From MSDN: System.Threading.Timer
is a simple, lightweight timer that uses callback methods and is served by thread pool threads. It is not recommended for use with Windows Forms, because its callbacks do not occur on the user interface thread. System.Windows.Forms.Timer
is a better choice for use with Windows Forms. For server-based timer functionality, you might consider using System.Timers.Timer
, which raises events and has additional features.
Use org.springframework.web.context.request.WebRequest
as a parameter in your controller method, it provides the method getParameterMap()
, the advantage is that you do not tight your application to the Servlet API, the WebRequest is a example of JavaEE pattern Context Object.
I just copy pasted the database folders to data folder in MySQL, i.e. If you have a database called alto then find the folder alto in your MySQL -> Data folder in your backup and copy the entire alto folder and past it to newly installed MySQL -> data folder, restart the MySQL and this works perfect.
I've used bootstrap header classes ("h1", "h2", etc.) for this. This way you get all the style benefits without using the actual tags. Here is an example:
<div class="h3"><span class="glyphicon glyphicon-tags" aria-hidden="true"></span></div>
If you are having multiple child Div's inside your parent Div, then you can use vertical-align property something like below :
.Parent div
{
vertical-align : bottom;
}
I was looking for a similar solution, but the ones mentioned here would not work. My data had all variations of whitespace (space, newline, tab) chars and commas.
To make the column data tsv safe, I replaced all \t chars in the column data with a space, and executed python code on the commandline to generate a csv file, as shown below:
hive -e 'tab_replaced_hql_query' | python -c 'exec("import sys;import csv;reader = csv.reader(sys.stdin, dialect=csv.excel_tab);writer = csv.writer(sys.stdout, dialect=csv.excel)\nfor row in reader: writer.writerow(row)")'
This created a perfectly valid csv. Hope this helps those who come looking for this solution.
For Eclipse Users. If you have a Run Configuration that does clean package for example.
In the Run Configuration panel there is a JRE tab where you can specify against which runtime it should run. Note that this configuration overrides whatever is in the pom.xml.
I recently had to do this for Textboxes and Checkboxes but using JavaScript ...
How to reset textbox and checkbox controls in an ASP.net document
Here is the code ...
<script src="http://code.jquery.com/jquery-1.7.1.js" type="text/javascript"></script>
<script type="text/javascript">
function ResetForm() {
//get the all the Input type elements in the document
var AllInputsElements = document.getElementsByTagName('input');
var TotalInputs = AllInputsElements.length;
//we have to find the checkboxes and uncheck them
//note: <asp:checkbox renders to <input type="checkbox" after compiling, which is why we use 'input' above
for(var i=0;i< TotalInputs ; i++ )
{
if(AllInputsElements[i].type =='checkbox')
{
AllInputsElements[i].checked = false;
}
}
//reset all textbox controls
$('input[type=text], textarea').val('');
Page_ClientValidateReset();
return false;
}
//This function resets all the validation controls so that they don't "fire" up
//during a post-back.
function Page_ClientValidateReset() {
if (typeof (Page_Validators) != "undefined") {
for (var i = 0; i < Page_Validators.length; i++) {
var validator = Page_Validators[i];
validator.isvalid = true;
ValidatorUpdateDisplay(validator);
}
}
}
</script>
And call it with a button or any other method ...
<asp:button id="btnRESET" runat="server" onclientclick="return ResetForm();" text="RESET" width="100px"></asp:button>
If you don't use ValidationControls on your website, just remove all the code refering to it above and the call Page_ClientValidateReset();
I am sure you can expand it for any other control using the DOM. And since there is no post to the server, it's faster and no "flashing" either.
In most regex implementations (including Java's), :
has no special meaning, neither inside nor outside a character class.
Your problem is most likely due to the fact the -
acts as a range operator in your class:
[A-Za-z0-9.,-:]*
where ,-:
matches all ascii characters between ','
and ':'
. Note that it still matches the literal ':'
however!
Try this instead:
[A-Za-z0-9.,:-]*
By placing -
at the start or the end of the class, it matches the literal "-"
. As mentioned in the comments by Keoki Zee, you can also escape the -
inside the class, but most people simply add it at the end.
A demo:
public class Test {
public static void main(String[] args) {
System.out.println("8:".matches("[,-:]+")); // true: '8' is in the range ','..':'
System.out.println("8:".matches("[,:-]+")); // false: '8' does not match ',' or ':' or '-'
System.out.println(",,-,:,:".matches("[,:-]+")); // true: all chars match ',' or ':' or '-'
}
}
As RPM1984 refers to, this is mostly likely caused by the fact that your script is loading before jQuery is loaded.
Use the location header flag:
curl -L <URL>
dtypes is a Pandas Series. That means it contains index & values attributes. If you only need the column names:
headers = df.dtypes.index
it will return a list containing the column names of "df" dataframe.
In case you're sure you have only one space between two words, you can use this one
str.replace(/\s+/g, ' ').split(' ')
so you replace one space by two, the split by space
Here is a generic script you can use in SQL server. just amend the start and end dates:
IF EXISTS (SELECT * FROM information_schema.tables WHERE Table_Name = 'Calendar' AND Table_Type = 'BASE TABLE')
BEGIN
DROP TABLE [Calendar]
END
CREATE TABLE [Calendar]
(
[CalendarDate] DATETIME
)
DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = GETDATE()
SET @EndDate = DATEADD(d, 365, @StartDate)
WHILE @StartDate <= @EndDate
BEGIN
INSERT INTO [Calendar]
(
CalendarDate
)
SELECT
@StartDate
SET @StartDate = DATEADD(dd, 1, @StartDate)
END

C# uses the UTF16 format for its strings.
So, besides just converting the types, you should also be conscious about the string's actual format.
When compiling for Multi-byte Character set Visual Studio and the Win API assumes UTF8 (Actually windows encoding which is Windows-28591 ).
When compiling for Unicode Character set Visual studio and the Win API assume UTF16.
So, you must convert the string from UTF16 to UTF8 format as well, and not just convert to std::string.
This will become necessary when working with multi-character formats like some non-latin languages.
The idea is to decide that std::wstring
always represents UTF16.
And std::string
always represents UTF8.
This isn't enforced by the compiler, it's more of a good policy to have.
#include "stdafx.h"
#include <string>
#include <codecvt>
#include <msclr\marshal_cppstd.h>
using namespace System;
int main(array<System::String ^> ^args)
{
System::String^ managedString = "test";
msclr::interop::marshal_context context;
//Actual format is UTF16, so represent as wstring
std::wstring utf16NativeString = context.marshal_as<std::wstring>(managedString);
//C++11 format converter
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> convert;
//convert to UTF8 and std::string
std::string utf8NativeString = convert.to_bytes(utf16NativeString);
return 0;
}
Or have it in a more compact syntax:
int main(array<System::String ^> ^args)
{
System::String^ managedString = "test";
msclr::interop::marshal_context context;
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> convert;
std::string utf8NativeString = convert.to_bytes(context.marshal_as<std::wstring>(managedString));
return 0;
}
Finding the correct intersection of two line segments is a non-trivial task with lots of edge cases. Here's a well documented, working and tested solution in Java.
In essence, there are three things that can happen when finding the intersection of two line segments:
The segments do not intersect
There is a unique intersection point
The intersection is another segment
NOTE: In the code, I assume that a line segment (x1, y1), (x2, y2) with x1 = x2 and y1 = y2 is a valid line segment. Mathematically speaking, a line segment consists of distinct points, but I am allowing segments to be points in this implementation for completeness.
Code is taken from my github repo

* The intersection may either be empty, a single point or the

Browser scrollbars don't work at all on iPhone/iPad. At work we are using custom JavaScript scrollbars like jScrollPane to provide a consistent cross-browser UI: http://jscrollpane.kelvinluck.com/
It works very well for me - you can make some really beautiful custom scrollbars that fit the design of your site.
Though the earlier answers are correct, there's a small complication it would help to remark on.

let dateValue:NSDate? = dateFormatter.dateFromString(dataString)
if you have and date picker parse date like this
// to avoid any nil value
if let isDate = dateValue {
self.datePicker.date = isDate

This error usually means you've forgotten a closing quote somewhere in the template you're trying to render. For example: {% url 'my_view %}
(wrong) instead of {% url 'my_view' %}
(correct). In this case it's the colon that's causing the problem. Normally you'd edit the template to use the correct {% url %}
syntax.
But there's no reason why the django admin site would throw this, since it would know it's own syntax. My best guess is therefore that grapelli
is causing your problem since it changes the admin templates. Does removing grappelli from installed apps help?

