SQL Server has no setting to control query timeout in the connection string, and as far as I know this is the same for other major databases. But, this doesn't look like the problem you're seeing: I'd expect to see an exception raised
Error: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
if there genuinely was a timeout executing the query.
If this does turn out to be a problem, you can change the default timeout for a SQL Server database as a property of the database itself; use SQL Server Manager for this.
Be sure that the query is exactly the same from your Web application as the one you're running directly. Use a profiler to verify this.
You might get the error with the latest android gradle plugin (3.0):
Cannot set the value of read-only property 'outputFile'
According to the migration guide, we should use the following approach now:
applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "${applicationName}_${variant.buildType.name}_${defaultConfig.versionName}.apk"
}
}
Note 2 main changes here:
all is used now instead of each to iterate over the variant outputs.outputFileName property is used instead of mutating a file reference.$var = mysql_real_escape_string("data & the base");
$result = mysql_query('SELECT * FROM php_bugs WHERE php_bugs_category like "%' .$var.'%"');
I usually do what Josh recommended, but brainstormed and tested a slightly hokey alternative that I felt like sharing.
You can take advantage of the fact that COUNT(ColumnName) doesn't count NULLs, and use something like this:
SELECT COUNT(NULLIF(0, myColumn))
FROM AD_CurrentView
NULLIF - returns NULL if the two passed in values are the same.
Advantage: Expresses your intent to COUNT rows instead of having the SUM() notation. Disadvantage: Not as clear how it is working ("magic" is usually bad).
For Decryption:
def decrypt(my_key=KEY, my_iv=IV, encryptText=encrypttext):
key = binascii.unhexlify(my_key)
iv = binascii.unhexlify(my_iv)
encryptor = AES.new(key, AES.MODE_CBC, iv, segment_size=128) # Initialize encryptor
result = encryptor.decrypt(binascii.a2b_hex(encryptText))
padder = PKCS7Padder()
decryptText=padder.decode(result)
return {
"plain": encryptText,
"key": binascii.hexlify(key),
"iv": binascii.hexlify(iv),
"decryptedTest": decryptText
}
You will want to use the YYYYMMDD for unambiguous date determination in SQL Server.
insert into table1(approvaldate)values('20120618 10:34:09 AM');
If you are married to the dd-mm-yy hh:mm:ss xm format, you will need to use CONVERT with the specific style.
insert into table1 (approvaldate)
values (convert(datetime,'18-06-12 10:34:09 PM',5));
5 here is the style for Italian dates. Well, not just Italians, but that's the culture it's attributed to in Books Online.
The Functional Java library has an array wrapper class that equips arrays with handy methods like concatenation.
import static fj.data.Array.array;
...and then
Array<String> both = array(first).append(array(second));
To get the unwrapped array back out, call
String[] s = both.array();
From the Solution Explorer window select your form, right-click, click on View Designer. Voila! The form should display.
I tried posting a couple screenshots, but this is my first post; therefore, I could not post any images.
You are halfway there. Try:
In [4]: a[a < 0] = 0
In [5]: a
Out[5]: array([1, 2, 3, 0, 5])
It sounds like you want a StackPanel where the final element uses up all the remaining space. But why not use a DockPanel? Decorate the other elements in the DockPanel with DockPanel.Dock="Top", and then your help control can fill the remaining space.
XAML:
<DockPanel Width="200" Height="200" Background="PowderBlue">
<TextBlock DockPanel.Dock="Top">Something</TextBlock>
<TextBlock DockPanel.Dock="Top">Something else</TextBlock>
<DockPanel
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Height="Auto"
Margin="10">
<GroupBox
DockPanel.Dock="Right"
Header="Help"
Width="100"
Background="Beige"
VerticalAlignment="Stretch"
VerticalContentAlignment="Stretch"
Height="Auto">
<TextBlock Text="This is the help that is available on the news screen."
TextWrapping="Wrap" />
</GroupBox>
<StackPanel DockPanel.Dock="Left" Margin="10"
Width="Auto" HorizontalAlignment="Stretch">
<TextBlock Text="Here is the news that should wrap around."
TextWrapping="Wrap"/>
</StackPanel>
</DockPanel>
</DockPanel>
If you are on a platform without DockPanel available (e.g. WindowsStore), you can create the same effect with a grid. Here's the above example accomplished using grids instead:
<Grid Width="200" Height="200" Background="PowderBlue">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0">
<TextBlock>Something</TextBlock>
<TextBlock>Something else</TextBlock>
</StackPanel>
<Grid Height="Auto" Grid.Row="1" Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<GroupBox
Width="100"
Height="Auto"
Grid.Column="1"
Background="Beige"
Header="Help">
<TextBlock Text="This is the help that is available on the news screen."
TextWrapping="Wrap"/>
</GroupBox>
<StackPanel Width="Auto" Margin="10" DockPanel.Dock="Left">
<TextBlock Text="Here is the news that should wrap around."
TextWrapping="Wrap"/>
</StackPanel>
</Grid>
</Grid>
Use:
byte[] data = Base64.encode(base64str);
Encoding converts to Base64
You would need to reference commons codec from your project in order for that code to work.
For java8:

There's hardly any Swift-specific standard library yet; just the lean basic numeric, string, and collection types.
It's perfectly possible to define such shorthands using extensions, but as far as the actual out-of-the-box APIs goes, there is no "new" Cocoa; Swift just maps directly to the same old verbose Cocoa APIs as they already exist.
I'm sure neither of these options were available in C# when you asked the question but nowadays you can do it like the following:
// Return with ternary conditional operator.
private bool CheckAll()
{
return (your_condition) ? true : false;
}
// Alternatively as an expression bodied method.
private bool CheckAll() => (your_condition) ? true : false;
Investigating persistent sessions myself I have found that it's simply not worth the security risk. Use it if you absolutely have to, but you should consider such a session only weakly authenticated and force a new login for anything that could be of value to an attacker.
The reason being of course is that your cookies containing your persistent session are so easily stolen.
4 ways to steal your cookies (from a comment by Jens Roland on the page @splattne based his answer on):
Use "target" attribute and remove the 'compiler' attribute. See here. So it should go something like this:
<target name="compile">
<javac target="1.5" srcdir=.../>
</target>
Hope this helps
Chrome Extensions don't allow you to have inline JavaScript (documentation).
The same goes for Firefox WebExtensions (documentation).
You are going to have to do something similar to this:
Assign an ID to the link (<a onClick=hellYeah("xxx")> becomes <a id="link">), and use addEventListener to bind the event. Put the following in your popup.js file:
document.addEventListener('DOMContentLoaded', function() {
var link = document.getElementById('link');
// onClick's logic below:
link.addEventListener('click', function() {
hellYeah('xxx');
});
});
popup.js should be loaded as a separate script file:
<script src="popup.js"></script>
You could also use:
import time
start = time.clock()
do_something()
end = time.clock()
print "%.2gs" % (end-start)
Or you could use the python profilers.
Dim row As DataRow
For Each row In dtDataTable.Rows
Dim strDetail As String
strDetail = row("Detail")
Console.WriteLine("Processing Detail {0}", strDetail)
Next row
With HTML5 specification you do not need to write too much JS for the same or find some hacks.
One of the feature introduced in HTML5 is Web Workers which is JavaScript running in the background,independently of other scripts, without affecting the performance of the page.
It is supported in almost all browsers :
Chrome - 4.0+
IE - 10.0+
Mozilla - 3.5+
Safari - 4.0+
Opera - 11.5+
If, as I just encountered, you happen to have a jar file listed in the Project Structures->Libraries that is not in your classpath, the correct answer can be found by following the link given by @CrazyCoder above: Look here http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html
This says that to add the jar file as a module dependency within the Project Structure dialog:
For a single string String.ToCharArray should be used
string str = "One";
var charArray = str.ToCharArray();
For an array of strings
string[] arrayStrings = { "One", "Two", "Three" };
var charArrayList = arrayStrings.Select(str => str.ToCharArray()).ToList();
For a single character from a single string:
string str = "One";
var ch = str[0]; // means 'O'
Try this, assuming you're on Spring 3.1:
<beans xmlns="http://www.springframework.org/schema/beans"

xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
Replace 3.1 on the last line with whatever major Spring version you use. Meaning: there is no 3.1.1 XSD even though there is a Spring version 3.1.1.
Try the following (note that there should not be a space between the VAR, =, and GREG).

If it helps anyone, I tried everything above (https w/token mode) - and still nothing was working. I got no errors, but nothing would be installed in node_modules or package_lock.json. If I changed the token or any letter in the repo name or user name, etc. - I'd get an error. So I knew I had the right token and repo name.
I finally realized it's because the name of the dependency I had in my package.json didn't match the name in the package.json of the repo I was trying to pull. Even npm install --verbose doesn't say there's any problem. It just seems to ignore the dependency w/o error.
You can use
<?php
{
AddLog("anypage.php","reason",ERR_ERROR);

?>
or if you want to print that statement in an log you can use
AddLog("anypage.php","string: ".$string,ERR_DEBUG_LOW);
It seems to work if you use
div#scrollable {
overflow-y: scroll;
height: 100%;
}
and add padding-bottom: 60px to div.sidebar.
For example: http://jsfiddle.net/AKL35/6/
However, I am unsure why it must be 60px.
Also, you missed the f from overflow-y: scroll;
I would recommend setting the HR itself to be 0px high and use its border to be visible instead. I have noticed that when you zoom in and out (ctrl + mouse wheel) the thickness of HR itself changes, while when you set the border it always stays the same:
hr {
height: 0px;
border: none;
border-top: 1px solid black;
}
C++ supplies a string class that can be used like this:
#include <string>
#include <iostream>
int main() {
std::string Something = "Some text";
std::cout << Something << std::endl;
}
While it's possible to abort a thread, in practice it's almost always a very bad idea to do so. Aborthing a thread means the thread is not given a chance to clean up after itself, leaving resources undeleted, and things in unknown states.
In practice, if you abort a thread, you should only do so in conjunction with killing the process. Sadly, all too many people think ThreadAbort is a viable way of stopping something and continuing on, it's not.
Since Tasks run as threads, you can call ThreadAbort on them, but as with generic threads you almost never want to do this, except as a last resort.
This can now be achieved by simply setting the domain to none.
ga('create', 'UA-XXXX-Y', 'none');

The easiest way would be to drop the tablespace then build the tablespace back up. But I'd rather not have to do that. This is similar to Henry's except that I just do a copy/paste on the resultset in my gui.

