Use usort:
usort($array, function($a1, $a2) {
$v1 = strtotime($a1['date']);
$v2 = strtotime($a2['date']);
return $v1 - $v2; // $v2 - $v1 to reverse direction
});
I very recently had the some problem and just figured out how to do this. Assuming you have three classes, Primary, B, C and that B,C have a foreign key to primary
class PrimaryForm(ModelForm):
class Meta:
model = Primary
class BForm(ModelForm):
class Meta:
model = B
exclude = ('primary',)
class CForm(ModelForm):
class Meta:
model = C
exclude = ('primary',)
def generateView(request):
if request.method == 'POST': # If the form has been submitted...
primary_form = PrimaryForm(request.POST, prefix = "primary")
b_form = BForm(request.POST, prefix = "b")
c_form = CForm(request.POST, prefix = "c")
if primary_form.is_valid() and b_form.is_valid() and c_form.is_valid(): # All validation rules pass
print "all validation passed"
primary = primary_form.save()
b_form.cleaned_data["primary"] = primary
b = b_form.save()
c_form.cleaned_data["primary"] = primary
c = c_form.save()
return HttpResponseRedirect("/viewer/%s/" % (primary.name))
else:
print "failed"
else:
primary_form = PrimaryForm(prefix = "primary")
b_form = BForm(prefix = "b")
c_form = Form(prefix = "c")
return render_to_response('multi_model.html', {
'primary_form': primary_form,
'b_form': b_form,
'c_form': c_form,
})
This method should allow you to do whatever validation you require, as well as generating all three objects on the same page. I have also used javascript and hidden fields to allow the generation of multiple B,C objects on the same page.
No need to be that hardcore.
Try this :
YourButtonObject.setBackground(0xff99cc00);
If you want to bind an event like 'click' for all the elements having same class in the rendered DOM element then you can set up an event listener by using following parts of the code in components.ts file.
import { Component, OnInit, Renderer, ElementRef} from '@angular/core';
constructor( elementRef: ElementRef, renderer: Renderer) {
dragulaService.drop.subscribe((value) => {
this.onDrop(value.slice(1));
});
}
public onDrop(args) {
let [e, el] = args;
this.toggleClassComTitle(e,'checked');
}
public toggleClassComTitle(el: any, name: string) {
el.querySelectorAll('.com-item-title-anchor').forEach( function ( item ) {
item.addEventListener('click', function(event) {
console.log("item-clicked");
});
});
}
This worked perfectly with grouped calls: Implement a custom subclass of UITableViewCell
This will respect corners and such...
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
if(selected)
[self setBackgroundColor:[UIColor colorWithRed:(245/255.0) green:(255/255.0) blue:(255/255.0) alpha:1]];
else
[self setBackgroundColor:[UIColor whiteColor]];
}
<div style="position:relative; top:-45px;">
<a name="fragment"> </a>
</div>
This code should do the trick. Swap out 45px for the height of your header bar.
EDIT: If using jQuery is an option, I've also been successful using jQuery.localScroll with an offset value set. The offset option is a part of jQuery.scrollTo, which jQuery.localScroll is built upon. A demo is available here: http://demos.flesler.com/jquery/scrollTo/ (second window, under 'offset')
For me on windows it was Ctrl+¡
, indent line. It adds a tab at the beggining of each line.

Thanks to @bmjohn's answer above. Here is a working Xamarin / C# version of the that answer's code, to save others the time of transcription:
AppDelegate.cs
public UIInterfaceOrientationMask OrientationLock = UIInterfaceOrientationMask.All;
public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations(UIApplication application, UIWindow forWindow)
{
return this.OrientationLock;
}
Static OrientationUtility.cs class:
public static class OrientationUtility
{
public static void LockOrientation(UIInterfaceOrientationMask orientation)
{
var appdelegate = (AppDelegate) UIApplication.SharedApplication.Delegate;
if(appdelegate != null)
{
appdelegate.OrientationLock = orientation;
}
}
public static void LockOrientation(UIInterfaceOrientationMask orientation, UIInterfaceOrientation RotateToOrientation)
{
LockOrientation(orientation);
UIDevice.CurrentDevice.SetValueForKey(new NSNumber((int)RotateToOrientation), new NSString("orientation"));
}
}
View Controller:
public override void ViewDidAppear(bool animated)
{
base.ViewWillAppear(animated);
OrientationUtility.LockOrientation(UIInterfaceOrientationMask.Portrait, UIInterfaceOrientation.Portrait);
}
public override void ViewWillDisappear(bool animated)
{
base.ViewWillDisappear(animated);
OrientationUtility.LockOrientation(UIInterfaceOrientationMask.All);
}
Maybe you can use this code (in C#):
long Kb = 1024;
long Mb = Kb * 1024;
long Gb = Mb * 1024;
long Tb = Gb * 1024;
long Pb = Tb * 1024;
long Eb = Pb * 1024;
if (size < Kb) return size.ToString() + " byte";
if (size < Mb) return (size / Kb).ToString("###.##") + " Kb.";
if (size < Gb) return (size / Mb).ToString("###.##") + " Mb.";
if (size < Tb) return (size / Gb).ToString("###.##") + " Gb.";
if (size < Pb) return (size / Tb).ToString("###.##") + " Tb.";
if (size < Eb) return (size / Pb).ToString("###.##") + " Pb.";
if (size >= Eb) return (size / Eb).ToString("###.##") + " Eb.";
return "invalid size";
There are some already defined data types which allows us to iterate over them easily e.g Array, Map, String Objects
Normal for in iterates over the iterator and in response provides us with the keys that are in the order of insertion as shown in below example.
const numbers = [1,2,3,4,5];
for(let number in number) {
console.log(number);
}
// result: 0, 1, 2, 3, 4
Now if we try same with for of, then in response it provides us with the values not the keys. e.g
const numbers = [1,2,3,4,5];
for(let numbers of numbers) {
console.log(number);
}
// result: 1, 2, 3, 4, 5
So looking at both of the iterators we can easily differentiate the difference between both of them.
Note:- For of only works with the Symbol.iterator
So if we try to iterate over normal object, then it will give us an error e.g-
const Room = {
area: 1000,
height: 7,
floor: 2
}
for(let prop in Room) {
console.log(prop);
}
// Result area, height, floor
for(let prop of Room) {
console.log(prop);
}
Room is not iterable
Now for iterating over we need to define an ES6 Symbol.iterator e.g
const Room= {
area: 1000, height: 7, floor: 2,
[Symbol.iterator]: function* (){
yield this.area;
yield this.height;
yield this.floors;
}
}
for(let prop of Room) {
console.log(prop);
}
//Result 1000, 7, 2
This is the difference between For in and For of. Hope that it might clear the difference.
It's between the Z and the C on your keyboard.
See django docs for views.login(), you supply a 'next' value (as a hidden field) on the input form to redirect to after a successful login.
You have to provide the full path that you want to import.
import com.my.stuff.main.Main; import com.my.stuff.second.*;
So, in your main class, you'd have:
package com.my.stuff.main import com.my.stuff.second.Second; // THIS IS THE IMPORTANT LINE FOR YOUR QUESTION class Main { public static void main(String[] args) { Second second = new Second(); second.x(); } }
EDIT: adding example in response to Shawn D's comment
There is another alternative, as Shawn D points out, where you can specify the full package name of the object that you want to use. This is very useful in two locations. First, if you're using the class exactly once:
class Main {
void function() {
int x = my.package.heirarchy.Foo.aStaticMethod();
another.package.heirarchy.Baz b = new another.package.heirarchy.Bax();
}
}
Alternatively, this is useful when you want to differentiate between two classes with the same short name:
class Main {
void function() {
java.util.Date utilDate = ...;
java.sql.Date sqlDate = ...;
}
}
OpenTK is an improvement over the Tao API, as it uses idiomatic C# style with overloading, strongly-typed enums, exceptions, and standard .NET types:
GL.Begin(BeginMode.Points);
GL.Color3(Color.Yellow);
GL.Vertex3(Vector3.Up);
as opposed to Tao which merely mirrors the C API:
Gl.glBegin(Gl.GL_POINTS); // double "gl" prefix
Gl.glColor3ub(255, 255, 0); // have to pass RGB values as separate args
Gl.glVertex3f(0, 1, 0); // explicit "f" qualifier
This makes for harder porting but is incredibly nice to use.
As a bonus it provides font rendering, texture loading, input handling, audio, math...
Update 18th January 2016: Today the OpenTK maintainer has stepped away from the project, leaving its future uncertain. The forums are filled with spam. The maintainer recommends moving to MonoGame or SDL2#.
Update 30th June 2020: OpenTK has had new maintainers for a while now and has an active discord community. So the previous recommendation of using another library isn't necessarily true.
The example you are referring to is called Upcasting in java.
It creates a subclass object with a super class variable pointing to it.
The variable does not change, it is still the variable of the super class but it is pointing to the object of subclass.
For example lets say you have two classes Machine and Camera ; Camera is a subclass of Machine
class Machine{
public void start(){
System.out.println("Machine Started");
}
}
class Camera extends Machine{
public void start(){
System.out.println("Camera Started");
}
public void snap(){
System.out.println("Photo taken");
}
}
Machine machine1 = new Camera();
machine1.start();
If you execute the above statements it will create an instance of Camera class with a reference of Machine class pointing to it.So, now the output will be "Camera Started"
The variable is still a reference of Machine class. If you attempt machine1.snap();
the code will not compile
The takeaway here is all Cameras are Machines since Camera is a subclass of Machine but all Machines are not Cameras. So you can create an object of subclass and point it to a super class refrence but you cannot ask the super class reference to do all the functions of a subclass object( In our example machine1.snap()
wont compile). The superclass reference has access to only the functions known to the superclass (In our example machine1.start()
). You can not ask a machine reference to take a snap. :)
How to create an array size 5 containing pointers to characters:
char *array_of_pointers[ 5 ]; //array size 5 containing pointers to char
char m = 'm'; //character value holding the value 'm'
array_of_pointers[0] = &m; //assign m ptr into the array position 0.
printf("%c", *array_of_pointers[0]); //get the value of the pointer to m
How to create a pointer to an array of characters:
char (*pointer_to_array)[ 5 ]; //A pointer to an array containing 5 chars
char m = 'm'; //character value holding the value 'm'
*pointer_to_array[0] = m; //dereference array and put m in position 0
printf("%c", (*pointer_to_array)[0]); //dereference array and get position 0
How to create an 2D array containing pointers to characters:

array_of_pointers[4][1] = &m;
//Get position 4 of array, then get position 1, then put m ptr in there.
printf("%c", *array_of_pointers[4][1]);
//Get position 4 of array, then get position 1 and dereference it.
How to create a pointer to an 2D array of characters:

