Create a template file and use a template engine to read/update the file. It will increase your code's maintainability in the future as well as separate display from logic.
An example using Smarty:
Template File
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head><title>{$title}</title></head>
<body>{$string}</body>
</html>
Code
function TestBlockHTML(){
$smarty = new Smarty();
$smarty->assign('title', 'My Title');
$smarty->assign('string', $replStr);
return $smarty->render('template.tpl');
}
<input type="text" formControlName="gsm" (input)="formatGsm($event.target.value)">
formatGsm(inputValue: String): String {
const value = inputValue.replace(/[^0-9]/g, ''); // remove except digits
let format = '(***) *** ** **'; // You can change format
for (let i = 0; i < value.length; i++) {
format = format.replace('*', value.charAt(i));
}
if (format.indexOf('*') >= 0) {
format = format.substring(0, format.indexOf('*'));
}
return format.trim();
}
In the case of winforms:
If you include the images to your resources you can do it like this, very simple and straight forward:
public Form1()
{
InitializeComponent();
button1.MouseEnter += new EventHandler(button1_MouseEnter);
button1.MouseLeave += new EventHandler(button1_MouseLeave);
}
void button1_MouseLeave(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img1));
}
void button1_MouseEnter(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
I would not recommend hardcoding image paths.
As you have altered your question ...
There is no (on)MouseOver in winforms afaik, there are MouseHover and MouseMove events, but if you change image on those, it will not change back, so the MouseEnter + MouseLeave are what you are looking for I think. Anyway, changing the image on Hover or Move :
in the constructor:
button1.MouseHover += new EventHandler(button1_MouseHover);
button1.MouseMove += new MouseEventHandler(button1_MouseMove);
void button1_MouseMove(object sender, MouseEventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
void button1_MouseHover(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
To add images to your resources: Projectproperties/resources/add/existing file
As someone else already mentioned: Benjamin Apr 10 '13 at 22:21"
It sure was easy to not pay attention and get the arguments for IsAssignableFrom backwards. I will go with GetInterfaces now :p –
Well, another way around is just to create a short extension method that fulfills, to some extent, the "most usual" way of thinking (and agreed this is a very little personal choice to make it slightly "more natural" based on one's preferences):
public static class TypeExtensions
{
public static bool IsAssignableTo(this Type type, Type assignableType)
{
return assignableType.IsAssignableFrom(type);
}
}
And why not going a bit more generic (well not sure if it is really that interesting, well I assume I'm just passing another pinch of 'syntaxing' sugar):
public static class TypeExtensions
{
public static bool IsAssignableTo(this Type type, Type assignableType)
{
return assignableType.IsAssignableFrom(type);
}
public static bool IsAssignableTo<TAssignable>(this Type type)
{
return IsAssignableTo(type, typeof(TAssignable));
}
}
I think it might be much more natural that way, but once again just a matter of very personal opinions:
var isTrue = michelleType.IsAssignableTo<IMaBelle>();
The following signature will do:
List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);
Spring Data JPA supports a large number of keywords to build a query. IN
and AND
are among them.
I tried the code provided by Ranadheer Reddy (above) and it worked great. If you’re using a company computer that has a restricted server you may need to change the SMTP port to 25 and leave your username and password blank since they will auto fill by your admin.
Originally, I tried using EASendMail from the nugent package manager, only to realize that it’s a pay for version with 30-day trial. Don’t waist your time with it unless you plan on buying it. I noticed the program ran much faster using EASendMail, but for me, free trumped fast.
Just my 2 cents worth.
Just have a line added to your crontab..
Make sure the file is executable:
chmod +x /path_to_you_file/your_file
To edit crontab file:
crontab -e
Line you have to add:
@reboot /path_to_you_file/your_file
That simple!
I had the same problem, but I solve this with the following class:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
@Configuration
@EnableWebSecurity
public class OAuthSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Bean
@Override
public AuthenticationManager authenticationManager() throws Exception {
return super.authenticationManager();
}
@Bean
public PasswordEncoder passwordEncoder() {
return NoOpPasswordEncoder.getInstance();
}
}
Not only there is no need to declare it as false
first, I would add few other improvements:
use boolean
instead of Boolean
(which can also be null
for no reason)
assign during declaration:
boolean isMatch = email1.equals(email2);
...and use final
keyword if you can:
final boolean isMatch = email1.equals(email2);
Last but not least:
if (isMatch == true)
can be expressed as:
if (isMatch)
which renders the isMatch
flag not that useful, inlining it might not hurt readability. I suggest looking for some better courses/tutorials out there...
You can use jQuery:
$(function() {
$("form input").keypress(function (e) {
if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) {
$('button[type=submit] .default').click();
return false;
} else {
return true;
}
});
});
I just encountered this problem myself and found that Ubuntu 14.04 uses Upstart instead of Systemd, so systemctl commands will not work. This changed in 15.04, so one way around this would be to update your ubuntu install.
If this is not an option for you (it's not for me right now), you need to find the Upstart command that does what you need to do.
For enable, the generic looks to be the following:
update-rc.d <service> enable
Link to Ubuntu documentation: https://wiki.ubuntu.com/SystemdForUpstartUsers
Assign the response to a value and test the attributes of it. These should tell you something useful.
response = requests.post(url,params=data,headers=headers)
response.status_code
response.text
first of all you will go to your project what you are created and next right click in your mouse and select properties in the bottom and select build in path in the left corner and add external jar file add click apply .that's it
To implement you need use Typeface go through with sample below
Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/Roboto/Roboto-Regular.ttf");
for (View view : allViews)
{
if (view instanceof TextView)
{
TextView textView = (TextView) view;
textView.setTypeface(typeface);
}
}
}
The poster is showing a dimension constrained by height in most cases he posted >>> (256x256, 1024x768, 500x400, 205x246, etc.) but fitting a 64px max height pixel dimension, typical of most landscape "photos". So my guess is he wants an image that is always 64 pixels in height. To achieve that, do the following:
<img id="photo1" style="height:64px;width:auto;" src="photo.jpg" height="64" />
This solution guarantees the images are all 64 pixels max in height and allows width to extend or shrink based on each image's aspect ratio. Setting height to 64 in the img height
attribute reserves a space in the browser's Rendertree layout as images download, so the content doesn't shift waiting for images to download. Also, the new HTML5 standard does not always honor width and height attributes. They are dimensional "hints" only, not final dimensions of the image. If in your style sheet you reset or change the image height and width, the actual values in the images attributes get reset to either your CSS value or the images native default dimensions. Setting the CSS height
to "64px" and the width
to "auto" forces width to start with the native image width (not image attribute width) and then calculate a new aspect-ratio using the CSS style for height. That gets you a new width. So the height and width "img" attributes are really not needed here and just force the browser to do extra calculations.
You need the javax.mail.jar
library.
Download it from the Java EE JavaMail GitHub page and add it to your IntelliJ project:
javax.mail.jar
File > Project Structure...
+
button (Add New Project Library)javax.mail.jar
file$timeFirst = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;
You will then be able to use the seconds to find minutes, hours, days, etc.

Sometimes it's appropriate to swallow an exception.
For UI bells and wistles, prompting the user with an error message is interuptive, and there is ussually nothing for them to do anyway. In this case, I just log it, and deal with it when it shows up in the logs.
For those who don't want to use HTML agility pack and want to get HtmlDocument from string using native .net code only here is a good article on how to convert string to HtmlDocument
Here is the code block to use
public System.Windows.Forms.HtmlDocument GetHtmlDocument(string html)
{
WebBrowser browser = new WebBrowser();
browser.ScriptErrorsSuppressed = true;
browser.DocumentText = html;
browser.Document.OpenNew(true);
browser.Document.Write(html);
browser.Refresh();
return browser.Document;
}
The following worked well for me
try {
asdf
} catch {
$string_err = $_ | Out-String
}
write-host $string_err
The result of this is the following as a string instead of an ErrorRecord object
asdf : The term 'asdf' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Instead of making the control public, you can create a property that controls its visibility:
public bool ControlIsVisible
{
get { return control.Visible; }
set { control.Visible = value; }
}
This creates a proper accessor to that control that won't expose the control's whole set of properties.

