df.isna()
return True values for NaN, False for the rest. So, doing:
df.isna().any()
will return True for any column having a NaN, False for the rest
If you added JComponent
to already visible Container, then you have call
frame.getContentPane().validate();
frame.getContentPane().repaint();
for example
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
public class Main {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setSize(460, 500);
frame.setTitle("Circles generator");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
frame.setVisible(true);
}
});
String input = JOptionPane.showInputDialog("Enter n:");
CustomComponents0 component = new CustomComponents0();
frame.add(component);
frame.getContentPane().validate();
frame.getContentPane().repaint();
}
static class CustomComponents0 extends JLabel {
private static final long serialVersionUID = 1L;
@Override
public Dimension getMinimumSize() {
return new Dimension(200, 100);
}
@Override
public Dimension getPreferredSize() {
return new Dimension(300, 200);
}
@Override
public void paintComponent(Graphics g) {
int margin = 10;
Dimension dim = getSize();
super.paintComponent(g);
g.setColor(Color.red);
g.fillRect(margin, margin, dim.width - margin * 2, dim.height - margin * 2);
}
}
}
This article seems to show the valid types that are acceptable
<time>2009-11-13</time>
<!-- without @datetime content must be a valid date, time, or precise datetime -->
<time datetime="2009-11-13">13<sup>th</sup> November</time>
<!-- when using @datetime the content can be anything relevant -->
<time datetime="20:00">starting at 8pm</time>
<!-- time example -->
<time datetime="2009-11-13T20:00+00:00">8pm on my birthday</time>
<!-- datetime with time-zone example -->
<time datetime="2009-11-13T20:00Z">8pm on my birthday</time>
<!-- datetime with time-zone “Z” -->
This one covers using it in the <input>
field:
<input type="date" name="d" min="2011-08-01" max="2011-08-15">
This example of the HTML5 input type "date" combine with the attributes min and max shows how we can restrict the dates a user can input. The attributes min and max are not dependent on each other and can be used independently.
<input type="time" name="t" value="12:00">
The HTML5 input type "time" allows users to choose a corresponding time that is displayed in a 24hour format. If we did not include the default value of "12:00" the time would set itself to the time of the users local machine.
<input type="week" name="w">
The HTML5 Input type week will display the numerical version of the week denoted by a "W" along with the corresponding year.
<input type="month" name="m">
The HTML5 input type month does exactly what you might expect it to do. It displays the month. To be precise it displays the numerical version of the month along with the year.
<input type="datetime" name="dt">
The HTML5 input type Datetime displays the UTC date and time code. User can change the the time steps forward or backward in one minute increments. If you wish to display the local date and time of the user you will need to use the next example datetime-local
<input type="datetime-local" name="dtl" step="7200">
Because datetime steps through one minute at a time, you may want to change the default increment by using the attribute "step". In the following example we will have it increment by two hours by setting the attribute step to 7200 (60seconds X 60 minutes X 2).
I had the same error when initializing Spring on startup, using some different library versions, but everything worked when I got my versions in this order in the classpath (the other libraries in the cp were not important):
I use this function which uses bc
and thus supports floating point calculations:
c () {
local a
(( $# > 0 )) && a="$@" || read -r -p "calc: " a
bc -l <<< "$a"
}
Example:
$ c '5*5'
25
$ c 5/5
1.00000000000000000000
$ c 3.4/7.9
.43037974683544303797
Bash's arithmetic expansion doesn't support floats (but Korn shell and zsh do).
Example:
$ ksh -c 'echo "$((3.0 / 4))"'
0.75
For Angular version 4+, you don't need to use any complex solution. You can simply use [routerLinkActive]="'is-active'"
.
For an example with bootstrap 4 nav link:
<ul class="navbar-nav mr-auto">
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="/home">Home</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="/about-us">About Us</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link " routerLink="/contact-us">Contact</a>
</li>
</ul>
This is what I do when I need Initialized Global Constants:
1. Add a module called Globals
2. Add Properties like this into the Globals
module:
Property Get PSIStartRow() As Integer
PSIStartRow = Sheets("FOB Prices").Range("F1").Value
End Property
Property Get PSIStartCell() As String
PSIStartCell = "B" & PSIStartRow
End Property
The simplest solution I can think of is removing the whole directory with
RD /S /Q folderPath
Then creating this directory again:
MD folderPath
// this will give all the forms on the page.
$('form')
// If you know the name of form then.
$('form[name="myFormName"]')
// If you don't know know the name but the position (starts with 0)
$('form:eq(1)') // 2nd form will be fetched.
To overwrite one file's content to another file. use cat eg.
echo "this is foo" > foobar.txt
cat foobar.txt
echo "this is bar" > bar.txt
cat bar.txt
Now to overwrite foobar we can use a cat command as below
cat bar.txt >> foobar.txt
cat foobar.txt
Since PHP 5.5 you can use class name resolution via ClassName::class.
<?php
namespace Name\Space;
class ClassName {}
echo ClassName::class;
?>
If you want to use this feature in your class method use static::class:
<?php
namespace Name\Space;
class ClassName {
/**
* @return string
*/
public function getNameOfClass()
{
return static::class;
}
}
$obj = new ClassName();
echo $obj->getNameOfClass();
?>
For older versions of PHP, you can use get_class().
If you need a function try this.
First we'll create a type:
CREATE OR REPLACE TYPE T_TABLE IS OBJECT
(
Field1 int
, Field2 VARCHAR(25)
);
CREATE TYPE T_TABLE_COLL IS TABLE OF T_TABLE;
/
Then we'll create the function:
CREATE OR REPLACE FUNCTION TEST_RETURN_TABLE
RETURN T_TABLE_COLL
IS
l_res_coll T_TABLE_COLL;
l_index number;
BEGIN
l_res_coll := T_TABLE_COLL();
FOR i IN (
WITH TAB AS
(SELECT '1001' ID, 'A,B,C,D,E,F' STR FROM DUAL
UNION
SELECT '1002' ID, 'D,E,F' STR FROM DUAL
UNION
SELECT '1003' ID, 'C,E,G' STR FROM DUAL
)
SELECT id,
SUBSTR(STR, instr(STR, ',', 1, lvl) + 1, instr(STR, ',', 1, lvl + 1) - instr(STR, ',', 1, lvl) - 1) name
FROM
( SELECT ',' || STR || ',' AS STR, id FROM TAB
),
( SELECT level AS lvl FROM dual CONNECT BY level <= 100
)
WHERE lvl <= LENGTH(STR) - LENGTH(REPLACE(STR, ',')) - 1
ORDER BY ID, NAME)
LOOP
IF i.ID = 1001 THEN
l_res_coll.extend;
l_index := l_res_coll.count;
l_res_coll(l_index):= T_TABLE(i.ID, i.name);
END IF;
END LOOP;
RETURN l_res_coll;
END;
/
Now we can select from it:
select * from table(TEST_RETURN_TABLE());
Output:
SQL> select * from table(TEST_RETURN_TABLE());
FIELD1 FIELD2
---------- -------------------------
1001 A
1001 B
1001 C
1001 D
1001 E
1001 F
6 rows selected.
Obviously you'd need to replace the WITH TAB AS...
bit with where you would be getting your actual data from.

Same functionality I prefer than using much heavy jQuery mobile is Carousel Swipe. I suggest directly jump in to source code on github, and copy file carousel-swipe.js
in to your project directory.
Use swiper events as bellow:
$('#carousel-example-generic').carousel({
interval: false
});

Like Marcelo's version, it uses an is_container type trait that must be specialized for all containers that are to be supported. It may be possible to use a trait to check for value_type
, const_iterator
, begin()
/end()
, but I'm not sure I'd recommend that since it might match things that match those criteria but aren't actually containers, like std::basic_string
. Also like Marcelo's version, it uses templates that can be specialized to specify the delimiters to use.
The major difference is that I've built my version around a pretty_ostream_iterator
, which works similar to the std::ostream_iterator
but doesn't print a delimiter after the last item. Formatting the containers is done by the print_container_helper
, which can be used directly to print containers without an is_container trait, or to specify a different delimiters type.
I've also defined is_container and delimiters so it will work for containers with non-standard predicates or allocators, and for both char and wchar_t. The operator<< function itself is also defined to work with both char and wchar_t streams.
Finally, I've used std::enable_if
, which is available as part of C++0x, and works in Visual C++ 2010 and g++ 4.3 (needs the -std=c++0x flag) and later. This way there is no dependency on Boost.
The child process environment is lost in the moment it ceases to exist, and moving the environment content from there to the parent is somewhat tricky.
You probably need to spawn a shell script (you can generate one dynamically to /tmp) which will output the virtualenv environment variables to a file, which you then read in the parent Python process and put in os.environ.
Or you simply parse the activate script in using for the line in open("bin/activate"), manually extract stuff, and put in os.environ. It is tricky, but not impossible.
Here is what made the error disappear for me:
Close eclipse, open up a terminal window and run:
$ mvn clean eclipse:clean eclipse:eclipse
Are you using Maven? If so,
To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.
And then clean
Edit 1:
If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.
Edit 2:
You can also try going into the folder where you have all your projects and delete the .metadata
for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.
Try code below:
console.log(event['target'].value)
it works for me :-)
It seems that without return()
it's faster...
library(rbenchmark)
x <- 1
foo <- function(value) {
return(value)
}
fuu <- function(value) {
value
}
benchmark(foo(x),fuu(x),replications=1e7)
test replications elapsed relative user.self sys.self user.child sys.child
1 foo(x) 10000000 51.36 1.185322 51.11 0.11 0 0
2 fuu(x) 10000000 43.33 1.000000 42.97 0.05 0 0
____EDIT __________________
I proceed to others benchmark (benchmark(fuu(x),foo(x),replications=1e7)
) and the result is reversed... I'll try on a server.