I think the best solution is resize the images via script or locally and upload them again. Remember, you're forcing your viewers to download larger files than they need
In your top Android Studio menu, go to View > Tool Windows > Preview, then it should appear somewhere in the frame of Android Studio, you can move it to the desired place with the dented wheel tool in the Preview frame
new Buffer(number) // Old
Buffer.alloc(number) // New
new Buffer(string) // Old
Buffer.from(string) // New
new Buffer(string, encoding) // Old
Buffer.from(string, encoding) // New
new Buffer(...arguments) // Old
Buffer.from(...arguments) // New
Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.

There are already many nice answers to this problem but I would like to share a wonderful site that I came across when I couldnt solve the 'TesseractNotFound Error: tesseract is not installed or it's not in your path” Please refer this site: https://www.thetopsites.net/article/50655738.shtml
I realised that I got this error because I installed pytesseract with pip but forget to install the binary. You are probably missing tesseract-ocr from your machine. Check the installation instructions here: https://github.com/tesseract-ocr/tesseract/wiki
On a Mac, you can just install using homebrew:
brew install tesseract
It should run fine after that!
Under Windows 10 OS environment, the following method works for me:
Go to this link and Download tesseract and install it. Windows version is available here: https://github.com/UB-Mannheim/tesseract/wiki
Find script file pytesseract.py from C:\Users\User\Anaconda3\Lib\site-packages\pytesseract and open it. Change the following code from tesseract_cmd = 'tesseract' to: tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract.exe' (This is the path where you install Tesseract-OCR so please check where you install it and accordingly update the path)
You may also need to add environment variable C:/Program Files (x86)/Tesseract-OCR/
Hope it works for you!
I know this question is a bit old but i would suggest to use some cachebraking hash in the url of the javascript. This works perfectly in production as well as during development because you can have both infinite cache times and intant updates when changes occur.
Lets assume you have a javascript file /js/script.min.js, but in the referencing html/php file you do not use the actual path but:
<script src="/js/script.<?php echo md5(filemtime('/js/script.min.js')); ?>.min.js"></script>
So everytime the file is changed, the browser gets a different url, which in turn means it cannot be cached, be it locally or on any proxy inbetween.
To make this work you need nginx to rewrite any request to /js/script.[0-9a-f]{32}.min.js to the original filename. In my case i use the following directive (for css also):
location ~* \.(css|js)$ {
expires max;
add_header Pragma public;
etag off;
add_header Cache-Control "public";
add_header Last-Modified "";
rewrite "^/(.*)\/(style|script)\.min\.([\d\w]{32})\.(js|css)$" /$1/$2.min.$4 break;
}
I would guess that the filemtime call does not even require disk access on the server as it should be in linux's file cache. If you have doubts or static html files you can also use a fixed random value (or incremental or content hash) that is updated when your javascript / css preprocessor has finished or let one of your git hooks change it.
In theory you could also use a cachebreaker as a dummy parameter (like /js/script.min.js?cachebreak=0123456789abcfef), but then the file is not cached at least by some proxies because of the "?".
Just hit the same issue and in my case the problem was related to BOM
(byte order mark) at the beginning of the file.
json.tool
would refuse to process even empty file (just curly braces) until i removed the UTF BOM mark.
What I have done is:
set nobomb
)This resolved the problem with json.tool. Hope this helps!

And yet another belated answer.
I couldn't get any output to the console created with AllocConsole
as per earlier suggestions, so instead I'm starting with Console application. Then, if the console is not needed:
[DllImport("kernel32.dll")]
private static extern IntPtr GetConsoleWindow();
[DllImport("user32.dll")]
private static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
private const int SW_HIDE = 0;
private const int SW_SHOW = 5;
[DllImport("user32.dll", SetLastError = true)]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, out int lpdwProcessId);
public static bool HideConsole()
{
var hwnd = GetConsoleWindow();
GetWindowThreadProcessId(hwnd, out var pid);
if (pid != Process.GetCurrentProcess().Id) // It's not our console - don't mess with it.
return false;
ShowWindow(hwnd, SW_HIDE);
return true;
}
Try to bind to the DOMSubtreeModified
event seeign as test is also just part of the DOM.
see this post here on SO:
Found some good answer here regarding reading from console, here another way use 'Scanner' to read from console:
import java.util.Scanner;
String data;
Scanner scanInput = new Scanner(System.in);
data= scanInput.nextLine();
scanInput.close();
System.out.println(data);
The difference between Control.Invoke()
and Control.BeginInvoke()
is,
BeginInvoke()
will schedule the asynchronous action on the GUI thread. When the asynchronous action is scheduled, your code continues. Some time later (you don't know exactly when) your asynchronous action will be executedInvoke()
will execute your asynchronous action (on the GUI thread) and wait until your action has completed.A logical conclusion is that a delegate you pass to Invoke()
can have out-parameters or a return-value, while a delegate you pass to BeginInvoke()
cannot (you have to use EndInvoke to retrieve the results).

POSIX sh doesn't understand ==

The other people saying that brackets aren't supported by sh are wrong, btw.
If you want to use \newcommand
, you can also include \usepackage{xspace}
and define command by \newcommand{\newCommandName}{text to insert\xspace}
.
This can allow you to just use \newCommandName

Whoa. You're really over-complicating it by a very long distance. Try:
>>> print hex(0x12ef ^ 0xabcd)
0xb922
You seem to be ignoring these handy facts, at least:
0x
prefix.hex()
function can be used to convert any number into a hexadecimal string for display.If you already have the numbers as strings, you can use the int()
function to convert to numbers, by providing the expected base (16 for hexadecimal numbers):
>>> print int("12ef", 16)
4874
So you can do two conversions, perform the XOR, and then convert back to hex:
>>> print hex(int("12ef", 16) ^ int("abcd", 16))
0xb922

Same Problem!! Easy and Fastest Solution!! Just remove All breakpoints in debug perspective and reapply breakpoint. Works like a charm!!
Use Math.floor()
:
var f = 20.536;
var i = Math.floor(f); // 20
Python 3 handles strings a bit different. Originally there was just one type for
strings: str
. When unicode gained traction in the '90s the new unicode
type
was added to handle Unicode without breaking pre-existing code1. This is
effectively the same as str
but with multibyte support.
In Python 3 there are two different types:
bytes
type. This is just a sequence of bytes, Python doesn't know
anything about how to interpret this as characters.str
type. This is also a sequence of bytes, but Python knows how to
interpret those bytes as characters.unicode
type was dropped. str
now supports unicode.In Python 2 implicitly assuming an encoding could cause a lot of problems; you
could end up using the wrong encoding, or the data may not have an encoding at
all (e.g. it’s a PNG image).
Explicitly telling Python which encoding to use (or explicitly telling it to
guess) is often a lot better and much more in line with the "Python philosophy"
of "explicit is better than implicit".
This change is incompatible with Python 2 as many return values have changed,
leading to subtle problems like this one; it's probably the main reason why
Python 3 adoption has been so slow. Since Python doesn't have static typing2
it's impossible to change this automatically with a script (such as the bundled
2to3
).
str
to bytes
with bytes('h€llo', 'utf-8')
; this should
produce b'H\xe2\x82\xacllo'
. Note how one character was converted to three
bytes.bytes
to str
with b'H\xe2\x82\xacllo'.decode('utf-8')
.Of course, UTF-8 may not be the correct character set in your case, so be sure to use the correct one.
In your specific piece of code, nextline
is of type bytes
, not str
,
reading stdout
and stdin
from subprocess
changed in Python 3 from str
to
bytes
. This is because Python can't be sure which encoding this uses. It
probably uses the same as sys.stdin.encoding
(the encoding of your system),
but it can't be sure.
You need to replace:
sys.stdout.write(nextline)
with:
sys.stdout.write(nextline.decode('utf-8'))
or maybe:
sys.stdout.write(nextline.decode(sys.stdout.encoding))
You will also need to modify if nextline == ''
to if nextline == b''
since:
>>> '' == b''
False
Also see the Python 3 ChangeLog, PEP 358, and PEP 3112.
1 There are some neat tricks you can do with ASCII that you can't do with multibyte character sets; the most famous example is the "xor with space to switch case" (e.g. chr(ord('a') ^ ord(' ')) == 'A'
) and "set 6th bit to make a control character" (e.g. ord('\t') + ord('@') == ord('I')
). ASCII was designed in a time when manipulating individual bits was an operation with a non-negligible performance impact.
2 Yes, you can use function annotations, but it's a comparatively new feature and little used.
Connect to MySQL
<?php
/*** mysql hostname ***/
$hostname = 'localhost';
/*** mysql username ***/
$username = 'username';
/*** mysql password ***/
$password = 'password';
try {
$dbh = new PDO("mysql:host=$hostname;dbname=mysql", $username, $password);
/*** echo a message saying we have connected ***/
echo 'Connected to database';
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
Also mysqli_connect() function to open a new connection to the MySQL server.
<?php
// Create connection
$con=mysqli_connect(host,username,password,dbname);
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
@Component({
selector: 'drag-drop',
template: `
<h1>Drag 'n Drop</h1>
<div #container

