I used aggregate function to force paths combine as below:
public class MyPath
{
public static string ForceCombine(params string[] paths)
{
return paths.Aggregate((x, y) => Path.Combine(x, y.TrimStart('\\')));
}
}
Sometimes you need SPECIFICITY to make sure your styles are applied with strongest factor id
Thanks for @Rob Fletcher for his great answer, in our company we have used
So please consider adding styles prefixed with the id of the app container
#app input:focus::-webkit-input-placeholder, #app textarea:focus::-webkit-input-placeholder {_x000D_
color: #FFFFFF;_x000D_
}_x000D_
_x000D_
#app input:focus:-moz-placeholder, #app textarea:focus:-moz-placeholder {_x000D_
color: #FFFFFF;_x000D_
}
_x000D_
Using plain javascript
<html>
<head>
<!-- define on/off styles -->
<style type="text/css">
.on { background:blue; }
.off { background:red; }
</style>
<!-- define the toggle function -->
<script language="javascript">
function toggleState(item){
if(item.className == "on") {
item.className="off";
} else {
item.className="on";
}
}
</script>
</head>
<body>
<!-- call 'toggleState' whenever clicked -->
<input type="button" id="btn" value="button"
class="off" onclick="toggleState(this)" />
</body>
</html>
Using jQuery
If you use jQuery, you can do it using the toggle function, or using the toggleClass function inside click event handler, like this:
$(document).ready(function(){
$('a#myButton').click(function(){
$(this).toggleClass("btnClicked");
});
});
Using jQuery UI effects, you can animate transitions: http://jqueryui.com/demos/toggleClass/
Faced the same issue, another solution is to add default includes, this fixed the problem for me:
$(IncludePath);
You're trying to declare strategy
twice, and that's why you're getting the above error. The following works without any complaints (compiled with gcc -ansi -pedantic -Wall
):
#include <stdio.h>
enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;
int main(int argc, char** argv){
printf("strategy: %d\n", strategy);
return 0;
}
If instead of the above, the second line were changed to:
...
enum { RANDOM, IMMEDIATE, SEARCH } strategy;
strategy = IMMEDIATE;
...
From the warnings, you could easily see your mistake:
enums.c:5:1: warning: data definition has no type or storage class [enabled by default]
enums.c:5:1: warning: type defaults to ‘int’ in declaration of ‘strategy’ [-Wimplicit-int]
enums.c:5:1: error: conflicting types for ‘strategy’
enums.c:4:36: note: previous declaration of ‘strategy’ was here
So the compiler took strategy = IMMEDIATE
for a declaration of a variable called strategy
with default type int
, but there was already a previous declaration of a variable with this name.
However, if you placed the assignment in the main()
function, it would be a valid code:
#include <stdio.h>
enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;
int main(int argc, char** argv){
strategy=SEARCH;
printf("strategy: %d\n", strategy);
return 0;
}
dev.Dockerfile
, test.Dockerfile
, build.Dockerfile
etc.
On VS Code I use <purpose>.Dockerfile
and it gets recognized correctly.
It depends on your Linux distibution and your preference of editors etc. but I would recommend to start with Kile (a KDE app) as it is easy to learn and installing it should install most of the needed packages for LaTex and PDF generation. Just have a look at the screenshots.
This answer simply extends @Andy Hayden's, making it resilient to when numeric fields are nan
, and wrapping it up into a function.
import pandas as pd
import numpy as np
def diff_pd(df1, df2):
"""Identify differences between two pandas DataFrames"""
assert (df1.columns == df2.columns).all(), \
"DataFrame column names are different"
if any(df1.dtypes != df2.dtypes):
"Data Types are different, trying to convert"
df2 = df2.astype(df1.dtypes)
if df1.equals(df2):
return None
else:
# need to account for np.nan != np.nan returning True
diff_mask = (df1 != df2) & ~(df1.isnull() & df2.isnull())
ne_stacked = diff_mask.stack()
changed = ne_stacked[ne_stacked]
changed.index.names = ['id', 'col']
difference_locations = np.where(diff_mask)
changed_from = df1.values[difference_locations]
changed_to = df2.values[difference_locations]
return pd.DataFrame({'from': changed_from, 'to': changed_to},
index=changed.index)
So with your data (slightly edited to have a NaN in the score column):
import sys
if sys.version_info[0] < 3:
from StringIO import StringIO
else:
from io import StringIO
DF1 = StringIO("""id Name score isEnrolled Comment
111 Jack 2.17 True "He was late to class"
112 Nick 1.11 False "Graduated"
113 Zoe NaN True " "
""")
DF2 = StringIO("""id Name score isEnrolled Comment
111 Jack 2.17 True "He was late to class"
112 Nick 1.21 False "Graduated"
113 Zoe NaN False "On vacation" """)
df1 = pd.read_table(DF1, sep='\s+', index_col='id')
df2 = pd.read_table(DF2, sep='\s+', index_col='id')
diff_pd(df1, df2)
Output:
from to
id col
112 score 1.11 1.21
113 isEnrolled True False
Comment On vacation
Use this way so that result will not be displayed while running stored procedure.
The query:
SELECT a.strUserID FROM tblUsers a WHERE a.lngUserID = lngUserID LIMIT 1 INTO @strUserID;
you can use online library

or else download library and add css in css folder and jquery in js folder.both folder you keep in laravel public folder then you can link like below
<link rel="stylesheet" href="{{asset('css/bootstrap-theme.min.css')}}">

For calculating days in two dates difference, can be done like below:
import datetime
import math
issuedate = datetime(2019,5,9) #calculate the issue datetime
current_date = datetime.datetime.now() #calculate the current datetime
diff_date = current_date - issuedate #//calculate the date difference with time also
amount = fine #you want change
if diff_date.total_seconds() > 0.0: #its matching your condition
days = math.ceil(diff_date.total_seconds()/86400) #calculate days (in
one day 86400 seconds)
deductable_amount = round(amount,2)*days #calclulated fine for all days
Becuase if one second is more with the due date then we have to charge
SELECT * FROM tablename WHERE visible=1 ORDER BY CASE WHEN `position` = 0 THEN 'a' END , position ASC
To dynamically change the color of a text box goto properties, goto font/Color and set the following expression
=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)
Same way for tolerance
=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

