Option One:
This message is often due to an IIS 7 config problem. If you are used to creating a virtual directory pointing to the folder where your service resides, that no longer works. Now, you need to use the "Create Application..." option instead.
Other Options:
Use the (ngModelChange)
event to detect changes on the model
Please try this simple function
var NanValue = function (entry) {
if(entry=="NaN") {
return 0.00;
} else {
return entry;
}
}
I think move
would probably be the closest standard cursor value for what you're doing:
move
Indicates something is to be moved.
SELECT LAST(row_name) FROM table_name
you can use this function to download file from base64.
function downloadPDF(pdf) {
const linkSource = `data:application/pdf;base64,${pdf}`;
const downloadLink = document.createElement("a");
const fileName = "abc.pdf";
downloadLink.href = linkSource;
downloadLink.download = fileName;
downloadLink.click();}
This code will made an anchor tag with href and download file. if you want to use button then you can call click method on your button click.
i hope this will help of you thanks
As an alternate you can use reactive forms. Here is an example: https://stackblitz.com/edit/angular-pqb2xx
Template
<form [formGroup]="mainForm" ng-submit="submitForm()">
Global Price: <input type="number" formControlName="globalPrice">
<button type="button" [disabled]="mainForm.get('globalPrice').value === null" (click)="applyPriceToAll()">Apply to all</button>
<table border formArrayName="orderLines">
<ng-container *ngFor="let orderLine of orderLines let i=index" [formGroupName]="i">
<tr>
<td>{{orderLine.time | date}}</td>
<td>{{orderLine.quantity}}</td>
<td><input formControlName="price" type="number"></td>
</tr>
</ng-container>
</table>
</form>
Component
import { Component } from '@angular/core';
import { FormGroup, FormControl, FormArray } from '@angular/forms';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
name = 'Angular 6';
mainForm: FormGroup;
orderLines = [
{price: 10, time: new Date(), quantity: 2},
{price: 20, time: new Date(), quantity: 3},
{price: 30, time: new Date(), quantity: 3},
{price: 40, time: new Date(), quantity: 5}
]
constructor() {
this.mainForm = this.getForm();
}
getForm(): FormGroup {
return new FormGroup({
globalPrice: new FormControl(),
orderLines: new FormArray(this.orderLines.map(this.getFormGroupForLine))
})
}
getFormGroupForLine(orderLine: any): FormGroup {
return new FormGroup({
price: new FormControl(orderLine.price)
})
}
applyPriceToAll() {
const formLines = this.mainForm.get('orderLines') as FormArray;
const globalPrice = this.mainForm.get('globalPrice').value;
formLines.controls.forEach(control => control.get('price').setValue(globalPrice));
// optionally recheck value and validity without emit event.
}
submitForm() {
}
}
you could use an onchange event to trigger a validation and then you can display a toast if this is enough for you
Maybe you mean like this? I like to make an object and use Format-Table:
> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table
Name Age Info
---- --- ----
Joe 32 something about him
This will put all objects you have in the array in columns according to their properties.
Tip: Using -auto
sizes the table better
> $array | Format-Table -Auto
Name Age Info
---- --- ----
Joe 32 something about him
You can also specify which properties you want in the table. Just separate each property name with a comma:
> $array | Format-Table Name, Age -Auto
Name Age
---- ---
Joe 32

First of all you use here two strings: "" marks a string it may be ""
-empty "s"
- string of lenght 1 or "aaa"
string of lenght 3, while '' marks chars . In order to be able to do String str = "a" + "aaa" + 'a'
you must use method Character.toString(char c) as @Thomas Keene said so an example would be String str = "a" + "aaa" + Character.toString('a')
I had same problem. After some digging why my MainActivity is called with intent without data I realized that my LAUNCHER activity (as in Manifest) is SplashActivity. There I found the message data and forwarded them to MainActivity. Works like sharm. I beleive this can help someone.
Thanks for all another answers.
The only way is passing the host information as environment when you create a container
run --env <key>=<value>
In the version of .NET I am using you also have to do this:
System.Net.ServicePointManager.Expect100Continue = false;
If you don't, the HttpWebRequest
class will automatically add the Expect:100-continue
request header which fouls everything up.
Also I learned the hard way that you have to have the right number of dashes. whatever you say is the "boundary" in the Content-Type
header has to be preceded by two dashes
--THEBOUNDARY
and at the end
--THEBOUNDARY--
exactly as it does in the example code. If your boundary is a lot of dashes followed by a number then this mistake won't be obvious by looking at the http request in a proxy server
I think the simplest solution, rather than making the body
element partially transparent, would be to add an extra div
to hold the background, and change the opacity there, instead.
So you would add a div
like:
<div id="background"></div>
And move your body
element's background CSS to it, as well as some additional positioning properties, like this:
#background {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-image: url('images/background.jpg');
background-repeat: no-repeat;
background-attachment: fixed;
background-size: 100%;
opacity: 0.8;
filter:alpha(opacity=80);
}
Here's an example: http://jsfiddle.net/nbVg4/4/
Before answering, let's add some background, explaining what this HEAD
is.
First of all what is HEAD?
HEAD
is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD
at any given time (excluding git worktree
).
The content of HEAD
is stored inside .git/HEAD
and it contains the 40 bytes SHA-1 of the current commit.
detached HEAD
If you are not on the latest commit - meaning that HEAD
is pointing to a prior commit in history it's called detached HEAD
.
On the command line, it will look like this - SHA-1 instead of the branch name since the HEAD
is not pointing to the tip of the current branch:
git checkout
git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back
This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.
# Checkout a given commit.
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>
# Create a new branch forked to the given commit
git checkout -b <branch name>
git reflog
You can always use the reflog
as well.
git reflog
will display any change which updated the HEAD
and checking out the desired reflog entry will set the HEAD
back to this commit.
Every time the HEAD is modified there will be a new entry in the reflog
git reflog
git checkout HEAD@{...}
This will get you back to your desired commit
git reset --hard <commit_id>
"Move" your HEAD back to the desired commit.
# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32
# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.
git rebase --no-autostash
as well.git revert <sha-1>
"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.
# Add a new commit with the undo of the original one.
# The <sha-1> can be any commit(s) or commit range
git revert <sha-1>
This schema illustrates which command does what.
As you can see there, reset && checkout
modify the HEAD
.
Ah I think a understand now. Have a look if this really is what you want:
$(".start").keyup(function(){
$(this).closest('tr').find("input").each(function() {
alert(this.value)
});
});
This will give you all input values of a row.
Update:
To get the value of not all elements you can use :not()
:
$(this).closest('tr').find("input:not([name^=desc][name^=phone])").each(function() {
alert(this.value)
});
Actually I am not 100% sure whether it works this way, maybe you have to use two not
s instead of this one combining both conditions.
It can also be retrieved from the registry:
Get-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters' |
% { $_.'NV HostName', $_.'NV Domain' -join '.' }
Depending on how it will be used, you can either do this with two maps Map<K1, V>
and Map<K2, V>
or with two maps Map<K1, V>
and Map<K2, K1>
. If one of the keys is more permanent than the other, the second option may make more sense.
To use list-view inside Scroll-view you can follow these steps which worked for me :
1) Create NonScrollListView java file that disable the default scrolling property of list-view. and code is below
package your-package-structure;
import android.content.Context;
import android.util.AttributeSet;
import android.view.ViewGroup;
import android.widget.ListView;
public class NonScrollListView extends ListView {
public NonScrollListView(Context context) {
super(context);
}
public NonScrollListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
}
2) Now create xml file which which has NestedScrollView
and inside this use NonScrollListView
for listing your items. This will make your entire screen to scroll with all the views.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<ViewFlipper
android:id="@+id/v_flipper"
android:layout_width="match_parent"
android:layout_height="130dp">
</ViewFlipper>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="SHOP"
android:textSize="15dp"
android:textStyle="bold"
android:gravity="center"
android:padding="5dp"
android:layout_marginTop="15dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"/>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginBottom="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:background="#ddd"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1"
>
<com.abc.xyz.NonScrollListView
android:id="@+id/listview"
android:divider="@null"
android:layout_width="match_parent"
android:layout_marginBottom="10dp"
android:layout_height="match_parent"
android:padding="8dp">
</com.abc.xyz.NonScrollListView>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="bottom">
<include layout="@layout/footer" />
</LinearLayout>
</LinearLayout>
3) Now in java class i.e, home.java define NonScrollListView
instead of Listview
.
package comabc.xyz.landscapeapp;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.support.v4.app.FragmentTransaction;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.Toast;
import android.widget.Toolbar;
import android.widget.ViewFlipper;
public class home extends Fragment { int pos = 0; ViewFlipper v_flipper;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_home, container, false);
return view;
}
@Override
public void onViewCreated(@NonNull final View view, @Nullable Bundle savedInstanceState) {
NonScrollListView listView = (NonScrollListView) view.findViewById(R.id.listview);
customAdapter customAdapter = new customAdapter(getActivity());
listView.setAdapter(customAdapter);
listView.setFocusable(false);
customAdapter.notifyDataSetChanged();
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("listview click", "onItemClick: ");
/* FragmentTransaction fr = getFragmentManager().beginTransaction().replace(R.id.fragment_container, new productdisplay());
fr.putExtra("Position", position);
fr.addToBackStack("tag");
fr.commit();*/
Intent intent = new Intent(getActivity(), productdisplay.class);
intent.putExtra("Position", position);
startActivity(intent);
}
});
//image slider
int images[] = {R.drawable.slide1, R.drawable.slide2, R.drawable.slide3};
v_flipper = view.findViewById(R.id.v_flipper);
for (int image : images) {
flipperImages(image);
}
}
private void flipperImages(int image) {
ImageView imageView = new ImageView(getActivity());
imageView.setBackgroundResource(image);
v_flipper.addView(imageView);
v_flipper.setFlipInterval(4000);
v_flipper.setAutoStart(true);
v_flipper.setInAnimation(getActivity(), android.R.anim.slide_in_left);
v_flipper.setOutAnimation(getActivity(), android.R.anim.slide_out_right);
}
}
Note: I used Fragments
here.
Try using entity codes such as 
for CR, 