Some answers does not explain the side effects of variations in the timezone for JavaScript Date object. So you should consider this answer if this is a concern for you.
Method 1: Machine's timezone dependent
By default, JavaScript returns a Date considering the machine's timezone, so getTime() result varies from computer to computer. You can check this behavior running:
new Date(1970, 0, 1, 0, 0, 0, 0).getTime()
// Since 1970-01-01 is Epoch, you may expect ZERO
// but in fact the result varies based on computer's timezone
This is not a problem if you really want the time since Epoch considering your timezone. So if you want to get time since Epoch for the current Date or even a specified Date based on the computer's timezone, you're free to continue using this method.
// Seconds since Epoch (Unix timestamp format)
new Date().getTime() / 1000 // local Date/Time since Epoch in seconds
new Date(2020, 11, 1).getTime() / 1000 // time since Epoch to 2020-12-01 00:00 (local timezone) in seconds
// Milliseconds since Epoch (used by some systems, eg. JavaScript itself)
new Date().getTime() // local Date/Time since Epoch in milliseconds
new Date(2020, 0, 2).getTime() // time since Epoch to 2020-01-02 00:00 (local timezone) in milliseconds
// **Warning**: notice that MONTHS in JavaScript Dates starts in zero (0 = January, 11 = December)
Method 2: Machine's timezone independent
However, if you want to get ride of variations in timezone and get time since Epoch for a specified Date in UTC (that is, timezone independent), you need to use Date.UTC method or shift the date from your timezone to UTC:
Date.UTC(1970, 0, 1)
// should be ZERO in any computer, since it is ZERO the difference from Epoch
// Alternatively (if, for some reason, you do not want Date.UTC)
const timezone_diff = new Date(1970, 0, 1).getTime() // difference in milliseconds between your timezone and UTC
(new Date(1970, 0, 1).getTime() - timezone_diff)
// should be ZERO in any computer, since it is ZERO the difference from Epoch
So, using this method (or, alternatively, subtracting the difference), the result should be:
// Seconds since Epoch (Unix timestamp format)
Date.UTC(2020, 0, 1) / 1000 // time since Epoch to 2020-01-01 00:00 UTC in seconds
// Alternatively (if, for some reason, you do not want Date.UTC)
const timezone_diff = new Date(1970, 0, 1).getTime()
(new Date(2020, 0, 1).getTime() - timezone_diff) / 1000 // time since Epoch to 2020-01-01 00:00 UTC in seconds
(new Date(2020, 11, 1).getTime() - timezone_diff) / 1000 // time since Epoch to 2020-12-01 00:00 UTC in seconds
// Milliseconds since Epoch (used by some systems, eg. JavaScript itself)
Date.UTC(2020, 0, 2) // time since Epoch to 2020-01-02 00:00 UTC in milliseconds
// Alternatively (if, for some reason, you do not want Date.UTC)
const timezone_diff = new Date(1970, 0, 1).getTime()
(new Date(2020, 0, 2).getTime() - timezone_diff) // time since Epoch to 2020-01-02 00:00 UTC in milliseconds
// **Warning**: notice that MONTHS in JavaScript Dates starts in zero (0 = January, 11 = December)
IMO, unless you know what you're doing (see note above), you should prefer Method 2, since it is machine independent.
End note
Although the recomendations in this answer, and since Date.UTC does not work without a specified date/time, you may be inclined in using the alternative approach and doing something like this:
const timezone_diff = new Date(1970, 0, 1).getTime()
(new Date().getTime() - timezone_diff) // <-- !!! new Date() without arguments
// means "local Date/Time subtracted by timezone since Epoch" (?)
This does not make any sense and it is probably WRONG (you are modifying the date). Be aware of not doing this. If you want to get time since Epoch from the current date AND TIME, you are most probably OK using Method 1.

If the "default value" you want is immutable, @eduffy's suggestion, e.g. [0]*10, is good enough.
But if you want, say, a list of ten dicts, do not use [{}]*10 -- that would give you a list with the same initially-empty dict ten times, not ten distinct ones. Rather, use [{} for i in range(10)] or similar constructs, to construct ten separate dicts to make up your list.
I know this question has already been answered, but another option is simply to open the destination and source folders in Finder and then drag and drop them into the terminal. The paths will automatically be copied and properly formatted (thus negating the need to actually figure out proper file names/extensions).
I have to do over-network copies between Mac and Windows machines, sometimes fairly deep down in filetrees, and have found this the most effective way to do so.
So, as an example:
cp -r [drag and drop source folder from finder] [drag and drop destination folder from finder]

<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
</customHeaders>
</httpProtocol>

Mozilla Developer Network has a nice description and example of onbeforeunload.
If you want to warn the user before leaving the page if your page is dirty (i.e. if user has entered some data):
window.addEventListener('beforeunload', function(e) {
var myPageIsDirty = ...; //you implement this logic...
if(myPageIsDirty) {
//following two lines will cause the browser to ask the user if they
//want to leave. The text of this dialog is controlled by the browser.
e.preventDefault(); //per the standard
e.returnValue = ''; //required for Chrome
}
//else: user is allowed to leave without a warning dialog
});

? extends HasWord
means "A class/interface that extends HasWord." In other words, HasWord itself or any of its children... basically anything that would work with instanceof HasWord plus null.
In more technical terms, ? extends HasWord is a bounded wildcard, covered in Item 31 of Effective Java 3rd Edition, starting on page 139. The same chapter from the 2nd Edition is available online as a PDF; the part on bounded wildcards is Item 28 starting on page 134.
Update: PDF link was updated since Oracle removed it a while back. It now points to the copy hosted by the Queen Mary University of London's School of Electronic Engineering and Computer Science.
Update 2: Lets go into a bit more detail as to why you'd want to use wildcards.
If you declare a method whose signature expect you to pass in List<HasWord>, then the only thing you can pass in is a List<HasWord>.
However, if said signature was List<? extends HasWord> then you could pass in a List<ChildOfHasWord> instead.
Note that there is a subtle difference between List<? extends HasWord> and List<? super HasWord>. As Joshua Bloch put it: PECS = producer-extends, consumer-super.
What this means is that if you are passing in a collection that your method pulls data out from (i.e. the collection is producing elements for your method to use), you should use extends. If you're passing in a collection that your method adds data to (i.e. the collection is consuming elements your method creates), it should use super.
This may sound confusing. However, you can see it in List's sort command (which is just a shortcut to the two-arg version of Collections.sort). Instead of taking a Comparator<T>, it actually takes a Comparator<? super T>. In this case, the Comparator is consuming the elements of the List in order to reorder the List itself.
"return" does exit the function but if you want to return large sums of data, you can store it in an array and then return it instead of trying to returning each piece of data 1 by 1 in the loop.
You can do this in one line and one go:
df.drop([col for col in df.columns if "Unnamed" in col], axis=1, inplace=True)
This involves less moving around/copying of the object than the solutions above.
This is a variable jQuery uses internally, but had no reason to hide, so it's there to use. Just a heads up, it becomes jquery.ajax.active next release. There's no documentation because it's exposed but not in the official API, lots of things are like this actually, like jQuery.cache (where all of jQuery.data() goes).
I'm guessing here by actual usage in the library, it seems to be there exclusively to support $.ajaxStart() and $.ajaxStop() (which I'll explain further), but they only care if it's 0 or not when a request starts or stops. But, since there's no reason to hide it, it's exposed to you can see the actual number of simultaneous AJAX requests currently going on.
When jQuery starts an AJAX request, this happens:
if ( s.global && ! jQuery.active++ ) {
jQuery.event.trigger( "ajaxStart" );
}
This is what causes the $.ajaxStart() event to fire, the number of connections just went from 0 to 1 (jQuery.active++ isn't 0 after this one, and !0 == true), this means the first of the current simultaneous requests started. The same thing happens at the other end. When an AJAX request stops (because of a beforeSend abort via return false or an ajax call complete function runs):
if ( s.global && ! --jQuery.active ) {
jQuery.event.trigger( "ajaxStop" );
}
This is what causes the $.ajaxStop() event to fire, the number of requests went down to 0, meaning the last simultaneous AJAX call finished. The other global AJAX handlers fire in there along the way as well.
C90 does not support the boolean data type.
C99 does include it with this include:

Alternative and much easier way is to use shapes instead of 9-patches. It is already explained here: https://stackoverflow.com/a/24725831/512011
A late answer, but here is an alternative to the SCOPE_IDENTITY() answers that we ended up using: OUTPUT INSERTED
Return only ID of inserted object:
It allows you to get all or some attributes of the inserted row:
string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
OUTPUT INSERTED.[Id]
VALUES(@Username, @Phone, @Email);";
int newUserId = conn.QuerySingle<int>(
insertUserSql,
new
{
Username = "lorem ipsum",
Phone = "555-123",
Email = "lorem ipsum"
},
tran);
Return inserted object with ID:
If you wanted you could get Phone and Email or even the whole inserted row:
string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
OUTPUT INSERTED.*
VALUES(@Username, @Phone, @Email);";
User newUser = conn.QuerySingle<User>(
insertUserSql,
new
{
Username = "lorem ipsum",
Phone = "555-123",
Email = "lorem ipsum"
},
tran);
Also, with this you can return data of deleted or updated rows. Just be careful if you are using triggers because (from link mentioned before):
Columns returned from OUTPUT reflect the data as it is after the INSERT, UPDATE, or DELETE statement has completed but before triggers are executed.
For INSTEAD OF triggers, the returned results are generated as if the INSERT, UPDATE, or DELETE had actually occurred, even if no modifications take place as the result of the trigger operation. If a statement that includes an OUTPUT clause is used inside the body of a trigger, table aliases must be used to reference the trigger inserted and deleted tables to avoid duplicating column references with the INSERTED and DELETED tables associated with OUTPUT.

