I think that your problem is in the location of the image. You shall place it in your source, and then use it like this:
JButton button = new JButton();
try {
Image img = ImageIO.read(getClass().getResource("resources/water.bmp"));
button.setIcon(new ImageIcon(img));
} catch (Exception ex) {
System.out.println(ex);
}
In this example, it is assumed that image is in src/resources/ folder.
The best way to access files from resource folder inside a jar is it to use the InputStream via getResourceAsStream
. If you still need a the resource as a file instance you can copy the resource as a stream into a temporary file (the temp file will be deleted when the JVM exits):
public static File getResourceAsFile(String resourcePath) {
try {
InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
if (in == null) {
return null;
}
File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
tempFile.deleteOnExit();
try (FileOutputStream out = new FileOutputStream(tempFile)) {
//copy stream
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = in.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
}
}
return tempFile;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
Just another case. I copied a solution with two projects and renamed them partially in the Windows explorer (folder names, .sln and .csproj file names) and partially with a massive Find & Replace action in Visual Studio (namespaces etc.). Nevertheless the exception stated by the OP still occurred. I found out that the Assembly and Namespace names were still old.
Although the project and everything else was already named OfficeStyle the Assembly name
and Default namespace
were still named Linckus.
After this correction everything worked fine again, compile and run time :)
In my case I finally made it with
import java.lang.Thread;
import java.io.BufferedReader;
import java.io.InputStreamReader;
final BufferedReader in = new BufferedReader(new InputStreamReader(
Thread.currentThread().getContextClassLoader().getResourceAsStream("file.txt"))
); // no initial slash in file.txt
If you want to use LINQ, use resourceSet.OfType<DictionaryEntry>()
. Using LINQ allows you, for example, to select resources based on their index (int) instead of key (string):
ResourceSet resourceSet = Resources.ResourceManager.GetResourceSet(CultureInfo.CurrentUICulture, true, true);
foreach (var entry in resourceSet.OfType<DictionaryEntry>().Select((item, i) => new { Index = i, Key = item.Key, Value = item.Value }))
{
Console.WriteLine(@"[{0}] {1}", entry.Index, entry.Key);
}
By all your powers combined I use this helper class for reading resources from any assembly and any namespace in a generic way.
public class ResourceReader
{
public static IEnumerable<string> FindEmbededResources<TAssembly>(Func<string, bool> predicate)
{
if (predicate == null) throw new ArgumentNullException(nameof(predicate));
return
GetEmbededResourceNames<TAssembly>()
.Where(predicate)
.Select(name => ReadEmbededResource(typeof(TAssembly), name))
.Where(x => !string.IsNullOrEmpty(x));
}
public static IEnumerable<string> GetEmbededResourceNames<TAssembly>()
{
var assembly = Assembly.GetAssembly(typeof(TAssembly));
return assembly.GetManifestResourceNames();
}
public static string ReadEmbededResource<TAssembly, TNamespace>(string name)
{
if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));
return ReadEmbededResource(typeof(TAssembly), typeof(TNamespace), name);
}
public static string ReadEmbededResource(Type assemblyType, Type namespaceType, string name)
{
if (assemblyType == null) throw new ArgumentNullException(nameof(assemblyType));
if (namespaceType == null) throw new ArgumentNullException(nameof(namespaceType));
if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));
return ReadEmbededResource(assemblyType, $"{namespaceType.Namespace}.{name}");
}
public static string ReadEmbededResource(Type assemblyType, string name)
{
if (assemblyType == null) throw new ArgumentNullException(nameof(assemblyType));
if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));
var assembly = Assembly.GetAssembly(assemblyType);
using (var resourceStream = assembly.GetManifestResourceStream(name))
{
if (resourceStream == null) return null;
using (var streamReader = new StreamReader(resourceStream))
{
return streamReader.ReadToEnd();
}
}
}
}
I found to be the best practice of using images, videos, etc. is:

I had the same problem, but a different solution was called for. The problem in this case was the class of the File Owner was not connected to xib file.

Some Google services do not like to be used to much. Quite recently my account was locked because of script, which was sending two e-mails per second to the same user. Google considered it as a spam. So using sleep here is also justified to prevent such situations.
Loosely:
Declarative programming tends towards:-
Imperative programming tends towards:-
As a result, an imperative style helps the reader to understand the mechanics of what the system is actually doing, but may give little insight into the problem that it is intended to solve. On the other hand, a declarative style helps the reader to understand the problem domain and the approach that the system takes towards the solution of the problem, but is less informative on the matter of mechanics.
Real programs (even ones written in languages that favor the ends of the spectrum, such as ProLog or C) tend to have both styles present to various degrees at various points, to satisfy the varying complexities and communication needs of the piece. One style is not superior to the other; they just serve different purposes, and, as with many things in life, moderation is key.
In Font Awesome 5 it can be done using pure CSS as in some of the above answers with some modifications.
ul {
list-style-type: none;
}
li:before {
position: absolute;
font-family: 'Font Awesome 5 free';
/* Use the Name of the Font Awesome free font, e.g.:
- 'Font Awesome 5 Free' for Regular and Solid symbols;
- 'Font Awesome 5 Brand' for Brands symbols.
- 'Font Awesome 5 Pro' for Regular and Solid symbols (Professional License);
*/
content: "\f1fc"; /* Unicode value of the icon to use: */
font-weight: 900; /* This is important, change the value according to the font family name
used above. See the link below */
color: red;
}
Without the correct font-weight, it will only show a blank square.

Try using GET method,
var request = $.ajax({
url: 'url',
type: 'GET',
data: { field1: "hello", field2 : "hello2"} ,
contentType: 'application/json; charset=utf-8'
});
request.done(function(data) {
// your success code here
});
request.fail(function(jqXHR, textStatus) {
// your failure code here
});
You cannot see parameters in URL with POST method.
Edit:
Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.
No - but technically there is a work-around (not that i'd actually use it unless forced to):
for(struct { int a; char b; } s = { 0, 'a' } ; s.a < 5 ; ++s.a)
{
std::cout << s.a << " " << s.b << std::endl;
}
It is as easy as specifying a padding bottom the same size as the width in percent. So if you have a width of 50%, just use this example below
id or class{
width: 50%;
padding-bottom: 50%;
}

The answers were useful. After the change, I got duplicate logging of SQL statements, one in the log4j log file and one on the standard console. I changed the persistence.xml file to say show_sql to false to get rid of logging from the standard console. Keeping format_sql true also affects the log4j log file, so I kept that true.

