It has ability to convert HTML file in to pdf.
Required namespace for conversions are:
using iTextSharp.text;
using iTextSharp.text.pdf;
and for conversion and download file :
// Create a byte array that will eventually hold our final PDF
Byte[] bytes;
// Boilerplate iTextSharp setup here
// Create a stream that we can write to, in this case a MemoryStream
using (var ms = new MemoryStream())
{
// Create an iTextSharp Document which is an abstraction of a PDF but **NOT** a PDF
using (var doc = new Document())
{
// Create a writer that's bound to our PDF abstraction and our stream
using (var writer = PdfWriter.GetInstance(doc, ms))
{
// Open the document for writing
doc.Open();
string finalHtml = string.Empty;
// Read your html by database or file here and store it into finalHtml e.g. a string
// XMLWorker also reads from a TextReader and not directly from a string
using (var srHtml = new StringReader(finalHtml))
{
// Parse the HTML
iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml);
}
doc.Close();
}
}
// After all of the PDF "stuff" above is done and closed but **before** we
// close the MemoryStream, grab all of the active bytes from the stream
bytes = ms.ToArray();
}
// Clear the response
Response.Clear();
MemoryStream mstream = new MemoryStream(bytes);
// Define response content type
Response.ContentType = "application/pdf";
// Give the name of file of pdf and add in to header
Response.AddHeader("content-disposition", "attachment;filename=invoice.pdf");
Response.Buffer = true;
mstream.WriteTo(Response.OutputStream);
Response.End();
you can add gpx files to your project and use it:
edit scheme > options > allow location simulation > pick the file name that contains for example:
<?xml version="1.0"?>
<gpx version="1.1" creator="Xcode">
<wpt lat="41.92296" lon="-87.63892"></wpt>
</gpx>
optionally just hardcode the lat/lon values that are returned by the location manager. This is old style though.
so you won't add it to the simulator, but to your Xcode project.

Beginning PowerShell 5.0 New-Item
, Remove-Item
, and Get-ChildItem
have been enhanced to support creating and managing symbolic links. The ItemType parameter for New-Item
accepts a new value, SymbolicLink. Now you can create symbolic links in a single line by running the New-Item cmdlet.
New-Item -ItemType SymbolicLink -Path "C:\temp" -Name "calc.lnk" -Value "c:\windows\system32\calc.exe"
Be Carefull a SymbolicLink is different from a Shortcut, shortcuts are just a file. They have a size (A small one, that just references where they point) and they require an application to support that filetype in order to be used. A symbolic link is filesystem level, and everything sees it as the original file. An application needs no special support to use a symbolic link.
Anyway if you want to create a Run As Administrator shortcut using Powershell you can use
$file="c:\temp\calc.lnk"
$bytes = [System.IO.File]::ReadAllBytes($file)
$bytes[0x15] = $bytes[0x15] -bor 0x20 #set byte 21 (0x15) bit 6 (0x20) ON (Use –bor to set RunAsAdministrator option and –bxor to unset)
[System.IO.File]::WriteAllBytes($file, $bytes)
If anybody want to change something else in a .LNK file you can refer to official Microsoft documentation.

At your model add this:
public function scopeRandomize($query, $limit = 3, $exclude = [])
{
$query = $query->whereRaw('RAND()<(SELECT ((?/COUNT(*))*10) FROM `products`)', [$limit])->orderByRaw('RAND()')->limit($limit);
if (!empty($exclude)) {
$query = $query->whereNotIn('id', $exclude);
}
return $query;
}
then at route/controller
$data = YourModel::randomize(8)->get();
IMHO, it is more efficient to drop the table and re-create it. And yes, you can use "IF EXISTS" in this case.
I would use javascript for this.
var txtFile = new XMLHttpRequest();
txtFile.open("GET", "http://my.remote.url/myremotefile.txt", true);
txtFile.onreadystatechange = function() {
if (txtFile.readyState === 4 && txtFile.status == 200) {
allText = txtFile.responseText;
}
document.getElementById('your div id').innerHTML = allText;
This is just a code sample, would need tweaking for all browsers, etc.
This doesn't work for me. I've tried this both under Win7 64bit and Vista 32.
I'm using the below commandline to add this capability.
reg add "HKEY_CURRENT_USER\Software\Microsoft\Command Processor" /v AutoRun /t REG_SZ /d "IF x"%COMSPEC%"==x%CMDCMDLINE% (cd /D c:)"
You can use assertThrows()
, which allows you to test multiple exceptions within the same test. With support for lambdas in Java 8, this is the canonical way to test for exceptions in JUnit.
Per the JUnit docs:
import static org.junit.jupiter.api.Assertions.assertThrows;
@Test
void exceptionTesting() {
MyException thrown = assertThrows(
MyException.class,
() -> myObject.doThing(),
"Expected doThing() to throw, but it didn't"
);
assertTrue(thrown.getMessage().contains("Stuff"));
}

You need to set the password for root@localhost
to be blank. There are two ways:
The MySQL SET PASSWORD
command:
SET PASSWORD FOR root@localhost=PASSWORD('');
Using the command-line mysqladmin
tool:
mysqladmin -u root -pType_in_your_current_password_here password ''
The same error message results not only for null
but also for e.g. factor(0)
. In this case, the query must be if(length(element) > 0 & otherCondition)
or better check both cases with if(!is.null(element) & length(element) > 0 & otherCondition)
.
You want a check constraint.
CHECK constraints determine the valid values from a logical expression that is not based on data in another column. For example, the range of values for a salary column can be limited by creating a CHECK constraint that allows for only data that ranges from $15,000 through $100,000. This prevents salaries from being entered beyond the regular salary range.
You want something like:
ALTER TABLE dbo.Table ADD CONSTRAINT CK_Table_Frequency
CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
You can also implement check constraints with scalar functions, as described in the link above, which is how I prefer to do it.
I recently found tanerkuc's answer very helpful! Just wanted to add that using strrpos()
+ substr()
is slightly faster than explode()
+ end()
:
spl_autoload_register( function( $class ) {
$pos = strrpos( $class, '\\' );
include ( $pos === false ? $class : substr( $class, $pos + 1 ) ).'.php';
});
Try below command:

I don't believe there's any way to get a cell's color from a formula. The closest you can get is the CELL
formula, but (at least as of Excel 2003), it doesn't return the cell's color.
It would be pretty easy to implement with VBA:
Public Function myColor(r As Range) As Integer
myColor = r.Interior.ColorIndex
End Function
Then in the worksheet:
=mycolor(A1)
That you can do, but I think you should not break the normal flow of activity. If you want to finish you activity then you can simply send a broadcast from your activity B to activity A.
Create a broadcast receiver before starting your activity B:
BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent intent) {
String action = intent.getAction();
if (action.equals("finish_activity")) {
finish();
// DO WHATEVER YOU WANT.
}
}
};
registerReceiver(broadcastReceiver, new IntentFilter("finish_activity"));
Send broadcast from activity B to activity A when you want to finish activity A from B
Intent intent = new Intent("finish_activity");
sendBroadcast(intent);
I hope it will work for you...
ALTER TABLE TABLE_NAME MODIFY (COLUMN_NAME DROP IDENTITY);
Example with tables A and B:
A (parent) B (child)
============ =============
id | name pid | name
------------ -------------
1 | Alex 1 | Kate
2 | Bill 1 | Lia
3 | Cath 3 | Mary
4 | Dale NULL | Pan
5 | Evan
If you want to find parents and their kids, you do an INNER JOIN
:
SELECT id, parent.name AS parent
, pid, child.name AS child
FROM
parent INNER JOIN child
ON parent.id = child.pid
Result is that every match of a parent
's id
from the left table and a child
's pid
from the second table will show as a row in the result:
+----+--------+------+-------+
| id | parent | pid | child |
+----+--------+------+-------+
| 1 | Alex | 1 | Kate |
| 1 | Alex | 1 | Lia |
| 3 | Cath | 3 | Mary |
+----+--------+------+-------+
Now, the above does not show parents without kids (because their ids do not have a match in child's ids, so what do you do? You do an outer join instead. There are three types of outer joins, the left, the right and the full outer join. We need the left one as we want the "extra" rows from the left table (parent):
SELECT id, parent.name AS parent
, pid, child.name AS child
FROM
parent LEFT JOIN child
ON parent.id = child.pid
Result is that besides previous matches, all parents that do not have a match (read: do not have a kid) are shown too:
+----+--------+------+-------+
| id | parent | pid | child |
+----+--------+------+-------+
| 1 | Alex | 1 | Kate |
| 1 | Alex | 1 | Lia |
| 3 | Cath | 3 | Mary |
| 2 | Bill | NULL | NULL |
| 4 | Dale | NULL | NULL |
| 5 | Evan | NULL | NULL |
+----+--------+------+-------+
Where did all those NULL
come from? Well, MySQL (or any other RDBMS you may use) will not know what to put there as these parents have no match (kid), so there is no pid
nor child.name
to match with those parents. So, it puts this special non-value called NULL
.
My point is that these NULLs
are created (in the result set) during the LEFT OUTER JOIN
.
So, if we want to show only the parents that do NOT have a kid, we can add a WHERE child.pid IS NULL
to the LEFT JOIN
above. The WHERE
clause is evaluated (checked) after the JOIN
is done. So, it's clear from the above result that only the last three rows where the pid
is NULL will be shown:
SELECT id, parent.name AS parent
, pid, child.name AS child
FROM
parent LEFT JOIN child
ON parent.id = child.pid
WHERE child.pid IS NULL
Result:
+----+--------+------+-------+
| id | parent | pid | child |
+----+--------+------+-------+
| 2 | Bill | NULL | NULL |
| 4 | Dale | NULL | NULL |
| 5 | Evan | NULL | NULL |
+----+--------+------+-------+
Now, what happens if we move that IS NULL
check from the WHERE
to the joining ON
clause?
SELECT id, parent.name AS parent
, pid, child.name AS child
FROM
parent LEFT JOIN child
ON parent.id = child.pid
AND child.pid IS NULL
In this case the database tries to find rows from the two tables that match these conditions. That is, rows where parent.id = child.pid
AND child.pid IN NULL
. But it can find no such match because no child.pid
can be equal to something (1, 2, 3, 4 or 5) and be NULL at the same time!
So, the condition:
ON parent.id = child.pid
AND child.pid IS NULL
is equivalent to:
ON 1 = 0
which is always False
.
So, why does it return ALL rows from the left table? Because it's a LEFT JOIN! And left joins return rows that match (none in this case) and also rows from the left table that do not match the check (all in this case):
+----+--------+------+-------+
| id | parent | pid | child |
+----+--------+------+-------+
| 1 | Alex | NULL | NULL |
| 2 | Bill | NULL | NULL |
| 3 | Cath | NULL | NULL |
| 4 | Dale | NULL | NULL |
| 5 | Evan | NULL | NULL |
+----+--------+------+-------+
I hope the above explanation is clear.
Sidenote (not directly related to your question): Why on earth doesn't Pan
show up in none of our JOINs? Because his pid
is NULL
and NULL in the (not common) logic of SQL is not equal to anything so it can't match with any of the parent ids (which are 1,2,3,4 and 5). Even if there was a NULL there, it still wouldn't match because NULL
does not equal anything, not even NULL
itself (it's a very strange logic, indeed!). That's why we use the special check IS NULL
and not a = NULL
check.
So, will Pan
show up if we do a RIGHT JOIN
? Yes, it will! Because a RIGHT JOIN will show all results that match (the first INNER JOIN we did) plus all rows from the RIGHT table that don't match (which in our case is one, the (NULL, 'Pan')
row.
SELECT id, parent.name AS parent
, pid, child.name AS child
FROM
parent RIGHT JOIN child
ON parent.id = child.pid
Result:
+------+--------+------+-------+
| id | parent | pid | child |
+---------------+------+-------+
| 1 | Alex | 1 | Kate |
| 1 | Alex | 1 | Lia |
| 3 | Cath | 3 | Mary |
| NULL | NULL | NULL | Pan |
+------+--------+------+-------+
Unfortunately, MySQL does not have FULL JOIN
. You can try it in other RDBMSs, and it will show:
+------+--------+------+-------+
| id | parent | pid | child |
+------+--------+------+-------+
| 1 | Alex | 1 | Kate |
| 1 | Alex | 1 | Lia |
| 3 | Cath | 3 | Mary |
| 2 | Bill | NULL | NULL |
| 4 | Dale | NULL | NULL |
| 5 | Evan | NULL | NULL |
| NULL | NULL | NULL | Pan |
+------+--------+------+-------+
One workaround is to write .ToList().ForEach(x => ...)
.
pros
Easy to understand - reader only needs to know what ships with C#, not any additional extension methods.
Syntactic noise is very mild (only adds a little extranious code).
Doesn't usually cost extra memory, since a native .ForEach()
would have to realize the whole collection, anyway.
cons
Order of operations isn't ideal. I'd rather realize one element, then act on it, then repeat. This code realizes all elements first, then acts on them each in sequence.
If realizing the list throws an exception, you never get to act on a single element.
If the enumeration is infinite (like the natural numbers), you're out of luck.