I fixed my problem by switching to the latest .Net Framework. So your target Framework sets your Security Protocol.
when you have this in Web.config
<system.web>
<httpRuntime targetFramework="4.5"/>
</system.web>
you will get this by default:
ServicePointManager.SecurityProtocol = Ssl3 | Tls
when you have this in Web.config
<system.web>
<httpRuntime targetFramework="4.6.1"/>
</system.web>
you will get this by default:
ServicePointManager.SecurityProtocol = Tls12 | Tls11 | Tls
x = int(input("press 1 for dec to oct,bin,hex \n press 2 for bin to dec,hex,oct \n press 3 for oct to bin,hex,dec \n press 4 for hex to bin,dec,oct \n"))
if x is 1:
decimal =int(input('Enter the decimal number: '))
print(bin(decimal),"in binary.")
print(oct(decimal),"in octal.")
print(hex(decimal),"in hexadecimal.")
if x is 2:
binary = input("Enter number in Binary Format: ");
decimal = int(binary, 2);
print(binary,"in Decimal =",decimal);
print(binary,"in Hexadecimal =",hex(decimal));
print(binary,"in octal =",oct(decimal));
if x is 3:
octal = input("Enter number in Octal Format: ");
decimal = int(octal, 8);
print(octal,"in Decimal =",decimal);
print(octal,"in Hexadecimal =",hex(decimal));
print(octal,"in Binary =",bin(decimal));
if x is 4:
hex = input("Enter number in hexa-decimal Format: ");
decimal = int(hex, 16);
print(hex,"in Decimal =",decimal);
print(hex,"in octal =",oct(decimal));
print(hex,"in Binary =",bin(decimal));
Make sure that in case your image is not in the dom, and you get it from local directory or server, you should wait for the image to load and just after that to draw it on the canvas.
something like that:
function drawBgImg() {
let bgImg = new Image();
bgImg.src = '/images/1.jpg';
bgImg.onload = () => {
gCtx.drawImage(bgImg, 0, 0, gElCanvas.width, gElCanvas.height);
}
}
The difference seems to be the amount of control you need over the animation.
The CATransition
approach gives you more control and therefore more things to set up, eg. the timing function. Being an object, you can store it for later, refactor to point all your animations at it to reduce duplicated code, etc.
The UIView
class methods are convenience methods for common animations, but are more limited than CATransition
. For example, there are only four possible transition types (flip left, flip right, curl up, curl down). If you wanted to do a fade in, you'd have to either dig down to CATransition's
fade transition, or set up an explicit animation of your UIView
's alpha.
Note that CATransition
on Mac OS X will let you specify an arbitrary CoreImage
filter to use as a transition, but as it stands now you can't do this on the iPhone, which lacks CoreImage
.
You can show changes that have been staged with the --cached
flag:
$ git diff --cached
In more recent versions of git, you can also use the --staged
flag (--staged
is a synonym for --cached
):
$ git diff --staged
If this JSON file won't become too big over time, you should try:
Create a JavaScript object with the table array in it
var obj = {
table: []
};
Add some data to it, for example:
obj.table.push({id: 1, square:2});
Convert it from an object to a string with JSON.stringify
var json = JSON.stringify(obj);
Use fs to write the file to disk
var fs = require('fs');
fs.writeFile('myjsonfile.json', json, 'utf8', callback);
If you want to append it, read the JSON file and convert it back to an object
fs.readFile('myjsonfile.json', 'utf8', function readFileCallback(err, data){
if (err){
console.log(err);
} else {
obj = JSON.parse(data); //now it an object
obj.table.push({id: 2, square:3}); //add some data
json = JSON.stringify(obj); //convert it back to json
fs.writeFile('myjsonfile.json', json, 'utf8', callback); // write it back
}});
This will work for data that is up to 100 MB effectively. Over this limit, you should use a database engine.
UPDATE:
Create a function which returns the current date (year+month+day) as a string. Create the file named this string + .json. the fs module has a function which can check for file existence named fs.stat(path, callback). With this, you can check if the file exists. If it exists, use the read function if it's not, use the create function. Use the date string as the path cuz the file will be named as the today date + .json. the callback will contain a stats object which will be null if the file does not exist.
Here is what I have for mine.
Essentially you are utilizing the onfocus and onblur commands in the tag to trigger the appropriate javascript. It could be as simple as:
<span><input name="login_text_password" type="text" value="Password" onfocus="this.select(); this.setAttribute('type','password');" onblur="this.select(); this.setAttribute('type','text');" /></span>
An evolved version of this basic functionality checks for and empty string and returns the password input back to the original "Password" in the event of a null textbox:
<script type="text/javascript">
function password_set_attribute() {
if (document.getElementsByName("login_text_password")[0].value.replace(/\s+/g, ' ') == "" || document.getElementsByName[0].value == null) {
document.getElementsByName("login_text_password")[0].setAttribute('type','text')
document.getElementsByName("login_text_password")[0].value = 'Password';
}
else {
document.getElementsByName("login_text_password")[0].setAttribute('type','password')
}
}
</script>
Where HTML looks like:
<span><input name="login_text_password" class="roundCorners" type="text" value="Password" onfocus="this.select(); this.setAttribute('type','password');" onblur="password_set_attribute();" /></span>
You can try using a simple library like
After installing via gradle and adding permissions initiate SmsVerifyCatcher in method like onCreate activity:
smsVerifyCatcher = new SmsVerifyCatcher(this, new OnSmsCatchListener<String>() {
@Override
public void onSmsCatch(String message) {
String code = parseCode(message);//Parse verification code
etCode.setText(code);//set code in edit text
//then you can send verification code to server
}
});
Also, override activity lifecicle methods:
@Override
protected void onStart() {
super.onStart();
smsVerifyCatcher.onStart();
}
@Override
protected void onStop() {
super.onStop();
smsVerifyCatcher.onStop();
}
/**
* need for Android 6 real time permissions
*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
smsVerifyCatcher.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
public String parseCode(String message) {
Pattern p = Pattern.compile("\\b\\d{4}\\b");
Matcher m = p.matcher(message);
String code = "";
while (m.find()) {
code = m.group(0);
}
return code;
}
You can set it as a no title bar theme in the activity's xml in the AndroidManifest
<activity
android:name=".AnActivity"
android:label="@string/a_string"
android:theme="@android:style/Theme.NoTitleBar">
</activity>
I had this problem after I installed Visual Studio 2017 and .NET Framework 4.6 on the machine that previously had Visual Studio 2010.
The problem was that after such an installation the file msvcr100_clr0400.dll from C:\Windows\System32 was overwritten with the new one with a very small size ~19 Kb, however the former one was ~800 Kb.
After I restored the file manually from another build machine cvtres.exe started working properly again.
I just had this problem for the millionth time and realized what was causing it: I created an XML file with uppercase letters in the name. All your XML filenames in /res
must match [a-z0-9\\._]
.
Also I use Tomcat GUI app (in my case: C:\tomcat\bin\Tomcat9w.bin).
Go to Java tab:
Set your Java properties, for example:

C:\tomcat\bin\bootstrap.jar;C:\tomcat\bin\tomcat-juli.jar
Java Options:

Here is the docs from the zsh man pages under STARTUP/SHUTDOWN FILES section.
Commands are first read from /etc/zshenv this cannot be overridden.
Subsequent behaviour is modified by the RCS and GLOBAL_RCS options; the
former affects all startup files, while the second only affects global
startup files (those shown here with an path starting with a /). If
one of the options is unset at any point, any subsequent startup
file(s) of the corresponding type will not be read. It is also possi-
ble for a file in $ZDOTDIR to re-enable GLOBAL_RCS. Both RCS and
GLOBAL_RCS are set by default.
Commands are then read from $ZDOTDIR/.zshenv. If the shell is a login
shell, commands are read from /etc/zprofile and then $ZDOTDIR/.zpro-
file. Then, if the shell is interactive, commands are read from
/etc/zshrc and then $ZDOTDIR/.zshrc. Finally, if the shell is a login
shell, /etc/zlogin and $ZDOTDIR/.zlogin are read.
From this we can see the order files are read is:
/etc/zshenv # Read for every shell
~/.zshenv # Read for every shell except ones started with -f
/etc/zprofile # Global config for login shells, read before zshrc
~/.zprofile # User config for login shells
/etc/zshrc # Global config for interactive shells
~/.zshrc # User config for interactive shells
/etc/zlogin # Global config for login shells, read after zshrc
~/.zlogin # User config for login shells
~/.zlogout # User config for login shells, read upon logout
/etc/zlogout # Global config for login shells, read after user logout file
You can get more information here.
Well I came up with the following solution. Keeping in mind that S and s are not duplicates. Also I have just one hard coded value.. But the code works absolutely fine.
public static String removeDuplicate(String str) {
StringBuffer rev = new StringBuffer();
rev.append(str.charAt(0));
for(int i=0; i< str.length(); i++)
{
int flag = 0;
for(int j=0; j < rev.length(); j++)
{
if(str.charAt(i) == rev.charAt(j))
{
flag = 0;
break;
}
else
{
flag = 1;
}
}
if(flag == 1)
{
rev.append(str.charAt(i));
}
}
return rev.toString();
}
Thank you. I use passing in an object as a parameter. My Android code is below
String oPerson= null;
if (CheckAddress("5556", oPerson))
{
Toast.makeText(this,
"It's Match! " + oPerson,
Toast.LENGTH_LONG).show();
}
private boolean CheckAddress(String iAddress, String oPerson)
{
Cursor cAddress = mDbHelper.getAllContacts();
String address = "";
if (cAddress.getCount() > 0) {
cAddress.moveToFirst();
while (cAddress.isAfterLast() == false) {
address = cAddress.getString(2).toString();
oPerson = cAddress.getString(1).toString();
if(iAddress.indexOf(address) != -1)
{
Toast.makeText(this,
"Person : " + oPerson,
Toast.LENGTH_LONG).show();
System.out.println(oPerson);
cAddress.close();
return true;
}
else cAddress.moveToNext();
}
}
cAddress.close();
return false;
}
The result is
Person : John
It's Match! null
Actually, "It's Match! John"

You can do something like this...
#include<iostream>
using namespace std;
//for changing values in 2D array
void myFunc(double *a,int rows,int cols){
for(int i=0;i<rows;i++){
for(int j=0;j<cols;j++){
*(a+ i*rows + j)+=10.0;
}
}
}
//for printing 2D array,similar to myFunc
void printArray(double *a,int rows,int cols){
cout<<"Printing your array...\n";
for(int i=0;i<rows;i++){
for(int j=0;j<cols;j++){
cout<<*(a+ i*rows + j)<<" ";
}
cout<<"\n";
}
}
int main(){
//declare and initialize your array
double a[2][2]={{1.5 , 2.5},{3.5 , 4.5}};
//the 1st argument is the address of the first row i.e
//the first 1D array
//the 2nd argument is the no of rows of your array
//the 3rd argument is the no of columns of your array
myFunc(a[0],2,2);
//same way as myFunc
printArray(a[0],2,2);
return 0;
}
Your output will be as follows...

Notepad++ provides 2 types of features:
Based on what you write, it seems what you want is auto-completion on function only + suggestion on arguments.
To do that, you just need to change a setting.
Settings
> Preferences...
> Auto-completion
Enable Auto-completion on each input
Function completion
and not Word completion
Function parameter hint on input
(if you have this option)On version 6.5.5 of Notepad++, I have this setting
Some documentation about auto-completion is available in Notepad++ Wiki.

