You have at least these 3 issues:
display
yet in your javascript you attempt to get element myDiv
which is not even defined in your markup.You can save all three values at once by doing:
var title=new Array();
var names=new Array();//renamed to names -added an S-
//to avoid conflicts with the input named "name"
var tickets=new Array();
function insert(){
var titleValue = document.getElementById('title').value;
var actorValue = document.getElementById('name').value;
var ticketsValue = document.getElementById('tickets').value;
title[title.length]=titleValue;
names[names.length]=actorValue;
tickets[tickets.length]=ticketsValue;
}
And then change the show function to:
function show() {
var content="<b>All Elements of the Arrays :</b><br>";
for(var i = 0; i < title.length; i++) {
content +=title[i]+"<br>";
}
for(var i = 0; i < names.length; i++) {
content +=names[i]+"<br>";
}
for(var i = 0; i < tickets.length; i++) {
content +=tickets[i]+"<br>";
}
document.getElementById('display').innerHTML = content; //note that I changed
//to 'display' because that's
//what you have in your markup
}
Here's a jsfiddle for you to play around.
Import-Csv $path | Foreach-Object {
foreach ($property in $_.PSObject.Properties)
{
doSomething $property.Name, $property.Value
}
}
This is called the "shape" in NumPy, and can be requested via the .shape
attribute:
>>> a = zeros((2, 5))
>>> a.shape
(2, 5)
If you prefer a function, you could also use numpy.shape(a)
.
I would suspect that there can be as many as 2**32 -1
numbered match variables, on a 32-bit compiled Perl binary.
Using JavaScript
public ActionResult Index()
{
return Content("<script>window.location = 'http://www.example.com';</script>");
}
Note: As @Jeremy Ray Brown said , This is not the best option but you might find useful in some situations.
Hope this helps.
Try this Code
var app = angular.module('myapp', []);
app.controller('testController', function ($scope, $http) {
$scope.init = function(){
alert($scope.testInput);
};});
<body ng-app="myapp">_x000D_
<div ng-controller='testController' data-ng-init="testInput='value'; init();" class="col-sm-9 col-lg-9" >_x000D_
</div>_x000D_
</body>
_x000D_
SELECT LEFT(CONVERT(varchar, GetDate(),112),6)
$(".oSlider-rotate").slider({
min: 10,
max: 74,
step: .01,
value: 24,
slide: function(e,ui){
$('.user-text').css('transform', 'scale(' + ui.value + ')')
}
});
This will solve the issue
This worked for me like a charm:
row.DataGridView.Enabled = false;
row.DefaultCellStyle.BackColor = Color.LightGray;
row.DefaultCellStyle.ForeColor = Color.DarkGray;
(where row = DataGridView.NewRow(appropriate overloads);)
You are missing the @Id
entity property, and that's why Hibernate is throwing that exception.
Any JPA entity must have an identifier property, that is marked with the Id
annotation.
There are two types of identifiers:
An assigned identifier looks as follows:
@Id
private Long id;
Notice that we are using a wrapper (e.g.,
Long
,Integer
) instead of a primitive type (e.g.,long
,int
). Using a wrapper type is a better choice when using Hibernate because, by checking if theid
isnull
or not, Hibernate can better determine if an entity is transient (it does not have an associated table row) or detached (it has an associated table row, but it's not managed by the current Persistence Context).
The assigned identifier must be set manually by the application prior to calling persist:
Post post = new Post();
post.setId(1L);
entityManager.persist(post);
An auto-generated identifier requires the @GeneratedValue
annotation besides the @Id
:
@Id
@GeneratedValue
private int id;
There are 3 strategies Hibernate can use to auto-generate the entity identifier:
IDENTITY
SEQUENCE
TABLE
The IDENTITY
strategy is to be avoided if the underlying database supports sequences (e.g., Oracle, PostgreSQL, MariaDB since 10.3, SQL Server since 2012). The only major database that does not support sequences is MySQL.
The problem with
IDENTITY
is that automatic Hibernate batch inserts are disabled for this strategy.
The SEQUENCE
strategy is the best choice unless you are using MySQL. For the SEQUENCE
strategy, you also want to use the pooled
optimizer to reduce the number of database roundtrips when persisting multiple entities in the same Persistence Context.
The TABLE
generator is a terrible choice because it does not scale. For portability, you are better off using SEQUENCE
by default and switch to IDENTITY
for MySQL only.
I needed column names as a flat array, while the other answers returned associative arrays, so I used:
$con = mysqli_connect('localhost',$db_user,$db_pw,$db_name);
$table = 'people';
/**
* Get the column names for a mysql table
**/
function get_column_names($con, $table) {
$sql = 'DESCRIBE '.$table;
$result = mysqli_query($con, $sql);
$rows = array();
while($row = mysqli_fetch_assoc($result)) {
$rows[] = $row['Field'];
}
return $rows;
}
$col_names = function get_column_names($con, $table);
$col_names now equals:
(
[0] => name
[1] => parent
[2] => number
[3] => chart_id
[4] => type
[5] => id
)
If the form was successfully submitted, $_POST['userName']
should always be set, though it may contain an empty string, which is different from not being set at all. Instead check if it is empty()
if (isset($_POST['submit'])) {
if (empty($_POST['userName'])) {
$username = 'Anonymous';
} else {
$username = $_POST['userName'];
}
}
I've just installed 64 bit Node.js v0.12.0 for Windows 8.1 from here. It's about 8MB and since it's an MSI you just double click to launch. It will automatically set up your environment paths etc.
Then to get the command line it's just [Win-Key]+[S]
for search and then enter "node.js" as your search phrase.
Choose the Node.js Command Prompt
entry NOT the Node.js
entry.
Both will given you a command prompt but only the former will actually work. npm is built into that download so then just npm -whatever
at prompt.
Setting the top and left properties to negative values might not be a good workaround if your problem is simply that you're in quirks mode. This can happen if the page is missing a <!DOCTYPE>
declaration, causing it to be rendered in quirks mode in IE8. In IE8 Developer Tools, make sure that "Quirks Mode" is not selected under "Document Mode". If it is selected, you may need to add the appropriate <!DOCTYPE>
declaration.
First of all, tf.train.GradientDescentOptimizer
is designed to use a constant learning rate for all variables in all steps. TensorFlow also provides out-of-the-box adaptive optimizers including the tf.train.AdagradOptimizer
and the tf.train.AdamOptimizer
, and these can be used as drop-in replacements.
However, if you want to control the learning rate with otherwise-vanilla gradient descent, you can take advantage of the fact that the learning_rate
argument to the tf.train.GradientDescentOptimizer
constructor can be a Tensor
object. This allows you to compute a different value for the learning rate in each step, for example:
learning_rate = tf.placeholder(tf.float32, shape=[])
# ...
train_step = tf.train.GradientDescentOptimizer(
learning_rate=learning_rate).minimize(mse)
sess = tf.Session()
# Feed different values for learning rate to each training step.
sess.run(train_step, feed_dict={learning_rate: 0.1})
sess.run(train_step, feed_dict={learning_rate: 0.1})
sess.run(train_step, feed_dict={learning_rate: 0.01})
sess.run(train_step, feed_dict={learning_rate: 0.01})
Alternatively, you could create a scalar tf.Variable
that holds the learning rate, and assign it each time you want to change the learning rate.
Thanks for this post. I got this worked for using mustache templates in my asp.net mvc project I used the following, and it worked for me.
<system.webServer>
<staticContent>
<mimeMap fileExtension=".mustache" mimeType="text/html"/>
</staticContent>
</system.WebServer>
If performance doesn't matter, you could serialize them and compare the results:
var serializer = new XmlSerializer(typeof(TheObjectType));
StringWriter serialized1 = new StringWriter(), serialized2 = new StringWriter();
serializer.Serialize(serialized1, obj1);
serializer.Serialize(serialized2, obj2);
bool areEqual = serialized1.ToString() == serialized2.ToString();
And a code example:
<div ng-app>
<div ng-controller="FooController">
<ul ng-repeat="item in items | orderBy:'num':true">
<li>{{item.num}} :: {{item.desc}}</li>
</ul>
</div>
</div>
And the JavaScript:
function FooController($scope) {
$scope.items = [
{desc: 'a', num: 1},
{desc: 'b', num: 2},
{desc: 'c', num: 3},
];
}
Will give you:
3 :: c
2 :: b
1 :: a
On JSFiddle: http://jsfiddle.net/agjqN/
The results will completely depend on the browser, to give an objective verdict, we have to make some performance tests, here are some results, you can run them here:
Chrome 6:
Firefox 3.6:
Firefox 4.0b2:
Safari 5:

You have to do two things:
I'm guessing that your complaint is that the exception is not firing. PDO is most likely configured to not throw exceptions. Enable them with this:
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
I find it useful, because when I didn't know about env, before I started to write script I was doing this:
type nodejs > scriptname.js #or any other environment
and then I was modifying that line in the file into shebang.
I was doing this, because I didn't always remember where is nodejs on my computer -- /usr/bin/ or /bin/, so for me env
is very useful. Maybe there are details with this, but this is my reason
According to the GCC page for C++11:
To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well.
Did you compile with -std=gnu++0x
?
I'm guessing you have a NUL byte in input.csv. You can test that with
if '\0' in open('input.csv').read():
print "you have null bytes in your input file"
else:
print "you don't"
if you do,
reader = csv.reader(x.replace('\0', '') for x in mycsv)
may get you around that. Or it may indicate you have utf16 or something 'interesting' in the .csv file.
This question is not new and existing answers give some good theoretical background. I just want to add a more pragmatic answer.
getText is a method of the Context abstract class and in order to call it, one needs an instance of it's subclass (Activity, Service, Application or other). The problem is, that the public static final variables are initialized before any instance of Context is created.
There are several ways to solve this:
just because you don't have the right to acess the file , use
chmod -R 755 /var/log/nginx;
or you can change to sudo then it
I worked so much, I hope my effort might help you out.
Just paste this into your SSMS and press F5:

This query will give you 3 results:
1. Catch the error in case something goes wrong (don't panic, it will always show you an error above 4000 characters because NVARCHAR(MAX) can only store till 4000 characters)
2. Put the JSON into a string (which is what we want)
3. BONUS: parse the JSON and nicely store the data into a table (how cool is that?)