(mouseup)="onMouseButton( container)">
</div>
</div>`,
})
colorRampPalette
could be your friend here:
colfunc <- colorRampPalette(c("black", "white"))
colfunc(10)
# [1] "#000000" "#1C1C1C" "#383838" "#555555" "#717171" "#8D8D8D" "#AAAAAA"
# [8] "#C6C6C6" "#E2E2E2" "#FFFFFF"
And just to show it works:
plot(rep(1,10),col=colfunc(10),pch=19,cex=3)
Yes, you can combine columns easily enough such as concatenating character data:
select col1 | col 2 as bothcols from tbl ...
or adding (for example) numeric data:
select col1 + col2 as bothcols from tbl ...
In both those cases, you end up with a single column bothcols
, which contains the combined data. You may have to coerce the data type if the columns are not compatible.
If we use a template-light-solution (as shown above) like the following:
namespace std {
template<typename T>
std::string to_string(const T &n) {
std::ostringstream s;
s << n;
return s.str();
}
}
Unfortunately, we will have problems in some cases. For example, for static const members:
hpp
class A
{
public:
static const std::size_t x = 10;
A();
};
cpp
A::A()
{
std::cout << std::to_string(x);
}
And linking:
CMakeFiles/untitled2.dir/a.cpp.o:a.cpp:(.rdata$.refptr._ZN1A1xE[.refptr._ZN1A1xE]+0x0): undefined reference to `A::x'
collect2: error: ld returned 1 exit status
Here is one way to solve the problem (add to the type size_t):
namespace std {
std::string to_string(size_t n) {
std::ostringstream s;
s << n;
return s.str();
}
}
HTH.
just double tap 'Shift'
and search for 'Line Numbers'
and there you will see a toggle option on or off
Quick fix for CGRectMake , CGPointMake, CGSizeMake in Swift3 & iOS10
Add these extensions :
extension CGRect{
init(_ x:CGFloat,_ y:CGFloat,_ width:CGFloat,_ height:CGFloat) {
self.init(x:x,y:y,width:width,height:height)
}
}
extension CGSize{
init(_ width:CGFloat,_ height:CGFloat) {
self.init(width:width,height:height)
}
}
extension CGPoint{
init(_ x:CGFloat,_ y:CGFloat) {
self.init(x:x,y:y)
}
}
Then go to "Find and Replace in Workspace" Find CGRectMake , CGPointMake, CGSizeMake and Replace them with CGRect , CGPoint, CGSize
These steps might save all the time as Xcode right now doesn't give us quick conversion from Swift 2+ to Swift 3
If you try this:
#include<stdio.h>
void main()
{
char name[]="siva";
printf("name = %p\n", name);
printf("&name[0] = %p\n", &name[0]);
printf("name printed as %%s is %s\n",name);
printf("*name = %c\n",*name);
printf("name[0] = %c\n", name[0]);
}
Output is:
name = 0xbff5391b
&name[0] = 0xbff5391b
name printed as %s is siva
*name = s
name[0] = s
So 'name' is actually a pointer to the array of characters in memory. If you try reading the first four bytes at 0xbff5391b, you will see 's', 'i', 'v' and 'a'
Location Data
========= ======
0xbff5391b 0x73 's' ---> name[0]
0xbff5391c 0x69 'i' ---> name[1]
0xbff5391d 0x76 'v' ---> name[2]
0xbff5391e 0x61 'a' ---> name[3]
0xbff5391f 0x00 '\0' ---> This is the NULL termination of the string
To print a character you need to pass the value of the character to printf. The value can be referenced as name[0] or *name (since for an array name = &name[0]).
To print a string you need to pass a pointer to the string to printf (in this case 'name' or '&name[0]').
Note, disable wordwrap, otherwise it will not work properly if your lines are longer than sublime's width.
Your second way is correct.
def foo(opts: dict = {}):
pass
print(foo.__annotations__)
this outputs
{'opts': <class 'dict'>}
It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.
I strongly advise against using mutable keyword arguments. More information here.

Do you need to thread this at all ? I'm wondering how big your matrices are, and whether there's any benefit in having one thread print whilst the other does the multiplication.
Perhaps it would be worth measuring this time before doing the relatively complex threading work ?
If you do need to thread it, I would create 'n' threads to perform the multiplication of the cells (perhaps 'n' is the number of cores available to you), and then use the ExecutorService and Future mechanism to dispatch multiple multiplications simultaneously.
That way you can optimise the work based on the number of cores, and you're using the higher level Java threading tools (which should make life easier). Write the results back into a receiving matrix, and then simply print this once all your Future tasks have completed.

To show child or sibling elements it's possible with CSS only. If you use :hover
before combinators (+
, ~
, >
, space
). Then the style applies not to hovered element.
HTML
<body>
<div class="trigger">
Hover here.
</div>
<div class="hidden">
This message shows up.
</div>

CSS
.hidden { display: none; }
.trigger:hover + .hidden { display: inline; }
Or you can simply use javascript code :

if (navigator.appName.indexOf("Microsoft Internet")==-1)
{
if (document.embeds && document.embeds[name])

}
else // if (navigator.appName.indexOf("Microsoft Internet")!=-1)

var vlc = getVLC("vlc");
// do something.
// e.g. vlc.playlist.play();
The best bet with these types of questions is to see exactly what python does. The dis
module is incredibly informative:
>>> import dis
>>> dis.dis("val != None")
1 0 LOAD_NAME 0 (val)
2 LOAD_CONST 0 (None)
4 COMPARE_OP 3 (!=)
6 RETURN_VALUE
>>> dis.dis("not (val is None)")
1 0 LOAD_NAME 0 (val)
2 LOAD_CONST 0 (None)
4 COMPARE_OP 9 (is not)
6 RETURN_VALUE
>>> dis.dis("val is not None")
1 0 LOAD_NAME 0 (val)
2 LOAD_CONST 0 (None)
4 COMPARE_OP 9 (is not)
6 RETURN_VALUE
Notice that the last two cases reduce to the same sequence of operations, Python reads not (val is None)
and uses the is not
operator. The first uses the !=
operator when comparing with None
.
As pointed out by other answers, using !=
when comparing with None
is a bad idea.
just call the finish() in the method you would like to end the activity in, for example when you use the onCreate() method, in the end of the method, just add finish() and you will see the activity ends as soon as it is created!
You can set the format in aspx, just add the property "DateFormatString" in your BoundField.

Here is a nice tutorial, which describes callbacks and the use-case well.
The concept of callbacks is to inform a class synchronous / asynchronous if some work in another class is done. Some call it the Hollywood principle: "Don't call us we call you".
Here's a example:
class A implements ICallback {
MyObject o;
B b = new B(this, someParameter);
@Override
public void callback(MyObject o){
this.o = o;
}
}
class B {
ICallback ic;
B(ICallback ic, someParameter){
this.ic = ic;
}
new Thread(new Runnable(){
public void run(){
// some calculation
ic.callback(myObject)
}
}).start();
}
interface ICallback{
public void callback(MyObject o);
}
Class A calls Class B to get some work done in a Thread. If the Thread finished the work, it will inform Class A over the callback and provide the results. So there is no need for polling or something. You will get the results as soon as they are available.
In Android Callbacks are used f.e. between Activities and Fragments. Because Fragments should be modular you can define a callback in the Fragment to call methods in the Activity.
You need to stop the submission if an error occured:
HTML
<form name ="myform" onsubmit="return validation();">
JS
if (document.myform.username.value == "") {
document.getElementById('errors').innerHTML="*Please enter a username*";
return false;
}
<script>
var listh = document.getElementById( 'list-home-list' );
var hb = document.getElementsByTagName('hb');
$("#list-home-list").click(function(){
$(this).style.color = '#2C2E33';
hb.style.color = 'white';
});
</script>
To put it short 'value' is not an valid attribute of div. So it's absolutely correct to return undefined.
What you could do was something in the line of using one of the HTML5 attributes 'data-*'
<div id="demo" align="center" data-value="1">
And the script would be:
var val = document.getElementById('demo').getAttribute('data-value');
This should work in most modern browsers
Just remember to put your doctype as <!DOCTYPE html>
to get it valid
This one works on Bootstrap 4.3.1.

The HTML code might be a little bit messy because I create a slightly complex dropdown menu for comprehensive test, otherwise everything is pretty straight forward.
Js includes fewer ways to collapse opened dropdowns and CSS only includes minimal styles for full functionalities.

