As Blexy already answered, go to "Behavior > Site Content > All Pages".
Just pay attention that "Behavior" appears two times in the left sidebar and we need to click on the second option:
Another solution is to set the 'onclick' attribute to a function that returns your writeLED function.
document.getElementById('buttonLED'+id).onclick = function(){ return writeLED(1,1)};
This can also be useful for other cases when you create an element in JavaScript while it has not yet been drawn in the browser.
The primary difference between the two is the following

Why fight it? Why not simply control your table width using the bootstrap grid?
<div class="row">
<div class="col-sm-6">
<table></table>
</div>
</div>
This will create a table that is half (6 out of 12) of the width of the containing element.
I sometimes use inline styles as per the other answers, but it is discouraged.
Bootstrap 4 has some nice helper classes for width like w-25
, w-50
, w-75
, w-100
, and w-auto
. This will make the table 50% width:
<table class="w-50"></table>
Here's the doc: https://getbootstrap.com/docs/4.0/utilities/sizing/
DECLARE @x int=1
declare @exit bit=1
WHILE @x<=len('123c') AND @exit=1
BEGIN
IF ascii(SUBSTRING('123c',@x,1)) BETWEEN 48 AND 57
BEGIN
set @x=@x+1
END
ELSE
BEGIN
SET @exit=0
PRINT 'string is not all numeric -:('
END
END
There are two main differences.
The first one is related to how you will access the relationship. For a unidirectional association, you can navigate the association from one end only.
So, for a unidirectional @ManyToOne
association, it means you can only access the relationship from the child side where the foreign key resides.
If you have a unidirectional @OneToMany
association, it means you can only access the relationship from the parent side which manages the foreign key.
For the bidirectional @OneToMany
association, you can navigate the association in both ways, either from the parent or from the child side.
You also need to use add/remove utility methods for bidirectional associations to make sure that both sides are properly synchronized.
The second aspect is related to performance.
@OneToMany
, unidirectional associations don't perform as well as bidirectional ones.@OneToOne
, a bidirectional association will cause the parent to be fetched eagerly if Hibernate cannot tell whether the Proxy should be assigned or a null value.@ManyToMany
, the collection type makes quite a difference as Sets
perform better than Lists
.I faced the same problem in eclipse with tomcat7 with the error javax.servlet cannot be resolved. If I select the server in targeted runtime mode and build project again, the error get's resolved.
To get public static void main(String[] args) line in eclipse without typing the whole line type "main" and press Ctrl + space then, you will get the option for the main method select it.
If fptr
is NULL
, then you don't have an open file. Therefore, you can't freopen
it, you should just fopen
it.
FILE *fptr;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
fptr = fopen("scores.dat", "wb");
}
note: Since the behavior of your program varies depending on whether the file is opened in read or write modes, you most probably also need to keep a variable indicating which is the case.
int main()
{
FILE *fptr;
char there_was_error = 0;
char opened_in_read = 1;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
opened_in_read = 0;
fptr = fopen("scores.dat", "wb");
if (fptr == NULL)
there_was_error = 1;
}
if (there_was_error)
{
printf("Disc full or no permission\n");
return EXIT_FAILURE;
}
if (opened_in_read)
printf("The file is opened in read mode."
" Let's read some cached data\n");
else
printf("The file is opened in write mode."
" Let's do some processing and cache the results\n");
return EXIT_SUCCESS;
}
If you are using 'request.js' you might use the following:
var options = {
url: 'localhost',
method: 'GET',
headers:{
Accept: '*/*'
}
}
request(options, function (error, response, body) {
...
})
var rowHandle = gridView.FocusedRowHandle;
var obj = gridView.GetRowCellValue(rowHandle, "FieldName");
//For example
int val= Convert.ToInt32(gridView.GetRowCellValue(rowHandle, "FieldName"));
You can also use a helper function to add spacing after each child.
List<Widget> childrenWithSpacing({
@required List<Widget> children,
double spacing = 8,
}) {
final space = Container(width: spacing, height: spacing);
return children.expand((widget) => [widget, space]).toList();
}
So then, the returned list may be used as a children of a column
Column(
children: childrenWithSpacing(
spacing: 14,
children: [
Text('This becomes a text with an adjacent spacing'),
if (true == true) Text('Also, makes it easy to add conditional widgets'),
],
),
);
I'm not sure though if it's wrong or have a performance penalty to run the children through a helper function for the same goal?
Your Mileage May Vary, I attempted @senderle's spin on Vartec's solution in Windows on Python 2.6.5, but I was getting errors, and no other solutions worked. My error was: WindowsError: [Error 6] The handle is invalid
.
I found that I had to assign PIPE to every handle to get it to return the output I expected - the following worked for me.
import subprocess
def run_command(cmd):
"""given shell command, returns communication tuple of stdout and stderr"""
return subprocess.Popen(cmd,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE,
stdin=subprocess.PIPE).communicate()
and call like this, ([0]
gets the first element of the tuple, stdout
):
run_command('tracert 11.1.0.1')[0]
After learning more, I believe I need these pipe arguments because I'm working on a custom system that uses different handles, so I had to directly control all the std's.
To stop console popups (with Windows), do this:
def run_command(cmd):
"""given shell command, returns communication tuple of stdout and stderr"""
# instantiate a startupinfo obj:
startupinfo = subprocess.STARTUPINFO()
# set the use show window flag, might make conditional on being in Windows:
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
# pass as the startupinfo keyword argument:
return subprocess.Popen(cmd,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE,
stdin=subprocess.PIPE,
startupinfo=startupinfo).communicate()
run_command('tracert 11.1.0.1')
For me (react-router v4, react v16) the problem was that I had the navigation component all right:
import { Link, withRouter } from 'react-router-dom'
class MainMenu extends Component {
render() {
return (
...
<NavLink to="/contact">Contact</NavLink>
...
);
}
}
export default withRouter(MainMenu);
Both using either
to="/contact"
or
OnClick={() => this.props.history.push('/contact')};
The behavior was still the same - the URL in browser changed but wrong components were rendered, the router was called with the same old URL.
The culprit was in the router definition. I had to move the MainMenu component as a child of the Router component!
// wrong placement of the component that calls the router
<MainMenu history={this.props.history} />
<Router>
<div>
// this is the right place for the component!
<MainMenu history={this.props.history} />
<Route path="/" exact component={MainPage} />
<Route path="/contact/" component={MainPage} />
</div>
</Router>
One easy step:
$ npm i -g npm-check-updates && ncu -u && npm i
That is all. All of the package versions in package.json
will be the latest major versions.
Edit:
What is happening here?
Installing a package that checks updates for you.
Use this package to update all package versions in your
package.json
(-u is short for --updateAll).Install all of the new versions of the packages.
I needed to explicitly add POST in the CURL command:
curl -X POST http://<user>:<token>@<server>/safeRestart
I also have the SafeRestart Plugin installed, in case that makes a difference.
What about the DATEDIFF function ?
Quoting the manual's page :
DATEDIFF() returns expr1 – expr2 expressed as a value in days from one date to the other. expr1 and expr2 are date or date-and-time expressions. Only the date parts of the values are used in the calculation
In your case, you'd use :
mysql> select datediff('2010-04-15', '2010-04-12');
+--------------------------------------+
| datediff('2010-04-15', '2010-04-12') |
+--------------------------------------+
| 3 |
+--------------------------------------+
1 row in set (0,00 sec)
But note the dates should be written as YYYY-MM-DD
, and not DD-MM-YYYY
like you posted.
If you set CURLOPT_RETURNTRANSFER
to true
or 1
then the return value from curl_exec
will be the actual result from the successful operation. In other words it will not return TRUE
on success. Although it will return FALSE
on failure.
As described in the Return Values section of curl-exec
PHP manual page: http://php.net/manual/function.curl-exec.php
You should enable the CURLOPT_FOLLOWLOCATION
option for redirects but this would be a problem if your server is in safe_mode
and/or open_basedir
is in effect which can cause issues with curl as well.
There are a lot of great answers here. While there are usually quick solutions to the problem, some of which feel more pythonic than others, if you have the luxury of doing some refactoring, another approach is to analyze the organization of your code, and try to remove the circular dependency. You may find, for example, that you have:
File a.py
from b import B
class A:
@staticmethod
def save_result(result):
print('save the result')
@staticmethod
def do_something_a_ish(param):
A.save_result(A.use_param_like_a_would(param))
@staticmethod
def do_something_related_to_b(param):
B.do_something_b_ish(param)
File b.py
from a import A
class B:
@staticmethod
def do_something_b_ish(param):
A.save_result(B.use_param_like_b_would(param))
In this case, just moving one static method to a separate file, say c.py
:
File c.py
def save_result(result):
print('save the result')
will allow removing the save_result
method from A, and thus allow removing the import of A from a in b:
Refactored File a.py
from b import B
from c import save_result
class A:
@staticmethod
def do_something_a_ish(param):
A.save_result(A.use_param_like_a_would(param))
@staticmethod
def do_something_related_to_b(param):
B.do_something_b_ish(param)
Refactored File b.py
from c import save_result
class B:
@staticmethod
def do_something_b_ish(param):
save_result(B.use_param_like_b_would(param))
In summary, if you have a tool (e.g. pylint or PyCharm) that reports on methods that can be static, just throwing a staticmethod
decorator on them might not be the best way to silence the warning. Even though the method seems related to the class, it might be better to separate it out, especially if you have several closely related modules that might need the same functionality and you intend to practice DRY principles.
As long as pip lives within the scripts folder you can run
python -m pip ....
This will tell python to get pip from inside the scripts folder. This is also a good way to have both python2.7 and pyhton3.5 on you computer and have them in different locations. I currently have both python2 and pyhton3 installed on windows. When I type python
it defaults to python2. But if I type python3
I can use python3. (I also had to change the python.exe file for python3 to "python3.exe")If I need to install flask for python 2 I can run
python -m pip install flask
and it will be installed in the pyhton2 folder, but if I need flask for python 3 I run:
python3 -m pip install flask
and I now have it in the python3 folder
public static string NumberToWords(int number)
{
if (number == 0)
return "zero";
if (number < 0)
return "minus " + NumberToWords(Math.Abs(number));
string words = "";
if ((number / 1000000) > 0)
{
words += NumberToWords(number / 1000000) + " million ";
number %= 1000000;
}
if ((number / 1000) > 0)
{
words += NumberToWords(number / 1000) + " thousand ";
number %= 1000;
}
if ((number / 100) > 0)
{
words += NumberToWords(number / 100) + " hundred ";
number %= 100;
}
if (number > 0)
{
if (words != "")
words += "and ";
var unitsMap = new[] { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
var tensMap = new[] { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };
if (number < 20)
words += unitsMap[number];
else
{
words += tensMap[number / 10];
if ((number % 10) > 0)
words += "-" + unitsMap[number % 10];
}
}
return words;
}
Make sure that in the path generated in your logs -in your case:
/Users/MyApplicationName/app/build/outputs/apk/app-debug.apk
folder "outputs" indeed has an "apk" folder.
That was my problem, if it's not there, you will need to run the "assembleRelease" task in gradle by following the below screenshot;
There are two types of drop down lists available (I am not sure since which version).
ActiveX Drop Down
You can set the column widths, so your hidden column can be set to 0.
Form Drop Down
You could set the drop down range to a hidden sheet and reference the cell adjacent to the selected item. This would also work with the ActiveX type control.
<script type = "text/javascript">
function get_values(input_id)
{
var input = document.getElementById(input_id).value;
document.write(input);
}
</script>
<!--Insert more code here-->
<input type = "text" id = "textfield">
<input type = "button" onclick = "get('textfield')" value = "submit">
Next time you ask a question here, include more detail and what you have tried.
getWeekOfYear: function(date) {
var target = new Date(date.valueOf()),
dayNumber = (date.getUTCDay() + 6) % 7,
firstThursday;
target.setUTCDate(target.getUTCDate() - dayNumber + 3);
firstThursday = target.valueOf();
target.setUTCMonth(0, 1);
if (target.getUTCDay() !== 4) {
target.setUTCMonth(0, 1 + ((4 - target.getUTCDay()) + 7) % 7);
}
return Math.ceil((firstThursday - target) / (7 * 24 * 3600 * 1000)) + 1;
}
Following code is timezone-independent (UTC dates used) and works according to the https://en.wikipedia.org/wiki/ISO_8601
Use the following regular expression to validate:
var date_regex = /^(0[1-9]|1[0-2])\/(0[1-9]|1\d|2\d|3[01])\/(19|20)\d{2}$/;
if (!(date_regex.test(testDate))) {
return false;
}
This is working for me for MM/dd/yyyy.
One issue with REPLACE
will be where city names contain the district name. You can use something like.
SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM dbo.tblOrtsteileGeo O
JOIN dbo.Cities C
ON C.foo = O.foo
WHERE O.GKZ = '06440004'
This is an altered version of @Martin Thoma's answer for GTK3. I found that the original solution resulted in the process never ending and my terminal hung when I called the script. Changing the script to the following resolved the issue for me.
#!/usr/bin/python3
from gi.repository import Gtk, Gdk
import sys
from time import sleep
class Hello(Gtk.Window):
def __init__(self):
super(Hello, self).__init__()
clipboardText = sys.argv[1]
clipboard = Gtk.Clipboard.get(Gdk.SELECTION_CLIPBOARD)
clipboard.set_text(clipboardText, -1)
clipboard.store()
def main():
Hello()
if __name__ == "__main__":
main()
You will probably want to change what clipboardText gets assigned to, in this script it is assigned to the parameter that the script is called with.

