Just show file name extension from Windows Explorer, after applying the below steps, create a new file, and type your extension as .json
Open Folder Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Appearance and Personalization, and then clicking Folder Options.
Click the View tab, and then, under Advanced settings, clear the Hide extensions for known file types check box, and then click OK
var input= $(this);
input.innerHTML = '';
Java is not call by reference it is call by value only
But all variables of object type are actually pointers.
So if you use a Mutable Object you will see the behavior you want
public class XYZ {
public static void main(String[] arg) {
StringBuilder toyNumber = new StringBuilder("5");
play(toyNumber);
System.out.println("Toy number in main " + toyNumber);
}
private static void play(StringBuilder toyNumber) {
System.out.println("Toy number in play " + toyNumber);
toyNumber.append(" + 1");
System.out.println("Toy number in play after increement " + toyNumber);
}
}
Output of this code:
run:
Toy number in play 5
Toy number in play after increement 5 + 1
Toy number in main 5 + 1
BUILD SUCCESSFUL (total time: 0 seconds)
You can see this behavior in Standard libraries too. For example Collections.sort(); Collections.shuffle(); These methods does not return a new list but modifies it's argument object.
List<Integer> mutableList = new ArrayList<Integer>();
mutableList.add(1);
mutableList.add(2);
mutableList.add(3);
mutableList.add(4);
mutableList.add(5);
System.out.println(mutableList);
Collections.shuffle(mutableList);
System.out.println(mutableList);
Collections.sort(mutableList);
System.out.println(mutableList);
Output of this code:
run:
[1, 2, 3, 4, 5]
[3, 4, 1, 5, 2]
[1, 2, 3, 4, 5]
BUILD SUCCESSFUL (total time: 0 seconds)
As what, I guess pixparker wanted to say, but remained to be not clear enough, for me at least, do ensure that... All "Other Projects" have an "Output Type" of "Class Library" selected while... Only "One Project" being selected as either "Window Application" or "Console Application" output.
Perhaps a 63.2% / 36.8% is a reasonable choice. The reason would be that if you had a total sample size n and wanted to randomly sample with replacement (a.k.a. re-sample, as in the statistical bootstrap) n cases out of the initial n, the probability of an individual case being selected in the re-sample would be approximately 0.632, provided that n is not too small, as explained here: https://stats.stackexchange.com/a/88993/16263
For a sample of n=250, the probability of an individual case being selected for a re-sample to 4 digits is 0.6329. For a sample of n=20000, the probability is 0.6321.
Another reason for similar error message is trying to mock a final
method. One shouldn't attempt to mock final methods (see Final method mocking).
I have also confronted the error in a multi-threaded test. Answer by gna worked in that case.
If you need more Flexibility for the configurations, try the Settings4jPlaceholderConfigurer: http://settings4j.sourceforge.net/currentrelease/configSpringPlaceholder.html
In our application we use:
The default order which key-value-Source is checked first, is described in:
http://settings4j.sourceforge.net/currentrelease/configDefault.html
It can be customized with a settings4j.xml (accurate to log4j.xml) in your classpath.

select 1 from table
will return the constant 1 for every row of the table. It's useful when you want to cheaply determine if record matches your where
clause and/or join
.
You can send data through JSON or via normal POST, here is an example for JSON.
var value1 = 1;
var value2 = 2;
var value3 = 3;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "yoururlhere",
data: { data1: value1, data2: value2, data3: value3 },
success: function (result) {
// do something here
}
});
If you want to use it via normal post try this
$.ajax({
type: "POST",
url: $('form').attr("action"),
data: $('#form0').serialize(),
success: function (result) {
// do something here
}
});
Now that more time has passed, here's a way to do it in Java 8:
URLConnection conn = url.openConnection();
try (BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), StandardCharsets.UTF_8))) {
pageText = reader.lines().collect(Collectors.joining("\n"));
}
By default, Tomcat container doesn’t contain any jstl library. To fix it, declares jstl.jar in your Maven pom.xml file if you are working in Maven project or add it to your application's classpath
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
Generally using stored procedures is better for perfomances. For example in previous versions of SQL Server if you put the function in JOIN condition the cardinality estimate is 1 (before SQL 2012) and 100 (after SQL 2012 and before of SQL 2017) and the engine can generate a bad execution plan.
Also if you put it in WHERE clause the SQL Engine can generate a bad execution plan.
With SQL 2017 Microsoft introduced the feature called interleaved execution in order to produce a more accurate estimate but the stored procedure remains the best solution.
For more details look the following article of Joe Sack https://techcommunity.microsoft.com/t5/sql-server/introducing-interleaved-execution-for-multi-statement-table/ba-p/385417
html, body{
width:100%;
}
This tells the html to be 100% wide. But 100% refers to the whole browser window width, so no more than that.
You may want to set a min width instead.
html, body{
min-width:100%;
}
So it will be 100% as a minimum, bot more if needed.
man zshall and search for PROMPT EXPANSION
After reading the existing answers here, several of them are conflicting. I've tried the various approaches on systems running zsh 4.2 and 5+ and found that the reason these answers are conflicting is that they do not say which version of ZSH they are targeted at. Different versions use different syntax for this and some of them require various autoloads.
So, the best bet is probably to man zshall and search for PROMPT EXPANSION to find out all the rules for your particular installation of zsh. Note in the comments, things like "I use Ubuntu 11.04 or 10.4 or OSX" Are not very meaningful as it's unclear which version of ZSH you are using. Ubuntu 11.04 does not imply a newer version of ZSH than ubuntu 10.04. There may be any number of reasons that an older version was installed. For that matter a newer version of ZSH does not imply which syntax to use without knowing which version of ZSH it is.
Have you tried height: auto;
on your .container
div?
Here is a fiddle, if you change img height, container height will adjust to it.
EDIT
So if you "can't" change the inline min-height
, you can overwrite the inline style with an !important
parameter. It's not the cleanest way, but it solves your problem.
add to your .container
class this line
min-height:0px !important;
I've updated my fiddle to give you an example.
You can change the labels' text by adorning the property with the DisplayName
attribute.
[DisplayName("Someking Status")]
public string SomekingStatus { get; set; }
Or, you could write the raw HTML explicitly:
<label for="SomekingStatus" class="control-label">Someking Status</label>
The version I'm using I think is the good one, since is the exact same as the Android Developer Docs, except for the name of the string, they used "view" and I used "webview", for the rest is the same
No, it is not.
The one that is new to the N Developer Preview has this method signature:
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
The one that is supported by all Android versions, including N, has this method signature:
public boolean shouldOverrideUrlLoading(WebView view, String url)
So why should I do to make it work on all versions?
Override the deprecated one, the one that takes a String
as the second parameter.
GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
boardRepo.deleteByBoardId(id);
Faced the same issue. GOT javax.persistence.TransactionRequiredException: No EntityManager with actual transaction available for current thread
I resolved it by adding @Transactional annotation above the controller/service.
xd() {
printf "hex> "
while read i
do
printf "dec $(( 0x${i} ))\n\nhex> "
done
}
dx() {
printf "dec> "
while read i
do
printf 'hex %x\n\ndec> ' $i
done
}
You should use single-quotes for string delimiters. The single-quote is the standard SQL string delimiter, and double-quotes are identifier delimiters (so you can use special words or characters in the names of tables or columns).
In MySQL, double-quotes work (nonstandardly) as a string delimiter by default (unless you set ANSI
SQL mode). If you ever use another brand of SQL database, you'll benefit from getting into the habit of using quotes standardly.
Another handy benefit of using single-quotes is that the literal double-quote characters within your string don't need to be escaped:
select * from tablename where fields like '%string "hi" %';
I could resolve it by overriding Configuration in MyContext through adding connection string to the DbContextOptionsBuilder:
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
if (!optionsBuilder.IsConfigured)
{
IConfigurationRoot configuration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json")
.Build();
var connectionString = configuration.GetConnectionString("DbCoreConnectionString");
optionsBuilder.UseSqlServer(connectionString);
}
}
Update: As @Soham Shetty comments, getSegmentsAtEvent(event)
only works for 1.x and for 2.x getElementsAtEvent
should be used.
.getElementsAtEvent(e)
Looks for the element under the event point, then returns all elements at the same data index. This is used internally for 'label' mode highlighting.
Calling
getElementsAtEvent(event)
on your Chart instance passing an argument of an event, or jQuery event, will return the point elements that are at that the same position of that event.canvas.onclick = function(evt){ var activePoints = myLineChart.getElementsAtEvent(evt); // => activePoints is an array of points on the canvas that are at the same position as the click event. };
Example: https://jsfiddle.net/u1szh96g/208/
Original answer (valid for Chart.js 1.x version):
You can achieve this using getSegmentsAtEvent(event)
Calling
getSegmentsAtEvent(event)
on your Chart instance passing an argument of an event, or jQuery event, will return the segment elements that are at that the same position of that event.
From: Prototype Methods
So you can do:
$("#myChart").click(
function(evt){
var activePoints = myNewChart.getSegmentsAtEvent(evt);
/* do something */
}
);
Here is a full working example:
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.2.js"></script>
<script type="text/javascript" src="Chart.js"></script>
<script type="text/javascript">
var data = [
{
value: 300,
color:"#F7464A",
highlight: "#FF5A5E",
label: "Red"
},
{
value: 50,
color: "#46BFBD",
highlight: "#5AD3D1",
label: "Green"
},
{
value: 100,
color: "#FDB45C",
highlight: "#FFC870",
label: "Yellow"
}
];
$(document).ready(
function () {
var ctx = document.getElementById("myChart").getContext("2d");
var myNewChart = new Chart(ctx).Pie(data);
$("#myChart").click(
function(evt){
var activePoints = myNewChart.getSegmentsAtEvent(evt);
var url = "http://example.com/?label=" + activePoints[0].label + "&value=" + activePoints[0].value;
alert(url);
}
);
}
);
</script>
</head>
<body>
<canvas id="myChart" width="400" height="400"></canvas>