This is easy way to do this
$('#datepicker').datepicker('setStartDate', new Date());
also we can disable future days
$('#datepicker').datepicker('setEndDate', new Date());
When you say "is there an easier way to... trust this cert", that's exactly what you're doing by adding the cert to your Java trust store. And this is very, very easy to do, and there's nothing you need to do within your client app to get that trust store recognized or utilized.
On your client machine, find where your cacerts file is (that's your default Java trust store, and is, by default, located at <java-home>/lib/security/certs/cacerts.
Then, type the following:
keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to cacerts>
That will import the cert into your trust store, and after this, your client app will be able to connect to your Grizzly HTTPS server without issue.
If you don't want to import the cert into your default trust store -- i.e., you just want it to be available to this one client app, but not to anything else you run on your JVM on that machine -- then you can create a new trust store just for your app. Instead of passing keytool the path to the existing, default cacerts file, pass keytool the path to your new trust store file:
keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to new trust store>
You'll be asked to set and verify a new password for the trust store file. Then, when you start your client app, start it with the following parameters:
java -Djavax.net.ssl.trustStore=<path to new trust store> -Djavax.net.ssl.trustStorePassword=<trust store password>
Easy cheesy, really.
If you don't mind using regular expressions, then this function would give you much power in renaming files:
import re, glob, os
def renamer(files, pattern, replacement):
for pathname in glob.glob(files):
basename= os.path.basename(pathname)
new_filename= re.sub(pattern, replacement, basename)
if new_filename != basename:
os.rename(
pathname,
os.path.join(os.path.dirname(pathname), new_filename))
So in your example, you could do (assuming it's the current directory where the files are):
renamer("*.doc", r"^(.*)\.doc$", r"new(\1).doc")
but you could also roll back to the initial filenames:
renamer("*.doc", r"^new\((.*)\)\.doc", r"\1.doc")
and more.
Use jquery-dateFormat. It will solve your problem.
You need to include the jquery.dateFormat in your html file.
<script>
var date = $('#scheduleDate').val();
document.write($.format.date(date, "dd,MM,yyyy"));
var dateTypeVar = $('#scheduleDate').datepicker('getDate');
document.write($.format.date(dateTypeVar, "dd-MM-yy"));
</script>
A really simple implementation is:
out = "".join(c for c in asking if c not in ('!','.',':'))
and keep adding any other types of punctuation.
A more efficient way would be
import string
stringIn = "string.with.punctuation!"
out = stringIn.translate(stringIn.maketrans("",""), string.punctuation)
Edit: There is some more discussion on efficiency and other implementations here: Best way to strip punctuation from a string in Python
The single most important difference between the two is that you should start using JupyterLab straight away, and that you should not worry about Jupyter Notebook at all. Because:
JupyterLab will eventually replace the classic Jupyter Notebook. Throughout this transition, the same notebook document format will be supported by both the classic Notebook and JupyterLab
Other posts have suggested that Jupyter Notebook (JN) could potentially be easier to use than JupyterLab (JL) for beginners. But I would have to disagree.
A great advantage with JL, and arguably one of the most important differences between JL and JN, is that you can more easily run a single line and even highlighted text. I prefer using a keyboard shortcut for this, and assigning shortcuts is pretty straight-forward.
And the fact that you can execute code in a Python console makes JL much more fun to work with. Other answers have already mentioned this, but JL can in some ways be considered a tool to run Notebooks and more. So the way I use JupyterLab is by having it set up with an .ipynb file, a file browser and a python console like this:
And now you have these tools at your disposal:
Ctrl+Enter
Shift+Enter
You should try this code.
$("#multiple_Package_Ids_checkboxes").on('change', function (e) {
var totAmt = 0;
$.each($(this).find(":selected"), function (i, item) {
totAmt += $(item).data("price");
});
$("#PackTotAmt").text(totAmt);
});
domContentLoaded: marks the point when both the DOM is ready and there are no stylesheets that are blocking JavaScript execution - meaning we can now (potentially) construct the render tree. Many JavaScript frameworks wait for this event before they start executing their own logic. For this reason the browser captures the EventStart and EventEnd timestamps to allow us to track how long this execution took.
loadEvent: as a final step in every page load the browser fires an “onload” event which can trigger additional application logic.
You can specify git log
options to show only the last commit, -1
, and a format that includes only the commit ID, like this:
git log -1 --format=%H
If you prefer the shortened commit ID:
git log -1 --format=%h
Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000
if((a.trim()=="")||(a=="")||(a==null))
{
//empty condition
}
else
{

method was removed from jQuery in version 1.9. You can do this instead:
$(document).ready(function() {
$('#showmenu').click(function() {
$('.menu').slideToggle("fast");
});
});
Demo: http://jsfiddle.net/APA2S/1/
...but as with the code in your question that would slide up or down. To slide left or right you can do the following:
$(document).ready(function() {
$('#showmenu').click(function() {
$('.menu').toggle("slide");
});
});
Demo: http://jsfiddle.net/APA2S/2/
Noting that this requires jQuery-UI's slide effect, but you added that tag to your question so I assume that is OK.
In rpy2, the way to get the very same operator as "[" with R is to use ".rx". See the documentation about extracting with rpy2
For creating vectors, if you know your way around with Python there should not be any issue. See the documentation about creating vectors
You need to use event.stopPropagation()
$('#childDiv').click(function(event){
event.stopPropagation();
alert(event.target.id);
});?
Description: Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
This is a possible answer, this will also give the precise data, just need to change the decimal point in the required form.
public class TestStandAlone { /** *This method is to main
* @param args void */ public static void main(String[] args) { // TODO Auto-generated method stub try { Float f1=152.32f; BigDecimal roundfinalPrice = new BigDecimal(f1.floatValue()).setScale(2,BigDecimal.ROUND_HALF_UP); System.out.println("f1 --> "+f1); String s1=roundfinalPrice.toPlainString(); System.out.println("s1 "+s1); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
Output will be
f1 --> 152.32 s1 152.32
Use preg_grep
$array = preg_grep(
'/(my\n+string\n+)/i',
array( 'file' , 'my string => name', 'this')
);
I resolve this (On Eclipse IDE) by delete my old server and create the same again. This error is because you don't proper terminate Tomcat server and close Eclipse.
Style the ::-ms-clear
pseudo-element for the box:
.someinput::-ms-clear {
display: none;
}
You can use templated interfaces like this:
interface Map<T> {
[K: string]: T;
}
let dict: Map<number> = {};
dict["one"] = 1;
Took me couple trials, had same issue, this worked for me:
Check your spelling at -
(BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
I corrected mine at textField
instead of textfield
, capitalise "F"... and bingo!! it worked..
You can use pgrep
as long as you include the -f
options. That makes pgrep
match keywords in the whole command (including arguments) instead of just the process name.
pgrep -f keyword
From the man page:
-f
The pattern is normally only matched against the process name. When-f
is set, the full command line is used.
If you really want to avoid pgrep, try:
ps -ef | awk '/[k]eyword/{print $2}'
Note the []
around the first letter of the keyword. That's a useful trick to avoid matching the awk
command itself.
If you can afford working via the file data, you can do
find -mmin +14400 -delete
You'll need to create an instance of the class and invoke the method on it.
public class Foo
{
public void Data1()
{
}
public static void Data2()
{
Foo foo = new Foo();
foo.Data1();
}
}
Here is code to get line number and column position
function getLineNumber(tArea) {
return tArea.value.substr(0, tArea.selectionStart).split("\n").length;
}
function getCursorPos() {
var me = $("textarea[name='documenttext']")[0];
var el = $(me).get(0);
var pos = 0;
if ('selectionStart' in el) {
pos = el.selectionStart;
} else if ('selection' in document) {
el.focus();
var Sel = document.selection.createRange();
var SelLength = document.selection.createRange().text.length;
Sel.moveStart('character', -el.value.length);
pos = Sel.text.length - SelLength;
}
var ret = pos - prevLine(me);
alert(ret);
return ret;
}
function prevLine(me) {
var lineArr = me.value.substr(0, me.selectionStart).split("\n");
var numChars = 0;
for (var i = 0; i < lineArr.length-1; i++) {
numChars += lineArr[i].length+1;
}
return numChars;
}
tArea is the text area DOM element
As per HTML5, you can use
input type="datetime-local"
instead of
input type="date"
.
It will allow the [(ngModel)]
directive to read and write value from input control.
Note: If the date string contains 'Z' then to implement above solution, you need to trim the 'Z' character from date.
For more details, please go through this link on mozilla docs.
SortedList decorator from Java Happy Libraries can be used to decorate TreeList from Apache Collections. That would produce a new list which performance is compareable to TreeSet. https://sourceforge.net/p/happy-guys/wiki/Sorted%20List/
I happened to be working in localhost , in windows 10, using WAMP, as it turns out, Wamp has a really accessible configuration interface to change the MySQL configuration. You just need to go to the Wamp panel, then to MySQL, then to settings and change the mode to sql-mode: none.(essentially disabling the strict mode) The following picture illustrates this.
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != ".." && strtolower(substr($file, strrpos($file, '.') + 1)) == 'xml')
{
$thelist .= '<li><a href="'.$file.'">'.$file.'</a></li>';
}
}
closedir($handle);
}
A simple way to look at the extension using substr and strrpos
You could try using a templating library like Apache Velocity.
Here is an example:
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.Velocity;
import java.io.StringWriter;
public class TemplateExample {
public static void main(String args[]) throws Exception {
Velocity.init();
VelocityContext context = new VelocityContext();
context.put("name", "Mark");
context.put("invoiceNumber", "42123");
context.put("dueDate", "June 6, 2009");
String template = "Hello $name. Please find attached invoice" +
" $invoiceNumber which is due on $dueDate.";
StringWriter writer = new StringWriter();
Velocity.evaluate(context, writer, "TemplateName", template);
System.out.println(writer);
}
}
The output would be:
Hello Mark. Please find attached invoice 42123 which is due on June 6, 2009.
ok in addition to @user3096626 answer i think it will be more helpful if someone provided code example, the following example will show you how to fix image orientation comes from url (remote images):
Solution 1: using javascript (recommended)
because load-image library doesn't extract exif tags from url images only (file/blob), we will use both exif-js and load-image javascript libraries, so first add these libraries to your page as the follow:
<script src="https://cdnjs.cloudflare.com/ajax/libs/exif-js/2.1.0/exif.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image-scale.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image-orientation.min.js"></script>
Note the version 2.2 of exif-js seems has issues so we used 2.1
then basically what we will do is
a - load the image using window.loadImage()
b - read exif tags using window.EXIF.getData()
c - convert the image to canvas and fix the image orientation using window.loadImage.scale()
d - place the canvas into the document
here you go :)
window.loadImage("/your-image.jpg", function (img) {
if (img.type === "error") {
console.log("couldn't load image:", img);
} else {
window.EXIF.getData(img, function () {
var orientation = EXIF.getTag(this, "Orientation");
var canvas = window.loadImage.scale(img, {orientation: orientation || 0, canvas: true});
document.getElementById("container").appendChild(canvas);
// or using jquery $("#container").append(canvas);
});
}
});
of course also you can get the image as base64 from the canvas object and place it in the img src attribute, so using jQuery you can do ;)
$("#my-image").attr("src",canvas.toDataURL());
here is the full code on: github: https://github.com/digital-flowers/loadimage-exif-example
Solution 2: using html (browser hack)
there is a very quick and easy hack, most browsers display the image in the right orientation if the image is opened inside a new tab directly without any html (LOL i don't know why), so basically you can display your image using iframe by putting the iframe src attribute as the image url directly:
<iframe src="/my-image.jpg"></iframe>
Solution 3: using css (only firefox & safari on ios)
there is css3 attribute to fix image orientation but the problem it is only working on firefox and safari/ios it is still worth mention because soon it will be available for all browsers (Browser support info from caniuse)
img {
image-orientation: from-image;
}
If you want to return from an outer function with an error without exit
ing you can use this trick:
do-something-complex() {
# Using `return` here would only return from `fail`, not from `do-something-complex`.
# Using `exit` would close the entire shell.
# So we (ab)use a different feature. :)
fail() { : "${__fail_fast:?$1}"; }
nested-func() {
try-this || fail "This didn't work"
try-that || fail "That didn't work"
}
nested-func
}
Trying it out:
$ do-something-complex
try-this: command not found
bash: __fail_fast: This didn't work
This has the added benefit/drawback that you can optionally turn off this feature: __fail_fast=x do-something-complex
.
Note that this causes the outermost function to return 1.
You can use the built in xDocument.CreateReader() and an XmlNodeReader to convert back and forth.
Putting that into an Extension method to make it easier to work with.
using System;
using System.Xml;
using System.Xml.Linq;
namespace MyTest
{
internal class Program
{
private static void Main(string[] args)
{
var xmlDocument = new XmlDocument();
xmlDocument.LoadXml("<Root><Child>Test</Child></Root>");
var xDocument = xmlDocument.ToXDocument();
var newXmlDocument = xDocument.ToXmlDocument();
Console.ReadLine();
}
}
public static class DocumentExtensions
{
public static XmlDocument ToXmlDocument(this XDocument xDocument)
{
var xmlDocument = new XmlDocument();
using(var xmlReader = xDocument.CreateReader())
{
xmlDocument.Load(xmlReader);
}
return xmlDocument;
}
public static XDocument ToXDocument(this XmlDocument xmlDocument)
{
using (var nodeReader = new XmlNodeReader(xmlDocument))
{
nodeReader.MoveToContent();
return XDocument.Load(nodeReader);
}
}
}
}

