Here is what I use when I don't have access to the source string, e.g. for downloaded HTML:
// replace newlines with <br>
public static String replaceNewlinesWithBreaks(String source) {
return source != null ? source.replaceAll("(?:\n|\r\n)","<br>") : "";
}
For XML you should probably edit that to replace with <br/>
instead.
Example of its use in a function (additional calls removed for clarity):
// remove HTML tags but preserve supported HTML text styling (if there is any)
public static CharSequence getStyledTextFromHtml(String source) {
return android.text.Html.fromHtml(replaceNewlinesWithBreaks(source));
}
...and a further example:
textView.setText(getStyledTextFromHtml(someString));
Nothing worked for me for these errors EXCEPT
... was not expected,
... there is an error in XML document (1,2)
... System.FormatException Input String was not in correct format ...
Except this way
1- You need to inspect the xml response as string (the response that you are trying to de-serialize to an object)
2- Use online tools for string unescape and xml prettify/formatter
3- MAKE SURE that the C# Class (main class) you are trying to map/deserialize the xml string to HAS AN XmlRootAttribute that matches the root element of the response.
Exmaple:
My XML Response was staring like :
<ShipmentCreationResponse xmlns="http://ws.aramex.net/ShippingAPI/v1/">
<Transaction i:nil="true" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"/>
....
And the C# class definition + attributes was like :
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ServiceModel.MessageContractAttribute(WrapperName="ShipmentCreationResponse", WrapperNamespace="http://ws.aramex.net/ShippingAPI/v1/", IsWrapped=true)]
public partial class ShipmentCreationResponse {
.........
}
Note that the class definition does not have "XmlRootAttribute"
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://ws.aramex.net/ShippingAPI/v1/", IsNullable = false)]
And when i try to de serialize using a generic method :
public static T Deserialize<T>(string input) where T : class
{
System.Xml.Serialization.XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(typeof(T));
using (System.IO.StringReader sr = new System.IO.StringReader(input))
{
return (T)ser.Deserialize(sr);
}
}
var _Response = GeneralHelper.XMLSerializer.Deserialize<ASRv2.ShipmentCreationResponse>(xml);
I was getting the errors above
... was not expected, ... there is an error in XML document (1,2) ...
Now by just adding the "XmlRootAttribute" that fixed the issue for ever and for every other requests/responses i had a similar issue with:
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://ws.aramex.net/ShippingAPI/v1/", IsNullable = false)]
..
[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://ws.aramex.net/ShippingAPI/v1/")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://ws.aramex.net/ShippingAPI/v1/", IsNullable = false)]
public partial class ShipmentCreationResponse
{

}
In VB.NET:
Dim webClient As New System.Net.WebClient
Dim result As String = webClient.DownloadString("http://api.hostip.info/?ip=68.180.206.184")
In C#:
System.Net.WebClient webClient = new System.Net.WebClient();
string result = webClient.DownloadString("http://api.hostip.info/?ip=68.180.206.184");
I resolved my problem, if i configure like follow:
location = /login {
index login2.html;
}
It'll show the 403 error.
[error] 4212#2916: *2 directory index of "D:\path/to/login/" is forbidden
I've tried autoindex on
, but not working.
If i change my configure like this, it works.
location = /login/ {
index login2.html;
}
I think the exact matching, if it's a path should be a directory.
if you want to change the base of logarithm, just add:
plt.yscale('log',base=2)
Before Matplotlib 3.3, you would have to use basex/basey as the bases of log

As the other poster mention, py2exe
, will generate an executable + some libraries to load. You can also have some data to add to your program.
Next step is to use an installer, to package all this into one easy-to-use installable/unistallable program.
I have used InnoSetup with delight for several years and for commercial programs, so I heartily recommend it.
A web service differs from a web site in that a web service provides information consumable by software rather than humans. As a result, we are usually talking about exposed JSON, XML, or SOAP services.
Web services are a key component in "mashups". Mashups are when information from many websites is automatically aggregated into a new and useful service. For example, there are sites that aggregate Google Maps with information about police reports to give you a graphical representation of crime in your area. Another type of mashup would be to take real stock data provided by another site and combine it with a fake trading application to create a stock-market "game".
Web services are also used to provide news (see RSS), latest items added to a site, information on new products, podcasts, and other great features that make the modern web turn.
Hope this helps!
If I've understood your problem correctly, there are two possible problems here:
resultset
is null
- I assume that this can't be the case as if it was you'd get an exception in your while loop and nothing would be output.resultset.getString(i++)
will get columns 1,2,3 and so on from each subsequent row.I think that the second point is probably your problem here.
Lets say you only had 1 row returned, as follows:
Col 1, Col 2, Col 3
A , B, C
Your code as it stands would only get A - it wouldn't get the rest of the columns.
I suggest you change your code as follows:
ResultSet resultset = ...;
ArrayList<String> arrayList = new ArrayList<String>();
while (resultset.next()) {
int i = 1;
while(i <= numberOfColumns) {
arrayList.add(resultset.getString(i++));
}
System.out.println(resultset.getString("Col 1"));
System.out.println(resultset.getString("Col 2"));
System.out.println(resultset.getString("Col 3"));
System.out.println(resultset.getString("Col n"));
}
Edit:
To get the number of columns:
ResultSetMetaData metadata = resultset.getMetaData();
int numberOfColumns = metadata.getColumnCount();
Given that you're only converting to int
s to then perform a comparison, I'd just switch the table definition around to using varchar
also:
Create table #myTempTable
(
num varchar(12)
)
insert into #myTempTable (num) values (1),(2),(3),(4),(5)
and remove all of the attempted CONVERT
s from the rest of the query.
SELECT a.name, a.value AS value, COUNT(*) AS pocet
FROM
(SELECT item.name, value.value
FROM mdl_feedback AS feedback
INNER JOIN mdl_feedback_item AS item
ON feedback.id = item.feedback
INNER JOIN mdl_feedback_value AS value
ON item.id = value.item
WHERE item.typ = 'multichoicerated' AND item.feedback IN (43)
) AS a
INNER JOIN #myTempTable
on a.value = #myTempTable.num
GROUP BY a.name, a.value ORDER BY a.name
this works for me, sudo apt-get install libx11-dev
I've found pickling confusing (possibly because I'm thick). I found that this works, though:
myDictionaryString=str(myDictionary)
Which you can then write to a text file. I gave up trying to use pickle as I was getting errors telling me to write integers to a .dat file. I apologise for not using pickle.
Dear olga is clear what the message says. Turn off the custom errors to see the details about this error for fix it, and then you close them back. So add mode="off" as:
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Relative answer: Deploying website: 500 - Internal server error
By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.
Shutdown Hooks are unstarted threads that are registered with Runtime.addShutdownHook().JVM does not give any guarantee on the order in which shutdown hooks are started.For more info refer http://techno-terminal.blogspot.in/2015/08/shutdown-hooks.html