With help of an online xpath tester I'm writing this answer...
For this:
<table id="t2"><tbody>
<tr><td>123</td><td>other</td></tr>
<tr><td>foo</td><td>columns</td></tr>
<tr><td>bar</td><td>are</td></tr>
<tr><td>xyz</td><td>ignored</td></tr>
</tbody></table>
the following xpath:
id("t2") / tbody / tr / td[1]
outputs:
123
foo
bar
xyz
Since 1 means select all td elements which are the first child of their own direct parent.
But the following xpath:
(id("t2") / tbody / tr / td)[1]
outputs:
123
For the case when you know how many columns of data there will be in your CSV file, one simple call to textscan
like Amro suggests will be your best solution.
However, if you don't know a priori how many columns are in your file, you can use a more general approach like I did in the following function. I first used the function fgetl
to read each line of the file into a cell array. Then I used the function textscan
to parse each line into separate strings using a predefined field delimiter and treating the integer fields as strings for now (they can be converted to numeric values later). Here is the resulting code, placed in a function read_mixed_csv
:
function lineArray = read_mixed_csv(fileName, delimiter)
fid = fopen(fileName, 'r'); % Open the file
lineArray = cell(100, 1); % Preallocate a cell array (ideally slightly
% larger than is needed)
lineIndex = 1; % Index of cell to place the next line in
nextLine = fgetl(fid); % Read the first line from the file
while ~isequal(nextLine, -1) % Loop while not at the end of the file
lineArray{lineIndex} = nextLine; % Add the line to the cell array
lineIndex = lineIndex+1; % Increment the line index
nextLine = fgetl(fid); % Read the next line from the file
end
fclose(fid); % Close the file
lineArray = lineArray(1:lineIndex-1); % Remove empty cells, if needed
for iLine = 1:lineIndex-1 % Loop over lines
lineData = textscan(lineArray{iLine}, '%s', ... % Read strings
'Delimiter', delimiter);
lineData = lineData{1}; % Remove cell encapsulation
if strcmp(lineArray{iLine}(end), delimiter) % Account for when the line
lineData{end+1} = ''; % ends with a delimiter
end
lineArray(iLine, 1:numel(lineData)) = lineData; % Overwrite line data
end

Running this function on the sample file content from the question gives this result:
>> data = read_mixed_csv('myfile.csv', ';')
data =
Columns 1 through 7
'04' 'abc' 'def' 'ghj' 'klm' '' ''
'' '' '' '' '' 'Test' 'text'
'' '' '' '' '' 'asdfhsdf' 'dsafdsag'
Columns 8 through 10
'' '' ''
'0xFF' '' ''
'0x0F0F' '' ''
The result is a 3-by-10 cell array with one field per cell where missing fields are represented by the empty string ''
. Now you can access each cell or a combination of cells to format them as you like. For example, if you wanted to change the fields in the first column from strings to integer values, you could use the function str2double
as follows:
>> data(:, 1) = cellfun(@(s) {str2double(s)}, data(:, 1))
data =
Columns 1 through 7
[ 4] 'abc' 'def' 'ghj' 'klm' '' ''
[NaN] '' '' '' '' 'Test' 'text'
[NaN] '' '' '' '' 'asdfhsdf' 'dsafdsag'
Columns 8 through 10
'' '' ''
'0xFF' '' ''
'0x0F0F' '' ''
Note that the empty fields results in NaN
values.
This relies on widely available wget
, present almost everywhere, even on Alpine Linux.
wget --server-response --spider --quiet "${url}" 2>&1 | awk 'NR==1{print $2}'
The explanations are as follow :
--quiet
Turn off Wget's output.
Source - wget man pages
--spider
[ ... ] it will not download the pages, just check that they are there. [ ... ]
Source - wget man pages
--server-response
Print the headers sent by HTTP servers and responses sent by FTP servers.
Source - wget man pages
What they don't say about --server-response
is that those headers output are printed to standard error (sterr), thus the need to redirect to stdin.
The output sent to standard input, we can pipe it to awk
to extract the HTTP status code. That code is :
$2
) non-blank group of characters: {$2}
NR==1
And because we want to print it... {print $2}
.
wget --server-response --spider --quiet "${url}" 2>&1 | awk 'NR==1{print $2}'
Html Code:
<select id="multiple" multiple="multiple" name="multiple">
<option value=""> -- Select -- </option>
<option value="1">Opt1</option>
<option value="2">Opt2</option>
<option value="3">Opt3</option>
<option value="4">Opt4</option>
<option value="5">Opt5</option>
</select>
JQuery Code:
$('#multiple :selected').each(function(i, sel){
alert( $(sel).val() );
});
Hope it works
On top of PoolingHttpClientConnectionManager
along with Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory> create().register("https", sslFactory).build();
If you want an asynchronous httpclient using PoolingNHttpClientConnectionManager
the code shoudl be similar to following
SSLContextBuilder builder = SSLContexts.custom();
builder.loadTrustMaterial(null, new TrustStrategy() {
@Override
public boolean isTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
return true;
}
});
SSLContext sslContext = builder.build();
SchemeIOSessionStrategy sslioSessionStrategy = new SSLIOSessionStrategy(sslContext,
new HostnameVerifier(){
@Override
public boolean verify(String hostname, SSLSession session) {
return true;// TODO as of now allow all hostnames
}
});
Registry<SchemeIOSessionStrategy> sslioSessionRegistry = RegistryBuilder.<SchemeIOSessionStrategy>create().register("https", sslioSessionStrategy).build();
PoolingNHttpClientConnectionManager ncm = new PoolingNHttpClientConnectionManager(new DefaultConnectingIOReactor(),sslioSessionRegistry);
CloseableHttpAsyncClient asyncHttpClient = HttpAsyncClients.custom().setConnectionManager(ncm).build();
asyncHttpClient.start();
I followed BEN and Thanks and Lot for the Answer,So I used his idea to get my solution, I am posting the same hence if some one else has similar requirement, then you also can use my solution as well, My requirement was something like I want to get the sum of entire data from the first row to the last row, and I was generating the spreadsheet programmatically so don't and can't hard code the row names in sum as the data is always dynamic and number of rows are never constant. My formula was something like as follows.
=SUM(B1:INDIRECT("B"&ROW()-4))
I am just updating this with Microsoft SQL Server Management Studio 2008 R2 version. if you run the installer normally, you can just add Management Tools – Basic, and by clicking Basic it should select Management Tools – Complete.
That is what worked for me.
Similar setup, identical problem. Some installations would work, but most would start redirecting (http 302) to /Account/Login?ReturnUrl=%2f after a successful login, even though we're not using Forms Authentication. In my case after trying everything else, the solution was to switch the Application Pool Managed Pipeline Mode from from Integrated to Classic, which cleared up the problem immediately.
select * from [member] where DatePart("m", date_created) = DatePart("m", DateAdd("m", -1, getdate())) AND DatePart("yyyy", date_created) = DatePart("yyyy", DateAdd("m", -1, getdate()))
The comments above are correct. You're missing the decorators. If you want a generic deserializer you can use this.
public static T DeserializeXMLFileToObject<T>(string XmlFilename)
{
T returnObject = default(T);
if (string.IsNullOrEmpty(XmlFilename)) return default(T);
try
{
StreamReader xmlStream = new StreamReader(XmlFilename);
XmlSerializer serializer = new XmlSerializer(typeof(T));
returnObject = (T)serializer.Deserialize(xmlStream);
}
catch (Exception ex)
{
ExceptionLogger.WriteExceptionToConsole(ex, DateTime.Now);
}
return returnObject;
}
Then you'd call it like this:
MyObjType MyObj = DeserializeXMLFileToObject<MyObjType>(FilePath);
Other than ERRORLEVEL, batch files have no error handling. You'd want to look at a more powerful scripting language. I've been moving code to PowerShell.
The ability to easily use .Net assemblies and methods was one of the major reasons I started with PowerShell. The improved error handling was another. The fact that Microsoft is now requiring all of its server programs (Exchange, SQL Server etc) to be PowerShell drivable was pure icing on the cake.
Right now, it looks like any time invested in learning and using PowerShell will be time well spent.
You can also use BigInteger for variable length bytes. You can convert it to long, int or short, whichever suits your needs.
new BigInteger(bytes).intValue();
or to denote polarity:
new BigInteger(1, bytes).intValue();
To get bytes back just:
new BigInteger(bytes).toByteArray()
Starting from pandas 0.14 (released end of May 2014), postgresql is supported. The sql
module now uses sqlalchemy
to support different database flavors. You can pass a sqlalchemy engine for a postgresql database (see docs). E.g.:
from sqlalchemy import create_engine
engine = create_engine('postgresql://username:password@localhost:5432/mydatabase')
df.to_sql('table_name', engine)
You are correct that in pandas up to version 0.13.1 postgresql was not supported. If you need to use an older version of pandas, here is a patched version of pandas.io.sql
: https://gist.github.com/jorisvandenbossche/10841234.
I wrote this a time ago, so cannot fully guarantee that it always works, buth the basis should be there). If you put that file in your working directory and import it, then you should be able to do (where con
is a postgresql connection):
import sql # the patched version (file is named sql.py)
sql.write_frame(df, 'table_name', con, flavor='postgresql')
I would recommend using Properties.Settings to store values like ConnectionStrings and so on inside of the class library. This is where all the connection strings are stores in by suggestion from visual studio when you try to add a table adapter for example. enter image description here
And then they will be accessible by using this code every where in the clas library
var cs= Properties.Settings.Default.[<name of defined setting>];
I always use the iPhone configuration utility for this. Allows much more control and is faster - you don't have to sync the whole device.
while the above answers didn't solve my problem. I finally solved it by specifically going to this link https://www.microsoft.com/net/download/visual-studio-sdks and download the required sdk for Visual Studio. It was really confusing and i don't understand why but that solved my problem
scanner.useDelimiter(",");
This should work.

