Extend the DOM Element, Handle the Error, and Degrade Gracefully
Below I use the prototype function to wrap the native DOM play function, grab its promise, and then degrade to a play button if the browser throws an exception. This extension addresses the shortcoming of the browser and is plug-n-play in any page with knowledge of the target element(s).
// JavaScript
// Wrap the native DOM audio element play function and handle any autoplay errors
Audio.prototype.play = (function(play) {
return function () {
var audio = this,
args = arguments,
promise = play.apply(audio, args);
if (promise !== undefined) {
promise.catch(_ => {
// Autoplay was prevented. This is optional, but add a button to start playing.
var el = document.createElement("button");
el.innerHTML = "Play";
el.addEventListener("click", function(){play.apply(audio, args);});
this.parentNode.insertBefore(el, this.nextSibling)
});
}
};
})(Audio.prototype.play);
// Try automatically playing our audio via script. This would normally trigger and error.
document.getElementById('MyAudioElement').play()
<!-- HTML -->
<audio id="MyAudioElement" autoplay>
<source src="https://www.w3schools.com/html/horse.ogg" type="audio/ogg">
<source src="https://www.w3schools.com/html/horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
<div class='block1'>
<p style="float:left">text</p>
<div class='block2' style="float:right">block2</div>
<p style="float:left; clear:left">text2</p>
</div>
You can clear:both
or clear:left
depending on the exact context.
Also, you will have to play around with width
to get it to work correctly...
Very late answer, but you can simply use:
import time
today = time.strftime("%Y-%m-%d")
# 2021-02-18
Try using this code, it worked for me:
z-index: unset;
I have encountered the same problem today and found that beyond that 4000 character limit, I had to split the dynamic query into two strings and concatenate them when executing the query.
DECLARE @Query NVARCHAR(max);
DECLARE @Query2 NVARCHAR(max);
SET @Query = 'SELECT...' -- some of the query gets set here
SET @Query2 = '...' -- more query gets added on, etc.
EXEC (@Query + @Query2)
When I inspected the problem, I have noticed that the following dll were missing in the output folder. The simple solution is copy Entityframework.dll and Entityframework.sqlserver.dll with the app.config to the output folder if the application is on debug mode. At the same time change, the build option parameter "Copy to output folder" of app.config to copy always. This will solve your problem.
They are identical according to sizeof()
In the absence of any reason to worry about "faster", always optimize for the human. Which makes more sense to the human reader?
Remember that your suggestions makes it difficult for clients to communicate with the server. They need to understand your innovative solution and encrypt the data accordingly, this model is not so good for public API (unless you are amazon\yahoo\google..).
Anyways, if you must encrypt the body content I would suggest you to check out existing standards and solutions like:
XML encryption (W3C standard)
Add the following CSS:
For the parent div:
style="display: flex;"
For child div:
style="align-items: stretch;"
You might need to use a character by character (getc()) loop to ensure you have no buffer overflows and don't truncate the input.
I have this simple solution I have been using and its works.
In App/Exceptions/Handler.php
Add this at top:
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
Then inside the render method
public function render($request, Exception $exception)
{
.......
if ($exception instanceof NotFoundHttpException){
$segment = $request->segments();
//eg. http://site.dev/member/profile
//module => member
// view => member.index
//where member.index is the root of your angular app could be anything :)
if(head($segment) != 'api' && $module = $segment[0]){
return response(view("$module.index"), 404);
}
return response()->fail('not_found', $exception->getCode());
}
.......
return parent::render($request, $exception);
}
If you use the static method and load the properties file from the classpath folder so you can use the below code :
//load a properties file from class path, inside static method
Properties prop = new Properties();
prop.load(Classname.class.getClassLoader().getResourceAsStream("foo.properties"));
refer to my code, hope helpful for you:
Runtime runtime = Runtime.getRuntime();
Process proc = runtime.exec("mount");
InputStream is = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
String line;
String mount = new String();
BufferedReader br = new BufferedReader(isr);
while ((line = br.readLine()) != null) {
if (line.contains("secure")) continue;
if (line.contains("asec")) continue;
if (line.contains("fat")) {//TF card
String columns[] = line.split(" ");
if (columns != null && columns.length > 1) {
mount = mount.concat("*" + columns[1] + "\n");
}
} else if (line.contains("fuse")) {//internal storage
String columns[] = line.split(" ");
if (columns != null && columns.length > 1) {
mount = mount.concat(columns[1] + "\n");
}
}
}
txtView.setText(mount);
I know this question was answered a while ago, but when dealing with large data sets, nested queries can be costly. Here is a different solution where the nested query will only be ran once, instead of for each row returned.
SELECT
Orders.OrderNumber,
LineItems.Quantity,
LineItems.Description
FROM
Orders
INNER JOIN (
SELECT
Orders.OrderNumber,
Max(LineItem.LineItemID) AS LineItemID
FROM
Orders INNER JOIN LineItems
ON Orders.OrderNumber = LineItems.OrderNumber
GROUP BY Orders.OrderNumber
) AS Items ON Orders.OrderNumber = Items.OrderNumber
INNER JOIN LineItems
ON Items.LineItemID = LineItems.LineItemID
Expanding on Brian Camire's Answer:
Using =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,""))
with CTRL+SHIFT+ENTER
will include blank cells in the calculation. Blank cells will be evaluated as 0 which results in a lower median value. The same is true if using the average funtion. If you don't want to include blank cells in the calculation, use a nested if statement like so:
=MEDIAN(IF($A$1:$A$6="Airline",IF($B$1:$B$6<>"",$B$1:$B$6)))
Don't forget to press CTRL+SHIFT+ENTER
to treat the formula as an "array formula".
Not need to change all config in file /opt/lampp/etc/extra/httpd-xampp.conf.
The only thing you need to change is the Require local
It's kinda obvious what Require local means so just change to Require all granted
Require all granted
Solution
from Require local
to Require all granted
For raw speed, use C. For power, use C++. For .NET compatibility, use C#.
They're all pretty complex as languages go; C through decades of gradual accretion, C++ through years of more rapid enhancement, and C# through the power of Microsoft.
If you must use the label for the formControl
. Like the Ant Design Checkbox. It may throw this error while running tests. You can use ngDefaultControl
<label nz-checkbox formControlName="isEnabled" ngDefaultControl>
Hello
</label>
<nz-switch nzSize="small" formControlName="mandatory" ngDefaultControl></nz-switch>
Note that both pcolor and "surf + view(2)" do not show the last row and the last column of your 2D data.
On the other hand, using imagesc, you have to be careful with the axes. The surf and the imagesc examples in gevang's answer only (almost -- apart from the last row and column) correspond to each other because the 2D sinc function is symmetric.
To illustrate these 2 points, I produced the figure below with the following code:
[x, y] = meshgrid(1:10,1:5);
z = x.^3 + y.^3;
subplot(3,1,1)
imagesc(flipud(z)), axis equal tight, colorbar
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc')
subplot(3,1,2)
surf(x,y,z,'EdgeColor','None'), view(2), axis equal tight, colorbar
title('surf with view(2)')
subplot(3,1,3)
imagesc(flipud(z)), axis equal tight, colorbar
axis([0.5 9.5 1.5 5.5])
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc cropped')
colormap jet
As you can see the 10th row and 5th column are missing in the surf plot. (You can also see this in images in the other answers.)
Note how you can use the "set(gca, 'YTick'..." (and Xtick) command to set the x and y tick labels properly if x and y are not 1:1:N.
Also note that imagesc only makes sense if your z data correspond to xs and ys are (each) equally spaced. If not you can use surf (and possibly duplicate the last column and row and one more "(end,end)" value -- although that's a kind of a dirty approach).
I wrote generic version of index sort.
template <class RAIter, class Compare>
void argsort(RAIter iterBegin, RAIter iterEnd, Compare comp,
std::vector<size_t>& indexes) {
std::vector< std::pair<size_t,RAIter> > pv ;
pv.reserve(iterEnd - iterBegin) ;
RAIter iter ;
size_t k ;
for (iter = iterBegin, k = 0 ; iter != iterEnd ; iter++, k++) {
pv.push_back( std::pair<int,RAIter>(k,iter) ) ;
}
std::sort(pv.begin(), pv.end(),
[&comp](const std::pair<size_t,RAIter>& a, const std::pair<size_t,RAIter>& b) -> bool
{ return comp(*a.second, *b.second) ; }) ;
indexes.resize(pv.size()) ;
std::transform(pv.begin(), pv.end(), indexes.begin(),
[](const std::pair<size_t,RAIter>& a) -> size_t { return a.first ; }) ;
}
Usage is the same as that of std::sort except for an index container to receive sorted indexes. testing:
int a[] = { 3, 1, 0, 4 } ;
std::vector<size_t> indexes ;
argsort(a, a + sizeof(a) / sizeof(a[0]), std::less<int>(), indexes) ;
for (size_t i : indexes) printf("%d\n", int(i)) ;
you should get 2 1 0 3. for the compilers without c++0x support, replace the lamba expression as a class template:
template <class RAIter, class Compare>
class PairComp {
public:
Compare comp ;
PairComp(Compare comp_) : comp(comp_) {}
bool operator() (const std::pair<size_t,RAIter>& a,
const std::pair<size_t,RAIter>& b) const { return comp(*a.second, *b.second) ; }
} ;
and rewrite std::sort as
std::sort(pv.begin(), pv.end(), PairComp(comp)()) ;
I have given different ways to create DataFrame from text file
val conf = new SparkConf().setAppName(appName).setMaster("local")
val sc = SparkContext(conf)
val file = sc.textFile("C:\\vikas\\spark\\Interview\\text.txt")
val fileToDf = file.map(_.split(",")).map{case Array(a,b,c) =>
(a,b.toInt,c)}.toDF("name","age","city")
fileToDf.foreach(println(_))
import org.apache.spark.sql.SparkSession
val sparkSess =
SparkSession.builder().appName("SparkSessionZipsExample")
.config(conf).getOrCreate()
val df = sparkSess.read.option("header",
"false").csv("C:\\vikas\\spark\\Interview\\text.txt")
df.show()
import org.apache.spark.sql.types._
val schemaString = "name age city"
val fields = schemaString.split(" ").map(fieldName => StructField(fieldName,

val schema = StructType(fields)
val dfWithSchema = sparkSess.read.option("header",