This is as good as passing variable arguments by means of a dictionary
Either:
DateTime dt = new DateTime();
or
DateTime dt = default(DateTime);

This is how I did it and it works:
dictlist = [dict() for x in range(n)]
It gives you a list of n empty dictionaries.
In the accepted answer the ConcurrentBag is not required. Here's an implementation without it:
var tasks = myCollection.Select(GetData).ToList();
await Task.WhenAll(tasks);
var results = tasks.Select(t => t.Result);
Any of the "// some pre stuff" and "// some post stuff" can go into the GetData implementation (or another method that calls GetData)
Aside from being shorter, there's no use of an "async void" lambda, which is an anti pattern.
Just use this constructor of List<T>
. It accepts any IEnumerable<T>
as an argument.
string[] arr = ...
List<string> list = new List<string>(arr);
You can use
setInterval(function(){
document.getElementById("yourbutton").click();
}, 1000);
Another easy way to do it so that it is referenced in the project folder you want, like "Frameworks", is to:
It will appear in both the project navigator where you want it, as well as in the "Link Binary With Libraries" area of the "Build Phases" pane of your target.
This problem arose for me when I installed Anaconda multiple times. I was careful to do an uninstall but there are some things that the uninstall process doesn't undo.
In my case, I needed to remove a file Microsoft.PowerShell_profile.ps1
from ~\Documents\WindowsPowerShell\
. I identified that this file was the culprit by opening it in a text editor. I saw that it referenced the old installation location C:\Anaconda3\
.
@Mayur "4.2 [Using query with complex JOIN]" with Common Table Expressions (CTEs) did the trick for me.
WITH cte AS (
SELECT e.id, e.postcode
FROM employees e
LEFT JOIN locations lc ON lc.postcode=cte.postcode
WHERE e.id=1
)
UPDATE employee_location SET lat=lc.lat, longitude=lc.longi
FROM cte
WHERE employee_location.id=cte.id;
Hope this helps... :D
An advanced Macro for handling Cursor Color, Position and properties For Windows 10.
Please refer to the help and usage examples for information on usage.
Supports and Shows examples of:
Edit:
I've included below the final usage example a command line that uses VT codes to achieve the same result as that example, to illustrate the difference in readability when using multiple Terminal sequences in the same Cursor output.
NOTES On changing Buffers:
Cursor position is tied to the active buffer; It is not availale when switching to an alternate buffer.
When reverting to the main buffer:
The cursor position originally occupied in the main buffer is restored, and the content of the alternate buffer is discarded.
::: Cout cursor Macro. Author: T3RRY ::: Filename: Cout.bat
::: OS requirement: Windows 10
::: Purpose: Facilitate advanced console display output with the easy use of Virtual terminal codes
::: Uses a macro function to effect display without users needing to memorise or learn specific
::: virtual terminal sequences.
::: Enables output of text in 255 bit color at absolute or relative Y;X positions.
::: Allows cursor to be hidden or shown during and after text output. See help for more info.

In case someone stumbled upon this problem when working on Grails (or pure Spring) web application, here is the post that helped me:
http://forum.spring.io/forum/spring-projects/web/2491-solved-character-encoding-and-multipart-forms
To set default encoding to UTF-8 (instead of the ISO-8859-1) for multipart requests, I added the following code in resources.groovy (Spring DSL):
multipartResolver(ContentLengthAwareCommonsMultipartResolver) {
defaultEncoding = 'UTF-8'
}
This service returns Countries (name,code) and cities for any country as REST, SErvice. You can also download database and sample REST service

Some sample code for animating an expand/collapse action using a table view section header is provided by Apple here: Table View Animations and Gestures
The key to this approach is to implement - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
and return a custom UIView which includes a button (typically the same size as the header view itself). By subclassing UIView and using that for the header view (as this sample does), you can easily store additional data such as the section number.
I was trying to use aws-vault which uses pass and gnugp2 (gpg2). I'm on Ubuntu 20.04 running in WSL2.
I tried all the solutions above, and eventually, I had to do one more thing -
$ rm ~/.gnupg/S.* # remove cache
$ gpg-connect-agent reloadagent /bye # restart gpg agent
$ export GPG_TTY=$(tty) # prompt for password
# ^ This last line should be added to your ~/.bashrc file
The source of this solution is from some blog-post in Japanese, luckily there's Google Translate :)
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;
cd to the directory that contains the script, or put it in a bin folder that is in your $PATH
then type
./scriptname.sh
if in the same directory or
scriptname.sh
if it's in the bin folder.
Try this. Note there's no database specified - it just runs "on the server"
psql -U postgres -c "drop database databasename"
If that doesn't work, I have seen a problem with postgres holding onto orphaned prepared statements.
To clean them up, do this:
SELECT * FROM pg_prepared_xacts;
then for every id you see, run this:
ROLLBACK PREPARED '<id>';

For me, changing the Start In location (of git-gui at least) did not affect where it looked for .gitconfig. My setup at work mounts U: for our home, but we do not have permission to write in U: directly, only subdirectories which were created for us inside, so this was a deal-breaker for me.
I solved the problem by making a batch script which would override the HOMEDRIVE and HOMEPATH env variables just for that application. Then changed my Start menu shortcut to point to that batch script instead.
For asynchronous version! And with the promise version! Here the clean simple way!
try {
await fsPromise.stat(filePath);
/**
* File exists!
*/
// do something
} catch (err) {
if (err.code = 'ENOENT') {
/**
* File not found
*/
} else {
// Another error!
}
}
A more practical snippet from my code to illustrate better:
try {
const filePath = path.join(FILES_DIR, fileName);
await fsPromise.stat(filePath);
/**
* File exists!
*/
const readStream = fs.createReadStream(
filePath,
{
autoClose: true,
start: 0
}
);
return {
success: true,
readStream
};
} catch (err) {
/**
* Mapped file doesn't exists
*/
if (err.code = 'ENOENT') {
return {
err: {
msg: 'Mapped file doesn\'t exists',
code: EErrorCode.MappedFileNotFound
}
};
} else {
return {
err: {
msg: 'Mapped file failed to load! File system error',
code: EErrorCode.MappedFileFileSystemError
}
};
}
}
The example above is just for demonstration! I could have used the error event of the read stream! To catch any errors! And skip the two calls!
HTML / HTTP is stateless, in other words, what you did / saw on the previous page, is completely unconnected with the current page. Except if you use something like sessions, cookies or GET / POST variables. Sessions and cookies are quite easy to use, with session being by far more secure than cookies. More secure, but not completely secure.
Session:
//On page 1
$_SESSION['varname'] = $var_value;
//On page 2
$var_value = $_SESSION['varname'];
Remember to run the session_start();
statement on both these pages before you try to access the $_SESSION
array, and also before any output is sent to the browser.
Cookie:
//One page 1
$_COOKIE['varname'] = $var_value;
//On page 2
$var_value = $_COOKIE['varname'];
The big difference between sessions and cookies is that the value of the variable will be stored on the server if you're using sessions, and on the client if you're using cookies. I can't think of any good reason to use cookies instead of sessions, except if you want data to persist between sessions, but even then it's perhaps better to store it in a DB, and retrieve it based on a username or id.
GET and POST
You can add the variable in the link to the next page:
<a href="page2.php?varname=<?php echo $var_value ?>">Page2</a>
This will create a GET variable.
Another way is to include a hidden field in a form that submits to page two:
<form method="get" action="page2.php">
<input type="hidden" name="varname" value="var_value">
<input type="submit">
</form>
And then on page two:
//Using GET
$var_value = $_GET['varname'];
//Using POST
$var_value = $_POST['varname'];
//Using GET, POST or COOKIE.
$var_value = $_REQUEST['varname'];
Just change the method for the form to post
if you want to do it via post. Both are equally insecure, although GET is easier to hack.
The fact that each new request is, except for session data, a totally new instance of the script caught me when I first started coding in PHP. Once you get used to it, it's quite simple though.
This worked for me, source: here
I had this error and it wasn't related with the DB constrains (at least in my case). I have an .xsd file with a GetRecord query that returns a group of records. One of the columns of that table was "nvarchar(512)" and in the middle of the project I needed to changed it to "nvarchar(MAX)".
Everything worked fine until the user entered more than 512 on that field and we begin to get the famous error message "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."
Solution: Check all the MaxLength property of the columns in your DataTable.
The column that I changed from "nvarchar(512)" to "nvarchar(MAX)" still had the 512 value on the MaxLength property so I changed to "-1" and it works!!.
The TimeOfDay
property returns a TimeSpan
value.
Try the following code:
TimeSpan time = DateTime.Now.TimeOfDay;
if (time > new TimeSpan(11, 59, 00) //Hours, Minutes, Seconds
&& time < new TimeSpan(13, 01, 00)) {
//match found
}
Also, new DateTime()
is the same as DateTime.MinValue
and will always be equal to 1/1/0001 12:00:00 AM
. (Value types cannot have non-empty default values) You want to use DateTime.Now
.
I'm going to offer up a way to return a boolean based on passing an argument of a reflection Kinds to a local type receiver (because I couldn't find anything like this).
First, we declare our anonymous type of type reflect.Value:
type AnonymousType reflect.Value
Then we add a builder for our local type AnonymousType which can take in any potential type (as an interface):
func ToAnonymousType(obj interface{}) AnonymousType {
return AnonymousType(reflect.ValueOf(obj))
}
Then we add a function for our AnonymousType struct which asserts against a reflect.Kind:
func (a AnonymousType) IsA(typeToAssert reflect.Kind) bool {
return typeToAssert == reflect.Value(a).Kind()
}
This allows us to call the following:
var f float64 = 3.4
anon := ToAnonymousType(f)
if anon.IsA(reflect.String) {
fmt.Println("Its A String!")
} else if anon.IsA(reflect.Float32) {
fmt.Println("Its A Float32!")

