I found that this works across the board:
<a href="https://www.google.com/maps/place/1+Fake+Street,+City+Province/State>Get Directions</a>
For desktops/laptops the user has to click Directions when that map loads, but from my testing all mobile devices will load that link in the Google Maps app without difficulty.
In cordova 3.3.1-0.1.2 the expected behavior is not working right.
in
http://cordova.apache.org/docs/en/3.3.0/config_ref_images.md.html#Icons%20and%20Splash%20Screens
it clearly states you're suppose to put them into your main www folder in a folder called res and icons that follow a particular naming convention instead of the original customizable config.xml specified way (in which you point to a file of your choosing, which was/is much better). it should take then from there for each platform and put them into the platforms/?android?/res/drawable-?dpi/icon.png but it does no such correct behavior at this time... bug.
so I guess we have to manually put them there for each platform. it would of course need to remove that from duplicating it into the www folder again. for me I had to totally replace the contents in the main www folder anyway because it simply didn't work with even hello world without hacking a redirect index.html to find some weird random folder there. Putting the res folder beside www makes the most sense but what ever it seems to be for me caused by this series of cascading and confusing design choices/flaws.
Alternatively you could use a for
loop as shown in the Groovy Docs:
def map = ['a':1, 'b':2, 'c':3]
for ( e in map ) {
print "key = ${e.key}, value = ${e.value}"
}
/*
Result:
key = a, value = 1
key = b, value = 2
key = c, value = 3
*/
One benefit of using a for
loop as opposed to an each
closure is easier debugging, as you cannot hit a break point inside an each
closure (when using Netbeans).
Try something like this:
yourControl.DataSource = countryInstance.Cities;
And if you are using WebForms you will need to add this line:
yourControl.DataBind();
As far as I know, there are 2 standard ways you can do that.
1. @Input
Whenever the data in the parent changes, the child gets notified about this in the ngOnChanges method. The child can act on it. This is the standard way of interacting with a child.
Parent-Component
public inputToChild: Object;
Parent-HTML
<child [data]="inputToChild"> </child>
Child-Component: @Input() data;
ngOnChanges(changes: { [property: string]: SimpleChange }){
// Extract changes to the input property by its name
let change: SimpleChange = changes['data'];
// Whenever the data in the parent changes, this method gets triggered. You
// can act on the changes here. You will have both the previous value and the
// current value here.
}
Creating a service and using an observable in the shared service. The child subscribes to it and whenever there is a change, the child will be notified. This is also a popular method. When you want to send something other than the data you pass as the input, this can be used.
SharedService
subject: Subject<Object>;
Parent-Component
constructor(sharedService: SharedService)
this.sharedService.subject.next(data);
Child-Component
constructor(sharedService: SharedService)
this.sharedService.subject.subscribe((data)=>{
// Whenever the parent emits using the next method, you can receive the data
in here and act on it.})
Try linux command chsh
.
The detailed command is chsh -s /bin/bash
.
It will prompt you to enter your password.
Your default login shell is /bin/bash
now. You must log out and log back in to see this change.
The following is quoted from man page:
The chsh command changes the user login shell. This determines the name of the users initial login command. A normal user may only change the login shell for her own account, the superuser may change the login shell for any account
This command will change the default login shell permanently.
Note: If your user account is remote such as on Kerberos authentication (e.g. Enterprise RHEL) then you will not be able to use chsh
.
Sometimes, even though it gives you this error, the breakpoint
still gets hit, so just ignore the error. This happens fairly often in the Views
of an MVC web app
.
Assuming you have access to servlet as below
http://localhost:8080/myapp/download?id=7
I need to create a servlet and register it to web.xml
web.xml
<servlet>
<servlet-name>DownloadServlet</servlet-name>
<servlet-class>com.myapp.servlet.DownloadServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DownloadServlet</servlet-name>
<url-pattern>/download</url-pattern>
</servlet-mapping>
DownloadServlet.java
public class DownloadServlet extends HttpServlet {
protected void doGet( HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String id = request.getParameter("id");
String fileName = "";
String fileType = "";
// Find this file id in database to get file name, and file type
// You must tell the browser the file type you are going to send
// for example application/pdf, text/plain, text/html, image/jpg
response.setContentType(fileType);
// Make sure to show the download dialog
response.setHeader("Content-disposition","attachment; filename=yourcustomfilename.pdf");
// Assume file name is retrieved from database
// For example D:\\file\\test.pdf
File my_file = new File(fileName);
// This should send the file to browser
OutputStream out = response.getOutputStream();
FileInputStream in = new FileInputStream(my_file);
byte[] buffer = new byte[4096];
int length;
while ((length = in.read(buffer)) > 0){
out.write(buffer, 0, length);
}
in.close();
out.flush();
}
}
If you already have the xml, and comes more than one attribute, you can handle it as follows:
String output = "<ciudads><ciudad><idCiudad>1</idCiudad>
<nomCiudad>BOGOTA</nomCiudad></ciudad><ciudad><idCiudad>6</idCiudad>
<nomCiudad>Pereira</nomCiudad></ciudads>";
DocumentBuilder db = DocumentBuilderFactory.newInstance()
.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(output));
Document doc = db.parse(is);
NodeList nodes = ((org.w3c.dom.Document) doc)
.getElementsByTagName("ciudad");
for (int i = 0; i < nodes.getLength(); i++) {
Ciudad ciudad = new Ciudad();
Element element = (Element) nodes.item(i);
NodeList name = element.getElementsByTagName("idCiudad");
Element element2 = (Element) name.item(0);
ciudad.setIdCiudad(Integer
.valueOf(getCharacterDataFromElement(element2)));
NodeList title = element.getElementsByTagName("nomCiudad");
element2 = (Element) title.item(0);
ciudad.setNombre(getCharacterDataFromElement(element2));
ciudades.getPartnerAccount().add(ciudad);
}
}
for (Ciudad ciudad1 : ciudades.getPartnerAccount()) {
System.out.println(ciudad1.getIdCiudad());
System.out.println(ciudad1.getNombre());
}
the method getCharacterDataFromElement is
public static String getCharacterDataFromElement(Element e) {
Node child = e.getFirstChild();
if (child instanceof CharacterData) {
CharacterData cd = (CharacterData) child;
return cd.getData();
}
return "";
}
again this is JS :) this still works ....
var linkToClick = document.getElementById('something');
linkToClick.click();
<Link id="something" to={/somewhaere}> the link </Link>
You can do this using two approaches:
Using Shared Preferences
Using Application class
Example:
class SessionManager extends Application{
String sessionKey;
setSessionKey(String key){
this.sessionKey=key;
}
String getSessisonKey(){
return this.sessionKey;
}
}
You can use above class to implement login in your MainActivity as below. Code will look something like this:
@override
public void onCreate (Bundle savedInstanceState){
// you will this key when first time login is successful.
SessionManager session= (SessionManager)getApplicationContext();
String key=getSessisonKey.getKey();
//Use this key to identify whether session is alive or not.
}
This method will work for temporary storage. You really do not any idea when operating system is gonna kill the application, because of low memory. When your application is in background and user is navigating through other application which demands more memory to run, then your application will be killed since operating system given more priority to foreground processes than background. Hence your application object will be null before user logs out. Hence for this I recommend to use second method Specified above.
Using shared preferences.
String MYPREF="com.your.application.session"
SharedPreferences pref= context.getSharedPreferences(MyPREF,MODE_PRIVATE);
//Insert key as below:
Editot editor= pref.edit();
editor.putString("key","value");
editor.commit();
//Get key as below.
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
String key= getResources().getString("key");
DateTime.Now.ToString("h:mm tt") DateTime.Now.ToString("MM/dd/yyyy")
Here are some common format strings
First, make sure you have Tkinter module installed.
sudo apt-get install python-tk
In python 2 the package name is Tkinter not tkinter.
from Tkinter import *

