Note: This solution uses Typescript (you can use the vanilla JS which TS compiles to if needed)
class asd {
def = new class {
ads= 'asd';
qwe= this.ads + '123';
};
// this method is just to check/test this solution
check(){
console.log(this.def.qwe);
}
}
// these two lines are just to check
let instance = new asd();
instance.check();
Here were using class expressions to get the nested object literal interface we'd want. This is the next best thing IMHO to being able to reference the properties of an object during creation.
Main thing to note is while using this solution, you have exact same interface as you'd have had from an object literal. And the syntax is pretty close to an object literal itself (vs using a function, etc).
class asd {
def = new class {
ads= 'asd';
qwe= this.ads + '123';
};
var asd = {
def : {
ads:'asd',
qwe: this.ads + '123';, //ILLEGAL CODE; just to show ideal scenario
}
}
Here in this class, you can combine multiple relative path among themselves, which is not possible with an object literal.
class CONSTANT {
static readonly PATH = new class {
/** private visibility because these relative paths don't make sense for direct access, they're only useful to path class
*
*/
private readonly RELATIVE = new class {
readonly AFTER_EFFECTS_TEMPLATE_BINARY_VERSION: fs.PathLike = '\\assets\\aep-template\\src\\video-template.aep';
readonly AFTER_EFFECTS_TEMPLATE_XML_VERSION: fs.PathLike = '\\assets\\aep-template\\intermediates\\video-template.aepx';
readonly RELATIVE_PATH_TO_AFTER_EFFECTS: fs.PathLike = '\\Adobe\\Adobe After Effects CC 2018\\Support Files\\AfterFX.exe';
readonly OUTPUT_DIRECTORY_NAME: fs.PathLike = '\\output';
readonly INPUT_DIRECTORY_NAME: fs.PathLike = '\\input';
readonly ASSETS_DIRECTORY_NAME: fs.PathLike = '\\assets';
};
}
}
Since its a question of the past but the problem of present. Would suggest one more solution: Just pass the key and values to the function and you will get a map object.
var map = {};
function addValueToMap(key, value) {
map[key] = map[key] || [];
map[key].push(value);
}
You can also try like this:
let array1 = [{_x000D_
"description": "THURSDAY",_x000D_
"count": "1",_x000D_
"date": "2019-12-05"_x000D_
},_x000D_
{_x000D_
"description": "WEDNESDAY",_x000D_
"count": "0",_x000D_
"date": "2019-12-04"_x000D_
}]_x000D_
let res = array1.map((value, index) => {_x000D_
return { [value.description]: { count: value.count, date: value.date } }_x000D_
})_x000D_
console.log(res);
_x000D_
If you are using jQuery you can use the extend function to add new items.
var olddata = {"fruit":{"apples":10,"pears":21}};
var newdata = {};
newdata['vegetables'] = {"carrots": 2, "potatoes" : 5};
$.extend(true, olddata, newdata);
This will generate:
{"fruit":{"apples":10,"pears":21}, "vegetables":{"carrots":2,"potatoes":5}};
You need to use brackets if the property names has special characters:
var foo = {
"Hello, world!": true,
}
foo["Hello, world!"] = false;
Other than that, I suppose it's just a matter of taste. IMHO, the dot notation is shorter and it makes it more obvious that it's a property rather than an array element (although of course JavaScript does not have associative arrays anyway).
You can do something like that in ES6.
new Array(10).fill().map((e,i) => {
return {idx: i}
});
JavaScript's object literal syntax, which is typically used to instantiate objects (seriously, no one uses new Object
or new Array
), is as follows:
var obj = {
'key': 'value',
'another key': 'another value',
anUnquotedKey: 'more value!'
};
For arrays it's:
var arr = [
'value',
'another value',
'even more values'
];
If you need objects within objects, that's fine too:
var obj = {
'subObject': {
'key': 'value'
},
'another object': {
'some key': 'some value',
'another key': 'another value',
'an array': [ 'this', 'is', 'ok', 'as', 'well' ]
}
}
This convenient method of being able to instantiate static data is what led to the JSON data format.
JSON is a little more picky, keys must be enclosed in double-quotes, as well as string values:
{"foo":"bar", "keyWithIntegerValue":123}
From what the other answers have proposed, I believe this might help:
var object = ips[ipId];
var name = "Joe";
var anothername = "Fred";
var value = "Thingy";
var anothervalue = "Fingy";
object[name] = value;
object[anothername] = anothervalue;
However, this is not tested, just an assumption based on the constant repetition of:
object["string"] = value;
//object = {string: value}
Range with step ES6, that works similar to python list(range(start, stop[, step]))
:
const range = (start, stop, step = 1) => {
return [...Array(stop - start).keys()]
.filter(i => !(i % Math.round(step)))
.map(v => start + v)
}
Examples:
range(0, 8) // [0, 1, 2, 3, 4, 5, 6, 7]
range(4, 9) // [4, 5, 6, 7, 8]
range(4, 9, 2) // [4, 6, 8]
range(4, 9, 3) // [4, 7]
On Windows, if you have already have the virtualenvironment eg. 'myvenv' located within the project root, you can activate it from the terminal as below:
.\myvenv\Scripts\activate
Calling the activate from the virtualenv you desire to activate, activates the virtualenv.
You know it is activated when you see the change:
C:\Projects\Trunk\MyProject>
to
(myvenv)C:\Projects\Trunk\MyProject>
If you want to overwrite the element with key 0
function[0] = 42;
Otherwise:
function.insert(std::make_pair(0, 42));
A JMS topic is the type of destination in a 1-to-many model of distribution. The same published message is received by all consuming subscribers. You can also call this the 'broadcast' model. You can think of a topic as the equivalent of a Subject in an Observer design pattern for distributed computing. Some JMS providers efficiently choose to implement this as UDP instead of TCP. For topic's the message delivery is 'fire-and-forget' - if no one listens, the message just disappears. If that's not what you want, you can use 'durable subscriptions'.
A JMS queue is a 1-to-1 destination of messages. The message is received by only one of the consuming receivers (please note: consistently using subscribers for 'topic client's and receivers for queue client's avoids confusion). Messages sent to a queue are stored on disk or memory until someone picks it up or it expires. So queues (and durable subscriptions) need some active storage management, you need to think about slow consumers.
In most environments, I would argue, topics are the better choice because you can always add additional components without having to change the architecture. Added components could be monitoring, logging, analytics, etc. You never know at the beginning of the project what the requirements will be like in 1 year, 5 years, 10 years. Change is inevitable, embrace it :-)
I have tested the suggested solutions, they should all work:
select * from dual where (105 = to_number('105'))
=> delivers one dummy row
select * from dual where (10 = to_number('105'))
=> empty result
select * from dual where ('105' = to_char(105))
=> delivers one dummy row
select * from dual where ('105' = to_char(10))
=> empty result
A better alternative is to use weakref.finalize. See the examples at Finalizer Objects and Comparing finalizers with __del__() methods.
here is the solution
Put your html and css in your /assets/ folder, then load the html file like so:
WebView wv = new WebView(this);
wv.loadUrl("file:///android_asset/yourHtml.html");
then in your html you can reference your css in the usual way
<link rel="stylesheet" type="text/css" href="main.css" />
You can try delete project via Google Cloud Platform https://console.cloud.google.com/iam-admin/projects
Select required project and click DELETE PROJECT. The project will be completely deleted after 7 days
You could use:
$('#btnForm').click(function(){
$.fancybox({
'content' : $("#divForm").html()
});
};
You can also use array_column()
. It's available from PHP 5.5: php.net/manual/en/function.array-column.php
It returns the values from a single column of the array, identified by the column_key. Optionally, you may provide an index_key to index the values in the returned array by the values from the index_key column in the input array.
print_r(array_column($myarray, 'email'));
On http://www.google.com/earth/media/licensing.html there is a "Mobile" section containing :
Similar to our online terms, if you use our APIs or a mobile device’s native Google Maps implementation (such as on an Android-powered phone or iPhone), no special permission is required, but you must always keep the Google name visible. Offline caching of our content is never allowed.
There were a number of suggestions from an earlier similar question "Best way to test for existing string against a large list of comparables".
Regex might be sufficient for your requirement. The expression would be a concatenation of all the candidate substrings, with an OR "|
" operator between them. Of course, you'll have to watch out for unescaped characters when building the expression, or a failure to compile it because of complexity or size limitations.
Another way to do this would be to construct a trie data structure to represent all the candidate substrings (this may somewhat duplicate what the regex matcher is doing). As you step through each character in the test string, you would create a new pointer to the root of the trie, and advance existing pointers to the appropriate child (if any). You get a match when any pointer reaches a leaf.
From Bjarne Stroustrup's C++11 FAQ:
The
enum class
es ("new enums", "strong enums") address three problems with traditional C++ enumerations:
- conventional enums implicitly convert to int, causing errors when someone does not want an enumeration to act as an integer.
- conventional enums export their enumerators to the surrounding scope, causing name clashes.
- the underlying type of an
enum
cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible.The new enums are "enum class" because they combine aspects of traditional enumerations (names values) with aspects of classes (scoped members and absence of conversions).
So, as mentioned by other users, the "strong enums" would make the code safer.
The underlying type of a "classic" enum
shall be an integer type large enough to fit all the values of the enum
; this is usually an int
. Also each enumerated type shall be compatible with char
or a signed/unsigned integer type.
This is a wide description of what an enum
underlying type must be, so each compiler will take decisions on his own about the underlying type of the classic enum
and sometimes the result could be surprising.
For example, I've seen code like this a bunch of times:
enum E_MY_FAVOURITE_FRUITS
{
E_APPLE = 0x01,
E_WATERMELON = 0x02,
E_COCONUT = 0x04,
E_STRAWBERRY = 0x08,
E_CHERRY = 0x10,
E_PINEAPPLE = 0x20,
E_BANANA = 0x40,
E_MANGO = 0x80,
E_MY_FAVOURITE_FRUITS_FORCE8 = 0xFF // 'Force' 8bits, how can you tell?
};
In the code above, some naive coder is thinking that the compiler will store the E_MY_FAVOURITE_FRUITS
values into an unsigned 8bit type... but there's no warranty about it: the compiler may choose unsigned char
or int
or short
, any of those types are large enough to fit all the values seen in the enum
. Adding the field E_MY_FAVOURITE_FRUITS_FORCE8
is a burden and doesn't forces the compiler to make any kind of choice about the underlying type of the enum
.
If there's some piece of code that rely on the type size and/or assumes that E_MY_FAVOURITE_FRUITS
would be of some width (e.g: serialization routines) this code could behave in some weird ways depending on the compiler thoughts.
And to make matters worse, if some workmate adds carelessly a new value to our enum
:
E_DEVIL_FRUIT = 0x100, // New fruit, with value greater than 8bits
The compiler doesn't complain about it! It just resizes the type to fit all the values of the enum
(assuming that the compiler were using the smallest type possible, which is an assumption that we cannot do). This simple and careless addition to the enum
could subtlety break related code.
Since C++11 is possible to specify the underlying type for enum
and enum class
(thanks rdb) so this issue is neatly addressed:
enum class E_MY_FAVOURITE_FRUITS : unsigned char
{
E_APPLE = 0x01,
E_WATERMELON = 0x02,
E_COCONUT = 0x04,
E_STRAWBERRY = 0x08,
E_CHERRY = 0x10,
E_PINEAPPLE = 0x20,
E_BANANA = 0x40,
E_MANGO = 0x80,
E_DEVIL_FRUIT = 0x100, // Warning!: constant value truncated
};
Specifying the underlying type if a field have an expression out of the range of this type the compiler will complain instead of changing the underlying type.
I think that this is a good safety improvement.
So Why is enum class preferred over plain enum?, if we can choose the underlying type for scoped(enum class
) and unscoped (enum
) enums what else makes enum class
a better choice?:
int
.I'd like to add the following to Shay Levy's correct answer:
You can make your life easier if you create a little batch script run.cmd
to launch your powershell script:
@echo off & setlocal
set batchPath=%~dp0
powershell.exe -noexit -file "%batchPath%SQLExecutor.ps1" "MY-PC"
Put it in the same path as SQLExecutor.ps1
and from now on you can run it by simply double-clicking on run.cmd
.
Note:
If you require command line arguments inside the run.cmd batch, simply pass them as %1
... %9
(or use %*
to pass all parameters) to the powershell script, i.e.
powershell.exe -noexit -file "%batchPath%SQLExecutor.ps1" %*
The variable batchPath
contains the executing path of the batch file itself (this is what the expression %~dp0
is used for). So you just put the powershell script in the same path as the calling batch file.