I agree with @haha on this one, for the most part. But there are several cross-browser related issues with using the "float:right" and could ultimately give you more of a headache than you want. If you know what the widths are going to be for each column use a float:left on both and save yourself the trouble. Another thing you can incorporate into your methodology is build column classes into your CSS.
So try something like this:
CSS
.col-wrapper{width:960px; margin:0 auto;}
.col{margin:0 10px; float:left; display:inline;}
.col-670{width:670px;}
.col-250{width:250px;}
HTML
<div class="col-wrapper">
<div class="col col-670">[Page Content]</div>
<div class="col col-250">[Page Sidebar]</div>
</div>
I was having the same problem until I read Jon Skeet's answer about the debugger displaying a single backslash with a double backslash even though the string may have a single backslash. I was not aware of that. So I changed my code from
text2 = text1.Replace(@"\\", @"/");
to
text2 = text1.Replace(@"\", @"/");
and that solved the problem. Note: I'm interfacing and R.Net which uses single forward slashes in path strings.
You should use the following:
$('#gentab').on('click', 'a.tabclick', function(event) {
event.preventDefault();
var liId = $(this).closest("li").attr("id");
alert(liId);
});
This will attach your event to any anchors within the #gentab
element,
reducing the scope of having to check the whole document
element tree and increasing efficiency.
In many case It is java facet problem ,jdk or jre or jsp version is difference than maven project face.
In case you already have a "Configuration" with many migrations and want to keep this as is, you can always create a new "Configuration" class, give it another name, like
class MyNewContextConfiguration : DbMigrationsConfiguration<MyNewDbContext>
{
...
}
then just issue the command
Add-Migration -ConfigurationTypeName MyNewContextConfiguration InitialMigrationName
and EF will scaffold the migration without problems. Finally update your database, from now on, EF will complain if you don't tell him which configuration you want to update:
Update-Database -ConfigurationTypeName MyNewContextConfiguration
Done.
You don't need to deal with Enable-Migrations as it will complain "Configuration" already exists, and renaming your existing Configuration class will bring issues to the migration history.
You can target different databases, or the same one, all configurations will share the __MigrationHistory table nicely.
You can do it like this:
For example , i want to modify my service endpoint address at runtime so i have the following ServiceEndpoint.xml file.
<?xml version="1.0" encoding="utf-8" ?>
<Services>
<Service name="FileTransferService">
<Endpoints>
<Endpoint name="ep1" address="http://localhost:8080/FileTransferService.svc" />
</Endpoints>
</Service>
</Services>
For reading your xml :
var doc = new XmlDocument();
doc.Load(FileTransferConstants.Constants.SERVICE_ENDPOINTS_XMLPATH);
XmlNodeList endPoints = doc.SelectNodes("/Services/Service/Endpoints");
foreach (XmlNode endPoint in endPoints)
{
foreach (XmlNode child in endPoint)
{
if (child.Attributes["name"].Value.Equals("ep1"))
{
var adressAttribute = child.Attributes["address"];
if (!ReferenceEquals(null, adressAttribute))
{
address = adressAttribute.Value;
}
}
}
}
Then get your web.config file of your client at runtime and assign the service endpoint address as:
Configuration wConfig = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap { ExeConfigFilename = @"C:\FileTransferWebsite\web.config" }, ConfigurationUserLevel.None);
ServiceModelSectionGroup wServiceSection = ServiceModelSectionGroup.GetSectionGroup(wConfig);
ClientSection wClientSection = wServiceSection.Client;
wClientSection.Endpoints[0].Address = new Uri(address);
wConfig.Save();
I resolve this problem on NodeJS like this:
var util = require('util');
// Our circular object
var obj = {foo: {bar: null}, a:{a:{a:{a:{a:{a:{a:{hi: 'Yo!'}}}}}}}};
obj.foo.bar = obj;
// Generate almost valid JS object definition code (typeof string)
var str = util.inspect(b, {depth: null});
// Fix code to the valid state (in this example it is not required, but my object was huge and complex, and I needed this for my case)
str = str
.replace(/<Buffer[ \w\.]+>/ig, '"buffer"')
.replace(/\[Function]/ig, 'function(){}')
.replace(/\[Circular]/ig, '"Circular"')
.replace(/\{ \[Function: ([\w]+)]/ig, '{ $1: function $1 () {},')
.replace(/\[Function: ([\w]+)]/ig, 'function $1(){}')
.replace(/(\w+): ([\w :]+GMT\+[\w \(\)]+),/ig, '$1: new Date("$2"),')
.replace(/(\S+): ,/ig, '$1: null,');
// Create function to eval stringifyed code
var foo = new Function('return ' + str + ';');
// And have fun
console.log(JSON.stringify(foo(), null, 4));
You had thead
in your selector, but there is no thead
in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr
class to the th
, not vice-versa (although your comment seems to contradict what you wrote up above).
$('tr th').each(function(index){ if($('tr td').eq(index).attr('class') != ''){ // get the class of the td var tdClass = $('tr td').eq(index).attr('class'); // add it to this th $(this).addClass(tdClass ); } });
The simplest solution would be to add the following code on the top of the file. And than you can use all full Chrome console api as you would normally.
console = chrome.extension.getBackgroundPage().console;
// for instance, console.assert(1!=1) will return assertion error
// console.log("msg") ==> prints msg
// etc
Looks like someone finally did it, it is a tiny bit ugly - but here it is:

It involves some kernel recompiling, and a bit of editing, and you loose partial functionality (the MDC?) .. but it's done.
Personally though, now that I see the "true cost", I would probably put together a little adapter on a Teency or something - assuming that Android can talk to serial devices via USB. But that's based on the fact that I have a samsung, and would require a special cable to make a USB connection anyway - no extra pain to have a little device on the end, if I have to carry the damn cable around anyway.
The OP is asking about whether it is possible to add an Attribute to an Entity class for a Unique Key. The short answer is that it IS possible, but not an out-of-the-box feature from the EF Core Team. If you'd like to use an Attribute to add Unique Keys to your Entity Framework Core entity classes, you can do what I've posted here
public class Company
{
[Required]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public Guid CompanyId { get; set; }
[Required]
[UniqueKey(groupId: "1", order: 0)]
[StringLength(100, MinimumLength = 1)]
public string CompanyName { get; set; }
[Required]
[UniqueKey(groupId: "1", order: 1)]
[StringLength(100, MinimumLength = 1)]
public string CompanyLocation { get; set; }
}
The easiest way is to use history.go(-1);
Try this:
<a href="#" onclick="history.go(-1)">Go Back</a>

I was getting this error message due to my EC2 instance's clock being out of sync.
I was able to fix on Ubuntu using this:
sudo ntpdate ntp.ubuntu.com
sudo apt-get install ntp
I use a utility named msgbox.exe from here: http://www.paulsadowski.com/WSH/cmdprogs.htm
I got this error using Spring Boot (in Mozilla),
because I was just testing some basic controller -> service -> repository communication by directly returning some entities from the database to the browser (as JSON).
I forgot to put data in the database, so my method wasn't returning anything... and I got this error.
Now that I put some data in my db, it works fine (the error is removed). :D
The answer is "No, one can't find the median of an arbitrary, unsorted dataset in linear time". The best one can do as a general rule (as far as I know) is Median of Medians (to get a decent start), followed by Quickselect. Ref: [https://en.wikipedia.org/wiki/Median_of_medians][1]
This may not be the exact definition but I'll give you an example: If you were to create a random number taking it from the system time, here using the unsigned variable is beneficial as there is large scope for random numbers as signed numbers give both positive and negative numbers. As the system time can't be negative we use unsigned variable(Only positive numbers) and we have more wide range of random numbers.
The following works for me:
git diff master:foo foo
In the past, it may have been:
git diff foo master:foo
Just wanted to leave this here so I don't lose it. The advantage to this one is that it's usable in InterfaceBuilder, which is a HUGE advantage. This is taken from another question that I asked:
static Server *instance;
+ (Server *)instance { return instance; }
+ (id)hiddenAlloc
{
return [super alloc];
}
+ (id)alloc
{
return [[self instance] retain];
}
+ (void)initialize
{
static BOOL initialized = NO;
if(!initialized)
{
initialized = YES;
instance = [[Server hiddenAlloc] init];
}
}
- (id) init
{
if (instance)
return self;
self = [super init];
if (self != nil) {
// whatever
}
return self;
}
As soon as signed and unsigned ints are mixed in an expression things start to get messy and you probably will lose information. Restricting Java to signed ints only really clears things up. I’m glad I don’t have to worry about the whole signed/unsigned business, though I sometimes do miss the 8th bit in a byte.
You can use Dagger to create a reference of that receiver.
First provide it:
@Provides
@YourScope
fun providesReceiver(): NotificationReceiver{
return NotificationReceiver()
}
Then inject it where you need (using constructor
or field injection
)
and simply pass it to registerReceiver
.
Also put it in try/catch
block too.
Use the -p flag and add /udp
suffix to the port number.
-p 53160:53160/udp
Full command
sudo docker run -p 53160:53160 \
-p 53160:53160/udp -p 58846:58846 \
-p 8112:8112 -t -i aostanin/deluge /start.sh
If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.
You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile
(EXPOSE does not publish the port):
EXPOSE 8285/udp
Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