No need for jQuery! This simple snippet works fine for me. It uses angular.element() to bind window resize event.
/**
* Window resize event handling
*/
angular.element($window).on('resize', function () {
console.log($window.innerWidth);
});
/**
* Window resize unbind event
*/
angular.element($window).off('resize');
First, JavaScript's switch
is no faster than if/else
(and sometimes much slower).
Second, the only way to use switch
with multiple variables is to combine them into one primitive (string, number, etc) value:
var stateA = "foo";
var stateB = "bar";
switch (stateA + "-" + stateB) {
case "foo-bar": ...
...
}
But, personally, I would rather see a set of if
/else
statements.
Edit: When all the values are integers, it appears that switch can out-perform if/else in Chrome. See the comments.
Before you try the fancy stuff, try disabling the firewall and antivirus and see if it works. That was my problem.
I couldn't make any of the answers here to work. As a horrible hack, I store in local storage a timestamp when I change the route, and check at page initialization whether this timestamp is set and recent, in that case I don't trigger some initialization actions.
In controller:
window.localStorage['routeChangeWithoutReloadTimestamp'] = new Date().getTime();
$location.path(myURL);
In config:
.when(myURL, {
templateUrl: 'main.html',
controller:'MainCtrl',
controllerAs: 'vm',
reloadOnSearch: false,
resolve:
{
var routeChangeWithoutReloadTimestamp =
window.localStorage['routeChangeWithoutReloadTimestamp'];
var currentTimestamp = new Date().getTime();
if (!routeChangeWithoutReloadTimestamp ||
currentTimestamp - routeChangeWithoutReloadTimestamp >= 5000) {
//initialization code here
}
//reset the timestamp to trigger initialization when needed
window.localStorage['routeChangeWithoutReloadTimestamp'] = 0;
}
});
I used a timestamp rather than a boolean, just in case the code is interrupted before having a chance to reinit the value stored before changing route. The risk of collision between tabs is very low.
"\n" = new line
'\n' = \n
"\t" = tab
'\t' = \t
RewriteEngine on
RewriteBase /basic_test/
RewriteRule ^index.php$ test.php
[^]
should match any character, including newline. [^
CHARS]
matches all characters except for those in CHARS. If CHARS is empty, it matches all characters.
JavaScript example:
/a[^]*Z/.test("abcxyz \0\r\n\t012789ABCXYZ") // Returns ‘true’.
Use this simple script that centers the modals.
If you want you can set a custom class (ex: .modal.modal-vcenter instead of .modal) to limit the functionality only to some modals.
var modalVerticalCenterClass = ".modal";
function centerModals($element) {
var $modals;
if ($element.length) {
$modals = $element;
} else {
$modals = $(modalVerticalCenterClass + ':visible');
}
$modals.each( function(i) {
var $clone = $(this).clone().css('display', 'block').appendTo('body');
var top = Math.round(($clone.height() - $clone.find('.modal-content').height()) / 2);
top = top > 0 ? top : 0;
$clone.remove();
$(this).find('.modal-content').css("margin-top", top);
});
}
$(modalVerticalCenterClass).on('show.bs.modal', function(e) {
centerModals($(this));
});
$(window).on('resize', centerModals);
Also add this CSS fix for the modal's horizontal spacing; we show the scroll on the modals, the body scrolls is hidden automatically by Bootstrap:
/* scroll fixes */
.modal-open .modal {
padding-left: 0px !important;
padding-right: 0px !important;
overflow-y: scroll;
}
The easiest way would be not to pass bars
through the different functions, but to access it directly from maptest
:
foos = [1.0,2.0,3.0,4.0,5.0]
bars = [1,2,3]
def maptest(foo):
print foo, bars
map(maptest, foos)
With your original maptest
function you could also use a lambda function in map
:
map((lambda foo: maptest(foo, bars)), foos)
Each time the same will be generated:
if let uuid = UIDevice.current.identifierForVendor?.uuidString {
print(uuid)

Each time a new one will be generated:
let uuid = UUID().uuidString
print(uuid)
Google will eventually block your IP when you exceed a certain amount of requests.
All you have to do is add:
#include <string>
using namespace std;
at the top. (BTW I know this was posted in 2013 but I just wanted to answer)
I had this problem - I eventually worked out that the reason was that I'd included \
characters in the string. If you have any of these, "escape" them with \\
and it should work fine.
I don't believe the expression is sensical as it is.
Elvis means "if truthy, use the value, else use this other thing."
Your "other thing" is a closure, and the value is status != null
, neither of which would seem to be what you want. If status
is null, Elvis says true
. If it's not, you get an extra layer of closure.
Why can't you just use:
(it.description == desc) && ((status == null) || (it.status == status))
Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find
calls, just use an intermediate variable.

If you are sure that you selected the Generic iOS device

This was the missing solution for me as a cordova developer with Xcode 11.2
You can use, which will be triggered when the window resizes.
$( window ).bind("resize", function(){
// Change the width of the div
$("#yourdiv").width( 600 );
});
If you want a DIV width as percentage of the screen, just use CSS width : 80%;
.
Had this issue just today and discovered that I inadvertently left off the @ManyToMany annotation above the @JoinTable annotation.
When working collaboratively, or on multiple features at once, it's common that the upstream or even your master contains work that is not included in your branch, and will incorrectly appear in basic diffs.
If your Upstream may have moved, you should do this:
git fetch
git diff origin/master...
Just using git diff master can include, or fail to include, relevant changes.
No, it doesn't uninstall the dependencies packages. It only removes the specified package:
$ pip install specloud
$ pip freeze # all the packages here are dependencies of specloud package
figleaf==0.6.1
nose==1.1.2
pinocchio==0.3
specloud==0.4.5
$ pip uninstall specloud
$ pip freeze
figleaf==0.6.1
nose==1.1.2
pinocchio==0.3
As you can see those packages are dependencies from specloud
and they're still there, but not the specloud
package itself.
As mentioned below, You can install and use the pip-autoremove utility to remove a package plus unused dependencies.
If none of the solution worked and you are working with JAXB, then you need to annotate your class with @XmlRootElement

Hibernate defines five types of identifier generation strategies:
AUTO - either identity column, sequence or table depending on the underlying DB
TABLE - table holding the id
IDENTITY - identity column
SEQUENCE - sequence
identity copy – the identity is copied from another entity
Example using Table
@Id
@GeneratedValue(strategy=GenerationType.TABLE , generator="employee_generator")
@TableGenerator(name="employee_generator",
table="pk_table",
pkColumnName="name",
valueColumnName="value",
allocationSize=100)
@Column(name="employee_id")
private Long employeeId;
for more details, check the link.
Set the auto complete:

event.preventDefault();
Stops the default action of an element from happening.
event.stopPropagation();
Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
For example, if there is a link with a click method attached inside of a DIV
or FORM
that also has a click method attached, it will prevent the DIV
or FORM
click method from firing.
One method I did with mine, is to "Add to Source Control", and select 'Git'.
To get unique items from an array and preserve their order, you can use .NET HashSet:
$Array = @(1, 3, 1, 2)
$Set = New-Object -TypeName 'System.Collections.Generic.HashSet[int]' -ArgumentList (,[int[]]$Array)
# PS>$Set
# 1
# 3
# 2
Works best with string arrays that contain both uppercase and lowercase items where you need to preserve first occurrence of each item in case-insensitive manner:
$Array = @("B", "b", "a", "A")
$Set = New-Object -TypeName 'System.Collections.Generic.HashSet[string]' -ArgumentList ([string[]]$Array, [StringComparer]::OrdinalIgnoreCase)
# PS>$Set
# B
# a
Works as expected with other types.
Shortened syntax, compatible with PowerShell 5.1 and newer:
$Array = @("B", "b", "a", "A")
$Set = [Collections.Generic.HashSet[string]]::new([string[]]$Array, [StringComparer]::OrdinalIgnoreCase)
$Array = @(1, 3, 1, 2)
$Set = [Collections.Generic.HashSet[int]]::new([int[]]$Array)
I'm using Bootstrap 4 (Beta 2). Meanwhile the situations seems to have changed. I had the same problem and found an easy solution. This is my code:
<div class="container-fluid content-row">
<div class="row">
<div class="col-sm-12 col-lg-6">
<div class="card h-100">
… content card …
</div>
</div>
… all the other cards …
</div>
</div>
With "col-sm-12 col-lg-6" I've made the cards responsive. With "card h-100" I've set all cards to the height of their parent column. On my system this works, but I'm not a pro. So, hopefully I helped someone.
In Swift 3.0
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
In older swift: Do something like this:
let screenSize: CGRect = UIScreen.mainScreen().bounds
then you can access the width and height like this:
let screenWidth = screenSize.width
let screenHeight = screenSize.height
if you want 75% of your screen's width you can go:
let screenWidth = screenSize.width * 0.75
Swift 4.0
// Screen width.
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
// Screen height.
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
In Swift 5.0
let screenSize: CGRect = UIScreen.main.bounds
Although this is a old post, I have spent 3 hours to fix my issue and I think this might help someone in future.
Here is my jquery-dialog
hack to show html content inside an <iframe>
:
let modalProperties = {autoOpen: true, width: 900, height: 600, modal: true, title: 'Modal Title'};
let modalHtmlContent = '<div>My Content First div</div><div>My Content Second div</div>';
// create wrapper iframe
let wrapperIframe = $('<iframe src="" frameborder="0" style="width:100%; height:100%;"></iframe>');
// create jquery dialog by a 'div' with 'iframe' appended
$("<div></div>").append(wrapperIframe).dialog(modalProperties);
// insert html content to iframe 'body'
let wrapperIframeDocument = wrapperIframe[0].contentDocument;
let wrapperIframeBody = $('body', wrapperIframeDocument);
wrapperIframeBody.html(modalHtmlContent);
You can do it with CSS.
Put the buttons in the markup with the Next
button first, then the Prev
button afterwards.
Then use CSS to position them to appear the way you want.
That is not possible, but you can add an anonymous initializer like this:
final int anInt = ...;
Object a = new Class1()
{
{
System.out.println(anInt);
}
void someNewMethod() {
}
};
Don't forget final on declarations of local variables or parameters used by the anonymous class, as i did it for anInt.
Enqueue means to add an element, dequeue to remove an element.
var stackInput= []; // First stack
var stackOutput= []; // Second stack
// For enqueue, just push the item into the first stack
function enqueue(stackInput, item) {
return stackInput.push(item);
}
function dequeue(stackInput, stackOutput) {
// Reverse the stack such that the first element of the output stack is the
// last element of the input stack. After that, pop the top of the output to
// get the first element that was ever pushed into the input stack
if (stackOutput.length <= 0) {
while(stackInput.length > 0) {
var elementToOutput = stackInput.pop();
stackOutput.push(elementToOutput);
}
}
return stackOutput.pop();
}
Less than or equal:
User.objects.filter(userprofile__level__lte=0)

