I wonder why no one have mentioned this simple pattern? :
(function(next) {
//do something
next()
}(function() {
//do some more
}))
Using timeouts just for blindly waiting is bad practice; and involving promises just adds more complexity to the code. In OP's case:
(function(next) {
for(i=0;i<x;i++){
// do something
if (i==x-1) next()
}
}(function() {
// now wait for firstFunction to finish...
// do something else
}))

I'm going to expand your question a bit and also include the compile function.
compile function - use for template DOM manipulation (i.e., manipulation of tElement = template element), hence manipulations that apply to all DOM clones of the template associated with the directive. (If you also need a link function (or pre and post link functions), and you defined a compile function, the compile function must return the link function(s) because the 'link'
attribute is ignored if the 'compile'
attribute is defined.)
link function - normally use for registering listener callbacks (i.e., $watch
expressions on the scope) as well as updating the DOM (i.e., manipulation of iElement = individual instance element). It is executed after the template has been cloned. E.g., inside an <li ng-repeat...>
, the link function is executed after the <li>
template (tElement) has been cloned (into an iElement) for that particular <li>
element. A $watch
allows a directive to be notified of scope property changes (a scope is associated with each instance), which allows the directive to render an updated instance value to the DOM.
controller function - must be used when another directive needs to interact with this directive. E.g., on the AngularJS home page, the pane directive needs to add itself to the scope maintained by the tabs directive, hence the tabs directive needs to define a controller method (think API) that the pane directive can access/call.
For a more in-depth explanation of the tabs and pane directives, and why the tabs directive creates a function on its controller using this
(rather than on $scope
), please see 'this' vs $scope in AngularJS controllers.
In general, you can put methods, $watches
, etc. into either the directive's controller or link function. The controller will run first, which sometimes matters (see this fiddle which logs when the ctrl and link functions run with two nested directives). As Josh mentioned in a comment, you may want to put scope-manipulation functions inside a controller just for consistency with the rest of the framework.
A single liner, using find
:
find -type f -exec grep -lm1 "PATTERN" {} \; -a -quit
Have a look at the GROUP_CONCAT project on Github, I think I does exactly what you are searching for:
This project contains a set of SQLCLR User-defined Aggregate functions (SQLCLR UDAs) that collectively offer similar functionality to the MySQL GROUP_CONCAT function. There are multiple functions to ensure the best performance based on the functionality required...
If you're platform is Windows, I wouldn't actually recommend Python. Instead, look into Autohotkey. Trust me, I love Python, but in this circumstance a macro program is the ideal tool for the job. Autohotkey's scripting is only decent (in my opinion), but the ease of simulating input will save you countless hours. Autohotkey scripts can be "compiled" as well so you don't need the interpreter to run the script.
Also, if this is for something on the Web, I recommend iMacros. It's a firefox plugin and therefore has a much better integration with websites. For example, you can say "write 1000 'a's in this form" instead of "simulate a mouseclick at (319,400) and then press 'a' 1000 times".
For Linux, I unfortunately have not been able to find a good way to easily create keyboard/mouse macros.
You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:
#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);
You can also specify a code page, so if your std::string contains UTF-8 chars you can use:
CA2W pszWide(str.c_str(), CP_UTF8);
Very useful but Windows only.
Git will not store the password when you use URLs like that. Instead, it will just store the username, so it only needs to prompt you for the password the next time. As explained in the manual, to store the password, you should use an external credential helper. For Windows, you can use the Windows Credential Store for Git. This helper is also included by default in GitHub for Windows.
When using it, your password will automatically be remembered, so you only need to enter it once. So when you clone, you will be asked for your password, and then every further communication with the remote will not prompt you for your password again. Instead, the credential helper will provide Git with the authentication.
This of course only works for authentication via https; for ssh access ([email protected]/repository.git
) you use SSH keys and those you can remember using ssh-agent
(or PuTTY’s pageant if you’re using plink).
Can be solved using a simple directive "go-back-history", this one is also closing window in case of no previous history.
Directive usage
<a data-go-back-history>Previous State</a>
Angular directive declaration
.directive('goBackHistory', ['$window', function ($window) {
return {
restrict: 'A',
link: function (scope, elm, attrs) {
elm.on('click', function ($event) {
$event.stopPropagation();
if ($window.history.length) {
$window.history.back();
} else {
$window.close();
}
});
}
};
}])
Note: Working using ui-router or not.
the difference is not between <span>
and <div>
specifically, but between inline
and block
elements. <span>
defaults to being display:inline;
whereas <div>
defaults to being display:block;
. But these can be overridden in CSS.
The difference in the way text-align:center
works between the two is down to the width.
A block
element defaults to being the width of its container. It can have its width set using CSS, but either way it is a fixed width.
An inline
element takes its width from the size of its content text.
text-align:center
tells the text to position itself centrally in the element. But in an inline
element, this is clearly not going to have any effect because the element is the same width as the text; aligning it one way or the other is meaningless.
In a block
element, because the element's width is independent of the content, the content can be positioned within the element using the text-align
style.
Finally, a solution for you:
There is an additional value for the display
property which provides a half-way house between block
and inline
. Conveniently enough, it's called inline-block
. If you specify a <span>
to be display:inline-block;
in the CSS, it will continue to work as an inline element but will take on some of the properties of a block as well, such as the ability to specify a width
. Once you specify a width for it, you will be able to center the text within that width using text-align:center;
Hope that helps.
The empty string is false as a rule.
Apparently the empty string is not respected as empty in all browsers and the presence of the checked attribute is taken to mean checked. So the entire attribute must either be present or omitted.
As mentioned in my earlier answer, you can use RegExp.exec()
to iterate over all matches and count each occurrence; the advantage is limited to memory only, because on the whole it's about 20% slower than using String.match()
.
var re = /\s/g,
count = 0;
while (re.exec(text) !== null) {
++count;
}
return count;
To force download you may use Content-Type: application/force-download
header, which is supported by most browsers:
function downloadFile($filePath)
{
header("Content-type: application/octet-stream");
header('Content-Disposition: attachment; filename="' . basename($filePath) . '"');
header('Content-Length: ' . filesize($filePath));
readfile($filePath);
}
A BETTER WAY
Downloading files this way is not the best idea especially for large files. PHP will require extra CPU / Memory to read and output file contents and when dealing with large files may reach time / memory limits.
A better way would be to use PHP to authenticate and grant access to a file, and actual file serving should be delegated to a web server using X-SENDFILE method (requires some web server configuration):
X-SENDFILE
is natively supported by Lighttpd: https://redmine.lighttpd.net/projects/1/wiki/X-LIGHTTPD-send-filemod_xsendfile
module: https://tn123.org/mod_xsendfile/ On Ubuntu may be installed by: apt install libapache2-mod-xsendfile
X-Accel-Redirect
header: https://www.nginx.com/resources/wiki/start/topics/examples/xsendfile/After configuring web server to handle X-SENDFILE
, just replace readfile($filePath)
with header('X-SENDFILE: ' . $filePath)
and web server will take care of file serving, which will require less resources than using PHP readfile
.
(For Nginx use X-Accel-Redirect
header instead of X-SENDFILE
)
Note: If you end up downloading empty files, it means you didn't configure your web server to handle X-SENDFILE
header. Check the links above to see how to correctly configure your web server.

If you need access to the entire file system on the client, read/write files, watch folders for changes, start applications, encrypt or sign documents, etc. please have a look at JSFS.
It allows secure and unlimited access from your web page to computer resources on the client without using a browser plugin technology like AcitveX or Java Applet. However, a peace of software has to be installed too.
In order to work with JSFS you should have basic knowledge in Java and Java EE development (Servlets).

The value 1382086394000 is probably a time value, which is the number of milliseconds since 1970-01-01T00:00:00Z. You can use it to create an ECMAScript Date object using the Date constructor:
var d = new Date(1382086394000);
How you convert that into something readable is up to you. Simply sending it to output should call the internal (and entirely implementation dependent) toString method* that usually prints the equivalent system time in a human readable form, e.g.
Fri Oct 18 2013 18:53:14 GMT+1000 (EST)
In ES5 there are some other built-in formatting options:
and so on. Note that most are implementation dependent and will be different in different browsers. If you want the same format across all browsers, you'll need to format the date yourself, e.g.:
alert(d.getDate() + '/' + (d.getMonth()+1) + '/' + d.getFullYear());
* The format of Date.prototype.toString has been standardised in ECMAScript 2018. It might be a while before it's ubiquitous across all implementations, but at least the more common browsers support it now.
I had the same problem when trying to call re captcha button. After some searching, now the below function works fine in almost all the famous browsers(chrome,Firefox,IE,Edge,...):
function recaptcha(theUrl) {
$.get(theUrl, function(data, status){});
$("#captcha-img").attr('src', "");
setTimeout(function(){
$("#captcha-img").attr('src', "captcha?"+new Date().getTime());
}, 0);
}
'theUrl' is used to render new captcha image and can be ignored in your case. The most important point is generating new URL which forces FF and IE to rerender the image.
Isn't neither localStorage or httpOnly cookie acceptable? In regards to a compromised 3rd party library, the only solution I know of that will reduce / prevent sensitive information from being stolen would be enforced Subresource Integrity.
Subresource Integrity (SRI) is a security feature that enables browsers to verify that resources they fetch (for example, from a CDN) are delivered without unexpected manipulation. It works by allowing you to provide a cryptographic hash that a fetched resource must match.
As long as the compromised 3rd party library is active on your website, a keylogger can start collecting info like username, password, and whatever else you input into the site.
An httpOnly cookie will prevent access from another computer but will do nothing to prevent the hacker from manipulating the user's computer.
Here is the reproduced error.
>>> d = {}
>>> d.update([(1,)])
Traceback (most recent call last):

>>> d.update('hello_some_string')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: dictionary update sequence element #0 has length 1; 2 is required
>>>
If you give the sequence and any element length is 1 and required two then we will get this kind of error. See the above code. First time I gave the sequence with tuple and it's length 1, then we got the error and dictionary is not updated. second time I gave inside tuple with with two elements, dictionary got updated.