Note : This does not consider all the containers such as, unordered_map etc. but is still great to look at. It is just a cleaner version of this
Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.
In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.
Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.
Thanks to this question (and answers), I discovered an easy way to get at the exact NumberFormat string for virtually any format that Excel has to offer.
Step 1: In the user interface, set a cell to the NumberFormat you want to use.
In my example, I selected the Chinese (PRC) Currency from the options contained in the "Account Numbers Format" combo box.
Step 2: Expand the Number Format dropdown and select "More Number Formats...".
Step 3: In the Number tab, in Category, click "Custom".
The "Sample" section shows the Chinese (PRC) currency formatting that I applied.
The "Type" input box contains the NumberFormat string that you can use programmatically.
So, in this example, the NumberFormat of my Chinese (PRC) Currency cell is as follows:
_ [$¥-804]* #,##0.00_ ;_ [$¥-804]* -#,##0.00_ ;_ [$¥-804]* "-"??_ ;_ @_
If you do these steps for each NumberFormat that you desire, then the world is yours.
I hope this helps.
A possible way is to use the modulo operator to only let the values stay in the int32 range, and then cast it to int.
var intValue= (int)(longValue % Int32.MaxValue);
I created a custom query scope in BaseModel (my all models extends this class):
/**
* Add a relationship exists condition (BelongsTo).
*
* @param Builder $query
* @param string|Model $relation Relation string name or you can try pass directly model and method will try guess relationship
* @param mixed $modelOrKey
* @return Builder|static
*/
public function scopeWhereHasRelated(Builder $query, $relation, $modelOrKey = null)
{
if ($relation instanceof Model && $modelOrKey === null) {
$modelOrKey = $relation;
$relation = Str::camel(class_basename($relation));
}
return $query->whereHas($relation, static function (Builder $query) use ($modelOrKey) {
return $query->whereKey($modelOrKey instanceof Model ? $modelOrKey->getKey() : $modelOrKey);
});
}
You can use it in many contexts for example:
Event::whereHasRelated('participants', 1)->isNotEmpty(); // where has participant with id = 1
Furthermore, you can try to omit relationship name and pass just model:
$participant = Participant::find(1);
Event::whereHasRelated($participant)->first(); // guess relationship based on class name and get id from model instance
This should do the trick:
<% if (typeof(date) !== "undefined") { %>
<span class="date"><%= date %></span>
<% } %>
Remember that in underscore.js templates if
and for
are just standard javascript syntax wrapped in <% %>
tags.
This only works in Oracle 10G and greater.
Basically, you use regex_substr to do a split on the string.
header('Location: '.$_SERVER['REQUEST_URI']);
I do not understand why the answers are so complex here.
Here is a closure:
var a = 42;
function b() { return a; }
Yes. You probably use that many times a day.
There is no reason to believe closures are a complex design hack to address specific problems. No, closures are just about using a variable that comes from a higher scope from the perspective of where the function was declared (not run).
Now what it allows you to do can be more spectacular, see other answers.
I would not advise adding ValueTuple
as a package reference to the .net Framework projects. As you know this assembly is available from 4.7 .NET Framework.
There can be certain situations when your project will try to include at all costs ValueTuple
from .NET Framework folder instead of package folder and it can cause some assembly not found errors.
We had this problem today in company. We had solution with 2 projects (I oversimplify that) :
Lib
Web
Lib
was including ValueTuple and Web
was using Lib
. It turned out that by some unknown reason Web
when trying to resolve path to ValueTuple
was having HintPath
into .NET Framework directory and was taking incorrect version. Our application was crashing because of that. ValueTuple
was not defined in .csproj
of Web
nor HintPath
for that assembly. The problem was very weird. Normally it would copy the assembly from package folder. This time was not normal.
For me it is always risk to add System.*
package references. They are often like time-bomb. They are fine at start and they can explode in your face in the worst moment. My rule of thumb: Do not use System.*
Nuget package for .NET Framework if there is no real need for them.
We resolved our problem by adding manually ValueTuple
into .csproj
file inside Web
project.
PHP and MySQL have their own default timezone configurations. You should synchronize time between your data base and web application, otherwise you could run some issues.

To answer your extra question
:
You can set which rows should be repeated on every page using:
$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);
Now, row 1, 2, 3, 4 and 5 will be repeated.
val source_html = Source.fromResource("file.html").mkString
You literally just pass them in std::thread(func1,a,b,c,d);
that should have compiled if the objects existed, but it is wrong for another reason. Since there is no object created you cannot join or detach the thread and the program will not work correctly. Since it is a temporary the destructor is immediately called, since the thread is not joined or detached yet std::terminate
is called. You could std::join
or std::detach
it before the temp is destroyed, like std::thread(func1,a,b,c,d).join();//or detach
.
This is how it should be done.
std::thread t(func1,a,b,c,d);
t.join();
You could also detach the thread, read-up on threads if you don't know the difference between joining and detaching.
Bulk folder creation and grant permission works me by using the below powershell script.
Import-Csv "D:\Scripts\foldernames.csv" | foreach-object {
$username = $_.foldername
# foldername is the header of csv file
$domain = “example.com”
$folder= "D:\Users"
$domainusername = $domain+“\”+$username
New-Item $folder\$username –Type Directory
Get-Acl $folder\$username
$acl = Get-Acl $folder\$username
$acl.SetAccessRuleProtection($True, $False)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Administrators","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("SYSTEM","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("$domain\Domain Admins","Read", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule($domainusername,"Modify", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
Set-Acl $folder\$username $acl
}
Note: You have to create same domain username in csv file otherwise you will get permission issues
tput cols
tells you the number of columns.tput lines
tells you the number of rows.A simple way is to use python. in python terminal type
r"C:\Users\surfcat\Desktop\2006_dissimilarity.csv" and you'll get back 'C:\Users\surfcat\Desktop\2006_dissimilarity.csv'
For me this worked:
<TextBlock Text="{Binding Date , StringFormat=g}" Width="130"/>
If want to show seconds also using G instead of g :
<TextBlock Text="{Binding Date , StringFormat=G}" Width="130"/>
Also if want for changing date type to another like Persian , using Language :
<TextBlock Text="{Binding Date , StringFormat=G}" Width="130" Language="fa-IR"/>
You won't be able to load an image outside of the project directory or from a user level directory, hence the "cannot access local resource warning".
But if you were to place the file in a root folder of your project like in {rootFolder}\Content\my-image.jpg
and referenced it like so:
<img src="/Content/my-image.jpg" />
Your problem is in this line: Message messageObject = new Message ();

StringComparison.InvariantCultureIgnoreCase just do the job for me:
.Where(fi => fi.DESCRIPTION.Contains(description, StringComparison.InvariantCultureIgnoreCase));
Date#parse
is deprecated . The alternative is :
java.text.DateFormat#parse
thereFore :
new SimpleDateFormat("E MMM dd H:m:s z yyyy", Locale.ARABIC).parse(testDate)
You could try a for loop
for func,args,kwargs in zip([a,b,c,d],
[args_a,args_b,args_c,args_d],
[kw_a,kw_b,kw_c,kw_d]):
try:
func(*args, **kwargs)
break
except:
pass
This way you can loop as many functions as you want without making the code look ugly
Following @patrick-desjardins answer, I implemented abstract and it's implementation class along with @Test
as follows:
Abstract class - ABC.java
import java.util.ArrayList;
import java.util.List;
public abstract class ABC {
abstract String sayHello();
public List<String> getList() {
final List<String> defaultList = new ArrayList<>();
defaultList.add("abstract class");
return defaultList;
}
}
As Abstract classes cannot be instantiated, but they can be subclassed, concrete class DEF.java, is as follows:
public class DEF extends ABC {
@Override
public String sayHello() {
return "Hello!";
}
}
@Test class to test both abstract as well as non-abstract method:
import org.junit.Before;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.empty;
import static org.hamcrest.Matchers.is;
import static org.hamcrest.Matchers.not;
import static org.hamcrest.Matchers.contains;
import java.util.Collection;
import java.util.List;
import static org.hamcrest.Matchers.equalTo;
import org.junit.Test;
public class DEFTest {
private DEF def;
@Before
public void setup() {
def = new DEF();
}
@Test
public void add(){
String result = def.sayHello();
assertThat(result, is(equalTo("Hello!")));
}
@Test
public void getList(){
List<String> result = def.getList();
assertThat((Collection<String>) result, is(not(empty())));
assertThat(result, contains("abstract class"));
}
}
It's the ternary form of the if-else operator. The above statement basically reads like this:
if ($add_review) then {
return FALSE; //$add_review evaluated as True
} else {
return $arg //$add_review evaluated as False
}

You can use Axios (a promise-based HTTP client for Node.js) to download images in the order of your choosing in an asynchronous environment:
npm i axios
Then, you can use the following basic example to begin downloading images:
const fs = require('fs');
const axios = require('axios');
/* ============================================================
Function: Download Image
============================================================ */
const download_image = (url, image_path) =>
axios({
url,
responseType: 'stream',
}).then(
response =>
new Promise((resolve, reject) => {
response.data
.pipe(fs.createWriteStream(image_path))
.on('finish', () => resolve())
.on('error', e => reject(e));
}),
);
/* ============================================================
Download Images in Order
============================================================ */
(async () => {
let example_image_1 = await download_image('https://example.com/test-1.png', 'example-1.png');
console.log(example_image_1.status); // true
console.log(example_image_1.error); // ''
let example_image_2 = await download_image('https://example.com/does-not-exist.png', 'example-2.png');
console.log(example_image_2.status); // false
console.log(example_image_2.error); // 'Error: Request failed with status code 404'
let example_image_3 = await download_image('https://example.com/test-3.png', 'example-3.png');
console.log(example_image_3.status); // true
console.log(example_image_3.error); // ''
})();
plt.rcParams['figure.figsize'] = (15, 5)
IF you are checking one variable against multiple condition then you would use something like this Here the block of code where the condition is true will be executed and other blocks will be ignored.
IF(@Var1 Condition1)
BEGIN
/*Your Code Goes here*/
END
ELSE IF(@Var1 Condition2)
BEGIN
/*Your Code Goes here*/
END
ELSE --<--- Default Task if none of the above is true
BEGIN
/*Your Code Goes here*/
END
If you are checking conditions against multiple variables then you would have to go for multiple IF Statements, Each block of code will be executed independently from other blocks.
IF(@Var1 Condition1)
BEGIN
/*Your Code Goes here*/
END
IF(@Var2 Condition1)
BEGIN
/*Your Code Goes here*/
END
IF(@Var3 Condition1)
BEGIN
/*Your Code Goes here*/
END
After every IF statement if there are more than one statement being executed you MUST put them in BEGIN..END Block. Anyway it is always best practice to use BEGIN..END blocks
Update
Found something in your code some BEGIN END you are missing
ELSE IF(@ID IS NOT NULL AND @ID in (SELECT ID FROM Places)) -- Outer Most Block ELSE IF
BEGIN
SELECT @MyName = Name ...
...Some stuff....
IF(SOMETHNG_1) -- IF
--BEGIN
BEGIN TRY
UPDATE ....
END TRY
BEGIN CATCH
SELECT ERROR_MESSAGE() AS 'Message'
RETURN -1
END CATCH
-- END
ELSE IF(SOMETHNG_2) -- ELSE IF
-- BEGIN
BEGIN TRY
UPDATE ...
END TRY
BEGIN CATCH
SELECT ERROR_MESSAGE() AS 'Message'
RETURN -1
END CATCH
-- END
ELSE -- ELSE
BEGIN
BEGIN TRY
UPDATE ...
END TRY
BEGIN CATCH
SELECT ERROR_MESSAGE() AS 'Message'
RETURN -1
END CATCH
END
--The above works I then insert this below and these if statement become nested----
IF(@A!= @SA)
BEGIN
exec Store procedure
@FIELD = 15,
... more params...
END
IF(@S!= @SS)
BEGIN
exec Store procedure
@FIELD = 10,