I used @Joy's awesome answer, and it worked perfectly with ios 8.4 and XCode 7.1.1.
In case you are looking to make your cell toggle-able, I changed the -tableViewDidSelect to the following:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//This is the bit I changed, so that if tapped once on the cell,
//cell is expanded. If tapped again on the same cell,
//cell is collapsed.
if (self.currentSelection==indexPath.row) {
self.currentSelection = -1;
}else{
self.currentSelection = indexPath.row;
}
// animate
[tableView beginUpdates];
[tableView endUpdates];
}
I hope any of this helped you.
As commented, just in case the link I posted there broke, try this:
Add a Name(any valid name) in Excel's Name Manager under Formula tab in the Ribbon.
Then assign a formula using GET.CELL function.
=GET.CELL(63,INDIRECT("rc",FALSE))
63 stands for backcolor.
Let's say we name it Background so in any cell with color type:
=Background
Result:
Notice that Cells A2, A3 and A4 returns 3, 4, and 5 respectively which equates to the cells background color index. HTH.
BTW, here's a link on Excel's Color Index
You always have to set the width and height of an Image
. It is not going to automatically size things for you. The React Native docs says so.
You should measure the total height of the ScrollView
using onLayout
and set the height of the Image
s based on it. If you use resizeMode
of cover
it will keep the aspect ratio of your Image
s but it will obviously crop them if it's bigger than the container.
I encountered this in a unique situation: had refactored the word "time" to "distance" for one of my variables. And when I did the refactor, accidentally had it change the name of one of my gradle dependencies / implementations.
This is a rare cause of the error, but a possibility. So make sure all your dependencies are properly implemented in build.gradle
I'll just update the code to contain the changes, and comment it to so that you can see what's going on clearly...
<?php
include("templates/header.htm");
// Set the default name
$action = 'index';
// Specify some disallowed paths
$disallowed_paths = array('header', 'footer');
if (!empty($_GET['action'])) {
$tmp_action = basename($_GET['action']);
// If it's not a disallowed path, and if the file exists, update $action
if (!in_array($tmp_action, $disallowed_paths) && file_exists("templates/{$tmp_action}.htm"))
$action = $tmp_action;
}
// Include $action
include("templates/$action.htm");
include("templates/footer.htm");
The marked answer seems outdated and it won't work.
Facebook now only gives unique ID related to app which isn't equal to userId and profileUrl and username will come out to be empty.
Doing me?fields=id,name,links
is also depreciated after Graph Version 2.4
The only option now is to request for user_links permission from your developer console.
and the pass it in scope when doing facebook login
scope: ['user_link'] }
or by doing an api call
If it's not a big/long array just mirror it:
for( int i = 0; i < arr.length/2; ++i )
{
temp = arr[i];
arr[i] = arr[arr.length - i - 1];
arr[arr.length - i - 1] = temp;
}
First up, going by the function name xssRequest it sounds like you're trying cross site request - which if that's right, you're not going to be able to read the contents of the iframe.
On the other hand, if the iframe's URL is on your domain you can access the body, but I've found that if I use a timeout to remove the iframe the callback works fine:
// possibly excessive use of jQuery - but I've got a live working example in production
$('#myUniqueID').load(function () {
if (typeof callback == 'function') {
callback($('body', this.contentWindow.document).html());
}
setTimeout(function () {$('#frameId').remove();}, 50);
});
You can use this:
SELECT COUNT(*) FROM (SELECT DISTINCT column_name FROM table_name) AS temp;
This is much faster than:
COUNT(DISTINCT column_name)
Great answer Alex. One potential issue is the NULL dereference. Apple's reference on Creating and Returning NSError objects
...
[details setValue:@"ran out of money" forKey:NSLocalizedDescriptionKey];
if (error != NULL) {
// populate the error object with the details
*error = [NSError errorWithDomain:@"world" code:200 userInfo:details];
}
// we couldn't feed the world's children...return nil..sniffle...sniffle
return nil;
...
I've personally never found it useful to set M2_HOME
.
What counts is your $PATH environment. Hijacking part of the answer from Danix, all you need is:
export PATH=/Users/xxx/sdk/apache-maven-3.0.5/bin:$PATH
The mvn
script computes M2_HOME
for you anyway for what it's worth.
If you have your CSS in the internal file storage you can use
//Get a reference to your webview
WebView web = (WebView)findViewById(R.id.webby);
// Prepare some html, it is formated with css loaded from the file style.css
String webContent = "<!DOCTYPE html><html><head><meta charset=\"UTF-8\"><link rel=\"stylesheet\" href=\"style.css\"></head>"
+ "<body><div class=\"running\">I am a text rendered with INDIGO</div></body></html>";
//get and format the path pointing to the internal storage
String internalFilePath = "file://" + getFilesDir().getAbsolutePath() + "/";
//load the html with the baseURL, all files relative to the baseURL will be found
web.loadDataWithBaseURL(internalFilePath, webContent, "text/html", "UTF-8", "");
To replace all content matching string_1 with string_2 of all .c and .h files in the current directory and subdirectories (excluding .git/).
This works on Mac:
find . -type f -path "*.git*" -prune -o -name '*\.[ch]' -exec \
sed -i '' -e 's/'$1'/'$2'/g' {} +
This should work on Linux (Have not tested yet):
find . -type f -path "*.git*" -prune -o -name '*\.[ch]' -exec \
sed -i 's/string_1/string_2/g' {} +
I was having 2 values which could contain null values.

I found the best and easiest way to do it is this one because you don't need to add labels, divs or whatsoever.
input { vertical-align: middle; margin-top: -1px;}
I somehow found this to be neater than using the StringBuilder/StringBuffer approach.
I guess it depends on what approach you took.
The AbstractCollection#toString() method simply iterates over all the elements and appends them to a StringBuilder. So your method may be saving a few lines of code but at the cost of extra String manipulation. Whether that tradeoff is a good one is up to you.
Displays a list of files and subdirectories in a directory.

[/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]
[drive:][path][filename]
Specifies drive, directory, and/or files to list.
/A Displays files with specified attributes.
attributes D Directories R Read-only files
H Hidden files A Files ready for archiving
S System files I Not content indexed files
L Reparse Points - Prefix meaning not
just set type of desired file attribute, in your case /A:D (directory)
dir /s/b/o:n/A:D > f.txt

This works for me, and in this case was a remote connection: Note: The port was IMPORTANT for me
$dsn = "sqlsrv:Server=server.dyndns.biz,1433;Database=DBNAME";
$conn = new PDO($dsn, "root", "P4sw0rd");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$sql = "SELECT * FROM Table";
foreach ($conn->query($sql) as $row) {
print_r($row);
}
You can do a reverse DNS lookup with host
, too. Just give it the IP address as an argument:
$ host 192.168.0.10
server10 has address 192.168.0.10
var p=document.getElementById('childId').parentNode;
var c=document.getElementById('childId');
p.removeChild(c);
alert('Deleted');
p is parent node and c is child node
parentNode is a JavaScript variable which contains parent reference
Easy to understand
What you're doing there is not recursing into directories. It is only listing the modules in the root directory of the @INC
directory.
The module XML::Simple
will live in one of the @INC
paths under XML/Simple.pm
.
What he said above to find specific modules.
CPAN
explains how to find all modules here, see How to find installed modules.
Following worked for me:
CSS
.round {
border-radius: 50%;
overflow: hidden;
width: 30px;
height: 30px;
background: no-repeat 50%;
object-fit: cover;
}
.round img {
display: block;
height: 100%;
width: 100%;
}
HTML
<div class="round">
<img src="test.png" />
</div>

In case anyone was still looking and came across this SO post like I did.
<input type="submit" name="open" value="Open">
<input type="submit" name="close" value="Close">
def contact():
if "open" in request.form:
pass
elif "close" in request.form:
pass
return render_template('contact.html')
Simple, concise, and it works. Don't even need to instantiate a form object.
Try this:
<table width="200" style="margin-left:auto;margin-right:auto">
If your selected elements are not one, you need use this way:
$('[type="date"]').datepicker();
$('[type="date"]').change(function() {
var date = $(this).datepicker("getDate");
console.log(date);
});
Session in Asp.net:
1.Maintains the data accross all over the application.
2.Persists the data if current session is alive. If we need some data to accessible from multiple controllers acitons and views the session is the way to store and retreive data.
3.Sessions are server side files that contains user information. [Sessions are unique identifier that maps them to specific users]
Translating that to Web Servers: The server will store the pertinent information in the session object, and create a session ID which it will send back to the client in a cookie. When the client sends back the cookie, the server can simply look up the session object using the ID. So, if you delete the cookie, the session will be lost.
I have faced this particular error when I didn't defined the main() function. Check if the main() function exists or check the name of the function letter by letter as Timothy described above or check if the file where the main function is located is included to your project.
I tried above answers and it didn't work in my project. My project was with maven
and openjfx
in Windows.
This solved the problem :
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("/main.fxml"));
root = fxmlLoader.load()
If you have rooted your phone, but so not have busybox, only stock toybox, here a one-liner to run as root :
mount -o rw,remount $( mount | sed '/ /system /!d' | cut -d " " -f 1 ) /system
toybox do not support the "-o remount,rw" option
if you have busybox, you can use it :
busybox mount -o remount,rw /system
I had the same problem.
Here is a workaround
android:inputType="textNoSuggestions|textVisiblePassword"
android:maxLength="6"
Simple method:
public boolean isBlank(String value) {
return (value == null || value.equals("") || value.equals("null") || value.trim().equals(""));
}
public boolean isOnlyNumber(String value) {
boolean ret = false;
if (!isBlank(value)) {
ret = value.matches("^[0-9]+$");
}
return ret;
}
I've read many of the answers and made my own. Not sure this one will fix in any case, but it fixes in my environment. I'm just not using WaitForExit and use WaitHandle.WaitAll on both output & error end signals. I will be glad, if someone will see possible problems with that. Or if it will help someone. For me it's better because not uses timeouts.