Yours and VladLosevs' solutions are probably better than mine. If you want a brute-force solution, however, try this:
SET(CMAKE_EXE_LINKER_FLAGS /NODEFAULTLIB:\"msvcprtd.lib;MSVCRTD.lib\")
FOREACH(flag_var
CMAKE_CXX_FLAGS CMAKE_CXX_FLAGS_DEBUG CMAKE_CXX_FLAGS_RELEASE
CMAKE_CXX_FLAGS_MINSIZEREL CMAKE_CXX_FLAGS_RELWITHDEBINFO)
if(${flag_var} MATCHES "/MD")
string(REGEX REPLACE "/MD" "/MT" ${flag_var} "${${flag_var}}")
endif(${flag_var} MATCHES "/MD")
ENDFOREACH(flag_var)
To get largest size of the image
https://graph.facebook.com/{userID}?fields=picture.width(720).height(720)
or anything else you need as size. Based on experience, type=large is not the largest result you can obtain.
You should put it into command line in windows.
mysqladmin -u [username] -p flush-hosts
**** [MySQL password]
or
mysqladmin flush-hosts -u [username] -p
**** [MySQL password]
For network login use the following command:
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
you can permanently solution your problem by editing my.ini file[Mysql configuration file] change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";
=TEXT(A1,"0000")
However the TEXT function is able to do other fancy stuff like date formating, aswell.
Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:
"temp" environment variable setting - then it would be:
%temp%\Temporary ASP.NET Files
Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:
c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files
There are also cases where the temp folder can be set via config for a machine or site specific using this:
<compilation tempDirectory="d:\MyTempPlace" />
I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.
Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.
$date = strtotime("2017-12-11");
$newDate = date("Y-m-d", strtotime("+1 month", $date));
If you want to increment by days you can also do it
$date = strtotime("2017-12-11");
$newDate = date("Y-m-d", strtotime("+5 day", $date));
var calc = '<span style="display:none; margin:0 0 0 -999px">' + $('.move').text() + '</span>';
Please try this code:
sorted(glob.glob( os.path.join(path, '*.png') ),key=lambda x:float(re.findall("([0-9]+?)\.png",x)[0]))
It is, generally speaking, a bad idea to compare $(foo) with $(foo) as that is functionally equivalent to the following comparison:
<html>
<head>
<script language='javascript'>
function foo(bar) {
return ({ "object": bar });
}
$ = foo;
if ( $("a") == $("a") ) {
alert ("JS engine screw-up");
}
else {
alert ("Expected result");
}
</script>
</head>
</html>
Of course you would never expect "JS engine screw-up". I use "$" just to make it clear what jQuery is doing.
Whenever you call $("#foo") you are actually doing a jQuery("#foo") which returns a new object. So comparing them and expecting same object is not correct.
However what you CAN do may be is something like:
<html>
<head>
<script language='javascript'>
function foo(bar) {
return ({ "object": bar });
}
$ = foo;
if ( $("a").object == $("a").object ) {
alert ("Yep! Now it works");
}
else {
alert ("This should not happen");
}
</script>
</head>
</html>
So really you should perhaps compare the ID elements of the jQuery objects in your real program so something like
...
$(someIdSelector).attr("id") == $(someOtherIdSelector).attr("id")
is more appropriate.
If you don't care about supporting old browsers, you can use :not()
to exclude that element:
.parent:hover span:not(:hover) {
border: 10px solid red;
}
Demo: http://jsfiddle.net/vz9A9/1/
If you do want to support them, the I guess you'll have to either use JavaScript or override the CSS properties again:
.parent span:hover {
border: 10px solid green;
}
You can use the next code:
JS
function showname () {
var name = document.getElementById('fileInput');
alert('Selected file: ' + name.files.item(0).name);
alert('Selected file: ' + name.files.item(0).size);
alert('Selected file: ' + name.files.item(0).type);
};
HTML
<body>
<p>
<input type="file" id="fileInput" multiple onchange="showname()"/>
</p>
</body>
Why would you want to convert key strokes to text? Add a button that sends the text inside the textarea to the server when clicked. You can get the text using the value attribute as the poster before has pointed out, or using jQuery's API:
$('input#mybutton').click(function() {
var text = $('textarea#mytextarea').val();
//send to server and process response
});
I'm using version 4.4.2 and none of the other answers worked for me. But adding useMongoClient
to the options and putting it into a variable that you call close
on seemed to work.
var db = mongoose.connect('mongodb://localhost:27017/somedb', { useMongoClient: true })
//do stuff
db.close()
you will have to instantiate it before you throw it
throw new RuntimeException(arg0)
PS: Intrestingly enough the Netbeans IDE should have already pointed out that compile time error
It seems that OpenQA, guys behind Selenium, have already addressed this problem. They defined some variables to explicitely match whitespaces. In my case, I need to use an XPATH similar to //td[text()="${nbsp}"]
.
I reproduced here the text from OpenQA concerning this issue (found here):
HTML automatically normalizes whitespace within elements, ignoring leading/trailing spaces and converting extra spaces, tabs and newlines into a single space. When Selenium reads text out of the page, it attempts to duplicate this behavior, so you can ignore all the tabs and newlines in your HTML and do assertions based on how the text looks in the browser when rendered. We do this by replacing all non-visible whitespace (including the non-breaking space "
") with a single space. All visible newlines (<br>
,<p>
, and<pre>
formatted new lines) should be preserved.We use the same normalization logic on the text of HTML Selenese test case tables. This has a number of advantages. First, you don't need to look at the HTML source of the page to figure out what your assertions should be; "
" symbols are invisible to the end user, and so you shouldn't have to worry about them when writing Selenese tests. (You don't need to put "
" markers in your test case to assertText on a field that contains "
".) You may also put extra newlines and spaces in your Selenese<td>
tags; since we use the same normalization logic on the test case as we do on the text, we can ensure that assertions and the extracted text will match exactly.This creates a bit of a problem on those rare occasions when you really want/need to insert extra whitespace in your test case. For example, you may need to type text in a field like this: "
foo
". But if you simply write<td>foo </td>
in your Selenese test case, we'll replace your extra spaces with just one space.This problem has a simple workaround. We've defined a variable in Selenese,
${space}
, whose value is a single space. You can use${space}
to insert a space that won't be automatically trimmed, like this:<td>foo${space}${space}${space}</td>
. We've also included a variable${nbsp}
, that you can use to insert a non-breaking space.Note that XPaths do not normalize whitespace the way we do. If you need to write an XPath like
//div[text()="hello world"]
but the HTML of the link is really "hello world
", you'll need to insert a real "
" into your Selenese test case to get it to match, like this://div[text()="hello${nbsp}world"]
.
I know that this is an old topic but none of the solution mentioned worked for me. I have done something else that worked:
You need to:
Use c_str() to convert the std::string to const char *.
cout << "String is : " << text.c_str() << endl ;
in my case i just changed spring.postgresql.jdbc.url that contained IPV4, i changed it to 127.0.0.1
$_
last argument of last command$#
number of arguments passed to current script$*
/ $@
list of arguments passed to script as string / delimited listoff the top of my head. Google for bash special variables.
i think the safest way would be :
private int getActionBarHeight() {
int actionBarHeight = getSupportActionBar().getHeight();
if (actionBarHeight != 0)
return actionBarHeight;
final TypedValue tv = new TypedValue();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
} else if (getTheme().resolveAttribute(com.actionbarsherlock.R.attr.actionBarSize, tv, true))
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
return actionBarHeight;
}
Ctrl + Alt + L is format file (includes the two below)
Ctrl + Alt + O is optimize imports
Ctrl + Alt + I will fix indentation on a particular line
I usually run Ctrl + Alt + L a few times before committing my work. I'd rather it do the cleanup/reformatting at my command instead of automatically.
Basic thumb rule is: For "Nouns" use Abstract class and for "Verbs" use interface
E.g: car
is an abstract class and drive
, we can make it an interface.
You don't need jQuery for this. Here's a simple working example:
<!DOCTYPE html>
<html>
<head>
<title>box-shadow-experiment</title>
<style type="text/css">
#box-shadow-div{
position: fixed;
width: 1px;
height: 1px;
border-radius: 100%;
background-color:black;
box-shadow: 0 0 10px 10px black;
top: 49%;
left: 48.85%;
}
</style>
<script type="text/javascript">
window.onload = function(){
var bsDiv = document.getElementById("box-shadow-div");
var x, y;
// On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
window.addEventListener('mousemove', function(event){
x = event.clientX;
y = event.clientY;
if ( typeof x !== 'undefined' ){
bsDiv.style.left = x + "px";
bsDiv.style.top = y + "px";
}
}, false);
}
</script>
</head>
<body>
<div id="box-shadow-div"></div>
</body>
</html>
I chose position: fixed;
so scrolling wouldn't be an issue.
You probably need to update the remote URL since github puts your username in it. You can take a look at the original URL by typing
git config --get remote.origin.url
Or just go to the repository page on Github and get the new URL. Then use
git remote set-url origin https://{new url with username replaced}
to update the URL with your new username.
You could have a div for the top with one background and another for the main page, and seperate the page content between them or put the content in a floating div on another z-level. The way you are doing it may work but I doubt it will work across every browser you encounter.
If
(1) you have a _Layout.cshtml view like this
<html>
<body>
@RenderBody()
</body>
<script type="text/javascript" src="~/lib/layout.js"></script>
@RenderSection("scripts", required: false)
</html>
(2) you have Contacts.cshtml
@section Scripts{
<script type="text/javascript" src="~/lib/contacts.js"></script>
}
<div class="row">
<div class="col-md-6 col-md-offset-3">
<h2> Contacts</h2>
</div>
</div>
(3) you have About.cshtml
<div class="row">
<div class="col-md-6 col-md-offset-3">
<h2> Contacts</h2>
</div>
</div>
On you layout page, if required is set to false "@RenderSection("scripts", required: false)", When page renders and user is on about page, the contacts.js doesn't render.
<html>
<body><div>About<div>
</body>
<script type="text/javascript" src="~/lib/layout.js"></script>
</html>
if required is set to true "@RenderSection("scripts", required: true)", When page renders and user is on ABOUT page, the contacts.js STILL gets rendered.
<html>
<body><div>About<div>
</body>
<script type="text/javascript" src="~/lib/layout.js"></script>
<script type="text/javascript" src="~/lib/contacts.js"></script>
</html>
IN SHORT, when set to true, whether you need it or not on other pages, it will get rendered anyhow. If set to false, it will render only when the child page is rendered.
It's not possible. You need pull all repository or nothing.
Parse
throws an exception if it cannot parse the value, whereas TryParse
returns a bool
indicating whether it succeeded.
TryParse
does not just try
/catch
internally - the whole point of it is that it is implemented without exceptions so that it is fast. In fact the way it is most likely implemented is that internally the Parse
method will call TryParse
and then throw an exception if it returns false
.
In a nutshell, use Parse
if you are sure the value will be valid; otherwise use TryParse
.
okay, you can do this in one line of code. you'll need json2.js for this (you probably already have.). the two json objects here are unparsed strings.
json1 = '[{"foo":"bar"},{"bar":"foo"},{"name":"craig"}]';
json2 = '[{"foo":"baz"},{"bar":"fob"},{"name":"george"}]';
concattedjson = JSON.stringify(JSON.parse(json1).concat(JSON.parse(json2)));
target
isn't valid on an input
element.
In this case, though, your redirection is done by Javascript, so you could have your script open up a new window.
Try PyPDF2.
There is a good tutorial here: https://automatetheboringstuff.com/chapter13/
I am facing same problem, I was fixed it by generating gradle project and then adding lib project to android studio
First, See build.gradle file is present in project root directory
if not then, Create gradle project,