Using relative instead of absolute file path solved the problem for me.
I had the same issue and setting allow_url_fopen=on
did not help. This means for instance :
use
$file="folder/file.ext";
instead of
$file="https://website.com/folder/file.ext";
in
$f=fopen($file,"r+");
In SQL Server 2016 SSMS expand 'DATABASNAME' > expand 'SECURITY' > expand 'SCHEMA' ; right click 'SCHEMAS' from the popup left click 'NEW SCHEMAS...' add the name on the window that opens and add an owner i.e dbo click 'OK' button
I also get this issue when i change package name of my application.
In your android studio project find "google-services.json" file. Open it. and check whether package name of your application is same as written in this file.
The package name of your application and package name written in "google-services.json" file must be same.
You can achieve it by code also, In you Global.asax file in Session_Start event write response.redirect to your start page like following.
void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
Response.Redirect("~/Index.aspx");
}
You can get redirect page name from database or any other storage to change the application start page while application is running no need to edit web.config or change any IIS settings
<execute-test-successful-condition> if <test> else <execute-test-fail-condition>
with your code-snippet it would become,
count = 0 if count == N else N + 1
Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override
, but in Java 1.5 can only be applied to methods overriding a superclass method).
Go to your project/IDE preferences and set the Java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from Eclipse.

db = ActiveRecord::Base.connection.raw_connection
db.create_function('regexp', 2) do |func, pattern, expression|
func.result = expression.to_s.match(Regexp.new(pattern.to_s, Regexp::IGNORECASE)) ? 1 : 0
end
That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.
Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges.
Since back edges are those edges (u
, v
) connecting a vertex u
to an ancestor
v
in a depth-first tree, so no back edges means there are only tree edges, so
there is no cycle.
So we can simply run DFS. If find a back edge, there is a cycle. The complexity
is O(V)
instead of O(E + V)
. Since if there is a back edge, it must
be found before seeing |V|
distinct edges. This is because in a acyclic (undirected) forest, |E| = |V| + 1
.
Putting together several answers from above, this is what I ended up using:
var validationErrors = ModelState.Values.Where(E => E.Errors.Count > 0)
.SelectMany(E => E.Errors)
.Select(E => E.ErrorMessage)
.ToList();
validationErrors
ends up being a List<string>
that contains each error message. From there, it's easy to do what you want with that list.
Make sure that the field has this attribute in its html.

and then use this in your script:
$("#NameOfYourTextBox").change(function () {_x000D_
$(this).val($(this).val().toUpperCase());_x000D_
});

You have used '/0'
instead of '\0'
. This is incorrect: the '\0'
is a null character, while '/0'
is a multicharacter literal.
Moreover, in C it is OK to skip a zero in your condition:
while (*(forward++)) {
...
}
is a valid way to check character, integer, pointer, etc. for being zero.
If you are familiar with LaTex you might want to consider pylatex
One of the advantages of pylatex is that it is easy to control the image quality. The images in your pdf will be of the same quality as the original images. When using reportlab, I experienced that the images were automatically compressed, and the image quality reduced.
The disadvantage of pylatex is that, since it is based on LaTex, it can be hard to place images exactly where you want on the page. However, I have found that using the position argument in the Figure class, and sometimes Subfigure, gives good enough results.
Example code for creating a pdf with a single image:
from pylatex import Document, Figure
doc = Document(documentclass="article")
with doc.create(Figure(position='p')) as fig:
fig.add_image('Lenna.png')
doc.generate_pdf('test', compiler='latexmk', compiler_args=["-pdf", "-pdflatex=pdflatex"], clean_tex=True)
In addition to installing pylatex (pip install pylatex), you need to install LaTex. For Ubuntu and other Debian systems you can run sudo apt-get install texlive-full
. If you are using Windows I would recommend MixTex

Try removing "package-lock.json" and running "npm install && npm update", it'll install the latest version and clear all errors.
You code is correct. replace items with .items as below

You can use method getDate():
$('#calendar').datepicker({
dateFormat: 'yy-m-d',
inline: true,
onSelect: function(dateText, inst) {
var date = $(this).datepicker('getDate'),
day = date.getDate(),
month = date.getMonth() + 1,
year = date.getFullYear();
alert(day + '-' + month + '-' + year);
}
});
They are not really same mutexes, lock_guard<muType>
has nearly the same as std::mutex
, with a difference that it's lifetime ends at the end of the scope (D-tor called) so a clear definition about these two mutexes :
lock_guard<muType>
has a mechanism for owning a mutex for the duration of a scoped block.
And
unique_lock<muType>
is a wrapper allowing deferred locking, time-constrained attempts at locking, recursive locking, transfer of lock ownership, and use with condition variables.
Here is an example implemetation :
#include <iostream>
#include <thread>
#include <mutex>
#include <condition_variable>
#include <functional>
#include <chrono>
using namespace std::chrono;
class Product{
public:
Product(int data):mdata(data){
}
virtual~Product(){
}
bool isReady(){
return flag;
}
void showData(){
std::cout<<mdata<<std::endl;
}
void read(){
std::this_thread::sleep_for(milliseconds(2000));
std::lock_guard<std::mutex> guard(mmutex);
flag = true;
std::cout<<"Data is ready"<<std::endl;
cvar.notify_one();
}
void task(){
std::unique_lock<std::mutex> lock(mmutex);
cvar.wait(lock, [&, this]() mutable throw() -> bool{ return this->isReady(); });
mdata+=1;
}
protected:
std::condition_variable cvar;
std::mutex mmutex;
int mdata;
bool flag = false;
};
int main(){
int a = 0;
Product product(a);
std::thread reading(product.read, &product);
std::thread setting(product.task, &product);
reading.join();
setting.join();
product.showData();
return 0;
}
In this example, i used the unique_lock<muType>
with condition variable
To create an empty multidimensional array in NumPy (e.g. a 2D array m*n
to store your matrix), in case you don't know m
how many rows you will append and don't care about the computational cost Stephen Simmons mentioned (namely re-buildinging the array at each append), you can squeeze to 0 the dimension to which you want to append to: X = np.empty(shape=[0, n])
.
This way you can use for example (here m = 5
which we assume we didn't know when creating the empty matrix, and n = 2
):
import numpy as np
n = 2
X = np.empty(shape=[0, n])
for i in range(5):
for j in range(2):
X = np.append(X, [[i, j]], axis=0)
print X
which will give you:
[[ 0. 0.]
[ 0. 1.]
[ 1. 0.]
[ 1. 1.]
[ 2. 0.]
[ 2. 1.]
[ 3. 0.]
[ 3. 1.]
[ 4. 0.]
[ 4. 1.]]
Those arrows are part of the Shadow DOM, which are basically DOM elements on your page which are hidden from you. If you're new to the idea, a good introductory read can be found here.
For the most part, the Shadow DOM saves us time and is good. But there are instances, like this question, where you want to modify it.
You can modify these in Webkit now with the right selectors, but this is still in the early stages of development. The Shadow DOM itself has no unified selectors yet, so the webkit selectors are proprietary (and it isn't just a matter of appending -webkit
, like in other cases).
Because of this, it seems likely that Opera just hasn't gotten around to adding this yet. Finding resources about Opera Shadow DOM modifications is tough, though. A few unreliable internet sources I've found all say or suggest that Opera doesn't currently support Shadow DOM manipulation.
I spent a bit of time looking through the Opera website to see if there'd be any mention of it, along with trying to find them in Dragonfly...neither search had any luck. Because of the silence on this issue, and the developing nature of the Shadow DOM + Shadow DOM manipulation, it seems to be a safe conclusion that you just can't do it in Opera, at least for now.
I just changed availability date to a future date. After doing that, I received following message -
You have selected an Available Date in the future. This will remove your currently live version from the App Store until the new date. Changing Available Date affects all versions of the application, both Ready For Sale and In Review.
Which means that the app is removed and no longer available.
Also you can try this:
[style.background-image]="'url(' + photo + ')'"
You could also just do it in one go, by doing the sort first and using head to take the first 3 of each group.
In[34]: df.sort_values(['job','count'],ascending=False).groupby('job').head(3)
Out[35]:
count job source