With Git 2.15 (Q4 2017), "git branch
" learned "-c/-C
" to create a new branch by copying an existing one.
See commit c8b2cec (18 Jun 2017) by Ævar Arnfjörð Bjarmason (avar
).
See commit 52d59cc, commit 5463caa (18 Jun 2017) by Sahil Dua (sahildua2305
).
(Merged by Junio C Hamano -- gitster
-- in commit 3b48045, 03 Oct 2017)
branch
: add a--copy
(-c
) option to go with--move
(-m
)Add the ability to
--copy
a branch and its reflog and configuration, this uses the same underlying machinery as the--move
(-m
) option except the reflog and configuration is copied instead of being moved.This is useful for e.g. copying a topic branch to a new version, e.g.
work
towork-2
after submitting thework
topic to the list, while preserving all the tracking info and other configuration that goes with the branch, and unlike--move
keeping the other already-submitted branch around for reference.
Note: when copying a branch, you remain on your current branch.
As Junio C Hamano explains, the initial implementation of this new feature was modifying HEAD, which was not good:
When creating a new branch
B
by copying the branchA
that happens to be the current branch, it also updatesHEAD
to point at the new branch.
It probably was made this way because "git branch -c A B

If I were sitting on a blue chair, and somebody comes and repaints it to red, I would accept ending up sitting on a chair that is now red (I am also OK to stand, instead, as there no longer is my favourite blue chair).But if somebody creates a new red chair, modelling it after the blue chair I am sitting on, I do not expect to be booted off of the blue chair and ending up on sitting on the new red one.
Okay, I figured this out.
You will need html2canvas and pdfmake. You do NOT need to do any injection in your app.js to either, just include in your script tags
On the div that you want to create the PDF of, add an ID name like below:
<div id="exportthis">
In your Angular controller use the id of the div in your call to html2canvas:
change the canvas to an image using toDataURL()
Then in your docDefinition for pdfmake assign the image to the content.
The completed code in your controller will look like this:
html2canvas(document.getElementById('exportthis'), {
onrendered: function (canvas) {
var data = canvas.toDataURL();
var docDefinition = {
content: [{
image: data,
width: 500,
}]
};
pdfMake.createPdf(docDefinition).download("Score_Details.pdf");
}
});
I hope this helps someone else. Happy coding!
no_of_rows = 3 # For n by n, and even works for n by m but just give no of rows

Here's a multiple-level sort method. I'm including a snippet from an Angular JS module, but you can accomplish the same thing by scoping the sort keys objects such that your sort function has access to them. You can see the full module at Plunker.
$scope.sortMyData = function (a, b)
{
var retVal = 0, key;
for (var i = 0; i < $scope.sortKeys.length; i++)
{
if (retVal !== 0)
{
break;
}
else
{
key = $scope.sortKeys[i];
if ('asc' === key.direction)
{
retVal = (a[key.field] < b[key.field]) ? -1 : (a[key.field] > b[key.field]) ? 1 : 0;
}
else
{
retVal = (a[key.field] < b[key.field]) ? 1 : (a[key.field] > b[key.field]) ? -1 : 0;
}
}
}
return retVal;
};
If your bound property is DateTime, then all you need is
Binding={Property, StringFormat=d}
Normally you'd just stick the code in Page_Load
in your .aspx
page's code-behind.
if (someVar) {
Item1.Visible = true;
Item2.Visible = false;
} else {
Item1.Visible = false;
Item2.Visible = true;
}
This assumes you've got Item1
and Item2
laid out on the page already.
Open command prompt as administrator then run this command:
git config --system --unset credential.helper
what about a one-liner using String.split()?
String s = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
String[] split = s.split( "(?<!\".{0,255}[^\"]),|,(?![^\"].*\")" );
I came across this when upgrading from 5.8 to 6.x.
I had str_slug()
in config/cache.php
and config/session.php
.
I have changed it to Str::slug()
and the error has disappeared.
Small correction, unescape and escape are deprecated, so:
function utf8_to_b64( str ) {
return window.btoa(decodeURIComponent(encodeURIComponent(str)));
}
function b64_to_utf8( str ) {
return decodeURIComponent(encodeURIComponent(window.atob(str)));
}
function b64_to_utf8( str ) {
str = str.replace(/\s/g, '');
return decodeURIComponent(encodeURIComponent(window.atob(str)));
}
The feature you're looking for is filter
. It is capable of doing a range of image effects, including brightness:
#myimage {
filter: brightness(50%);
}
You can find a helpful article about it here: http://www.html5rocks.com/en/tutorials/filters/understanding-css/
An another: http://davidwalsh.name/css-filters
And most importantly, the W3C specs: https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/index.html
Note this is something that's only very recently coming into CSS as a feature. It is available, but a large number of browsers out there won't support it yet, and those that do support it will require a vendor prefix (ie -webkit-filter:
, -moz-filter
, etc).
It is also possible to do filter effects like this using SVG. SVG support for these effects is well established and widely supported (the CSS filter specs have been taken from the existing SVG specs)
Also note that this is not to be confused with the proprietary filter
style available in old versions of IE (although I can predict a problem with the namespace clash when the new style drops its vendor prefix).
If none of that works for you, you could still use the existing opacity
feature, but not the way you're thinking: simply create a new element with a solid dark colour, place it on top of your image, and fade it out using opacity
. The effect will be of the image behind being darkened.
Finally you can check the browser support of filter
here.
Eric answer is correct, but the problem is the fields are not grouped. Imagine you have multiple streets and cities which belong together:
<h1>First Address</h1>
<input name="street[]" value="Hauptstr" />
<input name="city[]" value="Berlin" />
<h2>Second Address</h2>
<input name="street[]" value="Wallstreet" />
<input name="city[]" value="New York" />
The outcome would be
$POST = [ 'street' => [ 'Hauptstr', 'Wallstreet'],
'city' => [ 'Berlin' , 'New York'] ];
To group them by address, I would rather recommend to use what Eric also mentioned in the comment section:
<h1>First Address</h1>
<input name="address[1][street]" value="Hauptstr" />
<input name="address[1][city]" value="Berlin" />
<h2>Second Address</h2>
<input name="address[2][street]" value="Wallstreet" />
<input name="address[2][city]" value="New York" />
The outcome would be
$POST = [ 'address' => [
1 => ['street' => 'Hauptstr', 'city' => 'Berlin'],
2 => ['street' => 'Wallstreet', 'city' => 'New York'],
]
]
Centering both horizontally and vertically
Actually, having the height and width in percents makes centering it even easier. You just offset the left and top by half of the area not occupied by the div.
So if you height is 40%, 100% - 40% = 60%. So you want 30% above and below. Then top: 30% does the trick.
See the example here: http://dabblet.com/gist/5957545
Centering only horizontally
Use inline-block. The other answer here will not work for IE 8 and below, however. You must use a CSS hack or conditional styles for that. Here is the hack version:
See the example here: http://dabblet.com/gist/5957591
.inlineblock {
display: inline-block;
zoom: 1;
display*: inline; /* ie hack */
}
By using media queries you can combine two techniques to achive the effect you want. The only complication is height. You use a nested div to switch between % width and
http://dabblet.com/gist/5957676
@media (max-width: 1000px) {
.center{}
.center-inner{left:25%;top:25%;position:absolute;width:50%;height:300px;background:#f0f;text-align:center;max-width:500px;max-height:500px;}
}
@media (min-width: 1000px) {
.center{left:50%;top:25%;position:absolute;}
.center-inner{width:500px;height:100%;margin-left:-250px;height:300px;background:#f0f;text-align:center;max-width:500px;max-height:500px;}
}
There's nothing wrong with combining an id and a class on one element, but you shouldn't need to identify it by both for one rule. If you really want to you can do:
#content.sectionA{some rules}
You don't need the div
in front of the ID as others have suggested.
In general, CSS rules specific to that element should be set with the ID, and those are going to carry a greater weight than those of just the class. Rules specified by the class would be properties that apply to multiple items that you don't want to change in multiple places anytime you need to adjust.
That boils down to this:
.sectionA{some general rules here}
#content{specific rules, and overrides for things in .sectionA}
Make sense?
This can happen if you don't attach your dataset.
I think you need the SCHEDULER_ADMIN role to see the dba_scheduler tables (however this may grant you too may rights)