Create a .reg file containing your proxy settings for your users. Create a batch file setting it to setting it to run the .reg file with the extension /s
On a server using a logon script, tell the logon to run the batch file. Jason
I achived that wrote (located in the directory where my script is)
::someguy@host::$sudo -u user psql -d my_database -a -f file.sql
where -u user
is the role who owns the database where I want to execute the script then the psql
connects to the psql
console after that -d my_database
loads me in mydatabase
finally -a -f file.sql
where -a
echo all input from the script and -f
execute commands from file.sql
into mydatabase
, then exit.
I'm using: psql (PostgreSQL) 10.12 on (Ubuntu 10.12-0ubuntu0.18.04.1)
I think this should do it.
let today = new Date();
let form_date=new Date('2019-10-23')
let difference=form_date>today ? form_date-today : today-form_date
let diff_days=Math.floor(difference/(1000*3600*24))
If you have a problems with fusermount
command you can kill the process :
ps -ax | grep "sshfs"
First import Corelocation and MapKit library:
import MapKit
import CoreLocation
inherit from CLLocationManagerDelegate to our class
class ViewController: UIViewController, CLLocationManagerDelegate
create a locationManager variable, this will be your location data
var locationManager = CLLocationManager()
create a function to get the location info, be specific this exact syntax works:
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
in your function create a constant for users current location
let userLocation:CLLocation = locations[0] as CLLocation // note that locations is same as the one in the function declaration
stop updating location, this prevents your device from constantly changing the Window to center your location while moving (you can omit this if you want it to function otherwise)
manager.stopUpdatingLocation()
get users coordinate from userLocatin you just defined:
let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)
define how zoomed you want your map be:
let span = MKCoordinateSpanMake(0.2,0.2)
combine this two to get region:
let region = MKCoordinateRegion(center: coordinations, span: span)//this basically tells your map where to look and where from what distance
now set the region and choose if you want it to go there with animation or not
mapView.setRegion(region, animated: true)
close your function
}
from your button or another way you want to set the locationManagerDeleget to self
now allow the location to be shown
designate accuracy
locationManager.desiredAccuracy = kCLLocationAccuracyBest
authorize:
locationManager.requestWhenInUseAuthorization()
to be able to authorize location service you need to add this two lines to your plist
get location:
locationManager.startUpdatingLocation()
show it to the user:
mapView.showsUserLocation = true
This is my complete code:
import UIKit
import MapKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
@IBOutlet weak var mapView: MKMapView!
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func locateMe(sender: UIBarButtonItem) {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
mapView.showsUserLocation = true
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation:CLLocation = locations[0] as CLLocation
manager.stopUpdatingLocation()
let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)
let span = MKCoordinateSpanMake(0.2,0.2)
let region = MKCoordinateRegion(center: coordinations, span: span)
mapView.setRegion(region, animated: true)
}
}
In the future the format might need to be changed which could be a small head ache having date.dateFromISO8601 calls everywhere in an app. Use a class and protocol to wrap the implementation, changing the date time format call in one place will be simpler. Use RFC3339 if possible, its a more complete representation. DateFormatProtocol and DateFormat is great for dependency injection.
class AppDelegate: UIResponder, UIApplicationDelegate {
internal static let rfc3339DateFormat = "yyyy-MM-dd'T'HH:mm:ssZZZZZ"
internal static let localeEnUsPosix = "en_US_POSIX"
}
import Foundation
protocol DateFormatProtocol {
func format(date: NSDate) -> String
func parse(date: String) -> NSDate?
}
import Foundation
class DateFormat: DateFormatProtocol {
func format(date: NSDate) -> String {
return date.rfc3339
}
func parse(date: String) -> NSDate? {
return date.rfc3339
}
}
extension NSDate {
struct Formatter {
static let rfc3339: NSDateFormatter = {
let formatter = NSDateFormatter()
formatter.calendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierISO8601)
formatter.locale = NSLocale(localeIdentifier: AppDelegate.localeEnUsPosix)
formatter.timeZone = NSTimeZone(forSecondsFromGMT: 0)
formatter.dateFormat = rfc3339DateFormat
return formatter
}()
}
var rfc3339: String { return Formatter.rfc3339.stringFromDate(self) }
}
extension String {
var rfc3339: NSDate? {
return NSDate.Formatter.rfc3339.dateFromString(self)
}
}
class DependencyService: DependencyServiceProtocol {
private var dateFormat: DateFormatProtocol?
func setDateFormat(dateFormat: DateFormatProtocol) {
self.dateFormat = dateFormat
}
func getDateFormat() -> DateFormatProtocol {
if let dateFormatObject = dateFormat {
return dateFormatObject
} else {
let dateFormatObject = DateFormat()
dateFormat = dateFormatObject
return dateFormatObject
}
}
}
We show up two functions that prints a SINGLE character to binary.
void printbinchar(char character)
{
char output[9];
itoa(character, output, 2);
printf("%s\n", output);
}
printbinchar(10) will write into the console
1010
itoa is a library function that converts a single integer value to a string with the specified base. For example... itoa(1341, output, 10) will write in output string "1341". And of course itoa(9, output, 2) will write in the output string "1001".
The next function will print into the standard output the full binary representation of a character, that is, it will print all 8 bits, also if the higher bits are zero.
void printbincharpad(char c)
{
for (int i = 7; i >= 0; --i)
{
putchar( (c & (1 << i)) ? '1' : '0' );
}
putchar('\n');
}
printbincharpad(10) will write into the console
00001010
Now i present a function that prints out an entire string (without last null character).
void printstringasbinary(char* s)
{
// A small 9 characters buffer we use to perform the conversion
char output[9];
// Until the first character pointed by s is not a null character
// that indicates end of string...
while (*s)
{
// Convert the first character of the string to binary using itoa.
// Characters in c are just 8 bit integers, at least, in noawdays computers.
itoa(*s, output, 2);
// print out our string and let's write a new line.
puts(output);
// we advance our string by one character,
// If our original string was "ABC" now we are pointing at "BC".
++s;
}
}
Consider however that itoa don't adds padding zeroes, so printstringasbinary("AB1") will print something like:
1000001
1000010
110001
This is the code for the character you posted in your question: 
But that's not a checkbox character...
Solution when dropping a list of column names containing regex. I prefer this approach because I'm frequently editing the drop list. Uses a negative filter regex for the drop list.
drop_column_names = ['A','B.+','C.*']
drop_columns_regex = '^(?!(?:'+'|'.join(drop_column_names)+')$)'
print('Dropping columns:',', '.join([c for c in df.columns if re.search(drop_columns_regex,c)]))
df = df.filter(regex=drop_columns_regex,axis=1)
You can also misuse File.list(FilenameFilter) (and variants) for file traversal. Short code and works in early java versions, e.g:
// list files in dir
new File(dir).list(new FilenameFilter() {
public boolean accept(File dir, String name) {
String file = dir.getAbsolutePath() + File.separator + name;
System.out.println(file);
return false;
}
});
note that the span & group are indexed for multi capture groups in a regex
regex_with_3_groups=r"([a-z])([0-9]+)([A-Z])"
for match in re.finditer(regex_with_3_groups, string):
for idx in range(0, 4):
print(match.span(idx), match.group(idx))
Press Ctrl + T on the method name (rather than F3). This gives the type hierarchy as a pop-up so is slightly faster than using F4 and the type hierarchy view.
Also, when done on a method, subtypes that don't implement/override the method will be greyed out, and when you double click on a class in the list it will take you straight to the method in that class.
No need to convert. You can apply conditions on Enums inside a switch. Like so,
public enum Operator
{
PLUS,
MINUS,
MULTIPLY,
DIVIDE
}
public double Calculate(int left, int right, Operator op)
{
switch (op)
{
case Operator.PLUS: return left + right;
case Operator.MINUS: return left - right;
case Operator.MULTIPLY: return left * right;
case Operator.DIVIDE: return left / right;
default: return 0.0;
}
}
Then, call it like this:
Console.WriteLine("The sum of 5 and 5 is " + Calculate(5, 5, Operator.PLUS));
For Vanilla JavaScript there is simple and elegant way to do this:
for(var o of document.querySelectorAll('#DropList > option')) {
o.remove()
}
This can be achieved using column-count css property on parent div,
like
column-count:2;
check this out for more details.
You're effectively scanning the list once to find the min value, then scanning it again to find the index, you can do both in one go:
from operator import itemgetter
min(enumerate(a), key=itemgetter(1))[0]
You can use DOMNodeInserted
mutation event (no need delegation):
$('body').on('DOMNodeInserted', function(e) {
var target = e.target; //inserted element;