Robocopy replaces XCopy in the newer versions of windows
Yes i agree with Mark Setchell, They are both crap. (brought to you by Microsoft)
UPDATE:
XCopy return codes:
0 - Files were copied without error.
1 - No files were found to copy.
2 - The user pressed CTRL+C to terminate xcopy. enough memory or disk space, or you entered an invalid drive name or invalid syntax on the command line.
5 - Disk write error occurred.
Robocopy returns codes:
0 - No errors occurred, and no copying was done. The source and destination directory trees are completely synchronized.
1 - One or more files were copied successfully (that is, new files have arrived).
2 - Some Extra files or directories were detected. No files were copied Examine the output log for details.
3 - (2+1) Some files were copied. Additional files were present. No failure was encountered.
4 - Some Mismatched files or directories were detected. Examine the output log. Some housekeeping may be needed.
5 - (4+1) Some files were copied. Some files were mismatched. No failure was encountered.
6 - (4+2) Additional files and mismatched files exist. No files were copied and no failures were encountered. This means that the files already exist in the destination directory
7 - (4+1+2) Files were copied, a file mismatch was present, and additional files were present.
8 - Some files or directories could not be copied (copy errors occurred and the retry limit was exceeded). Check these errors further.
16 - Serious error. Robocopy did not copy any files. Either a usage error or an error due to insufficient access privileges on the source or destination directories.
There is more details on Robocopy return values here: http://ss64.com/nt/robocopy-exit.html
Yes - you can create encapsulated property, but it's not been done with access modifiers (public|private) at least not with ES6.
Here is a simple example how it can be done with ES6:
1 Create class using class word
2 Inside it's constructor declare block-scoped variable using let OR const reserved words -> since they are block-scope they cannot be accessed from outside (encapsulated)
3 To allow some access control (setters|getters) to those variables you can declare instance method inside it's constructor using: this.methodName=function(){}
syntax
"use strict";
class Something{
constructor(){
//private property
let property="test";
//private final (immutable) property
const property2="test2";
//public getter
this.getProperty2=function(){
return property2;
}
//public getter
this.getProperty=function(){
return property;
}
//public setter
this.setProperty=function(prop){
property=prop;
}
}
}
Now lets check it:
var s=new Something();
console.log(typeof s.property);//undefined
s.setProperty("another");//set to encapsulated `property`
console.log(s.getProperty());//get encapsulated `property` value
console.log(s.getProperty2());//get encapsulated immutable `property2` value
hdfs dfs -count <dir>
info from man page:
-count [-q] [-h] [-v] [-t [<storage type>]] [-u] <path> ... :
Count the number of directories, files and bytes under the paths
that match the specified file pattern. The output columns are:
DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME
or, with the -q option:
QUOTA REM_QUOTA SPACE_QUOTA REM_SPACE_QUOTA
DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME
Restarting the computer was the only thing that worked for me. Classic 101 IT :)
To access the tomcat manager from different machine you have to follow bellow steps:
1. Update conf/tomcat-users.xml file with user and some roles:
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>
Here admin user is assigning roles="manager-gui,manager-script,manager-jmx,manager-status".
Here tomcat user and password is : admin
2. Update webapps/manager/META-INF/context.xml file (Allowing IP address):
Default configuration:
<Context antiResourceLocking="false" privileged="true" >
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
<Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
Here in Valve it is allowing only local machine IP start with 127.\d+.\d+.\d+ .
2.a : Allow specefic IP:
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|YOUR.IP.ADDRESS.HERE" />
Here you just replace |YOUR.IP.ADDRESS.HERE with your IP address
2.b : Allow all IP:
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow=".*" />
Here using allow=".*" you are allowing all IP.
Thanks :)
I have routine in VB ..
but you should have 2 pictureboxes .. 1 for frame .. 1 for the image .. and it make keep the picture's size ratio
Assumed picFrame is the image frame and picImg is the image
Sub InsertPicture(ByVal oImg As Image)
Dim oFoto As Image
Dim x, y As Integer
oFoto = oImg
picImg.Visible = False
picImg.Width = picFrame.Width - 2
picImg.Height = picFrame.Height - 2
picImg.Location = New Point(1, 1)
SetPicture(picPreview, oFoto)
x = (picImg.Width - picFrame.Width) / 2
y = (picImg.Height - picFrame.Height) / 2
picImg.Location = New Point(x, y)
picImg.Visible = True
End Sub
I'm sure you can make it as C# ....
require 'date'
current_time = DateTime.now
current_time.strftime "%d/%m/%Y %H:%M"
# => "14/09/2011 17:02"
current_time.next_month.strftime "%d/%m/%Y %H:%M"
# => "14/10/2011 17:02"
These things helped me
Hope this helps someone out there.
I had the same issue today. The file I was trying to load into my code was open for editing in Excel. After closing Excel, the code began to work!
In my case I was reading the stream in a jersey RequestEventListener I created on the server side to log the request body prior to the request being processed. I then realized that this probably resulted in the subsequent read to yield no string (which is what is passed over when the business logic is run). I verified that to be the case.
So if you are using streams to read the JSON string be careful of that.
Within the dplyr world, try:
select(iris,contains("Sepal"))
See the Selection section in ?select
for numerous other helpers like starts_with
, ends_with
, etc.
There is a little hack with php. And it works not only with Google, but with any website you don't control and can't add Access-Control-Allow-Origin *
We need to create PHP-file (ex. getContentFromUrl.php) on our webserver and make a little trick.
PHP
<?php
$ext_url = $_POST['ext_url'];
echo file_get_contents($ext_url);
?>
JS
$.ajax({
method: 'POST',
url: 'getContentFromUrl.php', // link to your PHP file
data: {
// url where our server will send request which can't be done by AJAX
'ext_url': 'https://stackoverflow.com/questions/6114436/access-control-allow-origin-error-sending-a-jquery-post-to-google-apis'
},
success: function(data) {
// we can find any data on external url, cause we've got all page
var $h1 = $(data).find('h1').html();
$('h1').val($h1);
},
error:function() {
console.log('Error');
}
});
How it works:
And we can make events onClick, put this event on some button. Hope this will help!
I've really taken recently to display: table
to give things a fixed size such as to enable margin: 0 auto
to work. Has made my life a lot easier. You just need to get past the fact that 'table' display doesn't mean table html.
It's especially useful for responsive design where things just get hairy and crazy 50% left this and -50% that just become unmanageable.
style
{
display: table;
margin: 0 auto
}
In addition if you've got two buttons and you want them the same width you don't even need to know the size of each to get them to be the same width - because the table will magically collapse them for you.
(this also works if they're inline and you want to center two buttons side to side - try doing that with percentages!).
Use the LogCat and try to find what is causing the app to crash.
To see Logcat if you use Android Studio then Press ALT + 6 or
if you use Eclipse then Window -> Open Perspective -> Other - LogCat
Go to the LogCat, from the drop down menu select error. This will contain all the required information to help you debug. If that doesn't help, post the LogCat as an edit to your question and somebody will help you out.

This one works for me. You can see this code on AccountController -> Register
var user = new JobUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
//add this to add role to user
await UserManager.AddToRoleAsync(user.Id, "Name of your role");
}
but the role name must exist in your AspNetRoles table.

Actually, thinking about it, you don't need a magic square, just a count for each row/column/diagonal. This is a little easier than generalizing a magic square to n
× n
matrices, since you just need to count to n
.
Yes use NOT NULL
in your query like this below.
SELECT *
FROM table
WHERE col IS NOT NULL;
run following command to run container
docker run --name db_name -e MYSQL_ROOT_PASSWORD=PASS--publish 8306:3306 db_name
run this command to get mysql db in host machine
mysql -h 127.0.0.1 -P 8306 -uroot -pPASS
in your case it is
mysql -h 127.0.0.1 -P 12345 -uroot -pPASS
Whats wrong in this?

I find many answers up to date and properly answered but will add something new to stack of answers.
In python there are infinite ways to do this,
here are some instances
Normal way
>>> l= [1,2,"stackoverflow","python"]
>>> l
[1, 2, 'stackoverflow', 'python']
>>> tup = tuple(l)
>>> type(tup)
<type 'tuple'>
>>> tup
(1, 2, 'stackoverflow', 'python')
smart way
>>>tuple(item for item in l)
(1, 2, 'stackoverflow', 'python')
Remember tuple is immutable ,used for storing something valuable. For example password,key or hashes are stored in tuples or dictionaries. If knife is needed why to use sword to cut apples. Use it wisely, it will also make your program efficient.
Hide the triple quotes in a context that won't be mistaken for a docstring, eg:
'''
...statements...
''' and None
or:
if False: '''
...statements...
'''
git push
or
git push server_name master
should do the trick, after you have made a commit to your local repository.
I combined the best of all the simple answers, without hard-coded domains.
301 permanent redirect from non-www to www (HTTP or HTTPS):
server {
if ($host !~ ^www\.) {
rewrite ^ $scheme://www.$host$request_uri permanent;
}
# Regular location configs...
}
If you prefer non-HTTPS, non-www to HTTPS, www redirect at the same time:
server {
listen 80;
if ($host !~ ^www\.) {
rewrite ^ https://www.$host$request_uri permanent;
}
rewrite ^ https://$host$request_uri permanent;
}
I'm not cool enough for comments. I fixed the plunker from the accepted answer to work for rc2. Nothing fancy, links to the CDN were just broken is all.