This is what I needed:

CharBuffer data = sourceCharset.decode(inputBuffer);
ByteBuffer outputBuffer = targetCharset.encode(data);
byte[] outputData = outputBuffer.array();
return outputData;

I would like to share Kotlin Answer :
fun setTextColor(tv:TextView, startPosition:Int, endPosition:Int, color:Int){
val spannableStr = SpannableString(tv.text)
val underlineSpan = UnderlineSpan()
spannableStr.setSpan(
underlineSpan,
startPosition,
endPosition,
Spanned.SPAN_INCLUSIVE_EXCLUSIVE
)
val backgroundColorSpan = ForegroundColorSpan(this.resources.getColor(R.color.agreement_color))
spannableStr.setSpan(
backgroundColorSpan,
startPosition,
endPosition,
Spanned.SPAN_INCLUSIVE_EXCLUSIVE
)
val styleSpanItalic = StyleSpan(Typeface.BOLD)
spannableStr.setSpan(
styleSpanItalic,
startPosition,
endPosition,
Spanned.SPAN_INCLUSIVE_EXCLUSIVE
)
tv.text = spannableStr
}
After, call above function. You can call more than one:
setTextColor(textView, 0, 61, R.color.agreement_color)
setTextColor(textView, 65, 75, R.color.colorPrimary)
Output: You can see underline and different colors with each other.

You can use http://www.fontsquirrel.com/fontface/generator to encode any font for websites. It'll generate the code to include the font.
I don't really use it for fonts over 30px. They look much better as an image (because images are anti-aliased, and some browsers don't anti-alias fonts in the browser).
See: http://www.truetype-typography.com/ttalias.htm
Hope that helps...
By alphabetical-order I assume the order to be : A|a < B|b < C|c... Hope this is what @Nick is(or was) looking for and the answer follows the above assumption.
I would suggest to have a class implement compare method of Comparator-interface as :
public int compare(Object o1, Object o2) {
return o1.toString().compareToIgnoreCase(o2.toString());
}
and from the calling method invoke the Arrays.sort method with custom Comparator as :
Arrays.sort(inputArray, customComparator);
Observed results: input Array : "Vani","Kali", "Mohan","Soni","kuldeep","Arun"
output(Alphabetical-order) is : Arun, Kali, kuldeep, Mohan, Soni, Vani
Output(Natural-order by executing Arrays.sort(inputArray) is : Arun, Kali, Mohan, Soni, Vani, kuldeep
Thus in case of natural ordering, [Vani < kuldeep] which to my understanding of alphabetical-order is not the thing desired.
for more understanding of natural and alphabetical/lexical order visit discussion here

Are you looking for the root folder of the application? Then I would use
String path = getClass().getClassLoader().getResource(".").getPath();
to actually "find out where I am".
The default colours in Gecko, assuming the user hasn't changed their preferences, are:
#0000EE
(blue)#551A8B
(purple)#EE0000
(red)Gecko also provides names for the user's colours; they are -moz-hyperlinktext
-moz-visitedhyperlinktext
and -moz-activehyperlinktext
and they also provide -moz-nativehyperlinktext
which is the system link colour.
With locales :
var date = new Date();
date.toLocaleTimeString('fr-FR', {hour: '2-digit', minute: '2-digit'})
it's because some of the fields (specifically InvoiceID on the Invoices table and on the InvoiceLineItems) are present on both table. The way to answer of question is to add an ALIAS
on it.
SELECT
a.VendorName, Invoices.InvoiceID, .. -- or use full tableName
FROM Vendors a -- This is an `ALIAS` of table Vendors
JOIN Invoices ON (Vendors.VendorID = Invoices.VendorID)
JOIN InvoiceLineItems ON (Invoices.InvoiceID = InvoiceLineItems.InvoiceID)
WHERE
Invoices.InvoiceID IN
(SELECT InvoiceSequence
FROM InvoiceLineItems
WHERE InvoiceSequence > 1)
ORDER BY
VendorName, InvoiceID, InvoiceSequence, InvoiceLineItemAmount
gem update --system
will update the rubygems and will fix the problem.
I had the same problem when I submitted data using jQuery AJAX:
$.ajax({
url:...
success:function(data){
//server response's data is JSON
//I use jQuery's parseJSON method
$.parseJSON(data);//it's ERROR
}
});
If the response is JSON, and you use this method, the data you get is a JavaScript object, but if you use dataType:"text"
, data is a JSON string. Then the use of $.parseJSON
is okay.
I know it's a relative old post but, I would like to share what worked for me: I've simply input "http://" before "localhost" in the url. Hope it helps somebody.
You need to wrap button click handler to match the pattern
public void klik(object sender, EventArgs e)
SELECT * FROM table
ORDER BY NEWID()
The last-child
selector is used to select the last child element of a parent. It cannot be used to select the last child element with a specific class under a given parent element.
The other part of the compound selector (which is attached before the :last-child
) specifies extra conditions which the last child element must satisfy in-order for it to be selected. In the below snippet, you would see how the selected elements differ depending on the rest of the compound selector.
.parent :last-child{ /* this will select all elements which are last child of .parent */_x000D_
font-weight: bold;_x000D_
}_x000D_
_x000D_
.parent div:last-child{ /* this will select the last child of .parent only if it is a div*/_x000D_

To answer your question, the below would style the last child li
element with background color as red.
li:last-child{
background-color: red;
}
But the following selector would not work for your markup because the last-child
does not have the class='complete'
even though it is an li
.
li.complete:last-child{
background-color: green;
}
It would have worked if (and only if) the last li
in your markup also had class='complete'
.
To address your query in the comments:
@Harry I find it rather odd that: .complete:last-of-type does not work, yet .complete:first-of-type does work, regardless of it's position it's parents element. Thanks for your help.
The selector .complete:first-of-type
works in the fiddle because it (that is, the element with class='complete'
) is still the first element of type li
within the parent. Try to add <li>0</li>
as the first element under the ul
and you will find that first-of-type
also flops. This is because the first-of-type
and last-of-type
selectors select the first/last element of each type under the parent.
Refer to the answer posted by BoltClock, in this thread for more details about how the selector works. That is as comprehensive as it gets :)
2015 answer: we have this out of the box on modern browsers, just use the HTML5 CheckValidity API from jQuery. I've also made a jquery-html5-validity module to do this:
npm install jquery-html5-validity
Then:
var $ = require('jquery')
require("jquery-html5-validity")($);
then you can run:
$('.some-class').isValid()
true
You can use this function
var datastring = $("#contactForm").serialize();
$.ajax({
type: "POST",
url: "your url.php",
data: datastring,
dataType: "json",
success: function(data) {
//var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
// do what ever you want with the server response
},
error: function() {
alert('error handling here');
}
});
return type is json
EDIT: I use event.preventDefault
to prevent the browser getting submitted in such scenarios.
Adding more data to the answer.
dataType: "jsonp"
if it is a cross-domain call.
beforeSend:
// this is a pre-request call back function
complete:
// a function to be called after the request ends.so code that has to be executed regardless of success or error can go here
async:
// by default, all requests are sent asynchronously
cache:
// by default true. If set to false, it will force requested pages not to be cached by the browser.

above solution doesn't work for me for unknown reason. below is my workaround which was worked successfully.
1) DO NOT generate a new ssh key by using command ssh-keygen -t rsa -C"[email protected]"
, you can delete existing SSH keys.
2) but use Git GUI, -> "Help" -> "Show ssh key" -> "Generate key", the key will saved to ssh automatically and no need to use ssh-add
anymore.
alert('Alert For your User!') ? "" : location.reload();
You can write above code in this format also.It seems quite decent
You can invoke private method with reflection. Modifying the last bit of the posted code:
Method method = object.getClass().getDeclaredMethod(methodName);
method.setAccessible(true);
Object r = method.invoke(object);
There are a couple of caveats. First, getDeclaredMethod
will only find method declared in the current Class
, not inherited from supertypes. So, traverse up the concrete class hierarchy if necessary. Second, a SecurityManager
can prevent use of the setAccessible
method. So, it may need to run as a PrivilegedAction
(using AccessController
or Subject
).