for LF, and 	
for TAB.
For example:
<div title="1)	A
2)	B">Hover Me</div>
_x000D_
The reason it's hard to just kill a thread is because the language designers want to avoid the following problem: your thread takes a lock, and then you kill it before it can release it. Now anyone who needs that lock will get stuck.
What you have to do is use some global variable to tell the thread to stop. You have to manually, in your thread code, check that global variable and return if you see it indicates you should stop.
By initializing the min/max values to their extreme opposite, you avoid any edge cases of values in the input: Either one of min/max is in fact one of those values (in the case where the input consists of only one of those values), or the correct min/max will be found.
It should be noted that primitive types must have a value. If you used Objects (ie Integer
), you could initialize value to null
and handle that special case for the first comparison, but that creates extra (needless) code. However, by using these values, the loop code doesn't need to worry about the edge case of the first comparison.
Another alternative is to set both initial values to the first value of the input array (never a problem - see below) and iterate from the 2nd element onward, since this is the only correct state of min/max after one iteration. You could iterate from the 1st element too - it would make no difference, other than doing one extra (needless) iteration over the first element.
The only sane way of dealing with inout of size zero is simple: throw an IllegalArgumentException
, because min/max is undefined in this case.
One additional thing I would like to mention that some of the answers may have missed is the downside to having both ETags
and Expires/Cache-control
in your headers.
Depending on your needs it may just add extra bytes in your headers which may increase packets which means more TCP overhead. Again, you should see if the overhead of having both things in your headers is necessary or will it just add extra weight in your requests which reduces performance.
You can read more about it on this excellent blog post by Kyle Simpson: http://calendar.perfplanet.com/2010/bloated-request-response-headers/
It is possibly to use the flag -o,--offline "Work offline"
to prevent that.
Like this:
maven compile -o
If you aren't interested in keeping the unstaged changes (especially if the staged changes are new files), I found this handy:
git diff | git apply --reverse
You could try:
$j('div.contextualError.ckgcellphone').css('display')
CALL common.php
<style>
.ddsmoothmenu ul li{float: left; padding: 0 20px;}
.ddsmoothmenu ul li a{display: block;
padding: 40px 15px 20px 15px;
color: #4b4b4b;
font-size: 13px;
font-family: 'Open Sans', Arial, sans-serif;
text-align: right;
text-transform: uppercase;
margin-left: 1px; color: #fff; background: #000;}
.current .test{ background: #2767A3; color: #fff;}
</style>
<div class="span8 ddsmoothmenu">
<!-- // Dropdown Menu // -->
<ul id="dropdown-menu" class="fixed">
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'index.php'){echo 'current'; }else { echo ''; } ?>"><a href="index.php" class="test">Home <i>::</i> <span>welcome</span></a></li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'about.php'){echo 'current'; }else { echo ''; } ?>"><a href="about.php" class="test">About us <i>::</i> <span>Who we are</span></a></li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'course.php'){echo 'current'; }else { echo ''; } ?>"><a href="course.php">Our Courses <i>::</i> <span>What we do</span></a></li>
</ul><!-- end #dropdown-menu -->
</div><!-- end .span8 -->
add each page
<?php include('common.php'); ?>
You also need to annotate the method with @JavascriptInterface if your targetSdkVersion is >= 17 - because there is new security requirements in SDK 17, i.e. all javascript methods must be annotated with @JavascriptInterface. Otherwise you will see error like: Uncaught TypeError: Object [object Object] has no method 'processHTML' at null:1
You should be able to use mustache.js, if it doesn't work send me the issues and I'll get it fixed because I'm about to be using them in node.js anyway.

I know that it works without a DOM because a bunch of CouchDB standalone apps are using it in a Spidermonkey view server.
I have used jQuery AJAX to make AJAX requests.
Check the following code:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#call').click(function ()
{
$.ajax({
type: "post",
url: "testme", //this is my servlet
data: "input=" +$('#ip').val()+"&output="+$('#op').val(),
success: function(msg){
$('#output').append(msg);
}
});
});
});
</script>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
input:<input id="ip" type="text" name="" value="" /><br></br>
output:<input id="op" type="text" name="" value="" /><br></br>
<input type="button" value="Call Servlet" name="Call Servlet" id="call"/>
<div id="output"></div>
</body>
This is how you call an instance method on the Controller:
@{
((HomeController)this.ViewContext.Controller).Method1();
}
This is how you call a static method in any class
@{
SomeClass.Method();
}
This will work assuming the method is public and visible to the view.
To set custom error message for HTML 5 validation use,
oninvalid="this.setCustomValidity('Your custom message goes here.')"
and to remove this message when user enters valid data use,
onkeyup="setCustomValidity('')"
Hope this works for you. Enjoy ;)
The usual trick is to make the image itself part of a link instead of a button. Then, you bind the "click" event with a custom handler.
Frameworks like Jquery-UI or Bootstrap does this out of the box. Using one of them may ease a lot the whole application conception by the way.
This cannot work because ppCombined
is a collection of objects in memory and you cannot join a set of data in the database with another set of data that is in memory. You can try instead to extract the filtered items personProtocol
of the ppCombined
collection in memory after you have retrieved the other properties from the database:
var persons = db.Favorites
.Where(f => f.userId == userId)
.Join(db.Person, f => f.personId, p => p.personId, (f, p) =>
new // anonymous object
{
personId = p.personId,
addressId = p.addressId,
favoriteId = f.favoriteId,
})
.AsEnumerable() // database query ends here, the rest is a query in memory
.Select(x =>
new PersonDTO
{
personId = x.personId,
addressId = x.addressId,
favoriteId = x.favoriteId,
personProtocol = ppCombined
.Where(p => p.personId == x.personId)
.Select(p => new PersonProtocol
{
personProtocolId = p.personProtocolId,
activateDt = p.activateDt,
personId = p.personId
})
.ToList()
});
ServicePointManager.ServerCertificateValidationCallback isn't supported in .Net Core.
Current situation is that it will be a a new ServerCertificateCustomValidationCallback method for the upcoming 4.1.* System.Net.Http contract (HttpClient). .NET Core team are finalizing the 4.1 contract now. You can read about this in here on github
You can try out the pre-release version of System.Net.Http 4.1 by using the sources directly here in CoreFx or on the MYGET feed: https://dotnet.myget.org/gallery/dotnet-core
Current WinHttpHandler.ServerCertificateCustomValidationCallback definition on Github
You can declare it yourself quite easily:
interface StringConstructor {
format: (formatString: string, ...replacement: any[]) => string;
}
String.format('','');
This is assuming that String.format is defined elsewhere. e.g. in Microsoft Ajax Toolkit : http://www.asp.net/ajaxlibrary/Reference.String-format-Function.ashx
There is also a plot.background
option in addition to panel.background
:
df <- data.frame(y=d,x=1)
p <- ggplot(df) + stat_boxplot(aes(x = x,y=y))
p <- p + opts(
panel.background = theme_rect(fill = "transparent",colour = NA), # or theme_blank()
panel.grid.minor = theme_blank(),
panel.grid.major = theme_blank(),
plot.background = theme_rect(fill = "transparent",colour = NA)
)
#returns white background
png('tr_tst2.png',width=300,height=300,units="px",bg = "transparent")
print(p)
dev.off()
For some reason, the uploaded image is displaying differently than on my computer, so I've omitted it. But for me, I get a plot with an entirely gray background except for the box part of the boxplot which is still white. That can be changed using the fill aesthetic in the boxplot geom as well, I believe.
Edit
ggplot2 has since been updated and the opts()
function has been deprecated. Currently, you would use theme()
instead of opts()
and element_rect()
instead of theme_rect()
, etc.
Calling erase will invalidate iterators, you could use:
void erase(std::vector<int>& myNumbers_in, int number_in)
{
std::vector<int>::iterator iter = myNumbers_in.begin();
while (iter != myNumbers_in.end())
{
if (*iter == number_in)
{
iter = myNumbers_in.erase(iter);
}
else
{
++iter;
}
}
}
Or you could use std::remove_if together with a functor and std::vector::erase:
struct Eraser
{
Eraser(int number_in) : number_in(number_in) {}
int number_in;
bool operator()(int i) const
{
return i == number_in;
}
};
std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), Eraser(number_in)), myNumbers.end());
Instead of writing your own functor in this case you could use std::remove:
std::vector<int> myNumbers;
myNumbers.erase(std::remove(myNumbers.begin(), myNumbers.end(), number_in), myNumbers.end());
In C++11 you could use a lambda instead of a functor:
std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), [number_in](int number){ return number == number_in; }), myNumbers.end());
In C++17 std::experimental::erase and std::experimental::erase_if are also available, in C++20 these are (finally) renamed to std::erase and std::erase_if (note: in Visual Studio 2019 you'll need to change your C++ language version to the latest experimental version for support):
std::vector<int> myNumbers;
std::erase_if(myNumbers, Eraser(number_in)); // or use lambda
or:
std::vector<int> myNumbers;
std::erase(myNumbers, number_in);
var myTestApp = angular.module("myTestApp", []);
myTestApp.controller("myTestController", function($scope, $window) {
$window.onload = function() {
alert("is called on page load.");
};
});
The latest version of the official mysql docker image allows you to import data on startup. Here is my docker-compose.yml
data:
build: docker/data/.
mysql:
image: mysql
ports:
- "3307:3306"
environment:
MYSQL_ROOT_PASSWORD: 1234
volumes:
- ./docker/data:/docker-entrypoint-initdb.d
volumes_from:
- data
Here, I have my data-dump.sql under docker/data
which is relative to the folder the docker-compose is running from. I am mounting that sql file into this directory /docker-entrypoint-initdb.d
on the container.
If you are interested to see how this works, have a look at their docker-entrypoint.sh
in GitHub. They have added this block to allow importing data
echo
for f in /docker-entrypoint-initdb.d/*; do
case "$f" in
*.sh) echo "$0: running $f"; . "$f" ;;
*.sql) echo "$0: running $f"; "${mysql[@]}" < "$f" && echo ;;
*) echo "$0: ignoring $f" ;;
esac
echo
done
An additional note, if you want the data to be persisted even after the mysql container is stopped and removed, you need to have a separate data container as you see in the docker-compose.yml. The contents of the data container Dockerfile are very simple.
FROM n3ziniuka5/ubuntu-oracle-jdk:14.04-JDK8
VOLUME /var/lib/mysql

