Vlookup
is good if the reference values (column A, sheet 1) are in ascending order. Another option is Index and Match, which can be used no matter the order (As long as the values in column a, sheet 1 are unique)
This is what you would put in column B on sheet 2
=INDEX(Sheet1!A$1:B$6,MATCH(A1,Sheet1!A$1:A$6),2)
Setting Sheet1!A$1:B$6
and Sheet1!A$1:A$6
as named ranges makes it a little more user friendly.
simply use the form_validation class of codeigniter:
strip_image_tags($str).
$this->load->library('form_validation');
$this->form_validation->set_rules('nombre_campo', 'label', 'strip_image_tags');
Checking your linked site, you may include a script tag passing a ?var=desiredVarName
parameter which will be set as a global variable containing the IP address:
<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
<!-- ^^^^ -->
<script>alert(myip);</script>
I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.
In case your page is served using the https
protocol, most browsers will block content in the same page served using the http
protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:
<script>
var myip;
function ip_callback(o) {
myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>
Edit: Apparently, this https
service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json
The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script>
tag, this way you don't need to rely on external resources. For example:
PHP:
<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>
There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.
C#:
<script>var myip = '<%= Request.UserHostAddress %>';</script>
It's the Ternary operator a.k.a Elvis operator (google it :P) you are looking for.
echo $address['street2'] ?: 'Empty';
It returns the value of the variable or default if the variable is empty.
You should have a look at Boost.Python. Here is the short introduction taken from their website:
The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler. It is designed to wrap C++ interfaces non-intrusively, so that you should not have to change the C++ code at all in order to wrap it, making Boost.Python ideal for exposing 3rd-party libraries to Python. The library's use of advanced metaprogramming techniques simplifies its syntax for users, so that wrapping code takes on the look of a kind of declarative interface definition language (IDL).
You can use myDict.has_key(keyname)
as well to validate if the key exists.
This would work only on versions lower than 3.1. has_key
has been removed from Python 3.1. You should use the in
operator if you are using Python 3.1
stored value in DB is: 5XXXXXX [where x can be any digit]
You don't mention data types - if numeric, you'll likely have to use CAST/CONVERT to change the data type to [n]varchar.
Use:
WHERE CHARINDEX(column, '5') = 1
AND CHARINDEX(column, '.') = 0 --to stop decimals if needed
AND ISNUMERIC(column) = 1
References:
i have also different cases like XXXX7XX for example, so it has to be generic.
Use:
WHERE PATINDEX('%7%', column) = 5
AND CHARINDEX(column, '.') = 0 --to stop decimals if needed
AND ISNUMERIC(column) = 1
References:
SQL Server 2000+ supports regex, but the catch is you have to create the UDF function in CLR before you have the ability. There are numerous articles providing example code if you google them. Once you have that in place, you can use:
5\d{6}
for your first example\d{4}7\d{2}
for your second exampleFor more info on regular expressions, I highly recommend this website.
Use Sum()
List<string> foo = new List<string>();
foo.Add("1");
foo.Add("2");
foo.Add("3");
foo.Add("4");
Console.Write(foo.Sum(x => Convert.ToInt32(x)));
Prints:
10
Yes... I am using Hue 3.7.0 - The Hadoop UI and to get current date/time information we can use below commands in Hive:
SELECT from_unixtime(unix_timestamp()); --/Selecting Current Time stamp/
SELECT CURRENT_DATE; --/Selecting Current Date/
SELECT CURRENT_TIMESTAMP; --/Selecting Current Time stamp/
However, in Impala you will find that only below command is working to get date/time details:
SELECT from_unixtime(unix_timestamp()); --/Selecting Current Timestamp /
Hope it resolves your query :)
set multiple css style properties in Javascript
document.getElementById("yourElement").style.cssText = cssString;
or
document.getElementById("yourElement").setAttribute("style",cssString);
Example:
document
.getElementById("demo")
.style
.cssText = "margin-left:100px;background-color:red";
document
.getElementById("demo")
.setAttribute("style","margin-left:100px; background-color:red");
Thanks, riaraos, uninstalling KB952241 was the solution for me, too. Before doing that I tried to run the installer from "Programs and Features" and from the installation DVD without success. I did not want to completely remove the VS 2008 installation but only add a few components.
Notes on my system:
Windows 7 Beta 1 Visual Studio 2008 SP1
To dismiss the keyboard (1.7.8+hotfix.2 and above) just call the method below:
FocusScope.of(context).unfocus();
Once the FocusScope.of(context).unfocus() method already check if there is focus before dismiss the keyboard it's not needed to check it. But in case you need it just call another context method: FocusScope.of(context).hasPrimaryFocus
You've an number of options, depending on how you want to play it:
isNaN(val)
Returns true if val is not a number, false if it is. In your case, this is probably what you need.
isFinite(val)
Returns true if val, when cast to a String, is a number and it is not equal to +/- Infinity
/^\d+$/.test(val)
Returns true if val, when cast to a String, has only digits (probably not what you need).
import numpy as np
import scipy.stats
def mean_confidence_interval(data, confidence=0.95):
a = 1.0 * np.array(data)
n = len(a)
m, se = np.mean(a), scipy.stats.sem(a)
h = se * scipy.stats.t.ppf((1 + confidence) / 2., n-1)
return m, m-h, m+h
you can calculate like this way.
In Linux, I normally use this command to recursively grep for a particular text within a dir
grep -rni "string" *
where,
r = recursive i.e, search subdirectories within the current directory
n = to print the line numbers to stdout
i = case insensitive search
You can also try my ServiceStack JsonSerializer it's the fastest .NET JSON serializer at the moment. It supports serializing DataContracts, any POCO Type, Interfaces, Late-bound objects including anonymous types, etc.
Basic Example
var customer = new Customer { Name="Joe Bloggs", Age=31 };
var json = JsonSerializer.SerializeToString(customer);
var fromJson = JsonSerializer.DeserializeFromString<Customer>(json);
Note: Only use Microsofts JavaScriptSerializer if performance is not important to you as I've had to leave it out of my benchmarks since its up to 40x-100x slower than the other JSON serializers.
I came across a similar problem (wanting to pull a commit that included some binary files which caused conflicts when merged), but came across a different solution that can be done entirely using git (i.e. not having to manually copy files over). I figured I'd include it here so at the very least I can remember it the next time I need it. :) The steps look like this:
% git fetch
This fetches the latest commit(s) from the remote repository (you may need to specify a remote branch name, depending on your setup), but doesn't try to merge them. It records the the commit in FETCH_HEAD
% git checkout FETCH_HEAD stuff/to/update
This takes the copy of the binary files I want and overwrites what's in the working tree with the version fetched from the remote branch. git doesn't try to do any merging, so you just end up with an exact copy of the binary file from the remote branch. Once that's done, you can add/commit the new copy just like normal.
in Short, There are 3 parameters in AsyncTask
parameters for Input use in DoInBackground(String... params)
parameters for show status of progress use in OnProgressUpdate(String... status)
parameters for result use in OnPostExcute(String... result)
Note : - [Type of parameters can vary depending on your requirement]
note! there is a difference between e.clientX
& e.clientY
and e.pageX
and e.pageY
try them both out and make sure you are using the proper one. clientX
and clientY
change based on scrolling position
If the string containing the phone number will always start this way (+33 or another country code) you should use regex to parse and get the country code and then use the library to get the country associated to the number.
Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.
Create two string data type variables namely DirPath
and FilePath
. Set the value C:\backup\ to the variable DirPath
. Do not set any value to the variable FilePath
.
Select the variable FilePath
and select F4 to view the properties. Set the EvaluateAsExpression
property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)
I have not tested , but what the main idea is: put semicolon on each query.
SqlConnection connection = new SqlConnection();
SqlCommand command = new SqlCommand();
connection.ConnectionString = connectionString; // put your connection string
command.CommandText = @"
update table
set somecol = somevalue;
insert into someTable values(1,'test');";
command.CommandType = CommandType.Text;
command.Connection = connection;
try
{
connection.Open();
}
finally
{
command.Dispose();
connection.Dispose();
}
Update: you can follow Is it possible to have multiple SQL instructions in a ADO.NET Command.CommandText property? too
Flexible Box Layout Module - 8.1. Aligning with auto margins
Auto margins on flex items have an effect very similar to auto margins in block flow:
During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via
justify-content
andalign-self
, any positive free space is distributed to auto margins in that dimension.
Therefore you could use margin-top: auto
to distribute the space between the other elements and the last element.
This will position the last element at the bottom.
p:last-of-type {
margin-top: auto;
}
.container {
display: flex;
flex-direction: column;
border: 1px solid #000;
min-height: 200px;
width: 100px;
}
p {
height: 30px;
background-color: blue;
margin: 5px;
}
p:last-of-type {
margin-top: auto;
}
_x000D_
<div class="container">
<p></p>
<p></p>
<p></p>
</div>
_x000D_
Likewise, you can also use margin-left: auto
or margin-right: auto
for the same alignment horizontally.
p:last-of-type {
margin-left: auto;
}
.container {
display: flex;
width: 100%;
border: 1px solid #000;
}
p {
height: 50px;
width: 50px;
background-color: blue;
margin: 5px;
}
p:last-of-type {
margin-left: auto;
}
_x000D_
<div class="container">
<p></p>
<p></p>
<p></p>
<p></p>
</div>
_x000D_
There are quite a few ways to work with dynamic arrays in PHP. Initialise an array:
$array = array();
Add to an array:
$array[] = "item"; // for your $arr1
$array[$key] = "item"; // for your $arr2
array_push($array, "item", "another item");
Remove from an array:
$item = array_pop($array);
$item = array_shift($array);
unset($array[$key]);
There are plenty more ways, these are just some examples.
Answer for Swift 3.0, Xcode 8
1.Make sure you set collection view delegate
class DashboardViewController: UIViewController {
@IBOutlet weak var dashboardCollectionView: UICollectionView!
override func viewDidLoad() {
super.viewDidLoad()
dashboardCollectionView.delegate = self
}
}
2.Implement UICollectionViewDelegateFlowLayout protocol, not UICollectionViewDelegate.
extension DashboardViewController: UICollectionViewDelegateFlowLayout {
fileprivate var sectionInsets: UIEdgeInsets {
return .zero
}
fileprivate var itemsPerRow: CGFloat {
return 2
}
fileprivate var interitemSpace: CGFloat {
return 5.0
}
func collectionView(_ collectionView: UICollectionView,
layout collectionViewLayout: UICollectionViewLayout,
sizeForItemAt indexPath: IndexPath) -> CGSize {
let sectionPadding = sectionInsets.left * (itemsPerRow + 1)
let interitemPadding = max(0.0, itemsPerRow - 1) * interitemSpace
let availableWidth = collectionView.bounds.width - sectionPadding - interitemPadding
let widthPerItem = availableWidth / itemsPerRow
return CGSize(width: widthPerItem, height: widthPerItem)
}
func collectionView(_ collectionView: UICollectionView,
layout collectionViewLayout: UICollectionViewLayout,
insetForSectionAt section: Int) -> UIEdgeInsets {
return sectionInsets
}
func collectionView(_ collectionView: UICollectionView,
layout collectionViewLayout: UICollectionViewLayout,
minimumLineSpacingForSectionAt section: Int) -> CGFloat {
return 0.0
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
return interitemSpace
}
}