Turn off pre compiled headers:
Project Properties -> C++ -> Precompiled Headers
set Precompiled Header
to "Not Using Precompiled Header"
.
My way of achieving this is by creating ZipInputStream wrapping class that would handle that would provide only the stream of current entry:
The wrapper class:
public class ZippedFileInputStream extends InputStream {
private ZipInputStream is;
public ZippedFileInputStream(ZipInputStream is){
this.is = is;
}
@Override
public int read() throws IOException {
return is.read();
}
@Override
public void close() throws IOException {
is.closeEntry();
}
}
The use of it:
ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("SomeFile.zip"));
while((entry = zipInputStream.getNextEntry())!= null) {
ZippedFileInputStream archivedFileInputStream = new ZippedFileInputStream(zipInputStream);
//... perform whatever logic you want here with ZippedFileInputStream
// note that this will only close the current entry stream and not the ZipInputStream
archivedFileInputStream.close();
}
zipInputStream.close();
One advantage of this approach: InputStreams are passed as an arguments to methods that process them and those methods have a tendency to immediately close the input stream after they are done with it.
You asked how to escape an Apostrophe character (')
in SQL Server. All the answers above do an excellent job of explaining that.
However, depending on the situation, the Right single quotation mark character (’)
might be appropriate.
(No escape characters needed)
-- Direct insert
INSERT INTO Table1 (Column1) VALUES ('John’s')
• Apostrophe (U+0027)
• Right single quotation mark (U+2019)
Here's one slight alteration to the answers of a query that creates the table upon execution (i.e. you don't have to create the table first):
SELECT * INTO #Temp
FROM (
select OptionNo, OptionName from Options where OptionActive = 1
) as X
var inputs = document.querySelectorAll("input[type=text]") ||
(function() {
var ret=[], elems = document.getElementsByTagName('input'), i=0,l=elems.length;
for (;i<l;i++) {
if (elems[i].type.toLowerCase() === "text") {
ret.push(elems[i]);
}
}
return ret;
}());
You can enable NuGet packages and update you dlls. so that it work. or you can update the package manually by going through the package manager in your vs if u know which version you require for your solution.
Stan0 intial idea is not a good idea. There can be multiple files with the same name. Very error prone implementation. Stan0's second idea is the correct way.
When you first upload the file to google drive store its id (in SharedPreferences is probably easiest) for later use
ie.
file= mDrive.files().insert(body).execute(); //initial insert of file to google drive
whereverYouWantToStoreIt= file.getId(); //now you have the guaranteed unique id
//of the file just inserted. Store it and use it
//whenever you need to fetch this file
Why does it work in Chrome and not Firefox?
The W3 spec for CORS preflight requests clearly states that user credentials should be excluded. There is a bug in Chrome and WebKit where OPTIONS
requests returning a status of 401 still send the subsequent request.
Firefox has a related bug filed that ends with a link to the W3 public webapps mailing list asking for the CORS spec to be changed to allow authentication headers to be sent on the OPTIONS
request at the benefit of IIS users. Basically, they are waiting for those servers to be obsoleted.
How can I get the OPTIONS
request to send and respond consistently?
Simply have the server (API in this example) respond to OPTIONS
requests without requiring authentication.
Kinvey did a good job expanding on this while also linking to an issue of the Twitter API outlining the catch-22 problem of this exact scenario interestingly a couple weeks before any of the browser issues were filed.
I faced this error when I was trying to build Selenium source on Ubuntu. The simple shell script with correct shebang was not able to run even after I had all pre-requisites covered.
file file-name # helped me in understanding that CRLF ending were present in the file.
I opened the file in Vim and I could see that just because I once edited this file on a Windows machine, it was in DOS format. I converted the file to Unix format with below command:
dos2unix filename # actually helped me and things were fine.
I hope that we should take care whenever we edit files across platforms we should take care for the file formats as well.
String dt = Date.Now.ToString("yyyy-MM-dd");
Now you got this for dt, 2010-09-09
According to documentation: to verify host or peer certificate you need to specify alternate certificates with the CURLOPT_CAINFO
option or a certificate directory can be specified with the CURLOPT_CAPATH
option.
Also look at CURLOPT_SSL_VERIFYHOST:
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
In the case where you simply want to delete a project from the head revision, so that it no longer shows up in your repo when you run svn list file:///path/to/repo/
just run:
svn delete file:///path/to/repo/project
However, if you need to delete all record of it in the repo, use another method.
REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET
or POST
, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)
With REST, you might instead PUT /profiles/cHao
and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.
http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.
use Json & jQuery. It's way easier than oldschool javascript

var t3 = $row.find(':nth-child(3)').text();

My answer is based on this answer: How can I get the current contents of an element in webdriver just more like copy-paste.
from selenium import webdriver
driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')
element_text = element.text
element_attribute_value = element.get_attribute('value')
print (element)
print ('element.text: {0}'.format(element_text))
print ('element.get_attribute(\'value\'): {0}'.format(element_attribute_value))
element = driver.find_element_by_css_selector('.description.expand_description > p')
element_text = element.text
element_attribute_value = element.get_attribute('value')
print (element)
print ('element.text: {0}'.format(element_text))
print ('element.get_attribute(\'value\'): {0}'.format(element_attribute_value))
driver.quit()
If you don't want to have the current error handling behaviour, it's really easy:
return text.Split(',').Select(x => int.Parse(x));
Otherwise, I'd use an extra helper method (as seen this morning!):
public static int? TryParseInt32(string text)
{
int value;
return int.TryParse(text, out value) ? value : (int?) null;
}
and:
return text.Split(',').Select<string, int?>(TryParseInt32)
.Where(x => x.HasValue)
.Select(x => x.Value);
or if you don't want to use the method group conversion:
return text.Split(',').Select(t => t.TryParseInt32(t)
.Where(x => x.HasValue)
.Select(x => x.Value);
or in query expression form:
return from t in text.Split(',')
select TryParseInt32(t) into x
where x.HasValue
select x.Value;
From javascript, you should be able to get the filename in the onsubmit handler. So in your case, you should do something like:
<form onsubmit="if (document.getElementById('fileUpload').value.match(/xls$/) || document.getElementById('fileUpload').value.match(/xlsx$/)) { alert ('Bad file type') ; return false; } else { return true; }">...</form>
// Once finished with the bitmap objects, we deallocate them.
originalBMP.Dispose();
bannerBMP.Dispose();
oGraphics.Dispose();
This is a programming style that you'll regret sooner or later. Sooner is knocking on the door, you forgot one. You are not disposing newBitmap. Which keeps a lock on the file until the garbage collector runs. If it doesn't run then the second time you try to save to the same file you'll get the klaboom. GDI+ exceptions are too miserable to give a good diagnostic so serious head-scratching ensues. Beyond the thousands of googlable posts that mention this mistake.
Always favor using the using statement. Which never forgets to dispose an object, even if the code throws an exception.
using (var newBitmap = new Bitmap(thumbBMP)) {
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
}
Albeit that it is very unclear why you even create a new bitmap, saving thumbBMP should already be good enough. Anyhoo, give the rest of your disposable objects the same using love.
You may also use access
in combination with opendir
to determine if the directory exists, and, if the name exists, but is not a directory. For example:
/* test that dir exists (1 success, -1 does not exist, -2 not dir) */
int
xis_dir (const char *d)
{
DIR *dirptr;
if (access ( d, F_OK ) != -1 ) {
// file exists
if ((dirptr = opendir (d)) != NULL) {
closedir (dirptr); /* d exists and is a directory */
} else {
return -2; /* d exists but is not a directory */
}
} else {
return -1; /* d does not exist */
}
return 1;
}

split :: Eq a => a -> [a] -> [[a]]
split d [] = []
split d s = x : split d (drop 1 y) where (x,y) = span (/= d) s
E.g.
split ';' "a;bb;ccc;;d"

A single trailing delimiter will be dropped:
split ';' "a;bb;ccc;;d;"
> ["a","bb","ccc","","d"]
The problem with iframes not getting 100% height is not because they're unwieldy. The problem is that for them to get 100% height they need their parents to have 100% height. If one of the iframe's parents is not 100% tall the iframe won't be able to go beyond that parent's height.
So the best possible solution would be:
html, body, iframe { height: 100%; }
…given the iframe is directly under body. If the iframe has a parent between itself and the body, the iframe will still get the height of its parent. One must explicitly set the height of every parent to 100% as well (if that's what one wants).
Tested in:
Chrome 30
, Firefox 24
, Safari 6.0.5
, Opera 16
, IE 7, 8, 9 and 10
PS: I don't mean to be picky but the solution marked as correct doesn't work on Firefox 24
at the time of this writing, but worked on Chrome 30
. Haven't tested on other browsers though. I came across the error on Firefox
because the page I was testing had very little content... It could be it's my meager markup or the CSS
reset altering the output, but if I experienced this error I guess the accepted answer doesn't work in every situation.
Update 2021
@Zeni suggested this in 2015:
iframe { height: 100vh }
...and indeed it does the trick!
Careful with positioning as it can potentially break the effect. Test thoroughly, you might not need positioning depending of what you're trying to achieve.
it is the problem of misunderstand of cookie. Browsers recognize cookie values for not just keys also compare the options path & domain. So Browsers recognize different value which cookie values that key is 'name' with server setting option(path='/'; domain='mydomain.com') and key is 'name' with no option.
With the help of xpath locator also, you can achieve the same.
Your statement would be:
driver.findElement(By.xpath(".//a[contains(@href,'long')]")).click();
And for clicking all the links contains long in the URL, you can use:-
List<WebElement> linksList = driver.findElements(By.xpath(".//a[contains(@href,'long')]"));
for (WebElement webElement : linksList){
webElement.click();
}
https://socket.io/docs/#What-Socket-IO-is-not (with my emphasis)
What Socket.IO is not
Socket.IO is NOT a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the packet id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server either. Please see the protocol specification here.
// WARNING: the client will NOT be able to connect! const client = io('ws://echo.websocket.org');
There are two BeanUtils.copyProperties(parameter1, parameter2) in Java.
One is