If you want to get advantage of your local machine timezone you can use myDateTime.ToUniversalTime()
to get the UTC time from your local time or myDateTime.ToLocalTime()
to convert the UTC time to the local machine's time.
// convert UTC time from the database to the machine's time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var localTime = databaseUtcTime.ToLocalTime();
// convert local time to UTC for database save
var databaseUtcTime = localTime.ToUniversalTime();
If you need to convert time from/to other timezones, you may use TimeZoneInfo.ConvertTime()
or TimeZoneInfo.ConvertTimeFromUtc()
.
// convert UTC time from the database to japanese time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var japaneseTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
var japaneseTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, japaneseTimeZone);
// convert japanese time to UTC for database save
var databaseUtcTime = TimeZoneInfo.ConvertTimeToUtc(japaneseTime, japaneseTimeZone);

My personal preference for LaTeX on Linux has been the KDE-based editor Kile.
Just go into the build path and change the source path to be src/prefix1
instead of src
.
It may be easiest to right-click on the src
directory and select "Build Path / Remove from build path", then find the src/prefix1
directory, right-click it and select "Build Path / Use as source folder".
Here is a way to do it without adding an ID to the form elements.
<form method="post">
...
<select name="List">
<option value="1">Test1</option>
<option value="2">Test2</option>
</select>
<select name="List">
<option value="3">Test3</option>
<option value="4">Test4</option>
</select>
...
</form>
public ActionResult OrderProcessor()
{
string[] ids = Request.Form.GetValues("List");
}
Then ids will contain all the selected option values from the select lists. Also, you could go down the Model Binder route like so:
public class OrderModel
{
public string[] List { get; set; }
}
public ActionResult OrderProcessor(OrderModel model)
{
string[] ids = model.List;
}
Hope this helps.
The modulus is a mathematical operation, sometimes described as "clock arithmetic." I find that describing it as simply a remainder is misleading and confusing because it masks the real reason it is used so much in computer science. It really is used to wrap around cycles.
Think of a clock: Suppose you look at a clock in "military" time, where the range of times goes from 0:00 - 23.59. Now if you wanted something to happen every day at midnight, you would want the current time mod 24 to be zero:
if (hour % 24 == 0):
You can think of all hours in history wrapping around a circle of 24 hours over and over and the current hour of the day is that infinitely long number mod 24. It is a much more profound concept than just a remainder, it is a mathematical way to deal with cycles and it is very important in computer science. It is also used to wrap around arrays, allowing you to increase the index and use the modulus to wrap back to the beginning after you reach the end of the array.
If you don't need much in the way of custom behavior, JOptionPane is a good time saver. It takes care of the placement and localization of OK / Cancel options, and is a quick-and-dirty way to show a custom dialog without needing to define your own classes. Most of the time the "message" parameter in JOptionPane is a String, but you can pass in a JComponent or array of JComponents as well.
Example:
JTextField firstName = new JTextField();
JTextField lastName = new JTextField();
JPasswordField password = new JPasswordField();
final JComponent[] inputs = new JComponent[] {
new JLabel("First"),
firstName,
new JLabel("Last"),
lastName,
new JLabel("Password"),
password
};
int result = JOptionPane.showConfirmDialog(null, inputs, "My custom dialog", JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.OK_OPTION) {
System.out.println("You entered " +
firstName.getText() + ", " +
lastName.getText() + ", " +
password.getText());
} else {
System.out.println("User canceled / closed the dialog, result = " + result);
}
The grep utility is not needed. Awk can do it all:
netstat -rn | awk '/default/ {print $2}'
192.168.128.1
Note that if you have something like Parallels (or a VPN, or both) running, you may see two or more default routing entries - it will be true if you use the 'grep' suggestion above, too.
netstat -rn | awk '/default/ {print $2}'
192.168.128.1
link#12
and
netstat -rn | awk '/default/ {print $2}'
utun1
192.168.128.1
link#12
To set a variable (_default) for further use (assuming only one entry for 'default') .....
_default=$( netstat -rn inet | awk '/default/ {print $2}' ) # I prefer $( ... ) over back-ticks
In the case of multiple default routes use:
netstat -rn | awk '/default/ {if ( index($6, "en") > 0 ){print $2} }'
192.168.128.1
These examples tested in Mavericks Terminal.app and are specific to OSX only. For example, other *nix versions frequently use 'eth' for ethernet/wireless connections, not 'en'. This is also only tested with ksh. Other shells may need a slightly different syntax.
<?php
$j=1;
array_reverse($skills_nav);

$a = '<li><a href="#" data-filter=".'.$skill->slug.'">';
$a .= $skill->name;
$a .= '</a></li>';
echo $a;
echo "\n";
$j++;

The SQLite equivalent of anything this robust is a tangled weave of substr
and instr
calls that you should avoid.
Another cause of "TCP ACKed Unseen" is the number of packets that may get dropped in a capture. If I run an unfiltered capture for all traffic on a busy interface, I will sometimes see a large number of 'dropped' packets after stopping tshark.
On the last capture I did when I saw this, I had 2893204 packets captured, but once I hit Ctrl-C, I got a 87581 packets dropped message. Thats a 3% loss, so when wireshark opens the capture, its likely to be missing packets and report "unseen" packets.
As I mentioned, I captured a really busy interface with no capture filter, so tshark had to sort all packets, when I use a capture filter to remove some of the noise, I no longer get the error.
Some JavaScript engines can parse that format directly, which makes the task pretty easy:
function convertDate(inputFormat) {_x000D_
function pad(s) { return (s < 10) ? '0' + s : s; }_x000D_
var d = new Date(inputFormat)_x000D_
return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/')_x000D_
}_x000D_
_x000D_
console.log(convertDate('Mon Nov 19 13:29:40 2012')) // => "19/11/2012"

set { electricFanRate = value; }

How to create the table of dates (and a super fast way to create a numbers table)
/*Gets a list of integers into a temp table (Jeff Moden's idea from SqlServerCentral.com)*/
SELECT TOP 10950 /*30 years of days*/
IDENTITY(INT,1,1) as N
INTO #Numbers
FROM Master.dbo.SysColumns sc1,
Master.dbo.SysColumns sc2
/*Create the dates table*/
CREATE TABLE [TableOfDates](
[fld_date] [datetime] NOT NULL,
CONSTRAINT [PK_TableOfDates] PRIMARY KEY CLUSTERED
(
[fld_date] ASC
)WITH FILLFACTOR = 99 ON [PRIMARY]
) ON [PRIMARY]
/*fill the table with dates*/
DECLARE @daysFromFirstDateInTheTable int
DECLARE @firstDateInTheTable DATETIME
SET @firstDateInTheTable = '01/01/1998'
SET @daysFromFirstDateInTheTable = (SELECT (DATEDIFF(dd, @firstDateInTheTable ,GETDATE()) + 1))
INSERT INTO
TableOfDates
SELECT
DATEADD(dd,nums.n - @daysFromFirstDateInTheTable, CAST(FLOOR(CAST(GETDATE() as FLOAT)) as DateTime)) as FLD_Date
FROM #Numbers nums
Now that you have a table of dates, you can use a function (NOT A PROC) like KM's to get the table of them.
CREATE FUNCTION dbo.ListDates
(
@StartDate DATETIME
,@EndDate DATETIME
)
RETURNS
@DateList table
(
Date datetime
)
AS
BEGIN
/*add some validation logic of your own to make sure that the inputs are sound.Adjust the rest as needed*/
INSERT INTO
@DateList
SELECT FLD_Date FROM TableOfDates (NOLOCK) WHERE FLD_Date >= @StartDate AND FLD_Date <= @EndDate
RETURN

Using an iframe
to "render" a PDF will not work on all browsers; it depends on how the browser handles PDF files. Some browsers (such as Firefox and Chrome) have a built-in PDF rendered which allows them to display the PDF inline where as some older browsers (perhaps older versions of IE attempt to download the file instead).
Instead, I recommend checking out PDFObject which is a Javascript library to embed PDFs in HTML files. It handles browser compatibility pretty well and will most likely work on IE8.
In your HTML, you could set up a div
to display the PDFs:
<div id="pdfRenderer"></div>
Then, you can have Javascript code to embed a PDF in that div
:
var pdf = new PDFObject({
url: "https://something.com/HTC_One_XL_User_Guide.pdf",
id: "pdfRendered",
pdfOpenParams: {
view: "FitH"
}
}).embed("pdfRenderer");
Or as a single command:
git push -u origin master:my_test
Pushes the commits from your local master branch to a (possibly new) remote branch my_test
and sets up master
to track origin/my_test
.

A compiler consists of two major blocks: the 'front end' and the 'back end'. The front end of a compiler analyzes the source code and builds some form of a 'intermediary representation' of said source code which is much easier to analyze by a machine algorithm than is the source code (i.e. whereas the source code e.g. C++ is designed to help the human programmer to write code, the intermediary form is designed to help simplify the algorithm that analyzes said intermediary form easier). The back end of a compiler takes the intermediary form and then converts it to a 'target language'.
Now, the target language for general-use compilers are assembler languages for various processors, but there's nothing to prohibit a compiler back end to produce code in some other language, for as long as said target language is (at least) as flexible as a general CPU assembler.
Now, as you can probably imagine, C is definitely as flexible as a CPU's assembler, such that a C++ to C compiler is really no problem to implement from a technical pov.
So you have: C++ ---frontEnd---> someIntermediaryForm ---backEnd---> C
You may want to check these guys out: http://www.edg.com/index.php?location=c_frontend (the above link is just informative for what can be done, they license their front ends for tens of thousands of dollars)
PS As far as i know, there is no such a C++ to C compiler by GNU, and this totally beats me (if i'm right about this). Because the C language is fairly small and it's internal mechanisms are fairly rudimentary, a C compiler requires something like one man-year work (i can tell you this first hand cause i wrote such a compiler myself may years ago, and it produces a [virtual] stack machine intermediary code), and being able to have a maintained, up-to-date C++ compiler while only having to write a C compiler once would be a great thing to have...
The following solution is not a single statement for altering multiple columns, but yes, it makes life simple:
Generate a table's CREATE
script.
Replace CREATE TABLE
with ALTER TABLE [TableName] ALTER COLUMN
for first line
Remove unwanted columns from list.
Change the columns data types as you want.
Perform a Find and Replace… as follows:
NULL
,NULL; ALTER TABLE [TableName] ALTER COLUMN
Run the script.
Hope it will save lot of time :))
If you want it as a string (for example, a 10-digit phone number) you can use this:
n = 10
''.join(["{}".format(randint(0, 9)) for num in range(0, n)])
With current versions of Docker, you can use the --device
flag to achieve what you want, without needing to give access to all USB devices.
For example, if you wanted to make only /dev/ttyUSB0
accessible within your Docker container, you could do something like:
docker run -t -i --device=/dev/ttyUSB0 ubuntu bash
Instead of SELECT * FROM table1 WHERE ID IN (1,2,3,4,...,1000);
Use this :
SELECT * FROM table1 WHERE ID IN (SELECT rownum AS ID FROM dual connect BY level <= 1000);
*Note that you need to be sure the ID does not refer any other foreign IDS if this is a dependency. To ensure only existing ids are available then :
SELECT * FROM table1 WHERE ID IN (SELECT distinct(ID) FROM tablewhereidsareavailable);