A agree with the methods mentioned by maxnk, however you may want to reconsider trying to automatically force the browser to download the URL. It may work fine for binary files but for other types of files (text, PDF, images, video), the browser may want to render it in the window (or IFRAME) rather than saving to disk.
If you really do need to make an Ajax call to get the final download links, what about using DHTML to dynamically write out the download link (from the ajax response) into the page? That way the user could either click on it to download (if binary) or view in their browser - or select "Save As" on the link to save to disk. It's an extra click, but the user has more control.

I know this is an old post, but there is a FAR simpler answer (though maybe it only works in newer versions of windows). Just use the /t parameter for the DATE and TIME dos commands to only show the date or time and not prompt you to set it, like this:
@echo off
echo Starting test batch file > testlog.txt
date /t >> testlog.txt
time /t >> testlog.txt

This will allow you to update a table based on the column value not being found in another table.
UPDATE table1 SET table1.column = 'some_new_val' WHERE table1.id IN (
SELECT *
FROM (
SELECT table1.id
FROM table1
LEFT JOIN table2 ON ( table2.column = table1.column )
WHERE table1.column = 'some_expected_val'
AND table12.column IS NULL
) AS Xalias
)
This will update a table based on the column value being found in both tables.
UPDATE table1 SET table1.column = 'some_new_val' WHERE table1.id IN (
SELECT *
FROM (
SELECT table1.id
FROM table1
JOIN table2 ON ( table2.column = table1.column )
WHERE table1.column = 'some_expected_val'
) AS Xalias
)
As Bergi noticed, I think the best and clear solution is use BlueBird.each, code below:
const BlueBird = require('bluebird');
BlueBird.each(files, fs.readFileAsync);
Setup twig
$twig = new Twig_Environment(...);
$twig->addGlobal('session', $_SESSION);
Then within your template access session values for example
$_SESSION['username'] in php file Will be equivalent to {{ session.username }} in your twig template
DELETE
FROM m_productprice B
USING m_product C
WHERE B.m_product_id = C.m_product_id AND
C.upc = '7094' AND
B.m_pricelist_version_id='1000020';
or
DELETE
FROM m_productprice
WHERE m_pricelist_version_id='1000020' AND
m_product_id IN (SELECT m_product_id
FROM m_product
WHERE upc = '7094');
It's generally a bad idea to write your own cryptography unless you have experience breaking other peoples' cryptography implementations.
None of the examples here authenticate the ciphertext, which leaves them vulnerable to bit-rewriting attacks.
<?php
// PECL libsodium 0.2.1 and newer
/**
* Encrypt a message
*
* @param string $message - message to encrypt
* @param string $key - encryption key
* @return string
*/
function safeEncrypt($message, $key)
{
$nonce = \Sodium\randombytes_buf(
\Sodium\CRYPTO_SECRETBOX_NONCEBYTES
);
return base64_encode(
$nonce.
\Sodium\crypto_secretbox(
$message,
$nonce,
$key
)
);
}
/**
* Decrypt a message
*
* @param string $encrypted - message encrypted with safeEncrypt()
* @param string $key - encryption key
* @return string
*/
function safeDecrypt($encrypted, $key)
{
$decoded = base64_decode($encrypted);
$nonce = mb_substr($decoded, 0, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
$ciphertext = mb_substr($decoded, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');
return \Sodium\crypto_secretbox_open(
$ciphertext,
$nonce,
$key
);
}
Then to test it out:
<?php
// This refers to the previous code block.
require "safeCrypto.php";
// Do this once then store it somehow:
$key = \Sodium\randombytes_buf(\Sodium\CRYPTO_SECRETBOX_KEYBYTES);
$message = 'We are all living in a yellow submarine';
$ciphertext = safeEncrypt($message, $key);
$plaintext = safeDecrypt($ciphertext, $key);
var_dump($ciphertext);
var_dump($plaintext);
This can be used in any situation where you are passing data to the client (e.g. encrypted cookies for sessions without server-side storage, encrypted URL parameters, etc.) with a reasonably high degree of certainty that the end user cannot decipher or reliably tamper with it.
Since libsodium is cross-platform, this also makes it easier to communicate with PHP from, e.g. Java applets or native mobile apps.
Note: If you specifically need to add encrypted cookies powered by libsodium to your app, my employer Paragon Initiative Enterprises is developing a library called Halite that does all of this for you.
You shouldn't be using onClick any more if you are using jQuery. jQuery provides its own methods of attaching and binding events. See .click()
$(document).ready(function(){
var js = "alert('B:' + this.id); return false;";
// create a function from the "js" string
var newclick = new Function(js);
// clears onclick then sets click using jQuery
$("#anchor").attr('onclick', '').click(newclick);
});
That should cancel the onClick function - and keep your "javascript from a string" as well.
The best thing to do would be to remove the onclick="" from the <a> element in the HTML code and switch to using the Unobtrusive method of binding an event to click.
You also said:
Using
onclick = function() { return eval(js); }doesn't work because you are not allowed to use return in code passed to eval().
No - it won't, but onclick = eval("(function(){"+js+"})"); will wrap the 'js' variable in a function enclosure. onclick = new Function(js); works as well and is a little cleaner to read. (note the capital F) -- see documentation on Function() constructors
And for those of you using an anonymous expression:
await Task.Run(async () =>
{
SQLLiteUtils slu = new SQLiteUtils();
await slu.DeleteGroupAsync(groupname);
});
The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.
Thank you all for your help!
I recently started playing with MQTT http://mqtt.org for Android as a way of doing what you're asking for (i.e. not SMS but data driven, almost immediate message delivery, scalable, not polling, etc.)
I have a blog post with background information on this in case it's helpful http://dalelane.co.uk/blog/?p=938
(Note: MQTT is an IBM technology, and I should point out that I work for IBM.)
You can also get an EntityManager using PersistenceContext or Autowired annotation, but be aware that it will not be thread-safe.

A solution that worked great for me - edit locally on Mac, and have the file automatically synchronized to a remote machine
Make sure you have passwordless login to the remote machine. If not, follow these steps http://osxdaily.com/2012/05/25/how-to-set-up-a-password-less-ssh-login/
create a file in ~/Library/LaunchAgents/filesynchronizer.plist, with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>filesynchronizer</string>
<key>ProgramArguments</key>
<array>
<string>/usr/bin/rsync</string>
<string>-avz</string>
<string>/Users/USERNAME/SyncDirectory</string>
<string>USERNAME@REMOTEMACHINE:~</string>
</array>
<key>WatchPaths</key>
<array>
<string>/Users/USERNAME/SyncDirectory</string>
</array>
</dict>
</plist>
In a terminal window run
launchctl load ~/Library/LaunchAgents/filesynchronizer.plist
That's it. Any changes to any files in ~/SyncDirectory will be synchronized to ~/SyncDirectory on the remote machine. Local changes will override any remote changes.
This creates a launchd job that monitors SyncDirectory, and whenever anything changes there runs rsync to synchronize the directory to the remote machine.
Just for completeness: you may also use array_walk:
array_walk($yourArray, function(&$value)
{
$value = strtolower($value);
});
From PHP docs:
If callback needs to be working with the actual values of the array, specify the first parameter of callback as a reference. Then, any changes made to those elements will be made in the original array itself.
Or directly via foreach loop using references:
foreach($yourArray as &$value)
$value = strtolower($value);
Note that these two methods change the array "in place", whereas array_map creates and returns a copy of the array, which may not be desirable in case of very large arrays.
There is a simpler way simply disable the error handler in your error handler if it does not match the error types you are doing and resume.
The handler below checks agains each error type and if none are a match it returns error resume to normal VBA ie GoTo 0 and resumes the code which then tries to rerun the code and the normal error block pops up.
On Error GoTo ErrorHandler
x = 1/0
ErrorHandler:
if Err.Number = 13 then ' 13 is Type mismatch (only used as an example)
'error handling code for this
end if
If err.Number = 1004 then ' 1004 is Too Large (only used as an example)
'error handling code for this
end if
On Error GoTo 0
Resume
Have you checked this http://docs.python.org/2/install/ ?
First you have to install the module
$ pip install requests
Then, before using it you must import it from your program.
from requests import requests
Note that your modules must be in the same directory.
Then you can use it.
For this part you have to check for the documentation.
JSON (= JavaScript Object Notation), is a lightweight and fast mechanism to convert Javascript objects into a string and vice versa.
Since Javascripts objects consists of key/value pairs its very easy to use and access JSON that way.
So if we have an object:
var myObj = {
foo: 'bar',
base: 'ball',
deep: {
java: 'script'
}
};
We can convert that into a string by calling window.JSON.stringify(myObj); with the result of "{"foo":"bar","base":"ball","deep":{"java":"script"}}".
The other way around, we would call window.JSON.parse("a json string like the above");.
JSON.parse() returns a javascript object/array on success.
alert(myObj.deep.java); // 'script'
window.JSON is not natively available in all browser. Some "older" browser need a little javascript plugin which offers the above mentioned functionality. Check http://www.json.org for further information.
Are you looking for actual infinity or the minimal finite value? If the former, use
-numeric_limits<double>::infinity()
which only works if
numeric_limits<double>::has_infinity
Otherwise, you should use
numeric_limits<double>::lowest()
which was introduces in C++11.
If lowest() is not available, you can fall back to
-numeric_limits<double>::max()
which may differ from lowest() in principle, but normally doesn't in practice.
Try using display() function. This would automatically use Horizontal and vertical scroll bars and with this you can display different datasets easily instead of using print().
display(dataframe)
display() supports proper alignment also.
However if you want to make the dataset more beautiful you can check pd.option_context(). It has lot of options to clearly show the dataframe.
Note - I am using Jupyter Notebooks.
Hope this will assist anyone having the same error while importing CSV data into related tables. In my case the parent table was OK, but I got the error while importing data to the child table containing the foreign key. After temporarily removing the foregn key constraint on the child table, I managed to import the data and was suprised to find some of the values in the FK column having values of 0 (obviously this had been causing the error since the parent table did not have such values in its PK column). The cause was that, the data in my CSV column preceeding the FK column contained commas (which I was using as a field delimeter). Changing the delimeter for my CSV file solved the problem.
Preview in OS X seems to be able to do this out of the box. Adobe Reader shows the doc as "data typed can't be saved" but Preview was able to save my changes without hassle.
I know this is very late to the game ... but this always works for me:
ssh-add ~/.ssh/KEY_PAIR_NAME.pem
ssh user_name@<instance public dns/ip>
e.g.
ssh [email protected]
hope this helps someone.
from cmd run: SVN List URL you will be provided with 3 options (r)eject, (a)ccept, (p)ermanently. enter p. This resolved issue for me
You can make a symbolic link of your module to the standard path, so depmod will see it and you'll be able load it as any other module.
sudo ln -s /path/to/module.ko /lib/modules/`uname -r`
sudo depmod -a
sudo modprobe module
If you add the module name to /etc/modules it will be loaded any time you boot.
Anyway I think that the proper configuration is to copy the module to the standard paths.