Make sure the scp command is available on both sides - both on the client and on the server.
If this is Fedora or Red Hat Enterprise Linux and clones (CentOS), make sure this package is installed:
yum -y install openssh-clients
If you work with Debian or Ubuntu and clones, install this package:
apt-get install openssh-client
Again, you need to do this both on the server and the client, otherwise you can encounter "weird" error messages on your client: scp: command not found
or similar although you have it locally. This already confused thousands of people, I guess :)
The best implementation? That is a hard question because it depends on the usage pattern.
A for nearly all cases reasonable good implementation was proposed in Josh Bloch's Effective Java in Item 8 (second edition). The best thing is to look it up there because the author explains there why the approach is good.
Create a int result
and assign a non-zero value.
For every field f
tested in the equals()
method, calculate a hash code c
by:
boolean
:
calculate (f ? 0 : 1)
;byte
, char
, short
or int
: calculate (int)f
;long
: calculate (int)(f ^ (f >>> 32))
;float
: calculate Float.floatToIntBits(f)
;double
: calculate Double.doubleToLongBits(f)
and handle the return value like every long value;hashCode()
method or 0 if f == null
;Combine the hash value c
with result
:
result = 37 * result + c
Return result
This should result in a proper distribution of hash values for most use situations.
Well if you want to use java.util.Date only, here is a small trick you can use:
String dateString = Long.toString(Date.UTC(date.getYear(), date.getMonth(), date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds()));
You can use the Javascript library PDF.JS to display a PDF inside a div. The size of the PDF can be adjusted according to the size of the div. You can also setup event handlers for moving to next / previous pages of the PDF.

The new way of doing it with php7.4 is Spread operator [...]
$parts = ['apple', 'pear'];
$fruits = ['banana', 'orange', ...$parts, 'watermelon'];
var_dump($fruits);
Spread operator should have better performance than array_merge
A significant advantage of Spread operator is that it supports any traversable objects, while the array_merge function only supports arrays.

Quick summary, you can do either:
Include the JavaFX modules via --module-path
and --add-modules
like in José's answer.
OR
Once you have JavaFX libraries added to your project (either manually or via maven/gradle import), add the module-info.java
file similar to the one specified in this answer. (Note that this solution makes your app modular, so if you use other libraries, you will also need to add statements to require their modules inside the module-info.java
file).
This answer is a supplement to Jose's answer.
The situation is this:
IllegalAccessError
involving an "unnamed module" when trying to launch the app.Excerpt for a stack trace generating an IllegalAccessError

Exception running application org.jewelsea.demo.javafx.springboot.Main
OK, now you are kind of stuck and have no clue what is going on.
What has actually happened is this:
So it seems everything should be OK. BUT, when you run your application, the code in the JavaFX modules is failing when trying to use reflection to instantiate instances of your application class (when you invoke launch) and your FXML controller classes (when you load FXML). Without some help, this use of reflection can fail in some cases, generating the obscure IllegalAccessError
. This is due to a Java module system security feature which does not allow code from other modules to use reflection on your classes unless you explicitly allow it (and the JavaFX application launcher and FXMLLoader both require reflection in their current implementation in order for them to function correctly).
This is where some of the other answers to this question, which reference module-info.java
, come into the picture.
So let's take a crash course in Java modules:
The key part is this:
4.9. Opens
If we need to allow reflection of private types, but we don't want all of our code exposed, we can use the opens directive to expose specific packages.
But remember, this will open the package up to the entire world, so make sure that is what you want:
module my.module { opens com.my.package; }
So, perhaps you don't want to open your package to the entire world, then you can do:
4.10. Opens … To
Okay, so reflection is great sometimes, but we still want as much security as we can get from encapsulation. We can selectively open our packages to a pre-approved list of modules, in this case, using the opens…to directive:
module my.module { opens com.my.package to moduleOne, moduleTwo, etc.; }
So, you end up creating a src/main/java/module-info.java class which looks like this:
module org.jewelsea.demo.javafx.springboot {
requires javafx.fxml;
requires javafx.controls;
requires javafx.graphics;
opens org.jewelsea.demo.javafx.springboot to javafx.graphics,javafx.fxml;
}
Where, org.jewelsea.demo.javafx.springboot
is the name of the package which contains the JavaFX Application class and JavaFX Controller classes (replace this with the appropriate package name for your application). This tells the Java runtime that it is OK for classes in the javafx.graphics
and javafx.fxml
to invoke reflection on the classes in your org.jewelsea.demo.javafx.springboot
package. Once this is done, and the application is compiled and re-run things will work fine and the IllegalAccessError
generated by JavaFX's use of reflection will no longer occur.
But what if you don't want to create a module-info.java file
If instead of using the the Run button in the top toolbar of IDE to run your application class directly, you instead:
javafx.run
.Run Maven Build
or Debug...
.Then the app will run without the module-info.java
file. I guess this is because the maven plugin is smart enough to dynamically include some kind of settings which allows the app to be reflected on by the JavaFX classes even without a module-info.java
file, though I don't know how this is accomplished.
To get that setting transferred to the Run button in the top toolbar, right-click on the javafx.run
Maven target and choose the option to Create Run/Debug Configuration
for the target. Then you can just choose Run from the top toolbar to execute the Maven target.
Firebase provides some good features like real time change reflection , easy integration of authentication mechanism , and lots of other built-in features for rapid web development. Firebase, really makes Web development so simple that never exists. Firebase database is a fork of MongoDB.
What's the advantage of using Firebase over MongoDB?
You can take advantage of all built-in features of Firebase over MongoDB.
By default, git will update execute file permissions if you change them. It will not change or track any other permissions.
If you don't see any changes when modifying execute permission, you probably have a configuration in git which ignore file mode.
Look into your project, in the .git
folder for the config
file and you should see something like this:
[core]
filemode = false
You can either change it to true
in your favorite text editor, or run:
git config core.filemode true
Then, you should be able to commit normally your files. It will only commit the permission changes.
My solution to this problem was to use the $() sub-expression block.
Add-Type -Language CSharp @"
public class Thing{
public string Name;
}
"@;
$x = New-Object Thing
$x.Name = "Bill"
Write-Output "My name is $($x.Name)"
Write-Output "This won't work right: $x.Name"
Gives:
My name is Bill
This won't work right: Thing.Name
Underlying cause:
Content scripts are executed in an "isolated world" environment.
Solution::
To access functions/variables of the page context ("main world") you have to inject the code into the page itself using DOM. Same thing if you want to expose your functions/variables to the page context (in your case it's the state()
method).
Note in case communication with the page script is needed:
Use DOM CustomEvent
handler. Examples: one, two, and three.
Note in case chrome
API is needed in the page script:
Since chrome.*
APIs can't be used in the page script, you have to use them in the content script and send the results to the page script via DOM messaging (see the note above).
Safety warning:
A page may redefine or augment/hook a built-in prototype so your exposed code may fail if the page did it in an incompatible fashion. If you want to make sure your exposed code runs in a safe environment then you should either a) declare your content script with "run_at": "document_start" and use Methods 2-3 not 1, or b) extract the original native built-ins via an empty iframe, example. Note that with document_start
you may need to use DOMContentLoaded
event inside the exposed code to wait for DOM.
This is the easiest/best method when you have lots of code. Include your actual JS code in a file within your extension, say script.js
. Then let your content script be as follows (explained here: Google Chome “Application Shortcut” Custom Javascript):
var s = document.createElement('script');
// TODO: add "script.js" to web_accessible_resources in manifest.json
s.src = chrome.runtime.getURL('script.js');
s.onload = function() {
this.remove();
};
(document.head || document.documentElement).appendChild(s);
Note: For security reasons, Chrome prevents loading of js files. Your file must be added as a "web_accessible_resources"
item (example) :
// manifest.json must include:
"web_accessible_resources": ["script.js"],
If not, the following error will appear in the console:
Denying load of chrome-extension://[EXTENSIONID]/script.js. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.
This method is useful when you want to quickly run a small piece of code. (See also: How to disable facebook hotkeys with Chrome extension?).
var actualCode = `// Code here.
// If you want to use a variable, use $ and curly braces.
// For example, to use a fixed random number:
var someFixedRandomValue = ${ Math.random() };
// NOTE: Do not insert unsafe variables in this way, see below
// at "Dynamic values in the injected code"
`;
var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();
Note: template literals are only supported in Chrome 41 and above. If you want the extension to work in Chrome 40-, use:
var actualCode = ['/* Code here. Example: */' + 'alert(0);',
'// Beware! This array have to be joined',
'// using a newline. Otherwise, missing semicolons',
'// or single-line comments (//) will mess up your',
'// code ----->'].join('\n');
For a big chunk of code, quoting the string is not feasible. Instead of using an array, a function can be used, and stringified:
var actualCode = '(' + function() {
// All code is executed in a local scope.
// For example, the following does NOT overwrite the global `alert` method
var alert = null;
// To overwrite a global variable, prefix `window`:
window.alert = null;
} + ')();';
var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();
This method works, because the +
operator on strings and a function converts all objects to a string. If you intend on using the code more than once, it's wise to create a function to avoid code repetition. An implementation might look like:
function injectScript(func) {
var actualCode = '(' + func + ')();'
...
}
injectScript(function() {
alert("Injected script");
});
Note: Since the function is serialized, the original scope, and all bound properties are lost!
var scriptToInject = function() {
console.log(typeof scriptToInject);
};
injectScript(scriptToInject);
// Console output: "undefined"
Sometimes, you want to run some code immediately, e.g. to run some code before the <head>
element is created. This can be done by inserting a <script>
tag with textContent
(see method 2/2b).
An alternative, but not recommended is to use inline events. It is not recommended because if the page defines a Content Security policy that forbids inline scripts, then inline event listeners are blocked. Inline scripts injected by the extension, on the other hand, still run. If you still want to use inline events, this is how:
var actualCode = '// Some code example \n' +
'console.log(document.documentElement.outerHTML);';
document.documentElement.setAttribute('onreset', actualCode);
document.documentElement.dispatchEvent(new CustomEvent('reset'));
document.documentElement.removeAttribute('onreset');
Note: This method assumes that there are no other global event listeners that handle the reset
event. If there is, you can also pick one of the other global events. Just open the JavaScript console (F12), type document.documentElement.on
, and pick on of the available events.
Occasionally, you need to pass an arbitrary variable to the injected function. For example:
var GREETING = "Hi, I'm ";
var NAME = "Rob";
var scriptToInject = function() {
alert(GREETING + NAME);
};
To inject this code, you need to pass the variables as arguments to the anonymous function. Be sure to implement it correctly! The following will not work:
var scriptToInject = function (GREETING, NAME) { ... };
var actualCode = '(' + scriptToInject + ')(' + GREETING + ',' + NAME + ')';
// The previous will work for numbers and booleans, but not strings.
// To see why, have a look at the resulting string:
var actualCode = "(function(GREETING, NAME) {...})(Hi, I'm ,Rob)";
// ^^^^^^^^ ^^^ No string literals!
The solution is to use JSON.stringify
before passing the argument. Example:
var actualCode = '(' + function(greeting, name) { ...
} + ')(' + JSON.stringify(GREETING) + ',' + JSON.stringify(NAME) + ')';
If you have many variables, it's worthwhile to use JSON.stringify
once, to improve readability, as follows:
...
} + ')(' + JSON.stringify([arg1, arg2, arg3, arg4]) + ')';
changing:
collection.fetch({ data: { page: 1} });
to:
collection.fetch({ data: $.param({ page: 1}) });
So with out over doing it, this is called with your {data: {page:1}}
object as options
Backbone.sync = function(method, model, options) {
var type = methodMap[method];
// Default JSON-request options.
var params = _.extend({
type: type,
dataType: 'json',
processData: false
}, options);
// Ensure that we have a URL.
if (!params.url) {
params.url = getUrl(model) || urlError();
}
// Ensure that we have the appropriate request data.
if (!params.data && model && (method == 'create' || method == 'update')) {
params.contentType = 'application/json';
params.data = JSON.stringify(model.toJSON());
}
// For older servers, emulate JSON by encoding the request into an HTML-form.
if (Backbone.emulateJSON) {
params.contentType = 'application/x-www-form-urlencoded';
params.processData = true;
params.data = params.data ? {model : params.data} : {};
}
// For older servers, emulate HTTP by mimicking the HTTP method with `_method`
// And an `X-HTTP-Method-Override` header.
if (Backbone.emulateHTTP) {
if (type === 'PUT' || type === 'DELETE') {
if (Backbone.emulateJSON) params.data._method = type;
params.type = 'POST';
params.beforeSend = function(xhr) {
xhr.setRequestHeader('X-HTTP-Method-Override', type);
};
}
}
// Make the request.
return $.ajax(params);
};
So it sends the 'data' to jQuery.ajax which will do its best to append whatever params.data
is to the URL.
You need to read and write document.cookie
if (document.cookie.indexOf("visited=") >= 0) {
// They've been here before.
alert("hello again");
}
else {
// set a new cookie
expiry = new Date();
expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes
// Date()'s toGMTSting() method will format the date correctly for a cookie
document.cookie = "visited=yes; expires=" + expiry.toGMTString();
alert("this is your first time");
}
Don't forget the ∧ (logical and) and ∨ (logical or) characters, that's what I use for indicating sort direction: HTML entities ∧
& ∨
respectively.
var tooLong = document.getElementById("longText").value;
if (tooLong.length() > 18){
$('#longText').css('text-overflow', 'ellipsis');
}
If that's a valid date/time entry then excel simply stores it as a number (days are integers and the time is the decimal part) so you can do a simple subtraction.
I'm not sure if 7/6 is 7th June or 6th July, assuming the latter then it's a future date so you can get the difference in days with
=INT(A1-TODAY())
Make sure you format result cell as general or number (not date)