Pay attention to the opposite position of parameters.
Just a quick modification to DaniP's answer, for anyone dealing with elements that can sometimes extend beyond the bounds of the device's viewport.
Added just a slight conditional - In the case of elements that are bigger than the viewport, the element will be revealed once it's top half has completely filled the viewport.
function elementInView(el) {
// The vertical distance between the top of the page and the top of the element.
var elementOffset = $(el).offset().top;
// The height of the element, including padding and borders.
var elementOuterHeight = $(el).outerHeight();
// Height of the window without margins, padding, borders.
var windowHeight = $(window).height();
// The vertical distance between the top of the page and the top of the viewport.
var scrollOffset = $(this).scrollTop();
if (elementOuterHeight < windowHeight) {
// Element is smaller than viewport.
if (scrollOffset > (elementOffset + elementOuterHeight - windowHeight)) {
// Element is completely inside viewport, reveal the element!
return true;
}
} else {
// Element is larger than the viewport, handle visibility differently.
// Consider it visible as soon as it's top half has filled the viewport.
if (scrollOffset > elementOffset) {
// The top of the viewport has touched the top of the element, reveal the element!
return true;
}
}
return false;
}

I had issues with twitter boot strap in IE. No rounded corners. Navigation menu not collapsing. Spans not sitting in correct location, even some images not displaying.
Strangely, site works okay in IE when run through visual studio debugger, its once deployed to a server that the problem occurs.
Try using IE developer tools (F12 is keyboard shortcut) Check your browser mode and document mode. (its at the top along side the menu bar)
Problem happened for me as document was IE7 and browser was IE10 compatibility. I added a http header in IIS: Name X-UA-Compatible Value IE=EmulateIE9
Now the page loads as document - IE9 standards, browser IE10 compatibility and all the previous issues are resolved.
Hope this helps.

You need just to follow those steps:
After which, if the build fails when you do Maven Install, it means there is no web.xml file under WEB-INF or some problem associated with it. it really works
You need to tell the query what value to pick for the other columns, MIN
or MAX
seem like suitable choices.
SELECT
U.NAME, MIN(P.PIC_ID)
FROM
USERS U,
PICTURES P,
POSTINGS P1
WHERE
U.EMAIL_ID = P1.EMAIL_ID AND
P1.PIC_ID = P.PIC_ID AND
P.CAPTION LIKE '%car%'
GROUP BY
U.NAME;
Using Python will be one easy way to achieve what you want.
I found one using Google.
"convert from json to csv using python" is an example.
My preferred method for centering blocks of information while maintaining responsiveness (mobile compatibility) is to place two empty span1
divs before and after the content you wish to center.
<div class="row-fluid">
<div class="span1">
</div>
<div class="span10">
<div class="hero-unit">
<h1>Reading Resources</h1>
<p>Read here...</p>
</div>
</div><!--/span-->
<div class="span1">

</div><!--/row-->
I based my answer on the title of your post only, as I don't know C# and didn't understand the given query. But in MySQL I suggest you try subselects. First get a set of primary keys of interesting columns then select data from those rows:
SELECT somecolumn, anothercolumn
FROM sometable
WHERE id IN (
SELECT min(id)
FROM sometable
GROUP BY somecolumn
);
You can try this query:
Select A.*, (select count(*) from Table1 where A.ID>=ID) as RowNo
from Table1 as A
order by A.ID

minimumFontSize

So use minimumScaleFactor

lbl.adjustsFontSizeToFitWidth = YES
lbl.minimumScaleFactor = 0.5
Swift 5
lbl.adjustsFontSizeToFitWidth = true
lbl.minimumScaleFactor = 0.5
noexcept
can dramatically improve performance of some operations. This does not happen at the level of generating machine code by the compiler, but by selecting the most effective algorithm: as others mentioned, you do this selection using function std::move_if_noexcept
. For instance, the growth of std::vector
(e.g., when we call reserve
) must provide a strong exception-safety guarantee. If it knows that T
's move constructor doesn't throw, it can just move every element. Otherwise it must copy all T
s. This has been described in detail in this post.
I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

curl -u username:password http://
curl -u username http://
From the documentation page:
-u, --user <user:password>
Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.
If you simply specify the user name, curl will prompt for a password.
The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.
When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.
When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.
To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.
If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".
If this option is used several times, the last one will be used.

Note that you do not need --basic
flag as it is the default.

You can use regular expressions for this, so I think this is what you want:
select t.*
from test t
where not regexp_like(sampletext, '.*[^a-zA-Z0-9 .{}\[\]].*')
I suggest creating a test app (for dev environment only) on https://developers.facebook.com/apps and set: Website with Facebook Login
property to your localhost:[port] settings.
this option will work fine with no need to change hosts.
remember to change the appId back to your production app once you go live.
Edit - in the latest fb version you'll find it under the settings
tab.

Difference between STATIC MEMORY ALLOCATION & DYNAMIC MEMORY ALLOCATION
Memory is allocated before the execution of the program begins
(During Compilation).
Memory is allocated during the execution of the program.
No memory allocation or deallocation actions are performed during Execution.
Memory Bindings are established and destroyed during the Execution.
Variables remain permanently allocated.
Allocated only when program unit is active.
Implemented using stacks and heaps.
Implemented using data segments.
Pointer is needed to accessing variables.
No need of Dynamically allocated pointers.
Faster execution than Dynamic.
Slower execution than static.
More memory Space required.
Less Memory space required.
It's limited in that you can't put statements in there. You can only put values(or things that return/evaluate to values), to return
This works ('a' is a static int within class Blah)
Blah.a=Blah.a<5?1:8;
(round brackets are impicitly between the equals and the question mark).
This doesn't work.
Blah.a = Blah.a < 4 ? Console.WriteLine("asdf") : Console.WriteLine("34er");
or
Blah.a = Blah.a < 4 ? MessageBox.Show("asdf") : MessageBox.Show("34er");
So you can only use the c# ternary operator for returning values. So it's not quite like a shortened form of an if. Javascript and perhaps some other languages let you put statements in there.
If you're targeting at or above iOS 8 or OS X 10.10, this just got a lot easier. The new NSDateComponentsFormatter
class allows you to convert a given NSTimeInterval
from its value in seconds to a localized string to show the user. For example:
Objective-C
NSTimeInterval interval = 326.4;
NSDateComponentsFormatter *componentFormatter = [[NSDateComponentsFormatter alloc] init];
componentFormatter.unitsStyle = NSDateComponentsFormatterUnitsStylePositional;
componentFormatter.zeroFormattingBehavior = NSDateComponentsFormatterZeroFormattingBehaviorDropAll;
NSString *formattedString = [componentFormatter stringFromTimeInterval:interval];
NSLog(@"%@",formattedString); // 5:26
Swift
let interval = 326.4
let componentFormatter = NSDateComponentsFormatter()
componentFormatter.unitsStyle = .Positional
componentFormatter.zeroFormattingBehavior = .DropAll
if let formattedString = componentFormatter.stringFromTimeInterval(interval) {
print(formattedString) // 5:26
}
NSDateCompnentsFormatter
also allows for this output to be in longer forms. More info can be found in NSHipster's NSFormatter article. And depending on what classes you're already working with (if not NSTimeInterval
), it may be more convenient to pass the formatter an instance of NSDateComponents
, or two NSDate
objects, which can be done as well via the following methods.
Objective-C
NSString *formattedString = [componentFormatter stringFromDate:<#(NSDate *)#> toDate:<#(NSDate *)#>];
NSString *formattedString = [componentFormatter stringFromDateComponents:<#(NSDateComponents *)#>];
Swift
if let formattedString = componentFormatter.stringFromDate(<#T##startDate: NSDate##NSDate#>, toDate: <#T##NSDate#>) {
// ...
}
if let formattedString = componentFormatter.stringFromDateComponents(<#T##components: NSDateComponents##NSDateComponents#>) {
// ...
}
It's important to understand that your code will sleep for 50 seconds between ending one loop, and starting the next...
A timer will call your loop every 50 seconds, which isn't exactly the same.
They're both valid, but a timer is probably what you're looking for here.
I ran into a very similar issue.
I needed to use an old 32-bit DLL within a Web Application that was being developed on a 64-bit machine. I registered the 32-bit DLL into the windows\sysWOW64 folder using the version of regsrv32 in that folder.
Calls to the third party DLL worked from unit tests in Visual Studio but failed from the Web Application hosted in IIS on the same machine with the 80040154 error.
Changing the application pool to "Enable 32-Bit Applications" resolved the issue.