iii) CREATE DATABASE db_name;
iv) Exit MySQL server, press CTRL + D.
5) Add the MySQL Database Connection to your Application:
i) Navigate to the settings.py file and replace the current DATABASES lines with the following:
# Database
# https://docs.djangoproject.com/en/2.0/ref/settings/#databases
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/etc/mysql/my.cnf',
},
}
}
...
ii) Next, let’s edit the config file so that it has your MySQL credentials. Use vi as sudo to edit the file and add the following information:
sudo vi /etc/mysql/my.cnf
database = db_name
user = db_user
password = db_password
default-character-set = utf8
6) Once the file has been edited, we need to restart MySQL for the changes to take effect :
systemctl daemon-reload
systemctl restart mysql
7) Test MySQL Connection to Application:
python manage.py runserver your-server-ip:8000
Try the following-sibling
axis (following-sibling::td
).
These are ranked in order of difficulty to break your hidden info.
Store in cleartext
Store encrypted using a symmetric key
Using the Android Keystore
Store encrypted using asymmetric keys
source: Where is the best place to store a password in your Android app
The Keystore itself is encrypted using the user’s own lockscreen pin/password, hence, when the device screen is locked the Keystore is unavailable. Keep this in mind if you have a background service that could need to access your application secrets.
source: Simple use the Android Keystore to store passwords and other sensitive information
For example, if we had an array of numbers:
let numbers = [2, 4, 6, 8, 9, 10]
We could find the first odd number like this:
let firstOdd = numbers.index { $0 % 2 == 1 }
That will send back 4 as an optional integer, because the first odd number (9) is at index four.
You should simply return your object, and shouldn't be concerned about whether its XML or JSON. It is the client responsibility to request JSON or XML from the web api. For example, If you make a call using Internet explorer then the default format requested will be Json and the Web API will return Json. But if you make the request through google chrome, the default request format is XML and you will get XML back.
If you make a request using Fiddler then you can specify the Accept header to be either Json or XML.
Accept: application/xml
You may wanna see this article: Content Negotiation in ASP.NET MVC4 Web API Beta – Part 1
EDIT: based on your edited question with code:
Simple return list of string, instead of converting it to XML. try it using Fiddler.
public List<string> Get(int tenantID, string dataType, string ActionName)
{
List<string> SQLResult = MyWebSite_DataProvidor.DB.spReturnXMLData("SELECT * FROM vwContactListing FOR XML AUTO, ELEMENTS").ToList();
return SQLResult;
}
For example if your list is like:
List<string> list = new List<string>();
list.Add("Test1");
list.Add("Test2");
list.Add("Test3");
return list;
and you specify Accept: application/xml
the output will be:
<ArrayOfstring xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<string>Test1</string>
<string>Test2</string>
<string>Test3</string>
</ArrayOfstring>
and if you specify 'Accept: application/json' in the request then the output will be:
[
"Test1",
"Test2",
"Test3"
]
So let the client request the content type, instead of you sending the customized xml.
Technique 2:
DECLARE @p_date DATETIME
SET @p_date = CONVERT( DATETIME, '14 AUG 2008', 106 )
SELECT *
FROM table1
WHERE DATEDIFF( d, column_datetime, @p_date ) = 0
If the column_datetime field is not indexed, and is unlikely to be (or the index is unlikely to be used) then using DATEDIFF() is shorter.
You may store the parameters for the blob detector in a file, but this is not necessary. Example:
// set up the parameters (check the defaults in opencv's code in blobdetector.cpp)
cv::SimpleBlobDetector::Params params;
params.minDistBetweenBlobs = 50.0f;
params.filterByInertia = false;
params.filterByConvexity = false;
params.filterByColor = false;
params.filterByCircularity = false;
params.filterByArea = true;
params.minArea = 20.0f;
params.maxArea = 500.0f;
// ... any other params you don't want default value
// set up and create the detector using the parameters
cv::SimpleBlobDetector blob_detector(params);
// or cv::Ptr<cv::SimpleBlobDetector> detector = cv::SimpleBlobDetector::create(params)
// detect!
vector<cv::KeyPoint> keypoints;
blob_detector.detect(image, keypoints);
// extract the x y coordinates of the keypoints:
for (int i=0; i<keypoints.size(); i++){
float X = keypoints[i].pt.x;
float Y = keypoints[i].pt.y;
}
I personally prefer this pattern which is slightly clearer and simpler, at the expense of an extra variable:
for (auto it = m.cbegin(), next_it = it; it != m.cend(); it = next_it)
{
++next_it;
if (must_delete)
{
m.erase(it);
}
}
Advantages of this approach:
it
and next_it
remain fixed throughout the iteration, allowing you to easily add additional statements referring to them without headscratching over whether they will work as intended (except of course that you cannot use it
after erasing it).The search query
model lives in the scope defined by the ng-controller="whatever"
directive. So if you want to bind the query model to <title>
, you have to move the ngController
declaration to an HTML element that is a common parent to both the body and title elements:
<html ng-app="phonecatApp" ng-controller="PhoneListCtrl">
That seems to work for me:
<html>
<head><style>
#monkey {color:blue}
#ape {color:purple}
</style></head>
<body>
<span id="monkey" onclick="changeid()">
fruit
</span>
<script>
function changeid ()
{
var e = document.getElementById("monkey");
e.id = "ape";
}
</script>
</body>
</html>
The expected behaviour is to change the colour of the word "fruit".

Use git format-patch
to slice out the part of the commit you care about and git am
to apply it to another branch
git format-patch <sha> -- path/to/file
git checkout other-branch
git am *.patch
In JavaScript you can get the current date and time using the Date object;
var now = new Date();
This will get the local client machine time
Example for jquery LINK
If you are using jQuery DatePicker you can apply it on any textfield like this:
$( "#datepicker" ).datepicker({dateFormat:"yy/mm/dd"}).datepicker("setDate",new Date());
I was just having this issue with my own program. I turned out that the value I was searching for was not in my reference table. I fixed my reference table, and then the error went away.
Async is suitable if your script doesn’t contains DOM manipulation and other scripts doesn’t depend upon on this. Eg: bootstrap cdn,jquery
Defer is suitable if your script contains DOM manipulation and other scripts depend upon on this.
Eg: <script src=”createfirst.js”> //let this will create element <script src=”showfirst.js”> //after createfirst create element it will show that.
Thus make it:
Eg: <script defer src=”createfirst.js”> //let this will create element <script defer src=”showfirst.js”>
//after createfirst create element it will
This will execute scripts in order.
But if i made:
Eg: <script async src=”createfirst.js”> //let this will create element <script defer src=”showfirst.js”>
//after createfirst create element it will
Then, this code might result unexpected results. Coz: if html parser access createfirst script.It won’t stop DOM creation and starts downloading code from src .Once src got resolved/code got downloaded, it will execute immediately parallel with DOM.
What if showfirst.js execute first than createfirst.js.This might be possible if createfirst takes long time (Assume after DOM parsing finished).Then, showfirst will execute immediately.
Implement an interface to call your function in your method
interface IMyInterface
{
void MyinterfaceMethod();
}
IMyInterface MyObj = obj as IMyInterface;
if ( MyObj != null)
{
MyMethod(IMyInterface MyObj );
}
Check out this one-liner plugin that scales a background image responsively.
All you need to do is:
1. Include the library:
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery-backstretch/2.0.4/jquery.backstretch.min.js"></script>
2. Call the method:
$.backstretch("http://dl.dropbox.com/u/515046/www/garfield-interior.jpg");
I used it for a simple "under construction website" site I had and it worked perfectly.
I added ExportToStream so the csv didn't have to save to the hard drive first.
public Stream ExportToStream()
{
MemoryStream stream = new MemoryStream();
StreamWriter writer = new StreamWriter(stream);
writer.Write(Export(true));
writer.Flush();
stream.Position = 0;
return stream;
}
I will recommended best answer as
<?php
echo 'Hello ' . htmlspecialchars($_GET["name"]) . '!';

Assuming the user entered http://example.com/?name=Hannes
The above example will output:

When you add the python directory to the path (Computer > Properties > Advanced System Settings > Advanced > Environmental Variables > System Variables > Path > Edit), remember to add a semicolon, then make sure that you are adding the precise directory where the file "python.exe" is stored (e.g. C:\Python\Python27 if that is where "python.exe" is stored). Then restart the command prompt.
As opposed to what's written on the chosen answer, you don't need root and it is possible to get the APKs of the installed apps, which is how I've done it on my app (here). Example:
List<PackageInfo> packages=getPackageManager().getInstalledPackages(0);
Then, for each of the items of the list, you can access packageInfo.applicationInfo.sourceDir, which is the full path of the APK of the installed app.
UITableView is a subclass of UIScrollView, so you can also use:
[mainTableView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];
Or
[mainTableView setContentOffset:CGPointZero animated:YES];
And in Swift:
mainTableView.setContentOffset(CGPointZero, animated:true)
And in Swift 3 & above:
mainTableView.setContentOffset(.zero, animated: true)
I often use a blank label as the TargetControlID. ex. <asp:Label ID="lblghost" runat="server" Text="" />
I've seen two things that cause the click event not fire:
1. you have to remove the OKControlID (as others have mentioned)
2. If you are using field validators you should add CausesValidation="false" on the button.
Both scenarios behaved the same way for me.
You're in the less
program, which makes the output of git log
scrollable.
Type q to exit this screen. Type h to get help.
If you don't want to read the output in a pager and want it to be just printed to the terminal define the environment variable GIT_PAGER
to cat
or set core.pager
to cat
(execute git config --global core.pager cat
).
Since my edit to Mike G's answer to modernize the code was rejected 3 to 2 as
This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer
I'm reposting my edit as a separate answer here. This edit removes the JSONRepresentation
dependency with NSJSONSerialization
as Rob's comment with 15 upvotes suggests.
NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
[[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"], nil];
NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];
NSLog(@"jsonRequest is %@", jsonRequest);
NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil]; //TODO handle error
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (connection) {
receivedData = [[NSMutableData data] retain];
}
The receivedData is then handled by:
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSDictionary *question = [jsonDict objectForKey:@"question"];
If you just want the node closest to the text you're searching for, you could use this:
$('*:contains("my text"):last');
This will even work if your HTML looks like this:
<p> blah blah <strong>my <em>text</em></strong></p>
Using the above selector will find the <strong>
tag, since that's the last tag which contains that entire string.
You can use git filter-branch for that. e.g.
git filter-branch --parent-filter \
'if test $GIT_COMMIT != <sha1ofB>; then cat; fi'
This results in AB-C throwing away the commit log of A.
I'm surprised no one is using the Scrolloff
option which keeps the cursor in the middle of the page.
Try it with:
:set so=999
It's the first recommended method on the Vim wiki and works well.
If you're getting an error like this:

We can not bind this to setTimeout()
, as it always execute with global object (Window), if you want to access this
context in the callback function then by using bind()
to the callback function we can achieve as:
setTimeout(function(){
this.methodName();
}.bind(this), 2000);
Consolidating Jason Pratt's and the community wiki answers, with a look at the results of different methods of binding:
Especially note how adding the binding function as a class method works, but the referencing scope is incorrect.

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
This question is a bit old now (don't know why I keep hitting old questions today) but I was thinking about BOOST_FUSION_ADAPT_STRUCT which introduces compile-time reflection.
It is up to you to map this to run-time reflection of course, and it won't be too easy, but it is possible in this direction, while it would not be in the reverse :)
I really think a macro to encapsulate the BOOST_FUSION_ADAPT_STRUCT
one could generate the necessary methods to get the runtime behavior.
I think what you may be after is the CSS property touch-action. You just need a CSS rule like this:
html, body {touch-action: none;}
You will see it has pretty good support (https://caniuse.com/#feat=mdn-css_properties_touch-action_none), including Safari, as well as back to IE10.
I found a more elegant solution, combining "inline-block" to avoid using float and the hacky clear:both. It still requires nested divs tho, which isnt very semantic but it just works...
div.outer{
display:inline-block;
position:relative;
left:50%;
}
div.inner{
position:relative;
left:-50%;
}
Hope it helps!
These specific lines are the usual wrapper for jQuery plugins:
"...to make sure that your plugin doesn't collide with other libraries that might use the dollar sign, it's a best practice to pass jQuery to a self executing function (closure) that maps it to the dollar sign so it can't be overwritten by another library in the scope of its execution."
(function( $ ){
$.fn.myPlugin = function() {
// Do your awesome plugin stuff here
};
})( jQuery );
Try this It is working for me..
The syntax is GetFiles(string path, string searchPattern);
var filePath = Server.MapPath("~/App_Data/");
string[] filePaths = Directory.GetFiles(@filePath, "*.*");
This code will return all the files inside App_Data
folder.
The second parameter . indicates the searchPattern with File Extension where the first * is for file name and second is for format of the file or File Extension like (*.png - any file name with .png format.
You can use the CellMouseEnter and CellMouseLeave to track the row number that the mouse is currently hovering over.
Then use a ContextMenu object to display you popup menu, customised for the current row.
Here's a quick and dirty example of what I mean...
private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
ContextMenu m = new ContextMenu();
m.MenuItems.Add(new MenuItem("Cut"));
m.MenuItems.Add(new MenuItem("Copy"));
m.MenuItems.Add(new MenuItem("Paste"));
int currentMouseOverRow = dataGridView1.HitTest(e.X,e.Y).RowIndex;
if (currentMouseOverRow >= 0)
{
m.MenuItems.Add(new MenuItem(string.Format("Do something to row {0}", currentMouseOverRow.ToString())));
}
m.Show(dataGridView1, new Point(e.X, e.Y));
}
}
Use request.args.get(param)
, for example:
http://10.1.1.1:5000/login?username=alex&password=pw1
@app.route('/login', methods=['GET', 'POST'])
def login():
username = request.args.get('username')
print(username)
password = request.args.get('password')
print(password)
If your application is a web service, Directory.CurrentDirectory
doesn't work.
Use System.IO.Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "yourFileName.txt"))
instead.
insert into bookmarks (users_id, lessoninfo_id)
select 1, 167
EXCEPT
select user_id, lessoninfo_id
from bookmarks
where user_id=1
and lessoninfo_id=167;
This is the fastest way.
For some other SQL engines, you can use a Dummy table containing 1 record. e.g:
select 1, 167 from ONE_RECORD_DUMMY_TABLE
Create a view that selects only non-NULL
columns and create the UNIQUE INDEX
on the view:
CREATE VIEW myview
AS
SELECT *
FROM mytable
WHERE mycolumn IS NOT NULL
CREATE UNIQUE INDEX ux_myview_mycolumn ON myview (mycolumn)
Note that you'll need to perform INSERT
's and UPDATE
's on the view instead of table.
You may do it with an INSTEAD OF
trigger:
CREATE TRIGGER trg_mytable_insert ON mytable
INSTEAD OF INSERT
AS
BEGIN
INSERT
INTO myview
SELECT *
FROM inserted
END
^
matches position just before the first character of the string$
matches position just after the last character of the string.
matches a single character. Does not matter what character it is, except newline*
matches preceding match zero or more timesSo, ^.*$
means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.
Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones
and Matthew's last name is Jones
. The pattern ^Matt.*Jones$
will match Matthew's last name is Jones
. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.
Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.

The accepted answer provided a good starting point, but if you resize the frame, change the column widths, or even change the table data, the headers will get messed up in various ways. Every other example I've seen has similar issues, or imposes some serious restrictions on the table's layout.
I think I've finally got all these problems solved, though. It took a lot of CSS, but the final product is about as reliable and easy to use as a normal table.
Here's an example that has all the required features to replicate the table referenced by the OP: jsFiddle
The colors and borders would have to be changed to make it identical to the reference. Information on how to make those kinds of changes is provided in the CSS comments.

If you want to use SelectedValue then your combobox must be databound.
To set up the combobox:
ComboBox1.DataSource = GetMailItems()
ComboBox1.DisplayMember = "Name"
ComboBox1.ValueMember = "ID"
To get the data:
Function GetMailItems() As List(Of MailItem)
Dim mailItems = New List(Of MailItem)
Command = New MySqlCommand("SELECT * FROM `maillist` WHERE l_id = '" & id & "'", connection)
Command.CommandTimeout = 30
Reader = Command.ExecuteReader()
If Reader.HasRows = True Then
While Reader.Read()
mailItems.Add(New MailItem(Reader("ID"), Reader("name")))
End While
End If
Return mailItems
End Function
Public Class MailItem
Public Sub New(ByVal id As Integer, ByVal name As String)
mID = id
mName = name
End Sub
Private mID As Integer
Public Property ID() As Integer
Get
Return mID
End Get
Set(ByVal value As Integer)
mID = value
End Set
End Property
Private mName As String
Public Property Name() As String
Get
Return mName
End Get
Set(ByVal value As String)
mName = value
End Set
End Property
End Class
Can you use date as a factor?
Yes, but you probably shouldn't.
...or should you use
as.Date
on a date column?
Yes.
Which leads us to this:
library(scales)
df$Month <- as.Date(df$Month)
ggplot(df, aes(x = Month, y = AvgVisits)) +
geom_bar(stat = "identity") +
theme_bw() +
labs(x = "Month", y = "Average Visits per User") +
scale_x_date(labels = date_format("%m-%Y"))
in which I've added stat = "identity"
to your geom_bar
call.
In addition, the message about the binwidth wasn't an error. An error will actually say "Error" in it, and similarly a warning will always say "Warning" in it. Otherwise it's just a message.
URL url = new URL(yourUrl, "/api/v1/status.xml");
According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:
URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");
Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html
System.gc();
Runs the garbage collector.
Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick reuse. When control returns from the method call, the Java Virtual Machine has made a best effort to reclaim space from all discarded objects.
Not recommended.
Edit: I wrote the original response in 2009. It's now 2015.
Garbage collectors have gotten steadily better in the ~20 years Java's been around. At this point, if you're manually calling the garbage collector, you may want to consider other approaches:
Note that the wmode=transparent fix only works if it's first so