It is a little bit similar to the other suggestions but still easy and quite good to remember.
XmlDocument d = new XmlDocument();
d.Load(@"D:\Work_Time_Calculator\10-07-2013.xml");
XmlNodeList n = d.GetElementsByTagName("Short_Fall");
if(n != null) {
Console.WriteLine(n[0].InnerText); //Will output '08:29:57'
}
or you could wrap in foreach loop to print each value
XmlDocument d = new XmlDocument();
d.Load(@"D:\Work_Time_Calculator\10-07-2013.xml");
XmlNodeList n = d.GetElementsByTagName("Short_Fall");
if(n != null) {
foreach(XmlNode curr in n) {
Console.WriteLine(curr.InnerText);

In your test, you are comparing the two TestParent
beans, not the single TestedChild
bean.
Also, Spring proxies your @Configuration
class so that when you call one of the @Bean
annotated methods, it caches the result and always returns the same object on future calls.
See here:
the document class selector:
document.getElementsByClassName('drill_cursor')[0].addEventListener('click',function(){},false)
also the document query selector https://developer.mozilla.org/en-US/docs/Web/API/document.querySelector
document.querySelector(".drill_cursor").addEventListener('click',function(){},false)
If you're going to use a Control
from another thread before showing or doing other things with the Control
, consider forcing the creation of its handle within the constructor. This is done using the CreateHandle
function.
In a multi-threaded project, where the "controller" logic isn't in a WinForm, this function is instrumental in Control
constructors for avoiding this error.
If you use a website and you fill out a form to submit information (your social security number for example) you want to be sure that the information is being sent to the site you think it's being sent to. So browsers were built to say, by default, 'Do not send information to a domain other than the domain being visited).
Eventually that became too limiting but the default idea still remains in browsers. Don't let the web page send information to a different domain. But this is all browser checking. Chrome and firefox, etc have built in code that says 'before send this request, we're going to check that the destination matches the page being visited'.
Postman (or CURL on the cmd line) doesn't have those built in checks. You're manually interacting with a site so you have full control over what you're sending.
Another way is to let Eclipse do the import work for you. Hover your mouse over the com.google.android.gms
import that can not be resolved and towards the bottom of the popup menu, select the Fix project setup... option as below. Then it'll prompt to import the google play services library. Select that and you should be good to go.
How are these mipmap images different from the other familiar drawable images?
Here is my two cents in trying to explain the difference. There are two cases you deal with when working with images in Android:
You want to load an image for your device density and you are going to use it "as is", without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.
You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image's size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up. This will increase sharpness (quality) of the image.
Thus, the rule of thumb to decide where to put your image into would be:

After many many hours of researching through all of the other StackOverflow questions and answers, and trying innumerable outdated solutions, this solution managed to show notifications in these 3 scenarios:
- App is in foreground:
the notification is received by the onMessageReceived method at my MyFirebaseMessagingService class
- App has been killed (it is not running in background): the notification is sent to the notification tray automatically by FCM. When the user touches the notification the app is launched by calling the activity that has android.intent.category.LAUNCHER in the manifest. You can get the data part of the notification by using getIntent().getExtras() at the onCreate() method.
- App is in background: the notification is sent to the notification tray automatically by FCM. When the user touches the notification the app is brought to the foreground by launching the activity that has android.intent.category.LAUNCHER in the manifest. As my app has launchMode="singleTop" in that activity, the onCreate() method is not called because one activity of the same class is already created, instead the onNewIntent() method of that class is called and you get the data part of the notification there by using intent.getExtras().
Steps: 1- If you define your app's main activity like this:
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:largeHeap="true"
android:screenOrientation="portrait"
android:launchMode="singleTop">
<intent-filter>
<action android:name=".MainActivity" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
2- add these lines at the onCreate() method of your MainActivity.class
Intent i = getIntent();
Bundle extras = i.getExtras();
if (extras != null) {
for (String key : extras.keySet()) {
Object value = extras.get(key);
Log.d(Application.APPTAG, "Extras received at onCreate: Key: " + key + " Value: " + value);
}
String title = extras.getString("title");
String message = extras.getString("body");
if (message!=null && message.length()>0) {
getIntent().removeExtra("body");
showNotificationInADialog(title, message);
}
}
and these methods to the same MainActivity.class:
@Override
public void onNewIntent(Intent intent){
//called when a new intent for this class is created.
// The main case is when the app was in background, a notification arrives to the tray, and the user touches the notification
super.onNewIntent(intent);
Log.d(Application.APPTAG, "onNewIntent - starting");
Bundle extras = intent.getExtras();
if (extras != null) {
for (String key : extras.keySet()) {
Object value = extras.get(key);
Log.d(Application.APPTAG, "Extras received at onNewIntent: Key: " + key + " Value: " + value);
}
String title = extras.getString("title");
String message = extras.getString("body");
if (message!=null && message.length()>0) {
getIntent().removeExtra("body");
showNotificationInADialog(title, message);
}
}
}
private void showNotificationInADialog(String title, String message) {
// show a dialog with the provided title and message
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(title);
builder.setMessage(message);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
3- create the class MyFirebase like this:
package com.yourcompany.app;
import android.content.Intent;
import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
public class MyFirebaseMessagingService extends FirebaseMessagingService {
public MyFirebaseMessagingService() {
super();
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(Application.APPTAG, "myFirebaseMessagingService - onMessageReceived - message: " + remoteMessage);
Intent dialogIntent = new Intent(this, NotificationActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
dialogIntent.putExtra("msg", remoteMessage);
startActivity(dialogIntent);
}
}
4- create a new class NotificationActivity.class like this:
package com.yourcompany.app;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.util.Log;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.view.ContextThemeWrapper;
import com.google.firebase.messaging.RemoteMessage;
public class NotificationActivity extends AppCompatActivity {
private Activity context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = this;
Bundle extras = getIntent().getExtras();
Log.d(Application.APPTAG, "NotificationActivity - onCreate - extras: " + extras);
if (extras == null) {
context.finish();
return;
}
RemoteMessage msg = (RemoteMessage) extras.get("msg");
if (msg == null) {
context.finish();
return;
}
RemoteMessage.Notification notification = msg.getNotification();
if (notification == null) {
context.finish();
return;
}
String dialogMessage;
try {
dialogMessage = notification.getBody();
} catch (Exception e){
context.finish();
return;
}
String dialogTitle = notification.getTitle();
if (dialogTitle == null || dialogTitle.length() == 0) {
dialogTitle = "";
}
AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(context, R.style.myDialog));
builder.setTitle(dialogTitle);
builder.setMessage(dialogMessage);
builder.setPositiveButton(getResources().getString(R.string.accept), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
5- Add these lines to your app Manifest, inside your tags
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<meta-data android:name="com.google.firebase.messaging.default_notification_channel_id" android:value="@string/default_notification_channel_id"/>
<activity android:name=".NotificationActivity"
android:theme="@style/myDialog"> </activity>
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/notification_icon"/>
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/color_accent" />
6- add these lines in your Application.java onCreate() method, or in MainActivity.class onCreate() method:
// notifications channel creation
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// Create channel to show notifications.
String channelId = getResources().getString("default_channel_id");
String channelName = getResources().getString("General announcements");
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(new NotificationChannel(channelId,
channelName, NotificationManager.IMPORTANCE_LOW));
}
Done.
Now for this to work well in the 3 mentioned scenarios, you have to send the notification from the Firebase web console in the following way:
In the Notification section:
Notification Title = Title to display in the notification dialog (optional)
Notification text = Message to show to the user (required)
Then in the Target section:
App = your Android app
and in Additional Options section:
Android Notification Channel = default_channel_id
Custom Data
key: title value: (same text here than in the Title field of the Notification section)
key: body value: (same text here than in the Message field of the Notification section)
key:click_action value: .MainActivity
Sound=Disabled