Here is an improved version of the function from php.net that @Andrew posted.
function download_csv_results($results, $name = NULL)
{
if( ! $name)
{
$name = md5(uniqid() . microtime(TRUE) . mt_rand()). '.csv';
}
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename='. $name);
header('Pragma: no-cache');
header("Expires: 0");
$outstream = fopen("php://output", "wb");
foreach($results as $result)
{
fputcsv($outstream, $result);
}
fclose($outstream);
}
It is really easy to use and works great with MySQL(i)/PDO result sets.
download_csv_results($results, 'your_name_here.csv');
Remember to exit()
after calling this if you are done with the page.
$table->date('user_id')->nullable();
In your file create_file
, the null option must be enabled.
You could replace something in there by getting the index along with the item.
>>> foo = ['a', 'b', 'c', 'A', 'B', 'C']
>>> for index, item in enumerate(foo):
... print(index, item)
...
(0, 'a')
(1, 'b')
(2, 'c')
(3, 'A')
(4, 'B')
(5, 'C')
>>> for index, item in enumerate(foo):
... if item in ('a', 'A'):
... foo[index] = 'replaced!'
...
>>> foo
['replaced!', 'b', 'c', 'replaced!', 'B', 'C']
Note that if you want to remove something from the list you have to iterate over a copy of the list, else you will get errors since you're trying to change the size of something you are iterating over. This can be done quite easily with slices.
Wrong:
>>> foo = ['a', 'b', 'c', 1, 2, 3]
>>> for item in foo:
... if isinstance(item, int):
... foo.remove(item)
...
>>> foo
['a', 'b', 'c', 2]
The 2 is still in there because we modified the size of the list as we iterated over it. The correct way would be:
>>> foo = ['a', 'b', 'c', 1, 2, 3]
>>> for item in foo[:]:
... if isinstance(item, int):
... foo.remove(item)
...
>>> foo
['a', 'b', 'c']
I based this solution on the comments of @jberger.
if git checkout master &&
git fetch origin master &&

Code coverage has been explained well in the previous answers. So this is more of an answer to the second part of the question.
We've used three tools to determine code coverage.
We use these tools to
As blocking on keyboard input (since the input()
function blocks) is frequently not what we want to do (we'd frequently like to keep doing other stuff), here's a very-stripped-down multi-threaded example to demonstrate how to keep running your main application while still reading in keyboard inputs whenever they arrive.
This works by creating one thread to run in the background, continually calling input()
and then passing any data it receives to a queue.
In this way, your main thread is left to do anything it wants, receiving the keyboard input data from the first thread whenever there is something in the queue.
import threading
import queue
import time
def read_kbd_input(inputQueue):
print('Ready for keyboard input:')
while (True):
input_str = input()
inputQueue.put(input_str)
def main():
EXIT_COMMAND = "exit"
inputQueue = queue.Queue()
inputThread = threading.Thread(target=read_kbd_input, args=(inputQueue,), daemon=True)
inputThread.start()
while (True):
if (inputQueue.qsize() > 0):
input_str = inputQueue.get()
print("input_str = {}".format(input_str))
if (input_str == EXIT_COMMAND):
print("Exiting serial terminal.")
break
# Insert your code here to do whatever you want with the input_str.
# The rest of your program goes here.
time.sleep(0.01)
print("End.")
if (__name__ == '__main__'):

Note that Queue.put()
and Queue.get()
and other Queue class methods are thread-safe! That means they implement all the internal locking semantics required for inter-thread operations, so each function call in the queue class can be considered as a single, atomic operation. See the notes at the top of the documentation: https://docs.python.org/3/library/queue.html (emphasis added):
The queue module implements multi-producer, multi-consumer queues. It is especially useful in threaded programming when information must be exchanged safely between multiple threads. The Queue class in this module implements all the required locking semantics.
It's possible you're seeing OpenDirectory/ActiveDirectory/LDAP users "automounted" into your home directory.
In *nix, ~
will resolve to your home directory. Likewise ~X
will resolve to 'user X'.
Similar to automount for directories, OpenDirectory/ActiveDirectory/LDAP is used in larger/corporate environments to automount user directories. These users may be actual people or they can be machine accounts created to provide various features.
If you type ~Tab you'll see a list of the users on your machine.

Max has the best solution for when you always want to start both projects, but you can also right click a project and choose menu Debug ? Start New Instance.
This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).
Just use <script src="modernizr.js"></script>

They are not case sensitive. In fact NodeJS web server explicitly converts them to lower-case, before making them available in the request object.
It's important to note here that all headers are represented in lower-case only, regardless of how the client actually sent them. This simplifies the task of parsing headers for whatever purpose.