The debug log may provide some insight. I'm using v3.3.4.0, your experience may differ but should be similar. From the settings menu choose 'About Github Desktop...'. Click the link to view the debug log. In my case there was a very clear error:
*** fatal error - cygheap base mismatch detected - 0x1157408/0x1167408. This problem is probably due to using incompatible versions of the cygwin DLL.
It even provided some helpful tips to solve the problem.
I'm not sure why this information isn't exposed in the error prompt, but at least it was available.
i think you are not pausing the program before it ended so the output you are putting after getting the inpus is not seeing on the screen right?
do:
getchar();
before the end of the program
CASE WHEN is the better option
SELECT
CASE WHEN COLUMN1 = COLUMN2
THEN '1'
ELSE '0'
END
AS MyDesiredResult
FROM Table1
INNER JOIN Table2 ON Table1.PrimaryKey = Table2.ForeignKey
Yes you can infact php is one of the few languages who provide such support..

Hope this will save once one's minutes.
"Reset" is the way to undo changes locally. When committing, you first select changes to include with "git add"--that's called "staging." And once the changes are staged, then you "git commit" them.
To back out from either the staging or the commit, you "reset" the HEAD. On a branch, HEAD is a git variable that points to the most recent commit. So if you've staged but haven't committed, you "git reset HEAD." That backs up to the current HEAD by taking changes off the stage. It's shorthand for "git reset --mixed HEAD~0."
If you've already committed, then the HEAD has already advanced, so you need to back up to the previous commit. Here you "reset HEAD~1" or "reset HEAD^1" or "reset HEAD~" or "reset HEAD^"-- all reference HEAD minus one.
Which is the better symbol, ~ or ^? Think of the ~ tilde as a single stream -- when each commit has a single parent and it's just a series of changes in sequence, then you can reference back up the stream using the tilde, as HEAD~1, HEAD~2, HEAD~3, for parent, grandparent, great-grandparent, etc. (technically it's finding the first parent in earlier generations).
When there's a merge, then commits have more than one parent. That's when the ^ caret comes into play--you can remember because it shows the branches coming together. Using the caret, HEAD^1 would be the first parent and HEAD^2 would be the second parent of a single commit--mother and father, for example.
So if you're just going back one hop on a single-parent commit, then HEAD~ and HEAD^ are equivalent--you can use either one.
Also, the reset can be --soft, --mixed, or --hard. A soft reset just backs out the commit--it resets the HEAD, but it doesn't check out the files from the earlier commit, so all changes in the working directory are preserved. And --soft reset doesn't even clear the stage (also known as the index), so all the files that were staged will still be on stage.
A --mixed reset (the default) also does not check out the files from the earlier commit, so all changes are preserved, but the stage is cleared. That's why a simple "git reset HEAD" will clear off the stage.
A --hard reset resets the HEAD, and it clears the stage, but it also checks out all the files from the earlier commit and so it overwrites any changes.
If you've pushed the commit to a remote repository, then reset doesn't work so well. You can reset locally, but when you try to push to the remote, git will see that your local HEAD is behind the HEAD in the remote branch and will refuse to push. You may be able to force the push, but git really does not like doing that.
Alternatively, you can stash your changes if you want to keep them, check out the earlier commit, un-stash the changes, stage them, create a new commit, and then push that.
This is likely caused by your application's connection pool; not an Oracle DBMS issue. Most connection pools have a validate statement that can execute before giving you the connection. In oracle you would want "Select 1 from dual".
The reason it started occurring after you restarted the server is that the connection pool was probably added without a restart and you are just now experiencing the use of the connection pool for the first time. What is the modification dates on your resource files that deal with database connections?
Validate Query example:
<Resource name="jdbc/EmployeeDB" auth="Container"
validationQuery="Select 1 from dual" type="javax.sql.DataSource" username="dbusername" password="dbpassword"
driverClassName="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:database"
maxActive="8" maxIdle="4"/>
EDIT: In the case of Grails, there are similar configuration options for the grails pool. Example for Grails 1.2 (see release notes for Grails 1.2)
dataSource {
pooled = true
dbCreate = "update"
url = "jdbc:mysql://localhost/yourDB"
driverClassName = "com.mysql.jdbc.Driver"
username = "yourUser"
password = "yourPassword"
properties {
maxActive = 50
maxIdle = 25
minIdle = 5
initialSize = 5
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
maxWait = 10000
}
}
LIKE
is used for pattern matching and =
is used for equality test (as defined by the COLLATION
in use).
=
can use indexes while LIKE
queries usually require testing every single record in the result set to filter it out (unless you are using full text search) so =
has better performance.
import re
url = '<p>Hello World</p><a href="http://example.com">More Examples</a><a href="http://example2.com">Even More Examples</a>'
urls = re.findall('https?://(?:[-\w.]|(?:%[\da-fA-F]{2}))+', url)
>>> print urls
['http://example.com', 'http://example2.com']
You can use text that is only accessible to screen readers by placing it in a span which you hide in an accessible way. Place the x in the CSS which can't be read by screen readers, thus won't confuse, but is visible on the page, and also accessible by keyboard users.
<style>
.hidden {opacity:0; position:absolute; width:0;}
.close {padding:4px 8px; border:1px solid #000; background-color:#fff; cursor:pointer;}
.close:before {content:'\00d7'; color:red; font-size:2em;}
</style>
<button class="close"><span class="hidden">close</span></button>
On windows use the name of the table in quotes:
TABLE "user";
or SELECT * FROM "user";
I did exactly what you're looking for in a very simple way. It is perfectly smooth in Google Chrome and Opera, and almost perfect in Firefox and Safari. Not tested in IE.
function newTab(url)
{
var tab=window.open("");
tab.document.write("<!DOCTYPE html><html>"+document.getElementsByTagName("html")[0].innerHTML+"</html>");
tab.document.close();
window.location.href=url;
}
Fiddle : http://jsfiddle.net/tFCnA/show/
Explanations:
Let's say there is windows A1 and B1 and websites A2 and B2.
Instead of opening B2 in B1 and then return to A1, I open B2 in A1 and re-open A2 in B1.
(Another thing that makes it work is that I don't make the user re-download A2, see line 4)
The only thing you may doesn't like is that the new tab opens before the main page.
Maybe not the most elegant solution, but here's a solution using nested while loops:
def transpose(lst):
newlist = []
i = 0
while i < len(lst):
j = 0
colvec = []
while j < len(lst):
colvec.append(lst[j][i])
j = j + 1
newlist.append(colvec)
i = i + 1
return newlist
Usually this kind of error comes when you do DateTime conversion or parsing. Check the calendar setting in the server where the application is hosted, mainly the time zone and short date format, and ensure it's set to the right time zone for the location. Hope this would resolve the issue.
As of .NET Core 2.2, TargetMigration
seems to be gone:
get-help Update-Database
NAME
Update-Database
SYNOPSIS
Updates the database to a specified migration.
SYNTAX
Update-Database [[-Migration] <String>] [-Context <String>] [-Project <String>] [-StartupProject <String>] [<CommonParameters>]
DESCRIPTION
Updates the database to a specified migration.
RELATED LINKS
Script-Migration
about_EntityFrameworkCore
REMARKS
To see the examples, type: "get-help Update-Database -examples".
For more information, type: "get-help Update-Database -detailed".
For technical information, type: "get-help Update-Database -full".
For online help, type: "get-help Update-Database -online"
So this works for me now:
Update-Database -Migration 20180906131107_xxxx_xxxx
As well as (no -Migration
switch):
Update-Database 20180906131107_xxxx_xxxx
On an added note, you can no longer cleanly delete migration folders without putting your Model Snapshot out of sync. So if you learn this the hard way and wind up with an empty migration where you know there should be changes, you can run (no switches needed for the last migration):
Remove-migration
It will clean up the mess and put you back where you need to be, even though the last migration folder was deleted manually.
I did
$(".navbar-toggle").click(function(event) {
$(".navbar-collapse").toggle('in');
});
You can use this:
#!/bin/bash
file="file_you_want_to_delete"
if [ -f "$file" ] ; then
rm "$file"
fi
The solution is the /Y
switch:
xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y
This can be used in automation scripts if you don't need all tables in all schemas:
for table in $(psql -qAntc '\dt' | cut -d\| -f2); do
...