I tried subtract, but the result was not consistent.
If I run df1.subtract(df2)
, not all lines of df1 are shown on the result dataframe, probably due distinct
cited on the docs.
This solved my problem:
df1.exceptAll(df2)
I had the same problem using ListAdapter
I let Android Studio implement methods for me and this is what I got:
public class CustomAdapter implements ListAdapter {
...
@Override
public void registerDataSetObserver(DataSetObserver observer) {
}
@Override
public void unregisterDataSetObserver(DataSetObserver observer) {
}
...
}
The problem is that these methods do not call super
implementations so notifyDataSetChange
is never called.
Either remove these overrides manually or add super calls and it should work again.
@Override
public void registerDataSetObserver(DataSetObserver observer) {
super.registerDataSetObserver(observer);
}
@Override
public void unregisterDataSetObserver(DataSetObserver observer) {
super.unregisterDataSetObserver(observer);
}
The key of this problem is to detect the load-more event, start an async request for data and then update the list. Also an adapter with loading indicator and other decorators is needed. In fact, the problem is very complicated in some corner cases. Just a OnScrollListener
implementation is not enough, because sometimes the items do not fill the screen.
I have written a personal package which support endless list for RecyclerView
, and also provide a async loader implementation AutoPagerFragment
which makes it very easy to get data from a multi-page source. It can load any page you want into a RecyclerView
on a custom event, not only the next page.
Here is the address: https://github.com/SphiaTower/AutoPagerRecyclerManager
The most simplest solution I have seen to supply a short execution to the UI thread is via the post() method of a view. This is needed since UI methods are not re-entrant. The method for this is:
package android.view;
public class View;
public boolean post(Runnable action);
The post() method corresponds to the SwingUtilities.invokeLater(). Unfortunately I didn't find something simple that corresponds to the SwingUtilities.invokeAndWait(), but one can build the later based on the former with a monitor and a flag.
So what you save by this is creating a handler. You simply need to find your view and then post on it. You can find your view via findViewById() if you tend to work with id-ed resources. The resulting code is very simple:
/* inside your non-UI thread */
view.post(new Runnable() {
public void run() {
/* the desired UI update */
}
});
}
Note: Compared to SwingUtilities.invokeLater() the method View.post() does return a boolean, indicating whether the view has an associated event queue. Since I used the invokeLater() resp. post() anyway only for fire and forget, I did not check the result value. Basically you should call post() only after onAttachedToWindow() has been called on the view.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.
The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

Tooltips in bootstrap are good, but there is also a very good tooltip function in jQuery UI, which you can read about here.
Example:
<label for="male" id="foo" title="Hello This Will Have Some Value">Hello...</label>
Then, assuming you have already referenced jQuery and jQueryUI libraries in your head, add a script element like this:
<script type="text/javascript">
$(document).ready(function(){
$(this).tooltip();
});
</script>
This will display the contents of the title attribute as a tooltip when you rollover any element with a title attribute.

A small static custom method in a Util
class would help:
public static int getIndex(Set<? extends Object> set, Object value) {
int result = 0;
for (Object entry:set) {
if (entry.equals(value)) return result;
result++;
}
return -1;
}
If you need/want one class that is a Set
and offers a getIndex()
method, I strongly suggest to implement a new Set
and use the decorator pattern:
public class IndexAwareSet<T> implements Set {
private Set<T> set;
public IndexAwareSet(Set<T> set) {
this.set = set;
}
// ... implement all methods from Set and delegate to the internal Set
public int getIndex(T entry) {
int result = 0;
for (T entry:set) {
if (entry.equals(value)) return result;
result++;
}
return -1;
}
}
Cache the query in a global variable when it is not available.
Create a webpage to force the cache to be reloaded when you update it.

{
List<T> randomizedList = new List<T>();
Random rnd = new Random();
while (list.Count > 0)
{
int index = rnd.Next(0, list.Count); //pick a random item from the master list
randomizedList.Add(list[index]); //place it at the end of the randomized list
list.RemoveAt(index);
}
return randomizedList;

ClientID
Get the client id generated in the page that uses Master page. As Master page is UserControl type, It will have its own Id and it treats the page as Child control and generates a different id with prefix like ctrl_
.
This can be resolved by using <%= ControlName.ClientID %>
in a page and can be assigned to any string or a javascript variables that can be referred later.
var myHidden=document.getElementById('<%= hdntxtbxTaksit.ClientID %>');
ASP.Net 4.0 +
ClientIDMode Property
Use this property to control how you want to generate the ID for you. For your case setting ClientIDMode="static" in page level will resolve the problem. The same thing can be applied at control level as well.
You need to Generate a new SSH key and add it to your ssh-agent. For That you should follow this link.
After you create the public key and add it to your github account, you should use Built-in (not Native) option under Setting-> Version Control -> Git -> SSH executable in your Intellij Idea.
I believe you need to group by , in that day of the month of the year . so why not using TRUNK_DATE functions . The way it works is described below :
Group By DATE_TRUNC('day' , 'occurred_at_time')
The below query helps to get the row number in oracle,
SELECT ROWNUM AS SNO,ID,NAME,EMAIL,BRANCH FROM student WHERE NAME LIKE '%ram%';
Alternatively , you can use vectors to get a writable char* as demonstrated below;
//this handles memory manipulations and is more convenient
string str;
vector <char> writable (str.begin (), str.end) ;
writable .push_back ('\0');
char* cstring = &writable[0] //or &*writable.begin ()
//Goodluck
here is one that work with both " and ' and you easily add others at the start.
("|')(?:\\\1|[^\1])*?\1
it uses the backreference (\1) match exactley what is in the first group (" or ').
Try using urllib2:

A loading indicator is simply an animated image (.gif) that is displayed until the completed event is called on the AJAX request. http://ajaxload.info/ offers many options for generating loading images that you can overlay on your modals. To my knowledge, Bootstrap does not provide the functionality built-in.

With the help of the attribute selector you can select the input element with the corresponding value. Then you have to set the attribute explicitly, using .attr
:
var value = 5;
$("input[name=mygroup][value=" + value + "]").attr('checked', 'checked');
Since jQuery 1.6, you can also use the .prop
method with a boolean value (this should be the preferred method):
$("input[name=mygroup][value=" + value + "]").prop('checked', true);
Remember you first need to remove checked attribute from any of radio buttons under one radio buttons group only then you will be able to add checked property / attribute to one of the radio button in that radio buttons group.
Code To Remove Checked Attribute from all radio buttons of one radio button group -
$('[name="radioSelectionName"]').removeAttr('checked');
To provide another approach similar to the answer by @IvanCollantes.
It works by additionally filtering the required checkboxes by name. I also simplified the code a bit and checks for a default checked
checkbox.
jQuery(function($) {_x000D_
var requiredCheckboxes = $(':checkbox[required]');_x000D_
requiredCheckboxes.on('change', function(e) {_x000D_
var checkboxGroup = requiredCheckboxes.filter('[name="' + $(this).attr('name') + '"]');_x000D_
var isChecked = checkboxGroup.is(':checked');_x000D_
checkboxGroup.prop('required', !isChecked);_x000D_
});_x000D_
requiredCheckboxes.trigger('change');_x000D_

I agree withe the other answers regarding the correct way to loop through the files. However the OP asked:
The code above doesn't work, do you know why?
Yes!
An excellent article What is the difference between test, [ and [[ ?] explains in detail that among other differences, you cannot use expression matching
or pattern matching
within the test
command (which is shorthand for [
)
Feature new test [[ old test [ Example Pattern matching = (or ==) (not available) [[ $name = a* ]] || echo "name does not start with an 'a': $name" Regular Expression =~ (not available) [[ $(date) =~ ^Fri\ ...\ 13 ]] && echo "It's Friday the 13th!" matching
So this is the reason your script fails. If the OP is interested in an answer with the [[
syntax (which has the disadvantage of not being supported on as many platforms as the [
command), I would be happy to edit my answer to include it.
EDIT: Any protips for how to format the data in the answer as a table would be helpful!
For startswith, you can use indexOf:
if(str.indexOf('Hello') == 0) {
...
and you can do the maths based on string length to determine 'endswith'.
if(str.lastIndexOf('Hello') == str.length - 'Hello'.length) {
All official methods only tells whether a device is open for network or not,
If your device is connected to Wifi but Wifi is not connected to internet then these method will fail (Which happen many time), No inbuilt network detection method will tell about this scenario, so created Async Callback class which will return in onConnectionSuccess and onConnectionFail
new CheckNetworkConnection(this, new CheckNetworkConnection.OnConnectionCallback() {
@Override
public void onConnectionSuccess() {
Toast.makeText(context, "onSuccess()", toast.LENGTH_SHORT).show();
}
@Override
public void onConnectionFail(String msg) {
Toast.makeText(context, "onFail()", toast.LENGTH_SHORT).show();
}
}).execute();

