well looking for a simpler variation I found this:
it's truly smart, and I guess you might want to add other browsers variations too although it worked for me both on Chrome and Firefox.

Below is a minimal code to achieve the effect.
This also works responsively since the border-radius
is in percentage.
.semi-circle{_x000D_
width: 200px;_x000D_
height: 100px;_x000D_
border-radius: 50% 50% 0 0 / 100% 100% 0 0;_x000D_
border: 10px solid #000;_x000D_
border-bottom: 0;_x000D_
}
_x000D_
<div class="semi-circle"></div>

Please note that the problem is not white
color. It is because it is being transparent.
When an element is made transparent, all of its child element's opacity; alpha filter in IE 6 7 etc, is changed to the new value.
So you cannot say that it is white!
You can place an element above it, and change that element's transparency to 1
while changing the image's transparency to .2
or what so ever you want to.
This thread is old, but for those who come from google, Ive come with a solutions that is hybrid from all the answers Ive found on the net.
This will make sure level class is being added:
$(document).on('show.bs.modal', '.modal', function (event) {
$(this).addClass(`modal-level-${$('.modal:visible').length}`);
});
Inside my SCSS Ive wrote a rule that supports main modal and 10 on top (10 because from z-index: 1060
popover takes place), you can add levels count inside _variables.scss
if you want:
@for $level from 0 through 10 {
.modal-level-#{$level} {
z-index: $zindex-modal + $level;
& + .modal-backdrop {
z-index: $zindex-modal + $level - 1;
}
}
}
Do not forget that you cannot have modal inside modal as their controls will be messed up. In my case all my modals were at the end of body
.
And finally as members below also mentions this, after closing one modal, you need to keep modal-open
class on body
:
$(document).on('hidden.bs.modal', function (e) {
if ($('.modal:visible').length > 0) {
$('body').addClass('modal-open');
}
});
Some good answers, but the problem with all solutions I have tried is that the images doesn´t fade into each other. Instead the first one fades completely out and than the next one fades in.
After a few hours of testing a found this sollution. Thx to http://www.1squarepear.com/adding-a-responsive-bootstrap-image-carousel-that-fades-instead-of-slides/
Add this in the css:
.carousel.fade {
opacity: 1;
}
.carousel.fade .item {
transition: opacity ease-out .7s;
left: 0;
opacity: 0; /* hide all slides */
top: 0;
position: absolute;
width: 100%;
display: block;
}
.carousel.fade .item:first-child {
top: auto;
opacity: 1; /* show first slide */
position: relative;
}
.carousel.fade .item.active {
opacity: 1;
}
body {
margin: 0;
padding: 0;
background: url('img/background.jpg') repeat;
}
body:before {
content: " ";
width: 100%;
height: 100%;
position: absolute;
z-index: -1;
top: 0;
left: 0;
background: -webkit-radial-gradient(top center, ellipse cover, rgba(255,255,255,0.2) 0%,rgba(0,0,0,0.5) 100%);
}
PLEASE NOTE: This only using webkit so it will only work in webkit browsers.
try :
-moz-linear-gradient = (Firefox)
-ms-linear-gradient = (IE)
-o-linear-gradient = (Opera)
-webkit-linear-gradient = (Chrome & safari)
Functional Approach for ES6+
If you want to take a more functional approach to iterating over the Map
object, you can do something like this
const myMap = new Map()
myMap.forEach((value, key) => {
console.log(value, key)
})
use android:theme="@android:style/Theme.NoTitleBar
in manifest file's application tag to remove the title bar for whole application or put it in activity tag to remove the title bar from a single activity screen.
Just to add my answer, it seems that the transitions need to be based on initial values and final values within the css properties to be able to manage the animation.
Those reworked css classes should provide the expected result :
.box{_x000D_
position: relative; _x000D_
top:0px;_x000D_
left:0px;_x000D_
width:0px;_x000D_
}_x000D_
_x000D_
.box:hover .hidden{_x000D_
opacity: 1;_x000D_
width: 500px;_x000D_
}_x000D_
_x000D_
.box .hidden{ _x000D_
background: yellow;_x000D_
height: 300px; _x000D_
position: absolute; _x000D_
top: 0px;_x000D_
left: 0px; _x000D_
width: 0px;_x000D_
opacity: 0; _x000D_
transition: all 1s ease;_x000D_
}
_x000D_
<div class="box">_x000D_
_x000D_
<a href="#">_x000D_
<img src="http://farm9.staticflickr.com/8207/8275533487_5ebe5826ee.jpg"></a>_x000D_
<div class="hidden"></div>_x000D_

</div>

Let me make a conclusion. In Swift 5
You can choose to addSubview to keyWindow, if you add the view in the last. Otherwise, you can bringSubViewToFront.
let view = UIView()
UIApplication.shared.keyWindow?.addSubview(view)
UIApplication.shared.keyWindow?.bringSubviewToFront(view)
You can also set the zPosition. But the drawback is that you can not change the gesture responding order.
view.layer.zPosition = 1
html, body {
height: 100%;
width: 100%;
}
html {
display: table;
margin: auto;
}
body {
padding-top: 50px;
display: table-cell;
}
div {
margin: auto;
}
This will center align objects and then also center align the items within them to center align multiple objects with different widths.
First set the opacity explicitly in your HTML thus:
<div id="box" style="height:150px; width:150px; background-color:orange; margin:25px; opacity:1"></div>
otherwise it is 0 or null
this is then in my .js file
document.getElementById("fadeButton90").addEventListener("click", function(){
document.getElementById("box").style.opacity = document.getElementById("box").style.opacity*0.90; });
This is very important question and I was struggling to get it done (show/hide) message by replacing current and add new message.
Below is working example:
function showAndDismissAlert(type, message) {_x000D_
_x000D_
var htmlAlert = '<div class="alert alert-' + type + '">' + message + '</div>';_x000D_
$(".alert-messages").prepend(htmlAlert);_x000D_
$(".alert-messages .alert").hide().fadeIn(600).delay(2000).fadeOut(1000, function() {_x000D_
$(this).remove();_x000D_
});_x000D_
_x000D_
}

Hope it will help others!
Here is my solution using AnimatorSet which seems to be a bit more reliable than AnimationSet.
// Custom animation on image
ImageView myView = (ImageView)splashDialog.findViewById(R.id.splashscreenImage);
ObjectAnimator fadeOut = ObjectAnimator.ofFloat(myView, "alpha", 1f, .3f);
fadeOut.setDuration(2000);
ObjectAnimator fadeIn = ObjectAnimator.ofFloat(myView, "alpha", .3f, 1f);
fadeIn.setDuration(2000);
final AnimatorSet mAnimationSet = new AnimatorSet();
mAnimationSet.play(fadeIn).after(fadeOut);
mAnimationSet.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
mAnimationSet.start();
}
});
mAnimationSet.start();
Solved my problem by adding this to my ListView
:
android:scrollbars="none"
You can do this simply like this
$('#image_id').click(function() {
$("#some_id iframe").attr('src', $("#some_id iframe", parent).attr('src') + '?autoplay=1');
});
where image_id is your image id you are clicking and some_id is id of div in which iframe is also you can use iframe id directly.
I hope my script help you.
<i class="mostrar-producto">mostrar...</i>
<div class="producto" style="display:none;position: absolute;">Producto</div>
My script
<script>
$(".mostrar-producto").mouseover(function(){
$(".producto").fadeIn();
});
$(".mostrar-producto").mouseleave(function(){
$(".producto").fadeOut();
});
</script>
Just use That.Its Easy.
<script language="javascript" type="text/javascript">
var images = new Array()
images[0] = "img1.jpg";
images[1] = "img2.jpg";
images[2] = "img3.jpg";
setInterval("changeImage()", 30000);
var x=0;
function changeImage()
{
document.getElementById("img").src=images[x]
x++;
if (images.length == x)
{
x = 0;
}
}
</script>
And in Body Write this Code:-
<img id="img" src="imgstart.jpg">
Update: I figured this out. On my ScrollView, I needed to override the onInterceptTouchEvent method to only intercept the touch event if the Y motion is > the X motion. It seems like the default behavior of a ScrollView is to intercept the touch event whenever there is ANY Y motion. So with the fix, the ScrollView will only intercept the event if the user is deliberately scrolling in the Y direction and in that case pass off the ACTION_CANCEL to the children.
Here is the code for my Scroll View class that contains the HorizontalScrollView:
public class CustomScrollView extends ScrollView {
private GestureDetector mGestureDetector;
public CustomScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
mGestureDetector = new GestureDetector(context, new YScrollDetector());
setFadingEdgeLength(0);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
}
// Return false if we're scrolling in the x direction
class YScrollDetector extends SimpleOnGestureListener {
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
return Math.abs(distanceY) > Math.abs(distanceX);
}
}
}
this is not the very clean and smart way but its very easy to understand and use somtimes - its like odd and even - boolean like:
var moreOrLess = 2;
$('.Btn').on('click',function(){
if(moreOrLess % 2 == 0){
$(this).text('text1');
moreOrLess ++ ;
}else{
$(this).text('more');
moreOrLess ++ ;
}
});
if its something you wish to switch, fading one out and fading another in the same place, you can place a {position:absolute} attribute on the divs, so both the animations play on top of one another, and you don't have to wait for one animation to be over before starting up the next.