});
EDIT: Mutation events are deprecated, use mutation observer instead
- (void)changeColorWithString:(UILabel *)uilabel stringToReplace:(NSString *) stringToReplace uiColor:(UIColor *) uiColor{
NSMutableAttributedString *text =
[[NSMutableAttributedString alloc]
initWithAttributedString: uilabel.attributedText];
[text addAttribute: NSForegroundColorAttributeName value:uiColor range:[uilabel.text rangeOfString:stringToReplace]];
[uilabel setAttributedText: text];
}
For future Googlers, If you get an error similar below after you trigger click for a polygon
"Uncaught TypeError: Cannot read property 'vertex' of undefined"
then try the code below
google.maps.event.trigger(polygon, "click", {});
I have now come up with an own solution to this:
1. Created a general function to extract specific attributes from arrays
The function below extract only specific attributes from an associative array, or an array of associative arrays (the last is what you get when doing $collection->toArray() in Laravel).
It can be used like this:
$data = array_extract( $collection->toArray(), ['id','url'] );
I am using the following functions:
function array_is_assoc( $array )
{
return is_array( $array ) && array_diff_key( $array, array_keys(array_keys($array)) );
}
function array_extract( $array, $attributes )
{
$data = [];
if ( array_is_assoc( $array ) )
{
foreach ( $attributes as $attribute )
{
$data[ $attribute ] = $array[ $attribute ];
}
}
else
{
foreach ( $array as $key => $values )
{
$data[ $key ] = [];
foreach ( $attributes as $attribute )
{
$data[ $key ][ $attribute ] = $values[ $attribute ];
}
}
}
return $data;
}
This solution does not focus on performance implications on looping through the collections in large datasets.
2. Implement the above via a custom collection i Laravel
Since I would like to be able to simply do $collection->extract('id','url');
on any collection object, I have implemented a custom collection class.
First I created a general Model, which extends the Eloquent model, but uses a different collection class. All you models need to extend this custom model, and not the Eloquent Model then.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model as EloquentModel;
use Lib\Collection;
class Model extends EloquentModel
{
public function newCollection(array $models = [])
{
return new Collection( $models );
}
}
?>
Secondly I created the following custom collection class:
<?php
namespace Lib;
use Illuminate\Support\Collection as EloquentCollection;
class Collection extends EloquentCollection
{
public function extract()
{
$attributes = func_get_args();
return array_extract( $this->toArray(), $attributes );
}
}
?>
Lastly, all models should then extend your custom model instead, like such:
<?php
namespace App\Models;
class Article extends Model
{
...
Now the functions from no. 1 above are neatly used by the collection to make the $collection->extract()
method available.
Determine if string is a date, even if string is a non-standard format
(strtotime doesn't accept any custom format)
<?php
function validateDateTime($dateStr, $format)
{
date_default_timezone_set('UTC');
$date = DateTime::createFromFormat($format, $dateStr);
return $date && ($date->format($format) === $dateStr);
}
// These return true
validateDateTime('2001-03-10 17:16:18', 'Y-m-d H:i:s');
validateDateTime('2001-03-10', 'Y-m-d');
validateDateTime('2001', 'Y');
validateDateTime('Mon', 'D');
validateDateTime('March 10, 2001, 5:16 pm', 'F j, Y, g:i a');
validateDateTime('March 10, 2001, 5:16 pm', 'F j, Y, g:i a');
validateDateTime('03.10.01', 'm.d.y');
validateDateTime('10, 3, 2001', 'j, n, Y');
validateDateTime('20010310', 'Ymd');
validateDateTime('05-16-18, 10-03-01', 'h-i-s, j-m-y');
validateDateTime('Monday 8th of August 2005 03:12:46 PM', 'l jS \of F Y h:i:s A');
validateDateTime('Wed, 25 Sep 2013 15:28:57', 'D, d M Y H:i:s');
validateDateTime('17:03:18 is the time', 'H:m:s \i\s \t\h\e \t\i\m\e');
validateDateTime('17:16:18', 'H:i:s');
// These return false
validateDateTime('2001-03-10 17:16:18', 'Y-m-D H:i:s');
validateDateTime('2001', 'm');
validateDateTime('Mon', 'D-m-y');
validateDateTime('Mon', 'D-m-y');
validateDateTime('2001-13-04', 'Y-m-d');
I haven't tried it from a WebRequest, but both the Windows Media Player ActiveX and the MediaElement (from WPF) components are capable of playing and buffering MP3 streams.
I use it to play data coming from a SHOUTcast stream and it worked great. However, I'm not sure if it will work in the scenario you propose.
You could first build a list of keys to delete, and then iterate over that list deleting them.
dict = {'one' : 1, 'two' : 2, 'three' : 3, 'four' : 4}
delete = []
for k,v in dict.items():
if v%2 == 1:
delete.append(k)
for i in delete:
del dict[i]
You started with a one-dimensional list of numbers. Once you used numpy.newaxis
, you turned it into a two-dimensional matrix, consisting of four rows of one column each.
You could then use that matrix for matrix multiplication, or involve it in the construction of a larger 4 x n matrix.
If you want to do the same thing in C# based on Ciarán Answer
string sSheetName = null;
string sConnection = null;
DataTable dtTablesList = default(DataTable);
OleDbCommand oleExcelCommand = default(OleDbCommand);
OleDbDataReader oleExcelReader = default(OleDbDataReader);
OleDbConnection oleExcelConnection = default(OleDbConnection);
sConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Test.xls;Extended Properties=\"Excel 12.0;HDR=No;IMEX=1\"";
oleExcelConnection = new OleDbConnection(sConnection);
oleExcelConnection.Open();
dtTablesList = oleExcelConnection.GetSchema("Tables");
if (dtTablesList.Rows.Count > 0)
{
sSheetName = dtTablesList.Rows[0]["TABLE_NAME"].ToString();
}
dtTablesList.Clear();
dtTablesList.Dispose();
if (!string.IsNullOrEmpty(sSheetName)) {
oleExcelCommand = oleExcelConnection.CreateCommand();
oleExcelCommand.CommandText = "Select * From [" + sSheetName + "]";
oleExcelCommand.CommandType = CommandType.Text;
oleExcelReader = oleExcelCommand.ExecuteReader();
nOutputRow = 0;
while (oleExcelReader.Read())
{
}
oleExcelReader.Close();
}
oleExcelConnection.Close();
here is another way read Excel into a DataTable without using OLEDB very quick Keep in mind that the file ext would have to be .CSV for this to work properly
private static DataTable GetDataTabletFromCSVFile(string csv_file_path)
{
csvData = new DataTable(defaultTableName);
try
{
using (TextFieldParser csvReader = new TextFieldParser(csv_file_path))
{
csvReader.SetDelimiters(new string[]
{
tableDelim
});
csvReader.HasFieldsEnclosedInQuotes = true;
string[] colFields = csvReader.ReadFields();
foreach (string column in colFields)
{
DataColumn datecolumn = new DataColumn(column);
datecolumn.AllowDBNull = true;
csvData.Columns.Add(datecolumn);
}
while (!csvReader.EndOfData)
{
string[] fieldData = csvReader.ReadFields();
//Making empty value as null
for (int i = 0; i < fieldData.Length; i++)
{
if (fieldData[i] == string.Empty)
{
fieldData[i] = string.Empty; //fieldData[i] = null
}
//Skip rows that have any csv header information or blank rows in them
if (fieldData[0].Contains("Disclaimer") || string.IsNullOrEmpty(fieldData[0]))
{
continue;
}
}
csvData.Rows.Add(fieldData);
}
}
}
catch (Exception ex)
{
}
return csvData;
}
Why would we want to check if an array is empty
? Arrays don't grow or shrink in the same that lists do. Starting with a 'empty' array, and growing with np.append
is a frequent novice error.
Using a list in if alist:
hinges on its boolean value:
In [102]: bool([])
Out[102]: False
In [103]: bool([1])
Out[103]: True
But trying to do the same with an array produces (in version 1.18):
In [104]: bool(np.array([]))
/usr/local/bin/ipython3:1: DeprecationWarning: The truth value
of an empty array is ambiguous. Returning False, but in
future this will result in an error. Use `array.size > 0` to
check that an array is not empty.
#!/usr/bin/python3
Out[104]: False
In [105]: bool(np.array([1]))
Out[105]: True
and bool(np.array([1,2])
produces the infamous ambiguity error.
The accepted answer suggests size
:
In [11]: x = np.array([])
In [12]: x.size
Out[12]: 0
But I (and most others) check the shape
more than the size
:
In [13]: x.shape
Out[13]: (0,)
Another thing in its favor is that it 'maps' on to an empty
list:
In [14]: x.tolist()
Out[14]: []
But there are other other arrays with 0 size
, that aren't 'empty' in that last sense:
In [15]: x = np.array([[]])
In [16]: x.size
Out[16]: 0
In [17]: x.shape
Out[17]: (1, 0)
In [18]: x.tolist()
Out[18]: [[]]
In [19]: bool(x.tolist())
Out[19]: True
np.array([[],[]])
is also size 0, but shape (2,0) and len
2.
While the concept of an empty
list is well defined, an empty array
is not well defined. One empty list is equal to another. The same can't be said for a size 0
array.
The answer really depends on
I think the keystore file you want to use has a different or unsupported format in respect to your Java version. Could you post some more info of your task?
In general, to solve this issue you might need to recreate the whole keystore (using some other JDK version for example). In export-import the keys between the old and the new one - if you manage to open the old one somewhere else.
If it is simply an unsupported version, try the BouncyCastle crypto provider for example (although I'm not sure If it adds support to Java for more keystore types?).
Edit: I looked at the feature spec of BC.
A rather separable way of doing this is to use
import tensorflow as tf
from keras import backend as K
num_cores = 4