I ran into this problem because I had multiple wildcard entries for the same ports. You can easily check this by executing apache2ctl -S
:
# apache2ctl -S
[Wed Oct 22 18:02:18 2014] [warn] _default_ VirtualHost overlap on port 30000, the first has precedence
[Wed Oct 22 18:02:18 2014] [warn] _default_ VirtualHost overlap on port 20001, the first has precedence
VirtualHost configuration:
11.22.33.44:80 is a NameVirtualHost
default server xxx.com (/etc/apache2/sites-enabled/xxx.com.conf:1)
port 80 namevhost xxx.com (/etc/apache2/sites-enabled/xxx.com.conf:1)
[...]
11.22.33.44:443 is a NameVirtualHost
default server yyy.com (/etc/apache2/sites-enabled/yyy.com.conf:37)
port 443 namevhost yyy.com (/etc/apache2/sites-enabled/yyy.com.conf:37)
wildcard NameVirtualHosts and _default_ servers:
*:80 hostname.com (/etc/apache2/sites-enabled/000-default:1)
*:20001 hostname.com (/etc/apache2/sites-enabled/000-default:33)
*:30000 hostname.com (/etc/apache2/sites-enabled/000-default:57)
_default_:443 hostname.com (/etc/apache2/sites-enabled/default-ssl:2)
*:20001 hostname.com (/etc/apache2/sites-enabled/default-ssl:163)
*:30000 hostname.com (/etc/apache2/sites-enabled/default-ssl:178)
Syntax OK
Notice how at the beginning of the output are a couple of warning lines. These will indicate which ports are creating the problems (however you probably already knew that).
Next, look at the end of the output and you can see exactly which files and lines the virtualhosts are defined that are creating the problem. In the above example, port 20001 is assigned both in /etc/apache2/sites-enabled/000-default
on line 33 and /etc/apache2/sites-enabled/default-ssl
on line 163. Likewise *:30000
is listed in 2 places. The solution (in my case) was simply to delete one of the entries.
If you would use data.table
package for the operations on data.frame then the problem is not present.
library(data.table)
dt = data.table(col1 = c("a","b","c"), col2 = 1:3)
sapply(dt, class)
# col1 col2
#"character" "integer"
If you have a factor columns in you dataset already and you want to convert them to character you can do the following.
library(data.table)
dt = data.table(col1 = factor(c("a","b","c")), col2 = 1:3)
sapply(dt, class)
# col1 col2
# "factor" "integer"
upd.cols = sapply(dt, is.factor)
dt[, names(dt)[upd.cols] := lapply(.SD, as.character), .SDcols = upd.cols]
sapply(dt, class)
# col1 col2
#"character" "integer"
that's all you need
childView.frame = parentView.bounds

See if this example helps: http://bootply.com/mQh8DyRfWY
The brand is centered using..
.navbar-brand
{
position: absolute;
width: 100%;
left: 0;
top: 0;
text-align: center;
margin: auto;
}
Your markup is for Bootstrap 2, not 3. There is no longer a navbar-inner
.
EDIT - Another approach is using transform: translateX(-50%);
.navbar-brand {
transform: translateX(-50%);
left: 50%;
position: absolute;
}
http://www.bootply.com/V7vKDfk46G
In Bootstrap 4, mx-auto
or flexbox can be used to center the brand and other elements. See How to position navbar contents in Bootstrap 4 for an explanation.

I originally saw this error after upgrading from 0.2.13 to 0.3. These instructions have been updated for the release of Android Studio 0.5.2. These are the steps I completed to resolve the issue.
1.In build.gradle make sure gradle is set to 0.9.0
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.9.0'
}
}
2.In gradle-wrapper.properties make sure to use gradle 1.11
#Wed Apr 10 15:27:10 PDT 2013
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=http\://services.gradle.org/distributions/gradle-1.11-all.zip
3.Sync project with gradle files by pressing the button to the left of the avd button
4.Try to build project again. If still having issues possibly try File > Invalidate Caches/Restart
NOTE: If you are using 0.9.+
and it gives Could not GET 'http://repo1.maven.org/maven2/com/android/tools/build/gradle/'. Received status code 401 from server: Unauthorized
(happens sporadically) then change to 0.9.0
. Also, you have to use build tools 19.0 or greater I believe so make sure you have those downloaded in sdk manager and use as buildToolsVersion
in whichever gradle file holds that info.
def _assertNotRaises(self, exception, obj, attr):
try:

could be modified if you need to accept parameters.
call like

You can't resize an image without losing some quality, simply because you are reducing the number of pixels.
Don't reduce the size client side, because browsers don't do a good job of resizing images.
What you can do is programatically change the size before you render it, or as a user uploads it.
Here is an article that explains one way to do this in c#: http://www.codeproject.com/KB/GDI-plus/imageresize.aspx
There is a workaround by capturing clicks on document.body
and then checking event target.
document.body.addEventListener( 'click', function ( event ) {
if( event.srcElement.id == 'btnSubmit' ) {
someFunc();
};
} );
The deepmerge npm package appears to be the most widely used library for solving this problem: https://www.npmjs.com/package/deepmerge
For the example case above, it is usually omitted, yes. However, either way is syntactically correct.
You can insert the formula =HYPERLINK(<your_cell>,<your_cell>)
to the adjacent cell and drag it along all the way to the bottom. This will give you a column with all the links. Now, you can select your original column by clicking on the header, right-click, and select Hide
.
The problem is how 100% height is being calculated. Two ways to deal with this.
Add 20px to the body padding-bottom
body {
padding-bottom: 20px;
}
or add a transparent border to body
body {
border: 1px solid transparent;
}
Both worked for me in firebug
Below are some comments regarding the correctness of my answer to this question. These kinds of discussions are exactly why stackoverflow is so great. Many different people have different opinions on how best to solve the problem. I've learned some incredible coding style that I would not have thought of myself. And I've been told that readers have learned something from my style from time to time. Social coding has really encouraged me to be a better programmer.
Social coding can, at times, be disturbing. I hate it when I spend 30 minutes flushing out an answer with a jsfiddle and detailed explanation only to submit and find 10 other answers all saying the same thing in less detail. And the author accepts someone else's answer. How frustrating! I think that this has happend to my fellow contributors–in particular thirtydot.
Thirtydot's answer is completely legit. The p
around the script
is the culprit in this problem. Remove it and the space goes away. It also is a good answer to this question.
But why? Shouldn't the p
tag's height, padding and margin be calculated into the height of the body?
And it is! If you remove the padding-bottom style that I've suggested and then set the body's background to black, you will see that the body's height includes this extra p
space accurately (you see the strip at the bottom turn to black). But the gradient fails to include it when finding where to start. This is the real problem.
The two solutions that I've offered are ways to tell the browser to calculate the gradient properly. In fact, the padding-bottom could just be 1px. The value isn't important, but the setting is. It makes the browser take a look at where the body ends. Setting the border will have the same effect.
In my opinion, a padding setting of 20px looks the best for this page and that is why I answered it this way. It is addressing the problem of where the gradient starts.
Now, if I were building this page. I would have avoided wrapping the script in a p tag. But I must assume that author of the page either can't change it or has a good reason for putting it in there. I don't know what that script does. Will it write something that needs a p tag? Again, I would avoid this practice and it is fine to question its presence, but also I accept that there are cases where it must be there.
My hope in writing this "defense" is that the people who marked down this answer might consider that decision. My answer is thought out, purposeful, and relevant. The author thought so. However, in this social environment, I respect that you disagree and have a right to degrade my answer. I just hope that your choice is motivated by disagreement with my answer and not that author chose mine over yours.
You need to use the TO_DATE
function.
SELECT TO_DATE('01/01/2004', 'MM/DD/YYYY') FROM DUAL;
This is the solution for people that do care about accessibility.
Please, don't use outline:none;
for disabling the focus outline. You are killing accessibility of the web if you do this. There is a accessible way of doing this.
Check out this article that I've written to explain how to remove the border in an accessible way.
The idea in short is to only show the outline border when we detect a keyboard user. Once a user starts using his mouse we disable the outline. As a result you get the best of the two.
The easiest way is to use the create
Manager method, which creates and saves the object in a single step.
for item in items:
MyModel.objects.create(name=item.name)
Step 1, create your table:
CREATE TABLE epictable
(
mytable_key serial primary key,
moobars VARCHAR(40) not null,
foobars DATE
);
Step 2, insert values into your table like this, notice that mytable_key is not specified in the first parameter list, this causes the default sequence to autoincrement.
insert into epictable(moobars,foobars) values('delicious moobars','2012-05-01')
insert into epictable(moobars,foobars) values('worldwide interblag','2012-05-02')
Step 3, select * from your table:
el@voyager$ psql -U pgadmin -d kurz_prod -c "select * from epictable"
Step 4, interpret the output:
mytable_key | moobars | foobars
-------------+-----------------------+------------
1 | delicious moobars | 2012-05-01
2 | world wide interblags | 2012-05-02
(2 rows)
Observe that mytable_key column has been auto incremented.
ProTip:
You should always be using a primary key on your table because postgresql internally uses hash table structures to increase the speed of inserts, deletes, updates and selects. If a primary key column (which is forced unique and non-null) is available, it can be depended on to provide a unique seed for the hash function. If no primary key column is available, the hash function becomes inefficient as it selects some other set of columns as a key.
According to the standard (§6.4.4.4/10)
The value of an integer character constant containing more than one character (e.g., 'ab'), [...] is implementation-defined.
long x = '\xde\xad\xbe\xef'; // yes, single quotes
This is valid ISO 9899:2011 C. It compiles without warning under gcc
with -Wall
, and a “multi-character character constant” warning with -pedantic
.
From Wikipedia:
Multi-character constants (e.g. 'xy') are valid, although rarely useful — they let one store several characters in an integer (e.g. 4 ASCII characters can fit in a 32-bit integer, 8 in a 64-bit one). Since the order in which the characters are packed into one int is not specified, portable use of multi-character constants is difficult.
For portability sake, don't use multi-character constants with integral types.
Add this line under the dependencies in your gradle file
compile 'com.android.support:support-annotations:27.1.1'
No. Neither Visual Studio or the .NET framework will run on Mac OSX (although the latter is changing). However, if you want to write an application in a similar framework, you could use Mono and MonoDevelop.
It fires. Check demo http://jsfiddle.net/yeyene/kbAk3/
$("#inline_content input[name='type']").click(function(){
alert('You clicked radio!');
if($('input:radio[name=type]:checked').val() == "walk_in"){
alert($('input:radio[name=type]:checked').val());
//$('#select-table > .roomNumber').attr('enabled',false);
}
});
Add "-static" to other linker options solves this problem. I was just having the same issue after I tested this on another system, but not on my own, so even if you haven't noticed this on your development system, you should check that you have this set if you're statically linking.
Another note, copying the DLL into the same folder as the executable is not a solution as it defeats the idea of statically linking.
Another option is to use the TDM version of MinGW which solves this problem.
Update edit: this may not solve the problem for everyone. Another reason I recently discovered for this is when you use a library compiled by someone else, in my case it was SFML which was improperly compiled and so required a DLL that did not exist as it was compiled with a different version of MinGW than what I use. I use a dwarf build, this used another one, so I didn't have the DLL anywhere and of course, I didn't want it as it was a static build. The solution may be to find another build of the library, or build it yourself.
Note that the TIMEDIFF()
solution only works when the datetimes
are less than 35 days apart!
TIMEDIFF()
returns a TIME
datatype, and the max value for TIME is 838:59:59 hours (=34,96 days)
For me, this problem went away on Windows when I moved my project to a shallower parent directory, i.e. to:
C:\Users\spenc\Desktop\MyProjectDirectory
instead of
C:\Users\spenc\Desktop\...\MyProjectDirectory
.
I think the source of the problem was that MSBuild has a file path length restriction to 260 characters. This causes the basic compiler test CMake performs to build a project called CompilerIdCXX.vcxproj
to fail with the error:
C1083: Cannot open source file: 'CMakeCXXCompilerId.cpp'
because the length of the file's path e.g.
C:\Users\spenc\Desktop\...\MyProjectDirectory\build\CMakeFiles\...\CMakeCXXCompilerId.cpp
exceeds the MAX_PATH restriction.
CMake then concludes there is no CXX compiler.