You can use the function last_insert_rowid():
The
last_insert_rowid()function returns theROWIDof the last row insert from the database connection which invoked the function. Thelast_insert_rowid()SQL function is a wrapper around thesqlite3_last_insert_rowid()C/C++ interface function.
Instead of refreshing manually you should use observeable properties. The answers of this question examples the purpose: SimpleStringProperty and SimpleIntegerProperty TableView JavaFX
XPath 1.0 doesn't handle regex natively, you could try something like
//*[starts-with(@id, 'sometext') and ends-with(@id, '_text')]
(as pointed out by paul t, //*[boolean(number(substring-before(substring-after(@id, "sometext"), "_text")))] could be used to perform the same check your original regex does, if you need to check for middle digits as well)
In XPath 2.0, try
//*[matches(@id, 'sometext\d+_text')]
There is no command based text editors in windows (at least from Windows 7). But you can try the vi windows clone available here : http://www.vim.org/

Any comment?
The short version is that you cannot use variable-width patterns in lookbehinds using Python's re module. There is no way to change this:
>>> import re
>>> re.sub("(?<=foo)bar(?=baz)", "quux", "foobarbaz")
'fooquuxbaz'
>>> re.sub("(?<=fo+)bar(?=baz)", "quux", "foobarbaz")
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
re.sub("(?<=fo+)bar(?=baz)", "quux", string)
File "C:\Development\Python25\lib\re.py", line 150, in sub
return _compile(pattern, 0).sub(repl, string, count)
File "C:\Development\Python25\lib\re.py", line 241, in _compile
raise error, v # invalid expression
error: look-behind requires fixed-width pattern
This means that you'll need to work around it, the simplest solution being very similar to what you're doing now:
>>> re.sub("(fo+)bar(?=baz)", "\\1quux", "foobarbaz")
'fooquuxbaz'
>>>
>>> # If you need to turn this into a callable function:
>>> def replace(start, replace, end, replacement, search):
return re.sub("(" + re.escape(start) + ")" + re.escape(replace) + "(?=" + re.escape + ")", "\\1" + re.escape(replacement), search)
This doesn't have the elegance of the lookbehind solution, but it's still a very clear, straightforward one-liner. And if you look at what an expert has to say on the matter (he's talking about JavaScript, which lacks lookbehinds entirely, but many of the principles are the same), you'll see that his simplest solution looks a lot like this one.
I'd like to present a compact solution using a call by reference (yes, "batch" has pointers too!) to a function, and a "subfunction":
@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET /p NAME=- NAME ?
ECHO "%NAME%"
CALL :TRIM NAME
ECHO "%NAME%"
GOTO :EOF
:TRIM
SetLocal EnableDelayedExpansion
Call :TRIMSUB %%%1%%
EndLocal & set %1=%tempvar%
GOTO :EOF
:TRIMSUB
set tempvar=%*
GOTO :EOF
When I've run into similar situations, I generally avoid the package manager, especially if it would be embarrassing to break something, i.e. a production server. Instead, I would go to Activestate and download their binary package:
https://www.activestate.com/activepython/downloads/
This is installed by running a script which places everything into a folder and does not touch any system files. In fact, you don't even need root permissions to set it up. Then I change the name of the binary to something like apy26, add that folder to the end of the PATH and start coding. If you install packages with apy26 setup.py installor if you use virtualenv and easyinstall, then you have just as flexible a python environment as you need without touching the system standard python.
Edits... Recently I've done some work to build a portable Python binary for Linux that should run on any distro with no external dependencies. This means that any binary shared libraries needed by the portable Python module are part of the build, included in the tarball and installed in Python's private directory structure. This way you can install Python for your application without interfering with the system installed Python.
My github site has a build script which has been thoroughly tested on Ubuntu Lucid 10.04 LTS both 32 and 64 bit installs. I've also built it on Debian Etch but that was a while ago and I can't guarantee that I haven't changed something. The easiest way to do this is you just put your choice of Ubuntu Lucid in a virtual machine, checkout the script with git clone git://github.com/wavetossed/pybuild.git and then run the script.
Once you have it built, use the tarball on any recent Linux distro. There is one little wrinkle with moving it to a directory other than /data1/packages/python272 which is that you have to run the included patchelf to set the interpreter path BEFORE you move the directory. This affects any binaries in /data1/packages/python272/bin
All of this is based on building with RUNPATH and copying the dependent shared libraries. Even though the script is in several files, it is effectively one long shell script arranged in the style of /etc/rc.d directories.
SELECT * FROM tablename
WHERE column IN
(select column from tablename
where column like 'M510%'
or column like 'M615%'
OR column like 'M515%'
or column like'M612%'
)
Restarting VS2012 should fix the problem.
I have had the same issue that I solved this way:
Instead of adding the meta to the current page header that caused the same error as you had:
Page.Header.Controls.Add(meta);
I used this instead:
Master.FindControl("YourHeadContentPlaceHolder").Controls.Add(meta);
and it works like a charm.
I think this should work:
String rank = card.substring(0,1);
String suit = card.substring(1);
String cards = "A23456789TJQKDHSCl";
String[] name = {"Ace","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten","Jack","Queen","King","Diamonds","Hearts","Spades","Clubs"};
String c ="";
for(int a = 0, b = 1; a<cards.length()-1; b=a+1, a++ )
{
if( rank.equals( cards.substring(a,b) ) )
{
c+=name[a];
}
}
System.out.println(c);
Beside other answers, I think the main reason to "why using Functional Interface other than directly with lambda expressions" can be related to nature of Java language which is Object Oriented.
The main attributes of Lambda expressions are: 1. They can be passed around 2. and they can executed in future in specific time (several times). Now to support this feature in languages, some other languages deal simply with this matter.
For instance in Java Script, a function (Anonymous function, or Function literals) can be addressed as a object. So, you can create them simply and also they can be assigned to a variable and so forth. For example:
var myFunction = function (...) {
...;
}
alert(myFunction(...));
or via ES6, you can use an arrow function.
const myFunction = ... => ...
Up to now, Java language designers have not accepted to handle mentioned features via these manner (functional programming techniques). They believe that Java language is Object Oriented and therefore they should solve this problem via Object Oriented techniques. They don't want to miss simplicity and consistency of Java language.
Therefore, they use interfaces, as when an object of an interface with just one method (I mean functional interface) is need you can replace it with a lambda expression. Such as:
ActionListener listener = event -> ...;
Not best answer but you can reuse an already created ca bundle using --cert option of pip, for instance:
pip install SQLAlchemy==1.1.15 --cert="C:\Users\myUser\certificates\my_ca-bundle.crt"
The MOST IMPORTANT THING I didn't understand for quite awhile is that the request MUST contain "callback=JSON_CALLBACK", because AngularJS modifies the request url, substituting a unique identifier for "JSON_CALLBACK". The server response must use the value of the 'callback' parameter instead of hard coding "JSON_CALLBACK":
JSON_CALLBACK(json_response); // wrong!
Since I was writing my own PHP server script, I thought I knew what function name it wanted and didn't need to pass "callback=JSON_CALLBACK" in the request. Big mistake!
AngularJS replaces "JSON_CALLBACK" in the request with a unique function name (like "callback=angular.callbacks._0"), and the server response must return that value:
angular.callbacks._0(json_response);
Yes, It is required to add libraries after the source files/objects files. This command will solve the problem:
gcc -static -L/usr/lib -I/usr/lib main.c -ltommath
Try File.basename
Returns the last component of the filename given in file_name, which must be formed using forward slashes (``/’’) regardless of the separator used on the local file system. If suffix is given and present at the end of file_name, it is removed.
File.basename("/home/gumby/work/ruby.rb") #=> "ruby.rb" File.basename("/home/gumby/work/ruby.rb", ".rb") #=> "ruby"
In your case:
File.basename("C:\\projects\\blah.dll", ".dll") #=> "blah"
Grep is not sufficient for this operation.
pcregrep which is found in most of the modern Linux systems can be used as
pcregrep -M 'abc.*(\n|.)*efg' test.txt
where -M, --multiline allow patterns to match more than one line
There is a newer pcre2grep also. Both are provided by the PCRE project.
pcre2grep is available for Mac OS X via Mac Ports as part of port pcre2:
% sudo port install pcre2
and via Homebrew as:
% brew install pcre
or for pcre2
% brew install pcre2
pcre2grep is also available on Linux (Ubuntu 18.04+)
$ sudo apt install pcre2-utils # PCRE2
$ sudo apt install pcregrep # Older PCRE
No, there isn't a decent solution for body type, unless you're willing to cater only to those with bleeding-edge browsers.
Microsoft has WEFT, their own proprietary font-embedding technology, but I haven't heard it talked about in years, and I know no one who uses it.
I get by with sIFR for display type (headlines, titles of blog posts, etc.) and using one of the less-worn-out web-safe fonts for body type (like Trebuchet MS). If you're bored with all the web-safe fonts, you're probably defining the term too narrowly — look at this matrix of stock fonts that ship with major OSes and chances are you'll be able to find a font cascade that will catch nearly all web users.
For instance: font-family: "Lucida Grande", "Verdana", sans-serif is a common font cascade; OS X comes with Lucida Grande, but those with Windows will get Verdana, a web-safe font with letters of similar size and shape to Lucida Grande. Linux users will also get Verdana if they've installed the web-safe fonts package that exists in most distros' package managers, or else they'll fall back to an ordinary sans-serif.
I don't think that other example is what you're looking for. If you're just updating one column from another column in the same table you should be able to use something like this.
update some_table set null_column = not_null_column where null_column is null
For those of you who would like to simulate the set_contents_from_string like boto2 methods, you can try
import boto3
from cStringIO import StringIO
s3c = boto3.client('s3')
contents = 'My string to save to S3 object'
target_bucket = 'hello-world.by.vor'
target_file = 'data/hello.txt'
fake_handle = StringIO(contents)
# notice if you do fake_handle.read() it reads like a file handle
s3c.put_object(Bucket=target_bucket, Key=target_file, Body=fake_handle.read())
For Python3:
In python3 both StringIO and cStringIO are gone. Use the StringIO import like:
from io import StringIO
To support both version:
try:
from StringIO import StringIO
except ImportError:
from io import StringIO
you can get the 'date' filter like this:
var today = $filter('date')(new Date(),'yyyy-MM-dd HH:mm:ss Z');
This will give you today's date in format you want.

