The constructor of PetStore
will call a constructor of Farm
; there's
no way you can prevent it. If you do nothing (as you've done), it will
call the default constructor (Farm()
); if you need to pass arguments,
you'll have to specify the base class in the initializer list:
PetStore::PetStore()
: Farm( neededArgument )
, idF( 0 )
{
}
(Similarly, the constructor of PetStore
will call the constructor of
nameF
. The constructor of a class always calls the constructors of
all of its base classes and all of its members.)
How about:
public static T As<T>(this object obj)
{
return JsonConvert.DeserializeObject<T>(JsonConvert.SerializeObject(obj));
}
Probably the author won't need my answer anymore. Still, for sake of completeness i feel other users might find it useful. The best and most simple solution is to use $(window).load()
inside the body of the returned function. (alternatively you can use document.ready
. It really depends if you need all the images or not).
Using $timeout
in my humble opinion is a very weak option and may fail in some cases.
Here is the complete code i'd use:
.directive('directiveExample', function(){
return {
restrict: 'A',
link: function($scope, $elem, attrs){
$(window).load(function() {
//...JS here...
});
}
}
});
1: Create a class WebMvcConfig and extend it as shown from the WebMvcConfiguration and override addCorsMappings method.
2: Most importantly don't forget to make it @Configuration annotation because it should be loaded with Main Spring class to allow Cross-Origin.
@Configuration
public class WebMvcCofig implements WebMvcConfigurer{
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/*")
.allowedOrigins("*")
.allowedMethods("*")
.allowedHeaders("*")
.allowCredentials(true);
}
}
Have you tried using?:
left:50%;
top:50%;
margin-left:-[half the width] /* As pointed out on the comments by Chetan Sastry */
Not sure if it'll work, but it's worth a try...
Minor edit: Added the margin-left part, as pointed out on the comments by Chetan...
Additionally to what Tomasz W wrote, by starting your application you could use settings:
-Dorg.apache.logging.log4j.simplelog.StatusLogger.level=TRACE
to get most of configuration problems.
For details see Log4j2 FAQ: How do I debug my configuration?
ng-pristine ($pristine)
Boolean True if the form/input has not been used yet (not modified by the user)
ng-dirty ($dirty)
Boolean True if the form/input has been used (modified by the user)
$setDirty(); Sets the form to a dirty state. This method can be called to add the 'ng-dirty' class and set the form to a dirty state (ng-dirty class). This method will propagate current state to parent forms.
$setPristine(); Sets the form to its pristine state. This method sets the form's $pristine state to true, the $dirty state to false, removes the ng-dirty class and adds the ng-pristine class. Additionally, it sets the $submitted state to false. This method will also propagate to all the controls contained in this form.
Setting a form back to a pristine state is often useful when we want to 'reuse' a form after saving or resetting it.
I have to guess here, but git is probably running its output into your $PAGER program, likely less
or more
. In either case, typing q should get you out.
You may well want to use JSON-P instead (see below). First a quick explanation.
The header you've mentioned is from the Cross Origin Resource Sharing standard. Beware that it is not supported by some browsers people actually use, and on other browsers (Microsoft's, sigh) it requires using a special object (XDomainRequest
) rather than the standard XMLHttpRequest
that jQuery uses. It also requires that you change server-side resources to explicitly allow the other origin (www.xxxx.com
).
To get the JSON data you're requesting, you basically have three options:
If possible, you can be maximally-compatible by correcting the location of the files you're loading so they have the same origin as the document you're loading them into. (I assume you must be loading them via Ajax, hence the Same Origin Policy issue showing up.)
Use JSON-P, which isn't subject to the SOP. jQuery has built-in support for it in its ajax
call (just set dataType
to "jsonp" and jQuery will do all the client-side work). This requires server side changes, but not very big ones; basically whatever you have that's generating the JSON response just looks for a query string parameter called "callback" and wraps the JSON in JavaScript code that would call that function. E.g., if your current JSON response is:
{"weather": "Dreary start but soon brightening into a fine summer day."}
Your script would look for the "callback" query string parameter (let's say that the parameter's value is "jsop123") and wraps that JSON in the syntax for a JavaScript function call:
jsonp123({"weather": "Dreary start but soon brightening into a fine summer day."});
That's it. JSON-P is very broadly compatible (because it works via JavaScript script
tags). JSON-P is only for GET
, though, not POST
(again because it works via script
tags).
Use CORS (the mechanism related to the header you quoted). Details in the specification linked above, but basically:
A. The browser will send your server a "preflight" message using the OPTIONS
HTTP verb (method). It will contain the various headers it would send with the GET
or POST
as well as the headers "Origin", "Access-Control-Request-Method" (e.g., GET
or POST
), and "Access-Control-Request-Headers" (the headers it wants to send).
B. Your PHP decides, based on that information, whether the request is okay and if so responds with the "Access-Control-Allow-Origin", "Access-Control-Allow-Methods", and "Access-Control-Allow-Headers" headers with the values it will allow. You don't send any body (page) with that response.
C. The browser will look at your response and see whether it's allowed to send you the actual GET
or POST
. If so, it will send that request, again with the "Origin" and various "Access-Control-Request-xyz" headers.
D. Your PHP examines those headers again to make sure they're still okay, and if so responds to the request.
In pseudo-code (I haven't done much PHP, so I'm not trying to do PHP syntax here):
// Find out what the request is asking for
corsOrigin = get_request_header("Origin")
corsMethod = get_request_header("Access-Control-Request-Method")
corsHeaders = get_request_header("Access-Control-Request-Headers")
if corsOrigin is null or "null" {
// Requests from a `file://` path seem to come through without an
// origin or with "null" (literally) as the origin.
// In my case, for testing, I wanted to allow those and so I output
// "*", but you may want to go another way.
corsOrigin = "*"
}
// Decide whether to accept that request with those headers
// If so:
// Respond with headers saying what's allowed (here we're just echoing what they
// asked for, except we may be using "*" [all] instead of the actual origin for
// the "Access-Control-Allow-Origin" one)
set_response_header("Access-Control-Allow-Origin", corsOrigin)
set_response_header("Access-Control-Allow-Methods", corsMethod)
set_response_header("Access-Control-Allow-Headers", corsHeaders)
if the HTTP request method is "OPTIONS" {
// Done, no body in response to OPTIONS
stop
}
// Process the GET or POST here; output the body of the response
Again stressing that this is pseudo-code.
If you are using other managed objects that are using unmanaged resources, it is not your responsibility to ensure those are finalized. Your responsibility is to call Dispose on those objects when Dispose is called on your object, and it stops there.
If your class doesn't use any scarce resources, I fail to see why you would make your class implement IDisposable. You should only do so if you're:
Yes, the code that uses your code must call the Dispose method of your object. And yes, the code that uses your object can use using
as you've shown.
(2 again?) It is likely that the WebClient uses either unmanaged resources, or other managed resources that implement IDisposable. The exact reason, however, is not important. What is important is that it implements IDisposable, and so it falls on you to act upon that knowledge by disposing of the object when you're done with it, even if it turns out WebClient uses no other resources at all.
I think you just have incorrect casing in the format string. According to the documentation this should work for you: MM/DD/YYYY
I have found that SpinWait works pretty well for this.
var task = Task.Run(()=>DoSomethingAsyncronous());
if(!SpinWait.SpinUntil(()=>task.IsComplete, TimeSpan.FromSeconds(30)))
{//Task didn't complete within 30 seconds, fail...
return false;
}
return true;
The above approach doesn't need to use .Result or .Wait(). It also lets you specify a timeout so that you're not stuck forever in case the task never completes.

One way to compare your local version before pushing it on the remote repo (kind of push in dry-run):
Use TortoiseGit:
Right click on the root folder project > TortoiseGit > Diff with previous version >
for Version 2 choose refs/remotes/origin/master
I like this to have enum in the dayNames. To reduce typing, we can do the following:
#define EP(x) [x] = #x /* ENUM PRINT */
const char* dayNames[] = { EP(Sunday), EP(Monday)};
Assume that the content of YourClass.py is:
class YourClass:
# ......
If you use:
from YourClassParentDir import YourClass # means YourClass.py
In this way, I got TypeError: 'module' object is not callable if you then tried to use YourClass()
.
But, if you use:
from YourClassParentDir.YourClass import YourClass # means Class YourClass
or use YourClass.YourClass()
, it works for me.

