I use different predefined colors like so:
theme = {
whateverFlashColor: '#ffffaa',
whateverElseFlashColor: '#bbffaa',
whateverElseThenFlashColor: '#ffffff',
};
and use them like this
$('#element').effect("highlight", {color:theme.whateverFlashColor}, 1000);
easy :)
All answers here are correct when it comes to the ::selection
pseudo element, and how it works. However, the question does in fact specifically ask how to use it on text inputs.
The only way to do that is to apply the rule via a parent of the input (any parent for that matter):
.parent ::-webkit-selection, [contenteditable]::-webkit-selection {_x000D_
background: #ffb7b7;_x000D_
}_x000D_
_x000D_
.parent ::-moz-selection, [contenteditable]::-moz-selection {_x000D_
background: #ffb7b7;_x000D_
}_x000D_
_x000D_
.parent ::selection, [contenteditable]::selection {_x000D_
background: #ffb7b7;_x000D_
}_x000D_
_x000D_
/* Aesthetics */_x000D_
input, [contenteditable] {_x000D_
border:1px solid black;_x000D_
display:inline-block;_x000D_
width: 150px;_x000D_
height: 20px;_x000D_
line-height: 20px;_x000D_
padding: 3px;_x000D_
}
_x000D_
<span class="parent"><input type="text" value="Input" /></span>_x000D_
<span contenteditable>Content Editable</span>
_x000D_
You can use the listings package. It supports many different languages and there are lots of options for customising the output.
\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[language=html]
<html>
<head>
<title>Hello</title>
</head>
<body>Hello</body>
</html>
\end{lstlisting}
\end{document}
I think mixing @ShaunBouckaert and Mar 19 '09 at 16:22 answers is a good compromise :
" Reset highlighted search
nnoremap <CR> :let @/=""<CR><CR>
Press Enter and the highlighted text is no longer highlighted, while search highlighting is still enabled.
You can use the jQuery Color plugin.
For example, to draw attention to all the divs on your page, you could use the following code:
$("div").stop().css("background-color", "#FFFF9C")
.animate({ backgroundColor: "#FFFFFF"}, 1500);
Edit - New and improved
The following uses the same technique as above, but it has the added benefits of:
Extend the jQuery Object:
var notLocked = true;
$.fn.animateHighlight = function(highlightColor, duration) {
var highlightBg = highlightColor || "#FFFF9C";
var animateMs = duration || 1500;
var originalBg = this.css("backgroundColor");
if (notLocked) {
notLocked = false;
this.stop().css("background-color", highlightBg)
.animate({backgroundColor: originalBg}, animateMs);
setTimeout( function() { notLocked = true; }, animateMs);
}
};
Usage example:
$("div").animateHighlight("#dd0000", 1000);
To highlight a block of code in Notepad++, please do the following steps
Style token
and select any of the five choices available ( styles from Using 1st style
to using 5th style
). Each is of different colors.If you want yellow color choose using 3rd style
.If you want to create your own style you can use Style Configurator
under Settings
menu.
Append the following line to the end of your .vimrc
to prevent highlighting altogether:
set nohlsearch
For Internet Explorer in addition, you need to add pseudo class focus
(.ClassName:focus) and outline-style: none
.
.ClassName,
.ClassName:focus {
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
outline-style: none; /* Internet Explorer */
}
font is deprecated use span instead Html.fromHtml("<span style=color:red>"+content+"</span>")
It seems to me that you need current code as this ".menu-current css", I am asking the same code that works like a charm, You could try something like this might still be some configuration
a:link, a:active {
color: blue;
text-decoration: none;
}
a:visited {
color: darkblue;
text-decoration: none;
}
a:hover {
color: blue;
text-decoration: underline;
}
div.menuv {
float: left;
width: 10em;
padding: 1em;
font-size: small;
}
div.menuv ul, div.menuv li, div.menuv .menuv-current li {
margin: 0;
padding: 0;
list-style: none;
margin-bottom: 5px;
font-weight: normal;
}
div.menuv ul ul {
padding-left: 12px;
}
div.menuv a:link, div.menuv a:visited, div.menuv a:active, div.menuv a:hover {
display: block;
text-decoration: none;
padding: 2px 2px 2px 3px;
border-bottom: 1px dotted #999999;
}
div.menuv a:hover, div.menuv .menuv-current li a:hover {
padding: 2px 0px 2px 1px;
border-left: 2px solid green;
border-right: 2px solid green;
}
div.menuv .menuv-current {
font-weight: bold;
}
div.menuv .menuv-current a:hover {
padding: 2px 2px 2px 3px;
border-left: none;
border-right: none;
border-bottom: 1px dotted #999999;
color: darkblue;
}
No, that's not how it is done. Normal way to initialize the base class is in the initialization list :
class A
{
public:
A(int val) {}
};
class B : public A
{
public:
B( int v) : A( v )
{
}
};
void main()
{
B b(10);
}
You can use the .not()
method or :not()
selector
Code based on your example:
$("ul#list li").not(".active") // not method
$("ul#list li:not(.active)") // not selector
''.join([a, b]) is better solution than +.
Because Code should be written in a way that does not disadvantage other implementations of Python (PyPy, Jython, IronPython, Cython, Psyco, and such)
form a += b or a = a + b is fragile even in CPython and isn't present at all in implementations that don't use refcounting (reference counting is a technique of storing the number of references, pointers, or handles to a resource such as an object, block of memory, disk space or other resource)
https://www.python.org/dev/peps/pep-0008/#programming-recommendations
This should work:
ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")
This article by Andre Staltz is the best and clearest explanation I've seen so far.
Some quotes from the article:
Reactive programming is programming with asynchronous data streams.
On top of that, you are given an amazing toolbox of functions to combine, create and filter any of those streams.
Here's an example of the fantastic diagrams that are a part of the article:
Adding to the answers above -
To use in a script, use the following :-
result=`ps aux | grep -i "myscript.sh" | grep -v "grep" | wc -l`
if [ $result -ge 1 ]
then
echo "script is running"
else
echo "script is not running"
fi
Use the @Input() decorator in your child component to allow the parent to bind to this input.
In the child component you declare it as is :
@Input() myInputName: myType
To bind a property from parent to a child you must add in you template the binding brackets and the name of your input between them.
Example :
<my-child-component [myChildInputName]="myParentVar"></my-child-component>
But beware, objects are passed as a reference, so if the object is updated in the child the parent's var will be too updated. This might lead to some unwanted behaviour sometime. With primary types the value is copied.
To go further read this :
Docs : https://angular.io/docs/ts/latest/cookbook/component-communication.html
You can find an example and the technical reason to why it is not allowed in @stefan 's answer. Now a logical answer to this question according to me is:
The major use of virtual keyword is to enable polymorphic behaviour when we don't know what type of the object the base class pointer will point to.
But think of this is more primitive way, for using virtual functionality you will require a pointer. And what does a pointer require? An object to point to! (considering case for correct execution of the program)
So, we basically require an object that already exists somewhere in the memory (we are not concerned with how the memory was allocated, it may be at compile time or either runtime) so that our pointer can correctly point to that object.
Now, think of the situation about the moment when the object of the class to be pointed is being assigned some memory -> Its constructor will be called automatically at that instance itself!
So we can see that we don't actually need to worry about the constructor being virtual, because in any of the cases you wish to use a polymorphic behaviour our constructor would have already been executed making our object ready for usage!
jspdf does not work with css but it can work along with html2canvas. You can use jspdf along with html2canvas.
include these two files in script on your page :
<script type="text/javascript" src="html2canvas.js"></script>
<script type="text/javascript" src="jspdf.min.js"></script>
<script type="text/javascript">
function genPDF()
{
html2canvas(document.body,{
onrendered:function(canvas){
var img=canvas.toDataURL("image/png");
var doc = new jsPDF();
doc.addImage(img,'JPEG',20,20);
doc.save('test.pdf');
}
});
}
</script>
You need to download script files such as https://github.com/niklasvh/html2canvas/releases https://cdnjs.com/libraries/jspdf
make clickable button on page so that it will generate pdf and it will be seen same as that of original html page.
<a href="javascript:genPDF()">Download PDF</a>
It will work perfectly.
Using [Authorize]
attributes can help prevent security holes in your application. The way that MVC handles URL's (i.e. routing them to a controller rather than to an actual file) makes it difficult to actually secure everything via the web.config file.

(I'm using React Native; targetSdkVersion 22). I'm trying to change the look of a calendar date picker dialog. The accepted answer didn't work for me, but this did. Hope this snippet helps some of you.
<style name="CalendarDatePickerDialog" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">#6bf442</item>
<item name="android:textColorPrimary">#6bf442</item>

Easiest is still
import sys
total_records = 1000
for i in range (total_records):
sys.stdout.write('\rUpdated record: ' + str(i) + ' of ' + str(total_records))
sys.stdout.flush()
Key is to convert the integer type to string.
A very simple check that you can do:
Explanation 1:
if (value) {
// it will come inside
// If value is either undefined, null or ''(empty string)
}
Explanation 2:
(!value) ? "Case 1" : "Case 2"
If the value is either undefined , null or '' then Case 1 otherwise for any other value of value Case 2.