I disagree with the recommendation to create separate CSS files for non-editorial images.
Assuming the images are for UI purposes, it's presentation layer styling, and as mentioned above, if you're doing mobile UI's its definitely a good idea to keep all styling in a single file so it can be cached once.
I had used JCL about 2 years back so cannot write a code for you but here is the idea;
again i apologize for solution without code, but i am out of touch by 2 yrs+
To change the size of (almost) all text elements, in one place, and synchronously, rel()
is quite efficient:
g+theme(text = element_text(size=rel(3.5))
You might want to tweak the number a bit, to get the optimum result. It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. One exception is faceted grids' titles which must be manually set to the same value, for example if both x and y facets are used in a graph:
theme(text = element_text(size=rel(3.5)),
strip.text.x = element_text(size=rel(3.5)),
strip.text.y = element_text(size=rel(3.5)))
The main reason for primary and foreign keys is to enforce data consistency.
A primary key enforces the consistency of uniqueness of values over one or more columns. If an ID column has a primary key then it is impossible to have two rows with the same ID value. Without that primary key, many rows could have the same ID value and you wouldn't be able to distinguish between them based on the ID value alone.
A foreign key enforces the consistency of data that points elsewhere. It ensures that the data which is pointed to actually exists. In a typical parent-child relationship, a foreign key ensures that every child always points at a parent and that the parent actually exists. Without the foreign key you could have "orphaned" children that point at a parent that doesn't exist.
This will also happen if you are trying to insert into a unique constraint situation, ie if you can only have one type of address per employer and you try to insert a second of that same type with the same employer, you will get the same problem.
OR
This could also happen if all of the object properties that were assigned to, they were assigned with the same values as they had before.
using(var db = new MyContext())
{
var address = db.Addresses.FirstOrDefault(x => x.Id == Id);
address.StreetAddress = StreetAddress; // if you are assigning
address.City = City; // all of the same values
address.State = State; // as they are
address.ZipCode = ZipCode; // in the database
db.SaveChanges(); // Then this will throw that exception
}
For Chrome 66 I found the relevant option under:
Using a new Incognito window is probably easier, but for those times you forget and want to clear the saved password, this does the trick without having to restart Chrome (which also works)
What about position: relative
for the outer div? In the example that hides the inner one. It also won't move it in its layout since you don't specify a top or left.
If you have an text/textarea attribute named my_attr you can get it by:
product->getMyAttr();
Another easy alternative:
Since $PWD
will usually contain a slash /
, use |
instead of /
for the sed statement:
sed -e "s|xxx|$PWD|"
The answer depends on a lot of things like:
I suggest that you take a look at the Merkle-Damgard family of hash functions like SHA-1 etc
You could use .test() which returns a boolean value when is find what your looking for in another string:
var thisExpressions = [ '/something/', '/something_else/', '/and_something_else/'];
var thisString = new RegExp('\\b' + 'else' + '\\b', 'i');
var FoundIt = thisString.test(thisExpressions);
if (FoundIt) { /* DO STUFF */ }
The simplest way of finding factors of a number:
def factors(x):
return [i for i in range(1,x+1) if x%i==0]
There is nothing a Factory cannot do or does better in comparison with a Service. And vice verse. Factory just seems to be more popular. The reason for that is its convenience in handling private/public members. Service would be more clumsy in this regard. When coding a Service you tend to make your object members public via “this” keyword and may suddenly find out that those public members are not visible to private methods (ie inner functions).
var Service = function(){
//public
this.age = 13;
//private
function getAge(){
return this.age; //private does not see public
}
console.log("age: " + getAge());
};
var s = new Service(); //prints 'age: undefined'
Angular uses the “new” keyword to create a service for you, so the instance Angular passes to the controller will have the same drawback. Of course you may overcome the problem by using this/that:
var Service = function(){
var that = this;
//public
this.age = 13;
//private
function getAge(){
return that.age;
}
console.log("age: " + getAge());
};
var s = new Service();// prints 'age: 13'
But with a large Service constant this\that-ing would make the code poorly readable. Moreover, the Service prototypes will not see private members – only public will be available to them:
var Service = function(){
var name = "George";
};
Service.prototype.getName = function(){
return this.name; //will not see a private member
};
var s = new Service();
console.log("name: " + s.getName());//prints 'name: undefined'
Summing it up, using Factory is more convenient. As Factory does not have these drawbacks. I would recommend using it by default.
Not quite sure why everyone is giving you a hard time for wanting to do this - there are several scenarios where you'd want a fixed size initialised list. And you've correctly deduced that arrays are sensible in these cases.
import array
verts=array.array('i',(0,)*1000)
For the non-pythonistas, the (0,)*1000
term is creating a tuple containing 1000 zeros. The comma forces python to recognise (0)
as a tuple, otherwise it would be evaluated as 0.
I've used a tuple instead of a list because they are generally have lower overhead.
I believe IE requires the H.264 or MPEG-4 codec, which it seems like you don't specify/include. You can always check for browser support by using HTML5Please and Can I use.... Both sites usually have very up-to-date information about support, polyfills, and advice on how to take advantage of new technology.
Separation of concerns is the biggy.
Being able to tease these components apart makes the code easier to re-use and independently test. If you don't actually know what MVC is, be careful about trying to understand people's opinions as there is still some contention about what the "Model" is (whether it is the business objects/DataSets/DataTables or if it represents the underlying service layer).
I've seen all sorts of implementations that call themselves MVC but aren't exactly and as the comments in Jeff's article show MVC is a contentious point that I don't think developers will ever fully agree upon.
A good round up of all of the different MVC types is available here.
I know that this is old post but someone can help:
function POST($index, $default=NULL){
if(isset($_POST[$index]))
{
if(!empty(trim($_POST[$index])))
return $_POST[$index];
}
return $default;
}
This code above are my basic POST function what I use anywhere. Here you can put filters, regular expressions, etc. Is faster and clean. My advanced POST function is more complicate to accept and check arrays, string type, default values etc. Let's your imagination work here.
You easy can check username like this:
$username = POST("username");
if($username!==null){
echo "{$username} is in the house.";
}
Also I added $default
string that you can define some default value if POST is not active or content not exists.
echo "<h1>".POST("title", "Stack Overflow")."</h1>";
Play with it.
It would be easier to make suggestions if you provided example code and data.
Accessing the dictionary is unlikely to be a problem as that operation is O(1) on average, and O(N) amortized worst case. It's possible that the built-in hashing functions are experiencing collisions for your data. If you're having problems with has the built-in hashing function, you can provide your own.
Python's dictionary implementation reduces the average complexity of dictionary lookups to O(1) by requiring that key objects provide a "hash" function. Such a hash function takes the information in a key object and uses it to produce an integer, called a hash value. This hash value is then used to determine which "bucket" this (key, value) pair should be placed into.
You can overwrite the __hash__ method in your class to implement a custom hash function like this:
def __hash__(self):
return hash(str(self))
Depending on what your data actually looks like, you might be able to come up with a faster hash function that has fewer collisions than the standard function. However, this is unlikely. See the Python Wiki page on Dictionary Keys for more information.
Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)
import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1
u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0
#option 1
#keep index of t
u.index = t.index
#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)
#now concat will keep number of rows
r=pd.concat([t,u], axis=1)
Update your SP and handle exception in it using declare handler with get diagnostics so that you will know if there is an exception. e.g.
CREATE DEFINER=`root`@`localhost` PROCEDURE `validar_egreso`(
IN codigo_producto VARCHAR(100),
IN cantidad INT,
OUT valido INT(11)
)
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
GET DIAGNOSTICS CONDITION 1
@p1 = RETURNED_SQLSTATE, @p2 = MESSAGE_TEXT;
SELECT @p1, @p2;
END
DECLARE resta INT(11);
SET resta = 0;
SELECT (s.stock - cantidad) INTO resta
FROM stock AS s
WHERE codigo_producto = s.codigo;
IF (resta > s.stock_minimo) THEN
SET valido = 1;
ELSE
SET valido = -1;
END IF;
SELECT valido;
END
That's because you defined your own version of name
for your enum, and getByName
doesn't use that.
getByName("COLUMN_HEADINGS")
would probably work.
As others have pointed out setInterval and setTimeout will do the trick. I wanted to highlight a bit more advanced technique that I learned from this excellent video by Paul Irish: http://paulirish.com/2010/10-things-i-learned-from-the-jquery-source/
For periodic tasks that might end up taking longer than the repeat interval (like an HTTP request on a slow connection) it's best not to use setInterval()
. If the first request hasn't completed and you start another one, you could end up in a situation where you have multiple requests that consume shared resources and starve each other. You can avoid this problem by waiting to schedule the next request until the last one has completed:
// Use a named immediately-invoked function expression.
(function worker() {
$.get('ajax/test.html', function(data) {
// Now that we've completed the request schedule the next one.
$('.result').html(data);
setTimeout(worker, 5000);
});
})();
For simplicity I used the success callback for scheduling. The down side of this is one failed request will stop updates. To avoid this you could use the complete callback instead:
(function worker() {
$.ajax({
url: 'ajax/test.html',
success: function(data) {
$('.result').html(data);
},
complete: function() {
// Schedule the next request when the current one's complete
setTimeout(worker, 5000);
}
});
})();
require_once 'lib/Zend/Loader/StandardAutoloader.php';
$loader = new Zend\Loader\StandardAutoloader(array('autoregister_zf' => true));
$loader->registerNamespace('Http\PhpEnvironment', 'lib/Zend/Http');
// Register with spl_autoload:
$loader->register();
$a = new Zend\Http\PhpEnvironment\Request();
print_r($a->getQuery()->get()); exit;
I do not like the echo "..." | awk ...
solution as it calls unnecessary fork
and exec
system calls.
I prefer a Dimitre's solution with a little twist
awk -F\| '{print $3 $2 $1}' <<<'12|23|11'
Or a bit shorter version:
awk -F\| '$0=$3 $2 $1' <<<'12|23|11'
In this case the output record put together which is a true condition, so it gets printed.
In this specific case the stdin
redirection can be spared with setting an awk internal variable:
awk -v T='12|23|11' 'BEGIN{split(T,a,"|");print a[3] a[2] a[1]}'
I used ksh quite a while, but in bash this could be managed by internal string manipulation. In the first case the original string is split by internal terminator. In the second case it is assumed that the string always contains digit pairs separated by a one character separator.
T='12|23|11';echo -n ${T##*|};T=${T%|*};echo ${T#*|}${T%|*}
T='12|23|11';echo ${T:6}${T:3:2}${T:0:2}
The result in all cases is
112312
Another way to do this is using ":after" (pseudo-element) on the element you want to underline.
h2{
position:relative;
display:inline-block;
font-weight:700;
font-family:arial,sans-serif;
text-transform:uppercase;
font-size:3em;
}
h2:after{
content:"";
position:absolute;
left:0;
bottom:0;
right:0;
margin:auto;
background:#000;
height:1px;
}