The easiest solution I found is to just rename the php folder version as such:
That way only two of them will be read by MAMP. Done!
I've added the Initial Catalog to your connection string. I've also abandonded the ADODB.Command syntax in favor of simply creating my own SQL statement and open the recordset on that variable.
Hope this helps.
Sub GetDataFromADO()
'Declare variables'
Set objMyConn = New ADODB.Connection
Set objMyRecordset = New ADODB.Recordset
Dim strSQL As String
'Open Connection'
objMyConn.ConnectionString = "Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=MyDatabase;User ID=abc;Password=abc;"
objMyConn.Open
'Set and Excecute SQL Command'
strSQL = "select * from myTable"
'Open Recordset'
Set objMyRecordset.ActiveConnection = objMyConn
objMyRecordset.Open strSQL
'Copy Data to Excel'
ActiveSheet.Range("A1").CopyFromRecordset (objMyRecordset)
End Sub
Ack! Constant strings:
const char *strings[] = {"one","two","three"};
If I remember correctly.
Oh, and you want to use strcpy for assignment, not the = operator. strcpy_s is safer, but it's neither in C89 nor in C99 standards.
char arr[MAX_NUMBER_STRINGS][MAX_STRING_SIZE];
strcpy(arr[0], "blah");
Update: Thomas says strlcpy
is the way to go.
Just set preventDefault and return false
$('#your-identifier').click(function(e) {
e.preventDefault();
return false;
});
This will be disabled link but still, you will see a clickable icon(hand) icon. You can remove that too with below
$('#your-identifier').css('cursor', 'auto');
A simple explanation is: A framework is a scaffold that you can you build applications around.
A framework generally provides some base functionality which you can use and extend to make more complex applications from, there are frameworks for all sorts of things. Microsofts MVC framework is a good example of this. It provides everything you need to get off the ground building website using the MVC pattern, it handles web requests, routes and the like. All you have to do is implement "Controllers" and provide "Views" which are two constructs defined by the MVC framework. The MVC framework then handles calling your controllers and rendering your views.
Perhaps not the best wording but I hope it helps
Simple and Best option retrieve the content mime type from the file location.
Use this imports
import java.nio.file.Files;
import java.nio.file.Path;
Code
String type = Files.probeContentType(Path.of(imagePath));
The Code is very Simple, Lets Put This Code
var name = $("#band_type_choices option:selected").text();
Here You don't want to use $(this).find().text()
, directly you can put your id name and add
option:selected
along with text()
.
This will return the result option name. Better Try this...
<asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID" Display="Dynamic"
ValidationGroup="g1" runat="server" ControlToValidate="ControlID"
Text="*" ErrorMessage="ErrorMessage"></asp:RequiredFieldValidator>
If you are using moment.js you can do it easily.
var start = moment("2018-03-10", "YYYY-MM-DD");
var end = moment("2018-03-15", "YYYY-MM-DD");
//Difference in number of days
moment.duration(start.diff(end)).asDays();
//Difference in number of weeks
moment.duration(start.diff(end)).asWeeks();
If you want to find difference between a given date and current date in number of days (ignoring time), make sure to remove time from moment object of current date as below
moment().startOf('day')
To find difference between a given date and current date in number of days
var given = moment("2018-03-10", "YYYY-MM-DD");
var current = moment().startOf('day');
//Difference in number of days
moment.duration(given.diff(current)).asDays();
Ok after doing reverse engineering and a little pixie dust of reflection, one can do this operation on SelectedCells
(at any point) to get all (regardless of selected on one row or many rows) the data from one to many selected cells:
MessageBox.Show(
string.Join(", ", myGrid.SelectedCells
.Select(cl => cl.Item.GetType()
.GetProperty(cl.Column.SortMemberPath)
.GetValue(cl.Item, null)))
);
I tried this on text (string) fields only though a DateTime field should return a value the initiate ToString()
. Also note that SortMemberPath
is not the same as Header
so that should always provide the proper property to reflect off of.
<DataGrid ItemsSource="{Binding MyData}"
AutoGenerateColumns="True"
Name="myGrid"
IsReadOnly="True"
SelectionUnit="Cell"
SelectionMode="Extended">
The OP added in his question:
the files checked out using msysgit are using
CR+LF
and I want to force msysgit to get them withLF
A first simple step would still be in a .gitattributes
file:
# 2010
*.txt -crlf
# 2020
*.txt text eol=lf
(as noted in the comments by grandchild, referring to .gitattributes
End-of-line conversion), to avoid any CRLF
conversion for files with correct eol
.
And I have always recommended git config --global core.autocrlf false
to disable any conversion (which would apply to all versioned files)
See Best practices for cross platform git config?
Since Git 2.16 (Q1 2018), you can use git add --renormalize .
to apply those .gitattributes
settings immediately.
But a second more powerful step involves a gitattribute filter driver and add a smudge step
Whenever you would update your working tree, a script could, only for the files you have specified in the .gitattributes
, force the LF eol
and any other formatting option you want to enforce.
If the "clear
" script doesn't do anything, you will have (after commit) transformed your files, applying exactly the format you need them to follow.
in the search window type 'environment variables' this should give you a link to editing the variables. On the variables editing page there is an upper section and a lower section in the lower section add NEW,type path C:\Program Files\Java\jdk-10\bin this worked great for me and it finds the compiler all the time.
ApplicationContextAware Interface ,the current application context, through which you can invoke the spring container services. We can get current applicationContext instance injected by below method in the class

The xargs
command takes white space characters (tabs, spaces, new lines) as delimiters.
You can narrow it down only for the new line characters ('\n') with -d
option like this:
ls *.mp3 | xargs -d '\n' mplayer
It works only with GNU xargs.
For BSD systems, use the -0
option like this:
ls *.mp3 | xargs -0 mplayer
This method is simpler and works with the GNU xargs as well.
For MacOS:
ls *.mp3 | tr \\n \\0 | xargs -0 mplayer
If you want to write it to disk so that it will be easy to read back in as a numpy array, look into numpy.save
. Pickling it will work fine, as well, but it's less efficient for large arrays (which yours isn't, so either is perfectly fine).
If you want it to be human readable, look into numpy.savetxt
.
Edit: So, it seems like savetxt
isn't quite as great an option for arrays with >2 dimensions... But just to draw everything out to it's full conclusion:
I just realized that numpy.savetxt
chokes on ndarrays with more than 2 dimensions... This is probably by design, as there's no inherently defined way to indicate additional dimensions in a text file.
E.g. This (a 2D array) works fine
import numpy as np
x = np.arange(20).reshape((4,5))
np.savetxt('test.txt', x)
While the same thing would fail (with a rather uninformative error: TypeError: float argument required, not numpy.ndarray
) for a 3D array:
import numpy as np
x = np.arange(200).reshape((4,5,10))
np.savetxt('test.txt', x)
One workaround is just to break the 3D (or greater) array into 2D slices. E.g.
x = np.arange(200).reshape((4,5,10))
with open('test.txt', 'w') as outfile:
for slice_2d in x:
np.savetxt(outfile, slice_2d)
However, our goal is to be clearly human readable, while still being easily read back in with numpy.loadtxt
. Therefore, we can be a bit more verbose, and differentiate the slices using commented out lines. By default, numpy.loadtxt
will ignore any lines that start with #
(or whichever character is specified by the comments
kwarg). (This looks more verbose than it actually is...)
import numpy as np
# Generate some test data
data = np.arange(200).reshape((4,5,10))
# Write the array to disk
with open('test.txt', 'w') as outfile:
# I'm writing a header here just for the sake of readability
# Any line starting with "#" will be ignored by numpy.loadtxt
outfile.write('# Array shape: {0}\n'.format(data.shape))
# Iterating through a ndimensional array produces slices along
# the last axis. This is equivalent to data[i,:,:] in this case
for data_slice in data:
# The formatting string indicates that I'm writing out
# the values in left-justified columns 7 characters in width
# with 2 decimal places.
np.savetxt(outfile, data_slice, fmt='%-7.2f')
# Writing out a break to indicate different slices...
outfile.write('# New slice\n')
This yields:
# Array shape: (4, 5, 10)

Reading it back in is very easy, as long as we know the shape of the original array. We can just do numpy.loadtxt('test.txt').reshape((4,5,10))
. As an example (You can do this in one line, I'm just being verbose to clarify things):
# Read the array from disk
new_data = np.loadtxt('test.txt')
# Note that this returned a 2D array!
print new_data.shape
# However, going back to 3D is easy if we know the
# original shape of the array
new_data = new_data.reshape((4,5,10))
# Just to check that they're the same...
assert np.all(new_data == data)
Well this work for me. First in AppDelegate
import UserNotifications
Then:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
registerForRemoteNotification()
return true
}
func registerForRemoteNotification() {
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
if error == nil{
UIApplication.shared.registerForRemoteNotifications()
}
}
}
else {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
}
To get devicetoken:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
}
If you are trying to make more than just one folder on the root of the sdcard,

you would use folder.mkdirs()
I've made this mistake in the past & I took forever to figure it out.
I work on 60-70% zoom vue and my dropdown are unreadable so I made this simple code to overcome the issue
Note that I selected first all my dropdown lsts (CTRL+mouse click), went on formula tab, clicked "define name" and called them "ProduktSelection"
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim KeyCells As Range
Set KeyCells = Range("ProduktSelection")
If Not Application.Intersect(KeyCells, Range(Target.Address)) _
Is Nothing Then
ActiveWindow.Zoom = 100
End If
End Sub
I then have another sub
Private Sub Worksheet_Change(ByVal Target As Range)
where I come back to 65% when value is changed.