It takes a few steps to get the perfect preview for WhatsApp, Twitter, Facebook and bookmark icons for pc's and mobile devices. If you like reading go to ogp.me - but make sure to read steps 1 - 6 in this answer to get the best WhatsApp preview.
Please note: some apps or websites use cache or even store the website preview to their database. This means when you're testing your link in WhatsApp or Facebook for example, you'll most likely not see any difference right away. Using another link (another page) will do the trick. But as soon as you use that link once, this "please note" section starts all over again.
Step 1: title
Maximum of 65 characters
<title>your keyword rich title of the website and/or webpage</title>
Step 2: description
Maximum of 155 characters
<meta name="description" content="description of your website/webpage, make sure you use keywords!">
Step 3: og:title
Maximum 35 characters
<meta property="og:title" content="short title of your website/webpage" />
Step 4: og:url
Full link to the current webpage address
<meta property="og:url" content="https://www.example.com/webpage/" />
Step 5: og:description
Maximum 65 characters
<meta property="og:description" content="description of your website/webpage">
Step 6: og:image
Image(JPG or PNG) with a size less than 300KB and minimum dimensions of 300 x 200 *. This image should be served via a HTTPS connection with a valid non-self-signed certificate.
<meta property="og:image" content="//cdn.example.com/uploads/images/webpage_300x200.png">
* @RichDeBourke mentioned this to me, but apparently WhatsApp has increased its maximum image size (dimensions as well as file size). I did some tests: it does not work consistently every time on every device. I tested 2.x Mb images and even that seemed to work 9/10 times. <300KB is the safest approach, but you should be fine using larger images as of 18-02-2020. I would recommend keeping the file size below 2MB, though. And definitely throw your image through TinyPNG or any other image compression algorithm if you haven't already.
If you completed the steps above, you can now see your preview in WhatsApp! However, be aware of the "please note" section above.
Step 7: og:type
In order for your object to be represented within the graph, you need to specify its type. Here's a list of the global types available: http://ogp.me/#types. You can also specify your own types.
<meta property="og:type" content="article" />
Step 8: og:locale
The locale of the resource. You can also use og:locale:alternate if you have other language translations available.
If you don't specify og:locale, it defaults to en_US.
<meta property="og:locale" content="en_GB" />
<meta property="og:locale:alternate" content="fr_FR" />
<meta property="og:locale:alternate" content="es_ES" />
Step 9: Twitter
For the best Twitter support read this.
Step 10: Facebook
For the best Facebook support read this.
Step 11: favicon
For the best favicon support for all browsers and devices read this.
Bonus step 12: video/audio
It's also possible to share audio/video. Facebook and twitter for example share videos very well. Read ogp.me.

You get this behavior, because int array [ROW][COLUMN] = {1};
does not mean "set all items to one". Let me try to explain how this works step by step.
The explicit, overly clear way of initializing your array would be like this:
#define ROW 2
#define COLUMN 2
int array [ROW][COLUMN] =
{
{0, 0},
{0, 0}
};
However, C allows you to leave out some of the items in an array (or struct/union). You could for example write:
int array [ROW][COLUMN] =
{
{1, 2}
};
This means, initialize the first elements to 1 and 2, and the rest of the elements "as if they had static storage duration". There is a rule in C saying that all objects of static storage duration, that are not explicitly initialized by the programmer, must be set to zero.
So in the above example, the first row gets set to 1,2 and the next to 0,0 since we didn't give them any explicit values.
Next, there is a rule in C allowing lax brace style. The first example could as well be written as
int array [ROW][COLUMN] = {0, 0, 0, 0};
although of course this is poor style, it is harder to read and understand. But this rule is convenient, because it allows us to write
int array [ROW][COLUMN] = {0};
which means: "initialize the very first column in the first row to 0, and all other items as if they had static storage duration, ie set them to zero."
therefore, if you attempt
int array [ROW][COLUMN] = {1};
it means "initialize the very first column in the first row to 1 and set all other items to zero".
Just several days ago, I met the same question just like yours. All code runs well on my local machine, but turns out error(noclassdeffound&initialize). So I post my solution, but I don't know why, I merely advance a possibility. I hope someone know will explain this.@John Vint Firstly, I'll show you my problem. My code has static variable and static block both. When I first met this problem, I tried John Vint's solution, and tried to catch the exception. However, I caught nothing. So I thought it is because the static variable(but now I know they are the same thing) and still found nothing. So, I try to find the difference between the linux machine and my computer. Then I found that this problem happens only when several threads run in one process(By the way, the linux machine has double cores and double processes). That means if there are two tasks(both uses the code which has static block or variables) run in the same process, it goes wrong, but if they run in different processes, both of them are ok. In the Linux machine, I use
mvn -U clean test -Dtest=path
to run a task, and because my static variable is to start a container(or maybe you initialize a new classloader), so it will stay until the jvm stop, and the jvm stops only when all the tasks in one process stop. Every task will start a new container(or classloader) and it makes the jvm confused. As a result, the error happens. So, how to solve it? My solution is to add a new command to the maven command, and make every task go to the same container.
-Dxxx.version=xxxxx #sorry can't post more
Maybe you have already solved this problem, but still hope it will help others who meet the same problem.
To really fine-tune things, I recommend placing the appropriate selections in browser-targeting wrappers. This was the only thing that worked for me when I could not get IE7 and IE8 to "play nicely with others" (as I am currently working for a software company who continues to support them).
/* color or background image for all browsers, of course */
#myBackground {
background-color:#666;
}
/* target chrome & safari without disrupting IE7-8 */
@media screen and (-webkit-min-device-pixel-ratio:0) {
#myBackground {
-khtml-opacity:.50;
opacity:.50;
}
}
/* target firefox without disrupting IE */
@-moz-document url-prefix() {
#myBackground {
-moz-opacity:.50;
opacity:0.5;
}
}
/* and IE last so it doesn't blow up */
#myBackground {
opacity:.50;
filter:alpha(opacity=50);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
}
I may have redundancies in the above code -- if anyone wishes to clean it up further, feel free!
Mat image1;
IplImage* image2=cvCloneImage(&(IplImage)image1);
Guess this will do the job.
Edit: If you face compilation errors, try this way:
cv::Mat image1;
IplImage* image2;
image2 = cvCreateImage(cvSize(image1.cols,image1.rows),8,3);
IplImage ipltemp=image1;
cvCopy(&ipltemp,image2);
I seemed to solve this by manually removing the unicorn gem via bundler ("sudo bundler exec gem uninstall unicorn"), then rebundling ("sudo bundle install").
Not sure why it happened though, although the above fix does seem to work.
you can add an edit text of size "0 dip" as the first control in ur xml, so, that will get the focus on render.(make sure its focusable and all...)
To show result till yesterday
WHERE DATE(date_time) < CURDATE()
To show results of 10 days
WHERE date_time < NOW() - INTERVAL 10 DAY
To show results before 10 days
WHERE DATE(date_time) < DATE(NOW() - INTERVAL 10 DAY)
These will work for you
You can find dates like this