EDIT:
I've recently earned a "Good answer" badge for this answer. While my solution is simple and working, the cleanest way to run any program or shell script at login time is described in @trisweb's answer, unless, you want interactivity.
With automator solution you can do things like next:
so, asking to run a script or quit the app, asking passwords, running other automator workflows at login time, conditionally run applications at login time and so on...
On Linux, it's may not be safe to to use _SC_NPROCESSORS_ONLN
as it's not part of POSIX standard and the sysconf manual states as much. So there's a possibility that _SC_NPROCESSORS_ONLN
may not be present:
These values also exist, but may not be standard.
[...]
- _SC_NPROCESSORS_CONF
The number of processors configured.
- _SC_NPROCESSORS_ONLN
The number of processors currently online (available).
A simple approach would be to read /proc/stat
or /proc/cpuinfo
and count them:
#include<unistd.h>
#include<stdio.h>
int main(void)
{
char str[256];
int procCount = -1; // to offset for the first entry
FILE *fp;
if( (fp = fopen("/proc/stat", "r")) )
{
while(fgets(str, sizeof str, fp))
if( !memcmp(str, "cpu", 3) ) procCount++;
}
if ( procCount == -1)
{
printf("Unable to get proc count. Defaulting to 2");
procCount=2;
}
printf("Proc Count:%d\n", procCount);
return 0;
}
Using /proc/cpuinfo
:
#include<unistd.h>
#include<stdio.h>
int main(void)
{
char str[256];
int procCount = 0;
FILE *fp;
if( (fp = fopen("/proc/cpuinfo", "r")) )
{
while(fgets(str, sizeof str, fp))
if( !memcmp(str, "processor", 9) ) procCount++;
}
if ( !procCount )
{
printf("Unable to get proc count. Defaulting to 2");
procCount=2;
}
printf("Proc Count:%d\n", procCount);
return 0;
}
The same approach in shell using grep:
grep -c ^processor /proc/cpuinfo
Or
grep -c ^cpu /proc/stat # subtract 1 from the result
Try looking at http-rest-client
https://github.com/g00dnatur3/http-rest-client
Here is a simple example:
RestClient client = RestClient.builder().build();
String geocoderUrl = "http://maps.googleapis.com/maps/api/geocode/json"
Map<String, String> params = Maps.newHashMap();
params.put("address", "beverly hills 90210");
params.put("sensor", "false");
JsonNode node = client.get(geocoderUrl, params, JsonNode.class);
The library takes care of json serialization and binding for you.
Here is another example,
RestClient client = RestClient.builder().build();
String url = ...
Person person = ...
Header header = client.create(url, person);
if (header != null) System.out.println("Location header is:" + header.value());
And one last example,
RestClient client = RestClient.builder().build();
String url = ...
Person person = client.get(url, null, Person.class); //no queryParams
Cheers!
A solution is already selected. However, I post this solution for those who want to use an alternative approach:
// use LinkedHashMap if you want to read values from the hashmap in the same order as you put them into it
private ArrayList<String> getMapValueAt(LinkedHashMap<String, ArrayList<String>> hashMap, int index)
{
Map.Entry<String, ArrayList<String>> entry = (Map.Entry<String, ArrayList<String>>) hashMap.entrySet().toArray()[index];
return entry.getValue();
}
If you encounter asynchronous functions, and you want to make sure that before executing the code it finishes its task, we can always use the callback capability.
For example:
var ctr = 0;
posts.forEach(function(element, index, array){
asynchronous(function(data){
ctr++;
if (ctr === array.length) {
functionAfterForEach();
}
})
});
Note: functionAfterForEach
is the function to be executed after foreach tasks are finished. asynchronous
is the asynchronous function executed inside foreach.
Just add another join:
SELECT dashboard_data.headline,
dashboard_data.message,
dashboard_messages.image_id,
images.filename
FROM dashboard_data
INNER JOIN dashboard_messages
ON dashboard_message_id = dashboard_messages.id
INNER JOIN images
ON dashboard_messages.image_id = images.image_id
you could simply do:
var newImage = new Image();
newImage.src = "someImg.jpg";
if(document.images)
{
document.images.yourImageElementName.src = newImage.src;
}
Simple :)
If you want to see all the Enviroment Variables on execution time just write in some nodejs file like server.js:
console.log(process.env);
You are using the wrong build.gradle
file.
In your top-level file you can't define an android
block.
Just move this part inside the module/build.gradle
file.
android {
compileSdkVersion 17
buildToolsVersion '23.0.0'
}
dependencies {
compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'
<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>
Easy as that.
Or without JS
<a href="http://yahoo.com" target="_blank">test</a>
sequence info : max value
SELECT * FROM information_schema.sequences;
sequence info : last value
SELECT * FROM <sequence_name>
Start writing, then just press CTRL+SPACE and there you go ...
I was getting nothing for any $_GET["..."]
(e.g print_r($_GET)
gave an empty array) yet $_SERVER['REQUEST_URI']
showed stuff should be there. In the end it turned out that I was only getting to the web page because my .htaccess was redirecting it there (my 404 handler was the same .php file, and I had made a typo in the browser when testing).
Simply changing the name meant the same php code worked once the 404 redirection wasn't kicking in!
So there are ways $_GET
can return nothing even though the php code may be correct.
A subtle alternative to MaxNoe's answer where you aren't explicitly setting the ticks but instead setting the cadence.
import matplotlib.pyplot as plt
from matplotlib.ticker import (AutoMinorLocator, MultipleLocator)
fig, ax = plt.subplots(figsize=(10, 8))
# Set axis ranges; by default this will put major ticks every 25.
ax.set_xlim(0, 200)
ax.set_ylim(0, 200)
# Change major ticks to show every 20.
ax.xaxis.set_major_locator(MultipleLocator(20))
ax.yaxis.set_major_locator(MultipleLocator(20))
# Change minor ticks to show every 5. (20/4 = 5)
ax.xaxis.set_minor_locator(AutoMinorLocator(4))
ax.yaxis.set_minor_locator(AutoMinorLocator(4))
# Turn grid on for both major and minor ticks and style minor slightly
# differently.
ax.grid(which='major', color='#CCCCCC', linestyle='--')
ax.grid(which='minor', color='#CCCCCC', linestyle=':')
To change the button background we can follow 2 methods
In the button OnClick, just add this code:
public void onClick(View v) {
if(v == buttonName) {
buttonName.setBackgroundDrawable
(getResources().getDrawable(R.drawable.imageName_selected));
}
}
2.Create button_background.xml in the drawable folder.(using xml)
res -> drawable -> button_background.xml
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true"
android:drawable="@drawable/tabs_selected" /> <!-- selected-->
<item android:state_pressed="true"
android:drawable="@drawable/tabs_selected" /> <!-- pressed-->
<item android:drawable="@drawable/tabs_selected"/>
</selector>
Now set the above file in button's background file.
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/button_background"/>
(or)
Button tiny = (Button)findViewById(R.id.tiny);
tiny.setBackgroundResource(R.drawable.abc);
2nd method is better for setting the background fd button
For me I had issues with history and location... As the accepted answer using window before history and location (i.e) window.history and window.location solved mine
To push over old repo.
git push -u origin master --force

It should be noted that the documentation recommends using a Layout
rather than Canvas.drawText
directly. My full answer about using a StaticLayout
is here, but I will provide a summary below.
String text = "This is some text.";
TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);
int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);
Here is a fuller example in the context of a custom view:
public class MyView extends View {
String mText = "This is some text.";
TextPaint mTextPaint;
StaticLayout mStaticLayout;
// use this constructor if creating MyView programmatically
public MyView(Context context) {
super(context);
initLabelView();
}
// this constructor is used when created from xml
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
initLabelView();
}
private void initLabelView() {
mTextPaint = new TextPaint();
mTextPaint.setAntiAlias(true);
mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
mTextPaint.setColor(0xFF000000);
// default to a single line of text
int width = (int) mTextPaint.measureText(mText);
mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
// New API alternate
//
// StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
// .setAlignment(Layout.Alignment.ALIGN_NORMAL)
// .setLineSpacing(1, 0) // multiplier, add
// .setIncludePad(false);
// mStaticLayout = builder.build();
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Tell the parent layout how big this view would like to be
// but still respect any requirements (measure specs) that are passed down.
// determine the width
int width;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
if (widthMode == MeasureSpec.EXACTLY) {
width = widthRequirement;
} else {
width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
if (widthMode == MeasureSpec.AT_MOST) {
if (width > widthRequirement) {
width = widthRequirement;
// too long for a single line so relayout as multiline
mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
}
}
}
// determine the height
int height;
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
if (heightMode == MeasureSpec.EXACTLY) {
height = heightRequirement;
} else {
height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
if (heightMode == MeasureSpec.AT_MOST) {
height = Math.min(height, heightRequirement);
}
}
// Required call: set width and height
setMeasuredDimension(width, height);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
// do as little as possible inside onDraw to improve performance
// draw the text on the canvas after adjusting for padding
canvas.save();
canvas.translate(getPaddingLeft(), getPaddingTop());
mStaticLayout.draw(canvas);
canvas.restore();
}
}
I have set OnGroupExpandListener and override onGroupExpand() as:
and use setSelectionFromTop() method which Sets the selected item and positions the selection y pixels from the top edge of the ListView. (If in touch mode, the item will not be selected but it will still be positioned appropriately.) (android docs)
yourlist.setOnGroupExpandListener (new ExpandableListView.OnGroupExpandListener()
{
@Override
public void onGroupExpand(int groupPosition) {
expList.setSelectionFromTop(groupPosition, 0);
//your other code
}
});
get ID of ImageView as
ImageView imgFp = (ImageView) findViewById(R.id.imgFp);
then Use
imgFp.setImageResource(R.drawable.fpscan);
to set source image programatically instead from XML.
array_slice()
can be used to extract parts of the array, and the union array operator (+
) can recombine the parts.
$res = array_slice($array, 0, 3, true) +
array("my_key" => "my_value") +
array_slice($array, 3, count($array)-3, true);
This example:
$array = array(
'zero' => '0',
'one' => '1',
'two' => '2',
'three' => '3',
);
$res = array_slice($array, 0, 3, true) +
array("my_key" => "my_value") +
array_slice($array, 3, count($array) - 1, true) ;
print_r($res);
gives:
Array ( [zero] => 0 [one] => 1 [two] => 2 [my_key] => my_value [three] => 3 )
Easiest way to check if they are authenticated is Request.User.IsAuthenticated
I think (from memory)
It is quite possible that an end user wants to have Git ignore the ".gitignore" file simply because the IDE specific folders created by Eclipse are probably not the same as NetBeans or another IDE. So to keep the source code IDE antagonistic it makes life easy to have a custom git ignore that isn't shared with the entire team as individual developers might be using different IDE's.
If you don't care about IE =6, you could use pure CSS ...
.forum:hover { background-color: #380606; }
.forum { color: white; }_x000D_
.forum:hover { background-color: #380606 !important; }_x000D_
/* we use !important here to override specificity. see http://stackoverflow.com/q/5805040/ */_x000D_