The executor approach might seem familiar to all those who have gotten their hands dirty with Java before.
Also on a side note: To keep the universe sane, don't forget to close your pools/executors if you don't use with
context (which is so awesome that it does it for you)
You can do it in the following way:
myfxn <- function(var1,var2,var3){
var1*var2*var3
}
lapply(1:3,myfxn,var2=2,var3=100)
and you will get the answer:
[[1]] [1] 200
[[2]] [1] 400
[[3]] [1] 600
I had same issue, I resolved from below steps:
Here's my take:
timeSince(123456) => "1 day, 10 hours, 17 minutes, 36 seconds"
And the code:
function timeSince(date, longText) {
let seconds = null;
let leadingText = null;
if (date instanceof Date) {
seconds = Math.floor((new Date() - date) / 1000);
if (seconds < 0) {
leadingText = " from now";
} else {
leadingText = " ago";
}
seconds = Math.abs(seconds);
} else {
seconds = date;
leadingText = "";
}
const intervals = [
[31536000, "year" ],
[ 2592000, "month" ],
[ 86400, "day" ],
[ 3600, "hour" ],
[ 60, "minute"],
[ 1, "second"],
];
let interval = seconds;
let intervalStrings = [];
for (let i = 0; i < intervals.length; i++) {
let divResult = Math.floor(interval / intervals[i][0]);
if (divResult > 0) {
intervalStrings.push(divResult + " " + intervals[i][1] + ((divResult > 1) ? "s" : ""));
interval = interval % intervals[i][0];
if (!longText) {
break;
}
}
}
let intStr = intervalStrings.join(", ");
return intStr + leadingText;
}
The other advantage of using curl is that you also can keep the HTTP way of sending parameters to your script if you need to, by using $_GET
, $_POST
etc like this:
*/5 * * * * curl --request GET 'http://exemple.com/path/check.php?param1=1¶m2=2'
In case anyone wishes to do this with bootstrap, version 4 offers the following:
The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.
Where property is one of:
m - for classes that set margin
p - for classes that set padding
Where sides is one of:
t - for classes that set margin-top or padding-top
b - for classes that set margin-bottom or padding-bottom
l - for classes that set margin-left or padding-left
r - for classes that set margin-right or padding-right
x - for classes that set both *-left and *-right
y - for classes that set both *-top and *-bottom
blank - for classes that set a margin or padding on all 4 sides of the element
Where size is one of:
0 - for classes that eliminate the margin or padding by setting it to 0
1 - (by default) for classes that set the margin or padding to $spacer * .25
2 - (by default) for classes that set the margin or padding to $spacer * .5
3 - (by default) for classes that set the margin or padding to $spacer
4 - (by default) for classes that set the margin or padding to $spacer * 1.5
5 - (by default) for classes that set the margin or padding to $spacer * 3
auto - for classes that set the margin to auto
For example:
.mt-0 {
margin-top: 0 !important;
}
.ml-1 {
margin-left: ($spacer * .25) !important;
}
.px-2 {
padding-left: ($spacer * .5) !important;
padding-right: ($spacer * .5) !important;
}
.p-3 {
padding: $spacer !important;
}

Reason: suppose if some packet(words/statement) is missing we cannot understand the content.It should be reliable.
video streaming:
* **Reason: ***suppose if some packet(frame/sequence) is missing we can understand the content.Because video is collection of frames.For 1 second video there should be 25 frames(image).Even though we can understand some frames are missing due to our imagination skills. Thats why UDP is used for video streaming.

I would not recommend you to start session just to get some unique id. Instead, use such things as uniqid()
because it's intended to return unique id.
However, if you already have session, then, of course, use session_id()
to get your session id - but do not rely on that, because "unique id" isn't same as "session id" in common sense: for example, multiple tabs in most browsers will use same process, thus, use same session identifier in result - and, therefore, different connections will have same id. It's your decision about desired behavior, I've mentioned this just to show the difference between session id and unique id.
J2V8 is best solution of your problem. It's run Nodejs application on jvm(java and android).
J2V8 is Java Bindings for V8, But Node.js integration is available in J2V8 (version 4.4.0)

In case someone wants to get the data frame in a "long format" (leaf values have the same type) without multiindex, you can do this:
pd.DataFrame.from_records(
[
(level1, level2, level3, leaf)
for level1, level2_dict in user_dict.items()
for level2, level3_dict in level2_dict.items()
for level3, leaf in level3_dict.items()
],
columns=['UserId', 'Category', 'Attribute', 'value']
)
UserId Category Attribute value
0 12 Category 1 att_1 1
1 12 Category 1 att_2 whatever
2 12 Category 2 att_1 23
3 12 Category 2 att_2 another
4 15 Category 1 att_1 10
5 15 Category 1 att_2 foo
6 15 Category 2 att_1 30
7 15 Category 2 att_2 bar
(I know the original question probably wants (I.) to have Levels 1 and 2 as multiindex and Level 3 as columns and (II.) asks about other ways than iteration over values in the dict. But I hope this answer is still relevant and useful (I.): to people like me who have tried to find a way to get the nested dict into this shape and google only returns this question and (II.): because other answers involve some iteration as well and I find this approach flexible and easy to read; not sure about performance, though.)
Here you can use following code as a function:
def drawProgressBar(percent, barLen = 20):
sys.stdout.write("\r")
progress = ""
for i in range(barLen):
if i < int(barLen * percent):
progress += "="
else:
progress += " "
sys.stdout.write("[ %s ] %.2f%%" % (progress, percent * 100))
sys.stdout.flush()
With use of .format:
def drawProgressBar(percent, barLen = 20):
# percent float from 0 to 1.
sys.stdout.write("\r")
sys.stdout.write("[{:<{}}] {:.0f}%".format("=" * int(barLen * percent), barLen, percent * 100))
sys.stdout.flush()
A formula for an angle from 0 to 2pi.
There is x=x2-x1 and y=y2-y1.The formula is working for
any value of x and y. For x=y=0 the result is undefined.
f(x,y)=pi()-pi()/2*(1+sign(x))*(1-sign(y^2))
-pi()/4*(2+sign(x))*sign(y)
-sign(x*y)*atan((abs(x)-abs(y))/(abs(x)+abs(y)))