Best practice would probably be to give your link an id

document.getElementById("yourFormId").submit();

This answer is all about authorization and it is a complement of my previous answer about authentication
Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.
@Secured
annotationBesides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.
Create an enumeration and define the roles according to your needs:
public enum Role {
ROLE_1,
ROLE_2,
ROLE_3
}
Change the @Secured
name binding annotation created before to support roles:
@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
Role[] value() default {};
}
And then annotate the resource classes and methods with @Secured
to perform the authorization. The method annotations will override the class annotations:
@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {
@GET
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response myMethod(@PathParam("id") Long id) {
// This method is not annotated with @Secured
// But it's declared within a class annotated with @Secured({Role.ROLE_1})
// So it only can be executed by the users who have the ROLE_1 role
...
}
@DELETE
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
@Secured({Role.ROLE_1, Role.ROLE_2})
public Response myOtherMethod(@PathParam("id") Long id) {
// This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
// The method annotation overrides the class annotation
// So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
...
}
}
Create a filter with the AUTHORIZATION
priority, which is executed after the AUTHENTICATION
priority filter defined previously.
The ResourceInfo
can be used to get the resource Method
and resource Class
that will handle the request and then extract the @Secured
annotations from them:
@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
// Get the resource class which matches with the requested URL
// Extract the roles declared by it
Class<?> resourceClass = resourceInfo.getResourceClass();
List<Role> classRoles = extractRoles(resourceClass);
// Get the resource method which matches with the requested URL
// Extract the roles declared by it
Method resourceMethod = resourceInfo.getResourceMethod();
List<Role> methodRoles = extractRoles(resourceMethod);
try {
// Check if the user is allowed to execute the method
// The method annotations override the class annotations
if (methodRoles.isEmpty()) {
checkPermissions(classRoles);
} else {
checkPermissions(methodRoles);
}
} catch (Exception e) {
requestContext.abortWith(
Response.status(Response.Status.FORBIDDEN).build());
}
}
// Extract the roles from the annotated element
private List<Role> extractRoles(AnnotatedElement annotatedElement) {
if (annotatedElement == null) {
return new ArrayList<Role>();
} else {
Secured secured = annotatedElement.getAnnotation(Secured.class);
if (secured == null) {
return new ArrayList<Role>();
} else {
Role[] allowedRoles = secured.value();
return Arrays.asList(allowedRoles);
}
}
}
private void checkPermissions(List<Role> allowedRoles) throws Exception {
// Check if the user contains one of the allowed roles
// Throw an Exception if the user has not permission to execute the method
}
}
If the user has no permission to execute the operation, the request is aborted with a 403
(Forbidden).
To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext
(which should be already set in the ContainerRequestContext
) or inject it using CDI, depending on the approach you go for.
If a @Secured
annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.
Alternatively to defining the roles in the @Secured
annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed
, @PermitAll
and @DenyAll
.
JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:
@DenyAll
on the method takes precedence over @RolesAllowed
and @PermitAll
on the class.@RolesAllowed
on the method takes precedence over @PermitAll
on the class.@PermitAll
on the method takes precedence over @RolesAllowed
on the class.@DenyAll
can't be attached to classes.@RolesAllowed
on the class takes precedence over @PermitAll
on the class.So an authorization filter that checks JSR-250 annotations could be like:
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
Method method = resourceInfo.getResourceMethod();
// @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
if (method.isAnnotationPresent(DenyAll.class)) {
refuseRequest();
}
// @RolesAllowed on the method takes precedence over @PermitAll
RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
return;
}
// @PermitAll on the method takes precedence over @RolesAllowed on the class
if (method.isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}
// @DenyAll can't be attached to classes
// @RolesAllowed on the class takes precedence over @PermitAll on the class
rolesAllowed =
resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
}
// @PermitAll on the class
if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}
// Authentication is required for non-annotated methods
if (!isAuthenticated(requestContext)) {
refuseRequest();
}
}
/**
* Perform authorization based on roles.
*
* @param rolesAllowed
* @param requestContext
*/
private void performAuthorization(String[] rolesAllowed,
ContainerRequestContext requestContext) {
if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
refuseRequest();
}
for (final String role : rolesAllowed) {
if (requestContext.getSecurityContext().isUserInRole(role)) {
return;
}
}
refuseRequest();
}
/**
* Check if the user is authenticated.
*
* @param requestContext
* @return
*/
private boolean isAuthenticated(final ContainerRequestContext requestContext) {
// Return true if the user is authenticated or false otherwise
// An implementation could be like:
// return requestContext.getSecurityContext().getUserPrincipal() != null;
}
/**
* Refuse the request.
*/
private void refuseRequest() {
throw new AccessDeniedException(
"You don't have permissions to perform this action.");
}
}
Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature
. If you use Jersey, you don't need to write your own filter, just use the existing implementation.
IIS was the main offender for me. My IIS was running and it restrains any new socket connections from opening.
The problem resolved for me by stopping IIS by running the command "iisreset -stop
"
Can't add a comment to the solution but that didn't work for me. The solution that worked for me was to use:
var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass)); return des.data.Count.ToString();
var val = ... //the value you want to check_x000D_
if(Number.isNaN(Number(val))){_x000D_
console.log("This is NOT a number!");_x000D_
}else{_x000D_
console.log("This IS a number!");_x000D_
}
_x000D_
Suppose you want to add those flags (better to declare them in a constant):
SET(GCC_COVERAGE_COMPILE_FLAGS "-fprofile-arcs -ftest-coverage")
SET(GCC_COVERAGE_LINK_FLAGS "-lgcov")
There are several ways to add them:
The easiest one (not clean, but easy and convenient, and works only for compile flags, C & C++ at once):
add_definitions(${GCC_COVERAGE_COMPILE_FLAGS})
Appending to corresponding CMake variables:
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}")
SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${GCC_COVERAGE_LINK_FLAGS}")
Using target properties, cf. doc CMake compile flag target property and need to know the target name.
get_target_property(TEMP ${THE_TARGET} COMPILE_FLAGS)
if(TEMP STREQUAL "TEMP-NOTFOUND")
SET(TEMP "") # Set to empty string
else()
SET(TEMP "${TEMP} ") # A space to cleanly separate from existing content
endif()
# Append our values
SET(TEMP "${TEMP}${GCC_COVERAGE_COMPILE_FLAGS}" )
set_target_properties(${THE_TARGET} PROPERTIES COMPILE_FLAGS ${TEMP} )
Right now I use method 2.
It's simple, use $.getJSON()

This may be off topic, but for those who are struggling on how to exactly change also the font of the button text (that was my case and Skatephone's answer helped me) here's how I did it (if you made buttons ind design mode):
First we need to have the button's string name "converted" (it's a foul way to explain, but straightforward) into java from the xml, and so we paste the aforementioned code into our MainActivity.java
IMPORTANT! place the code under the OnCreate method!
import android.widget.RemoteViews;
RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.my_layout);
remoteViews.setTextViewText(R.id.Counter, "Set button text here");
Keep in mind:
my_layout
has to be substituted with the xml file where your buttons are
Counter
has to be substituted with the id name of your button ("@+id/ButtonName"
)
if you want to change the button text just insert the text in place of "Set button text here"
here comes the part where you change the font:
Now that you "converted" from xml to java, you can set a Typeface method for TextView. Paste the following code exactly under the previous one just described above
TextView txt = (TextView) findViewById(R.id.text_your_text_view_id);
Typeface font = Typeface.createFromAsset(getAssets(), "fonts/MyFontName.ttf");
txt.setTypeface(font);
where in place of text_your_text_view_id
you put your button's id name (like as previous code) and in place of MyFontName.ttf
you put your desired font
WARNING! This assumes you already put your desired font into the assets/font folder. e.g. assets/fonts/MyFontName.ttf
jQuery's hasClass()
method returns a boolean (true/false) and not an element. Also, the parameter to be given to it is a class name and not a selector as such.
For ex: x.hasClass('error');
This problem is usually caused by writing to a connection that had already been closed by the peer. In this case it could indicate that the user cancelled the download for example.
Paste typically merges lines of multiple files, but it can also be used to convert individual lines of a file into a single line. The delimiter flag allows you to pass a x+x type equation to bc.
paste -s -d+ infile | bc
Alternatively, when piping from stdin,

I also get the same error in an ASP.NET application when I saved some unicode data (Hindi) in the Web.config file and saved it with "Unicode" encoding.
It fixed the error for me when I saved the Web.config file with "UTF-8" encoding.
I have the same error as this topic when I restore a new database using an old database. (using .bak gives the same error)
I Changed the name of old database by name of new database (same this picture). It worked.
Query has two syntax, the syntax you are using, last column represents orderBy, you just need to specify on what column you want to do orderBy +"ASC" (or) orderBy +"DESC"
Cursor c = scoreDb.query(DATABASE_TABLE, rank, null, null, null, null, yourColumn+" DESC");
Refer this documentation to understand more about query()
method.

It is a basic law that Strings in java are immutable and case sensitive.
This is how you should initialize the NSString
:
Swift 2.X or older
let datastring = NSString(data: fooData, encoding: NSUTF8StringEncoding)
Swift 3 or newer:
let datastring = NSString(data: fooData, encoding: String.Encoding.utf8.rawValue)
This doc explains the syntax.
This answer didn't work for me, I needed to run html decode on the string also. See
iconv('UTF-8', 'windows-1252', html_entity_decode($str));
Props go to emfi from html_entity_decode in FPDF(using tFPDF extention)
As of 2015, this is the best way (Java 8):
tourists.removeIf(Objects::isNull);
Note: This code will throw java.lang.UnsupportedOperationException
for fixed-size lists (such as created with Arrays.asList), including immutable lists.
To complement what @kieste has posted, which I think is the best way to have Maven build informations available in your code if you're using Spring-boot: the documentation at http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready-application-info is very useful.
You just need to activate actuators, and add the properties you need in your application.properties
or application.yml
Automatic property expansion using Maven
You can automatically expand info properties from the Maven project using resource filtering. If you use the spring-boot-starter-parent you can then refer to your Maven ‘project properties’ via @..@ placeholders, e.g.
project.artifactId=myproject
project.name=Demo
project.version=X.X.X.X
project.description=Demo project for info endpoint