Another option which hasn't been mentioned is to use which
:
length(which(z))
Just to actually provide some context on the "which is faster question", it's always easiest just to test yourself. I made the vector much larger for comparison:
z <- sample(c(TRUE,FALSE),1000000,rep=TRUE)
system.time(sum(z))
user system elapsed
0.03 0.00 0.03
system.time(length(z[z==TRUE]))
user system elapsed
0.75 0.07 0.83
system.time(length(which(z)))
user system elapsed
1.34 0.28 1.64
system.time(table(z)["TRUE"])
user system elapsed
10.62 0.52 11.19
So clearly using sum
is the best approach in this case. You may also want to check for NA
values as Marek suggested.
Just to add a note regarding NA values and the which
function:
> which(c(T, F, NA, NULL, T, F))
[1] 1 4
> which(!c(T, F, NA, NULL, T, F))
[1] 2 5
Note that which only checks for logical TRUE
, so it essentially ignores non-logical values.
I'm afraid Aularon didn't provide enough steps to complete the process. With a little trial and error, I was able to successfully enable Gzipping on my dedicated WHM server.
Below are the steps:
Run EasyApache within WHM, select Deflate within the Exhaustive Options list, and rebuild the server.
Once done, goto Services Configuration >> Apache Configuration >> Include Editor >> Post VirtualHost Include, select All Versions, and then paste the mod_headers.c and mod_headers.c code (listed above in Aularon's post) on top of on another within the input field.
Once saved, I was seeing a 75.36% data savings on average! You can run a before and after test by using this HTTP Compression tool to see your own results: http://www.whatsmyip.org/http_compression/
Hope this works for you all!
How about
wc -l file.txt | cut -d' ' -f1

JS:
<div onclick="location.href='url'">content</div>
jQuery:
$("div").click(function(){
window.location=$(this).find("a").attr("href"); return false;
});
Make sure to use cursor:pointer
for these DIVs
You can access values in the $_POST
array by their key. $_POST is an associative array, so to access taskOption
you would use $_POST['taskOption'];
.
Make sure to check if it exists in the $_POST array before proceeding though.
<form method="post" action="process.php">
<select name="taskOption">
<option value="first">First</option>
<option value="second">Second</option>
<option value="third">Third</option>
</select>
<input type="submit" value="Submit the form"/>
</form>
process.php
<?php
$option = isset($_POST['taskOption']) ? $_POST['taskOption'] : false;
if ($option) {
echo htmlentities($_POST['taskOption'], ENT_QUOTES, "UTF-8");
} else {
echo "task option is required";
exit;
}
Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.
To get the string representation using at least 4 digits:
int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

//check for trivial IPs
if(str=="::")return ar;
//parse
var sar=str.split(':');
var slen=sar.length;
if(slen>8)slen=8;
var j=0;
for(var i=0;i<slen;i++){
//this is a "::", switch to end-run mode
if(i && sar[i]==""){j=9-slen+i;continue;}
ar[j]=parseInt("0x0"+sar[i]);
j++;
}
return ar;
}
function ipcnvfrom6(ip6)
{
var ip6=parseIp6(ip6);
var ip4=(ip6[6]>>8)+"."+(ip6[6]&0xff)+"."+(ip6[7]>>8)+"."+(ip6[7]&0xff);
return ip4;
}
alert(ipcnvfrom6("::C0A8:4A07"));

Multi-line comments are easily breakable. What if you have the following in a simple calculator program?
operation = ''
print("Pick an operation: +-*/")
# Get user input here
Try to comment that with a multi-line comment:
/*
operation = ''
print("Pick an operation: +-*/")
# Get user input here
*/
Oops, your string contains the end comment delimiter.
You can float:right in react native using flex:
<View style={{flex: 1, flexDirection: 'row'}}>
<View style={{width: 50, height: 50, backgroundColor: 'powderblue'}} />
<View style={{width: 50, height: 50, backgroundColor: 'skyblue'}} />
<View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
</View>

Try this also, that is remove new { } and replace it with string.
<%: Html.TextBoxFor(x => x.Age,"0") %>
Use +
for string concatenation as:
section = 'C_type'
new_section = 'Sec_' + section
On ipython or jupyter notebook, you can use all the above mentioned ways, but i go with
my_func?
or
?my_func
for quick summary of both method signature and docstring.
I avoid using

(as commented by @rohan) for docstring and use it only to check the source code
I ran into this on Python 3 and found this question (and solution). When opening a file, Python 3 supports the encoding keyword to automatically handle the encoding.
Without it, the BOM is included in the read result:
>>> f = open('file', mode='r')
>>> f.read()
'\ufefftest'
Giving the correct encoding, the BOM is omitted in the result:
>>> f = open('file', mode='r', encoding='utf-8-sig')
>>> f.read()
'test'
Just my 2 cents.
on the web site box, you have selected .NETFramework 4.5 and it doesn show, so click there and choose the 3.5...i hope it helps.
In the html file there are three input boxes with userid,username,department respectively.
These inputboxes are used to get the input from the user.
The user can add any number of inputs to the page.

One common idiom is:
char* c = source;
while (*c) putchar(*c++);
A few notes:
*c++
increments c
and returns the dereferenced old value of c
.printf("%s")
prints a null-terminated string, not a char. This is the cause of your access violation.For Ionic you can face multiple issues as @Karl mentioned. The solution which works flawlessly for ionic lazy loaded pages is:
// pipes.ts content (it can have multiple pipes inside, just remember to
use @Pipe function before each class)
import { PipeTransform, Pipe } from "@angular/core";
@Pipe({ name: "toArray" })
export class toArrayPipe implements PipeTransform {
transform(value, args: string[]): any {
if (!value) return value;
let keys = [];
for (let key in value) {
keys.push({ key: key, value: value[key] });
}
return keys;
}
}
// pipes.module.ts content
import { NgModule } from "@angular/core";
import { IonicModule } from "ionic-angular";
import { toArrayPipe } from "./pipes";
@NgModule({
declarations: [toArrayPipe],
imports: [IonicModule],
exports: [toArrayPipe]
})
export class PipesModule {}
Include PipesModule into app.module and @NgModule imports section
import { PipesModule } from "../pipes/pipes.module";
@NgModule({
imports: [
PipesModule
]
});
Include PipesModule in each of your .module.ts where you want to use custom pipes. Don't forget to add it into imports section. // Example. file: pages/my-custom-page/my-custom-page.module.ts
import { PipesModule } from "../../pipes/pipes.module";
@NgModule({
imports: [
PipesModule
]
})
Thats it. Now you can use your custom pipe in your template. Ex.
<div *ngFor="let prop of myObject | toArray">{{ prop.key }}</div>
Here is a part of the response that tells you if an element is in the viewport. You may need to check if there is nothing on top of it using elementFromPoint, but it's a bit longer.
function isInViewport(element) {
var rect = element.getBoundingClientRect();
var windowHeight = window.innerHeight || document.documentElement.clientHeight;
var windowWidth = window.innerWidth || document.documentElement.clientWidth;
return rect.bottom > 0 && rect.top < windowHeight && rect.right > 0 && rect.left < windowWidth;
}
I got the same error for windows 8.The issue is because of an environment variable of your system path is missing . Add "C:\Windows\System32\" value to your system PATH variable.
You can use the with_fileglob
loop for this:
- copy:
src: "{{ item }}"
dest: /etc/fooapp/
owner: root
mode: 600
with_fileglob:
- /playbooks/files/fooapp/*
Please, ckeck this simple example. You can get values in select2 multi.
var values = $('#id-select2-multi').val();
console.log(values);
I think this is the easiest way to loop in react js
<ul>
{yourarray.map((item)=><li>{item}</li>)}
</ul>

In your database what is the type of "IDNO"? You may need to escape the sql here:
$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
I had the same problem, just use console.log(...)

The top answer works in the case that you want to examine the state immediately prior to the failed command.
However, the question asks how to examine the state of the failed container itself. In my situation, the failed command is a build that takes several hours, so rewinding prior to the failed command and running it again takes a long time and is not very helpful.
The solution here is to find the container that failed:
$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6934ada98de6 42e0228751b3 "/bin/sh -c './utils/" 24 minutes ago Exited (1) About a minute ago sleepy_bell
Commit it to an image:
$ docker commit 6934ada98de6
sha256:7015687976a478e0e94b60fa496d319cdf4ec847bcd612aecf869a72336e6b83
And then run the image [if necessary, running bash]:
$ docker run -it 7015687976a4 [bash -il]
Now you are actually looking at the state of the build at the time that it failed, instead of at the time before running the command that caused the failure.
If you are using phpmyadmin then this feature is already there.
You should put your processing into the class constructor or an OnInit
hook method.