Since this keeps coming up in search results for making git and github work with SSH on Windows (and because I didn't need anything from the guides above), I'm adding the following, simple solution.
(Microsoft says they are working on adding SSH to Visual Studio, and GitHub for Windows still doesn't support SSH...)
1. I installed "git for Windows" (which includes ssh and a bash shell)
https://git-scm.com/download/win
2. From the included bash shell (which, for me, was installed at: C:\Program Files\Git\git-bash.exe
)
cd
to the root level of where you want your repo saved (something like: C:\code\github\
), and
Type:
eval $(ssh-agent -s) && ssh-add "C:\Users\YOURNAMEHERE\.ssh\github_rsa"
3. Type: (the SSH link from the repo)
git clone [email protected]:RepoName/Project.git
As discussed somewhat in the question comments, this is one way you could do it:
<input ... ng-model="$parent.storeDefault" value="{{location.id}}">
The above assumes that each location has a field (e.g., id) that holds a unique value.
Note that $parent.storeDefault is used because ng-repeat creates a child scope, and we want to manipulate the storeDefault parameter on the parent scope.
This command will show also if the file is hidden
adb shell ls -laR | grep filename
Faced the same issue post Firefox update to 29.0.1, this is also listed out here https://bugzilla.mozilla.org/show_bug.cgi?id=947728
Solutions:
They(Mozilla guys) have fixed this by introducing support for "-moz-appearance" for <input type="number">
.
You just need to have a style associated with your input field with "-moz-appearance:textfield;
".
I prefer the CSS way E.g.:-
.input-mini{
-moz-appearance:textfield;}
Or
You can do it inline as well:
<input type="number" style="-moz-appearance: textfield">
Boost has a macro that will do this for you.
1) I had to do the following with my configuration: (Add BackConnectionHostNames or Disable Loopback Check) http://support.microsoft.com/kb/896861
2) I was working off a dev system on an isolated dev network. I had gotten it working using the dev system's computer name in the URL to the web service, but when I modified the URL to the URL that would be used in production (rather than the computer name), I started getting the NTLM error.
3) I noticed the security log showed that the service account failing to login with an error similar to the one in the MSDN article.
4) Adding the BackConnectionHostNames made it so I could log into the server via a browser running on the server, but the service account still had NTLM errors when trying to authenticate for the web services. I wound up disabling the loop back check and that fixed it for me.
The simple way to do this is doing a div within a div
<div class="col-sm-4" style="padding: 5px;border:2px solid red;">_x000D_
<div class="server-action-menu" id="server_1">Server 1_x000D_
</div>_x000D_
</div>_x000D_
<div class="col-sm-4" style="padding: 5px;border:2px solid red;">_x000D_
<div class="server-action-menu" id="server_1">Server 2_x000D_
</div>_x000D_
</div>_x000D_
<div class="col-sm-4" style="padding: 5px;border:2px solid red;">_x000D_
<div class="server-action-menu" id="server_1">Server 3_x000D_
</div>_x000D_
</div>
_x000D_
It depends on the nature of your site.
I happen to work on a bit of software where IP tracking is important, and within a field consumed by parter sites I'd guess some 20% - 40% of requests are either detectably spoofed IPs or headers blanked out, depending on the time of day and where they came from. For a site which gets organic traffic (i.e. not through partners) I'd expect a much higher ratio of good IPs.
As Kosi said, be careful what you're doing with this - IPs are in no way a reliable way to identify unique visitors.
You wont be able to access a local resource from your aspx page (web server). Have you tried a relative path from your aspx page to your css file like so...
<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />
The above assumes that you have a folder called CSS
in the root of your website like this:
http://www.website.com/CSS/Style.css
Knowing the error message would be rather valuable. It is meant to provide info, even though it doesn't make any sense to you it does to us. Being forced to guess, I'd say that the DLL is a 32-bit DirectX filter. In which case this should be the proper course of action:
cd c:\windows\syswow64
move ..\system32\dllname.ax .
regsvr32.exe dllname.ax
This must be run at an elevated command prompt so that UAC cannot stop the registry access that's required. Ask more questions about this at superuser.com
It was changing the line endings (from Windows CRLF to Unix LF) in the .htaccess
file that fixed it for me.
The documentation of the file module says
If
state=file
, the file will NOT be created if it does not exist, see the copy or template module if you want that behavior.
So we use the copy module, using force=no
to create a new empty file only when the file does not yet exist (if the file exists, its content is preserved).
- name: ensure file exists
copy:
content: ""
dest: /etc/nologin
force: no
group: sys
owner: root
mode: 0555
This is a declarative and elegant solution.
To get the parameterized build params from the current build from your GroovyScript (using Pipeline), all you need to do is: Say you had a variable called VARNAME.
def myVariable = env.VARNAME
If you send a PHP array into a function that expects a string like: echo
or print
, then the PHP interpreter will convert your array to the literal string Array
, throw this Notice and keep going. For example:
php> print(array(1,2,3))
PHP Notice: Array to string conversion in
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(591) :
eval()'d code on line 1
Array
In this case, the function print
dumps the literal string: Array
to stdout and then logs the Notice to stderr and keeps going.
Another example in a PHP script:
<?php
$stuff = array(1,2,3);
print $stuff; //PHP Notice: Array to string conversion in yourfile on line 3
?>
$stuff = array(1,2,3);
foreach ($stuff as $value) {
echo $value, "\n";
}
Prints:
1
2
3
Or along with array keys
$stuff = array('name' => 'Joe', 'email' => '[email protected]');
foreach ($stuff as $key => $value) {
echo "$key: $value\n";
}
Prints:
name: Joe
email: [email protected]
Note that array elements could be arrays as well. In this case either use foreach
again or access this inner array elements using array syntax, e.g. $row['name']
In case it's just a plain 1-demensional array, you can simply join all the cells into a string using a delimiter:
<?php
$stuff = array(1,2,3);
print implode(", ", $stuff); //prints 1, 2, 3
print join(',', $stuff); //prints 1,2,3
In case your array has a complex structure but you need to convert it to a string anyway, then use http://php.net/json_encode
$stuff = array('name' => 'Joe', 'email' => '[email protected]');
print json_encode($stuff);
Prints
{"name":"Joe","email":"[email protected]"}
If you want just to inspect the array contents for the debugging purpose, use one of the following functions. Keep in mind that var_dump is most informative of them and thus usually being preferred for the purpose
examples
$stuff = array(1,2,3);
print_r($stuff);
$stuff = array(3,4,5);
var_dump($stuff);
Prints:
Array
(
[0] => 1
[1] => 2
[2] => 3
)
array(3) {
[0]=>
int(3)
[1]=>
int(4)
[2]=>
int(5)
}
these methods will help you-

Try:
$.ajax({
url: uri+'?js',
success: function(data) {
var imgAttr = $("img", data).attr('src');
var htmlCode = $(data).html();
$('#imgSrc').html(imgAttr);
$('#fullHtmlOutput').html(htmlCode);
}
});
This should load the whole html block from data into #fullHtmlOutput and the src of the image into #imgSrc.
Check out the documentation to see how decorators work. Here is what you asked for:
from functools import wraps
def makebold(fn):
@wraps(fn)
def wrapper(*args, **kwargs):
return "<b>" + fn(*args, **kwargs) + "</b>"
return wrapper
def makeitalic(fn):
@wraps(fn)
def wrapper(*args, **kwargs):
return "<i>" + fn(*args, **kwargs) + "</i>"
return wrapper
@makebold
@makeitalic
def hello():
return "hello world"
@makebold
@makeitalic
def log(s):
return s
print hello() # returns "<b><i>hello world</i></b>"
print hello.__name__ # with functools.wraps() this returns "hello"
print log('hello') # returns "<b><i>hello</i></b>"
The correct answer to this has already been given: no, you can't give the name of an enum, only it's value.
Nevertheless, just for fun, this will give you an enum and a lookup-table all in one and give you a means of printing it by name:
main.c:
#include "Enum.h"
CreateEnum(
EnumerationName,
ENUMValue1,
ENUMValue2,
ENUMValue3);
int main(void)
{
int i;
EnumerationName EnumInstance = ENUMValue1;
/* Prints "ENUMValue1" */
PrintEnumValue(EnumerationName, EnumInstance);
/* Prints:
* ENUMValue1
* ENUMValue2
* ENUMValue3
*/
for (i=0;i<3;i++)
{
PrintEnumValue(EnumerationName, i);
}
return 0;
}
Enum.h:
#include <stdio.h>
#include <string.h>
#ifdef NDEBUG
#define CreateEnum(name,...) \
typedef enum \
{ \
__VA_ARGS__ \
} name;
#define PrintEnumValue(name,value)
#else
#define CreateEnum(name,...) \
typedef enum \
{ \
__VA_ARGS__ \
} name; \
const char Lookup##name[] = \
#__VA_ARGS__;
#define PrintEnumValue(name, value) print_enum_value(Lookup##name, value)
void print_enum_value(const char *lookup, int value);
#endif
Enum.c
#include "Enum.h"
#ifndef NDEBUG
void print_enum_value(const char *lookup, int value)
{
char *lookup_copy;
int lookup_length;
char *pch;
lookup_length = strlen(lookup);
lookup_copy = malloc((1+lookup_length)*sizeof(char));
strcpy(lookup_copy, lookup);
pch = strtok(lookup_copy," ,");
while (pch != NULL)
{
if (value == 0)
{
printf("%s\n",pch);
break;
}
else
{
pch = strtok(NULL, " ,.-");
value--;
}
}
free(lookup_copy);
}
#endif

Take a look at JManage. It's able to execute MBean methods and get / set attributes from command line.
As of Bootstrap 3.x, there's an example of this in the docs here: http://getbootstrap.com/components/#input-groups-buttons-dropdowns