You need to import moment() the function and Moment the class separately in TS.
I found a note in the typescript docs here.
/*~ Note that ES6 modules cannot directly export callable functions
*~ This file should be imported using the CommonJS-style:
*~ import x = require('someLibrary');
So the code to import moment js into typescript actually looks like this:
import { Moment } from 'moment'
....
let moment = require('moment');
...
interface SomeTime {
aMoment: Moment,
}
...
fn() {
...
someTime.aMoment = moment(...);
...
}
If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE
Edit: On the model overview it's under Physical Schemata
Screenshot:
When dealing with the HTML DOM (ie. this
), the array selector [0]
must be used to retrieve the jQuery element from the Javascript array.
$(this)[0].getAttribute('src');

Here's the solution I used in Kotlin
private fun startTimer()
{
Log.d(TAG, ":startTimer: timeString = '$timeString'")
object : CountDownTimer(TASK_SWITCH_TIMER, 250)
{
override fun onTick(millisUntilFinished: Long)
{
val secondsUntilFinished : Long =
Math.ceil(millisUntilFinished.toDouble()/1000).toLong()
val timeString = "${TimeUnit.SECONDS.toMinutes(secondsUntilFinished)}:" +
"%02d".format(TimeUnit.SECONDS.toSeconds(secondsUntilFinished))
Log.d(TAG, ":startTimer::CountDownTimer:millisUntilFinished = $ttlseconds")
Log.d(TAG, ":startTimer::CountDownTimer:millisUntilFinished = $millisUntilFinished")
}
@SuppressLint("SetTextI18n")
override fun onFinish()
{
timerTxtVw.text = "0:00"
gameStartEndVisibility(true)
}
}.start()
}
>>> names = ['King', 'Queen', 'Joker']
>>> any(n in 'King and john' for n in names)
True
>>> all(n in 'King and Queen' for n in names)
False
It just reduce several line of code into one. You don't have to write lengthy code like:
for n in names:
if n in 'King and john':
print True
else:
print False
You need to do a couple of things to use the library:
Make sure that you have both the *.lib and the *.dll from the library you want to use. If you don't have the *.lib, skip #2
Put a reference to the *.lib in the project. Right click the project name in the Solution Explorer and then select Configuration Properties->Linker->Input and put the name of the lib in the Additional Dependencies property.
You have to make sure that VS can find the lib you just added so you have to go to the Tools menu and select Options... Then under Projects and Solutions select VC++ Directories,edit Library Directory option. From within here you can set the directory that contains your new lib by selecting the 'Library Files' in the 'Show Directories For:' drop down box. Just add the path to your lib file in the list of directories. If you dont have a lib you can omit this, but while your here you will also need to set the directory which contains your header files as well under the 'Include Files'. Do it the same way you added the lib.
After doing this you should be good to go and can use your library. If you dont have a lib file you can still use the dll by importing it yourself. During your applications startup you can explicitly load the dll by calling LoadLibrary (see: http://msdn.microsoft.com/en-us/library/ms684175(VS.85).aspx for more info)
Cheers!
EDIT
Remember to use #include < Foo.h > as opposed to #include "foo.h". The former searches the include path. The latter uses the local project files.
I am using JavaScript but some of the principles are common I am sure.
The code I am using is as follows:
var s = new webdriver.ActionSequence(d);
d.findElement(By.className('fc-time')).then(function(result){
s.mouseMove(result,l).click().perform();
});
the driver = d
.
The location = l
is simply {x:300,y:500)
- it is just an offset.
What I found during my testing was that I could not make it work without using the method to find an existing element first, using that at a basis from where to locate my click.
I suspect the figures in the locate are a bit more difficult to predict than I thought.
It is an old post but this response may help other newcomers like me.
Since Java 8 you can use the argument-less any
method and the type argument will get inferred by the compiler:
verify(bar).doStuff(any());
The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only arguments to methods where used for type parameter inference (most of the time).
In this case the parameter type of doStuff
will be the target type for any()
, and the return value type of any()
will get chosen to match that argument type.
This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.
This doesn't work with primitive types, unfortunately:
public interface IBar {
void doPrimitiveStuff(int i);
}
verify(bar).doPrimitiveStuff(any()); // Compiles but throws NullPointerException
verify(bar).doPrimitiveStuff(anyInt()); // This is what you have to do instead
The problem is that the compiler will infer Integer
as the return value type of any()
. Mockito will not be aware of this (due to type erasure) and return the default value for reference types, which is null
. The runtime will try to unbox the return value by calling the intValue
method on it before passing it to doStuff
, and the exception gets thrown.
Two Methods for Passing Multiple route params in Angular
Method-1
In app.module.ts
Set path as component2.
imports: [
RouterModule.forRoot(
[ {path: 'component2/:id1/:id2', component: MyComp2}])
]
Call router to naviagte to MyComp2 with multiple params id1 and id2.
export class MyComp1 {
onClick(){
this._router.navigate( ['component2', "id1","id2"]);
}
}
Method-2
In app.module.ts
Set path as component2.
imports: [
RouterModule.forRoot(
[ {path: 'component2', component: MyComp2}])
]
Call router to naviagte to MyComp2 with multiple params id1 and id2.
export class MyComp1 {
onClick(){
this._router.navigate( ['component2', {id1: "id1 Value", id2:
"id2 Value"}]);
}
}
One liner:
diff = lambda l1,l2: [x for x in l1 if x not in l2]
diff(A,B)
diff(B,A)
Or:
diff = lambda l1,l2: filter(lambda x: x not in l2, l1)
diff(A,B)
diff(B,A)
there's a bootstrap function to change the color of table header called thead-dark for dark background of table header and thead-light for light background of table header. Your code will look like this after using this function.
<table class="table">
<tr class="thead-danger">
<!-- here I used dark table headre -->
<th>
@Html.DisplayNameFor(model => model.name)
</th>
<th>
@Html.DisplayNameFor(model => model.checkBox1)
</th>
<th></th>
</tr>
'In Visual Basic
Dim FileName = "newfile.xml" ' The Name of file with its Extension Example A.txt or A.xml
Dim FilePath ="C:\MyFolderName" & "\" & FileName 'First Name of Directory and Then Name of Folder if it exists and then attach the name of file you want to search.
If System.IO.File.Exists(FilePath) Then
MsgBox("The file exists")
Else

If you don't want to chain (a huge number of) try-except clauses, you may try your codes in a loop and break upon 1st success.
Example with codes which can be put into functions:
for code in (
lambda: a / b,
lambda: a / (b + 1),
lambda: a / (b + 2),
):
try: print(code())
except Exception as ev: continue
break
else:
print("it failed: %s" % ev)
Example with arbitrary codes (statements) directly in the current scope:
for i in 2, 1, 0:
try:
if i == 2: print(a / b)
elif i == 1: print(a / (b + 1))
elif i == 0: print(a / (b + 2))
break
except Exception as ev:
if i:
continue
print("it failed: %s" % ev)
Let me clear two points here :
def example(a, b, c=None, r="w" , d=[], *ae, **ab):
(a,b) are positional parameter
(c=none) is optional parameter
(r="w") is keyword parameter
(d=[]) is list parameter
(*ae) is keyword-only
(**ab) is var-keyword parameter
def example(a, b, c=a,d=b):
argument is not defined when default values are saved,Python computes and saves default values when you define the function
c and d are not defined, does not exist, when this happens (it exists only when the function is executed)
"a,a=b" its not allowed in parameter.
Try with bufferFileWriter.append, it works with me.
FileWriter fileWriter;
try {
fileWriter = new FileWriter(file,true);
BufferedWriter bufferFileWriter = new BufferedWriter(fileWriter);
bufferFileWriter.append(obj.toJSONString());
bufferFileWriter.newLine();
bufferFileWriter.close();
} catch (IOException ex) {
Logger.getLogger(JsonTest.class.getName()).log(Level.SEVERE, null, ex);
}
You could try to use the following function
def tableIt(data):
for lin in data:
print("+---"*len(lin)+"+")
for inlin in lin:
print("|",str(inlin),"", end="")
print("|")
print("+---"*len(lin)+"+")
data = [[1,2,3,2,3],[1,2,3,2,3],[1,2,3,2,3],[1,2,3,2,3]]
tableIt(data)
Of course. The whole idea of abstract classes is that they can contain some behaviour or data which you require all sub-classes to contain. Think of the simple example of WheeledVehicle - it should have a numWheels member variable. You want all sub classes to have this variable. Remember that abstract classes are a very useful feature when developing APIs, as they can ensure that people who extend your API won't break it.
XML uses a tag structures for presenting items, like
<tag>item</tag>
,
so an XML document is a set of tags nested into each other.
And JSON syntax looks like a construction from Javascript language, with all stuff like lists and dictionaries:
{
'attrib' : 'value',
'array' : [1, 2, 3]
}
So if you use JSON it's really simple to use a JSON strings in many script languages, especially Javascript and Python.
I'm new in ASP.NET MVC. I faced the same problem, the following is my workable in my Erorr.vbhtml (it work if you only need to log the error using Elmah log)
@ModelType System.Web.Mvc.HandleErrorInfo
@Code
ViewData("Title") = "Error"
Dim item As HandleErrorInfo = CType(Model, HandleErrorInfo)
//To log error with Elmah
Elmah.ErrorLog.GetDefault(HttpContext.Current).Log(New Elmah.Error(Model.Exception, HttpContext.Current))
End Code
<h2>
Sorry, an error occurred while processing your request.<br />
@item.ActionName<br />
@item.ControllerName<br />
@item.Exception.Message
</h2>
It is simply!
You can define like this
define('GENERIC_DOMAIN',json_encode(array(
'gmail.com','gmail.co.in','yahoo.com'
)));
$domains = json_decode(GENERIC_DOMAIN);
var_dump($domains);
If you want to list all the files currently being tracked under the branch master
, you could use this command:
git ls-tree -r master --name-only
If you want a list of files that ever existed (i.e. including deleted files):
git log --pretty=format: --name-only --diff-filter=A | sort - | sed '/^$/d'
VSCode comes with in-built color themes which can be used to change the colors of the editor and the terminal.
ctrl+k+t
in windows/ubuntu or cmd+k+t
on mac.ctrl+shift+p
in windows/ubuntu or cmd+shift+p
on mac and type color
. Select preferences: color theme
from the options, to select your favourite color.category:themes
to install your favourite themes. (If you need to sort the themes by installs search category:themes @sort:installs
)Edit - for manually editing colors in terminal
VSCode team have removed customizing colors from user settings page. Currently using the themes is the only way to customize terminal colors in VSCode. For more information check out issue #6766
I had a nearly identical issue, turned out my JS file wasn't actually in the folder I was calling it from, and I had gone one folder too deep. I went up one directory, ran the file, it recognized it, happily ever after.
Alternatively, if you go one folder up, and it gives you the same error, but about a different module, take that same file in your parent folder and move it into the subfolder you were previously trying to run things from.
TL;DR- your file or its module(s) is not in the folder you think it is. Go up one level
I have used transform to correct the offset. It works great with round icons like the life ring.
<span class="fa fa-life-ring"></span>
.fa {
transform: translateY(-4%);
}
Apart from custom class or .Net 4.0 Tuples, since C# 7.0 there is a new feature called ValueTuple, which is a struct that can be used in this case. Instead of writing:
Tuple<string, int> t = new Tuple<string, int>("Hello", 4);
and access values through t.Item1
and t.Item2
, you can simply do it like that:
(string message, int count) = ("Hello", 4);
or even:
(var message, var count) = ("Hello", 4);
Primary key -> Any column or set of columns that can uniquely identify a record in the table is a primary key. (There can be only one Primary key in the table)
Candidate key -> Any column or set of columns that are candidate to become primary key are Candidate key. (There can be one or more candidate key(s) in the table, if there is only one candidate key, it can be chosen as Primary key)
About your command line:
root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save
You are already authenticated as root
so sudo
is redundant there.
You are missing the -j
or --jump
just before the ACCEPT
parameter (just tought that was a typo and you are inserting it correctly).
About yout question:
If you are inserting the iptables
rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.
If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:
check your vmachine network settings and:
if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.
if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.
if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.
Hope this helps.