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if
as a top-level step in declarative, so you need to wrap it in a script
step. here's a working declarative version:
pipeline {
agent any
stages {
stage('test') {
steps {
sh 'echo hello'
}
}
stage('test1') {
steps {
sh 'echo $TEST'
}
}
stage('test3') {
steps {
script {
if (env.BRANCH_NAME == 'master') {
echo 'I only execute on the master branch'
} else {
echo 'I execute elsewhere'
}
}
}
}
}
}
you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!
ViewTreeObserver
and onWindowFocusChanged()
are not so necessary at all.
If you inflate the TextView
as layout and/or put some content in it and set LayoutParams
then you can use getMeasuredHeight()
and getMeasuredWidth()
.
BUT you have to be careful with LinearLayouts
(maybe also other ViewGroups
). The issue there is, that you can get the width and height after onWindowFocusChanged()
but if you try to add some views in it, then you can't get that information until everything have been drawn. I was trying to add multiple TextViews
to LinearLayouts
to mimic a FlowLayout
(wrapping style) and so couldn't use Listeners
. Once the process is started, it should continue synchronously. So in such case, you might want to keep the width in a variable to use it later, as during adding views to layout, you might need it.
You can also use the Secure Template Overloads, they will help you replace the unsecure calls with secure ones anywhere it is possible to easily deduce buffer size (static arrays).
Just add the following:
#define _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES 1
Then fix the remaining warnings by hand, by using the _s functions.
Text inputs do not fire the change
event until they lose focus. Click outside of the input and the alert will show.
If the callback should fire before the text input loses focus, use the .keyup()
event.
If you are using vscode's terminal then it might not work even if you do the environment variable thing, test by typing
git
Restart vscode, it should work.
If you are expecting double, decimal, float, integer
why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).
instead of (double)value
use decimal.Parse(value.ToString())
or Convert.ToDecimal(value)
It worked for me by adding a simple sleep timeout of 20 sec. This might happen if your source directory is still writing. Hence put a sleep so that the backup would finish and then tar should work fine. This also helped me in getting the right exit status.
sleep 20
tar -czf ${DB}.${DATE}.tgz ./${DB}.${DATE}
Simply remove the Microsoft SQL Server Management Studio Express 2005 from control panel
This happened to me by having a link to external js outside the head just before the end of the body section. You know, one of these:
<script src="http://somesite.net/js/somefile.js">
It did not have anything to do with JQuery.
You would probably see the same doing something like this:
var script = $("<script></script>");
script.attr("src", basepath + "someotherfile.js");
$(document.body).append(script);
But I haven't tested that idea.
On DataTable 1.9.x:
$('.dataTable').dataTable({
'aoColumnDefs': [{
'bSortable': false,
'aTargets': [-1], /* 1st colomn, starting from the right */
}]
});
While on 1.10.x
$('.dataTable').dataTable({
columnDefs: [{ orderable: false, "targets": -1 }] /* -1 = 1st colomn, starting from the right */
});
For users who facing this isssue in .NET Core 3.0, this could be related to a breaking change that made in .NET Core 3.0, to resolve it just set EmbeddedResourceUseDependentUponConvention
to false in your project csproj:
<PropertyGroup>
<EmbeddedResourceUseDependentUponConvention>false</EmbeddedResourceUseDependentUponConvention>
</PropertyGroup>
Because it's an integer. You need to declare them as floating point numbers or decimals, or cast to such in the calculation.
You are not seeding the number.
Use This:
#include <iostream>
#include <ctime>
using namespace std;
int main()
{
srand(static_cast<unsigned int>(time(0)));
cout << (rand() % 100) << endl;
return 0;
}
You only need to seed it once though. Basically don't seed it every random number.
You state in the comments that the returned JSON is this:
{
"dstOffset" : 3600,
"rawOffset" : 36000,
"status" : "OK",
"timeZoneId" : "Australia/Hobart",
"timeZoneName" : "Australian Eastern Daylight Time"
}
You're telling Gson that you have an array of Post
objects:
List<Post> postsList = Arrays.asList(gson.fromJson(reader,
Post[].class));
You don't. The JSON represents exactly one Post
object, and Gson is telling you that.
Change your code to be:
Post post = gson.fromJson(reader, Post.class);
First of all, there's no such thing as a JSON object. What you've got in your question is a JavaScript object literal (see here for a great discussion on the difference). Here's how you would go about serializing what you've got to JSON though:
I would use an anonymous type filled with your results
type:
string json = JsonConvert.SerializeObject(new
{
results = new List<Result>()
{
new Result { id = 1, value = "ABC", info = "ABC" },
new Result { id = 2, value = "JKL", info = "JKL" }
}
});
Also, note that the generated JSON has result items with id
s of type Number
instead of strings. I doubt this will be a problem, but it would be easy enough to change the type of id
to string
in the C#.
I'd also tweak your results
type and get rid of the backing fields:
public class Result
{
public int id { get ;set; }
public string value { get; set; }
public string info { get; set; }
}
Furthermore, classes conventionally are PascalCased
and not camelCased
.
Here's the generated JSON from the code above:
{
"results": [
{
"id": 1,
"value": "ABC",
"info": "ABC"
},
{
"id": 2,
"value": "JKL",
"info": "JKL"
}
]
}
Not perfect but I think it must be safest. Add nl2br:
$skuList = explode('<br />', nl2br($_POST['skuList']));
IO.Path.GetFullPath(@"..\..")
If you clear the "bin\Debug\
" in the Project properties -> Build -> Output path, then you can just use AppDomain.CurrentDomain.BaseDirectory
The following can be used to get the date:
function date_date() {
var date = new Date();
var year = date.getYear();
var month = date.getMonth() + 1; if(month.toString().length==1){var month =
'0'+month;}
var day = date.getDate(); if(day.toString().length==1){var day = '0'+day;}
var hour = date.getHours(); if(hour.toString().length==1){var hour = '0'+hour;}
var minu = date.getMinutes(); if(minu.toString().length==1){var minu = '0'+minu;}
var seco = date.getSeconds(); if(seco.toString().length==1){var seco = '0'+seco;}
var date = year+'·'+month+'·'+day+'·'+hour+'·'+minu+'·'+seco;
Logger.log(date);
}
The objdump
tool can tell you this information. If you invoke objdump
with the -x
option, to get it to output all headers then you'll find the shared object dependencies right at the start in the "Dynamic Section".
For example running objdump -x /usr/lib/libXpm.so.4
on my system gives the following information in the "Dynamic Section":
Dynamic Section:
NEEDED libX11.so.6
NEEDED libc.so.6
SONAME libXpm.so.4