The answers here, are way too complex. Here's something I've recently used:
<?php global $product; ?>

Using wp_get_attachment_url()
to display the
def trim(x):
if x.dtype == object:

return(x)
df = df.apply(trim)
i have done a similar thing, think it might help u its actually working for me
int main(){ int co[8],i;char ch[8];printf("please enter the string:");scanf("%s",ch);for(i=0;i<=7;i++){if((ch[i]>='A')&&(ch[i]<='F')){co[i]=(unsigned int)ch[i]-'A'+10;}else if((ch[i]>='0')&&(ch[i]<='9')){co[i]=(unsigned int)ch[i]-'0'+0;}}
here i have only taken a string of 8 characters. if u want u can add similar logic for 'a' to 'f' to give their equivalent hex values,i haven't done that cause i didn't needed it.
There is a good explanation at https://stackoverflow.com/a/33833319/903783
The values expected seem to be xlCopy and xlCut according to xlCutCopyMode enumeration (https://msdn.microsoft.com/en-us/VBA/Excel-VBA/articles/xlcutcopymode-enumeration-excel), but the 0 value (this is what False equals to in VBA) seems to be useful to clear Excel data put on the Clipboard.
I had something simular: I have an attribute picture in my model, this contains the location of the file in the Storage folder. The image must be returned base64 encoded
//Add extra attribute
protected $attributes = ['picture_data'];
//Make it available in the json response
protected $appends = ['picture_data'];
//implement the attribute
public function getPictureDataAttribute()
{
$file = Storage::get($this->picture);
$type = Storage::mimeType($this->picture);
return "data:" . $type . ";base64," . base64_encode($file);
}
1.Concatenate the string (space between each string)
Code Snippet :
<?php
$txt1 = "Sachin";
$txt2 = "Tendulkar";
$result = $txt1.$txt2 ;
echo $result. "\n";
?>
Output: SachinTendulkar
2.Concatenate the string where space exists
Code Snippet :
<?php
$txt1 = "Sachin";
$txt2 = "Tendulkar";
$result = $txt1." ".$txt2;
echo $result. "\n";
?>
Output : Sachin Tendulkar
- Concatenate the string using printf function.
Code Snippet :
<?php
$data1 = "Sachin";
$data2 = "Tendulkar";
printf("%s%s\n",$data1, $data2);
printf("%s %s\n",$data1, $data2);
?>
Output:
SachinTendulkar

For folks who are stumbling across Victor Stoddard's answer above in 2019, and become hopeful and doe eyed, note that:
a) Support for X-Content-Duration was removed in Firefox 41: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/41#HTTP
b) I think it was only supported in Firefox for .ogg audio and .ogv video, not for any other types.
c) I can't see that it was ever supported at all in Chrome, but that may just be a lack of research on my part. But its presence or absence seems to have no effect one way or another for webm or ogv videos as of today in Chrome 71.
d) I can't find anywhere where 'Content-Duration' replaced 'X-Content-Duration' for anything, I don't think 'X-Content-Duration' lived long enough for there to be a successor header name.
I think this means that, as of today if you want to serve webm or ogv containers that contain streams that don't know their duration (e.g. the output of an ffpeg pipe) to Chrome or FF, and you want them to be scrubbable in an HTML 5 video element, you are probably out of luck. Firefox 64.0 makes a half hearted attempt to make these scrubbable whether or not you serve via range requests, but it gets confused and throws up a spinning wheel until the stream is completely downloaded if you seek a few times more than it thinks is appropriate. Chrome doesn't even try, it just nopes out and won't let you scrub at all until the entire stream is finished playing.
FYI you dont have string datatype in C. Use array of characters to store the value and manipulate it. Change your variable c into an array of characters and use it inside a loop to get values.
char c[10];
int i=0;
while(i!=10)
{
c[i]=fgetc(fp);
i++;
}
The other way to do is to use pointers and allocate memory dynamically and assign values.
Because the number can be up to 15 digits, you'll need to cast to an 64 bit (8-byte) integer. Try this:
SELECT * FROM table
WHERE myint = mytext::int8
The ::
cast operator is historical but convenient. Postgres also conforms to the SQL standard syntax
myint = cast ( mytext as int8)
If you have literal text you want to compare with an int
, cast the int
to text:
SELECT * FROM table
WHERE myint::varchar(255) = mytext
In case you are getting 530 password incorrect

While Evan Carrol's answer is correct, please note that you need to install the postgresql contrib package in order for the CREATE EXTENSION command to work.
In Ubuntu 12.04 it would go like this:
sudo apt-get install postgresql-contrib
Restart the postgresql server:
sudo /etc/init.d/postgresql restart
All available extension are in:
/usr/share/postgresql/9.1/extension/
Now you can run the CREATE EXTENSION command.
You can raise a notice in Postgres
as follows:
raise notice 'Value: %', deletedContactId;
Read here
SELECT 12 * (YEAR(end_date) - YEAR(start_date)) +
((MONTH(end_date) - MONTH(start_date))) +
SIGN(DAY(end_date) / DAY(start_date));
This works fine for me on SQL SERVER 2000.
It is because Ajax is asynchronous, the success
or the error
function will be called later, when the server answer the client. So, just move parts depending on the result into your success function like that :
jQuery.ajax({
type:"post",
dataType:"json",
url: myAjax.ajaxurl,
data: {action: 'submit_data', info: info},
success: function(data) {
successmessage = 'Data was succesfully captured';
$("label#successmessage").text(successmessage);
},
error: function(data) {
successmessage = 'Error';
$("label#successmessage").text(successmessage);
},
});
$(":input").val('');
return false;
Use .prop()
instead and if we go with your code then compare like this:
Look at the example jsbin:
$("#news_list tr").click(function () {
var ele = $(this).find(':checkbox');
if ($(':checked').length) {
ele.prop('checked', false);
$(this).removeClass('admin_checked');
} else {
ele.prop('checked', true);
$(this).addClass('admin_checked');
}
});
Changes:
input
to :checkbox
.the length
of the checked checkboxes
.Use position:fixed
, as previously stated, IE6 doesn't recognize position:fixed
, but with some css magic you can get IE6 to behave:
html, body {
height: 100%;
overflow:auto;
}
body #fixedElement {
position:fixed !important;
position: absolute; /*ie6 */
bottom: 0;
}
The !important
flag makes it so you don't have to use a conditional comment for IE. This will have #fixedElement
use position:fixed
in all browsers but IE, and in IE
, position:absolute
will take effect with bottom:0
. This will simulate position:fixed
for IE6
This approach will work ONLY when the total duration is less than 24 hours:
var now = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";
moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")
// outputs: "00:39:30"
If you have 24 hours or more, the hours will reset to zero with the above approach, so it is not ideal.
If you want to get a valid response for durations of 24 hours or greater, then you'll have to do something like this instead:
var now = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";
var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = Math.floor(d.asHours()) + moment.utc(ms).format(":mm:ss");
// outputs: "48:39:30"
Note that I'm using the utc time as a shortcut. You could pull out d.minutes()
and d.seconds()
separately, but you would also have to zeropad them.
This is necessary because the ability to format a duration
objection is not currently in moment.js. It has been requested here. However, there is a third-party plugin called moment-duration-format that is specifically for this purpose:
var now = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";
var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = d.format("hh:mm:ss");
// outputs: "48:39:30"
l1 = [] #Empty list is given
l1 = tuple(l1) #Through the type casting method we can convert list into tuple
print(type(l1)) #Now this show class of tuple
Interestingly, a ComboBox with DropDownStyle=Simple has pretty much exactly the behaviour you are looking for, I think.
(If you reduce the height of the control to not show the list - and then by a couple of pixels more - there's no effective difference between the ComboBox and the TextBox.)
On Mac OS (or, likely, any BSD), the sed command parameters have to be slightly different. Try this:
#!/bin/sh
if git-rev-parse --verify HEAD >/dev/null 2>&1 ; then
against=HEAD
else
# Initial commit: diff against an empty tree object
against=4b825dc642cb6eb9a060e54bf8d69288fbee4904
fi
# Find files with trailing whitespace
for FILE in `exec git diff-index --check --cached $against -- | sed '/^[+-]/d' | sed -E 's/:[0-9]+:.*//' | uniq` ; do
# Fix them!
sed -i '' -E 's/[[:space:]]*$//' "$FILE"
git add "$FILE"
done
Save this file as .git/hooks/pre-commit
-- or look for the one that's already there, and paste the bottom chunk somewhere inside it. And remember to chmod a+x
it too.
Or for global use (via Git commit hooks - global settings) you can put it in $GIT_PREFIX/git-core/templates/hooks
(where GIT_PREFIX is /usr or /usr/local or /usr/share or /opt/local/share) and run git init
inside your existing repos.
According to git help init
:
Running git init in an existing repository is safe. It will not overwrite things that are already there. The primary reason for rerunning git init is to pick up newly added templates.
Adding this meta tag in PHP might help:

I usually use svn through a gui, either my IDE or a client. Because of that, I can never remember the codes when I do have to resort to the command line.