The problem with most solutions here is that they rewind the stack. This can be a big problem in some cases.In this example I show how to use iterators in different way to simulate real sleep
In this example the generator is calling it's own next()
so once it's going, it's on his own.
var h=a();
h.next().value.r=h; //that's how U run it, best I came up with
//sleep without breaking stack !!!
function *a(){
var obj= {};
console.log("going to sleep....2s")
setTimeout(function(){obj.r.next();},2000)
yield obj;
console.log("woke up");
console.log("going to sleep no 2....2s")
setTimeout(function(){obj.r.next();},2000)
yield obj;
console.log("woke up");
console.log("going to sleep no 3....2s")
setTimeout(function(){obj.r.next();},2000)
yield obj;
console.log("done");
}
Depends on your use case but to summarise the difference:
ng-if
will remove elements from DOM. This means that all your handlers or anything else attached to those elements will be lost. For example, if you bound a click handler to one of child elements, when ng-if
evaluates to false, that element will be removed from DOM and your click handler will not work any more, even after ng-if
later evaluates to true and displays the element. You will need to reattach the handler.ng-show/ng-hide
does not remove the elements from DOM. It uses CSS styles to hide/show elements (note: you might need to add your own classes). This way your handlers that were attached to children will not be lost.ng-if
creates a child scope while ng-show/ng-hide
does notElements that are not in the DOM have less performance impact and your web app might appear to be faster when using ng-if
compared to ng-show/ng-hide
. In my experience, the difference is negligible. Animations are possible when using both ng-show/ng-hide
and ng-if
, with examples for both in the Angular documentation.
Ultimately, the question you need to answer is whether you can remove element from DOM or not?
As of modern version of Excel, there's the syntax with commas, not semicolons. I'm posting this answer for convenience of others so they don't have to replace the strings- We're all lazy... hrmp... human, right?
=CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-",DEC2HEX(RANDBETWEEN(0,4294967295),8),DEC2HEX(RANDBETWEEN(0,42949),4))
Or, if you like me dislike when a guid screams and shouts and you, we can go lower-cased like this.
=LOWER(CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-",DEC2HEX(RANDBETWEEN(0,4294967295),8),DEC2HEX(RANDBETWEEN(0,42949),4)))
Turgut gave the right solution. Just for clarity, you need to add close after writing.
function openWin()
{
myWindow=window.open('','','width=200,height=100');
myWindow.document.write("<p>This is 'myWindow'</p>");
myWindow.document.close(); //missing code
myWindow.focus();
myWindow.print();
}
This will print all the subdirectories of the current directory:
print [name for name in os.listdir(".") if os.path.isdir(name)]
I'm not sure what you're doing with split("-")
, but perhaps this code will help you find a solution?
If you want the full pathnames of the directories, use abspath
:
print [os.path.abspath(name) for name in os.listdir(".") if os.path.isdir(name)]
Note that these pieces of code will only get the immediate subdirectories. If you want sub-sub-directories and so on, you should use walk
as others have suggested.
Hope this is your structure:
<ul>
<li>
<div ><img.. /><p>text</p></div>
</li>
<li>
<div ><img.. /><p>text</p></div>
</li>
<li>
<div ><img.. /><p>text</p></div>
</li>
</ul>
By default, it will be add one after another row:
-----
-----
-----
if you want to make it vertical, just add float left to li, give width and height, make sure that content will not break the width:
| | |
| | |
li
{
display:block;
float:left;
width:300px; /* adjust */
height:150px; /* adjust */
padding: 5px; /*adjust*/
}
I am posting this answer to bring an updated solution to this problem. I am currently using Chrome 49 and no given answer work for this one. I am also looking for a solution working with other browsers and previous versions.
Put this code on the beginning of your form
<div style="display: none;">
<input type="text" autocomplete="new-password">
<input type="password" autocomplete="new-password">
</div>
Then, for your real password field, use
<input type="password" name="password" autocomplete="new-password">
Comment this answer if this is no longer working or if you get an issue with another browser or version.
Approved on:
1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib
Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.As explained in Django docs, initial
is not default
.
The initial value of a field is intended to be displayed in an HTML . But if the user delete this value, and finally send back a blank value for this field, the initial
value is lost. So you do not obtain what is expected by a default behaviour.
The default behaviour is : the value that validation process will take if data
argument do not contain any value for the field.
To implement that, a straightforward way is to combine initial
and clean_<field>()
:
class JournalForm(ModelForm):
tank = forms.IntegerField(widget=forms.HiddenInput(), initial=123)
(...)
def clean_tank(self):
if not self['tank'].html_name in self.data:
return self.fields['tank'].initial
return self.cleaned_data['tank']
These are escape characters which are used to manipulate string.
\t Insert a tab in the text at this point.
\b Insert a backspace in the text at this point.
\n Insert a newline in the text at this point.
\r Insert a carriage return in the text at this point.
\f Insert a form feed in the text at this point.
\' Insert a single quote character in the text at this point.
\" Insert a double quote character in the text at this point.
\\ Insert a backslash character in the text at this point.
Read more about them from here.

When generating CSR is possible to specify -ext attribute again to have it inserted in the CSR
keytool -certreq -file test.csr -keystore test.jks -alias testAlias -ext SAN=dns:test.example.com

I have had the same problem, but think I've got it under control now.
Are you using eclipse or command line or ??
When I use the command line, I think I did "seam clean" or "seam undeploy" or maybe even "seam restart" followed by "seam explode". I probably tried all of these at one time or another never bothering to look up what each one does.
The idea is to remove the deployed war file from TWO places
1. $JBOSS_HOME/server/default/deploy
2. $PROJECT_HOME/exploded_archives
I'm pretty sure "seam undeploy" removes the 1st and "seam clean" removes the 2nd.
When I use eclipse (I use the free one), I first turn off "Project/Build Automatically" Then when I am ready to deploy I do either Project/Build Project or Project/Build All depending on what I've changed. When I change xhtml, Build Project is sufficient. When I change java source Build All works. It's possible these do the same things and the difference is in my imagination, but some combination of this stuff will work for you.
You have to watch the output though. Occasionally the app does not get cleaned or undeployed. This would result in not seeing your change. Sometimes I shut down the server first and then rebuild/clean/deploy the project.
Hope this helps.

Try this It'll work perfect.
$('body.overflow-hidden').delegate('#skrollr-body','touchmove',function(e){
e.preventDefault();
console.log('Stop skrollrbody');
}).delegate('.mfp-auto-cursor .mfp-content','touchmove',function(e){
e.stopPropagation();
console.log('Scroll scroll');
});