VERSYM 0x00000000000019bc
RELACOUNT 0x000000000000001b
The direct shared object dependencies are listing as 'NEEDED' values. So in the example above, libXpm.so.4
on my system just needs libX11.so.6
and libc.so.6
.
It's important to note that this doesn't mean that all the symbols needed by the binary being passed to objdump
will be present in the libraries, but it does at least show what libraries the loader will try to load when loading the binary.
You can use both Font Awesome and Github Octicons as a free alternative for Glyphicons.
Bootstrap 4 also switched from Less to Sass, so you might integerate the font's Sass (SCSS) into you build process, to create a single CSS file for your projects.
Also see https://getbootstrap.com/docs/4.1/getting-started/build-tools/ to find out how to set up your tooling:
/bootstrap
directory and run npm install
to install our local dependencies listed in package.json.gem install bundler
, and finally run bundle install
. This will install all Ruby dependencies, such as Jekyll and plugins.Font Awesome
font-awesome/scss
folder into your /bootstrap folderOpen your SCSS /bootstrap/bootstrap.scss
and write down the following SCSS code at the end of this file:
$fa-font-path: "../fonts";
@import "../font-awesome/scss/font-awesome.scss";
Notice that you also have to copy the font file from font-awesome/fonts
to dist/fonts
or any other public folder set by $fa-font-path
in the previous step
npm run dist
to recompile your code with Font-AwesomeGithub Octicons
octicons
folder into your /bootstrap
folderOpen your SCSS /bootstrap/bootstrap.scss
and write down the following SCSS code at the end of this file:
$fa-font-path: "../fonts";
@import "../octicons/octicons/octicons.scss";
Notice that you also have to copy the font file from font-awesome/fonts
to dist/fonts
or any other public folder set by $fa-font-path
in the previous step
npm run dist
to recompile your code with OcticonsGlyphicons
On the Bootstrap website you can read:
Includes over 250 glyphs in font format from the Glyphicon Halflings set. Glyphicons Halflings are normally not available for free, but their creator has made them available for Bootstrap free of cost. As a thank you, we only ask that you include a link back to Glyphicons whenever possible.
As I understand you can use these 250 glyphs free of cost restricted for Bootstrap but not limited to version 3 exclusive. So you can use them for Bootstrap 4 too.
bootstrap/scss
folder$bootstrap-sass-asset-helper: false;
$icon-font-name: 'glyphicons-halflings-regular';
$icon-font-svg-id: 'glyphicons_halflingsregular';
$icon-font-path: '../fonts/';
@import "glyphicons";
npm run dist
to recompile your code with GlyphiconsNotice that Bootstrap 4 requires the post CSS Autoprefixer for compiling. When you are using a static Sass compiler to compile your CSS you should have to run the Autoprefixer afterwards.
You can find out more about mixing with the Bootstrap 4 SCSS in here.
You can also use Bower to install the fonts above. Using Bower Font Awesome installs your files in bower_components/components-font-awesome/
also notice that Github Octicons sets the octicons/octicons/octicons-.scss
as the main file whilst you should use octicons/octicons/sprockets-octicons.scss
.
All the above will compile all your CSS code including into a single file, which requires only one HTTP request. Alternatively you can also load the Font-Awesome font from CDN, which can be fast too in many situations. Both fonts on CDN also include the font files (using data-uri's, possible not supported for older browsers). So consider which solution best fits your situation depending on among others browsers to support.
For Font Awesome paste the following code into the <head>
section of your site's HTML:
<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
Also try Yeoman generator to scaffold out a front-end Bootstrap 4 Web app to test Bootstrap 4 with Font Awesome or Github Octicons.
One way to do this... As text length increases try to change (decrease) the fontsize of the label text using
Label.adjustsFontSizeToFitWidth = YES;
#testDiv{
/* set green border independently on each side */
border-left: solid green 2px;
border-right: solid green 2px;
border-bottom: solid green 2px;
border-top: solid green 2px;
}
I was in the same boat. Installed Eclipse, realized need CDT.
sudo apt-get install eclipse eclipse-cdt g++
This just adds the CDT package on top of existing installation - no un-installation etc. required.
Regarding the question,
” can someone explain why the
compare()
function exists if a comparison can be made using simple operands?
Relative to <
and ==
, the compare
function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.
As an example of simplicity, for small integer values you can write a compare function like this:
auto compare( int a, int b ) -> int { return a - b; }
which is highly efficient.
Now for a structure
struct Foo
{
int a;
int b;
int c;
};
auto compare( Foo const& x, Foo const& y )
-> int
{
if( int const r = compare( x.a, y.a ) ) { return r; }
if( int const r = compare( x.b, y.b ) ) { return r; }
return compare( x.c, y.c );
}
Trying to express this lexicographic compare directly in terms of <
you wind up with horrendous complexity and inefficiency, relatively speaking.
With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.
I haven't tested every single one of these answers but you don't need to use complicated functions to accomplish this. It's so much easier than that! My code below will work in any office VBA application (Word, Access, Excel, Outlook, etc.) and is very simple. Hope this helps:
''Dimension 2 Arrays
Dim InnerArray(1 To 3) As Variant ''The inner is for storing each column value of the current row
Dim OuterArray() As Variant ''The outer is for storing each row in
Dim i As Byte
i = 1

''Enlarging our outer array to store a/another row
ReDim Preserve OuterArray(1 To i)
''Loading the current row column data in
InnerArray(1) = "My First Column in Row " & i
InnerArray(2) = "My Second Column in Row " & i
InnerArray(3) = "My Third Column in Row " & i
''Loading the entire row into our array
OuterArray(i) = InnerArray
i = i + 1
Loop
''Example print out of the array to the Intermediate Window

For this answer, I refer to querySelector
and querySelectorAll
as querySelector* and to getElementById
, getElementsByClassName
, getElementsByTagName
, and getElementsByName
as getElement*.
querySelector
and getElementById
both return a single element. querySelectorAll
and getElementsByName
both return NodeLists, being newer functions that were added after HTMLCollection went out of fashion. The older getElementsByClassName
and getElementsByTagName
both return HTMLCollections. Again, this is essentially irrelevant to whether the elements are live or static.These concepts are summarized in the following table.
Function | Live? | Type | Time Complexity
querySelector | N | Element | O(n)
querySelectorAll | N | NodeList | O(n)
getElementById | Y | Element | O(1)
getElementsByClassName | Y | HTMLCollection | O(1)
getElementsByTagName | Y | HTMLCollection | O(1)
getElementsByName | Y | NodeList | O(1)
HTMLCollections are not as array-like as NodeLists and do not support .forEach(). I find the spread operator useful to work around this:
[...document.getElementsByClassName("someClass")].forEach()
Every element, and the global document
, have access to all of these functions except for getElementById
and getElementsByName
, which are only implemented on document
.
Chaining getElement* calls instead of using querySelector* will improve performance, especially on very large DOMs. Even on small DOMs and/or with very long chains, it is generally faster. However, unless you know you need the performance, the readability of querySelector* should be preferred. querySelectorAll
is often harder to rewrite, because you must select elements from the NodeList or HTMLCollection at every step. For example, the following code does not work:
document.getElementsByClassName("someClass").getElementsByTagName("div")
because you can only use getElements* on single elements, not collections. For example:
document.querySelector("#someId .someClass div")
could be written as:
document.getElementById("someId").getElementsByClassName("someClass")[0].getElementsByTagName("div")[0]
Note the use of [0]
to get just the first element of the collection at each step that returns a collection, resulting in one element at the end just like with querySelector
.
Since all elements have access to both querySelector* and getElement* calls, you can make chains using both calls, which can be useful if you want some performance gain, but cannot avoid a querySelector that can not be written in terms of the getElement* calls.
Though it is generally easy to tell if a selector can be written using only getElement* calls, there is one case that may not be obvious:
document.querySelectorAll(".class1.class2")
can be rewritten as
document.getElementsByClassName("class1 class2")
Using getElement* on a static element fetched with querySelector* will result in an element that is live with respect to the static subset of the DOM copied by querySelector, but not live with respect to the full document DOM... this is where the simple live/static interpretation of elements begins to fall apart. You should probably avoid situations where you have to worry about this, but if you do, remember that querySelector* calls copy elements they find before returning references to them, but getElement* calls fetch direct references without copying.
Neither API specifies which element should be selected first if there are multiple matches.
Because querySelector* iterates through the DOM until it finds a match (see Main Difference #2), the above also implies that you cannot rely on the position of an element you are looking for in the DOM to guarantee that it is found quickly - the browser may iterate through the DOM backwards, forwards, depth first, breadth first, or otherwise. getElement* will still find elements in roughly the same amount of time regardless of their placement.
I have been struggling for days finally the solution which worked for me is given below. I had to make the window.print()
for PDF in new window needs to work.
var xhr = new XMLHttpRequest();
xhr.open('GET', pdfUrl, true);
xhr.responseType = 'blob';
xhr.onload = function(e) {
if (this['status'] == 200) {
var blob = new Blob([this['response']], {type: 'application/pdf'});
var url = URL.createObjectURL(blob);
var printWindow = window.open(url, '', 'width=800,height=500');
printWindow.print()
}
};
xhr.send();
Some notes on loading PDF & printing in a new window.
window.print()
you will get empty print or elements which excludes iframe
. But you can trigger print manually, which will work.Use this:
var table = $(selector).dataTables();
table.api().draw(false);
or
var table = $(selector).DataTables();
table.draw(false);
You can try to make your own drawable for the hamburger icon like this.
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportHeight="24.0"
android:viewportWidth="24.0">
<path
android:fillColor="#ffffff"
android:pathData="M3,18h18v-2L3,16v2zM3,13h18v-2L3,11v2zM3,6v2h18L21,6L3,6z" />
</vector>
Then in your fragment/activity,
getSupportActionBar().setHomeAsUpIndicator(R.drawable.as_above);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
For other drawables, this might help: https://github.com/google/material-design-icons/blob/master/navigation/drawable-anydpi-v21/
Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:
label1.txt = "Pizza"
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();
If I already know its a Pizza there's no advantage to:
p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();
but I see a huge advantage to the Magic method if it exists.
Update:
The original answer makes it difficult (and in some cases impossible) to correctly handle promise rejections. The correct solution is to use Promise.all
:
const [someResult, anotherResult] = await Promise.all([someCall(), anotherCall()]);
Original answer:
Just make sure you call both functions before you await either one:
// Call both functions
const somePromise = someCall();
const anotherPromise = anotherCall();
// Await both promises
const someResult = await somePromise;
const anotherResult = await anotherPromise;
import glob
import os
root_dir = <root_dir_here>
for filename in glob.iglob(root_dir + '**/**', recursive=True):
if os.path.isfile(filename):
with open(filename,'r') as file:
print(file.read())
**/**
is used to get all files recursively including directory
.
if os.path.isfile(filename)
is used to check if filename
variable is file
or directory
, if it is file then we can read that file.
Here I am printing file.
Schema::defaultStringLength(191);
will define the length of all strings 191 by default which may ruin your database. You must not go this way.
Just define the length of any specific column in the database migration class. For example, I'm defining the "name", "username" and "email" in the CreateUsersTable
class as below:
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name', 191);
$table->string('username', 30)->unique();
$table->string('email', 191)->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
I have changed the implementation of it to get your problem solved, I made an object to track the old changes and compare it with that. You can use it to solve your issue.
Here I created a method, in which the old value will be stored in a separate variable and, which then will be used in a watch.
new Vue({
methods: {
setValue: function() {
this.$data.oldPeople = _.cloneDeep(this.$data.people);
},
},
mounted() {
this.setValue();
},
el: '#app',
data: {
people: [
{id: 0, name: 'Bob', age: 27},
{id: 1, name: 'Frank', age: 32},
{id: 2, name: 'Joe', age: 38}
],
oldPeople: []
},
watch: {
people: {
handler: function (after, before) {
// Return the object that changed
var vm = this;
let changed = after.filter( function( p, idx ) {
return Object.keys(p).some( function( prop ) {
return p[prop] !== vm.$data.oldPeople[idx][prop];
})
})
// Log it
vm.setValue();
console.log(changed)
},
deep: true,
}
}
})
See the updated codepen
You can use lodash's method, it works for string, number and boolean type
_.compact([0, 1, false, 2, '', 3]);
// => [1, 2, 3]
Try this one
where datediff(month, datetime_column, getdate()) <= 6
To exclude or filter out future dates
where datediff(month, datetime_column, getdate()) between 0 and 6
This part datediff(month, datetime_column, getdate())
will get the month difference in number of current date and Datetime_Column and will return Rows like:
Result
1
2
3
4
5
6
7
8
9
10
This is Our final condition to get last 6 months data
where result <= 6
Before installing libgtk2.0-dev and pkg-config or libqt4-dev. Make sure that you have uninstalled opencv. You can confirm this by running import cv2 on your python shell. If it fails, then install the needed packages and re-run cmake .
Just modify one of the returned entities:
Customer c = (from x in dataBase.Customers
where x.Name == "Test"
select x).First();
c.Name = "New Name";
dataBase.SaveChanges();
Note, you can only update an entity (something that extends EntityObject, not something that you have projected using something like select new CustomObject{Name = x.Name}
Implementation wise you will often see inside super() statement in subclasses constructors, something like:
public class A extends AbstractB{
public A(...){
super(String constructorArgForB, ...);
...
}
}
var currentDateTime = dateTime.Now();
var date=currentDateTime.Date;
Sort of already answered this in the comments, but just so this question has an answer, the problem was resolved through running:
sudo apt-get install python3-pymysql
Other way could be this one:
driver.FindElement(By.XPath(".//*[@id='examp']/form/select[1]/option[3]")).Click();
and you can change the index in option[x] changing x by the number of element that you want to select.
I don't know if it is the best way but I hope that help you.
With SQL 2012 and later, you could use TRY_CAST
/TRY_CONVERT
to try converting to a numeric type, e.g. TRY_CAST(answer AS float) IS NOT NULL
-- note though that this will match scientific notation too (1+E34). (If you use decimal
, then scientific notation won't match)