See the code
In Oracle 12c and above, we have two types of databases:
If you want to create an user, you have two possibilities:
You can create a "container user" aka "common user".
Common users belong to CBDs as well as to current and future PDBs. It means they can perform operations in Container DBs or Pluggable DBs according to assigned privileges.
create user c##username identified by password;
You can create a "pluggable user" aka "local user".
Local users belong only to a single PDB. These users may be given administrative privileges, but only for that PDB inside which they exist. For that, you should connect to pluggable datable like that:
alter session set container = nameofyourpluggabledatabase;
and there, you can create user like usually:
create user username identified by password;
Don't forget to specify the tablespace(s) to use, it can be useful during import/export of your DBs. See this for more information about it https://docs.oracle.com/database/121/SQLRF/statements_8003.htm#SQLRF01503
Check the username credential used to login to the database. (persistence.xml ??). The problem mostly is, the username\password used to login to the database, does not have visiblity to the object (table_name in this case). ( try logging in to sql developer, using the same username\password available in your data source)
Though Dan Lowe's excellent answer very thoroughly answered the OP's question about the difference between PUT and PATCH, its answer to the question of why PATCH is not idempotent is not quite correct.
To show why PATCH isn't idempotent, it helps to start with the definition of idempotence (from Wikipedia):
The term idempotent is used more comprehensively to describe an operation that will produce the same results if executed once or multiple times [...] An idempotent function is one that has the property f(f(x)) = f(x) for any value x.
In more accessible language, an idempotent PATCH could be defined as: After PATCHing a resource with a patch document, all subsequent PATCH calls to the same resource with the same patch document will not change the resource.
Conversely, a non-idempotent operation is one where f(f(x)) != f(x), which for PATCH could be stated as: After PATCHing a resource with a patch document, subsequent PATCH calls to the same resource with the same patch document do change the resource.
To illustrate a non-idempotent PATCH, suppose there is a /users resource, and suppose that calling GET /users returns a list of users, currently:
[{ "id": 1, "username": "firstuser", "email": "[email protected]" }]
Rather than PATCHing /users/{id}, as in the OP's example, suppose the server allows PATCHing /users. Let's issue this PATCH request:
PATCH /users
[{ "op": "add", "username": "newuser", "email": "[email protected]" }]
Our patch document instructs the server to add a new user called newuser to the list of users. After calling this the first time, GET /users would return:
[{ "id": 1, "username": "firstuser", "email": "[email protected]" },
{ "id": 2, "username": "newuser", "email": "[email protected]" }]
Now, if we issue the exact same PATCH request as above, what happens? (For the sake of this example, let's assume that the /users resource allows duplicate usernames.) The "op" is "add", so a new user is added to the list, and a subsequent GET /users returns:
[{ "id": 1, "username": "firstuser", "email": "[email protected]" },
{ "id": 2, "username": "newuser", "email": "[email protected]" },
{ "id": 3, "username": "newuser", "email": "[email protected]" }]
The /users resource has changed again, even though we issued the exact same PATCH against the exact same endpoint. If our PATCH is f(x), f(f(x)) is not the same as f(x), and therefore, this particular PATCH is not idempotent.
Although PATCH isn't guaranteed to be idempotent, there's nothing in the PATCH specification to prevent you from making all PATCH operations on your particular server idempotent. RFC 5789 even anticipates advantages from idempotent PATCH requests:
A PATCH request can be issued in such a way as to be idempotent, which also helps prevent bad outcomes from collisions between two PATCH requests on the same resource in a similar time frame.
In Dan's example, his PATCH operation is, in fact, idempotent. In that example, the /users/1 entity changed between our PATCH requests, but not because of our PATCH requests; it was actually the Post Office's different patch document that caused the zip code to change. The Post Office's different PATCH is a different operation; if our PATCH is f(x), the Post Office's PATCH is g(x). Idempotence states that f(f(f(x))) = f(x), but makes no guarantes about f(g(f(x))).
Just some basic Methods for that (inspired from native2ascii tool):
/**
* Encode a String like äöü to \u00e4\u00f6\u00fc
*
* @param text
* @return
*/
public String native2ascii(String text) {
if (text == null)
return text;
StringBuilder sb = new StringBuilder();
for (char ch : text.toCharArray()) {
sb.append(native2ascii(ch));
}
return sb.toString();
}
/**
* Encode a Character like ä to \u00e4
*
* @param ch
* @return
*/
public String native2ascii(char ch) {
if (ch > '\u007f') {
StringBuilder sb = new StringBuilder();
// write \udddd
sb.append("\\u");
StringBuffer hex = new StringBuffer(Integer.toHexString(ch));
hex.reverse();
int length = 4 - hex.length();
for (int j = 0; j < length; j++) {
hex.append('0');
}
for (int j = 0; j < 4; j++) {
sb.append(hex.charAt(3 - j));
}
return sb.toString();
} else {
return Character.toString(ch);
}
}
android only use linux kernel, that means the GNU tool chain like gcc as are not implemented in android, so if you want run a linux app in android, you need recompile it with google's tool chain( NDK ).
In our case we were able to narrow the cause down to a number of views which had WITH SCHEMABINDING on them. Although this is supposed to improve performance it was resulting in an awful query plan (doing a single record update on a table which was being referenced by these views was taking nearly 2 seconds of elapsed time). Removing WITH SCHEMABINDING has meant all is running smoothly again and the "wait operation timed out" errors have gone.
Thanks for the help everyone!
Turns out that it was an iptable conflict. Two rules listing the port open (which resulted in a closed port).
However, one of the comments by aka and another by manu2013 were problems that I would have run into, if not for the conflict.
So! Always remember to edit the /etc/mongod.conf file and set your bind_ip = 0.0.0.0 in order to make connections externally.
Also, make sure that you don't have conflicting rules in your iptable for the port mongo wants (see link on mongodb's site to set up your iptables properly).
I don't like function_exists('fun_name') because it relies on the function name being turned into a string, plus, you have to name it twice. Could easily break with refactoring.
Declare your function as a lambda expression (I haven't seen this solution mentioned):
$generate_salt = function()
{
...
};
And use thusly:
$salt = $generate_salt();
Then, at re-execution of said PHP code, the function simply overwrites the previous declaration.
Add this to your class,
public class func showSettingsAlert(title:String,message:String,onVC viewController:UIViewController,onCancel:(()->())?){
YourClass.show2ButtonsAlert(onVC: viewController, title: title, message: message, button1Title: "Settings", button2Title: "Cancel", onButton1Click: {
if let settingsURL = NSURL(string: UIApplicationOpenSettingsURLString){
UIApplication.sharedApplication().openURL(settingsURL)
}
}, onButton2Click: {
onCancel?()
})
}
public class func show2ButtonsAlert(onVC viewController:UIViewController,title:String,message:String,button1Title:String,button2Title:String,onButton1Click:(()->())?,onButton2Click:(()->())?){
dispatch_async(dispatch_get_main_queue()) {
let alert : UIAlertController = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: button1Title, style:.Default, handler: { (action:UIAlertAction) in
onButton1Click?()
}))
alert.addAction(UIAlertAction(title: button2Title, style:.Default, handler: { (action:UIAlertAction) in
onButton2Click?()
}))
viewController.presentViewController(alert, animated: true, completion: nil)
}
}
Call like this,
YourClass.showSettingsAlert("App would like to access camera", message: "App would like to access camera desc", onVC: fromViewController, onCancel: {
print("canceled")
})
You could use .apply()
You need to specify a this... I guess you could use the this within mainfunc.
function mainfunc (func)
{
var args = new Array();
for (var i = 1; i < arguments.length; i++)
args.push(arguments[i]);
window[func].apply(this, args);
}
One other approach that we have taken successfully is to generate the WS client proxy code using wsimport (from Ant, as an Ant task) and specify the wsdlLocation attribute.
<wsimport debug="true" keep="true" verbose="false" target="2.1" sourcedestdir="${generated.client}" wsdl="${src}${wsdl.file}" wsdlLocation="${wsdl.file}">
</wsimport>
Since we run this for a project w/ multiple WSDLs, the script resolves the $(wsdl.file} value dynamically which is set up to be /META-INF/wsdl/YourWebServiceName.wsdl relative to the JavaSource location (or /src, depending on how you have your project set up). During the build proess, the WSDL and XSDs files are copied to this location and packaged in the JAR file. (similar to the solution described by Bhasakar above)
MyApp.jar
|__META-INF
|__wsdl
|__YourWebServiceName.wsdl
|__YourWebServiceName_schema1.xsd
|__YourWebServiceName_schmea2.xsd
Note: make sure the WSDL files are using relative refrerences to any imported XSDs and not http URLs:
<types>
<xsd:schema>
<xsd:import namespace="http://valueobject.common.services.xyz.com/" schemaLocation="YourWebService_schema1.xsd"/>
</xsd:schema>
<xsd:schema>
<xsd:import namespace="http://exceptions.util.xyz.com/" schemaLocation="YourWebService_schema2.xsd"/>
</xsd:schema>
</types>
In the generated code, we find this:
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2-b05-
* Generated source version: 2.1

