With async you just do:
await Task.Run(() => do some stuff);
// continue doing stuff on the same context as before.
// while it is the default it is nice to be explicit about it with:
await Task.Run(() => do some stuff).ConfigureAwait(true);
However:
await Task.Run(() => do some stuff).ConfigureAwait(false);
// continue doing stuff on the same thread as the task finished on.
This issue may also occur if you have multiple versions of the same support library android-support-v4.jar
. If your project is using other library projects that contain different-2 versions of the support library. To resolve the issue keep the same version of support library at each place.
I am using: Apache Commons Lang: StringUtils.ordinalIndexOf()

Theres a few ways you can do this. You can either add a background to the canvas you are currently working on, which if the canvas isn't going to be redrawn every loop is fine. Otherwise you can make a second canvas underneath your main canvas and draw the background to it. The final way is to just use a standard <img>
element placed under the canvas. To draw a background onto the canvas element you can do something like the following:
var canvas = document.getElementById("canvas"),
ctx = canvas.getContext("2d");
canvas.width = 903;
canvas.height = 657;
var background = new Image();
background.src = "http://www.samskirrow.com/background.png";
// Make sure the image is loaded first otherwise nothing will draw.
background.onload = function(){
ctx.drawImage(background,0,0);
}
// Draw whatever else over top of it on the canvas.
You're using the wrong post parameters:
var dataString = 'name='+ name + '&email=' + email + '&text=' + text;
^^^^-$_POST['name']
^^^^--$_POST['name']
etc....
The javascript/html IDs are irrelevant to the actual POST, especially when you're building your own data string and don't use those same IDs.
From your question, it is unclear as-to which columns you want to use to determine duplicates. The general idea behind the solution is to create a key based on the values of the columns that identify duplicates. Then, you can use the reduceByKey or reduce operations to eliminate duplicates.
Here is some code to get you started:
def get_key(x):
return "{0}{1}{2}".format(x[0],x[2],x[3])
m = data.map(lambda x: (get_key(x),x))
Now, you have a key-value RDD
that is keyed by columns 1,3 and 4.
The next step would be either a reduceByKey
or groupByKey
and filter
.
This would eliminate duplicates.
r = m.reduceByKey(lambda x,y: (x))
#include <stdio.h>

int main(void){
char word[17], outword[33];//17:16+1, 33:16*2+1
int i, len;
printf("Intro word:");
fgets(word, sizeof(word), stdin);
len = strlen(word);
if(word[len-1]=='\n')
word[--len] = '\0';
for(i = 0; i<len; i++){
sprintf(outword+i*2, "%02X", word[i]);
}
printf("%s\n", outword);
return 0;

In the terminal just write : $ mongod --version
I recommend you watch the video Web Application Projects & Web Deployment Projects on the ASP.NET website which explains the difference in great detail, it was quite helpful to me.
By the way, don't get confused by the title, a great part of the video explains the difference between website projects and web application projects and why Microsoft re-introduced Web application projects in Visual studio 2005 (as you probably already know, it originally shipped with only website projects then web application projects were added in SP1). A great video I highly recommend for anyone who wants to know the difference.
No need to use Carbon::today
because laravel uses function now() instead as a helper function
So to get any records that have been created today you can use the below code:
Model::whereDay('created_at', now()->day)->get();
You need to use whereDate
so created_at will be converted to date.
If you use <img> tags, then webkit based browsers won't display embedded bitmapped images.
For any kind of advanced SVG use, including the SVG inline offers by far the most flexibility.
Internet Explorer and Edge will resize the SVG correctly, but you must specify both the height and width.
You can add onclick, onmouseover, etc. inside the svg, to any shape in the SVG: onmouseover="top.myfunction(evt);"
You can also use web fonts in the SVG by including them in your regular style sheet.
Note: if you are exporting SVG's from Illustrator, the web font names will be wrong. You can correct this in your CSS and avoid messing around in the SVG. For example, Illustrator gives the wrong name to Arial, and you can fix it like this:
@font-face {
font-family: 'ArialMT';
src:
local('Arial'),
local('Arial MT'),
local('Arial Regular');
font-weight: normal;
font-style: normal;
}
All this works on any browser released since 2013.
For an example, see ozake.com. The whole site is made of SVG's except for the contact form.
Warning: Web fonts are imprecisely resized in Safari — and if you have lots of transitions from plain text to bold or italic, there may be a small amount of extra or missing space at the transition points. See my answer at this question for more information.
PowerShell one-liner to create a file in C:\Temp
to fill disk C: leaving only 10 MB:
[io.file]::Create("C:\temp\bigblob.txt").SetLength((gwmi Win32_LogicalDisk -Filter "DeviceID='C:'").FreeSpace - 10MB).Close
If you want to exclude the sub-directories, you can use
git diff <ref1>..<ref2> -- $(git diff <ref1>..<ref2> --name-only | grep -v /)
I'm using Rails 5 and the above answers work great; here's another way that also worked for me (the table name is :people
and the column name is :email_address
)
class AddIndexToEmailAddress < ActiveRecord::Migration[5.0]
def change
change_table :people do |t|
t.index :email_address, unique: true
end
end
end
>>> import random
>>> import string
>>> random.choice(string.ascii_lowercase)
'b'
Include the port number with the IP address.
For example:
http://19.18.20.101:5566
where 5566 is the port number.
There is another trick :
/* Padding on the sides of the table */
table th:first-child, .list td:first-child { padding-left: 28px; }
table th:last-child, .list td:last-child { padding-right: 28px; }
(Just saw it at my current job)
I prefer something more explicit:
component.html
<input #saveUserNameCheckBox
id="saveUserNameCheckBox"
type="checkbox"
[checked]="saveUsername"
(change)="onSaveUsernameChanged(saveUserNameCheckBox.checked)" />
component.ts
public saveUsername:boolean;
public onSaveUsernameChanged(value:boolean){
this.saveUsername = value;
}
You could code an ES5.1 helper function:
function setAttributes(el, attrs) {
Object.keys(attrs).forEach(key => el.setAttribute(key, attrs[key]));
}
Call it like this:
setAttributes(elem, { src: 'http://example.com/something.jpeg', height: '100%' });
For database :
USE db_name; SELECT @@character_set_database;
Possible. You can get commercial sport also.
JavaFXPorts is the name of the open source project maintained by Gluon that develops the code necessary for Java and JavaFX to run well on mobile and embedded hardware. The goal of this project is to contribute as much back to the OpenJFX project wherever possible, and when not possible, to maintain the minimal number of changes necessary to enable the goals of JavaFXPorts. Gluon takes the JavaFXPorts source code and compiles it into binaries ready for deployment onto iOS, Android, and embedded hardware. The JavaFXPorts builds are freely available on this website for all developers.
This can be done quite easily if you:
Use str
to convert the number into a string so that you can iterate over it.
Use a list comprehension to split the string into individual digits.
Use int
to convert the digits back into integers.
Below is a demonstration:
>>> n = 43365644
>>> [int(d) for d in str(n)]
[4, 3, 3, 6, 5, 6, 4, 4]
>>>
One tiny addition to JB Jansen's answer - in the main readdir()
loop I'd add this:
if (dir->d_type == DT_REG)
{
printf("%s\n", dir->d_name);
}
Just checking if it's really file, not (sym)link, directory, or whatever.