For Xamarin.iOS (C#):
UIButton messagesButton = new UIButton(UIButtonType.Custom);
UIImage icon = UIImage.FromBundle("Images/icon.png");
messagesButton.SetImage(icon.ImageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), UIControlState.Normal);
messagesButton.TintColor = UIColor.White;
messagesButton.Frame = new RectangleF(0, 0, 25, 25);
Building on BrainCore's answer:
int index = 0;
str = "223232-1.jpg";
//Assuming we trust str isn't null
if (str.Contains('-') == "true")
{
int index = str.IndexOf('-');
}
if(index > 0) {
return str.Substring(0, index);
}
else {
return str;
}
When SET QUOTED_IDENTIFIER is OFF, literal strings in expressions can be delimited by single or double quotation marks.
If a literal string is delimited by double quotation marks, the string can contain embedded single quotation marks, such as apostrophes.
There is restriction on using --jars
: if you want to specify a directory for location of jar/xml
file, it doesn't allow directory expansions. This means if you need to specify absolute path for each jar.
If you specify --driver-class-path
and you are executing in yarn cluster mode, then driver class doesn't get updated. We can verify if class path is updated or not under spark ui or spark history server under tab environment.
Option which worked for me to pass jars which contain directory expansions and which worked in yarn cluster mode was --conf
option. It's better to pass driver and executor class paths as --conf
, which adds them to spark session object itself and those paths are reflected on Spark Configuration. But Please make sure to put jars on the same path across the cluster.

You want your change to sit on top of the current state of the remote branch. So probably you want to pull right before you commit yourself. After that, push your changes again.
"Dirty" local files are not an issue as long as there aren't any conflicts with the remote branch. If there are conflicts though, the merge will fail, so there is no risk or danger in pulling before committing local changes.
I think the concept of "notification sound" is someway wrong for Android UI.
The Android expected behaviour is to use the standard Notification to alert the user. If you play a notification sound without the status bar icon, you get the user confused ("what was that sound? there is no icon here, maybe I have hearing problems?").
How to set sound on a notification is, for example, here: Setting sound for notification
I think the best description about "Mercurial vs. Git" is:
Be careful here.
FlushDB deletes all keys in the current database while FlushALL deletes all keys in all databases on the current host.
If you're working from some network that requires you to use a proxy in your browser to connect to the internet (likely an office building), that might be it. I had the same issue and adding the proxy configs to the network settings solved it.
If you don't know the proxy url and port, talk to your network admin.
For me the answer didn't work too, but this work fine:
<link rel="shortcut icon" href="data:image/x-icon;," type="image/x-icon">
You have to specify what encoding the data is. Either in meta or in headers
header('Content-Type: text/plain; charset=utf-8');
A different approach could be
<script type="text/javascript">
function CheckData() {
//you may want to check something here and based on that wanna return true and false from the function.
if(MyStuffIsokay)
return true;//will cause form to postback to server.
else
return false;//will cause form Not to postback to server
}
</script>
@using (Html.BeginForm("SaveEmployee", "Employees", FormMethod.Post, new { id = "EmployeeDetailsForm" }))
{
.........
.........
.........
.........
<input type="submit" value= "Save Employee" onclick="return CheckData();"/>
}
if you wanna ng-model value, if you can write like this in the triggered event: $scope.searchText
If you use RecycleView, first you need more efford to setup. You need to give more time to setup simple Item onclick, border, touch event and other simple thing. But end product will be perfect.
So decision is yours. I suggest, if you design simple app like phonebook loading, where simple click of item is enough, you can implement listview. But if you design like social media home page with unlimited scrolling. Several different decoration between item, much control of individual item than use recycle view.
You can also use Url.Action for the path instead like so:
$.ajax({
url: "@Url.Action("Holiday", "Calendar", new { area = "", year= (val * 1) + 1 })",
type: "GET",
success: function (partialViewResult) {
$("#refTable").html(partialViewResult);
}
});
<a href="http://stackoverflow.com"
onclick="return confirm('Are you sure?');">My Link</a>
Disadvantage of deleting the deployed and .ova files is obvious i.e. you have to download the massive 200mb image again. A better choice is to :
That's it . Now you can use your already existing .ova file again to deploy image to new locatioin without any problem.
.button input,
.button a {
...
}
Do mean to check if $a is a non-empty string? So that it contains just any text? Then the following will work.
If $a contains a string, you can use the following:
if (!empty($a)) { // Means: if not empty
...
}
If you also need to confirm that $a is actually a string, use:
if (is_string($a) && !empty($a)) { // Means: if $a is a string and not empty
...
}
For others facing a similar problem to mine, where you know a particular object property cannot be null, you can use the non-null assertion operator (!) after the item in question. This was my code:
const naciStatus = dataToSend.naci?.statusNACI;
if (typeof naciStatus != "undefined") {
switch (naciStatus) {
case "AP":
dataToSend.naci.certificateStatus = "FALSE";
break;
case "AS":
case "WR":
dataToSend.naci.certificateStatus = "TRUE";
break;
default:
dataToSend.naci.certificateStatus = "";
}
}
And because dataToSend.naci
cannot be undefined in the switch statement, the code can be updated to include exclamation marks as follows:
const naciStatus = dataToSend.naci?.statusNACI;
if (typeof naciStatus != "undefined") {
switch (naciStatus) {
case "AP":
dataToSend.naci!.certificateStatus = "FALSE";
break;
case "AS":
case "WR":
dataToSend.naci!.certificateStatus = "TRUE";
break;
default:
dataToSend.naci!.certificateStatus = "";
}
}
For Android, Volley is a good place to get started. For all platforms, you might also want to check out ktor client or http4k which are both good libraries.
However, you can also use standard Java libraries like java.net.HttpURLConnection
which is part of the Java SDK:
fun sendGet() {
val url = URL("http://www.google.com/")
with(url.openConnection() as HttpURLConnection) {
requestMethod = "GET" // optional default is GET
println("\nSent 'GET' request to URL : $url; Response Code : $responseCode")
inputStream.bufferedReader().use {
it.lines().forEach { line ->
println(line)
}
}
}
}
Or simpler:
URL("https://google.com").readText()
If you already have a wheel file (.whl) on your pc, then just go with the following code:
cd ../user
pip install file.whl
If you want to download a file from web, and then install it, go with the following in command line:
pip install package_name
or, if you have the url:
pip install http//websiteurl.com/filename.whl
This will for sure install the required file.
Note: I had to type pip2 instead of pip while using Python 2.
I got this on Firefox (FF58). I fixed this with:
dom.moduleScripts.enabled

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj)
in your ModelForm.save
override, as ModelForm.save
later populates your m2m from self.cleaned_data['my_m2m']
which overwrites your changes. Instead call:
my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms
(It is fine to convert the incoming QuerySet to a list - the ManyToManyField
does that anyway.)