Talking about efficiency:
document.getElementById( 'elemtId' ).style.display = 'none';
What jQuery does with its .show()
and .hide()
methods is, that it remembers the last state of an element. That can come in handy sometimes, but since you asked about efficiency that doesn't matter here.
I took the answer above by @sbgoran and modified it for my case same as the question needed, to treat arrays as sets (i.e. order is not important for diff)
const deepDiffMapper = function () {
return {
VALUE_CREATED: "created",
VALUE_UPDATED: "updated",
VALUE_DELETED: "deleted",
VALUE_UNCHANGED: "unchanged",
map: function(obj1: any, obj2: any) {
if (this.isFunction(obj1) || this.isFunction(obj2)) {
throw "Invalid argument. Function given, object expected.";
}
if (this.isValue(obj1) || this.isValue(obj2)) {
return {
type: this.compareValues(obj1, obj2),
data: obj2 === undefined ? obj1 : obj2
};
}
if (this.isArray(obj1) || this.isArray(obj2)) {
return {
type: this.compareArrays(obj1, obj2),
data: this.getArrayDiffData(obj1, obj2)
};
}
const diff: any = {};
for (const key in obj1) {
if (this.isFunction(obj1[key])) {
continue;
}
let value2 = undefined;
if (obj2[key] !== undefined) {
value2 = obj2[key];
}
diff[key] = this.map(obj1[key], value2);
}
for (const key in obj2) {
if (this.isFunction(obj2[key]) || diff[key] !== undefined) {
continue;
}
diff[key] = this.map(undefined, obj2[key]);
}
return diff;
},
getArrayDiffData: function(arr1: Array<any>, arr2: Array<any>) {
const set1 = new Set(arr1);
const set2 = new Set(arr2);
if (arr1 === undefined || arr2 === undefined) {
return arr1 === undefined ? arr1 : arr2;
}
const deleted = [...arr1].filter(x => !set2.has(x));
const added = [...arr2].filter(x => !set1.has(x));
return {
added, deleted
};
},
compareArrays: function(arr1: Array<any>, arr2: Array<any>) {
const set1 = new Set(arr1);
const set2 = new Set(arr2);
if (_.isEqual(_.sortBy(arr1), _.sortBy(arr2))) {
return this.VALUE_UNCHANGED;
}
if (arr1 === undefined) {
return this.VALUE_CREATED;
}
if (arr2 === undefined) {
return this.VALUE_DELETED;
}
return this.VALUE_UPDATED;
},
compareValues: function (value1: any, value2: any) {
if (value1 === value2) {
return this.VALUE_UNCHANGED;
}
if (this.isDate(value1) && this.isDate(value2) && value1.getTime() === value2.getTime()) {
return this.VALUE_UNCHANGED;
}
if (value1 === undefined) {
return this.VALUE_CREATED;
}
if (value2 === undefined) {
return this.VALUE_DELETED;
}
return this.VALUE_UPDATED;
},
isFunction: function (x: any) {
return Object.prototype.toString.call(x) === "[object Function]";
},
isArray: function (x: any) {
return Object.prototype.toString.call(x) === "[object Array]";
},
isDate: function (x: any) {
return Object.prototype.toString.call(x) === "[object Date]";
},
isObject: function (x: any) {
return Object.prototype.toString.call(x) === "[object Object]";
},
isValue: function (x: any) {
return !this.isObject(x) && !this.isArray(x);
}
};
}();
This works for me.
import React, { useEffect } from 'react';
useEffect(() => {
const body = document.querySelector('#root');
body.scrollIntoView({
behavior: 'smooth'
}, 500)
}, []);
If the string is from a trusted source, you could use eval
then JSON.stringify
the result. Like this:
var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }";
var json = JSON.stringify(eval("(" + str + ")"));
Note that when you eval
an object literal, it has to be wrapped in parentheses, otherwise the braces are parsed as a block instead of an object.
I also agree with the comments under the question that it would be much better to just encode the object in valid JSON to begin with and avoid having to parse, encode, then presumably parse it again. HTML supports single-quoted attributes (just be sure to HTML-encode any single quotes inside strings).
Sure:
try {
throw new Exception('Something bad');
} catch (Exception $e) {
// Do nothing
}
You might want to go have a read of the PHP documentation on Exceptions.
Omit row if either of two specific columns contain <NA>
.
DF[!is.na(DF$x)&!is.na(DF$z),]
In the nav go View => Layout => Columns:2
(alt+shift+2
) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py
)
It appears you can also reopen the file using the command File -> New View into File
which will open the current file in a new tab
None of the solutions worked for me as of today. My situation was that I got my Android studio updated. The most popular thing to replace the tools folder with the latest one wouldn't work for me. Infact is not required in some cases.
npm update -g cordova
did the trick for me.
Then I removed the platform and added it again.
ionic platform remove android
ionic platform add android
This works for me in Ionic. I am surecordova platform remove/add android
will do the same stuff. Not tested though.
Working again !
Well if you want to return your array from a function you must make sure that the values are not stored on the stack as they will be gone when you leave the function.
So either make your array static or allocate the memory (or pass it in but your initial attempt is with a void parameter). For your method I would define it like this:
int *gnabber(){
static int foo[] = {1,2,3}
return foo;
}
As Tmdean correctly pointed out you can use the Mid()
function. The MSDN Library also has a great reference section on VBScript which you can find here:
Temporarily disable constraints on a table T-SQL, SQL Server

The problem is that '_' underscores are not valid in header attribute. If removing the underscore is not an option you can add to the server block:
underscores_in_headers on;
This is basically a copy and paste from @kishorer747 comment on @Fleshgrinder answer, and solution is from: https://serverfault.com/questions/586970/nginx-is-not-forwarding-a-header-value-when-using-proxy-pass/586997#586997
I added it here as in my case the application behind nginx was working perfectly fine, but as soon ngix was between my flask app and the client, my flask app would not see the headers any longer. It was kind of time consuming to debug.
Applying the Observer Pattern with delegates and events in c# is named "Event Pattern" according to MSDN which is a slight variation.
In this Article you will find well structured examples of how to apply the pattern in c# both the classic way and using delegates and events.
Exploring the Observer Design Pattern
public class Stock
{
//declare a delegate for the event
public delegate void AskPriceChangedHandler(object sender,
AskPriceChangedEventArgs e);
//declare the event using the delegate
public event AskPriceChangedHandler AskPriceChanged;
//instance variable for ask price
object _askPrice;
//property for ask price
public object AskPrice
{
set
{
//set the instance variable
_askPrice = value;
//fire the event
OnAskPriceChanged();
}
}//AskPrice property
//method to fire event delegate with proper name
protected void OnAskPriceChanged()
{
AskPriceChanged(this, new AskPriceChangedEventArgs(_askPrice));
}//AskPriceChanged
}//Stock class
//specialized event class for the askpricechanged event
public class AskPriceChangedEventArgs : EventArgs
{
//instance variable to store the ask price
private object _askPrice;
//constructor that sets askprice
public AskPriceChangedEventArgs(object askPrice) { _askPrice = askPrice; }
//public property for the ask price
public object AskPrice { get { return _askPrice; } }
}//AskPriceChangedEventArgs
While LIKE
is suitable for this case, a more general purpose solution is to use instr
, which doesn't require characters in the search string to be escaped. Note: instr
is available starting from Sqlite 3.7.15.
SELECT *
FROM TABLE
WHERE instr(column, 'cats') > 0;
Also, keep in mind that LIKE
is case-insensitive, whereas instr
is case-sensitive.
The Write-host work fine.
$Filesize = (Get-Item $filepath).length;
Write-Host "FileSize= $filesize";
I like the Aptana Browser Preview windo for this.
You can get it from their update site: http://download.aptana.org/tools/studio/plugin/update/studio/
After you install the Aptana plugin, open an Aptana project and there should be an option under help to install aptana features. under other you will find a Firefox/XUL browser. There may be a more direct way to install the XUL plugin, but the above procedure works.
This Problem is because of Path so you need to build the path using following Steps
Goto project ----->Right Click on Project Name ---->properties ---->click on Than Java Build Path option than ---> click Android 4.2.2---->Ok
Adding some understanding.
By Euclidean definition the mod result must be always positive.
Ex:
int n = 5;
int x = -3;
int mod(int n, int x)
{
return ((n%x)+x)%x;
}
Output:
-1
The reason the code isn't working is because lastrow is measured from whatever sheet is currently active, and "A:A500" (or other number) is not a valid range reference.
Private Sub CommandButton1_Click()
Dim lastrow As Long
lastrow = Sheets("Summary Info").Range("A65536").End(xlUp).Row ' or + 1
Range("A3:E3").Copy Destination:=Sheets("Summary Info").Range("A" & lastrow)
End Sub
As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with
<html>
<head>
<title>runthis</title>
<script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$(document).ready( function() {
var x = $("#foo").html();
alert( typeof(x) );
});
</script>
</head>
<body>
<div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
</body>
</html>
The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.
edit: Don't pass a string as the parameter data to .post() but an object, like
var data = {
id: currid,
html: div_html
};
$.post("http://...", data, ...);
jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().
var data = 'id='+ escape(currid) +'&html='+ escape(div_html);
To perform this operation see the next images:
and next step is add *.mdf file,
very important, the .mdf file must be located in C:......\MSSQL12.SQLEXPRESS\MSSQL\DATA
Now remove the log file
From WWDC 2015 there is a session on Implementing UI Designs in Interface Builder. Around the 32min mark he says that you always want to make your @IBOutlet
strong.
The xmlhttp request method is not valid for the files on local disk because the browser security does not allow us to do so.But we can override the browser security by creating a shortcut->right click->properties In target "... browser location path.exe" append --allow-file-access-from-files.This is tested on chrome,however care should be taken that all browser windows should be closed and the code should be run from the browser opened via this shortcut.
If Your Window pc, you may try this, it's also for STS:
Ctrl + win + Alt + Down :: Copy current line or selected line to below
Ctrl + win + Alt + Up :: Copy current line or selected line to above
If .DS_Store was never added to your git repository, simply add it to your .gitignore file.
If you don't have one, create a file called
.gitignore
In the root directory of your app and simply write
**/.DS_Store
In it. This will never allow the .DS_Store file to sneak in your git.
But, if it's already there, write in your terminal:
find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch
then commit and push the changes to remove the .DS_Store from your remote repo:
git commit -m "Remove .DS_Store from everywhere"
git push origin master
And now add .DS_Store to your .gitignore file, and then again commit and push with the 2 last pieces of code (git commit..., git push...)
Use the GD library or ImageMagick. I googled 'PHP GD merge images' and got several articles on doing this. In the past what I've done is create a large blank image, and then used imagecopymerge() to paste those images into my original blank one. Check out the articles on google you'll find some source code you can start using right away.