I was having the same trouble with importing from Excel 2010 to Access, appending an "identical" table. Early on in the wizard it said not all my column names were valid, even though I checked them. It turns out that it saw an "empty" column with no column name. When I tried using the import wizard to create a new table instead, it worked. However, I noticed that it had added a blank column to the right of my data and called it "Field30". So I went back to the spreadsheet I was trying to import, selected the columns to the right of the data that I wanted, right-clicked and chose "clear contents." That did the trick and I was able to import the spreadsheet, appending it to my table.
This answer simply applies the type=date
attribute to the HTML input
element and relies on the browser to supply a date picker. Note that even in 2017, not all browsers provide their own date picker, so you may want to provide a fall back.
All you have to do is add attributes to the property in the view model. Example for variable Ldate
:
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
Public DateTime Ldate {get;set;}
Assuming you're using MVC 5 and Visual Studio 2013.
I sugges to use the Apache Commons CSV https://commons.apache.org/proper/commons-csv/
Here is one example:
Path currentRelativePath = Paths.get("");
String currentPath = currentRelativePath.toAbsolutePath().toString();
String csvFile = currentPath + "/pathInYourProject/test.csv";
Reader in;
Iterable<CSVRecord> records = null;
try
{
in = new FileReader(csvFile);
records = CSVFormat.EXCEL.withHeader().parse(in); // header will be ignored
}
catch (IOException e)
{
e.printStackTrace();
}
for (CSVRecord record : records) {
String line = "";
for ( int i=0; i < record.size(); i++)
{
if ( line == "" )
line = line.concat(record.get(i));
else
line = line.concat("," + record.get(i));
}
System.out.println("read line: " + line);
}
It automaticly recognize , and " but not ; (maybe it can be configured...).
My example file is:
col1,col2,col3
val1,"val2",val3
"val4",val5
val6;val7;"val8"
And output is:
read line: val1,val2,val3
read line: val4,val5
read line: val6;val7;"val8"
Last line is considered like one value.
Since Joda is getting faded, someone might want to convert LocaltDate
to LocalDateTime
in Java 8. In Java 8 LocalDateTime
it will give a way to create a LocalDateTime
instance using a LocalDate
and LocalTime
. Check here.
public static LocalDateTime of(LocalDate date, LocalTime time)
Sample would be,
// just to create a sample LocalDate
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyyMMdd");
LocalDate ld = LocalDate.parse("20180306", dtf);
// convert ld into a LocalDateTime
// We need to specify the LocalTime component here as well, it can be any accepted value
LocalDateTime ldt = LocalDateTime.of(ld, LocalTime.of(0,0)); // 2018-03-06T00:00
Just for reference, For getting the epoch seconds below can be used,
ZoneId zoneId = ZoneId.systemDefault();
long epoch = ldt.atZone(zoneId).toEpochSecond();
// If you only care about UTC
long epochUTC = ldt.toEpochSecond(ZoneOffset.UTC);
As of Xcode 10+, and according to the WWDC 2018 session 223, "Embracing Algorithms," a good method going forward will be mutating func removeAll(where predicate: (Element) throws -> Bool) rethrows
Apple's example:
var phrase = "The rain in Spain stays mainly in the plain."
let vowels: Set<Character> = ["a", "e", "i", "o", "u"]
phrase.removeAll(where: { vowels.contains($0) })
// phrase == "Th rn n Spn stys mnly n th pln."
So in the OP's example, removing animals[2], "chimps":
var animals = ["cats", "dogs", "chimps", "moose"]
animals.removeAll(where: { $0 == "chimps" } )
// or animals.removeAll { $0 == "chimps" }
This method may be preferred because it scales well (linear vs quadratic), is readable and clean. Keep in mind that it only works in Xcode 10+, and as of writing this is in Beta.
An update to Martin Alléus's answer, to get the full screen whether it is a phone or a iPad without having to hard code:
CGRect rect = [[UIScreen mainScreen] bounds];
CGSize screenSize = rect.size;
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,screenSize.width,screenSize.height)];
NSString *path = [[NSBundle mainBundle] pathForResource:@"pdf" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];
[self.view addSubview:webView];
Try adding -l to the nm flags in order to get the source of each symbol. If the library is compiled with debugging info (gcc -g) this should be the source file and line number. As Konrad said, the object file / static library is probably unknown at this point.
Because you can ask the server to prepend a prefix to the returned JSON object. E.g
function_prefix(json_object);
in order for the browser to eval
"inline" the JSON string as an expression. This trick makes it possible for the server to "inject" javascript code directly in the Client browser and this with bypassing the "same origin" restrictions.
In other words, you can achieve cross-domain data exchange.
Normally, XMLHttpRequest
doesn't permit cross-domain data-exchange directly (one needs to go through a server in the same domain) whereas:
<script src="some_other_domain/some_data.js&prefix=function_prefix
>` one can access data from a domain different than from the origin.
Also worth noting: even though the server should be considered as "trusted" before attempting that sort of "trick", the side-effects of possible change in object format etc. can be contained. If a function_prefix
(i.e. a proper js function) is used to receive the JSON object, the said function can perform checks before accepting/further processing the returned data.
I encountered this problem when the .idea folder was accidentally added to SVN version control. When I took an update --- blooey! I subsequently removed the .idea folder from version control.
char* str = "blablabla";
You should not modify this string at all. It resides in implementation defined read only region. Modifying it causes Undefined Behavior.
You need a char array not a string literal.
Good Read:
What is the difference between char a[] = "string"; and char *p = "string";
If you want to use @OverZealous' answer (https://stackoverflow.com/a/21806974/1019307) in Typescript, you need to import
instead of require
:
import * as debug from 'gulp-debug';
...
return gulp.src('./examples/*.html')
.pipe(debug({title: 'example src:'}))
.pipe(gulp.dest('./build'));
(I also added a title
).
I ran into this issue because in the dependency injection setup I was missing a dependency of a repository that is a dependency of a controller:
services.AddScoped<IDependencyOne, DependencyOne>(); <-- I was missing this line!
services.AddScoped<IDependencyTwoThatIsDependentOnDependencyOne, DependencyTwoThatIsDependentOnDependencyOne>();
In my case it was POST submission of a json to be processed and get a return value. I cross checked logs of my app server with and without nginx. What i got was my location was not getting appended to proxy_pass url and the version of HTTP protocol version is different.
My earlier location block was
location /xxQuery {
proxy_method POST;
proxy_pass http://127.0.0.1:xx00/;
client_max_body_size 10M;
}
I changed it to
location /xxQuery {
proxy_method POST;
proxy_http_version 1.1;
proxy_pass http://127.0.0.1:xx00/xxQuery;
client_max_body_size 10M;
}
It worked.
struct.calcsize("P")
returns size of the bytes required to store a single pointer. On a 32-bit system, it would return 4 bytes. On a 64-bit system, it would return 8 bytes.
So the following would return 32
if you're running 32-bit python and 64
if you're running 64-bit python:
Python 2
import struct;print struct.calcsize("P") * 8
Python 3
import struct;print(struct.calcsize("P") * 8)
First install "Microsoft ASP.NET Web API Client" nuget package:
PM > Install-Package Microsoft.AspNet.WebApi.Client
Then use the following function to post your data:
public static async Task<TResult> PostFormUrlEncoded<TResult>(string url, IEnumerable<KeyValuePair<string, string>> postData)
{
using (var httpClient = new HttpClient())
{
using (var content = new FormUrlEncodedContent(postData))
{
content.Headers.Clear();
content.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
HttpResponseMessage response = await httpClient.PostAsync(url, content);
return await response.Content.ReadAsAsync<TResult>();
}
}
}
And this is how to use it:
TokenResponse tokenResponse =
await PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData);
or
TokenResponse tokenResponse =
(Task.Run(async ()
=> await PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData)))
.Result
or (not recommended)
TokenResponse tokenResponse =
PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData).Result;
Yes, substring
works great:
stringTruncate('Hello world', 5); //output "Hello..."
stringTruncate('Hello world', 20);//output "Hello world"
var stringTruncate = function(str, length){
var dots = str.length > length ? '...' : '';
return str.substring(0, length)+dots;
};
You could use find
to solve your problem
const data = [{"a": 1}, {"b": 2}]
const item = {"b": 2}
find(data, item)
// > true
In options object you have used "=" sign to assign value to port but we have to use ":" to assign values to properties in object when using object literal to create an object i.e."{}" ,these curly brackets. Even when you use function expression or create an object inside object you have to use ":" sign. for e.g.:
var rishabh = {
class:"final year",
roll:123,
percent: function(marks1, marks2, marks3){
total = marks1 + marks2 + marks3;
this.percentage = total/3 }
};
john.percent(85,89,95);
console.log(rishabh.percentage);
here we have to use commas "," after each property. but you can use another style to create and initialize an object.
var john = new Object():
john.father = "raja"; //1st way to assign using dot operator
john["mother"] = "rani";// 2nd way to assign using brackets and key must be string
I am late for the party. Try replacing as below, mine worked perfectly- "DOMDocument" to "MSXML2.DOMDocument60" "XMLHTTP" to "MSXML2.XMLHTTP60"
Swift 2.0
Well I worked out. Have a look. Made a ViewController in StoryBoard. Associated with PopOverViewController class.
import UIKit
class PopOverViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.preferredContentSize = CGSizeMake(200, 200)
self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Done, target: self, action: "dismiss:")
}
func dismiss(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
}
}
See ViewController:
// ViewController.swift
import UIKit
class ViewController: UIViewController, UIPopoverPresentationControllerDelegate
{
func showPopover(base: UIView)
{
if let viewController = self.storyboard?.instantiateViewControllerWithIdentifier("popover") as? PopOverViewController {
let navController = UINavigationController(rootViewController: viewController)
navController.modalPresentationStyle = .Popover
if let pctrl = navController.popoverPresentationController {
pctrl.delegate = self
pctrl.sourceView = base
pctrl.sourceRect = base.bounds
self.presentViewController(navController, animated: true, completion: nil)
}
}
}
override func viewDidLoad(){
super.viewDidLoad()
}
@IBAction func onShow(sender: UIButton)
{
self.showPopover(sender)
}
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return .None
}
}
Note: The func showPopover(base: UIView) method should be placed before ViewDidLoad. Hope it helps !

If you need to position an element relative to its containing element first you need to add position: relative
to the container element. The child element you want to position relatively to the parent has to have position: absolute
. The way that absolute positioning works is that it is done relative to the first relatively (or absolutely) positioned parent element. In case there is no relatively positioned parent, the element will be positioned relative to the root element (directly to the HTML element).
So if you want to position your child element to the top left of the parent container, you should do this:
.parent {
position: relative;
}
.child {
position: absolute;
top: 0;
left: 0;
}

File -> Invalidate Caches / Restart did the trick for me (which is always a good first try)
Well I did not read correctly the man echo
page for this.
echo had 2 options that could do this if I added a 3rd escape character.
The 2 options are -n
and -e
.
-n
will not output the trailing newline. So that saves me from going to a new line each time I echo something.
-e
will allow me to interpret backslash escape symbols.
Guess what escape symbol I want to use for this: \r
. Yes, carriage return would send me back to the start and it will visually look like I am updating on the same line.
So the echo line would look like this:
echo -ne "Movie $movies - $dir ADDED!"\\r
I had to escape the escape symbol so Bash would not kill it. that is why you see 2 \
symbols in there.
As mentioned by William, printf
can also do similar (and even more extensive) tasks like this.
Has anyone considered using int.Parse()
and int.TryParse()
like this
int bar = int.Parse(foo.ToString());
Even better like this
int bar;
if (!int.TryParse(foo.ToString(), out bar))
{
//Do something to correct the problem
}
It's a lot safer and less error prone
Change the number of @grid-columns
. Then use -offset
. Changing the number of columns will allow you to control the amount of space between columns. E.g.
variables.less (approx line 294).
@grid-columns: 20;
someName.html
<div class="row">
<div class="col-md-4 col-md-offset-1">First column</div>
<div class="col-md-13 col-md-offset-1">Second column</div>
</div>
I wasted couple of hours on the same issue. In my case, I had to reset_index() of a dataframe before using apply function. Before merging, or looking up from another indexed dataset, you need to reset the index as 1 dataset can have only 1 Index.
what @yabin ya says is a cool solution, just remind you that: if u still get the same problem,go to Settings-Version Control-GitHub and uncheck the Clone git repositories using ssh
.
I made a command line tool to activate the profiler activity and see the logs in a "tail"able way: "mongotail".
But the more interesting feature (also like tail
) is to see the changes in "real time" with the -f
option, and occasionally filter the result with grep
to find a particular operation.
See documentation and installation instructions in: https://github.com/mrsarm/mongotail
You could just put the letter X in the HTML inside the div and then style it with css.
See JSFiddle: http://jsfiddle.net/uSwbN/
HTML:
<div id="orangeBox">
<span id="x">X</span>
</div>
CSS:
#orangeBox {
background: #f90;
color: #fff;
font-family: 'Helvetica', 'Arial', sans-serif;
font-size: 2em;
font-weight: bold;
text-align: center;
width: 40px;
height: 40px;
border-radius: 5px;
}
There is builtin procedure to check dependents:
For an example ,
Execute sp_depends @objname=N'ssc.RegDash_RoutingAct'
I did get this working. Didn't use any usb cable.
Run it. That will set ip and port; Then in dos
cd C:\Program Files\Android\android-sdk\platform-tools adb connect "192.168.2.22:8000 "enter"
Connected.
I was getting the same error with a service access. It was working in browser, but wasnt working when I try to access it in my asp.net/c# application. I changed application pool from appPoolIdentity to NetworkService, and it start working. Seems like a permission issue to me.
There will be of course some rounding errors, so this is not perfect, but this is what I use generally for applications, which don't require high precision. If you wanted to make this more accurate, you could add an extra argument to specify how to handle rounding errors. Perhaps passing a rounding function might make this extensible and allow the programmer to specify how to handle rounding errors.
arange = lambda start, stop, step: [i + step * i for i in range(int((stop - start) / step))]
If I write:
arange(0, 1, 0.1)
It will output:
[0.0, 0.1, 0.2, 0.30000000000000004, 0.4, 0.5, 0.6000000000000001, 0.7000000000000001, 0.8, 0.9]
Here are the two main approaches. I prefer this one for its readability:
bar <- subset(foo, location == "there")
Note that you can string together many conditionals with &
and |
to create complex subsets.
The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there"
returns a vector of T
and F
values that is the same length as the rows of foo
. You can do this to return only rows where the condition returns true.
foo[foo$location == "there", ]
That's because if a class is abstract, then by definition you are required to create subclasses of it to instantiate. The subclasses will be required (by the compiler) to implement any interface methods that the abstract class left out.
Following your example code, try making a subclass of AbstractThing
without implementing the m2
method and see what errors the compiler gives you. It will force you to implement this method.
For Windows, you can use winsound. It's built in
import winsound
winsound.PlaySound('sound.wav', winsound.SND_FILENAME)
You should be able to use ossaudiodev for linux:
from wave import open as waveOpen
from ossaudiodev import open as ossOpen
s = waveOpen('tada.wav','rb')
(nc,sw,fr,nf,comptype, compname) = s.getparams( )
dsp = ossOpen('/dev/dsp','w')
try:
from ossaudiodev import AFMT_S16_NE
except ImportError:
from sys import byteorder
if byteorder == "little":
AFMT_S16_NE = ossaudiodev.AFMT_S16_LE
else:
AFMT_S16_NE = ossaudiodev.AFMT_S16_BE
dsp.setparameters(AFMT_S16_NE, nc, fr)
data = s.readframes(nf)
s.close()
dsp.write(data)
dsp.close()