I came across another solution here that is so simple: add padding-right to the textarea's container. This keeps the margin, border, and padding on the textarea, which avoids the problem that Beck pointed out about the focus highlight that chrome and safari put around the textarea.
The container's padding-right should be the sum of the effective margin, border, and padding on both sides of the textarea, plus any padding you may otherwise want for the container. So, for the case in the original question:
textarea{
border:1px solid #999999;
width:100%;
margin:5px 0;
padding:3px;
}
.textareacontainer{
padding-right: 8px; /* 1 + 3 + 3 + 1 */
}

Here's how to fix this error when launching Eclipse:
Version 1.6.0_65 of the JVM is not suitable for this product. Version: 1.7 or greater is required.
Go and install latest JDK
Make sure you have installed 64 bit Eclipse
The easiest way is probably to use two parameters: One for hosts (can be an array), and one for vlan.
param([String[]] $Hosts, [String] $VLAN)
Instead of
foreach ($i in $args)
you can use
foreach ($hostName in $Hosts)
If there is only one host, the foreach loop will iterate only once. To pass multiple hosts to the script, pass it as an array:
myScript.ps1 -Hosts host1,host2,host3 -VLAN 2
...or something similar.
ul {_x000D_
display: table;_x000D_
margin: 0 auto;_x000D_

Some of the other answers here inspired me to write a script for automating the mixed sequential execution of SQL tasks using SQLPLUS along with shell commands for a project, a process that was previously manually done. Maybe this (highly sanitized) example will be useful to someone else:
#!/bin/bash
acreds="user_a/supergreatpassword"
bcreds="user_b/anothergreatpassword"
hoststring='fancyoraclehoststring'
runsql () {
# param 1 is $1
sqlplus -S /nolog << EOF
CONNECT $1@$hoststring;
whenever sqlerror exit sql.sqlcode;
set echo off
set heading off
$2
exit;
EOF
}
echo "TS::$(date): Starting SCHEM_A.PROC_YOU_NEED()..."
runsql "$acreds" "execute SCHEM_A.PROC_YOU_NEED();"
echo "TS::$(date): Starting superusefuljob..."
/var/scripts/superusefuljob.sh
echo "TS::$(date): Starting SCHEM_B.SECRET_B_PROC()..."
runsql "$bcreds" "execute SCHEM_B.SECRET_B_PROC();"
echo "TS::$(date): DONE"
runsql
allows you to pass a credential string as the first argument, and any SQL you need as the second argument. The variables containing the credentials are included for illustration, but for security I actually source them from another file. If you wanted to handle multiple database connections, you could easily modify the function to accept the hoststring as an additional parameter.
Either !=
or ne
will work, but you need to get the accessor syntax and nested quotes sorted out.
<c:if test="${content.contentType.name ne 'MCE'}">
<%-- snip --%>
</c:if>
You can do it like the other people before me told you using a look:
A.) Use .data of the button element to share a look variable (or a just global variable)
if ($('#buttonId').data('locked') == 1)
return
$('#buttonId').data('locked') = 1;
// Do your thing
$('#buttonId').data('locked') = 0;
B.) Disable mouse signals
$("#buttonId").css("pointer-events", "none");
// Do your thing
$("#buttonId").css("pointer-events", "auto");
C.) If it is a HTML button you can disable it (input [type=submit] or button)
$("#buttonId").attr("disabled", "true");
// Do your thing
$("#buttonId").attr("disabled", "false");
But watch out for other threads! I failed many times because my animation (fading in or out) took one second.
E.g. fadeIn/fadeOut supports a callback function as second parameter.
If there is no other way just do it using setTimeout(callback, delay)
.
Greets, Thomas
With chrome, if you surround an input with a label and within the label, put the words street, address or both, it will ignore any attempt at disabling autofill.
<label for="searchAddress" class="control-label"> Street Address <input type="text" class="form-control" name="searchAddress></label>
Chrome detects keywords within the label to figure out the input type. It likely does this with other key words as well.
You can also just clone the repo, after cloning is done, just pick the folder or vile that you want. To clone:
git clone https://github.com/somegithubuser/somgithubrepo.git
then go to the cloned DIR and find your file or DIR you want to copy.
In Laravel 5.1 and later you can use
request()->getHost();
or
request()->getHttpHost();
(the second one will add port if it's not standard one)
In HTML:
<input type="submit" onclick="return false">
With jQuery, some similar variant, already mentioned.
The posts here help me a lot on my way to find a solution for the Uncaught TypeError: Cannot read property 'value' of undefined issue.
There are already here many answers which are correct, but what we don't have here is the combination for 2 answers that i think resolve this issue completely.
function myFunction(field, data){
if (typeof document.getElementsByName("+field+")[0] != 'undefined'){
document.getElementsByName("+field+")[0].value=data;
}
}
The difference is that you make a check(if a property is defined or not) and if the check is true then you can try to assign it a value.
You could opt for Views as shown below:
CREATE VIEW AuthorizedUserProjectView AS select t1.username as username, t1.email as useremail, p.id as projectid,
(select m.role from userproject m where m.projectid = p.id and m.userid = t1.id) as role
FROM authorizeduser as t1, project as p
and then work on the view for selecting or updating:
select * from AuthorizedUserProjectView where projectid = 49
which yields the result as shown in the picture below i.e. for non-matching column null has been filled in.
[Result of select on the view][1]
Basically it checks if the value before the || evaluates to true, if yes, it takes this value, if not, it takes the value after the ||.
Values for which it will take the value after the || (as far as i remember):
Here are my 2 cents = 5 methods ;)

Technically in C++, the strict aliasing rule is probably never applicable.
Note the definition of indirection (* operator):
The unary * operator performs indirection: the expression to which it is applied shall be a pointer to an object type, or a pointer to a function type and the result is an lvalue referring to the object or function to which the expression points.
Also from the definition of glvalue
A glvalue is an expression whose evaluation determines the identity of an object, (...snip)
So in any well defined program trace, a glvalue refers to an object. So the so called strict aliasing rule doesn't apply, ever. This may not be what the designers wanted.
Tumblr has a public API that provides JSON. You can get a dump of posts using a simple url like http://puppygifs.tumblr.com/api/read/json

You could do it yourself (thats what I did) - in order to not be bothered with exception handling, you simply extend the RuntimeException, your class could look something like this:
public class NotImplementedException extends RuntimeException {
private static final long serialVersionUID = 1L;
public NotImplementedException(){}
}
You could extend it to take a message - but if you use the method as I do (that is, as a reminder, that there is still something to be implemented), then usually there is no need for additional messages.
I dare say, that I only use this method, while I am in the process of developing a system, makes it easier for me to not lose track of which methods are still not implemented properly :)
With RxJS
:
import { timer } from 'rxjs';
// ...
timer(your_delay_in_ms).subscribe(x => { your_action_code_here })
x
is 0.
If you give a second argument period
to timer
, a new number will be emitted each period
milliseconds (x = 0 then x = 1, x = 2, ...).
See the official doc for more details.
Try this:
select nextval('my_seq_name'); // Returns next value
If this return 1 (or whatever is the start_value for your sequence), then reset the sequence back to the original value, passing the false flag:
select setval('my_seq_name', 1, false);
Otherwise,
select setval('my_seq_name', nextValue - 1, true);
This will restore the sequence value to the original state and "setval" will return with the sequence value you are looking for.
The most important difference is that gzip is only capable to compress a single file while zip compresses multiple files one by one and archives them into one single file afterwards. Thus, gzip comes along with tar most of the time (there are other possibilities, though). This comes along with some (dis)advantages.
If you have a big archive and you only need one single file out of it, you have to decompress the whole gzip file to get to that file. This is not required if you have a zip file.
On the other hand, if you compress 10 similiar or even identical files, the zip archive will be much bigger because each file is compressed individually, whereas in gzip in combination with tar a single file is compressed which is much more effective if the files are similiar (equal).