<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>
_x000D_
With jQuery, usually it is better to create a specific class for this style:
.forum_hover { background-color: #380606; }
and then apply the class on mouseover, and remove it on mouseout.
$('.forum').hover(function(){$(this).toggleClass('forum_hover');});
$(document).ready(function(){_x000D_
$('.forum').hover(function(){$(this).toggleClass('forum_hover');});_x000D_
});
_x000D_
.forum_hover { background-color: #380606 !important; }_x000D_

If you must not modify the class, you could save the original background color in .data()
:
$('.forum').data('bgcolor', '#380606').hover(function(){
var $this = $(this);

Even when the question is regarding Java 7, I think it adds value to know that from Java 11 onward, there is a static method in Path
class that allows to do this straight away:
With all the path in one String:
Path.of("/tmp/foo");
With the path broken down in several Strings:
Path.of("/tmp","foo");
you can use this file (https://github.com/louisremi/background-size-polyfill “background-size polyfill”) for IE8 that is really simple to use:
.selector {
background-size: cover;
-ms-behavior: url(/backgroundsize.min.htc);
}
I just had the same issue with Font Awesome. Turned out this was caused by a problem with FTP. The file was uploaded as text (ASCII) instead of binary, which corrupted the file. I simply changed my FTP software to binary, re-uploaded the font files, and then it all worked.
https://css-tricks.com/forums/topic/custom-fonts-returns-failed-to-decode-downloaded-font/ this helped me in the end I had the same issue with FTP transferring files as text
In my case the file name was too long, and got the same error. Once shortened below 200 chars worked fine. (limit might be 250?)
Well, I do my coding in NetBeans 8.1:
First: Create a new project, select Java application and name your project.
Then modify your code after public class to look like the following:
/**
* @param args the command line arguments
* @throws java.io.FileNotFoundException
*/
public static void main(String[] args) throws FileNotFoundException {
try (Scanner scanner = new Scanner(new File("C:\\Users\\YourName\\Folder\\file.csv"))) {
scanner.useDelimiter(",");
while(scanner.hasNext()){
System.out.print(scanner.next()+"|");
}}
}
}
For kdiff3 you can use:
git config --global merge.tool kdiff3
git config --global mergetool.kdiff3.path "C:/Program Files/KDiff3/kdiff3.exe"
git config --global mergetool.kdiff3.trustExitCode false
git config --global diff.guitool kdiff3
git config --global difftool.kdiff3.path "C:/Program Files/KDiff3/kdiff3.exe"
git config --global difftool.kdiff3.trustExitCode false
0 is, by definition, a magic number. EXIT_SUCCESS is almost universally equal to 0, happily enough. So why not just return/exit 0?
exit(EXIT_SUCCESS); is abundantly clear in meaning.
exit(0); on the other hand, is counterintuitive in some ways. Someone not familiar with shell behavior might assume that 0 == false == bad, just like every other usage of 0 in C. But no - in this one special case, 0 == success == good. For most experienced devs, not going to be a problem. But why trip up the new guy for absolutely no reason?
tl;dr - if there's a defined constant for your magic number, there's almost never a reason not to used the constant in the first place. It's more searchable, often clearer, etc. and it doesn't cost you anything.
In IntelliJ Idea 2019 you can find scope "Problems" under the "Project" view. Default scope is "Project".
I had to enable it in my BIOS as shown below (for Asus):
Short Answer: value >= 0 means that the servlet is loaded when the web-app is deployed or when the server starts. value < 0 : servlet is loaded whenever the container feels like.
Long answer (from the spec):
The load-on-startup element indicates that this servlet should be loaded (instantiated and have its init() called) on the startup of the web application. The optional contents of these element must be an integer indicating the order in which the servlet should be loaded. If the value is a negative integer, or the element is not present, the container is free to load the servlet whenever it chooses. If the value is a positive 128 integer or 0, the container must load and initialize the servlet as the application is deployed. The container must guarantee that servlets marked with lower integers are loaded before servlets marked with higher integers. The container may choose the order of loading of servlets with the same load-on-start-up value.
Programmatically, you can do this:
btn.BorderBrush = new SolidColorBrush(Colors.Transparent);
I face the same problem , and after a lot of work and search , I figured out the solution : I just cleaned the project then build the apk. -Build->Clean Project -Build-> Build APK(s) I hope it is useful.....
This is an old question asked two years prior to my answer, I am going to post what worked for me anyways.
In my working directory I have two files: Dockerfile & provision.sh
Dockerfile:
FROM centos:6.8
# put the script in the /root directory of the container
COPY provision.sh /root
# execute the script inside the container
RUN /root/provision.sh
EXPOSE 80
# Default command
CMD ["/bin/bash"]
provision.sh:
#!/usr/bin/env bash
yum upgrade
I was able to make the file in the docker container executable by setting the file outside the container as executable chmod 700 provision.sh
then running docker build .
.
to stop the service:
sc stop mysql56
and to start it:
sc start mysql56
you might need to change the mysql56
to whatever your version is.
If you need a number greater than 999,999.00 you will have a problem.
These are only good for numbers less than 1 million, 1,000,000.
They only remove 1 or 2 commas.
Here the script that can remove up to 12 commas:
function uncomma(x) {
var string1 = x;
for (y = 0; y < 12; y++) {
string1 = string1.replace(/\,/g, '');
}
return string1;
}
Modify that for loop if you need bigger numbers.
you can attach a listener to keyUp
event for the document.
Also, if you want to make sure, any other key is not pressed along with Esc
key, you can use values of ctrlKey
, altKey
, and shifkey
.
document.addEventListener('keydown', (event) => {
if (event.key === 'Escape') {
//if esc key was not pressed in combination with ctrl or alt or shift
const isNotCombinedKey = !(event.ctrlKey || event.altKey || event.shiftKey);
if (isNotCombinedKey) {
console.log('Escape key was pressed with out any group keys')
}
}
});
Slightly twisted, but an iterator block to do it:
public static IEnumerable<string> Lines(this string Text)
{
int cIndex = 0;
int nIndex;
while ((nIndex = Text.IndexOf(Environment.NewLine, cIndex + 1)) != -1)
{
int sIndex = (cIndex == 0 ? 0 : cIndex + 1);
yield return Text.Substring(sIndex, nIndex - sIndex);
cIndex = nIndex;
}
yield return Text.Substring(cIndex + 1);
}
You can then call:
var result = input.Lines().ToArray();
Put all radio buttons for a group in a container object like a Panel
or a GroupBox
. That will automatically group them together in Windows Forms.
In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.
So register the ChildComponent in Shared Module manually.
Here is how I did it using only the default bootstrap CSS v3.3.1:
<div class="form-group">
<label class="control-label">Start:</label>
<div class="input-group">
<input type="text" class="form-control" aria-describedby="start-date">
<span class="input-group-addon" id="start-date"><span class="glyphicon glyphicon-calendar"></span></span>
</div>
</div>
And this is how it looks:
You can get all details by order object.
// Get $order object from order ID
$order = wc_get_order( $order_id );
// Now you have access to (see above)...
if ( $order ) {
// Get Order ID and Key
$order->get_id();
$order->get_order_key();
// Get Order Totals $0.00
$order->get_formatted_order_total();
$order->get_cart_tax();
$order->get_currency();
$order->get_discount_tax();
$order->get_discount_to_display();
$order->get_discount_total();
$order->get_fees();
$order->get_formatted_line_subtotal();
$order->get_shipping_tax();
$order->get_shipping_total();
$order->get_subtotal();
$order->get_subtotal_to_display();
$order->get_tax_location();
$order->get_tax_totals();
$order->get_taxes();
$order->get_total();
$order->get_total_discount();
$order->get_total_tax();
$order->get_total_refunded();
$order->get_total_tax_refunded();
$order->get_total_shipping_refunded();
$order->get_item_count_refunded();
$order->get_total_qty_refunded();
$order->get_qty_refunded_for_item();
$order->get_total_refunded_for_item();
$order->get_tax_refunded_for_item();
$order->get_total_tax_refunded_by_rate_id();
$order->get_remaining_refund_amount();
}
Operators Overloadability
+, -, *, /, %, &, |, <<, >> All C# binary operators can be overloaded.
+, -, !, ~, ++, --, true, false All C# unary operators can be overloaded.
==, !=, <, >, <= , >= All relational operators can be overloaded,
but only as pairs.
&&, || They can't be overloaded
() (Conversion operator) They can't be overloaded
+=, -=, *=, /=, %= These compound assignment operators can be
overloaded. But in C#, these operators are
automatically overloaded when the respective
binary operator is overloaded.
=, . , ?:, ->, new, is, as, sizeof These operators can't be overloaded
[ ] Can be overloaded but not always!
For bracket:
public Object this[int index]
{
}
The array indexing operator cannot be overloaded; however, types can define indexers, properties that take one or more parameters. Indexer parameters are enclosed in square brackets, just like array indices, but indexer parameters can be declared to be of any type (unlike array indices, which must be integral).
From MSDN
All you need is a control that you can set the text of, and an UpdatePanel if the exception occurs during a postback.
If occurs during a postback: markup:
<ajax:UpdatePanel id="ErrorUpdatePanel" runat="server" UpdateMode="Coditional">
<ContentTemplate>
<asp:TextBox id="ErrorTextBox" runat="server" />
</ContentTemplate>
</ajax:UpdatePanel>
code:
try
{
do something
}
catch(YourException ex)
{
this.ErrorTextBox.Text = ex.Message;
this.ErrorUpdatePanel.Update();
}
The only difference between the RANK() and DENSE_RANK() functions is in cases where there is a “tie”; i.e., in cases where multiple values in a set have the same ranking. In such cases, RANK() will assign non-consecutive “ranks” to the values in the set (resulting in gaps between the integer ranking values when there is a tie), whereas DENSE_RANK() will assign consecutive ranks to the values in the set (so there will be no gaps between the integer ranking values in the case of a tie).
For example, consider the set {25, 25, 50, 75, 75, 100}. For such a set, RANK() will return {1, 1, 3, 4, 4, 6} (note that the values 2 and 5 are skipped), whereas DENSE_RANK() will return {1,1,2,3,3,4}.
how about like this
function isint(str){
if(str.match(/\d/g).length==str.length){
return true;
}
else {
return false
}
}
If you find boost::assign::map_list_of
useful, but can't use it for some reason, you could write your own:
template<class K, class V>
struct map_list_of_type {
typedef std::map<K, V> Map;
Map data;
map_list_of_type(K k, V v) { data[k] = v; }
map_list_of_type& operator()(K k, V v) { data[k] = v; return *this; }
operator Map const&() const { return data; }
};
template<class K, class V>
map_list_of_type<K, V> my_map_list_of(K k, V v) {
return map_list_of_type<K, V>(k, v);
}
int main() {
std::map<int, char> example =
my_map_list_of(1, 'a') (2, 'b') (3, 'c');
cout << example << '\n';
}
It's useful to know how such things work, especially when they're so short, but in this case I'd use a function:
struct A {
static map<int, int> const m;
};
namespace {
map<int,int> create_map() {
map<int, int> m;
m[1] = 2; // etc.
return m;
}
}
map<int, int> const A::m = create_map();
I know this is an old thread and so are answers here. Adding this answer for future reference:
Add a recycle view in your layout
<android.support.v7.widget.RecyclerView
android:id="@+id/wifiList"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
Create a layout to display list items (list_item.xml)
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:padding="5dp"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="wrap_content">
<android.support.v7.widget.AppCompatTextView
android:id="@+id/ssid"
android:text="@string/app_name"
android:layout_width="match_parent"
android:textSize="17sp"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v7.widget.CardView>
Now create a minimal Adapter to hold data, code here is self explanatory
class WifiAdapter(private val wifiList: ArrayList<ScanResult>) : RecyclerView.Adapter<WifiAdapter.ViewHolder>() {
// holder class to hold reference
inner class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
//get view reference
var ssid: TextView = view.findViewById(R.id.ssid) as TextView
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
// create view holder to hold reference
return ViewHolder( LayoutInflater.from(parent.context).inflate(R.layout.list_item, parent, false))
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
//set values
holder.ssid.text = wifiList[position].SSID
}
override fun getItemCount(): Int {
return wifiList.size
}
// update your data
fun updateData(scanResult: ArrayList<ScanResult>) {
wifiList.clear()
notifyDataSetChanged()
wifiList.addAll(scanResult)
notifyDataSetChanged()
}
}
Add this class to handle Single click and long click events on List Items
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {
public interface ClickListener {
void onClick(View view, int position);
void onLongClick(View view, RecyclerView recyclerView, int position);
}
private GestureDetector gestureDetector;
private ClickListener clickListener;
public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener) {
this.clickListener = clickListener;
gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}
@Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null) {
clickListener.onLongClick(child,recyclerView, recyclerView.getChildPosition(child));
}
}
});
}
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
View child = rv.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
clickListener.onClick(child, rv.getChildPosition(child));
}
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
Lastly Set your adapter to Recycler View and add Touch Listener to start intercepting touch event for single or double tap on list items
wifiAdapter = WifiAdapter(ArrayList())
wifiList.apply {
// vertical layout
layoutManager = LinearLayoutManager(applicationContext)
// set adapter
adapter = wifiAdapter
// Touch handling
wifiList.addOnItemTouchListener(RecyclerTouchListener(applicationContext, wifiList, object : RecyclerTouchListener.ClickListener {
override fun onClick(view: View?, position: Int) {
Toast.makeText(applicationContext, "RV OnCLickj " + position, Toast.LENGTH_SHORT).show()
}
override fun onLongClick(view: View, recyclerView: RecyclerView, position: Int) {
Toast.makeText(applicationContext, "RV OnLongCLickj " + position, Toast.LENGTH_SHORT).show()
}
}
))
}
Bonus ; Update Data
wifiAdapter.updateData(mScanResults as ArrayList<ScanResult>)
Result:
If you don't want any decimals when the resulting decimals are all zeroes, something like this would work:
String fixedDecimals(double d, int decimals, {bool removeZeroDecimals = true}){
double mod = pow(10.0, decimals);
double result = ((d * mod).round().toDouble() / mod);
if( removeZeroDecimals && result - (result.truncate()) == 0.0 ) decimals = 0;
return result.toStringAsFixed(decimals);
}
This will simply output 9
instead of 9.00
if the input is 9.004
and you want 2 decimals.
Please read the $.ajax
documentation, this is a covered topic.
$.ajax({
url: "test.html",
error: function(){
// will fire when timeout is reached
},
success: function(){
//do something
},
timeout: 3000 // sets timeout to 3 seconds
});
You can get see what type of error was thrown by accessing the textStatus parameter of the error: function(jqXHR, textStatus, errorThrown)
option. The options are "timeout", "error", "abort", and "parsererror".