If you want to check if some string is present in another string, use something like String.contains
If you want to check if some pattern is present in a string, append and prepend the pattern with '.*'. The result will accept strings that contain the pattern.
Example: Suppose you have some regex a(b|c) that checks if a string matches ab
or ac
.*(a(b|c)).*
will check if a string contains a ab
or ac
.
A disadvantage of this method is that it will not give you the location of the match.
if your code is as follows then also this error occurs
private Image GetImage(byte[] byteArray)
{
using (var stream = new MemoryStream(byteArray))
{
return Image.FromStream(stream);
}
}
The correct one is
private Image GetImage(byte[] byteArray)
{
var stream = new MemoryStream(byteArray))
return Image.FromStream(stream);
}
This may be because we are returning from the using block
One can issue the SQL*Plus command SET TIMING ON
to get wall-clock times, but one can't take, for example, fetch time out of that trivially.
The AUTOTRACE setting, when used as SET AUTOTRACE TRACEONLY
will suppress output, but still perform all of the work to satisfy the query and send the results back to SQL*Plus, which will suppress it.
Lastly, one can trace the SQL*Plus session, and manually calculate the time spent waiting on events which are client waits, such as "SQL*Net message to client", "SQL*Net message from client".
In python, use and
instead of &&
like this:
#!/usr/bin/python
foo = True;
bar = True;
if foo and bar:
print "both are true";
This prints:
both are true
Try JadClipse.It will open all your .class file. Add library to your project and when you try to open any object declared in the lib file it will open just like your .java file.
In eclipse->help-> marketplace -> go to popular tab. There you can find plugins for the same.
Update: For those who are unable to find above plug-in, try downloading this: https://github.com/java-decompiler/jd-eclipse/releases/download/v1.0.0/jd-eclipse-site-1.0.0-RC2.zip
Then import it into Eclipse.
If you have issues importing above plug-in, refer: How to install plugin for Eclipse from .zip
Span does not have 'change' event by default. But you can add this event manually.
Listen to the change event of span.
$("#span1").on('change',function(){
//Do calculation and change value of other span2,span3 here
$("#span2").text('calculated value');
});
And wherever you change the text in span1. Trigger the change event manually.
$("#span1").text('test').trigger('change');
From MSDN -
CollectionViewSource.GetDefaultView(myGrid.ItemsSource).Refresh();
you can do like:
case text1:
case text4: {
//blah
break;
}
Since mysql_connect
has been deprecated, connect and query instead with mysqli:
$mysqli = new mysqli("hostname","username","password","database_name");
$sqlSelect="SELECT your_fieldname FROM your_table";
$result = $mysqli -> query ($sqlSelect);
And then, if you have more than one option list with the same values on the same page, put the values in an array:
while ($row = mysqli_fetch_array($result)) {
$rows[] = $row;
}
And then you can loop the array multiple times on the same page:
foreach ($rows as $row) {
print "<option value='" . $row['your_fieldname'] . "'>" . $row['your_fieldname'] . "</option>";
}

According to matplotlib documentation, The signature of the Axes
class grid()
method is as follows:
Axes.grid(b=None, which='major', axis='both', **kwargs)
Turn the axes grids on or off.
which
can be ‘major’ (default), ‘minor’, or ‘both’ to control whether major tick grids, minor tick grids, or both are affected.
axis
can be ‘both’ (default), ‘x’, or ‘y’ to control which set of gridlines are drawn.
So in order to show grid lines for both the x axis and y axis, we can use the the following code:
ax = plt.gca()
ax.grid(which='major', axis='both', linestyle='--')
This method gives us finer control over what to show for grid lines.
If you use Spring Boot, you can also enable a “debug” mode by starting your application with a --debug flag.
java -jar myapp.jar --debug
You can also specify debug=true in your application.properties.
When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate, and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages with DEBUG level.
Alternatively, you can enable a “trace” mode by starting your application with a --trace flag (or trace=true in your application.properties). Doing so enables trace logging for a selection of core loggers (embedded container, Hibernate schema generation, and the whole Spring portfolio).
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html
You could either get your strings by index (System.out.println(S.get(0));
) or iterate through it:
for (String s : S) {
System.out.println(s);
}
For other ways to iterate through a list (and their implications) see traditional for loop vs Iterator in Java.
Additionally:
I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.
int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
for(int i=0; i<=names.size()-1; ++i) {
if(names[i]==req_name){
cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
return 0;
}
else if(names[i]!=req_name && i==names.size()-1) {
cout<<"That name is not an element in this vector"<<'\n';
} else {
continue;
}
}
Make sure you image is a relative path such as:
@Url.Content("~/Content/images/myimage.png")
MVC4
<img src="~/Content/images/myimage.png" />
You could convert the byte[]
into a Base64
string
on the fly.
string base64String = Convert.ToBase64String(imageBytes);
<img src="@String.Format("data:image/png;base64,{0}", base64string)" />
for i in `seq 1 20`; do curl http://url; done
Or if you want to get timing information back, use ab
:
ab -n 20 http://url/
Based on all the answers on this thread, I wrote the following code and it worked for me.
If you have only some input/textarea tags which requires an onunload event to be checked, you can assign HTML5 data-attributes as data-onunload="true"
for eg.
<input type="text" data-onunload="true" />
<textarea data-onunload="true"></textarea>
and the Javascript (jQuery) can look like this :
$(document).ready(function(){
window.onbeforeunload = function(e) {
var returnFlag = false;
$('textarea, input').each(function(){
if($(this).attr('data-onunload') == 'true' && $(this).val() != '')
returnFlag = true;
});
if(returnFlag)
return "Sure you want to leave?";
};
});
For linking against libraries see Andre's answer.
For linker flags - the following 4 CMake variables:
CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS
can be easily manipulated for different configs (debug, release...) with the ucm_add_linker_flags macro of ucm
I have achieved this with following
Edit > Blank Operations > Remove Unnecessary Blank and EOL
I have used this:
DecimalFormat numFormat = new DecimalFormat("00000");
System.out.println("Code format: "+numFormat.format(123));
Result: 00123
I hope you find it useful!

The code you've already tried:
document.getElementById("gift-close").click();
...should work as long as the element actually exists in the DOM at the time you run it. Some possible ways to ensure that include:
onload
handler for the window. http://jsfiddle.net/LKNYg/So:
$(document).ready(function() {
document.getElementById("gift-close").click();
// OR
$("#gift-close")[0].click();
});
Using ES6 the javascript becomes a little cleaner
handleFiles(input) {
const file = input.target.files[0];
const reader = new FileReader();
reader.onload = (event) => {
const file = event.target.result;
const allLines = file.split(/\r\n|\n/);
// Reading line by line
allLines.forEach((line) => {
console.log(line);
});
};
reader.onerror = (event) => {
alert(event.target.error.name);
};
reader.readAsText(file);
}
For sdata
:
gsub(", ","",toString(sdata))
For a vector of integers:

BTW: When a Timeout happens, a timeout exception will be thrown
Thanks @Ole V.v for reviewing it: i have found some inbuilt library classes which does the same
int noOfMonths = 0;
org.joda.time.format.DateTimeFormatter formatter = DateTimeFormat
.forPattern("yyyy-MM-dd");
DateTime dt = formatter.parseDateTime(startDate);
DateTime endDate11 = new DateTime();
Months m = Months.monthsBetween(dt, endDate11);
noOfMonths = m.getMonths();
System.out.println(noOfMonths);
I would use it-str.begin() In this particular case std::distance and operator- are the same. But if container will change to something without random access, std::distance will increment first argument until it reach second, giving thus linear time and operator- will not compile. Personally I prefer the second behaviour - it's better to be notified when you algorithm from O(n) became O(n^2)...
final
indicates that the value cannot be changed once set. static
allows you to set the value, and that value will be the same for ALL instances of the class which utilize it. Also, you may access the value of a public static
string w/o having an instance of a class.
In the sense I think you intended, in ES5 or ES2015, no, not without some work on your part.
In ES2016, probably with object.values
.
Mind you Arrays in JavaScript are effectively a map from an integer to a value, and the values in JavaScript arrays can be enumerated directly.
['foo', 'bar'].forEach(v => console.log(v)); // foo bar
Also, in ES2015, you can make an object iterable by placing a function on a property with the name of Symbol.iterator
:
var obj = {
foo: '1',
bar: '2',
bam: '3',
bat: '4',
};
obj[Symbol.iterator] = iter.bind(null, obj);
function* iter(o) {
var keys = Object.keys(o);
for (var i=0; i<keys.length; i++) {
yield o[keys[i]];
}
}
for(var v of obj) { console.log(v); } // '1', '2', '3', '4'
Also, per other answers, there are other built-ins that provide the functionality you want, like Map
(but not WeakMap
because it is not iterable) and Set
for example (but these are not present in all browsers yet).
The important thing I understood is: While initializing an array(in any dimension) We should give a default value to all the positions of array. Then only initialization completes. After that, we can change or receive new values to any position of the array. The below code worked for me perfectly
N=7
F=2
#INITIALIZATION of 7 x 2 array with deafult value as 0
ar=[[0]*F for x in range(N)]
#RECEIVING NEW VALUES TO THE INITIALIZED ARRAY
for i in range(N):
for j in range(F):
ar[i][j]=int(input())
print(ar)
Wrong syntax. You can't compare a Boolean to a string like "false" or "true". In your case, just test it's inverse:
if(!ValidateForm()) { ...
You could test against the constant false, but it's rather ugly and generally frowned upon:
if(ValidateForm() == false) { ...
More "gentle" mode from the documentation:
docker run -dit --restart unless-stopped <image_name>
Another aproach is:
let result = { ...item, location : { ...response } }
But Object spread isn't yet standardized.