The data container doesn't even have to be in start state for persistence.
window.top.location.href = "http://www.example.com";
Will redirect the top most parent Iframe.
window.parent.location.href = "http://www.example.com";
Will redirect the parent iframe.
You might find it useful to lookup the classes on oracle. Eg:
http://download.oracle.com/javase/1.4.2/docs/api/javax/swing/JFrame.html
There you can see that JFrame extends JComponent and JContainer.
JComponent is a a basic object that can be drawn, JContainer extends this so that you can add components to it. JPanel and JFrame both extend JComponent as you can add things to them. JFrame provides a window, whereas JPanel is just a panel that goes inside a window. If that makes sense.
Above, Abhishek mentions the command line differences specified in two URLS:
PhoneGap: http://docs.phonegap.com/en/edge/guide_cli_index.md.html
Cordova: http://cordova.apache.org/docs/en/3.0.0/guide_cli_index.md.html#The%20Command-line%20Interface
One thing to point out is that, as of this post, the phonegap one looks to be almost the same as the cordova one, and is probably not an accurate image of the command line option differences. As such, I installed both on my system so I could look at the differences.
These are just a few of them. Hopefully they are brought more in sync sometime. If anyone has better information, please tell me.
I guess my point is that the phonegap CLI documention mentioned quite often is not really for the phonegap CLI, but for the cordova CLI, at this time. Please tell me if I am missing something. Thanks.
The -Contains
operator doesn't do substring comparisons and the match must be on a complete string and is used to search collections.
From the documentation you linked to:
-Contains Description: Containment operator. Tells whether a collection of reference values includes a single test value.
In the example you provided you're working with a collection containing just one string item.
If you read the documentation you linked to you'll see an example that demonstrates this behaviour:
Examples:
PS C:\> "abc", "def" -Contains "def"
True
PS C:\> "Windows", "PowerShell" -Contains "Shell"
False #Not an exact match
I think what you want is the -Match
operator:
"12-18" -Match "-"
Which returns True
.
Important: As pointed out in the comments and in the linked documentation, it should be noted that the -Match
operator uses regular expressions to perform text matching.
I was having a similar issue. Being a total noob at bootstrap, it turned out i was missing the glyphicon keyword before the icon name.
<span class="glyphicon-search"></span>
Should have been
<span class="glyphicon glyphicon-search"></span>
Even though Logger.log()
is technically the correct way to output something to the console, it has a few annoyances:
Logger.log(playerArray)
, and then after debugging you'd probably want to remove Logger.log(playerArray)
, hence an additional 1-2 more steps.Instead, whenever I want to debug something I add breakpoints (click on line number) and press the Debug button (bug icon). Breakpoints work well when you are assigning something to a variable, but not so well when you are initiating a variable and want to peek inside of it at a later point, which is similar to what the op is trying to do. In this case, I would force a break condition by entering "x" (x marks the spot!) to throw a run-time error:
Compare with viewing Logs:
The Debug console contains more information and is a lot easier to read than the Logs overlay. One minor benefit with this method is that you never have to worry about polluting your code with a bunch of logging commands if keeping clean code is your thing. Even if you enter "x", you are forced to remember to remove it as part of the debugging process or else your code won't run (built-in cleanup measure, yay).

There are two kinds of cell reference, and it's really valuable to understand them well.
One is relative reference, which is what you get when you just type the cell: A5
. This reference will be adjusted when you paste or fill the formula into other cells.
The other is absolute reference, and you get this by adding dollar signs to the cell reference: $A$5
. This cell reference will not change when pasted or filled.
A cool but rarely used feature is that row and column within a single cell reference may be independent: $A5
and A$5
. This comes in handy for producing things like multiplication tables from a single formula.
This works for me.

In a single database - yes:
USE your_database
SELECT name FROM sys.tables
Getting all tables across all databases - only with a hack.... see this SO question for several approaches how to do that: How do I list all tables in all databases in SQL Server in a single result set?
Currently, it's very easy to achieve this. You only need to add the following code to your pages:
<a href="whatsapp://send?text=<<HERE GOES THE URL ENCODED TEXT YOU WANT TO SHARE>>" data-action="share/whatsapp/share">Share via Whatsapp</a>
And that's it. No Javascript needed, nothing else needed. Of course you can style it as you want and include a nice Whatsapp icon.

We had the same issue, using Plesk Onyx 17. Instead of messing up with rights etc., solution was to add nginx user into psacln group, in which all the other domain owners (users) were:
usermod -aG psacln nginx
Now nginx has rights to access .htaccess or any other file necessary to properly show the content.
On the other hand, also make sure that Apache is in psaserv group, to serve static content:
usermod -aG psaserv apache
And don't forget to restart both Apache and Nginx in Plesk after! (and reload pages with Ctrl-F5)
It can be caused by:
Please, post your code.
you can simply do this..
<img src={"http://img.example.com/test/" + this.props.url +"/1.jpg"}/>
$_ is an variable which iterates over each object/element passed from the previous | (pipe).
My approach is based on Nicks' answer and hopefully is a bit more usable for multiple (as many as needed, not only two) permissions. It suggests adding single-responsibility PermissionsHelper class:
import android.app.Activity;
import android.app.AlertDialog;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.util.Log;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class PermissionsHelper {
private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 100; // any code you want.
public void checkAndRequestPermissions(Activity activity, String... permissions) {
List<String> listPermissionsNeeded = new ArrayList<>();
for (String permission : permissions) {
if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(permission);
}
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(activity, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
}
}
public void onRequestPermissionsResult(Activity activity, int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<>();
for (String permission : permissions) {
perms.put(permission, PackageManager.PERMISSION_GRANTED);
}
if (grantResults.length > 0) {
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
boolean allPermissionsGranted = true;
for (String permission1 : permissions) {
allPermissionsGranted = allPermissionsGranted && (perms.get(permission1) == PackageManager.PERMISSION_GRANTED);
}
if (allPermissionsGranted) {
Log.d(PermissionsHelper.class.getSimpleName(), "onRequestPermissionsResult: all permissions granted");
} else {
for (String permission2 : perms.keySet())
if (perms.get(permission2) == PackageManager.PERMISSION_GRANTED)
perms.remove(permission2);
StringBuilder message = new StringBuilder("The app has not been granted permissions:\n\n");
for (String permission : perms.keySet()) {
message.append(permission);
message.append("\n");
}
message.append("\nHence, it cannot function properly." +
"\nPlease consider granting it this permission in phone Settings.");
AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle(R.string.permission_required)
.setMessage(message)
.setPositiveButton(android.R.string.ok, (dialog, id) -> dialog.cancel());
AlertDialog alert = builder.create();
alert.show();
}
}
}
}
}
}
If one or several required permissions have not been granted by user, the detailed AlertDialog message will be shown to him.
Example of usage in Activity:
private PermissionsHelper permissionsHelper;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
checkPermissions();
//any other code
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}
private void checkPermissions() {
permissionsHelper = new PermissionsHelper();
permissionsHelper.checkAndRequestPermissions(this,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION);
}
Hope that this will be useful for someone.
Try this:
add in html following
<input type="text" id="datepicker"/>
Add in js file
$(function() {
$( "#datepicker" ).datepicker({dateFormat: 'yy', changeYear: true, changeMonth: false});
});
Add in css
.ui-datepicker-calendar {
display: none;
}
.ui-datepicker-month {
display: none;
}
.ui-datepicker-prev{
display: none;
}
.ui-datepicker-next{
display: none;
}
I created a working CodePen example demonstrating how to do this the correct way in AngularJS. The Angular $window service should be used to access any global objects since directly accessing window
makes testing more difficult.
HTML:
<section ng-app="myapp" ng-controller="MainCtrl">
Value of global variable read by AngularJS: {{variable1}}
</section>
JavaScript:
// global variable outside angular
var variable1 = true;
var app = angular.module('myapp', []);
app.controller('MainCtrl', ['$scope', '$window', function($scope, $window) {
$scope.variable1 = $window.variable1;
}]);
To bring more prominence to the useful comment by @johanvdw:
If you want to ensure your your javac file path is always know when cygwin starts, you may edit your .bash_profile
file. In this example you would add export PATH=$PATH:"/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/"
somewhere in the file.
When Cygwin starts, it'll search directories in PATH and this one for executable files to run.
This is a way to determine it for all css properties including visibility:
html:
<div id="element">div content</div>
css:
#element
{
visibility:hidden;
}
javascript:
var element = document.getElementById('element');
if(element.style.visibility == 'hidden'){
alert('hidden');
}
else
{
alert('visible');
}
It works for any css property and is very versatile and reliable.
Summary
Note, I'm presuming PyMongo, change to suit your language of choice.
Instructions:
Create the collection with an index with unique=true so you don't get duplicate records.
Iterate over your input records, creating batches of them of 15,000 records or so. For each record in the batch, create a dict consisting of the data you want to insert, presuming each one is going to be a new record. Add the 'created' and 'updated' timestamps to these. Issue this as a batch insert command with the 'ContinueOnError' flag=true, so the insert of everything else happens even if there's a duplicate key in there (which it sounds like there will be). THIS WILL HAPPEN VERY FAST. Bulk inserts rock, I've gotten 15k/second performance levels. Further notes on ContinueOnError, see http://docs.mongodb.org/manual/core/write-operations/
Record inserts happen VERY fast, so you'll be done with those inserts in no time. Now, it's time to update the relevant records. Do this with a batch retrieval, much faster than one at a time.
Iterate over all your input records again, creating batches of 15K or so. Extract out the keys (best if there's one key, but can't be helped if there isn't). Retrieve this bunch of records from Mongo with a db.collectionNameBlah.find({ field : { $in : [ 1, 2,3 ...}) query. For each of these records, determine if there's an update, and if so, issue the update, including updating the 'updated' timestamp.
Unfortunately, we should note, MongoDB 2.4 and below do NOT include a bulk update operation. They're working on that.
Key Optimization Points:
Assuming that the action button uses the same controller $scope
as the directive, just define function updateMap
on $scope
inside the link function. Your controller can then call that function when the action button is clicked.
<div ng-controller="MyCtrl">
<map></map>
<button ng-click="updateMap()">call updateMap()</button>
</div>
app.directive('map', function() {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
link: function($scope, element, attrs) {
$scope.updateMap = function() {
alert('inside updateMap()');
}
}
}
});
As per @FlorianF's comment, if the directive uses an isolated scope, things are more complicated. Here's one way to make it work: add a set-fn
attribute to the map
directive which will register the directive function with the controller:
<map set-fn="setDirectiveFn(theDirFn)"></map>
<button ng-click="directiveFn()">call directive function</button>
scope: { setFn: '&' },
link: function(scope, element, attrs) {
scope.updateMap = function() {
alert('inside updateMap()');
}
scope.setFn({theDirFn: scope.updateMap});
}
function MyCtrl($scope) {
$scope.setDirectiveFn = function(directiveFn) {
$scope.directiveFn = directiveFn;
};
}
Problem solved!
Sometime we have the column name is below format in SQLServer or MySQL table
Ex : Account Number,customer number
But Hive tables do not support column name containing spaces, so please use below solution to rename your old column names.
Solution:
val renamedColumns = df.columns.map(c => df(c).as(c.replaceAll(" ", "_").toLowerCase()))
df = df.select(renamedColumns: _*)