This fixes the math to scale to the max size in both width and height rather than just one depending on the width and height of the original.
- (UIImage *) scaleProportionalToSize: (CGSize)size
{
float widthRatio = size.width/self.size.width;
float heightRatio = size.height/self.size.height;
if(widthRatio > heightRatio)
{
size=CGSizeMake(self.size.width*heightRatio,self.size.height*heightRatio);
} else {
size=CGSizeMake(self.size.width*widthRatio,self.size.height*widthRatio);
}
return [self scaleToSize:size];
}
First of all, a modified version of your service.
var app = angular.module('app',[]);
app.factory('ExampleService',function(){
return {
f1 : function(world){
return 'Hello' + world;
}
};
});
This returns an object, nothing to new here.
Now the way to get this from the console is
var $inj = angular.injector(['app']);
var serv = $inj.get('ExampleService');
serv.f1("World");
One of the things you were doing there earlier was to assume that the app.factory returns you the function itself or a new'ed version of it. Which is not the case. In order to get a constructor you would either have to do
app.factory('ExampleService',function(){
return function(){
this.f1 = function(world){
return 'Hello' + world;
}
};
});
This returns an ExampleService constructor which you will next have to do a 'new' on.
Or alternatively,
app.service('ExampleService',function(){
this.f1 = function(world){
return 'Hello' + world;
};
});
This returns new ExampleService() on injection.
So, strictly speaking, the "type of a variable" is always present, and can be passed around as a type parameter. For example:
val x = 5
def f[T](v: T) = v
f(x) // T is Int, the type of x
But depending on what you want to do, that won't help you. For instance, may want not to know what is the type of the variable, but to know if the type of the value is some specific type, such as this:
val x: Any = 5
def f[T](v: T) = v match {
case _: Int => "Int"
case _: String => "String"
case _ => "Unknown"
}
f(x)
Here it doesn't matter what is the type of the variable, Any
. What matters, what is checked is the type of 5
, the value. In fact, T
is useless -- you might as well have written it def f(v: Any)
instead. Also, this uses either ClassTag
or a value's Class
, which are explained below, and cannot check the type parameters of a type: you can check whether something is a List[_]
(List
of something), but not whether it is, for example, a List[Int]
or List[String]
.
Another possibility is that you want to reify the type of the variable. That is, you want to convert the type into a value, so you can store it, pass it around, etc. This involves reflection, and you'll be using either ClassTag
or a TypeTag
. For example:
val x: Any = 5
import scala.reflect.ClassTag
def f[T](v: T)(implicit ev: ClassTag[T]) = ev.toString
f(x) // returns the string "Any"
A ClassTag
will also let you use type parameters you received on match
. This won't work:
def f[A, B](a: A, b: B) = a match {
case _: B => "A is a B"
case _ => "A is not a B"
}
But this will:
val x = 'c'
val y = 5
val z: Any = 5
import scala.reflect.ClassTag
def f[A, B: ClassTag](a: A, b: B) = a match {
case _: B => "A is a B"
case _ => "A is not a B"
}
f(x, y) // A (Char) is not a B (Int)
f(x, z) // A (Char) is a B (Any)
Here I'm using the context bounds syntax, B : ClassTag
, which works just like the implicit parameter in the previous ClassTag
example, but uses an anonymous variable.
One can also get a ClassTag
from a value's Class
, like this:
val x: Any = 5
val y = 5
import scala.reflect.ClassTag
def f(a: Any, b: Any) = {
val B = ClassTag(b.getClass)
ClassTag(a.getClass) match {
case B => "a is the same class as b"
case _ => "a is not the same class as b"
}
}
f(x, y) == f(y, x) // true, a is the same class as b
A ClassTag
is limited in that it only covers the base class, but not its type parameters. That is, the ClassTag
for List[Int]
and List[String]
is the same, List
. If you need type parameters, then you must use a TypeTag
instead. A TypeTag
however, cannot be obtained from a value, nor can it be used on a pattern match, due to JVM's erasure.
Examples with TypeTag
can get quite complex -- not even comparing two type tags is not exactly simple, as can be seen below:
import scala.reflect.runtime.universe.TypeTag
def f[A, B](a: A, b: B)(implicit evA: TypeTag[A], evB: TypeTag[B]) = evA == evB
type X = Int
val x: X = 5
val y = 5
f(x, y) // false, X is not the same type as Int
Of course, there are ways to make that comparison return true, but it would require a few book chapters to really cover TypeTag
, so I'll stop here.
Finally, maybe you don't care about the type of the variable at all. Maybe you just want to know what is the class of a value, in which case the answer is rather simple:
val x = 5
x.getClass // int -- technically, an Int cannot be a class, but Scala fakes it
It would be better, however, to be more specific about what you want to accomplish, so that the answer can be more to the point.
You can change the project using the gcloud command:
gcloud config set project <your_project_name>
Have you tried:
Dim result As String
Dim sheet As Worksheet
Set sheet = ActiveWorkbook.Sheets("Data")
result = Application.WorksheetFunction.VLookup(sheet.Range("AN2"), sheet.Range("AA9:AF20"), 5, False)
I love the Shadow Wizard answer, which accually answers the question pretty nicelly. My jQuery twist on this which i use is here. http://jsfiddle.net/UJAe4/
After typing new value, the form is ready to send, just need to handle new values on the back end.
jQuery is:
(function ($)
{
$.fn.otherize = function (option_text, texts_placeholder_text) {
oSel = $(this);
option_id = oSel.attr('id') + '_other';
textbox_id = option_id + "_tb";
this.append("<option value='' id='" + option_id + "' class='otherize' >" + option_text + "</option>");
this.after("<input type='text' id='" + textbox_id + "' style='display: none; border-bottom: 1px solid black' placeholder='" + texts_placeholder_text + "'/>");
this.change(
function () {
oTbox = oSel.parent().children('#' + textbox_id);
oSel.children(':selected').hasClass('otherize') ? oTbox.show() : oTbox.hide();
});
$("#" + textbox_id).change(
function () {
$("#" + option_id).val($("#" + textbox_id).val());
});
};
}(jQuery));
So you apply this to the below html:
<form>
<select id="otherize_me">
<option value=1>option 1</option>
<option value=2>option 2</option>
<option value=3>option 3</option>
</select>
</form>
Just like this:
$(function () {
$("#otherize_me").otherize("other..", "put new option vallue here");
});
The splat and spread operators are part of ES6, the planned next version of Javascript. So far only Firefox supports them. This code works in FF16+:
var arr = ['quick', 'brown', 'lazy'];
var sprintf = function(str, ...args)
{
for (arg of args) {
str = str.replace(/%s/, arg);
}
return str;
}
sprintf.apply(null, ['The %s %s fox jumps over the %s dog.', ...arr]);
sprintf('The %s %s fox jumps over the %s dog.', 'slow', 'red', 'sleeping');
Note the awkard syntax for spread. The usual syntax of sprintf('The %s %s fox jumps over the %s dog.', ...arr);
is not yet supported. You can find an ES6 compatibility table here.
Note also the use of for...of
, another ES6 addition. Using for...in
for arrays is a bad idea.
You need make sure to start the session at the top of every PHP file where you want to use the $_SESSION
superglobal. Like this:
<?php
session_start();
echo $_SESSION['youritem'];
?>
You forgot the Session HELPER.

If you don't want to use the AWT Color.decode, then just copy the contents of the method:
int i = Integer.decode("#FFFFFF");
int[] rgb = new int[]{(i >> 16) & 0xFF, (i >> 8) & 0xFF, i & 0xFF};
Integer.decode handles the # or 0x, depending on how your string is formatted
This will give you exactly what you need (path does NOT have to exist for this to work)
DirectoryInfo di = new DirectoryInfo(@"C:\blah\..\bling");
string cleanPath = di.FullName;
I found InfoBox perfect for advanced styling.
An InfoBox behaves like a google.maps.InfoWindow, but it supports several additional properties for advanced styling. An InfoBox can also be used as a map label. An InfoBox also fires the same events as a google.maps.InfoWindow.
Include http://code.google.com/p/google-maps-utility-library-v3/source/browse/trunk/infobox/src/infobox.js in your page
As @deanchiu said it may happen when you move the whole project to another path or server.
But in my case I had no access to command line on server and running following commands BEFORE I upload my project helped me.

> php artisan config:clear
Configuring Identity to your existing project is not hard thing. You must install some NuGet package and do some small configuration.
First install these NuGet packages with Package Manager Console:
PM> Install-Package Microsoft.AspNet.Identity.Owin
PM> Install-Package Microsoft.AspNet.Identity.EntityFramework
PM> Install-Package Microsoft.Owin.Host.SystemWeb
Add a user class and with IdentityUser
inheritance:
public class AppUser : IdentityUser
{
//add your custom properties which have not included in IdentityUser before
public string MyExtraProperty { get; set; }
}
Do same thing for role:
public class AppRole : IdentityRole
{
public AppRole() : base() { }
public AppRole(string name) : base(name) { }
// extra properties here
}
Change your DbContext
parent from DbContext
to IdentityDbContext<AppUser>
like this:
public class MyDbContext : IdentityDbContext<AppUser>
{
// Other part of codes still same
// You don't need to add AppUser and AppRole
// since automatically added by inheriting form IdentityDbContext<AppUser>
}
If you use the same connection string and enabled migration, EF will create necessary tables for you.
Optionally, you could extend UserManager
to add your desired configuration and customization:
public class AppUserManager : UserManager<AppUser>
{
public AppUserManager(IUserStore<AppUser> store)
: base(store)
{
}
// this method is called by Owin therefore this is the best place to configure your User Manager
public static AppUserManager Create(
IdentityFactoryOptions<AppUserManager> options, IOwinContext context)
{
var manager = new AppUserManager(
new UserStore<AppUser>(context.Get<MyDbContext>()));
// optionally configure your manager
// ...
return manager;
}
}
Since Identity is based on OWIN you need to configure OWIN too:
Add a class to App_Start
folder (or anywhere else if you want). This class is used by OWIN. This will be your startup class.
namespace MyAppNamespace
{
public class IdentityConfig
{
public void Configuration(IAppBuilder app)
{
app.CreatePerOwinContext(() => new MyDbContext());
app.CreatePerOwinContext<AppUserManager>(AppUserManager.Create);
app.CreatePerOwinContext<RoleManager<AppRole>>((options, context) =>
new RoleManager<AppRole>(
new RoleStore<AppRole>(context.Get<MyDbContext>())));
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Home/Login"),
});
}
}
}
Almost done just add this line of code to your web.config
file so OWIN could find your startup class.
<appSettings>
<!-- other setting here -->
<add key="owin:AppStartup" value="MyAppNamespace.IdentityConfig" />
</appSettings>
Now in entire project you could use Identity just like any new project had already installed by VS. Consider login action for example
[HttpPost]
public ActionResult Login(LoginViewModel login)
{
if (ModelState.IsValid)
{
var userManager = HttpContext.GetOwinContext().GetUserManager<AppUserManager>();
var authManager = HttpContext.GetOwinContext().Authentication;
AppUser user = userManager.Find(login.UserName, login.Password);
if (user != null)
{
var ident = userManager.CreateIdentity(user,
DefaultAuthenticationTypes.ApplicationCookie);
//use the instance that has been created.
authManager.SignIn(
new AuthenticationProperties { IsPersistent = false }, ident);
return Redirect(login.ReturnUrl ?? Url.Action("Index", "Home"));
}
}
ModelState.AddModelError("", "Invalid username or password");
return View(login);
}
You could make roles and add to your users:
public ActionResult CreateRole(string roleName)
{
var roleManager=HttpContext.GetOwinContext().GetUserManager<RoleManager<AppRole>>();
if (!roleManager.RoleExists(roleName))
roleManager.Create(new AppRole(roleName));
// rest of code
}
You could also add a role to a user, like this:
UserManager.AddToRole(UserManager.FindByName("username").Id, "roleName");
By using Authorize
you could guard your actions or controllers:
[Authorize]
public ActionResult MySecretAction() {}
or
[Authorize(Roles = "Admin")]]
public ActionResult MySecretAction() {}
You can also install additional packages and configure them to meet your requirement like Microsoft.Owin.Security.Facebook
or whichever you want.
Note: Don't forget to add relevant namespaces to your files:
using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;
You could also see my other answers like this and this for advanced use of Identity.

You need to define a valid type of SelectParameter. This MSDN article describes the various types and how to use them.
Just thought I would expand on this a bit.
If you perform a MYSQLI SELECT query that returns 0 results, it returns FALSE.
However, if you get this error and you have written your own MYSQLI Query function, then you can also get this error if the query you are running is not a select but an update. An update query will return either TRUE or FALSE. So if you just assume that any non false result will have records returned, then you will trip up when you run an update or anything other than select.
The easiest solution, once you have checked that its not false, is to first check that the result of the query is an object.
$sqlResult = $connection->query($sql);
if (!$sqlResult)
{
...
}
else if (is_object($sqlResult))
{
$sqlRowCount = $sqlResult->num_rows;
}
else
{
$sqlRowCount = 0;
}

FETCH_HEAD
is a short-lived ref, to keep track of what has just been fetched from the remote repository. git pull
first invokes git fetch
, in normal cases fetching a branch from the remote; FETCH_HEAD
points to the tip of this branch (it stores the SHA1 of the commit, just as branches do). git pull
then invokes git merge
, merging FETCH_HEAD
into the current branch.
The result is exactly what you'd expect: the commit at the tip of the appropriate remote branch is merged into the commit at the tip of your current branch.
This is a bit like doing git fetch
without arguments (or git remote update
), updating all your remote branches, then running git merge origin/<branch>

internally instead to refer to whatever single ref was fetched, instead of needing to name things.
Error messages don't get any clearer than this:
"Scripts may close only the windows that were opened by it."
If your script did not initiate opening the window (with something like window.open), then the script in that window is not allowed to close it. Its a security to prevent a website taking control of your browser and closing windows.