The difference you see is most likely because you don't zero the hour, minute, second and milliseconds fields of your Calendar
instances: Calendar.getInstance()
gives you the current date and time, just like new Date()
or System.currentTimeMillis()
.
Note that the month field of Calendar is zero-based, i.e. January is 0, not 1.
Also, don't prefix numbers with zero, this might look nice and it even works till you reach 8: 08
isn't a valid numeral in Java. Prefixing numerals with zero makes the compiler assume you're defining them as octal numerals which only works up to 07
(for single digits).
Just drop calendar1
completely (1970-01-01 00:00:00'000 is the begin of the epoch, i.e. zero anyway) and do this:
public long returnSeconds(int year, int month, int date) {
final Calendar cal = Calendar.getInstance();
cal.set(year, month, date, 0, 0, 0);
cal.set(Calendar.MILLISECOND, 0);
return cal.getTimeInMillis() / 1000;
}
The updated or deleted values are stored in DELETED. we can get it by the below method in trigger
Full example,
CREATE TRIGGER PRODUCT_UPDATE ON PRODUCTS
FOR UPDATE
AS
BEGIN
DECLARE @PRODUCT_NAME_OLD VARCHAR(100)
DECLARE @PRODUCT_NAME_NEW VARCHAR(100)
SELECT @PRODUCT_NAME_OLD = product_name from DELETED
SELECT @PRODUCT_NAME_NEW = product_name from INSERTED
END
Doing type('')
is effectively equivalent to str
and types.StringType
so type('') == str == types.StringType
will evaluate to "True
"
Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode)
or assert isinstance(obj, basestring)
, the latter of which was suggested in the comments by 007Brendan and is probably preferred.
isinstance()
is useful if you want to ask whether an object is an instance of a class, e.g:
class MyClass: pass
print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception
But for basic types, e.g. str
, unicode
, int
, float
, long
etc asking type(var) == TYPE
will work OK.
If you want to change tabs to spaces in a lot of files, but don't want to open them individually, I have found that it works equally as well to just use the Find and Replace option from the left-most tools bar.
In the first box (Find
), copy and paste a tab from the source code.
In the second box (Replace
), enter the number of spaces that you wish to use (i.e. 2 or 4).
If you press the ...
button, you can specify directories to include or ignore (i.e. src/Data/Json
).
Finally, inspect the result preview and press Replace All. All files in the workspace may be affected.
You could use a Polygon Clipping algorithm to find the intersection between two polygons. However these tend to be complicated algorithms when all of the edge cases are taken into account.
One implementation of polygon clipping that you can use your favorite search engine to look for is Weiler-Atherton. wikipedia article on Weiler-Atherton
Alan Murta has a complete implementation of a polygon clipper GPC.
Edit:
Another approach is to first divide each polygon into a set of triangles, which are easier to deal with. The Two-Ears Theorem by Gary H. Meisters does the trick. This page at McGill does a good job of explaining triangle subdivision.
If you use Windows (note, we are using printf(), not cout):
//Save As UTF8 without signature
#include <stdio.h>
#include<windows.h>
int main (){
SetConsoleOutputCP(65001);
printf("?\n");
}
Not Unicode but working - 1251 instead of UTF8:
//Save As Windows 1251
#include <iostream>
#include<windows.h>
using namespace std;
int main (){
SetConsoleOutputCP(1251);
cout << "?" << endl;
}
Is there a preformance difference in Javascript between a switch statement and an if...else if....else?
I don't think so, switch
is useful/short if you want prevent multiple if-else
conditions.
Is the behavior of switch and if...else if...else different across browsers? (FireFox, IE, Chrome, Opera, Safari)
Behavior is same across all browsers :)
I found this question, but I think a clear and simple answer is missing.
I don't want to attach my debugger to a process, but I still want to be able to call the service OnStart
and OnStop
methods. I also want it to run as a console application so that I can log information from NLog to a console.
I found these brilliant guides that does this:
Start by changing the projects Output type
to Console Application
.
Change your Program.cs
to look like this:
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
static void Main()
{
// Startup as service.
ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[]
{
new Service1()
};
if (Environment.UserInteractive)
{
RunInteractive(ServicesToRun);
}
else
{
ServiceBase.Run(ServicesToRun);
}
}
}
Then add the following method to allow services running in interactive mode.
static void RunInteractive(ServiceBase[] servicesToRun)
{
Console.WriteLine("Services running in interactive mode.");
Console.WriteLine();
MethodInfo onStartMethod = typeof(ServiceBase).GetMethod("OnStart",
BindingFlags.Instance | BindingFlags.NonPublic);
foreach (ServiceBase service in servicesToRun)
{
Console.Write("Starting {0}...", service.ServiceName);
onStartMethod.Invoke(service, new object[] { new string[] { } });
Console.Write("Started");
}
Console.WriteLine();
Console.WriteLine();
Console.WriteLine(
"Press any key to stop the services and end the process...");
Console.ReadKey();
Console.WriteLine();
MethodInfo onStopMethod = typeof(ServiceBase).GetMethod("OnStop",
BindingFlags.Instance | BindingFlags.NonPublic);
foreach (ServiceBase service in servicesToRun)
{
Console.Write("Stopping {0}...", service.ServiceName);
onStopMethod.Invoke(service, null);
Console.WriteLine("Stopped");
}
Console.WriteLine("All services stopped.");
// Keep the console alive for a second to allow the user to see the message.
Thread.Sleep(1000);
}
I've used gFTP for that.

For finding value use below
if let a = companies["AAPL"] {
// a is the value
}
For traversing through the dictionary
for (key, value) in companies {
print(key,"---", value)
}
Finally for searching key by value you firstly add the extension
extension Dictionary where Value: Equatable {
func findKey(forValue val: Value) -> Key? {
return first(where: { $1 == val })?.key
}
}
Then just call
companies.findKey(val : "Apple Inc")
I had a similar issue, but with no source code to run on Xcode.
So if you want to test an application on a real device with a fake location you should use a VPN application.
There are plenty in the App Store to choose from - free ones without the option to choose a specific country/city and free ones which assign you a random location or asks you to choose from a limited set of default options.

TextView tv = new TextView(this);
tv.setText(String.valueOf(number));
or
tv.setText(""+number);
Replace
volume = (4 / 3) Math.PI * Math.pow(radius, 3);
With:
volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;
If it´s in the global scope it´s better to use:
function foo()
{
alert('foo');
}
var a = 'foo';
window[a]();
than eval()
. Because eval()
is evaaaaaal.
Exactly like Nosredna said 40 seconds before me that is >.<
I spent almost a day trying to figure out why I was getting this exception. After lots of struggle, this config worked perfectly (Kotlin):

intent.setDataAndType(contentUri, mimeType)
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION

I explain the whole process here.
If you're displaying a user-readable file name, you do not want to use lastPathComponent
. Instead, pass the full path to NSFileManager's displayNameAtPath:
method. This basically does does the same thing, only it correctly localizes the file name and removes the extension based on the user's preferences.
Just use <c:url>
-tag with an application context relative path.
When the value
parameter starts with an /
, then the tag will treat it as an application relative url, and will add the application-name to the url.
Example:
jsp:
<c:url value="/templates/style/main.css" var="mainCssUrl" />`
<link rel="stylesheet" href="${mainCssUrl}" />
...
<c:url value="/home" var="homeUrl" />`
<a href="${homeUrl}">home link</a>
will become this html, with an domain relative url:
<link rel="stylesheet" href="/AppName/templates/style/main.css" />
...
<a href="/AppName/home">home link</a>
I'd like to share this little hack:
A click on the Eclipse's icon indicated a problem with the JRE. So, I put this command in the destination field of the icon's properties:
C:\...\eclipse.exe -vm c:\'Program Files'\Java\jdk1.7.0_51\jre\bin\javaw
Thinking that the "'" would solve the problem with the space in the path. That did not function. Then, I tried this command:
C:\...\eclipse.exe -vm c:\Progra~1\Java\jdk1.7.0_51\jre\bin\javaw
with success
try using the cloning technique.
{
DataGridViewRow row = (DataGridViewRow)yourdatagrid.Rows[0].Clone();
// then for each of the values use a loop like below.
int cc = yourdatagrid.Columns.Count;
for (int i2 = 0; i < cc; i2++)
{
row.Cells[i].Value = yourdatagrid.Rows[0].Cells[i].Value;
}
yourdatagrid.Rows.Add(row);
i++;
}
}
This should work. I'm not sure about how the binding works though. Hopefully it won't prevent this from working.
git remote add origin <remote_repo_url>
git push --all origin
If you want to set all of your branches to automatically use this remote repo when you use git pull
, add --set-upstream
to the push:
git push --all --set-upstream origin
According to SQL2000 help, sp_spaceused includes data and indexes.
This script should do:
CREATE TABLE #t (name SYSNAME, rows CHAR(11), reserved VARCHAR(18),
data VARCHAR(18), index_size VARCHAR(18), unused VARCHAR(18))
EXEC sp_msforeachtable 'INSERT INTO #t EXEC sp_spaceused ''?'''
-- SELECT * FROM #t ORDER BY name
-- SELECT name, CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3)) FROM #t ORDER BY name
SELECT SUM(CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3))) FROM #t
DROP TABLE #t
There's a strong culture of tuples being for heterogeneous collections, similar to what you'd use struct
s for in C, and lists being for homogeneous collections, similar to what you'd use arrays for. But I've never quite squared this with the mutability issue mentioned in the other answers. Mutability has teeth to it (you actually can't change a tuple), while homogeneity is not enforced, and so seems to be a much less interesting distinction.
for (var i in conf) {
val = conf[i];
console.log(val.path);
}
The best way to do it is to use SerializationUtils
from Apache Commons Lang.
To serialize:
byte[] data = SerializationUtils.serialize(yourObject);
To deserialize:
YourObject yourObject = SerializationUtils.deserialize(data)
As mentioned, this requires Commons Lang library. It can be imported using Gradle:
compile 'org.apache.commons:commons-lang3:3.5'
Maven:
<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.5</version>
</dependency>
And more ways mentioned here
Alternatively, the whole collection can be imported. Refer this link
I was getting the below as well trying to get out to github.com as our proxy re-writes the HTTPS connection with their self-signed cert:
no peer certificate available No client certificate CA names sent
In my output there was also:
Protocol : TLSv1.3
I added -tls1_2
and it worked fine and now I can see which CA it is using on the outgoing request. e.g.:
openssl s_client -connect github.com:443 -tls1_2
The selected answer authored by Anurag is only partially correct. Due to some internals of jQuery's event handling, the proposed bindFirst function will not work if you have a mix of handlers with and without filters (ie: $(document).on("click", handler) vs $(document).on("click", "button", handler)).
The issue is that jQuery will place (and expect) that the first elements in the handler array will be these filtered handlers, so placing our event without a filter at the beginning breaks this logic and things start to fall apart. The updated bindFirst function should be as follows:
$.fn.bindFirst = function (name, fn) {
// bind as you normally would
// don't want to miss out on any jQuery magic
this.on(name, fn);
// Thanks to a comment by @Martin, adding support for
// namespaced events too.
this.each(function () {
var handlers = $._data(this, 'events')[name.split('.')[0]];
// take out the handler we just inserted from the end
var handler = handlers.pop();
// get the index of the first handler without a selector
var firstNonDelegate = handlers.first(function(h) { return !h.selector; });
var index = firstNonDelegate ? handlers.indexOf(firstNonDelegate)
: handlers.length; // Either all handlers are selectors or we have no handlers
// move it at the beginning
handlers.splice(index, 0, handler);
});
};