As described by RFC 6068, mailto allows you to specify subject and body, as well as cc fields. For example:
mailto:[email protected]?subject=Subject&body=message%20goes%20here
User doesn't need to click a link if you force it to be opened with JavaScript
window.location.href = "mailto:[email protected]?subject=Subject&body=message%20goes%20here";
Be aware that there is no single, standard way in which browsers/email clients handle mailto links (e.g. subject and body fields may be discarded without a warning). Also there is a risk that popup and ad blockers, anti-virus software etc. may silently block forced opening of mailto links.
import csv
from sys import argv
d = open("mydata.csv", "r")
db = []
for line in csv.reader(d):
db.append(line)
# the rest of your code with 'db' filled with your list of lists as rows and columbs of your csv file.
Simplify in a similar fashion to what you had in mind:
DO
$do$
BEGIN
IF NOT EXISTS (
SELECT FROM pg_catalog.pg_roles -- SELECT list can be empty for this
WHERE rolname = 'my_user') THEN
CREATE ROLE my_user LOGIN PASSWORD 'my_password';
END IF;
END
$do$;
(Building on @a_horse_with_no_name's answer and improved with @Gregory's comment.)
Unlike, for instance, with CREATE TABLE
there is no IF NOT EXISTS
clause for CREATE ROLE
(up to at least pg 12). And you cannot execute dynamic DDL statements in plain SQL.
Your request to "avoid PL/pgSQL" is impossible except by using another PL. The DO
statement uses plpgsql as default procedural language. The syntax allows to omit the explicit declaration:
DO [ LANGUAGE
lang_name
] code
...
lang_name
The name of the procedural language the code is written in. If omitted, the default isplpgsql
.
The top 2 answers (from Adam Robinson and Andrejs Cainikovs) are kinda, sorta correct, in that they do technically work, but their explanations are wrong and so could be misleading in many cases. For example, while the SQL_Latin1_General_CP1_CI_AS
collation will work in many cases, it should not be assumed to be the appropriate case-insensitive collation. In fact, given that the O.P. is working in a database with a case-sensitive (or possibly binary) collation, we know that the O.P. isn't using the collation that is the default for so many installations (especially any installed on an OS using US English as the language): SQL_Latin1_General_CP1_CI_AS
. Sure, the O.P. could be using SQL_Latin1_General_CP1_CS_AS
, but when working with VARCHAR
data, it is important to not change the code page as it could lead to data loss, and that is controlled by the locale / culture of the collation (i.e. Latin1_General vs French vs Hebrew etc). Please see point # 9 below.
The other four answers are wrong to varying degrees.
I will clarify all of the misunderstandings here so that readers can hopefully make the most appropriate / efficient choices.
Do not use UPPER()
. That is completely unnecessary extra work. Use a COLLATE
clause. A string comparison needs to be done in either case, but using UPPER()
also has to check, character by character, to see if there is an upper-case mapping, and then change it. And you need to do this on both sides. Adding COLLATE
simply directs the processing to generate the sort keys using a different set of rules than it was going to by default. Using COLLATE
is definitely more efficient (or "performant", if you like that word :) than using UPPER()
, as proven in this test script (on PasteBin).
There is also the issue noted by @Ceisc on @Danny's answer:
In some languages case conversions do not round-trip. i.e. LOWER(x) != LOWER(UPPER(x)).
The Turkish upper-case "I" is the common example.
No, collation is not a database-wide setting, at least not in this context. There is a database-level default collation, and it is used as the default for altered and newly created columns that do not specify the COLLATE
clause (which is likely where this common misconception comes from), but it does not impact queries directly unless you are comparing string literals and variables to other string literals and variables, or you are referencing database-level meta-data.
No, collation is not per query.
Collations are per predicate (i.e. something operand something) or expression, not per query. And this is true for the entire query, not just the WHERE
clause. This covers JOINs, GROUP BY, ORDER BY, PARTITION BY, etc.
No, do not convert to VARBINARY
(e.g.convert(varbinary, myField) = convert(varbinary, 'sOmeVal')
) for the following reasons:
_BIN2
if you are using SQL Server 2008 or newer, else you have no choice but to use one that ends with _BIN
. If the data is NVARCHAR
then it doesn't matter which locale you use as they are all the same in that case, hence Latin1_General_100_BIN2
always works. If the data is VARCHAR
, you must use the same locale that the data is currently in (e.g. Latin1_General
, French
, Japanese_XJIS
, etc) because the locale determines the code page that is used, and changing code pages can alter the data (i.e. data loss).CONVERT()
it will use the 30 default value. The danger is, if the string can be over 30 bytes, it will get silently truncated and you will likely get incorrect results from this predicate.No, LIKE
is not always case-sensitive. It uses the collation of the column being referenced, or the collation of the database if a variable is compared to a string literal, or the collation specified via the optional COLLATE
clause.
LCASE
is not a SQL Server function. It appears to be either Oracle or MySQL. Or possibly Visual Basic?
Since the context of the question is comparing a column to a string literal, neither the collation of the instance (often referred to as "server") nor the collation of the database have any direct impact here. Collations are stored per each column, and each column can have a different collation, and those collations don't need to be the same as the database's default collation or the instance's collation. Sure, the instance collation is the default for what a newly created database will use as its default collation if the COLLATE
clause wasn't specified when creating the database. And likewise, the database's default collation is what an altered or newly created column will use if the COLLATE
clause wasn't specified.
You should use the case-insensitive collation that is otherwise the same as the collation of the column. Use the following query to find the column's collation (change the table's name and schema name):
SELECT col.*
FROM sys.columns col
WHERE col.[object_id] = OBJECT_ID(N'dbo.TableName')
AND col.[collation_name] IS NOT NULL;
Then just change the _CS
to be _CI
. So, Latin1_General_100_CS_AS
would become Latin1_General_100_CI_AS
.
If the column is using a binary collation (ending in _BIN
or _BIN2
), then find a similar collation using the following query:
SELECT *
FROM sys.fn_helpcollations() col
WHERE col.[name] LIKE N'{CurrentCollationMinus"_BIN"}[_]CI[_]%';
For example, assuming the column is using Japanese_XJIS_100_BIN2
, do this:
SELECT *
FROM sys.fn_helpcollations() col
WHERE col.[name] LIKE N'Japanese_XJIS_100[_]CI[_]%';
For more info on collations, encodings, etc, please visit: Collations Info
Looking at the error message, part of the code of your Default.aspx
is :
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="AmeriaTestTask.Default" %>
but AmeriaTestTask.Default
does not exists, so you have to change it, most probably to the class defined in Default.aspx.cs. For example for web api aplications, the class defined in Global.asax.cs is : public class WebApiApplication : System.Web.HttpApplication
and in the asax page you have :
<%@ Application Codebehind="Global.asax.cs" Inherits="MyProject.WebApiApplication" Language="C#" %>
One way to do that is to use a counter:
ArrayList<Integer> list = new ArrayList<Integer>();
...
int size = list.size();
for (Integer i : list) {
...
if (--size == 0) {
// Last item.
...
}
}
Edit
Anyway, as Tom Hawtin said, it is sometimes better to use the "old" syntax when you need to get the current index information, by using a for
loop or the iterator
, as everything you win when using the Java5 syntax will be lost in the loop itself...
for (int i = 0; i < list.size(); i++) {
...
if (i == (list.size() - 1)) {
// Last item...
}
}
or
for (Iterator it = list.iterator(); it.hasNext(); ) {
...
if (!it.hasNext()) {
// Last item...
}
}
Yes you can view XML
files of an Android APK
file. There is a tool for this: android-apktool
It is a tool for reverse engineering 3rd party, closed, binary Android apps
How to do this on your Windows System:
Now copy the APK
file also in that directory and run the following command in your command prompt:
apktool d HelloWorld.apk ./HelloWorld
This will create a directory "HelloWorld
" in your current directory. Inside it you can find the AndroidManifest.xml
file in decrypted format, and you can also find other XML
files inside the "HelloWorld/res/layout"
directory.
Here HelloWorld.apk
is your Android APK file.
See the below screen shot for more information:
Jus use this code on Document.read()
$.fn.modal.Constructor.prototype.enforceFocus = function () {};
For future readers.
I wanted specific control over this issue, so this is what I did:
From a fragment or activity, hide your other views (that aren't needed while the keyboard is up), then restore them to solve this problem:
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
rootView.getWindowVisibleDisplayFrame(r);
int heightDiff = rootView.getRootView().getHeight() - (r.bottom - r.top);
if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
//ok now we know the keyboard is up...
view_one.setVisibility(View.GONE);
view_two.setVisibility(View.GONE);
} else {
//ok now we know the keyboard is down...
view_one.setVisibility(View.VISIBLE);
view_two.setVisibility(View.VISIBLE);
}
}
});
For compatibility with all browsers stick with .ico
.
.png is getting more and more support though as it is easier to create using multiple programs.
for .ico
<link rel="shortcut icon" href="http://example.com/myicon.ico" />
for .png, you need to specify the type
<link rel="icon" type="image/png" href="http://example.com/image.png" />
I think you're looking for export
- though I could be wrong.. I've never played with tcsh before. Use the following syntax:
export VARIABLE=value
I've always used .place()
for my tkinter widgets.
place syntax
You can specify the size of it just by changing the keyword arguments!
Of course, you will have to call .place()
again if you want to change it.
Works in python 3.8.2, if you're wondering.
Neither of the above answers worked for me, however this did
UPDATE:
As @doppleganger pointed out below, load is gone as of jQuery 3.0, so here's an updated version that uses on
. Please note this will actually work on jQuery 1.7+, so you can implement it this way even if you're not on jQuery 3.0 yet.
$('iframe').on('load', function() {
// do stuff
});

It boils down to adding android:stretchColumns="*"
to your TableLayout
root and setting android:layout_width="0dp"
to all the children in your TableRow
s.
<TableLayout
android:stretchColumns="*" // Optionally use numbered list "0,1,2,3,..."

typedef
is used to alias types; in this case you're aliasing FunctionFunc
to void(*)()
.
Indeed the syntax does look odd, have a look at this:
typedef void (*FunctionFunc) ( );
// ^ ^ ^
// return type type name arguments
No, this simply tells the compiler that the FunctionFunc
type will be a function pointer, it doesn't define one, like this:
FunctionFunc x;
void doSomething() { printf("Hello there\n"); }
x = &doSomething;
x(); //prints "Hello there"
File file = ...
byte[] data = ...
try{
FileOutputStream fos = FileOutputStream(file);
fos.write(data);
fos.flush();
fos.close();
}catch(Exception e){
}
but if the bytes array length is more than 1024 you should use loop to write the data.
This will be the answer:
moment.utc(moment(localdate)).format()
localdate = '2020-01-01 12:00:00'
moment(localdate)
//Moment<2020-01-01T12:00:00+08:00>
moment.utc(moment(localdate)).format()
//2020-01-01T04:00:00Z
If you do not want to use CURL, you could find some examples on stackoverflow, just like this one here: How do I send a POST request with PHP?. I would recommend you watch a few tutorials on how to use GET and POST methods within PHP or just take a look at the php.net manual here: httprequest::send. You can find a lot of tutorials: HTTP POST from PHP, without cURL and so on...
Html.CheckBoxFor
expects a Func<TModel, bool>
as the first parameter. Therefore your lambda must return a bool
, you are currently returning an instance of List<Checkboxes>
:
model => model.EmploymentType
You need to iterate over the List<Checkboxes>
to output each checkbox:
@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
@Html.HiddenFor(m => m.EmploymentType[i].Text)
@Html.CheckBoxFor(m => m.EmploymentType[i].Checked,
new { id = string.Format("employmentType_{0}", i) })
}
Using document.body.innerHTML = '';
does work! Just saying, if using HTML
(DOM
or on function
) you can usedocument.writeln('');
but only onClick
or onDoubleClick
:)
I think this is better, following the good practices of passing parameters to the query:
BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();
You can see it in the documentation, Laravel 5.5.
You can also use the Laravel scout and make it easier with search. Here is the documentation.
Using the Application Class
Depending on what you're doing in your initialization you could consider creating a new class that extends Application
and moving your initialization code into an overridden onCreate
method within that class.
public class MyApplicationClass extends Application {
@Override
public void onCreate() {
super.onCreate();
// TODO Put your application initialization code here.
}
}
The onCreate
in the application class is only called when the entire application is created, so the Activity restarts on orientation or keyboard visibility changes won't trigger it.
It's good practice to expose the instance of this class as a singleton and exposing the application variables you're initializing using getters and setters.
NOTE: You'll need to specify the name of your new Application class in the manifest for it to be registered and used:
<application
android:name="com.you.yourapp.MyApplicationClass"
Reacting to Configuration Changes [UPDATE: this is deprecated since API 13; see the recommended alternative]
As a further alternative, you can have your application listen for events that would cause a restart – like orientation and keyboard visibility changes – and handle them within your Activity.
Start by adding the android:configChanges
node to your Activity's manifest node
<activity android:name=".MyActivity"
android:configChanges="orientation|keyboardHidden"
android:label="@string/app_name">
or for Android 3.2 (API level 13) and newer:
<activity android:name=".MyActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:label="@string/app_name">
Then within the Activity override the onConfigurationChanged
method and call setContentView
to force the GUI layout to be re-done in the new orientation.
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
setContentView(R.layout.myLayout);
}
Two of the most common
First way :
let jsonData = require('./JsonFile.json')
let jsonData = require('./JsonFile')
// if we omitting .json also works
OR
import jsonData from ('./JsonFile.json')
Second way :
1) synchronously
const fs = require('fs')
let jsonData = JSON.parse(fs.readFileSync('JsonFile.json', 'utf-8'))
2) asynchronously
const fs = require('fs')
let jsonData = {}
fs.readFile('JsonFile.json', 'utf-8', (err, data) => {
if (err) throw err
jsonData = JSON.parse(data)
})
Note: 1) if we JsonFile.json is changed, we not get the new data, even if we re run require('./JsonFile.json')
2) The fs.readFile or fs.readFileSync will always re read the file, and get changes
I have faced the same problem and I solved as give db_owner permission too to the Database user.
These are good answers but detached from a full answer as to how you would get a form to send data and handle that response. This will demonstrate how to add a member to a list with v3.0 of the API from an HTML page via jquery .ajax()
.
In Mailchimp:
zipcode
as a custom field in the list BEFORE I did the API call.create
method which requires the use of HTTP POST
requests. There are other options in here that require PUT
if you want to be able to modify/delete subs.HTML:
<form id="pfb-signup-submission" method="post">
<div class="sign-up-group">
<input type="text" name="pfb-signup" id="pfb-signup-box-fname" class="pfb-signup-box" placeholder="First Name">
<input type="text" name="pfb-signup" id="pfb-signup-box-lname" class="pfb-signup-box" placeholder="Last Name">
<input type="email" name="pfb-signup" id="pfb-signup-box-email" class="pfb-signup-box" placeholder="[email protected]">
<input type="text" name="pfb-signup" id="pfb-signup-box-zip" class="pfb-signup-box" placeholder="Zip Code">
</div>
<input type="submit" class="submit-button" value="Sign-up" id="pfb-signup-button"></a>
<div id="pfb-signup-result"></div>
</form>
Key things:
<form>
a unique ID and don't forget the method="post"
attribute so the form works. #signup-result
is where you will deposit the feedback from the PHP script.PHP:

Key things:
CURLOPT_USERPWD
handles the API key and Mailchimp doesn't really show you how to do this. CURLOPT_RETURNTRANSFER
gives us the response in such a way that we can send it back into the HTML page with the .ajax()
success
handler.json_encode
on the data you received.JS:
// Signup form submission
$('#pfb-signup-submission').submit(function(event) {
event.preventDefault();
// Get data from form and store it
var pfbSignupFNAME = $('#pfb-signup-box-fname').val();
var pfbSignupLNAME = $('#pfb-signup-box-lname').val();
var pfbSignupEMAIL = $('#pfb-signup-box-email').val();
var pfbSignupZIP = $('#pfb-signup-box-zip').val();
// Create JSON variable of retreived data
var pfbSignupData = {
'firstname': pfbSignupFNAME,
'lastname': pfbSignupLNAME,
'email': pfbSignupEMAIL,
'zipcode': pfbSignupZIP
};

console.log(results);

Key things:
JSON
data is VERY touchy on transfer. Here, I am putting it into an array and it looks easy. If you are having problems, it is likely because of how your JSON data is structured. Check this out!_POST
global variable. In this case it will be _POST['email']
, _POST['firstname']
, etc. But you could name them whatever you want - just remember what you name the keys of the data
part of your JSON transfer is how you access them in PHP.The easiest method without using javaScript is to put all your <select> dropdown inside a <form> tag and use form reset button. Example:
<form>
<select>
<option>one</option>
<option>two</option>
<option selected>three</option>
</select>
<input type="reset" value="Reset" />
</form>
Or, using JavaScript, it can be done in following way:
HTML Code:
<select>
<option selected>one</option>
<option>two</option>
<option>three</option>
</select>
<button id="revert">Reset</button>
And JavaScript code:
const button = document.getElementById("revert");
const options = document.querySelectorAll('select option');
button.onclick = () => {
for (var i = 0; i < options.length; i++) {
options[i].selected = options[i].defaultSelected;
}
}
Both of these methods will work if you have multiple selected items or single selected item.
it worked. Just modified it
global $woocommerce, $post;
$order = new WC_Order($post->ID);
//to escape # from order id
$order_id = trim(str_replace('#', '', $order->get_order_number()));
you can use
SELECT timestamp, value, card
FROM my_table
ORDER BY timestamp DESC
LIMIT 1
assuming you want also to sort by timestamp
?
If you're using a jupyter notebook, I found this to be the simplest solution for one off cases. Basically convert the numpy array to a list and then to a string and then print. This has the benefit of keeping the comma separators in the array, whereas using numpyp.printoptions(threshold=np.inf)
does not:
import numpy as np
print(str(np.arange(10000).reshape(250,40).tolist()))
about:config -> security.fileuri.strict_origin_policy -> false
Note before you read the rest: The shell script shown here is certainly not safe to use and well tested. Use at your own risk!
I wrote a bash script to accomplish that task. Suppose your library is lib1 and the one you need to include some symbols from is lib2. The script now runs in a loop, where it first checks which undefined symbols from lib1 can be found in lib2. It then extracts the corresponding object files from lib2 with ar
, renames them a bit, and puts them into lib1. Now there may be more missing symbols, because the stuff you included from lib2 needs other stuff from lib2, which we haven't included yet, so the loop needs to run again. If after some passes of the loop there are no changes anymore, i.e. no object files from lib2 added to lib1, the loop can stop.
Note, that the included symbols are still reported as undefined by nm
, so I'm keeping track of the object files, that were added to lib1, themselves, in order to determine whether the loop can be stopped.
#! /bin/bash
lib1="$1"
lib2="$2"
if [ ! -e $lib1.backup ]; then
echo backing up
cp $lib1 $lib1.backup
fi
remove_later=""
new_tmp_file() {
file=$(mktemp)
remove_later="$remove_later $file"
eval $1=$file
}
remove_tmp_files() {
rm $remove_later
}
trap remove_tmp_files EXIT
find_symbols() {
nm $1 $2 | cut -c20- | sort | uniq
}
new_tmp_file lib2symbols
new_tmp_file currsymbols
nm $lib2 -s --defined-only > $lib2symbols
prefix="xyz_import_"
pass=0
while true; do
((pass++))
echo "Starting pass #$pass"
curr=$lib1
find_symbols $curr "--undefined-only" > $currsymbols
changed=0
for sym in $(cat $currsymbols); do
for obj in $(egrep "^$sym in .*\.o" $lib2symbols | cut -d" " -f3); do
echo " Found $sym in $obj."
if [ -e "$prefix$obj" ]; then continue; fi
echo " -> Adding $obj to $lib1"
ar x $lib2 $obj
mv $obj "$prefix$obj"
ar -r -s $lib1 "$prefix$obj"
remove_later="$remove_later $prefix$obj"
((changed=changed+1))
done
done
echo "Found $changed changes in pass #$pass"
if [[ $changed == 0 ]]; then break; fi
done
I named that script libcomp
, so you can call it then e.g. with
./libcomp libmylib.a libwhatever.a
where libwhatever is where you want to include symbols from. However, I think it's safest to copy everything into a separate directory first. I wouldn't trust my script so much (however, it worked for me; I could include libgsl.a into my numerics library with that and leave out that -lgsl compiler switch).
For a simple java String
Array you should try
String arr_str [] = { "value1`", "value2", "value3" };
JSONArray arr_strJson = new JSONArray(Arrays.asList(arr_str));
System.out.println(arr_strJson.toString());
If you have an Generic ArrayList of type String like ArrayList<String>
. then you should try
ArrayList<String> obj_list = new ArrayList<>();
obj_list.add("value1");
obj_list.add("value2");
obj_list.add("value3");
JSONArray arr_strJson = new JSONArray(obj_list));
System.out.println(arr_strJson.toString());
What specific errors are you seeing?
Something like this could work better:
<script type="text/javascript">
//now add markers
@foreach (var item in Model) {
<text>
var markerlatLng = new google.maps.LatLng(@Model.Latitude, @Model.Longitude);
var title = '@(Model.Title)';
var description = '@(Model.Description)';
var contentString = '<h3>' + title + '</h3>' + '<p>' + description + '</p>'
</text>
}
</script>
Note that you need the magical <text>
tag after the foreach
to indicate that Razor should switch into markup mode.
I find the best (and least frustrating) path is to start with Allow from All
, then, when you know it will work that way, scale it back to the more secure Allow from 127.0.0.1
or Allow from ::1
(localhost).
As long as your firewall is configured properly, Allow from all
shouldn't cause any problems, but it is better to only allow from localhost if you don't need other computers to be able to access your site.
Don't forget to restart Apache whenever you make changes to httpd.conf. They will not take effect until the next start.
Hopefully this is enough to get you started, there is lots of documentation available online.
On a branch I was able to do it like this (for the last 4 commits)
git checkout my_branch
git reset --soft HEAD~4

git push --force origin my_branch
Look at SELECT INTO. This will create a new table for you, which can be temporary if you want by prefixing the table name with a pound sign (#).
For example, you can do:
SELECT *
INTO #YourTempTable
FROM YourReportQuery
Watch that your file name doesn't have :
in them either. I found that I had to mv blah-07-08-17-02:69.txt no_colons.txt
and then scp no-colons.txt server:
then don't forget to mv
back on the server. Just in case this was an issue.
Here is a Bundle Transform that will replace css urls with urls relative to that css file. Just add it to your bundle and it should fix the issue.
public class CssUrlTransform: IBundleTransform
{
public void Process(BundleContext context, BundleResponse response) {
Regex exp = new Regex(@"url\([^\)]+\)", RegexOptions.IgnoreCase | RegexOptions.Singleline);
foreach (FileInfo css in response.Files) {
string cssAppRelativePath = css.FullName.Replace(context.HttpContext.Request.PhysicalApplicationPath, context.HttpContext.Request.ApplicationPath).Replace(Path.DirectorySeparatorChar, '/');
string cssDir = cssAppRelativePath.Substring(0, cssAppRelativePath.LastIndexOf('/'));
response.Content = exp.Replace(response.Content, m => TransformUrl(m, cssDir));
}
}
private string TransformUrl(Match match, string cssDir) {
string url = match.Value.Substring(4, match.Length - 5).Trim('\'', '"');
if (url.StartsWith("http://") || url.StartsWith("data:image")) return match.Value;
if (!url.StartsWith("/"))
url = string.Format("{0}/{1}", cssDir, url);
return string.Format("url({0})", url);
}
}
Use list comprehensions if you want a single line solution. The following code returns a list containing the url_string when it has the extensions .doc, .pdf and .xls or returns empty list when it doesn't contain the extension.
print [url_string for extension in extensionsToCheck if(extension in url_string)]
NOTE: This is only to check if it contains or not and is not useful when one wants to extract the exact word matching the extensions.
Three problems here:
String.matches()
- if the API is there, use itI recommend you use code like this:
public boolean matches(String regex) {
regex = "^.*" + regex + ".*$"; // pad with regex to allow partial matching
System.out.println("abcABC ".matches(regex));
return "abcABC ".matches(regex);
}
public static void main(String[] args) {
HowEasy words = new HowEasy();
words.matches("[a-zA-Z]+"); // added "+" (ie 1-to-n of) to character class
}
Here is my simple and working function to generate a Bitmap! I Use ZXing1.3.jar only! I've also set Correction Level to High!
PS: x and y are reversed, it's normal, because bitMatrix reverse x and y. This code works perfectly with a square image.
public static Bitmap generateQrCode(String myCodeText) throws WriterException {
Hashtable<EncodeHintType, ErrorCorrectionLevel> hintMap = new Hashtable<EncodeHintType, ErrorCorrectionLevel>();
hintMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.H); // H = 30% damage
QRCodeWriter qrCodeWriter = new QRCodeWriter();
int size = 256;
ByteMatrix bitMatrix = qrCodeWriter.encode(myCodeText,BarcodeFormat.QR_CODE, size, size, hintMap);
int width = bitMatrix.width();
Bitmap bmp = Bitmap.createBitmap(width, width, Bitmap.Config.RGB_565);
for (int x = 0; x < width; x++) {
for (int y = 0; y < width; y++) {
bmp.setPixel(y, x, bitMatrix.get(x, y)==0 ? Color.BLACK : Color.WHITE);
}
}
return bmp;
}
EDIT
It's faster to use bitmap.setPixels(...) with a pixel int array instead of bitmap.setPixel one by one:
BitMatrix bitMatrix = writer.encode(inputValue, BarcodeFormat.QR_CODE, size, size);
int width = bitMatrix.getWidth();
int height = bitMatrix.getHeight();
int[] pixels = new int[width * height];
for (int y = 0; y < height; y++) {
int offset = y * width;
for (int x = 0; x < width; x++) {
pixels[offset + x] = bitMatrix.get(x, y) ? BLACK : WHITE;
}
}
bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
bitmap.setPixels(pixels, 0, width, 0, 0, width, height);
Actually I would like to comment, but I am not authorised yet. That is why that pretend to be next answer while it is not.
import React from 'react';
import logo from './logo.png'; // Tell Webpack this JS file uses this image
console.log(logo); // /logo.84287d09.png
function Header() {
// Import result is the URL of your image
return <img src={logo} alt="Logo" />;
I would like to continue that path. That works smoothly when one has picture one can simple insert. In my case that is slightly more complex: I have to map several pictures it. So far the only workable way to do this I found is as follows
import upperBody from './upperBody.png';
import lowerBody from './lowerBody.png';
import aesthetics from './aesthetics.png';
let obj={upperBody:upperBody, lowerBody:lowerBody, aesthetics:aesthetics, agility:agility, endurance:endurance}
{Object.keys(skills).map((skill) => {
return ( <img className = 'icon-size' src={obj[skill]}/>
So, my question is whether are there simplier ways to process these images? Needless to say that in more general case number of files that must be literally imported could be huge and number of keys in object as well. (Object in that code is involved clearly to refer by names -its keys) In my case require-related procedures have not worked - loaders generated errors of strange kind during installation and shown no mark of working; and require by itself has not worked neither.
The type() function can return the type of an object or create a new type,
for example, we can create a Hi class with the type() function and do not need to use this way with class Hi(object):
def func(self, name='mike'):
print('Hi, %s.' % name)
Hi = type('Hi', (object,), dict(hi=func))
h = Hi()
h.hi()
Hi, mike.
type(Hi)
type
type(h)
__main__.Hi
In addition to using type() to create classes dynamically, you can control creation behavior of class and use metaclass.
According to the Python object model, the class is the object, so the class must be an instance of another certain class. By default, a Python class is instance of the type class. That is, type is metaclass of most of the built-in classes and metaclass of user-defined classes.
class ListMetaclass(type):
def __new__(cls, name, bases, attrs):
attrs['add'] = lambda self, value: self.append(value)
return type.__new__(cls, name, bases, attrs)
class CustomList(list, metaclass=ListMetaclass):
pass
lst = CustomList()
lst.add('custom_list_1')
lst.add('custom_list_2')
lst
['custom_list_1', 'custom_list_2']
Magic will take effect when we passed keyword arguments in metaclass, it indicates the Python interpreter to create the CustomList through ListMetaclass. new (), at this point, we can modify the class definition, for example, and add a new method and then return the revised definition.
It might be strange answer for codesign issue in Xcode 9.0. I was receiving this error too and did not know what to be done, because everything was correct.
I went to the keychain, I had the login option "unlocked". I locked it and compiled my build again. Xcode itself asked me to open access keychain. I gave access and it worked.
Steps were:
Even though your JDK in eclipse is 1.7, you need to make sure eclipse compilance level also set to 1.7. You can check compilance level--> Window-->Preferences--> Java--Compiler--compilance level.
Unsupported major minor error happens in cases where compilance level doesn't match with runtime.