In some languages like JAVA you define an array using curly braces as following but in python it has a different meaning:
Java:
int[] myIntArray = {1,2,3};
String[] myStringArray = {"a","b","c"};
However, in Python, curly braces are used to define dictionaries, which needs a key:value
assignment as {'a':1, 'b':2}
To actually define an array (which is actually called list in python) you can do:
Python:
mylist = [1,2,3]
or other examples like:
mylist = list()
mylist.append(1)
mylist.append(2)
mylist.append(3)
print(mylist)
>>> [1,2,3]
It can be done in a safer way.
If your PHP array contains special characters, you need to use rawurlencode() in PHP and then use decodeURIComponent() in JS to escape those. And parse the JSON to native js. Try this:
var data = JSON.parse(
decodeURIComponent(
"<?=rawurlencode(json_encode($data));?>"
)
);
console.log(data);
How to run a shell script from a Perl program
1. Using system
system($command, @arguments);
For example:
system("sh", "script.sh", "--help" ); system("sh script.sh --help");
System will execute the $command with @arguments and return to your script when finished. You may check $! for certain errors passed to the OS by the external application. Read the documentation for system for the nuances of how various invocations are slightly different.
2. Using
exec
This is very similar to the use of system, but it will terminate your script upon execution. Again, read the documentation for exec for more.
3. Using backticks or
qx//
my $output = `script.sh --option`; my $output = qx/script.sh --option/;
The backtick operator and it's equivalent
qx//
, excute the command and options inside the operator and return that commands output to STDOUT when it finishes.There are also ways to run external applications through creative use of open, but this is advanced use; read the documentation for more.
"I don't want to use a trigger or any other thing other than Hibernate itself to generate the value for my property"
In that case, how about creating an implementation of UserType which generates the required value, and configuring the metadata to use that UserType for persistence of the mySequenceVal property?
function limitText($string,$limit){
if(strlen($string) > $limit){
$string = substr($string, 0,$limit) . "...";
}
return $string;
}
this will return 20 words. I hope it will help
$('input[type=checkbox]').change(function () {
alert('changed');
});
If you don't want to use a DateTime or TimeSpan, and just want to store the time of day, you could just store the seconds since midnight in an Int32, or (if you don't even want seconds) the minutes since midnight would fit into an Int16. It would be trivial to write the few methods required to access the Hour, Minute and Second from such a value.
The only reason I can think of to avoid DateTime/TimeSpan would be if the size of the structure is critical.
(Of course, if you use a simple scheme like the above wrapped in a class, then it would also be trivial to replace the storage with a TimeSpan in future if you suddenly realise that would give you an advantage)
you can swipe the key and the value. For example
String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
int[] v = {341, 273, 278, 329, 445};
TreeMap<Integer,String>a=new TreeMap();
for (int i = 0; i < k.length; i++)
a.put(v[i],k[i]);
System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
a.remove(a.firstEntry().getKey());
System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
How are you generating your data?
See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.
In [31]: data
Out[31]:
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)
look ?
Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float)
.
You can also call frame.astype(float)
As already mentioned, you can use the backticks or $(cat filename)
.
What was not mentioned, and I think is important to note, is that you must remember that the shell will break apart the contents of that file according to whitespace, giving each "word" it finds to your command as an argument. And while you may be able to enclose a command-line argument in quotes so that it can contain whitespace, escape sequences, etc., reading from the file will not do the same thing. For example, if your file contains:
a "b c" d
the arguments you will get are:
a
"b
c"
d
If you want to pull each line as an argument, use the while/read/do construct:
while read i ; do command_name $i ; done < filename
Run the following from the parent directory, plugins
in this case:
find . -type d -depth 1 -exec git --git-dir={}/.git --work-tree=$PWD/{} pull origin master \;
To clarify:
find .
searches the current directory-type d
to find directories, not files-depth 1
for a maximum depth of one sub-directory-exec {} \;
runs a custom command for every findgit --git-dir={}/.git --work-tree=$PWD/{} pull
git pulls the individual directoriesTo play around with find, I recommend using echo
after -exec
to preview, e.g.:
find . -type d -depth 1 -exec echo git --git-dir={}/.git --work-tree=$PWD/{} status \;
Note: if the -depth 1
option is not available, try -mindepth 1 -maxdepth 1
.
Building off of levik's answer to get the IDs of the duplicate rows you can do a GROUP_CONCAT
if your server supports it (this will return a comma separated list of ids).
SELECT GROUP_CONCAT(id), name, COUNT(*) c FROM documents GROUP BY name HAVING c > 1;
If you decide to use Underscore.js you better do
_.values(ahash)[0]
to get value, or
_.keys(ahash)[0]
to get key.
Use this:
function get_millis(){
list($usec, $sec) = explode(' ', microtime());
return (int) ((int) $sec * 1000 + ((float) $usec * 1000));
}
Bye
Had the same problem. For me it worked to call
viewPage.setAdapter( adapter );
again which caused reinstantiating the pages again.
bundle exec rake db:rollback
rails destroy model <model_name>
When you generate a model, it creates a database migration. If you run 'destroy' on that model, it will delete the migration file, but not the database table. So before run
bundle exec rake db:rollback
If we need only one column to be numeric
yyz$b <- as.numeric(as.character(yyz$b))
But, if all the columns needs to changed to numeric
, use lapply
to loop over the columns and convert to numeric
by first converting it to character
class as the columns were factor
.
yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))
Both the columns in the OP's post are factor
because of the string "n/a"
. This could be easily avoided while reading the file using na.strings = "n/a"
in the read.table/read.csv
or if we are using data.frame
, we can have character
columns with stringsAsFactors=FALSE
(the default is stringsAsFactors=TRUE
)
Regarding the usage of apply
, it converts the dataset to matrix
and matrix
can hold only a single class. To check the class
, we need
lapply(yyz, class)
Or
sapply(yyz, class)
Or check
str(yyz)
DATE: It is used for values with a date part but no time part. MySQL retrieves and displays DATE values in YYYY-MM-DD format. The supported range is 1000-01-01
to 9999-12-31
.
DATETIME: It is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in YYYY-MM-DD HH:MM:SS format. The supported range is 1000-01-01 00:00:00
to 9999-12-31 23:59:59
.
TIMESTAMP: It is also used for values that contain both date and time parts, and includes the time zone. TIMESTAMP has a range of 1970-01-01 00:00:01
UTC to 2038-01-19 03:14:07
UTC.
TIME: Its values are in HH:MM:SS format (or HHH:MM:SS format for large hours values). TIME values may range from -838:59:59
to 838:59:59
. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).
This solution will take a character vector of package names and attempt to load them, or install them if loading fails. It relies on the return behaviour of require
to do this because...
require
returns (invisibly) a logical indicating whether the required package is available
Therefore we can simply see if we were able to load the required package and if not, install it with dependencies. So given a character vector of packages you wish to load...
foo <- function(x){
for( i in x ){
# require returns TRUE invisibly if it was able to load package
if( ! require( i , character.only = TRUE ) ){
# If package was not able to be loaded then re-install
install.packages( i , dependencies = TRUE )
# Load package after installing
require( i , character.only = TRUE )
}
}
}
# Then try/install packages...
foo( c("ggplot2" , "reshape2" , "data.table" ) )

*Find the string **DTS:DataType="129"** replace with **DTS:DataType="130"**
*Save the .DTSX file.
*Open the project again on Visual Studio BIDS

Another layer of indirection:
for i in $(eval echo {1..$END}); do

If you are on linux and have inotify-tools installed, you can do this:
file=/tmp/list.txt
while [ ! -f "$file" ]
do
inotifywait -qqt 2 -e create -e moved_to "$(dirname $file)"
done
This reduces the delay introduced by sleep while still polling every "x" seconds. You can add more events if you anticipate that they are needed.
HTML:
<form id="myform">
<input id="email" oninvalid="InvalidMsg(this);" name="email" oninput="InvalidMsg(this);" type="email" required="required" />
<input type="submit" />
</form>
JAVASCRIPT :
function InvalidMsg(textbox) {
if (textbox.value == '') {
textbox.setCustomValidity('Required email address');
}
else if (textbox.validity.typeMismatch){{