Chris pretty much sums up what w3wp is. In order to disable the warning, go to this registry key:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\Debugger
And set the value DisableAttachSecurityWarning

You can connect an Android Phone via USB cable and then it will show the device in the bottom bar.(Please note ADB must be installed. Click here for more)
Or you can completely install Android Studio and setup emulator from there and run the emulator. Then VS Code will recogzine the emulator and show at the bottom bar.
See http://msdn.microsoft.com/en-us/library/ms187928.aspx
You can concatenate it:
SELECT CONVERT(VARCHAR(10), GETDATE(), 104) + ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)
You can do so by these ways.
Add watchpoint
and while debugging you can see variable in debugger window perspective under variable tab.
OR
Add System.out.println("variable = " + variable);
and see in console.
This may happen because of the old and new IP address I have faced same issue which was solve by below method:
vim /etc/zabbix/web/zabbix.conf.php
$ZBX_SERVER = new ip address
then restart zabbix server
// CREATE anim
// CREATE animation,animation2 xml // animation like fade out
Intent myIntent1 = new Intent(getApplicationContext(), Attend.class);
Bundle bndlanimation1 = ActivityOptions.makeCustomAnimation(getApplicationContext(),
R.anim.animation, R.anim.animation2).toBundle();
tartActivity(myIntent1, bndlanimation1);
The clone is a shallow copy of the array.
This test code prints:
[1, 2] / [1, 2] [100, 200] / [100, 2]
because the MutableInteger
is shared in both arrays as objects[0]
and objects2[0]
, but you can change the reference objects[1]
independently from objects2[1]
.
import java.util.Arrays;
public class CloneTest {
static class MutableInteger {
int value;
MutableInteger(int value) {
this.value = value;
}
@Override
public String toString() {
return Integer.toString(value);
}
}
public static void main(String[] args) {
MutableInteger[] objects = new MutableInteger[] {
new MutableInteger(1), new MutableInteger(2) };
MutableInteger[] objects2 = objects.clone();
System.out.println(Arrays.toString(objects) + " / " +
Arrays.toString(objects2));
objects[0].value = 100;
objects[1] = new MutableInteger(200);
System.out.println(Arrays.toString(objects) + " / " +
Arrays.toString(objects2));
}
}
This should work:
/^((?!PART).)*$/
If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:
/^(?!PART)/
The (?!...)
syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/
." The site I've linked explains this far better than I can, but I'll try to break this down:
^ #Start matching from the beginning of the string.
(?!PART) #This position must not be followed by the string "PART".
. #Matches any character except line breaks (it will include those in single-line mode).
$ #Match all the way until the end of the string.
The ((?!xxx).)*
idiom is probably hardest to understand. As we saw, (?!PART)
looks at the string ahead and says that whatever comes next can't match the subpattern /PART/
. So what we're doing with ((?!xxx).)*
is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.
The ^
and $
anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.
Since we do have ^
and $
, if PART were anywhere in the string, one of the characters would match (?=PART).
and the overall match would fail. Hope that's clear enough to be helpful.
First, list your queues:
rabbitmqadmin list queues name
Then from the list, you'll need to manually delete them one by one:
rabbitmqadmin delete queue name='queuename'
Because of the output format, doesn't appear you can grep the response from list queues
. Alternatively, if you're just looking for a way to clear everything (read: reset all settings, returning the installation to a default state), use:
rabbitmqctl stop_app
rabbitmqctl reset # Be sure you really want to do this!
rabbitmqctl start_app