You are not passing the variable correctly. One fast solution is to make a global variable like this:
var global_json_data;
$(document).ready(function() {
var json_source = "https://spreadsheets.google.com/feeds/list/0ApL1zT2P00q5dG1wOUMzSlNVV3VRV2pwQ2Fnbmt3M0E/od7/public/basic?alt=json";
var string_data ="";
var json_data = $.ajax({
dataType: 'json', // Return JSON
url: json_source,
success: function(data){
var data_obj = [];
for (i=0; i<data.feed.entry.length; i++){
var el = {'key': data.feed.entry[i].title['$t'], 'value': '<p><a href="'+data.feed.entry[i].content['$t']+'>'+data.feed.entry[i].title['$t']+'</a></p>'};
data_obj.push(el)};
console.log("data grabbed");
global_json_data = data_obj;
return data_obj;
},
error: function(jqXHR, textStatus, errorThrown){
$('#results_box').html('<h2>Something went wrong!</h2><p><b>' + textStatus + '</b> ' + errorThrown + '</p>');
}
});
$(':submit').click(function(event){
var json_data = global_json_data;
event.preventDefault();
console.log(json_data.length);
//function
if ($('#place').val() !=''){
var copy_string = $('#place').val();
var converted_string = copy_string;
for (i=0; i<json_data.length; i++){
//console_log(data.feed.entry[i].title['$t']);
converted_string = converted_string.replace(json_data.feed.entry[i].title['$t'],
'<a href="'+json_data.feed.entry[i].content['$t']+'>'+json_data.feed.entry[i].title['$t']+'</a>');
}
$('#results_box').text(converted_string).html();
}
});
});//document ready end
Imo, the best way to parse your JSON response with GSON would be creating classes that "match" your response and then use Gson.fromJson()
method.
For example:
class Response {
Map<String, App> descriptor;
// standard getters & setters...
}
class App {
String name;
int age;
String[] messages;
// standard getters & setters...
}
Then just use:
Gson gson = new Gson();
Response response = gson.fromJson(yourJson, Response.class);
Where yourJson
can be a String
, any Reader
, a JsonReader
or a JsonElement
.
Finally, if you want to access any particular field, you just have to do:
String name = response.getDescriptor().get("app3").getName();
You can always parse the JSON manually as suggested in other answers, but personally I think this approach is clearer, more maintainable in long term and it fits better with the whole idea of JSON.
Borrowing from tennisgent's answer. I like that you don't have to create a custom directive to add on all the links. However, I couldnt get his to work in IE8. Here's what finally worked for me (using angular 1.0.6).
Notice that 'bind' allows you to use jqLite provided by angular so no need to wrap with full jQuery. Also required the stopPropogation method.
.directive('a', [
function() {
return {
restrict: 'E',
link: function(scope, elem, attrs) {
elem.bind('click', function(e){
if (attrs.ngClick || attrs.href === '' || attrs.href == '#'){
e.preventDefault();
e.stopPropagation();
}
})
}
};
}
])
Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like
INSERT INTO HISTORICAL_CAR_STATS (
HISTORICAL_CAR_STATS_ID,
YEAR,
MONTH,
MAKE,
MODEL,
REGION,
AVG_MSRP,
CNT)
SELECT MY_SEQ.nextval,
year,
month,
make,
model,
region,
avg_msrp,
cnt
FROM (SELECT '2010' year,
'12' month,
'ALL' make,
'ALL' model,
REGION,
sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
sum(cnt) cnt
FROM HISTORICAL_CAR_STATS
WHERE YEAR = '2010'
AND MONTH = '12'
AND MAKE != 'ALL'
GROUP BY REGION)
You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder. You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.
I fixed this by removing an "excluding" attribute for that package in my .classpath
file. Remove the attribute, not the whole tag, or "src/java" will cease to be a source folder.
<classpathentry excluding="com/myproject/mypackage/mysubpackage/" kind="src" path="src/java"/>
Hovercraft Full Of Eels' answer is very good, but i had to change it a bit in order to get it working on my program:
int y1 = (int) ((this.height - 2 * BORDER_GAP) - (values.get(i) * yScale - BORDER_GAP));
instead of
int y1 = (int) (scores.get(i) * yScale + BORDER_GAP);
because if i used his way the graphic would be upside down
(you'd see it if you used hardcoded values (e.g 1,3,5,7,9) instead of random values)
I had also problem with git, that used to "steal" my cygwin commands - so i needed to run
C:\cygwin\bin\mintty.exe -
but after installing chere
and executing chere -i -t mintty -f
as admin (see above), you can simply use :
C:\cygwin\bin\mintty.exe -e /bin/xhere /bin/bash.exe "."
I added this in Total Commander as custom button (right click on panel > add ...) and it works very well.
As a side note, Gecko and WebKit support the the
text-rendering
property as well.
You can use contextual selectors and move the vertical-align there. This would work with the p tag, then. Take this snippet below as an example. Any p tags within your class will respect the vertical-align control:
#header_selecttxt {
font-family: Arial;
font-size: 12px;
font-weight: bold;
}
#header_selecttxt p {
vertical-align: text-top;
}
You could also keep the vertical-align in both sections so that other, inline elements would use this.
This should help you.
* {
margin: 0;
}
html, body {

.wrapper {
min-height: 100%;
height: auto !important;

margin: 0 auto -155px; /* the bottom margin is the negative value of the footer's height */
}
.footer {
height: 155px;
}
Here's extension method to convert DataTable to object list:
public static class Extensions
{
public static List<T> ToList<T>(this DataTable table) where T : new()
{
IList<PropertyInfo> properties = typeof(T).GetProperties().ToList();
List<T> result = new List<T>();
foreach (var row in table.Rows)
{
var item = CreateItemFromRow<T>((DataRow)row, properties);
result.Add(item);
}
return result;
}
private static T CreateItemFromRow<T>(DataRow row, IList<PropertyInfo> properties) where T : new()
{
T item = new T();
foreach (var property in properties)
{
if (property.PropertyType == typeof(System.DayOfWeek))
{
DayOfWeek day = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), row[property.Name].ToString());
property.SetValue(item,day,null);
}
else
{
if(row[property.Name] == DBNull.Value)
property.SetValue(item, null, null);
else
property.SetValue(item, row[property.Name], null);
}
}
return item;
}
}
usage:
List<Employee> lst = ds.Tables[0].ToList<Employee>();
@itay.b
CODE EXPLAINED:
We first read all the property names from the class T using reflection
then we iterate through all the rows in datatable and create new object of T,
then we set the properties of the newly created object using reflection.
The property values are picked from the row's matching column cell.
PS: class property name and table column names must be same
var filtered = projects;
foreach (var tag in filteredTags) {
filtered = filtered.Where(p => p.Tags.Contains(tag))
}
The nice thing with this approach is that you can refine search results incrementally.
That is not possible with a normal query since the in
clause needs separate values and not a single value containing a comma separated list. One solution would be a dynamic query
declare @myList varchar(100)
set @myList = '(1,2,5,7,10)'
exec('select * from DBTable where id IN ' + @myList)
EDIT
Here are two versions. One using ArrayList
and other using HashSet
Compare them and create your own version from this, until you get what you need.
This should be enough to cover the:
P.S: It is not a school assignment :) So if you just guide me it will be enough
part of your question.
continuing with the original answer:
You may use a java.util.Collection
and/or java.util.ArrayList
for that.
The retainAll method does the following:
Retains only the elements in this collection that are contained in the specified collection
see this sample:
import java.util.Collection;
import java.util.ArrayList;
import java.util.Arrays;
public class Repeated {
public static void main( String [] args ) {
Collection listOne = new ArrayList(Arrays.asList("milan","dingo", "elpha", "hafil", "meat", "iga", "neeta.peeta"));
Collection listTwo = new ArrayList(Arrays.asList("hafil", "iga", "binga", "mike", "dingo"));
listOne.retainAll( listTwo );
System.out.println( listOne );
}
}
EDIT
For the second part ( similar values ) you may use the removeAll method:
Removes all of this collection's elements that are also contained in the specified collection.
This second version gives you also the similar values and handles repeated ( by discarding them).
This time the Collection
could be a Set
instead of a List
( the difference is, the Set doesn't allow repeated values )
import java.util.Collection;
import java.util.HashSet;
import java.util.Arrays;
class Repeated {
public static void main( String [] args ) {
Collection<String> listOne = Arrays.asList("milan","iga",
"dingo","iga",
"elpha","iga",
"hafil","iga",
"meat","iga",
"neeta.peeta","iga");
Collection<String> listTwo = Arrays.asList("hafil",
"iga",
"binga",
"mike",
"dingo","dingo","dingo");
Collection<String> similar = new HashSet<String>( listOne );
Collection<String> different = new HashSet<String>();
different.addAll( listOne );
different.addAll( listTwo );
similar.retainAll( listTwo );
different.removeAll( similar );
System.out.printf("One:%s%nTwo:%s%nSimilar:%s%nDifferent:%s%n", listOne, listTwo, similar, different);
}
}
Output:
$ java Repeated
One:[milan, iga, dingo, iga, elpha, iga, hafil, iga, meat, iga, neeta.peeta, iga]
Two:[hafil, iga, binga, mike, dingo, dingo, dingo]
Similar:[dingo, iga, hafil]
Different:[mike, binga, milan, meat, elpha, neeta.peeta]
If it doesn't do exactly what you need, it gives you a good start so you can handle from here.
Question for the reader: How would you include all the repeated values?
It is not very nice to use native php resources like $_GET
as Laravel gives us easy ways to get the variables. As a matter of standard, whenever possible use the resources of the laravel itself instead of pure PHP.
There is at least two modes to get variables by GET in Laravel ( Laravel 5.x or greater):
Mode 1
Route:
Route::get('computers={id}', 'ComputersController@index');
Request (POSTMAN or client...):
http://localhost/api/computers=500
Controler - You can access the {id}
paramter in the Controlller by:
public function index(Request $request, $id){
return $id;
}
Mode 2
Route:
Route::get('computers', 'ComputersController@index');
Request (POSTMAN or client...):
http://localhost/api/computers?id=500
Controler - You can access the ?id
paramter in the Controlller by:
public function index(Request $request){
return $request->input('id');
}
Old question but anyway !
Same thing happen to me this morning, everything was working fine for weeks before...... yes guess what ... I change my windows PC user account password yesterday night !!!!! (how stupid was I !!!)
So easy fix : IIS -> authentication -> Anonymous authentication -> edit and set the user and new PASSWORD !!!!!
Check if you have installed psycopg2 if not
sudo apt-get install psycopg2
Install the dependencies.
sudo apt-get build-dep python-psycopg2
These two commands should solve the problem.
I solved my problem simply using ng-init
for default selection instead of ng-checked
<div ng-init="person.billing=FALSE"></div>
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="FALSE" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="TRUE" />
For this problem Onpagechange listener is the best one But it will also have one small mistake that is it will not detect the starting time time of 0th position Once you will change the page it will starts to detect the Page selected position...For this problem I fount the easiest solution
1.You have to maintain the selected position value then use it....
2. Case 1: At the starting of the position is always Zero....
Case 2: Suppose if you set the current item means you will set that value into maintain position
3.Then do your action with the use of that maintain in your activity...

hg status will show you all the new files, and then you can just rm them.
Normally I want to get rid of ignored and unversioned files, so:
hg status -iu # to show
hg status -iun0 | xargs -r0 rm # to destroy
And then follow that with:
hg update -C -r xxxxx
which puts all the versioned files in the right state for revision xxxx
To follow the Stack Overflow tradition of telling you that you don't want to do this, I often find that this "Nuclear Option" has destroyed stuff I care about.
The right way to do it is to have a 'make clean' option in your build process, and maybe a 'make reallyclean' and 'make distclean' too.