Adding on to the accepted answer. I ran into a similar problem and ended up using a user defined function that returned clob instead of varchar2. Here's my solution:
CREATE OR REPLACE TYPE temp_data FORCE AS OBJECT
(
temporary_data NVARCHAR2(4000)
)
/
CREATE OR REPLACE TYPE temp_data_table FORCE AS TABLE OF temp_data;
/
CREATE OR REPLACE FUNCTION my_agg_func (p_temp_data_table IN temp_data_table, p_delimiter IN NVARCHAR2)
RETURN CLOB IS
l_string CLOB;
BEGIN
FOR i IN p_temp_data_table.FIRST .. p_temp_data_table.LAST LOOP
IF i != p_temp_data_table.FIRST THEN
l_string := l_string || p_delimiter;
END IF;
l_string := l_string || p_temp_data_table(i).temporary_data;
END LOOP;
RETURN l_string;
END my_agg_func;
/
Now, instead of doing
LISTAGG(column_to_aggregate, '#any_delimiter#') WITHIN GROUP (ORDER BY column_to_order_by)
I have to do this
my_agg_func (
cast(
collect(
temp_data(column_to_aggregate)
order by column_to_order_by
) as temp_data_table
),
'#any_delimiter#'
)
With ES 6 arrow function
let someArray = [
{name:"Kristian", lines:"2,5,10"},
{name:"John", lines:"1,19,26,96"}

let arrayToRemove={name:"Kristian", lines:"2,5,10"};
someArray=someArray.filter((e)=>e.name !=arrayToRemove.name && e.lines!= arrayToRemove.lines)
Simply pass the sorted items from the dictionary to the plot()
function. concentration.items()
returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.
You can take advantage of list unpacking (with *
) to pass the sorted data directly to zip, and then again to pass it into plot()
:
import matplotlib.pyplot as plt
concentration = {
0: 0.19849878712984576,
5000: 0.093917341754771386,
10000: 0.075060643507712022,
20000: 0.06673074282575861,
30000: 0.057119318961966224,
50000: 0.046134834546203485,
100000: 0.032495766396631424,
200000: 0.018536317451599615,
500000: 0.0059499290585381479}
plt.plot(*zip(*sorted(concentration.items())))
plt.show()
sorted()
sorts tuples in the order of the tuple's items so you don't need to specify a key
function because the tuples returned by dict.item()
already begin with the key value.
If you want to concatenate int or floats to a string you must use this:
i = 123
a = "foobar"
s = a + str(i)

private makes the class accessible only to the class in which it is declared. If we make entire class private no one from outside can access the class and makes it useless.
Inner class can be made private because the outer class can access inner class where as it is not the case with if you make outer class private.
When you set a string variable, it doesn't save quotes of it, they are a part of its definition. so you don't need to use :1
Found solution:
In iOS9, ATS enforces best practices during network calls, including the use of HTTPS.
ATS prevents accidental disclosure, provides secure default behavior, and is easy to adopt. You should adopt ATS as soon as possible, regardless of whether you’re creating a new app or updating an existing one. If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible.
In beta 1, currently there is no way to define this in info.plist. Solution is to add it manually:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
Update1: This is a temporary workaround until you're ready to adopt iOS9 ATS support.
Update2: For more details please refer following link: http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/
Update3: If you are trying to connect to a host (YOURHOST.COM) that only has TLS 1.0
Add these to your app's Info.plist
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>YOURHOST.COM</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSTemporaryExceptionMinimumTLSVersion</key>
<string>1.0</string>
<key>NSTemporaryExceptionRequiresForwardSecrecy</key>
<false/>

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;
as Name = Fname + " " + LName;
See my below code which is working as expected; hope this is useful;
Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}
no need to declare the 'contact'
Given the Class loader sussystem actions:
This is an article that helped me a lot to understand the difference: http://docs.oracle.com/javase/specs/jvms/se7/html/jvms-5.html
If an error occurs during class loading, then an instance of a subclass of LinkageError must be thrown at a point in the program that (directly or indirectly) uses the class or interface being loaded.
If the Java Virtual Machine ever attempts to load a class C during verification (§5.4.1) or resolution (§5.4.3) (but not initialization (§5.5)), and the class loader that is used to initiate loading of C throws an instance of ClassNotFoundException, then the Java Virtual Machine must throw an instance of NoClassDefFoundError whose cause is the instance of ClassNotFoundException.
So a ClassNotFoundException is a root cause of NoClassDefFoundError.
And a NoClassDefFoundError is a special case of type loading error, that occurs at Linking step.
You can do something like this.
$a = start-process -NoNewWindow powershell {timeout 10; 'done'} -PassThru
And if you want to wait for it:
$a | wait-process
Bonus osx or linux version:
$a = start-process pwsh '-c',{start-sleep 5; 'done'} -PassThru
Example pinger script I have. The args are passed as an array:
$1 = start -n powershell pinger,comp001 -pa

Adding this late answer to show a case most people will come across. If you only need to see what is the last item in the list, use the last
key word:
<div *ngFor="let item of devcaseFeedback.reviewItems; let last = last">
<divider *ngIf="!last"></divider>
</div>
This will add the divider component to every item except the last.
Because of the comment below, I will add the rest of the ngFor
exported values that can be aliased to local variables (As are shown in the docs):
Try this one for current selection:
Sub A_SelectAllMakeTable2()
Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
or equivalent of your macro (for Ctrl+Shift+End range selection):
Sub A_SelectAllMakeTable()
Dim tbl As ListObject
Dim rng As Range
Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
Most of previous answers call the success of the promise in the on("data"), it is not the proper way to do it because if you receive a lot of data you will only get the first part. Instead you have to do it on the end event.

const python = pythonDir + "pythonEnv/bin/python"; // Path of the Python interpreter

const pyprog = spawn(python, pyArgs );
let result = "";
let resultError = "";
pyprog.stdout.on('data', function(data) {

pyprog.stderr.on('data', (data) => {
resultError += cleanWarning(data.toString());

success(JSON.parse(result));
}else{
console.error(`Python error, you can reproduce the error with: \n${python} ${script} ${pyArgs.join(" ")}`);

console.error(error);
reject(resultError);

If you go through the documentation, they have mentioned to use php composer.phar
Link: https://getcomposer.org/doc/03-cli.md#update-u
Don't use php composer.phar
only give composer

It will work.

There is an option in the Virtual Box itself. If you look in the Oracle VM Virtual Box Manager. Select the Virtual Box you want to start. Go to System, the second from above item in the right pane. In System go to the third tab called acceleration. In that tab the first check box is called something like: 'VT-x/AMD-V' (I have the Dutch version, so I don't know the exact string) UNCHECK And then start. That worked for me.
I also got this problem after an upgrade. And I did not have the problem before. But I fail to see the exact connection between the update and the check/unchecking of that option.
By the way, I have no idea where the hell that 'virtualization tab' should be in my 'BIOS'. Maybe I was looking in my PC's BIOS not the System page here which is the BIOS of the VM Machine maybe and that is what you meant Veer7? If it was, it was pretty unclear you meant this. Maybe it's because I have OVM in Dutch not English. But there was nothing called BIOS in the Oracle VM Virtual Box Manager I could find.
In my case it was - no disk space left on the web server.
As most of browsers has been updated, So print and close do not any more as It worked before. So you should add onafterprint event listener in order to close print window.
var printWindow = window.open('https://stackoverflow.com/');
printWindow.print();
//Close window once print is finished
printWindow.onafterprint = function(){
printWindow.close()
};
The DateTime.Ticks
property gets the number of ticks that represent the date and time.
10,000 Ticks is a millisecond (10,000,000 ticks per second).
As an addition, you can also mix different ways of usage when calling kwargs functions:
def test(**kwargs):
print kwargs['a']
print kwargs['b']
print kwargs['c']
args = { 'b': 2, 'c': 3}
test( a=1, **args )
gives this output:
1
2
3
Note that **kwargs has to be the last argument
@Wardenclyffe and @SColvin, you both are trying to save image using the canvas, not by using canvas's context. both you should try to ctx.toDataURL(); Try This:
var canvas1 = document.getElementById("yourCanvasId"); <br>
var ctx = canvas1.getContext("2d");<br>
var img = new Image();<br>
img.src = ctx.toDataURL('image/png');<br>
ctx.drawImage(img,200,150);<br>