*/
@WebServiceClient(name = "YourService", targetNamespace = "http://test.webservice.services.xyz.com/", wsdlLocation = "/META-INF/wsdl/YourService.wsdl")

e = new WebServiceException("Cannot find '/META-INF/wsdl/YourService.wsdl' wsdl. Place the resource correctly in the classpath.");
}
YOURWEBSERVICE_EXCEPTION = e;
}
public YourService_Service() {
super(__getWsdlLocation(), YOURWEBSERVICE_QNAME);
}

private static URL __getWsdlLocation() {
if (YOURWEBSERVICE_EXCEPTION!= null) {
throw YOURWEBSERVICE_EXCEPTION;
}
return YOURWEBSERVICE_WSDL_LOCATION;

Perhaps this might help too. It's just a different approach that does not use the "catalog" approach.
In the Table Designer on SQL Server Management Studio you can set the where the auto increment will start. Right-click on the table in Object Explorer and choose Design, then go to the Column Properties for the relevant column:
Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.
[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.
var http = require('http'),
fileSystem = require('fs'),
path = require('path');
http.createServer(function(request, response) {
var filePath = path.join(__dirname, 'myfile.mp3');
var stat = fileSystem.statSync(filePath);
response.writeHead(200, {
'Content-Type': 'audio/mpeg',
'Content-Length': stat.size
});
var readStream = fileSystem.createReadStream(filePath);
// We replaced all the event handlers with a simple call to readStream.pipe()
readStream.pipe(response);
})
.listen(2000);

One trick I found was putting your setOnItemSelectedListeners in onWindowFocusChanged instead of onCreate. I haven't found any bad side-effects to doing it this way, yet. Basically, set up the listeners after the window gets drawn. I'm not sure how often onWindowFocusChanged runs, but it's easy enough to create yourself a lock variable if you are finding it running too often.
I think Android might be using a message-based processing system, and if you put it all in onCreate, you may run into situations where the spinner gets populated after it gets drawn. So, your listener will fire off after you set the item location. This is an educated guess, of course, but feel free to correct me on this.
You might want to take a look at Joda Time which is a really good API for dealing with date/time. Even though if you don't really need it for the solution to your current question it is bound to save you pain in the future.
you can write the function in a separate file (say common-functions.php) and include it wherever needed.
function getEmployeeFullName($employeeId) {
// Write code to return full name based on $employeeId
}
You can include common-functions.php in another file as below.
include('common-functions.php');
echo 'Name of first employee is ' . getEmployeeFullName(1);
You can include any number of files to another file. But including comes with a little performance cost. Therefore include only the files which are really required.
@POST
@Path ("Employee")
@Consumes("application/json")
@Produces("application/json")
public JSONObject postEmployee(JSONObject jsonObject)throws Exception{
return jsonObject;
}
Notice that there is a difference between
set encoding
and
set fileencoding
In the first case, you'll change the output encoding that is shown in the terminal. In the second case, you'll change the output encoding of the file that is written.
Concatenating the columns together in some form is a "hack", but when the product doesn't support semi-joins for more than one column, sometimes you have no choice.
Example of where inner/outer join solution would not work:
select * from T1
where <boolean expression>
and (<boolean expression> OR (ColA, ColB) in (select A, B ...))
and <boolean expression>
...
When the queries aren't trivial in nature sometimes you don't have access to the base table set to perform regular inner/outer joins.
If you do use this "hack", when you combine fields just be sure to add enough of a delimiter in between them to avoid misinterpretations, e.g. ColA + ":-:" + ColB
Your Fundamentals are wrong, the program won't work, so go through the basics and rewrite the program.
Some of the corrections you must make are:
1) You must make a variable of semaphore type
sem_t semvar;
2) The functions sem_wait(), sem_post() require the semaphore variable but you are passing the semaphore id, which makes no sense.
sem_wait(&semvar);
//your critical section code
sem_post(&semvar);
3) You are passing the semaphore to sem_wait() and sem_post() without initializing it. You must initialize it to 1 (in your case) before using it, or you will have a deadlock.
ret = semctl( semid, 1, SETVAL, sem);
if (ret == 1)
perror("Semaphore failed to initialize");
Study the semaphore API's from the man page and go through this example.
So whilst all the answers here are good I wanted a bit more control over the output. For instance I'd like to prevent any near white shades, whilst ensuring I get bright vibrant colours not washed out shades.
function generateColor(ranges) {
if (!ranges) {
ranges = [
[150,256],
[0, 190],
[0, 30]
];
}
var g = function() {
//select random range and remove
var range = ranges.splice(Math.floor(Math.random()*ranges.length), 1)[0];
//pick a random number from within the range
return Math.floor(Math.random() * (range[1] - range[0])) + range[0];
}
return "rgb(" + g() + "," + g() + "," + g() +")";
};
So now I can specify 3 arbitrary ranges to pick rgb values from. You can call it with no arguments and get my default set which will usually generate a quite vibrant colour with once obvious dominant shade, or you can supply your own array of ranges.
I had the same issue where the project compiles fine (even after clean & build), but intellisense complains about missing references.
I tried everything from deleting the cache and disabling resharper, but nothing worked. In the end, I realized it was only a single project reference that showed intellisense errors.
My solution was to simply remove the reference to this project and add it again Everything worked as expected afterwards.
This is a sample program I wrote to check if a number is prime or not.
def is_prime(x):
y=0
if x<=1:
return False
elif x == 2:
return True
elif x%2==0:
return False
else:
root = int(x**.5)+2
for i in xrange (2,root):
if x%i==0:
return False
y=1
if y==0:
return True
if you are using vs code terminal you have to use this command
$env:NODE_ENV="production"
You can try below:
find ./ ! \( -path ./tmp -prune \) ! \( -path ./scripts -prune \) -type f -name '*_peaks.bed'
I had the same problem;
textStatus = 'error'
errorThrown = (empty)
xhr.status = 0
That fits my problem exactly. It turns out that when I was loading the HTML-page from my own computer this problem existed, but when I loaded the HTML-page from my webserver it went alright. Then I tried to upload it to another domain, and again the same error occoured. Seems to be a cross-domain problem. (in my case at least)
I have tried calling it this way also:
var request = $.ajax({
url: "http://crossdomain.url.net/somefile.php", dataType: "text",
crossDomain: true,
xhrFields: {
withCredentials: true
}
});
but without success.
This post solved it for me: jQuery AJAX cross domain
I'd suggest instead of doing another query with the same parameters just immediately running a SELECT FOUND_ROWS()
Use:
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
The option you should use is iDisplayLength:
$('#adminProducts').dataTable({
'iDisplayLength': 100
});
$('#table').DataTable({
"lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});
It will Load by default all entries.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
If you want to load by default 25 not all do this.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
});
// This worked for me.
<form name="myForm" class="css-form" novalidate ng-submit="Save(myForm.$invalid)">
<input type="text" name="uName" ng-model="User.Name" required/>
<span ng-show="User.submitted && myForm.uName.$error.required">Name is required.</span>
<input ng-click="User.submitted=true" ng-disabled="User.submitted && tForm.$invalid" type="submit" value="Save" />
</form>
// in controller
$scope.Save(invalid)
{
if(invalid) return;
// save form
}
I faced the problem of gettng entire text from Text widget and following solution worked for me :
txt.get(1.0,END)
Where 1.0 means first line, zeroth character (ie before the first!) is the starting position and END is the ending position.
Thanks to Alan Gauld in this link
No you don't need to call the base destructor, a base destructor is always called for you by the derived destructor. Please see my related answer here for order of destruction.
To understand why you want a virtual destructor in the base class, please see the code below:
class B
{
public:
virtual ~B()
{
cout<<"B destructor"<<endl;
}
};
class D : public B
{
public:
virtual ~D()
{
cout<<"D destructor"<<endl;
}
};
When you do:
B *pD = new D();
delete pD;
Then if you did not have a virtual destructor in B, only ~B() would be called. But since you have a virtual destructor, first ~D() will be called, then ~B().
the repr function will return a string which is the exact definition of your dict (except for the order of the element, dicts are unordered in python). unfortunately, i can't tell a way to automatically get a string which represent the variable name.
>>> dict = {'one': 1, 'two': 2}
>>> repr(dict)
"{'two': 2, 'one': 1}"
writing to a file is pretty standard stuff, like any other file write:
f = open( 'file.py', 'w' )
f.write( 'dict = ' + repr(dict) + '\n' )
f.close()
I assume that you are looking to do something interactive when the textbox changes (i.e. retrieve some data via ajax). I was looking for this same functionality. I know using a global isn't the most robust or elegant solution, but that is what I went with. Here is an example:
var searchValue = $('#Search').val();
$(function () {
setTimeout(checkSearchChanged, 0.1);
});
function checkSearchChanged() {
var currentValue = $('#Search').val();
if ((currentValue) && currentValue != searchValue && currentValue != '') {
searchValue = $('#Search').val();
$('#submit').click();
}
else {
setTimeout(checkSearchChanged, 0.1);
}
}
One key thing to note here is that I am using setTimeout and not setInterval since I don't want to send multiple requests at the same time. This ensures that the timer "stops" when the form is submitted and "starts" when the request is complete. I do this by calling checkSearchChanged when my ajax call completes. Obviously you could expand this to check for minimum length, etc.
In my case, I am using ASP.Net MVC so you can see how to tie this in with MVC Ajax as well in the following post:
since HashMap implements Serializable interface, you can simply use ObjectOutputStream class to write whole Map to file, and read it again using ObjectInputStream class
below simple code that explain usage of ObjectOutStream and ObjectInputStream
import java.util.*;
import java.io.*;
public class A{
HashMap<String,String> hm;
public A() {
hm=new HashMap<String,String>();
hm.put("1","A");
hm.put("2","B");
hm.put("3","C");
method1(hm);
}
public void method1(HashMap<String,String> map) {
//write to file : "fileone"
try {
File fileOne=new File("fileone");
FileOutputStream fos=new FileOutputStream(fileOne);
ObjectOutputStream oos=new ObjectOutputStream(fos);
oos.writeObject(map);
oos.flush();
oos.close();
fos.close();
} catch(Exception e) {}
//read from file
try {
File toRead=new File("fileone");
FileInputStream fis=new FileInputStream(toRead);
ObjectInputStream ois=new ObjectInputStream(fis);
HashMap<String,String> mapInFile=(HashMap<String,String>)ois.readObject();
ois.close();
fis.close();
//print All data in MAP
for(Map.Entry<String,String> m :mapInFile.entrySet()){
System.out.println(m.getKey()+" : "+m.getValue());
}
} catch(Exception e) {}
}
public static void main(String args[]) {
new A();