You can use:
$(window).unload(function() {
//do something
}
Unload() is deprecated in jQuery version 1.8, so if you use jQuery > 1.8 you can use even beforeunload instead.
The beforeunload event fires whenever the user leaves your page for any reason.
$(window).on("beforeunload", function() {
return confirm("Do you really want to close?");
})

Actually you are right: it runs another instance of make. A possible solution would be:
.PHONY : clearscr fresh clean all
all :
compile executable
clean :
rm -f *.o $(EXEC)
fresh : clean clearscr all
clearscr:
clear
By calling make fresh
you get first the clean
target, then the clearscreen
which runs clear
and finally all
which does the job.
EDIT Aug 4
What happens in the case of parallel builds with make’s -j
option?
There's a way of fixing the order. From the make manual, section 4.2:
Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites
The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).
Hence the makefile becomes
.PHONY : clearscr fresh clean all
all :
compile executable
clean :
rm -f *.o $(EXEC)
fresh : | clean clearscr all
clearscr:
clear
EDIT Dec 5
It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.
log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)
install:
@[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
command1 # this line will be a subshell
command2 # this line will be another subshell
@command3 # Use `@` to hide the command line
$(call log_error, "It works, yey!")
uninstall:
@[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
....
$(call log_error, "Nuked!")
// acos(0.0) will return value of pi/2, inverse of cos(0) is pi/2
double pi = 2 * acos(0.0);
int n; // upto 6 digit
scanf("%d",&n); //precision with which you want the value of pi
printf("%.*lf\n",n,pi); // * will get replaced by n which is the required precision
As well as having then
on a new line, you also need a space before and after the [
, which is a special symbol in BASH.
#!/bin/bash
echo "start\n"
for f in *.jpg
do
fname=$(basename "$f")
echo "fname is $fname\n"

echo "fname is $fname\n"
if [ $((fname % 2)) -eq 1 ]
then
echo "removing $fname\n"
rm "$f"

I do not know why you are defining the parameter outside the script. That is unnecessary. Your callback function will be called with the return data as a parameter automatically. It is very possible to define your callback outside the sucess:
i.e.
function getData() {
$.ajax({
url : 'example.com',
type: 'GET',
success : handleData
})
}
function handleData(data) {
alert(data);
//do some stuff
}
the handleData function will be called and the parameter passed to it by the ajax function.

Swift has a powerful type inference. Lets get rid of "if let" or "guard let" boilerplate and force unwraps using functional approach:
let json: Dictionary<String, Any>? = ["current": ["temperature": 10]]
/// Curry
public func curry<A, B, C>(_ f: @escaping (A, B) -> C) -> (A) -> (B) -> C {
return { a in
{ f(a, $0) }
}
}
/// Function that takes key and optional dictionary and returns optional value
public func extract<Key, Value>(_ key: Key, _ json: Dictionary<Key, Any>?) -> Value? {
return json.flatMap {
cast($0[key])
}
}
/// Function that takes key and return function that takes optional dictionary and returns optional value
public func extract<Key, Value>(_ key: Key) -> (Dictionary<Key, Any>?) -> Value? {
return curry(extract)(key)
}
/// Precedence group for our operator
precedencegroup RightApplyPrecedence {
associativity: right
higherThan: AssignmentPrecedence
lowerThan: TernaryPrecedence
}
/// Apply. g § f § a === g(f(a))
infix operator § : RightApplyPrecedence
public func §<A, B>(_ f: (A) -> B, _ a: A) -> B {
return f(a)
}
/// Wrapper around operator "as".
public func cast<A, B>(_ a: A) -> B? {
return a as? B
}
let temperature = (extract("temperature") § extract("current") § json) ?? NSNotFound
Just one line of code and no force unwraps or manual type casting. This code works in playground, so you can copy and check it. Here is an implementation on GitHub.
Change the code like this. It works perfectly:
public function uploadImageFile() //gallery insert
{
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$new_image_name = time() . str_replace(str_split(' ()\\/,:*?"<>|'), '',
$_FILES['image_file']['name']);
$config['upload_path'] = 'uploads/gallery/';
$config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
$config['file_name'] = $new_image_name;
$config['max_size'] = '0';
$config['max_width'] = '0';
$config['max_height'] = '0';
$config['$min_width'] = '0';
$config['min_height'] = '0';
$this->load->library('upload', $config);
$upload = $this->upload->do_upload('image_file');
$title=$this->input->post('title');
$value=array('title'=>$title,'image_name'=>
$new_image_name,'crop_name'=>$crop_image_name);}
Try this:
s = 'hello plombier pantin'
print (s.find('p'))
6
print (s.index('p'))
6
print (s.rindex('p'))
15
print (s.rfind('p'))
Sometimes it happens if you either:
If it 'suddenly' happens after such, and your code has build-time errors then try fixing those errors first.
What happens is that as your solution is built, DLL files are created and stored in the projects bin folder. If there is an error in your code during build-time, the DLL files aren't created properly which brings up an error.
A 'quick fix' would be to fix all your errors or comment them out (if they wont affect other web pages.) then rebuild project/solution
If this doesn't work then try changing: CodeBehind="blahblahblah.aspx.cs"
to: CodeFile="blahblahblah.aspx.cs"
Note: Change "blahblahblah" to the pages real name.
The solution for me on a CentOS 8 system was checking the System Cryptography Policy by verifying the /etc/crypto-policies/config reads the default value of DEFAULT rather than any other value.
Once changing this value to DEFAULT, run the following command:
/usr/bin/update-crypto-policies --set DEFAULT
Rerun the curl command and it should work.
You can "compute the value for the specified byte array" using ComputeHash
:
var hash = sha1.ComputeHash(temp);
If you want to analyse the result in string representation, then you will need to format the bytes using the {0:X2}
format specifier.
There are two ways to correct the input data described here, or, more specifically and in line with the OP, to make Python module base64's b64decode method able to process the input data to something without raising an un-caught exception:
If that raises an exception, then
i. Catch it via try/except,
ii. (R?)Strip any = characters from the input data (N.B. this may not be necessary),
iii. Append A== to the input data (A== through P== will work),
iv. Call base64.b64decode(...) with those A==-appended input data
The result from Item 1. or Item 2. above will yield the desired result.
Caveats
This does not guarantee the decoded result will be what was originally encoded, but it will (sometimes?) give the OP enough to work with:
Even with corruption I want to get back to the binary because I can still get some useful info from the ASN.1 stream").
See What we know and Assumptions below.
TL;DR
From some quick tests of base64.b64decode(...)
it appears that it ignores non-[A-Za-z0-9+/] characters; that includes ignoring =s unless they are the last character(s) in a parsed group of four, in which case the =s terminate the decoding (a=b=c=d= gives the same result as abc=, and a==b==c== gives the same result as ab==).
It also appears that all characters appended are ignored after the point where base64.b64decode(...) terminates decoding e.g. from an = as the fourth in a group.
As noted in several comments above, there are either zero, or one, or two, =s of padding required at the end of input data for when the [number of parsed characters to that point modulo 4] value is 0, or 3, or 2, respectively. So, from items 3. and 4. above, appending two or more =s to the input data will correct any [Incorrect padding] problems in those cases.
HOWEVER, decoding cannot handle the case where the [total number of parsed characters modulo 4] is 1, because it takes a least two encoded characters to represent the first decoded byte in a group of three decoded bytes. In uncorrupted encoded input data, this [N modulo 4]=1 case never happens, but as the OP stated that characters may be missing, it could happen here. That is why simply appending =s will not always work, and why appending A== will work when appending == does not. N.B. Using [A] is all but arbitrary: it adds only cleared (zero) bits to the decoded, which may or not be correct, but then the object here is not correctness but completion by base64.b64decode(...) sans exceptions.
What we know from the OP and especially subsequent comments is

Here is a wrapper to implement this solution:
In your binding configuration, there are four timeout values you can tweak:
<bindings>
<basicHttpBinding>
<binding name="IncreasedTimeout"
sendTimeout="00:25:00">
</binding>
</basicHttpBinding>
The most important is the sendTimeout
, which says how long the client will wait for a response from your WCF service. You can specify hours:minutes:seconds
in your settings - in my sample, I set the timeout to 25 minutes.
The openTimeout
as the name implies is the amount of time you're willing to wait when you open the connection to your WCF service. Similarly, the closeTimeout
is the amount of time when you close the connection (dispose the client proxy) that you'll wait before an exception is thrown.
The receiveTimeout
is a bit like a mirror for the sendTimeout
- while the send timeout is the amount of time you'll wait for a response from the server, the receiveTimeout
is the amount of time you'll give you client to receive and process the response from the server.
In case you're send back and forth "normal" messages, both can be pretty short - especially the receiveTimeout
, since receiving a SOAP message, decrypting, checking and deserializing it should take almost no time. The story is different with streaming - in that case, you might need more time on the client to actually complete the "download" of the stream you get back from the server.
There's also openTimeout, receiveTimeout, and closeTimeout. The MSDN docs on binding gives you more information on what these are for.
To get a serious grip on all the intricasies of WCF, I would strongly recommend you purchase the "Learning WCF" book by Michele Leroux Bustamante:
and you also spend some time watching her 15-part "WCF Top to Bottom" screencast series - highly recommended!
For more advanced topics I recommend that you check out Juwal Lowy's Programming WCF Services book.

Just the thread.
Also, if you want case-insensitive comparison, in recent versions of Java the String
class contains a public static final
field called CASE_INSENSITIVE_ORDER
which is of type Comparator<String>
, as I just recently found out. So, you can get your job done using String.CASE_INSENSITIVE_ORDER
.

(Added a timer for safari 5.0)
// managage back button click (and backspace)
var count = 0; // needed for safari
window.onload = function () {
if (typeof history.pushState === "function") {
history.pushState("back", null, null);
window.onpopstate = function () {
history.pushState('back', null, null);
if(count == 1){window.location = 'your url';}
};
}
}
setTimeout(function(){count = 1;},200);
I haven't used jQuery, but in a library like Prototype you can bind functions to a specific scope. So with that in mind your code would look like this:
$('#foobar').ready('click', this.doSomething.bind(this));
The bind method returns a new function that calls the original method with the scope you have specified.
Bootstrap 3
Here is a working left sidebar example:
http://bootply.com/90936 (similar to the Bootstrap docs)
The trick is using the affix
component along with some CSS to position it:
#sidebar.affix-top {
position: static;
margin-top:30px;
width:228px;
}
#sidebar.affix {
position: fixed;
top:70px;
width:228px;
}
EDIT- Another example with footer and affix-bottom
Bootstrap 4
The Affix component has been removed in Bootstrap 4, so to create a sticky sidebar, you can use a 3rd party Affix plugin like this Bootstrap 4 sticky sidebar example, or use the sticky-top
class is explained in this answer.