This is due to App Store will sync the data across servers.
I have an open source library that does this very well. It's a four gesture library that comes with an out-of-the-box pan zoom setting. You can find it here: https://bitbucket.org/warwick/hacergestov3 Or you can download the demo app here: https://play.google.com/store/apps/details?id=com.WarwickWestonWright.HacerGestoV3Demo This is a pure canvas library so it can be used in pretty any scenario. Hope this helps.
Ok, even with the risk of never getting anyone to see this, because there are already so many answers I wanted to offer more js solutions as of the year 2020 there are plenty:
outline.js or alternatively outliner.js both libraries solving exactly the issues we all have here: remove outlines for mice but keep keyboard functionality or accessability.
So instead of deciding which is more important style or accessability, choose both!
I used this videocast to set up my GoDaddy domain with Heroku, and it worked perfectly. Very clear and well explained.
Note: Skip the part about CNAME yourdomain.com.
(note the .
) and the heroku addons:add "custom domains"
http://blog.heroku.com/archives/2009/10/7/heroku_casts_setting_up_custom_domains/
To summarize the video:
1) on GoDaddy and create a CNAME with
Alias Name: www
Host Name: proxy.heroku.com
2) check that your domain has propagated by typing host www.yourdomain.com
on the command line
3) run heroku domains:add www.yourdomain.com
4) run heroku domains:add yourdomain.com
It worked for me after these steps. Hope it works for you too!
UPDATE: things have changed, check out this post Heroku/GoDaddy: send naked domain to www

Use it You can also use it with nbconvert:
jupyter-nbconvert --to PDFviaHTML filename.ipynb
which will create a file called filename.pdf.
or pip install notebook-as-pdf
create pdf from notebook jupyter-nbconvert-toPDFviaHTML
numpy.ndarray()
is a class, while numpy.array()
is a method / function to create ndarray
.
In numpy docs if you want to create an array from ndarray
class you can do it with 2 ways as quoted:
1- using array()
, zeros()
or empty()
methods:
Arrays should be constructed using array, zeros or empty (refer to the See Also section below). The parameters given here refer to a low-level method (ndarray(…)
) for instantiating an array.
2- from ndarray
class directly:
There are two modes of creating an array using __new__
:
If buffer is None, then only shape, dtype, and order are used.
If buffer is an object exposing the buffer interface, then all keywords are interpreted.
The example below gives a random array because we didn't assign buffer value:
np.ndarray(shape=(2,2), dtype=float, order='F', buffer=None) array([[ -1.13698227e+002, 4.25087011e-303], [ 2.88528414e-306, 3.27025015e-309]]) #random
another example is to assign array object to the buffer example:
>>> np.ndarray((2,), buffer=np.array([1,2,3]), ... offset=np.int_().itemsize, ... dtype=int) # offset = 1*itemsize, i.e. skip first element array([2, 3])
from above example we notice that we can't assign a list to "buffer" and we had to use numpy.array() to return ndarray object for the buffer
Conclusion: use numpy.array()
if you want to make a numpy.ndarray()
object"
I just got the same problem and to fix it, I opened the task manager and killed the adb.exe process, then I restarted Eclipse.

Try this,
Using foreach
Loop:
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox chk = row.Cells[0].Controls[0] as CheckBox;
if (chk != null && chk.Checked)
{
// ...
}
}
Use it in OnRowCommand
event and get checked CheckBox value.
GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
int requisitionId = Convert.ToInt32(e.CommandArgument);
CheckBox cbox = (CheckBox)row.Cells[3].Controls[0];
$myObj = new stdClass();
// OR
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
I love how easy is to create objects of anonymous type in JavaScript:
//JavaScript
var myObj = {
foo: "Foo value",
bar: "Bar value"
};
console.log(myObj.foo); //Output: Foo value
So I always try to write this kind of objects in PHP like javascript does:
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
//PHP < 5.4
$myObj = (object) array(
"foo" => "Foo value",
"bar" => "Bar value"
);
echo $myObj->foo; //Output: Foo value
But as this is basically an array you can't do things like assign anonymous functions to a property like js does:
//JavaScript
var myObj = {
foo: "Foo value",
bar: function(greeting) {
return greeting + " bar";
}
};
console.log(myObj.bar("Hello")); //Output: Hello bar
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => function($greeting) {
return $greeting . " bar";
}
];
var_dump($myObj->bar("Hello")); //Throw 'undefined function' error
var_dump($myObj->bar); //Output: "object(Closure)"
Well, you can do it, but IMO isn't practical / clean:
$barFunc = $myObj->bar;
echo $barFunc("Hello"); //Output: Hello bar
Also, using this synthax you can find some funny surprises, but works fine for most cases.
I recently moved a site using SimplePie (http://simplepie.org/) from a server that was using PHP 5.2.17 to one that is using PHP 5.3.2. It was after this move that I began receiving a list of error messages such as this one:
Deprecated: Assigning the return value of new by reference is deprecated in .../php/simplepie.inc on line 738
After reviewing several discussions of this issue, I cleared things up by replacing all the instances of =& new with = new in the simplepie.inc file.
I'm not experienced enough to know if this will work in all instances where these error messages are received but it worked in this particular case and it may be worth trying.
Webkit browsers support the ability to add "stroke" to fonts. This bit of style makes fonts look thinner (assuming a white background):
-webkit-text-stroke: 2px white;
Example on codepen here: http://codepen.io/mackdoyle/pen/yrgEH Some people are using SVG for a cross-platform "stroke" solution: http://codepen.io/CrocoDillon/pen/dGIsK
From the XML specification:
To allow attribute values to contain both single and double quotes, the apostrophe or single-quote character (') may be represented as "'", and the double-quote character (") as """.
Multiply your rating by 2, then round using Math.Round(rating, MidpointRounding.AwayFromZero)
, then divide that value by 2.
Math.Round(value * 2, MidpointRounding.AwayFromZero) / 2
In case that you're interested in specific lines, use a result-array:
declare RESULT=($(./myscript)) # (..) = array
echo "First line: ${RESULT[0]}"
echo "Second line: ${RESULT[1]}"
echo "N-th line: ${RESULT[N]}"
You could also get this error when JRE is not set. If so, try adding JRE System Library to your project.

You can also put the fieldset inside a table, like so:

In your controller class, just add @ComponentScan("package") annotation. In my case the package name is com.shoppingcart.So i wrote the code as @ComponentScan("com.shoppingcart") and it worked for me.
This is all you need to read.

If you're searching for hits within a larger text, you don't want to use ^
and $
as some other responders have said; those match the beginning and end of the text. Try this instead:
\bdbo\.\w+_fn\b
\b
is a word boundary: it matches a position that is either preceded by a word character and not followed by one, or followed by a word character and not preceded by one. This regex will find what you're looking for in any of these strings:
dbo.functionName_fn
foo dbo.functionName_fn bar
(dbo.functionName_fn)
...but not in this one:
foodbo.functionName_fnbar
\w+
matches one or more "word characters" (letters, digits, or _
). If you need something more inclusive, you can try \S+
(one or more non-whitespace characters) or .+?
(one or more of any characters except linefeeds, non-greedily). The non-greedy +?
prevents it from accidentally matching something like dbo.func1_fn dbo.func2_fn
as if it were just one hit.
As far as i know there is no solution for PHP to fix this. All other (above and below) answers given in this thread are nonsense.
The number_format function returns a string as result as written in PHP.net's own specification.
Functions like floatval/doubleval do return integers if you give as value 3.00 .
If you do typejuggling then you will get an integer as result.
If you use round() then you will get an integer as result.
The only possible solution that i can think of is using your database for type conversion to float. MySQL for example:
SELECT CAST('3.00' AS DECIMAL) AS realFloatValue;
Execute this using an abstraction layer which returns floats instead of strings and there you go.
If you are looking for a solution to fix your JSON output to hold 2 decimals then you can probably use post-formatting like in the code below:
// PHP AJAX Controller
// some code here
// transform to json and then convert string to float with 2 decimals
$output = array('x' => 'y', 'price' => '0.00');
$json = json_encode($output);
$json = str_replace('"price":"'.$output['price'].'"', '"price":'.$output['price'].'', $json);
// output to browser / client
print $json;
exit();
Returns to client/browser:
{"x":"y","price":0.00}
To make the dump to a source code control system that little bit faster, you can see which objects have changed since last time by using the version information in sysobjects.
Setup: Create a table in each database you want to check incrementally to hold the version information from the last time you checked it (empty on the first run). Clear this table if you want to re-scan your whole data structure.
IF ISNULL(OBJECT_ID('last_run_sysversions'), 0) <> 0 DROP TABLE last_run_sysversions
CREATE TABLE last_run_sysversions (
name varchar(128),
id int, base_schema_ver int,
schema_ver int,
type char(2)
)
Normal running mode: You can take the results from this sql, and generate sql scripts for just the ones you're interested in, and put them into a source control of your choice.
IF ISNULL(OBJECT_ID('tempdb.dbo.#tmp'), 0) <> 0 DROP TABLE #tmp
CREATE TABLE #tmp (