Both these will give you the first child node:
console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);
If you need the first child that is an element node then use:
console.log(parentElement.children[0]);
Edit
Ah, I see your problem now; parentElement
is an array.
If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0]
to dearray (yes, I made that word up) the element:
var parentElement = document.getElementsByClassName("uniqueClassName")[0];

I think Semaphore is what you are looking for, it will block the main process after counting down to 0. Sample code:
from multiprocessing import Process
from multiprocessing import Semaphore
import time
def f(name, sema):
print('process {} starting doing business'.format(name))
# simulate a time-consuming task by sleeping
time.sleep(5)
# `release` will add 1 to `sema`, allowing other
# processes blocked on it to continue
sema.release()
if __name__ == '__main__':
concurrency = 20
total_task_num = 1000
sema = Semaphore(concurrency)
all_processes = []
for i in range(total_task_num):
# once 20 processes are running, the following `acquire` call
# will block the main process since `sema` has been reduced
# to 0. This loop will continue only after one or more
# previously created processes complete.
sema.acquire()
p = Process(target=f, args=(i, sema))
all_processes.append(p)
p.start()
# inside main process, wait for all processes to finish
for p in all_processes:
p.join()
The following code is more structured since it acquires and releases sema
in the same function. However, it will consume too much resources if total_task_num
is very large:
from multiprocessing import Process
from multiprocessing import Semaphore
import time
def f(name, sema):
print('process {} starting doing business'.format(name))
# `sema` is acquired and released in the same
# block of code here, making code more readable,
# but may lead to problem.
sema.acquire()
time.sleep(5)
sema.release()
if __name__ == '__main__':
concurrency = 20
total_task_num = 1000
sema = Semaphore(concurrency)
all_processes = []
for i in range(total_task_num):
p = Process(target=f, args=(i, sema))
all_processes.append(p)
# the following line won't block after 20 processes
# have been created and running, instead it will carry
# on until all 1000 processes are created.
p.start()
# inside main process, wait for all processes to finish
for p in all_processes:
p.join()
The above code will create total_task_num
processes but only concurrency
processes will be running while other processes are blocked, consuming precious system resources.

If you use Kotlin, you can do the following:
1. On first, you should be create Interface
and implemented him in your Fragment
interface RefreshData {
fun refresh()
}
class YourFragment : Fragment(), RefreshData {
...
override fun refresh() {
//do what you want
}
}
2. Next step is add OnPageChangeListener
to your ViewPager
viewPager.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
override fun onPageScrollStateChanged(state: Int) { }
override fun onPageSelected(position: Int) {
viewPagerAdapter.notifyDataSetChanged()
viewPager.currentItem = position
}
override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) { }
})
3. override getItemPosition
in your Adapter
override fun getItemPosition(obj: Any): Int {
if (obj is RefreshData) {
obj.refresh()
}
return super.getItemPosition(obj)
}
I've added a max
validation to amd's great answer.
import { Directive, Input, forwardRef } from '@angular/core'
import { NG_VALIDATORS, Validator, AbstractControl, Validators } from '@angular/forms'
/*
* This is a wrapper for [min] and [max], used to work with template driven forms
*/
@Directive({
selector: '[min]',
providers: [{ provide: NG_VALIDATORS, useExisting: MinNumberValidator, multi: true }]
})
export class MinNumberValidator implements Validator {
@Input() min: number;
validate(control: AbstractControl): { [key: string]: any } {
return Validators.min(this.min)(control)
}
}
@Directive({
selector: '[max]',
providers: [{ provide: NG_VALIDATORS, useExisting: MaxNumberValidator, multi: true }]
})
export class MaxNumberValidator implements Validator {
@Input() max: number;
validate(control: AbstractControl): { [key: string]: any } {
return Validators.max(this.max)(control)
}
}
See mezzoblue for a nice summary of each technique, with strengths and weaknesses, plus example html and css.
dev.off() is the best function, but it clears also all plots. If you want to keep plots in your window, at the beginning save default par settings:
def.par = par()
Then when you use your par functions you still have a backup of default par settings. Later on, after generating plots, finish with:
par(def.par) #go back to default par settings
With this, you keep generated plots and reset par settings.
I did it this way, where 'struts2ActionName' is the struts2 action in my case. You may use any url instead.
var urlAdditionCert =${pageContext.request.contextPath}/struts2ActionName";
$("#dialogId").load( urlAdditionCert).dialog({
modal: true,
height: $("#body").height(),
width: $("#body").width()*.8
});
Check first your class loader.
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
if (classLoader == null) {
classLoader = Class.class.getClassLoader();
}
classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");
// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml
The simplest and shorter method would be the following.
string[] stringArray = { "text1", "text2", "text3", "text4" };
string value = "text3";
if(stringArray.Contains(value))
{
// Do something if the value is available in Array.
}
Here is a function I wrote to accomplish this based off of the previous answers.
CREATE FUNCTION dbo.RepetitiveReplace
(
@P_String VARCHAR(MAX),
@P_Pattern VARCHAR(MAX),
@P_ReplaceString VARCHAR(MAX),
@P_ReplaceLength INT = 1
)
RETURNS VARCHAR(MAX)
BEGIN
DECLARE @Index INT;
-- Get starting point of pattern
SET @Index = PATINDEX(@P_Pattern, @P_String);
while @Index > 0
begin
--replace matching charactger at index
SET @P_String = STUFF(@P_String, PATINDEX(@P_Pattern, @P_String), @P_ReplaceLength, @P_ReplaceString);
SET @Index = PATINDEX(@P_Pattern, @P_String);
end
RETURN @P_String;
END;
Originally I had a recursive function here which does not play well with sql server as it has a 32 nesting level limit which would result in an error like the below any time you attempt to make 32+ replacements with the function. Instead of trying to make a server level change to allow more nesting (which could be dangerous like allow never ending loops) switching to a while loop makes a lot more sense.
Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32).
If you want more control over how the conversion takes place, you can use ConvertAll:
var stringList = myList.ConvertAll(obj => obj.SomeToStringMethod());
I think there's no big difference between deflate and gzip, because gzip basically is just a header wrapped around deflate (see RFCs 1951 and 1952).
If you are including the apache commons lang jar in your project than the easiest solution would be to do:
WordUtils.capitalize(Name)
takes care of all the dirty work for you. See the javadoc here
Alternatively, you also have a capitalizeFully(String) method which also lower cases the rest of the characters.
YouTube is serving thumbnails from 2 servers. You just need to replace <YouTube_Video_ID_HERE> with your own YouTube video id. These days webP is best format for fast loading of images due to small image size.
https://img.youtube.com https://i.ytimg.com
Examples are with https://i.ytimg.com server just because it’s shorter, no other particular reason. You can use both.

In Angular RC4 the following works which is a combination of some of the above answers, in your root app.ts add it the providers:
@Component({
templateUrl: 'build/app.html',
providers: [
anotherProvider,
{ provide: Window, useValue: window }
]
})
Then in your service etc inject it into the constructor
constructor(
@Inject(Window) private _window: Window,
)

The PackageInfo.sharedUserId
field will show the user Id assigned in the manifest.
If you want two applications to have the same userId, so they can see each other's data and run in the same process, then assign them the same userId in the manifest:
android:sharedUserId="string"
The two packages with the same sharedUserId need to have the same signature too.
I would also recommend reading here for a nudge in the right direction.
First, the class must implements the click listenener :
implements OnItemClickListener
Then set a listener to the ListView
yourList.setOnItemclickListener(this);
And finally, create the clic method:
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "You Clicked at ",
Toast.LENGTH_SHORT).show();
}
This is in PYSPARK
path="Your file path with file name"
df=spark.read.format("csv").option("header","true").option("inferSchema","true").load(path)
Then you can check
df.show(5)
df.count()
As in other answers, you can just set logging:false
, but I think better than completely disabling logging, you can just embrace log levels in your app. Sometimes you may want to take a look at the executed queries so it may be better to configure Sequelize to log at level verbose or debug. for example (I'm using winston here as a logging framework but you can use any other framework) :
var sequelize = new Sequelize('database', 'username', 'password', {
logging: winston.debug
});
This will output SQL statements only if winston log level is set to debug or lower debugging levels. If log level is warn or info for example SQL will not be logged
You don't need two JScrollPanes
.
Example:
JTextArea ta = new JTextArea();
JScrollPane sp = new JScrollPane(ta);
// Add the scroll pane into the content pane
JFrame f = new JFrame();
f.getContentPane().add(sp);
date('m/d/Y h:i:s a',strtotime($val['EventDateTime']));
there is component ready to use (rc5 compatible)
ng2-steps
which uses Compiler
to inject component to step container
and service for wiring everything together (data sync)
import { Directive , Input, OnInit, Compiler , ViewContainerRef } from '@angular/core';
import { StepsService } from './ng2-steps';
@Directive({
selector:'[ng2-step]'
})
export class StepDirective implements OnInit{
@Input('content') content:any;
@Input('index') index:string;
public instance;
constructor(
private compiler:Compiler,
private viewContainerRef:ViewContainerRef,
private sds:StepsService
){}
ngOnInit(){
//Magic!
this.compiler.compileComponentAsync(this.content).then((cmpFactory)=>{
const injector = this.viewContainerRef.injector;
this.viewContainerRef.createComponent(cmpFactory, 0, injector);
});
}
}
Simply add an extension to the -i flag. This basically creates a backup file with the original file.
sed -i.bakup 's/linenumber/number/' ~/.vimrc
sed will execute without the error
.zip application/zip, application/octet-stream
The top one is a "power" operator, so in this case it is the same as 2 * 2 equal to is 2 to the power of 2. If you put a 3 in the middle position, you will see a difference.
I ran across this issue today working with a clients program. The program works FINE in VS6.0 using the following: (I've changed it slightly)
//
// This is the one include file that every user-written Nextest programs needs.
// Patcom-generated files will also look for this file.
//
#include "stdio.h"
#define IS_NONE( a_key ) ( ( a_key == "none" || a_key == "N/A" ) ? TRUE : FALSE )
//
// Note in my environment we have output() which is printf which adds /n at the end
//
main {
char *psNameNone = "none";
char *psNameNA = "N/A";
char *psNameCAT = "CAT";
if (IS_NONE(psNameNone) ) {
output("psNameNone Matches NONE");
output("%s psNameNoneAddr 0x%x \"none\" addr 0x%X",
psNameNone,psNameNone,
"none");
} else {
output("psNameNone Does Not Match None");
output("%s psNameNoneAddr 0x%x \"none\" addr 0x%X",
psNameNone,psNameNone,
"none");
}
if (IS_NONE(psNameNA) ) {
output("psNameNA Matches N/A");
output("%s psNameNA 0x%x \"N/A\" addr 0x%X",
psNameNA,psNameNA,
"N/A");
} else {
output("psNameNone Does Not Match N/A");
output("%s psNameNA 0x%x \"N/A\" addr 0x%X",
psNameNA,psNameNA,
"N/A");
}
if (IS_NONE(psNameCAT)) {
output("psNameNA Matches CAT");
output("%s psNameNA 0x%x \"CAT\" addr 0x%X",
psNameNone,psNameNone,
"CAT");
} else {
output("psNameNA does not match CAT");
output("%s psNameNA 0x%x \"CAT\" addr 0x%X",
psNameNone,psNameNone,
"CAT");
}
}
If built in VS6.0 with Program Database with Edit and Continue. The compares APPEAR to work. With this setting STRING pooling is enabled, and the compiler optimizes all STRING pointers to POINT TO THE SAME ADDRESSS, so this can work. Any strings created on the fly after compile time will have DIFFERENT addresses so will fail the compare. Changing the setting to Program Database only will build the program so that it will fail.
Building up on Vitaliy Silin's answer. Covering not only cases where we do not want padding at all, but also cases where we have standard size paddings.
See the live conversion of this code to CSS on sassmeister.com
@mixin padding($side, $size) {
$padding-size : 0;
@if $size == 'xs' { $padding-size : 5px; }
@else if $size == 's' { $padding-size : 10px; }
@else if $size == 'm' { $padding-size : 15px; }
@else if $size == 'l' { $padding-size : 20px; }
@if $side == 'all' {
.padding--#{$size} {
padding: $padding-size !important;
}
} @else {
.padding-#{$side}--#{$size} {
padding-#{$side}: $padding-size !important;
}
}
}
$sides-list: all top right bottom left;
$sizes-list: none xs s m l;
@each $current-side in $sides-list {
@each $current-size in $sizes-list {
@include padding($current-side,$current-size);
}
}
This then outputs:
.padding--none {
padding: 0 !important;
}
.padding--xs {
padding: 5px !important;
}
.padding--s {
padding: 10px !important;
}
.padding--m {
padding: 15px !important;
}
.padding--l {
padding: 20px !important;
}
.padding-top--none {
padding-top: 0 !important;
}
.padding-top--xs {
padding-top: 5px !important;
}
.padding-top--s {
padding-top: 10px !important;
}
.padding-top--m {
padding-top: 15px !important;
}
.padding-top--l {
padding-top: 20px !important;
}
.padding-right--none {
padding-right: 0 !important;
}
.padding-right--xs {
padding-right: 5px !important;
}
.padding-right--s {
padding-right: 10px !important;
}
.padding-right--m {