With webpack you can put env-specific config into the externals
field in webpack.config.js
externals: {
'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? {
serverUrl: "https://myserver.com"
} : {
serverUrl: "http://localhost:8090"
})
}
If you want to store the configs in a separate JSON file, that's possible too, you can require that file and assign to Config
:
externals: {
'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? require('./config.prod.json') : require('./config.dev.json'))
}
Then in your modules, you can use the config:
var Config = require('Config')
fetchData(Config.serverUrl + '/Enterprises/...')
For React:
import Config from 'Config';
axios.get(this.app_url, {
'headers': Config.headers
}).then(...);
Not sure if it covers your use case but it's been working pretty well for us.
The following simply returns 4 as an answer. When you replace the add expressions for strings it returns the first string.
Function StartingMain {
$a = 1 + 3
$b = 2 + 5
$c = 3 + 7
Return $a
}
Function StartingEnd($b) {
Write-Host $b
}
StartingEnd(StartingMain)
This can also be done for an array. The example below will return "Text 2"
Function StartingMain {
$a = ,@("Text 1","Text 2","Text 3")
Return $a
}
Function StartingEnd($b) {
Write-Host $b[1]
}
StartingEnd(StartingMain)
Note that you have to call the function below the function itself. Otherwise, the first time it runs it will return an error that it doesn't know what "StartingMain" is.
Varchar has its own limits. Maybe try changing datatype to text.!
To load python code reliably, have that code in a module, and that module installed in python's library.
Installed modules can always be loaded from the top level namespace with import <name>
There is a great sample project available officially here: https://github.com/pypa/sampleproject
Basically, you can have a directory structure like so:
the_foo_project/
setup.py
bar.py # `import bar`
foo/
__init__.py # `import foo`
baz.py # `import foo.baz`
faz/ # `import foo.faz`
__init__.py
daz.py # `import foo.faz.daz` ... etc.
.
Be sure to declare your setuptools.setup()
in setup.py
,
official example: https://github.com/pypa/sampleproject/blob/master/setup.py
In our case we probably want to export bar.py
and foo/__init__.py
, my brief example:
#!/usr/bin/env python3
import setuptools
setuptools.setup(
...
py_modules=['bar'],
packages=['foo'],
...
entry_points={},
# Note, any changes to your setup.py, like adding to `packages`, or
# changing `entry_points` will require the module to be reinstalled;
# `python3 -m pip install --upgrade --editable ./the_foo_project
)
.
Now we can install our module into the python library;
with pip, you can install the_foo_project
into your python library in edit mode,
so we can work on it in real time
python3 -m pip install --editable=./the_foo_project
# if you get a permission error, you can always use
# `pip ... --user` to install in your user python library
.
Now from any python context, we can load our shared py_modules and packages
#!/usr/bin/env python3
import bar
import foo
print(dir(bar))
print(dir(foo))
Both System.Timers.Timer
and System.Threading.Timer
will work for services.
The timers you want to avoid are System.Web.UI.Timer
and System.Windows.Forms.Timer
, which are respectively for ASP applications and WinForms. Using those will cause the service to load an additional assembly which is not really needed for the type of application you are building.
Use System.Timers.Timer
like the following example (also, make sure that you use a class level variable to prevent garbage collection, as stated in Tim Robinson's answer):
using System;
using System.Timers;
public class Timer1
{
private static System.Timers.Timer aTimer;
public static void Main()
{
// Normally, the timer is declared at the class level,
// so that it stays in scope as long as it is needed.
// If the timer is declared in a long-running method,
// KeepAlive must be used to prevent the JIT compiler
// from allowing aggressive garbage collection to occur
// before the method ends. (See end of method.)
//System.Timers.Timer aTimer;
// Create a timer with a ten second interval.
aTimer = new System.Timers.Timer(10000);
// Hook up the Elapsed event for the timer.
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
// Set the Interval to 2 seconds (2000 milliseconds).
aTimer.Interval = 2000;
aTimer.Enabled = true;
Console.WriteLine("Press the Enter key to exit the program.");
Console.ReadLine();
// If the timer is declared in a long-running method, use
// KeepAlive to prevent garbage collection from occurring
// before the method ends.
//GC.KeepAlive(aTimer);
}
// Specify what you want to happen when the Elapsed event is
// raised.
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
}
}
/* This code example produces output similar to the following:
Press the Enter key to exit the program.
The Elapsed event was raised at 5/20/2007 8:42:27 PM
The Elapsed event was raised at 5/20/2007 8:42:29 PM
The Elapsed event was raised at 5/20/2007 8:42:31 PM
...
*/
If you choose System.Threading.Timer
, you can use as follows:
using System;
using System.Threading;
class TimerExample
{
static void Main()
{
AutoResetEvent autoEvent = new AutoResetEvent(false);
StatusChecker statusChecker = new StatusChecker(10);
// Create the delegate that invokes methods for the timer.
TimerCallback timerDelegate =
new TimerCallback(statusChecker.CheckStatus);
// Create a timer that signals the delegate to invoke
// CheckStatus after one second, and every 1/4 second
// thereafter.
Console.WriteLine("{0} Creating timer.\n",
DateTime.Now.ToString("h:mm:ss.fff"));
Timer stateTimer =
new Timer(timerDelegate, autoEvent, 1000, 250);
// When autoEvent signals, change the period to every
// 1/2 second.
autoEvent.WaitOne(5000, false);
stateTimer.Change(0, 500);
Console.WriteLine("\nChanging period.\n");
// When autoEvent signals the second time, dispose of
// the timer.
autoEvent.WaitOne(5000, false);
stateTimer.Dispose();
Console.WriteLine("\nDestroying timer.");
}
}
class StatusChecker
{
int invokeCount, maxCount;
public StatusChecker(int count)
{
invokeCount = 0;
maxCount = count;
}
// This method is called by the timer delegate.
public void CheckStatus(Object stateInfo)
{
AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
Console.WriteLine("{0} Checking status {1,2}.",
DateTime.Now.ToString("h:mm:ss.fff"),
(++invokeCount).ToString());
if(invokeCount == maxCount)
{
// Reset the counter and signal Main.
invokeCount = 0;
autoEvent.Set();
}
}
}
Both examples comes from the MSDN pages.
This is how, I have been using a random user agent from a list of nearlly 1000 fake user agents
from random_user_agent.user_agent import UserAgent
from random_user_agent.params import SoftwareName, OperatingSystem
software_names = [SoftwareName.ANDROID.value]
operating_systems = [OperatingSystem.WINDOWS.value, OperatingSystem.LINUX.value, OperatingSystem.MAC.value]
user_agent_rotator = UserAgent(software_names=software_names, operating_systems=operating_systems, limit=1000)
# Get list of user agents.
user_agents = user_agent_rotator.get_user_agents()
user_agent_random = user_agent_rotator.get_random_user_agent()
Example
print(user_agent_random)