You can use CSS3 'transform':
CSS:
.popup-bck{
background-color: rgba(102, 102, 102, .5);
position: fixed;
width: 100%;
height: 100%;
top: 0;
left: 0;
z-index: 10;
}
.popup-content-box{
background-color: white;
position: fixed;
top: 50%;
left: 50%;
z-index: 11;
-webkit-transform: translate(-50%, -50%);
-moz-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
-o-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}
HTML:
<div class="popup-bck"></div>
<div class="popup-content-box">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
</div>
*so you don't have to use margin-left: -width/2 px;
Change the img-class responsive to:
.img-responsive, x:-moz-any-link {
display: block;
max-width: 100%;
width: auto;
height: auto;
Highlight a single null character, goto find replace - it usually automatically inserts the highlighted text into the find box. Enter a space into or leave blank the replace box.
There is a nice css tricks article about this here: https://css-tricks.com/gradient-borders-in-css/
I was able to come up with a pretty simple, single element, solution to this using multiple backgrounds and the background-origin property.
.wrapper {
background: linear-gradient(#222, #222),
linear-gradient(to right, red, purple);
background-origin: padding-box, border-box;
background-repeat: no-repeat; /* this is important */
border: 5px solid transparent;
}
The nice things about this approach are:

I will say It 's just shorthand syntax for get reference of html element during debugging time , normaly these kind of task will perform by these method
document.getElementById , document.getElementsByClassName , document.querySelector
so clicking on an html element and getting a reference variable ($0) in console is a huge time saving during the day
Using the base
package:
df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))
# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]
# One line
df[df$name %in% c("Tom", "Lynn"), ]
Output:
days name
1 88 Lynn
2 11 Tom
6 1 Tom
7 222 Lynn
8 2 Lynn
Using sqldf
:
library(sqldf)
# Two alternatives:
sqldf('SELECT *
FROM df
WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
FROM df
WHERE name IN ("Tom", "Lynn")')
If you are using PHP you might also want to take a look at minify which can minify and combine JavaScript files. The integration is pretty easy and can be done by defined groups of files or an easy query string. Minified files are also cached to reduce the server load and you can add expire headers through minify.
Haru is a free, cross platform, open-sourced software library for generating PDF written in ANSI-C. It can work as both a static-library (.a, .lib) and a shared-library (.so, .dll).

Workbooks.Open Filename:=filepath, ReadOnly:=True
Or, as pointed out in a comment, to keep a reference to the opened workbook:
Dim book As Workbook
Set book = Workbooks.Open(Filename:=filepath, ReadOnly:=True)
This is not something you can do in a foolproof way. One possibility would be to examine every character in the file to ensure that it doesn't contain any characters in the ranges 0x00 - 0x1f
or 0x7f -0x9f
but, as I said, this may be true for any number of files, including at least one other variant of ISO8859.
Another possibility is to look for specific words in the file in all of the languages supported and see if you can find them.
So, for example, find the equivalent of the English "and", "but", "to", "of" and so on in all the supported languages of 8859-1 and see if they have a large number of occurrences within the file.
I'm not talking about literal translation such as:
English French
------- ------
of de, du
and et
the le, la, les
although that's possible. I'm talking about common words in the target language (for all I know, Icelandic has no word for "and" - you'd probably have to use their word for "fish" [sorry that's a little stereotypical, I didn't mean any offense, just illustrating a point]).
Well I'm not exactly sure why your code is not working because I usually follow a different approach when trying to accomplish something similar.
But your code is erroring out.. There seems to be an issue with the way you are using scale
I got the jQuery to actually execute by changing your code to the following.
$(document).ready(function(){
$('img').hover(function() {
$(this).css("cursor", "pointer");
$(this).toggle({
effect: "scale",
percent: "90%"
},200);
}, function() {
$(this).toggle({
effect: "scale",
percent: "80%"
},200);
});
});
But I have always done it by using CSS
to setup my scaling and transition..
Here is an example, hopefully it helps.
$(document).ready(function(){
$('#content').hover(function() {
$("#content").addClass('transition');
}, function() {
$("#content").removeClass('transition');
});
});
I prefer to do it by using a BAT file.
With BAT file you have more control and can do whatever you want.
string batFileName = path + @"\" + Guid.NewGuid() + ".bat";
using (StreamWriter batFile = new StreamWriter(batFileName))
{
batFile.WriteLine($"YOUR COMMAND");
batFile.WriteLine($"YOUR COMMAND");
batFile.WriteLine($"YOUR COMMAND");
}
ProcessStartInfo processStartInfo = new ProcessStartInfo("cmd.exe", "/c " + batFileName);
processStartInfo.UseShellExecute = true;
processStartInfo.CreateNoWindow = true;
processStartInfo.WindowStyle = ProcessWindowStyle.Normal;
Process p = new Process();
p.StartInfo = processStartInfo;
p.Start();
p.WaitForExit();
File.Delete(batFileName);
I am on shared hosting, so I can't do a lot of queries otherwise I get a blank page.
That sounds very peculiar. I've got the cheapest PHP hosting package I could find for my last project - and it does not behave like this. I would not pay for a service which did. Indeed, I'm stumped to even know how I could configure a server to replicate this behaviour.
Regardless of why it behaves this way, adding a sleep in the middle of the script cannot resolve the problem.
Since, presumably, you control your product catalog, new products should be relatively infrequent (or are you trying to get stock reports?). If you control when you change the data, why run the scripts automatically? Or do you mean that you already have these URLs and you get the expected files when you run them one at a time?
Removing the space between @ and taglib did the trick for me: <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
In C++ you can declare a string like this:
#include <string>
using namespace std;
int main()
{
string str1("argue2000"); //define a string and Initialize str1 with "argue2000"
string str2 = "argue2000"; // define a string and assign str2 with "argue2000"
string str3; //just declare a string, it has no value
return 1;
}
List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.
Try comparing the value of the column to the DBNull.Value
value to filter and manage null values in whatever way you see fit.
foreach(DataRow row in table.Rows)
{
object value = row["ColumnName"];
if (value == DBNull.Value)
// do something
else
// do something else
}
More information about the DBNull class
If you want to check if a null value exists in the table you can use this method:
public static bool HasNull(this DataTable table)
{
foreach (DataColumn column in table.Columns)
{
if (table.Rows.OfType<DataRow>().Any(r => r.IsNull(column)))
return true;
}
return false;
}
which will let you write this:
table.HasNull();
I usually combine PointToScreen
and PointToClient
:
Point locationOnForm = control.FindForm().PointToClient(
control.Parent.PointToScreen(control.Location));
If you want to reassign an element in an array, you can do the following:
var blah = ['Jan', 'Fed', 'Apr'];
console.log(blah);
function reassign(array, index, newValue) {
array[index] = newValue;
return array;
}
reassign(blah, [2], 'Mar');
You can do that with StringUtils
(from Apache Commons Lang). It avoids index-magic, so it's easier to understand. Unfortunately substringAfterLast
returns empty string when there is no separator in the input string so we need the if
statement for that case.
public static String getLastWord(String input) {
String wordSeparator = " ";
boolean inputIsOnlyOneWord = !StringUtils.contains(input, wordSeparator);
if (inputIsOnlyOneWord) {
return input;
}
return StringUtils.substringAfterLast(input, wordSeparator);
}
You could put a crontab file in /etc/cron.d
which would run a script that would run your command and then delete the crontab file in /etc/cron.d
. Of course, that means your script would need to run as root.
You can do this concisely using .filter
. The following example will hide all .testimonial divs containing the word "something":
$(".testimonial").filter(function() {
return $(this).text().toLowerCase().indexOf("something") !== -1;
}).hide();
Other solutions are great but they didn't take care of the fact that watermark shouldn't get selected on selection from the mouse. This fiddle takes care or that: https://jsfiddle.net/MiKr13/d1r4o0jg/9/