I find that when i choose option of Project->Properties->Linker->System->SubSystem->Console(/subsystem:console), and then make sure include the function : int _tmain(int argc,_TCHAR* argv[]){return 0} all of the compiling ,linking and running will be ok;
The accepted answer was fundamentally flawed, it has since been deleted. The correct answer is:
function scrolled(e) {
if (myDiv.offsetHeight + myDiv.scrollTop >= myDiv.scrollHeight) {
scrolledToBottom(e);
}
}
Tested this in Firefox, Chrome and Opera. It works.
I think the better answer for this questions is
array_diff()
because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.
Whereas
array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.
It's quite possible that someone will provide a truly detailed answer here, but I've always found this post from Robert Sosinski to be a great explanation of the subtleties between blocks, procs & lambdas.
I should add that I believe the post I'm linking to is specific to ruby 1.8. Some things have changed in ruby 1.9, such as block variables being local to the block. In 1.8, you'd get something like the following:
>> a = "Hello"
=> "Hello"
>> 1.times { |a| a = "Goodbye" }
=> 1
>> a
=> "Goodbye"
Whereas 1.9 would give you:
>> a = "Hello"
=> "Hello"
>> 1.times { |a| a = "Goodbye" }
=> 1
>> a
=> "Hello"
I don't have 1.9 on this machine so the above might have an error in it.
You can migrate to XDocument instead of XmlDocument and then use Linq if you prefer that syntax. Something like:
var q = (from myConfig in xDoc.Elements("MyConfiguration")
select myConfig.Attribute("SuperString").Value)
.First();
Toward this same directions, I'm posting a client and server snipets that send Excel Files using WebApi, c# 4:
public static void SetFile(String serviceUrl, byte[] fileArray, String fileName)
{
try
{
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
using (var content = new MultipartFormDataContent())
{
var fileContent = new ByteArrayContent(fileArray);//(System.IO.File.ReadAllBytes(fileName));
fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = fileName
};
content.Add(fileContent);
var result = client.PostAsync(serviceUrl, content).Result;
}
}
}
catch (Exception e)
{
//Log the exception
}
}
And the server webapi controller:
public Task<IEnumerable<string>> Post()
{
if (Request.Content.IsMimeMultipartContent())
{
string fullPath = HttpContext.Current.Server.MapPath("~/uploads");
MyMultipartFormDataStreamProvider streamProvider = new MyMultipartFormDataStreamProvider(fullPath);
var task = Request.Content.ReadAsMultipartAsync(streamProvider).ContinueWith(t =>
{
if (t.IsFaulted || t.IsCanceled)
throw new HttpResponseException(HttpStatusCode.InternalServerError);
var fileInfo = streamProvider.FileData.Select(i =>
{
var info = new FileInfo(i.LocalFileName);
return "File uploaded as " + info.FullName + " (" + info.Length + ")";
});
return fileInfo;
});
return task;
}
else
{
throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotAcceptable, "Invalid Request!"));
}
}
And the Custom MyMultipartFormDataStreamProvider, needed to customize the Filename:
PS: I took this code from another post http://www.codeguru.com/csharp/.net/uploading-files-asynchronously-using-asp.net-web-api.htm
public class MyMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
public MyMultipartFormDataStreamProvider(string path)
: base(path)
{
}
public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
{
string fileName;
if (!string.IsNullOrWhiteSpace(headers.ContentDisposition.FileName))
{
fileName = headers.ContentDisposition.FileName;
}
else
{
fileName = Guid.NewGuid().ToString() + ".data";
}
return fileName.Replace("\"", string.Empty);
}
}
You can define a Range, the size of your array and use it's value property:
Sub PrintArray(Data, SheetName As String, intStartRow As Integer, intStartCol As Integer)
Dim oWorksheet As Worksheet
Dim rngCopyTo As Range
Set oWorksheet = ActiveWorkbook.Worksheets(SheetName)
' size of array
Dim intEndRow As Integer
Dim intEndCol As Integer
intEndRow = UBound(Data, 1)
intEndCol = UBound(Data, 2)
Set rngCopyTo = oWorksheet.Range(oWorksheet.Cells(intStartRow, intStartCol), oWorksheet.Cells(intEndRow, intEndCol))
rngCopyTo.Value = Data
End Sub
to insert a new column at a given location (0 <= loc <= amount of columns) in a data frame, just use Dataframe.insert:
DataFrame.insert(loc, column, value)
Therefore, if you want to add the column e at the end of a data frame called df, you can use:
e = [-0.335485, -1.166658, -0.385571]
DataFrame.insert(loc=len(df.columns), column='e', value=e)
value can be a Series, an integer (in which case all cells get filled with this one value), or an array-like structure
https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.insert.html
For setting value in hidden field do in the following way:
@Html.HiddenFor(model => model.title,
new { id= "natureOfVisitField", Value = @Model.title})
It will work

The Host
Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host
header does not match any of the configured virtual hosts.
That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).
Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.
This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.
Although the webserver would know the hostname from Server Name Indication, the Host
header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host
header is still valid (and necessary).
Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host
header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD
RESOURCE
and PROTOCOL VERSION
and at least the Host
header, like this:
GET /someresource.html HTTP/1.1
Host: www.example.com
In the MDN Documentation on the "Host" header they actually phrase it like this:
A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.
As mentioned by Darrel Miller, the complete specs can be found in RFC7230.
You need to set
WindowStyle="None"
, AllowsTransparency="True"
and optionally ResizeMode="NoResize"
and then set the Style
property of the window to your custom window style, where you design the appearance of the window (title bar, buttons, border) to anything you want and display the window contents in a ContentPresenter
.
This seems to be a good article on how you can achieve this, but there are many other articles on the internet.
For me, an issue where json_encode would return null encoding of an entity was because my jsonSerialize implementation fetched entire objects for related entities; I solved the issue by making sure that I fetched the ID of the related/associated entity and called ->toArray() when there were more than one entity associated with the object to be json serialized. Note, I'm speaking about cases where one implements JsonSerializable
on entities.
If you don't want to lose the columns you shift past the end of your dataframe, simply append the required number first:
offset = 5
DF = DF.append([np.nan for x in range(offset)])
DF = DF.shift(periods=offset)
DF = DF.reset_index() #Only works if sequential index
I think the project you are looking for is: https://github.com/sarxos/webcam-capture (I'm the author)
There is an example working exactly as you've described - after it's run, the window appear where, after you press "Start" button, you can see live image from webcam device and save it to file after you click on "Snapshot" (source code available, please note that FPS counter in the corner can be disabled):
The project is portable (WinXP, Win7, Win8, Linux, Mac, Raspberry Pi) and does not require any additional software to be installed on the PC.
API is really nice and easy to learn. Example how to capture single image and save it to PNG file:
Webcam webcam = Webcam.getDefault();
webcam.open();
ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));
Queries should look like :
SHOW TABLES
SHOW TABLES FROM mydatabase
SHOW TABLES FROM mydatabase LIKE "tab%"
Things from the MySQL documentation in square brackets [] are optional.
Assuming $WORKING_DIR
is set to the directory... this one-liner should do it:
if [ -d "$WORKING_DIR" ]; then rm -Rf $WORKING_DIR; fi
(otherwise just replace with your directory)
The following works with Java 7/8, secure urls, and shows how to add a cookie to your request as well. Note this is mostly a direct copy of this other great answer on this page, but added the cookie example, and clarification in that it works with secure urls as well ;-)
If you need to connect to a server with an invalid certificate or self signed certificate, this will throw security errors unless you import the certificate. If you need this functionality, you could consider the approach detailed in this answer to this related question on StackOverflow.

What helped me was
1) To view all available remote branches (e.g. 'remote-branch-name')
git branch -r
2) Create a local branch using remote branch name
git fetch && git checkout 'remote-branch-name'

This can be done using the unique function in ufp.path module.
import ufp.path
ufp.path.unique('./test.ext')
if current path exists 'test.ext' file. ufp.path.unique function return './test (d1).ext'.
I was able to use this site to easily download and install curl on my Windows machine. It took all of 30 seconds. I'm using Windows 7 (w/ Admin privelages), so I downloaded curl-7.37.0-win64.msi from http://curl.haxx.se/download.html.
Also, don't forget to restart your console/terminal after you install curl, otherwise you will get the same error messages.
All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)
Based on this related answer, you are looking at a list that looks like: A-Z
, a-z
, 0-9
, -
, .
, _
, ~
, :
, /
, ?
, #
, [
, ]
, @
, !
, $
, &
, '
, (
, )
, *
, +
, ,
, ;
, %
, and =
. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. %
can only be used in conjunction with url encoding as in %20
), the RFC has all of these specifics.
I face same problem when install Scipy under ubuntu.
I had to use command:
$ sudo apt-get install libatlas-base-dev gfortran
$ sudo pip3 install scipy
You can get more details here Installing SciPy with pip
Sorry don't know how to do it under OS X Yosemite.
I'm having same problem. I try to install office 2010 64bit on windows 7 64 bit and then install 2007 Office System Driver : Data Connectivity Components.
after that, visual studio 2008 can opens a connection to an MS-Access 2007 database file.
You may need to call frame.repaint()
as well to force the frame to actually redraw itself. I've had issues before where I tried to repaint a component and it wasn't updating what was displayed until the parent's repaint() method was called.
$('input:radio[checked=false]');
this will also work
input:radio:not(:checked)
or
:radio:not(:checked)
For people who needs to validate years earlier than year 1900, following should do the trick. Actually this is same as the above answer given by [@OammieR][1]
BUT with years including 1800 - 1899.
/^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((18|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((18|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$/
Hope this helps someone who needs to validate years earlier than 1900, such as 01/01/1855
, etc.
Thanks @OammieR
for the initial idea.

