For celery 3.0+:
$ celery purge
To purge a specific queue:
$ celery -Q queue_name purge
I created this function that allows to enter a string and returns a list of string trimmed by any character
func Trim(input:String, character:Character)-> [String]
{
var collection:[String] = [String]()
var index = 0
var copy = input
let iterable = input
var trim = input.startIndex.advancedBy(index)
for i in iterable.characters
{
if (i == character)
{
trim = input.startIndex.advancedBy(index)
// apennding to the list
collection.append(copy.substringToIndex(trim))
//cut the input
index += 1
trim = input.startIndex.advancedBy(index)
copy = copy.substringFromIndex(trim)
index = 0
}
else
{
index += 1
}
}
collection.append(copy)
return collection
}
as didn't found a way to do this in swift (compiles and work perfectly in swift 2.0)
What about iterating on the /proc virtual file system ? http://linux.die.net/man/5/proc ?
A cleaner way is to set connectionString in xml file, for example Web.Confing(WepApplication)
or App.Config(StandAloneApplication)
.
<connectionStrings>
<remove name="myConn"/>
<add name="myConn" connectionString="User ID=sa;Password=XXXXX;Initial Catalog=qualitaBorri;Data Source=PC_NAME\SQLEXPRESS;Connection Timeout=60"/>
</connectionStrings>
By code you can get connection in this way:
public static SqlConnection getConnection()
{
string conn = string.Empty;
conn = System.Configuration.ConfigurationManager.ConnectionStrings["myConn"].ConnectionString;
SqlConnection aConnection = new SqlConnection(conn);
return aConnection;
}
You can set ConnectionTimeout
only you create a instance.
When instance is create you don't change this value.
In my case it was from "Automatic Backlink Checker" extension. Maybe this will help some other users to fix their problem easier. I went from disabling all of the extensions at once to disabling them one by one. This way the mole.

Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?
Interface does not implement the methods of another interface but just extends them.
One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward
and moveBack
but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp
, moveDown
so
in the end you have:
public interface IVehicle {
bool moveForward(int x);
bool moveBack(int x);
};
and airplane:
public interface IAirplane extends IVehicle {
bool moveDown(int x);
bool moveUp(int x);
};
Your syntax is incorrect. The var
keyword in your for
loop must be followed by a variable name, in this case its propName
var propValue;
for(var propName in nyc) {
propValue = nyc[propName]
console.log(propName,propValue);
}
I suggest you have a look here for some basics:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in
The reason why your code doesn't work is because $watch
by default does reference check. So in a nutshell it make sure that the object which is passed to it is new object. But in your case you are just modifying some property of form object not creating a new one. In order to make it work you can pass true
as the third parameter.
$scope.$watch('form', function(newVal, oldVal){
console.log('invoked');
}, true);
It will work but You can use $watchCollection which will be more efficient then $watch because $watchCollection
will watch for shallow properties on form object. E.g.
$scope.$watchCollection('form', function (newVal, oldVal) {
console.log(newVal, oldVal);
});
For me, and other newbies who has just contacted with Javascript,
I think that the Closeure Solution
is a little kind of too confusing.
While I found that, you can easilly pass as many parameters as you want to every ajax callback using jquery.
Here are two easier solutions.
First one, which @zeroasterisk has mentioned above, example:
var $items = $('.some_class');
$.each($items, function(key, item){
var url = 'http://request_with_params' + $(item).html();
$.ajax({
selfDom : $(item),
selfData : 'here is my self defined data',
url : url,
dataType : 'json',
success : function(data, code, jqXHR){
// in $.ajax callbacks,
// [this] keyword references to the options you gived to $.ajax
// if you had not specified the context of $.ajax callbacks.
// see http://api.jquery.com/jquery.ajax/#jQuery-ajax-settings context
var $item = this.selfDom;
var selfdata = this.selfData;
$item.html( selfdata );
...
}
});
});
Second one, pass self-defined-datas by adding them into the XHR object
which exists in the whole ajax-request-response life span.
var $items = $('.some_class');
$.each($items, function(key, item){
var url = 'http://request_with_params' + $(item).html();
$.ajax({
url : url,
dataType : 'json',
beforeSend : function(XHR) {
// ??????,???? jquery??????? XHR
XHR.selfDom = $(item);
XHR.selfData = 'here is my self defined data';
},
success : function(data, code, jqXHR){
// jqXHR is a superset of the browser's native XHR object
var $item = jqXHR.selfDom;
var selfdata = jqXHR.selfData;
$item.html( selfdata );
...
}
});
});
As you can see these two solutions has a drawback that : you need write a little more code every time than just write:
$.get/post (url, data, successHandler);