Open an elevated Command Prompt (run cmd as administrator). query your registry for available TT fonts to the console by:
REG query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont"
You'll see an output like :
0 REG_SZ Lucida Console
00 REG_SZ Consolas
936 REG_SZ *???
932 REG_SZ *MS ????
Now we need to add a TT font that supports the characters you need like Courier New, we do this by adding zeros to the string name, so in this case the next one would be "000" :
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont" /v 000 /t REG_SZ /d "Courier New"
Now we implement UTF-8 support:
REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f
Set default font to "Courier New":
REG ADD HKCU\Console /v FaceName /t REG_SZ /d "Courier New" /f
Set font size to 20 :
REG ADD HKCU\Console /v FontSize /t REG_DWORD /d 20 /f
Enable quick edit if you like :
REG ADD HKCU\Console /v QuickEdit /t REG_DWORD /d 1 /f
Very common problem in android
It can be broken down into 3 Pieces
1 ) start Activity B (Happens in Activity A)
2 ) Set requested data (Happens in activity B)
3 ) Receive requested data (Happens in activity A)
1) startActivity B
Intent i = new Intent(A.this, B.class);
startActivity(i);
2) Set requested data
In this part, you decide whether you want to send data back or not when a particular event occurs.
Eg: In activity B there is an EditText and two buttons b1, b2.
Clicking on Button b1 sends data back to activity A
Clicking on Button b2 does not send any data.
Sending data
b1......clickListener
{
Intent resultIntent = new Intent();
resultIntent.putExtra("Your_key","Your_value");
setResult(RES_CODE_A,resultIntent);
finish();
}
Not sending data
b2......clickListener
{
setResult(RES_CODE_B,new Intent());
finish();
}
user clicks back button
By default, the result is set with Activity.RESULT_CANCEL response code
3) Retrieve result
For that override onActivityResult method
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RES_CODE_A) {
// b1 was clicked
String x = data.getStringExtra("RES_CODE_A");
}
else if(resultCode == RES_CODE_B){
// b2 was clicked
}
else{
// back button clicked
}
}
Main Example
The example below will run myfile.sql on database mydatabase using schema myschema.
psql "dbname=mydatabase options=--search_path=myschema" -a -f myfile.sql
The way this works is the first argument to the psql command is the dbname argument. The docs mention a connection string can be provided.
If this parameter contains an = sign or starts with a valid URI prefix (postgresql:// or postgres://), it is treated as a conninfo string
The dbname keyword specifies the database to connect to and the options keyword lets you specify command-line options to send to the server at connection startup. Those options are detailed in the server configuration chapter. The option we are using to select the schema is search_path.
Another Example
The example below will connect to host myhost on database mydatabase using schema myschema. The =
special character must be url escaped with the escape sequence %3D
.
psql postgres://myuser@myhost?options=--search_path%3Dmyschema
The following example centers a frame on the screen:
package com.zetcode;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GraphicsEnvironment;
import java.awt.Point;
import javax.swing.JFrame;
public class CenterOnScreen extends JFrame {
public CenterOnScreen() {
initUI();
}
private void initUI() {
setSize(250, 200);
centerFrame();
setTitle("Center");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private void centerFrame() {
Dimension windowSize = getSize();
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
Point centerPoint = ge.getCenterPoint();
int dx = centerPoint.x - windowSize.width / 2;
int dy = centerPoint.y - windowSize.height / 2;
setLocation(dx, dy);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
CenterOnScreen ex = new CenterOnScreen();
ex.setVisible(true);
}
});
}
}
In order to center a frame on a screen, we need to get the local
graphics environment. From this environment, we determine the
center point. In conjunction with the frame size, we manage
to center the frame. The setLocation()
is the method that
moves the frame to the central position.
Note that this is actually what the setLocationRelativeTo(null)
does:
public void setLocationRelativeTo(Component c) {
// target location
int dx = 0, dy = 0;
// target GC
GraphicsConfiguration gc = getGraphicsConfiguration_NoClientCode();
Rectangle gcBounds = gc.getBounds();
Dimension windowSize = getSize();
// search a top-level of c
Window componentWindow = SunToolkit.getContainingWindow(c);
if ((c == null) || (componentWindow == null)) {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
gc = ge.getDefaultScreenDevice().getDefaultConfiguration();
gcBounds = gc.getBounds();
Point centerPoint = ge.getCenterPoint();
dx = centerPoint.x - windowSize.width / 2;
dy = centerPoint.y - windowSize.height / 2;
}
...
setLocation(dx, dy);
}
You will need to get the textbox via javascript when moving the mouse over it and change its type
to text
. And when moving it out, you will want to change it back to password
. No chance of doing this in pure CSS.
HTML:
<input type="password" name="password" id="myPassword" size="30" />
<img src="theicon" onmouseover="mouseoverPass();" onmouseout="mouseoutPass();" />
JS:
function mouseoverPass(obj) {
var obj = document.getElementById('myPassword');
obj.type = "text";
}
function mouseoutPass(obj) {
var obj = document.getElementById('myPassword');
obj.type = "password";
}
for first key of object you can use
console.log(Object.keys(object)[0]);//print key's name
for value
console.log(object[Object.keys(object)[0]]);//print key's value
for entry in "$search_dir"/*
do
echo "$entry"
done
You are experiencing this issue for two reasons.
When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)
User.java
@Entity
@Table(name="user")
public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="iduser")
private Long idUser;
@Column(name="user_name")
private String userName;
@OneToOne()
@JoinColumn(name="idarea")
private Area area;
public Long getIdUser() {
return idUser;
}
public void setIdUser(Long idUser) {
this.idUser = idUser;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Area getArea() {
return area;
}
public void setArea(Area area) {
this.area = area;
}
}
Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:
@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")
While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.
Area.java
@Entity
@Table(name = "area")
public class Area {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="idarea")
private Long idArea;
@Column(name="area_name")
private String areaName;
@OneToOne(fetch=FetchType.LAZY, mappedBy="area")
private User user;
public Long getIdArea() {
return idArea;
}
public void setIdArea(Long idArea) {
this.idArea = idArea;
}
public String getAreaName() {
return areaName;
}
public void setAreaName(String areaName) {
this.areaName = areaName;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
This is sort of possible with FireFox now thanks to the element style attribute.
This experimental attribute lets you use any HTML content as a background image. So, to create the background you need three overlays:
-moz-element
background that sets the content. Note that FX doesn't support the filter: blur()
attribute, so we need to us an SVG.So, put together:
SVG blur filter (works in FX, other browsers could use filter:blur()
):
<svg>
<defs>
<filter id="svgBlur">
<feGaussianBlur stdDeviation="10"/>
</filter>
</defs>
</svg>
CSS blur style:
.behind-blur
{
filter : url(#svgBlur);
opacity: .4;
background: -moz-element(#content);
background-repeat: no-repeat;
}
Finally 3 layers:
<div class="header" style="background-color: #fff"> </div>
<div class="header behind-blur"> </div>
<div class="header">
Header Text, content blurs behind
</div>
Then to move this around just set the background-position
(sample in jQuery but you could use anything):
$('.behind-blur').css({
'background-position': '-' + left + 'px -' + top + 'px'
});

There's a lot of typedef
going on here. Personally I'm against "hiding the asterisk", i.e. typedef
:ing pointer types into something that doesn't look like a pointer. In C, pointers are quite important and really affect the code, there's a lot of difference between foo

Many of the answers are also confused about this, I think.
Your allocation of an array of Chess
values, which are pointers to values of type chess
(again, a very confusing nomenclature that I really can't recommend) should be like this:
Chess *array = malloc(n * sizeof *array);
Then, you need to initialize the actual instances, by looping:
for(i = 0; i < n; ++i)
array[i] = NULL;
This assumes you don't want to allocate any memory for the instances, you just want an array of pointers with all pointers initially pointing at nothing.
If you wanted to allocate space, the simplest form would be:
for(i = 0; i < n; ++i)
array[i] = malloc(sizeof *array[i]);
See how the sizeof
usage is 100% consistent, and never starts to mention explicit types. Use the type information inherent in your variables, and let the compiler worry about which type is which. Don't repeat yourself.
Of course, the above does a needlessly large amount of calls to malloc()
; depending on usage patterns it might be possible to do all of the above with just one call to malloc()
, after computing the total size needed. Then you'd still need to go through and initialize the array[i]
pointers to point into the large block, of course.
Add commons-collections4-x.x.jar file in your build path and try it again. It will work.

Here is how to delete ALL BUILDS FOR ALL JOBS...... using the Jenkins Scripting.

Use DateTime.AddDays()
(MSDN Documentation DateTime.AddDays Method).
DateTime tomorrow = DateTime.Now.AddDays(1);
DateTime yesterday = DateTime.Now.AddDays(-1);
Just to add to @ThijsW's answer, there is a significant speed advantage to the first method over the concatenation method:
big = 1e5;
tic;
x = rand(big,1);
toc
x = zeros(big,1);
tic;
for ii = 1:big
x(ii) = rand;
end
toc
x = [];
tic;
for ii = 1:big
x(end+1) = rand;
end;
toc
x = [];
tic;
for ii = 1:big
x = [x rand];
end;
toc
Elapsed time is 0.004611 seconds.
Elapsed time is 0.016448 seconds.
Elapsed time is 0.034107 seconds.
Elapsed time is 12.341434 seconds.
I got these times running in 2012b however when I ran the same code on the same computer in matlab 2010a I get
Elapsed time is 0.003044 seconds.
Elapsed time is 0.009947 seconds.
Elapsed time is 12.013875 seconds.

So I guess the speed advantage only applies to more recent versions of Matlab
int max = list.Any() ? list.Max(i => i.MyCounter) : 0;
If the list has any elements (ie. not empty), it will take the max of the MyCounter field, else will return 0.
To stop the service we must use the method stopService()
:
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
//startService(myService);
stopService(myService);
then the method onDestroy()
in the service is called:
@Override
public void onDestroy() {
Log.i(TAG, "onCreate() , service stopped...");
}
Here is a complete example including how to stop the service.
The easiest way that I can see is delete node_modules

Have you tried:
db.posts.find({"created_on": {"$gte": new Date(2012, 7, 14), "$lt": new Date(2012, 7, 15)}})
The problem you're going to run into is that dates are stored as timestamps in Mongo. So, to match a date you're asking it to match a timestamp. In your case I think you're trying to match a day (ie. from 00:00 to 23:59 on a specific date). If your dates are stored without times then you should be okay. Otherwise, try specifying your date as a range of time on the same day (ie. start=00:00, end=23:59) if gte doesn't work.
Here's the filter that I ended up using for strftime in Jinja2 and Flask
@app.template_filter('strftime')
def _jinja2_filter_datetime(date, fmt=None):
date = dateutil.parser.parse(date)
native = date.replace(tzinfo=None)
format='%b %d, %Y'
return native.strftime(format)
And then you use the filter like so:
{{car.date_of_manufacture|strftime}}
Following steps solved the issue for me..
Copied the zip file into the Program Files folder and extracted to "apache-maven-3.6.3-bin".
Then copied the path, C:\Program Files\apache-maven-3.6.3-bin\apache-maven-3.6.3
Then created the new MAVEN_HOME variable within environmental variables with the above path.
Also added,
C:\Program Files\apache-maven-3.6.3-bin\apache-maven-3.6.3\bin

Just change +
to -
:
str = str.replace(/[^a-z0-9-]/g, "");
You can read it as:
[^ ]
: match NOT from the set[^a-z0-9-]
: match if not a-z
, 0-9
or -
/ /g
: do global matchMore information:
you can use Like statement if you are searching for any particular column
ex:

Additionally you could set the service to automatic so that it will work after a reboot
When you use a code like this:
using (var rsa = new RSACryptoServiceProvider(1024))
{
// Do something with the key...
// Encrypt, export, etc.
}
.NET (actually Windows) stores your key in a persistent key container forever. The container is randomly generated by .NET
This means:
Any random RSA/DSA key you have EVER generated for the purpose of protecting data, creating custom X.509 certificate, etc. may have been exposed without your awareness in the Windows file system. Accessible by anyone who has access to your account.
Your disk is being slowly filled with data. Normally not a big concern but it depends on your application (e.g. it might generates hundreds of keys every minute).
To resolve these issues:
using (var rsa = new RSACryptoServiceProvider(1024))
{
try
{
// Do something with the key...
// Encrypt, export, etc.
}
finally
{
rsa.PersistKeyInCsp = false;
}
}

Keyboard shortcuts such as Ctrl+Shift+R work on Android too, you just need a keyboard capable of sending these keys. I used Hacker's Keyboard to send Ctrl+Shift+R, which did a hard reload on my phone.