I'd like to offer another simple comparison between python and JS example, if this helps make things clearer.
JS:
function make () {
var cl = 1;
function gett () {
console.log(cl);
}
function sett (val) {
cl = val;
}
return [gett, sett]
}
and executing:
a = make(); g = a[0]; s = a[1];
s(2); g(); // 2
s(3); g(); // 3
Python:
def make ():
cl = 1
def gett ():
print(cl);
def sett (val):
cl = val
return gett, sett
and executing:
g, s = make()
g() #1
s(2); g() #1
s(3); g() #1
Reason: As many others said above, in python, if there is an assignment in the inner scope to a variable with the same name, a new reference in the inner scope is created. Not so with JS, unless you explicitly declare one with the var
keyword.
This is now supported (as of 2019). Please see sajad saderi's answer below for instructions.
No, this is not currently supported (in 2015).
I had a similar problem. I was working on a project where I did not control the web.xml configuration file, so I could not use the changes suggested about altering the version. Of course the project was not using JSF so this was especially annoying for me.
I found that there is a really simple fix. Go to Preferences > Maven > Java EE Itegration and uncheck the "JSF Configurator" box.
I did this in a fresh workspace before importing the project again, but it may work equally as well on an existing project ... not sure.
This is one way to do it:
Fiddle here: http://jsfiddle.net/4Mvan/1/
HTML:
<div class='container'>
<a href='#'>
<img class='resize_fit_center'
src='http://i.imgur.com/H9lpVkZ.jpg' />
</a>
</div>
CSS:
.container {
margin: 10px;
width: 115px;
height: 115px;
line-height: 115px;
text-align: center;
border: 1px solid red;
}
.resize_fit_center {
max-width:100%;
max-height:100%;
vertical-align: middle;
}
If you are building with Eclipse, make sure your project's build target is set to Honeycomb too.
Try with this:
$.ajax({

url: URL,
defaultHeaders: {
'Content-Type': 'application/json',
"Access-Control-Allow-Origin": "*",
'Accept': 'application/json'
},
data: obj,
dataType: 'json',
success: function (response) {
// BindTableData();
console.log("success ");
alert(response);
},
error: function (xhr) {
console.log("error ");
console.log(xhr);
}
});
A bit verbose, but it's the standard way of parsing and formatting dates in Java:
DateFormat formatter = new SimpleDateFormat("HH:mm:ss");
try {
Date dt = formatter.parse("08:19:12");
Calendar cal = Calendar.getInstance();
cal.setTime(dt);
int hour = cal.get(Calendar.HOUR);
int minute = cal.get(Calendar.MINUTE);
int second = cal.get(Calendar.SECOND);
} catch (ParseException e) {
// This can happen if you are trying to parse an invalid date, e.g., 25:19:12.
// Here, you should log the error and decide what to do next
e.printStackTrace();
}
Downside of all answers here is that they use static field names, so I wrote an adjusted version in OOP style. Assumed you are using getter methods you could directly use this Class and use the field name as parameter. Probably someone find it useful.
class CustomSort{
public $field = '';
public function cmp($a, $b)
{
/**
* field for order is in a class variable $field
* using getter function with naming convention getVariable() we set first letter to uppercase
* we use variable variable names - $a->{'varName'} would directly access a field
*/
return strcmp($a->{'get'.ucfirst($this->field)}(), $b->{'get'.ucfirst($this->field)}());
}
public function sortObjectArrayByField($array, $field)
{
$this->field = $field;
usort($array, array("Your\Namespace\CustomSort", "cmp"));;
return $array;
}
}

You will want to look into the nl2br() function along with the trim().
The nl2br()
will insert <br />
before the newline character (\n
) and the trim()
will remove any ending \n
or whitespace characters.
$text = trim($_POST['textareaname']); // remove the last \n or whitespace character
$text = nl2br($text); // insert <br /> before \n
That should do what you want.
UPDATE
The reason the following code will not work is because in order for \n
to be recognized, it needs to be inside double quotes since double quotes parse data inside of them, where as single quotes takes it literally, IE "\n"
$text = str_replace('\n', '<br />', $text);
To fix it, it would be:
$text = str_replace("\n", '<br />', $text);
But it is still better to use the builtin nl2br()
function, PHP provides.
EDIT
Sorry, I figured the first question was so you could add the linebreaks in, indeed this will change the answer quite a bit, as anytype of explode()
will remove the line breaks, but here it is:
$text = trim($_POST['textareaname']);
$textAr = explode("\n", $text);
$textAr = array_filter($textAr, 'trim'); // remove any extra \r characters left behind
foreach ($textAr as $line) {
// processing here.
}
If you do it this way, you will need to append the <br />
onto the end of the line before the processing is done on your own, as the explode()
function will remove the \n
characters.
Added the array_filter()
to trim()
off any extra \r
characters that may have been lingering.
In my case with Android 8.0(Oreo), no one of this solutions worked! If you have more than 1 user, then you should go to Settings->Applications->All Applications->Find the application and uninstall for all users! After this steps, it worked!
Use attribute fill-opacity
in your element of SVG.
Default value is 1, minimum is 0, in step use decimal values EX: 0.5 = 50% of alpha. Note: It is necessary to define fill
color to apply fill-opacity
.
See my example.
Switch is not a good way to go as it breaks the Open Close Principal. This is how I do it.
public class Animal
{
public abstract void Speak();
}
public class Dog : Animal
{
public virtual void Speak()
{
Console.WriteLine("Hao Hao");
}
}
public class Cat : Animal
{
public virtual void Speak()
{
Console.WriteLine("Meauuuu");
}
}
And here is how to use it (taking your code):
foreach (var animal in zoo)
{
echo animal.speak();
}
Basically what we are doing is delegating the responsibility to the child class instead of having the parent decide what to do with children.
You might also want to read up on "Liskov Substitution Principle".
You lookup the value of the data with findData()
and then use setCurrentIndex()
QComboBox* combo = new QComboBox;
combo->addItem("100",100.0); // 2nd parameter can be any Qt type
combo->addItem .....
float value=100.0;
int index = combo->findData(value);
if ( index != -1 ) { // -1 for not found
combo->setCurrentIndex(index);
}
Inspired by VB.Net Generics List(Of Integer), I created my own module for that. Maybe you find it useful, too or you'd like to extend for additional methods e.g. to remove items again:
'Save module with name: ListOfInteger
Public Function ListLength(list() As Integer) As Integer
On Error Resume Next
ListLength = UBound(list) + 1
On Error GoTo 0
End Function
Public Sub ListAdd(list() As Integer, newValue As Integer)
ReDim Preserve list(ListLength(list))
list(UBound(list)) = newValue
End Sub
Public Function ListContains(list() As Integer, value As Integer) As Boolean
ListContains = False
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
If list(MyCounter) = value Then
ListContains = True
Exit For
End If
Next
End Function
Public Sub DebugOutputList(list() As Integer)
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
Debug.Print list(MyCounter)
Next
End Sub
You might use it as follows in your code:
Public Sub IntegerListDemo_RowsOfAllSelectedCells()
Dim rows() As Integer
Set SelectedCellRange = Excel.Selection
For Each MyCell In SelectedCellRange
If IsEmpty(MyCell.value) = False Then
If ListOfInteger.ListContains(rows, MyCell.Row) = False Then
ListAdd rows, MyCell.Row
End If
End If
Next
ListOfInteger.DebugOutputList rows
End Sub
If you need another list type, just copy the module, save it at e.g. ListOfLong and replace all types Integer by Long. That's it :-)
public static Bitmap resizeAndCropCenter(Bitmap bitmap, int size, boolean recycle) {
int w = bitmap.getWidth();
int h = bitmap.getHeight();
if (w == size && h == size) return bitmap;
// scale the image so that the shorter side equals to the target;
// the longer side will be center-cropped.
float scale = (float) size / Math.min(w, h);
Bitmap target = Bitmap.createBitmap(size, size, getConfig(bitmap));
int width = Math.round(scale * bitmap.getWidth());
int height = Math.round(scale * bitmap.getHeight());
Canvas canvas = new Canvas(target);
canvas.translate((size - width) / 2f, (size - height) / 2f);
canvas.scale(scale, scale);
Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG | Paint.DITHER_FLAG);
canvas.drawBitmap(bitmap, 0, 0, paint);
if (recycle) bitmap.recycle();
return target;
}
private static Bitmap.Config getConfig(Bitmap bitmap) {
Bitmap.Config config = bitmap.getConfig();
if (config == null) {
config = Bitmap.Config.ARGB_8888;
}
return config;
}
To parse the search parameters from the URL, you need to annotate the controller method parameters with [FromQuery]
, for example:
[Route("api/person")]
public class PersonController : Controller
{
[HttpGet]
public string GetById([FromQuery]int id)
{
}
[HttpGet]
public string GetByName([FromQuery]string firstName, [FromQuery]string lastName)
{
}
[HttpGet]
public string GetByNameAndAddress([FromQuery]string firstName, [FromQuery]string lastName, [FromQuery]string address)
{
}
}
If you using the node-mysql module, just remove the .connect and .end. Just solved the problem myself. Apparently they pushed in unnecessary code in their last iteration that is also bugged. You don't need to connect if you have already ran the createConnection call
The difference between a shared project and a class library is that the latter is compiled and the unit of reuse is the assembly.
Whereas with the former, the unit of reuse is the source code, and the shared code is incorporated into each assembly that references the shared project.
This can be useful when you want to create separate assemblies that target specific platforms but still have code that should be shared.
See also here:
The shared project reference shows up under the References node in the Solution Explorer, but the code and assets in the shared project are treated as if they were files linked into the main project.
In previous versions of Visual Studio1, you could share source code between projects by Add -> Existing Item and then choosing to Link. But this was kind of clunky and each separate source file had to be selected individually. With the move to supporting multiple disparate platforms (iOS, Android, etc), they decided to make it easier to share source between projects by adding the concept of Shared Projects.
1 This question and my answer (up until now) suggest that Shared Projects was a new feature in Visual Studio 2015. In fact, they made their debut in Visual Studio 2013 Update 2
The following example shows commit parents as well:
git log --graph --all \
--format='%C(cyan dim) %p %Cred %h %C(white dim) %s %Cgreen(%cr)%C(cyan dim) <%an>%C(bold yellow)%d%Creset'
You're looking for implode()
$string = implode(",", $array);
To those who simply want to get the content (request body) from the request:
Use the [FromBody]
attribute in your controller method parameter.
[Route("api/mytest")]
[ApiController]
public class MyTestController : Controller
{
[HttpPost]
[Route("content")]
public async Task<string> ReceiveContent([FromBody] string content)
{
// Do work with content
}
}
As doc says: this attribute specifies that a parameter or property should be bound using the request body.
Working for me, I am using PHP 5.6. openssl extension should be enabled and while calling google map api verify_peer make false Below code is working for me.
<?php
$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
);
$url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="
. $latitude
. ","