I assume you are talking about real push notifications that can be delivered even when the user is not surfing your website (otherwise check out WebSockets or legacy methods like long polling).
Can we use GCM/APNS to send push notification to all Web Browsers including Firefox & Safari?
GCM is only for Chrome and APNs is only for Safari. Each browser manufacturer offers its own service.
If not via GCM can we have our own back-end to do the same?
The Push API requires two backends! One is offered by the browser manufacturer and is responsible for delivering the notification to the device. The other one should be yours (or you can use a third party service like Pushpad) and is responsible for triggering the notification and contacting the browser manufacturer's service (i.e. GCM, APNs, Mozilla push servers).
Disclosure: I am the Pushpad founder
I had the same error on my Angular6 project. none of those solutions seemed to work out for me. turned out that the problem was due to an element which was specified as dropdown
but it didn't have dropdown options in it. take a look at code below:
<span class="nav-link" id="navbarDropdownMenuLink" data-toggle="dropdown"
aria-haspopup="true" aria-expanded="false">
<i class="material-icons "
style="font-size: 2rem">notifications</i>
<span class="notification"></span>
<p>
<span class="d-lg-none d-md-block">Some Actions</span>
</p>
</span>
<div class="dropdown-menu dropdown-menu-left"
*ngIf="global.localStorageItem('isInSadHich')"
aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">You have 5 new tasks</a>
<a class="dropdown-item" href="#">You're now friend with Andrew</a>
<a class="dropdown-item" href="#">Another Notification</a>
<a class="dropdown-item" href="#">Another One</a>
</div>
removing the code data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"
solved the problem.
I myself think that by each click on the first span element, the scope expected to set style for dropdown children which did not existed in the parent span, so it threw error.
$('input.myclass[type=checkbox]').each(function () {
var sThisVal = (this.checked ? $(this).val() : ""); });
First approach is better IMHO:
Besides the HttpClient logging described in the other answer, you can also introduce a ClientHttpRequestInterceptor that reads the body of the request and the response and logs it. You might want to do this if other stuff also uses the HttpClient, or if you want a custom logging format. Caution: you will want to give the RestTemplate a BufferingClientHttpRequestFactory such that you can read the response twice.
Format as JSON (you can "beautify" in IDE later):
local function format_any_value(obj, buffer)
local _type = type(obj)
if _type == "table" then
buffer[#buffer + 1] = '{"'
for key, value in next, obj, nil do
buffer[#buffer + 1] = tostring(key) .. '":'
format_any_value(value, buffer)
buffer[#buffer + 1] = ',"'
end
buffer[#buffer] = '}' -- note the overwrite
elseif _type == "string" then
buffer[#buffer + 1] = '"' .. obj .. '"'
elseif _type == "boolean" or _type == "number" then
buffer[#buffer + 1] = tostring(obj)
else
buffer[#buffer + 1] = '"???' .. _type .. '???"'
end
end
Usage:
local function format_as_json(obj)
if obj == nil then return "null" else
local buffer = {}
format_any_value(obj, buffer)
return table.concat(buffer)
end
end
local function print_as_json(obj)
print(_format_as_json(obj))
end
print_as_json {1, 2, 3}
print_as_json(nil)
print_as_json("string")
print_as_json {[1] = 1, [2] = 2, three = { { true } }, four = "four"}
BTW, I also wrote several other solutions: a very fast one, and one with special characters escaping: https://github.com/vn971/fast_json_encode
I know is too late, but for somebody whit the same need editText.setFocusable(false) si what you are looking for.
There's a much simpler way to convert your XmlDocument to a string; use the OuterXml property. The OuterXml property returns a string version of the xml.
public string GetXMLAsString(XmlDocument myxml)
{
return myxml.OuterXml;
}
You could try some sort of COALESCE trick, eg:
SELECT COALESCE( CASE WHEN condition1 THEN calculation1 ELSE NULL END, CASE WHEN condition2 THEN calculation2 ELSE NULL END, etc... )
It means 'not equal to'. So you're filtering out records where ordid
is 605. Overall you're looking for any records which have the same prodid
and qty
values as those assigned to ordid
605, but which are for a different order.
Actually AllocConsole with SetStdHandle in a GUI application might be a safer approach. The problem with the "console hijacking" already mentioned, is that the console might not be a foreground window at all, (esp. considering the influx of new window managers in Vista/Windows 7) among other things.
Just to add my configuration to the mix, I'm using MySQL 5.7.8 which has the same strict sql_mode rules by default.
I finally figured the following working in my /etc/mysql/my.conf:
[mysqld]
sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"
i.e. dash, not underscore and quotes around the value.
I have NO other my.conf files other than /etc/mysql/my.conf
There are some extra config includes being loaded from /etc/mysql/conf.d/ but they are blank.
And that seems to work for me.
I have this code:
<html>_x000D_
<head>_x000D_
<SCRIPT type=text/javascript>_x000D_
function deshabilitarBoton() { _x000D_
document.getElementById("boton").style.display = 'none';_x000D_
document.getElementById("envio").innerHTML ="<br><img src='img/loading.gif' width='16' height='16' border='0'>Generando..."; _x000D_
return true;_x000D_
} _x000D_
</SCRIPT>_x000D_
<title>untitled</title>_x000D_
</head>_x000D_
<body>_x000D_
<form name="form" action="ok.do" method="post" >_x000D_
<table>_x000D_
<tr>_x000D_
<td>Fecha inicio:</td>_x000D_
<td><input type="TEXT" name="fecha_inicio" id="fecha_inicio" /></td>_x000D_
</tr>_x000D_
</table>_x000D_
<div id="boton">_x000D_
<input type="submit" name="event" value="Enviar" class="button" onclick="return deshabilitarBoton()" />_x000D_
</div>_x000D_
<div id="envio">_x000D_
</div>_x000D_
</form>_x000D_
</body>_x000D_
</html>
_x000D_
This worked for me,
echo > file.extension
Here's another way I found today, got ideas from other answers but it worked
sometext > filename.extension
Eg.
xyz > emptyfile.txt //this would create an empty zero byte text file
abc > filename.mp4 //this would create an zero byte MP4 video media file
This would show an error message in the command prompt that ,
xyz
is not as an internal or external command, operable program or batch file.
But the weird thing I found was the file is being created in the directory even if the command is not a standard windows command.
When you are not sure of the number of rows, then you can do it this way:
followers_df.index = range(len(followers_df))
Technically, to repair your statement, you can add LIMIT 1
to the subquery to ensure that at most 1 row is returned. That would remove the error, your code would still be nonsense.
... 'SELECT store_key FROM store LIMIT 1' ...
Practically, you want to match rows somehow instead of picking an arbitrary row from the remote table store
to update every row of your local table customer
.
Your rudimentary question doesn't provide enough details, so I am assuming a text column match_name
in both tables (and UNIQUE
in store
) for the sake of this example:
... 'SELECT store_key FROM store
WHERE match_name = ' || quote_literal(customer.match_name) ...
But that's an extremely expensive way of doing things.
Ideally, you should completely rewrite the statement.
UPDATE customer c
SET customer_id = s.store_key
FROM dblink('port=5432, dbname=SERVER1 user=postgres password=309245'
,'SELECT match_name, store_key FROM store')
AS s(match_name text, store_key integer)
WHERE c.match_name = s.match_name
AND c.customer_id IS DISTINCT FROM s.store_key;
This remedies a number of problems in your original statement.
Obviously, the basic problem leading to your error is fixed.
It's almost always better to join in additional relations in the FROM
clause of an UPDATE
statement than to run correlated subqueries for every individual row.
When using dblink, the above becomes a thousand times more important. You do not want to call dblink()
for every single row, that's extremely expensive. Call it once to retrieve all rows you need.
With correlated subqueries, if no row is found in the subquery, the column gets updated to NULL, which is almost always not what you want.
In my updated form, the row only gets updated if a matching row is found. Else, the row is not touched.
Normally, you wouldn't want to update rows, when nothing actually changes. That's expensively doing nothing (but still produces dead rows). The last expression in the WHERE
clause prevents such empty updates:
AND c.customer_id IS DISTINCT FROM sub.store_key
You can replace your old dictionary with a defaultdict
:
>>> from collections import defaultdict
>>> d = {'foo': 123, 'bar': 456}
>>> d['baz']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 'baz'
>>> d = defaultdict(lambda: -1, d)
>>> d['baz']
-1
The "trick" here is that a defaultdict
can be initialized with another dict
. This means
that you preserve the existing values in your normal dict
:
>>> d['foo']
123
while ((line = stringReader.ReadLine()) != null)
{
// split the lines
for (int c = 0; c < line.Length; c++)
{
line = line.Replace("\\", "");
lineBreakOne = line.Substring(1, c - 2);
lineBreakTwo = line.Substring(c + 2, line.Length - 2);
}
}
This might work:
public int binaryToInteger(String binary) {
char[] numbers = binary.toCharArray();
int result = 0;
for(int i=numbers.length - 1; i>=0; i--)
if(numbers[i]=='1')
result += Math.pow(2, (numbers.length-i - 1));
return result;
}
Delegate
is just the base class so you can't use it like that. You could do something like this though:
public void DoRequest(string request, Action<string> callback)
{
// do stuff....
callback("asdf");
}
I had issues getting the above code to work within cookie.js. The following code managed to create the correct timestamp for the cookie expiration in my instance.
var inFifteenMinutes = new Date(new Date().getTime() + 15 * 60 * 1000);
This was from the FAQs for Cookie.js
I think the most elegant way to do that is to use the javascript Object.keys
like this (I had first implemented a pipe for that but for me, it just complicated my work unnecessary):
in the Component pass Object to template:
Object = Object;
then in the template:
<div *ngFor="let key of Object.keys(objs)">
my key: {{key}}
my object {{objs[key] | json}} <!-- hier I could use ngFor again with Object.keys(objs[key]) -->
</div>
If you have a lot of subobjects you should create a component that will print the object for you. By printing the values and keys as you want and on an subobject calling itselfe recursively.
Hier you can find an stackblitz demo for both methods.
Since Symfony 3.3 you can use binding, like
services:
_defaults:
autowire: true
autoconfigure: true
bind:
$kernelProjectDir: '%kernel.project_dir%'
After that you can use parameter $kernelProjectDir in any controller OR service. Just like
class SomeControllerOrService
{
public function someAction(...., $kernelProjectDir)
{
.....
WORKING SOLUTION
Let me add to this old post, a working solution I used to use that works in probably 80% or more of all browsers both new and old.
The solution is complex yet simple. The first step is to make use of CSS and guise the input file type with "under-elements" that show through as it has an opacity of 0. The next step is to use JavaScript to update its label as needed.
HTML The ID's are simply inserted if you wanted a quick way to access a specific element, the classes however, are a must as they relate to the CSS that sets this whole process up
<div class="file-input wrapper">
<input id="inpFile0" type="file" class="file-input control" />
<div class="file-input content">
<label id="inpFileOutput0" for="inpFileButton" class="file-input output">Click Here</label>
<input id="inpFileButton0" type="button" class="file-input button" value="Select File" />
</div>
</div>
CSS Keep in mind, coloring and font-styles and such are totally your preference, if you use this basic CSS, you can always use after-end mark up to style as you please, this is shown in the jsFiddle listed at the end.
.file-test-area {
border: 1px solid;
margin: .5em;
padding: 1em;
}
.file-input {
cursor: pointer !important;
}
.file-input * {
cursor: pointer !important;
display: inline-block;
}
.file-input.wrapper {
display: inline-block;
font-size: 14px;
height: auto;
overflow: hidden;
position: relative;
width: auto;
}
.file-input.control {
-moz-opacity:0 ;
filter:alpha(opacity: 0);
opacity: 0;
height: 100%;
position: absolute;
text-align: right;
width: 100%;
z-index: 2;
}
.file-input.content {
position: relative;
top: 0px;
left: 0px;
z-index: 1;
}
.file-input.output {
background-color: #FFC;
font-size: .8em;
padding: .2em .2em .2em .4em;
text-align: center;
width: 10em;
}
.file-input.button {
border: none;
font-weight: bold;
margin-left: .25em;
padding: 0 .25em;
}
JavaScript Pure and true, however, some OLDER (retired) browsers may still have trouble with it (like Netscrape 2!)
var inp = document.getElementsByTagName('input');
for (var i=0;i<inp.length;i++) {
if (inp[i].type != 'file') continue;
inp[i].relatedElement = inp[i].parentNode.getElementsByTagName('label')[0];
inp[i].onchange /*= inp[i].onmouseout*/ = function () {
this.relatedElement.innerHTML = this.value;
};
};
As others said, class variables are shared between a given class and its subclasses. Class instance variables belong to exactly one class; its subclasses are separate.
Why does this behavior exist? Well, everything in Ruby is an object—even classes. That means that each class has an object of the class Class
(or rather, a subclass of Class
) corresponding to it. (When you say class Foo
, you're really declaring a constant Foo
and assigning a class object to it.) And every Ruby object can have instance variables, so class objects can have instance variables, too.
The trouble is, instance variables on class objects don't really behave the way you usually want class variables to behave. You usually want a class variable defined in a superclass to be shared with its subclasses, but that's not how instance variables work—the subclass has its own class object, and that class object has its own instance variables. So they introduced separate class variables with the behavior you're more likely to want.
In other words, class instance variables are sort of an accident of Ruby's design. You probably shouldn't use them unless you specifically know they're what you're looking for.
The common practice is using @class in header files (but you still need to #import the superclass), and #import in implementation files. This will avoid any circular inclusions, and it just works.
The advantage of the conditional operator is that it is an operator. In other words, it returns a value. Since if
is a statement, it cannot return a value.
There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.
Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.
"Allocation Failure" is a cause of GC cycle to kick in.
"Allocation Failure" means that no more space left in Eden to allocate object. So, it is normal cause of young GC.
Older JVM were not printing GC cause for minor GC cycles.
"Allocation Failure" is almost only possible cause for minor GC. Another reason for minor GC to kick could be CMS remark phase (if +XX:+ScavengeBeforeRemark
is enabled).
sprintf can do this:
#include <stdio.h>
int main() {
float w = 234.567;
char x[__SIZEOF_FLOAT__];
sprintf(x, "%g", w);
puts(x);
}
Note: This will completely remove nodejs from your system; then you can make a fresh install from the below commands.
Removing Nodejs and Npm
sudo apt-get remove nodejs npm node
sudo apt-get purge nodejs
Now remove .node
and .npm
folders from your system
sudo rm -rf /usr/local/bin/npm
sudo rm -rf /usr/local/share/man/man1/node*
sudo rm -rf /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm -rf /opt/local/bin/node
sudo rm -rf opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*
Go to home directory and remove any node or node_modules
directory, if exists.
You can verify your uninstallation by these commands; they should not output anything.
which node
which nodejs
which npm
Installing NVM (Node Version Manager) by downloading and running a script
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
The command above will clone the NVM repository from Github to the ~/.nvm
directory:
Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
As the output above says, you should either close and reopen the terminal or run the commands to add the path to nvm script to the current shell session. You can do whatever is easier for you.
Once the script is in your PATH, verify that nvm was properly installed by typing:
nvm --version
which should give this output:
0.34.0
Installing Node.js and npm
nvm install node
nvm install --lts
Once the installation is completed, verify it by printing the Node.js version:
node --version
should give this output:
v12.8.1
Npm should also be installed with node, verify it using
npm -v
should give:
6.13.4
Extra - [Optional] You can also use two different versions of node using nvm easily
nvm install 8.10.0 # just put the node version number Now switch between node versions
$ nvm ls
-> v12.14.1
v13.7.0
default -> lts/* (-> v12.14.1)
node -> stable (-> v13.7.0) (default)
stable -> 13.7 (-> v13.7.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.14.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.18.1 (-> N/A)
In my case v12.14.1 and v13.7.0 both are installed, to switch I have to just use
nvm use 12.14.1
Configuring npm for global installations In your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a ~/.profile
file if does not exist and add this line:
PATH="$HOME/.npm-global/bin:$PATH"
On the command line, update your system variables:
source ~/.profile
That's all