}
.padding-bottom--none {

}
.padding-bottom--xs {
padding-bottom: 5px !important;
}
.padding-bottom--s {
padding-bottom: 10px !important;
}
.padding-bottom--m {
padding-bottom: 15px !important;
}
.padding-bottom--l {

}
.padding-left--none {
padding-left: 0 !important;
}
.padding-left--xs {
padding-left: 5px !important;
}
.padding-left--s {
padding-left: 10px !important;

This worked for me, setting up Googles nameserver because no standard nameserver was specified, followed by restarting networking:
sudo echo "dns-nameservers 8.8.8.8" >> /etc/network/interfaces && sudo ifdown venet0:0 && sudo ifup venet0:0
No multi-line comments in R as of version 2.12 and unlikely to change. In most environments, you can comment blocks by highlighting and toggle-comment. In emacs, this is 'M-x ;'.
I am having the same issue; Intellisense randomly will stop showing in some files, but not others. I just had it happen to me again. Hitting Ctrl + Space won't show anything in Form1
, switching to Form2
or any other class will pop up the list as expected. Restarting Visual Studio usually does the trick, though it's highly annoying and ridiculous for such a basic feature to be broken...
Just for those who want to get $setPristine
without having to upgrade to v1.1.x, here is the function I used to simulate the $setPristine
function. I was reluctant to use the v1.1.5 because one of the AngularUI components I used is no compatible.
var setPristine = function(form) {
if (form.$setPristine) {//only supported from v1.1.x
form.$setPristine();
} else {
/*
*Underscore looping form properties, you can use for loop too like:
*for(var i in form){
* var input = form[i]; ...
*/
_.each(form, function (input) {
if (input.$dirty) {
input.$dirty = false;
}
});
}
};
Note that it ONLY makes $dirty
fields clean and help changing the 'show error' condition like $scope.myForm.myField.$dirty && $scope.myForm.myField.$invalid
.
Other parts of the form object (like the css classes) still need to consider, but this solve my problem: hide error messages.
If you are happy with "blah" in somestring
but want it to be a function/method call, you can probably do this
import operator
if not operator.contains(somestring, "blah"):
continue
All operators in Python can be more or less found in the operator module including in
.
In C++17 we gain the attribute [[maybe_unused]] which is covered in [dcl.attr.unused]
The attribute-token maybe_unused indicates that a name or entity is possibly intentionally unused. It shall appear at most once in each attribute-list and no attribute-argument-clause shall be present. ...
Example:
[[maybe_unused]] void f([[maybe_unused]] bool thing1, [[maybe_unused]] bool thing2) { [[maybe_unused]] bool b = thing1 && thing2; assert(b); }
Implementations should not warn that b is unused, whether or not NDEBUG is defined. —end example ]
For the following example:
int foo ( int bar) {
bool unused_bool ;
return 0;
}
Both clang and gcc generate a diagnostic using -Wall -Wextra for both bar and unused_bool (See it live).
While adding [[maybe_unused]] silences the diagnostics:
int foo ([[maybe_unused]] int bar) {
[[maybe_unused]] bool unused_bool ;
return 0;
}
In C++11 an alternative form of the UNUSED
macro could be formed using a lambda expression(via Ben Deane) with an capture of the unused variable:
#define UNUSED(x) [&x]{}()
The immediate invocation of the lambda expression should be optimized away, given the following example:
int foo (int bar) {
UNUSED(bar) ;
return 0;
}
we can see in godbolt that the call is optimized away:
foo(int):
xorl %eax, %eax
ret

How to cancel AsyncTask
Full answer is here - Android AsyncTask Example
AsyncTask provides a better cancellation strategy, to terminate currently running task.
cancel(boolean mayInterruptIfitRunning)
myTask.cancel(false)- It makes isCancelled returns true. Helps to cancel the task.
myTask.cancel(true) – It also makes isCancelled() returns true, interrupt the background thread and relieves resources .
It is considered as an arrogant way, If there is any thread.sleep() method performing in background thread, cancel(true) will interrupt background thread at that time. But cancel(false) will wait for it and cancel task when that method completes.
If you invoke cancel() and doInBackground() hasn’t begun execute yet. onCancelled() will invoke.
After invoking cancel(…) you should check value returned by isCancelled() on doInbackground() periodically. just like shown below.
protected Object doInBackground(Params… params) {
while (condition)
{
...
if (isCancelled())
break;
}
return null;
}
For Angular 6.1+ , you can use default pipe keyvalue
( Do review and upvote also ) :
<ul>
<li *ngFor="let recipient of map | keyvalue">
{{recipient.key}} --> {{recipient.value}}
</li>
</ul>
For the previous version :
One simple solution to this is convert map to array : Array.from
Component Side :
map = new Map<String, String>();
constructor(){
this.map.set("sss","sss");
this.map.set("aaa","sss");
this.map.set("sass","sss");
this.map.set("xxx","sss");
this.map.set("ss","sss");
this.map.forEach((value: string, key: string) => {
console.log(key, value);
});
}
getKeys(map){
return Array.from(map.keys());
}
Template Side :
<ul>
<li *ngFor="let recipient of getKeys(map)">
{{recipient}}
</li>
</ul>
- Can someone give a simple definition of what
Record
is?
A Record<K, T>
is an object type whose property keys are K
and whose property values are T
. That is, keyof Record<K, T>
is equivalent to K
, and Record<K, T>[K]
is (basically) equivalent to T
.
- Is
Record<K,T>
merely a way of saying "all properties on this object will have typeT
"? Probably not all objects, sinceK
has some purpose...
As you note, K
has a purpose... to limit the property keys to particular values. If you want to accept all possible string-valued keys, you could do something like Record<string, T>
, but the idiomatic way of doing that is to use an index signature like { [k: string]: T }
.
- Does the
K
generic forbid additional keys on the object that are notK
, or does it allow them and just indicate that their properties are not transformed toT
?
It doesn't exactly "forbid" additional keys: after all, a value is generally allowed to have properties not explicitly mentioned in its type... but it wouldn't recognize that such properties exist:
declare const x: Record<"a", string>;
x.b; // error, Property 'b' does not exist on type 'Record<"a", string>'
and it would treat them as excess properties which are sometimes rejected:
declare function acceptR(x: Record<"a", string>): void;
acceptR({a: "hey", b: "you"}); // error, Object literal may only specify known properties
and sometimes accepted:
const y = {a: "hey", b: "you"};
acceptR(y); // okay
With the given example:
type ThreeStringProps = Record<'prop1' | 'prop2' | 'prop3', string>
Is it exactly the same as this?:
type ThreeStringProps = {prop1: string, prop2: string, prop3: string}
Yes!
Hope that helps. Good luck!
Use to_datetime
, there is no need for a format string the parser is man/woman enough to handle it:
In [51]:
pd.to_datetime(df['I_DATE'])
Out[51]:
0 2012-03-28 14:15:00
1 2012-03-28 14:17:28
2 2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]
To access the date/day/time component use the dt
accessor:
In [54]:
df['I_DATE'].dt.date
Out[54]:
0 2012-03-28
1 2012-03-28
2 2012-03-28
dtype: object
In [56]:
df['I_DATE'].dt.time
Out[56]:
0 14:15:00
1 14:17:28
2 14:50:50
dtype: object
You can use strings to filter as an example:
In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]
Out[59]:
date
35 2015-02-05
36 2015-02-06
37 2015-02-07
38 2015-02-08
39 2015-02-09
GnuPG can be used as cross-platform password manager, including GIT HTTPS credetials. Just use your GPG key-pair to encrypt/decrypt passwords(tokens...). To encrypt token(password) run:
gpg -e -o [PATH_TO_ENCRYPTED_TOKEN] -r "[GPG_KEY_USER_ID]"
type the token (or copy-paste it) then press Ctrl+D for ending input, or use file name with this token. Then make custom git credential helper: BASH file with name git-credential-[HELPER_LAST_NAME] (without SH extension):
#!/bin/bash
token=`gpg -d -r "[GPG_KEY_USER_ID]" [PATH_TO_ENCRYPTED_TOKEN] 2>/dev/null`
echo protocol=https
echo host=[YOUR_HOST]
echo username=[YOUR_USER_NAME]
echo password=$token
On MS-WINDOWS in GIT-BASH path names must use UNIX file separator - "/", just run in git-bash "echo $PATH"! Then put the helper into place as in $PATH. Then add and check the helper:
git config --global credential.helper [HELPER_LAST_NAME]
#then check it (password will be printed as plain text!!!):
git credential-[HELPER_LAST_NAME]