Other ways in jQuery
var foo = $("#foo");
foo.children().remove();
//or
$("*", foo ).remove();
//or
foo.html("");
//or
foo.empty();
There aren't a lot of them because they would be in competition with JFreeChart, and it's awesome. You can get documentation and examples by downloading the developer's guide. There are also tons of free online tutorials if you search for them.
You need to store it in a String
variable first before displaying it like so:
String Txt = TxtBoxContent.getText();
System.out.println(Txt);
This is how I did for my CRUDManager class
initialized in Angular controller, which later passed over to jQuery button-click event defined outside the controller:
In Angular Controller:
// Note that I can even pass over the $scope to my CRUDManager's constructor.
var crudManager = new CRUDManager($scope, contextData, opMode);
crudManager.initialize()
.then(() => {
crudManager.dataBind();
$scope.crudManager = crudManager;
$scope.$apply();
})
.catch(error => {
alert(error);
});
In jQuery Save button click event outside the controller:
$(document).on("click", "#ElementWithNgControllerDefined #btnSave", function () {
var ngScope = angular.element($("#ElementWithNgControllerDefined")).scope();
var crudManager = ngScope.crudManager;
crudManager.saveData()
.then(finalData => {
alert("Successfully saved!");
})
.catch(error => {
alert("Failed to save.");
});
});
This is particularly important and useful when your jQuery events need to be placed OUTSIDE OF CONTROLLER in order to prevent it from firing twice.
For large files, what I did was read the file line by line and read each line into an array. Then, once the array reached a certain size, append it to a new file.
for line in open("file.txt", "r"):
list.append(line)
if len(list) == 1000000:
output.writelines(list)
del list[:]
The best way in your particular case would just be to change your two criteria to one criterion:
dists[abs(dists - r - dr/2.) <= dr/2.]
It only creates one boolean array, and in my opinion is easier to read because it says, is dist
within a dr
or r
? (Though I'd redefine r
to be the center of your region of interest instead of the beginning, so r = r + dr/2.
) But that doesn't answer your question.
The answer to your question:
You don't actually need where
if you're just trying to filter out the elements of dists
that don't fit your criteria:
dists[(dists >= r) & (dists <= r+dr)]
Because the &
will give you an elementwise and
(the parentheses are necessary).
Or, if you do want to use where
for some reason, you can do:
dists[(np.where((dists >= r) & (dists <= r + dr)))]
Why:
The reason it doesn't work is because np.where
returns a list of indices, not a boolean array. You're trying to get and
between two lists of numbers, which of course doesn't have the True
/False
values that you expect. If a
and b
are both True
values, then a and b
returns b
. So saying something like [0,1,2] and [2,3,4]
will just give you [2,3,4]
. Here it is in action:
In [230]: dists = np.arange(0,10,.5)
In [231]: r = 5
In [232]: dr = 1
In [233]: np.where(dists >= r)
Out[233]: (array([10, 11, 12, 13, 14, 15, 16, 17, 18, 19]),)
In [234]: np.where(dists <= r+dr)
Out[234]: (array([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]),)
In [235]: np.where(dists >= r) and np.where(dists <= r+dr)
Out[235]: (array([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]),)
What you were expecting to compare was simply the boolean array, for example
In [236]: dists >= r
Out[236]:
array([False, False, False, False, False, False, False, False, False,
False, True, True, True, True, True, True, True, True,
True, True], dtype=bool)
In [237]: dists <= r + dr
Out[237]:
array([ True, True, True, True, True, True, True, True, True,
True, True, True, True, False, False, False, False, False,
False, False], dtype=bool)
In [238]: (dists >= r) & (dists <= r + dr)
Out[238]:
array([False, False, False, False, False, False, False, False, False,
False, True, True, True, False, False, False, False, False,
False, False], dtype=bool)
Now you can call np.where
on the combined boolean array:
In [239]: np.where((dists >= r) & (dists <= r + dr))
Out[239]: (array([10, 11, 12]),)
In [240]: dists[np.where((dists >= r) & (dists <= r + dr))]
Out[240]: array([ 5. , 5.5, 6. ])
Or simply index the original array with the boolean array using fancy indexing
In [241]: dists[(dists >= r) & (dists <= r + dr)]
Out[241]: array([ 5. , 5.5, 6. ])
Since nobody so far felt fit to point out why what you're trying doesn't work:
NA == NA
doesn't return TRUE
, it returns NA
(since comparing to undefined values should yield an undefined result). apply
on an atomic vector. You can't use apply
to loop over the elements in a column. a$x
, which is just the column (an atomic vector).I'd fix up 3. to get to a$x[is.na(a$x)] <- 0
I've built a module that makes in-memory pagination incredibly simple.
It allows you to paginate by simply replacing ng-repeat
with dir-paginate
, specifying the items per page as a piped filter, and then dropping the controls wherever you like in the form of a single directive, <dir-pagination-controls>
To take the original example asked by Tomarto, it would look like this:
<ul class='phones'>
<li class='thumbnail' dir-paginate='phone in phones | filter:searchBar | orderBy:orderProp | limitTo:limit | itemsPerPage: limit'>
<a href='#/phones/{{phone.id}}' class='thumb'><img ng-src='{{phone.imageUrl}}'></a>
<a href='#/phones/{{phone.id}}'>{{phone.name}}</a>
<p>{{phone.snippet}}</p>
</li>
</ul>
<dir-pagination-controls></dir-pagination-controls>
There is no need for any special pagination code in your controller. It's all handled internally by the module.
I found I can make the match when I input a hard-coded non-breaking space (U+00A0) by typing Alt+0160 on Windows between the two quotes...
//table[@id='TableID']//td[text()=' ']
worked for me with the special char.
From what I understood, the XPath 1.0 standard doesn't handle escaping Unicode chars. There seems to be functions for that in XPath 2.0 but it looks like Firefox doesn't support it (or I misunderstood something). So you have to do with local codepage. Ugly, I know.
Actually, it looks like the standard is relying on the programming language using XPath to provide the correct Unicode escape sequence... So, somehow, I did the right thing.
For Firefox:
Thread.sleep() could work in most cases, but usually if you're waiting, you are actually waiting for a particular condition or state to occur. Thread.sleep() does not guarantee that whatever you're waiting for has actually happened.
If you are waiting on a rest request for example maybe it usually return in 5 seconds, but if you set your sleep for 5 seconds the day your request comes back in 10 seconds your test is going to fail.
To remedy this JayWay has a great utility called Awatility which is perfect for ensuring that a specific condition occurs before you move on.
It has a nice fluent api as well
await().until(() ->
{
return yourConditionIsMet();
});
Indeed there is.
chmod a+x
is relative to the current state and just sets the x
flag. So a 640 file becomes 751 (or 750?), a 644 file becomes 755.
chmod 755
, however, sets the mask as written: rwxr-xr-x
, no matter how it was before. It is equivalent to chmod u=rwx,go=rx
.
As mentioned, the C compiler will add padding for alignment requirements. These requirements often have to do with the memory subsystem. Some types of computers can only access memory lined up to some 'nice' value, like 4 bytes. This is often the same as the word length. Thus, the C compiler may align fields in your structure to this value to make them easier to access (e.g., 4 byte values should be 4 byte aligned) Further, it may pad the bottom of the structure to line up data which follows the structure. I believe there are other reasons as well. More info can be found at this wikipedia page.
Have you heard of "SQuirreL SQL Client"?
You'll want to use a udf as below
from pyspark.sql.types import IntegerType
from pyspark.sql.functions import udf
def func(fruit1, fruit2):
if fruit1 == None or fruit2 == None:
return 3
if fruit1 == fruit2:
return 1
return 0
func_udf = udf(func, IntegerType())
df = df.withColumn('new_column',func_udf(df['fruit1'], df['fruit2']))
An alternative to the usual methods is to hook into the drawing of the view.
OnPreDrawListener
is called many times when displaying a view, so there is no specific iteration where your view has valid measured width or height. This requires that you continually verify (view.getMeasuredWidth() <= 0
) or set a limit to the number of times you check for a measuredWidth
greater than zero.
There is also a chance that the view will never be drawn, which may indicate other problems with your code.
final View view = [ACQUIRE REFERENCE]; // Must be declared final for inner class
ViewTreeObserver viewTreeObserver = view.getViewTreeObserver();
viewTreeObserver.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
@Override
public boolean onPreDraw() {
if (view.getMeasuredWidth() > 0) {
view.getViewTreeObserver().removeOnPreDrawListener(this);
int width = view.getMeasuredWidth();
int height = view.getMeasuredHeight();
//Do something with width and height here!
}
return true; // Continue with the draw pass, as not to stop it
}
});
SET ANSI_NULLS ON
IT Returns all values including null values in the table
SET ANSI_NULLS off
it Ends when columns contains null values
The cool thing about the new Google Recaptcha is that the validation is now completely encapsulated in the widget. That means, that the widget will take care of asking questions, validating responses all the way till it determines that a user is actually a human, only then you get a g-recaptcha-response value.
But that does not keep your site safe from HTTP client request forgery.
Anyone with HTTP POST knowledge could put random data inside of the g-recaptcha-response form field, and foll your site to make it think that this field was provided by the google widget. So you have to validate this token.
In human speech it would be like,
Validating the response is really easy. Just make a GET Request to
And replace the response_string with the value that you earlier got by the g-recaptcha-response field.
You will get a JSON Response with a success field.
More information here: https://developers.google.com/recaptcha/docs/verify
Edit: It's actually a POST, as per documentation here.
Though the above answers have covered, I have just tried to add minute detail s which i see missing. The reason behind them(The Why).

dependencyOne.methodOne();
dependencyTwo.methodTwo();
...
return sampleResponse;