This happened to me and it took me an hour to find it. In my case I had typed too fast and did:
[seld method];
instead of:
[self method];
Seriously! I don't know why it didn't catch this in a more recognizable way. But it was of course looking for a class called "seld".
See the notes at http://www.php.net/manual/en/function.ereg.php:
Note:
As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED notice. See the list of differences for help on converting to PCRE.
Note:
preg_match(), which uses a Perl-compatible regular expression syntax, is often a faster alternative to ereg().
I found that when I created a scene via the three.js editor, I not only had to use the correct answer's code (above), to set up the renderer with an alpha value and the clear color, I had to go into the app.json file and find the "Scene" Object's "background" attribute and set it to:
"background: null"
.
The export from Three.js editor had it originally set to "background": 0
jus add two zeroes (00) before your color code you will get the transparent of that color
std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();
This is a great place for auto
:
auto now = std::chrono::system_clock::now();
Since you want to traffic at millisecond
precision, it would be good to go ahead and covert to it in the time_point
:
auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);
now_ms
is a time_point
, based on system_clock
, but with the precision of milliseconds
instead of whatever precision your system_clock
has.
auto epoch = now_ms.time_since_epoch();
epoch
now has type std::chrono::milliseconds
. And this next statement becomes essentially a no-op (simply makes a copy and does not make a conversion):
auto value = std::chrono::duration_cast<std::chrono::milliseconds>(epoch);
Here:
long duration = value.count();
In both your and my code, duration
holds the number of milliseconds
since the epoch of system_clock
.
This:
std::chrono::duration<long> dur(duration);
Creates a duration
represented with a long
, and a precision of seconds
. This effectively reinterpret_cast
s the milliseconds
held in value
to seconds
. It is a logic error. The correct code would look like:
std::chrono::milliseconds dur(duration);
This line:
std::chrono::time_point<std::chrono::system_clock> dt(dur);
creates a time_point
based on system_clock
, with the capability of holding a precision to the system_clock
's native precision (typically finer than milliseconds). However the run-time value will correctly reflect that an integral number of milliseconds are held (assuming my correction on the type of dur
).
Even with the correction, this test will (nearly always) fail though:
if (dt != now)
Because dt
holds an integral number of milliseconds
, but now
holds an integral number of ticks finer than a millisecond
(e.g. microseconds
or nanoseconds
). Thus only on the rare chance that system_clock::now()
returned an integral number of milliseconds
would the test pass.
But you can instead:
if (dt != now_ms)
And you will now get your expected result reliably.
Putting it all together:
int main ()
{
auto now = std::chrono::system_clock::now();
auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);
auto value = now_ms.time_since_epoch();
long duration = value.count();
std::chrono::milliseconds dur(duration);
std::chrono::time_point<std::chrono::system_clock> dt(dur);
if (dt != now_ms)
std::cout << "Failure." << std::endl;
else
std::cout << "Success." << std::endl;
}
Personally I find all the std::chrono
overly verbose and so I would code it as:
int main ()
{
using namespace std::chrono;
auto now = system_clock::now();
auto now_ms = time_point_cast<milliseconds>(now);
auto value = now_ms.time_since_epoch();
long duration = value.count();
milliseconds dur(duration);
time_point<system_clock> dt(dur);
if (dt != now_ms)
std::cout << "Failure." << std::endl;
else
std::cout << "Success." << std::endl;
}
Which will reliably output:
Success.
Finally, I recommend eliminating temporaries to reduce the code converting between time_point
and integral type to a minimum. These conversions are dangerous, and so the less code you write manipulating the bare integral type the better:
int main ()
{
using namespace std::chrono;
// Get current time with precision of milliseconds
auto now = time_point_cast<milliseconds>(system_clock::now());
// sys_milliseconds is type time_point<system_clock, milliseconds>
using sys_milliseconds = decltype(now);
// Convert time_point to signed integral type
auto integral_duration = now.time_since_epoch().count();
// Convert signed integral type to time_point
sys_milliseconds dt{milliseconds{integral_duration}};
// test
if (dt != now)
std::cout << "Failure." << std::endl;
else
std::cout << "Success." << std::endl;
}
The main danger above is not interpreting integral_duration
as milliseconds
on the way back to a time_point
. One possible way to mitigate that risk is to write:
sys_milliseconds dt{sys_milliseconds::duration{integral_duration}};
This reduces risk down to just making sure you use sys_milliseconds
on the way out, and in the two places on the way back in.
And one more example: Let's say you want to convert to and from an integral which represents whatever duration system_clock
supports (microseconds, 10th of microseconds or nanoseconds). Then you don't have to worry about specifying milliseconds as above. The code simplifies to:
int main ()
{
using namespace std::chrono;
// Get current time with native precision
auto now = system_clock::now();
// Convert time_point to signed integral type
auto integral_duration = now.time_since_epoch().count();
// Convert signed integral type to time_point
system_clock::time_point dt{system_clock::duration{integral_duration}};
// test
if (dt != now)
std::cout << "Failure." << std::endl;
else
std::cout << "Success." << std::endl;
}
This works, but if you run half the conversion (out to integral) on one platform and the other half (in from integral) on another platform, you run the risk that system_clock::duration
will have different precisions for the two conversions.
From the Flask API Documentation (v. 0.10):
flask.redirect(
location
,code=302
,Response=None
)Returns a response object (a WSGI application) that, if called, redirects the client to the target location. Supported codes are 301, 302, 303, 305, and 307. 300 is not supported because it’s not a real redirect and 304 because it’s the answer for a request with a request with defined If-Modified-Since headers.
New in version 0.6: The location can now be a unicode string that is encoded using the iri_to_uri() function.
Parameters:
location
– the location the response should redirect to.code
– the redirect status code. defaults to 302.Response
(class) – a Response class to use when instantiating a response. The default is werkzeug.wrappers.Response if unspecified.
Try pasting this to .htaccess and it should work.

A few years late, but I have a solution for the most recent version of WordPress, which has this same issue (WordPress-generated .htaccess files break sites, reuslting in 403 Forbidden error messages). Here's that it looks like when WordPress creates it:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
The problem is that the conditional doesn't work. It doesn't work because the module it's looking for isn't .c
, it's .so
. I think this is a platform-specific, or configuration-specific issue, where Mac OS and Lunix Apache installations are set up for .so
AKA 'shared-object' modules. Looking for a .c
module shouldn't break the conditional, I think that's a bug, but it's the issue.
Simply change the mod_rewrite.c
to mod_rewrite.so
and you're all set to go!
# BEGIN WordPress
<IfModule mod_rewrite.so>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Your variable size
is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
You could cast it to convert to an integer:
float *temp = new float[(int)size];
Your other problem is likely because you're writing outside of the bounds of the array:
float *temp = new float[size];
//Getting input from the user
for (int x = 1; x <= size; x++){
cout << "Enter temperature " << x << ": ";
// cin >> temp[x];
// This should be:
cin >> temp[x - 1];
}
Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.
I have used Meld once, which seemed very nice, and I may try more often. vimdiff works well, if you know vim well. Lastly I would mention I've found xxdiff does a reasonable job for a quick comparison. There are many diff programs out there which do a good job.
If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/
It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates
Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/
There are some SPARQL libraries available for multiple platforms to make queries easier

You won't be able to make an ajax call to http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml
from a file deployed at http://run.jsbin.com
due to the same-origin policy.
As the source (aka origin) page and the target URL are at different domains (run.jsbin.com
and www.ecb.europa.eu
), your code is actually attempting to make a Cross-domain (CORS) request, not an ordinary GET
.
In a few words, the same-origin policy says that browsers should only allow ajax calls to services at the same domain of the HTML page.
A page at http://www.example.com/myPage.html
can only directly request services that are at http://www.example.com
, like http://www.example.com/api/myService
. If the service is hosted at another domain (say http://www.ok.com/api/myService
), the browser won't make the call directly (as you'd expect). Instead, it will try to make a CORS request.
To put it shortly, to perform a (CORS) request* across different domains, your browser:
Origin
header in the original request (with the page's domain as value) and perform it as usual; and thenAccess-Control-Allow-Origin
is one of them) allowing the CORS request, the browse will complete the call (almost** exactly the way it would if the HTML page was at the same domain).
* The above depicts the steps in a simple request, such as a regular GET
with no fancy headers. If the request is not simple (like a POST
with application/json
as content type), the browser will hold it a moment, and, before fulfilling it, will first send an OPTIONS
request to the target URL. Like above, it only will continue if the response to this OPTIONS
request contains the CORS headers. This OPTIONS
call is known as preflight request.
** I'm saying almost because there are other differences between regular calls and CORS calls. An important one is that some headers, even if present in the response, will not be picked up by the browser if they aren't included in the Access-Control-Expose-Headers
header.
Was it just a typo? Sometimes the JavaScript code has just a typo in the target domain. Have you checked? If the page is at www.example.com
it will only make regular calls to www.example.com
! Other URLs, such as api.example.com
or even example.com
or www.example.com:8080
are considered different domains by the browser! Yes, if the port is different, then it is a different domain!
Add the headers. The simplest way to enable CORS is by adding the necessary headers (as Access-Control-Allow-Origin
) to the server's responses. (Each server/language has a way to do that - check some solutions here.)
Last resort: If you don't have server-side access to the service, you can also mirror it (through tools such as reverse proxies), and include all the necessary headers there.
From the fine manual:
ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;
There's no need to specify the type when you're just changing the nullability.
Is your BitLocker disk encryption running? In my case, it locked the whole drive of the disk for encryption, and SVN failed with this error.
Two very different types of Pipes Angular - Pipes and RxJS - Pipes
A pipe takes in data as input and transforms it to a desired output. In this page, you'll use pipes to transform a component's birthday property into a human-friendly date.
import { Component } from '@angular/core';
@Component({
selector: 'app-hero-birthday',
template: `<p>The hero's birthday is {{ birthday | date }}</p>`
})
export class HeroBirthdayComponent {
birthday = new Date(1988, 3, 15); // April 15, 1988
}
Observable operators are composed using a pipe method known as Pipeable Operators. Here is an example.
import {Observable, range} from 'rxjs';
import {map, filter} from 'rxjs/operators';
const source$: Observable<number> = range(0, 10);
source$.pipe(
map(x => x * 2),
filter(x => x % 3 === 0)
).subscribe(x => console.log(x));
The output for this in the console would be the following:
0
6
12
18
For any variable holding an observable, we can use the .pipe() method to pass in one or multiple operator functions that can work on and transform each item in the observable collection.
So this example takes each number in the range of 0 to 10, and multiplies it by 2. Then, the filter function to filter the result down to only the odd numbers.

I found that the best way it to add always the +trace option:
dig SOA +trace stackoverflow.com
It works also with recursive CNAME hosted in different provider. +trace trace imply +norecurse so the result is just for the domain you specify.
You need an external library for this.
JSONArray jsonA = JSONArray.fromObject(mybeanList);
System.out.println(jsonA);
Google GSON is one of such libraries
You can also take a look here for examples on converting Java object collection to JSON string.