if using react:
const html = ReactDOM.findDOMNode(document.getElementsByTagName('html')[0]).outerHTML;
after some test: If you send an email to an outlook client, and the subject is >77 chars, and it needs to use "=?ISO"
inside the subject (in my case because of accents) then OutLook will "cut" the subject in the middle of it and mesh it all that comes after, including body text, attaches, etc... all a mesh!
I have several examples like this one:
Subject: =?ISO-8859-1?Q?Actas de la obra N=BA.20100154 (Expediente N=BA.20100182) "NUEVA RED FERROVIARIA.=
TRAMO=20BEASAIN=20OESTE(Pedido=20PC10/00123-125),=20BEASAIN".?=
To:
As you see, in the subject line it cutted on char 78 with a "=" followed by 2 or 3 line feeds, then continued with the rest of the subject baddly.
It was reported to me from several customers who all where using OutLook, other email clients deal with those subjects ok.
If you have no ISO on it, it doesn't hurt, but if you add it to your subject to be nice to RFC, then you get this surprise from OutLook. Bit if you don't add the ISOs, then iPhone email will not understand it(and attach files with names using such characters will not work on iPhones).
No, IIRC there is no getopt() on Windows.
Boost, however, has the program_options library... which works okay. It will seem like overkill at first, but it isn't terrible, especially considering it can handle setting program options in configuration files and environment variables in addition to command line options.
There is U+1F50D LEFT-POINTING MAGNIFYING GLASS () and U+1F50E RIGHT-POINTING MAGNIFYING GLASS ().

They are, however not supported by many fonts (fileformat.info only lists a few fonts as supporting the Codepoint with a proper glyph).
Also note that they are outside of the BMP, so some Unicode-capable software might have problems rendering them, even if they have fonts that support them.
Generally Unicode Glyphs can be searched using a site such as fileformat.info. This searches "only" in the names and properties of the Unicode glyphs, but they usually contain enough metadata to allow for good search results (for this answer I searched for "glass" and browsed the resulting list, for example)
Take the attribute
app:layout_behavior="@string/appbar_scrolling_view_behavior"
off the RecyclerView
and put it on the FrameLayout
that you are trying to show under the Toolbar
.
I've found that one important thing the scrolling view behavior does is to layout the component below the toolbar. Because the FrameLayout
has a descendant that will scroll (RecyclerView
), the CoordinatorLayout
will get those scrolling events for moving the Toolbar
.
One other thing to be aware of: That layout behavior will cause the FrameLayout
height to be sized as if the Toolbar
is already scrolled, and with the Toolbar
fully displayed the entire view is simply pushed down so that the bottom of the view is below the bottom of the CoordinatorLayout
.
This was a surprise to me. I was expecting the view to be dynamically resized as the toolbar is scrolled up and down. So if you have a scrolling component with a fixed component at the bottom of your view, you won't see that bottom component until you have fully scrolled the Toolbar
.
So when I wanted to anchor a button at the bottom of the UI, I worked around this by putting the button at the bottom of the CoordinatorLayout
(android:layout_gravity="bottom"
) and adding a bottom margin equal to the button's height to the view beneath the toolbar.
span.login-text {
font-size: 22px;
display:table;
margin-left: auto;
margin-right: auto;
}
<span class="login-text">Welcome To .....CMP</span>
For me it worked very well. try this also
If you just deleted the branch, you will see something like this in your terminal:
Deleted branch branch_name(was e562d13)
- where e562d13 is a unique ID (a.k.a. the "SHA" or "hash"), with this you can restore the deleted branch.
To restore the branch, use:
git checkout -b <branch_name> <sha>
for example:
git checkout -b branch_name e562d13
In python the with
keyword is used when working with unmanaged resources (like file streams). It is similar to the using
statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally
blocks.
From Python Docs:
The
with
statement clarifies code that previously would usetry...finally
blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.The
with
statement is a control-flow structure whose basic structure is:with expression [as variable]: with-block
The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has
__enter__()
and__exit__()
methods).
Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with
with using
.
Kill Multiple Processes From the Command Line The first thing you’ll need to do is open up a command prompt, and then use the taskkill command with the following syntax:
taskkill /F /IM <processname.exe> /T
These parameters will forcibly kill any process matching the name of the executable that you specify. For instance, to kill all iexplore.exe processes, we’d use:
taskkill /F /IM iexplore.exe
I think this one will answer your question :P

I thought that since the js file was already loaded, that I didn't need to load/enqueue it again in the separate add_ajax function.
But this must be necessary, or I did this and it's now working.
Hopefully will help someone else.
Here is the corrected code from the question:
// code to load jquery - working fine
// code to load javascript file - working fine
// ENABLE AJAX :
function add_ajax()
{
wp_enqueue_script(
'function',
'http://host/blog/wp-content/themes/theme/js.js',
array( 'jquery' ),
'1.0',
1
);
wp_localize_script(
'function',
'ajax_script',
array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}
$dirName = get_stylesheet_directory(); // use this to get child theme dir
require_once ($dirName."/ajax.php");
add_action("wp_ajax_nopriv_function1", "function1"); // function in ajax.php
add_action('template_redirect', 'add_ajax');
This error indicates your package_name
in your google-services.json
might be wrong. I personally had this issue when I used
buildTypes {
...
debug {
applicationIdSuffix '.debug'
}
}
in my build.gradle
. So, when I wanted to debug, the name of the application was ("all of a sudden") app.something.debug
instead of app.something
. I was able to run the debug when I changed the said package_name
...
Another option is to run the package in 32 bit mode. Click on the solution => properties =? Debugging => Set run in 64 bit to false.
No need of JQuery simply you can do
if(yourObject['email']){
// what if this property exists.
}
as with any value for email
will return you true
, if there is no such property or that property value is null
or undefined
will result to false
Here's my answer -- Phil's solution fails for single letter domains like "[email protected]". Believe it or not, that's used =) (goes to centurylink, for instance).
Phil's answer is also going to work only with PCRE standard... so C# will take it, but javascript is going to bomb. It's too complex for javascript. So you can't use Phil's solution for mvc validation attributes.
Here's my regex. It'll work nicely with MVC validation attributes.
- Everything before the @ is simplified, so that at least javascript will work. I'm okay relaxing validation here as long as exchange server doesn't give me a 5.1.3.
- Everything after the @ is Phil's solution modified for single letter domains.
public const string EmailPattern =
@"^\s*[\w\-\+_']+(\.[\w\-\+_']+)*\@[A-Za-z0-9]([\w\.-]*[A-Za-z0-9])?\.[A-Za-z][A-Za-z\.]*[A-Za-z]$";
For people suggesting using system.net.mail MailMessage(), that thing is WAY to flexible. Sure, C# will accept the email, but then exchange server will bomb with 5.1.3 runtime error as soon as you try to send the email.
<script>
is HTML 5.
<script type='text/javascript'>
is HTML 4.x (and XHTML 1.x).
<script language="javascript">
is HTML 3.2.
Is it different for different webservers?
No.
when I did an offline javascript test, i realised that i need the
<script type = 'text/javascript'>
tag.
That isn't the case. Something else must have been wrong with your test case.
Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n
will work.
If you use anything else you will cause issues with cut and paste on Windows platforms.
The line breaks will be canonicalised by windows browsers when the form is submitted, but if you send the form down to the browser with \n
linebreaks, you will find that the text will not copy and paste correctly between for example notepad and the textarea.
Interestingly, in spite of the Unix line end convention being \n
, the standard in most text-based network protocols including HTTP, SMTP, POP3, IMAP, and so on is still \r\n
. Yes, it may not make a lot of sense, but that's history and evolving standards for you!
Updated for everyone reading this in 2013 and later:
This answer has a lot of SEO, but all the answers are severely out of date and depend on libraries to do things that all current browsers do out of the box.
fieldNameElement.textContent = "New text";
This could be due to a face palm moment: if you switch between several clones it is easy to find yourself in the wrong source tree trying to pull a non-existent branch. It is easier when the clones have similar names, or the repos are distinct clones for the same project from each of multiple contributors. A new git clone would obviously seem to solve that "problem" when the real problem is losing focus or working context or both.
The question relates to serving via artisan and so Jrop's answer is ideal in that case. I.e, error_log
logging to the apache log.
However, if your serving via a standard web server then simply use the Laravel specific logging functions:
\Log::info('This is some useful information.');
\Log::warning('Something could be going wrong.');
\Log::error('Something is really going wrong.');
With current versions of laravel like this for info:
info('This is some useful information.');
This logs to Laravel's log file located at /laravel/storage/logs/laravel-<date>.log
(laravel 5.0). Monitor the log - linux/osx: tail -f /laravel/storage/logs/laravel-<date>.log
$time = 30 * 60; //30 minutes
$start_time = date('Y-m-d h:i:s', time() - $time);
$end_time = date('Y-m-d h:i:s', time() + $time);
You can try open MVG library, It can be used for multiple interfaces too.
IF you want to filter with NOT IN for a subquery containg NULLs justcheck for not null