background: '#ccc';
position: absolute;
cursor: default;
user-select: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
right: 5px;

}
My approach to this sort of problem is to use a delegate protocol between the cell and the tableview. This allows you to keep the button handler in the cell subclass, which enables you to assign the touch up action handler to the prototype cell in Interface Builder, while still keeping the button handler logic in the view controller.
It also avoids the potentially fragile approach of navigating the view hierarchy or the use of the tag
property, which has issues when cells indexes change (as a result of insertion, deletion or reordering)
CellSubclass.swift
protocol CellSubclassDelegate: class {
func buttonTapped(cell: CellSubclass)
}
class CellSubclass: UITableViewCell {
@IBOutlet var someButton: UIButton!
weak var delegate: CellSubclassDelegate?
override func prepareForReuse() {
super.prepareForReuse()
self.delegate = nil
}
@IBAction func someButtonTapped(sender: UIButton) {
self.delegate?.buttonTapped(self)
}
ViewController.swift
class MyViewController: UIViewController, CellSubclassDelegate {
@IBOutlet var tableview: UITableView!
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! CellSubclass
cell.delegate = self
// Other cell setup
}
// MARK: CellSubclassDelegate
func buttonTapped(cell: CellSubclass) {
guard let indexPath = self.tableView.indexPathForCell(cell) else {
// Note, this shouldn't happen - how did the user tap on a button that wasn't on screen?
return
}
// Do whatever you need to do with the indexPath
print("Button tapped on row \(indexPath.row)")
}
}

brew update
brew install vim && brew install macvim
brew link macvim
You now have the latest versions of vim and macvim managed by brew. Run brew update && brew upgrade
every once in a while to upgrade them.
This includes the installation of the CLI mvim
and the mac application (which both point to the same thing).
I use this setup and it works like a charm. Brew even takes care of installing vim with the preferable options.
Have adapted julmot's answer in order to get a more complete result. This method will also return styles where the class is part for the selector.
//Get all styles where the provided class is involved
//Input parameters should be css selector such as .myClass or #m
//returned as an array of tuples {selectorText:"", styleDefinition:""}
function getStyleWithCSSSelector(cssSelector) {
var styleSheets = window.document.styleSheets;
var styleSheetsLength = styleSheets.length;
var arStylesWithCSSSelector = [];
//in order to not find class which has the current name as prefix
var arValidCharsAfterCssSelector = [" ", ".", ",", "#",">","+",":","["];
//loop through all the stylessheets in the bor
for(var i = 0; i < styleSheetsLength; i++){
var classes = styleSheets[i].rules || styleSheets[i].cssRules;
var classesLength = classes.length;
for (var x = 0; x < classesLength; x++) {
//check for any reference to the class in the selector string
if(typeof classes[x].selectorText != "undefined"){
var matchClass = false;
if(classes[x].selectorText === cssSelector){//exact match
matchClass=true;
}else {//check for it as part of the selector string
//TODO: Optimize with regexp
for (var j=0;j<arValidCharsAfterCssSelector.length; j++){
var cssSelectorWithNextChar = cssSelector+ arValidCharsAfterCssSelector[j];
if(classes[x].selectorText.indexOf(cssSelectorWithNextChar)!=-1){
matchClass=true;
//break out of for-loop
break;
}
}
}
if(matchClass === true){
//console.log("Found "+ cssSelectorWithNextChar + " in css class definition " + classes[x].selectorText);
var styleDefinition;
if(classes[x].cssText){
styleDefinition = classes[x].cssText;
} else {
styleDefinition = classes[x].style.cssText;
}
if(styleDefinition.indexOf(classes[x].selectorText) == -1){
styleDefinition = classes[x].selectorText + "{" + styleDefinition + "}";
}
arStylesWithCSSSelector.push({"selectorText":classes[x].selectorText, "styleDefinition":styleDefinition});
}
}
}
}
if(arStylesWithCSSSelector.length==0) {
return null;
}else {
return arStylesWithCSSSelector;
}
}
In addition, I've made a function which collects the css style definitions to the sub-tree of a root node your provide (through a jquery selector).
function getAllCSSClassDefinitionsForSubtree(selectorOfRootElement){
//stack in which elements are pushed and poped from
var arStackElements = [];
//dictionary for checking already added css class definitions
var existingClassDefinitions = {}
//use jquery for selecting root element
var rootElement = $(selectorOfRootElement)[0];
//string with the complete CSS output
var cssString = "";
console.log("Fetching all classes used in sub tree of " +selectorOfRootElement);
arStackElements.push(rootElement);
var currentElement;
while(currentElement = arStackElements.pop()){
currentElement = $(currentElement);
console.log("Processing element " + currentElement.attr("id"));
//Look at class attribute of element
var classesString = currentElement.attr("class");
if(typeof classesString != 'undefined'){
var arClasses = classesString.split(" ");
//for each class in the current element
for(var i=0; i< arClasses.length; i++){
//fetch the CSS Styles for a single class. Need to append the . char to indicate its a class
var arStylesWithCSSSelector = getStyleWithCSSSelector("."+arClasses[i]);
console.log("Processing class "+ arClasses[i]);
if(arStylesWithCSSSelector != null){
//console.log("Found "+ arStylesWithCSSSelector.length + " CSS style definitions for class " +arClasses[i]);
//append all found styles to the cssString
for(var j=0; j< arStylesWithCSSSelector.length; j++){
var tupleStyleWithCSSSelector = arStylesWithCSSSelector[j];
//check if it has already been added
if(typeof existingClassDefinitions[tupleStyleWithCSSSelector.selectorText] === "undefined"){
//console.log("Adding " + tupleStyleWithCSSSelector.styleDefinition);
cssString+= tupleStyleWithCSSSelector.styleDefinition;
existingClassDefinitions[tupleStyleWithCSSSelector.selectorText] = true;
}else {
//console.log("Already added " + tupleStyleWithCSSSelector.styleDefinition);
}
}
}
}
}
//push all child elments to stack
if(currentElement.children().length>0){
arStackElements= arStackElements.concat(currentElement.children().toArray());
}
}
console.log("Found " + Object.keys(existingClassDefinitions).length + " CSS class definitions");
return cssString;
}
Note that if a class is defined several times with the same selector, the above function will only pick up the first. Note that the example uses jQuery (but cab relatively easily be rewritten to not use it)
I think that in answer should be pointed which type of object do you get in all methods suggested above: is it Series or DataFrame.
When you get column by w.female.
or w[[2]]
(where, suppose, 2 is number of your column) you'll get back DataFrame.
So in this case you can use DataFrame methods like .replace
.
When you use .loc
or iloc
you get back Series, and Series don't have .replace
method, so you should use methods like apply
, map
and so on.
Fink appears to have a full set of Boost packages...

Excel 2010 driver is 64 bit, while the default SSMS import export wizard is 32 therefore the error message.
You can import using the Import Export Data (64 bit) tool. ("C:\Program Files\Microsoft SQL Server\110\DTS\Binn\DTSWizard.exe") notice the path is not Program Files x86.
Nowadays, you can simply drag and drop the Android apk to the emulator and it will automatically starts installing.
you need to use os.system
module to execute shell command
import os
os.system('command')
if you want to save the output for later use, you need to use subprocess
module
import subprocess
child = subprocess.Popen('command',stdout=subprocess.PIPE,shell=True)
output = child.communicate()[0]
This reply may be late but it may help users having similar problem. The opencv-contrib (available at https://github.com/opencv/opencv_contrib/releases) contains extra modules but the build procedure has to be done from core opencv (available at from https://github.com/opencv/opencv/releases) modules.
Follow below steps (assuming you are building it using CMake GUI)
Download openCV (from https://github.com/opencv/opencv/releases) and unzip it somewhere on your computer. Create build folder inside it
Download exra modules from OpenCV. (from https://github.com/opencv/opencv_contrib/releases). Ensure you download the same version.
Unzip the folder.
Open CMake
Click Browse Source and navigate to your openCV folder.
Click Browse Build and navigate to your build Folder.
Click the configure button. You will be asked how you would like to generate the files. Choose Unix-Makefile from the drop down menu and Click OK. CMake will perform some tests and return a set of red boxes appear in the CMake Window.
Search for "OPENCV_EXTRA_MODULES_PATH" and provide the path to modules folder (e.g. /Users/purushottam_d/Programs/OpenCV3_4_5_contrib/modules)
Click Configure again, then Click Generate.
Go to build folder
# cd build
# make
# sudo make install

