id = d.catid)
FROM [data] d

Example 1 took about 23 mins to run. Example 2 took around 5 mins.

So I would conclude that sub-query in this case is much faster. Of course keep in mind that I am using M.2 SSD drives capable of i/o @ 1GB/sec (thats bytes not bits), so my indexes are really fast too. So this may affect the speeds too in your circumstance

If its a one-off data cleansing, probably best to just leave it run and finish. I use TOP(10000) and see how long it takes and multiply by number of records before I hit the big query.

If you are optimizing production databases, I would strongly suggest pre-processing data, i.e. use triggers or job-broker to async update records, so that real-time access retrieves static data.

One angle not so far mentioned is tool sets used for editing the code.

Using Visual Studio Code along with the Extension from lukehoban called Go will do some auto-magic for you. The Go extension automatically runs gofmt, golint etc, and removes and adds import entries. So at least that part is now automatic.

I will admit its not 100% of the solution to the question, but however useful enough.

You say in a comment you want to get "15.09.2016".

For this, use Date and DateFormatter:

let date = Date()
let formatter = DateFormatter()

Give the format you want to the formatter:

formatter.dateFormat = "dd.MM.yyyy"

Get the result string:

let result = formatter.string(from: date)

Set your label:

label.text = result

Result:

15.09.2016

Honestly, I had problems with bundler circular dependencies and the best way to go is rm -rf .bundle. Save yourselves the headache and just use the hammer.

try following to see all instances of python

whereis python
which python

Then remove all instances using:

sudo apt autoremove python

repeat sudo apt autoremove python(for all versions) that should do it, then install Anaconda and manage Pythons however you like if you need to reinstall it.

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

If non of above works for you, then it is worth to check if you have any packages under Preference > Editor > Code Style > Java > Imports > Packages to Use Import with "*"

The problem is in the Cordova settings.

Note this:

iPhone Distribution has been manually specified

This didn’t make any sense to me, since I had set the project to auto sign in xcode. Like you, the check and uncheck didn’t work. But then I read the last file path given and followed it. The file path is APP > Platforms > ios > Cordova > build-release.xconfig

And in the file, iPhone Distribution is explicitly set for CODE_SIGN_IDENTITY.

Change:

CODE_SIGN_IDENTITY = iPhone Distribution
CODE_SIGN_IDENTITY[sdk=iphoneos*] = iPhone Distribution

To:

CODE_SIGN_IDENTITY = iPhone Developer
CODE_SIGN_IDENTITY[sdk=iphoneos*] = iPhone Developer

It a simple thing, and the error message does make it clear that iPhone Distribution has been manually specified, but it doesn’t really say where unless you follow the path. I looked and fiddled with xcode for about three hours trying to figure this out. Hopes this helps anyone in the future.

The return type depends on the server, sometimes the response is indeed a JSON array but sent as text/plain

Setting the accept headers in the request should get the correct type:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

which can then be serialized to a JSON list or array. Thanks for the comment from @svick which made me curious that it should work.

The Exception I got without configuring the accept headers was System.Net.Http.UnsupportedMediaTypeException.

Following code is cleaner and should work (untested, but works in my case):

    var client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    var response = await client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs");
    var model = await response.Content.ReadAsAsync<List<Job>>();

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

If you don't need the output in real time (i.e. as the program is writing it) you could add

type windows-dir.txt

after that line.

Set minDate to current date in jQuery Datepicker :

$("input.DateFrom").datepicker({
    minDate: new Date()
});

Lets say your HTML looks something like this:

<div class="box">
    <!-- stuff -->
    <p class="bet_time">Bet 5 days ago</p>
</div>

Then, with CSS, you can make that text appear in the bottom right like so:

.box {
    position:relative;
}
.bet_time {
    position:absolute;
    bottom:0;
    right:0;
}

The way this works is that absolutely positioned elements are always positioned with respect to the first relatively positioned parent element, or the window. Because we set the box's position to relative, .bet_time positions its right edge to the right edge of .box and its bottom edge to the bottom edge of .box

in windows: if you have mysql workbench. Go to server status. find the location of running server file in my case it was:

C:\ProgramData\MySQL\MySQL Server 5.7

open my.ini file and find the buffer_pool_size. Set the value high. default value is 8M. This is how i fixed this problem

I was getting the same problem when running my project. On checking the files structure, I realised that Spring's xml file was inside the project's package and thus couldn't be found. I put it outside the package and it worked just fine.

At the time of my writing this answer, the accepted answer to this question appears to state that browsers are not required to delete a cookie when receiving a replacement cookie whose Expires value is in the past. That claim is false. Setting Expires to be in the past is the standard, spec-compliant way of deleting a cookie, and user agents are required by spec to respect it.