-Xmn : the size of the heap for the young generation
Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor".
And a more "official" source from IBM:
-Xmn
Sets the initial and maximum size of the new (nursery) heap to the specified value when using -Xgcpolicy:gencon. Equivalent to setting both -Xmns and -Xmnx. If you set either -Xmns or -Xmnx, you cannot set -Xmn. If you attempt to set -Xmn with either -Xmns or -Xmnx, the VM will not start, returning an error. By default, -Xmn is selected internally according to your system's capability. You can use the -verbose:sizes option to find out the values that the VM is currently using.
VS (2013 Pro, Win 8.1) restart did it for me.
If you're only working with the single digits 0-9, it's likely faster to build a lookup table so you don't have to call the conversion functions every time.
lookup_table = Hash.new
(0..9).each {|x|
lookup_table[x] = x.to_s(2)
lookup_table[x.to_s] = x.to_s(2)
}
lookup_table[5]
=> "101"
lookup_table["8"]
=> "1000"
Indexing into this hash table using either the integer or string representation of a number will yield its binary representation as a string.
If you require the binary strings to be a certain number of digits long (keep leading zeroes), then change x.to_s(2)
to sprintf "%04b", x
(where 4
is the minimum number of digits to use).
If you want to use @Html.EditorFor() you have to use jQuery ui and update your Asp.net Mvc to 5.2.6.0 with NuGet Package Manager.
@Html.EditorFor(m => m.EntryDate, new { htmlAttributes = new { @class = "datepicker" } })
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
<script>
$(document).ready(function(){
$('.datepicker').datepicker();
});
</script>
}
select CONVERT((column_name) USING utf8) FROM table;
In my case, Workbench does not work. so i used the above solution to show blob data as text.
Try using *
unpack, like below:
>>> a=set('abcde')
>>> a
{'a', 'd', 'e', 'b', 'c'}
>>> l=['f','g']
>>> l
['f', 'g']
>>> {*l, *a}
{'a', 'd', 'e', 'f', 'b', 'g', 'c'}
>>>
Non Editor version:
a=set('abcde')
l=['f', 'g']
print({*l, *a})
Output:
{'a', 'd', 'e', 'f', 'b', 'g', 'c'}
Everybody seems to refer to date being a column in the table.
I dont think this is good practice. The word date might just be a keyword in some coding language (maybe Oracle) so please change the columnname date to maybe JDate.
So will the following work better:
SELECT * FROM jokes WHERE JDate >= CURRENT_DATE() ORDER BY JScore DESC;
So we have a table called Jokes with columns JScore and JDate.

Which one of their Grids are you using? XtraGrid or AspXGrid? Here is a piece taken from one of my app using XtraGrid.
private void grdContactsView_RowClick(object sender, DevExpress.XtraGrid.Views.Grid.RowClickEventArgs e)
{
_selectedContact = GetSelectedRow((DevExpress.XtraGrid.Views.Grid.GridView)sender);
}
private Contact GetSelectedRow(DevExpress.XtraGrid.Views.Grid.GridView view)
{
return (Contact)view.GetRow(view.FocusedRowHandle);
}
My Grid have a list of Contact objects bound to it. Every time a row is clicked I load the selected row into _selectedContact. Hope this helps. You will find lots of information on using their controls buy visiting their support and documentation sites.
Here are the steps to follow.
You do not have to set the preferred size of the JLabel. Once you've scaled the image to the size you want, the JLabel will take the size of the ImageIcon.
BufferedImage img = null;
try {
img = ImageIO.read(new File("strawberry.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
Image dimg = img.getScaledInstance(label.getWidth(), label.getHeight(),
Image.SCALE_SMOOTH);
Make sure that the label width and height are the same proportions as the original image width and height. In other words, if the picture is 600 x 900 pixels, scale to 100 X 150. Otherwise, your picture will be distorted.
ImageIcon imageIcon = new ImageIcon(dimg);
If you have url like https://myapp.com/owner/123/show?height=23 then use
combineLatest( [this.route.paramMap, this.route.queryParamMap] )
.subscribe( ([pathParams, queryParams]) => {
let ownerId = pathParams.get('ownerId'); // =123
let height = queryParams.get('height'); // =height
// ...
})
In case when you use this.router.navigate([yourUrl]);
and your query parameters are embedded in yourUrl
string then angular encodes a URL and you get something like this https://myapp.com/owner/123/show%3Fheight%323 - and above solution will give wrong result (queryParams will be empty, and query params can be glued to last path param if it is on the path end). In this case change the way of navigation to this
this.router.navigateByUrl(yourUrl);

@Ryan Cavanaugh's answer is totally ok and still valid. Still it worth to add that as of Fall'16 when we can claim that ES6 is supported by the majority of platforms it almost always better to stick to Map whenever you need associate some data with some key.
When we write let a: { [s: string]: string; }
we need to remember that after typescript compiled there's not such thing like type data, it's only used for compiling. And { [s: string]: string; } will compile to just {}.
That said, even if you'll write something like:
class TrickyKey {}
let dict: {[key:TrickyKey]: string} = {}
This just won't compile (even for target es6
, you'll get error TS1023: An index signature parameter type must be 'string' or 'number'.
So practically you are limited with string or number as potential key so there's not that much of a sense of enforcing type check here, especially keeping in mind that when js tries to access key by number it converts it to string.
So it is quite safe to assume that best practice is to use Map even if keys are string, so I'd stick with:
let staff: Map<string, string> = new Map();
You can make a JavaScript function to do that:
$.clearInput = function () {
$('form').find('input[type=text], input[type=password], input[type=number], input[type=email], textarea').val('');
};
and then you can call that function each time your modal is hidden:
$('#Your_Modal').on('hidden', function () {
$.clearInput();
});
This is exactly how it worked for me. For some reason the above code failed.

As someone who is also learning pandas I found the other answers a bit implicit as pandas hides most of the work behind the scenes. Namely in how the operation works by automatically matching up column and index names. This code should be equivalent to a step by step version of @exp1orer's accepted answer
With the df
, I'll call it by the alias state_office_sales
:

state_total_sales
is state_office_sales
grouped by total sums in index level 0
(leftmost).
In: state_total_sales = df.groupby(level=0).sum()
state_total_sales
Out:
sales
state
AZ 2448009
CA 2832270
CO 1495486
WA 595859
Because the two dataframes share an index-name and a column-name pandas will find the appropriate locations through shared indexes like:
In: state_office_sales / state_total_sales
Out:
sales
state office_id
AZ 2 0.448640

6 0.331986
To illustrate this even better, here is a partial total with a XX
that has no equivalent. Pandas will match the location based on index and column names, where there is no overlap pandas will ignore it:
In: partial_total = pd.DataFrame(
data = {'sales' : [2448009, 595859, 99999]},

)

This does not work:
string s = (string)malloc(sizeof string);
string
refers to a pointer, you need the size of the structure itself:
string s = malloc(sizeof (*string));
Note the lack of cast as well (conversion from void*
(malloc
's return type) is implicitly performed).
Also, in your main
, you have a globally delcared patient
, but that is uninitialized. Try:
patient.number = 3;
patient.name = "John";
patient.address = "Baker street";
patient.birthdate = "4/15/2012";
patient.gender = 'M';
before you read-access any of its members
Also, strcpy
is inherently unsafe as it does not have boundary checking (will copy until the first '\0'
is encountered, writing past allocated memory if the source is too long). Use strncpy
instead, where you can at least specify the maximum number of characters copied -- read the documentation to ensure you pass the correct value, it is easy to make an off-by-one error.
I was just looking for this... By using David's answer, I used a span and gave it some padding (height won't work + top margin issue)... Works like a charm;

in fork(), either child or parent process will execute based on cpu selection.. But in vfork(), surely child will execute first. after child terminated, parent will execute.