ORDER BY Priority ASC
Note: If you use a non-standard collation in any of your databases, you will need to replace /* COLLATE */
with your database collation. i.e. COLLATE Latin1_General_CI_AI
For anyone else having the same problem, I figured it out myself.
<html>_x000D_
<body>_x000D_
<form target="_blank" action="https://website.com/action.php" method="POST">_x000D_
<input type="hidden" name="fullname" value="Sam" />_x000D_
<input type="hidden" name="city" value="Dubai " />_x000D_
<input onclick="window.location.href = 'https://website.com/my-account';" type="submit" value="Submit request" />_x000D_
</form>_x000D_

_x000D_
All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.
As I'm using a laravel/php backend I tend to go with something like this:
/resource?filters[status_id]=1&filters[city]=Sydney&page=2&include=relatedResource
PHP automatically turns []
params into an array, so in this example I'll end up with a $filter
variable that holds an array/object of filters, along with a page and any related resources I want eager loaded.
If you use another language, this might still be a good convention and you can create a parser to convert []
to an array.
After looking on the accepted answer I realized that if know size of required vector then we have to use a loop to initialize every element
But I found new to do this using default_structure_element like following...
#include <bits/stdc++.h>
typedef long long ll;
using namespace std;
typedef struct subject {
string name;
int marks;
int credits;
}subject;
int main(){
subject default_subject;
default_subject.name="NONE";
default_subject.marks = 0;
default_subject.credits = 0;
vector <subject> sub(10,default_subject); // default_subject to initialize
//to check is it initialised
for(ll i=0;i<sub.size();i++) {
cout << sub[i].name << " " << sub[i].marks << " " << sub[i].credits << endl;
}
}
Then I think its good to way to initialize a vector of the struct, isn't it?
you may check from a python notebook cell as follows

According to the docs for File.Move there is no "overwrite if exists" parameter. You tried to specify the destination folder, but you have to give the full file specification.
Reading the docs again ("providing the option to specify a new file name"), I think, adding a backslash to the destination folder spec may work.

I used this other Stackoverflow Q&A material instead, it worked great for me:
If you are like me and Photoshop is out of your price range or just overkill for what you need. Acorn 5 is a much cheaper version of Photoshop with a lot of the same features. One of those features being a color change option. You can import all of the basic image formats including SVG and PNG. The color editing software works great and allows for basic color selection, RBG selection, hex code, or even a color grabber if you do not know the color. These color features, plus a whole lot image editing features, is definitely worth the $30. The only downside is that is currently only available on Mac.
Without VBA...
If you can use a helper column, you can use the MATCH
function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match
To simply identify duplicates, use a helper column
Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:
=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")
Drag/copy this forumla down, and it should identify the duplicates.
To highlight cells, use conditional formatting:
With some tinkering, you can use this MATCH
function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.
Something like:
=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))
For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:
=B1="Duplicate"
This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.
find . -type d | while read file; do echo $file; done
However, doesn't work if the file-name contains newlines. The above is the only solution i know of when you actually want to have the directory name in a variable. If you just want to execute some command, use xargs.
find . -type d -print0 | xargs -0 echo 'The directory is: '
With systemjs what I did is, inside my systemjs.config I added map for moment
map: {
.....,
'moment': 'node_modules/moment/moment.js',

}
And then you can easily import moment
just by doing
import * as moment from 'moment'

Presumably you have it in a variable and are using JSON.parse(data);
. In which case, use:
JSON.parse(data.replace(/"/g,'"'));
You might want to fix your JSON-writing script though, because "
is not valid in a JSON object.
Write it as a one-liner:
figure('position', [0, 0, 200, 500]) % create new figure with specified size
We can also do the same using java 8.

@Richie Cotton has a pretty good answer above. I can only add that this page provides some examples. Try the following:
x <- 1:20
y <- runif(20)
plot(x,y,xaxt = "n")
axis(side = 1, at = x, labels = FALSE, tck = -0.01)
The default value of end
is \n
meaning that after the print
statement it will print a new line. So simply stated end
is what you want to be printed after the print
statement has been executed
Eg: - print ("hello",end=" +")
will print hello +
Just putting it in src/main/resources
will bundle it inside the artifact. E.g. if your artifact is a JAR, you will have the log4j.properties
file inside it, losing its initial point of making logging configurable.
I usually put it in src/main/resources
, and set it to be output to target like so:
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<targetPath>${project.build.directory}</targetPath>
<includes>
<include>log4j.properties</include>
</includes>
</resource>
</resources>
</build>
Additionally, in order for log4j to actually see it, you have to add the output directory to the class path.
If your artifact is an executable JAR, you probably used the maven-assembly-plugin to create it. Inside that plugin, you can add the current folder of the JAR to the class path by adding a Class-Path
manifest entry like so:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.your-package.Main</mainClass>
</manifest>
<manifestEntries>
<Class-Path>.</Class-Path>
</manifestEntries>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance merges -->
<phase>package</phase> <!-- bind to the packaging phase -->
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
Now the log4j.properties file will be right next to your JAR file, independently configurable.
To run your application directly from Eclipse, add the resources
directory to your classpath in your run configuration: Run->Run Configurations...->Java Application->New
select the Classpath
tab, select Advanced
and browse to your src/resources
directory.
To understand circular dependencies, you need to remember that Python is essentially a scripting language. Execution of statements outside methods occurs at compile time. Import statements are executed just like method calls, and to understand them you should think about them like method calls.
When you do an import, what happens depends on whether the file you are importing already exists in the module table. If it does, Python uses whatever is currently in the symbol table. If not, Python begins reading the module file, compiling/executing/importing whatever it finds there. Symbols referenced at compile time are found or not, depending on whether they have been seen, or are yet to be seen by the compiler.
Imagine you have two source files:
File X.py
def X1:
return "x1"
from Y import Y2
def X2:
return "x2"
File Y.py
def Y1:
return "y1"
from X import X1
def Y2:
return "y2"
Now suppose you compile file X.py. The compiler begins by defining the method X1, and then hits the import statement in X.py. This causes the compiler to pause compilation of X.py and begin compiling Y.py. Shortly thereafter the compiler hits the import statement in Y.py. Since X.py is already in the module table, Python uses the existing incomplete X.py symbol table to satisfy any references requested. Any symbols appearing before the import statement in X.py are now in the symbol table, but any symbols after are not. Since X1 now appears before the import statement, it is successfully imported. Python then resumes compiling Y.py. In doing so it defines Y2 and finishes compiling Y.py. It then resumes compilation of X.py, and finds Y2 in the Y.py symbol table. Compilation eventually completes w/o error.
Something very different happens if you attempt to compile Y.py from the command line. While compiling Y.py, the compiler hits the import statement before it defines Y2. Then it starts compiling X.py. Soon it hits the import statement in X.py that requires Y2. But Y2 is undefined, so the compile fails.
Please note that if you modify X.py to import Y1, the compile will always succeed, no matter which file you compile. However if you modify file Y.py to import symbol X2, neither file will compile.
Any time when module X, or any module imported by X might import the current module, do NOT use:
from X import Y
Any time you think there may be a circular import you should also avoid compile time references to variables in other modules. Consider the innocent looking code:
import X
z = X.Y
Suppose module X imports this module before this module imports X. Further suppose Y is defined in X after the import statement. Then Y will not be defined when this module is imported, and you will get a compile error. If this module imports Y first, you can get away with it. But when one of your co-workers innocently changes the order of definitions in a third module, the code will break.
In some cases you can resolve circular dependencies by moving an import statement down below symbol definitions needed by other modules. In the examples above, definitions before the import statement never fail. Definitions after the import statement sometimes fail, depending on the order of compilation. You can even put import statements at the end of a file, so long as none of the imported symbols are needed at compile time.
Note that moving import statements down in a module obscures what you are doing. Compensate for this with a comment at the top of your module something like the following:
#import X (actual import moved down to avoid circular dependency)
In general this is a bad practice, but sometimes it is difficult to avoid.
This might be seen as a little complex but does exactly what you want
SELECT