One way to speed things up is to explicitly perform multiple inserts or copy's within a transaction (say 1000). Postgres's default behavior is to commit after each statement, so by batching the commits, you can avoid some overhead. As the guide in Daniel's answer says, you may have to disable autocommit for this to work. Also note the comment at the bottom that suggests increasing the size of the wal_buffers to 16 MB may also help.
I wrote a small gist which I think can be very helpful to anybody seeking a solution to that problem: external link
What it does is it adds target="_blank"
attributes to anchor elements that would link to a domain different than the current one.
You can patch it up to whatever you see fit.
You can plot several columns at once by supplying a list of column names to the plot
's y
argument.
df.plot(x="X", y=["A", "B", "C"], kind="bar")
This will produce a graph where bars are sitting next to each other.
In order to have them overlapping, you would need to call plot
several times, and supplying the axes to plot to as an argument ax
to the plot.
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])
ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")
plt.show()
Here is an alternate approach. It is more intuitive.
One key aspect I feel some of the answers did not take into account, which I point out for posterity, is apply() lets you do row calculations easily, but only for matrix (all numeric) data
operations on columns are possible still for dataframes:
as.data.frame(lapply(df, myFunctionForColumn()))
To operate on rows, we make the transpose first.
tdf<-as.data.frame(t(df))
as.data.frame(lapply(tdf, myFunctionForRow()))
The downside is that I believe R will make a copy of your data table. Which could be a memory issue. (This is truly sad, because it is programmatically simple for tdf to just be an iterator to the original df, thus saving memory, but R does not allow pointer or iterator referencing.)
Also, a related question, is how to operate on each individual cell in a dataframe.
newdf <- as.data.frame(lapply(df, function(x) {sapply(x, myFunctionForEachCell()}))
check web.xml file maybe servletContextlistener not doing well . in my case i added servletContextlistener and let him an empty and gave me the same error, i tried to delete it from project files but it still in web.xml file .finally i delete it from the web.xml and save the file . run the project and it stated successfully
For completness sake I included what my issue was and how I solved it:
If your like me and have httphandlers via web.config and you have redirects from your global.asax.cs (maybe in Session_Start() ) like in my case you get this error if your startup project does not have a reference defined which points to the target where your httphandler is pointing!! (but you wont get build errors, just runtime errors)
So:
Cheers.

Use the error
handler like this:
$('#image_id').error(function() {
alert('Image does not exist !!');
});
If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert is displayed:
Update:
I think using:
$.ajax({url:'somefile.dat',type:'HEAD',error:do_something});
would be enough to check for a 404.
More Readings:
Update 2:
Your code should be like this:
$(this).error(function() {
alert('Image does not exist !!');
});
No need for these lines and that won't check if the remote file exists anyway:
var imgcheck = imgsrc.width;
if (imgcheck==0) {
alert("You have a zero size image");
} else {
//execute the rest of code here
}

I had/have this problem too. In my case, none of the explanations applied:
Until I found out that once I accessed the windows folder via another (linux) computer, git worked without complaints. It must have something to do with the git version I use from my normal debian buster computer: git 1.2.20 is giving me the 'unable to write new index' error, whereas from a ubuntu fuzzy virtualbox (git 1.2.2) adds the file without problems.
If anyone can't seem to get there .bash_profile
file to take any new Paths AND you have other commands in that file (like alias commands) then try moving the PATH statements to the top of the file.
That is the only thing that worked for me. The reason it worked was because I had some typos in my alias commands and apparently this file throws an error and exits if it runs into a problem. So that is why my PATH statements weren't being run. Moving it to the top just let it run first.
Just call moment as a function without any arguments:
moment()
For timezone information with moment, look at the moment-timezone
package: http://momentjs.com/timezone/
Beside above solutions, there is a more "COMMON" way - directly delete the largest space consumer from Linux machine. You can follow the below steps:
Using ls -lart to list out hidden folder also, normally jenkin installation is placed in .jenkins/ folder
[xxxxx ~]$ ls -lart drwxrwxr-x 12 xxxx 4096 Feb 8 02:08 .jenkins/
Use df -h
to show Disk space in high level
du -sh ./*/
to list out total memory for each subfolder in current path.
du -a /etc/ | sort -n -r | head -n 10
will list top 10 directories eating disk space in /etc/
Normally ./job/ folder or ./workspace/ folder can be the largest folder. Please go inside and delete base on you need (DO NOT delete entire folder).
rm -rf theFolderToDelete
HTML: text/html

XHTML: application/xhtml+xml
, or only if following HTML compatbility guidelines, text/html

There are also many other media types based around XML, for example application/rss+xml

(For unregistered x-

Here's the simplest solution i came up with, we get the value of the input created by material-ui textField :
create(e) {
e.preventDefault();
let name = this.refs.name.input.value;
alert(name);
}
constructor(){
super();
this.create = this.create.bind(this);
}
render() {
return (
<form>
<TextField ref="name" hintText="" floatingLabelText="Your name" /><br/>
<RaisedButton label="Create" onClick={this.create} primary={true} />
</form>
)}
hope this helps.
I use double quotes because I have been doing so for years in most languages (C++, Java, VB…) except Bash, because I also use double quotes in normal text and because I'm using a (modified) non-English keyboard where both characters require the shift key.
XmlTextWriter.WriteString()
does the escaping.
Had a similar issue while installing "Lua" in OS X using homebrew. I guess it could be useful for other users facing similar issue in homebrew.
On running the command:
$ brew install lua
The command returned an error:
Error: /usr/local/opt/lua is not a valid keg
(in general the error can be of /usr/local/opt/ is not a valid keg
FIXED it by deleting the file/directory it is referring to, i.e., deleting the "/usr/local/opt/lua" file.
root-user # rm -rf /usr/local/opt/lua
And then running the brew install command returned success.
echo N | copy /-y $(SolutionDir)SomeDir $(OutDir)
EDIT: Okay, so you don't want your local time (which isn't Australia) to contribute to the result, but instead the Australian time zone. Your existing code should be absolutely fine then, although Sydney is currently UTC+11, not UTC+10.. Short but complete test app:
import java.util.*;
import java.text.*;
public class Test {
public static void main(String[] args) throws InterruptedException {
Date date = new Date(1318386508000L);
DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
String formatted = format.format(date);
System.out.println(formatted);
format.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));
formatted = format.format(date);
System.out.println(formatted);
}
}
Output:
12/10/2011 02:28:28
12/10/2011 13:28:28
I would also suggest you start using Joda Time which is simply a much nicer date/time API...
EDIT: Note that if your system doesn't know about the Australia/Sydney
time zone, it would show UTC. For example, if I change the code about to use TimeZone.getTimeZone("blah/blah")
it will show the UTC value twice. I suggest you print TimeZone.getTimeZone("Australia/Sydney").getDisplayName()
and see what it says... and check your code for typos too :)
This is the best way IMO. No need for properties, or readonly:
public static class Constants
{
public const string SomeConstant = "Some value";
}
May I suggest using the fish bone operator?
for (auto x = std::end(a); x != std::begin(a); )
{
std::cout <<*--x<< ' ';
}

I am just answering here with the formatted version of the final sql I needed based on Bob Jarvis answer as posted in my comment above:
select n1.name, n1.author_id, cast(count_1 as numeric)/total_count
from (select id, name, author_id, count(1) as count_1
from names
group by id, name, author_id) n1
inner join (select author_id, count(1) as total_count
from names
group by author_id) n2
on (n2.author_id = n1.author_id)
Write the following function/methos using Java:
protected boolean isElementPresent(By by){
try{
driver.findElement(by);
return true;
}
catch(NoSuchElementException e){
return false;
}
}
Call the method with appropriate parameter during assertion.
curl
sends POST requests with the default content type of application/x-www-form-urlencoded
. If you want to send a JSON request, you will have to specify the correct content type header:
$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"
But that will only work if the server accepts json input. The .json
at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.
The reason you get a 401
and not some other error is probably because the server can't extract the auth_token
from your request.
Watcher with the deep option didn't work for me.
Instead, I use updated() lifecycle hook which gets executed everytime the component's data changes. Just use it like you do with mounted().
mounted() {
/* to be executed when mounted */
},
updated() {
console.log(this.$route)

For your reference, visit the documentation.
I don't thinks that possible with a vanilla collection without storing the key values in an independent array.
The easiest alternative to do this is to add a reference to the Microsoft Scripting Runtime & use a more capable Dictionary instead:
Dim dict As Dictionary
Set dict = New Dictionary
dict.Add "key1", "value1"
dict.Add "key2", "value2"
Dim key As Variant
For Each key In dict.Keys
Debug.Print "Key: " & key, "Value: " & dict.Item(key)