I had the same issue with oracle returning scientic notation, but I needed the actual number for a url. I just used a PHP trick by subtracting zero, and I get the correct number.
for example 5.4987E7 is the val.
newval = val - 0;
newval now equals 54987000
This was happening in my project because I was using an XML resource to set the version code.
AndroidManifest.xml:
android:versionCode="@integer/app_version_code"
app.xml:
<integer name="app_version_code">64</integer>
This wasn't a problem in prior versions of adb
, however, as of platform-tools
r16 this is no longer being resolved to the proper integer. You can either force the re-install using adb -r
or avoid the issue entirely by using a literal in the manifest:
android:versionCode="64"
Customize com.facebook.widget.LoginButton

An improved version of Burke's answer that lets you do CONFIG.MY_CONST
instead of CONFIG.get('MY_CONST')
.
It requires IE9+ or a real web browser.
var CONFIG = (function() {
var constants = {
'MY_CONST': 1,
'ANOTHER_CONST': 2
};
var result = {};
for (var n in constants)
if (constants.hasOwnProperty(n))
Object.defineProperty(result, n, { value: constants[n] });
return result;
}());
* The properties are read-only, only if the initial values are immutable.
Unless you want to go the VBA route to work out the Tab name, the Excel formula is fairly ugly based upon Mid functions, etc. But both these methods can be found here if you want to go that way.
Rather, the way I would do it is:
1) Make one cell on your sheet named, for example, Reference_Sheet
and put in that cell the value "Jan Item" for example.
2) Now, use the Indirect
function like:
=INDIRECT(Reference_Sheet&"!J3")
3) Now, for each month's sheet, you just have to change that one Reference_Sheet
cell.
Hope this gives you what you're looking for!
If the undefined's are implicit then you can do:
var len = 0;
for (var i in arr) { len++ };
undefined's are implicit if you don't set them explicitly
//both are a[0] and a[3] are explicit undefined
var arr = [undefined, 1, 2, undefined];
arr[6] = 3;
//now arr[4] and arr[5] are implicit undefined
delete arr[1]
//now arr[1] is implicit undefined
arr[2] = undefined
//now arr[2] is explicit undefined
I haven't had to do this, so take this with a grain of salt and a big helping of "test, test, test".
What happens if (in a safe controlled test environment) you directly modify the Host
column in the mysql.user
and probably mysql.db
tables? (E.g., with an update
statement.) I don't think MySQL uses the user's host as part of the password encoding (the PASSWORD
function doesn't suggest it does), but you'll have to try it to be sure. You may need to issue a FLUSH PRIVILEGES
command (or stop and restart the server).
For some storage engines (MyISAM, for instance), you may also need to check/modify the .frm
file any views that user has created. The .frm
file stores the definer, including the definer's host. (I have had to do this, when moving databases between hosts where there had been a misconfiguration causing the wrong host to be recorded...)
you could use setAttribute
.
Example: For adding one class:
document.getElementById('main').setAttribute("class","classOne");
For multiple classes:
document.getElementById('main').setAttribute("class", "classOne classTwo");
Sharing my solution here, based on Chris' answer. Hope it can help others.
I needed to dynamically append child elements into my JSX, but in a simpler way than conditional checks in my return statement. I want to show a loader in the case that the child elements aren't ready yet. Here it is:
export class Settings extends React.PureComponent {
render() {
const loading = (<div>I'm Loading</div>);
let content = [];
let pushMessages = null;
let emailMessages = null;
if (this.props.pushPreferences) {
pushMessages = (<div>Push Content Here</div>);
}
if (this.props.emailPreferences) {
emailMessages = (<div>Email Content Here</div>);
}
// Push the components in the order I want
if (emailMessages) content.push(emailMessages);
if (pushMessages) content.push(pushMessages);
return (
<div>
{content.length ? content : loading}
</div>
)
}
Now, I do realize I could also just put {pushMessages}
and {emailMessages}
directly in my return()
below, but assuming I had even more conditional content, my return()
would just look cluttered.
checkout: window.print() not working in IE
Working sample: http://jsfiddle.net/Q5Xc9/1/
realpath <path to the symlink file>
should do the trick.
The command in wfg5475's answer is working properly, just need to add one thing to show only files in a directory & sub directory:
ls -ltraR |egrep -v '\.$|\.\.|\.:|\.\/|total|^d' |sed '/^$/d'
Added one thing: ^d
to ignore the all directories from the listing outputs
Consider this CodeProject article/project: LINQ TO CSV.
It will enable you to create a custom class that is shaped like your .csv file's columns. You'd then consume the CSV and bind to your DataGridView.
Dim cc As new CsvContext()
Dim inputFileDescription As New CsvFileDescription() With { _
.SeparatorChar = ","C, _
.FirstLineHasColumnNames = True _
}
Dim products As IEnumerable(Of Product) = _
cc.Read(Of Product)("products.csv", inputFileDescription)
' query from CSV, load into a new class of your own
Dim productsByName = From p In products
Select New CustomDisplayClass With _
{.Name = p.Name, .SomeDate = p.SomeDate, .Price = p.Price}, _
Order By p.Name
myDataGridView1.DataSource = products
myDataGridView1.DataBind()
xhr.file = file;
; the file object is not supposed to be attached this way.xhr.send(file)
doesn't send the file. You have to use the FormData
object to wrap the file into a multipart/form-data
post data object:
var formData = new FormData();
formData.append("thefile", file);
xhr.send(formData);
After that, the file can be access in $_FILES['thefile']
(if you are using PHP).
Remember, MDC and Mozilla Hack demos are your best friends.
EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.
You should be able to set the server.session.timeout
in your application.properties file.
ref: http://docs.spring.io/spring-boot/docs/1.4.x/reference/html/common-application-properties.html
You can't. Variables defined inside a method are local to that method.
If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).
Looks like you're using instance methods instead of static ones.
If you don't want to create an object, you should declare all your methods static, so something like
private static void methodName(Argument args...)
If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.
private static int[][] array = new int[3][5];
Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.
Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.
Here's a final (shortened) example of what your code should be like:
public class Test3 {
//Use this array in your methods
private static int[][] scores = new int[3][5];
/* Rather than just "Scores" name it so people know what
* to expect
*/
private static void createScores() {
//Code...
}
//Other methods...
/* Since you're now using static methods, you don't
* have to initialise an object and call its methods.
*/
public static void main(String[] args){
createScores();
MD(); //Don't know what these do
sumD(); //so I'll leave them.
}
}
Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

The trick to using display:none with images is to assign them an id. This was there is not a lot of code needed to make it work. Here is an example using media queries and 3 stylesheets. One for phone, one for tablet, and one for desktop. I have 3 images, image of a phone, a tablet, and a desktop. On a phone screen only an image of the phone will display, a tablet will display only the tablet image, a desktop displays on the desktop computer image. Here is a code example to make it work:
Source code:
<div id="content">
<img id="phone" src="images/phone.png" />
<img id="tablet" src="images/tablet.png" />
<img id="desktop" src="images/desktop.png" />
</div>
The phone CSS which doesn't need a media query. Its the img#phone that makes it work:
img#phone {
display: block;
margin: 6em auto 0 auto;
width: 70%;
}
img#tablet {display: none;}
img#desktop {display: none;}
The tablet css:
@media only screen and (min-width: 641px) {
img#phone {display: none;}
img#tablet {
display: block;
margin: 6em auto 0 auto;
width: 70%;
}
}
And the desktop css:
@media only screen and (min-width: 1141px) {
img#tablet {display: none;}
img#desktop {
display: block;
margin: 6em auto 0 auto;
width: 80%;
}
}
Good luck and let me know how it works for you.
You should not define global variables in header files. You can declare them as extern
in header file and define them in a .c
source file.
(Note: In C, int i;
is a tentative definition, it allocates storage for the variable (= is a definition) if there is no other definition found for that variable in the translation unit.)