Note the single-quotes and wildcard characters. I just spent 30 minutes figuring out something similar.
There is the Mono Project from Novell that will allow you to run ASP.Net on Apache.
I've seen many variants of this problem. One of the main differences (that determines the difficulty) is whether there is some centralized attempt to have a "smart and efficient system" that would have load balancing (e.g., send more idle elevators to lobby in morning). If that is the case, the design will include a whole subsystem with really fun design.
A full design is obviously too much to present here and there are many altenatives. The breadth is also not clear. In an interview, they'll try to figure out how you would think. However, these are some of the things you would need:
Representation of the central controller (assuming there is one).
Representations of elevators
Representations of the interface units of the elevator (these may be different from elevator to elevator). Obviously also call buttons on every floor, etc.
Representations of the arrows or indicators on each floor (almost a "view" of the elevator model).
Representation of a human and cargo (may be important for factoring in maximal loads)
Representation of the building (in some cases, as certain floors may be blocked at times, etc.)
I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)
The screen you show is DateTimeSettings
. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time";
and also to Settings.System.AUTO_TIME
This settings is observed by an observed called mAutoTimeObserver
in the 2 network ServiceStateTracker
s:
GsmServiceStateTracker
and CdmaServiceStateTracker
.
Both implementations call a method called revertToNitz()
when the settings becomes true.
Apparently NITZ is the equivalent of NTP in the carrier world.
Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz()
.
Unfortunately, I haven't found a mechanism to get the network time.
If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTracker
s implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime
.
Copy the installation files into your hard drive. Rename the installer file name to vs_professional.exe for professional edition. Enjoy.
In my case it was trying to call JSON.parse() on an AJAX variable before the XHRResponse came back. EG:
var response = $.get(URL that returns a valid JSON string);
var data = JSON.parse(response.responseText);
I replaced that with an example out of the jQuery site for $.get:
<script type="text/javascript">
var jqxhr = $.get( "https://jira.atlassian.com/rest/api/2/project", function() {
alert( "success" );
})
.done(function() {
//insert code to assign the projects from Jira to a div.
jqxhr = jqxhr.responseJSON;
console.log(jqxhr);
var div = document.getElementById("products");
for (i = 0; i < jqxhr.length; i++) {
console.log(jqxhr[i].name);
div.innerHTML += "<b>Product: " + jqxhr[i].name + "</b><BR/>Key: " + jqxhr[i].key + "<BR/>";
}
console.log(div);
alert( "second success" );
})
.fail(function() {
alert( "error" );
})
.always(function() {
alert( "finished" );
});
// Perform other work here ...
// Set another completion function for the request above
jqxhr.always(function() {
alert( "second finished" );
});
</script>
git stash pop
applies the top stashed element and removes it from the stack. git stash apply
does the same, but leaves it in the stash stack.
This is working for me (i use laravel 5.6).
$collection = MyModel::all()->groupBy('column');
If you want to convert the collection to plain php array, you can use toArray()
$array = MyModel::all()->groupBy('column')->toArray();
As ping
works, but telnet
to port 80
does not, the HTTP port 80
is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?).
You need to add some code to your python program, that handles the proxy, like described here:
Here is something you can do with a two step approach and awk:
A=http://www.suepearson.co.uk/product/174/71/3816/
echo $A|awk '
{
var=gensub(///,"||",3,$0) ;
sub(/\|\|.*/,"",var);
print var
}'
Output: http://www.suepearson.co.uk
Hope that helps!

- Collect (Action) - Return all the elements of the dataset as an array at the driver program. This is usually useful after a filter or other operation that returns a sufficiently small subset of the data.
select(*cols) (transformation) - Projects a set of expressions and returns a new DataFrame.
Parameters: cols – list of column names (string) or expressions (Column). If one of the column names is ‘*’, that column is expanded to include all columns in the current DataFrame.**
df.select('*').collect() [Row(age=2, name=u'Alice'), Row(age=5, name=u'Bob')] df.select('name', 'age').collect() [Row(name=u'Alice', age=2), Row(name=u'Bob', age=5)] df.select(df.name, (df.age + 10).alias('age')).collect() [Row(name=u'Alice', age=12), Row(name=u'Bob', age=15)]
Execution select(column-name1,column-name2,etc)
method on a dataframe, returns a new dataframe which holds only the columns which were selected in the select()
function.
e.g. assuming df
has several columns including "name" and "value" and some others.
df2 = df.select("name","value")
df2
will hold only two columns ("name" and "value") out of the entire columns of df
df2 as the result of select
will be in the executors and not in the driver (as in the case of using collect()
)
df.printSchema()
# root
# |-- age: long (nullable = true)
# |-- name: string (nullable = true)
# Select only the "name" column
df.select("name").show()
# +-------+
# | name|
# +-------+
# |Michael|
# | Andy|
# | Justin|
# +-------+
You can running collect()
on a dataframe (spark docs)
>>> l = [('Alice', 1)]
>>> spark.createDataFrame(l).collect()
[Row(_1=u'Alice', _2=1)]
>>> spark.createDataFrame(l, ['name', 'age']).collect()
[Row(name=u'Alice', age=1)]
To print all elements on the driver, one can use the collect() method to first bring the RDD to the driver node thus: rdd.collect().foreach(println). This can cause the driver to run out of memory, though, because collect() fetches the entire RDD to a single machine; if you only need to print a few elements of the RDD, a safer approach is to use the take(): rdd.take(100).foreach(println).
return Dns.GetHostEntry(Dns.GetHostName()).AddressList.FirstOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork);
Simple single line of code that returns the first internal IPV4 address or null if there are none. Added as a comment above, but may be useful to someone (some solutions above will return multiple addresses that need further filtering).
It's also easy to return loopback instead of null I guess with:
return Dns.GetHostEntry(Dns.GetHostName()).AddressList.FirstOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork) ?? new IPAddress( new byte[] {127, 0, 0, 1} );
Bit of an amalgamation of the stuff above. But here's my crack at it.

This is the way to include an external javascript file to you HTML markup.
<script type="text/javascript" src="/js/external-javascript.js"></script>
Where external-javascript.js
is the external file to be included. Make sure the path and the file name are correct while you including it.
<a href="javascript:showCountry('countryCode')">countryCode</a>
The above mentioned method is correct for anchor tags and will work perfectly. But for other elements you should specify the event explicitly.
Example:
<select name="users" onChange="showUser(this.value)">
Thanks, XmindZ
Reasonably portable, non-framework way of having your script set a function to run at load time:
if(window.attachEvent) {
window.attachEvent('onload', yourFunctionName);
} else {
if(window.onload) {
var curronload = window.onload;
var newonload = function(evt) {
curronload(evt);
yourFunctionName(evt);
};
window.onload = newonload;
} else {
window.onload = yourFunctionName;
}
}
I think you just need;
List<string> list = new List<string>();
list.Add("hai");
There is a difference between
List<string> list;
and
List<string> list = new List<string>();
When you didn't use new
keyword in this case, your list
didn't initialized. And when you try to add it hai
, obviously you get an error.

Now after opening ipython notebook with the usual command for Python2.7, Python3.3 is also available when creating a new notebook.
Worked for me:
Download package (see links below), name it lp.cab and place it to your C:
drive
Run the following commands as Administrator:
2.1 installing new language
dism /Online /Add-Package /PackagePath:C:\lp.cab
2.2 get installed packages
dism /Online /Get-Packages
2.3 remove original package
dism /Online /Remove-Package /PackageName:Microsoft-Windows-Client-LanguagePack-Package~31bf3856ad364e35~amd64~ru-RU~10.0.10240.16384
If you don't know which is your original package you can check your installed packages with this line
dism /Online /Get-Packages | findstr /c:"LanguagePack"