goto cpanel and login as Main Admin or Super Administrator
find SSH/Shell Access ( you will find under the security tab of cpanel )
now give the username and password of Super Administrator as root
or whatyougave
note: do not give any username, cos, it needs permissions
once your into console type
type ' mysql
' and press enter now you find youself in
mysql>
/* and type here like */
mysql> set global net_buffer_length=1000000;
Query OK, 0 rows affected (0.00 sec)
mysql> set global max_allowed_packet=1000000000;
Query OK, 0 rows affected (0.00 sec)
Now upload and enjoy!!!
This should work and protect your form from being submitted if the number of files is greater then max_file_number.
$(function() {
var // Define maximum number of files.
max_file_number = 3,
// Define your form id or class or just tag.
$form = $('form'),
// Define your upload field class or id or tag.
$file_upload = $('#image_upload', $form),
// Define your submit class or id or tag.
$button = $('.submit', $form);
// Disable submit button on page ready.
$button.prop('disabled', 'disabled');
$file_upload.on('change', function () {
var number_of_images = $(this)[0].files.length;
if (number_of_images > max_file_number) {
alert(`You can upload maximum ${max_file_number} files.`);
$(this).val('');
$button.prop('disabled', 'disabled');
} else {
$button.prop('disabled', false);
}
});
});
You can keep note of below possibilities:
null
.However with multiple null
keys and values it will only take a null key value pair once.
Map<String, String> codes = new HashMap<String, String>();
codes.put(null, null);
codes.put(null,null);
codes.put("C1", "Acathan");
for(String key:codes.keySet()){
System.out.println(key);
System.out.println(codes.get(key));
}
output will be :
null //key of the 1st entry
null //value of 1st entry
C1
Acathan
null
only onceoptions.put(null, null);
Person person = sample.searchPerson(null);
It depends on the implementation of your searchPerson
method
if you want multiple values to be null
, you can implement accordingly
Map<String, String> codes = new HashMap<String, String>();
codes.put(null, null);
codes.put("X1",null);
codes.put("C1", "Acathan");
codes.put("S1",null);
for(String key:codes.keySet()){
System.out.println(key);
System.out.println(codes.get(key));
}
output:
null
null
X1
null
S1
null
C1
Acathan
Is there any method in Java or any open source library for escaping (not quoting) a special character (meta-character), in order to use it as a regular expression?
If you are looking for a way to create constants that you can use in your regex patterns, then just prepending them with "\\"
should work but there is no nice Pattern.escape('.')
function to help with this.
So if you are trying to match "\\d"
(the string \d
instead of a decimal character) then you would do:
// this will match on \d as opposed to a decimal character
String matchBackslashD = "\\\\d";
// as opposed to
String matchDecimalDigit = "\\d";
The 4 slashes in the Java string turn into 2 slashes in the regex pattern. 2 backslashes in a regex pattern matches the backslash itself. Prepending any special character with backslash turns it into a normal character instead of a special one.
matchPeriod = "\\.";
matchPlus = "\\+";
matchParens = "\\(\\)";
...
In your post you use the Pattern.quote(string)
method. This method wraps your pattern between "\\Q"
and "\\E"
so you can match a string even if it happens to have a special regex character in it (+
, .
, \\d
, etc.)
try using discount.toFixed(2);
You can call QCoreApplication::exit(0) to exit with code 0
The probably only way which is marginally faster than
d = [[] for x in xrange(n)]
is
from itertools import repeat
d = [[] for i in repeat(None, n)]
It does not have to create a new int
object in every iteration and is about 15 % faster on my machine.
Edit: Using NumPy, you can avoid the Python loop using
d = numpy.empty((n, 0)).tolist()
but this is actually 2.5 times slower than the list comprehension.
//Example to define how to do :
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("FirstName");
dt.Columns.Add("LastName");
dt.Columns.Add("Address");
dt.Columns.Add("City");
// The table structure is:
//ID FirstName LastName Address City
//Now we want to add a PhoneNo column after the LastName column. For this we use the
//SetOrdinal function, as iin:
dt.Columns.Add("PhoneNo").SetOrdinal(3);
//3 is the position number and positions start from 0.`enter code here`
//Now the table structure will be:
// ID FirstName LastName PhoneNo Address City
VistaDB has an express version which is free to use and is syntax and driver compatible with SQL Server. VistaDB is a single file and only requires their driver .dll to work in your asp.net or winforms project.
Since it is syntax and datasource compatible you can upgrade to SQL Server if needed.
from their site:
VistaDB is a fully managed and typesafe ASP.NET and WinForms applications using C#, VB.NET and other CLR-compliant languages.
Again if you don't want to use bodyParser, the following works:
var express = require('express');
var http = require('http');
var app = express();
app.use(express.static('./public'));
app.configure(function(){
app.use(express.methodOverride());
app.use(express.multipart({
uploadDir: './uploads',
keepExtensions: true
}));
});
app.use(app.router);
app.get('/upload', function(req, res){
// Render page with upload form
res.render('upload');
});
app.post('/upload', function(req, res){
// Returns json of uploaded file
res.json(req.files);
});
http.createServer(app).listen(3000, function() {
console.log('App started');
});
First of all, let's differentiate between GET
and POST
Get: It is the default HTTP
request that is made to the server and is used to retrieve the data from the server and query string that comes after ?
in a URI
is used to retrieve a unique resource.
this is the format
GET /someweb.asp?data=value HTTP/1.0
here data=value
is the query string value passed.
POST: It is used to send data to the server safely so anything that is needed, this is the format of a POST
request
POST /somweb.aspHTTP/1.0
Host: localhost
Content-Type: application/x-www-form-urlencoded //you can put any format here
Content-Length: 11 //it depends
Name= somename
Why POST over GET?
In GET
the value being sent to the servers are usually appended to the base URL in the query string,now there are 2 consequences of this
GET
requests are saved in browser history with the parameters. So your passwords remain un-encrypted in browser history. This was a real issue for Facebook back in the days.URI
can be. If have too many parameters being sent you might receive 414 Error - URI too long
In case of post request your data from the fields are added to the body instead. Length of request params is calculated, and added to the header for content-length and no important data is directly appended to the URL.
You can use the Google Developer Tools' network section to see basic information about how requests are made to the servers.
and you can always add more values in your Request Headers
like Cache-Control
, Origin
, Accept
.
Since there is discussion about performance I figured I'd add in a comparison that included StringBuilder. It is in fact faster than the concat and, naturally the String.format option.
To make this a sort of apples to apples comparison I instantiate a new StringBuilder in the loop rather than outside (this is actually faster than doing just one instantiation most likely due to the overhead of re-allocating space for the looping append at the end of one builder).
String formatString = "Hi %s; Hi to you %s";
long start = System.currentTimeMillis();
for (int i = 0; i < 1000000; i++) {
String s = String.format(formatString, i, +i * 2);
}
long end = System.currentTimeMillis();
log.info("Format = " + ((end - start)) + " millisecond");
start = System.currentTimeMillis();
for (int i = 0; i < 1000000; i++) {
String s = "Hi " + i + "; Hi to you " + i * 2;
}
end = System.currentTimeMillis();
log.info("Concatenation = " + ((end - start)) + " millisecond");
start = System.currentTimeMillis();
for (int i = 0; i < 1000000; i++) {
StringBuilder bldString = new StringBuilder("Hi ");
bldString.append(i).append("; Hi to you ").append(i * 2);
}
end = System.currentTimeMillis();
log.info("String Builder = " + ((end - start)) + " millisecond");
You can do this with a data URL. This includes the entire document in a single string of HTML. For example, the following HTML:
<html><body>foo</body></html>
can be encoded as this:
data:text/html;charset=utf-8,%3Chtml%3E%3Cbody%3Efoo%3C/body%3E%3C/html%3E
and then set as the src
attribute of the iframe. Example.
Edit: The other alternative is to do this with Javascript. This is almost certainly the technique I'd choose. You can't guarantee how long a data URL the browser will accept. The Javascript technique would look something like this:
var iframe = document.getElementById('foo'),
iframedoc = iframe.contentDocument || iframe.contentWindow.document;
iframedoc.body.innerHTML = 'Hello world';
Edit 2 (December 2017): use the Html5's srcdoc attribute, just like in Saurabh Chandra Patel's answer, who now should be the accepted answer! If you can detect IE/Edge efficiently, a tip is to use srcdoc-polyfill library only for them and the "pure" srcdoc attribute in all non-IE/Edge browsers (check caniuse.com to be sure).
<iframe srcdoc="<html><body>Hello, <b>world</b>.</body></html>"></iframe>
If you look inside Math.abs you can probably find the best answer:
Eg, for floats:
/*
* Returns the absolute value of a {@code float} value.
* If the argument is not negative, the argument is returned.
* If the argument is negative, the negation of the argument is returned.
* Special cases:
* <ul><li>If the argument is positive zero or negative zero, the
* result is positive zero.
* <li>If the argument is infinite, the result is positive infinity.
* <li>If the argument is NaN, the result is NaN.</ul>
* In other words, the result is the same as the value of the expression:
* <p>{@code Float.intBitsToFloat(0x7fffffff & Float.floatToIntBits(a))}
*
* @param a the argument whose absolute value is to be determined
* @return the absolute value of the argument.
*/
public static float abs(float a) {
return (a <= 0.0F) ? 0.0F - a : a;
}
This link has solution of how to get it working. Removing "pom.xml" from the "Profiles:" line and then click "Run".
Below is a batch file that will run corflags.exe
against all dlls
and exes
in the current working directory and all sub-directories, parse the results and display the target architecture of each.
Depending on the version of corflags.exe
that is used, the line items in the output will either include 32BIT
, or 32BITREQ
(and 32BITPREF
). Whichever of these two is included in the output is the critical line item that must be checked to differentiate between Any CPU
and x86
. If you are using an older version of corflags.exe
(pre Windows SDK v8.0A), then only the 32BIT
line item will be present in the output, as others have indicated in past answers. Otherwise 32BITREQ
and 32BITPREF
replace it.
This assumes corflags.exe
is in the %PATH%
. The simplest way to ensure this is to use a Developer Command Prompt
. Alternatively you could copy it from it's default location.
If the batch file below is run against an unmanaged dll
or exe
, it will incorrectly display it as x86
, since the actual output from Corflags.exe
will be an error message similar to:
corflags : error CF008 : The specified file does not have a valid managed header
@echo off
echo.
echo Target architecture for all exes and dlls:
echo.
REM For each exe and dll in this directory and all subdirectories...
for %%a in (.exe, .dll) do forfiles /s /m *%%a /c "cmd /c echo @relpath" > testfiles.txt
for /f %%b in (testfiles.txt) do (
REM Dump corflags results to a text file
corflags /nologo %%b > corflagsdeets.txt
REM Parse the corflags results to look for key markers
findstr /C:"PE32+">nul .\corflagsdeets.txt && (
REM `PE32+` indicates x64
echo %%~b = x64
) || (
REM pre-v8 Windows SDK listed only "32BIT" line item,
REM newer versions list "32BITREQ" and "32BITPREF" line items
findstr /C:"32BITREQ : 0">nul /C:"32BIT : 0" .\corflagsdeets.txt && (
REM `PE32` and NOT 32bit required indicates Any CPU
echo %%~b = Any CPU
) || (
REM `PE32` and 32bit required indicates x86
echo %%~b = x86
)
)
del corflagsdeets.txt
)
del testfiles.txt
echo.
I'm using version 2(supports both bootstrap v2 and v3) and for me this works:
$("#datepicker").datepicker( {
format: "mm/yyyy",
startView: "year",
minView: "year"
});
If the array element is not integer you can use something like below :
$skus = array('LDRES10','LDRES12','LDRES11'); //sample data
if(!empty($skus)){
$sql = "SELECT * FROM `products` WHERE `prodCode` IN ('" . implode("','", $skus) . "') "
}
z
means (un)z_ip.x
means ex_tract files from the archive.v
means print the filenames v_erbosely.f
means the following argument is a f_ilename.For more details, see tar
's man page.
You could just split the frontend and backend. The frontend is hosted on the customers server with an API that makes calls to the backend on your server. This keeps all of the proprietary code proprietary and forces users to sign up / pay for subscriptions.
As many already noticed, the problem manifests itself only if the extra string contains whitespaces.
The root cause is that OP's host OS/shell (i.e. Windows/cmd.exe) mangles the entered command - the "
characters get lost, --es sms_body "test from adb"
becomes --es sms_body test from adb
. Which results in sms_body
string extra getting assigned the value of test
and the rest of the string becoming <URI>|<PACKAGE>|<COMPONENT>
specifier.
To avoid all that you could use:
adb shell "am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body 'test from adb' -n com.whereismywifeserver/.IntentReceiver"
or just start the interactive adb shell
session first and run the am broadcast
command from inside of it.
add JAVA_HOME to the file:
/etc/environment
for it to be available to the entire system (you would need to restart Ubuntu though)
I know the answer is in reply to a question asked 6 years ago ...
But I was looking for something similar for a few hours and then found out that: cut -c does exactly that, with an added bonus that you could also specify an offset.
cut -c 1-5 will return Hello and cut -c 7-11 will return world. No need for any other command
You want to create an Object, not an Array.
Like so,
var Map = {};
Map['key1'] = 'value1';
Map['key2'] = 'value2';
You can check if the key exists in multiple ways:
Map.hasOwnProperty(key);
Map[key] != undefined // For illustration // Edit, remove null check
if (key in Map) ...
this is your first Activity1.
public class Activity1 extends Activity{
private int mRequestCode = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(this, Activity2.class);
startActivityForResult(intent, mRequestCode);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == mRequestCode && resultCode == RESULT_OK){
String editTextString = data.getStringExtra("editText");
}
}
}
From here you are starting your Activity2.class by using startActivityForResult(mRequestCode, Activity2.class);
Now this is your second Activity, name is Activity2
public class Activity2 extends Activity {
private EditText mEditText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//mEditText = (EditText)findViewById(R.id.edit_text);
Intent intent = new Intent();
intent.putExtra("editText", mEditText.getText().toString());
setResult(RESULT_OK, intent);
}
}
Now when you done with your second Activity then you call setResult() method, from onBackPress() or from any button click when your Activity2 will destroy then your Activity1's call back method onActivityResult() will call from there you can get your data from intent..
Hope it will help to you...:)
The standard way is to use audio/mpeg
which is something like this in your PHP header function ...
header('Content-Type: audio/mpeg');
You can also use AWK which can give you more flexibility to handle the file
awk '{ print "chmod 755 "$0"" | "/bin/sh"}' file.txt
if your file has a field separator like:
field1,field2,field3
To get only the first field you do
awk -F, '{ print "chmod 755 "$1"" | "/bin/sh"}' file.txt
You can check more details on GNU Documentation https://www.gnu.org/software/gawk/manual/html_node/Very-Simple.html#Very-Simple
I don't know why others haven't pointed out that this question is duplicated with this one with accepted answer.
I quote here the solution: You need to override the ControlTemplate
of the Button
:
<Button Content="save" Name="btnSaveEditedText"
Background="Transparent"
Foreground="White"
FontFamily="Tw Cen MT Condensed"
FontSize="30"
Margin="-280,0,0,10"
Width="60"
BorderBrush="Transparent"
BorderThickness="0">
<Button.Template>
<ControlTemplate TargetType="Button">
<ContentPresenter Content="{TemplateBinding Content}"/>
</ControlTemplate>
</Button.Template>
</Button>
You could use PhoneGap.
This has the benefit of being a cross-platform solution. Be warned though that you may need to pay subscription fees. The simplest solution is to just embed a WebView
as detailed in @Enigma's answer.
I think it actually depends on what are you going to do inside your doSomething
function. If you are going to access MyObject
properties using this keyword then you have to use that. But I think that the following code fragment will also work if you are not doing any special things using object(MyObject)
properties.
function doSomething(){
.........
}
$("#foobar").ready('click', function(){
});