Let me add an example here:
I'm trying to build Alluxio
on windows platform and got the same issue, it's because the pom.xml
contains below step:

<inherited>false</inherited>
<executions>
<execution>

</goals>
<configuration>
<executable>${build.path}/style/check_no_windows_line_endings.sh</executable>

The .sh
file is not executable on windows so the error throws.
Comment it out if you do want build Alluxio

Consider:
class Bike(object):
def __init__(self, name, weight, cost):
self.name = name
self.weight = weight
self.cost = cost
bikes = {
# Bike designed for children"
"Trike": Bike("Trike", 20, 100), # <--
# Bike designed for everyone"
"Kruzer": Bike("Kruzer", 50, 165), # <--
}
# Markup of 20% on all sales
margin = .2
# Revenue minus cost after sale
for bike in bikes.values():
profit = bike.cost * margin
print(profit)
Output:
33.0 20.0
The difference is that in your bikes
dictionary, you're initializing the values as lists [...]
. Instead, it looks like the rest of your code wants Bike
instances. So create Bike
instances: Bike(...)
.
As for your error
AttributeError: 'list' object has no attribute 'cost'
this will occur when you try to call .cost
on a list
object. Pretty straightforward, but we can figure out what happened by looking at where you call .cost
-- in this line:
profit = bike.cost * margin
This indicates that at least one bike
(that is, a member of bikes.values()
is a list). If you look at where you defined bikes
you can see that the values were, in fact, lists. So this error makes sense.
But since your class has a cost attribute, it looked like you were trying to use Bike
instances as values, so I made that little change:
[...] -> Bike(...)
and you're all set.
This is my generic solution for any string s
and any index i
:
def remove_at(i, s):
return s[:i] + s[i+1:]
You can use a SqlDataAdapter
:
SqlDataAdapter adapter = new SqlDataAdapter();
SqlCommand cmd = new SqlCommand("usp_GetABCD", sqlcon);
cmd.CommandType = CommandType.StoredProcedure;
adapter.SelectCommand = cmd;
DataTable dt = new DataTable();
adapter.Fill(dt);
In my case it worked great just by doing the following:
[HttpPost]
public ActionResult DoSomething(int custNum)
{
// Some magic code here...
}
<form id="frmSomething" method="post">
<div>
<!-- Some magic html here... -->
</div>
<button id="btnSubmit" type="submit">Submit</button>
</form>
var frmSomething= $("#frmSomething");
var btnSubmit= $("#btnSubmit");
var custNum = 100;
btnSubmit.click(function()
{
frmSomething.attr("action", "/Home/DoSomething?custNum=" + custNum);
btnSubmit.submit();
});
Hope this helps vatos!
Rails has a built in way to seed data as explained here.
Another way would be to use a gem for more advanced or easy seeding such as: seedbank.
The main advantage of this gem and the reason I use it is that it has advanced capabilities such as data loading dependencies and per environment seed data.
Adding an up to date answer as this answer was first on google.
From Eclipsepedia on how to set a conditional breakpoint:
First, set a breakpoint at a given location. Then, use the context menu on the breakpoint in the left editor margin or in the Breakpoints view in the Debug perspective, and select the breakpoint’s properties. In the dialog box, check Enable Condition, and enter an arbitrary Java condition, such as
list.size()==0
. Now, each time the breakpoint is reached, the expression is evaluated in the context of the breakpoint execution, and the breakpoint is either ignored or honored, depending on the outcome of the expression.Conditions can also be expressed in terms of other breakpoint attributes, such as hit count.
Since it's from Oracle, how about a lookup table of pre calculated answers. :-D
You could use
os.path.abspath(path_with_backlash)
it returns the path with \
Make sure to watch your selectors. You appear to have forgotten the #
for div2
. Additionally, you can toggle the visibility of many elements at once with .toggle()
:
// Short-form of `document.ready`
$(function(){
$("#div2").hide();
$("#preview").on("click", function(){
$("#div1, #div2").toggle();
});
});
You can use array to handle several button click listener in android like this: here i am setting button click listener for n buttons by using array as:
Button btn[] = new Button[n];
NOTE: n is a constant positive integer
Code example:
//class androidMultipleButtonActions
package a.b.c.app;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class androidMultipleButtonActions extends Activity implements OnClickListener{
Button btn[] = new Button[3];
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn[0] = (Button) findViewById(R.id.Button1);
btn[1] = (Button) findViewById(R.id.Button2);
btn[2] = (Button) findViewById(R.id.Button3);
for(int i=0; i<3; i++){
btn[i].setOnClickListener(this);
}
}
public void onClick(View v) {
if(v == findViewById(R.id.Button1)){
//do here what u wanna do.
}
else if(v == findViewById(R.id.Button2)){
//do here what u wanna do.
}
else if(v == findViewById(R.id.Button3)){
//do here what u wanna do.
}
}
}
Note: First write an main.xml file if u dont know how to write please mail to: [email protected]
when spring boot project running as a jar and need read some file in classpath, I implement it by below code
Resource resource = new ClassPathResource("data.sql");
BufferedReader reader = new BufferedReader(new InputStreamReader(resource.getInputStream()));
reader.lines().forEach(System.out::println);
Try with:
^(\w+ ?)*$
Explanation:
\w - alias for [a-zA-Z_0-9]
"whitespace"? - allow whitespace after word, set is as optional
I would say that the basic difference is this:
Grids are used as computing/storage platform.
We start talking about cloud computing when it offers services. I would almost say that cloud computing is higher-level grid. Now I know these are not definitions, but maybe it will make it more clear.
As far as application domains go, grids require users (developers mostly) to actually create services from low-level functions that grid offers. Cloud will offer complete blocks of functionality that you can use in your application.
Example (you want to create physical simulation of ball dropping from certain height): Grid: Study how to compute physics on a computer, create appropriate code, optimize it for certain hardware, think about paralellization, set inputs send application to grid and wait for answer
Cloud: Set diameter of a ball, material from pre-set types, height from which the ball is dropping, etc and ask for results
I would say that if you created OS for grid, you would actually create cloud OS.
These paradigms don't have to be mutually exclusive. If you look at python, it supports functions and classes, but at the same time, everything is an object, including functions. You can mix and match functional/oop/procedural style all in one piece of code.
What I mean is, in functional languages (at least in Haskell, the only one I studied) there are no statements! functions are only allowed one expression inside them!! BUT, functions are first-class citizens, you can pass them around as parameters, along with a bunch of other abilities. They can do powerful things with few lines of code.
While in a procedural language like C, the only way you can pass functions around is by using function pointers, and that alone doesn't enable many powerful tasks.
In python, a function is a first-class citizen, but it can contain arbitrary number of statements. So you can have a function that contains procedural code, but you can pass it around just like functional languages.
Same goes for OOP. A language like Java doesn't allow you to write procedures/functions outside of a class. The only way to pass a function around is to wrap it in an object that implements that function, and then pass that object around.
In Python, you don't have this restriction.
It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down. If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.
and awk as well
awk 'NR!~/^(5|10|25)$/' file
This is the best method:
public static boolean isValidEmail(String enteredEmail){
String EMAIL_REGIX = "^[\\\\w!#$%&’*+/=?`{|}~^-]+(?:\\\\.[\\\\w!#$%&’*+/=?`{|}~^-]+)*@(?:[a-zA-Z0-9-]+\\\\.)+[a-zA-Z]{2,6}$";
Pattern pattern = Pattern.compile(EMAIL_REGIX);
Matcher matcher = pattern.matcher(enteredEmail);
return ((!enteredEmail.isEmpty()) && (enteredEmail!=null) && (matcher.matches()));
}

+1 means 2 days ago. It's rounded.
You need to assign display: block;
property to the wrapping anchor. Otherwise it won't wrap correctly.
<a style="display:block" href="http://justinbieber.com">
<div class="xyz">My div contents</div>
</a>
You can also use the good old micro clearfix for this.
#container::before, #container::after{
content: ' ';
display: table;
}

Use this syntax for VB.NET 2005/2008 compatibility:
Dim theVar As New List(Of String)(New String() {"one", "two", "three"})
Although the VB.NET 2010 syntax is prettier.
While you can use rand(42-10) + 10
to get a random number between 10
and 42
(where 10 is inclusive and 42 exclusive), there's a better way since Ruby 1.9.3, where you are able to call:
rand(10...42) # => 13
Available for all versions of Ruby by requiring my backports
gem.
Ruby 1.9.2 also introduced the Random
class so you can create your own random number generator objects and has a nice API:
r = Random.new
r.rand(10...42) # => 22
r.bytes(3) # => "rnd"
The Random
class itself acts as a random generator, so you call directly:
Random.rand(10...42) # => same as rand(10...42)
Notes on Random.new
In most cases, the simplest is to use rand
or Random.rand
. Creating a new random generator each time you want a random number is a really bad idea. If you do this, you will get the random properties of the initial seeding algorithm which are atrocious compared to the properties of the random generator itself.
If you use Random.new
, you should thus call it as rarely as possible, for example once as MyApp::Random = Random.new
and use it everywhere else.
The cases where Random.new
is helpful are the following:
rand
/Random.rand