The reduce function also works
import operator
h=['a','b','c','d']
reduce(operator.add, h)
'abcd'
You can also set the title of your chart by adding the title parameter as follows
ax.set(xlabel='common xlabel', ylabel='common ylabel', title='some title')
A few other good references on those topics:
I use the index as a checkpoint.
When I'm about to make a change that might go awry — when I want to explore some direction that I'm not sure if I can follow through on or even whether it's a good idea, such as a conceptually demanding refactoring or changing a representation type — I checkpoint my work into the index.
If this is the first change I've made since my last commit, then I can use the local repository as a checkpoint, but often I've got one conceptual change that I'm implementing as a set of little steps.
I want to checkpoint after each step, but save the commit until I've gotten back to working, tested code.
Notes:
the workspace is the directory tree of (source) files that you see and edit.
The index is a single, large, binary file in
<baseOfRepo>/.git/index
, which lists all files in the current branch, their sha1 checksums, time stamps and the file name -- it is not another directory with a copy of files in it.The local repository is a hidden directory (
.git
) including anobjects
directory containing all versions of every file in the repo (local branches and copies of remote branches) as a compressed "blob" file.Don't think of the four 'disks' represented in the image above as separate copies of the repo files.
They are basically named references for Git commits. There are two major types of refs: tags and heads.
- Tags are fixed references that mark a specific point in history, for example v2.6.29.
- On the contrary, heads are always moved to reflect the current position of project development.
(note: as commented by Timo Huovinen, those arrows are not what the commits point to, it's the workflow order, basically showing arrows as 1 -> 2 -> 3 -> 4
where 1
is the first commit and 4
is the last)
Now we know what is happening in the project.
But to know what is happening right here, right now there is a special reference called HEAD. It serves two major purposes:
- it tells Git which commit to take files from when you checkout, and
- it tells Git where to put new commits when you commit.
When you run
git checkout ref
it pointsHEAD
to the ref you’ve designated and extracts files from it. When you rungit commit
it creates a new commit object, which becomes a child of currentHEAD
. NormallyHEAD
points to one of the heads, so everything works out just fine.
You can use a2enmod
or a2dismod
to enable/disable modules by name.
From terminal, run: sudo a2enmod php5
to enable PHP5 (or some other module), then sudo service apache2 reload
to reload the Apache2 configuration.
you can use this:
^\d+(\.\d)?\d*$
matches:
11
11.1
0.2
does not match:
.2
2.
2.6.9
Use copy()
instead, which is willing to overwrite destination files. If you then want the first tree to go away, just rmtree()
it separately once you are done iterating over it.
http://docs.python.org/library/shutil.html#shutil.copy
http://docs.python.org/library/shutil.html#shutil.rmtree
Update:
Do an os.walk()
over the source tree. For each directory, check if it exists on the destination side, and os.makedirs()
it if it is missing. For each file, simply shutil.copy()
and the file will be created or overwritten, whichever is appropriate.
If you're using AMD modules, the other answers won't work in TypeScript 1.0 (the newest at the time of writing.)
You have different approaches available to you, depending upon how many things you wish to export from each .ts
file.
Foo.ts
export class Foo {}
export interface IFoo {}
Bar.ts
import fooModule = require("Foo");
var foo1 = new fooModule.Foo();
var foo2: fooModule.IFoo = {};
Foo.ts
class Foo
{}
export = Foo;
Bar.ts
import Foo = require("Foo");
var foo = new Foo();
in some cases where pywin32 is not the direct reference and other libraries require pywin32-ctypes to be installed; causes the "ImportError: No module named win32com" when application bundled with pyinstaller.
running following command solves on python 3.7 - pyinstaller 3.6
pip install pywin32==227
Take care with some of the examples; $0 may include some leading path as well as the name of the program. Eg save this two line script as ./mytry.sh and the execute it.
#!/bin/bash
echo "parameter 0 --> $0" ; exit 0
Output:
parameter 0 --> ./mytry.sh

Try putting this HTML snippet into your served document:
<img id="ItemPreview" src="">
Then, on JavaScript side, you can dynamically modify image's src
attribute with so-called Data URL.
document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;
Alternatively, using jQuery:
$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);
This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..."
part) in the URL accordingly.

You don't need a library beyond the standard one - just use Charset. (You can just use the String constructors and getBytes methods, but personally I don't like just working with the names of character encodings. Too much room for typos.)
EDIT: As pointed out in comments, you can still use Charset instances but have the ease of use of the String methods: new String(bytes, charset) and String.getBytes(charset).
See "URL Encoding (or: 'What are those "%20
" codes in URLs?')".
Collection is the Super interface of List so every Java list is as well an instance of collection. Collections are only iterable sequentially (and in no particular order) whereas a List allows access to an element at a certain position via the get(int index)
method.
There is a much easier way to compile and run C code using GCC, no configuration needed:
Ctrl+Alt+N
, or press F1
and then select/type Run Code
, or right click the Text Editor and then click Run Code
in context menu, the code will be compiled and run, and the output will be shown in the Output Window.Moreover you could update the config in settings.json using different C compilers as you want, the default config for C is as below:
"code-runner.executorMap": {
"c": "gcc $fullFileName && ./a.out"
}
You can try this also
SELECT id , IF(type='p', IFNULL(amount,0), IFNULL(amount,0) * -1) as amount FROM table

"equals" compare objects and return true or false and "compare to" return 0 if is true or an number [> 0] or [< 0] if is false here an example:

Integer num2 = 1;
//equal
System.out.println(num1.equals(num2));
System.out.println(num1.compareTo(num2));
//New Value
num2 = 3;//set value
//diferent
System.out.println(num1.equals(num2));
System.out.println(num1.compareTo(num2));
Results:
num1.equals(num2) =true
num1.compareTo(num2) =0
num1.equals(num2) =false
num1.compareTo(num2) =-1

Excerpt from the Java API for addAll(collection c) in Interface List see here

You you will have as much object as you have in both lists - the number of objects in your first list plus the number of objects you have in your second list - in your case 100.
Update the master branch, which you need to do regardless.
Then, one of:
Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.
Merge your branch into master, and resolve the merge conflicts.
Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.
None of these is better than the other, they just have different trade-off patterns.
I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.
To rebase and keep the branch you would:
git checkout <branch> && git rebase <target>
In your case, check out the old branch, then
git rebase master
to get it rebuilt against master.
Take a look at the Event Log API. Case a) (bluescreen, user cut the power cord or system hang) causes a note ('system did not shutdown correctly' or something like that) to be left in the 'System' event log the next time the system is rebooted properly. You should be able to access it programmatically using the above API (honestly, I've never used it but it should work).
this code worked for me:
window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId');
You could try this:
$scope.testdata = [{ 'name': 'name,id' }, {'name':'someName,someId'}]
$scope.array= [];
angular.forEach($scope.testdata, function (value, key) {
$scope.array.push({ 'name': value.name.split(',')[0], 'id': value.name.split(',')[1] });
});
console.log($scope.array)
This way you can save the data for later use and acces it by using an ng-repeat like this:
<div ng-repeat="item in array">{{item.name}}{{item.id}}</div>

I have created a higher-order function that has time complexity is o(n). Also, capability like the map to return any type you want.
extension Sequence {
func distinct<T,U>(_ provider: (Element) -> (U, T)) -> [T] where U: Hashable {
var uniqueKeys = Set<U>()
var distintValues = [T]()
for object in self {

if !uniqueKeys.contains(transformed.0) {
distintValues.append(transformed.1)
uniqueKeys.insert(transformed.0)

}
return distintValues

You can use zfill:
print str(1).zfill(2)
print str(10).zfill(2)
print str(100).zfill(2)
prints:
01
10
100
I like this solution, as it helps not only when outputting the number, but when you need to assign it to a variable... e.g. - x = str(datetime.date.today().month).zfill(2) will return x as '02' for the month of feb.

There's an easy, old-fashioned way to store user credentials in an HTTPS URL:
https://user:[email protected]/...
You can change the URL with git remote set-url <remote-repo> <URL>
The obvious downside to that approach is that you have to store the password in plain text. You can still just enter the user name (https://[email protected]/...
) which will at least save you half the hassle.
You might prefer to switch to SSH or to use the GitHub client software.
You can also use day names like Mon
for Monday, Tue
for Tuesday, etc. It's more human friendly.
As noted in the answer provided by Tim Cooper, java.awt.Desktop
has provided this capability since Java version 6 (1.6), but with the following caveat:
For platforms which do not support or provide java.awt.Desktop
, look into the BrowserLauncher2 project. It is derived and somewhat updated from the BrowserLauncher class originally written and released by Eric Albert. I used the original BrowserLauncher class successfully in a multi-platform Java application which ran locally with a web browser interface in the early 2000s.
Note that BrowserLauncher2 is licensed under the GNU Lesser General Public License. If that license is unacceptable, look for a copy of the original BrowserLauncher which has a very liberal license:

I wrote this code before a final attempt with Google and finding this page, so I thought I'd share it. It is basically an optimized version of Kisielewicz answer. I looked into the Barycentric method also but judging from the Wikipedia article I have a hard time seeing how it is more efficient (I'm guessing there is some deeper equivalence). Anyway, this algorithm has the advantage of not using division; a potential problem is the behavior of the edge detection depending on orientation.
bool intpoint_inside_trigon(intPoint s, intPoint a, intPoint b, intPoint c)
{
int as_x = s.x-a.x;
int as_y = s.y-a.y;
bool s_ab = (b.x-a.x)*as_y-(b.y-a.y)*as_x > 0;
if((c.x-a.x)*as_y-(c.y-a.y)*as_x > 0 == s_ab) return false;
if((c.x-b.x)*(s.y-b.y)-(c.y-b.y)*(s.x-b.x) > 0 != s_ab) return false;
return true;
}
In words, the idea is this: Is the point s to the left of or to the right of both the lines AB and AC? If true, it can't be inside. If false, it is at least inside the "cones" that satisfy the condition. Now since we know that a point inside a trigon (triangle) must be to the same side of AB as BC (and also CA), we check if they differ. If they do, s can't possibly be inside, otherwise s must be inside.
Some keywords in the calculations are line half-planes and the determinant (2x2 cross product). Perhaps a more pedagogical way is probably to think of it as a point being inside iff it's to the same side (left or right) to each of the lines AB, BC and CA. The above way seemed a better fit for some optimization however.
Enabeling GZip in Tomcat doesn't worked in my Spring Boot Project. I used CompressingFilter found here.
@Bean
public Filter compressingFilter() {
CompressingFilter compressingFilter = new CompressingFilter();
return compressingFilter;
}
I'd be cautious as dismissing something as a bad idea because it is slow. If it is a part of the code that does not take much time to execute then the slowness is irrelevant. I just used the following code:
for (ic in 1:(dim(centroid)[2]))
{
cluster[[ic]]=matrix(,nrow=2,ncol=0)
}
# code to identify cluster=pindex[ip] to which to add the point
if(pdist[ip]>-1)
{
cluster[[pindex[ip]]]=cbind(cluster[[pindex[ip]]],points[,ip])
}
for a problem that ran in less than 1 second.