E.g if you have submit button on form ,inorder to stop its propogation simply write event.preventDefault(); in the function which is called upon clicking submit button or enter button.

Delete all app files from Phone
To automate the deletion of an app on your phone you can use the steps below. It can be very useful to delete your app and app data on a quick and clean way.
Make a textfile with this code and save it as Uninstall.sh. Go to the folder (where you've put it) of this script in the terminal and do: sh Uninstall.sh YOURNAMESPACE
Now your namespacefolder (including saved appfiles and database) will be deleted.
echo "Going to platform tools $HOME/Library/Android/sdk/platform-tools"
cd $HOME/Library/Android/sdk/platform-tools
echo "uninstalling app with packagae name $1"
./adb uninstall $1
Delete all app files from pc
Make a textfile with this code and save it as DeleteBinObj.sh.
find . -iname "bin" -o -iname "obj" | xargs rm -rf
Go to the folder of your project where you place this script and do in the terminal: sh DeleteBinObj.sh
Out of curiosity, I found a box with a GNU version of sed
(v4.1.5) and tested the (uncached) performance of two approaches suggested so far, using an 11M line text file:

This is the Linux I was working with:
$ uname -a
Linux hostname 2.6.18-128.1.1.el5 #1 SMP Mon Jan 26 13:58:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
For this test, at least, it looks like sed
is slower than the tail
approach (27 sec vs ~14 sec).
I assume you are using logback (from the configuration file).
From logback manual, I see
Logger rootLogger = LoggerFactory.getLogger(org.slf4j.Logger.ROOT_LOGGER_NAME);
Perhaps this can help you change the value?
There are two ways(actually there are more) that you could do this.
1. using lxml
pip install lxml
from lxml import etree, objectify
from lxml.etree import XMLSyntaxError
def xml_validator(some_xml_string, xsd_file='/path/to/my_schema_file.xsd'):
try:
schema = etree.XMLSchema(file=xsd_file)
parser = objectify.makeparser(schema=schema)
objectify.fromstring(some_xml_string, parser)
print "YEAH!, my xml file has validated"
except XMLSyntaxError:
#handle exception here
print "Oh NO!, my xml file does not validate"
pass
xml_file = open('my_xml_file.xml', 'r')
xml_string = xml_file.read()
xml_file.close()
xml_validator(xml_string, '/path/to/my_schema_file.xsd')
>> xmllint --format --pretty 1 --load-trace --debug --schema /path/to/my_schema_file.xsd /path/to/my_xml_file.xml
I was also getting this error, I deleted dlls from my debug folder and when I started a new instance for debug I got this error. For me the issue was due to the the build setting, Release was selected in the build type, I just changed it to debug and then application was working fine
Just to offer an update to the answer for people with API min 19, per the docs:
On Android 4.4 (API level 19) and higher, you have the additional option of using the ACTION_OPEN_DOCUMENT intent, which displays a system-controlled picker UI controlled that allows the user to browse all files that other apps have made available. From this single UI, the user can pick a file from any of the supported apps.
On Android 5.0 (API level 21) and higher, you can also use the ACTION_OPEN_DOCUMENT_TREE intent, which allows the user to choose a directory for a client app to access.
Open files using storage access framework - Android Docs
val intent = Intent(Intent.ACTION_OPEN_DOCUMENT)
intent.type = "image/*"
startActivityForResult(intent, PICK_IMAGE_REQUEST_CODE)
Android throws an exception if you fail to pass the height or width of a view. Instead of creating a new LayoutParams object, use the original one, so that all other set parameters are kept. Note that the type of LayoutParams returned by getLayoutParams is that of the parent layout, not the view you are resizing.
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) someLayout.getLayoutParams();
params.height = 130;
someLayout.setLayoutParams(params);
Expanding on @gecco 's answer, the following is an example that'll show you the difference:
def foo(**kwargs):
for entry in kwargs.items():
print("Key: {}, value: {}".format(entry[0], entry[1]))
# call using normal keys:
foo(a=1, b=2, c=3)
# call using an unpacked dictionary:
foo(**{"a": 1, "b":2, "c":3})
# call using a dictionary fails because the function will think you are
# giving it a positional argument
foo({"a": 1, "b": 2, "c": 3})
# this yields the same error as any other positional argument
foo(3)
foo("string")
Here you can see how unpacking a dictionary works, and why sending an actual dictionary fails
.ico
, or is it just named ".ico"?The absolutely easiest way to have a favicon is to place an icon called "favicon.ico" in the root folder. That just works everywhere, no code needed at all.
If you must have it in a subdirectory, use:
<link rel="shortcut icon" href="/img/favicon.ico" />
Note the /
before img
to ensure it is anchored to the root folder.
Go to Project | Properties and then Assembly Information and then Assembly Version and put an * in the last or the second-to-last box (you can't auto-increment the Major or Minor components).
JNDI in layman's terms is basically an Interface for being able to get instances of internal/External resources such as
javax.sql.DataSource,
javax.jms.Connection-Factory,
javax.jms.QueueConnectionFactory,
javax.jms.TopicConnectionFactory,
javax.mail.Session, java.net.URL,
javax.resource.cci.ConnectionFactory,
or any other type defined by a JCA resource adapter. It provides a syntax in being able to create access whether they are internal or external. i.e (comp/env in this instance means where component/environment, there are lots of other syntax):
jndiContext.lookup("java:comp/env/persistence/customerDB");
I'm not fine with solutions that iterates over a collection and inside the loop manipulating the content of even that collection. This can result in unexpected behaviour.
See also here: https://stackoverflow.com/a/2304578/655224 and in a comment the given link http://php.net/manual/en/control-structures.foreach.php#88578
So, when using foreach
if seems to be OK but IMHO the much more readable and simple solution is to filter your collection to a new one.
/**
* Filter all `selected` items
*
* @link https://laravel.com/docs/7.x/collections#method-filter
*/
$selected = $collection->filter(function($value, $key) {
return $value->selected;
})->toArray();
The length function will do it. See http://www.techonthenet.com/oracle/functions/length.php
One more related question, since it took me forever to find the answer:
How to make the legend background blank (i.e. transparent, not white):
legend = plt.legend()
legend.get_frame().set_facecolor('none')
Warning, you want 'none'
(the string). None
means the default color instead.
User u = UserCollection.Single(u => u.Id == 1);
u.FirstName = "Bob"
I know the question is Old and already answered but this can also be a solution