Using "groupby" and list comprehension:
Storing all the split dataframe in list variable and accessing each of the seprated dataframe by their index.
DF = pd.DataFrame({'chr':["chr3","chr3","chr7","chr6","chr1"],'pos':[10,20,30,40,50],})
ans = [pd.DataFrame(y) for x, y in DF.groupby('chr', as_index=False)]
accessing the separated DF like this:
ans[0]
ans[1]
ans[len(ans)-1] # this is the last separated DF
accessing the column value of the separated DF like this:
ansI_chr=ans[i].chr
int
given base 2 and then hex
:
>>> int('010110', 2)
22
>>> hex(int('010110', 2))
'0x16'
>>>
>>> hex(int('0000010010001101', 2))
'0x48d'
The doc of int
:
int(x[, base]) -> integer Convert a string or number to an integer, if possible. A floating
point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If base is zero, the proper base is guessed based on the string content. If the argument is outside the integer range a long object will be returned instead.
The doc of hex
:
hex(number) -> string Return the hexadecimal representation of an integer or long
integer.
To create elements with equal width using Flex
, you should set to your's child (flex elements):
flex-basis: 25%;
flex-grow: 0;
It will give to all elements in row 25% width. They will not grow and go one by one.
curl -s -v -o/dev/null -H "Testheader: test" http://www.example.com
You could also use -I
option if you want to send a HEAD request and not a GET request.
It didn't work for me with all those steps. Strangely enough I noticed Intellisense was working for another solution in visual studio 2015, but not for a specific one.
I located and deleted the .suo file and restarted visual studio. That fixed it for me.
Traditionally, if you only want to change the variable in your terminal windows, set it in .bashrc
file, which is sourced each time a new terminal is opened. .profile
file is not sourced each time you open a new terminal.
See the difference between .profile and .bashrc in question: What's the difference between .bashrc, .bash_profile, and .environment?
.bashrc
should solve your problem. However, it is not the proper solution since you are using Ubuntu. See the relevant Ubuntu help page "Session-wide environment variables". Thus, no wonder that .profile
does not work for you. I use Ubuntu 12.04 and xfce. I set up my .profile
and it is simply not taking effect even if I log out and in. Similar experience here. So you may have to use .pam_environment
file and totally forget about .profile
, and .bashrc
. And NOTE that .pam_environment
is not a script file.
From your situation it sounds like you need to create a "Revision#" folder once a day with a "Reports" folder in there. If that's the case, you just need to know what the next revision number is. Write a function that gets the next revision number, Get-NextRevisionNumber. Or you could do something like this:
foreach($Project in (Get-ChildItem "D:\TopDirec" -Directory)){
# Select all the Revision folders from the project folder.
$Revisions = Get-ChildItem "$($Project.Fullname)\Revision*" -Directory
# The next revision number is just going to be one more than the highest number.
# You need to cast the string in the first pipeline to an int so Sort-Object works.
# If you sort it descending the first number will be the biggest so you select that one.
# Once you have the highest revision number you just add one to it.
$NextRevision = ($Revisions.Name | Foreach-Object {[int]$_.Replace('Revision','')} | Sort-Object -Descending | Select-Object -First 1)+1
# Now in this we kill two birds with one stone.
# It will create the "Reports" folder but it also creates "Revision#" folder too.
New-Item -Path "$($Project.Fullname)\Revision$NextRevision\Reports" -Type Directory
# Move on to the next project folder.
# This untested example loop requires PowerShell version 3.0.
}
Here is, how I've handled this issue (Mac OS X 10.8.4):
1) Because I previously have installed Android Studio the sdk located here: Applications/Android Studio.app/sdk
You can dig into Android Studio.app folder by hitting "Show package contents" in context menu
2) Simply copy the "sdk" folder to another location and write it down to Eclipse preferences. Because I couldn't find how to properly add adress like "/Android Studio.app/sdk" (folder with .app extension) to Eclipse preferences.
I know that this solution is not smooth and best, but it works (at least for me). And I've tried all advices in this theme, and installed the ADT from http://dl-ssl.google.com/android/eclipse/ before, but the error window have kept appearing every time.
For WinRT (Windows Store App)
using Windows.UI;
using Windows.UI.Xaml.Media;
public static Brush ColorToBrush(string color) // color = "#E7E44D"
{
color = color.Replace("#", "");
if (color.Length == 6)
{
return new SolidColorBrush(ColorHelper.FromArgb(255,
byte.Parse(color.Substring(0, 2), System.Globalization.NumberStyles.HexNumber),
byte.Parse(color.Substring(2, 2), System.Globalization.NumberStyles.HexNumber),
byte.Parse(color.Substring(4, 2), System.Globalization.NumberStyles.HexNumber)));

To populate a List of String, you need not use custom row mapper. Implement it using queryForList
.
List<String>data=jdbcTemplate.queryForList(query,String.class)
You can try something like this:
Inside customview constructor:
mContext = context;
Next inside customview you can call:
((MainActivity) mContext).updateText( text );
Inside MainAcivity
define:
public void updateText(final String text) {
TextView txtView = (TextView) findViewById(R.id.text);
txtView.setText(text);
}
It works for me.
If that is the entire line, it very well might be because you are missing a ;
at the end of the line.
I Would suggest the following:
var="any given string"
N=${#var}
G=${var//g/}
G=${#G}
(( G = N - G ))
echo "$G"
No call to any other program
I wrote this extension method based off @Lee's response to the OP. Note, a default parameter was used (requiring C# 4.0). However, an overloaded method call in C# 3.0 would suffice.
/// <summary>
/// Method that returns all the duplicates (distinct) in the collection.
/// </summary>
/// <typeparam name="T">The type of the collection.</typeparam>
/// <param name="source">The source collection to detect for duplicates</param>
/// <param name="distinct">Specify <b>true</b> to only return distinct elements.</param>
/// <returns>A distinct list of duplicates found in the source collection.</returns>
/// <remarks>This is an extension method to IEnumerable<T></remarks>
public static IEnumerable<T> Duplicates<T>
(this IEnumerable<T> source, bool distinct = true)
{
if (source == null)
{
throw new ArgumentNullException("source");
}
// select the elements that are repeated
IEnumerable<T> result = source.GroupBy(a => a).SelectMany(a => a.Skip(1));
// distinct?
if (distinct == true)
{
// deferred execution helps us here
result = result.Distinct();
}
return result;
}
Here is one equivalent of the accepted answer for the UTF-8 world.
if (!preg_match('/^[\p{L}\p{N}_-]+$/u', $string)){
//Disallowed Character In $string
}
Explanation:
Note, that if the hyphen is the last character in the class definition it does not need to be escaped. If the dash appears elsewhere in the class definition it needs to be escaped, as it will be seen as a range character rather then a hyphen.
The first argument should be the path to the executable program. So
gdb progname 12271
Try with this code, you will get the image preview while uploading
<input type='file' id="upload" onChange="readURL(this);"/>
<img id="img" src="#" alt="your image" />
function readURL(input){
var ext = input.files[0]['name'].substring(input.files[0]['name'].lastIndexOf('.') + 1).toLowerCase();
if (input.files && input.files[0] && (ext == "gif" || ext == "png" || ext == "jpeg" || ext == "jpg"))
var reader = new FileReader();
reader.onload = function (e) {
$('#img').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}else{
$('#img').attr('src', '/assets/no_preview.png');
}
}
How do I check if something is (not) in a list in Python?
The cheapest and most readable solution is using the in
operator (or in your specific case, not in
). As mentioned in the documentation,
The operators
in
andnot in
test for membership.x in s
evaluates toTrue
ifx
is a member ofs
, andFalse
otherwise.x not in s
returns the negation ofx in s
.
Additionally,
The operator
not in
is defined to have the inverse true value ofin
.
y not in x
is logically the same as not y in x
.
Here are a few examples:
'a' in [1, 2, 3]
# False
'c' in ['a', 'b', 'c']
# True
'a' not in [1, 2, 3]
# True
'c' not in ['a', 'b', 'c']
# False
This also works with tuples, since tuples are hashable (as a consequence of the fact that they are also immutable):
(1, 2) in [(3, 4), (1, 2)]
# True
If the object on the RHS defines a __contains__()
method, in
will internally call it, as noted in the last paragraph of the Comparisons section of the docs.
...
in
andnot in
, are supported by types that are iterable or implement the__contains__()
method. For example, you could (but shouldn't) do this:
[3, 2, 1].__contains__(1)
# True
in
short-circuits, so if your element is at the start of the list, in
evaluates faster:
lst = list(range(10001))
%timeit 1 in lst
%timeit 10000 in lst # Expected to take longer time.
68.9 ns ± 0.613 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
178 µs ± 5.01 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
If you want to do more than just check whether an item is in a list, there are options:
list.index
can be used to retrieve the index of an item. If that element does not exist, a ValueError
is raised.list.count
can be used if you want to count the occurrences.set
s?Ask yourself these questions:
hash
on them?If you answered "yes" to these questions, you should be using a set
instead. An in
membership test on list
s is O(n) time complexity. This means that python has to do a linear scan of your list, visiting each element and comparing it against the search item. If you're doing this repeatedly, or if the lists are large, this operation will incur an overhead.
set
objects, on the other hand, hash their values for constant time membership check. The check is also done using in
:
1 in {1, 2, 3}
# True
'a' not in {'a', 'b', 'c'}
# False
(1, 2) in {('a', 'c'), (1, 2)}
# True
If you're unfortunate enough that the element you're searching/not searching for is at the end of your list, python will have scanned the list upto the end. This is evident from the timings below:
l = list(range(100001))
s = set(l)
%timeit 100000 in l
%timeit 100000 in s
2.58 ms ± 58.9 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
101 ns ± 9.53 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
As a reminder, this is a suitable option as long as the elements you're storing and looking up are hashable. IOW, they would either have to be immutable types, or objects that implement __hash__
.
default-username = root
password = you-know-it-better
url for localhost = jdbc:mysql://localhost
default-port = 3306
There is a rails plugin called Annotate models, that will generate your model attributes on the top of your model files here is the link:
https://github.com/ctran/annotate_models
to keep the annotation in sync, you can write a task to re-generate annotate models after each deploy.
Accordig to this: https://bugs.mysql.com/bug.php?id=54784 casting as char should do the trick:
SELECT report_id, computer_id, MAX(CAST(date_entered AS CHAR))
FROM reports
GROUP BY report_id, computer_id
For me the best option is to use CSS pseudo elements, so for disc
bullet styling it would look like that:
ul {_x000D_
list-style-type: none;_x000D_
}_x000D_
_x000D_
li {_x000D_
position: relative;_x000D_
}_x000D_
_x000D_
li:before {_x000D_
content: '';_x000D_
display: block;_x000D_
position: absolute;_x000D_
width: 5px; /* adjust to suit your needs */_x000D_
height: 5px; /* adjust to suit your needs */_x000D_
border-radius: 50%;_x000D_
left: -15px; /* adjust to suit your needs */_x000D_
top: 0.5em;_x000D_
background: #f00; /* adjust to suit your needs */_x000D_
}
_x000D_
<ul>_x000D_
<li>first</li>_x000D_
<li>second</li>_x000D_
<li>third</li>_x000D_
</ul>
_x000D_
Notes:
width
and height
should have equal values to keep pointers roundedborder-radius
to zero if you want to have square
list bulletsFor more bullets styles you may use other css shapes https://css-tricks.com/examples/ShapesOfCSS/ (choose this which doesn't require pseudo elements to work, so for example triangles)