You can have multiple ones, but it's not always the neatest thing to do. Try not to overuse them, as it will seriously affect readability. Other than that , it's perfectly legal. See the below:
http://www.learningjquery.com/2006/09/multiple-document-ready
Try this out:
$(document).ready(function() {
alert('Hello Tom!');
});
$(document).ready(function() {
alert('Hello Jeff!');
});
$(document).ready(function() {
alert('Hello Dexter!');
});
You'll find that it's equivalent to this, note the order of execution:
$(document).ready(function() {
alert('Hello Tom!');
alert('Hello Jeff!');
alert('Hello Dexter!');
});
It's also worth noting that a function defined within one $(document).ready
block cannot be called from another $(document).ready
block, I just ran this test:
$(document).ready(function() {
alert('hello1');
function saySomething() {
alert('something');
}
saySomething();
});
$(document).ready(function() {
alert('hello2');
saySomething();
});
output was:
hello1
something
hello2

How to visualize scalar 2D data with Matplotlib?
and
http://mri.brechmos.org/2009/07/automatically-update-a-figure-in-a-loop (on web.archive.org)
then modified them to use imshow with an input stack of frames, instead of generating and using contours on the fly.
Starting with a 3D array of images of shape (nBins, nBins, nBins), called frames
.
def animate_frames(frames):
nBins = frames.shape[0]
frame = frames[0]
tempCS1 = plt.imshow(frame, cmap=plt.cm.gray)
for k in range(nBins):
frame = frames[k]
tempCS1 = plt.imshow(frame, cmap=plt.cm.gray)

fig.clf()
fig = plt.figure()
ax = fig.add_subplot(111)
win = fig.canvas.manager.window
fig.canvas.manager.window.after(100, animate_frames, frames)
I also found a much simpler way to go about this whole process, albeit less robust:
fig = plt.figure()
for k in range(nBins):
plt.clf()
plt.imshow(frames[k],cmap=plt.cm.gray)
fig.canvas.draw()
time.sleep(1e-6) #unnecessary, but useful
Note that both of these only seem to work with ipython --pylab=tk

My approach to solving this problem is to use ES6 and creating a function that does the check for us. The benefit of this function is that it can be reusable through out your project to check any array of objects given the key

From The Definitive Guide to Django: Web Development Done Right:
If you’ve used Python before, you may be wondering why we’re running
python manage.py shell
instead of justpython
. Both commands will start the interactive interpreter, but themanage.py shell
command has one key difference: before starting the interpreter, it tells Django which settings file to use.
Use Case: Many parts of Django, including the template system, rely on your settings, and you won’t be able to use them unless the framework knows which settings to use.
If you’re curious, here’s how it works behind the scenes. Django looks for an environment variable called
DJANGO_SETTINGS_MODULE
, which should be set to the import path of your settings.py. For example,DJANGO_SETTINGS_MODULE
might be set to'mysite.settings'
, assuming mysite is on your Python path.When you run
python manage.py shell
, the command takes care of settingDJANGO_SETTINGS_MODULE
for you.**
function deleteItem(this) {
if (confirm("Are you sure?")) {
$(this).remove();
}
return false;
}
You can also use jquery modalin same way
JQuery version
Are you sure? $(document).ready(function() {
$("#dialog-box").dialog({
autoOpen: false,
modal: true
});
$(".close").click(function(e) {
var currentElem = $(this);
$("#dialog-box").dialog({
buttons : {
"Confirm" : function() {
currentElem.remove()
},
"Cancel" : function() {
$(this).dialog("close");
}
}
});
$("#dialog-box").dialog("open");
});
});
The proper data type for "2010-12-20 00:00:00.0000000" value is DATETIME2(7) / DT_DBTIME2 ().
But used data type for CYCLE_DATE field is DATETIME - DT_DATE. This means milliseconds precision with accuracy down to every third millisecond (yyyy-mm-ddThh:mi:ss.mmL where L can be 0,3 or 7).
The solution is to change CYCLE_DATE date type to DATETIME2 - DT_DBTIME2.
EDIT: Updated for jQuery 1.8
Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: Added code to make it a jQuery function.
For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
'-moz-transform' : 'rotate('+ degrees +'deg)',
'-ms-transform' : 'rotate('+ degrees +'deg)',
'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.
Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.
Here is a jsFiddle.
If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.
HTML
<div class="rotate">
<h1>Rotatey text</h1>
</div>
CSS
/* Totally for style */
.rotate {
background: #F02311;
color: #FFF;
width: 200px;
height: 200px;
text-align: center;
font: normal 1em Arial;
position: relative;
top: 50px;
left: 50px;
}
/* The real code */
.rotated {
-webkit-transform: rotate(45deg); /* Chrome, Safari 3.1+ */
-moz-transform: rotate(45deg); /* Firefox 3.5-15 */
-ms-transform: rotate(45deg); /* IE 9 */
-o-transform: rotate(45deg); /* Opera 10.50-12.00 */
transform: rotate(45deg); /* Firefox 16+, IE 10+, Opera 12.10+ */
}
jQuery
Make sure these are wrapped in $(document).ready
$('.rotate').click(function() {
$(this).toggleClass('rotated');
});
Custom intervals
var rotation = 0;
$('.rotate').click(function() {
rotation += 5;
$(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
'-moz-transform' : 'rotate('+ rotation +'deg)',
'-ms-transform' : 'rotate('+ rotation +'deg)',
'transform' : 'rotate('+ rotation +'deg)'});
});
It's easier to use jquery $(parent).html(code)
instead of parent.innerHTML = code
:
var oldDocumentWrite = document.write;
var oldDocumentWriteln = document.writeln;
try {
document.write = function(code) {
$(parent).append(code);
}
document.writeln = function(code) {
document.write(code + "<br/>");
}
$(parent).html(html);
} finally {
$(window).load(function() {
document.write = oldDocumentWrite
document.writeln = oldDocumentWriteln
})
}
This also works with scripts that use document.write
and scripts loaded via src
attribute. Unfortunately even this doesn't work with Google AdSense scripts.
hope this help you or Ctrl + Alt + Shift + S => select Dependencies tab and find what you need ( see my image)
Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.
A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt
and jshint
.
These lines add more meaning
Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.
Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:
There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.
Please Note that grunt plugin is also an npm package.
Question-1
When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json
It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.
Question-2
When should I ever install packages explicitly like that without adding them to the file that manages dependencies
It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request
, then you have two options:
OR
npm install --save request
--save
options adds the dependency to package.json file as well. If you don't specify --save
option, it will only download the package but the json file will be unaffected.
You can do this either way, there will not be a substantial difference.
You can use .toString
method to convert Uri to String in java
Uri uri = Uri.parse("Http://www.google.com");
String url = uri.toString();
This method convert Uri to String easily
Nowadays (2016) in Chrome Dev Tools console, you can quickly execute this function below to show all event listeners that have been attached to an element.
getEventListeners(document.querySelector('your-element-selector'));
Centerlized Model: You can use it from any where!
You just need to call Below Format From your function to this class
DataSet ds = new DataSet();
SqlParameter[] p = new SqlParameter[1];
string Query = "Describe Query Information/either sp, text or TableDirect";
DbConnectionHelper dbh = new DbConnectionHelper ();
ds = dbh. DBConnection("Here you use your Table Name", p , string Query, CommandType.StoredProcedure);
That's it. it's perfect method.
public class DbConnectionHelper {
public DataSet DBConnection(string TableName, SqlParameter[] p, string Query, CommandType cmdText) {
string connString = @ "your connection string here";
//Object Declaration
DataSet ds = new DataSet();
SqlConnection con = new SqlConnection();
SqlCommand cmd = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter();
try {
//Get Connection string and Make Connection
con.ConnectionString = connString; //Get the Connection String
if (con.State == ConnectionState.Closed) {
con.Open(); //Connection Open
}
if (cmdText == CommandType.StoredProcedure) //Type : Stored Procedure
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = Query;
if (p.Length > 0) // If Any parameter is there means, we need to add.
{
for (int i = 0; i < p.Length; i++) {
cmd.Parameters.Add(p[i]);
}
}
}
if (cmdText == CommandType.Text) // Type : Text
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = Query;
}
if (cmdText == CommandType.TableDirect) //Type: Table Direct
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = Query;
}
cmd.Connection = con; //Get Connection in Command
sda.SelectCommand = cmd; // Select Command From Command to SqlDataAdaptor
sda.Fill(ds, TableName); // Execute Query and Get Result into DataSet
con.Close(); //Connection Close
} catch (Exception ex) {
throw ex; //Here you need to handle Exception
}
return ds;
}
}
My 2 cents here: using Java8 Streams + checking an exact string:
public enum MyEnum {
VALUE_1("Super"),
VALUE_2("Rainbow"),
VALUE_3("Dash"),
VALUE_3("Rocks");
private final String value;
MyEnum(String value) {
this.value = value;
}
/**
* @return the Enum representation for the given string.
* @throws IllegalArgumentException if unknown string.
*/
public static MyEnum fromString(String s) throws IllegalArgumentException {
return Arrays.stream(MyEnum.values())
.filter(v -> v.value.equals(s))
.findFirst()
.orElseThrow(() -> new IllegalArgumentException("unknown value: " + s));
}
}
** EDIT **
Renamed the function to fromString()
since naming it using that convention, you'll obtain some benefits from Java language itself; for example:
.search-table-outter {border:2px solid red; overflow-x:scroll;}
.search-table{table-layout: fixed; margin:40px auto 0px auto; }
.search-table, td, th{border-collapse:collapse; border:1px solid #777;}
th{padding:20px 7px; font-size:15px; color:#444; background:#66C2E0;}
td{padding:5px 10px; height:35px;}
You should provide scroll in div.
I think the only way to handle this is to use JavaScript
Try this Invert text color of a specific element
If you do this with css3 it's only compatible with the newest browser versions.
This is just "hack" style method:
int d[][] = new int[n][n];
static int swap(int a, int b) {
return a;
}
...
in main class -->
d[i][j + 1] = swap(d[i][j], d[i][j] = d[i][j + 1])
This problem can occur if a class tries to get value of a non-existent key in web.config
.
For example, the class has a static variable ClientID
private static string ClientID = System.Configuration.ConfigurationSettings.AppSettings["GoogleCalendarApplicationClientID"].ToString();
but the web.config
doesn't contain the 'GoogleCalendarApplicationClientID' key, then the error will be thrown on any static function call or any class instance creation
There is pretty concise and easy way:
Response.Write("<script>alert('Your text');</script>");
Quickest way to convert .ui to .py is from terminal:
pyuic4 -x input.ui -o output.py
Make sure you have pyqt4-dev-tools installed.
To fix this issue I spent a full night. Here's my two cents on this story,
Check if you are using hhvm as php interpreter. Then it's possible that it's listening on port 9000 so you will have to modify your web server's config.
This is a side note: If you are using mysql, and connections from hhvm to the mysql become impossible, check if you have apparmor installed. disable it.
If you work with data that doesn't need construction/destruction and requires reallocations (e.g., a large array of ints), then I believe malloc/free is a good choice as it gives you realloc, which is way faster than new-memcpy-delete (it is on my Linux box, but I guess this may be platform dependent). If you work with C++ objects that are not POD and require construction/destruction, then you must use the new and delete operators.
Anyway, I don't see why you shouldn't use both (provided that you free your malloced memory and delete objects allocated with new) if can take advantage of the speed boost (sometimes a significant one, if you're reallocing large arrays of POD) that realloc can give you.
Unless you need it though, you should stick to new/delete in C++.
Here's a compact way to do something different in all four cases:
if(empty($youtube)) {
if(empty($link)) {
# both empty
} else {
# only $youtube not empty
}
} else {
if(empty($link)) {
# only $link empty
} else {
# both not empty
}
}
If you want to use an expression instead, you can use ?:
instead:
echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
: ( empty($link) ? 'only $link empty' : 'both not empty' );