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:
sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})
This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:
axs.set_ylabel('mylabel',size=6)
you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.
def set_pubfig:
sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})
Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.
Note: If you specify these numbers, specifying font_scale
in sns.set_context
is ignored for all specified font elements, even if you set it.
Try below piece of code.
this.dataGridView1.RefreshEdit();
Extending on what Martin said, recording the install output and a little bash scripting does the trick quite nicely. Here's what I do...
for i in $(less install.record);
sudo rm $i;
done;
And presto. Uninstalled.
U can use direct
$"(.ddlClassName").Html("<option selected=\"selected\" value=\"1\">1</option><option value=\"2\">2</option>")
-> Here u can use direct string
Instead of %matplotlib inline,it is not a python script so we can write like this it will work from IPython import get_ipython get_ipython().run_line_magic('matplotlib', 'inline')
You can use the simple program StarUML. The trial version is unlimited and can do almost anything.
Onced installed you can use it to generate great number of uml digrams just by pasting the source code. Class diagram is just one type of it. (It understands not only Java language but C#, C++ and other)
P.S. The program is great for drawing architectural diagrams before you start to code the program.
IMHO, using list()
and dict()
makes your Python look like C. Ugh.
Another (simpler) Linux solution:
rm -r `find /path/to/foo -name .svn`
You can use ElementRef as shown below,
DEMO : https://plnkr.co/edit/XZwXEh9PZEEVJpe0BlYq?p=preview check browser's console.
import { Directive,Input,Outpu,ElementRef,Renderer} from '@angular/core';
@Directive({
selector:"[move]",
host:{
'(click)':"show()"
}
})
export class GetEleDirective{
constructor(private el:ElementRef){
}
show(){
console.log(this.el.nativeElement);
console.log('height---' + this.el.nativeElement.offsetHeight); //<<<===here
console.log('width---' + this.el.nativeElement.offsetWidth); //<<<===here
}
}
Same way you can use it within component itself wherever you need it.
There is no "isContentViewSet" method. You may put some dummy requestWindowFeature call into try/catch block before setContentView like this:
try { requestWindowFeature(Window.FEATURE_CONTEXT_MENU); setContentView(...) } catch (AndroidRuntimeException e) { // do smth or nothing }
If content view was already set, requestWindowFeature will throw an exception.
A little more readable :)
public static <T> ArrayList<T> reverse(ArrayList<T> list) {
int length = list.size();
ArrayList<T> result = new ArrayList<T>(length);
for (int i = length - 1; i >= 0; i--) {
result.add(list.get(i));
}
return result;
}
I went ahead and implemented greybeard suggestion in the comments. Mostly because I needed a highly efficient mission critical version of this code.
This should be the most efficient way to do this, with time complexity of O(log(n)*log(i)) rather than O(n). And worst case time complexity of O(n). If your arrays are clumpy and have long strings of values together, this will dwarf any other way to do it, otherwise it'll just be better than them.
It has two read values at the ends of the merging array and the write value within the results array. After finding out which is end value is less, it does a gallop search into that array. 1, 2, 4, 8, 16, 32, etc. When it finds the range where the the other array's read value is bigger. It binary searches into that range (cuts the range in half, search the correct half, repeat until single value). Then it array copies those values into the write position. Keeping in mind that the copy is, by necessity, moved such that it cannot overwrite the same values from the either reading array (which means the write array and read array can be the same). It then performs the same operation for the other array which is now known to be less than the new read value of the other array.
static public int gallopSearch(int current, int[] array, int v) {
int d = 1;
int seek = current - d;
int prevIteration = seek;
while (seek > 0) {
if (Integer.compare(array[seek], v) <= 0) {
break;
}
prevIteration = seek;
d <<= 1;
seek = current - d;
if (seek < 0) {
seek = 0;
}
}
if (prevIteration != seek) {
seek = binarySearch(array, seek, prevIteration, v);
seek = seek >= 0 ? seek : ~seek;
}
return seek;
}
static public int binarySearch(int[] list, int fromIndex, int toIndex, int v) {
int low = fromIndex;
int high = toIndex - 1;
while (low <= high) {
int mid = (low + high) >>> 1;
int midVal = list[mid];
int cmp = Integer.compare(midVal, v);
if (cmp < 0) {
low = mid + 1;
} else if (cmp > 0) {
high = mid - 1;
} else {
return mid;// key found
}
}
return -(low + 1);// key not found.
}
static public int[] sortedArrayMerge(int[] a, int[] b) {
return sortedArrayMerge(null, a, a.length, b, b.length);
}
static public int[] sortedArrayMerge(int[] results, int[] a, int aRead, int b[], int bRead) {
int write = aRead + bRead, length, gallopPos;
if ((results == null) || (results.length < write)) {
results = new int[write];
}
if (aRead > 0 && bRead > 0) {
int c = Integer.compare(a[aRead - 1], b[bRead - 1]);
while (aRead > 0 && bRead > 0) {
switch (c) {
default:
gallopPos = gallopSearch(aRead, a, b[bRead-1]);
length = (aRead - gallopPos);
write -= length;
aRead = gallopPos;
System.arraycopy(a, gallopPos--, results, write, length);
c = -1;
break;
case -1:
gallopPos = gallopSearch(bRead, b, a[aRead-1]);
length = (bRead - gallopPos);
write -= length;
bRead = gallopPos;
System.arraycopy(b, gallopPos--, results, write, length);
c = 1;
break;
}
}
}
if (bRead > 0) {
if (b != results) {
System.arraycopy(b, 0, results, 0, bRead);
}
} else if (aRead > 0) {
if (a != results) {
System.arraycopy(a, 0, results, 0, aRead);
}
}
return results;
}
This should be the most efficient way to do it.
Some answers had a duplicate remove ability. That'll require an O(n) algorithm because you must actually compare each item. So here's a stand-alone for that, to be applied after the fact. You can't gallop through multiple entries all the way through if you need to look at all of them, though you could gallop through the duplicates, if you had a lot of them.
static public int removeDuplicates(int[] list, int size) {
int write = 1;
for (int read = 1; read < size; read++) {
if (list[read] == list[read - 1]) {
continue;
}
list[write++] = list[read];
}
return write;
}
Update: Previous answer, not horrible code but clearly inferior to the above.
Another needless hyper-optimization. It not only invokes arraycopy for the end bits, but also for the beginning. Processing any introductory non-overlap in O(log(n)) by a binarySearch into the data. O(log(n) + n) is O(n) and in some cases the effect will be pretty pronounced especially things like where there is no overlap between the merging arrays at all.
private static int binarySearch(int[] array, int low, int high, int v) {
high = high - 1;
while (low <= high) {
int mid = (low + high) >>> 1;
int midVal = array[mid];
if (midVal > v)
low = mid + 1;
else if (midVal < v)
high = mid - 1;
else
return mid; // key found
}
return low;//traditionally, -(low + 1); // key not found.
}
private static int[] sortedArrayMerge(int a[], int b[]) {
int result[] = new int[a.length + b.length];
int k, i = 0, j = 0;
if (a[0] > b[0]) {
k = i = binarySearch(b, 0, b.length, a[0]);
System.arraycopy(b, 0, result, 0, i);
} else {
k = j = binarySearch(a, 0, a.length, b[0]);
System.arraycopy(a, 0, result, 0, j);
}
while (i < a.length && j < b.length) {
result[k++] = (a[i] < b[j]) ? a[i++] : b[j++];
}
if (j < b.length) {
System.arraycopy(b, j, result, k, (b.length - j));
} else {
System.arraycopy(a, i, result, k, (a.length - i));
}
return result;
}
Yes, you're looking for the ReDim
statement, which dynamically allocates the required amount of space in the array.
The following statement
Dim MyArray()
declares an array without dimensions, so the compiler doesn't know how big it is and can't store anything inside of it.
But you can use the ReDim
statement to resize the array:
ReDim MyArray(0 To 3)
And if you need to resize the array while preserving its contents, you can use the Preserve
keyword along with the ReDim
statement:
ReDim Preserve MyArray(0 To 3)
But do note that both ReDim
and particularly ReDim Preserve
have a heavy performance cost. Try to avoid doing this over and over in a loop if at all possible; your users will thank you.
However, in the simple example shown in your question (if it's not just a throwaway sample), you don't need ReDim
at all. Just declare the array with explicit dimensions:
Dim MyArray(0 To 3)
I had a similar issue today where only the prompt was available after installation. Finally solved this by un-installing my regular python installation and then install anaconda(anaconda 3 v5.2.0, with python 3.6).
document.getElementById("address_box").value =
(title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4);
Tieme put a lot of effort into his excellent answer, but I think the core of the OP's question is how these technologies relate to PHP rather than how each technology works.
PHP is the most used language in web development besides the obvious client side HTML, CSS, and Javascript. Yet PHP has 2 major issues when it comes to real-time applications:
libphp5.so
on Linux, php5ts.dll
on Windows, etc) as if it still a CGI processing a GET/POST request. It still executes code as if it just has to build a "page" and then end its life cycle. As a result, it has very little support for multi-thread or event-driven programming (within PHP userspace), making it currently unpractical for real-time, multi-user applications.Note that PHP does have extensions to provide event loops (such as libevent
) and threads (such as pthreads
) in PHP userspace, but very, very, few of the applications use these.
PHP 7 will be a great step to fix these issues as well, and seems very promising as a platform for real-time applications.
Check all the references carefully
For me cleaning entire solution by deleting manually, updating (removing and adding) references again with version in sync with target machine and then building with with Copy Local > False for GAC assemblies solves the problem.
Already some great answers to this question, however here is a nice snippet that I use regularly to drop rows if they have non-numeric values on some columns:
# Eliminate invalid data from dataframe (see Example below for more context)
num_df = (df.drop(data_columns, axis=1)
.join(df[data_columns].apply(pd.to_numeric, errors='coerce')))
num_df = num_df[num_df[data_columns].notnull().all(axis=1)]
The way this works is we first drop
all the data_columns
from the df
, and then use a join
to put them back in after passing them through pd.to_numeric
(with option 'coerce'
, such that all non-numeric entries are converted to NaN
). The result is saved to num_df
.
On the second line we use a filter that keeps only rows where all values are not null.
Note that pd.to_numeric
is coercing to NaN
everything that cannot be converted to a numeric value, so strings that represent numeric values will not be removed. For example '1.25'
will be recognized as the numeric value 1.25
.
Disclaimer: pd.to_numeric
was introduced in pandas version 0.17.0
Example:
In [1]: import pandas as pd
In [2]: df = pd.DataFrame({"item": ["a", "b", "c", "d", "e"],
...: "a": [1,2,3,"bad",5],
...: "b":[0.1,0.2,0.3,0.4,0.5]})
In [3]: df
Out[3]:
a b item
0 1 0.1 a
1 2 0.2 b
2 3 0.3 c
3 bad 0.4 d
4 5 0.5 e
In [4]: data_columns = ['a', 'b']
In [5]: num_df = (df
...: .drop(data_columns, axis=1)
...: .join(df[data_columns].apply(pd.to_numeric, errors='coerce')))
In [6]: num_df
Out[6]:
item a b
0 a 1 0.1
1 b 2 0.2
2 c 3 0.3
3 d NaN 0.4
4 e 5 0.5
In [7]: num_df[num_df[data_columns].notnull().all(axis=1)]
Out[7]:
item a b
0 a 1 0.1
1 b 2 0.2
2 c 3 0.3
4 e 5 0.5
In a batch file I usually create a file in the temp directory and append output from a program, then I call it with a variable-name to set that variable. Like this:
:: Create a set_var.cmd file containing: set %1=
set /p="set %%1="<nul>"%temp%\set_var.cmd"
:: Append output from a command
ipconfig | find "IPv4" >> "%temp%\set_var.cmd"
call "%temp%\set_var.cmd" IPAddress
echo %IPAddress%
SELECT *
FROM Customer
WHERE (I.IsClose=@ISClose OR @ISClose is NULL)
AND (C.FirstName like '%'+@ClientName+'%' or @ClientName is NULL )
AND (isnull(@Value,1) <> 2
OR I.RecurringCharge = @Total
OR @Total is NULL )
AND (isnull(@Value,2) <> 3
OR I.RecurringCharge like '%'+cast(@Total as varchar(50))+'%'
OR @Total is NULL )
Basically, your condition was
if (@Value=2)
TEST FOR => (I.RecurringCharge=@Total or @Total is NULL )
flipped around,
AND (isnull(@Value,1) <> 2 -- A
OR I.RecurringCharge = @Total -- B
OR @Total is NULL ) -- C
When (A) is true, i.e. @Value is not 2, [A or B or C] will become TRUE regardless of B and C results. B and C are in reality only checked when @Value = 2
, which is the original intention.
The below query will work perfect for both even or odd number of rows. In the subquery, we are finding the value(s) which has same number of rows before and after it. In case of odd rows the having clause will evaluate to 0 (same number of rows before and after cancels out the sign).
Similarly, for even rows the having clause evaluates to 1 for two rows (the center 2 rows) because they will (collectively) have same number of rows before and after.
In the outer query, we will avg out either the single value (in case of odd rows) or (2 values in case of even rows).
select avg(val) as median
from
(
select d1.val
from data d1 cross join data d2
group by d1.val
having abs(sum(sign(d1.val-d2.val))) in (0,1)
) sub
Note: In case your table has duplicate values, the above having clause should be changed to the below condition. In this case, there could be values outside of the original possibilities of 0,1. The below condition will make this condition dynamic and work in case of duplicates too.
having sum(case when d1.val=d2.val then 1 else 0 end)>=
abs(sum(sign(d1.val-d2.val)))
I came across System.Runtime.InteropServices.COMException
while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM
Methods. I ran Visual Studio as Administrator and the exception was gone.
For Git Bash for Windows (in ConEmu), the following works for me (for Docker Windows containers):
docker run --rm -it -v `pwd -W`:c:/api microsoft/dotnet:2-runtime
Note the backticks/backquotes around pwd -W
!
With all other variations of PWD I've tried I've received: "Error response from daemon: invalid volume specification: ..."
Update: The above was for Docker Windows containers, for Linux containers use:
docker run --rm -it -v `pwd -W`:/api -p 8080:80 microsoft/aspnetcore:2