$data = file_get_contents($url, false, stream_context_create($arrContextOptions));
echo $data;
?>
Is it possible to add onclick to a div and have it occur if any area of the div is clicked.
Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work
If yes then why is the onclick method not going through to my div.
You are assigning a string where a function is expected.
divTag.onclick = printWorking;
There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.
That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener
The function add() returns the old date, but changes the original date :)
startdate = "20.03.2014";
var new_date = moment(startdate, "DD.MM.YYYY");
new_date.add(5, 'days');
alert(new_date);
As mentioned, you can use:
=Format(Fields!Price.Value, "C")
A digit after the "C" will specify precision:
=Format(Fields!Price.Value, "C0")
=Format(Fields!Price.Value, "C1")
You can also use Excel-style masks like this:
=Format(Fields!Price.Value, "#,##0.00")
Haven't tested the last one, but there's the idea. Also works with dates:
=Format(Fields!Date.Value, "yyyy-MM-dd")
I can't say for sure if this is the case, but what appeared to be a problem for me was having .gitignore files in some of the subdirectories. Again, I can't guarantee this, but everything worked after these were deleted.
in addition to the options shown in your question, there is the possibility of implementing the action directly in your xml file from the menu, for example:
<item
android:id="@+id/OK_MENU_ITEM"
android:onClick="showMsgDirectMenuXml" />
And for your Java (Activity) file, you need to implement a public method with a single parameter of type MenuItem, for example:
private void showMsgDirectMenuXml(MenuItem item) {
Toast toast = Toast.makeText(this, "OK", Toast.LENGTH_LONG);
toast.show();
}
NOTE: This method will have behavior similar to the onOptionsItemSelected (MenuItem item)
There are several scenarios to consider. First of all, you need to check the type of your object. You can simply call GetType() for this. If the type does not implement IDynamicMetaObjectProvider, then you can use reflection same as for any other object. Something like:
var propertyInfo = test.GetType().GetProperties();
However, for IDynamicMetaObjectProvider implementations, the simple reflection doesn't work. Basically, you need to know more about this object. If it is ExpandoObject (which is one of the IDynamicMetaObjectProvider implementations), you can use the answer provided by itowlson. ExpandoObject stores its properties in a dictionary and you can simply cast your dynamic object to a dictionary.
If it's DynamicObject (another IDynamicMetaObjectProvider implementation), then you need to use whatever methods this DynamicObject exposes. DynamicObject isn't required to actually "store" its list of properties anywhere. For example, it might do something like this (I'm reusing an example from my blog post):
public class SampleObject : DynamicObject
{
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = binder.Name;
return true;
}
}
In this case, whenever you try to access a property (with any given name), the object simply returns the name of the property as a string.
dynamic obj = new SampleObject();
Console.WriteLine(obj.SampleProperty);
//Prints "SampleProperty".
So, you don't have anything to reflect over - this object doesn't have any properties, and at the same time all valid property names will work.
I'd say for IDynamicMetaObjectProvider implementations, you need to filter on known implementations where you can get a list of properties, such as ExpandoObject, and ignore (or throw an exception) for the rest.
All those answers are good, but I'd like to add a note on constructors with a little more complex initializations.
class SomeClass {
private int StringLength;
SomeClass(string x) {
// this is the logic that shall be executed for all constructors.
// you dont want to duplicate it.
StringLength = x.Length;
}
SomeClass(int a, int b): this(TransformToString(a, b)) {
}
private static string TransformToString(int a, int b) {
var c = a + b;
return $"{a} + {b} = {c}";
}
}
Allthogh this example might as well be solved without this static function, the static function allows for more complex logic, or even calling methods from somewhere else.
Use logging module (http://docs.python.org/library/logging.html):
import logging
logger = logging.getLogger('scope.name')
file_log_handler = logging.FileHandler('logfile.log')
logger.addHandler(file_log_handler)
stderr_log_handler = logging.StreamHandler()
logger.addHandler(stderr_log_handler)
# nice output format
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
file_log_handler.setFormatter(formatter)
stderr_log_handler.setFormatter(formatter)
logger.info('Info message')
logger.error('Error message')

developer not taking care of appending the h t t p : / / if it does not exist. Hope it saves somebody's time.
When you
import App from './App.jsx';
That means it will import whatever you export default
. You can rename App
class inside App.jsx
to whatever you want as long as you export default
it will work but you can only have one export default.
So you only need to export default App
and you don't need to export the rest.
If you still want to export the rest of the components, you will need named export.

I agree with the correct answer above, but.... your still not giving the index value for the data that you want to add to tempData. Without the [index] value the whole array will be added.
Try this:

Some suggestions:
<button>
data-
prefixed attributes for event data on the elementMarkup:
<div id="main_img">
<img id="img" src="1772031_29_b.jpg">
</div>
<ul id="thumb_img">
<li><button data-src='1772031_29_b.jpg'><img src='1772031_29_t.jpg' /></button></li>
<li><button data-src='1772031_55_b.jpg'><img src='1772031_55_t.jpg' /></button></li>
<li><button data-src='1772031_53_b.jpg'><img src='1772031_53_t.jpg' /></button></li>
</ul>
JavaScript:
If you need to support IE and other legacy browsers, Use a proper polyfill for Array.from
function clickedButton(btn, event) {
document.getElementById('img').src = btn.getAttribute('data-src');
}
function bindClick(btn) {
btn.addEventListener('click', clickedButton.bind(null,btn));
}
// Setup click handler(s) when content is loaded
document.addEventListener("DOMContentLoaded", function(){
Array.from(document.querySelectorAll('#thumb_img > button'))
.forEach(bindClick));
});
Edit: Vanilla JS for modern browsers.
__pycache__
is a folder containing Python 3 bytecode compiled and ready to be executed.
I don't recommend routinely deleting these files or suppressing creation during development as it may hurt performance. Just have a recursive command ready (see below) to clean up when needed as bytecode can become stale in edge cases (see comments).
Python programmers usually ignore bytecode. Indeed __pycache__
and *.pyc
are common lines to see in .gitignore
files. Bytecode is not meant for distribution and can be disassembled using dis
module.
If you are using OS X you can easily hide all of these folders in your project by running following command from the root folder of your project.
find . -name '__pycache__' -exec chflags hidden {} \;
Replace __pycache__
with *.pyc
for Python 2.
This sets a flag on all those directories (.pyc files) telling Finder/Textmate 2 to exclude them from listings. Importantly the bytecode is there, it's just hidden.
Rerun the command if you create new modules and wish to hide new bytecode or if you delete the hidden bytecode files.
On Windows the equivalent command might be (not tested, batch script welcome):
dir * /s/b | findstr __pycache__ | attrib +h +s +r
Which is same as going through the project hiding folders using right-click > hide...
Running unit tests is one scenario (more in comments) where deleting the *.pyc
files and __pycache__
folders is indeed useful. I use the following lines in my ~/.bash_profile
and just run cl
to clean up when needed.
alias cpy='find . -name "__pycache__" -delete'
alias cpc='find . -name "*.pyc" -delete'
...
alias cl='cpy && cpc && ...'
and more lately