You can't float or set the width of an inline element. Remove display: inline;
from both classes and your markup should present fine.
EDIT: You can set the width, but it will cause the element to be rendered as a block.
# THIS WORK FOR ME
# Get all diferent values
df3 = pd.merge(df1, df2, how='outer', indicator='Exist')
df3 = df3.loc[df3['Exist'] != 'both']
# If you like to filter by a common ID
df3 = pd.merge(df1, df2, on="Fruit", how='outer', indicator='Exist')
df3 = df3.loc[df3['Exist'] != 'both']
$(document).click(function() {
$(".overlay-window").hide();
});
$(".overlay-window").click(function() {
return false;
});
If you click on the document, hide a given element, unless you click on that same element.
The value you have passed as the file descriptor is not valid. It is either negative or does not represent a currently open file or socket.
So you have either closed the socket before calling write()
or you have corrupted the value of 'sockfd' somewhere in your code.
It would be useful to trace all calls to close()
, and the value of 'sockfd' prior to the write()
calls.
Your technique of only printing error messages in debug mode seems to me complete madness, and in any case calling another function between a system call and perror()
is invalid, as it may disturb the value of errno
. Indeed it may have done so in this case, and the real underlying error may be different.
Here is another example showing the use of gather
from tidyr
. You can select the columns to gather
either by removing them individually (as I do here), or by including the years you want explicitly.
Note that, to handle the commas (and X's added if check.names = FALSE
is not set), I am also using dplyr
's mutate with parse_number
from readr
to convert the text values back to numbers. These are all part of the tidyverse
and so can be loaded together with library(tidyverse)
wide %>%
gather(Year, Value, -Code, -Country) %>%
mutate(Year = parse_number(Year)
, Value = parse_number(Value))
Returns:
Code Country Year Value

You can use a third-party importer
to customise @import
semantics.
node-sass-import-once, which works with node-sass (for Node.js) can inline import CSS files.
Example of direct usage:
var sass = require('node-sass');,
importOnce = require('node-sass-import-once');
sass.render({
file: "input.scss",
importer: importOnce,
importOnce: {
css: true,
}
});
Example grunt-sass config:
var importOnce = require("node-sass-import-once");
grunt.loadNpmTasks("grunt-sass");
grunt.initConfig({
sass: {
options: {
sourceMap: true,
importer: importOnce
},
dev: {
files: {
"dist/style.css": "scss/**/*.scss"
}
}
});
Note that node-sass-import-once cannot currently import Sass partials without an explicit leading underscore. For example with the file partials/_partial.scss
:
@import partials/_partial.scss
succeeds@import * partials/partial.scss
failsIn general, be aware that a custom importer could change any import semantics. Read the docs before you start using it.
My answer comes from here
You can make a derived class, which will set the timeout property of the base WebRequest
class:
using System;
using System.Net;
public class WebDownload : WebClient
{
/// <summary>
/// Time in milliseconds
/// </summary>
public int Timeout { get; set; }
public WebDownload() : this(60000) { }
public WebDownload(int timeout)
{
this.Timeout = timeout;
}
protected override WebRequest GetWebRequest(Uri address)
{
var request = base.GetWebRequest(address);
if (request != null)
{
request.Timeout = this.Timeout;
}
return request;
}
}
and you can use it just like the base WebClient class.

Internally, string::operator==()
is using string::compare()
. Please refer to: CPlusPlus - string::operator==()
I wrote a small application to compare the performance, and apparently if you compile and run your code on debug environment the string::compare()
is slightly faster than string::operator==()
. However if you compile and run your code in Release environment, both are pretty much the same.
FYI, I ran 1,000,000 iteration in order to come up with such conclusion.
In order to prove why in debug environment the string::compare is faster, I went to the assembly and here is the code:
DEBUG BUILD
string::operator==()
if (str1 == str2)
00D42A34 lea eax,[str2]
00D42A37 push eax
00D42A38 lea ecx,[str1]
00D42A3B push ecx
00D42A3C call std::operator==<char,std::char_traits<char>,std::allocator<char> > (0D23EECh)
00D42A41 add esp,8
00D42A44 movzx edx,al
00D42A47 test edx,edx
00D42A49 je Algorithm::PerformanceTest::stringComparison_usingEqualOperator1+0C4h (0D42A54h)
string::compare()
if (str1.compare(str2) == 0)
00D424D4 lea eax,[str2]
00D424D7 push eax
00D424D8 lea ecx,[str1]
00D424DB call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0D23582h)
00D424E0 test eax,eax
00D424E2 jne Algorithm::PerformanceTest::stringComparison_usingCompare1+0BDh (0D424EDh)
You can see that in string::operator==(), it has to perform extra operations (add esp, 8 and movzx edx,al)
RELEASE BUILD
string::operator==()
if (str1 == str2)
008533F0 cmp dword ptr [ebp-14h],10h
008533F4 lea eax,[str2]
008533F7 push dword ptr [ebp-18h]
008533FA cmovae eax,dword ptr [str2]
008533FE push eax
008533FF push dword ptr [ebp-30h]
00853402 push ecx
00853403 lea ecx,[str1]
00853406 call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0853B80h)
string::compare()
if (str1.compare(str2) == 0)
00853830 cmp dword ptr [ebp-14h],10h
00853834 lea eax,[str2]
00853837 push dword ptr [ebp-18h]
0085383A cmovae eax,dword ptr [str2]
0085383E push eax
0085383F push dword ptr [ebp-30h]
00853842 push ecx
00853843 lea ecx,[str1]
00853846 call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0853B80h)
Both assembly code are very similar as the compiler perform optimization.
Finally, in my opinion, the performance gain is negligible, hence I would really leave it to the developer to decide on which one is the preferred one as both achieve the same outcome (especially when it is release build).
For Debian users, the following may be of use:
sudo -s
apt install libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev libtk8.5 libgdm-dev libdb4o-cil-dev libpcap-dev
Then cd to the folder with the Python 3.X library source code and run:
./configure
make
make install
Maybe something like this:
yourformName.YourLabel.Font = new Font("Arial", 24,FontStyle.Bold);
Or if you are in the same class as the form then simply do this:
YourLabel.Font = new Font("Arial", 24,FontStyle.Bold);
The constructor takes diffrent parameters (so pick your poison). Like this:
Font(Font, FontStyle)
Font(FontFamily, Single)
Font(String, Single)
Font(FontFamily, Single, FontStyle)
Font(FontFamily, Single, GraphicsUnit)
Font(String, Single, FontStyle)
Font(String, Single, GraphicsUnit)
Font(FontFamily, Single, FontStyle, GraphicsUnit)
Font(String, Single, FontStyle, GraphicsUnit)
Font(FontFamily, Single, FontStyle, GraphicsUnit, Byte)
Font(String, Single, FontStyle, GraphicsUnit, Byte)
Font(FontFamily, Single, FontStyle, GraphicsUnit, Byte, Boolean)
Font(String, Single, FontStyle, GraphicsUnit, Byte, Boolean)
Reference here
If your script is a directory or ZIP file rather than a single python file, __main__.py
will be executed when the "script" is passed as an argument to the python interpreter.
Or, you can declare input number as long, and then let it do the code tango :D ...
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a number");
long n = in.nextLong();
for (long i = 2; i <= n; i++) {
while (n % i == 0) {
System.out.print(", " + i);
n /= i;
}
}
}
Use JQuery
var scale=0.5;
minWidth=50;
minHeight=100;
if($("#id img").width()*scale>minWidth && $("#id img").height()*scale >minHeight)
{
$("#id img").width($("#id img").width()*scale);
$("#id img").height($("#id img").height()*scale);
}
I would make sure you have an index on ColA, and then run both of them and time them. That would give you the best answer.
If it "doesn't care about the output", couldn't the exec to the script be called with the &
to background the process?
EDIT - incorporating what @AdamTheHut commented to this post, you can add this to a call to exec
:
" > /dev/null 2>/dev/null &"
That will redirect both stdio
(first >
) and stderr
(2>
) to /dev/null
and run in the background.
There are other ways to do the same thing, but this is the simplest to read.
An alternative to the above double-redirect:
" &> /dev/null &"

You can use a subquery. The subquery will get the Max(CompletedDate)
. You then take this value and join on your table again to retrieve the note associate with that date:
select ET1.TrainingID,
ET1.CompletedDate,
ET1.Notes
from HR_EmployeeTrainings ET1
inner join
(
select Max(CompletedDate) CompletedDate, TrainingID
from HR_EmployeeTrainings
--where AvantiRecID IS NULL OR AvantiRecID = @avantiRecID
group by TrainingID
) ET2
on ET1.TrainingID = ET2.TrainingID
and ET1.CompletedDate = ET2.CompletedDate
where ET1.AvantiRecID IS NULL OR ET1.AvantiRecID = @avantiRecID
You have to activate the query logging in mysql.
edit /etc/my.cnf
[mysqld] log=/tmp/mysql.log
restart the computer or the mysqld service
service mysqld restart
open phpmyadmin/any application that uses mysql/mysql console and run a query
cat /tmp/mysql.log
( you should see the query )
Just use
int listCount = data.size();
That tells you how many lists there are (assuming none are null). If you want to find out how many strings there are, you'll need to iterate:
int total = 0;
for (List<String> sublist : data) {
// TODO: Null checking
total += sublist.size();
}
// total is now the total number of strings
For those discovering this now and the above answers didn't work, the issue I had was the screen wasn't big enough. I added this when initializing my ChromeDriver, and it fixed the problem:
options.add_argument("window-size=1200x600")
For Intellij IDEA Community 2019.1 you will need to follow these steps :
File -> New -> Edit File Templates.. -> Class -> /* Created by ${USER} on ${DATE} */
//Write a javascript method to bind click event of each "li" item
function BindClickEvent()
{
var selector = '.nav li';
//Removes click event of each li
$(selector ).unbind('click');
//Add click event
$(selector ).bind('click', function()
{
$(selector).removeClass('active');
$(this).addClass('active');
});
}
//first call this method when first time when page load
$( document ).ready(function() {
BindClickEvent();
});
//Call BindClickEvent method from server side
protected void Page_Load(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(Page,GetType(), Guid.NewGuid().ToString(),"BindClickEvent();",true);
}
Try replaceAll()
method of the String
class.
BTW here is the method, return type and parameters.
public String replaceAll(String regex,
String replacement)
Example:
String str = "Hello +-^ my + - friends ^ ^^-- ^^^ +!";
str = str.replaceAll("[-+^]*", "");
It should remove all the {'^', '+', '-'} chars that you wanted to remove!
Another option is to pass the single quote as an awk variable:
awk -v q=\' 'BEGIN {FS=" ";} {printf "%s%s%s ", q, $1, q}'
Simpler example with string concatenation:
# Prints 'test me', *including* the single quotes.
$ awk -v q=\' '{print q $0 q }' <<<'test me'
'test me'
Here is my way.
<?php
define('DEBUG',0);
define('PRODUCTION',1);
#development_mode : DEBUG / PRODUCTION
$development_mode = PRODUCTION;
#Website root path for links
$app_path = 'http://192.168.0.234/dealer/';
#User interface files path
$ui_path = 'ui/';
#Image gallery path
$gallery_path = 'ui/gallery/';
$mysqlserver = "localhost";
$mysqluser = "root";
$mysqlpass = "";
$mysqldb = "dealer_plus";
?>
Any doubts please comment
$fname = "database.php";
$fhandle = fopen($fname,"r");
$content = fread($fhandle,filesize($fname));
$content = str_replace("192.168.1.198", "localhost", $content);
$fhandle = fopen($fname,"w");
fwrite($fhandle,$content);
fclose($fhandle);
Just to give you an another option, you could use https://sourceforge.net/projects/dd2vmdk/ as well. dd2vmdk is a *nix-based program that allows you to mount raw disk images (created by dd, dcfldd, dc3dd, ftk imager, etc) by taking the raw image, analyzing the master boot record (physical sector 0), and getting specific information that is need to create a vmdk file.
Personally, imo Qemu and the Zapotek's raw2vmdk tools are the best overall options to convert dd to vmdks.