Demo :
From the man git-stash
page:
The modifications stashed away by this command can be listed with git stash list, inspected with git stash show
show [<stash>]
Show the changes recorded in the stash as a diff between the stashed state and
its original parent. When no <stash> is given, shows the latest one. By default,
the command shows the diffstat, but it will accept any format known to git diff
(e.g., git stash show -p stash@{1} to view the second most recent stash in patch
form).
To list the stashed modifications
git stash list
To show files changed in the last stash
git stash show
So, to view the content of the most recent stash, run
git stash show -p
To view the content of an arbitrary stash, run something like
git stash show -p stash@{1}
What you are trying to achieve is equivalent to
interface Event {
name: string;
dateCreated: string;
type: string;
}
interface UserEvent extends Event {
UserId: string;
}
The way you defined the types does not allow for specifying inheritance, however you can achieve something similar using intersection types, as artem pointed out.
Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.
Use the subplots_adjust()
function to move the bottom of the subplot up:
fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.
Then play with the offset in the legend bbox_to_anchor
part of the legend command, to get the legend box where you want it. Some combination of setting the figsize
and using the subplots_adjust(bottom=...)
should produce a quality plot for you.
Alternative: I simply changed the line:
fig = plt.figure(1)
to:
fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')
and changed
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))
to
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))
and it shows up fine on my screen (a 24-inch CRT monitor).
Here figsize=(M,N)
sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport
option when including graphics.
Java IO using stream oriented APIs is performed using a buffer as temporary storage of data within user space. Data read from disk by DMA is first copied to buffers in kernel space, which is then transfer to buffer in user space. Hence there is overhead. Avoiding it can achieve considerable gain in performance.
We could skip this temporary buffer in user space, if there was a way directly to access the buffer in kernel space. Java NIO provides a way to do so.
ByteBuffer
is among several buffers provided by Java NIO. Its just a container or holding tank to read data from or write data to. Above behavior is achieved by allocating a direct buffer using allocateDirect()
API on Buffer.
Hi You have separate T Format and then convert as you like
// create dateFormatter with UTC time format
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.timeZone = NSTimeZone(name: "UTC")
let date = dateFormatter.dateFromString("2015-04-01T11:42:00")
// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "EEE, MMM d, yyyy - h:mm a"
dateFormatter.timeZone = NSTimeZone.localTimeZone()
let timeStamp = dateFormatter.stringFromDate(date!)
I think Piko means in his response that there is the hbm file. I have a file called Tax.java. The mapping information are saved in the hbm (=hibernate mapping) file. In the class tag there is a property called lazy. Set that property to true. The following hbm example shows a way to set the lazy property to false.
` id ...'
If you are using Annotations instead look in the hibernate documenation. http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/
I hope that helped.
Yes, ensure
ensures that the code is always evaluated. That's why it's called ensure
. So, it is equivalent to Java's and C#'s finally
.
The general flow of begin
/rescue
/else
/ensure
/end
looks like this:
begin
# something which might raise an exception
rescue SomeExceptionClass => some_variable
# code that deals with some exception
rescue SomeOtherException => some_other_variable
# code that deals with some other exception
else
# code that runs only if *no* exception was raised
ensure
# ensure that this code always runs, no matter what
# does not change the final value of the block
end
You can leave out rescue
, ensure
or else
. You can also leave out the variables in which case you won't be able to inspect the exception in your exception handling code. (Well, you can always use the global exception variable to access the last exception that was raised, but that's a little bit hacky.) And you can leave out the exception class, in which case all exceptions that inherit from StandardError
will be caught. (Please note that this does not mean that all exceptions are caught, because there are exceptions which are instances of Exception
but not StandardError
. Mostly very severe exceptions that compromise the integrity of the program such as SystemStackError
, NoMemoryError
, SecurityError
, NotImplementedError
, LoadError
, SyntaxError
, ScriptError
, Interrupt
, SignalException
or SystemExit
.)
Some blocks form implicit exception blocks. For example, method definitions are implicitly also exception blocks, so instead of writing
def foo
begin
# ...
rescue
# ...
end
end
you write just
def foo
# ...
rescue
# ...
end
or
def foo
# ...
ensure
# ...
end
The same applies to class
definitions and module
definitions.
However, in the specific case you are asking about, there is actually a much better idiom. In general, when you work with some resource which you need to clean up at the end, you do that by passing a block to a method which does all the cleanup for you. It's similar to a using
block in C#, except that Ruby is actually powerful enough that you don't have to wait for the high priests of Microsoft to come down from the mountain and graciously change their compiler for you. In Ruby, you can just implement it yourself:
# This is what you want to do:
File.open('myFile.txt', 'w') do |file|
file.puts content
end
# And this is how you might implement it:
def File.open(filename, mode='r', perm=nil, opt=nil)
yield filehandle = new(filename, mode, perm, opt)
ensure
filehandle&.close
end
And what do you know: this is already available in the core library as File.open
. But it is a general pattern that you can use in your own code as well, for implementing any kind of resource cleanup (à la using
in C#) or transactions or whatever else you might think of.
The only case where this doesn't work, if acquiring and releasing the resource are distributed over different parts of the program. But if it is localized, as in your example, then you can easily use these resource blocks.
BTW: in modern C#, using
is actually superfluous, because you can implement Ruby-style resource blocks yourself:
class File
{
static T open<T>(string filename, string mode, Func<File, T> block)
{
var handle = new File(filename, mode);
try
{
return block(handle);
}
finally
{
handle.Dispose();
}
}
}
// Usage:
File.open("myFile.txt", "w", (file) =>
{
file.WriteLine(contents);
});
DotNetZip is your friend here.
As easy as:
using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
ZipEntry e = zip["MyReport.doc"];
e.Extract(OutputStream);
}
(you can also extract to a file or other destinations).
Reading the zip file's table of contents is as easy as:
using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
foreach (ZipEntry e in zip)
{
if (header)
{
System.Console.WriteLine("Zipfile: {0}", zip.Name);
if ((zip.Comment != null) && (zip.Comment != ""))
System.Console.WriteLine("Comment: {0}", zip.Comment);
System.Console.WriteLine("\n{1,-22} {2,8} {3,5} {4,8} {5,3} {0}",
"Filename", "Modified", "Size", "Ratio", "Packed", "pw?");
System.Console.WriteLine(new System.String('-', 72));
header = false;
}
System.Console.WriteLine("{1,-22} {2,8} {3,5:F0}% {4,8} {5,3} {0}",
e.FileName,
e.LastModified.ToString("yyyy-MM-dd HH:mm:ss"),
e.UncompressedSize,
e.CompressionRatio,
e.CompressedSize,
(e.UsesEncryption) ? "Y" : "N");
}
}
Edited To Note: DotNetZip used to live at Codeplex. Codeplex has been shut down. The old archive is still available at Codeplex. It looks like the code has migrated to Github:
This should do it:
//Returns the index of the first occurence of char c in char* string. If not found -1 is returned.
int get_index(char* string, char c) {
char *e = strchr(string, c);
if (e == NULL) {
return -1;
}
return (int)(e - string);

Java makes regex too complicated and it does not follow the perl-style. Take a look at MentaRegex to see how you can accomplish that in a single line of Java code:
String[] matches = match("aa11bb22", "/(\\d+)/g" ); // => ["11", "22"]
ls -sh video.mp4 | sed s/video.mp4//g
output, 5.6M
The +
allow 'select' only first not nested element , the >
select nested elements only - the better is to use ~
which allow to select arbitrary element which is child of parent hovered element. Using opacity/width and transition you can provide smooth appear

FileReader
uses Java's platform default encoding, which depends on the system settings of the computer it's running on and is generally the most popular encoding among users in that locale.
If this "best guess" is not correct then you have to specify the encoding explicitly. Unfortunately, FileReader
does not allow this (major oversight in the API). Instead, you have to use new InputStreamReader(new FileInputStream(filePath), encoding)
and ideally get the encoding from metadata about the file.
I use this subtle alias:
alias vim='gnome-terminal -- vim'
-x is deprecated now. We need to use -- instead
are you running the example from the node_modules folder?
They are not supposed to be ran from there.
Create the following file on your project instead:
post-data.js
var Curl = require( 'node-libcurl' ).Curl,
querystring = require( 'querystring' );
var curl = new Curl(),
url = 'http://posttestserver.com/post.php',
data = { //Data to send, inputName : value
'input-arr[0]' : 'input-arr-val0',
'input-arr[1]' : 'input-arr-val1',
'input-arr[2]' : 'input-arr-val2',
'input-name' : 'input-val'
};
//You need to build the query string,
// node has this helper function, but it's limited for real use cases (no support for
array values for example)
data = querystring.stringify( data );
curl.setOpt( Curl.option.URL, url );
curl.setOpt( Curl.option.POSTFIELDS, data );
curl.setOpt( Curl.option.HTTPHEADER, ['User-Agent: node-libcurl/1.0'] );
curl.setOpt( Curl.option.VERBOSE, true );
console.log( querystring.stringify( data ) );
curl.perform();
curl.on( 'end', function( statusCode, body ) {
console.log( body );
this.close();
});
curl.on( 'error', curl.close.bind( curl ) );
Run with node post-data.js
Are we talking about standard java.io.FileReader
? Won't work, but it's not hard without it.
/src/main/resources
maven directory contents are placed in the root of your CLASSPATH, so you can simply retrieve it using:
InputStream is = getClass().getResourceAsStream("/storedProcedures.sql");
If the result is not null
(resource not found), feel free to wrap it in a reader:
Reader reader = new InputStreamReader(is);
This code is a very good example for a dynamic column with a cursor, since you cannot use '+' in @STATEMENT:

DECLARE @inputList NVARCHAR(4000) = ''
DECLARE @field sysname = '' --COLUMN NAME
DECLARE @my_cur CURSOR
EXECUTE SP_EXECUTESQL
N'SET @my_cur = CURSOR FAST_FORWARD FOR
SELECT
CASE @field
WHEN ''fn'' then fn
WHEN ''n_family_name'' then n_family_name
END
FROM
dbo.vCard
WHERE
CASE @field
WHEN ''fn'' then fn
WHEN ''n_family_name'' then n_family_name
END
LIKE ''%''+@query+''%'';
OPEN @my_cur;',
N'@field sysname, @query NVARCHAR(4000), @my_cur CURSOR OUTPUT',
@field = @field,
@query = @query,
@my_cur = @my_cur OUTPUT
FETCH NEXT FROM @my_cur INTO @inputList
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @inputList
FETCH NEXT FROM @my_cur INTO @inputList
END
RETURN
We can use a separate function for performing a continue statement work. suppose you have following problem:
for i=1 to 10
if(condition) then 'for loop body'
contionue
End If
Next
Here we will use a function call for for loop body:
for i=1 to 10
Call loopbody()
next
function loopbody()
if(condition) then 'for loop body'
Exit Function
End If
End Function
loop will continue for function exit statement....