Of course, change the GMAIL_USERNAME and GMAIL_PASSWORD values to your particular user and password.
Perhaps the best two browser techs for this are Canvas, with Flash as a back up.
We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.
With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.
This query fetches a list of all columns in a database without having to specify a table name. It returns a list of only column names:
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_schema = 'db_name'
However, when I ran this query in phpmyadmin, it displayed a series of errors. Nonetheless, it worked. So use it with caution.
.NET languages can be as fast as C++ code, or even faster, but C++ code will have a more constant throughput as the .NET runtime has to pause for GC, even if it's very clever about its pauses.
So if you have some code that has to consistently run fast without any pause, .NET will introduce latency at some point, even if you are very careful with the runtime GC.
Yes. Try:
class USBDevice : GenericDevice, IOurDevice
Note: The base class should come before the list of interface names.
Of course, you'll still need to implement all the members that the interfaces define. However, if the base class contains a member that matches an interface member, the base class member can work as the implementation of the interface member and you are not required to manually implement it again.
You can try with this code (Same case)
chaine1 + chaine2;
I suggest you also (I prefer this) the string.concat method
stringByReplacingOccurrencesOfString will replace all white space with in the string non only the starting and end
Use
[YourString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]
Extrapolating from Rolando's answer above, it is these that are blocking your query:
---TRANSACTION 0 620783788, not started, process no 29956, OS thread id 1196472640
MySQL thread id 5341773, query id 189708353 10.64.89.143 viget
If you need to execute your query and can not wait for the others to run, kill them off using the MySQL thread id:
kill 5341773 <replace with your thread id>
(from within mysql, not the shell, obviously)
You have to find the thread IDs from the:
show engine innodb status\G
command, and figure out which one is the one that is blocking the database.
Try the following code.
File file = new File(path); // path = your file path
lastSlash = file.toString().lastIndexOf('/');
if (lastSlash >= 0)
{
fileName = url.toString().substring(lastSlash + 1);
}
if (fileName.endsWith("pdf"))
{
mimeType = "application/pdf";
}
else
{
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension
(MimeTypeMap.getFileExtensionFromUrl(path));
}
Uri uri_path = Uri.fromFile(file);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.putExtra(PATH, path);
intent.putExtra(MIMETYPE, mimeType);
intent.setType(mimeType);
intent.setDataAndType(uri_path, mimeType);
startActivity(intent);
In order to download a file to Download or Music Folder In SDCard
File downlodDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);// or DIRECTORY_PICTURES
And dont forget to add these permission in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.min.js"defer</script>
Add Defer to the end of your Script tag, it worked for me (;
Everything needs to be loaded in the correct order (:
CSS (or jQuery, for that matter) can't animate between display: none;
and display: block;
. Worse yet: it can't animate between height: 0
and height: auto
. So you need to hard code the height (if you can't hard code the values then you need to use javascript, but this is an entirely different question);
#main-image{
height: 0;
overflow: hidden;
background: red;
-prefix-animation: slide 1s ease 3.5s forwards;
}
@-prefix-keyframes slide {
from {height: 0;}
to {height: 300px;}
}
You mention that you're using Animate.css, which I'm not familiar with, so this is a vanilla CSS.
You can see a demo here: http://jsfiddle.net/duopixel/qD5XX/

Why Lists Can't Be Dictionary Keys
Newcomers to Python often wonder why, while the language includes both a tuple and a list type, tuples are usable as a dictionary keys, while lists are not. This was a deliberate design decision, and can best be explained by first understanding how Python dictionaries work.
Source & more info: http://wiki.python.org/moin/DictionaryKeys
And this is less
@primarycolor: #ffffff;
@width: 800px;