All you need to do is Run your terminal as Administrator. in my case, that's how I solve my problem.
You can use Collections.binarySearch to find the element, then call remove on the returned index.
See the documentation for Collections.binarySearch here: http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Collections.html#binarySearch%28java.util.List,%20java.lang.Object%29
This would require the ArrayTest object to have .equals implemented though. You would also need to call Collections.sort to sort the list. Finally, ArrayTest would have to implement the Comparable interface, so that binarySearch would run correctly.
This is the "proper" way to do it in Java. If you are just looking to solve the problem in a quick and dirty fashion, then you can just iterate over the elements and remove the one with the attribute you are looking for.
This is just an explanation not addressed in other answers
At least in recent versions of Mysql, your first query is not committed.
If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.
What's going on?
When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.
So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE
, UPDATE
, INSERT
or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT
) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).
That's why the solution involves declaring handlers to immediately ROLLBACK
when an error happens.
Extra
Inside the handler you can also re-raise the error using RESIGNAL
, otherwise the stored procedure executes "Successfully"
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
ROLLBACK;
RESIGNAL;
END;
START TRANSACTION;
#.. Query 1 ..
#.. Query 2 ..
#.. Query 3 ..
COMMIT;
END
For example you want to find a mean of each column in matrix. Let's create the following matrix
mat2 = np.array([1,5,6,7,3,0,3,5,9,10,8,0], dtype=np.float64).reshape(3, 4)
The function for mean is
def my_mean(x):
return sum(x)/len(x)
To do what is needed and store result in colon vector 'results'
results = np.zeros(4)
for i in range(0, 4):
mat2[:, i] = my_mean(mat2[:, i])
results = mat2[1,:]
The results are: array([4.33333333, 5. , 5.66666667, 4. ])
You can check like this:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var list = ["bad", "words", "include"]
var sentence = $("#comments_text").val()
$.each(list, function( index, value ) {
if (sentence.indexOf(value) > -1) {
console.log(value)
}
});
});
</script>
</head>
<body>
<input id="comments_text" value="This is a bad, with include test">
</body>
</html>
For me, this is what worked using Apache HttpComponents ~ HttpClient 4.x:
KeyStore keyStore = KeyStore.getInstance("PKCS12");
FileInputStream instream = new FileInputStream(new File("client-p12-keystore.p12"));
try {
keyStore.load(instream, "helloworld".toCharArray());
} finally {
instream.close();
}
// Trust own CA and all self-signed certs
SSLContext sslcontext = SSLContexts.custom()
.loadKeyMaterial(keyStore, "helloworld".toCharArray())
//.loadTrustMaterial(trustStore, new TrustSelfSignedStrategy()) //custom trust store
.build();
// Allow TLSv1 protocol only
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
sslcontext,
new String[] { "TLSv1" },
null,
SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); //TODO
CloseableHttpClient httpclient = HttpClients.custom()
.setHostnameVerifier(SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER) //TODO
.setSSLSocketFactory(sslsf)
.build();
try {
HttpGet httpget = new HttpGet("https://localhost:8443/secure/index");
System.out.println("executing request" + httpget.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httpget);
try {
HttpEntity entity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (entity != null) {
System.out.println("Response content length: " + entity.getContentLength());
}
EntityUtils.consume(entity);
} finally {
response.close();
}
} finally {
httpclient.close();
}
The P12 file contains the client certificate and client private key, created with BouncyCastle:
public static byte[] convertPEMToPKCS12(final String keyFile, final String cerFile,
final String password)
throws IOException, CertificateException, KeyStoreException, NoSuchAlgorithmException,
NoSuchProviderException
{
// Get the private key
FileReader reader = new FileReader(keyFile);
PEMParser pem = new PEMParser(reader);
PEMKeyPair pemKeyPair = ((PEMKeyPair)pem.readObject());
JcaPEMKeyConverter jcaPEMKeyConverter = new JcaPEMKeyConverter().setProvider("BC");
KeyPair keyPair = jcaPEMKeyConverter.getKeyPair(pemKeyPair);
PrivateKey key = keyPair.getPrivate();
pem.close();
reader.close();
// Get the certificate
reader = new FileReader(cerFile);
pem = new PEMParser(reader);
X509CertificateHolder certHolder = (X509CertificateHolder) pem.readObject();
java.security.cert.Certificate x509Certificate =
new JcaX509CertificateConverter().setProvider("BC")
.getCertificate(certHolder);
pem.close();
reader.close();
// Put them into a PKCS12 keystore and write it to a byte[]
ByteArrayOutputStream bos = new ByteArrayOutputStream();
KeyStore ks = KeyStore.getInstance("PKCS12", "BC");
ks.load(null);
ks.setKeyEntry("key-alias", (Key) key, password.toCharArray(),
new java.security.cert.Certificate[]{x509Certificate});
ks.store(bos, password.toCharArray());
bos.close();
return bos.toByteArray();
}
For checking spaces just with bash:
[[ "$str" = "${str% *}" ]] && echo "no spaces" || echo "has spaces"
First we need to find a Button
:
Button mButton = (Button) findViewById(R.id.my_button);
After that, you must implement View.OnClickListener
and there you should find the TextView
and execute the method setText
:
mButton.setOnClickListener(new View.OnClickListener {
public void onClick(View v) {
final TextView mTextView = (TextView) findViewById(R.id.my_text_view);
mTextView.setText("Some Text");
}
});
matrix.size
according to the numpy docs returns the Number of elements in the array.
Hope that helps.
Here are the instructions for Windows users on connecting to a RPi by using just an Ethernet cable and a DHCP server. There is no need for a cross over cable, as the RPi can handle it. I have a blog post that documents this with pictures here which may be easier to follow.
Downloads
Download the DHCP Server for Windows (download link is here). Unzip the zip file and open the dhcpwiz application, which will configure the DHCP server.
DHCP Server Configuration
Hit next on the first screen.
On the second screen, look for a "Local Area Connection" row and verify its IP address is 0.0.0.0
and its status is enabled
. Connect the Ethernet cable from the RPi to your laptop, and turn on the Pi. Hit refresh on this screen until the IP address changes to 169.254.*.*
. If it is anything else then you should alter your network settings for the Local Area Connection (make sure it is not a static IP/DNS). Click on this Local Area Connection row and hit next.
Check HTTP (Web Server)
. This makes it much more easy to locate the RPi's IP address. Hit Next.
Take the defaults and hit Next until you get to the Writing the INI file
screen. Check Overwrite existing file
and hit the Write INI file
button. Then hit Next.
On the final screen, check Run DHCP server immediately
and hit `Finish.
DHCP Server and Obtaining the IP Address of your Raspberry PI
This launches the actual DHCP server, using the configuration you just created in the previous wizard. Click the Continue as tray app
button, and the DHCP server will be minimized to your system tray.
Anywhere from 1 second to 5 minutes from now you will see an alert on the system tray with your laptop and your RPi's new IP address. This alert is really quick and you will probably miss it. Normally your RPi's IP is 169.254.0.2
, but it could be *.01
or even something else. It is easier to access the DHCP server's web UI at http://localhost/dhcpstatus.xml. This will list the hostname as "raspberrypi" with its IP address.
Now you can putty or remote desktop into your RPi, and configure its wireless settings or whatever you want to do.
Trouble shooting
This can be somewhat finicky. I've had my connection appear to drop and have been unable to SSH back in using the IP address. Normally, I can restart the Pi and get the IP address again. Sometimes I have to restart both the RPi and the DHCP server. Sometimes I have to do this multiple times. At one point when I wasn't getting a connection for 15 minutes, I copied all of the files in the dhcpsrv2.5.1 folder to a new folder and tried again; it immediately worked.
Adding to @CR Rollyson answer,
In case if you have a collapsible div which has a min-height attribute, it will also cause the jerking. Try removing that attribute from directly collapsible div. Use it in the child div of the collapsible div.
<div class="form-group">
<a for="collapseOne" data-toggle="collapse" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">+ Not Jerky</a>
<div class="collapse" id="collapseOne" style="padding: 0;">
<textarea class="form-control" rows="4" style="padding: 20px;">No padding on animated element. Padding on child.</textarea>
</div>
</div>
A POSIX compliant one using the s

Its just like creating a WAR
file of your project, you can do it in several ways (from Eclipse, command line, maven).
If you want to do from command line, the command is
jar -cvf my_web_app.war *
Which means, "compress everything in this directory into a file named my_web_app.war" (c=create, v=verbose, f=file)
If a
is your array:
In [11]: a[:,:2]
Out[11]:
array([[-0.57098887, -0.4274751 ],
[-0.22279713, -0.51723555],
[ 0.67492385, -0.69294472],
[ 0.41086611, 0.26374238]])
i had the same problem long time ago, and it fixed it using
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-15">
<img title="<a href="javascript:alert('hello world')">The Link</a>" />
Use:
#include <windows.h>
Sleep(sometime_in_millisecs); // Note uppercase S
And here's a small example that compiles with MinGW and does what it says on the tin:
#include <windows.h>
#include <stdio.h>
int main() {
printf( "starting to sleep...\n" );
Sleep(3000); // Sleep three seconds
printf("sleep ended\n");
}
It is a security risk to avoid host key checking.
JSch uses HostKeyRepository interface and its default implementation KnownHosts class to manage this. You can provide an alternate implementation that allows specific keys by implementing HostKeyRepository. Or you could keep the keys that you want to allow in a file in the known_hosts format and call
jsch.setKnownHosts(knownHostsFileName);
Or with a public key String as below.
String knownHostPublicKey = "mysite.com ecdsa-sha2-nistp256 AAAAE............/3vplY";
jsch.setKnownHosts(new ByteArrayInputStream(knownHostPublicKey.getBytes()));
see Javadoc for more details.
This would be a more secure solution.
Jsch is open source and you can download the source from here. In the examples folder, look for KnownHosts.java to know more details.
The root problem is that WebKit browsers (Safari and Chrome) load JavaScript and CSS information in parallel. Thus, JavaScript may execute before the styling effects of CSS have been computed, returning the wrong answer. In jQuery, I've found that the solution is to wait until document.readyState == 'complete', .e.g.,
jQuery(document).ready(function(){
if (jQuery.browser.safari && document.readyState != "complete"){
//console.info('ready...');
setTimeout( arguments.callee, 100 );
return;
}
... (rest of function)
As far as width and height goes... depending on what you are doing you may want offsetWidth and offsetHeight, which include things like borders and padding.
If we need to show different type of view in list-view then its good to use getViewTypeCount() and getItemViewType() in adapter instead of toggling a view VIEW.GONE and VIEW.VISIBLE can be very expensive task inside getView() which will affect the list scroll.
Please check this one for use of getViewTypeCount() and getItemViewType() in Adapter.