How to find -
Eg - In my case i created 30 instances of winston log Unknowingly and it started giving error
Note : if u supress this error , it will come again afetr 3..4 days
You could replace something in there by getting the index along with the item.
>>> foo = ['a', 'b', 'c', 'A', 'B', 'C']
>>> for index, item in enumerate(foo):
... print(index, item)
...
(0, 'a')
(1, 'b')
(2, 'c')
(3, 'A')
(4, 'B')
(5, 'C')
>>> for index, item in enumerate(foo):
... if item in ('a', 'A'):
... foo[index] = 'replaced!'
...
>>> foo
['replaced!', 'b', 'c', 'replaced!', 'B', 'C']
Note that if you want to remove something from the list you have to iterate over a copy of the list, else you will get errors since you're trying to change the size of something you are iterating over. This can be done quite easily with slices.
Wrong:
>>> foo = ['a', 'b', 'c', 1, 2, 3]
>>> for item in foo:
... if isinstance(item, int):
... foo.remove(item)
...
>>> foo
['a', 'b', 'c', 2]
The 2 is still in there because we modified the size of the list as we iterated over it. The correct way would be:
>>> foo = ['a', 'b', 'c', 1, 2, 3]
>>> for item in foo[:]:
... if isinstance(item, int):
... foo.remove(item)
...
>>> foo
['a', 'b', 'c']
On osx 10.10.5 and in a virtualenv, maybe you can resolve that problem like below:
sudo C_INCLUDE_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/libxml:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include pip install -r lxml
i tried everything/....but only this thing worked for me:
To fix this, I went to help - Install New Software... - from the "work with" drop-down box I selected http://dl-ssl.google.com/android/eclipse/ - I then check marked "Developer Tools" and hit the Next button. I then followed the prompts and it basically did a re-install. It took less than 5 minutes. That resolved the error.
Now Im back up and running, and I got the lastest version of Eclipse.
Thanks a lot Nadir

All the other answers are great, but I find it best to understand them by breaking down files into three categories: unstaged
, staged
, commit
:
--hard
should be easy to understand, it restores everything--mixed
(default) :
unstaged
files: don't changestaged
files: move to unstaged
commit
files: move to unstaged
--soft
:
unstaged
files: don't changestaged
files: dont' changecommit
files: move to staged
In summary:
--soft
option will move everything (except unstaged
files) into staging area
--mixed
option will move everything into unstaged area

Ther is no simple way to do it, but you can use your own function like answered below.
A good thing to remember are these simple rules, and they apply to both parameters and return types...
There is a time and place for each, so make sure you get to know them. Local variables, as you've shown here, are just that, limited to the time they are locally alive in the function scope. In your example having a return type of int*
and returning &i
would have been equally incorrect. You would be better off in that case doing this...
void func1(int& oValue)
{
oValue = 1;
}
Doing so would directly change the value of your passed in parameter. Whereas this code...
void func1(int oValue)
{
oValue = 1;
}
would not. It would just change the value of oValue
local to the function call. The reason for this is because you'd actually be changing just a "local" copy of oValue
, and not oValue
itself.

I encountered the same problem whilst trying to get Shinken 2.0.3 to fire up on Ubuntu. Eventually I did a full uninstall then reinstalled Shinken with pip -v
. As it cleaned up, it mentioned:
Warning: missing python-pycurl lib, you MUST install it before launch the shinken daemons
Installed that with apt-get
, and all the brokers fired up as expected :-)

I've never really seen a point in using it. Provides very little advantage, and might even make things harder to use.
Unless you happen to have hundreds or thousands of links, all to the same sub-directory. Then it might save you a few bytes of bandwidth.
As an afterthought, I seem to recall there being some problem with the tag in IE6. You could place them anywhere in the body, redirecting different portions of the site to different locations. This was fixed in IE7, which broke a lot of sites.
Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>
You are not initializing your String[]
. You either need to initialize it using the exact array size, as suggested by @Tr?nSiLong, or use a List<String>
and then convert to a String[]
(in case you do not know the length):
String[] title = {
"Abundance",
"Anxiety",
"Bruxism",
"Discipline",
"Drug Addiction"
};
String urlbase = "http://www.somewhere.com/data/";
String imgSel = "/logo.png";
List<String> mStrings = new ArrayList<String>();
for(int i=0;i<title.length;i++) {
mStrings.add(urlbase + title[i].toLowerCase() + imgSel);
System.out.println(mStrings[i]);
}
String[] strings = new String[mStrings.size()];
strings = mStrings.toArray(strings);//now strings is the resulting array
Enum.IsDefined will get things done. It may not be as efficient as a TryParse would probably be, but it will work without exception handling.
public static TEnum ToEnum<TEnum>(this string strEnumValue, TEnum defaultValue)
{
if (!Enum.IsDefined(typeof(TEnum), strEnumValue))
return defaultValue;
return (TEnum)Enum.Parse(typeof(TEnum), strEnumValue);
}
Worth noting: a TryParse
method was added in .NET 4.0.
Since strings support adding, you can easily add your new style without overriding the current:
document.getElementById("myElement").style.cssText += `
font-size: 12px;
left: 200px;
top: 100px;
`;
Another way of doing multiple cases in a switch statement, when inside a function:
function name(varName){
switch (varName) {
case 'afshin':
case 'saeed':
case 'larry':
return 'Hey';
default:
return 'Default case';
}
}
console.log(name('afshin')); // Hey
_x000D_
pyspark.sql.Column.contains()
is only available in pyspark version 2.2 and above.
df.where(df.location.contains('google.com'))
This worked for me as well:
Get-ADUser -Filter * -SearchBase "ou=OU,dc=Domain,dc=com" -Properties Enabled, CanonicalName, Displayname, Givenname, Surname, EmployeeNumber, EmailAddress, Department, StreetAddress, Title | select Enabled, CanonicalName, Displayname, GivenName, Surname, EmployeeNumber, EmailAddress, Department, Title | Export-CSV "C:\output.csv"
After you shelled to the Docker container, just type:
apt-get update
apt-get install nano
It is quite easy to do using the Array.findIndex
function, which takes a function as an argument:
var arrayObj = [{name:"bull", text: "sour"},
{ name: "tom", text: "tasty" },
{ name: "tom", text: "tasty" }
]
var index = arrayObj.findIndex(x => x.name=="bob");
// here you can check specific property for an object whether it exist in your array or not
index === -1 ? arrayObj.push({your_object}) : console.log("object already exists")
This topic, especially the answer of Xotic750 was very helpful to me. I wanted to generate a json variable to pass it to a php script using ajax. My values were stored into two arrays, and i wanted them in json format. This is a generic example:
valArray1 = [121, 324, 42, 31];
valArray2 = [232, 131, 443];
myJson = {objArray1: {}, objArray2: {}};
for (var k = 1; k < valArray1.length; k++) {
var objName = 'obj' + k;
var objValue = valArray1[k];
myJson.objArray1[objName] = objValue;
}
for (var k = 1; k < valArray2.length; k++) {
var objName = 'obj' + k;
var objValue = valArray2[k];
myJson.objArray2[objName] = objValue;
}
console.log(JSON.stringify(myJson));
The result in the console Log should be something like this:
{
"objArray1": {
"obj1": 121,
"obj2": 324,
"obj3": 42,
"obj4": 31
},
"objArray2": {
"obj1": 232,
"obj2": 131,
"obj3": 443
}
}
Use FLOOR(), if you want to round your decimal to the lower integer. Examples:
FLOOR(1.9) => 1
FLOOR(1.1) => 1
Use ROUND(), if you want to round your decimal to the nearest integer. Examples:
ROUND(1.9) => 2
ROUND(1.1) => 1
Use CEIL(), if you want to round your decimal to the upper integer. Examples:
CEIL(1.9) => 2
CEIL(1.1) => 2
It seems that without return()
it's faster...