The network is always unpredictable. TCP makes a lot of this random behavior go away for you. One wonderful thing TCP does: it guarantees that the bytes will arrive in the same order. But! It does not guarantee that they will arrive chopped up in the same way. You simply cannot assume that every send() from one end of the connection will result in exactly one recv() on the far end with exactly the same number of bytes.
When you say socket.recv(x)
, you're saying 'don't return until you've read x bytes from the socket'. This is called "blocking I/O": you will block (wait) until your request has been filled. If every message in your protocol was exactly 1024 bytes, calling socket.recv(1024)
would work great. But it sounds like that's not true. If your messages are a fixed number of bytes, just pass that number in to socket.recv()
and you're done.
But what if your messages can be of different lengths? The first thing you need to do: stop calling socket.recv()
with an explicit number. Changing this:
data = self.request.recv(1024)
to this:
data = self.request.recv()
means recv()
will always return whenever it gets new data.
But now you have a new problem: how do you know when the sender has sent you a complete message? The answer is: you don't. You're going to have to make the length of the message an explicit part of your protocol. Here's the best way: prefix every message with a length, either as a fixed-size integer (converted to network byte order using socket.ntohs()
or socket.ntohl()
please!) or as a string followed by some delimiter (like '123:'). This second approach often less efficient, but it's easier in Python.
Once you've added that to your protocol, you need to change your code to handle recv()
returning arbitrary amounts of data at any time. Here's an example of how to do this. I tried writing it as pseudo-code, or with comments to tell you what to do, but it wasn't very clear. So I've written it explicitly using the length prefix as a string of digits terminated by a colon. Here you go:
length = None
buffer = ""
while True:
data += self.request.recv()
if not data:
break
buffer += data
while True:
if length is None:
if ':' not in buffer:
break
# remove the length bytes from the front of buffer
# leave any remaining bytes in the buffer!
length_str, ignored, buffer = buffer.partition(':')
length = int(length_str)
if len(buffer) < length:
break
# split off the full message from the remaining bytes
# leave any remaining bytes in the buffer!
message = buffer[:length]
buffer = buffer[length:]
length = None
# PROCESS MESSAGE HERE
Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'
. Next the unit of the current zoom is calculated, it could be one of:
This unit is then used find a format for the axis labels. The default patterns are:
second: '%H:%M:%S',
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'
If you want the day to be part of the "hour"-level labels you should change the dateTimeLabelFormats
option for that level include %d
or %e
.
These are the available patters:
http://api.highcharts.com/highcharts#xAxis.dateTimeLabelFormats
For All variable ALT+SHIFT+S Then R and for select all Press ALT+A
For Single variable Point cursor on the variable then press CTRL+1 and go for the second option from suggestions
Use some regex like [0-9]
or \d
:
$words = preg_replace('/\d+/', '', $words );
You might want to read the preg_replace() documentation as this is directly shown there.
This line looks questionable:
page_output.innerHTML = str_output;
You can use .innerHTML
within jQuery, or you can use it without, but you have to address the selector semantically one way or the other:
$('#page_output').innerHTML /* for jQuery */
document.getElementByID('page_output').innerHTML /* for standard JS */
or better yet
$('#page_output').html(str_output);
Partial Dependency is one kind of functional dependency that occur when primary key must be candidate key and non prime attribute are depends on the subset/part of candidates key (more than one primary key).
Try to understand partial dependency relate through example :
Seller(Id, Product, Price)
Candidate Key : Id, Product
Non prime attribute : Price
Price attribute only depends on only Product attribute which is a subset of candidate key, Not the whole candidate key(Id, Product) key . It is called partial dependency.
So we can say that Product->Price is partial dependency.
UPDATE
Angular offers now the two scope methods $watchGroup (since 1.3) and $watchCollection. Those have been mentioned by @blazemonger and @kargold.
This should work independent of the types and values:
$scope.$watch('[age,name]', function () { ... }, true);
You have to set the third parameter to true in this case.
The string concatenation 'age + name'
will fail in a case like this:
<button ng-init="age=42;name='foo'" ng-click="age=4;name='2foo'">click</button>
Before the user clicks the button the watched value would be 42foo
(42
+ foo
) and after the click 42foo
(4
+ 2foo
). So the watch function would not be called. So better use an array expression if you cannot ensure, that such a case will not appear.

Thanks to this post, I found an easier answer:
Open Sql Server Management Studio
Go to object Explorer -> Security -> Logins
Right click on the login and select properties
And in the properties window change the default database and click OK.
In Swift you can do like this
let number : NSNumber = 95
let str : String = number.stringValue
to keep it simple: EOF is an integer type with value -1. Therefore, we must use an integer variable to test EOF.
For finding value use below
if let a = companies["AAPL"] {
// a is the value
}
For traversing through the dictionary
for (key, value) in companies {
print(key,"---", value)
}
Finally for searching key by value you firstly add the extension
extension Dictionary where Value: Equatable {
func findKey(forValue val: Value) -> Key? {
return first(where: { $1 == val })?.key
}
}
Then just call
companies.findKey(val : "Apple Inc")
128 characters. This is the max length of the sysname
datatype (nvarchar(128)
).
I see this nice tutorial on how to get the like count from facebook using PHP.

$component = urlencode( $params );
$url = 'http://graph.facebook.com/fql?q='.$component;
$fbLIkeAndSahre = json_decode( $this->file_get_content_curl( $url ) );
$getFbStatus = $fbLIkeAndSahre->data['0'];
return $getFbStatus->like_count;
}
here is a sample code.. I don't know how to paste the code with correct format in here, so just kindly visit this link for better view of the code.

If your textfile manipulation usually is one-time, possibly done on the shell-prompt, you will not get anything better from python.
On the other hand, if you usually have to do the same (or similar) task over and over, and you have to write your scripts for doing that, then python is great - and you can easily create your own libraries (you can do that with shell scripts too, but it's more cumbersome).
A very simple example to get a feeling.
import popen2
stdout_text, stdin_text=popen2.popen2("your-shell-command-here")
for line in stdout_text:
if line.startswith("#"):
pass
else
jobID=int(line.split(",")[0].split()[1].lstrip("<").rstrip(">"))
# do something with jobID
Check also sys and getopt module, they are the first you will need.

In the manual for GNU make, they talk about this specific example when describing the value
function:
The value function provides a way for you to use the value of a variable without having it expanded. Please note that this does not undo expansions which have already occurred; for example if you create a simply expanded variable its value is expanded during the definition; in that case the value function will return the same result as using the variable directly.
The syntax of the value function is:
$(value variable)
Note that variable is the name of a variable; not a reference to that variable. Therefore you would not normally use a ‘$’ or parentheses when writing it. (You can, however, use a variable reference in the name if you want the name not to be a constant.)
The result of this function is a string containing the value of variable, without any expansion occurring. For example, in this makefile:
FOO = $PATH all: @echo $(FOO) @echo $(value FOO)
The first output line would be ATH, since the “$P” would be expanded as a make variable, while the second output line would be the current value of your $PATH environment variable, since the value function avoided the expansion.
We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration. -- jQuery.each() | jQuery API Documentation
This one works with NULL Values in Table and doesn't require substring operation at the end. COALESCE is not really well working with NULL values in table (if they will be there).
DECLARE @results VARCHAR(1000) = ''
SELECT @results = @results +
ISNULL(CASE WHEN LEN(@results) = 0 THEN '' ELSE ',' END + [StudentId], '')
FROM Student WHERE condition = xyz
select @results
You can manually iterate over the elements of the set:
Iterator<Integer> iterator = set.iterator();
while (iterator.hasNext()) {
Integer element = iterator.next();
if (element % 2 == 0) {
iterator.remove();
}
}
You will often see this pattern using a for
loop rather than a while
loop:
for (Iterator<Integer> i = set.iterator(); i.hasNext();) {
Integer element = i.next();
if (element % 2 == 0) {
i.remove();
}
}
As people have pointed out, using a for
loop is preferred because it keeps the iterator variable (i
in this case) confined to a smaller scope.

As in a similar question, use display: inline-block
with a placeholder element to vertically center the span inside of a block element:
html, body, #container, #placeholder { height: 100%; }_x000D_
_x000D_
#content, #placeholder { display:inline-block; vertical-align: middle; }
_x000D_
<!doctype html>_x000D_
<html lang="en">_x000D_
<head>_x000D_
</head>_x000D_
_x000D_
<body>_x000D_
<div id="container">_x000D_
<span id="content">_x000D_
Content_x000D_
</span>_x000D_
<span id="placeholder"></span>_x000D_
</div>_x000D_
</body>_x000D_
</html>
_x000D_
Vertical alignment is only applied to inline elements or table cells, so use it along with display:inline-block
or display:table-cell
with a display:table
parent when vertically centering block elements.

<%= f.submit 'name of button here', :class => 'submit_class_name_here' %>
This should do. If you're getting an error, chances are that you're not supplying the name.
Alternatively, you can style the button without a class:
form#form_id_here input[type=submit]
Try that, as well.
Use selectors like CSS3
$("banner.html>div:first-child").append(data);
To center align text
input[type='text'] { text-align:center;}
To center align the textbox in the container that it sits in, apply text-align:center to the container.
Several people have recommended adding a null check. Sometimes that's the right thing to do, but not always. Check out this excellent article showing why you'd skip it.

step 1.to send data from fragment to activity
Intent intent = new Intent(getActivity().getBaseContext(),
TargetActivity.class);
intent.putExtra("message", message);
getActivity().startActivity(intent);
step 2.to receive this data in Activity:
Intent intent = getIntent();
String message = intent.getStringExtra("message");
step 3. to send data from activity to another activity follow normal approach
Intent intent = new Intent(MainActivity.this,
TargetActivity.class);
intent.putExtra("message", message);
startActivity(intent);
step 4 to receive this data in activity
Intent intent = getIntent();
String message = intent.getStringExtra("message");
Step 5. From Activity you can send data to Fragment with intent as:
Bundle bundle=new Bundle();
bundle.putString("message", "From Activity");
//set Fragmentclass Arguments
Fragmentclass fragobj=new Fragmentclass();
fragobj.setArguments(bundle);
and to receive in fragment in Fragment onCreateView method:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String strtext=getArguments().getString("message");
return inflater.inflate(R.layout.fragment, container, false);
}
The easiest way to match both
^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$
and
^[0-9]{3}-[0-9]{3}-[0-9]{4}$
is to use alternation ((...|...)
): specify them as two mostly-separate options:
^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$
By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234
, not (123)123-1234
. So you might want to write:
^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$
(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)
Use the CSS3 Viewport-percentage feature.
Viewport-Percentage Explanation
Assuming you want the body width size to be a ratio of the browser's view port. I added a border so you can see the body resize as you change your browser width or height. I used a ratio of 90% of the view-port size.