I'd the similar problem and excluding the DataSourceAutoConfiguration and HibernateJpaAutoConfiguration solved the problem.
I have added these two lines in my application.properties file and it worked.

On Django 1.2, {{ form.data.field }} and {{ form.field.data }} are all OK, but not {{ form.field.value }}.
As others said, {{ form.field.value }} is Django 1.3+ only, but there's no specification in https://docs.djangoproject.com/en/1.3/topics/forms/. It can be found in https://docs.djangoproject.com/en/1.4/topics/forms/.
I think your question isn't quite clear. There are several answers here on how to catch the data coming into a Linux's serial port, but perhaps your problem is the other way around?
If you need to catch the data coming out of a Linux's serial port and send it to a server, there are several little hardware gizmos that can do this, starting with the simple serial print server such as this Lantronix gizmo.
No, I'm not affiliated with Lantronix in any way.
Just try this in razor
@{
var selectList = new SelectList(
new List<SelectListItem>
{
new SelectListItem {Text = "Google", Value = "Google"},
new SelectListItem {Text = "Other", Value = "Other"},
}, "Value", "Text");
}
and then
@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })
or
@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })
Uh, WHERE mydate<='2008-11-25'
is the way to do it. That should work.
Do you get an error message? Are you using an ancient version of MySQL?
Edit: The following works fine for me on MySQL 5.x
create temporary table foo(d datetime);
insert into foo(d) VALUES ('2000-01-01');
insert into foo(d) VALUES ('2001-01-01');
select * from foo where d <= '2000-06-01';
Go to Xcode preferences by clicking on "Xcode" in the left hand side upper corner.
Select "Text Editing".
Select "Show: Line numbers" and click on check box for enable it.
Close it.
Then you will see the line number in Xcode.
Because otherwise scanf will think you are passing a pointer to a float which is a smaller size than a double, and it will return an incorrect value.
I had similar problem when importing phone number data from excel to mysql database. So a simple trick without the need to identify the length of the phone number (because the length of the phone numbers varied in my data):
UPDATE table SET phone_num = concat('0', phone_num)
I just concated 0 in front of the phone_num
.
Below is Solution with o(n):-
public static void findMaxAndMinValue(int A[]){
int min =0, max = 0;
if(A[0] > A[1] ){
min = A[1];
max = A[0];
}else{
max = A[1];
min = A[0];
}
for(int i = 2;i<A.length ;i++){
if(A[i] > max){
max = A[i];
}
if(min > A[i]){
min = A[i];
}
}
System.out.println("Maxinum Value is "+min+" & Minimum Value is "+max);
}
Sorry for late reply but still felt like posting my answer if it helps.It works for 6 digits OTP.
@Override

{
otp = matcher.group();
}
checkAndSetOTP(otp);
}

if (intentExtras != null)
{

String format = intent.getStringExtra(FORMAT);
if (sms_bundle != null)
{
otpSMSListener.onOTPSMSReceived(format, sms_bundle);
}
else {

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?
Yes. Look at Cython. It does just that: Converts Python to C for speedups.
Try:
.Formula = "='" & strProjectName & "'!" & Cells(2, 7).Address
If your worksheet name (strProjectName
) has spaces, you need to include the single quotes in the formula string.
If this does not resolve it, please provide more information about the specific error or failure.
Update
In comments you indicate you're replacing spaces with underscores. Perhaps you are doing something like:
strProjectName = Replace(strProjectName," ", "_")
But if you're not also pushing that change to the Worksheet.Name
property, you can expect these to happen:
#REF
errorThe reason for both is that you are passing a reference to a worksheet that doesn't exist, which is why you get the #REF error. The file dialog is an attempt to let you correct that reference, by pointing to a file wherein that sheet name does exist. When you cancel out, the #REF error is expected.
So you need to do:
Worksheets(strProjectName).Name = Replace(strProjectName," ", "_")
strProjectName = Replace(strProjectName," ", "_")
Then, your formula should work.
Change your crontab command to
* * * * * (cd /home/udi/foo/ || exit 1; ./bar.py)
The (...)
starts a sub-shell that your crond executes as a single command. The || exit 1
causes your cronjob to fail in case that the directory is unavailable.
Though the other solutions may be more elegant in the long run for your specific scripts, my example could still be useful in cases where you can't modify the program or command that you want to execute.
if you want to include float values also you can use the following code
theValue=$('#balanceinput').val();
var isnum1 = /^\d*\.?\d+$/.test(theValue);
var isnum2 = /^\d*\.?\d+$/.test(theValue.split("").reverse().join(""));
alert(isnum1+' '+isnum2);
this will test for only digits and digits separated with '.' the first test will cover values such as 0.1 and 0 but also .1 , it will not allow 0. so the solution that I propose is to reverse theValue so .1 will be 1. then the same regular expression will not allow it .
example :
theValue=3.4; //isnum1=true , isnum2=true
theValue=.4; //isnum1=true , isnum2=false
theValue=3.; //isnum1=flase , isnum2=true
Based on Martin Atkins' solution, here is a complete, concise pure-Angular solution:
(function() {
var initInjector = angular.injector(['ng']);
var $http = initInjector.get('$http');
$http.get('/config.json').then(
function (response) {
angular.module('config', []).constant('CONFIG', response.data);
angular.element(document).ready(function() {
angular.bootstrap(document, ['myApp']);
});
}
);
})();
This solution uses a self-executing anonymous function to get the $http service, request the config, and inject it into a constant called CONFIG when it becomes available.
Once completely, we wait until the document is ready and then bootstrap the Angular app.
This is a slight enhancement over Martin's solution, which deferred fetching the config until after the document is ready. As far as I know, there is no reason to delay the $http call for that.
Unit Testing
Note: I have discovered this solution does not work well when unit-testing when the code is included in your app.js
file. The reason for this is that the above code runs immediately when the JS file is loaded. This means the test framework (Jasmine in my case) doesn't have a chance to provide a mock implementation of $http
.
My solution, which I'm not completely satisfied with, was to move this code to our index.html
file, so the Grunt/Karma/Jasmine unit test infrastructure does not see it.
Update-Package -reinstall Microsoft.Web.Infrastructure
didn't work for me, as I kept receiving errors that it was already installed.
I had to navigate to the Microsoft.Web.Infrastructure.1.0.0.0 folder in the packages folder and manually delete that folder.
After doing this, running Install-Package Microsoft.Web.Infrastructure
installed it.
Note: CopyLocal
was automatically set to true.
TESTED with jquery 1.11.3 & jquery-ui 1.11.4
$(function() {
$("#draggable").draggable({
revert : function(event, ui) {
// on older version of jQuery use "draggable"
// $(this).data("draggable")
// on 2.x versions of jQuery use "ui-draggable"
// $(this).data("ui-draggable")
$(this).data("uiDraggable").originalPosition = {
top : 0,
left : 0
};
// return boolean
return !event;
// that evaluate like this:
// return event !== false ? false : true;
}
});
$("#droppable").droppable();
});
Of course the method numbers()
returns an array, it's just that you're doing nothing with it. Try this in main()
:
int[] array = numbers(); // obtain the array
System.out.println(Arrays.toString(array)); // now print it
That will show the array in the console.
eval $(cat .env | sed 's/^/export /')
From the bash
manpage:
[[ expression ]]
- return a status of 0 or 1 depending on the evaluation of the conditional expression expression.
And, for expressions, one of the options is:
expression1 && expression2
- true if bothexpression1
andexpression2
are true.
So you can and
them together as follows (-n
is the opposite of -z
so we can get rid of the !
):
if [[ -n "$var" && -e "$var" ]] ; then
echo "'$var' is non-empty and the file exists"
fi
However, I don't think it's needed in this case, -e xyzzy
is true if the xyzzy
file exists and can quite easily handle empty strings. If that's what you want then you don't actually need the -z
non-empty check:
pax> VAR=xyzzy
pax> if [[ -e $VAR ]] ; then echo yes ; fi
pax> VAR=/tmp
pax> if [[ -e $VAR ]] ; then echo yes ; fi
yes
In other words, just use:
if [[ -e "$var" ]] ; then
echo "'$var' exists"
fi
C++20 gives us std::map::contains
to do that.
#include <iostream>
#include <string>
#include <map>
int main()
{
std::map<int, std::string> example = {{1, "One"}, {2, "Two"},
{3, "Three"}, {42, "Don\'t Panic!!!"}};
if(example.contains(42)) {
std::cout << "Found\n";
} else {
std::cout << "Not found\n";
}
}
You need to set the error_reporting value in a .htaccess file. Since there is a parse error, it never runs the error_reporting() function in your PHP code.
Try this in a .htaccess file (assuming you can use one):
php_flag display_errors 1
php_value error_reporting 30719
I think 30719 corresponds to E_ALL but I may be wrong.
Edit Update: http://php.net/manual/en/errorfunc.constants.php
int error_reporting ([ int $level ] )
---
32767 E_ALL (integer)
All errors and warnings, as supported, except of level E_STRICT prior to PHP 5.4.0. 32767 in PHP 5.4.x, 30719 in PHP 5.3.x, 6143 in PHP 5.2.x, 2047 previously
Primary key is a subset of super key. Which is uniquely define and other field are depend on it. In a table their can be just one primary key and rest sub set are candidate key or alternate keys.
Place this code on your body tag