In my case it was caused by a wrong Content-Type
in the HTTP POST. Setting it to text/xml
solved the problem.
Please see @jlareau answer here: https://stackoverflow.com/questions/11534710/angularjs-how-to-use-routeparams-in-generating-the-templateurl
You can use a function to generate the template string:
var app = angular.module('app',[]);
app.config(
function($routeProvider) {
$routeProvider.
when('/', {templateUrl:'/home'}).
when('/users/:user_id',
{
controller:UserView,
templateUrl: function(params){ return '/users/view/' + params.user_id; }
}
).
otherwise({redirectTo:'/'});
}
);
FragmentActivity
gives you all of the functionality of Activity
plus the ability to use Fragments which are very useful in many cases, particularly when working with the ActionBar, which is the best way to use Tabs in Android.
If you are only targeting Honeycomb (v11) or greater devices, then you can use Activity
and use the native Fragments introduced in v11 without issue. FragmentActivity
was built specifically as part of the Support Library to back port some of those useful features (such as Fragments) back to older devices.
I should also note that you'll probably find the Backward Compatibility - Implementing Tabs training very helpful going forward.
The ideas provided above are good. For fast access (in case you would like to make a real time application) you could try the following:
//suppose you read an image from a file that is gray scale
Mat image = imread("Your path", CV_8UC1);
//...do some processing
uint8_t *myData = image.data;
int width = image.cols;
int height = image.rows;
int _stride = image.step;//in case cols != strides
for(int i = 0; i < height; i++)
{
for(int j = 0; j < width; j++)
{
uint8_t val = myData[ i * _stride + j];
//do whatever you want with your value
}
}
Pointer access is much faster than the Mat.at<> accessing. Hope it helps!
This library helped me, I had a dict list of nested keys with the same name but with different values, every other solution kept overriding those nested keys.
https://pypi.org/project/deepmerge/
from deepmerge import always_merger
def process_parms(args):
temp_list = []
for x in args:
with open(x, 'r') as stream:
temp_list.append(yaml.safe_load(stream))
return always_merger.merge(*temp_list)
Use:
#include <windows.h>
Sleep(sometime_in_millisecs); // Note uppercase S
And here's a small example that compiles with MinGW and does what it says on the tin:
#include <windows.h>
#include <stdio.h>
int main() {
printf( "starting to sleep...\n" );
Sleep(3000); // Sleep three seconds
printf("sleep ended\n");
}
Starting Scala 2.13
, the standard library provides a dedicated resource management utility: Using
.
It can be used in this case with resources such as PrintWriter
or BufferedWriter
which extends AutoCloseable
in order to write to a file and, no matter what, close the resource afterwards:
For instance, with java.io
api:
import scala.util.Using, java.io.{PrintWriter, File}
// val lines = List("hello", "world")
Using(new PrintWriter(new File("file.txt"))) {
writer => lines.foreach(writer.println)
}
Or with java.nio
api:
import scala.util.Using, java.nio.file.{Files, Paths}, java.nio.charset.Charset
// val lines = List("hello", "world")
Using(Files.newBufferedWriter(Paths.get("file.txt"), Charset.forName("UTF-8"))) {
writer => lines.foreach(line => writer.write(line + "\n"))
}
The easiest thing to do is to move the file from your local directory temporarily, then commit changes to your remote repo. Then add it back to your local repo, make sure to update .gitignore so it doesn't commit to remote again
You can use the event.target.result to reset the input from a component directly.
event.target.value = ""
Depending on what you want to do you could do this:
template<typename Base, typename T>
inline bool instanceof(const T*) {
return std::is_base_of<Base, T>::value;
}
Use:
if (instanceof<BaseClass>(ptr)) { ... }
However, this purely operates on the types as known by the compiler.
Edit:
This code should work for polymorphic pointers:
template<typename Base, typename T>
inline bool instanceof(const T *ptr) {
return dynamic_cast<const Base*>(ptr) != nullptr;
}
Example: http://cpp.sh/6qir
One aspect that is missing in other answers. It's true that in general the pattern is:
__str__
: human-readable__repr__
: unambiguous, possibly machine-readable via eval
Unfortunately, this differentiation is flawed, because the Python REPL and also IPython use __repr__
for printing objects in a REPL console (see related questions for Python and IPython). Thus, projects which are targeted for interactive console work (e.g., Numpy or Pandas) have started to ignore above rules and provide a human-readable __repr__
implementation instead.
You can use the Android app Barcode Scanner Terminal (DISCLAIMER! I'm the developer). It can scan the barcode and send it to the PC and in your case enter it on the web form. More details here.
Angular is based on observable instead of promise base as of angularjs 1.x, so when we try to get data using http
it returns observable instead of promise, like you did
return this.http
.get(this.configEndPoint)
.map(res => res.json());
then to get data and show on view we have to convert it into desired form using RxJs functions like .map() function and .subscribe()
.map() is used to convert the observable (received from http request)to any form like .json(), .text()
as stated in Angular's official website,
.subscribe() is used to subscribe those observable response and ton put into some variable so from which we display it into the view
this.myService.getConfig().subscribe(res => {
console.log(res);
this.data = res;
});
This call will give you the information you want.
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
You can disable scrolling by freezing your RecyclerView.
To freeze:
recyclerView.setLayoutFrozen(true)
To unfreeze: recyclerView.setLayoutFrozen(false)
for a 2-D tensor, you can get the number of rows and columns as int32 using the following code:
rows, columns = map(lambda i: i.value, tensor.get_shape())
This will generate assembly code with the C code + line numbers interweaved, to more easily see which lines generate what code:
# create assembler code:
g++ -S -fverbose-asm -g -O2 test.cc -o test.s
# create asm interlaced with source lines:
as -alhnd test.s > test.lst
Found in Algorithms for programmers, page 3 (which is the overall 15th page of the PDF).
You can use numpy's slicing, simply start:stop:step
.
>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])
This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2] # O(1), constant time
>>> b[:] = 0 # modifying the view changes original array
>>> a # original array is modified
array([0, 2, 0, 4, 0])
so if either of the above things are a problem, you can make a copy explicitly:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy() # explicit copy, O(n)
>>> b[:] = 0 # modifying the copy
>>> a # original is intact
array([1, 2, 3, 4, 5])
This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.
Note that there are multiple iPad Pros, each with a different Viewports: When emulating an iPad Pro via the Chrome developer tools, the iPad Pro (12.9") is the default option. If you want to emulate one of the other iPad Pros (10.5" or 9.7") with a different viewport, you'll need to add a custom emulated device with the correct specs.
You can search devices, viewports, and their respective CSS media queries at: http://vizdevices.yesviz.com/devices.php.
For instance, the iPad Pro (12.9") would have the following media queries:
/* Landscape */
@media only screen and (min-width: 1366px) and (orientation: landscape) { /* Your Styles... */ }
/*Portrait*/
@media only screen and (min-width: 1024px) and (orientation: portrait) { /* Your Styles... */ }
Whereas the iPad Pro (10.5") will have:
/* Landscape */
@media only screen and (min-device-width: 1112px) and (orientation: landscape) { /* Your Styles... */ }
/*Portrait*/
@media only screen and (min-device-width: 834px) and (orientation: portrait) { /* Your Styles... */ }
You can check if the port is being used by other program using WAMP menu -
Click on WAMP icon select Apache -> Service -> Test Port 80
, this will check if the port is used by any other program
Also do this select Apache -> Service -> Install Service
, this will make apache use port 80 if the port is not already used by any other program like IIS or Skype
Restart the WAMP see if the problem is fixed.
If port 80 is already used by some program, then you can choose other listening port for WAMP. To do this -
click WAMP icon -> Apache -> httpd.conf
Now find listen 80
(where 80 is port number, it can be different on your system)
Now change that to something else like 3333, you can access WAMP homepage by typing localhost:3333
or 127.0.0.1:3333
in browser's address bar.
If you want WAMP to use port 80, uninstall the program that is using port 80 and then do things stated in step 2 or you can change port in that program's setting, also check httpd.conf
file for listen [port]
line.
It should be as simple as running this:
mysql -u <user> -p < db_backup.dump
If the dump is of a single database you may have to add a line at the top of the file:
USE <database-name-here>;
If it was a dump of many databases, the use statements are already in there.
To run these commands, open up a command prompt (in Windows) and cd
to the directory where the mysql.exe
executable is (you may have to look around a bit for it, it'll depend on how you installed mysql, i.e. standalone or as part of a package like WAMP). Once you're in that directory, you should be able to just type the command as I have it above.
With version 1.7 of the official 10gen driver, this is the current (non-obsolete) API:
const string uri = "mongodb://localhost/mydb";
var client = new MongoClient(uri);
var db = client.GetServer().GetDatabase(new MongoUrl(uri).DatabaseName);
var collection = db.GetCollection("mycollection");
Same thing but in ANSI way
SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME IN ( SELECT TABLE_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME = 'CreateDate' )
Basic:
string[] myString = new string[]{"string1", "string2"};
or
string[] myString = new string[4];
myString[0] = "string1"; // etc.
Advanced: From a List
list<string> = new list<string>();
//... read this in from somewhere
string[] myString = list.ToArray();
From StringCollection
StringCollection sc = new StringCollection();
/// read in from file or something
string[] myString = sc.ToArray();
NodeJS now includes threads (as an experimental feature at time of answering).
Another difference is that <import>
allows importing by referring to another namespace. <include>
only allows importing by referring to a URI of intended include schema. That is definitely another difference than inter-intra namespace importing.
For example, the xml schema validator may already know the locations of all schemas by namespace already. Especially considering that referring to XML namespaces by URI may be problematic on different systems where classpath:// means nothing, or where http:// isn't allowed, or where some URI doesn't point to the same thing as it does on another system.
Code sample of valid and invalid imports and includes:
Valid:
<xsd:import namespace="some/name/space"/>
<xsd:import schemaLocation="classpath://mine.xsd"/>
<xsd:include schemaLocation="classpath://mine.xsd"/>
Invalid:
<xsd:include namespace="some/name/space"/>