If you don't want to deal with the WordPress API, then Adam's answer is really the best one.
If you were willing to deal with the API I would suggest hooking into the "template-redirect" hook, which would allow you to point a particular URL or page to an arbitrary PHP file while still having access to WordPress.
No, if you are debugging an app without other users use the Build > Build APK(s) menu in Android Studio or execute it in your device/emulator them the debug release apk will install automatically. If you are debugging an app with others use Build > Generate Signed APK... menu. If you want to publish the beta version use the Google Play Store. Your APK(s) will be in app\build\outputs\apk\debug
and app\release
folders.
This post is a little bit old, but here is another easy solution for getting data related to Call
logs content provider in Android:
Use this lib: https://github.com/EverythingMe/easy-content-providers
Get all calls:
CallsProvider callsProvider = new CallsProvider(context);
List<Call> calls = callsProvider.getCalls().getList();
Each Call has all fields, so you can get any info you need:
callDate, duration, number, type(INCOMING, OUTGOING, MISSED), isRead, ...
It works with List
or Cursor
and there is a sample app to see how it looks and works.
In fact, there is a support for all Android content providers like: Contacts, SMS, Calendar, ... Full doc with all options: https://github.com/EverythingMe/easy-content-providers/wiki/Android-providers
Hope it also helped :)
I know it is an old request. But it might still be useful to some. With current versions of MacPorts, you can choose the default gcc version using the port command. To list the available versions of gcc, use:
$ sudo port select --list gcc
Available versions for gcc: gcc42 llvm-gcc42 mp-gcc46 none (active)
To set gcc to the MacPorts version:
$ sudo port select --set gcc mp-gcc46
Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.