The solution is to stringify the object before calling setItem on the sessionStorage.
var user = {'name':'John'};
sessionStorage.setItem('user', JSON.stringify(user));
var obj = JSON.parse(sessionStorage.user);
Just to add another option to Dónal's answer, you can also still use the good old java.lang.Object.getClass()
method.
In addition to the answers already given it will be quicker if you use OrElse
instead of Or
because the second test is short circuited. This is especially true if you know that one string is more likely than the other in which case place this first:
If strMyString.Contains("Most Likely To Find") OrElse strMyString.Contains("Less Likely to Find") Then

ActiveRecord#where will return an ActiveRecord::Relation object (which will never be nil). Try using .empty? on the relation to test if it will return any records.
First of all you should fix modal HTML structure. Now it's not correct, you don't need class .hide
:
<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body edit-content">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
Then links should point to this modal via data-target
attribute:
<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>
Finally Js part becomes very simple:
$('#edit-modal').on('show.bs.modal', function(e) {
var $modal = $(this),
esseyId = e.relatedTarget.id;
$.ajax({
cache: false,
type: 'POST',
url: 'backend.php',
data: 'EID=' + essayId,
success: function(data) {
$modal.find('.edit-content').html(data);
}
});
})
Another reason that it's a good idea to write both declarations and definitions in header files is for readability. Suppose there's such a template function in Utility.h:
template <class T>
T min(T const& one, T const& theOther);
And in the Utility.cpp:
#include "Utility.h"
template <class T>
T min(T const& one, T const& other)
{
return one < other ? one : other;
}
This requires every T class here to implement the less than operator (<). It will throw a compiler error when you compare two class instances that haven't implemented the "<".
Therefore if you separate the template declaration and definition, you won't be able to only read the header file to see the ins and outs of this template in order to use this API on your own classes, though the compiler will tell you in this case about which operator needs to be overridden.
Acording to the docs:
Note The urllib2 module has been split across several modules in Python 3 named
urllib.request
andurllib.error
. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.
So it appears that it is impossible to do what you want but you can use appropriate python3 functions from urllib.request
.
It formats the string as two uppercase hexadecimal characters.
In more depth, the argument "X2"
is a "format string" that tells the ToString()
method how it should format the string. In this case, "X2" indicates the string should be formatted in Hexadecimal.
byte.ToString()
without any arguments returns the number in its natural decimal representation, with no padding.
Microsoft documents the standard numeric format strings which generally work with all primitive numeric types' ToString()
methods. This same pattern is used for other types as well: for example, standard date/time format strings can be used with DateTime.ToString()
.
While submitting form use reset method on form. The reset() method resets the values of all elements in a form.
$('#form-id')[0].reset();
OR
document.getElementById("form-id").reset();

You can use Phantombuster. Instagram has set some rate limit, so you will have to use either multiple accounts or wait for 15 minutes for the next run.
If we create an EditText dynamically then we have to set the requestFocus() as given below.
EditText editText = new EditText(this);
editText.setWidth(600);
editText.requestFocus();
If already we declared the component in the xml view then we have to find it and we can the focus as given below.
EditText e1=(EditText) findViewById(R.id.editText1);
e1.requestFocus();
It sets only focus to the corresponding EditText component.
If you have a double array named numbers
, you can use:
firstNum = numbers[0];
lastNum = numbers[numbers.length-1];
or with ArrayList
firstNum = numbers.get(0);
lastNum = numbers.get(numbers.size() - 1);
Use case match for early return purpose. It will force you to declare all return branches explicitly, preventing the careless mistake of forgetting to write return somewhere.
I was wondering why I was getting that big warning message on Ubuntu 16.04 (which comes with Git 2.7.4), but not on Arch Linux. The reason is that the warning was removed in Git 2.8 (March 2016):
Across the transition at around Git version 2.0, the user used to get a pretty loud warning when running "git push" without setting push.default configuration variable. We no longer warn because the transition was completed a long time ago.
So you won't see the warning if you have Git 2.8 and later and don't need to set push.default
unless you want to change the default 'simple'
behavior.

You can also make your objects Serializable and use the Bundle's getSerializable and putSerializable methods.
You're effectively scanning the list once to find the min value, then scanning it again to find the index, you can do both in one go:

First of all, there are many, many ways of matching items within a HTML document. Start with this reference to see some of the available selectors/patterns which you can use to apply a style rule to an element(s).

s which are direct descendants of #main
.
#main > div
Match all div
s which are direct or indirect descendants of #main
.
#main div
Match the first div
which is a direct descendant of #sections
.
#main > div:first-child
Match a div
with a specific attribute.
#main > div[foo="bar"]
for i=1,#target do
game.Players.target[i].Character:BreakJoints()
end
Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:
game.Players.target.1.Character:BreakJoints()
Which is completely incorrect.
c = game.Players:GetChildren()
Never use "Players:GetChildren()", it is not guaranteed to return only players.
Instead use:
c = Game.Players:GetPlayers()
if msg:lower()=="me" then
table.insert(people, source)
return people
Here you add the player's name in the list "people", where you in the other places adds the player object.
Fixed code:
local Admins = {"FakeNameHereSoNoStalkers"}
function Kill(Players)
for i,Player in ipairs(Players) do
if Player.Character then
Player.Character:BreakJoints()
end
end
end
function IsAdmin(Player)
for i,AdminName in ipairs(Admins) do
if Player.Name:lower() == AdminName:lower() then return true end
end
return false
end
function GetPlayers(Player,Msg)
local Targets = {}
local Players = Game.Players:GetPlayers()
if Msg:lower() == "me" then
Targets = { Player }
elseif Msg:lower() == "all" then
Targets = Players
elseif Msg:lower() == "others" then
for i,Plr in ipairs(Players) do
if Plr ~= Player then
table.insert(Targets,Plr)
end
end
else
for i,Plr in ipairs(Players) do
if Plr.Name:lower():sub(1,Msg:len()) == Msg then
table.insert(Targets,Plr)
end
end
end
return Targets
end
Game.Players.PlayerAdded:connect(function(Player)
if IsAdmin(Player) then
Player.Chatted:connect(function(Msg)
if Msg:lower():sub(1,6) == ":kill " then
Kill(GetPlayers(Player,Msg:sub(7)))
end
end)

To get only uploaded file Name use this,

The POSIX specification for find says:
-mtime
n
The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), isn

Interestingly, the description of find
does not further specify 'initialization time'. It is probably, though, the time when find
is initialized (run).
In the descriptions, wherever
n
is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a plus ( '+' ) or minus-sign ( '-' ) sign, as follows:
+n

At the given time (2014-09-01 00:53:44 -4:00, where I'm deducing that AST is Atlantic Standard Time, and therefore the time zone offset from UTC is -4:00 in ISO 8601 but +4:00 in ISO 9945 (POSIX), but it doesn't matter all that much):
1409547224 = 2014-09-01 00:53:44 -04:00
1409457540 = 2014-08-30 23:59:00 -04:00
so:
1409547224 - 1409457540 = 89684
89684 / 86400 = 1
Even if the 'seconds since the epoch' values are wrong, the relative values are correct (for some time zone somewhere in the world, they are correct).
The n
value calculated for the 2014-08-30 log file therefore is exactly 1
(the calculation is done with integer arithmetic), and the +1
rejects it because it is strictly a > 1
comparison (and not >= 1
).

C# supports two forms of string literals: regular string literals and verbatim string literals.
A regular string literal consists of zero or more characters enclosed in double quotes, as in "hello", and may include both simple escape sequences (such as \t for the tab character) and hexadecimal and Unicode escape sequences.
A verbatim string literal consists of an @ character followed by a double-quote character, zero or more characters, and a closing double-quote character. A simple example is @"hello". In a verbatim string literal, the characters between the delimiters are interpreted verbatim, the only exception being a quote-escape-sequence. In particular, simple escape sequences and hexadecimal and Unicode escape sequences are not processed in verbatim string literals. A verbatim string literal may span multiple lines.