What about this:
var txt="";
var nyc = {
fullName: "New York City",
mayor: "Michael Bloomberg",
population: 8000000,
boroughs: 5
};
for (var x in nyc){
txt += nyc[x];
}
If you only need to share data between views/scopes/controllers, the easiest way is to store it in $rootScope. However, if you need a shared function, it is better to define a service to do that.
You can also use reduceRight.
[1,2,3,4,5,6].reduceRight(function(a,b){return a+b;})
which results output as 21.
Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/ReduceRight
i've had to do this quite often. i have a directive and need to do some jquery stuff after model stuff is fully loaded into the DOM. so i put my logic in the link: function of the directive and wrap the code in a setTimeout(function() { ..... }, 1); the setTimout will fire after the DOM is loaded and 1 milisecond is the shortest amount of time after DOM is loaded before code would execute. this seems to work for me but i do wish angular raised an event once a template was done loading so that directives used by that template could do jquery stuff and access DOM elements. hope this helps.
feof()
indicates if one has tried to read past the end of file. That means it has little predictive effect: if it is true, you are sure that the next input operation will fail (you aren't sure the previous one failed BTW), but if it is false, you aren't sure the next input operation will succeed. More over, input operations may fail for other reasons than the end of file (a format error for formatted input, a pure IO failure -- disk failure, network timeout -- for all input kinds), so even if you could be predictive about the end of file (and anybody who has tried to implement Ada one, which is predictive, will tell you it can complex if you need to skip spaces, and that it has undesirable effects on interactive devices -- sometimes forcing the input of the next line before starting the handling of the previous one), you would have to be able to handle a failure.
So the correct idiom in C is to loop with the IO operation success as loop condition, and then test the cause of the failure. For instance:
while (fgets(line, sizeof(line), file)) {
/* note that fgets don't strip the terminating \n, checking its
presence allow to handle lines longer that sizeof(line), not showed here */
...
}
if (ferror(file)) {
/* IO failure */
} else if (feof(file)) {
/* format error (not possible with fgets, but would be with fscanf) or end of file */
} else {
/* format error (not possible with fgets, but would be with fscanf) */
}
Same problem, different solution.
One line in the PHP file was printing out XML headers (which use the same begin/end tags as PHP). Looks like the code within these tags set the encoding, and was executed within PHP which resulted in the strange characters. Either way here's the solution:
# Original
$xml_string = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
# fixed
$xml_string = "<" . "?xml version=\"1.0\" encoding=\"UTF-8\"?" . ">";
private void listView1_MouseDown(object sender, MouseEventArgs e)
{
li = listView1.GetItemAt(e.X, e.Y);
X = e.X;
Y = e.Y;
}
private void listView1_MouseUp(object sender, MouseEventArgs e)
{
int nStart = X;
int spos = 0;
int epos = listView1.Columns[1].Width;
for (int i = 0; i < listView1.Columns.Count; i++)
{
if (nStart > spos && nStart < epos)
{
subItemSelected = i;
break;
}
spos = epos;
epos += listView1.Columns[i].Width;
}
li.SubItems[subItemSelected].Text = "9";
}
Another way to do this is to use "Copy Database" feature:
Find by right clicking the source database > "Tasks" > "Copy Database".
You can copy the database to a lower version of SQL Server Instance. This worked for me from a SQL Server 2008 R2 (SP1) - 10.50.2789.0 to Microsoft SQL Server 2008 (SP2) - 10.0.3798.0
If you are using a linux system you can get a random number out of /dev/random or /dev/urandom. Be carefull /dev/random will block if there are not enough random numbers available. If you need speed over randomness use /dev/urandom.
These "files" will be filled with random numbers generated by the operating system. It depends on the implementation of /dev/random on your system if you get true or pseudo random numbers. True random numbers are generated with help form noise gathered from device drivers like mouse, hard drive, network.
You can get random numbers from the file with dd
Assuming you mean "list" where you say "array", you can do
if item in my_list:
# whatever
This works for any collection, not just for lists. For dictionaries, it checks whether the given key is present in the dictionary.
Note also that you can only use unload()
once. If you use it a second time without rerunning library()
, y'll get the not very informative error message invalid 'name' argument:
library(vegan)
#> Loading required package: permute
#> Loading required package: lattice
#> This is vegan 2.5-6
detach("package:vegan", unload=TRUE)
detach("package:vegan", unload=TRUE)
#> Error in detach("package:vegan", unload = TRUE): invalid 'name' argument
Created on 2020-05-09 by the reprex package (v0.3.0)
At least one item in your list is either not three dimensional, or its second or third dimension does not match the other elements. If only the first dimension does not match, the arrays are still matched, but as individual objects, no attempt is made to reconcile them into a new (four dimensional) array. Some examples are below:
That is, the offending element's shape != (?, 224, 3)
,
or ndim != 3
(with the ?
being non-negative integer).
That is what is giving you the error.
You'll need to fix that, to be able to turn your list into a four (or three) dimensional array. Without context, it is impossible to say if you want to lose a dimension from the 3D items or add one to the 2D items (in the first case), or change the second or third dimension (in the second case).
Here's an example of the error:
>>> a = [np.zeros((224,224,3)), np.zeros((224,224,3)), np.zeros((224,224))]
>>> np.array(a)
ValueError: could not broadcast input array from shape (224,224,3) into shape (224,224)
or, different type of input, but the same error:
>>> a = [np.zeros((224,224,3)), np.zeros((224,224,3)), np.zeros((224,224,13))]
>>> np.array(a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: could not broadcast input array from shape (224,224,3) into shape (224,224)
Alternatively, similar but with a different error message:
>>> a = [np.zeros((224,224,3)), np.zeros((224,224,3)), np.zeros((224,100,3))]
>>> np.array(a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: could not broadcast input array from shape (224,224,3) into shape (224)
But the following will work, albeit with different results than (presumably) intended:
>>> a = [np.zeros((224,224,3)), np.zeros((224,224,3)), np.zeros((10,224,3))]
>>> np.array(a)
# long output omitted
>>> newa = np.array(a)
>>> newa.shape
3 # oops
>>> newa.dtype
dtype('O')
>>> newa[0].shape
(224, 224, 3)
>>> newa[1].shape
(224, 224, 3)
>>> newa[2].shape
(10, 224, 3)
>>>

I developed a method that slightly beats memcmp()
(plinth's answer) and very slighly beats EqualBytesLongUnrolled()
(Arek Bulski's answer) on my PC. Basically, it unrolls the loop by 4 instead of 8.
Update 30 Mar. 2019:
Starting in .NET core 3.0, we have SIMD support!
This solution is fastest by a considerable margin on my PC:

To wrap text in the label control, change the the template of label as follows:
<Style x:Key="ErrorBoxStyle" TargetType="{x:Type Label}">
<Setter Property="BorderBrush" Value="#FFF08A73"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="Red"/>
<Setter Property="Background" Value="#FFFFE3DF"/>
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Padding" Value="5"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Top"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Label}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true" CornerRadius="5" HorizontalAlignment="Stretch">
<TextBlock TextWrapping="Wrap" Text="{TemplateBinding Content}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Those are not files (they don't exist on disk) - they are just names under which some HTTP handlers are registered.
Take a look at the web.config
in .NET Framework's directory (e.g. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config
):
<configuration>
<system.web>
<httpHandlers>
<add path="eurl.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
<add path="trace.axd" verb="*" type="System.Web.Handlers.TraceHandler" validate="True" />
<add path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" validate="True" />
<add verb="*" path="*_AppService.axd" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False" />
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False"/>
<add path="*.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
</httpHandlers>
</system.web>
<configuration>
You can register your own handlers with a whatever.axd
name in your application's web.config
. While you can bind your handlers to whatever names you like, .axd
has the upside of working on IIS6 out of the box by default (IIS6 passes requests for *.axd
to the ASP.NET runtime by default). Using an arbitrary path for the handler, like Document.pdf
(or really anything except ASP.NET-specific extensions), requires more configuration work. In IIS7 in integrated pipeline mode this is no longer a problem, as all requests are processed by the ASP.NET stack.
Here is pure Bootstrap 4 with CSS 3 solution.
<div class="modal fade2" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
</div>
<div class="modal-body">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal">OK</button>
</div>
</div>
</div>
</div>
.fade2 {
transform: scale(0.9);
opacity: 0;
transition: all .2s linear;
display: block !important;
}
.fade2.show {
opacity: 1;
transform: scale(1);
}
$('#exampleModal').modal();
function afterModalTransition(e) {
e.setAttribute("style", "display: none !important;");
}
$('#exampleModal').on('hide.bs.modal', function (e) {
setTimeout( () => afterModalTransition(this), 200);
})
Full example here.
Maybe it will help someone.

Since you haven't initialized car
yet so it has no existence in JVM(Java Virtual Machine) so you have to initialize it first.
For instance :
car = new String{"Porsche","Lamborghini"};
Now your code will run fine.
INPUT:
String car [];
car = new String{"Porsche","Lamborghini"};
System.out.println(car.length);
OUTPUT:
2
Just use a specific variable for that.
$ cat Makefile
all:
echo foo | gcc $(USER_DEFINES) -E -xc -
$ make USER_DEFINES="-Dfoo=one"
echo foo | gcc -Dfoo=one -E -xc -
...
one
$ make USER_DEFINES="-Dfoo=bar"
echo foo | gcc -Dfoo=bar -E -xc -
...
bar
$ make
echo foo | gcc -E -xc -
...

Like: .align-item-center
and .justify-content-center
We can use these classes identically for all device view.
Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center
.text-center class is used to align text in center.

Search+ is a notepad++ plugin that does exactly this. You can download it from here and install it following the steps mentioned here
Feel free to post any issues/suggestions here.

ChartJS 2.6 supports data reference replacement (see Note in update(config) documentation). So when you have your Chart, you could basically just do this:
myChart.data.labels = ['1am', '2am', '3am', '4am'];
myChart.data.datasets[0].data = [0, 12, 35, 36];
myChart.update();
It doesn't do the animation you'd get from adding points, but existing points on the graph will be animated.
You can start your container with the flag -P
. This "assigns" a random port to the exposed port of your image.
With docker port <container id>
you can see the randomly choosen port. Access is then possible via localhost:port
.
That looks fine, unless you want to pass it as Model string
public class HomeController : Controller
{
public ActionResult Index()
{
string model = "<HTML></HTML>";
return View(model);
}
}
@model string
@{
ViewBag.Title = "Index";
}
@Html.Raw(Model)
Update all your code that calls load
function like,
$(window).load(function() { ... });
To
$(window).on('load', function() { ... });
jquery.js:9612 Uncaught TypeError: url.indexOf is not a function
This error message comes from jQuery.fn.load
function.
I've come across the same issue on my application. After some digging, I found this statement in jQuery blog,
.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.
I simply just change how my jQuery objects call the load
function like above. And everything works as expected.
To conditionally control view of Template/Command fields, use RowDataBound event of Gridview, like:
<asp:GridView ID="gv1" OnRowDataBound="gv1_RowDataBound"
runat="server" AutoGenerateColumns="False" DataKeyNames="Id" >
<Columns>
...
<asp:TemplateField HeaderText="Order Status"
HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label ID="lblOrderStatus" runat="server"
Text='<%# Bind("OrderStatus") %>'></asp:Label>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Center"></HeaderStyle>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
...
<asp:CommandField ShowSelectButton="True" SelectText="Select" />
</Columns>
</asp:GridView>
and following:
protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Label lblOrderStatus=(Label) e.Row.Cells[4].FindControl("lblOrderStatus");
if (lblOrderStatus.Text== "Ordered")
{
lblOrderStatus.ForeColor = System.Drawing.Color.DarkBlue;
LinkButton bt = (LinkButton)e.Row.Cells[5].Controls[0];
bt.Visible = false;
e.Row.BackColor = System.Drawing.Color.LightGray;
}
}
Anyone who is using pipenv (and you should!) can simply use these two commands — without having the venv activated:
rm -rf `pipenv --venv` # remove the broken venv
pipenv install --dev # reinstall the venv from pipfile
You can do this by using properties of textfield from Attribute inspector
Tap on Your Textfield from storyboard and go to Attribute inspector , and just check the checkbox of "Secure Text Entry" SS is added for graphical overview to achieve same