Using an Expires attribute in the past to delete a cookie is correct and is the way to remove cookies dictated by the spec. The examples section of RFC 6255 states:

Finally, to remove a cookie, the server returns a Set-Cookie header with an expiration date in the past. The server will be successful in removing the cookie only if the Path and the Domain attribute in the Set-Cookie header match the values used when the cookie was created.

The User Agent Requirements section includes the following requirements, which together have the effect that a cookie must be immediately expunged if the user agent receives a new cookie with the same name whose expiry date is in the past

11. If [when receiving a new cookie] the cookie store contains a cookie with the same name, domain, and path as the newly created cookie:

    1. ...
    2. ...
    3. Update the creation-time of the newly created cookie to match the creation-time of the old-cookie.
    4. Remove the old-cookie from the cookie store.

12. Insert the newly created cookie into the cookie store.

A cookie is "expired" if the cookie has an expiry date in the past.

The user agent MUST evict all expired cookies from the cookie store if, at any time, an expired cookie exists in the cookie store.

Points 11-3, 11-4, and 12 above together mean that when a new cookie is received with the same name, domain, and path, the old cookie must be expunged and replaced with the new cookie. Finally, the point below about expired cookies further dictates that after that is done, the new cookie must also be immediately evicted. The spec offers no wiggle room to browsers on this point; if a browser were to offer the user the option to disable cookie expiration, as the accepted answer suggests some browsers do, then it would be in violation of the spec. (Such a feature would also have little use, and as far as I know it does not exist in any browser.)

Why, then, did the OP of this question observe this approach failing? Though I have not dusted off a copy of Internet Explorer to check its behaviour, I suspect it was because the OP's Expires value was malformed! They used this value:

expires=Thu, Jan 01 1970 00:00:00 UTC;

However, this is syntactically invalid in two ways.

The syntax section of the spec dictates that the value of the Expires attribute must be a

rfc1123-date, defined in [RFC2616], Section 3.3.1

Following the second link above, we find this given as an example of the format:

Sun, 06 Nov 1994 08:49:37 GMT

and find that the syntax definition...

1. requires that dates be written in day month year format, not month day year format as used by the question asker.

   Specifically, it defines rfc1123-date as follows:

   rfc1123-date = wkday "," SP date1 SP time SP "GMT"
   

   and defines date1 like this:

   date1        = 2DIGIT SP month SP 4DIGIT
                ; day month year (e.g., 02 Jun 1982)
   

and

2. doesn't permit UTC as a timezone.

   The spec contains the following statement about what timezone offsets are acceptable in this format:

   All HTTP date/time stamps MUST be represented in Greenwich Mean Time (GMT), without exception.

   What's more if we dig deeper into the original spec of this datetime format, we find that in its initial spec in https://tools.ietf.org/html/rfc822, the Syntax section lists "UT" (meaning "universal time") as a possible value, but does not list not UTC (Coordinated Universal Time) as valid. As far as I know, using "UTC" in this date format has never been valid; it wasn't a valid value when the format was first specified in 1982, and the HTTP spec has adopted a strictly more restrictive version of the format by banning the use of all "zone" values other than "GMT".

If the question asker here had instead used an Expires attribute like this, then:

expires=Thu, 01 Jan 1970 00:00:00 GMT;

then it would presumably have worked.

How about just an extension method on HashSet?

public static void AddOrThrow<T>(this HashSet<T> hash, T item)
{
    if (!hash.Add(item))
        throw new ValueExistingException();
}

class A{
  public void methodA(){
    new B().methodB();
    //or
    B.methodB1();
  }
}

class B{
  //instance method
  public void methodB(){
  }
  //static method
  public static  void methodB1(){
  }
}

Create your partial view something like:

@model YourModelType
<div>
  <!-- HTML to render your object -->
</div>

Then in your view use:

@Html.Partial("YourPartialViewName", Model)

If you do not want a strongly typed partial view remove the @model YourModelType from the top of the partial view and it will default to a dynamic type.

Update

The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/ in the path below.

@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)

Avoid direct references to '@@ERROR'. It's a flighty little thing that can be lost.

Declare @ErrorCode int;
... perform stuff ...
Set @ErrorCode = @@ERROR;
... other stuff ...
if @ErrorCode ...... 

I have used this code which worked

                if (element.HasAttributes) {

                    foreach(var attr in element.Attributes().Reverse())
                    {

                        if (depth > 1)
                        {
                            elements_upper_hierarchy_text = "";
                            foreach (var ancest  in element.Ancestors().Reverse())
                            {
                                elements_upper_hierarchy_text += ancest.Name + "_";
                            }// foreach(var ancest  in element.Ancestors())

                        }//if (depth > 1)
                        xml_taglist_report += " " + depth  + " " + elements_upper_hierarchy_text+ element.Name + "_" + attr.Name +"(" + attr.Name +")" + "   =   " + attr.Value + "\r\n";
                    }// foreach(var attr in element.Attributes().Reverse())

                }// if (element.HasAttributes) {

var isWin64 = process.env.hasOwnProperty('ProgramFiles(x86)');

its very simple

just write:

//first create table named test....

create table test (name varchar2(10),age number(5));

//when you run the above code a table will be created....