// x + y + z = 0 => -z = x + y
final Set<Integer> z = new HashSet<>(length);
int zeroCounter = 0, sum; // if they're more than 3 zeros we're done
for (int element : input) {
if (element < 0) {
z.add(element);
}
if (element == 0) {
++zeroCounter;
if (zeroCounter >= 3) {
return true;
}
}
}
if (z.isEmpty() || z.size() == length || (z.size() + zeroCounter == length)) {
return false;
} else {
for (int x = 0; x < length; ++x) {
for (int y = x + 1; y < length; ++y) {
sum = input[x] + input[y]; // will use it as inverse addition
if (sum < 0) {
continue;
}
if (z.contains(sum * -1)) {
return true;
}
}
}

I added some unit tests here: GivenArrayReturnTrueIfThreeElementsSumZeroTest.
If the set is using too much space I can easily use a java.util.BitSet that will use O(n/w) space.
Simplest way for create SSL certificate
Open Firefox (I suppose it's also possible with Chrome, but it's easier for me with FF)
Visit your development site with a self-signed SSL certificate.
Click on the certificate (next to the site name)
Click on "More information"
Click on "View certificate"
Click on "Details"
Click on "Export..."
Choose "X.509 Certificate whith chain (PEM)", select the folder and name to save it and click "Save"
Go to command line, to the directory where you downloaded the pem file and execute "openssl x509 -inform PEM -outform DM -in .pem -out .crt"
Copy the .crt file to the root of the /sdcard folder inside your Android device Inside your Android device, Settings > Security > Install from storage.
It should detect the certificate and let you add it to the device Browse to your development site.
The first time it should ask you to confirm the security exception. That's all.
The certificate should work with any browser installed on your Android (Browser, Chrome, Opera, Dolphin...)
Remember that if you're serving your static files from a different domain (we all are page speed bitches) you also need to add the certificate for that domain.
Use getpass.getpass()
:
from getpass import getpass
password = getpass()
An optional prompt can be passed as parameter; the default is "Password: "
.
Note that this function requires a proper terminal, so it can turn off echoing of typed characters – see “GetPassWarning: Can not control echo on the terminal” when running from IDLE for further details.
listview.setOnItemClickListener(new OnItemClickListener(){
//setting onclick to items in the listview.
@Override
public void onItemClick(AdapterView<?>adapter,View v, int position){
Intent intent;
switch(position){
// case 0 is the first item in the listView.
case 0:
intent = new Intent(Activity.this,firstActivity.class);
break;
//case 1 is the second item in the listView.
case 1:
intent = new Intent(Activity.this,secondActivity.class);
break;
case 2:
intent = new Intent(Activity.this,thirdActivity.class);
break;
//add more if you have more items in listView
startActivity(intent);
}
});
This will only work for windows which are opened by using window.open(); method. Try this
var tmp=window.open(params);
tmp.close();
Working with a dictionary ->level2 above comes from a dictionary in my case (just in case anybody will find it useful) Trying the first example I stumbled over this error: "This document already has a 'DocumentElement' node." I was inspired by the answer here
and edited my code: (xmlDoc.DocumentElement.AppendChild(body))
//a dictionary:
Dictionary<string, string> Level2Data
{
{"level2", "text"},
{"level2", "other text"},
{"same_level2", "more text"}
}
//xml Decalration:
XmlDocument xmlDoc = new XmlDocument();
XmlDeclaration xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);
XmlElement root = xmlDoc.DocumentElement;
xmlDoc.InsertBefore(xmlDeclaration, root);
// add body
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.AppendChild(body);
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.DocumentElement.AppendChild(body); //without DocumentElement ->ERR
foreach (KeyValuePair<string, string> entry in Level2Data)
{
//write to xml: - it works version 1.
XmlNode keyNode = xmlDoc.CreateElement(entry.Key); //open TAB
keyNode.InnerText = entry.Value;
body.AppendChild(keyNode); //close TAB
//Write to xmml verdion 2: (uncomment the next 4 lines and comment the above 3 - version 1
//XmlElement key = xmlDoc.CreateElement(string.Empty, entry.Key, string.Empty);
//XmlText value = xmlDoc.CreateTextNode(entry.Value);
//key.AppendChild(value);
//body.AppendChild(key);
}
Both versions (1 and 2 inside foreach loop) give the output:
<?xml version="1.0" encoding="UTF-8"?>
<body>
<level1>
<level2>text</level2>
<level2>ther text</level2>
<same_level2>more text</same_level2>
</level1>
</body>
(Note: third line "same level2" in dictionary can be also level2 as the others but I wanted to ilustrate the advantage of the dictionary - in my case I needed level2 with different names.
Dynamically, if you want to remove (a) part(s) from (a) fixed index(es) of a string, use this function:
/**
* Removes index/indexes from a string, using a delimiter.
*
* @param string $string
* @param int|int[] $index An index, or a list of indexes to be removed from string.
* @param string $delimiter
* @return string
* @todo Note: For PHP versions lower than 7.0, remove scalar type hints (i.e. the
* types before each argument) and the return type.
*/
function removeFromString(string $string, $index, string $delimiter = " "): string
{
$stringParts = explode($delimiter, $string);
// Remove indexes from string parts
if (is_array($index)) {
foreach ($index as $i) {
unset($stringParts[(int)($i)]);
}
} else {
unset($stringParts[(int)($index)]);
}
// Join all parts together and return it
return implode($delimiter, $stringParts);
}
For your purpose:
remove_from_str("REGISTER 11223344 here", 1); // Output: REGISTER here
One of its usages is to execute command-like strings, which you know their structures.
// apparently this is broken. Whoops for me!
java.util.Collections.fill(list,new Integer(0));
// this is better
Integer[] data = new Integer[60];
Arrays.fill(data,new Integer(0));
List<Integer> list = Arrays.asList(data);
You can get it writing less without external libraries:
String hex = (new HexBinaryAdapter()).marshal(md5.digest(YOUR_STRING.getBytes()))

I've had the problem which was two pronged:
1. In a form with multiple select2 elements, the dropdown won't open on tab, and you need to press space key to open it
2. Once you have made a selection, the tabindex won't be honored and you have to manually click on the next input field
While the usual suggestions worked, I came up with my own version, since a library script was doing the conversion of normal select to select2, and hence I had no control over this initialization.
Here is the code that worked for me.
Tab to open
$(document).on("focus", ".select2", function() {
$(this).siblings("select").select2("open");
});
Move to next on selection
var inputs = $("input,select"); // You can use other elements such as textarea, button etc.
//depending on input field types you have used
$("select").on("select2:close",function(){
var pos = $(inputs).index(this) + 1;
var next = $(inputs).eq(pos);
setTimeout( function() {
next.focus();
if (next.siblings(".select2").length) { //If it's a select
next.select2("open");
}
}, 500); //The delay is required to allow default events to occur
});
Hope this helps.
you can use cURL library for posting data: http://www.php.net/curl

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, "http://websiteURL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "XML=".$xmlcontent."&password=".$password."&etc=etc");
$content=curl_exec($ch);
where postfield contains XML you need to send - you will need to name the postfield the API service (Clickatell I guess) expects

"abc"
is a literal String.
In Java, these literal strings are pooled internally and the same String instance of "abc"
is used where ever you have that string literal declared in your code. So "abc" == "abc"
will always be true as they are both the same String instance.
Using the String.intern()
method you can add any string you like to the internally pooled strings, these will be kept in memory until java exits.
On the other hand, using new String("abc")
will create a new string object in memory, which is logically the same as the "abc"
literal.
"abc" == new String("abc")
will always be false, as although they are logically equal they refer to different instances.
Wrapping a String constructor around a string literal is of no value, it just needlessly uses more memory than it needs to.
I think the $() syntax is easier to read...
variable=$(ps -ef | grep "port 10 -" | grep -v "grep port 10 -"| awk '{printf "%s", $12}')
But the real issue is probably that $12

Edited since the question was changed, This returns valid data, but it is not clear what the expected output of ps -ef