The other answers posted here will work, but the clearest and most efficient function to use is numpy.any()
:
>>> all_zeros = not np.any(a)
or
>>> all_zeros = not a.any()
numpy.all(a==0)
because it uses less RAM. (It does not require the temporary array created by the a==0
term.)numpy.count_nonzero(a)
because it can return immediately when the first nonzero element has been found.np.any()
no longer uses "short-circuit" logic, so you won't see a speed benefit for small arrays.Referncing from

Constant Pointers
Lets first understand what a constant pointer is. A constant pointer is a pointer that cannot change the address its holding. In other words, we can say that once a constant pointer points to a variable then it cannot point to any other variable.
A constant pointer is declared as follows :
<type of pointer> * const <name of pointer>
An example declaration would look like :
int * const ptr;
Lets take a small code to illustrate these type of pointers :
#include<stdio.h>
int main(void)
{
int var1 = 0, var2 = 0;
int *const ptr = &var1;
ptr = &var2;
printf("%d\n", *ptr);
return 0;
}
In the above example :
Pointer to Constant
As evident from the name, a pointer through which one cannot change the value of variable it points is known as a pointer to constant. These type of pointers can change the address they point to but cannot change the value kept at those address.
A pointer to constant is defined as :
const <type of pointer>* <name of pointer>
An example of definition could be :
const int* ptr;
Lets take a small code to illustrate a pointer to a constant :
#include<stdio.h>
int main(void)
{
int var1 = 0;
const int* ptr = &var1;
*ptr = 1;
printf("%d\n", *ptr);
return 0;
}
In the code above :

Python solution
def subtree(node, relationships):
return {
v: subtree(v, relationships)
for v in [x[0] for x in relationships if x[1] == node]
}
For example:
# (child, parent) pairs where -1 means no parent
flat_tree = [
(1, -1),
(4, 1),
(10, 4),
(11, 4),
(16, 11),
(17, 11),
(24, 17),
(25, 17),
(5, 1),
(8, 5),
(9, 5),
(7, 9),
(12, 9),
(22, 12),
(23, 12),
(2, 23),
(26, 23),
(27, 23),
(20, 9),
(21, 9)
]
subtree(-1, flat_tree)
Produces:
{
"1": {
"4": {
"10": {},
"11": {
"16": {},
"17": {
"24": {},
"25": {}
}
}
},
"5": {
"8": {},
"9": {
"20": {},
"12": {
"22": {},
"23": {
"2": {},
"27": {},
"26": {}
}
},
"21": {},
"7": {}
}
}
}
}
if the current thread is killed and you use Thread.Sleep
and it is executing then you might get a ThreadAbortException
.
With Task.Delay
you can always provide a cancellation token and gracefully kill it. Thats one reason I would choose Task.Delay
. see http://social.technet.microsoft.com/wiki/contents/articles/21177.visual-c-thread-sleep-vs-task-delay.aspx
I also agree efficiency is not paramount in this case.
Easiest way is:
First create a label named label1. Go to label1's events > mouse events > Label1_Mouse Move and write these:
if (e.Button == MouseButtons.Left){
Left += e.X;
Top += e.Y;`
}
Be careful with nulls and checking for inequality in sql server.
For example
select * from foo where bla <> 'something'
will NOT return records where bla is null. Even though logically it should.
So the right way to check would be
select * from foo where isnull(bla,'') <> 'something'
Which of course people often forget and then get weird bugs.
I am working on a project for a print-shop and had some problems due to uploading images to the server that came from an HTML5 canvas
element. I was struggling for at least an hour and I did not get it to save the image correctly on my server.
Once I set the
contentType
option of my jQuery ajax call to application/x-www-form-urlencoded
everything went the right way and the base64-encoded data was interpreted correctly and successfully saved as an image.
Maybe that helps someone!
I just got this error and i came to know that it is about the local variable alias
at the end of the stored procedure i had like
select @localvariable1,@localvariable2
it was working fine in sql but when i ran this in ssrs it was always throwing error but after I gave alias it is fixed
select @localvariable1 as A,@localvariable2 as B
You can get the maximum like this:
>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]]
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]].max(axis=1)
0 1
1 8
2 3
and so:
>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
If you know that "A" and "B" are the only columns, you could even get away with
>>> df["C"] = df.max(axis=1)
And you could use .apply(max, axis=1)
too, I guess.
In my case, heredoc caused the issue. There is no problem with PHP version 7.3 up. Howerver, it error with PHP 7.0.33 if you use heredoc with space.
My example code
$rexpenditure = <<<Expenditure
<tr>
<td>$row->payment_referencenumber</td>
<td>$row->payment_requestdate</td>
<td>$row->payment_description</td>
<td>$row->payment_fundingsource</td>
<td>$row->payment_agencyulo</td>
<td>$row->payment_agencyproject</td>
<td>$$row->payment_disbustment</td>
<td>$row->payment_payeename</td>
<td>$row->payment_processpayment</td>
</tr>
Expenditure;
It will error if there is a space on PHP 7.0.33.
To get the first and the last day of the year, one can use the CONCAT
function. The resulting value may be cast to any type.
CONCAT(YEAR(Getdate()),'-01-01') FirstOfYear,
CONCAT(YEAR(GETDATE()),'-12-31') LastOfYear
If you're using #
as an operator, consider defining a new operator for it:
\newcommand{\pound}{\operatornamewithlimits{\#}}
You can then write things like \pound_{n = 1}^N
and get:
Every time you call e.nextElement()
you take the next object from the iterator. You have to check e.hasMoreElement()
between each call.
Example:
while(e.hasMoreElements()){
String param = e.nextElement();
System.out.println(param);
}
You need to preserve the index of array members better as they are unique Here is a working code with few changes:
#include<stdio.h>
int main()
{
int a[10],n;
int largest1,largest2,i;
printf("enter number of elements you want in array");
scanf("%d",&n);
printf("enter elements");
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
largest1=0;
for(i=0;i<n;i++)
{
if(a[i]>a[largest1])
{
largest1=i;
}
}
if(largest1!=0) // this condition to select another index than the largest
largest2=0;
else
largest2=n-1;
for(i=0;i<n && i != largest1 ;i++)
{
if(a[i]>a[largest2])
largest2=i;
}
printf("First and second largest number is %d and %d ",a[largest1],a[largest2]);
}
Note that when the array is of size 1 values will be the same.
To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.
After a lot of research, I was able to come up with this. This has more special characters
validatePassword(password) {
const re = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*()+=-\?;,./{}|\":<>\[\]\\\' ~_]).{8,}/
return re.test(password);
}
I've recently had to use eval
to force multiple brace expansions to be evaluated in the order I needed. Bash does multiple brace expansions from left to right, so
xargs -I_ cat _/{11..15}/{8..5}.jpg
expands to
xargs -I_ cat _/11/8.jpg _/11/7.jpg _/11/6.jpg _/11/5.jpg _/12/8.jpg _/12/7.jpg _/12/6.jpg _/12/5.jpg _/13/8.jpg _/13/7.jpg _/13/6.jpg _/13/5.jpg _/14/8.jpg _/14/7.jpg _/14/6.jpg _/14/5.jpg _/15/8.jpg _/15/7.jpg _/15/6.jpg _/15/5.jpg
but I needed the second brace expansion done first, yielding
xargs -I_ cat _/11/8.jpg _/12/8.jpg _/13/8.jpg _/14/8.jpg _/15/8.jpg _/11/7.jpg _/12/7.jpg _/13/7.jpg _/14/7.jpg _/15/7.jpg _/11/6.jpg _/12/6.jpg _/13/6.jpg _/14/6.jpg _/15/6.jpg _/11/5.jpg _/12/5.jpg _/13/5.jpg _/14/5.jpg _/15/5.jpg
The best I could come up with to do that was
xargs -I_ cat $(eval echo _/'{11..15}'/{8..5}.jpg)
This works because the single quotes protect the first set of braces from expansion during the parsing of the eval
command line, leaving them to be expanded by the subshell invoked by eval
.
There may be some cunning scheme involving nested brace expansions that allows this to happen in one step, but if there is I'm too old and stupid to see it.
From Google OAuth2.0 for Client documentation,
It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:
char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);
Without the fflush()
, if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar()
peeks the "a", but the "\n" remains in the buffer, so the next fgets()
will find it and return an empty string without even waiting for user input.
However, note that this use of fflush()
is unportable. I've tested right now on a Linux machine, and it does not work, for example.
Calling an external command in Python
A simple way to call an external command is using os.system(...)
. And this function returns the exit value of the command. But the drawback is we won't get stdout and stderr.
ret = os.system('some_cmd.sh')
if ret != 0 :
print 'some_cmd.sh execution returned failure'
Calling an external command in Python in background
subprocess.Popen
provides more flexibility for running an external command rather than using os.system
. We can start a command in the background and wait for it to finish. And after that we can get the stdout and stderr.
proc = subprocess.Popen(["./some_cmd.sh"], stdout=subprocess.PIPE)
print 'waiting for ' + str(proc.pid)
proc.wait()
print 'some_cmd.sh execution finished'
(out, err) = proc.communicate()
print 'some_cmd.sh output : ' + out
Calling a long running external command in Python in the background and stop after some time
We can even start a long running process in the background using subprocess.Popen
and kill it after sometime once its task is done.
proc = subprocess.Popen(["./some_long_run_cmd.sh"], stdout=subprocess.PIPE)
# Do something else
# Now some_long_run_cmd.sh exeuction is no longer needed, so kill it
os.system('kill -15 ' + str(proc.pid))
print 'Output : ' proc.communicate()[0]
You can set the attribute translatable="false" on the definition like this:
<string name="account_setup_imap" translatable="false">IMAP</string>
For more information: http://tools.android.com/recent/non-translatablestrings
For set value when your control is FormGroup can use this example
this.clientForm.controls['location'].setValue({
latitude: position.coords.latitude,
longitude: position.coords.longitude
});
With the latest aws-cli python command line tools, to recursively delete all the files under a folder in a bucket is just:
aws s3 rm --recursive s3://your_bucket_name/foo/
Or delete everything under the bucket:
aws s3 rm --recursive s3://your_bucket_name
If what you want is to actually delete the bucket, there is one-step shortcut:
aws s3 rb --force s3://your_bucket_name
which will remove the contents in that bucket recursively then delete the bucket.
Note: the s3://
protocol prefix is required for these commands to work
My solution is similar to ATom's one, but easier to implement. You don't need to create a class that shadows FirebaseMessagingService completely, you can just override the method that receives the Intent (which is public, at least in version 9.6.1) and take the information to be displayed from the extras. The "hacky" part is that the method name is indeed obfuscated and is gonna change every time you update the Firebase sdk to a new version, but you can look it up quickly by inspecting FirebaseMessagingService with Android Studio and looking for a public method that takes an Intent as the only parameter. In version 9.6.1 it's called zzm. Here's how my service looks like:
public class MyNotificationService extends FirebaseMessagingService {
public void onMessageReceived(RemoteMessage remoteMessage) {
// do nothing
}
@Override
public void zzm(Intent intent) {
Intent launchIntent = new Intent(this, SplashScreenActivity.class);
launchIntent.setAction(Intent.ACTION_MAIN);
launchIntent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* R equest code */, launchIntent,
PendingIntent.FLAG_ONE_SHOT);
Bitmap rawBitmap = BitmapFactory.decodeResource(getResources(),
R.mipmap.ic_launcher);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_notification)
.setLargeIcon(rawBitmap)
.setContentTitle(intent.getStringExtra("gcm.notification.title"))
.setContentText(intent.getStringExtra("gcm.notification.body"))
.setAutoCancel(true)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