Definitely the HTML5 element is the way to go. There's at least basic support for it in the most recent versions of almost all browsers:
http://caniuse.com/#feat=audio
And it allows to specify what to do when the element is not supported by the browser. For example you could add a link to a file by doing:
<audio controls src="intro.mp3">
<a href="intro.mp3">Introduction to HTML5 (10:12) - MP3 - 3.2MB</a>

You can find this examples and more information about the audio element in the following link:

I ended up on this question when searching for an api to decode url in a win32 c++ app. Since the question doesn't quite specify platform assuming windows isn't a bad thing.
InternetCanonicalizeUrl is the API for windows programs. More info here
LPTSTR lpOutputBuffer = new TCHAR[1];
DWORD dwSize = 1;
BOOL fRes = ::InternetCanonicalizeUrl(strUrl, lpOutputBuffer, &dwSize, ICU_DECODE | ICU_NO_ENCODE);
DWORD dwError = ::GetLastError();
if (!fRes && dwError == ERROR_INSUFFICIENT_BUFFER)
{
delete lpOutputBuffer;
lpOutputBuffer = new TCHAR[dwSize];
fRes = ::InternetCanonicalizeUrl(strUrl, lpOutputBuffer, &dwSize, ICU_DECODE | ICU_NO_ENCODE);
if (fRes)
{
//lpOutputBuffer has decoded url
}
else
{
//failed to decode
}
if (lpOutputBuffer !=NULL)
{
delete [] lpOutputBuffer;
lpOutputBuffer = NULL;
}
}
else
{
//some other error OR the input string url is just 1 char and was successfully decoded
}
InternetCrackUrl (here) also seems to have flags to specify whether to decode url
It's the new feature in C# 6 called Interpolated Strings
.
The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.
For more details about this, please take a look at MSDN.
Now, think a little bit more about it. Why this feature is great?
For example, you have class Point
:
public class Point
{
public int X { get; set; }
public int Y { get; set; }
}
Create 2 instances:
var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };
Now, you want to output it to the screen. The 2 ways that you usually use:
Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");
As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format()
to make it nicer:
Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));
This creates a new problem:
For those reasons, we should use new feature:
Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");
The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.
For the full post, please read this blog.
// I'd modify this slightly to be more resilient to a bad parameter
// it will handle your case and better handle other cases given to it:
int index = 25;
if (index >= 0 && index < array.Length)
{
// Array element found
}
From C# 6.0 onwards (Visual Studio 2015 and newer), you can simply use an interpolated string with formatting:
var date = new DateTime(2017, 8, 3);
var formattedDate = $"{date:dd-MM-yyyy}";
Accepted answer didn't work for me, this does:

Most of these answers use sp_executesql as the solution to this problem. I have found that there are some limitations when using sp_executesql, which I will not go into, but I wanted to offer an alternative using EXEC(). I am using SQL Server 2008 and I know that some of the objects I am using in this script are not available in earlier versions of SQL Server so be wary.
DECLARE @CountResults TABLE (CountReturned INT)
DECLARE
@SqlStatement VARCHAR(8000) = 'SELECT COUNT(*) FROM table'
, @Count INT
INSERT @CountResults
EXEC(@SqlStatement)
SET @Count = (SELECT CountReturned FROM @CountResults)
SELECT @Count
Don't use getApplicationContext()

Always use this
or your activity.this
Checkout this thread, it has some useful information about exiting and tracebacks.
If you are more interested in just killing the program, try something like this (this will take the legs out from under the cleanup code as well):
if __name__ == '__main__':
try:
main()
except KeyboardInterrupt:
print('Interrupted')
try:
sys.exit(0)
except SystemExit:
os._exit(0)
Try this Example
class InvalidInputError(Exception):
def __init__(self, msg):
self.msg = msg
def __str__(self):
return repr(self.msg)
inp = int(input("Enter a number between 1 to 10:"))
try:
if type(inp) != int or inp not in list(range(1,11)):
raise InvalidInputError
except InvalidInputError:
print("Invalid input entered")
COUNT(*)
are optimized in MySQL, so the former query is likely to be faster, generally speaking.
I'm having a very similar problem. In the past, this has been related to serialization problems. If you are still having this problem, can you verify that you can correctly serialize the objects you are returning. Specifically, if you are using Linq-To-Sql objects that have relationships, there are known serialization problems if you put a back reference on a child object to the parent object and mark that back reference as a DataMember.
You can verify serialization by writing a console app that serializes and deserializes your objects using the DataContractSerializer on the server side and whatever serialization methods your client uses. For example, in our current application, we have both WPF and Compact Framework clients. I wrote a console app to verify that I can serialize using a DataContractSerializer and deserialize using an XmlDesserializer. You might try that.
Also, if you are returning Linq-To-Sql objects that have child collections, you might try to ensure that you have eagerly loaded them on the server side. Sometimes, because of lazy loading, the objects being returned are not populated and may cause the behavior you are seeing where the request is sent to the service method multiple times.
If you have solved this problem, I'd love to hear how because I'm stuck with it too. I have verified that my issue is not serialization so I'm at a loss.
UPDATE: I'm not sure if it will help you any but the Service Trace Viewer Tool just solved my problem after 5 days of very similar experience to yours. By setting up tracing and then looking at the raw XML, I found the exceptions that were causing my serialization problems. It was related to Linq-to-SQL objects that occasionally had more child objects than could be successfully serialized. Adding the following to your web.config file should enable tracing:
<sharedListeners>
<add name="sharedListener"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData="c:\Temp\servicetrace.svclog" />
</sharedListeners>
<sources>
<source name="System.ServiceModel" switchValue="Verbose, ActivityTracing" >
<listeners>
<add name="sharedListener" />
</listeners>
</source>
<source name="System.ServiceModel.MessageLogging" switchValue="Verbose">
<listeners>
<add name="sharedListener" />
</listeners>
</source>
</sources>
The resulting file can be opened with the Service Trace Viewer Tool or just in IE to examine the results.
for React users
e.target.value = ""
But if the file input element is triggered by a different element (with a htmlFor
attribute) - that will mean u don't have the event
So you could use a ref:
at beginning of func:
const inputRef = React.useRef();
on input element
<input type="file" ref={inputRef} />
and then on an onClick function (for example) u may write
inputRef.current.value = ""
this.inputRef = React.createRef()
you can use val function to collect data from inputs:
jQuery("#myInput1").val();
You can use the CONCAT
function like this:
SELECT CONCAT(`SUBJECT`, ' ', `YEAR`) FROM `table`
Update:
To get that result you can try this:
SET @rn := 0;
SELECT CONCAT(`SUBJECT`,'-',`YEAR`,'-',LPAD(@rn := @rn+1,3,'0'))
FROM `table`
with(dfr[dfr$var3 < 155,], plot(var1, var2))
should do the trick.
Edit regarding multiple conditions:
with(dfr[(dfr$var3 < 155) & (dfr$var4 > 27),], plot(var1, var2))
Though OP is asking about Windows, this error also occurs on Ubuntu Linux and Google lists this result first when you search for the error"QtCreator: No valid kits found".
On Ubuntu this is solved by running:
For Qt5:
sudo apt-get install qt5-default
For Qt4:
sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui
This question is answered here and here, though those entries are less SEO-friendly...

You can use a TextView or your custom TextView. The latter is when the textview cannot get focus all the time.
First, you can use a TextView or a custom TextView as the scrolling text view in your layout .xml file like this:
<com.example.myapplication.CustomTextView
android:id="@+id/tvScrollingMessage"
android:text="@string/scrolling_message_main_wish_list"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit ="marquee_forever"
android:focusable="true"
android:focusableInTouchMode="true"
android:scrollHorizontally="true"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="@color/black"
android:gravity="center"
android:textColor="@color/white"
android:textSize="15dp"
android:freezesText="true"/>
NOTE: in the above code snippet com.example.myapplication is an example package name and should be replaced by your own package name.
Then in case of using CustomTextView, you should define the CustomTextView class:
public class CustomTextView extends TextView {
public CustomTextView(Context context) {
super(context);
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(focused)
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public void onWindowFocusChanged(boolean focused) {
if(focused)
super.onWindowFocusChanged(focused);
}
@Override
public boolean isFocused() {
return true;
}
}
Hope it will be helpful to you. Cheers!
Why don't you try sudo
with the H
flag? This should do the trick.
sudo -H pip install flake8
A regular sudo pip install flake8
will try to use your own home directory. The -H
instructs it to use the system's home directory. More info at https://stackoverflow.com/a/43623102/