inter_op_parallelism_threads=num_cores,

K.set_session(session)
Here, with booleans
GPU
and CPU
, we indicate whether we would like to run our code with the GPU or CPU by rigidly defining the number of GPUs and CPUs the Tensorflow session is allowed to access. The variables num_GPU
and num_CPU
define this value. num_cores
then sets the number of CPU cores available for usage via intra_op_parallelism_threads
and inter_op_parallelism_threads
.
The intra_op_parallelism_threads
variable dictates the number of threads a parallel operation in a single node in the computation graph is allowed to use (intra). While the inter_ops_parallelism_threads
variable defines the number of threads accessible for parallel operations across the nodes of the computation graph (inter).
allow_soft_placement
allows for operations to be run on the CPU if any of the following criterion are met:
there is no GPU implementation for the operation
there are no GPU devices known or registered
there is a need to co-locate with other inputs from the CPU
All of this is executed in the constructor of my class before any other operations, and is completely separable from any model or other code I use.
Note: This requires tensorflow-gpu
and cuda
/cudnn
to be installed because the option is given to use a GPU.

The warning from your compiler is telling you that your format specifier doesn't match the data type you're passing to it.
Try using %lx
or %llx
. For more portability, include inttypes.h
and use the PRIx64
macro.
For example: printf("val = 0x%" PRIx64 "\n", val);
(note that it's string concatenation)
You should use Asset Catalog:
I have investigated, how we can use Asset Catalog; Now it seems to be easy for me. I want to show you steps to add icons and splash in asset catalog.
Note: No need to make any entry in info.plist file :) And no any other configuration.
In below image, at right side, you will see highlighted area, where you can mention which icons you need. In case of mine, i have selected first four checkboxes; As its for my app requirements. You can select choices according to your requirements.
Now, see below image. As you will select any App icon then you will see its detail at right side selected area. It will help you to upload correct resolution icon.
If Correct resolution image will not be added then following warning will come. Just upload the image with correct resolution.
After uploading all required dimensions, you shouldn't get any warning.
This should do it:
public function removeQueryParam(string $url, string $param): string
{
$parsedUrl = parse_url($url);
if (isset($parsedUrl[$param])) {
$baseUrl = strtok($url, '?');
parse_str(parse_url($url)['query'], $query);
unset($query[$param]);
return sprintf('%s?%s',
$baseUrl,
http_build_query($query)
);
}
return $url;
}
For a RollingLogFileAppender you also need these elements and values:
<rollingStyle value="Date" />
<staticLogFileName value="false" />
I ended up with a combination of Roberts and chirags answers:
((EditText)findViewById(R.id.search_field)).setOnEditorActionListener(
new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// Identifier of the action. This will be either the identifier you supplied,
// or EditorInfo.IME_NULL if being called due to the enter key being pressed.
if (actionId == EditorInfo.IME_ACTION_SEARCH
|| actionId == EditorInfo.IME_ACTION_DONE
|| event.getAction() == KeyEvent.ACTION_DOWN
&& event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
onSearchAction(v);
return true;
}
// Return true if you have consumed the action, else false.
return false;
}
});
Update: The above code would some times activate the callback twice. Instead I've opted for the following code, which I got from the Google chat clients:
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// If triggered by an enter key, this is the event; otherwise, this is null.
if (event != null) {
// if shift key is down, then we want to insert the '\n' char in the TextView;
// otherwise, the default action is to send the message.
if (!event.isShiftPressed()) {
if (isPreparedForSending()) {
confirmSendMessageIfNeeded();
}
return true;
}
return false;
}
if (isPreparedForSending()) {
confirmSendMessageIfNeeded();
}
return true;
}

First off, RangeToHTML
. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.
On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.
For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

The earliest versions of Unix time had a 32-bit integer incrementing at a rate of 60 Hz, which was the rate of the system clock on the hardware of the early Unix systems. The value 60 Hz still appears in some software interfaces as a result. The epoch also differed from the current value. The first edition Unix Programmer's Manual dated November 3, 1971 defines the Unix time as "the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second".
Something like this:
public static String innerSubString(String txt, char prefix, char suffix) {
if(txt != null && txt.length() > 1) {
int start = 0, end = 0;
char token;
for(int i = 0; i < txt.length(); i++) {
token = txt.charAt(i);
if(token == prefix)
start = i;
else if(token == suffix)
end = i;
}
if(start + 1 < end)
return txt.substring(start+1, end);
}
return null;
}
Use nnz instead of sum. No need for the double call to collapse matrices to vectors and it is likely faster than sum.
nnz(your_matrix == 5)
Here is how we got out of the infinite routing loop and still used $state.go
instead of $location.path
if('401' !== toState.name) {
if (principal.isIdentityResolved()) authorization.authorize();
}
If you still look for a solution, here's one that combined other answers (Bart Kiers and culmat) for your reference:

The asynchronous solution from Edward:
is simple and might just work for you.
I would also like to give a more advanced version which has these advantages:
This might be in particular useful in large software projects where you have many task executed repetitively in your process and you care about resource usage (threads) and also startup overhead.
Idea: Have one service thread which processes all registered timed tasks. Use boost io_service for that.
Code similar to: http://www.boost.org/doc/libs/1_65_1/doc/html/boost_asio/tutorial/tuttimer2/src.html
#include <cstdio>
#include <boost/asio.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
int main()
{
boost::asio::io_service io;
boost::asio::deadline_timer t(io, boost::posix_time::seconds(1));
t.async_wait([](const boost::system::error_code& /*e*/){
printf("Printed after 1s\n"); });
boost::asio::deadline_timer t2(io, boost::posix_time::seconds(1));
t2.async_wait([](const boost::system::error_code& /*e*/){
printf("Printed after 1s\n"); });
// both prints happen at the same time,
// but only a single thread is used to handle both timed tasks
// - namely the main thread calling io.run();
io.run();
return 0;
}
t
indicates for text mode
https://docs.python.org/release/3.1.5/library/functions.html#open
on linux, there's no difference between text mode and binary mode,
however, in windows, they converts \n
to \r\n
when text mode.
Here's a simple method:
public static boolean checkDatePattern(String padrao, String data) {
try {
SimpleDateFormat format = new SimpleDateFormat(padrao, LocaleUtils.DEFAULT_LOCALE);
format.parse(data);
return true;
} catch (ParseException e) {
return false;
}
}
The following configs works on Cent OS 6 or earlier
As stated above first have to disable selinux.
Step 1 nano /etc/sysconfig/selinux
Make sure the file has this configurations
SELINUX=disabled
SELINUXTYPE=targeted
Then restart the system
Step 2
iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT
Step 3
sudo service iptables save
For Cent OS 7
step 1
firewall-cmd --zone=public --permanent --add-port=8080/tcp
Step 2
firewall-cmd --reload
This way you can execute an action when all images inside body or any other container (that depends of your selection) are loaded. PURE JQUERY, no pluggins needed.
var counter = 0;
var size = $('img').length;
$("img").load(function() { // many or just one image(w) inside body or any other container
counter += 1;
counter === size && $('body').css('background-color', '#fffaaa'); // any action
}).each(function() {
this.complete && $(this).load();
});
$result = mysql_query($query) or die("Data not found.");
$rows=array();
while($r=mysql_fetch_assoc($result))
{
$rows[]=$r;
}
header("Content-type:application/json");
echo json_encode($rows);
I just don't see the functional and seamless reason for nulls not to be comparable to other values or other nulls, cause we can clearly compare it and say they are the same or not in our context. It's funny. Just because of some logical conclusions and consistency we need to bother constantly with it. It's not functional, make it more functional and leave it to philosophers and scientists to conclude if it's consistent or not and does it hold "universal logic". :) Someone may say that it's because of indexes or something else, I doubt that those things couldn't be made to support nulls same as values. It's same as comparing two empty glasses, one is vine glass and other is beer glass, we are not comparing the types of objects but values they contain, same as you could compare int and varchar, with null it's even easier, it's nothing and what two nothingness have in common, they are the same, clearly comparable by me and by everyone else that write sql, because we are constantly breaking that logic by comparing them in weird ways because of some ANSI standards. Why not use computer power to do it for us and I doubt it would slow things down if everything related is constructed with that in mind. "It's not null it's nothing", it's not apple it's apfel, come on... Functionally is your friend and there is also logic here. In the end only thing that matter is functionality and does using nulls in that way brings more or less functionality and ease of use. Is it more useful?
Consider this code:
SELECT CASE WHEN NOT (1 = null or (1 is null and null is null)) THEN 1 ELSE 0 end
How many of you knows what will this code return? With or without NOT it returns 0. To me that is not functional and it's confusing. In c# it's all as it should be, comparison operations return value, logically this too produces value, because if it didn't there is nothing to compare (except. nothing :) ). They just "said": anything compared to null "returns" 0 and that creates many workarounds and headaches.
This is the code that brought me here:
where a != b OR (a is null and b IS not null) OR (a IS not null and b IS null)
I just need to compare if two fields (in where) have different values, I could use function, but...
It's there because all controls in ASP .NET inherit from System.Web.UI.Control which has the "runat" attribute.
in the class System.Web.UI.HTMLControl, the attribute is not required, however, in the class System.Web.UI.WebControl the attribute is required.
edit: let me be more specific. since asp.net is pretty much an abstract of HTML, the compiler needs some sort of directive so that it knows that specific tag needs to run server-side. if that attribute wasn't there then is wouldn't know to process it on the server first. if it isn't there it assumes it is regular markup and passes it to the client.

Good luck.
The DroidUX component library has a ColorButton
widget whose color can be changed easily, both via xml definition and programmatically at run time, so you can even let the user to set the button's color/theme if your app allows it.
I'd suggest doing something similar to:
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = parent.getElementsByClassName('sub');
if (sub[0].style.display == 'inline'){
sub[0].style.display = 'none';
}
else {
sub[0].style.display = 'inline';
}
}
}
document.getElementById('cat').onclick = function(){
show_sub(this.id);
};????
Though the above relies on the use of a class
rather than a name
attribute equal to sub
.
As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:
Uncaught TypeError: Object # has no method 'getElementsByName'.
One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName()
, albeit crudely:
function eBCN(elem,classN){
if (!elem || !classN){
return false;
}
else {
var children = elem.childNodes;
for (var i=0,len=children.length;i<len;i++){
if (children[i].nodeType == 1
&&
children[i].className == classN){
var sub = children[i];
}
}
return sub;
}
}
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = eBCN(parent,'sub');
if (sub.style.display == 'inline'){
sub.style.display = 'none';
}
else {
sub.style.display = 'inline';
}
}
}
var D = document,
listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
listElems[i].onclick = function(){
show_sub(this.id);
};
}?
I was trying to compare A-B columns and highlight equal text, but usinng the obove fomrulas some text did not match at all. So I used form (VBA macro to compare two columns and color highlight cell differences) codes and I modified few things to adapt it to my application and find any desired column (just by clicking it). In my case, I use large and different numbers of rows on each column. Hope this helps:

Dim ColumnUsage As String

Set Report = Excel.ActiveSheet
vMatch = 1
'Select A and B Columns to compare
On Error Resume Next
Set A = Application.InputBox(Prompt:="Select column to compare", Title:="Column A", Type:=8)
If A Is Nothing Then Exit Sub
colA = Split(A(1).Address(1, 0), "$")(0)
Set B = Application.InputBox(Prompt:="Select column being searched", Title:="Column B", Type:=8)

colB = Split(B(1).Address(1, 0), "$")(0)

vMatch = vMatch + 1
Report.Cells(i, A.Column).Interior.ColorIndex = 35 'Light green background