}
or if you want to write data as text to file you can simply iterate through Map and write key and value line by line, and read it again line by line and add to HashMap
import java.util.*;
import java.io.*;
public class A{
HashMap<String,String> hm;
public A(){
hm=new HashMap<String,String>();
hm.put("1","A");
hm.put("2","B");
hm.put("3","C");
method2(hm);
}
public void method2(HashMap<String,String> map) {
//write to file : "fileone"
try {
File fileTwo=new File("filetwo.txt");
FileOutputStream fos=new FileOutputStream(fileTwo);
PrintWriter pw=new PrintWriter(fos);
for(Map.Entry<String,String> m :map.entrySet()){
pw.println(m.getKey()+"="+m.getValue());
}
pw.flush();
pw.close();
fos.close();
} catch(Exception e) {}
//read from file
try {
File toRead=new File("filetwo.txt");
FileInputStream fis=new FileInputStream(toRead);
Scanner sc=new Scanner(fis);
HashMap<String,String> mapInFile=new HashMap<String,String>();
//read data from file line by line:
String currentLine;
while(sc.hasNextLine()) {
currentLine=sc.nextLine();
//now tokenize the currentLine:
StringTokenizer st=new StringTokenizer(currentLine,"=",false);
//put tokens ot currentLine in map
mapInFile.put(st.nextToken(),st.nextToken());
}
fis.close();

In 32 bit format system the hexadecimal value 0xff represents 00000000000000000000000011111111 that is 255(15*16^1+15*16^0) in decimal. and the bitwise & operator masks the same 8 right most bits as in first operand.
As per comments, First you need to install an instance of SQL Server if you don't already have one - https://msdn.microsoft.com/en-us/library/ms143219.aspx
Once this is installed you must connect to this instance (server) and then you can create a database here - https://msdn.microsoft.com/en-US/library/ms186312.aspx

yes you need to call repaint(); revalidate(); when you call removeAll() then you have to call repaint() and revalidate()
If you got here because a search engine told you this is how to get the Unix timestamp, stop reading this answer. Scroll down one.
If you want to reverse time.gmtime(), you want calendar.timegm().
>>> calendar.timegm(time.gmtime())
1293581619.0
You can turn your string into a time tuple with time.strptime(), which returns a time tuple that you can pass to calendar.timegm():
>>> import calendar
>>> import time
>>> calendar.timegm(time.strptime('Jul 9, 2009 @ 20:02:58 UTC', '%b %d, %Y @ %H:%M:%S UTC'))

I search the string (starting rightmost) for the first character in the range 1 to 9 (ASCII value 49-57) then null (set to 0) each char right of it - see below:
void stripTrailingZeros(void) {
//This finds the index of the rightmost ASCII char[1-9] in array
//All elements to the left of this are nulled (=0)
int i = 20;
unsigned char char1 = 0; //initialised to ensure entry to condition below
while ((char1 > 57) || (char1 < 49)) {
i--;
char1 = sprintfBuffer[i];
}
//null chars left of i
for (int j = i; j < 20; j++) {
sprintfBuffer[i] = 0;
}
}
Not really. for backward compatibility it is 32 bits.
If you want 64 bits you have long, size_t or int64_t

To know how to configure your project to deal with this code , complete reading this tutorial .
Add the following to your build.gradle
apply plugin: 'eclipse'
and browse to the project directory
gradle eclipse
Once done, you could import the project from eclipse as simple Java Project.
Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:
#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"
The shift will remove the first argument, renaming the rest ($2 becomes $1, and so on).$@` refers to the arguments, as an array of words (it must be quoted!).
If you must have your --file syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1" with whatever parsing of $1 you need to do, perhaps using getopt or getopts.
If you want to roll your own, for just the one specific case, you could do something like this:
if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
ext_program="${1:7}"
else
ext_program="default program"
fi
filter_input(INPUT_POST, 'var_name') instead of $_POST['var_name']
filter_input_array(INPUT_POST) instead of $_POST
This is not only a 'newbie' scenario. I just ran across this compiler message (GCC 5.4) when refactoring a class to remove some constructor parameters. I forgot to update both the declaration and definition, and the compiler spit out this unintuitive error.
The bottom line seems to be this: If the compiler can't match the definition's signature to the declaration's signature it thinks the definition is not a constructor and then doesn't know how to parse the code and displays this error. Which is also what happened for the OP: std::string is not the same type as string so the declaration's signature differed from the definition's and this message was spit out.
As a side note, it would be nice if the compiler looked for almost-matching constructor signatures and upon finding one suggested that the parameters didn't match rather than giving this message.
It don't create normally; you need to add it by yourself.
After adding Global.asax by
You need to add a class
Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.
Your Global.asax will look like this: -
<%@ Application Language="C#" Inherits="Global" %>
Your Global.cs in App_Code will look like this: -
public class Global : System.Web.HttpApplication
{
public Global()
{
//
// TODO: Add constructor logic here
//
}
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}
/// Many other events like begin request...e.t.c, e.t.c
}
select a.ip, a.os, a.hostname, a.port, a.protocol,
b.state
from a
left join b on a.ip = b.ip
and a.port = b.port
string stringToDecrypt = HttpContext.Current.Request.QueryString.ToString()
//change to string stringToDecrypt = HttpUtility.UrlDecode(HttpContext.Current.Request.QueryString.ToString())
To make sure it will work, you need to validate it.
function mmIsDate(str) {
if (str == undefined) { return false; }
var parms = str.split(/[\.\-\/]/);
var yyyy = parseInt(parms[2], 10);
if (yyyy < 1900) { return false; }
var mm = parseInt(parms[1], 10);
if (mm < 1 || mm > 12) { return false; }
var dd = parseInt(parms[0], 10);
if (dd < 1 || dd > 31) { return false; }
var dateCheck = new Date(yyyy, mm - 1, dd);
return (dateCheck.getDate() === dd && (dateCheck.getMonth() === mm - 1) && dateCheck.getFullYear() === yyyy);
};
aaa##HTML I would suggest you wrap them in a div, since you will likely end up floating them in certain contexts.
<div class="input-w">
<label for="your-input">Your label</label>
<input type="text" id="your-input" />
</div>
Then within that div, you can make each piece inline-block so that you can use vertical-align to center them - or set baseline etc. (your labels and input might change sizes in the future...
.input-w label, .input-w input {
float: none; /* if you had floats before? otherwise inline-block will behave differently */
display: inline-block;
vertical-align: middle;
}
This is how I do things these days.
<label class='input-w' for='this-input-name'>
<span class='label'>Your label</span>
<input class='input' type='text' id='this-input-name' placeholder='hello'>
</label>
<label class='input-w' for='this-other-input-name'>
<span class='label'>Your label</span>
<input class='input' type='text' id='this-other-input-name' placeholder='again'>
</label>

Take a look at the Activator.CreateInstance method.
hash_items = {:item => 1}
puts hash_items
#hash_items will give you {:item => 1}
hash_items.merge!({:item => 2})
puts hash_items
#hash_items will give you {:item => 1, :item => 2}
hash_items.merge({:item => 2})
puts hash_items
#hash_items will give you {:item => 1, :item => 2}, but the original variable will be the same old one.
The bottom statement is equivalent to:
.half {
flex-grow: 0;
flex-shrink: 0;
flex-basis: 50%;
}
Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.
Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.
I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

When you use the finish() method, it does not close the process completely , it is STILL working in background.
Please use this code in Main Activity (Please don't use in every activities or sub Activities):
@Override