Just want to share with what I used so far to save your time.
Here are examples of hard-coded headers and dynamic headers (in case if don't care about data structure). In both cases I wrote some simple directive: customSort
customSort
.directive("customSort", function() {
return {
restrict: 'A',
transclude: true,
scope: {
order: '=',
sort: '='
},
template :
' <a ng-click="sort_by(order)" style="color: #555555;">'+
' <span ng-transclude></span>'+
' <i ng-class="selectedCls(order)"></i>'+
'</a>',
link: function(scope) {
// change sorting order
scope.sort_by = function(newSortingOrder) {
var sort = scope.sort;
if (sort.sortingOrder == newSortingOrder){
sort.reverse = !sort.reverse;
}
sort.sortingOrder = newSortingOrder;
};
scope.selectedCls = function(column) {
if(column == scope.sort.sortingOrder){
return ('icon-chevron-' + ((scope.sort.reverse) ? 'down' : 'up'));
}
else{
return'icon-sort'
}
};
}// end link
}
});
I used single ng-repeat
This is a good example in Fiddle (Notice, there is no jQuery library!)
<tbody>
<tr ng-repeat="item in pagedItems[currentPage] | orderBy:sortingOrder:reverse">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.description}}</td>
<td>{{item.field3}}</td>
<td>{{item.field4}}</td>
<td>{{item.field5}}</td>
</tr>
</tbody>
Demo 2: Fiddle
HTML
<table class="table table-striped table-condensed table-hover">
<thead>
<tr>
<th ng-repeat="header in table_headers"
class="{{header.name}}" custom-sort order="header.name" sort="sort"
>{{ header.name }}
</th>
</tr>
</thead>
<tfoot>
<td colspan="6">
<div class="pagination pull-right">
<ul>
<li ng-class="{disabled: currentPage == 0}">
<a href ng-click="prevPage()">« Prev</a>

<li ng-repeat="n in range(pagedItems.length, currentPage, currentPage + gap) "
ng-class="{active: n == currentPage}"
ng-click="setPage()">
<a href ng-bind="n + 1">1</a>
</li>
<li ng-class="{disabled: (currentPage) == pagedItems.length - 1}">
<a href ng-click="nextPage()">Next »</a>

</ul>
</div>
</td>
</tfoot>
<pre>pagedItems.length: {{pagedItems.length|json}}</pre>
<pre>currentPage: {{currentPage|json}}</pre>
<pre>currentPage: {{sort|json}}</pre>

<tr ng-repeat="item in pagedItems[currentPage] | orderBy:sort.sortingOrder:sort.reverse">
<td ng-repeat="val in item" ng-bind-html-unsafe="item[table_headers[$index].name]"></td>
</tr>
</tbody>
</table>
As a side note:
The ng-bind-html-unsafe
is deprecated, so I used it only for Demo (2nd example). You welcome to edit.

I have tried this for reloading current page.
Try this for Windows:
npm uninstall -g cordova
Try this for MAC:
sudo npm uninstall -g cordova
You can also add Cordova like this:
If You Want To install the previous version of Cordova through the Node Package Manager (npm):
npm install -g [email protected]
If You Want To install the latest version of Cordova:
npm install -g cordova
Enjoy!
A simple rule for us to remember what to use in which case:
In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE
has ANSI_QUOTES
enabled.
(For anybody looking how to do it in Visual Studio!)
Since my comment got a few upvotes, I figured I'd leave it as an answer:
ffmpeg -i 00000.avi -map 0:v:0 -c copy -f null -y /dev/null 2>&1 | grep -Eo 'frame= *[0-9]+ *' | grep -Eo '[0-9]+' | tail -1
This should be fast, since no encoding is being performed. ffmpeg
will just demux the file and read (decode) the first video stream as quickly as possible. The first grep
command will grab the text that shows the frame. The second grep
command will grab just the number from that. The tail
command will just show the final line (final frame count).
you can use this:
try {
Intent followIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href=" +
"https://www.facebook.com/app_scoped_user_id/"+scoped user id+"/"));
activity.startActivity(followIntent);
} catch (Exception e) {
activity.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + user name)));
String errorMessage = (e.getMessage() == null) ? "Message is empty" : e.getMessage();
}
attention: you can get scoped user id from "link" permission facebook api
try ps -n
in a linux terminal. This will show:
1.All processes RUNNING, their command line and their PIDs
Afterwards you will know which process to kill
SELECT Username, date, value
from MyTable mt
inner join (select username, max(date) date
from MyTable
group by username) sub
on sub.username = mt.username
and sub.date = mt.date
Would address the updated problem. It might not work so well on large tables, even with good indexing.

On RHEL Linux just issue:

That is all. After that You will find in the log file next informational message:

All operations will be noticeably faster than before.
For horizontal and vertical alignment of text in graphics,
you might want to use the following CSS styles.
In particular, note that dominant-baseline:middle
is probably wrong,
since this is (usually) half way between the top and the baseline,
rather than half way between the top and the bottom.
Also, some some sources (e.g. Mozilla) use dominant-baseline:hanging
instead of
dominant-baseline:text-before-edge
. This is also probably wrong, since
hanging
is designed for Indic scripts.
Of course, if you're using a mixture of Latin, Indic, ideographs
or whatever, you'll probably need to read the documentation.
/* Horizontal alignment */
text.goesleft{text-anchor:end}
text.equalleftright{text-anchor:middle}
text.goesright{text-anchor:start}
/* Vertical alignment */
text.goesup{dominant-baseline:text-after-edge}
text.equalupdown{dominant-baseline:central}
text.goesdown{dominant-baseline:text-before-edge}
text.ruledpaper{dominant-baseline:alphabetic}
Edit: I've just noticed that Mozilla also uses dominant-baseline:baseline
which is definitely wrong: it's not even a recognized value! I assume it's defaulting to the font default, which is alphabetic
, so they got lucky.
More edit: Safari (11.1.2) understands text-before-edge
but not text-after-edge
. It also fails on ideographic
. Great stuff, Apple. So you might be forced to use alphabetic
and allow for descenders after all. Sorry.

For those who need convert minutes to time with more than 24h format:
DECLARE @minutes int = 7830
SELECT CAST(@minutes / 60 AS VARCHAR(8)) + ':' + FORMAT(@minutes % 60, 'D2') AS [Time]
Result:
130:30
It's a warning, not an error. It occurs because fsevents
is an optional dependency, used only when project is run on macOS environment (the package provides 'Native Access to Mac OS-X FSEvents').
And since you're running your project on Windows, fsevents
is skipped as irrelevant.
There is a PR to fix this behaviour here: https://github.com/npm/cli/pull/169
I came across this issue recently, and i'm using Typescript. If you're using Typescript like I am, then you need to import assets like so:
<img src="@/assets/images/logo.png" alt="">
Try this one:
<body onload="imageRefreshBig();">
Also you might want to check Javascript console for errors (in Chrome it's under Shift + Ctrl + J).
They change how this works so often. This is what I had to do this time (May 2016):
You need to make sure that the previous container you launched is killed, before launching a new one that uses the same port.
docker container ls
docker rm -f <container-name>
You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .
public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
Iterator<String> keys = json.keys();
while(keys.hasNext()){
String key = keys.next();
String val = null;
try{
JSONObject value = json.getJSONObject(key);
parse(value,out);
}catch(Exception e){
val = json.getString(key);
}
if(val != null){
out.put(key,val);
}
}
return out;
}
public static void main(String[] args) throws JSONException {
String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";
JSONObject object = new JSONObject(json);
JSONObject info = object.getJSONObject("ipinfo");
Map<String,String> out = new HashMap<String, String>();
parse(info,out);
String latitude = out.get("latitude");
String longitude = out.get("longitude");
String city = out.get("city");
String state = out.get("state");
String country = out.get("country");
String postal = out.get("postal_code");
System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);
System.out.println("ALL VALUE " + out);
}
Output:
Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}
This should work:
start "" "c:\program files\php\php.exe" D:\mydocs\mp\index.php param1 param2
The start
command interprets the first argument as a window title if it contains spaces. In this case, that means start
considers your whole argument a title and sees no command. Passing ""
(an empty title) as the first argument to start
fixes the problem.
I realize that this answer doesn't really answer your question, but I think it's helpful anyway. Here's an alternative way to implementing the caesar cipher with string methods:
def caesar(plaintext, shift):
alphabet = string.ascii_lowercase
shifted_alphabet = alphabet[shift:] + alphabet[:shift]
table = string.maketrans(alphabet, shifted_alphabet)
return plaintext.translate(table)
In fact, since string methods are implemented in C, we will see an increase in performance with this version. This is what I would consider the 'pythonic' way of doing this.
If you want to take a copy of a live database, do the Backup/Restore method.
[In SQLS2000, not sure about 2008:] Just keep in mind that if you are using SQL Server accounts in this database, as opposed to Windows accounts, if the master DB is different or out of sync on the development server, the user accounts will not translate when you do the restore. I've heard about an SP to remap them, but I can't remember which one it was.
The script to autoincrement the build number in the answer above didn't work for me if the build number is a floating point value, so I modified it a little:
#!/bin/bash
buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=`echo $buildNumber +1|bc`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"
It is difficult to choose which one is better; lock or ReaderWriterLockSlim. You need real world statistics of read and write numbers and ratios etc.
But if you believe using "lock" is the correct way. Then here is a different solution for different needs. I also include the Allan Xu's solution in the code. Because both can be needed for different needs.