I like the extension method approach so you don't have to pass through all possible parameters.
However using Regular expressions can be quite tricky (and somewhat slower) so I used XDocument
instead:
public static MvcHtmlString SetDisabled(this MvcHtmlString html, bool isDisabled)
{
var xDocument = XDocument.Parse(html.ToHtmlString());
if (!(xDocument.FirstNode is XElement element))
{
return html;
}
element.SetAttributeValue("disabled", isDisabled ? "disabled" : null);
return MvcHtmlString.Create(element.ToString());
}
Use the extension method like this:
@Html.EditorFor(m => m.MyProperty).SetDisabled(Model.ExpireDate == null)
This will give total number of days including today in the current month.
select day(getDate())
For example, lets say we want to display only the first 10 items of an array, we could do this using the SlicePipe like so:
<ul>
<li *ngFor="let item of items | slice:0:10">
{{ item }}
</li>
</ul>
I don't think zip
returns a list. zip
returns a generator. You have got to do list(zip(a, b))
to get a list of tuples.
x = [1, 2, 3]
y = [4, 5, 6]
zipped = zip(x, y)
list(zipped)
Try killing the pythonw process from the Task Manager (if Windows) if nothing else works.
This is working in ISPConfig too. In website list get inside a domain, click to Options tab, add these lines: ;
ProxyPass / http://localhost:8181/
ProxyPassReverse / http://localhost:8181/
Then go to website and wolaa :) This is working HTTPS protocol too.
Use beginUpdates
and endUpdates
to insert a new cell when the button clicked.
As @vadian said in comment,
begin/endUpdates
has no effect for a single insert/delete/move operation
First of all, append data in your tableview array
Yourarray.append([labeltext])
Then update your table and insert a new row
// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()
This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()
Swift 3.0
tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()
Objective-C
[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];
After trying to find a solution that handled every circumstance (options for animating the scroll, padding around the object once it scrolls into view, works even in obscure circumstances such as in an iframe), I finally ended up writing my own solution to this. Since it seems to work when many other solutions failed, I thought I'd share it:
function scrollIntoViewIfNeeded($target, options) {
var options = options ? options : {},
$win = $($target[0].ownerDocument.defaultView), //get the window object of the $target, don't use "window" because the element could possibly be in a different iframe than the one calling the function
$container = options.$container ? options.$container : $win,
padding = options.padding ? options.padding : 20,
elemTop = $target.offset().top,
elemHeight = $target.outerHeight(),
containerTop = $container.scrollTop(),
//Everything past this point is used only to get the container's visible height, which is needed to do this accurately
containerHeight = $container.outerHeight(),
winTop = $win.scrollTop(),
winBot = winTop + $win.height(),
containerVisibleTop = containerTop < winTop ? winTop : containerTop,
containerVisibleBottom = containerTop + containerHeight > winBot ? winBot : containerTop + containerHeight,
containerVisibleHeight = containerVisibleBottom - containerVisibleTop;
if (elemTop < containerTop) {
//scroll up
if (options.instant) {
$container.scrollTop(elemTop - padding);
} else {
$container.animate({scrollTop: elemTop - padding}, options.animationOptions);
}
} else if (elemTop + elemHeight > containerTop + containerVisibleHeight) {
//scroll down
if (options.instant) {
$container.scrollTop(elemTop + elemHeight - containerVisibleHeight + padding);
} else {
$container.animate({scrollTop: elemTop + elemHeight - containerVisibleHeight + padding}, options.animationOptions);
}
}
}
$target
is a jQuery object containing the object you wish to scroll into view if needed.
options
(optional) can contain the following options passed in an object:
options.$container
- a jQuery object pointing to the containing element of $target (in other words, the element in the dom with the scrollbars). Defaults to the window that contains the $target element and is smart enough to select an iframe window. Remember to include the $ in the property name.
options.padding
- the padding in pixels to add above or below the object when it is scrolled into view. This way it is not right against the edge of the window. Defaults to 20.
options.instant
- if set to true, jQuery animate will not be used and the scroll will instantly pop to the correct location. Defaults to false.
options.animationOptions
- any jQuery options you wish to pass to the jQuery animate function (see http://api.jquery.com/animate/). With this, you can change the duration of the animation or have a callback function executed when the scrolling is complete. This only works if options.instant
is set to false. If you need to have an instant animation but with a callback, set options.animationOptions.duration = 0
instead of using options.instant = true
.
I had a similar problem and solved it by combining the answers above
class FeedPost extends React.Component {
constructor(props) {
...
this.handleLayoutChange = this.handleLayoutChange.bind(this);
}
handleLayoutChange() {
this.feedPost.measure( (fx, fy, width, height, px, py) => {
console.log('Component width is: ' + width)
console.log('Component height is: ' + height)
console.log('X offset to page: ' + px)
console.log('Y offset to page: ' + py)
})
}
render {
return(
<View onLayout={(event) => {this.handleLayoutChange(event) }}
ref={view => { this.feedPost = view; }} >
...
Now I can see the position of my feedPost element in the logs:

08-24 11:15:36.838 3727 27838 I ReactNativeJS: Component height is: 206

what is polymorphism?
From java tutorial
The dictionary definition of polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. This principle can also be applied to object-oriented programming and languages like the Java language. Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class.
By considering the examples and definition, overriding should be accepted answer.
Regarding your second query:
IF you had a abstract base class that defined a method with no implementation, and you defined that method in the sub class, is that still overridding?
It should be called overriding.
Have a look at this example to understand different types of overriding.

You can do this, you just need to circumvent the launcher.
In %appdata%\.minecraft\bin
(or ~/.minecraft/bin
on unixy systems), there is a minecraft.jar file. This is the actual game - the launcher runs this.
Invoke it like so:
java -Xms512m -Xmx1g -Djava.library.path=natives/ -cp "minecraft.jar;lwjgl.jar;lwjgl_util.jar" net.minecraft.client.Minecraft <username> <sessionID>
Set the working directory to .minecraft/bin
.
To get the session ID, POST (request this page):
https://login.minecraft.net?user=<username>&password=<password>&version=13
You'll get a response like this:
1343825972000:deprecated:SirCmpwn:7ae9007b9909de05ea58e94199a33b30c310c69c:dba0c48e1c584963b9e93a038a66bb98
The fourth field is the session ID. More details here. Read those details, this answer is outdated
Here's an example of logging in to minecraft.net in C#.
You can use a lambda with an input parameter, like so:
.Returns((string myval) => { return myval; });
Or slightly more readable:
.Returns<string>(x => x);
In GitHub markdown <ins>
text</ins>
works just fine.
Browse the repository with Firefox and inspect the element with Firebug. Under the NET tab, you can check the Header of the page. It will have something like:
Server: Apache/2.2.14 (Win32) DAV/2 SVN/1.X.X
Hehe, curious. I think this is an "intentianal bug", so to speak.
The underlying reason is how the Integer class is written. Basically, parseInt is "optimized" for positive numbers. When it parses the string, it builds the result cumulatively, but negated. Then it flips the sign of the end-result.
Example:
66 = 0x42
parsed like:
4*(-1) = -4
-4 * 16 = -64 (hex 4 parsed)
-64 - 2 = -66 (hex 2 parsed)
return -66 * (-1) = 66
Now, let's look at your example FFFF8000
16*(-1) = -16 (first F parsed)
-16*16 = -256
-256 - 16 = -272 (second F parsed)
-272 * 16 = -4352
-4352 - 16 = -4368 (third F parsed)
-4352 * 16 = -69888
-69888 - 16 = -69904 (forth F parsed)
-69904 * 16 = -1118464
-1118464 - 8 = -1118472 (8 parsed)
-1118464 * 16 = -17895552
-17895552 - 0 = -17895552 (first 0 parsed)
Here it blows up since -17895552 < -Integer.MAX_VALUE / 16 (-134217728).
Attempting to execute the next logical step in the chain (-17895552 * 16)
would cause an integer overflow error.
Edit (addition): in order for the parseInt() to work "consistently" for -Integer.MAX_VALUE <= n <= Integer.MAX_VALUE, they would have had to implement logic to "rotate" when reaching -Integer.MAX_VALUE in the cumulative result, starting over at the max-end of the integer range and continuing downwards from there. Why they did not do this, one would have to ask Josh Bloch or whoever implemented it in the first place. It might just be an optimization.
However,
Hex=Integer.toHexString(Integer.MAX_VALUE);
System.out.println(Hex);
System.out.println(Integer.parseInt(Hex.toUpperCase(), 16));
works just fine, for just this reason. In the sourcee for Integer you can find this comment.
// Accumulating negatively avoids surprises near MAX_VALUE
If you are receiving that error even after creating a new user and assigning them the database previledges, then the one last thing to look at is to check if the users have been assigned the preiveledges in the database.
To do this log into to your mysql(This is presumably its the application that has restricted access to the database but you as a root can be ablr to access your database table via mysql -u user -p)
commands to apply
mysql -u root -p
password: (provide your database credentials)
on successful login
type
use mysql;
from this point check each users priveledges if it is enabled from the db table as follows
select User,Grant_priv,Host from db;
if the values of the Grant_priv col for the created user is N update that value to Y with the following command
UPDATE db SET Grant_priv = "Y" WHERE User= "your user";
with that now try accessing the app and making a transaction with the database.
The new tests you wrote (directly or indirectly) use classes that log using Log4j.
Log4J needs to be configured for this logging to work properly.
Put a log4j.properties (or log4j.xml) file in the root of your test classpath.
It should have some basic configuration such as
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
# An alternative logging format:
# log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1} - %m%n
An appender outputs to the console by default, but you can also explicitly set the target like this:
log4j.appender.A1.Target=System.out
This will redirect all output in a nice format to the console. More info can be found here in the Log4J manual,
Log4J Logging will then be properly configured and this warning will disappear.
Here's how I managed to do something similar to this inside a <footer>
element:
<div class="content-wrapper">

</div>
CSS:
.content-wrapper
{
margin: 0 auto;
max-width: 1216px;
}
Try and see if this works:
I know that question is a bit old but
pipenv --venv
/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU
rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU
Here you go! Ready for Xcode 8 and Swift 3.
import UIKit
let mString = "This is a String that contains something to search."
let stringToSearchUpperCase = "String"
let stringToSearchLowerCase = "string"
mString.contains(stringToSearchUpperCase) //true
mString.contains(stringToSearchLowerCase) //false
mString.lowercased().contains(stringToSearchUpperCase) //false
mString.lowercased().contains(stringToSearchLowerCase) //true
I have done this quite a bit in PyQt and it works very well. Qt has extensive support for images, fonts, styles, etc and all of those can be written out to pdf documents.
For C++11, vector.data()
will do the trick.
I like the idea from Jakub Jirutka to use Spring Expression Language. If you don't want to add another library/dependency (assuming that you already use Spring), here is a simplified implementation of his idea.
The constraint:
@Constraint(validatedBy=ExpressionAssertValidator.class)
@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface ExpressionAssert {
String message() default "expression must evaluate to true";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
String value();
}
The validator:
public class ExpressionAssertValidator implements ConstraintValidator<ExpressionAssert, Object> {
private Expression exp;
public void initialize(ExpressionAssert annotation) {
ExpressionParser parser = new SpelExpressionParser();
exp = parser.parseExpression(annotation.value());
}
public boolean isValid(Object value, ConstraintValidatorContext context) {
return exp.getValue(value, Boolean.class);
}
}
Apply like this:
@ExpressionAssert(value="pass == passVerify", message="passwords must be same")
public class MyBean {
@Size(min=6, max=50)
private String pass;
private String passVerify;
}