It should be:
function moveItem() {
jQuery(".stripTransmitter ul li a").trigger('click');
}
setInterval(moveItem,2000);
setInterval(f, t)
calls the the argument function, f
, once every t
milliseconds.
The default generator for Windows seems to be set to NMAKE. Try to use:
cmake -G "MinGW Makefiles"
Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.
The problem is that you used the select option, this is where you went wrong. Select signifies that a textbox or textArea has a focus. What you need to do is use change. "Fires when a new choice is made in a select element", also used like blur when moving away from a textbox or textArea.
function start(){
document.getElementById("activitySelector").addEventListener("change", addActivityItem, false);
}
function addActivityItem(){
//option is selected
alert("yeah");
}
window.addEventListener("load", start, false);
My solution for changing seconds (number) to string format (for example: 'mm:ss'):
const formattedSeconds = moment().startOf('day').seconds(S).format('mm:ss');
Write your seconds instead 'S' in example. And just use the 'formattedSeconds' where you need.
It seems that no one has mentioned the switch --stat

You did not say "in the browser". Otherwise, you can use Node.js modules. These are the same for each require
call. Basic example:
The contents of foo.js:
const circle = require('./circle.js'); console.log(`The area of a circle of radius 4 is ${circle.area(4)}`);
The contents of circle.js:
const PI = Math.PI; exports.area = (r) => PI * r * r; exports.circumference = (r) => 2 * PI * r;
Note that you cannot access circle.PI
, as it is not exported.
While this does not work in the browser, it is simple and clean.
Do not store the embed code in your database -- YouTube may change the embed code and URL parameters from time to time. For example the <object>
embed code has been retired in favor of <iframe>
embed code. You should parse out the video id from the URL/embed code (using regular expressions, URL parsing functions or HTML parser) and store it. Then display it using whatever mechanism currently offered by YouTube API.
A naive PHP example for extracting the video id is as follows:
<?php
preg_match(
'/[\\?\\&]v=([^\\?\\&]+)/',
'http://www.youtube.com/watch?v=OzHvVoUGTOM&feature=channel',
$matches
);
// $matches[1] should contain the youtube id
?>
I suggest that you look at these articles to figure out what to do with these ids:
To create your own YouTube video player:
In Windows Server LDAP is a protocol which is used for access Active Directory object, user authentication, authorization.
$("#elementName option").text();
This will give selected text of Combo-Box.
$("#elementName option").val();
This will give selected value associated selected item in Combo-Box.
$("#elementName option").length;
It will give the multi-select combobox values in the array and length will give number of element of the array.
Note:#elementName is id the Combo-box.
For a more generic and extensible way check mergedict. It uses singledispatch
and can merge values based on its types.
Example:
from mergedict import MergeDict
class SumDict(MergeDict):
@MergeDict.dispatch(int)
def merge_int(this, other):
return this + other
d2 = SumDict({'a': 1, 'b': 'one'})
d2.merge({'a':2, 'b': 'two'})
assert d2 == {'a': 3, 'b': 'two'}
Also the following command works:
describe SELECT * FROM table_name;
Where the select statement can be replaced with any other select statement, which is quite useful for complex inserts with select for example.
The "Issue 2" answer given by @Sagar works for the majority of git servers such as gitorious.
However, there will be a name clash in a system like gitolite where the public ssh keys are checked in as files named with the username, ie keydir/jenkins.pub
. What if there are multiple jenkins servers that need to access the same gitolite server?
(Note: this is about running the Jenkins daemon not running a build job as a user (addressed by @Sagar's "Issue 1").)
So in this case you do need to run the Jenkins daemon as a different user.
There are two steps:
The main thing is to update the JENKINS_USER
environment variable. Here's a patch showing how to change the user to ptran
.

You need to use gdb's memory-display commands. The basic one is x
, for examine. There's an example on the linked-to page that uses
gdb> x/4xw $sp
to print "four words (w
) of memory above the stack pointer (here, $sp
) in hexadecimal (x
)". The quotation is slightly paraphrased.
Try the Date
function. It will give you today's date in a MM/DD/YYYY format. If you're looking for today's date in the MM-DD-YYYY format try Date$
. Now()
also includes the current time (which you might not need). It all depends on what you need. :)

VirtualBox version has many uncompatibilities with Linux version, so it's hard to install by using "Guest Addition CD image". For linux distributions it's frequently have a good companion Guest Addition package(equivalent functions to the CD image) which can be installed by:
sudo apt-get install virtualbox-guest-dkms
After that, on the window menu of the Guest, go to Devices->Shared Folders Settings->Shared Folders and add a host window folder to Machine Folders(Mark Auto-mount option) then you can see the shared folder in the Files of Guest Linux.
The data would probably have been posted originally from a web form looking a bit like this (but probably much more complicated):
<form action="http://example.com" method="post">
User login <input name="user[login]" /><br />
User password <input name="user[password]" /><br />
<input type="submit" />
</form>
If the method were "get" instead of "post", clicking the submit button would take you to a URL looking a bit like this:
http://example.com/?user%5Blogin%5D=username&user%5Bpassword%5D=123456
or:
http://example.com/?user[login]=username&user[password]=123456
The web server on the other end will likely take the user[login]
and user[password]
parameters, and make them into a user
object with login
and password
fields containing those values.
You can try like below:
app.directive("directive_name", function(){
return {
restrict:'E',
transclude:true,
template:'<div class="title"><h2>{{title}}</h3></div>',
scope:{
accept:"="
},
replace:true
};
})
it sets up a two-way binding between the value of the 'accept' attribute and the parent scope.
And also you can set two way data binding with property: '='
For example, if you want both key and value bound to the local scope you would do:
scope:{
key:'=',
value:'='
},

So, if you want to pass an argument from controller to directive, then refer this below fiddle

I know that this is an old question but I wanted to write my answer for visual learners. I couldn't find any diagrams explaining output buffering on the worldwide-web so I made a diagram myself in Windows mspaint.exe
.
If output buffering is turned off, then echo
will send data immediately to the Browser.
If output buffering is turned on, then an echo
will send data to the output buffer before sending it to the Browser.
phpinfo
To see whether Output buffering is turned on / off please refer to phpinfo at the core section. The output_buffering
directive will tell you if Output buffering is on/off.
In this case the output_buffering
value is 4096 which means that the buffer size is 4 KB. It also means that Output buffering is turned on, on the Web server.
php.ini
It's possible to turn on/off and change buffer size by changing the value of the output_buffering
directive. Just find it in php.ini
, change it to the setting of your choice, and restart the Web server. You can find a sample of my php.ini
below.
; Output buffering is a mechanism for controlling how much output data
; (excluding headers and cookies) PHP should keep internally before pushing that
; data to the client. If your application's output exceeds this setting, PHP
; will send that data in chunks of roughly the size you specify.
; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance
; reasons.
; Note: Output buffering can also be controlled via Output Buffering Control
; functions.
; Possible Values:
; On = Enabled and buffer is unlimited. (Use with caution)
; Off = Disabled
; Integer = Enables the buffer and sets its maximum size in bytes.
; Note: This directive is hardcoded to Off for the CLI SAPI
; Default Value: Off
; Development Value: 4096
; Production Value: 4096
; http://php.net/output-buffering
output_buffering = 4096
The directive output_buffering
is not the only configurable directive regarding Output buffering. You can find other configurable Output buffering directives here: http://php.net/manual/en/outcontrol.configuration.php
Example: ob_get_clean()
Below you can see how to capture an echo
and manipulate it before sending it to the browser.
// Turn on output buffering
ob_start();
echo 'Hello World'; // save to output buffer
$output = ob_get_clean(); // Get content from the output buffer, and discard the output buffer ...
$output = strtoupper($output); // manipulate the output
echo $output; // send to output stream / Browser
// OUTPUT:
HELLO WORLD

That will work just fine. You can export an entire calendar with File
> Export…
, or individual events by dragging them to the Finder.
iCalendar (.ics
) files are human-readable, so you can always pop it open in a text editor to make sure no private events made it in there. They consist of nested sections with start with BEGIN:
and end with END:
. You'll mostly find VEVENT
sections (each of which represents an event) and VTIMEZONE
sections, each of which represents a time zone that's referenced from one or more events.
Following event handler should do the needful:
$('[name=mobilePhone]').on('keyup', function(e){
var enteredNumberStr=this.$('[name=mobilePhone]').val(),
//Filter only numbers from the input
cleanedStr = (enteredNumberStr).replace(/\D/g, ''),
inputLength=cleanedStr.length,
formattedNumber=cleanedStr;
if(inputLength>3 && inputLength<7) {
formattedNumber= cleanedStr.substr(0,3) + '-' + cleanedStr.substr(3,inputLength-1) ;
}else if (inputLength>=7 && inputLength<10) {
formattedNumber= cleanedStr.substr(0,3) + '-' + cleanedStr.substr(3,3) + '-' + cleanedStr.substr(6,inputLength-1);
}else if(inputLength>=10) {
formattedNumber= cleanedStr.substr(0,3) + '-' + cleanedStr.substr(3,3) + '-' + cleanedStr.substr(6,inputLength-1);
}
console.log(formattedNumber);
this.$('[name=mobilePhone]').val(formattedNumber);
});
Angular filters can only be applied to arrays and not objects, from angular's API -
"Selects a subset of items from array and returns it as a new array."
You have two options here:
1) move $scope.items
to an array or -
2) pre-filter the ng-repeat
items, like this:
<div ng-repeat="(k,v) in filterSecId(items)">
{{k}} {{v.pos}}
</div>
And on the Controller:
$scope.filterSecId = function(items) {
var result = {};
angular.forEach(items, function(value, key) {
if (!value.hasOwnProperty('secId')) {
result[key] = value;
}
});
return result;
}
jsfiddle: http://jsfiddle.net/bmleite/WA2BE/
Actually you can fix it with following steps -
cls.__dict__
{'isFilled':True}
or {'isFilled':False}
depending upon what you have set.del cls.__dict__['isFilled']
In this case, we delete the entry which overrides the method as mentioned by BrenBarn.
For .js
files that expose more than one variable (unlike drawGauge
), a better solution would be to set the Typescript compiler to process .js
files.
In your tsconfig.json
, set allowJs
option to true:
"compilerOptions": {
...
"allowJs": true,
...
}
Otherwise, you'll have to declare each and every variable in either your component.ts
or d.ts
.
If the lack of source code bothers you, I have another alternative.
@echo off
for /f "delims=" %%p in ('ReadLine -h -p "Enter password: "') do set PWD=%%p
echo You entered: %PWD%
You can get it from https://westmesatech.com/?page_id=49. Source code is included.
I came across this post while searching for a way to clear the entire form related to the BFCache (back/forward button cache) in Chrome.
In addition to what Sim supplied, my use case required that the details needed to be combined with Clear Form on Back Button?.
I found that the best way to do this is in allow the form to behave as it expects, and to trigger an event:
$(window).bind("pageshow", function() {
var form = $('form');
// let the browser natively reset defaults
form[0].reset();
});
If you are not handling the input
events to generate an object in JavaScript, or something else for that matter, then you are done. However, if you are listening to the events, then at least in Chrome you need to trigger a change
event yourself (or whatever event you care to handle, including a custom one):
form.find(':input').not(':button,:submit,:reset,:hidden').trigger('change');
That must be added after the reset
to do any good.
Real's Java How-to posts this solution, which is also compatible for versions before Java 1.6.
BigDecimal bd = new BigDecimal(Double.toString(d));
bd = bd.setScale(decimalPlace, BigDecimal.ROUND_HALF_UP);
return bd.doubleValue();
BigDecimal bd = new BigDecimal(Double.toString(number));
bd = bd.setScale(decimalPlaces, RoundingMode.HALF_UP);
return bd.doubleValue();
JSON.stringify(data).length return string length not Object length, you can use Object.keys.
<% for(var i=0; i < Object.keys(data).length ; i++) {%>
On linux you can check epiphany-browser, resizes the windows you'll get same bugs as in ios. Both browsers uses Webkit.