If you are able to use NOW() this would be simplest form:
SELECT * FROM `fab_scheduler` WHERE eventdate>=(NOW() - INTERVAL 1 DAY)) AND eventdate<NOW() ORDER BY eventdate DESC;
With MySQL 5.6+ query abowe should do. Depending on sql server, You may be required to use CURRDATE()
instead of NOW()
- which is alias for DATE(NOW())
and will return only date part of datetime
data type;
The asterisk (*) means "zero or more of the previous item".
If you want to match any single character use
sed -i 's/string-./string-0/g' file.txt
If you want to match any string (i.e. any single character zero or more times) use
sed -i 's/string-.*/string-0/g' file.txt
Wget currently only supports x-www-form-urlencoded data. --post-file
is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example
.
--post-data
and --post-file
work the same way: the only difference is that --post-data
allows you to specify the data in the command line, while --post-file
allows you to specify the path of the file that contain the data to send.
Here's the documentation:
--post-data=string
--post-file=file
Use POST as the method for all HTTP requests and send the specified data
in the request body. --post-data sends string as data, whereas
--post-file sends the contents of file. Other than that, they work in
exactly the same way. In particular, they both expect content of the
form "key1=value1&key2=value2", with percent-encoding for special
characters; the only difference is that one expects its content as a
command-line parameter and the other accepts its content from a file. In
particular, --post-file is not for transmitting files as form
attachments: those must appear as "key=value" data (with appropriate
percent-coding) just like everything else. Wget does not currently
support "multipart/form-data" for transmitting POST data; only
"application/x-www-form-urlencoded". Only one of --post-data and
--post-file should be specified.
Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.
Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN
.
wget --post-data 'user=foo&password=bar' http://example.com/auth.php
Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.
I've discovered that you can use eval to avoid using a subshell. Thus:
IFS=$'\n' eval 'echo "${my_array[*]}"'
I found below SSH commands are robust for export/import huge MySql databases, at least I'm using them for years. Never rely on backups generated via control panels like cPanel WHM, CWP, OVIPanel, etc they may trouble you especially when you're switching between control panels, trust SSH always.
[EXPORT]
$ mysqldump -u root -p example_database| gzip > example_database.sql.gz
[IMPORT]
$ gunzip < example_database.sql.gz | mysql -u root -p example_database
Try setting 'clientCredentialType' to 'Windows' instead of 'Ntlm'.
I think that this is what the server is expecting - i.e. when it says the server expects "Negotiate,NTLM", that actually means Windows Auth, where it will try to use Kerberos if available, or fall back to NTLM if not (hence the 'negotiate')
I'm basing this on somewhat reading between the lines of: Selecting a Credential Type
Yes, here is an example in jsfiddle: http://jsfiddle.net/bfQeJ/
Highcharts.setOptions({
colors: ['#058DC7', '#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4']
});
The example is a pie chart but you can just fill the series with all the colors to your heart's content =)

I had the same problem, even after following Sinhue's setup, but I solved it.
The problem was that that something (Tomcat?) was forwarding from "/" to "/index.jsp" when I had the file index.jsp in my WebContent directory. When I removed that, the request did not get forwarded anymore.
What I did to diagnose the problem was to make a catch-all request handler and printed the servlet path to the console. This showed me that even though the request I was making was for http://localhost/myapp/, the servlet path was being changed to "/index.html". I was expecting it to be "/".
@RequestMapping("*")
public String hello(HttpServletRequest request) {
System.out.println(request.getServletPath());
return "hello";
}
So in summary, the steps you need to follow are:
<url-pattern>/</url-pattern>
RequestMapping("/")
Hope this helps.
You mus use nvarchar text too. that's mean you have to simply had a "N" before your massive string and that's it! no limitation anymore
DELARE @SQL NVARCHAR(MAX);
SET @SQL = N'SomeMassiveString > 4000 chars...';
EXEC(@SQL);

Why not using Cakes Response Class? You can set the status code of the response simply by this:
$this->response->statusCode(200);
Then just render a file with the error message, which suits best with JSON.
You may also need the following directive to be set before the first "sub_filter" for backend-servers with data compression:
proxy_set_header Accept-Encoding "";
Otherwise it may not work. For your example it will look like:
location /admin/ {
proxy_pass http://localhost:8080/;
proxy_set_header Accept-Encoding "";
sub_filter "http://your_server/" "http://your_server/admin/";
sub_filter_once off;
}
is this what you want?
var grouped = CustomerList.GroupBy(m => m.GroupID).Select((n) => new { GroupId = n.Key, Items = n.ToList() });
-(void) viewWillAppear:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}
mongodump --host test.mongodb.net --port 27017 --db --username --password --authenticationDatabase admin --ssl --out
mongorestore --db --verbose
Just to provide an another way, you can also simply use the following command
$ cat to_remove
/tmp/file1
/tmp/file2
/tmp/file3
$ rm $( cat to_remove )
I couldn't get GetAccessControl() to throw an exception on Windows 7 as recommended in the accepted answer.
I ended up using a variation of sdds's answer:
try
{
bool writeable = false;
WindowsPrincipal principal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
DirectorySecurity security = Directory.GetAccessControl(pstrPath);
AuthorizationRuleCollection authRules = security.GetAccessRules(true, true, typeof(SecurityIdentifier));
foreach (FileSystemAccessRule accessRule in authRules)
{
if (principal.IsInRole(accessRule.IdentityReference as SecurityIdentifier))
{
if ((FileSystemRights.WriteData & accessRule.FileSystemRights) == FileSystemRights.WriteData)
{
if (accessRule.AccessControlType == AccessControlType.Allow)
{
writeable = true;
}
else if (accessRule.AccessControlType == AccessControlType.Deny)
{
//Deny usually overrides any Allow
return false;
}
}
}
}
return writeable;
}
catch (UnauthorizedAccessException)
{
return false;
}
Hope this helps.

In postgresql you can use regular expressions in WHERE clause. Check http://www.postgresql.org/docs/8.4/static/functions-matching.html
MySQL has something simmilar: http://dev.mysql.com/doc/refman/5.5/en/regexp.html
This worked for me:

Starting with AspNetCore 2.0, it's recommended to use ContentResult
instead of the Produce
attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885
This doesn't rely on serialization nor on content negotiation.
[HttpGet]
public ContentResult Index() {
return new ContentResult {
ContentType = "text/html",
StatusCode = (int)HttpStatusCode.OK,
Content = "<html><body>Hello World</body></html>"
};
}
If you want a const string that contains Environment.NewLine in it you can do something like this:
const string stringWithNewLine =
@"first line
second line
third line";
Since this is in a const string it is done in compile time therefore it is the compiler's interpretation of a newline. I can't seem to find a reference explaining this behavior but, I can prove it works as intended. I compiled this code on both Windows and Ubuntu (with Mono) then disassembled and these are the results:
As you can see, in Windows newlines are interpreted as \r\n and on Ubuntu as \n

This example will show two methods to programmatically add the following constraints the same as if doing it in the Interface Builder:
Width and Height
Center in Container
override func viewDidLoad() {
super.viewDidLoad()
// set up the view
let myView = UIView()
myView.backgroundColor = UIColor.blue
myView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(myView)
// Add constraints code here (choose one of the methods below)
// ...
}
// width and height
myView.widthAnchor.constraint(equalToConstant: 200).isActive = true
myView.heightAnchor.constraint(equalToConstant: 100).isActive = true
// center in container
myView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
myView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
// width and height
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.width, relatedBy: NSLayoutRelation.equal, toItem: nil, attribute: NSLayoutAttribute.notAnAttribute, multiplier: 1, constant: 200).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.height, relatedBy: NSLayoutRelation.equal, toItem: nil, attribute: NSLayoutAttribute.notAnAttribute, multiplier: 1, constant: 100).isActive = true
// center in container
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.centerX, relatedBy: NSLayoutRelation.equal, toItem: view, attribute: NSLayoutAttribute.centerX, multiplier: 1, constant: 0).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.centerY, relatedBy: NSLayoutRelation.equal, toItem: view, attribute: NSLayoutAttribute.centerY, multiplier: 1, constant: 0).isActive = true

For anyone else that comes across this post and might find it useful... There is actually nothing wrong with my code. I made the mistake of requesting client_credentials type access code instead of password access code (#facepalms). FYI I am using urlencoded post hence the use of querystring.. So for those that may be looking for some example code.. here is my full request
Big thanks to @swapnil for trying to help me debug this.
const data = {
grant_type: USER_GRANT_TYPE,
client_id: CLIENT_ID,
client_secret: CLIENT_SECRET,
scope: SCOPE_INT,
username: DEMO_EMAIL,
password: DEMO_PASSWORD
};
axios.post(TOKEN_URL, Querystring.stringify(data))
.then(response => {
console.log(response.data);
USER_TOKEN = response.data.access_token;
console.log('userresponse ' + response.data.access_token);
})
.catch((error) => {
console.log('error ' + error);
});
const AuthStr = 'Bearer '.concat(USER_TOKEN);
axios.get(URL, { headers: { Authorization: AuthStr } })
.then(response => {
// If request is good...
console.log(response.data);
})
.catch((error) => {
console.log('error ' + error);
});
The variable name you're looking for is ansible_ssh_private_key_file
.
You should set it at 'vars' level:
in the inventory file:
myHost ansible_ssh_private_key_file=~/.ssh/mykey1.pem
myOtherHost ansible_ssh_private_key_file=~/.ssh/mykey2.pem
in the host_vars
:
# hosts_vars/myHost.yml
ansible_ssh_private_key_file: ~/.ssh/mykey1.pem
# hosts_vars/myOtherHost.yml
ansible_ssh_private_key_file: ~/.ssh/mykey2.pem
in a group_vars
file if you use the same key for a group of hosts
in the vars
section of your play:
- hosts: myHost
remote_user: ubuntu
vars_files:
- vars.yml
vars:
ansible_ssh_private_key_file: "{{ key1 }}"
tasks:
- name: Echo a hello message
command: echo hello

Set up a simple repository using a web server with its default configuration. The key is the directory structure. The documentation does not mention it explicitly, but it is the same structure as a local repository.
To set up an internal repository just requires that you have a place to put it, and then start copying required artifacts there using the same layout as in a remote repository such as repo.maven.apache.org. Source
Add a file to your repository like this:
mvn install:install-file \
-Dfile=YOUR_JAR.jar -DgroupId=YOUR_GROUP_ID
-DartifactId=YOUR_ARTIFACT_ID -Dversion=YOUR_VERSION \
-Dpackaging=jar \
-DlocalRepositoryPath=/var/www/html/mavenRepository
If your domain is example.com
and the root directory of the web server is located at /var/www/html/
, then maven can find "YOUR_JAR.jar" if configured with <url>http://example.com/mavenRepository</url>
.

If you're writing GPLed code and using GNU autotools, then a portable way that takes care of the details on many OSes (including Windows and macOS) is gnulib's relocatable-prog
module.
The BigDecimal(double) constructor can have unpredictable behaviors. It is preferable to use BigDecimal(String) or BigDecimal.valueOf(double).
System.out.println(new BigDecimal(135.69)); //135.68999999999999772626324556767940521240234375
System.out.println(new BigDecimal("135.69")); // 135.69
System.out.println(BigDecimal.valueOf(135.69)); // 135.69
The documentation for BigDecimal(double) explains in detail:
- The results of this constructor can be somewhat unpredictable. One might assume that writing new BigDecimal(0.1) in Java creates a BigDecimal which is exactly equal to 0.1 (an unscaled value of 1, with a scale of 1), but it is actually equal to 0.1000000000000000055511151231257827021181583404541015625. This is because 0.1 cannot be represented exactly as a double (or, for that matter, as a binary fraction of any finite length). Thus, the value that is being passed in to the constructor is not exactly equal to 0.1, appearances notwithstanding.
- The String constructor, on the other hand, is perfectly predictable: writing new BigDecimal("0.1") creates a BigDecimal which is exactly equal to 0.1, as one would expect. Therefore, it is generally recommended that the String constructor be used in preference to this one.
- When a double must be used as a source for a BigDecimal, note that this constructor provides an exact conversion; it does not give the same result as converting the double to a String using the Double.toString(double) method and then using the BigDecimal(String) constructor. To get that result, use the static valueOf(double) method.
Events in modern DOM implementations have two phases, capturing and bubbling. The capturing phase is the first phase, flowing from the defaultView
of the document to the event target, followed by the bubbling phase, flowing from the event target back to the defaultView
. For more information, see http://www.w3.org/TR/DOM-Level-3-Events/#event-flow.
To handle the capturing phase of an event, you need to set the third argument for addEventListener
to true
:
document.body.addEventListener('click', fn, true);
Sadly, as Wesley mentioned, the capturing phase of an event cannot be handled reliably, or at all, in older browsers.
One possible solution is to handle the mouseup
event instead, since event order for clicks is:
If you can be sure you have no handlers cancelling the mouseup
event, then this is one way (and, arguably, a better way) to go. Another thing to note is that many, if not most (if not all), UI menus disappear on mouse down.
This answer is similar to @PaulMcG's answer but doesn't require sorting the input.
For those into functional programming, groupBy
can be written in one line (not including imports!), and unlike itertools.groupby
it doesn't require the input to be sorted:
from functools import reduce # import needed for python3; builtin in python2
from collections import defaultdict
def groupBy(key, seq):
return reduce(lambda grp, val: grp[key(val)].append(val) or grp, seq, defaultdict(list))
(The reason for ... or grp
in the lambda
is that for this reduce()
to work, the lambda
needs to return its first argument; because list.append()
always returns None
the or
will always return grp
. I.e. it's a hack to get around python's restriction that a lambda can only evaluate a single expression.)
This returns a dict whose keys are found by evaluating the given function and whose values are a list of the original items in the original order. For the OP's example, calling this as groupBy(lambda pair: pair[1], input)
will return this dict:
{'KAT': [('11013331', 'KAT'), ('9843236', 'KAT')],
'NOT': [('9085267', 'NOT'), ('11788544', 'NOT')],
'ETH': [('5238761', 'ETH'), ('5349618', 'ETH'), ('962142', 'ETH'), ('7795297', 'ETH'), ('7341464', 'ETH'), ('5594916', 'ETH'), ('1550003', 'ETH')]}
And as per @PaulMcG's answer the OP's requested format can be found by wrapping that in a list comprehension. So this will do it:
result = {key: [pair[0] for pair in values],
for key, values in groupBy(lambda pair: pair[1], input).items()}
For Non String list
we can do like this as well
" ".join(map(str, my_list))
For anyone learning this stuff, comments are more important, so drawing on Xak Tacit's idea