In Bootstrap, the .btn
class has a white-space: nowrap;
property, making it so that the button text won't wrap. So, after setting that to normal
, and giving the button a width
, the text should wrap to the next line if the text would exceed the set width
.
#new-board-btn {
white-space: normal;
}
Sharer.php no longer allows you to customize. The page you share will be scraped for OG Tags and that data will be shared.
To properly customize, use FB.UI

A for
loop:
for(INIT; TEST; ADVANCE) {
BODY
}
Means the following:
INIT;
while (true) {
if (!TEST)
break;
BODY;
ADVANCE;
}
You can write almost any expression for INIT
, TEST
, ADVANCE
, and BODY
.
Do note that the ++
operators and variants are operators with side-effects (one should try to avoid them if you are not using them like i+=1
and the like):
++i
means i+=1; return i
i++
means oldI=i; i+=1; return oldI
Example:
> i=0
> [i++, i, ++i, i, i--, i, --i, i]
[0, 1, 2, 2, 2, 1, 0, 0]

Noticed your comment about using it for email validation and needing a plugin, the validation plugin may help you, its located at http://bassistance.de/jquery-plugins/jquery-plugin-validation/, it comes with a e-mail rule as well.
You can change that default behavior in your .gitconfig
, for example:
[push]
default = current
To check the current settings, run:
git config --global --get push.default
function mode(array){
var set = Array.from(new Set(array));
var counts = set.map(a=>array.filter(b=>b==a).length);
var indices = counts.map((a,b)=>Math.max(...counts)===a?b:0).filter(b=>b!==0);
var mode = indices.map(a=>set[a]);
return mode;
}
This may be an incorrect parameter to your SOAP call; look at the format of the parameter(s) in the 'data:' json section - this is the payload you are passing over - parameter and data wrapped in JSON format.

This happened to me because Xcode didn't appear to like me using the same variable name in two different classes (that conform to the same protocol, if that matters, although the variable name has nothing related in any protocol). I simply renamed my new variable.

I use GenMyModel, first released in 2013. It's a real UML modeler, not a drawing tool. Your diagrams are UML-compliant, generate code and can be exported as UML/XMI files. It's web-based and free so it matches your criteria.
Other possibility would be place the html in a non overflow:hidden element placed 'out' of screen, like a position absolute top and left lesse then 5000px, then read this elements height. Its ugly, but work well.
Wow, there are some complex solutions here. So complex I decided to come up with something simpler but also quite powerful. Here it is;
function sortByPriority(data, priorities) {
if (priorities.length == 0) {
return data;
}
const nextPriority = priorities[0];
const remainingPriorities = priorities.slice(1);
const matched = data.filter(item => item.hasOwnProperty(nextPriority));
const remainingData = data.filter(item => !item.hasOwnProperty(nextPriority));
return sortByPriority(matched, remainingPriorities)
.sort((a, b) => (a[nextPriority] > b[nextPriority]) ? 1 : -1)
.concat(sortByPriority(remainingData, remainingPriorities));
}
And here is an example of how you use it.
const data = [
{ id: 1, mediumPriority: 'bbb', lowestPriority: 'ggg' },
{ id: 2, highestPriority: 'bbb', mediumPriority: 'ccc', lowestPriority: 'ggg' },
{ id: 3, mediumPriority: 'aaa', lowestPriority: 'ggg' },
];
const priorities = [
'highestPriority',
'mediumPriority',
'lowestPriority'
];
const sorted = sortByPriority(data, priorities);
This will first sort by the precedence of the attributes, then by the value of the attributes.
Improving on Vincent's answer, I wrote a script to do that: xcodearchive
It allows you to archive (generate an ipa) your project via the command line.
Think of it like the sister of the xcodebuild
command, but for archiving.
Code is available on github: http://github.com/gcerquant/xcodearchive
One option of the script is to enable the archiving of the dSYM symbols in a timestamped archive. No excuse to not keep the symbols anymore, and not be able to symbolicate the crash log you might later receive.
Use the PHP function
void set_time_limit ( int $seconds )
The maximum execution time, in seconds. If set to zero, no time limit is imposed.
This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.

From Spring Boot Reference Guide
Installation as an init.d service (System V)
Simply symlink the jar to
init.d
to support the standardstart
,stop
,restart
andstatus
commands. Assuming that you have a Spring Boot application installed in /var/myapp, to install a Spring Boot application as an init.d service simply create a symlink:$ sudo ln -s /var/myapp/myapp.jar /etc/init.d/myapp
Once installed, you can start and stop the service in the usual way. For example, on a Debian based system:
$ service myapp start
If your application fails to start, check the log file written to
/var/log/<appname>.log
for errors.
Continue reading to know how to secure a deployed service.
After doing as written I've discovered that my service fails to start with this error message in logs: start-stop-daemon: unrecognized option --no-close. And I've managed to fix it by creating a config file /var/myapp/myapp.conf
with the following content
USE_START_STOP_DAEMON=false
Because Xcode subsumes the CLI tools if installed first, I use the following hybrid which has been validated on 10.12 and 10.14. I expect it works on a lot of other versions:
installed=$(pkgutil --pkg-info=com.apple.pkg.CLTools_Executables 2>/dev/null || pkgutil --pkg-info=com.apple.pkg.Xcode)
Salt with awk
to taste for branching logic.
Of course xcode-select -p
handles the variations with a really short command but fails to give the detailed package, version, and installation date metadata.
To answer your question, and get the Prefix
too, for MySQL you can do:
select Prefix, CR, length(CR) from table1 order by length(CR) DESC limit 1;
and it will return

+-------+----------------------------+--------------------+
| g | ;#WR_1;#WR_2;#WR_3;#WR_4;# | 26 |

numba
For recursive calculations which are not vectorisable, numba
, which uses JIT-compilation and works with lower level objects, often yields large performance improvements. You need only define a regular for
loop and use the decorator @njit
or (for older versions) @jit(nopython=True)
:
For a reasonable size dataframe, this gives a ~30x performance improvement versus a regular for
loop:
from numba import jit
@jit(nopython=True)
def calculator_nb(a, b, d):
res = np.empty(d.shape)
res[0] = d[0]
for i in range(1, res.shape[0]):
res[i] = res[i-1] * a[i] + b[i]
return res
df['C'] = calculator_nb(*df[list('ABD')].values.T)
n = 10**5
df = pd.concat([df]*n, ignore_index=True)
# benchmarking on Python 3.6.0, Pandas 0.19.2, NumPy 1.11.3, Numba 0.30.1
# calculator() is same as calculator_nb() but without @jit decorator
%timeit calculator_nb(*df[list('ABD')].values.T) # 14.1 ms per loop
%timeit calculator(*df[list('ABD')].values.T) # 444 ms per loop
In MySQL TRUE
and FALSE
are synonyms for TINYINT(1)
.
So therefore its basically the same thing, but MySQL is converting to 0/1 - so just use a TINYINT
if that's easier for you
P.S.
The performance is likely to be so minuscule (if at all), that if you need to ask on StackOverflow, then it won't affect your database :)
Combining the advice from MartinP and user664833, I was also able to get it to work. Caveat is that entering psql from the pgAdmin GUI tool via choosing Plugins...PSQL Console sets the credentials and permission level for the psql session, so you must have Admin or CRUD permissions on the table and maybe also Admin on the DB (do not know for sure on that). The command then in the psql console would take this form:
postgres=# \i driveletter:/folder_path/backupfilename.backup
where postgres=# is the psql prompt, not part of the command.
The .backup file will include the commands used to create the table, so you may also get things like "ALTER TABLE ..." commands in the file that get executed but reported as errors. I suppose you can always delete these commands before running the restore but you're probably better safe than sorry to keep them in there, as these will not likely cause the restore of data to fail. But always check to be sure the data you wanted to resore actually got there. (Sorry if this seems like patronizing advice to anyone, but it's an oversight that can happen to anyone no matter how long they have been at this stuff -- a moment's distraction from a colleague, a phone call, etc., and it's easy to forget this step. I have done it myself using other databases earlier in my career and wondered "Gee, why am I not seeing any data back from this query?" Answer was the data never actually got restored, and I just wasted 2 hours trying to hunt down suspected possible bugs that didn't exist.)
I'm working with .NET 4.5 and couldn't get this working... I was using WPF Custom Control Library. This worked for me in the end...