//now we have to insert a name & an age..

Make sure age will be inserted via opening a form that seeks our help to enter the value in it

insert into test values('Deepak', :age);

//now run the above code and you'll get "1 row inserted" output...

/now run the select query to see the output

select * from test;

//that's all ..Now i think no one has any queries left over accepting a user data...

The advantage of passing an owner handle is that the FolderBrowserDialog will not be modal to that window. This prevents the user from interacting with your main application window while the dialog is active.

there are 2 solutions:

visit this jsfiddle

in your css you can add this:
     .input-disabled{background-color:#EBEBE4;border:1px solid #ABADB3;padding:2px 1px;}

in your js do something like this:
     $('#test').attr('readonly', true);
     $('#test').addClass('input-disabled');

Hope this help.

Another way is using hidden input field as mentioned by some of the comments. However bear in mind that, in the backend code, you need to make sure you validate this newly hidden input at correct scenario. Hence I'm not recommend this way as it will create more bugs if its not handle properly.

a += b

is in this case the same as

a = a + b

In this case cnt += 1 means that cnt is increased by one.

Note that the code you pasted will loop indefinitely if cnt > 0 and len(aStr) > 1.

Edit: quote Carl Meyer: ``[..] the answer is misleadingly mostly correct. There is a subtle but very significant difference between + and +=, see Bastien's answer.''.

Use strtotime to generate a timestamp from the given string (interpreted as local time) and use gmdate to get it as a formatted UTC date back.

Example

As requested, here’s a simple example:

echo gmdate('d.m.Y H:i', strtotime('2012-06-28 23:55'));

Supposedly you can do this on windows with the growl for windows javascript API:

http://ajaxian.com/archives/growls-for-windows-and-a-web-notification-api

Your users will have to install growl though.

Eventually this is going to be part of google gears, in the form of the NotificationAPI:

http://code.google.com/p/gears/wiki/NotificationAPI

So I would recommend using the growl approach for now, falling back to window title updates if possible, and already engineering in attempts to use the Gears Notification API, for when it eventually becomes available.

<html>
<head>
<script type="text/javascript">
var number = 123;
var string = "abcd";

function docWrite(variable) {
    document.write(variable);
}
</script>
</head>

<body>
<h1>the value for number is: <script>docWrite(number)</script></h1>

<h2>the text is: <script>docWrite(string)</script> </h2>
</body>
</html>

You can shorten document.write but can't avoid <script> tag

One thing I noticed is you can't add a gradient to a UILabel without clearing the text. One simple workaround is to use a UIButton and disable user interaction.

import * as express from "express";

This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.

In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

I was facing such a problem, look at the picture below

and here is its HTML

<tr class="li1">
    <td valign="top">1.</td>
    <td colspan="5" valign="top">
        <p>How to build e-book learning environment</p>
    </td>
</tr>

so I fix it by changing valign Attribute in both td tags to baseline

and it worked

here is the result

hope this help you

I does not watch here an old CSS-trick for <div> inside <td>. Hence I remind: simple set some minimal value for width, but what-you-need for min-width. For example:

<div style="width: 3px; min-width: 99%;">

The td's width, in that case, is up to you.

Use the "Go To Find Combo Box" with the ">of" command. CTRL+/ or CTRL+D are the standard hotkeys.

For example, go to the combo box (CTRL+/) and type: >of MyClassName. As you type, intellisense will refine the options in the dropdown.

In my experience, this is faster than Navigate To and doesn't bring up another dialog to deal with. Also, this combo box has a lot of other nifty little shortcut commands:

Using the Go To Find Combo Box

This textbox used to be the default on the Standard toolbar in Visual Studio. It was removed in Visual Studio 2012, so you have to add it back using menu Tools ? Customize. The hotkeys may have changed too: I'm not sure since mine are all customized.

In order to vertically and horizontally center an element we can also use below mentioned properties.

This CSS property aligns-items vertically and accepts the following values:

flex-start: Items align to the top of the container.

flex-end: Items align to the bottom of the container.

center: Items align at the vertical center of the container.

baseline: Items display at the baseline of the container.

stretch: Items are stretched to fit the container.

This CSS property justify-content , which aligns items horizontally and accepts the following values:

flex-start: Items align to the left side of the container.

flex-end: Items align to the right side of the container.

center: Items align at the center of the container.

space-between: Items display with equal spacing between them.

space-around: Items display with equal spacing around them.