objects can marshalled)Go strings are not null terminated, and to remove the last char of a string you can simply do:
s = s[:len(s)-1]
Suppose your function enters data in columns A and B and you want to a custom Userform to appear if the user selects a cell in column C. One way to do this is to use the SelectionChange
event:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim clickRng As Range
Dim lastRow As Long
lastRow = Range("A1").End(xlDown).Row
Set clickRng = Range("C1:C" & lastRow) //Dynamically set cells that can be clicked based on data in column A
If Not Intersect(Target, clickRng) Is Nothing Then
MyUserForm.Show //Launch custom userform
End If
End Sub
Note that the userform will appear when a user selects any cell in Column C and you might want to populate each cell in Column C with something like "select cell to launch form" to make it obvious that the user needs to perform an action (having a button naturally suggests that it should be clicked)
Because you can break out of a do/while loop, let us "do" one round. With a while(false) at the end, the condition is never true and will not repeat, again.
do
{
$subjectText = trim(filter_input(INPUT_POST, 'subject'));
if(!$subjectText)
{
$smallInfo = 'Please give a subject.';
break;
}
$messageText = trim(filter_input(INPUT_POST, 'message'));
if(!$messageText)
{
$smallInfo = 'Please supply a message.';
break;
}
} while(false);
I had a similar task to do, but it contained some aspects that were not sufficiently covered by the other answers here:
I did not try fast-export and hg-fast-export, since they require that you have Python and some Mercurial Python modules on your machine, which I didn't have.
I did try hg-init with TortoiseHG, and this answer gave me a good start. But it looked like it only converts the current branch, not all at once (*). So I read the hg-init docs and this blog post and added
[git]
branch_bookmark_suffix=_bookmark
to my mercurial.ini, and did
hg bookmarks -r default master
hg bookmarks -r my_branch my_branch_bookmark
hg gexport
(Repeat the 2nd line for every branch you want to convert, and repeat it again if you should happen to do another commit before executing the 3rd line). This creates a folder git
within .hg
, which turns out to be a bare Git repo with all the exported branches. I could clone this repo and had a working copy as desired.
Or almost...
Running
git status
on my working copy showed all files with non-ASCII characters in their names as untracked files. So I continued researching and followed this advice:
git rm -rf --cached \*
git add --all
git commit
And finally the repo was ready to be pushed up to Bitbucket :-)
I also tried the Github importer as mentioned in this answer. I used Bitbucket as the source system, and Github did quite a good job, i.e. it converted all branches automatically. However, it showed '?'-characters for all non-ASCII characters in my commit messages (Web-UI and locally) and filenames (Web-UI only), and while I could fix the filenames as described above, I had no idea what to do with the commit messages, and so I'd prefer the hg-init approach. Without the encoding issue the Github importer would have been a perfect and fast solution (as long as you have a paid Github account or can tolerate that your repo is public for as long as it takes to pull it from Github to your local machine).
(*) So it looked like before I discovered that I have to bookmark all the branches I want to export. If you do and push to a bare (!) repo, like the linked answer says, you get all the branches.
The solution is
@RequestMapping(value = "processing", method = RequestMethod.GET)
public @ResponseBody ProcessResponse processData(@RequestParam("workflow") final String workflow,
@RequestParam("conf") final String value, @RequestParam("dc") final String dc, HttpServletRequest request) {
System.out.println(workflow);
System.out.println(value);
System.out.println(dc);
System.out.println(request.getRemoteAddr());
// some other code
}
Add HttpServletRequest request
to your method definition and then use the Servlet API
Spring Documentation here said in
15.3.2.3 Supported handler method arguments and return types
Handler methods that are annotated with @RequestMapping can have very flexible signatures.
Most of them can be used in arbitrary order (see below for more details).
Request or response objects (Servlet API). Choose any specific request or response type,
for example ServletRequest or HttpServletRequest
Considering the answer:
HttpWebRequest webRequest;
void StartWebRequest()
{
webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), null);
}
void FinishWebRequest(IAsyncResult result)
{
webRequest.EndGetResponse(result);
}
You could send the request pointer or any other object like this:
void StartWebRequest()
{
HttpWebRequest webRequest = ...;
webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), webRequest);
}
void FinishWebRequest(IAsyncResult result)
{
HttpWebResponse response = (result.AsyncState as HttpWebRequest).EndGetResponse(result) as HttpWebResponse;
}

Just in case someone comes here trying to know how to create a tuple assigning each part of the string "Quattro" and "TT" to an element of the list, it would be like this
print tuple(a.split())
Me, I'd do it something like this:
HTML:
onclick="myfunction({path:'/myController/myAction', ok:myfunctionOnOk, okArgs:['/myController2/myAction2','myParameter2'], cancel:myfunctionOnCancel, cancelArgs:['/myController3/myAction3','myParameter3']);"
JS:
function myfunction(params)
{
var path = params.path;
/* do stuff */
// on ok condition
params.ok(params.okArgs);
// on cancel condition
params.cancel(params.cancelArgs);
}
But then I'd also probable be binding a closure to a custom subscribed event. You need to add some detail to the question really, but being first-class functions are easily passable and getting params to them can be done any number of ways. I would avoid passing them as string labels though, the indirection is error prone.
You could use the CSS calc
parameter to calculate the height dynamically like so:
.dynamic-height {_x000D_

margin-top: calc(100% - 10px);_x000D_

}

If you want to select single entry for each user per day, then
SELECT * FROM table_name GROUP BY DAY(start_date),owner_name
As already stated: closures, out of the box, cannot be serialized.
However, using the __sleep()
, __wakeup()
magic methods and reflection u CAN manually make closures serializable. For more details see extending-php-5-3-closures-with-serialization-and-reflection
This makes use of reflection and the php function eval. Do note this opens up the possibility of CODE injection, so please take notice of WHAT you are serializing.
toFixed(n) provides n length after the decimal point; toPrecision(x) provides x total length.
Use this method below
// Example: toPrecision(4) when the number has 7 digits (3 before, 4 after)
// It will round to the tenths place
num = 500.2349;
result = num.toPrecision(4); // result will equal 500.2
AND if you want the number to be fixed use
result = num.toFixed(2);
All have explained in great detail and nothing I could add further. Though I would like to explain it in Layman's Terms or plain ENGLISH

1.99 is less precise than 1.999
1.999 is less precise than 1.9999
.....
A variable, able to store or represent "1.9" provides less precision than the one able to hold or represent 1.9999. These Fraction can amount to a huge difference in large calculations.
Consider using the MySQL Installer for Windows as it installs and updates the various MySQL products on your system, including MySQL Server, MySQL Workbench, and MySQL Notifier. The Notifier monitors your MySQL instances so you'll know if MySQL is running, and it can also be used to start/stop MySQL.
I need to click the link who's href has substring "long" in it. How can I do this?
With the beauty of CSS selectors.
your statement would be...
driver.findElement(By.cssSelector("a[href*='long']")).click();
This means, in english,
Find me any 'a' elements, that have the
href
attribute, and that attributecontains
'long'
You can find a useful article about formulating your own selectors for automation effectively, as well as a list of all the other equality operators. contains
, starts with
, etc... You can find that at: http://ddavison.io/css/2014/02/18/effective-css-selectors.html
You can use xdpyinfo
(can be installed via apt-get install x11-utils
).
Since there is no native way to do this ,Here is less intrusive solution i found (dont add any 'old' prototype methods):
var ListenerTracker=new function(){
var is_active=false;
// listener tracking datas
var _elements_ =[];
var _listeners_ =[];
this.init=function(){
if(!is_active){//avoid duplicate call
intercep_events_listeners();
}
is_active=true;
};
// register individual element an returns its corresponding listeners
var register_element=function(element){
if(_elements_.indexOf(element)==-1){
// NB : split by useCapture to make listener easier to find when removing
var elt_listeners=[{/*useCapture=false*/},{/*useCapture=true*/}];
_elements_.push(element);
_listeners_.push(elt_listeners);
}
return _listeners_[_elements_.indexOf(element)];
};
var intercep_events_listeners = function(){
// backup overrided methods
var _super_={
"addEventListener" : HTMLElement.prototype.addEventListener,
"removeEventListener" : HTMLElement.prototype.removeEventListener
};
Element.prototype["addEventListener"]=function(type, listener, useCapture){
var listeners=register_element(this);
// add event before to avoid registering if an error is thrown
_super_["addEventListener"].apply(this,arguments);
// adapt to 'elt_listeners' index
useCapture=useCapture?1:0;
if(!listeners[useCapture][type])listeners[useCapture][type]=[];
listeners[useCapture][type].push(listener);
};
Element.prototype["removeEventListener"]=function(type, listener, useCapture){
var listeners=register_element(this);
// add event before to avoid registering if an error is thrown
_super_["removeEventListener"].apply(this,arguments);
// adapt to 'elt_listeners' index
useCapture=useCapture?1:0;
if(!listeners[useCapture][type])return;
var lid = listeners[useCapture][type].indexOf(listener);
if(lid>-1)listeners[useCapture][type].splice(lid,1);
};
Element.prototype["getEventListeners"]=function(type){
var listeners=register_element(this);
// convert to listener datas list
var result=[];
for(var useCapture=0,list;list=listeners[useCapture];useCapture++){
if(typeof(type)=="string"){// filtered by type
if(list[type]){
for(var id in list[type]){
result.push({"type":type,"listener":list[type][id],"useCapture":!!useCapture});
}
}
}else{// all
for(var _type in list){
for(var id in list[_type]){
result.push({"type":_type,"listener":list[_type][id],"useCapture":!!useCapture});
}
}
}
}
return result;
};
};
}();
ListenerTracker.init();

As a companion to the answers explaining cleanup and install via homebrew, I found that homebrew itself provided clear indications of the symlink clashes.
Unfortunately it provides these one by one as it encounters them, so it is a little laborious, but it does seem to find all the clashes and was the only way I could get a clean install with homebrew.
Essentially, the process is:
Here is a screen output from the last steps of my install - you can see it results in a clean install (eventually...):