Divide and Conquer
Divide and Conquer works by dividing the problem into sub-problems, conquer each sub-problem recursively and combine these solutions.
Dynamic Programming
Dynamic Programming is a technique for solving problems with overlapping subproblems. Each sub-problem is solved only once and the result of each sub-problem is stored in a table ( generally implemented as an array or a hash table) for future references. These sub-solutions may be used to obtain the original solution and the technique of storing the sub-problem solutions is known as memoization.
You may think of DP = recursion + re-use
A classic example to understand the difference would be to see both these approaches towards obtaining the nth fibonacci number. Check this material from MIT.

There is a simple example of convert enumeration to list. for this i used Collections.list(enum)
method.
public class EnumerationToList {
public static void main(String[] args) {
Vector<String> vt = new Vector<String>();
vt.add("java");
vt.add("php");
vt.add("array");
vt.add("string");
vt.add("c");
Enumeration<String> enm = vt.elements();
List<String> ll = Collections.list(enm);
System.out.println("List elements: " + ll);
}
}

You can use multiple font faces quite easily. Below is an example of how I used it in the past:
<!--[if (IE)]><!-->
<style type="text/css" media="screen">
@font-face {
font-family: "Century Schoolbook";
src: url(/fonts/century-schoolbook.eot);
}
@font-face {
font-family: "Chalkduster";
src: url(/fonts/chalkduster.eot);
}
</style>
<!--<![endif]-->
<!--[if !(IE)]><!-->
<style type="text/css" media="screen">
@font-face {
font-family: "Century Schoolbook";
src: url(/fonts/century-schoolbook.ttf);
}
@font-face {
font-family: "Chalkduster";
src: url(/fonts/chalkduster.ttf);
}
</style>
<!--<![endif]-->
It is worth noting that fonts can be funny across different Browsers. Font face on earlier browsers works, but you need to use eot files instead of ttf.
That is why I include my fonts in the head of the html file as I can then use conditional IE tags to use eot or ttf files accordingly.
If you need to convert ttf to eot for this purpose there is a brilliant website you can do this for free online, which can be found at http://ttf2eot.sebastiankippe.com/.
Hope that helps.

The whereColumn
method can be passed an array of multiple conditions. These conditions will be joined using the and
operator.
Example:
$users = DB::table('users')
->whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at']
])->get();
$users = User::whereColumn([

It looks like you are trying to start the Python interpreter by running the command python
.
However the interpreter is already started. It is interpreting python
as a name of a variable, and that name is not defined.
Try this instead and you should hopefully see that your Python installation is working as expected:
print("Hello world!")
The snippet you're showing doesn't seem to be directly responsible for the error.
This is how you can CAUSE the error:
namespace MyNameSpace
{
int i; <-- THIS NEEDS TO BE INSIDE THE CLASS
class MyClass
{
...
}
}
If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }
.
Since Python is interpreted and run in C, it is possible to set colors without a module.
You can define a class for colors like this:
class color:
PURPLE = '\033[1;35;48m'
CYAN = '\033[1;36;48m'
BOLD = '\033[1;37;48m'
BLUE = '\033[1;34;48m'
GREEN = '\033[1;32;48m'
YELLOW = '\033[1;33;48m'
RED = '\033[1;31;48m'
BLACK = '\033[1;30;48m'
UNDERLINE = '\033[4;37;48m'
END = '\033[1;37;0m'
When writing code, you can simply write:
print(color.BLUE + "hello friends" + color.END)
Note that the color you choose will have to be capitalized like your class definition, and that these are color choices that I personally find satisfying. For a fuller array of color choices and, indeed, background choices as well, please see: https://gist.github.com/RabaDabaDoba/145049536f815903c79944599c6f952a.
This is code for C, but can easily be adapted to Python once you realize how the code is written.
Take BLUE for example, since that is what you are wanting to display.
BLUE = '033[1;37;48m'
\033 tells Python to break and pay attention to the following formatting.
1 informs the code to be bold. (I prefer 1 to 0 because it pops more.)
34 is the actual color code. It chooses blue.
48m is the background color. 48m is the same shade as the console window, so it seems there is no background.
I agree that the way to do is to redirect to the new controller in usual cases.
I came across a use case where I needed to display the same page to 2 different kind of users (backend user previewing the page of a frontend user) so in my opinion what I needed was genuinely to call the frontend controller from the backend controller.
I solved the problem by making the frontend method static and wrapping it in another method. Hope it helps!
//==========
// Frontend
//==========
function profile()
{
//Access check
//Get profile id
$id = get_user_id();
return self::_profile($id);
}
static function _profile($id)
{
$CI = &get_instance();
//Prepare page
//Load view
}
//==========
// Backend
//==========
function preview_profile($id)
{
$this->load->file('controllers/frontend.php', false);
Frontend::_profile($id);
}
Necromancing.
YES YOU CAN, and this is how.
A secret tip for those migrating large junks chunks of code:
The following method is an evil carbuncle of a hack which is actively engaged in carrying out the express work of satan (in the eyes of .NET Core framework developers), but it works:
In public class Startup
add a property
public IConfigurationRoot Configuration { get; }
And then add a singleton IHttpContextAccessor to DI in ConfigureServices.
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<Microsoft.AspNetCore.Http.IHttpContextAccessor, Microsoft.AspNetCore.Http.HttpContextAccessor>();
Then in Configure
public void Configure(
IApplicationBuilder app
,IHostingEnvironment env
,ILoggerFactory loggerFactory
)
{
add the DI Parameter IServiceProvider svp
, so the method looks like:
public void Configure(
IApplicationBuilder app
,IHostingEnvironment env
,ILoggerFactory loggerFactory
,IServiceProvider svp)
{
Next, create a replacement class for System.Web:
namespace System.Web
{
namespace Hosting
{
public static class HostingEnvironment
{
public static bool m_IsHosted;
static HostingEnvironment()
{
m_IsHosted = false;
}
public static bool IsHosted
{
get
{
return m_IsHosted;
}
}
}
}
public static class HttpContext
{
public static IServiceProvider ServiceProvider;
static HttpContext()
{ }
public static Microsoft.AspNetCore.Http.HttpContext Current
{
get
{
// var factory2 = ServiceProvider.GetService<Microsoft.AspNetCore.Http.IHttpContextAccessor>();
object factory = ServiceProvider.GetService(typeof(Microsoft.AspNetCore.Http.IHttpContextAccessor));
// Microsoft.AspNetCore.Http.HttpContextAccessor fac =(Microsoft.AspNetCore.Http.HttpContextAccessor)factory;
Microsoft.AspNetCore.Http.HttpContext context = ((Microsoft.AspNetCore.Http.HttpContextAccessor)factory).HttpContext;
// context.Response.WriteAsync("Test");
return context;
}
}
} // End Class HttpContext
}
Now in Configure, where you added the IServiceProvider svp
, save this service provider into the static variable "ServiceProvider" in the just created dummy class System.Web.HttpContext (System.Web.HttpContext.ServiceProvider)
and set HostingEnvironment.IsHosted to true
System.Web.Hosting.HostingEnvironment.m_IsHosted = true;
this is essentially what System.Web did, just that you never saw it (I guess the variable was declared as internal instead of public).
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider svp)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
ServiceProvider = svp;
System.Web.HttpContext.ServiceProvider = svp;
System.Web.Hosting.HostingEnvironment.m_IsHosted = true;
app.UseCookieAuthentication(new CookieAuthenticationOptions()
{
AuthenticationScheme = "MyCookieMiddlewareInstance",
LoginPath = new Microsoft.AspNetCore.Http.PathString("/Account/Unauthorized/"),
AccessDeniedPath = new Microsoft.AspNetCore.Http.PathString("/Account/Forbidden/"),
AutomaticAuthenticate = true,
AutomaticChallenge = true,
CookieSecure = Microsoft.AspNetCore.Http.CookieSecurePolicy.SameAsRequest
, CookieHttpOnly=false
});
Like in ASP.NET Web-Forms, you'll get a NullReference when you're trying to access a HttpContext when there is none, such as it used to be in Application_Start
in global.asax.
I stress again, this only works if you actually added
services.AddSingleton<Microsoft.AspNetCore.Http.IHttpContextAccessor, Microsoft.AspNetCore.Http.HttpContextAccessor>();
like I wrote you should.
Welcome to the ServiceLocator pattern within the DI pattern ;)
For risks and side effects, ask your resident doctor or pharmacist - or study the sources of .NET Core at github.com/aspnet, and do some testing.
Perhaps a more maintainable method would be adding this helper class
namespace System.Web
{
public static class HttpContext
{
private static Microsoft.AspNetCore.Http.IHttpContextAccessor m_httpContextAccessor;
public static void Configure(Microsoft.AspNetCore.Http.IHttpContextAccessor httpContextAccessor)
{
m_httpContextAccessor = httpContextAccessor;
}
public static Microsoft.AspNetCore.Http.HttpContext Current
{
get
{
return m_httpContextAccessor.HttpContext;
}
}
}
}
And then calling HttpContext.Configure in Startup->Configure
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider svp)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
System.Web.HttpContext.Configure(app.ApplicationServices.
GetRequiredService<Microsoft.AspNetCore.Http.IHttpContextAccessor>()
);
Try connecting to a vpn, if possible. That was the reason I was facing problem. Tip: if you're using an ec2 machine, try rebooting it. This worked for me the other day :)
Pickle save:
try:
import cPickle as pickle
except ImportError: # Python 3.x
import pickle
with open('data.p', 'wb') as fp:
pickle.dump(data, fp, protocol=pickle.HIGHEST_PROTOCOL)
See the pickle module documentation for additional information regarding the protocol
argument.
Pickle load:
with open('data.p', 'rb') as fp:
data = pickle.load(fp)
JSON save:
import json
with open('data.json', 'w') as fp:
json.dump(data, fp)
Supply extra arguments, like sort_keys
or indent
, to get a pretty result. The argument sort_keys will sort the keys alphabetically and indent will indent your data structure with indent=N
spaces.
json.dump(data, fp, sort_keys=True, indent=4)
JSON load:
with open('data.json', 'r') as fp:
data = json.load(fp)
I strongly advocate for PostGis. It's specific for that kind of datatype and it has out of the box methods to calculate distance between points, among other GIS operations that you can find useful in the future
Use this to limit the depth to 2:
Get-ChildItem \*\*\*,\*\*,\*
The way it works is that it returns the children at each depth 2,1 and 0.
Explanation:
This command
Get-ChildItem \*\*\*
returns all items with a depth of two subfolders. Adding \* adds an additional subfolder to search in.
In line with the OP question, to limit a recursive search using get-childitem you are required to specify all the depths that can be searched.