This is what worked for me (ScrollView
(optional) so more content can be added if needed, plus centered content):
import SwiftUI
struct SomeView: View {
var body: some View {
GeometryReader { geometry in
ScrollView(Axis.Set.horizontal) {
HStack(alignment: .center) {
ForEach(0..<8) { _ in
Text("")
}
}.frame(width: geometry.size.width, height: 50)
}
}
}
}
// MARK: - Preview
#if DEBUG
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
#endif
Result
since strings data types have variable length, it is by default stored as object dtype. If you want to store them as string type, you can do something like this.
df['column'] = df['column'].astype('|S80') #where the max length is set at 80 bytes,
or alternatively
df['column'] = df['column'].astype('|S') # which will by default set the length to the max len it encounters
In Excel 2007 onwards, you can use the much simpler code using a more precise reference:
dim pvt as PivotTable
dim pvtField as PivotField
set pvt = ActiveSheet.PivotTables("PivotTable2")
set pvtField = pvt.PivotFields("SavedFamilyCode")
pvtField.PivotFilters.Add xlCaptionEquals, Value1:= "K123223"

}
you can also use
$result = curl_exec($ch);
return response()->json(json_decode($result));
RHEL: /etc/pki/tls/openssl.cnf
Perhaps you can use something like Gaussian Mixture Models. Here's a Python package for doing GMMs (just did a Google search) http://www.ar.media.kyoto-u.ac.jp/members/david/softwares/em/
In addition to the angular json
filter already mentioned, there is also the angular toJson()
function.
angular.toJson(obj, pretty);
The second param of this function lets you switch on pretty printing and set the number of spaces to use.
If set to true, the JSON output will contain newlines and whitespace. If set to an integer, the JSON output will contain that many spaces per indentation.
(default: 2)
"Better" is subjective.
querySelector
is the newer feature.
getElementById
is better supported than querySelector
.
querySelector
is better supported than getElementsByClassName
.
querySelector
lets you find elements with rules that can't be expressed with getElementById
and getElementsByClassName
You need to pick the appropriate tool for any given task.
(In the above, for querySelector
read querySelector
/ querySelectorAll
).
This is what you need in the CSS:
html, body {
height: 100%;
width: 100%;
margin: 0;
}
You can solve this fully in the html:
<div>
<input ng-model=collapse type=checkbox>Title
<div ng-show=collapse>
Only shown when checkbox is clicked
</div>
</div>
This also works well with ng-repeat since it will create a local scope for each member.
<table>
<tbody ng-repeat='m in members'>
<tr>
<td><input type=checkbox ng-model=collapse></td>
<td>{{m.title}}</td>
</tr>
<tr ng-show=collapse>
<td> </td>
<td>{{ m.content }}</td>
</tr>
</tbody>
</table>
Be aware that even though a repeat has its own scope, initially it will inherit the value from collapse from super scopes. This allows you to set the initial value in one place but it can be surprising.
You can of course restyle the checkbox. See http://jsfiddle.net/azD5m/5/
Updated fiddle: http://jsfiddle.net/azD5m/374/ Original fiddle used closing </input>
tags to add the HTML text label instead of using <label>
tags.
For the Collatz problem, you can get a significant boost in performance by caching the "tails". This is a time/memory trade-off. See: memoization (https://en.wikipedia.org/wiki/Memoization). You could also look into dynamic programming solutions for other time/memory trade-offs.
Example python implementation:
import sys
inner_loop = 0
def collatz_sequence(N, cache):
global inner_loop
l = [ ]
stop = False
n = N
tails = [ ]
while not stop:
inner_loop += 1
tmp = n
l.append(n)
if n <= 1:
stop = True
elif n in cache:
stop = True
elif n % 2:
n = 3*n + 1
else:
n = n // 2
tails.append((tmp, len(l)))
for key, offset in tails:
if not key in cache:
cache[key] = l[offset:]
return l
def gen_sequence(l, cache):
for elem in l:
yield elem
if elem in cache:
yield from gen_sequence(cache[elem], cache)
raise StopIteration
if __name__ == "__main__":
le_cache = {}
for n in range(1, 4711, 5):
l = collatz_sequence(n, le_cache)
print("{}: {}".format(n, len(list(gen_sequence(l, le_cache)))))
print("inner_loop = {}".format(inner_loop))
Should you want to clear the array with something other than a value, std::file wont cut it; instead I found std::generate useful. e.g. I had a vector of lists I wanted to initialize
std::generate(v.begin(), v.end(), [] () { return std::list<X>(); });
You can do ints too e.g.
std::generate(v.begin(), v.end(), [n = 0] () mutable { return n++; });
or just
std::generate(v.begin(), v.end(), [] (){ return 0; });
but I imagine std::fill is faster for the simplest case
This Python script has GUI to select with explorer a Ipython Notebook you want to convert to pdf. The approach with wkhtmltopdf is the only approach I found works well and provides high quality pdfs. Other approaches described here are problematic, syntax highlighting does not work or graphs are messed up.
You'll need to install wkhtmltopdf: http://wkhtmltopdf.org/downloads.html
and Nbconvert
pip install nbconvert
# OR
conda install nbconvert

getResourceAsStream() look inside of your resource folder. So the fil shold be placed inside of the defined resource-folder i.e if the file reside in /src/main/resources/properties --> then the path should be /properties/yourFilename.
getClass.getResourceAsStream(/properties/yourFilename)
If I use the following query,
INSERT INTO xx_BLOB(ID,IMAGE)
VALUES(1,LOAD_FILE('E:/Images/xxx.png'));
Error: no such function: LOAD_FILE
You can also try this
string.Join(null,System.Text.RegularExpressions.Regex.Split(expr, "[^\\d]"));
First you need an object
public class MyObject {
public string Id {get;set;}
public string Text {get;set;}
...
}
Then in here
using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {
using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
JavaScriptSerializer js = new JavaScriptSerializer();
var objText = reader.ReadToEnd();
MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
}
}
I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.
JavaScriptSerializer System.Web.Script.Serialization
I also ran into the same problem, where the initial dtabase size is set to 4Gb and autogrowth is set by 1Mb. The virtual encrypted TrueCrypt drive that the databse was on, seemed to have plenty of space.
I changed a couple of (the above) things:
DBCC SHRINKDATABASE('...')
All to little avail (I could insert some more records, but soon ran into the same problem). The pagefile mentioned by Tobbi, made me try a larger virtual drive. (Even though my drive should not contain any such system files, since I run without it being mounted a lot of the time.)
When making this, I ran into a TrueCrypt-question, if I am going to store files larger than 4gb (as shown in this SuperUser question).
After these last two I was doing fine, and I am assuming this last one did the trick. I think TrueCrypt chooses an exfat file system (as described here), which limits all files to 4GB. (So I probably did not need to enlarge the drive after all, but I did anyway.)
This is probably a very rare border case, but maybe it is of help to somebody.
Unlike in the case of Angular, in React.js you need to update the state manually. You can do something like this:
<input
className="form-control"
type="text" value={this.state.name}
id={'todoName' + this.props.id}
onChange={e => this.onTodoChange(e.target.value)}
/>
And then in the function:
onTodoChange(value){
this.setState({
name: value
});
}
Also, you can set the initial state in the constructor of the component:
constructor (props) {
super(props);
this.state = {
updatable: false,
name: props.name,
status: props.status
};
}
From iOS 7 there is an API and you can get (and set) the tint color with:
self.view.tintColor
Or if you need the CGColor:
self.view.tintColor.CGColor
I had success using .on() like so:
$('.leadtoscore').on('click', {event_type: 'shot'}, add_event);
Then inside the add_event
function you get access to 'shot' like this:
event.data.event_type
See the .on() documentation for more info, where they provide the following example:
function myHandler( event ) {
alert( event.data.foo );
}
$( "p" ).on( "click", { foo: "bar" }, myHandler );
Spend some time to make it working for me.
Requirement:

I found good online regex testing tool. Covered my regex with tests:
You might want to flatten the data within your controller:
function MyCtrl ($scope) {
$scope.myData = [[1,2,3], [4,5,6], [7,8,9]];
$scope.flattened = function () {
var flat = [];
$scope.myData.forEach(function (item) {
flat.concat(item);
}
return flat;
}
}
And then in the HTML:
<table>
<tbody>
<tr ng-repeat="item in flattened()"><td>{{item}}</td></tr>
</tbody>
</table>
Yes, you've downloaded and installed the Java Runtime Environment (JRE) instead of the Java Development Kit (JDK). The latter has the tools.jar, java.exe, javac.exe, etc.
we can easily stop the set interval by calling clear interval
var count = 0 , i = 5;
var vary = function intervalFunc() {
count++;
console.log(count);
console.log('hello boy');
if (count == 10) {
clearInterval(this);
}
}
setInterval(vary, 1500);

Add a border
to the regular item, the same color
as the background
, so that it cannot be seen. That way the item has a border: 1px
whether it is being hovered or not.
First off, run
npm init
...will ask you a few questions (read this first) about your project/package and then generate a package.json file for you.
Then, once you have a package.json file, use
npm install <pkg> --save
or
npm install <pkg> --save-dev
...to install a dependency and automatically append it to your package.json
's dependencies
list.
(Note: You may need to manually tweak the version ranges for your dependencies.)
Use a JSON parser, like JSON.NET
string json = "{ \"Atlantic/Canary\": \"GMT Standard Time\", \"Europe/Lisbon\": \"GMT Standard Time\", \"Antarctica/Mawson\": \"West Asia Standard Time\", \"Etc/GMT+3\": \"SA Eastern Standard Time\", \"Etc/GMT+2\": \"UTC-02\", \"Etc/GMT+1\": \"Cape Verde Standard Time\", \"Etc/GMT+7\": \"US Mountain Standard Time\", \"Etc/GMT+6\": \"Central America Standard Time\", \"Etc/GMT+5\": \"SA Pacific Standard Time\", \"Etc/GMT+4\": \"SA Western Standard Time\", \"Pacific/Wallis\": \"UTC+12\", \"Europe/Skopje\": \"Central European Standard Time\", \"America/Coral_Harbour\": \"SA Pacific Standard Time\", \"Asia/Dhaka\": \"Bangladesh Standard Time\", \"America/St_Lucia\": \"SA Western Standard Time\", \"Asia/Kashgar\": \"China Standard Time\", \"America/Phoenix\": \"US Mountain Standard Time\", \"Asia/Kuwait\": \"Arab Standard Time\" }";
var data = (JObject)JsonConvert.DeserializeObject(json);
string timeZone = data["Atlantic/Canary"].Value<string>();
Open up eclipse, go to "Help -> Install New Software". Enter:

Under the "Web, XML, Java EE and OSGi Enterprise Developmet" category, select "PHP Development Tools (PDT) SDK Feature 3.1.1.201209101312".
Use this:
Button loginBtn = view.findViewById(R.id.loginBtn);
loginBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

I think it's important to mention little difference between 'self' and 'static' in PHP as 'best answer' uses 'static' which can give confusing result to some people.
<?php
class X {
function getStatic() {
// gets THIS class of instance of object
// that extends class in which is definied function
return static::class;
}
function getSelf() {
// gets THIS class of class in which function is declared
return self::class;
}
}
class Y extends X {
}
class Z extends Y {
}
$x = new X();
$y = new Y();
$z = new Z();
echo 'X:' . $x->getStatic() . ', ' . $x->getSelf() .
', Y: ' . $y->getStatic() . ', ' . $y->getSelf() .
', Z: ' . $z->getStatic() . ', ' . $z->getSelf();
Results:
X: X, X
Y: Y, X
Z: Z, X
You can access your session variable like '<%= Session["VariableName"]%>'
the text in single quotes will give session value. 1)
<script>
var session ='<%= Session["VariableName"]%>'
</script>
2) you can take a hidden field and assign value at server;
hiddenfield.value= session["xyz"].tostring();
//and in script you access the hiddenfield like
alert(document.getElementbyId("hiddenfield").value);
GitHub is the entire site. Gists are a particular service offered on that site, namely code snippets akin to pastebin. However, everything is driven by git revision control, so gists also have complete revision histories.
When you use a code like this:
using (var rsa = new RSACryptoServiceProvider(1024))
{
// Do something with the key...
// Encrypt, export, etc.
}
.NET (actually Windows) stores your key in a persistent key container forever. The container is randomly generated by .NET
This means:
Any random RSA/DSA key you have EVER generated for the purpose of protecting data, creating custom X.509 certificate, etc. may have been exposed without your awareness in the Windows file system. Accessible by anyone who has access to your account.
Your disk is being slowly filled with data. Normally not a big concern but it depends on your application (e.g. it might generates hundreds of keys every minute).
To resolve these issues:
using (var rsa = new RSACryptoServiceProvider(1024))
{
try
{
// Do something with the key...
// Encrypt, export, etc.
}
finally
{
rsa.PersistKeyInCsp = false;
}
}

Here is a solution that works with a dynamically defined type. The trick is creating the proper type of of array using Array.newInstance().
public static <T> List<T> fromJsonList(String json, Class<T> clazz) {
Object [] array = (Object[])java.lang.reflect.Array.newInstance(clazz, 0);
array = gson.fromJson(json, array.getClass());
List<T> list = new ArrayList<T>();
for (int i=0 ; i<array.length ; i++)
list.add(clazz.cast(array[i]));
return list;
}
Your code doesn't work for binary files because they can't be cast to strings in the data event handler. If you need to manipulate binary files you'll need to use a buffer. Sorry, I do not have an example of using a buffer because in my case I needed to manipulate HTML files. I just check the content type and then for text/html files update them as needed:
app.get('/*', function(clientRequest, clientResponse) {
var options = {
hostname: 'google.com',
port: 80,
path: clientRequest.url,
method: 'GET'
};
var googleRequest = http.request(options, function(googleResponse) {
var body = '';
if (String(googleResponse.headers['content-type']).indexOf('text/html') !== -1) {
googleResponse.on('data', function(chunk) {
body += chunk;
});
googleResponse.on('end', function() {
// Make changes to HTML files when they're done being read.
body = body.replace(/google.com/gi, host + ':' + port);
body = body.replace(
/<\/body>/,
'<script src="http://localhost:3000/new-script.js" type="text/javascript"></script></body>'
);
clientResponse.writeHead(googleResponse.statusCode, googleResponse.headers);
clientResponse.end(body);
});
}
else {
googleResponse.pipe(clientResponse, {
end: true
});
}
});
googleRequest.end();
});
Here's some mapping that could help:
:nnoremap <Leader>q" ciw""<Esc>P
:nnoremap <Leader>q' ciw''<Esc>P
:nnoremap <Leader>qd daW"=substitute(@@,"'\\\|\"","","g")<CR>P
If you haven't changed the mapleader variable, then activate the mapping with \q"
\q'
or \qd
. They add double quote around the word under the cursor, single quote around the word under the cursor, delete any quotes around the word under the cursor respectively.
input(char_val,current_date_format);
You can specify any date format at display time, like set char_val=date9.;
To prevent recopy the array every time which isn't efficient
What about using Stack
csharp> var i = new Stack<byte>();
csharp> i.Push(1);
csharp> i.Push(2);
csharp> i.Push(3);
csharp> i; { 3, 2, 1 }
csharp> foreach(var x in i) {
> Console.WriteLine(x);
> }
3 2 1
You can also do:
Integer a = '1182-2'.split('-')[0] as Integer
Integer b = '1182-2'.split('-')[1] as Integer
//a=1182 b=2
Here's a simple example:
public class ObservableClass
{
private Int32 _Value;
public Int32 Value
{
get { return _Value; }
set
{
if (_Value != value)
{
_Value = value;
OnValueChanged();
}
}
}
public event EventHandler ValueChanged;
protected void OnValueChanged()
{
if (ValueChanged != null)
ValueChanged(this, EventArgs.Empty);
}
}
public class ObserverClass
{
public ObserverClass(ObservableClass observable)
{
observable.ValueChanged += TheValueChanged;
}
private void TheValueChanged(Object sender, EventArgs e)
{
Console.Out.WriteLine("Value changed to " +
((ObservableClass)sender).Value);
}
}
public class Program
{
public static void Main()
{
ObservableClass observable = new ObservableClass();
ObserverClass observer = new ObserverClass(observable);
observable.Value = 10;
}
}
Note:
i think android studio has a 64bit kernel version which is giving the problem. https://github.com/swcarpentry/windows-installer/issues/49
Android fragment has some advantages and some disadvantages.
The most disadvantage of the fragment is that when you want to use a fragment you create it ones.
When you use it, onCreateView
of the fragment is called for each time. If you want to keep state of the components in the fragment you must save fragment state and yout must load its state in the next shown.
This make fragment view a bit slow and weird.
I have found a solution and I have used this solution: "Everything is great. Every body can try".
When first time onCreateView
is being run, create view as a global variable. When second time you call this fragment onCreateView
is called again you can return this global view. The fragment component state will be kept.
View view;
@Override
public View onCreateView(LayoutInflater inflater,
@Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
setActionBar(null);
if (view != null) {
if ((ViewGroup)view.getParent() != null)
((ViewGroup)view.getParent()).removeView(view);
return view;
}
view = inflater.inflate(R.layout.mylayout, container, false);
}
replot
This is another way to get multiple plots at once:
plot file1.data
replot file2.data
As a response to your question: "i want to reset all the data and keep last 30 days inside the table."
you can create an event. Check https://dev.mysql.com/doc/refman/5.7/en/event-scheduler.html
For example:
CREATE EVENT DeleteExpiredLog
ON SCHEDULE EVERY 1 DAY
DO
DELETE FROM log WHERE date < DATE_SUB(NOW(), INTERVAL 30 DAY);
Will run a daily cleanup in your table, keeping the last 30 days data available
The reader acts like a generator. On a file with some fake data:
>>> import sys, csv
>>> data = csv.reader(open('data.csv'),delimiter=';')
>>> data
<_csv.reader object at 0x1004a11a0>
>>> data.next()
['a', ' b', ' c']
>>> data.next()
['x', ' y', ' z']
>>> data.next()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration
Using operator.itemgetter as Ignacio suggests:
>>> data = csv.reader(open('data.csv'),delimiter=';')
>>> import operator
>>> sortedlist = sorted(data, key=operator.itemgetter(2), reverse=True)
>>> sortedlist
[['x', ' y', ' z'], ['a', ' b', ' c']]
You can always avoid fiddling around with the compiler by declaring the array as linear and doing the (row,col) to array index calculation by yourself.
static uint8_t l_matrix[200];
void test(int row, int col, uint8_t val)
{
uint8_t* matrix_ptr = l_matrix;
matrix_ptr [col+y*row] = val; // to assign a value