1) in a query window in SQL Server Management Studio, run the command:
SET SHOWPLAN_ALL ON
2) run your slow query
3) your query will not run, but the execution plan will be returned. store this output
4) run your fast version of the query
5) your query will not run, but the execution plan will be returned. store this output
6) compare the slow query version output to the fast query version output.
7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

You were just missing an image tag to change the "src" attribute of:
<html>
<body>
<form>

<input type="button" onclick="document.getElementById('img1').src = 'http://webpage.com/images/' + document.getElementById('imagename').value +'.png'" value="GO">

<img id="img1" src="defaultimage.png" />
</form>

You can do it in single line, seperate each digits than add them together :
var may = 12987;
var sep = (""+may).split("").map(n=>+n).reduce((a,b)=>a+b);
Generally you should also override hashCode()
each time you override equals()
, even if just for the performance boost. HashCode()
decides which 'bucket' your object gets sorted into when doing a comparison, so any two objects which equal()
evaluates to true should return the same hashCode
value()
. I cannot remember the default behavior of hashCode()
(if it returns 0 then your code should work but slowly, but if it returns the address then your code will fail). I do remember a bunch of times when my code failed because I forgot to override hashCode()
though. :)
Here is one way to calculate log return using .shift()
. And the result is similar to but not the same as the gross return calculated by pct_change()
. Can you upload a copy of your sample data (dropbox share link) to reproduce the inconsistency you saw?
import pandas as pd
import numpy as np
np.random.seed(0)
df = pd.DataFrame(100 + np.random.randn(100).cumsum(), columns=['price'])
df['pct_change'] = df.price.pct_change()
df['log_ret'] = np.log(df.price) - np.log(df.price.shift(1))

In my case even after deleting the workspace and reimport doesn't work. Because all the files are Corrupted. so have utilized my existing backup data, extracted it & reimported into workspace then it started working fine.
If your project is on GitHub, you now (April 2013) have Pulse (see "Get up to speed with Pulse"):
It is more limited, and won't display all the stats you might need, but is readily available for any GitHub project.
Pulse is a great way to discover recent activity on projects.
Pulse will show you who has been actively committing and what has changed in a project's default branch:
You can find the link to the left of the nav bar.
Note that there isn't (yet) an API to extract that information.

Your data.json
should look like this:
{
"maps":[
{"id":"blabla","iscategorical":"0"},
{"id":"blabla","iscategorical":"0"}
],
"masks":
{"id":"valore"},
"om_points":"value",
"parameters":
{"id":"valore"}
}
Your code should be:
import json
from pprint import pprint
with open('data.json') as data_file:
data = json.load(data_file)
pprint(data)
Note that this only works in Python 2.6 and up, as it depends upon the with
-statement. In Python 2.5 use from __future__ import with_statement
, in Python <= 2.4, see Justin Peel's answer, which this answer is based upon.
You can now also access single values like this:
data["maps"][0]["id"] # will return 'blabla'
data["masks"]["id"] # will return 'valore'
data["om_points"] # will return 'value'

We use log4net on our web applications.
It's ability to customize logging at run-time by changing the XML configuration file is very handy when an application is malfunctioning at run-time and you need to see more information.
It also allows you to target specific classes or attributes to log under. This is very handy when you have an idea where the error is occurring. A classic example is NHibernate where you want to see just the SQL going to the database.
Edit:
We write all events to a database and the Trace system. The event log we use for errors or exceptions. We log most events to a database so that we can create custom reports and let the users view the log if they want to right from the application.
Restarting the machine worked for me but not every time.