Using this method makes it unneccessary to set the theme in the AlertDialog builder.
In http://bugs.jquery.com/ticket/1886 it becomes obvious that the jQuery devs have serious mental issues reg. functional programming inspired additions. Somehow it's good to have some fundamental things (like map) but not others (like reduce), unless it reduces jQuery's overall filesize. Go figure.
Helpfully, someone placed code to use the normal reduce function for jQuery arrays:
$.fn.reduce = [].reduce;
Now we can use a simple reduce function to create a summation:
//where X is a jQuery array
X.reduce(function(a,b){ return a + b; });
// (change "a" into parseFloat("a") if the first a is a string)
Lastly, as some older browsers hadn't yet implemented reduce, a polyfill can be taken from MDN (it's big but I guess it has the exact same behavior, which is desirable):
if ( 'function' !== typeof Array.prototype.reduce ) {
Array.prototype.reduce = function( callback /*, initialValue*/ ) {
'use strict';
if ( null === this || 'undefined' === typeof this ) {
throw new TypeError(
'Array.prototype.reduce called on null or undefined' );
}
if ( 'function' !== typeof callback ) {
throw new TypeError( callback + ' is not a function' );
}
var t = Object( this ), len = t.length >>> 0, k = 0, value;
if ( arguments.length >= 2 ) {
value = arguments[1];
} else {
while ( k < len && ! k in t ) k++;
if ( k >= len )
throw new TypeError('Reduce of empty array with no initial value');
value = t[ k++ ];
}
for ( ; k < len ; k++ ) {
if ( k in t ) {
value = callback( value, t[k], k, t );
}
}
return value;
};
}
It's quite an old topic, but since it is returned when searching for "django list field" I'll share the custom django list field code I modified to work with Python 3 and Django 2. It supports the admin interface now and not uses eval (which is a huge security breach in Prashant Gaur's code).
from django.db import models
from typing import Iterable
class ListField(models.TextField):
"""

Motivation: User would like to Retrieve aws instance metadata.
Solution:
The IP address 169.254.169.254
is a link-local address (and is valid only from the instance) aws gives us link with dedicated Restful API for Retrieving metadata of our running instance (Note that you are not billed for HTTP requests used to retrieve instance metadata and user data) . for Additional Documentation
Example:
//Request:
curl http://169.254.169.254/latest/meta-data/instance-id
//Response
ami-123abc
You able to get additional metadata labels of your instance using this link http://169.254.169.254/latest/meta-data/<metadata-field>
just choose the right tags:
Don't over complicate.
document.addEventListener('keydown', logKey);
function logKey(e) {
if (`${e.code}` == "ArrowRight") {
//code here
}
if (`${e.code}` == "ArrowLeft") {
//code here
}
if (`${e.code}` == "ArrowDown") {
//code here
}
if (`${e.code}` == "ArrowUp") {
//code here
}
}

Mac Users, let me save you the time:
I think I can illustrate this quite nicely. Since nextTick
is called at the end of the current operation, calling it recursively can end up blocking the event loop from continuing. setImmediate
solves this by firing in the check phase of the event loop, allowing event loop to continue normally.

¦ +-----------------------+
+--¦ close callbacks ¦
+-----------------------+
source: https://nodejs.org/en/docs/guides/event-loop-timers-and-nexttick/
Notice that the check phase is immediately after the poll phase. This is because the poll phase and I/O callbacks are the most likely places your calls to setImmediate
are going to run. So ideally most of those calls will actually be pretty immediate, just not as immediate as nextTick
which is checked after every operation and technically exists outside of the event loop.
Let's take a look at a little example of the difference between setImmediate
and process.nextTick
:
function step(iteration) {
if (iteration === 10) return;
setImmediate(() => {
console.log(`setImmediate iteration: ${iteration}`);
step(iteration + 1); // Recursive call from setImmediate handler.
});
process.nextTick(() => {
console.log(`nextTick iteration: ${iteration}`);
});
}
step(0);
Let's say we just ran this program and are stepping through the first iteration of the event loop. It will call into the step
function with iteration zero. It will then register two handlers, one for setImmediate
and one for process.nextTick
. We then recursively call this function from the setImmediate
handler which will run in the next check phase. The nextTick
handler will run at the end of the current operation interrupting the event loop, so even though it was registered second it will actually run first.
The order ends up being: nextTick
fires as current operation ends, next event loop begins, normal event loop phases execute, setImmediate
fires and recursively calls our step
function to start the process all over again. Current operation ends, nextTick
fires, etc.
The output of the above code would be:
nextTick iteration: 0
setImmediate iteration: 0
nextTick iteration: 1
setImmediate iteration: 1
nextTick iteration: 2
setImmediate iteration: 2
nextTick iteration: 3
setImmediate iteration: 3
nextTick iteration: 4
setImmediate iteration: 4
nextTick iteration: 5
setImmediate iteration: 5
nextTick iteration: 6
setImmediate iteration: 6
nextTick iteration: 7
setImmediate iteration: 7
nextTick iteration: 8
setImmediate iteration: 8
nextTick iteration: 9
setImmediate iteration: 9
Now let's move our recursive call to step
into our nextTick
handler instead of the setImmediate
.
function step(iteration) {
if (iteration === 10) return;
setImmediate(() => {
console.log(`setImmediate iteration: ${iteration}`);
});
process.nextTick(() => {
console.log(`nextTick iteration: ${iteration}`);
step(iteration + 1); // Recursive call from nextTick handler.
});
}
step(0);
Now that we have moved the recursive call to step
into the nextTick
handler things will behave in a different order. Our first iteration of the event loop runs and calls step
registering a setImmedaite
handler as well as a nextTick
handler. After the current operation ends our nextTick
handler fires which recursively calls step
and registers another setImmediate
handler as well as another nextTick
handler. Since a nextTick
handler fires after the current operation, registering a nextTick
handler within a nextTick
handler will cause the second handler to run immediately after the current handler operation finishes. The nextTick
handlers will keep firing, preventing the current event loop from ever continuing. We will get through all our nextTick
handlers before we see a single setImmediate
handler fire.
The output of the above code ends up being:
nextTick iteration: 0
nextTick iteration: 1
nextTick iteration: 2
nextTick iteration: 3
nextTick iteration: 4
nextTick iteration: 5
nextTick iteration: 6
nextTick iteration: 7
nextTick iteration: 8
nextTick iteration: 9
setImmediate iteration: 0
setImmediate iteration: 1
setImmediate iteration: 2
setImmediate iteration: 3
setImmediate iteration: 4
setImmediate iteration: 5
setImmediate iteration: 6
setImmediate iteration: 7
setImmediate iteration: 8
setImmediate iteration: 9
Note that had we not interrupted the recursive call and aborted it after 10 iterations then the nextTick
calls would keep recursing and never letting the event loop continue to the next phase. This is how nextTick
can become blocking when used recursively whereas setImmediate
will fire in the next event loop and setting another setImmediate
handler from within one won't interrupt the current event loop at all, allowing it to continue executing phases of the event loop as normal.
Hope that helps!
PS - I agree with other commenters that the names of the two functions could easily be swapped since nextTick
sounds like it's going to fire in the next event loop rather than the end of the current one, and the end of the current loop is more "immediate" than the beginning of the next loop. Oh well, that's what we get as an API matures and people come to depend on existing interfaces.

What you're trying to do sounds dangerous, as that's not the intended use of AUTO_INCREMENT
.
If you really want to find the lowest unused key value, don't use AUTO_INCREMENT
at all, and manage your keys manually. However, this is NOT a recommended practice.
Take a step back and ask "why you need to recycle key values?" Do unsigned INT
(or BIGINT
) not provide a large enough key space?
Are you really going to have more than 18,446,744,073,709,551,615
unique records over the course of your application's lifetime?
Yes, the constant CI_VERSION
will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php
For example,
echo CI_VERSION; // echoes something like 1.7.1
create a logfile in php, to do it you need to pass data on function and it will create log file for you.
function wh_log($log_msg)
{
$log_filename = "log";
if (!file_exists($log_filename))
{
// create directory/folder uploads.
mkdir($log_filename, 0777, true);
}
$log_file_data = $log_filename.'/log_' . date('d-M-Y') . '.log';
// if you don't add `FILE_APPEND`, the file will be erased each time you add a log
file_put_contents($log_file_data, $log_msg . "\n", FILE_APPEND);
}
// call to function
wh_log("this is my log message");

The framework "translate" it in ?Lenght when there is a mismatch in the parameter/route
If you're on Windows, you may find the config file my.ini
it in this directory
C:\ProgramData\MySQL\MySQL Server 5.7\
You open this file in a text editor and look for this section:
# The TCP/IP Port the MySQL Server will listen on
port=3306
Then you change the number of the port, save the file. Find the service MYSQL57 under Task Manager > Services and restart it.
ax.set_title('My Title\n', fontsize="15", color="red")
plt.imshow(myfile, origin="upper")
If you put '\n'
right after your title string, the plot is drawn just below the title. That might be a fast solution too.
I know the topic is a bit old and seems stale, but anyway I was able to use these options:
deploy:
resources:
limits:
cpus: '0.001'
memory: 50M
when using 3.7 version of docker-compose
What helped in my case, was using this command:
docker-compose --compatibility up
--compatibility
flag stands for (taken from the documentation):
If set, Compose will attempt to convert deploy keys in v3 files to their non-Swarm equivalent
Think it's great, that I don't have to revert my docker-compose file back to v2.
I wonder why no one added the alternative of using the function chr()
:
echo 'Hello World!' . chr(10);
or, more efficient if you're going to repeat it a million times:
define('C_NewLine', chr(10));
...
echo 'Hello World!' . C_NewLine;
This avoids the silly-looking notation of concatenating a single- and double-quoted string.
There are so many answers for this question here but it seems there is a bit of confusion about what's actually going on here.
Firstly, your premise
"href overrides ng-click in Angular.js"
is wrong. What is actually happening is that after your click, the click event is first handled by angular(defined by ng-click
directive in angular 1.x and click
in angular 2.x+) and then it continues to propagate(which eventually triggers the browser to navigate to the url defined with href
attribute).(See this for more about event propagation in javascript)
If you want to avoid this, then you should cancel the event propagation using the The Event interface's preventDefault()
method:
<a href="#" ng-click="$event.preventDefault();logout()" />
(This is pure javascript functionality and nothing to do with angular)
Now, this will already solve your problem but this is not the optimal solution. Angular, rightfully, promotes the MVC pattern. With this solution, your html template is mixed with the javascript logic. You should try to avoid this as much as possible and put your logic into your angular controller. So a better way would be
<a href="#" ng-click="logout($event)" />
And in your logout() method:
logout($event) {
$event.preventDefault();
...
}
Now the click event will not reach the browser, so it will not try to load the link pointed by href
. (However note that if the user right clicks on the link and directly opens the link, then there won't be a click event at all. Instead it will directly load the url pointed by the href
attribute.)
Regarding the comments about visited link color in the browsers. Again this has nothing to do with angular, if your href="..."
points to a visited url by your browser by default the link color will be different. This is controlled by CSS :visited Selector, you can modify your css to override this behaviour:
a {
color:pink;
}
PS1:
Some answers suggest to use:
<a href .../>
href
is an angular directive. When your template is processed by angular this will be converted to
<a href="" .../>
Those two ways are essentially the same.
Convert Double
to Float
public static Float convertToFloat(Double doubleValue) {
return doubleValue == null ? null : doubleValue.floatValue();
}
Convert double
to Float
public static Float convertToFloat(double doubleValue) {
return (float) doubleValue;
}
This is my solution
var error=0;
var test = [" ", " "];
if(test[0].match(/^\s*$/g)) {
$("#output").html("MATCH!");
error+=1;
} else {
$("#output").html("no_match");
}
its happen when you try to delete the same object and then again update the same object use this after delete
session.clear();
nothing
. This can be used to provide optional arguments.string s = &str1 + &str2;
using pointers. void f(const T& t); ... f(T(a, b, c));
, pointers cannot be used like that since you cannot take the address of a temporary.Bootstrap 3 with DataTables Example: Bootstrap Docs & DataTables Docs