I was facing the same issue in my Angular application. I was using RocketChat REST API in my application and I was trying to use the rooms.createDiscussion
, but as an error as below.
ERROR Error: Uncaught (in promise): HttpErrorResponse: {"headers":{"normalizedNames":{},"lazyUpdate":null},"status":200,"statusText":"OK","url":"myurl/rocketchat/api/v1/rooms.createDiscussion","ok":false,"name":"HttpErrorResponse","message":"Http failure during parsing for myrul/rocketchat/api/v1/rooms.createDiscussion","error":{"error":{},"text":"
I have tried couple of things like changing the responseType: 'text'
but none of them worked. At the end I was able to find the issue was with my RocketChat installation. As mentioned in the RocketChat change log the API rooms.createDiscussion
is been introduced in the version 1.0.0 unfortunately I was using a lower version.
My suggestion is to check the REST API is working fine or not before you spend time to fix the error in your Angular code. I used curl
command to check that.
curl -H "X-Auth-Token: token" -H "X-User-Id: userid" -H "Content-Type: application/json" myurl/rocketchat/api/v1/rooms.createDiscussion -d '{ "prid": "GENERAL", "t_name": "Discussion Name"}'
There as well I was getting an invalid HTML as a response.
<!DOCTYPE html>
<html>
<head>
<meta name="referrer" content="origin-when-crossorigin">
<script>/* eslint-disable */
'use strict';
(function() {
var debounce = function debounce(func, wait, immediate) {
Instead of a valid JSON response as follows.
{
"discussion": {
"rid": "cgk88DHLHexwMaFWh",
"name": "WJNEAM7W45wRYitHo",
"fname": "Discussion Name",
"t": "p",
"msgs": 0,
"usersCount": 0,
"u": {
"_id": "rocketchat.internal.admin.test",
"username": "rocketchat.internal.admin.test"
},
"topic": "general",
"prid": "GENERAL",
"ts": "2019-04-03T01:35:32.271Z",
"ro": false,
"sysMes": true,
"default": false,
"_updatedAt": "2019-04-03T01:35:32.280Z",
"_id": "cgk88DHLHexwMaFWh"
},
"success": true
}
So after updating to the latest RocketChat I was able to use the mentioned REST API.
I need a fast function that can check if a file is exist or not and PherricOxide's answer is almost what I need except it does not compare the performance of boost::filesystem::exists and open functions. From the benchmark results we can easily see that :
Using stat function is the fastest way to check if a file is exist. Note that my results are consistent with that of PherricOxide's answer.
The performance of boost::filesystem::exists function is very close to that of stat function and it is also portable. I would recommend this solution if boost libraries is accessible from your code.

Here is the snippet of getting the attribute value of "lang" with XPath and VTD-XML.
import com.ximpleware.*;
public class getAttrVal {
public static void main(String s[]) throws VTDException{
VTDGen vg = new VTDGen();
if (!vg.parseFile("input.xml", false)){
return ;
}
VTDNav vn = vg.getNav();
AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/bookstore/book/title/@lang");
System.out.println(" lang's value is ===>"+ap.evalXPathToString());
}
}
The solution is to add your variable to /etc/profile
. Then everything works as expected!
Of course you MUST do it as a root user with sudo nano /etc/profile. If you edit it with any other way the system will complain with a damaged /etc/profile, even if you change the permissions to root.
Say we have two date select fields, field1, and field2. field2 date depends on field1
$('#field2').datepicker();
$('#field1').datepicker({
onSelect: function(dateText, inst) {
$('#field2').val("");
$('#field2').datepicker("option", "minDate", new Date(dateText));
}
});
HashMap has no concept of position so there is no way to get an object by position. Objects in Maps are set and get by keys.
The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!
If you want to hide them anyway: error_reporting(0);
SELECT 'INSERT SomeOtherDB.dbo.table(column1,column2,etc.)
SELECT ' + CONVERT(VARCHAR(12), Pk_Id) + ','
+ '''' + REPLACE(ProductName, '''', '''''') + ''','
+ CONVERT(VARCHAR(12), Fk_CompanyId) + ','
+ CONVERT(VARCHAR(12), Price) + ';'
FROM dbo.unspecified_table_name
WHERE Fk_CompanyId = 1;
You need to clear your Maven repository to solve this issue.
You can do this:
if (node is CasusNodeDTO)
{
...
}
else if (node is BucketNodeDTO)
{
...
}
...
While that would be more elegant, it's possibly not as efficient as some of the other answers here.
All will get executed and On first Called first run basis!!
<div id="target"></div>
<script>
$(document).ready(function(){
jQuery('#target').append('target edit 1<br>');
});
$(document).ready(function(){
jQuery('#target').append('target edit 2<br>');
});
$(document).ready(function(){
jQuery('#target').append('target edit 3<br>');
});
</script>
Demo As you can see they do not replace each other
Also one thing i would like to mention
in place of this
$(document).ready(function(){});
you can use this shortcut
jQuery(function(){
//dom ready codes
});
Beware of an undo-tree quirk for redo!
Many popular “starter kits” (prelude, purcell, spacemacs) come bundled with undo-tree. Most (all?) even auto-enable it. As mentioned, undo-tree is a handy way to visualize and traverse the undo/redo tree. Prelude even gives it a key-chord (uu
), and also C-x u
.
The problem is: undo-tree seems to wreck Emacs’ default and well-known binding for redo: C-g C-/
.
Instead, you can use these symmetrical keys for undo/redo:
C-/ undo
C-S-/ redo
These are useful since sometimes you want to quickly redo without opening up the visualizer.
Use the latest fs-extra
.
I had that problem on Ubuntu
(16 and 18) with plenty of file/socket-descriptors space (count with lsof |wc -l
). Used fs-extra
version 8.1.0
. After the update to 9.0.0
the "Error: EMFILE, too many open files" vanished.
I've experienced diverse problems on diverse OS' with node handling filesystems. Filesystems are obviously not trivial.
public void showHideFragment(final Fragment fragment){
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(android.R.animator.fade_in,
android.R.animator.fade_out);
if (fragment.isHidden()) {
ft.show(fragment);
Log.d("hidden","Show");
} else {
ft.hide(fragment);
Log.d("Shown","Hide");
}
ft.commit();
}
This will list Everything (including sub directories) from the directory you specify, in order, and with the attributes. I have spent days looking for something to do this, and I took parts from this entire discussion, and a little of my own, and put it together. ENJOY!!

The docker logs
command will show you the output a container is generating when you don't run it interactively. This is likely to include the error message.
docker logs --tail 50 --follow --timestamps mediawiki_web_1
You can also run a fresh container in the foreground with docker run -ti <your_wiki_image>
to see what that does. You may need to map some config from your docker-compose
yml to the docker
command.
I would guess that attaching to the media wiki process caused a crash which has corrupted something in your data.
Top answers are saying mathlog10 faster but I got results that suggest len(str(n)) is faster.
arr = []
for i in range(5000000):
arr.append(random.randint(0,12345678901234567890))
%%timeit
for n in arr:
len(str(n))
//2.72 s ± 304 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
%%timeit
for n in arr:
int(math.log10(n))+1
//3.13 s ± 545 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
Besides, I haven't added logic to the math way to return accurate results and I can only imagine it slows it even more.
I have no idea how the previous answers proved the maths way is faster though.
Use this in your server.js file
app.use(express.static('public'));
_x000D_
without the directory ( __dirname ) and then within your project folder create a new file and name it public then put all your static files inside it
I put a getchar()

NP stands for Non-deterministic Polynomial time.
This means that the problem can be solved in Polynomial time using a Non-deterministic Turing machine (like a regular Turing machine but also including a non-deterministic "choice" function). Basically, a solution has to be testable in poly time. If that's the case, and a known NP problem can be solved using the given problem with modified input (an NP problem can be reduced to the given problem) then the problem is NP complete.
The main thing to take away from an NP-complete problem is that it cannot be solved in polynomial time in any known way. NP-Hard/NP-Complete is a way of showing that certain classes of problems are not solvable in realistic time.
Edit: As others have noted, there are often approximate solutions for NP-Complete problems. In this case, the approximate solution usually gives an approximation bound using special notation which tells us how close the approximation is.
In my case I solved the problem by establishing a valid column number when applying the order
property inside the script where you configure the data table.
var table = $('#mytable').DataTable({
.
.
.
order: [[ 1, "desc" ]],
Maybe this will help you:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
I was facing same issue not able to post form without ajax. but found solution , hope it can help and someones time.
<form name="paymentitrform" id="paymentitrform" class="payment"
method="post"
action="abc.php">
<input name="email" value="" placeholder="email" />
<input type="hidden" name="planamount" id="planamount" value="0">
<input type="submit" onclick="form_submit() " value="Continue Payment" class="action"
name="planform">
</form>
You can submit post form, from bootstrap modal using below javascript/jquery code : call the below function onclick of input submit button
function form_submit() {
document.getElementById("paymentitrform").submit();
}
For me, the issue was some plugin in my Visual Studio started forcing my application into x64 64bit mode, so the Oracle driver wasn't being found as I had Oracle 32bit installed.
So if you are having this issue, try running Visual Studio in safemode (devenv /safemode). I could find that it was looking in SYSWOW64 for the ic.dll file by using the ProcMon app by SysInternals/Microsoft.
Update: For me it was the Telerik JustTrace product that was causing the issue, it was probably hooking in and affecting the runtime version somehow to do tracing.
Update2: It's not just JustTrace causing an issue, JustMock is causing the same processor mode issue. JustMock is easier to fix though: Click JustMock-> Disable Profiler and then my web app's oracle driver runs in the correct CPU mode. This might be fixed by Telerik in the future.
Install file loader first:
$ npm install file-loader --save-dev
And add this rule in webpack.config.js
{
test: /\.(png|jpg|gif)$/,
use: [{
loader: 'file-loader',
options: {}
}]
}
categories_posts
and categories_news
start with substring 'categories_' then it is enough to check that developer_configurations_cms.cfg_name_unique
starts with 'categories' instead of check if it contains the given substring. Translating all that into a query:
SELECT *
FROM developer_configurations_cms
WHERE developer_configurations_cms.cat_id = '1'
AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
AND developer_configurations_cms.cfg_name_unique NOT LIKE 'categories%'
I use ruamel.yaml. Details & debate here.
from ruamel import yaml
with open(filename, 'r') as fp:
read_data = yaml.load(fp)
Usage of ruamel.yaml is compatible (with some simple solvable problems) with old usages of PyYAML and as it is stated in link I provided, use
from ruamel import yaml
instead of
import yaml
and it will fix most of your problems.
EDIT: PyYAML is not dead as it turns out, it's just maintained in a different place.