$( "#slider-range" ).slider("refresh");
I added this on my project and it seems to work:
HTMLElement.prototype.prependHtml = function (element) {

HTMLElement.prototype.appendHtml = function (element) {
const div = document.createElement('div');
div.innerHTML = element;
while (div.children.length > 0) {
this.appendChild(div.children[0]);
}
};
Example:
document.body.prependHtml(`<a href="#">Hello World</a>`);
document.body.appendHtml(`<a href="#">Hello World</a>`);
use &

change to

HTML Table row heights will typically change proportionally to the table height, if the table height is larger than the height of your rows. Since the table is forcing the height of your rows, you can remove the table height to resolve the issue. If this is not acceptable, you can also give the rows explicit height, and add a third row that will auto size to the remaining table height.
Another option in CSS2 is the Max-Height Property, although it may lead to strange behavior in a table.http://www.w3schools.com/cssref/pr_dim_max-height.asp

In computing, the 'kernel' is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components). Usually as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources (especially processors and I/O devices) that application software must control to perform its function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.

We can use git mv command. Example below , if we renamed file abcDEF.js to abcdef.js then we can run the following command from terminal
git mv -f .\abcDEF.js .\abcdef.js
A sample command that exhibits the symptom: sed 's/./@/' <<<$'\xfc'
fails, because byte 0xfc
is not a valid UTF-8 char.
Note that, by contrast, GNU sed
(Linux, but also installable on macOS) simply passes the invalid byte through, without reporting an error.
Using the formerly accepted answer is an option if you don't mind losing support for your true locale (if you're on a US system and you never need to deal with foreign characters, that may be fine.)
However, the same effect can be had ad-hoc for a single command only:
LC_ALL=C sed -i "" 's|"iphoneos-cross","llvm-gcc:-O3|"iphoneos-cross","clang:-Os|g' Configure
Note: What matters is an effective LC_CTYPE
setting of C
, so LC_CTYPE=C sed ...
would normally also work, but if LC_ALL
happens to be set (to something other than C
), it will override individual LC_*
-category variables such as LC_CTYPE
. Thus, the most robust approach is to set LC_ALL
.
However, (effectively) setting LC_CTYPE
to C
treats strings as if each byte were its own character (no interpretation based on encoding rules is performed), with no regard for the - multibyte-on-demand - UTF-8 encoding that OS X employs by default, where foreign characters have multibyte encodings.
In a nutshell: setting LC_CTYPE
to C
causes the shell and utilities to only recognize basic English letters as letters (the ones in the 7-bit ASCII range), so that foreign chars. will not be treated as letters, causing, for instance, upper-/lowercase conversions to fail.
Again, this may be fine if you needn't match multibyte-encoded characters such as é
, and simply want to pass such characters through.
If this is insufficient and/or you want to understand the cause of the original error (including determining what input bytes caused the problem) and perform encoding conversions on demand, read on below.
The problem is that the input file's encoding does not match the shell's.
More specifically, the input file contains characters encoded in a way that is not valid in UTF-8 (as @Klas Lindbäck stated in a comment) - that's what the sed
error message is trying to say by invalid byte sequence
.
Most likely, your input file uses a single-byte 8-bit encoding such as ISO-8859-1
, frequently used to encode "Western European" languages.
Example:
The accented letter à
has Unicode codepoint 0xE0
(224) - the same as in ISO-8859-1
. However, due to the nature of UTF-8 encoding, this single codepoint is represented as 2 bytes - 0xC3 0xA0
, whereas trying to pass the single byte 0xE0
is invalid under UTF-8.
Here's a demonstration of the problem using the string voilà
encoded as ISO-8859-1
, with the à
represented as one byte (via an ANSI-C-quoted bash string ($'...'
) that uses \x{e0}
to create the byte):
Note that the sed
command is effectively a no-op that simply passes the input through, but we need it to provoke the error:
# -> 'illegal byte sequence': byte 0xE0 is not a valid char.
sed 's/.*/&/' <<<$'voil\x{e0}'
To simply ignore the problem, the above LCTYPE=C
approach can be used:
# No error, bytes are passed through ('á' will render as '?', though).
LC_CTYPE=C sed 's/.*/&/' <<<$'voil\x{e0}'
If you want to determine which parts of the input cause the problem, try the following:
# Convert bytes in the 8-bit range (high bit set) to hex. representation.
# -> 'voil\x{e0}'
iconv -f ASCII --byte-subst='\x{%02x}' <<<$'voil\x{e0}'
The output will show you all bytes that have the high bit set (bytes that exceed the 7-bit ASCII range) in hexadecimal form. (Note, however, that that also includes correctly encoded UTF-8 multibyte sequences - a more sophisticated approach would be needed to specifically identify invalid-in-UTF-8 bytes.)
Performing encoding conversions on demand:
Standard utility iconv
can be used to convert to (-t
) and/or from (-f
) encodings; iconv -l
lists all supported ones.
Examples:
Convert FROM ISO-8859-1
to the encoding in effect in the shell (based on LC_CTYPE
, which is UTF-8
-based by default), building on the above example:
# Converts to UTF-8; output renders correctly as 'voilà'
sed 's/.*/&/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"
Note that this conversion allows you to properly match foreign characters:
# Correctly matches 'à' and replaces it with 'ü': -> 'voilü'
sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"
To convert the input BACK to ISO-8859-1
after processing, simply pipe the result to another iconv
command:
sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')" | iconv -t ISO-8859-1
This worked for me - no other changes required.

I find that some of these answers are vague and complicated, I find the best way to figure out these things for sure is to just open up the console and test it yourself.
var x;
x == null // true
x == undefined // true
x === null // false
x === undefined // true
var y = null;
y == null // true
y == undefined // true
y === null // true
y === undefined // false
typeof x // 'undefined'
typeof y // 'object'
var z = {abc: null};
z.abc == null // true
z.abc == undefined // true
z.abc === null // true
z.abc === undefined // false
z.xyz == null // true
z.xyz == undefined // true
z.xyz === null // false
z.xyz === undefined // true
null = 1; // throws error: invalid left hand assignment
undefined = 1; // works fine: this can cause some problems
So this is definitely one of the more subtle nuances of JavaScript. As you can see, you can override the value of undefined
, making it somewhat unreliable compared to null
. Using the ==
operator, you can reliably use null
and undefined
interchangeably as far as I can tell. However, because of the advantage that null
cannot be redefined, I might would use it when using ==
.
For example, variable != null
will ALWAYS return false if variable
is equal to either null
or undefined
, whereas variable != undefined
will return false if variable
is equal to either null
or undefined
UNLESS undefined
is reassigned beforehand.
You can reliably use the ===
operator to differentiate between undefined
and null
, if you need to make sure that a value is actually undefined
(rather than null
).
Null
and Undefined
are two of the six built in types.4.3.9 undefined value
primitive value used when a variable has not been assigned a value
4.3.11 null value
primitive value that represents the intentional absence of any object value

The show()
method only affects the display
CSS setting. If you want to set the visibility you need to do it directly. Also, the .load_button
element is a button and does not raise a submit
event. You would need to change your selector to the form
for that to work:
$('#login_form').submit(function() {
$('#gif').css('visibility', 'visible');
});
Also note that return true;
is redundant in your logic, so it can be removed.
@Html.ActionLink("Edit","ActionName",new{id=item.id},new{onclick="functionname();"})

WordPress 5.0.2:
To remove category slug from existing posts, do this :
/%category%/%postname%/
to: /%postname%/
All posts can now be directly accessed via domain.com/%postname%/
and all categories can be accessed via domain.com/category/xyz/
. WordPress will automatically add all the 301 redirects for the old urls. So, if someone accesses domain.com/%category%/%postname%/
, they will automatically get redirected to domain.com/%postname%/
.
If you need a body in your response, you can call
return StatusCode(StatusCodes.Status500InternalServerError, responseObject);
This will return a 500 with the response object...