this is what the compiler would have done anyway.
Byte Stream - Stream is sequence of data. Input stream - reads data from source. Output stream - writes data to desitnation. Java Byte Streams are used to perform input/output byte by byte(8bits at a time). A byte stream is suitable for processing raw data like binary files. Java Character Streams are used to perform input/output 2 bytes at a time, because Characters are stored using Unicode conventions in Java with 2 bytes for each character. Character stream is useful when we process(read/write) text files.
RMI(Remote Method Invocation) - an API that provides a mechanism to create distributed application in java. The RMI allows an object to invoke methods on an object running in another JVM.
Both Serialization and Marshalling are loosely used as synonyms. Here are few differences.
Serialization - Data members of an object is written to binary form or Byte Stream(and then can be written in file/memory/database etc). No information about data-types can be retained once object data members are written to binary form.
Marshalling - Object is serialized(to byte stream in binary format) with data-type + Codebase attached and then passed Remote Object(RMI). Marshalling will transform the data-type into a predetermined naming convention so that it can be reconstructed with respect to the initial data-type.
So Serialization is part of Marshalling.
CodeBase is information that tells the receiver of Object where the implementation of this object can be found. Any program that thinks it might ever pass an object to another program that may not have seen it before must set the codebase, so that the receiver can know where to download the code from, if it doesn't have the code available locally. The receiver will, upon deserializing the object, fetch the codebase from it and load the code from that location. (Copied from @Nasir answer)
Serialization is almost like a stupid memory-dump of the memory used by the object(s), while Marshalling stores information about custom data-types.
In a way, Serialization performs marshalling with implematation of pass-by-value because no information of data-type is passed, just the primitive form is passed to byte stream.
Serialization may have some issues related to big-endian, small-endian if the stream is going from one OS to another if the different OS have different means of representing the same data. On the other hand, marshalling is perfectly fine to migrate between OS because the result is a higher-level representation.
I needed to specify min-height

display: flex
align-items: center
justify-content: center
min-height: 16em
To change the Path, you can set a new Path to an Enviroment-Variable named: VAGRANT_HOME
export VAGRANT_HOME=my/new/path/goes/here/
Thats maybe nice if you want to have those vagrant-Images on another HDD.

Since there is no full copy & paste solution yet, based on Joe Audette's answer:

public Startup(IWebHostEnvironment environment, IConfiguration configuration)
{
Environment = environment;

}
public void ConfigureServices(IServiceCollection services)
{
if (Environment.IsDevelopment())

Newer Edit: Lots of things have changed since this question was initially posted - there's a lot of really good information in wallacer's revised answer as well as VisioN's excellent breakdown
Edit: Just because this is the accepted answer; wallacer's answer is indeed much better:
return filename.split('.').pop();
My old answer:
return /[^.]+$/.exec(filename);
Should do it.
Edit: In response to PhiLho's comment, use something like:
return (/[.]/.exec(filename)) ? /[^.]+$/.exec(filename) : undefined;
To my knowledge, there is sadly no CSS filter to colorise an element (perhaps with the use of some SVG filter magic, but I'm somewhat unfamiliar with that) and even if that wasn't the case, filters are basically only supported by webkit browsers.
With that said, you could still work around this and use a canvas
to modify your image. Basically, you can draw an image element onto a canvas and then loop through the pixels, modifying the respective RGBA values to the colour you want.
However, canvases do come with some restrictions. Most importantly, you have to make sure that the image src comes from the same domain as the page. Otherwise the browser won't allow you to read or modify the pixel data of the canvas.
Here's a JSFiddle changing the colour of the JSFiddle logo.

I find req.protocol works when I am using express (have not tested without but I suspect it works). using current node 0.10.22 with express 3.4.3
app.use(function(req,res,next) {
if (!/https/.test(req.protocol)){
res.redirect("https://" + req.headers.host + req.url);
} else {
return next();
}
});
How about:
update table
set columnname = columnname + 1
where id = <some id>
CString s;
int i;
i = _wtoi(s); // if you use wide charater formats
i = _atoi(s); // otherwise
When it comes to implement a search functionality there are two suggested approach by official Android Developer Documentation.
You can either use a SearchDialog or a SearchWidget.
I am going to explain the implementation of Search functionality using SearchWidget.
I will explain search functionality in a RecyclerView using SearchWidget. It's pretty straightforward.
Just follow these 5 Simple steps
You can add SearchView
can be added as actionView
in menu using
app:useActionClass = "android.support.v7.widget.SearchView" .
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="rohksin.com.searchviewdemo.MainActivity">
<item
android:id="@+id/searchBar"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"
/>
</menu>
You should initialize SearchView in the onCreateOptionsMenu(Menu menu)
method.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem searchItem = menu.findItem(R.id.searchBar);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search People");
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
return true;
}
OnQueryTextListener
has two abstract methods
onQueryTextSubmit(String query)
onQueryTextChange(String newText
So your Activity skeleton would look like this
YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{
public boolean onQueryTextSubmit(String query)
public boolean onQueryTextChange(String newText)
}
You can provide the implementation for the abstract methods like this
public boolean onQueryTextSubmit(String query) {
// This method can be used when a query is submitted eg. creating search history using SQLite DB
Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.filter(newText);
return true;
}
Most important part. You can write your own logic to perform search.
Here is mine. This snippet shows the list of Name which contains the text typed in the SearchView
public void filter(String queryText)
{
list.clear();
if(queryText.isEmpty())
{
list.addAll(copyList);
}
else
{
for(String name: copyList)
{
if(name.toLowerCase().contains(queryText.toLowerCase()))
{
list.add(name);
}
}
}
notifyDataSetChanged();
}

date.ToString("o") // The Round-trip ("O", "o") Format Specifier
date.ToString("s") // The Sortable ("s") Format Specifier, conforming to ISO86801
Since you have applied different name for the components:
components: {
'i-tabs' : Tabs,
'i-tab-pane': Tabpane
}
You also need to have same name while you export: (Check to name in your Tabpane component)
name: 'Tabpane'
From the error, what I can say is you have not defined the name
in your component Tabpane
. Make sure to verify the name
and it should work fine with no error.
For all solutions instead of ".keyup" ".change" should be used or else the submit button wont be disabled when someone just selects data stored in cookies for any of the text fields.
I've always used Baretail for tailing in Windows. It's free and pretty nice.
Edit: for a better description of Baretail see this question
I believe you need quotes around the model
:
JSON.stringify({ "model": source })
If you want to get the value, you can use this code for a select element with the id="selectBox"
let myValue = document.querySelector("#selectBox").value;
If you want to get the text, you can use this code
var sel = document.getElementById("selectBox");
var text= sel.options[sel.selectedIndex].text;
I have tried below and it worked for me.
@S-Lott gives the right procedure, but expanding on the Unicode issues, the Python interpreter can provide more insights.
Jon Skeet is right (unusual) about the codecs
module - it contains byte strings:
>>> import codecs
>>> codecs.BOM
'\xff\xfe'
>>> codecs.BOM_UTF8
'\xef\xbb\xbf'
>>>
Picking another nit, the BOM
has a standard Unicode name, and it can be entered as:
>>> bom= u"\N{ZERO WIDTH NO-BREAK SPACE}"
>>> bom
u'\ufeff'
It is also accessible via unicodedata
:
>>> import unicodedata
>>> unicodedata.lookup('ZERO WIDTH NO-BREAK SPACE')
u'\ufeff'
>>>
You can also pass value directly via URL.
If you want to call method
public static void calling(string name){....}
then you should call usingHttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create("http://localhost:****/Report/calling?name=Priya);
webrequest.Method = "GET";
webrequest.ContentType = "application/text";
Just make sure you are using ?Object = value
in URL
See it might be worked -------
UPDATE table_name SET column_name=replace(column_name, ' ', '') //Remove white space
UPDATE table_name SET column_name=replace(column_name, '\n', '') //Remove newline
UPDATE table_name SET column_name=replace(column_name, '\t', '') //Remove all tab
Thanks Subroto
Cell A1 = find/the/position/of/the last slash
simple way to do it is reverse the text and then find the first slash as normal. Now you can get the length of the full text minus this number.
Like so:
=LEN(A1)-FIND("/",REVERSETEXT(A1),1)+1
This returns 21, the position of the last /
abc "$@"
$@
represents all the parameters given to your bash script.
Rails got ActiveSupport::CoreExtensions::String::Inflections
module that provides such methods. They're all worth looking at. For your example:
'Book Author Title'.parameterize.underscore.to_sym # :book_author_title
If getting this error trying to build .Net Core 2.0 app on VSTS then ensure your build definition is using the Hosted VS2017
Agent queue.
function isWholeNumber(num) {
return num === Math.round(num);
}
With sdk, you can't write to the root of internal storage. This cause your error.
Edit :
Based on your code, to use internal storage with sdk:
final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");
#include <stdio.h>
int main() {
printf("gcc version: %d.%d.%d\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
return 0;
}
This Error can also occur if you slice a negative point and pass it to the array. So check if you did
I went ahead and made a function for you:
Object.prototype.getValueByIndex = function (index) {
/*
Object.getOwnPropertyNames() takes in a parameter of the object,
and returns an array of all the properties.
In this case it would return: ["something","evenmore"].
So, this[Object.getOwnPropertyNames(this)[index]]; is really just the same thing as:
this[propertyName]
*/
return this[Object.getOwnPropertyNames(this)[index]];
};
let obj = {
'something' : 'awesome',
'evenmore' : 'crazy'
};
console.log(obj.getValueByIndex(0)); // Expected output: "awesome"