type ModifiedType = Modify<OriginalType, { a: number; b: number; }> interface ModifiedInterface extends Modify<OriginalType, { a: number; b: number; }> {}
Inspired by ZSkycat's extends Omit
solution, I came up with this:
type Modify<T, R> = Omit<T, keyof R> & R; // before [email protected] type Modify<T, R> = Pick<T, Exclude<keyof T, keyof R>> & R
Example:
interface OriginalInterface {
a: string;
b: boolean;
c: number;
}
type ModifiedType = Modify<OriginalInterface , {
a: number;
b: number;
}>
// ModifiedType = { a: number; b: number; c: number; }
Going step by step:
type R0 = Omit<OriginalType, 'a' | 'b'> // { c: number; }
type R1 = R0 & {a: number, b: number } // { a: number; b: number; c: number; }
type T0 = Exclude<'a' | 'b' | 'c' , 'a' | 'b'> // 'c'
type T1 = Pick<OriginalType, T0> // { c: number; }
type T2 = T1 & {a: number, b: number } // { a: number; b: number; c: number; }
This was the shortest way I could find to sort a DataTable without having to create any new variables.
DataTable.DefaultView.Sort = "ColumnName ASC"
DataTable = DataTable.DefaultView.ToTable
Where:
ASC - Ascending
DESC - Descending
ColumnName - The column you want to sort by
DataTable - The table you want to sort

git rm --fileName

You can use the explode function as follows:
$myvalue = 'Test me more';
$arr = explode(' ',trim($myvalue));
echo $arr[0]; // will print Test
If you are unsure of the size of the array or if it can change you can do this to have a static array.
ArrayList<Player> thePlayersList = new ArrayList<Player>();
thePlayersList.add(new Player(1));
thePlayersList.add(new Player(2));
.
.
//Some code here that changes the number of players e.g
Players[] thePlayers = thePlayersList.toArray();
The 487 Response indicates that the previous request was terminated by user/application action. The most common occurrence is when the CANCEL happens as explained above. But it is also not limited to CANCEL. There are other cases where such responses can be relevant. So it depends on where you are seeing this behavior and whether its a user or application action that caused it.
15.1.2 UAS Behavior==> BYE Handling in RFC 3261
The UAS MUST still respond to any pending requests received for that dialog. It is RECOMMENDED that a 487 (Request Terminated) response be generated to those pending requests.

I struggled a lot trying to implement posting a image from Android client to servlet using httpclient-4.3.5.jar, httpcore-4.3.2.jar, httpmime-4.3.5.jar. I always got a runtime error. I found out that basically you cannot use these jars with Android as Google is using older version of HttpClient in Android. The explanation is here http://hc.apache.org/httpcomponents-client-4.3.x/android-port.html. You need to get the httpclientandroidlib-1.2.1 jar from android http-client library. Then change your imports from or.apache.http.client to ch.boye.httpclientandroidlib. Hope this helps.
If you don't care about any child elements, e.g. optgroup
, you can use empty()
...
$('select').empty();
Otherwise, if you only want option
elements removed, use remove()
.
$('select option').remove();
In Ghost4J library (http://ghost4j.sourceforge.net), since version 0.4.0 you can use a SimpleRenderer to do the job with few lines of code:
Load PDF or PS file (use PSDocument class for that):
PDFDocument document = new PDFDocument();
document.load(new File("input.pdf"));
Create the renderer
SimpleRenderer renderer = new SimpleRenderer();
// set resolution (in DPI)
renderer.setResolution(300);
Render
List<Image> images = renderer.render(document);
Then you can do what you want with your image objects, for example, you can write them as PNG like this:
for (int i = 0; i < images.size(); i++) {
ImageIO.write((RenderedImage) images.get(i), "png", new File((i + 1) + ".png"));
}
Note: Ghost4J uses the native Ghostscript C API so you need to have a Ghostscript installed on your box.
I hope it will help you :)
If you don't mind a third party dependency, there is a class named Collectors2 in Eclipse Collections which contains methods returning Collectors for summing and summarizing BigDecimal and BigInteger. These methods take a Function as a parameter so you can extract a BigDecimal or BigInteger value from an object.
List<BigDecimal> list = mList(
BigDecimal.valueOf(0.1),
BigDecimal.valueOf(1.1),
BigDecimal.valueOf(2.1),
BigDecimal.valueOf(0.1));
BigDecimal sum =
list.stream().collect(Collectors2.summingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), sum);
BigDecimalSummaryStatistics statistics =
list.stream().collect(Collectors2.summarizingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), statistics.getSum());
Assert.assertEquals(BigDecimal.valueOf(0.1), statistics.getMin());
Assert.assertEquals(BigDecimal.valueOf(2.1), statistics.getMax());
Assert.assertEquals(BigDecimal.valueOf(0.85), statistics.getAverage());
Note: I am a committer for Eclipse Collections.
the event property seems to be string first you have to parse it to json :
var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' };
var event = JSON.parse(req.mandrill_events);
var ts = event[0].ts
You're missing an ending anchor.

You have to pass the -np
/--no-parent
option to wget
(in addition to -r
/--recursive
, of course), otherwise it will follow the link in the directory index on my site to the parent directory. So the command would look like this:
wget --recursive --no-parent http://example.com/configs/.vim/
To avoid downloading the auto-generated index.html
files, use the -R
/--reject
option:
wget -r -np -R "index.html*" http://example.com/configs/.vim/
If you only need the date and not the time use:
select*from table where exec_datetime
between subdate(curdate(), 30)and curdate();
Since curdate()
omits the time component, it's potentially faster than now()
and more "semantically correct" in cases where you're only interested in the date.
Also, subdate()
's 2-arity overload is potentially faster than using interval
.
interval
is meant to be for cases when you need a non-day component.
Realised that I was using OpenJDK when I saw this error. Fixed it once I installed the Oracle JDK instead.
Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:
EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")
After that you can do this:
EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )
R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.
I think the full validate function should look like this:
from datetime import datetime
def validate(date_text):
try:
if date_text != datetime.strptime(date_text, "%Y-%m-%d").strftime('%Y-%m-%d'):
raise ValueError
return True
except ValueError:
return False
Executing just
datetime.strptime(date_text, "%Y-%m-%d")
is not enough because strptime method doesn't check that month and day of the month are zero-padded decimal numbers. For example
datetime.strptime("2016-5-3", '%Y-%m-%d')
will be executed without errors.

I have a hilarious story for all. After reaching this page I said "Eureka! I'm saved. That MUST be my problem." So I inserted the required ALLOWED_HOSTS
list in setting.py and... nothing. Same old 500 error. And no, it wasn't for lack of a 404.html file.
So for 2 days I busied myself with wild theories, such as that it had something to do with serving static files (understand that I am a noob and noobs don't know what they're doing).
So what was it? It is now Mr. Moderator that we come to a useful tip. Whereas my development Django is version 1.5.something, my production server version is 1.5.something+1... or maybe plus 2. Whatever. And so after I added the ALLOWED_HOSTS
to the desktop version of settings.py, which lacked what hwjp requested--- a "default value in settings.py, perhaps with an explanatory comment"--- I did the same on the production server with the proper domain for it.
But I failed to notice that on the production server with the later version of Django there WAS a default value in settings.py with an explanatory comment. It was well below where I made my entry, out of sight on the monitor. And of course the list was empty. Hence my waste of time.
In regards to the question in your comment:
Assuming that you've previously bound your function to the click event of the radio button, add this to your $(document).ready

$('#[radioButtonOptionID]').click()
Without a parameter, that simulates the click event.

Operators first()
and take(1)
aren't the same.
The first()
operator takes an optional predicate
function and emits an error
notification when no value matched when the source completed.
For example this will emit an error:
import { EMPTY, range } from 'rxjs';
import { first, take } from 'rxjs/operators';
EMPTY.pipe(
first(),
).subscribe(console.log, err => console.log('Error', err));
... as well as this:
range(1, 5).pipe(
first(val => val > 6),
).subscribe(console.log, err => console.log('Error', err));
While this will match the first value emitted:
range(1, 5).pipe(
first(),
).subscribe(console.log, err => console.log('Error', err));
On the other hand take(1)
just takes the first value and completes. No further logic is involved.
range(1, 5).pipe(
take(1),
).subscribe(console.log, err => console.log('Error', err));
Then with empty source Observable it won't emit any error:
EMPTY.pipe(
take(1),
).subscribe(console.log, err => console.log('Error', err));

I don't see a way to run a single untagged test within a test class but I am providing my workflow since it seems to be useful for anyone who runs into this question.
From within a sbt session:
test:testOnly *YourTestClass
(The asterisk is a wildcard, you could specify the full path com.example.specs.YourTestClass
.)
All tests within that test class will be executed. Presumably you're most concerned with failing tests, so correct any failing implementations and then run:
test:testQuick
... which will only execute tests that failed. (Repeating the most recently executed test:testOnly
command will be the same as test:testQuick
in this case, but if you break up your test methods into appropriate test classes you can use a wildcard to make test:testQuick
a more efficient way to re-run failing tests.)
Note that the nomenclature for test in ScalaTest is a test class, not a specific test method, so all untagged methods are executed.
If you have too many test methods in a test class break them up into separate classes or tag them appropriately. (This could be a signal that the class under test is in violation of single responsibility principle and could use a refactoring.)
If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900
If your date is text and you need to convert it then DATEVALUE
will do this:
You might implement your class model by composition, having the book object have a map of chapter objects contained within it (map chapter number to chapter object). Your search function could be given a list of books into which to search by asking each book to search its chapters. The book object would then iterate over each chapter, invoking the chapter.search() function to look for the desired key and return some kind of index into the chapter. The book's search() would then return some data type which could combine a reference to the book and some way to reference the data that it found for the search. The reference to the book could be used to get the name of the book object that is associated with the collection of chapter search hits.
Here's what I would use:
(?<!\S)stackoverflow(?!\S)
In other words, match "stackoverflow" if it's not preceded by a non-whitespace character and not followed by a non-whitespace character.
This is neater (IMO) than the "space-or-anchor" approach, and it doesn't assume the string starts and ends with word characters like the \b
approach does.