Add CSS to your inner div. Set margin: 0 auto
and set its width less than 100%, which is the width of the outer div.
<div id="outer" style="width:100%">
<div id="inner" style="margin:0 auto;width:50%">Foo foo</div>
</div>
This will give the desired result.
A few years ago it was said that update()
and digest()
were legacy methods and the new streaming API approach was introduced. Now the docs say that either method can be used. For example:
var crypto = require('crypto');
var text = 'I love cupcakes';
var secret = 'abcdeg'; //make this your secret!!
var algorithm = 'sha1'; //consider using sha256
var hash, hmac;
// Method 1 - Writing to a stream
hmac = crypto.createHmac(algorithm, secret);
hmac.write(text); // write in to the stream
hmac.end(); // can't read from the stream until you call end()
hash = hmac.read().toString('hex'); // read out hmac digest
console.log("Method 1: ", hash);
// Method 2 - Using update and digest:
hmac = crypto.createHmac(algorithm, secret);
hmac.update(text);
hash = hmac.digest('hex');
console.log("Method 2: ", hash);
Tested on node v6.2.2 and v7.7.2
See https://nodejs.org/api/crypto.html#crypto_class_hmac. Gives more examples for using the streaming approach.
As others have answered, you need multiple ALTER TABLE
statements.
Try following:
ALTER TABLE tblcommodityOHLC alter column CC_CommodityContractID NUMERIC(18,0);
ALTER TABLE tblcommodityOHLC alter column CM_CommodityID NUMERIC(18,0);
It's an old question, however might be useful for someone like me.
lodash
has _.inRange()
function https://lodash.com/docs/4.17.4#inRange
Example:
_.inRange(3, 2, 4);
// => true
Please note that this method utilizes the Lodash
utility library, and requires access to an installed version of Lodash.
I achieved this with in XML with
android:background="@android:color/transparent"
I have created a util service for my angular application. It have two function which use very often.
For example you have object.
First getting value from object recursively without throwing undefined error.
{prop: { nestedProp1: {nestedProp2: somevalue}}}; get nestedProp2 2 without undefined checks.
Second filter array on basis
[{prop: { nestedProp1: {nestedProp2: somevalue1}}}, {prop: { nestedProp1: {nestedProp2: somevalue2}}}];
Find object from array with nestedProp2=somevalue2
app.service('UtilService', function(httpService) {
this.mapStringKeyVal = function(map, field) {
var lastIdentifiedVal = null;
var parentVal = map;
field.split('.').forEach(function(val){
if(parentVal[val]){
lastIdentifiedVal = parentVal[val];
parentVal = parentVal[val];
}
});
return lastIdentifiedVal;
}
this.arrayPropFilter = function(array, field,value) {
var lastIdentifiedVal = null;
var mapStringKeyVal = this.mapStringKeyVal;
array.forEach(function(arrayItem){
var valueFound = mapStringKeyVal(arrayItem,field);
if(!lastIdentifiedVal && valueFound && valueFound==value){
lastIdentifiedVal = arrayItem;
}
});
return lastIdentifiedVal;
}});
For solution for current question. inject UtilService and call,
UtilService.arrayPropFilter(purposeArray,'purpose','daily');
Or more advanced
UtilService.arrayPropFilter(purposeArray,'purpose.nestedProp1.nestedProp2','daily');
I believe for @Service
you have to add qualifier name like below :
@Service("employeeService")
should solve your issue
or after @Service
you should add @Qualifier
annontion like below :
@Service
@Qualifier("employeeService")
Both setInterval
and setTimeout
can work for you (as @Doug Neiner and @John Boker wrote both now point to setInterval
).
See here for some more explanation about both to see which suites you most and how to stop each of them.
Here's another way to drop a default constraint with an unknown name without having to first run a separate query to get the constraint name:
DECLARE @ConstraintName nvarchar(200)
SELECT @ConstraintName = Name FROM SYS.DEFAULT_CONSTRAINTS
WHERE PARENT_OBJECT_ID = OBJECT_ID('__TableName__')
AND PARENT_COLUMN_ID = (SELECT column_id FROM sys.columns
WHERE NAME = N'__ColumnName__'
AND object_id = OBJECT_ID(N'__TableName__'))
IF @ConstraintName IS NOT NULL
EXEC('ALTER TABLE __TableName__ DROP CONSTRAINT ' + @ConstraintName)
Check out from dateutil.relativedelta import *
for adding a specific amount of time to a date, you can continue to use timedelta
for the simple stuff i.e.
use_date = use_date + datetime.timedelta(minutes=+10)
use_date = use_date + datetime.timedelta(hours=+1)
use_date = use_date + datetime.timedelta(days=+1)
use_date = use_date + datetime.timedelta(weeks=+1)
or you can start using relativedelta
use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(years=+1)
for the last day of next month:
use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
Right now this will provide 29/02/2016
for the penultimate day of next month:
use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
use_date = use_date+relativedelta(days=-1)
last Friday of the next month:
use_date = use_date+relativedelta(months=+1, day=31, weekday=FR(-1))
2nd Tuesday of next month:
new_date = use_date+relativedelta(months=+1, day=1, weekday=TU(2))
As @mrroot5 points out dateutil's rrule
functions can be applied, giving you an extra bang for your buck, if you require date occurences.
for example:
Calculating the last day of the month for 9 months from the last day of last month.
Then, calculate the 2nd Tuesday for each of those months.
from dateutil.relativedelta import *
from dateutil.rrule import *
from datetime import datetime
use_date = datetime(2020,11,21)
#Calculate the last day of last month
use_date = use_date+relativedelta(months=-1)
use_date = use_date+relativedelta(day=31)
#Generate a list of the last day for 9 months from the calculated date
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, bymonthday=(-1,)))
print("Last day")
for ld in x:
print(ld)
#Generate a list of the 2nd Tuesday in each of the next 9 months from the calculated date
print("\n2nd Tuesday")
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, byweekday=TU(2)))
for tuesday in x:
print(tuesday)

A simple one liner:
public static string Combine(this string uri1, string uri2) => $"{uri1.TrimEnd('/')}/{uri2.TrimStart('/')}";
Inspired by @Matt Sharpe's answer.
My suggestion is to use a function. But rather than putting the if
in the function, which you might be tempted to do, do it like this:
if verbose:
def verboseprint(*args):
# Print each argument separately so caller doesn't need to
# stuff everything to be printed into a single string
for arg in args:
print arg,
print
else:
verboseprint = lambda *a: None # do-nothing function
(Yes, you can define a function in an if
statement, and it'll only get defined if the condition is true!)
If you're using Python 3, where print
is already a function (or if you're willing to use print
as a function in 2.x using from __future__ import print_function
) it's even simpler:
verboseprint = print if verbose else lambda *a, **k: None
This way, the function is defined as a do-nothing if verbose mode is off (using a lambda), instead of constantly testing the verbose
flag.
If the user could change the verbosity mode during the run of your program, this would be the wrong approach (you'd need the if
in the function), but since you're setting it with a command-line flag, you only need to make the decision once.
You then use e.g. verboseprint("look at all my verbosity!", object(), 3)
whenever you want to print a "verbose" message.
There's a convenient method for this in MySql called GROUP_CONCAT. An equivalent for SQL Server doesn't exist, but you can write your own using the SQLCLR. Luckily someone already did that for you.
Your query then turns into this (which btw is a much nicer syntax):
SELECT CUSTOMFIELD, ISSUE, dbo.GROUP_CONCAT(STRINGVALUE)
FROM Jira.customfieldvalue
WHERE CUSTOMFIELD = 12534 AND ISSUE = 19602
GROUP BY CUSTOMFIELD, ISSUE
But please note that this method is good for at the most 100 rows within a group. Beyond that, you'll have major performance problems. SQLCLR aggregates have to serialize any intermediate results and that quickly piles up to quite a lot of work. Keep this in mind!
Interestingly the FOR XML
doesn't suffer from the same problem but instead uses that horrendous syntax.
Several pointers:
You need to handle a return value of 0, which tells you that the remote host closed the socket.
For nonblocking sockets, you also need to check an error return value (-1) and make sure that errno isn't EINPROGRESS, which is expected.
You definitely need better error handling - you're potentially leaking the buffer pointed to by 'buffer'. Which, I noticed, you don't allocate anywhere in this code snippet.
Someone else made a good point about how your buffer isn't a null terminated C string if your read() fills the entire buffer. That is indeed a problem, and a serious one.
Your buffer size is a bit small, but should work as long as you don't try to read more than 256 bytes, or whatever you allocate for it.
If you're worried about getting into an infinite loop when the remote host sends you a malformed message (a potential denial of service attack) then you should use select() with a timeout on the socket to check for readability, and only read if data is available, and bail out if select() times out.
Something like this might work for you:
fd_set read_set;
struct timeval timeout;
timeout.tv_sec = 60; // Time out after a minute
timeout.tv_usec = 0;
FD_ZERO(&read_set);
FD_SET(socketFileDescriptor, &read_set);
int r=select(socketFileDescriptor+1, &read_set, NULL, NULL, &timeout);
if( r<0 ) {
// Handle the error
}
if( r==0 ) {
// Timeout - handle that. You could try waiting again, close the socket...
}
if( r>0 ) {
// The socket is ready for reading - call read() on it.
}
Depending on the volume of data you expect to receive, the way you scan the entire message repeatedly for the "end;" token is very inefficient. This is better done with a state machine (the states being 'e'->'n'->'d'->';') so that you only look at each incoming character once.
And seriously, you should consider finding a library to do all this for you. It's not easy getting it right.
Per the official guide, use of
pylab
is no longer recommended.matplotlib.pyplot
should be used directly instead.
Globally setting font sizes via rcParams
should be done with
import matplotlib.pyplot as plt
plt.rcParams['axes.labelsize'] = 16
plt.rcParams['axes.titlesize'] = 16
# or
params = {'axes.labelsize': 16,
'axes.titlesize': 16}
plt.rcParams.update(params)
# or
import matplotlib as mpl
mpl.rc('axes', labelsize=16, titlesize=16)
# or
axes = {'labelsize': 16,
'titlesize': 16}
mpl.rc('axes', **axes)
The defaults can be restored using
plt.rcParams.update(plt.rcParamsDefault)
You can also do this by creating a style sheet in the stylelib
directory under the matplotlib configuration directory (you can get your configuration directory from matplotlib.get_configdir()
). The style sheet format is
axes.labelsize: 16
axes.titlesize: 16
If you have a style sheet at /path/to/mpl_configdir/stylelib/mystyle.mplstyle
then you can use it via
plt.style.use('mystyle')
# or, for a single section
with plt.style.context('mystyle'):
# ...
You can also create (or modify) a matplotlibrc file which shares the format
axes.labelsize = 16
axes.titlesize = 16
Depending on which matplotlibrc file you modify these changes will be used for only the current working directory, for all working directories which do not have a matplotlibrc file, or for all working directories which do not have a matplotlibrc file and where no other matplotlibrc file has been specified. See this section of the customizing matplotlib page for more details.
A complete list of the rcParams
keys can be retrieved via plt.rcParams.keys()
, but for adjusting font sizes you have (italics quoted from here)
axes.labelsize
- Fontsize of the x and y labelsaxes.titlesize
- Fontsize of the axes titlefigure.titlesize
- Size of the figure title (Figure.suptitle()
)xtick.labelsize
- Fontsize of the tick labelsytick.labelsize
- Fontsize of the tick labelslegend.fontsize
- Fontsize for legends (plt.legend()
, fig.legend()
)legend.title_fontsize
- Fontsize for legend titles, None
sets to the same as the default axes. See this answer for usage example.all of which accept string sizes {'xx-small', 'x-small', 'smaller', 'small', 'medium', 'large', 'larger', 'x-large', 'xxlarge'}
or a float
in pt
. The string sizes are defined relative to the default font size which is specified by
font.size
- the default font size for text, given in pts. 10 pt is the standard valueAdditionally, the weight can be specified (though only for the default it appears) by
font.weight
- The default weight of the font used by text.Text

(700), 'lighter'
, and 'bolder'
(relative with respect to current weight).Giving complete Solution

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)
Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....
However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.
As you're partially working on Linux and Windows, make sure core.eol
is set to native
and core.autocrlf
is set to true
.
Then, replace the content of your .gitattributes
file with the following
* text=auto
This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.
However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.
Provided you work on a C based image processing project, replace the content of your .gitattributes
file with the following
* text=auto
*.txt text
*.c text
*.h text