I faced this issue a lot when using position: absolute;
, I faced this issue by using position: relative
in the child element. don't need to change position: absolute
to relative
, just need to add in the child element look into the beneath two examples:
let toggle = document.getElementById('toggle')
toggle.addEventListener("click", () => {
toggle.classList.toggle('change');

I was using a .Net Core 2.1 API with the [FromBody]
attribute and I had to use the following solution to successfully Post to it:
_apiClient = new HttpClient();
_apiClient.BaseAddress = new Uri(<YOUR API>);
var MyObject myObject = new MyObject(){
FirstName = "Me",
LastName = "Myself"
};
var stringified = JsonConvert.SerializeObject(myObject);
var result = await _apiClient.PostAsync("api/appusers", new StringContent(stringified, Encoding.UTF8, "application/json"));
As Tr?n Si Long suggested, use
String[] mStrings = new String[title.length];
And replace string concatation with proper parenthesis.
mStrings[i] = (urlbase + (title[i].replaceAll("[^a-zA-Z]", ""))).toLowerCase() + imgSel;
Try this. If it's problem due to concatation, it will be resolved with proper brackets. Hope it helps.
The answer above is probably the correct way to do it, but didn't work for me.
The hacky way that solved it for me was the following:
ax = <whatever your plot is>
# get the current labels
labels = [item.get_text() for item in ax.get_xticklabels()]
# Beat them into submission and set them back again
ax.set_xticklabels([str(round(float(label), 2)) for label in labels])
# Show the plot, and go home to family
plt.show()
Thanks to @bmjohn's answer above. Here is a working Xamarin / C# version of the that answer's code, to save others the time of transcription:
AppDelegate.cs
public UIInterfaceOrientationMask OrientationLock = UIInterfaceOrientationMask.All;
public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations(UIApplication application, UIWindow forWindow)
{
return this.OrientationLock;
}
Static OrientationUtility.cs class:
public static class OrientationUtility
{
public static void LockOrientation(UIInterfaceOrientationMask orientation)
{
var appdelegate = (AppDelegate) UIApplication.SharedApplication.Delegate;
if(appdelegate != null)
{
appdelegate.OrientationLock = orientation;
}
}
public static void LockOrientation(UIInterfaceOrientationMask orientation, UIInterfaceOrientation RotateToOrientation)
{
LockOrientation(orientation);
UIDevice.CurrentDevice.SetValueForKey(new NSNumber((int)RotateToOrientation), new NSString("orientation"));
}
}
View Controller:
public override void ViewDidAppear(bool animated)
{
base.ViewWillAppear(animated);
OrientationUtility.LockOrientation(UIInterfaceOrientationMask.Portrait, UIInterfaceOrientation.Portrait);
}
public override void ViewWillDisappear(bool animated)
{
base.ViewWillDisappear(animated);
OrientationUtility.LockOrientation(UIInterfaceOrientationMask.All);
}
You can try:
In HTML:
<asp:TextBox ID="TextBox1" runat="server" onKeyDown="submitButton(event)"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
And javascript:

$('#Button1').trigger('click');
}
}
Code behind:
protected void Button1_Click(object sender, EventArgs e)

This happens to me occasionally, usually it's just a simple oversight. Just pay attention to details, simple typos, etc. For example when copy/pasting import statements, like this:
This is how I base
ically think of the problem.
my.df <- data.frame(group = rep(c(1,2), each = 3),
score = runif(6), info = letters[1:6])
my.agg <- with(my.df, aggregate(score, list(group), max))
my.df.split <- with(my.df, split(x = my.df, f = group))
my.agg$info <- unlist(lapply(my.df.split, FUN = function(x) {
x[which(x$score == max(x$score)), "info"]
}))
> my.agg
Group.1 x info
1 1 0.9344336 a

List<Vertex<E>> neighbors;
}
}
Setting of TAGs is really useful when you have a ListView and want to recycle/reuse the views. In that way the ListView is becoming very similar to the newer RecyclerView.
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder = null;
if ( convertView == null )
{
/* There is no view at this position, we create a new one.
In this case by inflating an xml layout */
convertView = mInflater.inflate(R.layout.listview_item, null);
holder = new ViewHolder();
holder.toggleOk = (ToggleButton) convertView.findViewById( R.id.togOk );
convertView.setTag (holder);
}
else
{
/* We recycle a View that already exists */
holder = (ViewHolder) convertView.getTag ();
}
// Once we have a reference to the View we are returning, we set its values.
// Here is where you should set the ToggleButton value for this item!!!
holder.toggleOk.setChecked( mToggles.get( position ) );
return convertView;
}
WinMount provides an easiest way to mount VMDK as a virtual disk. You can read or write to the vmdk file without loading the virtual system. Here shows you how to do: http://www.winmount.com/mount_vmdk.html
I understand the problem of performing the segue at one place and maintaining the state to send parameters in prepare for segue.
I figured out a way to do this. I've added a property called userInfoDict to ViewControllers using a category. and I've override perform segue with identifier too, in such a way that If the sender is self(means the controller itself). It will pass this userInfoDict to the next ViewController.
Here instead of passing the whole UserInfoDict you can also pass the specific params, as sender and override accordingly.
1 thing you need to keep in mind. don't forget to call super method in ur performSegue method.
According to the documentation since Symfony 2.1 simply use this shortcut :
$user = $this->getUser();
The above is still working on Symfony 3.2 and is a shortcut for this :
$user = $this->get('security.token_storage')->getToken()->getUser();
The
security.token_storage
service was introduced in Symfony 2.6. Prior to Symfony 2.6, you had to use thegetToken()
method of thesecurity.context
service.
Example : And if you want directly the username :
$username = $this->getUser()->getUsername();
The user will be an object and the class of that object will depend on your user provider.
Based on your comment under @Raul's answer, I can think of two ways to include a callback:
getScript
call the file that loads the css.<style>
. Your callback would be the callback from $.get
or whatever you use to load the css file contents.The shortest and the simplest way is :
DECLARE @now AS DATETIME = GETDATE()
SELECT CONVERT(VARCHAR, @now, 23)

I have a .Net Core 3.1 MSTest project with similar issue. This post provided clues to fix it.
Breaking this down to a simple answer for .Net core 3.1:
If it is a MSTest project:
rename file in project to testhost.dll.config
OR
Use post-build command provided by DeepSpace101
In Angular 2, change detection is automatic... $scope.$watch()
and $scope.$digest()
R.I.P.
Unfortunately, the Change Detection section of the dev guide is not written yet (there is a placeholder near the bottom of the Architecture Overview page, in section "The Other Stuff").
Here's my understanding of how change detection works:
setTimeout()
inside our components rather than something like $timeout
... because setTimeout()
is monkey patched.ChangeDetectorRef
.) These change detectors are created when Angular creates components. They keep track of the state of all of your bindings, for dirty checking. These are, in a sense, similar to the automatic $watches()
that Angular 1 would set up for {{}}
template bindings.onPush
change detection strategy on any of your components), every component in the tree is examined once (TTL=1)... from the top, in depth-first order. (Well, if you're in dev mode, change detection runs twice (TTL=2). See ApplicationRef.tick() for more about this.) It performs dirty checking on all of your bindings, using those change detector objects.
ngOnChanges()
to be notified of changes. ngDoCheck()
(see this SO answer for more on this). Other references to learn more:
onPush
.In addition to @JBNizet's answer, my general use case for ifPresent
is to combine .isPresent()
and .get()
:
Old way:
Optional opt = getIntOptional();
if(opt.isPresent()) {
Integer value = opt.get();
// do something with value
}
New way:
Optional opt = getIntOptional();
opt.ifPresent(value -> {
// do something with value
})
This, to me, is more intuitive.
You can use "break", already mentioned in the answers above. If you need to return some values. You can use "return" like the code below:
while(true){
if(some condition){
do something;
return;}
else{
do something;
return;}
}
in this case, this while is in under a method which is returning some kind of values.