For me it was another problem. This might be trivial for some, but it took me a while to figure out. So this answer might be helpfull to some.
I had my API_BASE_URL
set to localhost:58577
. The coin dropped after reading the error message for the millionth time. The problem is in the part where it says that it only supports HTTP
and some other protocols. I had to change the API_BASE_URL
so that it includes the protocol. So changing API_BASE_URL
to http://localhost:58577
it worked perfectly.
From git reset
"pull" or "merge" always leaves the original tip of the current branch in
ORIG_HEAD
.git reset --hard ORIG_HEAD
Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.
git reset --merge ORIG_HEAD
After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "
git reset --hard ORIG_HEAD
" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge
" keeps your local changes.
Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am
' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).In addition, merge always sets '
.git/ORIG_HEAD
' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD
'.
Note: from here
HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.
So HEAD is NOT a synonym for "current branch" everywhere already.
HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).
But it almost always means the "current commit".
It is the commit "git commit
" builds on top of, and "git diff --cached
" and "git status
" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".
HEAD@{5.minutes.ago}
could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".
git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.
Instead of typing four capital letters "
HEAD
", you can say "@
" now,
e.g. "git log @
".
See commit cdfd948
Typing '
HEAD
' is tedious, especially when we can use '@
' instead.The reason for choosing '
@
' is that it follows naturally from theref@op
syntax (e.g.HEAD@{u}
), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD
'.So now we can use '
git show @~1
', and all that goody goodness.Until now '
@
' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.
From the documentation:
list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, soa.insert(0, x)
inserts at the front of the list, anda.insert(len(a),x)
is equivalent toa.append(x)
http://docs.python.org/2/tutorial/datastructures.html#more-on-lists
In modern browsers (IE8, Firefox, Chrome, Opera, Safari) you can use querySelector()
:
function test(el){
el.querySelector("#child").style.display = "none";
}
For older browsers (<=IE7), you would have to use some sort of library, such as Sizzle or a framework, such as jQuery, to work with selectors.
As mentioned, IDs are supposed to be unique within a document, so it's easiest to just use document.getElementById("child")
.
This is how I did a similar thing. I have tiles that are thumbnails to YouTube videos. When I click the tile, it redirects me to a 'player' page that uses the 'video_id' to render the correct video to the page.
<GridTile
key={video_id}
title={video_title}
containerElement={<Link to={`/player/${video_id}`}/>}
>
ETA: Sorry, just noticed that you didn't want to use the LINK or REDIRECT components for some reason. Maybe my answer will still help in some way. ; )
You should use the -x
command line argument which excludes any task.
Try:
gradle build -x test
Update:
The link in Peter's comment changed. Here is the diagram from the Gradle user's guide
The Path class is very useful here.
You get two methods called
that could solve your issue
So for example you could write: (if you don't mind the exact file name)
using(StreamWriter sw = new StreamWriter(Path.GetTempFileName()))
{
sw.WriteLine("Your error message");
}
Or if you need to set your file name
string myTempFile = Path.Combine(Path.GetTempPath(), "SaveFile.txt");
using(StreamWriter sw = new StreamWriter(myTempFile))
{
sw.WriteLine("Your error message");
}
You can also use joblib.dump and joblib.load which is much more efficient at handling numerical arrays than the default python pickler.
Joblib is included in scikit-learn:
>>> import joblib
>>> from sklearn.datasets import load_digits
>>> from sklearn.linear_model import SGDClassifier
>>> digits = load_digits()
>>> clf = SGDClassifier().fit(digits.data, digits.target)
>>> clf.score(digits.data, digits.target) # evaluate training error
0.9526989426822482
>>> filename = '/tmp/digits_classifier.joblib.pkl'
>>> _ = joblib.dump(clf, filename, compress=9)
>>> clf2 = joblib.load(filename)
>>> clf2
SGDClassifier(alpha=0.0001, class_weight=None, epsilon=0.1, eta0=0.0,
fit_intercept=True, learning_rate='optimal', loss='hinge', n_iter=5,
n_jobs=1, penalty='l2', power_t=0.5, rho=0.85, seed=0,
shuffle=False, verbose=0, warm_start=False)
>>> clf2.score(digits.data, digits.target)
0.9526989426822482
Edit: in Python 3.8+ it's now possible to use pickle for efficient pickling of object with large numerical arrays as attributes if you use pickle protocol 5 (which is not the default).
Perhaps this will work?
<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
<c:set var="myVar" value="${stat.first ? '' : myVar} ${currentItem}" />
</c:forEach>

Same as AMIB answer, for soft delete error "Unknown column 'table_alias.deleted_at'",
just add ->withTrashed()
then handle it yourself like ->whereRaw('items_alias.deleted_at IS NULL')
header('Content-type: image/jpeg');