Looks like everyone is answering One-to-many
vs. Many-to-many
:
The difference between One-to-many
, Many-to-one
and Many-to-Many
is:
One-to-many
vs Many-to-one
is a matter of perspective. Unidirectional
vs Bidirectional
will not affect the mapping but will make difference on how you can access your data.
Many-to-one
the many
side will keep reference of the one
side. A good example is "A State has Cities". In this case State
is the one side and City
is the many side. There will be a column state_id
in the table cities
.In unidirectional,
Person
class will haveList<Skill> skills
butSkill
will not havePerson person
. In bidirectional, both properties are added and it allows you to access aPerson
given a skill( i.e.skill.person
).
One-to-Many
the one side will be our point of reference. For example, "A User has Addresses". In this case we might have three columns address_1_id
, address_2_id
and address_3_id
or a look up table with multi column unique constraint on user_id
on address_id
.In unidirectional, a
User
will haveAddress address
. Bidirectional will have an additionalList<User> users
in theAddress
class.
Many-to-Many
members of each party can hold reference to arbitrary number of members of the other party. To achieve this a look up table is used. Example for this is the relationship between doctors and patients. A doctor can have many patients and vice versa.JavaScript:
document.getElementsByTagName('head')[0].appendChild( ... );
Make DOM element like so:
link=document.createElement('link');
link.href='href';
link.rel='rel';
document.getElementsByTagName('head')[0].appendChild(link);
git pull origin master
will fetch all the changes from the remote's master branch and will merge it into your local.We generally don't use git pull origin/master.We can do the same thing by git merge origin/master
.It will merge all the changes from "cached copy" of origin's master branch into your local branch.In my case git pull origin/master
is throwing the error.

i got the same issue, i updated the hosts file with the server address and it worked
If you only want to use pure HTML and CSS i've got a solution for your problem:
In this jsFiddle you can see a non-script solution that provides a table with a fixed header.
It shouldn't be a problem to adapt the markup for a fixed first column as well.
You would just need to create a absolute-positioned table for the first column inside the hWrapper
-div and reposition the vWrapper
-div.
Providing dynamic content should not be a problem using server-side or browser-side tempting-engines, my solution works well in all modern browsers and older browsers from IE8 onwards.

Options > Properties/Settings > Viewing > Main window color
If you're doing something like
for /l %%i in (1,1,500) do @echo %time%
or
if foo (
echo %time%
do_something
echo %time%
)
then you could simply put a setlocal enabledelayedexpansion
at the beginning of your batch file and use !time!
instead of %time%
which gets evaluated on execution, not on parsing the line (which includes complete blocks enclosed in parentheses).
Try this. It worked for me.
Go to RUN and type gpedit.msc then completely disable Onedrive. Have you noticed that the problem only existed after the last large download from Microsoft? It contained this package. I also removed it from the Start menu.
This appears to be the cause of the issue. Something to do with downloading temporary files, which of course an applet is.
Once done everything went back to normal.
Code posted by you is correct and should have worked. But check exactly what you have in the char*
. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL
. Check what you have in the char*
against maximum values that float
and double
can represent on your computer.
Check this page for strtod
reference and this page for atof
reference.
I have tried the example you provided in both Windows and Linux and it worked fine.
PHP error_reporting reference:
// Turn off all error reporting
error_reporting(0);
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
// Report all PHP errors

Starting with TypeScript 2.2 using dot notation to access indexed properties is allowed. You won't get error TS2339 on your example.
See Dotted property for types with string index signatures in TypeScript 2.2 release note.
You have to catch the SIGINT signal (we are talking POSIX right?)
See @Gab Royer´s answer for sigaction.
Example:
#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
void my_handler(sig_t s){
printf("Caught signal %d\n",s);
exit(1);
}
int main(int argc,char** argv)
{
signal (SIGINT,my_handler);
while(1);
return 0;
}
Your code works well you just mistyped this line of code:
document.getElementbyId('lc').appendChild(element);
change it with this: (The "B" should be capitalized.)
document.getElementById('lc').appendChild(element);

<head>_x000D_
_x000D_
<script>_x000D_
_x000D_
function test() {_x000D_
_x000D_
var element = document.createElement("div");_x000D_
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));_x000D_
document.getElementById('lc').appendChild(element);_x000D_

Try this, working fine -
$array = json_decode(json_encode($array), true);
there are BETTER solutions, but the easiest solution is here: set the textbox text to your desired string then create a function that deletes the text, have that function fire on textbox Focus Enter event
Using contains didn't work well for my string with special characters. Find worked though.
df[df['A'].str.find("hello") != -1]
I needed clean and lightweight solution (so no jQuery and alike), which will look exactly like plain HTML, would also continue working when only plain HTML is preset (so javascript will only enhance it), and which will allow searching by starting letters (including national UTF-8 letters) if possible where it does not add extra weight. It also must work fast on very slow browsers (think rPi - so preferably no javascript executing after page load).
In firefox it uses CSS identing and thus allow searching by letters, and in other browsers it will use
prepending (but there it does not support quick search by letters). Anyway, I'm quite happy with results.

There's a bit of confusion in your question:
Date
datatype doesn't save the time zone component. This piece of information is truncated and lost forever when you insert a TIMESTAMP WITH TIME ZONE
into a Date
.TO_CHAR
function. In Oracle, a Date
has no format: it is a point in time.TO_TIMESTAMP_TZ
to convert a VARCHAR2
to a TIMESTAMP
, but this won't convert a Date
to a TIMESTAMP
.FROM_TZ
to add the time zone information to a TIMESTAMP
(or a Date
).CST
is a time zone but CDT
is not. CDT
is a daylight saving information.CST/CDT
(-05:00
) and CST/CST
(-06:00
) will have different values obviously, but the time zone CST
will inherit the daylight saving information depending upon the date by default.So your conversion may not be as simple as it looks.
Assuming that you want to convert a Date
d
that you know is valid at time zone CST/CST
to the equivalent at time zone CST/CDT
, you would use:
SQL> SELECT from_tz(d, '-06:00') initial_ts,
2 from_tz(d, '-06:00') at time zone ('-05:00') converted_ts
3 FROM (SELECT cast(to_date('2012-10-09 01:10:21',
4 'yyyy-mm-dd hh24:mi:ss') as timestamp) d
5 FROM dual);
INITIAL_TS CONVERTED_TS
------------------------------- -------------------------------
09/10/12 01:10:21,000000 -06:00 09/10/12 02:10:21,000000 -05:00
My default timestamp format has been used here. I can specify a format explicitely:
SQL> SELECT to_char(from_tz(d, '-06:00'),'yyyy-mm-dd hh24:mi:ss TZR') initial_ts,
2 to_char(from_tz(d, '-06:00') at time zone ('-05:00'),
3 'yyyy-mm-dd hh24:mi:ss TZR') converted_ts
4 FROM (SELECT cast(to_date('2012-10-09 01:10:21',
5 'yyyy-mm-dd hh24:mi:ss') as timestamp) d
6 FROM dual);
INITIAL_TS CONVERTED_TS

In WAMP the files are served by the Apache component (the A in WAMP).
In Apache, by default the files served are located in the subdirectory htdocs
of the installation directory. But this can be changed, and is actually changed when WAMP installs Apache.
The location from where the files are served is named the DocumentRoot
, and is defined using a variable in Apache configuration file. The default value is the subdirectory htdocs
relative to what is named the ServerRoot
directory.
By default the ServerRoot
is the installation directory of Apache. However this can also be redefined into the configuration file, or using the -d
option of the command httpd
which is used to launch Apache. The value in the configuration file overrides the -d
option.
The configuration file is by default conf/httpd.conf
relative to ServerRoot
. But this can be changed using the -f
option of command httpd.
When WAMP installs itself, it modify the default configuration file with DocumentRoot c:/wamp/www/
. The files to be served need to be located here and not in the htdocs
default directory.
You may change this location set by WAMP, either by modifying DocumentRoot
in the default configuration file, or by using one of the two command line options -f
or -d
which point explicitly or implicity to a new configuration file which may hold a different value for DocumentRoot
(in that case the new file needs to contain this definition, but also the rest of the configuration found in the default configuration file).