xmlns:ØignoreØ="http://www.galasoft.ch/ignore"
mc:Ignorable="ØignoreØ"

You have your arguments to the remote add

git remote add <NAME> <PATH>
So:
git remote add bak /home/sas/dev/apps/smx/repo/bak/ontologybackend/.git
See git remote --help
for more information.
I've made a short code to do that and I want to share it with you.
Here the main code:
public void Send(string from, string password, string to, string Message, string subject, string host, int port, string file)
{
MailMessage email = new MailMessage();
email.From = new MailAddress(from);
email.To.Add(to);
email.Subject = subject;
email.Body = Message;
SmtpClient smtp = new SmtpClient(host, port);
smtp.UseDefaultCredentials = false;
NetworkCredential nc = new NetworkCredential(from, password);
smtp.Credentials = nc;
smtp.EnableSsl = true;
email.IsBodyHtml = true;
email.Priority = MailPriority.Normal;
email.BodyEncoding = Encoding.UTF8;
if (file.Length > 0)
{
Attachment attachment;
attachment = new Attachment(file);
email.Attachments.Add(attachment);
}
// smtp.Send(email);
smtp.SendCompleted += new SendCompletedEventHandler(SendCompletedCallBack);
string userstate = "sending ...";
smtp.SendAsync(email, userstate);
}
private static void SendCompletedCallBack(object sender,AsyncCompletedEventArgs e) {
string result = "";
if (e.Cancelled)
{
MessageBox.Show(string.Format("{0} send canceled.", e.UserState),"Message",MessageBoxButtons.OK,MessageBoxIcon.Information);
}
else if (e.Error != null)
{
MessageBox.Show(string.Format("{0} {1}", e.UserState, e.Error), "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else {
MessageBox.Show("your message is sended", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
In your button do stuff like this
you can add your jpg or pdf files and more .. this is just an example
using (OpenFileDialog attachement = new OpenFileDialog()
{
Filter = "Exel Client|*.png",
ValidateNames = true
})
{
if (attachement.ShowDialog() == DialogResult.OK)
{
Send("[email protected]", "gmail_password",
"[email protected]", "just smile ", "mail with attachement",
"smtp.gmail.com", 587, attachement.FileName);
}
}

Tensorflow 2.0

If you get an error, you need to check your installation.
I would recommend %20
.
Are you hard-coding them?
This is not very consistent across languages, though.
If I'm not mistaken, in PHP urlencode()
treats spaces as +
whereas Python's urlencode()
treats them as %20
.
EDIT:
It seems I'm mistaken. Python's urlencode()
(at least in 2.7.2) uses quote_plus()
instead of quote()
and thus encodes spaces as "+".
It seems also that the W3C recommendation is the "+" as per here: http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1
And in fact, you can follow this interesting debate on Python's own issue tracker about what to use to encode spaces: http://bugs.python.org/issue13866.
EDIT #2:
I understand that the most common way of encoding " " is as "+", but just a note, it may be just me, but I find this a bit confusing:
import urllib
print(urllib.urlencode({' ' : '+ '})
>>> '+=%2B+'
There is no conversion between InputStream/OutputStream and the bytes they are working with. They are made for binary data, and just read (or write) the bytes one by one as is.
A conversion needs to happen when you want to go from byte to char. Then you need to convert using a character set. This happens when you make String or Reader from bytes, which are made for character data.
This previous question mentions using qSleep()
which is in the QtTest
module. To avoid the overhead linking in the QtTest
module, looking at the source for that function you could just make your own copy and call it. It uses defines to call either Windows Sleep()
or Linux nanosleep()
.
#ifdef Q_OS_WIN
#include <windows.h> // for Sleep
#endif
void QTest::qSleep(int ms)
{
QTEST_ASSERT(ms > 0);
#ifdef Q_OS_WIN
Sleep(uint(ms));
#else
struct timespec ts = { ms / 1000, (ms % 1000) * 1000 * 1000 };
nanosleep(&ts, NULL);
#endif
}
each
passes into your function index
and element
. Check index
against the length of the set and you're good to go:
var set = $('.requiredText');
var length = set.length;
set.each(function(index, element) {
thisVal = $(this).val();
if(parseInt(thisVal) !== 0) {
console.log('Valid Field: ' + thisVal);
if (index === (length - 1)) {
console.log('Last field, submit form here');
}
}
});
I did it with observer mode.
Observer interface
public interface Observer {
public void update(Subject subject);
}
Base Subject
public class Subject {
private List<Observer> observers = new ArrayList<Observer>();
public void attach(Observer observer){
observers.add(observer);
}
public void detach(Observer observer){
observers.remove(observer);
}
protected void notifyObservers(){
for(Observer observer : observers){
observer.update(this);
}
}
}
Child Subject implements the exit method
public class ApplicationSubject extends Subject {
public void exit(){
notifyObservers();
}
}
MyApplication which your application should extends it
public class MyApplication extends Application {
private static ApplicationSubject applicationSubject;
public ApplicationSubject getApplicationSubject() {
if(applicationSubject == null) applicationSubject = new ApplicationSubject();
return applicationSubject;
}
}
Base Activity
public abstract class BaseActivity extends Activity implements Observer {
public MyApplication app;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
app = (MyApplication) this.getApplication();
app.getApplicationSubject().attach(this);
}
@Override
public void finish() {
// TODO Auto-generated method stub
app.getApplicationSubject().detach(this);
super.finish();
}
/**
* exit the app
*/
public void close() {
app.getApplicationSubject().exit();
};
@Override
public void update(Subject subject) {
// TODO Auto-generated method stub
this.finish();
}
}
let's test it
public class ATestActivity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
close(); //invoke 'close'
}
}
In the plyr
package there is a function rbind.fill
that will merge data.frames and introduce NA
for empty cells:
library(plyr)
combined <- rbind.fill(mtcars[c("mpg", "wt")], mtcars[c("wt", "cyl")])
combined[25:40, ]
mpg wt cyl

33 NA 2.620 6
34 NA 2.875 6
35 NA 2.320 4
Please consider replacring the accepted solution with the following:
parse_url() will always include any sub-domain(s), so this function doesn't parse domain names very well. Here are some examples:
$url = 'http://www.google.com/dhasjkdas/sadsdds/sdda/sdads.html';
$parse = parse_url($url);
echo $parse['host']; // prints 'www.google.com'
echo parse_url('https://subdomain.example.com/foo/bar', PHP_URL_HOST);
// Output: subdomain.example.com
echo parse_url('https://subdomain.example.co.uk/foo/bar', PHP_URL_HOST);
// Output: subdomain.example.co.uk
Instead, you may consider this pragmatic solution. It will cover many, but not all domain names -- for instance, lower-level domains such as 'sos.state.oh.us' are not covered.
function getDomain($url) {
$host = parse_url($url, PHP_URL_HOST);
if(filter_var($host,FILTER_VALIDATE_IP)) {
// IP address returned as domain
return $host; //* or replace with null if you don't want an IP back
}
$domain_array = explode(".", str_replace('www.', '', $host));
$count = count($domain_array);
if( $count>=3 && strlen($domain_array[$count-2])==2 ) {
// SLD (example.co.uk)
return implode('.', array_splice($domain_array, $count-3,3));
} else if( $count>=2 ) {
// TLD (example.com)
return implode('.', array_splice($domain_array, $count-2,2));
}
}
// Your domains
echo getDomain('http://google.com/dhasjkdas/sadsdds/sdda/sdads.html'); // google.com
echo getDomain('http://www.google.com/dhasjkdas/sadsdds/sdda/sdads.html'); // google.com
echo getDomain('http://google.co.uk/dhasjkdas/sadsdds/sdda/sdads.html'); // google.co.uk
// TLD
echo getDomain('https://shop.example.com'); // example.com
echo getDomain('https://foo.bar.example.com'); // example.com
echo getDomain('https://www.example.com'); // example.com
echo getDomain('https://example.com'); // example.com
// SLD
echo getDomain('https://more.news.bbc.co.uk'); // bbc.co.uk
echo getDomain('https://www.bbc.co.uk'); // bbc.co.uk
echo getDomain('https://bbc.co.uk'); // bbc.co.uk
// IP
echo getDomain('https://1.2.3.45'); // 1.2.3.45
Finally, Jeremy Kendall's PHP Domain Parser allows you to parse the domain name from a url. League URI Hostname Parser will also do the job.