Use atof()
or strtof()
* instead:
printf("float value : %4.8f\n" ,atof(s));
printf("float value : %4.8f\n" ,strtof(s, NULL));
http://www.cplusplus.com/reference/clibrary/cstdlib/atof/
http://www.cplusplus.com/reference/cstdlib/strtof/
atoll()
is meant for integers.atof()
/strtof()
is for floats.The reason why you only get 4.00
with atoll()
is because it stops parsing when it finds the first non-digit.
*Note that strtof()
requires C99 or C++11.

You could output them to a .csv file and open the file in excel. Is that direct enough?
is there a smarter way to do this in Python
This hasn't been mentioned, so I'll go ahead - there is a merge stdlib function in the heapq module of python 2.6+. If all you're looking to do is getting things done, this might be a better idea. Of course, if you want to implement your own, the merge of merge-sort is the way to go.
>>> list1 = [1, 5, 8, 10, 50]
>>> list2 = [3, 4, 29, 41, 45, 49]
>>> from heapq import merge
>>> list(merge(list1, list2))
[1, 3, 4, 5, 8, 10, 29, 41, 45, 49, 50]
Here's the documentation.
sys.argv[0]
is not the first argument but the filename of the python program you are currently executing. I think you want sys.argv[1]

For my problem, I removed the #include <glui.h>
statement and it ran without a problem.
Here is my observation. I created a login (readonly) for a group windows(AD) user account but, its acting defiantly in different SQL servers. In the SQl servers that users can not see the databases I added view definition checked and also gave database execute permeation to the master database for avoiding error 229. I do not have this issue if I create a login for a user.
Regarding the triggers breaking NHibernate, I had that experience first-hand. Basically, when NH does an UPDATE it expects certain number of rows affected. By adding SET NOCOUNT ON to the triggers you get the number of rows back to what NH expected thereby fixing the issue. So yeah, I would definitely recommend turning it off for triggers if you use NH.
Regarding the usage in SPs, it's a matter of personal preference. I had always turned the row count off, but then again, there are no real strong arguments either way.
On a different note, you should really consider moving away from SP-based architecture, then you won't even have this question.
If you want to finish and just add a resultCode
(without data), you can call setResult(int resultCode)
before finish()
.
For example:
...
if (everything_OK) {
setResult(Activity.RESULT_OK); // OK! (use whatever code you want)
finish();
}
else {
setResult(Activity.RESULT_CANCELED); // some error ...
finish();
}
...
Then in your calling activity, check the resultCode
, to see if we're OK.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == someCustomRequestCode) {
if (resultCode == Activity.RESULT_OK) {
// OK!
}
else if (resultCode = Activity.RESULT_CANCELED) {
// something went wrong :-(
}
}
}
Don't forget to call the activity with startActivityForResult(intent, someCustomRequestCode)
.

Maybe ICMP packets are blocked by your (mobile) provider. If this code doesn't work on the emulator try to sniff via wireshark or any other sniffer and have a look whats up on the wire when you fire the isReachable() method.
You may also find some info in your device log.

I didn't find this solution here. It removes all of it using the cowplot package:
library(cowplot)
p + theme_nothing() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)
Just noticed that the same thing can be accomplished using theme.void() like this:
p + theme_void() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

I agree with BMSAndroidDroid and Flo-Scheild-Bobby. I was doing a tutorial called DailyQuote and had used the Cordova library. I then changed my OS from Windows to Ubuntu and tried to import projects into Eclipse, (I'm using Eclipse Juno 64-bit, on Ubuntu 12.04 64-bit
, Oracle JDK 7. I also installed the Ubuntu 32-bit libs- so no issues with 64 and 32bit), and got the same issue.
As suggested by Flo-Scheild-Bobby, open configure build path and add the jar(s) again that you added before. Then remove the old jar link(s) and thats it.
If you are accessing the live database by using localhost URL then it will not work. Please deploy your service or website on IIS and create URL and then access the database by using new URL, It will work.