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:
bar <- foo[foo[ ,1] == "there", ]
This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).
This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:
foo[foo[ ,c(1:N)], ]
Or specific columns, as you would expect.
foo[foo[ ,c(1,5,9)], ]
You can also use window.setInterval() to run some code repeatedly at a regular interval.
I done it, below code is working for me....
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.hello_world, container, false);

newPage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(), HomeActivity.class);
startActivity(intent);
}
});
return v;
}
and Please make sure that your destination activity should be register in Manifest.xml file,
but in my case all tabs are not shown in HomeActivity, is any solution for that ?
@Adrian Cornish's answer is correct. However, there is another caveat to dropping an existing primary key. If that primary key is being used as a foreign key by another table you will get an error when trying to drop it. In some versions of mysql the error message there was malformed (as of 5.5.17, this error message is still
alter table parent drop column id;
ERROR 1025 (HY000): Error on rename of
'./test/#sql-a04_b' to './test/parent' (errno: 150).
If you want to drop a primary key that's being referenced by another table, you will have to drop the foreign key in that other table first. You can recreate that foreign key if you still want it after you recreate the primary key.
Also, when using composite keys, order is important. These
1) ALTER TABLE provider ADD PRIMARY KEY(person,place,thing);
and
2) ALTER TABLE provider ADD PRIMARY KEY(person,thing,place);
are not the the same thing. They both enforce uniqueness on that set of three fields, however from an indexing standpoint there is a difference. The fields are indexed from left to right. For example, consider the following queries:
A) SELECT person, place, thing FROM provider WHERE person = 'foo' AND thing = 'bar';
B) SELECT person, place, thing FROM provider WHERE person = 'foo' AND place = 'baz';
C) SELECT person, place, thing FROM provider WHERE person = 'foo' AND place = 'baz' AND thing = 'bar';
D) SELECT person, place, thing FROM provider WHERE place = 'baz' AND thing = 'bar';
B can use the primary key index in ALTER statement 1
A can use the primary key index in ALTER statement 2
C can use either index
D can't use either index
A uses the first two fields in index 2 as a partial index. A can't use index 1 because it doesn't know the intermediate place portion of the index. It might still be able to use a partial index on just person though.
D can't use either index because it doesn't know person.
See the mysql docs here for more information.

I usually use a plain old VARCHAR filtering for an IPAddress works fine.
If you want to filter on ranges of IP address I'd break it into four integers.
I had the same issue just add this function to the open dialog options and it worked sharm
open: function(){
var closeBtn = $('.ui-dialog-titlebar-close');
closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
},
and on close event you need to remove that
close: function () {
var closeBtn = $('.ui-dialog-titlebar-close');
closeBtn.html('');}
Complete example
<div id="deleteDialog" title="Confirm Delete">
Can you confirm you want to delete this event?
</div>
$("#deleteDialog").dialog({
width: 400, height: 200,
modal: true,
open: function () {
var closeBtn = $('.ui-dialog-titlebar-close');
closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>');
},
close: function () {
var closeBtn = $('.ui-dialog-titlebar-close');
closeBtn.html('');
},
buttons: {
"Confirm": function () {
calendar.fullCalendar('removeEvents', event._id);
$(this).dialog("close");
},
"Cancel": function () {
$(this).dialog("close");
}
}
});
$("#dialog").dialog("open");
My work uses Winnovative's PDF generator (We've used it mainly to convert HTML to PDF, but you can generate it other ways as well)
I'm working with .NET 4.5 and couldn't get this working... I was using WPF Custom Control Library. This worked for me in the end...
<ResourceDictionary Source="/MyAssembly;component/mytheme.xaml" />