I do not understand what you are asking. You ask "Should I use an IDE instead of...", but I don't understand what the alternative is - Vim and Emacs fulfil many functions any IDE will give you. The only aspect they do not handle that a larger IDE may are things like UI designers. Then your question boils down to simply "what IDE should I use" with arguments to be made for the simpler realm of Vim and Emacs.
If this didn't work:
<ImageView

android:paddingTop="10px"
android:paddingBottom="5px"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:src="@android:drawable/divider_horizontal_bright" />
Try this raw View:
<View

android:layout_height="1dip"
android:background="#000000" />
I've written a very simple extension method on DateTime
and DateTimeOffset
to do this. I wanted it to work exactly like a TotalMonths
property on TimeSpan
would work: i.e. return the count of complete months between two dates, ignoring any partial months. Because it's based on DateTime.AddMonths()
it respects different month lengths and returns what a human would understand as a period of months.
(Unfortunately you can't implement it as an extension method on TimeSpan because that doesn't retain knowledge of the actual dates used, and for months they're important.)
The code and tests are both available on GitHub. The code is very simple:
public static int GetTotalMonthsFrom(this DateTime dt1, DateTime dt2)
{
DateTime earlyDate = (dt1 > dt2) ? dt2.Date : dt1.Date;
DateTime lateDate = (dt1 > dt2) ? dt1.Date : dt2.Date;
// Start with 1 month's difference and keep incrementing
// until we overshoot the late date
int monthsDiff = 1;
while (earlyDate.AddMonths(monthsDiff) <= lateDate)
{
monthsDiff++;
}
return monthsDiff - 1;
}
And it passes all these unit test cases:
// Simple comparison
Assert.AreEqual(1, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 2, 1)));
// Just under 1 month's diff
Assert.AreEqual(0, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 1, 31)));
// Just over 1 month's diff
Assert.AreEqual(1, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 2, 2)));
// 31 Jan to 28 Feb
Assert.AreEqual(1, new DateTime(2014, 1, 31).GetTotalMonthsFrom(new DateTime(2014, 2, 28)));
// Leap year 29 Feb to 29 Mar
Assert.AreEqual(1, new DateTime(2012, 2, 29).GetTotalMonthsFrom(new DateTime(2012, 3, 29)));
// Whole year minus a day
Assert.AreEqual(11, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2012, 12, 31)));
// Whole year
Assert.AreEqual(12, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2013, 1, 1)));
// 29 Feb (leap) to 28 Feb (non-leap)
Assert.AreEqual(12, new DateTime(2012, 2, 29).GetTotalMonthsFrom(new DateTime(2013, 2, 28)));
// 100 years
Assert.AreEqual(1200, new DateTime(2000, 1, 1).GetTotalMonthsFrom(new DateTime(2100, 1, 1)));
// Same date
Assert.AreEqual(0, new DateTime(2014, 8, 5).GetTotalMonthsFrom(new DateTime(2014, 8, 5)));
// Past date
Assert.AreEqual(6, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2011, 6, 10)));

it's not a RESTful approach anymore, but you can now call your actions by name (rather than let the Web API automatically determine one for you based on the verb) like this:
[POST] /api/VTRouting/TSPRoute
[POST] /api/VTRouting/Route
Contrary to popular belief, there is nothing wrong with this approach, and it's not abusing Web API. You can still leverage on all the awesome features of Web API (delegating handlers, content negotiation, mediatypeformatters and so on) - you just ditch the RESTful approach.
This tree is not a binary tree, so you need an array of the children elements, like List.

One reason to use an explicite Platform.runLater() could be that you bound a property in the ui to a service (result) property. So if you update the bound service property, you have to do this via runLater():
In UI thread also known as the JavaFX Application thread:
...
listView.itemsProperty().bind(myListService.resultProperty());
...
in Service implementation (background worker):
...
Platform.runLater(() -> result.add("Element " + finalI));

Since TestRef is a class (which are reference objects), you can change the contents inside t without passing it as a ref. However, if you pass t as a ref, TestRef can change what the original t refers to. i.e. make it point to a different object.

Today March 6, 2013, Microsoft released SQL Server Data Tools – Business Intelligence for Visual Studio 2012 (SSDT BI) templates. With SSDT BI for Visual Studio 2012 you can develop and deploy SQL Server Business intelligence projects. Projects created in Visual Studio 2010 can be opened in Visual Studio 2012 and the other way around without upgrading or downgrading – it just works.
The download/install is named to ensure you get the SSDT templates that contain the Business Intelligence projects. The setup for these tools is now available from the web and can be downloaded in multiple languages right here: http://www.microsoft.com/download/details.aspx?id=36843

Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.
You can check this by running in Windows PowerShell:
> Get-Service ssh-agent
And then check the output of status is not running.
Status Name DisplayName
------ ---- -----------
Stopped ssh-agent OpenSSH Authentication Agent
Then check that the service has been disabled by running
> Get-Service ssh-agent | Select StartType
StartType
---------
Disabled
I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:
> Get-Service -Name ssh-agent | Set-Service -StartupType Manual
Alternatively, you can set it through the GUI if you prefer.

Client side data validation can be useful for a better user experience: for example, I a user who types wrongly his email address, should not wait til his request is processed by a remote server to learn about the typo he did.
Nevertheless, as an attacker can bypass client side validation (and may even not use the browser at all), server side validation is required, and must be the real gate to protect your backend from nefarious users.
The short answer is adb is used via command line. find adb.exe on your machine, add it to the path and use it from cmd on windows.
"adb devices" will give you a list of devices adb can talk to. your emulation platform should be on the list. just type adb to get a list of commands and what they do.
You should use Javascript animations for this - it is not possible in pure CSS, because you can't know the height of any element. Follow the instructions it has for you about javascript animation implementation, and copy slideUp and slideDown from jQuery's source.
I used the Visual Studio 2008 Uninstall tool and it worked fine for me.
You can use this tool to uninstall Visual Studio 2008 official release and Visual Studio 2008 Release candidate (Only English version).

Be sure you run the tool with admin-rights.
As @jwalkerjr mentioned, you should be disposing of connections in code (if connection pooling is enabled, they are just returned to the connection pool). The prescribed way to do this is using the 'using
' statement:
// Execute stored proc to read data from repository
using (SqlConnection conn = new SqlConnection(this.connectionString))
{
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "LoadFromRepository";
cmd.CommandType = CommandType.StoredProcedure;

I have just used dompdf and the code was a little different but it worked.
Here it is:
require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);
$html =
'<html><body>'.
'<p>Put your html here, or generate it with your favourite '.
'templating system.</p>'.
'</body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$output = $dompdf->output();
file_put_contents('Brochure.pdf', $output);
Only difference here is that all of the files in the include directory are included.
Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.
HTML:
<input id="id_ok" class="btn btn-space" value="OK" type="button">
<input id="id_cancel" class="btn btn-space" value="Cancel" type="button">
CSS:
.btn-space {
margin-right: 5px;
}
input[type='text'], input[type='password']
{
// my css
}
That is the correct way to do it. Sadly CSS is not a programming language.
ID VALUE1 VALUE2
===================

select ID, (coalesce(VALUE1 ,0) + coalesce(VALUE2 ,0) as Total from TableName
When I need this kind of functionality in Java, I usually use the Observer pattern. It does imply an extra object, but I think it's a clean way to go, and is a widely understood pattern, which helps with code readability.
According to Yashu's instructions, I wrote the following function (it's PL/SQL code, but it should be easily adaptable to any other language).
FUNCTION field(str IN VARCHAR2) RETURN VARCHAR2 IS
C_NEWLINE CONSTANT CHAR(1) := '
'; -- newline is intentional
v_aux VARCHAR2(32000);
v_has_double_quotes BOOLEAN;
v_has_comma BOOLEAN;
v_has_newline BOOLEAN;
BEGIN
v_has_double_quotes := instr(str, '"') > 0;
v_has_comma := instr(str,',') > 0;
v_has_newline := instr(str, C_NEWLINE) > 0;
IF v_has_double_quotes OR v_has_comma OR v_has_newline THEN
IF v_has_double_quotes THEN
v_aux := replace(str,'"','""');
ELSE
v_aux := str;
END IF;
return '"'||v_aux||'"';
ELSE
return str;
END IF;
END;
There's no need for nested looping (outer looping through tables and inner looping through all table columns). One can retrieve all (or arbitrary selected/filtered) table-column combinations from INFORMATION_SCHEMA.COLUMNS
and in one loop simply pass through (search) all of them:
DECLARE @search VARCHAR(100), @table SYSNAME, @column SYSNAME
DECLARE curTabCol CURSOR FOR
SELECT c.TABLE_SCHEMA + '.' + c.TABLE_NAME, c.COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS c
JOIN INFORMATION_SCHEMA.TABLES t
ON t.TABLE_NAME=c.TABLE_NAME AND t.TABLE_TYPE='BASE TABLE' -- avoid views
WHERE c.DATA_TYPE IN ('varchar','nvarchar') -- searching only in these column types
--AND c.COLUMN_NAME IN ('NAME','DESCRIPTION') -- searching only in these column names
SET @search='john'
OPEN curTabCol
FETCH NEXT FROM curTabCol INTO @table, @column
WHILE (@@FETCH_STATUS = 0)
BEGIN
EXECUTE('IF EXISTS
(SELECT * FROM ' + @table + ' WHERE ' + @column + ' = ''' + @search + ''')
PRINT ''' + @table + '.' + @column + '''')
FETCH NEXT FROM curTabCol INTO @table, @column
END
CLOSE curTabCol
DEALLOCATE curTabCol
Since API 16 you can supply an activity options bundle when calling Context.startActivity(Intent, Bundle) or related methods. It is created via the ActivityOptions builder:
Intent myIntent = new Intent(context, MyActivity.class);
ActivityOptions options =
ActivityOptions.makeCustomAnimation(context, R.anim.fade_in, R.anim.fade_out);
context.startActivity(myIntent, options.toBundle());
Don't forget to check out the other methods of the ActivityOptions builder and the ActivityOptionsCompat if you are using the Support Library.
API 5+:
For apps targeting API level 5+ there is the Activities overridePendingTransition
method. It takes two resource IDs for the incoming and outgoing animations. An id of 0
will disable the animations. Call this immediately after the startActivity
call.
i.e.:
startActivity(new Intent(this, MyActivity.class));
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
API 3+:
You can prevent the default animation (Slide in from the right) with the Intent.FLAG_ACTIVITY_NO_ANIMATION
flag in your intent.
i.e.:
Intent myIntent = new Intent(context, MyActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
context.startActivity(myIntent);
then in your Activity you simply have to specify your own animation.
This also works for the 1.5 API (Level 3).
In your oncreateView() method you need to write this code and in KEYCODE_BACk condition you can write whatever the functionality you want
View v = inflater.inflate(R.layout.xyz, container, false);
//Back pressed Logic for fragment
v.setFocusableInTouchMode(true);
v.requestFocus();
v.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
getActivity().finish();
Intent intent = new Intent(getActivity(), MainActivity.class);
startActivity(intent);
return true;
}
}
return false;
}
});
If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):
var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");
// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");
var hiddenField = document.createElement("input");
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);
// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');
form.submit();
function addAttr(scope, el, attrName, attrValue) {
el.replaceWith($compile(el.clone().attr(attrName, attrValue))(scope));
}
My mistake was forgetting to add the .ThenInclude(s => s.SubChildEntities) onto the parent .Include(c => c.SubChildEntities) to the Controller action when attempting to call the SubChildEntities in the Razor view.
var <parent> = await _context.Parent
.Include(c => c.<ChildEntities>)
.ThenInclude(s => s.<SubChildEntities>)
.SingleOrDefaultAsync(m => m.Id == id);
It should be noted that Visual Studio 2017 Community's IntelliSense doesn't pick up the SubChildEntities object in the lambda expression in the .ThenInclude(). It does successfully compile and execute though.
Using jQuery 1.9.1 I just found out that, although technically identical)*, this did not work in IE10 (but in Firefox):
// did not work in IE10
$(function() {
$(window).resize(CmsContent.adjustSize);
});
while this worked in both browsers:
// did work in IE10
$(function() {
$(window).bind('resize', function() {
CmsContent.adjustSize();
};
});
Edit:
)* Actually not technically identical, as noted and explained in the comments by WraithKenny and Henry Blyth.
You can handle the AppDomain.UnhandledException
event
EDIT: actually, this event is probably more adequate: Application.DispatcherUnhandledException
The selected answer doesn't always ensure that HTML is stripped, as it's still possible to construct an invalid HTML string through it by crafting a string like the following.
"<<h1>h1>foo<<//</h1>h1/>"
This input will ensure that the stripping assembles a set of tags for you and will result in:
"<h1>foo</h1>"
additionally jquery's text function will strip text not surrounded by tags.
Here's a function that uses jQuery but should be more robust against both of these cases:
var stripHTML = function(s) {
var lastString;
do {
s = $('<div>').html(lastString = s).text();
} while(lastString !== s)
return s;
};