JSON is not really meant for serializing arbitrary Python objects. It's great for serializing dict
objects, but the pickle
module is really what you should be using in general. Output from pickle
is not really human-readable, but it should unpickle just fine. If you insist on using JSON, you could check out the jsonpickle
module, which is an interesting hybrid approach.
Hint text not bold, I try to below code.

In 2018 and modern browsers you can send a custom event from iframe to parent window.
iframe:
var data = { foo: 'bar' }
var event = new CustomEvent('myCustomEvent', { detail: data })
window.parent.document.dispatchEvent(event)
parent:
window.document.addEventListener('myCustomEvent', handleEvent, false)
function handleEvent(e) {
console.log(e.detail) // outputs: {foo: 'bar'}
}
PS: Of course, you can send events in opposite direction same way.
document.querySelector('#iframe_id').contentDocument.dispatchEvent(event)
A prettier version of response by @user394430
class Element:
def __init__(self, name, symbol, number):
self.name = name
self.symbol = symbol
self.number = number
def __str__(self):
return str(self.__class__) + '\n'+ '\n'.join(('{} = {}'.format(item, self.__dict__[item]) for item in self.__dict__))
elem = Element('my_name', 'some_symbol', 3)
print(elem)
Produces visually nice list of the names and values.
<class '__main__.Element'>
name = my_name
symbol = some_symbol
number = 3
An even fancier version (thanks Ruud) sorts the items:
def __str__(self):
return str(self.__class__) + '\n' + '\n'.join((str(item) + ' = ' + str(self.__dict__[item]) for item in sorted(self.__dict__)))
You need Ajax to make it happen. Something like this:
$(document).ready(function(){
$("#myform").on('submit', function(){
var name = $("#name").val();
var email = $("#email").val();
var password = $("#password").val();
var contact = $("#contact").val();
var dataString = 'name1=' + name + '&email1=' + email + '&password1=' + password + '&contact1=' + contact;
if(name=='' || email=='' || password=='' || contact=='')
{

You can quickly serve static content in JAVA Spring-boot App via thymeleaf
(ref: source)
I assume you have already added Spring Boot plugin apply plugin: 'org.springframework.boot'
and the necessary buildscript
Then go ahead and ADD thymeleaf to your build.gradle
==>
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
testCompile('org.springframework.boot:spring-boot-starter-test')
}
Lets assume you have added home.html at src/main/resources
To serve this file, you will need to create a controller.
package com.ajinkya.th.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomePageController {
@RequestMapping("/")
public String homePage() {
return "home";
}
}
Thats it ! Now restart your gradle server. ./gradlew bootRun
With PowerShell but without the need to create a script:
Invoke-WebRequest https://dist.nuget.org/win-x86-commandline/latest/nuget.exe -OutFile Nuget.exe
I discovered that there is a second portion of the answer to this.
The first portion helped me, but I still had a space to the right of my type=number
input. I had zeroed out the margin on the input, but apparently I had to zero out the margin on the spinner as well.
This fixed it:
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}
To update this for Python-3 you can do this
"{} {}".format(True, False)
However if you want to actually format the string (e.g. add white space), you encounter Python casting the boolean into the underlying C value (i.e. an int), e.g.
>>> "{:<8} {}".format(True, False)
'1 False'
To get around this you can cast True
as a string, e.g.
>>> "{:<8} {}".format(str(True), False)
'True False'
The way is correct, but can be improved a bit with the extended set-syntax.
set "var=xyz"
Sets the var to the content until the last quotation mark, this ensures that no "hidden" spaces are appended.
Your code would look like
set "var1=A"
set "var2=B"
set "AB=hi"
set "newvar=%var1%%var2%"
echo %newvar% is the concat of var1 and var2
echo !%newvar%! is the indirect content of newvar
The first time I realized that the Unit testing project referenced the app.config in that project rather then the app.config associated with my production code project (off course, DOH) I just added a line in the Post Build Event of the Prod project that will copy the app.config to the bin folder of the test project.
Problem solved
I haven't noticed any weird side effects so far, but I am not sure that this is the right solution, but at least it seems to work.
I was gone through same problem & I resolved it by following steps.
import subprocess
subprocess.call(['D:\greensoft\TTPlayer\TTPlayer.exe', "E:\stridevampaclip.mp3"])
In Python3 You Can use this loop
with open('your_file.txt', 'w') as f:
for item in list:
f.print("", item)
I have created a horizontal ListView in every row of ListView if you want single You can do the following
Here I am just creating horizontalListView of Thumbnail of Videos Like this
The idea is just continuously add the ImageView to the child of LinearLayout in HorizontalscrollView
Note: remember to fire .removeAllViews(); before next time load other wise it will add duplicate child
Cursor mImageCursor = db.getPlaylistVideoImage(playlistId);
mVideosThumbs.removeAllViews();
if (mImageCursor != null && mImageCursor.getCount() > 0) {
for (int index = 0; index < mImageCursor.getCount(); index++) {
mImageCursor.moveToPosition(index);
ImageView iv = (ImageView) imageViewInfalter.inflate(
R.layout.image_view, null);
name = mImageCursor.getString(mImageCursor
.getColumnIndex("LogoDefaultName"));
logoFile = new File(MyApplication.LOCAL_LOGO_PATH, name);
if (logoFile.exists()) {
Uri uri = Uri.fromFile(logoFile);
iv.setImageURI(uri);
}
iv.setScaleType(ScaleType.FIT_XY);
mVideosThumbs.addView(iv);
}
mImageCursor.close();
mImageCursor = null;
} else {
ImageView iv = (ImageView) imageViewInfalter.inflate(
R.layout.image_view, null);
String name = "";
File logoFile;
name = mImageCursor.getString(mImageCursor
.getColumnIndex("LogoMediumName"));
logoFile = new File(MyApplication.LOCAL_LOGO_PATH, name);
if (logoFile.exists()) {
Uri uri = Uri.fromFile(logoFile);
iv.setImageURI(uri);
}
}

Lazy loading images by attaching listener to scroll events or by making use of setInterval is highly non-performant as each call to getBoundingClientRect() forces the browser to re-layout the entire page and will introduce considerable jank to your website.
Use Lozad.js (just 569 bytes with no dependencies), which uses IntersectionObserver to lazy load images performantly.
I would have a directory somewhere called scripts under the WWW folder so that it's not reachable from the web but is reachable by PHP.
e.g. /var/www/scripts/testscript
Make sure the user/group for your testscript
is the same as your webfiles. For instance if your client.php
is owned by apache:apache
, change the bash script to the same user/group using chown
. You can find out what your client.php
and web files are owned by doing ls -al
.
Then run
<?php
$message=shell_exec("/var/www/scripts/testscript 2>&1");
print_r($message);
?>

If you really want to run a file as root from a webserver you can try this binary wrapper below. Check out this solution for the same thing you want to do.
The W3C has a good introduction.