You simply cannot. DataFrames
, same as other distributed data structures, are not iterable and can be accessed using only dedicated higher order function and / or SQL methods.
You can of course collect
for row in df.rdd.collect():
do_something(row)
or convert toLocalIterator
for row in df.rdd.toLocalIterator():
do_something(row)
and iterate locally as shown above, but it beats all purpose of using Spark.
ng --version
or short ng v
kinda correct answers, but there are some important details:
If you running
ng v
inside your angular cli project folder it will show your local cli version installed in your project (package.json)If you running
ng v
outside your angular cli project folder it will always show the global cli version
The fastest way to check if a string contains another string is using indexOf
:
if (code.indexOf('ST1') !== -1) {
// string code has "ST1" in it
} else {
// string code does not have "ST1" in it
}
From Python documentation. Using the built in format() function you can specify hexadecimal base using an 'x' or 'X' Example:
x= 255 print('the number is {:x}'.format(x))
Output:
the number is ff
Here are the base options
Type
'b' Binary format. Outputs the number in base 2.
'c' Character. Converts the integer to the corresponding unicode character before printing.
'd' Decimal Integer. Outputs the number in base 10.
'o' Octal format. Outputs the number in base 8.
'x' Hex format. Outputs the number in base 16, using lower- case letters for the digits above 9.
'X' Hex format. Outputs the number in base 16, using upper- case letters for the digits above 9.
'n' Number. This is the same as 'd', except that it uses the current locale setting to insert the appropriate number separator characters.
None The same as 'd'.
There are a few steps you need to take to properly store this information in your localStorage. Before we get down to the code however, please note that localStorage (at the current time) cannot hold any data type except for strings. You will need to serialize the array for storage and then parse it back out to make modifications to it.
Step 1:
The First code snippet below should only be run if you are not already storing a serialized array in your localStorage session
variable.
To ensure your localStorage is setup properly and storing an array, run the following code snippet first:
var a = [];
a.push(JSON.parse(localStorage.getItem('session')));
localStorage.setItem('session', JSON.stringify(a));
The above code should only be run once and only if you are not already storing an array in your localStorage session
variable. If you are already doing this skip to step 2.
Step 2:
Modify your function like so:
function SaveDataToLocalStorage(data)
{
var a = [];
// Parse the serialized data back into an aray of objects
a = JSON.parse(localStorage.getItem('session')) || [];
// Push the new data (whether it be an object or anything else) onto the array
a.push(data);
// Alert the array value
alert(a); // Should be something like [Object array]
// Re-serialize the array back into a string and store it in localStorage
localStorage.setItem('session', JSON.stringify(a));
}
This should take care of the rest for you. When you parse it out, it will become an array of objects.
Hope this helps.
You may find that gnuplot's for loops are useful in this case, if you adjust your filenames or graph titles appropriately.
e.g.
filenames = "first second third fourth fifth"
plot for [file in filenames] file."dat" using 1:2 with lines
and
filename(n) = sprintf("file_%d", n)
plot for [i=1:10] filename(i) using 1:2 with lines
You should use adapter.notifyDataSetChanged()
. What does the logs says when you use that?
I believe that I found the correct answer through this dig How To. I was able to look up the SPF records on a specific DNS, by using the following query:

When compare something with Boolean it works like following
Step 1: Convert boolean
to Number
Number(true) // 1
and Number(false) // 0
Step 2: Compare both sides
boolean == someting
-> Number(boolean) === someting
If compare 1
and 2
with true
you will get the following results
true == 1
-> Number(true) === 1
-> 1 === 1
-> true
And
true == 2
-> Number(true) === 1
-> 1 === 2
-> false
Pay attention that in http.Request header "Host" can not be set via Set
method
req.Header.Set("Host", "domain.tld")
but can be set directly:
req.Host = "domain.tld"
:
req, err := http.NewRequest("GET", "http://10.0.0.1/", nil)
if err != nil {
...
}
req.Host = "domain.tld"
client := &http.Client{}
resp, err := client.Do(req)
DROP TABLE deletes the table.
TRUNCATE TABLE empties it, but leaves its structure for future data.
Many answers on starting something at boot, but often you want to start it just a little later, because your script depends on e.g. networking. Use at
to just add this delay, e.g.:
at now + 1 min -f /path/yourscript
You may add this in /etc/rc.local, but also in cron
like:
# crontab -e
@reboot at now + 1 min -f /path/yourscript
Isn't it fun to combine cron and at? Info is in the man page man at
.
As for the comments that @reboot may not be widely supported, just try it. I found out that /etc/rc.local has become obsolete on distros that support systemd, such as ubuntu and raspbian.

I think that is what you want, but i don't have access to oracle to test it right now.
Although Apple recommends tel:
in their docs for Mobile Safari, currently (iOS 4.3) it accepts callto:
just the same. So I recommend using callto:
on a generic web site as it works with both Skype and iPhone and I expect it will work on Android phones, too.
This is still a matter of deciding what you want your web page to offer. On my websites I provide both tel:
and callto:
links (the latter labeled as being for Skype) since Desktop browsers on Mac don't do anything with tel:
links while mobile Android doesn't do anything with callto:
links. Even Google Chrome with the Google Talk plugin does not respond to tel:
links. Still, I prefer offering both links on the desktop in case someone has gone to the trouble of getting tel:
links to work on their computer.
If the site design dictated that I only provide one link, I'd use a tel:
link that I would try to change to callto:
on desktop browsers.

For command line (i.e. - makefile) users only:
You (like me) probably "tuned" your makefile to #1, above, via something like this:
MS_SDK_BASE_DOS := C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A
ENV_SET := LIB="$(MS_SDK_BASE_DOS)\Lib\x64"
But, now, you need to change that tuning to #2, above, like this:
MS_SDK_BASE_DOS := C:\Program Files\Microsoft SDKs\Windows\v7.1
(Don't miss the "v7.0A" to "v7.1" change, as well.)
I need to have a 32 bit JRE available for my browser, but 64 bit JRE for R and rJava. The 32 bit JRE is installed in the default location. After some experimentation, I found that I only needed one of misterbee's suggestions to get rJava (version 0.9-6) working for me. All I did was add the path to my 64 bit java installation:
C:\apps\Java\jre\bin\server\jvm.dll
to the top of my path environment variable (your path will likely be different) and remove my JAVA_HOME as user2161065 suggested. I put this just ahead of the entry
C:\ProgramData\Oracle\Java\javapath
which the Oracle installer inserts at the top of the path and points to some symlinks to the 32 bit JRE. By adding the entry to 64 bit jvm.dll, looks like rJava could find what it needs.

I think stash -p
is probably the choice you want, but just in case you run into other even more tricky things in the future, remember that:
Stash
is really just a very simple alternative to the only slightly more complex branch
sets. Stash is very useful for moving things around quickly, but you can accomplish more complex things with branches without that much more headache and work.
# git checkout -b tmpbranch
# git add the_file
# git commit -m "stashing the_file"
# git checkout master
go about and do what you want, and then later simply rebase
and/or merge
the tmpbranch. It really isn't that much extra work when you need to do more careful tracking than stash will allow.
I want to add another pitfall. Even if you did everything right, you may get trapped by this error if you support more than one target in your build process.
The image asset catalog is part of a target and even if you selected it in Xcode5 to be used for your target, it does not mean it is automatically added.
As a result, the build works like a charm, but the asset catalog is not added to the IPA and the AppStore validation fails with the Error, that the icons are missing.
To fix or check that the assets are part of the target, select the assets-entry in the Xcode project and make sure your target is checked in the inspector.

you can also connect to database as "normal" user (not postgres):
postgres=# \connect opensim Opensim_Tester localhost;
Password for user Opensim_Tester:
You are now connected to database "opensim" as user "Opensim_Tester" on host "localhost" at port "5432"
You can't alter the existing columns for identity.
You have 2 options,
Create a new table with identity & drop the existing table
Create a new column with identity & drop the existing column
Approach 1. (New table) Here you can retain the existing data values on the newly created identity column.
CREATE TABLE dbo.Tmp_Names
(
Id int NOT NULL
IDENTITY(1, 1),
Name varchar(50) NULL
)
ON [PRIMARY]
go
SET IDENTITY_INSERT dbo.Tmp_Names ON
go
IF EXISTS ( SELECT *
FROM dbo.Names )
INSERT INTO dbo.Tmp_Names ( Id, Name )
SELECT Id,
Name
FROM dbo.Names TABLOCKX
go
SET IDENTITY_INSERT dbo.Tmp_Names OFF
go
DROP TABLE dbo.Names
go
Exec sp_rename 'Tmp_Names', 'Names'
Approach 2 (New column) You can’t retain the existing data values on the newly created identity column, The identity column will hold the sequence of number.
Alter Table Names
Add Id_new Int Identity(1, 1)
Go
Alter Table Names Drop Column ID
Go
Exec sp_rename 'Names.Id_new', 'ID', 'Column'
See the following Microsoft SQL Server Forum post for more details:
opencv has changed some functions and moved them to their opencv_contrib repo so you have to call the mentioned method with:
recognizer = cv2.face.createLBPHFaceRecognizer()
Note: You can see this issue about missing docs. Try using help function help(cv2.face.createLBPHFaceRecognizer)
for more details.
Thanks all for your replies. I wrote one myself. Please note that this uses jQuery.

I like the result I got here which i think is easy to read and short enough to fit as a solution.