Update the master branch, which you need to do regardless.
Then, one of:
Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.
Merge your branch into master, and resolve the merge conflicts.
Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.
None of these is better than the other, they just have different trade-off patterns.
I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.
To rebase and keep the branch you would:
git checkout <branch> && git rebase <target>
In your case, check out the old branch, then
git rebase master
to get it rebuilt against master.
Use _.map
instead of _.pluck
. In the latest version the _.pluck
has been removed.
LinqToSql will automatically convert a .Skip(N1).Take(N2) into the TSQL syntax for you. In fact, every "query" you do in Linq, is actually just creating a SQL query for you in the background. To test this, just run SQL Profiler while your application is running.
The skip/take methodology has worked very well for me, and others from what I read.
Out of curiosity, what type of self-paging query do you have, that you believe is more efficient than Linq's skip/take?
this works for me:
cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..
Just for the sake of completeness, we can use the operators [
and [[
:
set.seed(1)
df <- data.frame(v1 = runif(10), v2 = letters[1:10])
Several options
df[df[1] < 0.5 | df[2] == "g", ]
df[df[[1]] < 0.5 | df[[2]] == "g", ]
df[df["v1"] < 0.5 | df["v2"] == "g", ]
df$name is equivalent to df[["name", exact = FALSE]]
Using dplyr
:
library(dplyr)
filter(df, v1 < 0.5 | v2 == "g")
Using sqldf
:
library(sqldf)
sqldf('SELECT *
FROM df
WHERE v1 < 0.5 OR v2 = "g"')
Output for the above options:
v1 v2
1 0.26550866 a
2 0.37212390 b
3 0.20168193 e
4 0.94467527 g
5 0.06178627 j
Provide the directory on the command line:
svn checkout file:///home/landonwinters/svn/waterproject/trunk public_html
This won't fix branches that already have the code you don't want in them (see below for how to do that), but if they had pulled some-branch and now want it to be clean (and not "ahead" of origin/some-branch) then you simply:
git checkout some-branch # where some-branch can be replaced by any other branch
git branch base-branch -D # where base-branch is the one with the squashed commits
git checkout -b base-branch origin/base-branch # recreating branch with correct commits
Note: You can combine these all by putting && between them
Note2: Florian mentioned this in a comment, but who reads comments when looking for answers?
Note3: If you have contaminated branches, you can create new ones based off the new "dumb branch" and just cherry-pick commits over.
Ex:
git checkout feature-old # some branch with the extra commits
git log # gives commits (write down the id of the ones you want)
git checkout base-branch # after you have already cleaned your local copy of it as above
git checkout -b feature-new # make a new branch for your feature
git cherry-pick asdfasd # where asdfasd is one of the commit ids you want
# repeat previous step for each commit id
git branch feature-old -D # delete the old branch
Now feature-new is your branch without the extra (possibly bad) commits!
The Python docs say all that needs to be said, as far as I can see.
setattr
(object, name, value)This is the counterpart of
getattr()
. The arguments are an object, a string and an arbitrary value. The string may name an existing attribute or a new attribute. The function assigns the value to the attribute, provided the object allows it. For example,setattr(x, 'foobar', 123)
is equivalent tox.foobar = 123
.
If this isn't enough, explain what you don't understand.
Since there's no mention of how to compile a .c file together with a bunch of .o files, and this comment asks for it:
where's the main.c in this answer? :/ if file1.c is the main, how do you link it with other already compiled .o files? – Tom Brito Oct 12 '14 at 19:45
$ gcc main.c lib_obj1.o lib_obj2.o lib_objN.o -o x0rbin
Here, main.c is the C file with the main() function and the object files (*.o) are precompiled. GCC knows how to handle these together, and invokes the linker accordingly and results in a final executable, which in our case is x0rbin.
You will be able to use functions not defined in the main.c but using an extern reference to functions defined in the object files (*.o).
You can also link with .obj or other extensions if the object files have the correct format (such as COFF).
You can implement it using View.scrollTo(..) also.
postDelayed(new Runnable() {
public void run() {
counter = (int) (counter + 10);
handler.postDelayed(this, 100);
llParent.scrollTo(counter , 0);
}
}
}, 1000L);
The Application.Volatile
doesn't work for recalculating a formula with my own function inside. I use the following function:
Application.CalculateFull
<HTML>
<HEAD>
<TITLE>Sum</TITLE>
<script type="text/javascript">
function sum()
{
var num1 = document.myform.number1.value;
var num2 = document.myform.number2.value;
var sum = parseInt(num1) + parseInt(num2);
document.getElementById('add').value = sum;
}
</script>
</HEAD>
<BODY>
<FORM NAME="myform">
<INPUT TYPE="text" NAME="number1" VALUE=""/> +
<INPUT TYPE="text" NAME="number2" VALUE=""/>
<INPUT TYPE="button" NAME="button" Value="=" onClick="sum()"/>
<INPUT TYPE="text" ID="add" NAME="result" VALUE=""/>
</FORM>
</BODY>
</HTML>
This should work properly. 1. use .value instead of "innerHTML" when setting the 3rd field (input field) 2. Close the input tags
You can use COLLATE NOCASE
in your SELECT
query:
SELECT * FROM ... WHERE name = 'someone' COLLATE NOCASE
Additionaly, in SQLite, you can indicate that a column should be case insensitive when you create the table by specifying collate nocase
in the column definition (the other options are binary
(the default) and rtrim
; see here). You can specify collate nocase
when you create an index as well. For example:
create table Test ( Text_Value text collate nocase ); insert into Test values ('A'); insert into Test values ('b'); insert into Test values ('C'); create index Test_Text_Value_Index on Test (Text_Value collate nocase);
Expressions involving Test.Text_Value
should now be case insensitive. For example:
sqlite> select Text_Value from Test where Text_Value = 'B'; Text_Value ---------------- b sqlite> select Text_Value from Test order by Text_Value; Text_Value ---------------- A b C sqlite> select Text_Value from Test order by Text_Value desc; Text_Value ---------------- C b A
The optimiser can also potentially make use of the index for case-insensitive searching and matching on the column. You can check this using the explain
SQL command, e.g.:
sqlite> explain select Text_Value from Test where Text_Value = 'b'; addr opcode p1 p2 p3 ---------------- -------------- ---------- ---------- --------------------------------- 0 Goto 0 16 1 Integer 0 0 2 OpenRead 1 3 keyinfo(1,NOCASE) 3 SetNumColumns 1 2 4 String8 0 0 b 5 IsNull -1 14 6 MakeRecord 1 0 a 7 MemStore 0 0 8 MoveGe 1 14 9 MemLoad 0 0 10 IdxGE 1 14 + 11 Column 1 0 12 Callback 1 0 13 Next 1 9 14 Close 1 0 15 Halt 0 0 16 Transaction 0 0 17 VerifyCookie 0 4 18 Goto 0 1 19 Noop 0 0
Update-Package -ProjectName 'YourProjectNameGoesHere' -Reinstall
This is best and easiest example I found. It will reinstall all nugets that are listed in packages.config and it will preserve current versions. Replace YourProjectNameGoesHere
with the project name.
That syntax should work OK, but you can try this alternative.
<a href="javascript:void(0);" onclick="ShowOld(2367,146986,2);">
or
<a href="javascript:ShowOld(2367, 146986, 2);">
UPDATED ANSWER FOR STRING VALUES
If you are passing strings, use single quotes for your function's parameters
<a href="javascript:ShowOld('foo', 146986, 'bar');">
In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic
about following the C++ standard), you can do:
int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++
If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:
int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!
Or, better yet, use a standard container:
int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>
If you still want a proper array, you can use a constant, not a variable, when creating it:
const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)
Similarly, if you want to get the size from a function in C++11, you can use a constexpr
:
constexpr int n()
{
return 10;
}
double a[n()]; // n() is a compile time constant expression
The problem you're having is that the output you get into the variable 's' is not a csv, but a html file. In order to get the raw csv, you have to modify the url to:
'https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv'
Your second problem is that read_csv expects a file name, we can solve this by using StringIO from io module. Third problem is that request.get(url).content delivers a byte stream, we can solve this using the request.get(url).text instead.
End result is this code:
from io import StringIO
import pandas as pd
import requests
url='https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv'
s=requests.get(url).text
c=pd.read_csv(StringIO(s))
output:
>>> c.head()

Clearly, there is no perfect answer. However, if you want to allow the user to
then the easiest way seems to be to move the focus off the selected cell, so that clicking it will trigger a Select event.
One option is to move the focus as I suggested above, but this prevents cell editing. Another option is to extend the selection by one cell (left/right/up/down),because this permits editing of the original cell, but will trigger a Select event if that cell is clicked again on its own.
If you only wanted to trap selection of a single column of cells, you could insert a hidden column to the right, extend the selection to include the hidden cell to the right when the user clicked,and this gives you an editable cell which can be trapped every time it is clicked. The code is as follows
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'prevent Select event triggering again when we extend the selection below
Application.EnableEvents = False
Target.Resize(1, 2).Select
Application.EnableEvents = True
End Sub
You will need to create an instance of a new window like so.
var window2 = new Window2();
Once you have the instance you can use the Show() or ShowDialog() method depending on what you want to do.
window2.Show();
or
var result = window2.ShowDialog();
ShowDialog() will return a Nullable<bool>
if you need that.
Imao put UIImageView on background is not the best idea . In my case i added on controller view other 2 views . First view has [UIColor clearColor]
on background, second - color which u want to be transparent (grey in my case).Note that order is important.Then for second view set alpha 0.5(alpha >=0 <=1).Added this to lines in prepareForSegue
infoVC.providesPresentationContextTransitionStyle = YES;
infoVC.definesPresentationContext = YES;
And thats all.
interestingly, in C# you have the keyword const that translates to C++'s static const, as opposed to readonly which can be only set at constructors and initializations, even by non-constants, ex:
readonly DateTime a = DateTime.Now;
I agree, if you have a const pre-defined array you might as well make it static. At that point you can use this interesting syntax:
//in header file
class a{
static const int SIZE;
static const char array[][10];
};
//in cpp file:
const int a::SIZE = 5;
const char array[SIZE][10] = {"hello", "cruel","world","goodbye", "!"};
however, I did not find a way around the constant '10'. The reason is clear though, it needs it to know how to perform accessing to the array. A possible alternative is to use #define, but I dislike that method and I #undef at the end of the header, with a comment to edit there at CPP as well in case if a change.
If you need to set default value and your form relates to the entity, then you should use following approach:
// buildForm() method
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
...
->add(
'myField',
'text',
array(
'data' => isset($options['data']) ? $options['data']->getMyField() : 'my default value'
)
);
}
Otherwise, myField
always will be set to default value, instead of getting value from entity.
Extending @oopbase's answer with return;
statement.
Let's consider a use case of traditional authentication system where we store login information into the session. On each page we check for active session like,
/* Some Import Statements here. */
if(null == session || !session.getAttribute("is_login").equals("1")) {
response.sendRedirect("http://domain.com/login");
}
// ....
session.getAttribute("user_id");
// ....
/* Some More JSP+Java+HTML code here */
It looks fine at first glance however; It has one issue. If your server has expired session due to time limit and user is trying to access the page he might get error if you have not written your code in try..catch
block or handled if(null != session.getAttribute("attr_name"))
everytime.
So by putting a return;
statement I stopped further execution and forced to redirect page to certain location.
if(null == session || !session.getAttribute("is_login").equals("1")) {
response.sendRedirect("http://domain.com/login");
return;
}
Note that Use of redirection may vary based on the requirements. Nowadays people don't use such authentication system. (Modern approach - Token Based Authentication) It's just an simple example to understand where and how to place redirection(s).

position: absolute
will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static
.
Have your four divs nested inside the target div, give the target div position: relative
, and use position: absolute
on the others.
Structure your HTML similar to this:
<div id="container">
<div class="top left"></div>
<div class="top right"></div>
<div class="bottom left"></div>
<div class="bottom right"></div>
</div>
And this CSS should work:
#container {