I encountered the same problem... I solved it by creating a custom axios instance. and using that to make a authenticated delete request..
const token = localStorage.getItem('token');
const request = axios.create({
headers: {
Authorization: token
}
});
await request.delete('<your route>, { data: { <your data> }});
I realize this is just adding to the already huge amount of answers for this question, but thought it deserved mentioning that, although not perfect, a combination of the answers given by: @Stefano, @MichaelRibbons, and @IvanFerrerVilla has provided a decent bit of success, when neither of them on their own was very successful.
The obvious answer to this is "that's what the JLS says."
Thinking about why that is, consider that this behavior can be useful in certain cases. Let's say you want to check a string against a set of other strings, but the number of other strings can vary.
So you have something like this:
for(String s : myStrings) {
check(aString.contains(s));
}
where some s
's are empty strings.
If the empty string is interpreted as "no input," and if your purpose here is ensure that aString
contains all the "inputs" in myStrings
, then it is misleading for the empty string to return false
. All strings contain it because it is nothing. To say they didn't contain it would imply that the empty string had some substance that was not captured in the string, which is false.

It is possible to use the semless attribute right now, here i found a german article http://www.solife.cc/blog/html5-iframe-attribut-seamless-beispiele.html

You have to use the window.postMessage method to communicate between the parent and the iframe.
It can be achieved using JS. Here is a 'one-line' solution using elastic.js:

I don't understand how can datenwolf`s index generation can be correct. But still I find his solution rather clear. This is what I get after some thinking:
inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
int curRow = r * sectors;
int nextRow = (r+1) * sectors;
indices.push_back(curRow + s);
indices.push_back(nextRow + s);
indices.push_back(nextRow + (s+1));
indices.push_back(curRow + s);
indices.push_back(nextRow + (s+1));
indices.push_back(curRow + (s+1));
}
void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
float radius, unsigned int rings, unsigned int sectors)
{
float const R = 1./(float)(rings-1);
float const S = 1./(float)(sectors-1);
for(int r = 0; r < rings; ++r) {
for(int s = 0; s < sectors; ++s) {
float const y = sin( -M_PI_2 + M_PI * r * R );
float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );
texcoords.push_back(vec2(s*S, r*R));
vertices.push_back(vec3(x,y,z) * radius);
push_indices(indices, sectors, r, s);
}
}
}

Python
import numpy as np
import imageio
image = imageio.imread(r'[image-path]', as_gray=True)
# getting the threshold value
thresholdValue = np.mean(image)
# getting the dimensions of the image
xDim, yDim = image.shape
# turn the image into a black and white image
for i in range(xDim):
for j in range(yDim):
if (image[i][j] > thresholdValue):
image[i][j] = 255
else:
image[i][j] = 0
Update since Java 8: Java 8 uses a self-balanced tree for collision-handling, improving the worst case from O(n) to O(log n) for lookup. The use of a self-balanced tree was introduced in Java 8 as an improvement over chaining (used until java 7), which uses a linked-list, and has a worst case of O(n) for lookup (as it needs to traverse the list)
To answer the second part of your question, insertion is done by mapping a given element to a given index in the underlying array of the hashmap, however, when a collision occurs, all elements must still be preserved (stored in a secondary data-structure, and not just replaced in the underlying array). This is usually done by making each array-component (slot) be a secondary datastructure (aka bucket), and the element is added to the bucket residing on the given array-index (if the key does not already exist in the bucket, in which case it is replaced).
During lookup, the key is hashed to it's corresponding array-index, and search is performed for an element matching the (exact) key in the given bucket. Because the bucket does not need to handle collisions (compares keys directly), this solves the problem of collisions, but does so at the cost of having to perform insertion and lookup on the secondary datastructure. The key point is that in a hashmap, both the key and the value is stored, and so even if the hash collides, keys are compared directly for equality (in the bucket), and thus can be uniquely identified in the bucket.
Collission-handling brings the worst-case performance of insertion and lookup from O(1) in the case of no collission-handling to O(n) for chaining (a linked-list is used as secondary datastructure) and O(log n) for self-balanced tree.
References:
Java 8 has come with the following improvements/changes of HashMap objects in case of high collisions.
The alternative String hash function added in Java 7 has been removed.
Buckets containing a large number of colliding keys will store their entries in a balanced tree instead of a linked list after certain threshold is reached.
Above changes ensure performance of O(log(n)) in worst case scenarios (https://www.nagarro.com/en/blog/post/24/performance-improvement-for-hashmap-in-java-8)
Another Git-related answer:
The source of the problem might be the Git server. If all else fails, try doing dpkg-reconfigure locales
(or whatever is appropriate for your distribution) on the server.
Audience. Functional testing is to assure members of the team producing the software that it does what they expect. Acceptance testing is to assure the consumer that it meets their needs.
Scope. Functional testing only tests the functionality of one component at a time. Acceptance testing covers any aspect of the product that matters to the consumer enough to test before accepting the software (i.e., anything worth the time or money it will take to test it to determine its acceptability).
Software can pass functional testing, integration testing, and system testing; only to fail acceptance tests when the customer discovers that the features just don't meet their needs. This would usually imply that someone screwed up on the spec. Software could also fail some functional tests, but pass acceptance testing because the customer is willing to deal with some functional bugs as long as the software does the core things they need acceptably well (beta software will often be accepted by a subset of users before it is completely functional).
In Python 3.8+ you can use .read()
in a while
loop:
with open("somefile.txt") as f:
while chunk := f.read(8192):
do_something(chunk)
Of course, you can use any chunk size you want, you don't have to use 8192
(2**13
) bytes. Unless your file's size happens to be a multiple of your chunk size, the last chunk will be smaller than your chunk size.
Using a generator expression:
def magic(numbers):
digits = ''.join(str(n) for n in numbers)
return int(digits)
On Windows 7, I had to delete %HOMEPATH%/pip
.
In my case i was overriding the existing app store build with my build.I removed the same and its working now.
You can consider using a very small, dependency-free library like Not. Solves all problems:
// at the basic level it supports primitives
let number = 10
let array = []
not('number', 10) // returns false
not('number', []) // throws error
// so you need to define your own:
let not = Object.create(Not)
not.defineType({
primitive: 'number',
type: 'integer',
pass: function(candidate) {
// pre-ECMA6
return candidate.toFixed(0) === candidate.toString()
// ECMA6
return Number.isInteger(candidate)
}
})
not.not('integer', 4.4) // gives error message
not.is('integer', 4.4) // returns false
not.is('integer', 8) // returns true
If you make it a habit, your code will be much stronger. Typescript solves part of the problem but doesn't work at runtime, which is also important.
function test (string, boolean) {
// any of these below will throw errors to protect you
not('string', string)
not('boolean', boolean)
// continue with your code.
}
The right way is to fix the overflow, but....
You can give yourself a bigger stack:-
using System.Threading;
Thread T = new Thread(threadDelegate, stackSizeInBytes);
T.Start();
You can use System.Diagnostics.StackTrace FrameCount property to count the frames you've used and throw your own exception when a frame limit is reached.
Or, you can calculate the size of the stack remaining and throw your own exception when it falls below a threshold:-
class Program
{
static int n;
static int topOfStack;
const int stackSize = 1000000; // Default?
// The func is 76 bytes, but we need space to unwind the exception.
const int spaceRequired = 18*1024;
unsafe static void Main(string[] args)
{
int var;
topOfStack = (int)&var;
n=0;
recurse();
}
unsafe static void recurse()
{
int remaining;
remaining = stackSize - (topOfStack - (int)&remaining);
if (remaining < spaceRequired)
throw new Exception("Cheese");
n++;
recurse();
}
}
Just catch the Cheese. ;)
yes..in JAVA
System.out.println(Integer.SIZE/8); //gives you 4.
System.out.println(Integer.SIZE); //gives you 32.
//Similary for Byte,Long,Double....
Use:
Question question = Question.Role;
int value = Convert.ToInt32(question);
Yes VBA is the way to go.
But, if you don't need to have a cell with formula that auto-counts/updates the number of cells with a particular colour, an alternative is simply to use the 'Find and Replace' function and format the cell to have the appropriate colour fill.
Hitting 'Find All' will give you the total number of cells found at the bottom left of the dialogue box.
This becomes especially useful if your search range is massive. The VBA script will be very slow but the 'Find and Replace' function will still be very quick.
No, the action should be the name of php file. With on click you may only call JavaScript. And please be aware the hiding your code from the user undermines trust. JS runs on the browser so some trust is needed.
There is no better way I know of. Bash knows only status codes (integers) and strings written to the stdout.
What you did with the iteration is not wrong from what I can make of it based on the question. It gives you a valid array of String objects. Like mentioned in another answer it is however easier to use the toArray() method available for the ArrayList object => http://docs.oracle.com/javase/1.5.0/docs/api/java/util/ArrayList.html#toArray%28%29
Just a side note. If you would iterate your dsf array properly and print each element on its own you would get valid output. Like this:
for(String str : dsf){
System.out.println(str);
}
What you probably tried to do was print the complete Array object at once since that would give an object memory address like you got in your question. If you see that kind of output you need to provide a toString() method for the object you're printing.
Your code is fine. There's no problem with returning Strings
in this manner.
In Java, a String
is a reference to an immutable object. This, coupled with garbage collection, takes care of much of the potential complexity: you can simply pass a String
around without worrying that it would disapper on you, or that someone somewhere would modify it.
If you don't mind me making a couple of stylistic suggestions, I'd modify the code like so:
public String time_to_string(long t) // time in milliseconds
{
if (t < 0)
{
return "-";
}
else
{
int secs = (int)(t/1000);
int mins = secs/60;
secs = secs - (mins * 60);
return String.format("%d:%02d", mins, secs);
}
}
As you can see, I've pushed the variable declarations as far down as I could (this is the preferred style in C++ and Java). I've also eliminated ans
and have replaced the mix of string concatenation and String.format()
with a single call to String.format()
.
You can use the -i privatekeyfilelocation
in case you are using a private key instead of password based.
This is work for me 100% :
let data:Observable<any> = this.http.post(url, postData);
data.subscribe((data) => {
let d = data.json();
console.log(d);
console.log("result = " + d.result);
console.log("url = " + d.image_url);
loader.dismiss();
});
this works flawlessly for me. insert any code before or after the "do until" loop. In your case, put the 5 lines (time1= & time2= & "do until" loop) at the end inside your do loop
sub whatever()
Dim time1, time2
time1 = Now
time2 = Now + TimeValue("0:00:01")
Do Until time1 >= time2
DoEvents
time1 = Now()
Loop
End sub
You need to do the following
git fetch -p
This will update the local database of remote branches.
As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