Seaching for answer I couldn't find any to be easy and flexible at the same time, then I found the Spring Security Reference and I realized there are near to perfect solutions. AOP solutions often are the greatest ones for testing, and Spring provides it with @WithMockUser
, @WithUserDetails
and @WithSecurityContext
, in this artifact:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-test</artifactId>
<version>4.2.2.RELEASE</version>
<scope>test</scope>
</dependency>
In most cases, @WithUserDetails
gathers the flexibility and power I need.
Basically you just need to create a custom UserDetailsService
with all the possible users profiles you want to test. E.g
@TestConfiguration
public class SpringSecurityWebAuxTestConfig {
@Bean
@Primary
public UserDetailsService userDetailsService() {
User basicUser = new UserImpl("Basic User", "[email protected]", "password");
UserActive basicActiveUser = new UserActive(basicUser, Arrays.asList(
new SimpleGrantedAuthority("ROLE_USER"),
new SimpleGrantedAuthority("PERM_FOO_READ")
));
User managerUser = new UserImpl("Manager User", "[email protected]", "password");
UserActive managerActiveUser = new UserActive(managerUser, Arrays.asList(
new SimpleGrantedAuthority("ROLE_MANAGER"),
new SimpleGrantedAuthority("PERM_FOO_READ"),
new SimpleGrantedAuthority("PERM_FOO_WRITE"),
new SimpleGrantedAuthority("PERM_FOO_MANAGE")
));
return new InMemoryUserDetailsManager(Arrays.asList(
basicActiveUser, managerActiveUser
));
}
}
Now we have our users ready, so imagine we want to test the access control to this controller function:
@RestController
@RequestMapping("/foo")
public class FooController {
@Secured("ROLE_MANAGER")
@GetMapping("/salute")
public String saluteYourManager(@AuthenticationPrincipal User activeUser)
{
return String.format("Hi %s. Foo salutes you!", activeUser.getUsername());
}
}
Here we have a get mapped function to the route /foo/salute and we are testing a role based security with the @Secured
annotation, although you can test @PreAuthorize
and @PostAuthorize
as well.
Let's create two tests, one to check if a valid user can see this salute response and the other to check if it's actually forbidden.
@RunWith(SpringRunner.class)
@SpringBootTest(
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
classes = SpringSecurityWebAuxTestConfig.class
)
@AutoConfigureMockMvc
public class WebApplicationSecurityTest {
@Autowired
private MockMvc mockMvc;
@Test
@WithUserDetails("[email protected]")
public void givenManagerUser_whenGetFooSalute_thenOk() throws Exception
{
mockMvc.perform(MockMvcRequestBuilders.get("/foo/salute")
.accept(MediaType.ALL))
.andExpect(status().isOk())
.andExpect(content().string(containsString("[email protected]")));
}
@Test
@WithUserDetails("[email protected]")
public void givenBasicUser_whenGetFooSalute_thenForbidden() throws Exception
{
mockMvc.perform(MockMvcRequestBuilders.get("/foo/salute")
.accept(MediaType.ALL))
.andExpect(status().isForbidden());
}
}
As you see we imported SpringSecurityWebAuxTestConfig
to provide our users for testing. Each one used on its corresponding test case just by using a straightforward annotation, reducing code and complexity.
As you see @WithUserDetails
has all the flexibility you need for most of your applications. It allows you to use custom users with any GrantedAuthority, like roles or permissions. But if you are just working with roles, testing can be even easier and you could avoid constructing a custom UserDetailsService
. In such cases, specify a simple combination of user, password and roles with @WithMockUser.
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
@WithSecurityContext(
factory = WithMockUserSecurityContextFactory.class
)
public @interface WithMockUser {
String value() default "user";
String username() default "";
String[] roles() default {"USER"};
String password() default "password";
}
The annotation defines default values for a very basic user. As in our case the route we are testing just requires that the authenticated user be a manager, we can quit using SpringSecurityWebAuxTestConfig
and do this.
@Test
@WithMockUser(roles = "MANAGER")
public void givenManagerUser_whenGetFooSalute_thenOk() throws Exception
{
mockMvc.perform(MockMvcRequestBuilders.get("/foo/salute")
.accept(MediaType.ALL))
.andExpect(status().isOk())
.andExpect(content().string(containsString("user")));
}
Notice that now instead of the user [email protected] we are getting the default provided by @WithMockUser
: user; yet it won't matter because what we really care about is his role: ROLE_MANAGER
.
As you see with annotations like @WithUserDetails
and @WithMockUser
we can switch between different authenticated users scenarios without building classes alienated from our architecture just for making simple tests. Its also recommended you to see how @WithSecurityContext works for even more flexibility.

I'm a novice, but this is my self taught way of doing it:
ifstream input_file("example.txt", ios::in | ios::binary)
streambuf* buf_ptr = input_file.rdbuf(); //pointer to the stream buffer
input.get(); //extract one char from the stream, to activate the buffer
input.unget(); //put the character back to undo the get()
size_t file_size = buf_ptr->in_avail();
//a value of 0 will be returned if the stream was not activated, per line 3.
The short answer is that SQL Server (as of SQL 2008) does not support cross database foreign keys--as the error message states.
While you cannot have declarative referential integrity (the FK), you can reach the same goal using triggers. It's a bit less reliable, because the logic you write may have bugs, but it will get you there just the same.
See the SQL docs @ http://msdn.microsoft.com/en-us/library/aa258254%28v=sql.80%29.aspx Which state:
Triggers are often used for enforcing business rules and data integrity. SQL Server provides declarative referential integrity (DRI) through the table creation statements (ALTER TABLE and CREATE TABLE); however, DRI does not provide cross-database referential integrity. To enforce referential integrity (rules about the relationships between the primary and foreign keys of tables), use primary and foreign key constraints (the PRIMARY KEY and FOREIGN KEY keywords of ALTER TABLE and CREATE TABLE). If constraints exist on the trigger table, they are checked after the INSTEAD OF trigger execution and prior to the AFTER trigger execution. If the constraints are violated, the INSTEAD OF trigger actions are rolled back and the AFTER trigger is not executed (fired).
There is also an OK discussion over at SQLTeam - http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=31135
The best way is to use justifyContent property
<View style={{flexDirection:'column',justifyContent:'flex-end'}}>
<View>
<Text>fixed footer</Text>
</View>
</View>
if you have multiple view elements on screen, then you can use
<View style={{flexDirection:'column',justifyContent:'space-between'}}>
<View>
<Text>view 1</Text>

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans
POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.
There are two problems in your code:
visibility
and not visiblity
..style
property.It's easy to fix. Simple replace this:
document.getElementById("remember").visiblity
with this:
document.getElementById("remember").style.visibility
If your YAML file looks like this:
# tree format
treeroot:
branch1:
name: Node 1
branch1-1:
name: Node 1-1
branch2:
name: Node 2
branch2-1:
name: Node 2-1
And you've installed PyYAML
like this:
pip install PyYAML
And the Python code looks like this:
import yaml
with open('tree.yaml') as f:
# use safe_load instead load
dataMap = yaml.safe_load(f)
The variable dataMap
now contains a dictionary with the tree data. If you print dataMap
using PrettyPrint, you will get something like:
{
'treeroot': {
'branch1': {
'branch1-1': {
'name': 'Node 1-1'
},
'name': 'Node 1'
},
'branch2': {
'branch2-1': {
'name': 'Node 2-1'
},
'name': 'Node 2'
}
}
}
So, now we have seen how to get data into our Python program. Saving data is just as easy:
with open('newtree.yaml', "w") as f:
yaml.dump(dataMap, f)
You have a dictionary, and now you have to convert it to a Python object:
class Struct:
def __init__(self, **entries):
self.__dict__.update(entries)
Then you can use:
>>> args = your YAML dictionary
>>> s = Struct(**args)
>>> s
<__main__.Struct instance at 0x01D6A738>
>>> s...
and follow "Convert Python dict to object".
For more information you can look at pyyaml.org and this.
If you want to pass a JavaScript object/hash (ie. an associative array in PHP) then you would do:
$.post('/url/to/page', {'key1': 'value', 'key2': 'value'});
If you wanna pass an actual array (ie. an indexed array in PHP) then you can do:
$.post('/url/to/page', {'someKeyName': ['value','value']});
If you want to pass a JavaScript array then you can do:
$.post('/url/to/page', {'someKeyName': variableName});
You can use ::after

I needed real multithreading in Node.js and what worked for me was the threads package. It spawns another process having it's own Node.js message loop, so they don't block each other. The setup is easy and the documentation get's you up and running fast. Your main program and the workers can communicate in both ways and worker "threads" can be killed if needed.
Since multithreading and Node.js is a complicated and widely discussed topic it was quite difficult to find a package that works for my specific requirement. For the record these did not work for me:
require
-ing modules in workers which I neededAnd for those asking why I needed real multi-threading: For an application involving the Raspberry Pi and interrupts. One thread is handling those interrupts and another takes care of storing the data (and more).