This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.
In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.
As a real world example, you can also peek at this commit where those changes to a .gitattributes
file are demonstrated.
UPDATE to the answer considering the following comment
I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory
Makes sense. Thanks for the clarification. In this specific context, the .gitattributes
file by itself won't be enough.
Run the following commands against your repository
$ git config core.eol lf
$ git config core.autocrlf input
As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol
will make sure text files bear LF line endings on checkouts. core.autocrlf
will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.
Optionally, you can help Git distinguish what is a text file by creating a .gitattributes
file containing something similar to the following:
# Autodetect text files
* text=auto
# ...Unless the name matches the following
# overriding patterns
# Definitively text files
*.txt text
*.c text
*.h text
# Ensure those won't be messed up with
*.jpg binary
*.data binary
If you decided to create a .gitattributes
file, commit it.
Lastly, ensure git status
mentions "nothing to commit (working directory clean)", then perform the following operation
$ git checkout-index --force --all
This will recreate your files in your working directory, taking into account your config changes and the .gitattributes
file and replacing any potential overlooked CRLF in your text files.
Once this is done, every text file in your working directory WILL bear LF line endings and git status
should still consider the workdir as clean.
Sometimes, a row contain double quote column. When csv reader try read this row, not understood end of column and fire this raise. Solution is below:
reader = csv.reader(cf, quoting=csv.QUOTE_MINIMAL)
404 Not Found technically means that uri does not currently map to a resource. In your example, I interpret a request to http://mywebsite/api/user/13
that returns a 404 to imply that this url was never mapped to a resource. To the client, that should be the end of conversation.
To address concerns with ambiguity, you can enhance your API by providing other response codes. For example, suppose you want to allow clients to issue GET requests the url http://mywebsite/api/user/13
, you want to communicate that clients should use the canonical url http://mywebsite/restapi/user/13
. In that case, you may want to consider issuing a permanent redirect by returning a 301 Moved Permanently and supply the canonical url in the Location header of the response. This tells the client that for future requests they should use the canonical url.
Support for multi-root workspaces is now enabled by default in the latest stable release [November 2017 release].
The File > Add Folder to Workspace
command brings up an Open Folder dialog to select the new folder.
Ignore is exactly what the name implies.
It doesn't "throw away" something you don't need instead, it ignores the amount of characters you specify when you call it, up to the char you specify as a breakpoint.
It works with both input and output buffers.
Essentially, for std::cin
statements you use ignore before you do a getline
call, because when a user inputs something with std::cin
, they hit enter and a '\n'
char gets into the cin
buffer. Then if you use getline
, it gets the newline char instead of the string you want. So you do a std::cin.ignore(1000,'\n')
and that should clear the buffer up to the string that you want. (The 1000 is put there to skip over a specific amount of chars before the specified break point, in this case, the \n newline character.)
Plugin: jquery-ui-autocomplete-scroll with scroller and limit results are beautiful

Use std::cout
, since cout
is defined within the std
namespace. Alternatively, add a using std::cout;
directive.
I had the same problem earlier today. I could not figure out why the class file I was trying to reference was not being seen by the compiler. I had recently changed the namespace of the class file in question to a different but already existing namespace. (I also had using references to the class's new and previous namespaces where I was trying to instantiate it)
Where the compiler was telling me I was missing a reference when trying to instantiate the class, I right clicked and hit "generate class stub". Once Visual Studio generated a class stub for me, I coped and pasted the code from the old class file into this stub, saved the stub and when I tried to compile again it worked! No issues.
Might be a solution specific to my build, but its worth a try.
For example the first one below uses absolute paths :
(this is from inside the folder which contains the repository and the backup as subfolders. also remember that the backup folder is not modified if it already contains anything. and if it is not present, a new folder will be created )
~/git$ git clone --no-hardlinks ~/git/git_test1/ ~/git/bkp_repos/
The following uses relative paths :
~/git$ git clone --no-hardlinks git_test1/ bkp_repos2/
If you want to use $.getJSON()
you can add the following before the call :
$.ajaxSetup({
scriptCharset: "utf-8",
contentType: "application/json; charset=utf-8"
});
You can use the charset you want instead of utf-8
.
The options are explained here.
contentType :
When sending data to the server, use this content-type
. Default is application/x-www-form-urlencoded
, which is fine for most cases.
scriptCharset :
Only for requests with jsonp
or script
dataType and GET type. Forces the request to be interpreted as a certain charset. Only needed for charset differences between the remote and local content.
You may need one or both ...
You could create a function to kill all existing sessions. take a look at Kill all detached screen sessions
to list all active sessions use screen -r
when listed, select with your mouse the session you are interested in and paste it. like this
screen -r
PRINT DATEDIFF(second,'2010-01-22 15:29:55.090','2010-01-22 15:30:09.153')
The accepted answer did not work for me when using Django 1.4.4. Instead of the raw query, a reference to the Query object was returned: <django.db.models.sql.query.Query object at 0x10a4acd90>
.
The following returned the query:
>>> queryset = MyModel.objects.all()
>>> queryset.query.__str__()
This is a terrible way to do it but it avoids creating a definition. It fulfills the requirement to stick with the basic Python3 library.
# Adjust from UST to Eastern Standard Time (dynamic)
# df.my_localtime should already be in datetime format, so just in case
df['my_localtime'] = pd.to_datetime.df['my_localtime']
df['my_localtime'] = df['my_localtime'].dt.tz_localize('UTC').dt.tz_convert('America/New_York').astype(str)
df['my_localtime'] = pd.to_datetime(df.my_localtime.str[:-6])
List<Person> roster = ...;
Map<String, Person> map =
roster
.stream()
.collect(
Collectors.toMap(p -> p.getLast(), p -> p)
);
that would be the translation, but i havent run this or used the API. most likely you can substitute p -> p, for Function.identity(). and statically import toMap(...)
This is the only comprehensive and reliable way I've found to do this.
Assume you want to merge "tag_1.0" into "mybranch".
$git checkout tag_1.0 (will create a headless branch)
$git branch -D tagbranch (make sure this branch doesn't already exist locally)
$git checkout -b tagbranch
$git merge -s ours mybranch
$git commit -am "updated mybranch with tag_1.0"
$git checkout mybranch
$git merge tagbranch
I've used this solution to get what you need.
Let'say that in my .aspx code there's a select list runat="server":
<select id="testSelect" runat="server" ClientIDMode="Static" required>
<option value="1">One</option>
<option value="2">Two</option>
</select>
In my C# code I used the code below to retrieve the text and also value of the options:
testSelect.SelectedIndex == 0 ? "uninformed" :
testSelect.Items[testSelect.SelectedIndex].Text);
In this case I check if the user selected any of the options. If there's nothing selected I show the text as "uninformed".
Because I have just implemented it:
In Groovy
/Grails
it would be:
def locale = Locale.getAvailableLocales().find { availableLocale ->
return availableLocale.toString().equals(searchedLocale)
}
I used setLogLevel(LogLevel.FULL).setLog(new AndroidLog("YOUR_LOG_TAG"))
, it helped me.
UPDATE.
You can also try for debug purpose use retrofit.client.Response
as response model
You'll have to use a favicon for your page.
put this in the head-tag:
<link rel="shortcut icon" href="/favicon.png" type="image/png">
where favicon.png is preferably a 16x16 png image.
I got this on WatchOS Sim. The issue persisted even after:
...and was finally fixed by "Erase all Content and Settings" in the simulator.
Check this:
The TEXTAREA element creates a multi-line text input control
I think you could use a similar answer I gave. You can find it here... https://stackoverflow.com/a/19083993/2063096
Note: This solution does NOT use jQuery UI, there is also a fiddle so you can play around to your liking before implementing it in your code.
The scanner can also use delimiters other than whitespace.
Easy example from Scanner API:
String input = "1 fish 2 fish red fish blue fish";
// \\s* means 0 or more repetitions of any whitespace character
// fish is the pattern to find
Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
System.out.println(s.nextInt()); // prints: 1
System.out.println(s.nextInt()); // prints: 2
System.out.println(s.next()); // prints: red
System.out.println(s.next()); // prints: blue
// don't forget to close the scanner!!
s.close();
The point is to understand the regular expressions (regex
) inside the Scanner::useDelimiter
. Find an useDelimiter
tutorial here.
To start with regular expressions here you can find a nice tutorial.
abc… Letters
123… Digits
\d Any Digit
\D Any Non-digit character
. Any Character
\. Period
[abc] Only a, b, or c
[^abc] Not a, b, nor c
[a-z] Characters a to z
[0-9] Numbers 0 to 9
\w Any Alphanumeric character
\W Any Non-alphanumeric character
{m} m Repetitions
{m,n} m to n Repetitions
* Zero or more repetitions
+ One or more repetitions
? Optional character
\s Any Whitespace
\S Any Non-whitespace character
^…$ Starts and ends
(…) Capture Group
(a(bc)) Capture Sub-group
(.*) Capture all
(ab|cd) Matches ab or cd
I wrote this script for switching DNS servers of all currently enabled interfaces to specific address:
@echo off
:: Google DNS
set DNS1=8.8.8.8
set DNS2=8.8.4.4
for /f "tokens=1,2,3*" %%i in ('netsh int show interface') do (
if %%i equ Enabled (
echo Changing "%%l" : %DNS1% + %DNS2%
netsh int ipv4 set dns name="%%l" static %DNS1% primary validate=no
netsh int ipv4 add dns name="%%l" %DNS2% index=2 validate=no
)
)
ipconfig /flushdns
:EOF
Regular Expression for 0 to 100 with the decimal point.
^100(\.[0]{1,2})?|([0-9]|[1-9][0-9])(\.[0-9]{1,2})?$
I wanted to replace only a part of the url, and with this solution, I don't have to pass the whole url, just the dynamic part:
public interface APIService {
@GET("users/{user_id}/playlists")
Call<List<Playlist> getUserPlaylists(@Path(value = "user_id", encoded = true) String userId);
}
//get the main handle and remove it
//whatever remains is the child pop up window handle
String mainHandle = driver.getWindowHandle();
Set<String> allHandles = driver.getWindowHandles();
Iterator<String> iter = allHandles.iterator();
allHandles.remove(mainHandle);
String childHandle=iter.next();
I'm using
Django 2.2
and got the same error while connecting to sql-server 2012. Spent lot of time to solve this issue and finally this worked.
I changed
'driver': 'ODBC Driver 13 for SQL Server'
to
'driver': 'SQL Server Native Client 11.0'
and it worked.
I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.
The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.
I think this solution is easier and better, use directly the function findstr:
alias | findstr -i Write
You can also make an alias to use grep word:
new-alias grep findstr
First check To see how many aliases you have and what are they, you can initiate this command git remote -v
Then see in which repository you are in then try git remote set-url --add [Then your repositpory link] git push -u origin master
You need to use runat="server"
like this:
<textarea id="TextArea1" cols="20" rows="2" runat="server"></textarea>
You can use the runat=server attribute with any standard HTML element, and later use it from codebehind.
I use sqlite to do this. I find it very, very useful for creating scratch/test databases.