For Mountain Lion, Apple's java is up to 1.6.0_35-b10-428.jdk as of today.
It is indeed located under /Library/Java/JavaVirtualMachines .
You just download
"Java for OS X 2012-005 Developer Package" (Sept 6, 2012)
from
http://connect.apple.com/
In my view, Apple's naming is at least a bit confusing; why "-005" - is this the fifth version, or the fifth of five installers one needs?
And then run the installer; then follow the above steps inside Eclipse.
Use this:
mysqli_query($this->db_link, $query) or die(mysqli_error($this->db_link));
# mysqli_query($link,$query) returns 0 if there's an error.
# mysqli_error($link) returns a string with the last error message
You can also use this to print the error code.
echo mysqli_errno($this->db_link);
Change the user to postgres :
su - postgres
Create User for Postgres
$ createuser testuser
Create Database
$ createdb testdb
Acces the postgres Shell
psql ( enter the password for postgressql)
Provide the privileges to the postgres user
$ alter user testuser with encrypted password 'qwerty';
$ grant all privileges on database testdb to testuser;
To make it simpler to follow, I will summarize the above answers:
Let`s say the table is called Customer it has 4 columns/less or more...
you want to add a new column to the table where every time when there is insert... then that column keeps a record of the time the event happened.
Solution:
add a new column, let`s say timepurchase is the new column, to the table with data type datetime.
Then run the following alter:
ALTER TABLE Customer ADD CONSTRAINT DF_Customer DEFAULT GETDATE() FOR timePurchase
I had to use a similar solution for Portuguese (Brazil):
<?php
$scheduled_day = '2018-07-28';
$days = ['Dom','Seg','Ter','Qua','Qui','Sex','Sáb'];
$day = date('w',strtotime($scheduled_day));
$scheduled_day = date('d-m-Y', strtotime($scheduled_day))." ($days[$day])";
// provides 28-07-2018 (Sáb)
As an addendum, if you want to reapply your changes on top of the remote, you can also try:
git pull --rebase origin master
If you then want to undo some of your changes (but perhaps not all of them) you can use:
git reset SHA_HASH
Then do some adjustment and recommit.
You also need to set the option CURLOPT_COOKIEFILE
.
The manual describes this as
The name of the file containing the cookie data. The cookie file can be in Netscape format, or just plain HTTP-style headers dumped into a file. If the name is an empty string, no cookies are loaded, but cookie handling is still enabled.
Since you are using the cookie jar you end up saving the cookies when the requests finish, but since the CURLOPT_COOKIEFILE
is not given, cURL isn't sending any of the saved cookies on subsequent requests.
\d
is called a character class and will match digits. It is equal to [0-9]
.
+
matches 1 or more occurrences of the character before.
So \d+
means match 1 or more digits.
Fatal error: Out of memory (allocated SOLVED
i had similar problem, for months no solution. finally i was checking in one of the apache folders i.e(\apache\conf\extra) i came across this file that controls the memory allocation of apache. the file name is httpd-mpm in that file you are to increase the MaxMemFree which is set 2048 to something higher, i took mine to 10000 for the first MaxMemFree (IfModule !mpm_netware_module) then made the second one MaxMemFree to 5000 IfModule mpm_netware_module.
These solved my problem. hope it helps
you can also use a namedQuery named findAll for all your entities and call it in your generic FindAll with
entityManager.createNamedQuery(persistentClass.getSimpleName()+"findAll").getResultList();
function Uint8ToBase64(u8Arr){
var CHUNK_SIZE = 0x8000; //arbitrary number
var index = 0;
var length = u8Arr.length;
var result = '';
var slice;
while (index < length) {
slice = u8Arr.subarray(index, Math.min(index + CHUNK_SIZE, length));
result += String.fromCharCode.apply(null, slice);
index += CHUNK_SIZE;
}
return btoa(result);
}
You can use this function if you have a very large Uint8Array. This is for Javascript, can be useful in case of FileReader readAsArrayBuffer.
Run it through a fairly simple regex: [^a-zA-Z]
And then check it's length separately:
if(string.Length > 7)
The error is pretty clear: "cannot find symbol". Some dependencies can't be resolved (you even have the line and column in the trace of the reference that can't be resolved):

Below a couple of things to verify:
Maven is working fine, you have a mistake somewhere.
Moignans answer here works fine. Here is another peace of info in case it helps,
#if DEBUG
let a = 2
#else
let a = 3
#endif
You can negate the macros like below,
#if !RELEASE
let a = 2
#else
let a = 3
#endif
You can use the below code on your string and you will get the complete string without html part.
string title = "<b> Hulk Hogan's Celebrity Championship Wrestling <font color=\"#228b22\">[Proj # 206010]</font></b> (Reality Series, )".Replace(" ",string.Empty);
string s = Regex.Replace(title, "<.*?>", String.Empty);
Try this:
document.addEventListener("keydown", KeyCheck); //or however you are calling your method
function KeyCheck(event)
{
var KeyID = event.keyCode;
switch(KeyID)
{
case 8:
alert("backspace");
break;
case 46:
alert("delete");
break;
default:
break;
}
}
If you are using Angular 1.3 or above, I recommend that you use "track by" in your ng-repeat. Angular doesn't add a "$$hashKey" property to the objects in your array if you use "track by". You also get performance benefits, if something in your array changes, angular doesn't recreate the entire DOM structure for your ng-repeat, it instead recreates the part of the DOM for the values in your array that have changed.
Use a keep alive.
On login:
session_start();
$_SESSION['last_action'] = time();
An ajax call every few (eg 20) seconds:
windows.setInterval(keepAliveCall, 20000);
Server side keepalive.php:
session_start();
$_SESSION['last_action'] = time();
On every other action:
session_start();
if ($_SESSION['last_action'] < time() - 30 /* be a little tolerant here */) {
// destroy the session and quit

Your code has lots of errors.
dm$Day
and dm$day
. Probably not the same thingDate
and Visits
. So you would access them (I'm guessing) as dm$Date
and dm$Visits
%Y-%m-%d
this should be %m/%d/%Y
The following code should plot what you want:
dm$newday = as.Date(dm$Date, "%m/%d/%Y")
plot(dm$newday, dm$Visits)
Calling multiple functions on onClick for any element, you can create a wrapper function, something like this.
wrapperFunction = () => {
//do something
function 1();
//do something
function 2();
//do something
function 3();
}
These functions can be defined as a method on the parent class and then called from the wrapper function.
You may have the main element which will cause the onChange like this,
<a href='#' onClick={this.wrapperFunction}>Some Link</a>

Here is java sample code for swapping java chars recursively.. You can get full sample code at http://java2novice.com/java-interview-programs/string-reverse-recursive/
public String reverseString(String str){
if(str.length() == 1){
return str;
} else {
reverse += str.charAt(str.length()-1)
+reverseString(str.substring(0,str.length()-1));
return reverse;
}
}
The best (and only) method is to set correct HTTP headers, specifically these ones: "Expires", "Last-Modified", and "Cache-Control". How to do it depends on the server software you use.
In Improving performance… look for "Optimization on server side" for general considerations and relevant links and for "Client-side cache" for the Apache-specific advice.
If you are a fan of nginx (or nginx in plain English) like I am, you can easily configure it too:
location /images {
...
expires 4h;
}
In the example above any file from /images/ will be cached on the client for 4 hours.
Now when you know right words to look for (HTTP headers "Expires", "Last-Modified", and "Cache-Control"), just peruse the documentation of the web server you use.
If you are using Linux and you got the permission error, you will need to raise the allowed limit in the /etc/limits.conf
or /etc/security/limits.conf
file (where the file is located depends on your specific Linux distribution).
For example to allow anyone on the machine to raise their number of open files up to 10000 add the line to the limits.conf
file.
* hard nofile 10000
Then logout and relogin to your system and you should be able to do:
ulimit -n 10000
without a permission error.
In /etc/apache2/ports.conf
, change the port as
Listen 8079
Then go to /etc/apache2/sites-enabled/000-default.conf
And change the first line as
<VirtualHost *: 8079>
Now restart
sudo service apache2 restart
Apache will now listen on port 8079 and redirect to /var/www/html
If you used read.table()
(or one of it's ilk, e.g. read.csv()
) then the easy fix is to change the call to:
read.table(file = "foo.txt", row.names = 1, ....)
where ....
are the other arguments you needed/used. The row.names
argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table
for details/info.
If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames
attribute and remove the first variable from the object (assuming obj
is your object)
rownames(obj) <- obj[, 1] ## set rownames
obj <- obj[, -1] ## remove the first variable
Bind to the change
event instead of click
. However, you will probably still need to check whether or not the checkbox is checked:
$(".checkbox").change(function() {
if(this.checked) {
//Do stuff
}
});
The main benefit of binding to the Redacted in commentschange
event over the click
event is that not all clicks on a checkbox will cause it to change state. If you only want to capture events that cause the checkbox to change state, you want the aptly-named change
event.
Also note that I've used this.checked
instead of wrapping the element in a jQuery object and using jQuery methods, simply because it's shorter and faster to access the property of the DOM element directly.
Edit (see comments)
To get all checkboxes you have a couple of options. You can use the :checkbox
pseudo-selector:
$(":checkbox")
Or you could use an attribute equals selector:
$("input[type='checkbox']")
One very minor improvement could potentially be to save the double value that you're computing so that you only compute it on the first access. This won't be a big win unless you're accessing this number a lot, but it's not overly difficult to do, either.
One additional point might be the error checking you do in the denominator...you automatically change 0 to 1. Not sure if this is correct for your particular application, but in general if someone is trying to divide by 0, something is very wrong. I'd let this throw an exception (a specialized exception if you feel it's needed) rather than change the value in a seemingly arbitrary way that isn't known to the user.
In constrast with some other comments, about adding methods to add subtract, etc...since you didn't mention needing them, I'm assuming you don't. And unless you're building a library that is really going to be used in many places or by other people, go with YAGNI (you ain't going to need it, so it shouldn't be there.)
As Quentin and other suggested this cannot totally be done with css(partially done with content attribute of css). Instead you should use javascript/jQuery to achieve this,
JS:
document.getElementsByClassName("mandatory")[0].title = "mandatory";
or using jQuery:
$('.mandatory').attr('title','mandatory');
document.getElementsByClassName('mandatory')[0].setAttribute('title', 'mandatory');_x000D_
_x000D_
$('.jmandatory').attr('title', 'jmandatory');
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
Place the Mouse Over the following elements to see the title,_x000D_
<br/><br/>_x000D_
<b><label class="mandatory">->Javascript Mandatory</label></b>_x000D_
<br/><br/>_x000D_
<b><label class="jmandatory">->jQuery Mandatory</label></b>
_x000D_
I had this problem, too.
Possible causes in my case: I had deleted a duplicated view twice and a view model. I reverted one of the deletes and then the InitializeComponent error appeared. I took these steps.
If you are in a interactive session and don't want to restart you can remove the shadowing with
del list
In order to create an array of objects, the objects need a constructor that doesn't take any paramters (that creates a default form of the object, eg. with both strings empty). This is what the error message means. The compiler automatically generates a constructor which creates an empty object unless there are any other constructors.
If it makes sense for the array elements to be created empty (in which case the members acquire their default values, in this case, empty strings), you should:
-Write an empty constructor:
class name {
public:
string first;
string last;
name() { }
name(string a, string b){
first = a;
last = b;
}
};
-Or, if you don't need it, remove the existing constructor.
If an "empty" version of your class makes no sense, there is no good solution to provide initialisation paramters to all the elements of the array at compile time. You can:
init()
function which does the real initialisationvector
, and on initialisation create the objects and insert them into the vector
, either using vector::insert
or a loop, and trust that not doing it at compile time doesn't matter.std::vector<std::string> v = { "xyzzy", "plugh", "abracadabra" };
`
>>> a=[]
>>> a.append([1,2])
>>> a
[[1, 2]]
>>> a=[]
>>> a+=[1,2]
>>> a
[1, 2]
See that append adds a single element to the list, which may be anything. +=[]
joins the lists.