I know this is a very old thread but I was looking for a solution to the same problem and I came across this before eventually finding the answer and I wanted to just post it here so somebody else in my shoes would have a shorter trek across the internet.
****Note that you probably have to run cmd.exe as an administrator for this to work**
So here we go, open up the prompt (as an adminstrator) and go to your System32 directory. Then run
C:\Windows\System32>cd ras
Now you'll be in the ras directory. Now it's time to create a temporary file with our connection info that we will then append onto the rasphone.pbk file that will allow us to use the rasdial command.
So to create our temp file run:
C:\Windows\System32\ras>copy con temp.txt
Now it will let you type the contents of the file, which should look like this:
[CONNECTION NAME]
MEDIA=rastapi
Port=VPN2-0
Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=vpn.server.address.com
So replace CONNECTION NAME and vpn.server.address.com with the desired connection name and the vpn server address you want.
Make a new line and press Ctrl+Z to finish and save.
Now we will append this onto the rasphone.pbk file that may or may not exist depending on if you already have network connections configured or not. To do this we will run the following command:
C:\Windows\System32\ras>type temp.txt >> rasphone.pbk
This will append the contents of temp.txt to the end of rasphone.pbk, or if rasphone.pbk doesn't exist it will be created. Now we might as well delete our temp file:
C:\Windows\System32\ras>del temp.txt
Now we can connect to our newly configured VPN server with the following command:
C:\Windows\System32\ras>rasdial "CONNECTION NAME" myUsername myPassword
When we want to disconnect we can run:
C:\Windows\System32\ras>rasdial /DISCONNECT
That should cover it! I've included a direct copy and past from the command line of me setting up a connection for and connecting to a canadian vpn server with this method:

You can use this:
function sanitize(string) {
const map = {
'&': '&',
'<': '<',
'>': '>',
'"': '"',
"'": ''',
"/": '/',
};
const reg = /[&<>"'/]/ig;
return string.replace(reg, (match)=>(map[match]));
}

In theory the 4 digit option is right. But in practice it might be better to have 1900-2099 range.
Additionally it need to be non-capturing group. Many comments and answers propose capturing grouping which is not proper IMHO. Because for matching it might work, but for extracting matches using regex it will extract 4 digit numbers and two digit (19 and 20) numbers also because of paranthesis.
This will work for exact matching using non-capturing groups:
(?:19|20)\d{2}

How about calling a function from within your callback instead of returning a value in sync_call()?
function sync_call(input) {
var value;
// Assume the async call always succeed
async_call(input, function(result) {
value = result;
use_value(value);
} );
}
Before using v-html
, you have to make sure that the element which you escape is sanitized in case you allow user input, otherwise you expose your app to xss vulnerabilities.
More info here: https://vuejs.org/v2/guide/security.html
I highly encourage you that instead of using v-html
to use this npm package
It means you allow every (*
) user-agent/crawler to access the root (/
) of your site. You're okay.
I had a similar problem and was able to solve it by following the below approach (similar to other answers but needed credentials too),
1- add Microsoft.SharePointOnline.CSOM by tools->NuGet Package Manager->Manage NuGet Packages for solution->Browse-> select and install
2- Add "using Microsoft.SharePoint.Client; "
then the below code
string siteUrl = "https://yourcompany.sharepoint.com/sites/Yoursite";
SecureString passWord = new SecureString();
var password = "Your password here";
var securePassword = new SecureString();
foreach (char c in password)
{
securePassword.AppendChar(c);
}
ClientContext clientContext = new ClientContext(siteUrl);
clientContext.Credentials = new SharePointOnlineCredentials("[email protected]", securePassword);/*passWord*/
List oList = clientContext.Web.Lists.GetByTitle("The name of your list here");
ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();
ListItem oListItem = oList.AddItem(itemCreateInfo);
oListItem["PK"] = "1";
oListItem["Precinct"] = "Mangere";
oListItem["Title"] = "Innovation";
oListItem["Project_x005F_x0020_Name"] = "test from C#";
oListItem["Project_x005F_x0020_ID"] = "ID_123_from C#";
oListItem["Project_x005F_x0020_start_x005F_x0020_date"] = "2020-05-01 01:01:01";
oListItem.Update();
clientContext.ExecuteQuery();
Remember that your fields may be different with what you see, for example in my list I see "Project Name", while the actual value is "Project_x005F_x0020_ID". How to get these values (i.e. internal filed values)?
A few approaches:
1- Use MS flow and see them
2- https://mstechtalk.com/check-column-internal-name-sharepoint-list/ or https://sharepoint.stackexchange.com/questions/787/finding-the-internal-name-and-display-name-for-a-list-column
3- Use a C# reader and read your sharepoint list

There are three parts:
You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:
#!path/to/interpretter
To find the path to your python interpretter on your machine you can run the command:
which python
This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:
#!/usr/bin/python
You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:
chmod +x myscript.py
The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:
echo $PATH
This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:
which <commandname>
Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:
export PATH=/my/directory/with/pythonscript:$PATH
Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile
While I appreciate you believe absolute paths is not an option, it is a better option than relative paths and updating the PHP include path.
Use absolute paths with an constant you can set based on environment.
if (is_production()) {
define('ROOT_PATH', '/some/production/path');
}
else {
define('ROOT_PATH', '/root');
}
include ROOT_PATH . '/connect.php';
As commented, ROOT_PATH
could also be derived from the current path, $_SERVER['DOCUMENT_ROOT']
, etc.
The changelog is sloppily worded. from __future__ import absolute_import
does not care about whether something is part of the standard library, and import string
will not always give you the standard-library module with absolute imports on.
from __future__ import absolute_import
means that if you import string
, Python will always look for a top-level string
module, rather than current_package.string
. However, it does not affect the logic Python uses to decide what file is the string
module. When you do
python pkg/script.py
pkg/script.py
doesn't look like part of a package to Python. Following the normal procedures, the pkg
directory is added to the path, and all .py
files in the pkg
directory look like top-level modules. import string
finds pkg/string.py
not because it's doing a relative import, but because pkg/string.py
appears to be the top-level module string
. The fact that this isn't the standard-library string
module doesn't come up.
To run the file as part of the pkg
package, you could do
python -m pkg.script
In this case, the pkg
directory will not be added to the path. However, the current directory will be added to the path.
You can also add some boilerplate to pkg/script.py
to make Python treat it as part of the pkg
package even when run as a file:
if __name__ == '__main__' and __package__ is None:
__package__ = 'pkg'
However, this won't affect sys.path
. You'll need some additional handling to remove the pkg
directory from the path, and if pkg
's parent directory isn't on the path, you'll need to stick that on the path too.

Try this , if you are using PHP 5.3+, in php
$query_date = '2010-02-04';
$date = new DateTime($query_date);
//First day of month
$date->modify('first day of this month');
$firstday= $date->format('Y-m-d');
//Last day of month
$date->modify('last day of this month');
$lastday= $date->format('Y-m-d');
For finding next month last date, modify as follows,
$date->modify('last day of 1 month');
echo $date->format('Y-m-d');
and so on..
In some cases if you delete your Bin
and Obj
folders will solve this problem.
I think it is important to mention, now that this question is over 1 year old, that Socket.IO has since come out and seems to be the primary way to work with sockets in the browser now; it is also compatible with Node.js as far as I know.

I've hit this problem so many times, but actually, it's quite straightforward to track down the cause.
Here's today's example. I was calling my POST service with an AccountRequest
object, but when I put a breakpoint at the start of this function, the parameter value was always null
. But why ?!
[ProducesResponseType(typeof(DocumentInfo[]), 201)]
[HttpPost]
public async Task<IActionResult> Post([FromBody] AccountRequest accountRequest)
{
// At this point... accountRequest is null... but why ?!
// ... other code ...
}
To identify the problem, change the parameter type to string
, add a line to get JSON.Net
to deserialize the object into the type you were expecting, and put a breakpoint on this line:
[ProducesResponseType(typeof(DocumentInfo[]), 201)]
[HttpPost]
public async Task<IActionResult> Post([FromBody] string ar)
{
// Put a breakpoint on the following line... what is the value of "ar" ?
AccountRequest accountRequest = JsonConvert.DeserializeObject<AccountRequest>(ar);
// ... other code ...
}
Now, when you try this, if the parameter is still blank or null
, then you simply aren't calling the service properly.
However, if the string does contain a value, then the DeserializeObject
should point you towards the cause of the problem, and should also fail to convert your string into your desired format. But with the raw (string
) data which it's trying to deserialize, you should now be able to see what's wrong with your parameter value.
(In my case, we were calling the service with an AccountRequest
object which had been accidentally serialized twice !)
Fundamentally, Turing-completeness is one concise requirement, unbounded recursion.
Not even bounded by memory.
I thought of this independently, but here is some discussion of the assertion. My definition of LSP provides more context.
The other answers here don't directly define the fundamental essence of Turing-completeness.
If you don't want to include any special character, then try this much simple way for checking special characters using RegExp \W Metacharacter.
var iChars = "~`!#$%^&*+=-[]\\\';,/{}|\":<>?";
if(!(iChars.match(/\W/g)) == "") {
alert ("File name has special characters ~`!#$%^&*+=-[]\\\';,/{}|\":<>? \nThese are not allowed\n");
return false;
}
It should be noted GROUP BY
is not always necessary as (at least in PostgreSQL, and likely in other SQL variants) you can use ORDER BY
with a list and you can still use ASC
or DESC
per column...
SELECT name_first, name_last, dob
FROM those_guys
ORDER BY name_last ASC, name_first ASC, dob DESC;
I think this table is short and usefull:
Supplier () -> x
Consumer x -> ()
Callable () -> x throws ex
Runnable () -> ()
Function x -> y
BiFunction x,y -> z
Predicate x -> boolean
UnaryOperator x1 -> x2
BinaryOperator x1,x2 -> x3
As said on the other answers, the appropriate option for this problem is a Runnable
No, *
will match zero-or-more characters. You should use +
, which matches one-or-more instead.
This expression might work better for you: [A-Z]+123
inside the Android manifest file of your project, find the activity declaration of whose you want to fix the orientation and add the following piece of code ,
android:screenOrientation="landscape"
for landscape orientation and for portrait add the following code,
android:screenOrientation="portrait"
Why do you need to? Attributes give extra information for reflection, but if you externally know which properties you want you don't need them.
You could store meta data externally relatively easily in a database or resource file.
I had the same issue. I came up with a simple solution. Use fragment .replace
instead of fragment .add
. Replacing fragment doing the same thing as adding fragment and then removing it manually.
getFragmentManager().beginTransaction().replace(fragment).commit();
instead of
getFragmentManager().beginTransaction().add(fragment).commit();
While a lot of others should be mentioned, Apache Wicket should be preferred.
Wicket doesn't just reduce lots of boilerplate code, it actually removes it entirely and you can work with excellent separation of business code and markup without mixing the two and a wide variety of other things you can read about from the website.
@choz answer is the correct way. If you have many usages and want to make sure it works everywhere without changes you can add these small migration-snippet:
/* Migration jQuery from 1.8 to 3.x */
jQuery.fn.load = function (callback) {
var el = $(this);
el.on('load', callback);
return el;
};
In this case you got no erros on other nodes e.g. on $image
like in @Korsmakolnikov answer!
const $image = $('img.image').load(function() {
$(this).doSomething();
});
$image.doSomethingElseWithTheImage();
Make sure that you've installed these required packages.Worked perfectly in my case as i installed the checked packages