'type' => 'INNER',
'conditions' => array(
'ServiceImage.service_id' =>'Service.id'
)
),
),
)
);
It goges to array is null.

Java is compiled to bytecode, which then goes into the Java VM, which interprets it.

Simply put, an endpoint is one end of a communication channel. When an API interacts with another system, the touch-points of this communication are considered endpoints. For APIs, an endpoint can include a URL of a server or service. Each endpoint is the location from which APIs can access the resources they need to carry out their function.
APIs work using ‘requests’ and ‘responses.’ When an API requests information from a web application or web server, it will receive a response. The place that APIs send requests and where the resource lives, is called an endpoint.

Your document should not contain two divs with the same id. This is invalid HTML, and as a result, the underlying DOM API does not support it.
From the HTML standard:
id = name [CS] This attribute assigns a name to an element. This name must be unique in a document.
You can either assign different ids to each div and select them both using $('#id1, #id2)
. Or assign the same class to both elements (.cls
for example), and use $('.cls')
to select them both.
I know this has been answered, but here's mine just because I think case is an under-appreciated tool. (Maybe because people think it is slow, but it's at least as fast as an if, sometimes faster.)

rm -r $(python3 -c "import pkg; print(pkg.__path__[0] + '*' )")
rm -rf build
Obove work out for python3 and delete the package and its *.egg-info file
$otherController = new OtherController();
$otherController->methodFromOtherController($param1, $param2 ...);
But, doing this, you will have a problem: the other method returns something like response()->json($result), and is not it what you want.
To resolve this problem, define the first parameter of the other controller's method as:
public function methodFromOtherController(Request $request = null, ...
$otherController = new OtherController();
$otherController->methodFromOtherController(null, $param1, $param2 ...);
public function methodFromOtherController(Request $request = null, ...)
{
...
if (is_null($request)) {
return $result;
} else {
return response()->json($result);
}
}
Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.
So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.
Then it's very simple getting connected with it:
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')
stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()
Here's a little cmd script you can copy-n-paste into a file named something like where.cmd
:
@echo off
rem - search for the given file in the directories specified by the path, and display the first match
rem
rem The main ideas for this script were taken from Raymond Chen's blog:
rem
rem http://blogs.msdn.com/b/oldnewthing/archive/2005/01/20/357225.asp
rem
rem
rem - it'll be nice to at some point extend this so it won't stop on the first match. That'll
rem help diagnose situations with a conflict of some sort.
rem
setlocal
rem - search the current directory as well as those in the path
set PATHLIST=.;%PATH%
set EXTLIST=%PATHEXT%
if not "%EXTLIST%" == "" goto :extlist_ok
set EXTLIST=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
:extlist_ok
rem - first look for the file as given (not adding extensions)
for %%i in (%1) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i
rem - now look for the file adding extensions from the EXTLIST
for %%e in (%EXTLIST%) do @for %%i in (%1%%e) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i
You have write -webkit-appearance:none;
like this:
textarea:hover,
input:hover,
textarea:active,
input:active,
textarea:focus,
input:focus,
button:focus,
button:active,
button:hover,
label:focus,
.btn:active,
.btn.active
{
outline:0px !important;
-webkit-appearance:none;
box-shadow: none !important;
}
Initially define a function pointer array which takes a void and returns a void.
Assuming that your function is taking a void and returning a void.
typedef void (*func_ptr)(void);
Now you can use this to create function pointer variables of such functions.
Like below:
func_ptr array_of_fun_ptr[3];
Now store the address of your functions in the three variables.
array_of_fun_ptr[0]= &A;
array_of_fun_ptr[1]= &B;
array_of_fun_ptr[2]= &C;
Now you can call these functions using function pointers as below:
some_a=(*(array_of_fun_ptr[0]))();
some_b=(*(array_of_fun_ptr[1]))();
some_c=(*(array_of_fun_ptr[2]))();
If you don't have access to the v$ views (as suggested by Quassnoi) there are two alternatives
select utl_inaddr.get_host_name from dual
and
select sys_context('USERENV','SERVER_HOST') from dual
Personally I'd tend towards the last as it doesn't require any grants/privileges which makes it easier from stored procedures.
The easiest way for Spring Boot 2 without dependencies or code changes is just:
spring:
autoconfigure:
exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
Say A depends on B, then Spring will first instantiate A, then B, then set properties for B, then set B into A.
But what if B also depends on A?
My understanding is: Spring just found that A has been constructed (constructor executed), but not fully initialized (not all injections done), well, it thought, it's OK, it's tolerable that A is not fully initialized, just set this not-fully-initialized A instances into B for now. After B is fully initialized, it was set into A, and finally, A was fully initiated now.
In other words, it just expose A to B in advance.
For dependencies via constructor, Sprint just throw BeanCurrentlyInCreationException, to resolve this exception, set lazy-init to true for the bean which depends on others via constructor-arg way.
There many cases where script Manager may give problem like that. you Try This First add Script Manager in appropriate Placeholder or any place Holder which appears before the content in which Ajax Control is used.
We need to add ScriptManager while using any AJAX Control not only update Panel.
<asp:ScriptManager ID="ScriptManger1" runat="Server" />
If you are using Latest Ajax Control Toolkit (I am not sure about version 4.0 or 4.5) you need to use that Particular ToolkitScriptManager and not ScriptManager from default Ajax Extensions.
You can use only one ScriptManager or ToolKitScriptManager on page, If you have added it on Master Page you no need to add it again on Web Page.
The problem mentioned here may because of ContentPlaceHolder Please Check how many content place holders you have on your master page. Lets take an example if you have 2 content Placeholders "Head" and "ContentPlaceHolder1" on Master Page and ContentPlaceHolder1 is your Content Page.please check below code I added here my ScriptManager on Second Placeholder just below there is update panel.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder id="MainContent" runat="server">
<asp:ScriptManager ID="ScriptManger1" runat="Server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
Most of us make mistake while designing web form when we choose masterpage by default on web page there are equal number of placeholders as of MasterPage.
<%@ Page Title="" Language="C#" MasterPageFile="~/Master Pages/Home.master" AutoEventWireup="true" CodeFile="frmCompanyLogin.aspx.cs" Inherits="Authentication_frmCompanyLogin" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
</asp:Content>
We no need to remove any PlaceHolder it is guiding structure but you must have to add the web form Contents in Same PlaceHolder where you added your ScriptManager(on Master Page) or add Script Manager in appropriate Placeholder or any place Holder which appears before the content in which Ajax Control is used.
In XML values in text() nodes.
If we write this
<numbers>1,2,3</numbers>
in element "numbers
" will be one text() node with value "1,2,3".
Native way to get many text() nodes in element is insert nodes of other types in text.
Other available types is element or comment() node.
Split with element node:
<numbers>3<_/>2<_/>1</numbers>
Split with comment() node:
<numbers>3<!---->2<!---->1</numbers>
We can select this values by this XPath
//numbers/text()
Select value by index
//numbers/text()[3]
Will return text() node with value "1"
It's an attribute designed to help assistive technology (e.g. screen readers) attach a label to an otherwise anonymous HTML element.
So there's the <label>
element:
<label for="fmUserName">Your name</label>
<input id="fmUserName">
The <label>
explicitly tells the user to type their name into the input
box where id="fmUserName"
.
aria-label
does much the same thing, but it's for those cases where it isn't practical or desirable to have a label
on screen. Take the MDN example:
<button aria-label="Close" onclick="myDialog.close()">X</button>`
Most people would be able to infer visually that this button will close the dialog. A blind person using assistive technology might just hear "X" read aloud, which doesn't mean much without the visual clues. aria-label
explicitly tells them what the button will do.
//testing data types accurately in JavaScript (opposed to "typeof")
//from http://bonsaiden.github.com/JavaScript-Garden/
function is(type, obj) {
var clas = Object.prototype.toString.call(obj).slice(8, -1);
return obj !== undefined && obj !== null && clas === type;
}
//basic usage
is('String', 'test'); // true
is('Array', true); // false
Or adapt it to return an unknown type:
function realTypeOf(obj) {
return Object.prototype.toString.call(obj).slice(8, -1);
}
//usage
realTypeOf(999); // 'Number'

You can't (and shouldn't) block processing with a sleep function. However, you can use setTimeout
to kick off a function after a delay:
setTimeout(function(){alert("hi")}, 1000);
Depending on your needs, setInterval
might be useful, too.
For Xcode Version 8.2 (8C38), you can remove the projects completely (project name in Xcode, programs, data, etc.) one by one by doing the following: [Note: the instructions are not for just remove the project names from the Welcome Window]
Launch the Xocde and wait until the Welcome window is displayed. The projects will be shown on the right hand side (see below) Xcode Welcome Window
Right click the project you want to remove completely and a pop window [Show in Folder] jumps out; selec it to find out where is the project in the [Finder] (see below) Find the project folder
Right click the project folder in the Finder to find it’s path through [Get Info]; use path in the Info window to go to the parent folder, and go to there[Locate the project folder path] (see below)
Right click the Project Folder (e.g. DemoProject01) and Porject file (DemoProject01.xcodeproj) and select [Move to Trash] ; you will see that (a) the folder in finder is removed AND (b) the Project in the Xcode Welcome Window’s Project List is removed.
You'll want to:
What has your class covered along these lines so far?
sys.argv
is a list.
This list is created by your command line, it's a list of your command line arguments.
For example:
in your command line you input something like this,
python3.2 file.py something
sys.argv
will become a list ['file.py', 'something']
In this case sys.argv[1] = 'something'