If you forget your password for SQL plus 10g then follow the steps :

1. START
2. Type RUN in the search box
3. Type 'cnc' in the box captioned as OPEN and a black box will appear 4.There will be some text already in the box. (C:\Users\admin>) Just beside that start typing 'sqlplus/nolog' press ENTER key
4. On the next line type 'conn sys/change_on_install as sysdba' (press ENTER) 6.(in the next line after sql-> type) 'alter user scott account unlock' .
5. Now open your slpplus and type user name as 'scott' and password as 'tiger'.

If it asks your old password then type the one you have given while installing.

What SSL private key should be sent along with the client certificate?

None of them :)

One of the appealing things about client certificates is it does not do dumb things, like transmit a secret (like a password), in the plain text to a server (HTTP basic_auth). The password is still used to unlock the key for the client certificate, its just not used directly to during exchange or tp authenticate the client.

Instead, the client chooses a temporary, random key for that session. The client then signs the temporary, random key with his cert and sends it to the server (some hand waiving). If a bad guy intercepts anything, its random so it can't be used in the future. It can't even be used for a second run of the protocol with the server because the server will select a new, random value, too.

Fails with: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

Use TLS 1.0 and above; and use Server Name Indication.

You have not provided any code, so its not clear to me how to tell you what to do. Instead, here's the OpenSSL command line to test it:

openssl s_client -connect www.example.com:443 -tls1 -servername www.example.com \
    -cert mycert.pem -key mykey.pem -CAfile <certificate-authority-for-service>.pem

You can also use -CAfile to avoid the “verify error:num=20”. See, for example, “verify error:num=20” when connecting to gateway.sandbox.push.apple.com.

For Scroll View:

if after adding android:windowSoftInputMode="stateHidden|adjustPan" in your Android Manifest and still does not work.

It may be affected because when the keyboard appears, it will be into a scroll view and if your button/any objects is not in your scroll view then the objects will follow the keyboard and move its position.

Check out your xml where your button is and make sure it is under your scroll View bracket and not out of it.

Hope this helps out. :D

toISOString() will return current UTC time only not the current local time. If you want to get the current local time in yyyy-MM-ddTHH:mm:ss.SSSZ format then you should get the current time using following two methods

Method 1:

document.write(new Date(new Date().toString().split('GMT')[0]+' UTC').toISOString());

Method 2:

document.write(new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString());

to build on what Martin Kuzdowicz posted above. I use the following to do an update using mongoose and a deep merge of json objects. Along with the model.save() function in mongoose this allows mongoose to do a full validation even one that relies on other values in the json. it does require the deepmerge package https://www.npmjs.com/package/deepmerge. But that is a very light weight package.

var merge = require('deepmerge');

app.put('url', (req, res) => {

    const modelId = req.body.model_id;

    MyModel.findById(modelId).then((model) => {
        return Object.assign(model, merge(model.toObject(), req.body));
    }).then((model) => {
        return model.save();
    }).then((updatedModel) => {
        res.json({
            msg: 'model updated',
            updatedModel
        });
    }).catch((err) => {
        res.send(err);
    });
});

You can also use the Generate SQL Server Scripts Wizard to help guide the creation of SQL script's that can do the following:

• copy the table schema
• any constraints (identity, default values, etc)
• data within the table
• and many other options if needed

Good example workflow for SQL Server 2008 with screen shots shown here.

From Increase MySQL connection limit:-

MySQL’s default configuration sets the maximum simultaneous connections to 100. If you need to increase it, you can do it fairly easily:

For MySQL 3.x:

# vi /etc/my.cnf
set-variable = max_connections = 250

For MySQL 4.x and 5.x:

# vi /etc/my.cnf
max_connections = 250

Restart MySQL once you’ve made the changes and verify with:

echo "show variables like 'max_connections';" | mysql

EDIT:-(From comments)

The maximum concurrent connection can be maximum range: 4,294,967,295. Check MYSQL docs

In case you are trying to use ARC app from google and post a XML and you are getting this error, then try changing the body content type to application/xml. Example here

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

Use the WScript.Shell instead, because it has a waitOnReturn option:

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "C:\folder\runbat.bat", windowStyle, waitOnReturn

(Idea copied from Wait for Shell to finish, then format cells - synchronously execute a command)

As suggested by @Joel and @Mark Chorley in earlier comments:

${empty companies}

This checks for null and empty lists/collections/arrays. It doesn't get you the length but it satisfies the example in the OP. If you can get away with it this is just cleaner than importing a tag library and its crusty syntax like gt.

if your button is inside your form class:

buttonOk.Click += new EventHandler(your_click_method);

(might not be exactly EventHandler)

and in your click method:

this.Close();

If you need to show a message box:

MessageBox.Show("test");