In VS 2013 I saw this error after setting up Google Docs synchronization on My Documents. Updated permissions to not be read-only and problem solved.
Just 2 small improvements to the above suggestions:
stop propagation on the event that triggered this, assuming its a click
jQuery(thelink).click(function(e){
jQuery(thepop).show();
// bind the hide controls
var jpop=jQuery(thepop);
jQuery(document).bind("click.hidethepop", function() {
jpop.hide();
// unbind the hide controls
jQuery(document).unbind("click.hidethepop");
});
// dont close thepop when you click on thepop
jQuery(thepop).click(function(e) {
e.stopPropagation();
});
// and dont close thepop now
e.stopPropagation();
});
Imagine what happens if x[l] is neither 0 nor 1 in the loop. In that case a and b will never be assigned to and have an undefined value. You must initialize them both with some value, for example 0.
A Simple approach to change the Font Size in Visual Studio Work Environment :
Go To : File -> Preferences -> Settings OR Press CTRL+, i.e. CTRL + COMMA.
This will open settings.json.
You can see 3 tabs there :
Go to User Settings and Add this :
{
"editor.fontSize": 16
}
Now just save and close the file.
In above code, 16 represents the font size. Increase of Decrease as per your wish.
If you run into this problem with Visual Studio 2019 (VS2019), you can download the build tools from https://visualstudio.microsoft.com/downloads/. And, under Tools for Visual Studio 2019 and download Build Tools for Visual Studios 2019.
You need to use absolutely-positioned CSS over a relatively-positioned img tag. The article Text Blocks Over Image gives a step-by-step example for placing text over an image.
I had a very similar problem where for the form action, I had something like:
<form action="http://www.example.com/?q=content/something" method="GET">
<input type="submit" value="Go away..." />
</form>
The button would get the user to the site, but the query info disappeared so the user landed on the home page rather than the desired content page. The solution in my case was to find out how to code the URL without the query that would get the user to the desired page. In this case my target was a Drupal site, so as it turned out /content/something also worked. I also could have used a node number (i.e. /node/123).
Use the .Select() after grouping:
var agencyContracts = _agencyContractsRepository.AgencyContracts
.GroupBy(ac => new
{
ac.AgencyContractID, // required by your view model. should be omited
// in most cases because group by primary key
// makes no sense.
ac.AgencyID,
ac.VendorID,
ac.RegionID
})
.Select(ac => new AgencyContractViewModel
{
AgencyContractID = ac.Key.AgencyContractID,
AgencyId = ac.Key.AgencyID,
VendorId = ac.Key.VendorID,
RegionId = ac.Key.RegionID,
Amount = ac.Sum(acs => acs.Amount),
Fee = ac.Sum(acs => acs.Fee)
});
use a negative character class:
[^,;]+
Strictly with sed:
grep ... | sed -e 's/^\(.\{N\}\).*$/\1/'
you could try something like this:
import java.text.*;
import java.util.*;
public class DtTime {
public static void main(String args[]) {
String s;
Format formatter;
Date date = new Date();
formatter = new SimpleDateFormat("dd/MM/yyyy");
s = formatter.format(date);
System.out.println(s);
}
}
This will give you output as21/03/2012
Or you could try this if you want the output as 21 Mar, 2012
import java.text.*;
import java.util.*;
public class DtTime {
public static void main(String args[]) {
Date date=new Date();
String df=DateFormat.getDateInstance().format(date);
System.out.println(df);
}
}
Even the first answer is absolutely brilliant, you probably want to only run script under sudo.
You have to specify the absolute path like:
sudo /home/user/example.sh
sudo ~/example.sh
(both are working)
THIS WONT WORK!
sudo /bin/sh example.sh
sudo example.sh
It will always return
sudo: bin/sh: command not found
sudo: example.sh: command not found
With Java 8 in picture, jcmd is the preferred approach.
jcmd <PID> Thread.print
Following is the snippet from Oracle documentation :
The release of JDK 8 introduced Java Mission Control, Java Flight Recorder, and jcmd utility for diagnosing problems with JVM and Java applications. It is suggested to use the latest utility, jcmd instead of the previous jstack utility for enhanced diagnostics and reduced performance overhead.
However, shipping this with the application may be licensing implications which I am not sure.
Using the HttpClientBuilder in HttpClient 4.5.x with a custom HttpClientConnectionManager with the defaults of HttpClientBuilder :
SSLConnectionSocketFactory sslConnectionSocketFactory =
new SSLConnectionSocketFactory(SSLContexts.createDefault(),
new String[] { "TLSv1.2" },
null,
SSLConnectionSocketFactory.getDefaultHostnameVerifier());
PoolingHttpClientConnectionManager poolingHttpClientConnectionManager =
new PoolingHttpClientConnectionManager(
RegistryBuilder.<ConnectionSocketFactory> create()
.register("http",
PlainConnectionSocketFactory.getSocketFactory())
.register("https",
sslConnectionSocketFactory)
.build());
// Customize the connection pool
CloseableHttpClient httpClient = HttpClientBuilder.create()
.setConnectionManager(poolingHttpClientConnectionManager)
.build()
Without a custom HttpClientConnectionManager :
SSLConnectionSocketFactory sslConnectionSocketFactory =
new SSLConnectionSocketFactory(SSLContexts.createDefault(),
new String[] { "TLSv1.2" },
null,
SSLConnectionSocketFactory.getDefaultHostnameVerifier());
CloseableHttpClient httpClient = HttpClientBuilder.create()
.setSSLSocketFactory(sslConnectionSocketFactory)
.build()
Here:
df = df.reset_index()
df.columns[0] = 'New_ID'
df['New_ID'] = df.index + 880
Simple prevent the default behavior of click, dblclick or touchend events will disable the zoom functionality.
If you have already a callback on one of this events just call a event.preventDefault().
You can use library to help to change time zone
moment-timezone
var moment = require("moment-timezone");
const today = new Date();
var timeGet = moment(today);
timeGet.tz("Asia/Karachi").format("ha z");`
this can change your time zone of your region paste your region area and get real gmt+ resolve issue
First you need to ask, why you want to do this?
But it's possible via:
t = ('275', '54000', '0.0', '5000.0', '0.0')
lst = list(t)
lst[0] = '300'
t = tuple(lst)
But if you're going to need to change things, you probably are better off keeping it as a list
If you would like to write your own, you can start with this six-part document detailing effective usage of C# 2.0 data structures and how to go about analyzing your implementation of data structures in C#. Each article has examples and an installer with samples you can follow along with.

There's now a new css3 property for this: text-decoration-color
So you can now have text in one color and a text-decoration underline - in a different color... without needing an extra 'wrap' element
p {_x000D_
text-decoration: underline;_x000D_
-webkit-text-decoration-color: red; /* safari still uses vendor prefix */_x000D_
text-decoration-color: red;_x000D_
}<p>black text with red underline in one element - no wrapper elements here!</p>NB:
1) Browser Support is limited at the moment to Firefox and Chrome (fully supported as of V57) and Safari
2) You could also use the text-decoration shorthand property which looks like this:
<text-decoration-line> || <text-decoration-style> || <text-decoration-color>
...so using the text-decoration shorthand - the example above would simply be:
p {
text-decoration: underline red;
}
p {_x000D_
text-decoration: underline red;_x000D_
}<p>black text with red underline in one element - no wrapper elements here!</p>I think, this is the simplest technique to beautify the json data,
String indented = (new JSONObject(Response)).toString(4);
where Response is a String.
Simply pass the 4(indentSpaces) in toString() method.
Note: It works fine in the android without any library. But in java you have to use the org.json library.
One way we do this in our application is using IDisposable and then with using(){} blocks to ensure the cursor is reset when done.
public class OverrideCursor : IDisposable
{
public OverrideCursor(Cursor changeToCursor)
{
Mouse.OverrideCursor = changeToCursor;
}
#region IDisposable Members
public void Dispose()
{
Mouse.OverrideCursor = null;
}
#endregion
}
and then in your code:
using (OverrideCursor cursor = new OverrideCursor(Cursors.Wait))
{
// Do work...
}
The override will end when either: the end of the using statement is reached or; if an exception is thrown and control leaves the statement block before the end of the statement.
Update
To prevent the cursor flickering you can do:
public class OverrideCursor : IDisposable
{
static Stack<Cursor> s_Stack = new Stack<Cursor>();
public OverrideCursor(Cursor changeToCursor)
{
s_Stack.Push(changeToCursor);
if (Mouse.OverrideCursor != changeToCursor)
Mouse.OverrideCursor = changeToCursor;
}
public void Dispose()
{
s_Stack.Pop();
Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;
if (cursor != Mouse.OverrideCursor)
Mouse.OverrideCursor = cursor;
}
}
If you just want to clobber all of the instances of a substring out of a string without using regex you can using:
var replacestring = "A B B C D"
const oldstring = "B";
const newstring = "E";
while (replacestring.indexOf(oldstring) > -1) {
replacestring = replacestring.replace(oldstring, newstring);
}
//result: "A E E C D"
Adding the GridView1.DataBind() to the button click event did not work for me. However, adding it to the SqlDataSource1_Updated event did though.
Protected Sub SqlDataSource1_Updated(sender As Object, e As SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Updated
GridView1.DataBind()
End Sub
I also faced similar issue.
My source path had one directory with 'space' (D:/source 2012). I resolved this by removing the space (D:/source2012).
I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.
if adding dependencies haven`t solved your problem, create WAR archive again. In my case, I used obsolete WAR file without security-web and security-conf jars
I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().
Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.
So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.
For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.
exec('some_command 2>&1', $output);
print_r($output); // to see the response to your command
Thanks for all the help guys, I appreciate it ;)
You can find API KEY from the google-services.json file
You inherit class attributes, not class constructors .This is how it goes :
If no constructor is added in the super class, if no then the compiler adds a no argument contructor. This default constructor is invoked implicitly whenever a new instance of the sub class is created . Here the sub class may or may not have constructor, all is ok .
if a constructor is provided in the super class, the compiler will see if it is a no arg constructor or a constructor with parameters.
if no args, then the compiler will invoke it for any sub class instanciation . Here also the sub class may or may not have constructor, all is ok .
if 1 or more contructors in the parent class have parameters and no args constructor is absent, then the subclass has to have at least 1 constructor where an implicit call for the parent class construct is made via super (parent_contractor params) .
this way you are sure that the inherited class attributes are always instanciated .
You probably want an extra wrapper. use a div for the background and position it below your content..

perhaps, you can first determine if the DOM does really exists,
function walkmydog() {
//when the user starts entering
var dom = document.getElementById('WallSearch');
if(dom == null){
alert('sorry, WallSearch DOM cannot be found');
return false;
}
if(dom.value.length == 0){
alert("nothing");
}
}
if (document.addEventListener){
document.addEventListener("DOMContentLoaded", walkmydog, false);
}
try this out:

`userName`,
`carPrice`
FROM `users`
LEFT JOIN `cars`
ON cars.belongsToUser=users.id
WHERE `id`='4'
ORDER BY `carPrice` DESC

It seems that the version "20140702" of the example link in the question was the final version, because I downloaded this file on the 12th November 2014, i.e. the version from the 2nd of July 2014 was still the latest version on 12th of November. When I try manually all the possible versions/dates between today in this date, then I always get a page with error code "404" (file not found), which indicates that no new version was released since the 12th of November.
I haven't tried specifically getting the VM settings, but there is a wealth of information in the JMX utilities specifically the MXBean utilities. This would be where I would start. Hopefully you find something there to help you.

I'm a little confused about custom made completion handlers. In your example:
Say you have a download function to download a file from network,and want to be notified when download task has finished.
typealias CompletionHandler = (success:Bool) -> Void
func downloadFileFromURL(url: NSURL,completionHandler: CompletionHandler) {
// download code.
let flag = true // true if download succeed,false otherwise
completionHandler(success: flag)
}
Your // download code will still be ran asynchronously. Why wouldn't the code go straight to your let flag = true and completion Handler(success: flag) without waiting for your download code to be finished?
This is probably the simplest way:
data$rownumber = 1:dim(data)[1]
It's probably worth noting that if you want to select a row by its row index, you can do this with simple bracket notation
data[3,]
vs.
data[data$rownumber==3,]
So I'm not really sure what this new column accomplishes.
Today date:
$( ".selector" ).datepicker( "setDate", new Date());
// Or on the init
$( ".selector" ).datepicker({ defaultDate: new Date() });
15 days from today:
$( ".selector" ).datepicker( "setDate", 15);
// Or on the init
$( ".selector" ).datepicker({ defaultDate: 15 });

As an addendum, if you are using this technique to define strings in your target, this is how I had to define and use them:
In Build Settings -> Preprocessor Macros, and yes backslashes are critical in the definition:
APPURL_NSString=\@\"www.foobar.org\"
And in the source code:
objectManager.client.baseURL = APPURL_NSString;