When you use ANNs, you rarely know about the internals of the systems you want to learn. Some things cannot be learned without a bias. E.g., have a look at the following data: (0, 1), (1, 1), (2, 1), basically a function that maps any x to 1.
If you have a one layered network (or a linear mapping), you cannot find a solution. However, if you have a bias it's trivial!
In an ideal setting, a bias could also map all points to the mean of the target points and let the hidden neurons model the differences from that point.
I fixed this error on my RDS instance by rebooting it from the AWS management console. HTH
[edit: lol downvotes]
You can get this misleading error if you naively try to do this:
[clear] -> Private Key Encrypt -> [encrypted] -> Public Key Decrypt -> [clear]
Encrypting data using a private key is not allowed by design.
You can see from the command line options for open ssl that the only options to encrypt -> decrypt
go in one direction public -> private
.
-encrypt encrypt with public key
-decrypt decrypt with private key
The other direction is intentionally prevented because public keys basically "can be guessed." So, encrypting with a private key means the only thing you gain is verifying the author has access to the private key.
The private key encrypt -> public key decrypt
direction is called "signing" to differentiate it from being a technique that can actually secure data.
-sign sign with private key
-verify verify with public key

On apache page: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html
You have something like this:
URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("www.google.com").setPath("/search")
.setParameter("q", "httpclient")
.setParameter("btnG", "Google Search")
.setParameter("aq", "f")
.setParameter("oq", "");
URI uri = builder.build();
HttpGet httpget = new HttpGet(uri);
System.out.println(httpget.getURI());
Above answers are better but yet for knowledge we have another approch as well, Lets 'catagory' column value changed for an object (@design),
@design.changes.has_key?('catagory')
The .changes will return a hash with key as column's name and values as a array with two values [old_value, new_value] for each columns. For example catagory for above is changed from 'ABC' to 'XYZ' of @design,
@design.changes # => {}
@design.catagory = 'XYZ'
@design.changes # => { 'catagory' => ['ABC', 'XYZ'] }
For references change in ROR
refer to official jquery example: and play with it.
.animate({
width: "70%",
opacity: 0.4,
marginLeft: "0.6in",
fontSize: "3em",
borderWidth: "10px"
}, 1500 );
Alternatively, you can use React conditional rendering.
import { Redirect } from "react-router";
import React, { Component } from 'react';
class UserSignup extends Component {
constructor(props) {
super(props);
this.state = {
redirect: false
}
}
render() {
<React.Fragment>
{ this.state.redirect && <Redirect to="/signin" /> } // you will be redirected to signin route
}
</React.Fragment>
}
Here is an Online Tool for fixing a corrupted serialized string.
I'd like to add that this mostly happens due to a search and replace done on the DB and the serialization data(specially the key length
) doesn't get updated as per the replace and that causes the "corruption".
Nonetheless, The above tool uses the following logic to fix the serialization data (Copied From Here).
function error_correction_serialise($string){
// at first, check if "fixing" is really needed at all. After that, security checkup.
if ( unserialize($string) !== true && preg_match('/^[aOs]:/', $string) ) {
$string = preg_replace_callback( '/s\:(\d+)\:\"(.*?)\";/s', function($matches){return 's:'.strlen($matches[2]).':"'.$matches[2].'";'; }, $string );
}
return $string;
}
You can also try with Object.values
const points = { Neel: 100, Veer: 89, Shubham: 78, Vikash: 67 };_x000D_
_x000D_
const vals = Object.values(points);_x000D_
const max = Math.max(...vals);_x000D_
const min = Math.min(...vals);_x000D_
console.log(max);_x000D_
console.log(min);

The default MidpointRounding.ToEven
, or Bankers' rounding (2.5 become 2, 4.5 becomes 4 and so on) has stung me before with writing reports for accounting, so I'll write a few words of what I found out, previously and from looking into it for this post.
From wikipedia
The origin of the term bankers' rounding remains more obscure. If this rounding method was ever a standard in banking, the evidence has proved extremely difficult to find. To the contrary, section 2 of the European Commission report The Introduction of the Euro and the Rounding of Currency Amounts suggests that there had previously been no standard approach to rounding in banking; and it specifies that "half-way" amounts should be rounded up.
It seems a very strange way of rounding particularly for banking, unless of course banks use to receive lots of deposits of even amounts. Deposit £2.4m, but we'll call it £2m sir.
The IEEE Standard 754 dates back to 1985 and gives both ways of rounding, but with banker's as the recommended by the standard. This wikipedia article has a long list of how languages implement rounding (correct me if any of the below are wrong) and most don't use Bankers' but the rounding you're taught at school:
As @Sugrue I'm also digging out an old thread.
To explain why there is 32768 (I think it should be 32767, but lets believe experimental testing result) characters limitation we need to dig into Windows API.
No matter how you launch program with command line arguments it goes to ShellExecute, CreateProcess or any extended their version. These APIs basically wrap other NT level API that are not officially documented. As far as I know these calls wrap NtCreateProcess, which requires OBJECT_ATTRIBUTES structure as a parameter, to create that structure InitializeObjectAttributes is used. In this place we see UNICODE_STRING
. So now lets take a look into this structure:
typedef struct _UNICODE_STRING {
USHORT Length;
USHORT MaximumLength;
PWSTR Buffer;
} UNICODE_STRING;
It uses USHORT
(16-bit length [0; 65535]) variable to store length. And according this, length indicates size in bytes, not characters. So we have: 65535 / 2 = 32767
(because WCHAR
is 2 bytes long).
There are a few steps to dig into this number, but I hope it is clear.
Also, to support @sunetos answer what is accepted. 8191 is a maximum number allowed to be entered into cmd.exe
, if you exceed this limit, The input line is too long.
error is generated. So, answer is correct despite the fact that cmd.exe
is not the only way to pass arguments for new process.
By POST file uploads are done (commonly, there are also other methods). Look into the method attribute of the form which contains the file-upload field ;)
The lowest limit of any related setting supersedes a higher setting:
See Handling file uploads: Common Pitfals which explains this in detail and how to calculate the values.
This error is a result of the protection level of ClassB
's constructor, not ClassB
itself. Since the name of the constructor is the same as the name of the class* , the error may be interpreted incorrectly. Since you did not specify the protection level of your constructor, it is assumed to be internal
by default. Declaring the constructor public
will fix this problem:
public ClassB() { }
* One could also say that constructors have no name, only a type; this does not change the essence of the problem.
If you want a simple method in your code that returns the milliseconds with datetime:
from datetime import datetime
from datetime import timedelta
start_time = datetime.now()
# returns the elapsed milliseconds since the start of the program
def millis():
dt = datetime.now() - start_time
ms = (dt.days * 24 * 60 * 60 + dt.seconds) * 1000 + dt.microseconds / 1000.0
return ms
I'm super late to this but I didn't like the other answers
For brew run
"$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
You SHOULD NOT use brew
to install node and npm.
I've seen a few places suggested that you should use Homebrew to install Node (like alexpods answer and in this Team Treehouse blog Post) but installing this way you're more prone to run into issues as npm
and brew
are both package managers and you should have a package manager manage another package manager this leads to problems, like this bug offical npm issues Error: Refusing to delete: /usr/local/bin/npm or this Can't uninstall npm module on OSX
You can read more on the topic in DanHerbert's post Fixing npm On Mac OS X for Homebrew Users, where he goes on to say
Also, using the Homebrew installation of npm will require you to use sudo when installing global packages. Since one of the core ideas behind Homebrew is that apps can be installed without giving them root access, this is a bad idea.
I'd use npm; but you really should just follow the install instruction for each modules following the directions on there website as they will be more aware of any issue or bug they have than anyone else
As a side-note, with C# 6.0 you can now combine interpolated strings with the verbatim string literal:
string camlCondition = $@"
<Where>
<Contains>
<FieldRef Name='Resource'/>
<Value Type='Text'>{(string)parameter}</Value>
</Contains>
</Where>";
Try using the html() function.
$('#<%=Label1.ClientID%>').html();
You're also missing the # to make it an ID you're searching for. Without the #, it's looking for a tag type.
In Angular, within HTML itself, you can set focus to input on click of a button.
<button (click)="myInput.focus()">Click Me</button>
<input #myInput></input>
I have solved it this way.
Go to your project file let's say project/name/bin and delete everything within the bin folder. (this will then give you another error which you can solve this way)
then in your visual studio right click project's References folder, to open NuGet Package Manager.
Go to browse and install "DotNetCompilerPlatform".

Following the Jenkins wiki, you'll have to:
chown -R jenkins:jenkins $JENKINS_HOME
JENKINS_HOME is by default located in ~/.jenkins
on a Linux installation, yet to exactly find where it is located, go on the http://your_jenkins_url/configure page and check the value of the first parameter: Home directory
; this is the JENKINS_HOME.
Normally, the best-practice is to set the title on the UIViewController
. By doing this, the UINavigationItem
is also set. Generally, this is better than programmatically allocating and initializing a UINavigationBar
that's not linked to anything.
You miss out on some of the benefits and functionality that the UINavigationBar
was designed for. Here is a link to the documentation that may help you. It discusses the different properties you can set on the actual bar and on a UINavigationItem
.
Just keep in mind:
UINavigationController
's are your friends.
Plotly is missing in this list. I've linked the python binding page. It definitively has animated and interative 3D Charts. And since it is Open Source most of that is available offline. Of course it is working with Jupyter
In Servlet do:
String selectedRole = "rat"; // Or "cat" or whatever you'd like.
request.setAttribute("selectedRole", selectedRole);
Then in JSP do:
<select name="roleName">
<c:forEach items="${roleNames}" var="role">
<option value="${role}" ${role == selectedRole ? 'selected' : ''}>${role}</option>
</c:forEach>
</select>
It will print the selected
attribute of the HTML <option>
element so that you end up like:
<select name="roleName">
<option value="cat">cat</option>
<option value="rat" selected>rat</option>
<option value="unicorn">unicorn</option>
</select>
Apart from the problem: this is not a combo box. This is a dropdown. A combo box is an editable dropdown.
I learned something really useful and fundamental from here.
chaining functions is very usefull in this case which works on most jQuery Functions including on function output too.
It works because output of most jQuery functions are the input objects sets so you can use them right away and make it shorter and smarter