Also, TokenInput is an interesting one. First, it does not depend on jQuery-UI, second its config is very smooth.
The only issue I had it does not support free-tagging natively. So, I have to return the query-string back to client as a part of response JSON.
As @culithay mentioned in the comment, TokenInput supports a lot of features to customize. And highlight of some feature that the others don't have:
Thanks culithay for the input.
Understanding the language syntax is important when considering clarity of code. Consider copying a character string, for example with post-increment:
char a[256] = "Hello world!";
char b[256];
int i = 0;
do {
b[i] = a[i];
} while (a[i++]);
We want the loop to execute through encountering the zero character (which tests false) at the end of the string. That requires testing the value pre-increment and also incrementing the index. But not necessarily in that order - a way to code this with the pre-increment would be:
int i = -1;
do {
++i;
b[i] = a[i];
} while (a[i]);
It is a matter of taste which is clearer and if the machine has a handfull of registers both should have identical execution time, even if a[i] is a function that is expensive or has side-effects. A significant difference might be the exit value of the index.
var idx = myArray.reduce( function( cur, val, index ){
if( val.hello === "stevie" && cur === -1 ) {
return index;
}
return cur;
}, -1 );
It's better to use PathVariable annotation if you still want to get the uri which was called.
@PostMapping("/pub/{action:a|b|c}")
public JSONObject handlexxx(@PathVariable String action, @RequestBody String reqStr){
...
}
or parse it from request object.
You should be using java.sql.Timestamp instead of java.util.Date. Also using a PreparedStatement will save you worrying about the formatting.

For anyone who is facing this problem with Spring Boot 2
by default spring boot was using hibernate 5.3.x version, I have added following property in my pom.xml
<hibernate.version>5.4.2.Final</hibernate.version>
and error was gone. Reason for error is already explained in posts above
Correct me if wrong...I think request does persist between consecutive pages..
Think you traverse from page 1--> page 2-->page 3.
You have some value set in the request object using setAttribute from page 1, which you retrieve in page 2 using getAttribute,then if you try setting something again in same request object to retrieve it in page 3 then it fails giving you null value as "the request that created the JSP, and the request that gets generated when the JSP is submitted are completely different requests and any attributes placed on the first one will not be available on the second".
I mean something like this in page 2 fails:
Where as the same thing has worked in case of page 1 like:
So I think I would need to proceed with either of the two options suggested by Phill.

Solution using just POST - no $_SESSION
page1.php
<form action="page2.php" method="post">
<textarea name="textarea1" id="textarea1"></textarea><br />
<input type="submit" value="submit" />
</form>
page2.php
<?php
// this page outputs the contents of the textarea if posted
$textarea1 = ""; // set var to avoid errors
if(isset($_POST['textarea1'])){
$textarea1 = $_POST['textarea1']
}
?>
<textarea><?php echo $textarea1;?></textarea>
Solution using $_SESSION and POST
page1.php
<?php
session_start(); // needs to be before anything else on page to use $_SESSION
$textarea1 = "";
if(isset($_POST['textarea1'])){
$_SESSION['textarea1'] = $_POST['textarea1'];
}
?>
<form action="page1.php" method="post">
<textarea name="textarea1" id="textarea1"></textarea><br />
<input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>
page2.php
<?php
session_start(); // needs to be before anything else on page to use $_SESSION
// this page outputs the textarea1 from the session IF it exists
$textarea1 = ""; // set var to avoid errors
if(isset($_SESSION['textarea1'])){
$textarea1 = $_SESSION['textarea1']
}
?>
<textarea><?php echo $textarea1;?></textarea>
WARNING!!! - This contains no validation!!!
You can do that very easily if you can use Perl.
perl -ne 'if (/abc/) { $abc = 1; next }; print "Found in $ARGV\n" if ($abc && /efg/); }' yourfilename.txt
You can do that with a single regular expression too, but that involves taking the entire contents of the file into a single string, which might end up taking up too much memory with large files. For completeness, here is that method:
perl -e '@lines = <>; $content = join("", @lines); print "Found in $ARGV\n" if ($content =~ /abc.*efg/s);' yourfilename.txt
It is also possible to use Object.freeze
on you class(es6)/constructor function(es5) object to make it immutable:
class MyConstants {}
MyConstants.staticValue = 3;
MyConstants.staticMethod = function() {
return 4;
}
Object.freeze(MyConstants);
// after the freeze, any attempts of altering the MyConstants class will have no result
// (either trying to alter, add or delete a property)
MyConstants.staticValue === 3; // true
MyConstants.staticValue = 55; // will have no effect
MyConstants.staticValue === 3; // true
MyConstants.otherStaticValue = "other" // will have no effect
MyConstants.otherStaticValue === undefined // true
delete MyConstants.staticMethod // false
typeof(MyConstants.staticMethod) === "function" // true
Trying to alter the class will give you a soft-fail (won't throw any errors, it will simply have no effect).
AssertionError is an Unchecked Exception which rises explicitly by programmer or by API Developer to indicate that assert statement fails.
assert(x>10);
Output:
AssertionError
If x is not greater than 10 then you will get runtime exception saying AssertionError.
I recently solved this problem by using table-caption, though I cannot say if it is recommended. The other answers didn't seem to workout in my case.

I am not sure whether the database backup file, you trying to restore, is coming from the same environment as you trying to restore it onto.
Remember that destination path of .mdf and .ldf files lives with the backup file itself.
If this is not a case, that means the backup file is coming from a different environment from your current hosting one, make sure that .mdf and .ldf file path is the same (exists) as on your machine, relocate these otherwise. (Mostly a case of restoring db in Docker image)
The way how to do it: In Databases -> Restore database -> [Files] option -> (Check "Relocate all files to folder" - mostly default path is populated on your hosting environment already)
Simple and with little changes. And also hide load more when entire list is loaded.
jsFiddle here.

$('#myList li:lt(3)').show();
$('#showLess').hide();
var items = 25;
var shown = 3;
$('#loadMore').click(function () {
$('#showLess').show();
shown = $('#myList li:visible').size()+5;
if(shown< items) {$('#myList li:lt('+shown+')').show();}
else {$('#myList li:lt('+items+')').show();
$('#loadMore').hide();
}
});
$('#showLess').click(function () {
$('#myList li').not(':lt(3)').hide();
});
});