You can use the following script if you don't wish to use Wizard;
RESTORE DATABASE myDB
FROM DISK = N'C:\BackupDB.bak'
WITH REPLACE,RECOVERY,
MOVE N'HRNET' TO N'C:\MSSQL\Data\myDB.mdf',
MOVE N'HRNET_LOG' TO N'C:\MSSQL\Data\myDB.ldf'
You can do:
var buf = Buffer.from(bufStr, 'utf8');
But this is a bit silly, so another suggestion would be to copy the minimal amount of code out of the called function to allow yourself access to the original buffer. This might be quite easy or fairly difficult depending on the details of that library.
This appears to be an (undocumented) "GNU extension": [correction: I finally found a mention in the docs. See below.]
The following command uses the -dM
option to print all preprocessor defines; since the input "file" is empty, it shows exactly the predefined macros. It was run with gcc-4.7.3 on a standard ubuntu install. You can see that the preprocessor is standard-aware. In total, there 243 macros with -std=gnu99
and 240 with -std=c99
; I filtered the output for relevance.
$ cpp --std=c89 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
$ cpp --std=gnu89 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1
$ cpp --std=c99 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
$ cpp --std=gnu99 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1
The "gnu standard" versions also #define unix
. (Using c11
and gnu11
produces the same results.)
I suppose they had their reasons, but it seems to me to make the default installation of gcc (which compiles C code with -std=gnu89
unless otherwise specified) non-conformant, and -- as in this question -- surprising. Polluting the global namespace with macros whose names don't begin with an underscore is not permitted in a conformant implementation. (6.8.10p2: "Any other predefined macro names shall begin with a leading underscore followed by an uppercase letter or a second
underscore," but, as mentioned in Appendix J.5 (portability issues), such names are often predefined.)
When I originally wrote this answer, I wasn't able to find any documentation in gcc about this issue, but I did finally discover it, not in C implementation-defined behaviour nor in C extensions but in the cpp
manual section 3.7.3, where it notes that:
We are slowly phasing out all predefined macros which are outside the reserved namespace. You should never use them in new programs…
I've used this method (reported here )
export class AppComponent {
constructor() {
if(document.getElementById("testScript"))
document.getElementById("testScript").remove();
var testScript = document.createElement("script");
testScript.setAttribute("id", "testScript");
testScript.setAttribute("src", "assets/js/test.js");
document.body.appendChild(testScript);
}
}
it worked for me since I wanted to execute a javascript file AFTER THE COMPONENT RENDERED.
You can use CSS white-space Property
to achieve this.
white-space: nowrap
add these in php file where your ajax url call
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Credentials: true ");
header("Access-Control-Allow-Methods: OPTIONS, GET, POST");
header("Access-Control-Allow-Headers: Content-Type, Depth, User-Agent, X-File-Size, X-Requested-With, If-Modified-Since, X-File-Name, Cache-Control");
For MAC and LINUX use the following procedure:
Add the directory where composer.phar is located to you PATH:
export PATH=$PATH:/yourdirectory
and then rename composer.phar to composer:
mv composer.phar composer
I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).
A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.
Do like this:
create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;
$ git submodule status --recursive
Is also a life saver in this situation. You can use it and gitk --all
to keep track of your sha1's and verify your sub-modules are pointing at what you think they are.
Use
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
public class test {
public static void main(String[] args){
try {
File fileDir = new File("PATH_TO_FILE");
BufferedReader in = new BufferedReader(
new InputStreamReader(new FileInputStream(fileDir), "UTF-8"));
String str;
while ((str = in.readLine()) != null) {
System.out.println(str);
}
in.close();
}
catch (UnsupportedEncodingException e)
{
System.out.println(e.getMessage());
}
catch (IOException e)
{
System.out.println(e.getMessage());
}
catch (Exception e)
{
System.out.println(e.getMessage());
}
}
}
You need to put UTF-8 in quotes
An alternative package that you can use is readxl
. This package don't require external dependencies.
DirectoryInfo does the job to strip directory name
string my_path = @"C:\Windows\System32";
DirectoryInfo dir_info = new DirectoryInfo(my_path);
string directory = dir_info.Name; // System32
Following solution also provide array of subset which provide specific sum (here sum = 9)
array = [1, 3, 4, 2, 7, 8, 9]
(0..array.size).map { |i| array.combination(i).to_a.select { |a| a.sum == 9 } }.flatten(1)
return array of subsets which return sum of 9
=> [[9], [1, 8], [2, 7], [3, 4, 2]]
Using .trigger("chosen:updated");
you can update the options list after appending.
Updating Chosen Dynamically: If you need to update the options in your select field and want Chosen to pick up the changes, you'll need to trigger the "chosen:updated" event on the field. Chosen will re-build itself based on the updated content.
Your code:
$("#refreshgallery").click(function(){
$('#picturegallery').empty(); //remove all child nodes
var newOption = $('<option value="1">test</option>');
$('#picturegallery').append(newOption);
$('#picturegallery').trigger("chosen:updated");
});
The current answers suggest a workaround but it's bugged me why this doesn't exist, so I've created a babel
plugin which does this.
Install it using:
npm i --save-dev babel-plugin-wildcard
then add it to your .babelrc
with:
{
"plugins": ["wildcard"]
}
see the repo for detailed install info
This allows you to do this:
import * as Things from './lib/things';
// Do whatever you want with these :D
Things.ThingA;
Things.ThingB;
Things.ThingC;
again, the repo contains further information on what exactly it does, but doing it this way avoids creating index.js
files and also happens at compile-time to avoid doing readdir
s at runtime.
Also with a newer version you can do exactly like your example:
import { ThingsA, ThingsB, ThingsC } from './lib/things/*';
works the same as the above.
Just a few minutes ago i was facing the same problem. I got the problem that is after just placing your jQuery start the other jQuery scripting. After all it will work fine.
Chapter 5 of the Bash Cookbook by O'Reilly, discusses (at some length) the reasons for the requirement in a variable assignment that there be no spaces around the '=' sign
MYVAR="something"
The explanation has something to do with distinguishing between the name of a command and a variable (where '=' may be a valid argument).
This all seems a little like justifying after the event, but in any case there is no mention of a method of assigning to a list of variables.
There are two approaches:
Using aliases; in this method you give new unique names (ALIAS) to the various columns and then use them in the PHP retrieval. e.g.
SELECT student_id AS FEES_LINK, student_class AS CLASS_LINK
FROM students_fee_tbl
LEFT JOIN student_class_tbl ON students_fee_tbl.student_id = student_class_tbl.student_id
and then fetch the results in PHP:
$query = $PDO_stmt->fetchAll();
foreach($query as $q) {
echo $q['FEES_LINK'];
}
Using place position or resultset column index; in this, the array positions are used to reference the duplicated column names. Since they appear at different positions, the index numbers that will be used is always unique. However, the index positioning numbers begins at 0. e.g.
SELECT student_id, student_class
FROM students_fee_tbl
LEFT JOIN student_class_tbl ON students_fee_tbl.student_id = student_class_tbl.student_id
and then fetch the results in PHP:
$query = $PDO_stmt->fetchAll();
foreach($query as $q) {
echo $q[0];
}
You could use LINQBridge (MIT Licensed) to add support for lambda expressions to C# 2.0:
With Studio's multi-targeting and LINQBridge, you'll be able to write local (LINQ to Objects) queries using the full power of the C# 3.0 compiler—and yet your programs will require only Framework 2.0.
The iPhone 6+ renders internally using @3x assets at a virtual resolution of 2208×1242 (with 736x414 points), then samples that down for display. The same as using a scaled resolution on a Retina MacBook — it lets them hit an integral multiple for pixel assets while still having e.g. 12 pt text look the same size on the screen.
So, yes, the launch screens need to be that size.
The 6, the 5s, the 5, the 4s and the 4 are all 326 pixels per inch, and use @2x assets to stick to the approximately 160 points per inch of all previous devices.
The 6+ is 401 pixels per inch. So it'd hypothetically need roughly @2.46x assets. Instead Apple uses @3x assets and scales the complete output down to about 84% of its natural size.
In practice Apple has decided to go with more like 87%, turning the 1080 into 1242. No doubt that was to find something as close as possible to 84% that still produced integral sizes in both directions — 1242/1080 = 2208/1920 exactly, whereas if you'd turned the 1080 into, say, 1286, you'd somehow need to render 2286.22 pixels vertically to scale well.

Read man sshd_config
for more details, but you can use the AllowUsers
directive in /etc/ssh/sshd_config
to limit the set of users who can login.
e.g.
AllowUsers boris
would mean that only the boris
user could login via ssh.
Here's a slightly shorter approach. Rather than work to create a high-precision numeric date/time, I convert the microsecond value to a string, remove the 0
, and add it to the end of the date/time string. I can easily trim the number of decimals by adjusting the string length parameter; here I use 4
to get milliseconds, but you could use 7
to get microseconds.
$t = explode(" ",microtime());
echo date("m-d-y H:i:s",$t[1]).substr((string)$t[0],1,4);
For a microtime() value of 0.98236000 1407400573
, this returns 08-07-14 01:08:13.982
.
This works:
public enum Direction {
NORTH, SOUTH, EAST, WEST;
public Direction oppose() {
switch(this) {
case NORTH: return SOUTH;
case SOUTH: return NORTH;
case EAST: return WEST;
case WEST: return EAST;
}
throw new RuntimeException("Case not implemented");
}
}
Question 1: How do create a DataTable in C#?
Answer 1:
DataTable dt = new DataTable(); // DataTable created
// Add columns in your DataTable
dt.Columns.Add("Name");
dt.Columns.Add("Marks");
Note: There is no need to Clear()
the DataTable
after creating it.
Question 2: How to add row(s)?
Answer 2: Add one row:
dt.Rows.Add("Ravi","500");
Add multiple rows: use ForEach
loop
DataTable dt2 = (DataTable)Session["CartData"]; // This DataTable contains multiple records
foreach (DataRow dr in dt2.Rows)
{
dt.Rows.Add(dr["Name"], dr["Marks"]);
}
You can use .ajaxStop()
or .ajaxComplete()
.ajaxComplete()
fires after completion of each AJAX request on your page.
$( document ).ajaxComplete(function() {
yourFunction();
});
.ajaxStop()
fires after completion of all AJAX requests on your page.
$( document ).ajaxStop(function() {
yourFunction();
});
import datetime
d = datetime.date(2012, 9, 1)
print type(d) is datetime.date
> True
You can use MutationObserver to track attribute changes including data-*
changes. For example:
var foo = document.getElementById('foo');_x000D_
_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
console.log('data-select-content-val changed');_x000D_
});_x000D_
observer.observe(foo, { _x000D_
attributes: true, _x000D_
attributeFilter: ['data-select-content-val'] });_x000D_
_x000D_
foo.dataset.selectContentVal = 1;
_x000D_
<div id='foo'></div>_x000D_
_x000D_
//Parent/Children[@ Attribute='value']/@Attribute
This is the case which can be used where element is having 2 attribute and we can get the one attribute with the help of another one.
If the difference between endTime and startTime is greater than or equal to 60 Minutes , the statement:endTime.Subtract(startTime).Minutes;
will always return (minutesDifference % 60)
. Obviously which is not desired when we are only talking about minutes (not hours here).
Here are some of the ways if you want to get total number of minutes
(in different typecasts):
// Default value that is returned is of type *double*
double double_minutes = endTime.Subtract(startTime).TotalMinutes;
int integer_minutes = (int)endTime.Subtract(startTime).TotalMinutes;
long long_minutes = (long)endTime.Subtract(startTime).TotalMinutes;
string string_minutes = (string)endTime.Subtract(startTime).TotalMinutes;
IIRC Canvas is a raster style bitmap. it wont be zoomable because there's no stored information to zoom to.
Your best bet is to keep two copies in memory (zoomed and non) and swap them on mouse click.
When the parent panel has locked property set to true, we could not change the location property and the location property will act like read only by that time.

db.Account.find().sort("UserName",pymongo.ASCENDING)
db.Account.find().sort("UserName",pymongo.DESCENDING)
Edit AppServiceProvider.php will be found at app/Providers/AppServiceProvider.php and add