to make sure the scripting engine will recognize your script as a vbscript.
Windows/DOS batch files doesn't require escaping \
like *nix.
You can still use "C:\Users\guest\Desktop\123\MyScript.vbs"
, but this requires the user has *.vbs
associated to wscript
.
I am going to suggest something here because I recently faced the same issue and I tried every possible thing in the answers but nothing worked. I was getting errors like
ERROR: The process with PID 23908 could not be terminated. Reason: There is no running instance of the task.
using command prompt. Power shell wasn't helpful either. it would simply execute the commands and no response with process still running.
Until I decided to delete the associated '.exe' file. Since the file was active, windows would not allow the deletion, but in that warning window it gave me the name of the process which was holding up the task I wanted to kill. I was able to kill the original task and thus the buggy process.
It is definitely worth a try if none of the solutions works out.
Two ways.
i. You can put it in ApplicationController and add the filters in the controller
class ApplicationController < ActionController::Base def filter_method end end class FirstController < ApplicationController before_filter :filter_method end class SecondController < ApplicationController before_filter :filter_method end
But the problem here is that this method will be added to all the controllers since all of them extend from application controller
ii. Create a parent controller and define it there
class ParentController < ApplicationController def filter_method end end class FirstController < ParentController before_filter :filter_method end class SecondController < ParentController before_filter :filter_method end
I have named it as parent controller but you can come up with a name that fits your situation properly.
You can also define the filter method in a module and include it in the controllers where you need the filter
For the best practice - use style="display:"
it will work every where..
The combination of find
and ls
works well for
The solution:
find . -name "my-pattern" -print0 |
xargs -r -0 ls -1 -t |
head -1
Let's break it down:
With find
we can match all interesting files like this:
find . -name "my-pattern" ...
then using -print0
we can pass all filenames safely to the ls
like this:
find . -name "my-pattern" -print0 | xargs -r -0 ls -1 -t
additional find
search parameters and patterns can be added here
find . -name "my-pattern" ... -print0 | xargs -r -0 ls -1 -t
ls -t
will sort files by modification time (newest first) and print it one at a line. You can use -c
to sort by creation time. Note: this will break with filenames containing newlines.
Finally head -1
gets us the first file in the sorted list.
Note: xargs
use system limits to the size of the argument list. If this size exceeds, xargs
will call ls
multiple times. This will break the sorting and probably also the final output. Run
xargs --show-limits
to check the limits on you system.
Note 2: use find . -maxdepth 1 -name "my-pattern" -print0
if you don't want to search files through subfolders.
Note 3: As pointed out by @starfry - -r
argument for xargs
is preventing the call of ls -1 -t
, if no files were matched by the find
. Thank you for the suggesion.
I think you need to push a revert commit. So pull
from github again, including the commit you want to revert, then use git revert
and push the result.
If you don't care about other people's clones of your github repository being broken, you can also delete and recreate the master branch on github after your reset
: git push origin :master
.
You could check the position of the div using $(div).position()
and check if the left and top margin properties are less than 0 :
if($(div).position().left < 0 && $(div).position().top < 0){
alert("off screen");
}
Way to clean out any old versions of gems.
sudo gem cleanup
If you just want to see a list of what would be removed you can use:
sudo gem cleanup -d
You can also cleanup just a specific gem by specifying its name:
sudo gem cleanup gemname
for remove specific version like 1.1.9 only
gem uninstall gemname --version 1.1.9
If you still facing some exception to install gem, like:
invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /home/rails/.rvm/gems/ruby-2.1.1@project/cache/nokogiri-1.6.6.2.gem
the, you can remove it from cache:
rm /home/rails/.rvm/gems/ruby-2.1.1@project/cache/nokogiri-1.6.6.2.gem

The main
method is the entry point of a Java application.
Specifically?when the Java Virtual Machine is told to run an application by specifying its class (by using the java
application launcher), it will look for the main
method with the signature of public static void main(String[])
.
From Sun's java
command page:
The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.
The method must be declared public and static, it must not return any value, and it must accept a
String
array as a parameter. The method declaration must look like the following:public static void main(String args[])
For additional resources on how an Java application is executed, please refer to the following sources:
The run
method is the entry point for a new Thread
or an class implementing the Runnable
interface. It is not called by the Java Virutal Machine when it is started up by the java
command.
As a Thread
or Runnable
itself cannot be run directly by the Java Virtual Machine, so it must be invoked by the Thread.start()
method. This can be accomplished by instantiating a Thread
and calling its start
method in the main
method of the application:
public class MyRunnable implements Runnable
{
public void run()
{
System.out.println("Hello World!");
}
public static void main(String[] args)
{
new Thread(new MyRunnable()).start();
}
}
For more information and an example of how to start a subclass of Thread
or a class implementing Runnable
, see Defining and Starting a Thread from the Java Tutorials.
The init
method is the first method called in an Applet or JApplet.
When an applet is loaded by the Java plugin of a browser or by an applet viewer, it will first call the Applet.init
method. Any initializations that are required to use the applet should be executed here. After the init
method is complete, the start
method is called.
For more information about when the init
method of an applet is called, please read about the lifecycle of an applet at The Life Cycle of an Applet from the Java Tutorials.
See also: How to Make Applets from the Java Tutorial.
I tried just about everything in the comments and it didn't work. So I did gacutil /i "path to my dll"
from Powershell and it worked.
Also remember the trick of pressing Shift when you right-click on a file in Windows Explorer to get the option of Copy path.
you can use:
<?php
$css = file_get_contents('CSS/main.css');
echo $css;
?>
and assuming that css file doesn't have it already, wrap the above in:
<style type="text/css">
...
</style>
Try something like this:
Dim windowsShell
Dim regValue
Set windowsShell = CreateObject("WScript.Shell")
regValue = windowsShell.RegRead("someRegKey")
try/catch is scripted syntax. So any time you are using declarative syntax to use something from scripted in general you can do so by enclosing the scripted syntax in the scripts block in a declarative pipeline. So your try/catch should go inside stage >steps >script.
This holds true for any other scripted pipeline syntax you would like to use in a declarative pipeline as well.
The isConnected
method won't help, it will return true
even if the remote side has closed the socket. Try this:
public class MyServer {
public static final int PORT = 12345;
public static void main(String[] args) throws IOException, InterruptedException {
ServerSocket ss = ServerSocketFactory.getDefault().createServerSocket(PORT);
Socket s = ss.accept();
Thread.sleep(5000);
ss.close();
s.close();
}
}
public class MyClient {
public static void main(String[] args) throws IOException, InterruptedException {
Socket s = SocketFactory.getDefault().createSocket("localhost", MyServer.PORT);
System.out.println(" connected: " + s.isConnected());
Thread.sleep(10000);
System.out.println(" connected: " + s.isConnected());
}
}
Start the server, start the client. You'll see that it prints "connected: true" twice, even though the socket is closed the second time.
The only way to really find out is by reading (you'll get -1 as return value) or writing (an IOException
(broken pipe) will be thrown) on the associated Input/OutputStreams.
Actually it has been worked but
just try this.
take the value /\s/g into a string variable like
String a = /\s/g;
str = str.replaceAll(a,"X");
You are calling:
JSON.parse(scatterSeries)
But when you defined scatterSeries
, you said:
var scatterSeries = [];
When you try to parse it as JSON it is converted to a string (""
), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.
scatterSeries
is not JSON. Do not try to parse it as JSON.
data
is not JSON either (getJSON
will parse it as JSON automatically).
ch
is JSON … but shouldn't be. You should just create a plain object in the first place:
var ch = {
"name": "graphe1",
"items": data.results[1]
};
scatterSeries.push(ch);
In short, for what you are doing, you shouldn't have JSON.parse
anywhere in your code. The only place it should be is in the jQuery library itself.
I had to:
\\127.0.0.1\SSRSFileShare
I already found it:
SELECT grantee, privilege_type
FROM information_schema.role_table_grants
WHERE table_name='mytable'
html
<div class="text-lg-right text-center">
center in xs and right in lg devices
</div>
Try running this code in your script.
document.getElementById("dummy").remove();
And it will hopefully remove the element/button.
If you're trying to grab a range with a dynamically generated string, then you just have to build the string like this:
Range(firstcol & firstrow & ":" & secondcol & secondrow).Select
this.setState({abc: {xyz: 'new value'}});
will NOT work, as state.abc
will be entirely overwritten, not merged.
This works for me:
this.setState((previousState) => {
previousState.abc.xyz = 'blurg';
return previousState;
});
Unless I'm reading the docs wrong, Facebook recommends the above format. https://facebook.github.io/react/docs/component-api.html
Additionally, I guess the most direct way without mutating state is to directly copy by using the ES6 spread/rest operator:
const newState = { ...this.state.abc }; // deconstruct state.abc into a new object-- effectively making a copy
newState.xyz = 'blurg';
this.setState(newState);
Your .eslintrc.json should contain the text below.
This way ESLint knows about your global variables.
{
"env": {
"browser": true,
"node": true
}
}
Incase their is local uncommitted changes and avoid merge conflict while pulling.
git stash save
git pull
git stash pop
checked
attribute is a boolean value so "checked"
value of other "string"
except boolean false
converts to true
.
Any string value will be true. Also presence of attribute make it true:
<input type="checkbox" checked>
You can make it uncheked only making boolean change in DOM using JS.
So the answer is: they are equal.
It dipends on which distribution you are in general but... You have to install the php-curl module and then enable it on php.ini like you did in windows. Once you are done remember to restart apache demon!
Just Remove the the Workstation Components from Add/Remove Programs - SQL Server 2005. Removing Workstation Components, SQL Server 2008 installation goes well.
Here is an example from my HOW TO Matlab page:
close all; clear all;
img = imread('lena.tif','tif');
imagesc(img)
img = fftshift(img(:,:,2));
F = fft2(img);
figure;
imagesc(100*log(1+abs(fftshift(F)))); colormap(gray);
title('magnitude spectrum');
figure;
imagesc(angle(F)); colormap(gray);
title('phase spectrum');
This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.
ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say
img = imread('ngc6543a.jpg');
and it will work. I used an older version of Matlab to make the above example and just copied it here.
On the scaling factor
When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c
value in the equation
s = c log(1+r)
There is no known way to pre detrmine this scale that I know. Just need to
try different values to get on you like. I used 100
in the above example.
GitHub has (since) developed a nice modular text editor called Atom (based on Chromium and uses Node.js modules for packages).
A default preinstalled package Markdown Preview lets you display your preview in a separate tab using Ctrl + Shift + M.
I haven't tested its full syntax, but since it's coming from GitHub, I'd be highly surprised if the preview's syntax was different from theirs (fenced blocks using ~~~
work).
Now, while it's not technically command-line based, it uses Node.js and outputs to a DOM-based renderer, which might help anyone trying to render GitHub syntax-based HTML on a Node.js-based webserver, or just edit her/his README.md offline.