There are at least two ways to do that:
defining context param in web.xml – that breaks "one package for all environments" statement. I don't recommend that
defining system property -Dspring.profiles.active=your-active-profile
I believe that defining system property is a much better approach. So how to define system property for Tomcat? On the internet I could find a lot of advice like "modify catalina.sh" because you will not find any configuration file for doing stuff like that. Modifying catalina.sh is a dirty unmaintainable solution. There is a better way to do that.
Just create file setenv.sh in Tomcat's bin directory with content:
JAVA_OPTS="$JAVA_OPTS -Dspring.profiles.active=dev"
and it will be loaded automatically during running catalina.sh start or run.
Here is a blog describing the above solution.
I took a stab a Adam Boduch's code to output a deep diff - this is entirely untested but the pieces are there:
function diff (obj1, obj2, path) {
obj1 = obj1 || {};
obj2 = obj2 || {};
return _.reduce(obj1, function(result, value, key) {
var p = path ? path + '.' + key : key;
if (_.isObject(value)) {
var d = diff(value, obj2[key], p);
return d.length ? result.concat(d) : result;
}
return _.isEqual(value, obj2[key]) ? result : result.concat(p);
}, []);
}
diff({ foo: 'lol', bar: { baz: true }}, {}) // returns ["foo", "bar.baz"]
You don't need remove, just add again.

is for.
As a quick example:

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)
plt.scatter(t,x,c=y)

A graphical overview (summary in a nutshell)
Since static classes are sealed, they cannot be inherited (except from Object), so the keyword protected is invalid on static classes.
For the defaults if you put no access modifier in front, see here:
Default visibility for C# classes and members (fields, methods, etc.)?
Non-nested
enum public
non-nested classes / structs internal
interfaces internal
delegates in namespace internal
class/struct member(s) private
delegates nested in class/struct private
Nested:
nested enum public
nested interface public
nested class private
nested struct private
Also, there is the sealed-keyword, which makes a class not-inheritable.
Also, in VB.NET, the keywords are sometimes different, so here a cheat-sheet:
In more simple terms:
Technically, the -u
flag adds a tracking reference to the upstream server you are pushing to.
What is important here is that this lets you do a git pull
without supplying any more arguments. For example, once you do a git push -u origin master
, you can later call git pull
and git will know that you actually meant git pull origin master
.
Otherwise, you'd have to type in the whole command.
If you need to get the average color of a rectangular area, rather than the color of a single pixel, please take a look at this other question:
JavaScript - Get average color from a certain area of an image
Anyway, both are done in a very similar way:
To get the color of a single pixel, you would first draw that image to a canvas, which you have already done:
const image = document.getElementById('image');
const canvas = document.createElement('canvas');
const context = canvas.getContext('2d');
const width = image.width;
const height = image.height;
canvas.width = width;
canvas.height = height;
context.drawImage(image, 0, 0, width, height);
And then get the value of a single pixel like this:
const data = context.getImageData(X, Y, 1, 1).data;
// RED = data[0]
// GREEN = data[1]
// BLUE = data[2]
// ALPHA = data[3]
You need to use this same CanvasRenderingContext2D.getImageData() to get the values of the whole image, which you do by changing its third and fourth params. The signature of that function is:
ImageData ctx.getImageData(sx, sy, sw, sh);
sx
: The x coordinate of the upper left corner of the rectangle from which the ImageData will be extracted.sy
: The y coordinate of the upper left corner of the rectangle from which the ImageData will be extracted.sw
: The width of the rectangle from which the ImageData will be extracted.sh
: The height of the rectangle from which the ImageData will be extracted.You can see it returns an ImageData
object, whatever that is. The important part here is that that object has a .data
property which contains all our pixel values.
However, note that .data
property is a 1-dimension Uint8ClampedArray
, which means that all the pixel's components have been flattened, so you are getting something that looks like this:
Let's say you have a 2x2 image like this:
RED PIXEL | GREEN PIXEL
BLUE PIXEL | TRANSPARENT PIXEL
Then, you will get them like this:
[ 255, 0, 0, 255, 0, 255, 0, 255, 0, 0, 255, 255, 0, 0, 0, 0 ]
| RED PIXEL | GREEN PIXEL | BLUE PIXEL | TRANSPAERENT PIXEL |
| 1ST PIXEL | 2ND PIXEL | 3RD PIXEL | 4TH PIXEL |
As calling getImageData
is a slow operation, you can call it only once to get the data of all the image (sw
= image width, sh
= image height).
Then, in the example above, if you want to access the components of the TRANSPARENT PIXEL
, that is, the one at position x = 1, y = 1
of this imaginary image, you would find its first index i
in its ImageData
's data
property as:
const i = (y * imageData.width + x) * 4;

?? Note I'm using a small data URI to avoid Cross-Origin
issues if I include an external image or an answer that is larger than allowed if I try to use a longer data URI.
If you move the cursor around the borders of the asterisk shape, you will see sometimes avgSolidColor
is red, but the pixel you are sampling looks white. That's because even though the R
component for that pixel might be high, the alpha channel is low, so the color is actually an almost transparent shade of red, but avgSolidColor
ignores that.
On the other hand, avgAlphaColor
looks pink. Well, that's actually not true, it just looks pink because we are now using the alpha channel, which makes it semitransparent and allows us to see the background of the page, which in this case is white.
Then, what can we do to fix this? Well, it turns out we just need to use the alpha channel and its inverse as the weights to calculate the components of our new sample, in this case merging it with white, as that's the color we use as background.
That means that if a pixel is R, G, B, A
, where A
is in the interval [0, 1]
, we will compute the inverse of the alpha channel, iA
, and the components of the weighted sample as:
const iA = 1 - A;
const wR = (R * A + 255 * iA) | 0;
const wG = (G * A + 255 * iA) | 0;
const wB = (B * A + 255 * iA) | 0;
Note how the more transparent a pixel is (A
closer to 0), the lighter the color.
Turns out that to copy a complete directory structure gulp
needs to be provided with a base for your gulp.src()
method.
So gulp.src( [ files ], { "base" : "." })
can be used in the structure above to copy all the directories recursively.
If, like me, you may forget this then try:
gulp.copy=function(src,dest){
return gulp.src(src, {base:"."})
.pipe(gulp.dest(dest));
};
In my maven ee project I am using:
<build>
<finalName>shop</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>${maven.war.version}</version>
<configuration><webappDirectory>${project.build.directory}/${project.build.finalName} </webappDirectory>
</configuration>
</plugin>
</plugins>
</build>
Yet another possibility to check, it was my problem this time.
I had added the function to the library, and included the library's output folder in the search path.
But I also had a folder with an older version of the library listed before, so VS was using the old library, and of course not finding the new function.
I used some of the answers and found one that fit my case ( make sure all tasks are in the release branch).
Other methods works as well but I found that they might add lines that I do not need, like merge commits that add no value.
git fetch
git log origin/master..origin/release-1.1 --oneline --no-merges
or you can compare your current with master
git fetch
git log origin/master..HEAD --oneline --no-merges
git fetch
is there to make sure you are using updated info.
In this way each commit will be on a line and you can copy/paste that into an text editor and start comparing the tasks with the commits that will be merged.
For some non-activity classes, like Worker, you're already given a Context object in the public constructor.
Worker(Context context, WorkerParameters workerParams)
You can just use that, e.g., save it to a private Context variable in the class (say, mContext
), and then, for example
mContext.getSystenService(Context.ACTIVITY_SERVICE)
In your case you can use the android.util.Patterns package
.
EditText email = (EditText)findViewById(R.id.user_email);
if(Patterns.EMAIL_ADDRESS.matcher(email.getText().toString()).matches())
Toast.makeText(this, "Email is VALID.", Toast.LENGTH_SHORT).show();
else
Toast.makeText(this, "Email is INVALID.", Toast.LENGTH_SHORT).show();
I got this error when I dynamically read data from a WebRequest
and never closed the Response
.

var request = System.Net.WebRequest.Create(url);
var response = request.GetResponse();
if (response != null) {
stream = response.GetResponseStream();
// I never closed the response thus resulting in the error
response.Close();
}
response = null;
request = null;
return stream;
}
catch (Exception) { }
return null;

Ok, I did a little cross-browser experiment for printing background colors. Just copy, paste & enjoy!
Here it is a full printable HTML page for bootstrap:

I had to do
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().barStyle = .Black
UINavigationBar.appearance().backgroundColor = UIColor.blueColor()
otherwise the background color wouldn't change
I'm following these steps and it's been working so far:
import 'rxjs/add/operator/map';
will resolve your problem
I tested it in angular 5.2.0 and rxjs 5.5.2
None of the above answers worked for me but this does -- Use <P style='line-height: 8px;'>
to replace <p>
wherever needed (or put it in the style tag like <style>P {line-height: 8px;}</style>
to affect all <p>
tags). I realise Mauro says this, but if someone comes here for help, I expect they would want to see an example.
Your first example is effectively what you need:
<TextBlock Text="{Binding CelsiusTemp, StringFormat={}{0}°C}" />
You can do this the following two ways:
1) Using loop
attribute in video element (mentioned in the first answer):
2) and you can use the ended
media event:
window.addEventListener('load', function(){
var newVideo = document.getElementById('videoElementId');
newVideo.addEventListener('ended', function() {
this.currentTime = 0;
this.play();
}, false);
newVideo.play();
});
I was trying to achieve this but in the context of a MAVEN build. As part of my pom.xml
configuration, I had a reference to an environment variable as part of a path to a local JAR:
<dependency>
<groupId>the group id</groupId>
<artifactId>the artifact id</artifactId>
<version>the version</version>
<scope>system</scope>
<systemPath>${env.MY_ENV_VARIABLE}/the_local_jar_archive.jar</systemPath>
</dependency>
To compile my project, I had to define the environment variable as part of the run configuration for the maven build as explained by Max's answer. I was able to launch the maven compilation and the project would compile just fine.
However, as this environment variable involves some dependencies, the default "problems" view of Eclipse (where compilation errors/warnings usually show) would still show errors along the lines of Could not find artifact
and systemPath should be an absolute path but is ${env.MY_ENV_VARIABLE}/the_local_jar_archive.jar
.
How I fixed it
Go into Window -> Preferences -> General -> Worksapce -> Linked Resources
and define a new path variable.
Finally, in my case I just needed to Right click on my pom.xml
file, select Maven -> Update Project
and the errors disappeared from the "Problems" view.
I think this is what you want, from the bootstrap documentation "Horizontal form Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form. Doing so changes .form-groups to behave as grid rows, so no need for .row". So:
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>
I know this question is already solved.. but there is a very easy way to crop. you can just do it in one line-
Mat cropedImage = fullImage(Rect(X,Y,Width,Height));
I was able to draw a separator with flexbox
properties even with a text in the center of line.
<View style={{flexDirection: 'row', alignItems: 'center'}}>
<View style={{flex: 1, height: 1, backgroundColor: 'black'}} />
<View>
<Text style={{width: 50, textAlign: 'center'}}>Hello</Text>
</View>
<View style={{flex: 1, height: 1, backgroundColor: 'black'}} />
</View>
It seems to me that the answers here are outdated. For me under Windows 10 and Git 2.15.0 this did the job:
git credential reject
protocol=https
host=github.com
<Empty line here>
And then to set the new username & password:
git credential fill
protocol=https
host=github.com
<empty line here>
After this, if the credentials now work on the desired target host, we should use git credential approve
-as mentioned in typical use of Git credentials (step 4)- to tell the credential helpers to mark the credentials as approved and reuse them in future connections.
dummyElem.focus() where dummyElem is a hidden object (e.g. has negative zIndex)?
? extends HasWord
means "A class/interface that extends HasWord
." In other words, HasWord
itself or any of its children... basically anything that would work with instanceof HasWord
plus null
.
In more technical terms, ? extends HasWord
is a bounded wildcard, covered in Item 31 of Effective Java 3rd Edition, starting on page 139. The same chapter from the 2nd Edition is available online as a PDF; the part on bounded wildcards is Item 28 starting on page 134.
Update: PDF link was updated since Oracle removed it a while back. It now points to the copy hosted by the Queen Mary University of London's School of Electronic Engineering and Computer Science.
Update 2: Lets go into a bit more detail as to why you'd want to use wildcards.
If you declare a method whose signature expect you to pass in List<HasWord>
, then the only thing you can pass in is a List<HasWord>
.
However, if said signature was List<? extends HasWord>
then you could pass in a List<ChildOfHasWord>
instead.
Note that there is a subtle difference between List<? extends HasWord>
and List<? super HasWord>
. As Joshua Bloch put it: PECS = producer-extends, consumer-super.
What this means is that if you are passing in a collection that your method pulls data out from (i.e. the collection is producing elements for your method to use), you should use extends
. If you're passing in a collection that your method adds data to (i.e. the collection is consuming elements your method creates), it should use super
.
This may sound confusing. However, you can see it in List
's sort
command (which is just a shortcut to the two-arg version of Collections.sort). Instead of taking a Comparator<T>
, it actually takes a Comparator<? super T>
. In this case, the Comparator is consuming the elements of the List
in order to reorder the List itself.
You can download a JSON parser from a link on the JSON.org website which works great, you can also stringify you JSON to view the contents.
Also, if you're using EVAL and it's a JSON array then you'll need to use the following synrax:
eval('([' + jsonData + '])');
For Angular >2 , You can pass null to all the params you want to clear
this.router.navigate(['/yourRoute'], {queryParams:{params1: null, param2: null}})
That is a very interesting question.
On the Lang.Next conference there was a very interesting discussion about this topic, in which authors of several programming languages participate (Scala, Dart, C#). There was not a clear consensus at the end, but from my point of view there is one message:
The ideal language for this "cloud age" should be object oriented (because that is how we understand and are able to model the world) and also embrace functional programming.
The code in "cloud age" is almost always distributed: running on several cores/machines (in the cloud center) or just the client/server separation. And it is also asynchronous. We do not block the code when waiting for WS response. The callbacks come in any time.
When using standard imperative programming languages, handling the asynchrony and the distribution really complicated. You have to always take care of the "current state" and when the callbacks come in, you have to decide what to do, in dependences of this state.
Functional programming helps to eliminate the "state" and is much better suited for this new situation.
So I would say: In cloud computing the code is distributed, state-less, asynchronous. Functional programming can help you with that. Object oriented is almost a must to be able to model the world.
I have wrote a blog post about it, if you are interested. I like C#, but actually I would say Scala, Clojure, F# might fit even better.
On the other hand C++ will always be there, and lately is being modernized and getting more attention.
I suggest next solution for capturing any current active window (not only our C# application) or entire screen with cursor position determination relative to left-top corner of window or screen respectively:
public enum enmScreenCaptureMode
{
Screen,
Window
}
class ScreenCapturer
{
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
private static extern IntPtr GetWindowRect(IntPtr hWnd, ref Rect rect);
[StructLayout(LayoutKind.Sequential)]
private struct Rect
{
public int Left;
public int Top;
public int Right;
public int Bottom;
}
public Bitmap Capture(enmScreenCaptureMode screenCaptureMode = enmScreenCaptureMode.Window)
{
Rectangle bounds;
if (screenCaptureMode == enmScreenCaptureMode.Screen)
{
bounds = Screen.GetBounds(Point.Empty);
CursorPosition = Cursor.Position;
}
else
{
var foregroundWindowsHandle = GetForegroundWindow();
var rect = new Rect();
GetWindowRect(foregroundWindowsHandle, ref rect);
bounds = new Rectangle(rect.Left, rect.Top, rect.Right - rect.Left, rect.Bottom - rect.Top);
CursorPosition = new Point(Cursor.Position.X - rect.Left, Cursor.Position.Y - rect.Top);
}
var result = new Bitmap(bounds.Width, bounds.Height);
using (var g = Graphics.FromImage(result))
{
g.CopyFromScreen(new Point(bounds.Left, bounds.Top), Point.Empty, bounds.Size);
}
return result;
}
public Point CursorPosition
{
get;
protected set;
}
}
You can do this via a couple ways.
One is when you run your application, you can pass it a flag.
java -Dgate.home="http://gate.ac.uk/wiki/code-repository" your_application
Or set it programmatically in code before the piece of code that needs this property set. Java keeps a Properties
object for System
wide configuration.
Properties props = System.getProperties();
props.setProperty("gate.home", "http://gate.ac.uk/wiki/code-repository");

In the documentation of the version 4.11.x, says: ` "This method is like _.sortBy except that it allows specifying the sort orders of the iteratees to sort by. If orders is unspecified, all values are sorted in ascending order. Otherwise, specify an order of "desc" for descending or "asc" for ascending sort order of corresponding values." (source https://lodash.com/docs/4.17.10#orderBy)
let sorted = _.orderBy(this.items, ['fieldFoo', 'fieldBar'], ['asc', 'desc'])
Try this Bash syntax instead of trying to use an external program expr
:
count=$((FIRSTV-SECONDV))
BTW, the correct syntax of using expr
is:
count=$(expr $FIRSTV - $SECONDV)
But keep in mind using expr
is going to be slower than the internal Bash syntax I provided above.

instead of Row(max(reference_week)=datetime.date(2020, 6, 26))
Your website is blank because ROOT directory is missing from your ../webapps
folder. Refer to tomcat documentation for the specific location on where it should be.
I do the following:
from selenium import webdriver
browser = webdriver.Chrome('C:\chromedriver.exe')
browser.maximize_window()
Method Object JComboBox.getSelectedItem()
returns a value that is wrapped by Object
type so you have to cast it accordingly.
Syntax:
YourType varName = (YourType)comboBox.getSelectedItem();`
String value = comboBox.getSelectedItem().toString();
See this question for some discussion.
They recommend the articles: Exploring the C++ Unit Testing Framework Jungle, By Noel Llopis. And the more recent: C++ Test Unit Frameworks
I have not found an article that compares googletest to the other frameworks yet.
Below code checks whether a given set is a "proper subset" of another set
def is_proper_subset(set, superset):
return all(x in superset for x in set) and len(set)<len(superset)
You just need to set background and give previous.xml file in background of button in your layout file.
<Button
android:id="@+id/button1"
android:background="@drawable/previous"
android:layout_width="200dp"
android:layout_height="126dp"
android:text="Hello" />
and done.Edit Following is previous.xml file in drawable directory
<?xml version="1.0" encoding="utf-8"?>
<item android:drawable="@drawable/onclick" android:state_selected="true"></item>
<item android:drawable="@drawable/onclick" android:state_pressed="true"></item>
<item android:drawable="@drawable/normal"></item>
You can access the fields by indexing the object array:
foreach (object[] item in selectedValues)
{
idTextBox.Text = item[0];
titleTextBox.Text = item[1];
contentTextBox.Text = item[2];
}
That said, you'd be better off storing the fields in a small class of your own if the number of items is not dynamic:
public class MyObject
{
public int Id { get; set; }
public string Title { get; set; }
public string Content { get; set; }
}
Then you can do:
foreach (MyObject item in selectedValues)
{
idTextBox.Text = item.Id;
titleTextBox.Text = item.Title;
contentTextBox.Text = item.Content;
}
Depending on the size and number of files being copied, you could copy the destination directory over the source first with "yes to all", then do the original copy you were doing, also with "yes to all" set. That should give you the same results.
I tried the answer by Sibeesh Venu, but that didn't work for me. I believe that if I had killed all chrome processes, it would have worked. I completed some other testing and found that turning off "Continue where you left off" in Chrome settings ensured that this did not occur again for me.
If you are sure you want to remove all commit history, simply delete the .git
directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:
git init
git remote add origin [email protected]:user/repo
now commit your current version of code
git add *
git commit -am 'message'
and finally force the update to GitHub:
git push -f origin master
However, I suggest backing up the history (the .git
folder in the repository) before taking these steps!

Below is my code to get a picture to load into a PictureBox and Display a Picture name in to a TextBox without Extension.
private void browse_btn_Click(object sender, EventArgs e)
{
OpenFileDialog Open = new OpenFileDialog();
Open.Filter = "image files|*.jpg;*.png;*.gif;*.icon;.*;";
if (Open.ShowDialog() == DialogResult.OK)
{
imageLocation = Open.FileName.ToString();
string picTureName = null;
picTureName = Path.ChangeExtension(Path.GetFileName(imageLocation), null);
pictureBox_Gift.ImageLocation = imageLocation;
GiftName_txt.Text = picTureName.ToString();
Savebtn.Enabled = true;
}
}

These two header values can be combined to get the required effect on both IE and Firefox
I answered a similar question here
As @Syden said, the mixins will work. Another option is using SASS map-get
like this..
@media (min-width: map-get($grid-breakpoints, sm)){
.something {
padding: 10px;
}
}
@media (min-width: map-get($grid-breakpoints, md)){
.something {
padding: 20px;
}
}

NOW() is the replacement of Oracle Sysdate in Postgres.
Try "Select now()", it will give you the system timestamp.
In case you are working with a column with string values, you can use THE VERY USEFUL function series.str.isnumeric() like:
a = pd.Series(['hi','hola','2.31','288','312','1312', '0,21', '0.23'])
What i do is to copy that column to new column, and do a str.replace('.','') and str.replace(',','') then i select the numeric values. and:
a = a.str.replace('.','')
a = a.str.replace(',','')
a.str.isnumeric()
Out[15]: 0 False 1 False 2 True 3 True 4 True 5 True 6 True 7 True dtype: bool
Good luck all!
Your reference to "0x31 = 1" makes me think you're actually trying to convert ASCII values to strings - in which case you should be using something like Encoding.ASCII.GetString(Byte[])
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same time