After installing pywin32
Steps to correctly install your module (pywin32)
First search where is your python pip is present
1a. For Example in my case location of pip - C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts
Then open your command prompt and change directory to your pip folder location.
cd C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts
C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts>pip install
pypiwin32
Restart your IDE
All done now you can use the module .
Saw this thread but I wanted to search for IDs that did not match my search. Code to do that:
found = $filter('filter')($scope.fish, {id: '!fish_id'}, false);
This also works in Silverlight 5 (perhaps earlier as well but i haven't tested it). I used the relative source like this and it worked fine.
RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=telerik:RadGridView}"
I have also seen this error when inadvertently naming a module with the same name as one of the standard Python modules. E.g. I had a module called commands
which is also a Python library module. This proved to be difficult to track down as it worked correctly on my local development environment but failed with the specified error when running on Google App Engine.
dynamic data = List<x> val;
List<y> val2 = ((IEnumerable)data).Cast<y>().ToList();
The rowSums function (as Greg mentions) will do what you want, but you are mixing subsetting techniques in your answer, do not use "$" when using "[]", your code should look something more like:
data$new <- rowSums( data[,43:167] )
If you want to use a function other than sum, then look at ?apply for applying general functions accross rows or columns.
Here's my answer:
int[] z = new List<string>()
.Concat(a)
.Concat(b)
.Concat(c)
.ToArray();
This method can be used at initialization level, for example to define a static concatenation of static arrays:
public static int[] a = new int [] { 1, 2, 3, 4, 5 };
public static int[] b = new int [] { 6, 7, 8 };
public static int[] c = new int [] { 9, 10 };
public static int[] z = new List<string>()
.Concat(a)
.Concat(b)
.Concat(c)
.ToArray();
However, it comes with two caveats that you need to consider:
Concat
method creates an iterator over both arrays: it does not create a new array, thus being efficient in terms of memory used: however, the subsequent ToArray
will negate such advantage, since it will actually create a new array and take up the memory for the new array.Concat
would be rather inefficient for large arrays: it should only be used for medium-sized arrays.If aiming for performance is a must, the following method can be used instead:
/// <summary>
/// Concatenates two or more arrays into a single one.
/// </summary>
public static T[] Concat<T>(params T[][] arrays)
{
// return (from array in arrays from arr in array select arr).ToArray();
var result = new T[arrays.Sum(a => a.Length)];
int offset = 0;
for (int x = 0; x < arrays.Length; x++)
{
arrays[x].CopyTo(result, offset);
offset += arrays[x].Length;
}
return result;
}
Or (for one-liners fans):
int[] z = (from arrays in new[] { a, b, c } from arr in arrays select arr).ToArray();
Although the latter method is much more elegant, the former one is definitely better for performance.
For additional info, please refer to this post on my blog.
Today i deep in State Design Pattern. I did and tested ThreadState, which equal (+/-) to Threading in C#, as described in picture from Threading in C#
You can easly add new states, configure moves from one state to other is very easy becouse it incapsulated in state implementation
Implementation and using at: Implements .NET ThreadState by State Design Pattern
You could use the Request.RawUrl
, Request.Url.OriginalString
, Request.Url.ToString()
or Request.Url.AbsoluteUri
.
you should use regular expressions to find all you need:
import re
p = re.compile(r'(\d+)') # a pattern for a number
for line in file :
if num in p.findall(line) :
print line
regular expression will return you all numbers in a line as a list, for example:
>>> re.compile(r'(\d+)').findall('123kh234hi56h9234hj29kjh290')
['123', '234', '56', '9234', '29', '290']
so you don't match '200' or '220' for '20'.
I thought my issue was due to my machine.config per answers I found online but the culprit turned out to be in the project's web.config that was clearing out the DbProviderFactories.

<DbProviderFactories>
<clear />

</DbProviderFactories>
</system.data>
Your executable's working directory is probably set to something other than the directory where it is saved. Check your IDE settings.
I'm not sure about the syntax of your specific commands (e.g., vagrant, etc), but in general...
Just register Ansible's (not-normally-shown) JSON output to a variable, then display each variable's stdout_lines
attribute:
- name: Generate SSH keys for vagrant user
user: name=vagrant generate_ssh_key=yes ssh_key_bits=2048
register: vagrant
- debug: var=vagrant.stdout_lines
- name: Show SSH public key
command: /bin/cat $home_directory/.ssh/id_rsa.pub
register: cat
- debug: var=cat.stdout_lines
- name: Wait for user to copy SSH public key
pause: prompt="Please add the SSH public key above to your GitHub account"
register: pause
- debug: var=pause.stdout_lines
Statements a == object2
and a.equals(object2)
both will always return false
because a
is a string
while object2
is an instance of MyClass
I typically used docker attach to see what STDOUT was displaying, for troubleshooting containers. I just found docker logs --follow 621a4334f97b
, which lets me see the STDOUT whilst also being able to ctrl+c off of it without affecting container operation! Exactly what I've always wanted.
... naturally you'll need to substitue in your own container ID.
I wanted to leave the container running, but had attached without starting the container with -it
. My solution was to sacrifice my SSH connection instead (since I was SSHed into the machine that was running the containers). Killing that ssh session left the container intact but detached me from it.
Those variables are shell variables. To expand them as parameters to another program (ie expr
), you need to use the $
prefix:
expr $x / $y
The reason it complained is because it thought you were trying to operate on alphabetic characters (ie non-integer)
If you are using the Bash shell, you can achieve the same result using expression syntax:
echo $((x / y))
Or:
z=$((x / y))
echo $z
This might be helpful for whoever else faces this problem. I finally figured out a solution. Turns out, even if we use the inline for "content-disposition" and specify a file name, the browsers still do not use the file name. Instead browsers try and interpret the file name based on the Path/URL.
You can read further on this URL: Securly download file inside browser with correct filename
This gave me an idea, I just created my URL route that would convert the URL and end it with the name of the file I wanted to give the file. So for e.g. my original controller call just consisted of passing the Order Id of the Order being printed. I was expecting the file name to be of the format Order{0}.pdf where {0} is the Order Id. Similarly for quotes, I wanted Quote{0}.pdf.
In my controller, I just went ahead and added an additional parameter to accept the file name. I passed the filename as a parameter in the URL.Action method.
I then created a new route that would map that URL to the format: http://localhost/ShoppingCart/PrintQuote/1054/Quote1054.pdf
routes.MapRoute("", "{controller}/{action}/{orderId}/{fileName}",
new { controller = "ShoppingCart", action = "PrintQuote" }
, new string[] { "x.x.x.Controllers" }
);
This pretty much solved my issue. Hoping this helps someone!

This is extremely IMPORTANT. One of the the options i'm exploring this afternoon is using javascript callback methods rather than addEventListeners since that doesn't seem to bind correctly either. Getting all the elements ready before page load WITHOUT a page refresh is critical.
If anyone can expand upon this please do - as in, did you use a settimeout, a wait, a callback, or an addEventListener method to get the desired result. Which one and why?

From the jQuery documentation:
As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().
Try this too in addition to MahmoudS comments. Change the maven compiler source and target in your pom.xml to the java version which you are using. Say 1.7 for jdk7
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
When compiling for x64, the difference between int and long is somewhere between 0 and 4 bytes, depending on what compiler you use.
GCC uses the LP64 model, which means that ints are 32-bits but longs are 64-bits under 64-bit mode.
MSVC for example uses the LLP64 model, which means both ints and longs are 32-bits even in 64-bit mode.
If you want to achieve this selectively (ie: only to that particular link), you can use a non-breaking space instead of a normal space:
<li>submit resume</li>

I'm not very advanced in AngularJS, but my solution would be to use a simple JS class for you cart (in the sense of coffee script) that extend Array.
The beauty of AngularJS is that you can pass you "model" object with ng-click like shown below.
I don't understand the advantage of using a factory, as I find it less pretty that a CoffeeScript class.
My solution could be transformed in a Service, for reusable purpose. But otherwise I don't see any advantage of using tools like factory or service.
class Basket extends Array
constructor: ->
add: (item) ->
@push(item)
remove: (item) ->
index = @indexOf(item)
@.splice(index, 1)
contains: (item) ->
@indexOf(item) isnt -1
indexOf: (item) ->
indexOf = -1
@.forEach (stored_item, index) ->
if (item.id is stored_item.id)
indexOf = index
return indexOf
Then you initialize this in your controller and create a function for that action:
$scope.basket = new Basket()
$scope.addItemToBasket = (item) ->
$scope.basket.add(item)
Finally you set up a ng-click to an anchor, here you pass your object (retreived from the database as JSON object) to the function:
li ng-repeat="item in items"
a href="#" ng-click="addItemToBasket(item)"
This works just as well: http://jsfiddle.net/maniator/ge59E/3/
var reg = new RegExp(" ","g"); //<< just look for a space.

Function.prototype.applyAsync = function(params, cb){
var function_context = this;
setTimeout(function(){
var val = function_context.apply(undefined, params);
if(cb) cb(val);
}, 0);
}
// usage
var double = function(n){return 2*n;};
var display = function(){console.log(arguments); return undefined;};
double.applyAsync([3], display);
Although not fundamentally different than the other solutions, I think my solution does a few additional nice things:
Function.prototype
allowing a nicer way to call itAlso, the similarity to the built-in function Function.prototype.apply
seems appropriate to me.
To resolve the issue in Windows, the below steps work for me:
For example mongoDB version 3.6 is installed, and the install path of MongoDB is "D:\Program Files\MongoDB".
Create folder D:\mongodb\logs, then create file mongodb.log inside this folder.
Run cmd.exe as administrator,
D:\Program Files\MongoDB\Server\3.6\bin>taskkill /F /IM mongod.exe
D:\Program Files\MongoDB\Server\3.6\bin>mongod.exe --logpath D:\mongodb\logs\mongodb.log --logappend --dbpath D:\mongodb\data --directoryperdb --serviceName MongoDB --remove
D:\Program Files\MongoDB\Server\3.6\bin>mongod --logpath "D:\mongodb\logs\mongodb.log" --logappend --dbpath "D:\mongodb\data" --directoryperdb --serviceName "MongoDB" --serviceDisplayName "MongoDB" --install
Remove these two files mongod.lock
and storage.bson
under the folder "D:\mongodb\data".
Then type net start MongoDB
in the cmd using administrator privilege, the issue will be solved.
In Management Studio, open the Object Explorer.

If you want to retrieve the SQL statement that defines the view from T-SQL code, use this:
SELECT
m.definition
FROM sys.views v
INNER JOIN sys.sql_modules m ON m.object_id = v.object_id
WHERE name = 'Example_1'