Since the reduce
method has been removed from the built in function from Python3, don't forget to import the functools
in your code. Please look at the code snippet below.
import functools
my_list = [10,15,20,25,35]
sum_numbers = functools.reduce(lambda x ,y : x+y , my_list)
print(sum_numbers)
This also works in Rails 5.
If the migration was the most recent one you can remove the database column(s) that the migration added by doing:
rake db:rollback
then remove the migration file itself by running:
rails d migration WhateverYourMigrationWasNamed.rb
Extends : This is used to get attributes of a parent class into base class and may contain already defined methods that can be overridden in the child class.
Implements : This is used to implement an interface (parent class with functions signatures only but not their definitions) by defining it in the child class.
There is one special condition: "What if I want a new Interface to be the child of an existing interface?". In the above condition, the child interface extends the parent interface.
In Swift 5
Let's say if want to Receive Data from ViewControllerB to ViewControllerA
ViewControllerA (Receiver)
import UIKit
class ViewControllerA: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//MARK: - - - - - Code for Passing Data through Notification Observer - - - - -
// add observer in controller(s) where you want to receive data
NotificationCenter.default.addObserver(self, selector: #selector(self.methodOfReceivedNotification(notification:)), name: Notification.Name("NotificationIdentifier"), object: nil)
}
//MARK: - - - - - Method for receiving Data through Post Notificaiton - - - - -
@objc func methodOfReceivedNotification(notification: Notification) {
print("Value of notification : ", notification.object ?? "")
}
}
ViewControllerB (Sender)
import UIKit
class ViewControllerB: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//MARK: - - - - - Set data for Passing Data Post Notification - - - - -
let objToBeSent = "Test Message from Notification"
NotificationCenter.default.post(name: Notification.Name("NotificationIdentifier"), object: objToBeSent)
}
}
If you'd like to know what is the numeric version of FireFox you can use the following snippet:
var match = window.navigator.userAgent.match(/Firefox\/([0-9]+)\./);
var ver = match ? parseInt(match[1]) : 0;
Using the minus
operator was working but also it was taking more time to execute which was not acceptable.
I have a similar kind of requirement for data migration and I used the NOT IN
operator for that.
The modified query is :
select *
from A
where (emp_id,emp_name) not in
(select emp_id,emp_name from B)
union all
select * from B
where (emp_id,emp_name) not in
(select emp_id,emp_name from A);
This query executed fast. Also you can add any number of columns in the select query. Only catch is that both tables should have the exact same table structure for this to be executed.
# syntaxis:2.7
# solution for quadratic equation
# a*x**2 + b*x + c = 0
d = b**2-4*a*c # discriminant
if d < 0:
print 'No solutions'
elif d == 0:
x1 = -b / (2*a)
print 'The sole solution is',x1
else: # if d > 0
x1 = (-b + math.sqrt(d)) / (2*a)
x2 = (-b - math.sqrt(d)) / (2*a)
print 'Solutions are',x1,'and',x2
You can only do this to you own photos. Due to recent upgrades, Facebook has made this more difficult. To do this, go to the album page where the photo is that you want to link to. You should see thumbnail images of the photos in the album. Hold down the "Control" or "Command" key while clicking the photo that you wish to link to. A new browser tab will open with the picture you clicked. Under the picture there is a URL that you can send to others to share the photo. You might have to have the privacy settings for that album set so that anyone can see the photos in that album. If you don't the person who clicks the link may have to be signed in and also be your "friend."
Here is an example of one of my photos: http://www.facebook.com/photo.php?pid=43764341&l=0d8a526a64&id=25502298 -it's my cat.
Update:
The link below the photo no longer appears. Once you open the photo in a new tab you can right click the photo (Control+click for Mac users) and click "Copy Image URL" or similar and then share this link. Based on my tests the person who clicks the link doesn't need to use Facebook. The photo will load without the Facebook interface. Like this - http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/189088_867367406856_25502298_43764341_1304758_n.jpg
$CI =& get_instance();
if($CI->input->get('id'){
$id = $CI->input->get('id');
}
Yes, the solution is to use setTimeout, like this:
var delay = 10000;
var url = "https://stackoverflow.com";
var timeoutID = setTimeout(function() {
window.location.href = url;
}, delay);
note that the result was stored into timeoutID
. If, for whatever reason you need to cancel the order, you just need to call
clearTimeout(timeoutID);
You can use reflection.
Type typeOfMyObject = myObject.GetType();
PropertyInfo[] properties =typeOfMyObject.GetProperties();
if(isset($_GET['content'])){
$content = $_GET['content'];
$dir = $_GET['dir'];
header("Content-type:".$content);
@readfile($dir);
}
$directory = (file_exists("mydir/"))?"mydir/":die("file/directory doesn't exists");// checks directory if existing.
//the line above is just a one-line if statement (syntax: (conditon)?code here if true : code if false; )
if($handle = opendir($directory)){ //opens directory if existing.
while ($file = readdir($handle)) { //assign each file with link <a> tag with GET params
echo '<a target="_blank" href="?content=application/pdf&dir='.$directory.'">'.$file.'</a>';
}
}
if you click the link a new window will appear with the pdf file
This works well:
function test(el){
el.childNodes.item("child").style.display = "none";
}
If the argument of item() function is an integer, the function will treat it as an index. If the argument is a string, then the function searches for name or ID of element.
For a VARBINARY(MAX)
column, I had to use NVARCHAR(MAX)
:
cast(Content as nvarchar(max))
Or
CONVERT(NVARCHAR(MAX), Content, 0)
VARCHAR(MAX) didn't show the entire value
I just got done doing this exact thing in a project. The HTML side looked a bit like this:
<a href="[fullsize]" class="gallerypic" title="">
<img src="[thumbnail pic]" height="90" width="140" alt="[Gallery Photo]" class="pic" />
<span class="zoom-icon">
<img src="/images/misc/zoom.gif" width="32" height="32" alt="Zoom">
</span>
</a>
Then using CSS:
a.gallerypic{
width:140px;
text-decoration:none;
position:relative;
display:block;
border:1px solid #666;
padding:3px;
margin-right:5px;
float:left;
}
a.gallerypic span.zoom-icon{
visibility:hidden;
position:absolute;
left:40%;
top:35%;
filter:alpha(opacity=50);
-moz-opacity:0.5;
-khtml-opacity: 0.5;
opacity: 0.5;
}
a.gallerypic:hover span.zoom-icon{
visibility:visible;
}
I left a lot of the sample in there on the CSS so you can see how I decided to do the style. Note I lowered the opacity so you could see through the magnifying glass.
Hope this helps.
EDIT: To clarify for your example - you could ignore the visibility:hidden;
and kill the :hover
execution if you wanted, this was just the way I did it.

For me solution was to change the Resharper Unit Testing settings "Default platform architecture" to "x64"
open is only for another module for example: cocoa pods, or unit test, we can inherit or override
you can make use of the below code for sorting in descending order and storing to a dictionary:
listname = []
for key, value in sorted(dictionaryName.iteritems(), key=lambda (k,v): (v,k),reverse=True):
diction= {"value":value, "key":key}
listname.append(diction)
Explain only shows how the optimizer thinks the query will execute.
To show the real plan, you will need to run the sql once. Then use the same session run the following:
@yoursql
select * from table(dbms_xplan.display_cursor())
This way can show the real plan used during execution. There are several other ways in showing plan using dbms_xplan. You can Google with term "dbms_xplan".
You need to give the body
and the html
a height too. Otherwise, the body will only be as high as its contents (the single div), and 50% of that will be half the height of this div.