I have received this error in react.js. If you have a button in the form that you want to act like a button and not submit the form, you must give it type="button". Otherwise it tries to submit the form. I believe vaskort answered this with some documentation you can check out.
One of the comments here used gs on Windows. I had some success with that on Linux/OSX too, with the following syntax:
gs \
-q \
-dNODISPLAY \
-dSAFER \
-dDELAYBIND \
-dWRITESYSTEMDICT \
-dSIMPLE \
-f ps2ascii.ps \
"${input}" \
-dQUIET \
-c quit
I used dSIMPLE
instead of dCOMPLEX
because the latter outputs 1 character per line.
Another solution for typescript user:
import Vue from "vue";
import Component from "vue-class-component";
@Component({
beforeRouteLeave(to, from, next) {
// incase if you want to access `this`
// const self = this as any;
next();
}
})
export default class ComponentName extends Vue {}
This will help exactly what you want
replace dt - your datetime c - call field astro_transit1 - your table 300 refer 5 min so add 300 each time for time gap increase
SELECT FROM_UNIXTIME( 300 * ROUND( UNIX_TIMESTAMP( r.dt ) /300 ) ) AS 5datetime, (
SELECT r.c
FROM astro_transit1 ra
WHERE ra.dt = r.dt
ORDER BY ra.dt DESC
LIMIT 1
) AS first_val FROM astro_transit1 r GROUP BY UNIX_TIMESTAMP( r.dt )
DIV 300
LIMIT 0 , 30
App_Data is essentially a storage point for file-based data stores (as opposed to a SQL server database store for example). Some simple sites make use of it for content stored as XML for example, typically where hosting charges for a DB are expensive.
One way to track import error is step by step trying to run python on each of imported files to track down bad one.
you get something like:
python ./main.py
ImportError: cannot import name A
then you launch:
python ./modules/a.py
ImportError: cannot import name B
then you launch:
python ./modules/b.py
ImportError: cannot import name C (some NON-Existing module or some other error)
You can use either lower or upper function on both sides of the where condition
That's the platform toolset for VS2015. You uninstalled it, therefore it is no longer available.
To change your Platform Toolset:
I just tried the same in EF6 (code first entity rename). I simply renamed the class and added a migration using the package manager console and voila, a migration using RenameTable(...) was automatically generated for me. I have to admit that I made sure the only change to the entity was renaming it so no new columns or renamed columns so I cannot be certain if this is an EF6 thing or just that EF was (always) able to detect such simple migrations.
Did you try
:set encoding=utf-8
:set fileencoding=utf-8
?
Memory mapping has a potential for a huge speed advantage compared to traditional IO. It lets the operating system read the data from the source file as the pages in the memory mapped file are touched. This works by creating faulting pages, which the OS detects and then the OS loads the corresponding data from the file automatically.
This works the same way as the paging mechanism and is usually optimized for high speed I/O by reading data on system page boundaries and sizes (usually 4K) - a size for which most file system caches are optimized to.
Probably
git --rebase --autostash
would help
Good question. Similar to the observation you have about examples 1 and 4 (or should I say 1 & 4 :) ) over logical and
bitwise &
operators, I experienced on sum
operator. The numpy sum
and py sum
behave differently as well. For example:
Suppose "mat" is a numpy 5x5 2d array such as:
array([[ 1, 2, 3, 4, 5],
[ 6, 7, 8, 9, 10],
[11, 12, 13, 14, 15],
[16, 17, 18, 19, 20],
[21, 22, 23, 24, 25]])
Then numpy.sum(mat) gives total sum of the entire matrix. Whereas the built-in sum from Python such as sum(mat) totals along the axis only. See below:
np.sum(mat) ## --> gives 325
sum(mat) ## --> gives array([55, 60, 65, 70, 75])
You can use the sleep()
function in the time
module. It can take a float argument for sub-second resolution.
from time import sleep
sleep(0.1) # Time in seconds
this is what I use for a cross-platform code:
#ifdef _WIN32
#include <Windows.h>
#else
#include <unistd.h>
#endif
int main()
{
pollingDelay = 100
//do stuff
//sleep:
#ifdef _WIN32
Sleep(pollingDelay);
#else
usleep(pollingDelay*1000); /* sleep for 100 milliSeconds */
#endif
//do stuff again
return 0;
}
No one mentioned liriliri/eruda which adds its own debugging tools meant for mobile websites/apps
Adding this to your page:
<script src="//cdn.jsdelivr.net/npm/eruda"></script>
<script>eruda.init();</script>
Will add a floating icon to your page which opens the console.
Use:
import color
class Color(color.Color):
...
If this were Python 2.x, you would also want to derive color.Color
from object
, to make it a new-style class:
class Color(object):
...
This is not necessary in Python 3.x.
I assume X
and Y
are arrays? If so, there's a very simple way to do this:
x = [1, 1, 2, 4]
y = [1, 2, 2, 2]
# intersection
x & y # => [1, 2]
# union
x | y # => [1, 2, 4]
# difference
x - y # => [4]
It looks like ng-attr
is a new directive in AngularJS 1.1.4 that you can possibly use in this case.
<!-- example -->
<a ng-attr-title="{{product.shortDesc}}"></a>
However, if you stay with 1.0.7, you can probably write a custom directive to mirror the effect.
On windows use the name of the table in quotes:
TABLE "user";
or SELECT * FROM "user";
No, enums are supposed to be a complete static enumeration.
At compile time, you might want to generate your enum .java file from another source file of some sort. You could even create a .class file like this.
In some cases you might want a set of standard values but allow extension. The usual way to do this is have an interface
for the interface and an enum
that implements that interface
for the standard values. Of course, you lose the ability to switch
when you only have a reference to the interface
.
This works for me:
<body>
<form>
[...]
<div style="position:absolute; top:60px; left:10px; width:500px; height:500px;">
<canvas id="cv_values"></canvas>
<script type="text/javascript">
var indicatedValueData = {
labels: ["1", "2", "3"],
datasets: [
{
[...]
};
var cv_values = document.getElementById("cv_values").getContext("2d");
var myChart = new Chart(cv_values, { type: "line", data: indicatedValueData });
</script>
</div>
</form>
</body>
The essential fact is that we have to set the size of the canvas in the div-tag.
If you can use only Java 8 or lower:
1) if you don't have spring-data
the best way so far is:
opt.<Runnable>map(param -> () -> System.out.println(param))
.orElse(() -> System.out.println("no-param-specified"))
.run();
Now I know it's not so readable and even hard to understand for someone, but looks fine for me personally and I don't see another nice fluent way for this case.
2) if you're lucky enough and you can use spring-data
the best way is
Optionals#ifPresentOrElse:
Optionals.ifPresentOrElse(opt, System.out::println,
() -> System.out.println("no-param-specified"));
If you can use Java 9, you should definitely go with:
opt.ifPresentOrElse(System.out::println,
() -> System.out.println("no-param-specified"));
in the header:
enum EFooOptions
{
FooOptionsA = 0, EFooOptionsMin = 0,
FooOptionsB,
FooOptionsC,
FooOptionsD
EFooOptionsMax
};
extern const wchar* FOO_OPTIONS[EFooOptionsMax];
in the .cpp file:
const wchar* FOO_OPTIONS[] = {
L"One",
L"Two",
L"Three",
L"Four"
};
Caveat: Don't handle bad array index. :) But you can easily add a function to verify the enum before getting the string from the array.
You can simply add onended="myFunction()"
to your video tag.
<video onended="myFunction()">
...
Your browser does not support the video tag.
</video>
<script type='text/javascript'>
function myFunction(){
console.log("The End.")
}
</script>
npm install node-v8-clone
Fastest cloner, it open native clone method from node.js
var clone = require('node-v8-clone').clone;
var newObj = clone(obj, true); //true - deep recursive clone
I think what you are looking for is
Request.QueryString["QueryStringName"]
and you can access it on views by adding @
now look at my example,,, I generated a Url with QueryString
var listURL = '@Url.RouteUrl(new { controller = "Sector", action = "List" , name = Request.QueryString["name"]})';
the listURL value is /Sector/List?name=value'
and when queryString
is empty
listURL value is /Sector/List
Another option if you are using Guava Collections is Ints.indexOf
// Perfect storm:
final int needle = 42;
final int[] haystack = [1, 2, 3, 42];
// Spoiler alert: index == 3
final int index = Ints.indexOf(haystack, needle);
This is a great choice when space, time and code reuse are at a premium. It is also very terse.
You have to create two triggers, but you can move the common code into a procedure and have them both call the procedure.
Create an interface IFooable
, then make your A
and B
classes to implement a common method, which in turn calls the corresponding method you want:
interface IFooable
{
public void Foo();
}
class A : IFooable
{
//other methods ...
public void Foo()
{
this.Hop();
}
}
class B : IFooable
{
//other methods ...
public void Foo()
{
this.Skip();
}
}
class ProcessingClass
{
public void Foo(object o)
{
if (o == null)
throw new NullRefferenceException("Null reference", "o");
IFooable f = o as IFooable;
if (f != null)
{
f.Foo();
}
else
{
throw new ArgumentException("Unexpected type: " + o.GetType());
}
}
}
Note, that it's better to use as
instead first checking with is
and then casting, as that way you make 2 casts, so it's more expensive.
I was getting similar problem for other reason (url pattern test-response
not added in csrf token)
I resolved it by allowing my URL pattern in following property in config/local.properties
:
csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$
modified to
csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$,/[^/]+(/[^?])+(test-response)$
Why not loop through the inputs and then add onclick handlers to each?
You don't have to do this in HTML, but you can add a handler to each button like:
button.onclick = function(){ DoStuff(this.value); return false; } // return false; so that form does not submit
Then your function could "do stuff" according to whichever value you passed:
function DoStuff(val) {
if( val === "Val 1" ) {
// Do some stuff
}
// Do other stuff
}
VBA subs are no macros. A VBA sub can be a macro, but it is not a must.
The term "macro" is only used for recorded user actions. from these actions a code is generated and stored in a sub. This code is simple and do not provide powerful structures like loops, for example Do .. until, for .. next, while.. do, and others.
The more elegant way is, to design and write your own VBA code without using the macro features!
VBA is a object based and event oriented language. Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.
If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx.exe".
In VBA you have nothing like this, but you have a XLSM file wich is started by Excel. You can attach some code to the Workbook_Open event. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets.
It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.
In the object based model you have objects, that have events and methods. methods are action you can do with a object. events are things that can happen to an object. An objects can contain another objects, and so on. You can create new objects, like sheets or charts.

I know that this is not the C#, but in the framework (VB.NET) there is already such a function
Dim str As String = "UPPERlower"
Dim b As Boolean = InStr(str, "UpperLower")
C# variant:
string myString = "Hello World";
bool contains = Microsoft.VisualBasic.Strings.InStr(myString, "world");
This does the job.
Returns an array of nodes containing text
.
function get_nodes_containing_text(selector, text) {
const elements = [...document.querySelectorAll(selector)];
return elements.filter(
(element) =>
element.childNodes[0]
&& element.childNodes[0].nodeValue
&& RegExp(text, "u").test(element.childNodes[0].nodeValue.trim())
);
}
The issue is you're creating a List using Arrays.asList() method with fixed Length meaning that
Since the returned List is a fixed-size List, we can’t add/remove elements.
See the below block of code that I am using
This iteration will give an Exception Since it is an iteration list Created by asList() so remove and add are not possible, it is a fixed array
List<String> words = Arrays.asList("pen", "pencil", "sky", "blue", "sky", "dog");
for (String word : words) {
if ("sky".equals(word)) {
words.remove(word);
}
}
This will work fine since we are taking a new ArrayList we can perform modifications while iterating
List<String> words1 = new ArrayList<String>(Arrays.asList("pen", "pencil", "sky", "blue", "sky", "dog"));
for (String word : words) {
if ("sky".equals(word)) {
words.remove(word);
}
}
In objectMapper we have writeValueAsString() which accepts object as parameter. We can pass object list as parameter get the string back.
List<Apartment> aptList = new ArrayList<Apartment>();
Apartment aptmt = null;
for(int i=0;i<5;i++){
aptmt= new Apartment();
aptmt.setAptName("Apartment Name : ArrowHead Ranch");
aptmt.setAptNum("3153"+i);
aptmt.setPhase((i+1));
aptmt.setFloorLevel(i+2);
aptList.add(aptmt);
}
mapper.writeValueAsString(aptList)
This is the cleanest solution for me
import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
export class MyComponent {
constructor(
private route: ActivatedRoute
) {}
ngOnInit() {
const firstParam: string = this.route.snapshot.queryParamMap.get('firstParamKey');
const secondParam: string = this.route.snapshot.queryParamMap.get('secondParamKey');
}
}
It worked for me just by adding serverTimeZone=UTC on application.properties.
spring.datasource.url=jdbc:mysql://localhost/db?serverTimezone=UTC
Another one for those only concerned with truthy elements
ary.find(Boolean);