On newer versions of yum, this information is stored in the "yumdb" when the package is installed. This is the only 100% accurate way to get the information, and you can use:
yumdb search from_repo repoid
(or repoquery and grep -- don't grep yum output). However the command "find-repos-of-install" was part of yum-utils for a while which did the best guess without that information:
http://james.fedorapeople.org/yum/commands/find-repos-of-install.py

SignTool is available as part of the Windows SDK (which comes with Visual Studio Community 2015). Make sure to select the "ClickOnce Publishing Tools" from the feature list during the installation of Visual Studio 2015 to get the SignTool.

I have been researching this for a few days, following endless leads that got close, but not quite, to what I was after.
My need is for a simple list of 'symbol, sector, industry'. I'm working in Java and don't want to use any platform native code.
It seems that most other data, like quotes, etc., is readily available.
Finally, followed a suggestion to look at 'finviz.com'. Looks like just the ticket. Try using the following:
http://finviz.com/export.ashx?v=111&t=aapl,cat&o=ticker This comes back as lines, csv style, with a header row, ordered by ticker symbol. You can keep adding tickers. In code, you can read the stream. Or you can let the browser ask you whether to open or save the file.
http://finviz.com/export.ashx?v=111&&o=ticker Same csv style, but pulls all available symbols (a lot, across global exchanges)
Replace 'export' with 'screener' and the data will show up in the browser.
There are many more options you can use, one for every screener element on the site.
So far, this is the most powerful and convenient programmatic way to get the few pieces of data I couldn't otherwise seem to easily get. And, it looks like this site could well be a single source for most of what you might need other than real- or near-real-time quotes.
This is my piece of Groovy code for that. Tested.
private static void copyLargeDir(File dirFrom, File dirTo){
// creation the target dir
if (!dirTo.exists()){
dirTo.mkdir();
}
// copying the daughter files
dirFrom.eachFile(FILES){File source ->
File target = new File(dirTo,source.getName());
target.bytes = source.bytes;
}
// copying the daughter dirs - recursion
dirFrom.eachFile(DIRECTORIES){File source ->
File target = new File(dirTo,source.getName());
copyLargeDir(source, target)
}
}
Xcode 10 Swift 4.2
To show Push Notification when your app is in the foreground -
Step 1 : add delegate UNUserNotificationCenterDelegate in AppDelegate class.
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
Step 2 : Set the UNUserNotificationCenter delegate
let notificationCenter = UNUserNotificationCenter.current()
notificationCenter.delegate = self
Step 3 : This step will allow your app to show Push Notification even when your app is in foreground
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound])
}
Step 4 : This step is optional. Check if your app is in the foreground and if it is in foreground then show Local PushNotification.
func application(_ application: UIApplication,didReceiveRemoteNotification userInfo: [AnyHashable: Any],fetchCompletionHandler completionHandler:@escaping (UIBackgroundFetchResult) -> Void) {
let state : UIApplicationState = application.applicationState
if (state == .inactive || state == .background) {
// go to screen relevant to Notification content
print("background")
} else {
// App is in UIApplicationStateActive (running in foreground)
print("foreground")
showLocalNotification()
}
}
Local Notification function -
fileprivate func showLocalNotification() {
//creating the notification content
let content = UNMutableNotificationContent()
//adding title, subtitle, body and badge
content.title = "App Update"
//content.subtitle = "local notification"
content.body = "New version of app update is available."
//content.badge = 1
content.sound = UNNotificationSound.default()
//getting the notification trigger
//it will be called after 5 seconds
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false)
//getting the notification request
let request = UNNotificationRequest(identifier: "SimplifiedIOSNotification", content: content, trigger: trigger)
//adding the notification to notification center
notificationCenter.add(request, withCompletionHandler: nil)
}
In bootstrap-3.3.7.js you will see the following code.
if (this.options.remote) {
this.$element
.find('.modal-content')
.load(this.options.remote, $.proxy(function () {
this.$element.trigger('loaded.bs.modal')
}, this))
}
So the bootstrap is going to replace the remote content into <div class="modal-content">
element. This is the default behavior by framework. So the problem is in your remote content itself, it should contain <div class="modal-header">
, <div class="modal-body">
, <div class="modal-footer">
by design.
If you'd like to see this feature added natively, along with all of the advanced functionality, I'd suggest upvoting the open GitHub issue here.
Following @dennmatt 's answer, I noticed that InternetAddress.lookup
may return successful results even if the internet connection is off - I tested it by connecting from my simulator to my home WiFi, and then disconnecting my router's cable. I think the reason is that the router caches the domain-lookup results so it does not have to query the DNS servers on each lookup request.
Anyways, if you use Firestore like me, you can replace the try-SocketException-catch block with an empty transaction and catch TimeoutExceptions:
try {
await Firestore.instance.runTransaction((Transaction tx) {}).timeout(Duration(seconds: 5));
hasConnection = true;
} on PlatformException catch(_) { // May be thrown on Airplane mode
hasConnection = false;
} on TimeoutException catch(_) {
hasConnection = false;
}
Also, please notice that previousConnection
is set before the async intenet-check, so theoretically if checkConnection()
is called multiple times in a short time, there could be multiple hasConnection=true
in a row or multiple hasConnection=false
in a row.
I'm not sure if @dennmatt did it on purpose or not, but in our use-case there were no side effects (setState
was only called twice with the same value).

Update 2018-07-23
As was just pointed out in the comments, this question was about getting a screenshot from the command line. Sorry, I just read over that. So here is the correct answer:
As of Firefox 57 you can create a screenshot in headless mode like this:
firefox -screenshot https://developer.mozilla.com
Read more in the documentation.
Update 2017-06-15
As of Firefox 55 there is Firefox Screenshots as a more flexible alternative. As of Firefox 57 Screenshots can capture a full page, too.
Original answer
Since Firefox 32 there is also a full page screenshot button in the developer tools (F12). If it is not enabled go to the developer tools settings (gear button) and choose "Take a fullpage screenshot" at the "Available Toolbox Buttons" section.
source: developer.mozilla.org
By default the screenshots are saved in the download directory. This works similar to screenshot --fullpage
in the toolbar.
What you need is named array. I wanted to write the following code:
int[] n = new int[4];
for(int i=1;i<4;i++)
{
n[i] = 5;
}
From Creating Pipes in C, this shows you how to fork a program to use a pipe. If you don't want to fork(), you can use named pipes.
In addition, you can get the effect of prog1 | prog2
by sending output of prog1
to stdout and reading from stdin
in prog2
. You can also read stdin by opening a file named /dev/stdin
(but not sure of the portability of that).