If you're working with SQL Developer, you have to put the dbms_view in lowercase. The rest compiled fine for me although I haven't called the procedure from code yet.

Try adding WorksheetFunction:

In the HTML source provided, the element #tfl
has an inline style "display:block
". Inline style will always override stylesheets styles…
Then, you have some options (while as you said you can't modify the html code nor using javascript):
display:none
with !important
rule (not recommended)put the div offscreen with theses rules :
#tfl {
position: absolute;
left: -9999px;
}
(DEMO)
Codes:
.backimage {width:99%; height:98%; position:absolute; background:transparent url("http://upload.wikimedia.org/wikipedia/commons/4/41/Brickwall_texture.jpg") repeat scroll 0% 0%; }
and
<div>
<div class="backimage"></div>
YOUR OTHER CONTENTTT
</div>
Just to add another option to the mix, there are several useful constants within the string
module. While more useful in other cases, they can be used here.
>>> from string import digits
>>> ''.join(c for c in "abc123def456" if c in digits)
'123456'
There are several constants in the module, including:
ascii_letters
(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)hexdigits
(0123456789abcdefABCDEF)If you are using these constants heavily, it can be worthwhile to covert them to a frozenset
. That enables O(1) lookups, rather than O(n), where n is the length of the constant for the original strings.
>>> digits = frozenset(digits)
>>> ''.join(c for c in "abc123def456" if c in digits)
'123456'
I would use javascript for this.
var txtFile = new XMLHttpRequest();
txtFile.open("GET", "http://my.remote.url/myremotefile.txt", true);
txtFile.onreadystatechange = function() {
if (txtFile.readyState === 4 && txtFile.status == 200) {
allText = txtFile.responseText;
}
document.getElementById('your div id').innerHTML = allText;
This is just a code sample, would need tweaking for all browsers, etc.
VMWare Player can be seen as a free, closed-source competitor to Virtualbox.
Initially VMWare Player (up to version 2.5) was intended to operate on fixed virtual operating systems (e.g. play back pre-created virtual disks).
Many advanced features such as vsphere are probably not required by most users, and VMWare Player will provide the same core technologies and 3D acceleration as the ESX Workstation solution.
From my experience VMWare Player 5 is faster than Virtualbox 4.2 RC3 and has better SMP performance. Both are great however, each with its own unique advantages. Both are somewhat lacking in 2D rendering performance.
See the official FAQ, and a feature comparison table.
One can also use blending:
im1 = Image.open("im1.png")
im2 = Image.open("im2.png")
blended = Image.blend(im1, im2, alpha=0.5)
blended.save("blended.png")
setState
return a Promise
In addition to passing a callback
to setState()
method, you can wrap it around an async
function and use the then()
method -- which in some cases might produce a cleaner code:
(async () => new Promise(resolve => this.setState({dummy: true}), resolve)()
.then(() => { console.log('state:', this.state) });
And here you can take this one more step ahead and make a reusable setState
function that in my opinion is better than the above version:
const promiseState = async state =>
new Promise(resolve => this.setState(state, resolve));
promiseState({...})
.then(() => promiseState({...})
.then(() => {
... // other code
return promiseState({...});
})
.then(() => {...});
This works fine in React 16.4, but I haven't tested it in earlier versions of React yet.
Also worth mentioning that keeping your callback code in componentDidUpdate
method is a better practice in most -- probably all, cases.
If you want the .wrapper
to be fullscreen, just add the following in the wrapper class:
position: absolute;
width: 100%;
height: 100%;
You can also add top: 0
and left:0
You could do it easily with an extension function rather than a regex ...
public static bool IsAlphaNum(this string str)
{
if (string.IsNullOrEmpty(str))
return false;
for (int i = 0; i < str.Length; i++)
{
if (!(char.IsLetter(str[i])) && (!(char.IsNumber(str[i]))))
return false;
}
return true;
}
Per comment :) ...
public static bool IsAlphaNum(this string str)
{
if (string.IsNullOrEmpty(str))
return false;
return (str.ToCharArray().All(c => Char.IsLetter(c) || Char.IsNumber(c)));
}
Here's the NoCache
attribute proposed by mattytommo, simplified by using the information from Chris Moschini's answer:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class NoCacheAttribute : OutputCacheAttribute
{
public NoCacheAttribute()
{
this.Duration = 0;
}
}
For static queries, like the one in your question, table names and column names need to be static.
For dynamic queries, you should generate the full SQL dynamically, and use sp_executesql to execute it.
Here is an example of a script used to compare data between the same tables of different databases:
Static query:
SELECT * FROM [DB_ONE].[dbo].[ACTY]
EXCEPT
SELECT * FROM [DB_TWO].[dbo].[ACTY]
Since I want to easily change the name of table
and schema
, I have created this dynamic query:
declare @schema varchar(50)
declare @table varchar(50)
declare @query nvarchar(500)
set @schema = 'dbo'
set @table = 'ACTY'
set @query = 'SELECT * FROM [DB_ONE].[' + @schema + '].[' + @table + '] EXCEPT SELECT * FROM [DB_TWO].[' + @schema + '].[' + @table + ']'
EXEC sp_executesql @query
Since dynamic queries have many details that need to be considered and they are hard to maintain, I recommend that you read: The curse and blessings of dynamic SQL
You must use a tool called a "header". In a header you declare the function that you want to use. Then you include it in both files. A header is a separate file included using the #include
directive. Then you may call the other function.
void MyFunc();
#include "other.h"
int main() {
MyFunc();
}
#include "other.h"
#include <iostream>
void MyFunc() {
std::cout << "Ohai from another .cpp file!";
std::cin.get();
}
ALTER TABLE table_name ALTER COLUMN id SET DEFAULT uuid_in((md5((random())::text))::cstring);
After reading @ZuzEL's answer, i used the above code as the default value of the column id and it's working fine.
For Python 3:
import urllib.request, urllib.error
url = 'http://www.google.com/asdfsf'
try:
conn = urllib.request.urlopen(url)
except urllib.error.HTTPError as e:
# Return code error (e.g. 404, 501, ...)
# ...
print('HTTPError: {}'.format(e.code))
except urllib.error.URLError as e:
# Not an HTTP-specific error (e.g. connection refused)
# ...
print('URLError: {}'.format(e.reason))
else:
# 200
# ...
print('good')
The native JavaScript implementation is Date.now()
.
Date.now()
and $.now()
return the same value:
Date.now(); // 1421715573651
$.now(); // 1421715573651
new Date(Date.now()) // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
new Date($.now()); // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
..and if you want the time formatted in hh-mm-ss:
var now = new Date(Date.now());