There is a lot of incompatibility between different versions of cglib and lots of poor advice that can be googled on this subject (use ancient versions of cglib-nodeb, etc). After wrestling with this nonsense for 3 days with an ancient version of Spring (2.5.6)I have discovered:
Where the result is negative, C truncates towards 0 rather than flooring - I learnt this reading about why Python integer division always floors here: Why Python's Integer Division Floors
You need to do the following
git fetch -p
This will update the local database of remote branches.
another way is to use the range method
foo = [1,2,3,4,5,6]
bar = [10,20,30,40,50,60]
a = foo[0...3]
b = bar[3...6]
print a + b
=> [1, 2, 3, 40, 50 , 60]
I managed to resolve the issue that caused the configuration to fail on a docker container running the Hortonworks HDP 2.6 Sandbox.
If the initial configuration fails the listener will be running and will have to be killed first:
ps -aux | grep tnslsnr
kill {process id identified above}
Then next step is then to fix the shared memory issue which makes the configuration process fail.
Oracle XE requires 1 Gb of shared memory and fails otherwise (I didn't try 512 mb) according to https://blogs.oracle.com/oraclewebcentersuite/implement-oracle-database-xe-as-docker-containers.
vi /etc/fstab
change/add the line to:
tmpfs /dev/shm tmpfs defaults,size=1024m 0 0
Then reload the configuration by:
mount -a
Keep in mind that the next time you restart the docker container you might have to do 'mount -a'.
J2EE traditionally referred to products and standards released by Sun. For example if you were developing a standard J2EE web application, you would be using EJBs, Java Server Faces, and running in an application server that supports the J2EE standard. However since there is such a huge open source plethora of libraries and products that do the same jobs as well as (and many will argue better) then these Sun offerings, the day to day meaning of J2EE has migrated into referring to these as well (For instance a Spring/Tomcat/Hibernate solution) in many minds.
This is a great book in my opinion that discusses the 'open source' approach to J2EE http://www.theserverside.com/tt/articles/article.tss?l=J2EEWithoutEJB_BookReview
I can't see why you would care. Other than the "don't use ports below 1024" privilege rule, you should be able to use any port because your clients should be configurable to talk to any IP address and port!
If they're not, then they haven't been done very well. Go back and do them properly :-)
In other words, run the server at IP address X
and port Y
then configure clients with that information. Then, if you find you must run a different server on X
that conflicts with your Y
, just re-configure your server and clients to use a new port. This is true whether your clients are code, or people typing URLs into a browser.
I, like you, wouldn't try to get numbers assigned by IANA since that's supposed to be for services so common that many, many environments will use them (think SSH or FTP or TELNET).
Your network is your network and, if you want your servers on port 1234 (or even the TELNET or FTP ports for that matter), that's your business. Case in point, in our mainframe development area, port 23 is used for the 3270 terminal server which is a vastly different beast to telnet. If you want to telnet to the UNIX side of the mainframe, you use port 1023. That's sometimes annoying if you use telnet clients without specifying port 1023 since it hooks you up to a server that knows nothing of the telnet protocol - we have to break out of the telnet client and do it properly:
telnet big_honking_mainframe_box.com 1023
If you really can't make the client side configurable, pick one in the second range, like 48042, and just use it, declaring that any other software on those boxes (including any added in the future) has to keep out of your way.

Both Abstraction and Encapsulation are two of the four basic OOP concepts which allow you to model real-world things into objects so that you can implement them in your program and code. Many beginners get confused between Abstraction and Encapsulation because they both look very similar. If you ask someone what is Abstraction, he will tell that it's an OOP concept which focuses on relevant information by hiding unnecessary detail, and when you ask about Encapsulation, many will tell that it's another OOP concept which hides data from outside world. The definitions are not wrong as both Abstraction and Encapsulation does hide something, but the key difference is on intent.
Abstraction hides complexity by giving you a more abstract picture, a sort of 10,000 feet view, while Encapsulation hides internal working so that you can change it later. In other words, Abstraction hides details at the design level, while Encapsulation hides details at the implementation level.
Update for Python3: (quoted from the already-answered answer, since the last edit/comment here suggested a deprecated method)
In Python 3,
reload
was moved to theimp
module. In 3.4,imp
was deprecated in favor ofimportlib
, andreload
was added to the latter. When targeting 3 or later, either reference the appropriate module when callingreload
or import it.
Takeaway:
importlib.reload(packagename)
imp.reload(packagename)
Use the reload
builtin function:
https://docs.python.org/2/library/functions.html#reload
When
reload(module)
is executed:
- Python modules’ code is recompiled and the module-level code reexecuted, defining a new set of objects which are bound to names in the module’s dictionary. The init function of extension modules is not called a second time.
- As with all other objects in Python the old objects are only reclaimed after their reference counts drop to zero.
- The names in the module namespace are updated to point to any new or changed objects.
- Other references to the old objects (such as names external to the module) are not rebound to refer to the new objects and must be updated in each namespace where they occur if that is desired.
Example:
# Make a simple function that prints "version 1"
shell1$ echo 'def x(): print "version 1"' > mymodule.py
# Run the module
shell2$ python
>>> import mymodule
>>> mymodule.x()
version 1
# Change mymodule to print "version 2" (without exiting the python REPL)
shell2$ echo 'def x(): print "version 2"' > mymodule.py
# Back in that same python session
>>> reload(mymodule)
<module 'mymodule' from 'mymodule.pyc'>
>>> mymodule.x()
version 2
You can use show innodb status
(or show engine innodb status
for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.
You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.
Here's what you'd want to look for:
------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status
In this case, there's just one connection to the InnoDB engine right now (my login, running the show
query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594
.
Just a little bug (Bug for me) I found on mac emulator.

Give Icomoon a try. You can upload your own SVGs, add them to the library, then create a custom font combining FontAwesome with your own icons.
I would use DATEFROMPARTS function. It is quite easy and you don't need casting. As an example this query :
Select DATEFROMPARTS(YEAR(GETDATE()), MONTH(GETDATE()), DAY(GETDATE())) as myNewDate
will return
2021-01-21
The good part you can also create you own date, for example you want first day of a month as a date, than you can just use like below:
Select DATEFROMPARTS(YEAR(GETDATE()), MONTH(GETDATE()), 1) as myNewDate
The result will be:
2021-01-01
Version 7.3 (7D175)
The Application ID Name should be same as application bundle identifier, if you application bundle identifier is com.abc.xyz than the application ID name for this bundle ID should be XC com abc xyz
A name in any other format won't be seen by Xcode.
This works in python 2 and 3 and is a bit cleaner than before, but requires SA>=1.0.

int a = srand(time(NULL));
The prototype for srand
is void srand(unsigned int)
(provided you included <stdlib.h>
).
This means it returns nothing ... but you're using the value it returns (???) to assign, by initialization, to a
.
Edit: this is what you need to do:
#include <stdlib.h> /* srand(), rand() */
#include <time.h> /* time() */
#define ARRAY_SIZE 1024
void getdata(int arr[], int n)
{
for (int i = 0; i < n; i++)
{
arr[i] = rand();
}
}
int main(void)
{
int arr[ARRAY_SIZE];
srand(time(0));
getdata(arr, ARRAY_SIZE);
/* ... */
}
Here is the slightly different C# version:

Assign the members directly without the .Value
part:
DateTimeExtended(DateTimeExtended myNewDT)
{
this.MyDateTime = myNewDT.MyDateTime;
this.otherdata = myNewDT.otherdata;
}
Make sure you have a service started and listening on the port.
netstat -ln | grep 8080

sudo netstat -tulpn
A Docker container might be built without a shell (e.g. https://github.com/fluent/fluent-bit-docker-image/issues/19).
In this case, you can copy-in a statically compiled shell and execute it, e.g.
docker create --name temp-busybox busybox:1.31.0
docker cp temp-busybox:/bin/busybox busybox
docker cp busybox mycontainerid:/busybox
docker exec -it mycontainerid /bin/busybox sh
scan
can read from a web page automatically; you don't necessarily have to mess with connections.
I've seen
anEvent.isPopupTrigger()
be used before. I'm fairly new to Java so I'm happy to hear thoughts about this approach :)
This is an old question, and I'm not sure if it will help, but I've been able to programatically fire an event using:
if (document.createEvent && ctrl.dispatchEvent) {
var evt = document.createEvent("HTMLEvents");
evt.initEvent("change", true, true);
ctrl.dispatchEvent(evt); // for DOM-compliant browsers
} else if (ctrl.fireEvent) {
ctrl.fireEvent("onchange"); // for IE
}
df['new'] = 0
For in-place modification, perform direct assignment. This assignment is broadcasted by pandas for each row.
df = pd.DataFrame('x', index=range(4), columns=list('ABC'))
df
A B C
0 x x x
1 x x x
2 x x x
3 x x x
df['new'] = 'y'
# Same as,
# df.loc[:, 'new'] = 'y'
df
A B C new
0 x x x y
1 x x x y
2 x x x y
3 x x x y
If you want to add an column of empty lists, here is my advice:
object
columns are bad news in terms of performance. Rethink how your data is structured. If you must store a column of lists, ensure not to copy the same reference multiple times.
# Wrong
df['new'] = [[]] * len(df)
# Right
df['new'] = [[] for _ in range(len(df))]
df.assign(new=0)
If you need a copy instead, use DataFrame.assign
:
df.assign(new='y')
A B C new
0 x x x y
1 x x x y
2 x x x y
3 x x x y
And, if you need to assign multiple such columns with the same value, this is as simple as,
c = ['new1', 'new2', ...]
df.assign(**dict.fromkeys(c, 'y'))
A B C new1 new2
0 x x x y y
1 x x x y y
2 x x x y y
3 x x x y y
Finally, if you need to assign multiple columns with different values, you can use assign
with a dictionary.
c = {'new1': 'w', 'new2': 'y', 'new3': 'z'}
df.assign(**c)
A B C new1 new2 new3
0 x x x w y z
1 x x x w y z
2 x x x w y z
3 x x x w y z
Before trying to adjust the size post-layout, first check what style your dialog is using. Make sure that nothing in the style tree sets
<item name="windowMinWidthMajor">...</item>
<item name="windowMinWidthMinor">...</item>
If that's happening, it's just as simple as supplying your own style to the [builder constructor that takes in a themeResId](http://developer.android.com/reference/android/app/AlertDialog.Builder.html#AlertDialog.Builder(android.content.Context, int)) available API 11+
<style name="WrapEverythingDialog" parent=[whatever you were previously using]>
<item name="windowMinWidthMajor">0dp</item>
<item name="windowMinWidthMinor">0dp</item>
</style>