You can get the[hostname]\[instancename] by:
SELECT @@SERVERNAME;
To get only the hostname when you have hostname\instance name format:
SELECT LEFT(ltrim(rtrim(@@ServerName)), Charindex('\', ltrim(rtrim(@@ServerName))) -1)
Alternatively as @GilM pointed out:
SELECT SERVERPROPERTY('MachineName')
You can get the actual IP address using this:
create Procedure sp_get_ip_address (@ip varchar(40) out)
as
begin
Declare @ipLine varchar(200)
Declare @pos int
set nocount on
set @ip = NULL
Create table #temp (ipLine varchar(200))
Insert #temp exec master..xp_cmdshell 'ipconfig'
select @ipLine = ipLine
from #temp
where upper (ipLine) like '%IP ADDRESS%'
if (isnull (@ipLine,'***') != '***')
begin
set @pos = CharIndex (':',@ipLine,1);
set @ip = rtrim(ltrim(substring (@ipLine ,
@pos + 1 ,
len (@ipLine) - @pos)))
end
drop table #temp
set nocount off
end
go
declare @ip varchar(40)
exec sp_get_ip_address @ip out
print @ip

Hi for LandscapeLeft and LandscapeRight (Update Swift 2.0)
And you have this in info
And UIController
override func shouldAutorotate() -> Bool {
return true
}
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
return [UIInterfaceOrientationMask.LandscapeLeft,UIInterfaceOrientationMask.LandscapeRight]
}
For PortraitUpsideDown and Portrait use that
override func shouldAutorotate() -> Bool {
if (UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeLeft ||
UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeRight ||
UIDevice.currentDevice().orientation == UIDeviceOrientation.Unknown) {
return false
}
else {
return true
}
}
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
return [UIInterfaceOrientationMask.Portrait ,UIInterfaceOrientationMask.PortraitUpsideDown]
}
Message from France, Merry Christmas !
Edit :
Other solution :
extension UINavigationController {
public override func shouldAutorotate() -> Bool {
if visibleViewController is MyViewController {
return true // rotation
} else {
return false // no rotation
}
}
public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
return (visibleViewController?.supportedInterfaceOrientations())!

You can use android:stopWithTask="false"
in manifest as bellow, This means even if user kills app by removing it from tasklist, your service won't stop.
<service android:name=".service.StickyService"
android:stopWithTask="false"/>
In short, to do modification on the list while iterating the same list.
list[:] = ["Modify the list" for each_element in list "Condition Check"]
example:
list[:] = [list.remove(each_element) for each_element in list if each_element in ["data1", "data2"]]

}
func navTitleWithImageAndText(titleText: String, imageName: String) -> UIView {
// Creates a new UIView
let titleView = UIView()
// Creates a new text label
let label = UILabel()
label.text = titleText
label.sizeToFit()
label.center = titleView.center
label.textAlignment = NSTextAlignment.center
// Creates the image view
let image = UIImageView()
image.image = UIImage(named: imageName)
// Maintains the image's aspect ratio:
let imageAspect = image.image!.size.width / image.image!.size.height
// Sets the image frame so that it's immediately before the text:
let imageX = label.frame.origin.x - label.frame.size.height * imageAspect
let imageY = label.frame.origin.y
let imageWidth = label.frame.size.height * imageAspect
let imageHeight = label.frame.size.height
image.frame = CGRect(x: imageX, y: imageY, width: imageWidth, height: imageHeight)
image.contentMode = UIView.ContentMode.scaleAspectFit
// Adds both the label and image view to the titleView
titleView.addSubview(label)
titleView.addSubview(image)
// Sets the titleView frame to fit within the UINavigation Title
titleView.sizeToFit()
return titleView
}
In MySQL, certain words like SELECT
, INSERT
, DELETE
etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.
As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):
Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.
...
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.
...
The identifier quote character is the backtick ("
`
"):
A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.
You have two options.
The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.
Doing this has a couple of advantages:
It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.
The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.
Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.
If renaming the table or column isn't possible, wrap the offending identifier in backticks (`
) as described in the earlier quote from 10.2 Schema Object Names.
An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):
mysql> CREATE TABLE interval (begin INT, end INT); ERROR 1064 (42000): You have an error in your SQL syntax. near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT); Query OK, 0 rows affected (0.01 sec)
Similarly, the query from the question can be fixed by wrapping the keyword key
in backticks, as shown below:
INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)"; ^ ^
Add your <script>
to the bottom of your <body>
, or add an event listener for DOMContentLoaded
following this StackOverflow question.
If that script executes in the <head>
section of the code, document.getElementsByClassName(...)
will return an empty array because the DOM is not loaded yet.
You're getting the Type Error
because you're referencing search_span[0]
, but search_span[0]
is undefined
.
This works when you execute it in Dev Tools because the DOM is already loaded.

I presume the value is a representation in percentage - if not convert it to a valid percentage total, then add the % sign and convert the column to varchar.
you can also just add the vm to your machine

I encountered this error when I was upgrading my project from Swift 4 to 5. I first updated all my pods to their latest versions. When I built, some pods showed this error.
The following steps resolved this issue for me:
Podfile
pod install
to remove all installed podspod deintegrate
to remove support for CocoaPodsPodfile.lock
and .xcworkspace
from my project so no
CocoaPods anymore.xcodeproj
filePodfile
pod install
to reintegrate CocoaPods and add my pods.xcworkspace
fileNow I have only errors in my own project code related with difference in Swift version I made. My job now is to fix them.
Hear it from the Horse's Mouth : APUE (Richard Stevens).
To the kernel, all open files are referred to by File Descriptors. A file descriptor is a non-negative number.
When we open an existing file or create a new file, the kernel returns a file descriptor to the process. The kernel maintains a table of all open file descriptors, which are in use. The allotment of file descriptors is generally sequential and they are allotted to the file as the next free file descriptor from the pool of free file descriptors. When we closes the file, the file descriptor gets freed and is available for further allotment.
See this image for more details :
When we want to read or write a file, we identify the file with the file descriptor that was returned by open() or create() function call, and use it as an argument to either read() or write().
It is by convention that, UNIX System shells associates the file descriptor 0 with Standard Input of a process, file descriptor 1 with Standard Output, and file descriptor 2 with Standard Error.
File descriptor ranges from 0 to OPEN_MAX. File descriptor max value can be obtained with ulimit -n
. For more information, go through 3rd chapter of APUE Book.
I've found timezone.make_aware(datetime.datetime.now())
is helpful in django (I'm on 1.9.1). Unfortunately you can't simply make a datetime
object offset-aware, then timetz()
it. You have to make a datetime
and make comparisons based on that.
GitHub could make this a lot better with minimal work. Here is a work-around.
I think you want something more like
[Your Title](your-project-name/tree/master/your-subfolder)
or to point to the README itself
[README](your-project-name/blob/master/your-subfolder/README.md)
Try simple & lightweight PathJS lib.
Simple example:
Path.map("#/page").to(function(){
alert('page!');
});
Put it in the viewDidLoad
method
navigationItem.hidesBackButton = true
It happened when I added a Swift
file into an Objective-C
project .
So , in this situation what you can do is . .
Select
MY_FILE.Swift
>>
Delete
>>
Remove Reference
Select
MY_FOLDER
>>
Add
MY_FILE.Swift
Voila ! You are good to go .
Yet another alternative:
public String join(Collection<String> collection, String seperator) {
if (collection.isEmpty()) return "";
Iterator<String> iter = collection.iterator();
StringBuilder sb = new StringBuilder(iter.next());
while (iter.hasNext()) {
sb.append(seperator);
sb.append(iter.next());
}
return sb.toString();
}
The most common way of doing this is to include the binary as base-64 in an element. However, this is a workaround, and adds a bit of volume to the file.
For example, this is the bytes 00 to 09 (note we needed 16 bytes to encode 10 bytes worth of data):
<xml><image>AAECAwQFBgcICQ==</image></xml>
how you do this encoding varies per architecture. For example, with .NET you might use Convert.ToBase64String
, or XmlWriter.WriteBase64
.
Template/HTML File (component.ts)
<select>
<option *ngFor="let v of values" [value]="v" (ngModelChange)="onChange($event)">
{{v.name}}
</option>
</select>
Typescript File (component.ts)
values = [
{ id: 3432, name: "Recent" },
{ id: 3442, name: "Most Popular" },
{ id: 3352, name: "Rating" }
];
onChange(cityEvent){
console.log(cityEvent); // It will display the select city data
}
(ngModelChange) is the @Output of the ngModel directive. It fires when the model changes. You cannot use this event without the ngModel directive
I think you just need to add 2 more options (contentType
and dataType
):
$('#my_get_related_keywords').click(function() {
$.ajax({
type: "POST",
url: "HERE PUT THE PATH OF YOUR SERVICE OR PAGE",
data: '{"HERE YOU CAN PUT DATA TO PASS AT THE SERVICE"}',
contentType: "application/json; charset=utf-8", // this
dataType: "json", // and this
success: function (msg) {
//do something
},
error: function (errormessage) {
//do something else
}
});
}
For anyone who wants to find the build directory from a script but does not want to change it, run the following to get a list of all the build settings that point to a folder in DerivedData:
xcodebuild -showBuildSettings | grep DerivedData
If you run custom targets and schemes, please put them there as well:
xcodebuild -workspace "Foo.xcworkspace" -scheme "Bar" -sdk iphonesimulator -configuration Debug -showBuildSettings | grep DerivedData
Look at the output to locate the setting output that you want and then:
xcodebuild -showBuildSettings | grep SYMROOT | cut -d "=" -f 2 - | sed 's/^ *//'
The last part cuts the string at the equal sign and then trims the whitespace at the beginning.
A bit simpler one-liner:
import os
from itertools import product, chain
chain.from_iterable([[os.sep.join(w) for w in product([i[0]], i[2])] for i in os.walk(dir)])
For people landing here from google like me and just want to build containers using multiple docker-compose files with one shared service:
Sometimes you have different projects that would share e.g. a database docker container. Only the first run should start the DB-Docker, the second should be detect that the DB is already running and skip this. To achieve such a behaviour we need the Dockers to lay in the same network and in the same project. Also the docker container name needs to be the same.
1st: Set the same network and container name in docker-compose
docker-compose in project 1:
version: '3'
services:
service1:
depends_on:
- postgres
# ...
networks:
- dockernet
postgres:
container_name: project_postgres
image: postgres:10-alpine
restart: always
# ...
networks:
- dockernet
networks:
dockernet:
docker-compose in project 2:
version: '3'
services:
service2:
depends_on:
- postgres
# ...
networks:
- dockernet
postgres:
container_name: project_postgres
image: postgres:10-alpine
restart: always
# ...
networks:
- dockernet
networks:
dockernet:
2nd: Set the same project using -p
param or put both files in the same directory.
docker-compose -p {projectname} up