I'm assuming your first string is an actual Date object, please correct me if I'm wrong. If so, use the SimpleDateFormat object: http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html. The format string "h:mm" should take care of it.
Step 1: Add new column with integer or numeric as per your requirement
Step 2: Populate data from varchar column to numeric column
Step 3: drop varchar column
Step 4: change new numeric column name as per old varchar column
Could do this, but then the user has to separate the numbers by a space:
#include "stdio.h"
int main()
{
int minx, x, y, z;
printf("Enter four ints: ");
scanf( "%i %i %i %i", &minx, &x, &y, &z);
printf("You wrote: %i %i %i %i", minx, x, y, z);
}
With option context, this is possible without permanently setting use_inf_as_na
. For example:
with pd.option_context('mode.use_inf_as_na', True):
df = df.dropna(subset=['col1', 'col2'], how='all')
Of course it can be set to treat inf
as NaN
permanently with
pd.set_option('use_inf_as_na', True)
For older versions, replace use_inf_as_na
with use_inf_as_null
.
I'd approach this by default with passing a table valued function (that returns a table from a string) to the IN condition.
Here is the code for the UDF (I got it from Stack Overflow somewhere, i can't find the source right now)
CREATE FUNCTION [dbo].[Split] (@sep char(1), @s varchar(8000))
RETURNS table
AS
RETURN (
WITH Pieces(pn, start, stop) AS (
SELECT 1, 1, CHARINDEX(@sep, @s)
UNION ALL
SELECT pn + 1, stop + 1, CHARINDEX(@sep, @s, stop + 1)
FROM Pieces
WHERE stop > 0
)
SELECT
SUBSTRING(@s, start, CASE WHEN stop > 0 THEN stop-start ELSE 512 END) AS s
FROM Pieces
)
Once you got this your code would be as simple as this:
select * from Tags
where Name in (select s from dbo.split(';','ruby;rails;scruffy;rubyonrails'))
order by Count desc
Unless you have a ridiculously long string, this should work well with the table index.
If needed you can insert it into a temp table, index it, then run a join...
I know this topic is old, but I thought I could add something to it.
I could not make an Update with Select query work using SQL in MS Access 2010. I used Tomalak's suggestion to make this work. I had a screenshot, but am apparently too much of a newb on this site to be able to post it.
I was able to do this using the Query Design tool, but even as I was looking at a confirmed successful update query, Access was not able to show me the SQL that made it happen. So I could not make this work with SQL code alone.
I created and saved my select query as a separate query. In the Query Design tool, I added the table I'm trying to update the the select query I had saved (I put the unique key in the select query so it had a link between them). Just as Tomalak had suggested, I changed the Query Type to Update. I then just had to choose the fields (and designate the table) I was trying to update. In the "Update To" fields, I typed in the name of the fields from the select query I had brought in.
This format was successful and updated the original table.
The main difference between that and cron is that an exception will kill the daemon for good. You might want to wrap with an exception catcher and logger.
You have to convert the response to JSON using Gson.toJson(object)
.
For example:
return Response.status(Status.OK).entity(new Gson().toJson(Student)).build();
Anyone have any good experience with a "port" of a database from SQL Server to MySQL?
This should be fairly painful! I switched versions of MySQL from 4.x to 5.x and various statements wouldn't work anymore as they used to. The query analyzer was "improved" so statements which previously were tuned for performance would not work anymore as expected.
The lesson learned from working with a 500GB MySQL database: It's a subtle topic and anything else but trivial!
Probably the only choice is to read it on the client side and transfer it manually to the server (GET/POST/AJAX). Regards Artur

Sometimes administrators configure tomcat so that war files are deployed outside the tomcat folder. Even in that case:
After you have it deployed (check the /logs
dir for any problems), it should be accessible via: http://host:port/yourwebappname/
. So in your case, one of those:
http://bilgin.ath.cx/TestWebApp/
http://bilgin.ath.cx:8080/TestWebApp/
If you don't manage by doing the above and googling - turn to your support. There might be an alternative port, or there might be something wrong with the application (and therefore in the logs)
A compact way to go about doing that could be:
make foo && ./$_
Nice to have a one-liner so you can just re-run your executable again easily.
You can use the following script if you don't wish to use Wizard;
RESTORE DATABASE myDB
FROM DISK = N'C:\BackupDB.bak'
WITH REPLACE,RECOVERY,
MOVE N'HRNET' TO N'C:\MSSQL\Data\myDB.mdf',
MOVE N'HRNET_LOG' TO N'C:\MSSQL\Data\myDB.ldf'
I fixed it adding these lines in the build.grandle (App Module)

If you are using any spreadsheet application there is a basic function if()
with syntax:
if(<condition>, <yes>, <no>)
Syntax is exactly the same for ifelse()
in R:
ifelse(<condition>, <yes>, <no>)
The only difference to if()
in spreadsheet application is that R ifelse()
is vectorized (takes vectors as input and return vector on output). Consider the following comparison of formulas in spreadsheet application and in R for an example where we would like to compare if a > b and return 1 if yes and 0 if not.
In spreadsheet:
A B C
1 3 1 =if(A1 > B1, 1, 0)
2 2 2 =if(A2 > B2, 1, 0)
3 1 3 =if(A3 > B3, 1, 0)
In R:
> a <- 3:1; b <- 1:3
> ifelse(a > b, 1, 0)
[1] 1 0 0
ifelse()
can be nested in many ways:
ifelse(<condition>, <yes>, ifelse(<condition>, <yes>, <no>))
ifelse(<condition>, ifelse(<condition>, <yes>, <no>), <no>)
ifelse(<condition>,
ifelse(<condition>, <yes>, <no>),
ifelse(<condition>, <yes>, <no>)
)
ifelse(<condition>, <yes>,
ifelse(<condition>, <yes>,
ifelse(<condition>, <yes>, <no>)
)
)
To calculate column idnat2
you can:
df <- read.table(header=TRUE, text="
idnat idbp idnat2
french mainland mainland
french colony overseas
french overseas overseas
foreign foreign foreign"
)
with(df,
ifelse(idnat=="french",
ifelse(idbp %in% c("overseas","colony"),"overseas","mainland"),"foreign")
)
What is the condition has length > 1 and only the first element will be used
? Let's see:
> # What is first condition really testing?
> with(df, idnat=="french")
[1] TRUE TRUE TRUE FALSE
> # This is result of vectorized function - equality of all elements in idnat and
> # string "french" is tested.
> # Vector of logical values is returned (has the same length as idnat)
> df$idnat2 <- with(df,
+ if(idnat=="french"){
+ idnat2 <- "xxx"
+ }
+ )
Warning message:
In if (idnat == "french") { :
the condition has length > 1 and only the first element will be used
> # Note that the first element of comparison is TRUE and that's whay we get:
> df
idnat idbp idnat2
1 french mainland xxx
2 french colony xxx
3 french overseas xxx
4 foreign foreign xxx
> # There is really logic in it, you have to get used to it
Can I still use if()
? Yes, you can, but the syntax is not so cool :)
test <- function(x) {
if(x=="french") {
"french"
} else{
"not really french"
}
}
apply(array(df[["idnat"]]),MARGIN=1, FUN=test)
If you are familiar with SQL, you can also use CASE
statement in sqldf
package.
Below is my working code.
List<sampleObject> list = new ArrayList<>();
File file = new ClassPathResource("json/test.json").getFile();
ObjectMapper objectMapper = new ObjectMapper();
sampleObject = Arrays.asList(objectMapper.readValue(file, sampleObject[].class));
Hope it helps one!
Form elements can be accessed via the form's DOM element by name, not by "id" value. Give your form elements names if you want to access them like that, or else access them directly by "id" value:
document.getElementById("color").disabled = true;
edit — oh also, as pointed out by others, it's just "text", not "TextBox", for the "type" attribute.
You might want to invest a little time in reading some front-end development tutorials.
You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
JavaScript has Function-Level variable scope which means you will have to declare your variable outside $(document).ready()
function.
Or alternatively to make your variable to have global scope, simply dont use var
keyword before it like shown below. However generally this is considered bad practice because it pollutes the global scope but it is up to you to decide.
$(document).ready(function() {
intro = null; // it is in global scope now

Clickatell is a popular SMS gateway. It works in 200+ countries.
Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.
The HTTP/S method is as simple as this:
http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here
The SMTP method consists of sending a plain-text e-mail to: [email protected]
, with the following body:
user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567

The most simple way is to use pack() method before visualizing the JFrame object. here is an example:
myFrame frm = new myFrame();
frm.pack();
frm.setVisible(true);
Use Object.assign()
Example:
var a = {some: object};
var b = new Object;
Object.assign(b, a);
// b now equals a, but not by association.
A cleaner example that does the same thing:
var a = {some: object};
var b = Object.assign({}, a);
// Once again, b now equals a.

I have spent a couple of hours looking for the magic configuration to get Tomcat 7 running as a service on Windows Server 2008... no luck.
I do have a solution though.
My install of Tomcat 7 works just fine if I just jump into a console window and run...
C:\apache-tomcat-7.0.26\bin\start.bat
At this point another console window pops up and tails the logs (tail meaning show the server logs as they happen).
SOLUTION
Run the start.bat file as a Scheduled Task.
Start Menu > Accessories > System Tools > Task Scheduler
In the Actions Window: Create Basic Task...
Name the task something like "Start Tomcat 7" or something that makes sense a year from now.
Click Next >
Trigger should be set to "When the computer starts"
Click Next >
Action should be set to "Start a program"
Click Next >
Program/script: should be set to the location of the startup.bat file.
Click Next >
Click Finish
IF YOUR SERVER IS NOT BEING USED: Reboot your server to test this functionality
From the fine manual:
ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;
There's no need to specify the type when you're just changing the nullability.
You can do something like what i did with my List< Future< String > > or any other Arraylist, Type returned from other class called PingScan that returns List> because it implements service executor. Anyway the code down note that you can use foreach and retrieve data from the List.
PingScan p = new PingScan();
List<Future<String>> scanResult = p.checkThisIP(jFormattedTextField1.getText(), jFormattedTextField2.getText());
for (final Future<String> f : scanResult) {
try {
if (f.get() instanceof String) {
String ip = f.get();
Object[] data = {ip};
tableModel.addRow(data);
}
} catch (InterruptedException | ExecutionException ex) {
Logger.getLogger(gui.class.getName()).log(Level.SEVERE, null, ex);
}
}
You can do it this way:
var o = new { Id = 1, Name = "Foo" };
var o1 = new { Id = 2, Name = "Bar" };
var array = new[] { o, o1 };
var list = array.ToList();
list.Add(new { Id = 3, Name = "Yeah" });
It seems a little "hacky" to me, but it works - if you really need to have a list and can't just use the anonymous array.
I was getting this same error, but for me this was due to a method in a base class (in Project A) having the output type changed from a non-void type to void. A child class existed in Project B (which I didn't want used and had marked obsolete) that I missed when performing this update and hence started throwing this error.
1>CSC : error CS8104: An error occurred while writing the output file: System.NullReferenceException: Object reference not set to an instance of an object.
Original Code:
[Obsolete("Calling this method will throw an error")]
public override CompletionStatus Run()
{
throw new CustomException("Run process not supported.");
}
Revised Code:
[Obsolete("Calling this method will throw an error")]
public override void Run()
{
throw new CustomException("Run process not supported.");
}
I think the more tedious way is the only way to do it. I tried the first one and it doesn't compile (After commenting the '...')
No many shortcuts in 'C' I guess.ac
static void Main(string[] args)
{
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
}
static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
throw new NotImplementedException();
}
I also encountered this issue, for my case, it's because I upgrade my IntelliJ IDEA without upgrading the Lombok plugin. So they are incompatible.

Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?
Using reflection, this is the function i use :
public static bool doesPropertyExist(dynamic obj, string property)
{
return ((Type)obj.GetType()).GetProperties().Where(p => p.Name.Equals(property)).Any();
}
then..
if (doesPropertyExist(myDynamicObject, "myProperty")){
// ...
}
I put this question to the IETF HTTP WG. The comment from Roy Fielding (author of http/1.1 document in 1998) was that
"... an implementation would be broken to do anything other than to parse and discard that body if received"
RFC 7213 (HTTPbis) states:
"A payload within a GET request message has no defined semantics;"
It seems clear now that the intention was that semantic meaning on GET request bodies is prohibited, which means that the request body can't be used to affect the result.
There are proxies out there that will definitely break your request in various ways if you include a body on GET.
So in summary, don't do it.
We can prevent a thread from execution by using any of the 3 methods of Thread class:
yield()
method pauses the currently executing thread temporarily for giving a chance to the remaining waiting threads of the same priority or higher priority to execute. If there is no waiting thread or all the waiting threads have a lower priority then the same thread will continue its execution. The yielded thread when it will get the chance for execution is decided by the thread scheduler whose behavior is vendor dependent.
join()
If any executing thread t1 calls join()
on t2 (i.e. t2.join()
) immediately t1 will enter into waiting state until t2 completes its execution.
sleep()
Based on our requirement we can make a thread to be in sleeping state for a specified period of time (hope not much explanation required for our favorite method).
This is the best answer I have found so far to disable the keyboard (and I have seen a lot of them).
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // API 21
editText.setShowSoftInputOnFocus(false);
} else { // API 11-20
editText.setTextIsSelectable(true);
}
There is no need to use reflection or set the InputType
to null.
Here is how you re-enable the keyboard if needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // API 21
editText.setShowSoftInputOnFocus(true);
} else { // API 11-20
editText.setTextIsSelectable(false);
editText.setFocusable(true);
editText.setFocusableInTouchMode(true);
editText.setClickable(true);
editText.setLongClickable(true);
editText.setMovementMethod(ArrowKeyMovementMethod.getInstance());
editText.setText(editText.getText(), TextView.BufferType.SPANNABLE);
}
See this Q&A for why the complicated pre API 21 version is needed to undo setTextIsSelectable(true)
:
I have tested the setShowSoftInputOnFocus
on higher API devices, but after @androiddeveloper's comment below, I see that this needs to be more thoroughly tested.
Here is some cut-and-paste code to help test this answer. If you can confirm that it does or doesn't work for API 11 to 20, please leave a comment. I don't have any API 11-20 devices and my emulator is having problems.

If you don't mind importing the json
module, then the best way to handle it is through json.JSONDecodeError
(or json.decoder.JSONDecodeError
as they are the same) as using default errors like ValueError
could catch also other exceptions not necessarily connected to the json decode one.
from json.decoder import JSONDecodeError
try:
qByUser = byUsrUrlObj.read()
qUserData = json.loads(qByUser).decode('utf-8')
questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
# do whatever you want
//EDIT (Oct 2020):
As @Jacob Lee noted in the comment, there could be the basic common TypeError
raised when the JSON object is not a str
, bytes
, or bytearray
. Your question is about JSONDecodeError
, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:
from json.decoder import JSONDecodeError
try:
qByUser = byUsrUrlObj.read()
qUserData = json.loads(qByUser).decode('utf-8')
questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
# do whatever you want
except TypeError as e:
# do whatever you want in this case
I was stuck with the same problem. I found this page with all the possible versions of the KB2999226 also know as Update for Universal C Runtime in Windows.

Based on other answers, for linux
and mac
you can run the following:
echo "export PATH=\"`python3 -m site --user-base`/bin:$PATH\"" >> ~/.bashrc
source ~/.bashrc
instead of python3
you can use any other link to python version: python
, python2.7
, python3.6
, python3.9
, etc.
In order to know where the user packages are installed in the current OS (win, mac, linux), we run:
python3 -m site --user-base
We know that the scripts go to the bin/
folder where the packages are installed.
So we concatenate the paths:
echo `python3 -m site --user-base`/bin
Then we export that to an environment variable.
export PATH=\"`python3 -m site --user-base`/bin:$PATH\"
Finally, in order to avoid repeating the export command we add it to our .bashrc
file and we run source
to run the new changes, giving us the suggested solution mentioned at the beginning.
Option 1
In your index.js
file (i.e. webpack entry) add a require to your index.html
via file-loader plugin, e.g.:
require('file-loader?name=[name].[ext]!../index.html');
Once you build your project with webpack, index.html
will be in the output folder.
Option 2
Use html-webpack-plugin to avoid having an index.html at all. Simply have webpack generate the file for you.
In this case if you want to keep your own index.html
file as template, you may use this configuration:
{
plugins: [
new HtmlWebpackPlugin({
template: 'src/index.html'
})
]
}
See the docs for more information.
This can mean a lot of things, but the most common one is that the class contained in the file doesn't have the same name as the file itself. So, check if your class is also called HelloWorld2.
The typical use is
void* ret = NULL;
pthread_t tid = something; /// change it suitably
if (pthread_join (tid, &ret))
handle_error();
// do something with the return value ret
Use where
with a !=
operator in combination with whereNull
Code::where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id')->get()
Colon is always "true":
while :; do foo; sleep 2; done
just for getting the links, without B.soup and regex:
import urllib2
url="http://www.somewhere.com"
page=urllib2.urlopen(url)
data=page.read().split("</a>")
tag="<a href=\""
endtag="\">"
for item in data:
if "<a href" in item:
try:
ind = item.index(tag)
item=item[ind+len(tag):]
end=item.index(endtag)
except: pass
else:
print item[:end]
for more complex operations, of course BSoup is still preferred.

In the Solution Explorer window, right click the project you want to use your class library from and click the 'Add Reference' menu item. Then if the class library is in the same solution file, go to the projects tab and select it; if it's not in the same tab, you can go to the Browse tab and find it that way.
Then you can use anything in that assembly.
The number
filter formats the number with thousands separators, so it's not strictly a math function.
Moreover, its decimal 'limiter' doesn't ceil
any chopped decimals (as some other answers would lead you to believe), but rather round
ing them.
So for any math function you want, you can inject it (easier to mock than injecting the whole Math object) like so:
myModule.filter('ceil', function () {
return Math.ceil;
});
No need to wrap it in another function either.
You need to transform the object you are getting back into an array in the format that jQueryUI expects.
You can use $.map
to transform the dealers
object into that array.
$('#dealerName').autocomplete({
source: function (request, response) {
$.getJSON("/example/location/example.json?term=" + request.term, function (data) {
response($.map(data.dealers, function (value, key) {
return {
label: value,
value: key
};
}));
});
},
minLength: 2,
delay: 100
});
Note that when you select an item, the "key" will be placed in the text box. You can change this by tweaking the label
and value
properties that $.map
's callback function return.
Alternatively, if you have access to the server-side code that is generating the JSON, you could change the way the data is returned. As long as the data:
label
property, a value
property, or both, orIn other words, if you can format the data like this:
[{ value: "1463", label: "dealer 5"}, { value: "269", label: "dealer 6" }]
or this:
["dealer 5", "dealer 6"]
Then your JavaScript becomes much simpler:
$('#dealerName').autocomplete({
source: "/example/location/example.json"
});
You don't need to set name , just giving an id is enough.
<input type="hidden" id="testId" />
and than with jquery you can use 'val()' method like below:
$('#testId').val("work");
If you don't call the favicon, favicon.ico
, you can use that tag to specify the actual path (incase you have it in an images/
directory). The browser/webpage looks for favicon.ico
in the root directory by default.
main() {
double a;
a=3669.0;
int b;
b=a;
printf("b is %d",b);
}
output is :b is 3669
when you write b=a; then its automatically converted in int

This is called Implicit Type Conversion Read more here https://www.geeksforgeeks.org/implicit-type-conversion-in-c-with-examples/
Use given lines in OnActionExecuting for Action and Controller name.
string actionName = this.ControllerContext.RouteData.Values["action"].ToString();
string controllerName = this.ControllerContext.RouteData.Values["controller"].ToString();
first fetch all the tags in that specific remote
git fetch <remote> 'refs/tags/*:refs/tags/*'
or just simply type
git fetch <remote>
Then check for the available tags
git tag -l
then switch to that specific tag using below command
git checkout tags/<tag_name>
Hope this will helps you!
This is a way:
Using apktool
to decode:
$ apktool d -f {apkfile} -o {output folder}
Next, using JADX (at github.com/skylot/jadx)
$ jadx -d {output folder} {apkfile}
2 tools extract and decompiler to same output folder.
You need a single stream, opened for both reading and writing.
FileStream fileStream = new FileStream(
@"c:\words.txt", FileMode.OpenOrCreate,
FileAccess.ReadWrite, FileShare.None);
It's simple use:
long millis = new Date().getTime();
if you want it in particular format then you need Formatter like below
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String millisInString = dateFormat.format(new Date());