It seem that w3c switched it to font/woff2
I see there is some discussion about the proper mime type. In the link we read:
This document defines a top-level MIME type "font" ...
... the officially defined IANA subtypes such as "application/font-woff" ...
The members of the W3C WebFonts WG believe the use of "application" top-level type is not ideal.
and later
6.5. WOFF 2.0
Type name:
font
Subtype name:
woff2
So proposition from W3C differs from IANA.
We can see that it also differs from woff type: http://dev.w3.org/webfonts/WOFF/spec/#IMT where we read:
Type name:
application
Subtype name:
font-woff
which is
application/font-woff
I haven't seen this done before, but this is how it was done for emulating IE 8/7 when using IE 9:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">
If not, then try this one:
<meta http-equiv="X-UA-Compatible" content="IE=9">
Add those to your header with the other meta tags. This should force IE10 to render as IE9.
Another option you could do (assuming you are using PHP) is add this to your .htaccess
file:
Header set X-UA-Compatible "IE=9"
This will perform the action universally, rather than having to worry about adding the meta tag to all of your headers.
The only difference is that CHARACTER VARYING is more human friendly than VARCHAR
I was trying to work with that solutions but it doesn't work. But later I was realize that the function it wasn't declared so I watch in to the dropzone.com page and take the example to call events. So finally work on my site. For those like me who don't understand JavaScript very well, I leave you the example.
<script type="text/javascript" src="/js/dropzone.js"></script>
<script type="text/javascript">
// This example uses jQuery so it creates the Dropzone, only when the DOM has
// loaded.
// Disabling autoDiscover, otherwise Dropzone will try to attach twice.
Dropzone.autoDiscover = false;
// or disable for specific dropzone:
// Dropzone.options.myDropzone = false;
$(function() {
// Now that the DOM is fully loaded, create the dropzone, and setup the
// event listeners
var myDropzone = new Dropzone(".dropzone");
myDropzone.on("queuecomplete", function(file, res) {
if (myDropzone.files[0].status != Dropzone.SUCCESS ) {
alert('yea baby');
} else {
alert('cry baby');
}
});
});
</script>
Try this query. Its very easy to understand:
CREATE TABLE PersonsDetail(FirstName nvarchar(20), LastName nvarchar(20), GenderID int);
GO
INSERT INTO PersonsDetail VALUES(N'Gourav', N'Bhatia', 2),
(N'Ramesh', N'Kumar', 1),
(N'Ram', N'Lal', 2),
(N'Sunil', N'Kumar', 3),
(N'Sunny', N'Sehgal', 1),
(N'Malkeet', N'Shaoul', 3),
(N'Jassy', N'Sohal', 2);
GO
SELECT FirstName, LastName, Gender =
CASE GenderID
WHEN 1 THEN 'Male'
WHEN 2 THEN 'Female'
ELSE 'Unknown'
END
FROM PersonsDetail
Seems like the problem is with the date format.
var d = "17-09-2013 10:08",
dArr = d.split('-'),
ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000
The runtime splits the arguments given at the console at each space.
If you call
myApp.exe arg1 arg2 arg3
The Main Method gets an array of
var args = new string[] {"arg1","arg2","arg3"}
I think the docs explain the difference and usage of these two functions pretty well:
Creates a thread pool that reuses a fixed number of threads operating off a shared unbounded queue. At any point, at most nThreads threads will be active processing tasks. If additional tasks are submitted when all threads are active, they will wait in the queue until a thread is available. If any thread terminates due to a failure during execution prior to shutdown, a new one will take its place if needed to execute subsequent tasks. The threads in the pool will exist until it is explicitly shutdown.
Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available. These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks. Calls to execute will reuse previously constructed threads if available. If no existing thread is available, a new thread will be created and added to the pool. Threads that have not been used for sixty seconds are terminated and removed from the cache. Thus, a pool that remains idle for long enough will not consume any resources. Note that pools with similar properties but different details (for example, timeout parameters) may be created using ThreadPoolExecutor constructors.
In terms of resources, the newFixedThreadPool
will keep all the threads running until they are explicitly terminated. In the newCachedThreadPool
Threads that have not been used for sixty seconds are terminated and removed from the cache.
Given this, the resource consumption will depend very much in the situation. For instance, If you have a huge number of long running tasks I would suggest the FixedThreadPool
. As for the CachedThreadPool
, the docs say that "These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks".
from PIL import Image
image_file = Image.open("convert_image.png") # open colour image
image_file = image_file.convert('1') # convert image to black and white
image_file.save('result.png')
yields
There are two ways to fix this:
Execute the following in the MySQL console:
SET GLOBAL log_bin_trust_function_creators = 1;
Add the following to the mysql.ini configuration file:
log_bin_trust_function_creators = 1;
The setting relaxes the checking for non-deterministic functions. Non-deterministic functions are functions that modify data (i.e. have update, insert or delete statement(s)). For more info, see here.
Please note, if binary logging is NOT enabled, this setting does not apply.
Binary Logging of Stored Programs
If binary logging is not enabled, log_bin_trust_function_creators does not apply.
log_bin_trust_function_creators
This variable applies when binary logging is enabled.
The best approach is a better understanding and use of deterministic declarations for stored functions. These declarations are used by MySQL to optimize the replication and it is a good thing to choose them carefully to have a healthy replication.
DETERMINISTIC A routine is considered “deterministic” if it always produces the same result for the same input parameters and NOT DETERMINISTIC otherwise. This is mostly used with string or math processing, but not limited to that.
NOT DETERMINISTIC Opposite of "DETERMINISTIC". "If neither DETERMINISTIC nor NOT DETERMINISTIC is given in the routine definition, the default is NOT DETERMINISTIC. To declare that a function is deterministic, you must specify DETERMINISTIC explicitly.". So it seems that if no statement is made, MySQl will treat the function as "NOT DETERMINISTIC". This statement from manual is in contradiction with other statement from another area of manual which tells that: " When you create a stored function, you must declare either that it is deterministic or that it does not modify data. Otherwise, it may be unsafe for data recovery or replication. By default, for a CREATE FUNCTION statement to be accepted, at least one of DETERMINISTIC, NO SQL, or READS SQL DATA must be specified explicitly. Otherwise an error occurs"
I personally got error in MySQL 5.5 if there is no declaration, so i always put at least one declaration of "DETERMINISTIC", "NOT DETERMINISTIC", "NO SQL" or "READS SQL DATA" regardless other declarations i may have.
READS SQL DATA This explicitly tells to MySQL that the function will ONLY read data from databases, thus, it does not contain instructions that modify data, but it contains SQL instructions that read data (e.q. SELECT).
MODIFIES SQL DATA This indicates that the routine contains statements that may write data (for example, it contain UPDATE, INSERT, DELETE or ALTER instructions).
NO SQL This indicates that the routine contains no SQL statements.
CONTAINS SQL This indicates that the routine contains SQL instructions, but does not contain statements that read or write data. This is the default if none of these characteristics is given explicitly. Examples of such statements are SELECT NOW(), SELECT 10+@b, SET @x = 1 or DO RELEASE_LOCK('abc'), which execute but neither read nor write data.
Note that there are MySQL functions that are not deterministic safe, such as: NOW(), UUID(), etc, which are likely to produce different results on different machines, so a user function that contains such instructions must be declared as NOT DETERMINISTIC. Also, a function that reads data from an unreplicated schema is clearly NONDETERMINISTIC. *
Assessment of the nature of a routine is based on the “honesty” of the creator: MySQL does not check that a routine declared DETERMINISTIC is free of statements that produce nondeterministic results. However, misdeclaring a routine might affect results or affect performance. Declaring a nondeterministic routine as DETERMINISTIC might lead to unexpected results by causing the optimizer to make incorrect execution plan choices. Declaring a deterministic routine as NONDETERMINISTIC might diminish performance by causing available optimizations not to be used.
Yeah, you need to grab the result of matcher.replaceAll()
:
String result = matcher.replaceAll(" ");
System.out.println(result);
First, describe nodes and see if it reports anything:
$ kubectl describe nodes
Look for conditions, capacity and allocatable:
Conditions:
Type Status
---- ------
OutOfDisk False
MemoryPressure False
DiskPressure False
Ready True
Capacity:
cpu: 2
memory: 2052588Ki
pods: 110
Allocatable:
cpu: 2
memory: 1950188Ki
pods: 110
If everything is alright here, SSH into the node and observe kubelet
logs to see if it reports anything. Like certificate erros, authentication errors etc.
If kubelet
is running as a systemd service, you can use
$ journalctl -u kubelet
If the class implements the method directly, it will not use the traits version. Perhaps what you are thinking of is:
trait A {
function calc($v) {
return $v+1;
}
}
class MyClass {
function calc($v) {
return $v+2;
}
}
class MyChildClass extends MyClass{
}
class MyTraitChildClass extends MyClass{
use A;
}
print (new MyChildClass())->calc(2); // will print 4
print (new MyTraitChildClass())->calc(2); // will print 3
Because the child classes do not implement the method directly, they will first use that of the trait if there otherwise use that of the parent class.
If you want, the trait can use method in the parent class (assuming you know the method would be there) e.g.
trait A {
function calc($v) {
return parent::calc($v*3);
}
}
// .... other code from above
print (new MyTraitChildClass())->calc(2); // will print 8 (2*3 + 2)
You can also provide for ways to override, but still access the trait method as follows:
trait A {
function trait_calc($v) {
return $v*3;
}
}
class MyClass {
function calc($v) {
return $v+2;
}
}
class MyTraitChildClass extends MyClass{
use A {
A::trait_calc as calc;
}
}
class MySecondTraitChildClass extends MyClass{
use A {
A::trait_calc as calc;
}
public function calc($v) {
return $this->trait_calc($v)+.5;
}
}
print (new MyTraitChildClass())->calc(2); // will print 6
echo "\n";
print (new MySecondTraitChildClass())->calc(2); // will print 6.5

I have faced this issue in TextView. I have tried
android:textAllCaps="false",
mbutton.setAllCaps(false);
<item name="android:textAllCaps">false</item>
none of that worked for me. Finally I fed up and I have hard coded text, it is working.
tv.setText("Mytext");
tv is object of TextView. But as per coding standards, it is bad practice.
```javascript
{ "some": "json" }
```
I tried using json
but didn't like the way it looked. javascript
looks a bit more pleasing to my eye.
Before Mongo 3.6:
You may start mongodb with
mongod --httpinterface
And access it on
http://localhost:28017
Since version 2.6: MongoDB disables the HTTP interface by default.
Update
HTTP Interface and REST API
MongoDB 3.6 removes the deprecated HTTP interface and REST API to MongoDB.
The simple way to use XMLHttpRequest
with pure JavaScript
. You can set custom header
but it's optional used based on requirement.
window.onload = function(){
var request = new XMLHttpRequest();
var params = "UID=CORS&name=CORS";
request.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(this.responseText);
}
};
request.open('POST', 'https://www.example.com/api/createUser', true);
request.setRequestHeader('api-key', 'your-api-key');
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
request.send(params);
}
You can send params using POST method.
Please run below example and will get an JSON response.
window.onload = function(){_x000D_
var request = new XMLHttpRequest();_x000D_
_x000D_
request.onreadystatechange = function() {_x000D_
if (this.readyState == 4 && this.status == 200) {_x000D_
console.log(this.responseText);_x000D_
}_x000D_
};_x000D_
_x000D_
request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
request.send();_x000D_
}
_x000D_
Better yet:
for i in xa*; do
sed -i 's/asd/dfg/g' $i
done
because nobody knows how many files are there, and it's easy to break command line limits.
Here's what happens when there are too many files:
# grep -c aaa *
-bash: /bin/grep: Argument list too long
# for i in *; do grep -c aaa $i; done
0
... (output skipped)
#
Could this be a typo? (two Ps in ppasscode, intended?)
$_POST['ppasscode'];
I would make sure and do:
print_r($_POST);
and make sure the data is accurate there, and then echo out what it should look like:
echo hash('sha256', $_POST['ppasscode']);
Compare this output to what you have in the database (manually). By doing this you're exploring your possible points of failure:
For the particular case of Windows 10 October 2018 Update or later activedirectory
module is not available unless the optional feature RSAT: Active Directory Domain Services and Lightweight Directory Services Tools
is installed (instructions here + uncollapse install instructions).
Reopen Windows Powershell and import-module activedirectory
will work as expected.
What I've always done is just wrap the radio button inside the label...
<label for="one">
<input type="radio" id="one" name="first_item" value="1" />
First Item
</label>
Something like that, has always worked for me.
img.UriSource = new Uri("pack://application:,,,/images/" + fileName, UriKind.Absolute);
Having requirements in requirements.txt
and egg_dir
as a directory
you can build your local cache:
$ pip download -r requirements.txt -d eggs_dir
then, using that "cache" is simple like:
$ pip install -r requirements.txt --find-links=eggs_dir
To show the commits in oldbranch but not in newbranch:
git log newbranch..oldbranch

Something like this lets you test your procedure on almost any client:
DECLARE
v_cur SYS_REFCURSOR;
v_a VARCHAR2(10);
v_b VARCHAR2(10);
BEGIN
your_proc(v_cur);
LOOP
FETCH v_cur INTO v_a, v_b;
EXIT WHEN v_cur%NOTFOUND;
dbms_output.put_line(v_a || ' ' || v_b);
END LOOP;
CLOSE v_cur;
END;
Basically, your test harness needs to support the definition of a SYS_REFCURSOR
variable and the ability to call your procedure while passing in the variable you defined, then loop through the cursor result set. PL/SQL does all that, and anonymous blocks are easy to set up and maintain, fairly adaptable, and quite readable to anyone who works with PL/SQL.
Another, albeit similar way would be to build a named procedure that does the same thing, and assuming the client has a debugger (like SQL Developer, PL/SQL Developer, TOAD, etc.) you could then step through the execution.
For a Windows machine start the mongod
process by specifying the dbpath:
mongod --dbpath \mongodb\data

I suppose rgba()
would work here. After all, browser support for both box-shadow
and rgba()
is roughly the same.
/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);