exit
is a helper for the interactive shell - sys.exit
is intended for use in programs.
The
site
module (which is imported automatically during startup, except if the-S
command-line option is given) adds several constants to the built-in namespace (e.g.exit
). They are useful for the interactive interpreter shell and should not be used in programs.
Technically, they do mostly the same: raising SystemExit
. sys.exit
does so in sysmodule.c:
static PyObject *
sys_exit(PyObject *self, PyObject *args)
{
PyObject *exit_code = 0;
if (!PyArg_UnpackTuple(args, "exit", 0, 1, &exit_code))
return NULL;
/* Raise SystemExit so callers may catch it or clean up. */
PyErr_SetObject(PyExc_SystemExit, exit_code);
return NULL;
}
While exit
is defined in site.py and _sitebuiltins.py, respectively.
class Quitter(object):
def __init__(self, name):
self.name = name
def __repr__(self):
return 'Use %s() or %s to exit' % (self.name, eof)
def __call__(self, code=None):
# Shells like IDLE catch the SystemExit, but listen when their
# stdin wrapper is closed.
try:
sys.stdin.close()
except:
pass
raise SystemExit(code)
__builtin__.quit = Quitter('quit')
__builtin__.exit = Quitter('exit')
Note that there is a third exit option, namely os._exit, which exits without calling cleanup handlers, flushing stdio buffers, etc. (and which should normally only be used in the child process after a fork()
).
$sql = "SELECT * FROM MY_TABLE";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!! Check summary get row on array ..
echo "<tr>";
foreach ($row as $field => $value) { // I you want you can right this line like this: foreach($row as $value) {
echo "<td>" . $value . "</td>"; // I just did not use "htmlspecialchars()" function.
}
echo "</tr>";
}
echo "</table>";
I had the same problem. But What I did is I imported the .java files and then I went to Search->File-> and then changed the package name to whatever package it should belong in this way I fixed a lot of java files which otherwise would require to go to every file and change them manually.
Here is the documentation on IEnumerator
. They are used to get the values of lists, where the length is not necessarily known ahead of time (even though it could be). The word comes from enumerate
, which means "to count off or name one by one".
IEnumerator
and IEnumerator<T>
is provided by all IEnumerable
and IEnumerable<T>
interfaces (the latter providing both) in .NET via GetEnumerator()
. This is important because the foreach
statement is designed to work directly with enumerators through those interface methods.
So for example:
IEnumerator enumerator = enumerable.GetEnumerator();
while (enumerator.MoveNext())
{
object item = enumerator.Current;
// Perform logic on the item
}
Becomes:
foreach(object item in enumerable)
{
// Perform logic on the item
}
As to your specific scenario, almost all collections in .NET implement IEnumerable
. Because of that, you can do the following:
public IEnumerator Enumerate(IEnumerable enumerable)
{
// List implements IEnumerable, but could be any collection.
List<string> list = new List<string>();
foreach(string value in enumerable)
{
list.Add(value + "roxxors");
}
return list.GetEnumerator();
}
This will append all the functions that are defined in your_module in a list.
result=[]
for i in dir(your_module):
if type(getattr(your_module, i)).__name__ == "function":
result.append(getattr(your_module, i))
The problem is your angular material version, I have the same, and I have resolved this when I have installed the good version of angular material in local.
Hope it solve yours too.
Your second question
How many columns can be used together as a primary key in a given table?
is implementation specific: it's defined in the actual DBMS being used.[1],[2],[3] You have to inspect the technical specification of the database system you use. Some are very detailed, some are not. Searching the web about such limitations can be hard because the terminology varies. The term composite primary key should be mandatory ;)
If you cannot find explicit information, try creating a test database to ensure you can expect stable (and specific) handling of the limit violations (which are to be expected). Be careful to get the right information about this: sometimes the limits are accumulated, and you'll see different results with different database layouts.
Try passing width=200
as additional paramater when creating the Label.
This should work in creating label with specified width.
If you want to change it later, you can use:
label.config(width=200)
As you want to change the size of font itself you can try:
label.config(font=("Courier", 44))
Just call moment as a function without any arguments:
moment()
For timezone information with moment, look at the moment-timezone
package: http://momentjs.com/timezone/
In windows you should use %WORKSPACE%
.
Check out perlfaq4: How do I merge two hashes. There is a lot of good information already in the Perl documentation and you can have it right away rather than waiting for someone else to answer it. :)
Before you decide to merge two hashes, you have to decide what to do if both hashes contain keys that are the same and if you want to leave the original hashes as they were.
If you want to preserve the original hashes, copy one hash (%hash1) to a new hash (%new_hash), then add the keys from the other hash (%hash2 to the new hash. Checking that the key already exists in %new_hash gives you a chance to decide what to do with the duplicates:
my %new_hash = %hash1; # make a copy; leave %hash1 alone
foreach my $key2 ( keys %hash2 )
{
if( exists $new_hash{$key2} )
{
warn "Key [$key2] is in both hashes!";
# handle the duplicate (perhaps only warning)
...
next;
}
else
{
$new_hash{$key2} = $hash2{$key2};
}
}
If you don't want to create a new hash, you can still use this looping technique; just change the %new_hash to %hash1.
foreach my $key2 ( keys %hash2 )
{
if( exists $hash1{$key2} )
{
warn "Key [$key2] is in both hashes!";
# handle the duplicate (perhaps only warning)
...
next;
}
else
{
$hash1{$key2} = $hash2{$key2};
}
}
If you don't care that one hash overwrites keys and values from the other, you could just use a hash slice to add one hash to another. In this case, values from %hash2 replace values from %hash1 when they have keys in common:
@hash1{ keys %hash2 } = values %hash2;
If you want to pull a particular file from another branch just do
git checkout branch1 -- filenamefoo.txt
This will pull a version of the file from one branch into the current tree
In MySQL, certain words like SELECT
, INSERT
, DELETE
etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.
As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):
Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.
...
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.
...
The identifier quote character is the backtick ("
`
"):
A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.
You have two options.
The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.
Doing this has a couple of advantages:
It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.
The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.
Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.
If renaming the table or column isn't possible, wrap the offending identifier in backticks (`
) as described in the earlier quote from 10.2 Schema Object Names.
An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):
mysql> CREATE TABLE interval (begin INT, end INT); ERROR 1064 (42000): You have an error in your SQL syntax. near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT); Query OK, 0 rows affected (0.01 sec)
Similarly, the query from the question can be fixed by wrapping the keyword key
in backticks, as shown below:
INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)"; ^ ^
XML Schemas describe hierarchial data models and may not map well to a relational data model. Mapping XSD's to database tables is very similar mapping objects to database tables, in fact you could use a framework like Castor that does both, it allows you to take a XML schema and generate classes, database tables, and data access code. I suppose there are now many tools that do the same thing, but there will be a learning curve and the default mappings will most like not be what you want, so you have to spend time customizing whatever tool you use.
XSLT might be the fastest way to generate exactly the code that you want. If it is a small schema hardcoding it might be faster than evaluating and learing a bunch of new technologies.
I believe that there is an issue with git for Windows where git randomly writes the wrong line endings on checkout and the only workaround is to checkout some other branch and force git to ignore changes. Then checkout the branch you actually want to work on.
git checkout master -f
git checkout <your branch>
Be aware that this will discard any changes you might have intentionally made, so only do this if you have this problem immediately after checkout.
Edit: I might have actually got lucky the first time. It turns out that I got bit again after switching branches. It turned out that the files git was reporting as modified after changing branches was changing. (Apparently because git was not consistently applying the CRLF line ending to files properly.)
I updated to the latest git for Windows and hope the problem is gone.
When you use the keyword new
for example JFrame j = new JFrame();
you are creating an instance of the class JFrame
.
The
new
operator instantiates a class by allocating memory for a new object and returning a reference to that memory.
Note: The phrase "instantiating a class" means the same thing as "creating an object." When you create an object, you are creating an "instance" of a class, therefore "instantiating" a class.
Take a look here
Creating Objects
The types of the Java programming language are divided into two categories:
primitive types
andreference
types.
Thereference
types areclass
types,interface
types, andarray
types.
There is also a specialnull
type.
An object is a dynamically created instance of aclass
type or a dynamically createdarray
.
The values of areference
type are references to objects.
Refer Types, Values, and Variables for more information
You need to put an actual tab character after the -t\ and to do that in a shell you hit ctrl-v and then the tab character. Most shells I've used support this mode of literal tab entry.
Beware, though, because copying and pasting from another place generally does not preserve tabs.
Tried and tested. I know that this works:
Replace(EmailText, vbNewLine, "<br>")
i.e. vbNewLine
is also the equivalent of \n
The real reason you were getting this error is because of the "
values in your connection string.
If you replace those with single quotes then it will work fine.
https://docs.microsoft.com/archive/blogs/rickandy/explicit-connection-string-for-ef
(Posted so others can get the fix faster than I did.)
I think this could be done in a much simpler way:
So code would look something like this:
WebElement month = driver.findElement(month combo locator);
Select monthCombo = new Select(month);
monthCombo.selectByVisibleText("March");
WebElement year = driver.findElement(year combo locator);
Select yearCombo = new Select(year);
yearCombo.selectByVisibleText("2015");
driver.click(By.linkText("31"));
This won't work if the date picker dropdowns are not Select, but most of the ones I've seen are individual elements (select, links, etc.)
I used Atom, to open files this works for me
atom index.html
Hopefully this helps.

Note that this isn't perfect, since if you had something like, say, <a title=">">
it would break. However, it's about the closest you'd get in non-library Python without a really complex function:
import re
TAG_RE = re.compile(r'<[^>]+>')
def remove_tags(text):
return TAG_RE.sub('', text)
However, as lvc mentions xml.etree
is available in the Python Standard Library, so you could probably just adapt it to serve like your existing lxml
version:
def remove_tags(text):
return ''.join(xml.etree.ElementTree.fromstring(text).itertext())
A modern approach using STRING_SPLIT, requires SQL Server 2016 and above.
DECLARE @string varchar(100) = 'Hello John Smith'
SELECT

Result:

3 Smith
Now it is possible to get th nth element from the row number.

First lets take a look at how can we define a variable in mysql
To define a varible in mysql it should start with '@' like @{variable_name} and this '{variable_name}', we can replace it with our variable name.
Now, how to assign a value in a variable in mysql. For this we have many ways to do that
Example :-
mysql > SET @a = 1;
Example:-
mysql > @a:=1;
Example:-
mysql > select 1 into @a;
Here @a is user defined variable and 1 is going to be assigned in @a.
Now how to get or select the value of @{variable_name}.
we can use select statement like
Example :-
mysql > select @a;
it will show the output and show the value of @a.
Now how to assign a value from a table in a variable.
For this we can use two statement like :-
1.
@a := (select emp_name from employee where emp_id = 1);
select emp_name into @a from employee where emp_id = 1;
Always be careful emp_name must return single value otherwise it will throw you a error in this type statements.
refer this:- http://www.easysolutionweb.com/sql-pl-sql/how-to-assign-a-value-in-a-variable-in-mysql
I was getting this error on Vue 3. It was because defineComponent

created() {
this.testF();
},
methods: {
testF() {
console.log("testF");
},
},
});

With the ConstraintLayout v1.1.2, the dimension should be set to 0dp
and then set the layout_constraintWidth_percent
or layout_constraintHeight_percent
attributes to a value between 0 and 1 like :
<!-- 50% width centered Button -->
<Button
android:id="@+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintWidth_percent=".5" />
(You don't need to set app:layout_constraintWidth_default="percent"
or app:layout_constraintHeight_default="percent"
with ConstraintLayout 1.1.2 and following versions)
__del__()
gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.__init__()
raises an exception then the object is assumed to be incomplete and __del__()
won't be invoked.You can use the datapart to maintain time date type and you can compare it to another time.
Check below example:
declare @fromtime time = '09:30'
declare @totime time
SET @totime=CONVERT(TIME, CONCAT(DATEPART(HOUR, GETDATE()),':', DATEPART(MINUTE, GETDATE())))
if @fromtime <= @totime
begin print 'true' end
else begin print 'no' end
If you want to allow client-side manipulation of persistent data, then it's best to just use cookies. That's what cookies were designed for.
My situation and solution: I had created and enabled a HyperV ethernet adapter. For some reason, my main windows machine was using the "virtual" ethernet adapter instead of the 'hardware' adapter.
I disabled the virtual ethernet and my network settings to change the network public/privacy settings were revealed.
I've always known it as kebab-case
.
On a funny note, I've heard people call it a SCREAM-KEBAB
when all the letters are capitalized.
I've always liked kebab-case
as it seems the most readable when you need whitespace. However, some programs interpret the dash as a minus sign, and it can cause problems as what you think is a name turns into a subtraction operation.
first-second // first minus second?
ten-2 // ten minus two?
Also, some frameworks parse dashes in kebab cased property. For example, GitHub Pages uses Jekyll, and Jekyll parses any dashes it finds in an md file. For example, a file named 2020-1-2-homepage.md
on GitHub Pages gets put into a folder structured as \2020\1\2\homepage.html
when the site is compiled.
A safer alternative to kebab-case
is snake_case
, or SCREAMING_SNAKE_CAS
E, as underscores cause less confusion when compared to a minus sign.
The package nail
provides an enhanced mailx like interface. It includes the -r
option.
On Centos 5 installing the package mailx
gives you a program called mail
, which doesn't support the mailx
options.
If you have an issue where you only want to remove trailing characters, you can try this:

This solved a problem I had with addresses where a procedure created a field with a fixed number of lines, even if those lines were empty. To save space in my SSRS report, I cut them down.
I would combine node-http-proxy and express.
node-http-proxy will support a proxy inside your node.js web server via RoutingProxy
(see the example called Proxy requests within another http server).
Inside your custom server logic you can do authentication using express. See the auth sample here for an example.
Combining those two examples should give you what you want.
You could just do it manually.
NB: might be better to use a HashMap instead of an inner class for the opts.
/** convenient "-flag opt" combination */
private class Option {
String flag, opt;
public Option(String flag, String opt) { this.flag = flag; this.opt = opt; }
}
static public void main(String[] args) {
List<String> argsList = new ArrayList<String>();
List<Option> optsList = new ArrayList<Option>();
List<String> doubleOptsList = new ArrayList<String>();
for (int i = 0; i < args.length; i++) {
switch (args[i].charAt(0)) {
case '-':
if (args[i].length < 2)
throw new IllegalArgumentException("Not a valid argument: "+args[i]);
if (args[i].charAt(1) == '-') {
if (args[i].length < 3)
throw new IllegalArgumentException("Not a valid argument: "+args[i]);
// --opt
doubleOptsList.add(args[i].substring(2, args[i].length));
} else {
if (args.length-1 == i)
throw new IllegalArgumentException("Expected arg after: "+args[i]);
// -opt
optsList.add(new Option(args[i], args[i+1]));
i++;
}
break;
default:
// arg
argsList.add(args[i]);
break;
}
}
// etc
}

you can put your json in a parameter and send it instead of put only your json in header:
$post_string= 'json_param=' . json_encode($data);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $post_string);
curl_setopt($curl, CURLOPT_URL, 'http://webservice.local/'); // Set the url path we want to call
//execute post
$result = curl_exec($curl);
//see the results
$json=json_decode($result,true);
curl_close($curl);
print_r($json);
on the service side you can get your json string as a parameter:
$json_string = $_POST['json_param'];
$obj = json_decode($json_string);
then you can use your converted data as object.
Partial mocking using Mockito's spy method could be the solution to your problem, as already stated in the answers above. To some degree I agree that, for your concrete use case, it may be more appropriate to mock the DB lookup. From my experience this is not always possible - at least not without other workarounds - that I would consider as being very cumbersome or at least fragile. Note, that partial mocking does not work with ally versions of Mockito. You have use at least 1.8.0.
I would have just written a simple comment for the original question instead of posting this answer, but StackOverflow does not allow this.
Just one more thing: I really cannot understand that many times a question is being asked here gets comment with "Why you want to do this" without at least trying to understand the problem. Escpecially when it comes to then need for partial mocking there are really a lot of use cases that I could imagine where it would be useful. That's why the guys from Mockito provided that functionality. This feature should of course not be overused. But when we talk about test case setups that otherwise could not be established in a very complicated way, spying should be used.
You can't treat a PDF like an HTML document. Images can't "float" within a document and have things flow around them, or flow with surrounding text. FPDF allows you to embed html in a text block, but only because it parses the tags and replaces <i>
and <b>
and so on with Postscript equivalent commands. It's not smart enough to dynamically place an image.
In other words, you have to specify coordinates (and if you don't, the current location's coordinates will be used anyways).
To insert a single row of data:
INSERT INTO USERS
VALUES (1, 'Mike', 'Jones');
To do an insert on specific columns (as opposed to all of them) you must specify the columns you want to update.
INSERT INTO USERS (FIRST_NAME, LAST_NAME)
VALUES ('Stephen', 'Jiang');
To insert multiple rows of data in SQL Server 2008 or later:
INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe'),
(3, 'Linda', 'Mitchell'),
(4, 'Jillian', 'Carson'),
(5, 'Garrett', 'Vargas');
To insert multiple rows of data in earlier versions of SQL Server, use "UNION ALL" like so:
INSERT INTO USERS (FIRST_NAME, LAST_NAME)
SELECT 'James', 'Bond' UNION ALL
SELECT 'Miss', 'Moneypenny' UNION ALL
SELECT 'Raoul', 'Silva'
Note, the "INTO" keyword is optional in INSERT queries. Source and more advanced querying can be found here.
SELECT IDENT_CURRENT('Table')
You can use one of these examples:
SELECT * FROM Table
WHERE ID = (
SELECT IDENT_CURRENT('Table'))
SELECT * FROM Table
WHERE ID = (
SELECT MAX(ID) FROM Table)
SELECT TOP 1 * FROM Table
ORDER BY ID DESC
But the first one will be more efficient because no index scan is needed (if you have index on Id column).
The second one solution is equivalent to the third (both of them need to scan table to get max id).
Notepad++ only has column editing. This is not completely the same as multiple cursors.
Sublime Text has a marvelous implementation of this, might be worth checking out...
It's a relatively new editor (2011) that is gaining popularity quite fast:
http://www.google.com/trends/explore#q=Notepad%2B%2B%2C%20Sublime%20Text&cmpt=q
Edit: Apparently somewhere around Notepad++ version 6.x multi-cursor editing got added, but there are still a few more advanced features for it in Sublime, like "select next occurrence".
I am not sure if this is efficient, but this is one of the possible ways:
Read json from url use url.openStream()
and read contents into a string.
construct a JSON object with this string (more at json.org)
JSONObject(java.lang.String source)
Construct a JSONObject from a source JSON text string.
The other answer describing arrays of arrays are correct.
BUT if you are planning of doing a anything mathematical with the arrays - or need something special like sparse matrices you should look at one of the many maths libs like TNT before re-inventing too many wheels
def aliasAllColumns(t: DataFrame, p: String = "", s: String = ""): DataFrame =
{
t.select( t.columns.map { c => t.col(c).as( p + c + s) } : _* )
}
In case is isn't obvious, this adds a prefix and a suffix to each of the current column names. This can be useful when you have two tables with one or more columns having the same name, and you wish to join them but still be able to disambiguate the columns in the resultant table. It sure would be nice if there were a similar way to do this in "normal" SQL.
The snippet you're showing doesn't seem to be directly responsible for the error.
This is how you can CAUSE the error:
namespace MyNameSpace
{
int i; <-- THIS NEEDS TO BE INSIDE THE CLASS
class MyClass
{
...
}
}
If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }
.
Performance wise String concatenation using '+' is costlier because it has to make a whole new copy of String since Strings are immutable in java. This plays particular role if concatenation is very frequent, eg: inside a loop. Following is what my IDEA suggests when I attempt to do such a thing:
General Rules:
Here is a nice Jon Skeet blog around this topic.
In my case I just close the app form emulator
Then run this again
react-native run-android
Jar is an archive, you can replace a file in it by yourself in your favourite file manager (Total Commander for example).
You should change the
<a href="#">My Link</a>
to
<a href="javascript:;">My Link</a>
This way when the link is clicked the page won't scroll to top. This is cleaner than using href="#" and then preventing the default event from running.
I have good reasons for this on the first answer to this question, like the return false;
will not execute if the called function throws an error, or you may add the return false;
to a doSomething()
function and then forget to use return doSomething();
Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.
In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:
CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
one int;
two int;
BEGIN
one := 1;
two := 2;
RETURN one + two;
END
$$;
SELECT somefuncname();
The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.
>>> l = range(1,10)
>>> l
[1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> l[:2]
[1, 2]
>>> l[3:]
[4, 5, 6, 7, 8, 9]
>>> l[:2] + l[3:]
[1, 2, 4, 5, 6, 7, 8, 9]
>>>

Try using the InStr function which returns the index in the string at which the character was found. If InStr returns 0, the string was not found.
If InStr(myString, "A") > 0 Then
For the error on the line assigning to newStr, convert oldStr.IndexOf to that InStr function also.
Left(oldStr, InStr(oldStr, "A"))
Try CSS:
<h2 style="color:#069">Process Report</h2>
If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:
<style type="text/css">

color:#069;
}
</style>
I made this code snippet to reflectively instantiate a class which is passed for a simple automated test utility.
Object attributeValue = null;
try {
if(clazz.isArray()){
Class<?> arrayType = clazz.getComponentType();
attributeValue = Array.newInstance(arrayType, 0);
}
else if(!clazz.isInterface()){
attributeValue = BeanUtils.instantiateClass(clazz);
}
} catch (Exception e) {
logger.debug("Cannot instanciate \"{}\"", new Object[]{clazz});
}
Note this segment:
if(clazz.isArray()){
Class<?> arrayType = clazz.getComponentType();
attributeValue = Array.newInstance(arrayType, 0);
}
for array initiating where Array.newInstance(class of array, size of array). Class can be both primitive (int.class) and object (Integer.class).
BeanUtils is part of Spring.
One can also do this :
<xsl:text disable-output-escaping="yes"><![CDATA[ ]]></xsl:text>
I have been using blockUI to avoid browser incompatibilies on disabled or hidden buttons.
http://malsup.com/jquery/block/#element
Then my buttons have a class autobutton:
$(".autobutton").click(
function(event) {
var nv = $(this).html();
var nv2 = '<span class="fa fa-circle-o-notch fa-spin" aria-hidden="true"></span> ' + nv;
$(this).html(nv2);
var form = $(this).parents('form:first');
$(this).block({ message: null });
form.submit();
});
Then a form is like that:
<form>
....
<button class="autobutton">Submit</button>
</form>
Quotes:
"url: http://www.example-site.com/"
To clarify, I meant “quote the value” and originally thought the entire thing was the value. If http://www.example-site.com/
is the value, just quote it like so:
url: "http://www.example-site.com/"
Why do you need to state both 'x' and 'y' before the ':'?
Because a lambda is (conceptually) the same as a function, just written inline. Your example is equivalent to
def f(x, y) : return x + y
just without binding it to a name like f
.
Also how do you make it return multiple arguments?
The same way like with a function. Preferably, you return a tuple:
lambda x, y: (x+y, x-y)
Or a list, or a class, or whatever.
The thing with self.entry_1.bind
should be answered by Demosthenex.
the above code for chrome is working fine. i have tried like this in mozila but its not working. i found the solution for that
For mozila
input[type=number] {
-moz-appearance: textfield;
appearance: textfield;
margin: 0;
}

Above solution works best if multiple matching sub documents are required. $elemMatch also comes in very use if single matching sub document is required as output
db.test.find({list: {$elemMatch: {a: 1}}}, {'list.$': 1})
Result:
{
"_id": ObjectId("..."),
"list": [{a: 1}]
}

/var/www/html
is just the default root folder of the web server. You can change that to be whatever folder you want by editing your apache.conf
file (usually located in /etc/apache/conf
) and changing the DocumentRoot
attribute (see http://httpd.apache.org/docs/current/mod/core.html#documentroot for info on that)
Many hosts don't let you change these things yourself, so your mileage may vary. Some let you change them, but only with the built in admin tools (cPanel, for example) instead of via a command line or editing the raw config files.