Do you mean tmux window? Ctrl + b + ,
if you have C-b as send prefix (it's by default)
Also C-b :rename-window <new name>
and tmux rename-window <new name>
work too.
As I know you can't rename pane
I know this is late, but for future reference, put the date format into a recognised format by using str_replace then your function will work. (replace the underscore with a dash)
//change the format to dashes instead of underscores, then get the timestamp
$date1 = strtotime(str_replace("_", "-",$date1));
$date2 = strtotime(str_replace("_", "-",$date2));
//compare the dates
if($date1 < $date2){
//convert the date back to underscore format if needed when printing it out.
echo '1 is small='.$date1.','.date('d_m_y',$date1);
}else{
echo '2 is small='.$date2.','.date('d_m_y',$date2);
}
The way I use is:
git submodule update --init --recursive
git submodule foreach --recursive git fetch
git submodule foreach git merge origin master
This is deprecated:
as.data.frame(my_table)
Instead use this package:
library("quanteda")
convert(my_table, to="data.frame")
The form
tag needs some attributes set:
action
: The URL that the form data is sent to on submit. Generate it with url_for
. It can be omitted if the same URL handles showing the form and processing the data.method="post"
: Submits the data as form data with the POST method. If not given, or explicitly set to get
, the data is submitted in the query string (request.args
) with the GET method instead.enctype="multipart/form-data"
: When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.The input
tag needs a name
parameter.
Add a view to handle the submitted data, which is in request.form
under the same key as the input's name
. Any file inputs will be in request.files
.
@app.route('/handle_data', methods=['POST'])
def handle_data():
projectpath = request.form['projectFilepath']
# your code
# return a response
Set the form's action
to that view's URL using url_for
:
<form action="{{ url_for('handle_data') }}" method="post">
<input type="text" name="projectFilepath">
<input type="submit">
</form>
not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
The native lib is expected in one of the following locations
/usr/java/packages/lib/amd64
/usr/lib64
/lib64
/lib
/usr/lib
and not in
tomcat/lib
The files in tomcat/lib
are all jar
file and are added by tomcat to the classpath
so that they are available to your application.
The native lib is needed by tomcat to perform better on the platform it is installed on and thus cannot be a jar
, for linux it could be a .so
file, for windows it could be a .dll
file.
Just download the native library for your platform and place it in the one of the locations tomcat is expecting it to be.
Note that you are not required to have this lib for development/test purposes. Tomcat runs just fine without it.
org.apache.catalina.startup.Catalina start INFO: Server startup in 2882 ms
EDIT
The output you are getting is very normal, it's just some logging outputs from tomcat, the line right above indicates that the server correctly started and is ready for operating.
If you are troubling with running your servlet then after the run on sever
command eclipse opens a browser window (embeded (default) or external, depends on your config). If nothing shows on the browser, then check the url bar of the browser to see whether your servlet was requested or not.
It should be something like that
http://localhost:8080/<your-context-name>/<your-servlet-name>
EDIT 2
Try to call your servlet using the following url
http://localhost:8080/com.filecounter/FileCounter
Also each web project has a web.xml, you can find it in your project under WebContent\WEB-INF
.
It is better to configure your servlets there using servlet-name
servlet-class
and url-mapping
. It could look like that:
<servlet>
<description></description>
<display-name>File counter - My first servlet</display-name>
<servlet-name>file_counter</servlet-name>
<servlet-class>com.filecounter.FileCounter</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>file_counter</servlet-name>
<url-pattern>/FileFounter</url-pattern>
</servlet-mapping>
In eclipse dynamic web project the default context name is the same as your project name.
http://localhost:8080/<your-context-name>/FileCounter
will work too.
you can change jquery-ui-1.10.4.custom.css as follows
.ui-widget
{
font-family: Lucida Grande,Lucida Sans,Arial,sans-serif;
font-size: 0.6em;
}
I don't think this question has been completely answered yet because all of the answers only give single match examples. The OP's question demonstrates the nuances of having 2 matches as well as a substring match which should not be reported because it is not a word/token.
To match multiple occurrences, one might do something like this:
iter = re.finditer(r"\bis\b", String)
indices = [m.start(0) for m in iter]
This would return a list of the two indices for the original string.
Besides all above solutions, check if you have the "id
" or any custom defined parameter in the DELETE
method is matching the route config.
public void Delete(int id)
{
//some code here
}
If you hit with repeated 405 errors better reset the method signature to default as above and try.
The route config by default will look for id
in the URL. So the parameter name id
is important here unless you change the route config under the App_Start
folder.
You may change the data type of the id
though.
For example the method below should work just fine:
public void Delete(string id)
{
//some code here
}
Note: Also ensure that you pass the data over the url not the data method that will carry the payload as body content.
DELETE http://{url}/{action}/{id}
Example:
DELETE http://localhost/item/1
Hope it helps.
Well, I'd expect it's this line that's throwing the exception:
var documentRow = _dsACL.Documents.First(o => o.ID == id)
First()
will throw an exception if it can't find any matching elements. Given that you're testing for null immediately afterwards, it sounds like you want FirstOrDefault()
, which returns the default value for the element type (which is null for reference types) if no matching items are found:
var documentRow = _dsACL.Documents.FirstOrDefault(o => o.ID == id)
Other options to consider in some situations are Single()
(when you believe there's exactly one matching element) and SingleOrDefault()
(when you believe there's exactly one or zero matching elements). I suspect that FirstOrDefault
is the best option in this particular case, but it's worth knowing about the others anyway.
On the other hand, it looks like you might actually be better off with a join here in the first place. If you didn't care that it would do all matches (rather than just the first) you could use:
var query = from target in _lstAcl.Documents
join source in _dsAcl.Document
where source.ID.ToString() equals target.ID
select new { source, target };
foreach (var pair in query)
{
target.Read = source.Read;
target.ReadRule = source.ReadRule;
// etc
}
That's simpler and more efficient IMO.
Even if you do decide to keep the loop, I have a couple of suggestions:
if
. You don't need it, as if Count is zero the for loop body will never executeUse exclusive upper bounds in for loops - they're more idiomatic in C#:
for (i = 0; i < _lstAcl.Documents.Count; i++)
Eliminate common subexpressions:
var target = _lstAcl.Documents[i];
// Now use target for the rest of the loop body
Where possible use foreach
instead of for
to start with:
foreach (var target in _lstAcl.Documents)
If you will invoke the script with source
, you can use return <x>
where <x>
will be the script exit status (use a non-zero value for error or false). But if you invoke an executable script (i.e., directly with its filename), the return statement will result in a complain (error message "return: can only `return' from a function or sourced script").
If exit <x>
is used instead, when the script is invoked with source
, it will result in exiting the shell that started the script, but an executable script will just terminate, as expected.
To handle either case in the same script, you can use
return <x> 2> /dev/null || exit <x>
This will handle whichever invocation may be suitable. That is assuming you will use this statement at the script's top level. I would advise against directly exiting the script from within a function.
Note: <x>
is supposed to be just a number.
Try executing the following query:
SELECT DATE_ADD(DATE_ADD(LAST_DAY(CURRENT_DATE-INTERVAL 1 DAY),INTERVAL 1 DAY),INTERVAL -1 MONTH)
It is a bit time consuming converting your markup and CSS to React-PDF's format, but it is easy to understand. Exporting a PDF and from it is fairly straightforward.
To allow a user to download a PDF generated by react-PDF, use their on the fly rendering, which provides a customizable download link. When clicked, the site renders and downloads the PDF for the user.
Here's their REPL which will familiarize you with the markup and styling required. They have a download link for the PDF too, but they don't show the code for that here.
hey there for anyone who might be looking for solution like this.. i had issue with scaling inside WebView so best way to do is in your java.class where you set all for webView put this two line of code: (webViewSearch is name of my webView -->webViewSearch = (WebView) findViewById(R.id.id_webview_search);)
// force WebView to show content not zoomed---------------------------------------------------------
webViewSearch.getSettings().setLoadWithOverviewMode(true);
webViewSearch.getSettings().setUseWideViewPort(true);
If you want it to "stick" to the bottom, regardless of the height of container, then absolute positioning is the way to go. Of course, if the copyright element is the last in the container it'll always be at the bottom anyway.
Can you expand on your question? Explain exactly what you're trying to do (and why you don't want to use absolute positioning)?
You have to add a connectionString
within your Web.config file as
<connectionStrings>
<add name="ASPNETConnectionString" connectionString="Data Source=SONU\SA;Initial Catalog=ASPNET;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
Then Write your SQL connection string as below:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
public partial class WebPages_database : System.Web.UI.Page
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ASPNETConnectionString"].ToString());
SqlDataAdapter da;
DataSet ds;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnAdmnNumber_Click(object sender, EventArgs e)
{
string qry = "select * from Table";
da = new SqlDataAdapter(qry, con);
ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
}
}

You can subtract the time zone difference from now.
final Calendar calendar = Calendar.getInstance();
final int utcOffset = calendar.get(Calendar.ZONE_OFFSET) + calendar.get(Calendar.DST_OFFSET);
final long tempDate = new Date().getTime();
return new Date(tempDate - utcOffset);

In express v3.0,
/* No longer valid */
var app = express.createServer();
app.listen();
console.log('Server running on %s', app.address().port);
no longer works! For Express v3.0, you should create an app and a server this way:
var express = require('express');
var http = require('http');
var app = express();
var server = http.createServer(app);
app.get('/', function(req, res) {
res.send("Hello World!");
});
server.listen(3000);
console.log('Express server started on port %s', server.address().port);
I ran in to this issue myself and wanted to document the new syntax. This and other changes in Express v3.0 are visible at https://github.com/visionmedia/express/wiki/Migrating-from-2.x-to-3.x
You can just simply add the following code;
<a class="btn btn-primary" href="http://localhost:8080/Home" role="button">Home Page</a>
There is a simple way.
You create an iframe which have for source something like "http://your-domain.com/index.php?url=http://the-site-you-want-to-get.com/unicorn
Then, you just get this url with $_GET
and display the contents with file_get_contents($_GET['url']);
You will obtain an iframe which has a domain same than yours, then you will be able to use the $("iframe").contents().find("body")
to manipulate the content.
You can change the highlight color in several ways.
Change the selectionStyle property of your cell. If you change it to UITableViewCellSelectionStyleGray
, it will be gray.
Change the selectedBackgroundView
property. Actually what creates the blue gradient is a view. You can create a view and draw what ever you like, and use the view as the background of your table view cells.
Try this one.
#/bin/bash
testpid="abc,def,ghij"
count=`echo $testpid | grep -o ',' | wc -l` # this is not a good way
count=`expr $count + 1`
while [ $count -gt 0 ] ; do
echo $testpid | cut -d ',' -f $i
count=`expr $count - 1 `
done
You should definitely use this one.
from os.path import exists
if exists("file") == True:

elif exists("file") == False:
print "File doesn't exist."
Agreeing with TrueWill's comment on a separate answer, the best way I've seen to use system.web.http on a .NET 4 targeted project under current Visual Studio is Install-Package Microsoft.AspNet.WebApi.Client -Version 4.0.30506
As far as I know, the order of the repositories in your pom.xml will also decide the order of the repository access.
As for configuring repositories in settings.xml, I've read that the order of repositories is interestingly enough the inverse order of how the repositories will be accessed.
Here a post where someone explains this curiosity:
http://community.jboss.org/message/576851
Why use the canvas to resize images? Modern browsers all use bicubic interpolation — the same process used by Photoshop (if you're doing it right) — and they do it faster than the canvas process. Just specify the image size you want (use only one dimension, height or width, to resize proportionally).
This is supported by most browsers, including later versions of IE. Earlier versions may require browser-specific CSS.
A simple function (using jQuery) to resize an image would be like this:
function resizeImage(img, percentage) {
var coeff = percentage/100,
width = $(img).width(),
height = $(img).height();
return {"width": width*coeff, "height": height*coeff}
}
Then just use the returned value to resize the image in one or both dimensions.
Obviously there are different refinements you could make, but this gets the job done.
Paste the following code into the console of this page and watch what happens to the gravatars:
function resizeImage(img, percentage) {
var coeff = percentage/100,
width = $(img).width(),
height = $(img).height();
return {"width": width*coeff, "height": height*coeff}
}
$('.user-gravatar32 img').each(function(){
var newDimensions = resizeImage( this, 150);
this.style.width = newDimensions.width + "px";
this.style.height = newDimensions.height + "px";
});

Nodejs is a scripting language (like Python or Ruby, and unlike PHP or C++). To run your code, you need to enter a command in the terminal / shell / command prompt. Look for an application shortcut in your operating system by one of those names.
The command to run in the terminal will be
node server.js
But you will first need to browse in the terminal to the same folder as the file server.js
. The syntax for using the terminal varies by operating system, look for its documentation.
wait() works fine for me. The subprocesses p1, p2 and p3 are executed at the same. Therefore, all processes are done after 3 seconds.
import subprocess
processes = []
p1 = subprocess.Popen("sleep 3", stdout=subprocess.PIPE, shell=True)
p2 = subprocess.Popen("sleep 3", stdout=subprocess.PIPE, shell=True)
p3 = subprocess.Popen("sleep 3", stdout=subprocess.PIPE, shell=True)
processes.append(p1)
processes.append(p2)
processes.append(p3)
for p in processes:
if p.wait() != 0:
print("There was an error")
print("all processed finished")
An abstract class is like the normal class it contains variables it contains protected variables functions it contains constructor only one thing is different it contains abstract method.
The abstract method means an empty method without definition so only one difference in abstract class we can not create an object of abstract class
Abstract must contains the abstract method and those methods must be defined in its inheriting class.
Neither is better than the other, they do exactly the same thing. However, using .encode()
and .decode()
is the more common way to do it. It is also compatible with Python 2.
You basically have two options.
If you use the same user on both machines you need to copy the .pub key to your PC, so GitHub knows that you are the same user.
If you have created a new .pub file for your PC and want to treat the machines as different users, you need to register the new .pub file on the GitHub website.
If this still doesn't work it might be because ssh is not configured correctly and that ssh fail to find the location of your keys. Try
ssh -vv [email protected]
To get more information why SSH fails.
I converted the VB code in the blog post linked by xsl to C# and modified it a bit:
public static bool TryGetRegisteredApplication(
string extension, out string registeredApp)
{
string extensionId = GetClassesRootKeyDefaultValue(extension);
if (extensionId == null)
{
registeredApp = null;
return false;
}
string openCommand = GetClassesRootKeyDefaultValue(
Path.Combine(new[] {extensionId, "shell", "open", "command"}));
if (openCommand == null)
{
registeredApp = null;
return false;
}
registeredApp = openCommand
.Replace("%1", string.Empty)
.Replace("\"", string.Empty)
.Trim();
return true;
}
private static string GetClassesRootKeyDefaultValue(string keyPath)
{
using (var key = Registry.ClassesRoot.OpenSubKey(keyPath))
{
if (key == null)
{
return null;
}
var defaultValue = key.GetValue(null);
if (defaultValue == null)
{
return null;
}
return defaultValue.ToString();
}
}
EDIT - this is unreliable. See Finding the default application for opening a particular file type on Windows.
This example is from the MSDN page on ResourceManager.GetString():
// Create a resource manager to retrieve resources.
ResourceManager rm = new ResourceManager("items", Assembly.GetExecutingAssembly());
// Retrieve the value of the string resource named "welcome".
// The resource manager will retrieve the value of the
// localized resource using the caller's current culture setting.
String str = rm.GetString("welcome");

fetch
will download any changes from the remote* branch, updating your repository data, but leaving your local* branch unchanged.
pull
will perform a fetch
and additionally merge
the changes into your local branch.
What's the difference? pull
updates you local branch with changes from the pulled branch. A fetch
does not advance your local branch.
Given the following history:
C---D---E local / A---B---F---G remote
merge
joins two development histories together. It does this by replaying the changes that occurred on your local branch after it diverged on top of the remote branch, and record the result in a new commit. This operation preserves the ancestry of each commit.
The effect of a merge
will be:
C---D---E local / \ A---B---F---G---H remote
rebase
will take commits that exist in your local branch and re-apply them on top of the remote branch. This operation re-writes the ancestors of your local commits.
The effect of a rebase
will be:
C'--D'--E' local / A---B---F---G remote
What's the difference? A merge
does not change the ancestry of commits. A rebase
rewrites the ancestry of your local commits.
*
This explanation assumes that the current branch is a local branch, and that the branch specified as the argument to fetch
, pull
, merge
, or rebase
is a remote branch. This is the usual case. pull
, for example, will download any changes from the specified branch, update your repository and merge
the changes into the current branch.
Another variation on the already proposed answers without jQuery.
Object.values(document.getElementById('mySelect').options).forEach(option => alert(option))
If you want to read the whole file into a variable:
#!/bin/bash
value=`cat sources.xml`
echo $value
If you want to read it line-by-line:
while read line; do
echo $line
done < file.txt
You should set responseType: ResponseContentType.Blob
in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.
Here is an working example:
Create image.service.ts
and put following code:
Angular 4:
getImage(imageUrl: string): Observable<File> {
return this.http
.get(imageUrl, { responseType: ResponseContentType.Blob })
.map((res: Response) => res.blob());
}
Angular 5+:
getImage(imageUrl: string): Observable<Blob> {
return this.httpClient.get(imageUrl, { responseType: 'blob' });
}
Important: Since Angular 5+ you should use the new HttpClient
.
The new HttpClient
returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'
. Read more about that here.
Now you need to create some function in your image.component.ts
to get image and show it in html.
For creating an image from Blob you need to use JavaScript's FileReader
.
Here is function which creates new FileReader
and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:
imageToShow: any;
createImageFromBlob(image: Blob) {
let reader = new FileReader();
reader.addEventListener("load", () => {
this.imageToShow = reader.result;
}, false);
if (image) {
reader.readAsDataURL(image);
}
}
Now you should use your created ImageService
to get image from api. You should to subscribe to data and give this data to createImageFromBlob
-function. Here is an example function:
getImageFromService() {
this.isImageLoading = true;
this.imageService.getImage(yourImageUrl).subscribe(data => {
this.createImageFromBlob(data);
this.isImageLoading = false;
}, error => {
this.isImageLoading = false;
console.log(error);
});
}
Now you can use your imageToShow
-variable in HTML template like this:
<img [src]="imageToShow"
alt="Place image title"
*ngIf="!isImageLoading; else noImageFound">
<ng-template #noImageFound>
<img src="fallbackImage.png" alt="Fallbackimage">
</ng-template>
I hope this description is clear to understand and you can use it in your project.
See the working example for Angular 5+ here.
you can also go for this.... this will only show the HTML section once javascript has loaded.
<!-- Adds the hidden style and removes it when javascript has loaded -->
<style type="text/css">
.hideAll {
visibility:hidden;
}
</style>
<script type="text/javascript">
$(window).load(function () {
$("#tabs").removeClass("hideAll");
});
</script>
<div id="tabs" class="hideAll">
##Content##
</div>
The accepted answer is correct as asked, below answers the opposite question of developing Android on VS Code.
Extensions
Ultimately you can automate building and running your app on a device emulator by adding the function below to your $PATH
and running runDebugApp <module> <start activity>
from the integrated terminal:
# run android app
# usage runDebugApp [module] [fully qualified start activity com.package/com.package.MainActivity]
function runDebugApp(){
./gradlew -offline :"$1":installDebug && adb shell am start "$2" && adb logcat -d > logcat.log
}
You can finish the Acivity and recreate it afterwards in this way your activity will be created again and all the views will be created with the new theme.
$(".testClick").click(function () {
var value = $(this).attr("href");
alert(value );
});
When you use $(".className") you are getting the set of all elements that have that class. Then when you call attr it simply returns the value of the first item in the collection.
From the description of material design specs:
Grid Lists are an alternative to standard list views. Grid lists are distinct from grids used for layouts and other visual presentations.
If you are looking for a much lightweight Grid component library, I'm using React-Flexbox-Grid, the implementation of flexboxgrid.css
in React.
On top of that, React-Flexbox-Grid played nicely with both material-ui, and react-toolbox (the alternative material design implementation).
The original question is about Bootstrap 3 and that supports IE8 and 9 so Flexbox would be the best option but it's not part of my answer due the lack of support, see http://caniuse.com/#feat=flexbox and toggle the IE box. Pretty bad, eh?
1. Display-table: You can muck around with turning the row into a display:table and the col- into display:table-cell. It works buuuut the limitations of tables are there, among those limitations are the push and pull and offsets won't work. Plus, I don't know where you're using this -- at what breakpoint. You should make the image full width and wrap it inside another container to put the padding on there. Also, you need to figure out the design on mobile, this is for 768px and up. When I use this, I redeclare the sizes and sometimes I stick importants on them because tables take on the width of the content inside them so having the widths declared again helps this. You will need to play around. I also use a script but you have to change the less files to use it or it won't work responsively.

This is very old post but if anyone ran into similar problem and need quick answer:

Another option may be this John Resig remove method. can better fit what you need. if you know the index in the array.
DisplayMetrics dm = getResources().getDisplayMetrics();
float fwidth = dm.density * dm.widthPixels;
float fheight = dm.density * dm.heightPixels;
If getSize
gets you an error due to your minSDKVersion and you don't want to use deprecated methods (getWidth
& getHeight
), the getMetrics
solution was originally posted on 2011 by Balaji.K... And Nik added a comment explaining getDisplayMetrics
also considers the status bar size.
Some other comments refer to multiply by the scale (density) in order to get the precise float value of the dimensions. Tested in Android v2.2 (API 8) and v4.0 with good results and no errors/warnings.

PHP allows "hinting" where you supply a class to specify an object. According to the PHP manual, "Type Hints can only be of the object and array (since PHP 5.1) type. Traditional type hinting with int and string isn't supported." The error is confusing because of your choice of "string" - put "myClass" in its place and the error will read differently: "Argument 1 passed to phpwtf() must be an instance of myClass, string given"
Been using this in production for some time now without any complaints (May take some tweaking to look right on your site.. for instance, subtracting the width of a sidebar, etc)

$("#jqgrid").setGridWidth($(window).width());
}).trigger('resize');