You can use the border-radius attribute to give it a border-radius equivalent to the element's border-radius. For example:
<div style="border-radius 10px; -moz-border-radius 10px; -webkit-border-radius 10px; width: 20px; height: 20px; background: red; border: solid black 1px;"> </div>
(The reason for using the -moz and -webkit extensions is to support pre-CSS3-final versions of Gecko and Webkit.)
There are more examples on this page. As far as inserting text, you can do it but you have to be mindful of the positioning, as most browsers' box padding model still uses the outer square.
Yes Exactly, the only distinction is the fact it returns a value.
Simplification (not using expressions):
List<T>.ForEach
Takes an action, it doesn't expect a return result.
So an Action<T>
delegate would suffice.. say:
List<T>.ForEach(param => Console.WriteLine(param));
is the same as saying:
List<T>.ForEach(delegate(T param) { Console.WriteLine(param); });
the difference is that the param type and delegate decleration are inferred by usage and the braces aren't required on a simple inline method.
Where as
List<T>.Where
Takes a function, expecting a result.
So an Function<T, bool>
would be expected:
List<T>.Where(param => param.Value == SomeExpectedComparison);
which is the same as:
List<T>.Where(delegate(T param) { return param.Value == SomeExpectedComparison; });
You can also declare these methods inline and asign them to variables IE:
Action myAction = () => Console.WriteLine("I'm doing something Nifty!");
myAction();
or
Function<object, string> myFunction = theObject => theObject.ToString();
string myString = myFunction(someObject);
I hope this helps.

There is one more reason for such failure which I came to know when mine failed
This might not apply in this case but it also throws the same error and since this question comes up on top for this error, I have added this answer here.
The .NET component Excel Reader .NET may satisfy your requirement. It's good enought for reading XLSX and XLS files. So try it from:
java.math.BigInteger
is an immutable class so we can not assign new object in the location of already assigned object. But you can create new object to assign new value like:
sum = sum.add(BigInteger.valueOf(i));
var lat = marker.getPosition().lat();
var lng = marker.getPosition().lng();

This is modified from an answer above to support 'children' instead of a data array.
Note: The use of styled-components is of no importance to the solution.

export function AutoScrollList(props: Props) {

});
};
useEffect(() => {
scrollToBottom()
}, [props.children])
return (

I managed to resolve this issue as follows...
Be careful, make sure you understand the IDE you're using! - Because I didn't. I was trying to import xlsxwriter using PyCharm and was returning this error.
Assuming you have already attempted the pip installation (sudo pip install xlsxwriter) via your cmd prompt, try using another IDE e.g. Geany - & import xlsxwriter.
I tried this and Geany was importing the library fine. I opened PyCharm and navigated to 'File>Settings>Project:>Project Interpreter' xlslwriter was listed though intriguingly I couldn't import it! I double clicked xlsxwriter and hit 'install Package'... And thats it! It worked!
Hope this helps...
if you want to get the name of the class simply call:-
id yourObject= [AnotherClass returningObject];
NSString *className=[yourObject className];
NSLog(@"Class name is : %@",className);
With Entity Framework 6, you can use Remove
.
Also it 's a good tactic to use using
for being sure that your connection is closed.
using (var context = new EmployDbContext())
{
Employ emp = context.Employ.Where(x => x.Id == id).Single<Employ>();
context.Employ.Remove(emp);
context.SaveChanges();
}
Lambda Expression Java 8
In Java 1.8 (Java 8) this has become lot easier by using forEach method from Aggregate operations(Stream operations) that looks similar to iterators from Iterable Interface.
Just copy paste below statement to your code and rename the HashMap variable from hm to your HashMap variable to print out key-value pair.
HashMap<Integer,Integer> hm = new HashMap<Integer, Integer>();
/*
* Logic to put the Key,Value pair in your HashMap hm
*/
// Print the key value pair in one line.
hm.forEach((k,v) -> System.out.println("key: "+k+" value:"+v));
Here is an example where a Lambda Expression is used:
HashMap<Integer,Integer> hm = new HashMap<Integer, Integer>();
Random rand = new Random(47);
int i=0;
while(i<5){
i++;
int key = rand.nextInt(20);
int value = rand.nextInt(50);
System.out.println("Inserting key: "+key+" Value: "+value);
Integer imap =hm.put(key,value);
if( imap == null){
System.out.println("Inserted");
}
else{
System.out.println("Replaced with "+imap);
}
}
hm.forEach((k,v) -> System.out.println("key: "+k+" value:"+v));
Output:
Inserting key: 18 Value: 5
Inserted
Inserting key: 13 Value: 11
Inserted
Inserting key: 1 Value: 29
Inserted
Inserting key: 8 Value: 0
Inserted
Inserting key: 2 Value: 7
Inserted
key: 1 value:29
key: 18 value:5
key: 2 value:7
key: 8 value:0
key: 13 value:11
Also one can use Spliterator for the same.
Spliterator sit = hm.entrySet().spliterator();
UPDATE
Including documentation links to Oracle Docs. For more on Lambda go to this link and must read Aggregate Operations and for Spliterator go to this link.
Add the following CSS:
For the parent div:
style="display: flex;"
For child div:
style="align-items: stretch;"
When we first moved over to Vista with Oracle 10g, we experienced this issue when we installed the Oracle client on our Vista boxes, even when we were running with admin privileges during install.
Oracle brought out a new version of the 10g client (10.2.0.3) that was Vista compatible.
I do believe that this was after 11g was released, so it is possible that there is a 'Vista compatible' version for 11g also.
In my case I'm doing it like this:
module SayHi {
export default () => { console.log("Hi"); }
}
new SayHi();
$('#maindivid').find('input .inputclass').length
Sequences have a method index(value)
which returns index of first occurrence - in your case this would be verts.index(value)
.
You can run it on verts[::-1]
to find out the last index. Here, this would be len(verts) - 1 - verts[::-1].index(value)

I resolve this (On Eclipse IDE) by delete my old server and create the same again. This error is because you don't proper terminate Tomcat server and close Eclipse.
I saw the answers here, and it is answering the question of sharing data between controllers, but what should I do if I want one controller to notify the other about the fact that the data has been changed (without using broadcast)? EASY! Just using the famous visitor pattern:
myApp.service('myService', function() {
var visitors = [];
var registerVisitor = function (visitor) {
visitors.push(visitor);
}
var notifyAll = function() {
for (var index = 0; index < visitors.length; ++index)
visitors[index].visit();
}
var myData = ["some", "list", "of", "data"];
var setData = function (newData) {
myData = newData;
notifyAll();
}
var getData = function () {
return myData;
}
return {
registerVisitor: registerVisitor,
setData: setData,
getData: getData
};
}
myApp.controller('firstController', ['$scope', 'myService',
function firstController($scope, myService) {
var setData = function (data) {
myService.setData(data);
}
}
]);
myApp.controller('secondController', ['$scope', 'myService',
function secondController($scope, myService) {
myService.registerVisitor(this);
this.visit = function () {
$scope.data = myService.getData();
}
$scope.data = myService.getData();
}
]);
In this simple manner, one controller can update another controller that some data has been updated.

Webkit browsers set the height and width property after the image is loaded. Instead of using timeouts, I'd recommend using an image's onload event. Here's a quick example:
var img = $("img")[0]; // Get my img elem
var pic_real_width, pic_real_height;
$("<img/>") // Make in memory copy of image to avoid css issues
.attr("src", $(img).attr("src"))
.load(function() {
pic_real_width = this.width; // Note: $(this).width() will not
pic_real_height = this.height; // work for in memory images.
});
To avoid any of the effects CSS might have on the image's dimensions, the code above makes an in memory copy of the image. This is a very clever solution suggested by FDisk.
You can also use the naturalHeight
and naturalWidth
HTML5 attributes.

I just had thesame problem. With me the exe was still running but I could not end it with the Task Manager. Just by restarting VS, it worked for me.