I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

I had a related issue working within Spyder, but the problem seems to be the relationship between the escape character ( "\") and the "\" in the path name Here's my illustration and solution (note single \ vs double \\ ):
path = 'C:\Users\myUserName\project\subfolder'
path # 'C:\\Users\\myUserName\\project\subfolder'
os.listdir(path) # gives windows error
path = 'C:\\Users\\myUserName\\project\\subfolder'
os.listdir(path) # gives expected behavior
I tested all the cases in the latest Chrome, Firefox, Safari in 2019.
Response to Added:
Yes:
>>> from collections import Counter
>>> x = Counter({'a':5, 'b':3, 'c':7})
Using the sorted keyword key and a lambda function:
>>> sorted(x.items(), key=lambda i: i[1])
[('b', 3), ('a', 5), ('c', 7)]
>>> sorted(x.items(), key=lambda i: i[1], reverse=True)
[('c', 7), ('a', 5), ('b', 3)]
This works for all dictionaries. However Counter
has a special function which already gives you the sorted items (from most frequent, to least frequent). It's called most_common()
:
>>> x.most_common()
[('c', 7), ('a', 5), ('b', 3)]
>>> list(reversed(x.most_common())) # in order of least to most
[('b', 3), ('a', 5), ('c', 7)]
You can also specify how many items you want to see:
>>> x.most_common(2) # specify number you want
[('c', 7), ('a', 5)]
There is a free and open-source GUI tool KeyStore Explorer to work with crypto key containers. Using it you can export a certificate or private key into separate files or convert the container into another format (jks, pem, p12, pkcs12, etc)
Do you see anything wrong with the code?
Yes. Why are you adding the three fields together before you compare them?
I would probably do something like this: (assuming the fields are in the order you wish to sort them in)
@Override public int compare(final Report record1, final Report record2) {
int c;
c = record1.getReportKey().compareTo(record2.getReportKey());
if (c == 0)
c = record1.getStudentNumber().compareTo(record2.getStudentNumber());
if (c == 0)
c = record1.getSchool().compareTo(record2.getSchool());
return c;
}
based on the some of above replies i improvised it a bit
create this method and call it by passing your resource
Reusable Method
public String getURLForResource (int resourceId) {
//use BuildConfig.APPLICATION_ID instead of R.class.getPackage().getName() if both are not same
return Uri.parse("android.resource://"+R.class.getPackage().getName()+"/" +resourceId).toString();
}
Sample call
getURLForResource(R.drawable.personIcon)
complete example of loading image
String imageUrl = getURLForResource(R.drawable.personIcon);
// Load image
Glide.with(patientProfileImageView.getContext())
.load(imageUrl)
.into(patientProfileImageView);
you can move the function getURLForResource to a Util file and make it static so it can be reused
Or - build on @Jamaica Geek's answer, using Express - to avoid saving and reading a file:
res.attachment('file.xls');
var header="Sl No"+"\t"+" Age"+"\t"+"Name"+"\n";
var row1 = [0,21,'BOB'].join('\t')
var row2 = [0,22,'bob'].join('\t');
var c = header + row1 + row2;
return res.send(c);
Something like this:
Dim rng As Range
Dim row As Range
Dim cell As Range
Set rng = Range("A1:C2")
For Each row In rng.Rows
For Each cell in row.Cells
'Do Something
Next cell
Next row
I used the FORMAT function to accomplish this:
select
FORMAT(Closing_Date, 'yyyy_MM') AS Closing_Month
, count(*) cc
FROM
MyTable
WHERE
Defect_Status1 IS NOT NULL
AND Closing_Date >= '2011-12-01'
AND Closing_Date < '2016-07-01'
GROUP BY FORMAT(Closing_Date, 'yyyy_MM')
ORDER BY Closing_Month
text-shadow:
1px 1px 2px black,
1px -1px 2px black,
-1px 1px 2px black,
-1px -1px 2px black;
Consider using NumberFormatter for this purpose, it provides more flexibility if you want to print the percentage sign of the ratio or if you have things like currency and large numbers.
let amount = 10.000001
let formatter = NumberFormatter()
formatter.numberStyle = .decimal
formatter.maximumFractionDigits = 2
let formattedAmount = formatter.string(from: amount as NSNumber)!
print(formattedAmount) // 10
Try:
<input type="submit" style="position: absolute; left: -9999px"/>
That will push the button waaay to the left, out of the screen. The nice thing with this is, you'd get graceful degradation when CSS is disabled.
Update - Workaround for IE7
As suggested by Bryan Downing + with tabindex
to prevent tab reach this button (by Ates Goral):
<input type="submit"
style="position: absolute; left: -9999px; width: 1px; height: 1px;"
tabindex="-1" />
If you're sane about it, editing the config file's safe enough. If you want to be a little more paranoid, you can use the porcelain command to modify it:
git config branch.master.remote newserver
Of course, if you look at the config before and after, you'll see that it did exactly what you were going to do.
But in your individual case, what I'd do is:
git remote rename origin old-origin
git remote rename new-origin origin
That is, if the new server is going to be the canonical remote, why not call it origin as if you'd originally cloned from it?
new Date().toISOString()
"2016-02-18T23:59:48.039Z"
new Date().toISOString().split('T')[0];
"2016-02-18"
new Date().toISOString().replace('-', '/').split('T')[0].replace('-', '/');
"2016/02/18"
new Date().toLocaleString().split(',')[0]
"2/18/2016"
You can actually write to a named pipe using its name, btw.
Open a command shell as Administrator to get around the default "Access is denied" error:
echo Hello > \\.\pipe\PipeName
I have solved this issue by below steps:
Now you can see below in all type of Explorers (Package or Project or Navigator)

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.
The relevant paragraph:
Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.
This makes lots of sense.
For your specific question.. the o
in the <o:p>
means "Office namespace" so anything following the o:
in a tag means "I'm part of Office namespace" - in case of <o:p>
it just means paragraph, the equivalent of the ordinary <p>
tag.
I assume that every HTML tag has its Office "equivalent" and they have more.
If you are using post as a model (without dependency injection), you can also do:
$posts = Post::orderBy('id', 'DESC')->get();
DECLARE @i AS FLOAT = 2 SELECT @i / 3 SELECT cast(@i / cast(3 AS DECIMAL(18,2))as decimal (18,2))
Both factor and result requires casting to be considered as decimals.
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 $watches()
that Angular 1 would set up for {{}}
template bindings.onPush
change detection strategy on any of your components), every component in the tree is examined once (TTL=1)... from the top, in depth-first order. (Well, if you're in dev mode, change detection runs twice (TTL=2). See ApplicationRef.tick() for more about this.) It performs dirty checking on all of your bindings, using those change detector objects.
ngOnChanges()
to be notified of changes. ngDoCheck()
(see this SO answer for more on this). Other references to learn more:
onPush
.Walking through a directory tree is a good example. You can do something similar to process an array. Here is a really simple recursive function that simply processes a string, a simple array of strings, or a nested array of strings of any depth, replacing instances of 'hello' with 'goodbye' in the string or the values of the array or any sub-array:
function replaceHello($a) {
if (! is_array($a)) {
$a = str_replace('hello', 'goodbye', $a);
} else {
foreach($a as $key => $value) {
$a[$key] = replaceHello($value);
}
}
return $a
}
It knows when to quit because at some point, the "thing" it is processing is not an array. For example, if you call replaceHello('hello'), it will return 'goodbye'. If you send it an array of strings, though it will call itself once for every member of the array, then return the processed array.
Assign the window.onerror
event to an event handler like:
<script type="text/javascript">
window.onerror = function(msg, url, line, col, error) {
// Note that col & error are new to the HTML 5 spec and may not be
// supported in every browser. It worked for me in Chrome.
var extra = !col ? '' : '\ncolumn: ' + col;
extra += !error ? '' : '\nerror: ' + error;
// You can view the information in an alert to see things working like this:
alert("Error: " + msg + "\nurl: " + url + "\nline: " + line + extra);
// TODO: Report this error via ajax so you can keep track
// of what pages have JS issues
var suppressErrorAlert = true;
// If you return true, then error alerts (like in older versions of
// Internet Explorer) will be suppressed.
return suppressErrorAlert;
};
</script>
As commented in the code, if the return value of window.onerror
is true
then the browser should suppress showing an alert dialog.
In a nutshell, the event is raised when either 1.) there is an uncaught exception or 2.) a compile time error occurs.
uncaught exceptions
- throw "some messages"
- call_something_undefined();
- cross_origin_iframe.contentWindow.document;, a security exception
compile error
<script>{</script>
<script>for(;)</script>
<script>"oops</script>
setTimeout("{", 10);
, it will attempt to compile the first argument as a script
Example of the onerror code above in action after adding this to a test page:
<script type="text/javascript">
call_something_undefined();
</script>
var error_data = {
url: document.location.href,
};
if(error != null) {
error_data['name'] = error.name; // e.g. ReferenceError
error_data['message'] = error.line;
error_data['stack'] = error.stack;
} else {
error_data['msg'] = msg;
error_data['filename'] = filename;
error_data['line'] = line;
error_data['col'] = col;
}
var xhr = new XMLHttpRequest();
xhr.open('POST', '/ajax/log_javascript_error');
xhr.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.onload = function() {
if (xhr.status === 200) {
console.log('JS error logged');
} else if (xhr.status !== 200) {
console.error('Failed to log JS error.');
console.error(xhr);
console.error(xhr.status);
console.error(xhr.responseText);
}
};
xhr.send(JSON.stringify(error_data));

It happens because of not very straight forward Servlet specification. If you are working with a native HttpServletRequest
implementation you cannot get both the URL encode body and the parameters. Spring does some workarounds, which make it even more strange and nontransparent.
In such cases Spring (version 3.2.4) re-renders a body for you using data from the getParameterMap()
method. It mixes GET and POST parameters and breaks the parameter order. The class, which is responsible for the chaos is ServletServerHttpRequest
. Unfortunately it cannot be replaced, but the class StringHttpMessageConverter
can be.
The clean solution is unfortunately not simple:
StringHttpMessageConverter
. Copy/Overwrite the original class adjusting method readInternal()
.HttpServletRequest
overwriting getInputStream()
, getReader()
and getParameter*()
methods.In the method StringHttpMessageConverter#readInternal following code must be used:
if (inputMessage instanceof ServletServerHttpRequest) {
ServletServerHttpRequest oo = (ServletServerHttpRequest)inputMessage;
input = oo.getServletRequest().getInputStream();
} else {
input = inputMessage.getBody();
}
Then the converter must be registered in the context.
<mvc:annotation-driven>
<mvc:message-converters register-defaults="true/false">
<bean class="my-new-converter-class"/>
</mvc:message-converters>
</mvc:annotation-driven>
The step two is described here: Http Servlet request lose params from POST body after read it once
The problem is that if you try to write a <table>
or a <tr>
or <td>
tag using JS every time you insert a new tag the browser will try to close it as it will think that there is an error on the code.
Instead of writing your table line by line, concatenate your table into a variable and insert it once created:
<script language="javascript" type="text/javascript">
<!--
var myArray = new Array();
myArray[0] = 1;
myArray[1] = 2.218;
myArray[2] = 33;
myArray[3] = 114.94;
myArray[4] = 5;
myArray[5] = 33;
myArray[6] = 114.980;
myArray[7] = 5;
var myTable= "<table><tr><td style='width: 100px; color: red;'>Col Head 1</td>";
myTable+= "<td style='width: 100px; color: red; text-align: right;'>Col Head 2</td>";
myTable+="<td style='width: 100px; color: red; text-align: right;'>Col Head 3</td></tr>";
myTable+="<tr><td style='width: 100px; '>---------------</td>";
myTable+="<td style='width: 100px; text-align: right;'>---------------</td>";
myTable+="<td style='width: 100px; text-align: right;'>---------------</td></tr>";
for (var i=0; i<8; i++) {
myTable+="<tr><td style='width: 100px;'>Number " + i + " is:</td>";
myArray[i] = myArray[i].toFixed(3);
myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td>";
myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td></tr>";
}
myTable+="</table>";
document.write( myTable);
//-->
</script>
If your code is in an external JS file, in HTML create an element with an ID where you want your table to appear:
<div id="tablePrint"> </div>
And in JS instead of document.write(myTable)
use the following code:
document.getElementById('tablePrint').innerHTML = myTable;
You have to first declare delegate's type because delegates are strongly typed:
public void MyCallbackDelegate( string str );
public void DoRequest(string request, MyCallbackDelegate callback)
{
// do stuff....
callback("asdf");
}