Active directory is a directory service provider, where you can add new user to a directory, remove or modify, specify privilages, assign policy etc. Its just like a phone directory where every person have a unique contact number. Every thing in AD(Active Directory) are considered as Objects and every object is given a Unique ID.(similar to a unique contact number in a phone directory.
Ldap is a protocol specially designed for directory service providers. Windows server OS uses AD as a directory server, AIX which is a UNIX version by IBM uses Tivoli directory server. Both of them uses LDAP protocol for interacting with directory.
Apart from protocol there are LDAP servers, LDAP browsers too.
There is Prometheus GPU Metrics Exporter (PGME) that leverages the nvidai-smi binary. You may try this out. Once you have the exporter running, you can access it via http://localhost:9101/metrics. For two GPUs, the sample result looks like this:
temperature_gpu{gpu="TITAN X (Pascal)[0]"} 41
utilization_gpu{gpu="TITAN X (Pascal)[0]"} 0
utilization_memory{gpu="TITAN X (Pascal)[0]"} 0
memory_total{gpu="TITAN X (Pascal)[0]"} 12189
memory_free{gpu="TITAN X (Pascal)[0]"} 12189
memory_used{gpu="TITAN X (Pascal)[0]"} 0
temperature_gpu{gpu="TITAN X (Pascal)[1]"} 78
utilization_gpu{gpu="TITAN X (Pascal)[1]"} 95
utilization_memory{gpu="TITAN X (Pascal)[1]"} 59
memory_total{gpu="TITAN X (Pascal)[1]"} 12189
memory_free{gpu="TITAN X (Pascal)[1]"} 1738
memory_used{gpu="TITAN X (Pascal)[1]"} 10451
I have to add BINARY to the ColumnX, to get result as case sensitive
SELECT * FROM MyTable WHERE BINARY(ColumnX) REGEXP '^[a-z]';
There are some good answers here, but I wanted to point out a couple of other things. Function parameters are actually a place where PowerShell shines. For example, you can have either named or positional parameters in advanced functions like so:
function Get-Something
{
Param
(
[Parameter(Mandatory=$true, Position=0)]
[string] $Name,
[Parameter(Mandatory=$true, Position=1)]
[int] $Id
)
}
Then you could either call it by specifying the parameter name, or you could just use positional parameters, since you explicitly defined them. So either of these would work:
Get-Something -Id 34 -Name "Blah"
Get-Something "Blah" 34
The first example works even though Name
is provided second, because we explicitly used the parameter name. The second example works based on position though, so Name
would need to be first. When possible, I always try to define positions so both options are available.
PowerShell also has the ability to define parameter sets. It uses this in place of method overloading, and again is quite useful:
function Get-Something
{
[CmdletBinding(DefaultParameterSetName='Name')]
Param
(
[Parameter(Mandatory=$true, Position=0, ParameterSetName='Name')]
[string] $Name,
[Parameter(Mandatory=$true, Position=0, ParameterSetName='Id')]
[int] $Id
)
}
Now the function will either take a name, or an id, but not both. You can use them positionally, or by name. Since they are a different type, PowerShell will figure it out. So all of these would work:
Get-Something "some name"
Get-Something 23
Get-Something -Name "some name"
Get-Something -Id 23
You can also assign additional parameters to the various parameter sets. (That was a pretty basic example obviously.) Inside of the function, you can determine which parameter set was used with the $PsCmdlet.ParameterSetName property. For example:
if($PsCmdlet.ParameterSetName -eq "Name")
{
Write-Host "Doing something with name here"
}
Then, on a related side note, there is also parameter validation in PowerShell. This is one of my favorite PowerShell features, and it makes the code inside your functions very clean. There are numerous validations you can use. A couple of examples are:
function Get-Something
{
Param
(
[Parameter(Mandatory=$true, Position=0)]
[ValidatePattern('^Some.*')]
[string] $Name,
[Parameter(Mandatory=$true, Position=1)]
[ValidateRange(10,100)]
[int] $Id
)
}
In the first example, ValidatePattern accepts a regular expression that assures the supplied parameter matches what you're expecting. If it doesn't, an intuitive exception is thrown, telling you exactly what is wrong. So in that example, 'Something' would work fine, but 'Summer' wouldn't pass validation.
ValidateRange ensures that the parameter value is in between the range you expect for an integer. So 10 or 99 would work, but 101 would throw an exception.
Another useful one is ValidateSet, which allows you to explicitly define an array of acceptable values. If something else is entered, an exception will be thrown. There are others as well, but probably the most useful one is ValidateScript. This takes a script block that must evaluate to $true, so the sky is the limit. For example:
function Get-Something
{
Param
(
[Parameter(Mandatory=$true, Position=0)]
[ValidateScript({ Test-Path $_ -PathType 'Leaf' })]
[ValidateScript({ (Get-Item $_ | select -Expand Extension) -eq ".csv" })]
[string] $Path
)
}
In this example, we are assured not only that $Path exists, but that it is a file, (as opposed to a directory) and has a .csv extension. ($_ refers to the parameter, when inside your scriptblock.) You can also pass in much larger, multi-line script blocks if that level is required, or use multiple scriptblocks like I did here. It's extremely useful and makes for nice clean functions and intuitive exceptions.
Something more to the point for me..
var jsontext = '{"firstname":"Jesper","surname":"Aaberg","phone":["555-0100","555-0120"]}';
var contact = JSON.parse(jsontext);
document.write(contact.surname + ", " + contact.firstname);
document.write(contact.phone[1]);
// Output:
// Aaberg, Jesper
// 555-0100

Visual Studio 2008 does have a designer that allows you to add FK's. Just right-click the table... Table Properties, then go to the "Add Relations" section.
based on Wesley Coetzee's answer i wrote this. Hope it can help anyone googling this issue. I had bugs with swapping the paginator size in the middle of the list that's why i submit my answer:
Paginator html and list
<mat-paginator [length]="localNewspapers.length" pageSize=20
(page)="getPaginatorData($event)" [pageSizeOptions]="[10, 20, 30]"
showFirstLastButtons="false">
</mat-paginator>
<mat-list>
<app-newspaper-pagi-item *ngFor="let paper of (localNewspapers |
slice: lowValue : highValue)"
[newspaper]="paper">
</app-newspaper-pagi-item>
Component logic
import {Component, Input, OnInit} from "@angular/core";
import {PageEvent} from "@angular/material";
@Component({
selector: 'app-uniques-newspaper-list',
templateUrl: './newspaper-uniques-list.component.html',
})
export class NewspaperUniquesListComponent implements OnInit {
lowValue: number = 0;
highValue: number = 20;
// used to build an array of papers relevant at any given time
public getPaginatorData(event: PageEvent): PageEvent {
this.lowValue = event.pageIndex * event.pageSize;
this.highValue = this.lowValue + event.pageSize;
return event;
}
}
You can use the nm -g
tool from the binutils toolchain. However, their source is not always readily available. and I'm not actually even sure that this information can always be retrieved. Perhaps objcopy
reveals further information.
/EDIT: The tool's name is of course nm
. The flag -g
is used to show only exported symbols.
This is another method . Passing array as a pointer to the function
void generateArray(int *array, int size) {
srand(time(0));
for (int j=0;j<size;j++)
array[j]=(0+rand()%9);
}
int main(){
const int size=5;
int a[size];
generateArray(a, size);
return 0;
}
Object doesn't support this property or method.
Think of it like if anything after the dot is called on an object. It's like a chain.
An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot .
you get intelli-sense (that white dropdown) trying to help you pick the correct action.
(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)
Type this much anywhere in your code area
Dim a As Worksheets
a.
you get help from VBE, it's a little dropdown called Intelli-sense
It lists all available actions that particular object exposes to any user. You can't see the .Selection
member of the Worksheets()
class. That's what the error tells you exactly.
Object doesn't support this property or method.
If you look at the example on MSDN
Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count
It activates
the sheet first then calls the Selection...
it's not connected together because Selection
is not a member of Worksheets()
class. Simply, you can't prefix the Selection
What about
Sub DisplayColumnCount()
Dim iAreaCount As Integer
Dim i As Integer
Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count
If iAreaCount <= 1 Then
MsgBox "The selection contains " & Selection.Columns.Count & " columns."
Else
For i = 1 To iAreaCount
MsgBox "Area " & i & " of the selection contains " & _
Selection.Areas(i).Columns.Count & " columns."
Next i
End If
End Sub

Try this:
window.open(url, '_blank');
This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

I think this example is self explanatory. It runs the method of first parameter, whose name is given in the second parameter.
class MyClass:
def __init__(self):
pass
def MyMethod(self):
print("Method ran")
# Create an object
object = MyClass()
# Get all the methods of a class
method_list = [func for func in dir(MyClass) if callable(getattr(MyClass, func))]
# You can use any of the methods in method_list
# "MyMethod" is the one we want to use right now
# This is the same as running "object.MyMethod()"
getattr(object,'MyMethod')()
The below code works fine but I am not sure about the radio button and dropdown list
$( '#form_id' ).submit( function( event ) {
event.preventDefault();
//validate fields
var fail = false;
var fail_log = '';
var name;
$( '#form_id' ).find( 'select, textarea, input' ).each(function(){
if( ! $( this ).prop( 'required' )){
} else {
if ( ! $( this ).val() ) {
fail = true;
name = $( this ).attr( 'name' );
fail_log += name + " is required \n";
}
}
});
//submit if fail never got set to true
if ( ! fail ) {
//process form here.
} else {
alert( fail_log );
}
});
here is the one working fine:

I faced the same bug as below. Then I fixed it as below:
dotnet ef migrations list
dotnet ef migrations remove
4.Now it is fine. Try to re-add:
dotnet ef migrations add [new_dbo_name]
5.Finally, try to update again, in arrangement base on migration list:
dotnet ef database update [First]
dotnet ef database update [Second]
dotnet ef database update [new_dbo_name]
Hope it is helpful for you. ^^
I was having a similar issue with my very first java program.
I was issuing this command
java HelloWorld.class
Which resulted in the same error.
Turns out you need to exclude the .class

Assuming your row number is in B1
, you can use INDIRECT
:
=INDIRECT("A" & B1)
This takes a cell reference as a string (in this case, the concatenation of A
and the value of B1
- 5), and returns the value at that cell.
TS gets compiled to JS which then executed. Therefore you have access to all of the objects in the JS runtime. One of those objects is the JSON
object. This contains the following methods:
JSON.parse()
method parses a JSON string, constructing the JavaScript value or object described by the string.JSON.stringify()
method converts a JavaScript object or value to a JSON string.Example:
const jsonString = '{"employee":{ "name":"John", "age":30, "city":"New York" }}';_x000D_
_x000D_
_x000D_
const JSobj = JSON.parse(jsonString);_x000D_
_x000D_
console.log(JSobj);_x000D_
console.log(typeof JSobj);_x000D_
_x000D_
const JSON_string = JSON.stringify(JSobj);_x000D_
_x000D_
console.log(JSON_string);_x000D_
console.log(typeof JSON_string);

"Server not found in Kerberos database" error can happen if you have registered the SPN to multiple users/computers.
You can check that with:
